         Item 6. Indemnification of Directors and Officers

         Section 145(a) of the General Corporation Law of the State of Delaware
provides that a Delaware corporation may indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation or enterprise,
against expenses, judgments, fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had no cause to believe his conduct was unlawful.

         Section 145(b) provides that a Delaware corporation may indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that such
person acted in any of the capacities set forth above, against expenses actually
and reasonably incurred by him in connection with the defense or settlement of
such action or suit if he acted under similar standards, except that no
indemnification may be made in respect of any claim, issue or matter as to which
such person shall have been adjudged to be liable to the corporation unless and
only to the extent that the court in which such action or suit was brought shall
determine that despite the adjudication of liability, such person is fairly and
reasonably entitled to be indemnified for such expenses which the court shall
deem proper.

         Section 145 further provides that (i) to the extent a director or
officer of a corporation has been successful in the defense of any action, suit
or proceeding referred to in subsections (a) and (b) or in the defense of any
claim, issue, or matter therein, he shall be indemnified against expenses
actually and reasonably incurred by him in connection therewith, (ii)
indemnification provided for by Section 145 shall not be deemed exclusive of any
other rights to which the indemnified party may be entitled, and (iii) the
corporation may purchase and maintain insurance on behalf of a director or
officer of the corporation against any liability asserted against him or
incurred by him in any such capacity or arising out of his status as such
whether or not the corporation would have the power to indemnify him against
such liabilities under Section 145.

         Section 102(b)(7) of the General Corporation Law provides that a
corporation in its original certificate of incorporation or an amendment thereto
validly approved by stockholders may eliminate or limit personal liability of
the members of its board of directors or governing body for breach of a
director's fiduciary duty. However, no such provision may eliminate or limit the
liability of a director for breaching his duty of loyalty, failing to act in
good faith, engaging in intentional misconduct or knowingly violating a law,
paying a dividend or approving a stock repurchase which was illegal, or
obtaining an improper personal benefit. A provision of this type has no effect
on the availability of equitable remedies, such as an injunction or rescission,
for breach of fiduciary duty. The Company's Charter contains such a provision.

         The Company's Charter further provides that the Company shall indemnify
its officers and directors and, to the extent authorized by the Board of
Directors, employees and agents of the Company, to the fullest extent permitted
by and in the manner permissible under the laws of the State of Delaware.

         The Company's Directors' and Officers' liability insurance policy is
designed to reimburse the Company for payments made by it pursuant to the
foregoing indemnification. This policy has aggregate coverage of $25 million.

         Pursuant to the Merger Agreement with AboveNet and Merger Sub,
following its acquisition of AboveNet, the Company is required to maintain for
not less than six years all rights to indemnification existing in favor of any
current of former employee, agent, director or officer of AboveNet or any of its
subsidiaries (the


                                       5
<PAGE>

"Indemnified Parties") as provided in their respective charter or by-laws, or an
agreement between an Indemnified Party and AboveNet or any of its subsidiaries,
or otherwise in effect on June 22, 1999, subject to certain limitations.
Additionally, pursuant to the Merger Agreement, following its acquisition of
AboveNet, the Company will indemnify and hold harmless all Indemnified Parties
to the fullest extent permitted by law with respect to all acts and omissions
(occurring prior to the acquisition of AboveNet, but including the transactions
contemplated by the Merger Agreement) arising out of such persons' services as
employees, agents, directors or officers of AboveNet or any of its subsidiaries,
or as trustees or fiduciaries of any plan for the benefit of employees of, or
otherwise on behalf of, AboveNet or any of its subsidiaries, subject to certain
limitations. In the event that any Indemnified Party is or becomes involved in
any capacity in any action, proceeding or investigation in connection with any
matter occurring at the time of or prior to its acquisition of AboveNet, the
Company will pay as incurred such Indemnified Party's legal and other expenses
(including the cost of any investigation and preparation) incurred in connection
with such action, proceeding or investigation.

         This summary is subject to the General Corporation Law of the State of
Delaware, the Charter and the By-laws of the Company and the agreements referred
to above.

         Item 9. Undertakings

         (a) The undersigned registrant hereby undertakes the following: (i) to
file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement to include any material
information with respect to the plan of distribution not previously disclosed in
this Registration Statement or any material change to such information in this
Registration Statement; (ii) that, for the purpose of determining any liability
under the Securities Act, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof; and (iii) to remove from registration by means of a
post-effective amendment any of the securities being registered which remain
unsold at the termination of the offering.

         (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934, as amended, that is incorporated by reference
in this Registration Statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

         (c) Insofar as indemnification for liabilities arising under the
Securities Act, may be permitted to directors, officers and controlling persons
of the registrant pursuant to the registrant's charter or by-laws, by contract,
or otherwise, the registrant has been advised that, in the opinion of the SEC,
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will,


                                       7
<PAGE>

unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

                            1998 STOCK INCENTIVE PLAN

ARTICLE 1.   INTRODUCTION.

     The Plan was adopted by the Board effective December 9, 1998. The
purpose of the Plan is to promote the long-term success of the Company and
the creation of stockholder value by (a) encouraging Employees, Outside
Directors and Consultants to focus on critical long-range objectives, (b)
encouraging the attraction and retention of Employees, Outside Directors and
Consultants with exceptional qualifications and (c) linking Employees,
Outside Directors and Consultants directly to stockholder interests through
increased stock ownership. The Plan seeks to achieve this purpose by
providing for Awards in the form of Restricted Shares or Options (which may
constitute incentive stock options or nonstatutory stock options).

     The Plan shall be governed by, and construed in accordance with, the laws
of the State of Delaware (except their choice-of-law provisions).

ARTICLE 2.   ADMINISTRATION.

     2.1  COMMITTEE COMPOSITION. The Plan shall be administered by the
Committee. The Committee shall consist exclusively of two or more directors of
the Company, who shall be appointed by the Board. In addition, the composition
of the Committee shall satisfy:

          (a)  Such requirements as the Securities and Exchange Commission may
     establish for administrators acting under plans intended to qualify for
     exemption under Rule 16b-3 (or its successor) under the Exchange Act; and

          (b)  Such requirements as the Internal Revenue Service may establish
     for outside directors acting under plans intended to qualify for exemption
     under section 162(m)(4)(C) of the Code.

     2.2  COMMITTEE RESPONSIBILITIES. The Committee shall (a) select the
Employees, Outside Directors and Consultants who are to receive Awards under the
Plan, (b) determine the type, number, vesting requirements and other features
and conditions of such Awards, (c) interpret the Plan and (d) make all other
decisions relating to the operation of the Plan. The Committee may adopt such
rules or guidelines as it deems appropriate to implement the Plan. The
Committee's determinations under the Plan shall be final and binding on all
persons.

     2.3  COMMITTEE FOR NON-OFFICER GRANTS. The Board may also appoint a
secondary committee of the Board, which shall be composed of one or more
directors of the Company who need not satisfy the requirements of Section 2.1.
Such secondary committee may administer the Plan with respect to Employees and
Consultants who are not considered officers or directors of the Company under
section 16 of the Exchange Act, may grant Awards under the Plan to such
Employees and Consultants and may determine all features and conditions of such
Awards.

<PAGE>

Within the limitations of this Section 2.3, any reference in the Plan to the
Committee shall include such secondary committee.

ARTICLE 3.   SHARES AVAILABLE FOR GRANTS.

     3.1  BASIC LIMITATION. Common Shares issued pursuant to the Plan may be
authorized but unissued shares or treasury shares. The aggregate number of
Options and Restricted Shares awarded under the Plan shall not exceed (a)
2,500,000 plus (b) the additional Common Shares described in Sections 3.2 and
3.3. The limitations of this Section 3.1 and Section 3.2 shall be subject to
adjustment pursuant to Article 9.

     3.2  ANNUAL INCREASE IN SHARES. As of the first day of each fiscal year,
commencing with July 1, 1999, the aggregate number of Options and Restricted
Shares that may be awarded under the Plan shall automatically increase by a
number equal to the lesser of (a) 4% of the total number of Common Shares then
outstanding or (b) 500,000.

     3.3  ADDITIONAL SHARES. If Options are forfeited or terminate for any other
reason before being exercised, then the corresponding Common Shares shall again
become available for the grant of Options or Restricted Shares under the Plan.
If Restricted Shares or Common Shares issued upon the exercise of Options are
forfeited, then such Common Shares shall again become available for the grant of
NSOs and Restricted Shares under the Plan. The aggregate number of Common Shares
that may be issued under the Plan upon the exercise of ISOs shall not be
increased when Restricted Shares or other Common Shares are forfeited.

ARTICLE 4.   ELIGIBILITY.

     4.1  NONSTATUTORY STOCK OPTIONS AND RESTRICTED SHARES. Only Employees,
Outside Directors and Consultants shall be eligible for the grant of NSOs and
Restricted Shares.

     4.2  INCENTIVE STOCK OPTIONS. Only Employees who are common-law employees
of the Company, a Parent or a Subsidiary shall be eligible for the grant of
ISOs. In addition, an Employee who owns more than 10% of the total combined
voting power of all classes of outstanding stock of the Company or any of its
Parents or Subsidiaries shall not be eligible for the grant of an ISO unless the
requirements set forth in section 422(c)(6) of the Code are satisfied.

ARTICLE 5.   OPTIONS.

     5.1  STOCK OPTION AGREEMENT. Each grant of an Option under the Plan shall
be evidenced by a Stock Option Agreement between the Optionee and the Company.
Such Option shall be subject to all applicable terms of the Plan and may be
subject to any other terms that are not inconsistent with the Plan. The
provisions of the various Stock Option Agreements entered into under the Plan
need not be identical. Options may be granted in consideration of a reduction in
the Optionee's other compensation. A Stock Option Agreement may provide that a
new Option will be granted automatically to the Optionee when he or she
exercises a prior Option and pays the Exercise Price in the form described in
Section 6.2.

