     Verio Inc., a Delaware corporation (the "Issuer"), hereby offers, upon the
terms and conditions set forth in this Prospectus and the accompanying letter of
transmittal (the "Letter of Transmittal," which, together with this Prospectus,
constitutes the "Exchange Offers") to exchange up to (i) $100,000,000 aggregate
principal amount of its 13 1/2% Senior Notes Due 2004 (the "New 1997 Notes") for
a like aggregate principal amount of the issued and outstanding 13 1/2% Senior
Notes Due 2004 (the "Old 1997 Notes," and collectively with the New 1997 Notes,
the "1997 Notes"), of which $100,000,000 aggregate principal amount remains
outstanding following the Refinancing (as defined), and (ii) $175,000,000
aggregate principal amount of its 10 3/8% Senior Notes Due 2005 (the "New 1998
Notes") for a like aggregate principal amount of the issued and outstanding
10 3/8% Senior Notes Due 2005 (the "Old 1998 Notes," and collectively with the
New 1998 Notes, the "1998 Notes"), of which $175,000,000 aggregate principal
amount is outstanding. For purposes hereof, the New 1997 Notes and the New 1998
Notes are collectively referred to as the "New Notes," the Old 1997 Notes and
the Old 1998 Notes are collectively referred to as the "Old Notes," and the 1997
Notes and the 1998 Notes are collectively referred to as the "Notes." See "The
Exchange Offers."
    
 
   
     The Issuer will accept for exchange any and all Old Notes which are
properly tendered in the Exchange Offers and not withdrawn on or prior to 5:00
p.m., New York City time, on             , 1998, unless the Exchange Offers are
extended by the Issuer (the "Expiration Date"). Tenders of Old Notes may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration
Date. The Exchange Offers are not conditioned upon any minimum principal amount
of Old Notes being tendered for exchange. However, the Exchange Offers are
subject to certain customary conditions which may be waived by the Issuer. The
Issuer has agreed to pay the expenses of the Exchange Offers. See "The Exchange
Offers." There will be no cash proceeds to the Issuer from the Exchange Offers.
See "Use of Proceeds."
    
 
   
     Each broker-dealer that receives New Notes for its own account pursuant to
the Exchange Offers must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes. See "The Exchange
Offers -- Resales of the New Notes" and "Plan of Distribution." 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 of 1933, as amended (the "Securities Act"). This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of New Notes received in exchange
for Old Notes where such Old Notes were acquired by such broker-dealer as a
result of market-making activities or other trading activities. The Issuer has
agreed that, starting on the Expiration Date and ending on the close of business
on the 180th day following the Expiration Date, it will make this Prospectus
available to any broker-dealer for use in connection with any such resale. See
"Plan of Distribution."
    
 
   
     The Old 1997 Notes were originally issued and sold (the "Initial 1997 Notes
Offering") to Merrill Lynch, Pierce, Fenner & Smith Incorporated and Lazard
Freres & Co. LLC. (the "Initial 1997 Notes Purchasers") pursuant to a Purchase
Agreement, dated June 17, 1997 (the "1997 Notes Purchase Agreement"), among the
Issuer and the Initial 1997 Notes Purchasers, pursuant to which the Issuer sold
150,000 Units consisting of the Old 1997 Notes and Warrants to purchase
2,112,480 shares of Common Stock. The Initial 1997 Notes Purchasers subsequently
resold the Old 1997 Notes in reliance on Rule 144A of the
                                                        (Continued on next page)
    
 
     This Prospectus and the Letter of Transmittal are first being mailed to
holders of the Old Notes on               , 1998.
 
   
     SEE "RISK FACTORS" BEGINNING ON PAGE 13 FOR A DISCUSSION OF CERTAIN FACTORS
THAT SHOULD BE CONSIDERED BY HOLDERS IN EVALUATING THE EXCHANGE OFFERS.
    
 
  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
   AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
                               CRIMINAL OFFENSE.

Securities Act. The Issuer and the Initial 1997 Notes Purchasers also entered
into a 1997 Notes Registration Rights Agreement, dated June 17, 1997 (the "1997
Notes Registration Rights Agreement"), pursuant to which the Issuer granted
certain registration rights for the benefit of the holders of the Old 1997
Notes. The New 1997 Notes are being offered for exchange in order to satisfy
certain obligations of the Issuer under such 1997 Registration Rights Agreement.
The New 1997 Notes will be obligations of the Issuer evidencing the same
indebtedness as the Old 1997 Notes and will be issued under and entitled to the
benefits of the Indenture, dated as of June 24, 1997 (the "1997 Indenture"),
between the Issuer and First Trust National Association, as trustee (in such
capacity, the "Trustee"). The form and terms of the New 1997 Notes are identical
in all material respects to the Old 1997 Notes, except that the offer and
exchange of the New 1997 Notes will be registered under the Securities Act, and
therefore such New 1997 Notes will not be subject to certain transfer
restrictions and registration rights provisions applicable to the Old 1997
Notes. See "The Exchange Offers -- Purpose and Effect."
    
 
   
     The Old 1998 Notes were originally issued and sold (the "Initial 1998 Notes
Offering") to Salomon Brothers Inc, Lazard Freres & Co. LLC, Chase Securities
Inc. and BancBoston Securities Inc. (the "Initial 1998 Notes Purchasers" and,
together with the Initial 1997 Notes Purchasers, the "Initial Purchasers")
pursuant to a Purchase Agreement, dated March 19, 1998 (the "1998 Notes Purchase
Agreement"), among the Issuer and the Initial 1998 Notes Purchasers, pursuant to
which the Issuer sold the Old 1998 Notes. The Initial 1998 Notes Purchasers
subsequently resold the Old 1998 Notes in reliance on Rule 144A of the
Securities Act. The Issuer and the Initial 1998 Notes Purchasers also entered
into a 1998 Notes Registration Rights Agreement, dated March 19, 1998 (the "1998
Notes Registration Rights Agreement"), pursuant to which the Issuer granted
certain registration rights for the benefit of the holders of the Old 1998
Notes. The New 1998 Notes are being offered for exchange in order to satisfy
certain obligations of the Issuer under such 1998 Registration Rights Agreement.
The New 1998 Notes will be obligations of the Issuer evidencing the same
indebtedness as the Old 1998 Notes and will be issued under and entitled to the
benefits of the Indenture, dated as of March 25, 1998 (the "1998 Indenture"),
between the Issuer and the Trustee. The form and terms of the New 1998 Notes are
identical in all material respects to the Old 1998 Notes, except that the offer
and exchange of the New 1998 Notes will be registered under the Securities Act,
and therefore such New 1998 Notes will not be subject to certain transfer
restrictions and registration rights provisions applicable to the Old 1998
Notes. See "The Exchange Offers -- Purpose and Effect."
    
 
   
     The New 1997 Notes will mature on June 15, 2004. Interest on the New 1997
Notes will be payable semi-annually on June 15 and December 15 of each year
commencing June 15, 1998. Holders whose Old 1997 Notes are accepted for exchange
will have the right to receive interest accrued thereon from the date of
original issuance to the date of issuance of the New 1997 Notes, such interest
to be payable with the first interest payment on the New 1997 Notes. Interest on
the Old 1997 Notes accepted for exchange will cease to accrue on the day prior
to the issuance of the New 1997 Notes. See "Description of the 1997 Notes." The
New 1997 Notes will be redeemable at the option of the Issuer, in whole or in
part, at any time on or after June 15, 2002, at the redemption prices set forth
herein, plus accrued and unpaid interest, if any, to the date of redemption. See
"Description of the 1997 Notes -- Redemption."
    
 
   
     The New 1998 Notes will mature on April 1, 2005. Interest on the New 1998
Notes will be payable semi-annually on April 1 and October 1 of each year
commencing October 1, 1998. Holders whose Old 1998 Notes are accepted for
exchange will have the right to receive interest accrued thereon from the date
of original issuance to the date of issuance of the New 1998 Notes, such
interest to be payable with the first interest payment on the New 1998 Notes.
Interest on the Old 1998 Notes accepted for exchange will cease to accrue on the
day prior to the issuance of the New 1998 Notes. See "Description of the 1998
Notes." The New 1998 Notes will be redeemable at the option of the Issuer, in
whole or in part, at any time on or after April 1, 2002, at the redemption
prices set forth herein, plus accrued and unpaid interest, if any, to the date
of redemption. See "Description of the 1998 Notes -- Redemption."
    
 
   
     The Notes are senior unsecured obligations of the Issuer, ranking pari
passu in right of payment with all existing and future unsecured and
unsubordinated indebtedness of the Issuer and senior in right of payment to all
existing and future subordinated indebtedness of the Issuer. The Notes are
effectively subordinated to all indebtedness of the Issuer to the extent of the
value of the assets securing such indebtedness and to all indebtedness of
subsidiaries of the Issuer. As of December 31, 1997, on a pro forma basis after
giving effect to the Initial 1998 Notes Offering, there would have been
approximately $9.6 million of secured long-term indebtedness outstanding to
which holders of Notes would have been effectively subordinated in right of
    
 
                                       ii
<PAGE>   4
 
   
payment and approximately $7.0 million of subsidiary indebtedness to which
holders of Notes would have been structurally subordinated.
    
 
   
     The Issuer is making the Exchange Offers in reliance on the position of the
Staff of the Securities and Exchange Commission (the "Commission") as set forth
in certain interpretive letters issued to third parties in other transactions.
However, the Issuer has not sought its own interpretive letter, and there can be
no assurance that the Commission would make a similar determination with respect
to the Exchange Offers. Based on the Commission's interpretations, the Issuer
believes that New Notes issued pursuant to the Exchange Offers to any holder of
Old Notes in exchange for Old Notes may be offered for resale, resold and
otherwise transferred by such holder (other than a broker-dealer who purchased
Old Notes directly from the Issuer for resale pursuant to Rule 144A under the
Securities Act or any other available exemption under the Securities Act)
without further compliance with the registration and prospectus delivery
provisions of the Securities Act, provided that such holder is not an
"affiliate" of the Issuer (within the meaning of Rule 405 under the Securities
Act), is acquiring the New Notes in the ordinary course of business and is not
participating, and has no arrangement or understanding with any person to
participate, in the distribution of the New Notes. Holders wishing to accept the
Exchange Offers must represent to the Issuer that such conditions have been met.
In addition, if such holder is not a broker-dealer, it must represent that it is
not engaged in, and does not intend to engage in, a distribution of the New
Notes. Each broker-dealer that receives New Notes for its own account in
exchange for Old Notes, where such Old Notes were acquired by such broker-dealer
as a result of market-making activities or other trading activities, must
acknowledge that it will deliver a prospectus in connection with any resale of
such New Notes. See "The Exchange Offers -- Resales of the New Notes" and "Plan
of Distribution." This Prospectus, as it may be amended or supplemented from
time to time, may be used by a broker-dealer in connection with resales of New
Notes received in exchange for Old Notes where such Old Notes were acquired by
such broker-dealer as a result of market-making or other trading activities.
    
 
     There has previously been only a limited secondary market, and no public
market, for the Old Notes. The Old Notes are eligible for trading in the Private
Offering, Resales and Trading through Automatic Linkages ("PORTAL") market. In
addition, the Initial Purchasers have advised the Issuer that they currently
intend to make a market in the New Notes; however, the Initial Purchasers are
not obligated to do so and any market making activities may be discontinued by
the Initial Purchasers at any time. Therefore, there can be no assurance that an
active market for the New Notes will develop. If such a trading market develops
for the New Notes, future trading prices will depend on many factors, including,
among other things, prevailing interest rates, the Issuer's results of
operations and the market for similar securities. Depending on such factors, the
New Notes may trade at a discount from their face value. See "Risk
Factors -- Lack of Public Market."
 
   
     Any Old Notes not tendered and accepted in the Exchange Offers will remain
outstanding and will be entitled to all the same rights and will be subject to
the same limitations applicable thereto under the 1997 Indenture or 1998
Indenture, as applicable (except for those rights which terminate upon
consummation of the Exchange Offers). Following consummation of the Exchange
Offers, the holders of the Old Notes will continue to be subject to the existing
restrictions upon transfer thereof and the Issuer will have no further
obligation to such holders (other than to the Initial Purchasers under certain
limited circumstances) to provide for registration under the Securities Act of
the Old Notes held by them. To the extent that Old Notes are tendered and
accepted in the Exchange Offers, a holder's ability to sell untendered Old Notes
could be adversely affected. See "Risk Factors -- Consequences of Failure to
Exchange."

     The Old 1997 Notes and the Old 1998 Notes were each issued originally in
global form (the "Global Old Notes"). The Global Old Notes were deposited with,
or on behalf of, The Depository Trust Company ("DTC"), as the initial depository
with respect to the Old Notes (in such capacity, the "Depositary"). The Global
Old Notes are registered in the name of Cede & Co. ("Cede"), as nominee of DTC,
and beneficial interests in the Global Old Notes are shown on, and transfers
thereof are effected only through, records maintained by the Depositary and its
participants. The use of the Global Old Notes to represent certain of the Old
Notes permits the Depositary's participants, and anyone holding a beneficial
interest in an Old Note registered in the name of such a participant, to
transfer interests in the Old Notes electronically in accordance with the
Depositary's established procedures without the need to transfer a physical
certificate. New Notes issued in exchange for the Global Old Notes will also be
issued initially as a note in global form (the "Global New Notes," and, together
with the Global Old Notes, the "Global Notes") and deposited with, or on behalf
of, the Depositary. After the initial issuance of the Global New Notes, New
Notes in certificated form will be issued in exchange for a holder's
proportionate interest in the appropriate Global New Note only as set forth in
the 1997 Indenture or 1998 Indenture, as applicable.

                                  THE COMPANY
 
     Verio is a leading national provider of Internet connectivity and enhanced
Internet services to small and medium sized businesses. Since its inception in
March 1996, the Company has rapidly established a national presence through the
acquisition, integration, and growth of local Internet service providers
("ISPs") with a business customer focus. Verio believes that small and medium
sized businesses represent an attractive target market for the provision of
Internet services due to this market's low current penetration levels and
customer churn rates, and the expanding Internet needs of these businesses.
Because of their limited internal technical resources, small and medium sized
businesses also typically require hands-on local support and highly reliable
turnkey solutions for mission critical applications. Verio further believes that
these needs currently are underserved by both the national and local ISPs. While
national ISPs lack the local presence to provide customized, hands-on service,
local ISPs typically lack the scale and resources required to provide dedicated,
high-capacity Internet access, around-the-clock support and tailored product
offerings at competitive prices.
 
   
     The Company believes it has a unique competitive advantage in serving small
and medium sized business customers, through the combination of the technical
competency, hands-on support and entrepreneurial culture of locally based ISPs
with the quality and economic efficiency of Verio's national network,
operational infrastructure and financial strength. Verio has quickly built
critical mass by acquiring the stock or assets of, or making significant
investments in, over 30 ISPs that provide a comprehensive range of Internet
connectivity and enhanced products and services to over 80,000 customer accounts
in 33 of the top 50 Metropolitan Statistical Areas ("MSAs") in the country, with
combined revenues of approximately $23.2 million for the three months ended
December 31, 1997. The Company integrates and optimizes the operations of its
ISPs by consolidating their operations into regional operating units with
centralized regional management, connecting their local networks to Verio's
high-speed, highly reliable national backbone, and providing them with Verio's
integrated national support services.
    
 
     Total ISP revenues in the United States are projected to grow from $3.3
billion in 1996 to $18.3 billion in 2000, according to International Data
Corporation ("IDC"). Industry analysts have reported that small and medium sized
businesses represent a potential market of over seven million customers in the
United States, and use of the Internet by this market segment is expected to
grow substantially from its current low level of market penetration. IDC
predicts that dedicated connections to the Internet for small and medium sized
businesses will grow from approximately 90,000 in 1996 to just under 800,000 in
2000, representing a 73% compounded annual growth rate. Small and medium sized
businesses generally seek an ISP with locally based personnel who are readily
available to respond in-person to technical issues, who can assist in developing
and implementing the customer's effective use of the Internet, and with whom
they can establish a stable and long-term relationship. In addition, they are
increasingly reliant on enhanced product offerings that address their specific
business needs on a cost-effective basis, allowing them to compete with larger
companies. For
 
                                        1
<PAGE>   9
 
   
example, IDC estimates Web hosting revenues from small and medium sized
businesses will grow from $84 million in 1996 to over $3.4 billion in 2000,
representing 95% of the total Web hosting market.
    
 
   
     The rapid development and growth of the Internet has resulted in a highly
fragmented industry of over 4,000 national and local ISPs in the United States,
with no dominant ISP serving the needs of small and medium sized businesses.
Independent regional and local ISPs have successfully captured approximately
one-half of this market, despite the substantially greater resources of the
national providers. However, rising costs and increasing demands from business
customers have made it more difficult for the small ISP to meet its customer's
demands on a cost-effective basis. Facing these competitive pressures, Verio
believes that independent regional and local ISPs will continue to be attracted
to and benefit from the consolidation opportunity provided by Verio.
    
 
     Internet connectivity and enhanced Internet services to small and medium
sized businesses. Key elements of the Company's strategy in accomplishing this
goal are to: (a) continue its role as the leading consolidator of independent
ISPs by acquiring additional local and regional ISPs focused on the Company's
target market; (b) integrate the operations of its ISPs and capture operational
economies of scale by leveraging its national infrastructure and support
services; (c) develop and offer additional high-margin enhanced services to
increase revenues from existing and future customers; and (d) build customer
loyalty and gain market share by expanding the Company's local technical,
distribution and service capabilities and establishing national Verio brand name
recognition.
 
   
     Verio owns and operates a national network, providing a high bandwidth,
highly reliable data transmission path connecting Verio's customers to the
Internet. The Company's national network architecture is based on a combination
of Asynchronous Transfer Mode ("ATM") and clear channel circuits operating at
DS-3 and OC-3 speeds. The network interconnects more than 15 national nodes and
over 180 local points of presence ("POPs") across the United States. The Company
believes that aggregating the bandwidth and capacity requirements of each Verio
ISP onto one national network provides operational control and efficiency,
reduces costs, provides redundancy, and results in a higher quality service,
thereby addressing some of the most significant challenges that an ISP faces in
supporting its customers. The reliability of the national network is the result
of many factors, including redundant routers and other critical hardware,
carrier class facilities at POP locations (such as back up power, fire
suppression and climate control), and redundant telecommunications lines.
Verio's national infrastructure incorporates several other elements critical to
maintaining the highest quality Internet service, such as peering relationships
with other national ISPs, sophisticated network management tools, and a
comprehensive range of national services to support its regional operations.
These services include 7-day X 24-hour customer technical support, financial
information management through a central, standardized accounting system, a
sophisticated billing and collections system, and national marketing and product
development programs. The Company continues to rollout its national
infrastructure and support services to its ISPs. Of the over 30 ISPs acquired to
date, 16 now invoice their customers through Verio's national billing service,
21 take advantage of Verio's customer technical support, 25 are linked to
Verio's national backbone, 20 utilize Verio's national accounting system, and
the network operations of 17 of these ISPs are monitored by Verio's national
Network Operations Center ("NOC").
    
 
   
     Verio believes that a critical factor in the successful implementation of
its business strategy is the quality of its management team and Board of
Directors. The Company's senior management team and Board of Directors have
previously successfully executed similar consolidation strategies and have
considerable experience in the management and growth of recurring revenue-based
telecommunications businesses. Management believes that its experience in the
deployment of similar systems and services in other emerging telecommunications
industries can be leveraged to significantly improve the quality of services
currently available in the Internet service industry.
    
 
                              RECENT DEVELOPMENTS
 
   
     Since December 31, 1997, the Company has completed the acquisition of all
of the remaining equity (each, a "Buyout") of 8 of the Verio ISPs in which Verio
did not initially acquire 100% ownership. Verio is in the process of integrating
the Verio ISPs in each region into regional operating units to capture and
promote
    
                                        2
<PAGE>   10
 
   
operational and management efficiencies and economies of scale. On March 12,
1998, the Company announced the consolidation of the Verio ISPs' operations and
marketing efforts under the Verio brand name.
    
 
   
     The Company continues to evaluate additional ISPs for investment or
acquisition. Since December 31, 1997, the Company has acquired an ISP in its
Northeast region, and has executed definitive agreements to acquire four
additional ISPs. Two of these ISPs will expand the Company's Midwest presence,
one will join the Northeast operations, and one is located in Florida and is the
Company's first acquisition in the Southeast region. With these four additional
ISPs, the Company will serve 36 of the top 50 MSAs in the U.S. The revenue
attributable to these four ISPs is estimated to be approximately $2.3 million
for the three months ended December 31, 1997, which would bring the Company's
total revenue for that three month period to $25.5 million. The Company believes
that consummation of each of these acquisitions is probable. Accordingly,
financial information for these acquisitions is reflected in the pro forma
financial statements contained herein. Nonetheless, there can be no assurance
that all of the closing conditions will be satisfied or that the Company will
consummate any or all of these acquisitions. In addition, the Company has
executed a non-binding letter of intent to acquire an additional ISP located in
Michigan which, if acquired, would further enhance the Company's market presence
in the Midwest region.
    
 
   
     On February 27, 1998, Verio filed a registration statement on Form S-1 with
respect to the proposed initial public offering of its Common Stock (the "IPO")
in an initial amount of $100.0 million. No assurance can be given that the IPO
will be consummated or, if consummated, that the amount of proceeds received or
amount of Common Stock sold by the Company will be in the amounts currently
contemplated.
    
 
   
     Mark D. Johnson, who served as the Company's President, Chief Operating
Officer and a director of the Company, died on March 9, 1998. While Mr. Johnson
played an important role in overseeing the Company's operations, the Company
does not expect that his death will adversely affect the Company's operations,
growth or financial prospects because of the strength of the Company's core
management team. Justin Jaschke, Verio's Chief Executive Officer, has been
appointed to serve as President of the Company and has assumed Mr. Johnson's
responsibilities on behalf of the Company while Verio conducts an executive
search to fill the positions that were held by Mr. Johnson.
    
 
   
     On March 25, 1998, the Company consummated the sale of the Old 1998 Notes.
In connection with the sale of the Old 1998 Notes, the Company repurchased the
$50.0 million principal amount of the Company's Old 1997 Notes held by Brooks
Fiber Properties, Inc. ("Brooks") (the "Refinancing") for an aggregate net
purchase price of approximately $54.5 million, plus accrued interest. See
"Certain Transactions."
    
 
   
     On March 31, 1998, the Company signed a long-term agreement with Qwest
Communications Corporation ("Qwest") to purchase long haul capacity and
ancillary services on Qwest's planned 16,285 mile MacroCapacity(SM) Fiber
Network. Over the first seven years of the agreement, Verio has committed to
purchase, and Qwest has committed to provide, not less than $100.0 million of
capacity and services at agreed upon prices. See "Management's Discussion and
Analysis of Financial Condition and Result of Operations -- Costs and Expenses"
and "Business -- Verio National Network." The Company will have the right to
prepay its commitment under the agreement. The Company also may order capacity
and services in excess of the commitment level, and after the seven-year
commitment term, at the agreed upon prices.
    
 
   
     On April 6, 1998, Verio signed a credit agreement providing for a $57.5
million revolving credit financing facility (the "Bank Facility"). The Chase
Manhattan Bank serves as agent for the lenders in the Bank Facility. The Company
has drawn no funds to date under the Bank Facility.
    
 
   
     On April 7, 1998, the Company executed agreements establishing a strategic
relationship with NTT. These agreements provide for an investment by NTT or one
of its affiliates in the Company (the "NTT Investment"), concurrent with and
conditioned upon the consummation of the proposed IPO, for up to 12.5% of the
Company's fully diluted Common Stock (up to a maximum investment of $100.0
million) at a 3.25% discount to the price to public in the proposed IPO. Verio
also executed a commercial services agreement with NTT's U.S. affiliate, NTT
America, Inc. ("NTT America"), under which Verio is designated as the preferred
provider of Internet access and related services to customers of NTT America on
a reseller basis. Verio and
    
 
                                        3

NTT will connect their backbones and establish a peering and transit
relationship. In conjunction with its equity investment, NTT will be entitled to
designate one member to serve on the Company's Board of Directors. See
"Business -- NTT Strategic Relationship" and "Principal Stockholders -- NTT
Investment."
    
 
   
     The Company's headquarters is located at 8005 South Chester Street, Suite

                             security interest in the Escrow Account (as
                             defined). See "Description of the 1997

Ranking....................  The Old 1997 Notes and the New 1997 Notes will be
                             senior unsecured obligations of the Issuer, ranking
                             pari passu in right of payment with all existing
                             and future unsecured and unsubordinated
                             indebtedness of the Issuer and senior in right of
                             payment to all existing and future subordinated
                             indebtedness of the Issuer. The Old 1997 Notes and
                             the New 1997 Notes will be effectively subordinated
                             to all secured indebtedness of the Issuer to the
                             extent of the value of the assets securing such
                             indebtedness and to indebtedness of subsidiaries of
                             the Issuer. As of December 31, 1997, on a pro forma
                             basis after giving effect to the Initial 1998 Notes
                             Offering there was approximately $9.6 million of
                             secured long-term indebtedness outstanding to which
                             holders of 1997 Notes were effectively subordinated
                             in right of payment and approximately $7.0 million
                             of subsidiary indebtedness to which holders of 1997
                             Notes were structurally subordinated. See
                             "Description of the 1997 Notes -- General."
    
 
Sinking Fund...............  None.
 
   
Optional Redemption........  The 1997 Notes will be redeemable at the option of
                             the Issuer, in whole or in part, at any time on or
                             after June 15, 2002, at the redemption prices set
                             forth herein, plus accrued interest thereon, if
                             any, to the date of redemption. In addition, in the
                             event that after the issue date and prior to June
                             15, 1999 the Issuer issues, in one or more
                             transactions, Capital Stock (other than
                             Disqualified Stock) of the Issuer to Brooks, which
                             was recently acquired by WorldCom, Inc.
                             ("WorldCom"), or one or more Strategic Equity
                             Investors for aggregate gross cash proceeds of
                             $50.0 million or more, the Issuer may redeem up to
                             33 1/3% of the originally issued aggregate
                             principal amount of 1997 Notes with the net
                             proceeds thereof at a redemption price of 113.5% of
                             the principal amount, together with accrued and
                             unpaid interest to the date of redemption, provided
                             that at least $100.0 million aggregate principal
                             amount of 1997 Notes are outstanding following such
                             redemption. See "Description of the 1997
                             Notes -- Redemption -- Optional Redemption."
    
 
   
Change of Control..........  Following the occurrence of a Change of Control (as
                             defined in the 1997 Indenture), the Issuer will be
                             required to make an offer to purchase the 1997
                             Notes then outstanding at a purchase price equal to
                             101% of the principal amount thereof plus accrued
                             and unpaid interest, if any, to the date of
                             purchase. Furthermore, such a Change of Control
                             would constitute a default under the Bank Facility
                             requiring the Company to repay any funds drawn
                             thereunder. The Issuer may not have available
                             sufficient funds or the financial resources
                             necessary to satisfy its obligations to repurchase
                             the 1997 Notes, to repay any funds drawn under the
                             Bank Facility, or to repay any other debt the
                             Company may have outstanding that is repayable upon
                             a Change of Control, including the 1998 Notes. See
                             "Description of the 1997 Notes -- Certain
                             Covenants -- Change of Control" and "-- Certain
                             Definitions."

                             and the Initial 1997 Notes Purchasers. This

                         DESCRIPTION OF NEW 1998 NOTES
    
 
   
     The form and terms of the New 1998 Notes will be identical in all material
respects to the form and terms of the Old 1998 Notes, except that the New 1998

Notes shall be deemed consummated upon the occurrence of the delivery by the
Issuer to the Exchange Agent of New 1998 Notes in the same aggregate principal
amount as the aggregate principal amount of Old 1998 Notes that are validly
tended by holders thereof pursuant to such Exchange Offer. See "The Exchange
Offers -- Procedures for Tendering Old Notes" and "Description of the 1998

                             ranking pari passu in right of payment with all
                             existing and future unsecured and unsubordinated
                             indebtedness of the Issuer, including the 1997
                             Notes, and senior in right of payment to all
                             existing and future subordinated indebtedness of
                             the Issuer. The Old 1998 Notes and the New 1998

                             secured indebtedness of the Issuer to the extent of
                             the value of the assets securing such indebtedness

                             subsidiaries of the Issuer. As of December 31,

                             the Initial 1998 Notes Offering, there would have
                             been approximately $9.6 million of secured
                             long-term indebtedness outstanding to which holders
                             of 1998 Notes would have been effectively
                             subordinated in right of payment and approximately
                             $7.0 million of subsidiary indebtedness to which
                             holders of 1998 Notes would have been structurally
                             subordinated. See "Description of the 1998
                             Notes -- General."

                             after April 1, 2002, at the redemption prices set
                             forth herein, plus accrued interest thereon, if
                             any, to the date of redemption. In addition, in the
                             event that after the issue date and prior to April
                             1, 2001 the Issuer issues, in one or more
                             transactions, Capital Stock (other than
                             Disqualified Stock) of the Issuer to WorldCom or

                             or more Strategic Equity Investors or in any Public
                             Equity Offering for aggregate gross cash proceeds
                             of $50.0 million or more, the Issuer may redeem, at
                             its option, up to 35% of the initially outstanding
                             aggregate principal amount of 1998 Notes with the
                             net proceeds thereof at a redemption price equal to
                             110.375% of the principal amount of the 1998 Notes,
                             together with accrued and unpaid interest thereon,
                             if any, to the date of redemption; provided that
                             not less than $113.75 million aggregate principal
                             amount of 1998 Notes is outstanding following such
                             redemption. See "Description of the 1998
                             Notes -- Redemption -- Optional Redemption."
    
 
   
Change of Control..........  Following the occurrence of a Change of Control (as
                             defined in the 1998 Indenture), the Issuer will be
                             required to make an offer to purchase all 1998
                             Notes then outstanding at a purchase price equal to
                             101% of the principal amount thereof plus accrued
                             and unpaid interest thereon, if any, to the date of
                             purchase. Furthermore, such a Change of Control
                             would constitute a default tender the Bank Facility
                             requiring the Company to repay any funds drawn
                             thereunder. The Issuer may not have available
                             sufficient funds or the financial resources
                             necessary to satisfy its obligations to repurchase
                             the 1998 Notes, to repay any funds drawn under the
                             Bank Facility, or to repay any other debt the
                             Company may have outstanding that is repayable upon
                             a Change of Control, including the 1997 Notes. See
                             "Description of the 1998 Notes -- Certain
                             Covenants -- Change of Control" and "-- Certain
                             Definitions."

                             including, among others, covenants with respect to

     Holders of the Old Notes should carefully consider the following risk
factors, as well as the other information contained in this Prospectus in
evaluating the Exchange Offers. This Prospectus contains statements which
constitute forward-looking statements within the meaning of the Private
Securities Litigation Reform Act of 1995. These statements appear in a number of
places in this Prospectus and include statements regarding the intent, belief or
current expectations of the Company, its directors or its officers primarily
with respect to the future operating performance of the Company. Holders of the
Old Notes are cautioned that any such forward-looking statements are not
guarantees of future performance and involve risks and uncertainties, and that
actual results may differ materially from those in the forward-looking
statements as a result of various factors. The accompanying information
contained in this Prospectus, including the information set forth below,
identifies important factors that could cause such differences. See
"-- Forward-Looking Statements" below.
    
 
HISTORY OF LOSSES; NO ASSURANCE OF PROFITABILITY
 
     The Company was formed in March 1996. The Company has incurred net losses
since its inception, and management expects to incur significant additional
losses as the Company continues its investment and acquisition program as well
as the building of its national network operations. Prospective investors have
limited operating and financial data about the Company upon which to base an
evaluation of the Company's performance and an investment in the Notes offered
hereby. For the period from inception to December 31, 1996 and the year ended
December 31, 1997, the Company reported net losses of $5.1 million and $46.3
million, respectively. From inception through December 31, 1997, the Company
reported cumulative cash used by operating activities of $37.6 million. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations." The Company expects to generate negative operating cash flow for at
least the next several years while it continues to acquire and invest in ISPs.
The extent to which the Company experiences negative cash flow will depend upon
a number of factors including the number and size of its acquisitions and
investments, the ability to generate increasing revenues and cash flow, the
amount of expenditures incurred at the corporate and national level, the timing
of the Buyouts and any potential adverse regulatory developments. The Company
will be dependent on various financing sources to fund its growth as well as
continued losses from operations. There can be no assurance that the Company
will achieve or sustain positive operating cash flow or generate net income in
the future. To achieve profitability, the Company must, among other things,
develop and market products and services which are accepted on a broad
commercial basis. Given the Company's limited operating history, there can be no
assurance that the Company will ever achieve broad commercial acceptance or
profitability. See "-- Competition; Pricing Fluctuations," "-- Dependence on the
Internet; Uncertain Adoption of Internet as a Medium of Commerce and
Communications" and "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Liquidity and Capital Resources."
 
SUBSTANTIAL INDEBTEDNESS; EFFECT OF FINANCIAL LEVERAGE
 
   
     The Company has indebtedness that is substantial in relation to its
stockholders' equity and cash flow. As of December 31, 1997, the Company had an
aggregate of approximately $142.3 million of long-term indebtedness outstanding,
representing 67% of total capitalization. After giving effect to the recent sale
of $175.0 million of the Company's Old 1998 Notes, the proposed IPO and the NTT
Investment, long term indebtedness would represent 53% of total capitalization.
If the proposed IPO and NTT Investment are not consummated, long term
indebtedness would represent 76% of total capitalization. In addition, the
Company recently signed the Bank Facility providing for $57.5 million of
revolving credit. See "-- Requirements for Additional Capital." As a result of
the substantial indebtedness of the Company, fixed charges of the Company are
expected to exceed its earnings for the foreseeable future. Substantial leverage
poses the risk that the Company may not be able to generate sufficient cash flow
to service its indebtedness, or to adequately fund its operations. The Company
has experienced a substantial decrease in EBITDA, from negative $5.6 million in
1996 to negative $29.7 million in 1997. Although EBITDA as a percentage of
revenue improved from negative 237% to negative 83%, there can be no assurance
that this trend will continue, or that
    
 
                                       13
<PAGE>   21
 
   
the Company will be able to increase its revenue and leverage the investments it
has made in national services and systems, the national network, and the
operating overhead of the Verio ISPs, to achieve sufficient cash flow to meet
its debt service obligations. In particular, there can be no assurance that the
Company's operating cash flow will be sufficient to pay the $13.5 million in
annual interest (beginning in June 2000 following the termination of the
interest escrow arrangement for the 1997 Notes) on the $100.0 million principal
amount of 1997 Notes outstanding after the Refinancing, to pay the $18.2 million
in annual interest on the 1998 Notes, or to meet its debt service obligations
under the Bank Facility, if drawn upon. The leveraged nature of the Company also
could limit the ability of the Company to effect future financings or may
otherwise restrict the Company's operations and growth.
    
 
HOLDING COMPANY STRUCTURE AND NEED TO ACCESS SUBSIDIARY CASH FLOWS
 
     The Issuer is a holding company with limited assets that conducts
substantially all of its revenue producing operations through its ISPs. The
Verio ISPs include wholly owned subsidiaries, less than wholly owned
subsidiaries and entities in which the Issuer has a minority interest. Claims of
holders of the Notes will be effectively subordinated to the indebtedness and
other liabilities and commitments of the Company's subsidiaries, and claims by
the Issuer as an equity holder in its non-wholly owned subsidiaries and minority
interests will be limited to the extent of the Issuer's direct or indirect
investment in such entities. The ability of the Issuer's creditors, including
the holders of the Notes, to participate in the assets of any of the Verio ISPs
upon any liquidation or bankruptcy of any such entity will be subject to the
prior claims of that entity's creditors, including trade creditors, and any
prior or equal claim of any other equity holder. The claims of holders of Notes
would have been effectively subordinated to approximately $9.6 million of
indebtedness of the Issuer's subsidiaries as of December 31, 1997. In addition,
the ability of the Issuer's creditors, including the holders of Notes, to
participate in distributions of assets of the Verio ISPs will be limited to the
extent that the outstanding shares of any of its ISPs are either pledged to
secure other creditors (which is currently contemplated under the proposed Bank
Facility) or are not owned by the Issuer. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."
 
     The Notes will be obligations solely of the Issuer. The ability of the
Issuer to pay interest on the Notes or to repay the Notes at maturity or
otherwise will be dependent upon the cash flows of its ISPs and the payment of
funds by the Verio ISPs to the Issuer in the form of repayment of loans,
dividends, management fees or otherwise. The Verio ISPs have no obligation,
contingent or other, to pay amounts pursuant to the Notes or to make funds
available therefor, whether in the form of loans, dividends or other
distributions. Accordingly, the Issuer's ability to repay the Notes at maturity
or otherwise may be dependent upon the Issuer's ability to refinance the Notes
which will depend, in large part, upon factors beyond the control of the Issuer.
The agreements governing future indebtedness of the Verio ISPs may contain
covenants prohibiting them from distributing or advancing funds to the Issuer
under certain circumstances, including to fund interest payments in respect of
the Notes. In addition, the practical effect of the Issuer's status as a
minority shareholder of certain ISPs may limit the ability of those ISPs to make
funds available to the Issuer.
 
REQUIREMENTS FOR ADDITIONAL CAPITAL
 
   
     The Company's operations have required and will continue to require
substantial capital for investments in ISP operations, including the acquisition
of or investments in additional ISPs, the deployment of the Company's national
network and infrastructure and the funding of capital expenditures for expansion
of services and operating losses. The Company may need additional amounts to
fund its operating losses and those of the Verio ISPs, which amounts cannot be
determined. Over the longer term, it is likely that the Company will require
substantial additional funds to continue to fund the Company's investment and
acquisition program as well as product development, marketing, sales and
customer support capabilities. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources."
    
 
     The Company expects to meet its additional capital needs with the proceeds
from sales or issuance of equity securities, credit facilities and other
borrowings, and sales of additional debt securities. The failure to
                                       14
<PAGE>   22
 
   
raise and generate sufficient funds may require the Company to delay or abandon
some of its planned future expansion or expenditures, which could have a
material adverse effect on the Company's growth and its ability to compete in
the Internet industry. No assurance can be given that the Company will have
sufficient cash flow available to maintain its current or future growth plans or
operations.
    
 
     On February 27, 1998, Verio filed a registration statement on Form S-1 with
respect to the proposed IPO. No assurance can be given that the IPO will be
consummated or, if consummated, that the amount of proceeds received by the
Company, or the amount of Common Stock sold by the Company, will be in the
amounts currently contemplated.
 
COMPETITION; PRICING FLUCTUATION
 
     The market for Internet connectivity and related services is extremely
competitive. The Company anticipates that competition will continue to intensify
as the use of the Internet grows. The tremendous growth and potential market
size of the Internet access market has attracted many new start-ups as well as
existing businesses from different industries. Current and prospective
competitors include, in addition to other national, regional and local ISPs,
long distance and local exchange telecommunications companies, cable television
companies, direct broadcast satellite and wireless communications providers, and
on-line service providers.
 
   
     The Company believes that a reliable national network, knowledgeable
salespeople and the quality of technical support currently are the primary
competitive factors in the Company's targeted markets, and that price is usually
secondary to these factors.
    
 
     The Company's current primary competitors include other ISPs with a
significant national presence which focus on business customers, such as UUNet,
GTE Internetworking (formerly BBN), PSINet, Concentric Network and DIGEX. While
the Company believes that its level of local service and support and target
market focus distinguish it from these competitors, some of these competitors
have a significantly greater market presence, brand recognition, and financial,
technical and personnel resources than the Company, and have extensive
coast-to-coast Internet backbones. The Company also competes with unaffiliated
regional and local ISPs in its targeted geographic regions.
 
     All of the major long distance companies (also known as interexchange
carriers or IXCs), including AT&T, MCI, and Sprint, offer Internet access
services and compete with the Company. The recent sweeping reforms in the
federal regulation of the telecommunications industry have created greater
opportunities for local exchange carriers ("LECs"), including the Regional Bell
Operating Companies ("RBOCs"), to enter the Internet connectivity market. In
order to address the Internet connectivity requirements of the current business
customers of long distance and local carriers, the Company believes that there
is a move toward horizontal integration through acquisitions of, joint ventures
with, and the wholesale purchase of connectivity from, ISPs. The
WorldCom/MFS/UUNet consolidation, the NETCOM/ICG merger, the Intermedia/DIGEX
merger and GTE's acquisition of BBN are indicative of this trend. Accordingly,
Verio expects that it will experience increased competition from the traditional
telecommunications carriers. Many of these telecommunications carriers, in
addition to their substantially greater network coverage, market presence, and
financial, technical and personnel resources, also have large existing
commercial customer bases. Furthermore, telecommunications providers may have
the ability to bundle Internet access with basic local and long distance
telecommunications services. Such bundling of services may have an adverse
effect on the Company's ability to compete effectively with the
telecommunications providers and may result in pricing pressure on the Company
that would have an adverse effect on the Company's business, financial condition
and results of operations.
 
     Many of the major cable companies have announced that they are exploring
the possibility of offering Internet connectivity, relying on the viability of
cable modems and economical upgrades to their networks. MediaOne Group and TCI
have recently announced trials to provide Internet cable service to their
residential customers in select areas. Several announcements also have recently
been made by other alternative service companies approaching the Internet
connectivity market with various wireless terrestrial and satellite-based
service technologies. These include Hughes Network System's DirecPC that
provides high-speed data through direct broadcast satellite technology; CAI
Wireless System's announcement of an MMDS wireless
                                       15
<PAGE>   23
 
cable operator launching data services via 2.5 to 2.7 GHz and high-speed
wireless modem technology; Cellularvision's announcement that it is offering
Internet access via high-speed wireless LMDS technology; and Winstar, which
currently offers high-speed Internet access to business customers over the 38
GHz spectrum.
 
     The predominant on-line service providers, including America Online,
CompuServe, Microsoft Network, and Prodigy, have all entered the Internet access
business by engineering their current proprietary networks to include Internet
access capabilities. The Company competes to a lesser extent with these on-line
service providers.
 
     Recently, there have been several announcements regarding the planned
deployment of broadband services for high speed Internet access by cable and
telephone companies through new technologies such as cable modems and xDSL.
While these providers have initially targeted the residential consumer, it is
likely that their target markets will expand to encompass the Company's target
markets, which may significantly affect the pricing of the Company's service
offerings.
 
   
     As a result of an increase in the number of competitors, and vertical and
horizontal integration in the industry, the Company currently encounters and
expects to encounter significant pricing pressure and other competition in the
future. Advances in technology as well as changes in the marketplace and the
regulatory environment are constantly occurring, and the Company cannot predict
the effect that ongoing or future developments may have on the Company or the
pricing of its products and services. See "-- Fluctuations in Operating
Results," "-- Dependence on the Internet; Uncertain Adoption of Internet as a
Medium of Commerce and Communication" and "-- Potential Liability for
Information Disseminated Over Network; Regulatory Matters."
    
 
MANAGEMENT OF GROWTH; INTEGRATION OF ACQUISITIONS AND INVESTMENTS
 
     The Company is currently experiencing a period of rapid expansion with the
acquisition and integration of its ISPs. The rapid growth of the Company's
business and its product and service offerings has placed, and is likely to
continue to place, a significant strain on the Company's managerial, operating,
financial and other resources. The Company's future performance will depend, in
part, upon its ability to manage its growth effectively, which will require that
the Company implement additional management information systems capabilities,
further develop its operating, administrative and financial and accounting
systems and controls, improve coordination between engineering, accounting,
finance, marketing and operations, and hire and train additional personnel.
Failure by the Company to develop adequate operational and control systems or to
attract and retain highly qualified management, financial, technical, sales and
marketing and customer care personnel could materially adversely affect the
Company's ability to integrate the ISPs it has acquired and continues to
acquire. While the Company anticipates that it will recognize various economies
and efficiencies of scale as a result of the Buyouts and the integration of the
businesses of the Verio ISPs, the process of consolidating the businesses and
implementing the strategic integration of the Company and its ISPs, even if
successful, may take a significant period of time, will place a significant
strain on the Company's resources, and could subject the Company to additional
expenses during the integration process. Furthermore, the Company's performance
will depend on the internal growth generated through ISP operations. As a
result, there can be no assurance that the Company will be able to integrate the
Verio ISPs successfully or in a timely manner in accordance with its strategic
objectives. Failure to integrate its ISPs or to manage effectively the growth of
the Company would have a material adverse effect on the Company's business,
financial condition and results of operations.
 
DEPENDENCE UPON IMPLEMENTATION OF NETWORK INFRASTRUCTURE; ESTABLISHMENT AND
MAINTENANCE OF PEERING RELATIONSHIPS
 
     The Company's success will depend upon its ability to complete the
implementation of and to continue to expand its national network infrastructure
and support services in order to supply sufficient geographic reach, capacity,
reliability and security 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
 
                                       16
<PAGE>   24
 
conditions, with the 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. See "Business
- -- Verio National Network -- Peering Relationships."
 
     In addition, the establishment and maintenance of peering relationships
with other ISPs is necessary in order to exchange traffic with other ISPs
without having to pay transit costs. The basis on which the large national ISPs
make peering available or impose settlement charges is evolving as the provision
of Internet access and related services has expanded and the dominance of a
small group of national ISPs has driven corporate peering policies. Recently,
companies that have previously offered peering have cut back or eliminated
peering relationships and are establishing new, more restrictive criteria for
peering. Furthermore, if increasing requirements associated with maintaining
peering with the major national ISPs develop, the Company may have to comply
with those additional requirements in order to continue to maintain its peering
relationships. The Company also anticipates that future expansions and
adaptations 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' product and service
requirements. 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 industry's evolving standards or
its customers' growing demands and changing requirements on a timely basis, at a
commercially reasonable cost, or at all, or that the Company will be able to
deploy successfully any expanded and adapted network infrastructure. Failure to
maintain peering relationships or establish new ones, if necessary, would cause
the Company to incur additional operating expenditures which would have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
CHALLENGES OF GROWTH BY ACQUISITIONS
 
     The Company's business strategy is dependent, in part, upon its ability to
continue to successfully identify and acquire ISPs that meet the Company's
investment criteria. The Company is continuing to seek and evaluate qualified
ISP candidates in order to optimize its market presence in the regions it
currently serves, and to expand its focus to encompass the remaining top 50 MSAs
not currently served by the Verio ISPs. In pursuing these opportunities, the
Company may compete with other communications companies with similar acquisition
strategies, many of which may be larger and have greater financial and other
resources than the Company. Competition for independent ISPs is based on a
number of factors, including price, terms and conditions, size and access to
capital, ability to offer cash, stock, or other forms of consideration and other
matters. No assurance can be given that the Company will be able to successfully
identify suitable ISPs or, once identified, will be able to consummate an
acquisition of or an investment in those targeted ISPs on terms and conditions
acceptable to the Company. See "Business -- The Verio Strategy" and "--
Competition; Pricing Fluctuation." Further, the Company's ability to consummate
transactions with ISPs that it identifies will require significant financial
resources. Failure to raise and generate sufficient funds may require the
Company to delay or abandon some of its planned future expansion or
expenditures, which could have a material adverse effect on the Company's
growth. See "-- Requirements for Additional Capital."
 
FLUCTUATIONS IN OPERATING RESULTS
 
     The Company's operating results have fluctuated in the past and may in the
future fluctuate significantly depending upon a variety of factors, including
the incurrence of capital costs and costs associated with the Buyouts and the
introduction of value-added enhanced services and new services by the Company.
Additional factors that may contribute to variability of operating results
include: the pricing and mix of services offered by the Company; customer
retention rate; changes in pricing policies and product offerings by the
Company's competitors; growth in demand for network and Internet access
services; one-time costs associated with regional consolidation; and general
telecommunications services' performance and availability. The Company has also
experienced seasonal variation in Internet use and, therefore, revenue streams
may fluctuate accordingly. In response to competitive pressures, the Company may
take certain pricing or marketing actions that could have a material adverse
effect on the Company's business, financial condition and results of
 
                                       17

operations. See "-- Competition; Pricing Fluctuation." As a result, variations
in the timing and amounts of revenues could have a material adverse effect on
the Company's quarterly operating results. Due to the foregoing factors, the
Company believes that period-to-period comparisons of its operating results are
not necessarily meaningful and that such comparisons cannot be relied upon as
indicators of future performance. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
    
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company is highly dependent upon the efforts of its senior management
team, the loss of any of whom could impede the achievement of product
development and marketing objectives and would have a material adverse effect on
the Company. The Company believes that its future success will depend in large
part on its ability to attract and retain qualified technical and marketing
personnel for whom there is intense competition in the areas of the Company's
activities. There can be no assurance that the Company will be able to attract
and retain the personnel necessary for the development and integration of its
business. Delays in hiring such personnel could delay the achievement of
development and marketing objectives. The loss of the services of key personnel
or the failure to attract additional personnel as required could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
RISK OF SYSTEM FAILURE
 
     The Company's operations are dependent upon its ability to protect its
network infrastructure against damage from fire, earthquakes, floods, power
loss, telecommunications failures and similar events or to construct networks
that are not vulnerable to the effects of such events. Significant portions of
the Company's computer equipment, including components critical to the operation
of its Internet backbone, are located at the Company's facility in Englewood,
Colorado and the Company's NOC located in Dallas, Texas. Despite precautions
taken by and planned by the Company, the occurrence of a natural disaster or
other unanticipated problem at the Company's NOC or at a number of the Company's
national nodes could cause interruptions in the services provided by the
Company. The failure of a local POP would result in interruption of service to
the customers served by such POP until necessary repairs were effected or
replacement equipment were installed. Additionally, failure of the Company's
telecommunications providers to provide the data communications capacity
required by the Company as a result of natural disaster, operational disruption
or for any other reason could cause interruptions in the services provided by
the Company. Any damage or failure that causes interruptions in the Company's
operations could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
SECURITY RISKS
 
     Despite the implementation of security measures by the Company, networks
are vulnerable to unauthorized access, computer viruses and other disruptive
problems. ISPs have in the past experienced, and may in the future experience,
interruptions in service as a result of the accidental or intentional actions of
Internet users, current and former employees or others. Unauthorized access
could also potentially jeopardize the security of confidential information
stored in the computer systems of the Company and its customers, which may
result in liability of the Company to its customers and also may deter potential
subscribers. Although the Company intends generally to continue to implement
industry-standard security measures, such measures have been circumvented in the
past, and there can be no assurance that measures implemented by the Company
will not be circumvented in the future. 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 and results of
operations.
 
DEPENDENCE ON THE INTERNET; UNCERTAIN ADOPTION OF INTERNET AS A MEDIUM OF
COMMERCE AND COMMUNICATIONS
 
     The Company's products and services are targeted toward users of the
Internet, which has experienced rapid growth. As is typical in the case of a new
and rapidly evolving industry characterized by rapidly changing technology,
evolving industry standards and frequent new product and service introductions,
demand and
                                       18
<PAGE>   26
 
market acceptance for recently introduced products and services are subject to a
high level of uncertainty. In addition, critical issues concerning the
commercial use of the Internet remain unresolved and may impact the growth of
Internet use, especially in the business market targeted by the Company. Despite
growing interest in the many commercial uses of the Internet, many businesses
have been deterred from purchasing Internet access services for a number of
reasons, including, among others, inconsistent quality of service, lack of
availability of cost-effective, high-speed options, a limited number of local
access points for corporate users, inability to integrate business applications
on the Internet, the need to deal with multiple and frequently incompatible
vendors, inadequate protection of the confidentiality of stored data and
information moving across the Internet, and a lack of tools to simplify Internet
access and use. In particular, numerous published reports have indicated that a
perceived lack of security of commercial data, such as credit card numbers, has
significantly impeded commercial exploitation of the Internet to date, and there
can be no assurance that encryption or other technologies will be developed that
satisfactorily address these security concerns. Published reports have also
indicated that capacity constraints caused by growth in the use of the Internet
may, unless resolved, impede further development of the Internet to the extent
that users experience delays, transmission errors and other difficulties.
Further, the adoption of the Internet for commerce and communications,
particularly by those individuals and enterprises which have historically relied
upon alternative means of commerce and communication, generally requires the
understanding and acceptance of a new way of conducting business and exchanging
information. In particular, enterprises that have already invested substantial
resources in other means of conducting commerce and exchanging information may
be particularly reluctant or slow to adopt a new strategy that may make their
existing personnel and infrastructure obsolete.
 
     The Company is also at risk as a result of fundamental technological
changes in the way Internet solutions may be marketed and delivered. Integrating
technological advances may require substantial time and expense, and there can
be no assurance that the Company will succeed in adapting its network
infrastructure. While the Company believes that its plan of combining the scale
and scope of a national operation with the local presence of its ISP operations
offers significant advantages for commerce and communication over the Internet,
there can be no assurance that commerce and communication over the Internet will
become widespread, or that the Company's offered Internet access and
communications services will become widely adopted for these purposes. The
failure of the market for business-related Internet solutions to continue to
develop would adversely impact the Company's business, financial condition and
results of operations.
 
     In addition, new technologies or industry standards have the potential to
replace or provide lower cost alternatives to the Company's existing products
and services. The adoption of such new technologies or industry standards could
render the Company's existing products and services obsolete and unmarketable.
For example, the Company's services rely on the continued widespread commercial
use of Transmission Control Protocol/Internet Protocol ("TCP/IP"). Alternative
open and proprietary protocol standards that compete with TCP/IP, including
proprietary protocols developed by IBM and Novell, Inc., have been or are being
developed. If the market for Internet access services fails to develop, develops
more slowly than expected, or becomes saturated with competitors, or if the
Internet access and services offered by the Company and its ISPs are not broadly
accepted, the Company's business, operating results and financial condition will
be materially adversely affected.
 
POTENTIAL LIABILITY FOR INFORMATION DISSEMINATED OVER NETWORK; REGULATORY
MATTERS
 
     The law relating to liability of on-line service providers and ISPs for
information carried on or disseminated through their networks is currently
unsettled. A number of lawsuits have sought to impose such liability for
defamatory speech and infringement of copyrighted materials. Although some
courts have ruled that the 1996 Telecommunications Act immunizes ISPs from
liability for defamatory material carried on their facilities, there can be no
assurance that other courts will take a similar approach. In one case, a state
court held that an on-line service provider could be found liable for defamatory
materials provided through its service, on the ground that the service provider
exercised active editorial control over postings to its service. Other courts
have held that on-line service providers and ISPs may, under certain
circumstances, be subject to damages for copying or distributing copyrighted
materials. Although the Supreme Court has declared the Communications Decency
Act ("CDA") to be unconstitutional as it applies to the transmission of indecent
 
                                       19
<PAGE>   27
 
on-line communications to minors, state and federal statutes continue to
prohibit the on-line distribution of obscene materials. The imposition upon ISPs
or Web server hosts of potential liability for materials carried on or
disseminated through their systems could require the Company to implement
measures to reduce its exposure to such liability. Such measures may require the
expenditure of substantial resources or the discontinuation of certain product
or service offerings, any of which could have a material adverse effect on the
Company's business, operating results and financial condition.
 
     Although the Company is not currently subject to direct regulation by the
Federal Communications Commission (the "FCC") or any other federal or state
agency, changes in the regulatory environment relating to the Internet
connectivity market, including regulatory changes which directly or indirectly
affect telecommunications costs or increase the likelihood or scope of
competition from the RBOCs or other telecommunications companies, could affect
the prices at which the Company may sell its services. For example, proposed
regulations at the FCC would require discounted Internet connectivity rates for
schools and libraries. Also, the FCC is considering whether ISPs should be
required to pay access charges to local telephone companies for each minute that
dial up users spend connected to ISPs through telephone company switches, and
some telephone companies have requested similar relief from state regulatory
commissions. The imposition of access charges would affect the Company's costs
of serving dial up customers and could have a material adverse effect on the
Company's business, operating results and financial condition.
 
