Subject to other provisions of this Plan, Options may be granted to the same participants on more than one occasion. 5.4.

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 and shall provide that the Option shall expire at the end of such period. 6.3.

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. 4. WAM!NET Inc. 1998 Combined Stock option Plan 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 shall be subject to the provisions of any repurchase agreement or other 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. Each Incentive Stock Option granted hereunder shall not be transferable by the Optionee other than by will or by the laws of descent and distribution, and shall be, during the Optionee's lifetime, exercisable only by the Optionee or Optionee's guardian or legal representative. Each Non-Qualified Stock Option granted hereunder may be transferred by the Optionee for estate planning purposes subject to prior or other written approval by the Committee in its sole discretion or pursuant to any policy and requirements concerning such transfers then in effect as the Committee may in its discretion establish, amend or revoke from time to time; by will or the laws of descent and distribution; or pursuant to a qualified domestic relations order as defined in Section 414 of the Code or Section 206 of the Employee Retirement Income Security Act, or rules thereunder. Except as permitted by the preceding sentences, each Option granted under the Plan and the rights and privileges thereby conferred shall not be transferred, assigned or pledged in any way (whether by operation of law or otherwise), and shall not be subject to execution, attachment or similar process. Any attempt to so transfer, assign, pledge or otherwise dispose of an Option, or of any right or privilege conferred thereby, contrary to the provisions of the Option or the Plan, or any levy of any attachment or similar process upon such rights and privileges, shall be void and unenforceable against the Corporation. 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. 5. WAM!NET Inc. 1998 Combined Stock option Plan 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. Change in Control. ----------------- 9.1. For purposes of this Section 9, a "Change in Control" of the Corporation will mean (i) the sale, lease, exchange or other transfer of substantially all of the assets of the Corporation (in one transaction or in a series of related transactions) to a person or entity that is not controlled, directly or indirectly, by the Corporation, (ii) a merger or consolidation to which the Corporation is a party if the stockholders of the Corporation immediately prior to effective date of such merger or consolidation do not have "beneficial ownership" (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended) immediately following the effective date of such merger or consolidation of more than 80% of the combined voting power of the surviving corporation's outstanding securities ordinarily having the right to vote at elections of directors, or (iii) a change in control of the Corporation of a nature that would be required to be reported pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended, whether or not the Corporation is then subject to such reporting requirements, including, without limitation, such time as (1) any person becomes, after the effective date of the Plan, the "beneficial owner" (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended), directly or indirectly, of 40% or more of the combined voting power of the Corporation's outstanding securities ordinarily having the right to vote at elections of directors, or (2) individuals who constitute the Board of Directors on the effective date of the Plan cease for any reason to constitute at least a majority of the Board, provided that any person becoming a director subsequent to the effective date of the Plan whose election, or nomination for election by the Corporation's stockholders, was approved by a vote of at least a majority of the directors comprising the Board on the effective date of the Plan will, for purposes of this Section 9.1, be considered as though such persons were a member of the Board of Directors on the effective date of the Plan. 9.2. Without limiting the authority of the Committee under Section 4 of the Plan, if a Change in Control of the Corporation occurs, then, if approved by the Committee in its sole 6. WAM!NET Inc. 1998 Combined Stock option Plan discretion either in an agreement evidencing an Option grant at the time of grant or at any time after the grant of an Option, all Options will become immediately exercisable in full and will remain exercisable in accordance with the terms of the Plan; provided, however, that a recipient of Incentive Stock Options may elect that such acceleration of vesting not apply with respect to some or all of the Incentive Stock Options granted to him by so notifying the Committee in writing within three (3) business days of being notified of the Committee's actions pursuant to this Section 9. 