(1) The "Amount to be registered" with respect to the 13 1/4% Senior Discount
    Notes due 2005, Series B (the "Exchange Notes") represents the maximum
    amount at maturity of Exchange Notes that may be issued pursuant to the
    exchange offer described in the Registration Statement. The 13 1/4% Senior
    Discount Notes due 2005, Series A (the "Original Notes"), into which the

    to Rule 457 under the Securities Act.
   
(3) The registration fee for the Exchange Notes offered hereby, $20,505.45, is
    calculated under Rule 457(f)(2) of the Securities Act as follows: the
    product of .000295 and $69,510,000, one third of the aggregate principal
    amount at maturity of the outstanding Original Notes, that may be tendered
    to the Registrant (which has an accumulated capital deficit) in exchange

 OFFER TO EXCHANGE $1,000 IN PRINCIPAL AMOUNT OF 13 1/4% SENIOR DISCOUNT NOTES
 DUE 2005, SERIES B, FOR EACH $1,000 IN PRINCIPAL AMOUNT OF OUTSTANDING 13 1/4%
SENIOR DISCOUNT NOTES DUE 2005, SERIES A, THAT WERE ISSUED AND SOLD IN RELIANCE
  ON EXEMPTIONS FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED
                                          
                                  -----------
  WAM!NET, a Minnesota corporation ("WAM!NET" or the "Company"), hereby offers
to exchange (the "Exchange Offer") $208,530,000 in aggregate principal amount
at maturity of its 13 1/4% Senior Discount Notes due 2005, Series B (the
"Exchange Notes") for $208,530,000 in aggregate principal amount at maturity of
its 13 1/4% Senior Discount Notes due 2005, Series A (the "Original Notes" and,
together with the Exchange Notes, the "Notes"), that were issued and sold in
reliance on exemptions from registration under the Securities Act of 1933, as
amended (the "Securities Act").
   
  The terms of the Exchange Notes are substantially similar (including
principal amount, interest rate, maturity and ranking) to the terms of the
Original Notes for which they may be exchanged pursuant to the Exchange Offer,
except that the Exchange Notes (i) are freely transferable by holders thereof
(except as provided below) and are issued without any covenant regarding their
registration. The Exchange Notes will be issued under the indenture governing
the Original Notes. The Exchange Notes will be, and the Original Notes are,
general unsecured obligations of the Company and, as such, will rank pari passu
in right of payment with all existing and future unsecured and unsubordinated
Indebtedness (as defined herein) of the Company. The Exchange Notes will be,
and the Original Notes are, effectively subordinated in right of payment to all
secured Indebtedness of the Company to the extent of the value of the assets
securing such Indebtedness. As of March 31, 1998, the Company had outstanding
approximately $10.4 million of secured Indebtedness (consisting principally of
equipment financing), which would have effectively ranked senior in right of
payment to the Notes, no Indebtedness which would have ranked pari passu in
right of payment with the Notes and $25.9 million of Indebtedness which would
have been subordinated in right of payment to the Notes. The Indenture (as
defined herein) does not limit the amount of secured Permitted Equipment
Financing (as defined herein) that may be incurred by the Company. The Exchange
Notes will be, and the Original Notes are, fully and unconditionally guaranteed
on an unsecured and unsubordinated basis by all Material Restricted
Subsidiaries (as defined herein), which guarantees may be released under
certain circumstances; provided, however, that a Material Restricted Subsidiary
that is a Foreign Subsidiary (as defined herein) cannot become a Subsidiary
Guarantor (as defined herein) if by doing so it would violate applicable law of
its jurisdiction of organization or incorporation. As of the date hereof, the
Company does not have any Material Restricted Subsidiaries that are Subsidiary
Guarantors, and no Subsidiary (as defined herein) of the Company has any
Indebtedness. The Notes are effectively subordinated to the indebtedness,
including trade payables, of the Company's Subsidiaries that are not Subsidiary
Guarantors, which, as of March 31, 1998, was approximately $0.9 million. For a
complete description of the terms of the Exchange Notes, including provisions
relating to the ability of the Company to create indebtedness that is senior or
pari passu to the Exchange Notes, see "Description of the Notes." There will be
no cash proceeds to the Company from the Exchange Offer.     
   
  For each Original Note accepted for exchange the holder of such Original Note
will receive an Exchange Note having a principal amount equal to that of the
surrendered Original Note. Original Notes accepted for exchange will cease to
accrete value from and after the date of consummation of the Exchange Offer.
Holders of Original Notes whose Original Notes are accepted for exchange will
not receive any payment of accreted value on such Original Notes. Original
Notes that remain outstanding following the consummation of the Exchange Offer
will continue to accrete value from the Issue Date (as defined herein), as
provided in the Original Notes. The accreted value of the Exchange Notes will
be calculated from the Issue Date, and will be identical to that of the
Original Notes.     
 
  The Original Notes were originally issued and sold on March 5, 1998 (the
"Issue Date") in transactions exempt from registration under the Securities
Act, in reliance upon the exemption provided in Section 4(2) of the Securities
Act and Rule 144A of the Securities Act and pursuant to offers and sales that
occurred outside the United States within the meaning of Regulation S of the
Securities Act (collectively, the "Initial Offering"). Accordingly, the
Original Notes may not be reoffered, resold or otherwise pledged, hypothecated
or transferred in the United States unless so registered or unless an
applicable exemption from the registration requirements of the Securities Act
is available. Based upon its view of interpretations provided to third parties
by the Staff (the "Staff") of the Securities and Exchange Commission (the
"Commission"), the Company believes that the Exchange Notes issued pursuant to
the Exchange Offer in exchange for the Original Notes may be offered for
resale, resold and otherwise transferred by holders thereof (other than any
holder or any such other person which

SHOULD BE CONSIDERED BY PARTICIPANTS IN THE EXCHANGE OFFER.

THESE SECURITIES  HAVE NOT BEEN APPROVED  OR DISAPPROVED BY THE  SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES 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.

is (i) an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act (an "Affiliate"), (ii) a broker-dealer who acquired Original
Notes directly from the Company or (iii) a broker-dealer who acquired Original
Notes as a result of market making or other trading activities) 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 business of such holder and any beneficial owner, and such holders
are not engaged in, and do not intend to engage in, and have no arrangement or
understanding with any person to participate in, a distribution of such
Exchange Notes. Each broker-dealer who acquired Original Notes directly from
the Company and is participating in the Exchange Offer may be a statutory
underwriter and must comply with the registration and prospectus delivery
provisions of the Securities Act. Broker-dealers who acquired Original Notes
as a result of market making or other trading activities may use this
Prospectus, as supplemented or amended, in connection with resales of the
Exchange Notes. The Company has agreed that it will make this Prospectus
available to broker-dealers for use in connection with any such resale. Each
broker-dealer who receives Exchange Notes pursuant to the Exchange Offer must
acknowledge that it will deliver a current prospectus meeting the requirements
of the Securities Act in connection with any resale of such Exchange Notes.
The Letter of Transmittal that is filed as an exhibit to the Registration
Statement of which this Prospectus is a part (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. Any holder that cannot rely upon such
interpretations must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with a secondary resale
transaction.     
 
  The Original Notes and the Exchange Notes constitute new issues of
securities with no established public trading market. Any Original Notes not
tendered and accepted in the Exchange Offer will remain outstanding. To the
extent that Original Notes are tendered and accepted in the Exchange Offer, a
holder's ability to sell untendered, and tendered but unaccepted, Original
Notes could be adversely affected. Following consummation of the Exchange
Offer, the holders of Original Notes will continue to be subject to the
existing restrictions on transfer thereof and the Company will have no further
obligation to such holders to provide for the registration under the
Securities Act of the Original Notes except under certain limited
circumstances. (See "Note Registration Rights.") No assurance can be given as
to the liquidity of the trading market for either the Original Notes or the
Exchange Notes.
 
  This Prospectus and the Letter of Transmittal are first being mailed to
holders of Original Notes on      , 1998. The Exchange Offer is not
conditioned upon any minimum aggregate principal amount of Original Notes
being tendered or accepted for exchange. The Exchange Offer will expire at
5:00 p.m., New York City time, on      , 1998 unless extended (the "Expiration
Date"). The date of acceptance for exchange of the Original Notes (the
"Exchange Date") will be the first business day following the Expiration Date,
upon surrender of the Original Notes. Original Notes tendered pursuant to the
Exchange Offer may be withdrawn at any time prior to the Expiration Date;
otherwise such tenders are irrevocable.
 
  The Original Notes were issued originally in global form (the "Global
Original Notes"). The Global Original Notes were deposited with, or on behalf
of, The Depository Trust Company ("DTC"), as the initial depository with
respect to the Original Notes (in such capacity, the "Depositary"). The Global
Original Notes are registered in the name of Cede & Co. ("Cede"), as nominee
of DTC, and beneficial interests in the Global Original Notes are shown on,
and transfers thereof are effected only through, records maintained by the
Depositary and its participants. The use of the Global Original Notes to
represent certain of the Original Notes permits the Depositary's participants,
and anyone holding a beneficial interest in an Original Note registered in the
name of such a participant, to transfer interests in the Original Notes
electronically in accordance with the Depositary's established procedures
without the need to transfer a physical certificate. Exchange Notes issued in
exchange for the Global Original Notes will also be issued initially as a note
in global form (the "Global Exchange Notes," and, together with the Global
Original Notes, the "Global Notes") and deposited with, or on behalf of, the
Depositary. After the initial issuance of the Global Exchange Notes, Exchange
Notes in certificate form will be issued in exchange for a holder's
proportionate interest in the appropriate Global Exchange Note only as set
forth in the Indenture.

(the "WAM!NET(R) Service") that integrates the Company's industry-specific work
flow applications with commercially available computer and telephony
technologies. The Company, an affiliate of WorldCom Inc. ("WorldCom"), offers
an "Industry Smart(TM)" service designed to provide its subscribers with a
turn-key single source solution for the rapid, secure, accurate and reliable
transportation and management of information, with a simple "pay by the
megabyte" pricing plan requiring no capital investment. The WAM!NET Service
provides seamless digital connectivity among "communities of interest," drawing
together customers and trading partners which have collaborative work flows.
The Company has developed advanced WAM!NET Service applications, including an
on-line digital job tracking and billing system (Customer Information System or
"CIS"), an application enabling remote proofing ("WAM!PROOF(TM)") and a remote
data archiving, retrieval and distribution system ("WAM!BASE(TM)"). WAM!PROOF
was commercially released in the second quarter of 1998 and WAM!BASE is
scheduled for commercial release in the second half of 1998.
 
  The Company has initially capitalized on the growing need for managed digital
data delivery services in the printing, publishing, advertising, pre-press,
corporate communication and graphic arts industries (collectively, "Graphic
Arts"). The Company believes that the WAM!NET Service is achieving wide
acceptance among leading firms within the Graphic Arts community of interest,
which in turn encourages those with whom such firms share digital information
to subscribe to the WAM!NET Service. Since it commercially released and
commenced marketing of the WAM!NET Service in March 1996, the Company has
established a subscriber base of more than 1,500 customer locations, including
at Time Inc. ("Time"), R.R. Donnelley & Sons Company ("Donnelley"), The Walt
Disney Company ("Disney"), J.C. Penney Company, Inc. ("J.C. Penney"), Fox
Broadcasting Company ("Fox Broadcasting") and Macy's West (formerly known as
Macy's California) department stores ("Macy's"). In October 1997, the WAM!NET
Service received the Graphic Arts Technical Foundation (an independent trade
association) award for the product or service that will most likely change the
manner in which the Graphic Arts industry conducts business.
 
MARKET OPPORTUNITY
 
  The Company believes that the increasing digitalization of work product and
work flow in data intensive and time sensitive industries is driving demand for
managed, secure and reliable electronic data transportation and archiving
services. Based on information derived from independent studies, the Company
believes that the Graphic Arts industry will spend approximately $10.0 billion
between 1998 and 2000 on the digitalization of its production and printing
process, including the introduction by commercial printers of computer-to-plate
 
                                       1

("CTP") technology, which facilitates a fully digital work product. Despite
this movement toward the digital creation, storage and outputting of data, the
lack of reliable, cost effective electronic transport mechanisms has resulted
in many companies continuing to use overland or air courier services to deliver
magnetic tape or optical disk copies of data to others who desire access to
such data. This non-digital step results in a method of transporting data which
can be inefficient, significantly lengthening production cycle time and leading
to possible errors. The Company believes the potential market for managed
digital data transportation and asset storage services is $4.3 billion and $2.3
billion, respectively, in the Graphic Arts industry alone.
 
  The Company believes that existing electronic means for transporting large
digital data files have proven to be ineffective and/or prohibitively expensive
for most companies. Large files may take up to several days to transport using
the Internet or the fastest standard telephone modems (56,000 bps) and may lose
significant quality in transmission. The use of the Internet and standard
telephone modems can also lead to other significant disadvantages, most notably
high telephone usage charges and a lack of security, accountability and
reliability of transmission. Other non-dedicated technologies offer more speed
than the Internet or a standard telephone modem, but at a significantly higher
cost. Such technologies may also lead to data degradation and integration
obstacles. Large data files can be transported reliably in minutes over
dedicated point to point telephone lines (such as DS1 and DS3); however, the
substantial equipment necessary at each dedicated connecting point and the
sizable costs of leasing a dedicated point to point telephone line makes this
means of transport uneconomical for most companies transporting large data
files.
 
COMPETITIVE ADVANTAGES
 
  The Company believes it is uniquely positioned to meet the growing need for a
cost-effective and reliable means of electronically transporting, storing and
retrieving digital data due to the following competitive advantages:
 
 .  Purpose-Built, Industry Smart Network. The WAM!NET Service operates via a
   nationwide network that integrates the Company's proprietary, value-added
   Industry Smart applications with a purpose-built network of Company owned
   national, regional and local hubs ("Distribution Hubs") interconnected
   redundantly with high-bandwidth leased telephone circuits (the "WAM!NET
   Network"). The Company currently maintains 23 Distribution Hubs, located in
   major United States and Canadian cities, London, England and Paris, France.
   The Company operates two mirrored network operations centers ("NOCs") in
   Minneapolis and Las Vegas through which it monitors all data transmission on
   a 24 hour a day, 7 day a week basis. The Company believes the WAM!NET
   Service offers reliable and secure data transmissions with no degradation in
   quality and guaranteed delivery and throughput.
 
 .  Single Source, Turn-Key Service Solution. The Company provides each
   subscriber with all of the hardware, software, transmission facilities and
   management services necessary to use the WAM!NET Service. Installation of
   the service, which is performed on behalf of the Company by national service
   providers, consists of connecting the customer to the nearest Distribution
   Hub through a Company-owned network access device ("NAD") and an appropriate
   communications link (such as T1, ISDN, frame relay, ADSL or other suitable
   facility) matched to the customer's transfer speed and throughput
   requirements. The WAM!NET Service is designed for ease of use, with a point
   and click e-mail type interface and a simple "pay by the megabyte" pricing
   model. The Company's strategy is to offer customers the WAM!NET Service at
   rates competitive with overland and air courier services furnished on an
   annual or multi-year subscription basis. There is no up-front capital
   investment by the customer, who is charged based on a minimum monthly usage
   fee and volume of data sent per transaction.
 
 .  Industry Smart Applications. The Company collaborates with leading
   participants in its target markets and designs applications addressing
   industry-specific work product and work flow requirements. These Industry
   Smart applications combined with the guaranteed delivery and throughput of
   the WAM!NET Service allow work partners in distant geographic locations to
   collaborate digitally in real time. The WAM!PROOF
 
                                       2
<PAGE>
 
   application will allow customers to directly output across the WAM!NET
   Network to proofing devices in remote locations, thereby eliminating the
   need to deliver physical proofs by overnight courier. The WAM!BASE
   application will provide a collaborative digital asset management service
   that can eliminate the need for redundant archives and shrink work cycle
   time by providing more immediate access to desired data files.
 
 .  Customer Support and CIS. The Company has implemented extensive customer
   service functions, including customer support technicians who are available
   24 hours a day, 7 days a week, are trained extensively in the Company's
   service offerings and who understand the industry-specific work flow of the
   Company's customers. CIS allows customers to view data files, verify
   account information and check the status of transactions on-line, as well
   as to log help requests. The Company provides its customers itemized
   information regarding the size, cost, and destination of each "shipment"
   that may be electronically imported directly into the customer's own
   accounting system, which facilitates capturing of project-specific costs
   and billing of services on a job-by-job basis.
 
 .  First to Market Advantage. By being the first to market a managed, high
   speed digital data delivery network with Industry Smart applications, the
   Company believes it is becoming the industry standard in the Graphic Arts
   industry and is positioned to become the industry standard in its other
   target industries. The Company has found that industry leaders such as Time
   and Donnelley (early WAM!NET Service customers) actively encourage their
   work flow partners to subscribe to the WAM!NET Service to increase work
   flow efficiencies. Potential entrants into the managed digital data
   delivery field would need to deploy a nationwide, purpose-built network
   integrated with customized value-added applications, and simultaneously
   convert industry leaders and their work flow partners, more than 900 of
   whom have contracted with the Company for the WAM!NET Service at more than
   1,500 locations. Customers currently subscribing to the WAM!NET Service
   include 11 of the 20 largest publishers, 9 of the 20 largest printers, 16
   of the 20 largest advertising agencies, and 10 of the 20 largest pre-press-
   graphic arts agencies in the United States, as well as the corporate
   communications and advertising departments of many United States
   corporations.
 
 .  Strategic Relationship with WorldCom. The Company has entered into a
   strategic alliance with WorldCom which includes equity and debt investments
   and operating loan guarantees totaling approximately $50 million. WorldCom
   is currently entitled to designate a majority of the Board of Directors of
   the Company and, through its ownership of convertible debt and warrants,
   has the right to acquire a majority of the Common Stock of the Company.
   WorldCom also provides telecommunication and other services to the Company
   on a non-exclusive basis. The Company anticipates that its relationship
   with WorldCom will enable it to access the worldwide infrastructure, sales
   and marketing work force, telephony technologies, high bandwidth carrier
   service and other services of WorldCom and its affiliates, including UUNet
   Technologies, Inc. ("UUNet").
 
BUSINESS STRATEGY
 
  The Company's objective is to become the leading provider of enhanced,
managed digital data delivery and archiving services to industries comprised
of interdependent participants requiring industry specific, high speed digital
connectivity. WAM!NET's strategy to achieve this objective and to build a
long-term sustainable competitive advantage is to:
 
 .  Increase its Customer Base to Create Critical Mass. The Company's sales and
   marketing strategy has been designed to rapidly penetrate its initial
   target market, the Graphic Arts industry. Elements of this strategy
   include: (i) creating the WAM!NET Service as a turn-key, single source
   service solution; (ii) implementing an easy to understand "pay by the
   megabyte" pricing model (which eliminates the need for any capital
   investment by customers); (iii) designing aggressive advertising, trade
   show, event marketing and direct selling to drive trials, including
   introductory risk-free product evaluations for industry leaders; (iv)
   building a direct sales force to target leading industry participants who,
   in turn, encourage their work
 
                                       3
<PAGE>
 
   flow partners to subscribe to the WAM!NET Service; and (v) implementing
   programs in which large receivers of data (e.g., printers) promote and
   market the WAM!NET Service, along with the WAM!NET direct sales force, to
   customers and work flow partners. The Company believes that the customer
   benefits of the WAM!NET Service will increase exponentially as the total
   number of WAM!NET Service subscribers increases.
 
 .  Apply Industry Smart Network Model to Other Industries. The Company
   believes that the WAM!NET Industry Smart network model can provide the
   benefits and advantages it offers the Graphic Arts industry to other
   industries with similar data transportation, storage and retrieval
   requirements. Some of the Company's customers that are in the entertainment
   industry, such as Fox Broadcasting and Disney, currently subscribe to the
   WAM!NET Service for their Graphic Arts-related needs. The Company is
   presently developing Industry Smart applications suitable to the
   entertainment industry and is developing corresponding marketing and sales
   strategies. The Company is also collaborating with industry leaders in the
   medical imaging industry to develop and implement Industry Smart
   applications in connection with marketing to that industry.
 
 .  Drive Utilization Through Value-Added Services and Volume Discounts. The
   Company incorporates, develops and implements value-added Industry Smart
   applications for customers, such as CIS, WAM!PROOF and WAM!BASE, which the
   Company believes will provide significant benefits to its customers and
   stimulate increased usage of the WAM!NET Service. The Company also offers
   volume discounts and a variety of promotional programs for industry leaders
   to induce customers to send increasingly large volumes of data traffic
   across the WAM!NET Network.
   
 .  Expand and Enhance Infrastructure and Develop Worldwide Capabilities. The
   Company intends to invest in resources and systems to ensure that the
   WAM!NET Network's operating infrastructure and support services provide
   optimal digital connectivity to its subscribers in a guaranteed performance
   and competitive rate environment. The Company is currently preparing to
   expand into parts of Europe and Asia for the purpose of providing its
   customers with desired international connectivity. The Company expects to
   expand the WAM!NET Network into approximately 10 countries by the end of
   1998, and will initially locate additional Distribution Hubs in London,
   Frankfurt, Paris, Amsterdam, Milan, Tokyo, Hong Kong, and Sydney. The
   London and Paris Distribution Hubs were recently installed and the Company
   is currently in the process of installing a Distribution Hub in Amsterdam.
   During 1998, the Company expects to further develop its international
   service infrastructure by providing installation and customer support via
   third parties, developing local sales and distribution relationships and
   may establish additional Distribution Hubs and regional NOCs in selected
   countries. The Company's acquisition of 4-Sight Limited ("4-Sight") will
   permit subscribers, including 4-Sight's 30,000 customers in 44 countries,
   to gain remote access to the WAM!NET Network through transmission software
   being developed by 4-Sight. The Company may also establish its
   international presence through other acquisitions, joint ventures or other
   similar business transactions. See "--Recent Developments."     
 
 .  Reduce Costs and Improve Operating Margins. The Company seeks to reduce
   costs and improve operating margins by (i) spreading the cost of installing
   and operating the WAM!NET Network over a large base of customers; (ii)
   designing the network to use more expensive hub equipment in a few national
   and regional operational centers and less expensive equipment at each
   customer site; (iii) deploying cost-reduced NADs for less volume intense
   customers; (iv) pursuing programs to reduce the costs of capital equipment,
   including obtaining mass purchasing discounts for network infrastructure
   and customer premise equipment; (v) utilizing network management tools to
   optimize existing and planned network capacity as volume increases and
   traffic patterns begin to emerge; (vi) deploying new, lower-cost last mile
   local loop technologies to connect customer sites to Distribution Hubs,
   including wireless technologies and remote dial-up capabilities; and (vii)
   deriving other incremental revenue from value-added services such as
   WAM!BASE, which can be delivered over the existing WAM!NET Network
   infrastructure. The Company also believes its operating margins will
   improve as a result of anticipated cost reductions associated with
   increasing competition in both the local and long distance markets.

RECENT DEVELOPMENTS
 
  On March 13, 1998, the Company purchased the entire share capital of 4-Sight
Limited, a private limited company incorporated under the laws of England and
Wales (the "4-Sight Acquisition"), for $20.0 million in cash, which was paid
out of the proceeds of the Initial Offering, and 2,500,000 shares of Common
Stock which, subject to the satisfaction of certain conditions, may be
increased to 3,250,000 shares of Common Stock.
 
  4-Sight develops and distributes ISDN data transmission software and related
products and applications targeted to the Graphic Arts industry, with
particular emphasis on European, Asian and North American markets. 4-Sight
software users are generally responsible for all software and hardware
installation, procuring an ISDN telephony connection and verifying the
integrity of their files being sent over a public network infrastructure. The
Company believes that there are potential synergies in adapting and integrating
4-Sight's data transmission software into WAM!NET's managed network
infrastructure. At December 31, 1997, 4-Sight's customer base exceeded 30,000
locations, including 3,000 sites in the United States. The Company expects that
the 4-Sight Acquisition will enable the Company to achieve broader market
coverage in the Graphic Arts market by combining 4-Sight's international
presence and penetration of the lower volume user market with the Company's
domestic presence and penetration of the higher volume user market.
 
COMPANY HISTORY
   
  The Company was incorporated in Minnesota in September 1994. From
incorporation through March 1996, the Company was principally engaged in the
development of the WAM!NET Service. In March 1996, the Company commercially
released and began marketing the WAM!NET Service. Between September and
December 1996, the Company entered into its strategic alliance with WorldCom.
In 1997, the Company expanded its marketing efforts, increased its sales and
installation of the WAM!NET Service, continued development of WAM!PROOF and
WAM!BASE and other advanced applications, and prepared for expansion into
overseas markets and for the application of WAM!NET Services to other targeted
industries. WAM!PROOF was commercially released in the second quarter of 1998
and WAM!BASE is currently scheduled for commercial release in the second half
of 1998. In February 1998, the Company changed its name from NetCo
Communications Corporation to WAM!NET Inc. as part of a strategy to take
advantage of the market presence established by the Company's primary product,
the WAM!NET Service, and to avoid confusion between the more familiar product
name, "WAM!NET," and the less familiar corporate name, "NetCo."

                        Original Notes and the Indenture. To the extent that
                        Original Notes are tendered and accepted in the
                        Exchange Offer, the trading market, if any, for the
                        Original Notes could be adversely affected. See "Risk
                        Factors--Consequences of Failure to Exchange." The
                        Original Notes have been designated for trading in The
                        PORTAL Market ("PORTAL"), a subsidiary of The Nasdaq
                        Stock Market, Inc.  Original Notes that remain
                        outstanding following the consummation of the Exchange
                        Offer will continue to be designated for trading in
                        PORTAL.     
 
                                   THE NOTES
 
Notes.................  $208,530,000 aggregate principal amount at maturity of
                        13 1/4% Senior Discount Notes due 2005. The Original
                        Notes were issued on March 5, 1998 (the "Issue Date")
                        at a discount to their aggregate principal amount at
                        maturity and generated gross proceeds to the Company of
                        approximately $125.0 million. The yield to maturity of
                        the Notes is 14.59% (computed on a semi-annual bond
                        equivalent basis).
 
Maturity..............  March 1, 2005.
 
Interest..............  Cash interest does not accrue nor is payable on the
                        Notes prior to March 1, 2002. Thereafter, cash interest
                        on the Notes will accrue at a rate of 13 1/4% per annum
                        (calculated on a semi-annual bond equivalent basis) and
                        will be payable semi-annually in arrears on March 1 and
                        September 1 of each year, commencing September 1, 2002.
 
Ranking...............  The Notes are general senior obligations of the Company
                        and, as such, rank pari passu in right of payment with
                        all existing and future unsecured and
 
                                       7
<PAGE>
 
                        unsubordinated Indebtedness of the Company. The Notes
                        are effectively subordinated to all secured
                        Indebtedness of the Company to the extent of the value
                        of the assets securing such Indebtedness. As of March
                        31, 1998, the Company had outstanding approximately
                        $10.4 million of secured Indebtedness (consisting
                        principally of equipment financing), which effectively
                        ranked senior in right of payment to the Notes, no
                        Indebtedness which ranked pari passu in right of
                        payment to the Notes and $25.9 million of Indebtedness
                        which would have been subordinated in right of payment
                        to the Notes. Although the Indenture contains
                        limitations on the amount of additional Indebtedness
                        which the Company may incur, under certain
                        circumstances the amount of such Indebtedness could be
                        substantial, and the Indenture does not limit the
                        amount of secured Permitted Equipment Financing that
                        may be incurred by the Company. See "Description of the
                        Notes--Ranking."
 
Subsidiary                 
 Guarantees...........  The Indenture provides that each Material Restricted
                        Subsidiary (as defined herein) will become a guarantor
                        of the Notes (a "Subsidiary Guarantor"); provided,
                        however, that a Material Restricted Subsidiary that is
                        a Foreign Subsidiary shall not become a Subsidiary
                        Guarantor if by doing so it would violate applicable
                        law of its jurisdiction of organization or
                        incorporation. As of the date hereof, the Company has
                        no Material Restricted Subsidiaries that are Subsidiary
                        Guarantors. The guarantees of the Subsidiary Guarantors
                        (collectively, the "Subsidiary Guarantees"), if any,
                        will be general unsecured senior obligations of the
                        Subsidiary Guarantors and will rank pari passu in right
                        of payment with all unsecured and unsubordinated
                        Indebtedness of the Subsidiary Guarantors and senior in
                        right of payment to all subordinated Indebtedness of
                        the Subsidiary Guarantors. The Subsidiary Guarantees
                        may be released under certain circumstances. See
                        "Description of the Notes--Certain Covenants--Issuances
                        of Guarantees by Certain Restricted Subsidiaries;
                        Release of Guarantees." The Subsidiary Guarantees are
                        limited to the extent of any payment that would
                        constitute a fraudulent transfer under federal or state
                        law. See "Risk Factors--Fraudulent Conveyance
                        Considerations Relating to Subsidiary Guarantees."     
 
Optional Redemption...  The Notes are redeemable at the option of the Company,
                        in whole or in part, at any time upon not less than 30
                        nor more than 60 days written notice, on or after March
                        1, 2002, at the redemption prices set forth herein,

                        2001 (i) the Company may redeem up to 25% of the
                        originally issued aggregate principal amount at
                        maturity of Notes, other than in any circumstance
                        resulting in a Change of Control, at a redemption price
                        equal to 113.25% of the Accreted Value of the Notes so
                        redeemed as of the date of redemption, with the net
                        cash proceeds of an Initial Public Equity Offering
                        resulting in gross cash proceeds to the Company of at
                        least $35.0 million in the aggregate; provided that not
                        less than 75% of the originally-issued aggregate
                        principal amount at maturity of Notes is outstanding
                        immediately following such redemption. See "Description
                        of the Notes--Redemption--Optional Redemption."
 
Change of Control.....  In the event of a Change of Control, the Company is
                        required to make an offer to purchase all outstanding
                        Notes at a purchase price equal to 101% of the Accreted
                        Value thereof, plus accrued and unpaid interest
                        thereon, if any,

                        to the date of purchase. See "Description of the
                        Notes--Certain Covenants--Change of Control."
 
Asset Sale Offer......  The Company, subject to certain conditions, is
                        obligated to make an offer to purchase Notes with the
                        Net Cash Proceeds of certain Asset Sales at a purchase

                        Pursuant to the Registration Rights Agreement, the
                        Company agreed (i) to file a registration statement
                        (the "Exchange Offer Registration Statement") with
                        respect to an offer to exchange the Original Notes (the

                        payments to holders of Notes under certain
                        circumstances if the Company is not in compliance with
                        its obligations under the Registration Rights

                SUMMARY HISTORICAL AND PRO FORMA FINANCIAL DATA
 
  The following tables set forth (i) selected historical consolidated financial
data for the Company and its subsidiaries for each of the years in the three
year period ended December 31, 1997, and for the three month periods ended
March 31, 1997 and 1998, (ii) selected historical consolidated financial data
for 4-Sight and its subsidiaries for the year ended August 31, 1996, the month
ended September 30, 1996, the year ended September 30, 1997 and the twelve
months ended December 31, 1997 and (iii) selected pro forma financial data that
gives effect to the Offering and the 4-Sight Acquisition as if they had
occurred on January 1, 1997. The 4-Sight Acquisition occurred on March 13, 1998
and the operating results of 4-Sight are included in the Company's operating
results from that date through March 31, 1998. The Company's summary historical
consolidated financial data as of and for the three months ended March 31, 1997
and 1998 and 4-Sight's selected historical consolidated financial data as of
and for the twelve months ended December 31, 1997 have been derived from the
respective companies' unaudited financial statements and have been prepared on
the same basis as the historical information derived from audited financial
statements. In the opinion of the management of the Company and the management
of 4-Sight, the unaudited financial statements of the respective companies,
from which such data have been derived, contain all adjustments, consisting
only of normal recurring accruals, necessary for the fair presentation of the
results for and as of the end of such periods. The Company's development and
expansion activities during the periods presented below significantly affect
the period-to-period comparability of the historical data presented for the
Company. The historical data with respect to the three months ended March 31,
1998 should not be regarded as necessarily indicative of the results that may
be expected for the entire year. The following information is qualified in its
entirety by, and should be read in conjunction with, the consolidated financial
statements and the notes thereto of the Company and 4-Sight, "Pro Forma
Financial Data" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations" included elsewhere herein.

- --------
   
(1) EBITDA represents earnings (loss) from operations before taking into
    consideration net interest expense, income tax expense, depreciation
    expense and amortization expense. The Company has included information
    concerning EBITDA as it is used by certain investors as a measure of a
    company's ability to service its debt. EBITDA should not be considered as
    an alternative to net income or any other measure of performance or
    liquidity as determined in accordance with generally accepted accounting
    principles or as an indicator of the Company's overall financial
    performance. In addition, the measure of EBITDA presented herein by the
    Company may not be comparable to other similarly titled measures of other
    companies.     
   
(2) The ratio of earnings to fixed charges is calculated by dividing (i) net
    income (loss) before taxes plus fixed charges by (ii) fixed charges. Fixed
    charges consist of interest incurred and the portion of rent expense which
    is deemed representative of interest. Earnings were insufficient to cover
    fixed charges by $1,242, $6,653 and $29,180 for the Company for the years
    ended December 31, 1995, 1996 and 1997, and $3,907 and $23,184 for the
    three month period ending March 31, 1997 and 1998, and $33,433 for the pro
    forma financial data for the year ended December 31, 1997 and $32,448 for
    the pro forma financial data for the three month period ended March 31,
    1998, respectively. Earnings were insufficient to cover fixed charges by
    $0.04 for 4-Sight for the one month period ended September 30, 1996.     
(3) Total debt includes long-term debt, current portion of long-term debt and
    obligations under capitalized leases, net of the unamortized value of
    warrants issued to debtholders.
(4) The estimated value of warrants issued to debtholders and of options issued
    to consultants is reflected as both a debt discount and an element of paid
    in capital.
(5) 4-Sight changed its fiscal year end to September 30 during 1997.
(6) 4-Sight's fiscal year ends on September 30. The financial data of 4-Sight
    for the twelve months ended December 31, 1997 is presented for comparative
    purposes and in connection with the pro forma data.
(7) The pro forma financial data is not necessarily indicative of either future
    results of operations or the results that might have occurred if the
    foregoing transactions had been consummated on the indicated dates.

                                 RISK FACTORS
   
  Prospective participants in the Exchange Offer should carefully consider the
following risk factors, as well as other information contained in this
Prospectus, before participating in the Exchange Offer.     
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
  Holders of Original Notes who do not exchange their Original Notes for
Exchange Notes pursuant to the Exchange Offer will continue to be subject to
the restrictions on transfer of such Original Notes as set forth in the legend
thereon as a consequence of the issuance of the Original Notes 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. Except under certain limited circumstances, the Company
does not intend to register the Original Notes under the Securities Act. 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 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. To the extent
Original Notes are tendered and accepted in the Exchange Offer, the trading
market, if any, for the Original Notes not tendered could be adversely
affected. See "Note Registration Rights."
 
LIMITED OPERATING HISTORY; HISTORY OF LOSSES; NO ASSURANCE OF PROFITABILITY
   
  The Company was formed in September 1994 and has a limited history of
operations. It began operations in March 1995 and has operated at a net loss
since inception. The Company expects to incur substantial losses for the
foreseeable future as it continues to expand the WAM!NET Network, develop
other products and applications and improve and market its services. The
Company incurs significant sales commissions and installation costs as
customers initially subscribe to the WAM!NET Service. As part of its sales and
marketing efforts, the Company offers certain customers, including potentially
influential industry leaders, free service for an initial evaluation period.
Accordingly, management expects that operating costs will remain high as a
percentage of revenue as the Company seeks to continue its rapid growth in
subscribers. Since the Company's inception on September 9, 1994, the Company
has incurred operating losses of $61.0 million and as of March 31, 1998 had a
shareholders' deficit of $15.3 million. Due to the Company's negative cash
flow and need to obtain additional financing to carry out its business plan,
prior to the consummation of the Initial Offering, the report of the Company's
independent auditors included an explanatory paragraph with respect to the
ability of the Company to continue as a going concern. However, the Company's
independent auditors reissued their opinion on the Company's 1997 consolidated
financial statements without such paragraph upon the consummation of the
Initial Offering. The likelihood of the Company achieving profitability must
be considered in light of the problems frequently encountered by a new
business and the competitive environment in which the Company operates. To
keep the price of the WAM!NET Service competitive, the Company must enter into
service contracts with and retain additional customers which will enable the
Company to increasingly spread the fixed costs of the WAM!NET Service over
many customers. There can be no assurance that the Company will develop an
adequate revenue generating customer base or will achieve or sustain
profitability or generate sufficient positive operating cash flow to service
its debt. See "--Requirements for Additional Capital," "--Competition;
Technological Change," "Management's Discussion and Analysis of Financial
Condition and Results of Operations," and the Company's consolidated financial
statements, including the notes thereto, included elsewhere herein.     
 
REQUIREMENTS FOR ADDITIONAL CAPITAL
   
  The Company's ability to meet its projected growth is dependent upon its
ability to secure substantial additional financing in the future. The Company
expects to meet its additional capital needs with the proceeds from sales or
issuance of equity securities, credit facilities and other borrowings, or
additional debt securities, each to the extent permissible under the
Indenture. In addition, although the Indenture permits the Company to     
 
                                      12
<PAGE>
 
   
incur additional indebtedness under certain conditions, including an unlimited
amount of secured equipment financing, the Indenture could serve to restrict
the financing options available to the Company to fulfill its expansion plans.
See "Description of the Notes--Certain Covenants." The Company also intends to
pursue one or more financings in 1998 totalling approximately $100.0 million,
for which it has received indications of interest from certain financial
institutions. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Liquidity and Capital Resources." The Company
believes that the net proceeds of the Initial Offering and such financings,
together with expected cash from operations, will be sufficient to fund the
Company's operations through September 30, 1999 (through March 31, 1999
without such financing). There can be no assurance that the Company will be
able to obtain such financing if and when it is needed or that, if available,
such financing will be on terms acceptable to the Company. Further, there can
be no assurance that expenses will not exceed the Company's estimates or that
the financing need will not likewise be higher. If the Company is unable to
obtain additional financing when needed, it may be required to significantly
scale back expansion plans and, depending upon cash flow from its existing
business, reduce the scope of its plans and operations. Any additional debt
financing, if available, may involve restrictive covenants that attempt to
address interests different than those of the holders of the Notes. Further,
there can be no assurance that such covenants will not adversely affect the
Company's ability to finance its future operations or capital needs or to
engage in other business activities that may be in the interest of the
Company. The Company's financing needs may vary significantly from its current
expectations if it is unable to generate anticipated cash flows or if the
Company requires more funds for equipment investments than it currently
anticipates, particularly as a result of future network infrastructure
installation requirements. No assurance can be given that the Company's
current expectations regarding its cash needs will prove accurate, and there
can be no assurance that the Company's operations will produce positive cash
flow in sufficient amounts to service the Notes. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."     
 
LEVERAGE AND DEBT SERVICE
 
  The Company is highly leveraged. As of March 31, 1998, the Company had
approximately $161.5 million of Indebtedness. As a result of the substantial
indebtedness of the Company following the Initial Offering, fixed charges are
expected to exceed its operating cash flow for the foreseeable future and
there can be no assurance that the Company's operating cash flow will be
sufficient to pay cash debt service on the Notes when cash interest begins to
accrue on the Notes commencing 2002. In addition, the Indenture permits the
Company to incur additional indebtedness under certain conditions, including
an unlimited amount of secured equipment financing. The leveraged nature of
the Company could limit the ability of the Company to effect future financings
or may otherwise restrict the Company's activities. Substantial leverage poses
the risk that the Company may not be able to generate sufficient cash flow to
service its indebtedness, including the Notes, and to adequately fund its
operations. See "Description of the Notes--Ranking."
 
  The degree to which the Company is leveraged could have important
consequences to the holders of the Notes, including the following: (i) the
Company's ability to obtain additional financing for working capital, capital
expenditures, acquisitions, general corporate purposes or other purposes may
be impaired in the future; (ii) a substantial portion of the Company's cash
flow from operations must be dedicated to the payment of debt service, thereby
reducing the funds available to the Company for other purposes; (iii) the
Company's leverage may hinder its ability to adjust rapidly to changing market
conditions; and (iv) the Company's leverage could make the Company more
vulnerable in the event of a downturn in general economic conditions or in its
business.
 
RISKS ASSOCIATED WITH A CHANGE OF CONTROL
 
  The Indenture contains provisions relating to certain events constituting a
"change of control" of the Company. Upon the occurrence of such a change of
control, the Company would be obligated to make an offer to purchase all of
the Notes then outstanding at a purchase price equal to 101% of the principal
amount thereof, plus accrued and unpaid interest to the date of purchase.
There can be no assurance that the Company would have sufficient funds, or be
able to obtain such funds on commercially reasonable terms, to purchase all of
the
 
                                      13
<PAGE>
 
   
Notes tendered pursuant to such an offer. A failure by the Company to purchase
all Notes validly tendered pursuant to such an offer would result in an Event
of Default under the Notes and could result in an event of default under other
indebtedness of the Company. In addition, a change of control could result in
the acceleration of existing or future indebtedness of the Company that is
senior to the Notes, and, as such, may adversely affect the ability of the
Company to repay the Notes. See "Description of the Notes--Certain Covenants--
Change of Control."     
 
RISK OF NETWORK FAILURE; LIABILITY FOR DATA
 
  The Company's operations are dependent upon its ability to protect its
network infrastructure against damage from natural disasters, power loss,
telecommunications failures and similar events. Despite the current redundancy
of the WAM!NET Service's infrastructure (other than from a customer's NAD to a
Distribution Hub), and other precautions taken by the Company, the occurrence
of a natural disaster or other unanticipated problem could cause interruptions
to the WAM!NET Service. Additionally, failure of the Company's
telecommunications providers to provide the telephony capacity required by the
Company as a result of operational disruption or for any other reason could
cause interruptions in the services provided by the Company.
 
  The WAM!NET Service uses an assemblage of telecommunications equipment,
software, operating protocols and proprietary applications for high speed
transportation of large quantities of digital data among multiple locations.
Given the complexity of the WAM!NET Service, it is possible that data files
may be lost or distorted. Moreover, most of the Company's customers' needs are
extremely time sensitive, and delays in data delivery may cause significant
losses to a customer using the WAM!NET Service. The WAM!NET Service and future
enhancements or adaptations may contain undetected design faults and software
"bugs" that, despite testing by the Company, are discovered only after the
WAM!NET Service has been installed and used by customers. The failure of any
equipment or facility on the WAM!NET Network could result in the interruption
of service to the customers serviced by such equipment or facility until
necessary repairs are effected or replacement equipment is installed. Such
failures, faults or errors could cause delays or require modifications that
could have a material adverse effect on the Company's business, financial
condition, competitive position and results of operations.
   
  Although the Company's contracts with most WAM!NET Service subscribers limit
the Company's liability for damages resulting from any failure in the
transportation of data to $100 per transmission, with a maximum liability
equal to the subscriber's monthly maximum subscription rate, the Company may
nevertheless be subject to significant claims for data losses or delays in the
transportation of data over the WAM!NET Network. In addition to general
business liability coverage, the Company presently maintains errors and
omissions insurance coverage in the amount of $1.0 million per occurrence and
$5.0 million for all occurrences relating to the transportation of data over
the WAM!NET Network.  In addition, the Company presently maintains $1.0
million of business interruption insurance coverage against losses from
floods, earthquakes and other natural disasters. There can be no assurance
that this amount of insurance coverage will be adequate to cover all data loss
claims, or that additional coverage will be available on affordable terms to
the Company. See "Business--Liability and Insurance."     
 
SECURITY RISKS
 
  Despite the WAM!NET Service's extensive security measures, including audit
software that constantly monitors security breaches or tampering, the WAM!NET
Service is vulnerable to unauthorized access, computer viruses and other
disruptive problems. Eliminating computer viruses and alleviating other
security problems may require interruptions, delays or cessation of service to
the Company's customers which could have a material adverse effect on the
Company's business, financial condition, competitive position and results of
operations.
 
DEPENDENCE UPON NETWORK INFRASTRUCTURE AND AVAILABLE BANDWIDTH
 
  The Company's ability to generate positive cash flows from operations will
depend upon its ability to increase its existing subscriber base, which is a
function, in part, of its ability to expand its national network
 
                                      14
<PAGE>
 
infrastructure and support services in order to supply enhanced capacity,
reliability and security to subscribers at an acceptable cost. The continued
development and expansion of the Company's national network will require that
it enter into additional agreements, on acceptable terms and conditions, with
various providers of infrastructure capacity and equipment and support
services. No assurance can be given that any or all of the requisite
agreements can be obtained on satisfactory terms and conditions.
 
  The Company anticipates that future expansions and adaptation of its network
infrastructure may be necessary in order to respond to growth in the number of
customers served, increased demands to transmit larger amounts of data and
changes to its customers' service requirements as customers become more
familiar and comfortable with the WAM!NET Service and its various
applications. The expansion and adaptation of the Company's network
infrastructure will require substantial financial, operational and managerial
resources. There can be no assurance that the Company will be able to expand
or adapt its network infrastructure to meet the evolving standards or demands
of its targeted industries and customers and changing requirements on a timely
basis, at a commercially reasonable cost, if at all, or that the Company will
be able to deploy successfully any expanded and adapted network
infrastructure.
 
REGULATORY MATTERS
 
  North America. The Company purchases telephone equipment, routers and relays
that are used in the WAM!NET Network from manufacturers and combines that
equipment with Company provided software and telephone circuits provided by
common carriers regulated by the Federal Communications Commission ("FCC"),
the Canadian Radio-Television and Telecommunications Commission ("CRTC") and
various state regulatory agencies. The Company believes that under the FCC's
interpretation of the Communications Act of 1934, as amended, the services
which it offers to its customers are interstate information (enhanced)
services. Consequently, it is not required to obtain licenses or other
approvals from the FCC or state regulatory agencies to offer such services. If
the Company's services were deemed to be intrastate services, certain state
regulatory agencies might seek to assert jurisdiction over the Company's
offerings. If that were to occur, the Company could be required to expend
substantial time and money to acquire the appropriate licenses and to comply
with state regulations. The Company also believes that under the CRTC's
interpretation of Canadian law, the services that the Company offers do not
require it to obtain telecommunications permits or approvals in Canada.
 
  Worldwide. The Company believes that European Union directives require that
member states permit the provision of the Company's services on a competitive
basis. Bilateral agreements have been negotiated between the United States and
Japan and the United States and Hong Kong which encourage cross-border
provision of enhanced services like those offered by the Company. Pursuant to
commitments in the World Trade Organization's ("WTO") General Agreement on
Trade in Services, over 50 governments have agreed to permit provision of
enhanced services (i.e., value-added) by nationals of WTO member countries.
Nevertheless, certain other countries in Europe, Asia and elsewhere might seek
to license and regulate the Company's services. Any such license or regulation
may limit, delay or increase the costs of operations associated with
international locations to which the Company may desire to expand.
          
  Medical Imaging. The Company intends to offer its WAM!NET Service and
WAM!BASE service as medical imaging applications for transmitting, storing and
retrieving medical data for primary diagnostic purposes. The Company is
currently participating in a test of the medical image transmission
application of the WAM!NET Service between a hospital and a remotely located
clinic, and intends to commence testing of the WAM!BASE storage and retrieval
functions during the fourth quarter of 1998. Any medical imaging applications
offered for primary diagnostic purposes are required to comply with the Food,
Drug and Cosmetic Act, as amended (the "Food and Drug Act"), and regulations
promulgated thereunder by the Food and Drug Administration (the "FDA"). Under
recently adopted FDA regulations, both the WAM!NET Service's data transmission
application and the WAM!BASE data storage and retrieval application are
classified as Class I devices that do not perform "irreversible data
compression." Prior to adoption of those regulations, both the transmission
and storage functions were classified as Class II devices, and the Company had
received marketing

clearance from the FDA for data transmission pursuant to a 510(k) Premarket
Notification filing. The Company's medical image transmission, storage and
retrieval applications conform to the Digital Imaging and Communications in
Medicine ("DICOM") industry standards, which are the industry accepted
standards utilized by major medical imaging equipment manufacturers in the
domestic health care industry. The Company works with medical imaging
equipment manufacturers to ensure compatibility of the WAM!NET Service and
WAM!BASE applications with their medical imaging equipment. See "Business--
Government Regulation, Standards."     
 
DEPENDENCE ON MANAGEMENT
 
  The Company is dependent primarily on the services of Edward J. Driscoll
III, its Chief Executive Officer, and is also dependent on the services of
certain of its other officers and significant employees. The loss of the
services of any of these persons could have a material adverse effect on the
Company. The Company has employment agreements with substantially all of its
officers and significant employees, including Mr. Driscoll, and has purchased
life insurance policies on certain employees, including Mr. Driscoll. See
"Management." The Company believes its future success will depend in large
part on its ability to retain the services of these personnel and to attract
and retain qualified technical and marketing personnel. There can be no
assurance that the Company will be able to continue to attract and retain the
personnel necessary for the successful conduct of its business.
 
RAPID EXPANSION; MANAGEMENT OF GROWTH
 
  The Company rapidly expanded its distribution network and added subscribers
to the WAM!NET Service during fiscal 1997, and must continue to aggressively
expand its network and add subscribers in order to achieve its business
objectives. During 1998, the Company intends to expand the WAM!NET Service
into international markets. Whether the Company can meet its goal of
increasing its customer base while maintaining its price structure and
managing costs will depend upon, among other things, the Company's ability to
manage its growth effectively. To manage growth effectively, the Company must
continue to develop its sales force, external installation capability,
customer service teams and information systems, and must maintain its
relationships with third-party vendors. The Company's management will also be
required to assume greater levels of responsibility. If the Company is unable
to manage its growth effectively, the Company's business and results of
operations could be materially adversely affected.
 
  The 4-Sight Acquisition will require the management of the Company and 4-
Sight to spend substantial time integrating the network operations of the
Company with the software transmission and services business of 4-Sight. 4-
Sight's transmission software and services are sold primarily to customers
with lower bandwidth and throughput requirements than that needed by most
current subscribers to the WAM!NET Service. Also, the use of 4-Sight's current
products requires the use of ISDN lines.
 
