recommendations regarding option grants and terms and conditions thereof will be
conclusive.

     4.3.  The Committee will have the sole responsibility for construing and
interpreting the Plan, for establishing and amending any rules and regulations
as it deems necessary or desirable for the proper administration of the Plan,
and for resolving all questions arising under the Plan. Any decision or action
taken by the Committee arising out of or about the construction, administration,
interpretation and effect of the Plan and of its rules and regulations will, to
the extent permitted by law, be within its absolute discretion, except as

secretary, who need not be a member of the Committee, and may make such rules
and regulations for the conduct of its business as it may deem advisable.

     4.5.  No member of the Committee will be liable, in the absence of bad
faith, for any act or omission with respect to his services on the Committee.

reimbursement as Board members pursuant to the Corporation's Bylaws.

     4.6.  The Committee will regularly inform the Board as to its actions with
respect to all Options granted under the Plan and the terms and conditions and

determination of the persons to receive Options, the form, amount and type of

     6.    Terms and Conditions.
           --------------------

     6.1.  Each Option granted under the Plan shall be evidenced by a written
agreement, which shall be subject to the provisions of this Plan and to such
other terms and conditions as the Corporation may deem appropriate.

     6.2.  Each Option agreement shall specify the period for which the Option
thereunder is granted which in no event shall exceed ten years from the date
of the grant for any Option designated by the Committee as an ISO or ten years
and one day from the date of grant for any Option designated by the Committee as
an NQO and shall provide that the Option shall expire at the end of such period.

     6.3.  The exercise price per share shall be determined by the Committee at
the time any Option is granted and, if the Option is an ISO, shall be no less
than one hundred percent (100%) of Fair Market Value of the Common Stock of the
Corporation on the date the Option is granted, as determined by the Committee.

     6.4.  The aggregate Fair Market Value (determined as of the time the Option
is granted) of the Common Stock with respect to which an ISO under this Plan or
any other plan of the Corporation or its Subsidiaries is exercisable for the
first time by an Optionee during any calendar year shall not exceed $100,000.

     6.5.  An Option shall be exercisable at such time or times, and with
respect to such minimum number of shares, as may be determined by the
Corporation at the time of the grant. The Option agreement may require, if so
determined by the Corporation, that no part of the Option may be exercised until
the Optionee shall have remained in the employ of the Corporation or of a
Subsidiary for such period after the date of the Option as the Corporation may
specify.

     6.6.  The Corporation may prescribe the form of legend which shall be
affixed to the stock certificate representing shares to be issued and the shares

agreement restricting the sale or transfer thereof. Such agreements or
restrictions shall be noted on the certificate representing the shares to be
issued.

     6.7.  No Option issued under the Plan shall be transferable by the Optionee
other than by will or the laws of descent and distribution or pursuant to a
qualified domestic relations order as defined by the Code or Title I of the
Employee Retirement Income Security Act, or rules thereunder.

                                                                    WAM!NET Inc.
                                                            Amended and Restated
                                                          1994 Stock Option Plan

     7.   Exercise of Option.
          ------------------

     7.1. Each exercise of an Option granted hereunder, whether in whole or in
part shall be by written notice thereof, delivered to the Secretary of the
Corporation (or such other person as may be designated). The notice shall state
the number of shares with respect to which the Options are being exercised and
shall be accompanied by payment in full for the number of shares so designated.
Shares shall be registered in the name of the Optionee unless the Optionee
otherwise directs in his or her notice of election.

     7.2. Payment shall be made to the Corporation either (i) in cash, including
certified check, bank draft or money order, (ii) at the discretion of the
Corporation, by delivering Common Stock of the Corporation already owned by the
participant, (iii) at the discretion of the Corporation, by delivering a
promissory note, containing such terms and conditions acceptable to the
Corporation, for all or a portion of the purchase price of the shares so
purchased, or a combination of (i), (ii) and (iii). With respect to (ii), the
Fair Market Value of stock so delivered shall be determined as of the date
immediately preceding the date of exercise.

