                   OUTSTANDING 11 3/4% SENIOR NOTES DUE 2008

           NEW YORK CITY TIME, ON             , 1998, UNLESS EXTENDED
 
     Splitrock Services, Inc., a Delaware corporation ("Splitrock" or the
"Company") hereby offers, upon the terms and subject to the conditions set forth
in this prospectus (the "Prospectus") and the accompanying letter of transmittal
(the "Letter of Transmittal" and, together with the Prospectus, the "Exchange
Offer"), to exchange up to an aggregate principal amount of $250,000,000 of its
new 11 3/4% Series B Senior Notes due 2008 (the "Exchange Notes") for up to an
aggregate principal amount of $250,000,000 of its outstanding 11 3/4% Senior
Notes due 2008 (the "Original Notes" and together with Exchange Notes, the
"Notes") other than those Original Notes held by an affiliate of the Company. As
of the date hereof, Original Notes in the aggregate principal amount of $11.0
million are held by an affiliate of the Company. See "The Exchange Offer Purpose
of the Exchange Offer." The Exchange Offer has been registered under the
Securities Act of 1933, as amended (the "Securities Act") pursuant to a
registration statement (the "Registration Statement") of which this Prospectus
is a part. The form and terms of the Exchange Notes are substantially identical
to the form and terms of the Original Notes, except for certain transfer
restrictions, registration rights and liquidated damages relating to the
Original Notes. The Exchange Notes will evidence the same debt as the Original
Notes and will be issued under and entitled to the benefits of an indenture
dated July 24, 1998 governing the Original Notes (the "Indenture").
 
     The Exchange Notes will bear interest at the same rate and on the same
terms as the Original Notes. Interest on the Exchange Notes will accrue from the
date of issuance (the "Exchange Date") at the rate of 11 3/4% per annum and will
be payable semi-annually on January 15 and July 15 of each year, commencing on
January 15, 1999. Holders of the Exchange Notes will also, on January 15, 1999,
receive an amount equal to the accrued interest on the Original Notes exchanged
therefor. Interest on the Original Notes accepted for exchange will cease to
accrue upon issuance of the Exchange Notes. The Company has deposited with The
Chase Manhattan Bank, as escrow agent (the "Escrow Agent"), in an escrow account
(the "Escrow Account") established pursuant to the Escrow and Disbursement
Agreement (the "Escrow Agreement") dated July 24, 1998 between the Company and
the Escrow Agent, an amount of cash or
 
                                                        (continued on next page)
 
SEE "RISK FACTORS" BEGINNING ON PAGE 19 FOR A DISCUSSION OF CERTAIN FACTORS THAT
SHOULD BE CONSIDERED IN EVALUATING AN INVESTMENT IN THE EXCHANGE NOTES.
 
THIS PROSPECTUS AND THE LETTER OF TRANSMITTAL ARE FIRST BEING MAILED TO HOLDERS
OF OUTSTANDING NOTES ON OR ABOUT             , 1998.
 
  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION NOR HAS THE COMMISSION OR ANY STATE SECURITIES COMMISSION
 PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO
                      THE CONTRARY IS A CRIMINAL OFFENSE.
 
               THE DATE OF THIS PROSPECTUS IS             , 1998.

Temporary Cash Investments (as defined) that, together with the interest
received thereon, will be sufficient to pay when due the first four semi-annual
interest payments on the Notes. The Notes will mature on July 15, 2008. The
Company may redeem the Notes, in whole or in part, on or after July 15, 2003, at
the redemption prices set forth herein, together with accrued and unpaid
interest and liquidated damages, if any, to the date of redemption. In addition,
at any time and from time to time prior to July 15, 2001, the Company may,
subject to certain requirements, redeem up to 35% of the aggregate principal
amount of the Notes (calculated after giving effect to any issuance of
Additional Notes, as defined) with the Net Cash Proceeds (as defined) of one or
more Equity Offerings (as defined) by the Company, at a redemption price equal
to 111.75% of the principal amount thereof, plus accrued and unpaid interest and
liquidated damages, if any, to the date of redemption; provided, however, that
at least 65% of the original aggregate principal amount of the Notes remains
outstanding immediately after giving effect to such redemption. The Notes will
not be subject to any sinking fund requirement. Upon the occurrence of a Change
of Control (as defined), each holder of the Notes will have the right to require
the Company to repurchase all or any part of such holder's Notes at a price
equal to 101% of the aggregate principal amount of the Notes plus accrued and
unpaid interest and liquidated damages, if any, to the date of repurchase. See
"Description of the Notes."
 
     The Notes will be Senior Indebtedness (as defined) of the Company, will
rank pari passu with all existing and future Senior Indebtedness of the Company
and will rank senior to all future Subordinated Obligations (as defined) of the
Company. The Notes will be unsecured (except that the Trustee (as defined) will
have a security interest in the Escrow Account for the benefit of the holders of
the Notes) and will therefore be effectively subordinated to all secured
indebtedness of the Company. Although the Company does not currently have any
subsidiaries, the Notes will be fully and unconditionally guaranteed on a
senior, unsecured basis by each of the Company's future Restricted Subsidiaries
(as defined) that incurs indebtedness. See "Description of the Notes -- Certain
Covenants -- Future Subsidiary Guarantors." At March 31, 1998, after giving pro
forma effect to the offering of the Original Notes and the application of the
proceeds therefrom, the Company would have had $21.1 million of indebtedness
outstanding (other than the Notes), all of which would have been Senior
Indebtedness and all of which would have been secured.
 
     The Original Notes were issued and sold on July 24, 1998, as part of a unit
offering (the "Unit Offering") in which each unit (the "Units") consisted of one
Original Note and one warrant (the "Warrants") to purchase 10.124954 shares of
common stock, par value $.001 per share (the "Common Stock"), of the Company.
The Unit Offering was not registered under the Securities Act, in reliance upon
the exemptions provided in Section 4(2) of and Rule 144A under the Securities
Act. Accordingly, the Original Notes may not be reoffered, resold or otherwise
pledged, hypothecated or transferred unless so registered or unless an
applicable exemption from the registration requirements of the Securities Act is
available. Under the Exchange Offering, the Company will accept for exchange all
Original Notes, other than Original Notes held by affiliates of the Company,
validly tendered and not withdrawn before 5:00 p.m., New York City time, on
               , 1998 unless extended by the Company, in its sole discretion, to
a date not later than                , 1998 (the "Expiration Date"). Tenders of
Original Notes may be withdrawn at any time before 5:00 p.m., New York City
time, on the Expiration Date. If the Company terminates the Exchange Offer and
does not accept for exchange any Original Notes with respect to the Exchange
Offer, the Company will promptly return the Original Notes to the holders
thereof. The Exchange Offer is not conditioned upon any minimum principal amount
of Original Notes being tendered for exchange, but is subject to certain other
conditions, which may be waived by the Company. See "The Exchange
Offer -- Certain Conditions." Notes may be tendered only in integral multiples
of $1,000.
 
     Although the Notes are eligible for trading in the Private Offerings,
Resales and Trading through Automated Linkages ("PORTAL") market, there is no
established trading market for the Notes and the Company does not intend to list
the Notes on any securities exchange or to seek approval for quotation through
any automated quotation system. There can be no assurance that an active market
for the Notes will develop. To the extent that a market for the Notes does
develop, the market value of the Notes will depend on market conditions (such as
yields on alternative investments), general economic conditions, the Company's
financial condition and other conditions. Such conditions might cause the Notes,
to the extent that they are actively traded, to trade at a significant discount
from face value. See "Risk Factors Absence of Public Market."

     The Exchange Notes are being offered hereunder to satisfy certain
obligations of the Company contained in the Exchange and Registration Rights
Agreement dated as of July 24, 1998 (the "Exchange and Registration Rights
Agreement") by and between the Company and Chase Securities Inc. (the "Initial
Purchaser") executed in connection with the sale of the Original Notes. Although
the Company has agreed to bear the expenses of this Exchange Offer, the Company
will not receive any proceeds from this Exchange Offer and no underwriter is
being used in connection with this Exchange Offer. Based on no-action letters
issued by the staff of the Securities and Exchange Commission (the "Commission")
to third parties, the Company believes that the Exchange Notes issued pursuant
to this Exchange Offer in exchange for Original Notes may be offered for resale,
resold and otherwise transferred by a holder thereof (other than (i) a broker-
dealer who purchases such Exchange Notes directly from the Company to resell
pursuant to Rule 144A or any other available exemption under the Securities Act
or (ii) a person that is an affiliate of the Company within the meaning of Rule
405 under the Securities Act), without compliance with the registration and
prospectus delivery requirements of the Securities Act if the holder is
acquiring the Exchange Notes in the ordinary course of its business and is not
participating and had no arrangement or understanding with any person to
participate in a distribution of the Exchange Notes. Holders of Original Notes
wishing to accept the Exchange Offer must represent to the Company that such
conditions have been met. Only broker-dealers who acquired the Original Notes as
a result of market-making activities or other trading activities may participate
in the Exchange Offer. Each broker-dealer that receives Exchange Notes for its
own account in exchange for the Original Notes must acknowledge that it will
deliver a Prospectus in connection with any resale of such Exchange Notes. The
Letter of Transmittal states that by so acknowledging and by delivering a
Prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of Exchange Notes received in exchange for Original
Notes if such Original Notes were acquired by such broker-dealer as a result of
market-making activities or other trading activities. The Company has indicated
its intention to make this Prospectus, as it may be amended or supplemented,
available to any broker-dealer for use in connection with any such resale for a
period of 180 days after the Expiration Date. See "Plan of Distribution."
 
     THE EXCHANGE OFFER IS NOT BEING MADE TO, NOR WILL THE COMPANY ACCEPT
SURRENDERS FOR EXCHANGE FROM, HOLDERS OF OUTSTANDING NOTES IN ANY JURISDICTION
IN WHICH THE EXCHANGE OFFER OR THE ACCEPTANCE THEREOF WOULD NOT BE IN COMPLIANCE
WITH THE SECURITIES ACT OR BLUE SKY LAWS OF SUCH JURISDICTION.
 
     NO PERSON IS AUTHORIZED IN CONNECTION WITH ANY OFFERING MADE HEREBY TO GIVE
ANY INFORMATION OR TO MAKE ANY REPRESENTATION NOT CONTAINED IN THIS PROSPECTUS
OR THE ACCOMPANYING LETTER OF TRANSMITTAL, AND, IF GIVEN OR MADE, SUCH
INFORMATION OR REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED
BY THE COMPANY. NEITHER THE DELIVERY OF THIS PROSPECTUS OR THE ACCOMPANYING

CIRCUMSTANCES CREATE ANY IMPLICATION THAT THE INFORMATION CONTAINED HEREIN IS
CORRECT AS OF ANY DATE SUBSEQUENT TO THE DATE HEREOF.

                                  THE COMPANY
 
GENERAL
 
     The Company is a provider of telecommunications services, including high
speed Internet access services, on an advanced nationwide network based on ATM
switching technology which is deployed in every operational point of presence
("POP") of the network (the "Splitrock Network" or the "Network"). The pervasive
deployment of ATM switches throughout the Network ("ATM-to-the-edge") enables
the Company to serve as a broad-based ISP through the creation of a
multi-service platform which efficiently delivers IP, frame relay and other
Internet services. This flexibility will allow the Company to expand its service
offerings to provide fully integrated data, video and voice services and to
incorporate future technological innovations into its Network architecture with
a lower incremental investment than that required by other, less flexible,
networks. The Company currently provides nationwide Internet dial access and
related services to Prodigy, the third largest U.S. ISP measured in minutes
on-line, for its approximately 900,000 subscribers. In addition, the Company has
begun providing Internet transit services to Orbis Internet Services Inc., an
Internet connection service provider to businesses ("Orbis"), and virtual
private network ("VPN") services to NetworkTwo Communications Group, a value
added network service provider ("NetworkTwo"). For the quarter ended March 31,
1998, the Company had revenues of $16.5 million.
 
     The Splitrock Network currently reaches more than 55% of U.S. households by
a local call with 56k modem access (currently the fastest modem speed
commercially available over residential phone lines), including households in
every market with a population of at least 100,000 as well as several second
tier markets. From September 1997 to April 1998, the Company deployed the
Splitrock Network infrastructure, primarily targeting densely populated markets
(the "Phase I Buildout"). The Phase I Buildout resulted in the deployment of the
nationwide ATM backbone portion of the Splitrock Network and POPs in 70
metropolitan areas across the nation. The Company is currently in the process of
constructing approximately 330 new POPs, deploying advanced processing equipment
and software to enhance and accelerate its ability to offer value added
services, such as ISDN video, web hosting and VPN, and augmenting its network
management infrastructure (the "Phase II Expansion"). The Company believes that
the Phase II Expansion will be substantially completed in the second quarter of
1999. Upon completion of the Phase II Expansion, the Network will have
approximately 400 active POPs with a physical presence in all 50 states,
reaching over 90% of U.S. households with a local call.
 
     In order to provide services to Prodigy while the Splitrock Network was
being deployed, on July 1, 1997 the Company acquired Prodigy's existing legacy
network infrastructure (the "Legacy Network") and began immediately providing
Internet dial access and related services to Prodigy for its approximately
900,000 subscribers. See "Risk Factors Reliance on Prodigy; Recent Discussions
with Prodigy." Additionally, the
 
                                        5

Company has an agreement with IBM to use IBM's network (the "IBM Global Services
Network") to cover market areas that are served neither by the Splitrock Network
nor the Legacy Network. The Company currently handles more than 750 million
minutes of Internet traffic per month for Prodigy (currently the Company's only
Internet dial access customer), with over 60% of the traffic flowing on the
Splitrock Network, approximately 30% on the IBM Global Services Network and the
remainder on the Legacy Network. As the Phase II Expansion progresses, Legacy
Network POPs will be decommissioned and access to specific IBM Global Services
Network POPs will be terminated when appropriate. Substantially all Legacy
Network POPs are expected to be decommissioned by the end of 1998 and usage of
the IBM Global Services Network is expected to be terminated by the end of the
second quarter of 1999.
 
INDUSTRY OVERVIEW
 
     The Company believes that it is well-positioned to capture revenue
opportunities in the growing Internet services market. As a broad-based ISP, the
Company utilizes an advanced ATM-to-the-edge Network to offer services that
either directly address Internet connectivity (dial access and transit) or which
leverage Internet technology to provide cost-effective alternatives to
traditional corporate network solutions (VPN). While the Company is considering
broadening its service offerings to optimize Network utilization, the Company
believes that a significant amount of its revenues for the foreseeable future
will continue to be derived from Internet related applications.
 
     The Internet services industry is one of the fastest growing segments of
the global telecommunications market. Forrester estimates that the U.S. market
for Internet and related services, including advanced Internet applications such
as VPN, voice communications, fax and video conferencing, was approximately $6.2
billion in 1997 and will grow to approximately $49.7 billion in 2002, reflecting
a compound annual growth rate of over 50%. The Company believes that Internet
dial access and transit services, VPN services and enhanced business services
represent three of the fastest growing segments of the industry.
 
     Internet access services represent the means by which ISPs interconnect
either businesses or individual consumers to the Internet's resources or to
corporate intranets and extranets. Access services include dial-up access for
individuals and small businesses and high-speed dedicated access (transit
services) used primarily by mid-sized and larger organizations. According to
Forrester, business access services are projected to grow at a compound annual
growth rate of approximately 75%, from approximately $1.0 billion in 1997 to
approximately $16.0 billion in 2002.
 
     In addition, the Company believes that many businesses desire to utilize
VPNs as a lower-cost alternative to certain traditional telecommunications
services. Historically, many corporations established and maintained their own
private wide-area networks ("WANs") to provide network-based services, such as
transaction processing, to their customers and to coordinate operations between
employees, suppliers and business partners. These networks, which have
traditionally required the use of leased telephone lines with dedicated
bandwidth and the purchase of vendor-specific networking equipment and software,
are inherently expensive to set up, operate and maintain. The Company believes
that VPNs present a cost-effective alternative to WANs since VPNs (i) eliminate
the need to invest significant amounts in proprietary equipment and software,
(ii) securely and efficiently connect multiple, geographically dispersed
locations, (iii) provide global remote access capabilities and (iv) offer a full
range of value added services, such as videoconferencing, that meet a company's
particular networking needs.
 
     In addition to Internet access and VPN services, business customers
increasingly are seeking a variety of enhanced products and applications to take
full advantage of the Internet. The principal enhanced services currently
available to companies are Web hosting, including hosting of intranet sites,
e-mail outsourcing, e-mail broadcast and security. Forrester forecasts that
enhanced business services revenues will grow from approximately $0.4 billion in
1997 to approximately $10.5 billion in 2002, representing a compound annual
growth rate of 92%. See "Industry Overview."

COMPETITIVE ADVANTAGES
 
     Since July 1997, the Company has provided Internet dial access services to
Prodigy for its approximately 900,000 subscribers. The Company believes it
benefits from the following competitive advantages which will assist it in
implementing its business strategy:
 
          Flexible and Efficient New Network Infrastructure. The Splitrock
     Network is designed to provide reliable, flexible and efficient services to
     the Company's current and future customers. Since the Splitrock Network is
     newly-designed (and not based on or an upgrade to an older network), the
     Company believes the Network contains many features that are not present in
     older networks and is able to flexibly incorporate future developments and
     innovations. Older networks were typically designed to provide one type of
     service, such as voice or data, and are less efficient at carrying other
     traffic. Unlike many networks which deploy ATM technology only along the
     core sites in the backbone, the Splitrock Network deploys ATM-to-the-edge
     at every core site, hub site and remote site. See "Business Splitrock's
     Network." Each POP is supported by the Lucent LDR200 switch, which the
     Company believes provides significant quality of service advantages over
     typical ATM backbone switches. Management believes that the Network
     contains more ATM-based switches than that of any other commercial network.
     This pervasive use of ATM technology and the Lucent LDR200 switch enables
     the Company to create a multi-service platform which delivers IP, frame
     relay and other Internet services. In addition, ATM-to-the-edge provides
     additional capabilities to expand the Company's service offerings to
     provide fully integrated data, video and voice services and to incorporate
     future technological innovations into the Splitrock Network architecture
     with a lower incremental investment than that required by other, less
     flexible, networks.
 
          Provider of Wholesale Internet Dial Access and International
     Services. The Company currently provides wholesale Internet dial access
     services to Prodigy for its approximately 900,000 subscribers. The Company
     intends to market Internet dial access services directly to ISPs rather
     than to individual end-users. As a result, unlike many providers of network
     services, the Company does not intend to compete against its ISP customers,
     thereby broadening the potential customer base to include those ISPs
     unwilling to strengthen their competitors with their own network business.
     Furthermore, the Company believes it will be viewed as a non-competing
     vendor and, thus a potential partner, by major foreign and regional
     telecommunications carriers, providing an alternative to their primary U.S.
     competitors for delivering data, video and voice services.
 
          Experienced Management Team. The Company's co-founders, Kwok L. Li,
     Chairman of the Board and Chief Technical Officer, and William R. Wilson,
     President and Chief Executive Officer, have assembled a management team
     with significant data and voice communications experience. The 10 most
     senior executives and managers of the Company have an average of over 12
     years experience in the data and voice communications industry. Previously,
     Mr. Li and Mr. Wilson were both senior executives at the predecessor
     corporation of WilTel Communications LLC ("WilTel"), a wholesale provider
     of telecommunications services. During their tenure WilTel designed,
     constructed, developed and managed modern packet switched networks
     (including frame relay and ATM) and marketed related services. At the time
     of the sale of Yurie to Lucent in May 1998, Mr. Li was a Director, Vice
     Chairman and Chief Technical Officer at Yurie, where he created and
     designed the Lucent LDR200 switch which is a key component of the Splitrock
     Network.
 
BUSINESS STRATEGY
 
     Key elements of the Company's business strategy include:
 
          Complete the Expansion of the Advanced Network Infrastructure. The
     Company has designed, deployed and is in the process of expanding the
     Splitrock Network, an advanced nationwide telecommunications network based
     on ATM-to-the-edge switching technology. Through March 31, 1998, the
     Company had spent approximately $23.9 million on the Phase I Buildout,
     which was substantially completed in April 1998, and $12.7 million on the
     Phase II Expansion. The Company anticipates that completion of the Phase II
     Expansion will require an additional $141.1 million of capital
     expenditures. The Company expects to spend approximately $47.4 million to
     construct approximately 330 additional
                                        7
<PAGE>   9
 
     POPs, approximately $81.5 million to deploy advanced processing equipment
     and software to enhance and accelerate the Company's ability to provide
     value added services, such as ISDN video, web hosting and VPN, and
     approximately $12.2 million to augment the Company's network management
     infrastructure. Of these amounts, the Company has spent $1.7 million since
     March 31, 1998. The Company believes that having ATM-to-the-edge results
     in: (i) a more easily upgradeable network; (ii) the ability to efficiently
     add new services at a lower incremental investment; (iii) improved network
     reliability; (iv) interoperability with other network platforms; and (v)
     improved network manageability.
 
          Offer a Comprehensive Range of Services to Optimize Network
     Utilization. Given the fixed cost nature of the Splitrock Network's
     infrastructure, the Company seeks to increase total network utilization
     primarily by targeting providers of business services (daytime intensive
     traffic) and, to a lesser extent, providers of consumer services (evening
     intensive traffic) to balance the Network's usage throughout a 24-hour
     period. The Network's flexibility will provide for service innovation
     (including data, video and voice services) with lower incremental
     investment than less flexible networks. To offer new services, the Company
     will only need to add the appropriate protocol processors and billing and
     service management systems without changes to the core ATM switching
     platform. Therefore, the Company believes it will be able to maximize
     Network utilization by offering both daytime business-oriented services
     (such as video conferencing and VPN services) and evening-time
     consumer-oriented services (such as Internet dial access services). The
     ability of the Company to offer a wide range of services will enhance its
     ability to optimize traffic at all times of the day, thereby increasing
     revenue and profitability. As its business strategy is implemented, the
     Company will evaluate offering complementary services as they are required
     by its customer base.
 
          Development of Advanced Business Support Systems. Through the
     development of scalable business support systems, the Company believes that
     it has the opportunity to establish a competitive advantage relative to
     traditional network service providers. Traditional network service
     providers typically operate extensive legacy business support systems with
     compartmentalized architectures that limit their ability to scale rapidly
     and introduce enhanced services and features. In connection with the
     expansion of the Splitrock Network the Company is creating business support
     systems with an architecture designed to maximize both reliability and
     scalability. All database and billing systems will run on a PC or UNIX
     distributed architecture rather than centralized mainframe systems.
 
          Expand Target Market Opportunities. IDC estimates that the total
     number of U.S. companies with Internet access will grow from an estimated
     1.5 million, or 20.0% of total U.S. companies, in 1996 to 4.1 million, or
     53.0% of total U.S. companies, in 2000. IDC also estimates that the number
     of U.S. households with a personal computer and a modem will grow from an
     estimated 8.8 million, or 24.0% of all U.S. households with a personal
     computer in 1996, to 39.4 million, or 58.0% of all U.S. households with a
     personal computer, in 2000. IDC estimates that there are currently over
     4,000 ISPs in the U.S., consisting of national, regional and local
     providers, of which the Company believes only a small percentage have
     access to their own nationwide backbone network infrastructure. The Company
     intends to capitalize on this expected growth in demand for network
     services by aggressively marketing its services through a variety of
     distribution channels and evaluating strategic alliances and acquisitions
     as they present themselves. The Company believes that utilizing a range of
     distribution channels will enable it to cost-effectively reach a broad base
     of potential customers. The Company currently intends to develop and use a
     direct sales force (which it expects to begin hiring late in the second
     half of 1998) to attract ISPs, carriers, value added service providers and
     medium and large businesses. In addition, the Company intends to use
     alternative distribution channels, including agents, resellers and
     wholesalers, to gain access to a substantially larger base of potential
     customers than the Company could otherwise initially address through its
     direct sales force. Through the combination of a direct sales force and
     alternative distribution channels, the Company will seek to rapidly
     increase revenue-producing traffic on its Network.
 
          The Company also intends to evaluate strategic alliances and
     acquisitions that could provide additional traffic over the Splitrock
     Network. While the Company is primarily focused on the domestic services
     market, it believes the demand for Internet services outside the U.S. will
     grow over the next few years. As a result, the Company will evaluate
     opportunities, primarily in Latin America, to partner with
                                        8
<PAGE>   10
 
     strong, established telecommunications service providers. For example, the
     Company will consider entering into international alliances to originate
     and terminate international traffic on the Splitrock Network.
 
          Provide Superior Comprehensive Customer Service. Splitrock believes
     that superior customer service is a critical element in attracting and
     retaining customers, and expanding value added services to existing
     customers. In particular, the Company believes it is critical to maintain
     two geographically dispersed Network Operations Centers ("NOCs"), each of
     which is able to monitor the entire Network and provide rapid problem
     resolution. The Company has established a 24-hours per day, seven days per
     week NOC at its Yorktown, NY facility. In addition, a new 24-hours per day,
     seven days per week NOC recently became fully operational at The Woodlands,
     TX facility.
 
RECENT DEVELOPMENTS
 
     During the three months ended June 30, 1998, the Company began the Phase II
Expansion, the Company's largest build-out initiative to date. Until the
completion of the Phase II Expansion (expected in the second quarter of 1999),
the Company will continue to utilize the IBM Global Services Network. On April
1, 1998, the Company renegotiated the usage contract for the IBM Global Services
Network, which management believes will increase charges related to the IBM
Global Services Network by approximately 45% for the second quarter of 1998 as
compared to the first quarter of 1998. The Company's results for the second
quarter of 1998 are not yet available, however the Company expects to record
substantially lower EBITDA (as defined) than in the first quarter of 1998. This
expected lower EBITDA amount is consistent with the Company's expectations and
business plan. For the months of April and May of 1998, the Company recorded
revenues of $5.2 million and $5.3 million, respectively, net losses of $3.2
million and $2.8 million, respectively, and EBITDA of $(2.5) million and $(1.9)
million, respectively. The decrease in revenues in April and May from March of
1998 was primarily the result of the switch in the calculation of charges for
Prodigy services from the Usage-Based Rate (as defined) to the Subscriber-Based
Rate (as defined) and a slight decrease in total Prodigy subscribers. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations." The larger EBITDA deficit in April and May of 1998 compared to each
of the months in the first quarter of 1998 was primarily the result of the lower
revenues and the increased usage charges related to the IBM Global Services
Network described above and increased line and telecommunications charges
relating to the expansion of Splitrock Network. The Company expects to continue
to incur negative EBITDA through the completion of the Phase II Expansion.
Thereafter, the Company's ability to generate positive EBITDA will depend on the
successful implementation of its business strategy.
 
     In cooperation with Telefonos de Mexico, S.A. de C.V. ("Telmex"), Mexico's
primary phone company, the Company expects to install a POP in Monterrey, Mexico
in August 1998. This POP is currently intended only to test connectivity between
the Splitrock Network and Telmex's data network. Should testing prove
successful, the Company will consider entering into formal negotiations to
provide services to Telmex, including carrying all or a portion of Telmex's U.S.
bound data traffic over the Splitrock Network.
 
     Carso Global Telecom, S.A. de C.V. ("Carso") is the controlling stockholder
of Prodigy and a significant stockholder of Telmex. Orient Star Holdings
("Orient Star"), a wholly owned subsidiary of Carso, owns 20.0 million shares,
or 25.7%, of the Common Stock of the Company and holds a warrant, exercisable
through September 18, 1998, to acquire an additional 5.0 million shares which
would result, if exercised, in Orient Star holding approximately 30.2% of the
Common Stock of the Company. The Company expects that this warrant will be
exercised. See "Management Certain Relationships and Related Transactions."
 
THE PRIVATE PLACEMENT AND USE OF PROCEEDS
 
     The Company sold the Units, which included the Original Notes, on July 24,
1998 to Chase Securities Inc. (the "Initial Purchaser"), reflected in the
offering memorandum dated July 21, 1998 (the "Offering Memorandum"). The Initial
Purchaser thereupon offered and sold the Units that included Original Notes in
the aggregate principal amount of $250.0 million to certain qualified buyers and
Units that included Original
 
                                        9
<PAGE>   11
 
Notes in the aggregate principal amount of $11.0 million to Linsang Partners
L.L.C., an affiliate of the Company ("Linsang"). The $252.9 million of net
proceeds the Company received in connection with the sale of the Original Notes,
which were sold as units together with certain warrants (the "Warrants") to
purchase an aggregate of 2,642,613 shares of the Company's common stock ("Common
Stock"), as described in the Offering Memorandum were used as follows: (i)
approximately $56.6 million was deposited in escrow to pay the first four
semi-annual interest payments on the Notes, (ii) approximately $11.0 million was
used to refinance certain stockholder indebtedness, (iii) approximately $1.5
million was used to repay debt owed to a supplier, and (iv) the remainder will
be used to finance capital expenditures to complete the Phase II Expansion (as
defined) of the Splitrock Network (as defined), expected to be approximately
$139.4 million, and for general corporate purposes. In addition, a portion of
the net proceeds may be used to make investments in or acquisitions of certain
businesses or assets. See "Use of Proceeds." The Warrants have an exercise price
of $.01 per share, and are exercisable at any time on or after the first
anniversary of the date of original issuance of the Warrants and prior to the
maturity date of the Notes. The Warrants are not being registered in the

                             the Exchange Notes acquired by such person and
                             cannot rely on the position of the staff of the

                             the holder understands that a secondary resale
                             transaction described in clause (iii) above and any

                             is required to acknowledge in the Letter of

                             Prospectus, the holder will not be deemed to admit
                             that it is an "underwriter" within the meaning of
                             the Securities Act. See "The Exchange

Beneficial Owners..........  Any beneficial owner whose Original Notes are
                             registered in the name of a broker, dealer,
                             commercial bank, trust company or other nominee and
                             who wishes to tender such Original Notes in the
                             Exchange Offer should contact such registered
                             holder promptly and instruct such registered holder
                             to tender on such beneficial owner's behalf. See

                             resold only (i) to the Company, (ii) pursuant to
                             Rule 144A or Rule 144 under the Securities Act or
                             pursuant to some other exemption under the
                             Securities Act, or (iii) pursuant to an effective
                             registration statement under Securities Act. See
                             "The Exchange Offer -- Consequences of Failure to
                             Exchange."
 
THE NOTES
 
The Exchange Notes.........  The Exchange Offer applies to Original Notes in the
                             aggregate principal amount of $250.0 million. The
                             form and terms of the Exchange Notes are the same
                             as the form and terms of the Original Notes except
                             that (i) the exchange will have been registered
                             under the Securities Act and, therefore, the
                             Exchange Notes will not bear legends restricting
                             their transfer pursuant to the Securities Act and
                             (ii) holders of the Exchange Notes will not be
                             entitled to certain rights of holders of the
                             Original Notes under the Exchange and Registration
                             Rights Agreement. Such rights will terminate upon
                             consummation of the Exchange Offer. The Exchange
                             Notes will represent the same debt as the Original
                             Notes (which they replace) and will be issued
                             under, and be entitled to the benefits of, the
                             Indenture. See "Description of the Notes."

                             received thereon, will be sufficient to pay when
                             due the first four semi-annual interest payments on
                             the Notes, with any remaining balance to be
                             retained by the Company. The Notes will be
                             collateralized by a first priority and exclusive
                             security interest in the Escrow Account. See
                             "Description of the Notes -- Disbursement of Funds;
                             Escrow Account."

                             any subsidiaries.

                             redeem the Notes prior to July 15, 2003. On or

                             redeem up to 35% of the original aggregate
                             principal amount of the Notes (calculated after
                             giving effect to any issuance of Additional Notes,
                             as defined) with the Net Cash Proceeds of one or

                             dated damages, if any, to the date of redemption;
                             provided, however, that at least 65% of the
                             original aggregate principal amount of the Notes
                             remains outstanding immediately after each such
                             redemption (calculated after giving effect to any
                             issuance of Additional Notes). See "Description of
                             the Notes -- Optional Redemption."
 
Change of Control..........  Upon the occurrence of a Change of Control, each
                             holder of the Notes will have the right to require
                             the Company to repurchase all or any part of such
                             holder's Notes at a price equal to 101% of the
                             aggregate principal amount of the Notes plus
                             accrued and unpaid interest and liquidated damages
                             thereon, if any, to the date of repurchase. See
                             "Description of the Notes -- Change of Control."
 
Ranking....................  The Notes will be Senior Indebtedness of the
                             Company, will rank pari passu with all existing and
                             future Senior Indebtedness of the Company and will
                             rank senior to all future Subordinated Obligations
                             of the Company. The Notes will be unsecured (except
                             that the Trustee will have a security interest in
                             the Escrow Account for the benefit of the Holders
                             of the Notes) and will therefore be effectively
                             subordinated to all secured indebtedness of the
                             Company. At March 31, 1998, after giving pro forma
                             effect to the offering of the Notes and the
                             application of the proceeds therefrom, the Company
                             would have had $21.1 million of indebtedness
                             outstanding (other than the Notes), all of which
                             would have been Senior Indebtedness and all of

           SUMMARY HISTORICAL AND UNAUDITED PRO FORMA FINANCIAL DATA
 
     The following table sets forth summary historical and unaudited pro forma
financial data of the Company. The historical statement of operations and other
financial data for the period from inception (March 5, 1997) through December
31, 1997 and the historical balance sheet data as of December 31, 1997 have been
derived from, should be read in conjunction with and are qualified in their
entirety by reference to the audited financial statements, including the notes
thereto, included elsewhere in this Prospectus. The historical statement of
operations and other financial data for the three months ended March 31, 1998
and the historical balance sheet data as of March 31, 1998 have been derived
from, should be read in conjunction with and are qualified in their entirety by
reference to the unaudited condensed financial statements, including the notes
thereto, included elsewhere in this Prospectus which have been prepared on a
basis consistent with the audited financial statements and in the opinion of
management include all adjustments, consisting solely of normal, recurring
adjustments, necessary to present fairly the information contained therein. The
historical quarterly statement of operations data for the three months ended
June 30, 1997, September 30, 1997 and December 31, 1997 have been derived from
the Company's accounting records and have been prepared on a basis consistent
with the audited financial statements and in the opinion of management include
all adjustments, consisting solely of normal, recurring adjustments, necessary
to present fairly the information contained therein. The summary historical
financial data are not necessarily indicative of the operating results to be
expected in future periods.
 
     The following table also presents certain summary unaudited pro forma
financial data of the Company for the period from inception (March 5, 1997) to
December 31, 1997 and the three months ended and as of March 31, 1998, which
give effect to the Unit Offering and the application of the proceeds therefrom
as if they had occurred on March 5, 1997 and January 1, 1998, respectively, in
the case of the statement of operations data, and March 31, 1998, in the case of
the balance sheet data. The summary unaudited pro forma financial data do not
purport to be indicative of the results that actually would have been obtained
had the Unit Offering been consummated on the assumed dates and they are not
necessarily indicative of operating results to be expected in future periods.
 
     The following summary historical and unaudited pro forma financial data
should be read in conjunction with the historical financial statements of the
Company and the notes thereto included elsewhere in this Prospectus, "Selected
Historical and Unaudited Pro Forma Financial Data" and "Management's Discussion
and Analysis of Financial Condition and Results of Operations."

</TABLE>
 
- ---------------
 
(1) Prior to January 1998, certain staffing positions were filled by Prodigy
    employees who were subcontracted to the Company. In the fourth quarter of
    1997, the Company recorded a severance charge related to the elimination of
    13 of these positions.
 
(2) Capital expenditures include equipment purchased through capital leases of
    $26.2 million and $2.2 million for the period from inception (March 5, 1997)
    through December 31, 1997 and for the three months ended March 31, 1998,
    respectively.
 
(3) EBITDA is defined as net income (loss) plus net interest expense, provision
    for income taxes, depreciation and amortization and severance costs. EBITDA
    is presented as it is commonly used by certain investors to analyze and
    compare operating performance and to determine a company's ability to
    service and/or incur debt. However, EBITDA should not be considered in
    isolation or as a substitute for net income, cash flows or other income or
    cash flow data or as a measure of a company's profitability or liquidity and
    is not a measure in accordance with generally accepted accounting
    principles. EBITDA is not necessarily comparable with similarly titled
    measures reported by other companies.
 
(4) Pro forma interest expense assumes that the Unit Offering and the
    application of the net proceeds therefrom had occurred on the first day of
    the period presented. In addition to the stated interest rate on the Notes,
    pro forma interest expense includes amortization of deferred issuance costs
    and discount on the Notes related to the Warrants. Pro forma interest
    expense does not include the pro forma effect of interest income which would
    have been earned on excess cash for the period from inception (March 5,
    1997) through December 31, 1997 and for the three months ended March 31,
    1998.
 
(5) Pro forma balance sheet data assumes the Unit Offering and the application
    of the net proceeds therefrom had occurred on March 31, 1998.
 
                                       17

(6) In addition to the indebtedness set forth in the above table, at July 15,
    1998 the Company owed Ericsson $1.5 million (which was repaid with the
    proceeds of the Unit Offering) and owed a stockholder $11.0 million
    (increased from $6.0 million on March 31, 1998), which was refinanced in
    connection with the Unit Offering. After giving effect to such repayment and
    refinancing, pro forma cash and cash equivalents would have been $186.1
    million. Pro forma long term debt and capital lease obligations is net of
    $2.9 million discount to the principal amount of the Notes attributable to
    the Company's estimate of the value of the Warrants issued in connection
    with the Unit Offering.
 
(7) As of December 31, 1997, the Company had an outstanding letter of credit in
    the amount of $3.5 million. This letter of credit was secured by the amount
    in the restricted cash account. In the first quarter of 1998, the Company
    exercised its early purchase option with regard to the related capital lease
    and the letter of credit was retired. Pro forma amount represents escrowed
    funds that, together with interest received thereon, will be sufficient to
    pay when due the first four semi-annual interest payments on the Notes.
 
(8) Includes $2.9 million attributable to the Company's estimate of the value of
    the Warrants. Such estimate was based on a valuation of the Common Stock as
    of December 31, 1997 by a third party valuation firm. See
    "Management -- Executive Compensation." No assurance can be given that the
    value allocated to the Warrants is indicative of the price at which the
    Warrants may actually trade.

     The Company was formed in March 1997 and has a limited history of
operations. Thus, historical information set forth herein may not be indicative
of the Company's future operating results and financial condition. In view of
the limited operating history of the Company, the Company remains vulnerable to
a variety of business risks generally associated with start-up companies, some
of which are beyond the control of the Company. Failure to continue to upgrade
operating and financial controls or systems or unexpected difficulties
encountered during expansion could adversely affect the Company's business,
financial condition and results of operation. Since June 1997, the Company has
recruited and hired key members of management in the areas of operations and
administration. As a result, the key members of the Company's management team
have worked together for only a short time. See "Management."
 
     The Company reported EBITDA (as defined) of approximately $(6.3) million
and $(0.6) million for the period from inception (March 5, 1997) to December 31,
1997 and the three months ended March 31, 1998, respectively (net losses
amounted to $10,121 and $3,698 for the same periods). On a pro forma basis after
giving effect to the offering of the Original Notes and the application of the
net proceeds therefrom, the Company would have reported net losses of $36.3
million and $11.5 million for the period from inception (March 5, 1997) to
December 31, 1997 and the three months ended March 31, 1998, respectively. The
Company expects such net losses to continue as the Company focuses on increasing
its customer base, implementing its business strategy and developing new
services which will require it to incur significantly increased expenses for
marketing, network infrastructure, accounting, billing and other financial
control systems and personnel. Such expenses are expected to adversely impact
cash flow and operating performance. See "Summary -- Recent Developments." There
can be no assurance that the Company will generate sufficient revenues such that
the Company's operations will become profitable or generate positive cash flows
in the future. If the Company cannot achieve operating profitability or positive
cash flows from operating activities, it may not be able to meet its working
capital or debt service requirements, including its obligations under the Notes,
which would cause an event of default under the Indenture. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
DIFFICULTIES IN EXPANDING AND OPERATING THE SPLITROCK NETWORK
 
     The Company's ability to generate positive cash flows from operations will
depend upon the successful, timely and cost-effective expansion of the Splitrock
Network, the successful operation of the Splitrock Network and the Company's
ability to continue to attract customers. The expansion of the Splitrock Network
is subject to a variety of uncertainties and contingencies, including site and
facility acquisitions, the purchase and installation of network equipment, the
timely performance by its suppliers and third-party contractors of their
obligations, obtaining local telecommunications connections, and network
testing. Although the Company believes that its cost estimates and the expansion
schedule are reasonable, there can be no assurance that the actual construction
costs or time required to expand the Splitrock Network will not substantially
exceed current estimates. The inability of the Company to complete the Phase II
Expansion or obtain the necessary third-party telecommunication connections on a
timely or cost-efficient basis would have a material adverse effect on the
Company's financial condition and results of operations.
 
     The Company has limited experience managing a telecommunications network.
The operation of the Splitrock Network is a significant undertaking.
Administrative, technical, operational and other problems that could arise,
including as a result of increasing traffic volume and equipment and software
failures, may be more difficult to address and solve due to the significant size
and complexity of the Network. The Company has experienced technical problems
which have led to significant service interruptions and failures. See
"-- Reliance on Prodigy; Recent Discussions with Prodigy." The inability of the
Company to effectively
 
                                       19
<PAGE>   21
 
operate the Network and to quickly respond to problems as they occur would have
a material adverse effect on the Company's financial condition and results of
operations.
 
     The Company's financial performance will further depend on its ability to
generate significant customer traffic. The Company currently derives
substantially all of its revenues from Prodigy. Although the Company has begun
receiving revenues from two additional customers, the Company expects that for
the foreseeable future Prodigy will remain its dominant customer and a small
number of customers will continue to account for all the Company's revenue. See
"Business -- Customers." In order to broaden its customer base, the Company will
need to expand its marketing and sales efforts and staff. See "-- Ability to
Manage Growth." The inability to significantly increase customer traffic would
have a material adverse effect on the Company.
 
     The Company anticipates that even after the Phase II Expansion, future
expansions and adaptations of the Network's infrastructure, including the
electronic and software components used therein, will be necessary in order to
respond to growth in the number of customers served, increased demands to
transmit larger amounts of data, changes in its customers' service requirements
and technological advances by competitors. The expansion and adaptation of the
Splitrock Network will require substantial financial, operational and managerial
resources. There can be no assurance that the Company will be able to expand or
adapt the Splitrock Network to meet the evolving standards, demands and
requirements of its customers or technological advances of its competitors on a
timely basis and at a commercially reasonable cost, if at all, or that the
Company will be able to deploy successfully any expanded and adapted Network
infrastructure. The Company believes, based on current plans and assumptions
relating to its operations, that the net proceeds of the Unit Offering, together
with its existing financial resources and future borrowings from a stockholder,
if any, will be sufficient to fund the Company's growth and operations. In the
event that the Company's plans or assumptions change or prove to be inaccurate,
the Company may be required to seek alternative sources of financing. There can
be no assurance that the Company would be able to obtain additional financing on
acceptable terms, or at all. Any failure by the Company to expand or adapt the
Splitrock Network to the needs of its customers could have a material adverse
effect on the Company's financial condition and results of operations.
 
RELIANCE ON PRODIGY; RECENT DISCUSSIONS WITH PRODIGY
 
     Pursuant to the Prodigy Agreement (as defined), the Company currently
provides certain network and related services, including Internet dial access
services, to Prodigy for its subscribers. Substantially all of the Company's
revenue to date has been derived from Prodigy under this agreement. Although the
Company has recently begun providing services to two additional customers and
expects to attract additional customers in the short-term, the Company expects
that for the foreseeable future Prodigy will remain its dominant customer and a
small number of customers will continue to account for all the Company's
revenue.
 
     Prodigy is currently the third largest U.S. ISP measured in minutes
on-line. Launched in 1984 as a joint venture between IBM and Sears, Prodigy is
currently controlled by Carso, which indirectly owns 20.0 million shares, or
25.7%, of the Common Stock of the Company and a warrant, exercisable through
September 18, 1998, to acquire an additional 5.0 million shares, which, if
exercised, would result in Carso indirectly holding approximately 30.2% of the
Common Stock of the Company. Samer Salameh, the President and Chief Executive
Officer of Prodigy, is a member of the Board of Directors of the Company. See
"Principal Stockholders". Since Prodigy is a private company, limited financial
or other information regarding Prodigy is publicly available. In addition, the
Prodigy Agreement provides for only very limited information regarding Prodigy
to be provided to the Company. Therefore, the Company is unable to assess with
any certainty the financial condition or results of operations of Prodigy or
whether Prodigy will continue to operate as a financially solvent company or
remain able to pay amounts owed under the Prodigy Agreement. Furthermore,
Prodigy operates in a highly competitive environment. Prodigy competes with a
wide range of national, regional and local ISPs. Due to the limited available
information regarding Prodigy, the Company is unable to predict whether Prodigy
will remain competitive in the ISP marketplace. If competitive or other factors
were to result in a reorganization, bankruptcy, liquidation or similar
proceeding with respect to Prodigy or otherwise result in Prodigy being unable
to pay amounts due under the Prodigy Agreement the Company's financial position,
results of operations and ability to pay principal and interest on the Notes
would be materially adversely affected. Furthermore, if due to competitive or
other factors the number of Prodigy subscribers or
                                       20
<PAGE>   22
 
usage by subscribers were to decrease, the Company would receive less revenue
under the Prodigy Agreement, which could have a material adverse effect on the
Company's financial position and results of operations. In addition, Prodigy is
operating in an industry undergoing rapid consolidation. Any acquisition or
merger involving Prodigy and a company with an alternative source of network
services could result in Prodigy exercising its option to terminate the Prodigy
Agreement and therefore have a material adverse effect on the Company. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Prodigy Transactions."
 
     The Prodigy Agreement allows Prodigy to terminate its arrangement with the
Company on twelve months notice upon the payment of a termination charge. The
Prodigy Agreement also allows Prodigy to terminate its arrangement with the
Company on 45 days notice without payment if the Company defaults, following a
cure period, with respect to certain performance standards contained in the
Prodigy Agreement. In addition, the Prodigy Agreement provides for arbitration
to resolve certain other disputes including a default by the Company with
respect to certain financial covenants. Such arbitration could lead to a
termination of the Prodigy Agreement. The Company believes that, based on
current market conditions, if the relationship with Prodigy were terminated, it
could find new customers to replace the resulting loss of traffic. There can be
no assurance that there will not be a change in market conditions or that the
Company will be able to secure additional traffic should the relationship with
Prodigy be terminated. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business -- Customers."
 
     The Company is currently Prodigy's sole supplier of network services. As a
result, Prodigy is dependent on the Company to provide local Internet dial
access services to its subscribers. As such, Prodigy closely monitors the
quality of the services provided by the Company since it directly impacts
Prodigy's business and financial performance.
 
     As part of its expansion plan, in January 1998 the Company began migrating
Prodigy subscribers from the Legacy Network to the Splitrock Network. In
addition to technical problems and network failures which occur from time to
time in the ordinary course of operating a telecommunications network, in
connection with the rapid migration of Prodigy subscribers from the Legacy
Network to the Splitrock Network during the first quarter of 1998, the Company,
and therefore Prodigy, experienced significant service interruptions and
failures, the most prolonged and serious of which occurred in February, March
and April of 1998. These service interruptions and failures were primarily due
to a faulty modem code that, among other things, resulted in a significant
number of Prodigy subscribers who called into the Splitrock Network receiving
busy signals when, in fact, there was sufficient capacity available to handle
the calls. At the time of these service interruptions, the Company had
inadequate staffing levels and procedures in place to detect or respond to the
situation in a timely manner. As a result, the modem related problems resulted
in an unfavorable call failure rate compared to industry norms. The Company
believes that it and its third-party modem vendor have corrected the faulty
modem code, although no assurance can be given in this regard. In addition, the
Company believes that it has achieved staffing levels in its NOCs adequate to
detect and address any such future service interruptions or failures.
 
     Since February 1998 Prodigy has expressed repeated and serious concerns
regarding the Company's ability to deliver network services at a level of
quality and reliability necessary to sustain Prodigy's business and expected
growth. In particular, Prodigy has indicated that it believes that, due to the
Company's Network problems during the first quarter of 1998, Prodigy lost a
significant number of subscribers and the associated revenues and incurred
substantial costs. In addition, Prodigy has expressed serious concern about the
impact the Company's Network problems have had on the perception of Prodigy in
the industry. In May 1998, Prodigy notified the Company that unless the Company
was able to improve Network quality and access availability, it would be forced
to use alternate network service providers.
 
     In connection with these discussions Prodigy raised a number of service and
technology related issues that it believes require prompt resolution. These
issues include, among other things, providing backup capacity to the Splitrock
Network (including through other providers' networks), automatic rollover
services to alternate access phone numbers, methods for limiting service
abusers, and network time-out circumventions. In addition, Prodigy has proposed
a number of amendments to the Prodigy Agreement including, among other
 
                                       21
<PAGE>   23
 
things, modifying the current fee structure to a monthly fee based on
utilization of the Network, imposing more stringent financial penalties on the
Company in the event of Network interruptions, and exclusivity until the Network
is stable (i.e., a prohibition on the Company providing Internet dial access
services to Prodigy's large consumer-oriented ISP competitors).
 
     Prodigy and the Company have had several meetings with regard to these
issues and have agreed to continue to have frequent periodic meetings. As a
result of these meetings, the Company has implemented a number of additional
procedures and business support systems. For example, the Company has
implemented network management systems that enable real time monitoring of the
Network and has established more frequent access to Prodigy subscriber-related
data on Network performance. Certain issues, however, remain under discussion.
Although the Company believes that it will resolve the outstanding issues
between the Company and Prodigy, until these issues are resolved, the future of
the Company's relationship with Prodigy is uncertain and there can be no
assurance that further discussions with Prodigy will not result in a termination
of the relationship, increased costs to the Company or amendments to the Prodigy
Agreement that are unfavorable to the Company. The loss of Prodigy as a customer
or any such increased costs or amendments to the Prodigy Agreement could have a
material adverse effect on the Company.
 
     Prior to solutions implemented by the Company and its third-party modem
vendor, in April 1998 Inverse, an independent Internet testing group, indicated
that Prodigy had a call failure rate for the March 1998 reporting period that
was almost double that of Inverse's reported industry average, an 18.3% call
failure rate versus 9.4%, respectively, during the evening hours in which most
Prodigy traffic occurs. In June 1998, Inverse indicated that for the May
reporting period Prodigy had a call failure rate that was lower than the Inverse
industry average during such evening hours. The Company believes that its
improvement was primarily due to the solutions implemented by it and its
third-party modem vendor. In July 1998, Inverse indicated that for the June
reporting period Prodigy had a call failure rate above the Inverse industry
average during such evening hours. Prodigy's higher rate was in part due to
problems Prodigy experienced with certain log-on software during four evenings
during the Inverse testing period. The Company believes that Prodigy has
corrected these software problems. In all other call failure rating categories
tested by Inverse during June, the Company's measurements were better than the
Inverse industry average. Investors should not place undue reliance on the
Inverse report as a measure of the Company's Network performance because it does
not measure and report on all the factors that may affect the quality of
Splitrock's services to Prodigy and Inverse's findings are based on tests
conducted on a sampling of only 42 POPs. Furthermore, the most recent Inverse
data reflect only two months of operations and there can be no assurance that
the Company will be able to sustain such a level of Network performance.
 
ESTABLISHMENT AND MAINTENANCE OF TRANSMISSION SERVICES AND PEERING RELATIONSHIPS
 
     The Company's success will depend upon its ability to complete the Phase II
Expansion and develop adequate support systems and services at an acceptable
cost. In order to complete the Phase II Expansion and continue operating the
existing POPs, the Company has entered into and will continue to enter into
agreements with various providers of infrastructure capacity.
 
     The Company currently maintains transmission services agreements primarily
with WorldCom Communications, Inc. ("WorldCom") for long distance and with
competitive local exchange carriers ("CLECs") and various regional Bell
operating companies ("RBOCs") for local connections. In the future, the Company
will be required to negotiate new transmission services agreements, or
renegotiate existing transmission services agreements, as the Company expands
the Network. There can be no assurance that the Company will successfully
negotiate or renegotiate such agreements. The failure to negotiate or
renegotiate required transmission services agreements could have a material
adverse effect on the Company's financial condition and results of operations.
See "Business -- Splitrock's Network -- Transmission Services."
 
     The Company has established peering arrangements with several ISPs and
intends to negotiate further agreements. The establishment and maintenance of
peering relationships with other network service providers is necessary in order
to exchange traffic with other network service providers without having to pay
transit costs. The basis on which network service providers make peering
available or impose settlement charges is
 
                                       22
<PAGE>   24
 
evolving as the provision of Internet access and related services has expanded
and the dominance of a small group of national network service providers has
driven corporate peering policies. Recently, companies that have previously
offered peering have cut back or eliminated peering relationships and are
establishing new, more restrictive criteria for peering. Furthermore, if
increasing requirements associated with maintaining peering with the major
national network service providers develop, the Company may have to comply with
those additional requirements in order to establish peering relationships.
Failure to maintain peering relationships or establish new ones, if necessary,
would cause the Company to incur additional operating expenditures which would
have a material adverse effect on the Company's business, financial condition
and results of operations. See "Business -- Splitrock's Network -- Peering."
 
LEVERAGE AND RESTRICTIONS IMPOSED BY INDEBTEDNESS
 
     The Company is highly leveraged. At March 31, 1998, on a pro forma basis
after giving effect to the offering of the Original Notes and the application of
the net proceeds therefrom, the Company would have had $279.2 million of total
indebtedness, representing approximately 93.4% of the Company's total
capitalization. See "Capitalization." In addition, the terms of the Notes permit
the Company to incur certain other indebtedness. There can be no assurance that
the Company will have sufficient cash flow to pay the interest expense or the
principal associated with the Notes or such additional indebtedness. See "Use of
Proceeds," "Selected Historical and Unaudited Pro Forma Financial Data,"
"Capitalization," and "Description of the Notes."
 
     The historical earnings of the Company were insufficient to cover its fixed
charges for the period from inception (March 5, 1997) to December 31, 1997 and
the three months ended March 31, 1998 by approximately $10.1 million and $3.7
million, respectively. On a pro forma basis after giving effect to the offering
of the Original Notes and the application of the net proceeds therefrom, the
earnings of the Company would have been insufficient to cover its fixed charges
for the period from inception (March 5, 1997) to December 31, 1997 and the three
months ended March 31, 1998 by approximately $36.3 million and $11.5 million,
respectively. See "Selected Historical and Unaudited Pro Forma Financial Data."
 
     The degree to which the Company will be leveraged could have several
important consequences to the holders of the Notes, including, but not limited
to, the following: (i) a substantial portion of the Company's cash flow from
operations will be required to be dedicated to service the Company's
indebtedness, and the failure of the Company to generate sufficient cash flow to
service such indebtedness could result in a default under such indebtedness,
including under the Notes; (ii) the Company's ability to obtain additional
financing in the future for working capital, capital expenditures, acquisitions
or for other purposes may be impaired; (iii) the Company's flexibility to
expand, make capital expenditures and respond to changes in the industry and
economic conditions may be limited; (iv) the Indenture will contain, and future
agreements relating to the Company's indebtedness (including any credit
facilities, to the extent permitted by the Indenture) may contain, numerous
financial and other restrictive covenants, including, among other things,
limitations on the ability of the Company to incur additional indebtedness, to
create liens and other encumbrances, to make certain payments and investments,
to pay dividends, to sell or otherwise dispose of assets or to merge or
consolidate with another entity, the failure to comply with which may result in
an event of default, which, if not cured or waived, could have a material
adverse effect on the Company; and (v) the Company will be more leveraged than
certain of its competitors, which might place the Company at a competitive
disadvantage. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
     The Company's ability to meet its debt service obligations, to finance
planned capital expenditures, lease payments or acquisitions or to comply with
the covenants contained in the Indenture will depend upon the Company's future
performance, which will be subject to general economic conditions and to
financial, business, competitive, legislative, regulatory and other factors
affecting its operations, many of which are beyond the control of the Company.
There can be no assurance that the Company's business will be able to generate
cash flow at levels sufficient to satisfy its debt service and other
requirements. If in the future the Company is unable to generate sufficient cash
from its operations to make scheduled interest payments on the Notes, to pay the
Notes at maturity, or to meet other obligations and commitments, the Company may
be required to adopt one or more alternatives, such as refinancing or
restructuring its indebtedness, reducing or
                                       23
<PAGE>   25
 
delaying planned expansion, selling assets or seeking to raise additional debt
or equity. There can be no assurance that the Company will be able to implement
any of these alternatives on satisfactory terms or at all. In addition, the
terms of existing or future debt agreements, including the Indenture, may
prohibit the Company from adopting some of these alternatives. See "Description
of the Notes."
 
ASSET ENCUMBRANCE
 
     The Exchange Notes will be senior obligations of Splitrock ranking pari
passu in right of payment with all existing and future Senior Indebtedness of
Splitrock. The Exchange Notes will be unsecured except that the Trustee will
have a security interest in the Escrow Account for the benefit of holders of the
Exchange Notes. The Indenture will permit the Company to incur certain
indebtedness, including secured indebtedness. Holders of secured indebtedness of
the Company will have claims with respect to the assets constituting collateral
for such indebtedness that are prior to the claims of holders of Exchange Notes.
 
     In the event of a default on the Exchange Notes, or a bankruptcy,
liquidation or reorganization of the Company, assets securing indebtedness of
the Company and its subsidiaries other than the Exchange Notes will be available
to satisfy obligations with respect to the indebtedness secured thereby before
any payment therefrom could be made on the Exchange Notes. Accordingly, the
Exchange Notes will be effectively subordinated to claims of secured creditors
of the Company to the extent of such pledged collateral. At March 31, 1998,
after giving pro forma effect to the offering of the Original Notes and the
application of the net proceeds therefrom, the Company would have had $21.1
million of secured indebtedness outstanding. See "Description of the Notes,"
"Selected Historical and Unaudited Pro Forma Financial Data," "Description of
Certain Indebtedness" and the Company's historical financial statements and
notes thereto included elsewhere in this Prospectus.
 
ABILITY TO MANAGE GROWTH
 
     To date, the Company's operations have been limited to one primary customer
and rapid growth may place a significant strain on the Company's Network and
management, administrative, operational and financial resources. The Company's
ability to manage its growth successfully will require the Company to further
enhance its operational, management, administrative, financial and information
systems and controls. There can be no assurance that the Company will have the
resources available to successfully enhance such systems and controls.
 
     Since June 1997, the Company has recruited and hired key members of
management in the areas of operations and administration. As a result, the key
members of the Company's management team have worked together for only a short
time. See "Management." Currently, the Company has limited personnel. In
accordance with the Company's growth strategy, it is seeking to hire additional
sales, marketing, administrative, operating and technical personnel. See
"Business -- Employees." Successful implementation of the Company's strategy
will depend on its ability to attract and retain such employees. The process of
locating, training and successfully integrating qualified personnel into the
Company's operations is often lengthy and expensive, and as a result of the
recent growth in the industry, the Company has experienced significant
competition in the attraction and retention of personnel that possess the skill
sets that the Company is seeking. There can be no assurance that the Company
will be successful in attracting, integrating and retaining such personnel. The
loss of the services of key personnel, or the inability to attract additional
qualified personnel, could have a material adverse effect on the Company's
results of operations, product development efforts, ability to attract customers
and ability to expand the Network.
 
     In addition, as the Company increases its service offerings and number of
customers, there will be additional demands on the Company's customer support,
sales, marketing and administrative resources and personnel as well as on the
Splitrock Network infrastructure. While the Company's Network is operational, it
has experienced significant recent interruptions and failures and has not been
tested under circumstances consistent with the more significant volume of
activity anticipated as the Company grows its business and continues to migrate
Prodigy traffic from the Legacy Network and the IBM Global Services Network to
the Splitrock Network. See "-- Difficulties in Expanding and Operating the
Splitrock Network" and "-- Reliance
 
                                       24
<PAGE>   26
 
on Prodigy; Recent Discussions with Prodigy." The Company's inability to
effectively manage its growth could have a material adverse effect on the
Company.
 
DEVELOPMENT OF EFFECTIVE PROCESSES AND SYSTEMS
 
     Sophisticated processes and systems are vital to the Company's growth and
its ability to monitor costs, bill customers, record and manage customer orders
and record taxes due. The Company utilizes information management, equipment
monitoring, tracking and other software systems provided by third party vendors
and intends to implement a billing system based on third party software late in
1998. As the Company's strategy provides for growth in the number and volume of
products and services offered by the Company, such systems will be required to
expand with and adapt to the Company's growth. Failure of third party vendors to
deliver proposed products and services in a timely and effective manner and at
acceptable costs, failure of the Company to adequately identify all of its
information and processing needs, failure of the Company's processing or
information systems or failure of the Company to upgrade systems as necessary
would have a material adverse effect on the ability of the Company to implement
its strategy and on its financial condition and results of operations.
 
COMPETITION
 
     The industry in which the Company competes is extremely competitive. The
Company expects that competition will continue to intensify as customers seek
additional capacity to satisfy continued growth of the Internet industry. In
addition, numerous competitors, including major telecommunications carriers, are
rapidly expanding their network capabilities. The Company believes that the
primary competitive factors for the provision of network services are quality of
service, network coverage, reliability, price, and product innovation.
Management believes it can compete effectively on these factors based on the
design of the Splitrock Network and industry experience at top management
levels, although there can be no assurance in this regard.
 
     The Company's current and prospective competitors generally may be divided
into two groups: (i) companies that provide Internet access services to ISPs
with both residential and small business customers, including Verio Inc.
("Verio"), Concentric Network Corporation ("Concentric"), PSINet Inc. ("PSINet")
and NETCOM On-Line Communications Services, Inc. ("Netcom") and (ii) companies
that provide Internet access (including Internet dial access and transit), VPN
and other value added services to medium and large business customers, including
UUNet Technologies, Inc., a subsidiary of WorldCom ("UUNet"), GTE
Internetworking (formerly Bolt, Beranek & Newman, Inc. ("BBN")) and DIGEX, a
subsidiary of Intermedia Communications Inc. ("DIGEX"), as well as most of the
major long distance companies. Many of these competitors, in addition to their
substantially greater market presence and financial, technical and personnel
resources, also have large existing commercial customer bases. Furthermore, many
of these competitors have the ability to bundle Internet access and VPN services
with other services such as Web browsing or, in the case of long distance
companies, telephony. Such bundling of services may have a material adverse
effect on the Company's ability to compete effectively and thus could have an
adverse effect on the Company's business, financial condition and results of
operations.
 
     The Company believes that significant new competitors will enter the
network services market. The Company is aware that other companies, including
IXC Communications Inc. ("IXC Comm.") and Level 3 Communications Inc. ("Level
3"), are in the process of building or expanding networks that will have the
ability to provide services comparable to those of the Company. In addition,
many of the Company's competitors have the financial and operational resources
to construct networks similar to the Splitrock Network. For example, Sprint
Communications Corp. ("Sprint") recently announced that it is in the process of
designing a network which will contain ATM switches at every core, hub and
remote site. There can be no assurance that the Company will be able to compete
effectively with such companies.
 
     Recent reforms in the federal regulation of the telecommunications industry
have also created greater opportunities for local exchange carriers ("LECs"),
including the RBOCs, to enter the Internet network services market and therefore
compete with the Company. Such increased competition could have a material
adverse effect on the Company. In order to address the Internet network service
requirements of the current
 
                                       25
<PAGE>   27
 
business customers of long distance and local carriers, the Company believes
that there is a trend toward horizontal integration through acquisitions of,
joint ventures with, and the wholesale purchase of connectivity from, ISPs. The
WorldCom/MFS Communications Company, Inc. ("MFS")/UUNet consolidation (as well
as the pending WorldCom/MCI Communications Corporation ("MCI") merger), the
Netcom/ICG Communications Inc. merger, the Intermedia Communications Inc.
("Intermedia")/DIGEX merger and the GTE Corporation's ("GTE") acquisition of BBN
are indicative of this trend. Such consolidations may result in the Company
competing with larger companies with greater resources to devote to the
development of new competitive products and services and the marketing of
existing competitive products and services.
 
     As a result of increased competition and integration in the industry, the
Company could encounter significant pricing pressure, which in turn could result
in significantly lower average selling prices of the Company's services. There
can be no assurance that the Company will be able to offset the effects of any
such lower prices with an increase in the number of its customers, growth in
sales to its customers base, higher revenue from enhanced services, cost
reductions or otherwise. In addition, the Company believes that the Internet
access and related services industry is likely to undergo further consolidation
in the near future, which could result in increased price and other competition
in these industries and, potentially, other portions of the industry, including
the market for VPN services. Increased price or other competition could have a
material adverse effect on the Company's business, financial condition and
results of operations. There can be no assurance that the Company will have the
financial resources, technical expertise or marketing and support capabilities
to continue to compete successfully.
 
DEPENDENCE ON SUPPLIERS
 
     The Company is dependent on third parties for key components of its network
infrastructure, including for leased lines, transmission services and networking
equipment, such as routers, switches and modems. The quantities and quality of
such networking equipment required by the Company are available only from
limited sources. The Company currently utilizes Lucent for ATM switching
products, including the Lucent LDR200 switch, Bay Networks, Inc. ("Bay
Networks") for its Internet dial access platform, Cisco Systems, Inc. ("Cisco")
for routers and Sun Microsystems, Inc. ("Sun") for servers. The Company also
depends upon a variety of LECs and interexchange carriers ("IXCs") to provide
telecommunication services, including leased line and collocation facilities.
 
     The Company currently has limited alternative suppliers for many of the
products or services it employs in its Network. In particular, Lucent is the
sole producer of the LDR200 switch, which the Company believes is a key
component of the Network. The Company has entered into a Purchase Agreement with
Yurie (which was acquired by Lucent in May 1998) pursuant to which the Company
agreed to purchase and Yurie agreed to provide a minimum of $20.0 million of
Yurie equipment and related products prior to January 1, 1999. As of July 15,
1998 the Company had purchased $11.0 million of equipment and products under
this agreement. Should the Company require additional Lucent LDR200 switches
beyond the quantity covered by the agreement (which the Company does not expect
to be the case), there can be no assurance that the Company will be able to
acquire them on acceptable terms, or at all. See "Business -- Suppliers." In
addition, expansion of network infrastructures by the Company and others is
placing, and will continue to place, a significant demand on the Company's other
suppliers, some of which have limited resources and production capacity. Certain
of the Company's suppliers, in turn, rely on sole or limited sources of supply
of components included in their products. These constraints may limit such
suppliers' ability to deliver products of the quality or within the time frame
demanded by the Company. The Company has experienced significant service
interruptions caused, in part, by faulty modem software code provided by one of
its suppliers. See "-- Reliance on Prodigy; Recent Discussions with Prodigy."
 
     The Company is also dependent upon third party suppliers for its data
communications facilities and capacity. Certain of these suppliers are or may
become competitors of the Company, and such suppliers are not subject to any
contractual restrictions upon their ability to compete with the Company. The
Company currently uses WorldCom for the majority of its long distance
connections and backbone long distance transmission facilities. In addition, the
Company obtains bandwidth capacity under leased line connection agreements with
LECs, including RBOCs, or is provided telecommunications services and leased
physical
                                       26
<PAGE>   28
 
space under local access/collocation agreements with various CLECs, such as
Focal Communications Corp. ("Focal"), Intermedia, Brooks Fiber Communications
and others. Since its inception, the Company has actively pursued agreements
with additional CLECs in an effort to establish relationships with a variety of
telecommunication providers and thereby reduce the cost of leased connectivity.
There can be no assurance that the Company will be able to continue to obtain
services from such suppliers on the scale and within the time frames required by
the Company at commercially reasonable cost, or at all. See
"Business -- Splitrock's Network -- Transmission Services." Any difficulties in
receiving adequate equipment, services or additional capacity on a timely basis
could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
     The Company has an agreement with IBM to use the IBM Global Services
Network to cover market areas that are neither served by the Splitrock Network
nor the Legacy Network. These POPs currently account for approximately 30% of
all Prodigy-related traffic. The terms of the agreement provide that either
party may, upon 60 days prior notice, terminate its respective obligations under
the contract for the remaining POP sites. In addition, under the terms of the
agreement with IBM services at certain of the POPs in the IBM Global Services
Network are scheduled to be discontinued on September 30, 1998. These POPs
currently represent less than 2% of the Company's Prodigy-related traffic. As
part of the Phase II Expansion, the Company plans to deploy POPs to those
locations. The Company has also formulated contingency plans, including
providing toll free Internet dial access to users in these areas, should the
Company be unable to timely deploy POPs in those areas or IBM be unwilling to
continue to provide service to those POPs after September 30, 1998. The
inability to provide coverage to those cities terminated on September 30, 1998
or any termination of IBM's other obligations under the contract could have a
material adverse effect on the Company's relationship with Prodigy, and,
consequently, the Company's business, financial condition and results of
operations.
 
     As part of the Company's strategy to replace remaining POPs covered by the
IBM Global Services Network and to complete the expansion of the Splitrock
Network, the Company will rely significantly upon third parties to provide
equipment and services and to deploy the remainder of the Splitrock Network. The
Company has an agreement with Ericsson under which Ericsson will provide certain
equipment and services for, and deploy, 99 additional POP sites (the "Ericsson
Agreement"). In April 1998, Ericsson provided the Company with a $5.0 million
credit facility to be used to pay amounts due under the Ericsson Agreement. All
amounts drawn under the facility were repaid upon consummation of the Unit
Offering. The Company is in negotiations with Ericsson for the deployment of the
additional 231 POPs needed to complete the Phase II Expansion. The Company
expects that such negotiations will lead to an agreement on similar terms and
conditions as the Ericsson Agreement. There can be no assurance that the Company
and Ericsson will come to an agreement on the deployment of the remaining 231
POPs required to complete the Network's expansion. Should the Company and
Ericsson fail to reach such an agreement, there can be no assurance that the
Company will be able to secure an alternative vendor to complete the Network's
expansion. The inability of Ericsson to complete its obligations under the
Ericsson Agreement or the failure of the Company to reach an agreement for the
deployment of additional POPs would have a material adverse effect on the
Company's business, results of operations and financial condition. See
"Business -- Suppliers" and "Description of Certain Indebtedness."
 
     The Company also engages third party vendors for routine maintenance,
on-call repair and certain related services. In addition to nine employees and
six individual contractors designated, trained and engaged by the Company as
field operation personnel, the Company has an agreement with IBM designed to
provide additional on-call field support personnel for maintenance, part
replacement and repairs for the Legacy Network until that network is
substantially decommissioned. In addition, during and following the Phase I
Buildout, WilTel has performed on-call services for replacement parts,
maintenance and repair services for the Splitrock Network. The agreement with
WilTel will expire on September 30, 1998. The Company is currently evaluating
and negotiating maintenance service proposals that are designed to replace the
existing agreements with IBM and WilTel and expand as the network infrastructure
grows. There can be no assurance that the Company will be able to enter into a
replacement maintenance agreement on acceptable terms, or at all. See
"Business -- Suppliers."
 
                                       27
<PAGE>   29
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company's business is managed by key executive officers, particularly
Mr. Kwok L. Li, Chairman of the Board and Chief Technical Officer, and Mr.
William R. Wilson, President and Chief Executive Officer. In addition, the
Company is currently in the process of recruiting additional key personnel,
including a Chief Operating Officer. The loss of one or more members of senior
management or the failure to recruit such personnel in the future could
significantly impede attainment of the Company's financial objectives. See "
Ability to Manage Growth." The Company does not currently maintain key man life
insurance on the life of any of its officers or employees but intends to acquire
such insurance for Mr. Li and Mr. Wilson in the near future.
 
CHANGE OF CONTROL
 
     The Indenture provides that upon the occurrence of a Change of Control each
holder of Notes will have the right to require the Company to repurchase all or
any part of such holder's Notes at a price in cash equal to 101% of the
aggregate principal amount thereof plus accrued and unpaid interest and
liquidated damages, if any, to the date of repurchase. The Indenture allows the
Company to incur certain indebtedness, including Senior Indebtedness. The terms
of such indebtedness may prohibit the repurchase of the Notes by the Company in
the event of a Change of Control, unless and until such time as it is repaid in
full. In such case, the Company, in order to repurchase the Notes, would need to
obtain the consent of the requisite lenders under such indebtedness or to repay
such indebtedness in full. The Company's failure to repurchase the Notes would
result in a default under the Indenture. The inability to repay any future
indebtedness, if accelerated, would also constitute an event of default under
the Indenture. There can be no assurance that the Company will have the
financial resources necessary to repurchase the Notes or any other indebtedness
upon a Change of Control. See "Description of the Notes -- Change of Control."
 
RISKS ASSOCIATED WITH STRATEGIC ALLIANCES AND ACQUISITIONS
 
     The Company intends to evaluate strategic alliances and acquisitions both
domestically and internationally as they present themselves. The Company
believes that an attractive strategic alliance or acquisition candidate should
provide additional traffic over the Network, service enabling technology, or
management or employee expertise. Any future strategic alliances or acquisitions
which the Company pursues would be accompanied by the risks commonly encountered
in strategic alliances with or acquisitions of companies. Such risks include,
among other things, the difficulty of integrating the operations and personnel
of the companies, the potential disruption of the Company's ongoing business,
the inability of management to maximize the financial and strategic position of
the Company by the successful incorporation of licensed or acquired technology
and rights into the Company's service offerings, the maintenance of uniform
standards, controls, procedures and policies and the impairment of relationships
with employees and customers as a result of changes in management. Any
international alliance or acquisition would be accompanied by the additional
risks of doing business abroad, including unexpected changes in the regulatory
environments, export controls, tariffs, fluctuations in currency exchange rates
and potentially adverse tax consequences. There can be no assurance that the
Company would be successful in overcoming these risks or any other problems
encountered in connection with such strategic alliances or acquisitions. In
connection with any strategic alliance or acquisition, the Company could incur
substantial expenses, including the expenses of integrating the business of the
strategic alliance or the acquired company with the Company's business. Such
expenses, in addition to the financial impact of such strategic alliances or
acquisitions, could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
CONTROL BY PRINCIPAL STOCKHOLDERS AND MANAGEMENT; TRANSACTIONS WITH RELATED
PARTIES
 
     Mr. Kwok L. Li, one of the founders and Chairman of the Board of the
Company, and Linsang Partners, LLC ("Linsang"), a company controlled by Mr. Li,
collectively own approximately 50.1% of the Company's outstanding shares. In
addition, William R. Wilson, the other founder and the President and Chief
Executive Officer of the Company, owns approximately 21.8% of the Company's
outstanding shares. As a result of this direct and indirect ownership, Mr. Li,
individually, and Mr. Li and Mr. Wilson, collectively, are able to elect
                                       28
<PAGE>   30
 
the entire Board of Directors of the Company, to direct the affairs of the
Company, to appoint new management and to approve any action requiring the
approval of the holders of the Company's capital stock, including the adoption
of amendments to the Company's certificate of incorporation and approval of
mergers or sales of substantially all of the Company's assets. There can be no
assurance that the interests of Mr. Li and Mr. Wilson will not conflict with the
interests of the holders of the Notes. See "Principal Stockholders."
 
     Certain of the directors of the Company also serve as directors and/or
officers of other companies with which the Company conducts business and,
consequently, there exists the possibility that such directors will have a
conflict of interest. Until its sale to Lucent, Mr. Li was Director, Vice
Chairman, Chief Technology Officer and owner of 12.4% of the Common stock of
Yurie, one of the Company's principal suppliers. In connection with the sale of
Yurie to Lucent, Linsang has agreed to make the services of Mr. Li available to
Lucent to provide technical guidance for both the Lucent LDR200 and Lucent's
entire line of other ATM switches. The agreement has a term of three years and
terminates on May 29, 2001. Mr. Li has been named Chief Technical Officer of the
Carrier Network division of Lucent and has agreed to not participate in
designing, developing, producing, manufacturing or marketing multi-service
access equipment other than for Lucent. See "-- Dependence on Suppliers".
Furthermore, Mr. Samer Salameh is President and Chief Executive Officer of
Prodigy and is a member of the Company's Board of Directors. In addition,
certain stockholders may have conflicting interests. Orient Star, a wholly owned
subsidiary of Carso, owns 20.0 million shares, or 25.7%, of the outstanding
shares of Common Stock of the Company and an option, exercisable through
September 18, 1998, to subscribe for an additional 5.0 million shares which, if
exercised, would result in Orient Star holding approximately 30.2% of the Common
Stock of the Company. The Company expects that this option will be exercised
although no assurance can be given in this regard. Carso is a controlling
stockholder of Prodigy and a significant stockholder of Telmex.
 
     Any decision made by directors is required by law to be made in accordance
with their duties and obligations to deal fairly and in good faith with a view
to the best interests of the Company and its shareholders. Directors may owe
similar duties to the other companies for which they serve as directors or
officers. Due in part to the nature of the potential conflicts presented on an
ongoing basis by certain of the Company's suppliers, customers and others, there
can be no assurance that the directors involved in such a conflict will act in
the best interests of the Company. See "Management -- Certain Relationships and
Related Transactions" and "Description of the Notes -- Certain Covenants
Limitation on Transactions with Affiliates."
 
RISKS OF TECHNOLOGY TRENDS AND EVOLVING INDUSTRY STANDARDS
 
     The markets for Internet access, transit services, VPNs and related
services provided by the Company are relatively new and characterized by rapidly
changing technology, evolving industry standards, changes in customer needs and
frequent new product and service introductions. The Company's future success
will depend, in part, on its ability to effectively use leading technologies, to
continue to develop its technical expertise, to enhance its current services, to
develop new products and services that meet changing customer needs, and to
influence and respond to emerging industry standards and other technological
changes on a timely and cost-effective basis. There can be no assurance that the
Company will be successful in effectively using new technologies, developing new
services and technical expertise or enhancing its current services on a timely
basis or that such new technologies or enhancements will achieve market
acceptance. The Company believes that its ability to compete successfully is
also dependent upon the continued compatibility of its services with products
and architectures offered by various vendors. There can be no assurance that the
Company will be able to effectively address the compatibility issues raised by
technological changes or new industry standards. In addition, there can be no
assurance that services or technologies developed by others will not render the
services or technology of the Company or its vendors uncompetitive or obsolete.
 
     In addition, issues concerning the commercial use of the Internet and other
services remain unresolved and may impact the growth of Internet use, especially
in the business market targeted by the Company. Despite growing interest in the
many commercial uses of the Internet, many businesses have been deterred from
purchasing Internet access services for a number of reasons, including, among
others, inconsistent quality of service, the lack of availability of
cost-effective, high-speed options, a limited number of local access points
                                       29
<PAGE>   31
 
for corporate users, inability to integrate business applications on the
Internet, the need to deal with multiple and frequently incompatible vendors,
inadequate protection of the confidentiality of stored data and information
moving across the Internet, and a lack of tools to simplify Internet access and
use. In particular, there is a perceived lack of security of commercial data,
such as credit card numbers, that has significantly impeded commercial
exploitation of the Internet to date, and there can be no assurance that
encryption or other technologies will be developed that satisfactorily address
these security concerns. Capacity constraints caused by growth in the use of the
Internet may, unless resolved, also impede further development of the Internet
to the extent that users experience delays, transmission errors and other
difficulties. The failure of the Internet industry to address these concerns and
introduce viable solutions could limit the growth of the Internet and other
telecommunications services. Any such failure would have a material adverse
effect on the Company's ability to rapidly grow its business and attain its
financial objectives.
 
NETWORK SECURITY RISKS
 
     Despite the implementation of network security measures by the Company,
such as limiting physical and network access to its equipment, its
infrastructure is potentially vulnerable to computer viruses, break-ins and
similar disruptive problems caused by others. Computer viruses, break-ins or
other problems caused by third parties could lead to interruptions, delays or
cessation in service to the Company's customers. Furthermore, inappropriate use
of the Internet by third parties could also potentially jeopardize the security
of confidential information stored in the computer systems of the Company's
customers, which may deter potential customers and adversely affect existing
customer relationships. Security problems represent an ongoing threat to public
and private data networks. Addressing problems caused by computer viruses,
break-ins or other problems caused by third parties could have a material
adverse effect on the Company.
 
     The security measures employed by the Company cannot assure complete
protection from computer viruses, break-ins and other disruptive problems. The
occurrence of such problems may result in claims against or liability on the
part of the Company. Such claims, regardless of their ultimate outcome, could
result in costly litigation and could have a material adverse effect on the
Company's business or reputation or on its ability to attract and retain
customers for its services.
 
RISK OF SYSTEM FAILURE; INSURANCE
 
     The success of the Company is dependent upon its ability to protect its
network infrastructure against damage from fire, earthquakes, floods, power
loss, telecommunications failures and similar events. Despite precautions taken
by and planned by the Company, the occurrence of a natural disaster or other
unanticipated problems at one of the Company's NOCs or at a number of the
Company's core sites, hub sites or remote access sites could cause significant
interruptions in the services provided by the Company. Additionally, failure of
the Company's telecommunications providers to provide the communications
capacity required by the Company as a result of natural disaster, operational
disruption or for any other reason could cause significant interruptions in the
services provided by the Company. While the Company believes it has insurance
adequate to cover such risks, the occurrence of a significant loss not fully
covered by insurance could have a material adverse effect on the Company. In
addition, there can be no assurance that the Company will be able to maintain
adequate insurance coverage at rates it believes reasonable.
 
REGULATORY MATTERS; POTENTIAL LIABILITY FOR INFORMATION DISSEMINATED OVER THE
INTERNET
 
     Although the Company is not currently subject to direct regulation by the
Federal Communications Commission ("FCC") or any other federal or state agency,
it operates in a highly regulated industry and therefore changes in the
regulatory environment relating to Internet services and traditional
telecommunications services, including regulatory changes which directly or
indirectly affect telecommunications costs or increase the likelihood or scope
of competition from RBOCs or other telecommunication companies, could have a
material adverse effect on the Company's financial position or results of
operations, including by affecting the prices at which the Company offers its
services or imposing regulatory compliance and other costs on the Company. There
can be no assurance that future service offerings of the Company will not be
subject to regulation or that the current regulatory environment will not evolve
in ways which impose
                                       30
<PAGE>   32
 
requirements on the Company or its customers that would materially adversely
affect the Company. Various existing federal and state regulations are currently
the subject of judicial proceedings, legislative hearings and administrative
proposals which could change, in varying degrees, the manner in which the
industry operates. For example, the FCC is considering whether Internet related
service providers should be required to pay into Universal Service subsidy
pools. The imposition of such regulatory charges or similar regulatory
constraints would affect the Company's costs of serving its customers and could
have a material adverse effect on the Company's business and results of
operations. Furthermore, the FCC has indicated that it may consider regulating
ISPs, which could have a material adverse effect on the Company. In addition,
Internet telephony may become subject to some form of regulation in the future.
See "Business -- Regulation".
 
     The law in the United States relating to the liability of ISPs and
providers of transmission capacity for information carried on, disseminated
through, or hosted on their systems is currently unsettled. The
Telecommunications Act of 1996 (the "Communications Act") and statutes enacted,
or under consideration in some states, impose civil and criminal liability upon
ISPs, or providers of transmission capacity to ISPs, for the transmission or
dissemination of certain types of information and materials. The imposition of
such liability may require the Company to implement measures to reduce its
exposure to such liability, which may require the expenditure of substantial
resources. Regulations, litigation, or legislation could affect the demand for
the Company's services.
 
DISCRETIONARY AUTHORITY OVER USE OF NET PROCEEDS
 
     Management will retain a significant amount of discretion over the
application of the net proceeds of the Offering (other than amounts required to
be deposited into escrow). Because of the number and variability of factors that
determine the Company's use of the net proceeds of the Offering, there can be no
assurance that such applications will not vary substantially from the Company's
current intentions. Pending utilization, the Company intends to invest the net
proceeds of the Offering in investment grade and U.S. government securities.
 
BANKRUPTCY RISKS RELATED TO ESCROW ACCOUNT
 
     The right of the Trustee under the Indenture and the Escrow and
Disbursement Agreement (as defined) to foreclose upon and sell Escrow Collateral
(as defined) upon the occurrence of an Event of Default on the Notes is likely
to be significantly impaired by applicable bankruptcy law if a bankruptcy or
reorganization case were to be commenced by or against the Company. Under
applicable bankruptcy law, secured creditors such as the holders of the Notes
are prohibited from foreclosing upon or disposing of a debtor's property without
prior bankruptcy court approval. See "Description of Notes -- Disbursement of
Funds; Escrow Account."
 
FRAUDULENT CONVEYANCE; PREFERENTIAL TRANSFER
 
     If, in a bankruptcy or reorganization case or a lawsuit by or on behalf of
unpaid creditors of the Company, a court were to find that, at the time the
Company incurred indebtedness under the Notes, (i) the Company incurred such
indebtedness with the intent of hindering, delaying or defrauding current or
future creditors or (ii)(a) the Company received less than reasonably equivalent
value or fair consideration for incurring such indebtedness and (b) the Company
(1) was insolvent or was rendered insolvent by reason of such incurrence, (2)
was engaged, or about to engage, in a business or transaction for which its
assets constituted unreasonably small capital, (3) intended to incur, or
believed that it would incur, debts beyond its ability to pay such debts as they
matured (as all of the foregoing terms are defined in or interpreted under the
relevant fraudulent transfer or conveyance statutes) or (4) was a defendant in
an action for money damages, or had a judgment for money damages docketed
against it (if, in either case, after final judgment, the judgment is
unsatisfied), then such court could avoid or subordinate the Company's
obligations under the Notes to presently existing and future indebtedness of the
Company and take other actions detrimental to the holders of the Notes.
 
     For purposes of the foregoing, the measure of insolvency varies depending
upon the law of the jurisdiction which is being applied. Generally, however, the
Company would be considered to have been insolvent at the time the Notes were
issued if the sum of its debts was, at that time, greater than the sum of the
value of all of
 
                                       31
<PAGE>   33
 
its property at a fair valuation, or if the then fair saleable value of its
assets was less than the amount that was then required to pay its probable
liability on its existing debts as they became absolute and matured. There can
be no assurance as to what standard a court would apply in order to determine
whether the Company was insolvent as of the date the Notes were issued, or that,
regardless of the method of valuation, a court would not determine that the
Company was insolvent on that date, or that, regardless of whether the Company
was insolvent on the date the Notes were issued, that the issuance constituted a
fraudulent transfer for the grounds summarized above.
 
     Additionally, under federal bankruptcy law or applicable state insolvency
law, if certain bankruptcy or insolvency proceedings were initiated by or
against the Company within 90 days after any payment by the Company with respect
to the Notes or if the Company anticipated becoming insolvent at the time of
such payment or incurrence, all or a portion of such payment could be avoided as
a preferential transfer and the recipient of such payment could be required to
return such payment.
 
ABSENCE OF PUBLIC MARKET
 
     Before the Exchange Offer, there has not been any public market for the
Original Notes. The Original Notes have not been registered under the Securities
Act and are subject to restrictions on transferability to the extent that they
are not exchanged for Exchange Notes by holders who are entitled to participate
in the Exchange Offer. The Exchange Notes will constitute a new issue of
securities with no established trading market. The Company does not intend to
list the Exchange Notes on any national securities exchange or to seek approval
for quotation through any automated quotation system. The Initial Purchaser of
the Original Notes currently makes a market in the Notes, but is not obligated
to do so and may discontinue such market making at any time. In addition, such
market making activity will be subject to the limits imposed by the Securities
Act and the Exchange Act and may be limited during the Exchange Offer.
Accordingly, no assurance can be given that an active public or other market
will develop for the Exchange Notes or as to the liquidity of the trading market
for the Exchange Notes. If a trading market does not develop or is not
maintained, holders of the Exchange Notes may experience difficulty in reselling
the Exchange Notes or may be unable to sell them at all. If a market for the
Exchange Notes develops, any such market may be discontinued at any time.
 
     If a public trading market develops for the Exchange Notes, future trading
prices of such securities will depend on many factors, including, among other
things, prevailing interest rates, the Company's results of operations and the
market for similar securities. Depending on prevailing interest rates, the
market for similar securities and other factors, including the financial
condition of the Company, the Exchange Notes may trade at a discount from their
principal amount. Historically, the market for securities similar to the
Exchange Notes, including non-investment grade debt, has been subject to
disruptions that have caused substantial volatility in the prices of such
securities. There can be no assurance that any market for the Exchange Notes, if
such market develops, will not be subject to similar disruptions.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
     Holders of Original Notes who do not exchange their Notes for Exchange
Notes pursuant to the Exchange Offer will continue to be subject to the
restrictions on transfer of such Notes as set forth in the legend thereon and in
the Offering Memorandum, dated July 21, 1998, because the Original Notes were
issued pursuant to exemptions from, or in transactions not subject to, the
registration requirements of the Securities Act and applicable state securities
laws. In general, the Original Notes may not be offered or sold unless
registered under the Securities Act and applicable state securities laws, or
pursuant to an exemption therefrom, or in a transaction not subject to the
Securities Act and applicable state securities laws. The Company does not intend
to register the Original Notes under the Securities Act, and after consummation
of the Exchange Offer will not be obligated to do so except under limited
circumstances. To the extent Original Notes are tendered and accepted in the
Exchange Offer, the trading market for untendered and tendered but unaccepted
Original Notes could be adversely affected. See "The Exchange Offer."
 
                                       32
<PAGE>   34
 
EXCHANGE OFFER PROCEDURES
 
     The Exchange Notes will be issued in exchange for Original Notes only after
timely receipt by the Exchange Agent of such Original Notes, a properly
completed and duly executed Letter of Transmittal and all other required
documents. Therefore, holders of Original Notes desiring to tender such Original
Notes in exchange for Exchange Notes should allow sufficient time to ensure
timely delivery. Neither the Exchange Agent nor the Company is under any duty to
give notification of defects or irregularities with respect to tenders of
Original Notes for exchange. Original Notes that are not tendered or are
tendered but not accepted will, following consummation of the Exchange Offer,
continue to be subject to the existing restrictions upon transfer thereof. In
addition, any holder of Original Notes who tenders in the Exchange Offer for the
purpose of participating in a distribution of the Exchange Notes will be
required to comply with the registration and prospectus delivery requirements of
the Securities Act in connection with any resale transaction. Based on an
interpretation by the staff of the Commission set forth in no-action letters
issued to third parties, the Company believes that the Exchange Notes issued
pursuant to the Exchange Offer in exchange for Original Notes may be offered for
resale, resold or otherwise transferred by holders thereof (other than any such
holder which is an "affiliate" of the Company within the meaning of Rule 405
under the Securities Act) without compliance with the registration and
prospectus delivery provisions of the Securities Act, if such Exchange Notes are
acquired in the ordinary course of such holder's business, such holders have no
arrangement with any person to participate in the distribution of such Exchange
Notes and neither such holders nor any such other person is engaging in or
intends to engage in a distribution of such Exchange Notes. Any holder of
Original Notes who tenders in the Exchange Offer for the purpose of
participating in a distribution of the Exchange Notes may be deemed to have
received restricted securities and, if so, will be required to comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. Each broker-dealer that receives
Exchange Notes for its own account in exchange for Original Notes, where such
Original Notes were acquired by such broker-dealer as a result of market-making
activities or any other trading activities, must acknowledge that it will
deliver a prospectus in connection with any resale of such Exchange Notes. See
"Plan of Distribution" and "The Exchange Offer."
 
YEAR 2000
 
     The year-2000 issue (as defined) is the result of computer programs being
written using two digits, rather than four digits, to define the applicable
year. Programs that have time-sensitive software may recognize a date using "00"
as the year 1900 rather than the year 2000 (the "year-2000 issue"). This could
result in a major system failure or miscalculations, including an inability to
process transactions, send invoices or engage in similar normal business
activities. Due to its reliance on computer hardware and software, the Internet
and related service industries are highly susceptible to the year-2000 issue. If
the year-2000 issue should cause widespread problems across the Internet, usage
can be expected to decline dramatically. Such an event would have a material
adverse effect on the Company's financial condition and results of operations,
the nature and extent of which cannot reasonably be determined by the Company on
the basis of information currently available to it. The Company has not prepared
a contingency plan and does not expect to do so in light of the uncertainty of
the impact of year-2000 issues on the Internet as a whole and the Company's
anticipated schedule to be year-2000 compliant before the end of 1999.
 
     The Company is currently in the process of evaluating its operations and
both its information technology systems and its non-information technology
systems to determine its own vulnerability to the year-2000 issue. The Company
relies heavily on non-information technology systems in the conduct of its
operations and has determined that substantially all of such systems are
year-2000 compliant. Certain network-monitoring software, which is used by the
Company to monitor network equipment (POPs) on the Legacy Network, is not
year-2000 compliant, but as part of the Company's Phase II Expansion,
substantially all of the Legacy Network POPs are scheduled to be decommissioned
by the end of 1998 and such network-monitoring software will no longer be used
by the Company. With respect to the Company's database inventory software, used
to capture data about the network configuration, including location of equipment
and maintenance, the Company has purchased and is currently installing year-2000
compliant software to replace its existing software. Installation is scheduled
to be completed by the end of 1998, and the cost of such purchase and
 
                                       33
<PAGE>   35
 
installation is not material. The Company has also determined that certain other
of its software systems are not year-2000 compliant. The Company believes that,
with modifications and upgrades to such software, which are scheduled to occur
in the ordinary course of business, it will be fully year-2000 compliant by the
end of 1999. The Company is continuing its evaluation of the remaining areas
impacted by year-2000 issues, including Internet interfaces, facility matters
and equipment vendors, but does not expect to incur material costs in connection
with making its software year-2000 compliant. To date the Company has not
incurred material costs in ensuring year-2000 compliance.
 
     The Company is also dependent upon the ability of its customers to ensure
that their software and equipment is year-2000 compliant. The Company has
initiated formal communications with Prodigy to determine the extent to which
the Company is vulnerable to Prodigy's own year-2000 issues, if any. Prodigy has
informed the Company that Prodigy Classic may not be year-2000 compliant.
Prodigy is in the process of migrating users to Prodigy Internet, which is
year-2000 compliant, and plans to discontinue Prodigy Classic service by the end
of 1999. However, there can be no guarantee that Prodigy Classic or systems of
future customers on which the Company may rely will be timely converted, or that
a failure to convert, or a conversion that is incompatible with the Company's
systems, would not have a material adverse effect on the Company.
 
                                USE OF PROCEEDS
 
     The Company will not receive any cash proceeds from the issuance of the
Exchange Notes offered hereby. In consideration for issuing the Exchange Notes
as contemplated in this Prospectus, the Company will receive in exchange
Original Notes in like principal amount, the terms of which are substantially
identical to the Exchange Notes. The Original Notes surrendered in exchange for
Exchange Notes will be retired and cancelled and cannot be reissued.
Accordingly, issuance of the Exchange Notes will not result in any increase in
the outstanding indebtedness of the Company.

    This amount was refinanced in connection with the Unit Offering. In
    connection with such refinancing, such stockholder purchased $11.0 million
    of the Original Notes. After giving effect to such refinancing and the

                               THE EXCHANGE OFFER
 
EXCHANGE OFFER PURSUANT TO EXCHANGE AND REGISTRATION RIGHTS AGREEMENT
 
     The Original Notes were sold by the Company on July 24, 1998 (the "Issue
Date"). The Initial Purchaser purchased $261,000,000 in aggregate principal
amount of the Original Notes, of which $11.0 million in aggregate principal
amount of the Original Notes were sold to Linsang, an affiliate of the Company.
As a condition to the sale of the Original Notes, the Company and the Initial
Purchaser entered into the Exchange and Registration Rights Agreement on the
Issue Date. Pursuant to the Exchange and Registration Rights Agreement, the
Company agreed that, unless the Exchange Offer is not permitted by applicable
law or Commission policy, it would (i) file with the Commission a Registration
Statement under the Securities Act with respect to the Exchange Notes within 45
days after the Issue Date, (ii) use its reasonable best efforts to cause such
Registration Statement to become effective under the Securities Act within 105
days after the Issue Date and (iii) upon effectiveness of the Registration
Statement, commence the Exchange Offer, keep the Exchange Offer open for at
least 30 days (or a longer period if required by law) and deliver to the
Exchange Agent Exchange Notes in the same aggregate principal amount at maturity
as the Original Notes that were tendered by holders thereof pursuant to the
Exchange Offer. A copy of the Exchange and Registration Rights Agreement has
been filed as an exhibit to the Registration Statement of which this Prospectus
is a part. The Registration Statement of which this Prospectus is a part is
intended to satisfy certain of the Company's obligations under the Exchange and
Registration Rights Agreement.
 
