     This prospectus supplement relates to the resale by some of our

                              SELLING STOCKHOLDERS

     This prospectus supplement covers 876,800 shares of our 6.75% Series A
convertible preferred stock, $0.001 par value per share, and the shares of our
common stock issuable upon conversion of the convertible preferred stock. These
shares represent a portion of the shares included in the table of selling
stockholders in the prospectus, dated February 11, 2000, under the category "Any
other holder of convertible preferred stock or future transferee from any such
holder". The shares are being offered and sold by the selling stockholders named
below, who either are being added as new selling stockholders to the table of
selling stockholders in the prospectus or are supplementing and/or updating
information previously included in such table.

     The following table sets forth certain information, received through May
30, 2000, with respect to the number of shares of convertible preferred stock
beneficially owned and to be registered, the number of shares of common stock
beneficially owned and/or to be owned upon conversion of the convertible
preferred stock, the percentage of common stock beneficially owned and/or to be
owned after conversion of the convertible preferred stock prior to this
offering, and the number of shares of common stock to be registered, by the
selling stockholders named below. The information is based on information
provided by or on behalf of the selling stockholders and, with regard to the
beneficial holdings of the selling stockholders, is accurate only to the extent
beneficial holdings information was disclosed to us by or on behalf of the
selling stockholders. Because the selling stockholders may offer all, some or
none of the convertible preferred stock or common stock, no estimate can be
given as to the amount or percentage of the convertible preferred stock or
common stock that will be held by the selling stockholders upon termination of
any of the sales.

(1) The name of selling stockholders and the number of securities held by
    selling stockholders may be amended subsequent hereto pursuant to Rule
    424(b)(3) of the Securities Act of 1933, as amended.

(2) Assumes that, for each selling stockholder, the aggregate number of shares
    of convertible preferred stock held by that selling stockholder is converted
    to common stock pursuant to a ratio of one convertible preferred stock equal
    to 1.03559763303 shares of common stock. This latter figure has been
    calculated by dividing the liquidation preference of $50.00 per share by the
    conversion price of $48.2813. The conversion price of $48.2813 represents
    the conversion price after taking into account and adjusting for our
    two-for-one stock split completed on August 20, 1999. Based upon the
    aggregate conversion, a cash payment will be made in lieu of any fractional
    interest.

(3) Unless otherwise indicated in the table or by footnote, all shares of common
    stock beneficially owned by the selling stockholders are shares issuable
    upon conversion of the convertible preferred stock. Percentage ownership is
    based on 90,426,154 shares of our common stock, representing 82,969,852
    total shares of our common stock issued and outstanding as of May 30, 2000
    plus 7,456,302 shares of our common stock to be issued if all of our
    convertible preferred stock converts to common stock pursuant to the
    conversion ratio in footnote 2 above. The percentage ownership does not
    include shares of common stock that may be issued by us as dividends on the
    convertible preferred stock or in exchange for funds in the deposit account.

(4) For purposes of this prospectus supplement, the amounts listed with regard
    to the selling stockholder under the categories relating to the number of
    shares of convertible preferred stock and common stock being registered
    represent amounts in addition to, and separate from, all such amounts listed
    in the prospectus, dated February 11, 2000, and/or the prospectus
    supplement, dated April 7, 2000, with regard to the same selling
    stockholder.

(5) The selling stockholder is a broker-dealer.

(6) As an affiliate of a broker-dealer, the selling stockholder purchased the
    securities being registered here for resale in the ordinary course of
    business and, at the time of the purchase of the securities registered here
    for resale, had no agreements, either directly or indirectly, with any
    person to distribute the securities.

(7) In addition to the shares registered here, AIG SoundShore Holdings Ltd.
    beneficially owns, as of May 30, 2000, 60,900 shares of our convertible
    preferred stock that it purchased in a transaction or transactions under the
    Securities Act of 1933, as amended, pursuant to the registration statement
    of which this prospectus supplement is a part.

(8) In addition to the shares registered here, AIG SoundShore Opportunity
    Holding Fund Ltd. beneficially owns, as of May 30, 2000, 56,800 shares of
    our convertible preferred stock that it purchased in a transaction or

    registration statement of which this prospectus supplement is a part.

(9) In addition to the shares registered here, AIG SoundShore Strategic Holding

         7,200,000 SHARES OF 6.75% SERIES A CONVERTIBLE PREFERRED STOCK

     This prospectus is being used in connection with offerings from time to
time by some of our stockholders. The selling stockholders collectively own the
following stock being registered here:

     - 7,200,000 shares of 6.75% Series A convertible preferred stock, par value
$0.001 per share;

     - shares of common stock issuable upon conversion of the convertible
preferred stock;

     - 411,476 shares of common stock issued upon the exercise of warrants that
we assumed on January 5, 1999; and

     - 50,000 shares of common stock we agreed to register on behalf of an
individual who sold his company to us.

     This prospectus also relates to shares of common stock that we may issue in
lieu of cash to pay dividends on the convertible preferred stock and shares of
common stock that we may issue for funds held in an account opened for the
benefit of the holders of the convertible preferred stock.

     We and/or our wholly-owned subsidiary, Verio, LLC, may also offer from time
to time up to 2,000,000 shares of our common stock, $0.001 par value per share.
Any offering we make will be in amounts, at prices and on terms that we will
determine at the time of offering.

     We will provide to you, where required, specific terms of any offering of
securities sold under this prospectus in a prospectus supplement.

     The selling stockholders will receive all of the net proceeds from the sale
of their shares. We will receive the net proceeds from the sale of common stock
that we and/or Verio, LLC decide to sell or that we decide to deliver in
exchange for funds held in the deposit account opened on behalf of the holders
of our convertible preferred stock. The registration of the shares on behalf of
the selling stockholders, however, does not necessarily mean that any of the
selling stockholders will offer or sell their shares.

     We do not intend to list the convertible preferred stock on any securities
exchange or have it quoted on any automated quotation system. The convertible
preferred stock is eligible for trading in the Portal Market of the National
Association of Securities Dealers, Inc. Our common stock is traded on the Nasdaq
National Market under the symbol "VRIO." On February 9, 2000, the last reported
sale price of our common stock was $65.125 per share.

before you decide to invest.

                           FORWARD-LOOKING STATEMENTS

     This prospectus includes "forward-looking statements," as such term is
defined in the Private Securities Litigation Reform Act of 1995. These
statements can be identified by the use of forward-looking terminology such as
"believes," "expects," "may," "will," "should," or "anticipates" or the negative
thereof or other variations thereon or comparable terminology, or by discussions
of strategy that involve risks and uncertainties. The safe harbor provisions of
the Securities Exchange Act of 1934, as amended, and the Securities Act of 1933,
as amended, apply to forward-looking statements made by us. These
forward-looking statements involve risks and uncertainties, including those
identified within "Risk Factors" beginning on page 2 and elsewhere in, or
incorporated by reference into, this prospectus. The actual results that we
achieve may differ materially from any forward-looking statements, due to such
risks and uncertainties. These forward-looking statements are based on current
expectations, and we assume no obligation to update this information. Readers
are urged to carefully review and consider the various disclosures made by us in
this prospectus, any subsequent prospectus supplement and in our other reports
filed with the Securities and Exchange Commission that attempt to advise
interested parties of the risks and factors that may affect our business.

                                  RISK FACTORS

     An investment in Verio involves a high degree of risk. In addition to the
other information included in this prospectus and any subsequent prospectus
supplement, you should carefully consider the following risk factors in
determining whether or not to purchase the securities offered under this
prospectus and any subsequent prospectus supplement. These matters should be
considered in conjunction with the other information included or incorporated by
reference in this prospectus or any subsequent prospectus supplement. This
Prospectus contains statements which constitute forward-looking statements
within the meaning of the Private Securities Litigation Reform Act of 1995.
These statements appear in a number of places in this Prospectus and include
statements regarding the intent, belief or current expectations of Verio, our
directors or our officers primarily with respect to the future operating
performance of Verio. Prospective purchasers of our securities are cautioned
that any such forward-looking statements are not guarantees of future
performance and involve risks and uncertainties, and that actual results may
differ materially from those in the forward-looking statements as a result of
various factors. The accompanying information contained in this Prospectus,
including the information set forth below, identifies important factors that
could cause such differences. See "Forward-Looking Statements".

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, and the nine months ended
September 30, 1999, we had losses of $(46.1) million, $(122.0) million and
$(137.5) million, respectively. Because we have a relatively short operating
history, there is little operating and financial data about us, which makes an
evaluation of our business operations and prospects more difficult. We have
experienced annual growth in revenue from approximately $2.4 million from the
period of our inception to December 31, 1996; to approximately $35.7 million in
1997; to approximately $120.7 million in 1998; and to approximately $185.4
million for the nine months ended September 30, 1999.

WE EXPECT CONTINUING LOSSES AND CANNOT ASSURE YOU THAT WE WILL BECOME PROFITABLE

     We expect to continue to operate at a net loss in the near term as we
continue to use significant amounts of cash for our acquisition and integration
efforts, 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;

     - the amount of our expenditures at the corporate and national level; and

     - potential regulatory developments that may affect our operations.

     In order to achieve profitability, Verio must develop and market products
and services that gain broad commercial acceptance. We cannot assure you that
our products and services will ever achieve broad commercial acceptance or that
we will achieve profitability. Although we have experienced significant growth
in revenues on an annual basis, this growth rate is not necessarily indicative
of future operating results. We cannot assure you that we will achieve or
sustain positive operating cash flow or generate net income in the future.

WE HAVE SUBSTANTIAL LIABILITIES WHICH MAY IMPACT OUR FUTURE OPERATIONS AND
AFFECT OUR ABILITY TO MEET OUR DEBT OBLIGATIONS

     We have substantial amounts of outstanding debt and other liabilities. At
September 30, 1999, our total long-term liabilities were approximately $694.2
million, representing 59% of our total capitalization. In addition, we completed
in November 1999 an offering of 10 5/8% Senior Notes due 2009 in the aggregate
principal amount of $400.0 million, which we refer to as the November 1999
Notes, and we have a $100.0 million revolving credit facility from a group of
financial institutions. We have not drawn any funds under 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 $54.4 million cash flow used by our operations for the
       nine months ended September 30, 1999, $43.2 million, or approximately
       79%, was used to pay interest on our debt. Of this amount, 16% was used
       for interest on the $100.0 million outstanding principal amount of
       13 1/2% Senior Notes due 2004 -- which we refer to as the 1997 Notes; 21%
       was used for interest on the $175.0 million outstanding principal amount
       of 10 3/8% Senior Notes due 2005 -- which we refer to as the March 1998
       Notes; 54% was used for interest on the $400.0 million outstanding
       principal amount of 11 1/4% Senior Notes due 2008 -- which we refer to as
       the November 1998 Notes; and 9% was used for interest on capital leases
       and other obligations. Interest on our debt continues to be a significant
       use of cash.

     - Covenants imposed under certain of our financing agreements limit our
       ability to pursue our business strategy, borrow additional funds to grow
       our business, acquire and dispose of assets, and make capital
       expenditures and may otherwise restrict our operations and growth.

     Our ability to meet our debt and other obligations and to reduce our total
debt depends on our future operating performance and on economic, financial,
competitive, regulatory and other factors. In addition, we may need to incur
additional indebtedness in the future. Many of these factors are beyond our
control. We believe that our existing current assets combined with working
capital from our operations, our existing credit facility, capital lease
financings and proceeds of future equity or debt financings will be adequate to
meet our existing financial obligations. We cannot assure you, however, that our
business will generate sufficient cash flow 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);

     - $18.2 million in annual interest on the March 1998 Notes;

     - $45.0 million in annual interest on the November 1998 Notes;

     - up to $24.3 million in annual dividends we may pay on our convertible
       preferred stock, plus any additional dividends owed thereon depending on
       certain contingencies, beginning in November 2000;

     - $42.5 million in annual interest on the November 1999 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 $100.0 million revolving credit facility may only be used if we meet
certain financial tests. Our credit facility and other debt instruments contain
customary covenants limiting our flexibility, including covenants limiting our
ability to incur additional debt, make liens, make investments, consolidate,
merge or acquire other businesses and sell assets, pay dividends and other
distributions, make capital expenditures

                                        3
<PAGE>   9

and enter into transactions with affiliates. Such covenants may make it
difficult for us to pursue our business strategies. Failure to comply with the
terms of the credit facility would entitle the secured lenders to foreclose on
certain of our assets, including the capital stock of our subsidiaries. The
secured lenders would be repaid from the proceeds of the liquidation of those
assets before the assets would be available for distribution to other creditors
and, lastly, to the holders of Verio's capital stock. Our ability to satisfy the
financial and other restrictive covenants may be affected by events beyond our
control.

IT IS UNLIKELY THAT INVESTORS WILL RECEIVE A RETURN ON OUR COMMON STOCK THROUGH
THE PAYMENT OF CASH DIVIDENDS

     We have never declared or paid cash dividends on our common stock and have
no intention of doing so in the foreseeable future. In addition, although we
have the option of paying dividends in cash, our ability to pay cash dividends
is substantially restricted under various covenants and conditions contained in
our debt instruments. In any event, under Delaware law we are permitted to pay
dividends on our capital stock only out of our surplus, or if we have no
surplus, out of our net profits for the year in which a dividend is declared or
for the immediately preceding fiscal year. Surplus is defined as the excess of a
company's total assets over the sum of its total liabilities and convertible
preferred stock plus the par value of its outstanding capital stock. At
September 30, 1999, we had a stockholders' equity of approximately $492.3
million. We have had a history of losses and expect to operate at a net loss for
the next several years. These net losses will reduce our stockholders' equity.
For the nine months ended September 30, 1999, we had a net loss attributable to
common stockholders of $137.5 million. We cannot predict what the value of our
assets or the amount of our liabilities will be in the future.

PAYMENT OF DIVIDENDS AND ADDITIONAL DIVIDENDS IN SHARES OF COMMON STOCK MAY NOT
RESULT IN STATED DIVIDEND YIELD

     In the event dividends or additional dividends, if any, on our convertible
preferred stock are paid in shares of common stock, the number of shares of
common stock to be issued on each dividend payment date will be determined by
dividing the total dividend and additional dividends, if any, to be paid on each
share of convertible preferred stock by the Market Value Amount, as defined
under "Description of the Series A Convertible Preferred Stock -- General," on
the record date for such dividend. If the market value applicable in determining
the Market Value Amount is higher than the market value for the common stock on
the dividend payment date and you sell at such lower price, your actual dividend
yield could be lower than the stated dividend yield on the convertible preferred
stock. In addition, you are likely to incur commissions and other transaction
costs in connection with the sale of such common stock.

THE CONVERTIBLE PREFERRED STOCK IS SUBORDINATED TO ALL OUR LIABILITIES

     In the event of bankruptcy, liquidation or reorganization of Verio, our
assets will be available to pay obligations on the convertible preferred stock
only after all indebtedness and other liabilities, including our existing senior
notes and all subsequent series of preferred stock of Verio which rank senior to
the convertible preferred stock, have been paid. There may not be sufficient
assets remaining to pay amounts due on any or all of the convertible preferred
stock then outstanding. While we consider the funds placed in the deposit
account to be the property of the purchasers of the convertible preferred stock
and not our property, in a bankruptcy proceeding, our creditors or a trustee in
bankruptcy could claim that those funds constitute property of our bankrupt
estate. If that were to occur, access to the funds in the deposit account by the
purchasers of the convertible preferred stock would be denied until all our
indebtedness had been paid in full. As of September 30, 1999, the convertible
preferred stock is junior in right of payment to $670.8 million total
indebtedness and other obligations of Verio, of which $2.0 million is attributed
to our subsidiaries. In addition, in November 1999, we completed the offering of
the November 1999 Notes in the aggregate principal amount of $400.0 million. As
a result, the convertible preferred stock is also junior in right of payment to
this indebtedness.

OUR EARNINGS HAVE BEEN INSUFFICIENT TO PAY OUR COMBINED FIXED CHARGES AND
PREFERRED STOCK DIVIDENDS

     Our earnings were insufficient to pay our combined fixed charges and
preferred stock dividends during those periods and by the amounts set forth in
the table below, although our combined fixed charges and preferred stock
dividends included substantial non-cash charges for depreciation, amortization
and non-cash interest expense on some of our debt:

                                                               EARNINGS    NON-CASH

Nine months ended September 30, 1999........................  $(137,537)   $94,779
</TABLE>

     We anticipate that earnings will be insufficient to cover our combined
fixed charges and preferred stock dividends for the next several years. In order
for us to meet our debt obligations, we will need to substantially improve our
operating results. We cannot assure you that our operating results will be of
sufficient magnitude to enable us to meet our debt and preferred stock
obligations. In the absence of such operating results, we could face substantial
liquidity problems and may be required to raise additional financing through the
issuance of debt or equity securities. We cannot assure you, however, that we
would be successful in raising such financing on acceptable terms or otherwise.

OUR CONVERTIBLE PREFERRED STOCK HAS NEVER BEEN PUBLICLY TRADED

     There has been no public trading market for the convertible preferred
stock. We do not intend to list the convertible preferred stock on any national
securities exchange. The convertible preferred stock is eligible for trading in
the Portal Market; however, no assurance can be given as to the liquidity of, or
trading market for, the convertible preferred stock. Accordingly, there can be
no assurance that any market for the convertible preferred stock will be
maintained. If an active market for the convertible preferred stock fails to
develop or be sustained, the trading price of such convertible preferred stock
could be materially adversely affected.

