                                  THE COMPANY
 
OVERVIEW OF OUR BUSINESS
 
     Verio is a leading provider of comprehensive Internet services with an
emphasis on serving the small and medium sized business market. We provide our
customers with the telecommunications circuits that permit them to make
connections to and transmissions over the Internet. We also offer Web hosting
services, providing our customers with a presence on the Internet in the form of
a Web site. A Web site, which consists of information unique to each particular
customer that is stored on a computer -- or "server" -- allows the customer to
make information concerning its business, operations, products and services
available broadly over the Internet to other Internet users. Typically, we
provide the computers where our customers' Web site information is stored on a
shared basis with other customers. For our customers with the resources and
desire to provide their own computer equipment and software, we offer
specialized lease facility resources, providing them with space to house their
equipment in one of our secure, controlled facilities. Finally, we offer an
expanding package of enhanced Internet tools, such as electronic
commerce -- enabling our customers to conduct transactions with their customers
and vendors over the Internet -- and secure Internet communication
links -- permitting our customers to engage in private and secure Internet
communication with their employees, vendors, customers and suppliers.
 
     Since our incorporation in March 1996, Verio has grown very rapidly,
establishing a global presence through the acquisition, integration and organic
growth of over 45 local, regional, national and international providers of
Internet connectivity, Web hosting and other enhanced Internet services.
Currently, Verio provides locally based sales and engineering support for our
Internet services in 41 of the top 50 metropolitan statistical areas in the U.S.
and we provide Web hosting services to customers in over 170 countries. Through
the acquisition of iServer, TABNet and Hiway, Verio has established itself as
the largest Web hosting company in the world based on the number of domain names
(such as yourcompany.com) that we host. As of March 31, 1999, including all
acquisitions Verio had completed as of that date, we served over 260,000
customer accounts, including over 180,000 hosted Web sites. For the three months
ended March 31, 1999, we had revenues of approximately $55.1 million.
Approximately half of our current revenue is derived from our Web hosting and
other enhanced value Internet services. With our large existing customer base
and strong, balanced position in both the Internet access and Web hosting
service platforms, we believe that we will be able to derive increasing revenue
from these customers and facilitate our goal of attaining profitability, by
continuing to offer them better performing Web sites, an expanding array of
enhanced value Internet services, and additional high capacity Internet data
transmission capability that is necessary to support these services.
 
     We are continuing to integrate the operations we have acquired onto our
national network and common administrative support services in order to capture
economies of scale, derive operational efficiency and control, and improve the
quality, consistency and scalability of our services. Verio supports and manages
its operations with highly reliable and scalable national infrastructure and
systems, including a "tier one" national network and proprietary Web site
hosting technologies and tools that differentiate our Web hosting services from
other providers. We have developed back-office support services built on high
quality systems for network monitoring and management, billing, customer service
and financial reporting and accounting. The integration of the operations we
have acquired involves:
 
     - Redesigning acquired local networks with overlapping or non-redundant
       circuits.
 
     - Connecting those local telecommunication networks to our national
       telecommunications network and eliminating unnecessary national network
       capacity we acquire.
 
                                        3

     - Centralizing management functions.
 
     - Standardizing and centralizing back-office functions such as billing and
       accounting.
 
     - Converting the brand names of the acquired operations to the Verio brand.
 
     Our significant scale in both Internet access and Web hosting allows us to
provide robust, high-quality, and expandable service platforms which we can
continually expand and enhance in order to provide a complete and evolving range
of business methods or processes to resolve our customers' Internet problems. We
intend to further enhance the value of these platforms by developing, both
internally and through strategic vendor relationships, a further array of
enhanced value, higher margin product and service offerings to continue to
address our ever changing customer demands.
 
     Verio has also established a global sales and marketing engine that is
driven by:
 
     - Direct sales through over 200 sales professionals.
 
     - Over 4,000 resellers in the U.S. and over 170 other countries.
 
     - Preferential marketing agreements with leading Internet on-line
       companies.
 
     - Private label and co-branded distribution relationships with major
       telecommunications companies.
 
     - In-house and outsourced telemarketing operations.

Acceptance of Old Notes and
  Delivery of New Notes....  After the registration statement becomes effective
                             and the exchange offer is completed, we will accept
                             any and all old notes that are properly tendered in

The Exchange Agent.........  U.S. Bank Trust National Association has agreed to
                             serve as the exchange agent in the exchange offer.
                             See "The Exchange Offer -- The Exchange Agent;
                             Assistance."
 
Material Federal Income Tax
  Considerations...........  With respect to the exchange of old notes for new
                             notes:
 
                             - the exchange should not constitute a taxable
                               exchange for U.S. federal income tax purposes;
 
                             - you should not recognize gain or loss upon
                               receipt of the new notes; and
 
                             - you must include interest on the new notes in
                               gross income to the same extent as the old notes.
 
Use of Proceeds............  We will receive no proceeds from the exchange
                             offer. Net proceeds from the sale of the old notes
                             were approximately $389.0 million. As of March 31,
                             1999, we had used the net proceeds as follows:
 
                             - Acquisitions and long-term
                             investments                        $201.5       52%
 
                             - General working capital          $ 72.6       19%
 
                             - Cash, securities, and short-term
                             investments                        $114.9       29%
 
                             See "Use of Proceeds."
 
Fees and Expenses..........  We will bear all expenses for the completion of the
                             exchange offer and compliance with the registration
                             rights agreement. The expenses of the exchange
                             offer are estimated to be approximately $450,000.
                             We also will pay certain transfer taxes to the
                             extent applicable to the exchange offer. See "The
                             Exchange Offer -- Fees and Expenses."
 
Accrued Interest...........  Interest will accrue on the new notes at a rate of
                             11 1/4% per annum. If your old notes are accepted
                             for exchange you will receive interest accrued on
                             your old notes from the date of original issuance
                             or date of the last interest payment, to, but not
                             including, the date of issuance of your new notes.
                             Interest on your old notes will cease to accrue on
                             the day before your new notes are issued. See
                             "Description of the Notes -- Maturity, Interest and
                             Principal."
 
Resales of New Notes.......  Based on an interpretation by the Securities and
                             Exchange Commission set forth in no-action letters
                             issued to third parties, we believe that you may
                             resell or otherwise transfer new notes issued
                             pursuant to the exchange offer in exchange for old
                             notes. However, there are exceptions to this
                             general statement. You may not freely transfer the
                             new notes if:
 
                             - you are an "affiliate" of Verio within the
                               meaning of Rule 405 under the Securities Act of
                               1933,

                             - you are a broker-dealer who acquired the old
                               notes directly from us without compliance with
                               the registration and prospectus delivery
                               provisions of the Securities Act,
 
                             - you did not acquire the new notes in the ordinary
                               course of your business, or
 
                             - you have engaged in, intend to engage in, or have
                               an arrangement or understanding with any person
                               to participate in the distribution of the new
                               notes.
 
                             Any holder subject to any of the exceptions above
                             and each participating broker-dealer that receives
                             new notes for its own account in the exchange offer
                             in exchange for old notes that were acquired as a
                             result of market-making, must comply with the
                             registration and prospectus delivery requirements
                             of the Securities Act in connection with the resale
                             of the new notes.
 
Effect of Not Tendering Old
  Notes for Exchange.......  If you do not tender your old notes or your old
                             notes are not properly tendered, the existing
                             transfer restrictions will continue to apply. We
                             will have no further obligations to provide for the
                             registration under the Securities Act of your old
                             notes. Your old notes will, following the
                             expiration date, bear interest at the same rate as
                             the new notes.

                            DESCRIPTION OF NEW NOTES
 
     The form and terms of the new notes and the old notes will be identical,
except that:
 
        (1) the new notes have been registered under the Securities Act and,
     therefore, will not bear legends restricting their transfer; and
 
        (2) the holders of the new notes will not be entitled to further
     registration rights under the registration rights agreement.
 
     The new notes will evidence the same debt as the old notes and will be
entitled to the benefits of the indenture under which the old notes were issued.
 
     The exchange offer will be considered completed once we deliver to the
exchange agent new notes in the same aggregate principal amount as the aggregate
principal amount of old notes that are validly tendered by holders. See "The
Exchange Offer -- Procedures for Tendering Old Notes" and "Description of the
Notes."
 
Notes Offered..............  $400.0 million aggregate principal amount of
                             11 1/4% Senior Notes due 2008.
 
Maturity...................  December 1, 2008.
 
Interest Payment Dates.....  June 1 and December 1, commencing June 1, 1999.
 
Ranking....................  The old notes and the new notes will be senior
                             unsecured obligations ranking equally with all our
                             existing and future unsecured and unsubordinated
                             debt including the $100.0 million outstanding
                             principal amount of 13 1/2% Senior Notes due 2004
                             and the $175.0 million outstanding principal amount
                             of 10 3/8% Senior Notes due 2005, and senior to all
                             our existing and future subordinated debt. The old
                             notes and the new notes will be junior to all our
                             secured debt to the extent of the value of the
                             assets securing such debt and structurally
                             subordinated to indebtedness of our subsidiaries.
                             At March 31, 1999 we had:
 
                             - approximately $21.0 million of secured
                               indebtedness outstanding to which holders of the
                               notes would be effectively subordinated in right
                               of payment; and
 
                             - approximately $14.7 million of subsidiary
                               indebtedness to which holders of notes would be
                               structurally subordinated; all of which is
                               included in the secured long-term figure above.
 
                             See "Description of the Notes -- General."
 
Sinking Fund...............  None.
 
Optional Redemption........  On or after December 1, 2003, we may redeem some or
                             all of the notes at specific redemption prices
                             described in this prospectus, plus accrued
                             interest. See "Description of the
                             Notes -- Redemption -- Optional Redemption."
 
                             On or prior to December 1, 2001, we also may be
                             able to redeem up to 35% of the original aggregate
                             principal amount of the notes at a redemption price
                             of 111.250% of the principal amount, plus accrued
                             and unpaid interest. See "Description of the
                             Notes -- Redemption -- Optional Redemption."
 
Change of Control..........  In the event of a change of control, we will be
                             required to make an offer to purchase the notes at
                             a purchase price equal to 101% of the principal
                             amount thereof, plus accrued and unpaid interest.
                             Furthermore, we

                             would be required to repay any funds drawn under a
                             bank facility in the event of a change of control.
                             See "Risk Factors -- We may not have the ability to
                             raise the funds necessary to finance the change of
                             control offer which may be required by the
                             indenture" and "Description of the Notes -- Certain
                             Covenants -- Change of Control."
 
Certain Covenants..........  The indenture governing the new notes will, among
                             other things, restrict our ability to:
 
                             - borrow money;
 
                             - make restricted payments;
 
                             - permit liens to exist;
 
                             - change our business;
 
                             - issue guarantees;
 
                             - sell certain assets or merge with or into other
                               companies;
 
                             - pay dividends;
 
                             - restrict issuances and sales of preferred stock
                               by restricted subsidiaries;
 
                             - engage in transactions with affiliates;
 
                             - designate or create unrestricted subsidiaries;
                               and
 
                             - make investments.
 
                             These covenants are subject to important exceptions
                             and qualifications. See "Description of the
                             Notes -- Certain Covenants."
 
Exchange Rights............  Holders of the new notes will not be entitled to
                             any exchange or registration rights. This exchange
                             offer is intended to satisfy our obligation under
                             the registration rights agreement. We will have no
                             further obligations to register any of the old
                             notes not tendered once the exchange offer is
                             completed. See "Risk Factors -- There may be
                             adverse consequences if you fail to exchange your
                             old notes."

                      SUMMARY CONSOLIDATED FINANCIAL DATA
                   (Amounts in Thousands, Except Share Data)
 
     The summary historical consolidated financial data as of December 31, 1998,
and for the period from inception, March 1, 1996, to December 31, 1996 and the
years ended December 31, 1997 and 1998 have been derived from our audited
Consolidated Financial Statements included elsewhere in this prospectus. The
summary historical consolidated financial data as of March 31, 1999 and for the
three months ended March 31, 1998 and 1999 have been derived from our unaudited
Consolidated Financial Statements, also included in this prospectus.
 
     The information contained below should be read in conjunction with the
"Selected Consolidated Financial and Operating Data," "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and our
Consolidated Financial Statements and the notes thereto included elsewhere in
this prospectus. Results of operations for the period from inception to December
31, 1996, the years ended December 31, 1997 and 1998, and the three months ended
March 31, 1999 are not necessarily indicative of results of operations for
future periods. Our development and expansion activities, including
acquisitions, during the periods shown below may significantly affect the
comparability of this data from one period to another.
 
     The unaudited pro forma statement of operations for the year ended December
31, 1998 gives effect to the Hiway acquisition as if it had occurred on January
1, 1998.
 
     We define Earnings before Interest, Taxes, Depreciation and Amortization as
earnings (loss) from operations before interest, taxes, depreciation,
amortization and provision for loss on write-offs of investments in Internet
service providers and fixed assets and includes non-cash stock option
compensation and severance costs. The primary measure of operating performance
is net earnings (loss) and not Earnings before Interest, Taxes, Depreciation and
Amortization. Although Earnings before Interest, Taxes, Depreciation and
Amortization is a measure commonly used in our industry, it should not be
considered as an alternative to net earnings (loss), as an indicator of
operating performance, or as an alternative to cash flows from operating
activities. Both net earnings (loss) and cash flows from operating activities
are determined in accordance with generally accepted accounting principles. In
addition, our definition of Earnings before Interest, Taxes, Depreciation and
Amortization may not be comparable to other similarly titled measures of other
companies.

     For purposes of presenting capital expenditures, we have excluded equipment
and leasehold improvements acquired in our business acquisitions.

                                  RISK FACTORS
 
     Before you participate in the exchange offer, you should be aware that
there are various risks, including the ones listed below. You should carefully
consider these risk factors and the other information contained in this
prospectus in evaluating the exchange offer.
 
WE HAVE A HISTORY OF LOSSES AND LIMITED OPERATING AND FINANCIAL DATA
 
     We have incurred net losses since our inception in March 1996. For the
period from inception to December 31, 1996, we had a loss of $(5.1) million and
for the years ended December 31, 1997 and 1998, we had losses of $(46.1) million
and $(122.0) million, respectively. Because we have a relatively short operating
history, there is little operating and financial data about us and this makes an
evaluation of our business operations and prospects difficult. We have
experienced revenue growth on an annual basis with revenue increasing from $2.4
million from the period of our inception on March 1, 1996 to December 31, 1996
to approximately $35.7 million in 1997, and to approximately $120.7 million in
1998. However, we have incurred losses and experienced negative Earnings before
Interest, Taxes, Depreciation and Amortization during each of those periods. We
expect to continue to operate at a net loss and experience negative Earnings
before Interest, Taxes, Depreciation and Amortization in the near term as we
continue to expand our business and integrate our operations. We have incurred
net losses attributable to common stockholders of $(5.1) million, $(46.3)
million, $(122.0) million and $(45.1) million and have incurred negative
Earnings before Interest, Taxes, Depreciation and Amortization of $(5.6)
million, $(29.7) million, $(51.3) million and $(7.9) million for each of the
years ended December 31, 1996, 1997 and 1998, and the three months ended March
31, 1999, respectively. At March 31, 1999, we had an accumulated deficit of
approximately $218.6 million. We cannot assure you that we will be able to
achieve or sustain profitability or a positive amount of Earnings before
Interest, Taxes, Depreciation and Amortization.
 
WE EXPECT CONTINUING LOSSES
 
     We expect to incur significant additional losses and to generate negative
operating cash flow in the foreseeable future. We will continue to use
significant amounts of cash as we continue our acquisition and integration
efforts, to build out our national network operations, expand and enhance our
product and service offerings, and further establish our brand name recognition.
The extent to which we experience negative cash flow will depend upon a number
of factors, including the following:
 
     - the number and size of any additional acquisitions and investments;
 
     - the expense and time required to integrate prior and future acquired
       operations;
 
     - the time and effort required to capture operating efficiencies;
 
     - our ability to generate increased revenues and cash flow;
 
     - the amount of our expenditures at the corporate and national level; and
 
     - potential regulatory developments that may apply to our operations.
 
WE CANNOT ASSURE YOU THAT WE WILL BE PROFITABLE
 
     In order to achieve profitability, Verio must develop and market products
and services which gain broad commercial acceptance. We cannot assure you that
we will ever achieve broad commercial acceptance or profitability. Although we
have experienced significant growth in revenues on an annual basis, we do not
believe that this growth rate is necessarily indicative of future operating
results. We cannot assure that we will achieve or sustain positive operating
cash flow or generate income in the future. It is possible that we may never
achieve profitability on a quarterly or annual basis.
 
                                       13
<PAGE>   14
 
WE HAVE SUBSTANTIAL DEBT WHICH MAY IMPACT OUR FUTURE OPERATIONS AND AFFECT OUR
ABILITY TO MEET OUR DEBT OBLIGATIONS
 
     We are highly leveraged and have substantial amounts of outstanding debt.
At March 31, 1999 our total long term liabilities were approximately $690.3
million representing 75% of our total capitalization, and our interest expense
for the three months ended March 31, 1999 was approximately $20.4 million. In
addition, we have obtained a $70.0 million revolving credit facility from a
group of lending banks. We have not drawn any funds from this credit facility.
 
     High levels of debt have had and could have several important effects on
our future operations. Some of these consequences include the following:
 
     - A substantial portion of our cash flow from operations must be used to
       pay interest on our debt and will not be available for other business
       purposes; of the $64.2 million cash flow used by our operations for the
       year ended December 31, 1998, $27.2 million, or approximately 42%, was
       used to pay interest on our debt. Of this amount, 57% was used on the
       $100.0 million outstanding principal amount of 13 1/2% Senior Notes due
       2004 -- which we refer to in this prospectus as the 1997 Notes; 34% was
       used on the $175.0 million outstanding principal amount of 10 3/8 %
       Senior Notes due 2005 -- which we refer to in this prospectus as the
       March 1998 Notes; and 9% related to capital leases and other. In 1999,
       interest on our debt will continue to be a significant use of cash; and
 
     - Covenants imposed under certain of the financing agreements limit our
       ability to borrow additional funds, dispose of assets and affects our
       flexibility with respect to changes in our business, including possible
       acquisitions and capital expenditures.
 
     Our ability to meet our debt obligations and to reduce our total debt
depends on our future operating performance and on economic, financial,
competitive, regulatory and other factors. Many of these factors are beyond our
control. We believe that our existing current assets combined with working
capital from each of operations, existing credit facilities, capital lease
financings and proceeds of future equity or debt financings will be adequate to
meet our financial obligations. We cannot assure, however, that our business
will generate sufficient cash flow due to the various risk factors described or
that future financings will be available to provide sufficient proceeds to meet
these obligations or to service our total debt. In particular, our cash flow may
not be sufficient to pay:
 
     - $13.5 million in annual interest on the 1997 Notes. Interest on these
       notes is paid from an escrow account until June 2000 when the interest
       escrow arrangement terminates.
 
     - $18.2 million in annual interest on the March 1998 Notes;
 
     - $45.0 million in annual interest on the notes; or
 
     - any debt obligations we may incur under the credit facility, if drawn
       upon.
 
WE ARE SUBJECT TO RESTRICTIVE COVENANTS THAT LIMIT OUR FLEXIBILITY
 
     Our $70.0 million bank credit facility may only be used if we meet certain
financial tests and prohibits us from paying dividends or repurchasing our
capital stock without the lenders' consent. Failure to comply with these terms
would entitle the secured lenders to foreclose on certain of our assets,
including the capital stock of our subsidiaries and our capacity agreement with
Qwest. The secured lenders would be repaid from the proceeds of the liquidation
of those assets before the assets would be available for distribution to the
holders of Verio's capital stock. In addition, the terms of the credit facility,
as well as the 1997 Notes, the March 1998 Notes and the notes, impose
limitations on our ability to incur additional debt, and therefore may make it
difficult for us to borrow in the future. The restrictive covenants in our
existing financial arrangements other than the Notes are subject to change
without consent of the holders of the notes and hence may become more or less
restrictive in the future if such changes are implemented. The existing
financial arrangements require, and future financing arrangements are likely to
require, that we maintain certain financial ratios and comply with certain
covenants further restricting our ability to incur additional debt, pay
dividends or make other restricted payments, sell assets, enter into affiliate
transactions or take other actions. In addition, our ability to satisfy these
restrictive covenants may be affected by events beyond our control. As a result
we cannot assure you that we will be able to continue to satisfy these
covenants.
 
                                       14
<PAGE>   15
 
WE MAY BE UNABLE TO RAISE ADDITIONAL FUNDS THAT WE WILL NEED TO REMAIN
COMPETITIVE
 
     Verio depends on a number of different financing sources to fund its growth
and continued losses from operations. However, we cannot assure you that we will
be able to raise such funds on favorable terms. In the event that we are unable
to obtain such additional funds on acceptable terms, we may be unable or
determine not to take advantage of new opportunities or take other actions that
otherwise might be important to our operations.
 
     We expect to make significant capital expenditures in order to maintain our
competitive position and continue to meet the increasing demands for service
quality, availability and competitive pricing. In addition to our continuing
acquisition efforts, we currently expect that our significant capital
expenditures will include the following:
 
     - network equipment;
 
     - network operating centers;
 
     - network monitoring equipment;
 
     - information technology systems; and
 
     - customer support systems.
 
     We believe that we will have a reasonable degree of flexibility to adjust
the amount and timing of these capital expenditures. However, we may need to
raise additional funds in order to take advantage of unanticipated
opportunities, such as acquisition opportunities that may arise in the U.S. and
internationally. In addition, we may need to raise additional funds to develop
new products or otherwise respond to changing business conditions or
unanticipated competitive pressures. We may be required to delay or abandon some
of our planned future expansion or expenditures if we fail to raise sufficient
funds.
 
OUR OPERATING RESULTS FLUCTUATE DUE TO A VARIETY OF FACTORS AND ARE NOT A
MEANINGFUL INDICATOR OF FUTURE PERFORMANCE
 
     Our operating results have fluctuated in the past and may fluctuate
significantly in the future depending upon a variety of factors, including the
incurrence of capital costs and the introduction of new products and services.
Additional factors that may contribute to variability of operating results
include:
 
     - the pricing and mix of services we offer;
 
     - our customer retention rate;
 
     - changes in pricing policies and product offerings by our competitors;
 
     - growth in demand for network and Internet access services;
 
     - one-time costs associated with acquisitions and regional consolidation;
       and
 
     - general telecommunications services' performance and availability.
 
     We also have experienced seasonal variation in Internet use and, therefore,
revenue streams may fluctuate accordingly. In response to competitive pressures,
we may take certain pricing or marketing actions that could have a material
adverse effect on our business, financial condition and results of operations.
As a result, variations in the timing and amounts of revenues could have a
material adverse effect on our quarterly operating results. Therefore, we
believe that period-to-period comparisons of our operating results are not
necessarily meaningful and cannot be relied upon as indicators of future
performance. If our operating results in any future period fall below the
expectations of securities analysts and investors, the market price of our
securities would likely decline.
 
OUR SUCCESS IS HIGHLY DEPENDENT ON THE GROWTH OF OUR EXISTING INTERNET ACCESS
AND WEB HOSTING CORE SERVICES, AND ON OUR ABILITY TO EXPAND OUR SERVICE
OFFERINGS AND DISTRIBUTION CHANNELS
 
     While we continue to seek to deepen and broaden our market presence in the
U.S. and internationally through acquisitions, our success is highly dependent
on the growth of our existing Internet access and Web
 
                                       15
<PAGE>   16
 
hosting core service platforms. We expect to drive this internal growth by
expanding and enhancing our product service base with additional enhanced value
Internet service capabilities and by establishing further distribution
capabilities. To a certain extent we may develop these further product and
distribution capabilities internally, but expect that primarily we will look to
formulate strategic relationships with various vendors and distribution
partners. Accordingly, it will be important that we either develop these
capabilities internally or identify suitable potential product and service
vendors and distributors with whom we are able to complete agreements on
acceptable terms. We expect that competition for strategic relationships with
key vendors and potential distributors could be significant, and that we may
have to compete with other companies with greater financial and other resources
to obtain these important relationships. We cannot assure you that we will be
able to identify suitable partnering candidates or be able to complete
agreements on acceptable terms with these parties.
 
OUR SUCCESS DEPENDS ON OUR ABILITY TO SUCCESSFULLY INTEGRATE THE OPERATIONS WE
HAVE ACQUIRED AND MAY ACQUIRE IN THE FUTURE
 
     A key element of our business strategy is to grow through acquisitions, and
our success depends in large part on our ability to integrate the operations and
management of the independent Internet operations we have acquired and those we
may acquire in the future. If we fail to integrate our acquisitions successfully
this may result in significant operating inefficiencies, which in turn may
adversely affect our operating results. We have to expend substantial
managerial, operating, financial and other resources to integrate these
businesses and implement our business model. In particular, to integrate our
newly acquired Internet operations successfully, we must:
 
     - install and standardize adequate operational and control systems;
 
     - deploy standard equipment and telecommunications facilities;
 
     - employ qualified personnel to provide technical and marketing support in
       new as well as existing locations;
 
     - eliminate redundancies in overlapping network systems and personnel;
 
     - incorporate acquired technology and products into our existing service
       offerings;
 
     - implement and maintain uniform standards, procedures and policies;
 
     - standardize marketing and sales efforts under the common Verio brand; and
 
     - continue the expansion of our managerial, operational, technical and
       financial resources.
 
     The process of consolidating and integrating acquired operations takes a
significant period of time, places a significant strain on resources, and could
prove to be even more expensive and time-consuming than we have predicted. We
may increase expenditures in order to accelerate the integration and
consolidation process with the goal of achieving longer-term cost savings and
improved profitability. These expenses may include the following, among others:
eliminating redundant staffing positions; relocating personnel; canceling
overlapping Internet access contracts; closing down redundant points of presence
facilities; upgrading systems; and integrating these acquired providers' onto
our network, customer care, billing, financial and other national support
systems. For example, we recorded a one-time charge of approximately $1.9
million in 1998 relating to the elimination of 250 redundant positions. We
cannot assure you that our projected long-term cost savings and improvements in
profitability can or will be realized. We also cannot assure you that customer
support resources will be sufficient to manage the growth in our business or
that we will be successful in implementing our expansion program in whole or in
part.
 
     In addition, future acquisitions could materially adversely affect our
operating results as a result of dilutive issuances of equity securities and the
incurrence of additional debt. In addition, the purchase price for many of these
acquired businesses likely will significantly exceed the fair values of the net
assets of the acquired businesses. As a result, material goodwill and other
intangible assets would be required to be recorded which would result in
significant amortization charges in future periods. These charges, in addition
to
 
                                       16
<PAGE>   17
 
the financial impact of such acquisitions, could have a material adverse effect
on our business, financial condition and results of operations.
 
WE FACE CERTAIN PARTICULAR RISKS IN OUR INTEGRATION OF THE HIWAY OPERATIONS
 
     We face certain key risks in successfully completing the integration of the
recently completed acquisition of Best Internet Communications, Inc., which does
business as Hiway Technologies, Inc., and which we refer to as Hiway. This
acquisition was a substantial transaction for Verio. Difficulties we may
experience associated with the integration of Hiway's operations with our
existing business may have an adverse impact on Verio. The key integration
challenges we face in connection with the Hiway acquisition include:
 
     - the acquired operations, facilities, equipment, service offerings,
       networks, technologies, brand names, and sales, marketing and service
       development efforts may not be effectively integrated with our existing
       operations;
 
     - anticipated cost savings may not be realized;
 
     - integration efforts may divert our resources from our existing business;
 
     - standards, controls, procedures and policies may not be maintained; and
 
     - employees who are key to the acquired operations may choose to leave.
 
     Any of these difficulties could interrupt our business and operations. We
cannot assure you that we will effectively realize any of the anticipated
benefits from the integration of the Hiway acquisition. Specifically with
respect to Hiway, we expect to incur significant integration expenses. Factors
that could increase these costs include:
 
     - unexpected employee turnover;
 
     - unforeseen delays in addressing duplicate facilities and the associated
       costs of hiring temporary employees; and
 
     - additional fees and charges to obtain consents, regulatory approvals or
       permits.
 
     Hiway was formed in May 1998 through a merger of Best Internet and Hiway.
Because the Best/Hiway Merger was accomplished fairly recently, the integration
of the operations of those two companies was not completed prior to our
acquisition of Hiway. It is likely that this integration effort will continue.
In the course of that integration effort, it is possible that facts or
circumstances may be discovered that we did not know at the time we executed the
agreement to acquire Hiway. We cannot assume that difficulties will not be
encountered in integrating Hiway, or that the specific benefits expected from
the Best/Hiway Merger will be achieved or that we will realize any of those
anticipated benefits.
 
WE FACE RISKS ASSOCIATED WITH ACQUISITIONS GENERALLY
 
     We expect to continue our acquisition and expansion strategy. Additional
acquisitions could have a material impact on the financial information we have
provided. Future acquisitions could materially adversely affect our operating
results as a result of dilutive issuances of equity securities and the
incurrence of additional debt. In addition, the purchase price for many of these
acquired businesses likely will significantly exceed the current fair values of
the net assets of the acquired businesses. As a result, material goodwill and
other intangible assets would be required to be recorded which would result in
significant amortization charges in future periods. These charges, in addition
to the financial impact of such acquisitions, could have a material adverse
effect on our business, financial condition and results of operations.
 
     Up to now, we have recorded all business acquisitions under the purchase
method of accounting. With the acquisition of Hiway, which was completed on
January 5, 1999, we expect to record gross goodwill totaling approximately
$244.0 million, which will be amortized over a ten-year period from the
acquisition date. We cannot assure you of the number, timing or size of future
acquisitions, or the effect that any such acquisitions might have on our
operating or financial results.
 
                                       17
<PAGE>   18
 
THE FINANCIAL INFORMATION CONCERNING BUSINESSES WE ACQUIRE MAY BE INACCURATE
 
     Many of the Internet businesses we have acquired did not have audited
financial statements, and this may be true for subsequent acquisitions as well.
These companies have had varying degrees of internal controls and detailed
financial information. Therefore, the financial information we are able to
provide in this prospectus includes financial information concerning certain
recently completed acquisitions for which audited financial statements may not
be available. Our subsequent audits of these recently acquired companies may
reveal significant issues with respect to revenues, expenses and liabilities,
contingent or otherwise, of any of these providers.
 
     We have completed valuations of certain of our acquisitions, including NTX,
Inc. -- which does business as TABNet -- and Hiway. This process included
evaluation of in-process research and development programs. We could not
allocate a meaningful value to, and therefore will not be recording any charge
to operations for, in-process research and development relating to these
acquisitions. We have followed the Securities and Exchange Commission's
guidelines in the valuation of in-process research and development.
 
OUR RAPID GROWTH PUTS A SIGNIFICANT STRAIN ON OUR RESOURCES
 
     As a result of our acquisition strategy, we have been growing and expect to
continue to grow rapidly. This rapid growth has placed, and is likely to
continue to place, a significant strain on our managerial, operating, financial
and other resources, including our ability to ensure customer satisfaction. For
example, as our customer base grows, and their need for high capacity Internet
data transmission capability expands, we will need to acquire substantial
network capacity to support their needs. Our expansion efforts also require
significant time commitments from our senior management and places a strain on
their ability to manage our existing business. We also may be required to manage
multiple relationships with third parties as we expand our enhanced value
service offerings, including Web hosting. Our future performance will depend, in
part, upon our ability to manage this growth effectively. To that end, we will
have to undertake the following improvements, among others:
 
     - implement additional management information systems capabilities;
 
     - further develop our operating, administrative and financial and
       accounting systems and controls;
 
     - improve coordination between our engineering, accounting, finance,
       marketing and operations; and
 
     - hire and train additional personnel.
 
WE DEPEND UPON THIRD PARTY CHANNEL PARTNERS IN MARKETS WHERE WE DO NOT HAVE A
DIRECT SALES FORCE
 
     We depend on third party channel partners to stimulate demand for our
products and services where we do not have a direct sales force. These channel
partners include computer and telecommunications resellers, value-added
resellers, original equipment manufacturers, systems integrators, Web designers
and advertising agencies. If we fail to gain commercial acceptance in certain
markets channel partners may discontinue their relationships with us. Conflicts
may develop between our direct sales force efforts and those of our channel
partners as well as among different channel partners. These conflicts could
affect our relationship with various channel partners. The loss of channel
partners, the failure of such parties to perform under agreements with us, or
the inability to attract other channel partners with the expertise and industry
experience required to market our products and services could adversely affect
us. Furthermore, sales through channel partners are usually at discounted rates.
Therefore, the resulting revenues and gross margins will be less than if we had
sold the same services directly.
 
WE FACE RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS AND EXPANSION
 
     With our acquisitions of Internet Server, Inc. -- which we refer to as
iServer, TABNet, WWW-Service Online-Dienstleistungen AG, a German Web hosting
company, and Hiway, we now provide Web hosting services to customers in over 170
countries. We expect to continue to expand in these and other international
markets. The rate of development and adoption of the Internet has been slower
outside the U.S., and the cost
 
                                       18
<PAGE>   19
 
of transmitting data over the Internet outside the U.S. has been higher, which
may adversely affect our ability to expand operations, and increase our costs of
operations internationally. We cannot assure you that acceptance of the Internet
or demand for Internet access, Web hosting and other enhanced value Internet
services will increase significantly in any international markets.
 
     We may need to enter into joint ventures or other outsourcing agreements
with third parties, acquire complementary businesses or operations, or establish
or maintain new operations outside the U.S. in order to conduct our foreign
operations successfully. However, we cannot assure you that we will be able to
obtain the permits and operating licenses required to operate, to hire and train
employees or to market, sell and deliver high quality services in these markets.
In addition to the uncertainty as to our ability to expand our international
presence, there are certain risks inherent in doing business on an international
level. These risks include:
 
     - unexpected changes in or delays resulting from regulatory requirements,
       tariffs, customs, duties and other trade barriers;
 
     - difficulties in staffing and managing foreign operations;
 
     - longer payment cycles and problems in collecting accounts receivable;
 
     - political instability, expropriation, nationalization, war, insurrection
       and other political risks;
 
     - fluctuations in currency exchange rates and foreign exchange controls
       which restrict or prohibit repatriation of funds;
 
     - technology export and import restrictions or prohibitions;
 
     - employment laws and practices in foreign countries;
 
     - delays from customs brokers or government agencies;
 
     - differences in technology standards;
 
     - seasonal reductions in business activity during the summer months in
       Europe and certain other parts of the world; and
 
     - potentially adverse tax consequences.
 
     We cannot assure you that these factors will not have an adverse effect on
our future international operations. In addition, we cannot assure you that
foreign laws or administrative practice relating to taxation, foreign exchange,
regulatory or other matters will not change. Any such change could adversely
affect us.
 