DEPENDENCE UPON SUPPLIERS; LIMITED SOURCES OF SUPPLY
 
   
     The Company relies on other companies to supply certain key components of
its network infrastructure, including telecommunications services and networking
equipment which, in the quantities and quality demanded by the Company, are
available only from limited sources. For example, the Company currently relies
on Cisco Systems to supply routers critical to the Company's network, and the
Company could be adversely affected if routers from Cisco were to become
unavailable on commercially reasonable terms. Sprint, MCI and MFS, which are
competitors of the Company, are the Company's primary providers of data
communications facilities and network capacity. The Company also is dependent
upon LECs, which often are competitors of the Company, to provide
telecommunications services and lease physical space to the Company for routers,
modems and other equipment. The Company has from time to time experienced delays
in receiving telecommunications services, which can lead to the loss of
customers or prospective customers. There can be no assurance that, on an
ongoing basis, the Company will be able to obtain such services on the scale and
within the time frames required by the Company at a commercially reasonable
cost, or at all. Failure to obtain or to continue to make use of such services
would have a material adverse effect on the Company's business, operating
results and financial condition.
    
 
FINANCIAL INFORMATION CONCERNING COMPLETED AND PROBABLE ACQUISITIONS
 
     The regional ISPs targeted by the Company for acquisition typically do not
have audited financial statements and have varying degrees of internal controls
and detailed financial information. The pro forma financial information in this
Prospectus includes financial information concerning certain completed and
probable acquisitions for which audited financial statements are not presently
available. These companies are included in the "Pro Forma Financial Statements."
While the Company believes such information to be reliable, the Company has only
recently acquired certain of the companies and is still in the process of
performing its due diligence investigations of the other companies. There can be
no assurance that the Company's due diligence investigations and subsequent
audit will not reveal matters of significance, including with respect to
liabilities, contingent or otherwise, of these companies.
 
LACK OF PUBLIC MARKET
 
     The New Notes constitute a new issue of securities, have no established
trading market and may not be widely distributed. The Initial Purchasers have
informed the Company that they currently intend to make a market in the New
Notes as permitted by applicable laws and regulations, however, the Initial
Purchasers are not obligated to do so and may discontinue market making at any
time without notice. In addition, such market-making will be subject to the
limits imposed by the Securities Act and the Exchange Act and may be
                                       20
<PAGE>   28
 
   
limited during the respective Exchange Offers and the pendency of any shelf
registration statement. There can be no assurance as to the development of any
market or liquidity of any market that may develop for the New Notes. If a
market does develop, the New Notes may trade at prices lower than the initial
offering price thereof and liquidity may be limited. If a market for the New
Notes does not develop, purchasers may be unable to resell such securities for
an extended period of time, if at all. Further, the liquidity of, and trading
market for, the New Notes may also be materially and adversely affected by
declines in the market for high-yield securities generally. Such a decline may
materially and adversely affect such liquidity and tracking independently of the
financial performance of, and prospects for, the Company. The Company does not
intend to apply for listing of the New Notes on any securities exchange or for
quotation through the Nasdaq National Market.
    
 
   
RESTRICTIONS ON EXCHANGE OFFERS
    
 
   
     Issuance of New Notes in exchange for Old Notes pursuant to the Exchange
Offers will be made only after timely receipt by the Exchange Agent of a
properly completed and duly executed Letter of Transmittal, including all other
documents required by such Letter of Transmittal. Therefore, holders of Old
Notes desiring to tender such Old Notes in exchange for New Notes should allow
sufficient time to ensure timely delivery. The Exchange Agent and the Company
are under no duty to give notification of defects or irregularities with respect
to the tenders of Old Notes for exchange. Each broker-dealer that receives New
Notes for its own account pursuant to the Exchange Offers must acknowledge that
it will deliver a prospectus in connection with any resale of such New Notes.
See "The Exchange Offers -- Resales of the New Notes" and "Plan of
Distribution."
    
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
   
     Holders of Old Notes who do not exchange their Old Notes for New Notes
pursuant to the Exchange Offers will continue to be subject to the restrictions
on transfer of such Old Notes as set forth in the legend thereon as a
consequence of the issuance of the Old 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 Old Notes may not be
offered or sold, unless registered under the Securities Act, except pursuant to
an exemption from, or in a transaction not subject to, the Securities Act and
applicable state securities laws. The Company does not currently anticipate that
it will register the Old Notes under the Securities Act. To the extent that Old
Notes are tendered and accepted in the Exchange Offers, the trading market for
untendered and tendered but unaccepted Old Notes could be adversely affected.
Generally, the rights of holders of Old Notes under the 1997 Notes Registration
Rights Agreement or 1998 Notes Registration Rights Agreement, as the case may
be, would also terminate with respect to Old Notes which are not exchanged for
New Notes in the Exchange Offers.
    
 
YEAR 2000 COMPLIANCE
 
     Currently, many computer systems and software products are coded to accept
only two digit entries in the date code field. These date code fields will need
to accept four digit entries to distinguish 21st century dates from 20th century
dates. As a result, many companies' software and computer systems may need to be
upgraded or replaced in order to comply with such "Year 2000" requirements. The
Company and third parties with which the Company does business rely on numerous
computer programs in their day to day operations. The Company is evaluating the
Year 2000 issue as it relates to the Company's internal computer systems and
third party computer systems with which the Company interacts. The Company
expects to incur internal staff costs as well as consulting and other expenses
related to these issues; these costs will be expensed as incurred. In addition,
the appropriate course of action may include replacement or an upgrade of
certain systems or equipment at a substantial cost to the Company. There can be
no assurance that the Year 2000 issues will be resolved in 1998 or 1999. The
Company may incur significant costs in resolving its Year 2000 issues. If not
resolved, this issue could have a significant adverse impact on the Company's
business, operating results and financial condition.

FORWARD-LOOKING STATEMENTS
 
   
     The statements contained in this Prospectus that are not historical fact
are "forward-looking statements" (as such term is defined in the Reform Act),
which can be identified by the use of forward-looking terminology such as
"believes," "expects," "may," "will," "should," or "anticipates" or the negative
thereof or other variations thereon or comparable terminology, or by discussions
of strategy that involve risks and uncertainties. Management wishes to caution
the reader that these forward-looking statements such as the timing, costs and
scope of its acquisition of, or investments in, existing ISPs, the revenue and
profitability levels of the ISPs in which it invests, the anticipated reduction
in operating costs resulting from the integration and optimization of those
ISPs, and other matters contained above and herein in this Prospectus regarding
matters that are not historical facts, are only predictions. No assurance can be
given that the future results indicated, whether expressed or implied, will be
achieved. While sometimes presented with numerical specificity, these
projections and other forward-looking statements are based upon a variety of
assumptions relating to the business of the Company, which, although considered
reasonable by the Company, may not be realized. Because of the number and range
of the assumptions underlying the Company's projections and forward-looking
statements, many of which are subject to significant uncertainties and
contingencies that are beyond the reasonable control of the Company, some of the
assumptions inevitably will not materialize and unanticipated events and
circumstances may occur subsequent to the date of this Prospectus. These
forward-looking statements are based on current expectations, and the Company
assumes no obligation to update this information. Therefore, the actual
experience of the Company and results achieved during the period covered by any
particular projections or forward-looking statements may differ substantially
from those projected. Consequently, the inclusion of projections and other
forward-looking statements should not be regarded as a representation by the
Company or any other person that these estimates and projections will be
realized, and actual results may vary materially. There can be no assurance that
any of these expectations will be realized or that any of the forward-looking
statements contained herein will prove to be accurate.

  1998 Notes
    
 
   
     The Old 1998 Notes were sold by the Issuer to the Initial 1998 Notes
Purchasers on March 25, 1998. The Initial 1998 Notes Purchasers subsequently
resold the Old 1998 Notes in reliance on Rule 144A under the Securities Act. The
Issuer and the Initial 1998 Notes Purchasers entered into the 1998 Notes
Registration Rights Agreement, pursuant to which the Issuer agreed, with respect
to the Old 1998 Notes and subject to the Issuer's determination that the
Exchange Offer with respect to the 1998 Notes is permitted under applicable law,
to (i) cause to be filed, on or prior to June 23, 1998, a registration statement
with the Commission under the Securities Act concerning the Exchange Offer with
respect to the 1998 Notes, and (ii) use its best efforts (a) to cause such
registration statement to be declared effective by the Commission on or prior to
August 21, 1998, and (b) to consummate the Exchange Offer with respect to the
1998 Notes on or prior to September 21, 1998. The Issuer will keep the Exchange
Offer with respect to the 1998 Notes open for a period of not less than 30 days
(or longer if required by applicable law) after the date the notice of the
Exchange Offer with respect to the 1998 Notes is mailed to the holders of the
Old 1998 Notes. The Exchange Offer with respect to the Old 1998 Notes is
intended to satisfy the Issuer's exchange offer obligations under the 1998 Notes
Registration Rights Agreement.
    
 
CONSEQUENCES OF FAILURE TO EXCHANGE OLD NOTES
 
   
     Following the expiration of the respective Exchange Offers, holders of Old
Notes not tendered, or not properly tendered, will not have any further
registration rights and such Old Notes will continue to be subject to the
existing restrictions on transfer thereof. Accordingly, the liquidity of the
market for a holder's Old Notes could be adversely affected upon expiration of
the Exchange Offer with respect to such Old Notes if such holder elects not to
participate in such Exchange Offer.
    
 
   
TERMS OF THE EXCHANGE OFFERS
    
 
   
     The Issuer hereby offers, upon the terms and subject to the conditions set
forth herein and in the accompanying Letter of Transmittal, to exchange up to
(i) $100 million aggregate principal amount of New 1997 Notes for up to $100.0
million aggregate principal amount of the outstanding Old 1997 Notes and (ii) up
to $175.0 million aggregate principal amount of New 1998 Notes for up to $175.0
million aggregate principal amount of the outstanding Old 1998 Notes. The Issuer
will accept for exchange any and all Old Notes that are validly tendered on or
prior to 5:00 p.m., New York City time, on the Expiration Date. The Issuer will
issue $1,000 principal amount of New Notes in exchange of each $1,000 principal
amount of outstanding Old Notes accepted in the respective Exchange Offers.
Holders may tender some or all of their Old Notes pursuant to the Exchange
Offers. However, Old Notes may be tendered only in integral multiples of $1,000.
Tenders of the Old Notes may be withdrawn at any time prior to 5:00 p.m., New
York City time, on the Expiration Date with respect to the Exchange Offer
applicable to such Old Notes. The Exchange Offers are not conditioned upon any
minimum principal amount of Old Notes being tendered for exchange. However, the
Exchange Offers are subject to the terms and provisions of the 1997 Notes
Registration Rights Agreement and the 1998 Notes Registration Rights Agreement,
as applicable. See "-- Conditions of the Exchange Offers."
    
 
   
     As of the date of this Prospectus, (i) $100.0 million in aggregate
principal amount of the Old 1997 Notes is outstanding and (ii) $175.0 million in
aggregate principal amount of Old 1998 Notes is outstanding. As of
               , there were           registered holders of the Old Notes, and
          DTC participants. Only a holder of the Old Notes (or such holder's
legal representative or attorney-in-fact) may participate in the applicable
Exchange Offer. There will be no fixed record date for determining holders of
the Old Notes entitled to participate in the applicable Exchange Offer. The
Issuer believes that, as of the date of this Prospectus, no holder of Old Notes
is an affiliate (as defined in Rule 405 under the Securities Act) of the Issuer.
    
 
     The Issuer shall be deemed to have accepted validly tendered Old Notes
when, as and if the Issuer has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
of Old Notes and for the purposes of receiving the New Notes from the Issuer.
 
                                       23
<PAGE>   31
 
     If any tendered Old Notes are not accepted for exchange because of an
invalid tender, the occurrence of certain other events set forth herein or
otherwise, certificates for any such unaccepted Old Notes will be returned,
without expense, to the tendering holder thereof as promptly as practicable
after the Expiration Date.
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
   
     The Expiration Date shall be             , 1998 at 5:00 p.m., New York City
time, unless the Issuer, in its sole discretion, extends one or both of the
Exchange Offers, in which case the Expiration Date shall be the latest date and
time to which the applicable Exchange Offer is extended. The Company has no
obligation to make the Exchange Offers coterminous.
    
 
   
     In order to extend one or both the Exchange Offers, the Issuer will notify
the Exchange Agent of any extension by oral or written notice and will make a
public announcement thereof, each prior to 9:00 a.m., New York City time, on the
next business day after the previously scheduled Expiration Date.
    
 
   
     The Issuer reserves the right, in its sole discretion, (i) to delay
accepting any Old Notes, (ii) to extend one or both the Exchange Offers, in
which event the term "Expiration Date" shall mean the latest time and date to
which one or both of the Exchange Offers is extended, as the case may be, and
(iii) to amend the terms of the Exchange Offers in any manner. If one or both of
the Exchange Offers is amended in a manner determined by the Issuer to
constitute a material change, the Issuer will promptly disclose such amendments
by means of a prospectus supplement that will be distributed to the registered
holders of the Old Notes subject to such Exchange Offer. Modifications of an
Exchange Offer, including but not limited to extension of the period during
which the Exchange Offer is open, may require that at least five business days
remain in such Exchange Offer. In order to extend an Exchange Offer, the Issuer
will notify the Exchange Agent of any extension by oral or written notice and
will make a public announcement thereof, each prior to 9:00 a.m., New York City
time, on the next business day after the previously scheduled Expiration Date
with respect to such Exchange Offer.
    
 
   
CONDITIONS OF THE EXCHANGE OFFERS
    
 
   
     The Exchange Offers are not conditioned upon any minimum principal amount
of the Old Notes being tendered for exchange. However, the Exchange Offers are
conditioned upon the declaration by the Commission of the effectiveness of the
Registration Statement of which this Prospectus constitutes a part.

PROCEDURES FOR TENDERING OLD NOTES
 
   
     The tender of a holder's Old Notes as set forth below and the acceptance
thereof by the Issuer will constitute a binding agreement between the tendering
holder and the Issuer upon the terms and subject to the conditions set forth in
this Prospectus and in the accompanying Letter of Transmittal. Except as set
forth below, a holder who wishes to tender Old Notes for exchange pursuant to
the applicable Exchange Offer must transmit such Old Notes, together with a
properly completed and duly executed Letter of Transmittal, including all other
documents required by such Letter of Transmittal, to the Exchange Agent at the
address set forth on the back cover page of this Prospectus prior to 5:00 p.m.,
New York City time, on the Expiration Date. THE METHOD OF DELIVERY OF OLD NOTES,
LETTERS OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS IS AT THE ELECTION AND
RISK OF THE HOLDER. IF SUCH DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT
REGISTERED MAIL, PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, BE USED.
INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT THE HOLDER USE AN OVERNIGHT
OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO
ENSURE TIMELY DELIVERY.
    
 
     Any financial institution that is a participant in DTC's Book-Entry
Transfer Facility system may make book-entry delivery of the Old Notes by
causing DTC to transfer such Old Notes into the Exchange Agent's account in
accordance with DTC's procedures for such transfer. In connection with a
book-entry transfer, a Letter of Transmittal need not be transmitted to the
Exchange Agent, provided that the book-entry transfer procedure is made in
accordance with DTC's ATOP (as defined below) procedures for transfer and such
procedures are complied with prior to 5:00 p.m., New York City time, on the
Expiration Date.
 
   
     DTC's Automated Tender Offer Program ("ATOP") is the only method of
processing exchange offers through DTC. To accept the applicable Exchange Offer
through ATOP, participants in DTC must send electronic instructions to DTC
through DTC's communication system, prior to 5:00 p.m., New York City time, on
the Expiration Date, in place of sending a signed, hard copy Letter of
Transmittal. DTC is obligated to communicate those electronic instructions to
the Exchange Agent by an "Agent's Message." To tender Old Notes through ATOP,
the electronic instructions sent to DTC and transmitted by DTC to the Exchange
Agent must contain the participant's acknowledgement of its receipt of and
agreement to be bound by the Letter of Transmittal for such Old Notes.
    
 
     Each signature on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed unless the Old Notes surrendered for exchange
pursuant hereto are tendered (i) by a registered holder of the Old Notes who has
not completed either the box entitled "Special Exchange Instructions" or the box
entitled "Special Delivery Instructions" in the Letter of Transmittal, or (ii)
by an Eligible Institution (as defined below). In the event that a signature on
a Letter of Transmittal or a notice of withdrawal, as the case may be, is
required to be guaranteed, such guarantee must be by a firm which is a member of
a registered national securities exchange or the National Association of
Securities Dealers, Inc., a commercial bank or trust company having an office or
correspondent in the United States or otherwise be an "eligible guarantor
institution" within the meaning of Rule 17Ad-15 under the Exchange Act
(collectively, "Eligible Institutions"). If the Letter of Transmittal is signed
by a person other than the registered holder of the Old Notes, the Old Notes
surrendered for exchange must either (i) be endorsed by the registered holder,
with the signature thereon guaranteed by an Eligible Institution or (ii) be
accompanied by a bond power, in satisfactory form as determined by the Issuer in
its sole discretion, duly executed by the registered holder, with the signature
thereon guaranteed by an Eligible Institution. The term "registered holder" as
used herein with respect to the Old Notes means any person in whose name the Old
Notes are registered on the books of the Registrar.
 
     All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of Old Notes tendered for exchange will be
determined by the Issuer in its sole discretion, which determination shall be
final and binding. The Issuer reserves the absolute right to reject any and all
Old Notes not properly tendered and to reject any Old Notes the Issuer's
acceptance of which might, in the judgment of the Issuer or its counsel, be
unlawful. The Issuer also reserves the absolute right to waive any defects or
irregularities or
 
                                       25
<PAGE>   33
 
   
conditions of the applicable Exchange Offer as to particular Old Notes either
before or after the Expiration Date (including the right to waive the
ineligibility of any holder who seeks to tender Old Notes in such Exchange
Offer). The interpretation of the terms and conditions of the Exchange Offers
(including the Letter of Transmittal and the instructions thereto) by the Issuer
shall be final and binding on all parties. Unless waived, any defects or
irregularities in connection with tenders of Old Notes for exchange must be
cured within such period of time as the Issuer shall determine. The Issuer will
use reasonable efforts to give notification of defects or irregularities with
respect to tenders of Old Notes for exchange but shall not incur any liability
for failure to give such notification. Tenders of the Old Notes will not be
deemed to have been made until such irregularities have been cured or waived.
    
 
     If any Letter of Transmittal, endorsement, bond power, power of attorney or
any other document required by the Letter of Transmittal is signed by a trustee,
executor, corporation or other person acting in a fiduciary or representative
capacity, such person should so indicate when signing, and, unless waived by the
Issuer, proper evidence satisfactory to the Issuer, in its sole discretion, of
such person's authority to so act must be submitted.
 
   
     Any beneficial owner of the Old Notes (a "Beneficial Owner") whose Old
Notes are registered in the name of a broker, dealer, commercial bank, trust
company or other nominee and who wishes to tender Old Notes in the applicable
Exchange Offer should contact such registered holder promptly and instruct such
registered holder to tender on such Beneficial Owner's behalf. If such
Beneficial Owner wishes to tender directly, such Beneficial Owner must, prior to
completing and executing the Letter of Transmittal and tendering Old Notes, make
appropriate arrangements to register ownership of the Old Notes in such
Beneficial Owner's name. Beneficial Owners should be aware that the transfer of
registered ownership may take considerable time.
    
 
   
     By tendering, each registered holder will represent to the Issuer that,
among other things, (i) the New Notes to be acquired in connection with the
applicable Exchange Offer by the holder and each Beneficial Owner of the Old
Notes are being acquired by the holder and each Beneficial Owner in the ordinary
course of business of the holder and each Beneficial Owner, (ii) the holder and
each Beneficial Owner are not participating, do not intend to participate, and
have no arrangement or understanding with any person to participate, in the
distribution of the New Notes, (iii) the holder and each Beneficial Owner
acknowledge and agree that any person participating in such Exchange Offer for
the purpose of distributing the New Notes must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with a
secondary resale transaction of the New Notes acquired by such person and cannot
rely on the position of the staff of the Commission set forth in no-action
letters that are discussed herein under "Resales of New Notes," (iv) that if the
holder is a broker-dealer that acquired Old Notes as a result of market making
or other trading activities, it will deliver a prospectus in connection with any
resale of New Notes acquired in such Exchange Offer, (v) the holder and each
Beneficial Owner understand that a secondary resale transaction described in
clause (iii) above should be covered by an effective registration statement
containing the selling security holder information required by item 507 of
Regulation S-K of the Commission, and (vi) neither the holder nor any Beneficial
Owner is an "affiliate," as defined under Rule 405 of the Securities Act, of the
Issuer except as otherwise disclosed to the Issuer in writing. In connection
with a book-entry transfer, each participant will confirm that it makes the
representations and warranties contained in the Letter of Transmittal.
    
 
GUARANTEED DELIVERY PROCEDURES
 
   
     Holders who wish to tender their Old Notes and (i) whose Old Notes are not
immediately available or (ii) who cannot deliver their Old Notes or any other
documents required by the Letter of Transmittal to the Exchange Agent prior to
the Expiration Date (or complete the procedure for book-entry transfer on a
timely basis), may tender their Old Notes according to the guaranteed delivery
procedures set forth in the Letter of Transmittal. Pursuant to such procedures:
(i) such tender must be made by or through an Eligible Institution and a Notice
of Guaranteed Delivery (as defined in the Letter of Transmittal) must be signed
by such Holder; (ii) on or prior to the Expiration Date, the Exchange Agent must
have received from the Holder and the Eligible Institution a properly completed
and duly executed Notice of Guaranteed Delivery (by facsimile transmission, mail
or hand delivery) setting forth the name and address of the Holder, the
certificate number
    
                                       26
<PAGE>   34
 
or numbers of the tendered Old Notes, and the principal amount of tendered Old
Notes, stating that the tender is being made thereby and guaranteeing that,
within five New York Stock Exchange trading days after the date of delivery of
the Notice of Guaranteed Delivery, the tendered Old Notes, a duly executed
Letter of Transmittal and any other required documents will be deposited by the
Eligible Institution with the Exchange Agent; and (iii) such properly completed
and executed documents required by the Letter of Transmittal and the tendered
Old Notes in proper form for transfer (or confirmation of a book-entry transfer
of such Old Notes into the Exchange Agent's account at DTC) must be received by
the Exchange Agent within five New York Stock Exchange trading days after the
Expiration Date. Any Holder who wishes to tender Old Notes pursuant to the
guaranteed delivery procedures described above must ensure that the Exchange
Agent receives the Notice of Guaranteed Delivery and Letter of Transmittal
relating to such Old Notes prior to 5:00 p.m., New York City time, on the
Expiration Date. DTC participants may also submit the Notice of Guaranteed
Delivery through ATOP.
 
ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF NEW NOTES
 
   
     Upon satisfaction or waiver of all the conditions to an Exchange Offer, the
Issuer will accept any and all Old Notes that are properly tendered in such
Exchange Offers prior to 5:00 p.m., New York City time, on the Expiration Date
with respect to such Exchange Offer. The New Notes issued pursuant to an
Exchange Offer will be delivered promptly after acceptance of the Old Notes. For
purposes of the Exchange Offers, the Issuer shall be deemed to have accepted
validly tendered Old Notes, when, as, and if the Issuer has given oral or
written notice thereof to the Exchange Agent.
    
 
   
     In all cases, issuances of New Notes for Old Notes that are accepted for
exchange pursuant to the Exchange Offers will be made only after timely receipt
by the Exchange Agent of such Old Notes, a properly completed and duly executed
Letter of Transmittal and all other required documents (or of confirmation of a
book-entry transfer of such Old Notes into the Exchange Agent's account at DTC);
provided, however, that the Issuer reserves the absolute right to waive any
defects or irregularities in the tender or conditions of the Exchange Offers. If
any tendered Old Notes are not accepted for any reason, such unaccepted Old
Notes will be returned without expense to the tendering Holder thereof as
promptly as practicable after the expiration or termination of the Exchange
Offers.
    
 
WITHDRAWAL RIGHTS
 
   
     Tenders of the Old Notes may be withdrawn by delivery of a written notice
(or for DTC participants, transmission of notice through ATOP) to the Exchange
Agent, at its address set forth on the back cover page of this Prospectus, at
any time prior to 5:00 p.m., New York City time, on the applicable Expiration
Date. Any such notice of withdrawal must (i) specify the name of the person
having deposited the Old Notes to be withdrawn (the "Depositor"), (ii) identify
the Old Notes to be withdrawn (including the certificate number or numbers and
principal amount of such Old Notes, as applicable), (iii) be signed by the
Holder in the same manner as the original signature on the Letter of Transmittal
by which such Old Notes were tendered (including any required signature
guarantees) or be accompanied by a bond power in the name of the person
withdrawing the tender, in satisfactory form as determined by the Issuer in its
sole discretion, duly executed by the registered holder, with the signature
thereon guaranteed by an Eligible Institution together with the other documents
required upon transfer by the Indenture, and (iv) specify the name in which such
Old Notes are to be re-registered, if different from the Depositor, pursuant to
such documents of transfer. Any questions as to the validity, form and
eligibility (including time of receipt) of such notices will be determined by
the Issuer, in its sole discretion. The Old Notes so withdrawn will be deemed
not to have been validly tendered for exchange for purposes of the applicable
Exchange Offer. Any Old Notes which have been tendered for exchange but which
are withdrawn will be returned to the Holder thereof without cost to such Holder
as soon as practicable after withdrawal. Properly withdrawn Old Notes may be
retendered by following one of the procedures described under "The Exchange
Offers -- Procedure for Tendering Old Notes" at any time on or prior to the
Expiration Date.

THE EXCHANGE AGENT; ASSISTANCE
 
     First Trust National Association is the Exchange Agent. All tendered Old
Notes, executed Letters of Transmittal and other related documents should be
directed to the Exchange Agent. Questions and requests for assistance and
requests for additional copies of the Prospectus, the Letter of Transmittal and
other related documents should be addressed to the Exchange Agent as follows:

                      Attn: Specialized Finance Department
 
FEES AND EXPENSES
 
   
     All expenses incident to the Issuer's consummation of the Exchange Offers
and compliance with the 1997 Notes Registration Rights Agreement and the 1998
Notes Registration Rights Agreement, as the case may be, will be borne by the
Issuer, including, without limitation: (i) all applicable Securities and
Exchange Commission, stock exchange or National Association of Securities
Dealers, Inc. ("NASD") registration and filing fees; (ii) all fees and expenses
incurred in connection with compliance with state securities or blue sky laws
(including reasonable fees and disbursements of one counsel for holders that are
Initial Purchasers in connection with blue sky qualifications of any of the New
Notes) and compliance with the rules of the NASD; (iii) all applicable expenses
incurred by the Issuer in preparing or assisting in preparing, word processing,
printing and distributing any registration statement, any prospectus and any
amendments or supplements thereto, and in preparing or assisting in preparing
any other documents relating to the performance of and compliance with the 1997
Notes Registration Rights Agreement or the 1998 Notes Registration Rights
Agreement, as the case may be, (iv) all rating agency fees, if any; and (v) the
fees and disbursements of counsel for the Issuer.
    
 
   
     The Issuer has not retained any dealer-manager in connection with the
Exchange Offers and will not make any payments to brokers, dealers of others
soliciting acceptance of the Exchange Offers. The Issuer, however, will pay the
Exchange Agent reasonable and customary fees for its services and will reimburse
it for its reasonable out-of-pocket expenses in connection therewith.
    
 
   
     The Company will pay all transfer taxes, if any, applicable to the exchange
of Old Notes pursuant to the Exchange Offers. If, however, a transfer tax is
imposed for any reason other than the exchange of Old Notes pursuant to the
Exchange Offers, then the amount of any such transfer taxes (whether imposed on
the registered holder or any other persons) will be payable by the tendering
holder. If satisfactory evidence of payment of such taxes or exemption is not
submitted with the Letter of Transmittal, the amount of such transfer taxes will
be billed directly to such tendering holder.
    
 
                                       28
<PAGE>   36
 
ACCOUNTING TREATMENT
 
   
     The New Notes will be recorded at the same carrying value as the Old Notes,
as reflected in the Issuer's accounting records on the date of the exchange.
Accordingly, no gain or loss will be recognized by the Issuer for accounting
purposes. The expenses of the Exchange Offers will be amortized over the term of
the respective New Notes.
    
 
RESALES OF THE NEW NOTES
 
   
     Based on the position of the staff of the Commission as set forth in
certain interpretive letters issued to third parties in other transactions, the
Issuer believes that the New Notes issued pursuant to the Exchange Offers to any
holder of Old Notes in exchange for Old Notes may be offered for resale, resold
and otherwise transferred by such holder (other than (i) a broker-dealer who
purchased Old Notes directly from the Issuer for resale pursuant to Rule 144A
under the Securities Act or any other available exemption under the Securities
Act, or (ii) a person that is an affiliate of the Issuer within the meaning of
Rule 405 under the Securities Act) without further compliance with the
registration and prospectus delivery provisions of the Securities Act, provided
that such holder is acquiring the New Notes in the ordinary course of business
and is not participating, and has no arrangement or understanding with any
person to participate, in the distribution of the New Notes. However, the Issuer
has not sought its own interpretive letter and there can be no assurance that
the Commission would make a similar determination with respect to the Exchange
Offers. The Issuer and holders of Old Notes are not entitled to rely on
interpretive advice provided by the staff of other persons, which advice was
based on the facts and conditions represented in such letters. However, the
Exchange Offers are being conducted in a manner intended to be consistent with
the facts and conditions represented in such letters. If any holder acquires New
Notes in an Exchange Offer for the purpose of distributing or participating in a
distribution of the New Notes, such holder cannot rely on the position of the
staff of the Commission enunciated in Morgan Stanley & Co. Incorporated
(available June 5, 1991) and Exxon Capital Holdings Corporation (available May
13, 1989), or interpreted in the Commission's letter to Shearman and Sterling
(available July 2, 1993), or similar no-action or interpretive letters and must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with a secondary resale transaction, unless an
exemption from registration is otherwise available. Each broker-dealer that
receives New Notes for its own account in exchange for Old Notes, where such Old
Notes were acquired by such broker-dealer as a result of market making or other
trading activities, must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes. See "Plan of Distribution."
    
 
   
     It is expected that the New Notes will be freely transferable by the
holders thereof, subject to the limitations described in the immediately
preceding paragraph. Sales of New Notes acquired in the Exchange Offers by
holders who are "affiliates" of the Issuer within the meaning of the Securities
Act will be subject to certain limitations on resale under Rule 144 of the
Securities Act (if applicable). Such persons will only be entitled to sell New
Notes in compliance with the volume limitations set forth in Rule 144, and sales
of New Notes by affiliates will be subject to certain Rule 144 requirements as
to the manner of sale, notice and the availability of current public information
regarding the Issuer. The foregoing is a summary only of Rule 144 as it may
apply to affiliates of the Issuer. Any such persons must consult their own legal
counsel for advice as to any restrictions that might apply to the resale of
their New Notes.
    
 
                                USE OF PROCEEDS
 
   
     There will be no cash proceeds payable to the Company from the issuance of
the New Notes pursuant to the Exchange Offers.
    
 
   
     The Exchange Offers are intended to satisfy certain of the Company's
obligations under the 1997 Notes Registration Rights Agreement and the 1998
Notes Registration Rights Agreement. In consideration for issuing the New Notes
as contemplated in this Prospectus, the Issuer will receive in exchange Old
Notes in like principal amount, the form and terms of which are the same in all
material respects as the form and terms of the New Notes except that the New
Notes will be registered under the Securities Act and hence do not include
certain rights to registration thereunder. The Old Notes surrendered in exchange
for New Notes will
    
                                       29
<PAGE>   37
 
be retired and canceled and cannot be reissued. Accordingly, issuance of the New
Notes will not result in any increase in the indebtedness of the Company.
 
   
     Net proceeds from the Initial 1997 Notes Offering (after deducting the
Initial 1997 Notes Purchasers' discount and expenses payable by the Issuer) were
approximately $144.8 million. Approximately $46.6 million of such net proceeds
were deposited in an escrow account for the benefit of the holders of the Old
1997 Notes to fund when due the first five scheduled interest payments on the
Old 1997 Notes. Amounts on deposit in the escrow account are held in cash or
used to purchase U.S. Government Securities, and, upon consummation of the
applicable Exchange Offer, will continue to be held for the benefit of the
holders of the New 1997 Notes to fund the remaining scheduled interest payments
on the New Notes through December 15, 1999. The balance of the net proceeds from
the Initial 1997 Notes Offering have been and continue to be used to further the
Company's ISP acquisition and investment strategy, to continue the development
and implementation of the national backbone, customer care center, network
operations center and billing and accounting services, and to support the
Company's general working capital purposes. Pending application of the proceeds
as described above, the Company has invested the net proceeds of the issuance of
the Old 1997 Notes in short-term, interest-bearing, investment-grade securities.
    
 
   
     Net proceeds from the Initial 1998 Notes Offering (after deducting the
Initial 1998 Notes Purchasers' discount and expenses payable by the Issuer) were
approximately $169.8 million. The net proceeds from the Initial 1998 Notes
Offering have been and continue to be used to further the Company's ISP
acquisition and investment strategy, to continue the development and
implementation of the national backbone, customer care center, network
operations center and billing and accounting services, and to support the
Company's general working capital purposes. Pending application of the proceeds
as described above, the Company has invested the net proceeds of the issuance of
the Old 1998 Notes in short-term, interest-bearing, investment-grade securities.
    
 
                                DIVIDEND POLICY
 
   
     The Company has never declared or paid any dividends on its Common Stock
and does not expect to pay dividends in the foreseeable future. The Company's
current policy is to retain all of its earnings to finance future growth and
acquisitions. Furthermore, the terms of the 1997 Indenture, the 1998 Indenture
and the Bank Facility place limitations on the Company's ability to pay
dividends. Future dividends, if any, will be at the discretion of the Board and
will depend upon, among other things, the Company's operations, capital
requirements and surplus, general financial condition, contractual restrictions
and such other factors as the Board may deem relevant. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

                             (dollars in thousands)
 
   
     The following table sets forth at December 31, 1997 (i) the actual
capitalization of the Company, (ii) the pro forma capitalization adjusted for
the Completed and Proposed Acquisitions and Buyouts, and the conversion of all
the outstanding Preferred Stock into Common Stock upon the completion of the
proposed IPO, and (iii) the pro forma capitalization adjusted to reflect the
proposed IPO, the proceeds from the 1998 Notes, the Refinancing, and the NTT
Investment. This table should be read in conjunction with the Selected
Consolidated Financial Data, the Unaudited Pro Forma Condensed Combined
Financial Statements and the Historical Consolidated Financial Statements and
notes thereto included elsewhere in this Prospectus.

          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 includes a number of ISPs acquired at various
times. See "Unaudited Pro Forma Condensed Combined Financial Statements" for the
basis of presentation and those business acquisitions included therein.
Investments in ISP affiliates in which Verio acquires a minority interest are
accounted for at cost. Investments in ISP affiliates in which Verio acquires a
majority interest through the acquisition of net assets, common stock or
convertible preferred stock, and exercises significant control over the
operations are accounted for using the purchase method of accounting and,
accordingly, the financial results of these ISPs have been consolidated with
those of the Company. Certain statements set forth below constitute
"forward-looking statements" within the meaning of the Reform Act. The safe
harbor provisions provided in Section 27A of the Securities Act and Section 21E
of the Exchange Act do not apply to forward-looking statements made in
connection with an initial public offering. Such forward-looking statements
involve known and unknown risks, uncertainties and other factors that may cause
the actual results, performance or achievements of the Company, or industry
results, to be materially different from any future results, performance or
achievements expressed or implied by such forward-looking statements. Given
these uncertainties, prospective investors are cautioned not to place undue
reliance on such forward-looking statements. See "Risk Factors -- Forward-
Looking Statements."
    
 
OVERVIEW
 
   
     Verio is a leading national provider of Internet connectivity and enhanced
Internet services to small and medium sized businesses. Since its inception in
March 1996, the Company has rapidly established a national presence through the
acquisition, integration, and growth of local ISPs with a business customer
focus. Verio believes that small and medium sized businesses represent an
attractive target market for the provision of Internet services due to this
market's low current penetration levels and customer churn, and the expanding
Internet needs of these businesses. The Company believes it has a unique
competitive advantage in serving small and medium sized business customers
through the combination of the technical competency, hands-on support and
entrepreneurial culture of locally based ISPs with the quality and economic
efficiency of Verio's national network, operational infrastructure and financial
strength. Verio has quickly built critical mass by acquiring the stock or assets
of, or making significant investments in, over 30 ISPs that provide a
comprehensive range of Internet connectivity and enhanced products and services
to over 80,000 customer accounts in 33 of the top 50 MSAs in the country, with
combined revenues of approximately $23.2 million for the three months ended
December 31, 1997.
    
 
   
     From March 1996 through September 1997, Verio's strategy was to acquire 51%
to 100% of a large regional ISP, and a minority interest in smaller ISPs within
each region. Verio now seeks to acquire 100% of new ISPs, and is in the process
of bringing its ownership interest in its existing ISPs to 100%. Upon achieving
100% ownership of its ISPs in a region, Verio then consolidates the management
teams, network operations, and marketing efforts within that region. While some
one-time costs are incurred in these consolidation efforts, Verio believes that
the combined organizations will be able to increase revenues faster and more
cost effectively. In addition, 100% ownership facilitates the introduction of
the Verio brand name, a suite of nationwide product offerings, and the
transition of all ISPs onto Verio's national network and financial systems.
    
 
   
     In conjunction with the consolidation of its regional operations, as of
December 31, 1997, the Company had completed the Buyout of four of its initially
non-wholly owned ISPs. Since then, the Company has completed eight additional
Buyouts and intends to complete the Buyouts of the four remaining ISPs in which
it did not initially acquire 100% ownership during the remainder of 1998. The
Company expects to consummate two of those four remaining Buyouts prior to or
concurrently with the proposed IPO, and considers those two Buyouts to be
probable. Verio has incurred and expects to incur costs of approximately $50.0
million, in the aggregate, in 1998 in connection with the Buyouts, which have
been and will be paid with a combination of cash and preferred stock of Verio.
As a result of its acquisitions, and the limited amount of
    
 
                                       34
<PAGE>   42
 
fixed assets required to operate an ISP, Verio has recorded significant amounts
of goodwill, and expects goodwill to increase significantly during 1998.
 
   
     To fund its acquisitions and operations, Verio has raised approximately
$100.0 million of equity capital primarily from venture capital funds and Brooks
(recently acquired by WorldCom). It also issued $150.0 million principal amount
of Old 1997 Notes to a group of institutional investors and Brooks, $100.0
million of which remain outstanding following the Refinancing. On March 25,
1998, the Company consummated the sale of $175.0 million principal amount of Old
1998 Notes, a portion of the proceeds of which was used to effect the
Refinancing. See "-- Liquidity and Capital Resources" and "Certain
Transactions."
    
 
RESULTS OF OPERATIONS
 
  REVENUE
 
     The Company derives the majority of its revenues from business customers
who purchase Internet connections and enhanced services such as Web hosting.
Verio's ISP affiliates offer a broad range of connectivity options to their
customers including dedicated, dial-up, ISDN, frame relay and point-to-point
connections. Dedicated customers typically sign a contract for one to three
years of service that provides for fixed, recurring monthly service charges, and
pay a one-time setup fee. These charges vary depending on the type of service,
the length of the contract, and local market conditions. Dial-up customers also
typically pay a one-time setup fee and recurring monthly service charges. Fees
and service charges for enhanced services vary from product to product. For
example, Web hosting customers pay a one-time setup fee and fixed monthly
service charges that vary depending on the amount of disk space and bandwidth
required. Additional sources of revenue include e-commerce, virtual private
networks, security services, co-location services, consulting and the sales of
equipment and customer circuits. Revenue related to Internet connectivity and
enhanced services is recognized as the services are provided. Amounts billed
relating to future periods are recorded as deferred revenue and amortized
monthly as services are rendered.
 
     Currently, connectivity services provide a majority of total revenues.
However, revenues from enhanced services, especially Web hosting, are expected
to represent an increasing percentage of total revenues in future periods.
Revenue from business customers currently represents more than 80% of total
revenues and is projected to increase as a percent of total revenues. In
addition to the growth that the Company is achieving through acquisitions,
revenues are also expected to increase due to the internal growth of
consolidated ISPs. For ISPs consolidated for the entire fiscal year of 1997,
revenue increased an average of 16% quarter-over-quarter for the three quarters
ended December 31, 1997.
 
  Year Ended December 31, 1997 Compared to the Period from Inception to December
31, 1996
 
   
     Total consolidated revenues were $35.7 million for the year ended December
31, 1997, compared to $2.4 million for the period from inception (March 1, 1996)
to December 31, 1996 (the "1996 Period"). Internet connectivity represented 66%
and 95% of total revenue for the year ended December 31, 1997 and the 1996
Period, respectively, with the balance derived from enhanced services and other,
which include Web hosting, consulting, sales of equipment and customer circuits.
The increase in dedicated and dial-up revenues and enhanced services and other
revenues for the year ended December 31, 1997 compared to the 1996 Period was
primarily due to the acquisitions of ISPs subsequent to December 31, 1996 and
the longer period covered. Twenty-two ISPs were included in the consolidated
financial statements at December 31, 1997, three of which were included in the
consolidated financial statements for the entire year ended December 31, 1997.
Three ISPs were included in the consolidated financial statements at December
31, 1996. The increase in enhanced services as a percentage of total revenue is
due to a change in the revenue mix resulting from acquisitions and increased
sales of enhanced services.
    
 
  COSTS AND EXPENSES
 
   
     Internet services operating costs consist primarily of local
telecommunication expense, Internet access expense and the cost of equipment and
customer circuits sold. Local telecommunications expense represents the cost of
transporting data between the Company's POPs and a transit provider, or various
Internet access points. Internet access expense includes the cost incurred by
the Company to transport its Internet traffic and for its national network. In
some instances the Company also will pay for the local telecommunications
line(s)
    
 
                                       35
<PAGE>   43
 
   
from the customer's location to one of the POPs. As of December 31, 1997, 25 ISP
affiliates were utilizing the Verio national network for their Internet access
and paying Verio for these network services based on their bandwidth
requirements. The Company recently signed a long-term long haul capacity
agreement with Qwest in order to reduce the per unit costs of such services.
There will not be a significant effect on the results for 1998 from this
agreement due to the time required to convert from existing circuits; however,
the Company expects that the pricing advantages provided by this agreement will
substantially reduce the cost of these services in future years. Additionally,
the Company has the right to fund its minimum commitment, which would allow the
capitalization of costs (to the extent prepaid) under this contract. Such
capitalized costs would be amortized to operations over the term of the
agreement. The amount of the prepayment currently would be approximately $60.0
million.
    
 
     Selling, general and administrative and other expenses consist primarily of
salaries and related employment expenses, consulting, travel and entertainment,
rent, and utilities. Depreciation is provided over the estimated useful lives of
the assets ranging from 3 to 5 years using the straight-line method. The excess
of cost over the fair value of net assets acquired, or goodwill, is amortized
using the straight-line method over a ten-year period.
 
  Year Ended December 31, 1997 Compared to the Period from Inception to December
31, 1996
 
   
     Internet services operating costs were 45% and 41% of total revenues for
the year ended December 31, 1997 and the 1996 Period, respectively. Selling,
general and administrative and other expenses were 138% and 296% of revenues for
the year ended December 31, 1997 and the 1996 Period, respectively. The Company
expects Internet services operating costs to increase in absolute dollars but to
decrease as a percentage of total revenues over time as additional ISP
affiliates are added onto Verio's national network, as enhanced services become
a larger percentage of total revenues, and as the Qwest agreement is
implemented. The Company expects selling, general and administrative expenses to
continue to increase in absolute dollars but to decrease as a percentage of
total revenues as the Company acquires additional ISPs, allowing it to spread
its corporate overhead over a larger revenue base, as its scaleable systems
reduce the incremental costs of additional revenues, as sales force productivity
increases with experience, and as indirect selling channels are expanded. The
anticipated increases in absolute dollar terms will be primarily due to
increased personnel resulting from acquisitions, and additional expenditures in
sales and marketing. Depreciation and goodwill amortization are expected to
continue to increase significantly as a result of the Company's acquisition and
investment strategies. Also, the Company will continue to have non-recurring
expenses related to its strategy of acquiring and regionalizing groups of ISPs.
The significant increase in Internet services operating costs and expenses and
in selling, general and administrative and other expenses, for the year ended
December 31, 1997 compared to the 1996 Period was primarily due to the
acquisitions of ISPs subsequent to December 31, 1996 and the longer period
covered. Twenty-two ISPs were included in the consolidated financial statements
at December 31, 1997, three of which were included in the consolidated financial
statements for the entire year ended December 31, 1997. Three ISPs were included
in the consolidated financial statements at December 31, 1996.
    
 
  OTHER EXPENSES
 
   
     During the year ended December 31, 1997, the Company recognized equity in
losses of affiliates in the amount of $1,958,000, representing losses of those
affiliates in excess of the equity of the common shareholders of the affiliates.
See Note 1 to the Consolidated Financial Statements of the Company.
    
 
   
     Interest expense increased from $115,000 in the 1996 Period to $11.8
million for the year ended December 31, 1997 primarily as a result of the
completion of the $150.0 million placement of the Old 1997 Notes on June 24,
1997. Interest expense is expected to increase in 1998, reflecting a full year's
interest on the 1997 Notes and interest due on the 1998 Notes.
    
 
  INCOME TAXES
 
     As of December 31, 1997, the Company had a net operating loss carryforward
for federal income tax purposes of approximately $49.9 million which is
available to offset future federal taxable income, if any, through 2011. The
utilization of a portion of the net operating loss carryforwards may be limited
under Section 382 of the Internal Revenue Code. No tax benefit for such losses
has been recorded by the Company in 1996 or 1997 due to uncertainties regarding
the utilization of the loss carryforward.

     The Company's operating results have fluctuated in the past and may in the
future fluctuate significantly depending upon a variety of factors, including
the incurrence of capital costs and costs associated with the Buyouts and the
introduction of value-added enhanced services and new services by the Company.
Additional factors that may contribute to variability of operating results
include: the pricing and mix of services offered by the Company; customer
retention rate; changes in pricing policies and product offerings by the
Company's competitors; growth in demand for network and Internet access
services; one-time costs associated with regional consolidation; and general
telecommunications services' performance and availability. The Company also has
experienced seasonal variation in Internet use and, therefore, revenue streams
may fluctuate accordingly. As a result, variations in the timing and amounts of
revenues could have a material adverse effect on the Company's quarterly
operating results. Due to the foregoing factors, the Company believes that
period-to-period comparisons of its operating results are not necessarily
meaningful and that such comparisons cannot be relied upon as indicators of
future performance.
    
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     The Company's business has required and will continue to require
substantial capital for investments in ISP affiliates, the acquisition of
additional ISPs, the Buyouts of remaining interests in ISPs, capital
expenditures for expansion of services, operating losses and working capital.

     Net cash used by operating activities was $35.3 million during the year
ended December 31, 1997, which includes a decrease of $88,000 in working
capital. Net cash used by investing activities was $120.3 million during the
year ended December 31, 1997, which includes the investment of restricted cash
totalling $46.6 million from the proceeds of the Old 1997 Notes, and
approximately $64.0 million for acquisitions. Net cash provided by financing
activities was $161.8 million during the year ended December 31, 1997, primarily
from the sale of 2,500,000 shares of Series C Preferred Stock for gross proceeds
of approximately $20.0 million and issuance of the Old 1997 Notes for gross
proceeds of approximately $150.0 million.
    
 
     Since inception, the Company has financed itself primarily through the
private sale of Preferred Stock and debt and, to a lesser extent, Common Stock.
In 1996, the Company raised approximately $79.2 million (gross) through the
issuance of Common Stock, Series A Preferred Stock and Series B Preferred Stock.
In June 1996, the Company sold 6,033,333 shares of Series A Preferred Stock and
in December 1996, the Company sold 10,000,000 shares of Series B Preferred Stock
for gross proceeds of approximately $18.1 million and approximately $60.0
million, respectively. During the course of 1996, 1,090,000 shares of Common
Stock were sold for gross proceeds of approximately $1.1 million. In 1997, an
additional 164,533 shares of Common Stock were issued for approximately
$508,000. In May 1997, the Company completed the sale of 2,500,000 shares of
Series C Preferred Stock for gross proceeds of approximately $20.0 million. In
December 1997, the Company issued 680,000 shares of Series D-1 Preferred Stock
to fund a portion of the acquisition cost of one affiliate. Each share of
Preferred Stock is convertible into Common Stock on a one-for-one basis.
 
   
     On June 24, 1997, the Company completed the placement of $150.0 million
principal amount of the Old 1997 Notes and attached warrants (the "Warrants").
One hundred fifty thousand units were issued, each consisting of $1,000
principal amount of the Old 1997 Notes and eight Warrants, with each Warrant
entitling the holder thereof to purchase 1.76 shares of the Company's Common
Stock at a price of $.01 per share, for a total of 2,112,480 shares of Common
Stock. The Warrants and the Old 1997 Notes were separated on December 15, 1997.
The 1997 Notes mature on June 15, 2004. Interest on the 1997 Notes, at the
annual rate of 13 1/2%, is payable semi-annually in arrears on June 15 and
December 15 of each year. Concurrent with the completion of the sale of the Old
1997 Notes, the Company was required to deposit funds into an escrow account in
an amount that together with interest would be sufficient to fund the first five
interest payments on the 1997 Notes. Upon consummation of the sale of the Old
1998 Notes and the Refinancing, that portion of the escrowed amount attributable
to the principal amount of the Old 1997 Notes refinanced was released to the
Company. The 1997 Notes are redeemable at the option of the Company commencing
June 15, 2002. The 1997 Notes are senior unsecured obligations of the Company
ranking pari passu in right of payment with all existing and future unsecured
and senior indebtedness. The 1997 Notes impose significant limitations on the
Company's ability to incur additional indebtedness unless the Company's
Consolidated Pro Forma Interest Coverage Ratio (as defined) is greater than or
equal to 1.8 to 1.0 prior to June 30, 1999, or 2.5 to 1.0 on or after that date.
The Company is also limited in its ability to pay dividends or make Restricted
Payments (as defined), to engage in businesses other than the internet service
business, and to place liens on its assets for the benefit of persons other than
the bondholders, among other restrictions. If a Change of Control (as defined in
the 1997 Indenture) occurs, the Company is required to make an offer to purchase
all of the Old 1997 Notes then outstanding at a price equal to 101% of the
principal amount, plus accrued and unpaid interest.
    
 
   
     On February 27, 1998, Verio filed a registration statement on Form S-1 with
respect to the proposed IPO. No assurance can be given that the IPO will be
consummated or, if consummated, that the amount of proceeds received or amount
of Common Stock sold by the Company will be in the amounts currently
contemplated.
    
 
   
     On March 25, 1998, the Company completed the placement of $175.0 million
principal amount of the Old 1998 Notes. The 1998 Notes mature on April 1, 2005.
Interest on the 1998 Notes, at the annual rate of 10 3/8%, is payable
semi-annually in arrears on April 1 and October 1 of each year, commencing
October 1, 1998. The 1998 Notes are redeemable at the option of the Company
commencing April 1, 2002. The 1998 Notes are senior unsecured obligations of the
Company ranking pari passu in right of payment with all existing and future
unsecured and senior indebtedness. The form and terms of the New 1998 Notes will
be identical in all material respects to the form and terms of the Old 1998
Notes, except that the New 1998 Notes will be registered under the Securities
Act, and therefore will not be subject to certain transfer restrictions and
    
                                       38

registration rights provisions applicable to the Old 1998 Notes. The Company
used approximately $54.5 million of the proceeds from the issuance of the Old
1998 Notes to effect the Refinancing. As a result of the Refinancing, the
Company was refunded approximately $13.3 million from the escrow account for the
1997 Notes, of which approximately $1.9 million was used to pay accrued and
unpaid interest on the $50.0 million principal amount of Old 1997 Notes
repurchased from Brooks.
    
 
   
     On April 6, 1998, Verio entered into the Bank Facility with a group of
commercial lending institutions that committed to provide a $57.5 million
revolving credit facility secured by the stock of the ISPs that Verio owns
currently or may own in the future and the Capacity Agreement (as defined). See
"Business -- Verio National Network." The Chase Manhattan Bank serves as agent
for the Bank Facility. The Bank Facility requires no payments of principal until
its maturity on December 31, 1999. The terms of the Bank Facility provide for
borrowings at LIBOR + 3%, with a 1% decrease in that rate if the Company has
completed a public equity offering of $50.0 million or more. If the Company has
not completed such an offering by December 31, 1998, or by June 30, 1999, there
will be a 2% increase in the rate on each such date. There is a commitment fee
of  1/2% per annum on the undrawn amount of the Bank Facility and a one-time fee
of  1/2% on any amounts drawn. The last $3.0 million of the Bank Facility cannot
be drawn except for the payment of interest.
    
 
   
     The Bank Facility sets forth covenants restricting, among other things, the
Company's ability to borrow, to guarantee the debt of others, and to make
borrowings at the subsidiary level. The Company is also limited in its ability
to enter into transactions with affiliates, create liens on its assets, and make
certain investments. In particular, Indebtedness (less cash) may not exceed 2.35
times annualized pro forma revenues for the most recent fiscal quarter.
Dividends and certain types of investments are prohibited, as are liens incurred
for borrowed money. Borrowings under the Bank Facility would be required to be
paid down with the proceeds of new Indebtedness (as defined), certain asset
sales, Excess Cash Flow (as defined), or the net proceeds from insurance claims.
    
 
   
     On April 7, 1998, the Company entered into agreements establishing a
strategic relationship with NTT pursuant to which the Company agreed to sell to
NTT, concurrently with and conditioned upon consummation of the proposed IPO, a
number of shares of Common Stock equal to the lesser of (i) 12.5% of the total
number of outstanding shares of Common Stock, on a fully diluted and fully
converted basis (taking into account the proposed IPO and the NTT Investment) or
(ii) the quotient of $100.0 million divided by 96.75% of the price to public in
the proposed IPO. See "Business -- NTT Strategic Relationship."
    
 
     As of December 31, 1997, the Company had approximately $72.6 million in
cash and cash equivalents (excluding restricted cash). The Company's business
plan currently anticipates investments of approximately $175.0 million in 1998
for capital expenditures, ISP acquisitions, operating losses and working
capital. The Company's anticipated expenditures are inherently uncertain and
will vary widely based on many factors including the operating performance and
working capital requirements of the Company and its existing ISP affiliates, the
number and size of additional ISPs acquired or invested in by the Company, the
cost of such additional acquisitions and investments, the operating performance
and working capital requirements of the Company's ISP affiliates including any
additional ISP affiliates and capital expenditure requirements of the Company
and any existing or additional ISPs. Accordingly, the Company may need
significant amounts in excess of its plan, and no assurances can be given as the
actual amounts of the Company's expenditures and additional capital
requirements.
 
   
     The Company expects to meet its capital needs with cash on hand, proceeds
from the sale, or issuance of capital stock, credit facilities (including the
Bank Facility), and lease financing. There can be no assurance that the Company
will have sufficient resources to fund its investment programs, particularly if
operating losses continue to increase. EBITDA decreased from negative $5.6
million in the 1996 Period to negative $29.7 million in 1997 despite an increase
in revenues from $2.4 million to $34.7 million, respectively. The Company
incurred $49.4 million in selling, general and administrative expenses in 1997
as it invested in scaleable systems, hiring and sales training, and network
improvements, that it expects will result in incremental revenue at reduced
incremental costs. The Company will have to increase revenues without a
commensurate increase in costs to generate sufficient cash to enable it to meet
its debt service obligations as described above. There can be no assurance that
the Company will be able to service its indebtedness.