THE MARKET PRICE AND TRADING VOLUME OF OUR COMMON STOCK ARE VOLATILE

     The market price of our common stock has fluctuated significantly in the
past, and is likely to continue to be highly volatile. In addition, the trading
volume in our common stock has fluctuated, and significant price variations can
occur as a result. We cannot assure you that the market price of our common
stock will not fluctuate or decline significantly in the future. In addition,
the U.S. equity markets have from time to time experienced significant price and
volume fluctuations that have particularly affected the market prices for the
stocks of technology and telecommunications companies. These broad market
fluctuations may materially adversely affect the market price of our common
stock in the future. Such variations may be the result of changes in our
business, operations or prospects, announcements of technological innovations
and new products by competitors, new contractual relationships with strategic
partners by us or our competitors, proposed acquisitions by us or our
competitors, financial results that fail to meet public market analyst
expectations, regulatory considerations and domestic and international market
and economic conditions.

FUTURE SALES OF OUR COMMON STOCK IN THE PUBLIC MARKET COULD ADVERSELY AFFECT OUR
STOCK PRICE AND OUR ABILITY TO RAISE FUNDS IN NEW EQUITY OFFERINGS

     No prediction can be made as to the effect, if any, that future sales of
shares of common stock or the availability for future sale of shares of common
stock or securities convertible into or exercisable for our common stock will
have on the market price of common stock prevailing from time to time. Sale, or
the availability for sale, of substantial amounts of common stock by existing
stockholders under Rule 144, through the exercise of registration rights or the
issuance of shares of common stock upon the exercise of
                                        5
<PAGE>   11

stock options or warrants or the conversion of our convertible preferred stock,
or the perception that such sales or issuances could occur, could adversely
affect prevailing market prices for our common stock and could materially impair
our future ability to raise capital through an offering of equity securities.
See "Description of Capital Stock."

WE ARE SUBJECT TO ANTI-TAKEOVER PROVISIONS THAT COULD DELAY OR PREVENT AN
ACQUISITION AND COULD ADVERSELY AFFECT THE PRICE OF OUR COMMON STOCK

     Our certificate of incorporation and bylaws, certain provisions of Delaware
law and the certificate of designation governing the convertible preferred stock
may make it difficult in some respects to cause a change in control of Verio and
replace incumbent management. In addition, Nippon Telegraph and Telephone
Corporation has the right to designate a member of our board of directors and is
subject to certain standstill and other limitations on its ability to make
further acquisitions of our stock that could delay, defer or prevent a change of
control. The existence of these provisions may collectively have a negative
impact on the price of the common stock, may discourage third-party bidders from
making a bid for Verio, or may reduce any premiums paid to stockholders for
their common stock. In addition, the board of directors has the authority to fix
the rights and preferences of, and to issue shares of, our preferred stock,
which may have the effect of delaying or preventing a change in control of Verio
without action by our stockholders. See "Description of Capital
Stock -- Anti-Takeover Provisions."

WE MAY BE UNABLE TO RAISE ADDITIONAL FUNDS THAT WE WILL NEED TO REMAIN
COMPETITIVE

     We depend on a number of different financing sources to fund our growth and
continued losses from operations. However, we cannot assure you that we will be
able to raise such funds on favorable terms or at all. In the event that we are
unable to obtain such additional funds on acceptable terms or otherwise, 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 and data 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.

<PAGE>   12

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 the consolidation and
       integration of our acquired operations; and

     - general telecommunications services' performance and availability.

     We also have experienced seasonal variation in Internet use. Accordingly,
our revenue streams may fluctuate. 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.
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 pursue acquisitions and investments both in the U.S.
and internationally, our success is highly dependent on the growth of our
existing Internet access and Web 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. We may develop these further product and
distribution capabilities internally, but we primarily plan to form 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. Once implemented, we cannot assure you that any additional
service capabilities that we launch will achieve general commercial acceptance
or generate significant revenue, or that any particular distribution channels
will prove to be effective.

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. To integrate our newly acquired Internet operations
successfully, we must:

     - install and standardize adequate operational and control systems;

     - deploy standard equipment and telecommunications facilities;

                                        7
<PAGE>   13

     - 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 our managerial,
operating and financial 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.

     The key integration challenges we face in connection with our acquisitions
include:

     - 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 and operational benefits may not be realized;

     - in the course of integrating an acquired operation, we may discover facts
       or circumstances that we did not know at the time of the acquisition that
       adversely impact our business or operations, or make the integration more
       difficult or expensive;

     - integration efforts may divert our resources from our existing business;

     - standards, controls, procedures and policies may not be maintained;

     - employees who are key to the acquired operations may choose to leave; and

     - we may experience unforeseen delays and expenses.

WE FACE RISKS ASSOCIATED WITH ACQUISITIONS GENERALLY

     We expect to continue our acquisition and expansion strategy. 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.

     We have recorded all business acquisitions under the purchase method of
accounting. With the acquisition, on January 5, 1999, of Best Internet
Communications, Inc. (d/b/a Hiway Technologies, Inc.), which we refer to as
Hiway, we recorded gross goodwill totaling approximately $240.5 million, which
is being amortized over a ten-year period from the acquisition date. On July 13,
1999, we acquired all of the outstanding stock of Computer Services Group, Inc.
(which does business as digitalNATION) for $100.0 million in cash, the goodwill
associated with which is being 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.

                                        8
<PAGE>   14

THE FINANCIAL INFORMATION CONCERNING BUSINESSES WE ACQUIRE MAY BE INACCURATE

     A number 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 included in this
prospectus or incorporated by reference 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.

OUR RAPID GROWTH PUTS A SIGNIFICANT STRAIN ON OUR RESOURCES

     As a result of our acquisition strategy, we have been growing rapidly 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 the 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 place 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 FOR SALES OF OUR PRODUCTS AND
SERVICES

     We depend on third-party channel partners to stimulate demand for our
products and services both where we do not have a direct sales force and as an
alternative means for generating sales to customers. These channel partners
include computer and telecommunications providers, Internet companies and
portals, value-added resellers, original equipment manufacturers, systems
integrators, Web designers and advertising agencies. Many of our channel partner
distribution relationships involve untested or novel modes of distributing our
products and services, and not all of these channel partners have been
successful in meeting our objectives for generating additional sales of our
products and services. If we fail to gain commercial acceptance in certain
markets, channel partners may discontinue their relationships with us or we may
fail to achieve a return on our investment in certain channel partner
distribution arrangements. Conflicts may develop between our direct sales force
efforts and those of our channel partners as well as among different 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 or may require us to incur additional sales and
marketing expenses. 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

     We provide Web hosting services to customers in over 170 countries. For the
year ended December 31, 1998, and for the nine months ended September 30, 1999,
we estimate that approximately 10% of our total revenues was from international
operations. We expect to continue to expand in these and other international
markets. However, the rate of development and adoption of the Internet has been
slower outside the U.S., and the cost of transmitting data over the Internet
outside the U.S. has been
                                        9
<PAGE>   15

higher, which may adversely affect our ability to expand operations, and may
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, certain risks inherent in doing business on an international level
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, changes in existing foreign
laws or administrative practice relating to taxation, foreign exchange,
regulatory or other matters could adversely affect us. For example, the European
Union recently enacted its own privacy regulations. Future decisions, laws,
regulations and other activities regarding regulation and content liability may
significantly affect our business. 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 -- Service Online -- Dienstleistungen GmbH.

     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.

WE FACE A HIGH LEVEL OF COMPETITION IN THE INTERNET SERVICES INDUSTRY

     The tremendous growth and potential market size of the Internet access
market and the absence of substantial barriers to entry have attracted many new
start-ups as well as existing businesses from the telecommunications, cable and
technology industries. As a result, the market for Internet access and related
services is extremely competitive. We anticipate that competition will continue
to intensify as the use of the Internet grows. Current and prospective
competitors include:

     - other independent providers of Web hosting and other enhanced value
       Internet services;

     - national, regional and local Internet service providers;

     - global, national and regional long distance and local exchange
       telecommunications companies;

                                       10
<PAGE>   16

     - cable television companies;

     - direct broadcast satellite and wireless communications providers; and

     - on-line service providers.

     We believe that the following are the primary competitive factors in this
market:

     - a secure and reliable national network with sufficient capacity, quality
       of service and scalability to support continued growth;

     - a knowledgeable and effective sales force, and broad and effective
       distribution channels;

     - knowledgeable and capable technical support personnel, and prompt and
       efficient customer care services;

     - Internet system engineering and other technical expertise;

     - competitive prices;

     - timely introductions of new products and services;

     - sufficient financial resources; and

     - 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, many carriers are
integrating horizontally through acquisitions of or joint ventures with Internet
service providers, or by wholesale purchase of Internet access from Internet
service providers. 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 also creates further competitive pressure on our 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
services to our target business market. This may significantly affect the
pricing of our Internet access service offerings. Although we offer for sale
digital subscriber line services to business customers in a large number of
markets, there are numerous providers of digital subscriber lines competing with
these product offerings, and several providers have launched their services in
conjunction with Internet service providers, allowing those providers to offer
Internet access over digital subscriber lines circuits. These circuits, which
provide higher speed and lower latency Internet connections than a standard
dialup phone connection, compete with our dedicated connectivity offerings.

     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 and those relationships could place us at a significant competitive
disadvantage.

WE DEPEND UPON OUR NETWORK INFRASTRUCTURE

     Our success depends upon our ability to implement and expand our 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, 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 fires, earthquakes, severe
storms, power losses, 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 point 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 you 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 we have not, as a general matter, offered our customers
a service-level warranty, our customers are increasingly requiring that we
provide a standard service-level warranty for our services. Many of our
competitors have begun to do so. As a result, in order to remain competitive, we
now expect to implement a standard policy under which we offer such a warranty
to our customers. To the extent that we provide 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. In addition, 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, we inherited these warranty obligations.

     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
                                       12
<PAGE>   18

liability or limiting liability to a usage credit based upon the amount of time
that the system was down. We cannot assure you, 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

     We have implemented certain network security measures, such as limiting
physical and network access to our routers. Nonetheless, we cannot assure you
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 or 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 ensure 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 us 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, 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 are necessary in order to exchange traffic with other
Internet service providers without paying transit costs. The basis on which the
large national Internet service providers make peering available or impose
settlement charges is evolving. Recently, companies that 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. We may have to comply with increasing peering
requirements in order to maintain our peering relationships. Failure to maintain
peering relationships or establish new ones, if necessary, will increase our
operating expenses.

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;

                                       13
<PAGE>   19

     - 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 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 communication, 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 Internet access and services are not broadly accepted, our
business, financial condition and results of operations will be materially
adversely affected. In addition, the rate of development and adoption of the
Internet has been slower outside 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 you 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 you 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 you 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 results of
operations.

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, 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. This decision is on appeal and was recently argued before the
U.S. Court of Appeals for the Third Circuit. We are unable to predict the
outcome of this appeal. In addition, the Federal Trade Commission has adopted
final rules that are to become effective April 21, 2000, regarding the
Children's Online Privacy Protection Act's prohibition of unfair and deceptive
acts and practices in connection with the collection and use of personal
information from and about children on the Internet. The rules provide that Web
sites directed at children under 13 years of age must obtain verifiable parental
consent before collecting personal information from children and must take other
measures intended to safeguard children's privacy. Additional requirements may
be imposed on Web site operations relating to the use, dissemination and
collection of personal information, and proposals to enact federal and state
legislation addressing issues relating to Internet content and liability are
submitted regularly. 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 discontinue certain product or service offerings. Any of these
actions could have a material adverse effect on our business, financial
condition and results of operations.

     The law relating to the regulation and liability of Internet access
providers in relation to information carried or disseminated also is developing
in other countries. For example, the European Union has enacted its own data
privacy regulations, and Australia has imposed new obligations on Internet
service providers to block access to certain types of content. 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, regulations at the Federal Communications Commission
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. Additional laws and regulations 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

                                       15
<PAGE>   21

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
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
dialup 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 products and services that
we resell and certain components of our network infrastructure. The products and
services that we resell, and certain components that we require for our network,
are available only from limited sources. For example, we currently rely
primarily 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 WorldCom and MFS, who sell
products and services that compete with ours, also are our primary providers of
data communications facilities and network capacity. Northpoint Communications
and Covad Communications provide us with digital subscriber line services for
resale to our customers. We also are dependent upon local exchange carriers,
which often are our competitors, to provide telecommunications services and
lease physical space to us for routers, modems and other equipment. From time to
time we experience delays in the delivery and installation of telecommunications
services, which can lead to the loss of existing or potential customers or
delays in generating revenues from sales to customers. We cannot assure you
that, on an ongoing basis, we will be able to obtain third-party products and
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
third-party products and services would have a material adverse effect on our
business, financial condition and results of operations.

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. We cannot assure you that we will be successful in attracting and
retaining qualified executives and personnel. In addition, our employees may
voluntarily terminate their employment with us at any time. The loss of the
services of key personnel or our failure to attract additional qualified
personnel could have a material adverse effect on our business, financial
condition and results of operations.

OUR BUSINESS MAY BE ADVERSELY IMPACTED BY YEAR 2000 ISSUES

     The commonly referred to Year 2000 or Y2K issue results from the fact that
many computer programs and systems were developed without considering the
possible impact of a change in the century
                                       16
<PAGE>   22

designation that occurred on January 1, 2000. As a result, these programs and
systems use only two digits instead of four to identify the year in the date
field. Systems that do not properly recognize this date could generate wrong
data, calculate erroneous results, or fail if the issue was or remains
uncorrected. The Year 2000 problem is pervasive and complex, as virtually every
company's computer operations potentially could be affected in some way.

     We have identified two main areas of potential Y2K risk in our business:

     - our internal systems or embedded chips could be disrupted or fail, which
       could negatively impact our services and productivity; and

     - computer systems or embedded technology of third parties, such as our
       suppliers, vendors, customers, landlords, telecommunication service
       providers, outsource providers, and others could be disrupted or fail,
       and thereby adversely affect our operations.

     In order to evaluate the potential impact of the Y2K problem on our
business, and to help ensure that our network operations and services to our
customers were not and are not interrupted due to the Y2K problem, we undertook
an extensive inventory, assessment and remediation program to evaluate and
remediate the Y2K compliance status of our equipment, network and systems. We
established a Y2K assessment team that was responsible for overseeing this
effort.

     Verio assessed the compliance status of all potentially affected systems
and equipment, identified from the inventory phase of our Y2K compliance effort,
throughout our operations. Compliance status was checked against third party
information sources including public statements made by hardware and software
vendors, correspondence directly with such vendors, and compilations of
compliance information published by other parties. Verio did not independently
verify compliance of such hardware and software components utilized within our
service or independently verify the contents of the republications.

     We believe that, as a result of our detailed assessment and remediation
efforts, the Y2K issue has not posed significant operational problems for us.
However, if Y2K compliance problems have not been discovered, or if requisite
modifications or remedies have not been undertaken or made, it is possible that
the Y2K problem still could have a material impact on our operations. We cannot
currently estimate the magnitude of such a possible impact.

     Through the end of 1999, we surveyed, among others, critical vendors,
suppliers, customers and financial institutions for Year 2000 compliance. We
evaluated the Year 2000 preparedness of our telecommunications providers on
which we rely for the network services crucial to our business. In order to
reduce potential adverse impacts, we have maintained diverse providers for such
network services. However, failure of any one provider could still have a
material impact on Verio's operations. Our survey of our third party suppliers
indicates that many of them were still working on their own Year 2000 compliance
issues through the end of 1999. We are heavily dependent upon the veracity of
their testing and statements of compliance as we cannot replicate and
independently test the services supplied to us. Though most of these suppliers
indicated that their critical systems and technology were Year 2000 ready, at
this time we cannot estimate the effect, if any, that non-compliant systems
supplied by these entities could have on us. It is possible that the impact on
us could be material if one or more of these systems were not Y2K compliant at
the end of last year. We continue to work with each of these suppliers to obtain
the latest information on their compliance status to assist us in evaluating and
developing contingency plans. If any of our material third party suppliers or
vendors were not Y2K ready and their non-compliance causes a material disruption
to any of their respective businesses or services, our business, operations
and/or services could be materially and adversely affected.

     The most significant risks that the Y2K issues continue to present to us
include, without limitation, disruption, delay or cessation of operations. Other
potential adverse Y2K scenarios include the failure or impairment of software
that is provided by a third party and incorporated in one of our service
platforms as a result of a Y2K problem. In that case, the particular service
that the software supports could likewise become inoperable or perform
incorrectly. Further, in the event that third-party-supplied equipment
(including customer premise equipment) contains non-Y2K-compliant technology,
the systems, operations
                                       17
<PAGE>   23

or services supported by that equipment also could fail or be interrupted. Other
potential disruptions could include the interruption in delivery of key supplies
from vendors and other interruptions in the normal course of our operations.
Even though the date is now past January 1, 2000, and we have not experienced
any immediate adverse impact from the transition to the Year 2000, we cannot
provide assurance that, in the event that a failure does occur, our services
would not suffer degradation or complete failure without warning or remedy,
resulting in substantial potential expense.

