Telephone Corporation, a limited liability joint stock company incorporated
under the laws of Japan ("NTT"), disclosed in a Tender Offer Statement on
Schedule TO, dated May 17, 2000 (the "Schedule TO"), to purchase all of the
issued and outstanding shares of Common Stock (other than shares of Common

price of $60.00 per share, net to the seller in cash, without interest
thereon, and all of the issued and outstanding shares of Preferred Stock at a

Information Statement is incorporated by reference herein.

The Merger Agreement.

  The following is a summary of the Merger Agreement, which summary is
qualified in its entirety by reference to the Merger Agreement, which is filed
as Exhibit (e)(1) hereto. Capitalized terms not otherwise defined herein have
the meanings set forth in the Merger Agreement.

  The Offer. The Merger Agreement provides for the commencement of the Offer
by Purchaser. The obligation of Purchaser to accept for payment and pay for
Shares validly tendered pursuant to the Offer is subject to the prior
satisfaction or waiver by Purchaser of the conditions to the Offer set forth
below. The Merger Agreement provides that, without the prior written consent
of Verio, Purchaser will not (a) reduce the number of Shares subject to the
Offer, (b) reduce the Offer Price or the Preferred Offer Price, (c) impose
additional conditions to the Offer other than the conditions set forth below
or modify the conditions to the Offer (other than waive any condition of the
Offer to the extent permitted by the Merger Agreement), (d) except as
described in the next two paragraphs, extend the Offer, (e) change the form of
consideration payable in the Offer, or (f) amend any other term of the Offer
in a manner adverse to the holders of Shares.

  Purchaser and NTT Communications have agreed with Verio that they will not
extend the Offer, without the consent of Verio, provided, however, that
without the consent of Verio, Purchaser and NTT Communications may extend the
Offer (a) if, at the scheduled or extended expiration date of the Offer any of
the conditions to Purchaser's obligation to accept Shares for payment are not
satisfied or waived, until such time as such conditions are satisfied or
waived, (b) for any period reasonably determined by Purchaser after
consultation with its legal advisors to be required by any rule, regulation,
interpretation or position of the Securities and Exchange Commission (the
"SEC") or the staff thereof applicable to the Offer and (c) if all of the
conditions to the Offer are satisfied or waived but the sum of the number of
shares of Common Stock tendered pursuant to the Offer and the number of shares
of Common Stock owned by NTT Communications or one or more direct or indirect
subsidiaries of NTT Communications is less than 90% of the outstanding shares
of Common Stock but at least

                                       2
<PAGE>

85% of the outstanding shares of Common Stock, on one or more occasions for an
aggregate period of not more than five business days beyond the latest
expiration date that would otherwise be permitted under the terms of the
Merger Agreement (provided that all conditions to the Offer should be
irrevocably deemed to have been satisfied or waived if we elect to extend the
Offer pursuant to clause (c) of this sentence).

  Purchaser and NTT Communications have also agreed with Verio that if at any
scheduled expiration date of the Offer, the Minimum Condition (as defined
below in "--Conditions of the Offer") or the conditions to the Offer relating
to the HSR Act or the Exon-Florio Amendment (each as defined in Item 8) or the
conditions to the Offer described in paragraph (e) or (f) of "--Conditions of
the Offer" below shall not have been satisfied but all other conditions to the
Offer shall then be satisfied, or if not satisfied, be reasonably capable of
being satisfied prior to November 10, 2000, at the request of Verio, Purchaser
and NTT Communications will extend the Offer from time to time (each such
extension not to exceed 10 business days after the previously scheduled
expiration date of the Offer unless agreed upon by Verio, NTT Communications
and Purchaser), subject to any right of NTT Communications, Purchaser or Verio
to terminate the Merger Agreement pursuant to its terms.

  Conditions of the Offer. Notwithstanding any other term of the Offer or the
Merger Agreement, Purchaser shall not be required to accept for payment or,
subject to any applicable rules and regulations of the SEC, including Rule
14e-1(c) under the Exchange Act (relating to Purchaser's obligation to pay for
or return tendered Shares after the termination or withdrawal of the Offer),
to pay for any Shares tendered pursuant to the Offer unless (i) there shall
have been validly tendered and not withdrawn prior to the expiration of the
Offer such number of shares of Common Stock that, together with the shares of
Common Stock then owned by NTT Communications and its subsidiaries, would
constitute at least a majority of the shares of Common Stock that in the
aggregate are outstanding determined on a fully diluted basis (assuming the
exercise of all options to purchase shares of Common Stock, and the conversion
or exchange of all securities convertible or exchangeable into shares of
Common Stock, outstanding at the expiration date of the Offer) (the "Minimum
Condition"), (ii) any waiting period under the HSR Act applicable to the
purchase of Shares pursuant to the Offer shall have expired or been terminated
prior to the expiration date of the Offer, and (iii) the period of time for
any applicable review process by CFIUS (as defined in Item 8) under the Exon-
Florio Amendment shall have expired and CFIUS shall not have taken any action
or made any recommendation to the President of the United States to block or
prevent the consummation of the Offer or the Merger. Furthermore,
notwithstanding any other term of the Offer or the Merger Agreement, Purchaser
shall not be required to accept for payment or, subject as aforesaid, to pay
for any Shares not theretofore accepted for payment or paid for, and may
terminate the Offer if, at any time on or after the date of the Merger
Agreement and before the acceptance of such Shares for payment or the payment
therefor, any of the following conditions exists (other than as a result of
any action or inaction of NTT Communications or any of its subsidiaries that
constitutes a breach of the Merger Agreement):

    (a) there shall be threatened or pending by any Governmental Entity (as
  defined in the Merger Agreement) any suit, action or proceeding (i)
  challenging the acquisition by NTT Communications or Purchaser of any
  Shares under the Offer, seeking to restrain or prohibit the making or
  consummation of the Offer or the Merger or the performance of any of the
  other transactions contemplated by the Merger Agreement, or seeking to
  obtain from Verio, NTT Communications or Purchaser any damages that, if
  awarded, would have a Material Adverse Effect (as defined below) on Verio,
  (ii) seeking to prohibit or materially limit the ownership or operation by
  Verio, NTT Communications or any of their respective subsidiaries of a
  material portion of the business or assets of Verio and its subsidiaries,
  taken as a whole, or NTT Communications and its subsidiaries, taken as a
  whole, or to compel Verio or NTT Communications to dispose of or hold
  separate any material portion of the business or assets of Verio and its
  subsidiaries, taken as a whole, or NTT Communications and its subsidiaries,
  taken as a whole, in each case, as a result of the Offer or any of the
  other transactions contemplated by the Merger Agreement, (iii) seeking to
  impose material limitations on the ability of NTT Communications or
  Purchaser to acquire or hold, or exercise full rights of ownership of, any
  shares of Common Stock to be accepted for payment pursuant to the Offer,
  including the right to vote such shares of Common Stock on all matters
  properly presented to the stockholders of Verio, (iv) seeking to prohibit
  NTT Communications or any of its subsidiaries from effectively controlling
  in any material respect any material portion of the business or operations
  of Verio or

                                       3
<PAGE>

  its subsidiaries or (v) which otherwise is reasonably likely to have a
  Material Adverse Effect on Verio, or there shall be pending by any other
  person any suit, action or proceeding which would have a Material Adverse
  Effect on Verio;

    (b) there shall be enacted, entered, enforced, promulgated or deemed
  applicable to the Offer or the Merger by any Governmental Entity any
  statute, rule, regulation, judgment, order or injunction, other than the
  application to the Offer or the Merger of applicable waiting periods under
  the HSR Act or any applicable waiting periods under any foreign laws
  enacted as of the date of the Merger Agreement, that is reasonably likely
  to result, directly or indirectly, in any of the consequences referred to
  in clauses (i) through (v) of paragraph (a) above;

    (c) there shall have occurred any Material Adverse Change (as defined
  below) with respect to Verio;

    (d) (i) the Verio Board or any committee thereof shall have withdrawn or
  modified in a manner adverse to NTT Communications or Purchaser its
  approval or recommendation of the Offer, the Merger or the Merger
  Agreement, or approved or recommended any Takeover Proposal or (ii) the
  Verio Board or any committee thereof shall have resolved to take any of the
  foregoing actions;

    (e) the representations and warranties of Verio set forth in the Merger
  Agreement shall not be true and correct in each case at the date of the
  Merger Agreement and at the scheduled or extended expiration of the Offer
  unless the inaccuracies (without giving effect to any materiality or
  Material Adverse Effect qualifications or exceptions contained therein)
  under such representations and warranties, taking all the inaccuracies
  under such representations and warranties together in their entirety, do
  not, individually or in the aggregate, result in a Material Adverse Effect
  on Verio or unless such inaccuracies are as a result of actions expressly
  permitted by the provisions of the Merger Agreement;

    (f) Verio shall have failed to perform any obligation or to comply with
  any agreement or covenant of Verio to be performed or complied with by it
  under the Merger Agreement (other than any failures which would not have,
  either individually or in the aggregate, a Material Adverse Effect on
  Verio), which failure to perform or comply, if capable of being cured,
  continues for more than 20 business days after the giving of written notice
  to Verio;

    (g) any person or "group" (as defined in Section 13(d)(3) of the Exchange
  Act), other than NTT Communications, Purchaser or their affiliates or any
  group of which any of them is a member, shall have acquired or announced
  its intention to acquire beneficial ownership (as determined pursuant to
  Rule 13d-3 promulgated under the Exchange Act) of 30% or more of the shares
  of Common Stock;

    (h) there shall have occurred and be continuing (i) any general
  suspension of trading in, or limitation on prices for, securities on Nasdaq
  or any national securities exchange in the United States (excluding any
  coordinated trading halt triggered solely as a result of a specified
  decrease in a market index), (ii) a declaration of a banking moratorium or
  any suspension of payments in respect of banks in the United States or
  Japan or (iii) any limitation (whether or not mandatory) by any
  Governmental Entity on, or other event that materially adversely affects,
  the extension of credit by banks or other lending institutions, or (iv) a
  commencement of a war or armed hostilities or other national or
  international calamity directly or indirectly involving the United States
  or Japan which in any case is reasonably expected to have a Material
  Adverse Effect on Verio or to materially adversely affect NTT
  Communications' or Purchaser's ability to complete the Offer and/or the
  Merger or materially delay the consummation of the Offer and/or the Merger;
  or

    (i) the Merger Agreement shall have been terminated in accordance with
  its terms.

  "Material Adverse Change" or "Material Adverse Effect" means any change or
effect that is or could reasonably be expected (as far as can be foreseen at
the time) to be materially adverse to the business, operations, properties or
results of operations or the condition (financial or otherwise), with all such
matters being considered in the aggregate, of Verio and its subsidiaries,
taken as a whole; provided, that none of the following shall be deemed, either
alone or in combination, to have or constitute a Material Adverse Effect on or
a Material Adverse Change with respect to Verio: (i) changes in the market
price or trading volume of Verio's securities, (ii) conditions generally
affecting the internet service provider or web hosting industries, (iii)
general economic

                                       4
<PAGE>

and business conditions, and (iv) any disruption of employee, customer,
supplier or other similar relationships, or other events or circumstances
arising out of or resulting from actions contemplated by Verio, NTT
Communications and Purchaser in connection with, or which are attributable to,
the execution and announcement of the Merger Agreement or the identity of NTT
Communications.

  The foregoing conditions are for the sole benefit of NTT Communications and
Purchaser and may, subject to the terms of the Merger Agreement, be waived by
NTT Communications and Purchaser in whole or in part at any time and from time
to time in their sole discretion. The failure by NTT Communications or
Purchaser at any time to exercise any of the foregoing rights shall not be
deemed a waiver of any such right, the waiver of any such right with respect
to particular facts and circumstances shall not be deemed a waiver with
respect to any other facts and circumstances and each such right shall be
deemed an ongoing right that may be asserted at any time and from time to
time.

  The Merger. The Merger Agreement provides that Purchaser will be merged with
and into Verio following the satisfaction or waiver of the conditions to the
Merger contained in the Merger Agreement. As a result of the Merger, the
separate corporate existence of Purchaser will cease and Verio will continue
as the Surviving Corporation.

  At the effective time of the Merger (the "Effective Time"), the Certificate
of Incorporation and Bylaws of Verio shall be the Certificate of Incorporation
and Bylaws of the Surviving Corporation and the directors of Purchaser shall
become the directors of the Surviving Corporation and the officers of Verio
shall become the officers of the Surviving Corporation.

  Verio has agreed in the Merger Agreement that it will, as soon as
practicable following the purchase of Shares pursuant to the Offer, (a)
prepare and file with the SEC a proxy statement relating to the Merger
Agreement and use its reasonable best efforts to have it cleared by the SEC
and to cause the proxy statement to be mailed to its stockholders and (b)
convene a special meeting of its stockholders for the purpose of considering
the adoption of the Merger Agreement. The Merger Agreement also provides that,
notwithstanding the foregoing, if NTT Communications or one or more
subsidiaries of NTT Communications shall own at least 90% of the outstanding
shares of Common Stock, NTT Communications and Purchaser shall take all
necessary and appropriate action to cause the Merger to become effective as
soon as practicable after expiration of the Offer without a meeting of the
stockholders of Verio, in accordance with Section 253 of the Delaware General
Corporation Law (the "DGCL").

  Conversion of Securities. As of the Effective Time, by virtue of the Merger
and without any action on the part of Purchaser, Verio or the holders of any
securities of Purchaser or Verio, (a) each share of Common Stock (other than
shares of Common Stock owned by Verio, any wholly owned subsidiary of Verio,
NTT Communications or any wholly owned subsidiary of NTT Communications and
other than shares of Common Stock owned by stockholders, if any, who are
entitled to and who properly exercise dissenter's rights under the DGCL) shall
be converted into the right to receive from the Surviving Corporation, in
cash, without interest, the Merger Consideration and (b) each share of
Preferred Stock (other than shares of Preferred Stock owned by Verio, any
wholly owned subsidiary of Verio, NTT Communications or any wholly owned
subsidiary of NTT Communications and other than shares of Preferred Stock
owned by stockholders, if any, who are entitled to and who properly exercise
dissenter's rights under the DGCL) shall be converted into the right to
receive from the Surviving Corporation, in cash, without interest, the
Preferred Merger Consideration. Each share of stock of Purchaser issued and
outstanding immediately prior to the Effective Time shall, at the Effective
Time, by virtue of the Merger and without any action on the part of the holder
of any shares of stock of Purchaser, be converted into and become one fully
paid and nonassessable share of common stock, $.01 par value, of the Surviving
Corporation.

  The Merger Agreement provides that NTT Communications or the designated
paying agent will be entitled to deduct and withhold from the consideration
otherwise payable pursuant to the Merger Agreement to any holder of Shares
such amounts as NTT Communications or such paying agent is required to deduct
and withhold with respect to the making of such payment under the Internal
Revenue Code or the rules and regulations promulgated thereunder or any
provision of state, local or foreign tax law.

  No Solicitation. Verio shall not, and shall not authorize any of its
subsidiaries to, and shall not authorize any officer, director or employee of
or any financial advisor, attorney or other advisor or representative of Verio
or any of its subsidiaries to, and Verio shall instruct its officers,
directors, financial advisors and attorneys not to (i) solicit, initiate or
encourage the submission of, any Takeover Proposal (as defined below), (ii)
enter into any agreement with respect to or approve or recommend any Takeover
Proposal or (iii) participate in any discussions or negotiations regarding, or
furnish to any person any information with respect to Verio or any subsidiary
of Verio in connection with, or take any other action to facilitate any
inquiries or the making of any proposal that constitutes, or may reasonably be
expected to lead to, any Takeover Proposal; provided, however, that Verio and
its directors shall not be prohibited from furnishing information to, or
entering into or participating in discussions or negotiations with, any person
who makes an unsolicited bona fide written Takeover Proposal if, and only to
the extent that (i) Purchaser has not accepted Shares for payment pursuant to
the Offer, (ii) the Verio Board, after consultation with its independent legal
counsel, determines in good faith that taking such action is necessary

                                       8
<PAGE>

for the Verio Board to comply with its fiduciary duties to Verio's
stockholders under applicable law, (iii) the Verio Board after consultation
with Verio's financial advisors determines in good faith that such Takeover
Proposal, taking into account all legal, financial and regulatory aspects of
such proposal and the person making such proposal, could lead to a Superior
Proposal (as defined below), and (iv) prior to taking such action, Verio
provides the notice to NTT Communications required by the Merger Agreement and
receives from the person making such Takeover Proposal an executed
confidentiality agreement in reasonably customary form and containing terms,
taken as a whole, at least as stringent as the confidentiality agreement
entered into between Verio and NTT Communications. Verio has agreed to, and
has agreed to instruct its financial advisors, attorneys or other
representatives to, immediately (as of the date of the Merger Agreement) cease
any discussions or negotiations, if any, existing at the date of the Merger
Agreement with any persons conducted before the execution of the Merger
Agreement with respect to any Takeover Proposal.

  For purposes of the Merger Agreement, "Takeover Proposal" means any proposal
for (i) a merger or other business combination involving Verio or any of its
subsidiaries, (ii) any proposal or offer to acquire in any manner, directly or
indirectly, an equity interest in or any voting securities of Verio
representing 15% or more of the shares of Common Stock or of the total voting
securities of Verio outstanding or (iii) an offer to acquire in any manner,
directly or indirectly, a substantial portion of the assets of Verio or any of
its subsidiaries, other than the transactions contemplated by the Merger
Agreement. "Superior Proposal" means a bona fide Takeover Proposal made by a
third party on terms which the Verio Board determines in its good faith
judgment to be more favorable to Verio's stockholders than the transactions
contemplated by the Merger Agreement (after receipt of the advice from Verio's
independent financial advisor) and for which financing, to the extent
required, is then committed or which, in the reasonable good faith judgment of
the Verio Board (after receipt of the advice of Verio's independent financial
advisor), is reasonably capable of being obtained by such third party;
provided that for purposes of such definition, clause (ii) of the definition
of "Takeover Proposal" above shall be deemed to read "(ii) any proposal or
offer to acquire in any manner, directly or indirectly, an equity interest in
or any voting securities of Verio representing 50% or more of the shares of
Common Stock or of the total voting securities of Verio outstanding."

  The Merger Agreement provides further that Verio shall advise NTT
Communications in writing of (i) any Takeover Proposal or any inquiry with
respect to or which could reasonably be expected to lead to any Takeover
Proposal received by any officer or director of Verio or, to the knowledge of
Verio, any financial advisor, attorney or other advisor or representative of
Verio, (ii) the material terms of such Takeover Proposal (including a copy of
any written proposal), and (iii) the identity of the person making any such
Takeover Proposal or inquiry. Verio shall use reasonable best efforts to so
advise NTT Communications no later than 24 hours following receipt of such
Takeover Proposal or inquiry and shall advise NTT Communications no later than
48 hours following receipt of such Takeover Proposal or inquiry. If Verio
intends to furnish any person with any information with respect to any
Takeover Proposal, Verio is required to advise NTT Communications in writing
of such intention not less than 24 hours in advance of providing such
information. Verio is further required to keep NTT Communications fully
informed of the status and material terms of any such Takeover Proposal or
inquiry.

  The Merger Agreement provides that nothing contained therein shall prohibit
Verio or the Verio Board from taking a position and disclosing to Verio's
stockholders a position contemplated by the Exchange Act, referring a third
party to the section of the Merger Agreement relating to no solicitation of
Takeover Proposals or from making such disclosure to Verio's stockholders as,
in the good faith judgment of the Verio Board after consultation with Verio's
independent legal counsel, is required under applicable law.

  Third Party Standstill Agreements. During the period from the date of the
Merger Agreement through the Effective Time, Verio has agreed (except, in each
case, to the extent that the Verio Board, after consultation with its
independent legal counsel, determines in good faith that such action or
inaction would be inconsistent with its fiduciary duties to Verio's
stockholders under applicable law) not to terminate, amend, modify or waive
any provision of any confidentiality or standstill agreement to which Verio or
any of its subsidiaries is a party (other than any confidentiality or
standstill agreement involving NTT Communications and any other
confidentiality agreement that is not related to, or does not arise from, a
Takeover Proposal) and to enforce, to the fullest extent permitted under
applicable law, the provisions of any such agreements, including obtaining
injunctions to prevent any breaches of such agreements and to enforce
specifically the terms and provisions thereof in any court of the United
States or any state thereof having jurisdiction.

                                       9

  Stock Based Compensation and Warrants. In the Merger Agreement, Verio has
agreed that, prior to the consummation of the Offer, the Verio Board (or, if
appropriate, a committee thereof) shall adopt such resolutions and take any
and all other action necessary or appropriate to cause each option (a "Stock
Option") to purchase shares of Common Stock issued under Verio's 1996 Stock
Option Plan, 1997 California Stock Option Plan, 1998 Stock Incentive Plan and
1998 Non-Employee Director Stock Incentive Plan (collectively, the "Verio
Stock Option Plans") that is outstanding as of the consummation of the Offer
to be canceled as of the consummation of the Offer, in consideration for which
the holder thereof (an "Option Holder") shall receive the right to receive
from Verio cash in an amount (the "Option Consideration") equal to (A) the
product of (1) the number of shares of Common Stock subject to such option and
(2) the excess, if any, of the Offer Price over the exercise price per share
for the purchase of Common Stock subject to such Stock Option, minus (B) all
applicable federal, state and local taxes required to be withheld in respect
of such payment, subject to the requirements set forth below. In the case of a
Stock Option or portion thereof that is exercisable at, on account of or
before consummation of the Offer, the Option Consideration shall be paid as
soon as reasonably practicable following the acceptance for payment of shares
by Purchaser pursuant to the Offer and the surrender of such Stock Option or
portion thereof to Verio. In the case of a Stock Option or portion thereof
that is not exercisable at the time the Offer is consummated, the Option
Consideration shall be paid to such Option Holder after (A) the end of the
calendar month which includes the date on which such option or portion thereof
would have become exercisable pursuant to the terms of the applicable Stock
Option agreement had such option or portion thereof not been canceled and been
assumed by a successor and (B) the surrender of such Stock Option or portion
thereof with respect to such option to Verio; and in the case of any such
Stock Option that by its terms could not under any circumstances, if it were
assumed, be exercised or become exercisable after consummation of the Offer,
excluding any such option that pursuant to its terms becomes fully exercisable
if not assumed or replaced prior to the consummation of the Offer, if the
employment of an Option Holder is terminated by Verio (or any of its related
entities) within 12 months after the Offer is consummated for any reason,
other than Cause (as defined below) as determined by Verio, the next
installment of Option Consideration with respect to such Option shall be
payable. An Option Holder's rights to Option Consideration under the
immediately preceding sentence shall be evidenced by an agreement in such form
as the Verio Board (or if appropriate, a committee thereof) shall approve with
terms substantially similar to those of the Stock Option to which the such
right to Option Consideration relates and are not inconsistent with the terms
hereof. "Cause" means the Option Holder (1) acts in bad faith and to the
detriment of Verio; (2) refuses or fails to act in accordance with any
specific direction or order of Verio; (3) exhibits in regard to his employment
unfitness or unavailability for service, unsatisfactory performance,
misconduct or incompetence, but not on account of disability; (4) exhibits
dishonesty or habitual neglect or (5) is convicted of a crime involving
dishonesty, breach of trust or physical or emotional harm to any person.

  Pursuant to the Merger Agreement, Verio has agreed to take all actions
necessary to ensure that the Purchase Period (as defined in Verio's 1998
Employee Stock Purchase Plan) applicable to the options outstanding under
Verio's 1998 Employee Stock Purchase Plan is shortened so as to have an
Exercise Date (as defined in the 1998 Employee Stock Purchase Plan) that
occurs before the acceptance for payment by the Purchaser of Shares pursuant
to the Offer; and no current holder of an option to purchase Shares under the
1998 Employee Stock Purchase Plan is permitted to increase his or her rate of
payroll deduction under the plan from and after the date of the Merger
Agreement, except for any such increases a participant is entitled to elect in
accordance with the terms of the plan as in effect on the date of the Merger
Agreement.

  Verio has also agreed to take all actions necessary to provide that,
effective as of acceptance for payment by Purchaser of Shares pursuant to the
Offer, the Verio Stock Option Plans, the 1998 Employee Stock Purchase Plan and
any similar plan or agreement of Verio will be terminated, any rights under
any other plan, program, agreement or arrangement relating to the issuance or
grant of any other interest in respect of the capital stock of Verio or any of
its subsidiaries will be terminated, and no holder of an option to purchase
Shares will have any right to receive any shares of capital stock of Verio or,
if applicable, the Surviving Corporation, upon exercise of any Stock Option or
option outstanding under Verio's 1998 Employee Stock Purchase Plan.

  Verio has agreed that prior to the acceptance for payment of any Shares
pursuant to the Offer, Verio will use reasonable best efforts to obtain the
written confirmation, in form and substance reasonably satisfactory to NTT
Communications, from the holders of the Verio Warrants that after the
Effective Time such warrants will

                                      10
<PAGE>

represent the right to receive an amount equal to (A) the product of (i) the
number of shares of Common Stock subject to such warrant and (ii) the excess,
if any, of the Offer Price over the exercise price per share of Common Stock
subject to such warrant, minus (B) all applicable federal, state and local
taxes required to be withheld in respect of such payment.

  Indemnification. Pursuant to the Merger Agreement, from and after the
Effective Time, NTT Communications will cause the Surviving Corporation to
indemnify, defend and hold harmless (and make advances as incurred to) all
past and present officers and directors of Verio and of its subsidiaries to
the same extent and in the same manner such persons are entitled to
indemnification and advancement of expenses as of the date of the Merger
Agreement by Verio pursuant to the DGCL, Verio's Certificate of Incorporation
or Verio's Bylaws for acts or omissions occurring at or prior to the Effective
Time.

  From and after the Effective Time, NTT Communications shall cause the
Surviving Corporation to perform, as of the consummation of the Offer, all of
the obligations set forth in Verio's Certificate of Incorporation or Bylaws
relating to indemnification and in the indemnification agreements identified
by Verio to NTT Communications on the date of the Merger Agreement. In
addition, NTT Communications shall cause the Surviving Corporation to pay all
amounts that become due and payable under Verio's Certificate of
Incorporation, Bylaws and such indemnification agreements.

  NTT Communications has also agreed to cause the Surviving Corporation to
provide, for a period of not less than six years from the Effective Time, to
or for the persons covered at the date of the Merger Agreement or at the
Effective Time by Verio's director's and officers' insurance and
indemnification policy, insurance that is substantially similar to Verio's
existing policy or, if substantially equivalent insurance coverage is
unavailable, the best available coverage; provided, however, that the
Surviving Corporation will not be required to pay an annual premium for the
director's and officer's insurance in excess of 200% of the last annual
premium paid prior to the date of the Merger Agreement but in such case will
purchase as much coverage as possible for such amount.

  Retention and Incentive Plan; Benefits. Pursuant to the Merger Agreement,
prior to the first scheduled expiration of the Offer, NTT Communications and
Verio shall discuss and explore mutually agreeable retention and incentive
plans with respect to the employees and officers of Verio and its
subsidiaries, to be adopted prior to the consummation of the Offer and
effective immediately after consummation of the Merger.

  In the Merger Agreement, NTT Communications has agreed to cause Purchaser
and the Surviving Corporation and their subsidiaries to honor all enforceable
employment, change in control, deferred compensation, pension, retirement and
severance agreements, pay and personnel policies in effect on the date of the
Merger Agreement and as amended on the date of the Merger Agreement between
Verio or one of its subsidiaries and any employee of Verio or any of its
subsidiaries, or maintained for the benefit of any employee of Verio or any of
its subsidiaries, and honor all annual bonus awards made by Verio or any of
its subsidiaries prior to the date of the Merger Agreement, subject to the
power of Verio or its subsidiaries to amend, modify, invoke or terminate any
such policies and awards pursuant to their terms or applicable law.