Insufficient funding may require the Company to delay or abandon some of its
planned future expansion or expenditures, which could have a material adverse
effect on the Company's growth and its ability to compete. In addition, the
Company's operating flexibility with respect to certain business activities is
limited by covenants associated with its indebtedness. 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 business activities that
may be in the interest of the Company.

OVERVIEW
 
     Verio is a leading national provider of Internet connectivity and enhanced
Internet services to small and medium sized businesses. Since its inception in
March 1996, the Company has rapidly established a national presence through the
acquisition, integration, and growth of local ISPs with a business customer
focus. Verio believes that small and medium sized businesses represent an
attractive target market for the provision of Internet services due to this
market's low current penetration levels and customer churn rates, and the
expanding Internet needs of these businesses. Because of their limited internal
technical resources, small and medium sized businesses also typically require
hands-on local support and highly reliable turnkey solutions for mission
critical applications. Verio further believes that these needs currently are
underserved by both the national and local ISPs. While national ISPs lack the
local presence to provide customized, hands-on service, local ISPs typically
lack the scale and resources required to provide dedicated, high-capacity
Internet access, around-the-clock support and tailored product offerings at
competitive prices.
 
   
     The Company believes it has a unique competitive advantage in serving small
and medium sized business customers, through the combination of the technical
competency, hands-on support and entrepreneurial culture of locally based ISPs
with the quality and economic efficiency of Verio's national network,
operational infrastructure and financial strength. Verio has quickly built
critical mass by acquiring the stock or assets of, or making significant
investments in, over 30 ISPs that provide a comprehensive range of Internet
connectivity and enhanced products and services to over 80,000 customer accounts
in 33 of the top 50 MSAs in the country, with combined revenues of approximately
$23.2 million for the three months ended December 31, 1997. The Company
integrates and optimizes the operations of its ISPs by consolidating their
operations into regional operating units with centralized regional management,
connecting their local networks to Verio's high-speed, highly reliable national
backbone, and providing them with Verio's integrated national support services.
    
 
   
     Verio believes that a critical factor in the successful implementation of
its business strategy is the quality of its management team and Board of
Directors. The Company's senior management team and Board of Directors have
previously successfully executed similar consolidation strategies and have
considerable experience in the management and growth of recurring revenue-based
telecommunications businesses. Management believes that its experience in the
deployment of similar systems and services in other emerging telecommunications
industries can be leveraged to significantly improve the quality of services
currently available in the Internet service industry.
    
 
INDUSTRY BACKGROUND
 
   
     Internet connectivity and enhanced Internet services represent two of the
fastest growing segments of the telecommunications services market. Total ISP
revenues in the United States are projected to grow from $3.3 billion in 1996 to
$18.3 billion in 2000, according to IDC, an independent company that prepares
market studies relating to the Internet. The availability of Internet
connectivity, advancements in technologies required to navigate the Internet,
and the proliferation of content and applications available over the Internet
have attracted a rapidly growing number of users. Businesses are increasingly
recognizing that the Internet can significantly enhance communications among
geographically distributed offices and employees as well as with customers and
suppliers. In addition, the Internet presents a compelling profit opportunity
for businesses as it enables them to reduce operating costs, access valuable
information and reach new markets. As a result, businesses increasingly are
utilizing the Internet for mission critical applications such as sales, customer
service and project coordination. IDC estimates that U.S. corporate dedicated
access revenues will grow from $1.1 billion in 1996 to $5.6 billion in 2000,
representing a 50% compounded annual growth rate. There can be no assurance that
the bases for these projections or the results generated thereby will be
realized.
    
 
     In addition to Internet connectivity, business customers increasingly are
seeking a variety of enhanced products and applications to take full advantage
of the Internet. For example, a growing number of businesses are implementing
secured virtual private networks ("VPNs") over the Internet as a more economical
option
 
                                       41
<PAGE>   49
 
than dedicated private networks. Technological advances such as increases in
microprocessor speeds, the introduction of innovative software tools and the
development of higher bandwidth data networking technology have led to rapid
innovation and development of enhanced Internet services. The principal enhanced
services being offered by business-oriented ISPs today include Web hosting,
security, e-commerce, virtual private networks (sometimes called "intranets" and
"extranets"), and advanced Internet applications such as voice and fax, video
conferencing and data storage and retrieval solutions. According to IDC,
enhanced services is the fastest growing segment of the Internet services market
and is expected to grow from $126 million in 1996 to over $7 billion in 2000. As
business users of the Internet adopt enhanced services, they also require
additional bandwidth to support their expanded use of the Internet. The Company
expects this trend to continue as high-bandwidth enhanced services continue to
be developed, improve and proliferate and as Internet usage continues to expand.
 
     Industry analysts have reported that small and medium sized businesses
represent a potential market of over seven million customers in the U.S., and
use of the Internet by this market segment is expected to grow substantially
from its current low level of market penetration. IDC predicts that dedicated
connections to the Internet for small and medium sized businesses will grow from
approximately 90,000 in 1996 to just under 800,000 in 2000, representing a 73%
compounded annual growth rate. Small and medium sized businesses generally seek
an ISP with locally based personnel who are readily available to respond
in-person to technical issues, who can assist in developing and implementing the
customer's effective use of the Internet, and with whom they can establish a
stable and long-term relationship. In addition, they are increasingly reliant on
enhanced product offerings that address their specific business needs on a
cost-effective basis, allowing them to compete with larger companies. For
example, IDC estimates Web hosting revenues from small and medium sized
businesses will grow from $84 million in 1996 to over $3.4 billion in 2000,
representing 95% of the total Web hosting market.
 
     The rapid development and growth of the Internet has resulted in a highly
fragmented industry of over 4,000 national and local ISPs in the United States,
with no dominant ISP serving the needs of small and medium sized businesses. The
large national ISPs have primarily focused on the large business or consumer
markets and lack the local presence to provide the customized, hands-on service
required by small and medium sized businesses. The Company believes that
independent local and regional ISPs generally have been more adept at serving
small and medium sized businesses, and that these ISPs are often the source of
innovative Internet products and services. As a result, independent regional and
local ISPs have successfully captured approximately one-half of this market,
despite the substantially greater resources of the national providers. However,
rising costs and increasing demands from business customers are making it more
difficult for the small ISP to meet its customer's demands on a cost-effective
basis. Facing these competitive pressures, Verio believes that independent
regional and local ISPs will continue to be attracted to and benefit from the
consolidation opportunity provided by Verio.
 
THE VERIO SOLUTION
 
     Verio is a leading provider of Internet connectivity and enhanced Internet
services to small and medium sized businesses. The Company's business strategy
of combining national scale with local presence was specifically developed to
serve the needs of this market sector. Verio has taken a leading role in
consolidating the fragmented, independent ISP industry, rapidly establishing its
national presence through the acquisition, integration, and growth of
established, well-regarded regional and local ISPs with a business customer
focus. The Company believes it has a unique competitive advantage in serving
small and medium sized business customers. Verio's combination of national scale
with local presence provides distinct and significant value to these customers,
which the Company expects will result in long-term customer loyalty and an
expanding customer base. Verio intends to enhance this value as it continues to
develop, both internally and through strategic vendor relationships, an
expanding array of enhanced, higher margin product and service offerings to
continue to address the business needs of its customers. The Company further
believes that the small and medium sized business market is more attractive than
the consumer or large business market segments for Internet services, in large
part due to the stability of the customer relationship resulting from the
customer's reliance on its service provider's hands-on technical support and
ability to provide a turnkey Internet solution based on customized products and
services designed for the customer's particular business needs. The
 
                                       42
<PAGE>   50
 
Company's market research indicates that Verio's local presence, providing
around-the-clock, hands-on technical support and tailored Internet service
solutions combined with its high speed, highly reliable national backbone, will
be significant factors in the purchase decision for the small and medium sized
business customer, as well as being a critical factor driving customer loyalty.
 
THE VERIO STRATEGY
 
     The goal of the Company is to be the dominant, full-service national
provider of Internet connectivity and enhanced Internet services to small and
medium sized businesses. Key elements of the Company's strategy in accomplishing
this goal are to: (a) continue its role as the leading consolidator of
independent ISPs by acquiring additional local and regional ISPs focused on the
Company's target market; (b) integrate the operations of its ISPs and capture
operational economies of scale by leveraging its national infrastructure and
support services; (c) develop and offer additional high-margin enhanced services
to increase revenues from existing and future customers; and (d) build customer
loyalty and gain market share by expanding the Company's local technical,
distribution and service capabilities and establishing national Verio brand name
recognition.
 
   
     Continue Consolidation Through Acquisitions. Verio has rapidly established
a national presence and critical customer mass by acquiring the stock or assets
of, or making significant investments in, established, well-regarded independent
ISPs in selected regions throughout the U.S. The Company intends to continue its
consolidation strategy, acquiring additional business-focused ISPs to deepen and
broaden its market presence and to expand its strength in targeted product areas
such as Web hosting. Given the increasing competitive pressures facing the
independent local and regional ISPs, Verio believes that these ISPs will
continue to be attracted to and benefit from the consolidation opportunity
provided by Verio. As part of its integration strategy, the Company now seeks to
acquire 100% of new ISP affiliates and expects to effect the Buyouts of the
remaining non-wholly owned Verio ISPs during 1998. See "-- ISP Ownership
Structure." The Company's decentralized regional management structure and equity
incentive programs that are tied to regional performance foster continued
entrepreneurial culture, local responsiveness and internal growth.
    
 
   
     Integrate Operations and Capture Economies of Scale. The Company integrates
and optimizes the operations of the ISPs it acquires by consolidating their
operations into regional operating units with centralized regional management,
connecting their local networks to Verio's high-speed, highly reliable national
backbone, and providing them with Verio's integrated national support services.
These services include national network transit, 7-day X 24-hour network
monitoring and management, customer technical support, a sophisticated billing
and collections system, financial information management through a central,
standardized accounting system, and national marketing and product development
programs. Through this integration of its national infrastructure with its local
ISP operations, the Company believes that it has achieved a significant degree
of operational control and efficiency and has improved the quality, consistency,
and scalability of its services. The Company also has leveraged its national
scale to establish peering relationships, to obtain favorable national
purchasing contracts and to establish strategic relationships with key hardware
and software providers. These providers view Verio's ISPs as a powerful
distribution channel. For example, Verio has entered into an agreement with
Microsoft whereby Verio is offered as an "in the box" Web hosting program for
Microsoft's FrontPage product and for Microsoft's Small Business Server Referral
program, which facilitates small businesses' entry to the Internet using Verio's
network. In addition, Verio has negotiated advantageous volume purchase
agreements with key vendors such as Cisco and Raptor. In addition, Verio has
obtained public and private peering arrangements with every major ISP other than
UUNet, including MCI, Sprint and GTE Internetworking (formerly BBN), as well as
with over 90 smaller domestic and international networks. Furthermore, the
Company's scale also allows it to support a high quality national network and
invest in leading edge systems for network management, billing, customer
service, and financial information.
    
 
     Develop and Offer Enhanced Products and Services to Increase
Revenues. Small and medium sized businesses are purchasing an increasing number
of enhanced products and services as these businesses deploy mission critical
applications on the Internet. As a result, the Company believes that it will be
able to derive incremental revenue from these customers by selling an expanding
array of enhanced services and additional bandwidth to support these services.
The Company accelerated its ability to provide sophisticated Web hosting
                                       43
<PAGE>   51
 
on a national scale through its acquisition of Internet Servers, Inc.
("iServer"). While Internet connectivity and Web hosting constitute the
predominant services offered by Verio today, a number of additional high-margin
enhanced services are being offered by the Company. These additional services
include VPN, security services, electronic commerce, intranet services and other
advanced Internet applications. Verio encourages continued innovation within its
regional operations, and supports the identification and transfer of products,
services and "best practices" among its regional operations. In addition, the
Company's product development groups are focused on additional services to be
developed both internally, through acquisition, and in conjunction with
strategic partners. Verio has entered into, and expects to continue to enter
into, relationships with selected Internet hardware, software, service and
distribution companies to enhance the Company's ability to deliver
cost-effective solutions to its customers, to gain early access to new
technology, to cooperatively market and sell these new products, and to gain
access to their distribution channels for the purpose of lead generation and
customer acquisition.
 
     Build Customer Loyalty and Brand Name Recognition. The Company's goal is to
achieve national recognition as the leading provider of Internet services to
small and medium sized businesses by rebranding its ISPs under the Verio name.
The Company intends to leverage its local presence by continuing to expand and
enhance local technical, distribution and customer support capabilities. By
combining the quality of local service offered through the Company's regional
operations with the Company's national backbone and support services, the
Company expects to generate increased customer loyalty and expanding market
share at the local level while enhancing its national brand. In conjunction with
the consolidation of its ISPs into integrated regional operating units, the
Company has branded these regional operations under the Verio name, with a
regional or local geographical identifier to emphasize its local presence. As
the Company continues to expand, its acquisition strategy will be to continue to
identify and select ISPs that have developed a strong local presence through
quality service, hands-on customer support, local market knowledge and an
entrepreneurial culture.
 
THE VERIO ORGANIZATION
 
   
     To date, the Company has pursued a regional acquisition strategy, acquiring
independent, locally based ISPs in selected geographic regions. In each region,
the Company typically sought a larger regional ISP to serve as the focal point
for the region and as the vehicle for integrating and optimizing the networks
and operations in that region. The Company also has invested in smaller ISPs to
increase its local presence and market share. Having established a presence in
each of its initially targeted regions, the Company has expanded its target
markets to encompass all of the top 50 MSAs and is continuing to add
incrementally to its presence within its existing regions. It is also in the
process of consolidating most of the Verio ISP operations within each region
into single, integrated operating units.
    
 
   
     The Company conducts its operations with both a national and regional
approach. As of April 10, 1998, the Company had acquired the stock or assets of,
or invested in, ISPs in eight regions of the country, and now has substantial
operations in: the Pacific Northwest, serving the primary MSAs in Washington,
Oregon and Idaho; Northern California, serving the greater Bay Area, Stockton
and Sacramento; Southern California, serving the Los Angeles area, Orange County
and San Diego; Texas and Louisiana, serving all of the major cities in Texas as
well as New Orleans; the Northeast, serving the major MSAs from New Jersey to
Boston and Upstate New York; the Mid-Atlantic, serving the Washington DC,
Baltimore, Richmond and the I-95 corridor; and the Midwest, serving Chicago,
Detroit, Ann Arbor, Kansas City, St. Louis, Omaha, Tulsa and Des Moines. In
addition, the Company has funded a start-up operation in the Rocky Mountain
region, which is in the early stages of establishing a presence in the Denver
area and along the Front Range. Verio also has substantially increased its
national Web hosting presence with its acquisition of iServer, based on which
Verio has established a national operating division through which it can offer
Web hosting services to ISP customers throughout its regions. The Company is now
focusing its efforts on seeking greater coverage in the Midwest and establishing
a presence in the Southeast. As of April 10, 1998, the Company had executed
definitive agreements to acquire four additional ISPs. Two of these ISPs will
expand the Company's Midwest presence, one will join the Northeast operations,
and one is located in Florida and is the Company's first acquisition in the
Southeast region. With these four additional ISPs, the Company will serve 36 of
the top 50 MSAs. The revenue attributable to these four proposed ISPs is
estimated to be approximately $2.3 million for the three
    
 
                                       44

months ended December 31, 1997, which would bring the Company's total revenue
for that three month period to $25.5 million. The Company believes that
consummation of each of these acquisitions is probable. Accordingly, financial
information for these acquisitions is reflected in the pro forma financial
statements contained herein. Nonetheless, there can be no assurance that all of
the closing conditions will be satisfied or that the Company will consummate any
or all of these acquisitions. In addition, the Company has executed a
non-binding letter of intent to acquire an additional ISP located in Michigan
which, if consummated, would further enhance the Company's market presence in
the Midwest region.
    
 
   
     The following chart identifies, by operating region, the 33 ISPs acquired
or invested in by Verio, or from which Verio has acquired significant assets, as
of April 10, 1998. It also includes the four ISPs subject to definitive
acquisition agreements as of April 10, 1998, the consummation of which the
Company believes to be probable. The chart provides certain summary information
concerning Verio's revenues for the three months ended December 31, 1997 as if
all such ISPs had been owned by the Company at such date.

PRODUCTS AND SERVICES
    
 
     The Company currently offers, through its regional ISP operations, a
comprehensive range of Internet connectivity and enhanced products and services.
The specific products offered in each market are determined by the needs of the
market and local telco tariffs. The Company intends to continue to develop a
broad range of enhanced products and services independently, through
acquisition, and through strategic relationships with key vendors.
 
     Connectivity Services. Verio offers a variety of connectivity solutions,
which include Internet access and third-party software and hardware
implementations and configuration services, which are offered in bundled and
unbundled packages. Internet access currently includes ISDN, frame relay, leased
line access and dial-up connectivity. The Company is participating in trials for
the deployment of new access technologies, such as xDSL and wireless access. The
Company also offers a full range of customer premise equipment ("CPE") hardware
required to connect to the Internet, including routers, CSU/DSUs, servers and
other products as needed. Verio's regional operating units are able to take
advantage of the Company's national purchasing and leasing relationships with a
variety of partners in order to realize improved hardware pricing, lower cost
leasing arrangements and bundled service offerings. Verio also offers a
selection of software products including browsers, electronic mail, news and
other solutions that permit customers to navigate and utilize the Internet.
Additionally, Verio provides turnkey configuration solutions encompassing such
services as domain name server ("DNS") support, telco line provisioning, IP
address space assignment, router set-up, e-mail configuration, router security
configuration and other set-up services.
 
   
     Enhanced Services. The Company believes that its small and medium sized
business customers will continue to increase their use of the Internet as a
business tool and, as a result, will require an expanding range of enhanced
services. The Company currently offers a variety of enhanced services. In
addition, the Company's national marketing group is focused on developing new
enhanced services through both internal development, acquisition and strategic
relationships with software, hardware and content providers. The Company's
current and planned enhanced services offerings include the following:
    
 
     - Web Hosting and Co-location. Web hosting offers business customers a
       presence on the Internet, enabling them to take advantage of the
       marketing, customer service, internal company information ("intranets")
       and other benefits offered by such presence. Verio offers its customers
       Web hosting services on a national basis as well as through local data
       centers. The services include the full range of Web hosting, Web design,
       Web site maintenance and ongoing consulting services through a
       combination of internal efforts and the use of independent partners. The
       Company also offers Web site co-location, where a customer-owned Web
       server is located at a Verio ISP POP for higher reliability. This
       solution allows the customer to own its own Web server without having to
       maintain and manage the data center environment. The Company's
       acquisition of Utah-based iServer gives the Company access to proprietary
       Web server technology, an extensive network of Web hosting resellers and
       over 25,000 hosted Web sites. The Company believes it will be able to
       leverage iServer's proprietary "virtual server" technology across its
       regional operations to accelerate the growth and increase the
       profitability of its Web hosting product line. In addition to offering
       Web hosting services, the Company has established national Web hosting
       and co-location services by operating high-end, highly reliable data
       centers positioned close to major network access points. The Company is
       consolidating the majority of its Web hosting capability into its
       regional data centers across the country, strategically located near the
       Company's public and private peering points. The Company also intends to
       implement emerging content distribution technologies such as content
       replication ("mirroring") and caching for enhanced end user performance.
       Currently, the Company supports over 35,000 domains and provides hosting
       services to over 1,600 resellers.
 
     - Security. Security solutions are a vital component for most businesses
       connected to the Internet. These solutions, which include firewalls,
       packet filter and proxy servers, give the customer (i) an ability to
       prevent intruders from accessing its corporate network, (ii)
       authentication of users attempting to gain access, and (iii) encryption
       services, providing secured transmission of company data through the
       Internet. The Company currently offers a comprehensive set of firewall
       products from Raptor,
 
                                       47
<PAGE>   55
 
       including the sophisticated Eagle Firewall(TM) and the more simplified
       products known as The Wall(TM). The Company also offers proxy server
       solutions such as the Microsoft Proxy Server. Additionally, the Company
       offers a "managed" security solution that provides ongoing detection and
       prevention of intrusions. The Company plans to expand its security
       product line with new solutions that simplify, reduce cost, or offer
       greater functionality as they become commercially available.
 
     - Virtual Private Network ("VPN"). Many companies today have private data
       communication networks, which are often referred to as wide area networks
       ("WANs") and built on expensive leased lines, to transfer proprietary
       data between office locations. The Internet offers companies a cost-
       effective replacement alternative to WANs through VPNs, which are meant
       to provide secure transmission of private Internet Protocol ("IP")
       traffic through the Internet. Additionally, many companies require that
       their employees have remote access to these private networks from home or
       while traveling. VPN products are available in hardware, software,
       firewall and service provider formats. VPN products are also the basis
       for offering intranet and extranet services. Intranets are
       corporate/organizational networks that rely on Internet-based
       technologies to provide secure links between corporate offices. Extranets
       expand the network to selected business partners through secured links on
       the Internet. Increasingly, companies are finding that intranets and
       extranets can enhance corporate productivity more easily and less
       expensively than proprietary systems. The Company currently offers its
       customers a number of VPN solutions, including Raptor's VPN products and
       is in the process of evaluating additional products to meet the needs of
       customers.
 
     - National Roaming. Employees of small and medium businesses are
       increasingly dependent on accessing their e-mail while on the road.
       Currently, many users either cannot do so because of the limitations of
       their local ISP, or they are required to pay expensive long distance
       access charges. The Company is in the process of implementing a national
       dial-up access roaming product to enable dial-up business customers to
       access the Internet locally as they travel throughout the country and
       abroad.
 
     - Electronic Commerce Solutions. Electronic commerce provides users the
       ability to sell products and services on the Internet. The Company
       currently provides e-commerce capability to over 500 customers by
       providing the three principle functions of electronic commerce: secure
       socket layer, shopping cart support, and transaction processing
       capability. Secure socket layer ("SSL") is provided through its Premier
       Business Partner relationship with Verisign for digital certificates. The
       Company supports a large variety of shopping carts, including Shop Site
       by Icentral, and provides support for third party transaction processing
       through Cybercash and AuthorizeNet. The e-commerce solutions are packaged
       according to the complexity of the individual customer's needs. The
       Company also intends to provide enhanced e-commerce hosting environments,
       as well as to make use of third party software development partners to
       provide certain turnkey e-commerce applications, such as an on-line
       catalogs.
 
     - Professional Services. The Company's target customers typically do not
       have the internal resources or personnel to design and maintain Internet
       services. As more businesses utilize the Internet for mission critical
       applications, the Company expects its customers to rely on their ISP for
       support of many of their information technology applications. As a
       result, the Company believes it will be increasingly important for ISPs
       to offer onsite, technical consulting to customers. The Company currently
       offers a full complement of professional services to its customers,
       including network and system design, Web content creation, security
       system needs analysis and implementation, virtual private network design
       and implementation, and other Internet-related consulting projects. The
       Company intends to invest in additional professional services
       capabilities as they are required to provide customers with turnkey
       Internet solutions.
 
     - Enhanced Products and Services. Customers are increasingly seeking to
       tailor the use of the Internet to their business. Verio intends to serve
       these needs through the packaging and configuration of third party
       applications, such as data storage and retrieval, IP telephony (which
       permits users to make voice calls on the Internet), Internet faxing,
       Internet audio and video conferencing solutions, and other applications
       that may be developed. As businesses commit to using the Internet, the
       Company believes that the advanced applications product category will
       continue to expand, offering additional revenue
 
                                       48
<PAGE>   56
 
       opportunities. For example, the Company currently provides mail list
       services to customers that have a need to send out hundreds of thousands
       of e-mail messages to their customers, suppliers and prospects.
 
   
     Verio has and intends to continue to enter into agreements with Internet
companies to leverage their products, brand names, distribution channels and
other assets. Verio believes that its existing Internet product and service
partners have been attracted to the Company because of its broad geographic
coverage, ability to influence purchase decisions of its business customers, and
the ability of the Verio sales forces to sell complex Internet solutions. The
Company has established strategic relationships with software providers such as
Microsoft, Oracle and Raptor, and equipment providers such as Cisco and
Farallon, and intends to expand its strategic relationships with additional
providers of key products and services. These relationships provide the Company
with benefits including preferred pricing, access to the latest products,
co-marketing with the vendors, tailored product training and access to the
vendor's distribution channels to generate leads for new customers.
    
 
SALES AND MARKETING
 
     Verio offers its products and services through a consultative sales
approach which makes use of local technical talent to understand customer
applications and provide bundled Internet applications solutions consisting of
hardware, software, access and value-added services. Verio believes that this
localized approach will allow it to provide end-to-end customer solutions and
ongoing support. Verio and its ISPs have significant distribution capabilities
both through a direct sales force and indirect channels. The direct sales forces
offer a core base of technically competent, locally based and experienced
Internet sales representatives. Verio is focusing efforts on expanding the
direct sales force, further developing indirect channels and optimizing lead
generation techniques to reduce the cost of new customer acquisitions.
 
   
     The Company currently provides Internet services to over 80,000 customer
accounts. Over 5,000 of these customer accounts receive dedicated connectivity
services from Verio, and over 12,000 represent Web hosting or Web site server
co-location services provided by Verio. Through the Company's Web services, over
35,000 domains (i.e. Verio.net) are hosted. The over 60,000 remaining accounts
are provided dial-up connectivity services, the majority of which are used for
business purposes.
    
 
     Direct Sales. Verio's ISPs have a direct sales force of more than 100
individuals. These local sales representatives have a strong Internet technical
background and understand the local telecommunications tariffs as well as the
needs of their local business community. Additionally, these representatives are
familiar with local companies to assist in implementing customized solutions
such as Web page content development. The Company has developed programs at the
national level to attract and train high quality, motivated sales
representatives that have the necessary technical skills, consultative sales
experience and knowledge of their local markets. These programs include
technical sales training, consultative selling techniques, sales compensation
plan development, and sales representative recruiting profile identification.
Through the effective use of these initiatives, Verio plans to continue to
expand its direct sales force. At the local level, direct marketing techniques
are being employed to target customer segments that would achieve substantial
benefit from the business applications afforded by the Internet. Some direct
marketing tactics include direct mail, telemarketing, seminars and trade show
participation. The Company is working with key vendors to assist in these direct
marketing efforts. Verio co-markets with these vendors through direct mail
programs, joint seminar development and joint trade show involvement.
 
     Resellers and Indirect Sales. The Company has an authorized reseller and
referral program that permits the regional operating units to adapt a formal
indirect distribution program to their markets. The Company believes indirect
channels are a significant contributor to its growth. The Company already has
over 1,600 formal and informal reseller arrangements established. The authorized
reseller program offers reseller partners the ability to share in the on-going
revenue stream of customers they bring to Verio. Reseller partners include
system integrators, value-added resellers and other companies that have an
established relationship with the prospective customer base, and have a sales
force capable of selling Internet services as a part of the reseller's suite of
services. Referral partners, including organizations such as Web designers,
advertising agencies or property managers, are another source of customer leads.
The referral program targets organizations that are
                                       49
<PAGE>   57
 
less capable of selling Internet services or where Internet services fall
outside their core business interests. The benefits of these programs to Verio
include greater market reach without fixed overhead costs and the ability to use
the partners to assist in the delivery of complete solutions to meet customer
needs. In addition to local resellers, Verio is working with several national
companies to expand its indirect sales capability.
 
     Branding. The Company's branding approach is intended to transfer Verio's
national strength to its ISPs while transferring each ISP's local presence and
support to the Verio brand. In conjunction with the consolidation of its ISPs
into integrated regional operating units, the Company is branding these regional
operations under the Verio name, with a regional or local geographical
identifier to emphasize its local presence. Additionally, the Company's national
public relations efforts serve to raise the awareness of Verio, which the
Company expects will continue to generate leads.
 
VERIO NATIONAL NETWORK
 
   
     Overview. Verio owns and operates a national network, providing a high
bandwidth, highly reliable data transmission path connecting Verio's customers
to the Internet, which the Company believes is adequate for the provision of
current and future planned access and enhanced services needs. The Company's
national network interconnects more than 15 national nodes and over 180 local
POPs across the United States. The Company believes that aggregating the
bandwidth and capacity requirements of its regional operations onto one national
network provides operational control and efficiency, reduces costs, provides
redundancy, and results in a higher quality service, thereby addressing some of
the most significant challenges that an ISP faces in supporting its customers.
Verio's national infrastructure also incorporates several other elements
critical to maintaining the highest quality Internet service, including a high
capacity and reliable national network, peering relationships with other
national ISPs, sophisticated network management tools and engineering support
services. The reliability of the national network is the result of many factors,
including but not limited to redundant routers and other critical hardware,
carrier class facilities at POP locations (such as back up power, fire
suppression and climate control), and redundant telecommunications lines.
    
 
   
     Network Infrastructure. As of April 1998, the national network carried
traffic for 25 of the Verio ISPs and the remaining ISPs' traffic will be added
as growth drives the need for additional capacity, as private and public peering
is implemented and as their current transit contracts expire. It is currently
anticipated that by the end of the second quarter of 1998, five additional Verio
ISPs will deliver traffic to the Verio network.

     Currently, the national network architecture includes a presence at
selected national exchange points and redundant network nodes to link the
Company's regional networks to the national network. As of February 1998,
Verio's network included connectivity at MAE West, MAE East and the NY NAP, each
of which is a major national exchange point for ISPs. The Company also has a
presence at the Palo Alto Internet Exchange (PAIX), NASA Ames and a number of
other regional connecting points, including Seattle, Washington; Portland,
Oregon; Sacramento and San Diego, California; Denver, Colorado; Dallas and
Houston, Texas; Chicago, Illinois; Ann Arbor, Michigan; Philadelphia,
Pennsylvania; and Boston, Massachusetts. Each of these Verio locations features
leading router technology. The equipment is located in facilities leased from a
variety of telecommunications providers, including MCI, Sprint, MFS, Brooks and
others. These access points are linked, using a nationwide, high-speed DS-3 (45
Mbps) and OC-3 (155 Mbps) ATM, and DS-3 and OC-3 clear line network
infrastructure, utilizing capacity leased from a variety of national telco
providers, including Sprint, MCI, WorldCom and Qwest. The ATM portion of the
network relies on Sprint's 4-fiber ring SONET network. Sprint's SONET
architecture is designed to survive multiple failures with near instant
restoration to full capacity, thereby providing highly reliable performance.
This combination of clear channel circuits, ATM and router architecture provides
reliability to the network through path diversity and redundancy. Verio's
regional operating units either co-locate at these access nodes or lease
connectivity from a local service provider such as an RBOC or other LEC to
connect to the Verio equipment.
    
 
   
     Work has begun to add national access nodes to serve additional parts of
the Midwest, Southern California, Texas, the Northeast and the Southeast which
the Company currently plans to put on-line during the second and third quarters
of 1998. Multiple national access nodes facilitate connection to Verio's
national network by its regional operations. The Company plans to add additional
private peering points and access nodes as it acquires more ISPs and expands
operations, and to further increase network capacity as the need for additional
bandwidth arises.
    
 
   
     The national network is planned to allow for rapid expansion of bandwidth
through scaleable design supported by multiple local access and interexchange
carriers to provide the required bandwidth. The Company has begun the migration
of selected links from ATM to clear line. It is anticipated that the Company
will require nationwide OC-3 capacity in late 1998 to handle its projected
traffic requirements. The Company anticipates the potential need to exceed OC-3
speeds in 1999.
    
 
   
     On March 31, 1998, the Company entered into a 15-year Capacity and Services
Agreement (the "Capacity Agreement") with Qwest, under which the Company will
have access to long haul capacity and ancillary services on Qwest's planned
16,285 mile MacroCapacity(SM) Fiber Network. Over the first seven years of the
term of the Capacity Agreement (the "Commitment Term"), the Company must
purchase, and Qwest must provide, not less than $100.0 million, in the
aggregate, of such capacity and services (the "Commitment"), at agreed upon
prices. The amount of capacity represented by the minimum Commitment would
satisfy less than 50% of the Company's projected long haul capacity requirements
over the Commitment Term. However, the Company has the right to order capacity
and services in excess of the Commitment level, and after the expiration of the
Commitment Term, at the same agreed upon prices. The Company also currently is
party to a number of other long haul capacity agreements with additional
telecommunication providers. These agreements are for various terms (of up to 5
years), and have varied pricing. Verio anticipates that it will satisfy a
substantial portion of its capacity and ancillary services needs under the
Capacity Agreement, because it believes that the agreed upon pricing levels will
significantly reduce the per unit costs that it otherwise would pay under its
other existing long haul capacity agreements.
    
 
   
     The Company believes that the currently installed Cisco routers will be
sufficient to support its traffic routing needs up to and including OC-3 speeds.
To handle the routing at speeds higher than OC-3, new technology will be
required. The Company is investigating various options to support these higher
speeds and bandwidth requirements. Verio's options include switching, higher
capacity and faster routers, or hybrid routing and switching solutions.
    
 
   
     Peering Relationships. By implementing its own national network and
establishing peering relationships with other national ISPs, the Company
believes it can lower the cost of its Internet transit and increase the
performance and reliability of its network operations. Peering is the Internet
practice under which ISPs
    
 
                                       51
<PAGE>   59
 
exchange each other's traffic without the payment of settlement charges. The
basis on which the large national ISPs make peering available or impose
settlement charges is evolving as the provision of Internet access and related
services has expanded and the dominance of a small group of national ISPs has
driven industry peering policy. Recently, companies that have previously offered
peering have cut back or eliminated peering relationships and are establishing
new, more restrictive criteria for peering. The Company believes that
substantial traffic volume and national scale will continue to be the focal
criteria necessary to establish and maintain peering relationships. As a result,
it has become increasingly important for companies seeking to take advantage of
peering to have significant traffic, a national network and monitoring
capability.
 
   
     The Company has established peering relationships with nearly all of the
major national ISPs, as well as with over 90 smaller domestic and international
networks, and is evaluating further private peering relationships with other
national ISPs. Some large network providers now prefer to peer at private
exchange points rather than at national exchange points. This preference
represents the desire to accomplish the exchange of high bandwidth traffic in a
more efficient manner rather than to risk congestion and equipment failure at
public exchange points. The Company has moved its GTE Internetworking and DIGEX
public peering points to private peering locations and is in the process of
moving its MCI public peering points to private peering locations. Verio also is
evaluating additional private peering proposals from other national ISPs. The
Company currently anticipates that, as Verio's traffic grows, more peering
relationships can be obtained. However, no assurance can be given that peering
relationships will continue to be made available to the Company. Even if these
relationships are not maintained or established, Verio believes that it will be
more economical for Verio to maintain an exchange point transit agreement than
to pay other national ISPs for transit. See "Risk Factors -- Dependence upon
Implementation of Network Infrastructure; Establishment and Maintenance of
Peering Relationships."
    
 
   
     National Network Management. The Company considers world-class network
management an essential capability for network monitoring and expansion,
maintaining high customer satisfaction and improving network quality. The
Company has established a 7-day X 24-hour NOC to allow continuous monitoring of
the network and to provide a single point of contact for real-time network
status information and customer technical problem resolution. The NOC is
designed to provide real-time alarming, event correlation, traffic management
and forecasting, and distributed notification of the network events and network
status. The Company utilizes many leading edge systems to provide the NOC
capabilities. The Company currently monitors the national network and the local
networks of approximately 17 of the ISPs it has acquired. The Company plans to
provide network and customer monitoring throughout its regional operations by
the end of 1998.
    
 
     Engineering Support Services. The Company has negotiated national level
telecommunications contracts with LECs, such as MFS/WorldCom, providing
favorable terms for local transport. The Company plans to expand national
purchasing and leasing benefits as well as technical planning and support to
improve the performance, reliability and economics of its regional networks.
National level purchasing benefits include both cost and vendor performance
issues as well as the provisioning of spare equipment and additional technical
support from the suppliers. National level distribution agreements have been
negotiated with a number of additional national-scope suppliers. The Company's
relationships with Sprint and MCI provide discounted services including leased
line, local access and long distance. Co-location agreements have also been
established with companies such as Sprint, MCI, Brooks, MFS/WorldCom and Digital
Equipment Corporation. The Company is pursuing additional vendor and
telecommunication relationships in an effort to reduce the cost of equipment and
improve network quality.
 
     Technical Planning and Support. The national engineering team provides
engineering support for routing configurations, telecommunications management
and pricing, development of local networks and purchasing and contract
negotiation. The national engineering team also works with the regional
engineering teams to nationalize certain network elements, improve performance
and reduce network costs. Support includes Internet protocol addressing support,
training and technology. This effort of sharing ideas and best practices among
the national team and the regions is intended to enhance the engineering talent
available locally and to share best practices nationally.

NATIONAL SUPPORT SERVICES
 
     In addition to its national network and network monitoring capability,
Verio has developed and implemented three critical national support services
designed to increase operational efficiencies and enhance the quality,
consistency and scalability of the Company's services. These support services
include 7-day X 24-hour customer technical support and service, financial
information management through a central, standardized accounting system, and a
sophisticated billing and collections system. The strategy of creating a
partnership between local support teams and Verio's established national support
services enables the Company to capture economies of scale, improve quality and
responsiveness, and increase productivity, while allowing local personnel to
focus on relationships with customers.
 
   
     Customer Technical Support. Verio's customer care combines the
responsiveness and on-site capabilities of local ISP presence with the scale
economies of a national customer support center in order to deliver customer
care to businesses. While local, independent ISPs bring the benefits of
understanding customer needs and providing hands-on support demanded by their
customers, they lack the ability to cost-effectively scale internal resources to
independently support their growing customer base. The Company's national
customer support center (located in Dallas, Texas) enables Verio to provide
7-day X 24-hour responsiveness while maintaining the ability to provide on-site
installation assistance, hands-on troubleshooting and access to local experts
who understand the customer's business. The Company is currently providing
customer care services to 21 of the ISPs it has acquired and will offer services
to all of the Verio regional operations as the national customer support center
continues to expand throughout 1998. The support center team is utilizing a
leading customer support trouble ticketing and workflow management system
offered by the Vantive Corporation. The system offers the Company the ability to
track, route, and report on customer issues and provides significant benefit in
ensuring quality and timely care to customers. The Company believes that the
market for ISP services, as a whole, is evolving towards the provision of
credits to customers for service outages as a result of ISP network failures.
While the Company has not provided general service warranties or instituted a
uniform policy to date relating to the extent or the provision of service
credits, certain of the Verio ISPs have done so and continue to do so in certain
circumstances.
    
 
   
     Financial Information Management. The Company is in the process of
converting all of its ISPs to the PeopleSoft(TM) financial reporting system and
the ADP payroll/human resources system, in order to provide a central,
standardized accounting system. Currently, 20 of the Verio ISPs are utilizing
the financial reporting system and eight are utilizing the payroll human
resources system. These systems enable Verio to cost effectively increase the
productivity and quality of administrative support by standardizing operational
systems such as payroll, payables, purchasing and financial reporting. These
enhancements are part of the Company's initiative to implement continuous
improvement methodology and to create a learning organization.
    
 
   
     Billing and Collections. The Company has implemented the Kenan Systems' EC
Arbor billing solution which offers high quality, flexibility,
cost-effectiveness and scalability. Kenan is a leading billing solutions
provider to the telecommunications industry, providing accurate, timely, and
easy-to-understand invoicing. This system currently serves 16 of the Verio ISPs.
The Company is aggressively rolling out this billing platform to all of its
regional operations and will continue on the path toward centralized management
of billing operations.
    
 
NTT STRATEGIC RELATIONSHIP
 
   
     On April 7, 1998, the Company entered into agreements establishing a
strategic relationship with NTT. These agreements provide for an investment by
NTT or one of its affiliates in the Company, concurrent with and conditioned
upon the consummation of the proposed IPO, for up to 12.5% of Company's fully
diluted Common Stock (after giving effect to the proposed IPO and the NTT
Investment) up to a maximum investment of $100.0 million, at a 3.25% discount to
the price to public in the proposed IPO. In connection with the NTT Investment,
NTT is entitled to designate one member to serve on the Company's Board of
Directors. See "Principal Stockholders -- NTT Investment."
    
 
   
     In addition, the Company and NTT America entered into a three year Outside
Service Provider Agreement (the "OSP Agreement"), which will take effect upon
the closing of the NTT Investment.
    
                                       53
<PAGE>   61
 
   
Pursuant to the OSP Agreement, the Company will be designated as the preferred
provider of Internet access and related services to customers of NTT America on
a reseller basis. Verio and NTT will connect their backbones and establish a
peering and transit relationship. During the term of the OSP Agreement, NTT
America will pay the Company for the services provided by the Company at
predetermined rates reflective of the strategic relationship between the
parties. Within 30 days after the IPO Closing (as defined), NTT America and the
Company have agreed to establish certain working groups to develop the details
for implementation of the specific technical and administrative aspects arising
under the OSP Agreement.
    
 
ISP OWNERSHIP STRUCTURE
 
   
     While the Company now typically seeks to acquire 100% of new ISPs, the
Company's early acquisition strategy was to rapidly build mass and scale by
acquiring less than 100% of its ISPs. In each case where the Company acquired
less than 100% of an ISP initially, it obtained the right to acquire the
remaining equity in the future at a price based on either agreed upon revenue
multiples or the fair market value of the ISP. As part of its integration
strategy, the Company is in the process of effecting the Buyouts of most of its
remaining non-wholly owned ISPs through the use of cash on hand and the issuance
of equity. As of April 10, 1998, Verio had consummated the Buyout of 12 ISPs.
Verio currently expects to effect the Buyouts of the remaining four ISPs that it
did not initially acquire 100% during the remainder of 1998. However, there can
be no assurance that the Company will be able to complete these additional
Buyouts at the times, or on the terms and conditions, that it currently
contemplates.
    
 
     As the Company completes the Buyouts, in general, the ISPs in each region
are consolidated into a single, integrated regional operating subsidiary which
is wholly owned by the Company. In certain instances, some of the ISPs may
continue to exist as separate, indirect, wholly owned subsidiaries of Verio, but
operated as part of the particular integrated operating region.
 
   
     Verio also currently holds a 20% interest in V-I-A Internet, Inc., a
start-up company which was formed to pursue a consolidation strategy similar to
that of the Company in international markets. Other investors in that entity
include certain of Verio's current stockholders. Justin L. Jaschke, Chief
Executive Officer of the Company, currently serves as the Chairman of the Board
of V-I-A Internet, and Steven C. Halstedt, Chairman of the Board of the Company,
currently serves as the acting President of V-I-A Internet. See "Management."
    
 
COMPETITION
 
   
     The market for Internet connectivity and related services is extremely
competitive. The Company anticipates that competition will continue to intensify
as the use of the Internet grows. The tremendous growth and potential market
size of the Internet access market has attracted many new start-ups as well as
existing businesses from different industries. Current and prospective
competitors include, in addition to other national, regional and local ISPs,
long distance and local exchange telecommunications companies, cable television
companies, direct broadcast satellite and wireless communications providers, and
on-line service providers. The Company believes that a reliable national
network, knowledgeable salespeople and the quality of technical support
currently are the primary competitive factors in the Company's target market,
and that price is usually secondary to these factors.
    
 
   
     ISPs. According to Boardwatch magazine's directory of Internet Service
Providers, there are currently over 4,000 ISPs in the United States, consisting
of national, regional and local providers. The Company's current primary
competitors include other ISPs with a significant national presence which focus
on business customers, such as UUNet, GTE Internetworking (formerly BBN),
PSINet, Concentric Network and DIGEX. While the Company believes that its level
of local service and support and target market focus distinguish it from these
competitors, some of these competitors have significantly greater market
presence, brand recognition, and financial, technical and personnel resources
than the Company, and have extensive coast-to-coast Internet backbones. The
Company also competes with unaffiliated regional and local ISPs in its targeted
geographic regions.
    
 
                                       54
<PAGE>   62
 
     Telecommunications Carriers. All of the major long distance companies (also
known as interexchange carriers or IXCs), including AT&T, MCI, and Sprint, offer
Internet access services and compete with the Company. The recent sweeping
reforms in the federal regulation of the telecommunications industry have
created greater opportunities for LECs, including the RBOCs, to enter the
Internet connectivity market. In order to address the Internet connectivity
requirements of the current business customers of long distance and local
carriers, the Company believes that there is a move toward horizontal
integration through acquisitions of, joint ventures with, and the wholesale
purchase of connectivity from, ISPs. The WorldCom/MFS/UUNet consolidation, the
NETCOM/ICG merger, the Intermedia/DIGEX merger and GTE's acquisition of BBN are
indicative of this trend. Accordingly, Verio expects that it will experience
increased competition from the traditional telecommunications carriers. Many of
these telecommunications carriers, in addition to their substantially greater
network coverage, market presence, and financial, technical and personnel
resources, also have large existing commercial customer bases. Furthermore,
telecommunications providers may have the ability to bundle Internet access with
basic local and long distance telecommunications services. Such bundling of
services may have an adverse effect on the Company's ability to compete
effectively with the telecommunications providers and may result in pricing
pressure on the Company that would have an adverse effect on the Company's
business, financial condition and results of operations. The Company believes
that its local presence and its strong technical and data-oriented sales force
is an important feature distinguishing it from the centralized voice-oriented
sales approach typified by the current Internet connectivity services offered by
the IXCs and LECs.
 
     Cable Companies, Direct Broadcast Satellite and Wireless Communications
Companies. Many of the major cable companies have announced that they are
exploring the possibility of offering Internet connectivity, relying on the
viability of cable modems and economical upgrades to their networks. MediaOne
Group and TCI have recently announced trials to provide Internet cable service
to their residential customers in select areas. However, the cable companies are
faced with large-scale upgrades of their existing plant equipment and
infrastructure in order to support connections to the Internet backbone via
high-speed cable access devices. Additionally, their current subscriber base and
market focus is residential which requires that they partner with
business-focused providers or undergo massive sales and marketing and network
development efforts in order to target the business sector. Several
announcements also have recently been made by other alternative service
companies approaching the Internet connectivity market with various wireless
terrestrial and satellite-based service technologies. These include Hughes
Network System's DirecPC product that provides high-speed data through direct
broadcast satellite technology; CAI Wireless System's announcement of an MMDS
wireless cable operator launching data services via 2.5 to 2.7 GHz and
high-speed wireless modem technology; Cellularvision's announcement that it is
offering Internet access via high-speed wireless LMDS technology; and Winstar,
which currently offers high-speed internet access to business customers over the
38 GHz spectrum.
 
     On-line Service Providers. The predominant on-line service providers,
including America Online, CompuServe, Microsoft Network, and Prodigy, have all
entered the Internet access business by engineering their current proprietary
networks to include Internet access capabilities. The Company competes to a
lesser extent with these on-line service providers.
 
     Recently, there have been several announcements regarding the planned
deployment of broadband services for high speed Internet access by cable and
telephone companies through new technologies such as cable modems and xDSL.
While these providers have initially targeted the residential consumer, it is
likely that their target markets will expand to encompass the Company's targeted
markets, which may significantly affect the pricing of the Company's service
offerings.
 
PROPERTIES
 
     The Company's corporate headquarters is located in Englewood, Colorado
where the Company leases approximately 39,200 square feet of office space. The
Company's lease agreement, which commenced February 1, 1998, is for a term of
five years. The Company also has executed a lease covering 12,600 square feet of
space in the InfoMart in Dallas, Texas, where the Company maintains its network
operations center and customer support center. That lease expires on June 30,
2002. The Company also leases space, typically
                                       55
<PAGE>   63
 
less than 200 square feet, in various geographic locations to house network
infrastructure and telecommunications equipment. Operational functions are
principally located in the offices of its regional operations. The Verio ISPs
typically are party to lease agreements for administrative office space
sufficient for their respective personnel, as well as smaller site leases to
house their network equipment.
 
EMPLOYEES
 
   
     As of March 31, 1998, the Company employed approximately 901 people,
including full-time and part-time employees at its corporate headquarters in
Colorado, its network operations and customer support center in Texas and at its
controlled ISPs. The Company considers its employee relations to be good. None
of the employees of the Company is covered by a collective bargaining agreement.
    
 
TRADEMARKS AND TRADE NAMES
 
     The Company filed for federal trademark protection of "Verio" on November
29, 1996. This application is pending and the Company has no assurance that it
will be granted. Trademark protections for the Verio mark also have been applied
for in the European Economic Community, as well as in Japan. Additionally,
corporate name reservations for the name "Verio Inc." have been filed in all
fifty states. In conjunction with the consolidation of its ISPs into regional
operating entities, the ISPs have migrated to the Verio brand name, with a
regional or local geographical identifier appended.
 
LEGAL PROCEEDINGS
 
     The Company is not currently party to any material legal proceedings.

(1) All options were granted at an exercise price per share equal to at least
    the fair market value of the Common Stock on the date of grant, as
    determined by the Board of Directors.
 
(2) The potential realizable value is calculated based on the fair market value
    on the date of grant, which is equal to the exercise price of the options,
    assuming that the stock appreciates in value from the date of grant
    compounded annually until the end of the option term at the rate specified
    (5% or 10%) and that the option is exercised and sold on the last day of the
    option term for the appreciated stock price. Potential realizable value is
    net of the option exercise price. The assumed rates of appreciation are
    specified in the rules and regulations of the Commission and do not
    represent the Company's estimate or projection of future stock price. Actual
    gains, if any, resulting from stock option exercises and Common Stock
    holdings are dependent on the future performance of the Common Stock and
    overall stock market conditions. There can be no assurance that the amounts

EMPLOYMENT AGREEMENTS
 
     As a general matter, the Company does not enter into employment agreements,
and has not entered into employment agreements with any of its executive
officers. Rather, the employment relationships with each executive officer are
"at will." However, in connection with the initial employment of each executive
officer, the Company and the executive executed an offer letter, in which the
general compensation and benefits
 
                                       63
<PAGE>   71
 
   
provided to the executive are outlined, including base salary, targeted annual
bonus, option grants and employee benefits. The base salary and targeted bonus
levels for each of the executive officers remains the same in 1998 as in 1997.
However, upon consummation of the proposed IPO, the base salary for Mr. Jaschke
will be increased to $260,000, which will result in an increase in his annual
targeted bonus level of 30% to 40% of his base salary.
    
 
   
COMPENSATION PROTECTION AGREEMENTS
    
 
   
     The Company has entered into compensation protection agreements (the
"Compensation Protection Agreements") with all of the Named Executive Officers
and certain additional officers (collectively, the "Protected Officers") of the
Company. Each of the Compensation Protection Agreements contain substantially
similar terms. The form of Compensation Protection Agreement has been filed as
an exhibit to the Company's Registration Statement of which this Prospectus is a
part. The Compensation Protection Agreements will be for a term of three years
from April 1, 1998 (the "Effective Date"), subject to automatic yearly
extensions. In no event will the Compensation Protection Agreements terminate
within 12 months of a Change in Control of the Company. "Change in Control"
includes the following:
    
 
   
          (a) An acquisition (other than directly from the Company) of any
     voting securities of the Company (the "Voting Securities") by any Person
     (as defined in the Exchange Act) immediately after which such Person has
     Beneficial Ownership (as defined in the Exchange Act) of 40% or more of the
     combined voting power of the Company's then outstanding Voting Securities.
     In determining whether a Change in Control has occurred, Voting Securities
     which are acquired in a "Non-Control Acquisition," as defined in the
     Compensation Protection Agreements, do not constitute an acquisition which
     would cause a Change in Control;
    
 
   
          (b) The individuals who, as of date the Compensation Protection
     Agreements were approved by the Board, are members of the Board (the
     "Incumbent Board"), cease for any reason to constitute at least a majority
     of the Board (subject to certain provisos);
    
 
   
          (c) Approval by stockholders of the Company of: (1) a merger,
     consolidation or reorganization involving the Company, unless such merger,
     consolidation or reorganization ("event") satisfies certain specified
     conditions;
    
 
   
          (d) Any other event that at least two-thirds of the Incumbent Board
     determines constitutes a Change in Control; and
    
 
   
          (e) If a Protected Officer's employment is terminated prior to a
     Change in Control and the Board determines that such termination was at the
     request of a third party who has indicated an intention or taken steps to
     effect a Change in Control and who subsequently effectuates a Change in
     Control, or occurred in connection with, or in anticipation of, a Change in
     Control which actually occurs, then a Change in Control is considered to
     have occurred with respect to that Protected Officer.
    
 
   
     Upon termination within 12 months of a Change in Control, each Protected
Officer will receive the following severance benefits:
    
 
   
          (i) If a Protected Officer's employment is terminated within 12 months
     of a Change in Control for Cause (as defined in the Compensation Protection
     Agreements) or by reason of the Protected Officer's Disability (as defined
     in the Compensation Protection Agreements), death, retirement, or by the
     Protected Officer other than for Good Reason (as defined in the
     Compensation Protection Agreements), then the Company must pay to the
     Protected Officer the Accrued Compensation (as defined below) due through
     the date of termination (the "Termination Date"). Accrued Compensation
     includes base salary, reimbursement for reasonable and necessary expenses
     incurred by the Protected Officer on behalf of the Company during the
     period ending on the Termination Date, and vacation pay.
    
 
                                       64
<PAGE>   72
 
   
          (ii) If a Protected Officer's employment is terminated within 12
     months of a Change of Control for any other reason than specified above,
     the Protected Officer will receive:
    
 
   
             (A) his or her Accrued Compensation;
    
 
   
             (B) an amount equal to the product of a fraction, the numerator of
        which is the number of days in the Company's fiscal year through the
        Termination Date and the denominator of which is 365, and the bonus
        amount, which will be the greater of 100% of the last annual incentive
        payment paid or payable to the Protected Officer prior to the
        Termination Date, and the Protected Officer's incentive target for the
        fiscal year in which the Change in Control occurs (the "Bonus Amount");
    
 
   
             (C) an amount equal to two (2) times the sum of the Protected
        Officer's annual base salary in effect immediately prior to the Change
        in Control, plus the Bonus Amount. However, the amount paid to Mr.
        Jaschke will be three (3) times that sum;
    
 
   
             (D) until the third anniversary of the Termination Date, the same
        rights with respect to benefits provided by the Company, as were
        provided to the Protected Officer as of the Effective Date, or, if
        greater, at any time within 90 days preceding the date of the Change in
        Control; and
    
 
   
             (E) the immediate vesting and removal of all restrictions on any
        outstanding incentive awards granted to the Protected Officer under the
        Company's stock option and other stock incentive plans or arrangement.
    
 
   
     The Compensation Protection Agreements will further provide that the
Protected Officers will not be required to mitigate the amount of any payment by
seeking employment or otherwise. Protected Officers may be entitled to
additional compensation or benefits in accordance with the Company's employee
benefit plans and other applicable programs, policies and practices then in
effect. The Compensation Protection Agreements will contain a "gross-up"
provision pursuant to which any Severance Payment, which would be subject to
certain excise taxes occurring as a result of Change of Control, would include
an additional gross-up payment resulting in the Protected Officer retaining an
additional amount equal to excise tax.
    