9.3. If a Change in Control of the Corporation occurs, then the Committee in its sole discretion either in an agreement evidencing an Option grant at the time of grant or at any time after the grant of an Option, and without the consent of any Option recipient effected thereby, may determine that some or all recipients holding outstanding Options will receive, with respect to and in lieu of some or all of the shares of Option Stock, as of the effective date of any such Change in Control of the Corporation, cash in an amount equal to the excess of the Fair Market Value of such shares either immediately prior to the effective date of such Change in Control of the Corporation or, if greater, determined on the basis of the amount paid as consideration by the other party(ies) to the Change in Control transaction over the exercise price per share of such Options. 9.4. Notwithstanding anything in Section 9.2 or 9.3 of the Plan to the contrary, if the Corporation is then subject to the provisions of Section 280G of the Code, and if the acceleration of the vesting of an Option as provided in Section 9.2 or the payment of cash in exchange for all or part of an Option as provided in Section 9.3 (which acceleration or payment could be deemed a "payment" within the meaning of Section 28OG(b)(2) of the Code), together with any other payments which such recipient has the right to receive from the Corporation or any corporation that is a member of an "affiliated group" (as defined in Section 1504(a) of the Code without regard to Section 1504(b) of the Code) of which the Corporation is a member, would constitute a "parachute payment" (as defined in Section 28OG(b)(2) of the Code), then the payments to such recipient pursuant to Section 9.2 or 9.3 will be reduced to the largest amount as will result in no portion of such payments being subject to the excise tax imposed by Section 4999 of the Code; provided, however, that if such recipient is subject to a separate agreement with the Corporation or a Subsidiary which specifically provides that payments attributable to one or more forms of employee stock incentives or to payments made in lieu of employee stock incentives will not reduce any other payments under such agreement, even if it would constitute an excess parachute payment, then the limitations of this Section 9.4 will, to that extent, not apply. 10. Assignments. Other than as provided in Section 6.7, 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. 11. 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: 7. WAM!NET Inc. 1998 Combined Stock option Plan 11.1. 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. 11.2. 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. 11.3. 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. 11.4. The same exercise periods as provided in Sections 11.1, 11.2 and 11.3 shall also apply with respect to a tranferee of an Option pursuant to Section 6.7, including the extension of the exercise period under Section 11.2 upon the death of the tranferee. 11.5. Any provision of Sections 11.1, 11.2 and 11.3 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. 11.6. 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. 12. 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. 13. 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 any contrary provision of an Option agreement or this Plan, the date for exercise of such Option 8. WAM!NET Inc. 1998 Combined Stock option Plan 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. 14. Duration and Amendment. ---------------------- 14.1. 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. 14.2. 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 15 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. 15. Granting of Options to Non-Employee Directors and Non-Employee -------------------------------------------------------------- Consultants. - ------------ 15.1. Non-Employee Directors and Non-Employee Consultants shall be entitled to receive such Options under this Plan as may be granted to them from time to time. 15.2. All Options granted to Non-Employee Directors and Non-Employee Consultants shall be designated as NQOs, shall be evidenced by a written option agreement signed by the Corporation and the Non-Employee Director or Non- Employee Consultant, 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 Non-Employee Director or a Non-Employee Consultant (except by death), (ii) one year after the death of the optionee, or (iii) seven years after the date of grant. Subject to the foregoing, all provisions of this Plan not inconsistent with the foregoing shall apply to Options granted to Non- Employee Directors, except that Non-Employee Directors shall always have the right to deliver stock in exercise of options as provided in Section 7.2. 9. WAM!NET Inc. 1998 Combined Stock option Plan 16. Approval of Shareholders. This Plan expressly is subject to ------------------------ approval of holders of a majority of the outstanding shares of Common Stock of the 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. 17. Conditions of Employment. The granting of an Option to a ------------------------ participant under this Plan who is an employee shall impose no obligation on the Corporation 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. 18. Other Options. Nothing in the Plan will be construed to limit the ------------- 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, or to grant options to, or assume options of, any person for the acquisition by 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. 19. Governing Law. The provisions of the Plan, including the ------------- provisions and Rules of any Addendum, Appendix, or other document incorporated herein, shall be governed by, interpreted and enforced in accordance with the laws of the State of Minnesota, unless and to the extent they are pre-empted by the laws of the United States of America.