  In the Merger Agreement, NTT Communications has agreed, for one year after
the Effective Time, to cause Purchaser and the Surviving Corporation to
provide employees of Verio and its subsidiaries with benefits (including
welfare benefits) that are no less favorable, taken as a whole, than the
benefits provided under Verio's and such subsidiary's benefits plans (other
than equity-based plans) as in effect on the date of the Merger Agreement. To
the extent that service is relevant for eligibility, vesting or benefit
calculations or allowances (including, entitlements to vacation and sick days)
under any plan or arrangement of Verio or its subsidiaries, NTT Communications
shall ensure that such plan or arrangement shall credit employees for service
on or prior to the Effective Time with Verio or any of its subsidiaries.

  Board Representation. The Merger Agreement provides that promptly after such
time as Purchaser acquires Shares pursuant to the Offer, Purchaser will be
entitled to the fullest extent permitted by law to designate at its option up
to that number of directors (rounded to the nearest whole number) of the Verio
Board, subject to

                                      11
<PAGE>

compliance with Section 14(f) of the Exchange Act, as will make the percentage
of Verio's directors designated by Purchaser equal to the percentage of the
aggregate voting power of the shares of Common Stock held by NTT
Communications or any of its subsidiaries. However, in the event that
Purchaser's designees are elected to the Verio Board, until the Effective
Time, the Verio Board shall have at least three directors who were directors
of Verio on the date of the Merger Agreement (the "Continuing Directors"). If
the number of Continuing Directors shall be reduced below three for any reason
whatsoever, the Continuing Directors shall designate a person or persons to
fill such vacancy or vacancies, each of whom shall be deemed to be a
Continuing Director for purposes of the Merger Agreement or, if no Continuing
Directors then remain, the other directors of Verio shall designate three
persons to fill such vacancies who shall not be officers or affiliates of
Verio or any of its subsidiaries, or officers or affiliates of NTT
Communications or any of its subsidiaries, and such persons shall be deemed to
be Continuing Directors for purposes of the Merger Agreement and, in either
case, Purchaser shall cause such person or persons to be elected to fill such
vacancy or vacancies. Following the election or appointment of Purchaser's
designees to the Verio Board and prior to the Effective Time, any amendment,
or waiver of any term or condition, of the Merger Agreement or Verio's
Certificate of Incorporation or Bylaws, any termination of the Merger
Agreement by Verio, any extension by Verio of the time for the performance of
any of the obligations or other acts of Purchaser or NTT Communications or
waiver or assertion of any of Verio's rights under the Merger Agreement, and
any other consent or action by the Verio Board with respect to the Merger
Agreement, will require the concurrence of a majority of the Continuing
Directors and, except as required by applicable law, no other action by Verio,
including any action by any other director of Verio, shall be required for
purposes of the Merger Agreement. To the fullest extent permitted by law,
Verio will take all actions requested by NTT Communications and reasonably
necessary to effect such election. In connection with the foregoing, Verio
will promptly, at the option of NTT Communications, to the fullest extent
permitted by law, Verio's Certificate of Incorporation and Verio's Bylaws,
either increase the size of the Verio Board and/or obtain the resignation of
such number of its current directors as is necessary to enable Purchaser's
designees to be elected or appointed to the Verio Board as provided above.

  Conditions of the Merger. The respective obligations of each party to effect
the Merger shall be subject to the satisfaction (or waiver by each party)
prior to the Effective Time of the following conditions: (i) the Merger
Agreement shall have been approved and adopted by the affirmative vote of the
stockholders of Verio (unless the vote of stockholders is not required under
the DGCL and Verio's Certificate of Incorporation); (ii) any waiting period
(and any extension thereof) applicable to the consummation of the Merger under
the HSR Act shall have expired or been terminated; (iii) Purchaser shall have
previously accepted for payment and paid for Shares pursuant to the Offer,
except that this condition shall not apply if Purchaser shall have failed to
purchase Shares pursuant to the Offer in breach of its obligations under the
Merger Agreement; and (iv) no court or other Governmental Entity (as defined
in the Merger Agreement) having jurisdiction over Verio or NTT Communications
or any of their respective subsidiaries shall have enacted, issued,
promulgated, enforced or entered any law, rule, regulation, executive order,
decree, injunction or other order (whether temporary, preliminary or
permanent) which is then in effect and has the effect of making the Merger
illegal.

  Termination. The Merger Agreement provides that it may be terminated at any
time prior to the Effective Time, whether before or after adoption of the
Merger Agreement by the stockholders of Verio:

    (a) by mutual written consent of NTT Communications and Verio;

    (b) by either NTT Communications or Verio: (i) if (x) as a result of the
  failure of any of the conditions to the Offer as set forth in Section 13 of
  this Offer to Purchase, the Offer shall have terminated or expired in
  accordance with its terms without Purchaser having accepted for payment any
  Shares pursuant to the Offer or (y) Purchaser shall not have accepted for
  payment any Shares pursuant to the Offer prior to (A) September 8, 2000, if
  the condition to the Offer relating to the Exon-Florio Amendment has been
  satisfied or waived prior to such date or (B) November 10, 2000 if the
  condition to the Offer relating to the Exon-Florio Amendment shall not have
  been satisfied or waived on or prior to September 8, 2000 (provided, that
  the right to terminate the Merger Agreement pursuant to this clause (b)(i)
  shall not be available to any party whose failure to perform any of its
  obligations under the Merger Agreement results in the failure of

                                      12
<PAGE>

  any such condition to the Offer or if the failure of such condition results
  from facts or circumstances that constitute a breach of any representation
  or warranty under the Merger Agreement by such party) or (ii) if any
  Governmental Entity shall have issued an order, decree or ruling or taken
  any other action permanently enjoining, restraining or otherwise
  prohibiting the acceptance for payment of, or payment for, Shares pursuant
  to the Offer and such order, decree or ruling or other action shall have
  become final and nonappealable;

    (c) by NTT Communications or Purchaser prior to the purchase of Shares
  pursuant to the Offer in the event of a breach by Verio of any
  representation, warranty, covenant or other agreement contained in the
  Merger Agreement which (i) would give rise to the failure of the Offer
  conditions described in paragraph (e) or (f) of Section 13 and (ii) cannot
  be or has not been cured within 30 days after the giving of written notice
  to Verio;

    (d) by NTT Communications or Purchaser if either NTT Communications or
  Purchaser is entitled to terminate the Offer as a result of the occurrence
  of any event set forth in paragraph (d) of Section 13;

    (e) by Verio if the Verio Board determines that a Takeover Proposal
  constitutes a Superior Proposal and the Verio Board determines in its good
  faith judgment, after consultation with independent counsel, that failing
  to terminate the Merger Agreement would be inconsistent with its fiduciary
  duties under applicable law; provided, that it has complied in all material
  respects with the notice and other provisions of the Merger Agreement
  relating to no solicitation of Takeover Proposals and it complies to the
  extent applicable with requirements of the Merger Agreement relating to
  payment of Expenses and the Termination Fee (each as defined below under
  "--Fees and Expenses"); and provided further that Verio may not terminate
  the Merger Agreement pursuant to this clause (e) unless and until 72 hours
  have elapsed following the delivery to NTT Communications of a written
  notice of such determination by the Verio Board (such notice may be given
  by Verio contingent on termination of the Merger Agreement becoming
  effective immediately prior to Verio entering into a definitive agreement
  with respect to a Superior Proposal);

    (f) by Verio, if (i) any of the representations or warranties of NTT
  Communications or Purchaser set forth in the Merger Agreement that are
  qualified as to materiality shall not be true and correct in any respect or
  any such representations or warranties that are not so qualified shall not
  be true and correct in any material respect or (ii) NTT Communications or
  Purchaser shall have failed to perform in any material respect any material
  obligation or to comply in any material respect with any material agreement
  or covenant of NTT Communications or Purchaser to be performed or complied
  with by it under the Merger Agreement and such untruth, incorrectness or
  failure cannot be or has not been cured within 30 days after the giving of
  written notice to NTT Communications or Purchaser, as applicable; or

    (g) by Verio, if the Offer has not been timely commenced.

  In the event of a termination of the Merger Agreement by either Verio or NTT
Communications, the Merger Agreement shall become void and there shall be no
liability or obligation on the part of NTT Communications, Purchaser or Verio
or their respective officers or directors, other than for certain provisions
of the Merger Agreement pertaining to the payment of certain expenses and fees
and except for certain confidentiality obligations of the parties and other
than for liability for any breach of a representation or warranty contained in
the Merger Agreement, the breach of any covenant contained in the Merger
Agreement or for fraud.

  Fees and Expenses. Except as provided in the Merger Agreement, whether or
not the Merger is consummated, all costs and expenses incurred in connection
with the Merger Agreement and the transactions contemplated thereby shall be
paid by the party incurring such costs and expenses.

  The Merger Agreement provides that Verio will pay, or cause to be paid, in
same day funds to NTT Communications the following amounts under the
circumstances and at the times set forth as follows:

    (i) if NTT Communications or Purchaser terminates the Merger Agreement in

  and the Expenses of NTT Communications upon demand; or

    (iii) if NTT Communications or Purchaser terminates the Merger Agreement
  in accordance with the provision described in clause (c) under "--
  Termination" above as a result of the breach by Verio of any covenant or
  agreement contained in the Merger Agreement resulting in a failure of the
  conditions to the Offer set forth in paragraph (f) of Section 13 and at the
  time of any such termination a Takeover Proposal shall have been made
  (other than a Takeover Proposal made prior to the date of the Merger
  Agreement), (x) Verio shall pay the Expenses of NTT Communications upon
  demand, and (y) if concurrently therewith or within 12 months thereafter,
  (A) Verio enters into a merger agreement, acquisition agreement or similar
  agreement (including a letter of intent) with respect to a Takeover
  Proposal, or a Takeover Proposal is consummated, involving any party (1)
  with whom Verio had any discussions with respect to a Takeover Proposal,
  (2) to whom Verio furnished information with respect to or with a view to a
  Takeover Proposal or (3) who had submitted a proposal or expressed any
  interest publicly in a Takeover Proposal, in the case of each of clauses
  (1), (2) and (3), prior to such termination, or (B) Verio enters into a
  merger agreement, acquisition agreement or similar agreement (including a
  letter of intent) with respect to a Superior Proposal, or a Superior
  Proposal is consummated, then, in the case of either (A) or (B) above,
  Verio shall pay the Termination Fee upon the earlier of the execution of
  such agreement or upon consummation of such Takeover Proposal or Superior
  Proposal.

  The Merger Agreement also provides that if NTT Communications or Verio
terminates the Merger Agreement pursuant to the provision described in clause
(b)(i)(y) under "--Termination" above and at the time of such termination all
conditions to the Offer except the condition relating to the Exon-Florio
Amendment have been satisfied or waived, then NTT Communications shall pay, or
cause to be paid, to Verio, in same day funds, an amount equal to the Expenses
of Verio upon demand.

  For purposes of the Merger Agreement, "Expenses" means documented out-of-
pocket fees and expenses, up to a maximum of $5,000,000, incurred or paid by
or on behalf of NTT Communications or Verio, as the case may be, in connection
with the Offer, the Merger or the consummation of any of the transactions
contemplated by the Merger Agreement, including all fees and expenses of law
firms, commercial banks, investment banking firms, accountants, experts and
consultants.

  Senior Notes. If NTT Communications shall request, Verio shall either (i)
solicit consents of the holders of one or more of the series of its Senior
Notes to such amendments of the related indentures as NTT Communications shall
determine or (ii) make a tender offer to purchase any or all of the series of
the Senior Notes (which tender offer may also include solicitation of consents
to the amendment of the related indentures) at such price or prices and such
terms as shall be determined by NTT Communications. NTT Communications and
Verio shall cooperate in the preparation of any documentation to be sent to
the holders of Senior Notes in connection with any such consent solicitation
or tender offer. It shall be a condition to the obligation of Verio to
complete any such consent solicitation or tender offer that Purchaser purchase
Shares pursuant to the Offer. The successful completion of any such consent
solicitation or tender offer is not a condition to the Offer.

  Equity Swap Transaction. In the Merger Agreement, NTT Communications has
agreed to cause a loan to be made to Verio, LLC, a wholly owned subsidiary of
Verio, promptly following the purchase of Shares pursuant to the Offer in an
amount in cash not to exceed $40 million so as to permit Verio, LLC to effect
a settlement or termination of that certain Confirmation for Equity Swap
Transaction Between Salomon Brothers Holding Company Inc., Verio, LLC and
Verio dated as of March 17, 2000. Such loan shall be on such terms as shall be
reasonably acceptable to NTT Communications and Verio.

Confidentiality Agreement.

  Verio and NTT Communications entered into a confidentiality agreement, dated
as of April 7, 2000 (the "Confidentiality Agreement"). The Confidentiality
Agreement provides that NTT Communications will not, and

                                      14
<PAGE>

will cause its directors, employees, members, financial advisers, lenders,
accountants, attorneys, agents and other persons or entities controlled by NTT

  Additionally, NTT Communications agreed for a period of two years from the
date of the Confidentiality Agreement to be bound by its obligations of
confidentiality and other obligations under the Confidentiality Agreement,
even if the parties decide not to proceed with a transaction.

  The summary set forth herein does not purport to be complete and is
qualified in its entirety by reference to the complete text of the
Confidentiality Agreement, a copy of which is filed as Exhibit (e)(2), hereto
and is incorporated by reference in its entirety.

Item 4. The Solicitation or Recommendation.

  (a) Recommendation.

  At a meeting held on May 7, 2000, the Verio Board (1) determined that the
Offer and the Merger were fair to, and in the best interests of, holders of
Preferred Stock and holders of Common Stock, (2) approved the Merger Agreement
and the transactions contemplated by the Merger Agreement, including the Offer
and the Merger, and (3) recommended that Verio's stockholders accept the Offer
and tender their Shares thereunder and adopt the Merger Agreement.

  A press release announcing the commencement of the Offer and a letter to the
stockholders communicating the Verio Board's recommendation are filed herewith
as Exhibits (a)(1)(I) and (a)(2), respectively, and are incorporated by
reference herein in their entirety.

  (b) Reasons.

  Background of the Offer.

  On May 15, 1998, a U.S. subsidiary of NTT purchased 8,987,754 shares of
Common Stock pursuant to a stock purchase agreement between NTT and Verio. At
the time of the purchase of shares of Common Stock, NTT and Verio entered into
an Investment Agreement, dated as of April 7, 1998 (the "Investment
Agreement") which contains certain restrictions on the shares of Common Stock
purchased by the NTT subsidiary, and which grants NTT the right to name one
member of the Verio Board. See "Certain Relationships and Related
Transactions--Other Transactions" in the Information Statement.


                                      15

  In April of 1999, Verio's management met with representatives of Salomon
Smith Barney Inc. ("Salomon Smith Barney") to discuss various possible
alternatives available to Verio to leverage its assets, customer base and
distribution channels, and generally to increase its stock performance. Verio
formally engaged Salomon Smith Barney, as of April 21, 1999, as its financial
advisor for the purpose of assisting Verio in identifying logical candidates
for strategic relationships that would further these efforts.

  Over most of the remainder of 1999, Verio and its financial advisors met
with several companies to discuss possible strategic relationships that would
allow the two companies to leverage their respective capabilities. In several
instances, these discussions led to conversations about the possible merger of
the two companies' operations. In some cases, Verio and the other company
began to conduct preliminary due diligence investigations of each other.
However, none of these discussions proceeded past a preliminary due diligence
stage, and no firm proposals were presented.

  On November 29, 1999, Justin Jaschke, the chief executive officer of Verio,
and Sean Brophy, the vice president of corporate development of Verio, based
on an introduction by an investment bank, met by videoconference with the
chief executive officer and the chief financial officer of a company in the
telecommunications industry (the "Interested Party") to discuss generally
areas of mutual interest and potential cooperation. At the end of the
videoconference, the parties agreed to attempt to have a subsequent, in-person
meeting and to have larger group meetings.

   At a meeting on December 16, 1999, in connection with its analysis of the
budget presented by management for 2000, and various alternative strategic
initiatives that might be undertaken by Verio, the Verio Board directed
management to explore strategic alternatives with respect to the Internet
access portion of its business, including the possibility of separating the
Internet access portion from the web-hosting and enhanced services aspects of
its business. During late 1999 and early 2000, Verio, along with Salomon Smith
Barney, began to consider potential alternatives and whether shareholder value
would be enhanced by disposing of the internet access portion of Verio's
business in order to focus its efforts more exclusively on the web-hosting and
enhanced services aspects of Verio's business. NTT Communications, through its
designee on the Verio Board, was aware of Verio's deliberations and
discussions concerning this possibility. NTT Communications informed Verio
that, if Verio decided to sell its internet access business, NTT
Communications might be interested in making a proposal to acquire that
business.

   On January 12, 2000, Mr. Jaschke met with the senior management of another
telecommunications company during an industry conference sponsored by Salomon
Smith Barney. The parties discussed their respective business plans and
strategies and the potential synergies that could result from a combination of
their businesses. At the end of the meeting, Mr. Jaschke and this other
company's management agreed to have further in-person meetings. Senior
management teams from Verio and this other company then met on January 25,
2000 and continued the discussion of their respective businesses and potential
synergies. The meetings were completed without any determination being made as
to what further steps, if any, should be taken, and neither company thereafter
indicated any significant interest in pursuing a potential combination, and no
other significant discussions on that topic took place between Verio and the
other company.

   On February 10, 2000, Mr. Jaschke, Mr. Brophy, Peter Fritzinger, the chief
financial officer of Verio, and other Verio representatives met with
representatives of NTT Communications to discuss NTT Communications' potential
interest if Verio were to decide to sell its Internet business. They discussed
the feasibility of such a sale to NTT Communications, as well as a potential
timeline for separating these assets from the web hosting and other enhanced
services aspects of Verio's business.

   On February 25, 2000, Mr. Jaschke, Mr. Brophy and Mr. Fritzinger met with
the chief executive officer and chief financial officer of the Interested
Party. The Interested Party reported that they had undertaken an evaluation of
the operations of the two companies and the relative benefits that could be
derived from various possible strategic and operational relationships, and had
concluded that the synergies could best be leveraged though a combination of
the two companies. Following this discussion, both parties agreed to have a
follow-up meeting at the Interested Party's facilities to provide additional
background on their respective companies.

   On March 7, 2000, members of Verio's senior management met at the
Interested Party's headquarters with members of the Interested Party's
management team to discuss Verio's and the Interested Party's respective

                                      16
<PAGE>

business and operations. At the end of the meeting, they agreed to have a
follow-up due diligence session at Verio's headquarters. On March 23 and 24,
2000 the Interested Party's senior management and a team of its legal and
financial advisors performed a due diligence review of Verio at Verio's
headquarters.

   On March 8 and 9, 2000, NTT Communications' representatives met with
Christopher DeMarche, the chief technical officer of Verio, and James
Treuting, the president of Verio's internet access operations, for the purpose
of better understanding Verio's internet access business. The next day, Mr.
Jaschke, Mr. Fritzinger and Carla Donelson, the general counsel and corporate
secretary of Verio, met by teleconference with representatives of NTT
Communications. They informed NTT Communications that they believed the
separation of Verio's two businesses would require substantial effort and at
least four to six months to complete, in light of the significantly integrated
nature of the operation of Verio's Internet access, web-hosting and enhanced
services businesses. They also noted that the Verio Board and management had
not determined that such a sale was appropriate or desirable, and that they
had not yet determined the process for conducting any sale that they might
consider. The parties agreed to meet again at some later time to further
discuss this.

  On March 30, 2000, Mr. Jaschke received a letter from the Interested Party,
which included a summary of terms for a possible combination of the two
companies. These terms contemplated a stock-for-stock merger in which the
Interested Party would acquire Verio and Verio's stockholders would receive
stock in the Interested Party. The term sheet also contemplated that the two
largest stockholders of Verio (which would include NTT Communications) would
sign agreements to vote for the merger, and that at the time of execution of
the definitive agreement with respect to the merger the parties also would
enter into mutual operational agreements providing that each would become a
provider to the other of their respective products and services. The
Interested Party's letter indicated that the proposal was subject to the entry
into a mutually satisfactory definitive agreement, as well as to confirmation
by the Interested Party of its assumptions regarding Verio's first quarter
2000 performance.

  Pursuant to the Investment Agreement, Mr. Jaschke informed Yukimasa Ito, a
member of the Verio Board and an officer of NTT Communications, of Verio's
receipt of the Interested Party's proposal. Mr. Ito is the designee of NTT on
the Verio Board pursuant to the Investment Agreement. The Investment Agreement
generally prohibited NTT from making proposals to acquire Verio, subject to
exceptions described in that agreement. However, if Verio, among other things,
elected to enter into negotiations regarding a merger or other business
combination, then NTT and its affiliates were to be released from these
restrictions so that they could participate in the process for negotiating a
potential merger or combination in a manner substantially comparable to that
made available to the other participants in the process. Mr. Ito called Mr.
Jaschke later that day to say that NTT Communications might be interested in
making a proposal with respect to Verio.

  At a meeting of the Verio Board on April 1, 2000, Mr. Jaschke reviewed with
the Verio Board the contents of the Interested Party's summary of terms. At
the meeting, Salomon Smith Barney reviewed the proposed terms and discussed
the preliminary relative valuations of Verio and the Interested Party. At the
same meeting, Verio's legal counsel discussed with the Verio Board the
fiduciary duties of the members of the Verio Board. The Verio Board members
then asked Mr. Ito to state whether NTT Communications would respond to the
Interested Party's term sheet. Mr. Ito replied that he was not yet in a
position to formally comment, but that NTT Communications might have an
interest in presenting its own proposal to acquire Verio. Mr. Ito was then
excused from further participation in this meeting as well as all future Verio
Board deliberations relating to possible business combinations involving
Verio, including the discussions of the proposals made by the Interested Party
and NTT Communications. The Verio Board also discussed the impact that the
announcement of certain strategic operational agreements that Verio was then
negotiating might have on the relative valuation of Verio.

  At a meeting of the Verio Board held on April 5, 2000, Mr. Ito was once
again asked to state whether NTT Communications would respond to the
Interested Party's term sheet. Mr. Ito confirmed that NTT Communications
potentially was interested in submitting a proposal to Verio concerning NTT
Communication's acquisition of Verio's business operations. Mr. Ito concluded
by stating that NTT Communications was giving serious consideration to this
matter and expected to indicate its interest in such a transaction, if any, by
Saturday

                                      17
<PAGE>

morning, April 8, 2000. After Mr. Ito was excused from the meeting, the Verio
Board discussed the Interested Party's term sheet and NTT Communications'
potential interest. The Verio Board also discussed the impact that the
announcement of certain strategic operational agreements that Verio was then
negotiating might have on the relative valuation of Verio. The Verio Board
directed Verio's management to continue its due diligence review of the
Interested Party and to continue its negotiations of the Interested Party's
term sheet, including the proposed exchange ratio, pending further indications
of interest from NTT Communications.

  On April 5, 6 and 7, 2000 representatives of Verio's management and its
legal and financial advisors met with representatives of the Interested Party
and its advisors at the Interested Party's facilities to conduct due
diligence. During these meetings the Interested Party delivered to the Verio
representatives a draft definitive agreement.

  At a meeting of the NTT Communications board of directors on April 7, 2000,
the President and Chief Executive Officer of NTT Communications, Masanobu
Suzuki, reviewed with the board the possible acquisition of Verio. The board
authorized Mr. Suzuki to continue to explore the possibility of making a
proposal to acquire Verio by means of a tender offer.

  After the board meeting, Mr. Suzuki sent a letter to Mr. Jaschke expressing
the general conditions under which NTT Communications might be interested in
acquiring Verio. This nonbinding indication of interest contemplated a tender
offer by a subsidiary of NTT Communications for all outstanding shares of
Verio Common Stock for $65 in cash per share, net to the seller, followed by a
merger of NTT Communications' subsidiary with and into Verio. Mr. Ito
indicated that NTT Communications had not yet approved any plan or proposal to
acquire Verio, and that NTT Communications' board of directors had only
authorized its management to explore the possibility of making a proposal on
the terms described in the letter. NTT Communications and Verio also signed a
confidentiality agreement, dated as of April 7, 2000.

  On the basis of the non-binding indication of interest submitted by NTT
Communications, the Verio Board held a meeting on April 7, 2000 with its legal
and financial advisors to discuss NTT Communications' letter and the status of
negotiations with the Interested Party. After discussing the contents of the
letter, the Verio Board concluded that it needed additional information
regarding NTT Communications' interest. The Verio Board directed Mr. Jaschke
to discuss the indication of interest with NTT Communications' senior
management during upcoming meetings with them in Denver scheduled for April
11, 2000.

  The Verio Board met on April 9, 2000, to discuss further the contents of the
NTT Communications' letter. Salomon Smith Barney provided advice to the Verio
Board concerning the financial implications of the proposals submitted by the
Interested Party and NTT Communications, and discussed the preliminary
relative valuations of the Interested Party and Verio. Salomon Smith Barney
also discussed its preliminary valuation of the potential NTT Communications
proposal, and the relative premium involved. Salomon Smith Barney also
discussed the results of its preliminary financial analysis with respect to
the Interested Party. Mr. Fritzinger summarized the results of Verio's on-site
due diligence review of the Interested Party and its business operations
during April 5 through 7, 2000 meetings.

  During the week of April 10, 2000 Verio's management and its legal and
financial advisors continued their due diligence investigation of the
Interested Party. They also negotiated with the Interested Party's management
and legal and financial advisors the terms of the draft merger agreement that
the Interested Party had prepared.

  On April 10, 2000, the chief financial officer of the Interested Party
disclosed to Mr. Jaschke that it wished to extend the discussions concerning
the proposed merger between the parties because of the significant volatility
being experienced on the Nasdaq National Market as well as in U.S. stock
markets generally. Both the Interested Party's management and Verio's
management were concerned with the difficulty in determining an appropriate
relative value for the two companies during a time of such extreme market
volatility. During the next two weeks, Verio and its legal advisors
nevertheless continued to communicate with the Interested Party's legal
advisors concerning the timing of a proposed transaction and to discuss the
terms of the draft merger agreement.


                                      18
<PAGE>

  On April 11, 2000, Mr. Suzuki and other representatives of NTT
Communications' management and its legal and financial advisors met with
Verio's representatives and advisors at Verio's headquarters in Colorado to
discuss NTT Communications' summary of possible terms.

  The Verio Board met on April 11, 2000 to discuss the status of the
respective negotiations with the Interested Party and NTT Communications. Mr.
Jaschke informed the Verio Board that the Interested Party had indicated its
desire to extend the timing for the discussions of the proposed merger
transaction. Mr. Jaschke also noted that he was still waiting for the
Interested Party to respond with a new proposal regarding the exchange ratio
that would apply in a merger between Verio and the Interested Party.

  On April 12, 2000, NTT Communications' legal counsel delivered to Verio a
draft merger agreement. The management and legal and financial advisors of
Verio and NTT Communications proceeded to review and discuss the draft. During
these discussions, the representatives of NTT Communications said that NTT
Communications' offer, if made, would include an offer to purchase outstanding
Verio Preferred Stock at the price to be offered for Verio Common Stock,
adjusted for the ratio at which Verio Preferred Stock was then convertible
into shares of Verio Common Stock, and that shares of Verio Preferred Stock
cancelled in connection with the merger following the closing of the offer
would receive the same consideration.

  The Verio Board met again on April 14, 2000 to discuss the status of the
respective negotiations. The Verio Board discussed the differences between the
two proposals, noting that neither proposal as yet reflected a binding
commitment.

  Late on April 15, 2000, Mr. Suzuki informed Mr. Jaschke that NTT
Communications would have difficulty making a firm proposal at a $65 per share
price, given the stock market's continued volatility and general decline,
particularly the decline in internet and technology stocks, including Verio
Common Stock. Negotiations regarding NTT Communications' draft agreement were
then deferred until NTT Communications could be ready to make such a proposal.