     While our expenditures to date in our Year 2000 program efforts have not
been material, it is possible that the costs associated with our Y2K efforts
could increase if it is determined that additional resources are required or if
important operational or systems equipment must yet be remediated or replaced.
The total cost of our Y2K compliance program is funded through cash on hand and
we are expensing these costs, as appropriate. While the financial impact of
making all required systems changes or other remediation efforts cannot be known
precisely, it is not expected to be material to our financial position, results
of operations, or cash flows. We have not cancelled any principal information
technology projects as a result of our Y2K efforts, although we have rescheduled
and reprioritized some internal tasks in order to accommodate these efforts.

     While we believe that we have adequately addressed the Y2K issue, we cannot
assure you that our Y2K compliance effort has prevented every potential
interruption or failure, or that the cost and liabilities associated with the
Y2K issue will not materially adversely impact our business, prospects,
revenues, or financial position.

                                USE OF PROCEEDS

     We will not receive any proceeds from the sale of shares of our convertible
preferred stock and common stock by the selling stockholders or from the
issuance of common stock as dividends. To the extent that we determine to issue
shares of our common stock in exchange for funds held in the deposit account on
behalf of the holders of the convertible preferred stock, the net proceeds from
this issuance will not be in excess of the amount in the deposit account, the
aggregate amount of which as of November 11, 1999, was approximately $18.3
million. Unless otherwise indicated in a prospectus supplement, the net proceeds
from this sale or any sale of common stock by us and/or Verio, LLC will be added
to our general corporate funds and may be used for general corporate purposes.
These purposes include continuing the development and implementation of the
national backbone, customer care center, network operations center and billing
and accounting services and furthering our acquisition and investment strategy.
In that regard, we are continually evaluating possible acquisition and
investment opportunities to strategically expand our geographic scope and
product offering capabilities, and anticipate that we will undertake and
effectuate transactions from time to time following the date of this prospectus.
We continue to evaluate additional businesses for investment or acquisition and
are currently in negotiations with several potential third parties. We may use a
portion of the net proceeds from the sale of common stock by us and/or Verio,
LLC to fund potential investments and acquisitions. Pending application of the
proceeds as described above, the net proceeds from the issuance of the common
stock in exchange for funds held in the deposit account on behalf of the holders
of the convertible preferred stock or any sale of common stock by us and/or
Verio, LLC will be invested in short-term, investment-grade securities.

     The following table sets forth certain information, received through
February 10, 2000, with respect to the number of shares of convertible preferred
stock beneficially owned and to be registered, the number of shares of common
stock beneficially owned and/or to be owned upon conversion of the convertible
preferred stock, the percentage of common stock beneficially owned and/or to be
owned after conversion of the convertible preferred stock prior to this
offering, and the number of shares of common stock to be registered, by the
selling stockholders named below. The information is based on information
provided by or on behalf of the selling stockholders and, with regard to the
beneficial holdings of the selling stockholders, is accurate only to the extent
beneficial holdings information was disclosed to us by or on behalf of the
selling stockholders. The selling stockholders and holders listed in any
supplement to this prospectus, and any transferors, pledgees, donees or
successors to these persons, may from time to time offer and sell, pursuant to
this prospectus and any subsequent prospectus supplement, any and all of these
shares. Any supplement to this prospectus may contain certain additional or
varied information about the selling stockholders and/or additional holders, and
any of their transferors, pledgees, donees or successors, and the aggregate
principal amount of the shares beneficially owned by each person that they are
offering. This information will be obtained from the selling stockholders.

     The selling stockholders may offer all, some or none of the convertible
preferred stock or common stock listed below. Because the selling stockholders
may offer all, some or none of the convertible preferred stock or common stock,
no estimate can be given as to the amount or percentage of the convertible
preferred stock or common stock that will be held by the selling stockholders
upon termination of any of the sales. In addition, the selling stockholders
identified below may have sold, transferred or otherwise disposed of all or a
portion of their convertible preferred stock or common stock since the date

stock or common stock to us in transactions exempt from the registration
requirements of the Securities Act of 1933, as amended.

supplements, form a part with respect to the resale of the shares of convertible
preferred stock from time to time in the PORTAL Market and the resale of the

 (1) The name of selling stockholders and the number of securities held by
     selling stockholders may be amended subsequent hereto pursuant to Rule
     424(b)(3) of the Securities Act of 1933, as amended.

 (2) Assumes that, for each selling stockholder, the aggregate number of shares
     of convertible preferred stock held by that selling stockholder is
     converted to common stock pursuant to a ratio of one convertible preferred
     stock equal to 1.03559763303 shares of common stock. This latter figure has
     been calculated by dividing the liquidation preference of $50.00 per share
     by the conversion price of $48.2813. The conversion price of $48.2813
     represents the conversion price after taking into account and adjusting for
     our two-for-one stock split completed on August 20, 1999. Based upon the
     aggregate conversion, a cash payment will be made in lieu of any fractional
     interest.

 (3) Unless otherwise indicated in the table or by footnote, all shares of
     common stock beneficially owned by the selling stockholders are shares
     issuable upon conversion of the convertible preferred stock. Percentage
     ownership is based on 85,530,113 shares of our common stock, representing
     78,073,811 total shares of our common stock outstanding as of January 19,
     2000 plus 7,456,302 shares of our common stock to be issued if all of our
     convertible preferred stock converts to common stock pursuant to the
     conversion ratio in footnote 2 above. The percentage ownership does not
     include shares of common stock that may be issued by us as dividends on the
     convertible preferred stock or in exchange for funds in the deposit
     account.

     We agreed with the selling stockholders to file the registration statement
to register the resale of the shares. We agreed to prepare and file all
necessary amendments and supplements to the registration statement to keep it
effective until such time as all of the securities covered by this registration
statement may be freely sold by the selling stockholders without registration
pursuant to Rule 144(k) of the Securities Act of 1933, as amended, assuming none
of the selling stockholders is an affiliate of Verio. However, with regard to BI
Partners LLC and Donald Gene Smith, on the one hand, and Merrill Lynch, Pierce,
Fenner & Smith Incorporated and NMS Services (Cayman) Inc., on the other hand,
we have agreed only to keep the registration statement effective as to our
common stock for at least 180 days in the case of the former and 120 days in the
case of the latter. For Merrill Lynch, Pierce, Fenner & Smith Incorporated, this
latter limitation only applies to the extent that the common stock it holds was
not received as a result of converting our convertible preferred stock to common
stock.

            DESCRIPTION OF THE SERIES A CONVERTIBLE PREFERRED STOCK

     On July 20, 1999, we issued and sold 7,200,000 shares of our 6.75% Series A
convertible preferred stock, par value $0.001 per share. We issued the
convertible preferred stock, in part, in order to raise funds to continue the
development and implementation of our national backbone, customer care center,
network operations center and billing and accounting services. We also raised
the funds to support our general working capital purposes and to further our
acquisition and investment strategy.

     The following summary description of our convertible preferred stock and
the deposit account is qualified in its entirety by reference to our certificate
of incorporation, the certificate of designation governing the convertible
preferred stock and the deposit agreement. Our certificate of incorporation, the
certificate of designation and the deposit agreement have been filed, or are
incorporated by reference, as exhibits to the registration statement on Form S-3
filed with the Securities and Exchange Commission. This prospectus is a part of
that registration statement. Copies of the forms of the certificate of
designation and deposit agreement will be made available to prospective
investors upon request.

RANKING

     The convertible preferred stock ranks:

     - senior to all classes of our common stock and to all classes of capital
       stock or series of preferred stock that do not expressly provide that
       they rank senior to or on a parity with the convertible preferred stock
       as to dividend distributions and distributions upon liquidation, winding
       up and dissolution;

     - on a parity with any preferred stock issued by Verio in the future and
       any classes of capital stock or series of preferred stock that expressly
       provide that they rank on a parity with the convertible preferred stock
       as to dividend distributions and distributions upon liquidation, winding
       up and dissolution; and

     - junior to all classes of capital stock and series of preferred stock that
       expressly provide that they rank senior to the convertible preferred
       stock as to dividend distributions and distributions upon liquidation,
       winding up and dissolution.

     The convertible preferred stock also ranks junior in right of payment to
all indebtedness and other liabilities of Verio.

DEPOSIT ACCOUNT

     When we sold the shares of convertible preferred stock on July 20, 1999,
purchasers of the shares deposited at the same time $24,275,155.89 of the total
purchase price of $348,300,000 into an account, which we call the deposit
account. The deposit account was established to provide for the payment of the
equivalent of the first year of dividends on the convertible preferred stock and
because various covenants and conditions contained in our debt instruments
otherwise limit our ability to pay directly cash dividends on our securities.
Norwest Bank Minnesota, N.A. holds the deposit account on behalf of the holders
of the convertible preferred stock and acts as the deposit agent for the
convertible preferred stock. The funds in the deposit account have been invested
in U.S. government obligations or U.S. government guaranteed obligations which,
together with the earnings on those funds, will be sufficient to pay in
quarterly installments the equivalent of the first year of dividends on the
convertible preferred stock.

     Through August 1, 2000, holders of the convertible preferred stock are
entitled to a quarterly cash payment from the deposit account in an amount equal
to $0.8438 per share, subject to our rights to cause shares of our common stock
to be purchased in lieu of cash. The quarterly cash payment from the deposit
account is called the quarterly return amount. Payments of the quarterly return
amount commenced November 1, 1999, and another payment occurred on February 1,
2000. Payments will continue through August 1, 2000, unless earlier terminated.
After that date, dividends will begin to accrue on the convertible

                                       29
<PAGE>   35

preferred stock. However, as we discuss below, dividends may begin to accrue
earlier if the deposit account is earlier terminated.

     Prior to each of May 1 and August 1, 2000, we may elect to issue shares of
our common stock in lieu of releasing cash from the deposit account to satisfy
the quarterly return amount. If we choose to issue common stock, Norwest Bank
will purchase from us, for transfer to each holder of our convertible preferred
stock, that number of whole shares of our common stock determined by dividing
the quarterly return amount by either,

          (A) 97% of the market value (calculated as described below) of our
     common stock, if (1) the shares of common stock are issued pursuant to a
     registration statement, (2) a shelf registration statement registering the
     resale of the shares is effective, or (3) the shares are eligible for
     immediate resale pursuant to Rule 144(k) under the Securities Act; or

          (B) in all other cases, 93% of the market value of our common stock,

in each case as of the date of the notice. In that instance, holders of
convertible preferred stock will receive shares of our common stock rather than
a cash payment. Clause (A) or (B), as the case may be, is referred to as the
"Market Value Amount."

     Market value is calculated, as of any particular date, based on the average
daily closing price over the five consecutive trading days ending immediately
prior to the particular date. The closing price for each day will be the last
sales price or, if no reported sales take place on that day, the average of the
last reported bid and asked price on that day. The closing price will be
determined from shares of our common stock admitted to trading or listed on the
principal national securities exchange for our common stock, or if not listed or
admitted to trading on the exchange, the representative closing bid price as
reported by the Nasdaq National Market or other similar organization if the
Nasdaq National Market is no longer reporting the information, or if not
available, the fair market price as determined in good faith by our board of
directors.

     Unless we have delivered to Norwest Bank a notice instructing Norwest Bank
to purchase shares of common stock from us, Norwest Bank will deliver to each
holder of convertible preferred stock the quarterly return amount on May 1 and
August 1, 2000, each such date being called a deposit payment date and the last
date also being called the deposit expiration date, unless the deposit account
is terminated earlier in the manner described below. If we choose to deliver to
Norwest Bank a notice, the notice must be given at any time prior to or on the
tenth business day prior to the applicable deposit payment date or deposit
expiration date, as the case may be. The following table sets forth each deposit
payment date/deposit expiration date and the corresponding last day that we may
give a notice relating to it:

<TABLE>

August 1, 2000.....................................   July 18, 2000
</TABLE>

     If we have delivered a notice to Norwest Bank, Norwest Bank will, as
instructed by us in the notice, purchase from us, for delivery to each holder of
convertible preferred stock in lieu of all or a portion of the quarterly return
amount which has not been previously paid in cash or shares of our common stock,
on the next deposit payment date, that number of whole shares of common stock
determined by dividing such quarterly return amount by the Market Value Amount
as of the notice date. Norwest Bank's obligation to purchase shares of common
stock from us is secured by the funds in the deposit account.

     For example, if we gave a notice to Norwest Bank on April 14, 2000 invoking
our right to have shares of common stock purchased from us in lieu of the
quarterly return amount to be paid on May 1, 2000, Norwest Bank would purchase
from us that number of whole shares of our common stock equal to the

                                       30
<PAGE>   36

quarterly return amount each holder of convertible preferred stock is to receive
divided by the Market Value Amount on April 14, 2000. Assuming that the resale
registration statement, of which this prospectus is a part, is effective at the
time that we give notice, the Market Value Amount on April 14, 2000 would be 97%
of the market value of our common stock. In this example, the market value would
be calculated as of April 14, 2000, based on the average of the daily closing
price for the five consecutive trading days ending on April 13, 2000. Assuming
the closing price for each day is the last sales price of our common stock on
the Nasdaq National Market, and assuming that the last sales price of our common
stock on each of the five consecutive trading days is $50.00 per share, the
Market Value Amount would be 97% of $50.00, or $48.50. Consequently, assuming
that there is only one holder of convertible preferred stock, the quarterly
return amount for that holder would be $0.8438 multiplied by 7,200,000 shares of
convertible preferred stock, or $6,075,360, and the number of whole shares to be
purchased would be $6,075,360 divided by $48.50, or an aggregate 125,265 shares
of our common stock.

     To the extent that we choose to have shares of common stock delivered in
lieu of cash from the deposit account, we must deliver, for and on behalf of the
deposit agent, the shares of common stock acquired by the deposit agent directly
to holders of our convertible preferred stock.

     In the event of any conversion of the convertible preferred stock into
shares of our common stock prior to the deposit expiration date, we will be paid
any funds remaining in the deposit account allocable to those shares of
convertible preferred stock so converted. As a result, holders of convertible
preferred stock will not receive any partial payment from the deposit account if
they convert their shares prior to the record date for such full quarterly
return amount.

     On the deposit expiration date, Norwest Bank is obligated to deliver to the
holders of convertible preferred stock any cash remaining in the deposit account
on that date, after first paying itself for any fees and expenses it is owed as
a result of acting as the deposit agent, unless, prior to the deposit expiration
date, we deliver a notice to Norwest Bank requiring it to purchase from us for
delivery to holders who are entitled to the proceeds from the deposit account
that number of whole shares of our common stock determined by dividing the
balance remaining in the deposit account by the Market Value Amount as of the
date of the notice.

     We retain the right to terminate the deposit account before the deposit
expiration date if:

          (A) we obtain amendments to the covenants under our various debt
     obligations permitting us to pay cash dividends; and

          (B) the trading price, on any date, for the convertible preferred
     stock equals or exceeds $50.00 per share.

     We will give notice to the holders of the convertible preferred stock, and
instruct Norwest Bank in writing immediately to distribute the remaining balance
of the deposit account to us. If we elect early termination of the deposit
account, the convertible preferred stock will begin to accrue dividends from the
last deposit payment date preceding the election to terminate the deposit
account.

     Upon the final resolution, including the final resolution of all appeals or
rights to appeal in any court, of any voluntary or involuntary dissolution,
liquidation or winding up of our company, Norwest Bank will be required to
return to the holders of the convertible preferred stock any funds at the time
remaining in the deposit account, after first paying itself for any fees and
expenses it is owed as a result of acting as the deposit agent. While we
consider the funds placed in the deposit account to be the property of the
purchasers of the convertible preferred stock and not our property, in a
bankruptcy proceeding, our creditors or a trustee in bankruptcy could claim that
those funds constituted property of our bankrupt estate. If that claim were
upheld, access to the funds in the deposit account by the purchasers of the
convertible preferred stock would be denied until all our indebtedness had been
paid in full.

     References throughout this prospectus to common stock issuable as dividends
shall be deemed to include common stock purchased from us by the deposit agent
pursuant to the deposit agreement.

DIVIDENDS

     The holders of shares of the convertible preferred stock are entitled to
receive cumulative dividends on and after August 1, 2000, or earlier if the
deposit account is terminated, and when, as and if our board of directors
declares a dividend. Any cumulative dividends are subject to the prior rights of
holders of any preferred stock ranking senior to, or on a parity with, the
convertible preferred stock.

     The cumulative dividends are payable at a rate per annum of 6.75% of the
liquidation preference of $50.00 per share, or $3.375 per share. To the extent
declared and paid, the cumulative dividends shall be distributed quarterly on
each November 1, February 1, May 1 and August 1 -- each, a dividend payment
date. If any of these dates is not a business day, the payment shall be made on
the next succeeding business day. Dividends will be paid to holders of record as
they appear on our stock register on a particular date, not more than 60 days
nor less than 10 days preceding the dividend payment date, as fixed by our board
of directors -- each, a record date. Dividends will be payable at our option:

     - in cash;

     - by delivery of fully paid and non-assessable shares of our common stock
       to holders (determined as described below); or

     - any combination of the foregoing.