For purposes of this Rule 7, a "Change in ----------------- Control" of the Corporation will mean (i) the sale, lease, exchange or other transfer of substantially all of the assets of the Corporation (in one transaction or in a series of related transactions) to a person or entity that is not controlled, directly or indirectly, by the Corporation, (ii) a merger or consolidation to which the Corporation is a party if the stockholders of the Corporation immediately prior to effective date of such merger or consolidation do not have "beneficial ownership" (as defined in Rule 13d-3 under the United States Securities Exchange Act of 1934, as amended) immediately following the effective date of such merger or consolidation of more than 80% of the combined voting power of the surviving corporation's outstanding securities ordinarily having the right to vote at elections of directors, or (iii) a change in control of the Corporation of a nature that would be required to be reported pursuant to Section 13 or 15(d) of the United States Securities Exchange Act of 1934, as amended, whether or not the Corporation is then subject to such reporting requirements, including, without limitation, such time as (1) any person becomes, after the Adoption Date, the "beneficial owner" (as defined in Rule 13d-3 under the United States Securities Exchange Act of 1934, as amended), directly or indirectly, of 40% or more of the combined voting power of the Corporation's outstanding securities ordinarily having the right to vote at elections of directors, or (2) individuals who constitute the Board on the Adoption Date cease for any reason to constitute at least a majority of the Board, provided that any person becoming a director subsequent to the Adoption Date whose election, or nomination for election by the Corporation's stockholders, was approved by a vote of at least a majority of the directors comprising the Board on the Adoption Date will, for purposes of this Rule 7.1, be considered as though such person was a member of the Board on the Adoption Date. 7.2) If a Change in Control of the Corporation occurs, then each Participant shall be notified by the Committee of whether or not such Change in Control has resulted in the requirements of paragraphs 10 to 14 inclusive of Schedule 9 ceasing to be satisfied and may, subject to Rules 3 and 5, exercise his Option at any time and from time to time within the period of six months following the Change in Control notwithstanding that such exercise may occur within three years of the date on which the Option was granted and at the end of that period all Options, to the extent unexercised, shall lapse. ARTICLE 8. VARIATIONS IN THE SHARE CAPITAL OF THE CORPORATION -------------------------------------------------- 8.1) Variation or Reorganization. If at any time after the date of --------------------------- grant of an Option and before it ceases to be exercisable there is a variation or reorganization of the share capital of the Corporation by virtue of which Shares are subdivided into a greater or combined into a lesser number of shares (whether with or without par value), the number of Shares issuable upon exercise of such Option immediately prior thereto shall be adjusted so that the Participant shall be entitled to receive a number of Shares which he or she would have owned or have been A-8 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 Rule 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 Subscription Price (as such amount may have theretofore been adjusted pursuant to the provisions hereof) shall be adjusted by multiplying the Subscription Price immediately prior to the adjustment of the number of Shares issuable under the Option by a fraction, of which the numerator shall be the number of Shares issuable upon the exercise of the Option immediately prior to such adjustment, and of which the denominator shall be the number of Shares so issuable immediately thereafter. Substituted shares of stock shall be deemed Shares for the purpose of this Scheme. 8.2) In the event of any other variation of the share capital of the Corporation not falling within Rule 8.1, the Subscription Price and/or the number of Shares in respect of which the Option may be exercised shall be adjusted to such extent and in such manner as the Auditors shall in their opinion consider and confirm in writing to the Committee to be fair and reasonable. 8.3) Notwithstanding Rules 8.1 and 8.2, the aggregate Subscription Price payable on the exercise of an Option previously granted hereunder shall not be increased by any adjustment pursuant to Rule 8.1 or Rule 8.2 and any such adjustments shall be subject to prior approval by the Board of Inland Revenue. 