  On the afternoon of April 18, 2000, the Verio Board met to consider the
status of the respective negotiations with the Interested Party and NTT
Communications. Mr. Jaschke informed the Verio Board that he had been told
that NTT Communications did not believe that it could give further
consideration to a possible transaction with Verio during the next seven to
ten days because of continued stock market volatility. Mr. Jaschke also
informed the Verio Board that he had been told that the Interested Party's
board might meet soon to consider whether to continue the negotiations with
Verio.

  The Verio Board met on April 20, 2000 with its advisors to receive updates
from Verio's management and to discuss the status of the respective
negotiations.

  The Interested Party did not make any further proposals to Verio. On April
21, 2000 Mr. Jaschke informed the chief executive officer of the Interested
Party that Verio had received a draft merger agreement from another potential
bidder. The chief executive officer said that the Interested Party might be
interested in accelerating its deliberations on when and whether to proceed
with negotiations if Verio received a firm proposal from another party.

  During a conversation with Mr. Jaschke over the weekend of April 29, 2000,
the chief executive officer of the Interested Party indicated a desire to
further delay discussions regarding the potential transaction until the end of
the following week, in light of continued market volatility. He also advised
Mr. Jaschke that the Interested
Party wanted to delay further negotiations in light of other disclosure issues
that the Interested Party would face were the discussions to proceed in the
near term. The next week Verio's legal counsel, at Verio's direction, asked
the Interested Party's counsel when a revised draft merger agreement would be
available. The Interested Party's counsel replied that a revised draft would
be forthcoming but no draft was delivered.

                                      19
<PAGE>

  The Verio Board met on April 30, 2000 with its advisors to receive updates
from Verio's management and to discuss the status of the respective
negotiations.

  NTT Communications' negotiating team arrived in Denver on May 5, 2000 to
resume negotiations of its proposed merger agreement, while its senior
management in Tokyo continued to deliberate on whether to submit a firm
proposal to Verio with respect to price.

  During the night of May 5-6, 2000, Mr. Jaschke had various telephone calls
with NTT Communications' representatives, including Mr. Suzuki. During such
discussions, NTT Communications' representatives informed Mr. Jaschke that any
proposal that NTT Communications might be willing to make would likely not
include an offer price greater than the "mid-to-upper 50s," due to the
significantly changed market conditions since April 7, 2000 when their
original nonbinding proposal was submitted. Mr. Jaschke indicated to Mr.
Suzuki that he did not believe that the Verio Board would accept a proposal at
such a price. After discussing the matter with NTT Communications' senior
management in Tokyo, the next day Mr. Suzuki notified Mr. Jaschke that NTT
might be able to make a proposal of $60 per share of Verio Common Stock, if a
definitive agreement could be executed on May 6 or 7.

  After internal discussions at NTT Communications, on the morning of May 6,
2000 Mr. Suzuki sent a second letter to Mr. Jaschke, in which NTT
Communications described the revised general conditions under which it was
authorized to explore the making of a proposal to acquire Verio. The letter
indicated that a proposal, if made, would provide for a cash tender offer to
acquire Verio for $60 per share of Verio Common Stock, followed by a merger
for the same consideration.

  Later on May 6, 2000, Mr. Jaschke informed the chief executive officer of
the Interested Party that Verio had received an all cash proposal from another
bidder for $60 per share of Verio Common Stock. In a subsequent conversation
later that day, the chief executive officer of the Interested Party told Mr.
Jaschke that the Interested Party would not be prepared to submit a new
proposal to Verio for at least a few days.

  Mr. Jaschke reported these developments to the Verio Board during a meeting
on May 6, 2000. The Verio Board discussed these developments and the
alternatives available to Verio, and authorized Verio's management to continue
to negotiate the potential transaction with NTT Communications. The Verio
Board then agreed to continue the same meeting of the Board at 8:00 a.m. the
following day. Members of Verio's management team then continued their
negotiations with NTT Communications and its advisors.

  On the evening of May 7, 2000 (Tokyo time), the board of directors of NTT
Communications received the final terms of the draft merger agreement and
approved execution of the definitive merger agreement with Verio. Later in the
evening of May 7, 2000, the board of directors of NTT accepted the decision of
NTT Communications to proceed with the transaction.

  On May 7, 2000, at the continued meeting of the Verio Board, members of
Verio's management reported to the Verio Board on the status of the
negotiations with NTT Communications. The Verio Board reviewed the final terms
of the draft merger agreement. At this meeting, Salomon Smith Barney presented
its financial analysis of the proposed transaction and its oral opinion, later
confirmed in writing as of the same date, that, as of that date, the
consideration to be paid pursuant to the proposed tender offer and merger,
taken together, was fair, from a financial point of view, to the holders of
Verio Common Stock (other than NTT Communications) and Verio Preferred Stock.
After further discussion, the Verio Board approved, by unanimous vote of the
directors present (which included all directors other than Mr. Ito), the
transaction and the entry into the definitive agreements by Verio.

  On the afternoon of May 7, 2000, the Merger Agreement was executed by Verio,
NTT Communications and Purchaser. Immediately after execution of the Merger
Agreement, a press release announcing the transaction was issued by Verio and
NTT Communications.

  Fairness of the Offer and the Merger.

  In reaching the conclusions described in Item 4 (a) above, the Verio Board
identified several potential benefits of the Offer and the Merger to
stockholders, including:

  .  The fact that the Offer Price of $60.00 per share of Common Stock and
     the Preferred Offer Price of $62.136 per share of Preferred Stock to be
     received by Verio's stockholders in both the Offer and the Merger
     represent premiums of 67% and 35.7%, respectively, over the closing
     market prices of the Common Stock and Preferred Stock of $35.9375 and
     $45.799, respectively, on May 5, 2000, the last full trading day prior
     to the date that NTT Communications delivered its proposal to the Verio
     Board, and that the Offer Price represents a premium of 73.1% and 88.5%
     over the average trading price of the Common Stock during the 5 and 20-
     day trading periods prior to the execution of the Merger Agreement.

  .  The fact that the purchase price would be payable in cash, thus
     eliminating any uncertainties in valuing the consideration to be
     received by Verio's stockholders, which were particularly acute in light
     of the recent volatility in the price of the Common Stock, as well as
     volatility in the market prices of shares of other telecommunications
     and Web hosting companies and in the Nasdaq Stock Market in general.

  .  The fact that the Offer and the Merger provide for a prompt cash tender
     offer for all Shares to be followed by a merger for the same
     consideration, thereby enabling Verio's stockholders to obtain cash in
     exchange for their shares at the earliest possible time.

  .  The likelihood that the Offer and the Merger would be consummated,
     including the fact that the Offer and the Merger would not be subject to
     any financing condition and that NTT Communications has represented that
     the funds necessary to consummate the Offer and the Merger will be
     provided and has agreed to cause Purchaser to fully perform all of
     Purchaser's obligations under the Merger Agreement.

  The Verio Board also consulted with Verio's senior management, as well as
its legal counsel, independent accountants and financial advisors, in reaching
its decision to approve the Offer and the Merger. Among the factors considered
by the Verio Board in its deliberations were the following:

  .  The presentations and views expressed by Verio's management regarding,
     among other things, the financial condition, results of operations, cash
     flows, business and prospects of Verio and management's recommendation
     of the Offer and the Merger.

  .  The presentation of Salomon Smith Barney at the meeting of the Verio
     Board held on May 7, 2000 and the opinion of Salomon Smith Barney dated
     May 7, 2000, that, as of such date, the per Share consideration to be
     received by the holders of shares of Common Stock (other than NTT
     Communications and its affiliates) and the per Share consideration to be
     received by the holders of shares of Preferred Stock in the Offer and
     the Merger, taken together, was fair from a financial point of view to
     such stockholders. The full text of Salomon Smith Barney's written
     opinion is attached hereto as Schedule II and is incorporated herein by
     reference. Such opinion should be read in its entirety for a description
     of the procedures followed, assumptions and qualifications made, matters
     considered and limitations of the review undertaken by Salomon Smith
     Barney. Salomon Smith Barney did not express any opinion with respect to
     the Verio Warrants. See "Special Factors--Opinion of Financial Advisor
     of Verio" in the Offer to Purchase.

  .  The volatility in the market price of, and recent trading activity in,
     the Common Stock, as reflected on the Nasdaq National Market, and the
     market prices of other telecommunications and Web hosting companies. In
     particular, the Verio Board noted that the closing prices of the Common
     Stock had fluctuated between $80 and $23.6875 during the three months
     prior to the execution of the Merger Agreement.

  .  Valuations based on premiums paid in comparable acquisition transactions
     and discounted cash flow analysis.

                                      21
<PAGE>

  .  Verio's prospects if it were to remain independent, publicly traded
     entity, including the risks of competing against companies that have far
     greater resources, distribution capacity, product offerings and market
     reach than Verio.

  .  Other potential strategic alternatives, such as a stock-for-stock
     combination or a sale of portions of Verio's backbone infrastructure and
     related operations as separate assets. Salomon Smith Barney had been
     exploring such possible alternatives on behalf of Verio for a period of
     more than one year prior to the execution of the Merger Agreement.

  .  The fact that the Merger Agreement permits Verio, under certain
     circumstances, to enter into or participate in discussions or
     negotiations with any person who makes an unsolicited bona fide written
     offer to acquire Verio that could lead to a Superior Proposal (as
     defined in the Merger Agreement).

  .  Provisions of the Merger Agreement that allow the Verio Board to
     terminate the Merger Agreement if, prior to the closing of the Merger,
     Verio has received a Superior Proposal and the Verio Board determines,
     in its good faith judgement after consultation with independent legal
     counsel, that failing to terminate the Merger Agreement would be
     inconsistent with its fiduciary duties under applicable law.

  .  The fact that the only regulatory qualifications required to consummate
     the Merger were (i) expiration or termination of the waiting period
     under the HSR Act and (ii) expiration of the applicable review process
     under the Exon-Florio Amendment without government action to block or
     prevent the consummation of the Offer or the Merger, and the favorable
     prospects for obtaining all such qualifications. See Item 8.

  .  The limited ability of NTT Communications and Purchaser to terminate the
     Offer or the Merger Agreement, including the absence of a termination
     provision related to volatility of Verio's or NTT's Communications'
     stock prices or of any market indices.

  .  The arm's-length negotiations between representatives of Verio and NTT
     Communications leading to the belief of the Verio Board that $60.00 per
     share of Common Stock and $62.136 per share of Preferred Stock
     represented prices that were fair to and in the best interests of
     Verio's stockholders given the facts and circumstances described above.

  .  Stockholders who believe that the terms of the Offer and the Merger are
     not fair can pursue appraisal rights in the Merger under state law.

  The Verio Board also identified and considered a number of uncertainties and
risks in its deliberations concerning the Offer and the Merger, including the
following:

  .  The possibility that, although the Offer gives Verio's stockholders the
     opportunity to realize a premium over the price at which the Common
     Stock traded immediately prior to the public announcement of the Offer
     and the Merger, the price or value of the Common Stock may increase in
     the future, and Verio's shareholders would not benefit from such future
     increases.

  .  The circumstances under the Merger Agreement under which the $175
     million Termination Fee and expense reimbursement of up to $5 million
     become payable by Verio to NTT Communications and Purchaser.

  .  The fact that, pursuant to the Merger Agreement, between the execution
     of the Merger Agreement and Effective Time, Verio is required to obtain
     NTT Communications' consent before it can take certain actions.

  In view of the wide variety of factors considered by the Verio Board, it did
not find it practical to, and did not, quantify or otherwise assign relative
weights to the foregoing factors or determine that any factor was of
particular importance. Rather, the Verio Board viewed its position and
recommendation as being based on the totality of the information presented to
and considered by it.


                                      22
<PAGE>

  Having considered all the foregoing, and other relevant factors, the Verio
Board concluded that the Offer and the Merger, taken together, was the best
available alternative for Verio and its stockholders and was fair to and in
the best interests of holders of Preferred Stock and holders of Common Stock
(other than NTT Communications and its affiliates).

  (c) Intent to Tender.

  To Verio's knowledge after reasonable inquiry, all of Verio's executive
officers and directors currently intend to tender all Shares held of record or
beneficially (other than Shares held directly or indirectly by other public
companies, as to which Verio has no knowledge) by them pursuant to the Offer
or to vote in favor of the Merger. The foregoing does not include any Shares
over which, or with respect to which, any such executive officer or director
acts in a fiduciary or representative capacity or is subject to the
instructions of a third party with respect to such tender. Neither Verio nor
its subsidiaries intend to tender their shares pursuant to the Offer. To
Verio's knowledge, neither NTT Communications nor its subsidiaries will be
tendering their Shares pursuant to the Offer.


                                      23

Item 5. Persons/Assets Retained, Employed, Compensated or Used.

Salomon Smith Barney Inc.

  Salomon Smith Barney was retained by Verio pursuant to a letter agreement
dated April 21, 1999 (the "SSB Engagement Letter"). Salomon Smith Barney was
retained, among other things, to provide investment banking services to the
Company and to serve as the Company's financial advisor with respect to a
possible sale, transfer or other disposition to certain specified parties,
directly or indirectly, of all or substantially all of the business, assets or
at least 30% of the equity securities of Verio through a merger or
consolidation, tender or exchange offer, negotiated purchase or other business
combination of the Company.

  On May 7, 2000, at the meeting of the Verio Board, Salomon Smith Barney
delivered its oral opinion, which was subsequently confirmed in writing, to
the Verio Board to the effect that, based upon and subject to certain matters
stated therein, (a) as of May 7, 2000, the consideration to be received in the
Offer and the Merger, taken together, by holders of Common Stock was fair to
such holders (other than NTT Communications) from a financial point of view
and (b) as of May 7, 2000, the consideration to be received in the Offer and
the Merger, taken together, by holders of Preferred Stock was fair to such
holders from a financial point of view.

  Pursuant to the SSB Engagement Letter, Verio has agreed to pay Salomon Smith
Barney a fee of approximately $17 million, a substantial portion of which is
contingent upon consummation of the Merger. Verio has also agreed to reimburse
Salomon Smith Barney for its reasonable travel and other out-of-pocket
expenses incurred in connection with its engagement (including the reasonable
fees and disbursements of its counsel) and to indemnify Salomon Smith Barney
against certain liabilities and expenses relating to or arising out of its
engagement, including certain liabilities under the federal securities laws.

Item 6. Interest in Securities of the Subject Company.

  The following summary sets forth information concerning transactions in
Verio's Common Stock or Preferred Stock (i) during the past 60 days by NTT,
its directors, executive officers, affiliates and subsidiaries, and (ii)
during the past 60 days by Verio, its subsidiaries, affiliates, directors and
executive officers.

  (1) NTT Rocky, Inc., an indirectly wholly owned subsidiary of NTT, was
granted options by Verio on April 27, 2000 to purchase 6,000 shares of Common
Stock at an exercise price of $26.438 per share under Verio's 1998 Non-
Employee Director Stock Incentive Plan as a result of Yukimasa Ito's position
as a director of Verio. Mr. Ito was designated as a director pursuant to the
Investment Agreement dated as of April 7, 1998 between Verio and NTT.

  (2) On March 15, 2000, Justin L. Jaschke exercised: (i) 62,735 vested stock
options under Verio's 1996 Stock Option Plan at a price per share of $1.50 and
(ii) 14,814 vested stock options under Verio's 1998 Stock Incentive Plan at a
price per share of $6.75. On March 20, 2000, Mr. Jaschke exercised 14,814
vested stock options under Verio's 1998 Stock Incentive Plan at a price per
share of $6.75. All of these transactions were effected in New York City.

  (3) On March 17, 2000, Verio entered into an equity swap transaction in New
York City with Verio, LLC, a wholly owned unrestricted subsidiary of Verio,
and Salomon Brothers Holding Company Inc., pursuant to which Verio, LLC sold
640,000 shares of Common Stock at a price of $52.50 per share to Salomon
Brothers Holding Company Inc. for proceeds in the amount of $33,600,000. In
connection with the equity swap transaction, Verio, LLC also pledged 1,360,000
shares of Common Stock to Salomon Smith Barney pursuant to the terms of a
Pledge Agreement, dated as of March 17, 2000 (the "Pledge Agreement").

                                      24

  (4) On March 20, 2000, Steven C. Halstedt gifted 12,000 shares of Common
Stock to a donee. The transaction was effected in Chicago, Illinois.

  (5) On April 3, 2000, James C. Allen exercised 20,000 vested stock options
under Verio's 1998 Non-Employee Director Stock Incentive Plan at a price per
share of $10.75. The transaction was effected in New York City.

  (6) On April 5, 2000, the Verio Board of Directors authorized an additional
capital contribution of 1,500,000 shares of Common Stock to Verio, LLC. On
April 10, 2000, 773,000 of these 1,500,000 additional shares of Common Stock
were pledged to Salomon Smith Barney, pursuant to the terms of the Pledge
Agreement. On April 25, 2000, the remaining 727,000 shares of Common Stock
authorized for issuance to Verio, LLC were also pledged to Salomon Smith
Barney, pursuant to the terms of the Pledge Agreement. All of these
transactions were effected in New York City.

  (7) On May 12, 2000, a total of 62,915 shares of Common Stock were purchased
under the Verio 1998 Employee Stock Purchase Plan for the account of
participating employees of Verio, including the following executive officers,

Deb M. Gahan 12,000 shares of Common Stock. The price paid by Verio for the
repurchased shares was $1.50 per share, reflecting the same price Ms. Gahan
paid to exercise options to purchase the 12,000 shares of Common Stock. The
transaction was effected in Englewood, Colorado pursuant to repurchase rights
granted to Verio in connection with the early exercise by Ms. Gahan of
unvested stock options.

                                      25

Item 8. Additional Information.

Information Statement.

  The Information Statement attached as Schedule I hereto is being furnished
in connection with the possible designation by Purchaser, pursuant to the
Merger Agreement, of certain persons to be appointed to the Verio Board other
than at a meeting of the Company's stockholders as described in Item 3 above,
and is incorporated herein by reference.

State Takeover Laws.

  The Company is incorporated under the laws of the State of Delaware. In
general, Section 203 of the DGCL ("Section 203") prevents an "interested
stockholder" (including a person who owns or has the right to acquire 15% or
more of a corporation's outstanding voting stock) from engaging in a "business
combination" (defined to include mergers and certain other actions) with a
Delaware corporation for a period of three years following the date such
person became an interested stockholder unless, among other things, the
"business combination" is approved by the board of directors of such
corporation prior to such date. The Verio Board has approved the Offer and the
Merger. Accordingly, Section 203 is inapplicable to the Offer and the Merger.
A number of other states have adopted laws and regulations applicable to
attempts to acquire securities of corporations which are incorporated, or have
substantial assets, stockholders, principal executive offices or principal
places of business or whose business operations otherwise have substantial
economic effects in such states. In 1982, the Supreme Court of the United
States, in Edgar v. Mite Corp., invalidated on constitutional grounds the
Illinois Business Takeovers Statute, which as a matter of state securities law
made takeovers of corporations meeting certain requirements more difficult.
The reasoning in that decision is likely to apply to certain other state
takeover statutes. In 1987, however, in CTS Corp. v. Dynamics Corp. of
America, the Supreme Court of the United States held that the State of Indiana
could as a matter of corporate law and, in particular, those aspects of
corporate law concerning corporate governance, constitutionally disqualify a
potential acquiror from voting on the affairs of a target corporation without
the prior approval of the remaining stockholders, as long as those laws were
applicable only under certain conditions. Subsequently, in TLX Acquisition
Corp. v. Telex Corp., a federal district court in Oklahoma ruled that the
Oklahoma statutes were unconstitutional insofar as they apply to corporations
incorporated outside Oklahoma, because they would subject those corporations
to inconsistent regulations. Similarly, in Tyson Foods, Inc. v. McReynolds, a
federal district court in Tennessee ruled that four Tennessee takeover
statutes were unconstitutional as applied to corporations incorporated outside
Tennessee. This decision was affirmed by the United States Court of Appeals
for the Sixth Circuit. In December 1988, a federal district court in Florida
held, in Grand Metropolitan PLC v. Butterworth, that the provisions of the
Florida Affiliated Transactions Act and Florida Control Share Acquisition Act
were unconstitutional as applied to corporations incorporated outside of
Florida.

DGCL Section 253.

  Under Section 253 of the DGCL, if Purchaser acquires, pursuant to the Offer
or otherwise, at least 90% of the outstanding Common Stock, Purchaser will be
able to effect the Merger after consummation of the Offer without a vote by
Verio's stockholders. However, if Purchaser does not own at least 90% of the
outstanding Common Stock as a result of the Offer or otherwise, a vote by
Verio's stockholders will be required under the DGCL to effect the Merger.

Antitrust.

  Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
(the "HSR Act"), and the related rules and regulations that have been issued
by the Federal Trade Commission (the "FTC"), certain acquisition transactions
may not be consummated until certain information and documentary material has
been furnished for review by the FTC and the Antitrust Division of the
Department of Justice (the "Antitrust Division") and certain waiting period
requirements have been satisfied. These requirements apply to Purchaser's
acquisition of Shares in the Offer and the Merger.


                                      26
<PAGE>

  Under the HSR Act, the purchase of Shares in the Offer may not be completed
until the expiration of a 15-calendar-day waiting period following the filing
of certain required information and documentary material concerning the Offer
with the FTC and the Antitrust Division, unless the waiting period is earlier
terminated by the FTC and the Antitrust Division. NTT Communications and
Purchaser expect to file a Premerger Notification and Report Form under the
HSR Act with the FTC and the Antitrust Division in connection with the
purchase of Shares in the Offer and the Merger no later than May 30, 2000,
and, in that event, the required waiting period with respect to the Offer and
the Merger will expire at 11:59 p.m., New York City time, on or about June 14,
2000, unless earlier terminated by the FTC or the Antitrust Division or we
receive a request for additional information or documentary material prior to
that time. If within the 15-calendar-day waiting period either the FTC or the
Antitrust Division requests additional information or documentary material
from us, the waiting period with respect to the Offer and the Merger would be
extended for an additional period of 10 calendar days following the date of
our substantial compliance with that request. Only one extension of the
waiting period pursuant to a request for additional information is authorized
by the HSR Act rules. After that time, the waiting period could be extended
only by court order or with our consent. The FTC or the Antitrust Division may
terminate the additional 10-calendar-day waiting period before its expiration.
In practice, complying with a request for additional information or
documentary material can take a significant period of time. Although Verio is
required to file certain information and documentary material with the FTC and
the Antitrust Division in connection with the Offer, neither Verio's failure
to make those filings nor a request made to Verio from the FTC or the
Antitrust Division for additional information or documentary material will
extend the waiting period with respect to the purchase of Shares in the Offer
and the Merger.

  The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as Purchaser's acquisition of Shares
in the Offer and the Merger. At any time before or after our purchase of
Shares, the FTC or the Antitrust Division could take any action under the
antitrust laws that either considers necessary or desirable in the public
interest, including seeking to enjoin the purchase of Shares in the Offer and
the Merger, the divestiture of Shares purchased in the Offer or the
divestiture of substantial assets of NTT Communications, Verio or any of their
respective subsidiaries or affiliates. Private parties as well as state
attorneys general may also bring legal actions under the antitrust laws under
certain circumstances.

  Based upon an examination of publicly available information relating to the
businesses in which Verio is engaged, Verio believes that the acquisition of
Shares in the Offer and the Merger should not violate the applicable antitrust
laws. Nevertheless, Verio cannot be certain that a challenge to the Offer and
the Merger on antitrust grounds will not be made, or, if such challenge is
made, what the result will be.

Exon-Florio Amendment.

  Section 721 of the Defense Production Act of 1950, as amended (the "Exon-
Florio Amendment") authorizes the President of the United States or his
designee to make an investigation to determine the effects on national
security of mergers, acquisitions and takeovers by or with foreign persons
which could result in foreign control of persons engaged in interstate
commerce in the United States. The President has delegated authority to
investigate proposed transactions to the Committee on Foreign Investment in
the United States ("CFIUS").

  Reviews under the Exon-Florio Amendment are made in accordance with the
following timetable: (i) within 30 days following the receipt by CFIUS of
written notification of a proposed acquisition, CFIUS must determine whether
to commence an investigation; (ii) if CFIUS commences an investigation, it
must complete the investigation and submit a report and recommendation to the
President within 45 days following the determination to commence an
investigation; and (iii) the President has 15 days following the completion of
the investigation to take action to suspend or prohibit the relevant
acquisition.

  In order for the President to exercise his authority to suspend or prohibit
an acquisition, the President must make two findings: (i) that there is
credible evidence that leads the President to believe that the foreign
interest exercising control might take action that threatens to impair
national security and (ii) that provisions of law other than the Exon-Florio
Amendment and the International Emergency Economic Powers Act do not provide

                                      27
<PAGE>

adequate and appropriate authority for the President to protect the national
security in connection with the acquisition. The President's actions are not
subject to judicial review. If the President makes such findings, he may take
action for such time as he considers appropriate to suspend or prohibit the
relevant acquisition. The President may direct the Attorney General to seek
appropriate relief, including divestment relief, in the District Courts of the
United States in order to implement and enforce the Exon-Florio Amendment.

  Absent certain conditions, the Exon-Florio Amendment does not obligate the
parties to an acquisition to notify CFIUS of a proposed transaction. However,
if notice of a proposed acquisition is not submitted to CFIUS, then the
transaction remains indefinitely subject to review by the President under the
Exon-Florio Amendment.

  NTT Communications and Verio plan to file with CFIUS a joint notice of the
transactions contemplated by the Merger Agreement. Although NTT Communications
believes that the transactions contemplated by the Merger Agreement should not
raise any national security concerns, there can be no assurance that CFIUS
will not determine to conduct an investigation of the proposed transaction
and, if an investigation is commenced, there can be no assurance regarding the
outcome of such investigation. If the results of such investigation are
adverse to NTT Communications, Purchaser may not be obligated to accept for
payment or pay for any Shares tendered pursuant to the Offer.

Appraisal Rights.

  No appraisal rights are available in connection with the Offer. However, if
the Merger is consummated, any holder of Shares at the Effective Time (a
"Remaining Stockholder") will have certain rights under the DGCL to dissent
and demand appraisal of their Shares. Under Section 262 of the DGCL, a
Remaining Stockholder who does not wish to accept the Merger Consideration
pursuant to the Merger has the right to seek an appraisal and be paid the
"fair value" of its Shares at the Effective Time (exclusive of any element of
value arising from the accomplishment or expectation of the Merger) judicially
determined and paid to it in cash provided that such holder complies with the
provisions of Section 262 of the DGCL.

  The following is a brief summary of the statutory procedures to be followed
by a Remaining Stockholder in order to perfect appraisal rights under Delaware
law. This summary is not intended to be complete and is qualified in its
entirety by reference to Section 262 of the DGCL. Any Remaining Stockholder
considering demanding appraisal is advised to consult legal counsel. Appraisal
rights will not be available unless and until the Merger (or a similar
business combination) is consummated.

  Remaining Stockholders of record who desire to exercise their appraisal
rights must fully satisfy all of the following conditions. A written demand
for appraisal of Shares must be delivered to the Secretary of Verio (x) before
the taking of the vote on the adoption of the Merger Agreement if the Merger
is not being effected as a short-form merger but rather is being consummated
following approval thereof at a meeting of Verio's stockholders (a "long-form
merger") or (y) within 20 days after the date that the Surviving Corporation
mails to the Remaining Stockholders a notice (the "Notice of Merger") to the
effect that the Merger is effective and that appraisal rights are available
(and includes in such notice a copy of Section 262 of the DGCL and any other
information required thereby) if the Merger is being effected as a short-form
merger without a vote or meeting of Verio's stockholders. If the Merger is
effected as a long-form merger, the written demand for appraisal of Shares
must be in addition to and separate from any proxy or vote abstaining from or
voting against the adoption of the Merger Agreement, and neither voting
against, abstaining from voting, nor failing to vote on the Merger Agreement
will constitute a demand for appraisal within the meaning of Section 262 of
the DGCL. In the case of a long-form merger, any stockholder seeking appraisal
rights must hold the Shares for which appraisal is sought on the date of the
making of the demand, continuously hold such Shares through the Effective
Time, and otherwise comply with the provisions of Section 262 of the DGCL.