     Effective January 1, 1999, 11 of the 15 member countries of the European
Union established fixed conversion rates between their existing sovereign
currencies and the euro, and adopted the euro as their common legal currency. We
have not commenced any assessment of the effects or potential impact that the
euro conversion would have on us. Furthermore, certain foreign governments, such
as Germany, have enforced laws and regulations related to content distributed
over the Internet that are more strict than those currently in place in the U.S.
This could adversely affect our investment in international operations such as
WWW.
 
WE FACE A HIGH LEVEL OF COMPETITION IN THE INTERNET SERVICES INDUSTRY
 
     The tremendous growth and potential market size of the Internet access
market has attracted many new start-ups as well as existing businesses from the
telecommunications, cable, and technology industries as there are no substantial
barriers to entry in this market. As a result, the market for Internet access
and related services is extremely competitive. Verio anticipates that
competition will continue to intensify as the use of the Internet grows. Current
and prospective competitors include:
 
     - national, regional and local Internet service providers;
 
     - global, national, and regional long distance and local exchange
       telecommunications companies;
                                       19
<PAGE>   20
 
     - cable television companies;
 
     - direct broadcast satellite and wireless communications providers;
 
     - on-line service providers; and
 
     - Web hosting providers, and providers of other enhanced value Internet
       services.
 
     Verio believes that the following are the primary competitive factors in
this market:
 
     - Maintaining a secure and reliable national network with sufficient
       capacity, quality of service and scalability to support continued growth.
 
     - Maintaining a knowledgeable and effective sales force and implementing
       broad and effective distribution channels.
 
     - Providing knowledgeable and capable technical support personnel, and
       prompt and efficient customer care services.
 
     - Maintaining Internet system engineering and other technical expertise.
 
     - Offering competitive prices.
 
     - Making timely introductions of new products and services.
 
     - Having sufficient financial resources.
 
     - Having a recognized and trusted brand name.
 
     Many of our competitors have significantly greater market presence, brand
recognition, and financial, technical, network capacity and personnel resources
than we do. All of the major long distance companies, also known as
interexchange carriers, offer Internet access services and compete with us. The
recent sweeping reforms in the federal regulation of the telecommunications
industry have created greater opportunities for local exchange carriers,
including the regional bell operating companies, to enter the Internet access
market. In order to address the Internet access requirements of the current
business customers of long distance and local carriers, there is a move toward
integrating horizontally through acquisitions of, joint ventures with, and the
wholesale purchase of Internet access from, Internet service providers by these
telecommunications companies. In addition, many of the major cable companies and
other alternative service providers -- such as those companies utilizing
wireless terrestrial and satellite-based service technologies -- have announced
their plans to offer Internet access and related services. Accordingly, we
expect that we will experience increased competition from traditional and
emerging telecommunications providers. Many of these companies, in addition to
their substantially greater network coverage, market presence, and financial,
technical and personnel resources, also have large existing commercial customer
bases. Furthermore, they may have the ability to bundle Internet access with
basic local and long distance telecommunications services. This bundling of
services may have an adverse effect on our ability to compete effectively with
them and may result in pricing pressure on us that would adversely affect our
business, financial condition and results of operations.
 
     The recent deployment and further planned deployment of broadband services
or high capacity data transmission capabilities by cable and telephone companies
through new technologies such as cable modems and various digital subscriber
lines technologies also creates further competitive pressure in Verio's
business. While these providers initially targeted the residential consumer,
more recently a number of digital subscriber lines providers also have announced
their intent to offer digital subscriber lines services to our target business
market. This may significantly affect the pricing of our Internet access service
offerings. Similar to the co-marketing arrangement which we entered into with
NorthPoint Communications in early 1999, a number of digital subscriber lines
providers have launched their services in conjunction with Internet service
providers, allowing those providers to offer Internet access over digital
subscriber lines circuits. These digital subscriber lines circuits, which
provide higher speed and lower latency Internet connections than a standard
dial-up phone connection, compete with our dedicated connectivity offerings.
 
                                       20
<PAGE>   21
 
     As we continue to expand internationally, we will encounter new
competitors. In some cases, we will be forced to compete with and buy services
from government-owned or subsidized telecommunications providers. Some of these
providers may enjoy a monopoly on telecommunications services essential to our
business. We cannot assure you that we will be able to purchase these services
at a reasonable price or at all. In addition to the risks associated with our
local competitors, foreign competitors may pose an even greater risk, as they
may possess a better understanding of their local markets and better working
relationships with local infrastructure providers and others. We cannot assure
you that we can obtain similar levels of local knowledge. Failure to obtain that
knowledge could place us at a significant competitive disadvantage.
 
WE DEPEND UPON OUR NETWORK INFRASTRUCTURE
 
     Verio's success depends upon its ability to implement and expand its
national network infrastructure and support services at an acceptable cost. This
may require us to enter into additional agreements with providers of
infrastructure capacity and equipment and support services. We cannot assure you
that any of these agreements can be obtained on satisfactory terms and
conditions. We also anticipate that future expansions and adaptations of our
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 our customers' product and service requirements. This will
require substantial financial, operational and managerial resources. We cannot
assure you that we will be able to expand or adapt our network infrastructure to
meet the industry's evolving standards or our customers' growing demands and
changing requirements on a timely or cost-effective basis, or at all. Also, we
may not be able to deploy successfully any expanded and adapted network
infrastructure.
 
OUR NETWORK SYSTEM COULD FAIL OR SHUTDOWN WHICH COULD NEGATIVELY IMPACT OUR
REVENUES
 
     Our success depends upon our ability to deliver reliable, high-speed access
to the Internet and upon the ability and willingness of our telecommunications
providers to deliver reliable, high-speed telecommunications service through
their networks. Our network, and other networks providing services to us, are
vulnerable to damage or cessation of operations from fire, earthquakes, severe
storms, power loss, telecommunications failures and similar events, particularly
if the events occur within a high traffic location of the network. We have
designed our network to minimize the risk of such system failure, for instance,
with redundant circuits among points of presence facilities to allow traffic
rerouting. In addition, we perform lab and field testing before integrating new
and emerging technology into the network, and we engage in capacity planning.
Nonetheless, we cannot assure that we will not experience failures or shutdowns
relating to individual point of presence facilities or even catastrophic failure
of the entire network.
 
     While historically Verio has not, as a general matter, offered our
customers a service level warranty, certain of the companies we acquired did
offer various warranties under their customer contracts. For example, Hiway
historically has offered its customers a service level warranty, under which
Hiway commits that a customer's Web site will be available at least 99.9% of the
time in each calendar month for as long as the customer is using the services.
If uptime falls below this level in any month, the customer is entitled to
certain service credits for that month. By acquiring Hiway, Verio inherited
these warranty obligations. More and more, our customers are requiring that we
provide a standard service level warranty for our services, and many of our
competitors are beginning to offer this. As a result, in order to remain
competitive, Verio now expects to implement a standard policy under which we
offer such a warranty to our customers. To the extent that Verio or Hiway is
providing such a service level warranty in the future, we could experience a
material decline in our revenues in connection with any significant system
downtime experienced by our customers or other material changes associated with
such warranty coverage.
 
     We carry business personal property insurance at both scheduled locations
and unscheduled locations, with a blanket property limit of $10.0 million per
location and business interruption insurance with a blanket limit of $2.0
million per location. This insurance may not be adequate or available to
compensate us. In addition, we generally attempt to limit our liability to
customers by contractually disclaiming liability or limiting liability to a
usage credit based upon the amount of time that the system was down. We cannot
 
                                       21
<PAGE>   22
 
assure, however, that such limitations of liability will be enforceable. In any
event, significant or prolonged system failures or shutdowns could damage our
reputation and cause us to lose our customers.
 
ALTHOUGH WE HAVE IMPLEMENTED NETWORK SECURITY MEASURES, OUR NETWORK MAY
EXPERIENCE SECURITY BREACHES
 
     The ability to provide secure transmission of information over the Internet
is a significant barrier to electronic commerce and communications. We have
implemented certain network security measures, such as limiting physical and
network access to our routers. Nonetheless, we cannot assure that our network
infrastructure will not be vulnerable to computer viruses, break-ins and similar
disruptive problems caused by our customers or other Internet users. Computer
viruses, break-ins or other problems caused by third parties could lead to
interruptions, delays or cessation in service to our customers. Furthermore,
such incidents could deter potential customers and adversely affect existing
customer relationships.
 
     Security problems represent an ongoing threat to public and private data
networks. Attacks upon the security of Internet sites and infrastructure
continue to be reported to organizations such as the CERT Coordination Center at
Carnegie Mellon University, which facilitates responses of the Internet
community to computer security events. Addressing problems caused by computer
viruses, break-ins or other problems caused by third parties could have a
material adverse effect on us, and the cost of eliminating these security
breaches could be prohibitively expensive.
 
WE MAY BE LIABLE TO CUSTOMERS FOR SECURITY BREACHES
 
     The security services that we offer in connection with our customers'
networks cannot assure complete protection from computer viruses, break-ins and
other disruptive problems. Inappropriate use of the Internet by third parties
could also potentially jeopardize the security of confidential information
stored in the computer systems of our customers. Although we attempt to limit
contractually our liability in such instances, the occurrence of these problems
may result in claims against or liability on our part. Such claims, regardless
of their ultimate outcome, could result in costly litigation and adversely
affect our business or reputation or our ability to attract and retain
customers. Moreover, until more consumer reliance is placed on security
technologies available, the security and privacy concerns of existing and
potential customers may inhibit the growth of the Internet service industry and
our customer base and revenues.
 
OUR COSTS WILL INCREASE IF WE FAIL TO MAINTAIN OUR PEERING RELATIONSHIPS
 
     The establishment and maintenance of peering relationships with other
Internet service providers is necessary in order to exchange traffic with other
Internet service providers without having to pay transit costs. The basis on
which the large national Internet service providers make peering available or
impose settlement charges is evolving. Recently, companies that have previously
offered peering have cut back or eliminated peering relationships and are
establishing new, more restrictive criteria for peering, requiring substantial
data transmission volume and broad national scale. Global network capabilities
also may become a requirement. If increasing requirements associated with
maintaining peering with the major national Internet service providers develop,
we may have to comply in order to maintain our peering relationships. Failure to
maintain peering relationships or establish new ones, if necessary, would cause
additional operating expenditures which would adversely affect us.
 
WE DEPEND ON THE INTERNET AND INTERNET INFRASTRUCTURE DEVELOPMENT
 
     Our products and services are targeted toward users of the Internet, which
has experienced rapid growth. Critical issues concerning the commercial use of
the Internet remain unresolved and may impact the growth of Internet use,
especially in our target business market. 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:
 
     - inconsistent quality of service;
 
     - lack of availability of cost-effective, high-speed options;
 
                                       22
<PAGE>   23
 
     - 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 use of the Internet to date. 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. 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. 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 are not
broadly accepted, our business, operating results and financial condition will
be materially adversely affected. In addition, the rate of development and
adoption of the Internet has been slower outside of the United States and the
cost of transmitting data over the Internet has been higher. The recent growth
in the use of the Internet has caused frequent periods of performance
degradation, requiring the upgrade of routers and switches, telecommunications
links and other components forming the infrastructure of the Internet by
providers and other organizations with links to the Internet. Any perceived
degradation in the performance of the Internet as a whole could undermine the
benefits of our services. Consequently, the emergence and growth of the market
for our services is dependent on improvements being made to the entire Internet
infrastructure to alleviate overloading and congestion.
 
WE MUST KEEP UP WITH TECHNOLOGY TRENDS AND EVOLVING INDUSTRY STANDARDS
 
     The market for Internet access and related services is characterized by
rapidly changing technology, evolving industry standards, changes in customer
needs and frequent new product and service introductions. Our future success
will depend, in part, on our ability to effectively use leading technologies, to
continue to develop our technical expertise, to enhance our current services, to
develop new products and services that meet changing customer needs, and to
influence and respond to emerging industry standards and other technological
changes on a timely and cost-effective basis. We cannot assure that we will be
successful in accomplishing these tasks or that such new technologies or
enhancements will achieve market acceptance. We believe that our ability to
compete successfully is also dependent upon the continued compatibility and
interoperability of our services with products and architectures offered by
various vendors. We cannot assure that we will be able to effectively address
the compatibility and interoperability issues raised by technological changes or
new industry standards. In addition, we cannot assure that services or
technologies developed by others will not render our services or technology
uncompetitive or obsolete. For example, our services rely on the continued
widespread commercial use of transmission control protocol/Internet protocol.
Alternative open and proprietary protocol standards that compete with
transmission control protocol/Internet protocol, including proprietary protocols
developed by IBM and Novell, Inc., have been or are being developed. The failure
of the market for business-related Internet solutions to continue to develop
would adversely impact our business financial condition and result of
operations.
 
                                       23
<PAGE>   24
 
WE FACE POTENTIAL LIABILITY FOR INFORMATION DISSEMINATED THROUGH OUR NETWORK
 
     The law relating to liability of Internet service providers for information
carried on or disseminated through their networks is not completely settled. A
number of lawsuits have sought to impose such liability for defamatory speech
and infringement of copyrighted materials. The U.S. Supreme Court has let stand
a lower court ruling which held that an Internet service provider was protected
from liability for material posted on its system by a provision of the
Communications Decency Act. However, the findings in that case may not be
applicable in other circumstances. Other courts have held that on-line service
providers and Internet service providers may, under certain circumstances, be
subject to damages for copying or distributing copyrighted materials. Certain
provisions of the Communications Decency Act, which imposed criminal penalties
for using an interactive computer service for transmitting obscene or indecent
communications, have been found unconstitutional by the U.S. Supreme Court.
However, on October 21, 1998, new federal legislation was enacted that requires
limitations on access to pornography and other material deemed "harmful to
minors" within the meaning contained in the legislation. This legislation has
been successfully attacked in the U.S. district court as a violation of the
First Amendment. We are unable to predict the outcome of this case on appeal.
The imposition upon Internet service providers or web server hosts of potential
liability for materials carried on or disseminated through their systems could
require us to implement measures to reduce our exposure to such liability. These
measures may require that we spend substantial resources or discontinues certain
product or service offerings. Any of these actions could have a material adverse
effect on our business, operating results and financial condition.
 
     The law relating to the regulation and liability of Internet access
providers in relation to information carried or disseminated also is undergoing
a process of development in other countries. For example, the European Union
recently enacted its own privacy regulations. Decisions, laws, regulations and
other activities regarding regulation and content liability may significantly
affect the development and profitability of companies offering on-line and
Internet access services.
 
     We carry an errors and omissions insurance policy. This insurance may not
be adequate or available to compensate us for all liability that may be imposed.
 
WE MAY BECOME SUBJECT TO GOVERNMENT REGULATION
 
     Although we are not currently subject to direct government regulation other
than regulations applicable to businesses generally, changes in the regulatory
environment relating to the Internet connectivity market could affect our
pricing. For example, proposed regulations at the Federal Communications
Commission would require discounted Internet connectivity rates for schools and
libraries. Due to the increasingly widespread use of the Internet, it is
possible that additional laws and regulations may be adopted. Such additional
laws could cover issues such as content, user pricing, privacy, libel,
intellectual property protection and infringement, and technology export and
other controls. We may be subject to similar or other laws and regulations in
non-U.S. jurisdictions.
 
     Moreover, the Federal Communications Commission continues to review its
regulatory position on the usage of the basic network and communications
facilities by Internet service providers. Although in an April 1998 report the
Federal Communications Commission determined that Internet service providers
should not be treated as telecommunications carriers and therefore not
regulated, it is expected that future Internet service provider regulatory
status will continue to be uncertain. Indeed, in that report, the Federal
Communications Commission concluded that certain services offered over the
Internet such as phone-to-phone Internet protocol telephony, may be functionally
indistinguishable from traditional telecommunications service offerings and
their non-regulated status may have to be re-examined.
 
     Changes in the regulatory structure and environment affecting the Internet
access market, including regulatory changes that directly or indirectly affect
telecommunications costs or increase the likelihood of competition from regional
bell operating companies or other telecommunications companies, could adversely
affect us. Although the Federal Communications Commission has decided not to
allow local telephone companies to impose per-minute access charges on Internet
service providers, and that decision has been upheld by the reviewing court,
further regulatory and legislative consideration of this issue is likely. In
                                       24
<PAGE>   25
 
addition, some telephone companies are seeking relief through the Federal
Communications Commission and state regulatory agencies. Such rules, if adopted,
are likely to have a greater impact on consumer-oriented Internet access
providers than on business-oriented Internet service providers such as Verio.
Nonetheless, the imposition of access charges would affect our costs of serving
dial-up customers and could have a material adverse effect on our business,
financial condition and results of operations.
 
WE DEPEND UPON SUPPLIERS, WHO ARE OFTEN OUR COMPETITORS, AND HAVE LIMITED
SOURCES OF SUPPLY FOR CERTAIN PRODUCTS AND SERVICES
 
     We rely on other companies to supply certain key components of our network
infrastructure, however, the quantity and quality of components we demand is
available only from limited sources. For example, we currently rely on Cisco
Systems to supply routers critical to our network. We could be adversely
affected if routers from Cisco were to become unavailable on commercially
reasonable terms. Qwest, Sprint, MCI and MFS, who sell products and services
that compete with ours, also are our primary providers of data communications
facilities and network capacity. We also are dependent upon local exchange
carriers, which often are our competitors. Local exchange carriers provide
telecommunications services and lease physical space to us for routers, modems
and other equipment. Often we experience delays in the delivery and installation
of telecommunications services, which can lead to the loss of existing or
potential customers. We cannot assure that, on an ongoing basis, we will be able
to obtain such services cost-effectively and on the scale and within the time
frames we require, or at all. Failure to obtain or to continue to make use of
such services would have a material adverse effect on its business, operating
results and financial condition.
 
WE DEPEND ON KEY PERSONNEL AND COULD BE AFFECTED BY THE LOSS OF THEIR SERVICES
BECAUSE OF THE LIMITED NUMBER OF QUALIFIED PEOPLE IN OUR INDUSTRY
 
     Competition for qualified employees and personnel in the Internet services
industry is intense and there are a limited number of people with knowledge of
and experience in the Internet service industry. The process of locating
personnel with the combination of skills and attributes required to carry out
our strategies is often lengthy. Our success depends to a significant degree
upon our ability to attract and retain qualified management, technical,
marketing and sales personnel and upon the continued contributions of such
people. Our employees may voluntarily terminate their employment with us at any
time. We cannot assure you that we will be successful in attracting and
retaining qualified executives and personnel. The loss of the services of key
personnel, or the inability to attract additional qualified personnel, could
have a material adverse effect on its business, financial condition or results
of operations.
 
THERE IS NO PUBLIC MARKET FOR THE NEW NOTES
 
     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 us that they intend to make a market in the new notes, however, they
are not obligated to do so. In addition, such market-making will be subject to
the limits imposed by the Securities Act and Section 21E of the Securities
Exchange Act of 1934, as amended. We cannot assure you that any market will
develop for the new notes. If a market does develop, the new notes may trade at
prices lower than the initial offering price of the old notes and liquidity may
be limited. If a market for the new notes does not develop, you may not be able
to resell your notes for an extended period of time, if at all. Also, the market
for the new notes may also be materially and adversely affected by declines in
the market for high-yield securities generally. We do not intend to apply for
listing of the new notes on any securities exchange or on any automated
quotation system.
 
YOU MUST COMPLY WITH RESTRICTIONS OF THE EXCHANGE OFFER
 
     If you fail to follow the proper procedure for the exchange offer, your old
notes may not be exchanged for new notes. New notes will be issued in exchange
for old notes only after timely receipt by the exchange agent of a properly
completed and duly executed letter of transmittal, including all other documents
required by the letter of transmittal. Therefore, if you desire to tender your
old notes for new notes you should allow sufficient time to ensure timely
delivery. Neither the exchange agent nor Verio is under any duty to give
                                       25
<PAGE>   26
 
notification of any defects or irregularities with respect to the tenders of old
notes. Each broker-dealer that receives new notes for its own account in the
exchange offer must deliver a prospectus in connection with any resale of such
new notes. See "The Exchange Offer -- Resales of the New Notes" and "Plan of
Distribution."
 
THERE MAY BE ADVERSE CONSEQUENCES IF YOU FAIL TO EXCHANGE YOUR OLD NOTES
 
     If you do not exchange your old notes for new notes, the restrictions on
transfer of your old notes contained in the legend on the old notes will
continue to apply. In general, the old notes may not be offered or sold, unless
registered or exempt from registration under the Securities Act and applicable
state securities laws. To the extent that old notes are tendered and accepted in
the exchange offer, the trading market for untendered and tendered but
unaccepted old notes could be adversely affected. Generally, if you do not
exchange your old notes, any rights you might have under the registration rights
agreement with us will terminate.
 
WE MAY NOT HAVE THE ABILITY TO RAISE THE FUNDS NECESSARY TO FINANCE THE CHANGE
OF CONTROL OFFER WHICH MAY BE REQUIRED BY THE INDENTURE
 
     Upon the occurrence of a change of control as defined in the indenture
governing the notes, we would be required to make an offer to purchase any or
all of the notes at a purchase price equal to 101% of the principal amount plus
accrued and unpaid interest. However, our ability to repurchase the notes upon a
change of control may be limited by the terms of our then existing contractual
obligations and those of our subsidiaries. We may not have adequate financial
resources to effect such a purchase, and there can be no assurance that we would
be able to obtain the necessary resources through a refinancing of the notes to
be purchased or otherwise. If we fail to repurchase all of the notes tendered
for purchase upon the occurrence of a change of control, such failure will
constitute and event of default under the indenture.
 
     With respect to the sale of assets referred to in the definition of change
of control, the phrase "all or substantially all" as used in the definition
varies according to the facts and circumstances of the subject transaction, has
no clearly established meaning under the relevant law and is subject to judicial
interpretation. Accordingly, in some circumstances there may be a degree of
uncertainty in asserting whether a particular transaction would involve a
disposition of "all or substantially all" of the assets of a person and
therefore it may be unclear whether a change of control has occurred and whether
the notes are subject to an offer to purchase.
 
     The change of control provision may not necessarily afford the holders of
the notes protection in the event of a highly leveraged transaction, including a
reorganization, restructuring, merger or other similar transaction involving
Verio that may adversely affect the holders of the notes. These transactions may
not involve a shift in voting power or beneficial ownership or, even if they do,
may not involve a shift of the magnitude required under the definition of change
of control to trigger such provisions. Except as described under "Description of
the Notes -- Change of Control," the indenture governing the notes will not
contain provisions that permit the holders to require us to repurchase or redeem
the notes in the event of a takeover, recapitalization or similar transaction.
 
OUR BUSINESS MAY BE ADVERSELY IMPACTED BY YEAR 2000 ISSUES
 
     We are aware of the issues associated with the programming code in existing
computer systems as the year 2000 approaches. Generally, there is a concern with
whether computer systems will properly recognize date sensitive information when
the year changes to 2000. Systems that do not properly recognize this date could
generate wrong data or fail. The year 2000 problem is pervasive and complex, as
virtually every company's computer operations potentially could be affected in
some way.
 
     We are currently engaged in a phased process to evaluate our internal
status with respect to the year 2000 issue. The first phase, systems assessment,
was completed in the fourth quarter of 1998. Phase two, risk assessment and
contingency planning, is expected to be completed during the second quarter of
1999. Phase three, testing and final verification, is expected to be completed
in the third quarter of 1999.
 
                                       26
<PAGE>   27
 
     We hired outside consultants and used certain designated employees in our
evaluation of possible year 2000 problems. To date, we have not discovered year
2000 issues in the course of our assessment that would have a material adverse
effect on our business, results of operations or financial condition; however,
we cannot assure you that errors or defects would not be discovered in the
future or remain undetected.
 
     Concurrently with the analysis of our internal systems, we have begun to
survey third-party entities with which we transact business, including critical
vendors, suppliers and financial institutions, for year 2000 compliance. With
respect to the most critical vendors, we are in the process of evaluating the
year 2000 preparedness of our telecommunications providers, on which we are
reliant for the network services crucial to our business. We expect to complete
this survey in the second quarter of 1999. If we, or any of our key suppliers or
vendors, fail to mitigate internal and external year 2000 risks, we may
temporarily be unable to provide our services to our customers or engage in
normal business activities which could have a material adverse effect on our
business, financial condition and results of operations.

                               THE EXCHANGE OFFER
 
     The following discussion summarizes the provisions of a registration rights
agreement that we entered into with the initial purchasers of the old notes. It
does not purport to be complete and reference is made to the provisions of the
registration rights agreement, which has been filed as an exhibit to the
registration statement of which this prospectus constitutes a part, and copies
of which are available upon request to Verio.
 
PURPOSE AND EFFECT
 
     The old notes were sold by us to Salomon Smith Barney Inc., Credit Suisse
First Boston Corporation, Donaldson, Lufkin & Jenrette Securities Corporation
and First Union Capital Markets, as initial purchasers, on November 20, 1998.
The initial purchasers subsequently resold the old notes in reliance on Rule
144A under the Securities Act. We entered into a registration rights agreement
with the initial purchasers that requires, among other things, that we:
 
     - file, on or prior to February 18, 1999, a registration statement with the
       Securities and Exchange Commission under the Securities Act concerning
       the exchange offer with respect to the notes;
 
     - use our best efforts (a) to cause the registration statement to be
       declared effective by the Securities and Exchange Commission on or before
       May 17, 1999, and (b) to complete the exchange offer on or before June
       16, 1999; and
 
     - keep the exchange offer 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 is mailed to the holders of the old notes.
 
     The exchange offer is intended to satisfy our obligations under the
registration rights agreement.
 
     By tendering, each registered holder will represent to us that, among other
things:
 
        (1) any new notes received will be acquired by the holder and the
     beneficial owner of the old notes in the ordinary course of business of the
     holder and each beneficial owner;
 
        (2) the holder and the 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;
 
        (3) the holder and the beneficial owner acknowledge and agree that any
     person participating in the 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 Securities and Exchange Commission in its
     no-action letters that are discussed below under "-- Resales of New Notes;"
 
        (4) 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;
 
        (5) the holder and the beneficial owner understand that a secondary
     resale transaction described in clause (3) 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 Securities and
     Exchange Commission; and
 
        (6) neither the holder nor the beneficial owner is an "affiliate," as
     defined under Rule 405 of the Securities Act, of Verio except as otherwise
     disclosed to Verio 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.

CONSEQUENCES OF FAILURE TO EXCHANGE OLD NOTES
 
     After the exchange offer expires, holders of old notes not tendered, or not
properly tendered, will not have any further registration rights. These old
notes will continue to be subject to the existing transfer restrictions.
Accordingly, the liquidity of the market for a holder's old notes could be
adversely affected after the exchange offer expires if such holder elects not to
participate in the exchange offer.
 
TERMS OF THE EXCHANGE OFFER
 
     Upon the terms and subject to the conditions described below, the
registration rights agreement and the accompanying letter of transmittal, we
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 upon satisfaction
or waiver of all the conditions to the exchange offer. The new notes will be
delivered promptly after acceptance of the old notes.
 
     We will issue $1,000 principal amount of new notes in exchange of each
$1,000 principal amount of outstanding old notes accepted in the exchange offer.
You may tender some or all of your old notes in the exchange offer. However, old
notes may be tendered only in integral multiples of $1,000. The new notes will
evidence the same debt as the old notes and will be entitled to the benefits of
the indenture. The form and terms of the new notes are substantially the same as
the form and terms of the old notes, except that:
 
     - the new notes have been registered under the Securities Act and will not
       bear legends restricting their transfer; and
 
     - holders of the new notes generally will not be entitled to certain rights
       under the registration rights agreement, which rights generally will
       terminate upon completion of the exchange offer.
 
     You may withdraw the tender of your old notes at any time prior to 5:00
p.m., New York City time, on the expiration date. The exchange offer is not
conditioned upon any minimum principal amount of old notes being tendered for
exchange. See "-- Conditions of the Exchange Offer."
 
     As of the date of this prospectus, $400.0 million in aggregate principal
amount of the old notes is outstanding. As of March 31, 1999, there was one
registered holder of old notes with 43 Depository Trust Company participants.
Only a holder of the old notes, or such holder's legal representative or
attorney-in-fact, may participate in the exchange offer. There will be no fixed
record date for determining holders of the old notes entitled to participate in
the exchange offer. We believe 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 Verio.
 
     We will be deemed to have accepted validly tendered notes when, as and if
we have given oral or written notice 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 us. Issuances of new notes for old notes that are
accepted in the exchange offer 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 the
Depository Trust Company; provided, however, that we reserve the absolute right
to waive any defects or irregularities in the tender or conditions of the
exchange offer. 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 unaccepted old notes will be returned, without
expense, to the tendering holder as promptly as practicable after the expiration
date.
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
   
     The expiration date shall be June 17, 1999 at 5:00 p.m., New York City
time, unless we decide in our sole discretion to extend the exchange offer, in
which case the expiration date shall be the latest date and time to which the
exchange offer is extended.
    
 
                                       29
<PAGE>   30
 
     In order to extend the exchange offer, we will notify the exchange agent of
any extension by oral or written notice and will make a public announcement,
each prior to 9:00 a.m., New York City time, on the next business day after the
previously scheduled expiration date.
 
     We reserve the right, in our sole discretion, (1) to delay accepting any
old notes, (2) to extend the exchange offer, and (3) to amend the terms of the
exchange offer in any manner. Any such delay in acceptance, extension or
amendment will be followed as promptly as practicable by a public announcement.
If the exchange offer is amended in a manner determined by us to constitute a
material change, we 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 the exchange offer. Modifications of the 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 the
exchange offer.
 
CONDITIONS OF THE EXCHANGE OFFER
 
     The exchange offer is not conditioned upon any minimum principal amount of
the old notes being tendered for exchange. However, the exchange offer is
conditioned upon the declaration by the Securities and Exchange Commission of
the effectiveness of the registration statement of which this prospectus
constitutes a part.
 
ACCRUED INTEREST
 
     The new notes will bear interest at a rate equal to 11 1/4% per annum from
and including their date of issuance. Holders whose old notes are accepted for
exchange will have the right to receive accrued interest from the last date on
which interest was paid on the old notes, or if no interest had been paid on
such old notes, from the date of their original issue, to, but not including,
the date of issuance of the new notes accepted for exchange. Interest accrued on
the old notes at the rate of 11 1/4% per annum, and will cease to accrue on the
day the issuance of the new notes. See "Description of the Notes -- Maturity,
Interest and Principal."
 
PROCEDURE FOR TENDERING OLD NOTES
 
     The tender by a holder and the acceptance by Verio will constitute a
binding agreement between the tendering holder and Verio upon the terms and
subject to the conditions contained in this prospectus and in the accompanying
letter of transmittal.
 
     Except as described below, a holder who wishes to tender old notes in the
exchange offer must transmit such old notes, together with a properly completed
and signed letter of transmittal, including all other documents required by such
letter of transmittal, to the exchange agent 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 the Depository Trust
Company's book-entry transfer facility system may make book-entry delivery of
the old notes by causing the Depository Trust Company to transfer such old notes
into the exchange agent's account in accordance with the Depository Trust
Company'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 the
Depository Trust Company's Automated Tender Offer Program procedures for
transfer and such procedures are complied with prior to 5:00 p.m., New York City
time, on the expiration date.
 
     The Depository Trust Company's Automated Tender Offer Program is the only
method of processing exchange offers through the Depository Trust Company. To
accept the exchange offer through the Automated Tender Offer Program,
participants in the Depository Trust Company must send electronic instructions
to the Depository Trust Company through the Depository Trust Company's
communication system, prior to
 
                                       30
<PAGE>   31
 
5:00 p.m., New York City time, on the expiration date, in place of sending a
signed, hard copy letter of transmittal. The Depository Trust Company is
obligated to communicate those electronic instructions to the exchange agent by
an agent's message. The term "agent's message" means a message transmitted by
the Depository Trust Company received by the exchange agent and forming part of
the book-entry confirmation, which states:
 
     - that the Depository Trust Company has received an express acknowledgment
       from a participant in the Depository Trust Company's Automated Tender
       Offer Program that is tendering old notes which are the subject of such
       book entry confirmation; and
 
     - that such participant has received and agrees to be bound by the terms of
       the letter of transmittal, or, in the case of an agent's message relating
       to guaranteed delivery, that such participant has received, and agrees to
       be bound by the applicable notice of guaranteed delivery, and that the
       agreement may be enforced against such participant.
 
To tender old notes through the Automated Tender Offer Program, the electronic
instructions sent to the Depository Trust Company and transmitted by the
Depository Trust Company 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
are tendered (1) 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 (2) for the
account of an eligible institution, which means 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 U.S. or otherwise is an "eligible guarantor institution"
within the meaning of Rule 17Ad-15 under the Exchange Act.
 
     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 an eligible institution. 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 be endorsed or accompanied by a properly completed
bond power, in form satisfactory to us in our sole discretion, signed by the
registered holder, as such registered holder's name appears on such old notes,
with the signature guaranteed by an eligible institution.
 
     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 us in our sole discretion, which determination will be final and
binding. We reserve the absolute right to reject any and all old notes not
properly tendered and to reject any old notes acceptance of which might, in our
judgment or the judgment of our counsel, be unlawful. We also reserve the
absolute right to waive any defects or irregularities or conditions of the
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 the exchange offer. The interpretation of the terms and
conditions of the exchange offer, including the letter of transmittal and the
instructions thereto, by us will 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 we shall determine.
Although we will use reasonable efforts to notify holders of defects or
irregularities with respect to tenders of old notes, none of Verio, the exchange
agent or any other person shall 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 us,
proper evidence satisfactory to us, in our sole discretion, of such person's
authority to so act must be submitted.
 
                                       31
<PAGE>   32
 
     If you are a beneficial owner of old notes and the old notes are registered
in the name of a broker, dealer, commercial bank, trust company or other
nominee, and you wish to tender old notes in the exchange offer, you should
contact such registered holder promptly and instruct such registered holder to
tender on your behalf. If you are a beneficial owner and you wish to tender
directly, you 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 your name. Beneficial owners should be aware that the transfer
of registered ownership may take considerable time.
 
GUARANTEED DELIVERY PROCEDURES
 
     Holders who wish to tender their old notes and (1) whose old notes are not
immediately available, (2) 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 (3) who cannot complete the procedure for book-entry
transfer on a timely basis, may effect a tender if:
 
        (a) the tender is made by or through an eligible institution and a
     notice of guaranteed delivery is signed by such holder;
 
        (b) on or prior to the expiration date, the exchange agent receives from
     the holder and the eligible institution a properly completed and duly
     executed notice of guaranteed delivery, by facsimile transmission, mail or
     hand delivery, containing the name and address of the holder, 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 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
 
        (c) 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 the Depository Trust Company, is 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. The
Depository Trust Company participants may also submit the notice of guaranteed
delivery through the Automated Tender Offer Program.
 