8.4) All Participants shall be notified in writing of any such adjustments as soon as practicable thereafter and the Corporation shall be entitled to call in the option certificates for the Options affected by such adjustments for endorsement or replacement, as may appear appropriate. ARTICLE 9. ADMINISTRATION OF THE SCHEME ---------------------------- 9.1) Committee. The Scheme shall in all respects be administered --------- under the direction of a duly authorized Committee of the Board appointed by the Board for that purpose. The Committee may make such rules for the conduct of the Scheme, not being inconsistent with the provisions hereof, as it shall think fit. Any dispute regarding the interpretation of the Scheme or the terms of any Option shall be determined by the Committee in its discretion (after seeking such advice as it shall consider necessary) and its decision shall be final and binding. 9.2) Authorized Share Capital. The Corporation shall at all times ------------------------ maintain an amount of authorized and unissued Shares sufficient to satisfy outstanding Options to subscribe for Shares under the Scheme. 9.3) Notices. Any notice or other communication under or in ------- connection with the Scheme may be given by personal delivery or by sending the same by post, in the case of a company to its registered office or its principal place of business, and in the case of an individual to his last known address, or, where he is a director or an employee of a member of the A-9 Participating Group, either to his last known address or to the address of the place of business at which he performs the whole or substantially the whole of the duties of his office or employment.

The Board shall at any time be entitled to ---------------- amend by resolution all or any of the provisions of the Scheme, provided that: (a) no amendment to the disadvantage of any Participant shall be made unless: (1) the Board shall have invited every such Participant to give an indication as to whether or not he approves the amendment; and (2) the amendment is approved by a majority of those Participants who have given such an indication; (b) no amendment to the advantage of any existing or future Participants shall be made without the prior approval by ordinary resolution of the shareholders of the Company in general meeting (except for minor amendments to benefit the administration of the Scheme, to take account of a change in legislation or to obtain or maintain any favorable tax, exchange-control or regulatory treatment for Participants or for any Participating Company); (c) with the exception of amendments to any conditions attached to any Option pursuant to Rule 3.1, no amendment made to the Scheme shall become effective until it has been approved by the Board of Inland Revenue and nothing shall be done to the Scheme which would prejudice the obtaining of Revenue Approval or cause it to be withdrawn. 10.2) Revenue Approval. The Board may at any time by resolution and ---------------- without other formality amend the Scheme in any way to the extent necessary to secure and maintain Revenue Approval and to ensure that Revenue Approval is not withdrawn pursuant to any statutory modification of the provisions of the Act. 10.3) Notification. On any such amendment being made by the Board all ------------ Participants shall be notified in writing as soon as practicable thereafter. 10.4) Termination. The Board or the Corporation in a general meeting ----------- of the shareholders shall be entitled by resolution to terminate the Scheme at any time but Options previously granted shall continue to be valid and exercisable in accordance with the provisions of the Scheme. A-10 ARTICLE 11. ADDITIONAL PROVISIONS --------------------- 11.1) Conflict. Every Option shall be subject to the condition that -------- no Shares shall be issued to a Participant following the exercise of an Option if such issue would be contrary to any enactment or regulation for the time being in force of the United Kingdom or of any other country having jurisdiction in relation thereto. The Corporation shall not be bound to take any action to obtain the consent of any governmental authority to such issue or to take any action to ensure that any such issue shall be in accordance with any such enactment or regulation if such action could in the opinion of the Committee be unduly onerous. 11.2) Employment. The rights and obligations of any individual under ---------- the terms of his employment with any member of the Group shall not be affected by his participation in the Scheme or any right which he may have to participate in the Scheme or any right which he may have to participate therein, and an individual who participates therein shall waive any and all rights to compensation or damages in consequence of the termination of his office or employment for any reason whatsoever insofar as those rights arise or may arise from his ceasing to have rights under or be entitled to exercise an Option as a result of such termination. 11.3) Auditors. In any matter in which they are required to act -------- hereunder the Auditors shall be deemed to be acting as experts and not as arbitrators.