  In the case of both a short-form merger and a long-form merger, a demand for
appraisal must be executed by or for the stockholder of record, fully and
correctly, as such stockholder's name appears on the stock certificates. If
Shares are owned of record in a fiduciary capacity, such as by a trustee,
guardian or custodian,

                                      28
<PAGE>

such demand must be executed by the fiduciary. If Shares are owned of record
by more than one person, as in a joint tenancy or tenancy in common, such
demand must be executed by all joint owners. An authorized agent, including an
agent for two or more joint owners, may execute the demand for appraisal for a
stockholder of record; however, the agent must identify the record owner and
expressly disclose the fact that, in exercising the demand, he is acting as
agent for the record owner.

  A record owner, such as a broker, who holds Shares as a nominee for others,
may exercise appraisal rights with respect to the Shares held for all or less
than all beneficial owners of Shares as to which the holder is the record
owner. In such case the written demand must set forth the number of Shares
covered by such demand. Where the number of Shares is not expressly stated,
the demand will be presumed to cover all Shares outstanding in the name of
such record owner. Beneficial owners who are not record owners and who intend
to exercise appraisal rights should instruct the record owner to comply
strictly with the statutory requirements with respect to the exercise of
appraisal rights before the date of any meeting of stockholders of Verio
called to approve the Merger in the case of a long-form merger and within 20
days following the mailing of the Notice of Merger in the case of a short-form
merger.

  Remaining Stockholders who elect to exercise appraisal rights must mail or
deliver their written demands to: Secretary, Verio Inc., 8005 South Chester
Street, Suite 200, Englewood, Colorado 80112. The written demand for appraisal
should specify the stockholder's name and mailing address, the number of
Shares covered by the demand and that the stockholder is thereby demanding
appraisal of such Shares. In the case of a long-form merger, Verio must,
within ten days after the Effective Time, provide notice of the Effective Time
to all stockholders who have complied with Section 262 of the DGCL and have
not voted for approval and adoption of the Merger Agreement.

  In the case of a long-form merger, Remaining Stockholders electing to
exercise their appraisal rights under Section 262 must not vote for the
adoption of the Merger Agreement or consent thereto in writing. Voting in
favor of the adoption of the Merger Agreement, or delivering a proxy in
connection with the stockholders meeting called to adopt the Merger Agreement
(unless the proxy votes against, or expressly abstains from the vote on, the
adoption of the Merger Agreement), will constitute a waiver of the
stockholder's right of appraisal and will nullify any written demand for
appraisal submitted by the stockholder.

  Regardless of whether the Merger is effected as a long-form merger or a
short-form merger, within 120 days after the Effective Time, either Verio or
any stockholder who has complied with the required conditions of Section 262
and who is otherwise entitled to appraisal rights may file a petition in the
Delaware Court of Chancery demanding a determination of the fair value of the
Shares of the dissenting stockholders. If a petition for an appraisal is
timely filed, after a hearing on such petition, the Delaware Court of Chancery
will determine which stockholders are entitled to appraisal rights and
thereafter will appraise the Shares owned by such stockholders, determining
the fair value of such Shares, exclusive of any element of value arising from
the accomplishment or expectation of the Merger, together with a fair rate of
interest to be paid, if any, upon the amount determined to be the fair value.
In determining fair value, the Delaware Court of Chancery is to take into
account all relevant factors. In Weinberger v. UOP, Inc., et al., the Delaware
Supreme Court discussed the factors that could be considered in determining
fair value in an appraisal proceeding, stating that "proof of value by any
techniques or methods which are generally considered acceptable in the
financial community and otherwise admissible in court" should be considered
and that "[f]air price obviously requires consideration of all relevant
factors involving the value of a company." The Delaware Supreme Court stated
that in making this determination of fair value the court must consider
"market value, asset value, dividends, earnings prospects, the nature of the
enterprise and any other facts which were known or which could be ascertained
as of the date of merger which throw any light on future prospects of the
merged corporation ......" The Delaware Supreme Court has construed Section 262
of the DGCL to mean that "elements of future value, including the nature of
the enterprise, which are known or susceptible of proof as of the date of the
merger and not the product of speculation, may be considered." However, the
court noted that Section 262 provides that fair value is to be determined
"exclusive of any element of value arising from the accomplishment or
expectation of the merger."


                                      29
<PAGE>

  Remaining Stockholders who in the future consider seeking appraisal should
have in mind that the fair value of their Shares determined under Section 262
could be more than, the same as, or less than the Merger Consideration or the
Preferred Merger Consideration, as the case may be, if they do seek appraisal
of their Shares, and that opinions of investment banking firms as to fairness
from a financial point of view are not necessarily opinions as to fair value
under Section 262 of the DGCL. Moreover, NTT Communications intends to cause
the Surviving Corporation to argue in any appraisal proceeding that, for
purposes thereof, the "fair value" of the Shares is less than that paid in the
Offer. The cost of the appraisal proceeding may be determined by the Delaware
Court of Chancery and taxed upon the parties as the Delaware Court of Chancery
deems equitable in the circumstances. Upon application of a dissenting
stockholder, the Delaware Court of Chancery may order that all or a portion of
the expenses incurred by any dissenting stockholder in connection with the
appraisal proceeding, including, without limitation, reasonable attorneys'
fees and the fees and expenses of experts, be charged pro rata against the
value of all Shares entitled to appraisal. In the absence of such a
determination or assessment, each party bears its own expenses.

  Any Remaining Stockholder who has duly demanded appraisal in compliance with
Section 262 of the DGCL will not, after the Effective Time, be entitled to
vote for any purpose the Shares subject to such demand or to receive payment
of dividends or other distributions on such Shares, except for dividends or
other distributions payable to stockholders of record at a date prior to the
Effective Time.

  At any time within 60 days after the Effective Time, any former holder of
Shares shall have the right to withdraw his or her demand for appraisal and to
accept the Merger Consideration. After this period, such holder may withdraw
his or her demand for appraisal only with the consent of Verio as the
Surviving Corporation. However, no petition timely filed in the Delaware Court
of Chancery demanding appraisal shall be dismissed as to any stockholder
without the approval of the Delaware Court of Chancery, and such approval may
be conditioned upon such terms as the Delaware Court of Chancery deems just.
If no petition for appraisal is filed with the Delaware Court of Chancery
within 120 days after the Effective Time, stockholder's rights to appraisal
shall cease and all stockholders shall be entitled to receive the Merger
Consideration or the Preferred Merger Consideration, as the case may be.
Inasmuch as Verio has no obligation to file such a petition, and NTT
Communications has no present intention to cause or permit the Surviving
Corporation to do so, any stockholder who desires such a petition to be filed
is advised to file it on a timely basis.

  Failure to take any required step in connection with the exercise of
appraisal rights may result in the termination or waiver of such rights.

  APPRAISAL RIGHTS CANNOT BE EXERCISED AT THIS TIME. THE INFORMATION SET FORTH
ABOVE IS FOR INFORMATIONAL PURPOSES ONLY WITH RESPECT TO ALTERNATIVES
AVAILABLE TO STOCKHOLDERS IF THE MERGER IS CONSUMMATED. STOCKHOLDERS WHO WILL
BE ENTITLED TO APPRAISAL RIGHTS IN CONNECTION WITH THE MERGER WILL RECEIVE
ADDITIONAL INFORMATION CONCERNING APPRAISAL RIGHTS AND THE PROCEDURES TO BE
FOLLOWED IN CONNECTION THEREWITH BEFORE SUCH STOCKHOLDERS HAVE TO TAKE ANY
ACTION RELATING THERETO.

  STOCKHOLDERS WHO SELL SHARES IN THE OFFER WILL NOT BE ENTITLED TO EXERCISE
APPRAISAL RIGHTS WITH RESPECT THERETO BUT, RATHER, WILL RECEIVE THE PRICE PAID
IN THE OFFER THEREFOR.

Certain Litigation Matters.

  Three complaints, entitled Rosner v. Verio Inc., et al., Weinstock v.
Halstedt, et al., and Brett v. Halstedt, et al., were filed in the Court of
Chancery of the State of Delaware in New Castle County against Verio, NTT and
directors of Verio, as purported class actions. The Rosner and Weinstock
actions were filed on May 8, 2000 and the Brett action was filed on May 10,
2000. A fourth purported class action, entitled Wolk v. Cahoon, et al., was
filed against Verio and directors of Verio, in the Court of Chancery of the
State of Delaware in New Castle County on May 8, 2000. On May 9, 2000, a fifth
purported class action, entitled Cody v. Verio Inc., et al., was filed in the
Colorado State District Court, County of Arapahoe against Verio and directors
of Verio.


                                      30
<PAGE>

  The Rosner, Weinstock, Brett and Wolk complaints (collectively, the
"Delaware Class Complaints"), seek compensatory and rescissiory damages and
injunctive relief based on the Merger Agreement. The Cody action
seeks preliminary and permanent injunctive relief and declaratory relief. The
Delaware Class Complaints and Cody action also seek costs and disbursements,
and attorneys' and experts' fees in connection with their claims.

  The Delaware Class Complaints and Cody action allege, among other things,
that the individual defendants breached their fiduciary duties by failing to
properly determine Verio's value as a merger candidate, failing to conduct an
appropriate auction or market check or to invite other bidders and failing to
obtain adequate consideration for Verio's common stock.

  NTT, Verio and the individual defendants believe that these complaints are
meritless and they will be defended vigorously.

            INFORMATION STATEMENT PURSUANT TO SECTION 14(f) OF THE
           SECURITIES EXCHANGE ACT OF 1934 AND RULE 14f-1 THEREUNDER

  This Information Statement is being mailed on or about May 17, 2000, as a
part of the Solicitation/Recommendation Statement on Schedule 14D-9 (the
"Schedule 14D-9") of Verio Inc. ("Verio" or the "Company") with respect to the
tender offer by Chaser Acquisition, Inc. ("Purchaser"), a Delaware corporation
and an indirect wholly-owned subsidiary of NTT Communications Corporation, a
limited liability joint stock company incorporated under the laws of Japan
("NTT Communications"), a wholly-owned subsidiary of Nippon Telegraph and
Telephone Corporation, a limited liability joint stock company incorporated
under the laws of Japan ("NTT"), to the holders of record of shares of Common
Stock, par value $.001 per share, of the Company (the "Common Stock") and to
the holders of record of shares of Series A 6.75% Convertible Preferred Stock,
par value $.001 per share, of the Company (the "Preferred Stock" and together
with the Common Stock, the "Shares"). Capitalized terms used and not otherwise
defined herein shall have the meaning set forth in the Schedule 14D-9. You are
receiving this Information Statement in connection with the possible election
of persons designated by NTT Communications to a majority of the seats on the
Board of Directors of the Company (the "Board" or the "Verio Board").

  The Merger Agreement provides that promptly after such time as Purchaser
acquires Shares pursuant to the Offer, Purchaser will be entitled to the
fullest extent permitted by law to designate at its option up to that number
of directors (rounded to the nearest whole number) of the Verio Board, subject
to compliance with Section 14(f) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), as will make the percentage of Verio's directors
designated by Purchaser equal to the percentage of the aggregate voting power
of the shares of Common Stock held by NTT Communications or any of its
subsidiaries. However, in the event that Purchaser's designees are elected to
the Verio Board, until the Effective Time, the Verio Board shall have at least
three directors who were directors of Verio on the date of the Merger
Agreement (the "Continuing Directors"). If the number of Continuing Directors
shall be reduced below three for any reason whatsoever, the remaining
Continuing Directors shall designate a person or persons to fill such vacancy
or vacancies, each of whom shall be deemed to be a Continuing Director for
purposes of the Merger Agreement or, if no Continuing Directors then remain,
the other directors of Verio shall designate three persons to fill such
vacancies who shall not be officers or affiliates of Verio or any of its
subsidiaries, or officers or affiliates of NTT Communications or any of its
subsidiaries, and such persons shall be deemed to be Continuing Directors for
purposes of the Merger Agreement and, in either case, Purchaser shall cause
such person or persons to be elected to fill such vacancy or vacancies.

  Following the election or appointment of Purchaser's designees to the Verio
Board and prior to the Effective Time, any amendment, or waiver of any term or
condition, of the Merger Agreement or Verio's Certificate of Incorporation or
Bylaws, any termination of the Merger Agreement by Verio, any extension by
Verio of the time for the performance of any of the obligations or other acts
of Purchaser or NTT Communications or waiver or assertion of any of Verio's
rights under the Merger Agreement, and any other consent or action by the
Verio Board with respect to the Merger Agreement, will require the concurrence
of a majority of the Continuing Directors and, except as required by
applicable law, no other action by Verio, including any action by any other
director of Verio, shall be required for purposes of the Merger Agreement. To
the fullest extent permitted by law, Verio will take all actions requested by
NTT Communications and reasonably necessary to effect such election. In
connection with the foregoing, Verio will promptly, at the option of NTT
Communications, to the fullest extent permitted by law, Verio's Certificate of
Incorporation and Verio's Bylaws, either increase the size of the Verio Board
and/or obtain the resignation of such number of its current directors as is
necessary to enable Purchaser's designees to be elected or appointed to the
Verio Board as provided above.

  This Information Statement is required by Section 14(f) of the Exchange Act
and Rule 14f-1 thereunder in connection with the appointment of Purchaser's
designees to the Verio Board.

                                       1
<PAGE>

  You are urged to read this Information Statement carefully. You are not,
however, required to take any action.

  Pursuant to the Merger Agreement, Purchaser commenced the Offer on May 17,
2000. The Offer is scheduled to expire at midnight, New York City time, on
June 14, 2000, unless the Offer is extended, at which time, if all conditions
to the Offer have been satisfied or waived, Purchaser will purchase all of the
Shares validly tendered pursuant to the Offer and not properly withdrawn.

  The information contained in this Information Statement (including
information incorporated by reference) concerning NTT Communications,
Purchaser and Purchaser's designees has been furnished to the Company by NTT
Communications, and the Company assumes no responsibility for the accuracy or
completeness of such information.

                              PURCHASER DESIGNEES

  NTT Communications has informed the Company that it will choose Purchaser's
designees from the executive officers of NTT Communications listed in Schedule
I of the Offer to Purchase, a copy of which is being mailed to stockholders of
the Company. The information with respect to such officers in Schedule I is
hereby incorporated by reference. NTT Communications has informed the Company
that each of the officers listed in Schedule I of the Offer to Purchase has
consented to act as a director of the Company, if so designated.

  Based solely on the information set forth in Schedule I of the Offer to
Purchase filed by Purchaser, none of the executive officers and directors of
NTT Communications or Purchaser (i) is currently a director of, or holds any
position with, the Company (other than Yukimasa Ito, who is an officer of NTT
Communications), or (ii) has a familial relationship with any directors or
executive officers of the Company. The Company has been advised that, to the
best knowledge of NTT Communications and Purchaser, none of NTT
Communications' or Purchaser's directors or executive officers beneficially
owns any equity securities (or rights to acquire such equity securities) of
the Company and none have been involved in any transactions with the Company
or any of its directors, executive officers, affiliates or associates which
are required to be disclosed pursuant to the rules and regulations of the
Securities and Exchange Commission.

  It is expected that Purchaser's designees may assume office at any time
following the purchase by Purchaser of a specified minimum number of Shares
pursuant to the Offer, which purchase cannot be earlier than June 15, 2000,
and that, upon assuming office, Purchaser's designees will thereafter
constitute at least a majority of the Board. This step will be accomplished at
a meeting or by written consent of the Board providing that the size of the
Board will be increased and/or sufficient numbers of current directors will
resign such that, immediately following such action, the number of vacancies
to be filled by Purchaser's designees will constitute at least a majority of
the available positions on the Board. It is currently not known which of the
current directors of the Company will resign.

                     CERTAIN INFORMATION CONCERNING VERIO

  The authorized capital stock of the Company consists of (a) 750,000,000
shares of Common Stock and (b) 20,000,000 shares of Preferred Stock. As of the
close of business on May 11, 2000, there were 82,615,431 shares of Common
Stock and 7,200,000 shares of Preferred Stock issued and outstanding
(including 2,860,000 shares of Common Stock held by a subsidiary of Verio).
The Company's Bylaws authorize the number of directors to be not less than
five nor more than eleven. The Board currently consists of eight members, with
one vacancy.

  Each share of Common Stock entitles the record holder to one vote. Shares of
Preferred Stock have no voting rights except as provided by law and by the
Company's Certificate of Designations for the Preferred Stock. The Company's
Board of Directors is divided into three classes: Class I, Class II and Class
III. Each class serves staggered terms with the initial term of each class
expiring, respectively, at the first, second and third succeeding annual
meeting of the stockholders of the Company held following the Company's
initial public offering in May 1998. The Board is currently composed three
Class III Directors (Messrs. Justin L. Jaschke, Trygve E. Myhren and Yukimasa
Ito), whose terms will expire upon the election and qualification of directors
at

                                       2
<PAGE>

the annual meeting of stockholders to be held in 2001; and three Class I
Directors (Messrs. Arthur L. Cahoon, Thomas A. Marinkovich and Paul J. Salem),
whose terms will expire upon the election and qualification of directors at
the annual meeting of stockholders to be held in 2002 and two Class II
Directors (Messrs. Steven C. Halstedt and James C. Allen), whose terms will
expire in 2003. At each annual meeting of stockholders, directors will be
elected for full terms of three years to succeed those directors whose terms
are expiring.

  Set forth below are the name, age and position of each director, executive
officer and certain other members of senior management of the Company.

Directors' Compensation

  During calendar year 1999, each non-employee director received an annual
retainer fee of $5,000 and a fee of $1,000 for each meeting of the Board
attended in person or $500 for each meeting attended by telephone. The fee for
Board committee meetings was $500 per meeting, whether attended in person or
by telephone. A director may elect to receive these payments in the form of
common stock. In April 1998, the Company adopted the 1998 Non-Employee
Director Stock Incentive Plan ("Director Option Plan") under which options may
be granted and shares of Common Stock may be issued to non-employee directors
in order to better attract and retain highly qualified outside directors.
Under the terms of the Director Option Plan, upon the effective date of the
registration statement filed with the SEC in connection with the Company's
initial public offering, each non-employee director was automatically granted
an option to acquire 60,000 shares of Common Stock at an exercise price per
share equal to the price per share in the initial public offering of the
Common Stock less underwriting discounts and commissions. Such options vest
and become exercisable in three equal installments on each yearly anniversary
of the grant date. Non-employee directors elected or appointed to the Board
following the initial public offering at the time of their election or
appointment also were automatically granted an option to acquire 60,000 shares
of Common Stock with the same terms and conditions at an exercise price equal
to the then fair market value of the Common Stock. In accordance with these
terms, on May 11, 1998 (the effective date of the Company's initial public
offering registration statement), each of Messrs. Halstedt, Allen, Myhren and
Salem were granted options to purchase 60,000 shares of Common Stock, at an
exercise price of $10.75 per share under the Director Option Plan. (That
number of shares and the exercise price have been adjusted to reflect the
Company's two-for-one Common Stock split that was effected on August 20,
1999.) Thereafter, automatically on their respective appointments to the
Board, on September 11, 1998, Mr. Ito was granted an option to purchase 60,000
shares of Common Stock, at an exercise price of $10.25 per share, and on
January 5, 1999, Mr. Cahoon was granted an option to purchase 60,000 shares of
Common Stock, at an exercise price of $11.375 per share, under the Director
Option Plan. Each of Messrs. Halstedt, Myhren, Salem, Ito and Cahoon have
assigned their respective options to Centennial Holdings, Inc., Myhren Media,
Inc., Providence Equity Partners Inc., NTT Rocky, Inc. and the Arthur L.
Cahoon Investments Trust, UA 12/23/99, David A. Damico, Trustee, respectively.

  Under the initial terms of the Director Option Plan, after the initial three
year vesting period for the automatic 60,000 options, non-employee directors
would receive automatic annual grants of options to acquire an additional
6,000 shares of Common Stock at an exercise price equal to the fair market
value of the Common Stock at the date of grant. Such additional options vest
and become exercisable on the first anniversary of the grant date.

  On December 15, 1999, the Compensation Committee adopted a proposal to
modify the non-employee director compensation policy, effective as of January
1, 2000, increasing the annual retainer fee from $5,000 to $15,000 (paid
quarterly), while eliminating the payment of all individual Board and
committee meeting fees. Non-employee Board members still have the ability to
elect annually to apply the retainer fee to the automatic purchase of the
Company's Common Stock. The Compensation Committee also recommended that the
Director Option Plan be amended to provide for an initial grant of 50,000
stock options when a new Board member is appointed to the Board, with these
options vesting over the same three-year period as under the initial plan
terms, and with subsequent annual grants of 6,000 options being made annually
beginning with the first annual stockholders meeting to take place following a
Board member's first full year of service on the Board (i.e., without waiting
until the initial grant is fully vested). Both of these proposals were
approved by the Board on December 16, 1999.

  Under the terms of the Director Option Plan, the Offer would cause (i) each
initial option grant that is at the time outstanding to automatically vest as
to one-third of the total number of shares subject to such option, and (ii)
each subsequent option grant that is at the time outstanding to automatically
vest as to all of the shares subject to such option. In connection with the
approval of the transactions under the Merger Agreement, the Board of
Directors of the Company authorized upon consummation of the Merger (i) the
complete acceleration of all unvested options for non-employee Directors who
have served on the Board for more than one year as of the date of the
corporate transaction and (ii) acceleration of the vesting of one-half of the
unvested options held by Directors who have served on the Board for less than
one year as of the date of the corporate transaction.

                 EXECUTIVE COMPENSATION AND OTHER INFORMATION
                       CONCERNING DIRECTORS AND OFFICERS

Executive Compensation

The following table sets forth certain summary information for the years ended
December 31, 1999, 1998 and 1997, respectively, concerning the compensation
paid and awarded to (a) the Company's Chief Executive Officer and (b) the
Company's four most highly compensated executive officers whose salaries and
bonuses exceeded $100,000 who were serving as executive officers as of
December 31, 1999. These individuals are referred to collectively as the
"Named Executive Officers."

  As part of the Company's standard cash compensation package offered to all
employees (including the Named Executive Officers), the Company provides
targeted annual cash bonuses, the payment of which is based on the Company's
overall achievement of performance goals established by the Board at the
beginning of the year. Actual performance by the Company is measured against
those goals at or following the end of the year, and the actual amount of the
targeted bonus levels paid is determined based on actual performance relative
to those objectives.

  Salary information for 1997 for Mr. Fritzinger and for 1998 for Mr. Hribar
reflect compensation paid to each in his principal position commencing in June
1997 and July 1998, respectively. The bonus amount paid to Mr. Hribar in 1988
includes a signing bonus of $125,000, plus a "gross up" for taxes, paid by the
Company at the time of his initial employment in July 1998. Information shown
under "All Other Compensation" represents the cost of providing relocation
benefits to Messrs. Hribar and Fritzinger.

Employment Agreements

  As a general matter, the Company does not enter into employment agreements,
and has not entered into employment agreements with any of its officers.
Rather, the employment relationship with each officer is "at will." However,
in connection with the initial employment of each officer, the Company and the
officer execute an offer letter in which the general compensation and benefits
provided to the officer are outlined, including base salary, targeted annual
bonus, option grants, employee benefits and severance. The compensation levels
established in such offer letters are subject to change from time to time at
the discretion of the Compensation Committee.

Compensation Protection Agreements and Subsequent Letter Agreements

  During 1998 and 1999, the Company entered into compensation protection
agreements with Justin L. Jaschke, Chris J. DeMarche, Carla Hamre Donelson,
Sean G. Brophy, Peter B. Fritzinger, James M. Keiffer, Isabel Ehringer,
Barbara L. Goworowski, Douglas R. Schneider, James P. Treuting and Mark A.
Orland, each an officer of the Company. Each of the compensation protection
agreements contain substantially similar terms, except that Justin Jaschke is
entitled to a greater amount of severance, as described below. The
compensation protection agreements are for a term of three years, subject to
automatic yearly extensions. In no event will the compensation protection
agreements terminate within 12 months of a change in control of the Company.
For purposes of the compensation protection agreements, a "change in control"
includes, among other things, any of the following:

  .  An acquisition, other than directly from the Company, of any voting
     securities of the Company by any person immediately after which such
     person has beneficial ownership (as defined in the Exchange Act) of 40%
     or more of the combined voting power of the Company's then outstanding
     voting securities. In determining whether a change in control has
     occurred, voting securities which are acquired in a "non-control
     acquisition," as defined in the compensation protection agreements, do
     not constitute an acquisition which would cause a change in control;

  .  If the individuals who, as of the date the compensation protection
     agreements were approved by the Board, were members of the Board, cease
     for any reason to constitute at least a majority of the Board (subject
     to certain provisos);

  .  Approval by stockholders of the Company of a merger, consolidation or
     reorganization involving the Company, unless such merger, consolidation
     or reorganization satisfies certain specified conditions;

  .  Any other event that at least two-thirds of the incumbent Board in its
     sole discretion determines constitutes a change in control; and

  .  If a protected officer's employment is terminated prior to a change in
     control and the Board determines that such termination was at the
     request of a third party who has indicated an intention or taken steps
     reasonably calculated to effect a change in control and who subsequently
     effectuates a change in control, or that such termination occurred in
     connection with, or in anticipation of, a change in control which
     actually occurs, then a change in control is considered to have occurred
     with respect to that protected officer, immediately prior to the date of
     such termination.

  If the Offer is consummated, a "change in control" will be deemed to have
occurred for purposes of the compensation protection agreements. As a result,
in the following circumstances involving termination of employment within 12
months following such change in control, a protected officer who is so
terminated will receive the following compensation and benefits:

  .  If a protected officer's employment with the Company is terminated for
     cause or by reason of the protected officer's disability (each as
     defined in the compensation protection agreements), death or retirement,
     or by the protected officer other than for good reason (as defined in
     the compensation protection agreements), then the Company must pay to
     the protected officer accrued compensation due

                                      13
<PAGE>

     but not paid through the date of termination. Accrued compensation
     includes, without limitation, base salary, reimbursement for reasonable
     and necessary expenses incurred by the protected officer on behalf of
     the Company during the period ending on the termination date, and
     vacation pay.

  .  If a protected officer's employment is terminated within 12 months of a
     change in control for any other reason than specified above, the
     protected officer will receive:

    .  his or her accrued compensation;

    .  an amount equal to a fraction, the numerator of which is the number
       of days in the Company's fiscal year through the termination date and
       the denominator of which is 365, multiplied by the protected
       officer's bonus amount, which is the greater of 100% of the last
       annual incentive payment paid or payable to the protected officer
       prior to the termination date, and the protected officer's incentive
       target for the fiscal year in which the change in control occurs;

    .  an amount equal to two times the sum of the protected officer's
       annual base salary in effect immediately prior to the change in
       control, plus the bonus amount paid pursuant to the immediately
       preceding provision (except that the amount paid to Mr. Jaschke will
       be three times that sum);

    .  until the third anniversary of the termination date, the same rights
       with respect to benefits provided by the Company as were provided to
       the protected officer as of the effective date of the compensation
       protection agreement, or, if greater, at any time within 90 days
       preceding the date of the change in control; and

    .  the immediate vesting and removal of all restrictions on any
       outstanding incentive awards granted to the protected officer under
       the Company's stock option and other stock incentive plans or any
       other incentive plan or arrangement, the immediate vesting and
       exercisability of all stock options and stock appreciation rights
       granted to the protected officer and the immediate vesting of all
       performance units granted to the protected officer.

  The compensation protection agreements further provide that the protected
officers are not required to mitigate the amount of any payment by seeking
employment or otherwise. The compensation protection agreements contain a
"gross-up" provision pursuant to which any payment which would subject the
protected officer to certain "golden parachute" excise taxes would include an
additional gross-up payment resulting in the protected officer retaining an
additional amount equal to these excise taxes.