DEPENDENCE ON THIRD-PARTY SUPPLIERS FOR EQUIPMENT AND SERVICES
 
  The Company is dependent on its third-party local and long distance carriers
and on third-party suppliers of the computers, software, routers and related
components that the Company assembles and integrates into the WAM!NET Service.
Most of these supplier arrangements are for terms of less than one year and
are terminable by the other party in certain circumstances. The Company is
also dependent on the services of third parties with whom it has contracted or
may contract in the future for customer site installations, routine
maintenance and on-call repair services. While the Company believes that its
relationships with these vendors and suppliers are satisfactory, and that
suitable alternative products and services are available, the Company may
experience delays and additional costs if any of these relationships is
terminated and the Company is unable to reach suitable agreements with
alternate vendors, suppliers or carriers in a timely manner. Furthermore, to
the extent that the Company is unable to secure suitable installation,
maintenance or on call repair services from third-party vendors, the Company
may be required to substantially increase its own work force to perform these
services, and the Company's growth may be constrained while it builds and
trains that work force. See "Business--Supplier Relationships."
 
                                      16
<PAGE>
 
  The Company has historically experienced a 60 to 90 day delay in obtaining
telephone line extensions at subscriber premises following the execution of a
WAM!NET Service contract. There can be no assurance that the Company will be
able to obtain such telephone lines on the scale and within the time frames
required by the Company at a commercially reasonable cost, or at all.
 
AFFILIATION OF WORLDCOM
 
  Through its ownership of debt and equity securities of the Company, as well
as its designation of a majority of the directors of the Board of Directors of
the Company, WorldCom has the ability to exercise considerable influence and
control over the affairs of the Company. Other than as required under
Minnesota law, no formal policies or guidelines have been adopted by the Board
of Directors of the Company to deal with Board actions that may involve actual
or potential conflicts of interest between the Company and WorldCom. No
assurance can be given that any conflict of interest that may arise will not
be resolved in a manner adverse to the holders of Notes. In addition, WorldCom
and its affiliates are non-exclusive suppliers of telecommunication and other
services to the Company. The Company has no contractual right to obtain
technological assistance from WorldCom. WorldCom has no obligation to
contribute funds to the Company (except with respect to its obligations in
connection with the Company's contractual relationship with Time and under the
Company's revolving credit facility (the "Revolving Credit Facility"), which
obligations are described herein under "Certain Transactions and
Relationships"), maintain its equity interest in the Company or support any
obligation of the Company with respect to the Notes. Further, a loss of its
strategic relationship with WorldCom could have a materially adverse effect on
the business and operations of the Company and on the market for the Notes.
See "Certain Transactions and Relationships."
 
COMPETITION; TECHNOLOGICAL CHANGE
 
  The Company operates in a highly competitive industry which includes many
companies that have greater resources and market presence than the Company.
The Company's potential competitors have invested and continue to invest
substantial sums in research and development which may result in products and
services that have a competitive advantage over the WAM!NET Service. A new
service called the Graphic Arts Digital Network, which will be a direct
competitor of the WAM!NET Service, has been announced but not yet released. As
announced, the service will be provided by a joint venture between British
Telecommunications and Scytek Inc. ("Scytek"). There are relatively few
barriers to entry into the marketplace for the high speed delivery of digital
data files, and additional competitors could enter the market at any time. The
Company is also at risk from fundamental technological changes in the way
connectivity solutions are marketed and delivered. As is typical in the case
of a new and evolving industry characterized by rapidly changing technology,
evolving industry standards and new product and service introductions, demand
and market acceptance for recently introduced products and services are
subject to uncertainty of customer acceptance. There can be no assurance that
the Company will be able to adapt to future technological changes or that
developments by competitors will not render the WAM!NET Service and related
services obsolete or noncompetitive. See "Business--Competition" and "--
Intellectual Property and Proprietary Rights."
 
INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS
 
  The Company's success may depend, in part, on its ability to maintain its
proprietary rights in certain technology underlying the WAM!NET Service and
related applications. The Company has applications for three United States
patents pending for certain aspects of its technology. To protect its
proprietary rights in the technology utilized in the WAM!NET Service, the
Company relies on a combination of trade secret and copyright protection as
well as patents. The Company also relies on trademark protection concerning
various names, marks, logos and other devices which serve to identify the
Company as the source for and originator of the WAM!NET Service and related
applications. The Company may choose not to apply for patent protection in all
foreign countries in which it eventually markets the WAM!NET Service.
Consequently, the Company's proprietary rights in the technology underlying
the WAM!NET Service and related applications will be protected only to the
extent that trade secret, copyright or other non-patent protection is
available in such countries and to the extent the Company is able to enforce
such rights.
 
                                      17
<PAGE>
 
   
  Given the recent acquisition of 4-Sight, with its substantial international
presence, the Company will increasingly offer its products and services in
foreign countries. However, some of these countries may lack intellectual
property protection that is comparable to that afforded by the intellectual
property laws of the United States. There can be no assurance that the steps
taken by the Company to protect its intellectual property and proprietary
rights will be adequate to deter misappropriation of its technology or
independent development by others of technologies that are substantially
equivalent or superior to the Company's technology. Any such misappropriation
of the Company's technology or development of competitive technologies could
have a material adverse effect on the Company's business, operating results
and financial conditions. The Company could incur substantial expense in
protecting and enforcing its intellectual property rights in foreign
countries.     
 
  Intellectual property litigation is complex and there can be no assurance of
the outcome of any such litigation. Any future litigation, regardless of
outcome, could result in substantial expense to the Company and significant
diversion of the efforts of the Company's technical and management personnel.
An adverse determination in any such proceeding could subject the Company to
significant liabilities to third parties, require disputed rights to be
licensed from such parties, if licenses to such rights could be obtained,
and/or require the Company to cease using such technology. There can be no
assurance that any such license would or could be obtained at costs reasonable
to the Company. If forced to cease using such technology, there can be no
assurance that the Company would be able to develop or obtain alternate
technology. Accordingly, an adverse determination in a judicial or
administrative proceeding or failure to obtain necessary licenses could
prevent the Company from manufacturing, using or selling certain of its
products, which could have a material adverse effect on the Company's
financial condition and business results of operations. See "Business--
Intellectual Property and Proprietary Rights."
 
DEPENDENCE UPON SIGNIFICANT CUSTOMERS
 
  During fiscal 1997, Time and WorldColor Press Inc. ("WorldColor") were the
Company's largest customers, representing 10.9% and 9.6%, respectively, of the
Company's total net sales. In the event Time or WorldColor significantly
reduced, for any reason, or terminated (at the end of its current service
contract or otherwise), its use of the WAM!NET Service, the Company's
financial condition and business results of operations could be materially
adversely affected, both as a direct result of such reduction or termination
and through the potential reduction of use of the WAM!NET Service by Time or
WorldColor's work flow partners that are, or potentially would be, subscribers
to the WAM!NET Service.
 
DISCRETIONARY AUTHORITY OVER USE OF NET PROCEEDS
 
  The Company retains a significant amount of discretion over the application
of the net proceeds of the Initial Offering. Because of the number and
variability of factors that determine the Company's use of the net proceeds of
the Initial Offering, there can be no assurance that such applications will
not vary substantially from the Company's current intentions. Pending such
utilization, the Company invests the net proceeds of the Offering in short-
term investment grade and government securities. See "Use of Proceeds."
 
ABSENCE OF PUBLIC MARKET; RESTRICTION ON RESALE
 
  The Exchange Notes are a new issue of securities for which there is
currently no established market. There can be no assurance as to (i) the
liquidity of any such market that may develop, (ii) the ability of the holders
of Exchange Notes to sell any of their Exchange Notes, or (iii) the price at
which the holders of Exchange Notes would be able to sell any of their
Securities. The Company does not presently intend to apply for listing of any
of the Exchange Notes on any national securities exchange or on The Nasdaq
Stock Market. The Initial Purchasers have advised the Company that they
presently intend to make a market in Exchange Notes, if and when issued. The
Initial Purchasers are not obligated, however, to make a market in the
Exchange Notes and any such market-making may be discontinued at any time at
the sole discretion of the Initial Purchasers and without notice. Accordingly,
no assurance can be given as to the development or liquidity of any market for
any
 
                                      18
<PAGE>
 
of the Exchange Notes. If a market for any of the Exchange Notes were to
develop, such Exchange Notes could trade at prices that may be higher or lower
than reflected by their initial offering price depending on many factors,
including prevailing interest rates, the Company's operating results and
prospects for its performance, the market for similar securities and general
economic conditions. Historically, the market for securities such as the Notes
has been subject to disruptions that have caused substantial volatility in the
prices of similar securities. There can be no assurance that if a market for
any of the Notes were to develop, such a market would not be subject to
similar disruptions.
 
FRAUDULENT CONVEYANCE CONSIDERATIONS RELATING TO SUBSIDIARY GUARANTEES
   
  The Company's obligations under the Notes will be guaranteed on an unsecured
senior basis by the Subsidiary Guarantors, if any. Various fraudulent
conveyance laws have been enacted for the protection of creditors and may be
utilized by a court of competent jurisdiction to subordinate or avoid any
Subsidiary Guarantee issued by a Subsidiary Guarantor. It is also possible
that under certain circumstances a court could hold that the direct
obligations of a Subsidiary Guarantor could be superior to the obligations
under its Subsidiary Guarantee. There are currently no Subsidiary Guarantors.
    
  To the extent that a court were to find that (x) a Subsidiary Guarantee was
incurred by a Subsidiary Guarantor with the intent to hinder, delay or defraud
any present or future creditor or that the Subsidiary Guarantor contemplated
insolvency with a design to favor one or more creditors to the exclusion in
whole or in part of others or (y) a Subsidiary Guarantor did not receive fair
consideration or reasonably equivalent value for issuing a Subsidiary
Guarantee and, at the time it issued such Subsidiary Guarantee, the Subsidiary
Guarantor (i) was insolvent or rendered insolvent by reason of the issuance of
the Subsidiary Guarantee, (ii) was engaged or about to engage in a business or
transaction for which the remaining assets of such Subsidiary Guarantor
constituted unreasonably small capital or (iii) intended to incur, or believed
that it would incur, debts beyond its ability to pay such debts as they
matured, the court could avoid or subordinate such Subsidiary Guarantee in
favor of the Subsidiary Guarantor's other creditors. Among other things, a
legal challenge of a Subsidiary Guarantee issued by a Subsidiary Guarantor on
fraudulent conveyance grounds may focus on the benefits, if any, realized by
such Subsidiary Guarantor as a result of the issuance by the Company of the
Notes. To the extent any Subsidiary Guarantee is avoided as a fraudulent
conveyance or held unenforceable for any other reason, the holders of the
Notes would cease to have any claim in respect of the applicable Subsidiary
Guarantor and would be creditors solely of the Company.
 
RISKS OF FOREIGN INVESTMENT
   
  Primarily through the acquisition of 4-Sight, the Company has expanded its
operations into Europe, and, to a lesser extent, Asia, in the first half of
1998. Risks inherent in foreign operations include loss of revenue, property
and equipment from expropriation, nationalization and confiscatory taxation.
The Company is also exposed to the risk of changes to laws and policies that
govern foreign investment in countries where it has operations as well as, to
a lesser extent, changes in United States laws and regulations relating to
investing in or trading with countries in which the Company may have
investments.     
 
  Certain of the countries in which the Company operates or may operate may be
subject to a substantially greater degree of social, political and economic
instability than is the case in other countries. Such instability may result
from, among other things, the following: (i) authoritarian governments or
military involvement in political and economic decision making, and changes in
government through coups or other extra-constitutional means; (ii) social
unrest associated with demands for improved economic, social and political
conditions; (iii) internal insurgencies and terrorist activities; and (iv)
hostile relations with neighboring countries. Risks associated with social,
political and economic instability in a particular country could materially
adversely affect the results of operations and financial condition of the
Company and could result in the loss of the Company's assets in such country.
 
                                      19
<PAGE>
 
   
  During 1997 the Company, on a pro forma basis after giving effect to the 4-
Sight Acquisition, received less than 5% of its total revenue from sales and
operations in Asian countries. As a result, the Company had limited exposure
to the particular risks attendant to doing business in Asia and did not
experience any material adverse effects from the Asian economic crisis;
however, the Company presently intends to expand its operations in that
region. The Company is currently unable to determine the effect, if any, that
recent economic downturns in Asia, particularly Japan, will have on the
Company's future business, operating results or liquidity, although the
Company intends to exercise prudence and sound business judgment prior to
making any future investments in Asia.     
 
FOREIGN CURRENCY EXCHANGE RATES; REPATRIATION
   
  As the Company expands its operations into countries outside of the United
States, its results of operations and the value of its assets will be affected
by the currency exchange rates between the U.S. dollar and the functional
currency of countries in which it has assets. The Company may also sell
products and services in certain countries in the local functional currency or
in a currency other than the U.S. dollar. As a result, the Company may
experience an economic loss solely as a result of foreign currency exchange
rate fluctuations, which include foreign currency devaluations against the
dollar. The Company may in the future acquire interests in companies that
operate in countries where the removal or conversion of currency is
restricted. There can also be no assurance that countries that do not have
such restrictions at the time the Company establishes operations in those
countries will not subsequently impose them, especially in situations where
there is a deterioration in a country's balance of payments or where the local
currency is being heavily converted into other currencies. Currently, the
Company does not employ currency hedging strategies to reduce the risks
associated with the fluctuation of foreign currency exchange rates. The
Company presently denominates all of its contracts in U.S. dollars. 4-Sight
denominates all of its contracts in pounds sterling except for its U.S. sales,
which are denominated in U.S. dollars, and its German sales, which are
denominated in German marks. In addition, the Company is unable to determine
what effect, if any, the adoption and use of the euro, the single European
currency to be introduced in January of 1999, will have on the Company's
business, operating results, liquidity and financial condition.     
 
ORIGINAL ISSUE DISCOUNT CONSEQUENCES OF THE NOTES
   
  The Original Notes were, and the Exchange Notes will be, sold with original
issue discount ("OID") for United States federal income tax purposes. Thus,
although cash interest will not be payable on the Notes prior to 2002, the
holders of the Notes (including cash basis holders) that are subject to U.S.
federal income taxation will be required to include such OID in income, on a
constant yield to maturity method basis, in advance of the receipt of the cash
payments to which such income is attributable. See "Certain Federal Income Tax
Considerations" for a more detailed discussion of the U.S. federal income tax
consequences to the U.S. Holders of the Notes of the purchase, ownership and
disposition of the Notes.     
 
                                      20
<PAGE>
 
                                USE OF PROCEEDS
   
  There will be no proceeds to the Company from the Exchange Offer. The net
proceeds of the Initial Offering were approximately $120.6 million. The net
proceeds were or are expected to be used as follows: (i) $20.0 million was
used to pay the cash portion of the 4-Sight Acquisition, (ii) approximately
$25.0 million was used to repay the Revolving Credit Facility and (iii) the
balance is being, and will be, used to further the Company's business
development and expansion strategy, to enhance the WAM!NET Service
infrastructure and develop additional value-added features and services, to
optimize marketing, sales and customer support and service capabilities, and
for working capital and other general corporate purposes. The Revolving Credit
Facility matures and becomes payable on September 23, 2000. At December 31,
1997, the aggregate principal amount outstanding under the Revolving Credit
Facility was $18.8 million, which bore interest at a rate equal to LIBOR (as
defined herein) plus 55 basis points per annum (6.27% at December 31, 1997).
The proceeds of the Revolving Credit Facility were used for equipment
purchases and working capital purposes. As of June 30, 1998, the aggregate
principal amount outstanding under the Revolving Credit Facility was $0. The
Company believes that the net proceeds of the Initial Offering and currently
contemplated financings, together with expected cash from operations, will be
sufficient to fund the Company's operations through September 30, 1999
(through March 31, 1999 without such financings). See "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and
"Description of Certain Indebtedness" for a discussion of the Company's
funding requirements.     
 
  Pending such utilization, the Company invests the net proceeds of the
Initial Offering in short-term investment grade and government securities.

                              THE EXCHANGE OFFER
 
PURPOSE OF THE EXCHANGE OFFER
 
  The sole purpose of the Exchange Offer is to fulfill the obligations of the
Company with respect to the Registration Rights Agreement.
 
  The Original Notes were originally issued and sold on March 5, 1998. Such
sales were not registered under the Securities Act (i) in reliance upon the
exemption provided by Section 4(2) of the Securities Act and Rule 144A of the
Securities Act, and (ii) pursuant to offers and sales that occurred outside
the United States within the meaning of Regulation S under the Securities Act.
Pursuant to the Registration Rights Agreement, the Company agreed to file with
the Commission the Exchange Offer Registration Statement on an appropriate
form under the Securities Act with respect to an offer to exchange the
Original Notes for the Exchange Notes. Upon the effectiveness of the Exchange
Offer Registration Statement, the Company will offer to the holders of
Original Notes who are able to make certain representations the opportunity to
exchange their Original Notes for Exchange Notes. If (i) the Company is not
permitted to file the Exchange Offer Registration Statement or to consummate
the Exchange Offer because the Exchange Offer is not permitted by applicable
law or Commission policy, (ii) the Exchange Offer is not for any other reason
consummated within 180 days after the Issue Date, (iii) any holder of Original
Notes notifies the Company within a specified time period that (a) due to a
change in law or policy it is not entitled to participate in the Exchange
Offer, (b) due to a change in law or policy it may not resell the Exchange
Notes acquired by it in the Exchange Offer to the public without delivering a
prospectus and (x) the prospectus contained in the Exchange Offer Registration
Statement is not appropriate or available for such resales by such holder and
(y) such prospectus is not promptly amended or modified in order to be
suitable for use in connection with such resales for such holder and all
similarly situated holders or (c) it is a broker-dealer and owns Original
Notes acquired directly from the Company or an affiliate of the Company or
(iv) the holders of a majority of the Original Notes may not resell the
Exchange Notes acquired by them in the Exchange Offer to the public without
restriction under the Securities Act and without restriction under applicable
blue sky or state securities laws, the Company will file with the Commission
the Shelf Registration Statement to cover resales of the Transfer Restricted
Notes (as defined below) by the holders thereof. The Company agreed to use its
best efforts to cause the applicable registration statement to be declared
effective as promptly as possible by the Commission. For purposes of the
foregoing, "Transfer Restricted Notes" means each Original Note until (i) the
date on which such Original Note has been exchanged by a person other than a
broker-dealer for an Exchange Note in the Exchange Offer, (ii) following the
exchange by a broker-dealer in the Exchange Offer of an Original Note for an
Exchange Note, the date on which such Exchange Note is sold to a purchaser who
receives from such broker-dealer on or prior to the date of such sale a copy
of the prospectus contained in the Exchange Offer Registration Statement,
(iii) the date on which such Original Note has been effectively registered
under the Securities Act and disposed of in accordance with the Shelf
Registration Statement, (iv) the date on which such Original Note is
distributed to the public pursuant to Rule 144(k) under the Securities Act (or
any similar provision then in force, but not Rule 144A under the Securities
Act), (v) such Original Note shall have been otherwise transferred by the
holder thereof and a new Note not bearing a legend restricting further
transfer shall have been delivered by the Company and subsequent disposition
of such Note shall not require registration or qualification under the
Securities Act or any similar state law then in force or (vi) such Original
Note ceases to be outstanding.
 
  The Registration Rights Agreement provides that: (i) unless the Exchange
Offer would not be permitted by applicable law or Commission policy, the
Company will file the Exchange Offer Registration Statement with the
Commission on or prior to the 90th day after the Issue Date, (ii) unless the
Exchange Offer would not be permitted by applicable law or Commission policy,
the Company will use its best efforts to have the Exchange Offer Registration
Statement declared effective by the Commission on or prior to the 150th day
after the Issue Date (the "Target Effectiveness Date"), (iii) unless the
Exchange Offer would not be permitted by applicable law or Commission policy,
the Company will commence the Exchange Offer and use its best efforts to
issue, on or prior to the date which is 30 days after the date on which the
Exchange Offer Registration Statement was declared effective by the
Commission, Exchange Notes in Exchange for all Original Notes tendered prior
thereto
 
                                      22
<PAGE>
 
in the Exchange Offer and (iv) if obligated to file the Shelf Registration
Statement, the Company will use its best efforts to file prior to the later of
(a) the 90th day after the Issue Date or (b) the 30th day after such filing
obligation arises and will use its best efforts to cause the Shelf
Registration Statement to be declared effective by the Commission on or prior
to the 60th day after such obligation arises; provided that if the Company has
not consummated the Exchange Offer within the date which is 180 days after the
Issue Date, then the Company will file the Shelf Registration Statement with
the Commission on or prior to the 30th day after such date. The Company shall
use its best efforts to keep such Shelf Registration Statement continuously
effective, supplemented and amended until the earlier of (i) the second
anniversary of the effective date of the Shelf Registration Statement and (ii)
such time as all of the Transfer Restricted Notes covered by the Shelf
Registration Statement have been sold thereunder or otherwise cease to be
Transfer Restricted Notes. If (i) the Company fails to file any of the
registration statements required by the Registration Rights Agreement on or
before the date specified for such filing, (ii) any of such registration
statements is not declared effective by the Commission on or prior to the
Target Effectiveness Date (subject to certain limited exceptions), (iii) the
Company fails to consummate the Exchange Offer within 30 days of the Target
Effectiveness Date with respect to the Exchange Offer Registration Statement,
or (iv) the Shelf Registration Statement or the Exchange Offer Registration
Statement is declared effective but thereafter, subject to certain limited
exceptions, ceases to be effective or usable in connection with the Exchange
Offer or resales of Transfer Restricted Notes, as the case may be, during the
periods specified in the Registration Rights Agreement (each such event
referred to in clauses (i) through (iv) above, a "Registration Default"), then
the Company shall pay as liquidated damages interest on the Transfer
Restricted Notes as to which any Registration Default exists. If a
Registration Default exists with respect to Transfer Restricted Notes, the
Company will, with respect to the first 90-day period (or portion thereof)
while such Registration Default is continuing immediately following the
occurrence of such Registration Default, make cash payments at a rate of .50%
per annum multiplied by the Accreted Value of the Transfer Restricted Notes as
of the date such payment is required to be made. The rate of such cash payment
shall increase by an additional .50% per annum at the beginning of each
subsequent 90-day period (or portion thereof) while such Registration Default
is continuing until such Registration Default is cured, up to a maximum rate
of 1.5% per annum. Following the cure of all Registration Defaults, the making
of cash payments with respect to the Notes will cease and the interest rate on
the Notes will revert to zero. See "Note Registration Rights."
 
TERMS OF THE EXCHANGE
 
  The Company hereby offers to exchange, upon the terms and subject to the
conditions set forth herein and in the Letter of Transmittal, $1,000 in
principal amount of Exchange Notes for each $1,000 in principal amount of the
Original Notes. The terms of the Exchange Notes are identical in all respects
to the terms of the Original Notes for which they may be exchanged pursuant to
this Exchange Offer, except that the Exchange Notes will generally be freely
transferable by holders thereof ("Holders"), and the Holders of the Exchange
Notes (as well as remaining Holders of any Original Notes) will not be
entitled to registration rights under the Registration Rights Agreement. The
Exchange Notes will evidence the same debt as the Original Notes and will be
entitled to the benefits of the Indenture. See "Description of the Notes."
 
  The Exchange Offer is not conditioned upon any minimum aggregate principal
amount of Original Notes being tendered for exchange.
 
  Based on interpretations by the Staff set forth in no-action letters issued
to third parties, the Company believes that Exchange Notes issued pursuant to
the Exchange Offer in exchange for the Original Notes may be offered for
resale, resold and otherwise transferred by Holders thereof (other than any
Holder which is (i) an "affiliate" of the Company within the meaning of Rule
405 under the Securities Act, (ii) a broker-dealer who acquired Original Notes
directly from the Company or (iii) broker-dealers who acquired Original Notes
as a result of market making or other trading activities) 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
Holder's business, and such Holders are not engaged in, and do not intend to
engage in, and have no arrangement or understanding with any person to
participate in, a distribution of such Exchange Notes. If a Holder is not a
broker-dealer, it will be required to represent that it is not engaged in, and
does not intend to engage in,
 
                                      23
<PAGE>
 
   
a distribution of the Exchange Notes. Each broker-dealer that receives
Exchange Notes pursuant to the Exchange Offer may be a statutory underwriter
and, therefore, must acknowledge that it will deliver a current prospectus
meeting the requirements of the Securities Act 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. Broker-dealers who acquired Original Notes as a result of
market making or other trading activities may use this Prospectus, as
supplemented or amended, in connection with resales of the Exchange Notes. The
Company have agreed that, for a period not to exceed 180 days after the
Exchange Date, they will make this Prospectus available to any broker-dealer
for use in connection with any such resale. Any Holder that cannot rely upon
such interpretations must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with a secondary resale
transaction.     
 
  Tendering Holders of Original Notes 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 the Original Notes
pursuant to the Exchange Offer.
   
  Accreted value on the Exchange Notes will accrue from the Issue Date.
Holders whose Original Notes are accepted for exchange will not receive
accreted value thereon, but because the accreted value of the Exchange Notes
is calculated from the date of issuance of the Original Notes, there will be
no forfeiture of accreted value, or interest (which does not begin accruing
until March 1, 2002), by the holders of Original Notes whose Notes are
accepted for exchange in the Exchange Offer.     
 
EXPIRATION DATE; EXTENSIONS; TERMINATION; AMENDMENTS
 
  The Exchange Offer expires on the Expiration Date. The term "Expiration
Date" means 5:00 p.m., New York City time, on      , 1998, unless the Company
in its sole discretion extend the period during which the Exchange Offer is
open, in which event the term "Expiration Date" means the latest time and date
on which the Exchange Offer, as so extended by the Company, expires. The
Company reserves the right to extend the Exchange Offer at any time and from
time to time prior to the Expiration Date by giving written notice to U.S.
Bank Trust National Association (f/k/a First Trust National Association) (the
"Exchange Agent") and by timely public announcement communicated, unless
otherwise required by applicable law or regulation, by making a release to the
Dow Jones News Service. During any extension of the Exchange Offer, all
Original Notes previously tendered pursuant to the Exchange Offer will remain
subject to the Exchange Offer.
 
  The initial Exchange Date will be the first business day following the
Expiration Date. The Company expressly reserves the right to (i) terminate the
Exchange Offer and not accept for exchange any Original Notes for any reason,
including if any of the events set forth below under "--Conditions to the
Exchange Offer" shall have occurred and shall not have been waived by the
Company and (ii) amend the terms of the Exchange Offer in any manner, whether
before or after any tender of the Original Notes. If any such termination or
amendment occurs, the Company will notify the Exchange Agent in writing and
will either issue a press release or give written notice to the Holders of the
Original Notes as promptly as practicable. Unless the Company terminates the
Exchange Offer prior to 5:00 p.m., New York City time, on the Expiration Date,
the Company will exchange the Exchange Notes for the Original Notes on the
Exchange Date.
 
  If the Company waives any material condition to the Exchange Offer, or amend
the Exchange Offer in any other material respect, and if at the time that
notice of such waiver or amendment is first published, sent or given to
Holders of Original Notes in the manner specified above, the Exchange Offer is
scheduled to expire at any time earlier than the expiration of a period ending
on the fifth business day from, and including, the date that such notice is
first so published, sent or given, then the Exchange Offer will be extended
until the expiration of such period of five business days.
 
  This Prospectus and the related Letter of Transmittal and other relevant
materials will be mailed by the Company to record Holders of Original Notes
and will be furnished to brokers, banks and similar persons whose names, or
the names of whose nominees, appear on the lists of Holders for subsequent
transmittal to beneficial owners of Original Notes.
 
                                      24

HOW TO TENDER
 
  The tender to the Company of Original Notes by a Holder thereof pursuant to
one of the procedures set forth below 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.
 
  General Procedures. A Holder of an Original Note may tender the same by (i)
properly completing and signing the Letter of Transmittal or a facsimile
thereof (all references in this Prospectus to the Letter of Transmittal shall
be deemed to include a facsimile thereof) and delivering the same, together
with the certificate or certificates representing the Original Notes being
tendered and any required signature guarantees (or a timely confirmation of a
book-entry transfer (a "Book-Entry Confirmation") pursuant to the procedure
described below), to the Exchange Agent at its address set forth on the back
cover of this Prospectus on or prior to the Expiration Date or (ii) complying
with the guaranteed delivery procedures described below.
 
  If tendered Original Notes are registered in the name of the signer of the
Letter of Transmittal and the Exchange Notes to be issued in exchange therefor
are to be issued (and any untendered Original Notes are to be reissued) in the
name of the registered Holder, the signature of such signer need not be
guaranteed. In any other case, the tendered Original Notes must be endorsed or
accompanied by written instruments of transfer in form satisfactory to the
Company and duly executed by the registered Holder and the signature on the
endorsement or instrument of transfer must be guaranteed by a firm (an
"Eligible Institution") that is a member of a recognized signature guarantee
medallion program within the meaning of Rule 17Ad-15 under the Exchange Act.
If the Exchange Notes and/or Original Notes not exchanged are to be delivered
to an address other than that of the registered Holder appearing on the note
register for the Original Notes, the signature on the Letter of Transmittal
must be guaranteed by an Eligible Institution.
 
  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 Original Notes should contact such Holder promptly and instruct such
Holder to tender Original Notes on such beneficial owner's behalf. If such
beneficial owner wishes to tender such Original Notes himself, such beneficial
owner must, prior to completing and executing the Letter of Transmittal and
delivering such Original Notes, either make appropriate arrangements to
register ownership of the Original Notes in such beneficial owner's name or
follow the procedures described in the immediately preceding paragraph. The
transfer of record ownership may take considerable time.
 
  Book-Entry Transfer. The Exchange Agent will make a request to establish an
account with respect to the Original Notes at The Depository Trust Company
(the "Book-Entry Transfer Facility") for purposes of the Exchange Offer within
two business days after receipt of this Prospectus, and any financial
institution that is a participant in the Book-Entry Transfer Facility's
systems may make book-entry delivery of Original Notes by causing the Book-
Entry Transfer Facility to transfer such Original Notes into the Exchange
Agent's account at the Book-Entry Transfer Facility in accordance with the
Book-Entry Transfer Facility's procedures for transfer. However, although
delivery of Original Notes may be effected through book-entry transfer at the
Book-Entry Transfer Facility, the Letter of Transmittal, 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 specified on
the back cover page of this Prospectus on or prior to the Expiration Date or
the guaranteed delivery procedures described below must be complied with.
 
  THE METHOD OF DELIVERY OF ORIGINAL NOTES AND ALL OTHER DOCUMENTS IS AT THE
ELECTION AND RISK OF THE HOLDER. IF SENT BY MAIL, IT IS RECOMMENDED THAT
REGISTERED MAIL, RETURN RECEIPT REQUESTED, BE USED, PROPER INSURANCE BE
OBTAINED, AND THE MAILING BE MADE SUFFICIENTLY IN ADVANCE OF THE EXPIRATION
DATE TO PERMIT DELIVERY TO THE EXCHANGE AGENT ON OR BEFORE THE EXPIRATION
DATE.
 
  Unless an exemption applies under the applicable law and regulations
concerning "backup withholding" of federal income tax, the Exchange Agent will
be required to withhold, and will withhold, 31% of the gross proceeds
otherwise payable to a Holder pursuant to the Exchange Offer if the Holder
does not provide his taxpayer identification number (social security number or
employer identification number) and certify that such
 
                                      25
<PAGE>
 
number is correct. Each tendering Holder should complete and sign the main
signature form and the Substitute Form W-9 included as part of the Letter of
Transmittal, so as to provide the information and certification necessary to
avoid backup withholding, unless an applicable exemption exists and is proved
in a manner satisfactory to the Company and the Exchange Agent.
 
  Guaranteed Delivery Procedures. If a Holder desires to accept the Exchange
Offer and time will not permit a Letter of Transmittal or Original Notes to
reach the Exchange Agent before the Expiration Date, a tender may be effected
if the Exchange Agent has received at its office listed on the back cover
hereof on or prior to the Expiration Date a letter, telegram or facsimile
transmission from an Eligible Institution setting forth the name and address
of the tendering Holder, the names in which the Original Notes are registered
and, if possible, the certificate numbers of the Original Notes to be
tendered, and stating that the tender is being made thereby and guaranteeing
that within five New York Stock Exchange trading days after the date of
execution of such letter, telegram or facsimile transmission by the Eligible
Institution, the Original Notes, in proper form for transfer, will be
delivered by such Eligible Institution together with a properly completed and
duly executed Letter of Transmittal (and any other required documents). Unless
Original Notes being tendered by the above-described method (or a timely Book-
Entry Confirmation) are deposited with the Exchange Agent within the time
period set forth above (accompanied or preceded by a properly completed Letter
of Transmittal and any other required documents), the Company may, at its
option, reject the tender. Copies of a Notice of Guaranteed Delivery which may
be used by Eligible Institutions for the purposes described in this paragraph
are being delivered with this Prospectus and the related Letter of
Transmittal.
 
  A tender will be deemed to have been received as of the date when the
tendering Holder's properly completed and duly signed Letter of Transmittal
accompanied by the Original Notes (or a timely Book-Entry Confirmation) is
received by the Exchange Agent. Issuances of Exchange Notes in exchange for
Original Notes tendered pursuant to a Notice of Guaranteed Delivery or letter,
telegram or facsimile transmission to similar effect (as provided above) by an
Eligible Institution will be made only against deposit of the Letter of
Transmittal (and any other required documents) and the tendered Original Notes
(or a timely Book-Entry Confirmation).
 
  All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for exchange of any tender of Original Notes will be
determined by the Company, whose determination will be final and binding. The
Company reserves the absolute right to reject any or all tenders not in proper
form or the acceptances for exchange of which may, in the opinion of counsel
to the Company, be unlawful. The Company also reserves the absolute right to
waive any of the conditions of the Exchange Offer or any defect or
irregularities in tenders of any particular Holder whether or not similar
defects or irregularities are waived in the case of other Holders. None of the
Company, the Exchange Agent or any other person will be under any duty to give
notification of any defects or irregularities in tenders or shall incur any
liability for failure to give any such notification. The Company's
interpretation of the terms and conditions of the Exchange Offer (including
the Letter of Transmittal and the instructions thereto) will be final and
binding.
 
TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL
 
  The Letter of Transmittal contains, among other things, the following terms
and conditions, which are part of the Exchange Offer.
 
  The party tendering Original Notes for exchange (the "Transferor")
exchanges, assigns and transfers the Original Notes to the Company and
irrevocably constitutes and appoints the Exchange Agent as the Transferor's
agent and attorney-in-fact to cause the Original Notes to be assigned,
transferred and exchanged. The Transferor represents and warrants that it has
full power and authority to tender, exchange, assign and transfer the Original
Notes and to acquire Exchange Notes issuable upon the exchange of such
tendered Original Notes, and that, when the same are accepted for exchange,
the Company will acquire good and unencumbered title to the tendered Original
Notes, free and clear of all liens, restrictions, charges and encumbrances and
not subject to any adverse claim. The Transferor also warrants that it will,
upon request, execute and deliver any additional documents deemed by the
Company to be necessary or desirable to complete the exchange, assignment and
transfer of
 
                                      26
<PAGE>
 
tendered Original Notes. The Transferor further agrees that acceptance of any
tendered Original Notes by the Company and the issuance of Exchange Notes in
exchange therefor shall constitute performance in full by the Company of its
obligations under the Registration Rights Agreement and that the Company shall
have no further obligations or liabilities thereunder (except in certain
limited circumstances). All authority conferred by the Transferor will survive
the death or incapacity of the Transferor and every obligation of the
Transferor shall be binding upon the heirs, legal representatives, successors,
assigns, executors and administrators of such Transferor.
 
  By tendering Original Notes, the Transferor certifies (a) that it is not an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act, that it is not a broker-dealer that owns Original Notes acquired directly
from the Company or an affiliate of the Company, that it is acquiring the
Exchange Notes offered hereby in the ordinary course of such Transferor's
business and that such Transferor has no arrangement with any person to
participate in the distribution of such Exchange Notes or (b) that it is an
"affiliate" (as defined) of the Company or of the initial purchasers in the
Initial Offering of the Original Notes, and that it will comply with the
registration and prospectus delivery requirements of the Securities Act to the
extent applicable to it.
 
WITHDRAWAL RIGHTS
 
  Original Notes tendered pursuant to the Exchange Offer may be withdrawn at
any time prior to the Expiration Date.
 
  For a withdrawal to be effective, a written or facsimile transmission notice
of withdrawal must be timely received by the Exchange Agent at its address set
forth on the back cover of this Prospectus. Any such notice of withdrawal must
specify the person named in the Letter of Transmittal as having tendered
Original Notes to be withdrawn, the certificate numbers of Original Notes to
be withdrawn, the principal amount of Original Notes to be withdrawn (which
must be an authorized denomination), a statement that such Holder is
withdrawing his election to have such Original Notes exchanged, and the name
of the registered Holder of such Original Notes, and must be signed by the
Holder in the same manner as the original signature on the Letter of
Transmittal (including any required signature guarantees) or be accompanied by
evidence satisfactory to the Company that the person withdrawing the tender
has succeeded to the beneficial ownership of the Original Notes being
withdrawn. The Exchange Agent will return the properly withdrawn Original
Notes promptly following receipt of notice of withdrawal. All questions as to
the validity of notices of withdrawals, including time of receipt, will be
determined by the Company, and such determination will be final and binding on
all parties.
 
ACCEPTANCE OF ORIGINAL NOTES FOR EXCHANGE; DELIVERY OF EXCHANGE NOTES
 
  Upon the terms and subject to the conditions of the Exchange Offer, the
acceptance for exchange of Original Notes validly tendered and not withdrawn
and the issuance of the Exchange Notes will be made on the Exchange Date. For
the 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 has given 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 Exchange Notes from the Company and
causing the Original Notes to be assigned, transferred and exchanged. Upon the
terms and subject to the conditions of the Exchange Offer, delivery of
Exchange Notes to be issued in exchange for accepted Original Notes will be
made by the Exchange Agent promptly after acceptance of the tendered Original
Notes. Original Notes not accepted for exchange by the Company will be
returned without expense to the tendering Holders (or in the case of Original
Notes tendered by book-entry transfer into the Exchange Agent's account at the
Book-Entry Transfer Facility pursuant to the procedures described above, such
non-exchanged Original Notes will be credited to an account maintained with
such Book-Entry Transfer Facility) promptly following the Expiration Date or,
if the Company terminates the Exchange Offer prior to the Expiration Date,
promptly after the Exchange Offer is so terminated.
 
                                      27
<PAGE>
 
CONDITIONS TO THE EXCHANGE OFFER
 
  Notwithstanding any other provision of the Exchange Offer, or any extension
of the Exchange Offer, the Company will not be required to issue Exchange
Notes in respect of any properly tendered Original Notes not previously
accepted and may terminate the Exchange Offer (by oral or written notice to
the Exchange Agent and by timely public announcement communicated, unless
otherwise required by applicable law or regulation, by making a release to the
Dow Jones News Service) or, at its option, modify or otherwise amend the
Exchange Offer, if (a) there shall be threatened, instituted or pending any
action or proceeding before, or any injunction, order or decree shall have
been issued by, any court or governmental agency or other governmental
regulatory or administrative agency or commission, (i) seeking to restrain or
prohibit the making or consummation of the Exchange Offer or any other
transaction contemplated by the Exchange Offer, (ii) assessing or seeking any
damages as a result thereof, or (iii) resulting in a material delay in the
ability of the Company to accept for exchange or exchange some or all of the
Original Notes pursuant to the Exchange Offer; (b) any statute, rule,
regulation, order or injunction shall be sought, proposed, introduced,
enacted, promulgated or deemed applicable to the Exchange Offer or any of the
transactions contemplated by the Exchange Offer by any government or
governmental authority, domestic or foreign, or any action shall have been
taken, proposed or threatened, by any government, governmental authority,
agency or court, domestic or foreign, that in the sole judgment of the Company
might directly or indirectly result in any of the consequences referred to in
clauses (a)(i) or (ii) above or, in the sole judgment of the Company, might
result in the Holders of Exchange Notes having obligations with respect to
resales and transfers of Exchange Notes which are greater than those described
in the interpretations of the Commission referred to on the cover page of this
Prospectus, or would otherwise make it inadvisable to proceed with the
Exchange Offer; or (c) a material adverse change shall have occurred in the
business, condition (financial or otherwise), operations, or prospects of the
Company.
 
  The foregoing conditions are for the sole benefit of the Company and may be
asserted by it with respect to all or any portion of the Exchange Offer
regardless of the circumstances (including any action or inaction by the
Company) giving rise to such condition or may be waived by the Company in
whole or in part at any time or from time to time in its sole discretion. The
failure by the Company at any time to exercise any of the foregoing rights
will not be deemed a waiver of any such right, and each right will be deemed
an ongoing right which may be asserted at any time or from time to time. In
addition, the Company has reserved the right, notwithstanding the satisfaction
of each of the foregoing conditions, to terminate or amend the Exchange Offer.
 
  Any determination by the Company concerning the fulfillment or non-
fulfillment of any conditions will be final and binding upon all parties.
 
  In addition, the Company will not accept for exchange any Original Notes
tendered and no Exchange Notes will be issued in exchange for any such
Original Notes, if at such time any stop order shall be threatened or in
effect with respect to the Registration Statement of which this Prospectus
constitutes a part or qualification of the Indenture under the Trust Indenture

set forth on the back cover page of this Prospectus.

has been no change in the affairs of the Company since the respective dates as
of which information is given herein. The Exchange Offer is not being made to
(nor will tenders be accepted from or on behalf of) Holders of Original Notes
in any jurisdiction in which the making of the Exchange Offer or the
acceptance thereof would not be in compliance with the laws of such
jurisdiction. However, the Company may, at their discretion, take such action

carefully consider whether to accept. Holders of the Original Notes are urged
to consult their financial and tax advisors in making their own decisions on
what action to take.
 
  As a result of the making of, and upon acceptance for exchange of all
validly tendered Original Notes pursuant to the terms of this Exchange Offer,
the Company will have fulfilled a covenant contained in the terms of the
Original Notes and the Registration Rights Agreement. Holders of the Original
Notes who do not tender their certificates in the Exchange Offer will continue
to hold such certificates and will be entitled to all the rights, and
limitations applicable thereto, under the Indenture, except for any such
rights under the Registration Rights Agreement, which by their terms terminate
or cease to have further effect as a result of the making of this Exchange
Offer. See "Description of the Notes." All untendered Original Notes will
continue to be subject to the restriction on transfer set forth in the
Indenture. To the extent that Original Notes are tendered and accepted in the
Exchange Offer, the trading market, if any, for the Original Notes could be
adversely affected. See "Risk Factors--Consequences of Failure to Exchange."
 
  The Company may in the future seek to acquire untendered Original Notes in
open market or privately negotiated transactions, through subsequent exchange
offers or otherwise. The Company has no present plan to acquire any Original
Notes which are not tendered in the Exchange Offer.

    Sight mortgage of $332, and the payment of $20,000 to shareholders of 4-
    Sight and $500 for related expenses in connection with the acquisition of
    4-Sight.
(4) The estimated value of warrants issued to debtholders and of options
    issued to consultants is reflected as both a debt discount and an element
    of additional paid-in capital.
(5) Interest is payable semiannually in kind. WorldCom has agreed to defer all
    cash payments on such indebtedness until a date that is 180 days following
    the Stated Maturity of the Notes. See "Description of Certain

(6) Dividends are payable quarterly in kind. WorldCom has agreed that no cash
    dividends or distributions will be payable by the Company on the Class A
    Preferred Stock owned by WorldCom, and the Class A Preferred Stock owned
    by WorldCom will not be redeemed by the Company for cash, until a date
    that is 180 days following the Stated Maturity of the Notes. WorldCom is
    the sole holder of shares of Class A Preferred Stock. See "Description of
    Certain Indebtedness."

                            SELECTED FINANCIAL DATA
 
  The following tables set forth (i) selected historical consolidated
financial data for the Company and its subsidiaries for each of the years in
the three year period ended December 31, 1997, and for the three month periods
ended March 31, 1997 and 1998 and (ii) selected historical consolidated
financial data for 4-Sight and its subsidiaries for the year ended August 31,
1996, the month ended September 30, 1996, the year ended September 30, 1997,
and the twelve months ended December 31, 1997. The 4-Sight Acquisition
occurred on March 13, 1998 and the operating results of 4-Sight are included
in the Company's operating results from that date through March 31, 1998. The
Company's selected historical consolidated financial data as of and for the
three months ended March 31, 1997 and 1998 and 4-Sight's selected historical
consolidated financial data as of and for the twelve months ended December 31,
1997 have been derived from the respective companies' unaudited financial
statements and have been prepared on the same basis as the historical
information derived from audited financial statements. In the opinion of the
management of the Company and the management of 4-Sight, the unaudited
financial statements of the respective companies, from which such data have
been derived, contain all adjustments, consisting only of normal recurring
accruals, necessary for the fair presentation of the results for and as of the
end of such periods. The historical data with respect to the three months
ended March 31, 1998 should not be regarded as necessarily indicative of the
results that may be expected for the entire year. The Company's development
and expansion activities during the periods presented below significantly
affect the period-to-period comparability of the historical data presented for
the Company. The following information is qualified in its entirety by, and
should be read in conjunction with, the consolidated financial statements and
the notes thereto of the Company and 4-Sight and "Management's Discussion and
Analysis of Financial Condition and Results of Operations" included elsewhere
herein.

(1) EBITDA represents earnings (loss) from operations before taking into
    consideration net interest expense, income tax expense, depreciation
    expense and amortization expense. The Company has included information
    concerning EBITDA here as it is used by certain investors as a measure of
    a company's ability to service its debt. EBITDA should not be considered
    as an alternative to net income or any other measure of performance or
    liquidity as determined in accordance with generally accepted accounting
    principles or as an indicator of the Company's overall financial
    performance. In addition, the measure of EBITDA presented herein by the
    Company may not be comparable to other similarly titled measures of other
    companies.     
   
(2) The ratio of earnings to fixed charges is calculated by dividing (i) net
    income (loss) before taxes plus fixed charges by (ii) fixed charges. Fixed
    charges consist of interest incurred and the portion of rent expense which
    is deemed representative of interest. The Company's earnings were
    insufficient to cover fixed charges by $1,242, $6,653 and $29,180 for the
    years ended December 31, 1995, 1996 and 1997, and $3,907 and $23,184 for
    the three month periods ended March 31, 1997 and 1998, respectively.
    Earnings were insufficient to cover fixed charges by $0.04 for 4-Sight for
    the one month period ended September 30, 1996.     
(3) Total debt includes long-term debt, current portion of long-term debt and
    obligations under capitalized leases, net of the unamortized value of
    warrants ($3,679) issued to debtholders.
(4) The estimated value of warrants issued to debtholders and of options
    issued to consultants is reflected as both a debt discount and an element
    of paid in capital.
(5) 4-Sight changed its fiscal year end to September 30 during 1997.
(6) 4-Sight's fiscal year ends on September 30. The financial data of 4-Sight
    for the twelve months ended December 31, 1997 is presented for comparative
    purposes.

                           PRO FORMA FINANCIAL DATA
   
  The following unaudited pro forma financial data (the "Pro Forma Financial
Data") of the Company has been derived from and should be read in conjunction
with (i) the audited consolidated financial statements of the Company and the
related notes thereto, included elsewhere herein, which statements have been
audited by Ernst & Young LLP, independent auditors, whose report is included
elsewhere herein, and (ii) the audited consolidated financial statements of 4-
Sight and the related notes thereto included elsewhere herein, which
statements have been audited by Ernst & Young, Chartered Accountants,
independent auditors, whose report is included elsewhere herein. The unaudited
financial statements of 4-Sight for the twelve month period ended December 31,
1997 have been derived by removing the unaudited results of the three month
period ended December 31, 1996 from the audited statement of operations for
the year ended September 30, 1997 and adding the unaudited results for the
three month period ended December 31, 1997. The Pro Forma Financial Data has
been prepared to illustrate the effects of the 4-Sight Acquisition and the
Initial Offering, including the application of the net proceeds therefrom.
This Pro Forma Financial Data does not necessarily present the financial
position or results of operations as they would have been if the companies
involved had constituted one entity for the period presented. See "Prospectus
Summary--Recent Developments" and "Use of Proceeds."     
   
  The pro forma statement of operations data for the twelve month period ended
December 31, 1997 and the three month period ended March 31, 1998 gives effect
to the 4-Sight Acquisition and the Initial Offering as if they had occurred at
the beginning of the respective period. The Pro Forma Financial Data is not
necessarily indicative of either future results of operations or the results
that might have occurred if the foregoing transactions had been consummated on
the indicated date.     
 
  The acquisition of 4-Sight was accounted for using the purchase method.
After the acquisition, the total purchase price of the acquisition was
allocated to the assets and liabilities based upon the estimated fair value of
the assets and liabilities acquired. The actual purchase accounting
adjustments were not materially different from the pro forma adjustments.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
   
  The following discussion and analysis is based on the historical and pro
forma results of the Company and should be read in conjunction with the
Company's Financial Statements and "Pro Forma Financial Data" included herein.
    
OVERVIEW
 
  The Company was organized in September 1994 and commenced operations in
March 1995. From March 1995 through February 1996, the Company was engaged
primarily in the design and development of the WAM!NET Network and the WAM!NET
Service. The Company announced the commercial release of the WAM!NET Service
in February 1996 at a major Graphic Arts industry trade show. Through March
31, 1998, approximately 830 customers had contracted for the WAM!NET Service
at a total of 1,370 customer sites. As of that date, the WAM!NET Service had
been installed at 816 customer sites, with the balance of the contracted sites
expected to be installed during the first half of 1998.
   
  The Company has entered into a strategic alliance with WorldCom that
includes equity and debt investments and operating loan guarantees totaling
approximately $50 million. WorldCom is currently entitled to designate a
majority of the Board of Directors of the Company and, through its ownership
of convertible debt and warrants, has the right to acquire a majority of the
Common Stock of the Company. WorldCom also provides telecommunication and
other services to the Company on a nonexclusive basis. The Company anticipates
that its relationship with WorldCom will enable it to access the worldwide
infrastructure, sales and marketing work force, telephony technologies, high
bandwidth carrier service and other services of WorldCom and its affiliates,
including UUNet.     
 
  On March 13, 1998, the Company consummated the purchase of 4-Sight. 4-Sight
develops and distributes ISDN data transmission software and related products
and applications targeted to the Graphic Arts industry, with particular
emphasis on European, Asian and North American markets. At December 31, 1997,
4-Sight's customer base exceeded 30,000 locations, including 3,000 sites in
the United States. The Company expects that the 4-Sight Acquisition will
enable the Company to achieve broader market coverage in the Graphic Arts
market by combining 4-Sight's international presence and penetration of the
lower volume user market with the Company's domestic presence and penetration
of the higher volume user market.
 
  Due to costs associated with the design, development, installation and
operation of the WAM!NET Network and its related applications, the Company has
operated at a loss since inception and expects to incur substantial operating
losses for the years ending December 31, 1998 and 1999. The Company has
incurred an accumulated deficit of approximately $69,192 million through March
31, 1998.
   