     7.3. Upon notification of the amount due and prior to, or concurrently
with, the delivery to the Optionee of a certificate representing any shares
purchased pursuant to the exercise of an Option, the Optionee shall promptly pay
to the Corporation any amount necessary to satisfy applicable federal, state or
local withholding tax requirements.

     8.   Adjustment of Option Stock. In case the shares issuable upon exercise
          --------------------------
of any Option granted under the Plan at any time outstanding shall be subdivided
into a greater or combined into a lesser number of shares (whether with or
without par value), the number of shares purchasable upon exercise of such
Option immediately prior thereto shall be adjusted so that the Optionee shall
be entitled to receive a number of shares which he or she would have owned or
have been entitled to receive after the happening of such event had such Option
been exercised immediately prior to the happening of such subdivision or
combination or any record date with respect thereto. An adjustment made pursuant
to this paragraph shall become effective immediately after the effective date of
such subdivision or combination retroactive to the record date, if any, for such
subdivision or combination. The option price (as such amount may have
theretofore been adjusted pursuant to the provisions hereof) shall be adjusted
by multiplying the option price immediately prior to the adjustment of the
number of shares purchasable under the Option by a fraction, of which the
numerator shall be the number of shares purchasable upon the exercise of the
Option immediately prior to such adjustment, and of which the denominator shall
be the number of shares so purchasable immediately thereafter. Substituted
shares of stock shall be deemed shares under Section 3 of the Plan.

     9.   Assignments. Any Option granted under this Plan shall be
          -----------
exercisable only by the Optionee to whom granted during his or her lifetime and
shall not be assignable or transferable otherwise than by will or by the laws of
descent and distribution.

                                       5.

 
                                                                    WAM!NET Inc.
                                                            Amended and Restated
                                                          1994 Stock Option Plan

     10.   Severance; Death; Disability. An Option shall terminate, and no 
           ----------------------------
rights thereunder may be exercised, if the person to whom it is granted ceases
to be employed by the Corporation or by a Subsidiary except that:

     10.1. If the employment of the Optionee is terminated by any reason other
than his or her death or disability, the Optionee may at any time within not
more than three months after termination of his or her employment, exercise his
or her Option rights but only to the extent they were exercisable by the
Optionee on the date of termination of his or her employment; provided, however,
that if the employment is terminated as a result of the Optionee's deliberate,
willful or gross misconduct as determined by the Committee, all rights under the
Option shall terminate and expire upon such termination.

     10.2. If the Optionee dies while in the employ of the Corporation or a
Subsidiary, or within not more than three months after termination of his or her
employment, the Optionee's rights under the Option may be exercised at any time
within one year following such death by his or her personal representative or by
the person or persons to whom such rights under the Option shall pass by will or
by the laws of descent and distribution, but only to the extent they were
exercisable by the Optionee on the date of death.

     10.3. If the employment of the Optionee is terminated because of permanent
disability, the Optionee, or his or her legal representative, may at any time
within not more than one year after termination of his or her employment,
exercise his or her Option rights but only to the extent they were exercisable
by the Optionee on the date of termination of his or her employment.

     10.4. Any provision of Sections 10.1, 10.2 and 10.3 to the contrary
notwithstanding, no Option or any right claimed thereby, therein or thereunder
shall be exercisable by anyone after the expiration of the term of the Option.

     10.5. Transfers of employment between the Corporation and a Subsidiary, or
between Subsidiaries, will not constitute termination of employment for purposes
of any Option granted under this Plan. The Committee may specify in the terms
and conditions of an Option whether any authorized leave of absence or absence
for military or government service or for any other reasons will constitute a
termination of employment for purposes of the Option and the Plan.