  Simultaneously with the execution of the Merger Agreement, the Company
entered into letter agreements with each officer party to a compensation
protection agreement which amended the compensation protection agreements in
certain respects. The letter agreements amend the compensation protection
agreements to limit the circumstances under which an officer can receive the
severance benefits described above due to the officer's termination of
employment within 12 months following a change of control for "good reason".
The letter agreements also entitle each protected officer who remains
continuously employed by the Company to receive cash bonus payments thirteen
months after the date the Offer is consummated and twenty-five months after
the date the Offer is consummated. Each cash bonus payment will be equal to
50% of the following amount: two times (three times in the case of Justin
Jaschke) the sum of (i) the protected officer's base salary in effect
immediately prior to the consummation of the Offer, including amounts then
deferred under the Company's qualified and non-qualified employee benefit
plans, and (ii) the greater of 100% of the last annual incentive payment paid
or payable to the protected officer prior to the consummation of the Offer
under the Company's cash bonus incentive plan or the protected officer's
incentive target for the fiscal year in which the Offer is consummated. The
letter agreements do not affect the provisions for gross-up payments for
"golden parachute" excise taxes. Payments under the amended compensation
protection agreements continue to be subject to excise tax gross-up
protection. The amounts that may become payable to the protected officer
pursuant to the benefit awards to be granted as of the Effective Time under
certain retention and incentive plans to be adopted by the Company in
accordance with the Merger Agreement will be reduced by the amounts of these
cash bonus payments.


                                      14
<PAGE>

  The letter agreements further provide that the protected officers' continued
employment by the Company after consummation of the Offer and their
participation in the incentive and retention programs thereafter are subject
to the protected officers' execution prior to consummation of the Offer of
agreements to remain employed by the Company immediately after the
consummation of the Offer, covenants not to compete with or solicit employees
of the Company and its affiliates in the United States for certain designated
periods and confidentiality agreements, in each case reasonably satisfactory
to NTT Communications and the Company.

  The letter agreements also require certain protected officers to enter into
stock option deferral agreements prior to the consummation of the Offer which
waive acceleration and defer vesting of 20% of the unvested options held by
such protected officers that otherwise would become vested immediately prior
to the consummation of the Offer. Under the option deferral agreements, the
right to receive the value of the deferred options generally will vest as to
one-half of the deferred options 13 months after consummation of the Offer and
as to the remaining one-half 25 months after the Offer, provided the protected
officer is employed by Verio on that date. The option deferral agreements also
provide for the payments of bonuses to the protected officers if and when they
receive payments for the value of the deferred options. The bonus payable at
the end of 13 months will be 50% of the aggregate option consideration payable
with respect to the deferred options vesting on such date and the bonus
payable at the end of 25 months will be 100% of the aggregate option
consideration payable with respect to the deferred options vesting on such
date.

  The letter agreements, including the amendments to the compensation
protection agreements, cease to become effective upon termination of the
Merger Agreement pursuant to its terms.

            COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

  Notwithstanding anything to the contrary set forth in any of the Company's
previous filings under the Securities Act of 1933, as amended, or the Exchange
Act, that might incorporate future filings, in whole or in part, the following
report and the Performance Graph which follows shall not be deemed to be
incorporated by reference into any such filings.

  The Compensation Committee of the Board, which is comprised solely of
independent, non-employee Board members, has the authority and responsibility
to establish the overall compensation strategy for the Company, including
salary and bonus levels, to administer the Company's incentive compensation
and benefit plans, 401(k) plans, and stock option and purchase plans, and to
review and make recommendations to the Board with respect to the compensation
of the Company's executives. Trygve Myhren and Arthur Cahoon are the current
members of the Compensation Committee.

Compensation Policy

  The Company's overall compensation philosophy is to provide a competitive
compensation program that enables the Company to attract, reward, incent, and
retain highly capable executives and other employees who have the skills and
experience necessary to promote the short and long-term financial performance
and growth of the Company. The Company's compensation program is designed to
link the annual compensation received by its executives to the Company's
financial performance, growth and achievement of other strategic and
operational goals established annually by the Company's Board. In addition,
the Company's officers receive longer-term incentives, provided principally in
the form of stock options, thereby aligning their interests with those of the
Company's stockholders.

  The Company's executive compensation consists of three principal components,
the amounts of which are established in order to provide overall compensation
that is comparable to that offered by similarly situated companies. These
components include:

  .  a base salary;

  .  an annual cash bonus opportunity that is dependent on the achievement of
     company-wide performance objectives established annually by the Board;
     and

                                      15
<PAGE>

  .  awards of stock options to provide a long-term incentive that aligns
     management's interests with stockholders' interests.

  During 1999, the Compensation Committee engaged an independent consulting
firm to evaluate its overall compensation program to determine its
competitiveness and appropriateness based on an analysis of the compensation
programs and levels of other comparable companies. Specifically, the
consultant evaluated the salary, bonus and long-term incentive levels of the
Company's officers, comparing the levels paid by the Company to its officers
to those levels paid by numerous other similarly situated companies. This
comparison took into account relative market capitalization, industry, revenue
and growth levels, and other relevant factors for the Company and the
comparison companies. Based on this evaluation, and the recommendations of the
consultant resulting from this evaluation, the Compensation Committee
determined that certain compensation adjustments, both to annual salary and
option levels, were appropriate for certain executive officers as well as
other employees. As a result, certain salary levels were adjusted and
additional option grants were made during 1999 to executive officers. Details
of the stock options granted to certain executive officers in 1999 are
provided in the table entitled "Stock Options Granted in 1999" below.

  Salary. The base salaries of the Company's executive officers are initially
established, and thereafter periodically reviewed and adjusted, by the
Compensation Committee. When setting and adjusting base salary levels, in a
manner consistent with the Compensation Committee's policy outlined above, the
Compensation Committee takes into account, in addition to the performance of
the individual executive officer, which is the primary consideration, other
relevant factors such as competitive market conditions for executive
compensation, the Company's financial and stock price performance, historical
compensation levels, and internal comparability considerations.

  Bonus. Each executive officer (as well as each employee of the Company
generally) is provided an annual cash bonus opportunity that is typically a
targeted percentage of base salary. At the beginning of each year, the Board
establishes performance objectives for the year. The actual amount of the
bonus paid is determined at the end of the year based on the Company's actual
performance against those objectives. While the specific performance
objectives vary from year to year, the general approach in establishing the
objectives is to (1) foster a single company attitude across the Company's
operations, (2) emphasize the importance of teamwork and the interdependent
efforts required for success while also recognizing individual performance,
(3) compensate based on actual results measured against established goals, and
(4) provide fair, objective and easily measurable performance parameters.

  For the year ended December 31, 1999, the performance objectives established
for the payment of bonuses were based primarily on the achievement of
specific, internally established, financial performance thresholds determined
at the beginning of the year that were based on projected revenue and EBITDA
levels to be reached by year end. In evaluating the Company's actual
performance against the designated objectives for the year, the Compensation
Committee determined that the Company's actual performance against the
internally targeted financial criteria warranted payment of bonuses at 80% of
the full targeted levels. The Committee determined that at the more senior
employee level, including management, bonuses will be paid in the form of
fully vested stock option grants, while the remaining employees will receive
their bonuses paid 60% in cash and 40% in fully vested stock options. It is
anticipated that these option grants will be made during the first half of
2000. In keeping with the requirements of the Company's 1998 Stock Incentive
Plan, these option grants will be at an exercise price equal to the trading
price of the Company's Common Stock at the time of the grant. The number of
options that will be granted will be based on a formula of six options for
every $100 of bonus, a formula that was derived based in part on a Black
Sholes valuation methodology applied to the options. The Board or the
Compensation Committee in the future will continue to establish performance
criteria with respect to bonuses paid to executive officers for any given
fiscal year, which will vary based on the Company's operations, prospects and
strategy at the time.

  Long-term Incentive Compensation. The Company believes that stock option
grants:

  .  align executive officer interests with stockholder interests by creating
     a direct link between compensation and stockholder return;

  .  give executive officers a significant, long-term interest in the
     Company's success;

  .  provide each executive officer with a significant incentive to manage
     the Company's operations from the perspective of an owner with an equity
     stake in the business; and

  .  help retain key executive officers in a competitive market for executive
     talent.

  The Company's Stock Incentive Plan authorizes the Board, or a committee of
the Board, to grant stock options to employees, directors, consultants and
executive officers of the Company. Stock option grants generally are made to
all of the Company's employees, including executive officers, at the time of
initial employment. Thereafter, additional grants may be made to individual
employees, including executive officers, from time to time, in order to
continue to incent retention and long-term performance. Additional options are
not necessarily granted to each executive officer during each year, but rather
are made based on factors such as individual performance, the Company's
overall growth and financial performance, the number of unvested options held
by the individual at the time, and various competitive factors. The relative
weight given to these various factors may vary from individual to individual,
at the Committee's discretion.

  Options granted to executive officers generally are subject to vesting
provisions, so that the options vest over a four-year period, in equal annual
increments beginning on the first annual anniversary of the date of the grant
and on the three subsequent annual anniversaries. Vesting typically is subject
to acceleration upon the occurrence of certain events, such as a change of
control of the Company, and in certain cases coupled with the termination, or
effective termination, of the executive's employment. The options generally
have an eight-year term. Prior to the adoption of the 1998 Stock Incentive
Plan, grants of options to the Company's employees, including the executive
officers, were made under two earlier plans. Options granted under those plans
were for a 10-year term, and generally were made on a 20% per year, five-year
vesting schedule. This vesting schedule likewise is subject to acceleration
upon the occurrence of certain events.

  Compensation of Chief Executive Officer. The Compensation Committee
establishes, and periodically adjusts, the base salary of Mr. Jaschke, who has
served as the Company's Chief Executive Officer since its formation in March
1996, with the objective of compensating him fairly based on his individual
efforts and the overall performance and success of the Company, while
maintaining the competitiveness of his base salary with salaries paid to
similarly situated chief executive officers. Typical of its policy with
respect to base salaries provided to employees generally, it has been the
Committee's intent to provide Mr. Jaschke with a level of stability and
certainty each year in the form of a base salary that is not tied specifically
to the achievement of established criteria, while payment of Mr. Jaschke's
annual performance bonus is determined based on the same annually determined
company-wide performance factors as those that apply to all of the Company's
employees. Mr. Jaschke's compensation, including his annual salary and option
levels, were evaluated and adjusted as part of the Compensation Committee's
overall evaluation of the Company's compensation policies and levels during
1999. As discussed above, performance-based bonuses for 1999 were to be paid
to the executive officers, including Mr. Jaschke, at 80% of the targeted
levels for 1999, and were to be paid in the form of the grant of stock options
during the first half of 2000 on the terms described above. Mr. Jaschke
received grants of options to purchase a total of 620,000 shares of the
Company's stock during 1999.

  Compensation Policy Regarding Deductibility. Section 162(m) of the Internal
Revenue Code, enacted in 1993, generally disallows a tax deduction to publicly
held companies for compensation exceeding $1 million paid to certain of the
company's executive officers. The limitation applies only to compensation that
is not considered to be performance-based. The non-performance based
compensation paid to the Company's executive officers in 1999 did not exceed
the $1 million limit per officer. The 1998 Stock Incentive Plan is structured
so that any compensation deemed paid to an executive officer in connection
with the exercise of option grants made under that plan will qualify as
performance-based compensation which is not subject to the $1 million
limitation.

                                      17
<PAGE>

The Compensation Committee limited the dollar amount of all other compensation
payable to the Company's executive officers to no more than $1 million. The
Compensation Committee is aware of the limitations imposed by Section 162(m),
and the exemptions available therefrom, and will address the issue of
deductibility when and if circumstances warrant and may use such exemptions in
addition to the exemption contemplated under the 1998 Stock Incentive Plan.

                                          Submitted by the Compensation
                                           Committee:

                                          Trygve E. Myhren
                                          Arthur L. Cahoon

Compensation Committee Interlocks and Insider Participation

  From January 1, 1999 through April 14, 1999, the Compensation Committee was
composed of Messrs. Allen and Myhren, as well as Stephen W. Schovee, who
served on the Board from the time of the Company's inception until his
resignation in January 1999. The membership of the Compensation Committee was
modified on April 15, 1999 to consist of Messrs. Myhren and Cahoon, as well as
George J. Still, Jr., who served in that capacity until his resignation in
October 1999. Mr. Myhren serves as the chairman of the Compensation Committee.
No member of this Committee is a present or former officer or employee of the
Company or any of its subsidiaries. No member of this Committee served on the
board of directors or compensation committee of any entity which has one or
more executive officers serving as a member of the Board or Compensation
Committee.

                CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Transactions with Directors and Executive Officers

  As a condition to the closing of the acquisition of Best Internet
Communications, Inc. (which does business as Hiway Technologies and which the
Company refers to as "Hiway"), which occurred on January 5, 1999, all related
party indebtedness was to be repaid to Hiway on or prior to closing. However,
the Company agreed to waive the condition that Arthur L. Cahoon repay his
indebtedness to Hiway in the principal amount of $280,409 with interest at the
then prime rate.

  The Company has invested a total of approximately $8.25 million in
convertible preferred stock of VIANet.Works, Inc. which represents
approximately 5.9% of the outstanding capital stock of VIANet.Works after the
recent completion of that company's IPO in February 2000. Mr. Halstedt, who
serves on the Company's Board of Directors, served as a member of
VIANet.Works' board of directors until September 1999, when he resigned from
that board. Mr. Hribar, who served on the Company's Board of Directors during
1999, also served on VIANet.Works' board until April 1999, when he resigned
from that board.

  Non-employee members of the Verio Board have received grants of options
under the Director Option Plan that would accelerate as to certain shares
subject to such options upon consummation of the Offer. See "Other Information
Concerning Current Directors--Directors' Compensation."

  Certain of the Company's executive officers have compensation arrangements
with the Company that will be affected by the consummation of the Offer. See
"Executive Compensation and Other Information Concerning Directors and
Officers--Compensation Protection Agreements and Subsequent Letter
Agreements."

Other Transactions

  On May 15, 1998, a U.S. subsidiary of NTT purchased 8,987,754 shares of
Common Stock (after giving effect to the Company's two for one stock split on
August 20, 1999) pursuant to a Stock Purchase and Master

                                      18
<PAGE>

Strategic Relationship Agreement dated as of April 7, 1998 (the "Stock
Purchase Agreement") between Verio and NTT (the "Stock Purchase"). The
aggregate purchase price paid by NTT for the shares was $99,999,997.94.

  Concurrently with the execution of the Stock Purchase Agreement, the Company
and a subsidiary of NTT entered into an Outside Service Provider Agreement
dated as of April 7, 1998 (the "OSP Agreement"). The OSP Agreement became
effective upon consummation of the Stock Purchase. The OSP Agreement provided
general terms on which Verio was designated as the preferred provider of
Internet access and related services to customers of NTT America, Inc. ("NTT
America") on a reseller basis. In addition Verio and NTT America agreed to
connect their backbones and establish a peering and transit relationship, and
that Verio would provide NTT America with full back-office and engineering
support. NTT America agreed to pay Verio for Verio's services at predetermined
rates reflective of the strategic relationship between the parties, under
which NTT America is entitled to "most favored customer" status and pricing
concessions. In furtherance of the OSP Agreement, Verio and a subsidiary of
NTT America subsequently executed a Strategic Partner Services Agreement on
October 26, 1998 which set out the specific terms and conditions pursuant to
which the OSP Agreement would be implemented (see below).

  Concurrently with their execution of the Stock Purchase Agreement, the
Company and NTT entered into an Investment Agreement dated as of April 7, 1998
(the "Investment Agreement"), NTT's rights under which were subsequently
assigned to its U.S. subsidiary that owns shares of Common Stock. The
Investment Agreement provides that, from and after November 15, 1998, NTT and
its affiliates could acquire voting securities of the Company through open
market and privately negotiated purchases or otherwise, if, and only to the
extent that, after the acquisition thereof NTT and its affiliates collectively
would beneficially own in the aggregate no more than 17.5% (the "Percentage
Limitation") of the shares of Common Stock calculated on a fully diluted
basis. At all times prior to the termination of the Standstill Restrictions
(as defined below), NTT is required to give the Company written notice of the
intention of NTT or any of its affiliates to purchase additional securities of
Verio at least two business days prior to the date NTT or any such affiliate
purchases or agrees to purchase any such securities.

  The Investment Agreement provides that, during the period commencing on
April 7, 1998 and ending on May 15, 2003 except as (a) specifically permitted
by the Investment Agreement or (b) specifically requested in writing in
advance by the Company upon the approval of the Board (without any prior
solicitation or request (or other act encouraging the delivery of such a
writing) having been made to the Company or to the Board or otherwise having
been publicly made), NTT will not, and will ensure that its affiliates do not,
in any manner, directly or indirectly, take any of the following actions
(collectively, the "Standstill Restrictions"): (i) acquire, or offer or agree
to acquire, or make any proposal or indicate any interest with respect to the
acquisition of, directly or indirectly, by purchase or otherwise, any material
amount of the assets or property of, any amounts of the voting securities of,
or any material amounts of the securities (other than voting securities) of
the Company or any of its affiliates controlled by the Company, (ii) solicit
proxies or consents or become a "participant" in a "solicitation" (as such
terms are defined or used in Regulation 14A under the Exchange Act) of proxies
or consents with respect to any voting securities of Verio or any of its
successors or controlled affiliates, or initiate or become a participant in
any stockholder proposal or "election contest" (as such term is defined or
used in Rule 14a-11 under the Exchange Act) with respect to the Company or any
of its successors or controlled affiliates or induce others to initiate the
same, or otherwise seek to advise or influence any person with respect to the
voting of any voting securities of the Company or any of its successors or
controlled affiliates; (iii) take any action for the purpose of calling a
stockholders' meeting of the Company or any of its successors or controlled
affiliates; (iv) make any proposal or any public announcement relating to, or
submit to the Company or any of its directors, officers, representatives,
trustees, employees, attorneys, advisors, agents or affiliates any proposal
for, a tender or exchange offer for voting securities of the Company or any of
its successors or controlled affiliates, the acquisition of voting securities
of the Company that would result in NTT (together with its affiliates)
exceeding the Percentage Limitation or a merger, business combination, sale of
assets, liquidation, restructuring, recapitalization or other extraordinary
corporate transaction relating to the Company or any of its

                                      19
<PAGE>

successors or controlled affiliates (other than with respect to joint
ventures, licenses, transactions contemplated by the OSP Agreement or other
transactions in the ordinary course of business) or take any action that might
require the Company or any of its successors or controlled affiliates to make
any public announcement regarding any of the foregoing; (v) deposit voting
securities of the Company or any of its successors or controlled affiliates
held by it into a voting trust or subject any such securities to voting
agreements, or grant any proxy with respect to any such securities to any
person not designated by the Company; (vi) form, join or in any way
participate in a "group" (within the meaning of Section 13(d)(3) of the
Exchange Act) for the purpose of acquiring, holding, voting or disposing of
voting securities of the Company or any of its successors or controlled
affiliates or taking any other actions restricted or prohibited under (i)
through (v) above; (vii) disclose to any person any intention, plan or
arrangement inconsistent with the foregoing; (viii) advise, assist or
encourage any other person in connection with any of the foregoing; (ix) enter
into any discussions, negotiations, arrangements or understandings with any
other person with respect to, or aid, abet or encourage any action prohibited
by, any of the foregoing, (x) make (publicly or to the Company or any of its
directors, officers, representatives, trustees, employees, attorneys,
advisors, agents, affiliates or security holders, directly or indirectly) any
request or proposal to amend, waive or terminate any of the Standstill
Restrictions or related provisions or any inquiry or statement relating
thereto; or (xi) act, alone or in concert with others, to seek to control or
influence in any material respect the management or policies of the Company.

  The Investment Agreement provides that, notwithstanding the Standstill
Restrictions, in the event (i) the Company publicly announces or invites any
person other than NTT to make a proposal, or elects to enter into
negotiations, with respect to, or (ii) the Board adopts a plan or program
regarding (whether or not publicly announced) any merger, consolidation or
other business combination, liquidation or recapitalization of the Company, or
any sale or transfer of all or substantially all of the assets of the Company
or any sale or transfer of voting securities of the Company that, if
consummated, would constitute a "change of control" (as defined in the
Investment Agreement) of the Company, then NTT and its affiliates will be
permitted to participate in any such process on terms that are substantially
comparable to those made available to any other participant in such process.

  The Investment Agreement provides that the Standstill Restrictions will
lapse and have no further force or effect (i) in the event of any agreement
between the Company and any other person or group pursuant to which, if
consummated, a change of control of the Company would occur (any such event
being an "Acquisition Event") or (ii) in the event any person or group shall
commence a tender offer or exchange offer which, if successful, would result
in a change of control (a "Third Party Offer"), and the bidder has financing
or financial commitments from responsible financial institutions sufficient to
finance the cash portion of such Third Party Offer, provided that in the event
that the transactions contemplated in connection with the Acquisition Event
are not completed or the Third Party Offer is not completed, all Standstill
Restrictions will be reinstated upon two business days' written notice to NTT
and will remain effective until subsequently terminated pursuant to the
Investment Agreement. NTT and its affiliates will be entitled to retain any
equity securities of Verio purchased by them following such termination but
prior to such reinstatement, provided that such equity securities and all
subsequent acquisitions of securities of the Company by NTT or any of its
affiliates will be subject to all of the provisions of the Investment
Agreement.

  Pursuant to the Investment Agreement, NTT may not, and is required to ensure
that its affiliates do not, transfer any equity securities of the Company
while there is pending, or otherwise transfer any such equity securities in
contemplation of, any Acquisition Proposal, unless such Acquisition Proposal
has been recommended publicly by the Board to all of the Company's
stockholders; provided that if the Board has not publicly recommended against
such Acquisition Proposal within three months of the later of (i) the initial
public announcement thereof by the acquiror or (ii) the formal presentation of
such Acquisition Proposal to the Board, then such restrictions will lapse and
have no further force or effect; provided, further, that in the event such
Acquisition Proposal is not completed, all such restrictions will be
reinstated upon two business days' written notice to NTT and will remain
effective until subsequently terminated pursuant to the Investment Agreement.

                                      20
<PAGE>

  The Investment Agreement provides that at all times prior to the termination
or lapsing of the Standstill Restrictions, NTT will take all action as may be
required so that all voting securities of the Company owned by NTT and its
affiliates are voted (i) with respect to elections of members of the Board,
for the Board's nominees to the Board, and (ii) with respect to all other
matters to be voted on by stockholders, either (A) in accordance with the
recommendations of the Board, or (B) for or against any such matter in the
same proportion as the shares owned by all other stockholders (excluding NTT
and each of its affiliates that is a stockholder of the Company) are voted
with respect to such matters. NTT and all affiliates of NTT owning voting
securities of the Company are required to be present, in person or by proxy,
at all meetings of the stockholders of the Company so that all such securities
owned by NTT and any such affiliate may be counted for the purposes of
determining the presence of a quorum at such meetings.

  The Investment Agreement provides that, subject to specified exceptions,
neither NTT nor any of its affiliates may, directly or indirectly, sell,
pledge or otherwise dispose of any equity securities of the Company (except to
NTT or any affiliates of NTT) without first offering to sell all such equity
securities to the Company pursuant to a right of first offer or, in the case
of a Significant Transfer (as defined below), a right of first refusal. A
"Significant Transfer" is a proposed sale of equity securities to (i) any of
up to 15 persons that are, or that the Company reasonably believes are likely
to become, competitors of the Company in the business of providing access to
the Internet for business customers in the United States, as identified in a
list that may be updated or revised by the Company no more than semi-annually
upon notice to NTT, or (ii) any person that following such transfer would
(alone or collectively with all affiliates of such person) beneficially own
more than 10% of the outstanding Shares. The parties' obligations with respect
to such rights of first offer and first refusal are subject to compliance with
notice and closing requirements and other conditions, some of which vary with
the market price of equity securities of the Company subject to the proposed
transfer. Each transferee of the equity securities of the Company is required
to agree to be bound by the same transfer restrictions as NTT and its
affiliates if such transferee's beneficial ownership of equity securities of
the Company following the transfer exceeds 7.5% of the shares of Common Stock
calculated on a fully diluted basis. The Company's rights of first offer and
first refusal do not apply to any transfer of Common Stock or securities
convertible into, exchangeable for or exercisable for Common Stock in a public
distribution, in a transaction pursuant to Rule 144 under the Securities Act,
in certain other transactions effected on a nationally recognized securities
exchange or Nasdaq, in an Acquisition Transaction or in connection with a
pledge that satisfied specified requirements.

  Pursuant to the Investment Agreement, the Company became obligated to
appoint to the Board an individual designated by NTT. The designee is entitled
to serve as a member of the Board until the first annual stockholders meeting
following May 15, 2001 so long as NTT and its affiliates collectively own
beneficially either (i) at least 50% of the aggregate shares of Common Stock
purchased by NTT pursuant to the Stock Purchase Agreement (adjusted as
appropriate for any subsequent stock split or reverse stock split or other
similar action) or (ii) at least 5% of the shares of Common Stock of the
Company calculated on a fully diluted basis (the amount in clause (i) or (ii)
above, the "Ownership Threshold"). If at any time during such initial term NTT
and its affiliates collectively cease to own beneficially shares of Common
Stock at least equal to the Ownership Threshold, NTT will, upon the request of
the Company, be required to cause the designee to resign from the Board.
Following the expiration of the initial term of the designee, until such time
as NTT and its affiliates collectively no longer beneficially own shares at
least equal to the Ownership Threshold, the Company will be required to take
all corporate action necessary to nominate for election to the Board an
individual appointed by NTT and to recommend to the Company's stockholders
such nominee's election to the Board. Yukimasa Ito has served as a member of
the Board as NTT's designee since September 1998. Additionally, under the
Investment Agreement, NTT designated three individuals to be employed by Verio
in corporate development, technical and marketing positions to assist in
implementing and carrying out the commercial relationship between Verio and
NTT.

  The Investment Agreement provides that, until such time as NTT and its
affiliates collectively no longer beneficially own shares of Common Stock at
least equal to the Ownership Threshold, (i) NTT also has the right to appoint
an observer who will have observer rights at meetings of the Board and, under
specified circumstances, an observer who will have observer rights at meetings
of the executive committee of the Board and (ii) at the

                                      21
<PAGE>

request of NTT, under specified circumstances, the Company will cause to be
appointed to the executive committee of the Board the NTT designee appointed
to the Board or elected to the Board in accordance with the provisions
described in the immediately preceding paragraph. The Investment Agreement
provides that NTT may designate up to three employees (the "Designated
Employees") to be employed by Verio, who shall have suitable experience and be
reasonably satisfactory to Verio, until the earlier of the date (i) NTT and
its affiliates collectively cease to own beneficially shares at least equal to
the Ownership Threshold (but not earlier than May 15, 2001), or (ii) the OSP
Agreement terminates or expires. Three Designated Employees have been working
in Verio's headquarter offices since shortly after the completion of NTT's
initial investment in Verio in the corporate development, marketing and
engineering areas.

  The Investment Agreement provides that if requested by any underwriter of
the shares of Common Stock, in the case of any offering of securities of the
Company registered under the Securities Act, NTT will not, and will ensure
that its affiliates do not, directly or indirectly, sell, offer, pledge,
contract to sell, sell any option or contract to purchase, purchase any option
or contract to sell, grant any option, warrant or right to purchase, or
otherwise dispose of or transfer, or enter into any swap or other agreement or
any arrangement that transfers, in whole or in part, directly or indirectly,
the economic consequence of ownership in, any equity securities of the Company
held by it or them, during the period following the effective date of a
registration statement of the Company filed under the Securities Act equal to
90 days, except in either case for equity securities included in such
registration and provided that, if directors and officers of the Company
holding shares of Common Stock generally are subject to holdback restrictions
of shorter duration, such shorter periods will apply to NTT and its
affiliates.