     If (i) because of any change in law or applicable interpretations thereof
by the staff of the Commission, the Company is not permitted to effect the
Exchange Offer as contemplated hereby, (ii) any Original Notes validly tendered
pursuant to the Exchange Offer are not exchanged for Exchange Notes within 135
days after the Issue Date, (iii) the Initial Purchaser so requests with respect
to Original Notes not eligible to be exchanged for Exchange Notes in the
Exchange Offer, (iv) any applicable law or interpretations do not permit any
holder of Original Notes to participate in the Exchange Offer, (v) any holder of
Original Notes that participates in the Exchange Offer does not receive freely
transferable Exchange Notes in exchange for tendered Original Notes, or (vi) the
Company so elects, the Company has agreed to file with the Commission a shelf
registration statement (the "Shelf Registration Statement") to cover resales of
each Original Note that (i) has not been exchanged for a freely transferable
Exchange Note in the Exchange Offer; (ii) has not been effectively registered
under the Securities Act and disposed of in accordance with the Shelf
Registration Statement or (iii) has not been nor is eligible to be distributed
to the public pursuant to Rule 144 under the Securities Act or Rule 144(k) under
the Securities Act (each such Original Note being a "Restricted Note").
 
RESALE OF THE EXCHANGE NOTES
 
     With respect to the Exchange Notes, based upon an interpretation by the
staff of the Commission set forth in certain no-action letters issued to third
parties, the Company believes that a holder (other than (i) a broker-dealer who
purchases such Exchange Notes directly from the Company to resell pursuant to
Rule 144A or any other available exemption under the Securities Act or (ii) any
such holder which is an "affiliate" of the Company within the meaning of Rule
405 under the Securities Act) who exchanges the Original Notes for the Exchange
Notes in the ordinary course of business and who is not participating, does not
intend to participate, and has no arrangement with any person to participate, in
the distribution of the Exchange Notes, will be allowed to resell the Exchange
Notes to the public without further registration under the Securities Act and
without delivering to the purchasers of the Exchange Notes a prospectus that
satisfies the requirements of Section 10 of the Securities Act. However, if any
holder acquires the Exchange Notes in the Exchange Offer for the purposes of
distributing or participating in the distribution of the Exchange Notes or is a
broker-dealer, such holder cannot rely on the position of the staff of the
Commission enumerated in certain no-action letters issued to third parties and
must comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any resale transaction, unless an exemption
from registration is otherwise available. Each broker-dealer that receives
Exchange Notes for its own account in exchange for Original Notes, where such
Original Notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities, must acknowledge that it will deliver a
prospectus in
 
                                       36
<PAGE>   38
 
connection with any resale of such Exchange Notes. The Company has agreed to
make available a Prospectus meeting the requirements of the Securities Act to
any broker-dealer for use in connection with any resale of any such Exchange
Notes acquired as described below for such period as such broker-dealers must
comply with such requirements. A broker-dealer that delivers such a Prospectus
to purchasers in connection with such resales will be subject to certain of the
civil liability provisions under the Securities Act, and will be bound by the
Exchange and Registration Rights Agreement (including certain indemnification
rights and obligations). The Letter of Transmittal states that by so
acknowledging and by delivering a prospectus, a broker-dealer will not be deemed
to admit that it is an "underwriter" within the meaning of the Securities Act.
This Prospectus, as it may be amended or supplemented from time to time, may be
used by a broker-dealer in connection with resales of Exchange Notes received in
exchange for Original Notes where such Original Notes were acquired by such
broker-dealer as a result of market-making or other trading activities. Pursuant
to the Registration Rights Agreement, the Company has agreed to make this
Prospectus, as it may be amended or supplemented from time to time, available to
broker-dealers for us in connection with any resale for a period of 180 days
after the Expiration Date. See "Plan of Distribution."
 
TERMS OF THE EXCHANGE OFFER
 
     Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Company will accept any and all Original
Notes validly tendered and not withdrawn prior to the Expiration Date. The
Company will issue $1,000 principal amount of Exchange Notes in exchange for
each $1,000 principal amount of outstanding Original Notes surrendered pursuant
to the Exchange Offer. Notes may be tendered only in integral multiples of
$1,000.
 
     The form and terms of the Exchange Notes are the same as the form and terms
of the Original Notes except that (i) the exchange will be registered under the
Securities Act and hence the Exchange Notes will not bear legends restricting
their transfer and (ii) holders of the Exchange Notes will not be entitled to
the certain rights of holders of the Original Notes under the Exchange and
Registration Rights Agreement, which rights will terminate upon the consummation
of the Exchange Offer. The Exchange Notes will evidence the same debt as the
Original Notes (which they replace) and will be issued under, and be entitled to
the benefits of, the Indenture, which also authorized the issuance of the
Original Notes, such that all outstanding Notes will be treated as a single
class of debt securities under the Indenture.
 
     As of the date of this Prospectus, $250.0 million aggregate principal
amount of the Original Notes are outstanding and registered in the name of Cede
& Co., as nominee for The Depository Trust Company (the "Depositary"). In
addition, Original Notes in the aggregate principal amount of $11.0 million,
also outstanding and registered in the name of Cede & Co. (which are not
eligible to be exchanged under this Exchange Offer) are held by an affiliate of
the Company. Such $11.0 million of Original Notes will be exchanged for $11.0
million of Exchange Notes in a private offering and the Exchange Notes are
expected to be registered for resale under the Securities Act. Only a registered
holder of the Original Notes (or such holder's legal representative or
attorney-in-fact) as reflected on the records of the Trustee under the Indenture
may participate in the Exchange Offer. There will be no fixed record date for
determining registered holders of the Original Notes entitled to participate in
the Exchange Offer.
 
     Holders of the Original Notes do not have any appraisal or dissenter's
rights under the Indenture in connection with the Exchange Offer. The Company
intends to conduct the Exchange Offer in accordance with the provisions of the
Exchange and Registration Rights Agreement and the applicable requirements of
the Securities Act, the Exchange Act and the rules and regulations of the
Commission thereunder.
 
     The Company shall be deemed to have accepted validly tendered Original
Notes when, as and if the Company has given oral or written notice thereof to
the Exchange Agent. The Exchange Agent will act as agent for the tendering
holders of Original Notes for the purposes of receiving the Exchange Notes from
the Company.
 
     Holders who tender Original Notes in the Exchange Offer will not be
required to pay brokerage commissions or fees or, subject to the instructions in
the Letter of Transmittal, transfer taxes with respect to the exchange of Notes
pursuant to the Exchange Offer. The Company will pay all charges and expenses,
other
                                       37
<PAGE>   39
 
than certain applicable taxes described below, in connection with the Exchange
Offer. See " Fees and Expenses."
 
                                      37.1
<PAGE>   40
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
     The term "Expiration Date" shall mean 5:00 p.m., New York City time on
            , 1998 unless the Company, in its sole discretion, extends the
Exchange Offer to a date not later than             , 1998, in which case the
term "Expiration Date" shall mean the latest date and time to which the Exchange
Offer is extended.
 
     In order to extend the Exchange Offer, the Company will (i) notify the
Exchange Agent of any extension by oral or written notice, (ii) will mail to the
registered holders of Original Notes an announcement thereof, (iii) will issue a
press release or other public announcement which shall include disclosure of the
approximate number of Original Notes deposited to date, each prior to 9:00 a.m.,
New York City time, on the next business day after the previously scheduled
Expiration Date. Without limiting the manner in which the Company may choose to
make a public announcement of any delay, extension, amendment or termination of
the Exchange Offer, the Company shall have no obligation to publish, advertise
or otherwise communicate any such public announcement, other than by making a
timely release to an appropriate news agency.
 
     The Company reserves the right, in its sole discretion, (i) to delay
accepting any Original Notes, (ii) to extend the Exchange Offer, or (iii) if any
conditions set forth below under "-- Certain Conditions to the Exchange Offer"
shall not have been satisfied, to terminate the Exchange Offer by giving oral or
written notice of such delay, extension or termination to the Exchange Agent.
Any such delay in acceptance, extension, termination or amendment will be
followed as promptly as practicable by oral or written notice thereof to the
registered holders. If the Exchange Offer is amended in a manner determined by
the Company to constitute a material change, the Company will promptly disclose
such amendment by means of a prospectus supplement that will be distributed to
the registered holders of Original Notes, and the Company will extend the
Exchange Offer for a period of five to 10 business days, depending upon the
significance of the amendment and the manner of disclosure to such registered
holders, if the Exchange Offer would otherwise expire during such five to 10
business day period.
 
INTEREST ON THE EXCHANGE NOTES
 
     The Exchange Notes bear interest at a rate equal to 11 3/4% per annum.
Interest on the Exchange Notes is payable semi-annually on each January 15 and
July 15, commencing on January 15, 1999. Holders of Exchange Notes will receive
interest on January 15, 1999 from the date of initial issuance of the Original
Notes plus an amount equal to the interest accrued on the Original Notes.
Interest on the Original Notes accepted for exchange will cease to accrue upon
issuance of the Exchange Notes.
 
PROCEDURES FOR TENDERING
 
     Only a registered holder of Original Notes may tender such Original Notes
in the Exchange Offer. To tender in the Exchange Offer, a holder must complete,
sign and date the Letter of Transmittal, or facsimile thereof, have the
signatures thereon guaranteed if required by the Letter of Transmittal, and mail
or otherwise deliver such Letter of Transmittal or such facsimile to the
Exchange Agent at the address set forth below under "-- Exchange Agent" for
receipt prior to the Expiration Date. In addition, either (i) certificates for
such Original Notes must be received by the Exchange Agent along with the Letter
of Transmittal, or (ii) a timely confirmation of a book-entry transfer (a
"Book-Entry Confirmation") of such Original Notes, if such procedure is
available, into the Exchange Agent's account at the Depositary pursuant to the
procedure for book-entry transfer described below, must be received by the
Exchange Agent prior to the Expiration Date, or (iii) the holder must comply
with the guaranteed delivery procedures described below.
 
     The tender by a holder which is not withdrawn prior to the Expiration Date
will constitute an agreement between such holder and the Company in accordance
with the terms and subject to the conditions set forth herein and in the Letter
of Transmittal.
 
     THE METHOD OF DELIVERY OF ORIGINAL NOTES AND THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK
OF THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOM-
 
                                       38
<PAGE>   41
 
MENDED THAT HOLDERS USE AN OVERNIGHT OR HAND DELIVERY SERVICE, PROPERLY INSURED.
IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE
EXCHANGE AGENT BEFORE THE EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR ORIGINAL
NOTES SHOULD BE SENT TO THE COMPANY. HOLDERS MAY REQUEST THEIR RESPECTIVE
BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE
ABOVE TRANSACTIONS FOR SUCH HOLDERS.
 
     Any beneficial owner(s) of the Original Notes whose Original Notes are
registered in the name of a broker, dealer, commercial bank, trust company or
other nominee and who wishes to tender should contact the registered holder
promptly and instruct such registered holder to tender on such beneficial
owner's behalf. If such beneficial owner wishes to tender on such owner's own
behalf, such owner must, prior to completing and executing the Letter of
Transmittal and delivering such owner's Original Notes, either make appropriate
arrangements to register ownership of the Original Notes in such owner's name
(to the extent permitted by the Indenture) or obtain a properly completed bond
power from the registered holder. The transfer of registered ownership may take
considerable time.
 
     Signatures on a Letter of Transmittal or a notice of withdrawal described
below (see "-- Withdrawal of Tenders"), as the case may be, must be guaranteed
by an Eligible Institution (as defined below) unless the Original Notes tendered
pursuant thereto are tendered (i) by a registered holder who has not completed
the box entitled "Special Delivery Instructions" on the Letter of Transmittal or
(ii) for the account of an Eligible Institution. If signatures on a Letter of
Transmittal or a notice of withdrawal, as the case may be, are required to be
guaranteed, such guarantee must be made by a member firm of a registered
national securities exchange or of the National Association of Securities
Dealers, Inc., a commercial bank or trust company having an office or
correspondent in the United States, or an "eligible guarantor institution"
within the meaning of Rule 17Ad-15 under the Exchange Act which is a member of
one of the recognized signature guarantee programs identified in the Letter of
Transmittal (an "Eligible Institution").
 
     If the Letter of Transmittal is signed by a person other than the
registered holder of any Original Notes listed therein, such Original Notes must
be endorsed or accompanied by a properly completed bond power, signed by such
registered holder as such registered holder's name appears on such Original
Notes.
 
     If the Letter of Transmittal or any Original Notes or bond powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and unless waived by the
Company, evidence satisfactory to the Company of their authority to so act must
be submitted with the Letter of Transmittal.
 
     The Exchange Agent and the Depositary have confirmed that any financial
institution that is a participant in the Depositary's system may utilize the
Depositary's Automated Tender Offer Program to tender Original Notes.
 
     All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Original Notes will be
determined by the Company in its sole discretion, which determination will be
final and binding. The Company reserves the absolute right to reject any and all
Original Notes not properly tendered or any Original Notes the Company's
acceptance of which would, in the opinion of counsel for the Company, be
unlawful. The Company also reserves the right to waive any defects,
irregularities or conditions of tender as to particular Original Notes. The
Company's interpretation of the terms and conditions of the Exchange Offer
(including the instructions in the Letter of Transmittal) will be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of Original Notes must be cured within such time as the
Company shall determine. Although the Company intends to notify holders of
defects or irregularities with respect to tenders of Original Notes, neither the
Company, the Exchange Agent nor any other person shall incur any liability for
failure to give such notification. Tenders of Original Notes will not be deemed
to have been made until such defects or irregularities have been cured or
waived.

<PAGE>   42
 
     While the Company has no present plan to acquire any Original Notes which
are not tendered in the Exchange Offer or to file a registration statement to
permit resales of any Original Notes which are not tendered pursuant to the
Exchange Offer (other than the Shelf Registration Statement in connection with
the Original Notes in the aggregate principal amount of $11.0 million held by an
affiliate of the Company), the Company reserves the right in its sole discretion
to purchase or make offers for any Original Notes that remain outstanding after
the Expiration Date or, as set forth below under "-- Certain Conditions to the
Exchange Offer," to terminate the Exchange Offer and, to the extent permitted by
applicable law, purchase Original Notes in the open market, in privately
negotiated transactions or otherwise. The terms of any such purchases or offers
could differ from the terms of the Exchange Offer.
 
     By tendering, each holder will represent to the Company that, among other
things, (i) the Exchange Notes to be acquired by the holder of the Original
Notes in connection with the Exchange Offer are being acquired by the holder in
the ordinary course of business of the holder, (ii) the holder has no
arrangement or understanding with any person to participate in the distribution
of Exchange Notes, (iii) the holder acknowledges and agrees that any person who
is a broker-dealer registered under the Exchange Act or is participating in the
Exchange Offer for the purposes of distributing the Exchange Notes must comply
with the registration and prospectus delivery requirements of the Securities Act
in connection with a secondary resale transaction of the Exchange Notes acquired
by such person and cannot rely on the position of the staff of the Commission
set forth in certain no-action letters, (iv) the holder understands that a
secondary resale transaction described in clause (iii) above and any resales of
Exchange Notes obtained by such holder in exchange for Original Notes acquired
by such holder directly from the Company should be covered by an effective
registration statement containing the selling securityholder information
required by Item 507 or Item 508, as applicable, of Regulation S-K of the
Commission, and (v) the holder is not an "affiliate," as defined in Rule 405 of
the Securities Act, of the Company. If the holder is a broker-dealer that will
receive Exchange Notes for its own account in exchange for Original Notes that
were acquired as a result of market-making activities or other trading
activities, the holder is required to acknowledge in the Letter of Transmittal
that it will deliver a prospectus in connection with any resale of such Exchange
Notes; however, by so acknowledging and by delivering a prospectus, the holder
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act.
 
RETURN OF NOTES
 
     If any tendered Original Notes are not accepted for any reason set forth in
the terms and conditions of the Exchange Offer or if Original Notes are
withdrawn or are submitted for a greater principal amount than the holders
desire to exchange, such unaccepted, withdrawn or non-exchanged Original Notes
will be returned without expense to the tendering holder thereof (or, in the
case of Original Notes tendered by book-entry transfer into the Exchange Agent's
account at the Depositary pursuant to the book-entry transfer procedures
described below, such Original Notes will be credited to an account maintained
with the Depositary) as promptly as practicable.
 
BOOK-ENTRY TRANSFER
 
     The Exchange Agent will make a request to establish an account with respect
to the Original Notes at the Depositary for purposes of the Exchange Offer
within two business days after the date of this Prospectus, and any financial
institution that is a participant in the Depositary's systems may make
book-entry delivery of Original Notes by causing the Depositary to transfer such
Original Notes into the Exchange Agent's account at the Depositary in accordance
with the Depositary's procedures for transfer. Although delivery of Original
Notes may be effected through book-entry transfer at the Depositary, the Letter
of Transmittal or facsimile thereof, with any required signature guarantees and
any other required documents, must, in any case, be transmitted to and received
by the Exchange Agent at the address set forth below under " Exchange Agent" on
or prior to the Expiration Date or pursuant to the guaranteed delivery
procedures described below.

GUARANTEED DELIVERY PROCEDURES
 
     Holders who wish to tender their Original Notes and (i) whose Original
Notes are not immediately available or (ii) who cannot deliver their Original
Notes, the Letter of Transmittal or any other required documents to the Exchange
Agent prior to the Expiration Date, may effect a tender if:
 
          (a) The tender is made through an Eligible Institution;
 
          (b) Prior to the Expiration Date, the Exchange Agent receives from
     such Eligible Institution a properly completed and duly executed Notice of
     Guaranteed Delivery substantially in the form provided by the Company (by
     facsimile transmission, mail or hand delivery) setting forth the name and
     address of the holder, the certificate number(s) of such Original Notes and
     the principal amount of Original Notes tendered, stating that the tender is
     being made thereby and guaranteeing that, within five New York Stock
     Exchange trading days after the Expiration Date, the Letter of Transmittal
     (or a facsimile thereof) together with the certificate(s) representing the
     Original Notes in proper form for transfer or a Book-Entry Confirmation, as
     the case may be, and any other documents required by the Letter of
     Transmittal will be deposited by the Eligible Institution with the Exchange
     Agent; and
 
          (c) Such properly executed Letter of Transmittal (or facsimile
     thereof), as well as the certificate(s) representing all tendered Original
     Notes in proper form for transfer and all other documents required by the
     Letter of Transmittal are received by the Exchange Agent within five New
     York Stock Exchange trading days after the Expiration Date.
 
     Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their Original Notes according to the
guaranteed delivery procedures set forth above.
 
WITHDRAWAL OF TENDERS
 
     Except as otherwise provided herein, tenders of Original Notes may be
withdrawn at any time prior to the Expiration Date.
 
     To withdraw a tender of Original Notes in the Exchange Offer, a written or
facsimile transmission notice of withdrawal must be received by the Exchange
Agent at its address set forth herein prior to the Expiration Date. Any such
notice of withdrawal must (i) specify the name of the person having deposited
the Original Notes to be withdrawn (the "Depositor"), (ii) identify the Original
Notes to be withdrawn (including the certificate number or numbers and principal
amount of such Original Notes), and (iii) be signed by the holder in the same
manner as the original signature on the Letter of Transmittal by which such
Original Notes were tendered (including any required signature guarantees). All
questions as to the validity, form and eligibility (including time of receipt)
of such notices will be determined by the Company in its sole discretion, whose
determination shall be final and binding on all parties. Any Original Notes so
withdrawn will be deemed not to have been validly tendered for purposes of the
Exchange Offer and no Exchange Notes will be issued with respect thereto unless
the Original Notes so withdrawn are validly retendered. Properly withdrawn Notes
may be retendered by following one of the procedures described above under
"Procedures for Tendering" at any time before the Expiration Date.
 
CERTAIN CONDITIONS TO THE EXCHANGE OFFER
 
     Notwithstanding any other term of the Exchange Offer, the Company shall not
be required to accept for exchange, or exchange the Exchange Notes for, any
Original Notes not theretofore accepted for exchange, and may terminate or amend
the Exchange Offer as provided herein before the acceptance of such Original
Notes, if any of the following conditions exist:
 
          (a) any action or proceeding is instituted or threatened in any court
     or by or before any governmental agency with respect to the Exchange Offer
     which, in the reasonable judgment of the Company, might impair the ability
     of the Company to proceed with the Exchange Offer or have a material
     adverse effect on the contemplated benefits of the Exchange Offer to the
     Company or there shall
 
                                       41
<PAGE>   44
 
     have occurred any material adverse development in any existing action or
     proceeding with respect to the Company; or
 
          (b) there shall have been any material change, or development
     involving a prospective change, in the business or financial affairs of the
     Company which, in the reasonable judgment of the Company, would materially
     impair the contemplated benefits of the Exchange Offer to the Company; or
 
          (c) there shall have been proposed, adopted or enacted any law,
     statute, rule or regulation which, in the reasonable judgment of the
     Company, might materially impair the ability of the Company to proceed with
     the Exchange Offer or materially impair the contemplated benefits of the
     Exchange Offer to the Company; or
 
          (d) any governmental approval which the Company shall, in its
     reasonable discretion, deem necessary for the consummation of the Exchange
     Offer as contemplated hereby has not been obtained.
 
     If the Company determines in its sole discretion that any of these
conditions are not satisfied, the Company may (i) refuse to accept any Original
Notes and return all tendered Original Notes to the tendering holders, (ii)
extend the Exchange Offer and retain all Original Notes tendered prior to the
expiration of the Exchange Offer, subject, however, to the rights of holders to
withdraw such Original Notes (see "Withdrawal of Tenders"), or (iii) waive such
unsatisfied conditions with respect to the Exchange Offer and accept all
properly tendered Original Notes which have not been withdrawn. If such waiver
constitutes a material change to the Exchange Offer, the Company will promptly
disclose such waiver by means of a prospectus supplement that will be
distributed to the registered holders of the Original Notes, and the Company
will extend the Exchange Offer for a period of five to 10 business days,
depending upon the significance of the waiver and the manner of disclosure to
the registered holders, if the Exchange Offer would otherwise expire during such
five to 10 business day period.
 
     Holders may have certain rights and remedies against the Company under the
Exchange and Registration Rights Agreement if the Company fails to consummate
the Exchange Offer, notwithstanding a failure of the conditions stated above.
Such conditions are not intended to modify those rights or remedies in any
respect.
 
     The foregoing conditions are for the sole benefit of the Company and may be
asserted by the Company regardless of the circumstances giving rise to such
condition or may be waived by the Company in whole or in part at any time and
from time to time in the Company's sole discretion. The failure by the Company
at any time to exercise the foregoing rights shall not be deemed a waiver of
such right and each such right shall be deemed an ongoing right which may be
asserted at any time and from time to time.
 
TERMINATION OF CERTAIN RIGHTS
 
     All rights under the Exchange and Registration Rights Agreement (including
registration rights) of holders of the Original Notes eligible to participate in
this Exchange Offer will terminate upon consummation of the Exchange Offer
except with respect to the Company's continuing obligations (i) to indemnify the
holders (including any broker-dealers) and certain parties related to the
holders against certain liabilities (including liabilities under the Securities
Act), (ii) to provide, upon the request of any holder of a transfer-restricted
Original Note, the information required by Rule 144(d)(4) under the Securities
Act in order to permit resales of such Original Notes pursuant to Rule 144A,
(iii) to use its best efforts to keep the Registration Statement effective to
the extent necessary to ensure that it is available for resales of transfer-
restricted Notes by broker-dealers for a period of 180 days from the date on
which the Registration Statement is declared effective, and (iv) to provide
copies of the latest version of the Prospectus to broker-dealers upon their
request for a period of 180 days from the date on which the Registration
Statement is declared effective.
 
LIQUIDATED DAMAGES
 
     If (i) the Registration Statement or Shelf Registration Statement is not
filed with the Commission on or prior to 45 days after the Issue Date; (ii)
Registration Statement or the Shelf Registration Statement is not declared
effective within 105 days after the Issue Date; (iii) the Exchange Offer is not
consummated on or
 
                                       42
<PAGE>   45
 
prior to 135 days after the Issue Date or (iv) the Shelf Registration Statement
is filed and declared effective within 135 days after the Issue Date but shall
thereafter cease to be effective (at any time that the Company is obligated to
maintain the effectiveness thereof) without being succeeded within 30 days by an
additional registration statement filed and declared effective (each such event
referred to in clauses (i) through (iv), a "Registration Default"), the Company
will be obligated to pay liquidated damages to each holder of Restricted Notes,
during the period of one or more such Registration Defaults, in an amount equal
to $0.192 per week per $1,000 principal amount of the Notes constituting
Restricted Notes held by such holder until the Registration Statement, the Shelf
Registration Statement or other applicable registration statement is filed, the
Exchange Offer Registration Statement is declared effective and the Exchange
Offer is consummated or the Shelf Registration Statement is declared effective
or again becomes effective, as the case may be. All accrued liquidated damages
shall be paid to holders in the same manner as interest payments on the Notes on
semi-annual payment dates which correspond to interest payment dates for the
Notes. Following the cure of all Registration Defaults, the accrual of
liquidated damages will cease.

FEES AND EXPENSES
 
     All fees and expenses incident to compliance with the Exchange and
Registration Rights Agreement regarding this Exchange Offer shall be borne by
the Company whether or not the Exchange Offer or a Shelf Registration becomes
effective.
 
     The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers, dealers or others
soliciting acceptances of the Exchange Offer. The Company, however, will pay the
Exchange Agent reasonable and customary fees for its services and will reimburse
it for its reasonable out-of-pocket expenses in connection therewith.
 
     The cash expenses to be incurred in connection with the Exchange Offer will
be paid by the Company and are estimated in the aggregate to be approximately
$350,000. Such expenses include registration fees, fees and expenses of the
Exchange Agent and Trustee, accounting and legal fees and printing costs, among
others.
 
     The Company will pay all transfer taxes, if any, applicable to the exchange
of Original Notes pursuant to the Exchange Offer. If, however, a transfer tax is
imposed for any reason other than the exchange of the Original Notes pursuant to
the Exchange Offer, then the amount of any such transfer taxes (whether imposed
on the registered holder or any other persons) will be payable by the tendering
holder. If satisfactory evidence of payment of such taxes or exemption therefrom
is not submitted with the Letter of Transmittal, the amount of such transfer
taxes will be billed directly to such tendering holder.

CONSEQUENCES OF FAILURE TO EXCHANGE
 
     Participation in the Exchange Offer is voluntary. Holders of the Original
Notes are urged to consult their financial and tax advisors in making their own
decisions on what action to take.
 
     The Original Notes which are not exchanged for the Exchange Notes pursuant
to the Exchange Offer will remain restricted securities. Accordingly, such Notes
may be resold only (i) to a person whom the seller reasonably believes is a
qualified institutional buyer (as defined in Rule 144A under the Securities Act)
in a transaction meeting the requirements of Rule 144A, (ii) in a transaction
meeting the requirements of Rule 144 under the Securities Act, (iii) outside the
United States to a foreign person in a transaction meeting the requirements of
Rule 904 under the Securities Act, (iv) in accordance with another exemption
from the registration requirements of the Securities Act (and based upon an
opinion of counsel if the Company so requests), (v) to the Company, or (vi)
pursuant to an effective registration statement and, in each case, in accordance
with any applicable securities laws of any state of the United States or any
other applicable jurisdiction.
 
ACCOUNTING TREATMENT
 
     For accounting purposes, the Company will recognize no gain or loss as a
result of the Exchange Offer. The expenses of the Exchange Offer will be
amortized over the term of the Exchange Notes.

basis consistent with the audited financial statements and in the opinion of
management include all adjustments, consisting solely of normal, recurring
adjustments, necessary to present fairly the information contained therein. The

financial data of the Company for the period from inception (March 5, 1997) to

31, 1998, in the case of the balance sheet data. The selected unaudited pro

(1) Prior to January 1998, certain staffing positions were filled by Prodigy
    employees who were subcontracted to the Company. In the fourth quarter of
    1997, the Company recorded a severance charge related to the elimination of
    13 of these positions.
 
(2) Capital expenditures include equipment purchased through capital leases of
    $26,198 and $2,173 for the period from inception (March 5, 1997) through
    December 31, 1997 and for the three months ended March 31, 1998,
    respectively.
 
(3) EBITDA is defined as net income (loss) plus net interest expense, provision
    for income taxes, depreciation and amortization and severance costs. EBITDA
    is presented as it is commonly used by certain investors to analyze and
    compare operating performance and to determine a company's ability to
    service and/or incur debt. However, EBITDA should not be considered in
    isolation or as a substitute for net income, cash flows or other income or
    cash flow data or as a measure of a company's profitability or liquidity and
    is not a measure in accordance with generally accepted accounting
    principles. EBITDA is not necessarily comparable with similarly titled
    measures reported by other companies.
 
(4) The historical earnings of the Company were insufficient to cover its fixed
    charges for the period from inception (March 5, 1997) to December 31, 1997
    and the three months ended March 31, 1998 by approximately $10.1 million and
    $3.7 million, respectively. On a pro forma basis after giving effect to the
    offering of the Original Notes and the application of the net proceeds
    therefrom, the earnings of the Company would have been insufficient to cover
    its fixed charges for the period from inception (March 5, 1997) to December
    31, 1997 and the three months ended March 31, 1998 by approximately $36.3
    million and $11.5 million, respectively. Fixed charges consist of interest
    expense and that portion of rent expense the Company believes to be
    representative of interest (i.e., one-third of rent expense).
 
(5) Pro forma interest expense assumes that the offering of the Original Notes
    and the application of the net proceeds therefrom had occurred on the first
    day of the period presented. In addition to the stated interest rate on the
    Notes, pro forma interest expense includes amortization of deferred issuance
    costs and discount on the Notes related to the Warrants. Pro forma interest
    expense does not include the pro forma effect of interest income which would
    have been earned on excess cash for the period from inception (March 5,
    1997) through December 31, 1997 and for the three months ended March 31,
    1998.
 
(6) Pro forma balance sheet data assumes the Unit Offering and the application
    of the net proceeds therefrom had occurred on March 31, 1998.
 
(7) In addition to the indebtedness set forth in the above table, at July 15,
    1998 the Company owed Ericsson $1.5 million, which were repaid with the
    proceeds of the Unit Offering, and a stockholder $11.0 million (increased
    from $6.0 million on March 31, 1998), which was refinanced in connection
    with the Unit Offering. After giving effect to such repayment and
    refinancing, pro forma cash and cash equivalents would have been $186.1
    million. Pro forma long term debt and capital lease obligations is net of
    $2.9 million discount to the principal amount of the Notes attributable to
    the Company's estimate of the value of the Warrants issued as part of the
    Units.
 
(8) As of December 31, 1997, the Company had an outstanding letter of credit in
    the amount of $3.5 million. This letter of credit was secured by the amount
    in the restricted cash account. In the first quarter of 1998, the Company
    exercised its early purchase option with regard to the related capital lease
    and the letter of credit was retired. As adjusted amount represents escrowed
    funds that, together with interest received thereon, will be sufficient to
    pay when due the first four semi-annual interest payments on the Notes.
 
(9) Includes $2.9 million attributable to the Company's estimate of the value of
    the Warrants issued as part of the Units. Such estimate was based on a
    valuation of the Common Stock as of December 31, 1997 by a third party
    valuation firm. See "Management Executive Compensation." No assurance can be
    given that the value allocated to the Warrants is indicative of the price at
    which the Warrants may actually trade.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
     The Company was formed in March 1997 and has a limited history of
operations. Thus, historical information set forth herein may not be indicative
of the Company's future operating results and financial condition.
 
     The Company is a provider of telecommunications services, including high
speed Internet access services, on an advanced nationwide network based on ATM
switching technology which is deployed in every POP of the Network. The Company
is currently providing Internet dial access and related services to Prodigy for
its approximately 900,000 subscribers. The Splitrock Network currently reaches
more than 55% of U.S. households by a local call with 56k modem access
(currently the fastest modem speed commercially available over residential phone
lines), including households in every market with a population of at least
100,000 as well as several second tier markets. Upon completion of the Phase II
Expansion, the Network will have approximately 400 active POPs with a physical
presence in all 50 states, reaching over 90% of U.S. households with a local
call.
 
     From the formation of the Company until July 1, 1997 the Company did not
generate any revenue. On July 1, 1997 the Company consummated the Prodigy
Transactions (as defined) following which the Company began providing Internet
dial access and related services to Prodigy for its subscribers. To date, the
Company has generated substantially all of its revenue under its agreement with
Prodigy. See "-- Prodigy Transactions" and "Risk Factors -- Reliance on Prodigy;
Recent Discussions with Prodigy."
 
     The Company recently began generating revenue from two additional
customers. The Company has provided transit services to Orbis, an Internet
connection service provider to businesses, on a month-to-month basis since May
1998. In addition, the Company has signed an agreement with NetworkTwo, a value
added network service provider, to provide VPN services to NetworkTwo's 200
business customers under which the Company began providing services in June
1998. As part of the Company's strategy, the Company intends to add new
customers and services that will maximize traffic on the Network. See
"Business -- Business Strategy."
 
PRODIGY TRANSACTIONS
 
     On June 24, 1997, the Company and Prodigy entered into the Splitrock Full
Service Agreement (the "Prodigy Agreement") pursuant to which the Company agreed
to provide certain network services to Prodigy for its subscribers. The Prodigy
Agreement became effective on July 1, 1997. In order to provide these services
to Prodigy for its subscribers prior to the completion of the Splitrock Network,
on July 1, 1997 the Company acquired, for temporary use, the Legacy Network from
Prodigy, which consisted of substantially all network assets and related
communications equipment owned or leased by Prodigy. Consideration for the
acquisition of the Legacy Network was in the form of the assumption of $5.9
million of liabilities. The foregoing transactions are collectively referred to
herein as the "Prodigy Transactions."
 
     Prodigy Agreement. Under the Prodigy Agreement, the Company provides
Prodigy with network services, including Internet dial access services and other
network connections, and Prodigy pays the Company monthly usage-based or
subscriber-based service charges equal to the lower of: (i) total subscriber
hours for the month multiplied by the contracted hourly usage rate (the
"Usage-Based Rate") or (ii) total subscribers at the month end multiplied by the
fixed monthly charge per subscriber (the "Subscriber-Based Rate"). The
contracted hourly Usage-Based Rate increased by 9.5% on January 1, 1998 and will
increase by 8.7% on January 1, 1999. The fixed monthly Subscriber-Based Rate
does not increase over time. The Prodigy Agreement imposes certain minimum
monthly service charges on Prodigy in the event that the lower of the
Usage-Based Rate or Subscriber-Based Rate calculation is below defined levels.
The minimum monthly service charges are $3.5 million through June 30, 1999 and
will increase by $500,000 beginning each subsequent July 1. Additionally, in the
event the average monthly hours per subscriber (calculated as the total
subscriber hours for the month divided by the total subscribers at the month
end) exceeds 30 hours, the
                                       48
<PAGE>   51
 
Prodigy Agreement provides that Prodigy will be subject to additional fees
("Additional Fees") equal to (a) $1.00, multiplied by (b) the number of average
monthly hours per subscriber in excess of 30 hours, multiplied by (c) the total
subscribers at the month end. Through March 31, 1998 amounts paid by Prodigy
under the Prodigy Agreement were based on the Usage-Based Rate. As a result of
the migration of Prodigy Classic subscribers to Prodigy Internet, since April
1998 such amounts have been based on the Subscriber-Based Rate. Over the
long-term the Company expects to receive amounts from Prodigy based on the
Subscriber-Based Rate, although in the short-term there may be periods when the
Usage-Based Rate applies. As a result, amounts received by the Company from
Prodigy since April 1998 have been, and over the long-term (except for any
Additional Fees) are expected to be, a function of the total number of Prodigy
subscribers as opposed to total subscriber hours. Depending on the relative
growth rates of the number of Prodigy subscribers and total subscriber hours,
the amount of the Company's revenues and the Company's operating margins could
be negatively affected.
 
     The initial term of the Prodigy Agreement expires on June 30, 2001. After
the initial term either party may terminate the Prodigy Agreement upon twelve
months prior written notice. If no notice is received, the term of the Prodigy
Agreement is automatically extended for successive twelve month terms. Under the
Prodigy Agreement the Company is required, among other things, to provide
Prodigy with certain financial and other information, meet certain financial
covenants and meet certain network performance standards. The Company is
required to provide certain credits to Prodigy in the event it fails to meet
certain network performance standards. Prodigy has the right to terminate the
Prodigy Agreement following a cure period in the event of the Company's failure
to comply with certain provisions thereof, including certain network performance
standards. In addition, Prodigy has the right to terminate the Prodigy Agreement
during the initial term without cause by providing twelve months prior written
notice and paying a termination charge of $5.0 million until July 1, 1999 and
$3.0 million thereafter. In the event of certain prolonged network failures,
Prodigy also has the right to enter the Company's premises and cure such
failures.

     Revenue. Prior to July 1, 1997, the Company did not generate any revenue.
Since July 1, 1997 (the date of the consummation of the Prodigy Transactions)
substantially all revenue of the Company has been received from Prodigy under
the Prodigy Agreement.
 
     Prodigy currently offers two services to its subscribers: Prodigy Classic
and Prodigy Internet. Prodigy Internet subscribers generally have higher average
usage, and therefore when Prodigy pays the Company based on the Usage-Based Rate
such subscribers generate greater revenues for the Company. Since April 1998
amounts paid by Prodigy have been based on the Subscriber-Based Rate, which the
Company expects to continue over the long-term. Prodigy Classic subscribers are
expected to decline as Prodigy gradually migrates such subscribers to Prodigy
Internet and discontinues Prodigy Classic service at the end of 1999. Most of
those subscribers are expected to become Prodigy Internet subscribers, although
there can be no assurances in this regard.
 
     During the third quarter of 1997, the first quarter following the
consummation of the Prodigy Transactions, the Company had revenue of $10.7
million.
 
     During the fourth quarter of 1997, the Company had revenue of $12.0
million, an increase of 11.7% from the prior quarter. The increase in revenue
was due primarily to a 12.1% increase in total subscriber usage. While the
average number of total Prodigy subscribers for the fourth quarter decreased by
approximately 3.3%, average subscriber usage increased 15.8% due to a 30.2%
increase in the average number of total Prodigy Internet subscribers, with a
partially offsetting 19.3% decrease in the average number of total Prodigy
Classic subscribers, which traditionally have lower monthly usage than Prodigy
Internet subscribers. Such decrease in Prodigy Classic subscribers was in line
with expectations.
 
     During the first quarter of 1998, the Company had revenue of $16.5 million,
an increase of 37.7% from the prior quarter. The increase in revenue was due
primarily to a 25.4% increase in total Prodigy subscriber usage, as the average
number of total Prodigy subscribers increased by 6.4% for the first quarter. In
addition, the 9.5% increase in the contracted hourly Usage-Based Rate effective
January 1, 1998 contributed to the revenue growth. Average subscriber usage
increased 17.9% due to a 36.4% increase in the average number of total Prodigy
Internet subscribers during the quarter, which was partially offset by an 16.7%
decrease in the average number of total Prodigy Classic subscribers. Such
decrease in Prodigy Classic subscribers was in line with expectations.
 
     The Company expects the number of Prodigy subscribers and subscriber usage
to increase. Amounts due from Prodigy (other than any Additional Fees) are
expected to be based on the Subscriber-Based Rate over the long-term and as a
result, depending on the relative growth rates of the number of Prodigy
subscribers and total subscriber hours, the amount of the Company's revenues and
the Company's operating margins could be negatively affected. Prodigy has
informed the Company that it intends to begin a widespread major U.S. market
advertising campaign in September 1998. In addition, the Company expects the
number of Prodigy Internet subscribers to increase relative to the number of
Prodigy Classic subscribers, and thereby continue to increase average hourly
usage per subscriber, which could result in Additional Fees becoming due to the
Company. The Company is unable to predict when or whether it will receive any
Additional Fees from Prodigy in the future.
 
     Network Related Operating Expenses. Network related operating expenses
include all of the direct costs incurred in connection with designing, deploying
and expanding the Splitrock Network, operating the Splitrock Network and the
Legacy Network, and accessing the IBM Global Services Network. The Company
 
                                       50
<PAGE>   53
 
accounts for its direct Network-related operating expenses in three line items,
Network personnel costs, Network operating costs and Legacy Network costs.
Network personnel costs include all personnel expenses incurred in connection
with deploying, operating and expanding the Splitrock Network. Network operating
costs include all other expenses incurred in connection with deploying,
operating and expanding the Splitrock Network, including assembly costs, line
charges, maintenance costs, travel costs, auxiliary, equipment costs and
collocate charges. Legacy Network costs include all expenses incurred in
connection with operating the Legacy Network, including facility leases, line
charges, personnel costs, occupancy costs, equipment maintenance costs and
access fees for the IBM Global Services Network. Under a transition services
agreement with Prodigy entered into as part of the Prodigy Transactions, certain
of these expenses which were incurred by Prodigy prior to the consummation of
the Prodigy Transactions continued to be paid by Prodigy and the Company
reimbursed Prodigy for such charges or netted such charges against amounts due
from Prodigy. The transition services agreement expired on January 1, 1998,
although the Company continues to reimburse Prodigy for occupancy expenses,
telecommunications line charges and equipment lease payments relating to Legacy
Network POPs that have not yet been decommissioned. The Company assumed no
contractual liability for facility or telecommunications lines as part of the
transition services agreement.
 
     As the expansion of the Splitrock Network progresses, the Legacy Network is
being decommissioned and usage of the IBM Global Services Network is declining.
As of July 15, 1998, there were 65 Legacy Network POPs awaiting decommission
(resulting in duplicative costs) and 20 Legacy Network POPs still in operation.
As POPs are decommissioned, all occupancy and telecommunication line changes are
terminated. The Company has decommissioned 70 of the original 155 Legacy Network
POPs through July 15, 1998. Substantially all Legacy Network POPs are expected
to be decommissioned by the end of 1998. There is typically a lag time of two to
three months between the time the Splitrock Network is operational in any given
area and either the Legacy Network infrastructure for such area is
decommissioned or the IBM Global Services Network is no longer used. As a
result, transition to the Splitrock Network involves a temporary duplication of
costs.
 
     The Company was formed on March 5, 1997 to build the Splitrock Network.
From that time through the end of the second quarter of 1997, the Company had
not yet begun deploying the Splitrock Network nor had it consummated the Prodigy
Transactions. As a result, it incurred limited operating expenses prior to the
third quarter of 1997.
 
     On July 1, 1997, the Company consummated the Prodigy Transactions. During
the third quarter of 1997, the Company incurred approximately $95,000 of Network
personnel costs and approximately $561,000 of Network operating costs. In
addition, during this quarter the Company incurred $13.1 million of Legacy
Network costs. The Network operating costs were comprised primarily of
approximately $470,000 of assembly and engineering design charges paid to Yurie.
The Legacy Network costs incurred in this period included costs to operate the
Legacy Network as well as $5.6 million of usage charges paid relating to the IBM
Global Services Network.
 
     During the fourth quarter of 1997, the Company incurred approximately
$342,000 of Network personnel costs and $1.4 million of Network operating costs.
In addition, during this quarter the Company incurred $12.2 million of Legacy
Network costs. The increase in Network personnel costs was primarily due to the
hiring of approximately 20 technical and accounting employees for The Woodlands,
TX headquarters location. The increase in Network operating costs reflected the
beginning of the Splitrock Network deployment. During this period, the Company
deployed 29 POPs, of which 16 were operational by the end of the period, and
completed its backbone installation. The Network operating costs during this
period primarily consisted of approximately $514,000 of assembly and engineering
design charges paid to Yurie and approximately $551,000 of leased transmission
and local access line charges. The decrease in Legacy Network costs from the
prior quarter primarily resulted from disconnecting underutilized lines and
reduced occupancy and personnel costs, offset in part by expenses incurred
related to new lines installed for the Legacy Network in certain geographic
areas to address capacity issues and increased access charges relating to the
IBM Global Services Network. The Company paid $6.3 million of usage charges
related to the IBM Global Services Network in the fourth quarter of 1997. During
this quarter the Company disconnected 4,330 network access lines which carried a
total monthly rental cost of approximately $130,000. During this quarter the
Company incurred
 
                                       51
<PAGE>   54
 
certain duplicative expenses as a result of the lag between moving Splitrock
Network POPs into production and decommissioning the corresponding Legacy
Network infrastructure.
 
     Prior to January 1, 1998, the Yorktown, NY staff remained employed by
Prodigy and were made available to the Company by Prodigy. The Company
reimbursed Prodigy for the costs related to such employees and recorded them as
Legacy Network expenses. In the fourth quarter of 1997, as part of a downsizing
program in Yorktown, NY, the Company eliminated the need for 13 Prodigy
employees. The Company recorded a charge of approximately $463,000 related to
severance pay for these Prodigy employees. This charge was recorded as a
severance cost in the fourth quarter of 1997. As of January 1, 1998, the
remaining employees at the Yorktown, NY facility and NOC were transferred from
Prodigy's payroll to the Company's payroll. As these remaining employees are
expected to be retained after the Legacy Network is fully decommissioned,
effective January 1, 1998 the Company began recording the personnel expenses
related to such employees as Network personnel expenses rather than Legacy
Network expenses.
 
     During the first quarter of 1998, the Company incurred $1.1 million of
Network personnel costs and $3.1 million of Network operating costs. In
addition, during this quarter the Company incurred $12.3 million of Legacy
Network costs. The increase in Network personnel costs was due to continued
hiring for The Woodlands, TX operations and the change in recording the
personnel costs for Yorktown, NY employees as Network personnel costs as opposed
to Legacy Network costs. The increase in Network operating costs reflected the
continued deployment of the Splitrock Network. By the end of this period, the
Company had deployed 58 POPs, of which 51 were operational. Approximately 77% of
the increase in Network operating costs was due to increased line and backbone
circuit charges. Network operating costs also included assembly and engineering
design charges paid to Yurie in the amount of $470,000. The slight increase in
Legacy Network costs was primarily due to increased usage charges relating to
the IBM Global Services Network as well as expenses incurred related to new
lines installed for the Legacy Network in certain geographic areas to address
capacity issues, offset by the decommissioning of Legacy Network lines (although
during this period duplicative costs were incurred in certain areas as a result
of the lag of such decommissioning) and the change in accounting for the
Yorktown, NY employees described above. During this quarter the Company
disconnected 9,526 Legacy Network lines which carried total monthly rental costs
of approximately $285,000. During this quarter the Company paid $7.3 million of
usage charges related to the IBM Global Services Network.
 
     Prior to April 1, 1998, the Company accessed the IBM Global Services
Network under Prodigy's contract with IBM. During the period from July 1, 1997
to March 31, 1998, Prodigy incurred usage charges to IBM and was reimbursed by
the Company for $19.3 million of these expenses. Effective April 1, 1998, the
Company entered into a new contract with IBM to continue to provide these access
services. This contract provides for significantly higher hourly usage charges
due to the Company's expected short-term use of the IBM Global Services Network
as well as the Company's lack of a long-term relationship with IBM. The Company
anticipates that for the second quarter of 1998 IBM charges will increase
approximately 45% over the first quarter of 1998, but will decline through the
remainder of 1998 as the Splitrock Network is further expanded. Approximately
30% of total subscriber usage was accessed through IBM POPs for the month of May
1998. See "Risk Factors -- Dependence on Suppliers."
 
     Selling, General and Administrative Expenses. Selling, general and
administrative expenses consist of personnel costs relating to executive
management, accounting and finance, sales and marketing and administrative
employees, as well as other miscellaneous expenses such as occupancy costs,
travel expenses and legal fees. In the second quarter of 1997 the Company
incurred limited selling, general and administrative expenses, which primarily
consisted of consulting and legal fees incurred in connection with the Prodigy
Transactions. The Company incurred approximately $125,000, $471,000, $680,000
and $657,000 of selling, general and administrative expenses in the second
quarter of 1997, the third quarter of 1997, the fourth quarter of 1997 and the
first quarter of 1998, respectively. This gradual increase reflects the
development of the Company's executive, accounting and administrative support
departments. The decrease in selling, general and administrative expenses in the
first quarter of 1998 compared to the fourth quarter of 1997 was due to certain
non-recurring expenses incurred in the fourth quarter of 1997, primarily
increased travel costs, bonuses paid to employees and other miscellaneous costs.
The Company believes that selling, general and administrative expenses will
begin increasing at a greater rate in the third quarter of 1998, when the
Company plans to
                                       52
<PAGE>   55
 
(i) begin hiring additional sales and marketing personnel and (ii) continue the
implementation of its advanced business support systems.
 
     Depreciation and Amortization. Depreciation and amortization in the third
and fourth quarter of 1997 consisted almost exclusively of depreciation of
Legacy Network equipment acquired as part of the Prodigy Transactions. Legacy
Network equipment was recorded at approximately $5.9 million based on the fair
value of the consideration paid. Approximately 80% of the equipment acquired was
depreciated over nine months, the expected useful life of the Legacy Network,
with the remaining 20% depreciated over 36 months. Therefore, on March 31, 1998,
80% of Prodigy equipment acquired was fully depreciated. All Splitrock
Network-related equipment begins to be depreciated as it is placed into service
using a straight-line basis over three years. Depreciation will increase as the
Phase II Expansion progresses. The Company incurred depreciation expenses of
$1.7 million, $1.8 million and $2.8 million in the third quarter of 1997, the
fourth quarter of 1997 and the first quarter of 1998, respectively.
 
     Interest Expense. Historical interest expense is related to capital leases
on equipment and loans from a stockholder of the Company. The Company incurred
interest expense of approximately $113,000, $122,000 and $349,000 in the third
quarter of 1997, the fourth quarter of 1997 and the first quarter of 1998,
respectively.
 
     Interest Income. Interest income relates to the interest earned on
investments of cash on hand in commercial paper and money market accounts. The
Company recorded interest income of approximately $137,000, $181,000 and
$107,000 in the third quarter of 1997, the fourth quarter of 1997 and the first
quarter of 1998, respectively.
 
     Provision for Income Taxes. No provision for income taxes has been
recognized as the Company had operating losses for both tax and financial
reporting purposes for the period from inception (March 5, 1997) to December 31,
1997 and for the three months ended March 31, 1998.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Historical
 
     Previous Financings. The Company was founded in March 1997 by Mr. Kwok L.
Li and Mr. William R. Wilson. Since its inception, the Company has raised
approximately $11.8 million (excluding a $10.0 million note that was converted
into equity) through private sales of debt (of which $0.8 million has been
repaid) and $31.6 million through private sales of equity (including the
conversion into equity of such $10.0 million convertible note).
 
     Through various transactions since March 1997, Mr. Li and Linsang, a
technology investment company controlled by Mr. Li, have invested approximately
$21.8 million in debt (including the convertible note described above) and $7.5
million in equity in the Company. Of the amount that Mr. Li and Linsang have
loaned to the Company, $0.8 million has been repaid and the $10.0 million
convertible note was converted into 16.0 million shares of Common Stock of the
Company. The remaining debt outstanding is represented by demand notes which
bear annual interest of 9.75% and mature on the earlier of written demand or
December 1, 2002. Such indebtedness was refinanced in connection with the Unit
Offering. In connection with such refinancing, Linsang purchased 11,000 Units in
the Unit Offering.
 
     On August 18, 1997, Roy Wilkens and Sandra Wilkens purchased 800,000 shares
of the Common Stock of the Company for $0.5 million. Mr. Wilkens became a member
of the Board of Directors of the Company in April 1998.
 
     On September 22, 1997, Orient Star, a wholly owned subsidiary of Carso (the
controlling stockholder of Prodigy), purchased 20.0 million shares of Common
Stock of the Company for $12.5 million. The transaction price included an
option, exercisable through September 18, 1998, to subscribe for an additional
5.0 million shares of Common Stock for $3.1 million. The option, if exercised,
would result in Orient Star holding approximately 30.2% of the Common Stock of
the Company. The Company expects Orient Star to exercise the option. Samer
Salameh, the President of Prodigy, an affiliate of Carso, became a member of the
Board of Directors of the Company in April 1998.
 
     In June 1998, Clark McLeod, CEO of McLeodUSA, Incorporated ("McLeodUSA"), a
regional telecommunications firm in the Midwest, exercised in full a stock
option previously granted to him and
 
                                       53
<PAGE>   56
 
purchased 1.0 million shares of Common Stock of the Company for $1.1 million.
Mr. McLeod became a member of the Board of Directors of the Company in May 1998.
 
     In addition, through March 31, 1998 the Company had arranged $28.4 million
in equipment financing, including $27.4 million related to network-related
equipment primarily from equipment vendors and $1.0 million related to office
equipment from vendors and leasing companies. The Company also assumed
approximately $5.9 million in liabilities pursuant to the Prodigy Transactions.
See " Prodigy Transactions."
 
     Capital Expenditures. As of March 31, 1998 the Company had recorded capital
expenditures (exclusive of depreciation) of approximately $46.8 million, of
which $5.9 million represents assets acquired from Prodigy. The following table
sets forth such capital expenditures by category:

  Future
 
     The Company's future liquidity and capital requirements will result
primarily from its debt service and principal repayment obligations, lease
obligations, capital expenditures and other expenses to be incurred in
connection with the expansion of the Splitrock Network, acquisitions and joint
ventures and general working capital purposes. Through March 31, 1998, the
Company had spent approximately $23.9 million on the Phase I Buildout, which was
substantially completed in April 1998, and $12.7 million on the Phase II
Expansion. The Company anticipates making an additional $141.1 million of
capital expenditures in connection with the Phase II Expansion. The Company
expects to spend approximately $47.4 million to construct approximately 330
additional POPs, approximately $81.5 million to deploy advanced processing
equipment and software to enhance and accelerate the Company's ability to
provide value added services, such as ISDN video, web hosting and VPN, and
approximately $12.2 million to augment the Company's network management
infrastructure. Of these amounts, the Company has spent $1.7 million since March
31, 1998. The Company has a commitment to purchase $9.0 million of additional
equipment from Yurie prior to January 1, 1999. In addition, as of March 31, 1998
the Company had aggregate operating and capital lease payments of $6.8 million,
$9.6 million and $7.2 million due in the last nine months of 1998, 1999 and
2000, respectively. The Company currently believes that cash flow from operating
activities, together with the net proceeds of the Notes and future borrowings
from Linsang, if any, will be sufficient to fund the Company's expected capital
expenditures, working capital, lease obligations and debt service requirements.
Linsang has not committed to make any additional credit available to the
Company.
 
     Any future acquisitions, joint ventures or similar transactions may require
additional financings and there can be no assurance that such financings will be
available to the Company on acceptable terms or at all.
 
     The Company is highly leveraged. At March 31, 1998, on a pro forma basis
after giving effect to the offering of the Original Notes and the application of
the net proceeds therefrom, the Company would have had $279.2 million of total
indebtedness, representing approximately 93.4% of the Company's total
capitalization. See "Capitalization." In addition, the terms of the Notes permit
the Company to incur certain other indebtedness. There can be no assurance that
the Company will have sufficient cash flow to pay the interest expense or the
principal associated with the Notes or such indebtedness. The highly leveraged
position of the Company could have a material adverse effect on its ability to
obtain financing for acquisitions, joint ventures or other purposes.
 
     The Company recorded EBITDA of approximately $(6.3) million and $(0.6)
million for the period from inception (March 5, 1997) to December 31, 1997 and
the three months ended March 31, 1998, respectively (For the same periods, the
Company reported net losses of $10.1 million and $3.7 million). On a pro forma
basis after giving effect to the Offering and the application of the net
proceeds therefrom, the Company would have reported net losses of $36.3 million
and $11.5 million for the period from inception (March 5, 1997) to
 
                                       54

December 31, 1997 and the three months ended March 31, 1998, respectively. The
Company expects such net losses to continue as the Company focuses on increasing
its customer base, implementing its business strategy and developing new
services. See "Summary Recent Developments." The historical earnings of the
Company were insufficient to cover its fixed charges for the period from
inception (March 5, 1997) to December 31, 1997 and the three months ended March
31, 1998 by approximately $10.1 million and $3.7 million, respectively. On a pro
forma basis after giving effect to the offering of the Original Notes and the
application of the net proceeds therefrom, the earnings of the Company would
have been insufficient to cover its fixed charges for the period from inception
(March 5, 1997) to December 31, 1997 and the three months ended March 31, 1998
by approximately $36.3 million and $11.5 million, respectively.
 
     The Company's ability to meet its debt service obligations, to finance
planned capital expenditures, lease payments or acquisitions or to comply with
certain covenants contained in the Indenture will depend upon the Company's
future performance, which will be subject to general economic conditions and to
financial, business, competitive, legislative, regulatory and other factors
affecting its operations, many of which are beyond the Company's control. In
addition, for the foreseeable future the Company's financial performance will be
dependent on Prodigy. There can be no assurance that the Company's business will
be able to generate cash flow at levels sufficient to satisfy its debt service
and other requirements, although management expects cash received from the Unit
Offering to provide sufficient sources of liquidity for at least the next twelve
months. If in the future the Company is unable to generate sufficient cash from
its operations to make scheduled interest payments on the Notes, to pay the
Notes at maturity, or to meet other obligations and commitments, the Company may
be required to adopt one or more alternatives, such as refinancing or
restructuring its indebtedness, reducing or delaying planned expansion, selling
assets or raising additional debt or equity. There can be no assurance that the
Company will be able to implement any of these alternatives on satisfactory
terms or at all. In addition, the terms of existing or future debt agreements,
including the Indenture, may prohibit the Company from adopting some of these
alternatives. See "Description of the Notes."
 
YEAR 2000
 
     The year-2000 issue is the result of computer programs being written using
two digits, rather than four digits, to define the applicable year. 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 major system failure or
miscalculations, including an inability to process transactions, send invoices
or engage in similar normal business activities. Due to its reliance on computer
hardware and software, the Internet and related service industries are highly
susceptible to the year-2000 issue. If the year-2000 issue should cause
widespread problems across the Internet, usage can be expected to decline
dramatically. Such an event would have a material adverse effect on the
Company's financial condition and results of operations, the nature and extent
of which cannot reasonably be determined by the Company on the basis of
information currently available to it. The Company has not prepared a
contingency plan and does not expect to do so in light of the uncertainty of the
impact of year-2000 issues on the Internet as a whole and the Company's
anticipated schedule to be year-2000 compliant before the end of 1999.
 
     The Company is currently in the process of evaluating its operations and
both its information technology systems and its non-information technology
systems to determine its own vulnerability to the year-2000 issue. The Company
relies heavily on non-information technology systems in the conduct of its
operations and has determined that substantially all of such systems are
year-2000 compliant. Certain network-monitoring software, which is used by the
Company to monitor network equipment (POPs) on the Legacy Network, is not
year-2000 compliant, but as part of the Company's Phase II Expansion,
substantially all of the Legacy Network POPs are scheduled to be decommissioned
by the end of 1998 and such network-monitoring software will no longer be used
by the Company. With respect to the Company's database inventory software, used
to capture data about the network configuration, including location of equipment
and maintenance, the Company has purchased and is currently installing year-2000
compliant software to replace its existing software. Installation is scheduled
to be completed by the end of 1998, and the cost of such purchase and
installation is not material. The Company has also determined that certain other
of its software systems are not year-2000 compliant. The Company believes that,
with modifications and upgrades to such software,
 
                                       55
<PAGE>   58
 
which are scheduled to occur in the ordinary course of business, it will be
fully year-2000 compliant by the end of 1999. The Company is continuing its
evaluation of the remaining areas impacted by year-2000 issues, including
Internet interfaces, facility matters and equipment vendors, but does not expect
to incur material costs in connection with making its software year-2000
compliant. To date, the Company has not incurred material costs in ensuring
year-2000 compliance.
 
     The Company is also dependent upon the ability of its customers to ensure
that their software and equipment is year-2000 compliant. The Company has
initiated formal communications with Prodigy to determine the extent to which
the Company is vulnerable to Prodigy's own year-2000 issues, if any. Prodigy has
informed the Company that Prodigy Classic may not be year-2000 compliant.
Prodigy is in the process of migrating users to Prodigy Internet, which is
year-2000 compliant, and plans to discontinue Prodigy Classic service by the end
of 1999. However, there can be no guarantee that Prodigy Classic or systems of
future customers on which the Company may rely will be timely converted, or that
a failure to convert, or a conversion that is incompatible with the Company's
systems, would not have a material adverse effect on the Company.
 
                               INDUSTRY OVERVIEW
 
     The Company believes that it is well-positioned to capture revenue
opportunities in the growing Internet services market. As a broad-based ISP, the
Company utilizes an advanced ATM-to-the-edge Network to offer services that
either directly address Internet connectivity (dial access and transit) or which
leverage Internet technology to provide cost-effective alternatives to
traditional corporate network solutions (VPN). While the Company is considering
broadening its service offerings to optimize Network utilization, the Company
believes that a significant amount of its revenues for the foreseeable future
will continue to be derived from Internet related applications.
 
     The Internet. The Internet is a global collection of interconnected
computer networks that allows commercial organizations, educational
institutions, government agencies and individuals to communicate electronically,
access and share information and conduct business. The networks that comprise
the Internet are connected in a variety of ways, including by the public
switched telephone network ("PSTN") and by high speed, dedicated leased lines.
Over time, as businesses have begun to utilize e-mail, file transfer and, more
recently, intranet and extranet services, commercial usage has become a major
component of Internet traffic.
 
     In order for an end-user to access the Internet, a local network connection
is required to an ISP's local facilities. For large, communication-intensive
users and for content providers, these connections are typically unswitched,
dedicated connections provided by incumbent local exchange carriers ("ILECs") or
CLECs, either as independent service providers or, in some cases, by a company
which is both a CLEC and an ISP. For residential and small and medium business
users, these connections are generally PSTN connections obtained on a dial-up
access basis as a local exchange telephone call. This collection of
interconnected networks makes up the Internet. A key feature of Internet
architecture is that a single dedicated channel between communication points is
never established, which distinguishes Internet-based services from the PSTN.
 
     Internet Market Size and Growth. The Internet services industry is one of
the fastest growing segments of the global telecommunications market. Forrester
estimates that the U.S. market for Internet and related services, including
advanced Internet applications such as VPN, voice communications, fax and video
conferencing, was approximately $6.2 billion in 1997 and will grow to
approximately $49.7 billion in 2002, reflecting a compound annual growth rate of
over 50%. The Company believes that Internet dial access and transit services,
VPN services and enhanced business services represent three of the fastest
growing segments of the industry.
 
     Internet Access. Internet access services represent the means by which ISPs
interconnect either businesses or individual consumers to the Internet's
resources or to corporate intranets and extranets. Access services include
dial-up access for individuals and small businesses and high-speed dedicated
access (transit services) used primarily by mid-sized and larger organizations.
According to Forrester, business access
 
                                       56
<PAGE>   59
 
services are projected to grow at a compound annual growth rate of approximately
75%, from approximately $1.0 billion in 1997 to approximately $16.0 billion in
2002.
 
     The demand for access services is driven by the end-user's ability and
desire to gather data and communicate or interact with others. Over the past few
years, many organizations have established Web pages on the Internet in order to
convey a variety of information to end-users. Compounding this growth in
information available over the Internet has been a dramatic increase in the
number of ISPs providing access and related services to end-users. According to
IDC, there are currently over 4,000 ISPs in the U.S., consisting of national,
regional and local providers, of which the Company believes only a small
percentage have access to their own nationwide backbone network infrastructure.
These ISPs have exposed a broad population of users to the opportunities
available over the Internet, resulting in a large and growing group of people
who are accustomed to using networked computers for a variety of purposes,
including e-mail, electronic file transfers, on-line computing and electronic
financial transactions. According to IDC, the number of Internet users worldwide
reached approximately 60.0 million in 1997 and is forecasted to grow to 173.0
million by the year 2000.
 
     The ISP market is segmented into large national or multinational ISPs
("Tier 1 ISPs"), which are typically full-service providers that offer a broad
range of Internet access and value-added services to businesses and regional and
local ISPs ("Tier 2 ISPs" and "Tier 3 ISPs"), which typically offer a smaller
range of products and services to both individuals and business customers. Tier
1 ISPs also provide wholesale services by reselling capacity on their networks
to smaller regional and local ISPs, thereby enabling these smaller ISPs to
provide Internet services on a private label basis without building their own
facilities. The Company believes that the top six Tier 1 ISPs represented
approximately 50% of the market for business connectivity and value-added
services. Tier 1 ISPs exchange Internet traffic at multiple public peering
points known as network access points ("NAPs") and through private peering
arrangements.
 
     VPNs. The Company believes that many businesses desire to utilize VPNs as a
lower-cost alternative to certain traditional telecommunications services.
Historically, many corporations established and maintained their own private
wide-area networks to provide network-based services, such as transaction
processing, to their customers and to coordinate operations between employees,
suppliers and business partners. Despite the attractive capabilities of private
networks, however, limitations of many private WANs have impeded or reduced the
effectiveness of their use. These networks, which traditionally have required
the use of leased telephone lines with dedicated bandwidth and the purchase of
vendor-specific networking equipment and software, are inherently expensive to
set up, operate and maintain. The Company believes that VPNs present a
cost-effective alternative to WANs since VPNs (i) eliminate the need to invest
significant amounts in proprietary equipment and software, (ii) securely and
efficiently connect multiple, geographically dispersed locations, (iii) provide
global remote access capabilities and (iv) offer a full range of value added
services, such as videoconferencing, that meet a company's particular networking
needs.
 
     Enhanced Business Services. In addition to Internet access and VPN
services, business customers increasingly are seeking a variety of enhanced
products and applications to take full advantage of the Internet. The principal
enhanced services currently available to companies are Web hosting, including
hosting of intranet sites, e-mail outsourcing, e-mail broadcast and security.
Forrester forecasts that enhanced business services revenues will grow from
approximately $0.4 billion in 1997 to approximately $10.5 billion in 2002,
representing a compound annual growth rate of 92%.
 
     Development of Network Technology. The Company has designed, deployed and
is in the process of expanding an advanced nationwide telecommunications network
based on ATM-to-the-edge switching technology. The pervasive deployment of ATM
switches throughout the Network enables the Company to create a multi-service
platform by which to expand its service offerings to provide fully integrated
data, video and voice services and to incorporate future technological
innovations into its architecture with a lower incremental investment than that
required by other, less flexible, networks.
 
     Most networks currently in operation use either circuit switching or packet
switching. Circuit switching operates by dedicating a circuit, or fixed amount
of bandwidth, to each end device. Circuit switching's use of
 
                                       57
<PAGE>   60
 
dedicated circuits provides high quality service for all network traffic, but,
since information is not continuously transmitted, the dedicated circuits are
often inefficiently and expensively idle.
 
     Frame relay, a packet switching technology, was introduced in 1990 as a
method of connecting local area networks ("LANs") over WANs by using flexible
bandwidth allocation to lower the cost of transmission. Frame relay uses
"packets' or "frames" to transmit traffic, thereby allowing the same bandwidth
to be shared by many users, each using the bandwidth only for the time required
to transmit a packet. Designed primarily for data transmission, frame relay
cannot guarantee high quality transmission of voice and video. Currently, frame
relay is widely used to transmit data over WANs, including the Internet. Due to
the substantial increase in data traffic, however, today's frame relay networks
are being used to transmit more traffic than they were designed to support,
resulting in network congestion.
 
     To increase a frame relay network's switching capacity to meet increased
data demands and alleviate congestion, sophisticated software is required. To
run this software, the network must be upgraded with powerful, intelligent
processors. The costs of these high-end processors required to switch frame
relay traffic at the speeds needed in today's data network backbones are very
high. Therefore, as data traffic increases, upgrading a frame relay network
becomes more costly and inefficient and ultimately impractical.
 
     Faced with the limitations of frame relay, telecommunications service
providers are installing ATM switches, a newer packet switching technology, in
the backbones of their existing networks. ATM segments data, video and voice
traffic into small, uniform-sized "cells," rather than the larger, variable-size
"packets" or "frames" used in frame relay. The addition of ATM backbone switches
upgrades a network's performance by increasing switching capabilities at the
network's core. ATM's cell-based architecture increases bandwidth utilization
and seeks to provide consistent quality of service and predictability for all
traffic types.
 
     ATM is the first standard protocol to permit reliable service for all
traffic types, allowing the consolidation of circuit switching and packet
switching networks into a single ATM network for data, video and voice. A single
ATM network offers the potential for economies of scale and streamlining of
network operations. The standardization of ATM has allowed for compatibility of
ATM equipment and interoperability of ATM among a wide variety of interfaces and
vendors.
 
     The U.S. government was among the first to deploy ATM technology. Its
initial decision to use ATM was motivated by its desire to consolidate many
discrete networks onto a single network, thus significantly reducing cost. The
U.S. government was able to deploy ATM across geographic boundaries because ATM
was quickly accepted as an international standard, and the government soon
discovered the effectiveness and efficiency of ATM as a global networking
technology.
 
     Several telecommunications service providers began offering trial ATM
services in the early 1990s. These services were available only for high speed
traffic and at high prices and, therefore, made ATM attractive only to users
with significant bandwidth needs. Driven by increasing competition and the rapid
growth of data traffic on frame relay systems, a number of telecommunications
service providers began deploying ATM for use in their network backbones to
manage heavy loads of user traffic and thereby relieve network congestion. Until
recently, providers have continued to install ATM primarily in their network
backbones and typically have not offered ATM service directly to end users.
 
     In 1996, certain telecommunications service providers announced plans to
begin offering ATM services directly to end users at prices competitive with
similar packet switching and circuit switching access services. To utilize these
direct ATM services, an end user needs ATM access products either located at the
local office of a telecommunications service provider (in close proximity to the
end user) or deployed by the end user in its private network. Access products
provide the end user with network access through multiple network interfaces,
traffic concentration and data protocol translation.
 
     ATM access products are well suited to provide efficient connectivity to
ATM networks, facilitate transmission of a variety of traffic types at varying
speeds and accommodate a mix of end user applications on a single network. In
addition, ATM access products have the potential to lower the cost to end users
of transmitting data, video and voice communications. Management believes that
the Splitrock Network contains more ATM-based switches than that of any other
commercial network.

                                    BUSINESS
 
GENERAL
 
     The Company is a provider of telecommunications services, including high
speed Internet access services, on an advanced nationwide network based on ATM
switching technology which is deployed in every POP of the network. The
pervasive deployment of ATM switches throughout the Network enables the Company
to serve as a broad-based ISP through the creation of a multi-service platform
which efficiently delivers IP, frame relay and other Internet services. This
flexibility will allow the Company to expand its service offerings to provide
fully integrated data, video and voice services and to incorporate future
technological innovations into its Network architecture with a lower incremental
investment than that required by other, less flexible, networks. The Company
currently provides nationwide Internet dial access and related services to
Prodigy, the third largest U.S. ISP measured in minutes on-line, for its
approximately 900,000 subscribers. In addition, the Company has begun providing
Internet transit services to Orbis, an Internet connection service provider to
businesses, and VPN services to NetworkTwo, a value added network service
provider. For the quarter ended March 31, 1998, the Company had revenues of
$16.5 million.
 
     The Splitrock Network currently reaches more than 55% of U.S. households by
a local call with 56k modem access (currently the fastest modem speed
commercially available over residential phone lines), including households in
every market with a population of at least 100,000 as well as several second
tier markets. From September 1997 to April 1998, the Company engaged in the
Phase I Buildout which resulted in the deployment of the nationwide ATM backbone
portion of the Splitrock Network and POPs in 70 metropolitan areas across the
nation. Upon completion of the Phase II Expansion, the Network will have
approximately 400 active POPs with a physical presence in all 50 states,
reaching over 90% of U.S. households with a local call.
 
     In order to provide services to Prodigy while the Splitrock Network was
being deployed, on July 1, 1997 the Company acquired the Legacy Network and
began immediately providing Internet dial access and related services to Prodigy
for its approximately 900,000 subscribers. Additionally, the Company has an
agreement with IBM to use the IBM Global Services Network to cover market areas
that are served neither by the Splitrock Network nor the Legacy Network. The
Company currently handles more than 750 million minutes of Internet traffic per
month for Prodigy (currently the Company's only Internet dial access customer),
with over 60% of the traffic flowing on the Splitrock Network, approximately 30%
on the IBM Global Services Network and the remainder on the Legacy Network. As
the Phase II Expansion progresses, Legacy Network POPs will be decommissioned
and access to specific IBM Global Services Network POPs will be terminated when
appropriate. Substantially all Legacy Network POPs are expected to be
decommissioned by the end of 1998 and usage of the IBM Global Services Network
is expected to be terminated by the end of the second quarter of 1999.
 
COMPETITIVE ADVANTAGES
 
     Since July 1997, the Company has provided Internet dial access services to
Prodigy for its approximately 900,000 subscribers. The Company believes it
benefits from the following competitive advantages which will assist it in
implementing its business strategy:
 
          Flexible and Efficient New Network Infrastructure. The Splitrock
     Network is designed to provide reliable, flexible and efficient services to
     the Company's current and future customers. Since the Splitrock Network is
     newly-designed (and not based on or an upgrade to an older network), the
     Company believes the Network contains many features that are not present in
     older networks and is able to flexibly incorporate future developments and
     innovations. Older networks were typically designed to provide one type of
     service, such as voice or data, and are less efficient at carrying other
     traffic. Unlike many networks which deploy ATM technology only along the
     core sites in the backbone, the Splitrock Network deploys ATM-to-the-edge
     at every core site, hub site and remote site. See "Business -- Splitrock's
     Network." Each POP is supported by the Lucent LDR200 switch which the
     Company believes provides significant quality of service advantages over
     typical ATM backbone switches. Management believes that the
 
                                       59
<PAGE>   62
 
     Network contains more ATM-based switches than that of any other commercial
     network. This pervasive use of ATM technology and the Lucent LDR200 switch
     enables the Company to create a multi-service platform which delivers IP,
     frame relay and other Internet services. In addition, ATM-to-the-edge
     provides additional capabilities to expand the Company's service offerings
     to provide fully integrated data, video and voice services and to
     incorporate future technological innovations into the Splitrock Network
     architecture with a lower incremental investment than that required by
     other, less flexible, networks.
 
          Providing of Wholesale Internet Dial Access and International
     Services. The Company currently provides wholesale Internet data access
     services to Prodigy for its approximately 900,000 subscribers. The Company
     intends to market Internet dial access services directly to ISPs rather
     than to individual end-users. As a result, unlike many providers of network
     services, the Company does not intend to compete against its ISP customers,
     thereby broadening the potential customer base to include those ISPs
     unwilling to strengthen their competitors with their own network business.
     Furthermore, the Company believes it will be viewed as a non-competing
     vendor and, thus a potential partner, by major foreign and regional
     telecommunications carriers, providing an alternative to their primary U.S.
     competitors for delivering data, video and voice services.
 
          Experienced Management Team. The Company's co-founders, Kwok L. Li,
     Chairman of the Board and Chief Technical Officer, and William R. Wilson,
     President and Chief Executive Officer, have assembled a management team
     with significant data and voice communications experience. The 10 most
     senior executives and managers of the Company have an average of over 12
     years experience in the data and voice communications industry. Previously,
     Mr. Li and Mr. Wilson were both senior executives at the predecessor
     corporation of WilTel, a wholesale provider of telecommunications services.
     During their tenure WilTel designed, constructed, developed and managed
     modern packet switched networks (including frame relay and ATM) and
     marketed related services. At the time of the sale of Yurie to Lucent in
     May 1998, Mr. Li was a Director, Vice Chairman and Chief Technical Officer
     at Yurie, where he created and designed the Lucent LDR200 switch which is a
     key component of the Splitrock Network.
 
BUSINESS STRATEGY
 
     Key elements of the Company's business strategy include:
 
          Complete the Expansion of the Advanced Network Infrastructure. The
     Company has designed, deployed and is in the process of expanding the
     Splitrock Network, an advanced nationwide telecommunications network based
     on ATM-to-the-edge switching technology. Through March 31, 1998, the
     Company had spent approximately $23.9 million on the Phase I Buildout,
     which was substantially completed in April 1998, and $12.7 million on the
     Phase II Expansion. The Company anticipates that completion of the Phase II
     Expansion will require an additional $141.1 million of capital
     expenditures. The Company expects to spend approximately $47.4 million to
     construct approximately 330 additional POPs, approximately $81.5 million to
     deploy advanced processing equipment and software to enhance and accelerate
     the Company's ability to provide value added services, such as ISDN video,
     web hosting and VPN, and approximately $12.2 million to augment the
     Company's network management infrastructure. Of these amounts, the Company
     has spent $1.7 million since March 31, 1998. The Company believes that
     having ATM-to-the-edge results in: (i) a more easily upgradeable network;
     (ii) the ability to efficiently add new services at a lower incremental
     investment; (iii) improved network reliability; (iv) interoperability with
     other network platforms; and (v) improved network manageability.
 
          Offer a Comprehensive Range of Services to Optimize Network
     Utilization. Given the fixed cost nature of the Splitrock Network's
     infrastructure, the Company seeks to increase total network utilization
     primarily by targeting providers of business services (daytime intensive
     traffic) and, to a lesser extent, providers of consumer services (evening
     intensive traffic) to balance the Network's usage throughout a 24-hour
     period. The Network's flexibility will provide for service innovation
     (including data, video and voice services) with lower incremental
     investment than less flexible networks. To offer new services, the Company
     will only need to add the appropriate protocol processors and billing and
     service management systems without changes to the core ATM switching
     platform. Therefore, the Company believes it will be
 
                                       60
<PAGE>   63
 
     able to maximize Network utilization by offering both daytime
     business-oriented services (such as video conferencing and VPN services)
     and evening-time consumer-oriented services (such as Internet dial access
     services). The ability of the Company to offer a wide range of services
     will enhance its ability to optimize traffic at all times of the day,
     thereby increasing revenue and profitability. As its business strategy is
     implemented, the Company will evaluate offering complementary services as
     they are required by its customer base.
 
          Development of Advanced Business Support Systems. Through the
     development of scalable business support systems, the Company believes that
     it has the opportunity to establish a competitive advantage relative to
     traditional network service providers. Traditional network service
     providers typically operate extensive legacy business support systems with
     compartmentalized architectures that limit their ability to scale rapidly
     and introduce enhanced services and features. In connection with the
     expansion of the Splitrock Network the Company is creating business support
     systems with an architecture designed to maximize both reliability and
     scalability. All database and billing systems will run on a PC or UNIX
     distributed architecture rather than centralized mainframe systems.
 
          Expand Target Market Opportunities. IDC estimates that the total
     number of U.S. companies with Internet access will grow from an estimated
     1.5 million, or 20.0% of total U.S. companies, in 1996 to 4.1 million, or
     53.0% of total U.S. companies, in 2000. IDC also estimates that the number
     of U.S. households with a personal computer and a modem will grow from an
     estimated 8.8 million, or 24.0% of all U.S. households with a personal
     computer in 1996, to 39.4 million, or 58.0% of all U.S. households with a
     personal computer in 2000. IDC estimates that there are currently over
     4,000 ISPs in the U.S., consisting of national, regional and local
     providers, of which the Company believes only a small percentage have
     access to their own nationwide backbone network infrastructure. The Company
     intends to capitalize on this expected growth in demand for network
     services by aggressively marketing its services through a variety of
     distribution channels and evaluating strategic alliances and acquisitions
     as they present themselves. The Company believes that utilizing a range of
     distribution channels will enable it to cost-effectively reach a broad base
     of potential customers. The Company currently intends to develop and use a
     direct sales force (which it expects to begin hiring in the second half of
     1998) to attract ISPs, carriers, value added service providers and medium
     and large businesses. In addition, the Company intends to use alternative
     distribution channels, including agents, resellers and wholesalers, to gain
     access to a substantially larger base of potential customers than the
     Company could otherwise initially address through its direct sales force.
     Through the combination of a direct sales force and alternative
     distribution channels, the Company will seek to rapidly increase
     revenue-producing traffic on its Network.
 
          The Company also intends to evaluate strategic alliances and
     acquisitions that could provide additional traffic over the Splitrock
     Network. While the Company is primarily focused on the domestic services
     market, it believes the demand for Internet services outside the U.S. will
     grow over the next few years. As a result, the Company will evaluate
     opportunities, primarily in Latin America, to partner with strong,
     established telecommunications service providers. For example, the Company
     will consider entering into international alliances to originate and
     terminate international traffic on the Splitrock Network.
 
          Provide Superior Comprehensive Customer Service. Splitrock believes
     that superior customer service is a critical element in attracting and
     retaining customers, and expanding value added services to existing
     customers. In particular, the Company believes it is critical to maintain
     two geographically dispersed NOCs, each of which is able to monitor the
     entire Network and provide rapid problem resolution. The Company has
     established a 24-hours per day, seven days per week NOC at its Yorktown, NY
     facility. In addition, a new 24-hours per day, seven days per week NOC
     recently became fully operational at The Woodlands, TX facility.
 
SPLITROCK'S NETWORK
 
     Overview. The Splitrock Network is a facilities-based nationwide ATM-based
commercial telecommunications network. The Network currently reaches more than
55% of U.S. households by a local call with 56k
 
                                       61
<PAGE>   64
 
modem access (currently the fastest modem speed commercially available over
residential phone lines), including every market with a population of at least
100,000 as well as several second-tier markets. Upon completion of the Phase II
Expansion, the Splitrock Network will have approximately 400 active POPs with a
physical presence in all 50 states, reaching over 90% of U.S. households with a
local call.
 
     On June 24, 1997, the Company entered into the Prodigy Agreement to provide
nationwide Internet dial access and related services to Prodigy for its
approximately 900,000 subscribers on the new Splitrock Network. In order to
provide Internet access services to Prodigy while the Splitrock Network was
being deployed, on July 1, 1997 the Company acquired the Legacy Network and
began immediately providing Internet dial access and related services to Prodigy
for its subscribers. Additionally, the Company uses the IBM Global Services
Network to cover market areas that are served neither by the Splitrock Network
nor the Legacy Network. The Company currently handles more than 750 million
minutes of Internet traffic per month for Prodigy (currently the Company's only
Internet dial access customer), with over 60% of the traffic flowing on the
Splitrock Network, approximately 30% on the IBM Global Services Network and the
remainder on the Legacy Network. As the Phase II Expansion progresses, Legacy
Network POPs will be decommissioned and access to specific IBM Global Services
Network POPs will be terminated when appropriate. Substantially all Legacy
Network POPs are expected to be decommissioned by the end of 1998 and usage of
the IBM Global Services Network is expected to terminate by the end of the
second quarter of 1999. In addition to providing Internet dial access and
related services to Prodigy, the Company has recently launched two new data
services, transit services and VPN services, and has begun providing transit
services to Orbis, an Internet connection service provider to businesses, and
VPN services to NetworkTwo, a value added network service provider.
 
     The Splitrock Network Architecture. The Splitrock Network, through its
ATM-to-the-edge architecture, will allow the Company to concurrently provide
multiple services such as data, video and voice to its customers and to
incorporate future technology changes at relatively low incremental investments.
As a result, the Company believes it has created a more efficient network than
its competitors, thereby reducing its own costs and concurrently improving
reliability to the end user.
 
     Communication service providers have typically provided services using two
predominant types of infrastructure, one geared towards voice service and the
other designed to optimize data communications. These infrastructures are based
on (i) telecommunications switches designed primarily for voice grade services
or (ii) data telecommunications routers and switches designed primarily for
communications between computers. Practical considerations and equipment
constraints have lead to the development of these two types of distinct network
infrastructures. Voice telecommunications service providers historically have
needed to provide a high level of reliability because of the need for life
dependent emergency services such as 911 calls. Since telephone services use
relatively simple handsets that cannot redial or re-transmit automatically if
disconnected, telephone network providers depend upon equipment reliability,
network architecture design, network management and maintenance to meet their
service needs and reliability constraints. Data telecommunications service
providers, on the other hand, have the benefit of highly intelligent terminals
at the end-user. These terminals usually can determine if a transmission error
has occurred and automatically re-transmit data and even reconnect a session if
necessary. With the help of intelligent terminals, data telecommunication
service equipment run complex routing algorithms that allow them to locate and
find the best route to transmit data. While providing a high degree of
flexibility, data telecommunication service equipment is generally plagued with
system reliability issues and often unpredictable performance. This attribute
has historically differentiated data telecommunication service equipment from
voice telecommunication service equipment.
 
     In order to create a network which efficiently supplies multiple types of
services, such as data, video and voice, a company must make the platform
reliable enough to support voice, yet flexible enough to support data. To date,
all companies successfully providing voice and data concurrently have
partitioned their network's bandwidth to support two separate service
infrastructures. Part of their bandwidth is used for voice, employing voice
telecommunications service switches, and the other part is used for data,
employing standard data telecommunication equipment in the network.
 
     Separating bandwidth use is a very practical way to provide multiple
services. Particularly today, when voice traffic still dominates the majority of
bandwidth transferred over most networks, all major networks have
 
                                       62
<PAGE>   65
 
partitioned their bandwidth into two separate components, one to carry voice and
the other to carry data. As long as data represents a small portion of network
traffic, this partitioning remains practical. However, it is expected that the
rapid growth of data will soon cause data to consume more bandwidth than voice.
When that occurs, partitioning will make network bandwidth utilization very
difficult to optimize while creating significant management complexity.
 
     The Splitrock Network was designed to address these and other constraints
facing older networks by not requiring the separation of bandwidth for different
types of services. In the process of designing the Network the Company sought to
create a Network infrastructure which could (i) efficiently offer data, video,
and voice services concurrently, (ii) reduce operating costs by more efficient
utilization of network resources and (iii) provide high quality service for all
services offered on the Network.
 
     The Company believes that three features distinguish the Splitrock Network
from other telecommunications networks. First, Splitrock uses the Lucent LDR200
switch which supports multiple services at every POP of the Network. The Company
believes that this "intelligent" ATM switch differs from typical ATM backbone
switch engines in two important ways. First, the Lucent LDR200 supports many
access protocols to the Network whereby an array of data, video and voice
services can be sent and/or received, such as IP, frame relay, ATM, ethernet,
T-1, T-3, OC-3 and many other digital as well as analog interfaces. The Lucent
LDR200 is also scalable with up to fourteen interface module slots designed to
house interface cards supporting these various services. The Lucent LDR200
translates these native service protocols into standard ATM format and
transports any service as an ATM connection. In addition, the Lucent LDR200
implements a patented queuing algorithm, allowing simultaneous support of data,
video and voice services on a unified platform without loss of quality of
service even during periods of high network utilization. The queuing algorithm
eliminates the need for bandwidth allocation to different kinds of services.
 
     Second, to manage the large number of ATM switches in the Network, the
Company organized the Network architecture into classes and regions. This
architecture allows the Company to more quickly introduce new services because
all new services can be layered on the Network's ATM switching fabric without
alterations being made to the fabric itself. A new network service has two
components, the protocol that defines the format of the information payload and
the signaling or routing instructions required to direct the information to its
destination in the network. The Splitrock Network ATM switching platform
streamlines the signaling process because routing information is concentrated in
a limited number of central sites in the Network (known as core sites) rather
than having signaling or routing information interpreted by switches or routers
at every point of the network as occurs, for example, in a typical IP-based
network. Therefore, to introduce a new service, the Company only needs to deploy
the proper signaling or routing processors at a few core sites instead of
hundreds of switch or router sites distributed around the network. This reduced
number of routing decisions also allows for better management and typically
faster throughput than other networks.
 
     Third, most modern networks achieve transmission efficiencies by deploying
ATM switching engines in three to twenty access sites only in the core backbone
of their network. In contrast, Splitrock has created an ATM-to-the-edge
switching fabric that blankets the entire network (i.e., ATM switches are
located in all POPs throughout the Splitrock Network). As of June 1, 1998,
Splitrock had installed 70 ATM switches, and expects to deploy an additional 330
ATM switches during the Phase II Expansion. ATM-to-the-edge forms the basic
platform for Splitrock to offer multiple services to all users on the Network.
 
     The Splitrock Network is organized into three classes of access sites: core
sites, hub sites and remote sites. The architecture partitions the entire
Network into 21 regions, with a core site in each region. The core site is
generally located in the city with the most traffic in that region. Users access
the Network within a region by connecting to either a core, a hub or a remote
access site. The core sites form the backbone of the Splitrock Network, with the
hub and remote access sites extending the reach of the backbone.
 
                                       63

     The following diagram is a simplified illustration of the Company's
ATM-to-the-edge Network architecture, and is designed for illustrative purposes
only. It does not represent the actual number or location of POPs.
 
                         [NETWORK ARCHITECTURE GRAPHIC]
 
     The 21 core sites, all of which were completed by June 1, 1998, are
equipped with Lucent LDR200 switches. Using ATM technology, these core sites are
logically fully meshed, allowing traffic to pass directly from any one region to
any other region. The core sites are interconnected by standard transmission
links such as DS-3 or OC-3, which are available from IXCs such as WorldCom, MCI
and Qwest Communications International Inc. ("Qwest"). Because the Lucent LDR200
conforms to standard transmission specifications, the Company can purchase
bandwidth on an actual need basis between each site and upgrade these links as
the bandwidth demand increases.
 
     In addition, each core site is equipped with special protocol processors to
enable the Network to accommodate demand for a wide variety of services. For
example, to support IP protocol for Internet services, standard Cisco IP routers
are installed, one per core site. These are the only routers installed in the
Network as opposed to other networks which have routers installed throughout the
network. Since a router has direct connections to every other router in the
Splitrock Network, the routers have very simple routing tables and can forward
packets from region to region efficiently and directly.
 
     Hub sites service the major cities within a region. Upon completion of the
Network expansion, there will be approximately 60 hub sites in the Network, of
which 49 were completed by June 1, 1998. Each hub site is equipped with a Lucent
LDR200 switch and all other user access equipment, including Bay Network modems,
necessary for Internet dial access service. A Splitrock user connected to any
hub site can access the complete array of services. Hub sites connect to core
sites over a DS-3 line or multiple T-1 lines depending on the traffic
requirements. Hub sites can be connected redundantly to other hub sites or to
other core sites to increase network reliability. For IP traffic, all packets
from a hub site are forwarded directly to the region's core site, and then
forwarded to their destination region by the core site router.
 
     Upon completion of the Phase II Expansion, the Network will have more than
300 remote sites to reach the smaller cities within a region. None of such sites
were in place by June 1, 1998. These sites are also fully equipped with Lucent
LDR200 switches and other equipment to allow user access to the same services as
elsewhere in the Network. Remote access sites connect to a hub site, usually
with a T-1 line. The remote sites
 
                                       64
<PAGE>   67
 
can also be protected from transmission failures by being connected redundantly
to other access or hub sites in the region. The Company has not added a material
number of POPs since June 1, 1998.
 
     The following diagram is a simplified illustration of how the Splitrock
Network is designed to deliver data (including Internet), video and voice
services.
 
                                  [FLOW CHART
 
     Network Infrastructure. The Company believes that it has provided for
future growth by ensuring that the Splitrock Network is scalable, flexible,
fault tolerant, open standards and interoperable and manageable from remote
locations.
 
     - Scalable. Splitrock's flexible, multi-layer network architecture utilizes
       a high-speed switching fabric enabling the Company to grow the number of
       POPs and the number of users served in an incremental manner that matches
       investment with demand. The Splitrock Network's scalability extends
       beyond the currently installed base of POPs to allow for growth without
       fundamental design changes.
 
     - Flexible. The Company believes that the Splitrock Network will adapt to
       new services and manages network resources according to each service's
       needs, permitting the Network to efficiently offer data, video and voice
       services concurrently. On the switching level, the switching elements
       (Lucent LDR200 switches) adjust Network responses based on the traffic's
       delay and loss sensitivities. On the protocol level, the Network
       architecture is able to sort and direct various protocols to its
       designated protocol processors, including Internet packets to Cisco
       routers, ISDN signaling to workstations with ISDN software, and
       traditional voice network signaling to workstations with SS7 software.
 
     - Fault Tolerant. Redundancy and adaptive technology in the Splitrock
       Network reduces the impact of isolated failures. For example, all core
       sites are interconnected, allowing traffic to be transferred among sites
       in case of a failure. In addition, key switching, routers and
       workstations are configured to search for alternate paths in the event of
       individual component or transmission line failure. The Company also has
       an uninterruptible power supply at each POP, limiting the impact of local
       power outages on the Network.
 
     - Open Standards and Interoperable. The Splitrock Network is entirely based
       on standards compliant architecture supporting various protocols,
       including IP, ATM, frame relay, ISDN video and SS7. This architecture
       allows Splitrock to interconnect freely with other carrier networks or
       customer networks. As a result, Splitrock can extend services of another
       carrier outside of that carrier's own region. In addition, potential VPN
       clients that use standards based protocols can easily access the Network
                                       65
<PAGE>   68
 
       without having to purchase special equipment that would otherwise be
       necessary with a proprietary network.
 
     - Manageable. From its NOCs, the Company is able to monitor the Network
       remotely, perform network diagnostics and equipment surveillance, and
       inform customers when a network problem occurs. As a result of the
       Company's network architecture, these tasks may be performed remotely
       regardless of POP location or network status. This capability allows the
       Company to control costs associated with on-site network configuration
       and repair.
 
     Network Management. The Company believes that superior customer service is
a critical element in attracting and retaining customers, and expanding value
added services to existing customers. In particular, the Company believes it is
critical to maintain two geographically dispersed NOCs, each of which is able to
monitor the entire Network and provide rapid problem resolution. The Company has
established a 24-hours per day, seven days per week NOC at its Yorktown, NY
facility. In addition, a new 24-hours per day, seven days per week NOC recently
became fully operational at The Woodlands, TX facility.
 
     Peering. Peering arrangements between the Company and ISPs are necessary to
exchange traffic destined for other networks and to allow external traffic
access to the Splitrock Network. With Prodigy as a customer, the Company is now
carrying a significant amount of Internet traffic. The Company is building an
infrastructure equivalent to other Tier 1 providers and it has sought peering
relationships with many Tier 1 and Tier 2 ISPs. Peering arrangements have been
established with six ISPs, including Sprint and PSINet, and the Company is
currently in discussions with other ISPs in order to broaden its peering
capabilities. The Company peers with other networks from a core site through an
industrial standard Cisco router, which promotes proper protocol exchange
between Splitrock and other ISPs. The Company currently maintains private
peering connections at its Los Angeles, California; New York, New York; Atlanta,
Georgia; Phoenix, Arizona; and Dallas, Texas facilities. In addition, the
Company currently has access to one public peering location in Chicago, Illinois
and expects that access to two additional public peering locations will be
established in the third quarter of 1998. The Company expects that it will
substantially increase the number of ISPs with which it peers over the next two
years. The Company believes that by entering into direct peering relationships
with a large number of ISPs, the Company's business customers receive better
service and higher quality network performance. See "Risk Factors Establishment
and Maintenance of Transmission Services and Peering Relationships."
 
     Transmission Services. The Company leases long distance connections of
various bandwidths to connect sites in the Network. The choice of long distance
carriers is based on their network reliability, bandwidth availability,
responsiveness and pricing. The Company currently leases a majority of its long
distance connections from WorldCom and is also reviewing other suppliers such as
Sprint and Qwest.
 
     The Company leases local connections (DS-1, T-1 or ISDN PRI) to access the
end-user. The local service providers are selected based on their reliability,
service availability, responsiveness, pricing and minimum switch congestion
during busy hours. Based on these criteria, the Company has relationships with
21 CLECs and all major ILECs in the country. The Company has also established
approximately 60 collocations with various CLECs.
 