                                       2
<PAGE>

     5.2  NUMBER OF SHARES. Each Stock Option Agreement shall specify the number
of Common Shares subject to the Option and shall provide for the adjustment of
such number in accordance with Article 9. Options granted to any Optionee in a
single fiscal year of the Company shall not cover more than 500,000 Common
Shares, except that Options granted to a new Employee in the fiscal year of the
Company in which his or her service as an Employee first commences shall not
cover more than 1,000,000 Common Shares. The limitations set forth in the
preceding sentence shall be subject to adjustment in accordance with Article 9.

     5.3  EXERCISE PRICE. Each Stock Option Agreement shall specify the Exercise
Price; provided that the Exercise Price under an ISO shall in no event be less
than 100% of the Fair Market Value of a Common Share on the date of grant and
the Exercise Price under an NSO shall in no event be less than 85% of the Fair
Market Value of a Common Share on the date of grant. In the case of an NSO, a
Stock Option Agreement may specify an Exercise Price that varies in accordance
with a predetermined formula while the NSO is outstanding.

     5.4  EXERCISABILITY AND TERM. Each Stock Option Agreement shall specify the
date or event when all or any installment of the Option is to become
exercisable. The Stock Option Agreement shall also specify the term of the
Option; provided that the term of an ISO shall in no event exceed 10 years from
the date of grant. A Stock Option Agreement may provide for accelerated
exercisability in the event of the Optionee's death, disability or retirement or
other events and may provide for expiration prior to the end of its term in the
event of the termination of the Optionee's service.

     5.5  EFFECT OF CHANGE IN CONTROL. Each Option shall become exercisable as
to all or part of the Common Shares subject to such Option in the event that a
Change in Control occurs with respect to the Company, subject to the following
limitations:

          (a)  In the case of an ISO, the acceleration of exercisability shall
     not occur without the Optionee's written consent.

          (b)  If the Company and the other party to the transaction
     constituting a Change in Control agree that such transaction is to be
     treated as a "pooling of interests" for financial reporting purposes, and
     if such transaction in fact is so treated, then the acceleration of
     exercisability shall not occur to the extent that the Company's independent
     accountants and such other party's independent accountants separately
     determine in good faith that such acceleration would preclude the use of
     "pooling of interests" accounting.

     5.6  MODIFICATION OR ASSUMPTION OF OPTIONS. Within the limitations of the
Plan, the Committee may modify, extend or assume outstanding options or may
accept the cancellation of outstanding options (whether granted by the Company
or by another issuer) in return for the grant of new options for the same or a
different number of shares and at the same or a different exercise price. The
foregoing notwithstanding, no modification of an Option shall, without the
consent of the Optionee, alter or impair his or her rights or obligations under
such Option.

     5.7  BUYOUT PROVISIONS. The Committee may at any time (a) offer to buy out
for a payment in cash or cash equivalents an Option previously granted or (b)
authorize an Optionee to

                                       3
<PAGE>

elect to cash out an Option previously granted, in either case at such time and
based upon such terms and conditions as the Committee shall establish.

ARTICLE 6.   PAYMENT FOR OPTION SHARES.

     6.1  GENERAL RULE. The entire Exercise Price of Common Shares issued upon
exercise of Options shall be payable in cash or cash equivalents at the time
when such Common Shares are purchased, except as follows:

          (a) In the case of an ISO granted under the Plan, payment shall be
     made only pursuant to the express provisions of the applicable Stock Option
     Agreement. The Stock Option Agreement may specify that payment may be made
     in any form(s) described in this Article 6.

          (b) In the case of an NSO, the Committee may at any time accept
     payment in any form(s) described in this Article 6.

     6.2  SURRENDER OF STOCK. To the extent that this Section 6.2 is applicable,
all or any part of the Exercise Price may be paid by surrendering, or attesting
to the ownership of, Common Shares that are already owned by the Optionee. Such
Common Shares shall be valued at their Fair Market Value on the date when the
new Common Shares are purchased under the Plan. The Optionee shall not
surrender, or attest to the ownership of, Common Shares in payment of the
Exercise Price if such action would cause the Company to recognize compensation
expense (or additional compensation expense) with respect to the Option for
financial reporting purposes.

     6.3  EXERCISE/SALE. To the extent that this Section 6.3 is applicable, all
or any part of the Exercise Price and any withholding taxes may be paid by
delivering (on a form prescribed by the Company) an irrevocable direction to a
securities broker approved by the Company to sell all or part of the Common
Shares being purchased under the Plan and to deliver all or part of the sales
proceeds to the Company.

     6.4  EXERCISE/PLEDGE. To the extent that this Section 6.4 is applicable,
all or any part of the Exercise Price and any withholding taxes may be paid by
delivering (on a form prescribed by the Company) an irrevocable direction to
pledge all or part of the Common Shares being purchased under the Plan to a
securities broker or lender approved by the Company, as security for a loan, and
to deliver all or part of the loan proceeds to the Company.

     6.5  PROMISSORY NOTE. To the extent that this Section 6.5 is applicable,
all or any part of the Exercise Price and any withholding taxes may be paid by
delivering (on a form prescribed by the Company) a full-recourse promissory
note. However, the par value of the Common Shares being purchased under the
Plan, if newly issued, shall be paid in cash or cash equivalents.

     6.6  OTHER FORMS OF PAYMENT. To the extent that this Section 6.6 is
applicable, all or any part of the Exercise Price and any withholding taxes may
be paid in any other form that is consistent with applicable laws, regulations
and rules.

                                       4

ARTICLE 7.   AUTOMATIC OPTION GRANTS TO OUTSIDE DIRECTORS.

     7.1  INITIAL GRANTS. Each Outside Director who first becomes a member of
the Board after the date of the Company's initial public offering shall receive
a one-time grant of an NSO covering 15,000 Common Shares (subject to adjustment
under Article 9). Such NSO shall be granted on the date when such Outside
Director first joins the Board and shall become exercisable in 36 equal
installments at monthly intervals over the 36-month period commencing on the
date of grant.

     7.2  ANNUAL GRANTS. Upon the conclusion of each regular annual meeting of
the Company's stockholders held in the year 1999 or thereafter, each Outside
Director who will continue serving as a member of the Board thereafter shall
receive an NSO covering 5,000 Common Shares (subject to adjustment under Article
9), except that such NSO shall not be granted in the fiscal year in which the
same Outside Director received the NSO described in Section 7.1. NSOs granted
under this Section 7.2 shall become exercisable in full on the first anniversary
of the date of grant.

     7.3  ACCELERATED EXERCISABILITY. All NSOs granted to an Outside Director
under this Article 7 shall become exercisable in full in the event of:

          (a) The termination of such Outside Director's service because of
     death, total and permanent disability or retirement at or after age 70; or

          (b) A Change in Control with respect to the Company, except as
     provided in the next following sentence. If the Company and the other party
     to the transaction constituting a Change in Control agree that such
     transaction is to be treated as a "pooling of interests" for financial
     reporting purposes, and if such transaction in fact is so treated, then the
     acceleration of exercisability shall not occur to the extent that the
     Company's independent accountants and such other party's independent
     accountants separately determine in good faith that such acceleration would
     preclude the use of "pooling of interests" accounting.

     7.4  EXERCISE PRICE. The Exercise Price under all NSOs granted to an
Outside Director under this Article 7 shall be equal to 100% of the Fair Market
Value of a Common Share on the date of grant, payable in one of the forms
described in Sections 6.1, 6.2, 6.3 and 6.4.

     7.5  TERM. All NSOs granted to an Outside Director under this Article 7
shall terminate on the earliest of (a) the 10th anniversary of the date of
grant, (b) the date three months after the termination of such Outside
Director's service for any reason other than death or total and permanent
disability or (c) the date 12 months after the termination of such Outside
Director's service because of death or total and permanent disability.

     7.6  AFFILIATES OF OUTSIDE DIRECTORS. The Committee may provide that the
NSOs that otherwise would be granted to an Outside Director under this Article 7
shall instead be granted to an affiliate of such Outside Director. Such
affiliate shall then be deemed to be an Outside Director for purposes of the
Plan, provided that the service-related vesting and termination

                                       5
<PAGE>

provisions pertaining to the NSOs shall be applied with regard to the service of
the Outside Director.

ARTICLE 8.   RESTRICTED SHARES.

     8.1  RESTRICTED STOCK AGREEMENT. Each grant of Restricted Shares under the
Plan shall be evidenced by a Restricted Stock Agreement between the recipient
and the Company. Such Restricted Shares shall be subject to all applicable terms
of the Plan and may be subject to any other terms that are not inconsistent with
the Plan. The provisions of the various Restricted Stock Agreements entered into
under the Plan need not be identical.

     8.2  PAYMENT FOR AWARDS. Subject to the following sentence, Restricted
Shares may be sold or awarded under the Plan for such consideration as the
Committee may determine, including (without limitation) cash, cash equivalents,
full-recourse promissory notes, past services and future services. To the extent
that an Award consists of newly issued Restricted Shares, the Award recipient
shall furnish consideration with a value not less than the par value of such
Restricted Shares in the form of cash, cash equivalents or past services
rendered to the Company (or a Parent or Subsidiary), as the Committee may
determine.