     Although we have the option of paying dividends in cash, we are restricted
from doing so by the various covenants and conditions contained in our debt
instruments. Because of these restrictions, it is unlikely that we will pay
dividends in cash.

     If we pay dividends in shares of common stock, the number of shares of
common stock to be issued on each dividend payment date will be determined by
dividing the total dividend to be paid on each share of convertible preferred
stock by the Market Value Amount as of the applicable record date.

     For example, if a record date is established by our board of directors for
October 18, 2000 relating to the dividend to be paid on November 1, 2000, and if
we elect to pay the dividend in shares of common stock, the number of shares of
common stock to be issued on November 1, 2000 to each holder of convertible
preferred stock would be that number of whole shares of our common stock equal
to the quarterly dividend payment amount each holder of convertible preferred
stock is to receive divided by the Market Value Amount on October 18, 2000.
Assuming that the resale registration statement, of which this prospectus is a
part, is effective at the time that we give notice, the Market Value Amount on
October 18, 2000 would be 97% of the market value of our common stock. In this
example, the market value would be calculated as of October 18, 2000, based on
the average of the daily closing price for the five consecutive trading days
ending on October 17, 2000. Assuming the closing price for each day is the last
sales price of our common stock on the Nasdaq National Market, and assuming that
the last sales price of our common stock on each of the five consecutive trading
days is $60.00 per share, the Market Value Amount would be 97% of $60.00, or
$58.20. Consequently, assuming that there are two holders holding collectively
all 7,200,000 shares of convertible preferred stock, the quarterly dividend
payment for each holder would be $0.8438 multiplied by 3,600,000 shares of
convertible preferred stock, or $3,037,680, and the number of whole shares to be
purchased would be $3,037,680 divided by $58.20, or an aggregate 52,193 shares
of our common stock.

     We will not issue fractional shares of common stock as dividends. Instead,
proceeds from the sale of aggregated fractional interests will be distributed to
the holders of the convertible preferred stock in cash. We will pay the expenses
of the transfer agent with respect to the sale of the aggregated fractional
interests, including brokerage commissions. In the event the sale by the
transfer agent of the aggregated fractional interests would be restricted, Verio
and the transfer agent will agree upon other appropriate arrangements for
obtaining cash in lieu of the fractional interests. Dividends payable on the
convertible preferred stock for any period greater or less than a full quarterly
dividend period will be computed on the basis of a 360-day year consisting of
twelve 30-day months.

                                       32
<PAGE>   38

     Dividends on the convertible preferred stock will accrue:

     - whether or not we have earnings or profits;

     - whether or not there are funds legally available for the payment of such
       dividends; and

     - whether or not dividends are declared.

     Dividends will accumulate interest free to the extent they are not paid on
the dividend payment date for the period to which they relate.

     We will only declare dividends if all dividends for preceding periods have
been declared and paid.

     We will not declare and pay any dividends on or redeem or purchase any of
our stock ranking junior to or ratably with the convertible preferred stock,
unless full cumulative dividends on the convertible preferred stock have been
paid or declared and a sum sufficient for the payment of dividends is set apart.
However, regardless of whether we have paid full cumulative dividends on the
convertible preferred stock, we may do the following:

          (1) declare and pay a dividend on junior stock payable solely in
     shares of the junior stock or options, warrants or rights to purchase the
     junior stock;

          (2) declare and pay a dividend on stock ranking ratably with the
     convertible preferred stock payable solely in shares of our stock ranking
     junior to or ratably with the convertible preferred stock or options,
     warrants or rights to purchase our stock ranking junior to or ratably with
     the convertible preferred stock;

          (3) declare and pay any dividend on, or redeem or purchase, stock
     ranking junior to or ratably with the convertible preferred stock so long
     as the money for the dividend, redemption or purchase is derived from the
     proceeds of the offering of the same securities or a substantially
     concurrent offering of related securities; and

          (4) we may make cash payments in lieu of fractional shares pursuant to
     any stock split or warrant, option or other similar agreement.

     If full dividends have not been declared and paid or set apart on the
convertible preferred stock and any other preferred stock ranking ratably with
the convertible preferred stock as to dividends, dividends may be declared and
paid on the convertible preferred stock and the other ratable preferred stock.
In this case, the dividends shall be declared and paid pro rata so that the
amounts of dividends declared per share on the convertible preferred stock and
the other ratable preferred stock will in all cases bear the same ratio to each
other that accrued and unpaid dividends per share on the shares of the
convertible preferred stock and the other preferred stock bear to each other.
Moreover, if the dividends are paid in cash on the other ratable preferred
stock, dividends will also be paid in cash on the convertible preferred stock.

     The holders of convertible preferred stock at the close of business on a
record date will be entitled to receive the dividend payment on those shares on
the corresponding dividend payment date. This right applies even if the holder
subsequently converts the convertible preferred stock to our common stock. This
right also applies even if we default in our payment of the dividend due on that
dividend payment date. Except for shares of convertible preferred stock
converted after a dividend record date, we will make no payment or allowance for
unpaid dividends on shares of our convertible preferred stock converted into our
common stock or for dividends on the shares of our common stock issued upon
conversion of our convertible preferred stock.

CONVERSION RIGHTS

     Each share of convertible preferred stock is convertible at any time at the
option of the holder into that number of shares of our common stock equal to the
liquidation preference of $50.00 divided by a conversion price of $48.2813.
However, the conversion price may be adjusted as described below. We refer to
the conversion price as adjusted as the conversion price in this prospectus.
                                       33
<PAGE>   39

     For example, under the conversion price in effect as of the date of this
prospectus, if all 7,200,000 shares of convertible preferred stock were held by
one holder and were converted to common stock, the convertible preferred stock
would convert into 7,456,302 shares of our common stock. If this same conversion
of the convertible preferred stock had occurred on December 17, 1999, when there
were 77,740,607 shares of our common stock outstanding, the conversion would
have resulted in an aggregate 85,196,909 shares of common stock outstanding. The
common stock issued upon the conversion of the convertible preferred stock on
December 17, 1999 would have represented approximately 8.75% of total amount of
common stock outstanding.

     We have the option of paying all accumulated and unpaid dividends in cash
or by issuing shares of our common stock equal to the amount of accumulated and
unpaid dividends divided by the Market Value Amount as of the conversion date.

     Convertible preferred stock surrendered for conversion during the period
between the close of business on any record date and the opening of business on
the corresponding dividend payment date must be accompanied by payment of an
amount equal to the dividend payable on the shares on the dividend payment date.
This does not apply if the convertible preferred stock is converted after the
issuance of a notice of redemption and the redemption date occurs during the
same period or coincides with the dividend payment date. In this case, the
holder will continue to be entitled to the dividend.

     A holder of convertible preferred stock on a record date who, or whose
transferee, tenders any of the shares for conversion into shares of common stock
on the dividend payment date will receive the dividend payable by Verio on the
shares of convertible preferred stock on the dividend payment date. The
converting holder need not include payment of the amount of the dividend upon
surrender of convertible preferred stock for conversion.

     Except as provided above, we will make no payment or allowance for unpaid
dividends on converted shares or for dividends on the common stock issued upon
conversion of the convertible preferred stock.

     If we call our convertible preferred stock for redemption, the conversion
right will terminate at the close of business on the date immediately prior to
the date fixed for redemption. The conversion right will be lost if not
exercised prior to that time, unless we default in payment of our redemption
obligation.

     We will not issue any fractional shares of common stock upon conversion of
the convertible preferred stock. Instead we will pay a cash adjustment in
respect of any fractional interest based on the then current market price of the
common stock.

     The conversion price on our convertible preferred stock is subject to
adjustment upon the occurrence of any of the following dilutive events:

     - any redemption or dividend or other distribution payable in shares of our
       common stock to all holders of any class of capital stock of our company;
       however, this bullet point does not apply if we issue shares of our
       common stock in connection with (1) any redemption of, dividend on or
       conversion of the convertible preferred stock or (2) any payment to all
       holders of the convertible preferred stock based upon the number of
       shares of our common stock into which the convertible preferred stock is
       then convertible;

     - any issuance to all holders of our common stock of rights, options or
       warrants entitling them to subscribe for or purchase shares of our common
       stock or securities convertible into or exchangeable for shares of our
       common stock at less than market value as of the date of issuance; if the
       rights, options or warrants are only exercisable upon the occurrence of
       certain triggering events, then the conversion price will not be adjusted
       until the triggering events occur; however, no adjustment will be made if
       the holder of shares of the convertible preferred stock would be entitled
       to receive the rights, options or warrants upon conversion at any time of
       the convertible preferred stock into our common stock;

     - any subdivision, combination or reclassification of our common stock;

                                       34
<PAGE>   40

     - any distribution consisting exclusively of cash, other than a transaction
       for which the last paragraph in this section "-- Conversion Rights" below
       is applicable, to all holders of shares of our common stock in an
       aggregate amount that, combined together with (1) all other such cash
       distributions made within the then preceding 12 months in respect of
       which no adjustment has been made and (2) any cash and the fair market
       value of other consideration paid or payable in respect of any tender
       offer by us or any of our subsidiaries for shares of our common stock
       concluded within the then preceding 12 months in respect of which no
       adjustment has been made, exceeds 15% of our market capitalization
       immediately prior to the distribution; market capitalization is defined
       as the product of the then current market price of our common stock times
       the number of shares of our common stock then outstanding on the record
       date of the distribution;

     - the completion of a tender or exchange offer which is made for shares of
       our common stock and involves an aggregate consideration that, together
       with (1) any cash and other consideration payable in a tender or exchange
       offer for shares of any of our common stock expiring within the then
       preceding 12 months in respect of which no adjustment has been made and
       (2) the aggregate amount of any cash distributions referred to in the
       fourth bullet point of this paragraph to all holders of our common stock
       within the then preceding 12 months in respect of which no adjustments
       have been made, exceeds 15% of our market capitalization immediately
       prior to the expiration of the tender offer; or

     - a distribution to all holders of our common stock consisting of evidences
       of indebtedness, shares of capital stock other than our common stock or
       assets, including securities; this bullet point does not apply to those
       dividends and those issuances of rights, options, warrants and other
       distributions for which an adjustment to the conversion price as referred
       to above is applicable; this bullet point also does not apply to a
       distribution in connection with a merger effected solely to reflect a
       change in the jurisdiction of incorporation of our company.

     No adjustment of the conversion price will be required to be made:

     - until cumulative adjustments amount to one percent of the conversion
       price; and

     - with respect to rights or warrants issued pursuant to certain employee
       benefit plans.

     Upon each event causing an adjustment of the conversion price, we shall
calculate the adjusted conversion price pursuant to a particular, detailed
formula. For example, when we carried out our two-for-one stock split that was
completed on August 20, 1999, a conversion price adjustment was made. In that
case, the adjustment was calculated using the following formula: the product of
(A) the quotient of the number of shares of common stock outstanding immediately
prior to the stock split, divided by the number of shares of common stock
outstanding immediately after the completion of the stock split, such quotient
in this case being 0.5, multiplied by (B) the conversion price existing
immediately prior to the stock split, in this case $96.5625. As a result, the
adjusted conversion price reflected by the product of (A) and (B) is $48.2813.

     We also may choose to decrease the conversion price by any amount for any
period of at least 20 days, so long as the decrease is irrevocable during that
period. Any time that we determine to make a decrease we shall give at least 15
days' notice before carrying it out.

     In addition to the adjustments described above, we are permitted to make
reductions in the conversion price as we determine to be advisable in order that
any stock dividend, subdivision of shares, distribution of rights to purchase
stock or securities or distribution of securities convertible into or
exchangeable for stock made by Verio to our stockholders will not be taxable to
the recipients. In the event we elect to make this type of reduction in the
conversion price, we will comply with the requirements of Rule 14e-1 under the
Securities Exchange Act of 1934, and any other securities laws and regulations
under the Securities Exchange Act, if and to the extent that these laws and
regulations are applicable in connection with the reduction of the conversion
price. See "Federal Tax Considerations."

                                       35
<PAGE>   41

     As provided above, anti-dilution adjustments occur if we distribute to all
holders of our common stock rights or warrants entitling them to subscribe for
or purchase shares of our common stock or securities convertible into or
exchangeable for shares of our common stock at less than market value as of the
date of issuance. In the event that we distribute to all holders of our common
stock rights or warrants other than these less-than-market rights and warrants,
and so long as the rights or warrants that we do distribute have not expired or
been redeemed by us, each holder of convertible preferred stock will be entitled
to receive upon conversion of the convertible preferred stock, in addition to
the common stock then issuable upon conversion, which we call the conversion
shares, a number of rights or warrants to be determined as follows:

     - if the conversion occurs on or prior to the date for the distribution to
       the holders of rights or warrants of separate certificates evidencing the
       rights or warrants, called the distribution date, the same number of
       rights or warrants to which a holder of a number of shares of our common
       stock equal to the number of conversion shares is entitled at the time of
       the conversion in accordance with the terms and provisions applicable to
       the rights or warrants, and

     - if the conversion occurs after the distribution date, the same number of
       rights or warrants to which a holder of the number of shares of our
       common stock into which the convertible preferred stock was convertible
       immediately prior to the distribution date would have been entitled on
       the distribution date in accordance with the terms and provisions of and
       applicable to the rights or warrants.

     Except as stated above, the conversion price will not be adjusted for the
issuance of common stock, or any securities convertible into or exchangeable for
common stock or carrying the right to purchase any of the foregoing, in exchange
for cash, property or services.

     There will be no adjustment of the conversion price in any of the following
three cases:

          (1) any merger or consolidation of our company, other than a merger or
     consolidation in which we are the continuing corporation and in which the
     common stock outstanding immediately prior to the merger or consolidation
     is not exchanged for cash, securities or other property of another
     corporation;

          (2) any sale or transfer to another corporation of the property of
     Verio as an entirety or substantially as an entirety; or

          (3) any statutory exchange of securities with another corporation,
     other than in connection with a merger or acquisition.

Instead, each share of the then outstanding convertible preferred stock will
become convertible only into the kind and amount of securities, cash or other
property receivable upon the merger, consolidation, sale, transfer or statutory
exchange by a holder of the number of shares of common stock into which the
convertible preferred stock was convertible immediately prior to the merger,
consolidation, sale, transfer or statutory exchange, assuming the holder of
common stock failed to exercise his rights of election, if any, as to the kind
or amount of securities, cash or other property receivable upon the merger,
consolidation, sale, transfer or statutory exchange. In the case of a merger of
our company with or into another company or any other transaction of the type
mentioned above that results in the payment of cash to the holders of our common
stock, the effect of these provisions would be that, after their application,
each share of convertible preferred stock would be convertible at the conversion
price in effect at the time into the same amount of cash per share into which
each share of convertible preferred stock would have been convertible had the
share been converted into common stock immediately prior to the effective date
of the cash merger or transaction. Depending upon the terms of the cash merger
or transaction, the aggregate amount of cash into which the shares of
convertible preferred stock would be converted could be more or less than the
liquidation preference of $50.00 per share with respect to the convertible
preferred stock.

                                       36
<PAGE>   42

CHANGE OF CONTROL

     Upon any cash change of control of Verio, as defined in the next paragraph,
holders of convertible preferred stock will, if the market value of our common
stock at the time of the cash change of control is less than the conversion
price, have a one time option, upon not less than 30 days' notice nor more than
60 days' notice, to convert all of their outstanding shares of convertible
preferred stock into shares of our common stock at an adjusted conversion price
equal to the greater of (1) the market value of our common stock as of the date
of the cash change of control and (2) $49.0208. In lieu of issuing the shares of
our common stock issuable upon conversion of the convertible preferred stock in
the event of a cash change of control, we may, at our option, make a cash
payment equal to the market value of the common stock otherwise issuable.

     Our certificate of designation for the convertible preferred stock defines
a cash change of control as any of the following events:

     - our company consolidates or merges with or into any person or conveys,
       transfers or leases all or substantially all of our assets to any person,
       or any corporation consolidates or merges into or with our company, in
       any of these events pursuant to a transaction in which our outstanding
       voting stock is changed into or exchanged for consideration in which 50%
       or less of the value received by holders of the stock consists of common
       stock that has been admitted for listing on a national securities
       exchange or quoted on the Nasdaq National Market; or

     - our company is liquidated or dissolved or adopts a plan of liquidation or
       dissolution.

     The phrase "all or substantially all" of the assets of our company is
likely to be interpreted by reference to applicable state law at the relevant
time, and will be dependent on the facts and circumstances existing at that
time. As a result, there may be a degree of uncertainty in ascertaining whether
a sale or transfer is of "all or substantially all" of our assets.

LIQUIDATION RIGHTS

     Upon any liquidation, dissolution or winding up of Verio, the holders of
convertible preferred stock are entitled to receive a liquidation preference of
$50.00 per share, plus an amount equal to any accrued and unpaid dividends to
the date of payment. These amounts shall be paid before any distribution of
assets is made to holders of common stock or any other stock that ranks junior
to the convertible preferred stock as to liquidation rights. The rights granted
to holders of shares of convertible preferred stock are subject to the rights of
creditors of Verio and holders of any preferred stock senior or on a parity in
right of payment to the rights possessed by the holders of convertible preferred
stock in the event of a liquidation, dissolution or winding up of Verio.