  Revenue. The Company's revenue is derived primarily from WAM!NET Service
contracts which are usually annual, automatically renewable service contracts
with a minimum monthly fee and additional charges for usage exceeding the
monthly minimum. The Company offers the WAM!NET Service at scaled minimum
usage fees, generally ranging from $250 per month to $3,000 per month. Service
installation typically lags contract signing by approximately 90 days due to
the time required to obtain telephone service installation from local
telephone companies. The Company begins to earn gross revenue following
installation of service at a customer's premise. The Company also incurs
service rebates that offset the gross revenue generated by the Company. Free
trial periods under the Company's various promotional programs have ranged
from 60 days to six months and have been extended to 47.9% of the Company's
customer base to date. As a result, the Company's generation of net revenue
from any customer may lag contract signing by a period of three to nine
months, a practice that is not customary in the digital data delivery industry
but is a key component in the Company's market penetration strategy. The
Company's experience with promotional programs has been favorable to date,
with approximately 97% of customers continuing to subscribe to the WAM!NET
Service following expiration of the promotional period extended to them. The
Company expects the use of promotional programs in the Graphic Arts industry
to decline with increasing penetration of the market, but the Company     
 
                                      37
<PAGE>
 
will likely use similar promotional programs to introduce the WAM!NET Service
to its other targeted industries. The Company also plans to continue to
develop new, Industry Smart applications to increase the volume of files
transferred over the network.
 
  Revenue is primarily driven by the number of installed customer locations,
the length of time a customer has been using the service, the number of work
flow partners with whom a customer exchanges data and the size of the files
exchanged.
 
  Network Communications Fees. Network communications fees include both the
costs of the high bandwidth carrier services interconnecting the Company's
national infrastructure of NOCs and Distribution Hubs and the costs of local
telephone circuits connecting NADs to the nearest Distribution Hub. Local
telephone circuit ("last mile") connections account for approximately 60% of
these charges, with significant differences between urban and rural connection
costs. National carrier service, provided primarily by WorldCom, accounts for
most of the balance of these charges. Network communication fees are generally
a fixed monthly cost per circuit. The excess of these fees over revenue
represents excess capacity costs which the Company expects will decline with
increasing utilization of the WAM!NET Network. The Company actively seeks to
obtain and deploy technologies that will reduce the costs of last mile
connections, including wireless technologies and remote dial-up capabilities.
The Company also intends to use its network management tools to optimize
existing and planned network capacity as volume increases and traffic patterns
begin to emerge. The Company plans to consider new pricing for its services
which take into account the significant cost differential between urban and
rural last mile connections. The Company also believes it may benefit from
growing competition among telephony and communications providers for the
provision of last mile connectivity.
 
  Network Operations Expense. Network operations expense represents costs
directly associated with developing, maintaining, managing and servicing the
WAM!NET Network. Such costs include direct labor, vendor service fees, point-
of-presence charges and research and development charges which are often
incurred in advance of receiving revenue. The Company's currently installed
NOCs, which account for the substantial majority of direct labor and network
operating costs, are capable of providing for and managing the Company's
current and planned North American operations. Costs associated with the
development of WAM!BASE, WAM!PROOF and other network applications are also
contained in network operations expense and are incurred in advance of revenue
receipt. The Company expects that network operations costs will increase as
the WAM!NET Network expands; however, the cost of network operations as a
percentage of revenue is expected to decline.
 
  Sales and Marketing Expense. The Company's sales and marketing efforts are
intended to create awareness of the WAM!NET Service, communicate its potential
for work flow enhancement, demonstrate its reliability and establish strong
brand recognition. As a result, the Company aggressively markets the WAM!NET
Service through a combination of trade journal advertising, trade show
attendance, promotional programs, direct field sales, tele-sales, cooperative
sales presentations and active participation in industry sponsored seminars
and publications. The Company expects to continue to incur significant sales
and marketing expenses to obtain increased penetration of the Graphic Arts
industry, to generate increased traffic among customers and to market the
WAM!NET Service to other targeted industries.
 
  General and Administrative Expense. The Company's general and administrative
expense includes administrative salaries, related overhead and professional
service fees. These costs reflect expenditures related to the rapid growth and
expansion of the Company's administrative infrastructure necessary to manage
its expanding operations, costs incurred in 1997 for relocation to its new
administrative and network operations facility and professional service fees
for financing activities, contract negotiations and acquisitions. The Company
expects to continue to incur substantial general and administrative expense as
the Company deploys the WAM!NET Service internationally.
 
  Depreciation and Amortization. To facilitate entry into its target markets,
the Company furnishes its customers with all the hardware and software
necessary for them to use the WAM!NET Service on a turn-key,
 
                                      38
<PAGE>
 
   
pay-by-use basis. As a result, the Company retains ownership of the NADs it
furnishes to customers for their use of the WAM!NET Service. Accordingly, the
Company does not anticipate selling NADs (or other hardware and non-4-Sight
software) as a means of raising revenues. Depreciation and amortization
expense includes depreciation of NADs, Distribution Hubs and equipment located
in the NOCs. The Company's network infrastructure is organized to use the most
expensive equipment in the NOCs, less expensive equipment for Distribution
Hubs and the least expensive equipment in the NADs. The Company anticipates
substantial capital investments for additional Distribution Hubs to be located
in North America and internationally, WAM!BASE storage facilities to be
located in the existing NOCs and NADs to be located at customer premises. As a
result, the Company anticipates that depreciation and amortization expense
will continue to increase in future periods commensurate with future equipment
purchases.     
 
RESULTS OF OPERATIONS
 
THREE MONTH PERIOD ENDED MARCH 31, 1998 COMPARED WITH THREE MONTH PERIOD ENDED
MARCH 31, 1997
 
 Revenue
 
  Revenue from the WAM!NET Service for the three month period ended March 31,
1998 was $1,320,026, compared to $116,678 for the three month period ended
March 31, 1997, an increase of $1,203,348, or 1,031%. This increase was due to
a 486.3% increase in the number of subscribers to the WAM!NET Service from
approximately 153 installed customer sites on March 31, 1997 to approximately
744 installed customer sites on March 31, 1998. At March 31, 1998, the Company
had contracts to install NAD's at 625 customer sites awaiting installation of
telephony services. Service rebates for the three month period ended March 31,
1998 were $271,000, or 20.5% of revenue. Service rebates for the three month
period ended March 31, 1997 were $0.
 
  Revenue from software and hardware sales for the three month period ended
March 31, 1998 was $822,000, compared to $0 for the three month period ended
March 31, 1997. Revenues from software and hardware sales are a result of the
Company's acquisition of 4-Sight, which was consummated as of March 13, 1998.
 
  Other service fee revenue for the three month period ended March 31, 1998
was $9,000, compared to $5,108 for the three month period ending March 31,
1997, an increase of $3,892, or 76.2%. Other service fees revenue is primarily
derived from ancillary transactions with existing WAM!NET Service customers
which includes consulting services and hardware sales. The increase reflects a
minor increase in customer consulting hours during the three month period
ended March 31, 1998.
 
 Operating Expenses
 
  Network communications fees for the three month period ended March 31, 1998
were $3,151,571, compared to $862,369 for the three month period ended March
31, 1997, an increase of $2,289,202 or 376.7%. Network operations expense for
the three month period ended March 31, 1998 was $3,259,126, compared to
$848,834 for the three month period ended March 31, 1997, an increase of
$2,410,292 or 283.9%. These increases were primarily due to the 386.3%
increase in customers that subscribed to the WAM!NET Service during the three
month period ending March 31, 1998.
 
  Cost of software and hardware sales for the three month period ended March
31, 1998 was $261,000, compared to $0 for the three month period ended March
31, 1997. Costs of software and hardware sales are a result of the Company's
acquisition of 4-Sight, which was consummated as of March 13, 1998.
 
  Sales and marketing expenses for the three month period ended March 31, 1998
were $2,352,529, compared to $1,229,345 for the three month period ended March
31, 1997, an increase of $1,123,184, or 91.4%. This increase primarily
resulted from the costs associated with building the Company's direct sales
force and marketing department, and higher outside advertising agency and
trade show expenditures.

  General and administrative expense for the three month period ended March
31, 1998 was $14,466,910, compared to $977,318 for the three month period
ended March 31, 1997, an increase of $13,489,592, or 1,380.3%. This increase
is primarily due to a $11,423,502 non-cash charge relating to officer
compensation expense arising from the Company's election to accelerate the
vesting period for options granted to selected officers. The additional
increase in general and administrative expenses of $2,066,090 during the three
month period ended March 31, 1998 as compared to the three month period ending
March 31, 1997 was due to increased operational support requirements due to
the rapid expansion of the Company's services and corporate facilities.
 
  Depreciation and amortization for the three month period ended March 31,
1998 was $1,921,248, compared to $287,302 for the three month period ended
March 31, 1997, an increase of $1,633,946, or 568.72%. As a percentage of
gross WAM!NET Service revenue, depreciation and amortization was 246.2% in
1997, compared to 68.7% for the same period in 1998. This increase is
primarily due to an increase in the installed customer premise and
communications backbone equipment as a result of the increase in the number of
customers that are being provided with the WAM!NET Service.
 
  Interest expense for the three month period ended March 31, 1998 was
$3,444,282, compared to $778,297 for the three month period ended March 31,
1997, an increase of $2,665,985, or 342.5%. The increase was primarily due to
the Company's financing of its 1997 and 1998 operations through the issuance
of various debt instruments including $24 million of long-term subordinated
notes to WorldCom, $9.6 million of equipment financing and $208.5 million of
Notes issued in the Initial Offering.
 
 Income Taxes
   
  For the three months ended March 31, 1998, the Company experienced net
losses of $26,682,969 and paid no income taxes. These losses are available to
offset future taxable income through the year 2013 and are subject to the
limitations of Section 382 of the Internal Revenue Code of 1986, as amended.
These limitations may result in expiration of net operating loss carryforwards
before they can be utilized.     
 
YEAR ENDED DECEMBER 31, 1997 COMPARED WITH YEAR ENDED DECEMBER 31, 1996
 
 Revenue
 
  Revenue for the year ended December 31, 1997 was $1,627,590 compared to
$110,424 for the year ended December 31, 1996, an increase of $1,517,166, or
1,373.9%. This was primarily due to a 1,375.8% increase in the number of
subscribers to the WAM!NET Service from approximately 33 installed customer
sites on December 31, 1996 to approximately 487 installed customer sites on
December 31, 1997. At December 31, 1997, the Company had contracts to install
NADs at 578 customer sites awaiting installation of telephony services.
Service rebates for the year ended December 31, 1997 were $150,400, or 9.2% of
revenue. Service rebates for the year ended December 31, 1996 were $0.
 
  Other service fees revenue for the year ended December 31, 1997 was $77,748,
compared to $168,290 for the year ended December 31, 1996, a decrease of
$90,542, or 53.8%. Other service fees revenue is primarily derived from minor
transactions with currently existing WAM!NET Service customers which includes
consulting services and hardware sales. The decrease was primarily due to the
expiration of a contractual consulting relationship that the Company had in
place with a customer during 1996.
 
 Operating Expenses
   
  Network communications fees for the year ended December 31, 1997 were
$7,363,667, compared to $816,403 for the year ended December 31, 1996, an
increase of $6,547,264, or 802.0%. Network operations expense for the year
ended December 31, 1997 was $7,477,753, compared to $1,108,807 for the year
ended December 31, 1996, an increase of $6,368,946, or 574.4%. These increases
were primarily due to the 1,375.8% increase in customers that subscribed to
the WAM!NET Service during 1997.

  Sales and marketing expense for the year ended December 31, 1997 was
$9,207,486, compared to $2,052,860 for the year ended December 31, 1996, an
increase of $7,154,626, or 348.5%. This increase primarily resulted from costs
associated with building the Company's direct sales force and marketing
department, and higher outside advertising agency and trade show expenditures.
 
  General and administrative expense for the year ended December 31, 1997 was
$4,320,128, compared to $2,609,879 for the year ended December 31, 1996, an
increase of $1,710,249, or 65.5%. General and administrative expense increased
during 1997 as operational support requirements intensified due to the rapid
expansion of the Company's services and corporate facilities.
 
  Depreciation and amortization for the year ended December 31, 1997 was
$2,668,177, compared to $447,233 for the year ended December 31, 1996, an
increase of $2,220,944, or 496.6%. As a percentage of total revenue,
depreciation and amortization was 171.6% in 1997 compared to 160.5% in 1996.
This increase is primarily due to an increase in the installed customer
premise and communications backbone equipment as a result of the increase in
the number of customers.
 
  Interest expense for the year ended December 31, 1997 was $4,355,676,
compared to $903,443 for the year ended December 31, 1996, an increase of
$3,452,233, or 382.1%. The increase was primarily due to the Company's
financing of its 1997 operations through the issuance of various debt
instruments, including $24 million of long term subordinated notes to
WorldCom, $18.8 million in borrowings from the Revolving Credit Facility and
$9.6 million of equipment financing.
 
 Income Taxes
   
  For the year ended December 31, 1997, the Company experienced net losses of
$33,636,000 and paid no income taxes. These losses are available to offset
future taxable income through the year 2013 and are subject to the limitations
of Section 382 of the Internal Revenue Code of 1986, as amended. These
limitations may result in expiration of net operating loss carryforwards
before they can be utilized.     
 
YEAR ENDED DECEMBER 31, 1996 COMPARED WITH YEAR ENDED DECEMBER 31, 1995
 
 Revenue
 
  Revenue for the year ended December 31, 1996 was $110,424, compared to
$20,480 for the year ended December 31, 1995, an increase of $89,944 or
439.2%. This was due primarily to the increase in the number of customers
using the WAM!NET Service. On December 31, 1995, the Company serviced
approximately 6 installed customer sites and on December 31, 1996 serviced 33
installed customer sites.
 
  Other service fees revenue for the year ended December 31, 1996 was
$168,290, compared to $159,851 for the year ended December 31, 1995, an
increase of $8,439 or 5.3%. Other service fees revenue is primarily derived
from minor transactions with currently existing WAM!NET Service customers
which includes consulting services and hardware sales.
 
 Operating Expenses
 
  Network communication fees for the year ended December 31, 1996 were
$816,403, compared to $46,267 for the year ended December 31, 1995, an
increase of $770,136, or 1,664.5%. Network operations expense for the year
ended December 31, 1996 was $1,108,807, compared to $539,003 for the year
ended December 31, 1995, an increase of $569,804, or 105.7%. These increases
were primarily due to the 450.0% increase in the number of WAM!NET Service
customers during 1996 and the installation of certain Distribution Hubs
throughout the United States.
 
  Sales and marketing expense for the year ended December 31, 1996 was
$2,052,860, compared to $93,832 for the year ended December 31, 1995, an
increase of $1,959,028, or 2,087.8%. This increase, to a large extent,
 
                                      41
<PAGE>
 
represents the significant costs associated with building and supporting a
dedicated direct sales force and product marketing organization.
 
  General and administrative expense for the year ended December 31, 1996 was
$2,609,879, compared to $727,434 for the year ended December 31, 1995, an
increase of $1,882,445, or 258.8%. General and administrative expense
increased during 1996 as operational support requirements intensified due to
the expansion of the Company's services and corporate facilities.
 
  Depreciation and amortization for the year ended December 31, 1996 was
$447,233, compared to $30,677 for the year ended December 31, 1995, an
increase of $416,556, or 1,357.9%. As a percentage of gross revenue,
depreciation and amortization was 160.5% in 1996 compared to 17.0% in 1995.
This increase is primarily due to the intense expansion of the WAM!NET Network
during 1996 and the corresponding requirement for both customer premise and
communications backbone equipment.
 
  The Company's results of operations for the years ended December 31, 1996
and 1997 are not necessarily indicative of future periods. The Company's
principal focus during such time was the selection and hiring of personnel for
sales, marketing operations, customer service, development, network
infrastructure implementation and maintenance necessary to conduct its
activities, and the development and release of various proprietary WAM!NET
Service products. The Company expects that future results will reflect the
commercial operations of the WAM!NET Service.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  From inception through March 31, 1998, the Company has derived substantially
all of its operating capital from the issuance of short- and long-term debt
instruments. At March 31, 1998, the Company had a total of approximately
$143.4 million in long-term debt, of which approximately $2.7 million becomes
payable during 1998.
   
  The Company's source of liquidity since inception has primarily come from
the issuance of debt and equity instruments and from credit facilities and
other borrowings. The Company has received approximately $154.7 million net
cash proceeds from the issuance of long- and short-term debt and
collateralized equipment financing. An additional $1.8 million of net cash
proceeds has been received from the sale of equity securities. The Company has
utilized these proceeds by investing $31.7 million into its global WAM!NET
Network and investing $20.3 million to acquire 4-Sight. Since inception the
Company has also expended $40.7 million to fund its operating activities. To
date the Company has not generated cash from operating activities and remains
dependent upon its ability to generate operating capital for its global
expansion from credit facilities or other borrowings, or the issuance of
additional long- and short-term debt and equity instruments.     
   
  During September of 1997, the Company established the Revolving Credit
Facility, the proceeds of which are being used by the Company to fund its
operations and purchase WAM!NET Network equipment. The maximum amount that can
be borrowed under the Revolving Credit Facility is $25.0 million. The
Revolving Credit Facility was established under an agreement with WorldCom, by
which WorldCom guaranteed the Company's obligations under the Revolving Credit
Facility. At March, 1998, the Company had $0 borrowed under the Revolving
Credit Facility. Interest and principal on the Revolving Credit Facility
become payable in July 1999. Borrowings by the Company under the Revolving
Credit Facility require the prior consent of WorldCom.     
   
  In December 1997, the Company acquired the outstanding common stock of
FreeMail, Inc. ("FreeMail"). In connection with the acquisition the Company
issued 125,000 shares of Common Stock, with a fair value of approximately
$488,000, as consideration. The Company is also obligated to pay the former
shareholders of FreeMail as additional contingent consideration on a quarterly
basis amounts equal to five percent of the gross collected revenue derived by
the Company from certain identified FreeMail products; however, the total
amounts of the quarterly payments shall not exceed $3,012,500. As of March 31,
1998, the Company did not record a liability relating to the FreeMail revenue
since no revenue was collected.     
 
                                      42
<PAGE>
 
  On March 5, 1998, the Company consummated the Initial Offering, and received
net proceeds therefrom of approximately $120.6 million. Cash interest does not
accrue nor is payable on the Notes prior to March 1, 2002. Thereafter, cash
interest on the Notes will accrue at a rate of 13 1/4% per annum (calculated
on a semi-annual bond equivalent basis) and will be payable semi-annually in
arrears on March 1 and September 1 of each year, commencing September 1, 2002.
The Company used the proceeds of the Initial Offering as follows: (i) $20.0
million to pay the cash portion of the 4-Sight Acquisition, (ii) approximately
$25.0 million to repay the borrowings under the Revolving Credit Facility and
(iii) the balance to be used further the Company's business development and
expansion strategy, to enhance the WAM!NET Service infrastructure and develop
additional value-added features and services, to optimize marketing, sales and
customer support and service capabilities, and for working capital and other
general corporate purposes.
   
  The Company intends to pursue one or more financings in 1998, totalling
approximately $100.0 million, for which it has received indications of
interest from certain financial institutions. The Company believes that the
net proceeds of the Initial Offering and such financings together with
expected cash from operations will be sufficient to finance the Company's
operations through September 30, 1999. This includes the purchase and
installation of all necessary WAM!NET Network and WAM!BASE equipment required
for both national and international operations, marketing and sales
activities, continued development of enhancements to the WAM!NET Service and
service of its debt obligations. The Company believes that the net proceeds
from the Initial Offering together with expected cash from operations will be
sufficient to finance the Company's operations through March 31, 1999. The
Company intends to invest an additional $30.0 million in its global WAM!NET
Network infrastructure by December 31, 1998 and an additional $45.0 million in
its global WAM!NET Network infrastructure by December 31, 1999. These
investments are necessitated by the need to grow the global communications
network to provide contracted services to the Company's rapidly expanding
customer base. The Company's inability to secure an additional $100.0 million
in funding by March 31, 1999 would adversely affect its ability to expand the
WAM!NET Network during 1999 to meet rapidly growing demand for global network
services. If the Company is unable to obtain additional financing when needed,
it may be required to significantly scale back expansion plans and, depending
upon cash flow from its existing business, reduce the scope of its plans and
operations.     
   
  Pursuant to an agreement with WorldCom, if the Company is not publicly held
by 2000, under certain circumstances and subject to certain conditions, the
Company may be required to buy and WorldCom may be required to sell, the
WorldCom Securities (as defined herein) pursuant to a tender offer and pricing
methodology described herein under "Certain Transactions and Relationships."
If the Company fails to timely pay the purchase price for the WorldCom
Securities, WorldCom will be relieved of all obligations to sell such
securities to the Company, the Company will have no right to cause WorldCom to
sell such securities and the Company will not be obligated to pay the purchase
price for such securities. See "Certain Transactions and Relationships."     
   
  During 1997 the Company, on a pro forma basis after giving effect to the 4-
Sight Acquisition, received less than 5% of its total revenue from sales and
operations in Asian countries. As a result, the Company had limited exposure
to the particular risks attendant to doing business in Asia and did not
experience any material adverse effects from the Asian economic crisis;
however, the Company presently intends to expand its operations in that
region. The Company is currently unable to determine the effect, if any, that
recent economic downturns in Asia, particularly Japan, will have on the
Company's future business, operating results or liquidity, although the
Company intends to exercise prudence and sound business judgment prior to
making any future investments in Asia.     
   
  Currently, the Company does not employ currency hedging strategies to reduce
the risks associated with the fluctuation of foreign currency exchange rates.
The Company presently denominates all of its contracts in U.S. dollars. 4-
Sight denominates all of its contracts in pounds sterling except for its U.S.
sales, which are denominated in U.S. dollars, or its German sales, which are
denominated in German marks. The Company is unable to determine what effect,
if any, the adoption and use of the euro, the single European currency to be
introduced in January of 1999, will have on the Company's business, operating
results, liquidity and financial condition.

RECENTLY ISSUED ACCOUNTING STANDARDS     
   
  In June 1997, the FASB issued Statement 130, "Reporting Comprehensive
Income."  Statement 130 is effective for financial statements for fiscal years
beginning after December 15, 1997. This standard defines comprehensive income
as the changes in equity of an entity except those resulting from shareholder
transactions. All components of comprehensive income are required to be
reported in a new financial statement. The adoption of Statement 130 did not
have a material effect on the Company's financial statements.     
   
  In June 1997, the FASB also issued Statement 131, "Disclosures about
Segments of an Enterprise and Related Information." Statement 131 is effective
for financial statements for periods beginning after December 31, 1997.
Statement 131 establishes standards for disclosures about operating segments,
products and services, geographic areas and major customers. The adoption of
Statement 131 did not have a material effect on the Company's financial
statements.     
   
  In October 1997, the AICPA issued Statement of Position 97-2, "Software
Revenue Recognition" ("SOP 97-2"), which superseded Statement of Position 91-1
for periods beginning after December 15, 1997. The adoption of SOP 97-2 did
not have a material effect on the timing of the Company's revenue recognition
or cause changes to its revenue recognition policies.

                                   BUSINESS
 
OVERVIEW
 
  WAM!NET provides a managed, high speed digital data delivery network
service, the WAM!NET Service, that integrates the Company's industry-specific
work flow applications with commercially available computer and telephony
technologies. The Company, an affiliate of WorldCom, offers an Industry Smart
service designed to provide its subscribers with a turn-key single source
solution for the rapid, secure, accurate and reliable transportation and
management of information, with a simple "pay by the megabyte" pricing plan
requiring no capital investment. The WAM!NET Service provides seamless digital
connectivity among "communities of interest," drawing together customers and
trading partners which have collaborative work flows. The Company has
developed advanced WAM!NET Service applications, including an on-line digital
job tracking and billing system, CIS, an application enabling remote proofing,
WAM!PROOF, and a remote data archiving, retrieval and distribution system
WAM!BASE. WAM!PROOF was commercially released in the second quarter of 1998
and WAM!BASE is scheduled for commercial release in the second half of 1998.
 
  The Company has initially capitalized on the growing need for managed
digital data delivery services in the printing, publishing, advertising, pre-
press, corporate communication and graphic arts industries (collectively,
"Graphic Arts"). The Company believes that the WAM!NET Service is achieving
wide acceptance among leading firms within the Graphic Arts community of
interest, which in turn encourages those with whom such firms share digital
information to subscribe to the WAM!NET Service. Since it commercially
released and commenced marketing of the WAM!NET Service in March 1996, the
Company has established a subscriber base of more than 1,500 customer
locations, including Time, Donnelley, Disney, J.C. Penney, Fox Broadcasting
and Macy's. In October 1997, the WAM!NET Service received the Graphic Arts
Technical Foundation (an independent trade association) award for the product
or service that will most likely change the manner in which the Graphic Arts
industry conducts business.
 
MARKET OPPORTUNITY
   
  The Company believes that the increasing digitalization of work product and
work flow in data intensive and time sensitive industries is driving demand
for managed, secure and reliable electronic data transportation and archiving
services. Based on information derived from independent studies, the Company
believes that the Graphic Arts industry will spend approximately $10.0 billion
between 1998 and 2000 on the digitalization of its production and printing
process, including the introduction by commercial printers of CTP technology,
which facilitates a fully digital work product. Despite this movement toward
the digital creation, storage and outputting of data, the lack of reliable,
cost effective electronic transport mechanisms has resulted in many companies
continuing to use overland or air courier services to deliver magnetic tape or
optical disk copies of data to others who require access to such data. This
non-digital step results in a method of transporting data which can be
inefficient, significantly lengthening production cycle time and leading to
possible errors. The Company believes the potential market for managed digital
data transportation and asset storage services is $4.3 billion and $2.3
billion, respectively, in the Graphic Arts industry alone.     
   
  The Company believes that existing electronic means for transporting large
digital data files have proven to be ineffective and/or prohibitively
expensive for most companies. Large files may take up to several days to
transport using the Internet or the fastest standard telephone modems (56,000
bps) and may lose significant quality in transmission. The use of the Internet
and standard telephone modems can also lead to other significant
disadvantages, most notably high telephone usage charges and a lack of
security, accountability and reliability of transmission. Other non-dedicated
technologies such as point to point telephone lines offer more speed than the
Internet, which is not managed, or a standard telephone modem, but at a
significantly higher cost. Such technologies may also lead to data degradation
and integration obstacles. Large data files can be transported reliably in
minutes over dedicated point to point telephone lines (such as DS1 and DS3);
however, the substantial equipment necessary at each dedicated connecting
point and the sizable costs of leasing a dedicated point to point telephone
line makes this means of transport uneconomical for most companies
transporting large data files.

COMPETITIVE ADVANTAGES
 
  The Company believes it is uniquely positioned to meet the growing need for
a cost-effective and reliable means of electronically transporting, storing
and retrieving digital data due to the following competitive advantages:
 
 .  Purpose-Built, Industry Smart Network. The WAM!NET Service operates via a
   nationwide network that integrates the Company's proprietary, value-added
   Industry Smart applications with a purpose-built network of Company owned
   Distribution Hubs interconnected redundantly with high-bandwidth leased
   telephone circuits. The Company currently maintains 23 Distribution Hubs,
   located in major United States and Canadian cities, London, England and
   Paris, France. The Company operates two NOCs in Minneapolis and Las Vegas
   through which it monitors all data transmission on a 24 hour a day, 7 day a
   week basis. The Company believes the WAM!NET Service offers reliable and
   secure data transmissions with no degradation in quality and guaranteed
   delivery and throughput.
 
 .  Single Source, Turn-Key Service Solution. The Company provides each
   subscriber with all of the hardware, software, transmission facilities and
   management services necessary to use the WAM!NET Service. Installation of
   the service, which is performed on behalf of the Company by national
   service providers, consists of connecting the customer to the nearest
   Distribution Hub through a Company-owned NAD and an appropriate
   communications link (such as T1, ISDN, frame relay, ADSL or other suitable
   facility) matched to the customer's transfer speed and throughput
   requirements. The WAM!NET Service is designed for ease of use, with a point
   and click e-mail type interface and a simple "pay by the megabyte" pricing
   model. The Company's strategy is to offer customers the WAM!NET Service at
   rates competitive with overland and air courier services furnished on an
   annual or multi-year subscription basis. There is no up-front capital
   investment by the customer, who is charged based on a minimum monthly usage
   fee and volume of data sent per transaction.
 
 .  Industry Smart Applications. The Company collaborates with leading
   participants in its target markets and designs applications addressing
   industry-specific work product and work flow requirements. These Industry
   Smart applications combined with the guaranteed delivery and throughput of
   the WAM!NET Service allow work partners in distant geographic locations to
   collaborate digitally in real time. The WAM!PROOF application will allow
   customers to directly output across the WAM!NET Network to proofing devices
   in remote locations, thereby eliminating the need to deliver physical
   proofs by overnight courier. The WAM!BASE application will provide a
   collaborative digital asset management service that can eliminate the need
   for redundant archives and shrink work cycle time by providing more
   immediate access to desired data files.
 
 .  Customer Support and CIS. The Company has implemented extensive customer
   service functions, including customer support technicians who are available
   24 hours a day, are trained extensively in the Company's service offerings
   and who understand the industry-specific work flow of the Company's
   customers. CIS allows customers to view data files, verify account
   information and check the status of transactions on-line, as well as to log
   help requests. The Company provides its customers itemized information
   regarding the size, cost, and destination of each "shipment" that may be
   electronically imported directly into the customer's own accounting system,
   which facilitates capturing of project-specific costs and billing of
   services on a job-by-job basis.
 
 .  First to Market Advantage. By being the first to market a managed, high
   speed digital data delivery network with Industry Smart applications, the
   Company believes it is becoming the industry standard in the Graphic Arts
   industry and is positioned to become the industry standard in its other
   target industries. The Company has found that industry leaders such as Time
   and Donnelley (early WAM!NET Service customers) actively encourage their
   work flow partners to subscribe to the WAM!NET Service to increase work
   flow efficiencies. Potential entrants into the managed digital data
   delivery field would need to deploy a nationwide, purpose-built network
   integrated with customized value-added applications, and simultaneously
   convert industry leaders and their work flow partners, more than 900 of
   whom have contracted with the Company for the WAM!NET Service at more than
   1,500 locations. Customers currently subscribing to the WAM!NET Service
   include 11 of the 20 largest publishers, 9 of the 20 largest printers,
 
                                      46
<PAGE>
 
   16 of the 20 largest advertising agencies, and 10 of the 20 largest pre-
   press-graphic arts agencies in the United States, as well as the corporate
   communications and advertising departments of many United States
   corporations.
 
 .  Strategic Relationship with WorldCom. The Company has entered into a
   strategic alliance with WorldCom which includes equity and debt investments
   and operating loan guarantees totaling approximately $50.0 million.
   WorldCom is currently entitled to designate a majority of the Board of
   Directors of the Company and, through its ownership of convertible debt and
   warrants, has the right to acquire a majority of the Common Stock of the
   Company. WorldCom also provides telecommunication and other services to the
   Company on a non-exclusive basis. The Company anticipates that its
   relationship with WorldCom will enable it to access the worldwide
   infrastructure, sales and marketing work force, telephony technologies,
   high bandwidth carrier service and other services of WorldCom and its
   affiliates, including UUNet.
 
BUSINESS STRATEGY
 
  The Company's objective is to become the leading provider of enhanced,
managed digital data delivery and archiving services to industries comprised
of interdependent participants requiring industry specific, high speed digital
connectivity. WAM!NET's strategy to achieve this objective and to build a
long-term sustainable competitive advantage is to:
 
 .  Increase its Customer Base to Create Critical Mass. The Company's sales and
   marketing strategy has been designed to rapidly penetrate its initial
   target market, the Graphic Arts industry. Elements of this strategy
   include: (i) creating the WAM!NET Service as a turn-key, single source
   service solution; (ii) implementing an easy to understand "pay by the
   megabyte" pricing model (which eliminates the need for any capital
   investment by customers); (iii) designing aggressive advertising, trade
   show, event marketing and direct selling to drive trials, including
   introductory risk-free product evaluations for industry leaders; (iv)
   building a direct sales force to target leading industry participants who,
   in turn, encourage their work flow partners to subscribe to the WAM!NET
   Service; and (v) implementing programs in which large receivers of data
   (e.g., printers) promote and market the WAM!NET Service, along with the
   WAM!NET direct sales force, to customers and work flow partners. The
   Company believes that the customer benefits of the WAM!NET Service will
   increase exponentially as the total number of WAM!NET Service subscribers
   increases.
 
 .  Apply Industry Smart Network Model to Other Industries. The Company
   believes that the WAM!NET Industry Smart network model can provide the
   benefits and advantages it offers the Graphic Arts industry to other
   industries with similar data transportation, storage and retrieval
   requirements. Some of the Company's customers that are in the entertainment
   industry, such as Fox Broadcasting and Disney, currently subscribe to the
   WAM!NET Service for their Graphic Arts-related needs. The Company is
   presently developing Industry Smart applications suitable to the
   entertainment industry and is developing corresponding marketing and sales
   strategies. The Company is also collaborating with industry leaders in the
   medical imaging industry to develop and implement Industry Smart
   applications in connection with marketing to that industry.
 
 .  Drive Utilization Through Value-Added Services and Volume Discounts. The
   Company incorporates, develops and implements value-added Industry Smart
   applications for customers, such as CIS, WAM!PROOF and WAM!BASE, which the
   Company believes will provide significant benefits to its customers and
   stimulate increased usage of the WAM!NET Service. The Company also offers
   volume discounts and a variety of promotional programs for industry leaders
   to induce customers to send increasingly large volumes of data traffic
   across the WAM!NET Network.
 
 .  Expand and Enhance Infrastructure and Develop Worldwide Capabilities. The
   Company intends to invest in resources and systems to ensure that the
   WAM!NET Network's operating infrastructure and support services provide
   optimal digital connectivity to its subscribers in a guaranteed performance
   and competitive rate environment. The Company is currently preparing to
   expand into parts of Europe and Asia for the purpose of providing its
   customers with desired international connectivity. The Company expects to
   expand the WAM!NET Network into approximately 10 countries by the end of
   1998, and will initially locate
 
                                      47
<PAGE>
 
   additional Distribution Hubs in London, Frankfurt, Paris, Amsterdam, Milan,
   Tokyo, Hong Kong, and Sydney. The London and Paris Distribution Hubs were
   recently installed and the Company is currently in the process of
   installing a Distribution Hub in Amsterdam. During 1998, the Company
   expects to further develop its international service infrastructure by
   providing installation and customer support via third parties, developing
   local sales and distribution relationships and may establish additional
   Distribution Hubs and regional NOCs in selected countries. The Company's
   acquisition of 4-Sight will permit subscribers, including 4-Sight's 30,000
   customers in 44 countries, to gain remote access to the WAM!NET Network
   through transmission software being developed by 4-Sight. The Company may
   also establish its international presence through other acquisitions, joint
   ventures or other similar business transactions.
 
 .  Reduce Costs and Improve Operating Margins. The Company seeks to reduce
   costs and improve operating margins by (i) spreading the cost of installing
   and operating the WAM!NET Network over a large base of customers; (ii)
   designing the network to use more expensive hub equipment in a few national
   and regional operational centers and less expensive equipment at each
   customer site; (iii) deploying cost-reduced NADs for less volume intense
   customers; (iv) pursuing programs to reduce the costs of capital equipment,
   including obtaining mass purchasing discounts for network infrastructure
   and customer premise equipment; (v) utilizing network management tools to
   optimize existing and planned network capacity as volume increases and
   traffic patterns begin to emerge; (vi) deploying new, lower-cost last mile
   local loop technologies to connect customer sites to Distribution Hubs,
   including wireless technologies and remote dial-up capabilities; and (vii)
   deriving other incremental revenue from value-added services such as
   WAM!BASE, which can be delivered over the existing WAM!NET Network
   infrastructure. The Company also believes its operating margins will
   improve as a result of anticipated cost reductions associated with
   increasing competition in both the local and long distance markets.
 
TARGET MARKET OVERVIEW
 
  The WAM!NET Service has been designed to support a community of interest
among interdependent participants in time sensitive and data intensive
industries with highly collaborative work flows. The Company is currently
actively marketing its services to the Graphic Arts industry, and is preparing
to market the WAM!NET Service to other communities of interest with similar
data transportation and archiving needs as those found in the Graphic Arts
industry, including the entertainment and medical imaging industries. The
Company believes it can apply its business strategy to these other industries
by capitalizing on the network, operations, service, application engineering
and sales/marketing infrastructure already developed by the Company and by
developing and offering "Industry Smart" applications that are tailored to the
work flow requirements of those industries.
   
  Graphic Arts. The Graphic Arts industry is comprised of printers, pre-press
production firms, advertising agencies, publishing firms, graphic artists and
list management firms who design, prepare and produce printed materials. Based
on industry information and research performed for the Company, the Company
estimates the total potential size of the managed data delivery service and
the digital asset storage markets for the Graphic Arts industry in the United
States to be $4.3 billion and $2.3 billion, respectively. The Company's
estimate of the number of potential sites in key segments of the Graphic Arts
industry is outlined below, based on information contained in industry
research reports.

  The materials created and printed by the Graphic Arts industry include
books, magazines, newspapers, catalogues, circular advertisements, billboard
advertisements, marketing materials, brochures, packaging and multi-media
materials. According to industry data, approximately 50% of content in the
Graphic Arts industry currently created in a digital format using specialized
software applications such as Adobe PhotoShop and Quark Express, and by the
year 2000, more than 64% of the Graphic Arts industry is expected to be using
digital page/imaging software. File assembly and printing preparation
activities are also becoming digital with the increasing use of digital
scanners and cameras. Analog images, including photographs, can now be easily
scanned and digitally incorporated into the production process. Additionally,
adoption of CTP technologies by large- and medium-sized printers facilitates a
fully digital work flow throughout the entire creation and printing process.
    
  The digitalization of the printing process has resulted in the need for
higher bandwidth connectivity to move data intensive printing jobs through the
print production process and storage solutions which provide asset management
capabilities and collaborative access to the stored digital assets. Today, the
majority of work files are stored on magnetic or optical disks and transported
via local or overnight couriers, such as Federal Express and United Parcel
Service. The Company anticipates that large portions of data will increasingly
be delivered via digital networks, driven primarily by the need to compress
time schedules and reduce production costs. The Company expects that once
market leaders and other influential participants in these industries become
significant users of managed data delivery services, other industry
participants will follow in an effort to remain competitive.
   
  The Company believes it is positioned to take advantage of the following
factors, identified by industry research reports, which indicate that between
1996 and the year 2000: (i) the percentage of print jobs transferred across
networks will quadruple, representing over 40% of all print jobs and two
thirds of print job revenue; (ii) more than 50% of all publishing work flow
and more than 60% of all creative services workflow will be conducted almost
entirely over networks; (iii) businesses with the equivalent of TI wide area
connectivity will increase 5 times; (iv) manufacturers will integrate CTP
equipment creating a total digital pre-press work flow; (v) high resolution
digital cameras will be affordable for most Graphic Arts users; and (vi) most
medium to large printers and pre-press firms will offer digital content
management services to support re-purposing of digital data into other
products.     
 
  Entertainment Industry. The entertainment industry, which is closely related
to the Graphic Arts industry, provides another potential community of interest
for the expansion of the WAM!NET Service. This industry consists of many
subsectors, including feature films, broadcast, cable and satellite video,
high-definition television, home video, video games and video applications on
the Internet. An adjunct market to the entertainment industry is the distance
learning market, which includes corporate (training, marketing and
communications) and educational distance learning. Each of these subsectors is
moving away from traditional analog media, such as film, photographs and other
physical media expression, and toward digital media. Digital tools previously
available only to large media customers (such as television networks and major
film studios) are now widely available to the entire industry. The Company
believes the WAM!NET Service will be affordable to a wide spectrum of
customers, including the independent contractor/artist and small, medium or
large production and post-production studios, as well as to global media
conglomerates.
 
  In contrast to the Graphic Arts industry, however, which involves the
creation of static or still imagery, the entertainment industry principally
produces motion imagery coupled with digital audio. As a comparison, a 30-
second television advertisement is comprised of approximately 500 times the
amount of digital data found in the
 
                                      49
<PAGE>
 
typical full page magazine advertisement. The Company believes the WAM!NET
Network is sufficiently scalable and robust to accommodate the high-speed data
transfer rates necessary to transport motion imaging in the entertainment
industry.
 
  The Company's strategy is to enable remote collaboration throughout all
phases of production, including pre-production (planning, CAD and
previsualization), to production (filming and "video dailies"), post
production (picture and sound editing and special effects creation) and
eventually distribution services. The Company believes that the WAM!NET
Service, by speeding up the iterative cycle of collaborative production, will
provide significant creative advantages and cost savings to existing
production processes.
 
  Medical Imaging. The emergence of digital medicine disciplines has created
another community of interest that may have promising applications for the
WAM!NET Service. The increasing availability of advanced computer technology
combined with continued pressures to contain health care costs is resulting in
significant portions of the medical imaging work flow being completely
digitized, including output from medical scanning equipment such as Computed
Tomography ("CT") and Magnetic Resonance Imaging ("MRI") devices. These
devices capture and display patient data in digital formats, generating data
files often in excess of 35 megabytes per file.
   
  The Company has identified multiple steps in the medical imaging work flow
process which may effectively be addressed by the WAM!NET Service. For
example, radiologists and other healthcare professionals who examine the
output generated by CT and MRI devices are often located in facilities
separate from the facilities where the digital images are created.
Furthermore, the increasing prominence of health maintenance organizations and
other provider alliances, where member patients can go to any facility within
the provider's network, may necessitate the increased ability to retrieve and
transport data, including medical imaging data, between physically separate
facilities. Currently, most files are either printed to film or copied to
optical disks and then physically transported via courier services between
facilities. In cases where digital images are printed to film, healthcare
professionals lose the ability to do real time reads of the images. Current
methods of storing medical images also present file transportation and storage
problems. Analog files need to be manually located, copied and couriered to
the healthcare professional for examination. It is estimated that 10%-25% of
images stored in a (non-digital) film format are misplaced after they are
stored. Digital file storage is emerging as an option, but optical disks still
need to be located, copied and then transported to remote sites.     
 
  As a result, real-time remote imaging and archiving among hospitals is
gaining momentum and may create efficiencies by allowing radiologists to
collaborate more effectively. As documented in the January 1998 Journal of
Diagnostic Imaging, Hammersmith Hospital in London, England, found that the
change from hardcopy to digital archiving reduced staffing requirements by 8
positions, saved an estimated $0.7 million per year, and increased workload by
4,500 exams per year without adding additional radiologists. The Company
believes the industry will need to eliminate multiple archives to adopt full
digital implementation and provide affordable long-term on-line storage.
   
  The Company believes that medical service providers, particularly those of
substantial size or that span a number of separate facilities, have
significant medical imaging requirements. It is estimated that the current
medical imaging storage costs of medical institutions in the United States is
$7.5 billion per year.     
 
4-SIGHT BUSINESS
 
  On March 13, 1998, the Company consummated the purchase of the entire share
capital of 4-Sight, a private limited company incorporated under the laws of
England and Wales, for $20.0 million in cash and up to 3,250,000 shares of the
Company's Common Stock. 4-Sight is a provider of data transmission software
and related products and applications targeted to the Graphic Arts industry,
primarily utilizing ISDN lines, with particular emphasis on European, Asian
and North American markets and is engaged primarily in software development
and distribution. The software user is generally responsible for all software
and hardware installation, procuring an ISDN telephony connection and
verifying the integrity of their files being sent over a
 
                                      50
<PAGE>
 
public network infrastructure. The Company believes that there are potential
synergies in coupling 4-Sight's data transportation software with WAM!NET's
managed, network infrastructure and that the 4-Sight Acquisition will enable
the Company to achieve broader market coverage in the Graphic Arts market by
combining 4-Sights international presence and penetration of the lower volume
user market with the Company's domestic presence and penetration of the higher
volume user market. At December 31, 1997, 4-Sight had a customer base of more
than 30,000 customer locations, including 3,000 sites in the United States.
 
  4-Sight's current set of products has been designed to work with public ISDN
telephony infrastructures used widely in Europe and Japan and to a lesser
extent in the United States. 4-Sight does not provide managed network services
to deliver files. 4-Sight employs developers to design and distributes its
software products on a global basis through resellers. 4-Sight currently has 4
offices located in the United Kingdom, the United States and Germany. In
addition, 4-Sight has formal sales agreements with resellers who distribute 4-
Sight's products in 19 countries. 4-Sight's software products are installed at
over 12,000 sites in the United Kingdom, where 4-Sight estimates it has a 90%
market share in the Graphic Arts market segment. Key users of 4-Sight software
in the United States include Xerox Corporation ("Xerox"), Ogilvy & Mather
Worldwide, Inc., McCann-Erickson Worldwide and National Geographic Society.
 
  4-Sight Product Description. 4-Sight engages solely in software development
and distribution and does not provide data transportation services with any of
its products. The software user is responsible for all software and hardware
installation, procuring an ISDN connection and verifying the integrity of
their files being sent over a public network infrastructure. iSDN Manager is
4-Sight's flagship product for ISDN file transfer. The current release, iSDN
Manager (4), comes in a MacIntosh ("Mac") version and a PC version, which
supports Windows 95 and Windows NT platforms. iSDN Manager supports cross
platform file exchanges between Mac and PC desktops and is compatible with
over 75,000 ISDN systems world-wide. iSDN Manager supports different ISDN
cards with various throughput capabilities. The majority of software sales are
bundled with an ISDN card. The software functions like an e-mail application,
where the user selects one or more sites to which files are to be sent from an
address book, attaches files and then transmits the data via the public, dial-
up ISDN network to other 4-Sight compatible sites. In addition, 4-Sight offers
a less powerful version of iSDN Manager and other products and services,
including a version of iSDN Manager that is customized for the newspaper
advertisement delivery market and desktop fax software.
 
  Key Benefits from the 4-Sight Acquisition. The Company expects to realize
multiple benefits from the 4-Sight Acquisition including:
 
  Providing Additional Network Access: 4-Sight's current software applications
can be modified to allow access to the WAM!NET Network. New versions of 4-
Sight software can be introduced which are WAM!NET Service compatible and can
be used to send to and receive data from other WAM!NET and 4-Sight sites. The
Company believes this will significantly improve its ability to attract and
retain customers at the lower end of the market segment where ISDN lines are
most common. The Company expects that the 4-Sight Acquisition will enable the
Company to achieve broader market coverage in the Graphic Arts market by
combining 4-Sight's international presence and penetration of the lower volume
user market with the Company's domestic presence and penetration of the higher
volume user market. In addition, many of the Company's current customers have
work flow partners who use 4-Sight's software. Modifying 4-Sight technology
will allow 4-Sight customers to transmit data to WAM!NET Service customers
with whom they require periodic data exchange and thereby increase traffic
over the WAM!NET Network.
 
  Facilitating 4-Sight Customer Upgrades: 4-Sight software upgrades that are
WAM!NET Service compatible can be marketed to existing 4-Sight customers and
bundled with WAM!NET Service contracts. In addition, the Company could
potentially re-provision local loop ISDN lines for the current 4-Sight
customer base or upgrade higher traffic sites to NADs.
 
  Accelerating International Expansion: 4-Sight has already invested in
developing distribution channels in the United Kingdom, Germany, Benelux,
Scandinavia and Japan and has plans to expand distribution capabilities
 
                                      51
<PAGE>
 
in France and other Asian markets. The 4-Sight investment is represented by
the formal working relationships 4-Sight has developed with dealers, by the
people it employs to manage dealer relationships in these international
markets and by the working knowledge 4-Sight employees have developed
regarding unique business practices in these international markets. The
Company believes that it can utilize 4-Sight's existing distribution
infrastructure and investment to bundle the WAM!NET Services with new versions
of 4-Sight's transmission software. By utilizing 4-Sight's infrastructure and
investment, the Company also believes that it can reduce the time that it will
take to enter certain international markets by nine to twelve months.
 
  Accelerate Development Activities: 4-Sight has invested significant
resources to build software development competencies in data transmission user
applications. In addition, 4-Sight has developed capabilities to localize its
software applications for use in specific international markets including the
French, German, Benelux and Japanese markets. These capabilities may augment
the Company's development staff and help increase application development
staffing expertise.
 
PRODUCTS AND SERVICES
 
  The WAM!NET Service. To send or receive a data file over the WAM!NET
Network, a customer uses a proprietary software program designed and furnished
by the Company. The WAM!NET Service appears as a icon on the customer's
desktop, like a multi-layered e-mail or fax application. Clients can use the
application to manage an address book of WAM!NET users with whom they send and
receive packages of files and to set application default parameters. To send a
package, the user "highlights" and "drags" a file to the appropriate address
"hot tile" which appears across the top of the user interface. Once a file is
dropped onto an address tile, a packing slip is automatically opened and the
user is prompted to fill out basic packing slip information. Additional files
can be added to the package to be included in the transmission. Similarly,
additional sites can be identified for simultaneous package delivery. The user
then selects the send button and the package is automatically delivered to the
user's NAD for processing, coding and routing. Once a package has been
delivered to a NAD, the package will be transported regardless of whether the
sending or receiving computer is operating. If the destination computer is
unavailable, the package will be held for delivery until the destination
computer becomes available to receive the file. Unlike a dial-up network,
where both computers need to be on and available at either end or there will
be a busy signal, the WAM!NET Service's store and forward function holds the
file in transit until the file can be delivered. To receive a package,
customers are prompted on screen to view packages that have been received by
their NAD. Files can be transferred from the NAD to the client's LAN either by
dragging and dropping files from the NAD icon to the local network or by using
a file retrieval menu.
 
  Each transaction over the WAM!NET Service is tracked and accounted for as an
individual "shipment" of data. On a monthly basis, the Company furnishes its
customers with an invoice summarizing the customer's WAM!NET Service use and
charges. If requested by a customer, the Company will also deliver to such
customer an electronic data file over the WAM!NET Service that contains
itemized information regarding the size, cost and destination of each shipment
as well as information regarding other services used by the customer. This
data file may be imported directly into the customer's own accounting system,
providing what the Company believes to be a valuable service for customers who
need to capture costs and bill for services on a job-by-job basis.
 
  Customer Care and the Customer Information System. The Company has
implemented extensive customer support functions, including customer support
technicians available 24 hours a day, 7 days a week. These technicians are
trained to understand the Company's product and service offerings, and the
industry specific work flow of the Company's customers. Customer support
technicians routinely answer customer questions concerning product functions,
update address books, handle upgrade requests, and resolve product use issues.
In addition, customer calls are logged into call management software for
tracking and analysis purposes.
 