     8.3  VESTING CONDITIONS. Each Award of Restricted Shares may or may not be
subject to vesting. Vesting shall occur, in full or in installments, upon
satisfaction of the conditions specified in the Restricted Stock Agreement. A
Restricted Stock Agreement may provide for accelerated vesting in the event of
the Participant's death, disability or retirement or other events. All
Restricted Shares shall become vested in the event that a Change in Control
occurs with respect to the Company, except as provided in the next following
sentence. If the Company and the other party to the transaction constituting a
Change in Control agree that such transaction is to be treated as a "pooling of
interests" for financial reporting purposes, and if such transaction in fact is
so treated, then the acceleration of vesting shall not occur to the extent that
the Company's independent accountants and such other party's independent
accountants separately determine in good faith that such acceleration would
preclude the use of "pooling of interests" accounting.

     8.4  VOTING AND DIVIDEND RIGHTS. The holders of Restricted Shares awarded
under the Plan shall have the same voting, dividend and other rights as the
Company's other stockholders. A Restricted Stock Agreement, however, may require
that the holders of Restricted Shares invest any cash dividends received in
additional Restricted Shares. Such additional Restricted Shares shall be subject
to the same conditions and restrictions as the Award with respect to which the
dividends were paid.

ARTICLE 9.   PROTECTION AGAINST DILUTION.

     9.1  ADJUSTMENTS. In the event of a subdivision of the outstanding Common
Shares, a declaration of a dividend payable in Common Shares, a declaration of a
dividend payable in a form other than Common Shares in an amount that has a
material effect on the price of Common Shares, a combination or consolidation of
the outstanding Common Shares (by reclassification or otherwise) into a lesser
number of Common Shares, a recapitalization, a spin-off or a similar occurrence,
the Committee shall make such adjustments as it, in its sole discretion, deems

                                       6
<PAGE>

appropriate in one or more of (a) the number of Options and Restricted Shares
available for future Awards under Article 3, (b) the limitations set forth in
Section 5.2, (c) the number of NSOs to be granted to Outside Directors under
Article 7; (d) the number of Common Shares covered by each outstanding Option or
(e) the Exercise Price under each outstanding Option. Except as provided in this
Article 9, a Participant shall have no rights by reason of any issue by the
Company of stock of any class or securities convertible into stock of any class,
any subdivision or consolidation of shares of stock of any class, the payment of
any stock dividend or any other increase or decrease in the number of shares of
stock of any class.

     9.2  DISSOLUTION OR LIQUIDATION. To the extent not previously exercised,
Options shall terminate immediately prior to the dissolution or liquidation of
the Company.

     9.3  REORGANIZATIONS. In the event that the Company is a party to a merger
or other reorganization, outstanding Options and Restricted Shares shall be
subject to the agreement of merger or reorganization. Such agreement shall
provide for (a) the continuation of the outstanding Awards by the Company, if
the Company is a surviving corporation, (b) the assumption of the outstanding
Awards by the surviving corporation or its parent or subsidiary, (c) the
substitution by the surviving corporation or its parent or subsidiary of its own
awards for the outstanding Awards, (d) full exercisability or vesting and
accelerated expiration of the outstanding Awards or (e) settlement of the full
value of the outstanding Awards in cash or cash equivalents followed by
cancellation of such Awards.

ARTICLE 10.  DEFERRAL OF DELIVERY OF SHARES

     The Committee (in its sole discretion) may permit or require an Optionee to
have Common Shares that otherwise would be delivered to such Optionee as a
result of the exercise of an Option converted into amounts credited to a
deferred compensation account established for such Optionee by the Committee as
an entry on the Company's books. Such amounts shall be determined by reference
to the Fair Market Value of such Common Shares as of the date when they
otherwise would have been delivered to such Optionee. A deferred compensation
account established under this Article 10 may be credited with interest or other
forms of investment return, as determined by the Committee. An Optionee for whom
such an account is established shall have no rights other than those of a
general creditor of the Company. Such an account shall represent an unfunded and
unsecured obligation of the Company and shall be subject to the terms and
conditions of the applicable agreement between such Optionee and the Company. If
the conversion of Options is permitted or required, the Committee (in its sole
discretion) may establish rules, procedures and forms pertaining to such
conversion, including (without limitation) the settlement of deferred
compensation accounts established under this Article 10.

ARTICLE 11.  AWARDS UNDER OTHER PLANS.

     The Company may grant awards under other plans or programs. Such awards may
be settled in the form of Common Shares issued under this Plan. Such Common
Shares shall be treated for all purposes under the Plan like Restricted Shares
and shall, when issued, reduce the number of Common Shares available under
Article 3.

                                       7
<PAGE>

ARTICLE 12.  LIMITATION ON RIGHTS.

     12.1 RETENTION RIGHTS. Neither the Plan nor any Award granted under the
Plan shall be deemed to give any individual a right to remain an Employee,
Outside Director or Consultant. The Company and its Parents, Subsidiaries and
Affiliates reserve the right to terminate the service of any Employee, Outside
Director or Consultant at any time, with or without cause, subject to applicable
laws, the Company's certificate of incorporation and by-laws and a written
employment agreement (if any).

     12.2 STOCKHOLDERS' RIGHTS. A Participant shall have no dividend rights,
voting rights or other rights as a stockholder with respect to any Common Shares
covered by his or her Award prior to the time when a stock certificate for such
Common Shares is issued or, in the case of an Option, the time when he or she
becomes entitled to receive such Common Shares by filing a notice of exercise
and paying the Exercise Price. No adjustment shall be made for cash dividends or
other rights for which the record date is prior to such time, except as
expressly provided in the Plan.

     12.3 REGULATORY REQUIREMENTS. Any other provision of the Plan
notwithstanding, the obligation of the Company to issue Common Shares under the
Plan shall be subject to all applicable laws, rules and regulations and such
approval by any regulatory body as may be required. The Company reserves the
right to restrict, in whole or in part, the delivery of Common Shares pursuant
to any Award prior to the satisfaction of all legal requirements relating to the
issuance of such Common Shares, to their registration, qualification or listing
or to an exemption from registration, qualification or listing.

ARTICLE 13.  WITHHOLDING TAXES.

     13.1 GENERAL. To the extent required by applicable federal, state, local or
foreign law, a Participant or his or her successor shall make arrangements
satisfactory to the Company for the satisfaction of any withholding tax
obligations that arise in connection with the Plan. The Company shall not be
required to issue any Common Shares or make any cash payment under the Plan
until such obligations are satisfied.

     13.2 SHARE WITHHOLDING. The Committee may permit a Participant to satisfy
all or part of his or her withholding or income tax obligations by having the
Company withhold all or a portion of any Common Shares that otherwise would be
issued to him or her or by surrendering all or a portion of any Common Shares
that he or she previously acquired. Such Common Shares shall be valued at their
Fair Market Value on the date when taxes otherwise would be withheld in cash.

ARTICLE 14.  FUTURE OF THE PLAN.

     14.1 TERM OF THE PLAN. The Plan, as set forth herein, shall become
effective on December 9, 1998. The Plan shall remain in effect until it is
terminated under Section 14.2, except that no ISOs shall be granted on or after
the 10th anniversary of the later of (a) the date when the Board adopted the
Plan or (b) the date when the Board adopted the most recent increase in the
number of Common Shares available under Article 3 which was approved by the
Company's stockholders.

<PAGE>

     14.2 AMENDMENT OR TERMINATION. The Board may, at any time and for any
reason, amend or terminate the Plan. An amendment of the Plan shall be subject
to the approval of the Company's stockholders only to the extent required by
applicable laws, regulations or rules. No Awards shall be granted under the Plan
after the termination thereof. The termination of the Plan, or any amendment
thereof, shall not affect any Award previously granted under the Plan.

                        ABOVENET COMMUNICATIONS, INC. 1997 STOCK PLAN




SECTION 1.     ESTABLISHMENT AND PURPOSE.

        The purpose of the Plan is to offer selected individuals an opportunity
to acquire a proprietary interest in the success of the Company, or to increase
such interest, by purchasing Shares of the Company's Stock. The Plan provides
both for the direct award or sale of Shares and for the grant of Options to
purchase Shares. Options granted under the Plan may include Nonstatutory Options
as well as ISOs intended to qualify under Section 422 of the Code.

        Capitalized terms are defined in Section 12.


SECTION 2.     ADMINISTRATION.

        (a)    COMMITTEES OF THE BOARD OF DIRECTORS.  The Plan may be
administered by one or more Committees. Each Committee shall consist of two or
more members of the Board of Directors who have been appointed by the Board of
Directors. Each Committee shall have such authority and be responsible for such
functions as the Board of Directors has assigned to it. If no Committee has been
appointed, the entire Board of Directors shall administer the Plan. Any
reference to the Board of Directors in the Plan shall be construed as a
reference to the Committee (if any) to whom the Board of Directors has assigned
a particular function.

        (b)    AUTHORITY OF THE BOARD OF DIRECTORS.  Subject to the provisions
of the Plan, the Board of Directors shall have full authority and discretion to
take any actions it deems necessary or advisable for the administration of the
Plan. All decisions, interpretations and other actions of the Board of Directors
shall be final and binding on all Purchasers, all Optionees and all persons
deriving their rights from a Purchaser or Optionee.


SECTION 3.     ELIGIBILITY.

        (a)    GENERAL RULE.  Only Employees, Outside Directors and Consultants
shall be eligible for the grant of Options or the direct award or sale of
Shares. Only Employees shall be eligible for the grant of ISOs.