     The holders of convertible preferred stock and all series or classes of
Verio's stock issued after the date of the issuance of the convertible preferred
stock that rank on a parity as to liquidation rights with the convertible
preferred stock are entitled to share ratably, in accordance with the respective
preferential amounts payable on the stock, in any distribution which is not
sufficient to pay in full the aggregate of all amounts to which the holders are
entitled.

     After payment in full of the liquidation preference on the convertible
preferred stock, the holders of the convertible preferred stock will not be
entitled to participate in any distribution of our remaining assets.

     A merger, consolidation, or other business combination of our company with
or into another company or other entity, a statutory exchange of securities with
another company and a sale or transfer of all or part of our assets for cash,
securities or other property will not be considered a liquidation, dissolution
or winding up of Verio unless the merger, consolidation, combination, exchange,
sale or transfer shall be in connection with a liquidation, dissolution or
winding up of Verio.

REDEMPTION

  Provisional Redemption

     The convertible preferred stock is not subject to any sinking fund or other
similar provisions. We may redeem the convertible preferred stock at a
redemption price of 102.0000% of the liquidation preference, plus accumulated
and unpaid dividends, if any, to the redemption date -- which we refer to in
this prospectus as the provisional redemption date -- on or after August 1,
2001, but prior to August 1, 2002 -- which we refer to in this prospectus as the
provisional redemption -- if the trading price of our common stock equals or
exceeds $144.8438 per share for 20 trading days within any 30 trading day
period.

     If we undertake a provisional redemption, holders of convertible preferred
stock that we call for redemption will also receive a payment -- which we call
the additional payment -- in an amount equal to the present value of the total
value of the dividends that would have been payable on the convertible preferred
stock after the provisional redemption date for the period from the provisional
redemption date to August 1, 2002 -- which we call the additional period. The
present value will be calculated using the bond equivalent yield on U.S.
Treasury notes or bills having a term nearest in length to that of the
additional period.

  Optional Redemption

     Except in the foregoing circumstances, we may not redeem the convertible
preferred stock prior to August 1, 2002. Beginning on August 1, 2002, we may
redeem the convertible preferred stock during the twelve-month periods
commencing on August 1 of the years indicated below -- which we refer to in this
prospectus as the optional redemption -- at the following redemption prices,
expressed as a percentage of the liquidation preference of $50.00 per share,
plus in each case all accumulated and unpaid dividends to the date of
redemption.

  Redemption Procedures

     We may effect any provisional or optional redemption, in whole or in part,
by delivering notice of the redemption to the holders of the convertible
preferred stock not less than 20 nor more than 60 days prior to the scheduled
redemption date. The redemption price, including any additional payment, due to
any holder of convertible preferred stock may be paid at our option, subject to
applicable law:

     - in cash;

     - through delivery of fully paid and non-assessable shares of our common
       stock; or

     - a combination of both.

     In the event that fewer than all the outstanding shares of convertible
preferred stock are to be redeemed, the shares to be redeemed will be determined
pro rata or by lot. If we elect to make redemption payments in shares of our
common stock, the number of shares of our common stock that we distribute will
be calculated by dividing the redemption payment, including any additional
payment, by the Market Value Amount as of the redemption notice date. From and
after the applicable redemption date, unless we default in the payment of the
redemption price, including any additional payment, dividends on the shares of
convertible preferred stock to be redeemed on the redemption date shall cease to
accumulate. Additionally, the shares of convertible preferred stock shall no
longer be deemed to be outstanding, and all

                                       38
<PAGE>   44

rights of the holders of the convertible preferred stock as stockholders will
cease, except for the right to receive the redemption price, including any
additional payment. If any dividends on the convertible preferred stock are in
arrears, no shares of convertible preferred stock will be redeemed unless all
outstanding shares of convertible preferred stock are simultaneously redeemed.

     Our ability to redeem any of the convertible preferred stock is, and may
continue to be, limited by the terms of our other financing arrangements and
applicable law. In fact, we would currently be prohibited by the terms of our
credit facility and our outstanding senior notes from redeeming the convertible
preferred stock.

VOTING RIGHTS

     The holders of the convertible preferred stock will have no voting rights
except as described below or as required by law. In exercising any vote as
allowed below or as required by law, each outstanding share of convertible
preferred stock will be entitled to one vote. However, shares of convertible
preferred stock held by Verio or any entity controlled by Verio will have no
voting rights.

     If the dividends on the convertible preferred stock are in arrears for six
quarters, whether or not consecutive, the number of directors of Verio will be
increased by two, and the holders of the convertible preferred stock -- voting
separately as a class with holders of any outstanding shares of stock on a
parity as to dividends with the convertible preferred stock on which like voting
rights have been conferred and are exercisable -- will be entitled to elect the
two additional directors to the board of directors at any meeting of
stockholders of Verio at which directors are to be elected. A special meeting
will be scheduled at the direction of 25% of the holders of convertible
preferred stock for this purpose. These voting rights will continue until the
time that the dividend arrearage on the convertible preferred stock has been
paid in full or sums set aside for payment of the dividend arrearage.

     In addition, so long as any convertible preferred stock is outstanding, we
will not, without the affirmative vote or consent of the holders of at least a
majority of all outstanding shares of convertible preferred stock, amend, alter
or repeal any provision of our certificate of incorporation or bylaws so as to
affect materially and adversely the relative rights, preferences,
qualifications, limitations or restrictions of the convertible preferred stock.
The certificate of designation also provides that, except as set forth above,
(1) the creation, authorization or issuance of any shares or series of preferred
stock, or (2) the increase or decrease in the amount of authorized capital stock
of any class, including any preferred stock, shall not require the consent of
the holders of convertible preferred stock and shall not be deemed to affect
adversely the rights, preferences, privileges or voting rights of the
convertible preferred stock.

     The foregoing voting provisions will not apply if, at or prior to the time
when the act with respect to which a vote would otherwise be required shall be
effected, all outstanding shares of convertible preferred stock shall have been
redeemed or called for redemption upon proper notice, and we shall have reserved
sufficient shares of common stock, or set aside sufficient cash, to effect the
redemption.

REGISTRATION RIGHTS; ADDITIONAL DIVIDENDS

     Pursuant to a registration rights agreement, we have granted a number of
rights to the holders of the convertible preferred stock and common stock issued
or issuable as dividends or upon conversion of the convertible preferred stock
and common stock purchased from the deposit account -- which we refer to as the
subject securities. These rights include the following:

     - we must have filed, at our cost, by November 17, 1999, a shelf
       registration statement with the Securities and Exchange Commission with
       respect to resales of the convertible preferred stock and the common
       stock issuable upon conversion and the issuance and resale of the common
       stock issuable by us as dividends;

     - we will use our reasonable best efforts to cause the shelf registration
       statement to be declared effective under the Securities Act by February
       15, 2000; and

                                       39
<PAGE>   45

     - we will keep the shelf registration statement continuously effective and
       useable under the Securities Act, with some exceptions, until the date on
       which any subject securities received or receivable by non-affiliates of
       Verio may be freely sold by their holders without restriction pursuant to
       Rule 144(k) or any successor provision promulgated by the Securities and
       Exchange Commission under the Securities Act or otherwise.

     If the shelf registration statement:

          - had not been filed with the Securities and Exchange Commission by
     November 17, 1999, or has not been declared effective by the Securities and
     Exchange Commission by February 15, 2000; or

          - is filed and declared effective but thereafter ceases to be
     effective, without being succeeded immediately by a replacement shelf
     registration statement filed and declared effective, or useable for the
     offer and sale of Transfer Restricted Securities, as defined below, for a
     period of time exceeding any suspension period defined below,

then either event will be considered a registration default. If we incur a
registration default, then additional dividends will accrue on the convertible
preferred stock constituting "Transfer Restricted Securities", as defined below,
held by each holder who has complied with its obligations under the registration
rights agreement.

     In the first quarterly period following a registration default, an
additional dividend will accrue at a rate of 0.25% per quarterly period. The
rate of the additional dividend will increase by an additional 0.25% per
quarterly period until we cure all registration defaults. After we cure all
registration defaults, the rate at which dividends accrue on the convertible
preferred stock will return to 6.75% per annum.

     The amount of additional dividends that accrue for any quarterly period may
be paid, at our option:

     - in cash;

     - by delivery of fully paid and non-assessable shares of our common stock;
       or

     - a combination of both of the above.

     If we elect to pay the additional dividends in shares of our common stock,
the number of shares that we distribute will be calculated by dividing the
additional dividend amount by the Market Value Amount as of the record date.

     "Transfer Restricted Securities" means each share of convertible preferred
stock, each share of common stock issued or issuable as a dividend or upon
conversion of the convertible preferred stock and each share of common stock
purchased from the deposit account until the date on which such security:

          (A) has been transferred pursuant to the shelf registration statement
     or another registration statement covering the security which has been
     filed with the Securities and Exchange Commission pursuant to the
     Securities Act, in either case after the registration statement has become
     effective under the Securities Act;

          (B) has been transferred pursuant to Rule 144 under the Securities
     Act, or any similar provision then in force;

          (C) may be freely sold or transferred pursuant to Rule 144(k) under
     the Securities Act, or any similar provision then in force; or

          (D) in the opinion of counsel to Verio may be freely sold without
     restriction under the Securities Act by the holder thereof.

     A holder of convertible preferred stock or the common stock issuable as a
dividend or upon conversion of the convertible preferred stock that sells the
securities pursuant to a shelf registration statement is required to be named as
a selling security holder in the related prospectus and to deliver a
                                       40
<PAGE>   46

prospectus and any subsequent prospectus supplement to purchasers. The holder
also will be subject to various civil liability provisions under the Securities
Act in connection with the sales, and will be bound by the provisions of the
registration rights agreement that are applicable to the holder, including
indemnification and contribution rights or obligations with respect to the
information supplied by the holder.

     We have distributed a questionnaire to each beneficial holder of
convertible preferred stock as of a specified date to obtain information
regarding the selling security holders for inclusion in this prospectus. We will
pay all expenses of the shelf registration statement.

     Each holder of convertible preferred stock, or the common stock issuable as
a dividend or upon conversion of the convertible preferred stock, will be
provided with copies of this prospectus and any subsequent prospectus
supplement, which will be a part of the shelf registration statement. In
addition, we will take other actions as are required to permit unrestricted
resales of the convertible preferred stock and common stock.

     We will be permitted to suspend the use of any prospectus which is a part
of the shelf registration statement for a suspension period not to exceed 60
days in any 90-day period and not to exceed 90 days in any 12-month period under
various circumstances relating to pending corporate developments, public filings
with the Securities and Exchange Commission and similar events. If we suspend
the use of the prospectus for a period that exceeds the periods specified in the
foregoing sentence, additional dividends will begin to accrue on the convertible
preferred stock at the rates described above.

BOOK-ENTRY, DELIVERY AND FORM

     The convertible preferred stock sold was issued in the form of one or more
global securities. The global securities were deposited with, or on behalf of,
the Depository Trust Company, which we refer to as the Depositary, and
registered in the name of the Depositary or its nominee. Except as provided
below, the global securities may be transferred, in whole and not in part, only
to the Depositary or another nominee of the Depositary. Investors may hold their
beneficial interests in the global securities directly through the Depositary if
they have an account with the Depositary or indirectly through organizations
which have accounts with the Depositary.

     Shares of convertible preferred stock that are issued as described below
under the section "Certificated Convertible Preferred Stock" will be issued in
definitive form. Upon the transfer of convertible preferred stock in definitive
form, the convertible preferred stock will be exchanged for an interest in the
global securities representing the liquidation preference of convertible
preferred stock being transferred, unless the global securities have previously
been exchanged for convertible preferred stock in definitive form.

     The Depositary has advised us as follows:

     - The Depositary is a limited-purpose trust company organized under the
       laws of the State of New York and is a member of the Federal Reserve
       System;

     - The Depositary is a "clearing corporation" within the meaning of the New
       York Uniform Commercial Code and a "clearing agency" registered pursuant
       to the provisions of Section 17A of the Securities Exchange Act of 1934,
       as amended;

     - The Depositary was created to hold securities of institutions that have
       accounts with the Depositary -- which we refer to as participants -- and
       to facilitate the clearance and settlement of securities transactions
       among its participants in these securities through electronic book-entry
       changes in accounts of the participants, thereby eliminating the need for
       physical movement of securities certificates;

     - The Depositary's participants include securities brokers and dealers,
       which may include the initial purchasers of the convertible preferred
       stock, banks, trust companies, clearing corporations and other
       organizations;
                                       41
<PAGE>   47

     - Access to the Depositary'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 securities, the Depositary credited, on its
book-entry registrations and transfer system, the liquidation preference of the
convertible preferred stock of $50.00 per share represented by such global
securities to the accounts of participants. The accounts credited were
designated by the initial purchasers of the convertible preferred stock.
Ownership of beneficial interests in the global securities is limited to
participants or persons that may hold interests through participants. Ownership
of beneficial interests in the global securities are shown on, and the transfer
of those ownership interests will be effected only through, records maintained
by the Depositary, with respect to participants' interest, and the participants,
with respect to the owners of beneficial interests in the global securities
other than participants. The laws of some jurisdictions may require that some
purchasers of securities take physical delivery of the securities in definitive
form. These limits and laws may impair the ability to transfer or pledge
beneficial interests in the global securities.

     So long as the Depositary, or its nominee, is the registered holder and
owner of the global securities, the Depositary or the nominee, as the case may
be, will be considered for all purposes the sole legal owner and holder of the
related convertible preferred stock. Except as provided below, owners of
beneficial interest in the global securities:

     - will not be entitled to have the convertible preferred stock, represented
       by the global securities, registered in their names;

     - will not receive or be entitled to receive physical delivery of
       certificated convertible preferred stock in definitive form; and

     - will not be considered to be the owners or holders of any convertible
       preferred stock under the global securities.

     We understand that under existing industry practice, in the event an owner
of a beneficial interest in the global securities desires to take any action
that the Depositary, as the holder of the global securities, is entitled to
take, the Depositary will authorize the participants to take the action, and
that the participants will authorize beneficial owners owning through the
participants to take the action or would otherwise act upon the instructions of
beneficial owners owning through them.

     Payment in respect of dividends and redemption payments on convertible
preferred stock represented by the global securities registered in the name of
and held by the Depositary or its nominee will be made to the Depositary or its
nominee, as the case may be, as the registered owner and holder of the global
securities.

     Upon receipt of any dividend or redemption payment on the global
securities, the Depositary or its nominee is expected to credit participants'
accounts with payments in amount proportionate to their respective beneficial
interests in the liquidation preference of the global securities as shown on the
records of the Depositary or its nominee. Payments by participants to owners of
beneficial interest in the global securities held through the participants are
expected to be governed by standing instructions and customary practices and are
expected to be the responsibility of the participants.

     We 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 the global securities for any convertible preferred stock. We also
will not have any responsibility or liability for maintaining, supervising or
reviewing any records relating to the beneficial ownership interest. Moreover,
we will not have any responsibility or liability for any other aspect of the
relationship between the Depositary and its participants or the relationship
between the participants and the owners of beneficial interest in the global
securities owning through the participants.

                                       42
<PAGE>   48

     Unless and until they are exchanged in whole or in part for certificated
convertible preferred stock in definitive form, the global securities may not be
transferred except as a whole:

     - by the Depositary to a nominee of the Depositary;

     - by a nominee of the Depositary to the Depositary; or

     - by a nominee of the Depositary to another nominee of the Depositary.

     Although the Depositary has agreed to the foregoing procedures in order to
facilitate transfers of interests in the global securities among participants of
the Depositary, it is under no obligations to perform or continue to perform
these procedures, and these procedures may be discontinued at any time. We and
our transfer agent will not have any responsibility for the performance by the
Depositary or its participants or indirect participants of their respective
obligations under the rules and procedures governing their operations.

CERTIFICATED CONVERTIBLE PREFERRED STOCK

     The convertible preferred stock represented by the global securities is
exchangeable for certificated convertible preferred stock in definitive form of
like tenor as the convertible preferred stock if either of the following is
applicable:

     - the Depositary notifies us that it is unwilling or unable to continue as
       Depositary for the global securities and a successor is not promptly
       appointed or if at any time the Depositary ceases to be a clearing agency
       registered under the Exchange Act; or

     - we in our discretion at any time determine not to have all of the
       convertible preferred stock represented by the global securities.

     Any convertible preferred stock that is exchangeable pursuant to the
preceding paragraph is exchangeable for certificated convertible preferred stock
issuable in authorized denominations and registered in such names as the
Depositary shall direct. Except as provided above, the global securities are not
exchangeable, except for global securities of the same aggregate denominations
to be registered in the name of the Depositary or its nominee.

     In addition, certificates will bear a legend restricting transfer of the
certificates although, with respect to the convertible preferred stock, the
legend does allow for some transfers. We also may determine that the
certificates will no longer bear a legend in accordance with applicable law.

     In connection with the provisions set forth above, after transfer of any
convertible preferred stock or common stock issued as a dividend on or upon
conversion of the convertible preferred stock during the period of effectiveness
of this registration statement, the requirement that the particular convertible
preferred stock or common stock be issued in global form shall cease to apply
and the shares of convertible preferred stock or common stock, as the case may
be, will be available to the transferee in global or fully registered
certificated form.