PRODUCTS AND SERVICES
 
     General. The pervasive deployment of ATM switching technology throughout
the Network enables the Company to offer new services with lower incremental
investment than that required by less flexible networks. Currently, the Company
provides Internet access options and related-services, including Internet dial
access services and transit services, as well as enhanced VPN services. The
Company is seeking to increase total network utilization primarily by targeting
providers of business services (daytime intensive traffic) and, to a lesser
extent, providers of consumer services (evening intensive traffic).
 
                                       66
<PAGE>   69
 
     Internet Access Options. The Company provides the following Internet access
options and related services to its customers:
 
     - Internet Dial Access Services. The Company's Internet dial access
       services offer a cost effective Internet solution that provides 56k dial
       access to the Company's advanced ATM-to-the-edge network via ordinary
       telephone lines. The Company's Internet dial access services provide
       smaller ISPs with the opportunity to increase their user base over time
       while at the same time providing larger ISPs the opportunity to cost
       effectively manage their growth. The Company currently provides Internet
       dial access services to Prodigy for its approximately 900,000
       subscribers. The Company intends to primarily target business focused
       ISPs and businesses and, to a lesser extent, ISPs with residential
       customers to maximize traffic throughout the Network. As of June 29,
       1998, Prodigy was the Company's only Internet dial access service
       customer.
 
     - Transit Service. The Company offers high speed transit services, which
       provide businesses with direct access, via dedicated capacity, to a full
       range of Internet applications and allows an ISP to transfer traffic
       through the Company's Network to another ISP. The Company's transit
       services provide full-time dedicated Internet connectivity at a range of
       access speeds from 56 Kbps to 155 Mbps. This service is designed to offer
       comprehensive network security and to help ensure bandwidth availability
       for priority business applications. Transit services enable businesses to
       reduce their data communications expenses by leasing network utilization
       from the Company in lieu of leasing point-to-point circuits from other
       telecommunications providers. The Company has initially begun to target
       carriers (i.e. ISPs, ILECs, CLECs, regional long distance providers and
       wireless providers) as potential customers for this service. As the
       Company's carrier transit service business grows, the Company will target
       other businesses. Since May 1998, the Company has provided transit
       services on a month-to-month basis to Orbis, an Internet connection
       service provider to businesses, which is currently the Company's only
       transit service customer.
 
     Virtual Private Network Services. Many companies today have private data
communication networks (often referred to as WANs) built on expensive leased
lines designed to transfer proprietary data between office locations. The
Splitrock Network offers companies a cost-effective alternative to WANs through
VPNs, which are designed to provide secure transmission of private IP traffic
through the Internet. Additionally, many companies require that their employees
have remote access to these private networks from home or while traveling, which
is a function that VPNs provide. VPN products are also the vehicle for offering
intranet and extranet services. Intranets are corporate/organizational networks
that rely on Internet-based technologies to provide secure links between
corporate offices. Extranets expand the network to selected business partners
through secured links on the Internet. Increasingly, companies are finding that
intranets and extranets can enhance corporate productivity more easily and less
expensively than proprietary systems. The Company currently offers VPN
solutions, and is in the process of evaluating additional products to meet the
needs of customers. For example, the Company is in the process of testing ISDN
software and expects to offer video conferencing services to customers by
September 1998. Such services will be point-to-point, targeted primarily at the
communications needs of companies using PictureTel, VTEL or other standards
based video conferencing, and will allow the business customer to conduct video
conferencing with other on-network or off-network users with compatible video
conferencing equipment. The Company has initially begun to target carriers (e.g.
ISPs, ILECs, CLECs, regional long distance providers and wireless providers),
which the Company expects to distribute the Company's VPN services to end-users.
As the Company's VPN service business grows, the Company will also target
businesses as potential VPN customers. The Company has signed an agreement with
NetworkTwo, a value added network service provider, and began delivering VPN
services pursuant to this agreement in June 1998. NetworkTwo is currently the
Company's only VPN customer.
 
DISTRIBUTION STRATEGY
 
     Through the combination of a direct sales force and alternative
distribution channels, the Company believes that it will be able to access
markets and increase revenue-producing traffic on the Splitrock Network. To
implement its distribution strategy, the Company intends to develop an in-house
direct sales force and has
                                       67
<PAGE>   70
 
identified a variety of possible alternative distribution channels. The Company
expects to begin hiring sales employees in the second half of 1998.
 
     The Company intends to utilize its direct sales force to market its
products and services directly to ISPs, carriers, value added service providers
and medium and large businesses. The Company intends to utilize alternate
distribution channels to market its products and services to medium and small
businesses. These alternate distribution channels include agents, resellers and
wholesalers.
 
     - Agents are independent organizations that would sell the Company's
       products and services under the Splitrock brand name to end-users in
       exchange for revenue based commissions. The Company intends to identify
       agents that generally would be focused on specific market segments (such
       as medium and small businesses) and have existing customer bases. Sales
       through this alternative distribution channel would require the Company
       to provide the same type of services that would be provided in the case
       of sales through its own direct sales force, such as order fulfillment,
       billing and collections, customer service and direct sales management.
 
     - Resellers are independent companies that would purchase the Company's
       products and services and then "repackage" these services for sale to
       their customers under their own brand name. The Company believes that
       resellers would require access to certain of the Company's business
       operating systems in connection with the sale of the Company's services
       to the resellers' customers. Sales through this distribution channel
       generally would not require the Company to provide order fulfillment,
       billing and collection and customer service.
 
     - Wholesalers are independent companies that would purchase from the
       Company unbundled network and service capabilities in large quantities in
       order to market their own products and services under a brand name other
       than Splitrock. The Company believes that wholesalers would have minimal
       dependence on the Company's business support systems in connection with
       the sale of services to their customers.
 
     The Company anticipates that participants in its alternative distribution
channels will sell services directly to medium and small businesses. The Company
expects these medium and small businesses to access the Splitrock Network by
using local switched services that are provided by CLECs or ILECs.
 
CUSTOMERS
 
     The Company currently provides Internet dial access, transit and VPN
services to its customers. To date, Internet dial access services have provided
substantially all of the Company's revenue. The Company expects this percentage
to decrease as the Company continues to add new customers.
 
     Internet dial access customers. Prodigy has been the Company's customer
since July 1997 and has provided substantially all of the Company's revenue
since its inception. Launched in 1984 as a joint venture between IBM and Sears,
Prodigy developed a nationwide on-line service that reached more than 85% of
U.S. households with a local call. Along with America Online, Inc. and
CompuServe Corp., Prodigy helped pioneer the concept of e-mail and on-line
services to consumers in the U.S.
 
     In 1996, Prodigy was spun off from IBM and Sears. In 1997, Carso obtained
control of Prodigy. Carso introduced a new management team which has focused on
growing and expanding the business, modernizing infrastructure, and reducing
costs. In early 1997, Prodigy launched a new Internet-based service, Prodigy
Internet, separate from the original proprietary on-line service, Prodigy
Classic, priced at $19.95 per month for unlimited service. Prodigy is in the
process of migrating Prodigy Classic subscribers to Prodigy Internet. During the
first quarter of 1998 the average number of total Prodigy Internet subscribers
grew 36.4% compared to the fourth quarter of 1997, in part as a result of a
migration of Prodigy Classic subscribers to Prodigy Internet. The Company does
not expect this rate of growth to continue in the second quarter of 1998. In
September 1997, PC Magazine selected Prodigy as its Editor's Choice for Internet
service.
 
     In 1998, as a result of its continued focus on marketing and customer
service, Prodigy outsourced its content management to Excite Communications,
Inc. Additionally, Prodigy has started aggressive marketing
                                       68

programs which are intended to rebuild its brand name recognition. Since July
1997, Prodigy has almost doubled the number of subscribers to its Prodigy
Internet service partially as a result of a migration of Prodigy Classic
subscribers to Prodigy Internet. The Prodigy customer base and associated
revenue has enabled the Company to support the deployment of the Splitrock
Network. See "Risk Factors -- Reliance on Prodigy; Recent Discussions with
Prodigy."
 
     Transit customers. There are approximately 4,000 ISPs in the U.S. today.
Most of these do not have their own nationwide network and thus require transit
service to the Internet. Commencing in May 1998, the Company has provided
transit services to Orbis on a month-to-month basis. Orbis is the leading
provider of local Internet connection services for businesses in Minneapolis and
St. Paul, Minnesota. Orbis offers business critical connectivity featuring
redundant, high-speed (T-1, T-3) backbone connections, 24-hour operational and
environmental monitoring, and Web hosting services. At the beginning of each
month, Orbis requests a certain amount of dedicated bandwidth and the Company
then charges a monthly fee based on the amount of bandwidth requested. The
Company began generating revenues from Orbis in May 1998. The Company does not
expect that revenues from Orbis will be material for the foreseeable future.
 
     VPN customers. The Company has entered into a three-year agreement to
provide VPN services to NetworkTwo. NetworkTwo, formerly known as ADP AutoNet
Communications Group, supplies high quality, reliable and fully supported
network services and operates a national wide area network delivering both
dedicated and dial-up connectivity to business clients. NetworkTwo also manages
VPNs, enterprise-wide intranets and extranets. NetworkTwo moves more than $2.0
billion over its network each day as a function of its cash management and funds
transfer service for ADP Financial Services. Other Network Two users include Dow
Jones' News Retrieval service; State Farm and Allstate insurance companies; and
60 of the top 100 U.S. banks. Under the agreement, NetworkTwo will be billed
depending on the type of modem port used (i.e. 612 Kbps, 768 Kbps, etc.) and the
amount of bandwidth consumed, with certain discounts available based on volume.
The agreement provides for a minimum aggregate payment by NetworkTwo of $7.0
million over the three year contract period. The Company began generating
revenue from NetworkTwo in June 1998.
 
CUSTOMER SERVICE
 
     Splitrock believes that superior customer service is a critical element in
attracting and retaining customers and expanding value added services to
existing customers. In particular, the Company believes it is critical to
maintain two geographically dispersed NOCs, each of which is able to monitor the
entire Network and provide rapid problem resolution. Since the first quarter of
1998, the Company believes that it has developed a customer service platform
which will minimize the impact of future service interruptions and provide
superior customer service. Specifically, the Company has established a 24-hours
per day, seven days per week NOC at its Yorktown, NY facility and a new 24-hours
per day, seven days per week NOC recently became fully operational at The
Woodlands, TX facility. Each of these NOCs has the capability to manage traffic,
monitor system status and remotely implement solutions to system interruptions.
 
     As of May 1998, the Company had implemented a number of other systems and
procedures to provide superior customer service. The Company has installed a
leading customer support trouble ticketing and workflow management system from
Remedy Corporation ("Remedy") to track, route and report on customer service
issues. In addition, software installed at the NOCs now enables the Company to
remotely service customer connections to the Splitrock Network. In addition,
field service personnel from the Company or third party vendors are dispatched
in the event of an equipment failure that cannot be serviced remotely. See
"-- Suppliers." In the first quarter of 1998 the Network experienced significant
service interruptions and failures. See "Risk Factors -- Reliance on Prodigy;
Recent Discussions with Prodigy."
 
BUSINESS SUPPORT SYSTEMS
 
     General. Through the development of scalable business support systems, the
Company believes that it has the opportunity to establish a competitive
advantage relative to traditional network service providers. Traditional network
service providers typically operate extensive legacy business support systems
with compartmentalized architectures that limit their ability to scale rapidly
and introduce enhanced services and
 
                                       69
<PAGE>   72
 
features. In connection with the expansion of the Splitrock Network, the Company
is creating business support systems with an architecture designed to maximize
both reliability and scalability. Furthermore, in establishing its business
support systems, the Company has attempted to develop Company-wide
standardization of hardware, software, database platforms and problem solving in
order to maximize system automation and minimize employee manual processing.
Business support systems are, or will be, distributed throughout the Splitrock
Network, rather than located at central sites, which improves network
performance, recovery and reliability, while also providing real-time capture of
statistical and accounting data. Splitrock utilizes, when available, industry
standard software systems developed and maintained by third party vendors but
customized for the Company's specific needs.
 
     Network Management. The Company believes that an up-to-date management
platform is critical for the Company to be competitive and provide customers
with quality services. The Company has put in place a modern management platform
to manage the extensive Splitrock Network. The new management platform performs
operations, administration and management tasks. The Company has selected UNIX
and Windows NT based computing systems for network management to ensure ease of
upgrades in the future. Key features of the system are provided by third party
vendors, including an SQL database for information management, NetExpert from
Objective Systems, Inc. for equipment monitoring, Remedy for trouble request
tracking, and other software running tasks that monitor network utilization. The
Company has customized most of these platforms to ensure maximum Network
flexibility and efficiency. The systems also have sufficient capacity to expand
without significant design changes.
 
     Billing. The Company is reviewing billing systems and will select an
industry-standard billing system and begin implementation in the third quarter
of 1998. The Company believes that billing requirements prior to full
implementation, expected in the fourth quarter of 1998, can be addressed with
existing systems. In order to augment the third party system that the Company
plans to utilize, the Company has adopted Radius Authentication software to
capture Internet session activity in order to feed the billing system for
usage-based services. The Company believes that this system offers the
flexibility and scalability necessarily to provide high quality Network billing
services. For example, the Company believes that this system will have the
ability to process 1 million records per hour to capture all relevant billing
information. While this system has been purchased and customized, it has yet to
be tested at production levels but is expected to be fully deployed by the end
of August 1998.
 
SUPPLIERS
 
     The Company is dependent on third parties for key components of its network
infrastructure, including for leased lines, transmission services and networking
equipment, such as routers, switches and modems. The quantities and quality of
such networking equipment required by the Company are available only from
limited sources. The Company currently utilizes Lucent for ATM switching
products, including the Lucent LDR200 switch, Bay Networks for its Internet dial
access platform, Cisco for routers and Sun for servers. The Company has entered
into a Purchase Agreement with Yurie (which was acquired by Lucent in May 1998)
pursuant to which the Company agreed to purchase and Yurie agreed to provide a
minimum of $20.0 million of Yurie equipment and related products prior to
January 1, 1999. As of July 15, 1998 the Company had purchased $11.0 million of
equipment and products under this agreement. The Company also depends upon a
variety of LECs and IXCs to provide telecommunication services, including leased
line and collocation facilities. For long distance connections and backbone long
distance transmission facilities, the Company currently uses WorldCom. In
addition, the Company obtains bandwidth capacity under leased line connection
agreements with LECs, including RBOCs, or is provided telecommunications
services and leased physical space under local access/collocation agreements
with various CLECs, such as Focal, Intermedia, and others. The Company is also
actively pursuing agreements with additional CLECs in an effort to establish
relationships with a variety of telecommunication providers and thereby reduce
the cost of lease connectivity. See "Risk Factors -- Dependence on Suppliers"
and "-- Splitrock's Network -- Transmission Services."
 
     The Company has an agreement with IBM to use the IBM Global Services
Network to cover market areas that are neither served by the Splitrock Network
nor the Legacy Network. These POPs currently account for approximately 30% of
all Prodigy-related traffic. The terms of the agreement provide that either
                                       70
<PAGE>   73
 
party may, upon 60 days prior notice, terminate its respective obligations under
the contract for the remaining POP sites. In addition, under the terms of the
agreement with IBM, services at certain of the POPs in the IBM Global Services
Network are scheduled to be discontinued on September 30, 1998. These POPs
currently represent less than 2% of the Company's Prodigy-related traffic. As
part of the Phase II Expansion, the Company plans to deploy POPs to those
locations. The Company has also formulated contingency plans, including
providing toll free Internet dial access to users in these areas, should the
Company be unable to timely deploy POPs in those areas or IBM be unwilling to
continue to provide service to those POPs after September 30, 1998. See "Risk
Factors -- Dependence on Suppliers."
 
     As part of the Company's strategy to replace remaining POPs covered by the
IBM Global Services Network and to complete the expansion of the Splitrock
Network, the Company will rely significantly upon third parties to provide
equipment and services and to deploy the remainder of the Splitrock Network.
Under the Ericsson Agreement, Ericsson will provide certain equipment and
services for, and deploy, 99 additional POP sites. In connection with this
agreement, Ericsson has provided the Company with a $5.0 million credit facility
to be used to pay amounts due under the Ericsson Agreement, which was repaid
upon consummation of the Unit Offering. The Company is in negotiations with
Ericsson for the deployment of the additional 231 POPs needed to complete the
Phase II Expansion. The Company expects that such negotiations will lead to an
agreement on similar terms and conditions as the Ericsson Agreement. There can
be no assurance that the Company and Ericsson will come to an agreement on the
deployment of the remaining 231 POPs required to complete the Network's
expansion. See "Risk Factors -- Suppliers" and "Description of Certain
Indebtedness."
 
     The Company also engages third party vendors for routine maintenance,
on-call repair and certain related services. In addition to nine employees and
six individual contractors designated, trained and engaged by the Company as
field operation personnel, the Company has an agreement with IBM designed to
provide additional on-call field support personnel for maintenance, part
replacement and repairs for the Legacy Network until that network is
substantially decommissioned. In addition, during and following the Phase I
Buildout, WilTel has performed on-call services for replacement parts,
maintenance and repair services for the Splitrock Network. The agreement with
WilTel will expire on September 30, 1998. The Company is currently evaluating
and negotiating maintenance service proposals that are designed to replace the
agreements with IBM and WilTel and expand as the network infrastructure grows.
There can be no assurance that the Company will be able to enter into a
replacement maintenance agreement on acceptable terms, or at all. See "Risk
Factors -- Dependence on Suppliers."
 
COMPETITION
 
     The industry in which the Company competes is extremely competitive. The
Company expects that competition will continue to intensify as customers seek
additional capacity to satisfy the continued growth of the Internet industry. In
addition, numerous competitors, including major telecommunications carriers, are
rapidly expanding their network capabilities. The Company believes that the
primary competitive factors for the provision of network services are quality of
service, network coverage, reliability, price, and product innovation.
Management believes it can compete effectively on these factors based on the
design of the Splitrock Network and industry experience at top management
levels.
 
     The Company's current and prospective competitors generally may be divided
into two groups: (i) companies that provide Internet access services to ISPs
with both residential and small business customers and (ii) companies that
provide Internet access (including Internet dial access and transit), VPN and
other value added services to medium and large business customers.
 
     ISP Internet Access Service. According to IDC, there are over 4,000 ISPs in
the United States, consisting of national, regional and local providers. The
Company intends to market Internet dial access services to these ISPs. The
Company's competitors in this market will be other companies that provide
Internet access service to ISPs as well as ISPs which possess backbone networks
thereby enabling them to provide capacity to other ISPs. Competitors in this
segment include Verio, Concentric, PSINet and Netcom. While the Company believes
that its status as an independent service provider distinguishes it from many of
 
                                       71
<PAGE>   74
 
these competitors, some of these competitors have significantly greater market
presence, brand recognition and financial, technical and personnel resources
than the Company.
 
     Corporate Internet Access and VPN. In the corporate Internet access
(including Internet dial access and transit) and VPN markets, competitors will
be comprised of network service providers that focus on medium and large
business customers as well as telecommunications carriers. Competitors will
include UUNet, GTE Internetworking (formally BBN)) and DIGEX. Many of the
network service providers that primarily focus on small business, including
Verio and Concentric, also have capabilities in these markets. In addition, all
of the major long distance companies, including AT&T Corporation ("AT&T"), MCI,
and Sprint, offer Internet access and VPN services and compete with the Company.
Many of these competitors, in addition to their substantially greater market
presence and financial, technical and personnel resources, also have large
existing commercial customer bases. Furthermore, many of these competitors have
the ability to bundle Internet access and VPN services with other services such
as Web browsing or, in the case of long distance companies, telephony. Such
bundling of services may have a material adverse effect on the Company's ability
to compete effectively and thus could have an adverse effect on the Company's
business, financial condition and results of operations.
 
     The Company believes that significant new competitors will enter the
network services market. The Company is aware that other companies, including
IXC Comm. and Level 3, are in the process of building or expanding networks that
will have the ability to provide services comparable to those of the Company. In
addition, many of the Company's competitors have the financial and operational
resources to construct networks similar to the Splitrock Network. For example,
Sprint recently announced that it is in the process of designing a network which
will contain ATM switches at every core, hub and remote site. There can be no
assurance that the Company will be able to compete effectively with such
companies.
 
     Recent reforms in the federal regulation of the telecommunications industry
have also created greater opportunities for LECs, including the RBOCs, to enter
the Internet network services market and therefore compete with the Company.
Such increased competition could have a material adverse effect on the Company.
In order to address the Internet network service requirements of the current
business customers of long distance and local carriers, the Company believes
that there is a trend toward horizontal integration through acquisitions of,
joint ventures with, and the wholesale purchase of connectivity from, ISPs. The
WorldCom/MFS/UUNet consolidation (as well as the pending WorldCom/ MCI merger),
the Netcom/ ICG Communications Inc. merger, the Intermedia/DIGEX merger and
GTE's acquisition of BBN are indicative of this trend. Such consolidations may
result in the Company competing with larger companies with greater resources to
devote to the development of new competitive products and services and the
marketing of existing competitive products and services.
 
     As a result of increased competition and integration in the industry, the
Company could encounter significant pricing pressure, which in turn could result
in significantly lower average selling prices of the Company's services. There
can be no assurance that the Company will be able to offset the effects of any
such lower prices with an increase in the number of its customers, growth in
sales to its customer base, higher revenue from enhanced services, cost
reductions or otherwise. In addition, the Company believes that the Internet
access and related services industry is likely to undergo further consolidation
in the near future, which could result in increased price and other competition
in these industries and, potentially, other portions of the industry, including
the market for VPN services. Increased price or other competition could have a
material adverse effect on the Company's business, financial condition and
results of operations. There can be no assurance that the Company will have the
financial resources, technical expertise or marketing and support capabilities
to continue to compete successfully.
 
REGULATION
 
     Overview. Although the Company is not currently subject to direct
regulation by the FCC or any other federal or state agency, it operates in a
highly regulated industry and therefore changes in the regulatory environment
relating to Internet related and other telecommunications services, including
regulatory changes which directly or indirectly affect telecommunications costs
or increase the likelihood or scope of competition
 
                                       72
<PAGE>   75
 
from RBOCs or other telecommunication companies, could have a material adverse
effect on the Company's financial position or results of operations, including
by affecting the prices at which the Company offers it services or imposing
regulatory compliance and other costs on the Company.
 
     Various existing federal and state regulations are currently the subject of
judicial proceedings, legislative hearings and administrative proposals which
could change, in varying degrees, the manner in which the industry operates.
Neither the outcome of these proceedings, nor their impact upon the
telecommunications industry generally, or on the Company particularly, can be
predicted at this time. In addition, over the past several years both the
federal and state governments have adopted new legislation and rules profoundly
affecting the telecommunications industry. No assurance can be given that the
changes in current legislation or new legislation, and the regulations adopted
by the FCC or state regulators pursuant to such legislation, would not have a
material adverse impact on the Company.
 
     The Company Operates as an Unregulated Private Carrier. Unlike most
providers of telecommunications services, the Company does not offer services
indiscriminately to the public or to a broad class of customers, but instead
negotiates individual service contracts with a small number of select carriers.
As a result, it is classified as a "private carrier" as opposed to a "common
carrier" and is not subject to most federal and state regulations. If, in the
future, the Company broadens its customer base and/or provides services
according to standardized service arrangements instead of individually
negotiated contracts, it may become subject to common carrier regulation. If
this occurs, the Company may incur additional regulatory costs to which it is
not now subject.
 
     Regulation of Internet Communications. To date, the FCC has exempted
Enhanced Service Providers ("ESPs"), including ISPs, from federal and state
regulations governing common carriers, including the obligation to pay access
charges and regulatory fees, including contributions to the Universal Services
Fund. Thus, to the extent that the Company provides Internet services and other
services employing Internet protocols, it is not currently subject to
regulation.
 
     Some recent regulatory action indicates that ISPs may be subject to some
form of regulation in the future. The regulatory status of communications
services over the Internet is presently uncertain. For example, in an April 10,
1998 Report to Congress regarding Universal Service (the "Report"), the FCC
concluded that the provision of transmission capacity to ISPs constitutes
"telecommunications" under the Communications Act. The FCC has also indicated in
the Report that it would consider, in an upcoming proceeding, issues related to
whether ISPs that own transmission facilities and engage in data transport over
those facilities in order to provide information services are providing
telecommunications to themselves, and therefore ought to be required to
contribute to the Universal Service Fund. While the Report containing this
conclusion does not have the force of law, it provides a strong indication of
regulatory action that may be taken by the FCC in the future. A finding by the
FCC that ISPs and carriers providing service to ISPs must pay Universal Service
contributions could increase the Company's cost of doing business and have a
material adverse affect on the Company.
 
     To the extent that the Company provides Internet telephony (i.e., a service
in which a voice transmission is made over a packet-switched interactive data
network), such service is deemed an enhanced service and is not currently
subject to federal or state regulation. There is no guarantee, however, that the
regulatory status of Internet telephony will not change in the future. If
Internet telephony does become subject to federal or state regulation in the
future, such a development could impose substantial new costs on the Company.
Therefore, there can be no assurance that new laws or regulations relating to
these services, or determinations that existing laws are applicable to them,
will not have a material adverse effect on the Company's business.
 
     Potential Liability of ISPs. The law in the United States relating to the
liability of ISPs and providers of transmission capacity for information carried
on, disseminated through or hosted on their systems is currently unsettled. The
Communications Act and statutes enacted, or under consideration in some states,
impose civil and criminal liability upon ISPs, or providers of transmission
capacity to ISPs, for the transmission or dissemination of certain types of
information and materials. The imposition of such liability may require the
Company to implement measures to reduce its exposure to such liability, which
may require the expenditure of substantial resources. Regulations, litigation,
or legislation could affect the demand for the Company's
                                       73

services. See "Risk Factors Regulatory Matters; Potential Liability for
Information Disseminated over the Internet."
 
TRADEMARKS AND TRADE NAMES
 
     The Company filed federal trademark applications for the words "Splitrock"
and "A Carrier of Wisdom" on September 18, 1997, and its domain name
"splitrock.net" on March 6, 1998. The Company also filed separate federal
trademark applications for logos on the above dates, and for a logo on June 16,
1998. These applications are pending and the Company has no assurance that they
will be granted. Trademark applications for the "Splitrock" mark also have been
applied for in numerous foreign countries including Mexico, twelve Central and
South American countries, Canada, the European Community, Japan, South Korea,
Taiwan, China, Thailand, the Russian Federation, Poland and Australia.
"Splitrock Services, Inc." is a trade name of the Company.
 
EMPLOYEES
 
     As of July 15, 1998, the Company had 74 full-time employees and 24
independent contract workers. None of the Company's employees are represented by
a union. The Company has experienced no strikes or work stoppages and considers
its relations with its employees to be satisfactory.
 
     The Company believes that its ability to successfully implement its
business strategies will depend on its ability to attract and retain qualified
employees. The Company expects to hire approximately 30 and 75 additional
employees by the end of 1998 and the Phase II Expansion, respectively. In
addition, the Company expects to utilize additional independent contractors.
Independent contractors are expected to continue to represent approximately
20-25% of the Company's total workforce. While the Company is expecting to add
employees throughout its organization, the Company will focus on recruiting new
technical and sales and marketing employees. The Company expects to employ over
175 employees and independent contractors upon completion of the Phase II
Expansion in the second quarter of 1999. In order to attract and retain highly
qualified employees, the Company believes that it is important to provide a
competitive compensation program that aligns employees' interests with the
Company's. The Company's noncash benefit programs are designed to be comparable
to those offered by its competitors. See "Management." There can be no assurance
that the Company will be able to attract and retain the personnel necessary to
implement its strategies. See "Risk Factors -- Ability to Manage Growth".
 
INSURANCE
 
     The Company has insurance coverage it believes to be adequate for the risks
of the businesses in which it is engaged. The Company carries property, general
liability and directors and officers insurance with basic policy limitations of
$5.0 million, $2.0 million and $5.0 million, respectively, subject to
deductibles, exclusions and self-insurance retention amounts. In addition, the
Company has a $5.0 million umbrella policy. Such coverage may not be adequate or
available to compensate the Company for all losses that may occur. The
occurrence of a significant loss not fully covered by insurance could have a
material adverse effect on the Company. See "Risk Factors -- Risk of System
Failure; Insurance."
 
PROPERTIES
 
     Until recently the Company leased approximately 8,000 square feet of space
in The Woodlands, TX for its headquarters and administrative facilities. In
early July 1998 the Company moved its headquarters and administrative facilities
to a new facility containing approximately 25,000 square feet in The Woodlands,
TX. The lease on the new facility expires in 2003. The Woodlands, TX NOC is also
housed in the new facility.
 
     The Company also subleases from Prodigy a facility of approximately 12,500
square feet in Yorktown, NY for the Company's Yorktown office and NOC. This
lease expires on February 28, 2001 but is subject to early termination on
December 31, 1999 upon three months written notice. The Company plans to move
its Yorktown, NY facility to another location in the New York metropolitan area.
 
                                       74
<PAGE>   77
 
     In connection with its network operations, the Company leases space for
installed telecommunications equipment throughout the U.S. for those POPs
deployed in over 70 metropolitan markets. These leases have an average term of
three years and average monthly payments ranging up to several thousand dollars.
In many cases, the Company has the option to renew such leases. The Company
considers these facilities and properties to be suitable for its present needs.
The Company did not assume leases related to the Prodigy POPs in connection with
the Prodigy Transactions. The Company expects to enter additional leases as the
Phase II Expansion progresses.
 
LEGAL PROCEEDINGS
 
     The Company is not currently involved in any legal proceedings, nor are any
legal proceedings threatened by or against the Company.
 
                                   MANAGEMENT

(1) The potential realizable value through the expiration date of options has
    been determined on the basis of a per share price at the time the options
    were granted of $.625, compounded annually over ten years, net of the

    of appreciation and are not intended to forecast the possible future
    appreciation, if any, of the price or value of the Company's Common Stock.

    a price of $.625 per share upon his employment with the Company in 1998. The

(1) Options are "in-the-money" if the price of the Company's Common Stock
    exceeds the exercise price of the options. The value of unexercised options
    represents the difference between the exercise price of such options and the
    value of the Company's Common Stock on December 31, 1997, which is based on
    a valuation made by an independent firm and which was determined to be $1.10
    per share.
 
1997 INCENTIVE SHARE PLAN
 
     On June 16, 1997, the Company's 1997 Incentive Share Plan (the "Plan")
became effective. On April 1, 1998, the Board of Directors of the Company
approved and adopted an amendment and restatement of the Plan which was
subsequently approved and adopted by the stockholders of the Company on April
27, 1998. The purpose of the Plan is to provide employees, and certain
non-employee directors, and consultants with additional incentives by increasing
their ownership interests in the Company.
 
                                       78
<PAGE>   81
 
     Individual awards under the Plan may take the form of one or more of (i)
either incentive or non-qualified stock options, (ii) stock appreciation rights,
(iii) restricted stock and (iv) other awards, the value of which is based in
whole or in part upon the value of the Common Stock. Options under the Plan have
a term of ten years and are generally granted with an exercise price equivalent
to market value at the date of grant. Individual option grants vest over time,
based upon a schedule approved by the Board of Directors, which is generally
four years. All of the Company's Common Stock options vest automatically upon a
change in control of the Company, as defined.
 
     The Compensation Committee administers the Plan, determines the persons who
will receive awards and establishes the terms and conditions of those awards.
The President of the Company is also authorized, subject to certain limitations,
to grant awards to other employees. The maximum number of shares of Common Stock
that may be subject to outstanding awards is 20.0 million. As of July 15, 1998,
options for 3,404,500 shares had been granted. No options have been exercised
other than the option to purchase 1,000,000 shares granted to Mr. McLeod in May
1998, which was exercised in June 1998. See "-- Certain Relationships and
Related Transactions -- Financings." Shares of Common Stock which are
attributable to awards which have expired, terminated or been canceled or
forfeited are available for issuance or use in connection with future awards.
 
     Awards under the Plan may be made until January 1, 2007. The Plan may be
amended by the Board of Directors without the consent of the stockholders of the
Company.
 
DIRECTOR COMPENSATION
 
     The directors of the Company who are not also employees of the Company are
entitled to receive an annual fee of $10,000 and a fee of $500 for attending
each committee meeting not held on the same date as a regular meeting of
Directors (Mr. Wilkens and Mr. Salameh have waived all such cash compensation
for 1998), plus reimbursement for reasonable expenses incurred in conjunction
with attending meetings. Directors are also eligible for grants of awards under
the Plan. On May 28, 1998, each of the three outside directors was granted
options to purchase 80,000 shares of the Common Stock at $1.10 per share, with
options to purchase 20,000 of such shares vesting on each of the first four
anniversaries of the date of grant.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     In 1997, the compensation of the Company's executive officers was
determined by the Board of Directors. In 1998, the Board of Directors of the
Company appointed a compensation committee consisting of Kwok L. Li, William R.
Wilson, Samer Salameh and Roy Wilkens, who will determine the compensation of
the Company's executive officers consistent with guidelines established by the
Board of Directors. Mr. Li and Mr. Wilson are executive officers of the Company.
 
CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     Employment Agreements. The Company has entered into employment agreements
with William R. Wilson (the "Wilson Agreement") and Patrick J. McGettigan, Jr.
(the "McGettigan Agreement"). The Wilson Agreement terminates on March 15, 2002,
and provides for the payment of an initial base salary at an annual rate of not
less than $150,000 and entitles him to participate in employee benefit plans
offered to senior executives. The McGettigan Agreement terminates on August 31,
1999, and provides for the payment of an initial base salary at an annual rate
of not less than $140,000 and entitles him to participate in employee benefit
plans offered to senior executives. The base salaries are subject to adjustment
by the Board of Directors or the Compensation Committee.
 
     The Wilson Agreement contains certain confidentiality provisions and
provides for termination (a) for cause (i.e., final conviction of a felony or
crime involving moral turpitude or willful or grossly negligent violation of the
terms regarding confidentiality), (b) upon death or disability or (c) without
cause. If Mr. Wilson is terminated upon death or disability or without cause,
the Company is required to pay the base salary for the remaining term of the
Wilson Agreement. The Company has also indemnified Mr. Wilson pursuant to the
Wilson Agreement for actions taken as an officer and director. The Wilson
Agreement further provides that Mr. Wilson may engage in other business
endeavors without violating any of provisions of the
                                       79
<PAGE>   82
 
agreement and allows Mr. Wilson to terminate all obligations under the agreement
with 30 days written notice.
 
     The McGettigan Agreement provides for termination for cause (i.e., willful
and material breach of the McGettigan Agreement, intentional nonperformance,
willful dishonesty, fraud or misconduct with respect to the business or
conviction of a felony). If Mr. McGettigan is terminated by the Company for any
reason other than cause, the Company is required to pay the base salary for the
remaining term of the McGettigan Agreement. In addition, Mr. McGettigan can
terminate all obligations under the McGettigan Agreement upon 60 days written
notice.
 
     Financings. In March 1997, the Company issued to its founders, Kwok L. Li

The transaction price included an option, exercisable through September 18,
1998, to subscribe for an additional 5.0 million shares for $3.1 million. The
option, if exercised, would result in Orient Star holding approximately 30.2% of
the Common Stock of the Company. The Company expects Orient Star to exercise the
option. Samer Salameh, the President of Prodigy, an affiliate of Carso, became a
member of the Board of Directors of the Company in April 1998.
 
     In June 1998, Clark McLeod, CEO of McLeodUSA, a regional telecommunications

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
     The following is a summary of the material terms of certain indebtedness of
the Company.
 
     In connection with the Company's agreement with Ericsson, Ericsson provided
a $5.0 million credit facility to the Company. See "Business Suppliers". Such
credit facility is evidenced by a Secured Promissory Note and Agreement dated
April 30, 1998, which provides for interest at the rate of 11% per annum on the
outstanding balance thereunder, payable monthly in arrears on the first business
day of each calendar month commencing on June 1, 1998. The Secured Promissory
Note and Agreement provided that all principal and accrued and unpaid interest
under such Secured Promissory Note and Agreement would become due and payable in
full upon the earlier of (i) the date the Company sells any of its equity
securities or debt instruments or securities (other than issuances of equities
securities to officers, directors, employees, or consultants in the ordinary
course of business) in an aggregate amount equal to or greater than the then
outstanding principal amount thereunder, and (ii) October 30, 1998. Thus, all
outstanding principal and accrued and unpaid interest under such Secured
Promissory Note and Agreement became due upon consummation of the Unit Offering.
Such Secured Promissory Note and Agreement was secured by a security interest in
the Company's Yurie ATM switches (with certain exceptions), Ericsson power
equipment, and concrete shelters. As of July 15, 1998, the outstanding principal
balance due under such Secured Promissory Note and Agreement was $1.5 million.
Such indebtedness was repaid with the proceeds of the Unit Offering.
 
     The Company is indebted to Linsang, a stockholder of the Company controlled
by the Company's Chairman of the Board and Chief Technical Officer, Kwok L. Li,
for an aggregate of $11.0 million in principal, plus accrued interest, as a
result of advances made by Linsang to the Company. See "Management Certain
Relationships and Related Transactions." Such indebtedness, initially
represented by demand notes bearing annual interest of 9.75% and maturing on the
earlier of written demand or December 1, 2002, was exchanged for 11,000 Units in
connection with the Unit Offering.
 
     As of March 31, 1998, the Company had outstanding total future commitments
relating to noncancelable capital and operating leases of $22.8 million and $2.6
million, respectively. Operating leases primarily relate to leases of the NOCs
and the Company's corporate offices. Capital leases primarily relate to Network
equipment and require payments on a monthly basis over periods ranging from 24
to 48 months, with implicit interest rates of 9.0% to 12.0%. As of March 31,
1998 the Company was required to make minimum capital and operating lease
payments of $6.8 million, $9.6 million, $7.2 million, $1.2 million, and $0.6
million in the last nine months of 1998, 1999, 2000, 2001, and 2002,
respectively.
 
                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
     The authorized capital stock of the Company presently consists of 150.0
million shares of Common Stock and 25.0 million shares of Preferred Stock, $.001
par value per share ("Preferred Stock"). At July 15, 1998, there were 77.8
million outstanding shares of Common Stock and no shares of Preferred Stock
outstanding.
 
     The following are summaries of the terms of the Common Stock and the
Preferred Stock. Such summaries do not purport to be complete and are subject in
all respects to the Certificate of Incorporation and By-laws of the Company.
 
COMMON STOCK
 
     The holders of Common Stock are entitled to receive dividends when and as
declared by the Board of Directors of the Company out of funds legally available
therefor. See "Risk -- Factors Dividend Policy."
 
     The holders of Common Stock are entitled to one vote for each share on all
matters voted upon by stockholders, including the election of directors. Shares
of Common Stock do not have cumulative voting rights, which means that the
holders of more than 50% of such shares voting for the election of directors can
elect 100% of the directors if they choose to do so and, in such event, the
holders of the remaining shares so
 
                                       82
<PAGE>   85
 
voting will not be able to elect any directors. See "Risk Factors -- Control by
Principal Stockholders and Management; Transactions with Related Parties."
Holders of Common Stock do not have any conversion, redemption or preemptive
rights. In the event of the dissolution, liquidation or winding up of the
Company, holders of Common Stock will be entitled to share ratably in any assets
remaining after the satisfaction in full of the prior rights of creditors,
including holders of the Company's indebtedness, and the liquidation preference
of any Preferred Stock then outstanding.
 
PREFERRED STOCK
 
     Under Delaware law and the Company's Certificate of Incorporation, the
Company's Board of Directors has authority to issue, without further action by
stockholders, one or more series of Preferred Stock, and to determine at the
time of issuance of each such series the rights and preferences thereof
(including dividend rate, liquidation priority, benefit of a sinking fund,
redemption and conversion and voting rights, if any). The issuance of Preferred
Stock, while providing flexibility in connection with possible acquisitions and
other corporate purposes, could, among other things, adversely affect the voting
power or other rights of the holders of Common Stock.
 
     Holders of the Preferred Stock would be entitled to receive dividends, as
specifically provided with respect to each series, prior to the payment or
declaration of any dividends for the Common Stock.
 
CERTAIN BY-LAW PROVISIONS
 
     The Company's By-laws provide additional notice requirements for
stockholder nominations of candidates for election to the Board of Directors and
proposals for other business that may be properly brought before a meeting of
stockholders.
 
                            DESCRIPTION OF THE NOTES
 
GENERAL
 
     The Original Notes were issued, and the Exchange Notes are issuable, under
the Indenture dated as of July 24, 1998, between the Company and Bank of
Montreal Trust Company, as trustee (the "Trustee"), a copy of which has been
filed as an exhibit to the Registration Statement. The form and terms of the
Exchange Notes will be identical in all material respects to the form and terms
of the Original Notes, except that the Exchange Notes will have been registered
under the Securities Act and, therefore, will not bear legends restricting
transfer thereof. The Exchange Notes and the Original Notes are deemed the same
class of notes under the Indenture and are both entitled to the benefits
thereof. Whenever particular sections or defined terms of the Indenture not
otherwise defined herein are referred to, such sections or defined terms are
incorporated herein by reference.
 
     The following summary of certain provisions of the Indenture, the Notes and
the Escrow and Disbursement Agreement does not purport to be complete and is
subject to, and is qualified in its entirety by reference to, all the provisions
of the Indenture, including the definitions of certain terms therein and those
terms made a part thereof by the Trust Indenture Act of 1939, as amended, and
the Escrow Agreement. Capitalized terms used herein and not otherwise defined
have the meanings set forth in the section "Certain Definitions."
 
     The Indenture provides for the issuance of up to $50.0 million aggregate
principal amount of additional Notes having identical terms and conditions to
the Notes offered hereby (the "Additional Notes"), subject to compliance with
the covenants contained in the Indenture. Any Additional Notes will be part of
the same issue as the Notes offered hereby and will vote on all matters with the
Notes offered hereby.
 
     Principal of, premium, if any, and interest on the Notes is payable, and
the Notes may be exchanged or transferred, at the office or agency of the
Company in the Borough of Manhattan, The City of New York (which initially shall
be the corporate trust office of the Trustee, at 88 Pine Street, 19th Floor, New
York,
 
                                       83
<PAGE>   86
 
New York 10005), except that, at the option of the Company, payment of interest
may be made by check mailed to the registered holders of the Notes at their
registered addresses.
 
     The Notes will be issued only in fully registered form, without coupons, in
denominations of $1,000 and any integral multiple of $1,000. No service charge
will be made for any registration of transfer or exchange of Notes, but the
Company may require payment of a sum sufficient to cover any transfer tax or
other similar governmental charge payable in connection therewith.
 
TERMS OF THE NOTES
 
     The Original Notes are and the Exchange Notes will be senior obligations of
the Company and will mature on July 15, 2008. Each Note will bear interest at a
rate per annum shown on the front cover of this Prospectus from July 24, 1998,
or from the most recent date to which interest has been paid or provided for,
payable semiannually to Holders of record at the close of business on the
January 1 or July 1 immediately preceding the interest payment date on January
15 and July 15 of each year, commencing January 15, 1999.
 
DISBURSEMENT OF FUNDS; ESCROW ACCOUNT
 
     The Company has deposited $56.6 million in Temporary Cash Investments, an
amount that, together with the interest received thereon, is sufficient to pay
when due the first four semi-annual interest payments on the Notes. Such amounts
will be deposited in an escrow account (the "Escrow Account") held by the Escrow
Agent for the benefit of the Trustee under the Indenture in accordance with the
Escrow and Disbursement Agreement. The Company will enter into the Escrow and
Disbursement Agreement, which will provide, among other things, that funds may
be disbursed from the Escrow Account only to pay interest on the Notes (or, if a
portion of the Notes has been retired by the Company, funds representing the
interest payment on the retired Notes may be paid to the Company). Pending such
disbursement, the Company will cause all funds contained in the Escrow Account
to be invested in Temporary Cash Investments. Interest earned on these Temporary
Cash Investments will be added to the Escrow Account.
 
     Under the Escrow and Disbursement Agreement, the Company will grant to the
Trustee, for the benefit of the holders, a first priority and exclusive security
interest in the Escrow Account (the "Escrow Collateral"). The Escrow and
Disbursement Agreement will provide that the Trustee may foreclose on the Escrow
Collateral upon acceleration of the maturity of the Notes. Under the terms of
the Indenture, the proceeds of the Escrow Collateral will be applied, first, to
amounts owing to the Escrow Agent in respect of fees and expenses of the Escrow
Agent, and second, to the obligations of the Company to the holders under the
Notes and the Indenture. The ability of holders to realize upon the Escrow
Collateral may be subject to certain bankruptcy law limitations in the event of
the bankruptcy of the Company.
 
     Upon payment in full of the first four scheduled semi-annual payments on
the Notes, if no Default or Event of Default has occurred and is continuing, the
Escrow Collateral, if any, then remaining will be released to the Company.
 
OPTIONAL REDEMPTION
 
     Except as set forth in the following paragraph, the Notes will not be
redeemable at the option of the Company prior to July 15, 2003. On or after such
date, the Notes will be redeemable at the option of the Company, in whole or in
part, on not less than 30 nor more than 60 days prior notice, at the following
redemption prices (expressed as percentages of principal amount), plus accrued
and unpaid interest and liquidated damages (if any) to the redemption date
(subject to the right of holders of record on the relevant
 
                                       84
<PAGE>   87
 
record date to receive interest due on the relevant interest payment date), if
redeemed during the 12-month period commencing on July 15 of the years set forth
below:

2006 and thereafter.........................................    100.000%
</TABLE>
 
In addition, at any time and from time to time prior to July 15, 2001, the
Company may redeem up to a maximum of 35% of the original aggregate principal
amount of the Notes (calculated giving effect to any issuance of Additional
Notes) with the Net Cash Proceeds of one or more Equity Offerings by the
Company, at a redemption price equal to 111.75% of the principal amount thereof,
plus accrued and unpaid interest and liquidated damages, if any, to date of
redemption (subject to the right of holders of record on the relevant record
date to receive interest due on the relevant interest payment date); provided,
however, that at least 65% of the original aggregate principal amount of the
Notes remains outstanding immediately after each such redemption (calculated
giving effect to any issuance of Additional Notes). Any such redemption shall be
made within 60 days of such Equity Offering upon not less than 30 nor more than
60 days notice mailed to each holder of Notes being redeemed and otherwise in
accordance with the procedures set forth in the Indenture.
 
SELECTION
 
     In the case of any partial redemption, selection of the Notes for
redemption will be made by the Trustee on a pro rata basis, by lot or by such
other method as the Trustee in its sole discretion shall deem to be fair and
appropriate, although no Note of $1,000 in original principal amount or less
will be redeemed in part. If any Note is to be redeemed in part only, the notice
of redemption relating to such Note shall state the portion of the principal
amount thereof to be redeemed. A new Note in principal amount equal to the
unredeemed portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Note.
 
RANKING
 
     The indebtedness evidenced by the Notes will be unsecured Senior
Indebtedness of the Company, will rank pari passu in right of payment with all
existing and future Senior Indebtedness of the Company and will be senior in
right of payment to all existing and future Subordinated Obligations of the
Company. The Notes will also be effectively subordinated to any Secured
Indebtedness of the Company and its subsidiaries to the extent of the value of
the assets securing such Indebtedness.
 
     At March 31, 1998, after giving pro forma effect to the Offering and the
application of the proceeds therefrom, the Company would have had $21.1 million
of Indebtedness outstanding (other than the Notes), all of which would have been
Senior Indebtedness and all of which would have been Secured Indebtedness. The
Company currently does not have any Subsidiaries.
 
     Although the Indenture contains limitations on the amount of additional
Indebtedness that the Company may incur, under certain circumstances the amount
of such Indebtedness could be substantial and, in any case, such Indebtedness
may be Senior Indebtedness. See "-- Certain Covenants Limitation on
Indebtedness".

CHANGE OF CONTROL
 
     Upon the occurrence of any of the following events (each a "Change of
Control"), each Holder will have the right to require the Company to repurchase
all or any part of such Holder's Notes at a purchase price in cash equal to 101%
of the principal amount thereof plus accrued and unpaid interest and liquidated
damages, if any, to the date of repurchase (subject to the right of Holders of
record on the relevant record date to receive interest due on the relevant
interest payment date); provided, however, that notwithstanding the occurrence
of a Change of Control, the Company shall not be obligated to repurchase the
Notes pursuant to this section in the event that it has exercised its right to
redeem all the Notes under the terms of the section titled "Optional
Redemption":
 
          (i) prior to the first public offering of common stock of the Company,
     the Permitted Holders cease to be the "beneficial owner" (as defined in
     Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of a
     majority in the aggregate of the total voting power of the Voting Stock of
     the Company, whether as a result of issuance of securities of the Company,
     any merger, consolidation, liquidation or dissolution of the Company, any
     direct or indirect transfer of securities by any Permitted Holder or
     otherwise (for purposes of this clause (i) and clause (ii) below, the
     Permitted Holders shall be deemed to beneficially own any Voting Stock of
     an entity (the "specified entity") held by any other entity (the "parent
     entity") so long as the Permitted Holders beneficially own (as so defined),
     directly or indirectly, in the aggregate a majority of the voting power of
     the Voting Stock of the parent entity);
 
          (ii) on the date of or after the first public offering of common stock
     of the Company referred in clause (i), (A) any "person" (as such term is
     used in Sections 13(d) and 14(d) of the Exchange Act), other than one or
     more Permitted Holders, is or becomes the beneficial owner (as defined in
     clause (i) above, except that for purposes of this clause (ii) such person
     shall be deemed to have "beneficial ownership" of all shares that any such
     person has the right to acquire, whether such right is exercisable
     immediately or only after the passage of time), directly or indirectly, of
     more than 35% of the total voting power of the Voting Stock of the Company
     and (B) the Permitted Holders "beneficially own" (as defined in clause (i)
     above), directly or indirectly, in the aggregate a lesser percentage of the
     total voting power of the Voting Stock of the Company than such other
     person and do not have the right or ability by voting power, contract or
     otherwise to elect or designate for election a majority of the Board of
     Directors (for the purposes of this clause (ii), such other person shall be
     deemed to beneficially own any Voting Stock of a specified entity held by a
     parent entity, if such other person is the beneficial owner (as defined in
     this clause (ii)), directly or indirectly, of more than 35% of the voting
     power of the Voting Stock of such parent entity and the Permitted Holders
     "beneficially own" (as defined in clause (i) above), directly or
     indirectly, in the aggregate a lesser percentage of the voting power of the
     Voting Stock of such parent entity and do not have the right or ability by
     voting power, contract or otherwise to elect or designate for election a
     majority of the board of directors of such parent entity);
 
          (iii) during any period of two consecutive years, individuals who at
     the beginning of such period constituted the Board of Directors (together
     with any new directors whose election by such Board of Directors or whose
     nomination for election by the stockholders of the Company was approved by
     a vote of 66 2/3% of the directors of the Company then still in office who
     were either directors at the beginning of such period or whose election or
     nomination for election was previously so approved) cease for any reason to
     constitute a majority of the Board of Directors of the Company then in
     office;
 
          (iv) the adoption of a plan relating to the liquidation or dissolution
     of the Company; or
 
          (v) the merger or consolidation of the Company with or into another
     Person or the merger of another Person with or into the Company, or the
     sale of all or substantially all the assets of the Company to another
     Person (other than a Person that is controlled by the Permitted Holders),
     and, in the case of any such merger or consolidation, the securities of the
     Company that are outstanding immediately prior to such transaction and
     which represent 100% of the aggregate voting power of the Voting Stock of
     the Company are changed into or exchanged for cash, securities or property,
     unless pursuant to such transaction such securities are changed into or
     exchanged for, in addition to any other consideration,
 
                                       86
<PAGE>   89
 
     securities of the surviving Person or transferee that represent immediately
     after such transaction, at least a majority of the aggregate voting power
     of the Voting Stock of the surviving Person or transferee.
 
     Within 30 days following any Change of Control, the Company shall mail a
notice to each Holder with a copy to the Trustee (the "Change of Control Offer")
stating: (1) that a Change of Control has occurred and that such Holder has the
right to require the Company to purchase such Holder's Notes at a purchase price
in cash equal to 101% of the principal amount thereof, plus accrued and unpaid
interest and liquidated damages, if any, to the date of repurchase (subject to
the right of Holders of record on the relevant record date to receive interest
on the relevant interest payment date); (2) the circumstances and relevant facts
and financial information regarding such Change of Control; (3) the repurchase
date (which shall be no earlier than 30 days nor later than 60 days from the
date such notice is mailed); and (4) the instructions determined by the Company,
consistent with this covenant, that a Holder must follow in order to have its
Notes purchased.
 
     The Company will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in the Indenture applicable to a Change of Control Offer made by the Company and
purchases all Notes validly tendered and not withdrawn under such Change of
Control Offer.
 
     The Company will comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act and any other securities laws or regulations
in connection with the repurchase of Notes pursuant to this covenant. To the
extent that the provisions of any securities laws or regulations conflict with
provisions of this covenant, the Company will comply with the applicable
securities laws and regulations and will not be deemed to have breached its
obligations under this paragraph by virtue thereof.
 
     The Change of Control purchase feature is a result of negotiations between
the Company and the Initial Purchaser. Management has no present intention to
engage in a transaction involving a Change of Control, although it is possible
that the Company would decide to do so in the future. Subject to the limitations
discussed below, the Company could, in the future, enter into certain
transactions, including acquisitions, refinancings or other recapitalizations,
that would not constitute a Change of Control under the Indenture, but that
could increase the amount of indebtedness outstanding at such time or otherwise
affect the Company's capital structure or credit ratings. Restrictions on the
ability of the Company to incur additional Indebtedness are contained in the
covenants described under "Certain Covenants -- Limitation on Indebtedness",
"Certain Covenants -- Limitation on Liens" and "Certain Covenants -- Limitation
on Sale/Leaseback Transactions". Such restrictions can only be waived with the
consent of the holders of a majority in principal amount of the Notes then
outstanding. Except for the limitations contained in such covenants, however,
the Indenture will not contain any covenants or provisions that may afford
holders of the Notes protection in the event of a highly leveraged transaction.
 
     Future Senior Indebtedness of the Company may contain prohibitions of
certain events which would constitute a Change of Control or require such Senior
Indebtedness to be repurchased upon a Change of Control. Moreover, the exercise
by the Holders of their right to require the Company to repurchase the Notes
could cause a default under such Senior Indebtedness, even if the Change of
Control itself does not, due to the financial effect of such repurchase on the
Company. Finally, the Company's ability to pay cash to the Holders upon a
repurchase may be limited by the Company's then existing financial resources.
There can be no assurance that sufficient funds will be available when necessary
to make any required repurchases. The provisions under the Indenture relative to
the Company's obligation to make an offer to repurchase the Notes as a result of
a Change of Control may be waived or modified with the written consent of the
holders of a majority in principal amount of the Notes.
 
CERTAIN COVENANTS
 
     The Indenture contains covenants including, among others, the following:
 
     Limitation on Indebtedness. (a) The Company will not, and will not permit
any Restricted Subsidiary to, Incur, directly or indirectly, any Indebtedness;
provided, however, that the Company may Incur Indebtedness if on the date of
such Incurrence and after giving effect thereto the Debt to Annualized
                                       87
<PAGE>   90
 
Operating Cash Flow Ratio would be less than or equal to 6.0:1.0 if such
Indebtedness is Incurred prior to July 15, 2001 and less than or equal to
5.5:1.0 if such Indebtedness is Incurred on or after such date.
 
     (b) Notwithstanding the foregoing paragraph (a), the Company and its
Restricted Subsidiaries may Incur the following Indebtedness:
 
          (i) Bank Indebtedness in an aggregate principal amount not to exceed
     $75.0 million less the aggregate amount of all repayments of principal
     applied to permanently reduce any such Indebtedness;
 
          (ii) Indebtedness of the Company owed to and held by any Wholly Owned
     Subsidiary or Indebtedness of a Restricted Subsidiary owed to and held by
     the Company or any Wholly Owned Subsidiary; provided, however, that (i) any
     subsequent issuance or transfer of any Capital Stock or any other event
     that results in any such Wholly Owned Subsidiary ceasing to be a Wholly
     Owned Subsidiary or any subsequent transfer of any such Indebtedness
     (except to the Company or a Wholly Owned Subsidiary) shall be deemed, in
     each case, to constitute the Incurrence of such Indebtedness by the issuer
     thereof and (ii) if the Company is the obligor on such Indebtedness, such
     Indebtedness is expressly subordinated to the prior payment in full in cash
     of all obligations with respect to the Notes;
 
          (iii) Indebtedness (A) represented by the Notes (not including any
     Additional Notes), (B) outstanding on the Closing Date (other than the
     Indebtedness described in clauses (i) and (ii) above), (C) consisting of
     Refinancing Indebtedness Incurred in respect of any Indebtedness described
     in this clause (iii) (including Indebtedness Refinancing) or the foregoing
     paragraph (a), (D) consisting of Guarantees of any Indebtedness permitted
     under clauses (i) and (ii) of this paragraph (b) and (E) consisting of any
     Guarantees of the Notes;
 
          (iv) (A) Indebtedness of a Restricted Subsidiary Incurred and
     outstanding on or prior to the date on which such Restricted Subsidiary was
     acquired by the Company (other than Indebtedness Incurred as consideration
     in, or to provide all or any portion of the funds or credit support
     utilized to consummate, the transaction or series of related transactions
     pursuant to which such Restricted Subsidiary became a Subsidiary of or was
     otherwise acquired by the Company); provided, however, that on the date
     that such Restricted Subsidiary is acquired by the Company, the Company
     would have been able to Incur $1.00 of additional Indebtedness pursuant to
     the foregoing paragraph (a) after giving effect to the Incurrence of such
     Indebtedness pursuant to this clause (iv) and (B) Refinancing Indebtedness
     Incurred by a Restricted Subsidiary in respect of Indebtedness Incurred by
     such Restricted Subsidiary pursuant to this clause (iv);
 
          (v) Indebtedness (A) in respect of performance bonds, bankers'
     acceptances, letters of credit and surety or appeal bonds provided by the
     Company and the Restricted Subsidiaries in the ordinary course of their
     business, and (B) under Hedging Obligations entered into for bona fide
     hedging purposes of the Company in the ordinary course of business;
     provided, however, that such Hedging Obligations do not increase the
     Indebtedness of the Company outstanding at any time other than as a result
     of fluctuations in interest rates or currency exchange rates or by reason
     of fees, indemnities and compensation payable thereunder;
 
          (vi) Purchase Money Indebtedness, provided that the amount of such
     Purchase Money Indebtedness does not exceed the lesser of 80% of (a) the
     Fair Market Value of or (b) the cost of the construction, installation,
     acquisition, lease, development or improvement of, the applicable
     Telecommunications Assets;
 
          (vii) Contribution Indebtedness; or
 
          (viii) Indebtedness (other than Indebtedness permitted to be Incurred
     pursuant to the foregoing paragraph (a) or any other clause of this
     paragraph (b)) in an aggregate principal amount on the date of Incurrence
     that, when added to all other Indebtedness Incurred pursuant to this clause
     (viii) and then outstanding, shall not exceed $40.0 million.
 
     (c) Notwithstanding the foregoing, the Company may not Incur any
Indebtedness pursuant to paragraph (b) above if the proceeds thereof are used,
directly or indirectly, to repay, prepay, redeem, defease,
                                       88
<PAGE>   91
 
retire, refund or refinance any Subordinated Obligations unless such
Indebtedness will be subordinated to the Notes to at least the same extent as
such Subordinated Obligations.
 
     (d) Notwithstanding any other provision of this covenant, the maximum
amount of Indebtedness that the Company or any Restricted Subsidiary may Incur
pursuant to this covenant shall not be deemed to be exceeded solely as a result
of fluctuations in the exchange rates of currencies. For purposes of determining
the outstanding principal amount of any particular Indebtedness Incurred
pursuant to this covenant, (i) Indebtedness permitted by this covenant need not
be permitted solely by reference to one provision permitting such Indebtedness
but may be permitted in part by one such provision and in part by one or more
other provisions of this covenant permitting such Indebtedness and (ii) in the
event that Indebtedness meets the criteria of more than one of the types of
Indebtedness described in this covenant, the Company, in its sole discretion,
shall classify such Indebtedness and only be required to include the amount of
such Indebtedness in one of such clauses. Once so classified, such Indebtedness
shall retain such classification until repaid.
 
     Limitation on Restricted Payments. (a) The Company will not, and will not
permit any Restricted Subsidiary, directly or indirectly, to (i) declare or pay
any dividend or make any distribution on or in respect of its Capital Stock
(including any payment in connection with any merger or consolidation involving
the Company) or similar payment to the direct or indirect holders of its Capital
Stock except dividends or distributions payable solely in its Capital Stock
(other than Disqualified Stock) and except dividends or distributions payable to
the Company or another Restricted Subsidiary (and, if such Restricted Subsidiary
has stockholders other than the Company or other Restricted Subsidiaries, to its
other stockholders on a pro rata basis), (ii) purchase, redeem, retire or
otherwise acquire for value any Capital Stock of the Company or any Restricted
Subsidiary held by Persons other than the Company or another Restricted
Subsidiary, (iii) purchase, repurchase, redeem, defease or otherwise acquire or
retire for value, prior to scheduled maturity, scheduled repayment or scheduled
sinking fund payment any Subordinated Obligations (other than the purchase,
repurchase or other acquisition of Subordinated Obligations purchased in
anticipation of satisfying a sinking fund obligation, principal installment or
final maturity, in each case due within one year of the date of acquisition) or
(iv) make any Investment (other than a Permitted Investment) in any Person (any
such dividend, distribution, purchase, redemption, repurchase, defeasance, other
acquisition, retirement or Investment being herein referred to as a "Restricted
Payment") if at the time the Company or such Restricted Subsidiary makes such
Restricted Payment: (1) a Default will have occurred and be continuing (or would
result therefrom); (2) the Company could not Incur at least $1.00 of additional
Indebtedness under paragraph (a) of the covenant described under "-- Limitation
on Indebtedness"; or (3) the aggregate amount of such Restricted Payment and all
other Restricted Payments (the amount so expended, if other than in cash, to be
determined in good faith by the Board of Directors, whose determination will be
conclusive and evidenced by a resolution of the Board of Directors) declared or
made subsequent to the Closing Date would exceed the sum of: (A)(i) 100% of
Consolidated Operating Cash Flow accrued during the period (treated as one
accounting period) from the beginning of the fiscal quarter immediately
following the fiscal quarter during which the Closing Date occurs to the end of
the most recent fiscal quarter ending at least 45 days prior to the date of such
Restricted Payment (or, in case such Consolidated Operating Cash Flow during
such period is a deficit, minus 100% of such deficit), minus (ii) 150% of
Consolidated Interest Expense accrued during the period (treated as one
accounting period) from the beginning of the fiscal quarter immediately
following the fiscal quarter during which the Closing Date occurs to the end of
the most recent fiscal quarter ending at least 45 days prior to the date of such
Restricted Payment; plus, (B) the aggregate Net Cash Proceeds received by the
Company from the issue or sale of its Capital Stock (other than Disqualified
Stock) subsequent to the Closing Date (other than an issuance or sale to (x) a
Subsidiary of the Company or (y) an employee stock ownership plan or other trust
established by the Company or any of its Subsidiaries); plus, (C) the amount by
which Indebtedness of the Company or its Restricted Subsidiaries is reduced on
the Company's balance sheet upon the conversion or exchange (other than by a
Subsidiary of the Company) subsequent to the Closing Date of any Indebtedness of
the Company or its Restricted Subsidiaries issued after the Closing Date which
is convertible or exchangeable for Capital Stock (other than Disqualified Stock)
of the Company (less the amount of any cash or the fair market value of other
property distributed by the Company or any Restricted Subsidiary upon such
conversion or exchange); plus, (D) the amount equal to the net reduction in
Investments in Unrestricted Subsidiaries resulting from (i) payments of
dividends, repayments of the
                                       89
<PAGE>   92
 
principal of loans or advances or other transfers of assets to the Company or
any Restricted Subsidiary from Unrestricted Subsidiaries or (ii) the
redesignation of Unrestricted Subsidiaries as Restricted Subsidiaries (valued in
each case as provided in the definition of "Investment") not to exceed, in the
case of any Unrestricted Subsidiary, the amount of Investments previously made
by the Company or any Restricted Subsidiary in such Unrestricted Subsidiary,
which amount was included in the calculation of the amount of Restricted
Payments; and less, (E) the aggregate principal amount of any outstanding
Contribution Indebtedness or, if less, the Cash Contribution Amount.
 
     (b) The provisions of the foregoing paragraph (a) will not prohibit: (i)
any purchase, repurchase, retirement or other acquisition or retirement for
value of Capital Stock of the Company made by exchange for, or out of the
proceeds of the substantially concurrent sale of, Capital Stock of the Company
(other than Disqualified Stock and other than Capital Stock issued or sold to a
Subsidiary of the Company or an employee stock ownership plan or other trust
established by the Company or any of its Subsidiaries); provided, however, that
such purchase, repurchase, retirement or other acquisition or retirement for
value will be excluded in the calculation of the amount of Restricted Payments;
(ii) any purchase, repurchase, redemption, defeasance or other acquisition or
retirement for value of Subordinated Obligations of the Company made by exchange
for, or out of the proceeds of the substantially concurrent sale of,
Indebtedness of the Company that is permitted to be Incurred pursuant to
paragraph (b) of the covenant described under "-- Limitation on Indebtedness" or
Capital Stock of the Company (other than Disqualified Stock and other than
Capital Stock issued or sold to a Subsidiary of the Company or an employee stock
ownership plan or other trust established by the Company or any of its
Subsidiaries); provided, however, that such purchase, repurchase, redemption,
defeasance or other acquisition or retirement for value will be excluded in the
calculation of the amount of Restricted Payments; (iii) any purchase or
redemption of Subordinated Obligations from Net Available Cash to the extent
permitted by the covenant described under "-- Limitation on Sales of Assets and
Subsidiary Stock"; provided, however, that such purchase or redemption will be
included in the calculation of the amount of Restricted Payments; (iv) dividends
paid within 60 days after the date of declaration thereof if at such date of
declaration such dividend would have complied with this covenant; provided,
however, that such dividend will be included in the calculation of the amount of
Restricted Payments; or (v) the repurchase or other acquisition of shares of, or
options to purchase shares of, common stock of the Company or any of its
Subsidiaries from employees, former employees, directors or former directors of
the Company or any of its Subsidiaries (or permitted transferees of such
employees, former employees, directors or former directors), pursuant to the
terms of agreements (including employment agreements) or plans (or amendments
thereto) approved by the Board of Directors under which such individuals
purchase or sell or are granted the option to purchase or sell, shares of such
common stock; provided, however, that the aggregate amount of such repurchases
shall not exceed $1.0 million in any calendar year and $3.0 million in the
aggregate; provided further, that such repurchases and other acquisitions shall
be included in the calculation of the amount of Restricted Payments.
 
     Limitation on Restrictions on Distributions from Restricted
Subsidiaries. The Company will not, and will not permit any Restricted
Subsidiary to, create or otherwise cause or permit to exist or become effective
any consensual encumbrance or restriction on the ability of any Restricted
Subsidiary to (i) pay dividends or make any other distributions on its Capital
Stock or pay any Indebtedness or other obligations owed to the Company, (ii)
make any loans or advances to the Company or (iii) transfer any of its property
or assets to the Company, except: (1) any encumbrance or restriction pursuant to
(A) an agreement in effect at or entered into on the Closing Date or (B) an
agreement entered into in connection with the Incurrence of Indebtedness
permitted under clause (b)(i) or (b)(vi) of the covenant described under
"-- Limitation on Indebtedness", provided that the chief financial officer of
the Company has determined in good faith that any restriction incurred pursuant
to this clause (B) is customary for similar Incurrences of Indebtedness; (2) any
encumbrance or restriction with respect to a Restricted Subsidiary pursuant to
an agreement relating to any Indebtedness Incurred by such Restricted Subsidiary
prior to the date on which such Restricted Subsidiary was acquired by the
Company (other than Indebtedness Incurred as consideration in, in contemplation
of, or to provide all or any portion of the funds or credit support utilized to
consummate the transaction or series of related transactions pursuant to which
such Restricted Subsidiary became a Restricted Subsidiary or was otherwise
acquired by the Company) and outstanding on such date; (3) any encumbrance or
restriction
                                       90
<PAGE>   93
 
pursuant to an agreement effecting a Refinancing of Indebtedness Incurred
pursuant to an agreement referred to in clause (1) or (2) of this covenant or
this clause (3) or contained in any amendment to an agreement referred to in
clause (1) or (2) of this covenant or this clause (3); provided, however, that
the encumbrances and restrictions contained in any such refinancing agreement or
amendment are no less favorable to the Noteholders than the encumbrances and
restrictions contained in such predecessor agreements; (4) in the case of clause
(iii), any encumbrance or restriction (A) that restricts in a customary manner
the subletting, assignment or transfer of any property or asset that is subject
to a lease, license or similar contract, or (B) contained in security agreements
securing Indebtedness of a Restricted Subsidiary to the extent such encumbrance
or restriction restricts the transfer of the property subject to such security
agreements; and (5) with respect to a Restricted Subsidiary, any restriction
imposed pursuant to an agreement entered into for the sale or disposition of all
or substantially all the Capital Stock or assets of such Restricted Subsidiary
pending the closing of such sale or disposition.
 
     Limitation on Sales of Assets and Subsidiary Stock. (a) The Company will
not, and will not permit any Restricted Subsidiary to, make any Asset
Disposition unless (i) the Company or such Restricted Subsidiary receives
consideration (including by way of relief from, or by any other Person assuming
sole responsibility for, any liabilities, contingent or otherwise) at the time
of such Asset Disposition at least equal to the Fair Market Value of the shares
and assets subject to such Asset Disposition, (ii) at least 75% of the
consideration thereof received by the Company or such Restricted Subsidiary is
in the form of cash or cash equivalents and (iii) an amount equal to 100% of the
Net Available Cash from such Asset Disposition is applied by the Company (or
such Restricted Subsidiary, as the case may be) (A) first, to the extent the
Company elects (or is required by the terms of any Bank Indebtedness) to (x)
reinvest in Telecommunications Assets (including by means of an Investment in
Telecommunications Assets by a Restricted Subsidiary with Net Available Cash
received by the Company or another Restricted Subsidiary) or (y) prepay, repay,
redeem or purchase Bank Indebtedness of the Company Incurred pursuant to clause
(b)(i) of the covenant described under "-- Limitation on Indebtedness", in each
case within 180 days after the later of the date of such Asset Disposition or
the receipt of such Net Available Cash; (B) second, to the extent of the balance
of such Net Available Cash after application in accordance with clause (A), to
make an Offer (as defined below) to purchase Notes pursuant to and subject to
the conditions set forth in section (b) of this covenant within 365 days after
the later of such Asset Disposition or the receipt of such Net Available Cash;
provided, however, that if the Company elects (or is required by the terms of
any other Senior Indebtedness), such Offer may be made ratably to purchase the
Notes and other Senior Indebtedness of the Company, and (C) third, to fund (to
the extent consistent with any other applicable provision in the Indenture) any
corporate purpose. Notwithstanding the foregoing provisions of this covenant,
the Company and the Restricted Subsidiaries will not be required to apply any
Net Available Cash in accordance with this covenant except to the extent that
the aggregate Net Available Cash from all Asset Dispositions that is not applied
in accordance with this covenant exceeds $5.0 million.
 
     For the purposes of this covenant, the following are deemed to be cash: (x)
the assumption of Indebtedness of the Company (other than Disqualified Stock of
the Company) or any Restricted Subsidiary and the release of the Company or such
Restricted Subsidiary from all liability on such Indebtedness in connection with
such Asset Disposition and (y) securities received by the Company or any
Restricted Subsidiary from the transferee that are converted by the Company or
such Restricted Subsidiary into cash within 60 days of such receipt.
 
     (b) In the event of an Asset Disposition that requires the purchase of
Notes (and other Senior Indebtedness) pursuant to clause (a)(iii)(B) of this
covenant, the Company will be required to purchase Notes (and other Senior
Indebtedness) tendered pursuant to an offer by the Company for the Notes (and
other Senior Indebtedness) (the "Offer") at a purchase price of 100% of their
principal amount plus accrued and unpaid interest and liquidated damages, if
any, to the date of purchase in accordance with the procedures (including
prorating in the event of oversubscription), set forth in the Indenture. If the
aggregate purchase price of Notes (and other Senior Indebtedness) tendered
pursuant to the Offer is less than the Net Available Cash allotted to the
purchase of the Notes (and other Senior Indebtedness), the Company may apply the
remaining Net Available Cash in accordance with clause (a)(iii)(C) of this
covenant. The Company will not be required to make an Offer for Notes (and other
Senior Indebtedness) pursuant to this covenant if the Net
 
                                       91
<PAGE>   94
 
Available Cash available therefor (after application of the proceeds as provided
in clause (a)(iii)(A)) is less than $5.0 million for any particular Asset
Disposition (which lesser amount will be carried forward for purposes of
determining whether an Offer is required with respect to the Net Available Cash
from any subsequent Asset Disposition).
 
     (c) The Company will comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Notes pursuant to this
covenant. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this covenant, the Company will comply
with the applicable securities laws and regulations and will not be deemed to
have breached its obligations under this covenant by virtue thereof.
 
     Limitation on Transactions with Affiliates. (a) The Company will not, and
will not permit any Restricted Subsidiary to, directly or indirectly, enter into
or conduct any transaction (including the purchase, sale, lease or exchange of
any property or the rendering of any service) with any Affiliate of the Company
(an "Affiliate Transaction") unless such transaction is on terms (i) that are no
less favorable to the Company or such Restricted Subsidiary, as the case may be,
than those that could be obtained at the time of such transaction in
arm's-length dealings with a Person who is not such an Affiliate, (ii) that, in
the event such Affiliate Transaction involves an aggregate amount in excess of
$1.0 million, (1) are set forth in writing and (2) have been approved by a
majority of the members of the Board of Directors having no personal stake in
such Affiliate Transaction and (iii) that, in the event such Affiliate
Transaction involves an amount in excess of $20.0 million, have been determined
by a nationally recognized appraisal or investment banking firm to be fair, from
a financial standpoint, to the Company and its Restricted Subsidiaries.
 
     (b) The provisions of the foregoing paragraph (a) will not prohibit (i) any
Restricted Payment permitted to be paid pursuant to the covenant described under
"-- Limitation on Restricted Payments", (ii) any issuance of securities, or
other payments, awards or grants in cash, securities or otherwise pursuant to,
or the funding of, employment arrangements, stock options and stock ownership
plans approved by the Board of Directors, (iii) the grant of stock options or
similar rights to employees and directors of the Company pursuant to plans
approved by the Board of Directors, (iv) loans or advances to employees in the
ordinary course of business in accordance with past practices of the Company,
but in any event not to exceed $2.0 million in the aggregate outstanding at any
one time, (v) the payment of reasonable fees to directors of the Company and its
Subsidiaries who are not employees of the Company or its Subsidiaries, (vi) any
transaction between the Company and a Wholly Owned Subsidiary or between Wholly
Owned Subsidiaries or (vii) any transaction pursuant to, and on the terms set
forth in, the Prodigy Agreement.
 
     Limitation on the Sale or Issuance of Capital Stock of Restricted
Subsidiaries. The Company will not permit (a) any Restricted Subsidiary of the
Company to issue any Capital Stock except for (i) Capital Stock issued or sold
to, held by or transferred to the Company or a Wholly Owned Subsidiary, (ii)
Capital Stock issued by a Person prior to the time (A) such Person becomes a
Restricted Subsidiary of the Company, (B) such Person merges with or into a
Restricted Subsidiary of the Company or (C) a Restricted Subsidiary of the
Company merges with or into such Person; provided that such Capital Stock was
not issued or Incurred by such Person in anticipation of the type of transaction
contemplated by subclause (A), (B) or (C) (excluding for purposes of this
proviso, shares of Capital Stock issued in connection with customary accelerated
vesting provisions contained in option or similar plans or agreements which are
accelerated as a result of a change of control of such Person and which option
or similar plans or agreements were not adopted or implemented solely in
anticipation of or in connection with such transaction) or (b) any person (other
than the Company or a Wholly Owned Subsidiary) to acquire Capital Stock of any
Restricted Subsidiary of the Company from the Company or any Restricted
Subsidiary of the Company, except, in the case of each of clause (a) or (b), (1)
upon the acquisition of all the outstanding Capital Stock of such Restricted
Subsidiary in accordance with the covenant described under "-- Limitation on
Sales of Assets and Subsidiary Stock", (2) if, immediately after giving effect
to such issuance or sale, such Restricted Subsidiary would no longer constitute
a Restricted Subsidiary, and any Investment in such Person remaining after
giving effect to such issuance or sale would have been permitted to be made
pursuant to the covenant described under "-- Limitation on Restricted Payments"
if made on the date of such issuance or sale, and (3) if required, the issuance,
transfer, conveyance, sale or other disposition of directors' qualifying shares.
                                       92
<PAGE>   95
 
     Limitation on Liens. The Company will not, and will not permit any
Restricted Subsidiary to, directly or indirectly, Incur or permit to exist any
Lien of any nature whatsoever on any of its property or assets (including
Capital Stock of a Restricted Subsidiary), whether owned at the Closing Date or
thereafter acquired, other than Permitted Liens, without effectively providing
that the Notes shall be secured equally and ratably with (or prior to) the
obligations so secured for so long as such obligations are so secured; provided,
that if such obligations are expressly subordinated to the Notes or the
Subsidiary Guarantees the Lien securing such obligations will be subordinated
and junior to the Lien securing the Notes with the same relative priority as
such obligations have with respect to the Notes or the Subsidiary Guarantees.
 
     Commission Reports. Notwithstanding that the Company may not be subject to
the reporting requirements of Section 13 or 15(d) of the Exchange Act the
Company will file with the Commission and provide the Trustee and Noteholders
and prospective Noteholders (upon request) within 15 days after it files them
with the Commission, copies of its annual report and the information, documents
and other reports that are specified in Sections 13 and 15(d) of the Exchange
Act. In addition, following a public offering of the common stock of the
Company, the Company shall furnish to the Trustee and the Noteholders, promptly
upon their becoming available, copies of the annual report to stockholders and
any other information provided by the Company to its public stockholders
generally. The Company also will comply with the other provisions of Section
314(a) of the TIA.
 
     Future Subsidiary Guarantors. The Company will cause each Restricted
Subsidiary that Incurs Indebtedness to become a Subsidiary Guarantor, and
execute and deliver to the Trustee a supplemental indenture pursuant to which
such Restricted Subsidiary will Guarantee payment of the Notes. Each Subsidiary
Guarantee will be limited to an amount not to exceed the maximum amount that can
be Guaranteed by that Restricted Subsidiary without rendering the Subsidiary
Guarantee, as it relates to such Restricted Subsidiary, voidable under
applicable law relating to fraudulent conveyance or fraudulent transfer or
similar laws affecting the rights of creditors generally.
 
     Limitation on Lines of Business. The Company will not, and will not permit
any Restricted Subsidiary to, engage in any business other than a
Telecommunications Business.
 
     Limitation on Sale/Leaseback Transactions. The Company will not, and will
not permit any Restricted Subsidiary to, enter into any Sale/Leaseback
Transaction with respect to any property unless (a) the Company or such
Restricted Subsidiary would be entitled to (i) Incur Indebtedness in an amount
equal to the Attributable Debt with respect to such Sale/Leaseback Transaction
pursuant to the covenant described under "-- Limitation on Indebtedness" and
(ii) create a Lien on such property securing such Attributable Debt without
equally and ratably securing the Notes pursuant to the covenant described under
"-- Limitation on Liens", (b) the net proceeds received by the Company or such
Restricted Subsidiary in connection with such Sale/Leaseback Transaction are at
least equal to the fair market value (as determined in good faith by the Board
of Directors) of such property and (c) the transfer of such property is
permitted by, and the Company applies the proceeds of such transaction in
compliance with, the covenant described under "-- Limitation on Sale of Assets
and Subsidiary Stock".
 
MERGER AND CONSOLIDATION
 
     The Company will not consolidate with or merge with or into, or convey,
transfer or lease all or substantially all its assets to, any Person, unless:
(i) the resulting, surviving or transferee Person (the "Successor Company") will
be a corporation organized and existing under the laws of the United States of
America, any State thereof or the District of Columbia and the Successor Company
(if not the Company) will expressly assume, by a supplemental indenture and
other appropriate documents, executed and delivered to the Trustee, in form
satisfactory to the Trustee, all the obligations of the Company under the Notes,
the Indenture and the Escrow and Disbursement Agreement; (ii) immediately after
giving effect to such transaction (and treating any Indebtedness which becomes
an obligation of the Successor Company or any Restricted Subsidiary as a result
of such transaction as having been Incurred by the Successor Company or such
Restricted Subsidiary at the time of such transaction), no Default shall have
occurred and be continuing; (iii) immediately after giving effect to such
transaction, the Successor Company would be able to Incur an
 
                                       93
<PAGE>   96
 
additional $1.00 of Indebtedness under paragraph (a) of the covenant described
under "-- Certain Covenants -- Limitation on Indebtedness"; (iv) the Company
shall have delivered to the Trustee an Officers' Certificate and an Opinion of
Counsel, each stating that such consolidation, merger or transfer and such
supplemental indenture and other appropriate documents (if any) comply with the
Indenture and the Escrow and Disbursement Agreement; (v) the Company shall have
delivered to the Trustee an Opinion of Counsel to the effect that the Holders
will not recognize income, gain or loss for Federal income tax purposes as a
result of such transaction and will be subject to Federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if
such transaction had not occurred; and (vi) the Company shall have delivered to
the Trustee an Opinion of Counsel (subject to customary exceptions) to the
effect that any Subsidiary Guarantee shall remain in full force and effect after
such transaction.
 
     The Successor Company will succeed to, and be substituted for, and may
exercise every right and power of, the Company under the Indenture and the
Escrow and Disbursement Agreement, but the predecessor Company in the case of a
conveyance, transfer or lease of all or substantially all its assets will not be
released from the obligation to pay the principal of and interest on the Notes.
 
     The Company will not permit any Subsidiary Guarantor to consolidate with or
merge with or into, or convey, transfer or lease, all or substantially all of
its assets to any Person unless: (i) the resulting, surviving or transferee
Person will be a corporation organized and existing under the laws of the United
States of America, any State thereof or the District of Columbia, and such
Person (if not a Subsidiary Guarantor) will expressly assume, by a supplemental
indenture, executed and delivered to the Trustee, in form satisfactory to the
Trustee, all the obligations of such Subsidiary Guarantor under its Subsidiary
Guarantee; (ii) immediately after giving effect to such transaction (and
treating any Indebtedness which becomes an obligation of the resulting,
surviving or transferee Person as a result of such transaction as having been
incurred by such Person at the time of such transaction), no Default shall have
occurred and be continuing; and (iii) the Company shall have delivered to the
Trustee an Officers' Certificate and an Opinion of Counsel, each stating that
such consolidation, merger or transfer and such supplemental indenture (if any)
comply with the Indenture.
 
     Notwithstanding the foregoing, (a) any Restricted Subsidiary may
consolidate with, merge into or transfer all or part of its properties and
assets to the Company and (b) the Company may merge with an Affiliate
incorporated solely for the purpose of reincorporating the Company in another
jurisdiction to realize tax or other benefits.
 
DEFAULTS
 
     An Event of Default is defined in the Indenture as (i) a default in any
payment of interest on any Note when due and payable, continued for 30 days,
(ii) a default in the payment of principal of any Note when due and payable at
its Stated Maturity, upon required redemption or repurchase, upon declaration or
otherwise, (iii) the failure by the Company to comply with its obligations under
the covenant described under "-- Merger and Consolidation", (iv) the failure by
the Company to comply for 30 days after notice with any of its obligations under
the covenants described under "-- Change of Control" or "-- Certain Covenants"
(in each case, other than a failure to purchase Notes) or any of its agreements
contained in the Escrow and Disbursement Agreement, (v) the failure by the
Company to comply for 60 days after notice with its other agreements contained
in the Notes or the Indenture, (vi) the failure by the Company or any Subsidiary
to pay any Indebtedness within any applicable grace period after final maturity
or the acceleration of any such Indebtedness by the holders thereof because of a
default if the total amount of such Indebtedness unpaid or accelerated exceeds
$5.0 million or its foreign currency equivalent (the "cross acceleration
provision") and such failure continues for 10 days after receipt of the notice
specified in the Indenture, (vii) certain events of bankruptcy, insolvency or
reorganization of the Company or a Significant Subsidiary (the "bankruptcy
provisions"), (viii) the rendering of any judgment or decree for the payment of
money in excess of $5.0 million or its foreign currency equivalent against the
Company or a Significant Subsidiary if (A) an enforcement proceeding thereon is
commenced by any creditor or (B) such judgment or decree remains outstanding for
a period of 60 days following such judgment and is not discharged, waived or
stayed (the "judgment default provision"), (ix) any Subsidiary Guarantee ceases
to be in full force and effect (except as contemplated by the terms thereof) or
any Subsidiary Guarantor or Person acting by or on behalf of such
                                       94
<PAGE>   97
 
Subsidiary Guarantor denies or disaffirms such Subsidiary Guarantor's
obligations under the Indenture or any Subsidiary Guarantee and such Default
continues for 10 days after receipt of the notice specified in the Indenture, or
(x) the Company challenging the Lien on the Escrow Collateral under the Escrow
and Disbursement Agreement prior to the time that the Escrow Collateral is to be
released to the Company, the Escrow Collateral becoming subject to any lien
other than liens under the Escrow Agreement or the Escrow and Disbursement
Agreement becomes, or the Company asserts that the Escrow and Disbursement
Agreement is, invalid and unenforceable, other than in accordance with its
terms.
 
     The foregoing will constitute Events of Default whatever the reason for any
such Event of Default and whether it is voluntary or involuntary or is effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body.
 
     However, a default under clauses (iv), (v), (vi) or (ix) will not
constitute an Event of Default until the Trustee or the Holders of at least 25%
in principal amount of the outstanding Notes notify the Company of the default
and the Company does not cure such default within the time specified in clauses
(iv), (v), (vi) or (ix) hereof after receipt of such notice.
 
     If an Event of Default (other than an Event of Default relating to certain
events of bankruptcy, insolvency or reorganization of the Company) occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of
the outstanding Notes by notice to the Company may declare the principal of and
accrued but unpaid interest on all the Notes to be due and payable. Upon such a
declaration, such principal and interest will be due and payable immediately. If
an Event of Default relating to certain events of bankruptcy, insolvency or
reorganization of the Company occurs, the principal of and interest on all the
Notes will become immediately due and payable without any declaration or other
act on the part of the Trustee or any Holders. Under certain circumstances, the
Holders of a majority in principal amount of the outstanding Notes may rescind
any such acceleration with respect to the Notes and its consequences.
 
     Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default occurs and is continuing, the Trustee will
be under no obligation to exercise any of the rights or powers under the
Indenture at the request or direction of any of the Holders unless such Holders
have offered to the Trustee reasonable indemnity or security against any loss,
liability or expense. Except to enforce the right to receive payment of
principal, premium (if any) or interest when due, no Holder may pursue any
remedy with respect to the Indenture or the Notes unless (i) such Holder has
previously given the Trustee notice that an Event of Default is continuing, (ii)
Holders of at least 25% in principal amount of the outstanding Notes have
requested the Trustee in writing to pursue the remedy, (iii) such Holders have
offered the Trustee reasonable security or indemnity against any loss, liability
or expense, (iv) the Trustee has not complied with such request within 60 days
after the receipt of the request and the offer of security or indemnity and (v)
the Holders of a majority in principal amount of the outstanding Notes have not
given the Trustee a direction inconsistent with such request within such 60-day
period. Subject to certain restrictions, the Holders of a majority in principal
amount of the outstanding Notes are given the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or of exercising any trust or power conferred on the Trustee. The Trustee,
however, may refuse to follow any direction that conflicts with law or the
Indenture or that the Trustee determines is unduly prejudicial to the rights of
any other Holder or that would involve the Trustee in personal liability. Prior
to taking any action under the Indenture, the Trustee will be entitled to
indemnification satisfactory to it in its sole discretion against all losses and
expenses caused by taking or not taking such action.
 
     The Indenture provides that if a Default occurs and is continuing and is
known to the Trustee, the Trustee must mail to each Holder notice of the Default
within the earlier of 90 days after it occurs or 30 days after it is known to a
Trust Officer or written notice of it is received by the Trustee. Except in the
case of a Default in the payment of principal of, premium (if any) or interest
on any Note (including payments pursuant to the redemption provisions of such
Note), the Trustee may withhold notice if and so long as a committee of its
Trust Officers in good faith determines that withholding notice is in the
interests of the Noteholders. In addition, the Company is required to deliver to
the Trustee, within 120 days after the end of each fiscal year, a certificate
indicating whether the signers thereof know of any Default that occurred during
 
                                       95
<PAGE>   98
 
the previous year. The Company also is required to deliver to the Trustee,
within 30 days after the occurrence thereof, written notice of any event which
would constitute certain Events of Default, their status and what action the
Company is taking or proposes to take in respect thereof.
 
AMENDMENTS AND WAIVERS
 
     Subject to certain exceptions, the Indenture or the Notes may be amended
with the written consent of the Holders of a majority in principal amount of the
Notes then outstanding and any past default or compliance with any provisions
may be waived with the consent of the Holders of a majority in principal amount
of the Notes then outstanding. However, without the consent of each Holder of an
outstanding Note affected, no amendment may, among other things, (i) reduce the
amount of Notes whose Holders must consent to an amendment, (ii) reduce the rate
of or extend the time for payment of interest or any liquidated damages on any
Note, (iii) reduce the principal of or extend the Stated Maturity of any Note,
(iv) reduce the premium payable upon the redemption of any Note or change the
time at which any Note may be redeemed as described under "-- Optional
Redemption", (v) make any Note payable in money other than that stated in the
Note, (vi) impair the right of any Holder to receive payment of principal of and
interest or any liquidated damages on such Holder's Notes on or after the due
dates therefor or to institute suit for the enforcement of any payment on or
with respect to such Holder's Notes, (vii) make any change in the amendment
provisions which require each Holder's consent or in the waiver provisions,
(viii) modify the Subsidiary Guarantees in any manner adverse to the Holders, or
(ix) modify the provisions of the Escrow and Disbursement Agreement or the
Indenture relating to the Escrow Collateral in any manner adverse to the Holders
or release any of the Escrow Collateral from the Lien under the Escrow and
Disbursement Agreement or permit any other obligation to be secured by the
Escrow Collateral.
 
     Without the consent of any Holder, the Company and Trustee may amend the
Indenture to cure any ambiguity, omission, defect or inconsistency, to provide
for the assumption by a successor corporation of the obligations of the Company
under the Indenture, to provide for uncertificated Notes in addition to or in
place of certificated Notes (provided that the uncertificated Notes are issued
in registered form for purposes of Section 163(f) of the Code, or in a manner
such that the uncertificated Notes are described in Section 163(f)(2)(B) of the
Code), to add additional Guarantees with respect to the Notes, to secure the
Notes, to add to the covenants of the Company for the benefit of the Noteholders
or to surrender any right or power conferred upon the Company, to make any
change that does not adversely affect the rights of any Holder, subject to the
provisions of the Indenture, to provide for the issuance of the Exchange Notes,
or Additional Notes or to comply with any requirement of the Commission in
connection with the qualification of the Indenture under the TIA.
 
     The consent of the Noteholders is not necessary under the Indenture to
approve the particular form of any proposed amendment. It is sufficient if such
consent approves the substance of the proposed amendment.
 
     After an amendment under the Indenture becomes effective, the Company is
required to mail to the Noteholders a notice briefly describing such amendment.
However, the failure to give such notice to all Noteholders, or any defect
therein, will not impair or affect the validity of the amendment.
 
TRANSFER AND EXCHANGE
 
     A Noteholder may transfer or exchange Notes in accordance with the
Indenture. Upon any transfer or exchange, the registrar and the Trustee may
require a Noteholder, among other things, to furnish appropriate endorsements
and transfer documents and the Company may require a Noteholder to pay any taxes
required by law or permitted by the Indenture. The Company is not required to
transfer or exchange any Note selected for redemption or to transfer or exchange
any Note for a period of 15 days prior to a selection of Notes to be redeemed.
The Notes will be issued in registered form and the registered holder of a Note
will be treated as the owner of such Note for all purposes.
 
                                       96
<PAGE>   99
 
DEFEASANCE
 
     The Company at any time may terminate all its obligations under the Notes
and the Indenture ("legal defeasance"), except for certain obligations,
including those respecting the defeasance trust and obligations to register the
transfer or exchange of the Notes, to replace mutilated, destroyed, lost or
stolen Notes and to maintain a registrar and paying agent in respect of the
Notes. The Company at any time may terminate its obligations under the covenants
described under "-- Certain Covenants", the operation of the cross acceleration
provision, the bankruptcy provisions with respect to Significant Subsidiaries
and the judgment default provision described under "-- Defaults", the provisions
described under "Change of Control" and the limitations contained in clause
(iii) under the first paragraph of "-- Merger and Consolidation" ("covenant
defeasance").
 
     The Company may exercise its legal defeasance option notwithstanding its
prior exercise of its covenant defeasance option. If the Company exercises its
legal defeasance option, payment of the Notes may not be accelerated because of
an Event of Default with respect thereto. If the Company exercises its covenant
defeasance option, payment of the Notes may not be accelerated because of an
Event of Default specified in clause (iv), (vi), (vii) (with respect only to
Significant Subsidiaries) or (viii) under "-- Defaults" or because of the
failure of the Company to comply with clause (iii) under the first paragraph of
"-- Merger and Consolidation".
 
     In order to exercise either defeasance option, the Company must irrevocably
deposit in trust (the "defeasance trust") with the Trustee money or U.S.
Government Obligations for the payment of principal, premium (if any) and
interest on the Notes to redemption or maturity, as the case may be, and must
comply with certain other conditions, including delivery to the Trustee of an
Opinion of Counsel to the effect that holders of the Notes will not recognize
income, gain or loss for Federal income tax purposes as a result of such deposit
and defeasance and will be subject to Federal income tax on the same amounts and
in the same manner and at the same times as would have been the case if such
deposit and defeasance had not occurred (and, in the case of legal defeasance
only, such Opinion of Counsel must be based on a ruling of the Internal Revenue
Service or other change in applicable Federal income tax law).
 
CONCERNING THE TRUSTEE
 
     The Bank of Montreal Trust Company is to be the Trustee under the Indenture
and has been appointed by the Company as Registrar and Paying Agent with regard
to the Notes.
 
GOVERNING LAW
 
     The Indenture provides that it and the Notes will be governed by, and
construed in accordance with, the laws of the State of New York without giving
effect to applicable principles of conflicts of law to the extent that the
application of the law of another jurisdiction would be required thereby.
 
BOOK ENTRY, DELIVERY AND FORM
 
     Except as described in the next paragraph, the Exchange Notes (and the
related guarantees) initially will be represented by a single permanent global
certificate in definitive, fully registered form (the "Global Note"). The Global
Note will be deposited promptly after the Expiration Date with, or on behalf of,
The Depository Trust Company, New York, New York (the "Depositary") and
registered in the name of a nominee of the Depositary. Notes (i) originally
purchased by or transferred to "foreign purchasers" or (ii) held by qualified
institutional buyers or Accredited Investors (as defined in Regulation D under
the Securities Act) who are not "qualified institutional buyers" (as defined in
Rule 144A under the Securities Act) ("QIBs") who elect to take physical delivery
of their certificates instead of holding their interests through the Global Note
(and which are thus ineligible to trade through the Depositary) (collectively
referred to herein as the "Non-Global Purchasers") will be issued in registered
form (the "Certificated Security"). Upon the transfer to a QIB of any
Certificated Security initially issued to a Non-Global Purchaser, such
Certificated Security will, unless the transferee requests otherwise or the
Global Note has previously been
 
                                       97
<PAGE>   100
 
exchanged in whole for Certificated Securities, be exchanged for an interest in
the Global Note. For a description of the restrictions on the transfer of
Certificated Securities and any interest in the Global Note.
 