  The Company's CIS application allows customers to verify account information
and check the status of their transactions on-line. The CIS appears as an icon
on the customer's computer desk-top. When activated, the CIS accesses a menu
which provides the customer with several options, including viewing packages,
viewing account information or logging a help request. The "view packages"
option allows customers to view sent and received
 
                                      52
<PAGE>
 
package activity for user definable time periods between one hour and 90 days.
This option also provides key transmission statistics for each package sent or
received including date, time, size, content and file type. The account
information option allows customers to view relevant account information,
including billing information, site contact names and phone numbers and also
enables customers to update account information on-line. The "help" option
allows customers to log a help request by e-mailing questions or requests
directly to the Company's customer support group. See "--Network Management."
 
  WAM!PROOF. The Company has developed an application, "WAM!PROOF," which
allows customers to directly output across the WAM!NET Network to proofing
devices located at remote locations. WAM!PROOF was commercially released in
the second quarter of 1998. Proofs, which are physical representations of
printed output, are created throughout the production process at major check
points. Because work flow participants are often located in geographically
diverse locations, proofs have historically been printed and delivered by
overnight couriers to remote participants. WAM!PROOF enables customers to
print proofs in geographically diverse locations as if they were printing to a
proofer on their LAN, thereby reducing turnaround times and creating work flow
efficiencies. The Company has collaborated with leading manufacturers of
printing/proofing devices to ensure compatibility with WAM!PROOF. "WAM!PROOF
Ready" printing/proofing devices include devices made by Canon, Inc., Hewlett
Packard Company ("HP"), Imation Corp., Eastman Kodak Company, Tektronix, Inc.
and Xerox.
 
  WAM!BASE. The Company has also developed a wide area data repository
service, WAM!BASE, which provides WAM!NET Service users access to a remote
data archive and allows them to store, retrieve and manage data on a per-
megabyte cost basis. WAM!BASE is scheduled for commercial release in the
second half of 1998. The Company believes that the ability to manage and
access digital assets is becoming significantly more challenging due to
increasing digitalization in the Company's target industries. The
implementation of a workable and cost-effective solution requires the
integration of hardware, software and networking in a manner that is
accessible by multiple work flow partners and the reduction of redundant
processes and storage facilities. The implementation of such a system requires
substantial investments in capital equipment, systems integration and archive
management and often takes months to complete. Typical problems that can occur
are inadequate scalabilty, high operations costs and the lack of high-speed
and secure network infrastructure needed to share large digital data files.
 
  The Company believes that WAM!BASE provides a collaborative digital asset
management service that addresses the following significant issues for its
customers, and eliminates the need for investment in capital and archive
management. Given the speed at which technology changes and the need to ensure
reliable access to stored images, many participants are unwilling to make
these investments. Because it has been designed to be scaleable to the needs
of entire industries, WAM!BASE can spread infrastructure and operating costs
across numerous users. WAM!BASE is designed to offer a turn-key archiving
system that is cost competitive in relation to an individual customer's
investment in a local, stand-alone archiving system. Customers send their data
files over the WAM!NET Service to the WAM!BASE repository where files are
stored in customer configurable libraries. Customers will be charged a monthly
per megabyte fee for storage. Since customers are using the WAM!NET Service to
retrieve data from the WAM!BASE repository, they can obtain quick and secure
access to their data.
 
  WAM!BASE will provide collaborative access to stored data files. With
existing systems, industry participants working on the same job often store
multiple copies of the same data files because they do not have a
collaborative means of sharing file access. Participants who use WAM!BASE and
store files in their private library space, can control security access to
each individual file in their library, and can change security access
privileges at any time. This eliminates the need to store redundant copies of
files at multiple participant sites, can shrink cycle time by providing more
immediate access to important data files, and supports the job driven work
flow by enabling customers to control security access to images on a job-by-
job basis.
 
  When commercially released, the WAM!BASE service will use two mirrored
storage facilities linked by dedicated leased high bandwidth data connections.
The initial WAM!BASE storage centers will be located in
 
                                      53
<PAGE>
 
Minneapolis and Las Vegas within the NOCs already located in each city. Each
storage facility will be connected to the WAM!NET Network through redundant
links and customer data files will be stored in both locations. Customers will
use proprietary software provided by the Company to upload data to the storage
facilities and to browse, retrieve and forward files stored in the repository.
Customers will be able to restrict access to individual files, groupings of
files or complete libraries of files, manage the distribution of files, and
will also be able to catalogue, identify and search for stored files using
assigned attributes. The Company intends to locate additional mirrored storage
facilities in Europe and Asia/Pacific to accommodate international storage
requirements as needed.
 
SERVICE CONTRACTS
 
  The Company believes that the WAM!NET Service is achieving wide acceptance
among leading participants in the Graphic Arts industry, which in turn
encourages those with whom information is shared to subscribe to the WAM!NET
Service. Since it commercially released and commenced marketing of the WAM!NET
Service in March 1996, the Company has established a subscriber base of more
than 1,100 customer locations. As of February 11, 1998, 608 customer locations
were connected to the WAM!NET Network with an additional 561 contracted sites
expected to be installed during the first half of 1998, concurrent with the
installation of customer premise telephony access. As of April 30, 1998, the
Company's mix of service contracts was as follows:

  The Company's standard WAM!NET service contract is structured to assess
charges based on the minimum throughput capability (i.e., the minimum number
of megabytes per hour of the customer's data that the Company is obligated to
transfer via the WAM!NET Network), the monthly minimum volume and any usage in
excess of such monthly minimum volume. The pricing structure varies depending
on the monthly minimum fee and on volume, with higher minimum fees and higher
volumes generally resulting in lower per megabyte charges. Each WAM!NET
customer typically signs a service contract for a fixed term of one to three
years, at a specified location with minimum monthly fee of $250, $500, $1,000,
or $2,500 per month up to the specified volume. The standard service contract
is automatically renewable for additional one year periods at the Company's
then prevailing pricing structure, unless the customer gives notice of
termination at least 60 days prior to any automatic renewal date.
 
  Each service contract also grants the customer a limited, non-transferable
license to use the Company's proprietary software and certain other
intellectual property solely in connection with the customer's use of the
WAM!NET Service. Under each service contract, a customer generally agrees to
pay all taxes and fees imposed by governmental authorities, to be responsible
for all loss or damage to the NAD, to maintain certain insurance coverage for
the NAD, to preserve the Company's ownership of the licensed intellectual
property, to keep the NAD at the leased location, to return the NAD and all
licensed intellectual property at the termination of the service contract, and
to pay all of the Company's costs of enforcement in the event the customer
breaches the service contract.
 
  In addition to the standard service contract, the Company also negotiates
custom service contracts with large users of the Company's services. These
custom service contracts generally address specific customer work flow
requirements or multi-site installations, and typically contain scheduled
rebates and discounts based upon the number of third party trading-partners
who become connected to the WAM!NET Network and upon the volume
 
                                      54
<PAGE>
 
of data received from those third parties. These custom service contracts also
typically contain negotiated provisions relating to issues of non-
infringement, indemnification and damages for breach.
   
  The Company plans to offer WAM!BASE and WAM!PROOF services, as add-on
features to the WAM!NET Service. Subscribers for WAM!BASE and WAM!PROOF
services will sign an addendum to their WAM!NET service contract separately
licensing the software necessary to utilize the WAM!BASE or WAM!PROOF
services, as the case may be, and containing other appropriate terms. The
Company intends to furnish the WAM!BASE software without charge to customers
who agree to minimum monthly WAM!BASE storage fees. WAM!PROOF customers will
be charged for usage on a per megabyte basis like any other transmission over
the WAM!NET Network. The Company may require a nominal one-time license fee
covering the costs incurred by the Company to furnish the WAM!PROOF software.
    
SALES AND MARKETING
 
  Over the past year, the Company has spent significant time and resources
developing and building national marketing and sales capabilities, including
increasing its sales force from four to 36 people, who are located in New
York, Chicago, Los Angeles, Boston, Washington D.C., Minneapolis, San
Francisco, Dallas, Atlanta, Toronto and other major metropolitan areas. The
Company has created a product marketing organization responsible for the
definition, commercialization and ongoing management of its products and
services, and a direct sales organization responsible for all new sales and
account management functions. The product marketing organization is divided
into six functional groups, based on customer needs and demands, consisting of
a WAM!NET Service product group, a WAM!BASE product group, an Industry Smart
applications product group, a pricing group, a business analysis group and a
co-marketing group. The sales organization has also been split into five
groups, including an account executive group for new sales, a sales consultant
group for telesales support, a business development group for managing large
national accounts, an account management group for increasing utilization
within existing accounts and a product specialist group for new products.
 
  Primary marketing and sales strategies focus on making inroads with major
participants in the Company's target industries. In the Graphic Arts industry,
the Company's initial sales focus was on signing large commercial printers,
the final data destination in the digital work flow. Once several printers
subscribed to the WAM!NET Service, the Company's sales organization sought to
connect the printer's customers (pre-press firms, advertising agencies and
publishers) to the WAM!NET Network using a combination of sales and marketing
strategies. Such strategies include implementing promotional programs in which
printers promoted and marketed the WAM!NET Service to their customers and work
flow partners along with the Company's direct sales force. Similar strategies
are being applied by the Company to its other target industries.
 
  As more customers subscribe to the WAM!NET Service, the Company's strategic
sales focus is expected to shift. While new site acquisition will still be
important, significant resources will also be devoted to increasing inter-
connectivity among WAM!NET Service users and network traffic, in an effort to
embed the WAM!NET Service into an industry's work flow. As a result, the sales
organization may further employ account managers to work with customers to
help them better utilize WAM!NET Services and expand the circle of WAM!NET
users with whom they send and receive data.
 
  The Company's product marketing will focus on commercializing new features
and new products that are also intended to help increase the utilization of
the WAM!NET Network. This will include full scale commercialization of
Industry Smart applications like WAM!PROOF and WAM!BASE and the addition of
new Industry Smart features into existing products, including directory
services with white and yellow pages functionality, and directed billing
capabilities which will enable customers to reverse bill or bill third parties
for data transportation services.
   
  The Company has NADs in 44 states and in Canada. No single state or province
accounted for more than 10% of the Company's revenues for 1997 on a
consolidated basis without giving effect to the 4-Sight Acquisition. For its
fiscal year ended September 30, 1997, 4-Sight derived approximately 56% of its
revenues     
 
                                      55
<PAGE>
 
   
from sales in the United Kingdom, 25% from the United States, 10% from the
rest of Europe, and 9% from the rest of the world.     
 
INSTALLATION SERVICES
 
  The Company believes its ability to deliver consistently high quality
installation services will materially affect its ability to attract and retain
customers. The Company, therefore, has expended considerable resources to
build an installation function which coordinates and performs all aspects of
service installation for the customer When a new contract is signed, an
installation project manager is assigned to manage the installation. Site
surveys are completed to capture and confirm key customer information
including NAD placement, appropriate service level, account information and
network connectivity requirements. The project manager coordinates
installation of the NAD with on-site third-party installers and the Company's
circuit engineers, who test and certify connectivity and throughput between
the customer's site and the Distribution Hub.
 
  Installation of the WAM!NET Service consists of installing a simple,
graphical user interface ("GUI") on the customer's computer or LAN, connecting
the customer's computer or network to a NAD, and connecting the NAD through
telephone service to the nearest Distribution Hub. The Company has entered
into an agreement with National Computer Systems ("NCS"), a national provider
of computer installation and maintenance services, to provide installation,
maintenance and repair services on customer sites.
 
NETWORK ARCHITECTURE
 
  The WAM!NET Network is comprised of national, regional and local
Distribution Hubs that are owned by the Company and interconnected redundantly
with high-bandwidth leased telephone circuits. The Company currently maintains
23 Distribution Hubs, located in major United States and Canadian cities,
London, England and Paris, France. The Company also operates two mirrored NOCs
in Minneapolis and Las Vegas through which it manages and operates all data
transmission. The Company has also contracted with an independent third-party
for the provision of satellite transmission services for added redundancy with
respect to services provided to Time. The Company is currently negotiating to
employ satellite services to add redundancy for the entire WAM!NET Network.
   
  The WAM!NET Service uses technology similar to the Internet, such as ISDN,
DS1 (1.54 megabits per second), DS3 (45 megabits per second), frame relay and
ATM. Because the WAM!NET Service provides managed data package traffic, the
available bandwidth of the WAM!NET Network is not being cluttered with the
large amount of random data traffic that exists on a public network such as
the Internet. The Company has sized aggregation points throughout the WAM!NET
Network to ensure that no backbone connection is smaller than any "last mile"
connection (i.e., from a NAD at a customer site to a Distribution Hub).     
 
  The hub infrastructure consists of large Cisco Systems, Inc. ("Cisco")
routers which are co-located with WorldCom points of presence and which
primarily route data traffic across the WAM!NET back-bone. The 23 Distribution
Hubs are interconnected with a meshed DS3 ATM back-bone provided by WorldCom.
Additional network diversity is provided by a layer of private lines leased
from Sprint Corporation ("Sprint") which primarily serve as network back-up.
Local loop connections between Distribution Hubs and NADs at customer sites
are provided almost exclusively by WorldCom and regional bell operating
companies. The Company's policy is to procure local loop lines from the
lowest-cost, highest-quality provider, and the Company has business
relationships with approximately 15 telephony providers in North America.
Network traffic patterns are continuously monitored and the existing network
back-bone infrastructure is operating at approximately 5% to 10% of its
capacity. Operating agreements with WorldCom and MCI Communications
Corporation ("MCI") enable the Company to increase backbone bandwidth to
accommodate planned growth on an as-needed basis.
 
  The WAM!NET Network incorporates multiple firewalls, constant monitoring and
other security features to prevent unauthorized access or tampering with
either the Company's or the customers' data systems. For security purposes,
the WAM!NET Network is designed to prevent customers from gaining unauthorized
access to the
 
                                      56
<PAGE>
 
WAM!NET Network through a NAD, from logging onto any other device attached to
the WAM!NET Network and from exploring the WAM!NET Service or activating or
controlling any of its other functions. The Company's software installed on
the user's computer only delivers files to or from the NAD.
 
NETWORK MANAGEMENT
 
  The Company provides customers toll-free access to its technical services
support team 24 hours a day, 7 days a week. The Company believes that because
its customers are in time sensitive, data intensive industries, they rely on
the WAM!NET Service to provide guaranteed delivery and throughput. The Company
has sought to build reliability into its network by interconnecting all
Distribution Hubs and NOCs with at least two redundant paths so that in the
event of network line failures data can still be transmitted. In addition,
automated network monitoring software from HP has been installed and
configured to provide continuous monitoring capabilities, including an alarm
system that automatically alerts network engineers of problems. Key aspects of
the WAM!NET Network are continuously monitored, including NOC equipment,
Distribution Hub equipment, backbone lines, local customer connections and the
NADs. The network management team is trained to proactively work with
telephony and on-site service providers using specially developed processes to
identify and resolve network issues quickly and efficiently.
 
MANUFACTURING
 
  The Company conducts only limited equipment assembly functions. The Company
presently installs proprietary software and assembles standard computer,
router and power management equipment components into steel housings for use
as NADs, Distribution Hubs and equipment in the NOCs. The equipment housing is
manufactured by a third party to the Company's specifications. The Company
contracts with third parties for installation of NADs at customer sites. See
"--Supplier Relationships--Installation and Field Maintenance." The Company
installs Distribution Hubs and equipment in the NOCs. The Company intends to
outsource the assembly of NADs.
 
SUPPLIER RELATIONSHIPS
 
  Equipment. The Company has procurement arrangements with Silicon Graphics,
Inc. ("SGI"), Cisco and Osicom Technologies, Inc. for certain computer
equipment, routers and computer interface cards used in the WAM!NET Network.
These arrangements qualify the Company for discounts off participant list
pricing for such equipment. The Company is presently negotiating more formal
supply arrangements with Cisco and SGI. The Company also purchases certain
high volume data storage equipment from HP and Hitachi Data Systems
Corporation under supply agreements.
 
  Installation and Field Maintenance. The Company has an agreement with NCS to
provide installation, maintenance and repair services on customer sites.
 
  Telephone Carriage and Infrastructure Support. The Company currently leases
local loop and long distance telephone carriage in the United States from
WorldCom. In addition, the Company has procurement agreements with MCI and
Sprint, and purchases local loop telephony services from approximately 15
local loop providers.
 
  None of the supplier agreements described or contemplated above contains a
long-term commitment on behalf of the supplier. See "Risk Factors--Dependence
on Third-Party Suppliers for Equipment and Services."
 
COMPETITION
 
  Despite what the Company believes to be meaningful product differentiation,
the Company faces competition in the provision of digital data transportation
and archiving services, including from companies that have substantially
greater financial, technological, marketing, and research and development
resources than the Company and which have an established presence in markets
that the Company serves. The Company's
 
                                      57
<PAGE>
 
competitors include major long-distance companies, regional Bell operating
companies, Internet service providers, systems integrators, such as Digital
Art Exchange, and other smaller companies which manage routers as part of more
comprehensive public, private and virtual private wide area network service
offerings. Some companies have begun to offer data communications networks
which use standard communication technology in conjunction with emerging
frame-relay and ATM technology. The architecture of these networks is similar
to that of the WAM!NET Service. These competitors, including the Sprint DRUMS
network, MCI SMDS telecommunications service and a joint venture arrangement
between AT&T Corp. and Xerox, offer some of the services the Company offers or
plans to offer in the future. Additionally, a new competitive service called
the Graphic Arts Digital Network which directly targets the WAM!NET Service
was announced in Spring 1997, but has not yet been released. This service will
be provided by a joint venture between British Telecommunications and Sytek.
Pricing, product and service information are not yet available for that
service. While the Internet is not currently an effective competitor to the
WAM!NET Service, efforts are under way, through a consortium of research
universities, the Federal Government's Very-High-Performance Backbone Network
Service and several major corporations, to create "Internet2." Press stories
on Internet2 suggest that it will include commercial channels through which
large amounts of data can be moved securely between researchers or companies.
The commercial availability of Internet2 is not expected before 2003.
 
  In addition, the Company faces competition from overland and air courier
services, who transport magnetic tape or optical disk copies of digital data
to their desired locations.
          
  The Company believes the major competitive factors in the digital data
delivery industry are price, reliability and capacity. The Company's
technologically higher-end competitors that offer high bandwidth dedicated
lines have the capability of reliably providing high capacity transmission,
but with the comparatively higher user costs involved in leasing dedicated
point to point lines, dedicated equipment costs and attendant information
management fees. Lower-end competitors, such as standard telephone modems or
the Internet, can compete with the Company on a cost basis, but do not provide
the managed reliability or capacity of the WAM!NET System. The Company
believes that it is the only provider of a turn-key, managed digital data
delivery service with a purpose-built network tailored to target industries'
needs which addresses the price, reliability and capacity requirements of data
intensive industries.     
 
GOVERNMENT REGULATION, STANDARDS
 
  North America. The Company purchases telephone equipment, routers and relays
that are used in the WAM!NET Network from telecommunications equipment
manufacturers and combines that equipment with Company-provided software and
telephone circuits provided by common carriers regulated by the FCC the CRTC
and various state regulatory agencies. The Company believes that under the
FCC's interpretation of the Communications Act of 1934, as amended, the
services which it offers to its customers are interstate information
(enhanced) services. Consequently, it is not required to obtain licenses or
other approvals from the FCC or state regulatory agencies to offer such
services. If the Company's services were deemed to be intrastate services,
certain state regulatory agencies might seek to assert jurisdiction over the
Company's offerings. If that were to occur, the Company could be required to
expend substantial time and money to acquire the appropriate licenses and to
comply with state regulations. The Company also believes that, under the
CRTC's interpretation of Canadian law, the services that the Company offers do
not require it to obtain telecommunications permits or approvals in Canada.
 
  Worldwide. The Company believes that European Union directives require that
member states permit the provision of the Company's services on a competitive
basis. Bilateral agreements exist between the United States and Japan and the
United States and Hong Kong which encourage cross-border provision of enhanced
services like those offered by the Company. Pursuant to commitments in the WTO
General Agreement on Trade and Services, over fifty governments have agreed to
permit provision of enhanced services (i.e., value-added) by nationals of WTO
member countries. Nevertheless, certain other countries in Europe, Asia and
elsewhere in the world might seek to license and regulate the Company's
services. Any such license or regulation may limit, delay or increase the
costs of operations as associated with the international locations to which
the Company may desire to expand.
       
                                      58

  Medical Imaging. The Company intends to offer its WAM!NET Service and
WAM!BASE service as medical imaging applications for transmitting, storing and
retrieving medical data for primary diagnostic purposes. The Company is
currently participating in a test of the medical image transmission
application of the WAM!NET Service between a hospital and a remotely located
clinic, and intends to commence testing of the WAM!BASE storage and retrieval
functions during the fourth quarter of 1998. Any medical imaging applications
offered for primary diagnostic purposes are required to comply with the Food
and Drug Act, and regulations promulgated thereunder by the FDA. Under
recently adopted FDA regulations, both the WAM!NET Service's data transmission
application and the WAM!BASE data storage and retrieval application are
classified as Class I devices that do not perform "irreversible data
compression." Prior to adoption of those regulations, both the transmission
and storage functions were classified as Class II devices, and the Company had
received marketing clearance from the FDA for data transmission pursuant to a
510(k) Premarket Notification filing. The Company's medical image
transmission, storage and retrieval applications conform to the DICOM industry
standards, which are the industry accepted standards utilized by major medical
imaging equipment manufacturers in the domestic health care industry. The
Company works with medical imaging equipment manufacturers to ensure
compatibility of the WAM!NET and WAM!BASE applications with their medical
imaging equipment.     
 
RESEARCH AND DEVELOPMENT
 
  The Company's employees have significant experience in the research,
development, design, engineering, implementation and management of complex
software and networking systems. Six of the Company's employees hold advanced
computer engineering degrees. The Company's current research and development
activities are focused on completing development of additional functions,
including the next generation of network and transportation management
software and protocols necessary to provide applications such as broadcast
transmissions, queue management, directed billing, directory services and job
ticketing, including integrating such features into the shipping and customer
information management facilities. The Company utilizes its technical
capabilities to monitor and evaluate developments in computer hardware and
software and in relay and telephony equipment and, to the extent possible, to
incorporate appropriate advancements or enhancements into the WAM!NET Service
in a timely fashion.
 
INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS
 
  It is the Company's policy to protect its intellectual property, to seek
patent protection for those aspects of its technology that the Company
believes may be patentable and to preserve any copyrights or trade secrets (to
the extent not disclosed in any patent) that may be applicable to the WAM!NET
Service, the WAM!PROOF and WAM!BASE services and their related software.
   
  The Company is designing or has designed most of the proprietary software
necessary for the management of the WAM!NET Service, including NAD operations
and the GUI, CIS, WAM!PROOF and WAM!BASE applications. The Company believes
that its proprietary software and trade secrets applicable to the operation of
the WAM!NET Service and the WAM!BASE data archiving system may be of equal or
greater importance to the Company than patent or copyright protection. The
Company is not aware of any claims of infringement of patents or other
intellectual property belonging to others. However, the Company has conducted
only a limited inquiry regarding the possibility of other infringement. Given
the recent acquisition of 4-Sight, with its substantial international
presence, the Company will increasingly offer its products and services in
foreign countries. However, some of these countries may lack intellectual
property protection that is comparable to that afforded by the intellectual
property laws of the United States. See "Risk Factors--Intellectual Property
and Proprietary Rights."     
 
  The Company has entered into confidentiality agreements with certain of its
employees, consultants and others to protect the Company's proprietary
information and trade secrets.

LIABILITY AND INSURANCE
   
  The WAM!NET Service uses an assemblage of telecommunications equipment,
software, operating protocols and proprietary applications for high speed
transmission of large quantities of data among multiple locations. In such
operations, it is possible that data files may be lost, altered or distorted.
Moreover, the Company's targeted industries' businesses are extremely time
sensitive, and delays in delivering data may cause a significant loss to a
customer using the network for managed data delivery service. The WAM!NET
Service, and future enhancements or adaptations, may contain undetected design
faults and software "bugs" that, despite testing by the Company, are
discovered only after the system has been installed and used by customers.
Such faults or errors could cause delays or require design modifications that
could adversely affect the Company's competitive position and results of
operations. The Company obtains contractual agreements from its customers
limiting the Company's liability for damages resulting from errors in the
transportation of data to a maximum of $100 per transmission. Nevertheless,
the Company may still be subject to significant claims for data losses in the
transportation of data over the WAM!NET Service. In addition to general
business liability insurance coverage, the Company presently maintains errors
and omissions insurance coverage issued by St. Paul Fire and Marine Insurance
Company in the amount of $1.0 million per occurrence and $5.0 million for all
occurrences relating to the transportation of data over the WAM!NET Service.
In addition, the Company presently maintains $1.0 million of business
interruption insurance coverage against losses from floods, earthquakes and
other natural disasters.     
 
EMPLOYEES
 
  Including its officers, the Company presently employs 405 persons. The
Company's executive and technical personnel have significant experience in the
design, programming, implementation, marketing, sales and support of complex
data networks and software programs. The Company considers its employee
relations to be good. None of the Company's current employees are subject to a
collective bargaining agreement.
 
FACILITIES
 
  The Company occupies approximately 45,000 square feet of office space
located in a modern facility in an industrial park complex in Bloomington,
Minnesota, a suburb of Minneapolis. The building is occupied under a 99 month
lease which expires in November 2005. To meet its future space requirements,
the Company is currently considering construction activities to reconfigure
its existing facility for greater space efficiency. The Company's leased
properties also include: (i) an approximately 18,000 square foot manufacturing
and warehousing facility located in Minneapolis, (ii) an approximately 1,540
square foot office facility located in Minneapolis, where one of the Company's
NOCs is located, (iii) an approximately 7,970 square foot facility located in
Las Vegas, Nevada where the Company's other NOC is located and which serves as
a backup customer service center, (iv) an approximately 1,500 square foot
office facility located in Missoula, Montana where the headquarters of
FreeMail, Inc., an entity acquired by the Company in December 1997, is
located, (v) small offices in Toronto, New York, Chicago, and Washington, D.C.
for use by the Company's business development managers and account executives
stationed in those cities, and (vi) an approximately 18,800 square foot office
facility located in Minneapolis, which previously served as the Company's
headquarters and which the Company intends to sub-lease. In addition, 4-Sight
currently leases properties in (i) Bournemouth, Dorset, England, (ii) Hamburg,
Germany, (iii) Woburn, Massachusetts and (iv) West Des Moines, Iowa.

STOCK OPTION PLANS
   
  The Company's Stock Option Plan (the "1994 Plan") was adopted in September
1994 by the Company's Board of Directors and was approved by the shareholders
of the Company in October 1994. The 1994 Plan has been subsequently amended,
most recently on April 24, 1998 (as so amended and restated in April 1998, the
"Amended 1994 Plan") in conjunction with the adoption of the Company's 1998
Combined Stock Option Plan (the "1998 Plan" and, collectively, the "Plans"),
to reflect the Company's name change to WAM!NET Inc., to incorporate prior
amendments to the 1994 Plan, to provide that no new options be granted under
the 1994 Plan and to limit the number of shares of Common Stock available for
issuance under the Amended 1994 Plan to 7,000,000. Each Plan is currently
administered by the Company's Board of Directors. The 1998 Plan and the
amendments to the 1994 Plan adopted by the Board of Directors on April 24,
1998 received shareholder approval on May 30, 1998.     
   
  The Amended 1994 Plan and the 1998 Plan provide for the granting of Common
Stock options which qualify as "incentive stock options" under Section 422 of
the Internal Revenue Code of 1986, as amended (the "Code"), as well as the
granting of "nonqualified options." Under each Plan, the Board or, if the
Board appoints one, a "Stock Option Committee" has complete discretion to
select the optionees and to establish the terms and conditions of each option,
subject in all cases to the provisions of a Plan and applicable provisions of
the Code. Options granted under a Plan are not transferable and are subject to
various other conditions and restrictions. Participation in the Amended 1994
Plan is limited to officers and regular full-time executive, administrative,
professional, production and technical employees of the Company or a
subsidiary of the Company, who are salaried employees of the Company or a
subsidiary of the Company, and consultants or the Company or a subsidiary.
Non-employee directors of the Company may be granted nonqualified options.
Participation in the 1998 Plan is limited to employees of the Corporation or a
subsidiary of the Corporation and to non-employee directors and non-employee
consultants. The 1998 Plan provides that without amending such 1998 Plan, the
Stock Option Committee may grant options to eligible employees who are foreign
nationals on such terms and conditions different from those specified in this
Plan as may in the judgment of the committee be necessary or desirable to
foster and promote achievement of the purposes of the 1998 Plan, and, in
furtherance of such purposes the Committee may make such addenda,
modifications, amendments, procedures, subplans and the like as may be
necessary or advisable to comply with provisions of laws in other countries in
which the Company operates or has employees. An addendum to the 1998 Plan
extends the benefits of stock options granted under the 1998 Plan to employees
of the Company and its subsidiaries who are residents of the United Kingdom.
    
  7,000,000 shares of Common Stock have been reserved for issuance under the
Amended 1994 Plan and a total of 25,000,000 shares of Common Stock have been
reserved for issuance under the 1998 Plan, subject to adjustment for stock
splits or recapitalizations. Shares subject to canceled, unexercised, lapsed
or terminated options are available for subsequently granted options under a
Plan. The exercise price of all incentive stock options granted under a Plan
must be at least equal to the fair market value of the shares on the date of
grant, and the maximum term of each option is ten years. Under the terms of a
Plan, the aggregate fair market value of the Common Stock (determined at the
date of the option grant) for which any employee may first exercise incentive
stock options in any calendar year may not exceed $100,000. Upon exercise of
an option, payment of the exercise price in cash is required, or, at the
discretion of the Company, by the delivery of Common Stock of the Company
already owned by the optionee or a promissory note for all or a portion of the
exercise price of the shares so purchased or a combination of the foregoing.
There is no express limitation on the duration of a Plan; provided, however,
that incentive stock options may not be granted after the date that is ten
years from the date of Shareholder approval of a Plan. The Board may terminate
a Plan and, subject to certain limitations, may amend the Plan at any time. As
of the date hereof, there were 5,764,900 options issued and outstanding under
the Amended 1994 Plan, consisting of incentive stock options to employees to
purchase a total of 5,454,900 shares of Common Stock at exercise prices
ranging from $0.45 to $3.90 per share, and non-qualified stock options to
directors to purchase a total of 310,000 shares of Common Stock at an exercise
price of $0.962 per share. No options have been granted under the 1998 Plan.
 
  In addition to options granted under the Plans, the Company has also granted
certain officers and consultants options to purchase a total of 5,125,000
shares of Common Stock at exercise prices ranging from $0.45 to $3.90 per
share.

                    CERTAIN TRANSACTIONS AND RELATIONSHIPS
 
  WorldCom has the right to elect a majority of the Board of Directors of the
Company and is a principal shareholder of the Company. In September 1996, the
Company issued to WorldCom a $5.0 million Convertible Subordinated Note due
September 30, 1999 (the "WorldCom Convertible Note"). Interest on the WorldCom
Convertible Note accrues at an annual rate of 10%, payable semi-annually,
commencing with the first payment on March 30, 1997. At any time prior to
September 30, 1999, WorldCom may convert the principal amount of the WorldCom
Convertible Note into shares of Common Stock at a conversion price of $1.00
per share, subject to adjustment in the event of stock splits, reorganizations
or recapitalizations. Payment of principal and interest on the WorldCom
Convertible Note is subordinated to existing and future obligations of the
Company for money borrowed from bank, trust, insurance or other financial
institutions. WorldCom has agreed to defer all cash payments in respect of the
WorldCom Convertible Note until a date that is 180 days following the Stated
Maturity of the Notes. The shares of Common Stock underlying the WorldCom
Convertible Note are subject to certain registration rights. See "Description
of the Company's Securities--Certain Options, Warrants, Convertible
Subordinated Debt and Registration Rights."
 
  In November 1996, the Company and WorldCom entered into a Preferred Stock,
Subordinated Note and Warrant Purchase Agreement (the "WorldCom Agreement").
Pursuant to the WorldCom Agreement, the Company issued 100,000 shares of its
Class A Preferred Stock, par value $10.00 per share, to WorldCom for an
aggregate purchase price of $1.0 million. Except for voting with respect to
the election of Directors, holders of shares of Class A Preferred Stock are
entitled to one vote for each share held of record, voting together with the
holders of Common Stock as a single class, on all matters submitted to a vote
of shareholders. With respect to the election of Directors, holders of Class A
Preferred Stock, voting separately as a class, are entitled to elect a
majority of the Board of Directors. Holders of shares of Class A Preferred
Stock, in preference to holders of shares of Common Stock, are entitled to
receive a quarterly dividend in the amount of $0.175 per share, payable in
cash or in kind, commencing on January 1, 1997, if declared by the Board of
Directors. If the net earnings of the Company in a particular year are
insufficient to pay such dividend, the unpaid amount accumulates and must be
paid in subsequent years before any dividends are paid on shares of Common
Stock. At any time that quarterly dividends owing to holders of shares of
Class A Preferred Stock are in arrears, the Company may not, without the
consent of the Directors elected by the holders of shares of Class A Preferred
Stock, (i) declare or pay dividends on any stock ranking junior to the Class A
Preferred Stock, (ii) declare or pay dividends on any stock ranking a parity
with the Class A Preferred Stock, unless such dividends are paid ratably to
the holders of shares of Class A Preferred Stock, (iii) redeem, purchase or
otherwise acquire for consideration any share of stock ranking junior to the
Class A Preferred Stock or (iv) redeem or purchase or otherwise acquire for
consideration any shares of Class A Preferred Stock, or any shares of stock
ranking on a parity with the Class A Preferred Stock, except in accordance
with an offer to all holders upon such terms as the Board of Directors shall
determine in good faith will result in a fair and equitable treatment among
the respective series or classes of stock. Holders of shares of Class A
Preferred Stock are entitled to preferential distributions upon liquidation
equal to $10.00 per share of Class A Preferred Stock plus accumulated and
unpaid dividends thereon. The Company is required to redeem all shares of
Class A Preferred Stock outstanding as of December 31, 1999 at a redemption
price equal to $10 per share plus an amount equal to all accumulated and
unpaid dividends thereon. WorldCom has agreed that no cash dividends or
distributions will be payable by the Company on the Class A Preferred Stock
owned by WorldCom, and the Class A Preferred Stock owned by WorldCom will not
be redeemed by the Company for cash, until a date that is 180 days following
the Stated Maturity of the Notes. WorldCom is the sole holder of shares of
Class A Preferred Stock. See "Description of the Company's Securities--
Preferred Stock."
 
  Pursuant to the WorldCom Agreement, the Company also issued to WorldCom a
$28.5 million Subordinated Note due December 31, 2003 (the "WorldCom
Subordinated Note"), of which $20.4 million aggregate principal amount was
outstanding as of December 31, 1997. The WorldCom Subordinated Note accrues
interest at an annual rate of 7%, payable semi-annually, commencing March 31,
1997. Payment of principal and interest on the WorldCom Subordinated Note is
subordinated to existing and future obligations of the Company for money
borrowed from bank, trust, insurance or other financial institutions. WorldCom
has
 
                                      68
<PAGE>
 
agreed to defer all cash payments in respect of the WorldCom Subordinated Note
until a date that is 180 days following the Stated Maturity of the Notes. See
"Descriptions of Certain Indebtedness."
 
  In February 1998, in connection with the Initial Offering, WorldCom agreed
to defer all cash payments of principal (or premium on) or interest on, or
dividend, distribution or other payment in respect of the WorldCom Convertible
Note, the shares of Class A Preferred Stock owned by WorldCom and the WorldCom
Subordinated Note until a date that is 180 days following the Stated Maturity
of the Notes. The agreement also provides that the payment of the principal of
and interest on the WorldCom Convertible Note and the WorldCom Subordinated
Note may be accelerated only in the event of the acceleration of the payment
of the principal amount of the Notes following an Event of Default with
respect to the Notes. The agreement grants WorldCom an option to convert (a)
interest otherwise due on the WorldCom Convertible Note and deferred pursuant
to WorldCom's agreement, and (b) the interest accrued on the outstanding
principal amount of the WorldCom Subordinated Note from December 31, 2003
through the date such amount is paid pursuant to WorldCom's agreement into
shares of Common Stock at the per share price on the date of such conversion.
 
  Pursuant to the WorldCom Agreement, the Company also issued to WorldCom
warrants to purchase, on or before December 31, 2000, up to 20,787,500 shares
of the Company's Common Stock at an initial exercise price of $0.962 per
share, subject to adjustment in the event of stock splits, reorganizations or
recapitalizations (the "WorldCom Warrants"). The exercise price increased to
$0.982 per share on March 31, 1997, and thereafter will automatically increase
by the amount of $0.016 per share on the last day of each calendar quarter,
subject to certain abatement provisions. The exercise price is currently $1.03
per share. The WorldCom Warrants are subject to certain registration rights.
See "Description of the Company's Securities--Certain Options, Warrants,
Convertible Subordinated Debt and Registration Rights."
 
  The WorldCom Agreement provides that if the Company is not publicly held by
the year 2000 its managers and Board of Directors will obtain an independent
valuation by a nationally recognized investment bank of the fair market value
per share of the Company's Common Stock, without any premium allocated for any
controlling interest (the "Tender Valuation"). Upon receipt of the Tender
Valuation, WorldCom may, but is not required to tender (the "First Tender") to
purchase all outstanding shares of Common Stock and all outstanding options,
warrants, convertible securities and other rights to purchase shares of Common
Stock (collectively, "Company Common Securities") for at least the per share
amount of the Tender Valuation. If the owners of a majority of the then
outstanding shares of the Company's Common Stock (excluding shares held by
WorldCom or its affiliates) reject the First Tender, WorldCom will have 60
days following such rejection to again tender (the "Second Tender") to
purchase the same securities. During such 60-day period, the Company will use
its good faith efforts to determine what offer price would be acceptable to
the owners of such shares and will communicate such information to WorldCom.
Subject to certain conditions, WorldCom will sell and the Company will
purchase the WorldCom Warrants, any shares acquired upon exercise of the
WorldCom Warrants and any shares acquired upon the conversion of the WorldCom
Convertible Note (collectively, the "WorldCom Securities") if (i) WorldCom
fails to make the First Tender within 90 days after receipt of the Tender
Valuation; (ii) owners of a majority of the then outstanding shares of Common
Stock (excluding shares held by WorldCom or its affiliates) reject the First
Tender and WorldCom makes no Second Tender; or (iii) owners of a majority of
the then outstanding shares of Common Stock (excluding shares held by WorldCom
or its affiliates) reject the Second Tender. The Company's purchase price for
the WorldCom Securities will be as follows:
 
  (a) If WorldCom fails to make the First Tender, an amount equal to the
      Tender Valuation (or the spread between the Tender Valuation and the
      exercise price in the case of warrants).
 
  (b) If the First Tender is rejected by the Company's shareholders and
      WorldCom does not make the Second Tender, an amount equal to the
      purchase price offered by WorldCom in the First Tender (or the spread
      between the offer price and the exercise price in the case of
      warrants).
 
  (c) If the Second Tender is rejected by the Company's shareholders, an
      amount equal to the purchase price offered by WorldCom in the Second
      Tender (or the spread between the offer price and the exercise price in
      the case of warrants).
 
                                      69
<PAGE>
 
  The Company will have nine months in which to pay the purchase price for the
WorldCom Securities. From the time the obligation of the Company to purchase
the WorldCom Securities arises until the expiration of such nine-month period,
Edward J. Driscoll III and Allen L. Witters will jointly hold a limited proxy
with regard to all of the WorldCom Securities. If the Company fails to timely
pay the purchase price for the WorldCom Securities, WorldCom will be relieved
of all obligations to sell such securities to the Company, the Company will
have no right to cause WorldCom to sell such securities and the Company will
not be obligated to pay the purchase price for such securities. The parties
have agreed to waive their respective obligations thereunder if the Company
determines to become, and thereafter becomes, a publicly-held company.
 
  In December 1996, WorldCom, Edward J. Driscoll III and Allen L. Witters
executed a Right of Refusal Agreement which provides: (i) for a restriction on
transfer by Mr. Driscoll and Mr. Witters of the shares of Common Stock of the
Company held by them as of the date thereof (the "Shares") and (ii) that in
the event Mr. Driscoll or Mr. Witters desires to sell his Shares, then he
shall offer to the other a right of first refusal and, in the event the other
does not elect to purchase such Shares, he shall offer to WorldCom a right of
second refusal.
   
  In September 1997, the Company entered into the Revolving Credit Facility.
The maximum amount that can be borrowed under the Revolving Credit Facility is
$25.0 million. WorldCom has guaranteed the payment of all amounts owed under
the Revolving Credit Facility, and, accordingly, the Company must obtain
WorldCom's consent prior to obtaining any advances under the Revolving Credit
Facility. See "Descriptions of Certain Indebtedness." In consideration of
WorldCom's guaranty, the Company granted to WorldCom 8,396,170 Class A
warrants and 14,204,835 Class B warrants to purchase shares of the Company's
Common Stock at an initial exercise price of $3.90 per share, subject to
adjustment in the event of stock splits, reorganizations or recapitalizations.
The Class A warrants may be exercised at any time on or before December 31,
2000. The Class B warrants begin to vest after the 24th month of the Revolving
Credit Facility depending upon the outstanding balance under the Revolving
Credit Facility at certain times and whether certain qualified repayments are
made thereunder. If the Company repays all obligations under the Revolving
Credit Facility prior to the 24th month with certain qualified repayments, no
Class B warrants will vest. The Class A warrants and Class B warrants are
subject to certain registration rights. See "Description of the Company's
Securities--Certain Options, Warrants, Convertible Subordinated Debt and
Registration Rights." At June 30, 1998, the Company had $0 borrowed under the
Revolving Credit Facility.     
 
  WorldCom has also guaranteed the performance of the Company's obligations
under a Service Provision Agreement, dated July 18, 1997, between the Company
and Time.
   
  The Company has entered into service arrangements with WorldCom, including
an Application for Data Services pursuant to which WorldCom provides the
Company with interexchange telecommunications service, frame relay service and
ATM service, and co-location agreements pursuant to which the Company leases
space for its Distribution Hubs. The Company believes that these arrangements
are at terms that are similar to those that could be obtained from an
independent third party on an arm's-length basis. Pursuant to the Company's
agreements with WorldCom, the Company has guaranteed monthly usage levels of
data communications with WorldCom totaling in aggregate approximately $3.0
million, $3.0 million and $1.8 million for the years ended December 31, 1998,
1999 and 2000, respectively.  In the event these agreements are terminated
prior to their expiration date, the Company will be liable to WorldCom for
termination contingencies totaling in aggregate approximately $2.9 million,
$0.9 million and $0.4 million for the years ended December 31, 1998, 1999 and
2000, respectively. The Company's data communications expense under
telecommunication contracts with WorldCom was approximately $0, $2,000 and
$1.4 million for the years ended December 31, 1995, 1996 and 1997,
respectively.     
 
  Edward J. Driscoll, Jr., purchased 250,000 shares of Common Stock at the
Company's inception in 1994. As consideration for such shares, Mr. Driscoll
paid the Company $500 and agreed to provide certain consulting services to the
Company. In January 1998, Mr. Driscoll was granted an option to purchase up to
200,000 shares of the Company's Common Stock at a price of $3.90 per share as
partial consideration for his agreement to provide certain services to the
Company. Mr. Driscoll is a shareholder of Larkin, Hoffmann, Daly & Lindgren,
Ltd., which provides certain legal services to the Company. Mr. Driscoll is
the father of Edward J. Driscoll III, the Company's Chairman of the Board,
President and Chief Executive Officer.

  The Company's marketing services were performed by Kauffman Marketing Group,
Inc. from November 1995 to December 1997. The former President of Kauffman
Marketing Group, Inc., John Kauffman, joined the Company as Vice President of
Strategic Marketing and Communications in December 1997. During the years
ended December 31, 1995, 1996 and 1997, the Company incurred marketing
expenses of approximately $0.0, $0.3 million and $1.6 million, respectively,
to such firm for marketing services. In addition, Mr. Kauffman was granted, in
July 1997, an option to purchase up to 225,000 shares of Common Stock at a
price of $0.962 per share and Mr. Kauffman was granted, in December 1997, an
option to purchase up to 350,000 shares of Common Stock at a price of $3.90
per share.
   
  In consideration for David Townend's sale of 31,680,000 ordinary shares of
4-Sight to the Company and its subsidiaries in connection with the 4-Sight
Acquisition, Mr. Townend received $7,991,094 and 1,317,300 shares of Common
Stock. Furthermore, Mr. Townend is entitled to receive 48.95% of the 750,000
shares of Common Stock which comprises the deferred consideration for the
purchase of 4-Sight, which shares are conditioned upon the achievement of
certain revenue goals by the Company following the 4-Sight Acquisition.

                    DESCRIPTION OF THE COMPANY'S SECURITIES
 
GENERAL
 
  The Company's authorized capital stock consists of 100,000,000 shares, of
which 90,000,000 shares are designated as Common Stock, 100,000 shares are
designated as Class A Preferred Stock, par value $10.00 per share ("Class A
Preferred Stock"), and 9,900,000 shares are designated as Undesignated Stock.
 
COMMON STOCK
   
  The Company currently has outstanding 9,271,363 shares of Common Stock. An
additional 68,606,626 shares are reserved for issuance upon exercise of
outstanding options and warrants, conversion of convertible debt securities
and for payment of the portion of the consideration of the 4-Sight Acquisition
that is subject to the satisfaction of certain conditions. The holders of
Common Stock are entitled to one vote for each share held of record on all
matters submitted to a vote of shareholders. There is no cumulative voting for
the election of directors, which means that the holders of more than 50% of
the outstanding Common Stock voting for the election of directors can elect
all of the directors of the Company to be elected by the holders of Common
Stock. As discussed below, the holders of Class A Preferred Stock, voting
separately as a class, are entitled to elect a majority of the Board of
Directors. Subject to the preferences of the Class A Preferred Stock and any
other class or series of outstanding preferred stock, holders of Common Stock
are entitled to receive ratably such dividends as may be declared by the Board
of Directors out of funds legally available therefor and are entitled to share
ratably in all assets of the Company available for distribution to holders of
the Common Stock upon liquidation, dissolution or winding up of the affairs of
the Company. Holders of Common Stock have no preemptive, subscription or
conversion rights and there are no redemption or sinking fund provisions
applicable thereto. All outstanding shares of Common Stock are fully paid and
nonassessable. All of the Company's outstanding shares of Common Stock have
been acquired from the Company through transactions not involving a public
offering, and, as such, all such shares are deemed "restricted securities"
pursuant to Rule 144(a)(3)(i) of the Securities Act.     
 
PREFERRED STOCK
 
  In November 1996, the Company issued 100,000 shares of Class A Preferred
Stock to WorldCom for an aggregate purchase price of $1.0 million. Except for
voting with respect to the election of Directors, holders of shares of Class A
Preferred Stock are entitled to one vote for each share held of record, voting
together with the holders of Common Stock as a single class, on all matters
submitted to a vote of shareholders. With respect to the election of
Directors, holders of Class A Preferred Stock, voting separately as a class,
are entitled to elect a majority of the Board of Directors. Holders of shares
of Class A Preferred Stock, in preference to holders of shares of Common
Stock, are entitled to receive a quarterly dividend in the amount of $0.175
per share, payable in cash or in kind, commencing January 1, 1997, if declared
by the Board of Directors. If the net earnings of the Company in a particular
year are insufficient to pay such dividend, the unpaid amount accumulates and
must be paid in subsequent years before any dividends are paid on shares of
Common Stock. At any time that the quarterly dividends owing to holders of
shares of Class A Preferred stock are in arrears, the Company may not, without
the consent of the Directors elected by the holders of Class A Preferred
Stock, (i) declare or pay dividends on any stock ranking junior to the Class A
Preferred Stock, (ii) declare or pay dividends on any stock ranking on a
parity with the Class A Preferred Stock, unless such dividends are paid
ratably to the holders of shares of Class A Preferred Stock, (iii) redeem,
purchase or otherwise acquire for consideration any share of stock ranking
junior to the shares of Class A Preferred Stock or (iv) redeem or purchase or
otherwise acquire for consideration any shares of Class A Preferred Stock, or
any shares of stock ranking on a parity with the Class A Preferred Stock,
except in accordance with an offer to all holders upon such terms as the Board
of Directors shall determine in good faith will result in a fair and equitable
treatment among the respective series or classes of stock. Holders of shares
of Class A Preferred Stock are entitled to preferential distributions upon
liquidation equal to $10.00 per share of Class A Preferred Stock plus
accumulated and unpaid dividends thereon. Holders of Class A Preferred Stock
have no preemptive, subscription or conversion rights. The Company is required
to
 
                                      72
<PAGE>
 
redeem all shares of Class A Preferred Stock outstanding as of December 31,
1999 at a redemption price equal to $10 per share plus an amount equal to all
accumulated and unpaid dividends thereon. WorldCom has agreed that no cash
dividends or distributions will be payable by the Company on the Class A
Preferred Stock owned by WorldCom, and the Class A Preferred Stock owned by
WorldCom will not be redeemed by the Company for cash, until a date that is
180 days following the Stated Maturity of the Notes. WorldCom is the sole
holder of shares of Class A Preferred Stock.
 
UNDESIGNATED STOCK
 
  The Company's Articles of Incorporation authorize the Company's Board of
Directors, without further shareholder action, to issue up to 9,900,000 shares
of Undesignated Stock in one or more series and to fix the voting rights,
liquidation preferences, dividend rights, repurchase rights, conversion
rights, redemption rights and terms, including sinking fund provisions, and
certain other rights and preferences of the Undesignated Stock. This authority
permits the Board of Directors to create out of the Undesignated Stock one or
more classes or series of preferred stock which may have rights, including
voting and conversion rights, that are different from or greater than the
rights of Common shareholders. Such preferred stock could adversely affect the
voting power or dividend rights of the holders of Common Stock and may have
the effect of delaying, deferring or preventing a change in control of the
Company.
 
CERTAIN OPTIONS, WARRANTS, CONVERTIBLE SUBORDINATED DEBT AND REGISTRATION
RIGHTS
 
  As of April 28, 1998, the Company had granted options to purchase a total of
10,889,900 shares of Common Stock at exercise prices ranging from $0.45 to
$8.00 per share, of which 6,216,504 are currently vested and exercisable and
the remainder vest and become exercisable at various times until 2008.
 