WITHDRAWAL RIGHTS
 
     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. To withdraw a tender of old notes in
the exchange offer, a written notice must be received by the exchange agent, at
its address set forth on the back cover page of this prospectus, or holders must
comply with the appropriate procedures of the Depository Trust Company's
Automated Tender Offer Program. Any such notice of withdrawal must:
 
     - specify the name of the person having deposited the old notes to be
       withdrawn;
 
     - identify the old notes to be withdrawn, including the certificate number
       or numbers and principal amount of such old notes, as applicable;
 
     - 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 a form
       satisfactory to us in our 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
 
                                       32
<PAGE>   33
 
     - specify the name in which such old notes are to be re-registered, if
       different from the person depositing the old notes to be withdrawn.
 
     Any questions as to the validity, form and eligibility, including time of
receipt, of such notices will be determined by us, in our sole discretion. The
withdrawn old notes will be deemed not to have been validly tendered for
exchange for purposes of the exchange offer. Any old notes which have been
tendered for exchange but which are withdrawn will be returned to the holder
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 "-- Procedure for Tendering Old Notes" at any time on or prior
to the expiration date.

                      Attn: Specialized Finance Department
 
FEES AND EXPENSES
 
     All expenses incurred in completing the exchange offer and complying with
the registration rights agreement, will be borne by Verio, including, without
limitation:
 
     - all applicable Securities and Exchange Commission, stock exchange or
       National Association of Securities Dealers, Inc. registration and filing
       fees;
 
     - 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 National Association of Securities Dealers, Inc.;
 
     - all applicable expenses we incur 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 registration rights agreement;
 
     - all rating agency fees, if any; and
 
     - the fees and disbursements of counsel.
                                       33
<PAGE>   34
 
     We estimate that the amount of these fees and expenses will be
approximately $450,000.
 
     We have not retained any dealer-manager in connection with the exchange
offer and will not make any payments to brokers, dealers others soliciting
acceptance of the exchange offer. We, 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.
 
     We will pay all transfer taxes, if any, applicable to the exchange of old
notes pursuant to the exchange offer. If, however, a transfer tax is imposed for
any reason other than the exchange of old notes pursuant to the exchange offer,
then the amount of any such transfer taxes, whether imposed on the registered
holder or any other persons, will be payable by the tendering holder. If
satisfactory evidence of payment of such taxes or exemption is not submitted
with the letter of transmittal, the amount of such transfer taxes will be billed
directly to such tendering holder.
 
ACCOUNTING TREATMENT
 
     The new notes will be recorded at the same carrying value as the old notes,
as reflected in Verio's accounting records on the date of the exchange.
Accordingly, no gain or loss will be recognized by Verio for accounting
purposes. The expenses of the exchange offer will be amortized over the term of
the new notes.
 
RESALES OF THE NEW NOTES
 
     Based on the position of the staff of the Securities and Exchange
Commission contained in no-action letters issued to third parties, we believe
that the new notes issued pursuant to the exchange offer to any holder of old
notes in exchange for old notes may be offered for resale, resold and otherwise
transferred by such holder 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. This does not apply to a
broker-dealer who purchased old notes directly from Verio for resale pursuant to
Rule 144A under the Securities Act or any other available exemption under the
Securities Act, or a person that is an "affiliate" of Verio within the meaning
of Rule 405 under the Securities Act.
 
     We have not sought our own interpretive letter and there can be no
assurance that the Securities and Exchange Commission would make a similar
determination with respect to the exchange offer. Verio and holders of old notes
are not entitled to rely on interpretive advice provided by the staff or other
persons, which advice was based on the facts and conditions represented in such
letters. However, the exchange offer is 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 the 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 Securities and Exchange Commission enunciated
in Morgan Stanley & Co. Incorporated, available June 5, 1991, and Exxon Capital
Holdings Corporation, available May 13, 1989, or interpreted in the Securities
and Exchange Commission's letter to Shearman and Sterling, available July 2,
1993, or similar no-action or interpretive letters. The holder 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 offer by
holders who are "affiliates" of Verio 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 Verio. The foregoing is a summary only of Rule 144 as it may apply to
affiliates of Verio. 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
 
     We will receive no cash proceeds from the issuance of the new notes
pursuant to the exchange offer.
 
     The exchange offer is intended to satisfy our obligations under the
registration rights agreement. In consideration for issuing the new notes as
contemplated in this prospectus, we 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 registration
rights. The old notes surrendered in exchange for new notes will be retired and
canceled and cannot be reissued. Accordingly, issuance of the new notes will not
increase our total debt.
 
     The net proceeds from the offering of the old notes, after deducting the
initial purchasers' discounts and expenses, were approximately $389.0 million.
The net proceeds from the offering of the old notes have been and continue to be
used to further our 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
our general working capital purposes. Pending application of the proceeds as
described above, we have invested the net proceeds of the issuance of the old
notes in short-term, interest-bearing, investment-grade securities.
 
     As of March 31, 1999, we had used the net proceeds as follows:

                                DIVIDEND POLICY
 
     Verio has never declared or paid any dividends on its common stock and does
not expect to pay dividends in the foreseeable future. Our current policy is to
retain all of our earnings to finance future growth and acquisitions.
Furthermore, the terms of the indentures relating to the notes, the 1997 Notes
and the March 1998 Notes, as well as the $70.0 million revolving credit
facility, place limitations on our ability to pay dividends. Future dividends,
if any, will be at the discretion of our board of directors and will depend
upon, among other things, our operations, capital requirements and surplus,
general financial condition, contractual restrictions and such other factors as
our board may deem relevant. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

                             (Amounts in Thousands)
 
     The following table sets forth the cash and cash equivalents, restricted
cash and securities, long-term debt and capital lease obligations, and the
capitalization of Verio at March 31, 1999.
 
     Stockholders' equity does not include approximately 7.6 million shares of

                      SELECTED CONSOLIDATED FINANCIAL DATA
                   (Amounts in Thousands, Except Share Data)
 
     The selected historical consolidated financial data as of December 31,
1998, and for the period from inception, March 1, 1996, to December 31, 1996 and
the years ended December 31, 1997 and 1998 have been derived from our audited
Consolidated Financial Statements included elsewhere in this prospectus. The
selected historical consolidated financial data as of March 31, 1999 and for the
three months ended March 31, 1998 and 1999 have been derived from our unaudited
Consolidated Financial Statements, also included in this prospectus.
 
     The information contained below should be read in conjunction with the
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and our Consolidated Financial Statements and the notes thereto
included elsewhere in this prospectus. Results of operations for the period from
inception to December 31, 1996, the years ended December 31, 1997 and 1998, and
the three months ended March 31, 1998 and 1999, are not necessarily indicative
of results of operations for future periods. Our development and expansion
activities, including acquisitions, during the periods shown below may
significantly affect the comparability of this data from one period to another.
 
     The unaudited pro forma statement of operations for the year ended December
31, 1998 gives effect to the Hiway acquisition as if it had occurred on January
1, 1998.
 
     We define Earnings before Interest, Taxes, Depreciation and Amortization as
earnings (loss) from operations before interest, taxes, depreciation,
amortization and provision for loss on write-offs of investments in Internet
service providers and fixed assets and includes non-cash stock option
compensation and severance costs. The primary measure of operating performance
is net earnings (loss) and not Earnings before Interest, Taxes, Depreciation and
Amortization. Although Earnings before Interest, Taxes, Depreciation and
Amortization is a measure commonly used in our industry, it should not be
considered as an alternative to net earnings (loss) as an indicator of operating
performance, or as an alternative to cash flows from operating activities. Both
net earnings (loss) and cash flows from operating activities are determined in
accordance with generally accepted accounting principles. In addition, our
definition of Earnings before Interest, Taxes, Depreciation and Amortization may
not be comparable to other similarly titled measures of other companies.
 
     We have not paid any cash dividends on our common stock since our
inception. For purposes of presenting capital expenditures, we have excluded
equipment and leasehold improvements acquired in our business acquisitions.
 
     For the period ended December 31, 1996, the years ended December 31, 1997
and 1998, and the three months ended March 31, 1999, earnings were insufficient
to cover combined fixed charges by $5.8 million, $48.0 million, $112.3 million,
and $45.1 million, respectively. On a unaudited pro forma basis, giving effect
to the Hiway acquisition as if it had occurred on January 1, 1998, earnings
would have been insufficient to cover combined fixed charges by $150.8 million
for the year ended December 31, 1998. Combined fixed charges consist of interest
expense and that portion of rent expense we believe to be representative of
interest, deemed to be one third of rent expense, adjusted for minority
interests.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion and analysis should be read in conjunction with
the financial statements and related notes included elsewhere in this
prospectus. We account for investments in affiliates in which we acquire a
minority interest at cost. We account for investments in affiliates in which we
acquire a majority interest, through the acquisition of net assets, common stock
or convertible preferred stock, and where we exercise significant control over
the operations, using purchase accounting. As such, we consolidate the financial
results of these acquired operations with our financial results. This discussion
contains forward-looking statements based on current expectations, which involve
risks and uncertainties. Actual results and the timing of certain events could
differ materially from the forward-looking statements as a result of a number of
factors including those referred to in Risk Factors.
 
OVERVIEW
 
     Our Company was founded in March 1996. Since then, we have rapidly
established a global presence by acquiring, integrating and growing independent
Internet service providers with a business customer focus. We had, together with
our subsidiaries, total revenue of approximately $55.1 million for the
three-month period ended March 31, 1999.
 
     Our initial strategy was to acquire 51% to 100% of a large regional
Internet service provider, and a minority interest in smaller Internet service
providers within designated geographic regions. We have moved to a strategy of
acquiring 100% of new businesses, although in certain circumstances we continue
to make investments in less than wholly owned companies. During the second
quarter of 1998, we completed the buyout of the remaining equity interests in
all but one of the operations in which we initially acquired less than a 100%
interest. Since then, we have undertaken to consolidate the ownership and
management of the acquired operations into geographic and product based
operating units. In addition, we have integrated their network operations,
customer support, marketing efforts, financial and accounting systems, and other
back-office functions onto our national systems, in order to be more efficient.
Although we have incurred significant one-time costs in these consolidation
efforts, we expect to recognize substantial long-term cost savings as a result.
We have the contractual right to effect the buyout of the one remaining
affiliate in which we do not hold 100% ownership. In 1998 we incurred costs of
approximately $52.0 million, in the aggregate, in connection with a total of 11
buyouts, and approximately $116.1 million for acquisitions, which amounts were
paid in cash, shares of Verio stock and options to acquire stock. As a result of
these acquisitions, and the limited amount of fixed assets required to operate
an affiliate, we recorded significant amounts of goodwill in 1998, in the amount
of $171.5 million.
 
     On July 7, 1998, we completed the acquisition of NTX, Inc., which does
business as TABNet. We paid a purchase price of approximately $45.8 million in
cash to TABNet's shareholders. On January 5, 1999, we closed the acquisition of
Best Internet Communications, Inc., which does business as Hiway Technologies,
Inc., for which we paid total consideration of approximately $176.0 million in
cash and 4.92 million fully diluted shares of our common stock to Hiway's
shareholders, option holders and warrant holders. In connection with the Hiway
acquisition, we expect to record additional goodwill in the amount of
approximately $244.0 million which will increase goodwill significantly in 1999.
 
     To fund our acquisitions and operations, from inception through March 31,
1999 we raised approximately $320.5 million from equity capital financings,
including approximately $120.8 million, after deducting underwriting discounts,
commissions and expenses, in our initial public offering, and approximately
$100.0 million in connection with the sale of our common stock to an affiliate
of Nippon Telegraph and Telephone Corporation, which occurred together with our
initial public offering in May 1998. We also have raised a total of $725.0
million in debt, of which $50.0 million has been repaid. In 1997, we issued
$150.0 million principal amount of 13 1/2% Senior Notes due 2004 to a group of
institutional investors and Brooks Fiber Properties, Inc., $100.0 million of
which remain outstanding following the repurchase of $50.0 million principal
amount of the 1997 Notes previously held by Brooks. We refer to the repurchase
in this prospectus as the refinancing. On March 25, 1998, we sold $175.0 million
principal amount of 10 3/8% Senior
 
                                       39
<PAGE>   40
 
Notes due 2005, a portion of the proceeds of which was used to effect the
refinancing. On November 25, 1998, we sold $400.0 million principal amount of
old notes resulting in net proceeds of approximately $389.0 million. See
"-- Liquidity and Capital Resources."
 
     We have incurred net losses since we were formed. For the period from
inception to December 31, 1996, the years ended December 31, 1997 and 1998, and
the three-month period ended March 31, 1999, we reported net losses of $(5.1)
million, $(46.3) million, $(122.0) million, and $(45.1) million, respectively.
We expect to continue to incur significant additional losses. See "Risk
Factors -- We expect continuing losses."

  REVENUE
 
     Most of our revenue is received from business customers who purchase high
speed Internet connectivity, Web hosting products, and other enhanced value
Internet services. Verio offers a broad range of connectivity options to its
customers including dedicated, digital subscriber line, integrated services
digital network, frame relay and dial-up connections. Connectivity customers
typically sign a contract for one year of service and pay fixed, recurring
monthly service charges plus a one-time setup fee under those agreements. These
charges vary depending on the type of service, the length of the contract, and
local market conditions. Our Web hosting customers also typically sign a
contract for one year of service and pay fixed, recurring monthly service
charges plus a one-time setup fee. These charges vary depending on the amount of
disk space and transit required by the customer. Other enhanced value Internet
services include:
 
     - electronic commerce;
 
     - secure Internet communication links permitting our customers to engage in
       private and secure Internet communication with their employees, vendors,
       customers and suppliers;
                                       40
<PAGE>   41
 
     - security services;
 
     - specialized facility leases for our customers with the resources and
       desire to house their own equipment and software in one of our secure,
       controlled facilities;
 
     - consulting; and
 
     - the sales of equipment and customer circuits.
 
     Revenue for all products is recognized as the service is provided. Amounts
billed relating to future periods are recorded as deferred revenue and amortized
monthly as services are rendered.
 
     In 1997 and 1998, connectivity services generated approximately two-thirds
of total revenue. In 1999 and beyond, revenue from Web hosting and other
enhanced value Internet services is expected to represent approximately 50% or
more of total revenue. The increase in revenue from Web hosting and other
enhanced value Internet services is primarily the result of acquisitions we made
beginning at the end of 1997 and through 1998, including Hiway, that have been
concentrated in these businesses. Verio has experienced some seasonality in its
internal revenue growth, with the period of higher growth being the fall and
winter. Verio's focus is on services that generate recurring revenues from small
and mid-sized business customers. Revenues from business customers currently
represent approximately 90% of revenue, and approximately 80% of revenues are
recurring. No single customer represents more than 2% of revenue.
 
     Total revenue increased 160% from $21.2 million for the three months ended
March 31, 1998 to $55.1 million for the three months ended March 31, 1999.
Acquisitions completed after March 31, 1998 contributed significantly to this
increase.
 
  COST OF SERVICE
 
     Cost of service consists primarily of local telecommunications expense and
Internet access expense. Local telecommunications expense is primarily the cost
of transporting data between Verio's local points of presence and a national
point of presence. Internet access expense is the cost that Verio pays to lease
fiber capacity that it uses to carry its customers' data between national point
of presences on the Internet. Most of the Internet businesses and operations we
have acquired were party to various local telecommunications and Internet access
contracts with third parties when we acquired them. Verio is in the process of
converting that traffic carried by third parties to our own network as those
historic agreements expire. Currently, we expect to have substantially completed
that process for our prior acquisitions by the end of 1999. In March 1998, Verio
signed a 15 year capacity agreement with Qwest Communications Corporation in
order to fix and reduce the per-unit costs we incur to lease fiber. That
capacity agreement was amended in 1999 to further reduce the per-unit costs and
to increase Verio's commitment, which is now to spend a minimum of $160 million
over the first 10 years of the capacity agreement. While we will continue to use
a variety of fiber providers for our national network, we expect to use Qwest
for the majority of our fiber requirements. We have the right to prepay our
minimum commitment under this agreement. Such capitalized costs would be
amortized over the term of the commitment. The amount of the prepayment at March
31, 1999 would have been approximately $84.1 million.
 
     Cost of service increased $9.9 million, from $9.5 million for the three
months ended March 31, 1998 to $19.4 million for the three months ended March
31, 1999, primarily due to acquisitions. However, as a percentage of revenue,
cost of service decreased from 45% for the three months ended March 31, 1998 to
35% for the three months ended March 31, 1999. As Verio continues to grow, we
expect our cost of service likewise to continue to increase in absolute dollars.
However, we also expect cost of service to decrease as a percentage of total
revenue, as Verio's revenue mix shifts to higher margin Web hosting and other
enhanced value Internet services, as traffic is shifted from third party
networks to the Verio network, and as more traffic is carried by Qwest.

<PAGE>   42
 
  SALES AND MARKETING EXPENSE
 
     Sales and marketing expense consists primarily of salaries, commissions and
advertising. Sales and marketing expense decreased from 23% of total revenue for
the three months ended March 31, 1998 to 27% for the three months ended March
31, 1999, due to increases in the number of direct sales representatives,
indirect channel managers and marketing personnel, and increased national brand
advertising.
 
  GENERAL AND ADMINISTRATIVE EXPENSE
 
     General and administrative expense consists primarily of salaries and
related benefits, and includes the expenses of general management, engineering,
customer care, accounting, billing, and office space. General and administrative
expense increased $13.8 million, from $15.0 million for the three months ended
March 31, 1998 to $28.8 million for the three months ended March 31, 1999,
primarily due to acquisitions. However, as a percentage of revenue, general and
administrative expense decreased from 71% to 53%, which was the result of
efficiencies being realized by combining the operations of numerous
acquisitions. In 1998, Verio incurred significant one-time expenses in
connection with the operational consolidation and integration of its
acquisitions. These expenses included approximately $1.9 million primarily
related to severance costs in connection with the elimination of approximately
250 positions which are no longer necessary due to the efficiencies of the
national services. These terminations have begun and will continue into the
fourth quarter of 1999. The remaining liability for unpaid severance costs
totaled approximately $1.0 million at March 31, 1999.
 
     General and administrative expenses are expected to continue to increase in
absolute dollars but to decrease as a percentage of total revenue as revenue
growth continues to outpace general expenses. Verio's scalable systems limit the
number of additional personnel, and the need for additional office space to
support incremental revenue. One-time integration expenses are expected to
continue as the integration of previously acquired companies is not yet
complete, and due to the cost of integrating future acquisitions.
 
  DEPRECIATION AND AMORTIZATION
 
     Depreciation is provided over the estimated useful lives of 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. Debt issuance costs are amortized
over the life of the debt. Other intangibles consist primarily of the costs
associated with customer acquisitions and non-compete agreements and are
amortized over a three-year period. Additional acquisitions and investments are
expected to cause depreciation and goodwill amortization to increase
significantly in the future.
 
  OTHER EXPENSES
 
     Interest expense increased from $5.6 million for the three months ended
March 31, 1998 to $20.4 million for the three months ended March 31, 1999,
primarily as a result of the issuance of the March 1998 Notes and the old notes.
Interest income increased from $1.7 million for the three months ended March 31,
1998 to $4.8 million for the three months ended March 31, 1999 due to increased
cash balances resulting from the debt and equity offerings. See "-- Liquidity
and Capital Resources."

  REVENUE
 
     Total revenue increased 238% from $35.7 million for the year ended December
31, 1997 to $120.7 million for the year ended December 31, 1998. Acquisitions
completed after December 31, 1997 contributed significantly to this increase,
adding $41.4 million of the $85.0 million increase.
 
  COST OF SERVICE
 
     Cost of service increased $38.0 million, from $16.0 million for the year
ended December 31, 1997 to $54.0 million for the year ended December 31, 1998,
primarily due to acquisitions. However, as a percentage of revenue, cost of
service remained constant between the two years, at 45%.
 
  SALES AND MARKETING EXPENSE
 
     Sales and marketing expense consists primarily of salaries, commissions and
advertising. Sales and marketing expense decreased from 30% of total revenue for
the year ended December 31, 1997 to 27% for the year ended December 31, 1998,
due in part to efficiencies gained from the regionalization and nationalization
of certain sales and marketing functions. These savings were partially offset by
increased expenses related to an increase in the number of direct sales
representatives and marketing personnel, and the initiation of a national
advertising campaign.

  GENERAL AND ADMINISTRATIVE EXPENSE
 
     General and administrative expense consists primarily of salaries and
related benefits, and includes the expenses of general management, engineering,
customer care, accounting, billing, and office space. General and administrative
expense increased $46.0 million, from $38.6 million for the year ended December
31, 1997 to $84.6 million for the year ended December 31, 1998, primarily due to
acquisitions. However, as a percentage of revenue, general and administrative
expense decreased from 108% to 70%, which was the result of efficiencies being
realized by combining the operations of numerous acquisitions.
 
  OTHER EXPENSES
 
     Interest expense increased from $11.9 million for the year ended December
31, 1997 to $35.9 million for the year ended December 31, 1998, primarily as a
result of the issuance of the 1997 Notes, the March 1998 Notes and the notes.
Interest income increased from $6.1 million for the year ended December 31, 1997
to $14.6 million for the year ended December 31, 1998 due to increased cash
balances resulting from the debt and equity offerings. See "-- Liquidity and
Capital Resources."
 
     In 1998, an extraordinary loss of $10.1 million was recorded in connection
with the refinancing of $50.0 million of the 1997 Notes. See "-- Liquidity and
Capital Resources."
 
     During the year ended December 31, 1997, Verio recognized equity in losses
of affiliates of $2.0 million under the equity method of accounting for
investments owned 50% or less. Such losses were not significant for the year
ended December 31, 1998. See Note 1 to the Consolidated Financial Statements of
Verio.

</TABLE>
 
  REVENUE
 
     Total consolidated revenue was $2.4 million for the period from inception,
March 1, 1996, to December 31, 1996 -- which we refer to in this prospectus as
the 1996 Period -- compared to $35.7 million for the year ended December 31,
1997. Revenue attributable to acquisitions completed in 1996 accounted for $2.4
million or 100% of total revenue for the 1996 Period. The increase in revenue,
and in the percentage of revenue derived from enhanced services, from the 1996
Period to the year ended December 31, 1997 was primarily due to acquisitions.
Acquisitions completed after December 31, 1996 contributed significantly to this
increase, adding $22.3 million of the $33.3 million increase.
 
  COST OF SERVICE
 
     Cost of service increased $15.0 million from $1.0 million for the period
ended December 31, 1996 to $16.0 million for the year ended December 31, 1997,
primarily due to acquisitions. As a percentage of revenue, cost of service
increased from 41% to 45% primarily as a result of the buildout of the national
network and the expense associated with the Internet access contracts that
existed at acquired companies, which are in the process of being canceled as the
traffic is moved onto the national network.
 
                                       45
<PAGE>   46
 
  SALES AND MARKETING EXPENSE
 
     Sales and marketing expense consists primarily of salaries, commissions and
advertising. Sales and marketing expenses decreased from 51% of total revenue
for the year ended December 31, 1996 to 30% for the year ended December 31,
1998, due in part to efficiencies gained from the regionalization and
nationalization of certain sales and marketing functions.
 
  GENERAL AND ADMINISTRATIVE EXPENSE
 
     General and administrative expense consists primarily of salaries and
related benefits, and includes the expenses of general management, engineering,
customer care, accounting, billing, and office space. General and administrative
expense increased $32.8 million, from $5.8 million for the period ended December
31, 1996 to $38.6 million for the year ended December 31, 1998, primarily due to
acquisitions and the development of our administrative infrastructure. As a
percentage of revenue, General and administrative expense decreased from 246% to
108% primarily due to the significant increase in revenue without a commensurate
increase in general management expenses.
 
  OTHER EXPENSES
 
     During the year ended December 31, 1997, the Company recognized equity in
losses of affiliates in the amount of $2.0, representing losses of those
affiliates in excess of the equity of the common shareholders of the affiliates.
Such losses were not significant in 1996. See Note 1 to the Consolidated
Financial Statements of the Company.
 
     Interest expense increased from $0.1 million in the 1996 Period to $11.8
million for the year ended December 31, 1997 primarily as a result of the
completion of the placement of the 1997 Notes. Interest income increased from
$0.6 million for the period ended December 31, 1996 to $6.1 million for the year
ended December 31, 1997 due to increased cash balances resulting from the 1997
Notes, and the issuance of $20.0 million of Series C Preferred Stock. See
"-- Liquidity and Capital Resources."
 
  INCOME TAXES
 
     As of December 31, 1998, a net operating loss carryforward for federal
income tax purposes of approximately $133.1 million was available to offset
future federal taxable income, if any, through 2018. 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 Verio in 1996, 1997 or 1998 due to uncertainties regarding the utilization of
the loss carryforward.
 
  STOCK-BASED COMPENSATION
 
     We account for our stock-based compensation plans in accordance with
Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to
Employees, and Related Interpretations. Since inception, we have granted stock
options with exercise prices equal to the fair value of the underlying common
stock, as determined by our board of directors and based on our sales of stock
to third parties and based on quoted market prices subsequent to our initial
public offering. Accordingly, we have not recorded compensation expense related
to the granting of stock options in 1996, 1997 and through February 28, 1998.
Subsequent to February 28, 1998, and prior to the initial public offering, we
granted options to employees with exercise prices which were less than $22 per
share, which was the low end of the initial public offering filing range
immediately prior to the initial public offering. We are recording compensation
expense totaling approximately $8.2 million representing the difference between
the strike prices of the options granted and $22 per share pro rata over the
forty-eight month vesting period of the options. Compensation expense in 1998
related to these options was $1.9 million. No compensation expense was recorded
in 1996 or 1997.

  DEPRECIATION AND AMORTIZATION
 
     Depreciation and amortization increased from December 31, 1996 to December
31, 1997 primarily due to the acquisition of affiliates and capital
expenditures.
 
CASH FLOW ACTIVITY
 
     Three Months Ended March 31, 1999 -- Net cash used by operating activities
was $9.7 million during the three months ended March 31, 1999, which includes an
increase in cash of $13.1 million related to working capital items. Additional
cash used during the three months ended March 31, 1999 was primarily for
business combinations and capital expenditures, $207.6 million and $9.9 million,
respectively. Of the $207.6 million used for business combinations, $176.0
million was for the acquisition of Hiway. Sources of cash included approximately
$2.3 million from the exercise of options.
 
     Three Months Ended March 31, 1998 -- Net cash used by operating activities
was $14.8 million during the three months ended March 31, 1998, which includes a
decrease in cash of $2.6 million related to working capital items. Sources of
cash included approximately $175.0 million from the March 1998 Notes of which
$54.5 million was used to repurchase $50.0 million principal amount of the 1997
Notes. Other cash used during the three months ended March 31, 1998 was
primarily for business combinations and capital expenditures, $18.8 million and
$3.8 million, respectively.
 
     Fiscal 1998 -- Net cash used by operating activities was $64.2 million
during the year ended December 31, 1998, which includes an increase in cash of
$4.5 million related to working capital items. Sources of cash included
approximately $120.8 million net proceeds from our initial public offering,
$100.0 million from the sale of common stock to an affiliate of Nippon Telegraph
and Telephone Corporation, $175.0 million from the March 1998 Notes and $400.0
million from the old notes. Cash used during 1998 was primarily for business
combinations and capital expenditures, $151.1 million and $23.1 million,
respectively. Verio also used approximately $54.5 million of the proceeds from
the March 1998 Notes to repurchase $50.0 million principal amount of the 1997
Notes.
 
     Fiscal 1997 -- Net cash used by operating activities was $35.3 million
during the year ended December 31, 1997, which includes an increase in cash of
$0.1 million related to working capital items. Sources of cash included
approximately $20.0 million from the sale of 2.5 million shares of Series C
preferred stock and $150.0 million from the issuance of the 1997 Notes. Cash
used during 1997 was primarily for business combinations and capital
expenditures, $64.0 million and $14.5 million, respectively. Additionally,
approximately $46.6 million was invested in a restricted cash account to service
interest payments on the 1997 Notes.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Our business strategy has required and is expected to continue to require
substantial capital to fund acquisitions and investments, capital expenditures,
and operating losses.
 
     In 1996, we raised approximately $78.1 million from the sale of Series A
and B preferred stock and approximately $1.1 million from the sale of common
stock.
 
     In 1997, we raised approximately $20.0 million from the sale of Series C
preferred stock, and issued 680,000 shares of Series D-1 preferred stock in
connection with an acquisition.
 
     On June 24, 1997, we completed the placement of $150.0 million principal
amount of the 1997 Notes and attached warrants. One hundred and fifty thousand
units were issued, each consisting of $1,000 principal amount of Notes and eight
warrants. The 1997 Notes mature on June 15, 2004 and interest, at the annual
rate of 13 1/2%, is payable semi-annually in arrears on June 15 and December 15
of each year. Each warrant entitles the holder thereof to purchase 1.76 shares
of Verio'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 1997 Notes were separated on
December 15, 1997. Concurrent with the completion of the sale of the 1997 Notes,
we were required to deposit funds into an escrow account in an amount that
together with interest is sufficient to fund the first five interest payments.
The 1997 Notes are redeemable at our option commencing June 15, 2002. The 1997
Notes are
 
                                       47
<PAGE>   48
 
senior unsecured obligations ranking equally in right of payment with all
existing and future unsecured and senior indebtedness.
 
     On March 25, 1998, we completed the placement of $175.0 million principal
amount of the March 1998 Notes. The March 1998 Notes are senior unsecured
obligations ranking equally in right of payment with all existing and future
unsecured and senior indebtedness, and mature on April 1, 2005. Interest on the
March 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
March 1998 Notes are redeemable at our option commencing April 1, 2002. Verio
used approximately $54.5 million of the proceeds from the March 1998 Notes to
effect the refinancing. Upon consummation of the sale of the March 1998 Notes
and the refinancing, $13.3 million of escrowed interest funds were released to
us.
 
     At various times during the first four months of 1998, we issued 1,534,513
additional shares of Series D-1 preferred stock in connection with the purchases
of substantially all the remaining unowned interests in our subsidiaries and
affiliates.
 
     On April 6, 1998, we entered into a $57.5 million revolving credit facility
with a group of commercial lending institutions secured by the stock of our
subsidiaries and the Qwest capacity agreement. The credit facility was increased
to $70.0 million on September 25, 1998. The credit facility requires no payments
of principal until its maturity on December 31, 1999. The terms of the credit
facility provide for borrowings at a margin of 2% above the London Interbank
Offer Rate. There is a commitment fee of  1/2% per annum on the undrawn amount
of the credit facility and a one-time fee of  1/2% on any amounts drawn. The
last $3.0 million of the credit facility can only be drawn for the payment of
interest. We have made no borrowings under the credit facility.
 
     The credit facility contains a number of other restrictions, including
limitations on our ability to:
 
     - engage in businesses other than the Internet service business;
 
     - place liens on our assets; and
 
     - pay dividends.
 
     In addition, under the credit facility, our indebtedness, less cash, may
not exceed 2.35 times our annualized pro forma revenue for the most recent
quarter. We currently have the ability to borrow the full $70.0 million
commitment. We are required to pay back any amounts borrowed under the credit
facility with the proceeds of new indebtedness, certain asset sales, free cash
flow in excess of $5.0 million in any quarter, or the net proceeds from
insurance claims.
 
     In May 1998, we completed our initial public offering, selling an aggregate
of 5,735,000 shares of common stock, including the partial exercise of the
over-allotment option by the underwriters in the initial public offering, for
net proceeds of approximately $120.8 million, after deducting underwriting
discounts, commissions and expenses. Concurrently with our initial public
offering, we completed the sale of 4,493,877 shares of common stock to an
affiliate of Nippon Telegraph and Telephone Corporation for net proceeds of
approximately $100.0 million.
 
     On November 25, 1998, we sold $400.0 million principal amount of the old
notes, for net proceeds of approximately $389.0 million. Interest at the annual
rate of 11 1/4%, is payable semi-annually in arrears on June 1 and December 1 of
each year, commencing June 1, 1999. We have the option of redeeming the notes
starting from December 1, 2003.
 
     The 1997 Notes, the March 1998 Notes and the notes contain terms, other
than the rate of interest, that are substantially similar. The terms of the
indentures governing these notes impose significant limitations on our ability
to incur additional indebtedness unless we have issued additional equity, or if
our Consolidated Pro Forma Interest Coverage Ratio, as defined in the
indentures, 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, and if the ratio of our total debt to earnings
before interest, taxes, depreciation and amortization is not higher than 6:1.
 
                                       48
<PAGE>   49
 
     The indentures contain a number of other restrictions, including, among
others, limitations on our ability to:
 
     - engage or make investments in businesses other than the Internet service
       business;
 
     - place liens on or dispose of our assets; and
 
     - pay dividends.
 
     If a change of control with respect to Verio occurs, we are required to
make an offer to purchase all the notes then outstanding at a price equal to
101% of the respective principal amount of the notes, plus accrued and unpaid
interest. We are in compliance with the provisions of all of our material debt
agreements.
 
     As of March 31, 1999, we had approximately $354.0 million in cash and cash
equivalents and short-term investments, including $15.4 million of restricted
cash. Our business plan currently anticipates investments of approximately
$140.0 million over the next 12 months for capital expenditures, acquisitions
completed since December 31,1998, operating losses and working capital.
 
     Our Company is highly leveraged and has significant debt service
requirements. At March 31, 1999 our long-term liabilities were $690.3 million,
and the annual interest expense associated with the 1997 Notes, the March 1998
Notes and the notes is approximately $76.7 million. The interest expense and
principal repayment obligations associated with our debt could have a
significant effect on our future operations. See "Risk Factors -- We have
substantial debt which may impact our future operations and affect our ability
to meet our debt obligations."
 
     Since we achieved 100% ownership of substantially all of our subsidiaries
and affiliates in the second quarter of 1998, we have focused considerable
effort on, and incurred significant expense in connection with, the integration
of our operations and management. We expect to continue to incur integration
costs related to our network, customer care, billing and financial systems.
While we anticipate that these expenses will continue to be significant, we also
expect to derive significant long-term benefits as a result of lower incremental
costs for local telecommunications expense, Internet access expense, and general
and administrative expenses as our revenues increase.
 
     Our anticipated expenditures are inherently uncertain and will vary widely
based on many factors including operating performance and working capital
requirements, the cost of additional acquisitions and investments, the
requirements for capital equipment to operate our business, and our ability to
raise additional funds. Accordingly, we may need significant amounts of cash in
excess of our plan, and no assurance can be given as to the actual amounts of
our future expenditures. We are constantly evaluating potential acquisition and
other investment opportunities which could significantly affect our cash needs.
We intend to use a significant portion of our cash for acquisitions, and will
have to increase revenue without a commensurate increase in costs to generate
sufficient cash to enable us to meet our debt service obligations. There can be
no assurance that we will have sufficient financial resources if operating
losses continue to increase or additional acquisition or other investment
opportunities become available.
 