        (b) TEN-PERCENT SHAREHOLDERS. An individual who owns more than 10% of
the total combined voting power of all classes of outstanding stock of the
Company, its Parent or any of its Subsidiaries shall not be eligible for
designation as an Optionee or Purchaser unless (i) the Exercise Price is at
least 110% of the Fair Market Value of a Share on the date of grant, (ii) the
Purchase Price (if any) is at least 100% of the Fair Market Value of a Share and
(iii) in the case of an ISO, such ISO by its terms is not exercisable after the
expiration of five years from the date of grant. For purposes of this Subsection
(b), in determining stock ownership, the attribution rules of Section 424(d) of
the Code shall be applied.

SECTION 4.     STOCK SUBJECT TO PLAN.

        (a)    BASIC LIMITATION.  The aggregate number of Shares that may be
issued under the Plan (upon exercise of Options or other rights to acquire
Shares) shall not exceed 4,497,696 Shares, subject to adjustment pursuant to
Section 8(1). The number of Shares that are subject to Options or other rights
outstanding at any time under the Plan shall not exceed the number of Shares
that then remain available for issuance under the Plan. The Company, during the
term of the Plan, shall at all times reserve and keep available sufficient
Shares to satisfy the requirements of the Plan.

        (b)    ADDITIONAL SHARES.  In the event that any outstanding Option or
other right for any reason expires or is canceled or otherwise terminated, the
Shares allocable to the unexercised portion of such Option or other right shall
again be available for the purposes of the Plan. In the event that Shares issued
under the Plan are reacquired by the Company pursuant to any forfeiture
provision, right of repurchase or right of first refusal, such Shares shall
again be available for the purposes of the Plan, except that the aggregate
number of Shares which may be issued upon the exercise of ISOs shall in no event
exceed 4,497,696 Shares (subject to adjustment pursuant to Section 8).


SECTION 5.     TERMS AND CONDITIONS OF AWARDS OR SALES.

        (a)    STOCK PURCHASE AGREEMENT.  Each award or sale of Shares under
the Plan (other than upon exercise of an Option) shall be evidenced by a Stock
Purchase Agreement between the Purchaser and the Company. Such award or sale
shall be subject to all applicable terms and conditions of the Plan and may be
subject to any other terms and conditions which are not inconsistent with the
Plan and which the Board of Directors deems appropriate for inclusion in a Stock
Purchase Agreement. The provisions of the various Stock Purchase Agreements
entered into under the Plan need not be identical.

        (b)    DURATION OF OFFERS AND NONTRANSFERABILITY OF RIGHTS.  Any right
to acquire Shares under the Plan (other than an Option) shall automatically
expire if not exercised by the Purchaser within 30 days after the grant of such
right was communicated to the Purchaser by the Company. Such right shall not be
transferable and shall be exercisable only by the Purchaser to whom such right
was granted.

        (c)    PURCHASE PRICE.  The Purchase Price of Shares to be offered under
the Plan shall not be less than 85% of the Fair Market Value of such Shares, and
a higher percentage may be required by Section 3(b). Subject to the preceding
sentence, the Purchase Price shall be determined by the Board of Directors at
its sole discretion. The Purchase Price shall be payable in a form described in
Section 7.

        (d)    WITHHOLDING TAXES.  As a condition to the purchase of Shares, the
Purchaser shall make such arrangements as the Board of Directors may require for
the satisfaction of any

federal, state, local or foreign withholding tax obligations that may arise in
connection with such purchase.

        (e) RESTRICTIONS ON TRANSFER OF SHARES AND MINIMUM VESTING. Any Shares
awarded or sold under the Plan shall be subject to such special forfeiture
conditions, rights of repurchase, rights of first refusal and other transfer
restrictions as the Board of Directors may determine. Such restrictions shall be
set forth in the applicable Stock Purchase Agreement and shall apply in addition
to any restrictions that may apply to holders of Shares generally. In the case
of a Purchaser who is not an officer of the Company, an Outside Director or a
Consultant, any right to repurchase the Purchaser's Shares at the original
Purchase Price (if any) upon termination of the Purchaser's Service shall lapse
at least as rapidly as 20% per year over the five-year period commencing on the
date of the award or sale of the Shares. Any such right may be exercised only
within 90 days after the termination of the Purchaser's Service for cash or for
cancellation of indebtedness incurred in purchasing the Shares.

        (f)    ACCELERATED VESTING.  Unless the applicable Stock Purchase
Agreement provides otherwise, any right to repurchase a Purchaser's Shares at
the original Purchase Price (if any) upon termination of the Purchaser's Service
shall lapse and all of such Shares shall become vested if the Company is subject
to a Change in Control before the Purchaser's Service terminates.


SECTION 6.     TERMS AND CONDITIONS OF OPTIONS.

        (a)    STOCK OPTION AGREEMENT.  Each grant of an Option under the Plan
shall be evidenced by a Stock Option Agreement between the Optionee and the
Company. Such Option shall be subject to all applicable terms and conditions of
the Plan and may be subject to any other terms and conditions which are not
inconsistent with the Plan and which the Board of Directors deems appropriate
for inclusion in a Stock Option Agreement. The provisions of the various Stock
Option Agreements entered into under the Plan need not be identical.

        (b)    NUMBER OF SHARES.  Each Stock Option Agreement shall specify the
number of Shares that are subject to the Option and shall provide for the
adjustment of such number in accordance with Section 8. The Stock Option
Agreement shall also specify whether the Option is an ISO or a Nonstatutory
Option.

        (c)    EXERCISE PRICE.  Each Stock Option Agreement shall specify the
Exercise Price. The Exercise Price of an ISO shall not be less than 100% of the
Fair Market Value of a Share on the date of grant, and a higher percentage may
be required by Section 3(b). The Exercise Price of a Nonstatutory Option shall
not be less than 85% of the Fair Market Value of a Share on the date of grant,
and a higher percentage may be required by Section 3(b). Subject to the
preceding two sentences, the Exercise Price under any Option shall be determined
by the Board of Directors at its sole discretion. The Exercise Price shall be
payable in a form described in Section 7.

        (d)    WITHHOLDING TAXES. As a condition to the exercise of an Option,
the Optionee shall make such arrangements as the Board of Directors may require
for the satisfaction of any federal, state, local or foreign withholding tax
obligations that may arise in connection with such exercise. The Optionee shall
also make such arrangements as the Board of Directors may require


                                       3
<PAGE>

for the satisfaction of any federal, state, local or foreign withholding tax
obligations that may arise in connection with the disposition of Shares acquired
by exercising an Option.

        (e)    EXERCISABILITY.  Each Stock Option Agreement shall specify the
date when all or any installment of the Option is to become exercisable. In the
case of an Optionee who is not an officer of the Company, an Outside Director or
a Consultant, an Option shall become exercisable at least as rapidly as 20% per
year over the five-year period commencing on the date of the grant. Subject to
the preceding sentence, the exercisability provisions of any Stock Option
Agreement shall be determined by the Board of Directors at its sole discretion.

        (f)    ACCELERATED EXERCISABILITY.  Unless the applicable Stock Option
Agreement provides otherwise, all of an Optionee's Options shall become
exercisable in full if the Company is subject to a Change in Control before the
Optionee's Service terminates.

        (g)    BASIC TERM.  The Stock Option Agreement shall specify the term
of the Option. The term shall not exceed 10 years from the date of grant, and a
shorter term may be required by Section 3(b). Subject to the preceding sentence,
the Board of Directors at its sole discretion shall determine when an Option is
to expire.

        (h)    NONTRANSFERABILITY.  No Option shall be transferable by the
Optionee other than by beneficiary designation, will or the laws of descent and
distribution. An Option may be exercised during the lifetime of the Optionee
only by the Optionee or by the Optionee's guardian or legal representative. No
Option or interest therein may be transferred, assigned, pledged or hypothecated
by the Optionee during the Optionee's lifetime, whether by operation of law or
otherwise, or be made subject to execution, attachment or similar process.

        (i)    TERMINATION OF SERVICE (EXCEPT BY DEATH).  If an Optionee's
Service terminates for any reason other than the Optionee's death, then the
Optionee's Options shall expire on the earliest of the following occasions:

               (i)    The expiration date determined pursuant to Subsection

        (g) above;

               (ii)   The date three months after the termination of the
        Optionee's Service for any reason other than Disability, or such later
        date as the Board of Directors may determine; or

               (iii)         The date six months after the termination of the
        Optionee's Service by reason of Disability, or such later date as the
        Board of Directors may determine.

The Optionee may exercise all or part of the Optionee's Options at any time
before the expiration of such Options under the preceding sentence, but only to
the extent that such Options had become exercisable before the Optionee's
Service terminated (or became exercisable as a result of the termination) and
the underlying Shares had vested before the Optionee's Service terminated (or
vested as a result of the termination). The balance of such Options shall lapse
when the Optionee's Service terminates. In the event that the Optionee dies
after the termination of the Optionee's Service but before the expiration of the
Optionee's Options, all or part of such Options may be exercised (prior to
expiration) by the executors or administrators of the Optionee's estate or by
any person who has acquired such Options directly from the Optionee by



                                       4
<PAGE>

beneficiary designation, bequest or inheritance, but only to the extent that
such Options had become exercisable before the Optionee's Service terminated (or
became exercisable as a result of the termination) and the underlying Shares had
vested before the Optionee's Service terminated (or vested as a result of the
termination).

        (j)    LEAVES OF ABSENCE.  For purposes of Subsection (i) above, Service
shall be deemed to continue while the Optionee is on a bona fide leave of
absence, if such leave was approved by the Company in writing and if continued
crediting of Service for this purpose is expressly required by the terms of such
leave or by applicable law (as determined by the Company).

        (k)    DEATH OF OPTIONEE.  If an Optionee dies while the Optionee is in
Service, then the Optionee's Options shall expire on the earlier of the
following dates:

               (i)    The expiration date determined pursuant to Subsection (g)

        above; or

               (ii) The date 12 months after the Optionee's death.