  In the first half of 1995, the Company issued a total of $250,000 aggregate
principal amount of 8% Convertible Subordinated Debentures due December 31,
1999, of which $100,000 aggregate principal amount is currently outstanding.
The Convertible Subordinated Debentures entitle the holder to convert at any
time prior to December 1, 1999, the date represented thereby into shares of
the Company's Common Stock at a conversion price ("Conversion Price") of $0.38
per share, subject to adjustment in the event of stock splits, reorganizations
or recapitalizations, and on a weighted-average basis in the event the Company
issues any Common Stock or security convertible into, or exercisable to
purchase, Common Stock at a price less than the then prevailing Conversion
Price. The Company may redeem the Convertible Subordinated Debentures at any
time commencing January 1, 1997 at 110% of the face amount, plus interest.
Except in certain limited circumstances, the holders of the Convertible
Subordinated Debentures have the right to include the shares of Common Stock
underlying the Convertible Subordinated Debentures in any registration
statement the Company may file in the future with respect to the Company's
Common Stock. The Convertible Subordinated Debentures also provide that the
Company may require the holders to convert the Convertible Subordinated
Debentures into Common Stock at any time the Company files a registration
statement. In June 1995, the holder of $100,000 of Convertible Subordinated
Debentures exercised the right to convert the Debenture into 263,160 shares of
the Company's Common Stock at the Conversion Price of $0.38 per share. In each
of July, 1996 and December 1997, the holder of $25,000 of Convertible
Subordinated Debentures exercised the right to convert the Debenture into
65,790 shares of the Company's Common Stock at the Conversion Price of $0.38
per share.
 
  Holders of 1,650,000 shares of the Company's Common Stock issued in a
private placement in June through August 1995 are entitled to the same
"demand" or "piggy back" registration rights that the Company may grant to any
other shareholder.
 
  From December 1995 through July 1996, the Company issued, in three series,
an aggregate of $5.6 million principal amount of subordinated promissory notes
(the "Bridge Financing"). In connection therewith, the Company issued to the
lenders of the Bridge Financing, for nominal consideration, warrants to
purchase a total of 5,600,000 shares of Common Stock and issued to the
placement agent in connection with such financing warrants to purchase 560,000
shares of Common Stock (collectively, the "Bridge Warrants"). The Bridge
 
                                      73

Warrants expire as follows: 1,760,000 on December 31, 2000, 1,100,000 on March
31, 2003 and 3,300,000 on June 30, 2003. The exercise price of the 1,760,000
warrants expiring on December 31, 2000 is $1.00 per share, and the initial
exercise price of the remaining 4,400,000 warrants is $1.50 per share, subject
to adjustment in the event of stock splits, reorganizations or
recapitalizations. Beginning on the date three years after the date of a
holder's Bridge Warrants, such holder of Bridge Warrants, or of Common Stock
acquired upon exercise of Bridge Warrants, may have the right to include such
Bridge Warrants or Common Stock in a registration statement the Company may
file after such date, subject to the right of the Company to exclude such
Bridge Warrants or Common Stock that are eligible for sale under an applicable
exemption from registration or if the managing underwriter reasonably deems
that the inclusion of such securities in such registration statement would
unreasonably interfere with the contemplated offering.
 
  In September 1996, the Company issued to WorldCom the WorldCom Convertible
Note. Interest on the WorldCom Convertible Note accrues at an annual rate of
10%, payable semi-annually, commencing with the first payment on March 30,
1997. At any time prior to September 30, 1999, WorldCom may convert the
principal amount of the WorldCom Convertible Note, in whole or in part, into
shares of Common Stock at a conversion price of $1.00 per share, subject to
adjustment in the event of stock splits, reorganizations or recapitalizations.
The Company may redeem the WorldCom Convertible Note, in whole or in part, at
any time on or after January 1, 1998 at its face amount plus accrued and
unpaid interest. Except in certain limited circumstances, WorldCom has the
right to include the shares of Common Stock underlying the WorldCom
Convertible Note in any registration statement filed by the Company under the
Securities Act. Notwithstanding the foregoing, if the managing underwriter of
such an offering believes in good faith that inclusion of all such shares
would reduce the number of shares to be offered or interfere with the
successful marketing of the shares to be offered, the number of such shares to
be included in such Registration Statement may be reduced; provided that any
such reduction shall be pro rata among all persons participating in the
offering. In addition, on one occasion only, at any time prior to September
17, 2001, WorldCom may request that the Company use its best efforts to
register or qualify the WorldCom Convertible Note or the shares issued upon
the conversion of the WorldCom Convertible Note under the Securities Act and
such state laws as are reasonably requested. Until the WorldCom Convertible
Note is paid in full or converted, the Company may not declare any dividends
on its Common Stock, except for certain stock splits in the form of a dividend
payable in shares of Common Stock.
 
  In March 1996, the Company entered into an arrangement with Leasing
Technologies International, Inc. ("LTI") pursuant to which LTI agreed to
provide the Company with up to $1,000,000 for the purchase of certain
equipment. See "Description of Certain Indebtedness." In partial consideration
for entering into this arrangement, the Company granted to LTI warrants to
purchase on or before April 30, 2003, up to 45,000 shares of the Company's
Common Stock at an exercise price of $1.50 per share, subject to adjustment in
the event of stock splits, reorganizations or recapitalizations. Beginning
April 26, 1999, LTI may have the right to include such warrants, or Common
Stock acquired upon exercise of such warrants, in a registration statement the
Company may file after such date.
 
  In connection with the execution of the WorldCom Agreement, in December
1996, the Company granted to WorldCom the WorldCom Warrants to purchase on or
before December 31, 2000, up to 20,787,500 shares of the Company's Common
Stock at an initial exercise price of $0.962 per share, subject to adjustment
in the event of stock splits, reorganizations or recapitalizations. See
"Certain Transactions and Relationships." The exercise price increased to
$0.982 per share on March 31, 1997, and thereafter will automatically increase
by the amount of $0.016 per share on the last day of each calendar quarterly,
subject to certain abatement provisions. Beginning December 16, 1999, WorldCom
has the right to include such WorldCom Warrants, or Common Stock acquired upon
exercise of such WorldCom Warrants, in a registration statement the Company
may file after such date, subject to the right of the Company to exclude such
WorldCom Warrants or Common Stock that are eligible for sale under an
applicable exemption from registration or if the managing underwriter
reasonably deems that the inclusion of such securities in such registration
statement would unreasonably interfere with the contemplated offering.

  In September 1997, the Company entered into the Revolving Credit Facility.
In consideration for WorldCom's guaranty of the Company's obligations under
the Revolving Credit Facility, the Company granted to WorldCom 8,396,170 Class
A warrants and 14,204,835 Class B warrants to purchase shares of the Company's
Common Stock at an exercise price of $3.90 per share, subject to adjustment in
the event of stock splits, reorganizations or recapitalizations and subject to
further adjustment after further consideration to determine the "fair market
value" as of September 15, 1997 of such warrants. The Class A warrants may be
exercised at any time on or before December 31, 2000. The Class B warrants
begin to vest after the 24th month of the Revolving Credit Facility depending
upon the outstanding balance under the Revolving Credit Facility at certain
times and whether certain qualified repayments are made. If the Company repays
all obligations under the Revolving Credit Facility prior to the 24th month
with certain qualified repayments no Class B warrants will vest. Beginning
September 26, 2000, WorldCom has the right to include such warrants, or shares
of Common Stock acquired upon exercise of such warrants, in a registration
statement filed by the Company after such date, subject to the right of the
Company to exclude such warrants or Common Stock that are eligible for sale
under an applicable exemption from registration or if the managing underwriter
reasonably deems that the inclusion of such securities in such registration
statement would unreasonably interfere with the contemplated offering.
 
  WorldCom has the option to convert (a) interest otherwise due on the
WorldCom Convertible Note and deferred pursuant to its agreement with the
Company, and (b) the interest accrued on the outstanding principal amount of
the WorldCom Subordinated Note from December 31, 2003 through the date such
amount is paid into shares of Common Stock at the per share price on the date
of such conversion.
   
  On March 5, 1998 the Company offered 208,530 Units (collectively, the
"Units"), each consisting of $1,000 principal amount at maturity of Original
Notes and three warrants (each, a "Warrant"). Each Warrant initially entitles
the holder to purchase 2.01 shares of Common Stock at an exercise price of
$0.01 per share, subject to adjustment. The Notes and Warrants will not be
separately transferable until the "Separability Date," which shall be the
earliest of: (i) September 1, 1998, (ii) the occurrence of certain specified
Warrant exercise events, (iii) the occurrence of an Event of Default (as
defined herein), (iv) the date on which a Shelf Registration Statement or an
Exchange Offer Registration Statement with respect to the Notes is declared
effective, (v) immediately prior to any redemption of Notes by the Company
from the net proceeds of an Initial Public Equity Offering (as defined
herein), (vi) immediately prior to the occurrence of a change of control, or
(vii) such earlier date as determined by Merrill Lynch & Co. (one of the
Initial Purchasers), in its sole discretion.     
   
  Pursuant to the terms of the 4-Sight Acquisition Agreement, 4-Sight's former
shareholders may receive an additional 625,000 shares of Common Stock if the
cumulative Non-US/Canada Revenues (defined below) in the period of three years
from the date of the sale and purchase of 4-Sight equal or exceed $50,000,000;
and a further 125,000 shares of Common Stock if the cumulative Non-US/Canada
Revenues in the period of three years from the date of the sale and purchase
of 4-Sight equal or exceed $70,000,000. For the purpose of the foregoing "Non-
US/Canada Revenues" shall mean the revenues attributable to customer sites
located outside the United States and Canada and receivable by the Company or
any of its subsidiaries.     
 
  The Company has obtained waivers from all persons that have, or arguably may
have, the right to include such securities in the Exchange Offer Registration
Statement or any Shelf Registration Statement to be filed for the benefit of
Noteholders.
 
PROVISIONS OF THE COMPANY'S ARTICLES OF INCORPORATION AND THE MINNESOTA
BUSINESS CORPORATION ACT
 
  The Company is a Minnesota corporation and is governed by the Minnesota
Business Corporation Act. The existence of authorized but unissued
Undesignated Stock, and certain provisions of Minnesota law, could have an
anti-takeover effect. These provisions are intended to provide management
flexibility to discourage an unsolicited takeover of the Company if the Board
determines that such a takeover is not in the best interests of the Company
and its shareholders. However, these provisions could have the effect of
discouraging some attempts to acquire the Company.
 
                                      75
<PAGE>
 
  Section 302A.671 of the Minnesota Business Corporation Act applies, with
certain exceptions, to any acquisition of voting stock of the Company (from a
person other than the Company, and other than in connection with certain
mergers and exchanges to which the Company is a party) resulting in the
beneficial ownership of 20 percent or more of the voting stock then
outstanding. Section 302A.671 requires approval of any such acquisitions by a
majority vote of the shareholders of the Company prior to its consummation. In
general, shares acquired in the absence of such approval are denied voting
rights and are redeemable at their then fair market value by the Company
within 30 days after the acquiring person has failed to give a timely
information statement to the Company or the date the shareholders voted not to
grant voting rights to the acquiring person's shares.
 
  Section 302A.673 of the Minnesota Business Corporation Act generally
prohibits any business combination by the Company, or any subsidiary of the
Company, with any shareholder which purchases 10% or more of the Company's
voting shares (an "interested shareholder") within four years following such
interested shareholder's share acquisition date, unless the business
combination is approved by a committee of all of the disinterested members of
the Board of Directors of the Company before the interested shareholder's
share acquisition date.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
  In March 1996, the Company entered into an equipment leasing arrangement
with LTI pursuant to which LTI agreed to lease up to $1.0 million of equipment
to the Company. In April 1996, the Company leased from LTI $245,396.60 of
computer hardware equipment for a term of 30 months, commencing May 1, 1996,
at a monthly rental of $9,480, subject to certain adjustments.
   
  In September 1996, the Company issued to WorldCom the WorldCom Convertible
Note due September 30, 1999 in the principal amount of $5.0 million. Interest
on the WorldCom Convertible Note accrues at an annual rate of 10%, payable
semi-annually, commencing with the first payment on March 30, 1997. The
WorldCom Convertible Note is subordinate to the Notes; WorldCom has agreed to
defer all cash payments in respect of the WorldCom Convertible Note until a
date that is 180 days following the Stated Maturity of the Notes. At any time
prior to September 30, 1999, WorldCom may convert the principal amount of the
WorldCom Convertible Note into shares of Common Stock at a conversion price of
$1.00 per share, subject to adjustment in the event of stock splits,
reorganizations or recapitalizations. Payment of principal and interest on the
WorldCom Convertible Note is subordinated to existing and future obligations
of the Company for money borrowed from bank, trust, insurance or other
financial institutions. The Company may redeem the WorldCom Convertible Note
at any time commencing January 1, 1998 at its face amount plus accrued and
unpaid interest. The shares of Common Stock underlying the Convertible Note
are subject to certain registration rights. See "Description of the Company's
Securities--Certain Options, Warrants, Convertible Subordinated Debt and
Registration Rights."     
   
  In December 1996, the Company issued to WorldCom the WorldCom Subordinated
Note due December 31, 2003 in the principal amount of $28.5 million, of which
$20.4 aggregate principal amount was outstanding as of December 31, 1997. The
WorldCom Subordinated Note accrues interest at an annual rate of 7%, payable
semi-annually, commencing March 31, 1997. The WorldCom Subordinated Note is
subordinate to the Notes; WorldCom has agreed to defer all cash payments in
respect of the WorldCom Subordinated Note until a date that is 180 days
following the Stated Maturity of the Notes. WorldCom will, upon the request of
the Company, make additional disbursements under the WorldCom Subordinated
Note in an amount up to $332,500 not more frequently than once each quarter,
commencing March 31, 1997. Payment of principal and interest on the WorldCom
Subordinated Note is subordinated to existing and future obligations of the
Company for money borrowed from bank, trust, insurance or other financial
institutions.     
 
  In September 1997, the Company entered into the Revolving Credit Facility
with The First National Bank of Chicago ("FNBC"), an affiliate of First
Chicago Capital Markets, Inc., one of the Initial Purchasers. At the Company's
election, the interest rate per annum applicable to the Revolving Credit
Facility is a fluctuating rate of interest measured by reference to either:
(i) the adjusted London inter-bank offered rate ("LIBOR") plus 55 basis points
(the "Eurodollar Rate") or (ii) the greater of the Federal Funds Effective
Rate or the corporate base rate announced by FNBC plus 50 basis points (the
"Floating Rate") . On March 31, 1998, the Eurodollar Rate was equal to 6.2375%
per annum and the Floating Rate was equal to 8.5% per annum. The aggregate
principal amount outstanding under the Revolving Credit Facility as of March
31, 1998 was $0. The Revolving Credit Facility matures and becomes payable in
full on September 26, 2000. Subject to the written authorization of WorldCom,
as guarantor of the obligations of the Company under the Revolving Credit
Facility, the Company may from time to time make additional draws under the
Revolving Credit Facility up to an aggregate of $25.0 million outstanding at
any one time.
 
  The Company has outstanding the following items of indebtedness relating to
the purchase of certain equipment and the licensing of certain proprietary
software by the Company:
 
  (i) An installment note in favor of FINOVA Technology Finance, Inc.
("FINOVA") bearing monthly payments of $43,324 and an additional final payment
of $241,955, due April 2001.
 
  (ii) An installment note in favor of FINOVA bearing monthly payments of
$90,995 and an additional final payment of $509,052, due May 2001.

Corporation ("Transamerica") bearing monthly payments of $46,043 and an
additional final payment of $206,552, due May 2001.
 
  (iv) An installment note in favor of Transamerica bearing monthly payments
of $41,692 and an additional final payment of $187,349, due May 2001.

                           DESCRIPTION OF THE NOTES
 
  The Original Notes are, and the Exchange Notes will be, issued under an
Indenture (the "Indenture") to be dated as of March 5, 1998, between WAM!NET
Inc. (the "Issuer") and U.S. Bank Trust National Association (f/k/a First
Trust National Association), as Trustee, a copy of which has been filed as an
exhibit to the Exchange Offer Registration Statement. Upon the issuance of the
Exchange Notes, if any, or the effectiveness of a Shelf Registration Statement
with respect to the Notes, the Indenture will be subject to and governed by
the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The
following summary of certain provisions of the Indenture does not purport to
be complete and is subject to, and is qualified in its entirety by reference
to, the Trust Indenture Act and to all of the provisions of the Indenture,
including the definitions of certain terms therein and those terms made a part
of the Indenture by reference to the Trust Indenture Act, as in effect on the
date of the Indenture. The definitions of certain capitalized terms used in
the following summary are set forth below under "--Certain Definitions."
 
GENERAL
   
  The Original Notes are, and the Exchange Notes will be, issued only in fully
registered form without coupons, in denominations of $1,000 principal amount
and integral multiples thereof. Principal of, premium, if any, and interest on
the Notes are payable, and the Notes are exchangeable and transferable, at the
office or agency of the Issuer in the City of New York maintained for such
purposes (which initially will be the corporate trust office of the Trustee).
See "Book-Entry; Delivery and Form." No service charge will be made for any
registration of transfer, exchange or redemption of the Notes, except in
certain circumstances for any tax or other governmental charge that may be
imposed in connection therewith.     
 
MATURITY, INTEREST AND PRINCIPAL
 
  The Original Notes are, and the Exchange Notes will be, general unsecured
obligations of the Issuer, limited to $208,530,000 aggregate principal amount
at maturity, and will mature on March 1, 2005. The Notes will not bear cash
interest prior to March 1, 2002. See "Certain Federal Income Tax
Considerations." Commencing on September 1, 2002, interest on the Notes will
be payable, in cash, at a rate of 13 1/4% per annum, semi-annually in arrears
on each March 1 and September 1 to registered holders of Notes on the February
15 or August 15, as the case may be, immediately preceding such interest
payment date. Interest on the Notes will accrue from the most recent interest
payment date to which interest has been paid or duly provided for or, if no
interest has been paid or duly provided for, from March 1, 2002. Based on the
foregoing, the yield to maturity of each Note will be 14.59% (computed on a
semi-annual bond equivalent basis). Interest will be computed on the basis of
a 360-day year of twelve 30-day months. If the Issuer defaults on any payment
of principal (whether at maturity, upon redemption or otherwise), cash
interest will continue to accrue and, to the extent permitted by law, cash
interest will accrue on overdue installments of interest at the rate of
interest borne by the Notes.
   
  As discussed under "Exchange Offer" and "Note Registration Rights," pursuant
to the Registration Rights Agreement, the Issuer has agreed, for the benefit
of the holders of Notes, to effect at its expense a registered exchange offer
under the Securities Act to exchange the Notes for Exchange Notes. The failure
to comply with such agreement in certain respects may result in the Issuer
paying cash interest on the Notes as liquidated damages.     
 
REDEMPTION
 
  Optional Redemption. The Notes are redeemable, at the option of the Issuer,
in whole or in part, on or after March 1, 2002, upon not less than 30 nor more
than 60 days' written notice at the redemption prices (expressed as
percentages of principal amount at maturity) set forth below, plus accrued and
unpaid interest thereon, if any, to the applicable redemption date, if
redeemed during the twelve-month period beginning on March 1 of each of the
years indicated below:
 
<TABLE>
<CAPTION>
            YEAR                               PERCENTAGE
            ----                               ----------
            <S>                                <C>
            2002..............................  106.6250%
            2003..............................  103.3125%
            2004..............................  100.0000%
</TABLE>
 
 
                                      79
<PAGE>
 
  In addition, at any time on or prior to March 1, 2001, the Issuer may, other
than in any circumstances resulting in a Change of Control, redeem, at its
option, up to a maximum of 25% of the originally-issued aggregate principal
amount at maturity of Notes at a redemption price (determined at the
redemption date) equal to 113.25% of the Accreted Value of the Notes so
redeemed, with the net cash proceeds of an Initial Public Equity Offering
resulting in gross cash proceeds to the Issuer of at least $35.0 million in
the aggregate; provided that not less than 75% of the originally-issued
aggregate principal amount at maturity of Notes is outstanding immediately
following such redemption. Any such redemption must be effected upon not less
than 30 nor more than 60 days' notice given within 30 days after the
consummation of the Initial Public Equity Offering.
 
  Mandatory Redemption. The Issuer will not be required to repurchase the
Notes or make any mandatory redemption or sinking fund payments in respect of
the Notes. However, (i) following the occurrence of a Change of Control the
Issuer will be required to make an offer to purchase all outstanding Notes at
a price equal to 101% of the Accreted Value thereof as of the date of purchase
and (ii) following the occurrence of an Asset Sale the Issuer may be obligated
to make an offer to purchase all or a portion of the outstanding Notes at a
price equal to 100% of the Accreted Value thereof as of the date of purchase,
in each case plus accrued and unpaid interest, if any, to the date of
purchase. See "--Certain Covenants--Change of Control" and "--Disposition of
Proceeds of Asset Sales," respectively.
 
  Selection; Effect of Redemption Notice. In the case of a partial redemption,
selection of the Notes for redemption will be made pro rata, by lot or such
other method as the Trustee in its sole discretion deems appropriate and just;
provided that any redemption pursuant to the provisions relating to
redemptions from the proceeds of one or more Public Equity Offerings or sales
to one or more Strategic Equity Investors shall be made on a pro rata basis or
on as nearly a pro rata basis as practicable (subject to DTC procedures). No
Notes of a principal amount at maturity of $1,000 or less shall be redeemed in
part. Notice of redemption shall be mailed by first-class mail at least 30 but
not more than 60 days before the redemption date to each holder of Notes to be
redeemed at its registered address. If any Note is to be redeemed in part
only, the notice of redemption that relates to such Note shall state the
portion of the principal amount thereof to be redeemed. A new Note in a
principal amount at maturity equal to the unredeemed portion thereof will be
issued in the name of the holder thereof upon surrender for cancellation of
the original Note. Upon giving of a redemption notice, interest on Notes
called for redemption will cease to accrue from and after the date fixed for
redemption (unless the Issuer defaults in providing the funds for such
redemption) and such Notes will cease to be outstanding.
 
RANKING
   
  The Indebtedness of the Issuer evidenced by the Notes ranks senior in right
of payment to all Subordinated Indebtedness of the Issuer and pari passu in
right of payment with all existing and future unsecured and unsubordinated
Indebtedness of the Issuer. The Notes are effectively subordinated in right of
payment to all secured Indebtedness of the Issuer. Assuming the Notes had been
issued on March 31, 1998, and after giving effect to the application of the
estimated net proceeds thereof, the Issuer would have had outstanding at that
date approximately $10.4 million of secured Indebtedness, which would have
been effectively senior to the Notes, no Indebtedness which would have ranked
pari passu with the Notes and $25.9 million of Indebtedness which would have
been subordinated in right of payment to the Notes.     
 
  Although the Indenture contains limitations on the amount of additional
Indebtedness which the Issuer or its Restricted Subsidiaries may incur, under
certain circumstances the amount of such Indebtedness could be substantial,
and the Indenture does not limit the amount of secured Permitted Equipment
Financing that may be incurred by the Issuer. See "--Certain Covenants--
Limitation on Additional Indebtedness" below. If the Issuer becomes insolvent
or is liquidated, or if payment under the any secured Permitted Equipment
Financing or other secured credit facility is accelerated, the lenders under
the Permitted Equipment Financing or such other facility would be entitled to
exercise the remedies available to a secured lender under applicable law
pursuant to the terms of the applicable financing agreements. Accordingly, any
claims of such lenders with respect to assets secured in their favor will be
prior to any claims of the holders of the Notes with respect to such assets.
 
 
                                      80
<PAGE>
 
   
  The Notes are guaranteed on an unsecured basis by all Material Restricted
Subsidiaries of the Issuer, which guarantees may be released under certain
circumstances; provided, however, that a Material Restricted Subsidiary that
is a Foreign Subsidiary shall not become a Subsidiary Guarantor if by doing so
it would violate applicable law of its jurisdiction of organization or
incorporation. As of the Issue Date and as of the date hereof, the Issuer did
not have any Material Restricted Subsidiaries that are Subsidiary Guarantors.
No other Subsidiary of the Issuer will be required to guarantee the
Indebtedness represented by the Notes, except under the circumstances
described under "--Certain Covenants--Issuance of Guarantees by Certain
Restricted Subsidiaries; Release of Guarantees'' below. As of the date hereof,
the Subsidiaries of the Issuer have no Indebtedness.     
 
CERTAIN COVENANTS
 
  Set forth below are certain covenants that are contained in the Indenture.
 
  Limitation on Additional Indebtedness. The Indenture provides that the
Issuer will not, and will not permit any Restricted Subsidiary to, directly or
indirectly, create, incur, assume, issue, guarantee or in any manner become
directly or indirectly liable for or with respect to, contingently or
otherwise, the payment of (collectively, to "incur") any Indebtedness
(including any Acquired Indebtedness), except for Permitted Indebtedness
(including Acquired Indebtedness to the extent it would constitute Permitted
Indebtedness); provided (i) the Issuer will be permitted to incur Indebtedness
(including Acquired Indebtedness) and (ii) a Restricted Subsidiary will be
permitted to incur Acquired Indebtedness, if, in either case, after giving pro
forma effect to such incurrence (including the application of the net proceeds
therefrom), the Indebtedness to EBITDA Ratio would be less than or equal to 5
to 1.
 
  Indebtedness of any person or any of its Subsidiaries existing at the time
such Person becomes a Restricted Subsidiary (or is merged into or consolidated
with the Issuer or any Restricted Subsidiary), whether or not such
Indebtedness was incurred in connection with, or in contemplation of, such
person becoming a Restricted Subsidiary (or being merged into or consolidated
with the Issuer or any Restricted Subsidiary) shall be deemed incurred at the
time any such person becomes a Restricted Subsidiary or merges into or
consolidates with the Issuer or any Restricted Subsidiary.
 
  For purposes of determining compliance with this covenant, in the event that
an item of Indebtedness may be incurred by meeting the criteria of one or more
items of Permitted Indebtedness, the Issuer may, in its sole discretion,
classify and divide such item of Indebtedness among more than one of such
items of Permitted Indebtedness.
 
  Limitation on Restricted Payments. The Indenture provides that the Issuer
will not, and will not permit any of the Restricted Subsidiaries to, make,
directly or indirectly, any Restricted Payment unless:
 
    (i) no Default shall have occurred and be continuing at the time of or
  upon giving effect to such Restricted Payment;
 
    (ii) immediately after giving effect to such Restricted Payment, the
  Issuer would be able to incur $1.00 of Indebtedness under the proviso of
  the covenant "--Limitation on Additional Indebtedness"; and
 
    (iii) immediately after giving effect to such Restricted Payment, the
  aggregate amount of all Restricted Payments declared or made on or after
  the Issue Date does not exceed an amount equal to the sum of, without
  duplication, (a) 50% of the Consolidated Net Income accrued on a cumulative
  basis during the period beginning on the first day of the first fiscal
  quarter immediately following the Issue Date and ending on the last day of
  the fiscal quarter of the Issuer immediately preceding the date of such
  proposed Restricted Payment (or, if such cumulative Consolidated Net Income
  of the Issuer for such period is a deficit, minus 100% of such deficit) for
  which financial statements have been provided pursuant to "--Reports''
  below, in any event determined by excluding income resulting from transfers
  of assets by the Issuer or a Restricted Subsidiary to an Unrestricted
  Subsidiary, plus (b) the aggregate net cash proceeds received by the Issuer
  either (x) as capital contributions to the Issuer after the Issue Date or
  (y) from the issuance and sale of its Capital Stock (other than
  Disqualified Stock) or options, warrants or other rights to acquire its
  Capital Stock
 
                                      81

  (other than Disqualified Stock) (exclusive of any convertible Indebtedness
  or any options, warrants or other rights that are redeemable at the option
  of the holder, or are required to be redeemed, prior to the Stated Maturity
  of the Notes), in each case on or after the Issue Date to a person who is
  not a Subsidiary of the Issuer, plus (c) the aggregate net proceeds
  received by the Issuer from the issuance (other than to a Subsidiary of the
  Issuer) on or after the Issue Date of its Capital Stock (other than
  Disqualified Stock) upon the conversion of, or in exchange for,
  Indebtedness of the Issuer or upon the exercise of options, warrants or
  other rights of Issuer, plus (d) in the case of the disposition or
  repayment (in whole or in part) of any Investment constituting a Restricted
  Payment made after the Issue Date, an amount equal to the lesser of the
  return of capital with respect to the applicable portion of such Investment
  and the cost of the applicable portion of such Investment, in either case,
  less the cost of the disposition of such Investment, plus (e) in the case
  of any Revocation with respect to a Subsidiary of the Issuer that was made
  subject to a Designation after the Issue Date, an amount equal to the
  lesser of the Designation Amount with respect to such Subsidiary or the
  Fair Market Value of the Investment of the Issuer and the Restricted
  Subsidiaries in such Subsidiary at the time of Revocation, minus (f) 50% of
  the principal amount of any Indebtedness incurred pursuant to clause (g) of
  the definition of "Permitted Indebtedness," minus (g) the greater of (x) $0
  and (y) the Designation Amount (measured as of the date of Designation)
  with respect to any Subsidiary that has been designated as an Unrestricted
  Subsidiary in accordance with "--Limitation on Designations of Unrestricted
  Subsidiaries'' below. For purposes of the preceding clauses (b) (y) and
  (c), as applicable, (A) the value of the aggregate net proceeds received by
  the Issuer upon the issuance of Capital Stock either upon the conversion of
  convertible Indebtedness or in exchange for outstanding Indebtedness or
  upon the exercise of options, warrants or rights will be the net cash
  proceeds received upon the issuance of such Indebtedness, options, warrants
  or rights plus the incremental amount received, if any, by the Issuer upon
  the conversion, exchange or exercise thereof, (B) there shall be excluded
  in all cases any issuance and sale of Capital Stock financed, directly or
  indirectly, using funds (I) borrowed from the Issuer or any Subsidiary
  until and to the extent such borrowing is repaid or (II) contributed,
  extended, guaranteed or advanced by the Issuer or any Subsidiary
  (including, without limitation, in respect of any employee stock ownership
  or benefit plan) and (C) there shall be excluded in all cases any issuance
  and sale of Capital Stock in an Initial Public Equity Offering to the
  extent the net cash proceeds are used, prior to March 1, 2001, to redeem
  Notes as described under "--Redemption--Optional Redemption." The Issuer
  may not redeem Notes as described under "--Redemption--Optional
  Redemption'' from net cash proceeds received by the Issuer from the
  issuance on or after the Issue Date of its Capital Stock if such net cash
  proceeds have ever been included in a determination of the amount of
  Restricted Payments that may be made by the Issuer pursuant to this
  covenant.
 
  For purposes of determining the amount expended for Restricted Payments,
cash distributed shall be valued at the face amount thereof and property other
than cash shall be valued at its Fair Market Value.
 
  The provisions of this covenant shall not prohibit the following (each of
which shall be given independent effect): (i) the payment of any dividend or
other distribution within 60 days after the date of declaration thereof if at
such date of declaration such payment would be permitted by the provisions of
the Indenture; (ii) the purchase, redemption, retirement or other acquisition
of any shares of Capital Stock of the Issuer in exchange for, or out of the
net cash proceeds of the substantially concurrent issue and sale (other than
to a Subsidiary of the Issuer) of, shares of Capital Stock of the Issuer
(other than Disqualified Stock); provided that any such net cash proceeds are
excluded from clause (iii) (b) of the second preceding paragraph; (iii) so
long as no Default shall have occurred and be continuing, the purchase,
redemption, retirement, defeasance or other acquisition of Subordinated
Indebtedness made by exchange for, or out of the net cash proceeds of, a
substantially concurrent issue and sale (other than to a Subsidiary of the
Issuer) of (x) Capital Stock (other than Disqualified Stock) of the Issuer or
(y) other Subordinated Indebtedness to the extent that its stated maturity for
the payment of principal thereof is not prior to the 180th day after the final
stated maturity of the Notes; provided that any such net cash proceeds are
excluded from clause (iii) (b) of the second preceding paragraph; (iv) so long
as no Default shall have occurred and be continuing, purchases or redemptions
of Capital Stock (including cash settlements of stock options) held by
employees, officers or directors upon or following termination of their
employment with the
 
                                      82
<PAGE>
 
Issuer or one of its Subsidiaries; provided that payments shall not exceed
$750,000 in any fiscal year in the aggregate or $3.0 million in the aggregate
during the term of the Notes; (v) so long as no Default shall have occurred
and be continuing, Investments in Unrestricted Subsidiaries to the extent
reasonably promptly made with the proceeds of (x) a capital contribution to
the Issuer or (y) an issue or sale of Capital Stock (other than Disqualified
Capital Stock) of the Issuer (other than to a Subsidiary); provided that any
such net cash proceeds are excluded from clause (iii) (b) of the second
preceding paragraph; and (vi) so long as no Default shall have occurred and be
continuing, Investments in (x) joint ventures formed to engage in the Digital
Network Business and (y) other persons principally engaged in the Digital
Network Business; provided that no more than $12.5 million of Investments made
pursuant to this clause (vi) shall be outstanding at any time.
 
  In determining the amount of Restricted Payments permissible under this
covenant, amounts expended pursuant to clauses (i), (iv) and (vi) above shall
be included, without duplication, as Restricted Payments.
 
  Limitation on Liens Securing Certain Indebtedness. The Indenture provides
that the Issuer will not, and will not permit any Restricted Subsidiary to,
create, incur, assume or suffer to exist any Liens of any kind against or upon
any of the property or assets of the Issuer or any Restricted Subsidiary,
whether now owned or hereafter acquired, or any proceeds therefrom, which
secure either (x) Subordinated Indebtedness unless the Notes are secured by a
Lien on such property, assets or proceeds that is senior in priority to the
Liens securing such Subordinated Indebtedness or (y) Indebtedness of (A) the
Issuer or any Subsidiary Guarantor that is not Subordinated Indebtedness or
(B) any Restricted Subsidiary (other than a Subsidiary Guarantor), unless the
Notes are equally and ratably secured with the Liens securing such other
Indebtedness, except, in the case of this clause (y), Permitted Liens.
   
  Issuance of Guarantees by Certain Restricted Subsidiaries; Release of
Guarantees. The Indenture provides that each Material Restricted Subsidiary
will become a guarantor of the Notes (each a "Subsidiary Guarantor" and
collectively the "Subsidiary Guarantors"); provided, that a Material
Restricted Subsidiary that is a Foreign Subsidiary shall not become a
Subsidiary Guarantor if by doing so it would violate applicable law of its
jurisdiction of organization or incorporation. Each Subsidiary Guarantor will
fully and unconditionally guarantee (collectively, the "Subsidiary
Guarantees"), jointly and severally, on a senior unsecured basis to each
holder of a Note the due and punctual payment of the principal of, premium, if
any, and interest on, and all other amounts owing in respect of such Note and
under the Indenture. A Subsidiary may become a Material Restricted Subsidiary
and, in accordance with the terms of the Indenture, a Subsidiary Guarantor, at
any time while the Notes are outstanding. Each Subsidiary Guarantor will
execute a supplemental indenture evidencing its Subsidiary Guarantee in the
form attached to the Indenture. The Company will amend the Registration
Statement and attach a Supplemental Indenture should a subsidiary become a
Subsidiary Guarantor during the Exchange Offer.     
 
  The Issuer will not permit any Restricted Subsidiary that is not a
Subsidiary Guarantor, directly or indirectly, to Guarantee any Indebtedness of
any person unless, in each case, such Restricted Subsidiary simultaneously
executes and delivers to the Trustee a supplemental indenture pursuant to
which such Restricted Subsidiary shall guarantee the full and punctual payment
of all obligations of the Issuer under the Indenture and the Notes on the same
terms and conditions as the Subsidiary Guarantees by the Subsidiary
Guarantors.
 
  Pursuant to each Subsidiary Guarantee, if the Issuer defaults in payment of
any amount owing in respect of the Notes or the Indenture, the Subsidiary
Guarantor will be obligated to duly and punctually pay the same. Pursuant to
the terms of the Indenture, each of the Subsidiary Guarantors will agree that
its obligations under its Subsidiary Guarantee will be unconditional,
irrespective of the validity, regularity or enforceability of the Notes or the
Indenture, the absence of any action to enforce the same or any other
circumstance which might otherwise constitute a legal or equitable discharge
of defense of a guarantor.
 
  Upon (i) any sale or disposition (by merger or otherwise) of any Subsidiary
Guarantor by the Issuer, or a Restricted Subsidiary of the Issuer, to any
person that is not an Affiliate of the Issuer or any of its Subsidiaries (and
which is otherwise in compliance with the terms of the Indenture) as a result
of which such Subsidiary
 
                                      83
<PAGE>
 
Guarantor ceases to be a Restricted Subsidiary of the Issuer or (ii) the
Designation of any Restricted Subsidiary that is a Subsidiary Guarantor as an
Unrestricted Subsidiary in compliance with the covenant "--Limitation on
Designations of Unrestricted Subsidiaries," such Subsidiary Guarantor will be
deemed to be automatically and unconditionally released from all obligations
under its Subsidiary Guarantee.
 
  Change of Control. Upon the occurrence of a Change of Control (the date of
such occurrence being the "Change of Control Date"), the Issuer shall make an
offer to purchase (the "Change of Control Offer"), on a business day (the
"Change of Control Payment Date") not later than 60 days following the Change
of Control Date, all Notes then outstanding at a purchase price equal to 101%
of the Accreted Value thereof as of any Change of Control Payment Date, plus
accrued and unpaid interest thereon, if any, to such Change of Control Payment
Date. Notice of a Change of Control Offer shall be given to holders of Notes,
not less than 25 days nor more than 45 days before the Change of Control
Payment Date. The Change of Control Offer is required to remain open for at
least 20 business days and until the close of business on the Change of
Control Payment Date.
 
  Except as described above with respect to a Change of Control, the Indenture
does not contain provisions that permit the holders of the Notes to require
that the Issuer repurchase or redeem the Notes in the event of a takeover,
recapitalization or similar transaction which may be highly leveraged.
   
  If a Change of Control Offer is made, there can be no assurance that the
Issuer will have available funds sufficient to pay for all of the Notes that
might be delivered by holders of Notes seeking to accept the Change of Control
Offer. The Issuer's obligation to make a Change of Control Offer following a
Change of Control shall be satisfied if a third party makes the Change of
Control Offer in the manner, at the times and otherwise in compliance with the
requirements applicable to a Change of Control Offer made by the Issuer and
purchases all Notes validly tendered and not withdrawn under such Change of
Control Offer. In addition, a Change in Control could result in the
acceleration of existing or future indebtedness of the Company that is senior
to the Notes, and, as such, may adversely affect the ability of the Company to
repay the Notes. See "Risk Factors--Risks Associated with a Change of
Control."     
 
  If the Issuer is required to make a Change of Control Offer, the Issuer will
comply with all applicable tender offer laws and regulations, including, to
the extent applicable, Section 14(e) and Rule 14e-1 under the Exchange Act,
and any other applicable securities laws and regulations.
 
  Limitation on Dividends and Other Payment Restrictions Affecting Restricted
Subsidiaries. The Indenture provides that the Issuer will not, and will not
permit any Restricted Subsidiary to, directly or indirectly, create or
otherwise enter into or cause to become effective any consensual encumbrance
or consensual restriction of any kind on the ability of any Restricted
Subsidiary to pay dividends, in cash or otherwise, or make any other
distributions on its Capital Stock or any other interest or participation in,
or measured by, its profits to the extent owned by the Issuer or any
Restricted Subsidiary, except for (i) any encumbrance or restriction in
existence on the Issue Date, (ii) customary non-assignment provisions, (iii)
any encumbrances or restriction pertaining to an asset subject to a Lien to
the extent set forth in the security documentation governing such Lien, (iv)
any encumbrance or restriction applicable to a Restricted Subsidiary at the
time that it becomes a Restricted Subsidiary that is not created in
contemplation thereof, (v) any encumbrance or restriction existing under any
agreement that refinances or replaces an agreement containing a restriction
permitted by clause (iv) above; provided that the terms and conditions of any
such encumbrance or restriction are not materially less favorable to the
holders of Notes than those under or pursuant to the agreement being replaced
or the agreement evidencing the Indebtedness refinanced, (vi) any encumbrance
or restriction imposed upon a Restricted Subsidiary pursuant to an agreement
which has been entered into for the sale or disposition of all or
substantially all of the Capital Stock or assets of such Restricted Subsidiary
or any Asset Sale to the extent limited to the Capital Stock or assets in
question, (vii) any customary encumbrance or restriction applicable to a
Restricted Subsidiary that is contained in an agreement or instrument
governing or relating to Indebtedness contained in any Debt Securities;
provided that the terms and conditions of any such encumbrance or restriction
are no more restrictive than those contained in the Indenture; and provided
further, that the provisions of such agreement or instrument permit the
payment
 
                                      84
<PAGE>
 
of interest and principal and mandatory repurchases pursuant to the terms of
the Indenture and the Notes and other Indebtedness (other than Subordinated
Indebtedness) that is solely an obligation of the Issuer; and (viii) any
customary encumbrance or restriction contained in (x) a Permitted Credit
Facility or (y) a pledge agreement applicable to Capital Stock of a Restricted
Subsidiary that is Foreign Subsidiary pledged to secure Indebtedness incurred
pursuant to Permitted Equipment Financing; provided that the provisions of any
such agreement do not restrict the payment of cash dividends or distributions
to the Issuer or any Restricted Subsidiary prior to the occurrence of a
default or an event of default under such Permitted Credit Facility or
Permitted Equipment Financing.
 
  Disposition of Proceeds of Asset Sales. The Indenture provides that the
Issuer will not, and will not permit any Restricted Subsidiary to, make any
Asset Sale unless (a) the Issuer or such Restricted Subsidiary, as the case
may be, receives consideration at the time of such Asset Sale at least equal
to the Fair Market Value of the shares or assets sold or otherwise disposed of
and (b) at least 80% of such consideration consists of cash or Cash
Equivalents; provided that the following shall be treated as cash for purposes
of this covenant: (x) the amount of any Indebtedness (other than Subordinated
Indebtedness) of the Issuer or any Restricted Subsidiary that is actually
assumed by the transferee in such Asset Sale and from which Issuer and the
Restricted Subsidiaries are fully released and (y) the amount of any notes or
other obligations that within 30 days of receipt are converted into cash (to
the extent of the cash (after payment of any costs of disposition) so
received). The Issuer or the applicable Restricted Subsidiary, as the case may
be, may (i) apply the Net Cash Proceeds from such Asset Sale within 365 days
of the receipt thereof to repay secured Indebtedness incurred pursuant to a
Permitted Credit Facility, (ii) apply such Net Cash Proceeds within 365 days
of the receipt thereof to repay Indebtedness of any Restricted Subsidiary that
is not a Subsidiary Guarantor and permanently reduce the amount of the
commitments thereunder by the amount of the Indebtedness so repaid, and/or
(iii) apply such Net Cash Proceeds within 365 days of the receipt thereof to
the an investment in properties and assets that will be used in a Digital
Network Business of the Company or any Restricted Subsidiary (or in Capital
Stock of any person that will become a Restricted Subsidiary as a result of
such investment if all or substantially all of the properties and assets of
such person are used in a Digital Network Business).
 
  To the extent all or part of the Net Cash Proceeds of any Asset Sale are not
applied within 365 days of such Asset Sale as described in clause (i), (ii) or
(iii) of the preceding paragraph (such Net Cash Proceeds, the "Unutilized Net
Cash Proceeds"), the Issuer shall, within 20 days after such 365th day, make
an offer to purchase (an "Asset Sale Offer") all outstanding Notes up to a
maximum Accreted Value (expressed as a multiple of $1,000) equal to the Note
Pro Rata Share of Unutilized Net Cash Proceeds, at a purchase price in cash
equal to 100% of the Accreted Value thereof as of any purchase date, plus
accrued and unpaid interest, if any, to such purchase date; provided, however,
that an Asset Sale Offer may be deferred by the Issuer until there are
Unutilized Net Cash Proceeds equal to at least $5.0 million, at which time the
entire amount of such Unutilized Net Cash Proceeds (and not just the amount in
excess of $5.0 million) shall be applied as required pursuant to this
paragraph.
 
  In the event that any other Indebtedness of the Issuer which ranks pari
passu with the Notes (the "Other Indebtedness") requires that an offer to
repurchase such Indebtedness be made upon the consummation of an Asset Sale,
the Issuer may apply the Unutilized Net Cash Proceeds otherwise required to be
applied to an Asset Sale Offer to offer to purchase such Other Indebtedness
and to an Asset Sale Offer so long as the amount of such Unutilized Net Cash
Proceeds applied to repurchase the Notes is not less than the Note Pro Rata
Share of Unutilized Net Cash Proceeds. Any offer to purchase such Other
Indebtedness shall be made at the same time as the Asset Sale Offer, and the
purchase date in respect of any such offer to purchase and the Asset Sale
Offer shall occur on the same day.
 
  For purposes of this covenant, "Note Pro Rata Share of Unutilized Net Cash
Proceeds" means the amount of the Unutilized Net Cash Proceeds equal to the
product of (x) the Unutilized Net Cash Proceeds and (y) a fraction, the
numerator of which is the Accreted Value of all Notes validly tendered and not
withdrawn pursuant to an Asset Sale Offer related to such Unutilized Net Cash
Proceeds (the "Note Amount") and the denominator of which is the sum of the
Note Amount and the lesser of the aggregate principal face amount or accreted
value
 
                                      85
<PAGE>
 
as of the relevant purchase date of all Other Indebtedness validly tendered
and not withdrawn pursuant to a concurrent offer to purchase such Other
Indebtedness made at the time of such Asset Sale Offer.
 
  Each Asset Sale Offer shall remain open for a period of 20 business days or
such longer period as may be required by law. To the extent that the Accreted
Value of Notes validly tendered and not withdrawn pursuant to an Asset Sale
Offer is less than the Note Pro Rata Share of Unutilized Net Cash Proceeds,
the Issuer or any Restricted Subsidiary may use such deficiency for general
corporate purposes. If the Accreted Value of Notes validly tendered and not
withdrawn by holders thereof exceeds the amount of Notes which can be
purchased with the Unutilized Net Cash Proceeds, Notes to be purchased will be
selected on a pro rata basis. Upon completion of an Asset Sale Offer, the
amount of Unutilized Net Cash Proceeds shall be reset to zero.
 
  If the Issuer is required to make an Asset Sale Offer, the Issuer will
comply with all applicable tender offer rules, including, to the extent
applicable, Section 14(e) and Rule 14e-1 under the Exchange Act, and any other
applicable securities laws and regulations.
 
  Limitation on Issuances and Sales of Capital Stock of Restricted
Subsidiaries. The Indenture provides that the Issuer will not sell, and will
not permit any Restricted Subsidiary, directly or indirectly, to issue or
sell, any shares of Capital Stock (or any options, warrants or other rights to
purchase such Capital Stock) of a Restricted Subsidiary, except (i) to the
Issuer or a Wholly Owned Restricted Subsidiary, (ii) to directors as director
qualifying shares, but only to the extent required under applicable law, (iii)
the Issuer or a Restricted Subsidiary may pledge Capital Stock of a Restricted
Subsidiary that is a Foreign Subsidiary to the extent and in the manner
permitted under clause (g) of the definition of "Permitted Liens;" (iv) if,
immediately after giving effect to such issuance or sale, such Restricted
Subsidiary would no longer constitute a Restricted Subsidiary or (v) if the
covenant "--Disposition of Proceeds of Asset Sales" is complied with.
 
  Limitation on Transactions with Affiliates. The Indenture provides that the
Issuer will not, and will not permit, cause or suffer any Restricted
Subsidiary to, directly or indirectly, conduct any business, sell, lease,
transfer or otherwise dispose of any of its properties or assets to, or
purchase any property or assets from, or enter into any contract, agreement,
loan, advance or Guarantee or engage in any other transaction (or series of
related transactions which are similar or part of a common plan) with or for
the benefit of any of their respective Affiliates or any beneficial owner of
10% or more of the Common Stock of the Issuer or any officer or director of
the Issuer or any Subsidiary (each, an "Affiliate Transaction"), unless the
terms of the Affiliate Transaction are set forth in writing and are no less
favorable to the Issuer or such Restricted Subsidiary, as the case may be,
than would be available in a comparable transaction with an unaffiliated third
party. Each Affiliate Transaction (or series of related Affiliate
Transactions) involving aggregate payments and/or other consideration having
Fair Market Value (i) in excess of $1 million shall be approved by a majority
of the Board, such approval to be evidenced by a Board Resolution stating that
the Board has determined that such transaction or transactions comply with the
foregoing provisions, (ii) in excess of $5.0 million shall further require the
approval of a majority of the Disinterested Directors and (iii) in excess of
$10.0 million shall require that the Issuer obtain a written opinion from an
Independent Financial Advisor stating that the terms of such Affiliate
Transaction (or series of related Affiliate Transactions) to the Issuer or the
Restricted Subsidiary, as the case may be, are fair from a financial point of
view; provided, however, that the dollar thresholds set forth in clauses (i),
(ii) and (iii) above shall be increased to $2.5 million, $10.0 million and
$25.0 million, respectively, in the case of any Affiliate Transaction with
WorldCom or any of its Affiliates. For purposes of this covenant, any
Affiliate Transaction approved by a majority of the Disinterested Directors or
as to which a written opinion has been obtained from an Independent Financial
Advisor, on the basis set forth in the preceding sentence, shall be deemed to
be on terms that are no less favorable to the Issuer or such Restricted
Subsidiary, as the case may be, than would be available in a comparable
transaction with an unaffiliated third party and, therefore, shall be
permitted under this covenant.
 
  Notwithstanding the foregoing, the restrictions set forth in this covenant
shall not apply to (i) transactions with or among, or solely for the benefit
of, the Issuer and/or any of the Restricted Subsidiaries, provided that in any
such case, no officer, director or beneficial owner of 10% or more of any
class of Capital Stock of the Issuer
 
                                      86
<PAGE>
 
shall beneficially own any Capital Stock of any such Restricted Subsidiary,
(ii) transactions pursuant to agreements and arrangements existing on the
Issue Date and specified on a schedule to the Indenture, (iii) any Restricted
Payment made in compliance with the covenant "--Limitation on Restricted
Payments," (iv) customary directors' fees, indemnification and similar
arrangements, consulting fees, legal fees, employee salaries, bonuses and
employment agreements, compensation or employee benefit arrangements and
incentive arrangements with any officer, director or employee of the Issuer or
any Restricted Subsidiary entered into in the ordinary course of business and
payments under indemnification arrangements permitted by applicable law, (v)
loans and advances to officers, directors and employees of the Issuer or any
Restricted Subsidiary for travel, entertainment, moving and other relocation
expenses, in each case made in the ordinary course of business and consistent
with past business practices; (vi) any agreement or arrangement entered into
in the ordinary course of business by the Issuer or any Restricted Subsidiary
with WorldCom or any of its Affiliates with respect to communications or
communications related products and services; and (vii) any Permitted
Investment.
 