     The Global Note. The Company expects that pursuant to procedures
established by the Depositary (i) upon the issuance of the Global Note, the
Depositary or its custodian will credit, on its internal system, the principal
amount of Notes of the individual beneficial interests represented by such
Global Note to the respective accounts of persons who have accounts with such
depositary and (ii) ownership of beneficial interests in the Global Note will be
shown on, and the transfer of such ownership will be effected only through,
records maintained by the Depositary or its nominee (with respect to interests
of participants) and the records of participants (with respect to interests of
persons other than participants). Such accounts initially will be designated by
or on behalf of the Initial Purchaser and ownership of beneficial interests in
the Global Note will be limited to persons who have accounts with the Depositary
("participants") or persons who hold interests through participants. QIBs may
hold their interests in the Global Note directly through the Depositary if they
are participants in such system, or indirectly through organizations which are
participants in such system. So long as the Depositary, or its nominee, is the
registered owner or holder of the Notes, the Depositary or such nominee, as the
case may be, will be considered the sole owner or holder of the Notes
represented by such Global Note for all purposes under the Indenture. No
beneficial owner of an interest in the Global Note will be able to transfer that
interest except in accordance with the procedures of the Depositary, in addition
to those provided under the Indenture with respect to the Notes.
 
     The Depositary has advised the Company that it is (i) a limited purpose
trust company organized under the laws of the State of New York, (ii) a "banking
organization" within the meaning of the New York Banking Law, (iii) a member of
the Federal Reserve System, (iv) a "clearing corporation" within the meaning of
the Uniform Commercial Code, as amended, and (v) a "clearing agency" registered
pursuant to Section 17A of the Exchange Act. The Depositary was created to hold
securities for its participants (collectively, the "Participants") and
facilitates the clearance and settlement of securities transactions between
Participants through electronic book-entry changes to the accounts of its
Participants, thereby eliminating the need for physical transfer and delivery of
certificates. Participants in the Depositary include securities brokers and
dealers (including the Initial Purchaser), banks and trust companies, clearing
corporations and certain other organizations. Indirect access to the system of
the Depositary is also available to other entities such as banks, brokers,
dealers and trust companies (collectively, the "Indirect Participants") that
clear through or maintain a custodial relationship with a Participant, either
directly or indirectly. Investors who are not Participants may beneficially own
securities held by or on behalf of the Depositary only through Participants or
Indirect Participants.
 
     The laws of some jurisdictions may require that certain purchasers of
securities take physical delivery of such securities in definitive form.
Accordingly, the ability to transfer interests in the Securities represented by
a global security to such persons may be limited. In addition, because the
Depositary can act only on behalf of its Participants, who in turn act on behalf
of persons who hold interests through Participants, the ability of a person
having an interest in Securities represented by a global security to pledge or
transfer such interest to persons or entities that do not participate in the
system of the Depositary, or to otherwise take actions in respect of such
interest, may be affected by the lack of a physical definitive security in
respect of such interest.
 
     Payments with respect to the principal of, premium, if any, Liquidated
Damages, if any, and interest on, any Notes represented by the Global Note on
the applicable record date will be payable by the Trustee to or at the direction
of the Depositary or its nominee in its capacity as the registered holder of the
Global Note. Under the terms of the Indenture, the Company and the Trustee may
treat the persons in whose names the Notes, including the Global Note, are
registered as the owners thereof for the purpose of receiving payment thereon
and for any and all other purposes whatsoever. Accordingly, neither the Company
nor the Trustee has or will have any responsibility or liability for the payment
of such amounts to owners of beneficial interests in the Global Note (including
principal, premium, if any, Liquidated Damages, if any, and interest). Payments
by the Participants and the Indirect Participants to the owners of beneficial
interests in the Global Note will be governed by standing instructions and
customary industry practice and will be the responsibility of the Participants
or the Indirect Participants and the Depositary. Transfers between Participants
in the Depositary will be effected in accordance with the procedures of the
Depositary, and will be settled in same-day funds.
                                       98
<PAGE>   101
 
CERTIFICATED NOTES
 
     If (i) the Company notifies the Trustee in writing that the Depositary is
no longer willing or able to act as a depositary or the Depositary ceases to be
registered as a clearing agency under the Exchange Act and a successor
depositary is not appointed within 90 days of such notice or cessation, (ii) the
Company, at its option, notifies the Trustee in writing that it elects to cause
the issuance of Notes in definitive form or (iii) upon the occurrence of certain
other events, then, upon surrender by the Depositary of the Global Note,
Certificated Notes will be issued to each person that the Depositary identifies
as the beneficial owner of the Notes represented by the Global Note. Upon any
such issuance, the Trustee is required to register such Certificated Notes in
the name of such person or persons (or the nominee of any thereof) and cause the
same to be delivered thereto.
 
     Neither the Company nor the Trustee shall be liable for any delay by the
Depositary or any Participant or Indirect Participant in identifying the
beneficial owners of the related Notes and each such person may conclusively
rely on, and shall be protected in relying on, instructions from the Depositary
for all purposes.

                          DESCRIPTION OF THE WARRANTS
 
     The Warrants were issued pursuant to a Warrant Agreement dated July 24,
1998 (the "Warrant Agreement"), between the Company and Bank of Montreal Trust
Company, as warrant agent (the "Warrant Agent"). The following summary of
certain provisions of the Warrant Agreement does not purport to be complete and
is qualified in its entirety by reference to all of the provisions of the
Warrant Agreement, including the definitions therein of certain terms.
Capitalized terms in this "Description of the Warrants" not defined in this
Offering Memorandum have the meanings assigned to them in the Warrant Agreement.
 
GENERAL
 
     Each Warrant, when exercised, will entitle the holder thereof to purchase
10.125 shares of Common Stock from the Company at a price (the "Exercise Price")
of $0.01 per share. The Exercise Price and the number of shares of Common Stock
issuable upon exercise of a Warrant are both subject to adjustment in certain
cases. See "-- Adjustments" below. The Warrants initially entitle the holders
thereof to acquire, in the aggregate, 2,642,613 shares of Common Stock.
 
                                       109
<PAGE>   112
 
     The Warrants may be exercised at any time after the first anniversary of
the Issue Date; provided, however, that holders of Warrants will be able to
exercise their Warrants only if the Common Shelf Registration Statement (as
defined) relating to the Common Stock underlying the Warrants is effective or
the exercise of such Warrants is exempt from the registration requirements of
the Securities Act, and such securities are qualified for sale or exempt from
qualification under the applicable securities laws of the states or other
jurisdictions in which such holders reside. Unless earlier exercised, the
Warrants will expire on July 15, 2008. The Company will give notice of
expiration not less than 90 nor more than 120 days before the Expiration Date to
the registered holders of the then outstanding Warrants. If the Company fails to
give such notice, the Warrants will nevertheless expire and become void on the
Expiration Date. The Warrants will not trade separately from the Notes until the
Separation Date.
 
     At the Company's option, fractional shares of Common Stock may not be
issued upon exercise of the Warrants. If any fraction of a share of Common Stock
would, except for the foregoing provision, be issuable upon the exercise of any
such Warrant (or specified portion thereof), the Company will pay an amount in
cash equal to the Current Market Value per share of Common Stock, as determined
on the day immediately preceding the date the Warrant is presented for exercise,
multiplied by such fraction, computed to the nearest whole cent.
 
     Certificates for Warrants will be issued in fully registered form only. No
service charge will be made for registration of transfer or exchange upon
surrender of any Warrant Certificate at the office of the Warrant Agent
maintained for that purpose. The Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Warrant Certificates.
 
     In the event a bankruptcy, reorganization or similar proceeding is
commenced by or against the Company, a bankruptcy court may hold that
unexercised Warrants are executory contracts which may be subject to rejection
by the Company with approval of the bankruptcy court. As a result, holders of
the Warrants may, even if sufficient funds are available, not be entitled to
receive any consideration or may receive an amount less than they would be
entitled to if they had exercised their Warrants prior to the commencement of
any such bankruptcy, reorganization or similar proceeding.
 
CERTAIN TERMS
 
  Exercise
 
     In order to exercise all or any of the Warrants, the holder thereof is
required to surrender to the Warrant Agent the related Warrant Certificate and
pay in full the Exercise Price for each share of Common Stock or other
securities issuable upon exercise of such Warrants. The Exercise Price may be
paid (i) in cash or by certified or official bank check or by wire transfer to
an account designated by the Company for such purpose or (ii) without the
payment of cash, by reducing the number of shares of Common Stock that would be
obtainable upon the exercise of a Warrant and payment of the Exercise Price in
cash so as to yield a number of shares of Common Stock upon the exercise of such
Warrant equal to the product of (a) the number of shares of Common Stock for
which such Warrant is exercisable as of the date of exercise (if the Exercise
Price were being paid in cash) and (b) the Cashless Exercise Ratio (the
"Cashless Exercise"). The "Cashless Exercise Ratio" shall equal a fraction, the
numerator of which is the excess of the Current Market Value per share of Common
Stock on the Exercise Date over the Exercise Price per share as of the Exercise
Date and the denominator of which is the Current Market Value per share of the
Common Stock on the Exercise Date. Upon surrender of a Warrant Certificate
representing more than one Warrant in connection with the holder's option to
elect a Cashless Exercise, the number of shares of Common Stock deliverable upon
a Cashless Exercise shall be equal to the number of shares of Common Stock
issuable upon the exercise of Warrants that the holder specifies are to be
exercised pursuant to a Cashless Exercise multiplied by the Cashless Exercise
Ratio. All provisions of the Warrant Agreement shall be applicable with respect
to a surrender of a Warrant Certificate pursuant to a Cashless Exercise for less
than the full number of Warrants represented thereby.
 
                                       110
<PAGE>   113
 
  No Rights as Stockholders
 
     The holders of unexercised Warrants are not entitled, by virtue of being
such holders, to receive dividends, to vote, to consent, to exercise any
preemptive rights or to receive notice as stockholders of the Company in respect
of any stockholders' meeting for the election of directors of the Company or any
other purpose, or to exercise any other rights whatsoever as stockholders of the
Company.
 
  Mergers, Consolidations, etc.
 
     If the Company consolidates with, merges with or into, or sells all or
substantially all of its assets to, another Person, each Warrant thereafter will
entitle the holder thereof to receive upon exercise thereof, per share of Common
Stock for which such Warrant is exercisable, the number of shares of common
stock or other securities or property which the holder of a share of Common
Stock is entitled to receive upon completion of such consolidation, merger or
sale of assets. However, if (i) the Company consolidates with, merges with or
into, or sells all or substantially all of its assets to, another Person and, in
connection therewith, the consideration payable to the holders of Common Stock
in exchange for their shares is payable solely in cash or (ii) there is a
dissolution, liquidation or winding-up of the Company, then the holders of the
Warrants will be entitled to receive distributions on an equal basis with the
holders of Common Stock or other securities issuable upon exercise of the
Warrants, as if the Warrants had been exercised immediately prior to such event,
less the Exercise Price. Upon receipt of such payment, if any, the Warrants will
expire and the rights of the holders thereof will cease. In the case of any such
merger, consolidation or sale of assets, the surviving or acquiring person and,
in the event of any dissolution, liquidation or winding-up of the Company, the
Company, must deposit promptly with the Warrant Agent the funds, if any,
required to pay the holders of the Warrants. After such funds and the
surrendered Warrant Certificates are received, the Warrant Agent is required to
deliver a check in such amount as is appropriate (or, in the case of
consideration other than cash, such other consideration as is appropriate) to
such Persons as it may be directed in writing by the holders surrendering such
Warrants.
 
ADJUSTMENTS
 
     The number of shares of Common Stock issuable upon the exercise of the
Warrants and the Exercise Price will be subject to adjustment in certain events
including: (i) the payment by the Company of certain dividends (or other
distributions) on the Common Stock of the Company including dividends or
distributions payable in shares of Common Stock or other shares of the Company's
capital stock, (ii) subdivisions, combinations and certain reclassifications to
the Common Stock, (iii) the issuance to all holders of Common Stock of rights,
options or warrants entitling them to subscribe for shares of Common Stock, or
of securities convertible into or exchangeable or exercisable for shares of
Common Stock, for a consideration per share which is less than the Current
Market Value per share of the Common Stock, (iv) the issuance of shares of
Common Stock for a consideration per share which is less than the Current Market
Value per share of the Common Stock, and (v) the distribution to all holders of
the Common Stock of any of the Company's assets, debt securities or any rights
or warrants to purchase securities (excluding those rights and warrants referred
to in the foregoing clause (iii) and cash dividends and other cash distributions
from current or retained earnings other than any Extraordinary Cash Dividend).
No adjustment to the number of shares of Common Stock issuable upon the exercise
of the Warrants and the Exercise Price will be required in certain events
including: (i) the issuance of shares of Common Stock in bona fide public
offerings that are underwritten or in which a placement agent is retained by the
Company, (ii) the issuance of shares of Common Stock (including upon exercise of
options) pursuant to the terms of and in order to give effect to the 1997
Incentive Share Plan and (iii) the issuance of shares of Common Stock in
connection with acquisitions other than to affiliates of the Company.
 
     In the event of a distribution to holders of Common Stock which results in
an adjustment to the number of shares of Common Stock or other consideration for
which a Warrant may be exercised, the holders of the Warrants may, in certain
circumstances, be deemed to have received a distribution subject to United
States Federal income tax as a dividend. See "Certain Federal Income Tax
Considerations".
 
                                       111
<PAGE>   114
 
     No adjustment in the Exercise Price will be required unless such adjustment
would require an increase or decrease of at least one percent in the Exercise
Price; provided, however, that any adjustment which is not made as a result of
this paragraph will be carried forward and taken into account in any subsequent
adjustment.
 
AMENDMENT
 
     From time to time, the Company and the Warrant Agent, without the consent
of the holders of the Warrants, may amend or supplement the Warrant Agreement
for certain purposes, including curing defects or inconsistencies or making any
change that does not adversely affect the rights of any holder. Any amendment or
supplement to the Warrant Agreement that has an adverse effect on the interests
of the holders of the Warrants shall require the written consent of the holders
of a majority of the then outstanding Warrants. The consent of each holder of
the Warrants affected shall be required for any amendment pursuant to which the
Exercise Price would be increased or the number of shares of Common Stock
issuable upon exercise of Warrants would be decreased (other than pursuant to
adjustments provided in the Warrant Agreement).
 
REGISTRATION RIGHTS
 
     Registration of Warrants. The Company is required under the Warrant
Agreement to file a shelf registration statement under the Securities Act
covering the resale of the Warrants by the holders thereof (the "Warrant Shelf
Registration Statement") within 45 days after the Issue Date and to use its best
efforts to cause the Warrant Shelf Registration Statement to be declared
effective under the Securities Act within 105 days after the date of original
issuance of the Warrants and to remain effective until the earliest of (i) such
time as all of the Warrants have been sold thereunder, (ii) two years after its
effective date and (iii) such time as the Warrants can be sold without
restriction under the Securities Act.
 
     Each holder of Warrants that sells such Warrants pursuant to the Warrant
Shelf Registration Statement generally will be required to be named as a selling
securityholder in the related prospectus and to deliver a prospectus to the
purchaser, will be subject to certain of the civil liability provisions under
the Securities Act in connection with such sales and will be bound by certain
provisions of the Warrant Agreement which are applicable to such holder
(including certain indemnification obligations). In addition, each holder of
Warrants will be required to deliver information to be used in connection with
the Warrant Shelf Registration Statement in order to have its Warrants included
in the Warrant Shelf Registration Statement.
 
     Registration of Underlying Common Stock. The Company is required under the
Warrant Agreement to file a shelf registration statement under the Securities
Act covering the issuance of shares of Common Stock to the holders of the
Warrants upon exercise of the Warrants by the holders thereof (the "Common Shelf
Registration Statement") and to use its best efforts to cause the Common Shelf
Registration Statement to be declared effective on or before 365 days after the
Issue Date and to remain effective until the earlier of (i) such time as all
Warrants have been exercised and (ii) the Expiration Date.
 
     During any consecutive 365-day period, the Company shall be entitled to
suspend the availability of each of the Warrant Shelf Registration Statement and
the Common Shelf Registration Statement for up to two 45 consecutive-day periods
(except for the 45 consecutive-day period immediately prior to the Expiration
Date) if the Board of Directors of the Company determines in the exercise of its
reasonable judgment that there is a valid business purpose for such suspension
and provides notice that such determination was made to the holders of the
Warrants; provided, however, that in no event shall the Company be required to
disclose the business purpose for such suspension if the Company determines in
good faith that such business purpose must remain confidential. There can be no
assurance that the Company will be able to file, cause to be declared effective,
or keep a registration statement continuously effective until all of the
Warrants have been exercised or have expired.

     Act, (a) the value of the security, determined in good faith by the Board

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
GENERAL
 
     The following is a summary of material United States Federal income tax
consequences relevant in the opinion of Winstead Sechrest & Minick P.C., counsel
to the Company, to the Exchange Offer and the acquisition, ownership and
disposition of the Exchange Notes, but does not purport to be a complete
analysis of all potential tax effects. This summary is based upon the Internal
Revenue Code of 1986, as amended (the "Code"), existing and proposed regulations
thereunder (the "Regulations"), published rulings and court decisions, all as in
effect and existing on the date hereof and all of which are subject to change at
any time, which change may be retroactive. Such counsel has relied upon
representations by the Company and its officers with respect to factual matters
for purposes of this summary. This summary is not binding on the Internal
Revenue Service or on the courts, and no ruling will be requested from the
Internal Revenue Service on any issues described below. There can be no
assurance that the Internal Revenue Service will not take a different position
concerning the matters discussed below and that such positions of the Internal
Revenue Service would not be sustained.
 
     This summary applies only to U.S. Holders (as defined below) that are the
initial holders of the Original Notes and the Exchange Notes, who acquired the
Notes for cash and who hold the Notes as capital assets. It does not address the
tax consequences to taxpayers who are subject to special rules (such as
financial institutions, tax-exempt organizations, insurance companies, dealers
in securities or currencies and persons who hold Notes as a hedge or as a
position in a "straddle" for tax purposes). A "U.S. Holder" means a beneficial
owner of a Note who purchased the Notes pursuant to the offering of the Original
Notes that is for U.S. federal income tax purposes (i) a citizen or resident of
the United States; (ii) a corporation, partnership or other entity created or
organized in or under the laws of the United States or any political subdivision
thereof; (iii) an estate the income of which is subject to U.S. federal income
taxation regardless of its source; or (iv) a trust if (A) a court within the
United States is able to exercise primary supervision over the
                                       113
<PAGE>   116
 
administration of the trust and (B) one or more U.S. fiduciaries have the
authority to control all substantial decisions of the trust.
 
     THE FOLLOWING DISCUSSION IS FOR GENERAL INFORMATION ONLY. EACH HOLDER OF A
NOTE IS STRONGLY URGED TO CONSULT WITH ITS OWN TAX ADVISORS TO DETERMINE THE
IMPACT OF SUCH HOLDER'S TAX SITUATION ON THE ANTICIPATED TAX CONSEQUENCES,
INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN OR OTHER TAX LAWS, OF
THE ACQUISITION, OWNERSHIP AND DISPOSITION OF THE NOTES.
 
THE EXCHANGE
 
     The exchange of the Original Notes for the Exchange Notes pursuant to the
Exchange Offer should not be a taxable event to the holder and thus the holder
should not recognize any taxable gain or loss as a result of the exchange. A
holder's adjusted tax basis in the Exchange Notes will be the same as its
adjusted tax basis in the Original Notes exchanged therefor, and its holding
period for the Original Notes will be included in its holding period for the
Exchange Notes. To the extent that a holder acquired the Original Notes at a
market discount or with amortizable bond premium, such discount or premium would
generally carry over to the Exchange Notes received in exchange for the Original
Notes. Such holders should consult their tax advisers regarding the United
States federal income tax treatment of market discount or amortizable bond
premium.
 
TAXATION OF THE NOTES
 
     The stated interest payable on the Notes generally will be taxable to a
holder of Notes as ordinary income at the time that it is paid or accrued in
accordance with the holder's method of accounting for Federal income tax
purposes.
 
     The Notes were issued with de minimis original issue discount ("OID") for
Federal income tax purposes. A debt instrument generally is issued with de
minimis OID if the amount by which its stated redemption price at maturity
exceeds its issue price is less than the product of .0025 multiplied by the
product of the stated redemption price at maturity and the number of complete
years to maturity from the issue date. De minimis OID is recognized as capital
gain upon the redemption, sale or other taxable disposition of the debt
instrument.
 
     The issue price of the Notes is determined by allocating the "issue price"
of the Units between the Notes and the Warrants based on their relative fair
market values. The issue price of the Units was the first price at which a
substantial amount of the Units were sold for money. For purposes of determining
the issue price of the Notes, sales to bond houses, brokers or similar persons
or organizations acting in the capacity of underwriters, placement agents or
wholesalers are ignored. For purposes of determining whether OID is de minimis,
the issue price of the Notes is equal to the amount so allocated to the Notes.
The Company's allocation will be binding on a holder (but not on the Internal
Revenue Service) unless the holder discloses a different allocation on an
attachment to the holder's timely filed Federal income tax return for the
taxable year that includes the acquisition date of the Unit. The Company intends
to allocate 98.9% and 1.1% of the initial issue price of the Units to the Notes
and the Warrants, respectively.
 
     Sale, Retirement or Other Taxable Disposition. Gain or loss upon a sale or
other disposition of a Note will be measured by the difference between the
amount of cash and the fair market value of property received with respect to
such sale and the holder's adjusted tax basis in such Note. A holder's adjusted
tax basis in a Note generally will be equal to the portion of the cost of the
Unit allocated to the Note (i.e., in the case of an initial purchaser in the
Offering, the Note's issue price. Such gain or loss generally will be capital
gain or loss, and will be long-term capital gain or loss if the holder held the
Note for more than one year.
 
     Effect of Change of Control. Upon a Change of Control, each holder will
have the right to require the Company to repurchase all or any part of such
holder's Notes for a price equal to 101% of the principal amount thereof plus
accrued and unpaid interest and liquidated damages, if any, to the date of
payment. Under the Regulations, a provision such as the Change of Control
redemption requirement will not affect the
 
                                       114
<PAGE>   117
 
yield or maturity date of the Notes unless, based on all facts and circumstances
as of the date of issuance, it is more likely than not that a Change of Control
giving rise to the redemption will occur. The Company will not treat the Change
of Control redemption provision of the Notes as affecting the calculation of the
yield to maturity of any Note.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     The backup withholding and information reporting requirements may apply to
certain payments of principal and interest on a Note and to certain payments or
proceeds of the sale or retirement of a Note. The Company, its agent, a broker,
the Trustee or any paying agent, as the case may be, is required to withhold tax
from any payment that is subject to backup withholding at a rate of 31% of such
payment if the holder fails to furnish its taxpayer identification number
(social security number or employer identification number), to certify that such
holder is not subject to backup withholding rules. Certain holders (including,
among others, all corporations) are not subject to the backup withholding and
reporting requirements.
 
     Under current Treasury regulations, backup withholding and information
reporting do not apply to payments made by the Company or any agent thereof (in
its capacity as such) to a holder of a Note who has provided the required
certification under penalties of perjury that it is not a U.S. Holder or has
otherwise established an exemption (provided that neither the Company nor such
agent has actual knowledge that the holder is a U.S. Holder or that the
conditions of any other exemption are not in fact satisfied).
 
     Any amounts withheld under the backup withholding rules from a payment to a
holder may be claimed as a credit against such holder's United States federal
income tax liability.
 
                              PLAN OF DISTRIBUTION
 
     Each broker-dealer that receives Exchange Notes for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Notes. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of Exchange Notes received in
exchange for Original Notes where such Original Notes were acquired as a result
of market-making activities or other trading activities. The Company has agreed
that for a period of 180 days after the Expiration Date, it will make this
Prospectus, as amended or supplemented, available to any broker-dealer for use
in connection with any such resale.
 
     The Company will not receive any proceeds from any sales of the Exchange
Notes by broker-dealers. Exchange Notes received by broker-dealers for their own
account pursuant to the Exchange Offer may be sold from time to time in one or
more transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the Exchange Notes or a combination of such
methods of resale, at market prices prevailing at the time of resale, at prices
related to such prevailing market prices or negotiated prices. Any such resale
may be made directly to the purchaser or to or through brokers or dealers who
may receive compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any such Exchange Notes. Any
broker-dealer that resells the Exchange Notes that were received by it for its
own account pursuant to the Exchange Offer and any broker or dealer that
participates in a distribution of such Exchange Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit on any
such resale of Exchange Notes and any commissions or concessions received by any
such persons may be deemed to be underwriting compensation under the Securities
Act. The Letter of Transmittal states that by acknowledging that it will deliver
and by delivering a prospectus, a broker-dealer will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act.
 
     For a period of 180 days after the Expiration Date, the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requires such documents
in the Letter of Transmittal. The Company has agreed to pay all expenses
incident to the Exchange Offer, other than commissions or concessions of any
brokers or dealers, and will indemnify the holders of the Original Notes
(including any broker-dealers) against certain liabilities, including
liabilities under the Securities Act.

period from inception (March 5, 1997) to 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 audit. We conducted our audit
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

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 audit provides a
reasonable basis for the opinion expressed above.

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Splitrock Services, Inc. (the "Company") was formed as a Texas corporation
on March 5, 1997. The Company was formed to build a nationwide, facilities-based
telecommunications network with the goal of providing telecommunications
services. The Company has designed and is in the process of deploying a network
based on Asynchronous Transfer Mode (ATM) switching technology which it believes
will provide high quality communications services on a flexible multi-service
platform. This platform flexibility will allow the Company to expand its service
offerings to provide fully integrated data, video and voice services and to
incorporate future technological innovations into its Network architecture with
a lower incremental investment than that required by other, less flexible,
networks. On June 24, 1997, the Company entered into a four-year service
agreement to provide Internet dial access services to Prodigy (Note 2).
 
     During 1997, the Company launched the network construction program based on
ATM technology. This program was organized in two phases. As of December 31,
1997, the Company was in Phase I of the Network build which encompassed the
replacement of the network facilities previously owned by Prodigy (Note 2). The
Company anticipates the completion of Phase I in the first half of 1998.
 
     In addition to the development of a new telecommunications network, the
Company has been engaged in recruiting management and operational personnel and
structuring financing for the Company's operations. The development of the
network will require substantial capital expenditures. Management of the Company
believes that funding from affiliates of its stockholders or other sources will
be sufficient to fund the Company's operations for the next twelve months.
 
     The following is a summary of the Company's significant accounting
policies:
 
          Revenue Recognition. The Company recognizes revenue as services are
     provided under its agreement with its customer. Prodigy was the Company's
     only customer through December 31, 1997. Prodigy may terminate it's
     agreement with the Company without payment in the event of certain defaults
     by the Company, including documented failures (without cure) to meet
     certain network performance standards.
 
          Legacy Network Costs. The Legacy Network refers to certain assets
     which the Company acquired from Prodigy on July 1, 1997 related to
     Prodigy's existing network infrastructure in order to provide services to
     Prodigy while the Splitrock Network is being fully deployed (Note 2).
     Legacy Network costs include amounts incurred under a network
     infrastructure support agreement with Prodigy. These costs include all
     expenses incurred in connection with the operation of the Legacy Network,
     including facility fees, line charges, personnel costs, occupancy costs and
     equipment maintenance costs.
 
          Property and Equipment. Property and equipment are stated at cost.
     Depreciation and amortization of new property and equipment, including
     assets under capital leases, is provided upon installation using the
     straight-line method over the estimated useful lives of three to five
     years. Previously used equipment is depreciated over its estimated useful
     life of nine months to three years.
 
          Long-Lived Assets. The Company reviews for the impairment of
     long-lived assets whenever events or changes in circumstances indicate that
     the carrying amount of an asset may not be recoverable. The carrying amount
     of a long-lived asset is considered impaired when anticipated undiscounted
     cash flows expected to result from the use of the asset and its eventual
     disposition are less than its carrying amount. The Company believes that no
     material impairment exists at December 31, 1997.
 
          Income Taxes. Deferred tax assets and liabilities are determined based
     on the temporary differences between the financial statement carrying
     amounts and the tax bases of assets and liabilities using the enacted tax
     rates in effect in the years in which the differences are expected to
     reverse. In estimating

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     future tax consequences, all expected future events are considered other
     than enactments of changes in the tax law or rates.
 
          Cash and Cash Equivalents. The Company considers highly liquid
     investments with an original maturity of three months or less from the date
     of purchase to be classified as cash and cash equivalents. The restricted
     cash equivalent is a three-month time deposit held as collateral on a
     letter of credit.
 
          Concentration of Credit Risk. Financial instruments which potentially
     subject the Company to concentration of credit risk are primarily cash and
     cash equivalents and receivables. The Company's cash investment policies
     limit investments to short-term, investment grade instruments with quality
     financial institutions. The Company's revenues and its trade receivable
     balance for the period ended December 31, 1997 were derived solely from
     services provided to Prodigy, the Company's sole customer during this
     period. Any interruption of this relationship could adversely affect the
     Company. Management believes that the risk of incurring material losses
     related to these credit risks are remote.
 
          Net Loss Per Share In February 1997, Statement of Financial Accounting
     Standards No. 128 ("FAS 128") Earnings Per Share was issued. FAS 128 is
     effective for both interim and annual periods ending after December 15,
     1997. The Company adopted the pronouncement for the period ended December
     31, 1997. FAS 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. At December 31, 1997, options to acquire
     1,880,000 shares of common stock at the exercise price of $0.625 and
     warrants to purchase 5,000,000 shares of common stock at $0.625 were not
     included in the computation of diluted earnings per share because their
     effect is anti-dilutive.
 
          Stock-Based Compensation. The Company has adopted Statement of
     Financial Accounting Standards No. 123 ("FAS 123"), Accounting for
     Stock-Based Compensation, for disclosure purposes. Under FAS 123, the
     Company measures compensation expense for its stock-based employee
     compensation plan using the intrinsic value method prescribed in APB No.
     25, Accounting for Stock Issued to Employees, and provides disclosure of
     the effect of net income as if the fair value-based method prescribed in
     FAS 123 has been applied in measuring compensation expense.
 
          Fair Values of Financial Instruments. Due to the short-term nature of
     the Company's financial instruments, as well as their interest rates and
     terms, management believes the carrying value of the Company's assets and
     liabilities approximates their fair values.
 
          Use of Estimates. The preparation of the Company's financial
     statements in conformity with generally accepted accounting principles
     requires management to make estimates and assumptions that affect the
     reported amounts of assets, liabilities, revenues and expenses, as well as
     disclosures of contingent assets and liabilities. Because of inherent
     uncertainties in this process, actual future results could differ from
     those expected at the reporting date. Management believes the estimates are
     reasonable.
 
          New Accounting Pronouncements. In June 1997, the Financial Accounting
     Standards Board issued Statement of Financial Accounting Standards No. 130,
     Reporting Comprehensive Income, and No. 131, Disclosures about Segments of
     an Enterprise and Related Information. In February 1998, the Board issued
     No. 132, Employers' Disclosures about Pensions and Other Postretirement
     Benefits. The Company will adopt these statements in 1998. The Company does
     not expect their adoption to have a material effect on the Company's
     financial position or results of operations.

2. PRODIGY TRANSACTIONS
 
     On June 24, 1997, the Company entered a four-year Full Service Agreement
with Prodigy, in which the Company agreed to provide certain network services to
Prodigy from July 1, 1997 through June 30, 2001 for a price per hour of usage as
stipulated, subject to minimum and maximum amounts. Monthly minimum service
commitments set each year under this four-year contract range from $3,000 to
$4,500. Monthly maximum service commitments are based on average usage per
subscriber and the number of subscribers. Prodigy may terminate the Full Service
Agreement without payment in an event of default by the Company; such defaults
include documented failures (without cure) to meet certain network performance
standards. The Company is subject to several financial covenants through June
30, 1999 under this agreement, including the maintenance of at least $5,000 in
net tangible worth. The agreement also allows Prodigy to terminate its
arrangement with the Company at any time upon the payment of a termination
charge.
 
     Also on June 24, 1997, the Company entered into a Definitive Agreement with
Prodigy pursuant to which the Company acquired selected data transmission
equipment from Prodigy. In consideration for the equipment, the Company assumed
approximately $5,900 in equipment lease obligations and other liabilities.
 
     The Company also entered into an agreement with Prodigy in which Prodigy
agreed to provide certain network infrastructure support for the Company for the
period July 1, 1997 through December 31, 1997. The Company incurred expenses of
$25,804 (which includes $463 of severance costs) under this agreement during
1997, of which $5,194 remained payable to Prodigy at December 31, 1997. These
services included the services of selected Prodigy employees and services
provided under vendor arrangements related to the Prodigy network
infrastructure. The costs of these services and other reasonable and customary
charges incurred by Prodigy in connection with the continued operations of the
network during this transition period are reimbursable by the Company. The
Company assumed no contractual liabilities of any services related to Prodigy's
existing network infrastructure as part of the transition agreement.

     Capital leases require payments on a monthly basis over periods ranging
from 24 to 48 months, with implicit interest rates of 9% to 12%.
 
     In December 1997, the Company borrowed $1,000 from a stockholder. The
unsecured note has a stated rate of interest of 9.75% and provides for monthly
interest payments beginning February 1, 1998, with the principal due on demand
after December 31, 1998, and maturing December 31, 2002.
 
5. INCOME TAXES
 
     A provision for income taxes for the period ended December 31, 1997 has not
been recognized as the Company had operating losses for both tax and financial
reporting purposes. Due to the uncertainty surrounding the timing of realizing
the benefits of its favorable tax attributes in future tax returns, the Company
has recorded a full valuation allowance against its otherwise recognizable net
deferred tax asset.
 
     Deferred tax assets at December 31, 1997 consist of the following:

</TABLE>
 
     The Company's net operating loss carryforward of approximately $9,500
expires in 2012. Certain changes in ownership of the Company could result in
limitations on the Company's ability to utilize the losses.
 
6. COMMITMENTS AND CONTINGENCIES
 
     The Company leases office space, equipment facilities and equipment under
noncancelable operating and capital leases expiring through the year 2002. Rent
expense for noncancelable operating leases amounted to $218 in 1997.
 
     The Company leases telephone lines ("line costs") from competitive local
exchange suppliers, interchange carriers and long distance telephone companies
primarily for access and transport purposes. These line costs are leased under
both cancelable and noncancelable operating leases over periods up to three
years and are included in Legacy Network costs on the statement of operations.
Certain cancellation charges could become applicable upon termination of a
number of these agreements. Line costs incurred during the period from inception
(March 5, 1997) to December 31, 1997 comprise a substantial portion of the
Legacy Network costs.

performance under a certain capital lease obligation. This letter of credit is
secured by the restricted cash equivalent shown on the balance sheet.
 
     As of December 31, 1997, the Company has an agreement with a
telecommunications company to pay a minimum of $1,266 for network installation
services over a period ending June 30, 1998. Total commitments remaining under
this agreement approximated $1,160 at December 31, 1997.
 
7. COMMON STOCK EXCHANGE
 
     The Company effected a 1-for-100 stock exchange on June 3, 1997 and a
1-for-10 stock exchange on August 8, 1997. All share amounts included in these
financial statements have been adjusted to reflect the effect of the stock
exchanges.
 
8. STOCK OPTIONS
 
     The Company's 1997 Incentive Share Plan (the Plan) provides that options to
purchase up to 20,000,000 shares of common stock may be granted to certain
directors, employees or consultants of the Company. Options under the Plan have
a term of ten years and are granted with an exercise price equivalent to market
value at the date of grant. Individual option grants vest over time, based upon
a schedule approved by the Board of Directors, which is generally four years.
All of the Company's common stock options vest automatically upon a change in
control of the Company, as defined.
 
     The following summarizes the activity for the Plan:

     The Company has adopted the disclosure-only provisions of FAS No. 123.
Accordingly, no compensation cost has been recognized for fixed options granted
to Company employees. Had compensation cost for the Company's stock option plan
been determined based on the fair value at the grant date for awards in 1997
consistent with the provisions of SFAS No. 123, the Company's pro forma net loss
would have been as follows (in thousands):

     Options granted in 1997 had weighted-average fair values of $0.077. The
Company used the minimum value method to estimate the fair values of options for
the above pro forma information. For purposes of the minimum value method, the
Company used average U.S. government security interest rates for its risk-free
interest rates, assumed no volatility or future dividends and assumed expected
life of the options of five years in 1997.
 
9. RELATED PARTY TRANSACTIONS
 
     The Company's chairman of the Board of Directors (the Chairman), who is
also a shareholder of the Company, is the Chief Technical Officer and assistant
vice chairman and stockholder of a vendor (the Vendor) from which the Company
purchased approximately $16,500 in equipment through December 31, 1997.
Remaining commitments pursuant to a purchase agreement with the vendor
approximate $9,045 at December 31, 1997.
 
     The Company also retained the Vendor to perform assembly services related
to the deployment of network equipment to the field. The Company incurred
approximately $1,500 for these services of which approximately $990 were
expensed in 1997.
 
     A stockholder (an affiliate of the Chairman) has agreed to lend up to
$10,000 to the Company for the purchase of certain network equipment. As of
December 31, 1997, this affiliate had loaned $1,000 to the Company. During the
three months ended March 31, 1998 the affiliate made further advances under this
agreement (Note 10).
 
     In September 1997, a wholly-owned subsidiary of a major stockholder of
Prodigy, the Company's sole customer, purchased 20,000,000 shares of the Company
for $0.625 per share and paid $0.1 for a warrant to purchase an additional
5,000,000 shares of the Company through September 18, 1998 for $0.625 per share.

1. BASIS OF PRESENTATION
 
     The condensed balance sheet of Splitrock Services, Inc. (the Company) as of
December 31, 1997 and March 31, 1998, the condensed statements of operations for
the three months ended March 31, 1998, the condensed statement of stockholders'
equity for the three months ended March 31, 1998 and the condensed statements of
cash flows for the three months ended March 31, 1998 are unaudited. They do not
include all information and notes required by generally accepted accounting
principles for complete financial statements. In the opinion of management, such
financial statements include all adjustments, consisting only of normal
recurring adjustments necessary for a fair presentation of financial position,
results of operations, and cash flows for the periods presented.
 
     Condensed financial statements for the period from Inception (March 5,
1997) through March 31, 1997 are not included for comparative purposes as the
balances were insignificant and the related statements are not considered
meaningful.
 
     The condensed balance sheet at December 31, 1997 was derived from audited
financial statements, but does not include all disclosures required by generally
accepted accounting principles. The financial statements presented herein should
be read in connection with the Company's financial statements as of December 31,
1997 and for the period from Inception (March 5, 1997) to December 31, 1997.
 
2. BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES
 
     The Company was incorporated in Texas on March 5, 1997 and reincorporated
in Delaware on May 8, 1998.
 
     The Company was formed to build a nationwide, facilities-based
telecommunications network with the goal of providing telecommunications
services on an advanced nationwide network. The Company has designed and is in
the process of deploying a network based on Asychronous Transfer Mode (ATM)
technology which it believes will provide high quality communications services
on a flexible multi-service platform.
 
     During 1997, the Company launched a major network rebuilding program based
on ATM technology. This program was organized in two phases. As of March 31,
1998, the Company was in Phase I of the network build which encompassed the
buildout of the nationwide ATM backbone and operational points of presence in 70
metropolitan areas.
 
     In addition to the development of a new telecommunications network and
implementing Phase I, the Company has been engaged in recruiting management and
operational personnel and structuring financing for the Company's operations.
 
     Upon completion of the network build, the Company will offer basic
transport services to other internet service providers and will be positioned to
provide other value-added data, voice and video products to business customers.
 
     Revenue Recognition. The Company recognizes revenue as services are
provided under its agreement with its customer. Prodigy was the Company's only
customer through March 31, 1998. Prodigy may terminate its agreement with the
Company without payment in the event of certain defaults by the Company,
including documented failures (without cure) to meet certain network performance
standards.
 
     Property and Equipment. Property and equipment are stated at cost.
Depreciation and amortization of new property and equipment, including assets
under capital leases, is provided upon installation using the

            NOTES TO CONDENSED FINANCIAL INFORMATION -- (CONTINUED)
                       THREE MONTHS ENDED MARCH 31, 1998
           (AMOUNTS IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)

straight-line method over their estimated useful lives of three to five years.
Previously used equipment is depreciated over its estimated useful life of nine
months to three years.
 
     Net Loss Per Share. In February 1997, Financial Accounting Standard No. 128
("FAS 128") Earnings Per Share was issued. FAS 128 is effective for both interim
and annual periods ending after December 15, 1997. The Company adopted the
pronouncement for the period ended December 31, 1997. FAS 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. At March 31, 1998, options to
acquire 2,095,500 shares of common stock at the exercise price of $0.625 and
warrants to purchase 5,000,000 shares of common stock at $0.625 were not
included in the computation of diluted earnings per share because the Company
recorded a loss from operations and a net loss, which would have resulted in
anti-dilution.
 
     Comprehensive Income. Effective January 1, 1998, the Company adopted
Statement of Financial Accounting Standards No. 130, Reporting Comprehensive
Income. This Statement establishes standards for reporting and display of
comprehensive income and its components. For the three-month period ended March
31, 1998 comprehensive net loss, as determined under Statement No. 130, was the
same as net loss as reported in the Statement of Operations.
 
     New Accounting Pronouncement. On June 15, 1998, the Financial Accounting
Standards Board (FASB) issued Statement of Financial Accounting Standards No.
133, Accounting for Derivative Instruments and Hedging Activities (FAS 133). FAS
133 is effective for all fiscal quarters of all fiscal years beginning after
June 15, 1999 (January 1, 2000 for the Company). FAS 133 requires that all
derivative instruments be recorded on the balance sheet at their fair value.
Changes in the fair value of derivatives are recorded each period in current
earnings or other comprehensive income, depending on whether a derivative is
designated as part of a hedge transaction and, if it is, the type of hedge
transaction. Management of the Company anticipates that, due to its expected
limited or no use of derivative instruments, the adoption of FAS 133 will not
have a significant effect on the Company's results of operations or its
financial position.

     Components of indebtedness are summarized as follows:

     In January 1998, the Company borrowed $3,000 from a stockholder. The note
has a stated rate of interest of 9.75% and provides for monthly interest
payments beginning March 1, 1998, with the principal due on demand after
December 31, 1998. The note matures on December 31, 2002. The Company borrowed
$2,000 from the same stockholder in March 1998 on terms substantially the same
as the previous note.

     In March 1998, the Company exercised its early purchase option under a
capital lease arrangement with AT&T Capital Corporation. The Company paid $3,455
to liquidate the obligation.
 
4. INCOME TAXES
 
     A provision for income taxes for the three months ended March 31, 1998 has
not been recognized as the Company had operating losses for both tax and
financial reporting purposes. Certain changes in the ownership of the Company
could result in limitations on the Company's ability to utilize the losses.
 
5. SUBSEQUENT EVENTS
 
     In April 1998, the Company entered into an agreement with a
telecommunications equipment supplier to obtain equipment and services for the
deployment of 99 points of presence. The Company obtained a $5,000 credit
facility from the same company (the Lender) to be used solely for the purchase
of such equipment and services. Borrowings on the credit facility bear an annual
rate of interest at 11%, with interest payable monthly, commencing on June 1,
1998. All principal and accrued interest is due the earlier of (i) the date the
Company sells any of its equity securities or debt instruments (other than
issuances to officers, directors, employees or consultants in the ordinary
course of business) and the net proceeds to the Company are in an aggregate
amount equal to or greater than the then outstanding principal amount of the
credit facility or (ii) October 30, 1998. The Lender may extend the maturity to
April 1, 2001 subject to the issuance of a transferable, noncallable stock
purchase warrant giving the Lender the right to purchase 1,111,000 shares of the
Company's common stock at an exercise price based upon the lower of $1.00 per
share or the lowest price at which shares of common stock are issued during the
period from the date the warrants are issued to the date the warrants expire
(eight years following issuance). Upon extension, the credit facility will have
a stated rate of interest of LIBOR plus 5.75% and a default rate of interest on
all amounts not paid when due of an additional 2%. The extended facility
provides for monthly interest payments through January 2, 1999, with the
principal due in ten equal consecutive quarterly installments commencing on
January 2, 1999.
 
     A director of the Company exercised an option to purchase one million
shares of Company common stock for $1,100 in June 1998.
 
     In June 1998, the Company borrowed $5,000 from a stockholder. The note
bears substantially the same terms as the previous stockholder notes.
 
     On July 21, 1998, the Company sold 261,000 Units consisting of $261,000
principal amount of 11 3/4% Senior Notes due 2008 and Warrants to purchase
2,642,613 shares of common stock (the Offering). In connection with the
Offering, the Company repaid the amount outstanding, approximately $1,500, under
the $5,000 credit facility discussed above and refinanced $11,000 of
indebtedness owed to a stockholder. In connection with the refinancing, the
stockholder purchased 11,000 Units in the Offering. The net proceeds to the
Company, after expenses, approximated $239,000.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Splitrock is incorporated under the laws of the State of Delaware. Section
145 of the General Corporation Law of the State of Delaware ("Section 145")
provides that a Delaware corporation may indemnify any person who was or is a
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, by reason of the fact that such person is or was an officer,
director, employee or agent of such corporation, or is or was serving at the
request of such corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or enterprise, including an
employee benefit plan. The indemnity may include expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by such person in connection with such action, suit or proceeding,
provided that such person acted in good faith and in a manner he reasonably
believed to be in or not opposed to the corporation's best interests and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
that his conduct was unlawful, except that no indemnification shall be made in
connection with any action or suit by or in the right of the corporation to
procure a judgment in its favor 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 or the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
that such court deems proper. 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.
 
     Section 145 also provides that to the extent that a director, officer,
employee or agent of the corporation has been successful on the merits or
otherwise in defense of any action, suit or proceeding referred to above, or in
defense of any claim, issue or matter therein, the corporation must indemnify
him against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith.
 
     Section 145 further provides that any indemnification (unless ordered by a
court) must be made only as authorized in the specific case upon a determination
that indemnification of the director, officer, employee or agent is proper in
the circumstances because he has met the applicable standard of conduct set
forth above. Section 145 also provides that expenses (including attorneys' fees)
incurred by an officer or director in defending or settling any civil, criminal,
administrative or investigative action, suit or proceeding may be paid by the
corporation in advance of the final disposition of such action, suit or
proceeding, upon receipt of an undertaking by or on behalf of such director or
officer to repay such amount if it is ultimately determined that he is not
entitled to be indemnified by the corporation. Additionally, Section 145
provides that the indemnification and advancement of expenses provided by, or
granted pursuant to, Section 145 shall not exclude any other rights to which a
person seeking indemnification or advancement of expenses may be entitled under
any bylaw, agreement, vote of stockholders or disinterested directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding such office.
 
     Article IX of Splitrock's Certificate of Incorporation requires Splitrock
to indemnify Splitrock's directors and officers to the extent permitted under
Section 145.
 
     Article VII of Splitrock's Bylaws also provides that Splitrock shall
indemnify any person who was or is a 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, by reason of the fact that he
is or was a director or officer of Splitrock, or is or was serving at the
request of Splitrock as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust, or other enterprise, in
accordance with provisions corresponding to Section 145. Further, Splitrock's
Bylaws provide that any person, other than an officer or director, who was or is
a party or is threatened to be made a party to any threatened, pending, or
completed
                                      II-1
<PAGE>   144
 
action, suit or proceeding, whether civil, criminal, administrative, or
investigative, by reason of the fact that he is or was an employee or agent of
Splitrock, or was serving at the request of Splitrock as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust, or
other enterprise, and who desires indemnification shall make written application
for such indemnification to the Board of Directors for its determination that
indemnification is appropriate, and if so, to what extent.
 
     Section 145 further provides that a corporation may purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such, whether or not the corporation would have the authority to indemnify him
against such liability and expenses under the provisions described in the
preceding paragraphs. Splitrock maintains liability insurance covering its
directors and officers.
 
     Section 102(b)(7) of the General Corporation Law of the State of Delaware
permits a Delaware corporation to include a provision in its Certificate of
Incorporation eliminating or limiting the personal liability of a director to
the corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except (i) for any breach of the director's duty of loyalty
to the corporation or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) pursuant to Section 174 of the General Corporation Law of the State of
Delaware (providing for liability of directors for unlawful payment of dividends
or unlawful stock purchases or redemptions), or (iv) for any transaction from
which the director derived an improper personal benefit. Article VIII of
Splitrock's Certificate of Incorporation eliminates liability of directors of
Splitrock to Splitrock or its shareholders for monetary damages for breach of
fiduciary duty to the extent permitted by Section 102(b)(7) of the General
Corporation Law of the State of Delaware.
 
     The foregoing discussion is qualified in its entirety by reference to the
General Corporation Law of the State of Delaware and Splitrock's Certificate of
Incorporation and Bylaws.
 
     Splitrock's Bylaws also provide that Splitrock may indemnify, to the extent
of the provisions set forth therein, any person other than an officer or
director who was or is a 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, by reason of the fact that he is or
was an employee or agent of Splitrock, or was serving at the request of
Splitrock as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, if such person makes
written application for such indemnification to the Splitrock Board and the
Splitrock Board determines that indemnification is appropriate and the extent
thereof.
 
     Splitrock's Bylaws further provide that the indemnification described
therein is not exclusive, and shall not exclude any other rights to which the
person seeking to be indemnified may be entitled under statute, any bylaw,
agreement, vote of shareholders or disinterested directors, or otherwise, both
as to action in his official capacity and to his action in another capacity
while holding such office.
 
     The above discussion of Section 145 and of Splitrock's Certificate of
Incorporation and Bylaws is not intended to be exhaustive and is respectively
qualified in its entirety by such statute, the Certificate of Incorporation and
the By-laws.

ITEM 22. UNDERTAKINGS
 
     (i) The undersigned registrant hereby undertakes that prior to any public
reoffering of the securities registered hereunder through use of a prospectus
which is a part of this registration statement, by any person or party who is
deemed to be an underwriter within the meaning of Rule 145(c), such reoffering
prospectus will contain the information called for by the applicable
registration form with respect to reofferings by persons who may be deemed
underwriters, in addition to the information called for by the other Items of
the applicable form. Every prospectus (i) that is filed in accordance with the
undertaking above or (ii) that purports to meet the requirements of section
10(a)(3) of the Securities Act and is used in connection with an offering of
securities subject to Rule 415, will be filed as a part of an amendment to the
registration statement and will not be used until such amendment is effective,
and that, for purposes of determining liability under the Securities Act, each
such post-effective amendment 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.
 
     (ii) The undersigned registrant hereby undertakes to respond to requests
for information that is incorporated by reference into the prospectus pursuant
to Item 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
     (iii) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
 
     (iv) 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 described in Item 20 above, or
otherwise, the registrant has been advised that in the opinion of the 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
 
                                      II-4
<PAGE>   147
 
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 appropriate
jurisdiction the question whether such indemnification by it is against policy
as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

"Company"), proposes to issue and sell 261,000 units (the "Units"), each Unit
consisting of $1,000 principal amount of the Company's 11 3/4% Senior Notes due
2008 (the "Notes") and one warrant (a "Warrant") to purchase 10.124954 shares
of common stock, par value $.001 per share ("Common Stock"), of the Company.
The Notes will be issued pursuant to an Indenture to be dated as of July 24,
1998 (the "Indenture") between the Company and the Bank of Montreal Trust
Company, as trustee (the "Trustee") and will be guaranteed on a senior,
unsecured basis by each of the Company's future Restricted Subsidiaries (as
defined in the Indenture) that incurs indebtedness (the "Subsidiary
Guarantors").  The Warrants will be issued pursuant to a warrant agreement (the
"Warrant Agreement") between the Company and the Bank of Montreal Trust
Company, as Warrant Agent (the "Warrant Agent").  The Units, the Notes and the
Warrants are collectively referred to herein as the "Securities".  The Company
hereby confirms its agreement with Chase Securities Inc. ("CSI" or the "Initial
Purchaser") concerning the purchase of the Units from the Company by the
Initial Purchaser.

                 The Securities will be offered and sold to the Initial
Purchaser without being registered under the Securities Act of 1933, as amended
(the "Securities Act"), in reliance upon an exemption therefrom.  The Company
has prepared a preliminary offering memorandum dated June 29, 1998 (the
"Preliminary Offering Memorandum") and will prepare an offering memorandum
dated the date hereof (the "Offering Memorandum") setting forth information
concerning the Company and the Securities.  Copies of the Preliminary Offering
Memorandum have been, and copies of the Offering Memorandum will be, delivered

Agreement.  Any references herein to the Preliminary Offering Memorandum and
the Offering Memorandum shall be deemed to include all amendments and
supplements thereto, unless otherwise noted.  The Company hereby confirms that
it has authorized the use of the Preliminary Offering Memorandum and the
Offering Memorandum in connection with the offering and resale of the
Securities by the Initial Purchaser in accordance with Section 2.

                 Holders of the Notes (including the Initial Purchaser and its
direct and indirect transferees) will be entitled to the benefits of an
Exchange and Registration Rights

Agreement, substantially in the form attached hereto as Annex A (the
"Registration Rights Agreement"), pursuant to which the Company will agree to
file with the Securities and Exchange Commission (the "Commission") (i) a
registration statement under the Securities Act (the "Exchange Offer
Registration Statement") registering an issue of senior notes of the Company
(the "Exchange Notes") which are identical in all material respects to the
Notes (except that the Exchange Notes will not contain terms with respect to
transfer restrictions) and (ii) under certain circumstances, a shelf
registration statement pursuant to Rule 415 under the Securities Act (the
"Shelf Registration Statement").

                 Holders of the Warrants will be entitled to the benefit of
certain registration rights under the Warrant Agreement pursuant to which the
Company will agree to file with the Commission (i) a shelf registration
statement (the "Warrant Shelf Registration Statement") under the Securities Act
covering the resale of the Warrants and (ii) a shelf registration statement
under the Securities Act covering the issuance of shares of Common Stock to
Holders of the Warrants upon their exercise.

                 Pursuant to an escrow and disbursement agreement (the "Escrow
Agreement") the Company will deposit with The Chase Manhattan Bank, as escrow
agent (the "Escrow Agent"), an amount in cash or Temporary Cash Investments
that, together with the interest received thereon, will be sufficient to pay
when due the first four semi-annual interest payments on the Notes.

                 Capitalized terms used but not defined herein shall have the
meanings given to such terms in the Offering Memorandum.

                 1.  Representations, Warranties and Agreements of the Company.

         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary in order to make the statements
         therein, in the light of the circumstances under which they were made,

         Purchaser's Information").

                 (b)  Each of the Preliminary Offering Memorandum and the
         Offering Memorandum, as of its respective date, contains all of the

         purchaser pursuant to Rule 144A(d)(4) under the Securities Act.

                 (c)  Assuming the accuracy of the representations and
         warranties of the Initial Purchaser contained in Section 2 and its
         compliance with the agreements set forth therein, it is not necessary,

         Initial Purchaser in the manner contemplated by this Agreement and the

         existing as a corporation in good standing under the laws of Delaware,
         is duly qualified to do business and is in good standing as a foreign

         property or the conduct of its business requires such qualification,
         and has all power and authority necessary to own or hold its
         properties and to conduct the business in which it is engaged, except
         where the failure to so qualify or have such power or authority would
         not, singularly or in the aggregate, have a material adverse effect on
         the condition (financial or otherwise), results of operations,
         business or prospects of the Company (a "Material Adverse Effect").

                 (e)  As of the Closing Date, the Company will have an
         authorized capitalization as set forth in the Offering Memorandum
         under the heading "Capitalization"; all of the outstanding shares of
         capital stock of the Company have been duly and validly authorized and
         issued and are fully paid and non-assessable; the capital stock of the
         Company conforms in all material respects to the description thereof
         contained in the Offering Memorandum; when the Units are delivered and
         paid for pursuant to this Agreement on the Closing Date, the Warrants
         will be convertible into shares of Common Stock ("Underlying Shares")
         in accordance with their terms; and the Underlying Shares initially
         issuable upon conversion of such Warrants have been duly and validly
         authorized and reserved for issuance upon such conversion and, when
         issued upon such conversion, will be validly issued, fully paid and
         nonassessable.  The Company does not have any subsidiaries.

                 (f)  The Company has full right, power and authority to
         execute and deliver this Agreement, the Indenture, the Registration
         Rights Agreement, the Escrow Agreement, the Notes, the Warrants and
         the Warrant Agreement (collectively, the "Transaction Documents") and

         and validly taken.

                 (g)  This Agreement has been duly authorized, executed and

         agreement of the Company.

         authorized by the Company and, when duly executed and delivered in
         accordance with its terms by each of the parties thereto, will
         constitute a valid and legally binding agreement of the Company
         enforceable against the Company  in accordance with its terms, except
         to the extent that such enforceability may be limited by applicable
         bankruptcy, insolvency, fraudulent conveyance, reorganization,
         moratorium and other similar laws affecting creditors' rights
         generally and by general equitable principles (whether considered in a
         proceeding in equity or at law).

                 (i)  The Indenture has been duly authorized by the Company
         and, when duly executed and delivered in accordance with its terms by
         each of the parties thereto, will constitute a valid and legally
         binding agreement of the Company enforceable

         Company and, when duly executed and delivered in accordance with its
         terms by each of the parties thereto, will constitute a valid and
         legally binding agreement of the Company enforceable against the
         Company in accordance with its terms, except to the extent that such
         enforceability may be limited by applicable bankruptcy, insolvency,
         fraudulent conveyance, reorganization, moratorium and other similar
         laws affecting creditors' rights generally and by general
         equitable principles (whether considered in a proceeding in equity or

         when duly executed, authenticated, issued and delivered as provided in
         the Indenture and paid for as provided herein, will be duly and

         Offering Memorandum, except where the failure to possess or make the
         same would not, singularly or in the aggregate, have a Material
         Adverse Effect, and the Company has not received notification of any
         revocation or modification of any such license, certificate,

         foreign income and franchise tax returns required to be filed through
         the date hereof and have paid all taxes due thereon, and no tax

         to have) a Material Adverse Effect.

                 (w) The Company is not (i) an "investment company" or a

         Company, in each case free and clear of all liens, encumbrances,
         claims and defects and imperfections of title except such as (i) do
         not materially interfere with the use made and proposed to be made of
         such property by the Company or (ii) could not reasonably be expected

         amended from time to time (the "Code")) or "accumulated funding
         deficiency" (as defined in Section 302 of ERISA) or any of the events
         set forth in Section 4043(b) of ERISA (other than events with respect
         to which the 30-day notice requirement under Section 4043 of ERISA has
         been waived) has occurred with respect to any employee benefit plan of
         the Company which could reasonably be expected to have a Material
         Adverse Effect; each such employee benefit plan is in compliance in
         all material respects with applicable law, including ERISA and the
         Code; the Company has not incurred and does not expect to incur
         liability under Title IV of ERISA with respect to the termination of,
         or withdrawal from, any pension plan for which the Company would have
         any liability; and each such pension plan that is intended to be
         qualified under Section 401(a) of the Code is so qualified in all
         material respects and nothing has occurred, whether by action or by
         failure to act, which could reasonably be expected to cause the loss
         of such qualification.

                 (dd) There has been no storage, generation, transportation,
         handling, treatment, disposal, discharge, emission or other release of
         any kind of toxic or other wastes or other hazardous substances by,

         Company, any other entity (including any predecessor) for whose acts
         or omissions the Company is or could reasonably be expected to be
         liable) upon any of the property now or previously owned or leased by
         the Company, or upon any other property, in violation of any statute
         or any ordinance, rule, regulation, order, judgment, decree or permit
         or which would, under any statute or any ordinance, rule (including
         rule of common law), regulation, order, judgment, decree or permit,
         give rise to any liability, except for any violation or liability that
         could not reasonably be expected to have, singularly or in the
         aggregate with all such violations and liabilities, a Material Adverse
         Effect; and there has been no disposal, discharge, emission or other
         release of any kind onto such property or into the environment
         surrounding such property of any toxic or other wastes or other
         hazardous substances with respect to which the Company has knowledge,
         except for any such disposal, discharge, emission or other release of
         any kind which could not reasonably be expected to have, singularly or
         in the aggregate with all such discharges and other releases, a
         Material Adverse Effect.

                 (ee)  Neither the Company nor, to the best knowledge of the
         Company, any director, officer, agent, employee or other person

         Act of 1977; or (iv) made any bribe, rebate, payoff, influence
         payment, kickback or other unlawful payment.

                 (ff)  On and immediately after the Closing Date, the Company
         (after giving effect to the issuance of the Securities and to the
         other transactions related thereto as described in the Offering
         Memorandum) will be Solvent.  As used in this paragraph, the term
         "Solvent" means, with respect to a particular date, that on such date
         (i) the
<PAGE>   9
                                                                               9

         present fair market value (or present fair saleable value) of the
         assets of the Company is not less than the total amount required to
         pay the probable liabilities of the Company on its total existing
         debts and liabilities (including contingent liabilities) as they
         become absolute and matured, (ii) the Company is able to realize upon
         its assets and pay its debts and other liabilities, contingent
         obligations and commitments as they mature and become due in the
         normal course of business, (iii) assuming the sale of the Securities
         as contemplated by this Agreement and the Offering Memorandum, the
         Company is not incurring debts or liabilities beyond its ability to
         pay as such debts and liabilities mature and (iv) the Company is not
         engaged in any business or transaction, and is not about to engage in
         any business or transaction, for which its property would constitute
         unreasonably small capital after giving due consideration to the
         prevailing practice in the industry in which the Company is engaged.
         In computing the amount of such contingent liabilities at any time, it
         is intended that such liabilities will be computed at the amount that,
         in the light of all the facts and circumstances existing at such time,
         represents the amount that can reasonably be expected to become an
         actual or matured liability.

                 (gg)  Except for the Warrants and except as otherwise
         described in the Offering Memorandum, there are no outstanding
         subscriptions, rights, warrants, calls or options to acquire, or
         instruments convertible into or exchangeable for, or agreements or
         understandings with respect to the sale or issuance of, any shares of
         capital stock of or other equity or other ownership interest in the
         Company.

                 (hh) The Company does not own any "margin securities" as that
         term is defined in Regulation U of the Board of Governors of the
         Federal Reserve System (the "Federal Reserve Board"), and none of the
         proceeds of the sale of the Securities will be used, directly or
         indirectly, for the purpose of purchasing or carrying any margin
         security, for the purpose of reducing or retiring any indebtedness
         which was originally incurred to purchase or carry any margin security
         or for any other purpose which might cause any of the Securities to be
         considered a "purpose credit" within the meanings of Regulation T, U
         or X of the Federal Reserve Board.

                 (ii) The Company is not a party to any contract, agreement or
         understanding with any person that would give rise to a valid claim
         against the Company or the Initial Purchaser for a brokerage
         commission, finder's fee or like payment in connection with the
         offering and sale of the Securities.

                 (jj) The Securities satisfy the eligibility requirements of
         Rule 144A(d)(3) under the Securities Act.

                 (kk) Neither the Company nor any of its affiliates has,
         directly or through any agent, sold, offered for sale, solicited
         offers to buy or otherwise negotiated in respect of, any security (as
         such term is defined in the Securities Act), which is or will be
         integrated with the sale of the Securities in a manner that would
         require registration of the Securities under the Securities Act.

                 (ll) None of the Company or any of its affiliates or any other
         person acting on its or their behalf has engaged, in connection with
         the offering of the Securities, in any form of general solicitation or
         general advertising within the meaning of Rule 502(c) under the
         Securities Act.

                 (mm) There are no securities of the Company registered under
         the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
         or listed on a national securities exchange or quoted in a U.S.
         automated inter-dealer quotation system.

                 (nn) The Company has not taken nor will it take, directly or
         indirectly, any action prohibited by Regulation M under the Exchange
         Act in connection with the offering of the Securities.

                 (oo) No forward-looking statement (within the meaning of
         Section 27A of the Securities Act and Section 21E of the Exchange Act)
         contained in the Preliminary Offering Memorandum or the Offering
         Memorandum has been made or reaffirmed without a reasonable basis or
         has been disclosed other than in good faith.

                 (pp) The Company does not do business with the government of
         Cuba or with any person or affiliate located in Cuba within the
         meaning of Florida Statutes Section 517.075.

                  (qq)  The Company is currently evaluating its operations and
         systems to determine the risk of computer hardware and software used
         by it becoming unable to recognize and properly execute date-sensitive
         functions involving certain dates prior to and any dates after
         December 31, 1999 (the "year-2000 issue"), and has determined that
         such risk will be remedied on a timely basis without material expense
         and will not have a Material Adverse Effect; and the Company believes,
         after due inquiry of its customers and certain suppliers, that each
         customer, supplier and financial service organization used or serviced

         a supplement or amendment to the Offering Memorandum so that the
         Offering Memorandum (as so amended or supplemented) would not include
         any untrue statement of a material fact and would not omit to state a
         material fact required to be stated therein or necessary in order to
         make the statements therein, in
<PAGE>   17
                                                                              17

         the light of the circumstances under which they were made, not
         misleading,  (C) as of the Closing Date, the representations and
         warranties of the Company in this Agreement are true and correct, the

         statements contained in the Offering Memorandum, there has been no
         material adverse change in the financial position or results of
         operations of the Company, or any change, or any development involving
         a prospective change, in or affecting the condition (financial or
         otherwise), results of operations, business or prospects of the
         Company, taken as a whole, (E) they have read the covenants and
         conditions (i) in the Indenture relating to the issuance of the Notes

         the Warrants by the Company and the countersignature and delivery of

         and (ii), the related definitions, (F) they are authorized to examine
         and have access to the relevant records and accounts of the Company
         and are conversant with the corporate proceedings and documents
         relating to the authorization and issuance of the Units, Notes, and
         Warrants, (G) in their opinion they have made such examination or
         investigation as is necessary to enable them to express an informed
         opinion as to whether or not the covenants and conditions referred to
         in the Indenture and the Warrant Agreement referred to in clause (E)
         above have been complied with, and (H) in their opinion all such
         covenants and conditions have been complied with.

                 (i)  The Initial Purchaser shall have received a counterpart
         of the Registration Rights Agreement which shall have been executed
         and delivered by a duly authorized officer of the Company.

                 (j)  The Indenture shall have been duly executed and delivered
         by the Company and the Trustee, and the Notes shall have been duly
         executed and delivered by the Company and duly authenticated by the

         the Offering Memorandum, such amendment or supplement shall have been
         prepared, the Initial Purchaser shall have been given a reasonable
         opportunity to comment thereon, and copies thereof shall have been
         delivered to the Initial Purchaser reasonably in advance of the

                                                                              18





                 (o)  There shall not have occurred any invalidation of Rule
         144A under the Securities Act by any court or any withdrawal or
         proposed withdrawal of any rule or regulation under the Securities Act
         or the Exchange Act by the Commission or any amendment or proposed
         amendment thereof by the Commission which in the judgment of the
         Initial Purchaser would materially impair the ability of the Initial
         Purchaser to purchase, hold or effect resales of the Securities as
         contemplated hereby.

                 (p)  Subsequent to the execution and delivery of this
         Agreement or, if earlier, the dates as of which information is given
         in the Offering Memorandum (exclusive of any amendment or supplement
         thereto), there shall not have been any change in the capital stock or
         long-term debt or any change, or any development involving a
         prospective change, in or affecting the condition (financial or
         otherwise), results of operations, business or prospects of the
         Company taken as a whole, the effect of which, in any such case
         described above, is, in the judgment of the Initial Purchaser, so
         material and adverse as to make it impracticable or inadvisable to
         proceed with the sale or delivery of the Securities on the terms and
         in the manner contemplated by this Agreement and the Offering
         Memorandum (exclusive of any amendment or supplement thereto).

                 (q)  No action shall have been taken and no statute, rule,
         regulation or order shall have been enacted, adopted or issued by any
         governmental agency or body which would, as of the Closing Date,
         prevent the issuance or sale of the Securities; and no injunction,
         restraining order or order of any other nature by any federal or state
         court of competent jurisdiction shall have been issued as of the
         Closing Date which would prevent the issuance or sale of the
         Securities.

                 (r)  Subsequent to the execution and delivery of this
         Agreement (i) no downgrading shall have occurred in the rating
         accorded the Securities or any of the Company's other debt securities
         or preferred stock by any "nationally recognized statistical rating
         organization", as such term is defined by the Commission for purposes
         of Rule 436(g)(2) of the rules and regulations of the Commission under
         the Securities Act and (ii) no such organization shall have publicly
         announced that it has under surveillance or review (other than an
         announcement with positive implications of a possible upgrading), its
         rating of the Securities or any of the Company's other debt securities
         or preferred stock.

                 (s)  Subsequent to the execution and delivery of this
         Agreement there shall not have occurred any of the following: (i)
         trading in securities generally on the New York Stock Exchange, the
         American Stock Exchange, the Chicago Board Options Exchange or the
         over-the-counter market shall have been suspended or limited, or
         minimum prices shall have been established on any such exchange or
         market by the Commission, by any such exchange or by any other
         regulatory body or governmental authority having jurisdiction, or
         trading in any securities of the Company on any exchange or in the
         over-the-counter market shall have been suspended or (ii) any
         moratorium on commercial banking activities shall have been declared
         by federal or New York state authorities or (iii) an outbreak or
         escalation of hostilities or a declaration by the United States of a
         national emergency or war or (iv) a material adverse change in general
         economic, political or financial conditions (or the effect of
         international conditions on the financial markets in the United States
         shall be such) the effect of which, in the case of this clause (iv),
         is, in the judgment of the Initial Purchaser, so material and adverse
         as to make it impracticable or inadvisable to
<PAGE>   19
                                                                              19

         proceed with the sale or the delivery of the Securities on the terms
         and in the manner contemplated by this Agreement and in the Offering
         Memorandum (exclusive of any amendment or supplement thereto).

                 (t)  A valid and perfected first priority security interest in
         the Escrow Collateral shall have been created in favor of the Trustee
         for the benefit of Holders.

                 All opinions, letters, evidence and certificates mentioned
         above or elsewhere in this Agreement shall be deemed to be in
         compliance with the provisions hereof only if they are in form and
         substance reasonably satisfactory to counsel for the Initial
         Purchaser.

                 6.  Termination.  The obligations of the Initial Purchaser
hereunder may be terminated by the Initial Purchaser, in its absolute
discretion, by notice given to and received by the Company prior to delivery of
and payment for the Securities if, prior to that time, any of the events
described in Section 5(n), (o), (p), (q) or (r) shall have occurred and be
continuing.

                 7.  Reimbursement of Initial Purchaser's Expenses.  If (a)
this Agreement shall have been terminated pursuant to Section 6, (b) the
Company shall fail to tender the Securities for delivery to the Initial
Purchaser for any reason permitted under this Agreement or (c) the Initial
Purchaser shall decline to purchase the Securities for any reason permitted
under this Agreement, the Company shall reimburse the Initial Purchaser for
such out-of-pocket expenses (including reasonable fees and disbursements of
counsel) as shall have been reasonably incurred by the Initial Purchaser in
connection with this Agreement and the proposed purchase and resale of the
Securities.

                 8.  Indemnification.  (a)  The Company shall hold harmless the
Initial Purchaser, its affiliates, their respective officers, directors,
employees, representatives and agents, and each person, if any, who controls
any Initial Purchaser within the meaning of the Securities Act or the Exchange
Act (collectively referred to for purposes of this Section 8(a) and Section 9
as the Initial Purchaser), from and against any loss, claim, damage or
liability, joint or several, or any action in respect thereof (including,
without limitation, any loss, claim, damage, liability or action relating to
purchases and sales of the Securities), to which the Initial Purchaser may
become subject, whether commenced or threatened, under the Securities Act, the
Exchange Act, any other federal or state statutory law or regulation, at common
law or otherwise, insofar as such loss, claim, damage, liability or action
arises out of, or is based upon, (i) any untrue statement or alleged untrue
statement of a material fact contained in the Preliminary Offering Memorandum
or the Offering Memorandum or in any amendment or supplement thereto or in any
information provided by the Company pursuant to Section 4(e) or (ii) the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading, and
shall reimburse each Initial Purchaser promptly upon demand for any legal or
other expenses reasonably incurred by that Initial Purchaser in connection with
investigating or defending or preparing to defend against or appearing as a
third party witness in connection with any such loss, claim, damage, liability
or action as such expenses are incurred; provided, however, that the Company
shall not be liable in any such case to the extent that any such loss, claim,
damage, liability or action arises out of, or is based upon, an untrue
statement or alleged untrue statement in or omission or alleged omission from
any of such documents in reliance upon and in
<PAGE>   20
                                                                              20

conformity with any Initial Purchaser's Information; and provided, further,
that with respect to any such untrue statement in or omission from the
Preliminary Offering Memorandum, the indemnity agreement contained in this
Section 8(a) shall not inure to the benefit of any such Initial Purchaser to
the extent that the sale to the person asserting any such loss, claim, damage,
liability or action was an initial resale by the Initial Purchaser and any such
loss, claim, damage, liability or action of or with respect to the Initial
Purchaser results from the fact that both (A) to the extent required by
applicable law, a copy of the Offering Memorandum was not sent or given to such
person at or prior to the written confirmation of the sale of such Securities
to such person and (B) the untrue statement in or omission from the Preliminary
Offering Memorandum was corrected in the Offering Memorandum unless, in either
case, such failure to deliver the Offering Memorandum was a result of
non-compliance by the Company with Section 4(b).

                 (b)  The Initial Purchaser shall indemnify and hold harmless
the Company, its affiliates, their respective officers, directors, employees,
representatives and agents, and each person, if any, who controls the Company
within the meaning of the Securities Act or the Exchange Act (collectively
referred to for purposes of this Section 8(b) and Section 9 as the Company),
from and against any loss, claim, damage or liability, joint or several, or any
action in respect thereof, to which the Company may become subject, whether
commenced or threatened, under the Securities Act, the Exchange Act, any other
federal or state statutory law or regulation, at common law or otherwise,
insofar as such loss, claim, damage, liability or action arises out of, or is
based upon, (i) any untrue statement or alleged untrue statement of a material
fact contained in the Preliminary Offering Memorandum or the Offering
Memorandum or in any amendment or supplement thereto or (ii) the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading, but in each case only
to the extent that the untrue statement or alleged untrue statement or omission
or alleged omission was made in reliance upon and in conformity with any
Initial Purchaser's Information, and shall reimburse the Company for any legal
or other expenses reasonably incurred by the Company in connection with
investigating or defending or preparing to defend against or appearing as a
third party witness in connection with any such loss, claim, damage, liability
or action as such expenses are incurred.

                 (c)  Promptly after receipt by an indemnified party under this
Section 8 of notice of any claim or the commencement of any action, the
indemnified party shall, if a claim in respect thereof is to be made against
the indemnifying party pursuant to Section 8(a) or 8(b), notify the
indemnifying party in writing of the claim or the commencement of that action;
provided, however, that the failure to notify the indemnifying party shall not
relieve it from any liability which it may have under this Section 8 except to
the extent that it has been materially prejudiced (through the forfeiture of
substantive rights or defenses) by such failure; and, provided, further, that
the failure to notify the indemnifying party shall not relieve it from any
liability which it may have to an indemnified party otherwise than under this
Section 8.  If any such claim or action shall be brought against an indemnified
party, and it shall notify the indemnifying party thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it
wishes, jointly with any other similarly notified indemnifying party, to assume
the defense thereof with counsel reasonably satisfactory to the indemnified
party.  After notice from the indemnifying party to the indemnified party of
its election to assume the defense of such claim or action, the indemnifying
party shall not be liable to the indemnified party under this Section 8 for any
legal or other expenses subsequently incurred by the indemnified party in
connection with the defense thereof other than reasonable costs of
investigation; provided, however, that an indemnified party shall
<PAGE>   21
                                                                              21

have the right to employ its own counsel in any such action, but the fees,
expenses and other charges of such counsel for the indemnified party will be at
the expense of such indemnified party unless (1) the employment of counsel by
the indemnified party has been authorized in writing by the indemnifying party,
(2) the indemnified party has reasonably concluded (based upon advice of
counsel to the indemnified party) that there may be legal defenses available to
it or other indemnified parties that are different from or in addition to those
available to the indemnifying party, (3) a conflict or potential conflict
exists (based upon advice of counsel to the indemnified party) between the
indemnified party and the indemnifying party (in which case the indemnifying
party will not have the right to direct the defense of such action on behalf of
the indemnified party) or (4) the indemnifying party has not in fact employed
counsel reasonably satisfactory to the indemnified party to assume the defense
of such action within a reasonable time after receiving notice of the
commencement of the action, in each of which cases the reasonable fees,
disbursements and other charges of counsel will be at the expense of the
indemnifying party or parties.  It is understood that the indemnifying party or
parties shall not, in connection with any proceeding or related proceedings in
the same jurisdiction, be liable for the reasonable fees, disbursements and
other charges of more than one separate firm of attorneys (in addition to any
local counsel) at any one time for all such indemnified party or parties.  Each
indemnified party, as a condition of the indemnity agreements contained in
Sections 8(a) and 8(b), shall use all reasonable efforts to cooperate with the
indemnifying party in the defense of any such action or claim.  No indemnifying
party shall be liable for any settlement of any such action effected without
its written consent (which consent shall not be unreasonably withheld), but if
settled with its written consent or if there be a final judgment for the
plaintiff in any such action, the indemnifying party agrees to indemnify and
hold harmless any indemnified party from and against any loss or liability by
reason of such settlement or judgment.  No indemnifying party shall, without
the prior written consent of the indemnified party (which consent shall not be
unreasonably withheld), effect any settlement of any pending or threatened
proceeding in respect of which any indemnified party is or could have been a
party and indemnity could have been sought hereunder by such indemnified party
unless such settlement includes an unconditional release of such indemnified
party from all liability on claims that are the subject matter of such
proceeding.

                 The obligations of the Company and the Initial Purchaser in
this Section 8 and in Section 9 are in addition to any other liability that the
Company or the Initial Purchaser, as the case may be, may otherwise have,
including in respect of any breaches of representations, warranties and
agreements made herein by any such party.

                 9.  Contribution.  If the indemnification provided for in
Section 8 is unavailable or insufficient to hold harmless an indemnified party
under Section 8(a) or 8(b), then each indemnifying party shall, in lieu of
indemnifying such indemnified party, contribute to the amount paid or payable
by such indemnified party as a result of such loss, claim, damage or liability,
or action in respect thereof, (i) in such proportion as shall be appropriate to
reflect the relative benefits received by the Company on the one hand and the
Initial Purchaser on the other from the offering of the Securities or (ii) if
the allocation provided by clause (i) above is not permitted by applicable law,
in such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Company on
the one hand and the Initial Purchaser on the other with respect to the
statements or omissions that resulted in such loss, claim, damage or liability,
or action in respect thereof, as well as any other relevant equitable
considerations.  The relative benefits received by the Company on the one hand
and the Initial Purchaser on the other with respect to such offering shall be
deemed to be in the same proportion as the total
<PAGE>   22
                                                                              22

net proceeds from the offering of the Securities purchased under this Agreement
(before deducting expenses) received by or on behalf of the Company, on the one
hand, and the total discounts and commissions received by the Initial Purchaser
with respect to the Securities purchased under this Agreement, on the other,
bear to the total gross proceeds from the sale of the Securities under this
Agreement, in each case as set forth in the table on the cover page of the
Offering Memorandum.  The relative fault 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 the Company or information supplied by the Company on the one hand
or to any Initial Purchaser's Information on the other, the intent of the
parties and their relative knowledge, access to information and opportunity to
correct or prevent such untrue statement or omission.  The Company  and the
Initial Purchaser agree that it would not be just and equitable if
contributions pursuant to this Section 9 were to be determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to herein.  The amount paid or payable by
an indemnified party as a result of the loss, claim, damage or liability, or
action in respect thereof, referred to above in this Section 9 shall be deemed
to include, for purposes of this Section 9, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending or preparing to defend any such action or claim.  Notwithstanding
the provisions of this Section 9, the Initial Purchaser shall not be required
to contribute any amount in excess of the amount by which the total discounts
and commissions received by the Initial Purchaser with respect to the
Securities purchased by it under this Agreement exceeds the amount of any
damages which such Initial Purchaser has otherwise paid or become liable to pay
by reason of any 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 be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.

                 10.  Persons Entitled to Benefit of Agreement.  This Agreement
shall inure to the benefit of and be binding upon the Initial Purchaser and the
Company and their respective successors.  This Agreement and the terms and
provisions hereof are for the sole benefit of only those persons, except as
provided in Sections 8 and 9 with respect to affiliates, officers, directors,
employees, representatives, agents and controlling persons of the Company and
the Initial Purchaser and in Section 4(e) with respect to holders and
prospective purchasers of the Securities.  Nothing in this Agreement is
intended or shall be construed to give any person, other than the persons
referred to in this Section 10, any legal or equitable right, remedy or claim
under or in respect of this Agreement or any provision contained herein.

                 11.  Expenses.  The Company agrees with the Initial Purchaser
to pay (a) the costs incident to the authorization, issuance, sale, preparation
and delivery of the Securities and any taxes payable in that connection; (b)
the costs incident to the preparation, printing and distribution of the
Preliminary Offering Memorandum, the Offering Memorandum and any amendments or
supplements thereto; (c) the costs of reproducing and distributing each of the
Transaction Documents; (d) the costs incident to the preparation, printing and
delivery of the certificates evidencing the Securities, including stamp duties
and transfer taxes, if any, payable upon issuance of the Securities; (e) the
fees and expenses of the Company's counsel and independent accountants; (f) the
fees and expenses of qualifying the Securities under the securities laws of the
several jurisdictions as provided in Section 4(g) and of preparing, printing
and distributing Blue Sky Memoranda (including related fees and expenses of
counsel for the Initial Purchaser); (g) the fees and expenses of the Trustee
and any paying agent (including related fees and expenses of any counsel to
such parties); (h) all expenses
<PAGE>   23
                                                                              23

and application fees incurred in connection with the application for the
inclusion of the Securities on the PORTAL Market and the approval of the
Securities for book-entry transfer by DTC; and (i) all other costs and expenses
incident to the performance of the obligations of the Company under this
Agreement which are not otherwise specifically provided for in this Section 11;
provided, however, that except as provided in this Section 11 and Section 7,
the Initial Purchaser shall pay its own costs and expenses.

                 12.  Survival.  The respective indemnities, rights of
contribution, representations, warranties and agreements of the Company and the
Initial Purchaser contained in this Agreement or made by or on behalf of the
Company or the Initial Purchaser pursuant to this Agreement or any certificate
delivered pursuant hereto shall survive the delivery of and payment for the
Securities and shall remain in full force and effect, regardless of any
termination or cancelation of this Agreement or any investigation made by or on
behalf of any of them or any of their respective affiliates, officers,
directors, employees, representatives, agents or controlling persons.  The
Company agrees to cause each subsidiary that becomes a Subsidiary Guarantor
under the Indenture to become jointly and severally liable for all of the
Company's obligations under this agreement.

                 13.  Notices, etc..  All statements, requests, notices and

or investigative (other than an action by or in the right of the Corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding 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.

         Section 2. The Corporation shall indemnify any person 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 a 


                                      -6-
<PAGE>   7

director, officer, employee or agent of the Corporation, or is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection with the defense or settlement of such action or suit 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 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 Delaware Court of Chancery or the court
in which such action or suit was brought shall determine upon application that,
despite the adjudication of liability but in view of all the circumstances of
the case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Delaware Court of Chancery or such other court shall deem
proper.

         Section 3. To the extent that a director, officer, employee or agent of
the Corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in Sections 1 and 2, or in defense of any
claim, issue or matter therein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.

         Section 4. Any indemnification under Sections 1 and 2 (unless ordered
by a court) shall be made by the Corporation only as authorized in the specific
case upon a determination that indemnification of the director, officer,
employee or agent is proper in the circumstances because he has met the
applicable standard of conduct set forth in Sections 1 and 2. Such determination
shall be made (i) by the Board of Directors by a majority vote of a quorum
consisting of directors who were not parties to such action, suit or proceeding,
or (ii) if such a quorum is not obtainable, or, even 

                                       7
<PAGE>   8

if obtainable, if a quorum of disinterested directors so directs, by independent
legal counsel in a written opinion, or (iii) by the stockholders.
Notwithstanding the foregoing, a director, officer, employee or agent of the
Corporation shall be able to contest any determination that the director,
officer, employee or agent has not met the applicable standard of conduct set
forth in Sections 1 and 2 by petitioning a court of appropriate jurisdiction.

         Section 5. Expenses (including attorneys' fees) incurred by an officer
or director in defending or settling any civil, criminal, administrative or
investigative action, suit or proceeding shall be paid by the Corporation in
advance of the final disposition of such action, suit or proceeding upon receipt
of an undertaking by or on behalf of such director or officer to repay such
amount if it shall ultimately be determined that he is not entitled to be
indemnified by the Corporation as authorized in this Article IX. Such expenses
incurred by other employees and agents may be so paid upon such terms and
conditions, if any, as the Board of Directors deems appropriate.

         Section 6. The indemnification and advancement of expenses provided by,
or granted pursuant to, the other sections of this Article IX shall not be
deemed exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under any Bylaw, agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in his
official capacity and as to action in another capacity while holding such
office.

         Section 7. The Corporation shall have the power to purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise against any liability
asserted against him and incurred by him in any such capacity, or arising out of
his status as such, whether or not the 

                                      -8-
<PAGE>   9

Corporation would have the power to indemnify him against such liability under
the provisions of this Article IX.

         Section 8. For purposes of this Article IX, references to "the
Corporation" shall include, in addition to the Corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers, and employees
or agents, so that any person who is or was a director, officer, employee or
agent of such constituent corporation, or is or was serving at the request of
such constituent corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
shall stand in the same position under the provisions of this Article IX with
respect to the Corporation as he would have with respect to such constituent
corporation if its separate existence had continued.

         Section 9. For purposes of this Article IX, references to "other
enterprises" shall include employee benefit plans; references to "fines" shall
include any excise taxes assessed on a person with respect to an employee
benefit plan; and references to "serving at the request of the Corporation"
shall include any service as a director, officer, employee or agent of the
Corporation which imposes duties on, or involves services by, such director,
officer, employee or agent with respect to an employee benefit plan, its
participants or beneficiaries; and a person who acted in good faith and in a
manner he reasonably believed to be in the interest of the participants and
beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner "not opposed to the best interests of the Corporation" as referred to in
this Article IX.

         Section 10. The indemnification and advancement of expenses provided
by, or granted pursuant to, this Article IX shall, unless otherwise provided
when authorized or ratified, continue 

                                      -9-
<PAGE>   10

as to a person who has ceased to be a
director, officer, employee or agent and shall inure to the benefit of the
heirs, executors and administrators of such a person.

         Section 11. The Corporation shall indemnify its directors, officers and
agents to the fullest extent permitted herein, by the Bylaws of the Corporation,
and by the Delaware General Corporation Law.

         Section 2.      Registered office. The registered office of the

         Section 3.      Other Offices. The Corporation may also have offices at
such other places, both within and without the State of Texas or the State of
Delaware, as the Board of Directors may from time to time determine or the
business of the Corporation may require.


                                   ARTICLE II.

                            MEETINGS OF STOCKHOLDERS

         Section 1.      Place of Meetings. Meetings of stockholders for all 
purposes may be held at such time and place, within or without the State of
Texas, as shall be stated in the notice of the meeting or in a duly executed
waiver of notice thereof.

         Section 2.      Annual Meeting. The annual meeting of the stockholders
shall be held on the third Tuesday of April of each year. If this day falls on a
legal holiday, the annual meeting shall be held at the same time on the next
following business day thereafter, or on such other day as the Board of
Directors shall agree. At such meetings, the stockholders shall elect a Board of
Directors and transact such other business as may properly be brought before the
meeting.

         Section 3.      List of Stockholders. At least ten (10) days before 
each meeting of the stockholders, a complete list of the stockholders entitled
to vote at said meeting or any adjournment thereof, arranged in alphabetical
order with the address of and the number of voting shares held by each, shall be
prepared by the officer or agent having charge of the stock transfer books. Such
list, for a period of ten (10) days prior to such meeting, shall be kept on file
at the registered office or principal place of business of the Corporation and
shall be subject to inspection by any stockholder at any time during usual
business hours. Such list shall be produced and kept open at the time and place
of the meeting during the whole time thereof, and shall be subject to the
inspection of any stockholder who may be present.

         Section 4.      Special Meetings. Special meetings of the stockholders,
for any purpose or purposes, unless otherwise prescribed by statute, the
Certificate of Incorporation, or these Bylaws, 


<PAGE>   4


may be called by (a) the President or the Board of Directors, or (b) the holders
of at least ten percent (10%) of all shares entitled to vote at such meetings,
unless the Certificate of Incorporation provides for a number of shares greater
than or less than ten percent (10%), in which event special meetings may be
called by the holders of at least the percentage of shares specified in the
Certificate of Incorporation, provided, however, that in no event may the
Certificate of Incorporation require a percentage greater than fifty percent
(50%). Business transacted at a special meeting shall be confined to the
purposes stated in the notice of the meeting.

         Section 5.      Notice. Written or printed notice stating the place, 
day and hour of a meeting of stockholders, and, in case of a special meeting,
the purpose or purposes for which the meeting is called, shall be delivered not
less than ten (10) or, in the event of a merger or consolidation, not less than
twenty (20), nor more than sixty (60) days before the date of the meeting,
either personally or by mail or other means of written communication, by or at
the direction of the President, the Secretary, or the officer or person calling
the meeting, to each stockholder of record entitled to vote at the meeting.
Notice need not be given to a stockholder if (1) notice of two consecutive
annual meetings and all notices of any meetings held during the period between
those annual meetings or (2) all (but in no event less than two) payments (if
sent by first class mail) of distributions or interest on securities during a
12-month period have been mailed to the stockholder, addressed at his address as
shown on the records of the Corporation, and have been returned undeliverable.
If such a stockholder delivers to the Corporation a written notice setting forth
his current address, the notice requirement of this Section shall be reinstated.

         Section 6.      Quorum. At each meeting the holders of a majority of 
the shares issued and outstanding and entitled to vote thereat, present in
person or represented by proxy, shall be requisite and shall constitute a quorum
of the stockholders for the transaction of business except as otherwise provided
by statute, the Certificate of Incorporation or these Bylaws, but in no event
shall a quorum consist of the holders of less than one-third of the shares
entitled to vote at such a meeting. If, however, such quorum shall not be
present or represented at any meeting of the stockholders, the stockholders
entitled to vote thereat, present in person or represented by proxy, shall have
power to adjourn the meeting, until a quorum shall be present or represented. At
such adjourned meeting at which a quorum shall be present or represented, any
business may be transacted which might have been transacted at the meeting as
originally notified.

         Section 7.      Voting by Stockholders. (a) With respect to any matter
other than the election of directors or a matter for which the affirmative vote
of the holders of a specified portion of the shares entitled to vote is required
by the Delaware General Corporation Law, the affirmative vote of the holders of
a majority of the shares entitled to vote on that matter and represented in
person or by proxy at a meeting of stockholders at which a quorum is present
shall be the act of the stockholders, unless otherwise provided in the
Certificate of Incorporation or the Bylaws.

         (b)   Unless otherwise provided in the Certificate of Incorporation or
the Bylaws, directors shall be elected by a plurality of the votes cast by the
holders of shares entitled to vote in the election of directors at a meeting of
stockholders at which a quorum is present.

                                      -2-
<PAGE>   5

         Section 8.      Voting Procedure. Each outstanding share, regardless of
class, shall be entitled to one vote on each matter submitted to a vote at a
meeting of stockholders, except to the extent that the voting rights of the
shares of any class or classes are limited or denied or special voting rights
are provided by the Certificate of Incorporation. At any meeting of the
stockholders, every stockholder having the right to vote shall be entitled to
vote in person, by proxy appointed by an instrument in writing subscribed by
such stockholder, or by his duly authorized attorney-in-fact. No form of proxy
or power of attorney bearing a date more than eleven (11) months prior to said
meeting shall be valid, unless said instrument provides for a longer period.
Each proxy shall be revocable unless the proxy form conspicuously states that
the proxy is irrevocable and the proxy is coupled with an interest. Such proxy
shall be filed with the Secretary of the Corporation prior to or at the time of
the meeting.

         Section 9.      Record Date. (a) For the purpose of determining 
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, or entitled to receive a distribution by the
Corporation (other than a distribution involving a purchase or redemption by the
Corporation of any of its own shares) or a share dividend, or in order to make a
determination of stockholders for any other proper purpose (other than
determining stockholders entitled to consent to action by stockholders proposed
to be taken without a meeting of stockholders), the Board of Directors of the
Corporation may provide that the share transfer records shall be closed for a
stated period but not to exceed, in any case, sixty (60) days. If the share
transfer records shall be closed for the purpose of determining stockholders
entitled to notice of or to vote at a meeting of stockholders, such records
shall be closed for at least ten (10) days immediately preceding such meeting.
In lieu of closing the share transfer records, the Bylaws or, in the absence of
an applicable Bylaw, the Board of Directors, may fix in advance a date as the
record date for any such determination of stockholders, such date in any case to
be not more than sixty (60) days and, in the case of a meeting of stockholders,
not less than ten (10) days, prior to the date on which the particular action
requiring such determination of stockholders is to be taken. If the share
transfer records are not closed and no record date is fixed for the
determination of stockholders entitled to notice of or to vote at a meeting of
stockholders, or stockholders entitled to receive a distribution (other than a
distribution involving a purchase or redemption by the Corporation of any of its
own shares) or a share dividend, the date on which notice of the meeting is
mailed or the date on which the resolution of the Board of Directors declaring
such distribution or share dividend is adopted, as the case may be, shall be the
record date for such determination of stockholders. When a determination of
stockholders entitled to vote at any meeting of stockholders has been made as
provided in this subsection, such determination shall apply to any adjournment
thereof, except where the determination has been made through the closing of the
share transfer records and the stated period of closing has expired.

         (b)   For the purpose of determining stockholders entitled to call a
special meeting of stockholders pursuant to Section 4 of this Article II, the
record date shall be the date the first stockholder signs the notice of the
meeting.

         (c)   Unless a record date shall have previously been fixed or 
determined pursuant to this section, whenever action by stockholders is proposed
to be taken by consent in writing without a

                                      -3-

<PAGE>   6

meeting of stockholders, the Board of Directors may fix a record date for the
purpose of determining stockholders entitled to consent to that action, which
record date shall not precede, and shall not be more than ten (10) days after,
the date upon which the resolution fixing the record date is adopted by the
Board of Directors. If no record date has been fixed by the Board of Directors
and the prior action of the Board of Directors is not required by the Delaware
General Corporation Law, the record date for determining stockholders entitled
to consent to action in writing without a meeting shall be the first date on
which a signed written consent setting forth the action taken or proposed to be
taken is delivered to the Corporation in the manner provided by Section 10(b) of
this Article II. If no record date shall have been fixed by the Board of
Directors and prior action of the Board of Directors is required by the Delaware
General Corporation Law, the record date for determining stockholders entitled
to consent to action in writing without a meeting shall be at the close of
business on the date on which the Board of Directors adopts a resolution taking
such prior action.

         (e)   Subject to applicable notice provisions and unless otherwise
restricted by the Certificate of Incorporation, stockholders may participate in
and hold a meeting 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 in such meeting shall constitute presence in
person at such meeting, except where a person's participation is for the express
purpose of objecting to the transaction of any business on the ground that the
meeting is not lawfully called or convened.


                                  ARTICLE III.

                                   DIRECTORS


         Section 1.      Management. The business and affairs of the Corporation
shall be managed by its Board of Directors who may exercise all such powers of
the Corporation and do all such lawful acts and things as are not by statute or
by the Certificate of Incorporation or by these Bylaws directed or required to
be exercised or done by the stockholders. The Board of Directors shall keep
regular minutes of its proceedings.

