REGISTERED No. CUSIP U25540 11 0 1,500 WARRANTS WARRANT CERTIFICATE WAM!NET INC. This Warrant Certificate certifies that CEDE & CO., or registered assigns, is the registered holder of 1,500 Warrants (the "Warrants") to purchase shares of Common Stock, par value $0.01 per share (the "Common Stock"), of WAM!NET INC., a Minnesota corporation (the "Company," which term includes its successors and assigns). Each Warrant entitles the holder to purchase from the Company at any time from 9:00 a.m. New York City time on or after the Exercisability Date until 5:00 p.m., New York City time, on March 1, 2005 (the "Expiration Date"), 2.01 fully paid, registered and non-assessable shares of Common Stock, subject to adjustment as provided in Article V of the Warrant Agreement (the "Exercise Rate"), at the exercise price of $0.01 for each share purchased (the "Exercise Price") (the shares of Common Stock purchasable upon exercise of a Warrant being herein referred to as the "Shares" and, unless the context otherwise requires, such term shall also mean all other securities or property purchasable and deliverable upon exercise of a Warrant as provided in the Warrant Agreement), upon surrender of this Warrant 2 Certificate and payment of the Exercise Price (i) in United States dollars or by certified check or official bank check, (ii) pursuant to the next sentence or (iii) in any combination of (i) and (ii), at any office or agency maintained for that purpose by the Company (the "Warrant Agent Office"), subject to the conditions set forth herein and in the Warrant Agreement. In addition to payment by cash or check, a Warrant may be exercised solely by the surrender of the Warrant, and without the payment of the Exercise Price in cash, for such number of Shares equal to the product of (1) the number of Shares for which such Warrant is exercisable with payment of the Exercise Price as in cash of the date of exercise and (2) the Cashless Exercise Ratio. For purposes of this Warrant, the "Cashless Exercise Ratio" shall equal a fraction, the numerator of which is the excess of the Current Market Value per share of the Common Stock on the date of exercise over the Exercise Price per share as of the date of exercise and the denominator of which is the Current Market Value per share of the Common Stock on the date of exercise. An exercise of a Warrant in accordance with the immediately preceding sentences is herein called a "Cashless Exercise." Upon surrender of a Warrant Certificate representing more than one Warrant in connection with the Holder's option to elect a Cashless Exercise, the number of Shares deliverable upon a Cashless Exercise shall be equal to the Cashless Exercise Ratio multiplied by the product of (a) the number of Warrants that the holder specifies is to be exercised pursuant to a Cashless Exercise and (b) the aggregate number of Shares for which such Warrants are then exercisable (without giving effect to the Cashless Exercise option). If the Company has not effected the registration under the Securities Act of the offer and sale of the Shares by the Company to the holders of the Warrants upon the exercise thereof, the Company may elect to require that holders of the Warrants effect the exercise of the Warrants solely pursuant to the Cashless Exercise option and may also amend the Warrants to eliminate the requirements for payment of the Exercise Price with respect tp such Cashless Exercise option. A Warrant may not be exercised in part. All provisions of the Warrant Agreement shall be applicable with respect to an exercise of a Warrant Certificate pursuant to a Cashless Exercise for less than the full number of Warrants represented thereby. Capitalized terms used herein without being defined herein shall have the definitions ascribed to such terms in the Warrant Agreement. This Warrant has initially been issued as part of a unit ("Unit"), each Unit consisting of three Warrants and $1,000 principal amount at maturity of the Company's 13 1/4% Senior Discount Notes due 2005 (the "Notes"). As set forth in the Warrant Agreement and the Indenture, dated as of March 5, 1998 (the "Indenture"), between the Company and First Trust National Association, as Trustee, pursuant to which the Notes have been issued, the Warrants and the Notes will not be separately transferable until the "Separability Date", which means the earliest to occur of: (i) September 1, 1998, (ii) the occurrence of an Exercise Event (as defined herein), (iii) the occurrence of an Event of Default (as defined in the Indenture), (iv) the date on which a registration statement under the Securities Act of 1933, as amended (the "Securities Act"), with respect to a registered exchange offer for the Notes or covering the sale by holders of the Notes is declared effective under the Securities Act, (v) immediately prior to any redemption of Notes by the Company from the net proceeds of an Initial Public Equity Offering (as defined in the Indenture), (vi) immediately prior to the occurrence of a Warrant Change of Control (as defined in the Warrant Agreement) or (v) such earlier date as determined by Merrill Lynch & Co. in its sole discretion. 