  Reports. The Indenture provides that, whether or not the Issuer is subject
to Section 13(a) or 15(d) of the Exchange Act or any successor provision of
law, the Issuer shall furnish without cost to each holder of Notes and file
with the Trustee (i) within 135 days after the end of each fiscal year of the
Issuer (commencing with its 1998 fiscal-year end), all annual financial
information that would be required to be contained in a filing with the SEC on
Form 10-K (whether or not the Issuer is then required to file such Form with
the SEC), including a "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and a report thereon by the Issuer's
certified public accountants, (ii) within 60 days after the end of each of the
first three fiscal quarters of each fiscal year of the Issuer, all quarterly
financial information that would be required to be contained in a filing with
the SEC on Form 10-Q (whether or not the Issuer is then required to file such
Form with the SEC), including a "Management's Discussion and Analysis of
Financial Condition and Results of Operations," and (iii) on a timely basis,
any information concerning the Issuer or any Restricted Subsidiary required to
be contained in a current report on Form 8-K (whether or not the Issuer is
then required to file such Form with the SEC). Until such time as the Issuer
is otherwise required to file periodic reports with the SEC under the Exchange
Act (or any successor provision of law), the Issuer will file with the SEC (if
permitted by SEC practice and applicable law and regulations), for public
availability, a copy of the annual and quarterly financial information and
other information prepared by it for distribution to holders of Notes. In
addition, for so long as any Notes remain outstanding the Issuer will furnish
to securities analysts and prospective investors, upon their request, the
information required to be delivered pursuant to Rule 144A(d)(4) under the
Securities Act, and, to any beneficial holder of Notes, if not obtainable from
the SEC, information of the type that wold be filed with the SEC pursuant to
the foregoing provisions, upon the request of any such holder.
 
  Limitation on Designations of Unrestricted Subsidiaries. The Indenture
provides that the Issuer will not designate any Subsidiary of the Issuer
(other than a newly created Subsidiary in which the Issuer has made an
Investment of $1,000 or less) as an "Unrestricted Subsidiary" under the
Indenture (a "Designation") unless:
 
    (a) no Default shall have occurred and be continuing at the time of or
  after giving effect to such Designation;
 
    (b) except in the case of Permitted Investments and any Investment made
  pursuant to clause (v) of the third paragraph of the covenant "--Limitation
  on Restricted Payments," at the time of and after giving effect to such
  Designation, the Issuer would be able to incur $1.00 of Indebtedness (other
  than Permitted Indebtedness) under the covenant described under "--
  Limitation on Additional Indebtedness" above; and
 
    (c) the Issuer would be permitted under the Indenture to make an
  Investment at the time of such Designation (assuming the effectiveness of
  such Designation) in an amount (the "Designation Amount") equal to the Fair
  Market Value of the interest of the Issuer and its Restricted Subsidiaries
  in such Restricted Subsidiary on such date.
 
  In the event of any such Designation, the Issuer shall be deemed to have
made an Investment constituting a Restricted Payment pursuant to the covenant
"--Limitation on Restricted Payments" for all purposes of the Indenture in an
amount equal to the Designation Amount. The Indenture will further provide
that neither the
 
                                      87
<PAGE>
 
Issuer nor any Restricted Subsidiary shall at any time (x) provide credit
support for, subject any of its properties or assets (other than the Capital
Stock of any Unrestricted Subsidiary) to the satisfaction of, or Guarantee,
any Indebtedness of any Unrestricted Subsidiary (including any undertaking,
agreement or instrument evidencing such Indebtedness), (y) be directly or
indirectly liable for any Indebtedness of any Unrestricted Subsidiary or (z)
be directly or indirectly liable for any other Indebtedness which provides
that the holder thereof may (upon notice, lapse of time or both) declare a
default thereon (or cause the payment thereof to be accelerated or payable
prior to its final scheduled maturity) upon the occurrence of a default with
respect to any other Indebtedness that is Indebtedness of an Unrestricted
Subsidiary (including any corresponding right to take enforcement action
against such Unrestricted Subsidiary), except in the case of clause (x) or (y)
to the extent otherwise permitted under the Indenture, including, without
limitation, under the covenant "--Limitation on Restricted Payments" above.
 
  The Indenture further provides that the Issuer will not revoke any
Designation of a Subsidiary as an Unrestricted Subsidiary (a "Revocation")
unless:
 
    (a) no Default shall have occurred and be continuing at the time of and
  after giving effect to such Revocation; and
 
    (b) all Liens and Indebtedness of such Unrestricted Subsidiary
  outstanding immediately following such Revocation would, if incurred at
  such time, have been permitted to be incurred for all purposes of the
  Indenture.
 
  All Designations and Revocations must be evidenced by Board Resolutions
delivered to the Trustee certifying compliance with the foregoing provisions.
 
  The Issuer designated 4-Sight and each of its Subsidiaries as a Restricted
Subsidiary at such time as 4-Sight and its Subsidiaries became Subsidiaries of
the Issuer.
 
  Limitation on Status as Investment Company. The Indenture provides that the
Issuer will not, and will not permit any of its Subsidiaries or Affiliates to,
conduct its business in a fashion that would cause the Issuer to be required
to register as an "investment company" (as that term is defined in the
Investment Company Act of 1940, as amended (the "Investment Company Act")), or
otherwise become subject to regulation under the Investment Company Act. For
purposes of establishing the Issuer's compliance with this provision, any
exemption which is or would become available under Section 3(c)(1) or Section
3(c)(7) of the Investment Company Act will be disregarded.
 
CONSOLIDATION, MERGER, SALE OF ASSETS, ETC.
 
  The Indenture provides that the Issuer will not (i) consolidate or combine
with or merge with or into or, directly or indirectly, sell, assign, convey,
lease, transfer or otherwise dispose of all or substantially all of its
properties and assets to any person or persons in a single transaction or
through a series of transactions, or (ii) permit any of the Restricted
Subsidiaries to enter into any such transaction or series of transactions if
it would result in the disposition of all or substantially all of the
properties or assets of the Issuer and the Restricted Subsidiaries on a
consolidated basis, unless, in the case of either (i) or (ii), (a) the Issuer
shall be the continuing person or, if the Issuer is not the continuing person,
the resulting, surviving or transferee person (the "surviving entity") shall
be a company organized and existing under the laws of the United States or any
State or territory thereof; (b) the surviving entity (if other than the
Issuer) shall expressly assume all of the obligations of the Issuer under the
Notes and the Indenture, and shall execute a supplemental indenture to effect
such assumption which supplemental indenture shall be delivered to the Trustee
and shall be in form and substance reasonably satisfactory to the Trustee; (c)
immediately after giving effect to such transaction or series of transactions
on a pro forma basis (including, without limitation, any Indebtedness incurred
or anticipated to be incurred in connection with or in respect of such
transaction or series of transactions), the Issuer or the surviving entity
(assuming such surviving entity's assumption of the Issuer's obligations under
the Notes and the Indenture), as the case may be, would be able to incur $1.00
of Indebtedness (other than Permitted Indebtedness) under the
 
                                      88
<PAGE>
 
covenant described under "--Certain Covenants--Limitation on Additional
Indebtedness" above; (d) immediately after giving effect to such transaction
or series of transactions on a pro forma basis (including, without limitation,
any Indebtedness incurred or anticipated to be incurred in connection with or
in respect of such transaction or series of transactions), no Default shall
have occurred and be continuing; and (e) the Issuer or the surviving entity,
as the case may be, shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel stating that such transaction or series
of transactions, and, if a supplemental indenture is required in connection
with such transaction or series of transactions, such supplemental indenture
complies with this covenant and that all conditions precedent in the Indenture
relating to the transaction or series of transactions have been satisfied.
 
  Upon any consolidation or merger or any sale, assignment, conveyance, lease,
transfer or other disposition of all or substantially all of the assets of the
Issuer in accordance with the foregoing in which the Issuer or the Restricted
Subsidiary, as the case may be, is not the surviving corporation, the
successor corporation formed by such a consolidation or into which the Issuer
or such Restricted Subsidiary is merged or to which such transfer is made,
will succeed to, and be substituted for, and may exercise every right and
power of, the Issuer or such Restricted Subsidiary, as the case may be, under
the Indenture with the same effect as if such successor corporation had been
named as the Issuer or such Restricted Subsidiary therein; and thereafter,
except in the case of (i) any lease or (ii) any sale, assignment, conveyance,
transfer, lease or other disposition to a Restricted Subsidiary of the Issuer,
the Issuer shall be discharged from all obligations and covenants under the
Indenture and the Notes.
 
  The Indenture provides that for all purposes of the Indenture and the Notes
(including the provisions of this covenant and the covenants described under
"--Certain Covenants--Limitation on Additional Indebtedness," "--Limitation on
Restricted Payments" and "--Limitation on Liens Securing Certain
Indebtedness"), Subsidiaries of any surviving entity will, upon such
transaction or series of related transactions, become Restricted Subsidiaries
or Unrestricted Subsidiaries as provided pursuant to the covenant "--Certain
Covenants--Limitation on Designations of Unrestricted Subsidiaries" and all
Indebtedness, and all Liens on property or assets, of the Issuer and the
Restricted Subsidiaries in existence immediately prior to such transaction or
series of related transactions will be deemed to have been incurred upon such
transaction or series of related transactions.
 
  The meaning of the phrase "all or substantially all" as used above varies
according to the facts and circumstances of the subject transaction, has no
clearly established meaning under relevant law and is subject to judicial
interpretation. Accordingly, in certain circumstances, there may be a degree
of uncertainty in ascertaining whether a particular transaction would involve
a disposition of "all or substantially all" of the assets of the Issuer, and
therefore it may be unclear whether the foregoing provisions are applicable.
 
EVENTS OF DEFAULT
 
  The following are "Events of Default" under the Indenture:
 
    (i) default in the payment of interest on the Notes when it becomes due
  and payable and continuance of such default for a period of 30 days or
  more; or
 
    (ii) default in the payment of the principal of, or premium, if any, on
  the Notes when due at maturity, upon redemption or otherwise; or
 
    (iii) default in the payment of the Accreted Value of, and any accrued
  and unpaid interest on, any Notes required to be purchased pursuant to a
  Change of Control Offer or Asset Sale Offer when due and payable; or
 
    (iv) default in the performance, or breach, of any covenant described
  under "--Certain Covenants--Change of Control," "--Disposition of Proceeds
  of Asset Sales" or "--Consolidation, Merger, Sale of Assets, Etc."; or
 
    (v) default in the performance, or breach, of any covenant in the
  Indenture (other than defaults specified in clause (i), (ii), (iii) or (iv)
  above), and continuance of such default or breach for a period of 30
 
                                      89
<PAGE>
 
  days or more after written notice to the Issuer by the Trustee or to the
  Issuer and the Trustee by the holders of at least 25% in aggregate
  principal amount at maturity of the outstanding Notes; or
 
    (vi) (a) failure to pay, following any applicable grace period, any
  installment of principal due (whether at maturity or otherwise) under one
  or more classes or issues of Indebtedness in an aggregate principal amount
  of $5 million or more under which the Issuer or any Material Restricted
  Subsidiary is obligated or (b) failure by the Issuer or any Material
  Restricted Subsidiary to perform any other term, covenant, condition or
  provision of one or more classes or issues of Indebtedness in an aggregate
  principal amount of $5 million or more under which the Issuer or such
  Material Restricted Subsidiary is obligated and, in the case of this clause
  (b), such failure results in an acceleration of the maturity thereof; or
 
    (vii) any holder of Indebtedness in an aggregate principal amount of $5.0
  million or more of the Issuer or any Material Restricted Subsidiary shall
  commence judicial proceedings or take any other action to foreclose upon,
  or dispose of assets of the Issuer or any Material Restricted Subsidiary
  having an aggregate Fair Market Value, individually or in the aggregate, of
  $5.0 million or more or shall have exercised any right under applicable law
  or applicable security documents to take ownership of any such assets in
  lieu of foreclosure; provided that, in any such case, the Issuer or any
  Material Restricted Subsidiary shall not have obtained, prior to any such
  foreclosure or disposition of assets, a stay of all such actions that
  remains in effect; or
 
    (viii) one or more judgments, orders or decrees for the payment of money
  of $5.0 million or more, either individually or in the aggregate, shall be
  entered against the Issuer or any Material Restricted Subsidiary or any of
  their respective properties and shall not be paid or discharged and there
  shall have been a period of 60 consecutive days or more during which a stay
  of enforcement of such judgment or order, by reason of pending appeal or
  otherwise, shall not be in effect; or
 
    (ix) certain events of bankruptcy, insolvency, reorganization,
  administration or similar proceedings with respect to the Issuer or any
  Subsidiary Guarantor shall have occurred; or
 
    (x) the Indenture or the Registration Rights Agreement ceases to be in
  full force and effect or is declared null and void or the Issuer denies
  that it has any further obligation or liability thereunder or gives notice
  to that effect (other than by reason of termination or release in
  accordance with the terms thereof); or
 
    (xi) any Subsidiary Guarantee or any provision thereof shall at any time
  cease to be the legal, valid and binding obligation of the Subsidiary
  Guarantor party thereto, such that the Holders of Notes could not
  reasonably be expected to realize the material benefits intended to be
  provided by such Subsidiary Guarantor under its Subsidiary Guarantee or any
  Subsidiary Guarantor shall assert that its Subsidiary Guarantee is not a
  legal, valid and binding obligation or shall purport to revoke its
  obligations thereunder.
 
  If an Event of Default (other than an Event of Default specified in clause
(ix) above with respect to the Issuer or any Subsidiary Guarantor) occurs and
is continuing, then the Trustee or the holders of at least 25% in principal
amount at maturity of the outstanding Notes may, by written notice, and the
Trustee upon the request of the holders of not less than 25% in principal
amount at maturity of the outstanding Notes shall, declare the Default Amount
of all outstanding Notes to be immediately due and payable and upon any such
declaration such amount shall become immediately due and payable. If an Event
of Default specified in clause (ix) above with respect to the Issuer or any
Subsidiary Guarantor occurs and is continuing, then the Default Amount of all
outstanding Notes shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any holder.
 
  After a declaration of acceleration, the holders of a majority in aggregate
principal amount at maturity of outstanding Notes may, by notice to the
Trustee, rescind such declaration of acceleration if all existing Events of
Default, other than nonpayment of the Default Amount of the Notes that has
become due solely as a result of such acceleration, have been cured or waived
and if the rescission of acceleration would not conflict with any judgment or
decree. The holders of a majority in principal amount at maturity of the
outstanding Notes also have the right to waive past defaults under the
Indenture, except a default in the payment of principal of, or any
 
                                      90
<PAGE>
 
interest on, any outstanding Note, or in respect of certain covenants or
provisions that cannot be modified or amended without the consent of all
holders of Notes.
 
  No holder of any of the Notes has any right to institute any proceeding with
respect to the Indenture or any remedy thereunder, unless the holders of at
least 25% in principal amount at maturity of the outstanding Notes have made
written request, and offered reasonable security or indemnity, to the Trustee
to institute such proceeding as Trustee, the Trustee has failed to institute
such proceeding within 60 days after receipt of such notice and the Trustee
has not within such 60-day period received directions inconsistent with such
written request by holders of a majority in principal amount at maturity of
the outstanding Notes. Such limitations do not apply, however, to a suit
instituted by a holder of a Note for the enforcement of the payment of the
principal of, or any accrued and unpaid interest on, such Note on or after the
respective due dates expressed in such Note.
 
  During the existence of an Event of Default, the Trustee is required to
exercise such rights and powers vested in it under the Indenture and use the
same degree of care and skill in its exercise thereof as a prudent person
would exercise under the circumstances in the conduct of such person's own
affairs. Subject to the provisions of the Indenture relating to the duties of
the Trustee, if an Event of Default shall occur and be continuing, the Trustee
is not under any obligation to exercise any of its rights or powers under the
Indenture at the request or direction of any of the holders unless such
holders shall have offered to such Trustee reasonable security or indemnity.
Subject to certain provisions concerning the rights of the Trustee, the
holders of a majority in principal amount at maturity of the outstanding Notes
have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee.
 
  The Indenture provides that the Trustee will, within 45 days after the
occurrence of any Default, give to the holders of the Notes notice of such
Default known to it, unless such Default shall have been cured or waived;
provided that the Trustee shall be protected in withholding such notice if it
determines in good faith that the withholding of such notice is in the
interest of such holders.
 
  The Issuer is required to furnish to the Trustee annually a statement as to
its compliance with all conditions and covenants under the Indenture.
 
DEFEASANCE
 
  The Issuer may at any time terminate all of the obligations of the Issuer
and any Subsidiary Guarantor with respect to the Notes ("defeasance"), except
for certain obligations, including those regarding any trust established for a
defeasance and obligations to register the transfer or exchange of the Notes,
to replace mutilated, destroyed, lost or stolen Notes as required by the
Indenture and to maintain agencies in respect of Notes. The Issuer may at any
time terminate the obligations of the Issuer and any Subsidiary Guarantor
under certain covenants set forth in the Indenture, some of which are
described under "--Certain Covenants" above, and any omission to comply with
such obligations shall not constitute a Default or an Event of Default with
respect to the Notes ("covenant defeasance"). To exercise either defeasance or
covenant defeasance, the Issuer must irrevocably deposit in trust, for the
benefit of the holders of the Notes, with the Trustee money (in United States
dollars) or U.S. government obligations (denominated in United States
dollars), or a combination thereof, in such amounts as will be sufficient to
pay the Accreted Value of and premium, if any, and accrued but unpaid interest
on the Notes to redemption or maturity and comply with certain other
conditions, including the delivery of a legal opinion as to certain tax
matters. The requirements for defeasance shall not be deemed satisfied if a
Default specified in clause (ix) of "--Events of Default" above occurs on or
prior to the 91st calendar day after the date of the deposit of money or
securities in the defeasance trust.
 
SATISFACTION AND DISCHARGE
 
  The Indenture will be discharged and will cease to be of further effect
(except as to surviving rights or registration of transfer or exchange of
Notes) as to all outstanding Notes when either (a) all such Notes
 
                                      91
<PAGE>
 
theretofore authenticated and delivered (except lost, stolen or destroyed
Notes that have been replaced or paid and Notes for whose payment money has
theretofore been deposited in trust or segregated and held in trust by the
Issuer and thereafter repaid to the Issuer or discharged from such trust) have
been delivered to the Trustee for cancellation; or (b) (i) all such Notes not
theretofore delivered to the Trustee for cancellation have become due and
payable and the Issuer has irrevocably deposited or caused to be deposited
with the Trustee as trust funds in trust for the purpose an amount of money
sufficient to pay and discharge the entire indebtedness on the Notes not
theretofore delivered to the Trustee for cancellation, for principal amount,
premium, if any, and accrued and unpaid interest to the date of such deposit;
(ii) the Issuer has paid all sums payable by it under the Indenture; and (iii)
the Issuer has delivered irrevocable instructions to the Trustee to apply the
deposited money toward the payment of the Notes at maturity or on the
redemption date, as the case may be. In addition, the Issuer must deliver an
Officers' Certificate and an Opinion of Counsel stating that all conditions
precedent to satisfaction and discharge have been complied with.
 
AMENDMENT AND WAIVERS
 
  From time to time, the Issuer and any Subsidiary Guarantors, when authorized
by resolutions of their respective Boards of Directors, and the Trustee,
without the consent of the holders of the Notes, may amend, waive or
supplement the Indenture or the Notes for certain specified purposes,
including, among other things, curing ambiguities, defects or inconsistencies,
maintaining the qualification of the Indenture under the Trust Indenture Act
or making any change that does not adversely affect the rights of any holder.
Other amendments and modifications of the Indenture and the Notes may be made
by the Issuer, the Subsidiary Guarantors and the Trustee by supplemental
indenture with the consent of the holders of not less than a majority of the
aggregate principal amount at maturity of the outstanding Notes; provided that
no such modification or amendment may, without the consent of the holder of
each outstanding Note affected thereby, (i) reduce the principal amount at
maturity of, change the fixed maturity of, or alter the redemption provisions
of, the Notes or amend or modify the calculation of the Accreted Value or the
Default Amount so as to reduce the amount of the Accreted Value or the Default
Amount, (ii) change the currency in which any Notes or amounts owing thereon
is payable, (iii) reduce the percentage of the aggregate principal amount at
maturity of the outstanding Notes which must consent to an amendment,
supplement or waiver or consent to take any action under the Indenture or the
Notes, (iv) impair the right to institute suit for the enforcement of any
payment on or with respect to the Notes or any Subsidiary Guarantee, (v) waive
a default in payment with respect to the Notes or any Subsidiary Guarantee,
except a rescission of acceleration of the relevant Notes by the holders
thereof as provided in the Indenture and a waiver of the payment default that
resulted from such acceleration, (vi) reduce the rate or change the time for
payment of interest on the Notes, (vii) alter the Issuer's obligation to
purchase the Notes following the occurrence of a Change of Control or an Asset
Sale in accordance with the Indenture or waive any default in the performance
thereof, (viii) affect the ranking of the Notes in a manner adverse to the
holder of the Notes or (ix) release any Subsidiary Guarantor from any of its
obligations under its Subsidiary Guarantee or the Indenture except in
compliance with the terms of the Indenture.
 
  Holders of a majority in aggregate principal amount at maturity of the
outstanding Notes, on behalf of all holders of Notes, may waive compliance by
the Issuer with certain restrictive provisions of the Indenture. Subject to
certain rights of the Trustee as provided in the Indenture, the holders of a
majority in aggregate principal amount at maturity of the Notes, on behalf of
all holders, may waive any past Default under the Indenture (including any
such waiver obtained in connection with a tender offer or exchange offer for
such Notes), except a default in the payment of principal or interest or a
Default arising from failure to purchase any Notes tendered pursuant to an
offer to purchase required to be made by any provision of the Indenture, or a
Default in respect of a provision that under the Indenture cannot be modified
or amended without the consent of the holder of each Note that is affected.
 
REGARDING THE TRUSTEE
 
  U.S. Bank Trust National Association (f/k/a First Trust National
Association) serves as Trustee under the Indenture.

be governed by and construed in accordance with the laws of the State of New
York, without giving effect to principles of conflicts of law.

any sinking fund requirements) of such Indebtedness multiplied by (b) the
amount of each such principal payment by (ii) the sum of all such principal
payments; provided that, in the case of any Capitalized Lease Obligation, all
calculations hereunder shall give effect to any applicable options to renew in
favor of the Issuer or any Restricted Subsidiary.

country); (ii) deposits, certificates of deposit or acceptances with a

                           NOTE REGISTRATION RIGHTS
 
  The Company entered into the Registration Rights Agreement with the Initial
Purchasers pursuant to which the Company agreed to file with the Commission
the Exchange Offer Registration Statement on an appropriate form under the
Securities Act with respect to an offer to exchange the Original Notes for the
Exchange Notes. Upon the effectiveness of the Exchange Offer Registration
Statement, the Company will offer to the holders of Original Notes who are
able to make certain representations the opportunity to exchange their
Original Notes for Exchange Notes. If (i) the Company is not permitted to file
the Exchange Offer Registration Statement or to consummate the Exchange Offer
because the Exchange Offer is not permitted by applicable law or Commission
policy, (ii) the Exchange Offer is not for any other reason consummated within
180 days after the Issue Date, (iii) any holder of Original Notes notifies the
Company within a specified time period that (a) due to a change in law or
policy it is not entitled to participate in the Exchange Offer, (b) due to a
change in law or policy it may not resell the Exchange Notes acquired by it in
the Exchange Offer to the public without delivering a prospectus and (x) the
prospectus contained in the Exchange Offer Registration Statement is not
appropriate or available for such resales by such holder and (y) such
prospectus is not promptly amended or modified in order to be suitable for use
in connection with such resales for such holder and all similarly situated
holders or (c) it is a broker-dealer and owns Original Notes acquired directly
from the Company or an affiliate of the Company or (iv) the holders of a
majority of the Original Notes may not resell the Exchange Notes acquired by
them in the Exchange Offer to the public without restriction under the
Securities Act and without restriction under applicable blue sky or state
securities laws, the Company will file with the Commission the Shelf
Registration Statement to cover resales of the Transfer Restricted Notes (as
defined below) by the holders thereof. The Company agreed it will use its best
efforts to cause the applicable registration statement to be declared
effective as promptly as possible by the Commission. For purposes of the
foregoing, "Transfer Restricted Notes" means each Original Note until (i) the
date on which such Original Note has been exchanged by a person other than a
broker-dealer for an Exchange Note in the Exchange Offer, (ii) following the
exchange by a broker-dealer in the Exchange Offer of an Original Note for an
Exchange Note, the date on which such Exchange Note is sold to a purchaser who
receives from such broker-dealer on or prior to the date of such sale a copy
of the prospectus contained in the Exchange Offer Registration Statement,
(iii) the date on which such Original Note has been effectively registered
under the Securities Act and disposed of in accordance with the Shelf
Registration Statement, (iv) the date on which such Original Note is
distributed to the public pursuant to Rule 144(k) under the Securities Act (or
any similar provision then in force, but not Rule 144A under the Securities
Act), (v) such Original Note shall have been otherwise transferred by the
holder thereof and a new Note not bearing a legend restricting further
transfer shall have been delivered by the Company and subsequent disposition
of such Note shall not require registration or qualification under the
Securities Act or any similar state law then in force or (vi) such Note ceases
to be outstanding.
 
  Under existing Commission interpretations, the Exchange Notes would, in
general, be freely transferable after the Exchange Offer without further
registration under the Securities Act; provided that in the case of broker-
dealers participating in the Exchange Offer, a prospectus meeting the
requirements of the Securities Act must be delivered upon resale by such
broker-dealers in connection with resales of the Exchange Notes. The Company
has agreed, for period of 180 days after consummation of the Exchange Offer,
to make available a prospectus meeting the requirements of the Securities Act
to any such broker-dealer for use in connection with any resale of any
Exchange Notes acquired in the Exchange Offer. A broker-dealer which 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 provisions of the Registration Rights Agreement
(including certain indemnification rights and obligations).
 
  Each holder of Original Notes that wishes to exchange such Original Notes
for Exchange Notes in the Exchange Offer will be required to make certain
representations, including representations that (i) any Exchange Notes to be
received by it will be acquired in the ordinary course of its business, (ii)
it has no arrangement with any person to participate in the distribution of
the Exchange Notes and (iii) it is not an "affiliate," as defined in Rule 405
of 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.

  The Registration Rights Agreement provides that: (i) unless the Exchange

Exchange Offer would not be permitted by applicable law or Commission policy,
the Company will use its best efforts to have the Exchange Offer Registration
Statement declared effective by the Commission on or prior to the 150th day
after the Issue Date (the "Target Effectiveness Date"), (iii) unless the
Exchange Offer would not be permitted by applicable law or Commission policy,
the Company will commence the Exchange Offer and use its best efforts to
issue, on or prior to the date which is 30 days after the date on which the
Exchange Offer Registration Statement was declared effective by the
Commission, Exchange Notes in Exchange for all Original Notes tendered prior
thereto in the Exchange Offer and (iv) if obligated to file the Shelf
Registration Statement, the Issuer will use its best efforts to file prior to
the later of (a) the 90th day after the Issue Date or (b) the 30th day after
such filing obligation arises and will use its best efforts to cause the Shelf
Registration Statement to be declared effective by the Commission on or prior
to the 60th day after such obligation arises; provided that if the Issuer has
not consummated the Exchange Offer within the date which is 180 days after the
Issue Date, then the Company will file the Shelf Registration Statement with
the Commission on or prior to the 30th day after such date. The Company shall
use its best efforts to keep such Shelf Registration Statement continuously
effective, supplemented and amended until the earlier of (i) the second
anniversary of the effective date of the Shelf Registration Statement and (ii)
such time as all of the Transfer Restricted Notes covered by the Shelf
Registration Statement have been sold thereunder or otherwise cease to be
Transfer Restricted Notes.
 
  If (i) the Company fails to file any of the registration statements required
by the Registration Rights Agreement on or before the date specified for such
filing, (ii) any of such registration statements is not declared effective by
the Commission on or prior to the Target Effectiveness Date (subject to
certain limited exceptions), (iii) the Company fails to consummate the
Exchange Offer within 30 days of the Target Effectiveness Date with respect to
the Exchange Offer Registration Statement, or (iv) the Shelf Registration
Statement or the Exchange Offer Registration Statement is declared effective
but thereafter, subject to certain limited exceptions, ceases to be effective
or usable in connection with the Exchange Offer or resales of Transfer
Restricted Notes, as the case may be, during the periods specified in the
Registration Rights Agreement (each such event referred to in clauses (i)
through (iv) above, a "Registration Default"), then the Company shall pay as
liquidated damages interest on the Transfer Restricted Notes as to which any
Registration Default exists. If a Registration Default exists with respect to
Transfer Restricted Notes, the Company will, with respect to the first 90-day
period (or portion thereof) while such Registration Default is continuing
immediately following the occurrence of such Registration Default, make cash
payments at a rate of .50% per annum multiplied by the Accreted Value of the
Transfer Restricted Notes as of the date such payment is required to be made.
The rate of such cash payment shall increase by an additional .50% per annum
at the beginning of each subsequent 90-day period (or portion thereof) while
such Registration Default is continuing until such Registration Default is
cured, up to a maximum rate of 1.5% per annum. Following the cure of all
Registration Defaults, the making of cash payments with respect to the Notes
will cease and the interest rate on the Notes will revert to zero.

                         BOOK-ENTRY; DELIVERY AND FORM
 
  Except as set forth below, the Exchange Notes will be registered in book-
entry form and will be represented by a single Global Exchange Note in
definitive, fully registered form without interest coupons and will be
deposited with the Trustee as custodian for DTC and registered in the name of
Cede & Co. or such other nominee as DTC may designate. Beneficial interests in
the Global Exchange Security will be shown on, and transfers thereon will be
effected only through, records maintained by DTC and its direct and indirect
participants, and any such interest may not be exchanged for Notes in
certificated form except in the circumstances described below.
 
  DTC has advised the Issuer as follows: DTC is a limited purpose trust
company organized under the laws of the State of New York, a "banking
organization" within the meaning of the New York Banking Law, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the
Uniform Commercial Code and a "Clearing Agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC was created to hold
securities for its participants and facilitate the clearance and settlement of
securities transactions between participants through electronic book-entry
changes in accounts of its participants, thereby eliminating the need for
physical movement of certificates. Participants include securities brokers and
dealers, banks, trust companies and clearing corporations and certain other
organizations. Indirect access to the DTC system is available to others such
as banks, brokers, dealers and trust companies that clear through or maintain
a custodial relationship with a participant, either directly or indirectly
("indirect participants").
 
  Upon the issuance of the Global Exchange Note, DTC or its custodian will
credit, on its internal system, the respective principal amount of the
applicable Exchange Note represented by such Global Exchange Note to the
accounts of persons who have accounts with DTC. Ownership of beneficial
interests in the Global Securities will be limited to persons who have
accounts with DTC ("participants") or persons who hold interests through
participants. Ownership of beneficial interests in the Global Exchange Note
will be shown on, and the transfer of that ownership will be effected only
through, records maintained by DTC or its nominee (with respect to interests
of participants) and the records of participants (with respect to interests of
persons other than participants). The laws of some jurisdictions may require
that certain purchasers of securities take physical delivery of such
securities in definative form. Such limits and laws may impair the ability to
transfer or pledge beneficial interest in each such Global Exchange Note.
 
  So long as DTC or its nominee is the registered owner or holder of a Global
Exchange Note, DTC or such nominee, as the case may be, will be considered the
sole record owner or holder of the Exchange Note represented by such Global
Exchange Note for all purposes under the Indenture and the Notes. No
beneficial owner of an interest in the Global Exchange Note will be able to
transfer that interest except in accordance with DTC's applicable procedures
in addition to those provided for under the Indenture.
 
  Payments in respect of the Global Exchange Note will be made to DTC or its
nominee, as the case may be, as the registered owner thereof. None of the
Issuer, the Trustee or any paying agent will have any responsibility or
liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests in the Global Exchange Note or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.
 
  The Company expects that DTC or its nominee, upon receipt of any payment in
respect of the Global Exchange Note, will credit participants' accounts with
payments in amounts proportionate to their respective beneficial ownership
interests in such Global Exchange Note, as shown on the records of DTC or its
nominee. The Company also expects that payments by participants to owners of
beneficial interests in such Global Exchange Note held through such
participants will be governed by standing instructions and customary
practices, as is now the case with securities held for the accounts of
customers registered in the names of nominees for such customers. Such
payments will be the responsibility of such participants.
 
 
                                      109
<PAGE>
 
  Transfers between participants in DTC will be effected in the ordinary way
in accordance with DTC rules. If a holder requires physical delivery of
Certificated Notes for any reason, including selling Units, Notes or Warrants
to persons in states which require delivery of such Notes or pledging such
Notes, such holder must transfer its interest in the Global Exchange Note, in
accordance with the normal procedures of DTC and the procedures set forth in
the Indenture.
 
  DTC has advised the Company that DTC will take any action permitted to be
taken by a holder of Notes only at the direction of one or more participants
to whose account the DTC interests in the Global Exchange Notes are credited
and only in respect of such portion of the aggregate amount of Exchange Notes
as to which such participant or participants has or have given such direction.
However, if there is an Event of Default under the Indenture, DTC will
exchange the applicable Global Exchange Notes for Certificated Securities,
which it will distribute to its participants.
 
  Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in Global Exchange Notes among participants of DTC, it
is under no obligation to perform such procedures, and such procedures may be
discontinued at any time. Neither of the Issuer or the Trustee will have any
responsibility for the performance by DTC or its participants or indirect
participants of their respective obligations under the rules and procedures
governing their operations.
 
  Subject to certain conditions, any person having a beneficial interest in a
Global Exchange Note may, upon request to the Trustee, exchange such
beneficial interest for Notes in the form of Certificated Exchange Notes. Upon
any such issuance, the Trustee is required to register such Certificated
Exchange Notes in the name of, and cause the same to be delivered to, such
person or persons (or the nominee of any thereof). In addition, if DTC is at
any time unwilling or unable to continue as a depositary for the Global Notes
and a successor depositary is not appointed by the Issuer within 90 days, the
Issuer will issue Certificated Exchange Notes in exchange for the Global
Exchange Notes.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
   
  The following discussion is a summary of the material United States federal
income tax considerations relevant to the exchange of Original Notes for
Exchange Notes pursuant to the Exchange Offer and the ownership and
disposition of Exchange Notes by holders who acquire the Exchange Notes
pursuant to the Exchange Offer, but does not purport to be a complete analysis
of all potential tax effects. This discussion was prepared by Willkie Farr &
Gallagher and, as herein limited, constitutes such counsel's opinion of the
expected material U.S. federal income tax consequences of the Exchange Offer.
The discussion is based upon the Internal Revenue Code of 1986, as amended
(the "Code"), U.S. Treasury Regulations, Internal Revenue Service ("IRS")
rulings and pronouncements and judicial decisions all in effect as of the date
hereof, all of which are subject to change at any time, and any such change
may be applied retroactively in a manner that could adversely affect a holder
of the Notes. The discussion does not address all of the U.S. federal income
tax consequences that may be relevant to a holder in light of such holder's
particular circumstances or to holders subject to special rules, such as
certain financial institutions, insurance companies, dealers in securities,
tax-exempt organizations and persons holding the Notes as part of a
"straddle," "hedge" or "conversion transaction." In addition, this discussion
is limited to persons purchasing the Original Notes at the issue price.
Moreover, the effect of any applicable state, local or foreign tax laws is not
discussed. The discussion deals only with Notes held as "capital assets"
within the meaning of Section 1221 of the Code.     
 
  As used herein, "U.S. holder" means a beneficial owner of the Exchange Notes
who or that (i) is a citizen or resident of the United States, (ii) is a
corporation, partnership or other entity created or organized in or under the
laws of the United States or political subdivision thereof, (iii) is an estate
the income of which is subject to U.S. federal income taxation regardless of
its source, (iv) is a trust if (A) a U.S. court is able to exercise primary
supervision over the administration of the trust and (B) one or more U.S.
persons have authority to control all substantial decisions of the trust, or
(v) is otherwise subject to U.S. federal income tax on a net income basis in
respect of the Notes. As used herein, a "non-U.S. holder" means a holder who
or that is not a U.S. holder.
 
  The Company has not sought and will not seek any rulings from the IRS with
respect to the position of the Company discussed below. There can be no
assurance that the IRS will not take a different position concerning the tax
consequences of the exchange of Original Notes for Exchange Notes and the
ownership or disposition of the Exchange Notes by holders who acquire the
Exchange Notes pursuant to the Exchange Offer or that any such position would
not be sustained.
 
  PROSPECTIVE HOLDERS OF EXCHANGE NOTES SHOULD CONSULT THEIR OWN TAX ADVISORS
WITH REGARD TO THE APPLICATION OF THE TAX CONSIDERATIONS DISCUSSED BELOW TO
THEIR PARTICULAR SITUATIONS AS WELL AS THE APPLICATION OF ANY STATE, LOCAL,
FOREIGN OR OTHER TAX LAWS, INCLUDING GIFT AND ESTATE TAX LAWS.
 
THE EXCHANGE OFFER
   
  The Exchange of Original Notes for Exchange Notes pursuant to the Exchange
Offer will not be treated as an exchange or other taxable event for United
States federal income tax purposes because, under the Regulations, the
Exchange Notes do not differ materially in kind or extent from the Original
Notes. Rather, the Exchange Notes received by a holder will be treated as a
continuation of the Original Notes in the hands of such holder. As a result,
there will be no United States federal income tax consequences to holders who
exchange Original Notes for Exchange Notes pursuant to the Exchange Offer and
any such holder will have the same tax basis and holding period in the
Exchange Notes as it had in the Original Notes immediately before the
exchange.     
 
U.S. HOLDERS
 
The Units
 
  The purchase of a Unit consisting of a Note and Warrants will be treated as
the purchase of an "investment unit" for federal income tax purposes. The
"issue price" of the Units will be the first price at which a substantial
 
                                      111
<PAGE>
 
amount of the Units is sold to the public (excluding sales to bond houses,
brokers, or similar persons or organizations acting in the capacity of
underwriters or wholesalers). The aggregate issue price of the Unit must be
allocated among the Note and the Warrants based on their relative fair market
values on the date of issuance of the Unit to determine the issue price of
each of the securities. The Company believes that the aggregate issue price of
each Unit should be allocated $114,944,000 to the Notes and $10,057,000 to the
Warrants, which amounts are based on the instruments' anticipated relative
fair market value at the time of issuance. Although the Company's allocation
is not binding on the IRS, a U.S. holder of a Unit must use the Company's
allocation unless the U.S. holder discloses on its federal income tax return
for the year in which the Unit was acquired that it plans to use an allocation
that is inconsistent with the Company's allocation. A U.S. holder's initial
tax basis in each security will be the issue price allocated thereto.
 
The Notes
 
  Original Issue Discount. Because the Notes were issued at a discount from
their "stated redemption price at maturity," the Notes have original issue
discount ("OID") for federal income tax purposes. A U.S. holder will be
required to include OID in income periodically over the term of a Note before
receipt of the cash or other payment attributable to such income, regardless
of the U.S. holder's method of tax accounting. For federal income tax
purposes, OID on a Note will be the excess of the "stated redemption price at
maturity" of the Note over its "issue price."
 
  The "stated redemption price at maturity" of a Note is the sum of all
payments required to be made on such Note, whether denominated as principal or
interest, other than payments of "qualified stated interest." "Qualified
stated interest" is stated interest that is unconditionally payable at least
annually at a single fixed rate that appropriately takes into account the
length of the interval between payments. Prior to March 1, 2002 there will be
no payment of interest on the Notes. Therefore, none of the interest payments
on the Notes will constitute qualified stated interest and all such payments
will be included in the Notes, stated redemption price at maturity. Therefore,
each Note will bear OID in an amount equal to the excess of (i) the sum of its
principal amount and all stated interest payments over (ii) the issue price.
 
  The amount of OID required to be included in a U.S. holder's gross income
for any taxable year is the sum of the "daily portions" of OID with respect to
the Note for each day during the taxable year or portion of a taxable year
during which such U.S. holder holds the Note. The daily portion is determined
by allocating to each day of any "accrual period" within a taxable year a pro
rata portion of an amount equal to the "adjusted issue price" of the Note at
the beginning of the accrual period multiplied by the "yield to maturity" of
the Note. Accrual periods with respect to a Note may be of any length selected
by the holder and may vary in length over the term of the Note as long as (i)
no accrual period is longer than one year and (ii) each scheduled payment of
interest or principal on the Note occurs on either the first or final day of
an accrual period. The "adjusted issue price" of a Note at the beginning of
any accrual period is the original issue price of the Note increased by the
amount of OID previously includible in the gross income of the U.S. holder,
and decreased by any payments (including interest that is not qualified stated
interest) previously made on the Note. The "yield to maturity" is the interest
rate, expressed as a constant annual interest rate, that when used in
computing the present value of all payments of principal and interest to be
paid in connection with a Note produces an amount equal to the issue price of
the Note.
 
  Because the yield to maturity with respect to the Notes will exceed the sum
of the "applicable federal rate" plus five percentage points, the Notes will
be treated as applicable high yield discount obligations ("AHYDOs") under the
Code. Accordingly, no deduction will be allowed to the Company for the
"disqualified portion" of the OID, and the remainder of the OID will be
deductible only when paid. The "disqualified portion" of the OID will
generally be the OID relating to that portion of the Notes' yield to maturity
that exceeds the "applicable federal rate" plus six percentage points.
Additionally, the "disqualified portion" of the OID may be treated as a
dividend for purposes of the "dividend received deduction" to the extent that
the OID would have been a dividend if distributed with respect to the
Company's stock. Holders are advised to consult their tax advisors regarding
the applicability and operation of the AHYDO rules to their investment in the
Notes.
 
                                      112
<PAGE>
 
  Sale or Retirement of a Note. A U.S. holder of a Note will recognize gain or
loss upon the sale, retirement, redemption or other taxable disposition of
such Note in an amount equal to the difference between (a) the amount of cash
and the fair market value of other property received in exchange therefor
(other than amounts attributable to accrued but unpaid stated interest) and
(b) the U.S. holder's adjusted tax basis in such Note. Any gain or loss
recognized will generally be capital gain or loss. A non-corporate U.S. holder
is generally subject to a maximum capital gains rate of 28% for Notes held for
more than one year and a maximum capital gains rate of 20% for Notes held for
more than eighteen months.
 
  A U.S. holder's tax basis in a Note will generally be equal to the issue
price of such Note, increased by the amount of OID, if any, included in gross
income prior to the date of disposition, and decreased by the amount of any
payment on such Note other than stated interest prior to disposition.
 
  U.S. holders should be aware that the resale of the Notes may be affected by
the "market discount" rules of the Code, under which a purchaser of a Note
acquiring the Note at a market discount generally would be required to include
as ordinary income a portion of the gain realized upon the disposition or
retirement of such Note, to the extent of the market discount that has accrued
but has not been included in income while such Note was held by such
purchaser.
 
NON-U.S. HOLDERS
 
 U.S. Withholding Tax
 
  Interest or redemption proceeds paid to non-U.S. holders of the Notes will
not be subject to U.S. withholding tax, provided that (i) the non-U.S. Holder
does not actually or constructively own 10% or more of the total combined
voting power of all classes of stock of the Company, (ii) the non-U.S. Holder
is not (a) a controlled foreign corporation as to the United States that is
related to the Company through stock ownership or (b) a bank that received the
Note on an extension of credit made pursuant to a loan agreement entered into
in the ordinary course of its trade or business, and (iii) the beneficial
owner of the Note provides a statement signed under penalties of perjury that
includes its name and address and certifies that it is not a U.S. person in
compliance with applicable requirements or an exemption is otherwise
established. If these requirements cannot be met, a non-U.S. holder will be
subject to U.S. withholding tax at a rate of 30% (or lower treaty rate, if
applicable) on interest payments. Although U.S. tax will also be imposed
against OID on the Notes prior to payment, such tax will only be withheld from
stated interest payments on the Notes. However, such additional withholding
may result in U.S. withholding tax on stated interest payments exceeding 30%.
 
  Recently promulgated Treasury Regulations (the "New Regulations") regarding
U.S. withholding tax and information reporting and backup withholding
(discussed below) will apply to payments made after December 31, 1999. The New
Regulations provide alternative methods for satisfying the certification
requirements discussed in clause (iii) above and clarify and modify reliance
standards. The New Regulations also address certain issues relating to
intermediary certification procedures designed to simplify compliance by
withholding agents. Non-U.S. holders should consult their own tax advisors
regarding the effect of the New Regulations.
 
  In general, any gain realized by any non-U.S. Holder upon the sale, exchange
or redemption of a Note will not be subject to United States withholding tax.
However, such gain will be subject to U.S. withholding tax if (i) a non-U.S.
holder is an individual and is present in the United States for a total of 183
days or more during the taxable year in which the gain is realized, or (ii)
such gain is effectively connected with a U.S. trade or business.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
  Certain non-corporate U.S. persons may be subject to backup withholding at a
rate of 31% on payments of principal and interest (including payments of OID)
on the Notes and the proceeds from a disposition of the Notes. Backup
withholding will only be imposed where the holder (i) fails to furnish its
taxpayer identification number ("TIN"), which, for an individual, would
ordinarily be his or her social security number, (ii) furnishes an
 
                                      113
<PAGE>
 
incorrect TIN, (iii) is notified by the IRS that it has failed to properly
report payments of interest or dividends, or (iv) under certain circumstances,
fails to certify, under penalties of perjury, that it has furnished a correct
TIN and has not been notified by the IRS that it is subject to backup
withholding. Holders of the Notes should consult their own tax advisors
regarding their qualification for exemption from backup withholding and the
procedure for obtaining such an exemption, if applicable. However, principal
and interest (including OID) paid with respect to a Note and received by a
non-U.S. holder will not be subject to information reporting or backup
withholding if the payor has received appropriate certification statements and
provided that the payor does not have actual knowledge that the holder is a
U.S. person.

                             PLAN OF DISTRIBUTION
   
  Based on interpretations by the Staff set forth in no-action letters issued
to third parties, the Company believes that Exchange Notes issued pursuant to
the Exchange Offer in exchange for the Original Notes may be offered for
resale, resold and otherwise transferred by Holders thereof (other than any
Holder which is (i) an "affiliate" of the Company within the meaning of Rule
405 under the Securities Act, (ii) a broker-dealer who acquired Original Notes
directly from the Company or (iii) broker-dealers who acquired Original Notes
as a result of market-making or other trading activities) 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 engaged in, and do not intend to
engage in, and have no arrangement or understanding with any person to
participate in, a distribution of such Exchange Notes; provided that broker-
dealers ("Participating Broker-Dealers") receiving Exchange Notes in the
Exchange Offer will be subject to a prospectus delivery requirement with
respect to resales of such Exchange Notes. To date, the Staff has taken the
position that Participating Broker-Dealers may fulfill their prospectus
delivery requirements with respect to transactions involving an exchange of
securities such as the exchange pursuant to the Exchange Offer (other than a
resale of an unsold allotment from the sale of the Original Notes to an
Initial Purchaser) with a current Prospectus meeting the requirements of the
Securities Act. Pursuant to the Registration Rights Agreement, the Company has
agreed to permit Participating Broker-Dealers and other persons, if any,
subject to similar prospectus delivery requirements to use this Prospectus in
connection with the resale of such Exchange Notes. The Company has agreed that
they will make this Prospectus, and any amendment or supplement to this
Prospectus, available to any broker-dealer that reasonably requests such
documents in the Letter of Transmittal.     
 
  Each Holder of the Original Notes who wishes to exchange its Original Notes
for Exchange Notes in the Exchange Offer will be required to make certain
representations to the Company as set forth in "The Exchange Offer--Terms and
Conditions of the Letter of Transmittal." In addition, each Holder who is a
broker-dealer and who receives Exchange Notes for its own account in exchange
for Original Notes that were acquired by it as a result of market-making
activities or other trading activities, will be required to acknowledge that
it will deliver a prospectus in connection with any resale by it of such
Exchange Notes.
   
  The Company will not receive any proceeds from any sale of 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 at negotiated prices. Any
such resale may be made directly to purchasers 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 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 a
statutory "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.     
 
  The Company has agreed to pay all expenses incidental to the Exchange Offer
other than commissions and concessions of any brokers or dealers and will
indemnify Holders of the Notes (including any broker-dealers) against certain
liabilities, including liabilities under the Securities Act, as set forth in
the Registration Rights Agreement.

                        REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
WAM!NET Inc.
 
  We have audited the accompanying consolidated balance sheets of WAM!NET Inc.
(formerly known as NetCo Communications Corporation) as of December 31, 1996
and 1997, and the related consolidated statements of operations, shareholders'
deficit and cash flows for each of the years in the three year period ended
December 31, 1997. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  Since the date of completion of our audits of the accompanying consolidated
financial statements and the initial issuance of our report thereon dated
February 9, 1998, which report contained an explanatory paragraph regarding
the Company's ability to continue as a going concern, the Company, as
discussed in Note 2, has completed an issuance of Senior Discount Notes
resulting in net proceeds of $120,622,093. Therefore, the conditions that
raised substantial doubt about whether the Company will continue as a going
concern no longer exist.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of WAM!NET Inc. at December 31, 1996 and 1997, and the consolidated results of
its operations and its cash flows for each of the years in the three year
period ended December 31, 1997 in conformity with generally accepted
accounting principles.
 
                                                              Ernst & Young LLP

1. SIGNIFICANT ACCOUNTING POLICIES
 
 Description of Business
 
  WAM!NET Inc. (formerly known as NetCo Communications Corporation), (the
"Company") provides a managed, high speed digital data delivery network
service that integrates the Company's industry-specific work flow applications
with high speed computer and telephony technologies. The Company offers
digital data delivery service designed to provide its subscribers with the
rapid, secure, accurate and reliable transportation and management of
information. In late 1997, the Company no longer considered itself in the
development stage.
 
  The Company was incorporated in Minnesota on September 19, 1994. The Company
was inactive from September 19, 1994 (inception) through December 31, 1994.
 
 Substantial Ownership
 
  Through its ownership of debt and equity securities of the Company, as well
as its designation of a majority of the directors of the Board of Directors of
the Company, WorldCom Inc. ("WorldCom") has the potential to exercise
considerable influence and control over the affairs of the Company. In
addition, WorldCom and its affiliates are non-exclusive suppliers of
telecommunication and other services to the Company.
 