All or part of the Optionee's Options may be exercised at any time before the
expiration of such Options under the preceding sentence by the executors or
administrators of the Optionee's estate or by any person who has acquired such
Options directly from the Optionee by beneficiary designation, bequest or
inheritance, but only to the extent that such Options had become exercisable
before the Optionee's death or became exercisable as a result of the death. The
balance of such Options shall lapse when the Optionee dies.

        (l)    NO RIGHTS AS A SHAREHOLDER.  An Optionee, or a transferee of an
Optionee, shall have no rights as a shareholder with respect to any Shares
covered by the Optionee's Option until such person becomes entitled to receive
such Shares by filing a notice of exercise and paying the Exercise Price
pursuant to the terms of such Option.

        (m) MODIFICATION, EXTENSION AND ASSUMPTION OF OPTIONS. Within the
limitations of the Plan, the Board of Directors may modify, extend or assume
outstanding Options or may accept the cancellation of outstanding Options
(whether granted by the Company or another issuer) in return for the grant of
new Options for the same or a different number of Shares and at the same or a
different Exercise Price. The foregoing notwithstanding, no modification of an
Option shall, without the consent of the Optionee, impair the Optionee's rights
or increase the Optionee's obligations under such Option.

        (n) RESTRICTIONS ON TRANSFER OF SHARES AND MINIMUM VESTING. Any Shares
issued upon exercise of an Option shall be subject to such special forfeiture
conditions, rights of repurchase, rights of first refusal and other transfer
restrictions as the Board of Directors may determine. Such restrictions shall be
set forth in the applicable Stock Option Agreement and shall apply in addition
to any restrictions that may apply to holders of Shares generally. In the case
of an Optionee who is not an officer of the Company, an Outside Director or a
Consultant, any right to repurchase the Optionee's Shares at the original
Exercise Price upon termination of the Optionee's Service shall lapse at least
as rapidly as 20% per year over the five-year period commencing on the date of
the option grant. Any such repurchase right may be exercised only


                                       5
<PAGE>

within 90 days after the termination of the Optionee's Service for cash or for
cancellation of indebtedness incurred in purchasing the Shares.

        (o)    ACCELERATED VESTING.  Unless the applicable Stock Option
Agreement provides otherwise, any right to repurchase an Optionee's Shares at
the original Exercise Price upon termination of the Optionee's Service shall
lapse and all of such Shares shall become vested if the Company is subject to a
Change in Control before the Optionee's Service terminates.


SECTION 7.     PAYMENT FOR SHARES.

        (a)    GENERAL RULE.  The entire Purchase Price or Exercise Price of
Shares issued under the Plan shall be payable in cash or cash equivalents at the
time when such Shares are purchased, except as otherwise provided in this
Section 7.

        (b)    SURRENDER OF STOCK.  To the extent that a Stock Option Agreement
so provides, all or any part of the Exercise Price may be paid by surrendering,
or attesting to the ownership of, Shares that are already owned by the Optionee.
Such Shares shall be surrendered to the Company in good form for transfer and
shall be valued at their Fair Market Value on the date when the Option is
exercised. The Optionee shall not surrender, or attest to the ownership of,
Shares in payment of the Exercise Price if such action would cause the Company
to recognize compensation expense (or additional compensation expense) with
respect to the Option for financial reporting purposes.

        (c)    SERVICES RENDERED.  At the discretion of the Board of Directors,
Shares may be awarded under the Plan in consideration of services rendered to
the Company, a Parent or a Subsidiary prior to the award.

        (d)    PROMISSORY NOTE.  To the extent that a Stock Option Agreement or
Stock Purchase Agreement so provides, all or a portion of the Exercise Price or
Purchase Price (as the case may be) of Shares issued under the Plan may be paid
with a full-recourse promissory note. The Shares shall be pledged as security
for payment of the principal amount of the promissory note and interest thereon.
The interest rate payable under the terms of the promissory note shall not be
less than the minimum rate (if any) required to avoid the imputation of
additional interest under the Code. Subject to the foregoing, the Board of
Directors (at its sole discretion) shall specify the term, interest rate,
amortization requirements (if any) and other provisions of such note.

        (e)    EXERCISE/SALE.  To the extent that a Stock Option Agreement so
provides, and if Stock is publicly traded, payment may be made all or in part by
the delivery (on a form prescribed by the Company) of an irrevocable direction
to a securities broker approved by the Company to sell Shares and to deliver all
or part of the sales proceeds to the Company in payment of all or part of the
Exercise Price and any withholding taxes.

        (f)    EXERCISE/PLEDGE.  To the extent that a Stock Option Agreement so
provides, and if Stock is publicly traded, payment may be made all or in part by
the delivery (on a form prescribed by the Company) of an irrevocable direction
to pledge Shares to a securities broker or lender approved by the Company, as
security for a loan, and to deliver all or part of the loan



                                       6
<PAGE>

proceeds to the Company in payment of all or part of the Exercise Price and any
withholding taxes.


SECTION 8.     ADJUSTMENT OF SHARES.

        (a)    GENERAL. In the event of a subdivision of the outstanding Stock,
a declaration of a dividend payable in Shares, a declaration of an extraordinary
dividend payable in a form other than Shares in an amount that has a material
effect on the Fair Market Value of the Stock, a combination or consolidation of
the outstanding Stock into a lesser number of Shares, a recapitalization, a
spin-off, a reclassification or a similar occurrence, the Board of Directors
shall make appropriate adjustments in one or more of (i) the number of Shares
available for future grants under Section 4, (ii) the number of Shares covered
by each outstanding Option or (iii) the Exercise Price under each outstanding
Option.

        (b)    MERGERS AND CONSOLIDATIONS.  In the event that the Company is a
party to a merger or consolidation, outstanding Options shall be subject to the
agreement of merger or consolidation. Such agreement, without the Optionees'
consent, may provide for:

               (i)    The continuation of such outstanding Options by the
Company (if the Company is the surviving corporation);

               (ii) The assumption of the Plan and such outstanding Options by
the surviving corporation or its parent;

               (iii) The substitution by the surviving corporation or its parent
of options with substantially the same terms for such outstanding Options; or

               (iv) The cancellation of such outstanding Options without payment
of any consideration.

        (c)    RESERVATION OF RIGHTS. Except as provided in this Section 8, an
Optionee or Purchaser shall have no rights by reason of (i) any subdivision or
consolidation of shares of stock of any class, (ii) the payment of any dividend
or (iii) any other increase or decrease in the number of shares of stock of any
class. Any issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall not affect, and
no adjustment by reason thereof shall be made with respect to, the number or
Exercise Price of Shares subject to an Option. The grant of an Option pursuant
to the Plan shall not affect in any way the right or power of the Company to
make adjustments, reclassifications, reorganizations or changes of its capital
or business structure, to merge or consolidate or to dissolve, liquidate, sell
or transfer all or any part of its business or assets.


SECTION 9.     SECURITIES LAW REQUIREMENTS.

        (a)    GENERAL.  Shares shall not be issued under the Plan unless the
issuance and delivery of such Shares comply with (or are exempt from) all
applicable requirements of law, including (without limitation) the Securities
Act of 1933, as amended, the rules and regulations promulgated thereunder, state
securities laws and regulations, and the regulations of any stock exchange or
other securities market on which the Company's securities may then be traded.



                                       7
<PAGE>

        (b)    FINANCIAL REPORTS.  The Company each year shall furnish to
Optionees, Purchasers and shareholders who have received Stock under the Plan
its balance sheet and income statement, unless such Optionees, Purchasers or
shareholders are key Employees whose duties with the Company assure them access
to equivalent information. Such balance sheet and income statement need not be
audited.

SECTION 10.    NO RETENTION RIGHTS.

        Nothing in the Plan or in any right or Option granted under the Plan
shall confer upon the Purchaser or Optionee any right to continue in Service for
any period of specific duration or interfere with or otherwise restrict in any
way the rights of the Company (or any Parent or Subsidiary employing or
retaining the Purchaser or Optionee) or of the Purchaser or Optionee, which
rights are hereby expressly reserved by each, to terminate his or her Service at
any time and for any reason, with or without cause.

        (b)    RIGHT TO AMEND OR TERMINATE THE PLAN.  The Board of Directors may

ISOs, shall be subject to the approval of the Company's shareholders.
Shareholder approval shall not be required for any other amendment of the Plan.

securities, or partly in cash and partly in securities, shall not disqualify a
member of the Committee from serving as an administrator of the Plan.

         The Board shall have the authority to determine, upon review of
relevant information, the Fair Market Value of the Common Stock, subject to the

Committee to administer the Plan. The Board may delegate this authority to the
Committee.

            (d) Committee's Interpretation of the Plan.

         The interpretation and construction by the Committee of any provision

            (b) Ten Percent Shareholders.

         Any Employee who owns Stock possessing more than 10% of the total
combined voting power of all classes of outstanding stock of the Corporation or
any Affiliate shall not be eligible to receive an Option unless:

expiration of five years from the date of grant.

            (c) Stock Ownership.

         For purposes of Paragraph 4(b), in determining stock ownership, an
Employee shall be considered as owning the stock owned, directly or indirectly,
by or for his or her brothers and sisters, spouse, ancestors, and lineal
descendants. Stock owned, directly or indirectly, by or for a corporation,
partnership, estate, or trust shall be considered as being owned proportionately
by or for its shareholders, partners, or beneficiaries, respectively. Stock with
respect to which such Employee or any other person holds an option shall be
disregarded.

            (d) Outstanding Stock.