         Section 2.      Number, Qualifications and Term. The Board of Directors
shall consist of at least two (2) members but no more than seven (7) members
unless otherwise determined from time to time by resolution adopted by the
stockholders or by the Board of Directors. No decrease in the number of
directors shall shorten the term of any incumbent director. Directors need not
be stockholders of the Corporation or residents of Texas or Delaware. Effective
as of the 1998 annual meeting of stockholders, except as otherwise provided in
Article III, Section 4 of these Bylaws, the Board of Directors shall be divided
into three classes, each class to be as nearly equal in number as possible. The
terms of office of directors of the first class are to expire at the first
annual meeting of stockholders after their first election or appointment, that
of the second class is to expire at the second annual meeting of stockholders
after their first election or appointment, and that of the third class is to
expire at the third annual meeting of stockholders after their first election or
appointment. Thereafter, each director shall serve for a term ending on the date
of the third annual meeting of stockholders following the annual meeting at
which such director was elected. Each person elected a director shall hold
office until his successor is duly elected and qualified or until his earlier
resignation or removal.

         Section 3.      Change in Number. The number of Directors and the class
thereof may be increased or decreased from time to time by resolution adopted by
the affirmative vote of a majority of the Directors, but no decrease shall have
the effect of shortening the term of any incumbent Director.

         Section 4.      Removal and Vacancies. Any Director may be removed 
either for or without cause at any annual or special meeting of stockholders by
the affirmative vote of a majority in number of shares of the stockholders
present in person or by proxy at such meeting and entitled to vote for the
election of such Director, if notice of the intention to act upon such matters
shall have 

                                      -5-
<PAGE>   8

been given in the notice calling such meeting. Any vacancy occurring
in the Board of Directors may be filled by the vote of a majority of the
remaining Directors, even if such remaining Directors comprise less than a
quorum of the Board of Directors. A Director elected to fill a vacancy shall be
elected for the unexpired term of his predecessor in office. Any position on the
Board of Directors to be filled by reason of an increase in a number of
Directors shall be filled by the vote of a majority of Directors, election at an
annual meeting of the stockholders or at a special meeting of stockholders duly
called for such purpose.

         Section 5.      Election of Directors. At every election of Directors,
each stockholder entitled to vote with respect to such matter shall have the
right to vote in person or by proxy the number of voting shares owned by him for
as many persons as there are Directors to be elected and for whose election he
has a right to vote. Cumulative voting shall be prohibited.

         Section 6.      Place of Meetings.  The Directors of the Corporation 
may hold their meetings, both regular and special, either within or without the
State of Texas.

         Section 7.      First Meetings. The first meeting of each newly elected
Board of Directors shall be held without further notice immediately following
the annual meeting of stockholders, and at the same place, unless by unanimous
consent of the Directors then elected and serving, such time or place shall be
changed.



         Section 8.      Regular Meetings.  Regular meetings of the Board of 
Directors may be held without notice at such time and place as shall from time
to time be determined by the Board of Directors.

         Section 9.      Special Meetings. Special meetings of the Board of
Directors may be called by the President on three (3) days' notice to each
Director, either personally, by mail, by telegram, or by facsimile. Special
meetings may be called in like manner and on like notice on the written request
of any two Directors. Except as may be otherwise expressly provided by statute,
the Certificate of Incorporation or these Bylaws, neither the business to be
transacted at, nor the purpose of, any special meeting need be specified in a
notice or waiver of notice.

         Section 10.     Quorum. At all meetings of the Board of Directors, the
presence of a majority of the Directors shall be necessary and sufficient to
constitute a quorum for the transaction of business, and the act of a majority
of the Directors present at any meeting at which there is a quorum shall be the
act of the Board of Directors, except as may be otherwise specifically provided
by statute, the Certificate of Incorporation or these Bylaws. If a quorum shall
not be present at any meeting of Directors, the Directors present thereat may
adjourn the meeting from time to time, without notice other than announcement at
the meeting, until a quorum shall be present.

         Section 11.     Action Without Meeting; Telephone Meetings. Any action
required or permitted to be taken at a meeting of the Board of Directors or
members of any committee designated by the Board of Directors may be taken
without a meeting if a consent in writing, setting forth the action so taken, is
signed by all the members of the Board of Directors or committee, as the 

                                      -6-

<PAGE>   9
case may be. Such consent shall have the same force and effect as a unanimous
vote at a meeting. Subject to applicable notice provisions and unless otherwise
restricted by the Certificate of Incorporation, members of the Board of
Directors, or members of any committee designated by the Board of Directors, may
participate in and hold a meeting 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 in such meeting shall constitute
presence in person at such meeting, except where a person's participation is for
the express purpose of objecting to the transaction of any business on the
ground that the meeting is not lawfully called or convened.

         Section 12.     Chairman of the Board. The Board of Directors may elect
a Chairman of the Board to preside at their meetings and to perform such other
duties as the Board of Directors may from time to time assign to him.

         Section 13.     Compensation. Directors, as such, shall not receive any
stated salary for their services, but by resolution of the Board of Directors a
fixed sum, stock options, and other compensation including but not limited to
employee benefits along with expenses of attendance, if any, may be allowed for
attendance at each regular or special meeting of the Board of Directors;
provided that nothing herein contained shall be construed to preclude any
Director from serving the Corporation in any other capacity and receiving
compensation therefor. Members of any committee designated by the Board of
Directors may, by resolution of the Board of Directors, be allowed compensation
for attending committee meetings.

         Section 14.     Committees. The Board of Directors may, by resolution
adopted by a majority of the whole Board of Directors, designate from among its
members one or more committees, other than an Executive Committee, to the extent
provided in such resolution.



                                   ARTICLE IV.

                                     NOTICES

         Section 1.      Method. Whenever by statute, the Certificate of
Incorporation, or these Bylaws, notice is required to be given to any Director
or stockholder, and no provision is made as to how such notice shall be given,
it shall not be construed to mean personal notice, but any such notice may be
given in writing, by mail, postage prepaid, addressed to such Director or
stockholder at such address as appears on the books of the Corporation or in any
other method permitted by law. Any notice required or permitted to be given by
mail shall be deemed to be given at the time when the same shall be thus
deposited in the United States mail as aforesaid.

         Section 2.      Waiver. Whenever any notice is required to be given to
any stockholder or Director of the Corporation by statute, the Certificate of
Incorporation, or these Bylaws, a waiver thereof in writing signed by the person
or persons entitled to such notice, whether before or after the time stated in
such notice, shall be deemed equivalent to the giving of such notice. Attendance
of 

                                      -7-

<PAGE>   10

a stockholder or Director at a meeting shall constitute a waiver of notice of
such meeting, except where a stockholder or Director attends for the express
purpose of objecting to the transaction of any business on the ground that the
meeting is not lawfully called or convened. Consent in writing by a stockholder
or Director to any action taken or resolution adopted by the stockholders or
Directors of the Corporation shall constitute a waiver of any and all notices
required to be given in connection with such action or resolution.



                                   ARTICLE V.

                                    OFFICERS

elected by the Directors and shall be a President and a Secretary. The Board of
Directors may also choose a Chairman of the Board, one or more Vice Presidents,

two or more offices may be held by the same person.

         Section 2.      Election. The Board of Directors at its first meeting
after each annual meeting of stockholders shall choose a President and a
Secretary, neither of whom need be a member of the Board of Directors, a
stockholder, or a resident of the State of Texas. The Board of Directors may
appoint such other officers and agents as it shall deem necessary, who shall be
appointed for such terms and shall exercise such powers and perform such duties
as shall be determined from time to time by the Board of Directors.

         Section 3.      Removal and Vacancies.  Each officer of the Corporation
shall hold office until his successor is chosen and qualified in his stead or
until his death or until his resignation or removal from office. Any officer or
agent or member of a committee elected or appointed by the Board of Directors
may be removed either for or without cause by a majority of the Board of
Directors present at a meeting of the Board of Directors at which a quorum is
represented, whenever in the judgment of the Board of Directors the best
interests of the Corporation will be served thereby, but such removal shall be
without prejudice to the contract rights, if any, of the person so removed. If
the office of any officer becomes vacant for any reason, the vacancy may be
filled by the Board of Directors.

         Section 4.      President. The President shall be the chief executive
officer of the Corporation. The President shall preside at all meetings of the
stockholders and the Board of Directors unless the Board of Directors shall
choose to elect a Chairman of the Board, in which event the President shall
preside at meetings of the Board of Directors in the absence of the Chairman of
the Board. The President shall have general and active management of the
business and affairs of the Corporation, shall see that all orders and
resolutions of the Board of Directors are carried into effect, and shall perform
such other duties as the Board of Directors shall prescribe.

time to time prescribe or as the President may from time to time delegate to
such Vice President.

         Section 6.      Secretary. The Secretary shall attend all sessions of 
the Board of Directors and all meetings of the stockholders and record all votes
and the minutes of all proceedings in a book to be kept for that purpose and
shall perform like duties for the Executive Committee when required. The
Secretary shall give, or cause to be given, notice of all meetings of the
stockholders and special meetings of the Board of Directors, and shall perform
such other duties as may be prescribed by the Board of Directors or President,
under whose supervision the Secretary shall be. The Secretary shall keep in safe

Directors, affix the same to any instrument requiring it, and, when so affixed,
it shall be attested by the Secretary's signature or by the signature of the
Treasurer or an Assistant Secretary.

         Section 7.      Assistant Secretaries. Each Assistant Secretary, if

accounts of receipts and disbursements of the Corporation and shall deposit all
monies and other valuable effects in the name and to the credit of the
Corporation in such depositories as may be designated by the Board of Directors.
The Treasurer shall disburse the funds of the Corporation as may be ordered by
the Board of Directors, taking proper vouchers for such disbursements, and shall
render to the President and Directors, at the regular meetings of the Board of
Directors, or whenever they may require it, an account of all transactions as
Treasurer and of the financial condition of the Corporation, and shall perform
such other duties as the Board of Directors may prescribe. If required by the

form, in such sum, and with surety or sureties as shall be satisfactory to the
Board of Directors for the faithful performance of the duties of such office and
for the restoration to the Corporation, in case of the Treasurer's death,
resignation, retirement or removal from office, of all books, papers, vouchers,
money, and other property of whatever kind in the Treasurer's possession or
under the Treasurer's control belonging to the Corporation.

         Section 9.      Assistant Treasurers.  Each Assistant Treasurer, if

         Section 1.      Certificates. Certificates in such form as may be 
determined by the Board of Directors shall be delivered representing all shares
to which stockholders are entitled. Such certificates shall be consecutively
numbered and shall be entered in the books of the Corporation as they are
issued. Each certificate shall state on the face thereof the holder's name, the
number and class of shares, and the par value of such shares or a statement that
such shares are without par value. They shall be signed by the President or a
Vice President and the Secretary or an Assistant Secretary and may be sealed
with the seal of the Corporation or a facsimile thereof. The signature of any
such officer may be facsimile.

         Section 2.      Lost Certificates. The Board of Directors may direct a
new certificate representing shares to be issued in place of any certificate
theretofore issued by the Corporation alleged to have been lost or destroyed,
upon the making of an affidavit of that fact by the person claiming the
certificate to be lost or destroyed. When authorizing such issue of a new
certificate, the Board of Directors, in its discretion and as a condition
precedent to the issuance thereof, may require the owner of such lost or
destroyed certificate, or the owner's legal representative, to advertise the
same in such manner as it shall require and/or give the Corporation a bond in
such form, in such sum, and with such surety or sureties as it may direct as
indemnity against any claim that may be made against the Corporation with
respect to the certificate alleged to have been lost or destroyed.

         Section 3.      Transfer of Shares. Shares of stock shall be
transferable only on the books of the Corporation by the holder thereof in
person or by the holder's duly authorized attorney. Upon surrender to the
Corporation or the transfer agent of the Corporation of a certificate
representing shares duly endorsed or accompanied by proper evidence of
succession, assignment or authority to transfer, it shall be the duty of the
Corporation or the transfer agent of the Corporation to issue a new certificate
to the person entitled thereto, cancel the old certificate and record the

liable for regarding that person as the owner of those shares at that time for
those purposes, regardless of whether that person does not possess a certificate
for those shares.

<PAGE>   13
                                  ARTICLE VII.

                               GENERAL PROVISIONS

         Section 1.      Distributions and Share Dividends. Distributions and
share dividends, subject to the provisions of the Certificate of Incorporation,
if any, may be authorized by the Board of Directors at any regular or special
meeting. Distributions may be paid in cash, in property, or in the issuance of
indebtedness, and may be in the form of a dividend on the outstanding shares of
the Corporation, a purchase or redemption by the Corporation of any of its own
shares, or a payment in liquidation of all or a portion of the assets of the
Corporation. Share dividends shall be paid in authorized but unissued shares of
the Corporation subject to the provisions of the Delaware General Corporation
Law and the Certificate of Incorporation. The Board of Directors may fix a
record date in the manner provided in Article II of these Bylaws for the purpose
of determining stockholders entitled to receive a distribution (other than a
distribution involving a purchase or redemption by the Corporation of any of its
own shares) or share dividend.

         Section 2.      Reserves. There may be created by resolution of the 
Board of Directors out of the surplus of the Corporation such reserve or
reserves as the Directors from time to time, in their discretion, think proper
to provide for contingencies, or to equalize distributions, or to repair or
maintain any property of the Corporation, or for such other purposes as the
Directors shall think beneficial to the Corporation, and the Directors may
modify or abolish any such reserve in the manner in which it was created.

         Section 3.      Checks.  All checks or demands for money and notes of 
the Corporation shall be signed by such officer or officers or such other person
or persons as the Board of Directors may from time to time designate.

         Section 4.      Fiscal Year.  The fiscal year of the Corporation shall
be fixed by resolution of the Board of Directors.

         Section 5.      Seal.  The corporate seal shall have inscribed thereon
the name of the Corporation. Said seal may be used by causing it or a facsimile
thereof to be impressed or affixed or reproduced or otherwise.

         Section 6.      Indemnification. The Corporation shall indemnify any 
person who was or is a 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 a director,
officer, employee or agent of the Corporation, or is or was serving at the
request of the Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding 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


                                      -11-

<PAGE>   14
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.

         The Corporation shall indemnify any person 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 a director, officer, employee or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit 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 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 Delaware Court
of Chancery or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Delaware Court of Chancery or
such other court shall deem proper.

         To the extent that a director, officer, employee or agent of the
Corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in the first and second paragraphs of
this Section, or in defense of any claim, issue or matter therein, he shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith.

         Any indemnification under the first and second paragraphs of this
Section (unless ordered by a court) shall be made by the Corporation only as
authorized in the specific case upon a determination that indemnification of the
director, officer, employee or agent is proper in the circumstances because he
has met the applicable standard of conduct set forth in the first and second
paragraphs of this Section. Such determination shall be made (i) by the Board of
Directors by a majority vote of a quorum consisting of directors who were not
parties to such action, suit or proceeding, or (ii) if such a quorum is not
obtainable, or, even if obtainable, if a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, or (iii) by the
stockholders. Notwithstanding the foregoing, a director, officer, employee or
agent of the Corporation shall be able to contest any determination that the
director, officer, employee or agent has not met the applicable standard of
conduct set forth in the first and second paragraphs of this Section, by
petitioning a court of appropriate jurisdiction.

         Expenses (including attorneys' fees) incurred by an officer or director
in defending or settling any civil, criminal, administrative or investigative
action, suit or proceeding shall be paid by the Corporation in advance of the
final disposition of such action, suit or proceeding upon receipt of an

                                      -12-
<PAGE>   15
undertaking by or on behalf of such director or officer to repay such amount if
it shall ultimately be determined that he is not entitled to be indemnified by
the Corporation as authorized in this Section. Such expenses incurred by other
employees and agents may be so paid upon such terms and conditions, if any, as
the Board of Directors deems appropriate.

         The indemnification and advancement of expenses provided by, or granted
pursuant to, the other paragraphs of this Section shall not be deemed exclusive
of any other rights to which those seeking indemnification or advancement of
expenses may be entitled under any agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in another capacity while holding such office.

         The Corporation shall have the power to purchase and maintain insurance
on behalf of any person who is or was a director, officer, employee or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against any liability asserted against him
and 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 him against
such liability under the provisions of this Section.

         For purposes of this Section, references to "the Corporation" shall
include, in addition to the Corporation, any constituent corporation (including
any constituent of a constituent) absorbed in a consolidation or merger which,
if its separate existence had continued, would have had power and authority to
indemnify its directors, officers, and employees or agents, so that any person
who is or was a director, officer, employee or agent of such constituent
corporation, or is or was serving at the request of such constituent corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, shall stand in the same position under
the provisions of this Section with respect to the Corporation as he would have
with respect to such constituent corporation if its separate existence had
continued.

         For purposes of this Section, references to "other enterprises" shall
include employee benefit plans; references to "fines" shall include any excise
taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the Corporation" shall include any
service as a director, officer, employee or agent of the Corporation which
imposes duties on, or involves services by, such director, officer, employee or
agent with respect to an employee benefit plan, its participants or
beneficiaries; and a person who acted in good faith and in a manner he
reasonably believed to be in the interest of the participants and beneficiaries
of an employee benefit plan shall be deemed to have acted in a manner "not
opposed to the best interests of the Corporation" as referred to in this
Section.

         The indemnification and advancement of expenses provided by, or granted
pursuant to, this Section shall, unless otherwise provided when authorized or
ratified, continue as to a person who has ceased to be a director, officer,

1.   Interest

          (a)  SPLITROCK SERVICES, INC., a Delaware corporation (such
corporation, and its successors and assigns under the Indenture hereinafter
referred to, being herein called the "Company"), promises to pay interest on
the principal amount of this Security at the rate per annum shown above. The
Company shall pay interest semiannually on January 15 and July 15 of each year,
commencing on [        ]. Interest on the Securities shall accrue from the most
recent date to which interest has been paid or, if no interest has been paid,
from [     ]. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

          (b)  Liquidated Damages. The holder of this Security is entitled to
the benefits of an Exchange and Registration Rights Agreement, dated as of July
24, 1998, between the Company and the Initial Purchaser named therein (the
"Registration Agreement"). Capitalized terms used in this paragraph (b) but not
defined herein have the meanings assigned to them in the Registration
Agreement. If (i) the Shelf Registration Statement or Exchange Offer
Registration Statement, as applicable under the Registration Agreement, is not
filed with the Commission on or prior to 45 days after the Issue Date, (ii) the
Exchange Offer Registration Statement or the Shelf Registration Statement, as
the case may be, is not declared effective within 105 days after the Issue Date
(or in the case of a Shelf Registration Statement required to be filed in
response to a change in law or the applicable interpretations of Commission's
staff, if later, within 45 days after publication of the change in law or
interpretation), (iii) the Registered Exchange Offer is not consummated on or
prior to 135 days after the Issue Date, or (iv) the Shelf Registration
Statement is filed and declared effective within 135 days after the Issue Date
(or in the case of a Shelf Registration Statement required to be filed in
response to a change in law or the applicable interpretations of Commission's
staff, if later, within 45 days after publication of the change in law or
interpretation) but shall thereafter cease to be effective (at any time that
the Company is obligated to maintain the effectiveness thereof) without being
succeeded within 30 days by an additional Registration Statement filed and
declared effective (each such event referred to in clauses (i) through (iv), a
"Registration Default"), the Company will be obligated to pay liquidated
damages to each Holder of Transfer Restricted Securities, during the period of
one or more such Registration Defaults, in an amount equal to $0.192 per week
per $1,000 principal amount of Transfer Restricted Securities held by such
Holder until (i) the applicable Registration Statement is filed, (ii) the
Exchange Offer Registration Statement is declared effective and the Registered
Exchange Offer is consummated, (iii) the Shelf Registration Statement is
declared effective or (iv) the Shelf Registration Statement again becomes
effective, as the case may be. All accrued liquidated damages shall be paid to
holders in the same manner as interest payments on the Securities on 
semi-annual payment dates which correspond to interest payment dates for the 
Securities. Following the cure of all Registration Defaults, the accrual of
liquidated damages shall cease. The Trustee shall have no responsibility with
respect to the determination of the amount of any such liquidated damages. For
purposes of the foregoing, "Transfer Restricted Securities" means (i) each
Initial Security until the date on which such Initial Security has been
exchanged for a freely transferable Exchange Security in the Registered
Exchange Offer, (ii) each Initial Security or Private Exchange Security until
the date on which such Initial Security or Private Exchange Security has been
effectively registered under the Securities Act and disposed of in

                                                                              2

accordance with a Shelf Registration Statement or (iii) each Initial Security
or Private Exchange Security until the date on which such Initial Security or
Private Exchange Security is distributed to the public pursuant to Rule 144
under the Securities Act or is saleable pursuant to Rule 144(k) under the
Securities Act.

2. Method of Payment

          The Company shall pay interest on the Securities (except defaulted
interest) to the Persons who are registered holders of Securities at the close
of business on the January 1 or July 1 next preceding the interest payment 
date even if Securities are canceled after the record date and on or before 
the interest payment date. Holder must surrender Securities to a Paying Agent
to collect principal payments. The Company shall pay principal and interest in
money of the United States of America that at the time of payment is legal
tender for payment of public and private debts. Payments in respect of the
Securities represented by a Global Security (including principal, premium and
interest) shall be made by wire transfer of immediately available funds to the
accounts specified by The Depository Trust Company. The Company shall make all
payments in respect of a certificated Security (including principal, premium,
and interest), by mailing a check to the registered address of each Holder
thereof; provided however, that payments on the Securities may also be made, in
the case of a Holder of at least $1,000,000 aggregate principal amount of
Securities, by wire transfer to a U.S. dollar account maintained by the payee
with a bank in the United States if such Holder elects payment by wire transfer
by giving written notice to the Trustee or the Paying agent to such effect
designating such account no later than 30 days immediately preceding the
relevant due date for payment (or such other date as the Trustee may accept in
its discretion).

3. Paying Agent and Registrar

          Initially, BANK OF MONTREAL TRUST COMPANY, a New York banking
corporation (the "Trustee"), shall act as Paying Agent and Registrar. The
Company may appoint and change any Paying Agent, Registrar or co-registrar
without notice. The company or a domestically incorporated Wholly Owned
Subsidiary of the Company, if any, may act as Paying Agent, Registrar or
co-registrar.

4. Indenture

          The Company issued the Securities under an Indenture dated as of
July 24, 1998 (the "Indenture"), between the Company and the Trustee. The terms
of the Securities include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
Sections 77aaa-77bbbb) as in effect on the date of the Indenture (the
"TIA"). Terms defined in the Indenture and not defined herein have the meanings
ascribed thereto in the Indenture. The Securities are subject to all terms and
provisions of the Indenture, and Securityholders are referred to the Indenture
and the TIA for a statement of such terms and provisions.

          The Securities are senior unsecured obligations of the Company
limited to $311,000,000 aggregate principal amount at any one time outstanding
(subject to Sections 2.01 and 2.08 of the Indenture). This Security is one of
the [Initial Securities] [Private Exchange Securities] referred to in the
Indenture issued in an aggregate principal amount of $261,000,000. The
Securities include the Initial Securities and any Exchange Securities and
Private Exchange Securities issued in exchange for the Initial Securities
pursuant to the Indenture. The Initial Securities, the Exchange Securities and
the Private

                                                                              3


Exchange Securities are treated as a single class of securities under the
Indenture. The Indenture imposes certain limitations on the ability of the
Company and its Restricted Subsidiaries to, among other things, make certain
Investments and other Restricted Payments, pay dividends and other
distributions, incur Indebtedness, enter into consensual restrictions upon the
payment of certain dividends and distributions by such Restricted Subsidiaries,
issue or sell shares of capital stock of such Restricted Subsidiaries, enter
into or permit certain transactions with Affiliates, create or incur Liens, make
asset sales and enter into Sale/Leaseback Transactions. The Indenture also
imposes limitations on the ability of the Company to consolidate or merge with
or into any other Person or convey, transfer or lease all or substantially all
of the property of the Company. In addition, the Indenture provides that each
Restricted Subsidiary of the Company that Incurs Indebtedness shall jointly and
severally Guarantee all of the Company's obligations under the Securities and
the Indenture.

5. OPTIONAL REDEMPTION

          Except as set forth in the following paragraph, the Securities shall
not be redeemable at the option of the Company prior to July 15, 2003. On or
after such date, the Securities shall be redeemable at the option of the
Company, in whole or in part, on not less than 30 nor more than 60 days prior
notice, at the following redemption prices (expressed as percentages of
principal amount), plus accrued and unpaid interest and liquidated damages (if
any) to the redemption date (subject to the right of holders of record on the
relevant record date to receive interest due on the relevant interest payment
date), if redeemed during the 12-month period commencing on July 15 of the years
set forth below:

                                                 Redemption
               Year                                 Price
               ----                                 -----

               2003                               105.875%
               2004                               103.917%
               2005                               101.958%
               2006 and thereafter                100.000%

          In addition, at any time and from time to time prior to July 15, 2001,
the Company may redeem up to a maximum of 35% of the original aggregate
principal amount of the Securities (calculated giving effect to any issuance of
Additional Securities) with the Net Cash Proceeds of one or more Equity
Offerings by the Company, at a redemption price equal to 111.75% of the
principal amount thereof, plus accrued and unpaid interest and liquidated
damages, if any, to date of redemption (subject to the right of holders of
record on the relevant record date to receive interest due on the relevant
interest payment date); provided, however, that at least 65% of the original
aggregate principal amount of the Securities remains outstanding immediately
after each such redemption (calculated giving effect to any issuance of
Additional Securities). Any such redemption shall be made within 60 days of
such Equity Offering upon not less than 30 nor more than 60 days notice mailed 
to each holder of Securities being redeemed and otherwise in accordance with 
the procedures set forth in the Indenture.

6. SINKING FUND

               The Securities are not subject to any sinking fund.
<PAGE>   8
                                                                               4



7.   Notice of Redemption

          Notice of redemption will be mailed by first-class mail at least 30
days but not more than 60 days before the redemption date to each Holder of
Securities to be redeemed at his or her registered address. Securities in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000. If money sufficient to pay the redemption price of and
accrued and unpaid interest on all Securities (or portions thereof) to be
redeemed on the redemption date is deposited with the Paying Agent on or before
the redemption date and certain other conditions are satisfied, on and after
such date interest ceases to accrue on such Securities (or such portions
thereof) called for redemption.

8.   Repurchase of Securities at the Option of Holders upon Change of Control

          Upon a Change of Control, any Holder of Securities will have the
right, subject to certain conditions specified in the Indenture, to cause the
Company to repurchase all or any part of the Securities of such Holder at a
purchase price equal to 101% of the principal amount of the Securities to be
repurchased plus accrued and unpaid interest, if any, to the date of repurchase
(subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date that is on or prior
to the date of purchase) as provided in, and subject to the terms of, the
Indenture.

9.   Denominations; Transfer; Exchange

          The Securities are in registered form without coupons in
denominations of $1,000 and whole multiples of $1,000. A Holder may transfer or
exchange Securities in accordance with the Indenture. Upon any transfer or
exchange, the Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements or transfer documents and to pay
any taxes required by law or permitted by the Indenture. The Registrar need not
register the transfer of or exchange any Securities selected for redemption
(except, in the case of a Security to be redeemed in part, the portion of the
Security not to be redeemed) or to transfer or exchange any Securities for a
period of 15 days prior to a selection of Securities to be redeemed.

10.  Persons Deemed Owners

          The registered Holder of this Security may be treated as the owner of
it for all purposes.

11.  Unclaimed Money

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its written request unless an abandoned property law designates
another Person. After any such payment, Holders entitled to the money must look
only to the Company and not to the Trustee for payment.

<PAGE>   9
                                                                               5
12.  Discharge and Defeasance

       Subject to certain conditions, the Company at any time may terminate some
of or all its obligations under the Securities and the Indenture if the Company
deposits with the Trustee money or U.S. Government Obligations for the payment
of principal and interest on the Securities to redemption or maturity, as the
case may be.

13.  Amendment Waiver  

       Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended without prior notice to any
Securityholder but with the written consent of the Holders of at least a
majority in aggregate principal amount of the outstanding Securities and (ii)
any default or noncompliance with any provision may be waived with the written
consent of the Holders of at least a majority in principal amount of the
outstanding Securities.  Subject to certain exceptions set forth in the
Indenture, without the consent of any Holder of Securities, the Company and the
Trustee may amend the Indenture or the Securities (i) to cure any ambiguity,
omission, defect or inconsistency; (ii) to comply with Article 5 of the
Indenture; (iii) to provide for uncertificated Securities in addition to or in
place of certificated Securities; (iv) to add Guarantees with respect to the
Securities; (v) to secure the Securities or to create and maintain a valid first
priority security interest in the Escrow Collateral in favor of the Trustee for
the benefit of Holders; (vi) to add additional covenants or to surrender rights
and powers conferred on the Company; (vii) to comply with the requirements of
the SEC in order to effect or maintain the qualification of the Indenture under
the TIA; (viii) to make any change that does not adversely affect the rights of
any Securityholder; or (ix) to provide for the issuance of the Exchange
Securities, Private Exchange Securities, or Additional Securities.

14.  Defaults and Remedies

       If an Event of Default occurs (other than an Event of Default relating to
certain events of bankruptcy, insolvency or reorganization of the Company) and
is continuing, the Trustee or the Holders of at least 25% in principal amount of
the outstanding Securities may declare the principal of and accrued but unpaid
interest on all the Securities to be due and payable.  If an Event of Default
relating to certain events of bankruptcy, insolvency or reorganization of the
Company occurs, the principal of and interest on all the Securities shall become
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holders.  Under certain circumstances, the Holders of a
majority in principal amount of the outstanding Securities may rescind any such
acceleration with respect to the Securities and its consequences.

       If an Event of Default occurs and is continuing, the Trustee shall be
under no obligation to exercise any of the rights or powers under the Indenture
at the request or direction of any of the Holders unless such Holders have
offered to the Trustee reasonable indemnity or security against any loss,
liability or expense.  Except to enforce the right to receive payment of
principal, premium (if any) or interest when due, no Holder may pursue any
remedy with respect to the Indenture or the Securities unless (i) such Holder
has previously given the Trustee notice that an Event of Default is continuing,
(ii) Holders of at least 25% in principal amount of the outstanding Securities
have requested the Trustee in writing to pursue the remedy, (iii) such Holders
have offered the Trustee reasonable security or indemnity against any loss,
liability or expense, (iv) the Trustee has not complied with such request within
60 days after the receipt of the request and the offer of security or


                                       
<PAGE>   10
                                                                              6


indemnity and (v) the Holders of a majority in principal amount of the
outstanding Securities have not given the Trustee a direction inconsistent with
such request within such 60-day period.  Subject to certain restrictions, the
Holders of a majority in principal amount of the outstanding Securities are
given the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or of exercising any trust
or power conferred on the Trustee.  The Trustee, however, may refuse to follow
any direction that conflicts with law, the Indenture or the Escrow and
Disbursement Agreement or that the Trustee determines is unduly prejudicial to
the rights of any other Holder or that would involve the Trustee in personal
liability.  Prior to taking any action under the Indenture, the Trustee shall
be entitled to indemnification satisfactory to it in its sole discretion
against all losses and expenses caused by taking or not taking such action.

15. Trustee Dealings with the Company

          Subject to certain limitations imposed by the TIA, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee.

16. No Recourse Against Others

                                 The Securities

                  SECTION 2.01. Amount of Securities; Issuable in Series. The
aggregate principal amount of Securities which may be authenticated and
delivered under this Indenture is $311,000,000. The Securities may be issued in
one or more series. All Securities of any one series shall be substantially
identical except as to denomination.

                  With respect to any Additional Securities issued after the
Closing Date (except for Securities authenticated and delivered upon
registration of transfer of, or in exchange for, or in lieu of, other Securities
pursuant to Section 2.07, 2.08, 2.09, 2.10 or 3.06 or the Appendix), there shall
be (i) established in or pursuant to a resolution of the Board of Directors and
(ii) (A) set forth or determined in the manner provided in an Officers'
Certificate or (B) established in one or more indentures supplemental hereto,
prior to the issuance of such Additional Securities:

                  (1) whether such Additional Securities shall be issued as part
         of a new or existing series of Securities and the title of such
         Additional Securities (which shall distinguish the Additional
         Securities of the series from Securities of any other series);

                  (2) the aggregate principal amount of such Additional
         Securities which may be authenticated and delivered under this
         Indenture, which shall be in an aggregate principal amount not to
         exceed $50,000,000 (except for Securities authenticated and delivered
         upon registration of transfer of, or in exchange for, or in lieu of,
         other Securities of the same series pursuant to Section 2.07, 2.08,
         2.09, 2.10 or 3.06 or the Appendix and except for Securities which,

         and delivered hereunder);

                  (3) the issue price and issuance date of such Additional
         Securities, including the date from which interest on such Additional
         Securities shall accrue; provided; however, that no Additional
         Securities may be issued at a price that

<PAGE>   24

                                                                              19


         would cause such Additional Securities to have "original issue
         discount" within the meaning of Section 1273 of the Code;

                  (4) if applicable, that such Additional Securities shall be
         issuable in whole or in part in the form of one or more Global
         Securities (as defined in the Appendix) and, in such case, the
         respective depositaries for such Global Securities, the form of any
         legend or legends which shall be borne by such Global Securities in
         addition to or in lieu of those set forth in Exhibit A hereto and any
         circumstances in addition to or in lieu of those set forth in Section
         2.3 of the Appendix in which any such Global Security may be exchanged
         in whole or in part for Additional Securities registered, or any
         transfer of such Global Security in whole or in part may be registered,
         in the name or names of Persons other than the depositary for such
         Global Security or a nominee thereof; and

                  (5) if applicable, that such Additional Securities shall not
         be issued in the form of Initial Securities as set forth in Exhibit A,
         but shall be issued in the form of Exchange Securities as set forth in
         Exhibit B.

                  If any of the terms of any Additional Securities are
established by action taken pursuant to a resolution of the Board of Directors,
a copy of an appropriate record of such action shall be certified by the
Secretary or any Assistant Secretary of the Company and delivered to the Trustee
at or prior to the delivery of the Officers' Certificate or the indenture
supplemental hereto setting forth the terms of the Additional Securities.

                  SECTION 2.02. Form and Dating. Provisions relating to the
Original Securities, the Additional Securities, the Private Exchange Securities
and the Exchange Securities are set forth in the Appendix, which is hereby
incorporated in and expressly made a part of this Indenture. The (i) Original
Securities and the Trustee's certificate of authentication, (ii) Private
Exchange Securities and the Trustee's certificate of authentication and (iii)
any Additional Securities (if issued as Transfer Restricted Securities (as
defined in the Appendix)) and the Trustee's certificate of authentication shall
each be substantially in the form of Exhibit A hereto, which is hereby
incorporated in and expressly made a part of this Indenture. The Exchange
Securities and any Additional Securities issued other than as Transfer
Restricted Securities and the Trustee's certificate of authentication shall each
be substantially in the form of Exhibit B hereto, which is hereby incorporated
in and expressly made a part of this Indenture. The Securities may have
notations, legends or endorsements required by law, stock exchange rule,
agreements to which the Company or any Subsidiary Guarantor is subject, if any,
or usage (provided that any such notation, legend or endorsement is in a form
acceptable to the Company). Each Security shall be dated the date of its
authentication. The Securities shall be issuable only in registered form without
coupons and only in denominations of $1,000 and integral multiples thereof.

                  SECTION 2.03. Execution and Authentication. One or more
Officers shall sign the Securities for the Company by manual or facsimile
signature.

                  If an Officer whose signature is on a Security no longer holds
that office at the time the Trustee authenticates the Security, the Security
shall be valid nevertheless.

                                                                              20


                  A Security shall not be valid until an authorized signatory of
the Trustee manually signs the certificate of authentication on the Security.
The signature shall be conclusive evidence that the Security has been
authenticated under this Indenture.

                  The Trustee shall authenticate and make available for delivery
Securities as set forth in the Appendix.

                  The Trustee may appoint an authenticating agent reasonably
acceptable to the Company to authenticate the Securities. Any such appointment
shall be evidenced by an instrument signed by a Trust Officer, a copy of which
shall be furnished to the Company. Unless limited by the terms of such
appointment, an authenticating agent may authenticate Securities whenever the
Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent has the
same rights as any Registrar, Paying Agent or agent for service of notices and
demands.

                  SECTION 2.04. Registrar and Paying Agent. The Company shall
maintain an office or agency where Securities may be presented for registration
of transfer or for exchange (the "Registrar") and an office or agency where
Securities may be presented for payment (the "Paying Agent"). The Registrar
shall keep a register of the Securities and of their transfer and exchange. The
Company may have one or more co-registrars and one or more additional paying
agents. The term "Paying Agent" includes any additional paying agent, and the
term "Registrar" includes any co-registrars. The Company initially appoints the
Trustee as (i) Registrar and Paying Agent in connection with the Securities and
(ii) the Securities Custodian (as defined in the Appendix) with respect to the
Global Securities.

                  The Company shall enter into an appropriate agency agreement
with any Registrar or Paying Agent not a party to this Indenture, which shall
incorporate the terms of the TIA. The agreement shall implement the provisions
of this Indenture that relate to such agent. The Company shall notify the
Trustee of the name and address of any such agent. If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.07. The
Company or any of its domestically organized Wholly Owned Subsidiaries may act
as Paying Agent or Registrar.

                  The Company may remove any Registrar or Paying Agent upon
written notice to such Registrar or Paying Agent and to the Trustee; provided,
however, that no such removal shall become effective until (1) acceptance of an
appointment by a successor as evidenced by an appropriate agreement entered into
by the Company and such successor Registrar or Paying Agent, as the case may be,
and delivered to the Trustee or (2) notification to the Trustee that the Trustee
shall serve as Registrar or Paying Agent until the appointment of a successor in
accordance with clause (1) above. The Registrar or Paying Agent may resign at
any time upon written notice; provided, however, that the Trustee may resign as
Paying Agent or Registrar only if the Trustee also resigns as Trustee in
accordance with Section 7.08.

                  SECTION 2.05. Paying Agent To Hold Money in Trust. Prior to
each due date of the principal and interest on any Security, the Company shall
deposit with the Paying Agent (or if the Company or a Subsidiary is acting as
Paying Agent, segregate and hold in trust for the benefit of the Persons
entitled thereto) a sum sufficient to pay

<PAGE>   26

                                                                              21


such principal and interest when so becoming due. The Company shall require each
Paying Agent (other than the Trustee) to agree in writing that the Paying Agent
shall hold in trust for the benefit of Securityholders or the Trustee all money
held by the Paying Agent for the payment of principal of or interest on the
Securities and shall notify the Trustee of any default by the Company in making
any such payment. If the Company or a Subsidiary of the Company acts as Paying
Agent, it shall segregate the money held by it as Paying Agent and hold it as a
separate trust fund. The Company at any time may require a Paying Agent to pay
all money held by it to the Trustee and to account for any funds disbursed by
the Paying Agent. Upon complying with this Section 2.05, the Paying Agent shall
have no further liability for the money delivered to the Trustee.

                  SECTION 2.06. Securityholder Lists. The Trustee shall preserve
in as current a form as is reasonably practicable the most recent list available
to it of the names and addresses of Securityholders. If the Trustee is not the
Registrar, the Company shall furnish, or cause the Registrar to furnish, to the
Trustee, in writing at least five Business Days before each interest payment
date and at such other times as the Trustee may request in writing, a list in
such form and as of such date as the Trustee may reasonably require of the names
and addresses of Securityholders.

                  SECTION 2.07. Transfer and Exchange. The Securities shall be
issued in registered form and shall be transferable only upon the surrender of a
Security for registration of transfer and in compliance with the Appendix. When
a Security is presented to the Registrar with a request to register a transfer,
the Registrar shall register the transfer as requested if the requirements of
Section 8-401(a) of the Uniform Commercial Code are met. When Securities are
presented to the Registrar with a request to exchange them for an equal
principal amount of Securities of other denominations, the Registrar shall make
the exchange as requested if the requirements of Section 8-401(a)(1) and (2) of
the Uniform Commercial Code are met. To permit registration of transfers and
exchanges, the Company shall execute and the Trustee shall authenticate
Securities at the Registrar's request. The Company may require payment of a sum
sufficient to pay all taxes, assessments or other governmental charges in
connection with any transfer or exchange pursuant to this Section 2.07. The
Company shall not be required to make and the Registrar need not register
transfers or exchanges of Securities selected for redemption (except, in the
case of Securities to be redeemed in part, the portion thereof not to be
redeemed) or any Securities for a period of 15 days before a selection of
Securities to be redeemed.

                  Prior to the due presentation for registration of transfer of
any Security, the Company, the Subsidiary Guarantors, if any, the Trustee, the
Paying Agent and the Registrar may deem and treat the Person in whose name a
Security is registered as the absolute owner of such Security for the purpose of
receiving payment of principal of and interest, if any, on such Security and for
all other purposes whatsoever, whether or not such Security is overdue, and none
of the Company, any Subsidiary Guarantor, the Trustee, the Paying Agent or the
Registrar shall be affected by notice to the contrary.

                  Any Holder of a Global Security shall, by acceptance of such
Global Security, agree that transfers of beneficial interest in such Global
Security may be effected only through a book-entry system maintained by (i) the
Holder of such Global Security (or its agent) or (ii) any Holder of a beneficial
interest in such Global Security, and that ownership of a beneficial interest in
such Global Security shall be required to be reflected in a book entry.

                                                                              22


                  All Securities issued upon any transfer or exchange pursuant
to the terms of this Indenture shall evidence the same debt and shall be
entitled to the same benefits under this Indenture as the Securities surrendered
upon such transfer or exchange.

                  SECTION 2.08. Replacement Securities. If a mutilated Security
is surrendered to the Registrar or if the Holder of a Security claims that the
Security has been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee shall authenticate a replacement Security if the requirements of
Section 8-405 of the Uniform Commercial Code are met, such that the Holder (i)
notifies the Company or the Trustee within a reasonable time after he has notice
of such loss, destruction or wrongful taking, and the Registrar does not
register a transfer prior to receiving such notification, (ii) makes such
request to the Company or the Trustee prior to the Security being acquired by a
protected purchaser as defined in Section 8-303 of the Uniform Commercial Code
(a "protected purchaser") and (iii) satisfies any other reasonable requirements
of the Trustee. If required by the Trustee or the Company, such Holder shall
furnish an indemnity bond sufficient in the judgment of the Trustee to protect
the Company, the Trustee, the Paying Agent and the Registrar from any loss that
any of them may suffer if a Security is replaced. The Company and the Trustee
may charge the Holder for their expenses in replacing a Security. In the event
any such mutilated, lost, destroyed or wrongfully taken Security has become or
is about to become due and payable, the Company in its discretion may pay such
Security instead of issuing a new Security in replacement thereof.

                  Every replacement Security is an additional obligation of the
Company.

                  The provisions of this Section 2.08 are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, lost, destroyed or wrongfully taken
Securities.

                  SECTION 2.09. Outstanding Securities. Securities outstanding
at any time are all Securities authenticated by the Trustee except for those
canceled by it, those delivered to it for cancelation and those described in
this Section as not outstanding. Subject to Section 11.06, a Security does not
cease to be outstanding because the Company or an Affiliate of the Company holds
the Security.

                  If a Security is replaced pursuant to Section 2.08, it ceases
to be outstanding unless the Trustee and the Company receive proof satisfactory
to them that the replaced Security is held by a protected purchaser.

                  If the Paying Agent segregates and holds in trust, in
accordance with this Indenture, on a redemption date or maturity date money
sufficient to pay all principal and interest payable on that date with respect
to the Securities (or portions thereof) to be redeemed or maturing, as the case
may be, then on and after that date such Securities (or portions thereof) cease
to be outstanding and interest on them ceases to accrue.

                  SECTION 2.10. Temporary Securities. In the event that
Definitive Securities (as defined in the Appendix) are to be issued under the
terms of this Indenture, until such Definitive Securities are ready for
delivery, the Company may prepare and the Trustee shall authenticate temporary
Securities. Temporary Securities shall be substantially in the form of
Definitive Securities but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the

<PAGE>   28
                                                                              23


Company shall prepare and the Trustee shall authenticate Definitive Securities
and deliver them in exchange for temporary Securities upon surrender of such
temporary Securities at the office or agency of the Company, without charge to
the Holder.

                  SECTION 2.11. Cancelation. The Company at any time may deliver
Securities to the Trustee for cancelation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment. The Trustee and no one else shall cancel all
Securities surrendered for registration of transfer, exchange, payment or
cancelation and deliver canceled Securities to the Company pursuant to written
direction by an Officer. The Company may not issue new Securities to replace
Securities it has redeemed, paid or delivered to the Trustee for cancelation.
The Trustee shall not authenticate Securities in place of canceled Securities
other than pursuant to the terms of this Indenture.

                  SECTION 2.12. Defaulted Interest. If the Company defaults in a
payment of interest on the Securities, the Company shall pay the defaulted
interest (plus interest on such defaulted interest to the extent lawful) in any
lawful manner. The Company may pay the defaulted interest to the Persons who are
Securityholders on a subsequent special record date. The Company shall fix or
cause to be fixed any such special record date and payment date to the
reasonable satisfaction of the Trustee and shall promptly mail or cause to be
mailed to each Securityholder a notice that states the special record date, the
payment date and the amount of defaulted interest to be paid.

                  SECTION 2.13. CUSIP Numbers. The Company in issuing the
Securities may use "CUSIP" numbers (if then generally in use) and, if so, the
Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to
Holders; provided, however, that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers.


                                    ARTICLE 3

                                   Redemption

                  SECTION 3.01. Notices to Trustee. If the Company elects to
redeem Securities pursuant to paragraph 5 of the Securities, it shall notify the
Trustee in writing of the redemption date and the principal amount of Securities
to be redeemed.

                  The Company shall give each notice to the Trustee provided for
in this Section 3.01 at least 60 days before the redemption date unless the
Trustee consents to a shorter period. Such notice shall be accompanied by an
Officers' Certificate and an Opinion of Counsel from the Company to the effect
that such redemption will comply with the conditions herein. If fewer than all
the Securities are to be redeemed, the record date relating to such redemption
shall be selected by the Company and given to the Trustee, which record date
shall be not fewer than 15 days after the date of notice to the Trustee. Any
such notice may be canceled at any time prior to notice of such redemption being
mailed to any Holder and shall thereby be void and of no effect.

                                                                              24


                  SECTION 3.02. Selection of Securities To Be Redeemed. If fewer
than all the Securities are to be redeemed, the Trustee shall select the
Securities to be redeemed pro rata or by lot or by a method that complies with
applicable legal and securities exchange requirements, if any, and that the
Trustee in its sole discretion shall deem to be fair and appropriate and in
accordance with methods generally used at the time of selection by fiduciaries
in similar circumstances. The Trustee shall make the selection from outstanding
Securities not previously called for redemption. The Trustee may select for
redemption portions of the principal of Securities that have denominations
larger than $1,000. Securities and portions of them the Trustee selects shall be
in amounts of $1,000 or a whole multiple of $1,000. Provisions of this Indenture
that apply to Securities called for redemption also apply to portions of
Securities called for redemption. The Trustee shall notify the Company promptly
of the Securities or portions of Securities to be redeemed.

                  SECTION 3.03. Notice of Redemption. At least 30 days but not
more than 60 days before a date for redemption of Securities, the Company shall
mail a notice of redemption by first-class mail to each Holder of Securities to
be redeemed at such Holder's registered address.

                  The notice shall identify the Securities to be redeemed and
shall state:

                  (1) the redemption date;

                  (2) the redemption price and the amount of accrued interest to
         the redemption date;

                  (3) the name and address of the Paying Agent;

                  (4) that Securities called for redemption must be surrendered
         to the Paying Agent to collect the redemption price;

                  (5) if fewer than all the outstanding Securities are to be
         redeemed, the certificate numbers and principal amounts of the
         particular Securities to be redeemed;

                  (6) that, unless the Company defaults in making such
         redemption payment or the Paying Agent is prohibited from making such
         payment pursuant to the terms of this Indenture, interest on Securities
         (or portion thereof) called for redemption ceases to accrue on and
         after the redemption date;

                  (7) the CUSIP number, if any, printed on the Securities being
         redeemed; and

                  (8) that no representation is made as to the correctness or
         accuracy of the CUSIP number, if any, listed in such notice or printed
         on the Securities.

                  At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense. In such event,
the Company shall provide the Trustee with the information required by this
Section.

                  SECTION 3.04. Effect of Notice of Redemption. Once notice of
redemption is mailed, Securities called for redemption become due and payable on
the redemption date and at the redemption price stated in the notice. Upon
surrender to the Paying Agent, such Securities shall be paid at the redemption
price stated in the notice, plus accrued interest, if any, to the redemption
date; provided, however, that if the redemption date is after a regular record
date and on or prior to the interest payment date, the accrued interest shall be
payable to the Securityholder of the redeemed Securities registered on the
relevant record date. Failure to give notice or any defect in the notice to any
Holder shall not affect the validity of the notice to any other Holder.

                  SECTION 3.05. Deposit of Redemption Price. Prior to 10:00 a.m.
on the redemption date, the Company shall deposit with the Paying Agent (or, if
the Company or a Subsidiary is the Paying Agent, shall segregate and hold in
trust) money sufficient to pay the redemption price of and accrued interest on
all Securities to be redeemed on that date other than Securities or portions of
Securities called for redemption that have been delivered by the Company to the
Trustee for cancelation.

                  SECTION 3.06. Securities Redeemed in Part. Upon surrender of a
Security that is redeemed in part, the Company shall execute and the Trustee
shall authenticate for the Holder (at the Company's expense) a new Security
equal in principal amount to the unredeemed portion of the Security surrendered.

                                    Covenants

                  SECTION 4.01. Payment of Securities. The Company shall
promptly pay the principal of and interest on the Securities on the dates and in
the manner provided in the Securities and in this Indenture. Principal and
interest shall be considered paid on the date due if on such date the Trustee or
the Paying Agent holds in accordance with this Indenture money sufficient to pay
all principal and interest then due and the Trustee or the Paying Agent, as the
case may be, is not prohibited from paying such money to the Securityholders on
that date pursuant to the terms of this Indenture.

                  The Company shall pay interest on overdue principal at the
rate specified therefor in the Securities, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

                  SECTION 4.02. SEC Reports. Notwithstanding that the Company
may not be subject to the reporting requirements of Section 13 or 15(d) of the
Exchange Act the Company shall file with the SEC and provide the Trustee and
Securityholders and prospective Securityholders (upon request) within 15 days
after it files them with the SEC, copies of its annual report and the
information, documents and other reports that are specified in Sections 13 and
15(d) of the Exchange Act. In addition, following a public offering of the
common stock of the Company, the Company shall furnish to the Trustee and the
Securityholders, promptly upon their becoming available, copies of the annual
report to stockholders and any other information provided by the Company to its
public stockholders generally. The Company also shall comply with the other
provisions of Section 314(a) of the TIA.

                  SECTION 4.03. Limitation on Indebtedness. (a) The Company
shall not, and shall not permit any Restricted Subsidiary to, Incur, directly or
indirectly, any Indebtedness; provided, however, that the Company may Incur
Indebtedness if on the date of such Incurrence and after giving effect thereto
the Debt to Annualized Operating Cash Flow Ratio would be less than or equal to
6.0:1.0 if such Indebtedness is Incurred prior to July 15, 2001 and less than or
equal to 5.5:1.0 if such Indebtedness is Incurred on or after such date.

         (b) Notwithstanding Section 4.03(a), the Company and its Restricted
Subsidiaries may Incur the following Indebtedness:

                  (i) Bank Indebtedness in an aggregate principal amount not to
         exceed $75.0 million less the aggregate amount of all repayments of
         principal applied to permanently reduce any such Indebtedness;

                  (ii) Indebtedness of the Company owed to and held by any
         Wholly Owned Subsidiary or Indebtedness of a Restricted Subsidiary owed
         to and held by the Company or any Wholly Owned Subsidiary; provided,
         however, that (i) any subsequent issuance or transfer of any Capital
         Stock or any other event that results in any such Wholly Owned
         Subsidiary ceasing to be a Wholly Owned Subsidiary or any subsequent
         transfer of any such Indebtedness (except to the Company or a Wholly
         Owned Subsidiary) shall be deemed, in each case, to constitute the
         Incurrence of such Indebtedness by the issuer thereof and (ii) if the
         Company is the obligor on such Indebtedness, such Indebtedness is
         expressly subordinated to the prior payment in full in cash of all
         obligations with respect to the Securities;

                  (iii) Indebtedness (A) represented by the Securities (not
         including any Additional Securities), (B) outstanding on the Closing
         Date (other than the Indebtedness described in clauses (i) and (ii)
         above), (C) consisting of Refinancing Indebtedness Incurred in respect
         of any Indebtedness described in this clause (iii) (including
         Indebtedness Refinancing Refinancing Indebtedness) or Section 4.03(a),
         (D) consisting of Guarantees of any Indebtedness permitted under
         clauses (i) and (ii) of this paragraph (b) and (E) consisting of any
         Guarantees of the Securities;

                  (iv) (A) Indebtedness of a Restricted Subsidiary Incurred and
         outstanding on or prior to the date on which such Restricted Subsidiary
         was acquired by the Company (other than Indebtedness Incurred as
         consideration in, or to provide all or any portion of the funds or
         credit support utilized to consummate, the transaction or series of
         related transactions pursuant to which such Restricted Subsidiary
         became a Subsidiary of or was otherwise acquired by the Company);
         provided, however, that on the date that such Restricted Subsidiary is
         acquired by the Company, the Company would have been able to Incur
         $1.00 of additional Indebtedness pursuant to Section 4.03(a) after
         giving effect to the Incurrence of such Indebtedness pursuant to this
         clause (iv) and (B) Refinancing Indebtedness Incurred by a Restricted
         Subsidiary in respect of Indebtedness Incurred by such Restricted
         Subsidiary pursuant to this clause (iv);

                  (v) Indebtedness (A) in respect of performance bonds, bankers'
         acceptances, letters of credit and surety or appeal bonds provided by
         the Company and the Restricted Subsidiaries in the ordinary course of
         their business and 

<PAGE>   32
                                                                              27


         (B) under Hedging Obligations entered into for bona fide hedging
         purposes of the Company in the ordinary course of business; provided,
         however, that such Hedging Obligations do not increase the Indebtedness
         of the Company outstanding at any time other than as a result of
         fluctuations in interest rates or currency exchange rates or by reason
         of fees, indemnities and compensation payable thereunder;

                  (vi) Purchase Money Indebtedness, provided that the amount of
         such Purchase Money Indebtedness does not exceed the lesser of 80% of
         (a) the Fair Market Value of or (b) the cost of the construction,
         installation, acquisition, lease, development or improvement of, the
         applicable Telecommunications Assets;

                  (vii) Contribution Indebtedness; or

                  (viii) Indebtedness (other than Indebtedness permitted to be
         Incurred pursuant to Section 4.03(a) or any other clause of this
         Section 4.03(b)) in an aggregate principal amount on the date of
         Incurrence that, when added to all other Indebtedness Incurred pursuant
         to this clause (viii) and then outstanding, shall not exceed $40.0
         million.

         (c) Notwithstanding the foregoing, the Company may not Incur any
Indebtedness pursuant to Section 4.03(b) if the proceeds thereof are used,
directly or indirectly, to repay, prepay, redeem, defease, retire, refund or
refinance any Subordinated Obligations unless such Indebtedness will be
subordinated to the Securities to at least the same extent as such Subordinated
Obligations.

         (d) Notwithstanding any other provision of this Section 4.03, the
maximum amount of Indebtedness that the Company or any Restricted Subsidiary may
Incur pursuant to this Section 4.03 shall not be deemed to be exceeded solely as
a result of fluctuations in the exchange rates of currencies. For purposes of
determining the outstanding principal amount of any particular Indebtedness
Incurred pursuant to this Section 4.03, (i) Indebtedness permitted by this
Section 4.03 need not be permitted solely by reference to one provision
permitting such Indebtedness but may be permitted in part by one such provision
and in part by one or more other provisions of this Section 4.03 permitting such
Indebtedness and (ii) in the event that Indebtedness meets the criteria of more
than one of the types of Indebtedness described in Section 4.03(b), the Company,
in its sole discretion, shall classify such Indebtedness and only be required to
include the amount of such Indebtedness in one of such clauses. Once so
classified, such Indebtedness shall retain such classification until repaid.

                  SECTION 4.04. Limitation on Restricted Payments. (a) The
Company shall not, and shall not permit any Restricted Subsidiary, directly or
indirectly, to (i) declare or pay any dividend or make any distribution on or in
respect of its Capital Stock (including any payment in connection with any
merger or consolidation involving the Company) or similar payment to the direct
or indirect holders of its Capital Stock except dividends or distributions
payable solely in its Capital Stock (other than Disqualified Stock) and except
dividends or distributions payable to the Company or another Restricted
Subsidiary (and, if such Restricted Subsidiary has stockholders other than the
Company or other Restricted Subsidiaries, to its other stockholders on a pro
rata basis), (ii) purchase, redeem, retire or otherwise acquire for value any
Capital Stock of the Company or any Restricted Subsidiary held by Persons other
than the Company or

another Restricted Subsidiary, (iii) purchase, repurchase, redeem, defease or
otherwise acquire or retire for value, prior to scheduled maturity, scheduled
repayment or scheduled sinking fund payment any Subordinated Obligations (other
than the purchase, repurchase or other acquisition of Subordinated Obligations
purchased in anticipation of satisfying a sinking fund obligation, principal
installment or final maturity, in each case due within one year of the date of
acquisition) or (iv) make any Investment (other than a Permitted Investment) in
any Person (any such dividend, distribution, purchase, redemption, repurchase,
defeasance, other acquisition, retirement or Investment being herein referred to
as a "Restricted Payment") if at the time the Company or such Restricted
Subsidiary makes such Restricted Payment:

                  (1) a Default shall have occurred and be continuing (or would
         result therefrom);

                  (2) the Company could not Incur at least $1.00 of additional
         Indebtedness pursuant to Section 4.03(a); or

                  (3) the aggregate amount of such Restricted Payment and all
         other Restricted Payments (the amount so expended, if other than in
         cash, to be determined in good faith by the Board of Directors, whose
         determination shall be conclusive and evidenced by a resolution of the
         Board of Directors) declared or made subsequent to the Closing Date
         would exceed the sum of: (A) (i) 100% of Consolidated Operating Cash
         Flow accrued during the period (treated as one accounting period) from
         the beginning of the fiscal quarter immediately following the fiscal
         quarter during which the Closing Date occurs to the end of the most
         recent fiscal quarter ending at least 45 days prior to the date of such
         Restricted Payment (or, in case such Consolidated Operating Cash Flow
         during such period is a deficit, minus 100% of such deficit), minus
         (ii) 150% of Consolidated Interest Expense accrued during the period
         (treated as one accounting period) from the beginning of the fiscal
         quarter immediately following the fiscal quarter during which the
         Closing Date occurs to the end of the most recent fiscal quarter ending
         at least 45 days prior to the date of such Restricted Payment; plus,
         (B) the aggregate Net Cash Proceeds received by the Company from the
         issue or sale of its Capital Stock (other than Disqualified Stock)
         subsequent to the Closing Date (other than an issuance or sale to (x) a
         Subsidiary of the Company or (y) an employee stock ownership plan or
         other trust established by the Company or any of its Subsidiaries);
         plus, (C) the amount by which Indebtedness of the Company or its
         Restricted Subsidiaries is reduced on the Company's balance sheet upon
         the conversion or exchange (other than by a Subsidiary of the Company)
         subsequent to the Closing Date of any Indebtedness of the Company or
         its Restricted Subsidiaries issued after the Closing Date which is
         convertible or exchangeable for Capital Stock (other than Disqualified
         Stock) of the Company (less the amount of any cash or the fair market
         value of other property distributed by the Company or any Restricted
         Subsidiary upon such conversion or exchange); plus, (D) the amount
         equal to the net reduction in Investments in Unrestricted Subsidiaries
         resulting from (i) payments of dividends, repayments of the principal
         of loans or advances or other transfers of assets to the Company or any
         Restricted Subsidiary from Unrestricted Subsidiaries or (ii) the
         redesignation of Unrestricted Subsidiaries as Restricted Subsidiaries
         (valued in each case as provided in the definition of "Investment") not
         to exceed, in the case of any Unrestricted Subsidiary, the amount of
         Investments previously made by the Company or any

<PAGE>   34
                                                                              29


         Restricted Subsidiary in such Unrestricted Subsidiary, which amount was
         included in the calculation of the amount of Restricted Payments; and
         less, (E) the aggregate principal amount of any outstanding
         Contribution Indebtedness or, if less, the Cash Contribution Amount.

         (b) The provisions of Section 4.04(a) shall not prohibit: (i) any
purchase, repurchase, retirement or other acquisition or retirement for value of
Capital Stock of the Company made by exchange for, or out of the proceeds of the
substantially concurrent sale of, Capital Stock of the Company (other than
Disqualified Stock and other than Capital Stock issued or sold to a Subsidiary
of the Company or an employee stock ownership plan or other trust established by
the Company or any of its Subsidiaries); provided, however, that such purchase,
repurchase, retirement or other acquisition or retirement for value shall be
excluded in the calculation of the amount of Restricted Payments; (ii) any
purchase, repurchase, redemption, defeasance or other acquisition or retirement
for value of Subordinated Obligations of the Company made by exchange for, or
out of the proceeds of the substantially concurrent sale of, Indebtedness of the
Company that is permitted to be Incurred pursuant to Section 4.03(b) or Capital
Stock of the Company (other than Disqualified Stock and other than Capital Stock
issued or sold to a Subsidiary of the Company or an employee stock ownership
plan or other trust established by the Company or any of its Subsidiaries);
provided, however, that such purchase, repurchase, redemption, defeasance or
other acquisition or retirement for value shall be excluded in the calculation
of the amount of Restricted Payments; (iii) any purchase or redemption of
Subordinated Obligations from Net Available Cash to the extent permitted by
Section 4.06; provided, however, that such purchase or redemption shall be
included in the calculation of the amount of Restricted Payments; (iv) dividends
paid within 60 days after the date of declaration thereof if at such date of
declaration such dividend would have complied with this Section 4.04; provided,
however, that such dividend shall be included in the calculation of the amount
of Restricted Payments; or (v) the repurchase or other acquisition of shares of,
or options to purchase shares of, common stock of the Company or any of its
Subsidiaries from employees, former employees, directors or former directors of
the Company or any of its Subsidiaries (or permitted transferees of such
employees, former employees, directors or former directors), pursuant to the
terms of agreements (including employment agreements) or plans (or amendments
thereto) approved by the Board of Directors under which such individuals
purchase or sell or are granted the option to purchase or sell, shares of such
common stock; provided, however, that the aggregate amount of such repurchases
shall not exceed $1.0 million in any calendar year and $3.0 million in the
aggregate; provided further, that such repurchases and other acquisitions shall
be included in the calculation of the amount of Restricted Payments.

                  SECTION 4.05. Limitation on Restrictions on Distributions from
Restricted Subsidiaries. The Company shall not, and shall not permit any
Restricted Subsidiary to, create or otherwise cause or permit to exist or become
effective any consensual encumbrance or restriction on the ability of any
Restricted Subsidiary to (i) pay dividends or make any other distributions on
its Capital Stock or pay any Indebtedness or other obligations owed to the
Company, (ii) make any loans or advances to the Company or (iii) transfer any of
its property or assets to the Company, except:

                  (1) any encumbrance or restriction pursuant to (A) an
         agreement in effect at or entered into on the Closing Date or (B) an
         agreement entered into in connection with the Incurrence of
         Indebtedness permitted under clause (b)(i) or

<PAGE>   35
                                                                              30


         (b)(vi) of Section 4.03, provided that the chief financial officer of
         the Company has determined in good faith that any restriction incurred
         pursuant to this clause (B) is customary for similar Incurrences of
         Indebtedness;

                  (2) any encumbrance or restriction with respect to a
         Restricted Subsidiary pursuant to an agreement relating to any
         Indebtedness Incurred by such Restricted Subsidiary prior to the date
         on which such Restricted Subsidiary was acquired by the Company (other
         than Indebtedness Incurred as consideration in, in contemplation of,
         or to provide all or any portion of the funds or credit support
         utilized to consummate the transaction or series of related
         transactions pursuant to which such Restricted Subsidiary became a
         Restricted Subsidiary or was otherwise acquired by the Company) and
         outstanding on such date;

                  (3) any encumbrance or restriction pursuant to an agreement
         effecting a Refinancing of Indebtedness Incurred pursuant to an
         agreement referred to in clause (1) or (2) of this Section 4.05 or this
         clause (3) or contained in any amendment to an agreement referred to in
         clause (1) or (2) of this Section 4.05 or this clause (3); provided,
         however, that the encumbrances and restrictions contained in any such
         refinancing agreement or amendment are no less favorable to the
         Securityholders than the encumbrances and restrictions contained in
         such predecessor agreements;

                  (4) in the case of clause (iii), any encumbrance or
         restriction (A) that restricts in a customary manner the subletting,
         assignment or transfer of any property or asset that is subject to a
         lease, license or similar contract, or (B) contained in security
         agreements securing Indebtedness of a Restricted Subsidiary to the
         extent such encumbrance or restriction restricts the transfer of the
         property subject to such security agreements; and

                  (5) with respect to a Restricted Subsidiary, any restriction
         imposed pursuant to an agreement entered into for the sale or
         disposition of all or substantially all the Capital Stock or assets of
         such Restricted Subsidiary pending the closing of such sale or
         disposition.

                  SECTION 4.06. Limitation on Sales of Assets and Subsidiary
Stock. (a) The Company shall not, and shall not permit any Restricted Subsidiary
to, make any Asset Disposition unless (i) the Company or such Restricted
Subsidiary receives consideration (including by way of relief from, or by any
other Person assuming sole responsibility for, any liabilities, contingent or
otherwise) at the time of such Asset Disposition at least equal to the Fair
Market Value of the shares and assets subject to such Asset Disposition, (ii) at
least 75% of the consideration thereof received by the Company or such
Restricted Subsidiary is in the form of cash or cash equivalents and (iii) an
amount equal to 100% of the Net Available Cash from such Asset Disposition is
applied by the Company (or such Restricted Subsidiary, as the case may be) (A)
first, to the extent the Company elects (or is required by the terms of any Bank
Indebtedness) to (x) reinvest in Telecommunications Assets (including by means
of an Investment in Telecommunications Assets by a Restricted Subsidiary with
Net Available Cash received by the Company or another Restricted Subsidiary) or
(y) prepay, repay, redeem or purchase Bank Indebtedness of the Company Incurred
pursuant to Section 4.03(b)(i), in each case within 180 days after the later of
the date of such Asset Disposition or the receipt of such Net Available Cash;
(B) second, to the extent of the balance of such Net

                                                                              31


Available Cash after application in accordance with clause (A), to make an Offer
(as defined below) to purchase Securities pursuant to and subject to the
conditions set forth in Section 4.06(c) within 365 days after the later of such
Asset Disposition or the receipt of such Net Available Cash; provided, however,
that if the Company elects (or is required by the terms of any other Senior
Indebtedness), such Offer may be made ratably to purchase the Securities and
other Senior Indebtedness of the Company, and (C) third, to fund (to the extent
consistent with any other applicable provision in this Indenture) any corporate
purpose. Notwithstanding the foregoing provisions of this Section 4.06, the
Company and the Restricted Subsidiaries shall not be required to apply any Net
Available Cash in accordance with this Section 4.06 except to the extent that
the aggregate Net Available Cash from all Asset Dispositions that is not applied
in accordance with this Section 4.06 exceeds $5.0 million.

         (b) For the purposes of this Section 4.06, the following are deemed to
be cash: (x) the assumption of Indebtedness of the Company (other than
Disqualified Stock of the Company) or any Restricted Subsidiary and the release
of the Company or such Restricted Subsidiary from all liability on such
Indebtedness in connection with such Asset Disposition and (y) securities
received by the Company or any Restricted Subsidiary from the transferee that
are converted by the Company or such Restricted Subsidiary into cash within 60
days of such receipt.

         (c) In the event of an Asset Disposition that requires the purchase of
Securities (and other Senior Indebtedness) pursuant to Section 4.06(a)(iii)(B),
the Company shall be required to purchase Securities (and other Senior
Indebtedness) tendered pursuant to an offer by the Company for the Securities
(and other Senior Indebtedness) (the "Offer") at a purchase price of 100% of
their principal amount plus accrued and unpaid interest and liquidated damages,
if any, to the date of purchase in accordance with the procedures (including
prorating in the event of oversubscription) set forth in Section 4.06(d). If the
aggregate purchase price of Securities (and other Senior Indebtedness) tendered
pursuant to the Offer is less than the Net Available Cash allotted to the
purchase of the Securities (and other Senior Indebtedness), the Company may
apply the remaining Net Available Cash in accordance with Section
4.06(a)(iii)(C). The Company shall not be required to make an Offer for
Securities (and other Senior Indebtedness) pursuant to this Section 4.06 if the
Net Available Cash available therefor (after application of the proceeds as
provided in Section 4.06(a)(iii)(A)) is less than $5.0 million for any
particular Asset Disposition (which lesser amount shall be carried forward for
purposes of determining whether an Offer is required with respect to the Net
Available Cash from any subsequent Asset Disposition).

         (d) (1) Promptly, and in any event within 10 days after the Company
becomes obligated to make an Offer, the Company shall be obligated to deliver to
the Trustee and send, by first-class mail to each Holder, a written notice
stating that the Holder may elect to have his Securities purchased by the
Company either in whole or in part (subject to prorationing as hereinafter
described in the event the Offer is oversubscribed) in integral multiples of
$1,000 of principal amount, at the applicable purchase price. The notice shall
specify a purchase date not less than 30 days nor more than 60 days after the
date of such notice (the "Purchase Date") and shall contain such information
concerning the business of the Company which the Company in good faith believes
will enable such Holders to make an informed decision (which at a minimum shall
include (i) the most recently filed Annual Report on Form 10-K (including
audited consolidated financial statements) of the Company, the most recent
subsequently filed Quarterly Report on

<PAGE>   37
                                                                              32


Form 10-Q and any Current Report on Form 8-K of the Company filed subsequent to
such Quarterly Report, other than Current Reports describing Asset Dispositions
otherwise described in the offering materials (or corresponding successor
reports), (ii) a description of material developments in the Company's business
subsequent to the date of the latest of such reports, and (iii) if material,
appropriate pro forma financial information) and all instructions and materials
necessary to tender Securities pursuant to the Offer, together with the address
referred to in clause (3) below.

                  (2) Not later than the date upon which written notice of an
Offer is delivered to the Trustee as provided above, the Company shall deliver
to the Trustee an Officers' Certificate as to (i) the amount of the Offer (the
"Offer Amount"), (ii) the allocation of the Net Available Cash from the Asset
Dispositions pursuant to which such Offer is being made and (iii) the compliance
of such allocation with the provisions of Section 4.06(a). On such date, the
Company shall also irrevocably deposit with the Trustee or with a Paying Agent
(or, if the Company is acting as its own Paying Agent, segregate and hold in
trust) an amount equal to the Offer Amount to be invested in Temporary Cash
Investments and to be held for payment in accordance with the provisions of
this Section. Upon the expiration of the period for which the Offer remains open
(the "Offer Period"), the Company shall deliver to the Trustee for cancelation
the Securities or portions thereof that have been properly tendered to and are
to be accepted by the Company. The Trustee (or the Paying Agent, if not the
Trustee) shall, on the date of purchase, mail or deliver payment to each
tendering Holder in the amount of the purchase price. In the event that the
aggregate purchase price of the Securities delivered by the Company to the
Trustee is less than the Offer Amount applicable to the Securities, the Trustee
shall deliver the excess to the Company immediately after the expiration of the
Offer Period for application in accordance with this Section 4.06.

                  (3) Holders electing to have a Security purchased shall be
required to surrender the Security, with an appropriate form duly completed, to
the Company at the address specified in the notice at least three Business Days
prior to the Purchase Date. Holders shall be entitled to withdraw their election
if the Trustee or the Company receives not later than one Business Day prior to
the Purchase Date, a telegram, telex, facsimile transmission or letter setting
forth the name of the Holder, the principal amount of the Security which was
delivered by the Holder for purchase and a statement that such Holder is
withdrawing his election to have such Security purchased. If at the expiration
of the Offer Period the aggregate principal amount of Securities included in the
Offer surrendered by holders thereof exceeds the Offer Amount, the Company shall
select the Securities to be purchased on a pro rata basis (with such adjustments
as may be deemed appropriate by the Company so that only Securities in
denominations of $1,000, or integral multiples thereof, shall be purchased).
Holders whose Securities are purchased only in part will be issued new
Securities equal in principal amount to the unpurchased portion of the
Securities surrendered.

                  (4) At the time the Company delivers Securities to the Trustee
which are to be accepted for purchase, the Company shall also deliver an
Officers' Certificate stating that such Securities are to be accepted by the
Company pursuant to and in accordance with the terms of this Section. A Security
shall be deemed to have been accepted for purchase at the time the Trustee,
directly or through an agent, mails or delivers payment therefor to the
surrendering Holder.

                  (d) The Company shall comply, to the extent applicable, with
the requirements of Section 14(e) of the Exchange Act and any other securities
laws or regulations in connection with the repurchase of Securities pursuant to
this Section 4.06. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section, the Company shall comply
with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations under this Section by virtue thereof.

                  SECTION 4.07. Limitation on Transactions with Affiliates. (a)
The Company shall not, and shall not permit any Restricted Subsidiary to,
directly or indirectly, enter into or conduct any transaction (including the
purchase, sale, lease or exchange of any property or the rendering of any
service) with any Affiliate of the Company (an "Affiliate Transaction") unless
such transaction is on terms (i) that are no less favorable to the Company or
such Restricted Subsidiary, as the case may be, than those that could be
obtained at the time of such transaction in arm's-length dealings with a Person
who is not such an Affiliate, (ii) that, in the event such Affiliate Transaction
involves an aggregate amount in excess of $1.0 million, (1) are set forth in
writing and (2) have been approved by a majority of the members of the Board of
Directors having no personal stake in such Affiliate Transaction and (iii) that,
in the event such Affiliate Transaction involves an amount in excess of $20.0
million, have been determined by a nationally recognized appraisal or investment
banking firm to be fair, from a financial standpoint, to the Company and its
Restricted Subsidiaries.

         (b) The provisions of Section 4.07(a) shall not prohibit (i) any
Restricted Payment permitted to be paid pursuant Section 4.04, (ii) any issuance
of securities, or other payments, awards or grants in cash, securities or
otherwise pursuant to, or the funding of, employment arrangements, stock options
and stock ownership plans approved by the Board of Directors, (iii) the grant of
stock options or similar rights to employees and directors of the Company
pursuant to plans approved by the Board of Directors, (iv) loans or advances to
employees in the ordinary course of business in accordance with past practices
of the Company, but in any event not to exceed $2.0 million in the aggregate
outstanding at any one time, (v) the payment of reasonable fees to directors of
the Company and its Subsidiaries, if any, who are not employees of the Company
or its Subsidiaries, if any, (vi) any transaction between the Company and a
Wholly Owned Subsidiary or between Wholly Owned Subsidiaries or (vii) any
transaction pursuant to, and on the terms set forth in, the Prodigy Agreement.

                  SECTION 4.08. Change of Control. (a) Upon the occurrence of a
Change of Control, each Holder shall have the right to require the Company to
repurchase all or any part of such Holder's Securities at a purchase price in
cash equal to 101% of the principal amount thereof plus accrued and unpaid
interest and liquidated damages, if any, to the date of repurchase (subject to
the right of Holders of record on the relevant record date to receive interest
due on the relevant interest payment date); provided, however, that
notwithstanding the occurrence of a Change of Control, the Company shall not be
obligated to repurchase the Securities pursuant to this Section 4.08 in the
event that it has exercised its right to redeem all the Securities under
paragraph 5 of the Securities.

                  (b) Within 30 days following any Change of Control, the
Company shall mail a notice to each Holder with a copy to the Trustee (the
"Change of Control Offer") stating: (1) that a Change of Control has occurred
and that such Holder has the right to require the Company to purchase such
Holder's Securities at a purchase price in cash

financial information regarding such Change of Control; (3) the repurchase date
(which shall be no earlier than 30 days nor later than 60 days from the date

its Securities purchased.

                  (c) Holders electing to have a Security purchased shall be
required to surrender the Security, with an appropriate form duly completed, to
the Company at the address specified in the notice at least three Business Days
prior to the purchase date. Holders shall be entitled to withdraw their election
if the Trustee or the Company receives not later than one Business Day prior to
the purchase date a telegram, telex, facsimile transmission or letter setting
forth the name of the Holder, the principal amount of the Security which was
delivered for purchase by the Holder and a statement that such Holder is
withdrawing his election to have such Security purchased.

                  (d) On the purchase date, all Securities purchased by the
Company under this Section 4.08 shall be delivered to the Trustee for
cancelation, and the Company shall pay the purchase price plus accrued and
unpaid interest, if any, to the Holders entitled thereto.

                  (e) Notwithstanding the forgoing provisions of this Section
4.08, the Company shall not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in this Indenture applicable to a Change of Control Offer made by the Company
and purchases all Securities validly tendered and not withdrawn under such
Change of Control Offer.

the requirements of Section 14(e) of the Exchange Act and any other securities
laws or regulations in connection with the repurchase of Securities pursuant to
this Section 4.08. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section 4.08, the Company shall

thereof.

Guarantor by executing and delivering to the Trustee a supplemental indenture
substantially in the form of Exhibit C hereto pursuant to which such Restricted
Subsidiary shall Guarantee payment of the Securities. Each Subsidiary Guarantee

Guarantee, as it relates to such Restricted Subsidiary, voidable under
applicable law relating to fraudulent conveyance or fraudulent transfer or
similar laws affecting the rights of creditors generally.

purposes of this proviso, shares of Capital Stock issued in connection with
customary accelerated vesting provisions contained in option or similar plans or
agreements which are accelerated as a result of a change of control of such
Person and which option or similar plans or agreements were not adopted or
implemented solely in anticipation of or in connection with such transaction) or

with (or prior to) the obligations so secured for so long as such obligations
are so secured; provided, that if such obligations are expressly subordinated to

                  (iii) immediately after giving effect to such transaction, the

         the case if such transaction had not occurred; and

                  (vi) the Company shall have delivered to the Trustee an
         Opinion of Counsel (subject to customary exceptions) to the effect that

         supplemental indenture and other appropriate documents, executed and
         delivered to the Trustee, in form satisfactory to the Trustee, all the
         obligations of such Subsidiary Guarantor under its Subsidiary
         Guarantee;

                  (ii) immediately after giving effect to such transaction (and
         treating any Indebtedness which becomes an obligation of the resulting,
         surviving or transferee Person as a result of such transaction as
         having been incurred by such Person at the time of such transaction),
         no Default shall have occurred and be continuing; and

                  (8) a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that:

                           (A) is for relief against the Company or any

                  (9) any judgment or decree for the payment of money in excess

         entered against the Company or any Significant Subsidiary and is not
         discharged, waived or stayed and either (A) an enforcement proceeding
         has been commenced by any creditor upon such judgment or decree or (B)

                  (11) the Company challenges the Lien on the Escrow Collateral

         Escrow Collateral is to be released to the Company, the Escrow
         Collateral becomes subject to any Lien other than Liens under the
         Escrow Agreement or the Escrow and Disbursement Agreement becomes, or
         the Company asserts that the Escrow and Disbursement Agreement is,
         invalid and unenforceable, other than in accordance with its terms.

                  The foregoing shall constitute Events of Default whatever the
reason for any such Event of Default and whether it is voluntary or involuntary
or is effected by operation of law or pursuant to any judgment, decree or order
of any court or any order, rule or regulation of any administrative or
governmental body.

                  The term "Bankruptcy Law" means Title 11, United States Code,
or any similar Federal or state law for the relief of debtors. The term
"Custodian" means any receiver, trustee, assignee, liquidator, custodian or
similar official under any Bankruptcy Law.

                  A Default under clause (4), (5), (6) or (10) above is not an
Event of Default until the Trustee or the Holders of at least 25% in principal
amount of the outstanding Securities notify the Company of the Default and the
Company does not cure such Default within the time specified after receipt of
such notice. Such notice must

<PAGE>   45
                                                                              40


specify the Default, demand that it be remedied and state that such notice is a
"Notice of Default".

                  The Company shall deliver to the Trustee, within 30 days after
the occurrence thereof, written notice in the form of an Officers' Certificate
of any Event of Default under clause (6), (10) and (11) and any event which with
the giving of notice or the lapse of time would become an Event of Default under
clause (4), (5) or (9), its status and what action the Company is taking or
proposes to take with respect thereto.

                  SECTION 6.02. Acceleration. If an Event of Default (other than
an Event of Default specified in Section 6.01(7) or (8) with respect to the
Company) occurs and is continuing, the Trustee by notice to the Company, or the
Holders of at least 25% in principal amount of the outstanding Securities by
notice to the Company, may declare the principal of and accrued but unpaid
interest on all the Securities to be due and payable. Upon such a declaration,
such principal and interest shall be due and payable immediately. If an Event of
Default specified in Section 6.01(7) or (8) with respect to the Company occurs,
the principal of and interest on all the Securities shall ipso facto become and
be immediately due and payable without any declaration or other act on the part
of the Trustee or any Securityholders. The Holders of a majority in principal
amount of the Securities by notice to the Trustee may rescind an acceleration
and its consequences if the rescission would not conflict with any judgment or
decree and if all existing Events of Default have been cured or waived except
nonpayment of principal or interest that has become due solely because of
acceleration. No such rescission shall affect any subsequent Default or impair
any right consequent thereto.

                  SECTION 6.03. Other Remedies. If an Event of Default occurs
and is continuing, the Trustee may pursue any available remedy to collect the
payment of principal of or interest on the Securities or to enforce the
performance of any provision of the Securities, this Indenture or the Escrow and
Disbursement Agreement.

                  The Trustee may maintain a proceeding even if it does not
possess any of the Securities or does not produce any of them in the proceeding.
A delay or omission by the Trustee or any Securityholder in exercising any right
or remedy accruing upon an Event of Default shall not impair the right or remedy
or constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative.

                  SECTION 6.04. Waiver of Past Defaults. The Holders of a
majority in principal amount of the Securities by notice to the Trustee may
waive an existing Default and its consequences except (i) a Default in the
payment of the principal of or interest on a Security, (ii) a Default arising
from the failure to redeem or purchase any Security when required pursuant to
the terms of this Indenture or (iii) a Default in respect of a provision that
under Section 9.02 cannot be amended without the consent of each Securityholder
affected. When a Default is waived, it is deemed cured, but no such waiver shall
extend to any subsequent or other Default or impair any consequent right.

                  SECTION 6.05. Control by Majority. The Holders of a majority
in principal amount of the Securities may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. However, the Trustee may
refuse to follow any direction that conflicts with law, this Indenture or the
Escrow and Disbursement Agreement or,

<PAGE>   46
                                                                              41


subject to Section 7.01, that the Trustee determines is unduly prejudicial to
the rights of other Securityholders or would involve the Trustee in personal
liability; provided, however, that the Trustee may take any other action deemed
proper by the Trustee that is not inconsistent with such direction. Prior to
taking any action hereunder, the Trustee shall be entitled to indemnification
satisfactory to it in its sole discretion against all losses and expenses caused
by taking or not taking such action.

                  SECTION 6.06. Limitation on Suits. Except to enforce the right
to receive payment of principal, premium (if any) or interest when due, no
Securityholder may pursue any remedy with respect to this Indenture or the
Securities unless:

                  (1) the Holder gives to the Trustee written notice stating
         that an Event of Default is continuing;

                  (2) the Holders of at least 25% in principal amount of the
         Securities make a written request to the Trustee to pursue the remedy;

                  (3) such Holder or Holders offer to the Trustee reasonable
         security or indemnity against any loss, liability or expense;

                  (4) the Trustee does not comply with the request within 60
         days after receipt of the request and the offer of security or
         indemnity; and

                  (5) the Holders of a majority in principal amount of the
         Securities do not give the Trustee a direction inconsistent with the
         request during such 60-day period.

                  A Securityholder may not use this Indenture to prejudice the
rights of another Securityholder or to obtain a preference or priority over
another Securityholder.

                  SECTION 6.07. Rights of Holders to Receive Payment.
Notwithstanding any other provision of this Indenture, the right of any Holder
to receive payment of principal of and liquidated damages and interest on the
Securities held by such Holder, on or after the respective due dates expressed
in the Securities, or to bring suit for the enforcement of any such payment on
or after such respective dates, shall not be impaired or affected without the
consent of such Holder.

                  SECTION 6.08. Collection Suit by Trustee. If an Event of
Default specified in Section 6.01(1) or (2) occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust
against the Company for the whole amount then due and owing (together with
interest on any unpaid interest to the extent lawful) and the amounts provided
for in Section 7.07.

                  SECTION 6.09. Trustee May File Proofs of Claim. The Trustee
may file such proofs of claim and other papers or documents as may be necessary
or advisable in order to have the claims of the Trustee and the Securityholders
allowed in any judicial proceedings relative to the Company, any Subsidiary or
Subsidiary Guarantor, their creditors or their property and, unless prohibited
by law or applicable regulations, may vote on behalf of the Holders in any
election of a trustee in bankruptcy or other Person performing similar
functions, and any Custodian in any such judicial proceeding is hereby
authorized by each Holder to make payments to the Trustee and, in the event that

<PAGE>   47
                                                                              42


the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and its counsel, and any other amounts due the Trustee under Section 7.07.

                  SECTION 6.10. Priorities. If the Trustee collects any money or
property pursuant to this Article 6 or the Escrow and Disbursement Agreement, it
shall pay out the money or property in the following order:

                  FIRST: to the Trustee for amounts due under Section 7.07 and
         to the Escrow Agent pursuant to the Escrow and Disbursement Agreement;

                  SECOND: to Securityholders for amounts due and unpaid on the
         Securities for principal and interest, ratably, and any liquidated
         damages without preference or priority of any kind, according to the
         amounts due and payable on the Securities for principal, any liquidated
         damages and interest, respectively; and

                  THIRD: to the Company provided that all sums due and owing to
         the Holders, the Trustee and the Escrow Agent have been paid in full as
         required by this Indenture.

                  The Trustee may fix a record date and payment date for any
payment to Securityholders pursuant to this Section 6.10. At least 15 days
before such record date, the Trustee shall mail to each Securityholder and the
Company a notice that states the record date, the payment date and amount to be
paid.

                  SECTION 6.11. Undertaking for Costs. In any suit for the
enforcement of any right or remedy under this Indenture or in any suit against
the Trustee for any action taken or omitted by it as Trustee, a court in its
discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including reasonable attorneys' fees, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section 6.11 does not apply
to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit
by Holders of more than 10% in principal amount of the Securities.

                  SECTION 6.12. Waiver of Stay or Extension Laws. Neither the
Company nor any Subsidiary Guarantor which becomes a party to this Indenture (to
the extent it may lawfully do so) shall at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Company (to
the extent that it may lawfully do so) hereby expressly waives, and each
Subsidiary Guarantor which becomes a party to this Indenture (to the extent that
it may lawfully do so) will agree to waive, all benefit or advantage of any such
law, and shall not hinder, delay or impede the execution of any power herein
granted to the Trustee, but shall suffer and permit the execution of every such
power as though no such law had been enacted.

                                    ARTICLE 7

                                     Trustee

                  SECTION 7.01. Duties of Trustee. (a) If an Event of Default
has occurred and is continuing, the Trustee shall exercise the rights and powers
vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent Person would exercise or use under the circumstances
in the conduct of such Person's own affairs.

                  (b)  Except during the continuance of an Event of Default:

                  (1) the Trustee undertakes to perform such duties and only
         such duties as are specifically set forth in this Indenture and the
         Escrow and Disbursement Agreement and no implied covenants or
         obligations shall be read into this Indenture or the Escrow and
         Disbursement Agreement against the Trustee; and

                  (2) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture or the Escrow and Disbursement Agreement. However, the
         Trustee shall examine the certificates and opinions to determine
         whether or not they conform to the requirements of this Indenture or
         the Escrow and Disbursement Agreement.

                  (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own wilful misconduct,
except that:

                  (1) this paragraph does not limit the effect of paragraph (b)
         of this Section 7.01;

                  (2) the Trustee shall not be liable for any error of judgment
         made in good faith by a Trust Officer unless it is proved that the
         Trustee was negligent in ascertaining the pertinent facts; and

                  (3) the Trustee shall not be liable with respect to any action
         it takes or omits to take in good faith in accordance with a direction
         received by it pursuant to Section 6.05.

                  (d) Every provision of this Indenture that in any way relates
to the Trustee is subject to paragraphs (a), (b) and (c) of this Section 7.01.

                  (e) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.

                  (f) Money held in trust by the Trustee need not be segregated
from other funds except to the extent required by law.

                  (g) No provision of this Indenture or the Escrow and
Disbursement Agreement shall require the Trustee to expend or risk its own funds
or otherwise incur financial liability in the performance of any of its duties
hereunder or in the exercise of

<PAGE>   49
                                                                              44


any of its rights or powers, if it shall have reasonable grounds to believe that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

                  (h) Every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section 7.01 and to the provisions of the TIA.

                  SECTION 7.02. Rights of Trustee. Subject to Section 7.01: (a)
The Trustee may rely on any document believed by it to be genuine and to have
been signed or presented by the proper person. The Trustee need not investigate
any fact or matter stated in the document.

                  (b) Before the Trustee acts or refrains from acting, it may
require an Officers' Certificate or an Opinion of Counsel. The Trustee shall not
be liable for any action it takes or omits to take in good faith in reliance on
the Officers' Certificate or Opinion of Counsel.

                  (c) The Trustee may act through agents and shall not be
responsible for the misconduct or negligence of any agent appointed with due
care.

                  (d) The Trustee shall not be liable for any action it takes or
omits to take in good faith which it believes to be authorized or within its
rights or powers; provided, however, that the Trustee's conduct does not
constitute wilful misconduct or negligence.

                  (e) The Trustee may consult with counsel, and the advice or
opinion of counsel with respect to legal matters relating to this Indenture, the
Securities and the Escrow and Disbursement Agreement shall be full and complete
authorization and protection from liability in respect to any action taken,
omitted or suffered by it here under in good faith and in accordance with the
advice or opinion of such counsel.

                  (f) The Trustee shall have no duty to inquire as to the
performance of the covenants in Article 4 hereof, except pursuant to Sections
4.01, 4.09, 4.10 and 4.16. In addition, the Trustee shall not be deemed to have
knowledge of any Default or Event of Default except (i) any Event of Default
occurring pursuant to Sections 6.01(1), 6.01(2), 4.01, 4.09, 4.10 or 4.16 or 
(ii) any Default or Event of Default of which the Trustee shall have received
written notification or obtained actual knowledge.
        
                  (g) The Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond,
debenture, note or other paper or document unless requested in writing to do so
by the Holders of not less than a majority in principal amount of the Securities
at the time outstanding, but the Trustee, in its discretion, may make such
further inquiry or investigation into such facts or matters as it may see fit,
and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises
of the Company, personally or by agent or attorney.

                  SECTION 7.03. Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or its Affiliates with the same rights
it would have if it were not Trustee. Any Paying Agent, Registrar, co-paying
agent or the Escrow Agent

<PAGE>   50
                                                                              45


may do the same with like rights. However, the Trustee must comply with Sections
7.10 and 7.11.

                  SECTION 7.04. Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture, or the Securities or the Escrow and Disbursement Agreement, it
shall not be accountable for the Company's use of the proceeds from the
Securities, and it shall not be responsible for any statement of the Company in
this Indenture or in any document issued in connection with the sale of the
Securities, in the Securities or the Escrow and Disbursement Agreement other
than the Trustee's certificate of authentication.

                  SECTION 7.05. Notice of Defaults. If a Default occurs and is
continuing and if it is known to the Trustee, the Trustee shall mail to each
Securityholder notice of the Default within the earlier of 90 days after it
occurs or 30 days after it is known to a trust officer. Except in the case of a
Default in payment of principal of or interest on any Security (including
payments pursuant to the mandatory redemption provisions of such Security, if
any), or a Default in complying with any provisions of the Escrow and
Disbursement Agreement, the Trustee may withhold the notice if and so long as a
committee of its Trust Officers in good faith determines that withholding the
notice is in the interests of Securityholders.

                  SECTION 7.06. Reports by Trustee to Holders. As promptly as
practicable after each December 31 beginning with the December 31 following the
date of this Indenture, and in any event prior to February 15 in each year, the
Trustee shall mail to each Securityholder a brief report dated as of February 15
that complies with Section 313(a) of the TIA. The Trustee shall also comply with
Section 313(b) of the TIA.

                  A copy of each report at the time of its mailing to
Securityholders shall be filed with the SEC and each stock exchange (if any) on
which the Securities are listed. The Company agrees to notify promptly the
Trustee whenever the Securities become listed on any stock exchange and of any
delisting thereof.

                  SECTION 7.07. Compensation and Indemnity. The Company shall
pay to the Trustee from time to time reasonable compensation for its services.
The Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred or made by it,
including costs of collection, in addition to the compensation for its services.
Such expenses shall include the reasonable compensation and expenses,
disbursements and advances of the Trustee's agents, counsel, accountants and
experts. The Company and each Subsidiary Guarantor that becomes a party to this
Indenture pursuant to Section 4.11, jointly and severally shall indemnify the
Trustee against any and all loss, liability or expense (including reasonable
attorneys' fees) incurred by or in connection with the administration of this
trust and the performance of its their duties hereunder. The Trustee shall
notify the Company of any claim for which it may seek indemnity promptly upon
obtaining actual knowledge thereof; provided, however, that any failure so to
notify the Company shall not relieve the Company or any Subsidiary Guarantor of
its indemnity obligations hereunder. The Company shall defend the claim and the
indemnified party shall provide reasonable cooperation at the Company's expense
in the defense. Such indemnified parties may have separate counsel and the
Company and the Subsidiary Guarantors, as applicable, shall pay the fees and
expenses of such counsel; provided, however, that the Company shall not be
required to

<PAGE>   51

                                                                              46


pay such fees and expenses if it assumes such indemnified parties' defense and,
in such indemnified parties' reasonable judgment, there is no conflict of
interest between the Company and the Subsidiary Guarantors, as applicable, and
such parties in connection with such defense. The Company need not reimburse any
expense or indemnify against any loss, liability or expense incurred by an
indemnified party through such party's own wilful misconduct, negligence or bad
faith.

                  To secure the Company's payment obligations pursuant to this
Section 7.07, the Trustee shall have a lien prior to the Securities on all money
or property held or collected by the Trustee other than money or property held
in trust to pay principal of and interest and any liquidated damages on
particular Securities.

                  The Company's payment obligations pursuant to this Section
shall survive the satisfaction or discharge of this Indenture, any rejection or
termination of this Indenture under any bankruptcy law or the resignation or
removal of the Trustee. When the Trustee incurs expenses after the occurrence of
a Default specified in Section 6.01(7) or (8) with respect to the Company, the
expenses are intended to constitute expenses of administration under the
Bankruptcy Law.

                  SECTION 7.08. Replacement of Trustee. The Trustee may resign
at any time by so notifying the Company. The Holders of a majority in principal
amount of the Securities may remove the Trustee by so notifying the Trustee and
may appoint a successor Trustee. The Company shall remove the Trustee if:

                  (1) the Trustee fails to comply with Section 7.10;

                  (2) the Trustee is adjudged bankrupt or insolvent;

                  (3) a receiver or other public officer takes charge of the
         Trustee or its property; or

                  (4) the Trustee otherwise becomes incapable of acting.

                  If the Trustee resigns, is removed by the Company or by the
Holders of a majority in principal amount of the Securities and such Holders do
not reasonably promptly appoint a successor Trustee, or if a vacancy exists in
the office of Trustee for any reason (the Trustee in such event being referred
to herein as the retiring Trustee), the Company shall promptly appoint a
successor Trustee.

                  A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Securityholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.07.

                  If a successor Trustee does not take office within 60 days
after the retiring Trustee resigns or is removed, the retiring Trustee or the
Holders of 10% in principal amount of the Securities may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

                                                                              47


                  If the Trustee fails to comply with Section 7.10, any
Securityholder may petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor Trustee.