 
STOCK OPTION AND INCENTIVE PLANS
 
  1996 Stock Option Plan
 
   
     The 1996 Stock Option Plan was adopted and approved by the Board of
Directors in May 1996 and by the stockholders of the Company in June 1996. In
February 1998, the 1996 Stock Option Plan was amended, with the approval of the
Board, to reserve a total of 2,205,300 shares of Common Stock for issuance under
this plan. As of April 10, 1998, options to purchase 115,933 shares of Common
Stock granted under the 1996 Stock Option Plan had been exercised, options to
purchase 2,043,967 shares of Common Stock were outstanding and options to
purchase 45,400 additional shares of Common Stock remained available for grant.
The outstanding options were exercisable at a weighted average exercise price of
$6.59 per share. Outstanding options to purchase an aggregate of 1,480,667
shares were held by employees who are not officers or directors of the Company.
Of the 115,933 shares issued upon exercise of options, a total of 47,500 were
issued upon exercise prior to their respective exercise vesting dates, as
permitted by the terms of the 1996 Stock Option Plan. As a result, these shares
are subject to repurchase by the Company at their respective exercise prices,
until the date on which they would have become exercisable. The 1996 Stock
Option Plan will terminate in 2006, unless sooner terminated by the Board of
Directors.
    
 
     The Board of Directors has delegated administration of the 1996 Stock
Option Plan to its Compensation Committee (the "Committee"). The Committee is
constituted to comply with the rules under Rule 16b-3 of the Securities Exchange
Act of 1934 (the "Exchange Act"). Awards under the 1996 Stock Option Plan may
consist of (i) options to purchase Common Stock that are designed to qualify,
under Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"),
as "incentive stock options" ("Incentive Stock Options") or (ii) options to
purchase Common Stock that are not described in Sections 422 or 423 of the Code
("Non-Qualified Stock Options" and, collectively with Incentive Stock Options,
"Options").
 
                                       65
<PAGE>   73
 
   
     The Committee has discretion to grant Incentive Stock Options to employees
and officers (including directors who are employees) of the Company or any
Affiliate (as defined in the Plan) of the Company and Non-Qualified Stock
Options to employees, officers, directors or consultants of the Company and its
Affiliates. The Committee may set the terms of such grants, subject to
applicable restrictions in the 1996 Stock Option Plan. Incentive Stock Option
grants are subject to the following limitations: (i) the term of any Incentive
Stock Option may not be longer than ten years, provided that the term of any
Incentive Stock Option granted to an individual possessing more than 10% of the
combined voting power of the Company or an Affiliate (a "10% Holder") may not be
longer than five years; (ii) the aggregate fair market value of all shares
underlying Incentive Stock Options granted to an individual that first become
exercisable in any calendar year may not exceed $100,000; and (iii) the exercise
price of Incentive Stock Options may not be less than the fair market value of
the underlying shares on the grant date, provided that the exercise price of any
Incentive Stock Option granted to a 10% Holder may not be less than 110% of the
fair market value of the underlying shares on the grant date. With respect to
Non-Qualified Stock Options, the exercise price may not be less than 85% of the
fair market value of the underlying shares on the grant date. As of February 27,
1998, no such below-market grant has been made.
    
 
     During an optionee's lifetime, an Incentive Stock Option is exercisable
only by the optionee and no Incentive Stock Option may be transferred by the
optionee other than by will or the laws of descent and distribution. During an
optionee's lifetime (or a transferee pursuant to a qualified domestic relation
order), a Non-Qualified Stock Option is exercisable only by the optionee and no
Non-Qualified Stock Option may be transferred by the optionee other than by will
or the laws of descent and distribution or pursuant to a qualified domestic
relation order satisfying the requirements of the prior version of Rule 16b-3
under the Exchange Act. An optionee whose continuous status as an employee,
director or consultant of the Company terminates for any reason (other than
termination because of death or disability) may exercise, in the three-month
period following such cessation (unless such Options terminate or expire sooner
by their terms), or such longer or shorter period as specified in the Option,
that portion of the optionee's Options that is exercisable at the time of such
cessation. In the event the optionee becomes disabled, the Options vested as of
the date of disability may be exercised prior to the earlier of such Option's
specified expiration date or 12 months from the date of the optionee's
disability, or such longer or shorter period as specified in the Option. In the
event the optionee dies, the Options vested as of the date of disability may be
exercised prior to the earlier of such Option's specified expiration date or 18
months from the date of the optionee's disability, or such longer or shorter
period as specified in the Option.
 
     In the event of (i) a dissolution or liquidation of the Company, (ii) a
merger or consolidation in which the Company is not the surviving corporation,
(iii) a reverse merger in which the Company is the surviving corporation but the
shares of the Company's outstanding common stock immediately prior to such
merger are converted into other property, whether in the form of securities,
cash or otherwise, or (iv) any other capital reorganization in which the
Company's shareholders receive less than 50% of the outstanding voting shares of
the surviving corporation: (a) any surviving corporation shall assume any
Options outstanding under the 1996 Stock Option Plan, (b) such Options shall
continue in full force and effect, or (c) the Options shall terminate if not
exercised prior to such event.
 
  1997 California Stock Option Plan
 
   
     The Company's 1997 California Stock Option Plan (the "1997 California
Plan") was adopted by the Board of Directors in February 1997, and approved by
the Company's stockholders in April 1997. In February 1998, the 1997 California
Plan was amended, with the approval of the Board, to reserve a total of 795,400
shares of Common Stock for issuance under this plan. This amendment has been
approved by the Company's stockholders. As of April 10, 1998, no options to
purchase shares of Common Stock had been exercised under the 1997 California
Plan, options to purchase 447,850 shares of Common Stock were outstanding and
options to purchase an additional 347,550 shares of Common Stock remained
available for grant. The outstanding options were exercisable at a weighted
average exercise price of $9.16 per share. Outstanding options to purchase an
aggregate of 341,140 shares were held by employees who are not officers or
directors of the Company.
    
 
                                       66
<PAGE>   74
 
   
     The 1997 California Plan may be administered by the Board of Directors or
the Committee (either, the "Plan Administrator"). The 1997 California Plan
provides for the granting to employees of the Company and of its subsidiaries or
parent corporations of Incentive Stock Options, and for the granting to
employees and independent contractors of Non-Qualified Stock Options. The Plan
Administrator has the power to determine the terms of the Options granted,
including the exercise price, number of shares subject to the Option and the
exercisability thereof, and the form of consideration payable upon exercise.
Options granted under the 1997 California Plan are not transferable by the
optionee other than by will or by the laws of descent or distribution, and each
Option is exercisable during the lifetime of the optionee only by such optionee.
The exercise price of all Incentive Stock Options granted under the 1997
California Plan must be at least equal to the fair market value, as determined
by the Board of Directors, of the Common Stock on the grant date. The exercise
price of all Non-Qualified Stock Options granted under the 1997 California Plan
must be at least 85% of the fair market value, as determined by the Plan
Administrator, of the Common Stock on the grant date. With respect to any
participant who owns stock possessing more than 10% of the voting power or value
of all classes of the Company's outstanding capital stock, the exercise price of
any Incentive Stock Option or Non-Qualified Stock Option granted must equal at
least 110% of the fair market value of the Common Stock on the grant date and
the term of the Option must not exceed five years. The term of all other Options
granted under the 1997 California Plan may not exceed ten years. The
consideration for exercising any Option may consist of cash, check, shares of
Common Stock, a promissory note, the assignment of part of the proceeds from the
sale of shares acquired upon exercise of the Options or any combination thereof
as specified in the agreement evidencing the Option.
    
 
     The 1997 California Plan provides that in the event of a merger of the
Company with or into another corporation or a consolidation, sale of
substantially all of the Company's assets or like transaction involving the
Company in which the Company's stockholders before the transaction do not retain
a majority interest in the Company, each Option may be assumed or an equivalent
Option may be substituted by a successor corporation. If the successor
corporation chooses not to assume the Options under the 1997 California Plan,
the Options not otherwise exercisable will terminate immediately prior to the
consummation of the transaction.
 
     Unless terminated sooner, the 1997 California Plan will terminate
automatically in 2007. The Board has the authority to amend, suspend or
terminate the 1997 California Plan, subject to stockholder approval of certain
amendments and provided no such action may affect any share of Common Stock
previously issued and sold or any Option previously granted under the 1997
California Plan without the optionees consent.
 
  1998 Stock Incentive Plan
 
   
     The Company's 1998 Stock Incentive Plan (the "1998 Stock Incentive Plan"),
which was adopted by the Board of Directors in February 1998, was amended and
restated as of March 19, 1998 and has been approved by the Company's
stockholders. From and after the proposed IPO, all further option grants will be
made solely under the 1998 Stock Incentive Plan. As of April 10, 1998, no
options to purchase shares of Common Stock had been exercised under the 1998
Stock Incentive Plan, options to purchase 1,138,123 shares of Common Stock were
outstanding and options to purchase an additional 611,189 shares of Common Stock
remained available for grant. The outstanding options were exercisable at a
weighted average exercise price of $12.02 per share. The purpose of the 1998
Stock Incentive Plan is to attract and retain the best available personnel, to
provide additional incentive to employees, directors and consultants of the
Company and its related entities and to promote the success of the Company's
business. The 1998 Stock Incentive Plan provides for the granting to employees
of Incentive Stock Options and the granting of nonstatutory stock options, stock
appreciation rights, dividend equivalent rights, restricted stock, performance
units, performance shares, and other equity-based rights ("Awards") to
employees, directors and consultants of the Company and its related entities.
Initially, 165,000 shares of Series D-1 Preferred Stock and 1,749,300 shares of
Common Stock, together with any shares of Common Stock represented by Awards
under the 1996 Stock Option Plan which are forfeited, expire or are cancelled
following the adoption of the 1998 Stock Incentive Plan, will be reserved for
issuance under the 1998 Stock Incentive Plan. Upon and after the proposed IPO,
6,199,300 shares of Common Stock will be reserved for issuance under the 1998
Stock Incentive Plan, together with (a) any
    
 
                                       67
<PAGE>   75
 
   
shares of Common Stock available for future awards under the 1997 California
Plan as of the proposed IPO and (b) any shares of Common Stock represented by
Awards under the 1996 Stock Option Plan and the 1997 California Plan (the "Prior
Plans"), that are forfeited, expire or are cancelled following the proposed IPO.
In connection with the adoption of the 1998 Stock Incentive Plan, the Board
determined that the Company will limit the issuance of Awards under the 1998
Stock Incentive Plan such that the aggregate number of shares subject to Awards
granted under the 1998 Stock Incentive Plan and the Prior Plans will not at any
time exceed 15% of the Company's outstanding fully-diluted equity.
    
 
     With respect to Awards granted to directors or officers, the 1998 Stock
Incentive Plan is administered by the Board of Directors or a committee
designated by the Board of Directors constituted to permit such Awards to be
exempt from Section 16(b) of the Exchange Act in accordance with Rule 16b-3
thereunder. With respect to Awards granted to other participants, the 1998 Stock
Incentive Plan is administered by the Board of Directors or a committee
designated by the Board of Directors. In each case, the Plan Administrator shall
determine the provisions, terms and conditions of each Award, including, but not
limited to, the Award vesting schedule, repurchase provisions, rights of first
refusal, forfeiture provisions, form of payment (cash, shares of Common Stock,
or other consideration) upon settlement of the Award, payment contingencies and
satisfaction of any performance criteria.
 
     Incentive Stock Options are not transferable by the optionee other than by
will or the laws of descent or distribution, and each Incentive Stock Option is
exercisable during the lifetime of the optionee only by such optionee. Other
Awards shall be transferable to the extent provided in the agreement evidencing
the Award.
 
     The exercise price of Incentive Stock Options must be at least equal to the
fair market value of the Common Stock on the date of grant, and the term of the
option must not exceed ten years. The term of other Awards will be determined by
the Plan Administrator. With respect to an employee who owns stock possessing
more than 10% of the voting power of all classes of the Company's outstanding
capital stock, the exercise price of any Incentive Stock Option must equal at
least 110% of the fair market value of the Common Stock on the grant date and
the term of the option must not exceed five years. The exercise price or
purchase price, if any, of other Awards will be such price as determined by the
Plan Administrator, but not less than 85% of the fair market value of the stock.
The consideration to be paid for the shares of Common Stock upon exercise or
purchase of an Award will be determined by the Plan Administrator and may
include cash, check, shares of Common Stock, or the assignment of part of the
proceeds from the sale of shares acquired upon exercise or purchase of the
Award.
 
     Where the Award agreement permits the exercise or purchase of the Award for
a certain period of time following the recipient's termination of service with
the Company, disability, or death, the Award will terminate to the extent not
exercised or purchased on the last day of the specified period or the last day
of the original term of the Award, whichever occurs first.
 
     Unless terminated sooner, the 1998 Stock Incentive Plan will terminate
automatically in 2008. The Board has the authority to amend, suspend or
terminate the 1998 Stock Incentive Plan subject to stockholder approval of
certain amendments and provided no such action may affect Awards previously
granted under the 1998 Stock Incentive Plan.
 
   
  1998 Employee Stock Purchase Plan
    
 
   
     The Company's 1998 Employee Stock Purchase Plan (the "Stock Purchase Plan")
was approved by the Board of Directors in February 1998 and has been approved by
the Company's stockholders. The Stock Purchase Plan is intended to qualify as an
"employee stock purchase plan" under Section 423 of the Code in order to provide
employees of the Company with an opportunity to purchase Common Stock through
payroll deductions. An aggregate of 3,000,000 shares of the Company's Common
Stock has been reserved for issuance under the Stock Purchase Plan and available
for purchase thereunder, subject to adjustment in the event of a stock split,
stock dividend or other similar change in the Common Stock or the capital
structure of the Company. All employees of the Company (and employees of
"subsidiary corporations" and "parent corporations" of the Company (as defined
by the Code) designated by the administrator of the Stock Purchase Plan) whose
customary employment is for more than five months in any calendar year and more
    
                                       68
<PAGE>   76
 
   
than 20 hours per week are eligible to participate in the Stock Purchase Plan.
Employees hired after the consummation of the proposed IPO are eligible to
participate in the Stock Purchase Plan, subject to a six-month waiting period
after hiring. Non-employee directors, consultants, and employees subject to the
rules or laws of a foreign jurisdiction that prohibit or make impractical the
participation of such employees in the Stock Purchase Plan are not eligible to
participate in the Stock Purchase Plan.
    
 
     The Stock Purchase Plan designates Purchase Periods, Accrual Periods and
Exercise Dates. Purchase Periods are generally overlapping periods of 12 months.
The initial Purchase Period will begin on the effective date of the Stock
Purchase Plan, which is the effective date of the Company's Registration
Statement relating to the Company's initial public offering of its Common Stock,
and end on May 14, 1999. Additional Purchase Periods will commence each May 15
and November 15. Accrual Periods are generally six month periods, with the
initial Accrual Period commencing on the effective date of the Stock Purchase
Plan and ending on November 14, 1998. Thereafter, Accrual Periods will commence
each May 15 and November 15. Exercise Dates are the last day of each Accrual
Period. In the event of a merger of the Company with or into another
corporation, the sale of all or substantially all of the assets of the Company,
or certain other transactions in which the stockholders of the Company before
the transaction own less than 50% of the total combined voting power of the
Company's outstanding securities following the transaction, the administrator of
the Stock Purchase Plan may elect to shorten the Purchase Period then in
progress.
 
     On the first day of each Purchase Period, a participating employee is
granted a purchase right which is a form of option to be automatically exercised
on the forthcoming Exercise Dates within the Purchase Period during which
deductions are to be made from the pay of participants (in accordance with their
authorizations) and credited to their accounts under the Stock Purchase Plan.
When the purchase right is exercised, the participant's withheld salary is used
to purchase shares of Common Stock of the Company. The price per share at which
shares of Common Stock are to be purchased under the Stock Purchase Plan during
any Accrual Period is the lesser of (a) 85% of the fair market value of the
Common Stock on the date of the grant of the option (the commencement of the
Purchase Period) or (b) 85% of the fair market value of the Common Stock on the
Exercise Date (the last day of an Accrual Period). The participant's purchase
right is exercised in this manner on both Exercise Dates arising in the Purchase
Period unless, on the first day of any Accrual Period, the fair market value of
the Common Stock is lower than the fair market value of the Common Stock on the
first day of the Purchase Period. If so, the participant's participation in the
original Purchase Period is terminated, and the participant is automatically
enrolled in the new Purchase Period effective the same date.
 
     Payroll deductions may range from 1% to 10% (in whole percentage
increments) of a participant's regular base pay and bonuses, exclusive of
overtime, shift-premiums or commissions. Participants may not make direct cash
payments to their accounts. The maximum number of shares of Common Stock which
any employee may purchase under the Stock Purchase Plan during an Accrual Period
is 1,250 shares. Certain additional limitations on the amount of Common Stock
which may be purchased during any calendar year are imposed by the Code.
 
     The Stock Purchase Plan will be administered by the Board of Directors or a
committee designated by the Board, which will have the authority to terminate or
amend the Stock Purchase Plan (subject to specified restrictions) and otherwise
to administer the Stock Purchase Plan and to resolve all questions relating to
the administration of the Stock Purchase Plan.
 
401(k) PLAN
 
     In January 1997, the Company implemented an employee savings and retirement
plan (the "401(k) Plan") covering certain of the Company's employees who have at
least one month of service with the Company and have attained the age of 21.
Pursuant to the 401(k) Plan, eligible employees may elect to reduce their
current compensation by up to the lesser of 20% of such compensation or the
statutorily prescribed annual limit ($10,000 in 1998) and have the amount of
such reduction contributed to the 401(k) Plan. The Company may make
contributions to the 401(k) Plan on behalf of eligible employees. Employees
become 20% vested in these Company contributions after one year of service, and
increase their vested
 
                                       69
<PAGE>   77
 
percentages by an additional 20% for each year of service thereafter. The 401(k)
Plan is intended to qualify under Section 401 of the Internal Revenue Code of
1986, as amended, so that contributions by employees or by the Company to the
401(k) Plan, and income earned on the 401(k) Plan contributions, are not taxable
to employees until withdrawn from the 401(k) Plan, and so that contributions by
the Company, if any, will be deductible by the Company when made. The trustee
under the 401(k) Plan, at the direction of each participant, invests the 401(k)
Plan employee salary deferrals in selected investment options. The Company made
no contributions to the 401(k) Plan in 1996 or in 1997. The Company does not
presently expect to make any contributions to the 401(k) Plan during the fiscal
1998.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     The Chairman of the Compensation Committee is Mr. Schovee. No member of the
Compensation Committee was at any time during the fiscal year ended December 31,
1997, or at any other time, an officer or employee of the Company. No member of
the Compensation Committee of the Company serves as a member of the board of
directors or compensation committee of any entity that has one or more executive
officers serving as a member of the Company's Board of Directors or Compensation
Committee. See "Certain Transactions" for a description of transactions between
the Company and entities affiliated with members of the Compensation Committee.
 
LIMITATION ON LIABILITY AND INDEMNIFICATION MATTERS
 
     The Company's Restated Certificate of Incorporation and bylaws provide that
the Company shall indemnify to the fullest extent permitted by Section 145 of
the DGCL, as it now exists or as amended, all directors and officers pursuant
thereto. The Company's Restated Certificate of Incorporation and bylaws also
authorize the Company to indemnify its employees and other agents, at its
option, to the fullest extent permitted by Section 145, as it now exists or as
amended. The Company intends to enter into agreements to indemnify its directors
and officers, in addition to indemnification provided for in the Company's
charter documents. These agreements, among other things, provide for the
indemnification of the Company's directors and officers for certain expenses
(including attorneys' fees), judgments, fines and settlement amounts incurred by
any such person in any action or proceeding, including any action by or in the
right of the Company, arising out of such person's services as a director or
officer of the Company, any subsidiary of the Company or any other company or
enterprise to which such person provides services at the request of the Company
to the fullest extent permitted by applicable law. The Company believes that
these provisions and agreements will assist the Company in attracting and
retaining qualified persons to serve as directors and officers.
 
     Section 102(b)(7) of the DGCL permits a corporation to provide in its
certificate of incorporation that a director of the corporation shall not be
personally liable to the corporation or its stockholders for monetary damages
for breach of fiduciary duty as a director, except for liability (i) for any
breach of the director's duty of loyalty to the corporation or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL,
or (iv) for any transaction from which the director derived an improper personal
benefit. The Company's Restated Certificate of Incorporation will provide for
the elimination of personal liability of a director for breach of fiduciary
duty, as permitted by Section 102(b)(7) of the DGCL.
 
   
     The underwriting agreement to be executed by the Company and the
Underwriters in connection with the proposed IPO (the "Underwriting Agreement")
provides for indemnification by the Underwriters under certain circumstances of
directors, officers and controlling persons of the Company against certain
liabilities, including liabilities under the Securities Act.
    
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the provisions contained in the Certificate of Incorporation and
Bylaws of the Company, the DGCL, the Underwriting Agreement, or otherwise, the
Company has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the Company
of expenses incurred or paid by a director, officer or controlling person of the
Company in the successful defense of any action, suit, or proceeding) is
asserted by such director, officer or controlling person in connection with the
                                       70
<PAGE>   78
 
Common Stock being registered hereunder, the Company will, unless in the opinion
of its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
it is against public policy as expressed in the Securities Act and will be
governed by the final adjudication of such issue.
 
     The Company intends to purchase and maintain insurance on behalf of the
officers and directors insuring them against liabilities that they may incur in
such capacities or arising out of such status.

Agreement, the Company, the Series A Purchasers, the Series B Purchasers, the

Stockholders Agreement (the "Stockholders Agreement"), which replaced the Series
B Stockholders Agreement. See "-- Stockholders Agreement."

     Pursuant to the terms of the Stockholders Agreement, the holders of the
Series A Preferred Stock, the Series B Preferred Stock and the Series C

with respect to the Company. At any time after the effective date of the first
registration statement filed by the Company under the Securities Act of 1933, as
amended (the "Securities Act"), holders
 
                                       73
<PAGE>   81
 
   
of 25% or more of the Registrable Securities (as defined in the Stockholders
Agreement) may require the Company to effect registration under the Securities
Act of their Registrable Securities, subject to the Board of Directors' right to
defer such registration for a period of up to 180 days. In addition, if the
Company proposes to register securities under the Securities Act (other than a
registration relating either to the sale of securities to employees pursuant to
a stock option, stock purchase or similar plan or a transaction under Rule 145
of the Securities Act), then any of the Investors has a right (subject to
quantity limitations determined by underwriters if the offering involves an
underwriting) to request that the Company register such holder's Registrable
Securities. All registration expenses incurred in connection with up to two
long-form and all short-form and piggyback registrations will be borne by the
Company. Each Investor will pay for selling expenses pro rata on the basis of
the number of shares sold by such Investor. The Company has agreed to indemnify
the Investors (including the officers, directors, partners, agents, employees
and representatives, and each person controlling such Investor within the
meaning of Section 15 of the Securities Act) against all expenses, claims,
losses, damages and liabilities (or actions, proceedings or settlements in
respect thereof) arising out of or based on any untrue or alleged untrue
statement of a material fact contained in any prospectus, offering circular or
other document (including any related registration statement, notification or
the like) incident to any such registration, qualification or compliance, or
based on any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, or any violation by the Company of the Securities Act or any rule or
regulation thereunder applicable to the Company and relating to action or
inaction required of the Company in connection with any such registration,
qualification or compliance, and will reimburse each such Investor for any legal
and any other expenses reasonably incurred in connection with investigating and
defending or settling any such claim, loss, damage, liability or action;
provided, however, that the Company will not be liable in any such case to the
extent that such claim, loss, damage, liability or expense arises out of or is
based on any untrue statement or omission based upon written information
furnished to the Company by such Investor and stated to be specifically for use
therein. This indemnification does not apply to amounts paid in settlement of
any such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Company.
    
 
   
     Subject to certain exceptions, the Company has a right of first refusal to
purchase shares of Common Stock held by Management Holders (as defined in the
Stockholders Agreement) which, to the extent not purchased by the Company, are
subject to an additional right of first refusal by the Investors according to
their respective pro rata shares. In addition, transfers of Common Stock held by
Investors are subject to a right of first refusal by other Investors who are
also holders of Common Stock. Subject to certain exceptions, upon the issuance
by the Company of any Common Stock or any other equity securities, each of the
Specified Investors (as defined in the Stockholders Agreement) has the
preemptive right to purchase its pro rata share of up to 80% of the securities
so offered according to their respective pro rata interests. If any Specified
Investor declines to exercise such right in full, the remaining electing
specified Investors are entitled to purchase such Specified Investor's
unpurchased portion of the offered securities on a pro rata basis. All
preemptive rights and rights of first refusal contained in the Stockholders
Agreement terminate upon consummation of the proposed IPO.

     B, and C Preferred Stock outstanding at April 10, 1998; and (iii) 2,237,554
     shares of Common Stock issuable upon conversion of the Series D-1 Preferred
     Stock issued and expected to be issued in connection with the acquisitions
     and Buyouts completed or probable as of April 10, 1998, totalling
     22,093,487 shares of capital stock of the Company. Percentage of beneficial
     ownership after the proposed IPO is based on 31,732,214 total shares of
     capital stock outstanding, which includes the shares of capital stock
     outstanding prior to the proposed IPO identified above plus (i) 4,638,727
     shares of Common Stock to be sold by the Company to NTT for approximately
     $78.5 million (based upon an assumed initial public offering of 5,000,000
     shares of Common Stock at an assumed price to public of $17.50 per share in
     the proposed IPO) concurrently with the proposed IPO and (ii) 5,000,000
     shares of Common Stock to be sold pursuant to the proposed IPO. In
     computing the number of shares beneficially owned by a person and the
     percentage ownership of that person, shares of Common Stock subject to
     options or warrants that are currently exercisable or exercisable within 60
     days of April 10, 1998 are deemed outstanding; provided, however that such
     shares are not deemed outstanding for the purpose of computing the
     percentage of ownership of any other person. Except as indicated in the
     footnotes to this table and pursuant to applicable community property laws,
     each of the persons named in this table has sole voting and investment
     power with respect to the shares set forth opposite such stockholder's
     name.
    
 
   
 (2) Includes warrants for 400,000 shares of Common Stock exercisable within 60
     days. As a result of the acquisition of Brooks by WorldCom, which resulted
     in Brooks becoming a wholly owned subsidiary of WorldCom, WorldCom may be
     deemed to indirectly beneficially own the shares owned by Brooks.
    
 
   
 (3) Does not include 71,205 shares of the Company's capital stock held by
     Centennial Entrepreneurs Fund V, L.P. ("Entrepreneurs Fund"). Holdings V is
     the sole general partner of Entrepreneurs Fund and may be deemed to

     decisions regarding the voting and disposition of shares beneficially owned
     by Entrepreneurs Fund. Centennial V disclaims beneficial ownership of the
     shares held by Entrepreneurs Fund and Entrepreneurs Fund disclaims
     beneficial ownership of the shares held by Centennial V. In addition,

     Centennial IV, and Centennial IV disclaims beneficial ownership of the
     shares held by Centennial V.
    
 
   
 (4) The sole General Partner of Centennial IV is Holdings IV and the sole
     General Partner of Centennial V is Holdings. Holdings IV and Holdings V may
     be deemed to indirectly beneficially own the shares owned by Centennial IV
     and Centennial V, respectively. Mr. Halstedt is a general partner of
     Holdings IV and Holdings V and may be deemed to be the indirect beneficial
     owner of the shares owned by Centennial IV and Centennial V. Mr. Halstedt
     disclaims beneficial ownership of shares held by Centennial IV and
     Centennial V. In addition, this amount does not include 141,265 shares of
     the Company's capital stock held by Holdings LLC, of which Mr. Halstedt is
     a unit holder. Centennial Holdings, Inc. ("Holdings Inc."), of which Mr.
     Halstedt is an officer and director, is the sole Managing Member of
     Holdings LLC and may be deemed to beneficially own shares directly
     beneficially owned by Holdings LLC. However, Mr. Halstedt, acting alone,
     does not have voting or investment power with respect to any of the shares
     directly held by either Holdings Inc. or Holdings LLC, and as a result, Mr.
     Halstedt disclaims beneficial ownership of the shares held by Holdings LLC.

NTT INVESTMENT
    
 
   
     NTT Stock Purchase Agreement and NTT Investment Agreement. Pursuant to a
Stock Purchase and Master Strategic Relationship Agreement, dated as of April 7,
1998, between the Company and NTT (the "NTT Stock Purchase Agreement"), NTT
agreed to purchase, concurrent with and conditioned upon the consummation of the
proposed IPO (the "IPO Closing"), a number of shares of the Company's Common
Stock equal to the lesser of (i) 12.5% of the total number of shares of Common
Stock, on a fully diluted and fully converted basis (calculated as of the IPO
Closing after giving effect to the proposed IPO and the sale to NTT), or (ii)
the quotient of $100.0 million divided by the "Per Share Price" payable by NTT.
The "Per Share Price" to be paid by NTT will be equal to the Price to Public in
the proposed IPO multiplied by 96.75% (subject to certain adjustments in the
event that shares of Common Stock are issued at less than the Per Share Price
prior to the IPO Closing). In the event that the applicable waiting period under
the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), with respect to the purchase of the Common Stock by NTT shall not have
expired or been terminated prior to the IPO Closing, then, in lieu of shares of
Common Stock, NTT will purchase from the Company shares of the Company's Series
X Junior Convertible Preferred Stock (the "Convertible Preferred Shares"). The
Convertible Preferred Shares, which are not entitled to any voting rights except
as required by applicable corporate law, will convert automatically into Common
Stock upon the expiration or termination of the applicable waiting period,
including any extension thereof, under the HSR Act.
    
 
   
     The Company and NTT also entered into an Investment Agreement, dated as of
April 7, 1998 (the "NTT Investment Agreement"), providing for certain
arrangements generally effective from and after the purchase of shares by NTT
under the NTT Stock Purchase Agreement. Pursuant to the NTT Investment
Agreement, the Company agreed to appoint an individual designated by NTT to the
Board of Directors of the Company. The NTT designee will serve for an initial
term ending as of the third annual stockholder meeting following the IPO
Closing. Thereafter, the Company has agreed, subject to certain exceptions, to
nominate as a member of the Board of Directors at each subsequent election of
the applicable class of directors a person designated by NTT who will be subject
to election by the stockholders of the Company. Additionally, NTT will have the
right to designate up to three individuals to be employed by the Company in
corporate development, technical and/or marketing positions to assist in
implementing and carrying out the commercial relationship between Verio and NTT.
    
 
   
     The Investment Agreement imposes certain limitations on NTT's ability to
dispose of the shares of Common Stock that it acquires. In particular, NTT has
granted to the Company certain rights of first offer and rights of first refusal
which apply, under certain circumstances, in the event that NTT proposes to sell
some or all of the shares that it acquires. The specific terms of these rights
vary depending upon the quantity of shares proposed to be sold and other terms
of the proposed sale. In addition, NTT has agreed on behalf of itself and its
affiliates to certain "standstill" restrictions pursuant to which NTT and its
affiliates may make open market or privately negotiated purchases of additional
voting securities (including Common Stock) so long as the total holdings of NTT
and its affiliates do not exceed 17.5% of the Company's fully diluted Common
Stock after taking into account such acquisition. The Company also granted NTT
certain registration rights with respect to the Common Stock it acquires. See
"Certain Transactions -- Description of Capital Stock -- Registration Rights."
    
 
   
     The NTT Stock Purchase Agreement may be terminated prior to the IPO Closing
only in certain limited circumstances, including in the event that the sale of
shares to NTT has not occurred by July 31, 1998. The NTT Investment Agreement
will terminate automatically upon any termination of the NTT Stock Purchase
Agreement.

                         DESCRIPTION OF THE 1997 NOTES
    
 
   
     Set forth below is a summary of certain provisions of the New 1997 Notes.
The New 1997 Notes will be issued under the 1997 Indenture between the Issuer
and the Trustee. A copy of the 1997 Indenture may be obtained upon request from
the Issuer, 8005 South Chester Street, Suite 200, Englewood, Colorado 80112;
attention: General Counsel; telephone: (303) 645-1900.
    
 
   
     Except as otherwise indicated below, the following summary applies to both
the Old 1997 Notes and the New 1997 Notes. As used herein, the term "1997 Notes"
means the Old 1997 Notes and the New 1997 Notes, unless otherwise indicated.
    
 
   
     The form and terms of the New 1997 Notes will be identical in all material
respects to the form and terms of the Old 1997 Notes, except that the New 1997
Notes will be registered under the Securities Act, and therefore such New 1997
Notes will not be subject to certain transfer restrictions and, registration
rights applicable to the Old 1997 Notes. See "The Exchange Offers."
    
 
   
     The 1997 Notes are issued under the 1997 Indenture, a copy of the form of
which is available upon request. The 1997 Indenture is 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 1997 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 1997 Indenture,
including the definitions of certain terms therein and those terms made a part
of the 1997 Indenture by reference to the Trust Indenture Act, as in effect on
the date of the 1997 Indenture. The definitions of certain capitalized terms
used in the following summary are set forth below under "Certain Definitions."
    
 
GENERAL
 
   
     The 1997 Notes are general senior obligations of the Issuer. The 1997 Notes
are collateralized by a first priority security interest in the Escrow Account
described under "-- Disbursement of Funds; Escrow Account." The 1997 Notes have
been 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 1997 Notes are payable, and the 1997 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 1997 Notes, except in certain circumstances for any tax or other
governmental charge that may be imposed in connection therewith.
    
 
MATURITY, INTEREST AND PRINCIPAL
 
   
     The 1997 Notes are limited to $100,000,000 aggregate principal amount after
the Refinancing and will mature on June 15, 2004. Interest on the 1997 Notes
will accrue at a rate of 13 1/2% per annum and be payable in cash semi-annually
in arrears on each June 15 and December 15 (each, an "Interest Payment Date"),
commencing December 15, 1997, to registered holders of 1997 Notes, on the June 1
or December 1, as the case may be, immediately preceding such Interest Payment
Date. Interest on the 1997 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 the Issue Date. Cash 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 and/or premium (whether upon
redemption or otherwise), cash interest will accrue on the amount in default at
the rate of interest borne by the 1997 Notes. Interest on overdue principal and
premium and, to the extent permitted by law, on overdue installments of interest
will accrue at the rate of interest borne by the 1997 Notes.

REDEMPTION
 
   
     Optional Redemption. The 1997 Notes are redeemable, at the option of the
Issuer, in whole or in part, on or after June 15, 2002 upon not less than 30 nor
more than 60 days' written notice at the redemption prices (expressed as
percentages of principal amount) 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 June 15 of each of the years indicated
below:
    
 
<TABLE>
<CAPTION>
                            YEAR                              PERCENTAGE
                            ----                              ----------
<S>                                                           <C>
2002........................................................    106.75%
2003........................................................    100.00%
</TABLE>
 
   
     Notwithstanding the foregoing, in the event that after the Issue Date and
prior to June 15, 1999 the Issuer issues, in one or more transactions, Capital
Stock (other than Disqualified Stock) of the Issuer to Brooks or one or more
Strategic Equity Investors for aggregate gross cash proceeds of $50.0 million or
more (an "Equity Sale"), the Issuer may redeem, at its option, up to a maximum
of 33 1/3% of the initially outstanding aggregate principal amount of 1997 Notes
from the net proceeds thereof at a redemption price equal to 113.5% of the
principal amount of the 1997 Notes, together with accrued and unpaid interest to
the date of redemption; provided that not less than $100.0 million aggregate
principal amount of 1997 Notes is outstanding following such redemption. Any
such redemption may only be effected once and must be effected upon not less
than 30 nor more than 60 days' notice given within 30 days after such Equity
Sale.
    
 
   
     Mandatory Redemption. The Issuer is not required to make any mandatory
sinking fund payments in respect of the 1997 Notes. However, (i) following the
occurrence of a Change of Control, the Issuer is required to make an offer to
purchase all outstanding 1997 Notes at a price of 101% of the principal amount
thereof (determined at the date of purchase), plus accrued interest thereon, if
any, to the date of purchase, and (ii) upon the occurrence of an Asset Sale, the
Issuer may be obligated to make an offer to purchase all or a portion of the
outstanding 1997 Notes at a price of 100% of the principal amount, thereof
(determined at the date of purchase), plus accrued and unpaid interest, if any,
to the date of purchase. See "-- Certain Covenants -- Change of Control" and
"-- Certain Covenants -- Disposition of Proceeds of Asset Sales," respectively.
    
 
   
     Selection; Effect of Redemption Notice. In the case of a partial
redemption, selection of the 1997 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 an
Equity Sale shall be made on a pro rata basis or on as nearly a pro rata basis
as practicable (subject to DTC procedures). No 1997 Notes of a principal amount
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 1997 Notes to be redeemed at its registered
address. If any 1997 Note is to be redeemed in part only, the notice of
redemption that relates to such 1997 Note shall state the portion of the
principal amount thereof to be redeemed. A new 1997 Note in a principal amount
equal to the unredeemed portion thereof will be issued in the name of the holder
thereof upon surrender for cancellation of the original 1997 Note. Upon giving
of a redemption notice, interest on 1997 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 1997 Notes will
cease to be outstanding.
    
 
DISBURSEMENT OF FUNDS; ESCROW ACCOUNT
 
   
     The 1997 Notes are collateralized, pending disbursement pursuant to the
Escrow and Security Agreement dated as of June 24, 1997, among the Issuer, the
Trustee and First Trust National Association, as Escrow Agent (the "Escrow
Agreement"), by a pledge of the Escrow Account (as defined in the Escrow
Agreement). The Issuer deposited approximately $46.6 million of the net proceeds
from the sale of the Old 1997 Notes issued pursuant to the Initial 1997 Notes
Offering (the "Escrow Collateral"), representing funds that, together with the
proceeds from the investment thereof, were sufficient to pay interest on the
1997 Notes
    
 
                                       79
<PAGE>   87
 
   
for five scheduled interest payments through December 15, 1999 (but not any
Additional Interest (as defined) arising under the 1997 Notes Registration
Rights Agreement).
    
 
   
     The Issuer entered into the Escrow Agreement providing for the grant by the
Issuer to the Trustee, for the ratable benefit of the holders of Old 1997 Notes
and New 1997 Notes, as the case may be, of security interests in the Escrow
Collateral. All such security interests will collateralize the payment and
performance when due of all obligations of the Issuer under the 1997 Indenture
and the 1997 Notes, as provided in the Escrow Agreement. The Liens created by
the Escrow Agreement are first priority security interests in the Escrow
Collateral. The ability of holders to realize upon any such funds or securities
may be subject to certain bankruptcy law limitations in the event of the
bankruptcy of the Issuer.
    
 
   
     Pursuant to the Escrow Agreement, funds may be disbursed from the Escrow
Account only to pay interest on the 1997 Notes (or, if a portion of the 1997
Notes has been retired by the Issuer, funds representing the lesser of (i) the
excess of the amount sufficient to pay interest through and including December
15, 1999 on the 1997 Notes not so retired and (ii) the interest payments which
have not previously been made on such retired 1997 Notes for each Interest
Payment Date through and including the Interest Payment Date to occur on
December 15, 1999 shall be paid to the Issuer if no Default then exists under
the 1997 Indenture). As a result of the Refinancing, the Company was refunded
approximately $13.3 million from the escrow account for the 1997 Notes, of which
approximately $1.9 million was used to pay accrued and unpaid interest on the
$50.0 million principal amount of Old 1997 Notes repurchased from Brooks. As of
          , 1998, approximately $     million remained in the Escrow Account.
    
 
   
     Pending such disbursements, all funds contained in the Escrow Account have
been invested in U.S. Government Securities. Interest earned on the U.S.
Government Securities have been and will be, when earned, placed in the Escrow
Account. Upon the acceleration of the maturity of the 1997 Notes, the Escrow
Agreement provides for the foreclosure by the Trustee upon the net proceeds of
the Escrow Account. Under the terms of the 1997 Indenture, the proceeds of the
Escrow Account shall be applied, first, to amounts owing to the Trustee in
respect of fees and expenses of the Trustee and, second, to all obligations
under the 1997 Notes and the 1997 Indenture. Under the Escrow Agreement,
assuming that the Issuer makes the first five scheduled interest payments on the
1997 Notes in a timely manner with funds or U.S. Government Securities held in
the Escrow Account, all of the U.S. Government Securities will be released from
the Escrow Account.
    
 
RANKING
 
   
     The indebtedness of the Issuer evidenced by the 1997 Notes ranks senior in
right of payment to all subordinated indebtedness of the Issuer and pari passu
in right of payment with all other existing and future unsubordinated
indebtedness of the Issuer.
    
 
   
     The Issuer is a holding company with limited assets and no business
operations of its own. The Issuer operates its business through its
subsidiaries. Any right of the Issuer and its creditors, including holders of
the 1997 Notes, to participate in the assets of any of the Issuer's subsidiaries
upon any liquidation or administration of any such subsidiary are subject to the
prior claims of the subsidiary's creditors, including trade creditors. For a
discussion of certain adverse consequences of the Issuer being a holding company
and of the terms of potential future indebtedness of the Issuer and its
subsidiaries, see "Risk Factors -- Holding Company Structure and Need to Access
Subsidiary Cash Flows."
    
 
CERTAIN COVENANTS
 
   
     Set forth below are certain covenants that are contained in the 1997
Indenture.
    
 
   
     Limitation on Additional Indebtedness. The 1997 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
that (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
    
                                       80
<PAGE>   88
 
pro forma effect to such incurrence (including the application of the net
proceeds therefrom), the Consolidated Pro Forma Interest Coverage Ratio would be
greater than or equal to 1.8 to 1.0 if such Indebtedness is incurred prior to
June 30, 1999 or 2.5 to 1.0 if such Indebtedness is incurred on or after June
30, 1999.
 
   
     Limitation on Restricted Payments. The 1997 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 and all Designation Amounts does not exceed an amount equal
     to the sum of, without duplication, (a) 50% of the Consolidated Net Income
     of the Issuer accrued on a cumulative basis during the period beginning on
     July 1, 1997 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), 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 issue and sale (other than to a
     Restricted Subsidiary of the Issuer) of its Capital Stock (other than
     Disqualified Stock) on or after the Issue Date (including upon exercise of
     warrants, options or rights), plus (c) the aggregate net proceeds received
     by the Issuer from the issuance (other than to a Restricted 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, 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 (except for Investments made (1) pursuant
     to clause (vii) of the second following paragraph that are not subject to
     clause (e) or (f) of this paragraph below, and (2) pursuant to clauses
     (viii) or (ix) of the second following paragraph), 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, plus
     (f) an amount equal to the amount of any Investment constituting a
     Restricted Payment made after the Issue Date in an ISP which has been
     included as a Restricted Payment under this clause (iii) pursuant to the
     last paragraph of this covenant to the extent such ISP thereafter (1)
     becomes a Wholly Owned Restricted Subsidiary or is merged with the Issuer
     or (2) is a New ISP that becomes a Restricted Subsidiary or is merged with
     the Issuer, less, in either such case, any amounts credited pursuant to the
     immediately preceding clause (d) in respect of any such Investment, minus
     (g) 50% of the principal amount of any Indebtedness incurred pursuant to
     clause (g) of the definition of "Permitted Indebtedness." For purposes of
     the preceding clauses (b)(y) and (c), as applicable, 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.
 
     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
 
                                       81
<PAGE>   89
 
   
thereof if at such date of declaration such payment would be permitted by the
provisions of the 1997 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 Restricted 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 Restricted
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 1997 Notes; provided that any such
net cash proceeds are excluded from clause (iii)(b) of the second preceding
paragraph; (iv) (a) so long as no Default shall have occurred and be continuing,
Investments constituting Restricted Payments by the Issuer or any Restricted
Subsidiary in a New ISP or a person that becomes a New ISP as a result of such
Investment and (b) so long as no Default shall have occurred and be continuing,
Investments constituting Restricted Payments by the Issuer or any Restricted
Subsidiary in an Existing ISP (x) made out of the net cash proceeds of a
substantially concurrent sale of Capital Stock (other than Disqualified Stock)
of the Issuer (provided that any such proceeds are excluded from clause (iii)(b)
of the second preceding paragraph) or (y) such that the aggregate amount of all
Investments in Existing ISPs that are made after the Issue Date pursuant to this
subclause (b)(y) would not exceed $25.0 million in aggregate; (v) bonds, notes,
debentures or other securities received as a result of Asset Sales pursuant to
and in compliance with the covenant "Disposition of Proceeds of Asset Sales";
(vi) 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 Issuer or one of its Subsidiaries; provided that payments
shall not exceed $2.0 million in any fiscal year in the aggregate or $4.0
million in the aggregate during the term of the 1997 Notes; (vii) 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 a
substantially concurrent (1) capital contribution to the Issuer or (2) issue or
sale of Capital Stock (other than Disqualified Stock) of the Issuer (other than
to a Restricted Subsidiary of the Issuer); provided that any such proceeds are
excluded from clause (iii)(b) of the second preceding paragraph; (viii) loans or
advances to employees of the Issuer or any Restricted Subsidiary made in the
ordinary course of business, including to fund the purchase of Capital Stock of
the Issuer (provided that any proceeds from such purchase are excluded from
clause (iii)(b) of the second preceding paragraph to the extent such loan or
advance is not reimbursed) in an amount not to exceed $2.0 million at any time
outstanding; (ix) Investments constituting Restricted Payments in (1) joint
ventures formed to provide services in furtherance of an Internet Service
Business of the Issuer and the ISPs or (2) other persons engaged principally in
an Internet Service Business in an aggregate amount not to exceed $30.0 million
outstanding at any time, provided that no more than $15.0 million of Investments
made pursuant to the preceding clause (1) shall be outstanding at any time; and
(x) cash payments in lieu of fractional shares pursuant to any warrant, option
or other similar agreement.
    
 
     In determining whether or not the net cash proceeds of a sale of Capital
Stock is "substantially concurrent" for purposes of clause (iv)(b)(x) of the
preceding paragraph, if such net cash proceeds are deposited in escrow with a
third party, free and clear of any Lien (other than the Lien of the escrow
agent), to be applied for purposes directed by the Issuer and such net cash
proceeds are excluded from clause (iii)(b) of the first paragraph above, then
the application of such net cash proceeds as set forth in such clause (iv)(b)(x)
shall be deemed "substantially concurrent" if they are subsequently released for
immediate application as contemplated by such clause (iv)(b)(x). In no event
shall a Restricted Payment made on the basis of consolidated financial
statements prepared in good faith in accordance with GAAP be subject to
rescission or constitute a Default by reason of any requisite subsequent
restatement of such financial statements which would have made such Restricted
Payment prohibited at the time that it was made.
 
     In determining the amount of Restricted Payments permissible under this
covenant, amounts expended pursuant to clauses (i), (iv)(a), (iv)(b)(y), (v),
(vi) and (ix) (to the extent remaining outstanding) above shall be included,
without duplication, as Restricted Payments.

     Limitation on Liens Securing Certain Indebtedness. The 1997 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 (i) any of 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 1997 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 the Issuer that
is not Subordinated Indebtedness, unless the 1997 Notes are equally and ratably
secured with the Liens securing such other Indebtedness, except, in the case of
this clause (y), Permitted Liens, or (ii) the Escrow Account.
    
 
   
     Limitation on Business. The 1997 Indenture provides that the Issuer will
not, and will not permit any of the Restricted Subsidiaries to, engage in a
business which is not substantially an Internet Service Business.
    
 
   
     Limitation on Certain Guarantees and Indebtedness of Restricted
Subsidiaries. The 1997 Indenture provides that the Issuer will not permit any
Restricted Subsidiary, directly or indirectly, to assume, guarantee or in any
other manner become liable with respect to (i) any Subordinated Indebtedness or
(ii) any Indebtedness of the Issuer that is not Subordinated Indebtedness (other
than, in the case of this clause (ii), Indebtedness under any Permitted Credit
Facility to the extent constituting Permitted Indebtedness), unless, in each
case, such Restricted Subsidiary simultaneously executes and delivers a
supplemental indenture providing for the guarantee of payment of the 1997 Notes
by such Restricted Subsidiary on a basis senior to any such Subordinated
Indebtedness or pari passu with any such other Indebtedness referred to in
clause (ii), as the case may be. Each guarantee created pursuant to such
provisions is referred to as a "Guarantee" and the issuer of each such
Guarantee, so long as the Guarantee remains outstanding, is referred to as a
"Guarantor."
    
 
     Notwithstanding the foregoing, in the event of the unconditional release of
any Guarantor from its obligations in respect of the Indebtedness which gave
rise to the requirement that a Guarantee be given, such Guarantor shall be
released from all obligations under its Guarantee. In addition, upon any sale or
disposition (by merger or otherwise) of any 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 Restricted Subsidiaries which is otherwise in
compliance with the terms of the Indenture and as a result of which such
Guarantor ceases to be a Restricted Subsidiary of the Issuer, such Guarantor
will be deemed to be automatically and unconditionally released from all
obligations under its Guarantee; provided that each such Guarantor is sold or
disposed of in accordance with the "Disposition of Proceeds of Asset Sales"
covenant.
 
   
     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 1997 Notes then outstanding at a purchase price equal to 101%
of the principal amount thereof on any Change of Control Payment Date, plus
accrued and unpaid interest, if any, to such Change of Control Payment Date.
Notice of a Change of Control Offer shall be given to holders of 1997 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 1997
Indenture does not contain provisions that permit the holders of the 1997 Notes
to require that the Company repurchase or redeem the 1997 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 1997 Notes
that might be delivered by holders of 1997 Notes seeking to accept the Change of
Control Offer. The Issuer shall not be required to make a Change of Control
Offer following a Change of Control if a third party makes the Change of Control
Offer in the manner, at the times and otherwise in compliance with the
requirements applicable to a Change of Control Offer made by the Issuer and
purchases all 1997 Notes validly tendered and not withdrawn under such Change of
Control Offer.
    
 
                                       83
<PAGE>   91
 
     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.
 
   
     The phrase "all or substantially all" of the assets of the Company, as used
in the definition of "Change of Control," will likely be interpreted under
applicable state law and will be dependent upon particular facts and
circumstances. Although there is a developing body of case law interpreting the
phrase "substantially all," there is no precise established definition of the
phrase under applicable law. As a result, there may be a degree of uncertainty
in ascertaining whether a sale or transfer of "all or substantially all" of the
assets of the Company has occurred.
    
 
   
     Limitation on Dividends and Other Payment Restrictions Affecting Restricted
Subsidiaries. The 1997 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 (a) 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, (b) pay any
Indebtedness owed to the Issuer or any Restricted Subsidiary, (c) make any
Investment in the Issuer or any Restricted Subsidiary or (d) transfer any of its
properties or assets to the Issuer or to any Restricted Subsidiary, except for
(in each case except as otherwise noted in the following clause (ii)), (i) any
encumbrance or restriction in existence on the Issue Date, (ii) any encumbrance
or restriction existing under agreements relating to an Investment in an ISP
(which in the case of clause (a) and (b) shall not be permitted in the case of
ISPs that are Restricted Subsidiaries) to the extent consistent with past
practice, (iii) customary non-assignment provisions, (iv) any encumbrances or
restriction pertaining to an asset subject to a Lien to the extent set forth in
the security documentation governing such Lien, (v) 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, (vi) any
encumbrance or restriction existing under any agreement that refinances or
replaces an agreement containing a restriction permitted by clause (v) above;
provided that the terms and conditions of any such encumbrance or restriction
are not materially less favorable to the holders of 1997 Notes than those under
or pursuant to the agreement being replaced or the agreement evidencing the
Indebtedness refinanced, (vii) 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 and (viii) 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
Permitted Credit Facility; provided that the provisions of such agreement permit
the payment of interest and principal and mandatory repurchases pursuant to the
terms of the 1997 Indenture and the 1997 Notes and other Indebtedness that is
solely an obligation of the Issuer, but, provided, further, that such agreement
may nevertheless contain customary net worth, leverage, invested capital and
other financial covenants, customary covenants regarding the merger of or sale
of all or any substantial part of the assets of the Issuer or any Restricted
Subsidiary, customary restrictions on transactions with affiliates, and
customary subordination provisions governing Indebtedness owed to the Issuer or
any Restricted Subsidiary.
    
 
   
     Disposition of Proceeds of Asset Sales. The 1997 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 75% 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 liabilities (other than Subordinated
Indebtedness or Indebtedness of a Restricted Subsidiary that would not
constitute Restricted Subsidiary Indebtedness) that are assumed by the
transferee of any such assets pursuant to an agreement that unconditionally
releases the Issuer or such Restricted Subsidiary from further liability
("assumed liabilities") 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 received). The Issuer or the applicable Restricted Subsidiary, as the case
may be, may (i) apply the Net Cash Proceeds from such Asset
    
 
                                       84
<PAGE>   92
 
Sale within 365 days of the receipt thereof to repay an amount of Indebtedness
(other than Subordinated Indebtedness) of the Issuer in an amount not exceeding
the Other Senior Debt Pro Rata Share and elect to permanently reduce the amount
of the commitments thereunder by the amount of the Indebtedness so repaid, (ii)
apply the Net Cash Proceeds from such Asset Sale to repay any Restricted
Subsidiary Indebtedness and elect to permanently reduce the commitments
thereunder by the amount of the Indebtedness so repaid or (iii) apply such Net
Cash Proceeds within 365 days thereof, to an investment in properties and assets
that will be used in an Internet Service Business (or in Capital Stock and other
securities of any person that will become a Restricted Subsidiary as a result of
such investment to the extent such person owns properties and assets that will
be used in an Internet Service Business) of the Issuer or any Restricted
Subsidiary ("Replacement Assets"). Any Net Cash Proceeds from any Asset Sale
that are neither used to repay, and permanently reduce the commitments under,
any Restricted Subsidiary Indebtedness as set forth in clause (ii) of the
preceding sentence or invested in Replacement Assets within the 365-day period
as set forth in clause (iii) shall constitute "Excess Proceeds." Any Excess
Proceeds not used as set forth in clause (i) of the second preceding sentence
shall constitute "Offer Excess Proceeds" subject to disposition as provided
below.
 
   
     When the aggregate amount of Offer Excess Proceeds equals or exceeds $10.0
million, the Issuer shall make an offer to purchase (an "Asset Sale Offer"),
from all holders of the 1997 Notes, that aggregate principal amount of 1997
Notes as can be purchased by application of such Offer Excess Proceeds at a
price in cash equal to 100% of the principal amount thereof on any purchase
date, plus accrued and unpaid interest, if any, to any purchase date. 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 principal amount of
1997 Notes tendered pursuant to an Asset Sale Offer is less than the Offer
Excess Proceeds, the Issuer or any Restricted Subsidiary may use such deficiency
for general corporate purposes. If the principal amount of 1997 Notes validly
tendered and not withdrawn by holders thereof exceeds the amount of 1997 Notes
which can be purchased with the Offer Excess Proceeds, 1997 Notes to be
purchased will be selected on a pro rata basis. Upon completion of such Asset
Sale Offer, the amount of Offer Excess 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 Preferred Stock by Restricted
Subsidiaries. The 1997 Indenture provides that the Issuer (i) will not permit
any Restricted Subsidiary to issue any Preferred Stock (other than to the Issuer
or a Restricted Subsidiary) and (ii) will not permit any person (other than the
Issuer or a Restricted Subsidiary) to own any Preferred Stock of any Restricted
Subsidiary.
    
 
   
     Limitation on Transactions with Affiliates. The 1997 Indenture provides
that the Issuer will not, and will not permit, cause or suffer any Restricted
Subsidiary to, conduct any business or enter into any 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 (other than Affiliates of a
Restricted Subsidiary that are not also Affiliates of the Issuer or any Wholly
Owned Restricted Subsidiary) or any beneficial holder of 10% or more of the
Common Stock of the Issuer or any officer or director of the Issuer (each, an
"Affiliate Transaction"), unless the terms of the Affiliate Transaction are set
forth in writing, and are fair and reasonable to the Issuer or such Restricted
Subsidiary, as the case may be. Each Affiliate Transaction involving aggregate
payments or other Fair Market Value in excess of $1.0 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. In addition to the foregoing, each
Affiliate Transaction involving aggregate consideration of $5.0 million or more
shall be approved by a majority of the Disinterested Directors; provided that,
in lieu of such approval by the Disinterested Directors, the Issuer may obtain a
written opinion from an Independent Financial Advisor stating that the terms of
such Affiliate Transaction to the Issuer or the Restricted Subsidiary, as the
case may be, are fair from a financial point of view. 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 fair and reasonable to the Issuer and the
Restricted Subsidiaries, as the case may be, and, therefore, shall be permitted
under this covenant.
    