         For purposes of Section 4(b), the term "outstanding stock" shall
include all stock actually issued and outstanding immediately after the grant of
the Option to the Optionee but shall not include any share for which an Option
is exercisable by any person.

         5. STOCK

            (a) Shares Subject to This Plan.

            (b) Options Not to Exceed Shares Available.

         The number of Shares for which an Option is exercisable at any time
shall not exceed the number of Shares remaining available for issuance under the
Plan. If any Option expires or is terminated, the number of Shares for which
such Option was exercisable may be made exercisable pursuant to other Options
under the Plan. If the Corporation reacquires any Shares pursuant to Sections 11
or 12, hereof, such Shares may again be made exercisable pursuant to an Option.
The limitations established by this Section 5(b) shall be subject to adjustment
in the manner provided in Section 9 hereof upon the occurrence of an event
specified therein.

         6. TERMS AND CONDITIONS OF OPTIONS.

            (a) Stock Option Agreements.

         Options shall be evidenced by written stock option agreements between
the Optionee and the Corporation in such form as the Committee shall from time
to time determine. No Option or purported Option shall be a valid and binding
obligation of the Corporation unless so evidenced in writing.

            (b) Number of Shares.

         Each stock option agreement shall state the number of Shares for which
the Option is exercisable and shall provide for the adjustment thereof in
accordance with Section 9 hereof.

            (c) Vesting.

         An Optionee may not exercise his or her Option for any Shares until the
Option, in regard to such Shares, has vested. Each stock option agreement shall
include a vesting schedule which shall show when the Option becomes exercisable
provided, each Option shall vest at a rate of at least twenty-five percent (25%)
per year over a period of four (4) years. The vesting schedule shall not impose
upon the Corporation or any Affiliate any obligation to retain the Optionee in
its employ or under contract for any period or otherwise change the
employment-at-will status of an Optionee who is an employee of the Corporation
or any Affiliate. The Committee may elect a shorter vesting period for
non-qualified stock option.

            (d) Lapse of Options.

         Each stock option agreement shall state the time or times when the
option covered thereby lapses and becomes unexercisable in part or in full. An
Option shall lapse on the earliest of the following events (unless otherwise
determined by the Committee and reflected in an option agreement):

                (i) The tenth anniversary of the date of granting the Option;

                (ii) The first anniversary of the Optionee's death;

                (iii) The first anniversary of the date the Optionee ceases to
be an Employee due to total and permanent disability, within the meaning of
Section 22(e)(3) of the Code;

                (iv) On the date provided in Section 6(h)(i), unless with
respect to a Nonstatutory Stock Option, the Committee otherwise extends such
period before the applicable expiration date;

                (v) On the date provided in Section 9 for a transaction
described in such Section;



                                       6
<PAGE>

                (vi) The date the Optionee files or has filed against him or her
a petition in bankruptcy; or

                (vii) The expiration date specified in an Optionee's stock
option agreement.

            (e) Exercise Price.

         Each stock option agreement shall state the Exercise Price for the
Shares for which the Option is exercisable. Subject to Section 4(b), the
Exercise Price of an Incentive Stock Option and a Nonstatutory Stock Option
shall, when granted, be not less than 100% and 85% of the Fair Market Value of
the Shares for which the Option is exercisable, respectively, and not less than
the par value of the Shares.

            (f) Medium and Time Of Payment.

         The Purchase Price shall be payable In full in cash upon the exercise
of an Option but the Committee may allow the Optionee to pay the Purchase Price:

                (i) by surrendering Shares in good form for transfer, owned by
the Optionee and having a Fair Market Value on the date of exercise equal to the
Purchase Price;

                (ii) by delivery of a full recourse promissory note ("Note")
made by the Optionee in the amount of the Purchase Price, bearing interest,
compounded semiannually, at a rate not less than the rate determined under
Section 7872 of the Code to insure that no "foregone interests," as defined in
such section, will accrue, together with the delivery of a duly executed
standard form security agreement securing the Note by a pledge of the Shares
purchased; or

                (iii) in any combination of such consideration or such other
consideration and method of payment for the issuance of Shares to the extent
permitted under applicable law as long as the sum of the cash so paid, the Fair
Market Value of the Shares so surrendered, and the amount of any Note equals the
Purchase Price.

         The Committee or a stock option agreement may prescribe requirements
with respect to the exercise of Options, including the submission by the
Optionee of such forms and documents as the Committee may require and, the
delivery by the Optionee of cash sufficient to satisfy applicable withholding
requirements. The Committee may vary the exercise requirements and procedures
from time to time to facilitate, for example, the broker-assisted exercise of
Options.

            (g) Nontransferability of Options.

         During the lifetime of the Optionee, the Option shall be exercisable
only by the Optionee or the Optionee's conservator or legal representative and
shall not be assignable or transferable except pursuant to a qualified domestic
relations order as defined by the Code. In the event of the Optionee's death,
the Option shall not be transferable by the Optionee other than by will or the
laws of descent and distribution.



                                       7
<PAGE>



            (h) Termination of Employment Other than by Death or Disability.

                (i) If an Optionee ceases to be an Employee for any reason other
than his or her death or disability, the Optionee shall have the right, subject
to the provisions of titles Section 6, to exercise any option held by the
Optionee at any time within ninety (90) days after his or her termination of
employment, but not beyond the otherwise applicable term of the Option and only
to the extent that on such date of termination of employment the Optionee's
right to exercise such Option had vested.

                (ii) For purposes of this Section 6(h), the employment
relationship shall be treated as continuing intact while the Optionee is an
active employee of the Corporation or any Affiliate, or is on military leave,
sick leave, or other bona fide leave of absence to be determined in the sole
discretion of the Committee. The preceding sentence notwithstanding, in the case
of an Incentive Stock option, employment shall be deemed to terminate on the
date the Optionee ceases active employment with the Corporation or any
Affiliate, unless the Optionee's reemployment rights are guaranteed by statute
or contract.

            (i) Death of Optionee.

         If an Optionee dies while an Employee, or after ceasing to be an
Employee but during the period while he or she could have exercised an Option
under Section 6(h), any Option granted to the Optionee may be exercised, to the
extent it had vested at the time of death and subject to the Plan, at any time
within 12 months after the Optionee's death, by the executors or administrators
of his or her estate or by any person or persons who acquire the option by will
or the laws of descent and distribution, but not beyond the otherwise applicable
term of the Option.

            (j) Disability of Optionee.

         If an Optionee ceases to be an Employee due to becoming disabled, any
Option granted to the Optionee may be exercised to the extent it had vested at
the time of cessation and, subject to the Plan, at any time within 12 months
after the Optionee's termination of employment, but not beyond the otherwise
applicable term of the option.

            (k) Rights as a Shareholder.

         An Optionee, or a transferee of an Optionee, shall have no rights as a
shareholder of the Corporation with respect to any Shares for which his or her
Option is exercisable until the date of the issuance of a stock certificate for
such Shares. No adjustment shall be made for dividends, ordinary or
extraordinary or whether in currency, securities, or other property,
distributions, or other rights for which the record date is prior to the date
such stock certificate is issued, except as provided in Section 9 hereof.

            (l) Modification, Extension and Renewal of Options.

         Within the limitations of the plan, the Committee may modify, extend or
renew outstanding Options or accept the cancellation of outstanding Options for
the granting of new Options in substitution therefor. Notwithstanding the
preceding sentence, no modification of an





                                       8
<PAGE>

Option shall, without the consent of the Optionee, alter or impair any rights or
obligations under any Option previously granted.

            (m) Other Provisions.

         The stock option agreements authorized under the Plan may contain such
other provisions which are not inconsistent with the terms of the Plan,
including, without limitation, restrictions upon the exercise of the Option, as
the Committee shall deem advisable.

         7. $100,000 PER YEAR LIMITATION ON VESTING OF ISOs.

         To the extent that the Fair Market Value of Shares (determined for each
Share as of the date of grant of the Option covering such Share) subject to
Options granted under this Plan (or any other plan of the Corporation or any
Affiliate) which are designated as Incentive Stock Options and which become
exercisable by an Optionee for the first time during a single calendar year
exceeds $100,000, the Option(s) (or portion thereof) covering such Shares shall
be recharacterized (to the extent of such excess over $100,000) as a
Nonstatutory Stock Option. In determining which Option(s) shall be treated as
Nonstatutory Stock Options under the preceding sentence, the Options shall be
taken into account in the order granted, with the result that a later granted
Option shall be recharacterized as a Nonstatutory Stock Option prior to such
recharacterization of a previously granted Option.

         8. TERM OF PLAN.

         Options may be granted pursuant to the Plan until ten years following
the Effective Date, and all Options which are outstanding on such date shall
remain in effect until they are exercised or expire by their terms. The Plan
shall expire for all purposes on the date 20 years following the Effective Date.

         9. RECAPITALIZATION, TAKEOVERS, AND LIQUIDATIONS.

            (a) Reorganizations.

         The number of Shares covered by the Plan, as provided in Section 5
hereof, and the number of Shares for which each Option is exercisable shall be
proportionately adjusted for any increase or decrease in the number of issued
Shares resulting from the payment of a Common Stock dividend, a stock split, a
reverse stock split or any other event which results in an increase or decrease
in the number of issued Shares effected without receipt of consideration by the
Corporation, and the Exercise Price shall be proportionately increased in the
event the number of Shares subject to such option are decreased and shall be
proportionately decreased in the event the number of Shares subject to such
Option are increased. For the purposes of this paragraph, conversion of any
convertible securities of the Corporation shall not be deemed to have been
"effected without receipt of consideration." Adjustments shall be made by the
Board, whose determination in that respect shall be final, binding and
conclusive. Except as expressly provided herein, no issuance by the Corporation
of shares of stock of any class, or securities convertible into shares of stock
of any class, shall affect, and no adjustment by reason thereof shall be made
with respect to, the number or price of shares of Common Stock subject to an

            (b) Liquidation.