                  Notwithstanding the replacement of the Trustee pursuant to
this Section 7.07, the Company's obligations under Section 7.07 shall continue
for the benefit of the retiring Trustee.

                  SECTION 7.09. Successor Trustee by Merger. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

                  In case at the time such successor or successors by merger,
conversion or consolidation to the Trustee shall succeed to the trusts created
by this Indenture any of the Securities shall have been authenticated but not
delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Securities so
authenticated; and in case at that time any of the Securities shall not have
been authenticated, any successor to the Trustee may authenticate such
Securities either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; and in all such cases such certificates shall have the
full force which it is anywhere in the Securities or in this Indenture provided
that the certificate of the Trustee shall have.

                  SECTION 7.10. Eligibility; Disqualification. The Trustee shall
at all times satisfy the requirements of TIA Section 310(a). The Trustee or the
bank holding company of which the Trustee is a wholly-owned subsidiary shall
have a combined capital and surplus of at least $100,000,000 as set forth in its
most recent published annual report of condition. The Trustee shall comply with
TIA Section 310(b); provided, however, that there shall be excluded from the
operation of TIA Section 310(b)(1) any indenture or indentures under which other
securities or certificates of interest or participation in other securities of
the Company are outstanding if the requirements for such exclusion set forth in
TIA Section 310(b)(1) are met.

                  SECTION 7.11. Preferential Collection of Claims Against
Company. The Trustee shall comply with TIA Section 311(a), excluding any
creditor relationship listed in TIA Section 311(b). A Trustee who has resigned
or been removed shall be subject to TIA Section 311(a) to the extent indicated.

                       Discharge of Indenture; Defeasance

                  SECTION 8.01. Discharge of Liability on Securities;
Defeasance. (a) When (i) the Company delivers to the Trustee all outstanding
Securities (other than Securities replaced pursuant to Section 2.08) for
cancelation or (ii) all outstanding Securities have become due and payable,
whether at maturity or as a result of the mailing of a notice of redemption
pursuant to Article 3 hereof, and the Company irrevocably deposits with the
Trustee funds or U.S. Government Obligations on which payment of principal and
interest when due will be sufficient to pay at maturity or upon redemption

<PAGE>   53

                                                                              48


all outstanding Securities, including interest thereon to maturity or such
redemption date (other than Securities replaced pursuant to Section 2.08), and
if in either case the Company pays all other sums payable hereunder by the
Company, then this Indenture shall, subject to Section 8.01(c), cease to be of
further effect. The Trustee shall acknowledge satisfaction and discharge of this
Indenture on demand of the Company accompanied by an Officers' Certificate and
an Opinion of Counsel and at the cost and expense of the Company.

                  (b) Subject to Sections 8.01(c) and 8.02, the Company at any
time may terminate (i) all of its obligations under the Securities and this
Indenture ("legal defeasance option") or (ii) its obligations under Sections
4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14 and
4.15 and the operation of Section 5.01(a)(iii), 6.01(4), 6.01(6), 6.01(7) (with
respect to Significant Subsidiaries of the Company only), 6.01(8) (with respect
to Significant Subsidiaries of the Company only) and 6.01(9) ("covenant
defeasance option"). The Company may exercise its legal defeasance option
notwithstanding its prior exercise of its covenant defeasance option. In the
event that the Company terminates all of its obligations under the Securities
and this Indenture by exercising its legal defeasance option, the obligations
under the Subsidiary Guarantees, if any, shall each be terminated simultaneously
with the termination of such obligations.

                  If the Company exercises its legal defeasance option, payment
of the Securities may not be accelerated because of an Event of Default. If the
Company exercises its covenant defeasance option, payment of the Securities may
not be accelerated because of an Event of Default specified in Sections 6.01(4),
6.01(6), 6.01(7) (with respect to Significant Subsidiaries of the Company only),
6.01(8) (with respect to Significant Subsidiaries of the Company only) or
6.01(9) or because of the failure of the Company to comply with Section
5.01(a)(iii).

                  Upon satisfaction of the conditions set forth herein and upon
request of the Company, the Trustee shall acknowledge in writing the discharge
of those obligations that the Company terminates.

                  (c) Notwithstanding clauses (a) and (b) above, the Company's
obligations in Sections 2.04, 2.05, 2.06, 2.07, 2.08, 2.09, 7.07, 7.08 and in
this Article 8 shall survive until the Securities have been paid in full.
Thereafter, the Company's obligations in Sections 7.07, 8.04 and 8.05 shall
survive.

                  SECTION 8.02. Conditions to Defeasance. The Company may
exercise its legal defeasance option or its covenant defeasance option only if:

                  (1) the Company irrevocably deposits in trust with the Trustee
         money or U.S. Government Obligations for the payment of principal,
         premium (if any) and interest on the Securities to maturity or
         redemption, as the case may be;

                  (2) the Company delivers to the Trustee a certificate from a
         nationally recognized firm of independent accountants expressing their
         opinion that the payments of principal and interest when due and
         without reinvestment on the deposited U.S. Government Obligations plus
         any deposited money without investment will provide cash at such times
         and in such amounts as will be

                                                                              49


         sufficient to pay principal and interest when due on all the Securities
         to maturity or redemption, as the case may be;

                  (3) 123 days pass after the deposit is made and during the
         123-day period no Default specified in Section 6.01(7) or (8) with
         respect to the Company occurs which is continuing at the end of the
         period;

                  (4) the deposit does not constitute a default under any other
         agreement binding on the Company;

                  (5) the Company delivers to the Trustee an Opinion of Counsel
         to the effect that the trust resulting from the deposit does not
         constitute, or is qualified as, a regulated investment company under
         the Investment Company Act of 1940;

                  (6) in the case of the legal defeasance option, the Company
         shall have delivered to the Trustee an Opinion of Counsel stating that
         (i) the Company has received from, or there has been published by, the
         Internal Revenue Service a ruling, or (ii) since the date of this
         Indenture there has been a change in the applicable Federal income tax
         law, in either case to the effect that, and based thereon such Opinion
         of Counsel shall confirm that, the Securityholders will not recognize
         income, gain or loss for Federal income tax purposes as a result of
         such defeasance and will be subject to Federal income tax on the same
         amounts, in the same manner and at the same times as would have been
         the case if such defeasance had not occurred;

                  (7) in the case of the covenant defeasance option, the Company
         shall have delivered to the Trustee an Opinion of Counsel to the effect
         that the Security holders will not recognize income, gain or loss for
         Federal income tax purposes as a result of such covenant defeasance and
         will be subject to Federal income tax on the same amounts, in the same
         manner and at the same times as would have been the case if such
         covenant defeasance had not occurred; and

                  (8) the Company delivers to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent to the defeasance and discharge of the Securities as
         contemplated by this Article 8 have been complied with.

                  Before or after a deposit, the Company may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date in
accordance with Article 3.

                  SECTION 8.03. Application of Trust Money. The Trustee shall
hold in trust money or U.S. Government Obligations deposited with it pursuant to
this Article 8. It shall apply the deposited money and the money from U.S.
Government Obligations through the Paying Agent and in accordance with this
Indenture to the payment of principal of and interest on the Securities.

                  SECTION 8.04. Repayment to Company. The Trustee and the Paying
Agent shall promptly turn over to the Company upon request any excess money or
securities held by them at any time.

<PAGE>   55
                                                                              50


                  Subject to any applicable abandoned property law, the Trustee
and the Paying Agent shall pay to the Company upon written request any money
held by them for the payment of principal or interest that remains unclaimed for
two years, and, thereafter, Securityholders entitled to the money must look to
the Company for payment as general creditors.

                  SECTION 8.05. Indemnity for Government Obligations. The
Company shall pay and shall indemnify the Trustee against any tax, fee or other
charge imposed on or assessed against deposited U.S. Government Obligations or
the principal and interest received on such U.S. Government Obligations.

                  SECTION 8.06. Reinstatement. If the Trustee or Paying Agent is
unable to apply any money or U.S. Government Obligations in accordance with this
Article 8 by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article 8 until such time as the Trustee
or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with this Article 8; provided, however, that, if the
Company has made any payment of interest on or principal of any Securities
because of the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the
money or U.S. Government Obligations held by the Trustee or Paying Agent.


                                    ARTICLE 9

                                   Amendments

                  SECTION 9.01. Without Consent of Holders. The Company, the
Subsidiary Guarantors, if any, and the Trustee may amend this Indenture or the
Securities without notice to or consent of any Securityholder:

                  (1) to cure any ambiguity, omission, defect or inconsistency;

                  (2) to comply with Article 5;

                  (3) to provide for uncertificated Securities in addition to or
         in place of certificated Securities; provided, however, that the
         uncertificated Securities are issued in registered form for purposes of
         Section 163(f) of the Code or in a manner such that the uncertificated
         Securities are described in Section 163(f)(2)(B) of the Code;

                  (4) to add additional Guarantees with respect to the
         Securities or to secure the Securities or to create and maintain a
         valid first priority security interest in and on the Escrow Collateral
         in favor of the Trustee for the benefit of Holders;

                  (5) to add to the covenants of the Company for the benefit of
         the Holders or to surrender any right or power herein conferred upon
         the Company;

<PAGE>   56
                                                                              51


                  (6) to comply with any requirements of the SEC in connection
         with qualifying, or maintaining the qualification of, this Indenture
         under the TIA;

                  (7) to make any change that does not adversely affect the
         rights of any Securityholder; or

                  (8) to provide for the issuance of the Exchange Securities,
         Private Exchange Securities or Additional Securities, which shall have
         terms substantially identical in all material respects to the Original
         Securities (except that the transfer restrictions contained in the
         Original Securities shall be modified or eliminated, as appropriate),
         and which shall be treated, together with any outstanding Original
         Securities, as a single issue of securities.

                  After an amendment under this Section becomes effective, the
Company shall mail to Securityholders a notice briefly describing such
amendment. The failure to give such notice to all Securityholders, or any defect
therein, shall not impair or affect the validity of an amendment under this
Section.

                  SECTION 9.02. With Consent of Holders. The Company, the
Subsidiary Guarantors, if any, and the Trustee may amend this Indenture or the
Securities without notice to any Securityholder but with the written consent of
the Holders of at least a majority in principal amount of the Securities then
outstanding (including consents obtained in connection with a tender offer or
exchange offer for the Securities). However, without the consent of each
Securityholder affected, an amendment may not:

                  (1) reduce the amount of Securities whose Holders must consent
         to an amendment;

                  (2) reduce the rate of or extend the time for payment of
         interest or any liquidated damages on any Security;

                  (3) reduce the principal of or extend the Stated Maturity of
         any Security;

                  (4) reduce the premium payable upon the redemption of any
         Security or change the time at which any Security may be redeemed in
         accordance with Article 3 or paragraph 5 of the Securities;

                  (5) make any Security payable in money other than that stated
         in the Security;

                  (6) make any change in Section 6.04 or 6.07 or the second
         sentence of this Section 9.02;

                  (7) modify or affect in any manner adverse to the Holders the
         terms and conditions of the obligation of any Subsidiary Guarantor for
         the due and punctual payment of the principal of or any liquidated
         damages or interest on the Securities;

                  (8) impair the right of any Holder to receive payment of
         principal of and interest or any liquidated damages on such Holder's
         Securities on or after the due

<PAGE>   57
                                                                              52


         dates therefor or to institute suit for the enforcement of any payment
         on or with respect to such Holder's Securities; or

                  (9) modify the provisions of the Escrow and Disbursement
         Agreement or this Indenture relating to the Escrow Collateral in any
         manner adverse to the Holders or release any of the Escrow Collateral
         from the Lien under the Escrow and Disbursement Agreement or permit any
         other obligation to be secured by the Escrow Collateral.

                  It shall not be necessary for the consent of the Holders under
this Section 9.02 to approve the particular form of any proposed amendment, but
it shall be sufficient if such consent approves the substance thereof.

                  After an amendment under this Section 9.02 becomes effective,
the Company shall mail to Securityholders a notice briefly describing such
amendment. The failure to give such notice to all Securityholders, or any defect
therein, shall not impair or affect the validity of an amendment under this
Section 9.02.

                  SECTION 9.03. Compliance with Trust Indenture Act. Every
amendment to this Indenture or the Securities shall comply with the TIA as then
in effect.

                  SECTION 9.04. Revocation and Effect of Consents and Waivers. A
consent to an amendment or a waiver by a Holder of a Security shall bind the
Holder and every subsequent Holder of that Security or portion of the Security
that evidences the same debt as the consenting Holder's Security, even if
notation of the consent or waiver is not made on the Security. However, any such
Holder or subsequent Holder may revoke the consent or waiver as to such Holder's
Security or portion of the Security if the Trustee receives the notice of
revocation before the date the amendment or waiver becomes effective. After an
amendment or waiver becomes effective, it shall bind every Securityholder. An
amendment or waiver becomes effective once both (i) the requisite number of
consents have been received by the Company or the Trustee and (ii) such
amendment or waiver has been executed by the Company and the Trustee.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Securityholders entitled to give their
consent or take any other action described above or required or permitted to be
taken pursuant to this Indenture. If a record date is fixed, then
notwithstanding the immediately preceding paragraph, those Persons who were
Securityholders at such record date (or their duly designated proxies), and only
those Persons, shall be entitled to give such consent or to revoke any consent
previously given or to take any such action, whether or not such Persons
continue to be Holders after such record date. No such consent shall be valid or
effective for more than 120 days after such record date.

                  SECTION 9.05. Notation on or Exchange of Securities. If an
amendment changes the terms of a Security, the Trustee may require the Holder of
the Security to deliver it to the Trustee. The Trustee may place an appropriate
notation on the Security regarding the changed terms and return it to the
Holder. Alternatively, if the Company or the Trustee so determines, the Company
in exchange for the Security shall issue and the Trustee shall authenticate a
new Security that reflects the changed terms. Failure to make the appropriate
notation or to issue a new Security shall not affect the validity of such
amendment.

                                                                              53


                  SECTION 9.06. Trustee to Sign Amendments. The Trustee shall
sign any amendment authorized pursuant to this Article 9 if the amendment does
not adversely affect the rights, duties, liabilities or immunities of the
Trustee. If it does, the Trustee may but need not sign it. In signing such
amendment the Trustee shall be entitled to receive indemnity reasonably
satisfactory to it and to receive, and (subject to Section 7.01) shall be fully
protected in relying upon, an Officers' Certificate and an Opinion of Counsel
stating that such amendment is authorized or permitted by this Indenture and
that such amendment is the legal, valid and binding obligation of the Company
and the Subsidiary Guarantors, if any, enforceable against them in accordance
with its terms, subject to customary exceptions, and complies with the
provisions hereof (including Section 9.03).

                  SECTION 9.07. Payment for Consent. Neither the Company nor any
Affiliate of the Company shall, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
for or as an inducement to any consent, waiver or amendment of any of the terms
or provisions of this Indenture or the Securities unless such consideration is
offered to be paid to all Holders that so consent, waive or agree to amend in
the time frame set forth in solicitation documents relating to such consent,
waiver or agreement.


                                   ARTICLE 10

                         Escrow Collateral and Security

                  SECTION 10.01. Escrow and Disbursement Agreement. The due and
punctual payment of the first four semi-annual interest payments on the
Securities, when and as the same shall be due and payable on an Interest Payment
Date or by acceleration, shall be secured as provided in the Escrow and
Disbursement Agreement which the Company, the Escrow Agent and the Trustee have
entered into simultaneously with the execution of this Indenture. Upon
acceleration of the Securities prior to the payment in full of the first four
semi-annual interest payments on the Securities, the Escrow Agent shall, upon
the receipt of written notice from the Trustee, as agent for the Trustee,
foreclose upon the Escrow Collateral. Each Holder of Securities, by its
acceptance thereof, consents and agrees to the terms of the Escrow and
Disbursement Agreement (including, without limitation, the provisions providing
for foreclosure and disbursement of the Escrow Collateral) as the same may be in
effect or may be amended from time to time in accordance with its terms and the
terms hereof and authorizes and directs the Escrow Agent and the Trustee to
enter into the Escrow and Disbursement Agreement and to perform its obligations
and exercise its rights thereunder in accordance therewith. The Company shall
deliver to the Trustee copies of the Escrow and Disbursement Agreement, and
shall do or cause to be done all such acts and things as may be necessary or
proper, or as may be required by the provisions of the Escrow and Disbursement
Agreement, to assure and confirm to the Trustee the security interest in the
Escrow Collateral contemplated by the Escrow and Disbursement Agreement or any
part thereof, as from time to time constituted, so as to render the Escrow
Collateral available for the security and benefit of this Indenture with respect
to the Securities, according to the intent and purposes expressed in the Escrow
and Disbursement Agreement. The Company shall take any and all actions
reasonably required to cause the Escrow and Disbursement Agreement to create and
maintain (to the extent possible under applicable law), as security for the

concurred in any direction, waiver or consent, Securities owned by the Company,
any Subsidiary Guarantor or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company or any
Subsidiary Guarantor shall be disregarded and deemed not to be outstanding,
except that, for the purpose of determining whether the Trustee shall be

foregoing, only Securities outstanding at the time shall be considered in any
such determination.

                                                                   July 24, 1998

CHASE SECURITIES INC.
270 Park Avenue, 4th floor
New York, New York  10017

Ladies and Gentlemen:

                  Splitrock Services, Inc., a Delaware corporation (the
"Company"),proposes to issue and sell to Chase Securities Inc. ("CSI" or the
"Initial Purchaser"), upon the terms and subject to the conditions set forth in
a purchase agreement dated July 21, 1998 (the "Purchase Agreement"), 261,000
units (the "Units"), each Unit consisting of $1,000 principal amount of the
Company's 11 3/4% Senior Notes due 2008 (the "Notes") and one warrant to
purchase 10.124954 shares of common stock, par value $.001 per share, of the
Company. Capitalized terms used but not defined herein shall have the meanings
given to such terms in the Purchase Agreement.

                  As an inducement to the Initial Purchaser to enter into the
Purchase Agreement and in satisfaction of a condition to the obligations of the
Initial Purchaser thereunder, the Company agrees with the Initial Purchaser, for
the benefit of the holders (including the Initial Purchaser) of the Notes, the
Exchange Notes (as defined herein) and the Private Exchange Notes (as defined
herein) (collectively, the "Holders"), as follows:

                  1. Registered Exchange Offer. The Company shall (i) prepare
and, not later than 45 days following the date of original issuance of the Notes
(the "Issue Date"), file with the Commission a registration statement (the
"Exchange Offer Registration Statement") on an appropriate form under the
Securities Act with respect to a proposed offer to the Holders of the Notes (the
"Registered Exchange Offer") to issue and deliver to such Holders, in exchange
for the Notes, a like aggregate principal amount of debt securities of the
Company (the "Exchange Notes") that are identical in all material respects to
the Notes, except for the transfer restrictions relating to the Notes, (ii) use
their reasonable best efforts to cause the Exchange Offer Registration Statement
to become effective under the Securities Act no later than 105 days after the
Issue Date and the Registered Exchange Offer to be consummated no later than 135
days after the Issue Date and (iii) keep the Exchange Offer Registration
Statement effective for not less than 30 days (or longer, if required by
applicable law) after the date on which notice of the Registered Exchange Offer
is mailed to the Holders (such period being called the "Exchange Offer
Registration Period"). The Exchange Notes will be issued under the Indenture or
an indenture (the "Exchange Notes Indenture") between the Company, the
Subsidiary Guarantors, if any, and the Trustee or such other bank or trust
company that is



<PAGE>   2


                                                                               2

reasonably satisfactory to the Initial Purchaser, as trustee (the "Exchange
Notes Trustee"), such indenture to be identical in all material respects to the
Indenture, except for the transfer restrictions relating to the Notes (as
described above).

                  Upon the effectiveness of the Exchange Offer Registration
Statement, the Company shall promptly commence the Registered Exchange Offer, it
being the objective of such Registered Exchange Offer to enable each Holder
electing to exchange Notes for Exchange Notes (assuming that such Holder (a) is
not an affiliate of the Company or an Exchanging Dealer (as defined herein) not
complying with the requirements of the next sentence, (b) is not the Initial
Purchaser holding Notes that have, or that are reasonably likely to have, the
status of an unsold allotment in an initial distribution, (c) acquires the
Exchange Notes in the ordinary course of such Holder's business and (d) has no
arrangements or understandings with any person to participate in the
distribution of the Exchange Notes) and to trade such Exchange Notes from and
after their receipt without any limitations or restrictions under the Securities
Act and without material restrictions under the securities laws of the several
states of the United States. The Company, the Initial Purchaser and each
Exchanging Dealer acknowledge that, pursuant to current interpretations by the
Commission's staff of Section 5 of the Securities Act, each Holder that is a
broker-dealer electing to exchange Notes, acquired for its own account as a
result of market-making activities or other trading activities, for Exchange
Notes (an "Exchanging Dealer"), is required to deliver a prospectus containing
substantially the information set forth in Annex A hereto on the cover, in Annex
B hereto in the "Exchange Offer Procedures" section and the "Purpose of the
Exchange Offer" section and in Annex C hereto in the "Plan of Distribution"
section of such prospectus in connection with a sale of any such Exchange Notes
received by such Exchanging Dealer pursuant to the Registered Exchange Offer.

                  If, prior to the consummation of the Registered Exchange
Offer, any Holder holds any Notes acquired by it that have, or that are
reasonably likely to be determined to have, the status of an unsold allotment in
an initial distribution, or any Holder is not entitled to participate in the
Registered Exchange Offer, the Company shall, upon the request of any such
Holder, simultaneously with the delivery of the Exchange Notes in the Registered
Exchange Offer, issue and deliver to any such Holder, in exchange for the Notes
held by such Holder (the "Private Exchange"), a like aggregate principal amount
of debt securities of the Company (the "Private Exchange Notes") that are
identical in all material respects to the Exchange Notes, except for the
transfer restrictions relating to such Private Exchange Notes. The Private
Exchange Notes will be issued under the same indenture as the Exchange Notes,
and the Company shall use its reasonable best efforts to cause the Private
Exchange Notes to bear the same CUSIP number as the Exchange Notes.

                  In connection with the Registered Exchange Offer, the Company
shall:

                  (a) mail to each Holder a copy of the prospectus forming part
         of the Exchange Offer Registration Statement, together with an
         appropriate letter of transmittal and related documents;

                  (b) keep the Registered Exchange Offer open for not less than
         30 days (or longer, if required by applicable law) after the date on
         which notice of the Registered Exchange Offer is mailed to the Holders;

                                                                               3

                  (c) utilize the services of a depositary for the Registered
         Exchange Offer with an address in the Borough of Manhattan, The City of
         New York;

                  (d) permit Holders to withdraw tendered Notes at any time
         prior to the close of business, New York City time, on the last
         business day on which the Registered Exchange Offer shall remain open;
         and

                  (e) otherwise comply in all respects with all laws that are
         applicable to the Registered Exchange Offer.

                  As soon as practicable after the close of the Registered
Exchange Offer and any Private Exchange, as the case may be, the Company shall:

                  (a) accept for exchange all Notes tendered and not validly
         withdrawn pursuant to the Registered Exchange Offer and the Private
         Exchange;

                  (b) deliver to the Trustee for cancelation all Notes so
         accepted for exchange; and

                  (c) cause the Trustee or the Exchange Notes Trustee, as the
         case may be, promptly to authenticate and deliver to each Holder,
         Exchange Notes or Private Exchange Notes, as the case may be, equal in
         principal amount to the Notes of such Holder so accepted for exchange.

                  The Company shall use its reasonable best efforts to keep the
Exchange Offer Registration Statement effective and to amend and supplement the
prospectus contained therein in order to permit such prospectus to be used by
all persons subject to the prospectus delivery requirements of the Securities
Act for such period of time as such persons must comply with such requirements
in order to resell the Exchange Notes; provided that (i) in the case where such
prospectus and any amendment or supplement thereto must be delivered by an
Exchanging Dealer, such period shall be the lesser of 180 days and the date on
which all Exchanging Dealers have sold all Exchange Notes held by them and (ii)
the Company shall make such prospectus and any amendment or supplement thereto
available to any broker-dealer for use in connection with any resale of any
Exchange Notes for a period of not less than 180 days after the consummation of
the Registered Exchange Offer.

                  The Indenture or the Exchange Notes Indenture, as the case may
be, shall provide that the Notes, the Exchange Notes and the Private Exchange
Notes shall vote and consent together on all matters as one class and that none
of the Notes, the Exchange Notes or the Private Exchange Notes will have the
right to vote or consent as a separate class on any matter.

                  Interest on each Exchange Note and Private Exchange Note
issued pursuant to the Registered Exchange Offer and in the Private Exchange
will accrue from the last interest payment date on which interest was paid on
the Notes surrendered in exchange therefor or, if no interest has been paid on
the Notes, from the Issue Date.

                  Each Holder participating in the Registered Exchange Offer
shall be required to represent to the Company that at the time of the
consummation of the Registered Exchange Offer (i) any Exchange Notes received by
such Holder will be

                                                                               4

acquired in the ordinary course of business, (ii) such Holder will have no
arrangements or understanding with any person to participate in the distribution
of the Notes or the Exchange Notes within the meaning of the Securities Act and
(iii) such Holder is not an affiliate of the Company or, if it is such an
affiliate, such Holder will comply with the registration and prospectus delivery
requirements of the Securities Act to the extent applicable.

                  Notwithstanding any other provisions hereof, the Company will
ensure that (i) any Exchange Offer Registration Statement and any amendment
thereto and any prospectus forming part thereof and any supplement thereto
complies in all material respects with the Securities Act and the rules and
regulations of the Commission thereunder, (ii) any Exchange Offer Registration
Statement and any amendment thereto does not, when it becomes effective, contain
an untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements therein not misleading
and (iii) any prospectus forming part of any Exchange Offer Registration
Statement, and any supplement to such prospectus, does not, as of the
consummation of the Registered Exchange Offer, include an untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

                  2. Shelf Registration. If (i) because of any change in law or
applicable interpretations thereof by the Commission's staff the Company is not
permitted to effect the Registered Exchange Offer as contemplated by Section 1
hereof, or (ii) any Notes validly tendered pursuant to the Registered Exchange
Offer are not exchanged for Exchange Notes within 135 days after the Issue Date,
or (iii) the Initial Purchaser so requests with respect to Notes or Private
Exchange Notes not eligible to be exchanged for Exchange Notes in the Registered
Exchange Offer and held by it following the consummation of the Registered
Exchange Offer, or (iv) any applicable law or interpretations do not permit any
Holder to participate in the Registered Exchange Offer, or (v) any Holder that
participates in the Registered Exchange Offer does not receive freely
transferable Exchange Notes in exchange for tendered Notes, or (vi) the Company
so elects, or (vii) any affiliate of the Company so requests with respect to
Transfer Restricted Notes (as defined) held by it, then the following provisions
shall apply:

                 (a) The Company shall use its reasonable best efforts to file
         as promptly as practicable (but in no event more than 30 days after so
         required or requested pursuant to this Section 2) with the Commission,
         and thereafter shall use its reasonable best efforts to cause to be
         declared effective, a shelf registration statement on an appropriate
         form under the Securities Act relating to the offer and sale of the
         Transfer Restricted Notes (as defined below) by the Holders thereof
         from time to time in accordance with the methods of distribution set
         forth in such registration statement (hereafter, a "Shelf Registration
         Statement" and, together with any Exchange Offer Registration
         Statement, a "Registration Statement").

                 (b) The Company shall use its reasonable best efforts to keep
         the Shelf Registration Statement continuously effective in order to
         permit the prospectus forming part thereof to be used by Holders of
         Transfer Restricted Notes for a period ending on the earlier of (i) two
         years from the Issue Date or such shorter period that will terminate
         when all the Transfer Restricted Notes covered by the Shelf
         Registration Statement have been sold pursuant thereto and (ii) the
         date on which the Notes become eligible for resale without volume
         restrictions pursuant




<PAGE>   5


                                                                               5

         to Rule 144 under the Securities Act (in any such case, such period
         being called the "Shelf Registration Period"). The Company shall be
         deemed not to have used its reasonable best efforts to keep the Shelf
         Registration Statement effective during the requisite period if it
         voluntarily takes any action that would result in Holders of Transfer
         Restricted Notes covered thereby not being able to offer and sell such
         Transfer Restricted Notes during that period, unless such action is
         required by applicable law.

                 (c) Notwithstanding any other provisions hereof, the Company
         will ensure that (i) any Shelf Registration Statement and any amendment
         thereto and any prospectus forming part thereof and any supplement
         thereto complies in all material respects with the Securities Act and
         the rules and regulations of the Commission thereunder, (ii) any Shelf
         Registration Statement and any amendment thereto (in either case, other
         than with respect to information included therein in reliance upon or
         in conformity with written information furnished to the Company by or
         on behalf of any Holder specifically for use therein (the "Holders'
         Information")) does not contain an untrue statement of a material fact
         or omit to state a material fact required to be stated therein or
         necessary to make the statements therein not misleading and (iii) any
         prospectus forming part of any Shelf Registration Statement, and any
         supplement to such prospectus (in either case, other than with respect
         to Holders' Information), does not include an untrue statement of a
         material fact or omit to state a material fact necessary in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading.

                  3. Liquidated Damages. (a) The parties hereto agree that the
Holders of Transfer Restricted Notes will suffer damages if the Company fails to
fulfill its obligations under Section 1 or Section 2, as applicable, and that it
would not be feasible to ascertain the extent of such damages. Accordingly, if
(i) the applicable Registration Statement is not filed with the Commission on or
prior to 45 days after the Issue Date, (ii) the Exchange Offer Registration
Statement or the Shelf Registration Statement, as the case may be, is not
declared effective within 105 days after the Issue Date (or in the case of a
Shelf Registration Statement required to be filed in response to a change in law
or the applicable interpretations of Commission's staff, if later, within 45
days after publication of the change in law or interpretation), (iii) the
Registered Exchange Offer is not consummated on or prior to 135 days after the
Issue Date, or (iv) the Shelf Registration Statement is filed and declared
effective within 135 days after the Issue Date (or in the case of a Shelf
Registration Statement required to be filed in response to a change in law or
the applicable interpretations of Commission's staff, if later, within 45 days
after publication of the change in law or interpretation) but shall thereafter
cease to be effective (at any time that the Company is obligated to maintain the
effectiveness thereof) without being succeeded within 30 days by an additional
Registration Statement filed and declared effective (each such event referred to
in clauses (i) through (iv), a "Registration Default"), the Company will be
obligated to pay liquidated damages to each Holder of Transfer Restricted Notes,
during the period of one or more such Registration Defaults, in an amount equal
to $ 0.192 per week per $1,000 principal amount of Transfer Restricted Notes
held by such Holder until (i) the applicable Registration Statement is filed,
(ii) the Exchange Offer Registration Statement is declared effective and the
Registered Exchange Offer is consummated, (iii) the Shelf Registration Statement
is declared effective or (iv) the Shelf Registration Statement again becomes
effective, as the case may be. Following the cure of all Registration Defaults,
the accrual of liquidated damages will cease. As

                                                                               6

used herein, the term "Transfer Restricted Notes" means (i) each Note until the
date on which such Note has been exchanged for a freely transferable Exchange
Note in the Registered Exchange Offer, (ii) each Note or Private Exchange Note
until the date on which it has been effectively registered under the Securities
Act and disposed of in accordance with the Shelf Registration Statement or (iii)
each Note or Private Exchange Note until the date on which it is distributed to
the public pursuant to Rule 144 under the Securities Act or is saleable pursuant
to Rule 144(k) under the Securities Act. Notwithstanding anything to the
contrary in this Section 3(a), the Company shall not be required to pay
liquidated damages to a Holder of Transfer Restricted Notes if such Holder
failed to comply with its obligations to make the representations set forth in
the second to last paragraph of Section 1 or failed to provide the information
required to be provided by it, if any, pursuant to Section 4(n).

                 (b) The Company shall notify the Trustee and the Paying Agent
under the Indenture immediately upon the happening of each and every
Registration Default. The Company shall pay the liquidated damages due on the
Transfer Restricted Notes by depositing with the Paying Agent (which may not be
the Company for these purposes), in trust, for the benefit of the Holders
thereof, prior to 10:00 a.m., New York City time, on the next interest payment
date specified by the Indenture and the Notes, sums sufficient to pay the
liquidated damages then due. The liquidated damages due shall be payable on each
interest payment date specified by the Indenture and the Notes to the record
holder entitled to receive the interest payment to be made on such date. Each
obligation to pay liquidated damages shall be deemed to accrue from and
including the date of the applicable Registration Default.

                 (c) The parties hereto agree that the liquidated damages
provided for in this Section 3 constitute a reasonable estimate of and are
intended to constitute the sole damages that will be suffered by Holders of
Transfer Restricted Notes by reason of the failure of (i) the Shelf Registration
Statement or the Exchange Offer Registration Statement to be filed, (ii) the
Shelf Registration Statement to remain effective or (iii) the Exchange Offer
Registration Statement to be declared effective and the Registered Exchange
Offer to be consummated, in each case to the extent required by this Agreement.

                  4. Registration Procedures. In connection with any
Registration Statement, the following provisions shall apply:

                 (a) The Company shall (i) furnish to the Initial Purchaser,
         prior to the filing thereof with the Commission, a copy of the
         Registration Statement and each amendment thereof and each supplement,
         if any, to the prospectus included therein and shall use its reasonable
         best efforts to reflect in each such document, when so filed with the
         Commission, such comments as the Initial Purchaser may reasonably
         propose; (ii) include the information set forth in Annex A hereto on
         the cover, in Annex B hereto in the "Exchange Offer Procedures" section
         and the "Purpose of the Exchange Offer" section and in Annex C hereto
         in the "Plan of Distribution" section of the prospectus forming a part
         of the Exchange Offer Registration Statement, and include the
         information set forth in Annex D hereto in the Letter of Transmittal
         delivered pursuant to the Registered Exchange Offer; and (iii) if
         requested by any Initial Purchaser, include the information required by
         Items 507 or 508 of Regulation S-K, as applicable, in the prospectus
         forming a part of the Exchange Offer Registration Statement.

                 (b) The Company shall advise the Initial Purchaser, each
         Exchanging Dealer and the Holders (if applicable) and, if requested by
         any such person, confirm such advice in writing (which advice pursuant
         to clauses (ii)-(v) hereof shall be accompanied by an instruction to
         suspend the use of the prospectus until the requisite changes have been
         made):

                            (i) when any Registration Statement and any
                  amendment thereto has been filed with the Commission and when
                  such Registration Statement or any post-effective amendment
                  thereto has become effective;

                            (ii) of any request by the Commission for amendments
                  or supplements to any Registration Statement or the prospectus
                  included therein or for additional information;

                            (iii) of the issuance by the Commission of any stop
                  order suspending the effectiveness of any Registration
                  Statement or the initiation of any proceedings for that
                  purpose;

                            (iv) of the receipt by the Company of any
                  notification with respect to the suspension of the
                  qualification of the Notes, the Exchange Notes or the Private
                  Exchange Notes for sale in any jurisdiction or the initiation
                  or threatening of any proceeding for such purpose; and

                            (v) of the happening of any event that requires the
                  making of any changes in any Registration Statement or the
                  prospectus included therein in order that the statements
                  therein are not misleading and do not omit to state a material
                  fact required to be stated therein or necessary to make the
                  statements therein not misleading.

                 (c) The Company will make every reasonable effort to obtain the
         withdrawal at the earliest possible time of any order suspending the
         effectiveness of any Registration Statement.

                 (d) The Company will furnish to each Holder of Transfer
         Restricted Notes included within the coverage of any Shelf Registration
         Statement, without charge, at least one conformed copy of such Shelf
         Registration Statement and any post-effective amendment thereto,
         including financial statements and schedules and, if any such Holder so
         requests in writing, all exhibits thereto (including those, if any,
         incorporated by reference).

                 (e) The Company will, during the Shelf Registration Period,
         promptly deliver to each Holder of Transfer Restricted Notes included
         within the coverage of any Shelf Registration Statement, without
         charge, as many copies of the prospectus (including each preliminary
         prospectus) included in such Shelf Registration Statement and any
         amendment or supplement thereto as such Holder may reasonably request;
         and the Company consents to the use of such prospectus or any amendment
         or supplement thereto by each of the selling Holders of Transfer
         Restricted Notes in connection with the offer and sale of the Transfer
         Restricted Notes covered by such prospectus or any amendment or
         supplement thereto.

                 (f) The Company will furnish to the Initial Purchaser and each
         Exchanging Dealer, and to any other Holder who so requests, without
         charge, at least one conformed copy of the Exchange Offer Registration
         Statement and any post-effective amendment thereto, including financial
         statements and schedules and, if the Initial Purchaser or Exchanging
         Dealer or any such Holder so requests in writing, all exhibits thereto
         (including those, if any, incorporated by reference).

                 (g) The Company will, during the Exchange Offer Registration
         Period or the Shelf Registration Period, as applicable, promptly
         deliver to the Initial Purchaser, each Exchanging Dealer and such other
         persons that are required to deliver a prospectus following the
         Registered Exchange Offer, without charge, as many copies of the final
         prospectus included in the Exchange Offer Registration Statement or the
         Shelf Registration Statement and any amendment or supplement thereto as
         the Initial Purchaser, such Exchanging Dealer or other persons may
         reasonably request; and the Company consents to the use of such
         prospectus or any amendment or supplement thereto by the Initial
         Purchaser, such Exchanging Dealer or other persons, as applicable, as
         aforesaid.

                 (h) Prior to the effective date of any Registration Statement,
         the Company will use its reasonable best efforts to register or
         qualify, or cooperate with the Holders of Notes, Exchange Notes or
         Private Exchange Notes included therein and their respective counsel in
         connection with the registration or qualification of, such Notes,
         Exchange Notes or Private Exchange Notes for offer and sale under the
         securities or blue sky laws of such jurisdictions as any such Holder
         reasonably requests in writing and do any and all other acts or things
         necessary or advisable to enable the offer and sale in such
         jurisdictions of the Notes, Exchange Notes or Private Exchange Notes
         covered by such Registration Statement; provided that the Company will
         not be required to qualify generally to do business in any jurisdiction
         where it is not then so qualified or to take any action which would
         subject it to general service of process or to taxation in any such
         jurisdiction where it is not then so subject.

                 (i) The Company will cooperate with the Holders of Notes,
         Exchange Notes or Private Exchange Notes to facilitate the timely
         preparation and delivery of certificates representing Notes, Exchange
         Notes or Private Exchange Notes to be sold pursuant to any Registration
         Statement free of any restrictive legends and in such denominations and
         registered in such names as the Holders thereof may request in writing
         prior to sales of Notes, Exchange Notes or Private Exchange Notes
         pursuant to such Registration Statement.

                 (j) If any event contemplated by Section 4(b)(ii) through (v)
         occurs during the period for which the Company is required to maintain
         an effective Registration Statement, the Company will promptly prepare
         and file with the Commission a post-effective amendment to the
         Registration Statement or a supplement to the related prospectus or
         file any other required document so that, as thereafter delivered to
         purchasers of the Notes, Exchange Notes or Private Exchange Notes from
         a Holder, the prospectus will not include an untrue statement of a
         material fact or omit to state a material fact necessary in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading.

                                                                               9

                 (k) Not later than the effective date of the applicable
         Registration Statement, the Company will provide a CUSIP number for the
         Notes, the Exchange Notes and the Private Exchange Notes, as the case
         may be, and provide the applicable trustee with printed certificates
         for the Notes, the Exchange Notes or the Private Exchange Notes, as the
         case may be, in a form eligible for deposit with The Depository Trust
         Company.

                 (l) The Company will comply with all applicable rules and
         regulations of the Commission and the Company will make generally
         available to its security holders as soon as practicable after the
         effective date of the applicable Registration Statement an earning
         statement satisfying the provisions of Section 11(a) of the Securities
         Act; provided that in no event shall such earning statement be
         delivered later than 45 days after the end of a 12-month period (or 90
         days, if such period is a fiscal year) beginning with the first month
         of the Company's first fiscal quarter commencing after the effective
         date of the applicable Registration Statement, which statement shall
         cover such 12-month period.

                 (m) The Company will cause the Indenture or the Exchange Notes
         Indenture, as the case may be, to be qualified under the Trust
         Indenture Act as required by applicable law in a timely manner.

                 (n) The Company may require each Holder of Transfer Restricted
         Notes to be registered pursuant to any Shelf Registration Statement to
         furnish to the Company such information concerning the Holder and the
         distribution of such Transfer Restricted Notes as the Company may from
         time to time reasonably require for inclusion in such Shelf
         Registration Statement, and the Company may exclude from such
         registration the Transfer Restricted Notes of any Holder that fails to
         furnish such information within a reasonable time after receiving such
         request.

                 (o) In the case of a Shelf Registration Statement, each Holder
         of Transfer Restricted Notes to be registered pursuant thereto agrees
         by acquisition of such Transfer Restricted Notes that, upon receipt of
         any notice from the Company pursuant to Section 4(b)(ii) through (v),
         such Holder will discontinue disposition of such Transfer Restricted
         Notes until such Holder's receipt of copies of the supplemental or
         amended prospectus contemplated by Section 4(j) or until advised in
         writing (the "Advice") by the Company that the use of the applicable
         prospectus may be resumed. If the Company shall give any notice under
         Section 4(b)(ii) through (v) during the period that the Company is
         required to maintain an effective Registration Statement (the
         "Effectiveness Period"), such Effectiveness Period shall be extended by
         the number of days during such period from and including the date of
         the giving of such notice to and including the date when each seller of
         Transfer Restricted Notes covered by such Registration Statement shall
         have received (x) the copies of the supplemental or amended prospectus
         contemplated by Section 4(j) (if an amended or supplemental prospectus
         is required) or (y) the Advice (if no amended or supplemental
         prospectus is required).

                 (p) In the case of a Shelf Registration Statement, the Company
         shall enter into such customary agreements (including, if requested, an
         underwriting agreement in customary form) and take all such other
         action, if any, as Holders of



<PAGE>   10

                                                                              10

         a majority in aggregate principal amount of the Notes, Exchange Notes
         and Private Exchange Notes being sold or the managing underwriters (if
         any) shall reasonably request in order to facilitate any disposition of
         Notes, Exchange Notes or Private Exchange Notes pursuant to such Shelf
         Registration Statement.

                 (q) In the case of a Shelf Registration Statement, the Company
         shall (i) make reasonably available for inspection by a representative
         of, and Special Counsel (as defined below) acting for, Holders of a
         majority in aggregate principal amount of the Notes, Exchange Notes and
         Private Exchange Notes being sold and any underwriter participating in
         any disposition of Notes, Exchange Notes or Private Exchange Notes
         pursuant to such Shelf Registration Statement, all relevant financial
         and other records, pertinent corporate documents and properties of the
         Company and (ii) use its reasonable best efforts to have its officers,
         directors, employees, accountants and counsel supply all relevant
         information reasonably requested by such representative, Special
         Counsel or any such underwriter (an "Inspector") in connection with
         such Shelf Registration Statement.

                 (r) In the case of a Shelf Registration Statement, the Company
         shall, if requested by Holders of a majority in aggregate principal
         amount of the Notes, Exchange Notes and Private Exchange Notes being
         sold, their Special Counsel or the managing underwriters (if any) in
         connection with such Shelf Registration Statement, use its reasonable
         best efforts to cause (i) its counsel to deliver an opinion relating to
         the Shelf Registration Statement and the Notes, Exchange Notes or
         Private Exchange Notes, as applicable, in customary form, (ii) its
         officers to execute and deliver all customary documents and
         certificates requested by Holders of a majority in aggregate principal
         amount of the Notes, Exchange Notes and Private Exchange Notes being
         sold, their Special Counsel or the managing underwriters (if any) and
         (iii) its independent public accountants to provide a comfort letter or
         letters in customary form, subject to receipt of appropriate
         documentation as contemplated, and only if permitted, by Statement of
         Auditing Standards No. 72.

                  5. Registration Expenses. The Company will bear all expenses
incurred in connection with the performance of its obligations under Sections 1,
2, 3 and 4 and the Company will reimburse the Initial Purchaser and the Holders
for the reasonable fees and disbursements of one firm of attorneys (in addition
to any local counsel) chosen by the Holders of a majority in aggregate principal
amount of the Notes, the Exchange Notes and the Private Exchange Notes to be
sold pursuant to each Registration Statement (the "Special Counsel") acting for
the Initial Purchaser or Holders in connection therewith.

                  6. Indemnification. (a) In the event of a Shelf Registration
Statement or in connection with any prospectus delivery pursuant to an Exchange
Offer Registration Statement by the Initial Purchaser or Exchanging Dealer, as
applicable, the Company shall indemnify and hold harmless each Holder
(including, without limitation, the Initial Purchaser or such Exchanging
Dealer), its affiliates, their respective officers, directors, employees,
representatives and agents, and each person, if any, who controls such Holder
within the meaning of the Securities Act or the Exchange Act (collectively
referred to for purposes of this Section 6 and Section 7 as a Holder) from and
against any loss, claim, damage or liability, joint or several, or any action in
respect thereof (including, without limitation, any loss, claim, damage,
liability or action relating to purchases and sales of

                                                                              11

Notes, Exchange Notes or Private Exchange Notes), to which that Holder may
become subject, whether commenced or threatened, under the Securities Act, the
Exchange Act, any other federal or state statutory law or regulation, at common
law or otherwise, insofar as such loss, claim, damage, liability or action
arises out of, or is based upon, (i) any untrue statement or alleged untrue
statement of a material fact contained in any such Registration Statement or any
prospectus forming part thereof or in any amendment or supplement thereto or
(ii) the omission or alleged omission to state therein a material fact required
to be stated therein or necessary in order to make the statements therein, in
the light of the circumstances under which they were made, not misleading, and
shall reimburse each Holder promptly upon demand for any legal or other expenses
reasonably incurred by that Holder in connection with investigating or defending
or preparing to defend against or appearing as a third party witness in
connection with any such loss, claim, damage, liability or action as such
expenses are incurred; provided, however, that the Company shall not be liable
in any such case to the extent that any such loss, claim, damage, liability or
action arises out of, or is based upon, an untrue statement or alleged untrue
statement in or omission or alleged omission from any of such documents in
reliance upon and in conformity with any Holders' Information; and provided,
further, that with respect to any such untrue statement in or omission from any
related preliminary prospectus, the indemnity agreement contained in this
Section 6(a) shall not inure to the benefit of any Holder from whom the person
asserting any such loss, claim, damage, liability or action received Notes,
Exchange Notes or Private Exchange Notes to the extent that such loss, claim,
damage, liability or action of or with respect to such Holder results from the
fact that both (A) a copy of the final prospectus was not sent or given to such
person at or prior to the written confirmation of the sale of such Notes,
Exchange Notes or Private Exchange Notes to such person and (B) the untrue
statement in or omission from the related preliminary prospectus was corrected
in the final prospectus unless, in either case, such failure to deliver the
final prospectus was a result of non-compliance by the Company with Section
4(d), 4(e), 4(f) or 4(g).

                 (b) In the event of a Shelf Registration Statement, each Holder
shall indemnify and hold harmless the Company, its affiliates, their respective
officers, directors, employees, representatives and agents, and each person, if
any, who controls the Company within the meaning of the Securities Act or the
Exchange Act (collectively referred to for purposes of this Section 6(b) and
Section 7 as the Company), from and against any loss, claim, damage or
liability, joint or several, or any action in respect thereof, to which the
Company may become subject, whether commenced or threatened, under the
Securities Act, the Exchange Act, any other federal or state statutory law or
regulation, at common law or otherwise, insofar as such loss, claim, damage,
liability or action arises out of, or is based upon, (i) any untrue statement or
alleged untrue statement of a material fact contained in any such Registration
Statement or any prospectus forming part thereof or in any amendment or
supplement thereto or (ii) the omission or alleged omission to state therein a
material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, but in each case only to the extent that the untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with any Holders' Information furnished to
the Company by such Holder, and shall reimburse the Company for any legal or
other expenses reasonably incurred by the Company in connection with
investigating or defending or preparing to defend against or appearing as a
third party witness in connection with any such loss, claim, damage, liability
or action as such expenses are incurred; provided, however, that no such Holder
shall be liable for any indemnity claims hereunder in excess of the amount of
net

                                                                              12

proceeds received by such Holder from the sale of Notes, Exchange Notes or
Private Exchange Notes pursuant to such Shelf Registration Statement.

                 (c) Promptly after receipt by an indemnified party under this
Section 6 of notice of any claim or the commencement of any action, the
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party pursuant to Section 6(a) or 6(b), notify the indemnifying
party in writing of the claim or the commencement of that action; provided,
however, that the failure to notify the indemnifying party shall not relieve it
from any liability which it may have under this Section 6 except to the extent
that it has been materially prejudiced (through the forfeiture of substantive
rights or defenses) by such failure; and provided, further, that the failure to
notify the indemnifying party shall not relieve it from any liability which it
may have to an indemnified party otherwise than under this Section 6. If any
such claim or action shall be brought against an indemnified party, and it shall
notify the indemnifying party thereof, the indemnifying party shall be entitled
to participate therein and, to the extent that it wishes, jointly with any other
similarly notified indemnifying party, to assume the defense thereof with
counsel reasonably satisfactory to the indemnified party. After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 6 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than the reasonable costs of investigation; provided, however,
that an indemnified party shall have the right to employ its own counsel in any
such action, but the fees, expenses and other charges of such counsel for the
indemnified party will be at the expense of such indemnified party unless (1)
the employment of counsel by the indemnified party has been authorized in
writing by the indemnifying party, (2) the indemnified party has reasonably
concluded (based upon advice of counsel to the indemnified party) that there may
be legal defenses available to it or other indemnified parties that are
different from or in addition to those available to the indemnifying party, (3)
a conflict or potential conflict exists (based upon advice of counsel to the
indemnified party) between the indemnified party and the indemnifying party (in
which case the indemnifying party will not have the right to direct the defense
of such action on behalf of the indemnified party) or (4) the indemnifying party
has not in fact employed counsel reasonably satisfactory to the indemnified
party to assume the defense of such action within a reasonable time after
receiving notice of the commencement of the action, in each of which cases the
reasonable fees, disbursements and other charges of counsel will be at the
expense of the indemnifying party or parties. It is understood that the
indemnifying party or parties shall not, in connection with any proceeding or
related proceedings in the same jurisdiction, be liable for the reasonable fees,
disbursements and other charges of more than one separate firm of attorneys (in
addition to any local counsel) at any one time for all such indemnified party or
parties. Each indemnified party, as a condition of the indemnity agreements
contained in Sections 6(a) and 6(b), shall use all reasonable efforts to
cooperate with the indemnifying party in the defense of any such action or
claim. No indemnifying party shall be liable for any settlement of any such
action effected without its written consent (which consent shall not be
unreasonably withheld), but if settled with its written consent or if there be a
final judgment for the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss or liability by reason of such settlement or judgment. No indemnifying
party shall, without the prior written consent of the indemnified party (which
consent shall not be unreasonably withheld), effect any settlement of any
pending or threatened proceeding in respect of which any indemnified party is or
could have been



<PAGE>   13


                                                                              13

a party and indemnity could have been sought hereunder by such indemnified
party, unless such settlement includes an unconditional release of such
indemnified party from all liability on claims that are the subject matter of
such proceeding.

                  7. Contribution. If the indemnification provided for in
Section 6 is unavailable or insufficient to hold harmless an indemnified party
under Section 6(a) or 6(b), then each indemnifying party shall, in lieu of
indemnifying such indemnified party, contribute to the amount paid or payable by
such indemnified party as a result of such loss, claim, damage or liability, or
action in respect thereof, (i) in such proportion as shall be appropriate to
reflect the relative benefits received by the Company from the offering and sale
of the Notes, on the one hand, and a Holder with respect to the sale by such
Holder of Notes, Exchange Notes or Private Exchange Notes, on the other, or (ii)
if the allocation provided by clause (i) above is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause (i) above but also the relative fault of the
Company, on the one hand, and such Holder, on the other, with respect to the
statements or omissions that resulted in such loss, claim, damage or liability,
or action in respect thereof, as well as any other relevant equitable
considerations. The relative benefits received by the Company, on the one hand,
and a Holder, on the other, with respect to such offering and such sale shall be
deemed to be in the same proportion as the total net proceeds from the offering
of the Notes (before deducting expenses) received by or on behalf of the Company
as set forth in the table on the cover of the Offering Memorandum, on the one
hand, bear to the total proceeds received by such Holder with respect to its
sale of Notes, Exchange Notes or Private Exchange Notes, on the other. The
relative fault 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 the Company or information
supplied by the Company, on the one hand, or to any Holders' Information
supplied by such Holder, on the other, the intent of the parties and their
relative knowledge, access to information and opportunity to correct or prevent
such untrue statement or omission. The parties hereto agree that it would not be
just and equitable if contributions pursuant to this Section 7 were to be
determined by pro rata allocation or by any other method of allocation that does
not take into account the equitable considerations referred to herein. The
amount paid or payable by an indemnified party as a result of the loss, claim,
damage or liability, or action in respect thereof, referred to above in this
Section 7 shall be deemed to include, for purposes of this Section 7, any legal
or other expenses reasonably incurred by such indemnified party in connection
with investigating or defending or preparing to defend any such action or claim.
Notwithstanding the provisions of this Section 7, an indemnifying party that is
a Holder of Notes, Exchange Notes or Private Exchange Notes shall not be
required to contribute any amount in excess of the amount by which the total
price at which the Notes, Exchange Notes or Private Exchange Notes sold by such
indemnifying party to any purchaser exceeds the amount of any damages which such
indemnifying party has otherwise paid or become liable to pay by reason of any
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 be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation.

                  8. Rules 144 and 144A. The Company shall use its reasonable
best efforts to file the reports required to be filed by it under the Securities
Act and the Exchange Act in a timely manner and, if at any time the Company is
not required to file


<PAGE>   14


                                                                              14

such reports, it will, upon the written request of any Holder of Transfer
Restricted Notes, make publicly available other information so long as necessary
to permit sales of such Holder's securities pursuant to Rules 144 and 144A. The
Company covenants that it will take such further action as any Holder of
Transfer Restricted Notes may reasonably request, all to the extent required
from time to time to enable such Holder to sell Transfer Restricted Notes
without registration under the Securities Act within the limitation of the
exemptions provided by Rules 144 and 144A (including, without limitation, the
requirements of Rule 144A(d)(4)). Upon the written request of any Holder of
Transfer Restricted Notes, the Company shall deliver to such Holder a written
statement as to whether it has complied with such requirements. Notwithstanding
the foregoing, nothing in this Section 8 shall be deemed to require the Company
to register any of its securities pursuant to the Exchange Act.

                  9. Underwritten Registrations. If any of the Transfer
Restricted Notes covered by any Shelf Registration Statement are to be sold in
an underwritten offering, the investment banker or investment bankers and
manager or managers that will administer the offering will be selected by the
Holders of a majority in aggregate principal amount of such Transfer Restricted
Notes included in such offering, subject to the consent of the Company (which
shall not be unreasonably withheld or delayed), and such Holders shall be
responsible for all underwriting commissions and discounts in connection
therewith.

                  No person may participate in any underwritten registration
hereunder unless such person (i) agrees to sell such person's Transfer
Restricted Notes on the basis reasonably provided in any underwriting
arrangements approved by the persons entitled hereunder to approve such
arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements.

                 10. Miscellaneous. (a) Amendments and Waivers. The provisions
of this Agreement may not be amended, modified or supplemented, and waivers or
consents to departures from the provisions hereof may not be given, unless the
Company has obtained the written consent of Holders of a majority in aggregate
principal amount of the Notes, the Exchange Notes and the Private Exchange
Notes, taken as a single class. Notwithstanding the foregoing, a waiver or
consent to depart from the provisions hereof with respect to a matter that
relates exclusively to the rights of Holders whose Notes, Exchange Notes or
Private Exchange Notes are being sold pursuant to a Registration Statement and
that does not directly or indirectly affect the rights of other Holders may be
given by Holders of a majority in aggregate principal amount of the Notes, the
Exchange Notes and the Private Exchange Notes being sold by such Holders
pursuant to such Registration Statement.

                     (b) Notices. All notices and other communications provided
for or permitted hereunder shall be made in writing by hand-delivery,
first-class mail, telecopier or air courier guaranteeing next-day delivery:

                     (1) if to a Holder, at the most current address given by
         such Holder to the Company in accordance with the provisions of this
         Section 10(b), which address initially is, with respect to each Holder,
         the address of such Holder maintained by the Registrar under the
         Indenture, with a copy in like manner to Chase Securities Inc.;




<PAGE>   15


                                                                              15


                     (2) if to the Initial Purchaser, initially at its address
         set forth in the Purchase Agreement; and

                     (3) if to the Company, initially at the address of the
         Company set forth in the Purchase Agreement.

                  All such notices and communications shall be deemed to have
been duly given: when delivered by hand, if personally delivered; one business
day after being delivered to a next-day air courier; five business days after
being deposited in the mail; and when receipt is acknowledged by the recipient's
telecopier machine, if sent by telecopier.

                 (c) Successors And Assigns. This Agreement shall be binding
upon the Company and its successors and assigns.

                 (d) Counterparts. This Agreement may be executed in any number
of counterparts (which may be delivered in original form or by telecopier) and
by the parties hereto in separate counterparts, each of which when so executed
shall be deemed to be an original and all of which taken together shall
constitute one and the same agreement.

                 (e) Definition of Terms. For purposes of this Agreement, (a)
the term "business day" means any day on which the New York Stock Exchange, Inc.
is open for trading, (b) the term "subsidiary" has the meaning set forth in Rule
405 under the Securities Act and (c) except where otherwise expressly provided,
the term "affiliate" has the meaning set forth in Rule 405 under the Securities
Act.

                  (f) Headings. The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.

                  (g) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

                 (h) Remedies. In the event of a breach by the Company or by any
Holder of any of their obligations under this Agreement, each Holder or the
Company, as the case may be, in addition to being entitled to exercise all
rights granted by law, including recovery of damages (other than the recovery of
damages for a breach by the Company of its obligations under Sections 1 or 2
hereof for which liquidated damages have been paid pursuant to Section 3
hereof), will be entitled to specific performance of its rights under this
Agreement. The Company and each Holder agree that monetary damages would not be
adequate compensation for any loss incurred by reason of a breach by each such
person of any of the provisions of this Agreement and hereby further agree that,
in the event of any action for specific performance in respect of such breach,
each such person shall waive the defense that a remedy at law would be adequate.

                 (i) No Inconsistent Agreements. The Company represents,
warrants and agrees that (i) it has not entered into, shall not, on or after the
date of this Agreement, enter into any agreement that is inconsistent with the
rights granted to the Holders in this Agreement or otherwise conflicts with the
provisions hereof, (ii) it has not previously entered into any agreement which
remains in effect granting any registration rights with respect to any of its
debt securities to any person and (iii) (with respect to the Company)



<PAGE>   16


                                                                              16

without limiting the generality of the foregoing, without the written consent of
the Holders of a majority in aggregate principal amount of the then outstanding
Transfer Restricted Notes, it shall not grant to any person the right to request
the Company to register any debt securities of the Company under the Securities
Act unless the rights so granted are not in conflict or inconsistent with the
provisions of this Agreement.

                 (j) No Piggyback on Registrations. Neither the Company nor any
of its security holders (other than the Holders of Transfer Restricted Notes in
such capacity) shall have the right to include any securities of the Company in
any Shelf Registration or Registered Exchange Offer other than Transfer
Restricted Notes.

                 (k) Severability. The remedies provided herein are cumulative
and not exclusive of any remedies provided by law. If any term, provision,
covenant or restriction of this Agreement is held by a court of competent
jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions set forth herein shall remain in
full force and effect and shall in no way be affected, impaired or invalidated,
and the parties hereto shall use their reasonable best efforts to find and
employ an alternative means to achieve the same or substantially the same result
as that contemplated by such term, provision, covenant or restriction. It is
hereby stipulated and declared to be the intention of the parties that they
would have executed the remaining terms, provisions, covenants and restrictions
without including any of such that may be hereafter declared invalid, illegal,
void or unenforceable.

                  (l) Future Subsidiary Guarantors. The Company agrees to cause
each subsidiary that becomes a Subsidiary Guarantor under the Indenture to
become jointly and severally liable for the performance of the Company's
obligations under this Agreement.

                  Please confirm that the foregoing correctly sets forth the
agreement among the Company and the Initial Purchaser.

                     [WINSTEAD SECHREST & MINICK LETTERHEAD]




                                 August 11, 1998


Board of Directors
Splitrock Services, Inc.
8665 New Trails Drive, Suite 200
The Woodlands, Texas 76381

Gentlemen:

         We have acted as counsel to Splitrock Services, Inc. (the "Company") in
connection with the Registration Statement on Form S-4 (the "Registration
Statement") to be filed with the Securities and Exchange Commission in
connection with the registration under the Securities Act of 1933, as amended,
of $250 million aggregate principal amount of 11-3/4% Series B Senior Notes due
2008 of the Company (the "Exchange Notes") to be offered and issued by the
Company under an Indenture dated as of July 24, 1998 by and among the Company
and Bank of Montreal Trust Company, as Trustee.

         We have examined the Indenture, the global note issued under the
Indenture and such statutes, corporate records and documents, certificates of
corporate and public officials and such other instruments and documents as we
have deemed necessary or appropriate for the purposes of the opinions expressed
herein.

         Based upon the foregoing and subject to the qualifications, assumptions
and other statements set forth herein, we are of the opinion that, upon issuance
thereof in the manner described in the Registration Statement, the Exchange
Notes will be valid and binding obligations of the Company, except as the
enforceability thereof may be limited by bankruptcy, insolvency, reorganization
or other similar laws affecting the enforcement of creditors' rights generally
and by general equitable principles (regardless of whether the issue of
enforceability is considered in a proceeding in equity or at law).

         The opinion expressed above assumes that the Exchange Notes issued
under the Indenture have been duly executed, authenticated, issued and delivered
in accordance with the provisions of the Indenture upon exchange for the 11-3/4%
Senior Notes due 2008 as provided for therein.

         Except as otherwise stated below, the opinions expressed herein are
based upon, and limited to, the laws of the State of Texas and the United States
and the Delaware General Corporation Law, and to case decisions reported as of
this date under such laws, and to facts known to us on this date,

and we do not undertake to provide any opinion as to any matter or to advise any
person with respect to any events or changes occurring subsequent to the date of
this letter.

         The opinions expressed in this letter are provided as legal opinions
only and not as any guaranties or warranties of the matters discussed herein,
and such opinions are strictly limited to the matters stated herein, and no
other opinions may be implied. This opinion letter is intended solely for your
benefit. Without our prior written consent, the opinions expressed herein may
not be published or relied upon by you other than in connection with the
Registration Statement or the transactions contemplated therein, or published or
relied upon by any other person in connection with any matter or in any manner
whatsoever.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to this Firm under the heading
"Legal Matters" in the Prospectus which is part of the Registration Statement.

                                         Very truly yours,

Part I - 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 my provide to you. The term does not
                  include licensed internal code or Materials.

                                                   
                                                             CONFIDENTIAL
                                                       ATTORNEY-CLIENT PRIVILEGE

         "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 Count" 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 not be
         effective against or in favor of either party, unless and until each
         party agrees to each appropriate set of Transition Documents in 
         writing.


                                                             CONFIDENTIAL
                                                       ATTORNEY-CLIENT PRIVILEGE



<PAGE>   4



         CONFLICTING TERMS

         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 changes);

         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:

                                                             CONFIDENTIAL

<PAGE>   5





         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

         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.

                                                             CONFIDENTIAL

         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.

Part 6 - SplitRock Services

6.1      Description

         We will provide you network services consisting of the following
         components:

         o        Dial access network as described in Section 6.1.1 

         o        ATM backbone network as described in Section 6.1.2

         o        Regional Servers connectivity as described in 6.1.3 

         o        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:

         o        a physical site presence with modem ports; or

         o        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).



                                                             CONFIDENTIAL

         We shall be responsible for:

         o        inbound communication facilities (such as hunt groups,
                  measured business lines or DID trunks);

         o        modem hardware including ports and chassis; and

         o        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 term 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, T1, 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
         bandwith 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 LDR200 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 bandwith 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

         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 my 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.

6.2      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);

                                                             CONFIDENTIAL
                                                       ATTORNEY-CLIENT PRIVILEGE



<PAGE>   17





         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 testing.

                                                             CONFIDENTIAL
                                                       ATTORNEY-CLIENT PRIVILEGE



<PAGE>   18





                  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:

                  o        the Total Scheduled Minutes of Availability for the
                           site;

                  o        minus the Total Unscheduled Outage Minutes for the
                           site;

                  o        divided by the Total Scheduled Minutes of
                           Availability for the site.

 (Total Scheduled Minutes of Availability) - (Total Unscheduled Outage Minutes)
 ------------------------------------------------------------------------------
 (Total Scheduled Minutes of Availability)

                  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

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

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 deliver 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 [Confidential material
         omitted and filed separately with the Commission]

                  January 1, 1998 through December 31, 1998 [Confidential 
         material omitted and filed separately with the Commission]

                  All subsequent years [Confidential material omitted and filed 
         separately with the Commission]

<PAGE>   21

         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 [confidential material
omitted and filed separately with the Commission] 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) 
[confidential material omitted and filed separately with the Commission] 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;

         $3,500,00 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) 

    [confidential material omitted and filed separately with the Commission]

                   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

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 [confidential material
                  omitted and filed separately with the Commission] 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
                  [confidential material omitted and filed separately with the
                  Commission] 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 data 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 usor 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.

         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

                                                             CONFIDENTIAL

         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 levels, 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.

If the arbitrators' judgement 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.

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 an 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 partners ("Other Business"); provided that, at least thirty days prior
to your entering into any agreement of 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 in our costs unless we both agree on the amount of increased revenues
which will bear a reasonable relationship to such increase in our costs;
provided that, if we cannot agree on the amount of such increased revenues, we
shall have no obligation to provide our Services required for such Other
Business.

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.

         If you request us to develop a new product, service or enhancement for
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 of 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




                                                             CONFIDENTIAL

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.

                          performing services, under the direction and
                          supervision of Provider's management, relating to the
                          operation of the Network Assets. Provider shall, each
                          month, reimburse Company for the monthly base salary
                          of each independent contractor and each Direct
                          Employee as set forth in Schedule I.C. attached
                          hereto plus an amount equal to 30% of each
                          independent contractor's monthly compensation or
                          Direct Employee's monthly base salary. All offers by
                          Provider to Direct Employees and contractors shall be
                          made on the same date and shall be made no later than
                          July 31, 1997. No person listed on Schedule I.C.
                          shall become an employee or contractor, as
                          appropriate, of Provider until Provider offers such
                          persons listed on Schedule I.C. employment or
                          contractor position, as appropriate, and such person
                          accepts that position and commences employment, or,
                          working under contract, with Provider. Provider shall
                          offer all of the persons listed on Schedule I.C.
                          employment or independent contractor contracts, as
                          appropriate, commencing no later than the End Date on
                          terms and conditions no less favorable than such
                          terms and conditions currently enjoyed by each
                          individual Direct Employee or independent contractor.
                          With respect to those former IBM employees who are
                          now Company employees (specifically Tom Isaacson, Jim
                          Moore, Anthony Matera and Daniel Cain), the parties
                          shall cooperate to eliminate the potential for
                          reduction in their pension benefits, by, for example,
                          delaying the commencement date of such employment by
                          Provider or Company continuing to lease each such
                          employee to Provider even after the termination of
                          this Agreement.

                          With respect to those Company employees whose
                          matching contribution to their 401 (k) plan offered
                          by Company has not yet vested, and whose right to
                          otherwise receive such funds shall lapse, if such
                          employees resign from Company to work at Provider,
                          Company shall act to vest such Employees' unvested
                          portion of their 401(k).

                          Company hereby indemnifies and shall hold Provider
                          harmless from any and all costs, demands, claims,
                          liabilities including reasonable attorney's fees and
                          costs, arising out of the employment with Company of
                          any Direct Employee, including



                                                             CONFIDENTIAL

                          any claim under any and all applicable plant closing
                          or other similar laws, or ERISA, or other applicable
                          law.

                          Provider hereby indemnifies and shall hold Company
                          harmless from any and all costs, demands, claims,
                          liabilities including reasonable attorney's fees and
                          costs, arising out of the employment with Provider of
                          any Direct Employee, including any claim under any
                          and all applicable plant closing or other similar
                          laws, or ERISA, or other applicable law.

         (D)              Network Support Functions. Company further agrees to
                          provide network support functions to Provider such as
                          accounting and analysis (but excluding financial
                          projections), human resources, and purchasing
                          functions (except that purchase advice shall be
                          provided by Company, but purchase orders shall be
                          issued on Provider's account), at the monthly costs
                          to Provider included in Schedule I.D. Company will
                          provide each such service monthly but only upon
                          request and until such time as Provider terminates
                          the service. If Provider terminates any service under
                          this Paragraph I.D., it may not have such service
                          reinstated.

         (E)              Network-Related Costs. Company agrees to incur only
                          reasonable and customary amounts in operating the
                          network assets during the Transition Period,
                          consistent with past practices, which amounts will
                          include routine monthly payments for network
                          contracts, in effect as of the Effective Date, with
                          payment amounts and terms previously disclosed to
                          Provider. Provider will reimburse Company for such
                          amounts on a monthly basis and within 15 days of
                          receipt of a detailed invoice for such
                          network-related expenses incurred during such month,
                          which expenses shall not include any amount for
                          non-cash expenses (including without limitation
                          depreciation, amortization and any expense increase
                          attributable to events occurring prior to July 1,
                          1997).  Further, in no event shall Provider be liable
                          for reimbursing Company for any payments incurred by
                          reason of Company's breach or termination of
                          network-related agreements. Company will not incur
                          any new reimbursable network related costs for the
                          purchase of network equipment or for new services in
                          excess of $10,000, without Provider's prior written
                          consent. For example, Provider will pay reasonable
                          and customary costs associated with the classes of
                          expenses listed on Schedule I.

         (F)              POP Leases. During the Transition Period, (i) Company
                          will maintain all of its Point of Presence ("POP")
                          real estate leases in full force and effect at all of
                          the locations listed on Schedule I.F. attached hereto
                          entitled "Prodigy POP Site Remaining Lease Liability
                          Analysis," and (ii) Provider shall reimburse Company
                          for such lease payments based on the rental rates
                          listed in Schedule I.F. attached hereto. From and
                          after the Effective Date of this Agreement Provider
                          will furnish Company a list of POP site leases as it
                          determines it desires to keep ("Acceptable POP
                          Sites") and on or prior to October 1, 1997 Provider
                          will furnish a complete list of all Acceptable POP
                          Sites. After

<PAGE>   4
                          providing Company with the list of the Acceptable POP
                          Sites, Provider will commence negotiations with such
                          POP site lessors to assume, assign or execute new
                          leases for such sites.  Provider's notice to Company
                          of the list of Acceptable POP Sites shall not relieve
                          Company of its obligations described in first
                          sentence of this section F(i), except with respect to
                          any POP site that Provider has notified Company shall
                          be terminated. Further, unless Provider notifies
                          Company that, as to any POP lease which expires
                          between July 1, 1997 and the December 31, 1997,
                          Provider does not designate such lease as an
                          Acceptable POP Site, Company shall use reasonable
                          efforts to renew such lease through the End Date.
                          From and after December 31, 1997 the Company shall be
                          responsible for every lease which Provider did not
                          designate as an Acceptable POP Site. In selecting
                          those POP site leases which are not Acceptable POP
                          Sites, Provider shall provide notice to Company of
                          the access numbers if any to be discontinued, and the
                          new access numbers to replace such POP sites which
                          are not Acceptable POP Sites, at least sixty (60)
                          days before the termination of such access numbers,
                          so that continuity of service may be provided to
                          Company's customers. Provider acknowledges that as
                          of approximately June 1, 1997 Company has not sought
                          to renew any POP leases. Nothing in this Transition
                          Services Agreement shall cause any reduction in local
                          access telephone numbers to be made available to
                          Company's customers.

                          Provider shall use reasonable efforts to create its
                          new POPs in areas where Company's POPs may be
                          expiring, and replacements are needed. Upon the
                          expiration of all leases for those sites which are not
                          acceptable POP sites, Provider shall deliver the
                          premises back to each applicable landlord in
                          accordance with the terms of each applicable lease.
                          Provider shall have the right to dispose of any
                          furniture, fixtures or equipment not otherwise

         (E)              Entire Agreement, Amendments and Waivers. This
                          Agreement, together with all schedules hereto,
                          constitutes the entire agreement among the parties
                          pertaining to the subject matter hereof and
                          supersedes all prior agreements, understandings,
                          negotiations and discussions, whether oral or
                          written, of the parties. No supplement, modification
                          or waiver of this Agreement shall be binding unless
                          executed in writing by the party to be bound thereby.
                          No waiver of any of the provisions of this Agreement
                          shall be deemed or shall constitute a waiver of any
                          other provision hereof (whether or not similar), nor
                          shall such waiver constitute a continuing waiver
                          unless otherwise expressly provided.

         (F)              Counterparts. This Agreement may be executed in one
                          or more counterparts, each of which shall be deemed
                          an original, but all of which together shall
                          constitute one and the same instrument.

         (G)              Invalidity. In the event that any one or more of the
                          provisions contained in this Agreement or in any
                          other instrument referred to herein, shall, for any
                          reason, be held to be invalid, illegal or
                          unenforceable in any respect, such invalidity,
                          illegality or unenforceability shall not affect any
                          other provision of this Agreement or any other such
                          instrument.

         (H)              Alternative Dispute Resolution. In the event of a
                          dispute between the parties arising out of or
                          relating to this Agreement, or the breach thereof,
                          the parties 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. Each party agrees to respond
                          within three business days to any reasonable request
                          for information made by the arbitrators. 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

<PAGE>   8
                          arbitrator or arbitrators shall be appointed, upon
                          application by the interested party, by the American
                          Association of Arbitration (AAA).

                          The arbitrators shall apply the arbitration rules of
                          the AAA, and the arbitration proceedings shall take
                          place in Westchester County, New York.

                          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 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 Provider's failure to make
                          timely payments due to Company), then the parties
                          agree to continue to perform their respective
                          obligations under this Agreement until an agreement
                          is reached through mediation or the arbitrators
                          render a decision, whichever is applicable.

         (I)              No Third Party Rights. Nothing in this Agreement,
                          shall confer on any person or business entity, other
                          than the parties hereto, and their respective
                          successors and assigns, any rights, obligations,
                          remedies or liabilities.

         (J)              Headings. The headings of the Articles and Sections
                          herein are inserted for convenience of reference only

                          meaning or interpretation of this Agreement.

         IN WITNESS WHEREOF, the parties hereto have executed this Agreement,
or have caused this Agreement to be duly executed on their respective behalf by
their respective officers thereunto duly authorized, as of the day and year
first above written.

                        NETWORK IMPLEMENTATION AGREEMENT


THIS NETWORK IMPLEMENTATION AGREEMENT (this "Agreement"), effective as of April
23, 1998 (the "Effective Date"), is entered into by and between Ericsson Inc., a
Delaware corporation ("Ericsson"), and Splitrock Services, Inc., a Texas
corporation ("Splitrock").

WHEREAS, Splitrock desires to obtain from Ericsson, and Ericsson is willing to
provide to Splitrock, the products and services relating to Splitrock's national
network deployment of 99 ISP Points of Presence, in accordance with and subject
to the terms and conditions of this Agreement.

NOW, THEREFORE, Ericsson and Splitrock hereby agree as follows:

 1.    Agreement. During the term of this Agreement, Splitrock will purchase
       from Ericsson, and Ericsson will provide to Splitrock, the products and
       services as set forth in the statement of work attached hereto as Exhibit
       A (the "Statement of Work") and such additional products and services as
       Splitrock may reasonably request and as the parties may mutually agree
       in writing from time to time, all in accordance with and subject to the
       terms and conditions of this Agreement.

 2.    Term. The term of this Agreement will commence on the Effective Date and
       will continue unless earlier terminated in accordance with the provisions
       hereof.

 3.    Prices and Fees. With respect to the products and services to be provided
       by Ericsson to Splitrock as set forth in the Statement of Work, Splitrock
       will pay to Ericsson the prices and fees set forth in the Statement of
       Work.

 4.    Out-of-pocket Expense. Except as otherwise expressly provided herein,
       Splitrock will pay or reimburse Ericsson for any reasonable out-of-pocket
       expenses reasonably incurred by Ericsson, with Splitrock's prior written
       approval, in connection with the performance of this Agreement.

 5.    Taxes. Splitrock will be responsible for, and will pay or reimburse
       Ericsson for, any sales, use excise or other taxes, however designated or
       levied (excluding any taxes paid by Ericsson based on its profits), based
       upon this Agreement, any amounts payable to Ericsson hereunder, or any
       services, systems, materials or goods provided to Splitrock hereunder or
       their use.

 6.    Invoicing and Payment. From time to time as contemplated hereby, Ericsson
       will submit to Splitrock an invoice for the amounts then due and payable
       to Ericsson hereunder. Each such invoice will be due and payable to
       Ericsson within thirty days from the date of the invoice. Any sum due to
       Ericsson hereunder that is not



<PAGE>   2


       paid when due will bear interest thereafter until paid at a rate equal to
       the lesser of 1.5% per month or the maximum rate allowed by applicable
       law.

 7.    Delivery. Unless otherwise mutually agreed in writing by the parties, the
       products provided by Ericsson to Splitrock hereunder will be shipped by
       Ericsson to the applicable designated sites. Risk of loss of such
       products will pass to Splitrock upon Ericsson's placement of the shelter
       in which such products are housed on the ground at the designated site.
       Title to such products will pass to Splitrock when such products have
       been paid for in full by Splitrock to Ericsson.


 8.    Warranty. Ericsson warrants and agrees that it will perform the services 
       hereunder in a good and workmanlike manner. The foregoing warranty is for
       a warranty period of six (6) months following the date of acceptance. In
       addition, Ericsson warrants that:

       (a)    Ericsson has all right, title and ownership interests and/or
              licenses necessary to perform its obligations under this
              Agreement, and the products sold by Ericsson hereunder will be
              free and clear of any and all liens, encumbrances or security
              interests of any third party.

       (b)    Ericsson will assign any and all warranties with respect to each
              product sold by Ericsson to Splitrock hereunder if and to the
              extent allowed by the supplier of such product.

       EXCEPT AS OTHERWISE EXPRESSLY PROVIDED HEREIN, THERE ARE NO, AND ERICSSON
       HEREBY DISCLAIMS ALL, OTHER WARRANTIES, WHETHER IMPLIED, EXPRESS OR
       STATUTORY, WITH RESPECT TO THE PRODUCTS AND SERVICES PROVIDED TO
       SPLITROCK HEREUNDER, INCLUDING WITHOUT LIMITATION WARRANTY OF
       MERCHANTABILITY OR FITNESS FOR A PARTICULAR USE.

 9.    Rights in Software. With respect to all and all software components of
       the products provided by Ericsson hereunder and related documentation
       (collectively, the "Software"), Ericsson hereby grants to Splitrock, and
       Splitrock hereby accepts from Ericsson, a perpetual, non-exclusive and
       non-transferable license to use and possess the Software in strict
       accordance with the following use provisions:

       (a)    Splitrock will use the Software solely as an integral part of the
              products in which the Software is originally installed or embedded
              and for the operation of such products.

       (b)    Splitrock may make only one copy of the Software for backup or
              archival purpose; provided that any such copy will contain all
              proprietary notices, including the copyright notices of Ericsson
              or its licensor, which appear on or are encoded within the
              Software.


<PAGE>   3
       (c)    The Software (including any and all copies thereof) shall remain
              the exclusive property of Ericsson or its licensor.

       (d)    Splitrock may not merge the Software with other software to form a
              derivative work or otherwise modify or alter the Software in any
              manner.

       (e)    Splitrock may not reverse engineer, decompile or otherwise derive
              the source code from the Software.

10.    Confidentiality. Each party agrees that all confidential documents, work
       product and information (including all computer code and related
       materials) received or otherwise obtained from the other party pursuant
       to this Agreement, whether before or after the Effective Date, will be,
       and will be deemed to have been, received in confidence and will be used
       only for the purpose of carrying out the obligations of, or as otherwise
       contemplated by, this Agreement. Without the other party's prior written
       consent, neither party may disclose any such information to any third
       party, and each party will disclose such information only to such of its
       officers, employees and agents that have a need to know such information
       for the purposes contemplated hereby. However, the provisions of this
       Section 10 will not apply to any such information that (i) is or becomes
       generally available to the public without the fault or negligence of
       either party, (ii) is already in the possession of the receiving party
       without being subject to another confidentiality obligation, (iii) is or
       becomes available to the receiving party on a non-confidential basis from
       a source other than the disclosing party; provided that such source is
       not bound by a confidentiality obligation of the disclosing party, (iv)
       is required to be disclosed pursuant to an arbitration proceeding
       conducted in accordance with this Agreement, or (v) is required to be
       disclosed pursuant to a requirement of any governmental authority or any
       statute, rule or regulation; provided that the party required to disclose
       such information of the other party provide to the other party notice of
       such requirement of any such disclosure and cooperates with the other
       party to prevent or restrict any such disclosure to the extent allowed by
       applicable law.

 11.   Infringement Indemnification, Ericsson will, at its expense, indemnify,
       defend and hold Splitrock harmless from and against any claim or action
       asserted or brought against Splitrock alleging that the products provided
       by Ericsson hereunder directly infringes any United States patent,
       copyright, trademark or trade secret of any third party; provided that
       Splitrock (i) promptly notifies Ericsson of any such claim or action,
       (ii) provides to Ericsson all reasonably necessary assistance in
       defending any such claim or action, (iii) permits Ericsson to direct the
       defense or any such claim or action, including all settlement discussions
       or decisions.

       In the event the use of the Products by Splitrock as contemplated hereby
       is enjoined, or in the event that Ericsson desires to minimize its
       potential liability



<PAGE>   4
       hereunder, Ericsson may fulfill its obligations hereunder by (i)
       substituting non-infringing equivalent products, (ii) modifying the
       infringing products or portion thereof, so that such products no longer
       infringe but remain functionally equivalent, (iii) obtain for Splitrock,
       at Ericsson's expense, the right to continue the use of such Products, or
       (iv) if none of the preceding is commercially feasible, refund to
       Splitrock the purchase price for the infringing products, less the
       accumulated depreciation or amortization of such products as reflected in
       Splitrock's books. This Section 11 states Ericsson's entire liability for
       infringement of patent, copyright, trademark or trade secret.

       Ericsson's indemnification obligations set forth in this Section 11 will
       not apply to any infringement arising from (i) modification of the
       products by anyone other than Ericsson, (ii) any combination of the
       products with products or services provided by Splitrock or any third
       party, or (iii) any products developed by Ericsson for Splitrock in
       strict compliance with Splitrock's written instructions. Splitrock agrees
       to indemnify, defend and hold Ericsson harmless from and against any and
       all claims or actions asserted or brought against Ericsson based upon any
       of the foregoing infringement circumstances caused by Splitrock.

 12.   Mutual Indemnity. Each party will indemnify, defend and hold the other
       party harmless from any and all actions or claims to the extent such
       actions or claims arise out of or result from any negligent act or
       omission or willful misconduct of the indemnifying party or its
       employees, agents or contractors.

 13.   Termination for Cause. In the event that either party materially or
       repeatedly defaults in the performance of any of its duties or
       obligations hereunder (except for a default in payments to Ericsson) and
       does not substantially cure such default within thirty (30) days after
       being given written notice specifying such default, then the party not in
       default may, by giving written notice thereof to the defaulting party at
       any time thereafter and before such default is substantially cured,
       terminate this Agreement as of the date specified in the notice of
       termination. In addition to other available remedies, in the event that
       Splitrock defaults in the performance of any of its duties or obligations
       hereunder (including without limitation default in payments to Ericsson),
       Ericsson may suspend the performance of any of its duties or obligations
       hereunder until such default is cured by Splitrock to Ericsson's
       reasonable satisfaction, and Splitrock will pay to Ericsson an addition
       amount equal to the charges, costs and expenses reasonably incurred by
       Ericsson as a result of any such default by Splitrock.

 14.   Termination for Non-Payment. In the event that Splitrock defaults in the
       payment when due of any amount due to Ericsson hereunder and does not
       cure such default within ten (10) days after being given written notice
       specifying such default, then Ericsson may, by giving written notice
       thereof to Splitrock at any time thereafter and before such default is
       cured, terminate this Agreement as of the date specified in the notice of
       termination.

 15.   Limitation of Liability. In no event shall either party be liable for any
       special, incidental, indirect or consequential damages in connection with
       this Agreement, whether based on action or claim in contract, equity,
       negligence, intended conduct, tort or otherwise, even if such damages are
       foreseeable.

 16.   Dispute Resolution. The parties agree to resolve any dispute relating to
       this Agreement as set forth below:

       (a)    Negotiation. In the event of any dispute between the parties of
              any kind or nature arising out of or relating to this Agreement,
              upon the written request of either party, each party will appoint
              a designated representative whose task will be to meet with the
              other party's designated representative to resolve such dispute.
              Such representatives will discuss the dispute and negotiate in
              good faith to resolve the dispute or renegotiate the applicable
              section or provision without the necessity of any formal
              proceeding relating thereto. 

       (b)    Arbitration. If one of the designated representatives concludes 
              in good faith that amicable resolution through such continued
              negotiation of the matter in issue is not likely to occur, then,
              upon the request of either party, the dispute will be submitted to
              arbitration in accordance with the Commercial Arbitration Rules of
              the America Arbitration Association then in effect (the "Rules")
              or such other procedures as may be agreed upon by the parties.
              Three independent arbitrators will be selected in accordance with
              the Rules and the arbitrators will allow such discovery as is
              appropriate, consistent with the purposes of arbitration in
              accomplishing fair, speedy and cost effective resolution of
              disputes. Unless otherwise mutually agreed in writing by the
              parties, the arbitration proceedings will be conducted in the City
              of Dallas, Texas. The arbitrators will reference the rules of
              evidence of the Federal Rules of Civil Procedure then in effect in
              setting the scope of discovery. Judgment on the award rendered by
              the arbitrators may be entered in any court of competent
              jurisdiction; provided that any such award rendered by the
              arbitrators shall be strictly in conformance to and in accordance
              with the terms and conditions of this Agreement.

       (c)    Exclusive Remedy. Other than those matters involving injunctive
              relief as a remedy or any action necessary to enforce the award of
              the arbitrators, the parties agree that the provisions of this
              Section are a complete defense to any suit, action or other
              proceeding instituted in any court or before any administrative
              tribunal with respect to any dispute, controversy or claim
              arising under or in connection with this Agreement. Nothing in
              this Section prevents the parties from exercising their rights to
              terminate this Agreement in accordance with this Agreement.

       Any writing which may be mailed pursuant to the foregoing may also be
       delivered by express mail, telegraph, telex or facsimile and will be

       time change its address for notification purposes by giving the other
       party prior written notice of the new address and the date upon which it
       will become effective.


 20.   Relationship of Parties. Ericsson, in providing products and services to
       Splitrock hereunder, is acting only as an independent contractor and does
       not undertake by this Agreement or otherwise to perform an obligation of
       Splitrock, whether regulatory or contractual, or to assume any
       responsibility for Splitrock's business or operations. Ericsson has the
       sole right and obligation to supervise, manage, contract, direct,
       procure, perform or cause to be perform, all work to be performed by
       Ericsson hereunder unless otherwise provided herein.


 21.   Restriction on Hiring. Each party agrees that, during the term of this
       Agreement and for two years thereafter, it will not, except with the
       other party's prior written


<PAGE>   7


       consent, solicit for its employment, employ, engage as an independent
       contractor, otherwise obtain the services of any person employed then or
       within the preceding twelve months by the other party if that person was
       involved in the performance of this Agreement.


 22.   Force Majeure. Each party will be excused from performance hereunder for
       any period and to the extent that it is prevented from such performance,
       in whole or in part, as a result of delays caused by the other party or
       an act of God, natural disaster, war, civil disturbance, court order,
       labor dispute, third party non-performance, or other cause beyond its
       reasonable control and which it could not have prevented by reasonable
       precautions, including failures or fluctuations in electrical power,
       heat, light, air conditioning or telecommunications equipment, and such
       non-performance will not be a default hereunder or a ground for
       termination hereof.


 23.   Attorneys' Fees. If any legal action or other proceeding is brought for
       the enforcement of this Agreement of any arbitration award, or because of
       an alleged dispute, breach, default, or misrepresentation in connection
       with any of the provisions of this Agreement, the prevailing party will
       be entitled to recover reasonable attorneys' fees and other costs
       incurred in that action or proceeding, in addition to any other relief to
       which it may be entitled.


 24.   Third Party Beneficiaries. This Agreement is for the benefit of the
       parties hereto and is not intended to confer any rights or benefits on
       any third party, including any employees, creditor or affiliate of either
       party.


 25.   Severability. If any provision of this Agreement is illegal,
       unenforceable or void, then both parties will be relieved of all
       obligations arising under that provision, but only to the extent the
       provision is illegal, unenforceable or void. If the illegal,
       unenforceable or void provision does not relate to the payments to be
       made to Ericsson hereunder and if the remainder of this Agreement is
       capable of substantial performance, then each provision not so affected
       will be enforced to the extent permitted by law.


 26.   Waiver. No delay or omission by either party to exercise any right or
       power hereunder will impair that right or power or be construed to be a
       waiver thereof. A waiver by either party of any of the covenants to be
       performed by the other party or any breach thereof will not be construed
       to be a waiver of any succeeding breach thereof or of any other covenant
       herein contained.


 27.   Press Releases. All media releases, public announcements and public
       disclosures by either party relating to this Agreement or its subject
       matter, including promotional or marketing materials, will be
       coordinated with and approved in writing by the other party prior to
       release. This restriction does not apply to (i) any announcement intended
       solely for internal distribution by the



<PAGE>   8



       disclosing party, or (ii) any announcement required by legal, accounting
       or regulatory requirements beyond the reasonable control of the
       disclosing party.

 28.   Counterparts. This Agreement may be executed in several counterparts, all
       of which taken together will constitute one single agreement between the
       parties.


 29.   Amendments. No amendment, change, waiver or discharge hereof will be
       valid unless in writing and signed by an authorized representative of
       each party.


 30.   Governing Law. This Agreement will be governed by and construed in
       accordance with the laws, other than the choice of law rules, of the
       State of Texas.


 31.   Entire Agreement. This Agreement, including each schedule and exhibit
       referred to herein and attached hereto, each of which is incorporated
       herein for all purposes, constitutes the entire agreement between the
       parties with respect to the subject matter hereof and supersedes all
       prior and contemporaneous representations, understandings or agreements
       relating to the subject matter hereof.


IN WITNESS WHEREOR, Ericsson and Splitrock have each caused this Agreement to be
signed and delivered by its duly authorized representative, as of the Effective
Date.

for cash or credit, or for future delivery without assumption of any credit
risk, all as Secured Party deems advisable; provided, however that Debtor shall

public sale, and, to the extent permitted by law, upon any such private sale,

or equity of redemption, which right or equity of redemption Debtor hereby

disposition may occur, provided that Secured Party may provide Debtor shorter
notice or no notice, to the extent permitted by the UCC or other applicable
law.

or attempting to collect any of the Collateral, and to the payment of all
other amounts payable to Secured Party pursuant to Section 12 hereof; and
second, to the payment of the Obligations. Any surplus thereof which exists
after payment and performance in full of the Obligations shall be promptly paid
over to Debtor or otherwise disposed of in accordance with the UCC or other
applicable law. Debtor shall remain liable to Secured Party for any deficiency
which exists after any sale or other disposition or collection of Collateral.

     SECTION 9 Certain Waivers. Debtor waives, to the fullest extent permitted
by law, (i) any right of redemption with respect to the Collateral, whether
before or after sale hereunder, and all rights, if any, of marshalling of the
Collateral or other collateral or security for the Obligations; (ii) any right
to require Secured Party (A) to proceed against any person, (B) to exhaust any
other collateral or security for any of the Obligations, (C) to pursue any
remedy in Secured Party's power, or (D) to make or give any presentments,
demands for performance, notices of nonperformance, protests, notices of
protests or notices of dishonor in connection with any of the Obligations or
Collateral; and (iii) all claims, damages, and demands against Secured Party
arising out of the repossession, retention, sale or application of the proceeds
of any sale of the Collateral.

                               PURCHASE AGREEMENT

     This Purchase Agreement ("Agreement") is made as of July 1, 1997 by and 
between Splitrock Services, Inc. a Texas Corporation ("Splitrock") and Yurie
Systems, Inc., a Delaware corporation ("Yurie").

     1.  During the 18 months following execution of this Purchase Agreement,
Splitrock will purchase a minimum of twenty million dollars ($20 million) of
standard Yurie products at a discount of forty percent (40%) off of Yurie's
list prices for such products, pursuant to Yurie's commercial terms and
conditions. The parties shall negotiate annual purchase volume and discount
levels for each subsequent year.

     2.  Yurie's acceptance of Splitrock Purchase Orders shall be subject to
its standard practice and policies, including credit worthiness. If Yourie does
not accept a Purchase Order based on credit worthiness, Splitrock may reduce
its dollar volume commitment in paragraph 1. by the dollar amount of product
contained in such Purchase Order.

     3.  In consideration for Splitrock's purchase commitment in paragraph 1.,
Yurie is also agreeing to provide additional services to Splitrock in support
of the products purchased pursuant to paragraph 1, as outlined in attachment A.
Such services will be provided to Splitrock pursuant to Splitrock's
specifications and directions. Accordingly, Yurie makes no warranties or
representations regarding these additional services, nor any warranties or
representations of any products or materials, whether acquired by Yurie or
Splitrock, other than Yurie's commercial warranty terms for the Yurie products
purchased pursuant to paragraph 1.

     4.  Splitrock agrees to pay Yurie for the additional services in 
paragraph 3 on a time and materials cost basis, with costs to include direct 
labor and material, and overhead burdens applied to both labor and material,
consistent with Yurie accounting practices. Splitrock also agrees that it will
pay Yurie for any and all materials purchased as part of the additional services
being provided.

       2.1 Architecture

IBM will route all incoming data traffic using TCP/IP to a Splitrock server(s)
in Yorktown over two DS3 connections. IBM will route PLLP incoming traffic to
the Splitrock primary server located in Yorktown with the code name "Key West."
If the primary server is busy, IBM will route the data traffic to a Splitrock
secondary Key West server in Yorktown. Splitrock will provide IBM with the IP
address of the primary and secondary Key West servers for the PLLP access
sites.

IBM will provide to Splitrock formatted Radius records for authentication and
accounting for PPP sessions. The format of the Radius records will be mutually
agreed upon. Splitrock is responsible for provision, management and operation
of its servers at the Yorktown location, including the Radius server(s) and the
enabling of any required Proxy servers.

The DS3 connections that IBM provides to Splitrock are those DS3 Connections
which IBM currently provides to Prodigy. Splitrock Agrees to assume
responsibility for payment of such connections As of the effective date of this
Statement of Work and for the Prices as specified in the section "Charges."

Any additional connections or any changes to these connections will Be for an
additional fee to be agreed upon in writing by both Parties prior to the
provision of any additions or changes.

IBM will provide additional assistance to Splitrock, such as the Downloading of
IP address, to assist in the transition from the Regional server solution
employed by Prodigy and this Custom Solution. Such additional assistance shall
be for a fee to be Mutually agreed upon in writing by both parties prior to the
Provision of such assistance.

It is the responsibility of Splitrock to ensure that the transition Above has
been completed, such that IBM may perform its Responsibilities under this
Custom Solution. Under this Custom Solution, IBM does not provide for support
for the Prodigy PLS Solution.