                                       85
<PAGE>   93
 
     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, (ii) transactions pursuant
to agreements and arrangements existing on the Issue Date, (iii) transactions
among any of the Issuer or the Restricted Subsidiaries, on the one hand, and any
of the ISPs, on the other hand, provided that (a) such transactions are in the
ordinary course of business and are related to or in furtherance of an Internet
Service Business and (b) no 10% or more beneficial shareholder of Common Stock
of the Issuer or officer or director of the Issuer shall beneficially own any
Capital Stock of such ISP, (iv) dividends paid by the Issuer pursuant to and in
compliance with the covenant "Limitation on Restricted Payments," (v) customary
directors' fees, indemnification and similar arrangements, consulting fees,
employee salaries bonuses, employment agreements and arrangements, compensation
or employee benefit arrangements or legal fees, (vi) transactions contemplated
by any of the Permitted Affiliate Agreements as in effect on the Issue Date and
(vii) grants of customary registration rights with respect to securities of the
Issuer.
 
     The Issuer is required to use, or to cause each Restricted Subsidiary to
use, its commercially reasonable best efforts to ensure that each person in
which the Issuer or a Restricted Subsidiary makes an Investment that is an ISP
at the time of the Investment at all times thereafter continues to meet the
conditions and requirements of the definition of "ISP" in all material respects.
 
   
     Reports. The 1997 Indenture provides that, for periods prior to the fiscal
quarter ending June 30, 1998, the Issuer shall furnish without cost to each
holder of 1997 Notes and file with the Trustee (i) within 135 days after the end
of each fiscal year of the Issuer, (x) audited year-end consolidated financial
statements (including a balance sheet, income statement and statement of changes
of cash flow) prepared in accordance with GAAP and substantially in the form
included in this Prospectus, (y) the information described in Item 303 of
Regulation S-K under the Securities Act with respect to such period and (z) all
pro forma and historical financial information in respect of any significant
transaction consummated more than 60 days prior to the date such information is
furnished (and any other transaction for which such information is available at
such time) to the extent such financial information would be required in a
filing on Form 10-K with the SEC at such time; and (ii) within 60 days after the
end of each of the first three fiscal quarters of each fiscal year of the
Issuer, (x) unaudited quarterly consolidated financial statements (including a
balance sheet, income statement and statement of changes of cash flows) prepared
in accordance with GAAP and substantially in the form included in this
Prospectus, (y) the information described in Item 303 of Regulation S-K under
the Securities Act with respect to such period and (z) all pro forma and
historical financial information in respect of any significant transaction
consummated more than 60 days prior to the date such information is furnished
(and any other transaction for which such information is available at such time)
to the extent such financial information would be required in a filing on Form
10-Q with the SEC at such time. Whether or not the Issuer has a class of
securities registered under the Exchange Act, the Issuer shall furnish without
cost to each holder of 1997 Notes and file with the Trustee and file with the
SEC, (a) beginning with the fiscal quarter ending June 30, 1998 (i) within the
applicable time period required under the Exchange Act, after the end of each
fiscal year of the Issuer, the information required by Form 10-K (or any
successor form thereto) under the Exchange Act with respect to such period and
(ii) within the applicable time period required under the Exchange Act after the
end of each of the first three fiscal quarters of each fiscal year of the
Issuer, the information required by Form 10-Q (or any successor form thereto)
under the Exchange Act with respect to such period and (b) from and after August
15, 1998, any current reports on Form 8-K (or any successor forms) required to
be filed under the Exchange Act. Prior to such time as the Issuer shall file
with the SEC its first report on either of Form 10-K or Form 10-Q under the
Exchange Act, the Issuer shall telephonically make its executive officers
available to holders of 1997 Notes upon 10-days advance written request of
holders of at least 10% of the aggregate principal amount of 1997 Notes
outstanding at the time of such request; provided that holders of 1997 Notes may
make only one such request per fiscal quarter.

<PAGE>   94
 
   
     Limitation on Designations of Unrestricted Subsidiaries. The 1997 Indenture
provides that the Issuer will not designate any Subsidiary of the Issuer (other
than a newly created Subsidiary in which no Investment has previously been made)
as an "Unrestricted Subsidiary" under the 1997 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 a Permitted Investment or an Investment made
     pursuant to clause (vii) or (ix) of the third paragraph of the covenant
     "Limitation on Restricted Payments," immediately after giving effect to
     such Designation, the Issuer would be able to incur $1.00 of Indebtedness
     under the proviso of the covenant "Limitation on Additional Indebtedness";
     and
 
   
          (c) the Issuer would not be prohibited under the 1997 Indenture from
     making an Investment at the time of Designation (assuming the effectiveness
     of such Designation) in an amount (the "Designation Amount") equal to the
     Fair Market Value of the net Investment of the Issuer or any other
     Restricted Subsidiary 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 1997 Indenture in
the Designation Amount. The 1997 Indenture further provides that neither the
Issuer nor any Restricted Subsidiary shall at any time (x) provide a guarantee
of, or similar credit support to, any Indebtedness of any Unrestricted
Subsidiary (including of any undertaking, agreement or instrument evidencing
such Indebtedness); provided that the Issuer may pledge Capital Stock or
Indebtedness of any Unrestricted Subsidiary on a nonrecourse basis such that the
pledgee has no claim whatsoever against the Issuer other than to obtain such
pledged property, (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 permitted under the covenants
"Limitation on Restricted Payments" and "Limitation on Transactions with
Affiliates."
    
 
   
     The 1997 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 1997
     Indenture.
    
 
     All Designations and Revocations must be evidenced by Board Resolutions
delivered to the Trustee certifying compliance with the foregoing provisions.
 
   
     Limitation on Status as Investment Company. The 1997 Indenture provides
that the Issuer will not, and will not permit any of its Subsidiaries or
controlled 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.
    
 
   
     Ratings of the 1997 Notes. The 1997 Indenture provides that the Issuer will
use its best efforts to obtain a rating for the 1997 Notes from each of Moody's
and S&P within 18 months of the Issue Date. A rating, if
    
 
                                       87

obtained, is not a recommendation to buy, sell or hold securities, is subject to
revision or withdrawal at any time by the assigning entity and should be
evaluated independently of any other rating.
 
CONSOLIDATION, MERGER, SALE OF ASSETS, ETC.
 
   
     The 1997 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 shall expressly assume all of the
obligations of the Issuer under the 1997 Notes and the 1997 Indenture, and
shall, if required by law to effectuate such assumption, 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 1997 Notes and the 1997 Indenture), as the
case may be, would be able to incur $1.00 of Indebtedness under the proviso of
the covenant "Limitation on Additional Indebtedness"; provided that, in the case
of any transaction or series of transactions comprised solely of one or more
Rollups, this clause (c) shall be deemed satisfied if the Issuer or the
surviving entity and the Restricted Subsidiaries would have been able to incur
all of their outstanding Indebtedness as Permitted Indebtedness; (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 stating that such transaction or series of
transactions, and, if a supplemental indenture is required in connection with
such transaction or series of transactions to effectuate such assumption, such
supplemental indenture complies with this covenant and that all conditions
precedent in the 1997 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 continuing 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 1997 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 1997
Indenture and the 1997 Notes.
    
 
   
     The 1997 Indenture provides that for all purposes of the 1997 Indenture and
the 1997 Notes (including the provision of this covenant and the covenants
"Limitation on Additional Indebtedness," "Limitation on Restricted Payments" and
"Limitation on Liens"), 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 "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.

     or
    
 
          (v) failure to perform any term, covenant, condition or provision of
     one or more classes or issues of Indebtedness in an aggregate principal
     amount of $7.5 million or more under which the Issuer or a Material

     already due and payable in full or (b) such failure results in the
     acceleration of the maturity of such Indebtedness; or
 
          (vi) any holder of at least $7.5 million in aggregate principal amount
     of Indebtedness of the Issuer or any Material Restricted Subsidiary shall
     commence judicial proceedings or take any other action to foreclose upon,

     remains in effect; or
 
          (vii) one or more judgments, orders or decrees for the payment of

     which a stay of enforcement of such judgment or order, by reason of pending
     appeal or otherwise, shall not be in effect; or
 
          (viii) certain events of bankruptcy, insolvency, reorganization,
     administration or similar proceedings with respect to the Issuer or any
     Material Restricted Subsidiary shall have occurred; or

     Agreement is invalid or unenforceable.
 
   
     If an Event of Default (other than an Event of Default specified in clause
(viii) above with respect to the Issuer) occurs and is continuing, then the
Trustee or the holders of at least 25% in principal amount of the outstanding
1997 Notes may, by written notice, and the Trustee upon the request of the
holders of not less than 25% in principal amount of the outstanding 1997 Notes
shall, declare the principal amount of, premium (if any) on, and any accrued and
unpaid interest on, all outstanding 1997 Notes to be immediately due and payable
and upon any such declaration such amounts shall become immediately due and
payable. If an Event of Default specified in clause (viii) above with respect to
the Issuer occurs and is continuing, then the principal amount of, premium (if
any) on, and any accrued and unpaid interest on, all outstanding 1997 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.
    
 
                                       89
<PAGE>   97
 
   
     After a declaration of acceleration, the holders of a majority in aggregate
principal amount of outstanding 1997 Notes may, by notice to the Trustee,
rescind such declaration of acceleration if all existing Events of Default,
other than nonpayment of the principal of, premium (if any) on, and any accrued
and unpaid interest on, the 1997 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 of the outstanding 1997 Notes also have the right
to waive past defaults under the 1997 Indenture, except a default in the payment
of principal of, premium (if any) on, or any interest on, any outstanding Note,
or in respect of certain covenants or a provisions that cannot be modified or
amended without the consent of all holders of 1997 Notes.
    
 
   
     No holder of any of the 1997 Notes has any right to institute any
proceeding with respect to the 1997 Indenture or any remedy thereunder, unless
the holders of at least 25% in principal amount of the outstanding 1997 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 of the
outstanding 1997 Notes. Such limitations do not apply, however, to a suit
instituted by a holder of a 1997 Note for the enforcement of the payment of the
principal of, premium (if any) on, or any accrued and unpaid interest on, such
Note on or after the respective due dates expressed in such 1997 Note.
    
 
   
     During the existence of an Event of Default, the Trustee is required to
exercise such rights and powers vested in it under the 1997 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 1997 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 1997 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 of the outstanding 1997 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 1997 Indenture provides that the Trustee will, within 45 days after the
occurrence of any Default, give to the holders of the 1997 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 1997 Indenture.
    
 
DEFEASANCE
 
   
     The Issuer may at any time terminate all of its obligations with respect to
the 1997 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 1997 Notes, to replace mutilated, destroyed, lost or
stolen 1997 Notes as required by the 1997 Indenture and to maintain agencies in
respect of 1997 Notes. The Issuer may at any time terminate its obligations
under certain covenants set forth in the 1997 Indenture, some of which are
described under "-- Certain Covenants" above, and any omission to comply with
such obligations shall not constitute a Default with respect to the 1997 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 1997 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 principal of, and
premium, if any, and interest on the 1997 Notes to redemption or maturity and
comply with certain other conditions, including the delivery of a legal opinion
as to certain tax matters.

     The 1997 Indenture will be discharged and will cease to be of further
effect (except as to surviving rights or registration of transfer or exchange of
1997 Notes) as to all outstanding 1997 Notes when either (a) all such 1997 Notes
theretofore authenticated and delivered (except lost, stolen or destroyed 1997
Notes that have been replaced or paid and 1997 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 1997 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 1997 Notes not
theretofore delivered to the Trustee for cancellation, for principal amount,
premium, if any, and accrued interest to the date of such deposit; (ii) the
Issuer has paid all sums payable by it under the 1997 Indenture; and (iii) the
Issuer has delivered irrevocable instructions to the Trustee to apply 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, when authorized by resolutions of the Board,
and the Trustee, without the consent of the holders of the 1997 Notes, may
amend, waive or supplement the 1997 Indenture or the 1997 Notes for certain
specified purposes, including, among other things, curing ambiguities, defects
or inconsistencies, maintaining the qualification of the 1997 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 1997 Indenture
and the 1997 Notes may be made by the Issuer and the Trustee by supplemental
indenture with the consent of the holders of not less than a majority of the
aggregate principal amount of the outstanding 1997 Notes; provided that no such
modification or amendment may, without the consent of the holder of each
outstanding 1997 Note affected thereby, (i) reduce the principal amount of,
change the fixed maturity of, or alter the redemption provisions of, the 1997
Notes, (ii) change the currency in which any 1997 Notes or amounts owing thereon

                         DESCRIPTION OF THE 1998 NOTES
    
 
   
     Set forth below is a summary of certain provisions of the New 1998 Notes.
The New 1998 Notes will be issued under the 1998 Indenture between the Issuer
and the Trustee. A copy of the Indenture may be obtained upon request from the
Issuer, 8005 South Chester Street, Suite 200, Englewood, Colorado 80112;
attention: General Counsel; telephone: (303) 645-1900.
    
 
   
     Except as otherwise indicated below, the following summary applies to both
the Old 1998 Notes and the New 1998 Notes. As used herein, the term "1998 Notes"
means the Old 1998 Notes and the New 1998 Notes, unless otherwise indicated.
    
 
   
     The form and terms, of the New 1998 Notes will be identical in all material
respects to the form and terms of the Old 1998 Notes, except that the New 1998
Notes will be registered under the Securities Act, and therefore such New 1998
Notes will not be subject to certain transfer restrictions and, registration
rights applicable to the Old 1998 Notes. See "The Exchange Offers."
    
 
   
     The 1998 Notes are issued under the 1998 Indenture, a copy of the form of
which is available upon request. The 1998 Indenture is 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 1998 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 1998 Indenture,
including the definitions of certain terms therein and those terms made a part
of the 1998 Indenture by reference to the Trust Indenture Act, as in effect on
the date of the 1998 Indenture. The definitions of certain capitalized terms
used in the following summary are set forth below under "Certain Definitions."
    
 
GENERAL
 
   
     The 1998 Notes are general senior obligations of the Issuer. The 1998 Notes
have been 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 1998 Notes are payable, and the 1998 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 1998 Notes, except in certain circumstances for any tax or
other governmental charge that may be imposed in connection therewith.
    
 
MATURITY, INTEREST AND PRINCIPAL
 
   
     The 1998 Notes are limited to $175,000,000 aggregate principal amount and
will mature on April 1, 2005. The Issuer will not be required to make any
mandatory sinking fund payments in respect of the 1998 Notes. Interest on the
1998 Notes will accrue at a rate of 10 3/8% per annum and be payable in cash
semi-annually in arrears on each April 1 and October 1 (each, an "Interest
Payment Date"), commencing October 1, 1998, to registered holders of 1998 Notes,
on the March 15 or September 15, as the case may be, immediately preceding such
Interest Payment Date. Interest on the 1998 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 the Issue Date.
Cash 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 and/or premium
(whether upon redemption or otherwise), cash interest will accrue on the amount
in default at the rate of interest borne by the 1998 Notes. Interest on overdue
principal and premium and, to the extent permitted by law, on overdue
installments of interest will accrue at the rate of interest borne by the 1998
Notes.
    
 
   
REDEMPTION
    
 
   
     Optional Redemption.  The 1998 Notes are redeemable, at the option of the
Issuer, in whole or in part, on or after April 1, 2002 upon not less than 30 nor
more than 60 days' written notice at the redemption prices (expressed as
percentages of principal amount) set forth below, plus accrued and unpaid
interest thereon, if
    
 
                                       104

any, to the applicable redemption date, if redeemed during the twelve-month
period beginning on April 1 of each of the years indicated below:

2003........................................................     102.594%

</TABLE>
 
   
     Notwithstanding the foregoing, in the event that after the Issue Date and
prior to April 1, 2001 the Issuer issues, in one or more transactions, Capital
Stock (other than Disqualified Stock) of the Issuer to WorldCom or one or more
Strategic Equity Investors or in any Public Equity Offering for aggregate gross
cash proceeds of $50.0 million or more (an "Equity Sale"), the Issuer may
redeem, at its option, up to a maximum of 35% of the initially outstanding
aggregate principal amount of 1998 Notes from the net proceeds thereof at a
redemption price equal to 110.375% of the principal amount of the 1998 Notes,
together with accrued and unpaid interest to the date of redemption; provided
that not less than $113.75 million aggregate principal amount of 1998 Notes is
outstanding following such redemption. Any such redemption may only be effected
once and must be effected upon not less than 30 nor more than 60 days' notice
given within 180 days after such Equity Sale.
    
 
   
     Selection; Effect of Redemption Notice.  In the case of a partial
redemption, selection of the 1998 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 an
Equity Sale shall be made on a pro rata basis or on as nearly a pro rata basis
as practicable (subject to DTC procedures). No 1998 Notes of a principal amount
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 1998 Notes to be redeemed at its registered
address. If any 1998 Note is to be redeemed in part only, the notice of
redemption that relates to such 1998 Note shall state the portion of the
principal amount thereof to be redeemed. A new 1998 Note in a principal amount
equal to the unredeemed portion thereof will be issued in the name of the holder
thereof upon surrender for cancellation of the original 1998 Note. Upon giving
of a redemption notice, interest on 1998 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 1998 Notes will
cease to be outstanding.
    
 
RANKING
 
   
     The indebtedness of the Issuer evidenced by the 1998 Notes ranks senior in
right of payment to all subordinated indebtedness of the Issuer and pari passu
in right of payment with all other existing and future unsubordinated
indebtedness of the Issuer including the 1997 Notes.
    
 
   
     The Issuer is a holding company with limited assets and no business
operations of its own. The Issuer operates its business through its
subsidiaries. Any right of the Issuer and its creditors, including holders of
the 1998 Notes, to participate in the assets of any of the Issuer's subsidiaries
upon any liquidation or administration of any such subsidiary will be subject to
the prior claims of the subsidiary's creditors, including trade creditors. As of
December 31, 1997, on a pro forma basis after giving effect to the proposed IPO,
there would have been approximately $9.6 million of secured long-term
indebtedness outstanding to which holders of 1998 Notes would have been
effectively subordinated in right of payment and approximately $7.0 million of
subsidiary indebtedness to which holders of 1998 Notes would have been
structurally subordinated. In addition, the Bank Facility is secured by certain
assets, including the equity of the ISPs that Verio owns currently or may own in
the future, and thus the 1998 Notes are effectively subordinated to the Bank
Facility to the extent of the value of such assets. For a discussion of certain
adverse consequences of the Issuer being a holding company and of the terms of
potential future indebtedness of the Issuer and its subsidiaries, see "Risk
Factors -- Holding Company Structure and Need to Access Subsidiary Cash Flows."

CERTAIN COVENANTS
 
   
     Set forth below are certain covenants that are contained in the 1998
Indenture.

the Issuer will not, and will not permit any Restricted Subsidiary to, directly
or indirectly, incur any Indebtedness (including any Acquired Indebtedness),
except for Permitted Indebtedness (including Acquired Indebtedness to the extent
it would constitute Permitted Indebtedness); provided, however, that (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 ratio
of Total Consolidated Indebtedness to Consolidated Annualized Pro Forma
Operating Cash Flow would be less than 6.0 to 1.0.
    
 
   
     Limitation on Restricted Payments.  The 1998 Indenture provides that the
Issuer will not, and will not permit any of the Restricted Subsidiaries to,

     aggregate amount of all Restricted Payments declared or made on or after
     the Issue Date and all Designation Amounts does not exceed an amount equal
     to the sum of, without duplication, (a) 50% of the Consolidated Net Income
     of the Issuer accrued on a cumulative basis during the period beginning on
     January 1, 1998 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), 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 issue and

     exchange for, Indebtedness of the 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 (except for

     below, and (2) pursuant to clauses (viii) or (ix) of the second following
     paragraph), 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, plus (f) an amount equal to the
     amount of any Investment constituting a Restricted Payment made after the
     Issue Date in an ISP which has been included as a Restricted Payment under
     this clause (iii) pursuant to the last paragraph of this covenant to the
     extent such ISP thereafter (1) becomes a Wholly Owned Restricted Subsidiary
     or is merged with the Issuer or (2) is a New ISP that becomes a Restricted
     Subsidiary or is merged with the Issuer, less, in either such case, any
     amounts credited pursuant to the immediately preceding clause (d) in
     respect of any such Investment, minus (g) 50% of the principal amount of
     any Indebtedness incurred pursuant to clause (g) of the definition of
     "Permitted Indebtedness." For purposes of the preceding clauses (b)(y) and
     (c), as applicable, 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
 
                                       106
<PAGE>   114
 
     Indebtedness, options, warrants or rights plus the incremental amount
     received, if any, by the Issuer upon the conversion, exchange or exercise
     thereof.
 
     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 1998 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 Restricted 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 Restricted 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 1998 Notes; provided that any such net
cash proceeds are excluded from clause (iii)(b) of the second preceding
paragraph; (iv) (a) so long as no Default shall have occurred and be continuing,
Investments constituting Restricted Payments by the Issuer or any Restricted
Subsidiary in a New ISP or a person that becomes a New ISP as a result of such
Investment and (b) so long as no Default shall have occurred and be continuing,
Investments constituting Restricted Payments by the Issuer or any Restricted
Subsidiary in an Existing ISP (x) made out of the net cash proceeds of a
substantially concurrent sale of Capital Stock (other than Disqualified Stock)
of the Issuer (provided that any such proceeds are excluded from clause (iii)(b)
of the second preceding paragraph) or (y) such that the aggregate amount of all
Investments in Existing ISPs that are made after the Issue Date pursuant to this
subclause (b)(y) would not exceed $25.0 million in aggregate; (v) bonds, notes,
debentures or other securities received as a result of Asset Sales pursuant to
and in compliance with the covenant "Disposition of Proceeds of Asset Sales";
(vi) 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 Issuer or one of its Subsidiaries; provided that payments
shall not exceed $2.0 million in any fiscal year in the aggregate or $4.0
million in the aggregate during the term of the 1998 Notes; (vii) 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 a
substantially concurrent (1) capital contribution to the Issuer or (2) issue or
sale of Capital Stock (other than Disqualified Stock) of the Issuer (other than
to a Restricted Subsidiary of the Issuer); provided that any such proceeds are
excluded from clause (iii)(b) of the second preceding paragraph; (viii) loans or
advances to employees of the Issuer or any Restricted Subsidiary made in the
ordinary course of business, including to fund the purchase of Capital Stock of
the Issuer (provided that any proceeds from such purchase are excluded from
clause (iii)(b) of the second preceding paragraph to the extent such loan or
advance is not reimbursed) in an amount not to exceed $2.0 million at any time
outstanding; (ix) so long as no Default shall have occurred and be continuing,
Investments constituting Restricted Payments in joint ventures formed to provide
services in furtherance of an Internet Service Business of the Issuer and the
ISPs or other persons engaged principally in an Internet Service Business in an
aggregate amount not to exceed $30.0 million outstanding at any time; provided
that following the first Public Equity Offering resulting in aggregate gross
cash proceeds of $50.0 million or more to the Issuer, the aggregate amount of
Investments permitted pursuant to this clause (ix) shall be increased to an
aggregate amount not to exceed $50.0 million outstanding at any time; and (x)
cash payments in lieu of fractional shares pursuant to any warrant, option or
other similar agreement.
    
 
     In determining whether the receipt of net cash proceeds of a sale of
Capital Stock is "substantially concurrent" for purposes of clause (iv)(b)(x) of
the preceding paragraph, if such net cash proceeds are deposited in escrow with
a third party, free and clear of any Lien (other than the Lien of the escrow
agent), to be applied for purposes directed by the Issuer and such net cash
proceeds are excluded from clause (iii)(b) of
 
                                       107
<PAGE>   115
 
the first paragraph above, then the application of such net cash proceeds as set
forth in such clause (iv)(b)(x) shall be deemed "substantially concurrent" if
they are subsequently released for immediate application as contemplated by such
clause (iv)(b)(x). In no event shall a Restricted Payment made on the basis of
consolidated financial statements prepared in good faith in accordance with GAAP
be subject to rescission or constitute a Default by reason of any requisite
subsequent restatement of such financial statements which would have made such
Restricted Payment prohibited at the time that it was made.
 
     In determining the amount of Restricted Payments permissible under this
covenant, amounts expended pursuant to clauses (i), (iv)(a), (iv)(b)(y), (v),
(vi) and (ix) (to the extent remaining outstanding) above shall be included,
without duplication, as Restricted Payments.
 
   
     Limitation on Liens Securing Certain Indebtedness.  The 1998 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 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 1998 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 the Issuer that
is not Subordinated Indebtedness, unless the 1998 Notes are equally and ratably
secured with the Liens securing such other Indebtedness, except, in the case of
this clause (y), Permitted Liens.
    
 
   
     Limitation on Business.  The 1998 Indenture provides that the Issuer will
not, and will not permit any of the Restricted Subsidiaries to, engage in a
business which is not substantially an Internet Service Business.
    
 
   
     Limitation on Certain Guarantees and Indebtedness of Restricted
Subsidiaries.  The 1998 Indenture provides that the Issuer will not permit any
Restricted Subsidiary, directly or indirectly, to assume, guarantee or in any
other manner become liable with respect to (i) any Subordinated Indebtedness or
(ii) any Indebtedness of the Issuer that is not Subordinated Indebtedness (other
than, in the case of this clause (ii), Indebtedness under any Permitted Credit
Facility to the extent constituting Permitted Indebtedness), unless, in each
case, such Restricted Subsidiary simultaneously executes and delivers a
supplemental indenture providing for the guarantee of payment of the 1998 Notes
by such Restricted Subsidiary on a basis senior to any such Subordinated
Indebtedness or pari passu with any such other Indebtedness referred to in
clause (ii), as the case may be. Each guarantee created pursuant to such
provisions is referred to as a "Guarantee" and the issuer of each such
Guarantee, so long as the Guarantee remains outstanding, is referred to as a
"Guarantor."
    
 
     Notwithstanding the foregoing, in the event of the unconditional release of
any Guarantor from its obligations in respect of the Indebtedness which gave
rise to the requirement that a Guarantee be given, such Guarantor shall be
released from all obligations under its Guarantee. In addition, upon any sale or
disposition (by merger or otherwise) of any 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 Restricted Subsidiaries which is otherwise in
compliance with the terms of the Indenture and as a result of which such
Guarantor ceases to be a Restricted Subsidiary of the Issuer, such Guarantor
will be deemed to be automatically and unconditionally released from all
obligations under its Guarantee; provided that each such Guarantor is sold or
disposed of in accordance with the "Disposition of Proceeds of Asset Sales"
covenant.
 
   
     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 1998 Notes then outstanding at a purchase price equal to 101%
of the principal amount thereof on any Change of Control Payment Date, plus
accrued and unpaid interest, if any, to such Change of Control Payment Date.
Notice of a Change of Control Offer shall be given to holders of 1998 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.
    
 
                                       108
<PAGE>   116
 
   
     Except as described above with respect to a Change of Control, the 1998
Indenture does not contain provisions that permit the holders of the 1998 Notes
to require that the Issuer repurchase or redeem the 1998 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 1998 Notes
that might be delivered by holders of 1998 Notes seeking to accept the Change of
Control Offer. The Issuer shall not be required to make a Change of Control
Offer following a Change of Control if a third party makes the Change of Control
Offer in the manner, at the times and otherwise in compliance with the
requirements applicable to a Change of Control Offer made by the Issuer and
purchases all 1998 Notes validly tendered and not withdrawn under such Change of
Control Offer.
    
 
     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.
 
   
     The phrase "all or substantially all" of the assets of the Company, as used
in the definition of "Change of Control," will likely be interpreted under
applicable state law and will be dependent upon particular facts and
circumstances. Although there is a developing body of case law interpreting the
phrase "substantially all," there is no precise established definition of the
phrase under applicable law. As a result, there may be a degree of uncertainty
in ascertaining whether a sale or transfer of "all or substantially all" of the
assets of the Company has occurred.
    
 
   
     Limitation on Dividends and Other Payment Restrictions Affecting Restricted
Subsidiaries.  The 1998 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 (a) 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, (b) pay
any Indebtedness owed to the Issuer or any Restricted Subsidiary, (c) make any
Investment in the Issuer or any Restricted Subsidiary or (d) transfer any of its
properties or assets to the Issuer or to any Restricted Subsidiary, except for
(in each case except as otherwise noted in the following clause (ii)), (i) any
encumbrance or restriction in existence on the Issue Date, (ii) any encumbrance
or restriction existing under agreements relating to an Investment in an ISP
(which in the case of clause (a) and (b) shall not be permitted in the case of
ISPs that are Restricted Subsidiaries) to the extent consistent with past
practice, (iii) customary non-assignment provisions, (iv) any encumbrances or
restrictions pertaining to an asset subject to a Lien to the extent set forth in
the security documentation governing such Lien, (v) 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, (vi) any
encumbrance or restriction existing under any agreement that refinances or
replaces an agreement containing a restriction permitted by clause (v) above;
provided that the terms and conditions of any such encumbrance or restriction
are not materially less favorable to the holders of 1998 Notes than those under
or pursuant to the agreement being replaced or the agreement evidencing the
Indebtedness refinanced, (vii) 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 and (viii) 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
Permitted Credit Facility; provided that the provisions of such agreement permit
the payment of interest and principal and mandatory repurchases pursuant to the
terms of the 1998 Indenture and the 1998 Notes and other Indebtedness that is
solely an obligation of the Issuer, but, provided, further, that such agreement
may nevertheless contain customary net worth, leverage, invested capital and
other financial covenants, customary covenants regarding the merger of or sale
of all or any substantial part of the assets of the Issuer or any Restricted
Subsidiary, customary restrictions on transactions with affiliates, and
customary subordination provisions governing Indebtedness owed to the Issuer or
any Restricted Subsidiary.

     Disposition of Proceeds of Asset Sales.  The 1998 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 75% 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 liabilities (other than Subordinated
Indebtedness or Indebtedness of a Restricted Subsidiary that would not
constitute Restricted Subsidiary Indebtedness) that are assumed by the
transferee of any such assets pursuant to an agreement that unconditionally
releases the Issuer or such Restricted Subsidiary from further liability
("assumed liabilities") 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 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 an amount of Indebtedness (other than
Subordinated Indebtedness) of the Issuer in an amount not exceeding the Other
Senior Debt Pro Rata Share and elect to permanently reduce the amount of the
commitments thereunder by the amount of the Indebtedness so repaid, (ii) apply
the Net Cash Proceeds from such Asset Sale to repay any Restricted Subsidiary
Indebtedness and elect to permanently reduce the commitments thereunder by the
amount of the Indebtedness so repaid or (iii) apply such Net Cash Proceeds
within 365 days thereof, to an investment in properties and assets that will be
used in an Internet Service Business (or in Capital Stock and other securities
of any person that will become a Restricted Subsidiary as a result of such
investment to the extent such person owns properties and assets that will be
used in an Internet Service Business) of the Issuer or any Restricted Subsidiary
("Replacement Assets"). Any Net Cash Proceeds from any Asset Sale that are
neither used to repay, and permanently reduce the commitments under, any
Restricted Subsidiary Indebtedness as set forth in clause (ii) of the preceding
sentence or invested in Replacement Assets within the 365-day period as set
forth in clause (iii) shall constitute "Excess Proceeds." Any Excess Proceeds
not used as set forth in clause (i) of the second preceding sentence shall
constitute "Offer Excess Proceeds" subject to disposition as provided below.
    
 
   
     When the aggregate amount of Offer Excess Proceeds equals or exceeds $10.0
million, the Issuer shall make an offer to purchase (an "Asset Sale Offer"),
from all holders of the 1998 Notes, that aggregate principal amount of 1998
Notes as can be purchased by application of such Offer Excess Proceeds at a
price in cash equal to 100% of the principal amount thereof on any purchase
date, plus accrued and unpaid interest, if any, to any purchase date. 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 principal amount of
1998 Notes tendered pursuant to an Asset Sale Offer is less than the Offer
Excess Proceeds, the Issuer or any Restricted Subsidiary may use such deficiency
for general corporate purposes. If the principal amount of 1998 Notes validly
tendered and not withdrawn by holders thereof exceeds the amount of 1998 Notes
which can be purchased with the Offer Excess Proceeds, 1998 Notes to be
purchased will be selected on a pro rata basis. Upon completion of such Asset
Sale Offer, the amount of Offer Excess 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 Preferred Stock by Restricted
Subsidiaries.  The 1998 Indenture provides that the Issuer will not permit any
Restricted Subsidiary to issue any Preferred Stock (other than to the Issuer or
a Restricted Subsidiary).
    
 
   
     Limitation on Transactions with Affiliates.  The 1998 Indenture provides
that the Issuer will not, and will not permit, cause or suffer any Restricted
Subsidiary to, conduct any business or enter into any 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 (other than Affiliates of a
Restricted Subsidiary that are not also Affiliates of the Issuer or any Wholly
Owned Restricted Subsidiary) or any beneficial holder of 10% or more of the
Common Stock of the Issuer or any officer or director of the Issuer (each, an
"Affiliate Transaction"), unless the terms of the Affiliate Transaction are set
forth in writing, and are fair and reasonable to the Issuer or such Restricted
Subsidiary, as the case may be. Each Affiliate Transaction involving aggregate
payments or other Fair Market
    
                                       110
<PAGE>   118
 
Value in excess of $1.0 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. In addition to the foregoing, each Affiliate Transaction involving
aggregate consideration of $5.0 million or more shall be approved by a majority
of the Disinterested Directors; provided that, in lieu of such approval by the
Disinterested Directors, the Issuer may obtain a written opinion from an
Independent Financial Advisor stating that the terms of such Affiliate
Transaction to the Issuer or the Restricted Subsidiary, as the case may be, are
fair from a financial point of view. 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 fair and reasonable to the Issuer and the Restricted
Subsidiaries, as the case may be, 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, (ii) transactions pursuant
to agreements and arrangements existing on the Issue Date, (iii) transactions
related to the provision of internet services in the ordinary course of
business; provided that (x) such transactions are entered into on an arm's
length basis and are fair and reasonable to the Issuer or such Restricted
Subsidiary, as the case may be, and (y) in the good faith judgment of the Issuer
or the applicable Restricted Subsidiary, the Fair Market Value of the
consideration received by the Issuer or such Restricted Subsidiary, as the case
may be, reasonably approximates the Fair Market Value of the services provided,
(iv) dividends paid by the Issuer pursuant to and in compliance with the
covenant "Limitation on Restricted Payments," (v) customary directors' fees,
indemnification and similar arrangements, consulting fees, employee salaries
bonuses, employment agreements and arrangements, compensation or employee
benefit arrangements or legal fees, (vi) transactions contemplated by any of the
Permitted Affiliate Agreements as in effect on the Issue Date and (vii) grants
of customary registration rights with respect to securities of the Issuer.
 
   
     The Issuer is required to use, or to cause each Restricted Subsidiary to
use, its commercially reasonable best efforts to ensure that each person in
which the Issuer or a Restricted Subsidiary makes an Investment that is an ISP
at the time of the Investment continues to meet the conditions and requirements
of the definition of "ISP" in all material respects until such time as a Rollup
shall have occurred with respect to such ISP.
    
 
   
     Reports.  The 1998 Indenture provides that, for periods prior to the fiscal
quarter ending June 30, 1998, the Issuer shall furnish without cost to each
holder of 1998 Notes and file with the Trustee (i) within 135 days after the end
of each fiscal year of the Issuer, (x) audited year-end consolidated financial
statements (including a balance sheet, income statement and statement of changes
of cash flow) prepared in accordance with GAAP and substantially in the form
included in this Offering Memorandum, (y) the information described in Item 303
of Regulation S-K under the Securities Act with respect to such period and (z)
all pro forma and historical financial information in respect of any significant
transaction consummated more than 60 days prior to the date such information is
furnished (and any other transaction for which such information is available at
such time) to the extent such financial information would be required in a
filing on Form 10-K with the SEC at such time; and (ii) within 60 days after the
end of each of the first three fiscal quarters of each fiscal year of the
Issuer, (x) unaudited quarterly consolidated financial statements (including a
balance sheet, income statement and statement of changes of cash flows) prepared
in accordance with GAAP and substantially in the form included in this Offering
Memorandum, (y) the information described in Item 303 of Regulation S-K under
the Securities Act with respect to such period and (z) all pro forma and
historical financial information in respect of any significant transaction
consummated more than 60 days prior to the date such information is furnished
(and any other transaction for which such information is available at such time)
to the extent such financial information would be required in a filing on Form
10-Q with the SEC at such time. Whether or not the Issuer has a class of
securities registered under the Exchange Act, the Issuer shall furnish without
cost to each holder of 1998 Notes and file with the Trustee and file with the
SEC, (a) beginning with the fiscal quarter ending June 30, 1998 (i) within the
applicable time period required under the Exchange Act, after the end of each
fiscal year of the Issuer, the information required by Form 10-K
    
 
                                       111
<PAGE>   119
 
   
(or any successor form thereto) under the Exchange Act with respect to such
period and (ii) within the applicable time period required under the Exchange
Act after the end of each of the first three fiscal quarters of each fiscal year
of the Issuer, the information required by Form 10-Q (or any successor form
thereto) under the Exchange Act with respect to such period and (b) from and
after August 15, 1998, any current reports on Form 8-K (or any successor forms)
required to be filed under the Exchange Act. Prior to such time as the Issuer
shall file with the SEC its first report on either of Form 10-K or Form 10-Q
under the Exchange Act, the Issuer shall telephonically make its executive
officers available to holders of 1998 Notes upon 10-days advance written request
of holders of at least 10% of the aggregate principal amount of 1998 Notes
outstanding at the time of such request; provided that holders of 1998 Notes may
make only one such request per fiscal quarter.
    
 
   
     Limitation on Designations of Unrestricted Subsidiaries.  The 1998
Indenture provides that the Issuer will not designate any Subsidiary of the
Issuer (other than a newly created Subsidiary in which no Investment has
previously been made) as an "Unrestricted Subsidiary" under the 1998 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 a Permitted Investment or an Investment made
     pursuant to clause (vii) or (ix) of the third paragraph of the covenant
     "Limitation on Restricted Payments," immediately after giving effect to
     such Designation, the Issuer would be able to incur $1.00 of Indebtedness
     under the proviso of the covenant "Limitation on Additional Indebtedness";
     and
 
   
          (c) the Issuer would not be prohibited under the 1998 Indenture from
     making an Investment at the time of Designation (assuming the effectiveness
     of such Designation) in an amount (the "Designation Amount") equal to the
     Fair Market Value of the net Investment of the Issuer or any other
     Restricted Subsidiary 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 1998 Indenture in
the Designation Amount. The 1998 Indenture further provides that neither the
Issuer nor any Restricted Subsidiary shall at any time (x) provide a guarantee
of, or similar credit support to, any Indebtedness of any Unrestricted
Subsidiary (including of any undertaking, agreement or instrument evidencing
such Indebtedness); provided that the Issuer may pledge Capital Stock or
Indebtedness of any Unrestricted Subsidiary on a nonrecourse basis such that the
pledgee has no claim whatsoever against the Issuer other than to obtain such
pledged property, (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 permitted under the covenants
"Limitation on Restricted Payments" and "Limitation on Transactions with
Affiliates."
    
 
   
     The 1998 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 1998
     Indenture.

     Limitation on Status as Investment Company.  The 1998 Indenture provides
that the Issuer will not, and will not permit any of its Subsidiaries or
controlled 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 1998 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 shall expressly assume all of the
obligations of the Issuer under the 1998 Notes and the 1998 Indenture, and
shall, if required by law to effectuate such assumption, 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 1998 Notes and the 1998 Indenture), as the
case may be, would be able to incur $1.00 of Indebtedness under the proviso of
the covenant "Limitation on Additional Indebtedness"; provided that, in the case
of any transaction or series of transactions comprised solely of one or more
Rollups, this clause (c) shall be deemed satisfied if the Issuer or the
surviving entity and the Restricted Subsidiaries would have been able to incur
all of their outstanding Indebtedness as Permitted Indebtedness; (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 stating that such transaction or series of
transactions, and, if a supplemental indenture is required in connection with
such transaction or series of transactions to effectuate such assumption, such
supplemental indenture complies with this covenant and that all conditions
precedent in the 1998 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 continuing 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 1998 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 1998
Indenture and the 1998 Notes.
    
 
   
     The 1998 Indenture provides that for all purposes of the 1998 Indenture and
the 1998 Notes (including the provision of this covenant and the 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
    
 
                                       113
<PAGE>   121
 
Unrestricted Subsidiaries as provided pursuant to the covenant "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.

     above), and continuance of such default or breach for a period of 30 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 of the outstanding 1998 Notes (in each case, when such notice is
     deemed received in accordance with the 1998 Indenture); or
    
 
          (v) failure to perform any term, covenant, condition or provision of
     one or more classes or issues of Indebtedness in an aggregate principal
     amount of $7.5 million or more under which the Issuer or a Material
     Restricted Subsidiary is obligated, and either (a) such Indebtedness is
     already due and payable in full or (b) such failure results in the
     acceleration of the maturity of such Indebtedness; or
 
          (vi) any holder of at least $7.5 million in aggregate principal amount
     of Indebtedness 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
     $7.5 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
 
          (vii) one or more judgments, orders or decrees for the payment of
     money of $7.5 million or more, either individually or in the aggregate,
     shall be entered into against the Issuer or any Material Restricted
     Subsidiary or any of their respective properties and shall not be
     discharged and there shall have been a period of 60 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
 
          (viii) certain events of bankruptcy, insolvency, reorganization,
     administration or similar proceedings with respect to the Issuer or any
     Material Restricted Subsidiary shall have occurred.
 
   
     If an Event of Default (other than an Event of Default specified in clause
(viii) above with respect to the Issuer) occurs and is continuing, then the
Trustee or the holders of at least 25% in principal amount of the outstanding
1998 Notes may, by written notice, and the Trustee upon the request of the
holders of not less than 25% in principal amount of the outstanding 1998 Notes
shall, declare the principal amount of, premium (if any) on, and any accrued and
unpaid interest on, all outstanding 1998 Notes to be immediately due and payable
and upon any such declaration such amounts shall become immediately due and
payable. If an Event of Default specified in clause (viii) above with respect to
the Issuer occurs and is continuing, then the principal amount of, premium (if
any) on, and any accrued and unpaid interest on, all outstanding 1998 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.
    
 
                                       114
<PAGE>   122
 
   
     After a declaration of acceleration, the holders of a majority in aggregate
principal amount of outstanding 1998 Notes may, by notice to the Trustee,
rescind such declaration of acceleration if all existing Events of Default,
other than nonpayment of the principal of, premium (if any) on, and any accrued
and unpaid interest on, the 1998 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 of the outstanding 1998 Notes also have the right
to waive past defaults under the 1998 Indenture, except a default in the payment
of principal of, premium (if any) on, or any interest on, any outstanding Note,
or in respect of certain covenants or a provisions that cannot be modified or
amended without the consent of all holders of 1998 Notes.
    
 
   
     No holder of any of the 1998 Notes has any right to institute any
proceeding with respect to the 1998 Indenture or any remedy thereunder, unless
the holders of at least 25% in principal amount of the outstanding 1998 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 of the
outstanding 1998 Notes. Such limitations do not apply, however, to a suit
instituted by a holder of a 1998 Note for the enforcement of the payment of the
principal of, premium (if any) on, or any accrued and unpaid interest on, such
Note on or after the respective due dates expressed in such 1998 Note.
    
 
   
     During the existence of an Event of Default, the Trustee is required to
exercise such rights and powers vested in it under the 1998 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 1998 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 1998 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 of the outstanding 1998 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 1998 Indenture provides that the Trustee will, within 45 days after the
occurrence of any Default, give to the holders of the 1998 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 1998 Indenture.
    
 
DEFEASANCE
 
   
     The Issuer may at any time terminate all of its obligations with respect to
the 1998 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 1998 Notes, to replace mutilated, destroyed, lost or
stolen 1998 Notes as required by the 1998 Indenture and to maintain agencies in
respect of 1998 Notes. The Issuer may at any time terminate its obligations
under certain covenants set forth in the 1998 Indenture, some of which are
described under " -- Certain Covenants" above, and any omission to comply with
such obligations shall not constitute a Default with respect to the 1998 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 1998 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 principal of, and
premium, if any, and interest on the 1998 Notes to redemption or maturity and
comply with certain other conditions, including the delivery of a legal opinion
as to certain tax matters.

SATISFACTION AND DISCHARGE
 
   
     The 1998 Indenture will be discharged and will cease to be of further
effect (except as to surviving rights or registration of transfer or exchange of
1998 Notes) as to all outstanding 1998 Notes when either (a) all such 1998 Notes
theretofore authenticated and delivered (except lost, stolen or destroyed 1998
Notes that have been replaced or paid and 1998 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 1998 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 1998 Notes not
theretofore delivered to the Trustee for cancellation, for principal amount,
premium, if any, and accrued interest to the date of such deposit; (ii) the
Issuer has paid all sums payable by it under the 1998 Indenture; and (iii) the
Issuer has delivered irrevocable instructions to the Trustee to apply 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, when authorized by resolutions of the Board,
and the Trustee, without the consent of the holders of the 1998 Notes, may
amend, waive or supplement the 1998 Indenture or the 1998 Notes for certain
specified purposes, including, among other things, curing ambiguities, defects
or inconsistencies, maintaining the qualification of the 1998 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 1998 Indenture
and the 1998 Notes may be made by the Issuer and the Trustee by supplemental
indenture with the consent of the holders of not less than a majority of the
aggregate principal amount of the outstanding 1998 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 of, change
the fixed maturity of, or alter the redemption provisions of, the 1998 Notes,
(ii) change the currency in which any 1998 Notes or amounts owing thereon is
payable, (iii) reduce the percentage of the aggregate principal amount
outstanding of 1998 Notes which must consent to an amendment, supplement or
waiver or consent to take any action under the 1998 Indenture or the 1998 Notes,

with the terms of the 1998 Indenture.

                         BOOK-ENTRY; DELIVERY AND FORM
    
 
   
     Except as set forth under "-- Certificated Securities," each of the New
1997 Notes and the New 1998 Notes will be issued in the form of one Global New
Note. Each such Global New Note will be deposited with, or on behalf of, the
Depository and registered in the name of the Depository or its nominee. Except
as set forth below, each such Global New Note may be transferred, in whole and
not in part, only to the Depository or another nominee of the Depository.
    
 
   
     Investors may hold their beneficial interests in each such Global New Note
directly through the Depository if they have an account with the Depository or
indirectly through organizations which have accounts with the Depository.
    
 
   
     The Depository has advised the Issuer as follows: The Depository is a
limited purpose trust company organized under the laws of the State of New York,
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. The Depository
was created to hold securities of institutions that have accounts with the
Depository ("participants") and to facilitate the clearance and settlement of
securities transactions among its participants in such securities through
electronic book-entry changes in accounts of the participants, thereby
eliminating the need for physical movement of securities certificates. The
Depository's participants include securities brokers and dealers (which may
include the Initial Purchasers), banks, trust companies, clearing corporations
and certain other organizations. Access to the Depository's book-entry system is
also available to others such as banks, brokers, dealers and trust companies
that clear through or maintain a custodial relationship with a participant,
whether directly or indirectly.
    
 
   
     Upon the issuance of each such Global New Note, the Depository will credit,
on its book-entry registration and transfer system, the principal amount of the
applicable New Notes represented by such
    
 
                                       128
<PAGE>   136
 
   
Global New Note to the accounts of participants. Ownership of beneficial
interests in each such Global New Note will be limited to participants or
persons that may hold interests through participants. Ownership of beneficial
interests in each such Global New Note will be shown on, and the transfer of
those ownership interests will be effected only through records maintained by
the Depository (with respect to participants' interest) and such participants
(with respect to the owners of beneficial interests in the applicable Global New
Note other than participants). The laws of some jurisdictions may require that
certain purchasers of securities take physical delivery of such securities in
definitive form. Such limits and laws may impair the ability to transfer or
pledge beneficial interests in each such Global New Note.
    
 
   
     So long as the Depository, or its nominee, is the registered holder and
owner of a Global New Notes, the Depository or such nominee, as the case may be,
will be considered the sole legal owner and holder of the related New Notes for
all purposes of such New Notes and the 1997 Indenture or 1998 Indenture, as the
case may be. Except as set forth below, owners of beneficial interests in each
Global New Note will not be entitled to have the New Notes represented by the
applicable Global New Note registered in their names, will not receive or be
entitled to receive physical delivery of certificated New Notes in definitive
form and will not be considered to be the owners or holders of any New Notes
under the applicable Global New Note. The Issuer understands that under existing
industry practice, in the event an owner of a beneficial interest in a Global
New Note desires to take any action that the Depository, as the holder of the
Global New Notes is entitled to take, the Depository would authorize the
participants to take such action, and that the participants would authorize
beneficial owners owning through such participants to take such action or would
otherwise act upon the instructions of beneficial owners owning through them.
    
 
   
     Payment of principal of and interest on New Notes represented by a Global
New Note registered in the name of and held by the Depository or its nominee
will be made to the Depository or its nominee, as the case may be, as the
registered owner and holder of the applicable Global New Note.
    
 
   
     The Company expects that the Depository or its nominee, upon receipt of any
payment of principal of or interest on a Global New Note, will credit
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of the applicable Global
New Note as shown on the records of the Depository or its nominee. The Issuer
also expects that payments by participants to owners of beneficial interests in
a Global New Note held through such participants will be governed by standing
instructions and customary practices and will be the responsibility of such
participants. The Issuer will not have any responsibility or liability for any
aspect of the records relating to, or payments made on account of, beneficial
ownership interests in a Global New Note for any New Note or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests or for any other aspect of the relationship between the Depository and
its participants or the relationship between such participants and the owners of
beneficial interests in the Global New Notes owning through such participants.
    
 
   
     Unless and until it is exchanged in whole or in part for certificated New
Notes in definitive form, the Global New Notes may not be transferred except as
a whole by the Depository to a nominee of such Depository or by a nominee of
such Depository to such Depository or another nominee of such Depository.
    
 
   
     Although the Depository has agreed to the foregoing procedures in order to
facilitate transfers of interests in each Global New Note among participants of
the Depository, it is under no obligation to perform or continue to perform such
procedures, and such procedures may be discontinued at any time. None of the
Trustee, the Issuer nor the Paying Agent will have any responsibility for the
performance by the Depository or its participants or indirect participants of
their respective obligations under the rules and procedures governing their
operations.
    
 
   
     Certificated Securities. Interests in each Global New Note will be
exchanged for Certificated Securities if (i) DTC notifies the Issuer that it is
unwilling or unable to continue as depositary for the Global New Note, or DTC
ceases to be a "Clearing Agency" registered under the Exchange Act, and a
successor depositary is not appointed by the Issuer within 90 days, or (ii) an
Event of Default has occurred and is continuing with respect to the related New
Notes. Upon the occurrence of any of the events described in the preceding
sentence, the Issuer will cause the appropriate Certificated Securities to be
delivered.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
   
     The following discussion is a summary of the material U.S. Federal income
tax considerations relevant to the exchange of Old Notes for New Notes pursuant
to the Exchange Offers and the ownership and disposition of the New Notes by
holders who acquire the New Notes pursuant to the Exchange Offers, but does not
purport to be a complete analysis of all potential tax effects. The discussion
is based upon the Internal Revenue Code of 1986, as amended (the "Code"), U.S.
Treasury Regulations (the "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
New 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 who hold the New Notes as part of a "straddle,"
"hedge" or "conversion transaction." In addition, this discussion is limited to
persons purchasing the Old Notes for cash at original issue. Moreover, the
effect of any applicable state, local or foreign tax laws is not discussed. The
discussion deals only with New 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 New 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 (unless, in the case of a
partnership, the IRS provides otherwise by Regulations), (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 (within the meaning of Section 7701(c)(30) of the Code) 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 New 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 matters discussed below. There can be no assurance that the IRS
will not take a different position concerning the tax consequences of the
exchange of Old Notes for New Notes and the ownership or disposition of the New
Notes by holders who acquire the New Notes pursuant to the Exchange Offers or
that any such position would not be sustained.
    
 
     PROSPECTIVE HOLDERS OF THE NEW 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.
 
   
EXCHANGE OFFERS
    
 
   
     The exchange of Old Notes for New Notes pursuant to the Exchange Offers
will not be treated as an exchange or other taxable event for U.S. Federal
income tax purposes because, under the Regulations, the New Notes do not differ
materially in kind or extent from the Old Notes. Rather, the New Notes received
by a holder will be treated as a continuation of the Old Notes in the hands of
such holder. As a result, there will be no U.S. Federal income tax consequences
to holders who exchange Old Notes for New Notes pursuant to the Exchange Offers
and any such holder will have the same tax basis and holding period in the New
Notes as it had in the Old Notes immediately before the exchange.
    
 
U.S. HOLDERS
 
     Interest. The stated interest on the New Notes generally will be taxable to
a U.S. holder as ordinary income at that time that it is paid or accrued, in
accordance with the U.S. holder's method of accounting for federal income tax
purposes. The New Notes are not expected to give rise to "original issue
discount" income in the hands of U.S. holders.
 
                                       130
<PAGE>   138
 
     Sale or Retirement of a Note. A U.S. holder of a New Note will recognize
gain or loss upon the sale, retirement, redemption or other taxable disposition
of such New 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 New Note. Subject to the market
discount rules discussed below, such gain or loss will be capital gain or loss.
The Taxpayer Relief Act of 1997 made certain changes to the Code with respect to
the taxation of capital gains of noncorporate taxpayers. In general, the maximum
tax rate for noncorporate taxpayers on long-term capital gains is 20% with
respect to capital assets (including the New Notes), but only if they have been
held for more than 18 months at the time of disposition. Gain realized by
noncorporate taxpayers on capital assets sold, having a holding period of more
than one year but not more than 18 months at the time of disposition, is taxed
as "mid-term" gain at a maximum 28% rate.
 
     U.S. holders should be aware that the resale of the New Notes may be
affected by the "market discount" rules of the Code under which a purchaser of a
New Note acquiring the New 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 New Note, to the extent of the market discount
that has accrued but not been included in income while the New Note was held by
such purchaser.
 
NON-U.S HOLDERS
 
  U.S. Withholding Tax. Interest paid to non-U.S. holders of the New 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 percent 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 for U.S. Federal income tax purposes
that is related to the Company through stock ownership or (b) a bank that
received the New 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 New 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 Regulations or an exemption is
otherwise established. If these requirements cannot be made, 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.
 
     In general, any gain realized by any non-U.S. holder upon the sale,
exchange or redemption of a New Note will not be subject to United States
withholding tax. However, such gain will be subject to U.S. withholding tax if a
non-U.S. holder is an individual who is present in the United States for a total
of 183 days or more during the taxable year in which the gain is realized and
certain other conditions are satisfied.
 
   
     U.S. Estate Tax. New Notes owned or treated as owned by an individual who
is not a citizen or resident (as specially defined for U.S. Federal estate tax
purposes) of the United States at the time of death ("Nonresident Decedent")
will not be includible in the Nonresident Decedent's gross estate for U.S.
Federal estate tax purposes as a result of the Nonresident Decedent's death,
provided that, at the time of death, the Nonresident Decedent does not own,
actually or constructively, 10% or more of the total combined voting power of
all classes of stock of the Company and payments with respect to such New Notes
would not have been effectively connected with the conduct of a trade or
business in the United States by the Nonresident Decedent. A Nonresident
Decedent's estate may be subject to U.S. Federal estate tax on property
includible in the estate for U.S. Federal estate tax purposes.
    