         In the event of the dissolution or liquidation of the Corporation, each
Option shall terminate immediately prior to the consummation of such action. The
Committee shall notify the Optionee not less than thirty (30) days prior to the
proposed consummation of a pending dissolution or liquidation, and the Option
shall be exercisable as to all Shares which are vested prior to expiration until
immediately prior to the consummation of such action.

            (c) Merger.

         In the event of (i) a proposed merger of the Corporation with or into
another corporation, as a result of which the Corporation is not the surviving
corporation and (ii) the Option is not assumed or an equivalent option
substituted by the successor corporation or a parent or subsidiary of the
successor corporation, then in such case each Option shall terminate immediately
prior to the consummation of such transaction. The Committee shall notify the
Optionee not less than fifteen (15) days prior to the proposed consummation of
such transaction, and the Option shall be exercisable as to all Shares which are
vested prior to expiration and until immediately prior to the consummation of
such transaction.

            (d) Determination by Committee.

         All adjustments described in this Section 9 shall be made by the
Committee, whose determination shall be conclusive and binding on all persons.

            (e) Limitation on Rights of Optionee.

         Except as expressly provided in this Section 9, no Optionee shall have
any rights by reason of any payment of any stock dividend, stock split or
reverse stock split or any other increase or decrease in the number of shares of
stock of any class, or by reason of any reorganization, consolidation,
dissolution, liquidation, merger, exchange, split-up or reverse split-up, or
spin-off of assets or stock of another corporation. Any issuance by the
Corporation of Shares, Options or securities convertible into Shares or Options
shall not affect, and no adjustment by reason thereof shall be made with respect
to, the number or Exercise Price of the Shares for which an Option is
exercisable. Notwithstanding the foregoing, if the Corporation shall enter into
a transaction affecting the Corporation's capital stock or distributions to the
holders of its capital stock for which a revision in the terms of each Option is
not required pursuant to this Section 9, the Committee shall have the fight, but
not the obligation, to revise the terms of each option in a manner the
Committee, in its sole discretion, deems fair and reasonable given the
transaction involved. If necessary or appropriate in connection with such
transaction, the Committee may declare that any Option shall terminate as of a
date fixed by the Committee and give each Optionee the fight to exercise his
Option in whole or in part, including exercise as to Shares to which the Option
would not otherwise be exercisable.

            (f) No Restriction on Rights of Corporation.

         The grant of an Option shall not affect or restrict in any way the
right or power of the Corporation to make adjustments, reclassifications,
reorganizations, or changes of its capital





                                       10

or business structure, or to merge or consolidate, or to dissolve, liquidate,
sell, or transfer all or any part of its business or assets.

         10. SECURITIES LAW REQUIREMENTS.

            (a) Legality of Issuance.

         No Share shall be issued upon the exercise of any Option unless and
until the Corporation was determined that:

                (i) The Corporation and the Optionee have taken all actions
required to exempt the issuance of the Shares from the registration requirements
under the Securities Act of 1933, as amended (the "Act"), or the Corporation and
the Optionee shall determine that the registration requirements of the Act do
not apply to such exercise;

                (ii) Any applicable listing requirement of any stock exchange on
which the Common Stock is listed has been satisfied; and

                (iii) Any other applicable provision of state or Federal law has
been satisfied.

            (b) Restrictions on Transfer: Representations of Optionee: Legends.

         Regardless of whether the offering and sale of Shares has been
registered under the Act or has been registered or qualified under the
securities laws of any state, the Corporation may impose restrictions upon the
sale, pledge, or other -transfer of such Shares, including the placement of
appropriate legends on stock certificates, if, in the judgment of the
Corporation and its counsel, such restrictions are necessary or desirable in
order to achieve compliance with the provisions of the Act, the securities laws
of any state, or any other law. If the sale of Shares is not registered under
the Act and the Corporation shall determine that the registration requirements
of the Act apply to such sale, but an exemption is available which requires an
investment representation or other representation, the Optionee shall be
required, as a condition to purchasing Shares by exercise of his or her Option,
to represent that such Shares are being acquired for investment, and not with a
view to the sale or distribution thereof, except in compliance with the Act, and
to make such other representations as are deemed necessary or appropriate by the
Corporation and its counsel. Stock certificates evidencing Shares acquired
pursuant to an unregistered transaction to which the Act applies shall bear a
restrictive legend substantially in the following form and such other
restrictive legends as are required or deemed advisable under the Plan or the
provisions of any applicable law:

         "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT'), OR QUALIFIED UNDER THE
SECURITIES LAWS OF ANY STATE. THESE SHARES HAVE BEEN ACQUIRED FOR INVESTMENT AND
NOT WITH A VIEW TO OR FOR SALE IN CONNECTION WITH ANY DISTRIBUTION THEREOF, AND
MAY NOT BE SOLD, MORTGAGED, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED
WITHOUT AN EFFECTIVE REGISTRATION UNDER THE ACT AND/OR QUALIFICATION UNDER ANY
APPLICABLE STATE SECURITIES LAWS, OR






                                       11
<PAGE>


WITHOUT AN OPINION OF COUNSEL ACCEPTABLE TO THE CORPORATION AND ITS COUNSEL THAT
SUCH REGISTRATION OR QUALIFICATION IS NOT REQUIRED."

         The Corporation shall also place legends on stock certificates
representing its right of repurchase under Section 11 hereof and the right of
first refusal under Section 12 hereof. Any determination by the Corporation and
its counsel in connection with any of the matters set forth in this Section 10
shall be conclusive and binding on all.

            (c) Registration or Qualification of Securities.

         The Corporation may, but shall not be obligated to, register or qualify
the sale of Shares under the Act or any other applicable law. In connection with
any such registration or qualification, the Corporation shall provide each
Optionee with such information required pursuant to all applicable laws and
regulations.

            (d) Exchange of Certificates.

         If, in the opinion of the Corporation and its counsel, any legend
placed on a stock certificate representing Shares sold hereunder is no longer
required, the Optionee or the holder of such certificate shall be entitled to
exchange such certificate for a certificate representing the same number of
Shares but lacking such legend.

         11. RIGHT OF FIRST REFUSAL.

            (a) Right of First Refusal.

         At the Committee's discretion, Shares issued pursuant to the exercise
of an Option may be subject to a requirement that if an Optionee proposes to
sell, pledge, or otherwise transfer any Shares acquired pursuant to exercise of
an Option, or any interest in such Shares, to any person or entity, the
Corporation shall have a right of first refusal (the "Right of First Refusal")
with respect to such Shares. Any Optionee desiring to transfer Shares subject to
the Right of First Refusal shall give a written notice (the "Transfer Notice")
to the Corporation describing fully the proposed transfer, including the number
of Shares proposed to be transferred, the proposed transfer price, and the name
and address of the proposed transferee. The Transfer Notice shall be signed both
by the Optionee and by the proposed transferee and must constitute a binding
commitment of both parties to the transfer of the Shares. The Corporation shall
have the right to purchase the Shares subject to the Transfer Notice on the
terms of the proposal referred to in the Transfer Notice, subject to any change
in such terms permitted under Section 12(a) hereof, by delivery of a notice of
exercise of the Right of First Refusal within 30 days after the date the
Transfer Notice is received by the Corporation. The Corporation's rights under
this Section 12(a) shall be freely assignable, in whole or in part.

            (b) Transfer of Shares.

         If the Corporation fails to exercise the Right of First Refusal within
30 days after the date on which it receives the Transfer Notice, the Optionee
may, not later than six months following receipt of the Transfer Notice by the
Corporation, consummate a transfer of the Shares subject to the Transfer Notice
on the terms and conditions described in the Transfer Notice. Any





                                       12
<PAGE>

proposed transfer on terms and conditions different from those described in the
Transfer Notice, as well as any subsequent proposed transfer by the Optionee,
shall again be subject to the Right of First Refusal and shall again require
compliance with the procedure described in Section 12(a). If the Corporation
exercises its Right of First Refusal, the Optionee shall immediately endorse and
deliver to the Corporation every stock certificate representing the Shares being
purchased, and the Corporation shall then promptly pay the purchase price in
accordance with the terms set forth in the Transfer Notice.

            (c) Repurchase Payment.

         The amount payable to an Optionee pursuant to the Corporation's
exercise of the right of First Refusal shall be paid to the Optionee in
accordance with the terms and conditions of the Transfer Notice or may, at the
election of the Corporation, be paid in full in cash.

            (d) Binding Effect.

         The Corporation's Right of First Refusal shall inure to the benefit of
its successors and assigns and shall be binding upon any transferee of the
Shares, other than a transferee acquiring Shares in a transaction with respect
10 which the Corporation failed to exercise its Right of First Refusal (a "Free
Transferee") or a transferee of a Free Transferee.

            (e) Termination of Right of First Refusal.

         Notwithstanding any other provision of this Section 12, if the Common
Stock is listed on any United States securities exchange or traded on any formal
over-the-counter market in general use in the United States at the time the
Optionee desires to transfer his or her Shares, the Corporation shall no longer
have the Right of First Refusal, and the Optionee shall have no obligation to
comply with this Section 12.