       3. 0ur Other Responsibilities

          We will:

       1. provide you with a number for your operations group to contact our
          help desk support, which shall be available 24 hours a Day, 7 days a
          week;

       2. be responsible to license, develop, operate and maintain the Software
          on the equipment we provide;

       3. provide Splitrock with standard monthly reports that IBM Produces that
          are related to the Services provided under This Custom Solution,
          including information relative to Availability and traffic statistics;
          and

       4. Maintain the components we provide under this Custom Solution.



                                                                              3

IBM shall invoice Splitrock an amount equal to the Remote Call Forwarding
(RCF) costs that IBM incurs plus 22% of such costs for the dial connect time
associated with the Services as provided in the cities shown in Attachment A
Section 3.

The prices set forth above are not eligible for allowance or discount.

IBM will invoice Splitrock for all calls routed to a Splitrock server. The
sequence of a call is:

     -    the dial part goes off hook, modem synchronization;

     -    protocol management;

     -    call routed;

     -    Splitrock authentication;

     -    session live while user performing tasks;

     -    user initiates end of session; eventually resulting in modem 
          off-line and session termination (carrier dropped).

IBM will invoice Splitrock monthly for the sum of all calls, rounded by city to
the nearest hour.

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. IBM does not
intend to invoice Splitrock for calls that do not get routed to Splitrock
server, unless the Splitrock server does not accept the routed call. IBM does
intend to invoice Splitrock for all other partial calls.

IBM shall invoice Splitrock an amount equal to the sum of the carrier cost for
the DS3 connection plus an amount, determined by IBM, which represents the cost
IBM incurs in utilizing the backbone network (backbone router to backbone
router) in support of each such DS3 connection. These prices are not eligible
for allowance or discount and are not proratable.

IBM shall also invoice Splitrock $23,000 monthly for ongoing support costs.

IBM shall make reasonable efforts to provide invoices on or before the
fifteenth day of the month. Payment shall be made within 30 days of the date of
the invoice.

Applicable taxes, such as sales, use or excise taxes are not included in the
above charges.

IBM shall be responsible for sales, use, property and other taxes on machines,
software, or goods and services used or furnished by IBM in providing its
services to Splitrock.

Splitrock shall be responsible for sales, use, property and other taxes on
machines, software, or goods and services provided by Splitrock. Furthermore,
Splitrock shall be responsible for taxes assessed on the provision of Services
by IBM for Splitrock, or any charges by IBM to Splitrock under this Statement
of Work.


                                                                              5

<PAGE>   5



Charges and associated terms for generally available IBM Global Services'
Network Services are as we specify in the applicable IBM Service Descriptions
and Fee Schedules.

     6.    Dial Connection Information

IBM shall supply to Splitrock dial connection information regarding each dial
connection of a Splitrock End User. IBM will provide Splitrock with a record
layout of the format that will identify basic fields and optional fields. IBM
may add, delete or change optional fields at its sole discretion with thirty
days prior notice. IBM will not add, delete or change basic fields without
thirty days prior notification and the agreement of Splitrock.

     7.    Changes and Termination

IBM reserves the right to change its generally available dial city support and
corresponding phone number with prior notice, however, IBM will use
commercially reasonable efforts to provide Splitrock with 60 days prior notice
of such a change. Splitrock agrees to notify its customers that are affected by
the change.

Both parties agree that Services will be discontinued in cities listed in
Attachment A Section 3 effective July 1, 1998. Splitrock agrees to use
commercially reasonable efforts to provide IBM 60 days prior notice of a
reduction or expansion of 30% or greater in use in an Attachment A city.

IBM reserves the right to eliminate cities from Attachment A with 60 days
prior notice to Splitrock. Splitrock agrees to notify its customers of such
changes.

In the event that either party materially defaults in the performance of any of
its duties or obligations under this Statement of Work, and it 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 Statement of Work (herein
termination "for cause").

In the event that Splitrock is in default and IBM elects to terminate this
Statement of Work, then Splitrock may request an extension of this Statement
of Work of up to three months as a transition period, provided that IBM, at its
sole discretion, agrees to provide such an extension.

In the event that Splitrock terminates this Statement of Work because IBM is in
material default, then IBM will provide reasonable transition assistance to
Splitrock, for a period of up to six months. During this period, the terms of
this Statement of Work shall remain in force. This transition assistance is the
sole remedy of Splitrock for any "Breach" as defined above.


                                                                              6

8. Other Terms 

Splitrock shall indemnify (including reasonable attorney's fees), defend and
hold harmless IBM from any claim or action against IBM based on an allegation
that IBM's use of software provided by Splitrock infringes any patent,
copyright, trademark, trade secret or other proprietary right of any third
party.

The indemnification provided by Splitrock under the Statement of Work is in
addition to any other remedies available to IBM under the Statement of Work and
survives the termination of the Statement of Work.

Splitrock will not be allowed to test or repair the IBM dial network.

IBM is not responsible for telephone access charges associated with dialing the
IBM provided local dial telephone numbers.

Splitrock acknowledges and agrees that IBM is not responsible for any data, or
text, including the content, and, including its accuracy, which is received,
routed or sent as a result of the Services IBM provides hereunder.

Splitrock may request additional cities be added during the term of the
Statement of Work. Splitrock shall submit requests for additional cities in
writing to IBM and IBM shall provide a response to Splitrock within sixty (60)
days. Additional cities will be added under the same terms and prices as the
existing terms and prices under this Statement of Work.

9. Escalation Procedures

In the event of any dispute between the parties hereto arising from this
Statement of Work, then, upon the written request of either party, each of the
parties will appoint a designated representative to endeavor to resolve such
dispute. The designated representatives will negotiate in good faith to resolve
the dispute. Except for those disputes where injunctive relief may be an
appropriate remedy, no legal action relating to such dispute may be commenced
until the earlier of (i) the designated representatives conclude in good faith
that amicable resolution through continued negotiation of the matter in issue
does not appear likely or (ii) ninety (60) days after the start of such
negotiations.


                                                                              7

     The term "Program" includes an IBM Program and any non-IBM Program that we
     may provide to you. The term does not include Licensed Internal Code or
     Materials.

     SERVICE is performance of a task, provision of advice and counsel,
     assistance, or use of a resource (such as access to an information data
     base) we make available to you.

     SPECIFICATIONS is a document that provides information specific to a
     Product. For a Machine, we call the document "Official Published
     Specifications." For a Program, we call it "Licensed Program
     Specifications," or "License Information."

     SPECIFIED OPERATING ENVIRONMENT is the Machines and Programs with which a
     Program is designed to operate, as described in the Program's
     Specifications.

1.2  AGREEMENT STRUCTURE

     ATTACHMENTS

     Some Products and Services have terms in addition to those we specify in
     this Agreement. We provide the additional terms in documents called
     "Attachments," which are also part of this Agreement. We make the
     Attachments available to you for signature.

     TRANSACTION DOCUMENTS

     For each business transaction, we will provide you with the appropriate
     "Transaction Documents" that confirm the specific details of the
     transaction. Some Transaction Documents require signature, and others do
     not. The following are examples of Transaction Documents that must be
     signed by both of us with examples of the information they may contain:

     1.   addenda (contract-period duration, start date, and total quantity);
          and

     2.   statements of work (scope of Services, responsibilities, deliverables,
          Completion Criteria, estimated schedule, and charges).

     The following are examples of administrative, unsigned Transaction
     Documents with examples of the information they may contain;

     1.   exhibits (eligible Products by category);

     2.   invoices (item, quantity, price, and amount payable); and

     3.   supplements (Machine quantity and type ordered, price, estimated
          shipment date, and warranty period). Certain supplements may require
          signature if requested by either of us.

     CONFLICTING TERMS

     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 of these documents.

     OUR ACCEPTANCE OF YOUR ORDER

     A Product or Service becomes subject to this Agreement when we accept your
     order. We accept your order by doing any of the following:

     1.   sending you a Transaction Document;

     2.   shipping the Product; or

     3.   providing the Service.

     YOUR ACCEPTANCE OF ADDITIONAL TERMS

     You accept the additional terms in an Attachment or Transaction Document by
     doing any of the following:

     1.   signing the Attachment or Transaction Document;

     2.   using the Product or Service, or allowing others to do so; or

     3.   making any payment for the Product or Service.

1.3  DELIVERY

     We will try to meet your delivery requirements for Products and Services
     you order, and will inform you of their status. Transportation charges, if
     applicable, will be specified in a Transaction Document.



                                  PAGE 4 OF 19
<PAGE>   5

1.4  PRICES AND PAYMENT

     The amount payable for a Product or Service will be based on one or more
     of the following types of charges:

     1.   one-time (for example, the price of a Machine);

     2.   recurring (for example, a periodic charge for Maintenance Services);

     3.   time and materials (for example, charges for Hourly Services); or

     4.   fixed price (for example, a specific amount agreed to between us for
          Project Support Services).

     Depending on the particular Product, Service, or circumstance, additional
     charges may apply. We will inform you in advance whenever additional
     charges apply.

     For a Product with a one-time charge, payment is due on its Date of
     Installation. Recurring charges for a Product begin on its Date of
     Installation. Payment for Services is due as we specify, either in
     advance, as the work progresses, or after the work is completed. You agree
     to pay amounts due for Products and Services, including any late payment
     fees, as we specify in the invoice.

     If any authority imposes a duty, tax, levy, or fee, excluding those based
     on our net income, upon any transaction under this Agreement, then you
     agree to pay that amount as specified in the invoice or supply exemption
     documentation. You are responsible for personal property taxes for each
     Product from the date we ship it to you.

     One-time and recurring charges may be based on measurements of actual or
     authorized use (for example, number of users or processor size for
     Programs and meter readings for Maintenance Services). You agree to
     promptly notify us and pay any applicable charges if you change the basis
     of measurement for usage based charges. Recurring charges will be adjusted
     accordingly. We do not give credits or refunds for charges already due or
     paid. In the event that we change the basis of measurement, the changes
     will be subject to our price change terms.

     We may increase recurring charges for Products and Services (including
     hourly rates and minimums) by giving you three months' written notice. An
     increase applies on the first day of the applicable invoice period on or
     after the effective date we specify in the notice.

     We may increase one-time charges without notice. However, an increase to
     one-time charges does not apply to you if 1) we receive your order before
     the announcement date of the increase and 2) one of the following occurs
     within three months after our receipt of your order:

     1.   we ship you the Product;

     2.   with our authorization, you make an Additional License Copy of a
          Program or a copy of a Distribution Feature; or

     3.   a Program's group-upgrade charge becomes due.

     You receive the benefit of a decrease in charges for amounts which become
     due on or after the effective date of the decrease.


1.5  TYPES OF SERVICE FOR MACHINES

     We provide certain types of repair and exchange service either at your
     location or at our service center to keep Machines in, or restore them to,
     good working order.

     Under carry-in service, you may deliver the failing Machine or ship it
     suitably packaged (prepaid, unless we specify otherwise) to a location we
     designate. After we have repaired or exchanged the Machine, we will return
     it to you at our expense unless we specify otherwise.

     Under on-site service, we may repair the failing Machine at your site or
     exchange it, at our discretion, depending on the nature of the failure.



                                  PAGE 5 OF 19
<PAGE>   6

     When a type of service involves the exchange of a Machine or part, the item
     we replace becomes our property and the replacement becomes yours. You
     represent that all removed items are genuine and unaltered. The replacement
     may not be new, but will be in good working order and at least functionally
     equivalent to the item replaced. The replacement assumes the warranty and
     Maintenance Service status of the replaced item. Before we exchange a
     Machine or part, you agree to remove all features, parts, options,
     alterations, and attachments not under our service. You also agree to
     ensure that the item is free of any legal obligations or restrictions that
     prevent its exchange.

     You agree to:

     1.   obtain authorization from the owner to have us service a Machine that 
          you do not own; and

     2.   where applicable, before we provide service -

          a.   follow the problem determination, problem analysis, and
               service-request procedures that we provide,

          b.   secure all programs, data, and funds contained in a Machine, and

          c.   inform us of changes in a Machine's location.

1.6  PATENTS AND COPYRIGHTS

     For purposes of this Section, the term "Product" includes Materials (alone
     or in combination with Products we provide to you as a system) and Licensed
     Internal Code.

     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.

     If such a claim is made or appears likely to be made, you agree to permit
     us 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. We will then give
     you a credit equal to your net book value for the Product, provided you
     have followed generally-accepted accounting principles.

     This is our entire obligation to you regarding any claim of infringement.

     CLAIMS FOR WHICH WE ARE NOT RESPONSIBLE

     We have no obligation regarding any claim based on any of the following:

     1.   anything you provide which is incorporated into a Product;

     2.   your modification of a Product, or a Program's use in other than its
          Specified Operating Environment;

     3.   the combination, operation, or use of a Product with other Products
          not provided by us as a system, or the combination, operation, or use 
          of a Product with any product, data, or apparatus that we did not 
          provide; or

     4.   infringement by a non-IBM Product alone, as opposed to its
          combination with Products we provide to you as a system.



                                  PAGE 6 OF 19
<PAGE>   7

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 you are entitled to claim
     damages from us (including fundamental breach, negligence,
     misrepresentation, or other contract or tort claim), we are liable only
     for:

     1.   payments referred to in our patents and copyrights terms described
          above;

     2.   damages for bodily injury (including death) and damage to real
          property and tangible personal property; and

     3.   the amount of any other actual direct damages or loss, up to the
          greater of $100,000 or the charges (if recurring, 12 months' charges
          apply) for the Product or Service that is the subject of the claim.
          For purposes of this item, the term "Product" includes Materials and
          Licensed Internal Code.

          This limit also applies to any of our subcontractors and Program
          developers. It is the maximum for which we and our subcontractors and
          Program developers are collectively responsible.

     ITEMS FOR WHICH WE ARE NOT LIABLE

     Under no circumstances are we, our subcontractors, or Program developers
     liable for any of the following:

     1.   third-party claims against you for losses or damages (other than those
          under the first two items listed above);

     2.   loss of, or damage to, your records or data; or

     3.   special, incidental, or indirect damages or for any economic
          consequential damages (including lost profits or savings), even if we
          are informed of their possibility.

1.8  MUTUAL RESPONSIBILITIES

     Both of us agree that under this Agreement:

     1.   neither of us grants the other the right to use its trademarks, trade
          names, or other designations in any promotion or publication;

     2.   all information exchanged is nonconfidential. If either of us
          requires the exchange of confidential information, it will be made
          under a signed confidentiality agreement;

     3.   each is free to enter into similar agreements with others;

     4.   each grants the other only the licenses and rights specified. No
          other licenses or rights (including licenses or rights under patents)
          are granted;

     5.   each may communicate with the other by electronic means and such
          communication is acceptable as a signed writing. An identification
          code (called a "USERID") contained in an electronic document is
          legally sufficient to verify the sender's identity and the document's
          authenticity;

     6.   each will allow the other reasonable opportunity to comply before it
          claims that the other has not met its obligations;

     7.   neither of us will bring a legal action more than two years after the
          cause of action arose; and

     8.   neither of us is responsible for failure to fulfill any obligations
          due to causes beyond its control.

1.9  YOUR OTHER RESPONSIBILITIES

     You agree:

     1.   not to assign, or otherwise transfer, this Agreement or your rights
          under it, delegate your obligations, or resell any Service, without
          prior written consent. Any attempt to do so is void;



                                  PAGE 7 OF 19
<PAGE>   8

     2.   to acquire Machines with the intent to use them within your Enterprise
          and not for reselling, leasing, or transferring to a third party,
          unless either of the following applies -
          
          a. you are arranging lease-back financing for the Machines, or

          b. you purchase them without any discount or allowance, and do not
             remarket them in competition with our authorized remarketers;

     3.   to allow us to install mandatory engineering changes (such as those
          required for safety) on IBM Machines. Any parts we remove become our
          property. You represent that you have the permission from the owner
          and any lien holders to transfer ownership and possession of removed
          parts to us:

     4.   that you are responsible for the results obtained from the use of the
          Products and Services; and

     5.   to provide us with sufficient, free, and safe access to your
          facilities for us to fulfill our obligations.

1.10 IBM BUSINESS PARTNERS

     We have signed agreements with certain organizations (called "IBM Business
     Partners") to promote, market, and support certain Products and Services.
     When you order our Products or Services (marketed to you by IBM Business
     Partners) under this Agreement, we confirm that we are responsible for
     providing the Products or Services to you under the warranties and other
     terms of this Agreement. We are not responsible for 1) the actions of IBM
     Business Partners, 2) any additional obligations they have to you, or 3)
     any products or services that they supply to you under their agreements.

1.11 CHANGES TO THE AGREEMENT TERMS          

     In order to maintain flexibility in our Products and Services, we may
     change the terms of this Agreement by giving you three months' written
     notice. However, these changes are not retroactive. They apply, as of the
     effective date we specify in the notice, only to new orders (those we
     receive on or after the date of the notice) and to on-going transactions,
     such as licenses and Services.

     Otherwise, for a change to be valid, both of us must sign it. Additional
     or different terms in any order or written communication from you are void.

1.12 AGREEMENT TERMINATION

     You may terminate this Agreement on written notice to us following the
     expiration or termination of your obligations.

     Either of us may terminate this Agreement if the other does not comply with
     any of its terms, provided the one who is not complying is given written
     notice and reasonable time to comply.

     Any terms of this Agreement which by their nature extend beyond its
     termination remain in effect until fulfilled, and apply to respective
     successors and assignees.

1.13 GEOGRAPHIC SCOPE

     All your rights, all our obligations, and all licenses (except for Licensed
     Internal Code and as specifically granted) are valid only in the United
     States and Puerto Rico.

1.14 GOVERNING LAW

     The laws of the State of New York govern this Agreement.

IBM CUSTOMER AGREEMENT
PART 2 - WARRANTIES

2.1  THE IBM WARRANTIES

     WARRANTY FOR IBM MACHINES

     For each IBM Machine, we warrant that it:
     1.   is free from defects in materials and workmanship; and
     
     2.   conforms to its Specifications.

     The warranty period for a Machine is a specified, fixed period commencing 
     on its Date of installation.

     During the warranty period, we provide warranty service under the type of
     service we designate for the Machine or under the alternative service you
     select under Maintenance Services.

     For us to provide warranty service for a feature, conversion, or upgrade,
     we require that the Machine on which it is installed be 1) for certain
     Machines, the designated, serial-numbered Machine and 2) at an
     engineering-change level compatible with the feature, conversion, or
     upgrade.

     During the warranty period, we manage and install engineering changes that
     apply to the Machine.

     If a Machine does not function as warranted during the warranty period, we 
     will repair it or replace it with one that is at least functionally 
     equivalent, without charge. If we are unable to do so, you may return it
     to us and we will refund your money.

     WARRANTY FOR IBM PROGRAMS

     For each warranted IBM Program, we warrant that when it is used in the
     Specified Operating Environment, it will conform to its Specifications.

     The warranty period for a program commences on its Date of Installation
     and expires when its Program Services are no longer available.

     During the warranty period, we provide warranty service, without charge,
     for a Program Services. Program Services are available for a warranted
     Program for at least one year following its general availability.
     Therefore, the duration of warranty service depends on when you obtain
     your license.

     If a Program does not function as warranted during the first year after
     you obtain your license and we are unable to make it do so, you may return
     the Program to us and we will refund your money. To be eligible, you must
     have acquired the Program while Program Services (regardless of the
     remaining duration) were available for it.

     WARRANTY FOR IBM SERVICES

     For each IBM Service, we warrant that we perform it:
     
     1.   In a workmanlike manner, and
     
     2.   according to its current description (including any Completion
          Criteria) contained in this Agreement, an Attachment, or a
          Transaction Document.



                                  PAGE 9 OF 19
<PAGE>   10

     WARRANTY FOR SYSTEMS

     Where we provide Products to you as a system, we warrant that they are
     compatible and will operate with one another. This warranty is in addition
     to our other applicable warranties.

2.2  EXTENT OF WARRANTY

     If a Machine is subject to federal or state consumer warranty laws, our
     statement of limited warranty included with the Machine applies in place of
     these Machine warranties.

     The warranties may be voided by misuse, accident, modification, unsuitable
     physical or operating environment, operation in other than the Specified
     Operating Environment, improper maintenance by you, removal or alteration
     of Product or parts identification labels, or failure caused by a product
     for which we are not responsible.

     THESE WARRANTIES REPLACE ALL OTHER WARRANTIES, EXPRESS OR IMPLIED,
     INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
     PARTICULAR PURPOSE.

2.3  ITEMS NOT COVERED BY WARRANTY

     We do not warrant uninterrupted or error-free operation of a Product or
     Service.

     We will identify IBM Products that we do not warrant.

     Unless we specify otherwise, we provide Materials, non-IBM Products, and
     non-IBM Services on a "AS IS" basis. However, non-IBM manufacturers,
     suppliers, or publishers may provide their own warranties to you.

CUSTOMER AGREEMENT

PART 3 - MACHINES

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

3.1  TITLE AND RISK OF LOSS

     When we accept your order, we agree to sell you the Machine described in a
     Transaction Document. We transfer title to you or, if you choose, your
     lessor when we ship the Machine. However, we reserve a purchase money
     security interest in the Machine until we receive the amounts due. For a
     feature, conversion, or upgrade involving the removal of parts which become
     our property, we reserve the security interest until we receive the amounts
     due and the removed parts. You agree to sign an appropriate document to
     permit us to perfect our purchase money security interest.

     We bear the risk of loss for the Machine through its Date of Installation.
     Thereafter, you assume the risk.

3.2  PRODUCTION STATUS

     Each IBM Machine is manufactured from new parts, or new and used parts. In
     some cases, the Machine may not be new and may have been previously
     installed. Regardless of the Machine's production status, our warranty
     terms apply.

3.3  INSTALLATION        

     For the Machine to function properly, it must be installed in a suitable
     physical environment. You agree to provide an environment meeting our
     specified requirements for the Machine.

     We have standard installation procedures. We will successfully complete
     these procedures before we consider an IBM Machine (other than a
     Customer-set-up Machine) installed.

     You are responsible for installing a Customer-set-up Machine (we provide
     instructions to enable you to do so) and a non-IBM Machine.

     MACHINE FEATURES, CONVERSIONS, AND UPGRADES

     We sell features, conversions, and upgrades for installation on Machines,
     and, in certain instances, only for installation on a designated,
     serial-numbered Machine. Many of these transactions involve the removal of
     parts and their return to us. As applicable, you represent that you have
     the permission from the owner and any lien holders to 1) install features,
     conversions, and upgrades and 2) transfer ownership and possession of
     removed parts (which become our property) to us. You further represent that
     all removed parts are genuine and unaltered. A part that replaces a removed
     part will assume the warranty and Maintenance Service status of the
     replaced part.

     You agree to allow us to install the feature, conversion, or upgrade within
     30 days of its delivery. Otherwise, we may terminate the transaction and
     you must return the feature, conversion, or upgrade to us at your expense.

3.4  LICENSED INTERNAL CODE

     Certain Machines we specify (called "Specific Machines") use Licensed
     Internal Code (called "Code"). We own copyrights in Code. We own all copies
     of Code, including all copies made from them.

     We will identify each Specific Machine in a Transaction Document. If you
     are the rightful possessor of a Specific Machine, we grant you a license to
     use the Code (or any replacement



                                 PAGE 11 OF 19
<PAGE>   12

we provide) on, or in conjunction with, only the Specific Machine, designated
by serial number, for which the Code is provided. We license the Code to only
one rightful possessor at a time.

Under each license, we authorize you to do only the following:

1.   execute the Code to enable the Specific Machine to function according to
     its Specifications;

2.   make a backup or archival copy of the Code (unless we make one available
     for your use), provided you reproduce the copyright notice and any other
     legend of ownership on the copy. You may use the copy only to replace the
     original, when necessary; and

3.   execute and display the Code as necessary to maintain the Specific Machine.

You agree to acquire any replacement for, or additional copy of, Code directly
from us in accordance with our standard policies and practices. You also agree
to use that Code under these terms.

You may transfer possession of the Code to another party only with the transfer
of the Specific Machine. If you do so, you must 1) destroy all your copies of
the Code that were not provided by us, 2) either give the other party all your
IBM-provided copies of the Code or destroy them, and 3) notify the other party
of these terms. We license the other party when it accepts these terms by
initial use of the Code. These terms apply to all Code you acquire from any
source.

Your license terminates when you no longer rightfully possess the Specific
Machine.

ACTIONS YOU MAY NOT TAKE

You agree to use the Code only as authorized above. You may not do, for
example, any of the following:

1.   otherwise copy, display, transfer, adapt, modify, or distribute the Code
     (electronically or otherwise), except as we may authorize in the Specific
     Machine's Specifications or in writing to you;

2.   reverse assemble, reverse compile, or otherwise translate the Code unless
     expressly permitted by applicable law without the possibility of
     contractual waiver;

3.   sublicense or assign the license for the Code; or

4.   lease the Code or any copy of it.

PART 4 - PROGRAMS

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

4.1  LICENSE

     When we accept your order, we grant you a non-exclusive license for the
     Program. Programs are copyrighted and licensed (not sold).

4.2  LICENSE DETAILS

     Under each license, we authorize you to:

      1.  use the Program's machine-readable portion on only the Designated
          Machine or, if it is inoperable, a backup Machine. If the Designated
          Machine cannot assemble or compile the Program, you may assemble or
          compile it on another Machine.

          If a Program is stored on a network server solely for the purpose of
          being distributed to other Machines, it is not considered to be in
          use.

          Certain Programs IBM designates for home or travel use may be stored
          on the Designated Machine and another Machine, provided the Program is
          not in active use on both Machines at the same time.

          If you change the Designated Machine previously identified to us, you
          agree to notify us of the change end its date:

      2.  make and store copies of a Program, managed by a license management
          tool, on Designated Machines under control of that tool, but your use
          may not exceed the total number of users or amount of resource
          authorized;

      3.  do the following to support your authorized use as described above-

          a.   make copies of the Program, provided you reproduce copyright
               notices and any other legends of ownership on each copy or 
               partial copy, and

          b.   merge the Program into another Program; and

      4.  use any portion of the Program we 1) provide in source form, or 2)
          mark restricted (for example, "Restricted Materials of IBM") only to -

          a.   resolve problems related to the use of the Program, and

          b.   modify the Program so that it will work together with other
               products.

     You agree to comply with any additional terms (such as usage restrictions)
     we may place on a Program. We identify these in the Program's
     Specifications or in a Transaction Document.

     ACTIONS YOU MAY NOT TAKE

     You agree not to do any of the following:

      1.  sublicense, assign, or transfer (unless we specify otherwise in the
          Program Specifications) the license for any Program:

      2.  distribute any Program to any third party; or

      3.  reverse assemble, reverse compile, or otherwise translate any Program.

4.3  PROGRAM FEATURES NOT USED ON THE DESIGNATED MACHINE

     Some Programs have features that are designed for use on Machines other
     than the Designated Machine on which the Program is used. You may make
     copies of a feature and its documentation in support of your authorized use
     of the Program. Persons using a Machine outside of your Enterprise may use
     the copy only to access the associated Program. You agree to pay us for
     each copy you make of any feature we refer to as a "Distributed Feature." 



                                 PAGE 13 OF 19
<PAGE>   14

4.4  ADDITIONAL LICENSE COPIES

     You may order additional licenses for Programs. If you prefer, for each
     license we grant, rather than shipping you another copy of the Program, we
     will authorize you to make an additional copy (called an "Additional
     License Copy").

     For some Programs, you may make a copy under a Distributed System License
     Option (called a "DSLO" license). We charge less for a DSLO license than
     we do for the original license (called the "Basic" license). In return for
     the lesser charge, you agree to do the following while licensed under a
     DSLO:

      1.  have a Basic license for the Program;

      2.  provide problem documentation and receive Program Services (if any)
          only through the location of the Basic license; and

      3.  distribute to, and install on, the DSLO's Designated Machine, any
          release, correction, or bypass that we provide for the Basic license.

4.5  PROGRAM TESTING

     We provide a testing period for certain Programs to help you evaluate if
     they meet your needs. If we offer a testing period, it will start 1) 10
     days after we ship the Program or 2) on the day we authorize you to make
     an Additional License Copy. We will inform you of the duration of the
     Program's testing period.

     If you terminate your license during this period, we will credit you with
     any charges you may have paid for the Program.

     For the first order of each Distributed Feature, the testing period is the
     same as its associated Program.

     We do not provide a testing period for a Program under a DSLO license.

4.6  PACKAGED PROGRAMS

     We provide certain Programs together with their own license agreements.
     These Programs are licensed under the terms of the agreements provided
     with them.

4.7  PROGRAM PROTECTION

     For each Program, you agree to:
      1.  ensure that anyone who uses it (accessed either locally or remotely)
          does so only for your authorized use and complies with our terms
          regarding Programs;

      2.  maintain a record of all copies; and

      3.  if it is a licensed data base containing information we provide to
          you, allow access to the information contained in it only to your
          employees, agents, or subcontractors, and only in support of their
          work for you.

4.8  PROGRAM SERVICES

     We provide Program Services for warranted Programs and for selected other
     Programs. If we can reproduce your reported problem in the Specified
     Operating Environment, we will issue defect correction information, a
     restriction, or a bypass. We provide Program Services for only the
     unmodified portion of a current release of a Program.



                                 PAGE 14 OF 19
<PAGE>   15

     We provide Program Services 1) on an on-going basis (with at least six
     months' written notice before we terminate services for a Program), 2)
     until the date we specify, or 3) for a period we specify.

4.9  LICENSE TERMINATION

     You may terminate the license for a Program on one month's written notice
     or at any time during the Program's testing period.

     Licenses for certain replacement Programs may be acquired for an upgrade
     charge. In this event, when you license these Programs, you agree to
     terminate the license of the replaced Program.

     We may terminate any license we grant you under the terms of this Part if
     you do not meet your obligations regarding Programs.

     You agree to destroy all copies of the Program after license termination.
     However, you may keep a copy in your archives.

IBM CUSTOMER AGREEMENT

PART 5 - SERVICES

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

5.1  MAINTENANCE SERVICES

     We will restore the Machine to good working order or exchange it, based on
     the type of service you select from those available for the Machine. We may
     also perform preventive maintenance. We manage and install engineering
     changes that apply to IBM Machines. We provide Maintenance Services for
     selected non-IBM Machines.

     We will inform you of the date on which Maintenance Services begin. We may
     inspect the Machine within one month following that date. If the Machine is
     not in an acceptable condition for service, you may have us restore it for
     a charge. Alternatively, you may withdraw your request for Maintenance
     Services. However, you will be charged for any Maintenance Services which
     we have performed at your request.

     For a Machine under a usage plan, you agree to provide us with the meter
     reading as of the last working day of the period that the minimum
     maintenance charge covers.

     Maintenance Services do not cover accessories, supply items, and certain
     parts, such as batteries, frames, and covers. In addition, Maintenance
     Services do not cover service of a Machine damaged by misuse, accident,
     modification, unsuitable physical or operating environment, improper
     maintenance by you, removal or alteration of Machine or parts
     identification labels, or failure caused by a product for which we are not
     responsible. Unless otherwise agreed, Maintenance Services do not cover
     service of Machine alterations.

     ALTERNATIVE SERVICE DURING WARRANTY

     For certain Machines, you may choose alternative warranty service. We
     provide the alternative type of service for an additional charge. When the
     alternative service ends, we will continue Maintenance Services for the
     Machine under the same type of service you selected.

     MAINTENANCE SERVICES TERMINATION

     You may terminate Maintenance Services for a Machine on one month's written
     notice to us under any of the following circumstances:

     1.   after it has been under Maintenance Services for at least six months;

     2.   if you permanently remove it from productive use within your
          Enterprise;

     3.   as of the effective date of an increase in Maintenance Services
          charges; or

     4.   if you terminate coverage for a Machine also covered by a Maintenance
          Service Option because we 1) remove a Machine type from eligibility or
          2) increase total adjusted charges for Maintenance Services.

     We may terminate Maintenance Services for a Machine on three months'
     written notice, provided it has been under Maintenance Services for at
     least one year.

     Either of us may terminate service for any Machine if the other does not
     meet its obligations concerning Maintenance Services. On termination of
     service for a Machine, we will give you any applicable credit.

     MAINTENANCE SERVICE OPTIONS

     We provide Maintenance Service Options for certain Machines. We provide the
     terms specific to an Option in an Attachment or Statement of Work. We will
     inform you periodically of any changes. We will defer an unfavorable change
     (and all changes related to it) until the next anniversary of the start of
     your contract period, if you request it in writing before the effective
     date of the change.



                                 PAGE 16 OF 19
<PAGE>   17

5.2  CONTINUING SUPPORT SERVICES

     We provide Continuing Support Services on a contract-period basis to
     assist you in improving the availability of your systems. We provide the
     terms specific to a Service in an Attachment or Statement of Work. If we
     make a change to the terms that 1) affects your current contract period
     and 2) you consider unfavorable, on your request, we will defer it until
     the next anniversary of the start of the contract period.

     Each of us agrees to notify the other (before your current contract period
     expires) if they do not intend to renew.

     CONTINUING SUPPORT SERVICES TERMINATION

     You may terminate a Continuing Support Service by providing us one month's
     written notice upon fulfillment of any minimum commitments.

     The termination of Services with contract periods longer than one year
     results in adjustment charges. In this case, you agree to pay the lesser
     of:

     1.   the difference between the total charges you paid through the
          termination date and those you would have paid for the same period of
          time at the charge level of the next shorter contract period;

     2.   the monthly charge multiplied by the applicable adjustment charge
          factor; or

     3.   the total charges remaining to complete the contract period.

     When an increase results in a change to your total monthly charge for a
     Service of more than the adjustment charge we specify, you may terminate
     that Service on the effective date of the increase. Adjustment or
     termination charges do not apply in this case.

5.3  PROJECT SUPPORT SERVICES

     Following are examples of Project Support Services we make available to
     you:

     1.   Consulting Services, such as reengineering business processes,
          linking business and technology strategies, improving manufacturing
          processes, and enhancing application development and information
          processing capabilities. We are responsible for managing the
          engagement;

     2.   Custom Services, such as managing and performing project tasks to
          deliver Materials or acting as a prime contractor to deliver an
          integrated system that may consist of a combination of Products,
          Services, Materials, and other items. We are responsible for managing
          the project, unless specified otherwise in the Statement of Work; and

     3.   Hourly Services, such as assisting on a technical task. You are
          responsible for managing the project and for any results achieved.
          The Statement of Work will specify the hourly rate and estimated
          number of hours. The estimate is not a fixed-price commitment.
          Charges = (actual hours x rate) + expenses.

          Hourly Services end when the first of the following occurs: 1) you
          advise us, in writing, that further Services are not required, 2) we
          provide the specified number of hours, or 3) the estimated end date
          expires. You may authorize, in writing, additional hours or extension
          of the end date.

     PROJECT SUPPORT SERVICES TERMINATION

     Either of us may terminate a project on written notice to the other if the
     other does not meet its obligations concerning the Statement of Work. Upon
     termination, we will stop our work in an orderly manner as soon as
     practical.

     You agree to pay us for all Services we provide and any Materials we
     deliver through the project's termination and any charges we incur in
     terminating subcontracts.



                                 PAGE 17 OF 19
<PAGE>   18
5.4  THE STATEMENT OF WORK

     A separate Statement of Work will be signed by both of us for each Services
     transaction not covered by another Transaction Document. When we accept
     your order, we agree to provide the Services described in the Statement of
     Work.

     The Statement of Work includes, for example:

     1.   our respective responsibilities;

     2.   the specific conditions (called the "Completion Criteria"), if any,
          that we are required to meet to fulfill our obligations;   

     3.   a contract period for Maintenance and Continuing Support Services and
          an estimated schedule for Project Support Services that we provide for
          planning purposes; and

     4.   applicable charges (not including taxes) and any other terms.

     If a Statement of Work contains an estimated schedule, each of us agrees to
     make reasonable efforts to carry out our respective responsibilities
     according to that schedule. If the Statement of Work contains Completion
     Criteria, we will inform you when we meet each of them. You then have 10
     days to inform us if you believe that we have not met those criteria. The
     project is complete when we meet the Completion Criteria.

     CHANGES TO STATEMENTS OF WORK

     When both of us agree to change a Statement of Work other than as permitted
     in the Maintenance Service Options and Continuing Support Services Sections
     of this Agreement, we will prepare a written description of the agreed
     change (called a "Change Authorization"), which both of us must sign. The
     terms of a Change Authorization prevail over those of the Statement of Work
     and any of its previous Change Authorizations.

     Any change in the Statement of Work may affect the charges, estimated
     schedule, or other terms. Depending on the extent and complexity of the
     requested changes, we may charge for our effort required to analyze it.
     When charges are necessary, we will give you a written estimate and begin
     the analysis only on your written authorization.

     PERSONNEL

     Each of us will:

     1.   designate a coordinator who will represent each of us, respectively,
          in all matters concerning Project Support Services and other Services
          where applicable; and

     2.   be responsible for the supervision, direction, and control of our
          respective personnel.

     We will try to honor your requests regarding the assignment of our
     personnel to your project. However, we reserve the right to determine the
     assignment of our personnel.

     We may subcontract a Service, or any part of it, we provide to you, to
     subcontractors selected by us.

5.5  MATERIALS OWNERSHIP AND LICENSE

     We will specify Materials to be delivered to you. We will identify them as
     being "Type I Materials," "Type II Materials," or otherwise as we both
     agree. If not specified, Materials will be considered Type II Materials.

     Type I Materials are those, created during the Service performance period,
     in which you will have all right, title, and interest (including ownership
     of copyright). We will retain one copy of the Materials. You grant us 1) an
     irrevocable, nonexclusive, worldwide, paid-up license to use, execute,
     reproduce, display, perform, distribute (internally and externally) copies
     of, and prepare derivative works based on Type I Materials and 2) the right
     to authorize others to do any of the former.

     Type II Materials are those, created during the Service performance period
     or otherwise (such as those that preexist the Service), in which we or
     third parties have all right, title, and interest (including ownership of
     copyright). We will deliver one copy of the specified Materials to you. We
     grant you an irrevocable, nonexclusive, worldwide, paid-up license to use,
     execute, reproduce, display, perform, and distribute, within your
     Enterprise only, copies of Type II Materials.

     Each of us agrees to reproduce the copyright notice and any other legend of
     ownership on any copies made under the licenses granted in this Section.

1.0 STATEMENT OF WORK

This Statement of Work listed below shall be appended to and made a part of the
IBM Customer Agreement (Agreement) - and any applicable attachments - which is
hereby incorporated by reference. In the event of any contradiction,
inconsistency or ambiguity between the terms and conditions of the two
documents, this Statement of Work shall govern. This agreement represents the
entire agreement between the two parties regarding this matter and replaces any
prior oral or written communication.

This Statement of Work defines the scope of work to be accomplished by IBM. The
tasks to be performed by IBM are defined and an estimated schedule is provided.
In addition, the responsibilities of Splitrock Services, Inc. (Splitrock) are
listed.

Changes to this Statement of Work will be processed in accordance with the
procedure described in Appendix B, "Project Change Control Procedure". The
investigation and the implementation of changes may result in modifications to
the Estimated Schedule, Charges, or other terms of this Statement of Work.

The following are incorporated in and made part of this Statement of Work:

     Appendix A. Guidelines For Deliverable Materials

     Appendix B. Project Change Control Procedure

1.1 PROJECT SCOPE

This section describes the Services that IBM will provide Splitrock. You have
selected the following services:

o    Project Management Services

o    Installation Management Services

o    Right to locate Splitrock equipment to be serviced by IBM under this
     Statement of Work ("Splitrock Equipment") in IBM premises ("IBM
     Facilities") mutually agreed up by the parties ("IBM Sites").

The details of the selected Services are described in the following sections.

The Services described in this Statement of Work do not address the capability
of your systems to handle date data within and between the twentieth and
twenty-first centuries. You acknowledge that it is your responsibility to
assess your current systems and take appropriate action to migrate to Year 2000
ready systems.



                                       1

<PAGE>   4
1.2 KEY ASSUMPTIONS

The services to be provided under this Statement of Work and the associated
charges are based on the following assumptions. Any assumptions found invalid
could have an effect on price or schedule and will be handled in accordance
with the procedure described in Appendix B, "Project Change Control Procedure".

     o    General Assumptions

          1.   This contract supersedes and replaces the existing Field
               Technical Manager (FTM) contract by and between Prodigy Services
               Inc. and IBM (reference IBM contract #2G24711, dated 11/12/96).

          2.   Services will be provided during normal IBM business hours, 8:00
               AM to 5:00 PM, Monday through Friday, excluding IBM holidays.

          3.   IBM may use subcontractors to perform some of the proposed work.

          4.   IBM requires ten (10) business days' notice to begin work after
               contract acceptance.

          5.   IBM estimated time frames subjected to delays caused by
               Splitrock in delivering requested or required information may
               result in changes to the project schedule and/or additional
               charges. IBM will inform Splitrock as soon as is practical in
               this event and the change will be processed in accordance with
               the procedure described in Appendix B, "Project Change Control
               Procedure".

          6.   The price does not include: obtaining permits; cabling in
               asbestos or otherwise hazardous environments; drilling through
               walls, ceilings or floors; moving of furniture, desks or lift
               equipment.

          7.   IBM will have reasonable access to and from all areas and
               systems affected by performance of the tasks as defined in the
               1.3, "IBM Responsibilities" section of this Statement of Work.

          8.   Any work cancellation may require a commercially reasonable
               effort to reschedule the engagement. Cancellation within
               forty-eight (48) hours of a scheduled engagement will result in
               a charge of four (4) hours of labor for each scheduled IBM
               resource against the IBM Customer Engineering (CE) hours
               available for this project.

          9.   Splitrock personnel assigned to this project will have the
               technical skills necessary to participate in this effort.

          10.  Splitrock will provide IBM with a list of locations at contract
               start date.

          11.  Splitrock is responsible for all taxes.

          12.  Splitrock is responsible for all permits, licenses and rights of
               way. IBM will not be responsible for any costs or delays related
               to these permits, licenses or rights of way.

          13.  Splitrock is responsible for all expenses incurred in its
               performance on this Statement of Work.

     o    INSTALLATION ASSUMPTIONS

          1.   Any delay caused by Splitrock including, but not limited to,
               interference of work schedule, material delivery, change of
               work, or concealed conditions, resulting in an increase of cost
               to IBM to perform the work, will be handled in the manner
               described in Appendix B, "Project Change Control Procedure".

          2.   Splitrock is responsible for the network design and the
               selection of network equipment as it relates to the performance
               of the network.

          3.   IBM requires the following conditions to be met prior to the
               start of the installation of software:

               o    media format must match the target system;

               o    appropriate quantity of software licenses are supplied;

               o    the target system has adequate capability and capacity;

               o    required configuration information is available;

               o    software will be readily available at the point of
                    installation;

               o    supporting documentation and manufacturer's support
                    information will be supplied; and

               o    there is no conflict with proprietary software.

          4.   Installations will be made using the manufacturer's default
               settings. Software problem resolution will be charged at the
               applicable hourly rate and handled via the Project Change
               Control Procedure if the system does not properly perform when
               installed with the manufacturer's specifications. Note: Use of
               custom or proprietary software increases the probability of
               software problems.

          5.   Splitrock assumes all responsibility for data and application
               integrity, and may engage IBM to perform backup and restores at
               the applicable hourly rate.

          6.   Resolution of problems caused by system configurations or
               software not identified in this Statement of Work will be
               charged on an hourly basis and handled via the Project Change
               Control Procedure. IBM will install the hardware and software to
               the manufacturer's specifications. If the system does not
               function properly or the system is defective, then IBM will
               notify Splitrock.

          7.   IBM reserves the right to adjust the hourly rates in situations
               where insufficient information has been provided and a different
               skill level is required to complete the required task.

          8.   All hardware and software to be installed by IBM under this
               Statement of Work will be provided by Splitrock.

          9.   The project schedule will be developed by Splitrock. IBM will be
               provided the opportunity to modify the schedule to facilitate
               resource balancing.

     o    IBM SPACE ASSUMPTIONS

          1.   The IBM Sites and the non-IBM sites owned or leased by Splitrock
               are sometimes collectively called "Splitrock Local Sites" or

Splitrock Services (you) and International Business Machines Corporation (IBM)
agree that the following terms and conditions amend and/or add to the
referenced Agreement and the referenced Statement of Work (SOW). IBM will allow
Splitrock to house Splitrock Equipment in IBM Sites.

1. TERM

This Contract becomes effective on the date this Contract, signed by you, is
accepted by IBM. The Commencement Date of this Contract shall be the date
mutually agreed upon by you and IBM provided such date follows IBM's acceptance
of this Contract. IBM will indicate the Commencement Date in the Supplement.
The Term of this Contract will begin on such Commencement Date and continue
for a duration to the contract end date.

Unless notified by IBM to the contrary, you may renew this Contract for an
additional Term of one year. IBM will advise you of the terms and conditions
for such renewal. You must provide written notice to IBM by November 1, 1998 of
any intent to renew this contract.


                                      16


<PAGE>   19



2. EXISTING IBM SITES

Your right to house the Splitrock Equipment at each IBM Site will begin March
1, 1998 at 12:01 AM and will expire on February 28, 1999 at 11:59 PM unless
terminated earlier pursuant to the Statement of Work number 2H34516.

     o    The following list details the IBM Sites:

          Albuquerque
          Austin
          Birmingham
          Cincinnati
          Toledo
          Columbus
          Durham
          Grand Rapids
          Honolulu
          Jacksonville
          Louisville
          Melbourne
          Nashville
          Norfolk
          Pittsburgh
          Omaha
          Akron

If IBM does not have an IBM facility available to house Splitrock's Equipment,
Splitrock will be responsible for finding a new non-IBM Site. You agree to
advise IBM, at least 2 weeks in advance, of the date you will install Splitrock
Equipment at each IBM Site or non-IBM Site to ensure that the site is ready for
the Splitrock Equipment installation.

All new IBM Sites where Splitrock houses its equipment after March 1, 1998
through February 28, 1999 will have some fixed cost associated with the new IBM
Sites. The charges will be as follows:

$60 sq. ft., UPS-$6500, Project Management-$1400, Site Support-$5000

The site support cost includes supporting the new site for 90 days and training
for the CE. At the end of the 90 days, the new site will follow the same Terms
and Conditions as an existing site.

3. ACCESS

IBM will contact IBM personnel, or subcontractor personnel, responsible to
service your equipment and provide them access to IBM Sites during normal
business hours. However, outside normal business hours, IBM will contact such
personnel and will dispatch an IBM


                                      17
<PAGE>   20


representative to provide them access subject to the terms of the referenced
SOW. IBM will provide a list of personnel in each location for you to contact
for access 24 hours a day, 7 days a week.

4. HOUSING EQUIPMENT CHARGES-PAID QUARTERLY

You agree to pay IBM the Charge for each IBM Site. For new IBM Sites, this
Charge will be calculated using an annual rate of $60 per square foot for each
IBM Site.

5. PAYMENT AND TAXES

IBM will invoice you quarterly for the Housing Equipment Charge for each IBM
Site. Payment is due within 30 days of the date of invoice.

In addition to the Housing Equipment Charges under this Contract, you agree to
pay an amount equal to any taxes, other than real estate taxes, resulting from
this Contract, or any activities hereunder, exclusive of the taxes based upon
IBM's net income.

6. POINTS OF CONTACT

Prior to the Commencement Date of this Contract, each party will designate a 
person who will be the point of contact for the party in communicating with the
other party and will be responsible for coordinating activities under this
Contract.

7. WITHDRAWAL/TERMINATION

You may withdraw IBM Sites or terminate this Contract prior to the end of its
Term, upon thirty (30) days written notice to IBM. IBM may terminate this
contract or Splitrock's rights as to any SLS in accordance with Section 1.9.5
"Termination" of the Statement of Work.

8. OPERATION AND MAINTENANCE

It is IBM's intent that the IBM sites will remain operational 24 hours a day, 7 
days a week.

IBM will use reasonable efforts to provide Splitrock beneficial use of IBM
Sites as outlined in this Statement of Work for the entire Term of the
Contract. Should this not occur, due to events caused by IBM, IBM will suspend
the Monthly Charges and obligations for the period when beneficial use is not
available.

9. INSURANCE

Throughout the Term, Splitrock shall maintain a policy of insurance covering
the Splitrock Equipment against loss, damage, or destruction caused by boiler
explosion, machine breakdown, fire and the perils specified in the standard
extended coverage endorsement, by vandalism and


                                      18
<PAGE>   21
malicious mischief, and by sprinkler, gas, water, steam and sewer
leakage. The amount of insurance shall equal one hundred percent
(100%) of the replacement cost of the Splitrock Equipment.

Splitrock hereby waives its right of recovery against IBM and releases IBM from
any claim arising out of loss, damage or destruction to the Splitrock Equipment
and contents thereon or therein whether or not such loss, damage or destruction
may be attributable to the fault or negligence of IBM or its agents, invitees,
contractors or employees. Such casualty insurance policy shall include a waiver
of the insurer's rights of subrogation against IBM not an insured under said
policy. Splitrock shall look solely to the proceeds of its casualty insurance
policy (and to its own funds to the extent it is self-insured) to compensate it
for any such loss, damage or destruction.

10. GENERAL

You may not assign this Contract without the specific written permission of
IBM. Any attempt to assign any of the rights, duties or obligations of this
Contract without such consent is void.

If there is a conflict between the terms and conditions of this Contract and
the Agreement this Contract will prevail.

THE PARTIES ACKNOWLEDGE THAT THEY HAVE READ THIS CONTRACT, UNDERSTAND IT, AND
AGREE TO BE BOUND BY ITS TERMS AND CONDITIONS. FURTHER, THEY AGREE THAT THE
COMPLETE AND EXCLUSIVE STATEMENT OF THE AGREEMENT BETWEEN THE PARTIES SHALL
CONSIST OF THIS CONTRACT, THE AGREEMENT, THE REFERENCED SOW, AND APPLICABLE
SUPPLEMENTS, INCLUDING THOSE EFFECTIVE IN THE FUTURE. THIS STATEMENT OF THE
AGREEMENT SUPERSEDES ALL OTHER PRIOR PROPOSALS, ORAL OR WRITTEN, AND ALL OTHER
COMMUNICATIONS BETWEEN THE PARTIES RELATING TO THIS SUBJECT.

                                PROMISSORY NOTE

$5,000,000.00                                                       June 1, 1998


         For value received, Splitrock Services, Inc. (hereinafter called
"Maker") promises and agrees to pay to the order of Linsang Partners, L.L.C.
(hereinafter called "Payee") at its offices at Landover, Maryland, in lawful
money of the United States of America the sum of five million dollars
($5,000,000.00) together with interest thereon from the date hereof until
maturity at a fixed rate of nine and three-fourths (9 3/4%) percent per annum.

         All past due principal and interest shall bear interest at a rate per
annum which is one percent (1%) per annum above the prematurity rate specified
above (but in no event to exceed the maximum rate of nonusurious interest
allowed from time to time by law as now, or to the extent allowed by law) from
maturity until paid. Unless otherwise provided, interest shall be computed on a
per annum basis of a year of 360 days and for the actual number of days
(including the first but excluding the last day) elapsed unless such
calculation would result in a usurious rate, in which case interest shall be
calculated on a per annum basis of a year of 365 or 366 days, as the case 
may be.

         This note is due and payable as follows to wit:

         Accrued interest payable on July 1, 1998 and continuing on the first
         (1st) day of each successive month thereafter until paid in full.
         Principal is due and payable upon third (30) days written demand, but
         if no demand is made, then not later than December 31, 2002.

         If any installment or payment of principal or interest of this note is
not paid when due; or if Maker becomes insolvent (however, such insolvency may
be evidenced); be dissolved, wound up, liquidated or otherwise terminated; at
the option of Payee, this note shall become and be due and payable forthwith
upon written demand following thirty (30) days notice of nonpayment or such
other event.

         Maker reserves the option of prepaying the principal of this note, in
whole or in part, at any time after the date hereof without penalty. At the
option of Payee, it may demand (at any time at or after prepayment) all accrued
and unpaid interest with respect to the principal amount prepaid through the
date of prepayment. All payments hereunder, whether designated as payments of
principal or interest, shall be applied to the principal or interest of this
note or to expenses provided for herein, or any combination of the foregoing,
as directed by Payee at its option.

Default, (iv) the date on which a registration statement with respect to the

herein and the Warrant Agent is willing to so act.

party and for the equal and ratable benefit of the Holders of Warrants:

                                   ARTICLE II

                              Warrant Certificates

                  SECTION 2.01. Form and Dating. Provisions relating to Warrants
are set forth in the Appendix, which is hereby incorporated in and expressly
made a part of this Warrant Agreement. The Warrant Certificates shall each be
substantially in the form of Exhibit A hereto, which is hereby incorporated in
and expressly made a part of this Warrant Agreement. The Warrant Certificates
may have notations, legends or endorsements required by law, stock exchange
rule, agreements to which the Company is subject, if any, or usage (provided

Certificate, the Warrant Certificate shall be valid nevertheless.

                  A Warrant shall not be valid until an authorized signatory of
the Warrant Agent manually countersigns the Warrant Certificate. The signature
shall be conclusive

                                                                               7

evidence that the Warrant has been authenticated under this Warrant Agreement.

                  The Warrant Agent shall countersign and make available for
delivery Warrant Certificates as set forth in the Appendix.

                  The Warrant Agent may appoint an agent reasonably acceptable
to the Company to countersign the Warrants. Any such appointment shall be
evidenced by an instrument signed by a Warrant Officer, a copy of which shall be
furnished to the Company. Unless limited by the terms of such appointment, an
agent of the Warrant Agent may countersign Warrants whenever the Warrant Agent
may do so. Each reference in this Warrant Agreement to countersigning by the
Warrant Agent includes countersigning by such agent.

                  SECTION 2.03. Warrant Registrar. The Company shall maintain an
office or agency where Warrants may be presented for registration of transfer,
exchange or exercise (the "Warrant Registrar"). The Warrant Registrar shall keep
a register of the Warrants and of their transfer, exchange or exercise. The
Company may have one or more coregistrars. The term Warrant Registrar includes
any coregistrars. The Company initially appoints the Warrant Agent as (i)
Warrant Registrar in connection with the Warrants and (ii) the Warrant Custodian
(as defined in the Appendix) with respect to the Global Warrants.

                  The Company shall enter into an appropriate agency agreement
with any Warrant Registrar not a party to this Warrant Agreement. The agreement
shall implement the provisions of this Warrant Agreement that relate to such
agent. The Company shall notify the Warrant Agent of the name and address of any
such agent. If the Company fails to maintain a Warrant Registrar, the Warrant
Agent shall act as such and shall be entitled to appropriate compensation
therefor pursuant to Section 6.05. The Company or any of its domestically
organized Wholly Owned Subsidiaries may act as Warrant Registrar.

                  The Company may remove any Warrant Registrar upon written
notice to such Warrant Registrar and to the Warrant Agent; provided, however,
that no such removal shall become effective until (1) acceptance of an
appointment by a successor as evidenced by an appropriate agreement entered into
by the Company and such successor Warrant Registrar and delivered to the Warrant
Agent or (2) notification to the Warrant Agent that the Warrant Agent shall
serve as Warrant Registrar until the appointment of a successor in accordance
with clause (1) above. The Warrant Registrar may resign at

                                                                               8

any time upon written notice; provided, however, that the Warrant Agent may
resign as Warrant Registrar only if the Warrant Agent also resigns as Warrant
Agent in accordance with Section 6.06. The Company and the Warrant Agent may
deem and treat the Person in whose name a Warrant Certificate is registered as
the absolute owner of such Warrant Certificate for all purposes whatsoever and
neither the Company nor the Warrant Agent shall be affected by notice to the
contrary.

                  SECTION 2.04. Warrantholder Lists. The Warrant Agent shall
preserve in as current a form as is reasonably practicable the most recent list
available to it of the names and addresses of Warrantholders. If the Warrant
Agent is not the Warrant Registrar, the Company shall furnish, or cause the
Warrant Registrar to furnish, to the Warrant Agent, at such times as the Warrant
Agent may request in writing, a list in such form and as of such date as the
Warrant Agent may reasonably require of the names and addresses of
Warrantholders.

                  SECTION 2.05. Transfer and Exchange. The Warrants shall be
issued in registered form and shall be transferable only upon the surrender of a
Warrant Certificate for registration of transfer and in compliance with the
Appendix. When a Warrant is presented to the Warrant Registrar with a request to
register a transfer, the Warrant Registrar shall register the transfer as
requested if the requirements of Section 8-401(a) of the Uniform Commercial Code
are met. When Warrants are presented to the Warrant Registrar with a request to
exchange them for an equal number of Warrants of other denominations, the
Warrant Registrar shall make the exchange as requested if the requirements of
Section 8-401(a)(1) and (2) of the Uniform Commercial Code are met. To permit
registration of transfers and exchanges, the Company shall execute and the
Warrant Agent shall countersign Warrant Certificates at the Warrant Registrar's
request. The Company may require payment of a sum sufficient to pay all taxes,
assessments or other governmental charges in connection with any transfer,
exchange or exercise pursuant to this Section 2.05.

                  Any Holder of a Global Warrant (as defined in the Appendix)
shall, by acceptance of such Global Warrant, agree that transfers of beneficial
interests in such Global Warrant may be effected only through a book-entry
system maintained by (i) the Holder of such Global Warrant (or its agent) or
(ii) any Holder of a beneficial interest in such Global Warrant, and that
ownership of a beneficial interest in such Global Warrant shall be required to
be reflected in a book entry.

                                                                               9

                  All Warrants issued upon any transfer or exchange pursuant to
the terms of this Warrant Agreement will evidence the same Warrants as the
Warrants surrendered upon such transfer or exchange.

                  SECTION 2.06. Replacement Certificate. If a mutilated Warrant
is surrendered to the Warrant Agent or if the Holder of a Warrant claims that
the Warrant Certificate has been lost, destroyed or wrongfully taken, the
Company shall execute and the Warrant Agent shall countersign a replacement
Warrant Certificate if the requirements of Section 8-405 of the Uniform
Commercial Code are met, such that the Holder (i) notifies the Company or the
Warrant Agent within a reasonable time after he has notice of such loss,
destruction or wrongful taking and the Warrant Agent does not register a
transfer prior to receiving such notification, (ii) makes such request to the
Company or the Warrant Agent prior to the Warrant being acquired by a protected
purchaser as defined in Section 8-303 of the Uniform Commercial Code (a
"protected purchaser") and (iii) satisfies any other reasonable requirements of
the Warrant Agent. If required by the Warrant Agent or the Company, such Holder
shall furnish an indemnity bond sufficient in the judgment of the Warrant Agent
to protect the Company and the Warrant Agent from any loss that either of them
may suffer if a Warrant is replaced. The Company and the Warrant Agent may
charge the Holder for their expenses in replacing a Warrant Certificate. Every
replacement Warrant is an additional obligation of the Company.

                  The provisions of this Section 2.06 are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement of mutilated, lost, destroyed or wrongfully taken Securities.

                  SECTION 2.07. Outstanding Warrants. Warrants outstanding at
any time are all Warrant Certificates executed by the Company and countersigned
by the Warrant Agent except for those canceled by it, those delivered to it for
cancelation and those described in this Section 2.07 as not outstanding. A
Warrant does not cease to be outstanding because an Affiliate of the Company
holds the Warrant. A Warrant ceases to be outstanding if the Company holds the
Warrant.

                  If a Warrant Certificate is replaced pursuant to Section 2.06,
it ceases to be outstanding unless the Warrant Agent and the Company receive
proof satisfactory to them that the replaced Warrant Certificate is held by a

                  SECTION 2.08. Temporary Warrants. In the event that Definitive
Warrants (as defined in the Appendix) are to be issued under the terms of this
Warrant Agreement, until such Definitive Warrants are ready for delivery, the
Company may prepare and the Warrant Agent shall countersign temporary Warrant
Certificates. Temporary Warrant Certificates shall be substantially in the form
of Definitive Warrants but may have variations that the Company considers
appropriate for temporary Warrants. Without unreasonable delay, the Company
shall prepare and the Warrant Agent shall countersign Definitive Warrants and
deliver them in exchange for temporary Warrant Certificates upon surrender of
such temporary Warrant Certificates.

                  SECTION 2.09. Cancelation. The Company at any time may deliver
Warrant Certificates to the Warrant Agent for cancelation. The Warrant Agent and
no one else shall cancel all Warrant Certificates surrendered for registration
of transfer, exchange, exercise or cancelation and deliver canceled Warrant
Certificates to the Company pursuant to written direction by an Officer. The
Company may not issue new Warrant Certificates to replace Warrants Certificates
that have been exercised or Warrants which the Company has purchased or
otherwise acquired. The Warrant Agent shall not countersign Warrant Certificates
to replace canceled Warrant Certificates other than pursuant to the terms of
this Warrant Agreement.

                  SECTION 2.10. CUSIP Numbers. The Company in issuing the
Warrants may use "CUSIP" numbers (if then generally in use) and, if so, the
Warrant Agent shall also use "CUSIP" numbers in notices to Holders; provided,
however, that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Warrant Certificates or as
contained in any notice and that reliance may be placed only on the other
identification numbers printed on the Warrant Certificates, and any such notice
shall not be affected by any defect in or omission of such numbers.

                                 Exercise Terms

                  SECTION 3.01. Exercise. Each Warrant shall initially entitle
the Holder thereof, subject to adjustment pursuant to the terms of this Warrant
Agreement, to purchase 10.124954 shares of Common Stock. The exercise price (the
"Exercise Price") of each Warrant is $.01 per share.

                                                                              11

                  SECTION 3.02. Exercise Periods. (a) Subject to the terms and
conditions set forth herein, the Warrants shall be exercisable at any time and
from time to time on any Business Day after the first anniversary of the Issue
Date; provided, however, that holders of Warrants will be able to exercise their
Warrants only if (i) the Common Shelf Registration Statement relating to the
Warrant Shares is effective or (ii) the exercise of such Warrants is exempt from
the registration requirements of the Securities Act, and the Warrant Shares are
qualified for sale or exempt from qualification under the applicable securities
laws of the states or other jurisdictions in which such Holders reside.

                  (b) No Warrant shall be exercisable after July 15, 2008 (the
"Expiration Date").

                  SECTION 3.03. Expiration. A Warrant shall terminate and become
void as of the earlier of (i) the close of business on the Expiration Date or
(ii) the date such Warrant is exercised. The Company shall give notice not less
than 90, and not more than 120, days prior to the Expiration Date to the Holders
of all then outstanding Warrants to the effect that the Warrants will terminate
and become void as of the close of business on the Expiration Date; provided,
however, that if the Company fails to give notice as provided in this Section
3.03, the Warrants will nevertheless expire and become void on the Expiration
Date.

                  SECTION 3.04. Manner of Exercise. Warrants may be exercised
upon (i) surrender to the Warrant Agent at the office of the Warrant Agent of
the related Warrant Certificate, together with the form of election attached
thereto to purchase Common Stock on the reverse thereof duly filled in and
signed by the Holder thereof and (ii) payment to the Warrant Agent, for the
account of the Company, of the Exercise Price for each Warrant Share or other
security issuable upon the exercise of such Warrants then exercised. Such
payment shall be made (i) in cash or by certified or official bank check payable
to the order of the Company or by wire transfer of funds to an account
designated by the Company for such purpose or (ii) without the payment of cash,
by reducing the number of shares of Common Stock obtainable upon the exercise of
a Warrant and payment of the Exercise Price in cash so as to yield a number of
shares of Common Stock upon the exercise of such Warrant equal to the product of
(a) the number of shares of Common Stock issuable as of the Exercise Date upon
the exercise of such Warrant (if payment of the Exercise Price were being made
in cash) and (b) the Cashless Exercise Ratio. An exercise of a Warrant in
accordance with the immediately preceding clause (ii) is herein called a
"Cashless Exercise". Upon surrender



<PAGE>   16



                                                                              12

of a Warrant Certificate representing more than one Warrant in connection with
the Holder's option to elect a Cashless Exercise, the number of shares of Common
Stock deliverable upon a Cashless Exercise shall be equal to the number of
shares of Common Stock issuable upon the exercise of Warrants that the holder
specifies are to be exercised pursuant to a Cashless Exercise multiplied by the
Cashless Exercise Ratio. All provisions of this Warrant Agreement shall be
applicable with respect to a surrender of a Warrant Certificate pursuant to a
Cashless Exercise for less than the full number of Warrants represented thereby.
Subject to Section 3.02, the rights represented by the Warrants shall be
exercisable at the election of the Holders thereof either in full at any time or
from time to time in part and in the event that a Warrant Certificate is
surrendered for exercise of less than all the Warrants represented by such
Warrant Certificate at any time prior to the Expiration Date, a new Warrant
Certificate representing the remaining Warrants shall be issued. The Warrant
Agent shall countersign and deliver the required new Warrant Certificates, and
the Company, at the Warrant Agent's request, shall supply the Warrant Agent with
Warrant Certificates duly signed on behalf of the Company for such purpose.

                  SECTION 3.05. Issuance of Warrant Shares. Subject to Section
2.06, upon the surrender of Warrant Certificates and payment of the per share
Exercise Price or election of a Cashless Exercise, as set forth in Section 3.04,
the Warrant Agent shall requisition from the Company, and the Company shall
issue and, if appointed, cause the transfer agent for the Common Stock ("Stock
Transfer Agent") to countersign and deliver to or upon the written order of the
Holder and in such name or names as the Holder may designate, a certificate or
certificates for the number of full Warrant Shares so purchased upon the
exercise of such Warrants or other securities or property to which it is
entitled, registered or otherwise, to the Person or Persons entitled to receive
the same (including any depositary institution so designated by a Holder),
together with cash as provided in Section 3.06 in respect of any fractional
Warrant Shares otherwise issuable upon such exercise. Such certificate or
certificates shall be deemed to have been issued and any Person so designated to
be named therein shall be deemed to have become a holder of record of such
Warrant Shares as of the date of the surrender of such Warrant Certificates and
payment of the per share Exercise Price or election of a Cashless Exercise, as
aforesaid; provided, however, that if, at such date, the transfer books for the
Warrant Shares shall be closed, the certificates for the Warrant Shares in
respect of which such Warrants are then exercised shall be issuable as of the
date on which



<PAGE>   17



                                                                              13

such books shall next be opened and until such date the Company shall be under
no duty to deliver any certificates for such Warrant Shares; provided further,
however, that such transfer books, unless otherwise required by law, shall not
be closed at any one time for a period longer than 20 calendar days.

                  SECTION 3.06. Fractional Warrant Shares. The Company shall not
be required to issue fractional Warrant Shares on the exercise of Warrants. If
more than one Warrant shall be exercised in full at the same time by the same
Holder, the number of full Warrant Shares which shall be issuable upon such
exercise shall be computed on the basis of the aggregate number of Warrant
Shares which may be purchasable pursuant thereto. If any fraction of a Warrant
Share would, except for the provisions of this Section 3.06, be issuable upon
the exercise of any Warrant (or specified portion thereof), the Company shall
pay an amount in cash equal to the Current Market Value per Warrant Share, as
determined on the day immediately preceding the date the Warrant is presented
for exercise, multiplied by such fraction, computed to the nearest whole cent.

                  SECTION 3.07. Reservation of Warrant Shares. The Company
shall at all times keep reserved out of its authorized shares of Common Stock a
number of shares of Common Stock sufficient to provide for the exercise of all
outstanding Warrants. The registrar for the Common Stock (the "Stock Registrar")
shall at all times until the Expiration Date reserve such number of authorized
shares as shall be required for such purpose. The Company will keep a copy of
this Warrant Agreement on file with the Stock Transfer Agent if such Stock
Transfer Agent is appointed. The Company will supply such Stock Transfer Agent,
if appointed, with duly executed stock certificates for such purpose and will
itself provide or otherwise make available any cash which may be payable as
provided in Section 3.06. The Company will furnish to such Stock Transfer Agent,
if appointed, a copy of all notices of adjustments (and certificates related
thereto) transmitted to each Holder.

                  Before taking any action which would cause an adjustment
pursuant to Article IV to reduce the Exercise Price below the then par value (if
any) of the Common Stock, the Company shall take any and all corporate action
which may, in the opinion of counsel, be necessary in order that the Company may
validly and legally issue fully paid and nonassessable shares of Common Stock at
the Exercise Price as so adjusted.




<PAGE>   18



                                                                              14

                  The Company covenants that all Warrant Shares which may be
issued upon exercise of Warrants shall, upon issue, be fully paid,
nonassessable, free of preemptive rights, free from all taxes and free from all
liens, charges and security interests with respect to the issue thereof.

                  SECTION 3.08. Compliance with Law. (a) Notwithstanding
anything in this Warrant Agreement to the contrary, in no event shall a Holder
be entitled to exercise a Warrant unless (i) a registration statement filed
under the Securities Act in respect of the issuance of the Warrant Shares is
then effective or (ii) in the opinion of counsel the exercise of such Warrants
is exempt from the registration requirements of the Securities Act and such
securities are qualified for sale or exempt from qualification under the
applicable securities laws of the states or other jurisdictions in which such
Holders reside.

                  (b) If any shares of Common Stock required to be reserved for
purposes of the exercise of Warrants require, under any other Federal or state
law or applicable governing rule or regulation of any national securities
exchange, registration with or approval of any governmental authority, or
listing on any such national securities exchange before such shares may be
issued upon exercise, the Company will use its best efforts to cause such shares
to be duly registered or approved by such governmental authority or listed on
the relevant national securities exchange, as the case may be.


                                   ARTICLE IV

                             Antidilution Provisions

                  SECTION 4.01. Changes in Common Stock. In the event that at
any time and from time to time the Company shall (i) pay a dividend or make a
distribution on the Common Stock in shares of Common Stock or other shares of
Capital Stock, (ii) subdivide its outstanding shares of Common Stock into a
larger number of shares of Common Stock, (iii) combine its outstanding shares of
Common Stock into a smaller number of shares of Common Stock or (iv) increase or
decrease the number of shares of Common Stock outstanding by reclassification of
its Common Stock, then the number of shares of Common Stock issuable upon
exercise of each Warrant immediately after the happening of such event shall be
adjusted so that, after giving effect to such adjustment, the Holder of each
Warrant shall be entitled to receive the number of shares of Common Stock upon
exercise of such Warrant that such Holder would have owned or have been



<PAGE>   19



                                                                              15

entitled to receive had such Warrants been exercised immediately prior to the
happening of the events described above (or, in the case of a dividend or
distribution of Common Stock, immediately prior to the record date there for).
An adjustment made pursuant to this Section 4.01 shall become effective
immediately after the distribution date, retroactive to the record date therefor
in the case of a dividend or distribution in shares of Common Stock or other
shares of Capital Stock, and shall become effective immediately after the
effective date in the case of a sub division, combination or reclassification.

                  SECTION 4.02. Cash Dividends and Other Distributions. In the
event that at any time and from time to time the Company shall distribute to all
holders of Common Stock (i) any dividend or other distribution (including any
dividend or distribution made in connection with a consolidation or merger in
which the Company is the continuing corporation) of cash, evidences of its
indebtedness, shares of its Capital Stock or any other properties or securities
or (ii) any options, warrants or other rights to subscribe for, purchase, or
which are convertible into, any of the foregoing (other than, in the case of
clause (i) and (ii) above, (A) any dividend or distribution described in Section
4.01, (B) any rights, options, warrants or securities described in Section 4.03
or Section 4.04 and (C) any cash dividends or other cash distributions from
current or retained earnings other than Extraordinary Cash Dividends), then the
number of shares of Common Stock issuable upon the exercise of each Warrant
immediately prior to such record date for any such dividend or distribution
shall be increased to a number determined by multiplying the number of shares of
Common Stock issuable upon the exercise of such Warrant immediately prior to
such record date for any such dividend or distribution by a fraction, the
numerator of which shall be the Current Market Value per share of Common Stock
on the record date for such dividend or distribution, and the denominator of
which shall be such Current Market Value per share of Common Stock less the sum
of (x) the amount of cash, if any, distributed per share of Common Stock and (y)
the then fair value (as determined in good faith by the Board of Directors,
whose determination shall be evidenced by a board resolution filed with the
Warrant Agent, a copy of which will be sent to Holders upon request) of the
portion, if any, of the distribution applicable to one share of Common Stock
consisting of evidences of indebtedness, shares of stock, securities, other
property, warrants, options or subscription or purchase rights; and subject to
Section 4.08, the Exercise Price shall be adjusted to a number determined by
dividing the Exercise Price immediately prior to such record




<PAGE>   20



                                                                              16

date by the above fraction. Such adjustments shall be made, and shall only
become effective, whenever any dividend or distribution to which this Section
4.02 applies is made; provided, however, that the Company is not required to
make an adjustment pursuant to this Section 4.02 if at the time of such
distribution the Company makes the same distribution to Holders of Warrants as
it makes to holders of Common Stock pro rata based on the number of shares of
Common Stock for which such Warrants are exercisable (whether or not currently
exercisable). No adjustment shall be made pursuant to this Section 4.02 which
shall have the effect of decreasing the number of shares of Common Stock
issuable upon exercise of each Warrant or increasing the Exercise Price.

                  SECTION 4.03. Common Stock Issue. In the event that at any
time or from time to time the Company shall issue shares of Common Stock for a
consideration per share that is less than the Current Market Value per share of
Common Stock as of the issuance date of such shares, the number of shares of
Common Stock issuable upon the exercise of each Warrant immediately after such
issuance date shall be determined by multiplying the number of shares of Common
Stock issuable upon exercise of each Warrant immediately prior to such issuance
date by a fraction, the numerator of which shall be the number of shares of
Common Stock out standing immediately preceding the issuance of such shares plus
the number of additional shares of Common Stock to be issued in such
transaction, and the denominator of which shall be the number of shares of
Common Stock outstanding immediately preceding the date for the issuance of such
shares plus the total number of shares of Common Stock which the aggregate
consideration expected to be received by the Company upon the issuance of such
shares (as determined in good faith by the Board of Directors, whose
determination shall be evidenced by a board resolution filed with the Warrant
Agent, a copy of which will be sent to Holders upon request) would purchase at
the Current Market Value per share of Common Stock as of the date of such
issuance; and, subject to Section 4.08, in the event of any such adjustment, the
Exercise Price shall be adjusted to a number determined by dividing the Exercise
Price immediately prior to such date of issuance by the aforementioned fraction;
provided, however, that no adjustment to the number of Warrant Shares issuable
upon the exercise of the Warrants or to the Exercise Price shall be made as a
result of (i) the issuance of shares of Common Stock in bona fide public
offerings that are underwritten or in which a placement agent is retained by the
Company, (ii) the issuance of shares of Common Stock (including upon exercise of
options) pursuant to the terms of and in order to give effect to the



<PAGE>   21




                                                                              17

1997 Incentive Share Plan (as defined in the Offering Memorandum) in an amount
of up to 10% (calculated giving effect to all issuances of such options since
the date hereof) of the fully diluted shares of Common Stock, or such greater
amount (calculated giving effect to all issuances of such options since the date
hereof) as is approved by a majority of the disinterested members of the Board
of Directors, and (iii) the issuance of shares of Common Stock in connection
with acquisitions of products and businesses other than to Affiliates of the
Company. Such adjustment shall be made, and shall only become effective,
whenever such shares are issued. No adjustment shall be made pursuant to this
Section 4.03 which shall have the effect of decreasing the number of shares of
Common Stock issuable upon exercise of each Warrant or increasing the Exercise
Price.

                   SECTION 4.04. Issuance of Rights or Options. In the event
that at any time or from time to time the Company shall issue to holders of
Common Stock (i) rights, options or warrants to acquire (provided, however, that
no adjustment shall be made under Section 4.03 or 4.04 upon the exercise of such
rights, options or warrants), or (ii) securities convertible or exchangeable
into (provided, however, that no adjustment shall be made under Section 4.03 or
4.04 upon the conversion or exchange of such securities (other than issuances
specified in (i) or (ii) which are made as the result of anti-dilution
adjustments in such securities)), Common Stock entitling the holders thereof to
subscribe for or purchase shares of Common Stock at a price per share that is
less than the Current Market Value per share of Common Stock in effect
immediately prior to such issuance other than in connection with the adoption of
a shareholder rights plan by the Company, the number of shares of Common Stock
issuable upon the exercise of each Warrant immediately after such issuance shall
be determined by multiplying the number of shares of Common Stock issuable upon
exercise of each Warrant immediately prior to such issuance by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to the issuance of such rights, options, warrants or
securities plus the number of additional shares of Common Stock offered for
subscription or purchase or into which such securities are convertible or
exchangeable, and the denominator of which shall be the number of shares of
Common Stock outstanding immediately prior to the issuance of such rights,
options, warrants or securities plus the total number of shares of Common Stock
which the aggregate consideration expected to be received by the Company upon
the exercise, conversion or exchange of such rights, options, warrants or
securities (as determined in good faith by the Board, whose determination shall
be evidenced by a board resolution filed with the Warrant Agent, a copy of which
will be sent to Holders upon request) would purchase at the Current Market Value
per share of Common Stock as of the record date; and, subject to Section 4.08,
in the event of any such adjustment, the Exercise Price shall be adjusted to 



<PAGE>   22

                                                                              18

a number determined by dividing the Exercise Price immediately prior to such
date of issuance by the afore mentioned fraction; provided, however, that no
adjustment to the number of Warrant Shares issuable upon the exercise of the
Warrants or to the Exercise Price shall be made as a result of the issuance of
options to acquire additional shares of Common Stock pursuant to the terms of
and in order to give effect to the 1997 Incentive Share Plan (as defined in the
Offering Memorandum) in an amount of up to 10% (calculated giving effect to all
issuances of such options since the date hereof) of the fully diluted shares of
Common Stock, or such greater amount (calculated giving effect to all issuances
of such options since the date hereof) as is approved by a majority of the
disinterested members of the Board of Directors. Such adjustment shall be made,
and shall only become effective, whenever such rights, options, warrants or
securities are issued. No adjustment shall be made pursuant to this Section 4.04
which shall have the effect of decreasing the number of shares of Common Stock
issuable upon exercise of each Warrant or increasing the Exercise Price.

                  SECTION 4.05. Combination; Liquidation. (a) Except as provided
in Section 4.05(b), in the event of a Combination, each Holder shall have the
right to receive upon exercise of the Warrants the kind and amount of shares of
Capital Stock or other securities or property which such Holder would have been
entitled to receive upon completion of or as a result of such Combination had
such Warrant been exercised immediately prior to such event or to the relevant
record date for any such entitlement. Unless paragraph (b) is applicable to a
Combination, the Company shall provide, and deliver to the Warrant Agent, an
Opinion of Counsel to the effect that the surviving or acquiring Person (the
"Successor Company") in such Combination will enter into an agreement with the
Warrant Agent confirming the Holders' rights pursuant to this Section 4.05(a)
and providing for adjustments, which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article IV. The provisions
of this Section 4.05(a) shall similarly apply to successive Combinations
involving any Successor Company.

                  (b) In the event of (i) a Combination where consideration to
the holders of Common Stock in exchange for their shares is payable solely in
cash or (ii) the dissolution, liquidation or winding-up of the Company, the
Holders of the Warrants shall be entitled to receive, upon surrender of their
Warrant Certificates, such cash distributions on an equal basis with the holders
of Common Stock or other securities issuable upon exercise of the Warrants, as
if the Warrants had been exercised immediately prior to such event, less the
Exercise Price.

                  In the event of any Combination described in this Section
4.05(b), the surviving or acquiring Person and, in 


<PAGE>   23


                                                                              19

the event of any dissolution, liquidation or winding-up of the Company, the
Company, shall deposit promptly with the Warrant Agent the funds, if any,
necessary to pay the Holders of the Warrants the amounts to which they are
entitled as described above. After such funds and the surrendered Warrant
Certificates are received, the Warrant Agent shall make payment to the Holders
by delivering a check in such amount as is appropriate (or, in the case of
consideration other than cash, such other consideration as is appropriate) to
such Person or Persons as it may be directed in writing by the Holders
surrendering such Warrants.

                  SECTION 4.06. Other Events. If any event occurs as to which
the foregoing provisions of this Article IV are not strictly applicable or, if
strictly applicable, would not, in the good faith judgment of the Board of
Directors, fairly and adequately protect the purchase rights of the Warrants in
accordance with the essential intent and principles of such provisions, then
such Board of Directors shall make such adjustments in the application of such
provisions, in accordance with such essential intent and principles, as shall be
reasonably necessary, in the good faith opinion of such Board of Directors, to
protect such purchase rights as aforesaid, but in no event shall any such
adjustment have the effect of increasing the Exercise Price or decreasing the
number of shares of Common Stock issuable upon exercise of the Warrants.

                  SECTION 4.07. Superseding Adjustment. Upon the expiration of
any rights, options, warrants or conversion or exchange privileges which
resulted in adjustments pursuant to this Article IV, if any thereof shall not
have been exercised, the number of Warrant Shares issuable upon the exercise of
each Warrant shall be readjusted pursuant to the applicable section of Article
IV as if (i) the only shares of Common Stock issuable upon exercise of such
rights, options, warrants, conversion or exchange privileges were the shares of
Common Stock, if any, actually issued upon the exercise of such rights, options,
warrants or conversion or exchange privileges and (ii) shares of Common Stock
actually issued, if any, were issuable for the consideration actually received
by the Company upon such exercise plus the aggregate consideration, if any,
actually received by the Company for the issuance, sale or grant of all such
rights, options, warrants or conversion or exchange privileges whether or not
exercised and the Exercise Price shall be readjusted inversely; provided,
however, that no such readjustment (except by reason of an intervening
adjustment under Section 4.01) shall have the effect of decreasing the number of
Warrant Shares issuable upon the exercise of each

<PAGE>   24

                                                                              20


Warrant or increasing the Exercise Price by an amount in excess of the amount of
the adjustment initially made in respect of the issuance, sale or grant of such
rights, options, warrants or conversion or exchange privileges.

                 SECTION 4.08. Minimum Adjustment. The adjustments required by
the preceding sections of this Article IV shall be made whenever and as often as
any specified event requiring an adjustment shall occur, except that no
adjustment of the Exercise Price or the number of shares of Common Stock
issuable upon exercise of the Warrants that would otherwise be required shall be
made unless and until such adjustment either by itself or with other adjustments
not previously made increases or decreases by at least 1% the Exercise Price or
the number of shares of Common Stock issuable upon exercise of the Warrants
immediately prior to the making of such adjustment. Any adjustment representing
a change of less than such minimum amount shall be carried forward and made as
soon as such adjustment, together with other adjustments required by this
Article IV and not previously made, would result in a minimum adjustment. For
the purpose of any adjustment, any specified event shall be deemed to have
occurred at the close of business on the date of its occurrence. In computing
adjustments under this Article IV, fractional interests in Common Stock shall be
taken into account to the nearest one-hundredth of a share.

                  SECTION 4.09. Notice of Adjustment. Whenever the Exercise
Price or the number of shares of Common Stock and other property, if any,
issuable upon exercise of the Warrants is adjusted, as herein provided, the
Company shall deliver to the Warrant Agent a certificate of a firm of
independent accountants selected by the Board of Directors (who may be the
regular accountants employed by the Company) setting forth, in reasonable
detail, the event requiring the adjustment and the method by which such
adjustment was calculated (including a description of the basis on which (i) the
Board of Directors determined the then fair value of any evidences of
indebtedness, other securities or property or warrants, options or other
subscription or purchase rights and (ii) the Current Market Value of the Common
Stock was determined, if either of such determinations were required), and
specifying the Exercise Price and the number of shares of Common Stock issuable
upon exercise of the Warrants after giving effect to such adjustment. The
Company shall promptly cause the Warrant Agent to mail a copy of such
certificate to each Holder in accordance with Section 7.05. The Warrant Agent
shall be entitled to rely on such certificate and shall be under no duty or
responsibility with respect to any such certificate, except to exhibit the same
from time to time, to any Holder desiring

                                                                              21
an inspection thereof during reasonable business hours. The Warrant Agent
shall not at any time be under any duty or responsibility to any Holder to
determine whether any facts exist which may require any adjustment of the
Exercise Price or the number of shares of Common Stock or other stock or
property issuable on exercise of the Warrants, or with respect to the nature or
extent of any such adjustment when made, or with respect to the method employed
in making such adjustment or the validity or value of any shares of Common
Stock, evidences of indebtedness, warrants, options, or other securities or
property.

                  SECTION 4.10. Notice of Certain Transactions. In the event
that the Company shall propose to (a) pay any dividend payable in securities of
any class to the holders of its Common Stock or to make any other non-cash
dividend or distribution to the holders of its Common Stock, (b) offer the
holders of its Common Stock rights to subscribe for or to purchase any
securities convertible into shares of Common Stock or shares of stock of any
class or any other securities, rights or options, (c) issue any (i) shares of
Common Stock, (ii) rights, options or warrants entitling the holders thereof to
subscribe for shares of Common Stock or (iii) securities convertible into or
exchangeable or exercisable for Common Stock (in the case of (i), (ii) and
(iii), if such issuance or adjustment would result in an adjustment hereunder),
(d) effect any capital reorganization, reclassification, consolidation or
merger, (e) effect the voluntary or involuntary dissolution, liquidation or
winding-up of the Company or (f) make a tender offer or exchange offer with
respect to the Common Stock, the Company shall within five days after any such
action or offer send to the Warrant Agent a notice and the Warrant Agent shall
within five days after receipt thereof send the Holders a notice (in such form
as shall be furnished to the Warrant Agent by the Company) of such proposed
action or offer. Such notice shall be mailed by the Warrant Agent to the Holders
at their addresses as they appear in the books of the Warrant Registrar, which
shall specify the record date for the purposes of such dividend, distribution or
rights, or the date such issuance or event is to take place and the date of
participation therein by the holders of Common Stock, if any such date is to be
fixed, and shall briefly indicate the effect, if any, of such action on the
Common Stock and on the number and kind of any other shares of stock and on
other property, if any, and the number of shares of Common Stock and other
property, if any, issuable upon exercise of each Warrant and the Exercise Price
after giving effect to any adjustment pursuant to Article IV which will be
required as a result of such action. Such notice shall be given as promptly as

<PAGE>   26

                                                                              22
possible and (x) in the case of any action covered by clause (a) or (b) above,
at least 10 days prior to the record date for determining holders of the Common
Stock for purposes of such action or (y) in the case of any other such action,
at least 20 days prior to the date of the taking of such proposed action or the
date of participation therein by the holders of Common Stock, whichever shall be
the earlier.

                  SECTION 4.11. Adjustment to Warrant Certificate. The form of
Warrant Certificate need not be changed because of any adjustment made pursuant
to this Article IV, and Warrant Certificates issued after such adjustment may
state the same Exercise Price and the same number of shares of Common Stock
issuable upon exercise of the Warrants as are stated in the Warrant Certificates
initially issued pursuant to this Warrant Agreement. The Company, however, may
at any time in its sole discretion make any change in the form of Warrant
Certificate that it may deem appropriate to give effect to such adjustments and
that does not affect the substance of the Warrant Certificate, and any Warrant
Certificate thereafter issued or countersigned, whether in exchange or
substitution for an outstanding Warrant Certificate or otherwise, may be in the
form as so changed.


                                    ARTICLE V

                      Registration Rights; Indemnification

                  SECTION 5.01. Effectiveness of Registration Statement. Subject
to Section 5.02, the Company shall cause to be filed pursuant to Rule 415 (or
any successor provision) of the Securities Act not later than 45 days after the
Issue Date, a shelf registration statement relating to the offer and sale of the
Warrants by the Holders from time to time in accordance with the methods of
distribution elected by such holders and set forth in such registration
statement (the "Warrant Shelf Registration Statement"), and shall use its best
efforts to cause the Warrant Shelf Registration Statement to be declared
effective under the Securities Act on or before 105 days after the Issue Date,
and shall cause to be filed a shelf registration statement covering the issuance
of Warrant Shares to the Holders upon exercise of the Warrants by the Holders
thereof (the "Common Shelf Registration Statement", and together with the
Warrant Shelf Registration Statement, the "Registration Statements") and shall
use its best efforts to cause the Common Shelf Registration Statement to be
declared effective on or before 365 days after the Issue Date. The Company shall
use its best efforts to cause (a) the Warrant Shelf Registration Statement to
remain

<PAGE>   27
                                                                              23
continuously effective until the earliest of (i) such time as all Warrants
have been sold thereunder, (ii) two years after its effective date and (iii)
until all Warrants can be sold without restriction under the Securities Act and
(b) the Common Shelf Registration Statement to remain continuously effective
until the earlier of (i) such time as all Warrants have been exercised and (ii)
the Expiration Date. In connection with any Registration Statement, (i) the
Company shall furnish to the Warrant Agent and the Initial Purchaser, prior to
the filing with the Commission, a copy of any Registration Statement, and each
amendment thereof and each amendment or supplement, if any, to the prospectus
included therein and shall use its reasonable best efforts to reflect in each
such document, when filed with the Commission, such comments as the Warrant
Agent or the Initial Purchaser may reasonably propose, (ii) the Company shall
furnish to each Holder, without charge, at least one conformed copy of any
Registration Statement and any post-effective amendment thereto, including
financial statements and schedules, and, if the Holder so requests in writing,
all exhibits thereto (including those incorporated by reference), (iii) the
Company shall, for so long as any Registration Statement is effective, deliver
to each Holder and the Initial Purchaser, without charge, as many copies of the
prospectus (including each preliminary prospectus) included in such Registration
Statement and any amendment or supplement thereto as such Holder or Initial
Purchaser may reasonably request, and the Company consents to the proper use of
the prospectus therein and any amendment or supplement thereto by each of the
selling Holders in connection with the offering and sale of the Warrants or the
exercise, offering or sale of Warrant Shares, as the case may be, covered by
such prospectus and any amendment or supplement thereto, (iv) the Company may
require each Holder of Warrants to be sold pursuant to the Warrant Shelf
Registration Statement or to be exercised in connection with the Common Shelf
Registration Statement to furnish to the Company such information regarding the
Holder and the distribution of such Warrants or Warrant Shares as the Company
may from time to time reasonably request for inclusion in such Registration
Statement (the "Holders' Information"), and the Company may exclude from such
registration the Transfer Restricted Warrants (as defined in the Appendix) of
any Holder that fails to furnish such information within a reasonable time after
receiving such request, (v) the Company shall, if requested, promptly
incorporate in a prospectus supplement or post-effective amendment to such
Registration Statement such information as a majority in interest of the Holders
reasonably agree should be included therein and shall make all required filings
of such prospectus supplement or post-effective 

<PAGE>   28

                                                                              24
amendment as soon as practicable following notification of the matters to be
incorporated in such prospectus supplement or post-effective amendment, (vi) the
Company shall enter into such agreements (including underwriting agreements) as
are appropriate, customary and reasonably necessary in connection with any such
Registration Statement and (vii) the Company shall (A) make reasonably available
for inspection by a representative of, and counsel acting for Holders of a
majority of the Warrants and any underwriter participating in any disposition of
Warrants, all relevant financial and other records, pertinent corporate
documents and properties of the Company, (B) use its reasonable best efforts to
have its officers, directors, employees, accountants and counsel supply all
relevant information reasonably requested by such representative, counsel or any
such underwriter in connection with such Registration Statement, and (C) if
requested by Holders of a majority of Warrants, their counsel or the managing
underwriters (if any) in connection with such Registration Statement, use its
reasonable best efforts to cause (x) its counsel to deliver an opinion relating
to the Registration Statement and the Warrants or Warrant Shares, as the case
may be, in customary form, (y) its officers to execute and deliver all customary
documents and certificates requested by Holders of a majority of the Warrants,
their counsel or the managing underwriters (if any) and (z) its independent
public accountants to provide a comfort letter or letters in customary form,
subject to receipt of appropriate documentation as contemplated, and only if
permitted, by Statement of Auditing Standards No. 72.

                  (b) The Company shall notify Holders and, if requested,
confirm in writing (which notice pursuant to clauses (ii)-(v) hereof shall be
accompanied by an instruction to suspend the use of the prospectus until the
requisite changes have been made): (i) when any Registration Statement and any
amendment thereto has been filed with the Commission and when such Registration
Statement or any post-effective amendment thereto has become effective; (ii) of
any request by the Commission for amendments or supplements to any Registration
Statement or the prospectus included therein or for additional information;
(iii) of the issuance by the Commission of any stop order suspending the
effectiveness of any Registration Statement or the initiation of any proceedings
for that purpose; (iv) of the receipt by the Company of any notification with
respect to the suspension of the qualification of the Warrants or the Warrant
Shares for sale in any jurisdiction or the initiation or threatening of any
proceeding for such purpose; and (v) of the happening of any event that requires
the making of any changes in any 


<PAGE>   29
                                                                              25
Registration Statement or the prospectus included therein in order that the
statements therein are not misleading and do not omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading. The Company shall make every reasonable effort to obtain the
withdrawal at the earliest possible time of any order suspending the
effectiveness of any Registration Statement. If any event contemplated by
clauses (ii) through (v) occurs during the period for which the Company is
required to maintain an effective Registration Statement, the Company shall
promptly prepare and file with the Commission a post-effective amendment to the
Registration Statement or a supplement to the related prospectus or file any
other required document so that, as thereafter delivered, the prospectus shall
not include an untrue statement of a material fact or omit to state a material
fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading. Each Holder agrees
that, upon receipt of any notice from the Company pursuant to clauses (ii)
through (v), such Holder shall discontinue disposition of such Warrants or
Warrant Shares until such Holder's receipt of copies of a supplemental or
amended prospectus or until advised in writing (the "Advice") by the Company
that the use of the applicable prospectus may be resumed. If the Company shall
give any notice under clauses (ii) through (v) during the period that the
Company is required to maintain an effective Registration Statement (the
"Effectiveness Period"), such Effectiveness Period, in the case of the Warrant
Shelf Registration Statement, shall be extended by the number of days during
such period from and including the date of the giving of such notice to and
including the date when each seller of Warrants or Warrant Shares covered by
such Registration Statement shall have received (x) the copies of a supplemental
or amended prospectus (if an amended or supplemental prospectus is required) or
(y) the Advice (if no amended or supplemental prospectus is required).

                  SECTION 5.02. Suspension. During any consecutive 365-day
period, the Company shall be entitled to suspend the availability of each of the
Warrant Shelf Registration Statement and the Common Shelf Registration Statement
for up to two 45 consecutive-day periods (except for the 45 consecutive-day
period immediately prior to the Expiration Date) if the Company's Board
determines in the exercise of its reasonable judgment that there is a valid
business purpose for such suspension and provides notice that such determination
was made to the Holders of the Warrants; provided, however, that in no event
shall the Company be required to disclose the business purpose for such


<PAGE>   30

                                                                              26
suspension if the Company determines in good faith that such business purpose
must remain confidential.

                  SECTION 5.03. Blue Sky. The Company shall use its best efforts
to register or qualify the Warrants and the Warrant Shares under all applicable
securities laws, blue sky laws or similar laws of all jurisdictions in the
United States and Canada in which any holder of Warrants may or may be deemed to
purchase Warrants or Warrant Shares upon the exercise of Warrants and shall use
its best efforts to maintain such registration or qualification for so long as
it is required to cause the Warrant Shelf Registration Statement (in the case of
the Warrants) and the Common Shelf Registration Statement (in the case of the
Warrant Shares) to remain effective under the Securities Act pursuant to Section
5.01; provided, however, that the Company shall not be required to qualify
generally to do business in any jurisdiction where it would not otherwise be
required to qualify but for this Section 5.03 or to take any action which would
subject it to general service of process or to taxation in any such jurisdiction
where it is not then so subject.

                  SECTION 5.04. Accuracy of Disclosure. The Company represents
and warrants to each Holder and agrees for the benefit of each Holder that (i)
each of the Warrant Shelf Registration Statement and the Common Shelf
Registration Statement and any amendment thereto will not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements contained therein not
misleading and (ii) each of the prospectus furnished to such Holder for delivery
in connection with the sale of Warrants and the prospectus delivered to such
Holder upon the exercise of Warrants and the documents incorporated by reference
therein will not contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements contained therein, in light of the circumstances under which
they were made, not misleading; provided, however, that the Company shall have
no liability under clauses (i) or (ii) of this Section 5.04 with respect to any
such untrue statement or omission made in any Registration Statement in reliance
upon and in conformity with information furnished to the Company by or on behalf
of the Holders specifically for inclusion therein.