  Under the Investment Agreement, NTT is entitled to three demand
registrations by the Company (a "Demand Registration") of the shares of Common
Stock held by it and all other equity securities acquired by NTT or any of its
affiliates, together with any securities issued or issuable by the Company in
respect of any such securities by way of a distribution or split or in
connection with certain other specified types of transactions (collectively,
the "Registrable Securities"), at any time after the first anniversary of the
Company's initial public offering (subject to a maximum of three Demand
Registrations in total). Such demand is required to be made (i) by holders of
a majority of the outstanding Registrable Securities with respect to at least
25% of the Registrable Securities purchased by NTT pursuant to the Stock
Purchase Agreement or (ii) with respect to Registrable Securities the
anticipated aggregate offering price of which, net of underwriting discounts
and commissions, is at least $25 million or (iii) if Verio is then eligible to
file a registration statement on Form S-3 under the Securities Act, by any
holder or holders of Registrable Securities with respect to Registrable
Securities with an anticipated aggregate offering price, net of underwriting
discounts and commissions, in excess of $15 million. Upon such request, the
Company is required to use its reasonable best efforts to register securities
held by the requesting holders and any other permitted holders who desire to
sell shares of Common Stock pursuant to such Demand Registration. In addition
the Investment Agreement provides that, after the first anniversary of the
Company's initial public offering and subject to certain limitations, holders
of Registrable Securities may request to participate in any registration of
shares of Common Stock by the Company under the Securities Act (other than on
Form S-4 or S-8 under the Securities Act or in a registration in which the
only shares of Common Stock being registered are issuable upon the conversion
of other securities) (each, a "Piggyback Registration"). The Company is
required to pay all registration expenses (other than underwriting discounts
and commissions, transfer and documentary stamp taxes, if any, and fees and
disbursements of counsel of the holders other than the Company) with respect
to all registered Demand Registrations and Piggyback Registrations. Under the
Investment Agreement, the Company is required to indemnify the selling
stockholders and other specified persons, and the selling stockholders are
required to indemnify the Company and other specified persons, against certain
liabilities, including liabilities under the Securities Act, in respect of any
registration statement covered by the Investment Agreement.

  NTT is permitted under the Investment Agreement to assign its registration
rights thereunder (but only with all related obligations) to any permitted
transferee to which it transfers no less than 20% of the Registrable
Securities purchased by NTT or any of its affiliates pursuant to the Stock
Purchase Agreement or as permitted by the Investment Agreement (determined on
an as-converted basis), subject to specified restrictions of the

                                      22
<PAGE>

Investment Agreement. Securities will no longer be considered Registrable
Securities when (i) a registration statement with respect to the sale of such
securities shall have become effective under the Securities Act and such
securities shall have been disposed of under such registration statement, (ii)
such securities shall have been transferred pursuant to rule 144, (iii) such
securities shall have been otherwise transferred or disposed of, and new
certificates therefor not bearing a legend restricting further transfer shall
have been delivered by the Company, and subsequent transfer or disposition of
such securities shall not require registration or qualification under the
Securities Act or any similar state law then in force or (iv) such securities
shall have ceased to be outstanding. In addition, the right of any holder of
Registrable Securities to exercise the foregoing registration rights will
terminate at such time as all Registrable Securities held or entitled to be
held upon conversion by such holder may immediately be sold during any 90-day
period pursuant to rule 144 under the Securities Act or any similar rule or
regulation.

  On October 26, 1998, the Company and a subsidiary of NTT Communications
entered into a Strategic Partner Services Agreement setting forth the details
for implementation of the specific technical and administrative aspects of the
OSP Agreement and generally further refining the terms of the OSP Agreement.
The Company agreed to charge the NTT Communications subsidiary prices for the
services resold under this agreement that are at least as favorable as those
the Company offers to any other strategic partner of the Company. The
agreement terminates on October 26, 2001. In 1998, Verio billed approximately
$72,261.27 to the NTT Communications subsidiary pursuant to the agreement. In
1999, Verio billed approximately $1,681,741.55 to the NTT subsidiary and the
NTT Communications subsidiary billed Verio approximately $270,412.20 pursuant
to the agreement. In 2000, Verio billed approximately $937,043.63 to the NTT
Communications subsidiary through April 30, 2000 and the NTT Communications
subsidiary billed Verio approximately $270,412.20 through April 30, 2000
pursuant to the agreement.

  Pursuant to an agreement dated as of February 1, 1999, Verio and a
subsidiary of NTT agreed to cooperate to purchase certain equipment and
arrange for certain agents and certain architectural, engineering and
construction services related to improvements made to each of their facilities
located in the same buildings in New York, New York and San Jose, California.
Pursuant to this agreement, while no payments were made between the companies
in 1999, the NTT subsidiary paid to Verio approximately $1,758,827 between
February and early May 2000.

  In addition, as of September 22, 1999, Verio entered into a License
Agreement with NTT Communications, enabling NTT Communications to provide
Verio's Web hosting services to the Japanese market. Under the agreement, the
entire NTT group of companies is able to market Verio's Web hosting services
to businesses in Japan on a co-branded, "Powered by Verio" basis. Pursuant to
the agreement, NTT Communications paid a one-time, up front license fee
payment of $1.3 million at the time the agreement was signed and agreed to pay
ongoing monthly fees based on actual services sold. For 1999, the total amount
paid to Verio pursuant to the agreement was approximately $1,577,777.77 and
for 2000 the total amount billed by Verio through March 31, 2000 was
approximately $16,666.67. NTT Communications and Verio are continuing to work
together to develop NTT Communications' new data center in Tokyo, from which
Verio's web-hosting services will be offered by NTT Communications in Japan
beginning June 2000.

             SHARES AND OPTION AMOUNT WITH RESPECT TO THE COMPANY'S
                        DIRECTORS AND EXECUTIVE OFFICERS

Stock Options Granted in 1999

  The following table contains information concerning the grant of stock
options by the Company under the Company's stock option plans to the Named
Executive Officers in 1999. All stock options were granted at an exercise price
equal to the market price of the common stock on the last trading day before
the date of grant.

                                       24
<PAGE>

  The potential realizable value is calculated based on the fair market value
on the date of grant, which is equal to the exercise price of the options,
assuming that the stock appreciates in value from the date of grant,
compounded annually, until the end of the option term at the rate specified
(5% or 10%) and that the option is exercised and sold on the last day of the
option term for the appreciated stock price. Potential realizable value is net
of the option exercise price. The assumed rates of appreciation are specified
in the rules and regulations of the Securities and Exchange Commission and do
not represent the Company's estimate or projection of future stock price.
Actual gains, if any, resulting from stock option exercises and common stock
holdings are dependent on the future performance of the common stock and
overall stock market conditions. There can be no assurance that the amounts
reflected in this table will be achieved.

May 7, 2000

Board of Directors
Verio Inc.
8005 South Chester Street, Suite 200
Englewood, CO 80112

Members of the Board:

  You have requested our opinion as to the fairness, from a financial point of
view, to the holders of common stock, par value $.001 per share ("Company
Common Stock"), of Verio Inc. (the "Company"), and the holders of the
Company's 6.75% Series A Convertible Preferred Stock, liquidation preference
$50.00 per share ("Preferred Stock"), of the consideration to be received by
such holders pursuant to the Agreement and Plan of Merger, dated as of May 7,
2000 (the "Merger Agreement"), among NTT Communications Corporation
("Parent"), Chaser Acquisition, Inc. ("Sub"), a wholly owned subsidiary of
Parent, and the Company. Each share of Preferred Stock is currently
convertible into 1.0356 shares of Company Common Stock. Pursuant to the Merger
Agreement, Sub will make an offer (the "Offer") to purchase all of the issued
and outstanding shares of Company Common Stock at a price per share of $60 and
any and all of the issued and outstanding shares of Preferred Stock at a price
per share of $62.136, including certain additional amounts in respect of
dividends in certain circumstances, in each case net to the seller in cash,
without interest thereon. Pursuant to the Merger Agreement, following the
consummation of the Offer, Sub will be merged (the "Merger") with and into the
Company. In the Merger, each issued and outstanding share of Company Common
Stock and Preferred Stock (other than shares owned directly or indirectly by
Parent or the Company and any shares the subject of appraisal rights) will be
converted into the right to receive the price per share of Company Common
Stock or Preferred Stock, as applicable, paid in the Offer.

  In connection with rendering our opinion, we have reviewed certain publicly
available information concerning the Company and certain other financial
information concerning the Company that were provided to us by the Company. We
have discussed the past and current business operations, financial condition
and prospects of the Company with certain officers and employees of the
Company. With the Company's consent, we did not review the Company's financial
forecasts for the Company. Subject to the foregoing, we have also considered
such other information, financial studies, analyses, investigations and
financial, economic and market criteria that we deemed relevant.

  In our review and analysis and in arriving at our opinion, we have assumed
and relied upon the accuracy and completeness of the information reviewed by
us for the purpose of this opinion and we have not assumed any responsibility
for independent verification of such information. Without limiting the
generality of the foregoing, we have relied on advice from the Company
regarding the conversion price adjustment and voting provisions of the terms
of the Preferred Stock in the event of a merger involving the Company. We have
not assumed any responsibility for any independent evaluation or appraisal of
any of the assets (including properties and facilities) or liabilities of the
Company.

  Our opinion is necessarily based upon conditions as they exist and can be
evaluated on the date hereof. Our opinion does not address the Company's
underlying business decision to enter into the Merger or the Merger Agreement,
and we express no view on the effect on the Company of the Offer, the Merger
and related transactions. Our opinion is directed only to the fairness, from a
financial point of view, of the consideration to

SALOMON SMITH BARNEY INC. 388 Greenwich Street, New York, NY 10013

                                       1
<PAGE>

be received in the Offer and the Merger by holders of Company Common Stock and
Preferred Stock. Our opinion does not address the fairness of the allocation
between the Company Common Stock and the Preferred Stock of the aggregate
merger consideration to be paid in the transactions. Our opinion does not
constitute a recommendation concerning (i) whether holders of Company Common
Stock or Preferred Stock should accept the Offer, (ii) how holders of Company
Common Stock should vote with respect to the Merger Agreement or the Merger or
(iii) whether holders of Company Common Stock or Preferred Stock should
exercise appraisal rights in connection with the Merger.

  We have acted as financial advisor to the Board of Directors of the Company
in connection with the Merger and will receive a fee for our services, a
significant portion of which is contingent upon consummation of the Merger. In
the ordinary course of business, we and our affiliates may actively trade the
securities of the Company and Parent for our own account and for the accounts
of customers and, accordingly, may at any time hold a long or short position
in such securities. In addition, we and our affiliates have previously
rendered certain investment banking and financial advisory services to the
Company and Parent for which we have received customary compensation. We and
our affiliates (including Citigroup Inc.) may have other business
relationships with the Company or Parent in the ordinary course of their
businesses.

  Based upon and subject to the foregoing, it is our opinion that (a) as of
the date hereof, the consideration to be received in the Offer and the Merger,
taken together, by holders of Company Common Stock is fair to such holders
(other than Parent) from a financial point of view and (b) as of the date
hereof, the consideration to be received in the Offer and the Merger, taken
together, by holders of Preferred Stock is fair to such holders from a
financial point of view.

                                          Very truly yours,

                                          SALOMON SMITH BARNEY INC.

                                 May 17, 2000

Dear Stockholder:

  I am pleased to inform you that on May 7, 2000, Verio Inc. ("Verio") entered
into an Agreement and Plan of Merger (the "Merger Agreement") with NTT
Communications Corporation ("NTT Communications"), a wholly-owned subsidiary
of Nippon Telegraph and Telephone Corporation ("NTT"), and its wholly-owned
subsidiary, Chaser Acquisition, Inc. (the "Purchaser"), that provides for the
acquisition of Verio by NTT Communications through the Purchaser at a price of
$60.00 per share of Verio's Common Stock ("Common Stock") (other than shares
of Common Stock already owned by NTT Communications and its subsidiaries) and
$62.136 per share of Verio's Series A 6.75% Convertible Preferred Stock
("Preferred Stock").

  Under the terms of the Merger Agreement, the Purchaser has commenced today a
cash tender offer to purchase all Common Stock (other than shares already
owned by NTT Communications and its subsidiaries) at a price of $60.00 per
share and all Preferred Stock at a price of $62.136 per share, plus, if the
purchase of the shares of Preferred Stock pursuant to the tender offer occurs
after July 31, 2000, accumulated and unpaid dividends on each share of
Preferred Stock, net to tendering stockholders in cash, without interest. The
tender offer is currently scheduled to expire at 12:00 o'clock midnight New
York time on Wednesday, June 14, 2000.

  Following the successful completion of the tender offer, the Purchaser will
be merged into Verio and all shares not purchased in the tender offer (other
than shares held by dissenting stockholders, if applicable) will be converted
into the right to receive in cash the same price per share as paid in the
tender offer, without interest.

  Your Board of Directors has unanimously (with the exception of the designee
of NTT Communications on the Board) approved the Merger Agreement, the tender
offer, and the merger and has determined that the terms of the tender offer
and the merger are fair to and in the best interests of holders of Verio's
Common Stock and Preferred Stock. Accordingly, the Board of Directors
recommends that you accept the tender offer and tender your Verio stock to the
Purchaser pursuant to the tender offer.

  In arriving at its recommendation, the Board of Directors gave careful
consideration to a number of factors that are described in the enclosed
Schedule 14D-9, including, among other things, the opinion of Salomon Smith
Barney Inc. that the consideration to be received in the tender offer and the
merger, taken together, is fair to holders of Common Stock and Preferred Stock
from a financial point of view as of the date of such opinion.

  Also accompanying this letter is a copy of the Purchaser's Offer to Purchase
and related materials, including a letter of transmittal for use in tendering
your shares. These documents set forth the terms and conditions of the
Purchaser's tender offer and provide instructions as to how to tender your
shares. We urge you to read each of the enclosed materials carefully.

  On behalf of the Board of Directors,

                                          Very truly yours,
                                          Justin L. Jaschke

Justin L. Jaschke
Chief Executive Officer

Greenwood Village, CO 80011

Dear Mr. Jaschke:

          As you know, Verio Inc. ("Verio") is entering into the Agreement and
Plan of Merger among NTT Communications Corporation, Chaser Acquisition, Inc.
("Acquisition Sub") and Verio Inc. dated as of May 7, 2000 (the "Merger
Agreement") pursuant to which it is anticipated that Acquisition Sub will
acquire all the outstanding capital stock of Verio.  As you also know, Verio has
offered to continue your current employment after the consummation of the Offer
and the Merger (both as defined in the Merger Agreement).  Therefore, in
consideration of such continued employment and the mutual covenants and
agreements contained herein, Verio and you agree as follows:

             reduction applicable to Protected Officer is comparable to the
             reduction applied to other senior executives of the Company."

          3.  Subsection (viii) of Section 2.8(a) of the Protection Agreement is
amended in its entirety to read as follows:

             "(viii)  the failure of the Company to obtain an agreement,

             Agreement, as contemplated by Section 11.1 hereof, provided,

             contained herein to the contrary, neither (i) any change in the
             Protected Officer's position or responsibilities that results
             primarily from the change in the status of the Company from a
             company the common stock of which is registered under the
             Securities Act of 1934 and traded on a national securities exchange
             or the NASDAQ National Market to a subsidiary of NTT, nor (ii) any
             change in the Protected Officer's amount or level of participation
             in the retention and incentive plan referred to in Section 6.14(a)
             of the Merger Agreement, as compared to the amount or level of
             participation in incentive plans of Verio prior to consummation of
             the transactions contemplated by the Merger Agreement, shall by
             itself or in combination with any other event or events constitute
             Good Reason."

          5.  Subsection (iv) of Section 4.1(b) of the Protection Agreement is
amended in its entirety to read as follows:

             "(iv)  the restrictions on any outstanding incentive awards

             units) granted prior to the execution of the Merger Agreement to
             Protected Officer under the Company's stock option and other stock
             incentive plans or under any other incentive plan or arrangement
             shall lapse and such incentive award shall become 100% vested, all
             stock options and stock appreciation rights granted prior to the
             execution of the Merger Agreement to Protected Officer shall become
             immediately exercisable and shall become 100% vested and all
             performance units granted prior to the execution of the Merger
             Agreement shall become 100% vested."

          6.  If you are employed by Verio:

             (i)  thirteen months after the date the Offer (as defined in the
             Merger Agreement) is consummated and have been continuously
             employed by Verio since the date of this letter agreement, Verio
             will pay to you an amount equal to one-half of the Employment Bonus
             (as defined below); and

             (ii)  twenty-five months after the date the Offer (as defined in
             the Merger Agreement) is consummated and have then been
             continuously employed by Verio since the date of this letter
             agreement, Verio will pay to you the remainder of the Employment
             Bonus.

          You acknowledge and agree that any amounts that may become payable to
you (or your successors) pursuant to the grants made as of the Effective Time
(as defined in the Merger Agreement) under the retention and incentive plans
adopted by Verio pursuant to Section 6.14(a) of the Merger Agreement shall be
reduced by the amounts paid to you pursuant to this paragraph 6.

          For purposes of this paragraph 6, the "Employment Bonus" shall mean
(a) three times the sum of:

             (i)  the amount of your annual base salary in effect immediately
             prior to the consummation of the Offer (as defined in the Merger
             Agreement), including all amounts of your annual base salary that
             are then deferred under the qualified and non-qualified employee
             benefit plans of Verio or any other agreement or arrangement; and

             (ii)  the greater of (i) 100% of the last annual incentive payment
             paid or payable to you prior to the consummation of the Offer (as
             defined in the Merger Agreement) under Verio's

                                       4
<PAGE>

             cash bonus incentive plan; and (ii) your incentive target for the
             fiscal year in which such Offer is consummated.

          7.  You acknowledge and agree that your continued employment by Verio
after consummation of the Offer (as defined in the Merger Agreement) and your
participation in Verio's incentive and retention programs thereafter shall be
subject to your execution prior to consummation of the Offer of (i) an agreement
to remain employed by Verio immediately after the consummation of the Offer,
(ii) a written covenant not to compete with or solicit employees of Verio and
its affiliates in the United States for a period ending at the later of two
years following the consummation of the Offer and one year after termination of
employment and (iii) an agreement to maintain the confidentiality of
confidential information and data of Verio and its affiliates, each in a form
reasonably satisfactory to NTT and Verio.

          8.  You acknowledge and agree that prior to consummation of the Offer
you will enter into a Stock Option Deferral Agreement substantially in the form
attached hereto as Exhibit A with respect to each "Company Stock Option" (as
defined in the Merger Agreement) held by  you that waives acceleration and
defers vesting of 20% of the unvested options held by you that would otherwise
automatically become vested immediately prior to consummation of the Offer.

          9.  This letter agreement (and the amendments to the Protection
Agreement contained herein) shall cease to be effective upon the termination of
the Merger Agreement pursuant to its terms.

          10.  Nothing in this letter agreement entitles you to be employed by
Verio for any specific period of time or otherwise interferes with your status
as an employee at will of Verio.

             contained herein to the contrary, neither (x) any change in the
             Protected Officer's position or responsibilities shall include any
             such change that results primarily from the change in the status of
             the Company from a company the common stock of which is registered
             under the Securities Act of 1934 and traded on a national
             securities exchange to a subsidiary of NTT, nor (y) any change in

             retention and incentive plan referred to in Section 6.14(a) of the
             Merger Agreement, as compared to the amount or level of
             participation in incentive plans of Verio prior to

             consummation of the transactions contemplated by the Merger
             Agreement, shall by itself or in combination with any other event

          (g)  As used herein, "Cause" means the termination of the Optionee's
                                -----
          Continuous Status as an Employee for "Cause" as such term is defined
          in the Optionee's employment agreement, or in the absence of such

          (i) acts in bad faith and to the detriment of the Company; (ii)
          refuses or fails to act in substantial accordance with any material
          direction or order of the Company; (iii) exhibits in regard to his

          6.  All other provisions of the Option Agreement shall remain in full
force and effect.

          7.  (a) If the Optionee is employed by Verio or its affiliates
thirteen (13) months after the date of the Offer (as defined in the Merger
Agreement) and has been continuously so employed since such date, then Verio

on such date.

          (c)  If the Optionee's Continuous Status as an Employee is terminated
by the Company or Related Entity, as the case may be, voluntarily by the
Optionee with Good Reason (as defined above) within twenty-five (25) months of
the Corporate Transaction described in the Merger Agreement, then a pro rata
                                                                    --------
portion of the unpaid amount of the bonus payable under clause (a) and/or (b)

payable.

contained herein) shall become effective immediately before the consummation of

          9.  Nothing in this Agreement entitles you to be employed by Verio for
any specific period of time or otherwise interferes with your status as an
employee at will of Verio.

          IN WITNESS WHEREOF, the parties hereto have executed this Agreement on

Sean G. Brophy
VP Corporate Development

Englewood, CO 80110

Dear Mr. Brophy:

          As you know, Verio Inc. ("Verio") is entering into the Agreement and
Plan of Merger among NTT Communications Corporation, Chaser Acquisition, Inc.
("Acquisition Sub") and Verio Inc. dated as of May 7, 2000 (the "Merger
Agreement") pursuant to which it is anticipated that Acquisition Sub will
acquire all the outstanding capital stock of Verio.  As you also know, Verio has
offered to continue your current employment after the consummation of the Offer
and the Merger (both as defined in the Merger Agreement).  Therefore, in
consideration of such continued employment and the mutual covenants and
agreements contained herein, Verio and you agree as follows:

          1.  Effective immediately after consummation of the Offer (as defined
in the Merger Agreement), Section 2.5 of the Compensation Protection Agreement
between Verio and you dated April 1, 1998, (the "Protection Agreement") is
amended by adding the following new subsection (f) immediately following
subsection (e) appearing therein:

             "(f) Notwithstanding anything contained in this Agreement to the
             contrary, no acquisition of the Company's voting securities by, nor
             any merger, consolidation or reorganization of the Company with,
             any entity (or entities) that directly or indirectly is controlled
             by or is under common control with the NTT Communications
             Corporation shall constitute a Change in Control."

          2.  Subsections (i) through (iv) of Section 2.8(a) of the Protection
Agreement are amended in their entirety to read as follows:

             "(i)  (A) a change in Protected Officer's title, position or
             responsibilities (including reporting responsibilities) which
             represent a material adverse change from Protected Officer's title,
             position or responsibilities as in effect at the execution of the
             Agreement and Plan of Merger dated as of May 7, 2000
<PAGE>

             (the "Merger Agreement") among NTT Communications Corporation
             ("NTT"), Chaser Acquisition Inc., and the Company; (B) the
             assignment to Protected Officer of any material duties or
             responsibilities which are significantly inconsistent with
             Protected Officer's title, position or responsibilities as in
             effect at the execution of the Merger Agreement; or (C) any removal
             of Protected Officer from or failure to reappoint or reelect
             Protected Officer to any of such offices or positions, except in
             connection with the termination of Protected Officer's employment
             for Disability, Cause, as a result of Protected Officer's death or
             by Protected Officer other than for Good Reason;

             (ii)  reduction in Protected Officer's base salary to a level below
             that in effect at the execution of the Merger Agreement (except to
             the extent such reduction is part of a comprehensive reduction in
             salary applicable to employees of the Company generally so long as
             the reduction applicable to Protected Officer is comparable to the
             reduction applied to other senior executives of the Company), or
             any failure to pay Protected Officer any compensation or benefits
             to which Protected Officer is entitled within five (5) days of the
             date due other than an inadvertent failure, administrative error or
             on account of events beyond the control of the Company;

             (iii)  the Company's requiring Protected Officer to be based at any
             place outside the farther of a 50-mile radius Protected Officer's
             job location and a 50-mile radius of the Protected Officer's
             residence prior to the execution of the Merger Agreement, except
             for reasonably required travel on the Company's business which is
             not materially greater than such travel requirements prior to the
             execution of the Merger Agreement, determined without regard to
             travel to meet with representatives of Parent (as defined in the
             Merger Agreement); or

             (iv)  the failure by the Company to provide Protected Officer with
             compensation and benefits (other than any compensation or benefits
             under any stock option, stock purchase or other compensation or
             benefit plans, programs or practices payable in or measured by the
             value of the Company's common stock) in the aggregate, not
             significantly less (in terms of benefit levels and/or reward
             opportunities) to those provided under the employee benefit plans,
             programs and practices, including,

                                       2

             but not limited to, the plans listed on Appendix A, in which
             Protected Officer was participating at the execution of the Merger
             Agreement or which are provided to other similarly situated
             executives of the Company, except to the extent such failure is
             part of a comprehensive reduction in compensation or benefits
             applicable to employees of the Company generally so long as the
             reduction applicable to Protected Officer is comparable to the
             reduction applied to other senior executives of the Company."

          3.  Subsection (viii) of Section 2.8(a) of the Protection Agreement is
amended in its entirety to read as follows:

             "(viii)  the failure of the Company to obtain an agreement,
             satisfactory to Protected Officer, from any Successors and Assigns
             (as hereinafter defined) to assume and agree to perform this
             Agreement, as contemplated by Section 11.1 hereof, provided,
                                                                --------
             however, that Good Reason shall not include a failure by NTT or any
             -------
             of its affiliates to assume and perform this Agreement in
             connection with the Merger."

          4.  The following new Section 2.8(d) is added immediately after
Section 2.8(c) of the Protection Agreement:

             "(d)  For purposes of this Agreement, notwithstanding anything
             contained herein to the contrary, neither (i) any change in the
             Protected Officer's position or responsibilities that results
             primarily from the change in the status of the Company from a
             company the common stock of which is registered under the
             Securities Act of 1934 and traded on a national securities exchange
             or the NASDAQ National Market to a subsidiary of NTT, nor (ii) any
             change in the Protected Officer's amount or level of participation
             in the retention and incentive plan referred to in Section 6.14(a)
             of the Merger Agreement, as compared to the amount or level of
             participation in incentive plans of Verio prior to consummation of
             the transactions contemplated by the Merger Agreement, shall by
             itself or in combination with any other event or events constitute
             Good Reason."

          5.  Subsection (iv) of Section 4.1(b) of the Protection Agreement is
amended in its entirety to read as follows:

             "(iv)  the restrictions on any outstanding incentive awards
             (including restricted stock and granted performance shares or

                                       3
<PAGE>

             units) granted prior to the execution of the Merger Agreement to
             Protected Officer under the Company's stock option and other stock
             incentive plans or under any other incentive plan or arrangement
             shall lapse and such incentive award shall become 100% vested, all
             stock options and stock appreciation rights granted prior to the
             execution of the Merger Agreement to Protected Officer shall become
             immediately exercisable and shall become 100% vested and all
             performance units granted prior to the execution of the Merger
             Agreement shall become 100% vested."

          6.  If you are employed by Verio:

             (i)  thirteen months after the date the Offer (as defined in the
             Merger Agreement) is consummated and have been continuously
             employed by Verio since the date of this letter agreement, Verio
             will pay to you an amount equal to one-half of the Employment Bonus
             (as defined below); and

             (ii)  twenty-five months after the date the Offer (as defined in
             the Merger Agreement) is consummated and have then been
             continuously employed by Verio since the date of this letter
             agreement, Verio will pay to you the remainder of the Employment
             Bonus.

          You acknowledge and agree that any amounts that may become payable to
you (or your successors) pursuant to the grants made as of the Effective Time
(as defined in the Merger Agreement) under the retention and incentive plans
adopted by Verio pursuant to Section 6.14(a) of the Merger Agreement shall be
reduced by the amounts paid to you pursuant to this paragraph 6.

          For purposes of this paragraph 6, the "Employment Bonus" shall mean
(a) two times the sum of:

             (i)  the amount of your annual base salary in effect immediately
             prior to the consummation of the Offer (as defined in the Merger
             Agreement), including all amounts of your annual base salary that
             are then deferred under the qualified and non-qualified employee
             benefit plans of Verio or any other agreement or arrangement; and

             (ii)  the greater of (i) 100% of the last annual incentive payment
             paid or payable to you prior to the consummation of the Offer (as
             defined in the Merger Agreement) under Verio's

                                       4

             cash bonus incentive plan; and (ii) your incentive target for the
             fiscal year in which such Offer is consummated.