     We expect to meet our capital needs with cash on hand, proceeds from the
sale, or issuance of capital stock, the credit facility, lease financing, and
additional debt. We regularly examine financing alternatives based on prevailing
market conditions, and expect to access the capital markets from time to time
based on our current and anticipated cash needs and market opportunities. In the
near term, we intend to use our excess cash. Over the longer term, we will be
dependent on increased operating cash flow, and, to the extent cash flow is not
sufficient, the availability of additional financing, to meet our debt service
obligations. As an ongoing matter, we evaluate the potential sources of capital
that may be available to us, including public and private sales of equity, the
issuance of debt securities, bank financing, and other sources, taking into
account market conditions, available terms, the current trading price of our
stock, and other factors. Insufficient funding may require us to delay or
abandon some of our planned future expansion or expenditures, which could have a
material adverse effect on our growth and ability to realize economies of scale.
In addition, our operating flexibility with respect to certain business
activities is limited by covenants associated with our
 
                                       49
<PAGE>   50
 
indebtedness. There can be no assurance that such covenants will not adversely
affect our ability to finance our future operations or capital needs or to
engage in business activities that may be in our interest.
 
NEW ACCOUNTING STANDARDS
 
     During 1997, the Financial Accounting Standards Board issued Statements of
Financial Accounting No. 130, Reporting Comprehensive Income, No. 131,
Disclosures About Segments of an Enterprise and Related Information and No. 132,
Employers' Disclosures about Pensions and Other Postretirement Benefits. During
1998, the Financial Accounting Standards Board issued Statements of Financial
Accounting No. 134, Accounting for Mortgage-Backed Securities Retained after the
Securitization of Mortgage Loans Held for Sale by a Mortgage Banking Enterprise
and the American Institute of Certified Public Accountants issued Statement of
Position No. 98-5, Reporting on the Costs of Start-up Activities. The adoption
of these pronouncements did not and is not expected to have a significant effect
on Verio's financial position, results of operations or financial reporting.
 
     In June 1998, the Financial Accounting Standards Board issued Statements of
Financial Accounting No. 133, Accounting for Derivative Instruments and Hedging
Activities, which is effective for all fiscal quarters of fiscal years beginning
after June 15, 1999. This statement establishes accounting and reporting
standards for derivative instruments, including some derivative instruments
embedded in other contracts, and for hedging securities. To the extent we begin
to enter into such transactions in the future, we will adopt the statement's
disclosure requirements in the financial statements for the year ending December
31, 2000.
 
THE YEAR 2000 ISSUE
 
     The year 2000 issue results from computer programs and systems using only
two digits instead of four to identify the year. Systems that do not properly
recognize this date could generate wrong data or fail. The year 2000 issue is
widespread and complex, as virtually every company's computer operations
potentially could be affected in some way.
 
     We rely upon computer systems, software applications, hardware and other
circuitry which may contain date-sensitive technology in our operations and
administrative support systems. Most of these technologies are
standard-purchased systems that may or may not have been customized for our own
particular applications while other technologies were internally developed. We
also rely upon various vendors and suppliers including telecommunications
providers with which we have interconnection, peering and resale agreements.
 
     Many of our business systems are being replaced as part of our efforts to
integrate our acquisitions. As we evaluate new systems for purchase, we assess
whether they are year 2000 compliant. We are currently engaged in a phased
process utilizing outside consultants and designated employees to evaluate our
internal status with respect to the year 2000 issue. The costs and expenses of
these outside consultants and employees have not been material. To date, we have
not discovered any year 2000 issues that would adversely affect us. We cannot
assure that all year 2000 issues were discovered or that we will not discover
additional year 2000 issues that could adversely affect us.
 
     In our first phase, completed in the fourth quarter of 1998, we conducted
an assessment of our national systems in Denver, Colorado, Dallas, Texas and
regional networks and systems in our east operating region, including both
information technology systems and non-information technology systems such as
hardware containing embedded technology, for year 2000 compliance. The network
systems of our operating regions have similar technology. No significant issues
have been identified. If issues are uncovered in the future, that knowledge will
be directly applied to other operating regions.
 
     Prior to our acquisition of Hiway, Hiway hired outside consultants to
evaluate their systems for year 2000 compliance. Though issues were noted in the
internally developed provisioning systems, none were evaluated as material and
remediation activities are in progress.
 
     We expect to complete phase two of the process during the second quarter of
1999. It will involve a more detailed and broader assessment of our systems'
degree of year 2000 compliance, covering all operating
 
                                       50
<PAGE>   51
 
regions and entities. Specific risk assessments and contingency planning will be
the primary focus of this phase. We will also develop a fallback plan in the
event any critical systems remain non-compliant by January 1, 2000. As part of
phase two, we will attempt to quantify the impact, if any, of the failure to
complete any necessary corrective action. We cannot currently estimate the
magnitude of such impact.
 
     To date, the costs incurred with respect to phase two have not been
material. Future costs are difficult to estimate; however, we do not currently
anticipate that such costs will be material.
 
     Phase three of our year 2000 plan will include performing end to end
testing of our supplied services under various scenarios to verify expected
performance of the network under various year 2000 date failure modes. The
purpose of the testing will be to ensure continuity of service to customers, not
specific elemental component compliance status. This phase is expected to be
final verification of any required updates to Verio's systems and should be
completed in the third quarter of 1999.
 
     We have begun to survey, among others, critical vendors, suppliers and
financial institutions for year 2000 compliance. We are in the process of
evaluating the year 2000 preparedness of our telecommunications providers, on
which we rely for the network services crucial to our business. In order to
reduce any adverse impact, we maintain diverse providers for such network
services. However, failure of any one provider may have a material impact on
Verio's operations. We expect to complete this survey in the second quarter of
1999. At this time we cannot estimate the effect, if any, that non-compliant
systems at these entities could have on us, however, it is possible that the
impact will be material.

                                    BUSINESS
 
BACKGROUND OF OUR BUSINESS
 
     Internet access and enhanced value Internet services, including Web hosting
and electronic commerce services, represent two of the fastest growing segments
of the telecommunications services market. The availability of Internet access,
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 Internet users.
 
     In order to capitalize on the power of the Internet, businesses must adopt
one or both of the fundamental Internet service platforms: Internet access and
an Internet Web site. Internet access provides a company with the
telecommunications circuits necessary to allow a company to connect to the
Internet, communicate with employees, customers and suppliers and other Internet
users, transfer electronic mail, and access the wealth of information available
over the Internet. A Web site provides a company with a corporate presence on
the Internet. This computer-based site allows a company to post information
about itself that is easily accessible to all Internet users. Businesses are
increasingly adding a variety of enhanced services and applications to their
basic Internet access and Web site platforms, in order to more fully capitalize
on the power of the Internet. These services and applications allow them to more
efficiently communicate company information, expand and enhance their
distribution channels, increase productivity through back-office automation and
reduce costs.
 
     Verio expects this trend to continue as high capacity Internet data
transmission, high functionality enhanced value Internet services continue to be
developed, improve and proliferate and as Internet usage continues to expand.
For example, once a company has basic Internet access, by then connecting each
of the company's office locations and providing them with security tools, such
as data encryption, the company can implement a secure Internet communication
links permitting its employees, vendors, customers, and other designated
individuals to engage in secure, private communications over the Internet.
Further, by provisioning its Web site with enhanced application tools, the
company can automate business processes such as sales order entry, shipping,
inventory management and customer service from this site. When conducting
electronic commerce over a Web site, a company typically will add security,
shopping cart, and payment processing capabilities to its basic Web site.
 
     Industry analysts have reported that small and medium sized businesses
represent a potential market of over seven million customers in the U.S. Verio
has specifically targeted the small and medium sized business market for the
provision of our Internet services because:
 
     - A small percentage of this market currently utilizes the Internet, but
       that number is increasing rapidly and is expected to be one of the
       fastest growing segments of the Internet industry.
 
     - These businesses have rapidly expanding Internet needs, as they and their
       customers look more and more to the Internet for information, as a
       standard mode of communication, and to conduct business in increasingly
       sophisticated and cost-effective ways.
 
     - These companies often look to an Internet service provider to fulfill
       these needs, because they typically lack the technology expertise,
       information technology resources, capital, personnel, or ability to bear
       the time-to-market and operational risks required to install, maintain
       and monitor their own Web servers and Internet access.
 
     - In selecting an Internet service provider, these businesses often prefer
       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.
 
     - Businesses that have outsourced their Internet requirements tend to
       become quite dependent on their Internet provider and tend to change
       Internet providers relatively infrequently.
 
                                       52
<PAGE>   53
 
     The Internet service provider market is segmented into large national or
multinational providers such as Verio, which typically are full service
providers, and regional and local providers which generally offer a smaller
range of services and products and lack the ability to meet all the needs of a
business customer. Full service Internet providers also typically resell
capacity on their network to regional and local providers, who rely on the
larger providers for Internet access. The largest full service providers, like
Verio, have what are referred to as "tier one" networks, which exchange Internet
traffic cost free at multiple public peering points known as network access
points, as well as through private peering arrangements. As the number of
Internet service providers has grown, the requirements to become a tier one
network have increased, resulting in a higher barrier to achieving this tier one
provider status.
 
OUR BUSINESS STRATEGY
 
     Our business strategy of combining national scale with local presence was
specifically developed to serve the needs of the small and medium sized business
market. In formulating its business strategy, Verio concluded that the large,
national Internet service providers lacked the local presence to provide
customized hands-on support, while the smaller, local Internet service providers
did not have the requisite scale and resources to provide a full range of
services at an acceptable quality and pricing levels. We believe that Verio has
a competitive advantage in serving these business customers because we have
combined the technical expertise and hands-on support, provided through our
local sales and engineering personnel, with the quality and economic efficiency
of our national network, operational infrastructure and financial strength.
 
     Verio's goal is to be the premier, full-service provider of Internet
services to small and medium sized businesses. The key elements of our strategy
in accomplishing this goal are:
 
     - Build Scale, Market Presence and Service Offerings through Acquisitions
       and Strategic Relationships. We have rapidly established a global
       presence and expanded our customer base by acquiring established Internet
       access and enhanced service providers with a business customer focus. We
       intend to continue to expand our market presence, strengthen our Internet
       access and Web hosting core service platforms, and add additional
       enhanced value service capabilities, both through further acquisitions
       and strategic relationships with key product and service partners. Given
       our large customer base, broad distribution channels and established core
       service strengths in Internet access and Web hosting, we believe that
       Verio is an attractive potential acquirer or strategic partner for other
       related enhanced value product and service companies.
 
     - Integrate Operations and Leverage National Infrastructure to Reduce Costs
       and Improve Quality. We continue to improve our efficiency, service
       reliability, quality and scalability by:
 
         (1) integrating the Internet operations we acquire onto core national
      service platforms for Internet access and Web hosting;
 
         (2) focusing regional operations on sales, distribution and customer
      support; and
 
         (3) leveraging a common set of national systems and support services.
 
      We integrate the local networks we acquire and connect them to Verio's
      tier one national backbone, provide them with network management and
      monitoring services from our network operations center, consolidate point
      of presence facilities, aggregate traffic on higher capacity, lower cost
      telecommunication circuits, consolidate engineering and network operations
      staffs, increase network redundancy and ensure consistency of network
      operations. Similarly, we integrate our Web hosting operations onto common
      national platforms with regional data centers connected to Verio's tier
      one national backbone and monitored by Verio's network operations center.
      Through this integration, we capture economies of scale, drive operational
      efficiency, ensure operational control and improve the quality,
      consistency and scalability of our services. We have leveraged our scale
      to negotiate advantageous national volume purchasing agreements with key
      vendors such as Cisco, Qwest and Raptor.
 
                                       53
<PAGE>   54
 
     - Build Brand Recognition, Expand Distribution Channels and Leverage Local
       Support to Drive Growth. We believe that brand recognition will be an
       increasingly important decision factor among small and medium sized
       businesses in choosing an Internet service provider. In conjunction with
       the integration of our acquired providers, we have re-branded our
       consolidated regional operations under the Verio name. We are building
       national Verio brand recognition by aggressively marketing our full range
       of services through a national advertising campaign using traditional
       media, on-line campaigns and trade shows, strategic co-marketing
       relationships, and a coordinated public relations program. Most recently,
       in March 1999, we entered into a strategic relationship with America
       Online, Inc., which we expect will substantially expand Verio's national
       brand name recognition. Under this agreement, for a three-year period,
       Verio has acquired exclusive rights to market its Web hosting and
       business-focused electronic commerce services on America Online's four
       key on-line media properties in the U.S.
 
      We currently have over 200 local direct sales executives, over 300 local
      engineers and customer support technicians, and over 4,000 resellers and
      referral partners. We expect to continue to expand this sales and
      distribution force and to increase its effectiveness through national
      training, sales support, advertising and marketing programs. We also
      market our services nationally through direct mail, telemarketing and
      on-line marketing campaigns. In addition, Verio has expanded the marketing
      of its services through original equipment manufacturer type relationships
      with major telecommunications carriers, such as Nippon Telegraph and
      Telephone Corporation, who can offer Verio's services on a private-label
      or co-branded basis to their customer base. NTT America, an affiliate of
      Nippon Telegraph and Telephone Corporation, has recently launched its
      branded Arcstar Internet service in the U.S., and will resell the full
      range of Verio services under this brand.
 
     - Develop and Offer Enhanced Value Products and Services to Increase
       Revenues. While basic Internet access and Web hosting constitute the
       predominant services offered by Verio today, small and medium sized
       businesses are increasingly looking for enhanced value products and
       services that allow them to further leverage the power of the Internet to
       expand markets, increase productivity and reduce costs. We believe that
       our large existing customer base and strong, balanced position in both
       the Internet access and Web hosting service platforms give us a
       competitive edge in offering high-margin, enhanced value Internet
       services and bundled packages to meet the evolving needs of our current
       and future customers. As a result, we believe that we will be able to
       derive increasing revenue from these customers and increase profitability
       by selling an expanding array of enhanced value Internet services, as
       well as better performing Web sites and additional Internet data
       transmission capacity capabilities to support these services. Examples of
       these Web-based enhanced value Internet services include:
 
        - electronic commerce;
 
        - Web-based faxing and email;
 
        - unified messaging -- which is the aggregation of various messaging
          formats, such as fax, voice, email, into a single point of contact;
 
        - office and business process automation capabilities;
 
        - audio and video applications;
 
        - automated Web site development tools and templates; and
 
        - redundant "hot" sites -- which are multiple presence Web site
          hosting -- across multiple national and international data centers.
 
      We currently offer high capacity data transmission digital subscriber line
      circuits as an access option through the relationship which we commenced
      with NorthPoint Communications in early 1999 and plan to offer additional
      alternative Internet access options, as well as intranets and extranets
      incorporating both Internet access and Web-hosting capabilities. Intranets
      are corporate/organizational networks that rely on Internet-based
      technologies to provide secure links between corporate offices and secure
      access to company data. Extranets expand the network to selected business
      partners through secured links on the Internet. We also offer enhanced
      value Internet security capabilities and
 
                                       54
<PAGE>   55
 
      professional consulting services to support a variety of methods or
      processes to resolve our customers' Internet problems. We expect to
      provide these further enhanced value Internet services through a
      combination of internal development and packaging, acquisitions and new
      relationships with Internet hardware, software and service companies.
 
THE VERIO ORGANIZATION
 
     Verio conducts its operations with both a national and regional approach.
Initially, we pursued a regional acquisition strategy, acquiring independent,
locally based Internet service providers to establish critical mass and a
widespread market presence in the top metropolitan statistical areas across the
U.S., which we then consolidated into regional operations. In order to provide
services such as Web hosting on a national basis, we have also sought to acquire
enhanced service providers with extensive national operations. Our acquisitions
of iServer, TABNet and Hiway established Verio as the largest Web hosting
company in the world based on the number of domain names hosted, and
significantly increased our technical, marketing and operational strength.
 
     As of March 31, 1999, we had acquired over 47 Internet service providers,
including the funding of start-up operations in the Midwest and Rocky Mountain
regions. We continue to consolidate the ownership and management of these
providers, and to integrate their network operations, customer support,
marketing efforts, financial and accounting systems, and other back-office
functions onto our national systems, in order to maximize operating synergies
and efficiencies. We are now focusing our efforts on expanding our market
presence and our strength in our Internet access and Web hosting core service
platforms, and adding enhanced value service capabilities. We continue to
evaluate additional potential acquisition and strategic partner candidates.
 
PRODUCTS AND SERVICES
 
     Verio currently offers a comprehensive range of business Internet services,
including its core Internet access and Web hosting services, as well as a
variety of related enhanced value products and services that enhance these core
offerings. Verio offers a core suite of products and services nationally, with
additional specific products offered in designated markets based on factors such
as unique needs within a particular market and local telecommunications tariffs.
As its customers needs evolve, Verio intends to continue to develop a broad
range of enhanced value products and services independently, through
acquisition, and through strategic relationships with key vendors.
 
     Internet Access Services. Verio offers a variety of core Internet access
solutions, providing basic connectivity to the Internet, as well as a suite of
enhanced value products and services enabling our customers to expand their
basic Internet connectivity capability. For example, these additional services
allow them to send and receive e-mail, or to engage in private, secure data
transmissions between remote offices. These products are offered in bundled and
unbundled packages.
 
     Our core Internet access services currently include:
 
     - Basic Internet access: Our basic Internet access service currently
       includes dial-up access at speeds ranging from 28.8 to 56 kilobytes per
       second, integrated services digital network providing 64 to 128 kilobytes
       per second access, digital subscriber line access providing 144 kilobytes
       per second to over 1 megabytes per second, and frame relay and leased
       line connectivity at speeds ranging from 28.8 kilobytes per second to 155
       megabytes per second.
 
     - Hardware products: As we provision access services, we provide necessary
       hardware including routers, servers and other products as needed by the
       particular customer. Our national purchasing and leasing relationships
       with a variety of equipment partners provide improved hardware pricing,
       lower cost leasing arrangements and bundled service offerings.
 
     - Software products: Our software products include browsers, set up disks
       and other solutions that permit customers to more effectively and easily
       navigate and utilize the Internet.
 
                                       55
<PAGE>   56
 
     - Configuration services: Our configuration solutions encompass services
       such as domain name server support, supplying telecommunication circuits,
       Internet protocol address space assignment, router set-up, electronic
       mail configuration, router security configuration and other similar
       set-up services.
 
     Our enhanced value Internet access services currently include:
 
     - E-mail: We provide e-mail services that permit customers to send and
       receive electronic mail messages. These services are offered either using
       the customer's domain name or though Verio's generic domain name. In
       order to provide our customers with the latest developments in e-mail and
       messaging services, we are in the process of converting our over 800,000
       e-mail boxes to a centralized, state of the art e-mail system supported
       by technology licensed to us by Netscape Communications Corporation.
 
     - Secure Internet Communication Links: Many companies today have private
       data communication networks to transfer data between office locations.
       These are often referred to as wide area networks, and tend to be built
       on expensive leased telecommunication lines. The Internet offers
       companies a cost-effective alternative to wide area networks through
       secure Internet communication links, which are meant to provide secure
       transmission of private Internet protocol traffic through the Internet.
       Additionally, many companies require that their employees have remote
       access to these private networks from home or while traveling, which
       these secure Internet communication links can also provide. These
       products are available in hardware, software, and firewall -- software or
       hardware that prevents unauthorized access to a computer from outside the
       immediate internal network -- formats. These products, often in
       combination with a Web site, are also the basis for offering intranet and
       extranet services. Increasingly, companies are finding that intranets and
       extranets can enhance corporate productivity more easily and less
       expensively than proprietary systems. We currently offer our customers a
       number of secure Internet communication link solutions, including
       Raptor's Firewall, IRE's SafeNet(TM), and Watchguard's Firebox II(TM),
       and we continue to evaluate additional products to meet our customers'
       needs in this area.
 
     - Security: Security solutions are a vital component for most businesses
       connected to the Internet, as they are designed to prevent unauthorized
       access to computers from outside the immediate internal network and
       provide for secure Internet communication transmission. These solutions
       include:
 
      (1) firewalls -- software or hardware that prevents unauthorized access to
          a computer from outside the immediate internal network;
 
      (2) packet filter -- a method of screening, eliminating and prioritizing
          packets of data to prevent unauthorized access to a network;
 
      (3) proxy servers -- a server designed to intercept inbound data and
          process it prior to use on an internal network; and
 
      (4) encryption -- manipulation of data into a secret format to prevent
          anyone but the intended recipient from recognizing the data
          accurately.
 
      These solutions give the customer an ability to prevent intruders from
      accessing its corporate network, authenticate the identity of users
      attempting to gain access to the customer's local area network or Web
      site, and provide secured transmission of company data through the
      Internet. We currently offer a comprehensive set of such security products
      from Raptor, including the sophisticated Eagle Firewall(TM). Additionally,
      we offer a "managed" security solution that provides ongoing detection and
      prevention of intrusions. We plan to expand our security product line with
      new solutions that simplify, reduce cost, or offer greater functionality
      as they become commercially available. We recently selected Seattle,
      Washington-based WatchGuard Technologies, Inc., a leading provider of
      Internet security solutions, as a supplier for our managed security
      services for businesses. Our managed security services solutions are
      designed to protect small and medium sized businesses from electronic
      intruders and dynamic on-line risks. Based on WatchGuard's LiveSecurity
      for MSS(TM) security system, our
 
                                       56
<PAGE>   57
 
      managed security services safeguard businesses by monitoring their
      security around the clock, reducing the demands on internal
      administrators.
 
     Businesses are increasingly seeking to use the Internet for an expanding
array of telecommunication services. We plan to likewise expand our ability to
serve these more sophisticated Internet access needs by deploying additional
enhanced value Internet access-based services as they become commercially
available. Such products that are currently under development include Internet
protocol telephony, which permits users to make voice calls on the Internet,
Internet faxing, Internet audio and video conferencing solutions. Additionally,
we are participating in trials for the deployment of new access technologies,
such as wireless access.
 
     Web Hosting Services. A Web site provides a company with a tangible
identity and interactive presence on the Internet. This computer-based site
allows a company to post information about itself that is easily accessible to
all Internet users. Web sites are also the basis for providing electronic
commerce, where a company can advertise and sell its products and services.
Verio offers a comprehensive range of core Web site hosting products, as well as
a growing suite of enhanced web site hosting products including electronic
commerce solutions. Generally, our customers elect to outsource to us the
hardware and software provisioning that is necessary to host a Web site, where
we can provide these services from our highly reliable data center environments.
However, for our customers with the resources and desire to provide their own
computer equipment and software, we offer specialized facility lease resources,
providing them with space to house their equipment in one of our secure,
controlled facilities. Our Web site hosting products currently range in price
from $14.95 per month to tens of thousands of dollars per month.
 
     Our core Web hosting services currently include:
 
     - Shared Server Web Hosting: Shared servers allow Web hosting of multiple
       accounts or multiple Web sites on a single computer system. Verio offers
       a series of shared server Web hosting plans that allow individuals and
       businesses to establish a sophisticated presence on the Internet at a
       reasonable cost, leveraging Verio's expertise and equipment to deploy an
       effective Web site. Our basic, standardized Web hosting option offers
       6,000 megabytes of data transfer per month and 30 megabytes of disk
       storage on computers that are owned and maintained by Verio in one of its
       data centers and monitored seven days a week, twenty-four hours a day.
       This service level allows customers to store hyper text markup
       language -- the language used to create Web pages with links, graphics,
       video and sound files on Verio's server. This basic shared server plan
       generally satisfies customers' basic speed of Internet data transmission
       and disk storage requirements. A majority of our current shared server
       Web hosting customers use the entry-level service. In order to allow
       customers to use their Web site as an effective interface for
       communication, we provide additional services bundled into our shared
       server hosting plans. For example, our shared server customers are
       provided various Web-based electronic mail options, support for Microsoft
       FrontPage(TM) extensions and a variety of unique Web site development
       tools as part of the basic Web hosting account. The higher priced shared
       server Web hosting offerings, including the proprietary Virtual Server
       technology, provide customers additional enhanced value Internet
       services, functionality and resources. Each successive pricing tier
       allocates the customer more disk storage and increases the monthly data
       transfer limit. In addition, the more advanced plans offer Real
       Audio(TM), Real Video(TM) and mSQL(TM) database support and support for
       electronic commerce-enabled Web sites.
 
     - Shared Server Support Tools: We have implemented a variety of tools to
       allow our shared server customers to manage and enhance their sites more
       effectively and update their Web sites remotely. Typically, the Web
       hosting plans feature detailed Web statistics and access to raw log
       files, giving customers the ability to track the performance and evaluate
       the effectiveness of their Web sites. Higher tier plans offer customers
       their own configuration files, point of presence server and simple mail
       transfer protocol gateway. In addition, we provide a number of popular
       custom gateway interface scripts that allow customers to put into use hit
       counters, guest books, mail forms and other useful graphics easily, and
       also support custom gateway interface scripts that enable customers to
       build additional functionality into their Web sites. We offer numerous
       tools which allow a customer to have
                                       57
<PAGE>   58
 
increased control over managing its Web site, allowing them to change passwords,
set electronic mail forwarding options, view Web site statistics and check
account and billing information. Additionally, all shared servers have regular
      back-up procedures to protect customer files.
 
     - Dedicated Server Web Hosting: Dedicated servers allow Web hosting of a
       single Web site on one computer system. Verio offers dedicated server Web
       hosting solutions for larger customers that prefer not to host their Web
       sites on a shared server. This solution, which provides substantially
       more server and network resources than those available from a shared
       server, gives customers the ability to run complex applications without
       the additional information technology administration costs and
       considerations that customers would experience if they managed their own
       servers and Web sites internally. The dedicated server Web hosting
       solutions provide the customer with an NT or UNIX-based server that is
       owned and maintained by Verio in one of its data centers and monitored
       seven days a week, twenty-four hours a day. We maintain spare equipment
       and back up data regularly. We offer the dedicated server service at
       various prices depending upon the specific hardware configuration, level
       of service and data transfer rates required by the customer.
 
     - Specialized Facility Lease Services: Verio offers specialized facility
       leases for customers that require the resources of a dedicated server,
       prefer to retain physical access to and ownership of their server, and
       have the expertise to maintain the Web site and the server. Our
       specialized facility leases offer customers a secure location,
       environmental control, monitoring and a high-speed connection to the
       Internet. These facilities typically are designed to provide an
       uninterruptible power source, a back-up diesel generator, climate control
       and monitoring seven days a week, twenty-four hours a day.
 
     - Domain Name Registration: Each business or individual that desires a
       personalized Web address must first reserve a domain name (such as
       www.yourcompany.com). As more individuals and businesses establish a Web
       presence, desirable domain names, like trade or service marks, become
       more difficult to secure. We are the world leader in providing this
       important service, registering more domain names (.com, .net, .org) with
       Network Solutions -- currently the single designated domain name
       registrar -- than any other company. For a one-time fee, we will register
       and maintain a domain name for two years or until the customer decides to
       use the domain name to host an active Web site. We believe that offering
       this service provides us a marketing advantage when these domain name
       registration customers then select a Web hosting provider. We actively
       telemarket to new customers registering a domain name and have a high
       conversion rate of these customers to our recurring revenue Web hosting
       services. We have recently been designated by the Internet Corporation
       for Assigned Names and Numbers as an official registrar of Internet
       domain names, which is expected to take effect in July 1999. Because
       domain name registration is the primary entry point for developing a Web
       presence, we believe that becoming a direct registrar of domain names
       represents an important customer acquisition channel for us.
 
     The enhanced value Web hosting services that we currently provide include:
 
     - Electronic Commerce Solutions: Electronic commerce provides businesses
       the ability to sell products and services on the Internet. The electronic
       commerce capability can be added to an existing Web site or it can be the
       basis for a Web site, starting with the customer's product catalog. The
       principle basic components of an electronic commerce enabled Web site
       include:
 
        - a hosted Web site;
 
        - a catalog of the products to be sold from the site, including prices
          and inventory -- a secure means of accepting orders from customers
          visiting the site;
 
        - a secure means of accepting payment for those orders -- a means of
          calculating the appropriate tax and shipping costs attributable to the
          order;
 
        - transaction reporting capability; and
 
        - a means of reconciling these transactions with the company's
          accounting records.

      Verio currently offers a variety of electronic commerce packages. Our
      entry level "CyberStand" product is designed for a merchant with a very
      limited number of products to sell that does not require real time payment
      clearing. Another more advanced product is the "eVendor" product which
      allows a substantially greater number of products to be offered in the
      catalog, but still relies on manual payment processing. The "MarketPlace"
      product is for the more sophisticated merchant who desires an unlimited
      number of products to be sold and requires secure, on-line real time
      payment settlement. We have relationships with numerous providers of the
      various components of our electronic commerce solutions, including tools
      for catalog and site creation, merchant accounts, digital certificates,
      transaction processing and numerous additional components that are
      required to build a completely commerce enabled Web site. Most recently,
      Verio entered into an agreement with iMall, Inc., a leading provider of
      fully integrated, "one-stop" electronic commerce solutions, and a related
      agreement with First Data Merchant Services Corporation, one of the
      nation's leading providers of Internet payment processing solutions, in
      order to offer complete electronic commerce services to businesses. Verio
      will offer the iMall/First Data Merchant Services solution as Verio's
      preferred electronic commerce service through verio.com, select other Web
      sites, and its direct marketing sales forces, as well as marketing the
      solution to its existing Web hosting customers. These VerioStore(TM) plans
      offer small and medium-sized businesses a complete, affordable and easy
      way to set up virtual storefronts on the Web. Based on the comprehensive
      electronic commerce solution jointly developed by iMall and First Data
      Merchant Services, VerioStore will include on-line product catalogs, a
      search engine, cash register, shopping cart, shipping and sales tax
      calculations, on-line merchant account establishment, and a
      fully-integrated payment gateway. In addition, Verio's leading Web-hosting
      and domain name registration services are integrated to provide businesses
      with true one-stop shopping for all the components of an electronic
      commerce-enabled Web site. Once on-line, VerioStore customers' merchandise
      will be featured on the Stuff.com shopping portal operated by iMall, where
      potential customers can find and purchase their products. We also recently
      entered into an agreement with CyberSource(R), a leading supplier of
      electronic commerce transaction services, to offer international
      electronic commerce solutions capable of processing and settling on-line
      transactions in 29 different currencies. This allows our customers who are
      merchants to present products on their Web sites in multiple currencies,
      allowing shoppers who visit the site to buy products in a familiar
      currency. These merchants can then avoid having to process complicated
      currency conversions themselves. Under this agreement, Verio will resell
      CyberSource's services through our distribution channels, including our
      network of more than 4,000 resellers worldwide. We expect to continue to
      invest in creating a greater suite of electronic commerce packages as this
      market develops.
 
     - Web Site Design: Web site design is the development of the Web site
       content that will be displayed on the Web site when it is being viewed on
       the Internet. We rely principally on our resellers to create the Web
       sites for our customers. In addition to relying on the Web design
       services of our resellers, we offer Web design services to a select set
       of our customers. This may entail development of a basic Web page through
       to the development of a sophisticated electronic commerce Web site.
 
     We believe that more advanced Web-site based application products will
continue to expand as businesses require more sophisticated on-line commerce
capabilities. We are continually seeking to acquire technology from third
parties to incorporate with our existing solutions to provide more and more
functionality to our commerce product offerings, as well as exploring additional
Web-based services through internal development. In particular, our efforts are
focused on:
 
     - expanded Web-site based electronic commerce capabilities;
 
     - Web-based faxing and electronic mail;
 
     - aggregation of various messaging formats into a single point of contact;
 
     - "virtual offices" -- which is the creation of Web-based work groups
       through the use of common data, applications or other links;
 
     - audio and video appliances;
                                       59
<PAGE>   60
 
     - automated Web site development tools and templates;
 
     - basic automated marketing tools; and
 
     - multiple presence Web site hosting across multiple national and
       international data centers.
 
     We continue to assess potential opportunities to extend new offerings as
they become available, and to evaluate our ability to implement these solutions
in a cost-effective way while maintaining quality of service for our customers.
 
MARKETING
 
     Verio's marketing organization focuses on stimulating demand for Verio's
services and extending Verio's brands, and is responsible for advertising,
marketing communications and public relations. We have consolidated the
operations and marketing efforts of our acquired operations under the Verio
brand name, although in certain instances, where an acquired operation has
established particularly strong brand identity, such as Hiway and its
RapidSite(TM) product offering, we may continue to market particular products
and services under that name. Recently, we have focused significant efforts in
marketing campaigns and brand recognition. We rely on a combination of
traditional media and on-line advertising. We focus our traditional media
efforts on advertisements in major business and technical publications,
television commercials, radio spots and direct mail. We have undertaken national
public relations efforts to raise the awareness and visibility of Verio through
a national print, radio and television advertising campaign. We also have
commenced a joint marketing effort with NorthPoint Communications to market
digital subscriber line services in 21 cities nationwide. Our on-line marketing
program consists of general rotation and keyword-specific Web banner
advertisements. We became one of the world's largest Internet domain name
registrars and Web hosting companies by pioneering domain name registration
services and establishing preferential Web-based marketing relationships with
leading Internet media, search engine and portal companies such as America
Online, Netscape, Yahoo, Excite, Infoseek, and others. Other marketing vehicles
include collateral materials, trade shows, direct response programs and
management of our Web site. Public relations focuses on cultivating industry
analyst and media relationships with the goal of securing broad media coverage
and public recognition of the Verio brand name.
 
     On March 4, 1999, we entered into a strategic agreement with America
Online, under which, for a three year period, Verio has acquired exclusive
rights to market its Web hosting and business-focused electronic commerce
services on America Online's four key on-line media properties in the US:
America Online, CompuServe, AOL.COM and America Online's Digital City. The
agreement also includes the transition of nearly 7,000 AOL PrimeHost and
CompuServe BusinessWeb customers to Verio for continued Web hosting service.
America Online will receive guaranteed payments totaling a minimum of $42.5
million from us, and will also participate in future revenue sharing. Verio will
receive significant on-line advertising and promotion of a co-branded Verio and
America Online Web site that will offer a broad range of Verio Web hosting
products and electronic commerce solutions.
 
SALES AND DISTRIBUTION
 
     Verio utilizes multiple distribution channels in order to extend its reach
and leverage the service capabilities and brand names of its channel partners.
Verio uses a combination of direct sales, on-line marketing, telemarketing,
value-added resellers and private label resellers.
 