                  SECTION 5.05. Indemnification. (a) In connection with any
Registration Statement, the Company shall indemnify and hold harmless each
Holder (including, without limitation, the Initial Purchaser), its affiliates,

<PAGE>   31
                                                                              27

their respective officers, directors, employees, representatives and agents, and
each person, if any, who controls such Holder within the meaning of the
Securities Act or the Exchange Act (collectively referred to for purposes of
this Section 5.05 as a Holder) from and against any loss, claim, damage or
liability, joint or several, or any action in respect thereof (including,
without limitation, any loss, claim, damage, liability or action relating to
purchases and sales of Warrants or Warrant Shares), to which that Holder may
become subject, whether commenced or threatened, under the Securities Act, the
Exchange Act, any other Federal or state statutory law or regulation, at common
law or otherwise, insofar as such loss, claim, damage, liability or action
arises out of, or is based upon, (i) any untrue statement or alleged untrue
statement of a material fact contained in any such Registration Statement or any
prospectus forming part thereof or in any amendment or supplement thereto or
(ii) the omission or alleged omission to state therein a material fact required
to be stated therein or necessary in order to make the statements therein, in
the light of the circumstances under which they were made, not misleading, and
shall reimburse each Holder promptly upon demand for any legal or other expenses
reasonably incurred by that Holder in connection with investigating or defending
or preparing to defend against or appearing as a third party witness in
connection with any such loss, claim, damage, liability or action as such
expenses are incurred; provided, however, that the Company shall not be liable
in any such case to the extent that any such loss, claim, damage, liability or
action arises out of, or is based upon, an untrue statement or alleged untrue
statement in or omission or alleged omission from any of such documents in
reliance upon and in conformity with any Holders' Information; and provided,
further, that with respect to any such untrue statement in or omission from any
related preliminary prospectus, the indemnity agreement contained in this
Section 5.05(a) shall not inure to the benefit of any Holder from whom the
person asserting any such loss, claim, damage, liability or action received
Warrants or Warrant Shares to the extent that such loss, claim, damage,
liability or action of or with respect to such Holder results from the fact that
both (A) a copy of the final prospectus was not sent or given to such person at
or prior to the written confirmation of the sale of such Warrants (in the case
of the sale of Warrants), to such person and (B) the untrue statement in or
omission from the related preliminary prospectus was corrected in the final
prospectus unless, in either case, such failure to deliver the final prospectus
was a result of noncompliance by the Company with Section 5.01. This indemnity
agreement will be in addition to any liability which the Company may otherwise


<PAGE>   32

                                                                              28

have to a Holder. The Company shall also indemnify underwriters, selling
brokers, dealer-managers and similar securities industry professionals
participating in the distribution (in each case as described in the Registration
Statement), their officers and directors and each person who controls such
persons within the meaning of the Securities Act or the Exchange Act to the same
extent as provided above with respect to the indemnification of the Holders of
the Securities if requested by such Holders.

                  (b) In connection with any Registration Statement each Holder,
severally and not jointly, shall indemnify and hold harmless the Company, its
affiliates, their respective officers, directors, employees, representatives and
agents, and each person, if any, who controls the Company within the meaning of
the Securities Act or the Exchange Act (collectively referred to for purposes of
this Section 5.05 as the Company), from and against any loss, claim, damage or
liability, joint or several, or any action in respect thereof, to which the
Company may become subject, whether commenced or threatened, under the
Securities Act, the Exchange Act, any other Federal or state statutory law or
regulation, at common law or otherwise, insofar as such loss, claim, damage,
liability or action arises out of, or is based upon, (i) any untrue statement or
alleged untrue statement of a material fact contained in any such Registration
Statement or any prospectus forming part thereof or in any amendment or
supplement thereto or (ii) the omission or alleged omission to state therein a
material fact required to be stated therein or necessary in order to made the
statements therein, in the light of the circumstances under which they were
made, not misleading, but in each case only to the extent that the untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with any Holders' Information furnished to
the Company by such Holder, and shall reimburse the Company for any legal or
other expenses reasonably incurred by the Company in connection with
investigating or defending or preparing to defend against or appearing as a
third party witness in connection with any such loss, claim, damage, liability
or action as such expenses are incurred; provided, however, that no such Holder
shall be liable for any indemnity claims hereunder in excess of the amount of
net proceeds received by such Holder from the sale of Warrants, in the case of
the Warrant Shelf Registration Statement, or the Current Market Value of Warrant
Shares at the time they were received in the case of the Common Stock Shelf
Registration Statement.

                  (c) Promptly after receipt by an indemnified party under this
Section 5.05 of notice of any claim or the 


<PAGE>   33

                                                                              29

commencement of any action, the indemnified party shall, if a claim in respect
thereof is to be made against the indemnifying party pursuant to Section 5.05(a)
or 5.05(b), notify the indemnifying party in writing of the claim or the
commencement of that action; provided, however, that the failure to notify the
indemnifying party shall not relieve it from any liability which it may have
under this Section 5.05 except to the extent that it has been materially
prejudiced (through the forfeiture of substantive rights or defenses) by such
failure; and provided, further, that the failure to notify the indemnifying
party shall not relieve it from any liability which it may have to an
indemnified party otherwise than under this Section 5.05. If any such claim or
action shall be brought against an indemnified party, and it shall notify the
indemnifying party thereof, the indemnifying party shall be entitled to
participate therein and, to the extent that it wishes, jointly with any other
similarly notified indemnifying party, to assume the defense thereof with
counsel reasonably satisfactory to the indemnified party. After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 5.05 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than the reasonable costs of investigation; provided, however,
that an indemnified party shall have the right to employ its own counsel in any
such action, but the fees, expenses and other charges of such counsel for the
indemnified party will be at the expense of such indemnified party unless (1)
the employment of counsel by the indemnified party has been authorized in
writing by the indemnifying party, (2) the indemnified party has reasonably
concluded (based upon advice of counsel to the indemnified party) that there may
be legal defenses available to it or other indemnified parties that are
different from or in addition to those available to the indemnifying party, (3)
a conflict or potential conflict exists (based upon advice of counsel to
the indemnified party) between the indemnified party and the indemnifying party
(in which case the indemnifying party will not have the right to direct the
defense of such action on behalf of the indemnified party) or (4) the
indemnifying party has not in fact employed counsel reasonably satisfactory to
the indemnified party to assume the defense of such action within a reasonable
time after receiving notice of the commencement of the action, in each of which
cases the reasonable fees, disbursements and other charges of counsel will be at
the expense of the indemnifying party or parties. It is understood that the
indemnifying party or parties shall not, in connection with any proceeding or

<PAGE>   34

                                                                              30

related proceedings in the same jurisdiction, be liable for the reasonable fees,
disbursements and other charges of more than one separate firm of attorneys (in
addition to any local counsel) at any one time for all such indemnified party or
parties. Each indemnified party, as a condition of the indemnity agreements
contained in Sections 5.05(a) and 5.05(b), shall use all reasonable efforts to
cooperate with the indemnifying party in the defense of any such action or
claim. No indemnifying party shall be liable for any settlement of any such
action effected without its written consent (which consent shall not be
unreasonably withheld), but if settled with its written consent or if there be a
final judgment for the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss or liability by reason of such settlement or judgment. No indemnifying
party shall, without the prior written consent of the indemnified party (which
consent shall not be unreasonably withheld), effect any settlement of any
pending or threatened proceeding in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such proceeding.

                  (d) If the indemnification provided for above is unavailable
or insufficient to hold harmless an indemnified party under Section 5.05(a) or
5.05(b), then each indemnifying party shall, in lieu of indemnifying such
indemnified party, contribute to the amount paid or payable by such indemnified
party as a result of such loss, claim, damage or liability, or action in respect
thereof, (i) in such proportion as shall be appropriate to reflect the relative
benefits received by the Company, on the one hand, and a Holder, on the other,
or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company, on the one hand, and such Holder, on the other, with respect to the
statements or omissions that resulted in such loss, claim, damage or liability,
or action in respect thereof, as well as any other relevant equitable
considerations. The relative fault 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 the
Company or information supplied by the Company, on the one hand, or to any
Holders' Information supplied by such Holder, on the other, the intent of the
parties and their relative knowledge, access 

<PAGE>   35

                                                                              31

to information and opportunity to correct or prevent such untrue statement or
omission. The parties hereto agree that it would not be just and equitable if
contributions pursuant to this Section 5.05(d) were to be determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to herein. The amount paid or payable by
an indemnified party as a result of the loss, claim, damage or liability, or
action in respect thereof, referred to above in this Section 5.05(d) shall be
deemed to include, for purposes of this Section 5.05(d), any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending or preparing to defend any such action or claim.
Notwithstanding the provisions of this Section 5.05(d), an indemnifying party
that is a Holder shall not be required to contribute any amount in excess of the
amount by which the total price at which the Warrants sold, in the case of the
Warrant Shelf Registration Statement, and the Current Market Value of the
Warrant Shares at the time they were received, in the case of the Common Stock
Registration Statement, by such indemnifying party to any purchaser exceeds the
amount of any damages which such indemnifying party has otherwise paid or become
liable to pay by reason of any 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 be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

                  (e) The agreements contained in this Section 5.05 shall
survive the sale of the Securities pursuant to the Registration Statements and
shall remain in full force and effect, regardless of any termination or
cancelation of this Warrant Agreement or any investigation made by or on behalf
of any indemnified party.

                  SECTION 5.06. Additional Acts. If the sale of Warrants or the
issuance or sale of any Common Stock or other securities issuable upon the
exercise of the Warrants requires registration or approval of any governmental
authority (other than the registration requirements under the Securities Act),
or the taking of any other action under the laws of the United States or any
political subdivision thereof before such securities may be validly offered or
sold in compliance with such laws, then the Company covenants that it will, in
good faith and as expeditiously as reasonably possible, use its reasonable best
efforts to secure and maintain such registration or approval or to take such
other action, as the case may be. The Company shall promptly notify the Warrant

                  SECTION 6.01. Appointment of Warrant Agent. The Company hereby
appoints the Warrant Agent to act as agent for the Company in accordance with
the provisions of this Warrant Agreement and the Warrant Agent hereby accepts

                  SECTION 6.02. Rights and Duties of Warrant Agent. (a) Agent
for the Company. In acting under this Warrant Agreement and in connection with

Warrants.

                  (b) Counsel. The Warrant Agent may consult with counsel
satisfactory to it (and may require an Opinion of

                                                                              33

Counsel before it acts or refrains from acting), and the advice of such counsel
shall be full and complete authorization and protection in respect of any action
taken, suffered or omitted by it hereunder in good faith and in accordance with
the advice of such counsel.

                  (c) Documents. The Warrant Agent shall be protected and shall
incur no liability for or in respect of any action taken or thing suffered by it
in reliance upon any Warrant Certificate, notice, direction, consent,
certificate, affidavit, statement or other paper or document reasonably believed
by it to be genuine and to have been presented or signed by the proper parties.

                  (d) No Implied Obligations. The Warrant Agent shall be
obligated to perform only such duties as are specifically set forth herein and
in the Warrant Certificates, and no implied duties or obligations of the Warrant
Agent shall be read into this Warrant Agreement or the Warrant Certificates
against the Warrant Agent. The Warrant Agent shall not be under any obligation
to take any action hereunder which may tend to involve it in any expense or
liability for which it does not receive indemnity if such indemnity is
reasonably requested. The Warrant Agent shall not be accountable or under any
duty or responsibility for the use by the Company of any of the Warrant
Certificates countersigned by the Warrant Agent and delivered by it to the
Holders or on behalf of the Holders pursuant to this Warrant Agreement or for
the application by the Company of the proceeds of the Warrants. The Warrant
Agent shall have no duty or responsibility in case of any default by the Company
in the performance of its covenants or agreements contained herein or in the
Warrant Certificates or in the case of the receipt of any written demand from a
Holder with respect to such default, including any duty or responsibility to
initiate or attempt to initiate any proceedings at law or otherwise.

                  (e) Not Responsible for Adjustments or Validity of Stock. The
Warrant Agent shall not at any time be under any duty or responsibility to any
Holder to determine whether any facts exist that may require an adjustment of
the number of shares of Common Stock issuable upon exercise of each Warrant or
the Exercise Price, or with respect to the nature or extent of any adjustment
when made, or with respect to the method employed, or herein or in any supple
mental agreement provided to be employed, in making the same. The Warrant Agent
shall not be accountable with respect to the validity or value of any shares of
Common Stock or of any securities or property which may at any time be issued or
delivered upon the exercise of any Warrant or 

<PAGE>   38

                                                                              34

upon any adjustment pursuant to Article IV, and it makes no representation with
respect thereto. The Warrant Agent shall not be responsible for any failure of
the Company to make any cash payment or to issue, transfer or deliver any shares
of Common Stock or stock certificates upon the surrender of any Warrant
Certificate for the purpose of exercise or upon any adjustment pursuant to
Article IV, or to comply with any of the covenants of the Company contained in
Article IV.

                  SECTION 6.03. Individual Rights of Warrant Agent. The Warrant
Agent and any stockholder, director, officer or employee of the Warrant Agent
may buy, sell or deal in any of the Warrants or other securities of the Company
or its affiliates and may otherwise deal with the Company or its affiliates with
the same rights it would have if it were not Warrant Agent. Nothing herein shall
preclude the Warrant Agent from acting in any other capacity for the Company or
for any other legal entity.

                  SECTION 6.04. Warrant Agent's Disclaimer. The Warrant Agent
shall not be responsible for and makes no representation as to the validity or
adequacy of this Warrant Agreement or the Warrant Certificates and it shall not
be responsible for any statement in this Warrant Agreement or the Warrant
Certificates other than its countersignature thereon.

                  SECTION 6.05. Compensation and Indemnity. The Company agrees
to pay the Warrant Agent from time to time reasonable compensation for its
services as agreed and to reimburse the Warrant Agent upon request for all
reasonable out-of-pocket expenses incurred by it, including the reasonable
compensation and expenses of the Warrant Agent's agents and counsel as agreed.
The Company shall indemnify the Warrant Agent against any loss, liability or
expense (including reasonable agents' and attorneys' fees and expenses) incurred
by it without negligence or bad faith on its part arising out of or in
connection with the acceptance or performance of its duties under this Warrant
Agreement. The Warrant Agent shall notify the Company promptly of any claim for
which it may seek indemnity. The Company need not reimburse any expense or
indemnify against any loss or liability incurred by the Warrant Agent through
wilful misconduct, negligence or bad faith. The Company's payment obligations
pursuant to this Section 6.05 shall survive the termination of this Warrant
Agreement.

                  To secure the Company's payment obligations under this Warrant
Agreement, the Warrant Agent shall have a lien

                                                                              35

prior to the Holders on all money or property held or collected by the Warrant
Agent.

                  SECTION 6.06. Successor Warrant Agent. (a) The Company To
Provide and Maintain Warrant Agent. The Company agrees for the benefit of the
Holders that there shall at all times be a Warrant Agent hereunder until all the
Warrants have been exercised or are no longer exercisable.

                  (b) Resignation and Removal. The Warrant Agent may at any time
resign by giving written notice to the Company of such intention on its part,
specifying the date on which its desired resignation shall become effective;
provided, however, that such date shall not be less than 60 days after the date
on which such notice is given unless the Company otherwise agrees. The Warrant
Agent hereunder may be removed at any time by the filing with it of an
instrument in writing signed by or on behalf of the Company and specifying such
removal and the date when it shall become effective, which date shall not be
less than 60 days after such notice is given unless the Warrant Agent otherwise
agrees. Any removal under this Section 6.06 shall take effect upon the
appointment by the Company as hereinafter provided of a successor Warrant Agent
(which shall be a bank or trust company authorized under the laws of the
jurisdiction of its organization to exercise corporate trust powers) and the
acceptance of such appointment by such successor Warrant Agent. At any time that
the Warrant Agent is also acting as Trustee under the Indenture and holders of
the Notes remove the Trustee pursuant to Section 7.08 of the Indenture, the
Company shall remove the Warrant Agent pursuant to this Section 6.06(b).

                  (c) The Company To Appoint Successor. In the event that at any
time the Warrant Agent shall resign, or shall be removed, or shall become
incapable of acting, or shall be adjudged a bankrupt or insolvent, or shall
commence a voluntary case under the Federal bankruptcy laws, as now or hereafter
constituted, or under any other applicable Federal or state bankruptcy,
insolvency or similar law or shall consent to the appointment of or taking
possession by a receiver, custodian, liquidator, assignee, trustee, sequestrator
(or other similar official) of the Warrant Agent or its property or affairs, or
shall make an assignment for the benefit of creditors, or shall admit in writing
its inability to pay its debts generally as they become due, or shall take
corporate action in furtherance of any such action, or a decree or order for
relief by a court having jurisdiction in the premises shall have been entered in
respect of the Warrant Agent in an involuntary case under the Federal bankruptcy
laws, as now or hereafter 

<PAGE>   40

                                                                              36

constituted, or any other applicable Federal or state bankruptcy, insolvency or
similar law, or a decree or order by a court having jurisdiction in the premises
shall have been entered for the appointment of a receiver, custodian,
liquidator, assignee, trustee, sequestrator (or similar official) of the Warrant
Agent or of its property or affairs, or any public officer shall take charge or
control of the Warrant Agent or of its property or affairs for the purpose of
rehabilitation, conservation, winding up or liquidation, a successor Warrant
Agent, qualified as aforesaid, shall be appointed by the Company by an
instrument in writing, filed with the successor Warrant Agent. Upon the
appointment as aforesaid of a successor Warrant Agent and acceptance by the
successor Warrant Agent of such appointment, the Warrant Agent shall cease to be
Warrant Agent hereunder; provided, however, that in the event of the resignation
of the Warrant Agent under this subsection (c), such resignation shall be
effective on the earlier of (i) the date specified in the Warrant Agent's notice
of resignation and (ii) the appointment and acceptance of a successor Warrant
Agent hereunder.

                  (d) Successor To Expressly Assume Duties. Any successor
Warrant Agent appointed hereunder shall execute, acknowledge and deliver to its
predecessor and to the Company an instrument accepting such appointment
hereunder, and thereupon such successor Warrant Agent, without any further act,
deed or conveyance, shall become vested with all the rights and obligations of
such predecessor with like effect as if originally named as Warrant Agent
hereunder, and such predecessor, upon payment of its charges and disbursements
then unpaid, shall thereupon become obligated to transfer, deliver and pay over,
and such successor Warrant Agent shall be entitled to receive, all monies,
securities and other property on deposit with or held by such predecessor, as
Warrant Agent hereunder.

                  (e) Successor by Merger. If the Warrant Agent consolidates
with, merges or converts into, or transfers all or substantially all its
corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Warrant Agent.

of Section 13 or 15(d) of the Exchange Act the Company shall file with the SEC
and provide the Warrant Agent and Holders within 15 days after it files them
with the SEC, copies of its annual report and the information, documents and
other reports that are specified in Sections 13 and 15(d) of the Exchange Act.
In addition, following a public offering of the common stock of the Company, the
Company shall furnish to the Warrant Agent and the Holders, promptly upon their
becoming available, copies of the annual report to stockholders and any other
information provided by the Company to its public stockholders generally.

                  SECTION 7.02. Persons Benefitting. Nothing in this Warrant
Agreement is intended or shall be construed to confer upon any Person other than

or by reason of this Warrant Agreement or any part hereof.

                  SECTION 7.03. Rights of Holders. Holders of unexercised

receive notice of or vote at any meeting of the stockholders, (iii) consent to
any action of the stockholders, (iv) receive notice of any other proceedings of
the Company, (v) exercise any preemptive right or (vi) exercise any other rights
whatsoever as stockholders of the Company.

                  SECTION 7.04. Amendment. This Warrant Agreement may be amended
by the parties hereto without the consent of any Holder for the purpose of
curing any ambiguity, or of curing, correcting or supplementing any defective
provision contained herein or adding or changing any other provisions with
respect to matters or questions arising under this Warrant Agreement as the
Company and the Warrant Agent may deem necessary or desirable (including without
limitation any addition or modification to provide for compliance with the
transfer restrictions set forth herein); provided, however, that such action
shall not adversely affect the rights of any of the Holders. Any amendment or
supplement to this Warrant Agreement that has an adverse effect on the interests

the then outstanding Warrants. The consent of each Holder affected shall be
required for any amendment pursuant to which the Exercise Price would be
increased, the number of Warrant Shares issuable upon exercise of Warrants would
be decreased (other than pursuant to adjustments provided herein) or the
antidilution provisions in Article IV are altered in a manner which adversely
affects the Holders. In determining whether the Holders of the required number

owned by the Company or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company shall
be disregarded and deemed not to be outstanding, except that, for the purpose of
determining whether the Warrant Agent shall be protected in relying on any such
direction, waiver or consent, only Warrants which the Warrant Agent knows are so
owned shall be so disregarded. Also, subject to the foregoing, only Warrants
outstanding at the time shall be considered in any such determination.

Committee.

3.2      Administration.

(a)      Subject to the provisions of this Plan and directions from the Board, 
the Committee is authorized to:

(i)      determine the Persons to whom Awards are to be granted;

(ii)     determine the types and combinations of Awards to be granted; the 
number of Shares to be covered by an Award; the exercise price of an Award; the
time or times when an Award shall be granted and may be exercised; the terms,
performance criteria or other conditions, vesting periods or any restrictions
for an Award; any restrictions on Shares acquired pursuant to the exercise of an

                                       -5-
<PAGE>   6

(iii)    conclusively interpret the provisions of this Plan;

(iv)     prescribe, amend and rescind rules and regulations relating to this 
Plan;

(v)      rely upon employees of the Company for such clerical and recordkeeping
duties as may be necessary in connection with the administration of this Plan;

(vi)     accelerate or defer (with the consent of the Participant) the vesting
of any rights pursuant to an Award; and

(vii)    make all other determinations and take all other actions necessary or
advisable for the administration of this Plan.

         The President of the Company shall also be authorized, subject to the
         provisions of this Plan and directions from the Board and the
         Committee, to determine the types and combinations of Awards to be
         granted; the number of Shares to be covered by an Award; the exercise
         price of an Award; the time or times when an Award shall be granted and
         may be exercised; the terms, performance criteria or other conditions,
         vesting periods or any restrictions for an Award; any restrictions on
         Shares acquired pursuant to the exercise of an Award; and any other
         terms and conditions of an Award; provided, however, that the President
         of the Company may not (1) grant any Award that would be subject to
         Section 16 of the Exchange Act (without regard to Rule 16b-3 of the
         Securities and Exchange Commission), (2) grant Awards to any one person
         with respect to more than 100,000 Shares in the aggregate (which number
         shall be adjusted pro rata in the event of any adjustment to the
         limitation set forth in Section 4.1 hereof), or (3) modify any Award
         made by the Committee or Board.

(b)      A majority of the Committee members shall constitute a quorum for 
action by the Committee. All determinations of the Committee in connection with
the Plan shall be made by not less than a majority of its members. All questions
of interpretation and application of this Plan or pertaining to any question of
fact or Award granted hereunder will be decided by the Committee, whose decision
will be final, conclusive and binding upon the Company and each other affected
party.

         SECTION 4.   SHARES SUBJECT TO PLAN

4.1      Limitations. The maximum number of Shares that may be issued with 
respect to Awards granted pursuant to this Plan shall not exceed 20,000,000
unless increased or decreased by reason of changes in the capitalization of the
Company as hereinafter provided or by amendment of this Plan. The Shares issued
pursuant to this Plan may be authorized but unissued Shares, or may be issued
Shares which have been reacquired by the Company.

4.2      Changes. To the extent that any Award granted pursuant to this Plan 
shall be forfeited, shall expire or shall be cancelled, in whole or in part,
then the number of Shares covered by the Award so forfeited, expired or
cancelled may again be awarded pursuant to the provisions of this Plan. In





                                       -6-
<PAGE>   7

the event that Shares are delivered to the Company in full or partial payment of
the exercise price for the exercise of a Stock Option, the number of Shares
available for future Awards granted pursuant to this Plan shall be reduced only
by the net number of Shares issued upon the exercise of the Stock Option. Awards
that may be satisfied either by the issuance of Shares or by cash or other
consideration shall, until the form of consideration to be paid is finally
determined, be counted against the maximum number of Shares that may be issued
pursuant to this Plan. If the Award is ultimately satisfied by the payment of
consideration other than Shares, such Shares may again be made the subject of an
Award granted pursuant to this Plan. Awards will not reduce the number of Shares
that may be issued pursuant to this Plan if the settlement of the Award will not
require the issuance of Shares, as, for example, a Stock Appreciation Right that
can be satisfied only by the payment of cash.

         SECTION 5.   ELIGIBILITY

         Eligibility for participation in this Plan shall be confined to those
individuals who are employed by the Company or a Subsidiary and such Consultants
and non-employee Directors as may be designated by the Committee. In making any
determination as to Persons to whom Awards shall be granted, the type of Award
and/or the number of Shares to be covered by the Award, the Committee shall
consider the position and responsibilities of the Person, the importance of the
Person to the Company, the duties of the Person, the past, present and potential
contributions of the Person to the growth and success of the Company and such
other factors as the Committee may deem relevant in connection with
accomplishing the purposes of this Plan.

         SECTION 6.   STOCK OPTIONS

6.1      Grants. The Committee may grant Stock Options alone or in addition to 
other Awards granted pursuant to this Plan to any eligible Person. Each Person
so selected shall be offered a Stock Option to purchase the number of Shares
determined by the Committee. The Committee shall specify whether such Stock
Option is an Incentive Stock Option or Non-Qualified Stock Option and any other
terms or conditions relating to such Award; provided, however only employees of
the Company or a Subsidiary may be granted Incentive Stock Options. To the
extent that any Stock Option designated as an Incentive Stock Option does not
qualify as an Incentive Stock Option (whether because of its provisions, the
failure of the shareholders of the Company to authorize the issuance of
Incentive Stock Options, the time or manner of its exercise or otherwise), such
Stock Option or the portion thereof which does not qualify shall be deemed to
constitute a Non-Qualified Stock Option. Each Person to be granted a Stock
Option shall enter into a written agreement with the Company, in such form as
the Committee may prescribe, setting forth the terms and conditions (including,
without limitation, the exercise price and vesting schedule) of the Stock
Option. At any time and from time to time, the Optionee and the Committee may
agree to modify an option agreement in such respects as they may deem
appropriate, including, without limitation, the conversion of an Incentive Stock
Option into a Non-Qualified Stock Option. The Committee may require that an
Optionee meet certain conditions before the Stock Option or a portion thereof
may vest or be exercised, as, for example, that the Optionee remain in the
employ of the Company or a Subsidiary for a stated period or periods of time.

6.2      Incentive Stock Options Limitations.

(a)      In no event shall any individual be granted Incentive Stock Options to
the extent that the Shares covered by any Incentive Stock Options (and any
incentive stock options granted pursuant to any other plans of the Company or
its Subsidiaries) that may be exercised for the first time by such individual in
any calendar year have an aggregate Fair Market Value in excess of $100,000. For
this purpose, the Fair Market Value of the Shares shall be determined as of the
date(s) on which the Incentive Stock Options are granted. It is intended that
the limitation on Incentive Stock Options provided in this Subsection 6.2(a) be
the maximum limitation on Stock Options which may be considered Incentive Stock
Options pursuant to the Code.

(b)      The option exercise price of an Incentive Stock Option shall not be 
less than one hundred percent (100%) of the Fair Market Value of the Shares
subject to such Incentive Stock Option on the date of the grant of such
Incentive Stock Option.

(c)      Notwithstanding anything herein to the contrary, in no event shall any
employee owning more than ten percent (10%) of the total combined voting power
of the Company or any Subsidiary be granted an Incentive Stock Option unless the
option exercise price of such Incentive Stock Option shall be at least one
hundred ten percent (110%) of the Fair Market Value of the Shares subject to
such Incentive Stock Option on the date of the grant of such Incentive Stock
Option.

(d)      In no event shall any individual be granted an Incentive Stock Option 
after the expiration of ten (10) years from the date this Plan is adopted or is
approved by the shareholders of the Company (if shareholder approval is required
by Section 422 of the Code).

(e)      To the extent shareholder approval of this Plan is required by Section
422 of the Code, no individual shall be granted an Incentive Stock Option unless
this Plan is approved by the shareholders of the Company within twelve (12)
months before or after the date this Plan is initially adopted. In the event
this Plan is amended to increase the number of Shares subject to issuance upon
the exercise of Incentive Stock Options or to change the class of employees
eligible to receive Incentive Stock Options, no individual shall be granted an
Incentive Stock Option unless such amendment is approved by the shareholders of
the Company within twelve (12) months before or after such amendment.

(f)      No Incentive Stock Option shall be granted to any employee owning more
than ten percent (10%) of the total combined voting power of the Company or any
Subsidiary unless the term of such Incentive Stock Option is equal to or less
than five (5) years measured from the date on which such Incentive Stock Option
is granted.

6.3      Option Term. The term of a Stock Option shall be for such period of 
time from the date of its grant as may be determined by the Committee; provided,
however, that no Incentive Stock Option shall be exercisable later than ten (10)
years from the date of its grant.



                                       -8-
<PAGE>   9

6.4      Time of Exercise. No Stock Option may be exercised unless it is 
exercised prior to the expiration of its stated term and, in connection with
options granted to employees of the Company or its Subsidiaries, at the time of
such exercise, the Optionee is, and has been continuously since the date of
grant of such Stock Option, employed by the Company or a Subsidiary, except
that:

(a)      A Stock Option may, to the extent vested as of the date the Optionee 
ceases to be an employee of the Company or a Subsidiary, be exercised during the
three-month period immediately following the date the Optionee ceases (for any
reason other than death, Disability or Retirement) to be an employee of the
Company or a Subsidiary (or within such other period as may be specified in the
applicable option agreement), provided that, if the Stock Option has been
designated as an Incentive Stock Option and the option agreement provides for a
longer exercise period, the exercise of such Stock Option after such three-month
period shall be treated as the exercise of a Non-Qualified Stock Option;

(b)      If the Optionee dies while entitled to exercise a Stock Option, such 
Stock Option may, to the extent vested as of the date of the Optionee's death,
be exercised by the Optionee's Designated Beneficiary during the three year
period immediately following the date of the Optionee's death (or within such
other period as may be specified in the applicable option agreement); provided
that, if the Stock Option has been designated as an Incentive Stock Option and
the option agreement provides for a longer exercise period, the exercise of such
Stock Option after such one-year period shall be treated as the exercise of a
Non-Qualified Stock Option;

(c)      If the Optionee ceases to be an employee of the Company or a Subsidiary
by reason of the Optionee's Disability or Retirement, a Stock Option, to the
extent vested as of the date the Optionee ceases to be an employee of the
Company or a Subsidiary, may be exercised during the three year period
immediately following the date of such cessation of employment (or within such
other period as may be specified in the applicable option agreement); provided
that, if the Stock Option has been designated as an Incentive Stock Option and
the option agreement provides for a longer exercise period, the exercise of such
Stock Option after such one-year period shall be treated as the exercise of a
Non-Qualified Stock Option; and

         Nothing contained in this Subsection 6.4 will be deemed to extend the
         term of a Stock Option or to revive any Stock Option which has
         previously lapsed or been cancelled, terminated or surrendered. Stock
         Options granted under this Plan to Consultants or non-employee
         Directors will contain such terms and conditions with respect to the
         death or disability of a Consultant or non-employee Director or
         termination of a Consultant's or non-employee Director's relationship
         with the Company as the Committee deems necessary or appropriate. Such
         terms and conditions will be set forth in the option agreements
         evidencing the grant of such Stock Options.

<PAGE>   10

6.5      Vesting of Stock Options.

(a)      Each Stock Option granted pursuant to this Plan may only be exercised 
to the extent that the Optionee is vested in such Stock Option. Each Stock
Option shall vest separately in accordance with the option vesting schedule
determined by the Committee, which will be incorporated in the option agreement
entered into between the Company and such Optionee. The option vesting schedule
may be accelerated if, in the sole discretion of the Committee, the acceleration
of the option vesting schedule would be in the best interests the Company.

(b)      In the event of the dissolution or liquidation of the Company, each 
Stock Option granted pursuant to this Plan shall terminate as of a date to be
fixed by the Committee; provided, however, that not less than thirty (30) days'
written notice of the date so fixed shall be given to each Optionee. During such
period all Stock Options which have not previously been terminated, exercised or
surrendered will (subject to the provisions of Subsections 6.3 and 6.4) fully
vest and become exercisable, notwithstanding the vesting schedule set forth in
the option agreement evidencing the grant of such Stock Option. Upon the date
fixed by the Committee, any unexercised Stock Options shall terminate and be of
no further effect.

(c)      Upon the occurrence of a Change in Control, all Stock Options and any
associated Stock Appreciation Rights shall become fully vested and immediately
exercisable, and shall remain exercisable for their full terms except as
provided in Subsections 6.5(b) and 12(a)(ii).

6.6      Manner of Exercise of Stock Options.

(a)      Except as otherwise provided in this Plan, Stock Options may be 
exercised as to Shares only in amounts and at intervals of time specified in the
written option agreement between the Company and the Optionee. Each exercise of
a Stock Option, or any part thereof, shall be evidenced by a written notice
delivered by the Optionee to the Company. The purchase price of the Shares as to
which a Stock Option shall be exercised shall be paid in full at the time of
exercise, and may be paid to the Company either:

(i)      in cash (including check, bank draft or money order); or

(ii)     by other consideration deemed acceptable by the Committee in its sole
discretion.

(b)      If, as permitted in the option agreement or by the Committee, an 
Optionee delivers Shares already owned by the Optionee in full or partial
payment of the exercise price for any Stock Option or the Optionee elects to
have the Company retain that number of Shares out of the Shares being acquired
through the exercise of the Stock Option having a Fair Market Value equal to the
exercise price of the Stock Option being exercised, the Committee may, in its
sole discretion, authorize the grant of a new Stock Option (a "Reload Option")
for that number of Shares equal to the number of already owned Shares
surrendered or newly acquired Shares being retained by the Company in payment of
the option exercise price of the underlying Stock Option being exercised. The
grant of a Reload Option will become effective upon the exercise of the
underlying Stock Option. The option




                                      -10-
<PAGE>   11

exercise price of the Reload Option shall be the Fair Market Value of a Share on
the effective date of the grant of the Reload Option. Each Reload Option shall
be exercisable no later than the time when the underlying stock option being
exercised could be last exercised. The Committee may also specify additional
terms, conditions and restrictions for the Reload Option and the Shares to be
acquired upon the exercise thereof.

(c)      The amount, as determined by the Committee, of any federal, state or 
local tax required to be withheld by the Company due to the exercise of a Stock
Option shall, subject to the authorization of the Committee, be satisfied, at
the election of the Optionee, either (i) by payment by the Optionee to the
Company of the amount of such withholding obligation in cash or other
consideration acceptable to the Committee in its sole discretion or (ii) through
either the retention by the Company of a number of Shares out of the Shares
being acquired through the exercise of the Stock Option or the delivery of
already owned Shares having a Fair Market Value equal to the amount of the
withholding obligation. If an Optionee elects to use the method described in
clause (ii) of the preceding sentence in full or partial satisfaction of any tax
liability resulting from the exercise of a Stock Option, the Committee may
authorize the grant of a Reload Option for that number of Shares as shall equal
the number of Shares used to satisfy the tax liabilities of the Optionee arising
out of the exercise of such Stock Option. Such Reload Option will be granted at
the price and on the terms set forth in Subsection 6.6 (b). The cash payment or
an amount equal to the Fair Market Value of the Shares so withheld, as the case
may be, shall be remitted by the Company to the appropriate taxing authorities.

(d)      An Optionee shall not have any of the rights of a shareholder of the 
Company with respect to the Shares subject to a Stock Option except to the
extent that such Stock Option is exercised and one or more certificates
representing such Shares shall have been delivered to the Optionee.

         SECTION 7.   STOCK APPRECIATION RIGHTS

7.1      Grants. The Committee may grant to any eligible Consultant, 
non-employee Director or employee of the Company or a Subsidiary either
Non-Tandem Stock Appreciation Rights or Tandem Stock Appreciation Rights. Stock
Appreciation Rights shall be subject to such terms and conditions as the
Committee shall impose. The grant of the Stock Appreciation Right may provide
that the holder will be paid for the value of the Stock Appreciation Right
either in cash or in Shares, or a combination thereof, at the sole discretion of
the Committee. In the event of the exercise of a Stock Appreciation Right
payable in Shares, the holder of the Stock Appreciation Right shall receive that
number of whole Shares having an aggregate Fair Market Value on the date of
exercise equal to the value obtained by multiplying (i) either (a) in the case
of a Tandem Stock Appreciation Right, the difference between the Fair Market
Value of a Share on the date of exercise over the per share exercise price of
the related Stock Option, or (b) in the case of a Non-Tandem Stock Appreciation
Right, the difference between the Fair Market Value of a Share on the date of
exercise over the Fair Market Value on the date of the grant by (ii) the number
of Shares as to which the Stock Appreciation Right is exercised. However,
notwithstanding the foregoing, the Committee, in its sole discretion, may place
a ceiling on the amount payable upon exercise of a Stock Appreciation Right, but
any such limitation shall be specified at the time that the Stock Appreciation
Right is granted.




                                      -11-
<PAGE>   12

7.2      Exercisability. A Tandem Stock Appreciation Right granted in connection
with an Incentive Stock Option (i) may be exercised at, and only at, the times
and to the extent the related Incentive Stock Option is exercisable, (ii) will
expire upon the termination of the related Incentive Stock Option, (iii) may not
exceed 100% of the difference between the exercise price of the related
Incentive Stock Option and the Fair Market Value of the Shares subject to the
related Incentive Stock Option at the time the Tandem Stock Appreciation Right
is exercised and (iv) may be exercised at, and only at, such times as the Fair
Market Value of the Shares subject to the related Incentive Stock Option exceeds
the exercise price of the related Incentive Stock Option. A Tandem Stock
Appreciation Right may be transferred at, and only at, the times and to the
extent the related Stock Option is transferable. If a Tandem Stock Appreciation
Right is granted, there shall be surrendered and cancelled from the related
Stock Option at the time of exercise of the Tandem Stock Appreciation Right, in
lieu of exercise pursuant to the related Stock Option, that number of Shares of
the Stock Option to which the exercised Tandem Stock Appreciation Right relates.

7.3      Certain Limitations on Non-Tandem Stock Appreciation Rights. A 
Non-Tandem Stock Appreciation Right will be exercisable as provided by the
Committee and will have such other terms and conditions as the Committee may
determine. A Non-Tandem Stock Appreciation Right is subject to acceleration of
vesting or immediate termination in certain circumstances in the same manner as
Stock Options pursuant to Subsections 6.4 and 6.5 of this Plan.

7.4      Limited Stock Appreciation Rights. The Committee may grant limited 
Stock Appreciation Rights, either as Tandem Stock Appreciation Rights or
Non-Tandem Stock Appreciation Rights, which may become exercisable only upon the
occurrence of a Change in Control or such other event as the Committee may
designate at the time of grant or thereafter.

         SECTION 8.   RESTRICTED STOCK

8.1      Grants. The Committee may grant Awards of Restricted Stock to any 
eligible Consultant, non-employee Director or employee of the Company or a
Subsidiary for such minimum consideration, if any, as may be required by
applicable law or such greater consideration as may be determined by the
Committee, in its sole discretion. The terms and conditions of the Restricted
Stock shall be specified by the grant agreement. The Committee, in its sole
discretion, may specify any particular rights which the Participant to whom a
grant of Restricted Stock is made shall have in the Restricted Stock during the
restriction period and the restrictions applicable to the particular Award, the
vesting schedule (which may be based on service, performance or other factors)
and rights to acceleration of vesting (including, without limitation, whether
non-vested Shares are forfeited or vested upon termination of employment).
Further, the Committee may grant performance-based Awards consisting of
Restricted Stock by conditioning the grant, or vesting or such other factors,
such as the release, expiration or lapse of restrictions upon any such Award
(including the acceleration of any such conditions or terms) of such Restricted
Stock upon the attainment of specified performance goals or such other factors
as the Committee may determine. The Committee shall also determine when the
restrictions shall lapse or expire and the conditions, if any, pursuant to which
the Restricted Stock will be forfeited or sold back to the Company. Each



                                      -12-
<PAGE>   13

Award of Restricted Stock may have different restrictions and conditions. Unless
otherwise set forth in the grant agreement, Restricted Stock may not be sold,
pledged, encumbered or otherwise disposed of by the recipient until the
restrictions specified in the Award expire. Awards of Restricted Stock are
subject to acceleration of vesting, termination of restrictions and termination
in the same manner as Stock Options pursuant to Subsections 6.4 and 6.5 of this
Plan.

8.2      Awards and Certificates. Any Restricted Stock issued hereunder may be
evidenced in such manner as the Committee, in its sole discretion, shall deem
appropriate including, without limitation, book-entry registration or issuance
of a stock certificate or certificates. In the event any stock certificate is
issued in respect of Shares of Restricted Stock, such certificate shall bear an
appropriate legend with respect to the restrictions applicable to such Award.
The Company may retain, at its option, the physical custody of any stock
certificate representing any awards of Restricted Stock during the restriction
period or require that the certificates evidencing Restricted Stock be placed in
escrow or trust, along with a stock power endorsed in blank, until all
restrictions are removed or expire.

         SECTION 9.   PERFORMANCE AWARDS

9.1      Grants. A Performance Award may consist of either or both, as the 
Committee may determine, of (i) the right to receive Shares or Restricted Stock,
or any combination thereof as the Committee may determine or (ii) the right to
receive a fixed dollar amount payable in Shares, Restricted Stock, cash or any
combination thereof, as the Committee may determine. The Committee may grant
Performance Awards to any eligible Consultant, non-employee Director or employee
of the Company or a Subsidiary, for such minimum consideration, if any, as may
be required by applicable law or such greater consideration as may be determined
by the Committee, in its sole discretion. The terms and conditions of
Performance Awards shall be specified at the time of the grant and may include
provisions establishing the performance period, the performance criteria to be
achieved during a performance period, the criteria used to determine vesting
(including the acceleration thereof), whether Performance Awards are forfeited
or vest upon termination of employment during a performance period and the
maximum or minimum settlement values. Each Performance Award shall have its own
terms and conditions, which shall be determined in the sole discretion of the
Committee. If the Committee determines, in its sole discretion, that the
established performance measures or objectives are no longer suitable because of
a change in the Company's business, operations, corporate structure or for other
reasons that the Committee deems satisfactory, the Committee may modify the
performance measures or objectives and/or the performance period. Performance
Awards are subject to acceleration of vesting, termination of restrictions and
termination in the same manner as Stock Options pursuant to Subsections 6.4 and
6.5 of this Plan.

9.2      Terms and Conditions. Performance Awards may be valued by reference to
the Fair Market Value of a Share or according to any other formula or method
deemed appropriate by the Committee, in its sole discretion, including, but not
limited to, achievement of specific financial, production, sales, cost or
earnings performance objectives that the Committee believes to be relevant or
the Company's performance or the performance of the Shares measured against the
performance of the market, the Company's industry segment or its direct
competitors. Performance Awards may also




                                      -13-
<PAGE>   14

be conditioned upon the applicable Participant remaining in the employ of the
Company or one of its Subsidiaries for a specified period. Performance Awards
may be paid in cash, Shares (including Restricted Stock) or other consideration,
or any combination thereof. Performance Awards may be payable in a single
payment or in installments and may be payable at a specified date or dates or
upon attaining the performance objective or objectives, all at the sole
discretion of the Committee. The extent to which any applicable performance
objective has been achieved shall be conclusively determined by the Committee in
its sole discretion.

         SECTION 10.  OTHER AWARDS

         The Committee may grant to any eligible Consultant, non-employee
Director or employee of the Company or a Subsidiary other forms of Awards based
upon, payable in or otherwise related to, in whole or in part, Shares, if the
Committee, in its sole discretion, determines that such other form of Award is
consistent with the purposes of this Plan. The terms and conditions of such
other form of Award shall be specified in a written agreement which sets forth
the terms and conditions of such Award, including, but not limited to, the
price, if any, and the vesting schedule, if any, of such Award. Such Awards may
be granted for such minimum consideration, if any, as may be required by
applicable law or for such other greater consideration as may be determined by
the Committee, in its sole discretion.

         SECTION 11.  COMPLIANCE WITH SECURITIES AND OTHER LAWS

         As a condition to the issuance or transfer of any Award or any security
issuable in connection with such Award, the Company may require an opinion of
counsel, satisfactory to the Company, to the effect that (i) such issuance
and/or transfer will not be in violation of the Securities Act or any other
applicable securities laws and (ii) such issuance and/or transfer will not be in
violation of the rules and regulations of any securities exchange or automated
quotation system on which the Shares are listed or admitted to trading. Further,
the Company may refrain from issuing, delivering or transferring any Award or
any security issuable in connection with such Award until the Committee has
determined that such issuance, delivery or transfer will not violate such
securities laws or rules and regulations and that either the recipient has
tendered to the Company, or the Company or a Subsidiary has withheld, any
federal, state or local tax owed as a result of such issuance, delivery or
transfer, when the Company has a legal liability to satisfy such tax. The
Company shall not be liable for damages due to delay in the issuance, delivery
or transfer of any Award or any security issuable in connection with such Award
or any agreement, instrument or certificate evidencing such Award or security
for any reason whatsoever, including, but not limited to, a delay caused by the
listing requirements of any securities exchange or automated quotation system or
any registration requirements under the Securities Act, the Exchange Act, or
under any other state or federal law, rule or regulation. The Company is under
no obligation to take any action or incur any expense to register or qualify the
issuance, delivery or transfer of any Award or any security issuable in
connection with such Award under applicable securities laws or to perfect any
exemption from such registration or qualification or to list any security on any
securities exchange or automated quotation system. Furthermore, the Company will
have no liability to any person for refusing to issue, deliver or transfer any
Award or any security issuable in connection with such Award if such refusal is
based




                                      -14-
<PAGE>   15

upon the foregoing provisions of this Section 11. As a condition to any
issuance, delivery or transfer of any Award or any security issuable in
connection with such Award, the Company may place legends on any agreement,
instrument or certificate evidencing such Award or security, issue stop transfer
orders with respect thereto and require such agreements or undertakings as the
Company may deem necessary or advisable to assure compliance with applicable
laws or regulations, including, if the Company or its counsel deems it
appropriate, representations from the recipient of such Award or security to the
effect that such recipient is acquiring such Award or security solely for
investment and not with a view to distribution and that no distribution of the
Award or the security will be made unless registered pursuant to applicable
federal and state securities laws, or in the opinion of counsel to the Company,
such registration is unnecessary.

         SECTION 12.  ADJUSTMENTS UPON THE OCCURRENCE OF A RECAPITALIZATION OR 
CORPORATE TRANSACTION

(a)      In the event of a Recapitalization, the number and class of Shares 
subject to this Plan and to each outstanding Award, and the exercise price of
each Award which is based upon Shares, shall (to the extent deemed appropriate
by the Committee) be proportionately adjusted (as determined by the Committee in
its sole discretion) to account for any increase or decrease in the number, or
change in the class, of issued and outstanding Shares of the Company resulting
from such Recapitalization.

(b)      If a Corporate Transaction is consummated and immediately following the
consummation of such Corporate Transaction the Persons who were holders of
Shares immediately prior to the consummation of such Corporate Transaction do
not receive any securities or other property (hereinafter collectively referred
to as "Transactional Consideration") as a result of such Corporate Transaction
and substantially all of such Persons continue to hold the Shares held by them
immediately prior to the consummation of such Corporate Transaction (in
substantially the same proportions relative to each other), the Awards will
remain outstanding and will (subject to, and except as provided in, the other
provisions of this Plan and the Award agreement) continue in full force and
effect in accordance with its terms (without any modification) following the
consummation of the Corporate Transaction.

(c)      If a Corporate Transaction is consummated and immediately following the
consummation of such Corporate Transaction the Persons who were holders of
Shares immediately prior to the consummation of such Corporate Transaction do
receive Transactional Consideration as a result of such Corporate Transaction or
substantially all of such Persons do not continue to hold the Shares held by
them immediately prior to the consummation of such Corporate Transaction (in
substantially the same proportions relative to each other), the terms and
conditions of the Awards will be modified as follows:

(i)      If the documentation pursuant to which a Corporate Transaction will be
consummated provides for the assumption (by the entity issuing Transactional
Consideration to the Persons who were the holders of Shares immediately prior to
the consummation of such Corporate Transaction) of the Awards granted pursuant
to this Plan without any modification or amendment (other than Permitted
Modifications), such Awards will remain outstanding and will continue in full
force and




                                      -15-
<PAGE>   16

effect in accordance with its terms following the consummation of such Corporate
Transaction (subject to such Permitted Modifications).

(ii)     If the documentation pursuant to which a Corporate Transaction will be
consummated does not provide for the assumption by the entity issuing
Transactional Consideration to the Persons who were the holders of Shares
immediately prior to the consummation of such Corporate Transaction of the
Awards granted pursuant to this Plan without any modification or amendment
(other than Permitted Modifications), all vesting restrictions (performance
based or otherwise) applicable to Awards which will not be so assumed will
accelerate and the holders of such Awards may (subject to the expiration of the
term of such Awards) exercise/receive the benefits of such Awards without regard
to such vesting restrictions during the ten (10) day period immediately
preceding the consummation of such Corporate Transaction. For purposes of the
immediately preceding sentence, all performance based goals will be deemed to
have been satisfied in full. The Company will provide each Participant holding
Awards which will not be so assumed with reasonable notice of the termination of
such vesting restrictions and the impending termination of such Awards. Upon the
consummation of such a Corporate Transaction, all unexercised Awards which are
not to be so assumed will automatically terminate and cease to be outstanding.

         Nothing contained in this Section 12 will be deemed to extend the term
         of an Award or to revive any Award which has previously lapsed or been
         cancelled, terminated or surrendered.

         SECTION 13.  AMENDMENT OR TERMINATION OF THIS PLAN

13.1     Amendment of This Plan. Notwithstanding anything contained in this Plan
to the contrary, all provisions of this Plan (including, without limitation, the
maximum number of Shares that may be issued with respect to Awards to be granted
pursuant to this Plan) may at any time or from time to time be modified or
amended by the Board; provided, however, that no Award at any time outstanding
pursuant to this Plan may be modified, impaired or cancelled adversely to the
holder of the Award without the consent of such holder.

13.2     Termination of This Plan. The Board may suspend or terminate this Plan
at any time, and such suspension or termination may be retroactive or
prospective. Termination of this Plan shall not impair or affect any Award
previously granted hereunder and the rights of the holder of the Award shall
remain in effect until the Award has been exercised in its entirety or has
expired or otherwise has been terminated by the terms of such Award.

         SECTION 14.  AMENDMENTS AND ADJUSTMENTS TO AWARDS

         The Committee may amend, modify or terminate any outstanding Award with
the Participant's consent at any time prior to payment or exercise in any manner
not inconsistent with the terms of this Plan, including, without limitation, (i)
to change the date or dates as of which and/or the terms and conditions pursuant
to which (A) a Stock Option becomes exercisable or (B) a Performance Award is
deemed earned, (ii) to amend the terms of any outstanding Award to provide an
exercise price per share which is higher or lower than the then current exercise
price per share of




                                      -16-
<PAGE>   17

such outstanding Award or (iii) to cancel an Award and grant a new Award in
substitution therefor under such different terms and conditions as the Committee
determines in its sole discretion to be appropriate including, but not limited
to, having an exercise price per share which may be higher or lower than the
exercise price per share of the cancelled Award. The Committee may also make
adjustments in the terms and conditions of, and the criteria included in
agreements evidencing Awards in recognition of unusual or nonrecurring events
(including, without limitation, the events described in Section 12 hereof)
affecting the Company, or the financial statements of the Company or any
Affiliate, or of changes in applicable laws, regulations or accounting
principles, whenever the Committee determines that such adjustments are
appropriate to prevent reduction or enlargement of the benefits or potential
benefits intended to be made available pursuant to this Plan.

         SECTION 15.  GENERAL PROVISIONS

15.1     No Limit on Other Compensation Arrangements. Nothing contained in this
Plan shall prevent the Company from adopting or continuing in effect other
compensation arrangements, and such arrangements may be either generally
applicable or applicable only in specific cases. This Plan shall not affect any
other stock option, incentive, or other compensation or benefit plan of the
Company or any Subsidiary, except as may be expressly provided therein.

15.2     Other Awards. The grant of an Award shall not confer upon the recipient
the right to receive any future or other Awards under this Plan or any other
plans of the Company or any Subsidiary, whether or not any awards may be granted
to similarly situated employees, or the right to receive future Awards upon the
same terms or conditions as previously granted.

15.3     No Right to Employment or Continuation of Relationship. Nothing in this
Plan or in any Award, nor the grant of any Award, shall confer upon or be
construed as giving any Participant any right to remain in the employ of the
Company or a Subsidiary or to continue as a Consultant or non-employee Director.
Further, the Company or a Subsidiary may at any time dismiss a Participant from
employment or terminate the relationship of any Consultant or non-employee
Director with the Company or any Subsidiary, free from any liability or any
claim pursuant to this Plan. No Consultant, non-employee Director or employee of
the Company or any Subsidiary shall have any claim to be granted any Award, and
there is no obligation for uniformity of treatment of any Consultant,
non-employee Director or employee of the Company or any Subsidiary or of any
Participants.

15.4     Governing Law. The validity, construction and effect of this Plan and 
any rules and regulations relating to this Plan shall be determined in
accordance with the laws of the State of Texas, without giving effect to the
conflict of laws principles thereof.

15.5     Severability. If any provision of this Plan or any Award is or becomes
or is deemed to be invalid, illegal or unenforceable in any jurisdiction or as
to any individual or Award, or would disqualify this Plan or any Award under any
law deemed applicable by the Committee, such provision shall be construed or
deemed amended to conform to applicable law, or if it cannot be construed or
deemed amended without, in the sole determination of the Committee, materially




                                      -17-
<PAGE>   18

altering the intent of this Plan or the Award, such provision shall be stricken
as to such jurisdiction, individual or Award and the remainder of this Plan and
any such Award shall remain in full force and effect.

15.6     No Fractional Shares. No fractional Shares shall be issued or delivered
pursuant to this Plan or any Award, and the Committee shall determine, in its
sole discretion, whether cash, other securities or other property shall be paid
or transferred in lieu of any fractional Shares or whether such fractional
Shares or any rights thereto shall be cancelled, terminated or otherwise
eliminated.

15.7     Headings. Headings are given to the Sections and Subsections of this 
Plan solely as a convenience to facilitate reference. Such headings shall not be
deemed in any way material or relevant to the construction or interpretation of
this Plan or any provision thereof.

15.8     Gender. If the context requires, words of one gender when used in this
Plan shall include the others and words used in the singular shall include the
plural, and vice versa.

15.9     Transferability of Awards. Awards shall not be transferable otherwise 
than by will or the laws of descent and distribution without the written consent
of the Committee (which may be granted or withheld at the sole discretion of the
Committee). Awards may be exercised, during the lifetime of the holder, only by
the holder. Any attempted assignment, transfer, pledge, hypothecation or other
disposition of an Award contrary to the provisions hereof, or the levy of any
execution, attachment or similar process upon an Award shall be null and void
and without effect.

15.10    Rights of Participants. Except as hereinbefore expressly provided in 
this Plan, any Person to whom an Award is granted shall have no rights by reason
of any subdivision or consolidation of stock of any class or the payment of any
stock dividend or any other increase or decrease in the number of shares of
stock of any class or by reason of any dissolution, liquidation, reorganization,
merger or consolidation or spinoff of assets or stock of another corporation,
and any issue by the Company of shares of stock of any class or securities
convertible into shares of stock of any class shall not affect, and no
adjustment by reason thereof shall be made with respect to, the number or
exercise price of Shares subject to an Award.

15.11    No Limitation Upon the Rights of the Company. The grant of an Award
pursuant to this Plan shall not affect in any way the right or power of the
Company to make adjustments, reclassifications, or changes of its capital or
business structure; to merge, convert or consolidate; to dissolve or liquidate;
or sell or transfer all or any part of its business or assets.

15.12    Date of Grant of an Award. Except as noted in this Section 15.12, the
granting of an Award shall take place only upon the execution and delivery by
the Company and the Participant of a written agreement and neither any other
action taken by the Committee nor anything contained in this Plan or in any
resolution adopted or to be adopted by the Committee, the Board or the
shareholders of the Company shall constitute the granting of an Award pursuant
to this Plan. Solely for purposes of determining the Fair Market Value of the
Shares subject to an Award, such Award




                                      -18-
<PAGE>   19

will be deemed to have been granted as of the date specified by the Committee
notwithstanding any delay which may elapse in executing and delivering the
applicable agreement.

15.13    Tax Withholding. The Company or any Subsidiary shall be entitled to 
deduct from other compensation payable to an employee any sums required by
federal, state, or local tax law to be withheld with respect to the granting or
exercise of a Stock Option or other Award under this Plan. In the alternative,
the Company or any Subsidiary may require the recipient (or other person
exercising the Award) to pay such sums directly to the employer, and neither the
Company or any Subsidiary shall have any obligation to issue any Shares or make
any payment until such payment has been received.

         SECTION 16.  NAMED EXECUTIVE OFFICERS

16.1     Applicability of Section 17. The provisions of this Section 16 shall 
apply only if the Company is a "publicly held corporation" as defined in Section
162(m)(2) of the Code, and then only to those executive officers (i) whose
compensation is required to be reported in the Company's proxy statement
pursuant to Item 402(a)(3)(i) and (ii) (or any successor thereto) of Regulation
S-K (or any successor thereto) under the general rules and regulations under the
Exchange Act and (ii) whose total compensation, including estimated Awards, is
determined by the Committee to possibly be subject to the limitations on
deductions imposed by Section 162(m) of the Code ("Named Executive Officers").
In the event of any inconsistencies between this Section 16 and the other Plan
provisions as they pertain to Named Executive Officers, the provisions of this
Section 16 shall control.

16.2     Establishment of Performance Goals. Awards for Named Executive 
Officers, other than Stock Options and Stock Appreciation Rights, shall be based
on the attainment of certain performance goals. No later than the earlier of (i)
ninety (90) days after the commencement of the applicable fiscal year of the
Company or one of its Subsidiaries or such other award period as may be
established by the Committee ("Award Period") and (ii) the completion of
twenty-five percent (25%) of such Award Period, the Committee shall establish,
in writing, the performance goals applicable to each such Award for Named
Executive Officers. At the time the performance goals are established, their
outcome must be substantially uncertain. In addition, the performance goal must
state, in terms of an objective formula or standard, the method for computing
the amount of compensation payable to the Named Executive Officer if the goal is
obtained. Such formula or standard shall be sufficiently objective so that a
third party with knowledge of the relevant performance results could calculate
the amount to be paid to the subject Named Executive Officer. The material terms
of the performance goals for Named Executive Officers and the compensation
payable thereunder shall be submitted to the shareholders of the Company for
their review and approval if and to the extent required for such compensation to
be deductible pursuant to Section 162(m) (or any successor thereto) of the Code,
and the Treasury Regulations thereunder. Shareholder approval, if necessary,
shall be obtained for such performance goals prior to any Award being paid to
such Named Executive Officer. If shareholder approval is required and not
received with respect to such performance goals, no amount shall be paid to such
Named Executive Officer for such applicable Award Period pursuant to this Plan.




                                      -19-
<PAGE>   20

16.3     Components of Awards. Each Award granted to a Named Executive Officer,
other than Stock Options and Stock Appreciation Rights, shall be based on
performance goals which are sufficiently objective so that a third party having
knowledge of the relevant facts could determine whether the goal was met. Except
as provided in Subsection 16.8 herein, performance measures which may serve as
determinants of Named Executive Officers' Awards shall be limited to the
following measures: earnings per share; return on assets; return on equity;
return on capital; net profit after taxes; net profit before taxes; operating
profits; stock price; and sales or expenses. Within ninety (90) days following
the end of each Award Period, the Committee shall certify in writing that the
performance goals, and any other material terms were satisfied. Thereafter,
Awards shall be made for each Named Executive Officer as determined by the
Committee. The Awards may not vary from the pre-established amount based on the
level of achievement.

16.4     No Mid-Year Change in Awards. Except as provided in Subsections 16.8 
and 16.9 herein, each Named Executive Officer's Awards shall be based
exclusively on the performance measures established by the Committee pursuant to
Subsections 16.2 and 16.3.

16.5     No Partial Award Period Participation. A Named Executive Officer who
becomes eligible to participate in this Plan after performance goals have been
established in an Award Period pursuant to Subsections 16.2 and 16.3 may not
participate in this Plan prior to the next succeeding Award Period, except with
respect to Awards which are Stock Options or Stock Appreciation Rights.

16.6     Performance Goals. Except as provided in Subsection 16.8 herein,
performance goals shall not be changed following their establishment, and Named
Executive Officers shall not receive any payout, except with respect to Awards
which are Stock Options or Stock Appreciation Rights, when the minimum
performance goals are not met or exceeded.

16.7     Individual Performance and Discretionary Adjustments. Except as 
provided in Subsection 16.8 herein, subjective evaluations of individual
performance of Named Executive Officers shall not be reflected in their Awards,
other than Awards which are Stock Options or Stock Appreciation Rights. The
payment of such Awards shall be entirely dependent upon the attainment of the
preestablished performance goals.

16.8     Amendments. No amendment of this Plan with respect to any Named 
Executive Officer may be made which would (i) increase the maximum amount that
can be paid to any one Participant pursuant to this Plan, (ii) change the
specified performance goal for payment of Awards, or (iii) modify the
requirements as to eligibility for participation in this Plan, unless the
Company's shareholders have first approved such amendment in a manner which
would permit the deduction under Section 162(m) (or any successor thereto) of
the Code of such payment in the fiscal year it is paid. The Committee shall
amend this Section 16 and such other provisions as it deems appropriate, to
cause amounts payable to Named Executive Officers to satisfy the requirements of
Section 162(m) (or any successor thereto) and the Treasury regulations
promulgated thereunder.

16.9     Stock Options and Stock Appreciation Rights - Grant Price.  
Notwithstanding any provision of this Plan (including the provisions of this
Section 16) to the contrary, the amount of compensation




                                      -20-
<PAGE>   21

which a Named Executive Officer may receive with respect to Stock Options and
Stock Appreciation Rights which are granted hereunder is based solely on an
increase in the value of the applicable Shares after the date of grant of such
Award. Thus, no Stock Option may be granted hereunder to a Named Executive
Officer with an exercise price less than the Fair Market Value of Shares on the
date of grant. Furthermore, the maximum number of Shares (or cash equivalent
value) with respect to which Stock Options or Stock Appreciation Rights may be
granted hereunder to any Named Executive Officer during any calendar year may
not exceed 1,000,000 Shares, subject to adjustment as provided in Section 12
hereunder.

16.10    Maximum Amount of Compensation. The maximum amount of compensation 
payable as an Award (other than an Award which is a Stock Option or Stock
Appreciation Right) to any Named Executive Officer during any calendar year may
not exceed $1,000,000.

salary of $140,000 for the initial one (1) year of the employment term and such
increase to the base salary during the second year if, in Company's discretion,

payroll deductions and employment taxes beginning October 1, 1997. Employee
shall be responsible for reporting and paying taxes for gross compensation
earned and paid before October 1, 1997.

     (b)  Benefits.  Employee will be entitled to receive additional benefits
and compensation from the Company in such form and to such extent as specified

detail by Employee upon submission of any request for reimbursement, and in a
format and manner consistent with the Company's expense reporting policy.

     4.  Incentive Bonus.  Company agrees to pay Employee a signing bonus of
$65,000, payable upon execution of this Agreement. Employee may be paid

Company, Company grants to Employee options to purchase 250,000 shares of
common stock of Company exercisable at the price of $0.625 per share. Of these
options, 80,000 shares will vest upon execution of this Agreement and will be
exercisable for ten (10) years. The balance of 170,000 shares will vest over

necessary to effect a smooth, efficient and orderly relocation.

     7.  Severance Pay.  In the event Employee's services under this Agreement
are terminated for any reason by Company, except for good cause hereinafter
defined, prior to the end of the employment term, Employee shall be entitled to
an amount equal to the number of remaining months of the term of this Agreement
times the monthly compensation as computed for a total of all base salary. Such
amounts will be paid at date of termination. The Company may terminate the
Agreement fifteen (15) days after written notice to Employee for good cause,
which shall be: (1) Employee's willful and  
<PAGE>   3

material breach of this Agreement; (2) Employee's intentional nonperformance
(continuing for ten (10) days after receipt of written notice of need to cure)
of Employee's material duties and responsibilities hereunder; (3) Employee's
willful dishonesty, fraud or misconduct with respect to the business or affairs
of the Company which materially and adversely affects the operations or
reputation of the Company; or (4) Employee's conviction of a felony crime. In

(August 31, 1999), the Company or Employee may, without cause, terminate
Employee's employment, effective sixty (60) days after written notice is
provided to the other, subject to Company paying to Employee severance pay as
set forth above. If Employee resigns or otherwise terminates Employee's
employment without cause, rather than the Company terminating his employment,
Employee shall receive no severance compensation. If Employee resigns before
the 20th month of the two-year term i.e. April 1, 1999 to become employed by a
company whose business is the same or similar to Company, then Employee shall
pay to Company, at the time of termination, a pro-rata share of the incentive
bonus (identified in paragraph 7 above) computed on the total bonus paid to
Employee divided by 24 months times the remaining months of the initial
two-year term.

     9. Miscellaneous. This instrument supersedes all the other agreements,
either oral or written, between the parties to this Agreement, with respect to
the employment of Employee and contains all the covenants and agreements
between the parties with respect to such service. This Agreement may not be
modified except by written instrument signed by the parties. This Agreement
will be governed by and construed in accordance with the laws of the State of
Texas. This Agreement and any and all rights hereunder shall not be assignable
by Employee, however, nothing herein shall
<PAGE>   4

prohibit Company from assigning this contract or the rights and duties accruing
thereunder to any person, firm or other entity provided that any assignee or
successor to Company shall be bound by the provisions of this Agreement and
such assignment shall not substantially affect the duties of Employee
previously in existence. If any provision of this Agreement shall be declared
inoperative, invalid, illegal or unenforceable, then the remaining provisions
of this Agreement shall continue to be fully operative, effective and
unaffected by such invalidity.

     This Agreement is executed this 18th day of September, 1997 effective
September 1, 1997 for purposes of calculating a commencement date of the
two-year term.

          (iii)     The Shares for which it hereby subscribes will be acquired
                    for investment and not with the view toward resale or

          (iv)      It has received no representations or warranties from the
                    Company, or its employees or agents, as to the viability of
                    the Company's operations or its capitalization other than
                    the fact that the Company has entered into contracts with
                    Prodigy Services Corporation ("Transaction Documents"). As

<PAGE>   2
          (v)       It is able to bear the economic risk of the investment in
                    the Shares and it has sufficient net worth to sustain a loss
                    of the entire investment in the Company without economic
                    hardship if such a loss should occur.

          (vi)      It confirms that all documents, records and books pertaining
                    to its proposed investment in the Company which it has
                    requested have been made available to it.

          (vii)     It has had an opportunity to ask questions of and receive
                    satisfactory answers from William R. Wilson, Kwok Li, the
                    Company, or any person or persons acting on behalf of the
                    Company, concerning the terms and conditions of this
                    investment, and all such questions have been answered to the
                    full satisfaction of Subscriber.

          (viii)    Subscriber represents that it has made other investments of
                    a similar nature and, by reason of its business and
                    financial experience and of the business and financial
                    experience of those persons it has retained to advise it
                    with respect to its investment in the Company, has acquired
                    the capacity to protect its own interest in investments of
                    this nature.

          (ix)      Its representatives have visited with Kwok Li regarding the
                    technical aspects of the proposed operations of the Company.

          (x)       It acknowledges that the Company has been capitalized as of
                    the date of this Subscription Agreement, and prior to
                    acceptance of this Subscription Agreement, with $30,500,000
                    U. S. at a price of $0.625 U. S. per Share for 28,800,000

                    received an aggregate of 28,000,000 Shares for their
                    contribution of services to the organization of the Company
                    and their negotiation of the transaction with Prodigy
                    Services Corporation. Assuming the issuance of all Shares

          (xi)      It acknowledges that the Board of Directors of the Company
                    may issue additional Shares for such consideration as the
                    Board of Directors deems adequate. The Shares do not have
                    preemptive rights; therefore, in the event of such
                    issuances, the Subscriber's percentage ownership in the
                    Company as stated above would be diluted.

meaning and legal consequences of the representations and warranties in
paragraph C hereof, and it hereby agrees to indemnify and hold harmless the
Company, each shareholder thereof and their respective officers, directors,
shareholders, agents and employees from and against any and all loss, damage or
liability due to or arising out of a breach of any such representation or
warranties. Notwithstanding the foregoing, however, no representation, warranty,
acknowledgement or agreement made herein by Subscriber shall in any manner be
deemed to constitute a waiver of any rights granted to Subscriber under federal
or state securities laws. The representations and warranties set forth herein
shall survive the date upon which the Subscriber is admitted as a shareholder of
the Company.

     E.  Limitation on Transfer of Shares.  Subscriber acknowledges that it is
aware that there are substantial restrictions on the transferability of the
Shares. Since the Shares will not be, and Subscriber has no right to require
that they be, registered under the 1933 Act, as amended, or any other
securities laws of any jurisdiction (collectively, the "Acts"), the Shares may
not be, and Subscriber agrees that they shall not be, sold, transferred,
pledged or hypothecated unless such sale is exempt from registration under the
Acts. Subscriber further acknowledges that the Shares may not be sold and the
purchaser substituted as a shareholder in the Company without the express
consent of the Company. Subscriber also acknowledges that it shall be
responsible for compliance with all conditions on transfer imposed by any blue
sky or securities law administrator and for any expenses incurred by the
Company for legal or accounting services in connection with reviewing such a
proposed transfer.

     F.  Compliance with Regulation D.  Subscriber understands and agrees that
the following restrictions and limitations are applicable to its purchase and
resale, pledge, hypothecation or other transfer of the Shares pursued to

          (i)       Subscriber agrees that the Shares shall not be sold,
                    pledged, hypothecated or otherwise transferred unless
                    either: (1) the Shares are registered under the 1933 Act, as
                    amended, and applicable state securities law; or, (2) the
                    sale of the Shares is exempt thereon;

          (ii)      a legend has been or will be placed on any certificate(s) or
                    other document(s) evidencing the Shares is substantially the
                    following form:

          THE SECURITIES REPRESENTED BY THIS INSTRUMENT OR DOCUMENT HAVE BEEN
          ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY
          STATE, SUCH SECURITIES MAY NOT BE SOLD, PLEDGED, HYPOTHECATED OR
          OTHERWISE TRANSFERRED AT ANY TIME WHATSOEVER, EXCEPT UPON
          REGISTRATION, OR UPON DELIVERY TO THE COMPANY OF ANY OPINION OF
          COUNSEL SATISFACTORY TO THE COMPANY THAT REGISTRATION IS NOT REQUIRED
          FOR SUCH TRANSFER OR SUBMISSION TO THE COMPANY OF




                                      -3-
<PAGE>   4
          SUCH EVIDENCE AS MAY BE SATISFACTORY TO THE COMPANY TO THE EFFECT THAT
          ANY SUCH TRANSFER SHALL NOT BE IN VIOLATION OF THE SECURITIES ACT OF
          1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS OR ANY RULE OR
          REGULATION PROMULGATED THEREUNDER.

     G.   The following exhibits are attached hereto:

         The undersigned hereby acknowledges receipt and review of the
Prospectus dated __________, 1998 (the "Prospectus") of Splitrock Services,
Inc. (the "Company") and this Letter of Transmittal (the "Letter of
Transmittal"), which together describe the Company's offer (the "Exchange
Offer") to exchange its 11 3/4% Series B Senior Notes due 2008 (the "Exchange
Notes"), which have been registered under the Securities Act of 1933, as
amended (the "Securities Act"), pursuant to a Registration Statement of which
the Prospectus is a part, for a like principal amount of its issued and
outstanding 11 3/4% Senior Notes due 2008 (the "Original Notes").  Capitalized
terms used but not defined herein have the respective meaning given to them in
the Prospectus.

         The Company reserves the right, at any time or from time to time, to
extend the Exchange Offer at its discretion, in which event the term
"Expiration Date" shall mean the latest time and date in which the Exchange
Offer is extended.  The Company shall notify the holders of the Original Notes
of any extension by oral or written notice prior to 9:00 A.M., New York City
time, on the next business day after the previously scheduled Expiration Date.

         This Letter of Transmittal is to be used by a Holder of Original Notes
either if Original Notes are to be forwarded herewith or if delivery of
Original Notes, if available, is to be made by book-entry transfer to the
account maintained by the Exchange Agent at The Depository Trust Company (the
"Book-Entry Transfer Facility") pursuant to the procedures set forth in the
Prospectus under the caption "The Exchange Offer--Book-Entry Transfer."
Holders of Original Notes whose Original Notes are not immediately available,
or who are unable to deliver their Original Notes and all other documents
required by this Letter of Transmittal to the Exchange Agent on or prior to the
Expiration Date, or who are unable to complete the procedure for book-entry
transfer on a timely basis, must tender their Original Notes according to the
guaranteed delivery procedures set forth in the Prospectus under the caption
"The Exchange Offer- Guaranteed Delivery Procedures."  See Instruction 2.
Delivery of documents to the Book-Entry Transfer Facility does not constitute
delivery to the Exchange Agent.

         The term "Holder" with respect to the Exchange Offer means any person
in whose name Original Notes are registered on the books of the Company or any
other person who has obtained a properly completed bond power from the
registered Holder.  The undersigned has completed, executed and delivered this
Letter of Transmittal to indicate the action the undersigned desires to take
with respect to the Exchange Offer.  Holders who wish to tender their Original
Notes must complete this Letter of Transmittal in its entirety.

         The undersigned has checked the appropriate boxes below and signed
this Letter of Transmittal to indicate the action the undersigned desires to
take with respect to the Exchange Offer.

                    NOTE:  SIGNATURES MUST BE PROVIDED BELOW
              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY


Ladies and Gentlemen:

         Subject to the terms and conditions of the Exchange Offer, the
undersigned hereby tenders to the Company for exchange the principal amount of
Original Notes indicated above.  Subject to and effective upon the acceptance
for exchange of the principal amount of Original Notes tendered in accordance
with this Letter of Transmittal, the undersigned hereby exchanges, assigns and
transfers to the Company all right, title and interest in and to the Original
Notes tendered for exchange hereby.  The undersigned hereby irrevocably
constitutes and appoints the Exchange Agent, the agent and attorney-in-fact of
the undersigned (with full knowledge that the Exchange Agent also acts as the
agent of the Company in connection with the Exchange Offer) with respect to the
tendered Original Notes with full power of substitution to (i) deliver such
Original Notes, or transfer ownership of such Original Notes on the account
books maintained by the Book-Entry Transfer Facility, to the Company and
deliver all accompanying evidences of transfer and authenticity, and (ii)
present such Original Notes for transfer on the books of the Company and
receive all benefits and otherwise exercise all rights of beneficial ownership
of such Original Notes, all in accordance with the terms of the Exchange Offer.
The power of attorney granted in this paragraph shall be deemed to be
irrevocable and coupled with an interest.

         The undersigned hereby represents and warrants that the undersigned
has full power and authority to tender, exchange, assign and transfer the
Original Notes tendered hereby and to acquire the Exchange Notes issuable upon
the exchange of such tendered Original Notes, and that the Company will acquire
good and unencumbered title thereto, free and clear of all liens, restrictions,
charges and encumbrances and not subject to any adverse claim, when the same
are accepted for exchange by the Company.

         The undersigned acknowledges that this Exchange Offer is being made in
reliance upon interpretations contained in no-action letters issued to third
parties by the staff of the Securities and Exchange Commission (the
"Commission") that the Exchange Notes issued in exchange for the Original Notes
pursuant to the Exchange Offer may be offered for resale, resold and otherwise
transferred by Holders thereof (other than any such Holder that is an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act), without compliance with the registration and prospectus delivery
provisions of the Securities Act, provided that such Exchange Notes are
acquired in the ordinary course of such Holders' business and such Holders are
not engaging in and do not intend to engage in a distribution of the Exchange
Notes and have no arrangement or understanding with any person to participate
in a distribution of such Exchange Notes.  The undersigned hereby further
represents to the Company that (i) any Exchange Notes acquired in exchange for
Original Notes tendered hereby are being acquired in the ordinary course of
business of the person receiving such Exchange Notes, whether or not the
undersigned, (ii) neither the undersigned nor any such other person is engaging
in or intends to engage in a distribution of the Exchange Notes, (iii) neither
the undersigned nor any such other person has an arrangement or understanding
with any person to participate in the distribution of such Exchange Notes, (iv)
neither the Holder nor any such other person is an "affiliate," as defined in
Rule 405 under the Securities Act, of the Company or, if it is an affiliate, it
will comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable, and (v) if the undersigned is a
broker-dealer, such person has acquired the Original Notes as a result of
market-making activities or other trading activities.

         If the undersigned or the person receiving the Exchange Notes is a
broker-dealer that is receiving Exchange Notes for its own account in exchange
for Original Notes that were acquired as a result of market-making activities
or other trading activities, the undersigned acknowledges that it or such other
person will deliver a prospectus in connection with any resale of such Exchange
Notes; however, by so acknowledging and by delivering a prospectus, the
undersigned will not be deemed to admit that the undersigned or such other
person is an "underwriter" within the meaning of the Securities Act.  The
undersigned acknowledges that if the undersigned is participating in the
Exchange Offer for the purpose of distributing the Exchange Notes (i) the
undersigned cannot rely on the position of the staff of the Commission in
certain no-action letters and, in the absence of an exemption therefrom, must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with a secondary resale transaction of the
Exchange Notes, in which case the registration statement must contain the
selling security holder information





                                       5
<PAGE>   6
required by Item 507 or Item 508, as applicable, of Regulation S-K of the
Commission, and (ii) failure to comply with such requirements in such instance
could result in the undersigned incurring liability under the Securities Act
for which the undersigned is not indemnified by the Company.

         If the undersigned or the person receiving the Exchange Notes is an
"affiliate" (as defined in Rule 405 under the Securities Act), the undersigned
represents to the Company that the undersigned understands and acknowledges
that the Exchange Notes may not be offered for resale, resold or otherwise
transferred by the undersigned or such other person without registration under
the Securities Act or an exemption therefrom.

         The undersigned will, upon request, execute and deliver any additional
documents deemed by the Exchange Agent or the Company to be necessary or
desirable to complete the exchange, assignment and transfer of the Original
Notes tendered hereby, including the transfer of such Original Notes on the
account books maintained by the Book-Entry Transfer Facility.

         For purposes of the Exchange Offer, the Company shall be deemed to
have accepted for exchange validly tendered Original Notes when, as and if the
Company gives oral or written notice thereof to the Exchange Agent.  Any
tendered Original Notes that are not accepted for exchange pursuant to the
Exchange Offer for any reason will be returned, without expense, to the
undersigned at the address shown below or at a different address as may be
indicated herein under "Special Delivery Instructions" as promptly as
practicable after the Expiration Date.

         All authority conferred or agreed to be conferred by this Letter of
Transmittal shall survive the death, incapacity or dissolution of the
undersigned, and every obligation of the undersigned under this Letter of
Transmittal shall be binding upon the undersigned's heirs, personal
representatives, successors and assigns.

         The undersigned acknowledges that the Company's acceptance of properly
tendered Original Notes pursuant to the procedures described under the caption
"The Exchange Offer-Procedures for Tendering" in the Prospectus and in the
instructions hereto will constitute a binding agreement between the undersigned
and the Company upon the terms and subject to the conditions of the Exchange
offer.

         Unless otherwise indicated under "Special Issuance Instructions,"
please issue the Exchange Notes issued in exchange for the Original Notes
accepted for exchange and return any Original Notes not tendered or not
exchanged, in the name(s) of the undersigned.  Similarly, unless otherwise
indicated under "Special Delivery Instructions," please mail or deliver the
Exchange Notes issued in exchange for the Original Notes accepted for exchange
and any Original Notes not tendered or not exchanged (and accompanying
documents, as appropriate) to the undersigned at the address shown below the
undersigned's signatures.  In the event that both "Special Issuance
Instructions" and "Special Delivery Instructions" are completed, please issue
the Exchange Notes issued in exchange for the Original Notes accepted for
exchange in the name(s) of, and return any Original Notes not tendered or not
exchanged to, the person(s) so indicated.  The undersigned recognizes that the
Company has no obligation pursuant to the "Special Issuance Instructions" and
"Special Delivery Instructions" to transfer any Original Notes from the name of
the registered holder(s) thereof if the Company does not accept for exchange
any of the Original Notes so tendered for exchange.

                         FORMING PART OF THE TERMS AND
                        CONDITIONS OF THE EXCHANGE OFFER


         1.      DELIVERY OF THIS LETTER OF TRANSMITTAL AND ORIGINAL NOTES OR
BOOK-ENTRY CONFIRMATIONS.  All physically delivered Original Notes or any
confirmation of a book-entry transfer to the Exchange Agent's account at the

executed copy of this Letter of Transmittal or facsimile hereof, and any other
documents required by this Letter of Transmittal, must be received by the

City time, on the Expiration Date.  The method of delivery of the tendered
Original Notes, this Letter of Transmittal and all other required documents to

otherwise provided below, the delivery will be deemed made only when actually
received or confirmed by the Exchange Agent.  Instead of delivery by mail, it
is recommended that the Holder use an overnight or hand delivery service.  In
all cases, sufficient time should be allowed to assure delivery to the Exchange
Agent before the Expiration Date.  No Letter of Transmittal or Original Notes
should be sent to the Company.

         2.      GUARANTEED DELIVERY PROCEDURES.  Holders who wish to tender
their Original Notes and (a) whose Original Notes are not immediately
available, or (b) who cannot deliver their Original Notes, this Letter of
Transmittal or any other documents required hereby to the Exchange Agent prior
to the Expiration Date or (c) who are unable to complete the procedure for
book-entry transfer on a timely basis, must tender their Original Notes
according to the guaranteed delivery procedures set forth in the Prospectus.
Pursuant to such procedures:  (i) such tender must be made by or through a firm
which is a member of a registered national securities exchange or of the
National Association of Securities Dealers Inc. or a commercial bank or a trust
company having an office or correspondent in the United States (an "Eligible
Institution"); (ii) prior to the Expiration Date, the Exchange Agent must have
received from the Eligible Institution a properly completed and duly executed
Notice of Guaranteed Delivery (by facsimile transmission, mail or hand
delivery) setting forth the name and address of the Holder of the Original
Notes, the registration number(s) of such Original Notes and the principal
amount of Original Notes tendered, stating that the tender is being made
thereby and guaranteeing that, within three (3) New York Stock Exchange, Inc.
("NYSE") trading days after the Expiration Date, this Letter of Transmittal (or
facsimile hereof) together with the Original Notes (or a Book-Entry
Confirmation) in proper form for transfer will be received by the Exchange
Agent; and (iii) the certificates for all physically tendered shares of
Original Notes, in proper form for transfer, or Book-Entry Confirmation, as the
case may be, and all other documents required by this Letter of Transmittal are
received by the Exchange Agent within three (3) NYSE trading days after the
date of execution of the Notice of Guaranteed Delivery.

         Any Holder of Original Notes who wishes to tender Original Notes
pursuant to the guaranteed delivery procedures described above must ensure that
the Exchange Agent receives the Notice of Guaranteed Delivery prior to 5:00
p.m., New York City time, on the Expiration Date.  Upon request of the Exchange
Agent, a Notice of Guaranteed Delivery will be sent to Holders who wish to
tender their Original Notes according to the guaranteed delivery procedures set
forth above.

         See "The Exchange Offer-Guaranteed Delivery Procedures" section of the
Prospectus.

         3.      TENDER BY HOLDER.  Only a Holder of Original Notes may tender
such Original Notes in the Exchange Offer.  Any beneficial Holder of Original
Notes who is not the registered Holder and who wishes to tender should arrange
with the registered Holder to execute and deliver this Letter of Transmittal on
the beneficial Holder's behalf or must, prior to completing and executing this
Letter of Transmittal and delivering the beneficial Holder's Original Notes,
either make appropriate arrangements to register ownership of the Original
Notes in such Holder's name or obtain a properly completed bond power from the
registered Holder.

         4.      PARTIAL TENDERS.  Tenders of Original Notes will be accepted
only in integral multiples of $1,000.  If less than the entire principal amount
of any Original Notes is tendered, the tendering Holder should fill in the
principal amount tendered in the fourth column of the box entitled.
"Description of Original Notes Tendered" above.  The entire principal amount of
Original Notes delivered to the Exchange Agent will be deemed to have been
tendered unless





                                       9
<PAGE>   10
otherwise indicated.  If the entire principal amount of all Original Notes is
not tendered, then Original Notes for the principal amount of Original Notes
not tendered and Exchange Notes issued in exchange for any Original Notes
accepted will be sent to the Holder at the Holder's registered address, unless
a different address is provided in the appropriate box on this Letter of
Transmittal, promptly after the Original Notes are accepted for exchange.

         5.      SIGNATURES ON THIS LETTER OF TRANSMITTAL; BOND POWERS AND
ENDORSEMENTS; MEDALLION GUARANTEE OF SIGNATURES.  If this Letter of Transmittal
(or facsimile hereof) is signed by the record Holder(s) of the Original Notes
tendered hereby, the signature must correspond with the name(s) as written on
the face of the Original Notes without alteration, enlargement or any change
whatsoever.  If this Letter of Transmittal is signed by a participant in the
Book- Entry Transfer Facility, the signature must correspond with the name as
it appears on the security position listing as the Holder of the Original
Notes.

         If this Letter of Transmittal (or facsimile hereof) is signed by the
registered Holder or Holders of Original Notes listed and tendered hereby and
the Exchange Notes issued in exchange therefor is to be issued (or any
untendered principal amount of Original Notes is to be reissued) to the
registered Holder, the Holder need not and should not endorse any tendered
Original Notes, nor provide a separate bond power.  In any other case, such
Holder must either properly endorse the Original Notes tendered or transmit a
properly completed separate bond power with this Letter of Transmittal, with
the signatures on the endorsement or bond power guaranteed by an Eligible
Institution.

         If this Letter of Transmittal (or facsimile hereof) is signed by a
person other than the registered Holder or Holders of any Original Notes
listed, such Original Notes must be endorsed or accompanied by appropriate bond
powers, in each case signed as the name of the registered Holder or Holders
appears on the Original Notes.

         If this Letter of Transmittal (or facsimile hereof) or any Original
Notes or bond powers are signed by trustees, executors, administrators,
guardians, attorneys-in-fact, or officers of corporations or others acting in a
fiduciary or representative capacity, such persons should so indicate when
signing, and, unless waived by the Company, evidence satisfactory to the
Company of their authority to so act must be submitted with this Letter of
Transmittal.

         Endorsements on Original Notes or signatures on bond powers required
by this Instruction 5 must be guaranteed by an Eligible Institution.

         No signature guarantee is required if (i) this Letter of Transmittal
is signed by the registered Holder(s) of the Original Notes tendered herewith
(or by a participant in the Book-Entry Transfer Facility whose name appears on
a security position listing as the owner of the tendered Original Notes) and
the issuance of Exchange Notes (and any Original Notes not tendered or not
accepted) are to be issued directly to such registered Holder(s) (or, if signed
by a participant in the Book-Entry Transfer Facility, any Exchange Notes or
Original Notes not tendered or not accepted are to be deposited to such
participant's account at such Book-Entry Transfer Facility) and neither the box
entitled "Special Delivery Instructions" nor the box entitled "Special
Registration Instructions" has been completed, or (ii) such Original Notes are
tendered for the account of an Eligible Institution.  In all other cases, all
signatures on this Letter of Transmittal must be guaranteed by an Eligible
Institution.

         6.      SPECIAL REGISTRATION AND DELIVERY INSTRUCTIONS.  Tendering
Holders should indicate, in the applicable box or boxes, the name and address
(or account at the Book-Entry Transfer Facility) to which Exchange Notes or
substitute Original Notes for principal amounts not tendered or not accepted
for exchange are to be issued or sent, if different from the name and address
of the person signing this Letter of Transmittal.  In the case of issuance in a
different name, the taxpayer identification or social security number of the
person named must also be indicated.

         7.      TRANSFER TAXES.  The Company will pay all transfer taxes, if
any, applicable to the exchange of Original Notes pursuant to the Exchange
offer.  If, however, Exchange Notes or Original Notes for principal amounts not
tendered or accepted for exchange are to be delivered to, or are to be
registered or issued in the name of, any person other than the registered
Holder of the Original Notes tendered hereby, or if tendered Original Notes are
registered in the name of any person other than the person signing this Letter
of Transmittal, or if a transfer tax is imposed for any reason other than the
exchange of Original Notes pursuant to the Exchange offer, then the amount of
any such transfer taxes (whether imposed on the registered Holder or any other
persons) will be payable by the tendering Holder.  If





                                       10
<PAGE>   11
satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted with this Letter of Transmittal, the amount of such transfer taxes
will be billed directly to such tendering Holder.

         EXCEPT AS PROVIDED IN THIS INSTRUCTION 7, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE ORIGINAL NOTES LISTED IN THIS LETTER
OF TRANSMITTAL.

         8.      TAX IDENTIFICATION NUMBER.  Federal income tax law requires
that a holder of any Original Notes which are accepted for exchange must
provide the Company (as payor) with its correct taxpayer identification number
("TIN"), which, in the-case of a holder who is an individual is his or her
social security number.  If the Company is not provided with the correct TIN,
the Holder may be subject to a $50 penalty imposed by the Internal Revenue
Service. (If withholding results in an over-payment of taxes, a refund may be
obtained.) Certain Holders (including, among others, all corporations and
certain foreign individuals) are not subject to these backup withholding and
reporting requirements.  See the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for additional
instructions.

         To prevent backup withholding, each tendering Holder must provide such
holder's correct TIN by completing the Substitute Form W-9 set forth herein,
certifying that the TIN provided is correct (or that such holder is awaiting a
TIN), and that (i) the Holder has not been notified by the Internal Revenue
Service that such Holder is subject to backup withholding as a result of
failure to report all interest or dividends or (ii) the Internal Revenue
Service has notified the Holder that such Holder is no longer subject to backup
withholding.  If the Original Notes are registered in more than one name or are
not in the name of the actual owner, see the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9," for
information on which TIN to report.

         The Company reserves the right in its sole discretion to take whatever
steps are necessary to comply with the Company's obligation regarding backup
withholding.

         9.      VALIDITY OF TENDERS.  All questions as to the validity, form,
eligibility (including time of receipt), and acceptance of tendered Original
Notes will be determined by the Company, in its sole discretion, which
determination will be final and binding.  The Company reserves the right to
reject any and all Original Notes not validly tendered or any Original Notes,
the Company's acceptance of which would, in the opinion of the Company or its
counsel, be unlawful.  The Company also reserves the right to waive any
conditions of the Exchange Offer or defects or irregularities in tenders of
Original Notes as to any ineligibility of any holder who seeks to tender
Original Notes in the Exchange Offer.  The interpretation of the terms and
conditions of the Exchange Offer (includes this Letter of Transmittal and the
instructions hereto) by the Company shall be final and binding on all parties.
Unless waived, any defects or irregularities in connection with tenders of
Original Notes must be cured within such time as the Company shall determine.
The Company will use reasonable efforts to give notification of defects or
irregularities with respect to tenders of Original Notes, but shall not incur
any liability for failure to give such notification.

         10.     WAIVER OF CONDITIONS.  The Company reserves the absolute right
to waive, in whole or part, any of the conditions to the Exchange Offer set
forth in the Prospectus.

         11.     NO CONDITIONAL TENDER.  No alternative, conditional, irregular
or contingent tender of Original Notes on transmittal of this Letter of
Transmittal will be accepted.

         12.     MUTILATED, LOST, STOLEN OR DESTROYED ORIGINAL NOTES.  Any
Holder whose Original Notes have been mutilated, lost, stolen or destroyed
should contact the Exchange Agent at the address indicated above for further
instructions.

         13.     REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Requests for
assistance or for additional copies of the Prospectus or this Letter of
Transmittal may be directed to the Exchange Agent at the address or telephone
number set forth on the cover page of this Letter of Transmittal.  Holders may
also contact their broker, dealer, commercial bank, trust company or other
nominee for assistance concerning the Exchange Offer.

NOTES; RETURN OF ORIGINAL NOTES.  Subject to the terms and conditions of the
Exchange Offer, the Company will accept for exchange all validly tendered
Original Notes as soon as practicable after the Expiration Date and will issue
Exchange Notes therefor as soon as practicable thereafter.  For purposes of the
Exchange Offer, the Company shall be deemed to have accepted tendered Original
Notes when, as and if the Company has given written and oral notice thereof to
the Exchange Agent.  If any tendered Original Notes are not exchanged pursuant
to the Exchange Offer for any reason, such unexchanged Original Notes will be
returned, without expense, to the undersigned at the address shown above (or
credited to the undersigned's account at the Book-Entry Transfer Facility
designated above) or at a different address as may be indicated under the box
entitled "Special Delivery Instructions."

         15.     WITHDRAWAL.  Tenders may be withdrawn only pursuant to the
limited withdrawal rights set forth in the Prospectus under the caption "The

HOW TO OBTAIN A TIN

If you don't have a taxpayer identification number or you don't know your
number, obtain Form SS-5, Application for a Social Security Number Card for
individuals, or Form SS-4, Application for Employer Identification Number (for
business and other entities), or Form W-7, Application for IRS Individual
Taxpayer Identification Number (for certain resident aliens), at the local
office of the Social Security Administration or the Internal Revenue Service
and apply for a number.

If You return the Substitute Form W-9 with the "Awaiting TIN" box checked in
Part 3, you must provide the payer with a Certificate of Awaiting Taxpayer
Identification Number and, within 60 days, a TIN.  If you do not provide the
TIN by the date of payment, 31% of all reportable payments will be withheld.
If your certified TIN is received within the 60-day period and you were not
subject to backup withholding during that period, the amounts withheld will be
refunded to you.  If no certified TIN is provided to the payer within 60 days,
the amounts withheld will be paid to the IRS.

AS SOON AS YOU RECEIVE YOUR TIN, COMPLETE ANOTHER SUBSTITUTE FORM W-9, INCLUDE
YOUR TIN, SIGN AND DATE THE FORM, AND GIVE IT TO THE PAYER.

For interest, dividends and broker transactions, you must sign the
certification or backup withholding will apply.  If you are subject to backup
withholding and you are merely providing your correct TIN to a payer, you must

WRITE "EXEMPT" ON THE FACE OF THE FORM IN PART 2, SIGN AND DATE THE FORM, AND
RETURN IT TO THE PAYER.

Certain payments, other than interest, dividends and patronage dividends that
are not subject to information reporting are also not subject to backup
withholding.  For details, see sections 6041, 6041A(a), 6042, 6044, 6045, 6049,
6050A and 605ON and the regulations thereunder.

PRIVACY ACT NOTICE.  Section 6109 requires most recipients of dividend,
interest or other payments to give their correct TIN to payers who must report
the payments to the IRS.  The IRS uses the numbers for identification purposes
and to help verify the accuracy of tax returns.  The IRS may also provide this
information to the Department of Justice for civil and criminal litigation and
to cities, states and the District of Columbia to carry out their tax laws.
Payers must be given the TIN whether or not recipients are required to file tax
returns.  Payers must generally withhold 31% of taxable interest, dividend and
certain other payments to a payee who does not furnish a taxpayer
identification number to a payer.  Certain penalties may also apply.

PENALTIES

(1) PENALTY FOR FAILURE TO FURNISH TIN.--If you fail to furnish your correct
    TIN to a payer, you are subject to a penalty of $50 for each such failure
    unless your failure is due to reasonable cause and not to willful neglect.

(2) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.--If you
    make a false statement with no reasonable basis which results in no
    imposition of-backup withholding, you are subject to a penalty of $500.