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     Certain noncorporate U.S. persons may be subject to information reporting
and backup withholding at a rate of 31% on payments of principal and interest on
the New Notes, and the proceeds from a disposition of the New 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 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. The Company will
also institute backup withholding if instructed to do so by the IRS. Holders of
the New Notes should consult their own tax advisors regarding their
qualification for exemption from backup
 
                                       131
<PAGE>   139
 
withholding and the procedure for obtaining such an exemption, if applicable.
However, interest paid with respect to a New 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, provided that the payor
does not have actual knowledge that the holder is a U.S. person.
 
     The payment of the proceeds from the disposition of New Notes to or through
the U.S. office of any broker, U.S. or foreign, will not be subject to
information reporting and possibly backup withholding if the owner certifies as
to its non-U.S. status under penalties of perjury or otherwise establishes an
exemption, provided that the broker does not have actual knowledge that the
holder is a U.S. person or that the conditions of any other exemption are not,
in fact, satisfied. The payment of the proceeds from the disposition of a New
Note to or through a non-U.S. office of a non-U.S. broker that is not a U.S.
related person will not be subject to information reporting or backup
withholding. For this purpose, a "U.S. related person" is (i) a controlled
foreign corporation for U.S. Federal income tax purposes or (ii) a foreign
person 50% or more of whose gross income from all sources for the three-year
period ending with the close of its taxable year preceding the payment (or for
such part of the period that the broker has been in existence) is derived from
activities that are effectively connected with the conduct of a U.S. trade or
business.
 
     In the case of the payment of proceeds from the disposition of New Notes to
or through a non-U.S. office of a broker that is a U.S. related person, the
Regulations require information reporting on the payment unless the broker has
documentary evidence in its files that the owner is a non-U.S. holder and the
broker has no knowledge to the contrary. Backup withholding will not apply to
payments made through foreign offices of a broker that is a U.S. person or a
U.S. related person (absent actual knowledge that the payee is a U.S. person).
 
     Any amounts withheld under the backup withholding rates from a payment to a
non-U.S. holder will be allowed as a credit against such non-U.S. holder's U.S.
Federal income tax liability, if any, or otherwise will be refunded, provided
that the requisite procedures are followed.
 
PROSPECTIVE FINAL REGULATIONS
 
     On October 6, 1997, new Regulations ("New Regulations") were issued that
modify the requirements imposed on a non-U.S. holder and certain intermediaries
for establishing the recipient's status as a non-U.S. holder eligible for
exemption from or reduction in U.S. withholding tax and backup withholding
described above. The New Regulations generally are effective for payments made
after December 31, 1998, subject to certain transition rules. (However, new
Temporary Regulations, effective for payments made after December 31, 1997,
require some non-U.S. holders to satisfy certain residency requirements when
claiming the benefits of an applicable income tax treaty.) In general, the New
Regulations do not significantly alter the substantive withholding and
information reporting requirements but rather unify current certification
procedures and forms and clarify reliance standards. In addition, the New
Regulations impose more stringent conditions on the ability of financial
intermediaries acting for non-U.S. holders to provide certifications on behalf
of non-U.S. holders, which may include entering into an agreement with the IRS
to audit certain documentation with respect to such certifications. Non-U.S.
holders should consult their own tax advisors to determine the effects of the
application of the New Regulations to their particular circumstances.
 
                              PLAN OF DISTRIBUTION
 
   
     Each broker-dealer that receives New Notes for its own account pursuant to
the Exchange Offers must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes. This Prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of New Notes received in exchange for Old Notes where
such Old Notes were acquired as a result of market-making activities or other
trading activities. The Company has agreed that, starting on the Expiration Date
with respect to each Exchange Offer and ending on 180 days after such Expiration
Date, it will make this Prospectus, as amended or supplemented, available to any
broker-dealer for use in connection with any such resale. In addition, until
such date, all dealers effecting transactions in the New Notes may be required
to deliver a prospectus.

<PAGE>   140
 
   
     The Company will not receive any proceeds from any sales of New Notes by
broker-dealers or others. New Notes received by broker-dealers for their own
account pursuant to the Exchange Offers 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 New Notes or a combination of such methods
of resale, at market prices prevailing at the time of resale, at prices related
to such prevailing market prices or negotiated prices. Any such resale may be
made directly to 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 New Notes. Any broker-dealer
that resells New Notes that were received by it for its own account pursuant to
the Exchange Offers and any broker or dealer that participates in a distribution
of such New Notes may be deemed to be an "underwriter" within the meaning of the
Securities Act and any profit from any such resale of New Notes and any
commissions received by any such persons may be deemed to be underwriting
compensation under the Securities Act. The Letter of Transmittal states that by
acknowledging that it will deliver and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.
    
 
   
     For a period of 180 days after the applicable Expiration Date, the Company
will promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal. The Company has agreed to pay all expenses
incident to the Exchange Offers (including the expenses of one counsel for the
holders of the respective Notes) other than commissions or concessions of any
brokers or dealers and will indemnify the holders of the Notes (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act.
    
 
                                 LEGAL MATTERS
 
     The validity of the New Notes will be passed upon for the Company by
Morrison & Foerster LLP, San Francisco, California.

                                   VERIO INC.
 
          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
 
   
     During the period from August 1, 1996 through the date of this Registration
Statement, Verio Inc. ("Verio" or the "Company") completed numerous business
combinations, whereby the Company acquired newly authorized redeemable,
convertible preferred stock, shares of common stock, or certain net assets of
entities operating in the Internet industry (ISPs), and completed the Buyout of
the remaining equity interests of certain ISPs in which it initially acquired a
less-than-100% equity position (collectively, the "Completed Acquisitions"). In
addition, the Company has entered into definitive agreements to acquire an
additional four ISPs, which acquisitions, in the opinion of management, are
probable to be completed, (the "Proposed Acquisitions"). The Company also has
contractual rights to effect additional Buyouts which have not been completed at
the date of this Registration Statement but two of which, in the opinion of
management, are probable to be completed and are also included as Proposed
Acquisitions. Business combinations, which are acquisitions of a 100% ownership
interest in the target business or of a majority ownership interest (upon
conversion of the preferred shares to common stock) on a fully diluted basis,
are accounted for using the purchase method of accounting. Acquisitions of
minority interests represented by preferred stock are accounted for using the
equity method of accounting, as described in Note 1 to the Consolidated
Financial Statements. The Completed Acquisitions and Proposed Acquisitions are
described in Note A to the accompanying pro forma condensed combined financial
statements.
    
 
   
     While the Company now seeks to acquire 100% of new ISPs, the Company's
early acquisition strategy was to rapidly build mass and scale by acquiring less
than 100% of its ISPs. In each case where the Company acquired less than 100% of
an ISP initially, it obtained the right to Buyout the remaining equity in the
future at a price based on either agreed upon revenue multiples or the fair
market value of the ISP. As part of its integration strategy, the Company is in
the process of effecting the Buyouts of its remaining non-wholly owned ISPs
through the use of cash on hand and the issuance of equity. As of the date of
this Registration Statement, Verio has consummated the Buyout of the following
twelve ISPs; On-Ramp Technologies, Inc.; NorthWestNet, Inc.; National Knowledge
Networks, Inc.; Access One, Inc.; Signet Partners, Inc.; Surf Network, Inc.;
Pacific Rim Network, Inc.; Internet Engineering Associates, Inc.; AimNet
Corporation; West Coast Online, Inc.; ServiceTech, Inc., and Clark Internet
Services, Inc. Verio currently expects to effect the Buyouts of the remaining
four ISPs in which it acquired a less-than-100% position during the remainder of
1998. With respect to those Buyouts that have not yet been completed, the
Company expects to consummate two of these Buyouts prior to or concurrent with
the proposed IPO, and considers these Buyouts probable. The Company has
contractual rights to effect the other two Buyouts and expects to complete these
Buyouts during the remainder of 1998. However, there can be no assurance that
the Company will be able to complete these Buyouts at the times, or in
accordance with the terms and conditions, that it currently contemplates. These
acquisitions will also be accounted for using the purchase method of accounting.
    
 
   
     The unaudited pro forma condensed combined balance sheet assumes that the
Completed Acquisitions and the Proposed Acquisitions occurred on December 31,
1997 and includes the December 31, 1997 historical consolidated balance sheets
of Verio and the acquired businesses adjusted for the pro forma effects of these
acquisitions. The unaudited pro forma condensed combined statement of operations
for the year ended December 31, 1997 assumes that the Completed Acquisitions and
the Proposed Acquisitions had occurred on January 1, 1997, and includes the
historical consolidated statements of operations of Verio and the Completed and
Proposed Acquisitions for the year ended December 31, 1997, adjusted for the pro
forma effects of the acquisitions. The unaudited pro forma condensed combined
balance sheet also assumes the conversion of the Preferred Stock into Common
Stock upon completion of the proposed IPO.
    
 
     The unaudited pro forma condensed combined statement of operations is not
necessarily indicative of the results of operations that would actually have
occurred if the transactions had been consummated as of January 1, 1997 and is
not intended to indicate the expected results for any future period. These
statements should be read in conjunction with the historical consolidated
financial statements and related notes thereto of Verio, and certain acquired
businesses, included herein. The actual purchase accounting adjustments may be
revised upon completion of the acquisitions.

     During the period from inception (March 1, 1996) to April 9, 1998, Verio
completed numerous business combinations, and completed the Buyout of the
remaining equity interests of certain ISPs in which it initially acquired a
less-than-100% equity position (Completed Acquisitions). In addition, the
Company has contractual rights to effect certain additional Buyouts which have
not been completed at the date of this Registration Statement but which, in the
opinion of management, are probable to be completed. These transactions are
collectively referred to as the "Proposed Acquisitions." All of the acquisitions
have been or will be accounted for using the purchase method of accounting.
Summary information regarding the Completed and Proposed Acquisitions is as

(D) PRO FORMA ADJUSTMENTS
 
     The following pro forma adjustments have been made to the condensed
combined balance sheet as of December 31, 1997 and the condensed combined
statement of operations for the year ended December 31, 1997. The purchase
accounting adjustments relating to the acquisitions completed prior to January
1, 1998 are included in the historical consolidated balance sheet of Verio as of
December 31, 1997.
 
   
          (1) To reflect cash and 1,704,000 shares of preferred stock, which is
     the approximate number of shares issued and proposed to be issued in
     connection with the Completed and Proposed Acquisitions subsequent to
     December 31, 1997, and the allocation of excess purchase price to goodwill
     in the amount of $69,025,000 and to adjust investments in affiliates for
     the proposed acquisitions of majority interests. Preferred shares issued
     for acquisitions were recorded at fair value as determined by the Company's
     Board of Directors and based on other third-party issuances of Company
     securities. In the opinion of management, the historical balances of all
     other assets acquired and liabilities assumed approximate fair value.
    
 
          (2) To eliminate equity accounts of the Proposed Acquisitions.
 
          (3) To eliminate intercompany revenue, expenses, receivables and
     payables.
 
   
          (4) To adjust amortization expense due to increase in carrying value
     of goodwill, using a ten-year life, including additional amortization
     expense related to consolidated acquisitions completed during 1997, as if
     such acquisitions had been completed as of January 1, 1997.
    
 
          (5) To eliminate minority interests share of equity and operations and
     equity in losses of affiliates upon acquisition of 100% ownership
     interests.
 
          (6) To eliminate income tax expense or benefit of acquired businesses
     due to consolidated net operating loss for the year ended December 31,
     1997.
 
   
          (7) To reflect the conversion of all preferred shares into common
     stock upon completion of the proposed IPO.
    
 
   
          (8) To reflect the conversion of 20,945,667 shares of preferred stock
     into common stock upon completion of the proposed IPO, including 1,704,000
     shares of preferred stock assumed to be issued and converted to common
     stock subsequent to December 31, 1997.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Verio Inc.:
 
     We have audited the accompanying consolidated balance sheets of Verio Inc.
and subsidiaries as of December 31, 1996 and 1997, and the related consolidated
statements of operations, stockholders' deficit, and cash flows for the period
from inception (March 1, 1996) to December 31, 1996 and the year ended December
31, 1997. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated 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.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Verio Inc.
and subsidiaries as of December 31, 1996 and 1997, and the results of their
operations and their cash flows for the period from inception (March 1, 1996) to
December 31, 1996 and the year ended December 31, 1997 in conformity with
generally accepted accounting principles.

in April 1996 and had no activity other than the sale of common stock to
founders prior to April 1, 1996.
 
     The accompanying consolidated financial statements include the accounts of
Verio and its majority owned subsidiaries, as described in Note 2. All
significant intercompany balances and transactions have been eliminated in
consolidation. The preparation of financial statements requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amount of revenue and expenses during
the reporting period. Actual results could differ from those estimates.
 
  (b) Cash and Cash Equivalents and Restricted Cash
 
     The Company considers all highly liquid debt instruments with original
maturities of three months or less to be cash equivalents. Included in cash
equivalents as of December 31, 1996 and December 31, 1997 are U.S. government,
municipal and corporate debt securities, money market accounts and commercial
paper, totaling $61,769,000 and $75,442,000 (exclusive of cash overdraft in the
amount of $11,228,000), respectively, with maturities ranging from thirty to
ninety days.
 
     Restricted cash and securities include U.S. government securities which are
classified as securities held to maturity and recorded at cost. At December 31,
1997, cost approximated market value.
 
  (c) Equipment and Leasehold Improvements
 
     Equipment and leasehold improvements are recorded at cost. Depreciation is
provided over the estimated useful lives of the assets ranging from 3 to 5 years
using the straight-line method. Leasehold improvements are amortized over the
shorter of the lease term or the estimated useful life of the asset.
 
  (d) Investments in Affiliates and Consolidation of Subsidiaries
 
     Investments in affiliates represent newly issued preferred shares of
various affiliates. The preferred shares are convertible at the option of the
Company into common shares on a one-for-one basis and represent future common
stock ownership interests, upon conversion, of less than 50%. As the Company did
not acquire a common stock ownership interest, these investments are recorded at
cost until such time as the preferred shares are converted to common. In
addition, if these entities incur losses resulting in the equity of the common
shareholders being reduced to zero, the Company will utilize the equity method
of accounting for these investments and will generally recognize 100% of all
losses of the affiliates from that date, up to the amount of the Company's
investment, based on the inability of the majority common shareholders to fund
additional losses. During the year ended December 31, 1997, the Company
recognized equity in losses of affiliates of $1,958,000 under this method of
accounting.
 
   
     The Company has also acquired preferred shares in certain entities which
are convertible into future common stock ownership interests of greater than
50%. In these situations, the Company has majority representation on the Board
of Directors and majority voting rights, exercises significant control over the

entities' operations, and intends to acquire a 100% common ownership interest in
the future. Accordingly, the accounts of these investees have been consolidated
with those of the Company in the accompanying consolidated financial statements
from the dates of acquisition (see note 2).
 
  (e) Other Assets
 
     The excess of cost over the fair value of net assets acquired, or goodwill,
is amortized using the straight-line method over a 10-year period. Other
intangibles are amortized using the straight-line method over periods ranging
from three to seven years.
 
  (f) Long-Lived Assets
 
     The Company evaluates the carrying value of its long-lived assets under the
provisions of Statement of Financial Accounting Standards No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lives Assets to be Disposed
Of (SFAS 121). SFAS 121 requires impairment losses to be recorded on long-lived
assets used in operations, including goodwill, when indications of impairment
are present and the undiscounted future cash flows estimated to be generated by
those assets are less than the assets' carrying amount. In addition, the
recoverability of goodwill is further evaluated under the provisions of APB
Opinion No. 17, Intangible Assets, based upon undiscounted cash flows. If such
assets are impaired, the impairment to be recognized is measured by the amount
by which the carrying amount of the assets exceeds the estimated fair value of
the assets. Assets to be disposed of are reported at the lower of the carrying
value or fair value, less costs to sell.
 
  (g) Revenue Recognition
 
     Revenue related to Internet services is recognized as the services are
provided, and deferred and amortized to operations for amounts billed relating
to future periods. Installation and customer set-up fees are recognized upon
completion of the services. Revenue from consulting services is recognized as
the services are provided. Revenue from hardware and software sales is
recognized upon shipment of the respective products.
 
  (h) Income Taxes
 
     The Company accounts for income taxes under the provisions of Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS 109).
SFAS 109 requires recognition of deferred tax liabilities and assets for the
expected future tax consequences of events that have been included in the
financial statements or tax returns. Under this method, deferred tax liabilities
and assets are determined based on the difference between the financial
statement and tax bases of assets and liabilities using enacted tax rates in
effect for the year in which the difference is expected to reverse.
 
  (i) Stock-Based Compensation
 
     The Company accounts for its stock-based employee compensation plans using
the intrinsic value based method prescribed by Accounting Principles Board
Opinion No. 25, Accounting for Stock Issued to Employees, and related
interpretations (APB 25). The Company has provided pro forma disclosures of net
loss and loss per share as if the fair value based method of accounting for the
plans, as prescribed by Statement of Financial Accounting Standards No. 123,
Accounting for Stock-Based Compensation (SFAS 123), had been applied. Pro forma
disclosures include the effects of employee stock options granted during the
period and year ended December 31, 1996 and 1997.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  (j) Loss Per Share
 
     Loss per share is presented in accordance with the provisions of Statement
of Financial Accounting Standards No. 128, Earnings Per Share, (SFAS 128). SFAS
128 replaced the presentation of primary and fully diluted earnings (loss) per
share (EPS), with a presentation of basic EPS and diluted EPS. Under SFAS 128,
basic EPS excludes dilution for common stock equivalents and is computed by
dividing income or loss available to common shareholders by the weighted average
number of common shares outstanding for the period. Diluted EPS reflects the
potential dilution that could occur if securities or other contracts to issue
common stock were exercised or converted into common stock and resulted in the
issuance of common stock. Basic and diluted EPS are the same in 1996 and 1997,
and all common stock equivalents are antidilutive.
 
(2) BUSINESS COMBINATIONS AND INVESTMENTS IN AFFILIATES
 
     During the period from inception (March 1, 1996) to December 31, 1996, the
Company completed seven business combinations and investments for cash and notes
payable. All of the acquisitions were accounted for using the purchase method of
accounting or at cost. For those businesses acquired and consolidated, the
results of operations for the acquired businesses are included in the Company's
consolidated statement of operations from the dates of acquisition. Summary
information regarding the business combinations is as follows:

     The pro forma results do not necessarily represent results that would have
occurred if the consolidated acquisitions had taken place as of January 1, 1996,
nor are they necessarily indicative of the results of future operations.
 
     For all of its less-than-100%-owned ISP affiliates, the Company has the
option to acquire all of the remaining ownership interests. Generally, the
option may be exercised beginning one year from the date of the initial
investment or upon the earlier of the completion of an initial public offering
of common stock by the Company or a significant strategic investment in the
Company. In one case, the Company's option becomes mandatorily exercisable upon
completion of an initial public offering.
 
   
     Subsequent to December 31, 1997 and through February 25, 1998, the Company
has completed or expects to complete the acquisition of the remaining ownership
interests and acquisitions of 12 ISPs, for total consideration of approximately
$50 million in preferred stock and cash.

(a)  In June 1997, the Company completed a debt offering of $150,000,000, 13.5%
     Senior Notes due 2004 (the "1997 Notes") and warrants to purchase 2,112,480
     shares of common stock at $.01 per share, which were valued at
     approximately $12,675,000 based on the Company's most recent equity
     offering. Interest on the 1997 Notes is payable semi-annually on June 15
     and December 15 of each year. The value attributed to the warrants has been
     recorded as debt discount and is being amortized to interest expense using
     the interest method over the term of the 1997 Notes. Upon closing, the
     Company deposited U.S. Treasury securities in an escrow account in an
     amount that, together with interest on the securities, will be sufficient
     to fund the first five interest payments (through December 1999) on the
     1997 Notes. This restricted cash and securities balance totaled $38,195,404
     at December 31, 1997. The 1997 Notes are redeemable on or after June 15,
     2002 at 103% of the face value.
    
 
     The indenture covering the 1997 Notes includes various covenants
restricting the payment of dividends, additional indebtedness, disposition of
assets, and transactions with affiliates.
 
     Maturities of lines of credit, notes payable and long-term debt are as

respectively.
    
 
   
     In addition, the Company has entered into agreements with two
telecommunications companies to provide the Company with products and services
to be used in its operations. Under one agreement, the minimum payments as of

     Under the second agreement, the Company is obligated to spend a total of
$39 million between June 16, 1997 and June 16, 2002 of which $1,500,000 had been
paid as of December 31, 1997. Annual payments will be based on actual usage by
the Company.
 
     The Company had an outstanding irrevocable letter of credit in the amount
of $1.1 million as of December 31, 1997. This letter of credit, which is
automatically renewed after one year at the discretion of the bank, not to be
extended beyond January 31, 2003, is to collateralize the Company's lease
obligation to a third party. The fair value of this letter of credit
approximates contract value which is fixed over the life of the commitment.
Restricted cash in the amount of $1,400,000 secures the letter of credit.
 
(5) PREFERRED STOCK
 
     Series A, B and C preferred shares were issued in 1996 and 1997 at $3, $6
and $8 per share, respectively, for total proceeds of $18,100,001, $60,170,004
and $20,000,000, respectively, and are convertible into common

stock initially on a one-for-one basis. In December 1997, the Company also
issued 680,000 shares of Series D-1 preferred shares at $15 per share in
connection with an acquisition. The preferred shares are entitled to receive
dividends equal, on an as-converted basis, to any amount paid to common
stockholders. In the event of any liquidation or dissolution of the Company,
including certain mergers, consolidations and asset sales, holders of the
preferred shares are entitled to receive an amount equal to the original
issuance price, plus any declared and unpaid dividends.
    
 
     In addition, the Series A, B and C preferred shares are subject to
mandatory redemption, in total, by the Company in October 2004. The Series D-1
preferred shares are not redeemable. Upon redemption, the Series C shares are
senior to Series B shares, which are senior to Series A shares, on the basis
provided in the preferred stock terms. Series A, B, C and D-1 preferred shares
may be converted into shares of common stock at any time at the option of the
holder. The Series A, B, C and D-1 preferred shares are also subject to
mandatory conversion upon consummation of a public offering of common stock
resulting in proceeds to the Company of not less than $30 million and at an
offering price per share equal to at least $15. In addition, shares of Series
D-1 preferred stock are subject to mandatory conversion upon the election of
each of the Series A, B and C classes, each voting as a separate class, to
convert to common.
 
   
(6) STOCK-BASED COMPENSATION PLANS
    
 
   
     The Company has established Incentive Stock Option Plans (the Plans)
whereby, at the discretion of the Board of Directors (the Board), the Company
may grant stock options to employees of the Company and its controlled
subsidiaries. As of December 31, 1997, the Company had reserved 2,750,000 shares
for issuance under the Plans. The Plans were amended in February 1998 to
increase the number of shares reserved for issuance to 3,750,000. The option
price is determined by the Board at the time the option is granted, but in no
event is less than the fair market value of the Company's common stock at the
date of grant, as determined by the Board. As of December 31, 1996 and December
31, 1997, options had been granted entitling the holders to purchase 707,200 and
2,237,050 shares of the Company's common stock, respectively, at exercise prices
of $1, $3, $6, $6.75 and $8.50 per share. Options granted on or before December
19, 1997, vest over a five year period, and expire ten years from the date of
grant. Options granted December 20, 1997, or later, vest over a four year
period, and expire eight years from the date of grant. In certain circumstances,
options vest earlier or later based upon the fair value of the Company's common
shares or upon reaching certain performance targets, as defined, and in the case
that such performance targets are not met, such performance-based options vest
seven years from the date of grant. Performance based options granted on or
before December 19, 1997, expire ten years from the date of grant, and
performance based options granted December 20, 1997, or later, expire eight
years from the date of grant. As of December 31, 1997, 54,700 options, in total,
were vested and exercisable. Options may be exercised prior to their scheduled
vesting date, but are subject to a repurchase by the Company at the exercise
price until the scheduled vesting date. The weighted average contractual term of
outstanding options was approximately 5 years at December 31, 1997.

</TABLE>
 
   
     As discussed in Note 1, the Company applies APB Opinion 25 and related
interpretations in accounting for its stock compensation plan. Accordingly,
since the Company grants stock options with exercise prices equal to fair value
at the date of grant, no compensation expense has been recognized relating to
option grants in 1996 and 1997. During the period and year ended December 31,
1996 and 1997, the per share weighted-average fair value of stock options
granted was $.46 and $1.08, respectively, on the date of grant using the
Black-Scholes option-pricing model with the following weighted-average
assumptions: no dividends or volatility, risk-free interest rate of 6%, and
expected life of three years. If the Company had recorded compensation expense
for the period and year ended December 31, 1996 and 1997, based on the fair
value of the options at the grant date under SFAS No. 123, net loss available to
common stockholders would increase to $5,210,000 and $46,737,000, respectively,
and basic and diluted net loss per common share would increase to $4.78 and
$40.83, respectively.
    
 
(7) INCOME TAXES
 
   
     At December 31, 1997, the Company has a net operating loss carryforward for
federal income tax purposes of approximately $49.9 million, of which $5.9
million and $44.0 million is available to offset future federal taxable income,
if any, through 2011 and 2012, respectively. As a result of various preferred
stock transactions during 1996 and 1997, management believes the Company has
undergone an "ownership change" as defined by section 382 of the Internal
Revenue Code. Accordingly, the utilization of a portion of the net operating
loss carryforward may be limited. Due to this limitation, and the uncertainty
regarding the ultimate utilization of the net operating loss carryforward, no
tax benefit for losses has been recorded by the Company in 1996 and 1997, and a
valuation allowance has been recorded for the entire amount of the deferred tax
asset relating to the net operating loss carryforward of $18.6 million. Net
other temporary differences relating to differences in the carrying amounts of
assets and liabilities for financial statement and income tax purposes are not
significant.
    
 
(8) CONCENTRATION OF CREDIT RISK AND FAIR VALUE OF FINANCIAL INSTRUMENTS
 
   
     Financial instruments that potentially subject the Company to
concentrations of credit risk consist primarily of cash, cash equivalents and
accounts receivable. As of December 31, 1996 and 1997, the Company had no
concentrations of credit risk. Concentrations of credit risk with respect to
trade receivables are limited

due to the large number of customers comprising the Company's customer base and
the relatively minor balances of each individual account. At December 31, 1996
and December 31, 1997, the fair value, of the Company's financial instruments
approximate their carrying value, based on their terms and interest rates.
 
   
(9) EMPLOYEE BENEFIT PLAN
    
 
   
     The Company has a 401(k) Plan (the Plan) for all full time employees of the
Company. The Company may make discretionary contributions to the Plan on behalf
of employees that meet certain contribution eligibility requirements defined
under the terms of the Plan. The Company did not make any contributions to the
Plan during 1996 or 1997.

                         NOTES TO FINANCIAL STATEMENTS
                                 JULY 31, 1996
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Business and Basis of Presentation
 
   
     On-Ramp Technologies, Inc. (the Company) was incorporated in the State of
Texas on December 27, 1993. The Company's business consists of providing
regional internet access services, and hardware and software sales and
consulting, to customers in Texas and Georgia.
    
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
 
  Revenue Recognition
 
     Internet services are recognized as the services are provided. The Company
records deferred revenue for amounts billed and/or collected in advance.
 
     Revenue from consulting services is recognized as the services are
provided. Revenue from hardware and software sales is recognized upon shipment
of the respective products.
 
  Equipment
 
     Equipment is stated at cost, less accumulated depreciation. Depreciation is
recorded using the straight-line method over the estimated useful life of the
related assets of three years. Costs for normal repairs and maintenance are
expensed as incurred.
 
  Income Taxes
 
     Income taxes are accounted for under the provisions of Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes, (SFAS 109).
Under SFAS 109, deferred income taxes are recognized for the future tax
consequences of differences between the tax bases of assets and liabilities and
their financial reporting amounts at each year-end based on enacted tax laws and
statutory rates applicable to the periods in which the differences are expected
to affect taxable income. Valuation allowances are established, when necessary,
to reduce deferred tax assets to the amount expected to be realized.
 
  Long-Lived Assets
 
   
     In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121, Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of (SFAS 121). This
statement was effective for financial statements for fiscal years beginning
after December 15, 1995. Statement No. 121 requires impairment losses to be
recorded on long-lived assets used in operations when indicators of impairment
are present and the undiscounted future cash flows estimated to be generated by
those assets are less than the assets' carrying amount. If such assets are
considered to be impaired, the impairment to be recognized is measured by the
amount by which the carrying amount of the assets exceeds the fair value of the
assets. Assets to be disposed of are reported at the lower of the carrying
amount or fair value less costs to sell. The adoption of SFAS 121 as of November
1, 1995 did not have a significant effect on the Company's financial position or
results of operations.
    
 
  Stock Based Compensation
 
     In October 1996, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, Accounting for Stock-Based
Compensation, (SFAS No. 123), which establishes a fair
 
                                      F-34

                           ON-RAMP TECHNOLOGIES, INC.
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
value-based method of accounting for stock-based compensation plans. Companies
are encouraged to adopt all provisions of SFAS No. 123 and are required to
comply with the disclosure requirements of SFAS No. 123, which was effective for
fiscal years beginning after December 15, 1995. The Company will continue to
account for stock based compensation under the provisions of APB Opinion No. 25
and will provide the pro forma disclosures required by SFAS 123.

     Rent expense for the nine months ended July 31, 1996 totaled $90,999.
 
  Concentration of Credit Risk and Financial Instruments
 
     The Company provides unsecured credit to customers in the normal course of
business. Failure of the customers to pay could result in losses up to the
recorded receivable balances. The Company does not have any customers that
represent greater than 5% of total revenue at July 31, 1996.
 
     The Company conducts business in Texas and Georgia. Customers who operate
in Texas represent approximately 97% of the Company's customer base and accounts
receivable.
 
   
     At July 31, 1996, the fair values of the Company's financial instruments
approximate their carrying values based on their terms and interest rates.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
(5) STOCKHOLDERS' EQUITY
 
     Effective August 1, 1996, the Company issued 1,250,000 shares of newly
authorized redeemable, convertible preferred stock to Verio Inc. (Verio)for cash
consideration of $2,336,816, cancellation of indebtedness in the amount of
$1,663,184, and a note receivable of $4,175,000. The preferred shares are
convertible into common shares on a one for one basis and represent a 50.82%
interest in the Company upon conversion. The preferred shares are redeemable at
the option of the holder at any time, vote on an as-converted basis, and have a
liquidation preference equal to the issuance price. On October 4, 1996, Verio
purchased 100,000 shares of common stock from two Company shareholders for cash
consideration of $600,000, representing an additional 4.07% interest in the
Company. In addition, Verio acquired an option to acquire a 100% common stock
ownership in the Company in the future upon the occurrence of certain events,
including an initial public offering of Verio common stock.
 
     The Company established a stock option plan (the Plan) which provides that
salaried officers or key employees, non-employee directors, and consultants who
provide services to the Company may, at the discretion of the Board of
Directors, be granted options to purchase shares of common stock. 130,560 shares
of the Company's Common Stock have been authorized for issuance under the Plan,
of which 59,878 shares were granted during the nine months ended July 31, 1996,
with an exercise price of $6.34 per share. There were no options exercised or
canceled during the nine months ended July 31, 1996. As of July 31, 1996, 11,976
options were exercisable.
 
     Generally, options vest 20% or 25% on the date of grant of the option and
the balance vests thereafter over a 4 or 3 year period.
 
     During the nine months ended July 31, 1996, the per share weighted-average
fair values of stock options granted was $.71 on the date of grant using the
Black-Scholes option-pricing model with the following weighted-average
assumptions; expected dividend yield 0%, risk-free interest rate of 6%, and
expected life of four years. If the Company determined compensation expense for
the nine months ended July 31, 1996 based on the fair value of the options at
the grant date under SFAS No. 123, net loss would have been approximately
$468,000.
 
(6) INCOME TAXES
 
     At December 31, 1995, the Company has a net operating loss carryforward for
federal income tax purposes of $534,000 which is available to offset future
federal taxable income, if any, through 2010. Management believes the Company
has undergone an ownership change under section 382 of the Internal Revenue Code
and, accordingly, the utilization of the net operating loss carryforward
incurred prior to this ownership change is limited. Due to this limitation and
the uncertainty regarding the ultimate utilization of the net operating loss
carryforward a valuation allowance has been recorded for the full amount of the
deferred tax asset related to the net operating loss carryforward, which
represents the only significant temporary difference as of December 31, 1996.

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION
 
  Business and Basis of Presentation
 
     Global Enterprise Services, Inc. (GES) was formed in August 1992 to provide
internet services to subscribers on a national and international basis through a
high performance telecommunications network. The accompanying financial
statements include the accounts of the domestic operations (Network Division),
assuming that the Network Division had been operated separately as of January 1,
1994 and thereafter.
 
     In preparing the accompanying financial statements, management has
allocated certain assets, liabilities, revenue and expenses based upon the
characteristics of the accounts and the business divisions to which they relate.
Expenses which are not directly related to a particular division are allocated
based upon revenue or payroll expense of the division which, in the opinion of
management, represents a reasonable and appropriate method of allocation.
 
     Effective January 17, 1997, the net assets of the Network Division were
acquired by Verio Inc.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
 
  Revenue Recognition
 
     Internet services are recognized as the services are provided. The Network
Division records deferred revenue for amounts billed and/or collected in
advance.
 
  Equipment
 
     Equipment, including any assets under capital leases, is stated at cost,
less accumulated depreciation and amortization. Depreciation and amortization is
recorded using the straight-line method over the estimated useful lives of the
related assets or the lease term, which range from five to seven years. Costs
for normal repairs and maintenance are expensed as incurred.
 
  Income Taxes
 
     The operations of the Network Division are included in the income tax
returns of GES, which was treated as a subchapter S Corporation in 1994 and
through August 14, 1995, and a C Corporation beginning on August 15, 1995.
 
     Income taxes are accounted for under the provisions of Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes, (SFAS 109).
Under SFAS 109, deferred income taxes are recognized for the future tax
consequences of differences between the tax bases of assets and liabilities and
their financial reporting amounts at each year-end based on enacted tax laws and
statutory rates applicable to the periods in which the differences are expected
to affect taxable income. Valuation allowances are established, when necessary,
to reduce deferred tax assets to the amount expected to be realized.
 
     No tax benefit has been allocated to the Network Division in 1994, 1995 and
1996 or for the period ended January 17, 1997, due to losses at the GES level
for which no tax benefit has been provided for financial statement purposes.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Concentration of Credit Risk and Financial Instruments
 
     The Network Division provides unsecured credit to customers in the normal
course of business. Failure of the customers to pay could result in losses up to
the recorded receivable balances. The Network Division does not have any
customers that represent greater than 5% of total revenue for the years ended
December 31, 1994, 1995 and 1996 or for the period ended January 17, 1997.
 
   
     At December 31, 1996, the fair values of the Network Division's financial
instruments approximate their carrying values based on their terms and interest
rates.
    
 
  Long-Lived Assets
 
   
     In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121, Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of (SFAS 121). This
statement was effective for financial statements for fiscal years beginning
after December 15, 1995. Statement No. 121 requires impairment losses to be
recorded on long-lived assets used in operations when indicators of impairment
are present and the undiscounted future cash flows estimated to be generated by
those assets are less than the assets' carrying amount. If such assets are
considered to be impaired, the impairment to be recognized is measured by the
amount by which the carrying amount of the assets exceeds the fair value of the
assets. Assets to be disposed of are reported at the lower of the carrying
amount or fair value less costs to sell. The adoption of SFAS 121 effective
January 1, 1996 did not have a significant effect on the Network Division's
financial position or results of operations.

participant's contribution up to a maximum of 10% of gross salary, as defined.
Employee contributions are immediately vested. Contributions to the savings plan
on behalf of the Network Division employees for the years ended December 31,
1994, 1995 and 1996 were $3,253, $1,697 and $6,838, respectively.

(5) NATIONAL SCIENCE FOUNDATION GRANTS
 
     The Network Division receives grant revenue from the National Science
Foundation (NSF) to provide network connections to certain not-for-profit
educational institutions. Funding is received on a per entity basis. The grant
revenue is recognized ratably over the term of the contract with the
not-for-profit educational institution, which is generally twelve months. Grant
revenue amounted to $131,166, $99,487 and $47,112, in 1994, 1995 and 1996,
respectively. Total amounts receivable at December 31, 1994, 1995 and 1996 were
$34,990, $72,199 and $23,243, respectively.
 
     In September 1994, GES and the Network Division entered into a four year
cooperative agreement with the NSF to provide for interregional connectivity for
the Network Division's United States research and educational customers in the
aggregate amount of $625,115. Pursuant to the agreement, the Network Division
will be reimbursed by the NSF for costs associated with upgrading the Network
Division's existing telecommunications network. The level of funding for each
year will be determined based upon a progress review of the Network Division by
the NSF and the availability of NSF funds. The Network Division is required to
submit an annual plan to the NSF. For the years ended December 31, 1995 and
1996, respectively, the Network Division recognized $154,344 and $196,169 as a
reduction to internet services operating costs. No amounts were recognized for
the year ended December 31, 1994. Total amounts receivable were $30,904 and
$10,326 as of December 31, 1995 and 1996, respectively.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Verio Inc.:
 
     We have audited the accompanying balance sheets of Compute Intensive, Inc.
as of December 31, 1995 and 1996, and the related statements of operations,
stockholders' equity (deficit), and cash flows for each of the years in the two
year period ended December 31, 1996 and for the period ended February 18, 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.
 
   
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Compute Intensive, Inc. as
of December 31, 1995 and 1996, and the results of its operations and its cash
flows for each of the years in the two year period ended December 31, 1996 and
for the period ended February 18, 1997 in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1995 AND 1996
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization and Basis of Presentation
 
     Compute Intensive, Inc. (the Company) was incorporated in the State of
California on December 31, 1993. The Company has three distinct areas of
business; providing regional internet access services to customers in California
and New Mexico, software and hardware consulting and sales, and software
development and implementation.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
 
  Revenue Recognition
 
     Internet services are recognized as the services are provided. The Company
records deferred revenue for amounts billed and/or collected in advance.
 
     Revenue from consulting services is recognized when services have been
rendered. On fixed price contracts, revenue is recognized over the course of the
contract using the percentage-of-completion method. The Company provides for any
anticipated losses on such contracts in the period in which such losses are
first determinable.
 
   
     Revenue from hardware and software sales is recognized upon shipment of the
respective products if the Company has no significant future obligations and
collectibility is probable.
    
 
  Equipment
 
     Equipment, including any assets under capital leases, is stated at cost,
less accumulated depreciation and amortization. Depreciation and amortization is
recorded using the straight-line method over the estimated useful lives of the
related assets on the lease term, which range from five to seven years. Costs
for normal repairs and maintenance are expensed as incurred.
 
  Income Taxes
 
     Income taxes are accounted for under the provisions of Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes, (SFAS 109).
Under SFAS 109, deferred income taxes are recognized for the future tax
consequences of differences between the tax bases of assets and liabilities and
their financial reporting amounts at each year-end based on enacted tax laws and
statutory rates applicable to the periods in which the differences are expected
to affect taxable income. Valuation allowances are established, when necessary,
to reduce deferred tax assets to the amount expected to be realized.
 
  Fair Value of Financial Instruments
 
   
     Statement of Financial Accounting Standards No. 107 requires disclosure
about fair value for all financial instruments whether or not recognized for
financial statement purposes. Management estimates that the fair values of all
financial instruments as of December 31, 1995 and 1996 approximate their
carrying values based on their terms and interest rates. The use of different
market assumptions and/or estimation methodologies may have a significant effect
on the estimated fair values.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Long-Lived Assets
 
   
     In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121, Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of (SFAS 121). This
statement was effective for financial statements for fiscal years beginning
after December 15, 1995. Statement No. 121 requires impairment losses to be
recorded on long-lived assets used in operations when indicators of impairment
are present and the undiscounted future cash flows estimated to be generated by
those assets are less than the assets' carrying amount. If such assets are
considered to be impaired, the impairment to be recognized is measured by the
amount by which the carrying amount of the assets exceeds the fair value of the
assets. Assets to be disposed of are reported at lower of the carrying amount or
fair value less costs to sell. The adoption of SFAS 121 in 1996 did not have a
significant effect on the Company's financial position or results of operations.
    
 
  Stock Based Compensation
 
     In October 1996, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, Accounting for Stock-Based
Compensation, (SFAS No. 123), which establishes a fair value-based method of
accounting for stock-based compensation plans. Companies are encouraged to adopt
all provisions of SFAS No. 123 and are required to comply with the disclosure
requirements of SFAS No. 123, which was effective for fiscal years beginning
after December 15, 1995. The Company will continue to account for stock based
compensation under the provisions of APB Opinion No. 25 and will provide the pro
forma disclosures required by SFAS 123.
 
  Reclassifications
 
     Certain reclassifications have been made to the 1995 financial statements
to conform with the 1996 presentation.

     Rent expense for the years ended December 31, 1995 and 1996 and the period
ended February 18, 1997 was $83,148, $128,130 and $27,800, respectively.
 
  Concentration of Credit Risk
 
     The Company provides unsecured credit to customers in the normal course of
business. Failure of the customers to pay could result in losses up to the
recorded receivable balances. The Company's largest customer represented
approximately 32% and 20% of total revenues for the years ended December 31,
1995 and 1996, respectively.
 
     The Company conducts business in California and New Mexico. Customers who
operate in California represent at least 75% of the Company's customer base and
accounts receivable.
 
(5) EMPLOYEE BENEFIT PLAN
 
     The Company has a Simplified Employee Pension Plan (the Plan) covering all
employees who meet certain eligibility requirements. The Company may make
discretionary contributions to the Plan on behalf of

employees that meet certain contribution eligibility requirements defined under
the terms of the Plan. The Company did not make any contributions to the Plan
during 1995 or 1996.
 
(6) STOCKHOLDERS' EQUITY AND REDEEMABLE PREFERRED STOCK
 
     On February 18, 1997, the Company issued 770,234 shares of newly authorized
redeemable, convertible preferred stock to Verio for cash consideration of
$4,899,998. The preferred shares are convertible into common shares on a 1.000
for 1.0017 basis and represent a 55% ownership interest in the Company upon
conversion. The preferred shares are redeemable at the option of the holder at
any time, vote on an as-converted basis, and include a liquidation preference
equal to the issuance price. In addition, Verio acquired an option to acquire a
100% common stock ownership in the Company which it may exercise at any time on
or after one year following the issuance date of the preferred shares. Upon the
initial public offering of Verio common stock or a significant strategic
investor in Verio, Verio is required to exercise the option.
 
   
     The Company's 1995 Stock Option/Stock Issuance Plan (the Plan) was adopted
by the Board of Directors and approved by the shareholders of the Company in
March 1995. The Plan provides that salaried officers or key employees,
non-employee directors, and consultants who provide services to the Company may,
at the discretion of the plan administrator, be granted options to purchase
shares of common stock. 250,000 shares of the Company's Common Stock have been
authorized for issuance under the Plan, of which 131,000 and 29,500 nonqualified
options were granted in 1995 and 1996, respectively, with an exercise price of
$.05 and $.001 per share, respectively. All options were granted at fair value
at the date of grant, as determined by the Company's Board of Directors. There
were no options exercised and 18,176 were canceled during 1996.
    
 
     Generally, options vest 25% on the first anniversary of the option grant
date and the balance vests thereafter in equal successive monthly installments
over the next 36 months of service. Option grants to nonemployee directors must
be approved by the Board.
 
     During 1995 and 1996, the per share weighted-average fair values of stock
options granted was $.01 and $.65, respectively, on the date of grant using the
Black-Scholes option-pricing model with the following weighted-average
assumptions for both years; expected dividend yield 0%, risk-free interest rate
of 6%, and expected life of three years. If the Company determined compensation
expense in 1995 and 1996 based on the fair value of the options at the grant
date under SFAS No. 123, net loss and net earnings would not have been
significantly different than the historical results of operations.

businesses and organizations in the Northwest since 1991.
 
     On January 1, 1996, NWACC completed a transaction that included the
creation of NorthWestNet. The transaction consisted of the transfer of
substantially all of NWACC's operating assets and liabilities to NorthWestNet in
exchange for 4,000,000 shares of common stock, which represented all of the
outstanding common stock of NorthWestNet. This transaction represented a
tax-free transfer pursuant to the Internal Revenue Code (IRC) section 351. In
connection with the transaction, all NWACC employees became NorthWestNet
employees.
 
     NWACC's relationship to NorthWestNet, is now that of a stockholder,
currently the majority stockholder. NWACC intends to maintain its tax-exempt
status under IRC section 501(c)(3); however, its activities are independent of
NorthWestNet and its employees.
 
  (c) Basis of Presentation
 
     There was no change in the carrying amounts of assets and liabilities
transferred from NWACC to NorthWestNet effective January 1, 1996. The
accompanying financial statements include the accounts of NWACC through December
31, 1995, presented as Predecessor Company.
 
     The carrying amounts of net assets transferred from NWACC to NorthWestNet
effective January 1, 1996 are summarized as follows:

     All short-term investments with original maturities of three months or less
at date of purchase are considered to be cash equivalents.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  (e) Concentrations of Credit Risk
 
     Financial instruments that potentially subject NorthWestNet to
concentrations of credit risk consist principally of cash equivalents and
accounts receivable. NorthWestNet's cash equivalents represent investments in
money market funds which are readily convertible to cash. Accounts receivable
are principally from NorthWestNet's customers located throughout the Northwest.
 
  (f) Long-Lived Assets
 
   
     In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121, Accounting for the Impairment of
Long-Lived Assets and Long-Lived Assets to Be Disposed Of (SFAS 121). This
statement was effective for financial statements for fiscal years beginning
after December 15, 1995. Statement No. 121 requires impairment losses to be
recorded on long-lived assets used in operations when indicators of impairment
are present and the undiscounted future cash flows estimated to be generated by
those assets are less than the assets' carrying amount. If such assets are
considered to be impaired, the impairment to be recognized is measured by the
amount by which the carrying amount of the assets exceeds the fair value of the
assets. Assets to be disposed of are reported at the lower of the carrying
amount or fair value less costs to sell. The adoption of SFAS 121 effective July
1, 1996 did not have a significant effect on the NorthWestNet's financial
position or results of operations.
    
 
  (g) Revenue Recognition
 
     Revenues consist primarily of Internet access fees, connection fees and
on-line information service fees. Internet access fees consist of fixed monthly
amounts and are recognized ratably over the terms of the service contracts.
Connection fees, representing customer site equipment and installation charges,
are recognized upon installation of a customer's Internet connectivity. Fixed
on-line information service fees are recognized ratably over the terms of the
service contracts. Volume-based on-line information service fees are recognized
as such services are delivered. Payments received in advance of providing
services are deferred until the period such services are provided.
 
  (h) Advertising Costs
 
     Advertising costs are expensed as incurred.
 
  (i) Depreciation and Amortization
 
     Equipment, furniture and leasehold improvements are stated at cost.
Depreciation and amortization are provided on the straight-line method over the
estimated useful lives of the assets, or the lease term, if shorter. The
estimated useful lives of the assets are as follows:

  (j) Use of Estimates
 
     NorthWestNet management has made a number of estimates and assumptions
relating to the reporting of assets and liabilities, revenues and expenses, and
disclosure of contingent assets and liabilities to prepare these financial
statements in conformity with generally accepted accounting principles. Actual
results could differ from those estimates.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  (k) Income Taxes
 
     NorthWestNet accounts for income taxes using the asset and liability
method. Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to temporary differences between the financial
statement carrying amounts and tax bases of existing assets and liabilities.
 
     NWACC was exempt from the payment of Federal income taxes under IRC section
501(c)(3). Therefore, no provision for income taxes was required through
December 31, 1995.
 
  (l) Stock-Based Compensation
 
     Prior to July 1, 1996, NorthWestNet accounted for its stock option plan in
accordance with the provisions of Accounting Principles Board (APB) Opinion No.
25, Accounting for Stock Issued to Employees, and related interpretations. As
such, compensation expense would be recorded on the date of grant only if the
current market price of the underlying stock exceeded the exercise price. On
July 1, 1996, NorthWestNet adopted Statement of Financial Accounting Standards
(SFAS) No. 123, Accounting for Stock-Based Compensation, which permits entities
to recognize as expense over the vesting period the fair value of all
stock-based awards on the date of grant. Alternatively, SFAS No. 123 allows
entities to continue to apply the provisions of APB Opinion No. 25 for
transactions with employees and provide pro forma net income and pro forma
earnings per share disclosures for employee stock option grants made in 1995 and
future years as if the fair-value-based method defined in SFAS No. 123 had been
applied to these transactions. NorthWestNet has elected to continue to apply the
provisions of APB Opinion No. 25 and provide the pro forma disclosure provisions
of SFAS No. 123.

(4) BORROWING AGREEMENT
 
     NorthWestNet had a borrowing agreement with a commercial bank, which
expired in June 1997, that provided for a $400,000 operating line of credit
(Line of Credit) and a $600,000 equipment term loan (Term Loan). Borrowings
under the Line of Credit were limited to 75% of eligible accounts receivable and
bear interest at the bank's prime rate plus 1.75%. The Term Loan bore interest
at the bank's prime rate plus 2%. Borrowings under this agreement were secured
by substantially all of NorthWestNet's assets. There were no borrowings under
the Line of Credit or Term Loan as of June 30, 1996.
 
(5) INCOME TAXES
 
     The components of NorthWestNet's income tax expense (benefit) for the six
months ended June 30, 1996 and the eight months ended February 28, 1997 are as
follows:

</TABLE>
 
   
     Deferred income taxes result from temporary differences in the recognition
of income and expense between financial statement and income tax reporting.
Temporary differences at June 30, 1996 are primarily attributable to
depreciation and amortization of equipment, furniture and leasehold
improvements. The tax effects of these temporary differences result in deferred
tax assets which are classified as noncurrent on the accompanying June 30, 1996
balance sheet. Actual tax expense for the six months ended June 30, 1996
approximates the amount calculated using the Federal statutory rate of 34%, plus
the provision for state taxes. The tax benefit for the eight months ended
February 28, 1997 differs from the expected benefit, calculated using the
Federal statutory rate of 34%, primarily due to non-deductible stock option
compensation.
    
 
(6) STOCKHOLDERS' EQUITY -- EMPLOYEE STOCK OPTION PLAN
 
     NorthWestNet adopted a stock option plan (Plan) in January 1996 to
compensate its employees for future services and has reserved 1.5 million shares
of common stock for option grants under the Plan. Of the reserved shares,
500,000 are for options which are exercisable, upon reaching defined corporate
objectives (Contingent Options), at an exercise price of $.875 per share. The
date the defined corporate objectives are met, any excess of fair market value
per share over the exercise price per share of the outstanding options would be
charged to salaries and benefits expense in the statement of operations with a
corresponding increase in stockholder's equity. As of December 31, 1996, 370,000
contingent shares were outstanding. The remaining 1 million reserved shares are
for options which generally vest, based on continued employment, over periods
ranging from three to four years in equal monthly increments beginning the month
after the grant (Noncontingent Options). All options expire ten years from the
date of grant and are exercisable at the fair market value of the common stock
at the grant date.

     NorthWestNet applies APB Opinion No. 25 in accounting for its Plans, and,
because the Company grants options at fair value, as determined by the Company's
Board of Directors, no compensation cost has been recognized for its employee
stock options in the financial statements. Had NorthWestNet determined
compensation cost of employee stock options based on the fair value at the grant
date for its stock options under SFAS No. 123, NorthWestNet's net earnings would

THE BOARD OF DIRECTORS
VERIO INC.:
 
     We have audited the accompanying balance sheet of Aimnet Corporation

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.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Aimnet Corporation as of
March 31, 1997, and the results of its operations and its cash flows for the
year ended March 31, 1997 and the period ended May 19, 1997 in conformity with

                     (WHOLLY-OWNED BY AIMQUEST CORPORATION)
 
                         NOTES TO FINANCIAL STATEMENTS
                                 MARCH 31, 1997
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization and Basis of Presentation
 
     Aimnet Corporation (the Company) was incorporated in the State of
California on September 26, 1996 as a wholly owned subsidiary of Aimquest
Corporation (Aimquest). Prior to incorporation, the Company's assets,
liabilities, and operations were included in the financial statements of
Aimquest. The Company provides regional internet access services, and hardware
and software sales to customers in California. The accompanying financial
statements include the operations of the Company assuming that the Company had
been operated separately as of April 1, 1996 and thereafter.
 
     Effective May 19, 1997, Verio Inc. acquired a 55% ownership interest in the
Company (see note 6).
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
 
  Revenue Recognition
 
     Internet services are recognized as the services are provided. The Company
records deferred revenue for amounts billed and/or collected in advance. Revenue
from hardware and software sales is recognized upon shipment of the respective
products.
 
  Inventory
 
     Inventory, consisting of systems hardware and software and maintenance
parts and supplies is recorded at the lower of cost (first-in, first-out) or
market.
 
  Equipment
 
     Equipment, including assets held under capital leases, is stated at cost,
less accumulated depreciation and amortization. Depreciation and amortization is
recorded using the straight-line method over the shorter of the estimated useful
lives of the related assets or the lease term, which are two or three years.
Costs for normal repairs and maintenance are expensed as incurred.
 
  Income Taxes
 
     The Company is included in the tax returns of Aimquest. Income taxes are
accounted for under the provisions of Statement of Financial Accounting
Standards No. 109, Accounting for Income Taxes, (SFAS 109). Under SFAS 109,
deferred income taxes are recognized for the future tax consequences of
differences between the tax bases of assets and liabilities and their financial
reporting amounts at each year-end based on enacted tax laws and statutory rates
applicable to the periods in which the differences are expected to affect
taxable income. Valuation allowances are established, when necessary, to reduce
deferred tax assets to the amount expected to be realized.
 
     No tax benefit has been allocated to the Company due to the Company's net
loss and the uncertainty regarding the ultimate utilization of such loss in the
consolidated income tax returns of Aimquest. A valuation allowance has been
recorded for the entire balance of the deferred tax asset related to the
Company's net loss.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Concentration of Credit Risk and Financial Instruments
 
   
     Statement of Financial Accounting Standards No. 107 requires disclosure
about fair value for all financial instruments whether or not recognized for
financial statement purposes. Management estimates that the fair values of all
financial instruments as of March 31, 1997 approximate their carrying values
based on their terms and interest rates. The use of different market assumptions
and/or estimation methodologies may have a significant effect on the estimated
fair values.
    
 
     Customers who operate in California represent substantially all of the
Company's customer base and accounts receivable. However, no single customer
comprised more than 5% of accounts receivable or total revenue as of or for the
year ended March 31, 1997 or the period ended May 19, 1997.
 
  Long-Lived Assets
 
   
     In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121, Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of (SFAS 121). This
statement was effective for financial statements for fiscal years beginning
after December 15, 1995. Statement No. 121 requires impairment losses to be
recorded on long-lived assets used in operations when indicators of impairment
are present and the undiscounted future cash flows estimated to be generated by
those assets are less than the assets' carrying amount. If such assets are
considered to be impaired, the impairment to be recognized is measured by the
amount by which the carrying amount of the assets exceeds the fair value of the
assets. Assets to be disposed of are reported at the lower of the carrying
amount or fair value, less costs to sell. The adoption of SFAS 121 effective
April 1, 1996 did not have a significant effect on the Company's financial
position or results of operations.
    
 
(2) EQUIPMENT
 
     Equipment consisted of the following at March 31, 1997:

                               SEPTEMBER 30, 1997
    
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization and Basis of Presentation
 
   
     West Coast Online, Inc. (the Company) was incorporated in the State of
California on January 30, 1996. The Company provides internet access services
and computer hardware sales to customers primarily in California.
    