         12. EXERCISE OF UNVESTED OPTIONS.

         The Committee may grant any Optionee the right to exercise any Option
prior to the complete vesting of such Option. Without limiting the generality of
the foregoing, the Committee may provide that if an Option is exercised prior to
having completely vested, the Shares issued upon such exercise shall remain
subject to vesting at the same rate as under the Option so exercised and shall
be subject to a right, but not an obligation, of repurchase by the Corporation
with respect to all unvested Shares if the Optionee ceases to be an Employee for
any reason. For the purposes of facilitating the enforcement of any such right
of repurchase, at the request of the Committee, the Optionee shall enter into
the Joint Escrow Instructions with the Corporation and deliver every certificate
for his or her unvested Shares with a stock power executed in blank by the
Optionee and by the optionee's spouse, if required for transfer.

         13. AMENDMENT OF THE PLAN.

         The Board or the Committee may, from time to time, terminate, suspend
or discontinue the Plan, in whole or in part, or revise or amend it in any
respect whatsoever including, but not limited to, the adoption of any
amendment(s) deemed necessary or advisable to qualify the Options under rules
and regulations promulgated by the Securities and Exchange

Commission with respect to Employees who are subject to the provisions of
Section 15 of the Securities Exchange Act of 1934, as amended, or to correct any
defect or supply any omission or reconcile any inconsistency in the Plan or in
any option granted thereunder, without approval of the shareholders of the
Corporation, but without the approval of the Corporation's shareholders, no such
revision or amendment shall:

                (i) Increase the number of Shares subject to the Plan, other
than any increase pursuant to Section 9;

                (ii) Materially modify the requirements as to eligibility for
participation in the Plan;

                (iii) Materially increase the benefits accruing to Optionees
under the Plan;

                (v) Amend this Section 14 to defeat its purpose.

         No amendment, termination or modification of the Plan shall affect any
Option theretofore granted in any material adverse way without the consent of
the Optionee.

         14. APPLICATION OF FUNDS.

         The proceeds received by the Corporation from the sale of Common Stock
pursuant to the exercise of an Option shall be used for general corporate
purposes.

         15. APPROVAL OF SHAREHOLDERS.

         The Plan shall be subject to approval by the affirmative vote of the
holders of a majority of all classes of the outstanding shares present and
entitled to vote at the first meeting of shareholders of the Corporation
following the adoption of the Plan or by written consent, and in no event later
than one (1) year following the Effective Date. Prior to such approval, Options
may be granted but shall not be exercisable. And amendment described in Section
13 (i) to (iv) shall also be subject to approval by the Corporation's
shareholders.

         16. WITHHOLDING OF TAXES.

         In the event the Corporation or a Affiliate determines that it is
required to withhold federal, state, or local taxes in connection with the
exercise of an Option or the disposition of Shares issued pursuant to the
exercise of an Option, the Optionee or any person succeeding to the rights of
the Optionee, as a condition to such exercise or disposition, may be required to
make arrangements satisfactory to the Corporation or the Affiliate to enable it
to satisfy such withholding requirements.



                                       14
<PAGE>

         17. RIGHTS AS AN EMPLOYEE.

         Neither the Plan nor any Option granted pursuant thereto shall be
construed to give any person the right to remain in the employ of the
Corporation or any Affiliate, or to affect the right of the Corporation or any
Affiliate to terminate such individual's employment at any time with or without
cause. The grant of an Option shall not entitle the Optionee to, or disqualify
the Optionee from, participation in the grant of any other Option under the Plan
or participation in any other benefit plan maintained by the Corporation or any
Affiliate.

         18. DISAVOWAL OF REPRESENTATIONS, UNDERTAKINGS OR CREATION OF IMPLIED
RIGHTS.

         In adopting and maintaining this Plan and granting options hereunder,
neither the Corporation nor any Affiliate makes any representations or
undertakings with respect to the initial qualification or treatment of Options
under federal or state tax or securities laws. The Corporation and each
Affiliate expressly disavows the creation of any rights in Employees, Optionees,
or beneficiaries of any obligations on the part of the Corporation, any
Affiliate or the Committee, except as expressly provided herein.

         19. INSPECTION OF RECORDS.

         Copies of the Plan, records reflecting each Optionee's Option, and any
other documents and records which an Optionee is entitled by law to inspect
shall be open to inspection by the Optionee and his or her duly authorized
representative at the office of the Committee at any reasonable business hour.

         20. INFORMATION TO OPTIONEES.

         Each Optionee shall be provided with such information regarding the
Corporation as the Committee from time to time deems necessary or appropriate;
provided however, that each Optionee shall at all times be provided with such
information as is required to be provided from time to time pursuant to
applicable regulatory requirements, including, but not limited, any applicable
requirements of the Securities and Exchange Commission, the California
Department of Corporations and other state securities agencies.

restrictions may exist on transfer of the shares issued upon exercise of the
Stock Option;

            (c) Optionee understands that the shares issued upon exercise of
this Stock Option, in addition to other restrictions on transfer, must be held
indefinitely unless subsequently registered under the Act, or unless an
exemption from registration is available; that Rule 701 and Rule 144, two
exemptions from registration which may be available, are only available after
the satisfaction of certain conditions and require the presence of a U.S. public
market for such shares; that no certainty exists that a U.S. public market for
the shares will exist, and that otherwise Optionee may have to sell the shares
pursuant to another exemption from registration which exemption may be difficult
to satisfy; and

            (d) The Corporation shall not be under any obligation to issue any
shares upon the exercise of this Stock Option unless and until the Corporation
has determined that:

                (i) it and Optionee have taken all actions required to register
such shares under the Securities Act, or to perfect an exemption from the
registration requirements thereof;

                (ii) any applicable listing requirement of any F stock exchange
on which such shares are listed has been satisfied; and

                (iii) all other applicable provisions of state and federal law
have been satisfied.

         IN WITNESS WHEREOF, each of the parties hereto has executed this Stock
Option Agreement, in the case of the Corporation by its duly authorized officer,
as of the date and year written above.

Dear Ladies and Gentlemen:

                  In connection with the Registration Statement on Form S-8 (the

corporation (the "COMPANY"), with the Securities and Exchange Commission
pursuant to the Securities Act of 1933, as amended (the "ACT"), and the rules
and regulations promulgated thereunder (the "RULES"), we have been requested by
the Company to render our opinion as to the legality of the securities being

to 7,311,962 shares (the

"SHARES") of Class A Common Stock, par value $.01 per share (the "CLASS A COMMON
STOCK"), of the Company, which have been reserved for issuance upon exercise of
options outstanding under the AboveNet Communications Inc. 1998 Stock Incentive
Plan, the AboveNet Communications Inc. 1997 Stock Plan and the AboveNet
Communications Inc. 1996 Stock Option Plan (collectively, the "ABOVENET OPTION
PLANS") that will be assumed by the Company pursuant to an Agreement and Plan of
Merger (the "MERGER AGREEMENT"), dated as of June 22, 1999, as amended, among
the Company, AboveNet Communications Inc., a Delaware corporation ("ABOVENET"),
and Magellan Acquisition, Inc., a Delaware corporation and wholly owned
subsidiary of the Company ("MERGER SUB"), providing for the merger of Merger
Sub with and into AboveNet, with AboveNet as the surviving corporation in the
Merger.
                  In connection with the furnishing of this opinion, we have
examined originals, conformed copies or photocopies, certified or otherwise
identified to our satisfaction, of the following documents (collectively, the
"DOCUMENTS"):
                  1.       the Registration Statement;
                  2.       the Merger Agreement;
                  3.       the AboveNet Option Plans included as Exhibits 4.6,
                           4.7 and 4.8 to the Registration Statement;
                  4.       the Amended and Restated Certificate of Incorporation
                           of the Company, as amended, included as Exhibit 4.1
                           to the

                           Registration Statement and the Amended and Restated
                           By-laws of the Company included as Exhibit 4.2 to the
                           Registration Statement (collectively, the "CHARTER
                           DOCUMENTS"); and
                  5.       the form of certificate for the shares of Class A
                           Common Stock of the Company included as Exhibit 4.3
                           to the Registration Statement.

                  In addition, we have examined those corporate records of the
Company as we have considered appropriate and those other certificates,
agreements and documents as we deemed relevant and necessary as a basis for the
opinion expressed below.

                  In our examination of the documents referred to above, we have
assumed, without independent investigation, (i) the due authorization, execution
and delivery of each of the Documents by each party to them other than the
Company, (ii) the enforceability of the documents reviewed by us against each
party to them other than the Company, (iii) that the Shares will be
substantially issued as described in the Registration Statement, (iv) the
genuineness of all signatures, (v) the authenticity of all documents
submitted to us as originals, (vi) the conformity to the original documents
of all documents submitted to us as certified, photostatic, reproduced or
conformed copies of validly existing agreements or other documents,

(vii) the authenticity of the latter documents, (viii) that the statements
regarding matters of fact in the certificates, records, agreements, instruments
and documents that we examined are accurate and complete, and (ix) the legal
capacity of all individuals who have executed any of the documents which we
examined.

                  In expressing the opinion set forth below, we have relied upon
the factual matters contained in the representations and warranties of the
Company made in the Documents and in certificates of officers of the Company and
upon certificates of public officials.

                  Based on the foregoing, and subject to the stated assumptions,
exceptions and qualifications, we are of the opinion that the Shares have been
duly authorized for issuance and that such Shares, when issued and delivered by
the Company and paid for in accordance with the terms and provisions of the
AboveNet Option Plans, will be validly issued, fully paid and nonassessable.

                  Our opinion expressed above is limited to the laws of the
State of New York, the General Corporation Law of the State of Delaware and the
Federal laws of the United States of America. Our opinion is also rendered only
with respect to the laws and the rules, regulations and orders under those laws
that are currently in effect. Please be advised that no member of this firm is
admitted to practice in the State of Delaware.