     Direct Sales. We have a direct sales force of more than 200 professionals.
These local sales representatives have a strong Internet technical background,
understand the local telco tariffs and the needs of their local business
community, and are familiar with local companies to assist in implementing
tailored solutions. Since these representatives are locally-based, they are able
to meet face-to-face to discuss a particular customer's Internet needs and
technical requirements and develop tailored solutions. We have developed
programs at the national level to attract and train high quality, motivated
sales representatives that have the necessary technical skills, experience and
knowledge. These programs include technical sales training, consultative selling
techniques, sales compensation plan development, and sales representative
recruiting
 
                                       60
<PAGE>   61
 
profile identification. Through the effective use of these initiatives, we plan
to continue to expand our direct sales force. At the local level, direct
marketing techniques are being used to target customers 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. We work with key vendors to assist in these direct
marketing efforts. We co-market with these vendors through direct mail programs,
joint seminar development and joint trade show involvement. Through the TABNet
acquisition, we acquired a centralized outbound and inbound telemarketing sales
capability targeted at offering Web hosting services.
 
     On-line Sales. We have an extensive on-line marketing program, consisting
of general rotation and keyword-specific Web banner advertisements, which
stimulate interest in and leads for our products and services. Much of this
on-line activity directs prospects to our on-line Web sites from which prospects
may make a product selection and order a product on-line. We are able to
generate a substantial amount of sales of our Web hosting products through this
selling technique as a result of the high degree of automation built into our
Web site provisioning process. Through our recently announced strategic
agreement with America Online, we expect to substantially expand Verio's
national brand name recognition through this major new on-line marketing
relationship.
 
     Resellers and Indirect Sales. We believe that indirect sales channels
contribute significantly to our growth, and have developed three primary
reseller partner programs that provide us with a formal indirect distribution
strategy. Through these programs, we have a worldwide indirect distribution
channel with over 4,000 resellers in the U.S. and over 170 other countries.
These programs include our:
 
     - Authorized Solutions Partner Program: This program offers our reseller
       the ability to share in the ongoing revenue stream of customers they
       bring to Verio. Authorized Solutions Partners include computer resellers,
       value-added resellers, systems integrators and other organizations
       focused on providing information technology hardware, software, and
       services to the business community. They typically have an established
       relationship with the prospective customer base, and a sales force
       capable of selling Internet services as part of the partner's suite of
       services.
 
     - Referral Partner Program: These partners include organizations such as
       Web designers, advertising agencies, and telco resellers. We target
       organizations that are less capable of, or interested in, selling
       Internet services, or where Internet services fall outside their core
       business interests.
 
     - Private Label Partner Program: This is a wholesale program which allows
       qualifying organizations to resell our services under their own brand.
 
     The benefits that we derive from these programs including greater market
reach without fixed overhead costs, and the ability to use partners to assist in
the delivery of complete solutions to meet customer needs. In addition to local
partnerships, we are working with several national companies to expand our
indirect sales capability. We also intend to pursue additional private label
original equipment manufacturer-like relationships with major telecommunications
carriers, similar to our current arrangement with NTT America. NTT America
recently has launched its branded Arcstar Internet service in the U.S., and is
reselling the full range of Verio services under this brand. We also are party
to this type of agreement with a number of the regional bell operating companies
and a large European telecommunications company.

TECHNOLOGY AND NETWORK OPERATIONS
 
     Overview. Verio owns and operates a national network, providing high
capacity Internet data transmission, highly reliable data transmission path
connecting Verio's customers to the Internet. Verio believes this network is
adequate for the provision of current and future planned access and services
needs. Verio's national network interconnects more than 29 national nodes and
over 200 local point of presence facilities across the United States. By
aggregating the capacity of data transmission over the Internet and capacity
requirements of our acquired operations onto one national network, we continue
to increase our operational control and efficiency, reduce costs, and provide
redundancy and higher quality service. In this way, we are able to address some
of the most significant challenges that an Internet service provider 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 regional, national and international Internet service
providers, sophisticated network management tools and engineering support
services. The reliability of the national network is the result of many factors,
including redundant routers and other critical hardware, carrier class
facilities at point of presence locations such as back-up power, fire
suppression and climate control, and redundant telecommunications lines. With
our substantial national capacity, network support capabilities, and peering
relationships, Verio has achieved "tier one" status as one of the largest
national, full service Internet network providers.
 
     National Network. As of March 31, 1999, the national network carried
traffic for 39 of the acquired Internet service providers. The remaining
providers' 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.
 
     Following is a diagram of Verio's national network as of March 31, 1999:
                                    [US MAP]
 
                                       62
<PAGE>   63
 
     Currently, the national network architecture includes a presence at
selected national exchange points and redundant network nodes to link our
regional networks to the national network. As of March 31, 1999, our network
included connectivity at:
 
     - the major public national exchange points -- MAE West, MAE East and the
       NY NAP;
 
     - the Palo Alto Internet Exchange (PAIX);
 
     - NASA Ames; and
 
     - other regional connecting points, including Seattle, Washington;
       Portland, Oregon; Los Angeles, Irvine, Sacramento and San Diego,
       California; Denver, Colorado; Orem, Utah; New Orleans, Louisiana; Dallas
       and Houston, Texas; St. Louis and Kansas City, Missouri; Chicago,
       Illinois; Ann Arbor, Michigan; Atlanta, Georgia; Tampa, Florida;
       Harrisburg, Philadelphia and Pittsburgh, Pennsylvania; Baltimore,
       Maryland; Rochester and New York City, New York; and Boston,
       Massachusetts.
 
     Each of these locations uses leading router technology. The equipment is
located in facilities leased from a variety of telco providers, including MCI
WorldCom, Sprint and others. These access points are linked, using a nationwide,
high-speed asynchronous transfer mode and clear line network infrastructure
ranging in capacity from DS-3 to OC-12. This network capacity is leased
primarily from Qwest and a variety of other national telecommunications
providers, including Sprint and MCI WorldCom. This combination of clear channel
circuits, asynchronous transfer mode and router architecture makes the network
reliable by diversifying the path of Internet traffic and maintaining redundant
paths. Our regional networks either co-locate at these access nodes or lease
connectivity from a local service provider such as a regional bell operating
company or other local exchange carrier to connect to our equipment.
 
     We are continuing to add national access nodes to serve additional parts of
the Midwest, Southern California, the Southeast and the Northeast, all of which
we currently plan to put on-line during 1999. Multiple national access nodes
facilitate connection of our regional operations to our national network. We
continue to add additional private peering points and access nodes as we acquire
more Internet service providers and expand operations, and to further increase
network capacity as the need for additional Internet data transmission capacity
arises.
 
     The national network is planned to allow for rapid expansion of Internet
data transmission capacity through scalable design supported by multiple local
access and interexchange carriers to provide the required Internet data
transmission capacity. We have begun the migration of selected links from
asynchronous transfer mode to clear line, over 10,000 miles of which has been
leased from Qwest. We have implemented nationwide OC-3 capacity and, on some
routes, OC-12 links to handle our projected traffic requirements.
 
     In March 1998, we entered into a 15-year capacity and services agreement
with Qwest Communications Corporation, which we amended in December 1998. Under
this agreement, we will have access to long haul capacity and ancillary services
on Qwest's nationwide MacroCapacity(SM) Fiber Network. Initially, the agreement
required that over the first seven years we must purchase, and Qwest must
provide, not less than $100.0 million of capacity and services, at agreed upon
prices. Under the amendment, we agreed to increase that commitment by an
additional $60 million and to extend the term of our minimum commitment from 7
to 10 years. With this extended contract and higher volume of service
commitment, we received improved pricing for our capacity purchases. This
contract provides us with the flexibility to deploy circuits from DS-3, at 45
megabits per second, to multiple OC-48, at 2.4 gigabits per second, as our
customer needs expand. We have the right to order capacity and services in
excess of the minimum commitment at any time during the 15-year term. We also
currently are a party to a number of other long haul capacity agreements with
additional telco providers. These agreements are for various terms and at varied
pricing. We anticipate that we will satisfy a substantial portion of our
capacity and ancillary services needs under the Qwest agreement, because we
believe that the pricing levels that we are entitled to under the amended
agreement will significantly reduce the per unit costs that we otherwise would
pay under our other existing long haul capacity agreements.
 
                                       63
<PAGE>   64
 
     We believe that the currently installed Cisco and Juniper Networks routers
will be sufficient to support our traffic routing needs up to and including OC-3
and OC-12 speeds. We are investigating and testing various options to support
higher than OC-12 speeds and Internet data transmission capacity requirements.
Our options include switching, higher capacity and faster routers, or hybrid
routing and switching solutions.
 
     Peering Relationships. Peering is the Internet practice under which
Internet service providers exchange each other's traffic without the payment of
settlement charges. The basis on which the large national providers 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 providers has driven industry peering practice. Recently, companies
that have previously offered peering have cut back or eliminated peering
relationships and are establishing new, more restrictive criteria for peering.
We believe that substantial traffic volume and national scale will continue to
be the focal criteria necessary to establish and maintain peering relationships.
Global network capabilities also may become a requirement. 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.
 
     Verio has established public or private peering relationships with all of
the major national Internet service providers, as well as with many smaller
domestic and international networks, and continues to evaluate additional
private peering proposals. By implementing our own national network and
establishing peering relationships with other national Internet service
providers, we believe we can lower the cost of our Internet transit and increase
the performance and reliability of our network operations. With over 100 peering
partners, including all of the largest Internet service providers, Verio's
network is considered a "tier one" national network. 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 Internet data transmission traffic at a higher capacity and in a
more efficient manner rather than to risk congestion and equipment failure at
public exchange points. We currently anticipate that, as our traffic grows, more
peering relationships can be obtained. However, no assurance can be given that
peering relationships will continue to be made available to us. Even if these
relationships are not maintained or established, we believe that it will be more
economical for Verio to maintain an exchange point transit agreement than to pay
other national providers for transit. See "Risk Factors -- We depend upon our
network infrastructure" and "-- Our costs will increase if we fail to maintain
our peering relationships."
 
     Web Hosting Operations. Through the iServer, TABNet and Hiway acquisitions,
we have developed high-performance, reliable, secure and scalable Web hosting
solutions, which we believe provide us with a significant competitive advantage.
These solutions consist of multiple proprietary Web hosting platforms that
incorporate automated functionality and a highly reliable network infrastructure
that includes multiple data centers monitored by our network operations center
seven days a week, twenty-four hours per day. Our strategy in developing our Web
hosting solutions focuses on utilizing proprietary technological innovations
that we integrate with third-party software and hardware to configure integrated
solutions.
 
     Web Hosting Platform. We have established multiple proprietary Web hosting
platforms through our acquisitions. As a result we can efficiently host up to
two thousand Web sites on a single server. Although industry-standard Web
servers can enable Web hosting, we believe that efficiently managing large
numbers of Web sites and users on a single shared server is technically
difficult and requires significant technological innovations. Accordingly, we
have focused our technology development efforts on creating various proprietary
operating system level tools to facilitate a high-density customer to server
ratio. We also have customized or developed Web server applications designed to
improve performance in a shared server environment and resource monitoring tools
designed to report and address scarcity of shared central processing units and
memory resources. Our solution can easily allow server groups to be added
seamlessly and to be monitored centrally wherever they are located. To address
the diverse requirements of our customers, we offer Web hosting services on a
range of operating systems and computing platforms.
 
                                       64
<PAGE>   65
 
     We also have developed proprietary software that allows us to provide our
services on an efficient and cost-effective basis by automating the following
back-end functions:
 
        (1) order-taking and processing;
 
        (2) customer billing via credit cards, check, bank transfer and accounts
            receivable;
 
        (3) account provisioning and activation;
 
        (4) server management and monitoring;
 
        (5) coordination of the electronic mail subsystem to integrate
            electronic mail forwarding, multiple electronic mail accounts on a
            single Web site and autoresponders;
 
        (6) inherent distributor-dealer-customer hierarchy of all data; and
 
        (7) support for third-party feature "plug-ins."
 
     In addition, we provide a front-end interface that allows a customer to set
up accounts, change account parameters, check Web site statistics quickly and
easily and verify billing information. "TQ software" was engineered to maximize
automation to achieve high levels of scalability, and the modular design allows
additional server groups to be supported easily. Language and branding
independence enables international value-added resellers and original equipment
manufacturers to localize for foreign languages and customize the interface
quickly and with minimal effort.
 
     Data Centers. We currently have data centers located in Orem, Utah; San
Francisco and Mountain View, California; Seattle, Washington; Dallas, Texas;
Boca Raton, Florida and Washington, D.C. An upgraded data center in the San
Francisco Bay Area is planned for 1999, and additional east coast data centers
as well as expansions of certain of our existing data centers also are being
planned. Primarily all of Verio's data centers include environmental controls,
back-up generators, Cisco routers and switches, and continuous monitoring
capabilities to ensure high-quality service with minimal interruptions.
 
     National Network Management. We consider world-class network management an
essential capability for network monitoring and expansion, maintaining high
customer satisfaction and improving network quality. We have established a
network operations center to allow continuous monitoring of the network 24 hours
per day, 7 days per week. Our network operations center also provides a single
point of contact for real-time network status information and customer technical
problem resolution. The network operations center is designed to provide
real-time alarming, event correlation, traffic management and forecasting, and
distributed notification of the network events and network status. We use many
leading edge systems to provide the network operations center capabilities. As
of March 31, 1999, we monitored the national network and the local networks of
approximately 27 of the Internet service providers we had acquired as of such
time.
 
     Engineering Support Services. We have negotiated national level telco
contracts with local exchange carriers, such as MCI WorldCom, providing
favorable terms for local transport. We plan to expand national purchasing and
leasing benefits as well as technical planning and support to improve the
performance, reliability and economics of our regional networks. National level
purchasing benefits include both cost and vendor performance issues as well
providing spare equipment and additional technical support from suppliers.
National level distribution agreements have been negotiated with a number of
additional national-scope suppliers. Specialized facility lease agreements have
also been established with companies such as Qwest, Sprint, MCI WorldCom and
Digital Equipment Corporation. We are pursuing additional vendor and telco
relationships in an effort to reduce the cost of equipment and improve network
quality.
 
     Technical Planning and Support. Our engineering team provides engineering
support for routing configurations, telco management and pricing, development of
our regional and national networks and purchasing and contract negotiation. The
engineering team also works to standardize certain network elements nationally,
improve performance and reduce network costs. Support includes Internet protocol
addressing support, training and technology. This effort of sharing ideas across
our operations is intended to enhance the engineering talent available locally
and to share best practices nationally.
 
                                       65

NATIONAL SUPPORT SERVICES
 
     In addition to our 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 Verio's services. These support services include
24x7 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 Verio 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. Our customer care combines the responsiveness
and on-site capabilities of our local operations with the scale economies of a
national customer support center. Our network operations center in Dallas,
Texas, enables us to provide responsiveness twenty-four hours per day, seven
days a week while maintaining the ability to provide on-site installation
assistance, hands-on troubleshooting and access to local experts who understand
the customer's business. As of March 31, 1999, we were providing customer care
services to 34 of the providers we had acquired and will offer services to all
of our regional operations as the national customer support center continues to
expand throughout 1999. The support center team is using a leading customer
support trouble ticketing and workflow management system offered by Vantive
Corporation. The system enables us to track, route, and report on customer
issues. It provides significant benefit in ensuring quality and timely care to
customers. Based on information received through the trouble ticketing system,
as well as through the centralized billing and collections system, we are able
to monitor network reliability and outage experiences. To date, this information
reflects that the outages experienced by our customers, for the most part, are
minor and attributable to ordinary course of business service interruptions,
telecommunication network capacity demands, and the customer's hardware and
software functionality issues. In certain instances, our customers experienced
downtime and outages in the course of our conversion of systems and processes
associated with our integration and consolidation efforts. While historically
Verio has not, as a general matter, provided service warranties or offered a
standard service credit policy, in the future we may as and to the extent that
it becomes a necessary or desirable commercial practice. To date, Verio has
provided credits resulting from network outages and system failures in certain
circumstances, but the amount of these credits has not been material. Certain of
the entities that we have acquired have offered and implemented various service
credit policies, some of which remain in effect with respect to customers of
those acquired entities. Again, however, credits required as a result of those
policies to date have not been material. We will continue to monitor network
outage experiences, and expect to record appropriate reserves if the level of
outage credits becomes material.
 
     Financial Information Management. We are in the process of converting all
of our acquired Internet service provider operations to the PeopleSoft(TM)
financial reporting system and the ADP payroll/human resources system, in order
to provide a central, standardized accounting system. As of March 31, 1999, 44
of our acquired operations were using the financial reporting system and 45 were
using the payroll/human resources system. These systems enable us 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 our initiative to implement
continuous improvement methodology and to create a learning organization.
 
     Billing and Collections. We have 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. As of March 31, 1999, this system served 37 of our acquired Internet
service operations. We are aggressively rolling out this billing platform to all
of our regional operations to centralize our billing operations.
 
NTT STRATEGIC RELATIONSHIP
 
     On April 7, 1998, Verio entered into agreements establishing a strategic
relationship with Nippon Telegraph and Telephone Corporation. Under these
agreements, upon the consummation of our initial public
 
                                       66
<PAGE>   67
 
offering, Nippon Telegraph and Telephone Corporation acquired 4,493,877 shares
of our common stock for approximately $100.0 million in aggregate consideration
and is entitled to designate one member to serve on Verio's board of directors.
See "Certain Related Party Transactions -- Other Transactions."
 
     In addition, Verio and Nippon Telegraph and Telephone Corporation's U.S.
affiliate, NTT America, Inc., entered into a three-year outside service provider
agreement, which took effect upon the completion of Nippon Telegraph and
Telephone Corporation's investment. Pursuant to this agreement, Verio was
designated as the preferred provider of Internet access and related services to
customers of NTT America on a reseller basis. Verio and Nippon Telegraph and
Telephone Corporation also will connect their backbones and establish a peering
and transit relationship. During the term of this agreement, NTT America will
pay Verio for the services provided by Verio at predetermined rates reflective
of the strategic relationship between the parties, under which Nippon Telegraph
and Telephone Corporation is entitled to "most favored customer" status and
pricing concessions. NTT America and Verio subsequently executed a further
agreement setting forth the details for implementation of the specific technical
and administrative aspects arising under the outside service provider agreement.
NTT America has now launched its branded Arcstar Internet service in the U.S.,
and will resell the full range of Verio services under this brand. Verio will
also provide NTT America with full back-office and engineering support.
 
SUBSIDIARY OWNERSHIP STRUCTURE
 
     While Verio now typically seeks to acquire 100% of new Internet service
providers' operations, Verio's early acquisition strategy was to acquire less
than 100% of its Internet service providers. In each of these cases, it obtained
the right to buyout the remaining equity in the future. As part of its
integration strategy, Verio has effected the buyouts of all but one of the
U.S.-based companies in which it did not initially acquire 100% ownership. With
the completion of these buyouts, Verio then undertook its efforts to consolidate
the management of the acquired operations in order to minimize administrative
costs.
 
     Verio currently holds a 6.7% fully diluted equity interest in VIA Internet,
Inc., which was formed in 1997 to pursue a strategy similar to that of Verio's
outside of the U.S. and Canada. See "Certain Related Party Transactions -- Other
Transactions." Verio has no contractual right to acquire the remaining equity of
VIANet, and has no present plan to integrate the operations of VIANet with those
of its own. Hiway owned minority and majority interests in certain entities that
provide Web hosting and other enhanced Internet services in various foreign
countries. Upon the completion of the Hiway acquisition, Verio acquired the
majority and minority equity positions held by Hiway at that time. Verio has
completed the acquisition of the remaining equity in one of these entities,
WWW-Service Online-Dienstleistungen AG. We may seek to acquire the remaining
equity of the other partially owned international entities in the future.
However, we also may decide to leave some equity in our international
subsidiaries in the hands of local owners in order to retain their continued
services and expertise in managing these distant operations.
 
COMPETITION
 
     The market for Internet access and related services is extremely
competitive. Verio 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:
 
     - national, regional and local Internet service providers;
 
     - global, national, and regional long distance and local exchange
       telecommunications companies;
 
     - cable television companies;
 
     - direct broadcast satellite and wireless communications providers;
 
     - on-line service providers; and
 
     - Web hosting providers, and providers of other enhanced value Internet
       services.
 
                                       67
<PAGE>   68
 
     Verio believes that the following are the primary competitive factors in
this market:
 
     - Maintaining a secure and reliable national network with sufficient
       capacity, quality of service and scalability to support continued growth.
 
     - Maintaining a knowledgeable and effective sales force and implementing
       broad and effective distribution channels.
 
     - Providing knowledgeable and capable technical support personnel, and
       prompt and efficient customer care services.
 
     - Maintaining Internet system engineering and other technical expertise.
 
     - Offering competitive prices.
 
     - Making timely introductions of new products and services.
 
     - Having sufficient financial resources.
 
     - Having a recognized and trusted brand name.
 
     Many of our competitors have significantly greater market presence, brand
recognition, and financial, technical, network capacity and personnel resources
than we do. All of the major long distance companies, also known as
interexchange carriers, offer Internet access services and compete with us. The
recent sweeping reforms in the federal regulation of the telecommunications
industry have created greater opportunities for local exchange carriers,
including the regional bell operating companies, to enter the Internet access
market. In order to address the Internet access requirements of the current
business customers of long distance and local carriers, there is a move toward
integrating horizontally through acquisitions of, joint ventures with, and the
wholesale purchase of Internet access from, Internet service providers by these
telecommunications companies. In addition, many of the major cable companies and
other alternative service providers -- such as those companies utilizing
wireless terrestrial and satellite-based service technologies -- have announced
their plans to offer Internet access and related services. Accordingly, we
expect that we will experience increased competition from traditional and
emerging telecommunications providers. Many of these companies, in addition to
their substantially greater network coverage, market presence, and financial,
technical and personnel resources, also have large existing commercial customer
bases. Furthermore, they may have the ability to bundle Internet access with
basic local and long distance telecommunications services. This bundling of
services may have an adverse effect on our ability to compete effectively with
them and may result in pricing pressure on us that would adversely affect our
business, financial condition and results of operations.
 
     The recent deployment and further planned deployment of broadband services
or high capacity data transmission capabilities by cable and telephone companies
through new technologies such as cable modems and various digital subscriber
lines technologies also creates further competitive pressure in Verio's
business. While these providers initially targeted the residential consumer,
more recently a number of digital subscriber lines providers also have announced
their intent to offer digital subscriber lines services to our target business
market. This may significantly affect the pricing of our Internet access service
offerings. Similar to the co-marketing arrangement which we entered into with
NorthPoint Communications in early 1999, a number of digital subscriber lines
providers have launched their services in conjunction with Internet service
providers, allowing those providers to offer Internet access over digital
subscriber lines circuits. These digital subscriber lines circuits, which
provide higher speed and lower latency Internet connections than a standard
dial-up phone connection, compete with our dedicated connectivity offerings.

operational functions are also located in various regional operation offices,
where Verio typically is party to lease agreements for administrative office
space sufficient for locally based personnel, as well as smaller site leases to
house network equipment. Hiway's principal executive offices and data center was
located in Boca Raton, Florida. The lease, which covers rentable area of
approximately 78,971 square feet, commenced on February 1, 1998 and is for a
term of seven years, expiring on January 31, 2005. Verio currently uses this
space to house locally-based personnel and as a data center. Hiway also entered
into a seven year lease for approximately 15,850 square feet of office space in
Mountain View, California. This lease commenced on June 1, 1995 and expires on
May 31, 2002. Verio currently uses this space for a data center and to house
locally-based personnel.
 
EMPLOYEES
 
     As of March 31, 1999, Verio employed approximately 1,390 people, including
full-time and part-time employees at our corporate headquarters in Colorado, our
network operations and customer support center in Texas and at our distributed
operational offices across the country and around the world. We consider our
employee relations to be good. None of our employees are covered by a collective
bargaining agreement.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
     The following discussion relates to Verio's exposure to market risk related
to changes in interest rates, and foreign currency exchange rates. This
discussion contains forward-looking statements that are subject to risks and
uncertainties. Actual results may differ materially due to a number of factors
including those set forth under the captions "We have substantial debt which may
impact our future operations and affect our ability to meet our debt
obligations" and "We may need to raise additional capital in order to remain
competitive" in the section titled "Risk Factors."
 
INTEREST RATE RISK
 
     Verio has limited exposure to financial market risks, including changes in
interest rates. At March 31, 1999, Verio had short-term investments of
approximately $354.0 million. These short-term investments consist of highly
liquid investments in debt obligations of highly rated entities with maturities
of between one and 360 days. These investments are subject to interest rate risk
and will fall in value if market interest rates increase. Verio expects to hold
these investments until maturity, and therefore expects to realize the full
value of these investments, even though changes in interest rates may affect
their value prior to maturity. If interest rates decline over time, this will
result in a reduction of our interest as our cash is reinvested at lower rates.
 
     Verio has debt that is substantial in relation to its stockholders' equity
and cash flow. At March 31, 1999, Verio had long term liabilities in the
aggregate amount of $690.3 million, representing 75% of total capitalization. A
change of interest rates would not affect our obligations under these
agreements. Increases in interest rates could, however, increase the interest
expense associated with future borrowings and borrowings under our bank credit
facility.
 
FOREIGN CURRENCY RATE RISK
 
     Verio does not currently have any significant foreign currency exposure.
However, a portion of its revenue, comprising less than 10%, is generated from
sources outside the United States. These payment obligations are generally
denominated in local currencies, and any currency devaluation would affect the
amount of revenues that Verio would receive from its international operations.
As these operations only represent a small portion of Verio's revenue, we do not
have any significant overall currency exposure at March 31, 1999. Verio does not
hedge against foreign currency rate changes.
 
     On January 1, 1999, 11 of 15 member countries of the European Union
established fixed conversion rates between their existing sovereign currencies
and the euro, and adopted the euro as their common legal currency. Verio has not
commenced any assessment of the effects of the euro conversion, and we are
unsure of the potential impact of the euro conversion on our international
operations. Based on the size of our international investments, these
fluctuations are not expected to have a material impact.

DIRECTORS COMPENSATION
 
     Each non-employee director receives an annual retainer fee of $5,000 and a
fee of $1,000 for each meeting of the board attended in person or $500 for each
meeting attended by telephone. The fee for board committee meetings is $500 per
meeting. A director may elect to receive these payments in the form of common
stock. On May 11, 1998 -- the effective date of the registration statement filed
with the Securities and Exchange Commission in connection with our initial
public offering -- each non-employee director was automatically granted an
option to acquire 30,000 shares of our common stock at an exercise price per
share equal to the price per share in the initial public offering of our common
stock less underwriting discounts and commissions. Such options vest and become
exercisable in three equal installments on each yearly anniversary of the grant
date. Non-employee directors elected or appointed to the board following the
initial public offering are granted automatically at the time of election or
appointment an option to acquire 30,000 shares of common stock with the same
terms and conditions at an exercise price equal to the then fair market value of
the common stock. After the initial three-year vesting period for such options,
non-employee directors receive automatic annual grants of options to acquire an
additional 3,000 shares of common stock at an exercise price equal to the fair
market value of the common stock at the date of grant. Such options vest and
become exercisable on the first anniversary of the grant date. In April 1998,
the Company adopted the 1998 Non-Employee Director Stock Incentive Plan -- which
we refer to in this prospectus as the Director Option Plan -- under which
options may be granted and shares of common stock may be issued to non-employee
directors in accordance with these compensation arrangements.
 
     On May 11, 1998, each of Messrs. Halstedt, Allen, Myhren, Salem and Still
were granted options to purchase up to 30,000 shares of common stock, at an
exercise price of $21.50 per share under the Director Option Plan. On September
11, 1998, Mr. Ito was granted options to purchase up to 30,000 shares of common
stock, at an exercise price of $20.50 per share under the Director Option Plan.
Each of Messrs. Myhren, Salem, Still and Ito have assigned their respective
options to Myhren Media, Inc., Providence Equity Partners Inc., Norwest Equity
Partners V, L.P. and NTT Rocky, Inc., respectively. By contract with Centennial
Holdings, Inc., Mr. Halstedt is required to transfer any economic benefit
deriving from such options to Centennial Holdings, Inc.

STOCK OPTIONS GRANTED IN 1998
 
     The following table contains information concerning the grant of stock
options by Verio under Verio's stock option plans to the Named Executive
Officers in 1998.
 
     Prior to the completion of Verio's initial public offering, 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 at
that time. Subsequent to Verio's initial public offering, all options were
granted at an exercise price equal to the market price of the common stock on
the last trading day before the date of grant.
 
                                       77
<PAGE>   78
 
     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 Securities and Exchange Commission and do not represent
Verio'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 our common stock and overall stock market conditions.
There can be no assurance that the amounts reflected in this table will be
achieved.

FISCAL YEAR-END OPTION VALUES
 
     The following table sets forth certain information with respect to the
Named Executive Officers regarding the stock options exercised during 1998. It
shows the aggregate number of unexercised options to purchase common stock
granted in all years and held by the Named Executive Officers as of December 31,
1998, and the value of unexercised in-the-money options, that is, options that
had a positive spread between the exercise price and the fair market value of
the common stock, as of December 31, 1998. The value of unexercised options at
year-end is based on the December 31, 1998 closing price of $22.375 per share of
our common stock as reported on the Nasdaq National Market.

EMPLOYMENT AGREEMENTS
 
     As a general matter, Verio does not enter into employment agreements, and
has not entered into employment agreements with any of its officers. Rather, the
employment relationship with each officer is "at will." However, in connection
with the initial employment of each officer, Verio and the officer executed an
offer letter, in which the general compensation and benefits provided to the
officer are outlined, including base salary, targeted annual bonus, option
grants, employee benefits and severance. The compensation levels established in
such offer letters are subject to change from time to time, at the discretion of
the Compensation Committee. In connection with Mr. Hribar's initial employment,
Verio agreed to guarantee a
 
                                       78
<PAGE>   79
 
minimum net equity value attributable to the options granted to Mr. Hribar on
the commencement of his employment and that vest and become exercisable at the
one-year anniversary of his initial employment, a total of 62,500 underlying
shares. The minimum net equity value fixed in Mr. Hribar's offer letter is $1
million. So long as he remains employed on that one-year anniversary date, if
the net equity value of those options on that date is less than $1 million, he
may elect to exercise this equity protection right for a period of 30 days
thereafter.
 
COMPENSATION PROTECTION AGREEMENTS
 
     Verio has entered into compensation protection agreements with each of the
Named Executive Officers and certain additional officers of Verio. Each of the
compensation protection agreements contains substantially similar terms. The
compensation protection agreements are for a term of three years, subject to
automatic yearly extensions. In no event will the compensation protection
agreements terminate within 12 months of a change in control of Verio. "Change
in control" includes the following:
 
        (a) An acquisition, other than directly from Verio, of any voting
     securities of Verio by any person immediately after which such person has
     beneficial ownership (as defined in the Exchange Act) of 40% or more of the
     combined voting power of Verio'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 the date the compensation protection
     agreements were approved by the board, are members of the board, cease for
     any reason to constitute at least a majority of the board (subject to
     certain provisos);
 
        (c) Approval by stockholders of Verio of a merger, consolidation or
     reorganization involving Verio, unless such merger, consolidation or
     reorganization satisfies certain specified conditions;
 
        (d) Any other merger, consolidation or reorganization 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 following a change in control, each
protected officer will receive the following compensation and benefits:
 
        (1) If a protected officer's employment with Verio is terminated within
     12 months following a change in control by Verio for cause or by reason of
     the protected officer's disability (as defined in the compensation
     protection agreements), death or retirement, or by the protected officer
     other than for good reason (as defined in the compensation protection
     agreements), then Verio must pay to the protected officer the accrued
     compensation due through the date of termination. Accrued compensation
     includes base salary, reimbursement for reasonable and necessary expenses
     incurred by the protected officer on behalf of Verio during the period
     ending on the termination date, and vacation pay.
 
        (2) If a protected officer's employment is terminated within 12 months
     of a change in control for any other reason than specified above, the
     protected officer will receive:
 
           (A) his or her accrued compensation;
 
           (B) a bonus amount equal to the product of a fraction, the numerator
        of which is the number of days in Verio'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
 
                                       79
<PAGE>   80
 
        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;
 
           (C) an amount equal to two times the sum of the protected officer's
        annual base salary in effect immediately prior to the change in control,
        plus the bonus amount in (B). However, the amount paid to Mr. Jaschke
        will be three times that sum;
 
           (D) until the third anniversary of the termination date, the same
        rights with respect to benefits provided by Verio, as were provided to
        the protected officer as of the effective date of the compensation
        protection agreement, 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
        Verio's stock option and other stock incentive plans or arrangement.
 
     The compensation protection agreements further provide that the protected
officers are not 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 Verio's employee benefit plans and
other applicable programs, policies and practices then in effect. The
compensation protection agreements contain a "gross-up" provision pursuant to
which any severance payment, which would be subject to certain excise taxes
occurring as a result of a change in control, would include an additional
gross-up payment resulting in the protected officer retaining an additional
amount equal to these excise taxes.
 
STOCK OPTION AND INCENTIVE PLANS
 
  1996 Stock Option Plan
 
     Verio's 1996 stock incentive plan was adopted and approved by the board in
May 1996 and by Verio's stockholders in June 1996. In February 1998, the 1996
plan was amended to reserve a total of 2,205,300 shares of common stock for
issuance under this plan. At March 31, 1999, options to purchase 317,045 shares
of common stock granted under the 1996 plan had been exercised, options to
purchase 1,509,688 shares of common stock were outstanding and no additional
options to purchase shares of common stock remained available for grant. Of the
317,045 shares issued upon exercise of options, a total of 48,250 were issued
upon exercise prior to their respective exercise vesting dates, as permitted by
the terms of the 1996 plan. As a result, these shares are subject to repurchase
by Verio at their respective exercise prices, until the date on which they would
have become exercisable. The outstanding options were exercisable at a weighted
average exercise price of $6.06 per share. Outstanding options to purchase an
aggregate of 861,197 shares were held by employees who are not officers or
directors of Verio.
 
     All options granted under the 1996 plan that expire after the date of the
1996 plan amendment without having been exercised increase the number of options
available for grant under the 1998 Stock Incentive Plan and are no longer
available for grant under the 1996 plan. The 1996 plan will terminate in 2006,
unless sooner terminated by the board.
 
     The board has delegated administration of the 1996 plan to its compensation
committee. The compensation committee is made up of two or more non-employee
directors within the meaning under Rule 16b-3 of the Exchange Act. Awards under
the 1996 plan may consist of stock options that qualify under Section 422 of the
Internal Revenue Code of 1986, as amended, commonly referred to as incentive
stock options, or stock options that do not qualify under that provision,
commonly referred to as non-qualified stock options.
 
