This Warrant Certificate certifies that CEDE & CO., or registered assigns, is the registered holder of 200,000 Warrants (the "WARRANTS") to purchase shares of Common Stock, par value $0.01 per share, issuable upon exercise of the Warrants (the "WARRANT SHARES") of PATHNET TELECOMMUNICATIONS, INC., a Delaware 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 April 15, 2008 (the "EXPIRATION DATE"), 3.19 fully paid, registered and non-assessable Warrant Shares, subject to adjustment as provided in Article V of the Supplemental Warrant Agreement, at an exercise price of $0.01 for each share purchased (the "EXERCISE PRICE"); upon surrender of this Warrant Certificate and payment of the Exercise Price (i) in cash or by certified or official bank check, (ii) by a Cashless Exercise or (iii) by any combination of (i) and (ii), at any office or agency maintained for that purpose by the Company (the "WARRANT EXERCISE OFFICE"), subject to the conditions set forth herein and in the Supplemental Warrant Agreement. For purposes of this Warrant, a "CASHLESS EXERCISE" shall mean an exercise of a Warrant in accordance with the immediately following two sentences. To effect a Cashless Exercise, the holder may exercise a Warrant or Warrants without payment of the Exercise Price in cash by surrendering such Warrant or Warrants (represented by one or more Warrant Certificates) and in exchange therefor, receiving such number of shares of Common Stock equal to the product of (1) that number of shares of Common Stock for which such Warrant or Warrants are exercisable and which would be issuable in the event of an exercise with payment of the Exercise Price and (2) the Cashless Exercise Ratio. The "CASHLESS EXERCISE RATIO" shall equal a fraction, the numerator of which is the excess of the Current Market Value (calculated as set forth in this Warrant) per share of Common Stock on the date of exercise over the Exercise Price per share of Common Stock as of the date of exercise and the denominator of which is the Current Market Value per share of Common Stock on the date of 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 holder must specify the number of Warrants for which such Warrant Certificate is to be exercised (without giving effect to the Cashless Exercise). All provisions of the Supplemental Warrant Agreement shall be applicable with respect to a Cashless Exercise of a Warrant Certificate 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 Supplemental Warrant Agreement. "CURRENT MARKET VALUE" per share of Common Stock or any other security at any date means (i) if the security is not registered under the Exchange Act, (a) the value of the security, determined in good faith by the board of directors of the Company and certified in a board resolution, based on the most recently completed arm's-length transaction between the Company and a person other than an Affiliate of the Company and the closing of which occurs on such date or shall have occurred within the six-month period preceding such date, or (b) if no such transaction shall have occurred on such date or within such six-month period or if the board of directors of the Company otherwise elects, the Fair Market Value of the security as determined by a nationally or regionally recognized Independent Financial Expert (as defined herein) (PROVIDED that, in the case of the calculation of Current Market Value for determining the cash value of fractional shares, any such determination within six months that is, in the good faith judgment of the board of directors of the Company, a reasonable determination of value, may be utilized) or (ii) (a) if the security is registered under the Exchange Act, the average of the daily closing sales prices of the securities for the 20 consecutive trading days immediately preceding such date, or (b) if the security has been registered under the Exchange Act for less than 20 consecutive trading days before such date, then the average daily closing sales prices for all of the trading days before such date for which closing sales prices are available, in the case of each of (ii) (a) and (ii) (b), as certified to the Warrant Agent by the President or any vice president or the Chief Financial Officer of the Company. The closing sales price for each such trading day shall be: (A) in the case of a security listed or admitted to trading on any United States national securities exchange or quotation system, 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, (B) in the case of a security not then listed or admitted to trading on any national securities exchange or quotation system, the last reported sale price on such day, or if no sale takes place on such day, the average of the closing bid and asked prices on such day, as reported by a reputable quotation source designated by the Company, (C) in the case of a security not then listed or admitted to trading on any national securities exchange or quotation system and as to which no such reported sale price or bid and asked prices are available, 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, The 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 30 days prior to the date in question) for which prices have been so reported and (D) if there are not bid and asked prices reported during the 30 days prior to the date in question, the Current Market Value shall be determined as if the securities were not registered under the Exchange Act. "EXERCISE EVENT" means, with respect to each Warrant, the date of the occurrence of the earliest of: (i) the time immediately prior to a Change of Control (as such term is defined in the Indenture); (ii)(a) the 180th day (or such earlier date as determined by the Company in its sole discretion) following the closing of an Initial Public Equity Offering (as defined herein) or (b) upon the closing of an Initial Public Equity Offering, but only in respect of Warrants, if any, required to be exercised to permit the holders thereof to sell Warrant Shares pursuant to their respective registration rights, (iii) the time when a class of equity securities of the Company is listed on a national securities exchange or authorized for quotation on the Nasdaq National Market or is otherwise subject to registration under the Exchange Act, or (iv) April 30, 2001. "INDEPENDENT FINANCIAL EXPERT" means a nationally or regionally recognized investment banking or public accounting firm in the United States or, if the Company believes that an investment banking or public accounting firm is generally not qualified to give such an opinion, a nationally recognized appraisal firm, in any case (i) which does not, and whose directors, officers and employees or Affiliates do not, have a direct or indirect material financial interest for its 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. The number of shares of Common Stock issuable upon exercise of the Warrants ("Exercise Rate") is subject to adjustment upon the occurrence of certain events set forth in the Supplemental Warrant Agreement. Any Warrants not exercised on or prior to 5:00 p.m., New York City time, on April 15, 2008 shall thereafter be void. If the Company, in a single transaction or through a series of related transactions, consolidates with or merges with or into, or sells all or substantially all of its property and assets to, another Person (other than a subsidiary of the Company) solely for cash, the holders of Warrants which are then exercisable shall be entitled to receive distributions on the date of such event on an equal basis with holders of shares of Capital Stock (or other securities issuable upon exercise of the Warrants) as if the Warrants had been exercised immediately prior to such event less the aggregate Exercise Price therefor. 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 Supplemental Warrant Agreement. THIS WARRANT CERTIFICATE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. WITNESS the signatures of the duly authorized officers of the Company.