OTHER PROVISIONS

     The shares of convertible preferred stock and the common stock issuable by
us as dividends and upon conversion of the convertible preferred stock, when
issued, were or will be duly and validly issued, fully paid and non-assessable.
The holders of shares of convertible preferred stock and the shares of common
stock have no preemptive rights with respect to any securities of Verio.

     The registrar, transfer agent, conversion agent, and dividend disbursing
agent for the convertible preferred stock and the transfer agent and registrar
for the common stock issuable as dividends and upon conversion of the
convertible preferred stock will be Norwest Shareowner Services.

                          DESCRIPTION OF CAPITAL STOCK

     The following description of our capital stock is based upon our
certificate of incorporation, our bylaws, our warrants outstanding, and the
registration rights relating to certain of our shares. The description is not
complete and is qualified in its entirety by reference to all of these
documents, each of which has been filed with the Securities and Exchange
Commission.

AUTHORIZED CAPITAL STOCK

     Our authorized capital stock consists of 137,500,000 shares, consisting of
125,000,000 shares of common stock, par value $0.001 per share, and 12,500,000
shares of preferred stock, par value $0.001 per share. As of January 19, 2000,
there were 78,073,811 shares of common stock outstanding and, as of January 18,
2000, there were 7,200,000 shares of 6.75% Series A convertible preferred stock
outstanding.

COMMON STOCK

     Holders of our common stock are entitled to one vote for each share held of
record on all matters submitted to a vote of the stockholders. Subject to
preferences that may be applicable to any then outstanding preferred stock,
holders of our common stock are entitled to receive ratably such dividends as
may be declared by the board out of funds that are legally available. In the
event of a liquidation, dissolution or winding up of Verio, holders of our
common stock are entitled to share ratably in all assets remaining after payment
of liabilities and the liquidation of preferences of any outstanding shares of
preferred stock, if any. Holders of our common stock have no preemptive rights
or rights to convert their shares into any other securities. There are no
redemption or sinking fund provisions applicable to the common stock. All
outstanding shares of common stock are fully paid and non-assessable. The rights
of holders of common stock are subject to, and may be adversely affected by, the
rights of any series of preferred stock which we have issued or may issue in the
future. The common stock is admitted for trading on the Nasdaq National Market
under the symbol "VRIO." The transfer agent for the common stock is Norwest
Shareowner Services.

PREFERRED STOCK

     The board has the authority to issue from time to time up to 12,500,000
shares of preferred stock in one or more series and to fix the powers,
designations, preferences and relative, participating, optional or other rights
thereof, including dividend rights, conversion rights, voting rights, redemption
terms, liquidation preferences -- any or all of which may be greater than the
rights of the common stock -- and the number of shares constituting each such
series, without any further vote or action by our stockholders. Except for the
6.75% Series A convertible preferred stock, there are no other shares of
preferred stock outstanding.

WARRANTS

     As of January 7, 2000, we had warrants outstanding to purchase an aggregate
of approximately 248,920 shares of common stock at an exercise price per share
of $0.01. These warrants were issued in connection with the issuance of the 1997
Notes and are currently exercisable by the holders. Holders of these warrants
also are entitled to certain registration rights. See "-- Registration Rights."

     In addition, in connection with our acquisition of Hiway, each former Hiway
warrant was assumed by Verio. Such warrant became a warrant to purchase, at the
same aggregate exercise price and on substantially the same terms and conditions
as such Hiway warrant, that number of shares of our common stock which the
holder would have been entitled to receive had such warrant been exercised prior
to the completion of the acquisition, and had the total consideration we paid
been entirely in shares of our common stock. As of December 31, 1999, we had
warrants outstanding to purchase an aggregate of approximately 1,306,228 shares
of common stock resulting from our assumption of former Hiway warrants. The
exercise price for these warrants range from $3.53 to $3.85 per share. Holders
of these former Hiway warrants also are entitled to certain registration rights.
See "-- Registration Rights."

ANTI-TAKEOVER PROVISIONS

  Delaware Takeover Statute

     As a Delaware corporation, we are subject to the provisions of Section 203
of the Delaware General Corporation Law, as amended from time to time. Section
203 provides, with certain exceptions, that a publicly-held corporation is
prohibited from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder unless:

     - prior to such date, the board of directors of the corporation approved
       either the business combination or the transaction that resulted in the
       stockholder becoming an interested stockholder; or

     - upon consummation of the transaction that resulted in the stockholder
       becoming an interested stockholder, the interested stockholder owned at
       least 85% of the voting stock of the corporation outstanding at the time
       the transaction commenced, excluding for purposes of determining the
       number of shares outstanding those shares owned (x) by persons who are
       directors and also officers, and (y) by employee stock plans in which
       employee participants do not have the right to determine confidentially
       whether shares held subject to the plan will be tendered in a tender or
       exchange offer; or

     - at or subsequent to such date, the business combination is approved by
       the board of directors and authorized at an annual or special meeting of
       stockholders, and not by written consent, by the affirmative vote of at
       least 66 2/3% of the outstanding voting stock that is not owned by the
       interested stockholder.

     A "business combination" includes (1) any merger or consolidation involving
the corporation and the interested stockholder, (2) any sale, transfer, pledge
or other disposition of 10% or more of the assets of the corporation involving
the interested stockholder, (3) subject to certain exceptions, any transaction
that results in the issuance or transfer by the corporation of any stock of the
corporation to the interested stockholder, (4) any transaction involving the
corporation that has the effect of increasing the proportionate share of the
stock of any class or series of the corporation beneficially owned by the
interested stockholder, or (5) the receipt by the interested stockholder of the
benefit of any loans, advances, guarantees, pledges or other financial benefits
provided by or through the corporation. Subject to certain exceptions, an
"interested stockholder" is a person who, together with affiliates and
associates, owns, or within three years did own, 15% or more of the
corporation's voting stock. Section 203 could have the effect of delaying,
deterring or preventing a future takeover or change in control of Verio. It also
may render the removal of directors and management more difficult.

     In addition, our certificate of incorporation and bylaws, as amended and
restated, contain provisions that are intended to enhance the likelihood of
continuity and stability in the composition of our board and of the policies
formulated by our board which may discourage a future unsolicited takeover of
Verio. These provisions also may have the effect of discouraging or preventing
certain types of transactions involving an actual or threatened change of
control of Verio, including unsolicited takeover attempts, even though such a
transaction may offer our stockholders the opportunity to sell their stock at a
price above the prevailing market price.

  Restated Certificate of Incorporation and Bylaws

     Certain provisions of our certificate of incorporation and bylaws could
have the effect of discouraging potential acquisition proposals or making a
tender offer or delaying or preventing a change of control of Verio. In
particular, our certificate of incorporation and bylaws, as applicable, among
other things:

          (1) provide that all stockholder actions must be effected at a duly
     called meeting and not by a consent in writing, and an affirmative vote of
     the holders of 80% of our capital stock would be required to amend such
     provision;

                                       45
<PAGE>   51

          (2) provide that our board of directors will be divided into three
     classes of directors (disregarding the effect of any voting rights of
     holders of convertible preferred stock), as nearly equal in number as is
     reasonably possible, serving staggered terms so that directors' initial
     terms will expire at the first, second and third succeeding annual meeting
     of the stockholders following our initial public offering, respectively. At
     each such succeeding annual meeting, directors elected to succeed those
     directors whose terms are expiring at such meeting shall be elected for a
     three-year term of office. A vote of at least 80% of our capital stock
     would be required to amend such provision;

     We believe that a classified board of directors will help to assure the
continuity and stability of our board of directors and our business strategies
and policies, since a majority of the directors at any given time will have had
prior experience as directors of Verio. We also believe that this, in turn, will
permit our board of directors to more effectively represent the interest of
stockholders. With a classified board of directors, at least two annual meetings
of stockholders, instead of one, will generally be required to effect a change
in the majority of the board. As a result, a provision relating to a classified
board may discourage proxy contests for the election of directors or purchases
of a substantial block of our common stock because its provisions could operate
to prevent obtaining control of the board in a relatively short period of time.
Under Delaware law, a director on a classified board may be removed by the
stockholders of the corporation only for cause;

          (3) provide that special meetings of the stockholders may be called
     only by the President or, at the direction of the board, the Secretary of
     Verio. Advance written notice is required, which generally must be received
     by the Secretary not less than 30 days nor more than 60 days prior to the
     meeting, by a stockholder of a proposal or director nomination which such
     stockholder desires to present at a meeting of stockholders. Any amendment
     of this provision would require a vote of at least 80% of our capital
     stock;

          (4) does not include a provision for cumulative voting in the election
     of directors. Under cumulative voting, a minority stockholder holding a
     sufficient number of shares may be able to ensure the election of one or
     more directors. The absence of cumulative voting may have the effect of
     limiting the ability of minority stockholders to effect changes in the
     board and, as a result, may have the effect of deterring a hostile takeover
     or delaying or preventing changes in control or management of Verio;

          (5) provide that vacancies on our board may be filled by a majority of
     directors in office, although less than a quorum, and not by the
     stockholders; and

          (6) allow us to issue up to 5,300,000 shares of currently undesignated
     preferred stock with rights senior to those of the common stock and that
     otherwise could adversely affect the rights and powers, including voting
     rights, of the holders of common stock. In certain circumstances, such
     issuance could have the effect of decreasing the market price of the common
     stock, as well as having the anti-takeover effect discussed above.

     These provisions are intended to enhance the likelihood of continuity and
stability in the composition of our board and in the policies formulated by
them, and to discourage certain types of transactions that may involve an actual
or threatened change of control of Verio. These provisions are designed to
reduce our vulnerability to an unsolicited acquisition proposal and to
discourage certain tactics that may be used in proxy fights. However, such
provisions could have the effect of discouraging others from making tender
offers for our shares that could result from actual or rumored takeover
attempts. Such provision also may have the effect of preventing changes in our
management.

REGISTRATION RIGHTS

  Initial Investors

     Pursuant to a stockholders agreement we entered into with certain of our
initial investors, the initial investors are entitled to certain demand and
piggyback registration rights with respect to the registration of

                                       46
<PAGE>   52

certain registrable securities -- as defined in the stockholders
agreement -- held by the initial investors under the Securities Act. The initial
investors owning 25% or more of the registrable securities may require that we
register their registrable securities under the Securities Act, subject to the
right of the board to defer such registration for a period of up to 180 days. In
addition, if we propose to register securities under the Securities Act, other
than a registration statement on Form S-8 or S-4, whether or not for our own
account, then any of the initial investors has a right, subject to quantity
limitations determined by underwriters if the offering involves an underwriting,
to request that we register such investor's registrable securities. We will bear
all registration expenses incurred in connection with up to two long-form and
all short-form and piggyback registrations. Each initial investor will pay for
its own selling expenses on a pro rata basis. These registration rights are
subject to certain conditions and limitations, among them the right of the
underwriters of an offering to limit the number of shares included in such
registration.

  1997 Notes

     In connection with the issuance of the 1997 Notes, the holders of a number
of the warrants, warrant shares and registrable securities -- as defined in a
registration rights agreement entered into in connection with the issuance of
the 1997 Notes -- equivalent to a majority of the warrant shares subject to the
originally issued warrants, will be entitled to require Verio to effect one
registration under the Securities Act subject to certain limitations. These
holders also will have the right to include such registrable securities in any
registration statement under the Securities Act filed by Verio, other than:

          (1) a registration statement on Form S-8 or S-4;

          (2) a registration statement filed in connection with an offer of
     securities solely to existing security holders; or

          (3) a demand registration, whether or not for our own account.

     These registrations rights are subject to certain conditions and
limitations, among them the right of the underwriters of an offering to limit
the number of shares included in such registration.

  Nippon Telegraph and Telephone Corporation

     Pursuant to the investment agreement entered into with Nippon Telegraph and
Telephone Corporation, after May 15, 1999, Nippon Telegraph and Telephone
Corporation and any transferee of its rights may require, on up to three
occasions, that we effect a registration statement under the Securities Act with
respect to:

          (1) at least 25% of the shares of common stock that it purchased,
     including any securities issued or issuable by way of a distribution, stock
     split or the like -- which we refer to as the NTT Registrable Securities;
     or

          (2) NTT Registrable Securities with an anticipated aggregate net
     offering price of at least $25.0 million, unless we are eligible at such
     time to effect a registration statement on Form S-3, in which case the
     aggregate net offering price must be at least $15.0 million.

     We must effect any such registration as promptly as practicable, subject,
in certain circumstances, to our right to defer such demand for registration for
specified periods. In addition, if we propose to register our securities under
the Securities Act, or another holder of common stock exercises its demand
registration rights, then Nippon Telegraph and Telephone Corporation has a
right, subject to certain cutbacks determined by the underwriters in the event
of an underwritten offering, to include the NTT Registrable Securities in any
such offering. We will bear all registration expenses, subject to certain
exceptions, other than selling expenses which must be paid by Nippon Telegraph
and Telephone Corporation. In the event that any shares of our common stock that
it purchased are included in a registration statement, we have agreed to
indemnify Nippon Telegraph and Telephone Corporation against

                                       47
<PAGE>   53

certain losses for which Nippon Telegraph and Telephone Corporation may become
liable under the Securities Act.

  Hiway Acquisition

     In connection with our acquisition of Hiway, we entered into a registration
rights agreement with certain principal affiliate shareholders of Hiway. We also
agreed, as part of our assumption of the former Hiway warrants, to honor the
registration rights obligations contained in such warrants. In both cases, we
agreed to grant the specified shareholders and warrant holders certain piggyback
registration rights, and with regard to the certain warrant holders, demand
registration rights, with respect to the registration of certain registrable
securities -- as defined in the registration rights agreement and former Hiway
warrants -- under the Securities Act.

     If at any time we propose to register any common stock under the Securities
Act, then each specified shareholder and warrant holder has the right, subject
to certain limitations, including, to the extent applicable, certain specific
limitations addressed below, to request that we register its registrable
securities. With respect to certain warrant holders, this right does not apply
if we register on a Form S-8 or S-4, although with respect to certain other
warrant holders the piggyback registration right is inapplicable only when we
make a registration relating solely to employee benefit plans or a Rule 145
transaction. With respect to the specified shareholders, this piggyback
registration right does not apply if we register on a Form S-8 or S-4, or any
other form for a limited purpose, or any registration statement covering only
securities proposed to be issued in exchange for securities or assets of another
entity, in connection with an offering of our common stock.

     Pursuant to the terms of the former Hiway warrants, prior to the
effectiveness of any registration statement, we may terminate the filing or,
under the terms of certain former Hiway warrants, delay the effectiveness of the
applicable registration statement. Under the terms of the registration rights
agreement with the specified shareholders, subject to certain limitations, we
may delay the filing or effectiveness of, or suspend, the applicable
registration statement, and require that all specified shareholders immediately
cease sale of our common stock pursuant to the registration statement, in any
period during which we are engaged in any activity or transaction required to be
disclosed by Verio pursuant to the Securities Act.

     All these piggyback registration rights terminate upon the earlier to occur
of:

          (1) such time as all such registrable securities may be immediately
     sold pursuant to Rule 144 and/or (for the specified shareholders) Rule 145
     under the Securities Act within any 90-day period; or

          (2) upon any sale of such registrable securities pursuant to a
     registration statement or Rule 144 and/or (for the specified shareholders)
     Rule 145 under the Securities Act.

     We will bear all registration expenses, other than underwriting discounts
and commissions and, for the warrant holders, certain other expenses, incurred
in connection with any such registrations, except for any expenses of any
counsel retained by any specified shareholder or individual warrant holder in
connection with such registration.

     These registration rights are subject to certain limitations and
conditions. In particular, with regard to certain warrant holders, they may
register up to no more than 50% of their registrable securities in a particular
registration statement, depending upon the total number of shares of common
stock to be registered. Additionally, if the managing underwriter of an offering
seeks to limit the number of shares included in such offering, then the managing
underwriter may, with regard to certain warrant holders, limit or exclude such
warrant holders' registrable securities in the registration statement and, with
regard to certain other warrant holders, Verio shall include the shares sought
to be registered in the following order:

          (A) Verio and any holders of demand registration rights shall be
     entitled to register all securities that Verio or such holders propose to
     sell for their own account;

                                       48
<PAGE>   54

          (B) to the extent that inclusion would not have a material adverse
     effect, registrable securities of the warrant holders and other equity and
     debt securities requested for inclusion in the offering by holders of such
     other securities shall be included pro rata on the basis of the relative
     number of registrable securities, other equity securities and the principal
     amount of debt securities requested to be included in such offering.

     With regard to the specified shareholders, if the underwriters of an
offering seek to limit the number of shares included in such offering, then the
underwriters will apportion the shares sought to be registered as follows:

          (1) Verio and any holders of demand registration rights shall be
     entitled to register all securities that Verio or such holders propose to
     sell for their own account;

          (2) any holders of piggyback registration rights as and to the extent
     that such registration rights have priority over the registration rights
     granted to the specified shareholders; and

          (3) any specified shareholder, together with any holders of other
     piggyback registration rights as and to the extent that such piggyback
     registration rights rank equally with the piggyback registration rights
     granted to the specified shareholders, shall be entitled to register, on a
     proportionate basis, up to that number of registrable securities and other
     shares of common stock that is equal to the remaining shares of common
     stock that the lead managing underwriter will permit to be registered after
     giving effect to the apportionment in clauses (1) and (2) above, in
     connection with such offering. This is subject to any conflicting cut-back
     priority provided to MCI WorldCom pursuant to a registration rights
     agreement dated June 17, 1997 and based on the number of shares of common
     stock owned by each specified shareholder.