 
   
     As of September 30, 1997, Verio Inc. (Verio) acquired all of the
outstanding common stock of the Company, resulting in 100% ownership.
    
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
 
  Equipment
 
   
     Equipment is stated at cost, less accumulated depreciation. Depreciation is
recorded using the straight-line method over the shorter of the estimated useful
lives of the related assets or the lease term, which range from three to five
years. Costs of normal repairs and maintenance are expensed as incurred.
    
 
  Long-Lived Assets
 
     The Company evaluates the carrying value of its long-lived assets under the
provisions of Statement of Financial Accounting Standards No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of (SFAS 121). SFAS 121 requires impairment losses to be recorded on long-lived
assets used in operations, including goodwill, when indications of impairment
are present and the undiscounted future cash flows estimated to be generated by
those assets are less than the assets' carrying amount. If such assets are
impaired, the impairment to be recognized is measured by the amount by which the
carrying amount of the assets exceeds the estimated fair value of the assets.
Assets to be disposed of are reported at the lower of the carrying value or fair
value, less costs to sell.
 
  Revenue Recognition
 
     Internet services are recognized as the services are provided. The Company
records deferred revenue for amounts billed and/or collected in advance.
 
     Revenue from hardware sales is recognized upon shipment of the respective
products if the Company's future obligations are not significant and
collectibility is probable.
 
  Income Taxes
 
   
     Income taxes are accounted for under the provisions of Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS 109).
Under SFAS 109, deferred income taxes are recognized for the future tax
consequences of differences between the tax bases of assets and liabilities and
their financial reporting amounts at September 30, 1997 based on enacted tax
laws and statutory rates applicable to the periods in which the differences are
expected to affect taxable income. Valuation allowances are established, when
necessary, to reduce deferred tax assets to the amount expected to be realized.
The Company has a net operating loss carryforward of approximately $181,000
which expires in 2012. No tax benefit has been recorded by the Company for the
nine months ended September 30, 1997 due to the Company's net loss and the
uncertainty regarding the ultimate utilization of such loss carryforward. A
valuation allowance has been

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
   
recorded for the entire balance of the deferred tax asset related to the
carryforward. Other temporary differences between financial statement and income
tax bases of assets and liabilities are not significant.
    
 
  Concentration of Credit Risk and Financial Instruments
 
   
     Statement of Financial Accounting Standards No. 107 requires disclosure
about fair value for all financial instruments whether or not recognized for
financial statement purposes. Management estimates that the fair values of all
financial instruments as of December 31, 1997 approximate their carrying values
based on their terms and interest rates. The use of different market assumptions
and/or estimation methodologies may have a significant effect on the estimated
fair values.
    
 
   
     Customers who operate in California represent substantially all of the
Company's customer base. However, no single customer comprised more than 10% of
accounts receivable or total revenue for the nine months ended September 30,
1997.
    
 
(2) EQUIPMENT
 
   
     Equipment consisted of the following at September 30, 1997:

                         NOTES TO FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1997
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization and Basis of Presentation
 
     Clark Internet Services, Inc. (the Company) is a provider of internet
access services to businesses and individuals, primarily in the Maryland,
Washington DC, and Northern Virginia regions.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of revenues and expenses during the
reporting period. Actual results may differ from those estimates.
 
     Effective October 17, 1997, Verio Inc. acquired 51% of the outstanding
common stock of the Company.
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid debt instruments with original
maturities of three months or less to be cash equivalents.
 
  Equipment
 
     Equipment is recorded at cost. Depreciation is provided over the estimated
useful lives of the assets ranging from 3 to 5 years using the straight-line
method.
 
  Long-Lived Assets
 
     The Company evaluates the carrying value of its long-lived assets under the
provisions of Statement of Financial Accounting Standards No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of (Statement No. 121). Statement No. 121 requires impairment losses to be
recorded on long-lived assets used in operations, including goodwill, when
indicators of impairment are present and the undiscounted future cash flows
estimated to be generated by those assets are less than the assets' carrying
amount. If such assets are impaired, the impairment to be recognized is measured
by the amounts by which the carrying amount of the assets exceeds the fair value
of the assets. Assets to be disposed of are reported at the lower of the
carrying value or fair value, less costs to sell.
 
  Revenue Recognition
 
     Internet services revenue is recognized as the services are provided.
Installation charges and set-up fees are recognized when installation is
completed. The Company records deferred revenue for accounts billed and/or
collected in advance.
 
  Income Taxes
 
     The Company accounts for income taxes under the provisions of Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS 109).
SFAS 109 requires recognition of deferred tax liabilities and assets for the
expected future tax consequences of events that have been included in the
financial statements or tax returns. Under this method, deferred tax liabilities
and assets are determined based on the difference between the financial
statement and tax bases of assets and liabilities using enacted tax rates in
effect for the year in which the differences are expected to reverse.
 
     At December 31, 1997, the Company has a net operating loss carryforward for
federal income tax purposes of $235,000 which is available to offset future
federal taxable income, if any, through 2012. Due to the uncertainty regarding
the ultimate utilization of the net operating loss carryforward a valuation
allowance

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
has been recorded for the full amount of the deferred tax asset related to the
net operating loss carryforward, which represents the only significant temporary
difference as of September 30, 1997.
 
  Concentration of Credit Risk and Financial Instruments
 
   
     Statement of Financial Accounting Standards No. 107 requires disclosure
about fair value for all financial instruments whether or not recognized for
financial statements purposes. Management estimates that the fair values of all
financial instruments as of September 30, 1997 approximate their carrying values
based on their terms and interest rates. The use of different market assumptions
and/or estimation methodologies may have a significant effect on the estimated
fair values.
    
 
(2) EQUIPMENT
 
     Equipment consisted of the following at September 30, 1997:

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Verio Inc.:
 
     We have audited the accompanying balance sheets of ATMnet Corporation as of
October 31, 1996 and 1997, and the related statements of operations,
stockholders' deficit, and cash flows for the years then ended. 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.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of ATMnet Corporation as of
October 31, 1996 and 1997, and the results of its operations and its cash flows
for the years then ended in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
                           OCTOBER 31, 1996 AND 1997
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization and Basis of Presentation
 
     ATMnet Corporation (the Company) was incorporated in the State of
California on February 26, 1997. The Company provides regional internet access
services, and hardware sales to customers mainly in California.
 
     Effective November 5, 1997, Verio Inc. acquired substantially all of the
net assets of the Company.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
 
  Revenue Recognition
 
     Internet services are recognized as the services are provided. The Company
records deferred revenue for amounts billed and/or collected in advance. Revenue
from hardware sales is recognized upon shipment of the respective products.
 
  Equipment and Leasehold Improvements
 
     Equipment and leasehold improvements, including assets held under capital
leases, is stated at cost, less accumulated depreciation and amortization.
Depreciation and amortization is recorded using the straight-line method over
the shorter of the estimated useful lives of the related assets or the lease
term, which are two or three years. Costs for normal repairs and maintenance are
expensed as incurred.
 
  Investment in Affiliates
 
     Investment in affiliate represents common stock of an affiliate
representing less than a 20% ownership interest which is accounted for using the
cost method.
 
  Intangible Assets
 
     The excess of cost over the fair value of net assets acquired, or goodwill,
and organization costs are amortized using the straight-line method over five
years.
 
  Income Taxes
 
     Income taxes are accounted for under the provisions of Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS 109).
Under SFAS 109, deferred income taxes are recognized for the future tax
consequences of differences between the tax bases of assets and liabilities and
their financial reporting amounts at each year-end based on enacted tax laws and
statutory rates applicable to the periods in which the differences are expected
to affect taxable income. Valuation allowances are established, when necessary,
to reduce deferred tax assets to the amount expected to be realized.
 
     The Company has a net operating loss carryforward for income tax purposes
of approximately $3,883,000 which expires in 2012. No tax benefit has been
recorded by the Company in fiscal 1996 and 1997 due to the Company's net loss
and the uncertainty regarding the ultimate utilization of such loss
carryforward. A valuation allowance has been recorded for the entire balance of
the deferred tax asset related to the carryforward. Other temporary differences
between financial statement and income tax bases of assets and liabilities are
not significant.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
                           OCTOBER 31, 1996 AND 1997
 
  Concentration of Credit Risk and Financial Instruments
 
   
     Statement of Financial Accounting Standards No. 107 requires disclosure
about fair value for all financial instruments whether or not recognized for
financial statement purposes. Management estimates that the fair values of all
financial instruments as of October 31, 1997 and 1996 approximate their carrying
values based on their terms and interest rates. The use of different market
assumptions and/or estimation methodologies may have a significant effect on the
estimated fair values.
    
 
     Customers who operate in California represent substantially all of the
Company's customer base and accounts receivable. However, no single customer
comprised more than 5% of accounts receivable or total revenue as of or for the
year ended October 31, 1997 or 1996.
 
  Long-Lived Assets
 
     The Company accounts for long-lived assets under the provisions of
Statement of Financial Accounting Standards No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of
(SFAS 121). Statement No. 121 requires impairment losses to be recorded on
long-lived assets used in operations when indicators of impairment are present
and the undiscounted future cash flows estimated to be generated by those assets
are less than the assets' carrying amount. If such assets are considered to be
impaired, the impairment to be recognized is measured by the amount by which the
carrying amount of the assets exceeds the fair value of the assets. Assets to be
disposed of are reported at the lower of the carrying amount or fair value, less
costs to sell.
 
  Stock-Based Compensation
 
     The Company applies APB Opinion 25 and related interpretations in
accounting for its stock compensation plan. Accordingly, since the Company
grants stock options with exercise prices equal to fair value at the date of
grant, no compensation expense has been recognized in 1996 or 1997. Under
Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based
Compensation (SFAS 123), entities are permitted to adopt the fair value method
of accounting for employee stock-based compensation plans. However, SFAS 123
allows an entity to continue using the intrinsic value method under APB Opinion
No. 25, but requires the entity to make pro forma disclosures of net income or
loss as if the fair value method of accounting had been applied.
 
(2) EQUIPMENT AND LEASEHOLD IMPROVEMENTS
 
     Equipment consisted of the following at October 31, 1996 and 1997:

related to the subordinated notes totaled $104,130 in 1997.
 
(5) STOCK COMPENSATION PLANS
 
     The Company established a Stock Option Plan in March 1996, whereby. at the
discretion of the Board of Directors (the Board), the Company may grant stock
options to certain key employees of the Company. The option price is determined
by the Board at the time the option is granted, but in no event is less than the
fair market value of the Company's common stock at the date of grant, as

circumstances, earlier based on the fair value of the Company's common shares,
as defined, and expire ten years from the date of grant. As of October 31, 1997,
no options had been exercised or are exercisable. The weighted-average
contractual life of outstanding options as of October 31, 1997 is approximately
two years.

compensation expense for the years ended October 31, 1996 and 1997 based on the
fair value of the options at the grant dates under SFAS No. 123, net loss would
increase to $1,595,000 and $2,854,000, respectively.

Nebraska in September 1987, as Midnet Inc., a nonprofit corporation organized to
promote research, education and economic development. On July 15, 1994, Midnet
Inc. became a for profit corporation and was purchased by Global Internet.Com
Inc. (Parent) on August 8, 1994. On March 12, 1997, the Company changed its
corporate name from Midnet Inc. to Global Internet Network Services, Inc.
 
     Effective November 26, 1997, Verio Inc. (Verio) acquired a 100% ownership
interest in the Company. (see note 6).
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
 
  Revenue Recognition
 
     Internet services are recognized as the services are provided. The Company
records deferred revenue for amounts billed and/or collected in advance. Revenue
from consulting services is recognized when services have been rendered. Revenue
from hardware and software sales is recognized upon shipment of the respective
products.
 
  Inventory
 
     Inventory, consisting of systems hardware and software and maintenance
parts and supplies is recorded at the lower of cost (first-in, first-out) or
market.
 
  Equipment
 
     Equipment, including any assets held under capital leases, is recorded at
cost, less accumulated depreciation and amortization. Depreciation and
amortization is recorded using the straight-line method over the estimated
useful lives of the related assets or the lease term, which range from three to
five years. Costs for normal repairs and maintenance are expensed as incurred.
 
  Income Taxes
 
     The Company is included in the tax returns of the Parent. Income taxes are
accounted for under the provisions of Statement of Financial Accounting
Standards No. 109, Accounting for Income Taxes (SFAS 109). Under SFAS 109,
deferred income taxes are recognized for the future tax consequences of
differences between the tax bases of assets and liabilities and their financial
reporting amounts at each year-end based on enacted tax laws and statutory rates
applicable to the periods in which the differences are expected to affect
taxable income. Valuation allowances are established, when necessary, to reduce
deferred tax assets to the amount expected to be realized.
 
     The Company has a net operating loss carryforward of approximately
$518,000, which expires in 2012. No tax benefit has been recorded by the Company
for 1996 or 1997 due to the Company's net loss and the uncertainty regarding the
ultimate utilization of such loss in the consolidated income tax returns of the
Parent. A valuation allowance has been recorded for the entire balance of the
deferred tax asset related to the

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
Company's net loss. Other temporary differences between financial statement and
income tax bases of assets and liabilities are not significant.
 
  Concentration of Credit Risk
 
     The Company provides unsecured credit to customers in the normal course of
business. Failure of the customers to pay could result in losses up to the
recorded receivable balances. The Company did not have any customers that
represent greater than 5% of total revenue for the year ended December 31, 1996
and the period ended November 26, 1997, respectively.
 
  Long-Lived Assets
 
     In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121, Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of (SFAS 121). This
statement was effective for financial statements for fiscal years beginning
after December 15, 1995. Statement No. 121 requires impairment losses to be
recorded on long-lived assets used in operations when indicators of impairment
are present and the undiscounted future cash flows estimated to be generated by
those assets are less than the assets' carrying amount. If such assets are
considered to be impaired, the impairment to be recognized is measured by the
amount by which the carrying amount of the assets exceeds the fair value of the
assets. Assets to be disposed of are reported at lower of the carrying amount or
fair value less costs to sell. SFAS 121 did not have a significant effect on the
Company's financial position or results of operations in 1997 and 1996.

The Board of Directors
    
   
Verio Inc.:
    
 
   
     We have audited the accompanying balance sheets of the Pennsylvania
Research Partnership Network (PREPnet) as of November 30, 1996 and 1997, and the
related statements of operations and owners' deficit, and cash flows for the
years then ended and the period ended December 24, 1997. These financial
statements are the responsibility of PREPnet'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.
    
 
   
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the Pennsylvania Research
Partnership Network (PREPnet) as of November 30, 1996 and 1997, and the results
of its operations and its cash flows for the years then ended and for the period
ended December 24, 1997 in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
    
   
                           NOVEMBER 30, 1996 AND 1997
    
 
   
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    
 
   
  Organization and Basis of Presentation
    
 
   
     The accompanying financial statements include the accounts of the
Pennsylvania Research Partnership Network (PREPnet), the data communications
network of a consortium of research institutions in Pennsylvania. A joint
venture between Carnegie Mellon University and the University of Pittsburgh
serves as the legal entity and coordinator of the consortium. The accompanying
financial statements have been prepared assuming that PREPnet had been operated
separately as of December 1, 1995 and thereafter. PREPnet provides internet
services to businesses, educational institutions, not-for-profit organizations,
and individual subscribers.
    
 
   
     Effective December 24, 1997, the net assets of PREPnet were acquired by
Verio Inc. in a purchase business combination.
    
 
   
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
    
 
   
  Revenue Recognition
    
 
   
     Internet services are recognized as the services are provided. PREPnet
records deferred revenue for amounts billed and/or collected in advance.
    
 
   
  Equipment
    
 
   
     Equipment, including any assets held under capital leases, is stated at
cost, less accumulated depreciation. Depreciation is recorded using the
straight-line method over the estimated useful lives of the related assets or
the lease term, which is 3 years. Costs for normal repairs and maintenance are
expensed as incurred.
    
 
   
  Long-Lived Assets
    
 
   
     PREPnet evaluates the carrying value of its long-lived assets under the
provisions of Statement of Financial Accounting Standards No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of (SFAS 121). Statement No. 121 requires impairment losses to be recorded on
long-lived assets used in operations when indicators of impairment are present
and the undiscounted future cash flows estimated to be generated by those assets
are less than the assets' carrying amount. If such assets are impaired, the
impairment to be recognized is measured by the amount by which the carrying
amount of the assets exceeds the fair value of the assets. Assets to be disposed
of are reported at the lower of the carrying amount or fair value less costs to
sell.
    
 
   
  Income Taxes
    
 
   
     The operations of PREPnet are included in the income tax returns of the
joint venture, which is a non-profit entity and is exempt from income taxes.
However, pro forma information has been included in the accompanying statement
of operations to reflect a pro forma adjustment for income tax expense as if
PREPnet had been a separate taxable entity subject to federal and state income
taxes for all periods presented.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
  Concentration of Credit Risk and Financial Instruments
    
 
   
     Statement of Financial Accounting Standards No. 107 requires disclosure
about fair value for all financial instruments whether or not recognized for
financial statements purposes. Management estimates that the fair values of all
financial instruments as of November 30, 1996 and 1997 approximate their
carrying values based on their terms and interest rates. The use of different
market assumptions and/or estimation methodologies may have a significant effect
on the estimated fair values.

The Board of Directors
    
   
Verio Inc.:
    
 
   
     We have audited the accompanying balance sheets of Monumental Network
Systems, Inc. as of December 31, 1996 and 1997, and the related statements of
operations, stockholders' deficit, and cash flows for the years then ended.
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.
    
 
   
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Monumental Network Systems,
Inc. as of December 31, 1996 and 1997, and the results of its operations and its
cash flows for the years then ended in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
    
   
                           DECEMBER 31, 1996 AND 1997
    
 
   
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    
 
   
  Organization and Basis of Presentation
    
 
   
     Monumental Network Systems, Inc. (the Company) was incorporated in the
State of Virginia on April 13, 1994. The Company's business consists of
providing regional internet access services, hardware and software sales, and
consulting to customers in Virginia, Maryland and the Washington D.C. area.
    
 
   
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
    
 
   
     Effective December 31, 1997, Verio Inc. acquired all of the outstanding
common stock of the Company.
    
 
   
  Equipment
    
 
   
     Equipment, including any assets held under capital leases, is stated at
cost, less accumulated depreciation. Depreciation is recorded using the
straight-line method over the estimated useful lives of the related assets, or
over the lease term, which range from three to seven years. Costs for normal
repairs and maintenance are expensed as incurred.
    
 
   
  Long-Lived Assets
    
 
   
     The Company evaluates the carrying value of its long-lived assets under the
provisions of Statement of Financial Accounting Standards No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of (SFAS 121). Statement No. 121 requires impairment losses to be recorded on
long-lived assets used in operations when indicators of impairment are present
and the undiscounted future cash flows estimated to be generated by those assets
are less than the assets' carrying amount. If such assets are considered to be
impaired, the impairment to be recognized is measured by the amount by which the
carrying amount of the assets exceeds the fair value of the assets. Assets to be
disposed of are reported at lower of the carrying amount or fair value less
costs to sell.
    
 
   
  Revenue Recognition
    
 
   
     Internet services are recognized as the services are provided. The Company
records deferred revenue for amounts billed and/or collected in advance.
    
 
   
     Revenue from consulting services is recognized when services have been
rendered.
    
 
   
     Revenue from hardware and software sales is recognized upon shipment of the
respective products, if significant future vendor obligations do not exist and
collectibility is probable.
    
 
   
  Income Taxes
    
 
   
     Income taxes are accounted for under the provisions of Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS 109).
Under SFAS 109, deferred income taxes are recognized for the future tax
consequences of differences between the tax bases of assets and liabilities and
their financial reporting amounts at each year-end based on enacted tax laws and
statutory rates applicable to the periods in which the differences are expected
to affect taxable income. Valuation allowances are established, when necessary,
to reduce deferred tax assets to the amount expected to be realized.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
  Concentration of Credit Risk and Financial Instruments
    
 
   
     Statement of Financial Accounting Standards No. 107 requires disclosure
about fair value for all financial instruments whether or not recognized for
financial statement purposes. Management estimates that the fair values of all
financial instruments as of December 31, 1996 and 1997 approximate their
carrying values based on their terms and interest rates. The use of different
market assumptions and/or estimation methodologies may have a significant effect
on the estimated fair values.
    
 
   
     Customers who operate in Virginia, Maryland and the Washington D.C. area
represent substantially all of the Company's customer base. No single customer
comprised more than 10% of accounts receivable or total revenue as of or for the
years ended December 31, 1996 or 1997.
    
 
   
  Stock-Based Compensation
    
 
   
     The Company accounts for its stock-based employee compensation plan using
the intrinsic value based method prescribed by Accounting Principles Board
Opinion No. 25, Accounting for Stock Issued to Employees, and related
interpretations (APB 25). The Company has provided pro forma disclosures of net
loss as if the fair value based method of accounting for the plan, as prescribed
by Statement of Financial Accounting Standards No. 123, Accounting for
Stock-Based Compensation (SFAS 123), had been applied. Pro forma disclosures
include the effects of employee stock options granted during the years ended
December 31, 1996 and 1997.
    
 
   
(2) EQUIPMENT
    
 
   
     Equipment consisted of the following at December 31:

(5) INCOME TAXES
    
 
   
     As of December 31, 1997, the Company has a net operating loss carryforward
of approximately $470,000 which will expire in 2012, if not utilized. A
valuation allowance has been recorded for the entire deferred tax asset related
primarily to the net operating loss carryforward due to the uncertainty relating
to the realization of the benefit of the deferred tax asset in the future.
    
 
   
(6) STOCK OPTION PLAN
    
 
   
     The Company's 1997 Option Plan (the Plan) was adopted by the Board of
Directors and approved by the stockholders of the Company on January 1, 1997.
The Plan provides that salaried officers or key employees, non-employee
directors, and consultants who provide services to the Company may, at the
discretion of the plan administrator, be granted Incentive or Non-statutory
stock options to purchase shares of common stock. 200,000 shares of the
Company's common stock have been authorized for issuance under the Plan, of
which 11,872 incentive stock options were granted in 1997, with an exercise
price of $2.00 per share. None of the options were exercised or canceled during
1997.
    
 
   
     Options vest 25% on the first anniversary of the option grant date and 25%
on each of the following three anniversary dates. As of December 31, 1997, no
options were vested or exercisable. The weighted average contractual term of
outstanding options was approximately 9 years at December 31, 1997.
    
 
   
     The per share weighted-average fair value of stock options granted was $.33
on the date of grant using the Black-Scholes option-pricing model with the
following weighted-average assumptions; expected dividend yield

0%, risk-free interest rate of 6%, and expected life of three years. If the
Company determined compensation expense in 1997 based on the fair value of the
options at the grant date under SFAS No. 123, net loss would not have been
significantly different from the historical results of operations other than for
compensation expense recognized for options granted at less than fair value, as
discussed below.
    
 
   
     None of the incentive stock option shares were exercisable or vested as of
December 31, 1997. However, in accordance with the acquisition agreement between
the Company and Verio Inc., Monumental Network Systems, Inc. purchased the
11,872 options outstanding as of December 31,1997 at fair market value, less the
exercise price per share, and recorded a charge to operations of $84,152.

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

We believe that our audits provide a reasonable basis for our opinion.
    
 
   
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Internet Servers, Inc. as of

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    
 
   
  Organization and Basis of Presentation
    
 
   
     Internet Servers, Inc. (the Company) was incorporated in the State of Utah
on August 23, 1995. The Company's business consists of providing regional
internet enhanced services and consulting to customers in Utah and throughout
the Western states.
    
 
   
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
    
 
   
     Effective December 31, 1997, Verio Inc. acquired 100% of the outstanding
common stock of the Company.
    
 
   
  Cash and Cash Equivalents
    
 
   
     The Company considers all highly liquid investments with original
maturities of three months or less to be cash equivalents.
    
 
   
  Revenue Recognition
    
 
   
     Revenue related to enhanced and internet services is recognized as the
services are provided. Enhanced services consists primarily of web hosting
services to customers. The Company records deferred revenue for accounts billed
and/or collected in advance.
    
 
   
     Revenue from hardware and software sales is recognized upon shipment of the
respective products if the Company's future obligations are not significant and
collectibility is probable.
    
 
   
  Equipment
    
 
   
     Equipment is stated at cost, less accumulated depreciation. Depreciation is
provided over the estimated useful lives of the assets ranging from three to
seven years using the straight-line method. Costs for normal repairs and
maintenance are expensed as incurred.
    
 
   
  Long-Lived Assets
    
 
   
     The Company evaluates the carrying value of its long-lived assets under the
provisions of Statement of Financial Accounting Standards No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of (SFAS 121). SFAS 121 requires impairment losses to be recorded on long-lived
assets used in operations including goodwill when indications of impairment are
present and the undiscounted future cash flows estimated to be generated by
those assets are less than the assets' carrying amount. If such assets are
impaired the impairment to be recognized is measured by the amount by which the
carrying amount of the assets exceeds the estimated fair value of the assets.
Assets to be disposed of are reported at the lower of the carrying value or fair
value less costs to sell.
    
 
   
  Income Taxes
    
 
   
     From inception to September 1, 1996, the Company elected to be treated as a
subchapter S Corporation for income tax purposes. Accordingly, taxable income
through September 1, 1996 was included in the income tax returns of the
shareholders. On September 1, 1996, the Company converted to a C Corporation.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
     The Company accounts for income taxes under the provisions of Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS 109).
SFAS 109 requires recognition of deferred tax liabilities and assets for the
expected future tax consequences of events that have been included in the
financial statements or tax returns. Under this method deferred tax liabilities
and assets are determined based on the difference between the financial
statement and tax bases of assets and liabilities using enacted tax rates in
effect for the year in which the difference is expected to reverse.
    
 
   
  Concentration of Credit Risk and Financial Instruments
    
 
   
     Statement of Financial Accounting Standards No. 107 requires disclosure
about fair value for all financial instruments whether or not recognized for
financial statement purposes. Management estimates that the fair values of all
financial instruments as of December 31, 1996 and 1997 approximate their
carrying values based on their terms and interest rates. The use of different
market assumptions and/or estimation methodologies may have a significant effect
on the estimated fair values.
    
 
   
     Customers who operate in Utah represent substantially all of the Company's
customer base and accounts receivable. However, no single customer comprised
more than 10% of accounts receivable or total revenue as of or for the years
ended December 31, 1995, 1996 or 1997.
    
 
   
(2) EQUIPMENT
    
 
   
     Equipment consisted of the following at December 31:

     We have audited the accompanying balance sheets of NSNet, Inc. as of
December 31, 1996 and 1997, and the related statements of operations, owner's
and stockholder's equity, and cash flows for the years then ended. 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.
    
 
   
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of NSNet, Inc. as of December
31, 1996 and 1997, and the results of its operations and its cash flows for the
years then ended in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
    
   
                           DECEMBER 31, 1996 AND 1997
    
 
   
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    
 
   
  Organization and Basis of Presentation
    
 
   
     NSNet, Inc. (the Company) was incorporated as a subchapter S Corporation in
the State of California on January 1, 1997. Prior to incorporation, the Company
was operating as NextGen Systems Internet Services, a sole proprietorship formed
in 1992. All assets and liabilities of the sole proprietorship were contributed
to the Company upon incorporation and recorded at historical cost. The Company
provides internet access services to customers in California.
    
 
   
     Effective February 27, 1998, Verio Inc. acquired 100% of the outstanding
common stock of the Company.
    
 
   
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
    
 
   
  Revenue Recognition
    
 
   
     Internet services are recognized as the services are provided. The Company
records deferred revenue for accounts billed and/or collected in advance.
    
 
   
  Equipment
    
 
   
     Equipment, including assets held under capital leases, is stated at cost,
less accumulated depreciation. Depreciation is recorded using the straight-line
method over the shorter of the estimated useful lives of the related assets or
the lease term, which is three years. Costs for normal repairs and maintenance
are expensed as incurred.
    
 
   
  Long-Lived Assets
    
 
   
     The Company evaluates the carrying value of its long-lived assets under the
provisions of Statement of Financial Accounting Standards No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of (SFAS 121). SFAS 121 requires impairment losses to be recorded on long-lived
assets used in operations, including goodwill, when indications of impairment
are present and the undiscounted future cash flows estimated to be generated by
those assets are less than the assets' carrying amount. If such assets are
impaired, the impairment to be recognized is measured by the amount by which the
carrying amount of the assets exceeds the estimated fair value of the assets.
Assets to be disposed of are reported at the lower of the carrying value or fair

  Income Taxes
    
 
   
     No provision for income taxes has been included in the accompanying
financial statement for 1996 or 1997 due to the Company's status as a sole
proprietorship and subchapter S Corporation. Accordingly, net earnings as of
December 31, 1996 were included in owner's equity and taxable income has been
included in the tax returns of the owner and stockholder. However, pro forma
information has been included in the accompanying statements of operations to
reflect a pro forma adjustment for income tax expense as if the Company had been
a separate taxable entity subject to federal and state income taxes for both
years presented.

their carrying values based on their terms and interest rates. The use of
different market assumptions and/or estimation methodologies may have a
significant effect on the estimated fair values.

The Board of Directors
Verio Inc.:
 
   
     We have audited the accompanying balance sheet of Access One, Inc. as of

misstatement. An audit includes examining, on a test basis, evidence supporting

assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

                               DECEMBER 31, 1997
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization and Basis of Presentation
 
   
     Access One, Inc. (the Company) was originally organized as a limited
liability company on July 1, 1994. The Company reincorporated on December 9,
1996 as a C corporation in the state of Washington. The Company provides
internet access and enhanced services and computer hardware and software sales
to customers primarily in Washington.
    
 
   
     Effective February 27, 1998, Verio Inc. (Verio) acquired all of the
outstanding common stock of the Company, resulting in 100% ownership (see Note
6).
    
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
 
  Equipment
 
   
     Equipment is stated at cost, less accumulated depreciation. Depreciation is
recorded using the straight-line method over the shorter of the estimated useful
lives of the related assets or the lease terms, which range from three to five
years. Costs for normal repairs and maintenance are expensed as incurred.
    
 
  Long-Lived Assets
 
     The Company evaluates the carrying value of its long-lived assets under the
provisions of Statement of Financial Accounting Standards No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of (SFAS 121). SFAS 121 requires impairment losses to be recorded on long-lived
assets used in operations, including goodwill, when indications of impairment
are present and the undiscounted future cash flows estimated to be generated by
those assets are less than the assets' carrying amount. If such assets are
impaired, the impairment to be recognized is measured by the amount by which the
carrying amount of the assets exceeds the estimated fair value of the assets.
Assets to be disposed of are reported at the lower of the carrying value or fair
value, less costs to sell.
 
  Revenue Recognition
 
   
     Internet and enhanced services are recognized as the services are provided.
Enhanced services consist primarily of web hosting and collocation services to
customers. The Company records deferred revenue for amounts billed and/or
collected in advance.
    
 
     Revenue from hardware sales is recognized upon shipment of the respective
products if the Company's future obligations are not significant and
collectibility is probable.
 
  Income Taxes
 
   
     Income taxes are accounted for under the provisions of Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS 109).
Under SFAS 109, deferred income taxes are recognized for the future tax
consequences of differences between the tax bases of assets and liabilities and
their financial reporting amounts at each year-end based on enacted tax laws and
statutory rates applicable to the periods in which the differences are expected
to affect taxable income. Valuation allowances are established, when necessary,
to reduce deferred tax assets to the amount expected to be realized.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
   
     The Company has a net operating loss carryforward for income tax purposes
of approximately $337,000 which expires in 2012. No tax benefit has been
recorded by the Company in 1997 due to the Company's net loss and the
uncertainty regarding the ultimate utilization of such loss carryforward. The
Company also has a deferred tax asset related to the allowance for doubtful
accounts of approximately $56,000. A valuation allowance has been recorded for
the entire balance of the deferred tax asset related to the carryforward and the
allowance for doubtful accounts. Other temporary differences between financial
statement and income tax bases of assets and liabilities are not significant.
    
 
  Concentration of Credit Risk and Financial Instruments
 
   
     Statement of Financial Accounting Standards No. 107 requires disclosure
about fair value for all financial instruments whether or not recognized for
financial statement purposes. Management estimates that the fair values of all
financial instruments as of December 31, 1997 approximate their carrying values
based on their terms and interest rates. The use of different market assumptions
and/or estimation methodologies may have a significant effect on the estimated
fair values.
    
 
   
     Customers who operate in Washington represent substantially all of the
Company's customer base. No single customer comprised more than 10% of revenue
or accounts receivable as of or for the year ended December 31, 1997.

opinion on these financial statements based on our audit.
    
 
     We conducted our audit 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 audit provides a reasonable basis for our opinion.
 
   
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of STARnet, L.L.C. as of
December 31, 1997, and the results of its operations and its cash flows for the

1994. On August 18, 1997, the Company changed its name to STARnet, L.L.C. The
Company provides internet access services and computer hardware sales to
customers primarily in Missouri and Illinois.
    
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
 
  Equipment
 
     Equipment is stated at cost, less accumulated depreciation. Depreciation is
recorded using a method that estimates the straight-line method over the
estimated useful lives of the related assets, which is three years. Costs for
normal repairs and maintenance are expensed as incurred.
 
  Long-Lived Assets
 
     The Company evaluates the carrying value of its long-lived assets under the
provisions of Statement of Financial Accounting Standards No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of (SFAS 121). SFAS 121 requires impairment losses to be recorded on long-lived
assets used in operations, including goodwill, when indications of impairment
are present and the undiscounted future cash flows estimated to be generated by
those assets are less than the assets' carrying amount. If such assets are
impaired, the impairment to be recognized is measured by the amount by which the
carrying amount of the assets exceeds the estimated fair value of the assets.
Assets to be disposed of are reported at the lower of the carrying value or fair
value, less costs to sell.
 
  Revenue Recognition
 
     Internet services are recognized as the services are provided. The Company
records deferred revenue for amounts billed and/or collected in advance.
 
     Revenue from hardware sales is recognized upon shipment of the respective
products if the Company's future obligations are not significant and
collectibility is probable.
 
  Income Taxes
 
     No provision for income taxes has been included in the accompanying
financial statements due to the Company's status as a limited liability
corporation. Accordingly, taxable income has been included in the tax returns of
the members. However, pro forma information has been included in the
accompanying statement of operations to reflect a pro forma adjustment for
income tax expense as if the Company had been a separate taxable entity subject
to federal and state income taxes for the year ended December 31, 1997.
 
  Concentration of Credit Risk and Financial Instruments
 
   
     Statement of Financial Accounting Standards No. 107 requires disclosure
about fair value for all financial instruments whether or not recognized for
financial statement purposes. Management estimates that the fair values of all
financial instruments as of December 31, 1997 approximate their carrying values
based on their

terms and interest rates. The use of different market assumptions and/or
estimation methodologies may have a significant effect on the estimated fair
values.
 
     Customers who operate in Missouri and Illinois represent substantially all
of the Company's customer base. Three customers comprised approximately 38% of
accounts receivable as of December 31, 1997. However, no single customer
comprised more than 10% of revenue for the year ended December 31, 1997.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1996 AND 1997
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization and Basis of Presentation
 
   
     Computing Engineers Inc. (the Company) was incorporated in the State of
Illinois on November 1, 1993. The Company is a provider of internet access
services to businesses and individuals, primarily in Illinois.
    
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
 
  Equipment
 
     Equipment, including any assets held under capital leases, is stated at
cost, less accumulated depreciation and amortization. Depreciation and
amortization is recorded using the straight-line method over the shorter of the
estimated useful lives of the related assets or the lease term, which is three
years. Costs for normal repairs and maintenance are expensed as incurred.
 
  Long-Lived Assets
 
   
     The Company evaluates the carrying value of its long-lived assets under the
provisions of Statement of Financial Accounting Standards No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of (SFAS 121). Statement No. 121 requires impairment losses to be recorded on
long-lived assets used in operations when indicators of impairment are present
and the undiscounted future cash flows estimated to be generated by those assets
are less than the assets' carrying amount. If such assets are considered to be
impaired, the impairment to be recognized is measured by the amount by which the
carrying amount of the assets exceeds the fair value of the assets. Assets to be
disposed of are reported at lower of the carrying amount or fair value less
costs to sell.
    
 
  Revenue Recognition
 
     Internet services are recognized as the services are provided. The Company
records deferred revenue for amounts billed and/or collected in advance.
 
     Revenue from consulting services is recognized when services have been
rendered.
 
     Revenue from hardware and software sales is recognized upon shipment of the
respective products if the Company's future obligations are not significant and
collectibility is probable.
 
  Income Taxes
 
     No provision for income taxes has been included in the accompanying
financial statements for 1996 or 1997 due to the Company's status as a
subchapter S corporation. Accordingly, taxable income has been included in the
tax returns of the stockholders. However, pro forma information has been
included in the accompanying statements of operations to reflect a pro forma
adjustment for income tax expense as if the Company had been a separate taxable
entity subject to federal and state income taxes for all periods presented.
 
  Concentration of Credit Risk and Financial Instruments
 
   
     Statement of Financial Accounting Standards No. 107 requires disclosure
about fair value for all financial instruments whether or not recognized for
financial statement purposes. Management estimates that the fair values of all
financial instruments as of December 31, 1996 and 1997 approximate their
carrying values based

on their terms and interest rates. The use of different market assumptions
and/or estimation methodologies may have a significant effect on the estimated
fair values.

LI Net, Inc.:
 
   
     We have audited the accompanying balance sheets of LI Net, Inc. as of April

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.
 
   
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of LI Net, Inc. as of April 30,

   YEARS ENDED APRIL 30, 1996 AND 1997 AND NINE MONTHS ENDED JANUARY 31, 1998
    
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization and Basis of Presentation
 
   
     LI Net, Inc. (the Company) was incorporated in the State of New York and
provides regional internet access services to customers in New York.
    
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
 
  Equipment
 
     Equipment, including assets held under capital leases, is stated at cost,
less accumulated depreciation. Depreciation is recorded using the straight-line
method over the shorter of the estimated useful lives of the related assets or
the lease terms, which range from three to five years. Costs for normal repairs
and maintenance are expensed as incurred.
 
  Long-Lived Assets
 
     The Company evaluates the carrying value of its long-lived assets under the
provisions of Statement of Financial Accounting Standards No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of (SFAS 121). SFAS 121 requires impairment losses to be recorded on long-lived
assets used in operations, including goodwill, when indications of impairment
are present and the undiscounted future cash flows estimated to be generated by
those assets are less than the assets' carrying amount. If such assets are
impaired, the impairment to be recognized is measured by the amount by which the
carrying amount of the assets exceeds the estimated fair value of the assets.
Assets to be disposed of are reported at the lower of the carrying value or fair
value, less costs to sell.
 
  Revenue Recognition
 
     Internet services are recognized as the services are provided. The Company
records deferred revenue for amounts billed and/or collected in advance.
 
     Revenue from hardware sales is recognized upon shipment of the respective
products if the Company's future obligations are not significant and
collectibility is probable.
 
  Income Taxes
 
     Income taxes are accounted for under the provisions of Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes, (SFAS 109).
Under SFAS 109, deferred income taxes are recognized for the future tax
consequences of differences between the tax bases of assets and liabilities and
their financial reporting amounts at each year-end based on enacted tax laws and
statutory rates applicable to the periods in which the differences are expected
to affect taxable income. Valuation allowances are established, when necessary,
to reduce deferred tax assets to the amount expected to be realized.
 
  Concentration of Credit Risk and Financial Instruments
 
   
     Statement of Financial Accounting Standards No. 107 requires disclosure
about fair value for all financial instruments whether or not recognized for
financial statement purposes. Management estimates that the fair values of all
financial instruments as of April 30, 1997 and January 31, 1998, approximate
their carrying values

based on their terms and interest rates. The use of different market assumptions
and/or estimation methodologies may have a significant effect on the estimated
fair values.

ITEM 22. UNDERTAKINGS.
 
     (a) Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended (the "Act") may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the provisions described in
Item 20 above, or otherwise, the Registrant has been advised that in the opinion
of the Commission such indemnification is against public policy as expressed in
the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

     (2) The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Act, the
     information omitted from the form of prospectus filed as part of this
     Registration Statement in reliance upon Rule 430A and contained in a form
     of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
     497(h) under the Act shall be deemed to be part of this Registration
     Statement as of the time it was declared effective.
 
          (3) For the purpose of determining any liability under the Act, each
     post-effective amendment that contains a form of prospectus shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
 
     (c) 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.
 
     (d) The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.
 
   
     (e) 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 this 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 this 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) if, in the aggregate, the
        changes in volume and price represent no more than a 20 percent 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 this Registration Statement
        or any material change to such information in this Registration
        Statement.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Verio Inc.:
 
     Under date of February 25, 1998, we reported on the consolidated balance
sheets of Verio Inc. and subsidiaries as of December 31, 1996 and 1997, and the
related consolidated statements of operations, stockholders' deficit, and cash
flows for the period from inception (March 1, 1996) to December 31, 1996 and the
year ended December 31, 1997, which are included in the prospectus. In
connection with our audits of the aforementioned consolidated financial
statements, we also audited the related consolidated financial statement
schedule in the registration statement. This financial statement schedule is the
responsibility of the Company's management. Our responsibility is to express an
opinion on this financial statement schedule based on our audits.
 
     In our opinion, such financial statement schedule, when considered in
relation to the basic consolidated financial statements taken as a whole,
presents fairly, in all material respects, the information set forth therein.

severally and not jointly, to Salomon Brothers Inc, Lazard Freres & Co. LLC,
Chase Securities Inc. and BancBoston Securities Inc.(together, the "Initial
Purchasers") $175,000,000 principal amount of its 10-3/8 % Senior Notes Due 2005
(the "Securities") as set forth on Schedule I hereto, to be issued under an
indenture (the "Indenture") dated as of March 25, 1998 between the Company and
First Trust National Association, as trustee (the "Trustee").

         The sale of the Securities to the Initial Purchasers will be made
without registration of the Securities under the Securities Act of 1933, as
amended (the "Securities Act"), in reliance upon exemptions from the
registration requirements of the Securities Act. The Initial Purchasers have
advised the Company that the Initial Purchasers will offer and sell the
Securities purchased by them hereunder in accordance with Section 4 of this
agreement (this "Agreement" or the "Purchase Agreement") as soon as they deem
advisable.

         In connection with the sale of the Securities, the Company has prepared
a preliminary offering memorandum, dated March 4, 1998 (including any and all
exhibits thereto and any information incorporated by reference therein, the
"Preliminary Memorandum"), and a final offering memorandum, dated March 19, 1998
(the "Final Memorandum"). Each of the Preliminary Memorandum and the Final
Memorandum sets forth certain information concerning the Company and the
Securities. The Company hereby confirms that it has authorized the use of the
Preliminary Memorandum




<PAGE>   2

and the Final Memorandum, and any amendment or supplement thereto, in connection
with the offer and sale of the Securities by the Initial Purchasers. Unless
stated to the contrary, all references herein to the Final Memorandum are to the
Final Memorandum at the Execution Time (as defined below) and are not meant to
include any amendment or supplement subsequent to the Execution Time.

         The holders of the Securities will be entitled to the benefits of the
Registration Agreement dated as of March 25, 1998, between the Company and the
Initial Purchasers (the "Registration Agreement").

         This Agreement, the Indenture, the Securities and the Registration
Agreement are referred to herein as the "Transaction Documents".

         Capitalized terms used herein without definitions have the respective
meanings assigned to them in the Final Memorandum.

         1. Representations and Warranties of the Company. The Company
represents and warrants to, and agrees with, each Initial Purchaser as set forth
below in this Section 1.

         (a) The Preliminary Memorandum, at the date thereof, did not contain
     any untrue statement of a material fact or omit to state any material fact
     necessary to make the statements therein, in the light of the circumstances
     under which they were made, not misleading. The Final Memorandum, at the
     date hereof, does not, and at the Closing Date (as defined below) will not
     (and any amendment or supplement thereto, at the date thereof and at the
     Closing Date, will not), contain any untrue statement of a material fact or
     omit to state any material fact necessary to make the statements therein,
     in the light of the circumstances under which they were made, not
     misleading; provided, -------- however, that the Company makes no
     representation or warranty as to the information contained in or -------
     omitted from the Preliminary Memorandum or the Final Memorandum, or any
     amendment or supplement thereto, in reliance upon and in conformity with
     information furnished in writing to the Company by or on behalf of the
     Initial Purchasers specifically for inclusion therein.


                                      -2-
<PAGE>   3

         (b) The Company has been advised by the National Association of
     Securities Dealers, Inc. PORTAL Market that the Securities have been
     designated PORTAL eligible securities in accordance with the rules and
     regulations of the National Association of Securities Dealers, Inc. (the
     "NASD").

         (c) None of the Company nor any of its Affiliates (as defined in Rule
     501(b) under the Securities Act) has, directly or through any agent, sold,
     offered for sale, solicited offers to buy or otherwise negotiated in
     respect of, any security (as defined in the Securities Act) which could be
     integrated with the sale of the Securities in a manner that would require
     the registration of the Securities under the Securities Act.

         (d) None of the Company nor any of its Affiliates (as defined in Rule
     501(b) under the Securities Act) or any person (other than the Initial
     Purchasers, as to whom the Company makes no representation) acting at the
     request of the Company has engaged, in connection with the offering of the
     Securities, (A) in any form of general solicitation or general advertising
     within the meaning of Rule 502(c) under the Securities Act, (B) in any
     directed selling efforts within the meaning of Rule 902 under the
     Securities Act in the United States in connection with the Securities being
     offered and sold pursuant to Regulation S under the Securities Act, (C) in
     any manner involving a public offering within the meaning of Section 4(2)
     of the Securities Act or (D) in any action which would require the
     registration of the offering and sale of the Securities pursuant to this
     Agreement or which would violate applicable state securities or "blue sky"
     laws.

         (e) Assuming that the representations and warranties of the Initial
     Purchasers contained in Section 4 are true, correct and complete, and
     assuming compliance by the Initial Purchasers with their covenants in
     Section 4, and assuming that the representations and warranties deemed to
     be made by non-U.S. persons and "qualified institutional buyers" ("QIBs")
     (as defined in Rule 144A under the Securities Act) purchasing Securities
     are true and correct as of the Closing Date, it is not necessary in
     connection with the offer, sale and delivery of the Securities to the
     Initial Purchasers in the manner contemplated by, or in connection with the
     initial resale of such Securities by the Initial Purchasers in accordance
     with, this Agreement to register the Securities under the Securities Act or
     to

     qualify any indenture in respect of the Securities under the Trust
     Indenture Act of 1939, as amended (the "Trust Indenture Act").

         (f) The subsidiaries of the Company listed on Schedule II hereto (also
     referred to herein as the "Subsidiaries") are the only subsidiaries of the
     Company that constitute "significant subsidiaries" within the meaning of
     Rule 1-02(w) of Regulation S-X under the Securities Act. Each of the
     Company and the Subsidiaries has been duly organized or incorporated, as
     the case may be, and is validly existing and in good standing under the
     laws of its jurisdiction of organization or incorporation, with all
     requisite power and authority under such laws (a) to own, lease and operate
     their respective properties and to conduct their respective businesses as
     now conducted and as described in the Final Memorandum and (b) to enter
     into, deliver, incur and perform their respective obligations under the
     Transaction Documents, except, in the case of the foregoing subclause (a)
     for authorizations, approvals, orders, leases, certificates and permits,
     the failure of which to possess could not reasonably be expected to have a
     Material Adverse Effect (as defined below); and are all duly qualified to
     do business as foreign partnerships or corporations in good standing in all
     other jurisdictions where the ownership or leasing of their respective
     properties or the conduct of their respective businesses requires such
     qualification, except where the failure to be so qualified could not
     reasonably be expected to have a material adverse effect (i) on the
     business, condition (financial or otherwise), results of operations,
     business affairs or business prospects of the Company and the Subsidiaries
     taken as a whole or (ii) on the ability of the Company to perform any of
     its obligations under the Transaction Documents or to consummate any of the
     transactions contemplated hereby or thereby (a "Material Adverse Effect").
     The Company has no ISP affiliates (other than the Subsidiaries) that would
     individually constitute a "significant subsidiary" of the Company within
     the meaning of Rule 1-02(w) of Regulation S-X under the Securities Act, if
     any such ISP affiliate were a subsidiary of the Company.

         (g) The Securities, the Exchange Notes and the Private Exchange Notes
     have been duly authorized by the Company, and the Company has all requisite
     corporate power and authority to execute, issue and deliver the Securities,
     the Exchange Notes and the Private Exchange Notes 


                                      -4-
<PAGE>   5

     and to incur and perform its obligations provided for therein.

         (h) The Securities, when executed, authenticated and issued in
     accordance with the terms of the Indenture (assuming the due authorization,
     execution and delivery of the Indenture by the Trustee) and when delivered
     against payment of the purchase price therefor as provided in this
     Agreement, will constitute valid and binding obligations of the Company,
     entitled to the benefits of the Indenture and enforceable against the
     Company in accordance with the terms thereof; and the Exchange Notes and
     the Private Exchange Notes, if any, when executed, authenticated, issued
     and delivered by the Company in exchange for the Securities in accordance
     with the terms of the Registration Agreement, will constitute valid and
     binding obligations of the Company, entitled to the benefits of the
     Indenture and enforceable against the Company in accordance with the terms
     thereof; subject, in the case of each of the foregoing, to (a) applicable
     bankruptcy, insolvency, reorganization, moratorium and similar laws

     Company (assuming the due authorization, execution and delivery by parties
     thereto other than the Company), as of the Closing Date, the Indenture and
     the Registration Agreement will constitute the valid and binding
     obligations of the Company, enforceable against the Company in accordance
     with the terms hereof or thereof, subject only to the Enforceability
     Limitations and except that the waiver of stay or extension laws contained
     in Section 5.15 of the Indenture may be unenforceable.

         (j) No consent, waiver, authorization, approval, license, qualification

     and sale of the Securities or the Exchange Notes or the Private Exchange
     Notes, if any, the performance by the Company of its obligations under the
     Transaction Documents, or for the consummation of any of the transactions
     contemplated hereby or thereby, including, without limitation, the issuance
     and sale of the Securities hereunder, except such as may be required (A) in
     connection with the registration under the Securities Act of the Exchange

     Registration Agreement and the consummation by the Company of the
     transactions contemplated hereby, thereby and in the Final Memorandum and
     the compliance by the Company with the terms of the foregoing do not, and,
     at the Closing Date, will not conflict with or constitute or result in a
     breach or violation by the Company or any of the Subsidiaries of (A) any of
     the terms or provisions of, or constitute a default (or an event which,
     with notice or lapse of time or both, would constitute a default) by any of
     the Company or the Subsidiaries or give rise to any right to accelerate the
     maturity or require the prepayment of any indebtedness under, or result in
     the creation or imposition of any lien, charge or encumbrance upon any
     property or assets of the Company or the Subsidiaries under any contract,
     indenture, mortgage, deed of trust, loan agreement, note, lease, license,
     franchise agreement, authorization, permit, certificate or other agreement
     or document to which any of the Company or the Subsidiaries is a party or
     by which any of them may be bound, or to which any of them or any of their
     respective assets or businesses is subject (collectively, "Contracts") (and
     the Company has no knowledge of any conflict, breach or violation of such
     terms or provisions or of any such default, in any such case, which has
     occurred or will so result), (B) the articles or by-laws (each, an
     "Organizational Document") of each of the Company and the Subsidiaries or
     (C) any law, statute, rule or regulation, or any judgment, decree or order,
     in any 


                                      -6-
<PAGE>   7

     such case, of any domestic or foreign court or governmental or regulatory
     agency or other body having jurisdiction over the Company or any of the
     Subsidiaries or any of their respective properties or assets. Schedule III
     hereto lists each Contract with respect to which any conflict, breach or
     violation of the terms or provisions thereof or any default with respect
     thereto could have a Material Adverse Effect (each such Contract being
     referred to herein as a "Material Contract").

         (l) The Securities, the Exchange Notes, the Private Exchange Notes, the
     Indenture and the Registration Agreement will each conform in all material
     respects to the descriptions thereof in the Final Memorandum.

         (m) The audited consolidated financial statements included in the Final
     Memorandum, including the notes thereto, respectively present fairly the
     financial position of each of the Company and its consolidated
     subsidiaries, On-Ramp Technologies, Inc., Global Enterprise
     Services-Network division, Compute Intensive Inc., NorthWestNet Inc.,
     Aimnet Corporation, Clark Internet Services, Inc., ATMnet Corporation and
     Global Internet Network Services, Inc. at the dates indicated, and the
     statement of operations, stockholders' deficit/equity and cash flows of
     each of such persons and, where applicable such persons' consolidated
     subsidiaries for the periods have been prepared in conformity with United
     States generally accepted accounting principles ("GAAP") applied on a
     consistent basis throughout the periods involved. The selected financial
     data and the summary financial information included in the Final Memorandum
     present fairly the information shown therein and have been compiled on a
     basis consistent with that of the financial statements of the Company and
     its consolidated subsidaries included in the Final Memorandum. KPMG Peat
     Marwick LLP, which has examined such financial statements as set forth in
     its report included in the Final Memorandum, is an independent public
     accounting firm with respect to each of such persons and, where applicable
     such persons Subsidiaries within the meaning of Regulation S-X under the
     Securities Act. Except as disclosed in the Final Memorandum, the pro forma
     financial information relating to the Company and its Subsidiaries and the
     related notes thereto included in the Final Memorandum present fairly the
     information shown therein, have been prepared in all material respects in
     accordance with the Commission's rules and guidelines with respect to pro
     forma financial adjustments and have been properly computed 



                                      -7-
<PAGE>   8

     on the bases described therein, and the assumptions used in the preparation
     thereof are reasonable and the adjustments used therein are appropriate to
     give effect to the transactions and circumstances referred to therein.

         (n) Since the respective dates as of which information is given in the
     Final Memorandum, except as otherwise specifically stated therein, there
     has been no (A) material adverse change in the business, condition
     (financial or otherwise), results of operations, business affairs or
     business prospects of the Company and the Subsidiaries taken as a whole,
     whether or not arising in the ordinary course of business (a "Material
     Adverse Change"), (B) transaction entered into by any of the Company or the
     Subsidiaries, other than in the ordinary course of business, that is
     material to the Company and the Subsidiaries taken as a whole or (C)
     dividend or distribution of any kind declared, paid or made by the Company
     on its capital stock.

         (o) The Company has the authorized, issued and outstanding
     capitalization set forth in the Final Memorandum under the caption
     "Description of Capital Stock"; all of the outstanding capital stock of the
     Company has been duly authorized and validly issued, is fully paid and
     nonassessable and was not issued in violation of any preemptive or similar
     rights (whether provided contractually or pursuant to any Organizational
     Document). Except as set forth in the Final Memorandum under the caption
     "Business-- Verio Group Network," the Company does not own, directly or
     indirectly, any material amount of shares, or any other material amount of
     equity or long-term debt securities or have any material equity interest in
     any firm, partnership, joint venture or other entity. Except as set forth
     in the Final Memorandum, no holder of any securities of the Company is
     entitled to have such securities (other than the Securities, the Exchange
     Notes and the Private Exchange Notes, if any) registered under any
     registration statement contemplated by the Registration Agreement. All of
     the outstanding capital stock of each of the Subsidiaries has been duly
     authorized and validly issued, is fully paid and nonassessable and was not
     issued in violation of any preemptive or similar rights (whether provided
     contractually or pursuant to any Organizational Document).