3 "Current Market Value" per share of Common Stock or any other security at any date of determination means (i) if the security is not traded on a national or regional securities exchange, The Nasdaq Stock Market or in a recognized over-the-counter market (a "Quoted Security"), (a) the fair market value of the security, as determined in good faith by the Board of Directors of the Company and certified in a board resolution delivered to the Warrant Agent, which shall be based on the most recently completed arms-length transaction between the Company and a person other than an Affiliate of the Company, the closing of which shall have occurred within the six-month period preceding such determination, or (b) if no such transaction shall have occurred within such six-month period, the fair market value of the security as determined by a nationally or regionally recognized independent financial expert (provided that, in the case of the calculation of Current Market Value solely for determining the cash value of fractional shares, the last determination of Current Market Value pursuant to this clause (i), if made within the preceding six months, may be utilized), which determination shall be set forth in an officers' certificate delivered to the Warrant Agent, or (ii) (a) if the security is a Quoted Security, the average of the daily closing sales prices of such security for the 20 consecutive trading days immediately preceding such date, or (b) if the security has been a Quoted Security for less than 20 consecutive trading days before such date, then the average of the daily closing sales prices for all of the trading days before such date for which closing sales prices are available. The closing sales price of a security for each such trading day shall be: (A) in the case of a security listed or admitted to trading on any United States national or regional securities exchange or on The Nasdaq Stock Market, the closing sales price, regular way, on such day, or if no sale takes place on such day, the average of the closing bid and asked prices on such day or (B) in the case of a security not then listed or admitted to trading on any national or regional securities exchange or The Nasdaq Stock Market, the average of the closing bid and asked prices on such day, as reported by a reputable quotation source designated by the Company, or in the case of a security as to which no such reported bid and asked prices are available on such day, the average of the reported high bid and low asked prices on such day, as reported by a reputable quotation service, or a newspaper of general circulation in the Borough of Manhattan, City and State of New York, customarily published on each business day, designated by the Company, or, if there shall be no bid and asked prices on such day, the average of the high bid and low asked prices, as so reported, on the most recent day (not more than two days prior to the date in question) for which prices have been so reported; provided, however, that if there are no bid and asked prices reported for such security during such two-day period, Current Market Value shall be determined as if the security were not a Quoted Security. "Exercisability Date" means, with respect to each Warrant, the date as of which both of the following shall have occurred (whether before or on such date): (i) the Separability Date and (ii) an Exercise Event. "Exercise Event" means, with respect to each Warrant, the date of the occurrence of the earliest of: (1) immediately prior to the occurrence of a Warrant Change of Control, (2 )(a) the 90th day (or such earlier date as determined by the Company in its sole discretion) following an Initial Public Equity Offering (as defined in the Warrant Agreement) or (b) upon the closing of the Initial Public Equity Offering but only in respect of Warrants, if any, required to be exercised to 4 permit the holders thereof to sell Shares pursuant to their registration rights, (3) a class of equity securities of the Company is listed on a national securities exchange or authorized for quotation on The Nasdaq Stock Market or is otherwise registered under the Exchange Act, or (4) September 1, 2000. "Independent Financial Expert" means a United States investment banking firm of national or regional standing in the United States (i) which does not, and whose directors and executive officers or Affiliates (as defined in the Warrant Agreement) do not, have a direct or indirect material financial interest for its or their proprietary account in the Company or any of its Affiliates and (ii) which, in the judgment of the Board of Directors of the Company, is otherwise independent with respect to the Company and its Affiliates and qualified to perform the task for which it is to be engaged. The Company has initially designated the principal corporate trust office of the Warrant Agent in the Borough of Manhattan, The City of New York, as the initial Warrant Agent Office. Any Warrants not exercised on or prior to 5:00 p.m., New York City time, on March 1, 2005 shall thereafter be void. If the Company merges, amalgamates or consolidates with or into, or sells all or substantially all of its property and assets to, another Person solely for cash, the holders of Warrants shall be entitled to such cash on the date of consummation of such transaction on an equal basis with holders of Shares (or other securities issuable upon exercise of the Warrants) as if the Warrants had been exercised immediately prior to such event, less the Exercise Price. Upon receipt of such cash the rights of a holder of a Warrant shall terminate and cease and such holder's Warrants shall expire. Reference is hereby made to the further provisions on the reverse hereof which provisions shall for all purposes have the same effect as though fully set forth at this place. This Warrant Certificate shall not be valid unless authenticated by the Warrant Agent, as such term is used in the Warrant Agreement. THIS WARRANT CERTIFICATE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO THE CONFLICT OF LAWS PROVISIONS THEREOF. 5 WITNESS the seal of the Company and signatures of its duly authorized officers.