     The compensation committee may grant incentive stock options to employees
and officers of Verio or any of our affiliates, and non-qualified stock options
to employees, officers, directors or consultants of Verio or any
 
                                       80
<PAGE>   81
 
of our affiliates. The compensation committee may set the terms of such grants,
subject to the restrictions in the 1996 plan. Incentive stock option grants are
subject to the following limitations:
 
     - the term of any incentive stock option may not be longer than ten years;
 
     - the term of any incentive stock option granted to an individual
       possessing more than 10% of the combined voting power of Verio or an
       affiliate may not be longer than five years;
 
     - 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;
 
     - the exercise price of incentive stock options may not be less than the
       fair market value of the underlying shares on the grant date; and
 
     - the exercise price of any incentive stock option granted to an individual
       possessing more than 10% of the combined voting power of Verio or an
       affiliate may not be less than 110% of the fair market value of the
       underlying shares on the grant date.
 
     The exercise price for non-qualified stock options may not be less than 85%
of the fair market value of the underlying shares on the grant date. As of March
31, 1999, no such below-market grant has been made.
 
     During an optionee's lifetime, only an optionee can exercise an incentive
stock option or non-qualified stock option. He or she cannot transfer such
options other than by will or the laws of descent and distribution. In addition,
with respect to a non-qualified stock option, an optionee may not transfer such
options other than 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 status as an employee, director or consultant of Verio terminates
for any reason other than termination because of death or disability may
exercise, in the three-month period following the termination, or such longer or
shorter period specified in the option, that portion of the options that is
exercisable at the time of the termination unless such options terminate or
expire sooner by their terms. In the event the optionee becomes disabled, the
options vested as of the date of disability may be exercised prior to the
earlier of their expiration date or 12 months from the date of the optionee's
disability, or as specified in the option. In the event the optionee dies, the
options vested as of the date of death may be exercised prior to the earlier of
such option's specified expiration date or 18 months from the date of the
optionee's death, or as specified in the option.
 
     The 1996 plan provides that if any of the following events occurs, (1) any
surviving corporation shall assume any outstanding options, (2) the options will
continue to be effective, or (3) the options will expire if they are not
exercised prior to such event:
 
     - a dissolution or liquidation of Verio;
 
     - a merger or consolidation in which Verio is not the surviving
       corporation;
 
     - a reverse merger in which Verio is the surviving corporation but the
       shares of Verio's outstanding common stock immediately prior to the
       merger are converted into other property, whether in the form of
       securities, cash or otherwise; or
 
     - any other capital reorganization in which our stockholders receive less
       than 50% of the outstanding voting shares of the surviving corporation.
 
  1997 California Stock Option Plan
 
     Verio's 1997 stock incentive plan was adopted by the board in February
1997, and approved by Verio's stockholders in April 1997. In February 1998, the
1997 plan was amended, with the approval of the board and our stockholders, to
reserve a total of 795,400 shares of common stock for issuance under this plan.
At March 31, 1999, options to purchase 26,109 shares of common stock had been
exercised under the 1997 plan, options to purchase 408,673 shares of common
stock were outstanding and there were no options available for grant as the
remaining options were transferred to the 1998 Stock Incentive Plan. The
outstanding options were exercisable at a weighted average exercise price of
$13.47 per share. Outstanding options to purchase an
 
                                       81
<PAGE>   82
 
aggregate of 381,523 shares were held by employees who are not officers or
directors of Verio, and the remaining outstanding options to purchase 70,000
shares are held by Mr. Johnson's estate.
 
     All options granted under the 1997 plan that expire after the date of the
1997 plan amendment without having been exercised increase the number of options
available for grant under Verio's 1998 Stock Incentive Plan and are no longer
available for grant under the 1997 plan.
 
     The 1997 plan may be administered by the board or the compensation
committee. The 1997 plan provides for the granting to employees of Verio and our
subsidiaries or parent corporations of incentive stock options, and for the
granting to our employees and independent contractors of non-qualified stock
options. The 1997 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 payment upon exercise. An
optionee cannot transfer his or her options 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
plan must be at least equal to the fair market value, as determined by the
board, of the common stock on the grant date. The exercise price of all
non-qualified stock options granted under the 1997 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 our
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 plan may
not exceed ten years. The payment 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 applicable option agreement.
 
     The 1997 plan provides that if we merge with or into another corporation or
consolidate, sell substantially all of our assets or like transaction involving
Verio in which the stockholders before the transaction do not retain a majority
interest in Verio occurs, 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 plan, the options not otherwise
exercisable will terminate immediately before the completion of the transaction.
 
     The 1997 plan will terminate automatically in 2007 unless it is terminated
sooner. The board has the authority to amend, suspend or terminate the 1997
plan, subject to stockholder approval of certain amendments. However, no action
may be taken which will affect any share of common stock previously issued and
sold or any option previously granted under the 1997 plan without the optionee's
consent.
 
  1998 Stock Incentive Plan
 
     Verio's 1998 stock incentive plan, which was adopted by the board in
February 1998, was amended and restated as of March 19, 1998. Under this plan we
reserved 6,199,300 shares of common stock for issuance under the 1998 incentive
plan, which is increased by:
 
     - any shares of common stock available for future awards under the 1997
       plan as of our initial public offering; and
 
     - any shares of common stock represented by awards under the 1996 plan and
       the 1997 plan, that are forfeited, expired or cancelled following our
       initial public offering.
 
     Since our initial public offering, all further option grants, including
Hiway's options assumed by Verio in the Hiway acquisition, are made solely under
the 1998 incentive plan.
 
     At March 31, 1999, options to purchase 310,592 shares of common stock had
been exercised under the 1998 incentive plan, options to purchase 5,515,371
shares of common stock were outstanding, and 650,745 options remained available
for grant. The outstanding options were exercisable at a weighted average
 
                                       82
<PAGE>   83
 
exercise price of $21.63 per share. Outstanding options to purchase an aggregate
of 3,846,188 shares were held by employees who are not officers or directors of
Verio.
 
     The purpose of the 1998 incentive plan is to attract and retain the best
available personnel, to provide additional incentive to employees, directors and
consultants of Verio and our related entities and to promote the success of our
business. The 1998 incentive plan provides for the granting to employees of
incentive stock options, and the granting to employees, directors and
consultants of Verio and our related entities of nonstatutory stock options,
stock appreciation rights, dividend equivalent rights, restricted stock,
performance units, performance shares, and other equity-based rights.
 
     With respect to 1998 plan awards granted to directors or officers, the 1998
incentive plan is administered by the board or a committee designated by the
board made up of two or more non-employee directors so that such awards would be
exempt from Section 16(b) of the Exchange Act. With respect to 1998 plan awards
granted to other participants, the 1998 incentive plan is administered by the
board or a committee designated by the board. In each case, the respective plan
administrator shall determine the provisions, terms and conditions of each
award.
 
     An optionee cannot transfer an incentive stock option other than by will or
the laws of descent or distribution. Each incentive stock option is exercisable
during the lifetime of the optionee only by such optionee. Other 1998 plan
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 1998 plan awards will be
determined by the respective plan administrator. With respect to an employee who
owns stock possessing more than 10% of the voting power of all classes of our
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 1998 plan awards will be such price as
determined by the respective plan administrator, but not less than 85% of the
fair market value of the stock. The form of payment for the shares of common
stock upon exercise or purchase of a 1998 plan award will be determined by the
respective 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 an award for
a certain period of time following the recipient's termination of service with
Verio, disability or death, such 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 such award, whichever occurs first.
 
     Unless terminated sooner, the 1998 incentive plan will terminate
automatically in 2008. The board has the authority to amend, suspend or
terminate the 1998 incentive plan, subject to stockholder approval of certain
amendments. However, no action may be taken which will affect awards previously
granted under the 1998 incentive plan unless agreed to by the affected grantees.
 
  1998 Employee Stock Purchase Plan
 
     Verio's 1998 stock purchase plan was approved by the board in February 1998
and has been approved by the stockholders. The stock purchase plan was amended
and restated as of April 13, 1998. The stock purchase plan is intended to
provide employees with an opportunity to purchase common stock through payroll
deductions under Section 423 of the Internal Revenue Code. An aggregate of
3,000,000 shares of common stock has been reserved for issuance under the stock
purchase plan subject to adjustment in the event of a change in the common stock
or capital structure of Verio. All employees of Verio, its subsidiaries and
parent corporations (as defined in the plan) designated by the administrator of
the stock purchase plan, whose customary employment is for more than five months
in any calendar year and more than 20 hours per week are eligible to
participate. Employees of Verio are eligible to participate after they have been
employed with us for six months. 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.
 
     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 began on the effective date of the stock purchase
plan, which was the effective date of Verio's registration statement relating to
our initial public offering, and ends on May 14, 1999. Additional purchase
periods will commence each May 15 and November 15. Accrual periods are generally
six month periods commencing each May 15 and November 15. The initial accrual
period commenced on the effective date of the stock purchase plan and ended on
November 14, 1998. Exercise dates are the last day of each accrual period. The
administrator of the stock purchase plan may elect to shorten the purchase
period then in progress in the event:
 
        (1) we merge with or into another corporation;
 
        (2) sell all or substantially all of our assets; or
 
        (3) or enter into other transactions in which our stockholders before
     the transaction own less than 50% of the total combined voting power of
     Verio's outstanding securities following the transaction.
 
     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. When the purchase right is
exercised, an authorized deduction from the participant's salary is used to
purchase shares of common stock. The price per share at which shares of common
stock are to be purchased during any accrual period is the lesser of (1) 85% of
the fair market value of the common stock on the date of the grant of the
option, or (2) 85% of the fair market value of the common stock on the exercise
date. 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 Internal
Revenue Code.
 
     The stock purchase plan will be administered by the board 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.
 
  1998 Non-Employee Director Stock Incentive Plan
 
     In April 1998, the board adopted the 1998 non-employee director plan which
was subsequently approved by our stockholders. The total number of shares
available for grant is 550,000 shares of common stock. This is available for
option grants and stock issuances to members of the board who are not employees
of Verio. At March 31, 1999, options to purchase 210,000 shares of common stock
are outstanding under the non-employee director plan. Options to purchase an
additional 340,000 shares of common stock are available for grant.
 
     The purposes of the 1998 non-employee director plan are to attract and
retain the best available non-employee directors, to provide them additional
incentives, and to promote the success of our business. The 1998 non-employee
director plan establishes two programs for the grant of awards to non-employee
directors: the automatic option grant program and the stock fee program.
 
                                       84
<PAGE>   85
 
     Under the automatic option grant program, each of the six non-employee
directors serving on the board at the time of our initial public offering were
automatically granted an option to acquire 30,000 shares of common stock at an
exercise price per share equal to the fair market value at the date of grant.
These options will vest and become exercisable in three equal installments on
each yearly anniversary of the grant date. Each non-employee director appointed
to the board also will be granted automatically, at the time of election or
appointment, an option to acquire 30,000 shares of common stock with the same
terms and conditions at an exercise price equal to the then fair market value of
the common stock. After the initial three year vesting period for such options,
each non-employee director will receive automatic annual grants of options to
acquire an additional 3,000 shares of common stock at an exercise price equal to
the fair market value at the date of grant. Such options will vest and become
fully exercisable on the first anniversary of the grant date.
 
     Each automatic option grant has a term of eight years and is transferable
to the extent provided in the option agreement. The payment for exercising an
option may consist of cash, check, shares of common stock, the assignment of
part of the proceeds from the sale of shares acquired upon exercise of the
option or any combination of these. In the event we merge with or into another
corporation, sell substantially all of our assets, a person becoming more than a
50% owner of Verio or a like transaction involving Verio in which our
stockholders before the transaction do not retain a majority interest in Verio,
immediately prior to the transaction, one-third of the shares subject to the
options to purchase 30,000 shares of common stock will vest and become
exercisable and all of the shares subject to the options to purchase 3,000
shares of common stock will vest and become exercisable. Upon consummation of
such transaction all such options will terminate, unless they are assumed by the
successor company. In the event of a hostile takeover of Verio or change in the
majority of the board through contested elections, the vesting of all such
options will likewise accelerate as described above, but the options will remain
exercisable according to their terms.
 
     Under the stock fee program, each non-employee director will be eligible to
apply all or any portion of the annual retainer and meeting fees otherwise
payable in cash to the non-employee director to the acquisition of shares of
common stock. The non-employee director must make the stock purchase election
prior to the start of the calendar year for which the election is to be in
effect. The first year for which such elections may be made is 1999. On the
first trading day following the due date for payment of a portion of the annual
retainer fee or the date of any meeting in a calendar year for which the
election is effective, the portion of the annual retainer or meeting fee subject
to such election automatically will be applied to the acquisition of shares of
common stock by dividing the selected dollar amount by the then fair market
value per share of the common stock. The number of shares will be rounded down
to the next whole share.
 
     The 1998 non-employee director plan is administered by the board or a
committee designated by the board made up of two or more non-employee directors
so that such awards would be exempt from Section 16(b) of the Exchange Act. The
1998 plan administrator shall approve forms of the non-employee director award
agreement for use under the plan, determine the terms and conditions of
non-employee director awards, and construe and interpret the terms of the 1998
non-employee director plan and non-employee director awards granted pursuant
thereto.
 
     The 1998 non-employee director plan will terminate automatically in 2008
unless it is terminated sooner. The board has the authority to amend, suspend or
terminate the 1998 non-employee director plan, subject to stockholder approval
of certain amendments. However, no action may be taken which will affect awards
previously granted under the plan unless agreed to by the affected non-employee
directors.
 
401(K) PLAN
 
     In January 1997, we implemented an employee savings and retirement plan
(the "401(k) Plan") covering certain of our employees who have at least one
month of service 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. We may make contributions to the 401(k) Plan on behalf of eligible
employees. Employees become 20% vested in these Verio contributions after one
year of service, and increase their vested percentages by an additional 20% for
each year of service thereafter. The
 
                                       85
<PAGE>   86
 
401(k) Plan is intended to qualify under Section 401 of the Internal Revenue
Code so that contributions by employees or by Verio 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 Verio, if
any, will be deductible by Verio 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. Verio made no contributions to the
401(k) Plan in 1996 or in 1997. Verio does not presently expect to make any
contributions to the 401(k) Plan during fiscal 1998.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     During 1998, the Compensation Committee consisted of Messrs. Allen, Myhren
and Schovee. Mr. Schovee served as its Chairman. No member of the Compensation
Committee was at any time during the fiscal year ended December 31, 1998, or at
any other time, an officer or employee of Verio or any of our subsidiaries. No
member of the Compensation Committee 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 board or the Compensation Committee.
 
LIMITATION ON LIABILITY AND INDEMNIFICATION MATTERS
 
     The Certificate of Incorporation and Bylaws of Verio provide that we will
indemnify to the fullest extent permitted by Section 145 of the General
Corporation Law of the State of Delaware, as it now exists or as amended, all
directors and officers. The Certificate of Incorporation and Bylaws also
authorize us to indemnify our employees and other agents, at our option, to the
fullest extent permitted by Section 145, as it now exists or as amended. We
entered into agreements to indemnify our directors and officers, in addition to
indemnification provided for in our charter documents. These agreements, among
other things, provide for the indemnification of our 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 Verio, arising out of such person's services as a
director or officer of Verio, any subsidiary of Verio or any other company or
enterprise to which such person provides services at the request of Verio to the
fullest extent permitted by applicable law. We believe that these provisions and
agreements will assist us in attracting and retaining qualified persons to serve
as directors and officers.
 
     Section 102(b)(7) of the General Corporation Law of the State of Delaware
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 (1) for any breach of the director's duty of
loyalty to the corporation or its stockholders, (2) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (3) under Section 174 of the General Corporation Law of the State of
Delaware or (4) for any transaction from which the director derived an improper
personal benefit. Our Certificate of Incorporation provides for the elimination
of personal liability of a director for breach of fiduciary duty, as permitted
by Section 102(b)(7) of the General Corporation Law of the State of Delaware.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of Verio
pursuant to the provisions contained in our charter documents, the General
Corporation Law of the State of Delaware or otherwise, we have 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 Verio of expenses incurred or paid by a
director, officer or controlling person of Verio in the successful defense of
any action, suit, or proceeding) is asserted by such director, officer or
controlling person, we will, unless in the opinion of our counsel the matter has
been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by us is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
     We have purchased 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.

                       CERTAIN RELATED PARTY TRANSACTIONS
 
TRANSACTIONS WITH DIRECTORS AND EXECUTIVE OFFICERS
 
     In connection with Mr. Hribar's employment, Verio agreed to guarantee a
minimum net equity value attributable to the options granted to Mr. Hribar on
the commencement of his employment and that vest and become exercisable at the
one-year anniversary of his initial employment, a total of 62,500 underlying
shares. The minimum net equity value fixed in Mr. Hribar's offer letter is $1
million. So long as he remains employed on that one-year anniversary date, if
the net equity value of those options on that date is less than $1 million, he
may elect to exercise this equity protection right for a period of 30 days
thereafter.
 
     As a condition to the closing of the acquisition of Hiway, all related
party indebtedness was to be repaid to Hiway on or prior to closing. However,
Verio agreed to waive the condition that Arthur L. Cahoon repay his indebtedness
to Hiway in the principal amount of $280,409 with interest at the then prime
rate.
 
OTHER TRANSACTIONS
 
     Brooks Fiber Properties, Inc. On March 18, 1998, in response to an offer by
Brooks, we entered into an agreement with Brooks pursuant to which we agreed to
repurchase the $50.0 million principal amount of the 1997 Notes held by Brooks
for an aggregate net purchase price of approximately $54.5 million, plus accrued
interest. A portion of the proceeds from the sale of the March 1998 Notes was
used to effect the repurchase described above.
 
     Nippon Telegraph and Telephone Corporation. On May 15, 1998, the settlement
date in connection with our initial public offering, pursuant to a Stock
Purchase and Master Strategic Relationship Agreement, dated as of April 7, 1998,
between Verio and Nippon Telegraph and Telephone Corporation, Nippon Telegraph
and Telephone Corporation purchased 4,493,877 shares of our common stock for
approximately $100.0 million. We granted Nippon Telegraph and Telephone
Corporation certain registration rights with respect to the common stock it had
acquired.
 
     We also entered into an investment agreement with Nippon Telegraph and
Telephone Corporation on April 7, 1998, providing for certain arrangements
effective from and after the completion of its investment in Verio, some or all
of which could have the effect of delaying, deferring or preventing a change of
control of Verio. In particular, so long as Nippon Telegraph and Telephone
Corporation continues to hold at least 50% of the aggregate number of shares of
common stock acquired by it, we have agreed to appoint an individual designated
by Nippon Telegraph and Telephone Corporation to our board of directors. The
initial designee, Yukimasa Ito, will serve for an initial term ending as of the
third annual stockholder meeting following the closing of our initial public
offering. Thereafter, for so long as Nippon Telegraph and Telephone Corporation
continues to meet the share ownership requirement, we have agreed, subject to
certain exceptions, to nominate as a member of the board at each subsequent
election of the applicable class of directors a person designated by Nippon
Telegraph and Telephone Corporation who will be subject to election by our
stockholders.
 
     In addition, Nippon Telegraph and Telephone Corporation has agreed on
behalf of itself and its affiliates to certain "standstill" restrictions
pursuant to which it and its affiliates may only make open market or privately
negotiated purchases of additional voting securities, including our common
stock, so long as its total holdings, including those of its affiliates, do not
exceed 17.5% of our fully diluted common stock after taking into account such
acquisition. The "standstill" obligations terminate five years after the
completion of its investment. Nippon Telegraph and Telephone Corporation also
has agreed, among other things, that it will not (1) solicit proxies or
participate in a proxy solicitation or otherwise seek to influence voting with
respect to Verio, (2) call a stockholders meeting, or (3) make any announcement
or proposal for a tender offer that would result in it owning more than 17.5% of
our common stock on a fully diluted basis. In addition, Nippon Telegraph and
Telephone Corporation has agreed that in connection with any offer or agreement
by a third party to acquire over 30% of the voting power of Verio or over 50% of
the assets or earning power of Verio, it will not transfer any securities of
Verio in connection with an acquisition proposal, unless such acquisition
proposal has been recommended by our board or our board has not publicly
recommended against such
 
                                       87
<PAGE>   88
 
acquisition proposal within three months of the public announcement or
presentation to it of such acquisition proposal.
 
     The investment agreement also imposes certain limitations on Nippon
Telegraph and Telephone Corporation's ability to dispose of the shares of common
stock that it has acquired. We have been granted rights of first offer and
rights of first refusal in the event that Nippon Telegraph and Telephone
Corporation proposes to sell some or all of the shares that it has acquired. The
specific terms of these rights vary depending upon the quantity of shares
proposed to be sold and other terms of the proposed sale. The investment
agreement also precludes Nippon Telegraph and Telephone Corporation from
transferring common stock to certain parties specified by Verio (which list may
include no more than 15 specified parties at any one time) that are or are
likely to become our competitors or, subject to certain conditions, to any
person that as a result of such transfer would beneficially own more than 10% of
our common stock.
 
     In connection with the investment agreement, Verio and Nippon Telegraph and
Telephone Corporation also entered into an outside service provider agreement,
under which we were designated as the preferred provider of Internet access and
related services to customers of NTT America on a reseller basis. In addition
Verio and Nippon Telegraph and Telephone Corporation agreed to connect their
backbones and establish a peering and transit relationship, and that we would
provide NTT America with full back-office and engineering support. NTT America
has agreed to pay us for our services at predetermined rates reflective of the
strategic relationship between the parties, under which Nippon Telegraph and
Telephone Corporation is entitled to "most favored customer" status and pricing
concessions. Under the outside service provider agreement, we agreed to continue
to negotiate the specific terms of these arrangements with it. See
"Business -- NTT Strategic Relationship." Recently, we executed a further
strategic partner services agreement with NTT America describing the details for
implementing the specific technical and administrative aspects arising under the
outside service provider agreement. NTT America recently has launched its
branded Arcstar Internet service in the U.S., and will resell the full range of
Verio services under this brand. Under the investment agreement, Nippon
Telegraph and Telephone Corporation has designated three individuals to be
employed by Verio in corporate development, technical and marketing positions to
assist in implementing and carrying out its commercial relationship with Verio.
 
     VIANet. We have invested a total of approximately $8.25 million in
convertible preferred stock in VIA Internet, Inc. which represents 6.7% of the
fully diluted outstanding capital stock of VIANet. We have no right to acquire
the remaining equity of VIANet. Although, with the iServer, TABNet and Hiway
acquisitions, Verio gained a substantial international Web hosting presence, our
board of directors has determined that its investment in VIANet currently will
be the primary component of its international expansion strategy in the Internet
access market in the near term. However, we also may pursue direct investments
in certain international markets where appropriate opportunities exist. We
believe that our indirect strategy through VIANet currently is the most
effective means to leverage our resources in pursuing Internet access business
internationally.
 
     Mr. Hribar and Mr. Halstedt serve as members of VIANet's board of
directors.

                             PRINCIPAL STOCKHOLDERS
 
     The following table sets forth the beneficial ownership of Verio's common
stock, as of April 19, 1999, by:
 
        (1) each stockholder known by Verio to own beneficially more than five
     percent, in the aggregate, of Verio's common stock;
 
        (2) each director of Verio who owns shares of Verio's common stock;
 
        (3) the Named Executive Officers determined for the fiscal year ended
     December 31, 1998 who own shares of Verio's common stock;
 
        (4) all executive officers and directors of Verio as a group who own
     shares of Verio's common stock; and
 
        (5) the number of shares of Verio's common stock subject to options or
     warrants owned by any of the above-mentioned persons that are currently
     exercisable or exercisable within 60 days of April 19, 1999.
 
     The beneficial ownership is calculated based on 36,990,259 total shares of
common stock outstanding as of April 19, 1999. In presenting 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 owned by such
person that are currently exercisable or exercisable within 60 days of April 19,
1999 are deemed outstanding; provided, that such shares are not deemed
outstanding for the purpose of computing the percentage of ownership of any
other person. Except as indicated below 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 person's
name.
 
     The ownership percentage shown for Nippon Telegraph and Telephone
Corporation is higher than the maximum percentage of fully diluted shares that
it was permitted to purchase in its investment in Verio because the percentage
of beneficial ownership following our initial public offering reflected in this
table is based on outstanding and not fully diluted shares.

beneficially own the shares owned by Brooks as a result of the acquisition of
Brooks by WorldCom, which resulted in Brooks becoming a wholly owned subsidiary

these options. Mr. Salem disclaims beneficial ownership of these options.

                            DESCRIPTION OF THE NOTES
 
     The old notes were issued and the new notes will be issued under the
indenture between Verio and U.S. Bank Trust National Association, as trustee.
The indenture is subject to and governed by the Trust Indenture Act of 1939, as
amended. Except as otherwise indicated, the following summary applies to both
the old notes and the new notes. In this summary, the word "Verio" refers to
Verio and not to any of its subsidiaries, and the term "notes" means the old
notes and the new notes. A copy of the indenture is available upon request to
Verio, 8005 South Chester Street, Suite 200, Englewood, Colorado 80112;
attention: General Counsel; telephone: (303) 645-1900.
 
     The form and terms of the new notes will be identical in all material
respects to the form and terms of the old notes, except that the new notes will
be registered under the Securities Act. As a result, the new notes will not be
subject to some of the transfer restrictions and registration rights applicable
to the old notes. See "The Exchange Offer."
 
     The following is a summary of material provisions of the new notes. It does
not purport to be complete and is subject to, and is qualified in its entirety
by reference to, the Trust Indenture Act, and to all of the provisions of the
indenture, including the definitions of certain terms and those terms made a
part of the indenture by reference to the Trust Indenture Act, as in effect on
the date of the indenture. We urge you to read the indenture because it, and not
this summary, defines your rights as holders of the notes. For definitions of
certain capitalized terms used in the following summary, see "Certain
Definitions."
 
GENERAL
 
     The notes:
 
     - are general unsecured obligations of Verio;
 
     - rank equally with all Verio's unsecured unsubordinated indebtedness;
 
     - are senior to all Verio's unsecured subordinated indebtedness;
 
     - are subordinated to all Verio's secured indebtedness and indebtedness of
       Verio's subsidiaries;
 
     - have been issued only in fully registered form without coupons, in
       denominations of $1,000 principal amount and integral multiples of such
       amount; and
 
     - will not be subject to any service charge for any registration of
       transfer, exchange or redemption, except in certain circumstances, a tax
       or other governmental charge may be imposed.
 
     Principal of, premium, if any, and interest on the notes are payable, and
the notes are exchangeable and transferable, at the office or agency of Verio in
New York City maintained for such purposes, which initially will be the
corporate trust office of the trustee. See "-- Book-Entry; Delivery and Form."
 
MATURITY, INTEREST AND PRINCIPAL
 
     The notes are limited to $400,000,000 aggregate principal amount and will
mature on December 1, 2008. Verio will not be required to make any mandatory
sinking fund payments in respect of the notes. Interest on the notes will accrue
at a rate of 11 1/4% per annum and be payable in cash semi-annually in arrears
on June 1 and December 1, commencing June 1, 1999. Verio will make each interest
payment to the registered holders on the immediately preceding May 15 or
November 15, as the case may be. Interest on the notes will accrue from the most
recent interest payment date to which interest has been paid or duly provided
for or, if no interest has been paid or duly provided for, from the Issue Date.
Cash interest will be computed on the basis of a 360-day year of twelve 30-day
months. If Verio 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 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 notes.

REDEMPTION
 
     Optional Redemption. The notes are redeemable, at Verio's option, in whole
or in part, on or after December 1, 2003 upon not less than 30 nor more than 60
days' written notice. The notes may be redeemed at the following redemption
prices, expressed as a percentage of principal amount, plus accrued and unpaid
interest, if any, to the applicable redemption date, if redeemed during the
twelve-month period beginning on December 1 of the years indicated below:

</TABLE>
 
     In addition, prior to December 1, 2001, Verio may redeem, at its option, up
to a maximum of 35% of the initially outstanding aggregate principal amount of
notes from the net proceeds of an Equity Sale -- which is the issuance in one or
more transactions of Capital Stock, other than Disqualified Stock, of Verio to
one or more Strategic Equity Investors or in any Public Equity Offering for
aggregate gross cash proceeds of $50.0 million or more -- at a redemption price
equal to 111.250% of the principal amount of the notes, together with accrued
and unpaid interest to the date of redemption. However, at least $260.0 million
aggregate principal amount of notes must be 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. If less than all the notes are to
be redeemed, selection of the notes for redemption will be made pro rata, by lot
or such other method as the trustee in its sole discretion deems appropriate and
just. However, any redemption pursuant to the provisions relating to an Equity
Sale will be made on a pro rata basis or on as nearly a pro rata basis as
practicable, subject to the Depository Trust Company's procedures. No notes of a
principal amount of $1,000 or less may be redeemed in part. Notice of redemption
will be mailed by first-class mail at least 30 but not more than 60 days before
the redemption date to each holder of notes to be redeemed at its registered
address. If any note is to be redeemed in part only, the notice of redemption
that relates to such note must state the portion of the principal amount to be
redeemed. A new note in a principal amount equal to the unredeemed portion will
be issued in the name of the holder upon surrender for cancellation of the
original note. Upon giving of a redemption notice, interest on the notes called
for redemption will cease to accrue from and after the date fixed for redemption
and such notes will cease to be outstanding. Interest on the notes will continue
to accrue if Verio defaults in providing the funds for such redemption.
 
RANKING
 
     The indebtedness evidenced by the notes ranks:
 
     - senior in right of payment to all subordinated indebtedness of Verio;
 
     - equally in right of payment with all other existing and future
       unsubordinated indebtedness of Verio including the 1997 Notes and the
       March 1998 Notes; and
 
     - junior to all Verio's secured indebtedness and indebtedness of its
       subsidiaries.
 
     Verio has no existing unsecured and unsubordinated indebtedness or any
existing subordinated indebtedness. Accordingly, there is no existing debt that
is subordinated to the notes.
 
     Verio is a holding company with limited assets and no significant business
operations of its own. Verio operates its business through its subsidiaries. Any
right of Verio and its creditors, including holders of the notes, to participate
in the assets of any of Verio'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
 
                                       92
<PAGE>   93
 
March 31, 1999, there would have been approximately $21.0 million of secured
indebtedness outstanding to which holders of notes would have been effectively
subordinated in right of payment and approximately $14.7 million of subsidiary
indebtedness to which holders of notes would have been structurally
subordinated, all of which is included in the secured long-term figure above. In
addition, the $70.0 million revolving credit 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 notes are effectively subordinated to the credit
facility to the extent of the value of such assets. For a discussion of certain
adverse consequences of Verio being a holding company and of the terms of
potential future indebtedness of Verio and its subsidiaries, see "Risk
Factors -- We have substantial debt which may impact our future operations and
affect our ability to meet our debt obligations."
 
CERTAIN COVENANTS
 
     The indenture contains, among others, the following covenants:
 
     Limitation on Additional Indebtedness. Verio 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:
 
        (1) Verio will be permitted to incur Indebtedness (including Acquired
     Indebtedness); and
 
        (2) 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. Verio will not, and will not permit any
of the Restricted Subsidiaries to, make, directly or indirectly, any Restricted
Payment unless:
 
        (1) no Default shall have occurred and be continuing at the time of or
     upon giving effect to such Restricted Payment;
 
        (2) immediately after giving effect to such Restricted Payment, Verio
     would be able to incur $1.00 of Indebtedness under (x) the proviso of the
     covenant "Limitation on Additional Indebtedness" or (y) solely in the case
     of a Restricted Payment constituting an Investment of cash or Newly
     Acquired Assets, clause (g) of the definition of Permitted Indebtedness;
     and
 
        (3) immediately after giving effect to such Restricted Payment, the
     aggregate amount of all Restricted Payments declared or made on or after
     the Prior Issue Date (assuming that the indenture had been in effect as of
     the Prior Issue Date) and all Designation Amounts made on or after the
     Prior Issue Date (assuming that the indenture had been in effect as of the
     Prior Issue Date) does not exceed an amount equal to the sum of, without
     duplication:
 
           (a) 50% of the Consolidated Net Income of Verio accrued on a
        cumulative basis during the period beginning on January 1, 1998 and
        ending on the last day of the fiscal quarter of Verio immediately
        preceding the date of such proposed Restricted Payment (or, if such
        cumulative Consolidated Net Income of Verio for such period is a
        deficit, minus 100% of such deficit); plus
 
           (b) the aggregate net cash proceeds received by Verio either (x) as
        capital contributions to Verio after the Prior Issue Date or (y) from
        the issue and sale (other than to a Restricted Subsidiary of Verio) of
        its Capital Stock (other than Disqualified Stock) on or after the Prior
        Issue Date (including upon exercise of warrants, options or rights);
        plus
 
           (c) the aggregate net proceeds received by Verio from the issuance
        (other than to a Restricted Subsidiary of Verio) on or after the Prior
        Issue Date of its Capital Stock (other than Disqualified Stock) upon the
        conversion of, or in exchange for, Indebtedness of Verio; plus
 
                                       93
<PAGE>   94
 
           (d) in the case of the disposition or repayment (in whole or in part)
        of any Investment constituting a Restricted Payment made after the Prior
        Issue Date (assuming that the indenture had been in effect as of the
        Prior Issue Date) (except for Investments made (x) pursuant to clause
        (7) of the second following paragraph that are not subject to clause (e)
        or (f) of this paragraph below, and (y) pursuant to clauses (8) or (9)
        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
        Verio that was made subject to a Designation after the Prior Issue Date
        (assuming that the indenture had been in effect as of the Prior 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
        Verio 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 Prior Issue Date (assuming that the
        indenture had been in effect as of the Prior Issue Date) in an ISP which
        has been (or which is deemed to be because of the assumption set forth
        in the previous parenthetical clause) included as a Restricted Payment
        under this clause (3) pursuant to the last paragraph of this covenant to
        the extent such ISP thereafter (x) becomes or has become a Wholly Owned
        Restricted Subsidiary or is merged with Verio or (y) is a New ISP that
        becomes or has become a Restricted Subsidiary or is merged with Verio,
        less, in either such case, any amounts credited pursuant to the
        immediately preceding clause (d) in respect of any such Investment.
 