     Finally, certain warrant holders also retain the right to cause us to file
a shelf registration with respect to the registrable securities, provided that
(A) we shall only be required to effect one registration for all such warrant
holders possessing this right and (B) we shall not be required to effect such a
registration other than in accordance with Rule 415 on Form S-3.

                           FEDERAL TAX CONSIDERATIONS

     The following is a summary of certain material U.S. federal tax
considerations relevant to the purchase, ownership and disposition of our
convertible preferred stock and common stock. This summary is based on the
current provisions of the Internal Revenue Code of 1986, Treasury regulations
and judicial and administrative authority, all of which are subject to change,
possibly on a retroactive basis. This summary applies only to investors who hold
our convertible preferred stock or common stock as capital assets, within the
meaning of section 1221 of the Internal Revenue Code, and does not discuss the
tax consequences to special classes of investors, such as dealers in securities
or currencies, financial institutions, tax-exempt entities, life insurance
companies, persons holding our convertible preferred stock or common stock as a
part of a hedging, short sale or conversion transaction or a straddle, investors
whose functional currency is not the United States dollar, persons who hold our
convertible preferred stock or common stock through partnerships or other
pass-through entities, or, except as specifically noted, certain U.S.
expatriates. State, local and foreign tax consequences of ownership of our
convertible preferred stock and common stock are not summarized.

     We have not requested, and do not intend to request, any rulings from the
Internal Revenue Service concerning the federal tax consequences of an
investment in our convertible preferred stock or common stock. You are advised
to consult with your own tax advisor regarding the consequences of acquiring,
holding or disposing of our convertible preferred stock or common stock in light
of current tax laws, your particular investment circumstances, and the
application of state, local and foreign tax laws.

                                       49
<PAGE>   55

     When we refer in this summary to a "United States Holder," we mean a
beneficial owner of convertible preferred stock or common stock that is:

     - a citizen or resident of the United States for United States federal
       income tax purposes;

     - a corporation created or organized in the United States or under the laws
       of the United States or of any political subdivision thereof;

     - an estate whose income is includible in gross income for United States
       federal income tax purposes regardless of its source; or

     - a trust if a court within the United States is able to exercise primary
       supervision of the administration of the trust and one or more United
       States persons has the authority to control all substantial decisions of
       the trust.

     When we refer in this summary to a "Non-United States Holder," we mean a
beneficial owner of convertible preferred stock or common stock that is not a
United States Holder.

UNITED STATES HOLDERS

  Deposit Account

     Although there is no authority directly applicable to the treatment of the
deposit account, we believe that the treatment described below is appropriate
because the cash is intended to not be subject to the claims of our creditors,
and we will not be entitled to receive the cash in the deposit account except
under limited circumstances.

     Pursuant to the terms of the deposit agreement, each holder of convertible
preferred stock will be treated by us as owning a pro-rata portion of the cash
deposited in the deposit account. Accordingly, each holder of convertible
preferred stock should not treat its portion of the cash deposited in the
deposit account as part of the cost of the convertible preferred stock for
purposes of determining the holder's adjusted tax basis in such stock.

     Cash distributions of $0.8438 per share of convertible preferred stock on
each deposit payment date for each quarterly period should be treated as
withdrawals by the holders of the convertible preferred stock of amounts
deposited in the deposit account. Income earned on the cash deposited in the
deposit account, if any, should be included in income by each holder of shares
of convertible preferred stock pro rata in proportion to the number of shares of
convertible preferred stock held by such holder. Each holder should include such
amounts in income in the same manner as though the holder directly owned a pro
rata share of the cash in the deposit account. Distributions of common stock by
the deposit agent to the holders of the convertible preferred stock following
our election to transfer common stock to the deposit agent should be treated as
a purchase by each holder of convertible preferred stock of such common stock
for an amount equal to the convertible preferred stockholder's share of the cash
deposited in the deposit account allocated to such purchase. To the extent that
the fair market value of the common stock exceeds the amount paid for such
common stock, the excess should be treated as a distribution on the convertible
preferred stock.

     In the event that we exercise our right to have the deposit account paid to
us, the holders of the convertible preferred stock should be treated as having
made an additional payment to us with respect to their convertible preferred
stock, and, accordingly, should receive an increase in the tax basis of their
convertible preferred stock.

  Distributions

     We have the right to pay distributions on the convertible preferred stock
in cash or in shares of our common stock. If we distribute our common stock, the
amount of the distribution for federal income tax purposes will be the fair
market value of the common stock on the date the distribution is paid, and the
distribution will be subject to federal income tax to the same extent as a cash
distribution.

                                       50
<PAGE>   56

     A distribution on the convertible preferred stock or common stock will be
treated as a dividend to the extent of our current or accumulated earnings and
profits attributable to the distribution as determined under U.S. federal income
tax principles. The amount of our earnings and profits at any time will depend
upon our future actions and financial performance. If the amount of the
distribution exceeds our current and accumulated earnings and profits
attributable to the distribution, the distribution will be treated as a
nontaxable return of capital and will be applied against and reduce a holder's
adjusted tax basis in the convertible preferred stock, but not below zero. The
reduction in tax basis will increase the amount of any gain, or reduce the
amount of any loss, which a holder would otherwise realize on the sale or other
taxable disposition of the convertible preferred stock. If the distribution
exceeds both our current and accumulated earnings and profits attributable to
the distribution and a holder's adjusted tax basis in the convertible preferred
stock, the excess will be treated as capital gain and will be either long-term
or short-term capital gain depending on the holder's holding period for the
convertible preferred stock.

     Corporate investors in our convertible preferred stock generally should be
eligible for the 70% dividends-received deduction with respect to the portion of
any distribution on the stock taxable as a dividend. However, corporate
investors should consider certain provisions that may limit the availability of
a dividend received deduction, including the 46-day holding period required by
section 246(c) of the Internal Revenue Code, the rules of section 246A which
reduce the dividends-received deduction of dividends on certain debt-financed
stock, and the rules in section 1059 of the Internal Revenue Code that reduce
the basis of stock in respect of certain extraordinary dividends, as well as the
effect of the dividends-received deduction on the determination of alternative
minimum tax liability.

  Optional redemption for common stock or cash

     If we redeem our convertible preferred stock for common stock, the exchange
should constitute a recapitalization within the meaning of Section 368(a)(1)(E)
of the Internal Revenue Code. A holder will not recognize gain or loss on the
exchange unless some of the common stock is received in discharge of dividend
arrearages, in which case the redemption will be treated as a distribution on
the convertible preferred stock to the extent of the dividends in arrears. The
amount constituting a distribution will be taxed as a dividend to the extent of
our current or accumulated earnings and profits attributable to the distribution
at the time, in accordance with the treatment described above for distributions.
A holder's tax basis in our common stock received pursuant to the redemption
generally will equal that holder's tax basis in the convertible preferred stock
surrendered in exchange, and that holder's holding period for the common stock
generally will include the period the holder held the convertible preferred
stock. However, the tax basis of common stock received in discharge of dividend
arrearages will be its fair market value on the date received and the holding
period of that stock will commence on the day after its receipt.

     If we redeem our convertible preferred stock for cash, the redemption will
be taxable to a holder of the convertible preferred stock. The redemption
generally will be treated as a sale or exchange if the holder of the convertible
preferred stock does not own, actually or constructively within the meaning of
section 318 of the Internal Revenue Code, any stock of Verio other than the
redeemed convertible preferred stock. If the holder of the convertible preferred
stock does own, actually or constructively, other stock of Verio, a cash
redemption of the convertible preferred stock may be taxable in accordance with
the treatment described above for distributions. Such treatment as a
distribution will not apply if the redemption (1) is "substantially
disproportionate" with respect to the holder under section 302(b)(2) of the
Internal Revenue Code, or (2) is "not essentially equivalent to a dividend"
under section 302(b)(1) of the Internal Revenue Code. A distribution to a holder
will be "not essentially equivalent to a dividend" if it results in a meaningful
reduction in the holder's stock interest in Verio, which should be the case if
the holder's proportionate ownership interest, taking into account any actual
ownership of common stock and any stock constructively owned, is reduced, the
holder's relative stock interest in Verio is minimal, and the holder exercises
no control over our business affairs.

     If a cash redemption of a holder's convertible preferred stock is treated
as a sale or exchange, it will result in capital gain or loss equal to the
difference between the amount of cash received and the holder's adjusted tax
basis in the convertible preferred stock redeemed, except to the extent that the
redemption
                                       51
<PAGE>   57

price includes unpaid dividends which we declare prior to the redemption. The
capital gain or loss will be long term if the holder has held the convertible
preferred stock for more than one year. Any cash the holder receives in
discharge of dividend arrearages on the convertible preferred stock will be
treated as a distribution on the convertible preferred stock to the extent of
the dividends in arrears, taxable in accordance with the treatment described
above for distributions.

     If the cash a holder receives on redemption of the convertible preferred is
taxed as a dividend, the tax basis (reduced for amounts, if any, treated as
return of capital) in the redeemed convertible preferred stock will be
transferred to any remaining other Verio stock the holder owns, subject, in the
case of a corporate taxpayer, to reduction or possible gain recognition under
section 1059 of the Internal Revenue Code in an amount equal to the nontaxed
portion of such dividend. If a holder does not actually own any other Verio
stock, having a remaining stock interest only constructively, the holder may
lose the benefit of its tax basis in the convertible preferred stock but the tax
basis may be shifted to the stock of the related person whose stock the holder
constructively owns.

     Under some circumstances, section 305(c) of the Internal Revenue Code
requires that any excess of the redemption price of preferred stock over its
issue price be treated as constructively distributed on a periodic basis prior
to actual receipt. However, these rules do not apply if you and Verio are not
"related" within the meaning of Treasury regulations under section 305(c), there
are no plans, arrangements or agreements that effectively require or are
intended to compel us to redeem the convertible preferred stock, and our
exercise of the right to redeem would not reduce the yield of the convertible
preferred stock, as determined under the regulations. We intend to take the
position that the existence of our optional redemption rights does not result in
a constructive distribution under section 305(c). The preferred stock will also
be issued with a liquidation premium, since the liquidation preference will
exceed the proceeds received by Verio after excluding amounts deposited in the
deposit account. Although the regulations under section 305(c) do not
specifically address the treatment of liquidation premiums, we believe that a
similar rationale should apply to such premiums.

  Conversion

     A holder of our convertible preferred stock generally will not recognize
gain or loss on conversion of shares of convertible preferred stock into our
common stock, except with respect to any cash paid in lieu of fractional shares
of common stock. However, a holder may recognize gain or dividend income to the
extent there are dividends in arrears on the stock at the time of conversion
into common stock. A holder's tax basis in the common stock received upon
conversion of convertible preferred stock generally will be equal to the
holder's tax basis in the converted preferred stock and the holding period of
the common stock generally will include the holder's holding period for the
converted preferred stock. However, the tax basis of any common stock received
on conversion which is treated as a dividend will be equal to its fair market
value on the date of the distribution and the holding period of that common
stock will commence on the day after its receipt.

     A holder of our convertible preferred stock may be deemed to have received
a constructive distribution of stock taxable as a dividend if the conversion
ratio of the convertible preferred stock is adjusted to reflect a cash or
property distribution on our common stock or to prevent dilution in the case of
certain issuances of rights or warrants to purchase common stock at below market
prices. Although an adjustment to the conversion price made pursuant to a bona
fide reasonable adjustment formula which has the effect of preventing the
dilution of a holder's interest in Verio generally will not be considered to
result in a constructive distribution of stock, some of the possible adjustments
may trigger this rule. If a nonqualifying adjustment is made, or if we fail to
make an adjustment in some cases, a holder might be deemed to have received a
taxable stock dividend. If so, the amount of the dividend to be included in
income would be the fair market value of the additional common stock to which a
holder would be entitled by reason of the increase in the holder's proportionate
equity interest in Verio.

                                       52
<PAGE>   58

  Sale or other taxable disposition

     If a holder sells or disposes of convertible preferred stock or common
stock in a taxable transaction other than a redemption or conversion by us, the
holder will recognize capital gain or loss equal to the difference between the
amount of cash and the fair market value of property received and the holder's
tax basis in the convertible preferred stock or common stock. The gain or loss
will be long-term capital gain or loss if the holder's holding period for the
stock exceeds one year. For corporate taxpayers, long-term capital gains are
taxed at the same rate as ordinary income. For individual taxpayers, net capital
gains -- the excess of the taxpayer's net long-term capital gains over net
short-term capital losses -- are subject to a maximum tax rate of 20% if the
stock is held for more than one year.

NON-UNITED STATES HOLDERS

  Deposit Account

     Because we will treat cash distributions from the deposit account as
non-taxable withdrawals, a Non-United States Holder generally will not be
subject to United States tax on these distributions. Distributions from the
deposit account attributable to interest earned on amounts held in the deposit
account and invested in United States government obligations also should be
exempt from United States withholding tax as portfolio interest provided that
the Non-United States Holder provides us a properly completed Internal Revenue
Service Form W-8.

  Distributions

     Distributions received by a holder as a Non-United States Holder in respect
of the convertible preferred stock, whether in cash or shares of common stock,
and distributions in respect of common stock, to the extent considered dividends
for U.S. federal income tax purposes, generally will be subject to withholding
of United States federal income tax at a 30% rate or such lower rate as may be
specified by an applicable income tax treaty, unless the dividend is effectively
connected with the holder's conduct of a trade or business within the United
States or, where a tax treaty applies, is attributable to a United States
permanent establishment the holder maintains. If the dividend is effectively
connected with a holder's conduct of a trade or business within the United
States or, where a tax treaty applies, is attributable to a holder's United
States permanent establishment, the dividend will be subject to federal income
tax on a net income basis at applicable graduated individual or corporate rates
and will be exempt from the 30% withholding tax.

     In addition to the graduated rate described above, dividends received by a
corporate Non-United States Holder that are effectively connected with a United
States trade or business or, where a tax treaty applies, is attributable to a
holder's United States permanent establishment, may, under some circumstances,
be subject to an additional "branch profits tax" at a 30% rate or at a lower
rate specified by an applicable income tax treaty.

     For purposes of obtaining a reduced rate of withholding under an income tax
treaty, a holder will be required to provide certain information concerning the
holder's country of residence and entitlement to tax treaty benefits. If a
holder claims exemption from withholding with respect to dividends effectively
connected with the holder's conduct of a business within the United States, the
holder must provide appropriate certification, currently, Internal Revenue
Service Form 4224, to Verio or its paying agent. If a holder is eligible for a
reduced rate of U.S. federal withholding tax, the holder may obtain a refund of
any excess withheld amounts by timely filing an appropriate claim for refund.

     If a distribution exceeds our current and accumulated earnings and profits
attributable to the distribution, it will be treated first as a return of a
holder's tax basis in the stock to the extent of the holder's basis and then as
gain from the sale of a capital asset which would be taxable as described below.
Any withholding tax on distributions in excess of our current and accumulated
earnings and profits is refundable to a holder upon the timely filing of an
appropriate claim for refund with the Internal Revenue Service.

     Under currently applicable Treasury regulations, dividends paid to an
address outside the United States are presumed to be paid to a resident of such
country, unless the payor has knowledge to the contrary, for purposes of the
withholding discussed above, and, under the current interpretation of these
Treasury regulations, for purposes of determining the applicability of a tax
treaty rate. Under Treasury regulations currently scheduled to be effective with
respect to dividends paid after December 31, 2000, a Non-United States Holder of
Verio stock who wishes to claim the benefit of an applicable treaty rate, and to
avoid backup withholding as discussed below, will be required to satisfy
applicable certification and other requirements.

  Disposition of convertible preferred stock or common stock

     Generally, a holder will not be subject to United States federal income tax
on any gain recognized upon the sale or other disposition of convertible
preferred stock or common stock. However, a holder will be subject to federal
income tax on the gain if:

          (1) the gain is effectively connected with your United States trade
     or, if a tax treaty applies, attributable to a holder's United States
     permanent establishment;

          (2) a holder is an individual who is a former citizen of the United
     States who lost such citizenship within the preceding ten-year period, or
     former long-term resident of the United States who relinquished United
     States residency on or after February 6, 1995, and the loss of citizenship
     or permanent residency had as one of its principal purposes the avoidance
     of United States tax; or

          (3) a holder is a non-resident alien individual, is present in the
     United States for 183 days or more days in the taxable year of disposition
     and either (a) have a "tax home" in the United States for United States
     federal income tax purposes or (b) the gain is attributable to an office or
     other fixed place of business the holder maintains in the United States.