         (p) None of the Company nor the Subsidiaries is (A) in violation of its
     respective Organizational Documents, (B) in default (or, with notice or
     lapse of time or 


                                      -8-
<PAGE>   9

     both, would be in default) in the performance or observance of any
     obligation, agreement, covenant or condition contained in any Contract or
     (C) in violation of any law, statute, judgment, decree, order, rule or
     regulation of any domestic or foreign court with jurisdiction over the
     Company or the Subsidiaries or any of their respective assets or
     properties, or other governmental or regulatory authority, agency or other
     body, other than, in the case of clause (B) or (C), such defaults or
     violations which could not, individually or in the aggregate, reasonably be
     expected to have or result in a Material Adverse Effect; and any real
     property and buildings held under lease by the Company or the Subsidiaries
     are held by the Company or such Subsidiary, as the case may be, under
     valid, subsisting and enforceable leases with such exceptions which could
     not, individually or in the aggregate, reasonably be expected to have or
     result in a Material Adverse Effect.

         (q) Except as set forth in the Final Memorandum, each of the Company
     and the Subsidiaries owns or possesses, or can acquire on reasonable terms,
     adequate patents, patent rights, licenses, trademarks, service marks, trade
     names, copyrights and know-how (including trade secrets and other
     proprietary or confidential information, systems or procedures)
     (collectively, "intellectual property") necessary to conduct the business
     now or proposed to be operated by it as described in the Final Memorandum,
     except where the failure to own, possess or have the ability to acquire any
     such intellectual property could not, individually or in the aggregate, be
     reasonably expected to have a Material Adverse Effect; and none of the
     Company nor the Subsidiaries has received any notice of infringement of or
     conflict with (nor knows of any such infringement of or conflict with)
     asserted rights of others with respect to any of such intellectual
     property.

         (r) Each of the Company and the Subsidiaries has obtained all material
     consents, approvals, orders, certificates, licenses, permits, franchises
     and other authorizations (collectively, the "Licenses") of and from, and
     has made all declarations and filings with, all governmental and regulatory
     authorities, all self-regulatory organizations and all courts and other
     tribunals necessary to own, lease, license and use its properties and
     assets and to conduct its businesses in the manner described in the Final
     Memorandum. None of the Company or the Subsidiaries has received any notice
     of proceedings relating to the revocation or modification of, or denial of
     any application 



                                      -9-
<PAGE>   10

     for, any License which, if the subject of any unfavorable decision, ruling
     or finding, could, singly or in the aggregate, reasonably be expected to
     have or result in a Material Adverse Effect; and no event has occurred
     which allows, or after notice or lapse of time, or both, would allow,
     revocation or termination thereof or result in any other material
     impairment of the rights of the holder of any such License, except where
     such revocation or termination could not, singly or in the aggregate,
     reasonably be expected to have or result in a Material Adverse Effect; and
     the Licenses referred to above place no restrictions on the Company or any
     of the Subsidiaries that are not described in the Final Memorandum, except
     where such restrictions could not, singly or in the aggregate, reasonably
     be expected to have or result in a Material Adverse Effect.

         (s) There is no legal action, suit, proceeding, inquiry or
     investigation before or by any court or governmental body or agency,
     domestic or foreign, now pending or, to the best knowledge of the Company,
     threatened against the Company or any of the Subsidiaries or any of their
     respective properties which would be required to be disclosed in a
     registration statement filed under the Securities Act.

         (t) Each of the Company and the Subsidiaries has filed all necessary
     federal, state and foreign income and franchise tax returns, and has paid
     all taxes shown as due thereon; and no tax deficiency has been asserted
     against any of the Company or the Subsidiaries.

         (u) Except as described in the Final Memorandum, including the
     financial statements and notes thereto included therein, each of the
     Company and the Subsidiaries has good and marketable title to all real and
     personal property described in the Final Memorandum as being owned by it
     and good and marketable title to a leasehold estate in the real and
     personal property described in the Final Memorandum as being leased by it,
     free and clear of all liens, charges, encumbrances or restrictions, except
     to the extent the failure to have such title or the existence of such
     liens, charges, encumbrances or restrictions could not, individually or in
     the aggregate, reasonably be expected to have or result in a Material
     Adverse Effect.

         (v) None of the Company or any of the Subsidiaries is an "investment
     company" or a company "controlled by" an 


                                      -10-
<PAGE>   11

     "investment company" as such terms are defined in the Investment Company
     Act of 1940, as amended, and the rules and regulations thereunder.

         (w) None of the Company nor any of the Subsidiaries nor any of their
     respective directors, officers or controlling persons has taken, directly
     or indirectly, any action designed, or which might reasonably be expected,
     to cause or result, under the Securities Act or otherwise, in, or which has
     constituted, stabilization or manipulation of the price of any security of
     the Company to facilitate the sale or resale of the Securities, the
     Exchange Notes or the Private Exchange Notes.

         (x) No strike, labor problem, dispute, slowdown, work stoppage or
     disturbance with the employees of the Company or any of the Subsidiaries
     exists or, to the best knowledge of the Company, is threatened which could,
     individually or in the aggregate, reasonably be expected to have or result
     in a Material Adverse Effect.

         (y) The Company has insurance in such amounts and covering such risks
     and liabilities as are in accordance with normal industry practice.

         (z) The statistical and market-related data included in the Final
     Memorandum are based on or derived from independent sources which the
     Company believes to be reliable and accurate in all material respects or
     represent the Company's good faith estimates that are made on the basis of
     data derived from such sources.

         (aa) The Company is, and immediately after the Closing Date will be,
     Solvent. As used herein, the term "Solvent" means, with respect to the
     Company on a particular date, that on such date (A) the fair market value
     of the assets of the Company exceeds its respective liabilities (including
     without limitation, stated liabilities and identified contingent
     liabilities), (B) the present fair salable value of the assets of the
     Company will exceed its respective probable liabilities on its debts
     (including without limitation, stated liabilities and identified contingent
     liabilities), (C) the fair market value of the Company's total assets
     exceeds its total liabilities, including identified contingent liabilities,
     by an amount at least equal to the total par value of its common stock both
     immediately prior to and after the Offering, (D) the Company is and will be
     able to pay its debts (including 



                                      -11-
<PAGE>   12

     without limitation, stated liabilities and identified contingent
     liabilities) as such debts mature and (E) the Company will not have
     unreasonably small capital with which to conduct its present and
     anticipated business.

         (bb) Except as described in the Final Memorandum or as would not,
     individually or in the aggregate, reasonably be expected to have a Material
     Adverse Effect (A) to the Company's knowledge, each of the Company and the
     Subsidiaries is in compliance with and not subject to any known liability
     under applicable Environmental Laws (as defined below), (B) to the
     Company's knowledge, each of the Company and the Subsidiaries (i) has made
     all filings and provided all notices required under any applicable
     Environmental Law, and (ii) has, and is in compliance with, all Permits
     required under any applicable Environmental Laws, and (iii) each of them is
     in full force and effect, (C) to the Company's knowledge, there is no
     civil, criminal or administrative action, or, investigation, notice or
     demand letter or request for information pending or threatened against the
     Company or any of the Subsidiaries under any Environmental Law, and (D) to
     the Company's knowledge, no lien, charge, encumbrance or restriction has
     been recorded under any Environmental Law with respect to any assets,
     facility or property owned, operated, leased or controlled by the Company
     or any Subsidiary.

         For purposes of this Agreement, "Environmental Laws" means the common
     law and all applicable federal, state and local laws or regulations
     relating to the protection of the environment, including, without
     limitation, laws relating to emissions, discharges, releases or threatened
     releases of "hazardous substances," as defined in the Comprehensive
     Environmental Response, Compensation and Liability Act of 1980, as amended.

         (cc) Except as described in the Final Memorandum, none of the Company
     nor any of the Subsidiaries has incurred any liability for any prohibited
     transaction or funding deficiency or any complete or partial withdrawal
     liability with respect to any pension, profit sharing or other plan which
     is subject to the Employee Retirement Income Security Act of 1974, as
     amended ("ERISA"), to which the Company or the Subsidiaries makes or ever
     has made a contribution and in which any employee of the Company or any
     such Subsidiary is or has ever been a participant, which, individually in
     the aggregate, could reasonably be expected to have or result in a Material
     Adverse Effect. 



                                      -12-
<PAGE>   13

     With respect to such plans, each of the Company and the Subsidiaries is in
     compliance in all respects with all applicable provisions of ERISA, except
     where the failure to so comply could not, individually or in the aggregate,
     reasonably be expected to have or a result in a Material Adverse Effect.

         (dd) Each of the Company and the Subsidiaries maintains a system of
     internal accounting controls sufficient to provide reasonable assurance
     that (i) transactions are executed in accordance with management's general
     or specific authorizations; (ii) transactions are recorded as necessary to
     permit preparation of financial statements in conformity with generally
     accepted accounting principles and to maintain asset accountability; (iii)
     access to assets is permitted only in accordance with management's general
     or specific authorization; and (iv) the recorded accountability for assets
     is compared with the existing assets at reasonable intervals and
     appropriate action is taken with respect to any differences.

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

         (ff) Any certificate signed by any officer of the Company and delivered
     to the Initial Purchasers or to Cahill Gordon & Reindel, counsel for the
     Initial Purchasers ("Counsel for the Initial Purchasers") pursuant to the
     terms of this Agreement shall be deemed a representation and warranty by
     the Company to the Initial Purchasers as to the matters covered thereby.

         2. Purchase and Sale of the Securities. Subject to the terms and
conditions and in reliance upon the representations and warranties herein set

                                      -13-
<PAGE>   14

and payment for the Securities being herein called the "Closing Date"). Delivery

accounts of the Initial Purchasers against payment by the Initial Purchasers of
the purchase price thereof to or upon the order of the Company by wire transfer

the Company and the Initial Purchasers. Certificates for the Securities shall be
registered in such names and in such denominations as the Initial Purchasers may
request not less than two full business days in advance of the Closing Date.

         The Company agrees to have the Securities available for inspection,
checking and packaging by the Initial Purchasers in New York, New York, not
later than 10:00 AM on the business day prior to the Closing Date.

         4. Offering of Securities. Each Initial Purchaser, severally and not
jointly, represents and warrants to and agrees with the Company that:

         (a) It has not offered or sold, and will not offer or sell, any
     Securities except (i) to those it reasonably believes to be QIBs and that,
     in connection with each such sale, it has taken or will take reasonable
     steps to ensure that the purchaser of such Securities is aware that such

     restrictions set forth in Exhibit A hereto.

         (b) Neither it nor any person acting on its behalf has made or will
     make offers or sales of the Securities in the United States by means of any
     form of general solicitation or general advertising within the meaning of
     Regulation D in the United States.

         5. Agreements of the Company. The Company agrees with each Initial
Purchaser that:

         (a) The Company will furnish to each Initial Purchaser and to Counsel

     in paragraph (c) below, 



                                      -14-
<PAGE>   15

     as many copies of the Preliminary Memorandum and the Final Memorandum and
     any amendments and supplements thereto as each Initial Purchaser and
     Counsel for the Initial Purchasers may reasonably request.

         (b) The Company will not at any time make any amendment or supplement
     to the Preliminary Memorandum or the Final Memorandum without the prior
     written consent of the Initial Purchasers.

         (c) The Company will immediately notify each Initial Purchaser and
     confirm such notice in writing of (x) any filing made by the Company
     relating to the offering of the Securities with any securities exchange or
     any other regulatory body in the United States or any other jurisdiction
     and (y) prior to the completion of the placement of the Securities by the
     Initial Purchasers as evidenced by a notice in writing from the Initial
     Purchasers to the Company, any material changes in or affecting the
     earnings, business affairs or business prospects of the Company and its
     Subsidiaries that (i) make any statement in the Final Memorandum false or
     misleading in any material respect or (ii) are not disclosed in the Final
     Memorandum. In such event or if at any time prior to completion of the
     distribution of the Securities by the Initial Purchasers to purchasers who
     are not its affiliates (as determined by the Initial Purchasers) any other
     event shall occur or condition shall exist as a result of which it is
     necessary, in the opinion of the Initial Purchasers or Counsel for the
     Initial Purchasers, to amend or supplement the Final Memorandum in order
     that the Final Memorandum, as then amended or supplemented, will not
     include an untrue statement of a material fact or omit to state a material
     fact necessary in order to make the statements therein, in the light of the
     circumstances existing at the time it is delivered to a purchaser, not
     misleading or if in the opinion of the Initial Purchasers or Counsel for
     the Initial Purchasers, such amendment or supplement is necessary to comply
     with applicable law, the Company will, subject to paragraph (b) of this
     Section 5, promptly prepare, at its own expense, such amendment or
     supplement as may be necessary to correct such untrue statement or omission
     or to effect such compliance (in form and substance agreed upon by the
     Initial Purchasers and Counsel for the Initial Purchasers), so that as so
     amended or supplemented, the statements in the Final Memorandum will not
     include an untrue statement of a material fact or omit to state a material
     fact necessary in order to make the statements therein, in the light



                                      -15-
<PAGE>   16

     of the circumstances existing at the time it is delivered to a purchaser,
     not misleading or so that such Final Memorandum as so amended or
     supplemented will comply with applicable law, as the case may be, and
     furnish to the Initial Purchasers such number of copies of such amendment
     or supplement as the Initial Purchasers may reasonably request. The Company
     agrees to notify the Initial Purchasers in writing to suspend use of the
     Final Memorandum as promptly as practicable after the occurrence of an
     event specified in this paragraph (c), and the Initial Purchasers hereby
     agree upon receipt of such notice from the Company to suspend use of the
     Final Memorandum until the Company has amended or supplemented the Final

         the Exchange Notes, the Indenture, the Registration Agreement, the
         Company's authorized and outstanding capital stock and the Company's
         13-1/2% Senior Notes due 2004, provide a fair summary of such

         and the Registration Agreement, the Enforceability Limitations,
         including the waiver contained in Section 5.15 of the Indenture, and

             (11) Each of the Securities, when executed and authenticated in
         accordance with the provisions of the Indenture and delivered and paid
         for in accordance with the terms of this Agreement, and the Exchange
         Notes and the Private Exchange Notes, if any, when executed,

         obligations of the Company, enforceable in accordance with its terms
         except as the enforceability thereof may be limited by the
         Enforceability Limitations;

             (12) To the knowledge of such counsel, other than as described in
         the Final Memorandum, no legal, regulatory or governmental proceedings
         are pending to which the Company is a party or to which the property or
         assets of the Company are subject which, individually or in the
         aggregate, could reasonably be expected to have a Material Adverse
         Effect or which, individually or in the aggregate, could have a
         material adverse effect on the power or ability of the Company to
         perform its obligations under the Transaction Documents or to
         consummate the transactions contemplated thereby or by the Offering
         Memorandum and to the knowledge of such counsel, no such material
         proceedings have been threatened against the Company or with respect to
         any of its respective assets or properties;

             (13) Assuming (a) the accuracy of, and compliance with, the
         representations, warranties and covenants of the Company in subsections
         1(c) and 1(d) of the Purchase Agreement, (b) the accuracy of, and
         compliance with, the representations, warranties and covenants of the

         resell the Securities of a copy of the Final Memorandum prior to such
         sale, it is not necessary in connection with the offer, sale and
         delivery of the Securities or in connection with the initial resale of
         such Securities in the manner contemplated by the Purchase Agreement
         and the Offering Memorandum to register the Securities 


                                      -22-

         under the Securities Act or to qualify the Indenture under the Trust
         Indenture Act, it being understood that no opinion is expressed as to
         any subsequent resale of any Securities;

             (14) When the Securities are issued and delivered pursuant to this
         Agreement, such Securities will not be of the same class (within the
         meaning of Rule 144A) as securities of the Company which are listed on
         a national securities exchange registered under Section 6 of the
         Exchange Act or quoted in a U.S. automated inter-dealer quotation
         system; and

             (15) Neither the consummation of the transactions contemplated
         hereby nor the sale, issuance, execution or delivery of the Securities
         will violate Regulation G, T, U or X of the Board of Governors of the
         Federal Reserve System.

         In addition, such counsel shall state that such counsel has
     participated in conferences with representatives of the Initial Purchasers,
     officers and other representatives of the Company and representatives of
     the independent certified accountants of the Company, at which conferences
     the contents of the Preliminary Memorandum and Final Memorandum and the
     business and affairs of the Company and the Subsidiaries were discussed,
     and although such counsel has not independently verified and does not pass
     upon or assume any responsibility for the accuracy, completeness or
     fairness of the statements contained in the Final Memorandum (except and
     only to the extent set forth in subclauses (8) and (9) above), on the basis
     of the foregoing (relying as to materiality to the extent such counsel
     deemed appropriate upon the representations and opinions of officers and
     other representatives of the Company), no facts have come to the attention
     of such counsel which lead such counsel to believe that the Final
     Memorandum at the date thereof or as of the Closing Date, contained or
     contains an untrue statement of a material fact or omitted or omits to
     state a material fact necessary to make the statements therein, in the
     light of the circumstances under which they were made, not misleading (it
     being understood that such counsel need not express any comment with
     respect to the financial statements, including the notes thereto and
     supporting schedules, or any other financial or statistical data set forth
     or referred to in the Final Memorandum).

     any supplements thereto at or prior to the Closing Date.

         Adverse Effect or which, individually or in the aggregate, could have a
         material adverse effect on the power or ability of the Company to
         perform its obligations under the Transaction Documents or to
         consummate the transactions contemplated thereby or by the Final
         Memorandum and to the knowledge of such counsel, no such material

         respective Organizational Documents; to the knowledge of such counsel,
         no default by the Company or any of the Subsidiaries exists in the due

         covenant or condition contained in any Material Contract which could
         reasonably be expected to have a Material Adverse Effect; and to the
         knowledge of such counsel, none of the Company nor the Subsidiaries is
         in breach or violation of any

         any governmental or regulatory agency or other body having jurisdiction
         over the Company or any of the Subsidiaries or any of their respective

         In rendering such opinions, such counsel (A) need not express any

     have come to the attention of such counsel which lead such counsel to
     believe that the Final Memorandum, at the date thereof or as of the Closing
     Date, contained or contains an untrue statement of a material fact or
     omitted to state a material fact necessary to make the statements therein,
     in the light of the circumstances under which they were made, not
     misleading (it being understood that such counsel need express no comment
     with respect to the financial statements, including the notes thereto, or
     any other financial or statistical data set forth or referred to in the
     Final Memorandum).

         (c) The following conditions contained in clauses (i) and (ii) of this
     subsection (c) shall have been satisfied 


                                      -26-
<PAGE>   27

     at and as of the Closing Date, and the Company shall have furnished to the
     Initial Purchasers a certificate of the Company, signed by the Chairman of
     the Board or the President and the principal financial or accounting
     officer of the Company, dated the Closing Date, to the effect that the
     signers of such certificate have carefully examined the Final Memorandum,
     any amendment or supplement to the Final Memorandum and this Agreement and
     that:

             (i) the representations and warranties of the Company in this
         Agreement are true and correct in all material respects on and as of
         the Closing Date with the same effect as if made on the Closing Date,
         and the Company has complied with all the agreements and satisfied all
         the conditions on its part to be performed or satisfied hereunder in
         all material respects at or prior to the Closing Date; and

             (ii) since the date of the most recent financial statements
         included in the Final Memorandum (exclusive of any amendment or
         supplement thereto), there has been no Material Adverse Change, whether
         or not in the ordinary course of business. As used in this
         subparagraph, the term "Final Memorandum" means the Final Memorandum in
         the form first used to confirm sales of the Securities.

         (d) At the Execution Time and at the Closing Date, KPMG Peat Marwick
     LLP shall have furnished to the Initial Purchasers a letter or letters,
     dated respectively as of the Execution Time and as of the Closing Date, in
     form and substance satisfactory to the Initial Purchasers, confirming that
     they are independent accountants within the meaning of the Securities Act
     and the Exchange Act and the applicable published rules and regulations
     thereunder and Rule 101 of the Code of Professional Conduct of the American
     Institute of Certified Public Accountants (the "AICPA") and containing
     statements and information of the type ordinarily included in accountants'
     "comfort letters" to Initial Purchasers with respect to financial
     statements and certain financial information contained in the Final
     Memorandum, in form and substance satisfactory to Counsel for the Initial
     Purchasers.

         KPMG Peat Marwick LLP shall have also furnished to the Initial
     Purchasers a letter stating that the Company's system of internal
     accounting controls taken as a whole is sufficient to meet the broad
     objectives of internal accounting 


                                      -27-
<PAGE>   28

     control insofar as those objective pertain to the prevention or detection
     of errors or irregularities in amounts that would be material in relation
     to the financial statements of the Company and its subsidiaries.

         All references in this Section 6(d) to the Final Memorandum shall be
     deemed to include any amendment or supplement thereto at the date of the
     letter.

         (e) Subsequent to the Execution Time or, if earlier, the dates as of
     which information is given in the Final Memorandum, there shall not have
     been (i) any change or decrease specified in the letter or letters referred
     to in paragraph (d) of this Section 6 or (ii) any change, or any
     development involving a prospective change, in or affecting the business or
     properties of the Company and its subsidiaries the effect of which, in any
     case referred to in clause (i) or (ii) above, is, in the judgment of the
     Initial Purchasers, so material and adverse as to make it impractical or
     inadvisable to market the Securities as contemplated by the Final
     Memorandum.

         (f) On or prior to the Closing Date, the Company shall have furnished
     to the Initial Purchasers such further information, certificates and
     documents as the Initial Purchasers may reasonably request.

         (g) The Company and the Trustee shall have entered into the Indenture.

         (h) The Company and the Initial Purchasers shall have entered into the
     Registration Agreement.

         (i) The Company shall have repurchased from WorldCom, Inc. and
     cancelled $50,000,000 aggregate principal amount of the Company's 13-1/2%
     Senior Notes due 2004.

         If any of the conditions specified in this Section 6 shall not have
been fulfilled when and as provided in this Agreement, or if any of the opinions
and certificates mentioned above or elsewhere in this Agreement shall not be in
all material respects reasonably satisfactory in form and substance to the
Initial Purchasers and Counsel for the Initial Purchasers, this Agreement and
all obligations of the Initial Purchasers hereunder may be canceled at, or at
any time prior to, the Closing Date by the Initial Purchasers. Notice of such
cancellation shall be given to the Company in writing or by telephone or
telegraph confirmed in writing.



                                      -28-
<PAGE>   29

         The documents required to be delivered by this Section 6 will be
delivered at the office of Counsel for the Initial Purchasers, at 80 Pine
Street, New York, New York, on the Closing Date.

         7. Reimbursement of Expenses. (a) Whether or not any sale of the
Securities is consummated, the Company agrees to pay and bear all costs and
expenses incident to the performance of all of its obligations under this
Agreement, including (i) the preparation and printing of the Preliminary
Memorandum, the Final Memorandum and any amendments or supplements thereto and
the cost of furnishing copies thereof to the Initial Purchasers, (ii) the
preparation, issuance, printing and distribution of the Securities, the Exchange
Notes, the Private Exchange Notes, if any, and any survey of state securities or
"blue sky" laws or legal investment memoranda, (iii) the delivery to the Initial
Purchasers of the Securities, the Exchange Notes or the Private Exchange Notes,
(iv) the fees and disbursements of the Company's counsel and accountants, (v)
the qualification of the Securities under the applicable state securities or
"blue sky" laws in accordance with the provisions of Section 5(i) hereof and any
filing for review of the offering with the NASD, if required, including filing
fees and reasonable fees and disbursements of counsel to the Initial Purchasers
in connection therewith and in connection with the preparation of any survey of
state securities or "blue sky" laws or legal investment memoranda, (vi) any fees
charged by rating agencies for rating the Securities, the Exchange Notes and the
Private Exchange Notes, if any, (vii) the fees and expenses of the Trustee,
including the fees and disbursements of counsel for the Trustee, (viii) all
expenses (including travel expenses) of the Company and the Initial Purchasers
in connection with any meetings with prospective investors in the Securities and
(ix) all expenses and listing fees in connection with the application for
designation of the Securities as PORTAL securities and to permit the Securities,
the Exchange Notes and the Private Exchange Notes, as applicable, to be eligible
to clearance through The Depository Trust Company.

         (b) If the sale of the Securities provided for herein is not
consummated because any condition to the obligations of the Initial Purchasers
set forth in Section 6 hereof is not satisfied, because of any termination
pursuant to Section 10 hereof or because of any refusal, inability or failure on
the part of the Company to perform any agreement herein or comply with any
provision hereof other than by reason of a default by any of the Initial
Purchasers in payment for the Securities on the Closing Date, the Company will
reimburse the Initial 



                                      -29-
<PAGE>   30

Purchasers severally upon demand for all reasonable out-of-pocket expenses
(including reasonable fees and disbursements of counsel) that shall have been
incurred by them in connection with the proposed purchase and sale of the
Securities.

         8. Indemnification and Contribution. (a) The Company agrees to
indemnify and hold harmless each Initial Purchaser, the directors, officers,
employees and agents of each Initial Purchaser and each person who controls any
Initial Purchaser within the meaning of either the Securities Act or the
Exchange Act against any and all losses, claims, damages or liabilities, joint
or several, to which they or any of them may become subject under the Securities
Act, the Exchange Act or other Federal or state statutory law or regulation, at
common law or otherwise, insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of a material fact contained in the
Preliminary Memorandum or the Final Memorandum or in any amendment thereof or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, and agree to reimburse each such
indemnified party, as incurred, for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that the Company will not
be liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon any such untrue statement or alleged
untrue statement or omission or alleged omission made in the Preliminary
Memorandum or the Final Memorandum, or in any amendment thereof or supplement
thereto, in reliance upon and in conformity with written information furnished
to the Company by or on behalf of any Initial Purchasers specifically for
inclusion therein. This indemnity agreement will be in addition to any liability
which the Company may otherwise have.

         The foregoing indemnity with respect to any untrue statement contained
in or any omission from the Preliminary Memorandum shall not inure to the
benefit of any Initial Purchaser (or any affiliate or person who controls such
Initial Purchaser within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act) from whom the person asserting such loss,
liability, claim, damage or expense purchased any of the Securities that are the
subject thereof if such person was not sent or given a copy of the Final
Memorandum (or any amendment or supplement thereto), if the Company 



                                      -30-
<PAGE>   31

shall have previously furnished copies thereof to the Initial Purchasers in
accordance with this Agreement, at or prior to the written confirmation of the
sale of such Securities to such person and the untrue statement contained in or
the omission from the Preliminary Memorandum was corrected in the Final
Memorandum (or any amendment or supplement thereto).

         (b) Each Initial Purchaser severally and not jointly agrees to
indemnify and hold harmless the Company, its directors, officers and each person
who controls the Company within the meaning of either the Securities Act or the
Exchange Act to the same extent as the foregoing indemnity from the Company to
each Initial Purchaser, but only with reference to written information relating
to such Initial Purchaser furnished to the Company by or on behalf of such
Initial Purchaser specifically for inclusion in the Preliminary Memorandum or
the Final Memorandum (or in any amendment or supplement thereto). This indemnity
agreement will be in addition to any liability which any Initial Purchaser may
otherwise have. The Company acknowledges that the statements set forth in the
last paragraph of the cover page and in the table, fifth paragraph and tenth
paragraph under the heading "Plan of Distribution" in the Preliminary Memorandum
and the Final Memorandum constitute the only information furnished in writing by
or on behalf of the Initial Purchasers for inclusion in the Preliminary
Memorandum or the Final Memorandum (or in any amendment or supplement thereto).

         (c) Promptly after receipt by an indemnified party under this Section 8
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party in writing of the commencement thereof;
but the failure so to notify the indemnifying party (i) will not relieve it from
liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such failure results in the forfeiture by the
indemnifying party of substantial rights and defenses and (ii) will not, in any
event, relieve the indemnifying party from any obligations to any indemnified
party other than the indemnification obligation provided in paragraph (a) or (b)
above. The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent the
indemnified party in any action for which indemnification is sought (in which
case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties
except as set forth below); provided, 



                                      -31-
<PAGE>   32

however, that such counsel shall be satisfactory to the indemnified party.
Notwithstanding the indemnifying party's election to appoint counsel to
represent the indemnified party in an action, the indemnified party shall have
the right to employ separate counsel (including local counsel), and the
indemnifying party shall bear the reasonable fees, costs and expenses of such
separate counsel if (i) the use of counsel chosen by the indemnifying party to
represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense
of the indemnifying party. An indemnifying party will not, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any pending or threatened claim,
action, suit or proceeding in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified parties are actual or
potential parties to such claim or action) unless such settlement, compromise or
consent includes an unconditional release of each indemnified party from all
liability arising out of such claim, action, suit or proceeding.

         (d) In the event that the indemnity provided in paragraph (a) or (b) of
this Section 8 is unavailable to or insufficient to hold harmless an indemnified
party for any reason, the Company on the one hand and the Initial Purchasers on
the other hand agree to contribute to the aggregate losses, claims, damages and
liabilities (including legal or other expenses reasonably incurred in connection
with investigating or defending same) (collectively, "Losses") to which the
Company or one or more of the Initial Purchasers, as applicable, may be subject
in such proportion as is appropriate to reflect the relative benefits received
by the Company or the Initial Purchasers from the offering of the Securities;
provided, however, that in no case shall any Initial Purchaser be responsible
for any amount in excess of the purchase discount or commission applicable to
the Securities purchased by such Initial Purchaser hereunder. If the allocation
provided by the immediately preceding sentence is unavailable for any reason,
the Company and 



                                      -32-
<PAGE>   33

the Initial Purchasers shall contribute in such proportion as is appropriate to
reflect not only such relative benefits but also the relative fault of the
Company or the Initial Purchasers, as applicable, in connection with the
statements or omissions which resulted in such Losses as well as any other
relevant equitable considerations. Benefits received by the Company shall be
deemed to be equal to the total net proceeds from the offering received by each
of them, respectively, (before deducting expenses), and benefits received by the
Initial Purchasers shall be deemed to be equal to the total purchase discounts
and commissions received by the Initial Purchasers from the Company in
connection with the purchase of the Securities hereunder. Relative fault shall
be determined by reference to whether any alleged untrue statement or omission
relates to information provided by the Company or the Initial Purchasers. The
Company and the Initial Purchasers agree that it would not be just and equitable
if contribution were determined by pro rata allocation or any other method of
allocation which does not take account of the equitable considerations referred
to above. Notwithstanding the provisions of this paragraph (d), no person guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this Section 8 each
person who controls an Initial Purchaser within the meaning of either the
Securities Act or the Exchange Act and each director, officer, employee and
agent of an Initial Purchaser shall have the same rights to contribution as such
Initial Purchaser, and each person who controls the Company within the meaning
of either the Securities Act or the Exchange Act and each officer and director
of the Company shall have the same rights to contribution as the Company subject
in each case to the applicable terms and conditions of this paragraph (d).

         9. Default by an Initial Purchaser. If any one or more Initial
Purchasers shall fail to purchase and pay for any of the Securities agreed to be
purchased by such Initial Purchaser hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Initial Purchasers shall be obligated severally to take
up and pay for (in the respective proportions which the principal amount of
Securities set forth opposite their names in Schedule I hereto bears to the
aggregate principal amount of securities set forth opposite the names of all the
remaining Initial Purchasers) the Securities which the defaulting Initial
Purchaser or Initial Purchasers agreed but failed to purchase; provided,
however, that in the event that the aggregate principal amount of Securities
which the defaulting 


                                      -33-
<PAGE>   34

Initial Purchaser or Initial Purchasers agreed but failed to purchase shall
exceed 10% of the aggregate principal amount of Securities set forth in Schedule
I hereto, the remaining Initial Purchasers shall have the right to purchase all,
but shall not be under any obligation to purchase any, of the Securities, and if
such non-defaulting Initial Purchasers do not purchase all the Securities, this
Agreement will terminate without liability to any non-defaulting Initial
Purchaser or Company. In the event of a default by any Initial Purchaser as set
forth in this Section 9 the Closing Date shall be postponed for such period, not
exceeding seven days, as the Initial Purchasers shall determine in order that
the required changes in the Final Memorandum or in any other documents or
arrangements may be effected. Nothing contained in this Agreement shall relieve
any defaulting Initial Purchaser of its liability, if any, to the Company or any
non-defaulting Initial Purchaser for damages occasioned by its default
hereunder.

         10. Termination. This Agreement shall be subject to termination in the
absolute discretion of the Initial Purchasers, by notice given to the Company
prior to delivery of and payment for the Securities, if prior to such time (i)
trading in any of the Company's securities shall have been suspended by the
Commission or trading in securities generally on the New York Stock Exchange or
the NASDAQ National Market shall have been suspended or limited or minimum
prices shall have been established on either of such exchanges, (ii) a banking
moratorium shall have been declared either by Federal or New York State
authorities or (iii) there shall have occurred any outbreak or escalation of
hostilities, declaration by the United States of a national emergency or war or
other calamity or crisis the effect of which on financial markets is such as to
make it, in the judgment of the Initial Purchasers, impracticable or inadvisable
to proceed with the offering or delivery of the Securities as contemplated by
the Final Memorandum.

         11. Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of the
Company or its officers, and of the Initial Purchasers set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation made by or on behalf of the Initial Purchasers or the Company
or any of the officers, directors or controlling persons referred to in Section
8 hereof, and will survive delivery of and payment for the Securities. The
provisions of Sections 7 and 8 hereof shall survive the termination or
cancellation of this Agreement.

binding upon the parties hereto and their respective successors and the officers
and directors and controlling persons referred to in Section 8 hereof, and,
except as expressly set forth in Section 5(f) hereof, no other person will have
any right or obligation hereunder.

         14. Applicable Law. This Agreement will be governed by and construed in
accordance with the laws of the State of New York.

         15. Business Day. For purposes of this Agreement, "business day" means
each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which
banking institutions in the City of New York, New York are authorized or
obligated by law, executive order or regulation to close.

         16. Counterparts. This Agreement may be executed in one or more
counterparts, each of which will be deemed to be an original, but all such
counterparts will together constitute one and the same instrument.

         (1) (a) The Securities have not been and will not be registered under
the Securities Act and may not be offered or sold within the United States or
to, or for the account or benefit of, U.S. persons except in accordance with
Regulation S under the Securities Act or pursuant to an exemption from the

(ii) of the Agreement to which this is an exhibit, it has offered and sold the
Securities, and will offer and sell the Securities, (i) as part of their
distribution at any time and (ii) otherwise until 40 days after the later of the
commencement of the offering and the Closing Date, only in accordance with Rule
903 of Regulation S under the Securities Act. Accordingly, each Initial
Purchaser represents and agrees that neither it, nor any of its affiliates nor
any person acting on its or their behalf has engaged or will engage in any
directed selling efforts with respect to the Securities, and that it and they
have complied and will comply with the offering restrictions requirement of
Regulation S. Each Initial Purchaser agrees that, at or prior to the
confirmation of sale of Securities (other than a sale of Securities pursuant to
Section 4(a)(i) or (ii) of the Agreement to which this is an exhibit), it shall
have sent to each distributor, dealer or person receiving a selling concession,
fee or other remuneration that purchases Securities from it during the
restricted period a confirmation or notice to substantially the following
effect:

         "The Securities covered hereby have not been registered under the U.S.
     Securities Act of 1933 (the "Securities Act") and may not be offered or
     sold within the United States or to, or for the account or benefit of, U.S.
     persons (i) as part of their distribution at any time or (ii) otherwise
     until 40 days after the later of the commencement of the offering and
     [specify closing date of the offering], except in either case in accordance
     with Regulation S or Rule 144A under the Securities Act. Terms used above
     have the meanings given to them by Regulation S."

         (b) Each Initial Purchaser also represents and agrees that it has not
entered and will not enter into any contractual arrangement with any distributor
with respect to the distribution of the Securities, except with its affiliates
or with the prior written consent of the Company.

         (c) Terms used in this section have the meanings given to them by
Regulation S.

         (2) Each Initial Purchaser represents and agrees that (i) it has not
offered or sold and will not offer or sell, in the United Kingdom, by means of
any document, any Securities other than to persons whose ordinary business it is
to buy or sell shares or debentures, whether as principal or as agent (except in
circumstances which do not constitute an offer to the public within the meaning
of the Companies Act 1985 of Great Britain), (ii) it has complied and will
comply with all applicable provisions of the Financial Services Act 1986 of the
United Kingdom with respect to anything done by it in relation to the Securities
in, from or otherwise involving the United Kingdom, and (iii) it has only issued
or passed on and will only issue or pass on in the United Kingdom any document
received by it in connection with the issue of the Securities to a person who is
of a kind described in Article 9(3) of the Financial Services Act 1986
(Investment Advertisements) (Exemptions) Order 1988 or is a person to whom the
document may otherwise lawfully be issued or passed on.

LADIES AND GENTLEMEN:
 
   
     The undersigned hereby tenders to the Company the aggregate principal
amount of Old Notes indicated in this Letter of Transmittal, upon the terms and
subject to the conditions of the Exchange Offers. Subject to, and effective
upon, the acceptance for exchange of the Old Notes tendered hereby, the
undersigned hereby sells, assigns and transfers to, or upon the order of, the
Company all right, title and interest in and to such Old Notes as are being
tendered hereby and hereby irrevocably constitutes and appoints the Exchange
Agent as attorney-in-fact of the undersigned with respect to such Old Notes,
with full power of substitution (such power of attorney being an irrevocable
power coupled with an interest), to: (a) deliver such Old Notes in registered
certificated form, or transfer ownership of such Old Notes through book-entry
transfer at the Book-Entry Transfer Facility, to or upon the order of the
Company, upon receipt by the Exchange Agent, as the undersigned's agent, of the
same aggregate principal amount of New Notes; and (b) receive, for the account
of the Company, all benefits and otherwise exercise, for the account of the
Company, all rights of beneficial ownership of the Old Notes tendered hereby in
accordance with the terms of the Exchange Offers.
    
 
   
     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Old Notes
tendered hereby and that the Company will acquire good, marketable and
unencumbered title thereto, free and clear of all security interests, liens,
restrictions, charges, encumbrances, conditional sale agreements or other
obligations relating to their sale or transfer, and not subject to any adverse
claim when the same are accepted by the Company. The undersigned hereby further
represents that any New Notes acquired in exchange for Old Notes tendered hereby
will have been acquired in the ordinary course of business of the person
receiving such New Notes, whether or not such person is the undersigned, that
neither the holder of such Old Notes nor any such other person is engaged in, or
intends to engage in, a distribution of such New Notes, or has an arrangement or
understanding with any person to participate in the distribution of such New
Notes, and that neither the holder of such Old Notes nor any such other person
is an "affiliate," as defined in Rule 405 under the Securities Act of 1933, as
amended (the "Securities Act"), of the Company. The undersigned has read and
agrees to all of the terms of the Exchange Offers.
    
 
   
     The undersigned also acknowledges that the Company is making these Exchange
Offers in reliance on the position of the staff of the Securities and Exchange
Commission (the "Commission"), as set forth in certain interpretive letters
issued to third parties in other transactions. Based on the Commission
interpretations, the Company believes that the New Notes issued in exchange for
the Old Notes pursuant to the Exchange Offers may be offered for resale, resold
and otherwise transferred by holders thereof (other than a broker-dealer who
purchased Old Notes directly from the Company for resale pursuant to Rule 144A
under the Securities Act or any other available exemption under the Securities
Act or any such holder that is an "affiliate" of the Company within the meaning
of Rule 405 under the provisions of the Securities Act) without further
compliance with the registration and prospectus delivery provisions of the
Securities Act, provided that such New 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, a distribution of such New Notes and have no arrangement with any
person to participate in the distribution of such New Notes. However, the
Company does not intend to request the Commission to consider, and the
Commission has not considered, the Exchange Offers in the context of an
interpretive letter, and there can be no assurance that the staff of the
Commission would make a similar determination with respect to the Exchange
Offers as in other circumstances.
    
 
   
     If the undersigned is not a broker-dealer, the undersigned represents that
it is not engaged in, and does not intend to engage in, a distribution of New
Notes and has no arrangement or understanding to participate in a distribution
of New Notes. If any holder is an affiliate of the Company, is engaged in or
intends to engage in or has any arrangement or understanding with respect to the
distribution of the New Notes to be acquired pursuant to the Exchange Offers,
such holder (i) could not rely on the applicable interpretations of the staff of
the Commission and (ii) must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any resale
transaction. If the undersigned is a broker-dealer that will receive New Notes
for its own account in exchange for Old Notes acquired as a result of
market-making or other trading activities (a "Participating Broker-Dealer"), it
represents that the Old Notes to be exchanged for the New Notes were acquired by
it as a result of market-making or other trading activities and acknowledges
that it will deliver a prospectus in connection with any resale of such New
Notes; however, by so acknowledging and by delivering a prospectus, such
Participating Broker-Dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.
    
 
   
     The Company has agreed that, subject to the provisions of the 1997 Notes
Registration Rights Agreement or 1998 Notes Registration Rights Agreement, as
the case may be, the Prospectus, as it may be amended or supplemented from time
to time, may be used by a Participating Broker-Dealer in connection with resales
of New Notes received in exchange for Old Notes which were acquired by such
Participating Broker-Dealer for its own account as a result of market-making or
other trading activities, for a period ending 180 days after the Expiration
Date, or, if earlier, when all such New Notes have been disposed of by such
Participating Broker-Dealer. In that regard, each Participating Broker-Dealer by
tendering such Old Notes and executing this Letter of Transmittal, agrees that,
upon receipt of notice from the Company of the occurrence of any event or the
discovery of any fact which makes any statement contained or incorporated by
reference in the Prospectus untrue in any material respect or which causes the
Prospectus to omit to state a material fact necessary in
    
<PAGE>   4
 
   
order to make the statements contained or incorporated by reference therein, in
light of the circumstances under which they were made, not misleading, such
Participating Broker-Dealer will suspend the sale of New Notes pursuant to the
Prospectus until the Company has amended or supplemented the Prospectus to
correct such misstatement or omission and has furnished copies of the amended or
supplemented Prospectus to the Participating Broker-Dealer or the Company has
given notice that the sale of the New Notes may be resumed, as the case may be.
If the Company gives such notice to suspend the sale of the New Notes, it shall
extend the 180-day period referred to above during which Participating
Broker-Dealers are entitled to use the Prospectus in connection with the resale
of New Notes by the number of days during the period from and including the date
of the giving of such notice to and including the date when Participating
Broker-Dealers shall have received copies of the supplemented or amended
Prospectus necessary to permit resales of the New Notes or to and including the
date on which the Company has given notice that the sale of New Notes may be
resumed, as the case may be.
    
 
   
     The undersigned will, upon request, execute and deliver any additional
documents deemed by the Company to be necessary or desirable to complete the
sale, assignment and transfer of the Old Notes tendered hereby. All authority
conferred or agreed to be conferred in this Letter of Transmittal and every
obligation of the undersigned hereunder shall be binding upon the successors,
assigns, heirs, executors, administrators, trustees in bankruptcy and legal
representatives of the undersigned and shall not be affected by, and shall
survive, the death or incapacity of the undersigned. This tender may be
withdrawn only in accordance with the procedures set forth in "The Exchange
Offers -- Withdrawal Rights" section of the Prospectus.
    
 
     Unless otherwise indicated herein in the box entitled "Special Issuance
Instructions" below, please deliver the New Notes (and, if applicable,
substitute certificates representing Old Notes for any Old Notes not exchanged)
in the name of the undersigned or, in the case of a book-entry delivery of Old
Notes, please credit the account indicated above maintained at the Book-Entry
Transfer Facility. Similarly, unless otherwise indicated under the box entitled
"Special Delivery Instructions" below, please send the New Notes (and, if
applicable, substitute certificates representing Old Notes for any Old Notes not
exchanged) to the undersigned at the address shown above in the box entitled
"Description of Old Notes."

                           (SEE INSTRUCTIONS 3 AND 4)
 
   
     Unless otherwise indicated in the box entitled "Special Issuance
Instruction" or in the box entitled "Special Delivery Instructions" in this
Letter of Transmittal, certificates for New Notes delivered in exchange for
tendered Old Notes, and any Old Notes delivered herewith but not exchanged, will

New Note is to be mailed to someone other than the person(s) signing this Letter
of Transmittal or to person(s) signing this Letter of Transmittal at an address
different than the address shown on this Letter of Transmittal, the appropriate

Issuance Instruction" or the box entitled "Special Issuance Instruction" or the
box entitled "Special Delivery Instructions" in this Letter of Transmittal,
signature(s) on this Letter of Transmittal must be guaranteed by an Eligible

     To be completed ONLY if the New Notes issued in consideration of Old Notes
exchanged, or certificates for Old Notes in a principal amount not surrendered
for exchange, are to be mailed to someone other than the undersigned or to the
undersigned at an address other than that below.

through an Eligible Institution, (ii) on or prior to the Expiration Date, the
Exchange Agent must have received from the holder and the Eligible Institution a
properly completed and duly executed Notice of Guaranteed Delivery (by facsimile
transmission, mail or hand delivery) setting forth the name and address of the
holder of Old Notes, the certificate number or numbers of the tendered Old
Notes, and the principal amount of tendered Old Notes, stating that the tender
is being made thereby and guaranteeing that, within five New York Stock Exchange
trading days after the Expiration Date, the certificates for the tendered Old
Notes, or a Book-Entry Confirmation of such Old Notes, a duly executed Letter of
Transmittal and any other required documents will be deposited by the Eligible
Institution with the Exchange Agent, and (iii) such properly completed and
executed documents required by the Letter of Transmittal, as well as the
certificates for the tendered Old Notes in proper form for transfer (or
Book-Entry Confirmation of such Old Notes into the Exchange Agent's account at
DTC) must be received by the Exchange Agent within five New York Stock Exchange
trading days after the Expiration Date. Any holder who wishes to tender Old
Notes pursuant to the guaranteed delivery procedures described above must ensure
that the Exchange Agent receives the Notice of Guaranteed Delivery and Letter of
Transmittal relating to such Old Notes prior to 5:00 p.m., New York City time,
on the Expiration Date for the Exchange offer with respect to such Old Notes.
    
 
   
THE METHOD OF DELIVERY OF THIS LETTER, THE OLD NOTES AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE ELECTION AND RISK OF THE TENDERING HOLDERS, BUT THE DELIVERY

AGENT. IF OLD NOTES ARE SENT BY MAIL, IT IS SUGGESTED THAT THE MAILING BE MADE

EXCHANGE AGENT PRIOR TO 5:00 P.M., NEW YORK CITY TIME, ON THE EXPIRATION DATE.
See "The Exchange Offers" section of the Prospectus.
    
 
     DO NOT SENT THIS LETTER OF TRANSMITTAL OR ANY OLD NOTES TO THE COMPANY.
 
2. PARTIAL TENDERS (NOT APPLICABLE TO HOLDERS OF OLD NOTES WHO TENDER BY
BOOK-ENTRY TRANSFER).
 
     If less than the entire principal amount of any submitted Old Note is to be
tendered, the tendering holder(s) should fill in the aggregate principal amount
to be tendered in the box above entitled "Description of Old Notes -- Aggregate
Principal Amount of Old Notes Tendered." A reissued certificate representing the
balance of non-tendered principal of any submitted Old Notes will be sent to
such tendering holder, unless otherwise provided in the appropriate box of this
Letter of Transmittal, promptly after the Expiration Date. THE ENTIRE PRINCIPAL
AMOUNT OF ANY OLD NOTES DELIVERED TO THE EXCHANGE AGENT WILL BE DEEMED TO HAVE
BEEN TENDERED UNLESS OTHERWISE INDICATED.
 
3. SIGNATURES ON THIS LETTER; ASSIGNMENTS AND ENDORSEMENT; GUARANTEE OF
SIGNATURES.
 
     If this Letter of Transmittal is signed by the registered holder of the Old
Notes tendered hereby, the signature must correspond exactly with the name as
written on the face of the Old Notes without any change whatsoever.
 
     If any tendered Old Notes are owned or record by two or more joint owners,
all such owners must sign this letter of Transmittal.
 
     If any tendered Old Notes are registered in different names on several Old
Notes, it will be necessary to complete, sign and submit as many separate copies
of this Letter of Transmittal as there are different registrations of Old Notes.
<PAGE>   8
 
     When this Letter of Transmittal is signed by the registered holder(s) of
the Old Notes specified herein and tendered hereby, no endorsements of the
submitted Old Notes or separate instruments of assignment are required. If,
however, the New Notes are to be issued, or any untendered Old Notes are to be
reissued, to a person other than the registered holder(s), then endorsements of
any Old Notes transmitted hereby or separate instruments of assignment are
required. Signatures on such Old Notes must be guaranteed by an Eligible
Institution.
 
     If this Letter of Transmittal is signed by a person other than the
registered holder(s) of any Old Notes specified herein, such Old Notes must be
endorsed or accompanied by appropriate instruments of assignment, in either case
signed exactly as the name of the registered holder appears on the Old Notes and
the signatures of such Old Notes must be guaranteed by an Eligible Institution.
 
     If this Letter of Transmittal or any Old Notes or instruments of assignment
are signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and, unless waived by
the Company, proper evidence satisfactory to the Company of their authority to
so act must be submitted.
 
     Endorsements on Old Notes or signatures on instruments of assignment
required by this Instruction 3 must be guaranteed by a firm which is a member of
a registered national securities exchange or a member of the National
Association of Securities Dealers, Inc., by a commercial bank or trust company
having an office or correspondent in the United States or by an "eligible
guarantor" institution within the meaning of Rule 17Ad-15 under the Securities
Exchange Act of 1934 (the "Eligible Institution").
 
   
     Signatures of this Letter of Transmittal need not be guaranteed by a
Eligible Institution, provided the Old Notes are tendered: (i) by a registered
holder of Old Notes (which term, for purposes of the Exchange Offers, includes
any participant in the Book-Entry Transfer Facility system whose name appears on
a security position listing as the holder of such Old Notes) who has not
completed the box entitled "Special Issuance Instructions" or "Special Delivery
Instructions" on this Letter of Transmittal, or (ii) for the account of an
Eligible Institution.
    
 
4. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.
 
     Tendering holders of Old Notes should indicated in the applicable box the
name and address to which new Notes issued pursuant to the Exchange Offer and/or
substitute certificates evidencing Old Notes not exchanged are to be issued or
sent, if different from the name or address of the person signing this Letter of
Transmittal. In the case of Issuance in a different name, the Employer
Identification of Social Security Number of the person named must also be
indicated. A holder of Old Notes tendering Old Notes by book-entry transfer may
request that New Notes and Old Notes not exchanged be credited to such account
maintained at the Book-Entry Transfer Facility as such holder of Old Notes may
designate hereon. If no such instructions are given, such New Notes and Old
Notes not exchanged will be returned to the name or address of the person
signing this Letter of Transmittal or credited to the account listed beneath the
box entitled "Description of Old Notes," as the case may be.
 
5. TAX IDENTIFICATION NUMBER.
 
     Federal income tax law generally requires that a tendering holder whose Old
Notes are accepted for exchange must provide the Company (as payor) with such
Holder's correct Taxpayer Identification Number ("TIN") on Substitute Form W-9
above, which, in the case of a tendering holder who is an individual, is his or
her Social Security Number. If the Company is not provided with the Current TIN
or an adequate basis for an exemption, such tendering holder may be subject to a
$50 penalty imposed by the Internal Revenue Service. In addition, delivery of
New Notes to such tendering holder may be subject to backup withholding in an
amount equal to 31% of all reportable payments made after the exchange. If
withholding results in an overpayment of taxes, a refund may be obtained.
 
     Exempt holders of Old Notes (including, among others, all corporations and
certain foreign individuals) are not subject to these backup withholding and
reporting requirements. See the enclosed Guidelines of Certification of Taxpayer
Identification Number on Substitute Form W-9 (the "W-9 Guidelines") for
additional instructions.
 
   
     To prevent backup withholding, each tendering holder of Old Notes must
provide its correct TIN by completing the "Substitute Form W-9" set forth above,
certifying that the TIN provided is correct (or that such holder is awaiting a
TIN) and that (i) the holder is exempt from backup withholding, (ii) the holder
has not been notified by the Internal Revenue Service that such holder is
subject to a backup withholding as a result of a failure to report all interest
or dividends or (iii) the Internal Revenue Service has notified the holder that
such holder is no longer subject to backup withholding. If the tendering holder
of Old Notes is a nonresident alien or foreign entity not subject to backup
withholding, such holder must give the Company a completed Form W-8, Notice of
Foreign Status. These forms may be obtained from the Exchange Agent. If the Old
Notes are in more than one name or are not in the name of the actual owner, such
holder should consult the W-9 Guidelines for Instructions on applying for a TIN,
check the box in Part 3 of the Substitute Form W-9 and write "applied for" in
lieu of its TIN. Note: checking this box and writing "applied for" on the form
means that such holder has already applied for a TIN or that such holder intends
to apply for one in the near future. If such holder does not provide its TIN to
the Company within 60 days, backup withholding will begin and continue until
such holder furnishes its TIN to the Company.
    
 
6. TRANSFER TAXES.
 
   
     The Company will pay all transfer taxes, if any, applicable to the transfer
of Old Notes to it or its order pursuant to the Exchange Offers. If, however,
New Notes and/or substitute Old Notes not exchanges are to be delivered to, or
are to be registered or issued in the name of, any person other than the
registered holder of the Old Notes tendered hereby, or if tendered Old notes are
registered in the name of any person other than the person signing this Letter
of Transmittal, or if a transfer tax is imposed for any reason other than the
transfer of Old Notes to the Issuer or its order pursuant to the
    
<PAGE>   9
 
   
Exchange Offers, the amount of any such transfer taxes (whether imposed on the
registered holder or any other person) will be payable by the tendering holder.
If satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted herewith, the amount of such transfer taxes will be billed directly to
such tendering holder.
    
 
EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT IS NOT NECESSARY FOR TRANSFER TAX
STAMPS TO BE AFFIXED TO THE OLD NOTES SPECIFIED IN THIS LETTER OF TRANSMITTAL.
 
7. DETERMINATION OF VALIDITY/WAIVER OF CONDITIONS.
 
   
     The Company will determine, in its sole discretion, all questions as to the
form of documents, validity, eligibility (including time of receipt) and
acceptance for exchange of any tender of Old Notes, which determination shall be
final and binding on all parties. The Company reserves the absolute right to
reject any and all tenders determined by it not to be in proper form or the
acceptance of which, or exchange for which, may, in the view of counsel to the
Company, be unlawful. The Company also reserves the absolute right, subject to
applicable law, to waive any of the conditions of the Exchange Offers set forth
in the Prospectus under the caption "The Exchange Offers" or any conditions or
irregularity in any tender of Old Notes of any particular holder whether or not
similar conditions or irregularities are waived in the case of other holders.
    
 
   
     The Company's interpretation of the terms and conditions of the Exchange
Offers (including this Letter of Transmittal and the instructions hereto) will
be final and binding. No tender or Old Notes will be deemed to have been validly
made until all irregularities with respect to such tender have been cured or
waived. Although the Company intends to notify holders of defects or
irregularities with respect to tenders of Old Notes, neither the Company, any
employees, agents, affiliates or assigns of the Company, the Exchange Agent, nor
any other person shall be under any duty to give notification of any
irregularities in tenders or incur any liability for failure to give such
notification.
    
 
8. NO CONDITIONAL TENDERS.
 
     No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering holders of Old Notes, by execution of this Letter of
Transmittal, shall waive any right to receive notice of the acceptance of their
Old Notes for exchange.
 
     Neither the Company, the Exchange Agent nor any other person is obligated
to give notice of any defect or irregularity with respect to any tender of Old
Notes nor shall any of them incur any liability for failure to give any such
notice.
 
9. MUTILATED, LOST, STOLEN OR DESTROYED OLD NOTES.
 
     Any holder whose Old Notes have been mutilated, lost, stolen or destroyed
should contact the Exchange Agent at the address indicated above for further
instructions.
 
10. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.
 
     Questions relating to the procedure for tendering, as well as requests for
additional copies of the Prospectus and this Letter of Transmittal, may be
directed to the Exchange Agent, at the address and telephone number indicated
above.