     For purposes of the preceding clauses (b)(y) and (c), as applicable, the
value of the aggregate net proceeds received by Verio 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 Verio 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):
 
        (1) the payment of any dividend or other distribution within 60 days
     after the date of declaration thereof if at such date of declaration such
     payment would be permitted by the provisions of the indenture;
 
        (2) the purchase, redemption, retirement or other acquisition of any
     shares of Capital Stock of Verio in exchange for, or out of the net cash
     proceeds of the substantially concurrent issue and sale (other than to a
     Restricted Subsidiary of Verio) of, shares of Capital Stock of Verio (other
     than Disqualified Stock); provided that any such net cash proceeds are
     excluded from clause (3)(b) of the second preceding paragraph;
 
        (3) 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 Verio) of (x) Capital Stock (other than
     Disqualified Stock) of Verio or (y) other Subordinated Indebtedness to the
     extent that its stated maturity for the payment of principal thereof is not
     prior to the 180th day after the final stated maturity of the notes;
     provided that any such net cash proceeds are excluded from clause (3)(b) of
     the second preceding paragraph;
 
        (4) (a) so long as no Default shall have occurred and be continuing,
     Investments constituting Restricted Payments by Verio or any Restricted
     Subsidiary in a New ISP or a person that becomes or since the Prior Issue
     Date has become a New ISP as a result of such Investment; and
 
                                       94
<PAGE>   95
 
           (b) so long as no Default shall have occurred and be continuing,
     Investments constituting Restricted Payments by Verio 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 Verio (provided that any such proceeds are excluded from clause
     (3)(b) of the second preceding paragraph) or (y) such that the aggregate
     amount of all Investments in Existing ISPs that are made after the Prior
     Issue Date pursuant to this subclause (b)(y) would not exceed $25.0 million
     in aggregate;
 
        (5) 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;"
 
        (6) 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 Verio 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
     notes;
 
        (7) 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 Verio or (2) issue or sale of Capital Stock (other than
     Disqualified Stock) of Verio (other than to a Restricted Subsidiary of
     Verio); provided that any such proceeds are excluded from clause (3)(b) of
     the second preceding paragraph;
 
        (8) loans or advances to employees of Verio or any Restricted Subsidiary
     made in the ordinary course of business, including to fund the purchase of
     Capital Stock of Verio (provided that any proceeds from such purchase are
     excluded from clause (3)(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;
 
        (9) 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 Verio
     and the ISPs or other persons engaged principally in an Internet Service
     Business in an aggregate amount not to exceed $50.0 million outstanding at
     any time; and
 
        (10) 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 (4)(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 Verio and such net cash proceeds
are excluded from clause (3)(b) of the first paragraph above, then the
application of such net cash proceeds as set forth in such clause (4)(b)(x)
shall be deemed "substantially concurrent" if they are subsequently released for
immediate application as contemplated by such clause (4)(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 clause
(3) of the first paragraph of this covenant, amounts expended since the Prior
Issue Date (assuming that the Indenture had been in effect on the Prior Issue
Date) pursuant to clauses (1), (4)(a), (4)(b)(y), (5), (6) and (9) (to the
extent remaining outstanding) of the second preceding paragraph above shall be
included, without duplication, as Restricted Payments.
 
     Limitation on Liens Securing Certain Indebtedness. Verio 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 Verio or
any Restricted Subsidiary, whether now owned or hereafter acquired, or any
proceeds therefrom, which secure either (x) Subordinated Indebtedness unless the
notes are secured by a Lien on such
 
                                       95
<PAGE>   96
 
property, assets or proceeds that is senior in priority to the Liens securing
such Subordinated Indebtedness or (y) Indebtedness of Verio that is not
Subordinated Indebtedness, unless the notes are equally and ratably secured with
the Liens securing such other Indebtedness, except, in the case of this clause
(y), Permitted Liens.
 
     Limitation on Business. Verio 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. Verio will not permit any Restricted Subsidiary, directly or
indirectly, to assume, guarantee or in any other manner become liable with
respect to:
 
        (1) any Subordinated Indebtedness; or
 
        (2) any Indebtedness of Verio that is not Subordinated Indebtedness
            (other than, in the case of this clause (2), 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
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 (2), 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 Verio or a Restricted
Subsidiary of Verio to any person that is not an Affiliate of Verio 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 Verio, 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. If a Change of Control occurs (the date being the
"Change of Control Date"), Verio shall make an offer to purchase (the "Change of
Control Offer"), on a business day (the "Change of Control Payment Date") not
later than 60 days following the Change of Control Date, all notes then
outstanding at a purchase price equal to 101% of the 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 notes, not less than 25 days nor more than 45 days before
the Change of Control Payment Date. The Change of Control Offer is required to
remain open for at least 20 business days and until the close of business on the
Change of Control Payment Date.
 
     Except as described above with respect to a Change of Control, the
indenture will not contain provisions that permit the holders of the notes to
require that Verio repurchase or redeem the notes in the event of a takeover,
recapitalization or similar transaction which may be highly leveraged.
 
     If a Change of Control Offer is made, there can be no assurance that Verio
will have available funds sufficient to pay for all of the notes that might be
delivered by holders of notes seeking to accept the Change of Control Offer.
Verio 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 Verio and purchases all notes validly tendered
and not withdrawn under such Change of Control Offer.

     If Verio is required to make a Change of Control Offer, Verio will comply
with all applicable tender offer laws and regulations, including, to the extent
applicable, Section 14(e) and Rule 14e-1 under the Exchange Act, and any other
applicable securities laws and regulations.
 
     Limitation on Dividends and Other Payment Restrictions Affecting Restricted
Subsidiaries. Verio 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 Verio or any Restricted Subsidiary;
 
        (b) pay any Indebtedness owed to Verio or any Restricted Subsidiary;
 
        (c) make any Investment in Verio or any Restricted Subsidiary; or
 
        (d) transfer any of its properties or assets to Verio or to any
     Restricted Subsidiary, except for (in each case except as otherwise noted
     in the following clause (2)):
 
           (1) any encumbrance or restriction in existence on the Issue Date;
 
           (2) 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;
 
           (3) customary non-assignment provisions;
 
           (4) any encumbrances or restrictions pertaining to an asset subject
        to a Lien to the extent set forth in the security documentation
        governing such Lien;
 
           (5) 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;
 
           (6) 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 notes than those under or pursuant to the agreement being
        replaced or the agreement evidencing the Indebtedness refinanced;
 
           (7) 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
 
           (8) 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 indenture and the notes and other Indebtedness that is
        solely an obligation of Verio, 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 Verio or any Restricted Subsidiary, customary restrictions on
        transactions with affiliates, and customary subordination provisions
        governing Indebtedness owed to Verio or any Restricted Subsidiary.

     Disposition of Proceeds of Asset Sales. Verio will not, and will not permit
any Restricted Subsidiary to, make any Asset Sale unless:
 
        (a) Verio 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, Cash
     Equivalents or Qualified Consideration, 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 Verio 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).
 
     Verio or the applicable Restricted Subsidiary, as the case may be, may:
 
        (1) 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 Verio 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;
 
        (2) 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
 
        (3) 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 Verio 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 (2) of the preceding sentence or invested in
Replacement Assets within the 365-day period as set forth in clause (3) shall
constitute "Excess Proceeds." Any Excess Proceeds not used as set forth in
clause (1) 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, Verio shall make an offer to purchase (an "Asset Sale Offer"), from all
holders of the notes, that aggregate principal amount of 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 notes tendered
pursuant to an Asset Sale Offer is less than the Offer Excess Proceeds, Verio or
any Restricted Subsidiary may use such deficiency for general corporate
purposes. If the principal amount of notes validly tendered and not withdrawn by
holders thereof exceeds the amount of notes which can be purchased with the
Offer Excess Proceeds, 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 Verio is required to make an Asset Sale Offer, Verio 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. Verio will not permit any Restricted Subsidiary to issue any
Preferred Stock (other than to Verio or a Restricted Subsidiary).
 
     Limitation on Transactions with Affiliates. Verio 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 Verio or any Wholly Owned Restricted Subsidiary) or any beneficial
holder of 10% or more of the Common Stock of Verio or any officer or director of
Verio (each, an "Affiliate Transaction"), unless the terms of the Affiliate
Transaction are set forth in writing, and are fair and reasonable to Verio 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, Verio may obtain a written opinion from an Independent Financial
Advisor stating that the terms of such Affiliate Transaction to Verio 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 Verio and the Restricted Subsidiaries, as the case may be, and,
therefore, shall be permitted under this covenant.
 
     However, the restrictions in this covenant shall not apply to:
 
        (1) transactions with or among, or solely for the benefit of, Verio
     and/or any of the Restricted Subsidiaries;
 
        (2) transactions pursuant to agreements and arrangements existing on the
     Issue Date;
 
        (3) 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 Verio
     or such Restricted Subsidiary, as the case may be, and (y) in the good
     faith judgment of Verio or the applicable Restricted Subsidiary, the Fair
     Market Value of the consideration received by Verio or such Restricted
     Subsidiary, as the case may be, reasonably approximates the Fair Market
     Value of the services provided;
 
        (4) dividends paid by Verio pursuant to and in compliance with the
     covenant "Limitation on Restricted Payments;"
 
        (5) customary directors' fees, indemnification and similar arrangements,
     consulting fees, employee salaries bonuses, employment agreements and
     arrangements, compensation or employee benefit arrangements or legal fees;
 
        (6) transactions contemplated by any of the Permitted Affiliate
     Agreements as in effect on the Issue Date; and
 
        (7) grants of customary registration rights with respect to securities
     of Verio.
 
     Verio is required to use, or to cause each Restricted Subsidiary to use,
its commercially reasonable best efforts to ensure that each person in which
Verio 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.
 
                                       99
<PAGE>   100
 
     Reports. Whether or not Verio has a class of securities registered under
the Exchange Act, Verio shall furnish without cost to each holder of notes and
file with the trustee and file with the Securities and Exchange Commission:
 
        (1) within the applicable time period required under the Exchange Act,
     after the end of each fiscal year of Verio, the information required by
     Form 10-K, or any successor form, under the Exchange Act with respect to
     such period;
 
        (2) 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 Verio, the information required by Form 10-Q, or any successor
     form, under the Exchange Act with respect to such period; and
 
        (3) any current reports on Form 8-K, or any successor forms, required to
     be filed under the Exchange Act.
 
     Limitation on Designations of Unrestricted Subsidiaries. Verio will not
designate any Subsidiary of Verio (other than a newly created Subsidiary in
which no Investment has previously been made) as an "Unrestricted Subsidiary"
under the indenture (a "Designation") unless:
 
        (a) no Default shall have occurred and be continuing at the time of or
     after giving effect to such Designation;
 
        (b) except in the case of a Permitted Investment or an Investment made
     pursuant to clause (7) or (9) of the third paragraph of the covenant
     "Limitation on Restricted Payments," immediately after giving effect to
     such Designation, Verio would be able to incur $1.00 of Indebtedness under
     (x) the proviso of the covenant "Limitation on Additional Indebtedness" or
     (y) solely in the case of a Designation with respect to a Subsidiary having
     assets which are substantially comprised of cash, or Newly Acquired Assets,
     clause (g) of the definition of Permitted Indebtedness; and
 
        (c) Verio would not be prohibited under the indenture (assuming that the
     indenture had been in effect on the Prior Issue Date) 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 Verio or any other Restricted
     Subsidiary in such Restricted Subsidiary on such date.
 
     In the event of any such Designation made on or after the Prior Issue Date,
Verio shall be deemed to have made an Investment constituting a Restricted
Payment pursuant to the covenant "Limitation on Restricted Payments" for all
purposes of the indenture in the Designation Amount. Neither Verio 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 Verio
     may pledge Capital Stock or Indebtedness of any Unrestricted Subsidiary on
     a nonrecourse basis such that the pledgee has no claim whatsoever against
     Verio 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."
 
                                       100
<PAGE>   101
 
     In addition, Verio will not revoke any Designation of a Subsidiary as an
Unrestricted Subsidiary (a "Revocation") unless:
 
        (a) no Default shall have occurred and be continuing at the time of and
     after giving effect to such Revocation; and
 
        (b) all Liens and Indebtedness of such Unrestricted Subsidiary
     outstanding immediately following such Revocation would, if incurred at
     such time, have been permitted to be incurred for all purposes of the
     indenture.
 
     All Designations and Revocations must be evidenced by Board Resolutions
delivered to the trustee certifying compliance with the foregoing provisions.
 
     Limitation on Status as Investment Company. Verio will not, and will not
permit any of its Subsidiaries or controlled Affiliates to, conduct its business
in a fashion that would cause Verio 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
Verio'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.
 
     Verio will not:
 
        (1) 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
 
        (2) 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 Verio and the
     Restricted Subsidiaries on a consolidated basis, unless, in the case of
     either (1) or (2):
 
           (a) Verio shall be the continuing person or, if Verio 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 Verio under the notes and the 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), Verio or
        the surviving entity (assuming such surviving entity's assumption of
        Verio's obligations under the notes and the 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
        Verio 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
 
                                       101
<PAGE>   102
 
           (e) Verio 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
        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 Verio in accordance with the foregoing in which Verio 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 Verio 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, Verio or
such Restricted Subsidiary, as the case may be, under the indenture with the
same effect as if such successor corporation had been named as Verio or such
Restricted Subsidiary therein; and thereafter, except in the case of (1) any
lease or (2) any sale, assignment, conveyance, transfer, lease or other
disposition to a Restricted Subsidiary of Verio, Verio shall be discharged from
all obligations and covenants under the indenture and the notes.
 
     For all purposes of the indenture and the 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
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 Verio 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.
 
EVENTS OF DEFAULT
 
     The following are "Events of Default" under the indenture:
 
        (1) default in the payment of interest on the notes when it becomes due
     and payable and continuance of such default for a period of 30 days or
     more; or
 
        (2) default in the payment of the principal of, or premium, if any, on
     the notes when due; or
 
        (3) default in the performance, or breach, of any covenant described
     under "-- Certain Covenants -- Change of Control," "-- Disposition of
     Proceeds of Asset Sales" or "-- Consolidation, Merger, Sale of Assets,
     Etc."; or
 
        (4) default in the performance, or breach, of any covenant in the
     indenture (other than defaults specified in clause (1), (2) or (3) above),
     and continuance of such default or breach for a period of 30 days or more
     after written notice to Verio by the trustee or to Verio and the trustee by
     the holders of at least 25% in aggregate principal amount of the
     outstanding notes (in each case, when such notice is deemed received in
     accordance with the indenture); or
 
        (5) 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 Verio 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
 
        (6) any holder of at least $7.5 million in aggregate principal amount of
     Indebtedness of Verio or any Material Restricted Subsidiary shall commence
     judicial proceedings or take any other action to foreclose upon, or dispose
     of assets of Verio 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, Verio or any Material
     Restricted Subsidiary shall not have
 
                                       102
<PAGE>   103
 
     obtained, prior to any such foreclosure or disposition of assets, a stay of
     all such actions that remains in effect; or
 
        (7) 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 Verio 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
 
        (8) certain events of bankruptcy, insolvency, reorganization,
     administration or similar proceedings with respect to Verio or any Material
     Restricted Subsidiary shall have occurred.
 
     If an Event of Default (other than an Event of Default specified in clause
(8) above with respect to Verio) occurs and is continuing, then the trustee or
the holders of at least 25% in principal amount of the outstanding notes may, by
written notice, and the trustee upon the request of the holders of not less than
25% in principal amount of the outstanding notes shall, declare the principal
amount of, premium (if any) on, and any accrued and unpaid interest on, all
outstanding 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 (8) above with respect to Verio occurs and is
continuing, then the principal amount of, premium (if any) on, and any accrued
and unpaid interest on, all outstanding notes shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of
the trustee or any holder.
 
     After a declaration of acceleration, the holders of a majority in aggregate
principal amount of outstanding notes may, by notice to the trustee, rescind
such declaration of acceleration if all existing Events of Default, other than
nonpayment of the principal of, premium (if any) on, and any accrued and unpaid
interest on, the notes that has become due solely as a result of such
acceleration, have been cured or waived and if the rescission of acceleration
would not conflict with any judgment or decree. The holders of a majority in
principal amount of the outstanding notes also have the right to waive past
defaults under the 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 notes.
 
     No holder of any of the notes has any right to institute any proceeding
with respect to the indenture or any remedy thereunder, unless the holders of at
least 25% in principal amount of the outstanding notes have made written
request, and offered reasonable security or indemnity, to the trustee to
institute such proceeding as trustee, the trustee has failed to institute such
proceeding within 60 days after receipt of such notice and the trustee has not
within such 60-day period received directions inconsistent with such written
request by holders of a majority in principal amount of the outstanding notes.
Such limitations do not apply, however, to a suit instituted by a holder of a
note for the enforcement of the payment of the principal of, premium (if any)
on, or any accrued and unpaid interest on, such note on or after the respective
due dates expressed in such note.
 
     During the existence of an Event of Default, the trustee is required to
exercise such rights and powers vested in it under the indenture and use the
same degree of care and skill in its exercise thereof as a prudent person would
exercise under the circumstances in the conduct of such person's own affairs.
Subject to the provisions of the indenture relating to the duties of the
trustee, if an Event of Default shall occur and be continuing, the trustee is
not under any obligation to exercise any of its rights or powers under the
indenture at the request or direction of any of the holders unless such holders
shall have offered to such trustee reasonable security or indemnity. Subject to
certain provisions concerning the rights of the trustee, the holders of a
majority in principal amount of the outstanding notes have the right to direct
the time, method and place of conducting any proceeding for any remedy available
to the trustee or exercising any trust or power conferred on the trustee.
 
     The trustee will, within 45 days after the occurrence of any Default, give
to the holders of the notes notice of such Default known to it, unless such
Default shall have been cured or waived; provided that the trustee
 
                                       103
<PAGE>   104
 
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.
 
     Verio is required to furnish to the trustee annually a statement as to its
compliance with all conditions and covenants under the indenture.
 
DEFEASANCE
 
     Verio may at any time terminate all of its obligations with respect to the
notes ("defeasance"), except for certain obligations, including those regarding
any trust established for a defeasance and obligations to register the transfer
or exchange of the notes, to replace mutilated, destroyed, lost or stolen notes
as required by the indenture and to maintain agencies in respect of notes. Verio
may at any time terminate its obligations under certain covenants set forth in
the indenture, some of which are described under "-- Certain Covenants" above,
and any omission to comply with such obligations shall not constitute a Default
with respect to the notes ("covenant defeasance"). To exercise either defeasance
or covenant defeasance, Verio must irrevocably deposit in trust, for the benefit
of the holders of the notes, with the trustee money (in United States dollars)
or U.S. government obligations (denominated in United States dollars), or a
combination thereof, in such amounts as will be sufficient to pay the principal
of, and premium, if any, and interest on the notes to redemption or maturity and
comply with certain other conditions, including the delivery of a legal opinion
as to certain tax matters.
 
SATISFACTION AND DISCHARGE
 
     The indenture will be discharged and will cease to be of further effect
(except as to surviving rights or registration of transfer or exchange of notes)
as to all outstanding notes when either:
 
        (a) all such notes theretofore authenticated and delivered (except lost,
     stolen or destroyed notes that have been replaced or paid and notes whose
     payment has been deposited in trust or segregated and held in trust by
     Verio and thereafter repaid to Verio or discharged from such trust) have
     been delivered to the trustee for cancellation; or
 
        (b) (1) all such notes not delivered to the trustee for cancellation
     have become due and payable and Verio has irrevocably deposited or caused
     to be deposited with the trustee as trust funds in trust for the purpose an
     amount of money sufficient to pay and discharge the entire indebtedness on
     the notes not delivered to the trustee for cancellation, for principal
     amount, premium, if any, and accrued interest to the date of such deposit;
 
           (2) Verio has paid all sums payable by it under the indenture; and
 
           (3) Verio has delivered irrevocable instructions to the trustee to
        apply the deposited money toward the payment of the notes at maturity or
        on the redemption date, as the case may be.
 
     In addition, Verio 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
 
     Verio may at any time, when authorized by resolutions of the Board, and the
trustee, without the consent of the holders of the notes, amend, waive or
supplement the indenture or the notes for certain specified purposes, including,
among other things, curing ambiguities, defects or inconsistencies, maintaining
the qualification of the indenture under the Trust Indenture Act or making any
change that does not adversely affect the rights of any holder. Other amendments
and modifications of the indenture and the notes may be made by Verio and the
trustee by supplemental indenture with the consent of the holders of not less
than a
 
                                       104

majority of the aggregate principal amount of the outstanding notes. However, no
modification or amendment may, without the consent of the holder of each
outstanding note affected thereby:
 
        (1) reduce the principal amount of, change the fixed maturity of, or
     alter the redemption provisions of, the notes;
 
        (2) change the currency in which any notes or amounts owing thereon is
     payable;
 
        (3) reduce the percentage of the aggregate principal amount outstanding
     of notes which must consent to an amendment, supplement or waiver or
     consent to take any action under the indenture or the notes;
 
        (4) impair the right to institute suit for the enforcement of any
     payment on or with respect to the notes;
 
        (5) waive a default in payment with respect to the notes;

     notes;
 
        (7) following the occurrence of a Change of Control or an Asset Sale,
     alter Verio's obligation to purchase the notes in accordance with the
     indenture or waive any default in the performance thereof;
 
        (8) affect the ranking of the notes in a manner adverse to the holder of
     the notes; or

                         BOOK-ENTRY; DELIVERY AND FORM
 
     Except as set forth under "-- Certificated Securities," the new notes will
be issued in the form of one global new note. Such global new note will be
deposited with, or on behalf of, the Depository Trust Company and registered in
the name of the Depository Trust Company or its nominee. Except as set forth
below, such global new note may be transferred, in whole and not in part, only
to the Depository Trust Company or another nominee of the Depository Trust
Company.
 
     Investors may hold their beneficial interests in such global new note
directly through the Depository Trust Company if they have an account with the
Depository Trust Company or indirectly through organizations which have accounts
with the Depository Trust Company.
 
     The Depository Trust Company has advised Verio as follows: The Depository
Trust Company 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 Trust Company was created to hold securities of institutions
that have accounts with the Depository Trust Company ("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 Trust Company'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 Trust Company'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 the global new note, the Depository Trust Company will
credit, on its book-entry registration and transfer system, the principal amount
of the new notes represented by such global new note to the accounts of
participants. Ownership of beneficial interests in such global new note will be
limited to participants or persons that may hold interests through participants.
Ownership of beneficial interests in 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 Trust Company, with respect to participants'
interest, and such participants, with respect to the owners of beneficial
interests in such 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 such global new note.
 
     So long as the Depository Trust Company, or its nominee, is the registered
holder and owner of a global new note, the Depository Trust Company 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 indenture.
Except as set forth below, owners of beneficial interests in the global new note
will not be entitled to have the new notes represented by the 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 global new note. Verio
understands that under existing industry practice, in the event an owner of a
beneficial interest in the global new note desires to take any action that the
Depository Trust Company, as the holder of the global new note is entitled to
take, the Depository Trust Company 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 Trust Company or
its nominee will be made to the Depository Trust Company or its nominee, as the
case may be, as the registered owner and holder of the global new note.
 
     Verio expects that the Depository Trust Company 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 global new note
as shown on
 
                                       120
<PAGE>   121
 
the records of the Depository Trust Company or its nominee. Verio 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.
Verio 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 Trust Company 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 note may not be transferred except as a
whole by the Depository Trust Company to a nominee of the Depository Trust
Company or by a nominee of the Depository Trust Company to the Depository Trust
Company or another nominee of the Depository Trust Company.
 
     Although the Depository Trust Company has agreed to the foregoing
procedures in order to facilitate transfers of interests in the global new note
among participants of the Depository Trust Company, 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, Verio nor the paying agent will
have any responsibility for the performance by the Depository Trust Company or
its participants or indirect participants of their respective obligations under
the rules and procedures governing their operations.
 
     Certificated Securities. Interests in the global new note will be exchanged
for certificated securities if (1) the Depository Trust Company notifies Verio
that it is unwilling or unable to continue as Depository Trust Company for the
global new note, or the Depository Trust Company ceases to be a "clearing
agency" registered under the Exchange Act, and a successor Depository Trust
Company is not appointed by Verio within 90 days, or (2) an Event of Default has
occurred and is continuing with respect to the new notes. Upon the occurrence of
any of the events described in the preceding sentence, Verio will cause the
appropriate certificated securities to be delivered.
 
                   MATERIAL FEDERAL INCOME TAX CONSIDERATIONS
 
     The following discussion summarizes the material federal income tax
consequences that apply to the exchange of old notes for new notes and the
ownership and disposition of the new notes. It is based on the Internal Revenue
Code of 1986, as amended, applicable U.S. Treasury Regulations, judicial
authority, and administrative rulings and practice, as of the date of this
exchange offer. The discussion below does not address any state, local or
foreign tax consequences of an exchange of old notes for new notes, or of
ownership and disposition of the new notes. Your tax treatment may vary
depending upon your particular situation. You may also be subject to special
rules not discussed below if you are a certain kind of note owner, including:
 
     - an owner which did not purchase the old notes for cash at original issue;
 
     - a financial institution or broker-dealer;
 
     - an insurance company;
 
     - a tax-exempt organization; or
 
     - a holder of a note as part of a hedge, straddle or conversion
       transaction.
 
     The following discussion assumes that you hold your old notes as capital
assets at the time of the exchange and will hold your new notes as capital
assets.
 
     The tax law upon which this discussion is based is subject to change at any
time, and any change may be applied retroactively in a manner that could
adversely affect you. In addition, Verio has not requested an advance ruling
from the Internal Revenue Service as to the tax consequences of the exchange
offer. The Internal Revenue Service could take different positions concerning
the tax consequences of the exchange offer
 
                                       121
<PAGE>   122
 
and the tax consequences of ownership and disposition of the new notes discussed
below and such positions could be sustained.
 
     The tax consequences to you of the exchange offer and of ownership and
disposition of the new notes may depend upon whether you are a "U.S. holder."
You are a "U.S. holder" if you are a beneficial owner of notes who or that is:
 
     - a citizen or resident of the United States;
 
     - a corporation, partnership or other legal entity created or organized in
       or under the laws of the United States or one of its political
       subdivisions;
 
     - an estate, if your income is subject to U.S. federal income taxation
       regardless of its source;
 
     - a trust if (A) a U.S. court is able to exercise primary supervision over
       your administration and (B) one or more U.S. persons (as defined in
       Section 7701(c)(30) of the Internal Revenue Code) has authority to
       control all of your substantial decisions; or
 
     - otherwise subject to U.S. federal income tax on a net income basis with
       respect to the new notes.
 
     If you are not a U.S. holder under these rules, you should review the
discussion below with respect to ownership of the new notes by a non-U.S.
holder.
 
     WE STRONGLY URGE YOU TO CONSULT WITH YOUR OWN TAX ADVISOR REGARDING THE
PARTICULAR TAX CONSEQUENCES OF THE EXCHANGE OFFER TO YOU, AND REGARDING YOUR
PARTICULAR TAX CONSEQUENCES IN OWNING AND DISPOSING OF THE NEW NOTES, INCLUDING
THE EFFECT OF U.S. FEDERAL ESTATE AND GIFT TAX LAWS, AS WELL AS WITH RESPECT TO
THE EFFECT OF ANY FOREIGN, STATE, OR LOCAL LAWS APPLICABLE TO YOU.
 
EXCHANGE OFFER
 
     Your exchange of old notes for new notes in the exchange offer will not be
treated as a taxable event for U.S. federal income tax purposes because the old
notes do not differ materially in kind or extent from the new notes. Your new
notes will be treated as a continuation of the old notes. You will have the same
tax basis and holding period in the new notes as you had in the old notes
immediately before the exchange.
 
OWNERSHIP AND DISPOSITION OF NEW NOTES BY U.S. HOLDERS
 
     Taxation of interest. Stated interest on your new notes generally will be
taxable to you as ordinary income at the time it is paid or accrued, depending
on your method of accounting for federal income tax purposes. The new notes are
not expected to give rise to "original issue discount" to you.
 
     Sale or redemption of a new note. You will recognize gain or loss upon the
sale, retirement, redemption or other taxable disposition of your new note. The
amount of gain or loss will be equal to the difference between the amount of
cash and the fair market value of other property you receive (except for cash or
other property attributable to accrued but unpaid stated interest), and your
adjusted tax basis in the new note. The gain or loss will be capital gain or
loss. However, you should know that a purchaser of a new note from you may be
subject to the "market discount" rules, discussed below.
 
     Under the "market discount" rules of the Internal Revenue Code, someone who
purchases a new note from you at a discount generally will be required to
include as ordinary income a portion of any gain realized upon the subsequent
disposition or retirement of the new note equal to the amount of the market
discount the purchaser has not previously included in income.
 
                                       122
<PAGE>   123
 
OWNERSHIP AND DISPOSITION OF NEW NOTES BY NON-U.S. HOLDERS
 
     U.S. withholding and income tax. You will not be subject to U.S.
withholding tax on interest payments on the new notes provided:
 
     - you do not actually or constructively own 10% or more of the total
       combined voting power of all classes of Verio stock;
 
     - you are not a controlled foreign corporation for U.S. federal income tax
       purposes that is related to Verio through stock ownership;
 
     - you are not a bank that received the old note on an extension of credit
       made pursuant to a loan agreement with Verio entered into in the ordinary
       course of your trade or business; and
 
     - you provide a statement to Verio signed under penalties of perjury that
       includes your name and address and you certify that you are not a United
       States person, as required by applicable tax regulations.
 
     If you cannot meet these requirements, you generally will be subject to
U.S. withholding tax at a rate of 30% on interest payments, unless you are
eligible for a reduced withholding tax rate under a U.S. tax treaty.
 
     If you are engaged in a trade or business in the United States, and the
interest paid or accrued on the new note is effectively connected with your
conduct of that trade or business, you will be subject to federal income tax on
the interest to the same extent as if you were a U.S. holder. However, you will
not be subject to withholding tax if you provide a properly completed Internal
Revenue Service Form 4224 to Verio.
 
     Sale or retirement of a new note. Any gain realized by you on a sale,
exchange, or redemption of a new note will not be subject to U.S. withholding or
income tax unless the gain is effectively connected with your conduct of a trade
or business in the United States or you are an individual who is present in the
United States for 183 days or more during the taxable year in which you realize
the gain and certain other conditions are satisfied.
 
     U.S. estate tax. If you hold the new notes at the time of your death, the
new notes generally will not be includible in your estate for U.S. estate tax
purposes. However, the new notes will be included in your estate if, at the time
of your death, you owned, actually or constructively, 10% or more of the total
combined voting power of all classes of Verio stock or if the new notes were
effectively connected with your conduct of a trade or business in the United
States.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     If you are a U.S. person and are not a corporation, you may be subject to
information reporting to the Internal Revenue Service with respect to the new
notes. You may also be subject to backup withholding at a rate of 31% on
payments of principal and interest on the new notes, and on the proceeds from
disposition of the new notes. However, backup withholding will be imposed on you
only if:
 
     - you fail to furnish to Verio your taxpayer identification number, which,
       if you are an individual, is normally your social security number;
 
     - you furnish to Verio an incorrect taxpayer identification number;
 
     - you are notified by the Internal Revenue Service you have failed to
       properly report the receipt of interest or dividend income; or
 
     - under certain circumstances, you fail to certify to Verio, under
       penalties of perjury, that you have furnished Verio a correct taxpayer
       identification number and that you have not been notified by the Internal
       Revenue Service that you are subject to backup withholding.
 
     Verio will also start backup withholding if the Internal Revenue Service
instructs it to do so.
 
     You should consult your own tax advisor to determine whether you may
qualify for an exemption from information reporting or backup withholding and
the procedure for obtaining an exemption.
 
                                       123
<PAGE>   124
 
     If you certify to Verio that you are a non-U.S. holder, you will not be
subject to information reporting or backup withholding with respect to payments
of interest on the new notes unless Verio has actual knowledge that you are a
U.S. holder.
 
     If you dispose of the new notes to or through the U.S. office of any
broker, you will be subject to information reporting and you may be subject to
backup withholding unless you certify to the broker that you are a non-U.S.
holder or that you otherwise are exempt from information reporting or backup
withholding. You will also be subject to information reporting and may be
subject to backup withholding if the broker has actual knowledge that you are a
U.S. holder or that the conditions of your claimed exemption are not satisfied.
 
     If you dispose of the new notes to or through a non-U.S. office of a
non-U.S. broker that is not a "U.S. related person" you will not be subject to
information reporting or backup withholding. For this purpose, a "U.S. related
person" is a corporation which is a "controlled foreign corporation" for U.S.
income tax purposes, or a foreign person, 50% or more of whose gross income from
all sources for the 3-year period ending with the close of its taxable year
preceding the payment, or the period of the person's existence, if less than 3
years, is derived from activities that are effectively connected with the
conduct of a U.S. trade or business.
 
     If you dispose of the new notes to or through a non-U.S. office of a broker
that is a U.S. related person, information reporting will be required unless the
broker has documentary evidence in its files that you are a non-U.S. holder and
the broker has no knowledge to the contrary. However, backup withholding will
not apply to these payments unless the broker has actual knowledge that you are
a U.S. holder.
 
     If a payment to you is subject to backup withholding, you will be allowed a
credit for the amount withheld against your U.S. income tax liability for the
year, or you may obtain a refund of the withheld amount if no tax is due and you
follow the necessary procedures for claiming a refund.
 
PROSPECTIVE TAX REGULATIONS AFFECTING NON-U.S. HOLDERS
 
     In 1997, the Internal Revenue Service published new regulations to modify
the requirements imposed on non-U.S. holders and certain intermediaries to
establish the status of the holder as a non-U.S. holder eligible for exemption
from or reduction in U.S. withholding tax and from the backup withholding rules.
The new regulations generally will be effective for payments made after December
31, 1999, subject to certain transition rules. In general, the new regulations
do not significantly alter the substantive withholding and information reporting
requirements. Rather, they unify 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 certification on behalf of non-U.S. holders. Under the new
regulations, an intermediary may be required to enter into an agreement with the
Internal Revenue Service to audit certain documentation with respect to such
certifications. You should consult your own tax adviser to determine the effects
of the application of the new regulations to your particular circumstances.
 
                              PLAN OF DISTRIBUTION
 
     Each broker-dealer that receives new notes for its own account in the
exchange offer must acknowledge that it will deliver a prospectus in connection
with any resale of 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. Verio has agreed that, starting on the expiration date and ending
180 days after the expiration date, it will make this prospectus, as amended or
supplemented, available to any broker-dealer for use in connection with any
resale. In addition, until such date, all dealers effecting transactions in the
new notes may be required to deliver a prospectus.

<PAGE>   125
 
     Verio 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 in the exchange offer may be sold from time to time in one or more
transactions:
 
     - in the over-the-counter market, in negotiated transactions;
 
     - through the writing of options on the new notes; or
 
     - a combination of such methods of resale.
 
     They can be sold 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 in the exchange offer 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. Any profit or commissions received by them from
any resale may be deemed to be underwriting compensation under the Securities
Act. The letter of transmittal states that by acknowledging that it will deliver
and by delivering a prospectus, a broker-dealer will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act.
 