     A holder of our convertible preferred stock will also be subject to federal
income tax on the gain from sale of our convertible preferred stock if we are or
have been a "United States real property holding corporation" -- which we refer
to in this prospectus as USRPHC -- within the meaning of section 897(c)(2) of
the Internal Revenue Code at any time the holder held the stock, or within the
five-year period preceding the sale of the stock if the holder holds the stock
for more than five years. A holder would also be subject to federal income tax
on sale of our common stock if we were a USRPHC during the specified time
periods; however, since our common stock is traded on an established securities
market, a holder would be subject to tax only if the holder holds, directly or
indirectly, common stock with a fair market value in excess of 5% of the fair
market value of all Verio common stock outstanding. Verio believes it is not now
a USRPHC, that it has not been an USRPHC at any time since it was formed, and
that it is unlikely to become a USRPHC. Nevertheless, since our convertible
preferred stock will not be traded on an established securities market, on the
sale or other taxable disposition of our convertible preferred stock, the
purchaser would be required to withhold 10% of the proceeds of such disposition,
unless Verio were to provide a certification that it is not a USRPHC, and has
not been a USRPHC during a specific period, or another exemption applied.

  Redemption and conversion of convertible preferred stock

     As a Non-United States Holder, the holder generally will not recognize any
gain or loss for United States federal income tax purposes upon conversion of
convertible preferred stock into common stock, except with respect to any cash
paid in lieu of fractional shares of common stock, which would be subject to the
rules described under "Disposition of convertible preferred stock or common
stock." However, the holder may recognize gain or dividend income to the extent
there are dividends in arrears on the convertible preferred stock at the time of
conversion into common stock.

     A redemption of convertible preferred stock for cash will be an event which
will constitute either a dividend to the extent of our current and accumulated
earnings and profits or a sale or exchange. See "United States
Holders -- Optional redemption for common stock or cash." To the extent the
redemption
                                       54
<PAGE>   60

is treated as a dividend, the tax consequences are described in "Non-United
States Holders -- Distributions," and to the extent the redemption is treated as
a sale or exchange, the tax consequences are described in "Non-United States
Holders -- Disposition of convertible preferred stock or common stock."

  Federal estate taxes

     If a holder is an individual Non-United States Holder, convertible
preferred stock or common stock the holder holds or is treated as owning at the
time of the holder's death will be included in the holder's United States gross
estate for United States federal estate tax purposes and may be subject to
United States federal estate tax, unless an applicable estate tax treaty
provides otherwise.

INFORMATION REPORTING AND BACKUP WITHHOLDING

     Verio generally will be required to report to some holders of its
convertible preferred stock or common stock and to the Internal Revenue Service
the amount of any dividends paid to the holder in each calendar year and the
amounts of tax withheld, if any, with respect to these payments. Copies of the
information returns reporting these dividends and withholding may also be made
available to the tax authorities in the country in which a Non-United States
Holder resides under the provisions of an applicable income tax treaty.

     Each holder of convertible preferred stock or common stock -- other than an
exempt holder such as a corporation, tax-exempt organization, qualified pension
or profit-sharing trust, individual retirement account, or a nonresident alien
individual who provides certification as to his or her status as a
nonresident -- will be required to provide, under penalties of perjury, a
certification setting forth the holder's name, address, correct federal taxpayer
identification number and a statement that the holder is not subject to backup
withholding. If a nonexempt holder fails to provide the required certification,
we will be required to withhold 31% of the amount otherwise payable to the
holder, and remit the withheld amount to the Internal Revenue Service as a
credit against the holder's federal income tax liability. You should consult
your own tax advisor regarding your qualification for exemption from backup
withholding and the procedure for obtaining any applicable exemption.

     Payment of the proceeds of a sale of convertible preferred stock or common
stock by or through a United States office of a broker is subject to both backup
withholding and information reporting unless the beneficial owner certifies
under penalties of perjury that it is a Non-United States Holder or otherwise
establishes an exemption. In general, backup withholding and information
reporting will not apply to a payment of the proceeds of a sale of convertible
preferred stock or common stock by or through a foreign office of a broker. If,
however, such broker is, for United States federal income tax purposes a United
States person, a "controlled foreign corporation" for U.S. federal tax purposes,
or a foreign person that derives 50% or more of its gross income for a certain
period from the conduct of a trade or business in the United States, or, for
taxable years beginning after December 31, 2000, a foreign partnership in which
one or more United States persons, in the aggregate, own more than 50% of the
income or capital interests in the partnership or if the partnership is engaged
in a trade or business in the United States, these payments will be subject to
information reporting, but not backup withholding, unless (1) the broker has
documentary evidence in its records that the beneficial owner is a Non-United
States Holder and some other conditions are met, or (2) the beneficial owner
otherwise establishes an exemption.

     Any amounts withheld under the backup withholding rules may be allowed as a
refund or a credit against the holder's United States federal income tax
liability provided the required information is furnished to the Internal Revenue
Service.

THE FOREGOING DISCUSSION IS FOR GENERAL INFORMATION AND IS NOT TAX ADVICE.
ACCORDINGLY, EACH PROSPECTIVE HOLDER OF CONVERTIBLE PREFERRED STOCK OR COMMON
STOCK SHOULD CONSULT ITS TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES TO IT
OF THE CONVERTIBLE PREFERRED STOCK AND COMMON STOCK, INCLUDING THE APPLICABILITY
AND EFFECT OF ANY STATE, LOCAL OR FOREIGN INCOME TAX LAWS, AND ANY RECENT OR
PROSPECTIVE CHANGES IN APPLICABLE TAX LAWS.

                              PLAN OF DISTRIBUTION

  Secondary Offering

     We will not receive any proceeds from any sales of the convertible
preferred stock or common stock by selling stockholders. The shares of common
stock issuable by us in lieu of cash as dividends on the convertible preferred
stock and the shares of common stock issuable by us at our option through, at
the latest, August 1, 2000, in exchange for funds held in the deposit account on
behalf of the holders of the convertible preferred stock may be issued by us to
holders of record of the convertible preferred stock in accordance with the
terms under which the convertible preferred stock has been issued. See
"Description of the Series A Convertible Preferred Stock -- Deposit Account" and
"Description of the Series A Convertible Preferred Stock -- Dividends".

     Shares of our convertible preferred stock and common stock held by the
selling stockholders and covered by this prospectus and, if applicable, any
prospectus supplement may be offered and sold from time to time by the selling
stockholders in one or more transactions. These transactions may involve crosses
or block transactions. The selling stockholders will act independently of us in
making decisions with respect to the timing, manner and size of each sale. The
selling stockholders, which term includes their transferees, pledgees or donees
or their successors, may sell the shares being offered here as follows:

     - on any of the United States securities exchanges or quotation services
       where the convertible preferred stock or common stock is listed or quoted
       at the time of sale, including the Nasdaq National Market where our
       common stock is listed;

     - in transactions otherwise than on the exchanges or services described
       above;

     - in the over-the-counter market;

     - in negotiated transactions or otherwise, including an underwritten
       offering;

     - in connection with short sales of our shares;

     - by pledge or by grant of a security interest in the shares to secure
       debts and other obligations;

     - through the writing of options, whether the options are listed on an
       options exchange or otherwise;

     - in connection with the writing of non-traded and exchange-traded call
       options or put options, in hedge transactions and in settlement of other
       transactions in standardized or over-the-counter options;

     - through the distribution of the shares by any selling stockholder to its
       partners, members or stockholders; or

     - in a combination of any of the above transactions.

     In connection with the sale of the convertible preferred stock or common
stock or otherwise, the selling stockholders may enter into hedging transactions
with broker-dealers or other financial institutions. These broker-dealers or
other financial institutions may in turn engage in short sales of the
convertible preferred stock or common stock and deliver these securities to
close out these short positions. They also may loan or pledge the convertible
preferred stock or common stock to broker-dealers that in turn may sell these
securities.

     The selling stockholders may sell their shares at market prices prevailing
at the time of sale, at prices related to the prevailing market prices, at
negotiated prices or at fixed prices. Each of the selling stockholders reserves
the right to accept and, together with their agents from time to time, to
reject, in whole or in part, any proposed purchase of the convertible preferred
stock or common stock to be made directly or through agents.

                                       56
<PAGE>   62

     The selling stockholders are subject to the provisions of the Exchange Act
of 1934, as amended, and the rules under it relating to stock manipulation,
particularly Regulation M. They are not to engage in any transaction in
violation of these provisions.

     The selling stockholders may sell their shares directly to purchasers or
may use underwriters, broker-dealers or agents to sell their shares.
Underwriters, broker-dealers or agents who sell the shares may receive
compensation in the form of discounts, concessions, or commissions from the
selling stockholders or they may receive compensation from purchasers of the
shares for whom they acted as agents or to whom they sold the shares as
principal, or both. The compensation as to a particular underwriter, broker-
dealer or agent will not be in excess of eight percent (8%) of the selling price
of the shares sold by the particular underwriter, broker-dealer or agent. The
selling stockholders and any underwriters, broker-dealers or agents that
participate in the sale of their convertible preferred stock or common stock may
be deemed to be "underwriters" within the meaning of the Securities Act of 1933,
as amended. Any discounts, commissions, concessions or profits received by these
underwriters, broker-dealers or agents on any resale of the shares may be
underwriting discounts and commissions under the Securities Act of 1933, as
amended. Selling stockholders who are "underwriters" within the meaning of the
Securities Act of 1933, as amended, will be subject to the prospectus delivery
requirements of the Securities Act.

     Those selling stockholders identified as broker-dealers are statutory
underwriters within the meaning of the Securities Act when those broker-dealers
sell shares of our convertible preferred stock or common stock and such stock
was not acquired initially by such broker-dealers as compensation for
underwriting activities.

     We will pay all fees and expenses incurred in connection with preparing and
filing this prospectus and any prospectus supplement and the registration
statement and any amendments thereto. The selling stockholders will pay any
brokerage commissions and similar selling expenses, if any, attributable in
connection with the sale of the shares of common stock, including stock transfer
taxes due or payable in connection with the sale of the shares.

     We have agreed to keep the registration statement, of which this prospectus
and any subsequent prospectus supplements constitute a part, effective until all
of the securities covered by this registration statement may be freely sold by
the selling stockholders without registration pursuant to Rule 144(k) of the
Securities Act, assuming none of the selling stockholders is an affiliate of
Verio. However, with regard to BI Partners LLC and Donald Gene Smith, on the one
hand, and Merrill Lynch, Pierce, Fenner & Smith Incorporated and NMS Services
(Cayman) Inc., on the other hand, we have agreed only to keep the registration
statement effective as to our common stock for at least 180 days in the case of
the former and 120 days in the case of the latter. For Merrill Lynch, Pierce,
Fenner & Smith Incorporated, this latter limitation only applies to the extent
that the common stock it holds was not received as a result of converting our
convertible preferred stock to common stock. There can be no assurance that the
selling stockholders will sell all or any of the shares of convertible preferred
stock or common stock offered here.

     Under the securities laws of certain states, the securities may be sold in
such states only through registered or licensed brokers or dealers.

     Selling stockholders may also resell all or a portion of their securities
in open market transactions in reliance upon Rule 144 under the Securities Act
of 1933, as amended. However, to do so, they must meet the criteria and conform
to the requirements of that Rule. In addition, any securities covered by this
prospectus which qualify for sale pursuant to Rule 144A of the Securities Act,
as amended, may be sold under Rule 144A rather than pursuant to this prospectus.
A selling stockholder may not sell any convertible preferred stock or common
stock by means other than as described in this prospectus.

     In all but one case, we have entered into registration rights agreements
and/or obligations for the benefit of the selling stockholders to register their
convertible preferred stock and/or common stock under applicable federal and
state securities laws under various circumstances and at various times. Pursuant
to these registration rights agreements and obligations, we have agreed to
indemnify the selling stockholders, and the selling stockholders have agreed to
indemnify us, and each of us has agreed to indemnify other

                                       57
<PAGE>   63

persons named and/or described in the registration rights agreements and
obligations, in each case against various liabilities, including some
liabilities arising under the Securities Act of 1933, as amended, in connection
with the offer and sale of the convertible preferred stock and common stock by
the selling stockholders. These indemnification obligations of ours and the
selling stockholders generally include obligations to indemnify each underwriter
(if any) that participates in the offering or sale of the convertible preferred
stock and/or common stock by the selling stockholders and each person (if any)
who controls each underwriter.

  Primary Offering

     We and/or Verio, LLC may sell our common stock pursuant to any applicable
prospectus supplement directly to one or more purchasers or though agents or
underwriters. We and/or Verio, LLC may sell our common stock pursuant to any
applicable prospectus supplement in at-the-market equity offerings or on a
negotiated or competitive bid basis through underwriters or dealers or directly
to other purchasers or through agents. We will name any underwriter or agent
involved in the offer and sale of the securities in the applicable prospectus
supplement.

     We and/or Verio, LLC may distribute the securities from time to time in one
or more transactions:

     - at a fixed price or prices, which may be changed;

     - at market prices prevailing at the time of sale;

     - at prices related to prevailing market prices; or

     - at negotiated prices.

     We and/or Verio, LLC also may, from time to time, authorize underwriters
acting as our agents to offer and sell our common stock upon the terms and
conditions as set forth in the applicable prospectus supplement. In connection
with the sale of our common stock, underwriters may be deemed to have received
compensation from us in the form of underwriting discounts or commissions and
may also receive commissions from purchasers of the common stock for whom they
may act as agent. Underwriters may sell the common stock to or through dealers,
and dealers may receive compensation in the form of discounts, concessions or
commissions from the underwriters and/or commissions from the purchasers for
whom they may act as agent.

     We will describe in the applicable prospectus supplement any underwriting
compensation we and/or Verio, LLC pay to underwriters or agents in connection
with the offering of our common stock, and any discounts, concessions or
commissions allowed by underwriters to participating dealers. Dealers and agents
participating in the distribution of our common stock may be deemed to be
underwriters, and any discounts and commissions received by them and any profit
realized by them on resale of our common stock may be deemed to be underwriting
discounts and commissions. We and/or Verio, LLC may enter into agreements to
indemnify underwriters, dealers and agents against certain civil liabilities,
including liabilities under the Securities Act, and to reimburse these persons
for certain expenses. We will describe any indemnification agreements in the
applicable prospectus supplement.

     Any shares of common stock sold by us and/or Verio, LLC pursuant to a
prospectus supplement may be listed on the NASDAQ National Market System,
subject to official notice of issuance.

     If indicated in the applicable prospectus supplement, we and/or Verio, LLC
may authorize dealers acting as our agents to solicit offers by certain
institutions to purchase our common stock at the public offering price set forth
in the prospectus supplement pursuant to delayed delivery contracts providing
for payment and delivery on the date or dates stated in the prospectus
supplement. We and/or Verio, LLC may make delayed delivery with various
institutions, including commercial and savings banks, insurance

                                       58
<PAGE>   64

companies, pension funds, investment companies and educational and charitable
institutions. Delayed delivery contracts will not be subject to any conditions
except:

     - the purchase by an institution of our common stock covered by its delayed
       delivery contracts shall not at the time of delivery be prohibited under
       the laws of any jurisdiction in the United States to which the
       institution is subject; and

     - if our common stock is sold to underwriters, we and/or Verio, LLC shall
       have sold to the underwriters the total principal amount of the offered
       common stock less the principal amount covered by the delayed delivery
       contracts.

     To facilitate the offering of our common stock, some persons participating
in the offering may engage in transactions that stabilize, maintain, or
otherwise affect the price of our common stock. This may include over-allotments
or short sales of the common stock, which involves the sale by persons
participating in the offering of more common stock than we and/or Verio, LLC
sold to them. In these circumstances, these persons would cover the
over-allotments or short positions by making purchases in the open market or by
exercising their over-allotment option. The effect of these transactions may be
to stabilize or maintain the market price of the securities at a level above
that which might otherwise prevail in the open market. These transactions may be
discontinued at any time.

     Certain of the underwriters and their affiliates may be customers of,
engage in transactions with and perform services for, us in the ordinary course
of business.

                                 LEGAL OPINIONS

     The validity of the shares of convertible preferred stock and common stock
offered hereby will be passed upon by Morrison & Foerster LLP, San Francisco,

                  WHERE YOU CAN FIND MORE INFORMATION ABOUT US

     We have filed with the Securities and Exchange Commission, or the SEC, a
registration statement on Form S-3 under the Securities Act of 1933. This
prospectus and any subsequent prospectus supplements do not contain all of the
information in the registration statement. We have omitted from this prospectus
some parts of the registration statement, as permitted by the rules and
regulations of the SEC. This prospectus provides you only with a general
description of the offered securities. Each time offered securities are to be
sold, we will provide, if and so far as required, a prospectus supplement that
will contain specific information about the terms of that offering. The
prospectus supplement may also add, update or change any information contained
in this prospectus. You should read both this prospectus and any prospectus
supplement together with the additional information described under this
heading.

     We file annual, quarterly and special reports, proxy statements and other
information with the SEC. You may inspect and copy the registration statement,

disclose important information to you by referring you to another document filed
separately with the SEC. This prospectus incorporates by reference documents
which are not presented in this prospectus or delivered to you with it. The
information incorporated by reference is an important part of this prospectus
and any subsequent prospectus supplement. Information that we file subsequently
with the SEC will automatically update this prospectus and any outstanding
prospectus supplements. We incorporate by reference the documents listed below
and amendments to them. These documents and their amendments were previously
filed with the SEC. These documents contain important information about us and
our finances. The information in some of these documents was provided prior to
our two-for-one stock split completed on August 20, 1999. Accordingly, all share
numbers and operative share price information in these documents, where
appropriate, should be adjusted to give effect to the stock split.