 Consolidation
   
  The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries from their respective dates of acquisition:
FreeMail, Inc., NetCo Communications of Canada, Inc. and WAM!NET U.K. Limited
(formerly 4-Sight Limited). All intercompany transactions have been
eliminated.     
 
 Revenue Recognition
   
  Revenues from user fees are recorded as revenue in the period the service is
provided to the customer. Revenue is derived primarily from contracts which
are usually annual, automatically renewable service contracts with a minimum
monthly fee and additional charges for usage exceeding the monthly minimum.
The Company begins to earn gross revenue following installation of service at
a customer's premise. The Company also incurs service rebates that offset the
gross revenue generated by the Company. Revenue from hardware and software
sales is recognized upon delivery of the hardware and software. Upon delivery
of the hardware and software, the Company has no remaining obligations to the
customer. Other service fees are recognized as revenue in the period the
service is provided to the customer.     
 
 Cash and Cash Equivalents
 
  The Company considers all highly liquid investments with a maturity of three
months or less at the time of purchase to be cash equivalents. Investments
classified as cash equivalents consist of high grade commercial paper (A1/P1),
certificates of deposits and United States Treasury Bills.
 
 Investments
 
  Investments at December 31, 1996 consist of certificates of deposits which
are classified as available for sale. The cost of investments approximates
fair value.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
  (UNAUDITED WITH RESPECT TO MARCH 31, 1998 AND THE THREE MONTH PERIOD ENDED
                                MARCH 31, 1998)
 
               (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
 
SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
 Property and Equipment
 
  Property and equipment are stated at cost. Depreciation is provided on a
straight-line basis over the estimated useful life of four to seven years.
 
 Goodwill
   
  The excess of the cost over the fair value of the net assets acquired is
amortized on a straight-line basis over three to five years. The Company
periodically reviews the recoverability of goodwill based on estimated future
cash flows from the related operations.     
 
 Impairment of Long-Lived Assets
 
  The Company will record impairment losses on long-lived assets used in
operations when indicators of impairment are present and the undiscounted cash
flows estimated to be generated by those assets are less than the assets'
carrying amount.
 
 Income Taxes
 
  Income taxes are accounted for under the liability method. Deferred income
taxes are provided for temporary differences between the financial reporting
and tax bases of assets and liabilities.
 
 Research and Development
 
  Research and development costs are charged to operations in the year
incurred. These costs for 1995, 1996 and 1997 were $539, $1,109 and $3,364,
respectively.
 
 Foreign Currency Translation and Transactions
 
  The Company's Canadian subsidiary's functional currency is considered to be
its local currency. The effect of the cumulative translation adjustment for
the fiscal year ended December 31, 1997 is not material and has not been
separately disclosed in the Company's financial statements.
   
 Concentration of Credit Risk     
   
  Financial instruments that potentially subject the Company to credit risk
consist primarily of accounts receivable. The Company grants credit to
customers in the ordinary course of business. No single customer or region
represents a significant concentration of credit risk.     
 
 Stock Split
 
  In February, 1998, the Board of Directors declared a five-for-one Common
Stock split effected in the form of a stock dividend. The number of shares,
options and warrants and the conversion price and exercise price per share
have been adjusted to reflect this stock split on a retroactive basis.
 
 Net Loss Per Common Share
 
  In 1997, the Financial Accounting Standards Board issued Statement No. 128,
Earnings per Share (Statement 128). Statement 128 replaced the calculation of
primary and fully diluted earnings per share with
 
                                     F-10

SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
basic and diluted earnings per share. Unlike primary earnings per share, basic
earnings per share excludes any dilutive effects of options, warrants and
convertible securities. Diluted earnings per share is very similar to fully
diluted earnings per share under the previous rules. All earnings per share
amounts for all periods have been presented, and where necessary, restated to
conform to the Statement 128 requirements. Diluted earnings per share is not
presented as the effect of outstanding options and warrants are antidilutive.
 
 Interim Financial Information
   
  The accompanying consolidated financial statements as of March 31, 1998 and
for the three month periods ended March 31, 1997 and 1998 are unaudited. In
the opinion of the management of the Company, these consolidated financial
statements reflect all adjustments, consisting only of normal and recurring
adjustments necessary for a fair presentation of the consolidated financial
statements. The results of operations for the three month period ended March
31, 1998 are not necessarily indicative of the results that may be expected
for the year ending December 31, 1998.     
       
 Reclassification
 
  Certain amounts presented in the December 31, 1996 financial statements have
been reclassified to conform with the December 31, 1997 presentation.
 
2. CONTINUED EXISTENCE
   
  On March 5, 1998, the Company sold 208,530 Units consisting of 13 1/4%
Senior Discount Notes due 2005 and warrants to purchase a total of 1,257,436
shares of common stock. Each Unit consists of $1 principal amount at maturity
of 13 1/4% Senior Discount Notes and three warrants. Each warrant entitles the
holder to purchase 2.01 shares of common stock at an exercise price of $.01
per share. The sale of the Units resulted in net proceeds to the Company of
$120,622. See Note 3. Prior to the sale of the Units, there was substantial
doubt about the Company's ability to continue as a going concern. With the
completion of the Unit offering, the Company believes that it has a sufficient
cash on hand to satisfy its cash requirements for at least the next twelve
months.

SENIOR DISCOUNT NOTES     
   
  On March 5, 1998, the Company sold 208,530 Units. Each Unit consists of $1
principal amount at maturity of 13 1/4% Senior Discount Notes and three
warrants. The aggregate principal amount of the Notes payable at maturity is
$208,530. The sale of the Units resulted in net proceeds to the Company of
$120,622. Cash interest does not accrue nor is it payable on the Notes prior
to March 1, 2002. Thereafter, cash interest on the Notes will accrue on the
Notes at a rate of 13 1/4% per annum (calculated on a semiannual bond
equivalent basis) and will be payable semiannually in arrears on March 1 and
September 1 of each year, commencing September 1, 2002.     
   
  In connection with the 13 1/4% Senior Discount Notes, the Company issued
625,590 warrants to purchase a total of 1,257,436 shares of common stock. Each
warrant entitles the holder to purchase 2.01 shares of common stock at an
exercise price of $.01 per share. The warrants were deemed to have a value of
$10,047, which will be amortized as interest expense over the life of the
Notes. The unamortized value of the warrants has been reflected in the
financial statements as a reduction of the Notes.     
 
LINE OF CREDIT AGREEMENT
   
  In September 1997, the Company entered into a three year $25,000 line of
credit agreement with a bank. The line of credit is guaranteed by WorldCom and
the Company must obtain WorldCom's consent prior to each borrowing under the
line. At December 31, 1997, the amount outstanding on the line of credit was
$18,800. The line of credit has both Eurodollar and Floating Rate advances.
The Eurodollar and Floating Rate accrue interest at 55 basis points above
LIBOR (6.27% at December 31, 1997) and prime (8.50% at December 31, 1997),
respectively. Interest on the LIBOR borrowings is payable upon maturity and
the prime borrowings is payable quarterly. The aggregate principal amount
outstanding under the Revolving Credit Facility as of March 31, 1998 was $0.
    
  In connection with WorldCom's guarantee of the line of credit agreement, the
Company issued Class A warrants to purchase 8,396,170 common shares and Class
B Warrants to purchase 14,204,835 common shares at an initial exercise price
of $3.90 per share. The Class A warrants are immediately exercisable and
expire on December 31, 2000. The Class A warrants were deemed to have a value
of $4,766 which will be amortized as interest expense over the life of the
agreement. Amortization of the warrants for the year ended December 31, 1997
was $397. The unamortized value of the warrants has been reflected in the
financial statements as a reduction of the outstanding amount owed under the
line of credit. The Class B warrants are exercisable based on a calculation
that factors the outstanding balance and repayments made on the line of credit
during the final twelve months of the agreement. The Class B warrants expire
on December 31, 2000. It is Management's intention to fully repay the credit
facility before the final twelve months of the agreement with funds received
in a proposed Rule 144A private placement by the end of the first quarter
1998. The Class B warrants were deemed to have no value based on Management's
intentions and the unpredictability of the factors used to calculate the
number of warrants exercisable.
 
4. BRIDGE FINANCING

(Bridge Loan) which provides funding up to $1,600. The Bridge Loan accrued

8. CAPITAL STOCK
 
  In February 1998, the Company amended the Articles of Incorporation to
increase its authorized capital from 20,000,000 shares to 100,000,000 shares,
90,000,000 of which shall be classified as common shares, 100,000 of which

9. STOCK OPTIONS AND WARRANTS
 
  In September 1994, the Company adopted an Incentive Stock Option Plan that
includes incentive stock options to be granted to certain eligible employees
and non-employee directors of the Company. The Company has authorized the
grant of options to management personnel for up to 22,071,400 shares and up to

respectively. A majority of the options granted have 10 year terms and vest
and become fully exercisable at the end of 3 years of continued employment.

STOCK OPTIONS AND WARRANTS (CONTINUED)
   
  In November 1996, the Chief Executive Officer and Chief Technology Officer
were each granted options to purchase 2,000,000 shares of common stock at an
exercise price of $.96. These options vest in incremental amounts based on the
number of installed customer sites and remain exercisable until December 31,
2007. In 1997, the Company recorded $297 in compensation relating to these
option grants. Subsequent to year end, the Board of Directors agreed to amend
the stock option agreements whereas the shares are fully vested effective
January 3, 1998. The amendment constitutes a repricing and accordingly the
Company recorded $11,405 as compensation expense in January 1998.     
 
  During 1997, the Company granted non-plan options to various consultants to
purchase 347,500 shares of the Company's common stock at an exercise price of
$.96 per share. The options were deemed to have a value of $92 and was
recognized as compensation expense.
 
  Subsequent to December 31, 1997, the Company granted to employees options to
purchase a total of 656,250 shares of common stock at an exercise price of
$3.90 per share. Additionally, the Company granted options to purchase a total
of 400,000 shares at an exercise price of $3.90 per share to two consultants.
 
  Option activity is summarized as follows:

  The Company has shares exercisable within the plan of 440,000 and 1,167,795
at December 31, 1996 and 1997, respectively, at a weighted average exercise
price of $.53 and $.81 per share, respectively. The Company also has shares
exercisable outside the plan of 576,500 and 914,000 at December 31, 1996 and
1997, respectively, at a weighted average exercise price of $.64 and $.76 per
share, respectively. The fair value of options granted within the plan in
1995, 1996 and 1997 was $.12, $.27 and $.34 per share, respectively. The fair
value of options granted outside the plan in 1995, 1996 and 1997 was $.12,
$.27 and $.27 per share.
 
  The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" (APB 25) and related
Interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under FASB
Statement No. 123, "Accounting for Stock-Based Compensation" (Statement 123),
requires use of option valuation models that were not developed for use in
valuing employee stock options. Under APB 25, because the exercise price of
the Company's employee stock options equals the market price of the underlying
stock on the date of grant, no compensation expense is recognized.
 
  Pro forma information regarding net loss and loss per share is required by
Statement 123, and has been determined as if the Company had accounted for its
employee stock options under the fair value method of that Statement. The fair
value for these options was estimated at the date of grant using a minimum
value option pricing model with the following weighted-average assumptions for
1995, 1996 and 1997: risk-free interest rate of 6.5%; dividend yield of 0% and
a weighed-average expected life of the option of 5 years.
 
  The minimum value option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions.
 
  For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The
Company's pro forma information follows:

STOCK OPTIONS AND WARRANTS (CONTINUED)
 
  During the initial phase-in period, the effects of applying statement 123
for recognizing compensation cost may not be representative of the effects on
reported net loss or income for future years because the options in the
Incentive Stock Option Plans vest over several years and additional awards
will be made in the future.
   
  During 1995, the Company granted a consultant warrants to purchase 150,000
shares of common stock at an exercise price of $.60 per share for services
provided. The warrants are immediately exercisable and expire November 17,
2002. The warrants were valued at $15 and were charged to expense.

10. EMPLOYMENT AGREEMENTS
 
  In November 1996, the Company entered into Employment Agreements with its
President and Chief Executive Officer and its Chief Technology Officer. The
agreements provide for an annual base salary and a bonus and other
compensation as may be established from time to time by the Board of
Directors. As part of the agreements, the employees were each granted options
to purchase 2,000,000 shares of common stock at an exercise price of $.96. The
agreements contain provisions providing for the maintenance of confidentiality
of proprietary information of the Company and a two-year non-competition
clause in the event of termination of employment. The agreements may be
terminated by either parties for any reason at any time. If, however, the
employees are terminated by the Company without cause, the Company must pay
salary to the employees equal to the employees' then base salary for two
years.

11. SAVINGS AND RETIREMENT PLAN
 
  The Company has a savings and retirement plan covering all eligible
employees. The plan was adopted pursuant to 401(k) of the Internal Revenue
Code. Contributions to the plan are discretionary for the employees. The
Company does not make contributions to the plan.
 
12. ACQUISITION
 
  In December 1997, the Company acquired the outstanding common stock of
FreeMail, Inc. (FreeMail). The results of operations of the acquired business
are included in the accompanying financial statements since the date of
acquisition.
 
  The Company issued 125,000 shares of common stock, with a fair value of
$488, as consideration in connection with the acquisition. The Company will
pay a quarterly payment to the former shareholders of FreeMail as additional
contingent consideration equal to five percent of the gross collected revenue
derived by the Company from certain identified FreeMail products. The total
amounts of the quarterly payments shall not exceed $3,013. As of December 31,
1997, the Company did not record a liability relating to the FreeMail revenue
since no revenue was collected. The acquisition was accounted for as a
purchase. The inclusion of the FreeMail operating results for periods prior to
the date of acquisition would not have materially affected results of
operations.
 
13. RELATED PARTY TRANSACTIONS
 
  The Company's corporate in-house counsel owns 250,000 shares, and has been
granted warrants and options to purchase 450,000 shares of Company common
stock. During the years ended December 31, 1995, 1996 and 1997, the Company
incurred legal fees and expenses of approximately $0, $102 and $128,
respectively, to such counsel for services rendered in connection with
litigation and for general legal services.
 
  The Company's corporate counsel is Larkin, Hoffman, Daly & Lindgren, Ltd.
One of the partners of this firm is the father of the Company's President and
Chief Executive Officer and owns 250,000 shares of common stock of the Company
and has been granted an option to purchase 200,000 shares of the Company's
common stock. Additionally, Mr. Hoffman, a partner of this firm, is a director
of the Company and has been granted an option to purchase 75,000 shares of the
Company's common stock. During the years ended December 31, 1995, 1996 and
1997, the Company incurred legal fees and expenses of approximately $0, $75
and $157, respectively, to such counsel for services rendered in connection
with litigation and for general legal services.
       
  The Company's marketing services were performed by Kauffman Marketing Group,
Inc. from November 1995 to December 1997. The former President of Kauffman
Marketing Group, Inc. joined the Company as the Vice President of Strategic
Marketing & Communications in December 1997. During the years ended
December 31, 1995, 1996 and 1997, the Company incurred marketing expenses of
approximately $0, $318 and $1,634, respectively, to such firm for strategic
positioning and outside marketing services.
 
  Management believes the fees paid for all the above services rendered to the
Company were on terms at least as favorable to the Company as could have been
obtained from an unrelated party.
 
14. MAJOR CUSTOMERS
 
  In 1996 two customers accounted for 80%, in aggregate, of net sales. In 1997
three customers accounted for 24%, in aggregate, of net sales.
 
15. CONTINGENCY
 
  The Company is engaged in certain legal proceedings and claims arising in
the ordinary course of its business. The ultimate liabilities, if any, which
may result from these or other pending or threatened legal actions
 
                                     F-21
<PAGE>
 
   
against the Company cannot be determined at this time. However, it is the
opinion of management that facts known at the present time do not indicate
that there is a probability that such litigation with have a material effect
on the financial position, results of operations or liquidity of the Company.
    
16. SUBSEQUENT EVENT (UNAUDITED)
   
  On March 13, 1998, the Company purchased all of the outstanding capital
stock of 4-Sight Limited, a private limited company organized under the laws
of the United Kingdom ("4-Sight"), for $20 million in cash plus related
acquisition expenses of $500 and 2,500,000 shares of the Company's common
stock valued at $20,000. In addition, the former shareholders of 4-Sight will
be entitled to receive up to an additional 750,000 shares of the Company's
common stock in the event certain sales objectives are met over the next three
years. Specifically, 4-Sight's former shareholders shall be entitled to
receive an additional 625,000 shares of Common Stock if the cumulative Non-
US/Canada Revenues (defined below) for the period from March 13, 1998 to
March 13, 2001 equal or exceed $50,000,000; and they shall be entitled to
receive a further 125,000 shares of Common Stock if the cumulative Non-
US/Canada Revenues during the same three year period equal or exceed
$70,000,000. For the purpose of the foregoing, "Non-US/Canada Revenues" shall
mean the revenues attributable to customer sites located outside the United
States and Canada and receivable by the Company or any of its subsidiaries.
The shares to be issued as contingent consideration will result in the Company
recording additional goodwill, which will be amortized over its estimated
useful life.     
 
  The acquisition was accounted for under the purchase method of accounting
and, accordingly, the operating results of 4-Sight have been included in the
consolidated operating results since the date of acquisition.
 
  On acquisition, approximately $31,928 of goodwill was recorded, which is
being amortized on a straight-line basis over 5 years. The following table
shows the pro forma consolidated results of operations as if 4-Sight had been
acquired as of the beginning of the periods presented:

                        REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors
4-Sight Limited
 
  We have audited the accompanying consolidated balance sheets of 4-Sight
Limited as at August 31, 1996, September 30, 1996 and September 30, 1997, and
the related consolidated statements of operations, shareholders' equity and
cash flows for the year ended August 31, 1996, the month ended September 30,
1996 and the year ended September 30, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with United Kingdom auditing standards
which do not differ in any significant respect from those generally accepted
in the United States. Those standards require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of 4-Sight Limited at August 31, 1996, September 30, 1996 and September 30,
1997, and the consolidated results of its operations and its cash flows for
the year ended August 31, 1996, the month ended September 30, 1996 and the
year ended September 30, 1997 in conformity with accounting principles
generally accepted in the United States.

                           (US DOLLARS IN THOUSANDS)
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
DESCRIPTION OF BUSINESS
 
  4-Sight Limited ( the "Company") was incorporated in England and Wales in
April 1993. The Company's principal activity is the development, marketing and
worldwide distribution of computer software applications.
 
PRINCIPLES OF CONSOLIDATION
 
  The consolidated financial statements, which are prepared under United
States generally accepted accounting principles, include the financial
statements of the Company and all its subsidiaries (together, the "Group").
All inter-company accounts and transactions have been eliminated.
 
ESTIMATES
 
  The preparation of financial statements in conformity with United States
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of certain assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
Management believes that the estimates are reasonable.
 
GOODWILL
 
  Purchased goodwill is capitalized and amortized over its estimated useful
life.
 
CASH AND CASH EQUIVALENTS
 
  Cash and cash equivalents represent cash and short-term deposits with
maturities of less than three months at inception.
 
INVENTORIES
 
  Inventories are stated at the lower of cost, determined on the basis of the
first in, first out method, and market value.
 
PROPERTY AND EQUIPMENT
 
  Property and equipment is carried at cost. Depreciation is charged on a
straight-line basis over the expected useful lives of the assets. Depreciation
is provided at the following annual rates:
 
<TABLE>   
        <S>                                                 <C>
        Long leasehold buildings...........................   2%
        Fixtures and equipment.............................  25%
        Motor vehicles.....................................  25%
</TABLE>    
   
REVENUE RECOGNITION     
   
 Software sales     
   
  Revenue is recognised upon shipment of goods to the customer and
satisfaction of significant related obligations, if any.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                           (US DOLLARS IN THOUSANDS)
   
 Hardware sales     
   
  Revenue is recognised upon shipment of goods to the customer.     
   
 Services and royalty fees     
   
  Revenue is recognised in the period in which it is earned.     
 
RESEARCH AND DEVELOPMENT
 
  Expenditure on research and development is written off as incurred.
 
LEASES
 
  The cost of assets held under capital leases is capitalised within the
appropriate fixed asset category and depreciation is provided in accordance
with the accounting policy for the category of asset concerned. The interest
cost is charged over the term of the lease and the capital element of future
lease payments is shown on the balance sheet in liabilities as capital lease
obligations. The cost of operating leases is charged to income as incurred.
 
FOREIGN CURRENCY TRANSLATION
 
  The functional currency is UK sterling.
 
  Transactions in non-functional currencies are recorded at the rates ruling
at the date of the transactions. Gains and losses resulting from non-
functional currency translations, and the re-measurement of non-functional
currency balances are included in the determination of net income in the
period in which they occur, in accordance with the requirements of Statement
of Financial Accounting Standards No. 52, "Foreign Currency Translation".
 
  The financial statements of overseas subsidiaries are translated at the rate
of exchange ruling at the balance sheet date, and the resulting translation
adjustment is shown as a separate component of shareholders' equity.
       
NET INCOME (LOSS) PER ORDINARY SHARE
   
  In 1997, the Financial Accounting Standards Board issued Statement No. 128,
Earnings per Share (Statement 128). Statement 128 replaced the calculation of
primary and fully diluted earnings per share with basic and diluted earnings
per share. Unlike primary earnings per share, basic earnings per share
excludes any dilutive effects of options, warrants and convertible securities.
Diluted earnings per share is very similar to fully diluted earnings per share
under the previous rules. All earnings per share amounts for all periods have
been presented, and where necessary, restated to conform to the Statement 128
requirements.     
 
INCOME TAXES
 
  The Group accounts for income taxes by the liability method. Deferred income
taxes are provided for on all temporary differences between financial
reporting and tax bases of assets and liabilities.
          
INTERIM FINANCIAL INFORMATION     
   
  The accompanying consolidated financial statements as of December 31, 1997
and for the three month periods ended December 31, 1996 and 1997 are
unaudited. In the opinion of the management of the Company,

  None of the options were exercisable as at August 31, 1996, September 30,
1996 and September 30, 1997.     
 
  The Company accounts for options granted under these plans in accordance
with APB No. 25. Each stock option has an exercise price equal to or above the
market value on the date of grant and accordingly no compensation expense is
recorded for any stock option grants. No options were granted during the
period to September 30, 1997.
   
  The weighted average fair value of options granted at market price in the
year ended August 31, 1996 was 4.5p ($0.07). The determination of the fair
value of the stock options granted in 1996 was calculated using the Black
Scholes method based on (i) risk-free interest rates of 5.4%, (ii) expected
option lives of 6 years and (iii) dividend yield of 0%.     
   
  Pro forma information regarding net income and income per share is required
by Statement 123, and has been determined as if the Company had accounted for
its employee stock options under the fair value method of that Statement. For
the purposes of pro forma disclosure, the estimated fair value of the options
is amortized to expense over the options' vesting period. The Company's pro
forma information is as follows:

                                    PART II
 
                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Section 302A.521 of the Minnesota Business Corporation Act generally
provides for the indemnification of directors, officers and employees of a
corporation made or threatened to be made a party to a proceeding by reason of
the former or present official capacity of the person against judgments,
penalties and fines (including attorneys' fees and disbursements) where such
person, among other things, has not been indemnified by another organization,
acted in good faith, received no improper personal benefit, and with respect
to any criminal proceeding, had no reasonable cause to believe his conduct was
unlawful.
 
  Section 9.3 of the Company's Amended and Restated Articles of Incorporation
provide:
 
    9.3 Indemnification. A director of the Corporation shall not be
  personally liable to the Corporation or its shareholders for monetary
  damages for breach of fiduciary duty as a director, except for (i)
  liability based on a breach of the duty of loyalty to the Corporation or
  the shareholders (ii) liability for acts or omissions not in good faith or
  that involve intentional misconduct or a knowing violation of law; (iii)
  liability under Minnesota Statutes Section 302A.559 or 80A.23; or (iv)
  liability for any transaction from which the director derived an improper
  personal benefit. If Chapter 302A, the Minnesota Business Corporation Act,
  is hereafter amended to authorize the further elimination or limitation of
  the liability of directors, then the liability of a director of the
  Corporation, in addition to the limitation on personal liability provided
  herein, shall be limited to the fullest extent permitted by the amended
  Chapter 302A, the Minnesota Business Corporation Act. Any repeal or
  modification of this Section 9.3 by the shareholders of the Corporation
  shall be prospective only, and shall not adversely affect any limitation on
  the personal liability of a director of the Corporation at the time of such
  repeal or modification.

ITEM 22. UNDERTAKINGS.
 
  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 under 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 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 their counsel the matter has been settled by controlling
precedent, submit to court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
       
       
       
  The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 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.
 
  The undersigned Registrants 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
this Registration Statement when it became effective.
 
                                     II-3

  The undersigned registrant hereby undertakes:     
     
    (1) To file, during any period in which offers or sales are being made, a
  post-effective amendment to this registration statement:     
       
      (i) To include any prospectus required by section 10(a)(3) of the
    Securities Act of 1933;     
       
      (ii) To reflect in the prospectus any facts or events arising after
    the effective date of the registration statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in the registration statement. Notwithstanding the foregoing, any
    increase or decrease in volume of securities offered (if the total
    dollar value of securities offered would not exceed that which was
    registered) and any deviation from the low or high end of the estimated
    maximum offering range may be reflected in the form of prospectus filed
    with the Commission pursuant to Rule 424(b) ((S) 230.424(b) of this
    chapter) if, in the aggregate, the changes in volume and price
    represent no more than a 20% change in the maximum aggregate offering
    price set forth in the "Calculation of Registration Fee" table in the
    effective registration statement;     
       
      (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in the registration statement or
    any material change to such information in the registration statement;
           
    (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, 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.     
     
    (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.     
     
    (4) If the registrant is a foreign private issuer, to file a post-
  effective amendment to the registration statement to include any financial
  statements required by (S) 210.3-19 of this chapter at the start of any
  delayed offering or throughout a continuous offering. Financial statements
  and information otherwise required by Section 10(a)(3) of the Act need not
  be furnished, provided that the registrant includes in the prospectus, by
  means of a post-effective amendment, financial statements required pursuant
  to this paragraph (a)(4) and other information necessary to ensure that all
  other information in the prospectus is at least as current as the date of
  those financial statements. Notwithstanding the foregoing, with respect to
  registration statements on Form F-3 ((S) 239.33 of this chapter), a post-
  effective amendment need not be filed to include financial statements and
  information required by Section 10(a)(3) of the Act or (S) 210.3-19 of this
  chapter if such financial statements and information are contained in
  periodic reports filed with or furnished to the Commission by the
  registrant pursuant to section 13 or section 15(d) of the Securities
  Exchange Act of 1934 that are incorporated by reference in the Form F-3.

     (i)     The separate existence of FreeMail shall cease, and FreeMail shall

             the following conversion formula: Twenty Five Thousand (25,000)
             divided by the sum of the number of outstanding shares of FreeMail.
             Such Netco common shares will be distributed to the persons
             (shareholders) named and in the amounts set forth on Schedule
             1.3(a) to this Agreement. No fractional shares of Netco shall be

     (i)     Subject to the terms of this Section 1.3(b), and subject to Netco
             and NAC's right of offset as described in Section 8.3 below, Netco
             shall pay to the Shareholders the additional contingent
             consideration ("Additional Contingent Consideration") as, and not

     (ii)    Netco shall pay allocably to the Shareholders as Additional
             Contingent Consideration an aggregate quarterly sum (the "Quarterly
             Payment") equal to five percent (5%) of the gross collected revenue
             derived by Netco and/or NAC from the items listed on Schedule
             1.3(b) to this Agreement ("FreeMail Product") provided, Netco shall
             have no obligation to sell or otherwise commercialize such items
             except as it may determine to do so in its sole judgment.

     (iii)   The Quarterly Payment shall be allocated among the Shareholders
             ratably to their receipt of Netco common shares according to
             Schedule 1.3(a) to this Agreement.

     (iv)    The total amount of Quarterly Payments payable by Netco in
             accordance with this Section 1.3(b) shall not exceed Three Million

     (v)     The Quarterly Payments will be made within thirty (30) days
             following the end of each calendar quarter. At the time of each
             Quarterly Payment, Netco shall furnish to a duly appointed
             representative selected by a majority of the Shareholders a
             reasonably detailed statement showing (a) the name of Netco's
             customer respecting whom any calculation and payment of Quarterly
             Payment is due under this Agreement, (b) the amount of gross
             revenue billed for FreeMail Product each such customer during the
             calendar quarter for which such calculation is made, (c) 

                                       2.
<PAGE>
 
             the amount of gross revenue collected from each such customer for
             FreeMail Product during the calendar quarter for which such
             calculation is made, (d) the amount, if any, of uncollectible
             receivables written off for each such customer for FreeMail
             Product, and (e) a reconciliation showing the amount remaining
             receivable from each such customer for FreeMail Product. The duly
             appointed representative of a majority of the FreeMail Holders, or
             its agent and/or accountant shall have the right, exercisable no
             more often than once each year, to examine Netco's records during
             normal business hours, upon ten day's prior written notice, to
             confirm the adequacy and accuracy of the Quarterly Payments and of
             the related quarterly statements since the then most recent of (x)
             the Effective Date of the Merger, (y) the last such examination, or
             (y) twenty four (24) months. Netco shall promptly pay any
             deficiency revealed by such examination together with simple
             interest at the rate of eight percent (8%) per annum from date on
             which any such deficient amounts first became payable through the
             date of payment. In addition, if such deficiencies exceed five
             percent (5%) of the total amount owned for the period to which the
             examination relates, Netco shall also pay all reasonable costs and
             expenses incurred by the FreeMail Holders, and by their duly
             appointed representative, in the conduct of such examination.

     (c)     Status of FreeMail Securities After the Merger. After the Effective
             ---------------------------------------------- 
Date of the Merger:

     (i)     Until surrendered, each outstanding certificate which prior to the
             Effective Date of the Merger represented common stock of FreeMail
             shall be deemed for all corporate purposes (subject to the further
             provisions of this Section 1.3(c)(i) and Section 1.3(d)) to
             evidence the number of Common Shares of Netco into which they are
             converted in accordance with the terms of this Agreement. After the
             Effective Date of the Merger, there shall be no further registry or
             transfer on FreeMail's records of its common stock which had been
             outstanding immediately prior to the Effective Date of the Merger,
             and, if certificates representing such shares are presented to
             Netco and are reflected on FreeMail's Stock register as validly
             issued and outstanding, the shares represented by such certificates
             shall be treated in accordance with the above conversion terms of
             this Agreement. No dividends or distributions shall be paid to
             persons entitled to receive certificates for shares of Netco Common
             Shares until such persons shall have surrendered their certificates
             representing FreeMail common stock; provided, however, that when
             such certificates have been so surrendered in exchange for
             certificates of Netco Common Shares, there shall be paid to the
             holders thereof, but without interest thereof, all dividends and
             other distributions payable subsequent to and in respect of record
             dates after the Effective Date of the Merger on the Netco Common
             Shares for which such certificates shall have been so exchanged.

     (ii)    If any certificate representing shares of FreeMail common stock (or
             the right to purchase FreeMail common stock) is surrendered in
             exchange for Netco Common Shares and the certificate for such Netco
             Common Shares is to be issued in a name 

                                       3.
<PAGE>
 
             other than that in which the certificate surrendered for exchange
             is registered, it shall be a condition of such exchange that the
             certificate so surrendered shall be properly endorsed or otherwise
             in proper form for transfer and that the person requesting such
             exchange shall pay to Netco or its transfer agent any transfer or
             other taxes required by reason of the issuance of Common Shares in
             any name other than that of the registered holder of the
             certificate for shares, options or warrants so surrendered.

     1.4     Tax Considerations. Neither Party makes any representation
             ------------------   
regarding the taxability of the transaction contemplated by this Agreement or
the Merger Plan.

             Outstanding.
             ----------- 

     (i)     As of the date hereof, the authorized capital stock of Netco

             subscriptions, options, warrants or other rights of any kind to
             acquire any additional shares of capital stock of Netco, or other
             instruments or securities convertible into or exchangeable for, or
             which otherwise confer on the holder thereof any right to acquire,

governmental authority relating to the operation, conduct or ownership of the
property or business of Netco, which violation might have a material adverse
effect, individually or in the aggregate, on the financial condition, the
business operations, or the business prospects of Netco, or which may be
reasonably expected to impair the consummation of the transactions contemplated

Shareholders agree to allow NAC thirty (30) business days to review and approve
such returns, approval of which will not unreasonably be withheld.

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

     8.8       Headings.  The descriptive headings of the several Articles and
               --------                                                       
Sections of this Agreement, of the Plan of Merger, and of the several Schedules
and Exhibits to this Agreement are inserted for convenience only and do not
constitute a part of this Agreement.

     8.9       Counterparts.  This Agreement may be executed in one or more
               ------------                                                
counterparts, all of which shall be considered one and the same agreement, and
shall become effective when one or more of the counterparts have been signed by
each of the parties hereto and delivered to the other party.

     8.10      Time of the Essence.  Time is of the essence of this Agreement.
               -------------------                                            

     8.11      Severability.  In case any provision of this Agreement shall be
               ------------                                                   
invalid, illegal or unenforceable, it shall, to the extent possible, be modified
in such manner as to be valid, legal and enforceable but so as most nearly to
retain the intent of the parties.  If such modification is not possible, such
provision shall be severed from this Agreement.  In either case the validity,
legality and enforceability of the remaining provisions of this Agreement shall
not in any way be affected or impaired thereby.

     8.12      Construction.  The parties have participated jointly in the

question of intent or interpretation arises, this Agreement shall be construed

arise favoring or disfavoring any party by virtue of the authorship of any of
the provisions of this Agreement.  Any reference to any federal, state, local or
foreign statute shall be deemed to refer to all rules and regulations
promulgated thereunder, unless the context requires otherwise.  The word
"including" means including, without limitation.  The parties intend that each
representation, warranty and covenant contained herein shall have independent
significance.  If any party has breached any representation, warranty or
covenant contained herein in any respect, the fact that there exists another
representation, warranty or covenant relating to the same subject matter
(regardless of the relative levels of specificity) that the party has not
breached shall not detract from or mitigate the fact the party is in breach of
the first representation, warranty or covenant.

     8.13      Merger and Integration.  This Agreement and the Merger Plan
               ----------------------

all prior negotiations and agreements are merged herein and superseded by this
Agreement and the Merger Plan.

                                  WAM!NET INC.

     The undersigned, the President of WAM!NET Inc., a Minnesota corporation
(the "Corporation"), does hereby certify that pursuant to the annual meeting of
shareholders of the Corporation held May 30, 1998, the following resolution was
adopted by the shareholders of the Corporation in accordance with the
application with the applicable provisions of Minnesota Statutes:

                      Resolution Authorizing Amendment of
                      ------------------------------------
                           Articles of Incorporation
                           -------------------------

     RESOLVED, that Article 6 of the Corporation's Articles of Incorporation be
     amended to read as follows:

                                   ARTICLE 6.

                                     STOCK

               6.1)  Capitalization.  The aggregate number of shares of capital
                     --------------                                            
          stock that the Corporation has authority to issue shall be five
          hundred million (500,000,000) shares, which are hereby designated as
          and shall consist of (a) four hundred ninety million (490,000,000)
          shares of common stock, with a par value of One Cent ($.01) per share
          ("Common Stock"); (b) one hundred thousand (100,000) shares of Class A
          preferred stock ("Class A Preferred Stock"); and (c) nine million nine
          hundred thousand (9,900,000) shares of undesignated stock.  The Board
          of Directors of the Corporation is authorized to establish from the
          undesignated stock, by resolution adopted and filed in the manner
          provided by law, one or more classes or series of shares, to designate
          each such class or series (which may include but is not limited to
          designation as additional Common Stock), and to fix the relative
          rights and preferences of each such class or series.

               6.2)  Class A Preferred Stock.  The express terms and provisions
                     -----------------------                                   
          of the shares classified and designated as Class A Preferred Shares
          are as follows:

               (a) Designation and Amount.  Each share of Class A Preferred
                   ----------------------                                  
               Stock shall have a par value of Ten Dollars ($10.00) per share.
               The number of shares of Class A Preferred Stock may be increased
               or decreased by resolution of the Board of Directors; provided,
               that, no decrease shall 
<PAGE>
 
               reduce the number of shares of Class A Preferred Stock to a
               number less than the number of shares then outstanding, plus the
               number of shares of Class A Preferred Stock, if any, reserved for
               issuance upon the exercise of outstanding options, rights or
               warrants or upon the conversion of any outstanding securities
               issued by the Company convertible into Class A Preferred Stock.

               (b)  Dividends and Distributions.
                    --------------------------- 

                    (1)  The holders of shares of Class A Preferred Stock, in
                         preference to the holders of Common Stock of the
                         Company, shall be entitled to receive, when, as and if
                         declared by the Board of Directors of the Company (the
                         "Directors"), a dividend (the "Quarterly Dividend") in
                         the amount of Seventeen and One-half Cents ($.175) per
                         share payable out of the net earnings of the Company
                         constituting funds legally available for the purpose.
                         The Quarterly Dividend shall begin to accrue on January
                         1, 1997, and shall be payable in cash on the first day
                         of March, June, September and December in each year
                         (each such date being referred to herein as a
                         "Quarterly Dividend Payment Date"), commencing on the
                         first Quarterly Dividend Payment Date after the first
                         issuance of a share or fraction of a share of Class A
                         Preferred Stock.  If the net earnings in any year are
                         not sufficient to pay the Quarterly Dividend, either in
                         whole or in part, then any unpaid portion of such
                         dividend will become a charge against the net earnings
                         of the Company, and will be paid in full out of the net
                         earnings of the Company in subsequent years before any
                         dividends are paid on the Common Stock of the Company
                         in those years.  No dividends will be paid or set apart
                         for payment on the Common Stock, no distribution will
                         be made on the Common Stock, and no shares of Common
                         Stock will be redeemed, retired or otherwise acquired
                         for valuable consideration unless all theretofore
                         unpaid Quarterly Dividends have been declared, and the
                         Company has paid those dividends or has set aside a sum
                         sufficient to pay them.

                    (2)  Dividends shall begin to accrue and accumulate on
                         outstanding shares of Class A Preferred Stock from the
                         Quarterly Dividend Payment Date next preceding the date
                         of issue of such shares, in which case dividends on
                         such shares shall begin to accrue from the date of
                         issue of such shares, or unless the date of issue is a
                         Quarterly Dividend 
<PAGE>
 
                         Payment Date or is a date after the record date for the
                         determination of holders of shares of Class A Preferred
                         Stock entitled to receive Quarterly Dividends and
                         before such Quarterly Dividend Payment Date, in either
                         of which events such Quarterly Dividends shall begin to
                         accrue and accumulate from such Quarterly Dividend
                         Payment Date. Accrued but unpaid Quarterly Dividends
                         shall not bear interest. Dividends paid on the shares
                         of Class A Preferred Stock in an amount less than the
                         total amount of Quarterly Dividends then accrued and
                         payable shall be allocated pro rata on a share-by-share
                         basis among all such shares of Class A Preferred Stock
                         then outstanding. The Directors may fix a record date
                         for the determination of holders of shares of Class A
                         Preferred Stock entitled to receive payment of a
                         dividend or distribution declared thereon, which record
                         date shall be no more than sixty (60) days prior to the
                         date fixed for the payment thereof.

               (c) Voting Rights.  The holders of shares of Class A Preferred
                   -------------                                             
               Stock shall have the following voting rights:

                    (1)  Each share of Class A Preferred Stock shall entitle the
                         holder thereof to one (1) vote for each share of Class
                         A Preferred Stock standing in the name of the holder on
                         the books of the Company.  The holders of Class A
                         Preferred Stock, voting separately as a class, shall be
                         entitled to elect a majority of the Directors.  The
                         right to elect Directors may be exercised at any annual
                         meeting of the stockholders of the Company, at any
                         special meeting held in place of an annual meeting, or
                         at a special meeting called to elect directors.  The
                         right to elect directors shall continue until December
                         31, 1999, and then expire.  The directors elected by
                         the Class A Preferred Stock shall serve until the next
                         annual or special meeting of the stockholders of the
                         Company and until their respective successors have been
                         elected by the holders of Class A Preferred Stock and
                         have been qualified.  The term of office of any person
                         elected as a director by the holders of Class A
                         Preferred Stock shall terminate on December 31, 1999.
                         The vacancies created thereby may be filled by
                         resolution of the remaining Directors who shall have
                         been elected by a vote of the holders of the Common
                         Stock of the Company.  If the office of a director
                         elected by the holders of Class A Preferred Stock is
                         vacant prior to December 31, 1999, due to resignation,
                         removal or death, the vacancy shall be filled

                         by the majority vote of the directors then in office,
                         even if less than a quorum, upon the recommendation of
                         the remaining director or directors who were elected by
                         the holders of the Class A Preferred Stock. If the
                         office of a director who was elected by the holders of
                         Common Stock is vacant prior to December 31, 1999, due
                         to resignation, removal or death, the vacancy shall be
                         filled by the majority vote of the directors then in
                         office, even if less than a quorum, upon the
                         recommendation of the remaining director or directors
                         who were elected by the holders of the Common Stock. If
                         the vacancy is not so filled within forty (40) days
                         after the creation of the vacancy, a special meeting of
                         the holders of Preferred Stock and/or Common Stock
                         shall be called and the vacancy or vacancies shall be
                         filled at that meeting.

                         provided by law, holders of Class A Preferred Stock
                         shall have no special voting rights and their consent,
                         as a separate class, shall not be required (except to
                         the extent they are entitled to vote with holders of
                         Common Stock as set forth herein) for taking any
                         corporate action.

                                    entitled;

                              c.    redeem or purchase or otherwise acquire for

                                    up) with the Class A Preferred Stock, except
                                    in accordance with a purchase offer made in
                                    writing or by publication (as determined by
<PAGE>
 
                                    the Board of Directors) to all holders of

                                    Directors, after consideration of the
                                    respective annual dividend rates and other
                                    relative rights and preferences of the
                                    respective series and classes, shall

                                    series or classes.

                    (2)  The Company shall not permit any subsidiary of the
                         Company to purchase or otherwise acquire for
                         consideration any shares of stock of the Company unless
                         the Company could, under Section 6.2(d)(1), purchase or
                         otherwise acquire such shares at such time and in such
                         manner.

               (e) Liquidation, Dissolution or Winding Up.  Upon any voluntary
                   --------------------------------------

               affairs of the Company, no distribution shall be made (a) to the
               holders of shares of stock ranking junior (either as to dividends
               or upon liquidation, dissolution or winding up) to the Class A
               Preferred Stock, or (b) to the holders of shares of stock ranking

               dissolution or winding up) with the Class A Preferred Stock
               unless each holder of Class A Preferred Stock has received in
               cash out of the assets of the Company, whether from capital or
               earnings, available for distribution to the shareholders of the
               Company, before any amount is paid to the holders of Common
               Stock, the sum of Ten Dollars ($10.00) per share for each share
               of Class A Preferred Stock held by the holder, plus an amount
               equal to the sum of all accumulated and unpaid dividends to the
               date affixed for the payment of the distribution on the shares of

               by the Company of all or substantially all of its assets shall
               not, for the purposes of determining preferences and liquidation,
               be deemed to be a liquidation, dissolution or winding up of the
               Company.

               (f) Preemptive Rights.  No holder of any shares of Class A
                   -----------------                                     
               Preferred Stock shall be entitled as such, as a matter of right,
               to subscribe for, purchase or receive any part of any class
               whatsoever, or of securities convertible into or exchangeable for
               any stock or any class whatsoever, whether now or hereafter
               authorized or whether issued for cash or other consideration or
               by way of a dividend.

               (g) Mandatory Redemption.  Unless earlier redeemed or acquired in
                   --------------------                                         
               whole or in part by the Company with the consent of the holder,
               the shares

               of Class A Preferred Stock that remain issued and outstanding
               shall expire and shall be automatically redeemed on December 31,
               1999, at par value, plus an amount equal to all accumulated and
               unpaid dividends, if any, due with respect to the Class A
               Preferred Stock (collectively, the "Redemption Price").
               Redemption shall be in cash out of any funds legally available
               for the redemption of the Class A Preferred Stock.

               (h) Rank.  The Class A Preferred Stock shall rank, with respect
                   ----                                                       
               to the payment of dividends and the distribution of assets,
               senior to all other classes and series of preferred stock.

               (i) Reacquired Shares.  Any shares of Class A Preferred Stock
                   -----------------                                        
               purchased or otherwise acquired by the Company in any manner
               whatsoever shall be retired and canceled promptly after the
               acquisition thereof.  All such shares shall upon their
               cancellation become authorized but unissued shares of
               undesignated stock and may be reissued subject to the conditions
               and restrictions on issuance in the Articles of Incorporation, or
               in any other Certificate of Designations creating another class
               or series of stock or as otherwise required by law.

               (j) Amendment.  If any proposed amendment to these Articles of
                   ---------                                                 
               Incorporation would alter or change the preferences, special
               rights or powers given to the Class A Preferred Stock so as to
               affect the Class A Preferred Stock adversely, or would authorize
               the issuance of a class or classes of stock having preferences or
               rights with respect to dividends or dissolution or the
               distribution of assets that would be superior to the preferences
               or rights of the Class A Preferred Stock, then the holders of the
               Class A Preferred Stock shall be entitled to vote as a series
               upon such amendment, and the affirmative vote of two-thirds of
               the outstanding shares of Class A Preferred Stock shall be
               necessary to the adoption thereof, in addition to such other vote
               as may be required by law.

               6.3)  Preemptive Rights.  Shareholders shall not have any
                     -----------------                                  
          preemptive or preferential rights for or to shares of this
          Corporation, whether now or hereafter authorized, or to any
          obligations convertible into shares of this Corporation, or to any
          options, warrants or other right to acquire shares of this
          Corporation, or to any subscription or right of subscription therefor,
          except such, if any, as the Board of Directors in its sole discretion
          may determine from time to time, and at such price or terms as the
          Board of Directors may fix.  The Board of Directors may, at any time
          and from time to time, issue and sell for such consideration as may be
          permitted by law and these Articles of Incorporation, any or all of
          the authorized shares of the Corporation not then issued and any and
          all of any stock of any class or series that may hereafter be
          authorized.
<PAGE>
 
               6.4)  Issuance of Shares.  Subject to this Article 6, the Board
                     ------------------                                       
          of Directors may issue any or all shares of the Corporation authorized
          by these Articles and not already issued, including any shares
          previously issued and reacquired by the Corporation.  Upon approval by
          the Board of Directors, shares may be issued (i) for any consideration
          determined appropriate by the Board of Directors, or (ii) for no
          consideration in order to effectuate share conversions, dividends or
          splits, including reverse splits.

               6.5)  Issuance of Rights to Acquire Shares.  Subject to Section
                     ------------------------------------                     
          6.4, the Board of Directors may issue rights to purchase shares of the
          Corporation, and shall fix the terms, provisions and conditions of
          such rights to purchase, including the conversion basis and the price
          at which shares may be purchased or subscribed for.  Shares to be
          issuable upon the exercise of all outstanding rights to purchase,
          including such rights to be issued, must be authorized by these
          Articles and not already issued.

     IN WITNESS WHEREOF, I have subscribed my name this 16th day of June, 1998.

                                  ARTICLE 6.

                                     STOCK

     6.1)  Capitalization. The aggregate number of shares of stock that the 
           --------------
Corporation has authority to issue shall be one hundred million (100,000,000) 
shares, which shall consist of (a) ninety million (90,000,000) shares of common
stock, with a par value of One Cent ($.01) per share ("Common Stock"); (b) one 
hundred thousand (100,000) shares of Class A preferred stock ("Class A Preferred
Stock"); and (c) nine million nine hundred thousand (9,900,000) shares of
undesignated stock. The Board of Directors of the Corporation is authorized to
establish from the undesignated stock, by resolution adopted and filed in the
manner provided by law, one or more classes or series of shares, to designate
each such class or series (which may include but is not limited to designation
as additional Common Stock), and to fix the relative rights and preferences of
each such class or series.

     6.2)  Class A Preferred Stock. The express terms and provisions of the 
           -----------------------
shares classified and designated as Class A Preferred Shares are as follows:

     (a)   Designation and Amount. Each share of Class A Preferred Stock shall
           ----------------------
     have a par value of Ten Dollars ($10.00) per share. The number of shares of
     Class A Preferred Stock may be increased or decreased by resolution of the
     Board of Directors; provided, that, no decrease shall reduce the number of
     shares of Class A Preferred Stock to a number less than the number of
     shares then outstanding, plus the number of shares of Class A Preferred
     Stock, if any, reserved for issuance upon the exercise of outstanding
     options, rights or warrants or upon the conversion of any outstanding
     securities issued by the Company convertible into Class A Preferred Stock.

     (b)   Dividends and Distributions.
           ---------------------------

           (1)  The holders of shares of Class A Preferred Stock, in preference
                to the holders of Common Stock of the Company, shall be entitled
                to receive, when, as and if declared by the Board of Directors
                of the Company (the "Directors"), a dividend (the "Quarterly
                Dividend") in the amount of Seventeen and One-half Cents ($.175)
                per share payable out of the net earnings of the Company
                constituting funds legally available for the purpose. The
                Quarterly Dividend shall begin to accrue on January 1, 1997, and
                shall be payable in cash on the first day of March, June,
                September and December in each year (each such date being
                referred to herein as a "Quarterly Dividend Payment Date"),
                commencing on the first Quarterly Dividend Payment Date after
                the first issuance of a share or fraction of a share of Class A
                Preferred Stock. If the net earnings in any year are not
                sufficient to pay the Quarterly Dividend, either in whole or in
                part, then any unpaid portion of such dividend will become a
                charge against the net earnings of the Company, and will be paid
                in full out of the net earnings of the Company in subsequent
                years before any dividends are



<PAGE>
 
          paid on the Common Stock of the Company in those years. No dividends
          will be paid or set apart for payment on the Common Stock, no
          distribution will be made on the Common Stock, and no shares of Common
          Stock will be redeemed, retired or otherwise acquired for valuable
          consideration unless all theretofore unpaid Quarterly Dividends have
          been declared, and the Company has paid those dividends or has set
          aside a sum sufficient to pay them.