     For a period of 180 days after the expiration date, Verio will promptly
send additional copies of this prospectus, including any amendment or
supplement, to any broker-dealer that requests such documents in the letter of
transmittal. Verio has agreed to pay all expenses incident to the exchange
offer, 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 Verio by Morrison &
Foerster LLP, San Francisco, California.

                                   VERIO INC.
 
          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
 
     During the period from August 1, 1996 through March 31, 1999, Verio
completed numerous business combinations, whereby we acquired newly authorized
redeemable, convertible preferred stock, shares of common stock, or certain net
assets of entities operating in the Internet industry, and completed the buyout
of the remaining equity interests of certain Internet service providers in which
it initially acquired a less-than-100% equity position. 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. Business combinations completed in
1998 -- which we refer to as the 1998 acquisition -- are described in Note A to
the accompanying pro forma condensed combined financial statements. In addition,
on January 5, 1999, we completed the acquisition of a 100% interest in the
outstanding common stock of Hiway Technologies, Inc., including Hiway's 20%
interest in WWW-Service Online-Dienstleistungen AG in which Verio purchased an
80% interest during 1998. This acquisition also has been accounted for using the
purchase method of accounting. The Hiway acquisition is also described in Note A
to the pro forma condensed combined financial statements. The Company also
completed other acquisitions, which were not considered to be significant and,
accordingly, have not been included in the accompanying pro forma financial
statements.
 
     While Verio now seeks to acquire 100% of new businesses, our early
acquisition strategy was to rapidly build mass and scale by acquiring less than
100% of our affiliates. In each case where we acquired less than 100% of an
affiliate initially, we 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 affiliate. As part of our integration strategy, we have
effected the buyouts of all but one affiliate in which it did not initially
acquire a 100% interest, through the use of cash on hand and the issuance of
equity. During the six months ended June 30, 1998, Verio consummated the buyout
of the following fifteen affiliates; 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., Clark Internet Services, Inc., Compute Intensive Inc., Structured Network
Systems, Inc. and Internet Online, Inc. Those buyouts in which Verio did not
previously own a majority interest on a fully diluted basis, are included in the
1998 acquisitions, as described in Note A. With respect to the buyout that has
not yet been completed, we have contractual rights to effect this buyout and
expect to complete the buyout during 1999. However, there can be no assurance
that Verio will be able to complete this buyout at the time, or in accordance
with the terms and conditions, that we currently contemplate. This acquisition
will also be accounted for using the purchase method of accounting.
 
     The assets and liabilities of the 1998 acquisitions and the Hiway
acquisition, adjusted for the application of the purchase method of accounting,
are included in the March 31, 1999 historical Verio consolidated balance sheet
included elsewhere in this prospectus. Accordingly, a March 31, 1999 pro forma
condensed combined balance sheet has not been presented. The unaudited pro forma
condensed combined statement of operations for the year ended December 31, 1998
assumes that the 1998 acquisitions and the Hiway acquisition had occurred on
January 1, 1998 and includes the historical consolidated statements of
operations of Verio and the acquired businesses for the year ended December 31,
1998, adjusted for the pro forma effects of the acquisitions. The Hiway
acquisition was completed on January 5, 1999 and accordingly, the pro forma
statement of operations for the three months ended March 31, 1999 would not be
significantly different from the historical results of operations. Therefore, a
pro forma statement of operations for this period has not been presented.
 
     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, 1998 and is
not intended to indicate the expected results for any future period. This
statement should be read in conjunction with the historical consolidated
financial statements and related notes of Verio, and certain acquired
businesses, included in this prospectus.

                          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, 1997 and 1998, and the related consolidated
statements of operations, stockholders' equity (deficit), and cash flows for the
period from inception (March 1, 1996) to December 31, 1996 and the years ended
December 31, 1997 and 1998. These consolidated financial statements are the
responsibility of Verio'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, 1997 and 1998, and the results of their
operations and their cash flows for the period from inception (March 1, 1996) to
December 31, 1996 and the years ended December 31, 1997 and 1998 in conformity
with generally accepted accounting principles.

                          VERIO INC. AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  (a) Organization and Basis of Presentation
 
     Verio Inc. (Verio or the Company) was incorporated on March 1, 1996 to
capitalize on the growing demand for Internet access and enhanced services by
business users through the acquisition, integration, and growth of existing
independent Internet service providers with a business customer focus in
targeted geographic regions. The goal of Verio is to be the dominant,
full-service national provider of Internet connectivity and enhanced Internet
services to small and medium sized businesses. Verio commenced operations in
April 1996 and had no activity other than the sale of common stock to founders
prior to April 1, 1996. Verio operates in one business segment and has
operations in the United States and Europe. International operations were not
significant in 1996, 1997, 1998, or for the three months ended March 31, 1999.
 
     The accompanying unaudited financial information as of March 31, 1999 and
for the three-month periods ended March 31, 1998 and 1999 has been prepared in
accordance with generally accepted accounting principles for interim financial
information. All significant adjustments, consisting of only normal and
recurring adjustments, which, in the opinion of management, are necessary for a
fair presentation of the results for the three months ended March 31, 1998 and
1999 have been included. Operating results for the three-month period ending
March 31, 1999 are not necessarily indicative of the results that may be
expected for the full year.
 
     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 amounts of revenue and expenses during
the reporting period. Actual results could differ from those estimates.
 
  (b) Cash and Cash Equivalents, Restricted Cash and Securities Available for
Sale
 
     Verio 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, 1997 and 1998, and March 31, 1999 are U.S. government, municipal
and corporate debt securities, money market accounts and commercial paper
totaling $65,518,000 (exclusive of cash overdraft in the amount of $11,228,000),
$433,304,000 and $204,975,000, respectively, with maturities ranging from thirty
to ninety days. Verio's short-term investments consist of readily marketable
debt securities with remaining maturities of more than 90 days at time of
purchase. Verio has classified its entire investment portfolio as available for
sale. Available for sale securities are stated at fair value with unrealized
gains and losses included in stockholders' equity. At December 31, 1997 and
1998, and March 31, 1999, the amortized cost of these securities approximated
market value.
 
     Restricted cash and securities include U.S. government securities which are
considered to be securities held to maturity and recorded at cost. At December
31, 1997 and 1998, and March 31, 1999, 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.

                          VERIO INC. AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
  (d) Investments in Affiliates and Consolidation of Subsidiaries
 
     Investments in affiliates generally represent newly issued preferred shares
of various affiliates. The preferred shares are convertible at the option of
Verio into common shares on a one-for-one basis and represent future common
stock ownership interests, upon conversion, of less than 50%. As Verio 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, Verio 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 Verio's investment, based
on the inability of the majority common shareholders to fund additional losses.
During the year ended December 31, 1997, Verio recognized equity in losses of
affiliates of $1,958,000 under this method of accounting. Such losses were not
significant for the year ended December 31, 1998, or the three months ended
March 31, 1999.
 
     Verio has also acquired preferred shares in certain entities which are
convertible into future common stock ownership interests of greater than 50%. In
these situations, Verio 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. As of December 31, 1998, Verio had acquired a 100% ownership interest in
all but two affiliates. Accordingly, the accounts of these investees have been
consolidated with those of Verio 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. Debt issuance
costs are amortized over the life of the debt. Other assets consist primarily of
the costs associated with customer acquisitions and non-compete agreements and
are amortized over a three-year period.
 
  (f) Long-Lived Assets
 
     Verio evaluates the carrying value of its long-lived assets, including
goodwill, 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 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 and enhanced 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

  (h) Peering Relationships
 
     Verio does not pay any fees in connection with its peering relationships
with other companies and does not record revenue or expense in connection with
those arrangements. The nature of these relationships is that the parties share
the responsibility for communications that occur between their respective local
networks. These peering relationships are essentially exchanges of similar
productive assets rather than the culmination of an earnings process.
Accordingly, these arrangements are not reflected in the operations of Verio.
 
  (i) Income Taxes
 
     Verio 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.
 
  (j) Stock-Based Compensation
 
     Verio accounts for its stock-based 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).
Verio 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 years ended
December 31, 1996, 1997 and 1998.
 
  (k) 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). Under
SFAS 128, basic EPS excludes dilution for potential common stock 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. Basic and
diluted EPS are the same in 1996, 1997, 1998 and 1999, as all potential common
stock instruments are antidilutive.
 
(2) BUSINESS COMBINATIONS, INVESTMENTS IN AFFILIATES AND ASSET ACQUISITIONS
 
     During the period from inception (March 1, 1996) to December 31, 1996,
Verio completed seven business combinations and investments for cash and notes
payable. All of the acquisitions were accounted for using the purchase method of
accounting, and represent the acquisition of stock or net assets. Outstanding
stock options of acquired businesses were included in the determination of the
purchase prices based on fair values. For those businesses acquired and
consolidated, the results of operations for the acquired businesses

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
     For the three months ended March 31, 1998, on a pro forma basis, total
revenue would have increased to $30.0 million, net loss attributable to common
stockholders would have increased to $33.3 and loss per share would have
decreased to $7.50 due to the additional common stock issued pursuant to the
purchase agreement relating to the acquisition of Hiway.
 
     In January 1999, Verio completed the acquisition of all the outstanding
common stock of Best Internet Communications, Inc. (which does business as Hiway
Technologies, Inc.) for total consideration of approximately $244.4 million,
including $176.0 million in cash and approximately 4.9 million fully diluted
shares of common stock. In February 1999, Verio also completed the acquisition
of Web Communications, LLC for approximately $8.0 million in cash.
 
     Investment in affiliates at December 31, 1998 and March 31, 1999 represents
the Company's cost-based investments primarily in V-I-A Internet, Inc. and
NorthPoint Communications.
 
     Effective March 4, 1999, Verio entered into an agreement with America
Online, Inc. ("AOL"). Under this three-year agreement, Verio will purchase
advertising promotions from AOL to promote Verio's Web hosting and related
business-focused commerce products and services on AOL's four key U.S. on-line
media properties. Verio's promotional rights with respect to its Web hosting and
designated electronic commerce products and services are exclusive during this
period on these four specified sites. AOL also will transition its approximately
7,000 Prime Host and CompuServe Business Web hosting customers to Verio. Verio
agreed to make guaranteed payments totaling $42.5 million over the first two
years of the three-year term of the agreement, with AOL participating in future
revenue sharing under specified circumstances defined in the agreement. The
first payment of $17.5 million was made in March 1999. The $42.5 million of
consideration was allocated to prepaid marketing expense and a Web hosting
customer base. The allocation was based on the estimated fair values of the
components of the agreement.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
     Interest on the November 1998 Notes, at the annual rate of 11 1/4%, is
     payable semi-annually in arrears on June 1 and December 1 of each year,
     commencing June 1, 1999. The November 1998 Notes are senior unsecured
     obligations of Verio ranking equally in right of payment with all existing
     and future unsecured and senior indebtedness. The November 1998 Notes
     contain terms that are substantially similar to the March 1998 Notes and
     the 1997 Notes.
 
(b)  On March 25, 1998, Verio completed the private placement of $175.0 million
     principal amount of senior notes (the "March 1998 Notes"). The March 1998
     Notes are redeemable at the option of Verio commencing April 1, 2002. The
     March 1998 Notes mature on April 1, 2005. Interest on the March 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 March 1998
     Notes are senior unsecured obligations of Verio ranking equally in right of
     payment with all existing and future unsecured and senior indebtedness. The
     March 1998 Notes contain terms that are substantially similar to the 1997
     Notes. Verio used approximately $54.5 million of the proceeds plus accrued
     interest to repurchase $50.0 million principal amount of the 1997 Notes. As
     a result, Verio 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. This transaction resulted in an
     extraordinary loss of $10.1 million.
 
(c)  In June 1997, Verio completed a debt offering of $150.0 million, 13 1/2%
     Senior Notes due 2004 (the "1997 Notes") and warrants to purchase 2,112,480
     shares of common stock at $.01 per share, expiring on June 15, 2004, which
     were valued at approximately $12.7 million based on Verio'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
     was recorded as debt discount and is being amortized to interest expense
     using the interest method over the term of the 1997 Notes. Upon closing,
     Verio 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 $13.1 at December 31,
     1998. The 1997 Notes are redeemable on or after June 15, 2002 at 103% of
     the face value, decreasing to face value at maturity. 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 at December
31, 1998 are as follows (in thousands):

     Rent expense for the period from inception (March 31, 1996) to December 31,
1996 and the years ended December 31, 1997 and 1998 was $128,000, $1,856,000,
and $4,048,000, respectively. Rent expense was $1,795,000 for the three months
ended March 31, 1999.
 
     In addition, Verio has entered into agreements with three
telecommunications companies to provide Verio with products and services to be
used in its operations.
 
     On March 31, 1998, Verio entered into a 15-year Capacity and Services
Agreement with Qwest Communications Corporation ("Qwest"), under which Verio
will have access to long haul capacity and ancillary services on Qwest's
nationwide MacroCapacity(sm) Fiber Network. The Capacity and Services Agreement
was amended on December 17, 1998 (as amended, the "Capacity Agreement"). Over
the first ten years of the term of the Capacity Agreement (the "Commitment
Term"), Verio must purchase, and Qwest must provide, not less than $160.0
million, in the aggregate, of such capacity and services (the "Commitment"), at
agreed upon prices. Additionally, Verio has the right to prepay its minimum
commitment under this contract. If prepaid, such capitalized costs would be
amortized to operations over the term of the agreement. The amount of the
prepayment available at December 31, 1998 was approximately $84.1 million. The
amount of capacity represented by the Commitment would satisfy less than 50% of
Verio's currently projected long haul capacity requirements over the Commitment
Term. However, Verio has the right to order capacity and services in excess of
the Commitment during the term of the Capacity Agreement, and after the
expiration of the Commitment Term, at the same prices.
 
     Under the second agreement, Verio is obligated to spend a total of $39
million between June 16, 1997 and June 16, 2002 of which approximately $3.7
million had been paid as of December 31, 1998. Annual payments will be based on
actual usage by Verio.
 
     Under the third agreement, Verio is obligated to spend $0.5 million during
1999.
 
     Verio had an outstanding irrevocable letter of credit in the amount of $1.4
million as of December 31, 1998 and March 31, 1999. 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 Verio'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 approximately $1.5 million secures the letter of credit.
 
     The Company is subject to litigation and claims incidental to its business.
While it is not feasible to predict or determine the financial outcome of these
matters, management does not believe they should result in a materially adverse
effect on the Company's financial position, results of operations or liquidity.
 
(5) PREFERRED STOCK
 
     Series A, B and C preferred shares were issued at $3, $6 and $8 per share
for total proceeds of $18,100,001, $60,170,004 and $20,000,000, respectively, in
1996 and 1997. The Series A, B, and C preferred shares were subject to mandatory
redemption and were convertible into common stock, initially on a one-for-one
basis. In December 1997, Verio also issued 680,000 shares of Series D-1
preferred stock at $15 per share in connection with an acquisition. The Series
D-1 preferred shares were not redeemable. From January 1, 1998 through April 30,
1998, Verio issued 1,534,513 additional shares of Series D-1 preferred stock
with values ranging from $15 to $22 per share in connection with business
combinations. In connection with Verio's initial public offering of common stock
discussed in note 6, all outstanding preferred shares were converted to common
stock in May 1998. At December 31, 1998 and March 31, 1999, no preferred shares
were issued and outstanding. The Board of Directors have the authority to issue
from time to time up to 12,500,000 shares of undesignated preferred stock.
 
(6) STOCKHOLDERS' EQUITY
 
  Common Stock Offerings
 
     On May 15, 1998, Verio completed its initial public offering of common
stock. Verio issued 5,735,000 shares for net proceeds, after offering costs, of
approximately $120.8 million.
 
     Concurrent with the above offering, Verio also sold an additional 4,493,877
shares to a strategic investor for total proceeds of approximately $100.0
million.
 
  Stock-Based Compensation Plans
 
     Verio has established Incentive Stock Option Plans (the Plans) whereby, at
the discretion of the Board of Directors (the Board), Verio may grant stock
options to employees of Verio and its controlled subsidiaries. As of December
31, 1998, Verio had reserved 6,601,349 shares for issuance under the Plans.
Prior to Verio's initial public offering, the option price was determined by the
Board at the time the option is granted, with such price being not less than the
fair market value of Verio's common stock at the date of grant, as determined by
the Board. Options granted subsequent to the initial public offering are granted
at fair value based on quoted prices for Verio's common stock. As of December
31, 1998 options had been granted entitling the holders to purchase 6,601,349
shares of Verio's common stock, at exercise prices ranging from $1 to $30.06 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 Verio'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. Options may be
exercised prior to their scheduled vesting date, but are subject to a repurchase
by Verio at the exercise price until the scheduled vesting date.

     During the period and years ended December 31, 1996, 1997 and 1998, the per
share weighted-average fair value of stock options granted was $.46, $1.08 and
$11.54, respectively, on the date of grant using the Black-Scholes
option-pricing model with the following weighted-average assumptions: no
dividends, volatility of 0% in 1996 and 1997 and 95% in 1998, risk-free interest
rate of 6%, and expected life of three years. If Verio had recorded compensation
expense for the period and years ended December 31, 1996, 1997 and 1998, based
on the fair value of the options at the grant date under SFAS No. 123, net loss
attributable to common stockholders would increase to $5,210,000, $46,737,000
and $137,248,000, respectively, and basic and diluted net loss per common share
would increase to $5.36, $40.83 and $6.42, respectively.
 
     Since inception, Verio has generally granted stock options with exercise
prices equal to the fair value of the underlying common stock, as determined by
Verio's Board of Directors and based on Verio's other equity transactions prior
to the initial public offering, and quoted prices of Verio's common stock
thereafter. Accordingly, Verio had not recorded compensation expense related to
the granting of stock options in 1996, 1997 and through February 28, 1998.
Subsequent to February 28, 1998, Verio granted options to employees with
exercise prices less than the fair value per share based upon Verio's estimated
price per share in the initial public offering. Accordingly, Verio will record
compensation expense totaling approximately $8.2 mil-

lion, as adjusted for forfeitures, pro rata over the forty-eight month vesting
period of the options. This compensation expense totaled approximately $1.9
million and $0.5 million for the year ended December 31, 1998 and the three
months ended March 31, 1999, respectively. In addition, Verio incurred $1.4
million in compensation expense during the year ended December 31, 1998 related
to accelerated vesting of options and approximately $0.6 million in compensation
expense related to options issued to Verio's new president.

</TABLE>
 
     The components of deferred tax assets as of March 31, 1999 were not
significantly different from the amounts as of December 31, 1998.
 
     At December 31, 1998, Verio has a net operating loss carryforward for
federal income tax purposes of approximately $133.1 million, which is available
to offset future federal taxable income, if any, through 2018. As a result of
various equity transactions during 1996, 1997 and 1998, management believes
Verio 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 Verio in 1996, 1997, 1998 or 1999 and a valuation allowance
has been recorded for the entire amount of Verio's deferred tax asset.
 
(8) CONCENTRATION OF CREDIT RISK AND FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     Financial instruments that potentially subject Verio to concentrations of
credit risk consist primarily of cash, cash equivalents and accounts receivable.
As of December 31, 1996, 1997, 1998, and March 31, 1999, Verio had no
significant concentrations of credit risk. Concentrations of credit risk with
respect to trade receivables are limited due to the large number of customers
comprising Verio's customer base and the relatively minor balances of each
individual account. At December 31, 1996, 1997, 1998, and March 31, 1999, the
fair values of Verio's financial instruments approximate their carrying value,
based on their terms and interest rates and quoted market prices.
 
(9) EMPLOYEE BENEFIT PLAN
 
     Verio has a 401(k) Plan (the Plan) for all full time employees of Verio.
Verio may make discretionary contributions to the Plan on behalf of employees
that meet certain contribution eligibility requirements defined under the terms
of the Plan. Verio did not make any contributions to the Plan during 1996, 1997
or 1998.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Verio Inc.:
 
     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 ended December 31, 1996
and 1997 and the period from January 1, 1998 to February 27, 1998. 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 ended December 31, 1996 and 1997 and the period from January 1, 1998 to
February 27, 1998 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
value, less costs to sell.
 
  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.
 
  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
 
                                      F-35

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
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 California 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.
 
(2) EQUIPMENT
 
     Equipment consisted of the following at December 31:

                         NOTES TO FINANCIAL STATEMENTS
                               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.

The Board of Directors
Verio Inc.:
 
     We have audited the accompanying balance sheet of STARnet, L.L.C. as of
December 31, 1997 and the related statements of operations, members' equity and
cash flows for the year ended December 31, 1997 and the period from January 1,
1998 to April 14, 1998. 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 STARnet, L.L.C. as of
December 31, 1997, and the results of its operations and its cash flows for the
year ended December 31, 1997 and the period from January 1, 1998 to April 14,
1998 in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1997
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization and Basis of Presentation
 
     STARnet, L.L.C. (the Company) was originally organized as a limited
liability company in the State of Missouri as Internetix, L.L.C. on June 21,
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.
 
     Effective April 14, 1998, the net assets of STARnet, L.L.C. were acquired
by Verio Inc.
 
  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.
 
(2) EQUIPMENT
 
     Equipment consisted of the following at December 31, 1997:

The Board of Directors
Verio Inc.:
 
     We have audited the accompanying balance sheets of Computing Engineers Inc.

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 Computing Engineers Inc. as

                           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.
 
     Effective April 15, 1998, the net assets of Computing Engineers Inc. 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.
 
  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
 
                                      F-58

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.

We believe that our audits provide a reasonable basis for our opinion.

                         NOTES TO FINANCIAL STATEMENTS
                      APRIL 30, 1997 AND 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.
 
     Effective April 30, 1998, the net assets of LI Net, Inc. 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.
 
  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
 
                                      F-65

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.

bear interest at the bank's prime lending rate plus 2% (10.5% at January 31,
1997) and are due in 1998.

of approximately $392,000 for federal income tax purposes which will expire in

the related deferred tax asset due to the uncertainty relating to the
realization of the net operating loss carryforward in the future.

                         NOTES TO FINANCIAL STATEMENTS
                                 JUNE 30, 1998
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
ORGANIZATION AND BASIS OF PRESENTATION
 
     NTX, Inc. d/b/a TABNet (the Company), was incorporated as a subchapter S
Corporation in the State of California on November 24, 1997. Prior to
incorporation as a subchapter S Corporation, the Company was operating as NTX,
L.L.C., a limited liability corporation. All assets and liabilities of the
L.L.C. were contributed to the Company upon incorporation and recorded at
historical cost. The Company provides web hosting and domain name registration
services to customers primarily in the United States.
 
     Effective July 7, 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 revenue and expenses during the
reporting period. Actual results may differ from those estimates.
 
RESTRICTED CASH
 
     Restricted cash represents the retained portion of customer payments by the
Company's credit card merchant bank processors and is restricted for a period of
approximately six months after each payment transaction.
 
EQUIPMENT AND LEASEHOLD IMPROVEMENTS
 
     Equipment and leasehold improvements are recorded at cost, less accumulated
depreciation. Depreciation is recorded 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. 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 (Statement No. 121). Statement No. 121 requires impairment losses to be
recognized 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 their fair
value. Assets to be disposed of are reported at the lower of the carrying amount
or fair value, less costs to sell.
 
REVENUE RECOGNITION
 
     Web hosting and domain name registration revenue is recognized as the
services are provided. Set-up fees are recognized when installation is
completed. The Company records deferred revenue for accounts billed and/or
collected in advance.
 
INCOME TAXES
 
     No provision for income taxes has been included in the accompanying
financial statements for the nine months ended June 30, 1998 due to the
Company's status as a limited liability corporation and subchapter S
Corporation. Accordingly, net losses for the period were included in the
respective individual tax returns of the members and stockholders.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
STOCK-BASED COMPENSATION
 
     The Company accounts for its stock-based employee compensation 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 no options outstanding at June 30, 1998, and no formal
stock option plan in place. The Company will provide the pro forma disclosures
of net loss as if the fair value based method of accounting for the stock-based
compensation, as prescribed by Statement of Financial Accounting Standards No.
123, Accounting for Stock-Based Compensation (SFAS 123), had been applied, in
the future as applicable.
 
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 June 30, 1998 approximate their carrying amounts
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 AND LEASEHOLD IMPROVEMENTS
 
     Equipment and leasehold improvements consisted of the following at June 30,
1998:

</TABLE>
 
(3) STOCKHOLDERS' DEFICIT
 
     During the nine months ended June 30, 1998, the Company granted rights to
acquire a specific percentage ownership in the Company to four employees as
compensation. The Company recorded stock-based compensation expense of
$3,640,000 which, in the opinion of the Company's Board of Directors,
represented fair value at the date of grant based on the per share price paid by
Verio Inc. in the acquisition of the Company's common stock.
 
(4) COMMITMENTS
 
     The Company leases its facilities under long-term operating leases expiring
at various dates through 2003. Future minimum lease payments consist of the

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Verio, Inc.:
 
     We have audited the accompanying consolidated balance sheet of Best
Internet Communications, Inc. and subsidiaries as of December 31, 1998 and the
related consolidated statements of operations, shareholders' equity and cash
flows for the year then ended. These consolidated statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Best
Internet Communications, Inc. and subsidiaries as of December 31, 1998 and the
results of their operations and their cash flows for the year then ended in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1998
                      (IN THOUSANDS, EXCEPT SHARE AMOUNTS)
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     (A) BUSINESS AND BASIS OF PRESENTATION
 
     Best Internet Communications, Inc. (the Company) was incorporated in
California on September 21, 1994. The Company is a provider of Web hosting and
related enhanced Internet services to small and medium sized businesses. The
Company focuses on delivering high-quality, reliable and flexible services that
are backed by 24X7 customer support. On May 27, 1998, the Company merged with
Hiway Technologies, Inc. (Hiway Florida), a company based in Florida in a
business combination accounted for as a pooling of interests. Hiway Florida was
formed on April 6, 1995 and operated as an S corporation. On January 5, 1999,
all of the Company's outstanding common shares were acquired by Verio, Inc.
 
     The consolidated financial statements include the accounts of the Company
and its majority-owned subsidiaries. All significant intercompany balances and
transactions have been eliminated.
 
     The Company has minority investments in certain of its foreign resellers.
The activities of these entities are not significant.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
     (B) CASH AND CASH EQUIVALENTS
 
     The Company considers all highly liquid investments purchased with
maturities of three months or less to be cash equivalents.
 
     (C) FINANCIAL INSTRUMENTS
 
     Carrying amounts of certain financial instruments held by the Company
including cash and cash equivalents, accounts receivable, accounts payable and
other accrued liabilities approximate fair value due to their short maturities.
Based on borrowing rates currently available to the Company for debt with
similar terms, the carrying values of notes payable and capital lease
obligations approximate fair value.
 
     (D) INVENTORY
 
     Inventory is stated at the lower of cost (determined on a first-in,
first-out basis) or market, and consists primarily of third party equipment held
for resale.
 
     (E) EQUIPMENT AND LEASEHOLD IMPROVEMENTS
 
     Equipment and leasehold improvements is stated at cost and is depreciated
using the straight line method over estimated useful lives ranging from five to
seven years. Leasehold improvements are amortized over the term of the lease or
the estimated useful life of the asset, whichever is less. Major additions and
betterments are capitalized while replacements, maintenance, and repairs that do
not improve or extend the life of the assets are charged to expense.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     (F) LONG-LIVED ASSETS
 
     The Company evaluates the carrying value of its long-lived assets,
including goodwill, 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 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 amount or fair value, less costs to sell.
 
     Intangible assets consist of goodwill which is being amortized on a
straight-line basis over seven years.
 
     (G) REVENUE RECOGNITION
 
     Revenue consists primarily of Web hosting and Internet service fees, set-up
fees and equipment sales. The Company generally sells its Web hosting services
for contractual periods ranging from one to three months. Revenue from these
services is recognized ratably over the contractual period. The fee charged for
domain name reservations is recognized over the two year name reservation period
and any unrecognized portion of the revenue is booked upon any termination of
the reservation. Internet service fees consist of fixed monthly amounts that are
recognized as the service is provided. Payments received in advance of providing
services are deferred until the period such services are provided. Set-up fees
and equipment sales are recognized when the set-up services are performed. The
Company offers a 30-day money-back guarantee for Web hosting services. Refunds
made by the Company have not been significant.
 
     (H) PRODUCT DEVELOPMENT
 
     Product development expenses are charged to operations as incurred.
 
     (I) INCOME TAXES
 
     The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS 109).
Under SFAS 109, deferred tax assets and liabilities are determined based on
differences between financial reporting and tax bases of assets and liabilities
and are measured using the enacted tax rates and laws that will be in effect
when the differences are expected to affect taxable income. Valuation allowances
are established when, in management's estimate, there is uncertainty over the
recovery of deferred tax assets. The provision for income tax is comprised of
taxes payable for the current period, plus the net change in deferred tax
amounts during the period.
 
     (J) PRO FORMA NET INCOME
 
     To properly reflect the Company's pro forma net income, the net income of
Hiway Florida (see note 2), which was not subject to income taxes prior to the
merger with the Company due to its S corporation status, has been tax effected
and included as a pro forma adjustment to income tax expense in the accompanying
consolidated statement of operations. This adjustment was computed as if the
merged company had been a taxable entity subject to federal and state income
taxes for the full year at the marginal tax rates applicable in such periods.

(2) BUSINESS COMBINATION
 
     On May 27, 1998, the Company merged with Hiway Florida, a provider of Web
hosting services. Under the terms of the merger agreement, each share of Hiway
Florida common stock was exchanged for 4.1374 shares of the Company's common
stock. The Company issued approximately 21.8 million shares of common stock in
exchange for all the outstanding shares of Hiway Florida. The Company also
assumed and exchanged all options and warrants to purchase Hiway Florida stock
for options and warrants to purchase approximately 3 million shares of the
Company's common stock at the same exchange rate as the common stock. The
transaction was accounted for as a pooling of interests and, accordingly, the
Company's financial statements have been presented to include the results of
Hiway Florida for the entire year.
 
     Separate and combined results of operations for the year ended December 31,
1998 are as follows:

(3) BUSINESS RISKS AND CREDIT CONCENTRATION
 
     The Company operates in the intensely competitive Internet industry which
is characterized by rapid technological change, short product life cycles, and
heightened competition. Significant technological changes in the industry could
affect operating results adversely.
 
     Financial instruments that potentially subject the Company to
concentrations of credit risk are comprised principally of cash and cash
equivalents, trade accounts receivable, and other receivables and deposits. As
of December 31, 1998, the Company's cash and cash equivalents are deposited with
numerous domestic financial institutions. With respect to accounts receivable,
the Company's customer base is dispersed across many different geographic areas.
The Company monitors customers' payment histories and establishes reserves for
bad debts as warranted. In addition to individual customers, the Company also
provides Web hosting services to resellers, who in turn provide services to
their own customers.
 
(4) EQUIPMENT AND LEASEHOLD IMPROVEMENTS

        (a) The bank notes bear interest at 9.75% to 10% per annum and are
     repayable in equal monthly installments through October 2001. The bank
     notes are collateralized by the Company's assets and require the Company to
     comply with certain covenants including a minimum monthly quick ratio, a
     minimum tangible net worth, a maximum ratio of total liabilities to
     tangible net worth, a minimum monthly subscriber additions to
     disconnections ratio, and minimum cash requirements. At December 31, 1998
     the Company was out of compliance with the covenants, and, accordingly, the
     entire balance of the bank notes is classified as current. The Company also
     has a line of credit with this bank in the amount of $500. The line of
     credit bears interest at 1% above the bank's prime rate, and advances are
     limited to 75% of eligible accounts receivable. At December 31, 1998 the
     amount outstanding on the line of credit was $500. In connection with the
     acquisition by Verio Inc. the bank notes and line of credit were repaid.

     Unsecured Notes (the Notes) with detachable warrants to purchase 1,654,962
     shares of common stock. The warrants can be exercised for $3.02 per share,
     at any time after December 19, 1997. The Notes are uncollateralized and
     bear interest at 5% from December 19, 1997 until January 1, 2000 and then
     bear interest at 9% through maturity on December 31, 2002. Quarterly
     payments of interest only are due beginning March 31, 1998 with the
     outstanding principal balance due on December 31, 2002. The notes may be
     prepaid at the option of the Company, subject to certain conditions, at a
     premium of ten percent.
 
        In connection with the issuance of the Notes and warrants, the Company
     attributed a portion of the proceeds to the warrants, which was recorded as
     additional paid in capital and as debt discount thereby increasing the
     effective interest rate to 13.895% and increasing interest expense for the
     year ended December 31, 1998 to $558. The unamortized balance of debt
     discount at December 31, 1998 was $923.

(7) NOTES RECEIVABLE FROM SHAREHOLDERS
 
     Notes receivable from shareholders consist of loans made to shareholders in
connection with the exercise of options for the Company's common stock or to
purchase common stock. The loans are recourse to the personal assets of the
shareholders, and bear interest at rates from 2% above prime to 8.5%, and are
due at various dates through 2000.
 
     During 1997, the Company issued a warrant to purchase 1,160,166 shares of
common stock at $2.78 per share to a shareholder, as an incentive to the
shareholder to become Chairman of the Board of Directors, in return for a
promissory note in the amount of $280. The note bears interest at the prime rate
and is due in 2000. The exercise price of the warrant was in excess of the fair
market value of the Company's common stock at the date of issuance, as
determined by other equity transactions and an independent valuation.
 
(8) SHAREHOLDERS' EQUITY
 
     (A) PREFERRED STOCK
 
     In 1996, the Board of Directors designated 4,000,000 shares of the Serial

Company in July 1996 and March 1997 to independent third party investors.
Effective May 27, 1998, all of the outstanding shares of Series B preferred
stock were converted into 3,462,000 shares of common stock.

     (C) STOCK OPTIONS
 
     Under the Company's 1996 Stock Option Plan, as amended, (the Plan) the
Company could issue incentive options to employees at prices not lower than fair
market value at the date of grant, as determined by the Board of Directors.
Supplemental stock options (options that do not qualify as incentive stock
options) could be granted to employees, directors and consultants at prices not
lower than 85% of fair market value at the date of grant, as determined by the
Board of Directors. The Board also had the authority to set the term of the
options (no longer than ten years from date of grant). Options generally vest
over three to four years. Unexercised options expire at least 30 days after
termination of employment with the Company.
 
     In April 1998, the Board of Directors and the shareholders approved the
adoption of a 1998 Equity Incentive Plan (the 1998 Plan) which is the successor
to the 1996 Stock Option Plan. The Company has reserved a total of 4,000,000
shares of common stock for issuance under the Plan. In June 1998, the Board also
adopted the 1998 Directors Stock Option Plan and reserved a total of 600,000
shares of common stock for issuance thereunder. No additional options were
granted under these Plans prior to the Company's acquisition by Verio, Inc.