     11.   Rights of Participants. Neither the participant nor the personal
           ----------------------
representatives, heirs, or legatees of such participant shall be or have any of
the rights or privileges of a shareholder of the Corporation in respect of any
of the shares issuable upon the exercise of an Option granted under this Plan
unless and until certificates representing such shares shall have been issued
and delivered to the participant or to such personal representatives, heirs or
legatees.

     12.   Securities Registration. If any law or regulation of the Securities
           -----------------------
and Exchange Commission or of any other body having jurisdiction shall require
the Corporation or the participant to take any action in connection with the
exercise of an Option, then notwithstanding

                                      6.

 
                                                                    WAM!NET Inc.

                                                          1994 Stock Option Plan

any contrary provision of an Option agreement or this Plan, the date for
exercise of such Option and the delivery of the shares purchased thereunder
shall be deferred until the completion of the necessary action. In the event
that the Corporation shall deem it necessary, the Corporation may condition the
grant or exercise of an Option granted under this Plan upon the receipt of a
satisfactory certificate that the Optionee is acquiring the Option or the shares
obtained by exercise of the Option for investment purposes and not with the view
or intent to resell or otherwise distribute such Option or shares. In such
event, the stock certificate evidencing such shares shall bear a legend
referring to applicable laws restricting transfer of such shares. In the event
that the Corporation shall deem it necessary to register under the Securities
Act of 1933, as amended, or any other applicable statute, any Options or any
shares with respect to which an Option shall have been granted or exercised,
then the participant shall cooperate with the Corporation and take such action
as is necessary to permit registration or qualification of such Options or
shares.

     13.   Duration and Amendment.
           ----------------------

     13.1. There is no express limitation upon the duration of the Plan, except
for the requirement of the Code that all ISO's must be granted within ten years
from the date the Plan is approved by the shareholders.

     13.2. The Board may terminate or may amend the Plan at any time; provided,
however, that the Board may not, without approval of the shareholders of the
Corporation, (i) increase the maximum number of shares as to which Options may
be granted under the Plan, (ii) permit the granting of ISO's at less than 100%
of Fair Market Value at time of grant, (iii) change the class of employees
eligible to receive Options under the Plan, or (iv) permit Directors to receive
options under the Plan other than pursuant to Section 14 hereof; and, provided
further, that the Board may not amend the Plan more than once every six months,
other than to comport with changes in the Code, the Employee Retirement Income
Security Act, or rules thereunder.

     14.   Granting of Options to Non-Employee Directors.
           ---------------------------------------------

     14.1. Non-Employee Directors shall be entitled to receive such Options
under this Plan as may be granted to them from time to time.

     14.2. All Options granted to Non-Employee Directors shall be designated as
NQOs, shall be evidenced by a written option agreement signed by the Corporation
and the Non-Employee Director, and shall be subject to the same terms and
provisions as are then in effect with respect to granting of NQOs to salaried
officers and key employees of the Corporation, except that the Option shall be
exercisable as to all or any part of the shares subject to the Option from the
date the Option is granted, and shall expire on the earliest of (i) twelve
months after the Optionee ceases to be a director (except by death), (ii) one
year after the death of the optionee, or (iii) seven years after the date of

Corporation, and if it is not so approved on or before one year after the date
of adoption of this Plan by the Board, the Plan shall not come into effect, and
any Options granted pursuant to this Plan shall be deemed canceled.

     16.   Conditions of Employment. The granting of an Option to a participant
           ------------------------

to continue the employment of any participant and shall not lessen or affect the
right of the Corporation to terminate the employment of the participant.

           -------------
authority of the Corporation to exercise its corporate rights and powers,
including, by way of illustration and not by way of limitation, the right to
grant options for proper corporate purposes otherwise than under the Plan to any
employee or any other person, firm, corporation, association, or other entity,

purchase, lease, merger, consolidation, or otherwise, of all or any part of the
business and assets of any person, firm, corporation, association, or other
entity.