     (2)  Dividends shall begin to accrue and accumulate on outstanding shares
          of Class A Preferred Stock from the Quarterly Dividend Payment Date
          next preceding the date of issue of such shares, in which case
          dividends on such shares shall begin to accrue from the date of issue
          of such shares, or unless the date of issue is a Quarterly Dividend
          Payment Date or is a date after the record date for the determination
          of holders of shares of Class A Preferred Stock entitled to receive
          Quarterly Dividends and before such Quarterly Dividend Payment Date,
          in either of which events such Quarterly Dividends shall begin to
          accrue and accumulate from such Quarterly Dividend Payment Date.
          Accrued but unpaid Quarterly Dividends shall not bear interest.
          Dividends paid on the shares of Class A Preferred Stock in an amount
          less than the total amount of Quarterly Dividends then accrued and
          payable shall be allocated pro rata on a share-by-share basis among
          all such shares of Class A Preferred Stock then outstanding. The
          Directors may fix a record date for the determination of holders of
          shares of Class A Preferred Stock entitled to receive payment of a
          dividend or distribution declared thereon, which record date shall be
          no more than sixty (60) days prior to the date fixed for the payment
          thereof.

(c)  Voting Rights.  The holders of shares of Class A Preferred Stock shall have
     -------------
the following voting rights:


     (1)  Each share of Class A Preferred Stock shall entitle the holder thereof
          to one (1) vote for each share of Class A Preferred Stock standing in
          the name of the holder on the books of the Company. The holders of
          Class A Preferred Stock, voting separately as a class, shall be
          entitled to elect a majority of the Directors. The right to elect
          Directors may be exercised at any annual meeting of the stockholders
          of the Company, at any special meeting held in place of an annual
          meeting, or at a special meeting called to elect directors. The right
          to elect directors shall continue until December 31, 1999, and then
          expire. The directors elected by the Class A Preferred Stock shall
          serve until the next annual or special meeting of the stockholders of
          the Company and until their respective successors have been elected by
          the holders of Class A Preferred Stock and have been qualified. The
          term of office of any person elected as a director by the holders of
          Class A Preferred Stock shall terminate on December 31, 1999.





<PAGE>
 
          The vacancies created thereby may be filled by resolution of the
          remaining Directors who shall have been elected by a vote of the
          holders of the Common Stock of the Company. If the office of a
          director elected by the holders of Class A Preferred Stock is vacant
          prior to December 31, 1999, due to resignation, removal or death, the
          vacancy shall be filled by the majority vote of the directors then in
          office, even if less than a quorum, upon the recommendation of the
          remaining director or directors who were elected by the holders of the
          Class A Preferred Stock. If the office of a director who was elected
          by the holders of Common Stock is vacant prior to December 31, 1999,
          due to resignation, removal or death, the vacancy shall be filled by
          the majority vote of the directors then in office, even if less than a
          quorum, upon the recommendation of the remaining director or directors
          who were elected by the holders of the Common Stock. If the vacancy is
          not so filled within forty (40) days after the creation of the
          vacancy, a special meeting of the holders of Preferred Stock and/or
          Common Stock shall be called and the vacancy or vacancies shall be
          filled at that meeting.

     (2)  In addition to the right to elect a majority of the Directors as
          provided in Section 6.2(c)(1), the holder of each share of Class A
          Preferred Stock shall be entitled to one (1) vote, voting together
          with the holders of Common Stock as a single class, on all matters,
          excluding the election of Directors, submitted to the vote of
          shareholders of the Company.

     (3)  Except as otherwise provided in Section 6.2(c) or in Section 6.2(j)
          hereof, or in any Certificate of Designations creating another class
          or series of preferred stock, or in any similar stock of the Company
          hereafter created, or by law, the holders of shares of Class A
          Preferred Stock and the holders of shares of Common Stock and any
          other capital stock of the Company having general voting rights shall
          vote together as one class on all matters submitted to a vote of
          stockholders of the Company.

     (4)  Except as expressly set forth herein, or as otherwise provided by law,
          holders of Class A Preferred Stock shall have no special voting rights
          and their consent, as a separate class, shall not be required (except
          to the extent they are entitled to vote with holders of Common Stock
          as set forth herein) for taking any corporate action.

(d)  Certain Restrictions
     --------------------

     (1)  Whenever Quarterly Dividends or distributions payable on Class A
          Preferred Stock as provided in Section 6.2(b) are in arrears,
          thereafter and until all accrued and unpaid Quarterly Dividends and
          distributions, whether or not declared, on shares of Class A Preferred
          Stock outstanding shall have been paid in full, the Company shall not,
          without the express





<PAGE>
 
          affirmative unanimous approval of the Directors elected by holders of 
          the Class A Preferred Stock:

          a.   declare or pay dividends, or make any other distributions, on any
               shares of stock ranking junior (either as to dividends or upon
               liquidation, dissolution or winding up) to the Class A Preferred
               Stock;

          b.   declare or pay dividends, or make any other distributions, on any
               shares of stock ranking on a parity (either as to dividends or
               upon liquidation, dissolution or winding up) with the Class A
               Preferred Stock, except dividends paid ratably on the Class A
               Preferred Stock and all such parity stock on which dividends are
               payable or in arrears in proportion to the total amounts to which
               the holders of all such shares are then entitled;

          c.   redeem or purchase or otherwise acquire for consideration shares
               of any stock of the Company ranking junior (either as to
               dividends or upon liquidation, dissolution or winding up) to the
               Class A Preferred Stock, provided that the Company may at any
               time redeem, purchase or otherwise acquire shares of any such
               junior stock in exchange for shares of any stock of the Company
               ranking junior (as to dividends and upon dissolution, liquidation
               and winding up) to the Class A Preferred Stock; or

          d.   redeem or purchase or otherwise acquire for consideration any
               shares of Class A Preferred Stock, or any shares of stock ranking
               on a parity (either as to dividends or upon liquidation,
               dissolution or winding up) with the Class A Preferred Stock,
               except in accordance with a purchase offer made in writing or by
               publication (as determined by the Board of Directors) to all
               holders of such shares upon such terms as the Board of Directors,
               after consideration of the respective annual dividend rates and
               other relative rights and preferences of the respective series
               and classes, shall determine in good faith will result in fair
               and equitable treatment among the respective series or classes.

     (2)  The Company shall not permit any subsidiary of the Company to purchase
          or otherwise acquire for consideration any shares of stock of the
          Company unless the Company could, under Section 6.2(d)(1), purchase or
          otherwise acquire such shares at such time and in such manner.

(e)  Liquidation, Dissolution or Winding Up. Upon any voluntary or involuntary 
     --------------------------------------
liquidation, dissolution or winding up of the affairs of the Company, no 
distribution shall be made (a) to the holders of shares of stock ranking junior 
(either as to dividends or upon liquidation, dissolution or winding up) to the 
Class A Preferred Stock, or (b) to the






<PAGE>
 
holders of shares of stock ranking on a parity (either as to dividends or upon 
liquidation, dissolution or winding up) with the Class A Preferred Stock unless 
each holder of Class A Preferred Stock has received in cash out of the assets of
the Company, whether from capital or earnings, available for distribution to the
shareholders of the Company, before any amount is paid to the holders of Common 
Stock, the sum of Ten Dollars ($10.00) per share for each share of Class A 
Preferred Stock held by the holder, plus an amount equal to the sum of all 
accumulated and unpaid dividends to the date affixed for the payment of the 
distribution on the shares of Class A Preferred Stock held by the holder. The 
sale or transfer by the Company of all or substantially all of its assets shall 
not, for the purposes of determining preferences and liquidation, be deemed to 
be a liquidation, dissolution or winding up of the Company.

(f)  Preemptive Rights. No holder of any shares of Class A Preferred Stock shall
     ------------------   
be entitled as such, as a matter of right, to subscribe for, purchase or receive
any part of any class whatsoever, or of securities convertible into or 
exchangeable for any stock or any class whatsoever, whether now or hereafter 
authorized or whether issued for cash or other consideration or by way of a 
dividend.

(g)  Mandatory Redemption. Unless earlier redeemed or acquired in whole or in 
     --------------------  
part by the Company with the consent of the holder, the shares of Class A 
Preferred Stock that remain issued and outstanding shall expire and and shall be
automatically redeemed on December 31, 1999, at par value, plus an amount equal
to all accumulated and unpaid dividends, if any, due with respect to the Class A
Preferred Stock (collectively, the "Redemption Price"). Redemption shall be in
cash out of any funds legally available for the redemption of the Class A
Preferred Stock.

(h)  Rank. The Class A Preferred Stock shall rank, with respect to the payment 
     ---- 
of dividends and the distribution of assets, senior to all other classes and 
series of preferred stock.

(i)  Reacquired Shares. Any shares of Class A Preferred Stock purchased or 
     -----------------
otherwise acquired by the Company in any manner whatsoever shall be retired and 
canceled promptly after the acquisition thereof. All such shares shall upon
their cancellation become authorized but unissued shares of undesignated stock
and may be reissued subject to the conditions and restrictions on issuance in
the Articles of Incorporation, or in any other Certificate or Designations
creating another class or series of stock or as otherwise required by law.

(j)  Amendment. If any proposed amendment to these Articles of Incorporation 
     --------- 
would alter or change the preferences, special rights or powers given to the 
Class A Preferred Stock so as to affect the Class A Preferred Stock adversely, 
or would authorize the issuance of a class or classes of stock having 
preferences or rights with respect to dividends or dissolution or the 
distribution of assets that would be superior to the preferences or rights of 
the Class A Preferred Stock, then the holders of the Class A Preferred Stock 
shall be entitled to vote as a series upon such amendment, and the



<PAGE>
 
     affirmative vote of two-thirds of the outstanding shares of Class A
     Preferred Stock shall be necessary to the adoption thereof, in addition to
     such other vote as may be required by law.

     6.3) Preemptive Rights. Shareholders shall not have any preemptive or 
          -----------------
preferential rights for or to shares of this Corporation, whether now or 
hereafter authorized, or to any obligations convertible into shares of this 
Corporation, or to any options, warrants or other right to acquire shares of 
this Corporation, or to any subscription or right of subscription therefor, 
except such, if any, as the Board of Directors in its sole discretion may 
determine from time to time, and at such price or terms as the Board of 
Directors may fix. The Board of Directors may, at any time and from time to
time, issue and sell for such consideration as may be permitted by law and these
Articles of Incorporation, any or all of the authorized shares of the
Corporation not then issued and any and all of any stock of any class or series
that may hereafter be authorized.

     6.4) Issuance of Shares. Subject to this Article 6, the Board of Directors 
          ------------------
may issue any or all shares of the Corporation authorized by these Articles and 
not already issued, including any shares previously issued and reacquired by the
Corporation. Upon approval by the Board of Directors, shares may be issued (i) 
for any consideration determined appropriate by the Board of Directors, or (ii) 
for no consideration in order to effectuate share conversions, dividends or 
splits, including reverse splits. The Board of Directors shall determine the 
value of non-monetary consideration received for shares.

     6.5) Issuance of Rights to Acquire Shares. Subject to Section 6.4, the 
          ------------------------------------
Board of Directors may issue rights to purchase shares of the Corporation, and 
shall fix the terms, provisions and conditions of such rights to purchase, 
including the conversion basis and the price at which shares may be purchased or
subscribed for. Shares to be issuable upon the exercise of all outstanding 
rights to purchase, including such rights to be issued, must be authorized by 
these Articles and not already issued.

                                  ARTICLE 7.

                                 SHAREHOLDERS

     All shareholder actions shall require an affirmative vote of the holders of
a majority of the voting power of the shares represented and entitled to vote at
a duly held meeting, except where the law requires a vote with respect to all
outstanding shares of the Corporation, in which case the affirmative vote of a
majority of the shares entitled to vote (by class or series if more than one
class or series of shares is outstanding and entitled to vote separately as a
class or series on such matter) shall be sufficient to authorize the action.

                                  ARTICLE 8. 

                             NON-CUMULATIVE VOTING

     Unless otherwise provided in these Articles or in a Certificate of 
Designation, cumulative voting for directors shall not be permitted.




<PAGE>
 
                                  ARTICLE 9.

                                  DIRECTORS

     9.1)  Power; Voting.  The Board of Directors shall have the power and 
           -------------
authority to take any action required or permitted by law or by these Articles. 
The Board of Directors shall take action by the affirmative vote of a majority 
of directors present at a duly held meeting, except where law requires the 
affirmative vote of a larger proportion or number.

     9.2)  Written Action.  Any action required or permitted to be taken at a 
           --------------
board meeting may be taken by written action signed by a majority of directors. 
If the action must also be approved by the shareholders, then the action must be
taken by written action of all the directors.

     9.3)  Indemnification.  A director of the Corporation shall not be 
           ---------------
personally liable to the Corporation or its shareholders for monetary damages 
for breach of fiduciary duty as a director, except for (i) liability based on a 
breach of the duty of loyalty to the Corporation or the shareholders (ii) 
liability for acts or omissions not in good faith or that involve intentional 
misconduct or a knowing violation of law; (iii) liability under Minnesota 
Statutes Section 302A.559 or 80A.23; or (iv) liability for any transaction from 
which the director derived an improper personal benefit. If Chapter 302A, the 
Minnesota Business Corporation Act, is hereafter amended to authorize the 
further elimination or limitation of the liability of directors, then the 
liability of a director of the Corporation, in addition to the limitation on 
personal liability provided herein, shall be limited to the fullest extent 
permitted by the amended Chapter 302A, the Minnesota Business Corporation Act. 
Any repeal or modification of this Section 9.3 by the shareholders of the 
Corporation shall be prospective only, and shall not adversely affect any 
limitation on the personal liability of a director of the Corporation at the 
time of such repeal or modification.


                                  ARTICLE 10.

                                    BYLAWS

     The Board of Directors may adopt bylaws which may contain any provision 
relating to the management of the business or the regulation of the affairs of 
the Corporation not inconsistent with law or these Articles of Incorporation. 
The power to adopt, amend or repeal the bylaws shall be vested in the Board of 
Directors.

Re:  Registration Statement on Form S-4
  (File No. 333-53841)
  ---------------------------------

Ladies and Gentlemen:

We are special counsel to WAM!NET Inc., a Minnesota corporation (the "Company"),
and have acted as such in connection with various legal matters relating to the
filing of a Registration Statement on Form S-4 (File No. 333-53841) (the
"Registration Statement") under the Securities Act of 1933, as amended, relating
to the offer to exchange up to $208,530,000 in aggregate principal amount at
maturity of 13-1/4% Senior Discount Notes due 2005, Series B (the "Exchange
Notes"), for outstanding 13-1/4% Senior Discount Notes due 2005, Series A, that
were issued and sold in a transaction exempt from registration under the
Securities Act of 1933, as amended (the "Original Notes"). The Original Notes
were issued under, and the Exchange Notes are to be issued under, the Indenture,
dated as of March 5, 1998, between the Company and First Trust National
Association, as trustee (the "Trustee"). The exchange will be made pursuant to
an exchange offer (the "Exchange Offer") contemplated by the Registration
Statement.

In so acting, we have examined copies of such records of the Company and such
other certificates and documents as we have deemed relevant and necessary for
the opinions hereinafter set forth.  In such examination, we have assumed the
genuineness of all signatures, and the authenticity of all documents submitted
to us as originals and the conformity to authentic originals of all documents
submitted to us as certified or reproduced copies.  We have also assumed the
legal capacity of all persons executing such documents and the truth and
correctness of any representations or warranties therein contained.  As to
various questions of fact material to such opinions, we have relied upon
certificates of officers of the Company and of public officials.

Based upon the foregoing, we are of the opinion that:

1.   The Company is duly formed and validly existing under the laws of the State
     of Minnesota.

Re:  Registration Statement on Form S-4
     (File No. 333-53811)

Ladies and Gentlemen:

We have acted as special counsel to WAM!NET Inc., a Minnesota corporation (the
"Company"), in connection with the filing of a Registration Statement on Form
S-4 (File No. 333-53811) (the "Registration Statement") under the Securities Act
of 1933, as amended (the "Securities Act"), relating to the Company's offer to
exchange up to $208,530,000 in aggregate principal amount at maturity of 13 1/4%
Senior Discount Notes due 2005, Series B (the "Exchange Notes"), for outstanding
13 1/4% Senior Discount Notes due 2005, Series A (the "Original Notes"),
originally issued by the Company in reliance upon exemptions from registration
under the Securities Act. In that connection, we have prepared the section
entitled "Certain Federal Income Tax Consequences--The Exchange Offer" contained
in the Registration Statement, which section constitutes our opinion as counsel
regarding the expected U.S. federal income tax consequences of the Exchange
Offer.

Our opinion is based on the provisions of the Internal Revenue Code of 1986, as
amended, regulations under such Code, judicial authority and current
administrative rulings and practice, all as of the date of this letter, all of
which may change at any time, possibly with retroactive effect. As stated in the
above-referenced section of the Registration Statement, it is our opinion that
the exchange of Original Notes for Exchange Notes by holders will not be a
taxable exchange for federal income tax purposes, and holders should not
recognize any taxable gain or loss or any interest income as a result of such
exchange.

We hereby consent to the use of this opinion as Exhibit 8 to the Registration
Statement and related Prospectus filed with the

          Re:  WAM!NET - WorldCom
               ------------------

Dear Bill:

          As you are aware, in connection with WAM!NET Inc.'s ("WAM!NET")
proposed Rule 144A High Yield Offering ("Offering"), Merrill Lynch & Co. (one of
the initial purchasers and managing underwriter) has requested that certain of
the existing indebtedness of WAM!NET to WorldCom Inc. ("WorldCom") be modified
to explicitly provide that such indebtedness is subordinate to the indebtedness
represented by the notes in the Offering ("Notes").  This letter is intended to
memorialize the agreement of WorldCom and WAM!NET with respect to such
modification.

          In this regard, reference is hereby made to WAM!NET's (i) 10%
Convertible Subordinated Note, due September 30, 1999 ("10% Subordinated Note"),
(ii) 7% Subordinated Note, due December 31, 2003 ("7% Subordinated Note"), and
(iii) 100,000 shares of Series A Preferred Stock ("Preferred Stock"), all of
which are held by WorldCom (the 10% Subordinated Note, 7% Subordinated Note and
the Preferred Stock, collectively, are referred to herein as the "Subordinated
Securities").  The parties desire to modify the terms of the Subordinated
Securities as follows:

          1.   All payment obligations of WAM!NET in respect of the Subordinated
Securities shall be subordinate to the prior payment in full of the Notes to the
extent provided herein;
<PAGE>
 
K. William Grothe, Jr. 
February 11, 1998     
Page 2                  


          2.   No payment of principal (or premium on) or interest on, or 
dividend, distribution or other payment, in respect of such Subordinated
Securities shall be made prior to the date that is 180 days following the stated
maturity of the principal of the Notes, except that prior to such time the
Subordinated Securities may be redeemed or retired by the Issuer (or payment of
interest or dividends may be made) with, or converted into capital stock of
WAM!NET or options, warrants or other rights to purchase any such capital stock;

          3.    The payment of the principal of and interest on the 10% 
Subordinated Note and the 7% Subordinated Note may be accelerated only in the
event of the acceleration of the payment of the principal amount of the Notes
following an event of default with respect to the Notes; provided that (i) any
payment in respect of such Subordinated Securities following the acceleration
thereof shall be subordinated to the prior payment in full of all amounts due in
respect of the Notes, and (ii) in the event of the recission of any such
acceleration of the Notes, the acceleration of such Subordinated Securities
shall be deemed rescinded upon notice to such effect to the holder of the
Subordinated Securities.

          It is the understanding of the parties that WorldCom shall have the
option to convert (a) the interest due on the 10% Subordinated Note and deferred
pursuant to paragraph 2 above, and (b) the interest accrued (at a rate of 7% per
annum) on the outstanding principal amount of the 7% Subordinated Note from
December 31, 2003 through the date such amount is paid pursuant to paragraph 2
into shares of common stock, par value $.01, of WAM!NET, at the price per share
then existing on the date of such conversion.  The price per share shall be the
average closing price per share of WAM!NET common stock as reported on NASDAQ or
any national securities exchange on which such stock trades for the ten trading
days preceding the date of conversion, if the common stock is then publicly
traded, or the fair value of such shares, as determined by mutual agreement of
the parties, if the common stock is not then publicly traded.

          The provisions included herein will be operative only in the event
that the Offering is consummated, and are expected to be incorporated into
amendments to the agreements governing the Subordinated Securities, as deemed
necessary and appropriate by the parties.

applicable, by any means deemed fair and reasonable by the Committee, which
determination shall be final and binding on all parties.

        2.10.  "ISO" shall mean any stock option granted pursuant to this Plan
as an "incentive stock option" within the meaning of Section 422 of the Code.

        2.11.  "NQO" shall mean any stock option granted pursuant to this Plan,
which is not an ISO.

        2.12.  "Option" shall mean any stock option granted pursuant to this
Plan.

        2.13.  "Optionee" shall mean any person who is the holder of an Option

Corporation.

        2.15.  "Subsidiary" shall mean any corporation which at the time

        2.16.  "Tax Date" shall mean the date on which the amount of tax to be

        3.  Shares Available Under Plan.  The number of shares which may be
            ---------------------------    
issued pursuant to Options granted under this Plan, including Options granted
pursuant to an Addendum, shall not exceed 25,000,000 shares of the Common Stock
of the Corporation; provided, however, that shares which become available as a
result of canceled, unexercised, lapsed or terminated Options granted under this
Plan shall be available for issuance pursuant to Options subsequently granted
under this Plan, and the number of shares for which Options have been granted or
are available for grant under this Plan shall be proportionately increased or
decreased in accordance with Section 8 hereof upon occurrence of any event
described therein. The shares issued upon exercise of Options granted under this
Plan may be authorized and unissued shares or shares previously acquired or to
be acquired by the Corporation.

        4.  Administration.
            -------------- 

        4.1.  The Plan will be administered by the Board of Directors or by a
Committee (the "Committee") selected by the Board and consisting of at least
three members, none of whom for at least one year prior to service on the
Committee has been eligible to receive any Option under the Plan, or under any
other benefit plan of the Corporation or any of its affiliates entitling the
participants therein to acquire stock or stock options of the Corporation or any
of its Subsidiaries. The Board or such Committee are hereinafter described as
the Committee.

                                       2.

                                                                    WAM!NET Inc.
                                                 1998 Combined Stock option Plan

        4.2.  The Committee will have plenary authority, subject to provisions
of the Plan, to determine when and to whom Options will be granted, the term of
each Option, the number of shares covered by it, the participation by the
Optionee in other plans, and any other terms or conditions of each Option. The
Committee shall determine with respect to each grant of an Option whether a
participant shall receive an ISO or an NQO, or an Option pursuant to the
provisions of an Addendum. The number of shares, the term and the other terms
and conditions of a particular kind of Option need not be the same, even as to
options granted at the same time. The Committee's recommendations regarding
option grants and terms and conditions thereof will be conclusive.

        4.3.  The Committee will have the sole responsibility for construing and
interpreting the Plan, for establishing and amending any rules and regulations
as it deems necessary or desirable for the proper administration of the Plan,
and for resolving all questions arising under the Plan.  Any decision or action
taken by the Committee arising out of or about the construction, administration,
interpretation and effect of the Plan and of its rules and regulations will, to
the extent permitted by law, be within its absolute discretion, except as
otherwise specifically provided herein, and will be conclusive and binding on
all Optionees, all successors, and any other person, whether that person is
claiming under or through any Optionee or otherwise.
        
        4.4.  The Committee will designate one of its members as chairman. It
will hold its meetings at the times and places as it may determine. A majority
of its members will constitute a quorum, and all determinations of the Committee
will be made by a majority of its members. Any determination reduced to writing
and signed by all members will be fully as effective as if it had been made by a
majority vote at a meeting duly called and held. The Committee may appoint a
secretary, who need not be a member of the Committee, and may make such rules
and regulations for the conduct of its business as it may deem advisable.

        4.5.  No member of the Committee will be liable, in the absence of bad
faith, for any act or omission with respect to his services on the Committee.
Service on the Committee will constitute service as a member of the Board, so
that the members of the Committee will be entitled to indemnification and
reimbursement as Board members pursuant to the Corporation's Bylaws.

        4.6.  The Committee will regularly inform the Board as to its actions
with respect to all Options granted under the Plan and the terms and conditions
and any such Options in a manner, at any times, and in any form as the Board may
reasonably request.

        5.  Participants.
            ------------ 

        5.1.  Participation in this Plan shall be limited to employees of the
Corporation or of a Subsidiary and to Non-Employee Directors and Non-Employee
Consultants.  Non-Employee Directors and Non-Employee Consultants shall
participate under this Plan only as specified in Section 14 hereof.

                                       3.

                                                                    WAM!NET Inc.
                                                 1998 Combined Stock option Plan

        5.2.  Without amending the Plan, the Committee may grant Options to
employees of the Corporation or of any Subsidiary who are foreign nationals on
such terms and conditions different from those specified in this Plan as may in
the judgment of the Committee be necessary or desirable to foster and promote
achievement of the purposes of the Plan, and, in furtherance of such purposes
the Committee may make such Addenda, modification, amendments, procedures,
subplans and the like as may be necessary or advisable to comply with provisions
of laws in other countries in which the Corporation or any Subsidiary operates
or has employees.

        5.3.  Subject to other provisions of this Plan, Options may be granted
to the same participants on more than one occasion.

        5.4.  Except with respect to Options granted to Non-Employee Directors
or Non-Employee Consultants under Section 15, the Committee's determination
under the Plan including, without limitation, determination of the persons to
receive Options, the form, amount and type of such Options, and the terms and
provisions of Options need not be uniform and may be made selectively among
otherwise eligible participants, whether or not the participants are similarly
situated.

        6.  Terms and Conditions.
            -------------------- 

        6.1.  Each Option granted under the Plan shall be evidenced by a written
agreement, which shall be subject to the provisions of this Plan and to such
other terms and conditions as the Corporation may deem appropriate.

        6.2.  Each Option agreement shall specify the period for which the
Option thereunder is granted which in no event shall exceed ten years from the
date of the grant for any Option designated by the Committee as an ISO or ten
years and one day from the date of grant for any Option and shall provide that
the Option shall expire at the end of such period.

        6.3.  The exercise price per share shall be determined by the Committee
at the time any Option is granted and, if the Option is an ISO, shall be no less
than one hundred percent (100%) of Fair Market Value of the Common Stock of the
Corporation on the date the Option is granted, as determined by the Committee.

        6.4.  The aggregate Fair Market Value (determined as of the time the
Option is granted) of the Common Stock with respect to which an ISO under this
Plan or any other plan of the Corporation or its Subsidiaries is exercisable for
the first time by an Optionee during any calendar year shall not exceed
$100,000.

        6.5.  An Option shall be exercisable at such time or times, and with
respect to such minimum number of shares, as may be determined by the
Corporation at the time of the grant. The Option agreement may require, if so
determined by the Corporation, that no part of the Option may be exercised until
the Optionee shall have remained in the employ of the Corporation or of a
Subsidiary for such period after the date of the Option as the Corporation may
specify.

                                                 1998 Combined Stock option Plan

        6.6.  The Corporation may prescribe the form of legend which shall be
affixed to the stock certificate representing shares to be issued and the shares
shall be subject to the provisions of any repurchase agreement or other
agreement restricting the sale or transfer thereof. Such agreements or
restrictions shall be noted on the certificate representing the shares to be
issued.

        6.7.  Each Incentive Stock Option granted hereunder shall not be
transferable by the Optionee other than by will or by the laws of descent and
distribution, and shall be, during the Optionee's lifetime, exercisable only by
the Optionee or Optionee's guardian or legal representative. Each Non-Qualified
Stock Option granted hereunder may be transferred by the Optionee for estate
planning purposes subject to prior or other written approval by the Committee in
its sole discretion or pursuant to any policy and requirements concerning such
transfers then in effect as the Committee may in its discretion establish, amend
or revoke from time to time; by will or the laws of descent and distribution; or
pursuant to a qualified domestic relations order as defined in Section 414 of
the Code or Section 206 of the Employee Retirement Income Security Act, or rules
thereunder. Except as permitted by the preceding sentences, each Option granted
under the Plan and the rights and privileges thereby conferred shall not be
transferred, assigned or pledged in any way (whether by operation of law or
otherwise), and shall not be subject to execution, attachment or similar
process. Any attempt to so transfer, assign, pledge or otherwise dispose of an
Option, or of any right or privilege conferred thereby, contrary to the
provisions of the Option or the Plan, or any levy of any attachment or similar
process upon such rights and privileges, shall be void and unenforceable against
the Corporation.

        7.  Exercise of Option.
            ------------------ 

        7.1.  Each exercise of an Option granted hereunder, whether in whole or
in part, shall be by written notice thereof, delivered to the Secretary of the
Corporation (or such other person as may be designated). The notice shall state
the number of shares with respect to which the Options are being exercised and
shall be accompanied by payment in full for the number of shares so designated.
Shares shall be registered in the name of the Optionee unless the Optionee
otherwise directs in his or her notice of election.

        7.2.  Payment shall be made to the Corporation either (i) in cash,
including certified check, bank draft or money order, (ii) at the discretion of
the Corporation, by delivering Common Stock of the Corporation already owned by
the participant, (iii) at the discretion of the Corporation, by delivering a
promissory note, containing such terms and conditions acceptable to the
Corporation, for all or a portion of the purchase price of the shares so
purchased, or a combination of (i), (ii) and (iii). With respect to (ii), the
Fair Market Value of stock so delivered shall be determined as of the date
immediately preceding the date of exercise.

        7.3.  Upon notification of the amount due and prior to, or concurrently
with, the delivery to the Optionee of a certificate representing any shares
purchased pursuant to the exercise of an Option, the Optionee shall promptly pay
to the Corporation any amount necessary to satisfy applicable federal, state or
local withholding tax requirements.

                                                 1998 Combined Stock option Plan

        8.  Adjustment of Option Stock.  In case the shares issuable upon
            --------------------------        
exercise of any Option granted under the Plan at any time outstanding shall be
subdivided into a greater or combined into a lesser number of shares (whether
with or without par value), the number of shares purchasable upon exercise of
such Option immediately prior thereto shall be adjusted so that the Optionee
shall be entitled to receive a number of shares which he or she would have owned
or have been entitled to receive after the happening of such event had such
Option been exercised immediately prior to the happening of such subdivision or
combination or any record date with respect thereto. An adjustment made pursuant
to this paragraph shall become effective immediately after the effective date of
such subdivision or combination retroactive to the record date, if any, for such
subdivision or combination. The option price (as such amount may have
theretofore been adjusted pursuant to the provisions hereof) shall be adjusted
by multiplying the option price immediately prior to the adjustment of the
number of shares purchasable under the Option by a fraction, of which the
numerator shall be the number of shares purchasable upon the exercise of the
Option immediately prior to such adjustment, and of which the denominator shall
be the number of shares so purchasable immediately thereafter. Substituted
shares of stock shall be deemed shares under Section 3 of the Plan.

        9.  Change in Control.
            ----------------- 

        9.1.  For purposes of this Section 9, a "Change in Control" of the
Corporation will mean (i) the sale, lease, exchange or other transfer of
substantially all of the assets of the Corporation (in one transaction or in a
series of related transactions) to a person or entity that is not controlled,
directly or indirectly, by the Corporation, (ii) a merger or consolidation to
which the Corporation is a party if the stockholders of the Corporation
immediately prior to effective date of such merger or consolidation do not have
"beneficial ownership" (as defined in Rule 13d-3 under the Securities Exchange
Act of 1934, as amended) immediately following the effective date of such merger
or consolidation of more than 80% of the combined voting power of the surviving
corporation's outstanding securities ordinarily having the right to vote at
elections of directors, or (iii) a change in control of the Corporation of a
nature that would be required to be reported pursuant to Section 13 or 15(d) of
the Securities Exchange Act of 1934, as amended, whether or not the Corporation
is then subject to such reporting requirements, including, without limitation,
such time as (1) any person becomes, after the effective date of the Plan, the
"beneficial owner" (as defined in Rule 13d-3 under the Securities Exchange Act
of 1934, as amended), directly or indirectly, of 40% or more of the combined
voting power of the Corporation's outstanding securities ordinarily having the
right to vote at elections of directors, or (2) individuals who constitute the
Board of Directors on the effective date of the Plan cease for any reason to
constitute at least a majority of the Board, provided that any person becoming a
director subsequent to the effective date of the Plan whose election, or
nomination for election by the Corporation's stockholders, was approved by a
vote of at least a majority of the directors comprising the Board on the
effective date of the Plan will, for purposes of this Section 9.1, be considered
as though such persons were a member of the Board of Directors on the effective
date of the Plan.

        9.2.  Without limiting the authority of the Committee under Section 4 of
the Plan, if a Change in Control of the Corporation occurs, then, if approved by
the Committee in its sole 

                                       6.

                                                                    WAM!NET Inc.
                                                 1998 Combined Stock option Plan

discretion either in an agreement evidencing an Option grant at the time of
grant or at any time after the grant of an Option, all Options will become
immediately exercisable in full and will remain exercisable in accordance with
the terms of the Plan; provided, however, that a recipient of Incentive Stock
Options may elect that such acceleration of vesting not apply with respect to
some or all of the Incentive Stock Options granted to him by so notifying the
Committee in writing within three (3) business days of being notified of the
Committee's actions pursuant to this Section 9.

        9.3.  If a Change in Control of the Corporation occurs, then the
Committee in its sole discretion either in an agreement evidencing an Option
grant at the time of grant or at any time after the grant of an Option, and
without the consent of any Option recipient effected thereby, may determine that
some or all recipients holding outstanding Options will receive, with respect to
and in lieu of some or all of the shares of Option Stock, as of the effective
date of any such Change in Control of the Corporation, cash in an amount equal
to the excess of the Fair Market Value of such shares either immediately prior
to the effective date of such Change in Control of the Corporation or, if
greater, determined on the basis of the amount paid as consideration by the
other party(ies) to the Change in Control transaction over the exercise price
per share of such Options.

        9.4.  Notwithstanding anything in Section 9.2 or 9.3 of the Plan to the
contrary, if the Corporation is then subject to the provisions of Section 280G
of the Code, and if the acceleration of the vesting of an Option as provided in
Section 9.2 or the payment of cash in exchange for all or part of an Option as
provided in Section 9.3 (which acceleration or payment could be deemed a
"payment" within the meaning of Section 28OG(b)(2) of the Code), together with
any other payments which such recipient has the right to receive from the
Corporation or any corporation that is a member of an "affiliated group" (as
defined in Section 1504(a) of the Code without regard to Section 1504(b) of the
Code) of which the Corporation is a member, would constitute a "parachute
payment" (as defined in Section 28OG(b)(2) of the Code), then the payments to
such recipient pursuant to Section 9.2 or 9.3 will be reduced to the largest
amount as will result in no portion of such payments being subject to the excise
tax imposed by Section 4999 of the Code; provided, however, that if such
recipient is subject to a separate agreement with the Corporation or a
Subsidiary which specifically provides that payments attributable to one or more
forms of employee stock incentives or to payments made in lieu of employee stock
incentives will not reduce any other payments under such agreement, even if it
would constitute an excess parachute payment, then the limitations of this
Section 9.4 will, to that extent, not apply.

        10.  Assignments.  Other than as provided in Section 6.7, any Option
             -----------
granted under this Plan shall be exercisable only by the Optionee to whom
granted during his or her lifetime and shall not be assignable or transferable
otherwise than by will or by the laws of descent and distribution.

        11.  Severance; Death; Disability.  An Option shall terminate, and no
             ----------------------------    
rights thereunder may be exercised, if the person to whom it is granted ceases
to be employed by the Corporation or by a Subsidiary except that:

                                                                    WAM!NET Inc.
                                                 1998 Combined Stock option Plan

        11.1.  If the employment of the Optionee is terminated by any reason
other than his or her death or disability, the Optionee may at any time within
not more than three months after termination of his or her employment, exercise
his or her Option rights but only to the extent they were exercisable by the
Optionee on the date of termination of his or her employment; provided, however,
that if the employment is terminated as a result of the Optionee's deliberate,
willful or gross misconduct as determined by the Committee, all rights under the
Option shall terminate and expire upon such termination.

        11.2.  If the Optionee dies while in the employ of the Corporation or a
Subsidiary, or within not more than three months after termination of his or her
employment, the Optionee's rights under the Option may be exercised at any time
within one year following such death by his or her personal representative or by
the person or persons to whom such rights under the Option shall pass by will or
by the laws of descent and distribution, but only to the extent they were
exercisable by the Optionee on the date of death.

        11.3.  If the employment of the Optionee is terminated because of
permanent disability, the Optionee, or his or her legal representative, may at
any time within not more than one year after termination of his or her
employment, exercise his or her Option rights but only to the extent they were
exercisable by the Optionee on the date of termination of his or her employment.

        11.4.  The same exercise periods as provided in Sections 11.1, 11.2 and
11.3 shall also apply with respect to a tranferee of an Option pursuant to
Section 6.7, including the extension of the exercise period under Section 11.2
upon the death of the tranferee.

        11.5.  Any provision of Sections 11.1, 11.2 and 11.3 to the contrary
notwithstanding, no Option or any right claimed thereby, therein or thereunder
shall be exercisable by anyone after the expiration of the term of the Option.

        11.6.  Transfers of employment between the Corporation and a Subsidiary,
or between Subsidiaries, will not constitute termination of employment for
purposes of any Option granted under this Plan. The Committee may specify in the
terms and conditions of an Option whether any authorized leave of absence or
absence for military or government service or for any other reasons will
constitute a termination of employment for purposes of the Option and the Plan.

        12.  Rights of Participants.  Neither the participant nor the personal
             ----------------------                                           
representatives, heirs, or legatees of such participant shall be or have any of
the rights or privileges of a shareholder of the Corporation in respect of any
of the shares issuable upon the exercise of an Option granted under this Plan
unless and until certificates representing such shares shall have been issued
and delivered to the participant or to such personal representatives, heirs or
legatees.

        13.  Securities Registration.  If any law or regulation of the 
             -----------------------      
Securities and Exchange Commission or of any other body having jurisdiction
shall require the Corporation or the participant to take any action in
connection with the exercise of an Option, then notwithstanding any contrary
provision of an Option agreement or this Plan, the date for exercise of such
Option 

                                       8.

                                                                    WAM!NET Inc.
                                                 1998 Combined Stock option Plan

and the delivery of the shares purchased thereunder shall be deferred until the
completion of the necessary action. In the event that the Corporation shall deem
it necessary, the Corporation may condition the grant or exercise of an Option
granted under this Plan upon the receipt of a satisfactory certificate that the
Optionee is acquiring the Option or the shares obtained by exercise of the
Option for investment purposes and not with the view or intent to resell or
otherwise distribute such Option or shares. In such event, the stock certificate
evidencing such shares shall bear a legend referring to applicable laws
restricting transfer of such shares. In the event that the Corporation shall
deem it necessary to register under the Securities Act of 1933, as amended, or
any other applicable statute, any Options or any shares with respect to which an
Option shall have been granted or exercised, then the participant shall
cooperate with the Corporation and take such action as is necessary to permit
registration or qualification of such Options or shares.

        14.  Duration and Amendment.
             ---------------------- 

        14.1.  There is no express limitation upon the duration of the Plan,
except for the requirement of the Code that all ISO's must be granted within ten
years from the date the Plan is approved by the shareholders.

        14.2.  The Board may terminate or may amend the Plan at any time;
provided, however, that the Board may not, without approval of the shareholders
of the Corporation, (i) increase the maximum number of shares as to which
Options may be granted under the Plan, (ii) permit the granting of ISO's at less
than 100% of Fair Market Value at time of grant, (iii) change the class of
employees eligible to receive Options under the Plan, or (iv) permit Directors
to receive options under the Plan other than pursuant to Section 15 hereof; and,
provided further, that the Board may not amend the Plan more than once every six
months, other than to comport with changes in the Code, the Employee Retirement
Income Security Act, or rules thereunder.

        15.  Granting of Options to Non-Employee Directors and Non-Employee 
             --------------------------------------------------------------
Consultants.
- ------------ 

        15.1.  Non-Employee Directors and Non-Employee Consultants shall be
entitled to receive such Options under this Plan as may be granted to them from
time to time.

        15.2.  All Options granted to Non-Employee Directors and Non-Employee
Consultants shall be designated as NQOs, shall be evidenced by a written option
agreement signed by the Corporation and the Non-Employee Director or Non-
Employee Consultant, and shall be subject to the same terms and provisions as
are then in effect with respect to granting of NQOs to salaried officers and key
employees of the Corporation, except that the Option shall be exercisable as to
all or any part of the shares subject to the Option from the date the Option is
granted, and shall expire on the earliest of (i) twelve months after the
Optionee ceases to be a Non-Employee Director or a Non-Employee Consultant
(except by death), (ii) one year after the death of the optionee, or (iii) seven
years after the date of grant.  Subject to the foregoing, all provisions of this
Plan not inconsistent with the foregoing shall apply to Options granted to Non-
Employee Directors, except that Non-Employee Directors shall always have the
right to deliver stock in exercise of options as provided in Section 7.2.

satisfied PROVIDED THAT:

        3.1)  Any condition that relates to performance howsoever measured shall
be objective and:

        (a)  if there is an event or change in circumstances which causes any
        such condition (whether or not specified in these Rules) to become
        inappropriate the Committee may, acting fairly and reasonably, alter,
        add to or waive any part or all of the said condition save that the
        condition in any amended form will be a fairer measure of performance
        and will be equivalent to (and in any event no more difficult to satisfy

        addition; and

        (b)  except as otherwise determined by the Committee at the time at
        which the Option is granted, the said condition shall cease to apply in

        different conditions, to the conditions specified in the Option as it
        may decide;

provided that no such adjustment shall be made unless the Auditors (acting as
experts and not as arbitrators) shall have confirmed in writing to the Committee
that the adjustment is, in their opinion, fair and reasonable.

manner as the Committee may from time to time prescribe. In the absence of the

writing signed by the Participant, which notice shall specify the number of

remaining subject to the Option) in respect of which the Option is being
exercised and shall be accompanied both by payment in full of the aggregate
Subscription Price for the said Shares and the option certificate evidencing the
grant of the relevant Option for cancellation or amendment. The date of receipt
of such notice shall (in the absence of the Committee prescribing otherwise) be
deemed to be the date of exercise of the Option or of the relevant portion of
the Option, as the case may be.

        5.2)  Allotment/Transfer.  The Corporation shall allot to the

the Corporation issues share certificates the Corporation shall deliver to the
Participant or his nominee a definitive share certificate in respect thereof.

             the period of six months (or such longer period as may be allowed
             pursuant to the proviso to this Rule 6.5) after ceasing to be so
             employed and, subject to Rule 6.3, at the expiry of that period his
             Option, to the extent unexercised shall lapse and become of no

        Rule 6.3 must, if at all) be exercised to the extent permitted by the
        Committee within the period of six months after ceasing to be so

        7.2)  If a Change in Control of the Corporation occurs, then each
Participant shall be notified by the Committee of whether or not such Change in
Control has resulted in the requirements of paragraphs 10 to 14 inclusive of
Schedule 9 ceasing to be satisfied and may, subject to Rules 3 and 5, exercise
his Option at any time and from time to time within the period of six months
following the Change in Control notwithstanding that such exercise may occur
within three years of the date on which the Option was granted and at the end of
that period all Options, to the extent unexercised, shall lapse.

                                   ARTICLE 8.

              VARIATIONS IN THE SHARE CAPITAL OF THE CORPORATION
              --------------------------------------------------

        8.1)  Variation or Reorganization.  If at any time after the date of 
              ---------------------------      
grant of an Option and before it ceases to be exercisable there is a variation
or reorganization of the share capital of the Corporation by virtue of which
Shares are subdivided into a greater or combined into a lesser number of shares
(whether with or without par value), the number of Shares issuable upon exercise
of such Option immediately prior thereto shall be adjusted so that the
Participant shall be entitled to receive a number of Shares which he or she
would have owned or have been 

                                      A-8
<PAGE>
 
entitled to receive after the happening of such event had such Option been
exercised immediately prior to the happening of such subdivision or combination
or any record date with respect thereto. An adjustment made pursuant to this
Rule shall become effective immediately after the effective date of such
subdivision or combination retroactive to the record date, if any, for such
subdivision or combination. The Subscription Price (as such amount may have
theretofore been adjusted pursuant to the provisions hereof) shall be adjusted
by multiplying the Subscription Price immediately prior to the adjustment of the
number of Shares issuable under the Option by a fraction, of which the numerator
shall be the number of Shares issuable upon the exercise of the Option
immediately prior to such adjustment, and of which the denominator shall be the
number of Shares so issuable immediately thereafter. Substituted shares of stock
shall be deemed Shares for the purpose of this Scheme.

        8.2)  In the event of any other variation of the share capital of the
Corporation not falling within Rule 8.1, the Subscription Price and/or the
number of Shares in respect of which the Option may be exercised shall be
adjusted to such extent and in such manner as the Auditors shall in their
opinion consider and confirm in writing to the Committee to be fair and
reasonable.

        8.3)  Notwithstanding Rules 8.1 and 8.2, the aggregate Subscription
Price payable on the exercise of an Option previously granted hereunder shall
not be increased by any adjustment pursuant to Rule 8.1 or Rule 8.2 and any such
adjustments shall be subject to prior approval by the Board of Inland Revenue.

        8.4)  All Participants shall be notified in writing of any such
adjustments as soon as practicable thereafter and the Corporation shall be
entitled to call in the option certificates for the Options affected by such
adjustments for endorsement or replacement, as may appear appropriate.

                                   ARTICLE 9.

fit. Any dispute regarding the interpretation of the Scheme or the terms of any
Option shall be determined by the Committee in its discretion (after seeking
such advice as it shall consider necessary) and its decision shall be final and
binding.

        9.2)  Authorized Share Capital.  The Corporation shall at all times 
              ------------------------

outstanding Options to subscribe for Shares under the Scheme.

        9.3)  Notices.  Any notice or other communication under or in 
              -------   
connection with the Scheme may be given by personal delivery or by sending the

             (1)  the Board shall have invited every such Participant to give an
                  indication as to whether or not he approves the amendment; and

             (2)  the amendment is approved by a majority of those Participants
                  who have given such an indication;

        (b)  no amendment to the advantage of any existing or future
        Participants shall be made without the prior approval by ordinary
        resolution of the shareholders of the Company in general meeting (except
        for minor amendments to benefit the administration of the Scheme, to
        take account of a change in legislation or to obtain or maintain any
        favorable tax, exchange-control or regulatory treatment for Participants
        or for any Participating Company);

        (c)  with the exception of amendments to any conditions attached to any
        Option pursuant to Rule 3.1, no amendment made to the Scheme shall
        become effective until it has been approved by the Board of Inland
        Revenue and nothing shall be done to the Scheme which would prejudice
        the obtaining of Revenue Approval or cause it to be withdrawn.

        10.2)  Revenue Approval.  The Board may at any time by resolution and 
               ----------------

withdrawn pursuant to any statutory modification of the provisions of the Act.

               ------------                                                    
Participants shall be notified in writing as soon as practicable thereafter.

        10.4)  Termination.  The Board or the Corporation in a general meeting

of the shareholders shall be entitled by resolution to terminate the Scheme at
any time but Options previously granted shall continue to be valid and
exercisable in accordance with the provisions of the Scheme.

                             ADDITIONAL PROVISIONS
                             ---------------------

        11.1)  Conflict.  Every Option shall be subject to the condition that 
               --------   
no Shares shall be issued to a Participant following the exercise of an Option
if such issue would be contrary to any enactment or regulation for the time
being in force of the United Kingdom or of any other country having jurisdiction
in relation thereto. The Corporation shall not be bound to take any action to
obtain the consent of any governmental authority to such issue or to take any
action to ensure that any such issue shall be in accordance with any such
enactment or regulation if such action could in the opinion of the Committee be
unduly onerous.

        11.2)  Employment.  The rights and obligations of any individual under
               ----------   
the terms of his employment with any member of the Group shall not be affected

in the Scheme or any right which he may have to participate therein, and an
individual who participates therein shall waive any and all rights to
compensation or damages in consequence of the termination of his office or
employment for any reason whatsoever insofar as those rights arise or may arise
from his ceasing to have rights under or be entitled to exercise an Option as a
result of such termination.

        11.3)  Auditors.  In any matter in which they are required to act 
               --------   
hereunder the Auditors shall be deemed to be acting as experts and not as
arbitrators.

                              THE APPENDIX TO THE
                              -------------------
                       1998 SHARE OPTION SCHEME ADDENDUM
                       ---------------------------------
                                 ("THE SCHEME")

                       THE UNAPPROVED PART OF THE SCHEME
                       ---------------------------------

1.   This Appendix sets out the provisions of a sub-scheme to the Scheme, which
     sub-scheme shall be known as the "Unapproved Part."  It is intended that
     the Unapproved Part of the Scheme shall not be approved by the Inland
     Revenue.

2.   The provisions of the Unapproved Part of the Scheme shall be all the
     provisions set out in the Scheme and any Option granted under the
     Unapproved Part shall be governed in accordance with those provisions but
     with the following modifications:

        (a)  In Rule 1.1 of the Scheme a director or employee will not be
             excluded from being an "Eligible Employee" by virtue of the
             prohibition in the provisions of paragraph 8 of Schedule 9 and the
             "Shares" need not satisfy the conditions specified in paragraphs 10
             to 14 inclusive of Schedule 9.

        (b)  In Rule 1.1(y) of the Scheme, the Subscription Price shall be
             determined by the Committee using a traded market value, if any, or
             other fair market value as the Committee shall determine in its
             discretion, but in any event without the necessity to obtain the
             agreement of the Shares Valuation Division, provided that such
             value shall not be less than the nominal or par value of a Share.

        (c)  Rule 4 of the Scheme shall not apply and for the avoidance of doubt
             the Unapproved Part shall not include any restriction under
             paragraph 28 of Schedule 9 (as amended by Section 114(2) of the
             Finance Act 1996) on the number of Shares over which the Board may
             grant an Option to an Eligible Employee.

        (d)  Rule 5.4 and the proviso to Rule 6.5 of the Scheme shall not apply.

        (e)  Rule 6.1(a) of the Scheme notwithstanding, an Option may be
             exercised earlier than three years after the date on which it was
             granted if and as provided in the Option Certificate.

        (f)  In Rules 6.1(b) and 6.3 of the Scheme the period of ten years shall
             remain as stated except where Section 135 (Subsections (2) and (5))
             of the Act provide for another period, in which case such other
             period shall apply.

        (g)  Any requirement in any Rules of the Scheme relating to the approval
             of the Board of Inland Revenue shall not apply for the purposes of
             the Unapproved Part of the Scheme.

        (h)  Any Amendment made to the Scheme by virtue of any provision
             contained therein shall be deemed to have been incorporated in the
             Unapproved Part, at the date that any such amendment becomes
             effective, unless the contrary is stipulated at the time. For the
             avoidance of doubt the Board may amend this Appendix and the
             Unapproved Part without such amendment having the effect of
             amending the Scheme.