          7.  You acknowledge and agree that your continued employment by Verio
after consummation of the Offer (as defined in the Merger Agreement) and your
participation in Verio's incentive and retention programs thereafter shall be
subject to your execution prior to consummation of the Offer of (i) an agreement
to remain employed by Verio immediately after the consummation of the Offer,
(ii) a written covenant not to compete with or solicit employees of Verio and
its affiliates in the United States for a period ending at the later of two
years following the consummation of the Offer and one year after termination of
employment and (iii) an agreement to maintain the confidentiality of
confidential information and data of Verio and its affiliates, each in a form
reasonably satisfactory to NTT and Verio.

          8.  You acknowledge and agree that prior to consummation of the Offer
you will enter into a Stock Option Deferral Agreement substantially in the form
attached hereto as Exhibit A with respect to each "Company Stock Option" (as
defined in the Merger Agreement) held by  you that waives acceleration and
defers vesting of 20% of the unvested options held by you that would otherwise
automatically become vested immediately prior to consummation of the Offer.

          9.  This letter agreement (and the amendments to the Protection
Agreement contained herein) shall cease to be effective upon the termination of
the Merger Agreement pursuant to its terms.

          10.  Nothing in this letter agreement entitles you to be employed by
Verio for any specific period of time or otherwise interferes with your status
as an employee at will of Verio.

               -------
               any of its affiliates to assume and perform this Agreement; or

             (ix)  For purposes of this Agreement, notwithstanding anything
             contained herein to the contrary, neither (x) any change in the
             Protected Officer's position or responsibilities shall include any
             such change that results primarily from the change in the status of
             the Company from a company the common stock of which is registered
             under the Securities Act of 1934 and traded on a national
             securities exchange to a subsidiary of NTT, nor (y) any change in

             retention and incentive plan referred to in Section 6.14(a) of the
             Merger Agreement, as compared to the amount or level of

          Continuous Status as an Employee for "Cause" as such term is defined
          in the Optionee's employment agreement, or in the absence of such
          definition, then as in the determination of the Company, the Optionee:
          (i) acts in bad faith and to the detriment of the Company; (ii)
          refuses or fails to act in substantial accordance with any material
          direction or order of the Company; (iii) exhibits in regard to his

                                                                    --------

Dear Mr. DeMarche:

          As you know, Verio Inc. ("Verio") is entering into the Agreement and
Plan of Merger among NTT Communications Corporation, Chaser Acquisition, Inc.
("Acquisition Sub") and Verio Inc. dated as of May 7, 2000 (the "Merger
Agreement") pursuant to which it is anticipated that Acquisition Sub will
acquire all the outstanding capital stock of Verio.  As you also know, Verio has
offered to continue your current employment after the consummation of the Offer
and the Merger (both as defined in the Merger Agreement).  Therefore, in
consideration of such continued employment and the mutual covenants and
agreements contained herein, Verio and you agree as follows:

          1. Effective immediately after consummation of the Offer (as defined
in the Merger Agreement), Section 2.5 of the Compensation Protection Agreement
between Verio and you dated April 1, 1998, (the "Protection Agreement") is
amended by adding the following new subsection (f) immediately following
subsection (e) appearing therein:

             "(f) Notwithstanding anything contained in this Agreement to the
             contrary, no acquisition of the Company's voting securities by, nor
             any merger, consolidation or reorganization of the Company with,
             any entity (or entities) that directly or indirectly is controlled
             by or is under common control with the NTT Communications
             Corporation shall constitute a Change in Control."

          2.  Subsections (i) through (iv) of Section 2.8(a) of the Protection
Agreement are amended in their entirety to read as follows:

             "(i)  (A) a change in Protected Officer's title, position or
             responsibilities (including reporting responsibilities) which
             represent a material adverse change from Protected Officer's title,
             position or responsibilities as in effect at the execution of the
             Agreement and Plan of Merger dated as of May 7, 2000

             effect at the execution of the Merger Agreement; or (C) any removal
             of Protected Officer from or failure to reappoint or reelect

             for Disability, Cause, as a result of Protected Officer's death or
             by Protected Officer other than for Good Reason;

             (ii)  reduction in Protected Officer's base salary to a level below
             that in effect at the execution of the Merger Agreement (except to
             the extent such reduction is part of a comprehensive reduction in
             salary applicable to employees of the Company generally so long as
             the reduction applicable to Protected Officer is comparable to the
             reduction applied to other senior executives of the Company), or
             any failure to pay Protected Officer any compensation or benefits
             to which Protected Officer is entitled within five (5) days of the
             date due other than an inadvertent failure, administrative error or
             on account of events beyond the control of the Company;

             (iii)  the Company's requiring Protected Officer to be based at any

             (iv)  the failure by the Company to provide Protected Officer with
             compensation and benefits (other than any compensation or benefits
             under any stock option, stock purchase or other compensation or
             benefit plans, programs or practices payable in or measured by the
             value of the Company's common stock) in the aggregate, not

             Protected Officer was participating at the execution of the Merger
             Agreement or which are provided to other similarly situated

             part of a comprehensive reduction in compensation or benefits
             applicable to employees of the Company generally so long as the
             reduction applicable to Protected Officer is comparable to the
             reduction applied to other senior executives of the Company."

          3.  Subsection (viii) of Section 2.8(a) of the Protection Agreement is
amended in its entirety to read as follows:

             "(viii)  the failure of the Company to obtain an agreement,
             satisfactory to Protected Officer, from any Successors and Assigns
             (as hereinafter defined) to assume and agree to perform this
             Agreement, as contemplated by Section 11.1 hereof, provided,
                                                                --------
             however, that Good Reason shall not include a failure by NTT or any
             -------
             of its affiliates to assume and perform this Agreement in
             connection with the Merger."

          4.  The following new Section 2.8(d) is added immediately after
Section 2.8(c) of the Protection Agreement:

             "(d)  For purposes of this Agreement, notwithstanding anything
             contained herein to the contrary, neither (i) any change in the
             Protected Officer's position or responsibilities that results
             primarily from the change in the status of the Company from a
             company the common stock of which is registered under the
             Securities Act of 1934 and traded on a national securities exchange
             or the NASDAQ National Market to a subsidiary of NTT, nor (ii) any
             change in the Protected Officer's amount or level of participation
             in the retention and incentive plan referred to in Section 6.14(a)
             of the Merger Agreement, as compared to the amount or level of
             participation in incentive plans of Verio prior to consummation of
             the transactions contemplated by the Merger Agreement, shall by
             itself or in combination with any other event or events constitute
             Good Reason."

          5.  Subsection (iv) of Section 4.1(b) of the Protection Agreement is
amended in its entirety to read as follows:

             "(iv)  the restrictions on any outstanding incentive awards
             (including restricted stock and granted performance shares or

                                       3
<PAGE>

             units) granted prior to the execution of the Merger Agreement to
             Protected Officer under the Company's stock option and other stock
             incentive plans or under any other incentive plan or arrangement
             shall lapse and such incentive award shall become 100% vested, all
             stock options and stock appreciation rights granted prior to the
             execution of the Merger Agreement to Protected Officer shall become
             immediately exercisable and shall become 100% vested and all
             performance units granted prior to the execution of the Merger
             Agreement shall become 100% vested."

          6.  If you are employed by Verio:

             (i)  thirteen months after the date the Offer (as defined in the
             Merger Agreement) is consummated and have been continuously
             employed by Verio since the date of this letter agreement, Verio
             will pay to you an amount equal to one-half of the Employment Bonus
             (as defined below); and

             (ii)  twenty-five months after the date the Offer (as defined in
             the Merger Agreement) is consummated and have then been
             continuously employed by Verio since the date of this letter
             agreement, Verio will pay to you the remainder of the Employment
             Bonus.

          You acknowledge and agree that any amounts that may become payable to
you (or your successors) pursuant to the grants made as of the Effective Time
(as defined in the Merger Agreement) under the retention and incentive plans
adopted by Verio pursuant to Section 6.14(a) of the Merger Agreement shall be
reduced by the amounts paid to you pursuant to this paragraph 6.

          For purposes of this paragraph 6, the "Employment Bonus" shall mean
(a) two times the sum of:

             (i)  the amount of your annual base salary in effect immediately
             prior to the consummation of the Offer (as defined in the Merger
             Agreement), including all amounts of your annual base salary that
             are then deferred under the qualified and non-qualified employee
             benefit plans of Verio or any other agreement or arrangement; and

             (ii)  the greater of (i) 100% of the last annual incentive payment
             paid or payable to you prior to the consummation of the Offer (as
             defined in the Merger Agreement) under Verio's

             fiscal year in which such Offer is consummated.

          7.  You acknowledge and agree that your continued employment by Verio

participation in Verio's incentive and retention programs thereafter shall be
subject to your execution prior to consummation of the Offer of (i) an agreement
to remain employed by Verio immediately after the consummation of the Offer,
(ii) a written covenant not to compete with or solicit employees of Verio and
its affiliates in the United States for a period ending at the later of two
years following the consummation of the Offer and one year after termination of
employment and (iii) an agreement to maintain the confidentiality of
confidential information and data of Verio and its affiliates, each in a form
reasonably satisfactory to NTT and Verio.

          8.  You acknowledge and agree that prior to consummation of the Offer
you will enter into a Stock Option Deferral Agreement substantially in the form
attached hereto as Exhibit A with respect to each "Company Stock Option" (as
defined in the Merger Agreement) held by  you that waives acceleration and
defers vesting of 20% of the unvested options held by you that would otherwise
automatically become vested immediately prior to consummation of the Offer.

          9.  This letter agreement (and the amendments to the Protection
Agreement contained herein) shall cease to be effective upon the termination of
the Merger Agreement pursuant to its terms.

               however, that Good Reason shall not include a failure by NTT or
               -------
               any of its affiliates to assume and perform this Agreement; or

             (ix)  For purposes of this Agreement, notwithstanding anything
             contained herein to the contrary, neither (x) any change in the
             Protected Officer's position or responsibilities shall include any
             such change that results primarily from the change in the status of
             the Company from a company the common stock of which is registered
             under the Securities Act of 1934 and traded on a national
             securities exchange to a subsidiary of NTT, nor (y) any change in
             the Protected Officer's amount or level of participation in the
             retention and incentive plan referred to in Section 6.14(a) of the
             Merger Agreement, as compared to the amount or level of
             participation in incentive plans of Verio prior to

                                       10

             consummation of the transactions contemplated by the Merger
             Agreement, shall by itself or in combination with any other event

          Continuous Status as an Employee for "Cause" as such term is defined
          in the Optionee's employment agreement, or in the absence of such
          definition, then as in the determination of the Company, the Optionee:
          (i) acts in bad faith and to the detriment of the Company; (ii)
          refuses or fails to act in substantial accordance with any material
          direction or order of the Company; (iii) exhibits in regard to his

                                                                    --------

amended by adding the following new subsection (f) immediately following
subsection (e) appearing therein:

             "(f) Notwithstanding anything contained in this Agreement to the
             contrary, no acquisition of the Company's voting securities by, nor
             any merger, consolidation or reorganization of the Company with,
             any entity (or entities) that directly or indirectly is controlled
             by or is under common control with the NTT Communications
             Corporation shall constitute a Change in Control."

             represent a material adverse change from Protected Officer's title,

             primarily from the change in the status of the Company from a
             company the common stock of which is registered under the
             Securities Act of 1934 and traded on a national securities exchange
             or the NASDAQ National Market to a subsidiary of NTT, nor (ii) any
             change in the Protected Officer's amount or level of participation
             in the retention and incentive plan referred to in Section 6.14(a)
             of the Merger Agreement, as compared to the amount or level of
             participation in incentive plans of Verio prior to consummation of
             the transactions contemplated by the Merger Agreement, shall by
             itself or in combination with any other event or events constitute
             Good Reason."

          5.  Subsection (iv) of Section 4.1(b) of the Protection Agreement is
amended in its entirety to read as follows:

             "(iv)  the restrictions on any outstanding incentive awards
             (including restricted stock and granted performance shares or

             units) granted prior to the execution of the Merger Agreement to
             Protected Officer under the Company's stock option and other stock
             incentive plans or under any other incentive plan or arrangement
             shall lapse and such incentive award shall become 100% vested, all
             stock options and stock appreciation rights granted prior to the
             execution of the Merger Agreement to Protected Officer shall become
             immediately exercisable and shall become 100% vested and all
             performance units granted prior to the execution of the Merger
             Agreement shall become 100% vested."

          6.  If you are employed by Verio:

             (i)  thirteen months after the date the Offer (as defined in the
             Merger Agreement) is consummated and have been continuously
             employed by Verio since the date of this letter agreement, Verio
             will pay to you an amount equal to one-half of the Employment Bonus
             (as defined below); and

             (ii)  twenty-five months after the date the Offer (as defined in
             the Merger Agreement) is consummated and have then been
             continuously employed by Verio since the date of this letter
             agreement, Verio will pay to you the remainder of the Employment
             Bonus.

          You acknowledge and agree that any amounts that may become payable to
you (or your successors) pursuant to the grants made as of the Effective Time
(as defined in the Merger Agreement) under the retention and incentive plans
adopted by Verio pursuant to Section 6.14(a) of the Merger Agreement shall be
reduced by the amounts paid to you pursuant to this paragraph 6.

          For purposes of this paragraph 6, the "Employment Bonus" shall mean
(a) two times the sum of:

             (i)  the amount of your annual base salary in effect immediately
             prior to the consummation of the Offer (as defined in the Merger
             Agreement), including all amounts of your annual base salary that
             are then deferred under the qualified and non-qualified employee
             benefit plans of Verio or any other agreement or arrangement; and

             (ii)  the greater of (i) 100% of the last annual incentive payment
             paid or payable to you prior to the consummation of the Offer (as
             defined in the Merger Agreement) under Verio's

                                       4
<PAGE>

             cash bonus incentive plan; and (ii) your incentive target for the
             fiscal year in which such Offer is consummated.

          7.  You acknowledge and agree that your continued employment by Verio
after consummation of the Offer (as defined in the Merger Agreement) and your
participation in Verio's incentive and retention programs thereafter shall be
subject to your execution prior to consummation of the Offer of (i) an agreement
to remain employed by Verio immediately after the consummation of the Offer,
(ii) a written covenant not to compete with or solicit employees of Verio and
its affiliates in the United States for a period ending at the later of two
years following the consummation of the Offer and one year after termination of
employment and (iii) an agreement to maintain the confidentiality of
confidential information and data of Verio and its affiliates, each in a form
reasonably satisfactory to NTT and Verio.

          8.  You acknowledge and agree that prior to consummation of the Offer
you will enter into a Stock Option Deferral Agreement substantially in the form
attached hereto as Exhibit A with respect to each "Company Stock Option" (as
defined in the Merger Agreement) held by  you that waives acceleration and
defers vesting of 20% of the unvested options held by you that would otherwise
automatically become vested immediately prior to consummation of the Offer.

          9.  This letter agreement (and the amendments to the Protection
Agreement contained herein) shall cease to be effective upon the termination of
the Merger Agreement pursuant to its terms.

          10.  Nothing in this letter agreement entitles you to be employed by
Verio for any specific period of time or otherwise interferes with your status
as an employee at will of Verio.

             to which Protected Officer is entitled within five (5) days of the
             date due other than an inadvertent failure, administrative error or
             on account of events beyond the control of the Company;

             (iii)  the Company's requiring Protected Officer to be based at any
             place outside the farther of a 50-mile radius Protected Officer's

             residence prior to the execution of the Merger Agreement, except

             not materially greater than such travel requirements prior to the
             execution of the Merger Agreement, determined without regard to
             travel to meet with representatives of Parent (as defined in the
             Merger Agreement);

               plans listed on Appendix A, in which Protected Officer was
               participating at the execution of the Merger Agreement or which
               are provided to other similarly situated executives of the
               Company, except to the extent such failure is part of a
               comprehensive reduction in compensation or benefits applicable to
               employees of the Company generally so long as the reduction
               applicable to Protected Officer is comparable to the reduction
               applied to other senior executives of the Company;

               (v) the insolvency or the filing (by any party, including the
               Company) of a petition for bankruptcy of the Company, which

               this Agreement, as contemplated by Section 11.1 hereof, provided,
                                                                       --------
               however, that Good Reason shall not include a failure by NTT or
               -------
               any of its affiliates to assume and perform this Agreement; or

             (ix)  For purposes of this Agreement, notwithstanding anything
             contained herein to the contrary, neither (x) any change in the
             Protected Officer's position or responsibilities shall include any
             such change that results primarily from the change in the status of
             the Company from a company the common stock of which is registered
             under the Securities Act of 1934 and traded on a national
             securities exchange to a subsidiary of NTT, nor (y) any change in
             the Protected Officer's amount or level of participation in the
             retention and incentive plan referred to in Section 6.14(a) of the
             Merger Agreement, as compared to the amount or level of
             participation in incentive plans of Verio prior to

                                       10

             consummation of the transactions contemplated by the Merger
             Agreement, shall by itself or in combination with any other event
             or events constitute Good Reason."

          (g)  As used herein, "Cause" means the termination of the Optionee's
                                -----
          Continuous Status as an Employee for "Cause" as such term is defined
          in the Optionee's employment agreement, or in the absence of such
          definition, then as in the determination of the Company, the Optionee:
          (i) acts in bad faith and to the detriment of the Company; (ii)
          refuses or fails to act in substantial accordance with any material
          direction or order of the Company; (iii) exhibits in regard to his
          employment unfitness or unavailability for service, unsatisfactory

by the Company or Related Entity, as the case may be, voluntarily by the
Optionee with Good Reason (as defined above) within twenty-five (25) months of
the Corporate Transaction described in the Merger Agreement, then a pro rata
                                                                    --------

Dear Mr. Fritzinger:

          As you know, Verio Inc. ("Verio") is entering into the Agreement and
Plan of Merger among NTT Communications Corporation, Chaser Acquisition, Inc.
("Acquisition Sub") and Verio Inc. dated as of May 7, 2000 (the "Merger
Agreement") pursuant to which it is anticipated that Acquisition Sub will
acquire all the outstanding capital stock of Verio.  As you also know, Verio has
offered to continue your current employment after the consummation of the Offer
and the Merger (both as defined in the Merger Agreement).  Therefore, in
consideration of such continued employment and the mutual covenants and
agreements contained herein, Verio and you agree as follows:

             part of a comprehensive reduction in compensation or benefits
             applicable to employees of the Company generally so long as the
             reduction applicable to Protected Officer is comparable to the
             reduction applied to other senior executives of the Company."

          3.  Subsection (viii) of Section 2.8(a) of the Protection Agreement is
amended in its entirety to read as follows:

             "(viii)  the failure of the Company to obtain an agreement,

             Agreement, as contemplated by Section 11.1 hereof, provided,

             contained herein to the contrary, neither (i) any change in the
             Protected Officer's position or responsibilities that results
             primarily from the change in the status of the Company from a
             company the common stock of which is registered under the
             Securities Act of 1934 and traded on a national securities exchange
             or the NASDAQ National Market to a subsidiary of NTT, nor (ii) any
             change in the Protected Officer's amount or level of participation
             in the retention and incentive plan referred to in Section 6.14(a)
             of the Merger Agreement, as compared to the amount or level of
             participation in incentive plans of Verio prior to consummation of
             the transactions contemplated by the Merger Agreement, shall by
             itself or in combination with any other event or events constitute
             Good Reason."

          5.  Subsection (iv) of Section 4.1(b) of the Protection Agreement is
amended in its entirety to read as follows:

             "(iv)  the restrictions on any outstanding incentive awards
             (including restricted stock and granted performance shares or

<PAGE>

             units) granted prior to the execution of the Merger Agreement to
             Protected Officer under the Company's stock option and other stock
             incentive plans or under any other incentive plan or arrangement
             shall lapse and such incentive award shall become 100% vested, all
             stock options and stock appreciation rights granted prior to the
             execution of the Merger Agreement to Protected Officer shall become
             immediately exercisable and shall become 100% vested and all
             performance units granted prior to the execution of the Merger
             Agreement shall become 100% vested."

          6.  If you are employed by Verio:

             (i)  thirteen months after the date the Offer (as defined in the
             Merger Agreement) is consummated and have been continuously
             employed by Verio since the date of this letter agreement, Verio
             will pay to you an amount equal to one-half of the Employment Bonus
             (as defined below); and

             (ii)  twenty-five months after the date the Offer (as defined in
             the Merger Agreement) is consummated and have then been
             continuously employed by Verio since the date of this letter
             agreement, Verio will pay to you the remainder of the Employment
             Bonus.

          You acknowledge and agree that any amounts that may become payable to
you (or your successors) pursuant to the grants made as of the Effective Time
(as defined in the Merger Agreement) under the retention and incentive plans
adopted by Verio pursuant to Section 6.14(a) of the Merger Agreement shall be
reduced by the amounts paid to you pursuant to this paragraph 6.

          For purposes of this paragraph 6, the "Employment Bonus" shall mean
(a) two times the sum of:

             (i)  the amount of your annual base salary in effect immediately
             prior to the consummation of the Offer (as defined in the Merger
             Agreement), including all amounts of your annual base salary that
             are then deferred under the qualified and non-qualified employee
             benefit plans of Verio or any other agreement or arrangement; and

             (ii)  the greater of (i) 100% of the last annual incentive payment
             paid or payable to you prior to the consummation of the Offer (as
             defined in the Merger Agreement) under Verio's

                                       4
<PAGE>

             cash bonus incentive plan; and (ii) your incentive target for the
             fiscal year in which such Offer is consummated.

          7.  You acknowledge and agree that your continued employment by Verio
after consummation of the Offer (as defined in the Merger Agreement) and your
participation in Verio's incentive and retention programs thereafter shall be
subject to your execution prior to consummation of the Offer of (i) an agreement
to remain employed by Verio immediately after the consummation of the Offer,
(ii) a written covenant not to compete with or solicit employees of Verio and
its affiliates in the United States for a period ending at the later of two
years following the consummation of the Offer and one year after termination of
employment and (iii) an agreement to maintain the confidentiality of
confidential information and data of Verio and its affiliates, each in a form
reasonably satisfactory to NTT and Verio.

          8.  You acknowledge and agree that prior to consummation of the Offer
you will enter into a Stock Option Deferral Agreement substantially in the form
attached hereto as Exhibit A with respect to each "Company Stock Option" (as
defined in the Merger Agreement) held by  you that waives acceleration and
defers vesting of 20% of the unvested options held by you that would otherwise
automatically become vested immediately prior to consummation of the Offer.

          9.  This letter agreement (and the amendments to the Protection
Agreement contained herein) shall cease to be effective upon the termination of
the Merger Agreement pursuant to its terms.

          10.  Nothing in this letter agreement entitles you to be employed by
Verio for any specific period of time or otherwise interferes with your status
as an employee at will of Verio.

             Protected Officer's position or responsibilities shall include any
             such change that results primarily from the change in the status of

Dear Mr. Kieffer:

          As you know, Verio Inc. ("Verio") is entering into the Agreement and
Plan of Merger among NTT Communications Corporation, Chaser Acquisition, Inc.
("Acquisition Sub") and Verio Inc. dated as of May 7, 2000 (the "Merger
Agreement") pursuant to which it is anticipated that Acquisition Sub will
acquire all the outstanding capital stock of Verio.  As you also know, Verio has
offered to continue your current employment after the consummation of the Offer
and the Merger (both as defined in the Merger Agreement).  Therefore, in
consideration of such continued employment and the mutual covenants and
agreements contained herein, Verio and you agree as follows:

          1.  Effective immediately after consummation of the Offer (as defined
in the Merger Agreement), Section 2.5 of the Compensation Protection Agreement
between Verio and you dated April 1, 1998, (the "Protection Agreement") is
amended by adding the following new subsection (f) immediately following
subsection (e) appearing therein:

             "(f) Notwithstanding anything contained in this Agreement to the
             contrary, no acquisition of the Company's voting securities by, nor
             any merger, consolidation or reorganization of the Company with,
             any entity (or entities) that directly or indirectly is controlled
             by or is under common control with the NTT Communications
             Corporation shall constitute a Change in Control."

          2.  Subsections (i) through (iv) of Section 2.8(a) of the Protection
Agreement are amended in their entirety to read as follows:

             "(i)  (A) a change in Protected Officer's title, position or
             responsibilities (including reporting responsibilities) which
             represent a material adverse change from Protected Officer's title,
             position or responsibilities as in effect at the execution of the
             Agreement and Plan of Merger dated as of May 7, 2000
<PAGE>

             (the "Merger Agreement") among NTT Communications Corporation
             ("NTT"), Chaser Acquisition Inc., and the Company; (B) the
             assignment to Protected Officer of any material duties or
             responsibilities which are significantly inconsistent with
             Protected Officer's title, position or responsibilities as in
             effect at the execution of the Merger Agreement; or (C) any removal
             of Protected Officer from or failure to reappoint or reelect
             Protected Officer to any of such offices or positions, except in
             connection with the termination of Protected Officer's employment
             for Disability, Cause, as a result of Protected Officer's death or
             by Protected Officer other than for Good Reason;

             (ii)  reduction in Protected Officer's base salary to a level below
             that in effect at the execution of the Merger Agreement (except to
             the extent such reduction is part of a comprehensive reduction in
             salary applicable to employees of the Company generally so long as
             the reduction applicable to Protected Officer is comparable to the
             reduction applied to other senior executives of the Company), or
             any failure to pay Protected Officer any compensation or benefits
             to which Protected Officer is entitled within five (5) days of the
             date due other than an inadvertent failure, administrative error or
             on account of events beyond the control of the Company;

             (iii)  the Company's requiring Protected Officer to be based at any
             place outside the farther of a 50-mile radius Protected Officer's
             job location and a 50-mile radius of the Protected Officer's
             residence prior to the execution of the Merger Agreement, except
             for reasonably required travel on the Company's business which is
             not materially greater than such travel requirements prior to the
             execution of the Merger Agreement, determined without regard to
             travel to meet with representatives of Parent (as defined in the
             Merger Agreement); or

             (iv)  the failure by the Company to provide Protected Officer with
             compensation and benefits (other than any compensation or benefits
             under any stock option, stock purchase or other compensation or
             benefit plans, programs or practices payable in or measured by the
             value of the Company's common stock) in the aggregate, not
             significantly less (in terms of benefit levels and/or reward
             opportunities) to those provided under the employee benefit plans,
             programs and practices, including,

                                       2

             but not limited to, the plans listed on Appendix A, in which
             Protected Officer was participating at the execution of the Merger
             Agreement or which are provided to other similarly situated
             executives of the Company, except to the extent such failure is
             part of a comprehensive reduction in compensation or benefits
             applicable to employees of the Company generally so long as the
             reduction applicable to Protected Officer is comparable to the
             reduction applied to other senior executives of the Company."

          3.  Subsection (viii) of Section 2.8(a) of the Protection Agreement is
amended in its entirety to read as follows:

             "(viii)  the failure of the Company to obtain an agreement,
             satisfactory to Protected Officer, from any Successors and Assigns
             (as hereinafter defined) to assume and agree to perform this
             Agreement, as contemplated by Section 11.1 hereof, provided,
                                                                --------
             however, that Good Reason shall not include a failure by NTT or any
             -------
             of its affiliates to assume and perform this Agreement in
             connection with the Merger."

          4.  The following new Section 2.8(d) is added immediately after
Section 2.8(c) of the Protection Agreement:

             "(d)  For purposes of this Agreement, notwithstanding anything
             contained herein to the contrary, neither (i) any change in the
             Protected Officer's position or responsibilities that results
             primarily from the change in the status of the Company from a
             company the common stock of which is registered under the
             Securities Act of 1934 and traded on a national securities exchange
             or the NASDAQ National Market to a subsidiary of NTT, nor (ii) any
             change in the Protected Officer's amount or level of participation
             in the retention and incentive plan referred to in Section 6.14(a)
             of the Merger Agreement, as compared to the amount or level of
             participation in incentive plans of Verio prior to consummation of
             the transactions contemplated by the Merger Agreement, shall by
             itself or in combination with any other event or events constitute
             Good Reason."

          5.  Subsection (iv) of Section 4.1(b) of the Protection Agreement is
amended in its entirety to read as follows:

             "(iv)  the restrictions on any outstanding incentive awards
             (including restricted stock and granted performance shares or

                                       3
<PAGE>

             units) granted prior to the execution of the Merger Agreement to
             Protected Officer under the Company's stock option and other stock
             incentive plans or under any other incentive plan or arrangement
             shall lapse and such incentive award shall become 100% vested, all
             stock options and stock appreciation rights granted prior to the
             execution of the Merger Agreement to Protected Officer shall become
             immediately exercisable and shall become 100% vested and all
             performance units granted prior to the execution of the Merger
             Agreement shall become 100% vested."

          6.  If you are employed by Verio:

             (i)  thirteen months after the date the Offer (as defined in the
             Merger Agreement) is consummated and have been continuously
             employed by Verio since the date of this letter agreement, Verio
             will pay to you an amount equal to one-half of the Employment Bonus
             (as defined below); and

             (ii)  twenty-five months after the date the Offer (as defined in
             the Merger Agreement) is consummated and have then been
             continuously employed by Verio since the date of this letter
             agreement, Verio will pay to you the remainder of the Employment
             Bonus.

          You acknowledge and agree that any amounts that may become payable to
you (or your successors) pursuant to the grants made as of the Effective Time
(as defined in the Merger Agreement) under the retention and incentive plans
adopted by Verio pursuant to Section 6.14(a) of the Merger Agreement shall be
reduced by the amounts paid to you pursuant to this paragraph 6.

          For purposes of this paragraph 6, the "Employment Bonus" shall mean
(a) two times the sum of:

             (i)  the amount of your annual base salary in effect immediately
             prior to the consummation of the Offer (as defined in the Merger
             Agreement), including all amounts of your annual base salary that
             are then deferred under the qualified and non-qualified employee
             benefit plans of Verio or any other agreement or arrangement; and

             (ii)  the greater of (i) 100% of the last annual incentive payment
             paid or payable to you prior to the consummation of the Offer (as
             defined in the Merger Agreement) under Verio's

                                       4

             cash bonus incentive plan; and (ii) your incentive target for the
             fiscal year in which such Offer is consummated.

          7.  You acknowledge and agree that your continued employment by Verio
after consummation of the Offer (as defined in the Merger Agreement) and your
participation in Verio's incentive and retention programs thereafter shall be
subject to your execution prior to consummation of the Offer of (i) an agreement
to remain employed by Verio immediately after the consummation of the Offer,
(ii) a written covenant not to compete with or solicit employees of Verio and
its affiliates in the United States for a period ending at the later of two
years following the consummation of the Offer and one year after termination of
employment and (iii) an agreement to maintain the confidentiality of
confidential information and data of Verio and its affiliates, each in a form
reasonably satisfactory to NTT and Verio.

          8.  You acknowledge and agree that prior to consummation of the Offer
you will enter into a Stock Option Deferral Agreement substantially in the form
attached hereto as Exhibit A with respect to each "Company Stock Option" (as
defined in the Merger Agreement) held by  you that waives acceleration and
defers vesting of 20% of the unvested options held by you that would otherwise
automatically become vested immediately prior to consummation of the Offer.

          9.  This letter agreement (and the amendments to the Protection
Agreement contained herein) shall cease to be effective upon the termination of
the Merger Agreement pursuant to its terms.

Verio for any specific period of time or otherwise interferes with your status
as an employee at will of Verio.

               -------
               any of its affiliates to assume and perform this Agreement; or

             (ix)  For purposes of this Agreement, notwithstanding anything
             contained herein to the contrary, neither (x) any change in the
             Protected Officer's position or responsibilities shall include any
             such change that results primarily from the change in the status of
             the Company from a company the common stock of which is registered
             under the Securities Act of 1934 and traded on a national
             securities exchange to a subsidiary of NTT, nor (y) any change in

          Continuous Status as an Employee for "Cause" as such term is defined
          in the Optionee's employment agreement, or in the absence of such
          definition, then as in the determination of the Company, the Optionee:
          (i) acts in bad faith and to the detriment of the Company; (ii)
          refuses or fails to act in substantial accordance with any material
          direction or order of the Company; (iii) exhibits in regard to his

Dear Mr. Orland:

          As you know, Verio Inc. ("Verio") is entering into the Agreement and
Plan of Merger among NTT Communications Corporation, Chaser Acquisition, Inc.
("Acquisition Sub") and Verio Inc. dated as of May 7, 2000 (the "Merger
Agreement") pursuant to which it is anticipated that Acquisition Sub will
acquire all the outstanding capital stock of Verio.  As you also know, Verio has
offered to continue your current employment after the consummation of the Offer
and the Merger (both as defined in the Merger Agreement).  Therefore, in
consideration of such continued employment and the mutual covenants and
agreements contained herein, Verio and you agree as follows:

          1. Effective immediately after consummation of the Offer (as defined
in the Merger Agreement), Section 2.5 of the Compensation Protection Agreement
between Verio and you dated August 19, 1999, (the "Protection Agreement") is
amended by adding the following new subsection (f) immediately following
subsection (e) appearing therein:

             "(f) Notwithstanding anything contained in this Agreement to the
             contrary, no acquisition of the Company's voting securities by, nor
             any merger, consolidation or reorganization of the Company with,
             any entity (or entities) that directly or indirectly is controlled
             by or is under common control with the NTT Communications
             Corporation shall constitute a Change in Control."

          2.  Subsections (i) through (iv) of Section 2.8(a) of the Protection
Agreement are amended in their entirety to read as follows:

             "(i)  (A) a change in Protected Officer's title, position or
             responsibilities (including reporting responsibilities) which
             represent a material adverse change from Protected Officer's title,
             position or responsibilities as in effect at the execution of the
             Agreement and Plan of Merger dated as of May 7, 2000

             effect at the execution of the Merger Agreement; or (C) any removal
             of Protected Officer from or failure to reappoint or reelect

             for Disability, Cause, as a result of Protected Officer's death or
             by Protected Officer other than for Good Reason;

             (ii)  reduction in Protected Officer's base salary to a level below
             that in effect at the execution of the Merger Agreement (except to

             salary applicable to employees of the Company generally so long as
             the reduction applicable to Protected Officer is comparable to the
             reduction applied to other senior executives of the Company), or
             any failure to pay Protected Officer any compensation or benefits
             to which Protected Officer is entitled within five (5) days of the
             date due other than an inadvertent failure, administrative error or
             on account of events beyond the control of the Company;

             (iii)  the Company's requiring Protected Officer to be based at any

             compensation and benefits (other than any compensation or benefits
             under any stock option, stock purchase or other compensation or

             reduction applicable to Protected Officer is comparable to the
             reduction applied to other senior executives of the Company."

          3.  Subsection (viii) of Section 2.8(a) of the Protection Agreement is
amended in its entirety to read as follows:

             "(viii)  the failure of the Company to obtain an agreement,

             Agreement, as contemplated by Section 11.1 hereof, provided,

             however, that Good Reason shall not include a failure by NTT or any
             -------
             of its affiliates to assume and perform this Agreement in
             connection with the Merger."

          4.  The following new Section 2.8(d) is added immediately after
Section 2.8(c) of the Protection Agreement:

             "(d)  For purposes of this Agreement, notwithstanding anything
             contained herein to the contrary, neither (i) any change in the
             Protected Officer's position or responsibilities that results
             primarily from the change in the status of the Company from a
             company the common stock of which is registered under the
             Securities Act of 1934 and traded on a national securities exchange
             or the NASDAQ National Market to a subsidiary of NTT, nor (ii) any
             change in the Protected Officer's amount or level of participation
             in the retention and incentive plan referred to in Section 6.14(a)
             of the Merger Agreement, as compared to the amount or level of
             participation in incentive plans of Verio prior to consummation of
             the transactions contemplated by the Merger Agreement, shall by
             itself or in combination with any other event or events constitute
             Good Reason."

          5.  Subsection (iv) of Section 4.1(b) of the Protection Agreement is
amended in its entirety to read as follows:

             "(iv)  the restrictions on any outstanding incentive awards
             (including restricted stock and granted performance shares or

<PAGE>

             units) granted prior to the execution of the Merger Agreement to
             Protected Officer under the Company's stock option and other stock
             incentive plans or under any other incentive plan or arrangement
             shall lapse and such incentive award shall become 100% vested, all
             stock options and stock appreciation rights granted prior to the
             execution of the Merger Agreement to Protected Officer shall become
             immediately exercisable and shall become 100% vested and all
             performance units granted prior to the execution of the Merger
             Agreement shall become 100% vested."

          6.  If you are employed by Verio:

             (i)  thirteen months after the date the Offer (as defined in the
             Merger Agreement) is consummated and have been continuously
             employed by Verio since the date of this letter agreement, Verio
             will pay to you an amount equal to one-half of the Employment Bonus
             (as defined below); and

             (ii)  twenty-five months after the date the Offer (as defined in

             agreement, Verio will pay to you the remainder of the Employment
             Bonus.

          You acknowledge and agree that any amounts that may become payable to
you (or your successors) pursuant to the grants made as of the Effective Time
(as defined in the Merger Agreement) under the retention and incentive plans

             Agreement), including all amounts of your annual base salary that
             are then deferred under the qualified and non-qualified employee
             benefit plans of Verio or any other agreement or arrangement; and

             (ii)  the greater of (i) 100% of the last annual incentive payment
             paid or payable to you prior to the consummation of the Offer (as
             defined in the Merger Agreement) under Verio's

Dear Ms. Goworowski:

          As you know, Verio Inc. ("Verio") is entering into the Agreement and
Plan of Merger among NTT Communications Corporation, Chaser Acquisition, Inc.
("Acquisition Sub") and Verio Inc. dated as of May 7, 2000 (the "Merger
Agreement") pursuant to which it is anticipated that Acquisition Sub will
acquire all the outstanding capital stock of Verio.  As you also know, Verio has
offered to continue your current employment after the consummation of the Offer
and the Merger (both as defined in the Merger Agreement).  Therefore, in
consideration of such continued employment and the mutual covenants and
agreements contained herein, Verio and you agree as follows:

          1. Effective immediately after consummation of the Offer (as defined
in the Merger Agreement), Section 2.5 of the Compensation Protection Agreement
between Verio and you dated October 18, 1999, (the "Protection Agreement") is
amended by adding the following new subsection (f) immediately following
subsection (e) appearing therein:

             "(f) Notwithstanding anything contained in this Agreement to the
             contrary, no acquisition of the Company's voting securities by, nor
             any merger, consolidation or reorganization of the Company with,
             any entity (or entities) that directly or indirectly is controlled
             by or is under common control with the NTT Communications
             Corporation shall constitute a Change in Control."

          2.  Subsections (i) through (iv) of Section 2.8(a) of the Protection
Agreement are amended in their entirety to read as follows:

             "(i)  (A) a change in Protected Officer's title, position or
             responsibilities (including reporting responsibilities) which
             represent a material adverse change from Protected Officer's title,
             position or responsibilities as in effect at the execution of the
             Agreement and Plan of Merger dated as of May 7, 2000
<PAGE>

             (the "Merger Agreement") among NTT Communications Corporation
             ("NTT"), Chaser Acquisition Inc., and the Company; (B) the
             assignment to Protected Officer of any material duties or
             responsibilities which are significantly inconsistent with
             Protected Officer's title, position or responsibilities as in
             effect at the execution of the Merger Agreement; or (C) any removal
             of Protected Officer from or failure to reappoint or reelect
             Protected Officer to any of such offices or positions, except in
             connection with the termination of Protected Officer's employment
             for Disability, Cause, as a result of Protected Officer's death or
             by Protected Officer other than for Good Reason;

             (ii)  reduction in Protected Officer's base salary to a level below
             that in effect at the execution of the Merger Agreement (except to
             the extent such reduction is part of a comprehensive reduction in
             salary applicable to employees of the Company generally so long as
             the reduction applicable to Protected Officer is comparable to the
             reduction applied to other senior executives of the Company), or
             any failure to pay Protected Officer any compensation or benefits
             to which Protected Officer is entitled within five (5) days of the
             date due other than an inadvertent failure, administrative error or
             on account of events beyond the control of the Company;

             (iii)  the Company's requiring Protected Officer to be based at any
             place outside the farther of a 50-mile radius Protected Officer's
             job location and a 50-mile radius of the Protected Officer's
             residence prior to the execution of the Merger Agreement, except
             for reasonably required travel on the Company's business which is
             not materially greater than such travel requirements prior to the
             execution of the Merger Agreement, determined without regard to
             travel to meet with representatives of Parent (as defined in the
             Merger Agreement); or

             (iv)  the failure by the Company to provide Protected Officer with
             compensation and benefits (other than any compensation or benefits
             under any stock option, stock purchase or other compensation or
             benefit plans, programs or practices payable in or measured by the
             value of the Company's common stock) in the aggregate, not
             significantly less (in terms of benefit levels and/or reward
             opportunities) to those provided under the employee benefit plans,

             Agreement or which are provided to other similarly situated

             part of a comprehensive reduction in compensation or benefits
             applicable to employees of the Company generally so long as the
             reduction applicable to Protected Officer is comparable to the
             reduction applied to other senior executives of the Company."

          3.  Subsection (viii) of Section 2.8(a) of the Protection Agreement is
amended in its entirety to read as follows:

             "(viii)  the failure of the Company to obtain an agreement,
             satisfactory to Protected Officer, from any Successors and Assigns
             (as hereinafter defined) to assume and agree to perform this
             Agreement, as contemplated by Section 11.1 hereof, provided,

             however, that Good Reason shall not include a failure by NTT or any
             -------
             of its affiliates to assume and perform this Agreement in
             connection with the Merger."

          4.  The following new Section 2.8(d) is added immediately after
Section 2.8(c) of the Protection Agreement:

             "(d)  For purposes of this Agreement, notwithstanding anything
             contained herein to the contrary, neither (i) any change in the
             Protected Officer's position or responsibilities that results
             primarily from the change in the status of the Company from a
             company the common stock of which is registered under the
             Securities Act of 1934 and traded on a national securities exchange
             or the NASDAQ National Market to a subsidiary of NTT, nor (ii) any
             change in the Protected Officer's amount or level of participation
             in the retention and incentive plan referred to in Section 6.14(a)
             of the Merger Agreement, as compared to the amount or level of
             participation in incentive plans of Verio prior to consummation of
             the transactions contemplated by the Merger Agreement, shall by
             itself or in combination with any other event or events constitute
             Good Reason."

          5.  Subsection (iv) of Section 4.1(b) of the Protection Agreement is
amended in its entirety to read as follows:

             "(iv)  the restrictions on any outstanding incentive awards
             (including restricted stock and granted performance shares or

             Protected Officer under the Company's stock option and other stock
             incentive plans or under any other incentive plan or arrangement
             shall lapse and such incentive award shall become 100% vested, all
             stock options and stock appreciation rights granted prior to the
             execution of the Merger Agreement to Protected Officer shall become
             immediately exercisable and shall become 100% vested and all
             performance units granted prior to the execution of the Merger
             Agreement shall become 100% vested."

          6.  If you are employed by Verio:

             (i)  thirteen months after the date the Offer (as defined in the
             Merger Agreement) is consummated and have been continuously
             employed by Verio since the date of this letter agreement, Verio
             will pay to you an amount equal to one-half of the Employment Bonus
             (as defined below); and

             (ii)  twenty-five months after the date the Offer (as defined in
             the Merger Agreement) is consummated and have then been

             agreement, Verio will pay to you the remainder of the Employment
             Bonus.

          You acknowledge and agree that any amounts that may become payable to
you (or your successors) pursuant to the grants made as of the Effective Time
(as defined in the Merger Agreement) under the retention and incentive plans
adopted by Verio pursuant to Section 6.14(a) of the Merger Agreement shall be
reduced by the amounts paid to you pursuant to this paragraph 6.

          For purposes of this paragraph 6, the "Employment Bonus" shall mean

             (i)  the amount of your annual base salary in effect immediately
             prior to the consummation of the Offer (as defined in the Merger
             Agreement), including all amounts of your annual base salary that
             are then deferred under the qualified and non-qualified employee
             benefit plans of Verio or any other agreement or arrangement; and

             (ii)  the greater of (i) 100% of the last annual incentive payment
             paid or payable to you prior to the consummation of the Offer (as
             defined in the Merger Agreement) under Verio's

             fiscal year in which such Offer is consummated.

          7.  You acknowledge and agree that your continued employment by Verio

participation in Verio's incentive and retention programs thereafter shall be
subject to your execution prior to consummation of the Offer of (i) an agreement
to remain employed by Verio immediately after the consummation of the Offer,
(ii) a written covenant not to compete with or solicit employees of Verio and
its affiliates in the United States for a period ending at the later of two
years following the consummation of the Offer and one year after termination of
employment and (iii) an agreement to maintain the confidentiality of
confidential information and data of Verio and its affiliates, each in a form
reasonably satisfactory to NTT and Verio.

          8.  This letter agreement (and the amendments to the Protection
Agreement contained herein) shall cease to be effective upon the termination of
the Merger Agreement pursuant to its terms.

          9.  Nothing in this letter agreement entitles you to be employed by
Verio for any specific period of time or otherwise interferes with your status
as an employee at will of Verio.

Dear Mr. Schneider:

          As you know, Verio Inc. ("Verio") is entering into the Agreement and
Plan of Merger among NTT Communications Corporation, Chaser Acquisition, Inc.
("Acquisition Sub") and Verio Inc. dated as of May 7, 2000 (the "Merger
Agreement") pursuant to which it is anticipated that Acquisition Sub will
acquire all the outstanding capital stock of Verio.  As you also know, Verio has
offered to continue your current employment after the consummation of the Offer
and the Merger (both as defined in the Merger Agreement).  Therefore, in
consideration of such continued employment and the mutual covenants and
agreements contained herein, Verio and you agree as follows:

          1.  Effective immediately after consummation of the Offer (as defined
in the Merger Agreement), Section 2.5 of the Compensation Protection Agreement
between Verio and you dated September 3, 1998, (the "Protection Agreement") is
amended by adding the following new subsection (f) immediately following
subsection (e) appearing therein:

             "(f) Notwithstanding anything contained in this Agreement to the
             contrary, no acquisition of the Company's voting securities by, nor
             any merger, consolidation or reorganization of the Company with,
             any entity (or entities) that directly or indirectly is controlled
             by or is under common control with the NTT Communications
             Corporation shall constitute a Change in Control."

          2.  Subsections (i) through (iv) of Section 2.8(a) of the Protection
Agreement are amended in their entirety to read as follows:

             "(i)  (A) a change in Protected Officer's title, position or
             responsibilities (including reporting responsibilities) which
             represent a material adverse change from Protected Officer's title,
             position or responsibilities as in effect at the execution of the
             Agreement and Plan of Merger dated as of May 7, 2000
<PAGE>

             (the "Merger Agreement") among NTT Communications Corporation
             ("NTT"), Chaser Acquisition Inc., and the Company; (B) the
             assignment to Protected Officer of any material duties or
             responsibilities which are significantly inconsistent with
             Protected Officer's title, position or responsibilities as in
             effect at the execution of the Merger Agreement; or (C) any removal
             of Protected Officer from or failure to reappoint or reelect
             Protected Officer to any of such offices or positions, except in
             connection with the termination of Protected Officer's employment
             for Disability, Cause, as a result of Protected Officer's death or
             by Protected Officer other than for Good Reason;

             (ii)  reduction in Protected Officer's base salary to a level below
             that in effect at the execution of the Merger Agreement (except to
             the extent such reduction is part of a comprehensive reduction in
             salary applicable to employees of the Company generally so long as
             the reduction applicable to Protected Officer is comparable to the
             reduction applied to other senior executives of the Company), or
             any failure to pay Protected Officer any compensation or benefits
             to which Protected Officer is entitled within five (5) days of the
             date due other than an inadvertent failure, administrative error or
             on account of events beyond the control of the Company;

             (iii)  the Company's requiring Protected Officer to be based at any
             place outside the farther of a 50-mile radius Protected Officer's
             job location and a 50-mile radius of the Protected Officer's
             residence prior to the execution of the Merger Agreement, except
             for reasonably required travel on the Company's business which is
             not materially greater than such travel requirements prior to the
             execution of the Merger Agreement, determined without regard to
             travel to meet with representatives of Parent (as defined in the
             Merger Agreement); or

             (iv)  the failure by the Company to provide Protected Officer with
             compensation and benefits (other than any compensation or benefits
             under any stock option, stock purchase or other compensation or
             benefit plans, programs or practices payable in or measured by the
             value of the Company's common stock) in the aggregate, not
             significantly less (in terms of benefit levels and/or reward
             opportunities) to those provided under the employee benefit plans,
             programs and practices, including,

             but not limited to, the plans listed on Appendix A, in which
             Protected Officer was participating at the execution of the Merger
             Agreement or which are provided to other similarly situated
             executives of the Company, except to the extent such failure is
             part of a comprehensive reduction in compensation or benefits
             applicable to employees of the Company generally so long as the
             reduction applicable to Protected Officer is comparable to the
             reduction applied to other senior executives of the Company."

          3.  Subsection (viii) of Section 2.8(a) of the Protection Agreement is
amended in its entirety to read as follows:

             "(viii)  the failure of the Company to obtain an agreement,
             satisfactory to Protected Officer, from any Successors and Assigns
             (as hereinafter defined) to assume and agree to perform this
             Agreement, as contemplated by Section 11.1 hereof, provided,
                                                                --------
             however, that Good Reason shall not include a failure by NTT or any
             -------
             of its affiliates to assume and perform this Agreement in
             connection with the Merger."

          4.  The following new Section 2.8(d) is added immediately after
Section 2.8(c) of the Protection Agreement:

             "(d)  For purposes of this Agreement, notwithstanding anything
             contained herein to the contrary, neither (i) any change in the
             Protected Officer's position or responsibilities that results
             primarily from the change in the status of the Company from a
             company the common stock of which is registered under the
             Securities Act of 1934 and traded on a national securities exchange
             or the NASDAQ National Market to a subsidiary of NTT, nor (ii) any
             change in the Protected Officer's amount or level of participation
             in the retention and incentive plan referred to in Section 6.14(a)
             of the Merger Agreement, as compared to the amount or level of
             participation in incentive plans of Verio prior to consummation of
             the transactions contemplated by the Merger Agreement, shall by
             itself or in combination with any other event or events constitute
             Good Reason."

          5.  Subsection (iv) of Section 4.1(b) of the Protection Agreement is
amended in its entirety to read as follows:

             "(iv)  the restrictions on any outstanding incentive awards
             (including restricted stock and granted performance shares or

                                       3
<PAGE>

             units) granted prior to the execution of the Merger Agreement to
             Protected Officer under the Company's stock option and other stock
             incentive plans or under any other incentive plan or arrangement
             shall lapse and such incentive award shall become 100% vested, all
             stock options and stock appreciation rights granted prior to the
             execution of the Merger Agreement to Protected Officer shall become
             immediately exercisable and shall become 100% vested and all
             performance units granted prior to the execution of the Merger
             Agreement shall become 100% vested."

         6.  If you are employed by Verio:

             (i)  thirteen months after the date the Offer (as defined in the
             Merger Agreement) is consummated and have been continuously
             employed by Verio since the date of this letter agreement, Verio
             will pay to you an amount equal to one-half of the Employment Bonus
             (as defined below); and

             (ii)  twenty-five months after the date the Offer (as defined in
             the Merger Agreement) is consummated and have then been
             continuously employed by Verio since the date of this letter
             agreement, Verio will pay to you the remainder of the Employment
             Bonus.

          You acknowledge and agree that any amounts that may become payable to
you (or your successors) pursuant to the grants made as of the Effective Time
(as defined in the Merger Agreement) under the retention and incentive plans
adopted by Verio pursuant to Section 6.14(a) of the Merger Agreement shall be
reduced by the amounts paid to you pursuant to this paragraph 6.

          For purposes of this paragraph 6, the "Employment Bonus" shall mean
(a) two times the sum of:

             (i)  the amount of your annual base salary in effect immediately
             prior to the consummation of the Offer (as defined in the Merger
             Agreement), including all amounts of your annual base salary that
             are then deferred under the qualified and non-qualified employee
             benefit plans of Verio or any other agreement or arrangement; and

             (ii)  the greater of (i) 100% of the last annual incentive payment
             paid or payable to you prior to the consummation of the Offer (as
             defined in the Merger Agreement) under Verio's

                                       4

             cash bonus incentive plan; and (ii) your incentive target for the
             fiscal year in which such Offer is consummated.

          7.  You acknowledge and agree that your continued employment by Verio
after consummation of the Offer (as defined in the Merger Agreement) and your
participation in Verio's incentive and retention programs thereafter shall be
subject to your execution prior to consummation of the Offer of (i) an agreement
to remain employed by Verio immediately after the consummation of the Offer,
(ii) a written covenant not to compete with or solicit employees of Verio and
its affiliates in the United States for a period ending at the later of two
years following the consummation of the Offer and one year after termination of
employment and (iii) an agreement to maintain the confidentiality of
confidential information and data of Verio and its affiliates, each in a form
reasonably satisfactory to NTT and Verio.

          8.  This letter agreement (and the amendments to the Protection
Agreement contained herein) shall cease to be effective upon the termination of
the Merger Agreement pursuant to its terms.

          9.  Nothing in this letter agreement entitles you to be employed by

             units) granted prior to the execution of the Merger Agreement to
             Protected Officer under the Company's stock option and other stock
             incentive plans or under any other incentive plan or arrangement
             shall lapse and such incentive award shall become 100% vested, all

             Agreement shall become 100% vested."

         6.  If you are employed by Verio:

             (i)  thirteen months after the date the Offer (as defined in the
             Merger Agreement) is consummated and have been continuously
             employed by Verio since the date of this letter agreement, Verio
             will pay to you an amount equal to one-half of the Employment Bonus
             (as defined below); and

             (ii)  twenty-five months after the date the Offer (as defined in
             the Merger Agreement) is consummated and have then been
             continuously employed by Verio since the date of this letter
             agreement, Verio will pay to you the remainder of the Employment
             Bonus.

          You acknowledge and agree that any amounts that may become payable to
you (or your successors) pursuant to the grants made as of the Effective Time
(as defined in the Merger Agreement) under the retention and incentive plans
adopted by Verio pursuant to Section 6.14(a) of the Merger Agreement shall be
reduced by the amounts paid to you pursuant to this paragraph 6.

          For purposes of this paragraph 6, the "Employment Bonus" shall mean
(a) two times the sum of:

             (i)  the amount of your annual base salary in effect immediately
             prior to the consummation of the Offer (as defined in the Merger
             Agreement), including all amounts of your annual base salary that
             are then deferred under the qualified and non-qualified employee
             benefit plans of Verio or any other agreement or arrangement; and

             (ii)  the greater of (i) 100% of the last annual incentive payment
             paid or payable to you prior to the consummation of the Offer (as
             defined in the Merger Agreement) under Verio's

                                       4

             cash bonus incentive plan; and (ii) your incentive target for the
             fiscal year in which such Offer is consummated.

          7.  You acknowledge and agree that your continued employment by Verio
after consummation of the Offer (as defined in the Merger Agreement) and your
participation in Verio's incentive and retention programs thereafter shall be
subject to your execution prior to consummation of the Offer of (i) an agreement
to remain employed by Verio immediately after the consummation of the Offer,
(ii) a written covenant not to compete with or solicit employees of Verio and
its affiliates in the United States for a period ending at the later of two
years following the consummation of the Offer and one year after termination of
employment and (iii) an agreement to maintain the confidentiality of
confidential information and data of Verio and its affiliates, each in a form
reasonably satisfactory to NTT and Verio.

          8.  This letter agreement (and the amendments to the Protection
Agreement contained herein) shall cease to be effective upon the termination of
the Merger Agreement pursuant to its terms.

          9.  Nothing in this letter agreement entitles you to be employed by
Verio for any specific period of time or otherwise interferes with your status
as an employee at will of Verio.
