In the event any provision of this Warrant Certificate is inconsistent with the provisions of the Agent Incentive Plan, the terms of the Agent Incentive Plan shall govern.

“Securities Act” shall mean the Securities Act of 1933, as amended, or any similar federal statute, and the rules and regulations of the Commission thereunder, all as the same shall be in effect at the time.

“Warrant” shall mean a right represented by this Warrant Certificate to purchase one share of Common Stock.

2.1. Time of Exercise. The Warrants may be exercised if and only if the condition set forth in subsection (a) of this Section 2.1 is satisfied, but then only to the extent such Warrants are vested in accordance with subsection (b) of this Section 2.1.

(a) The Company shall have on file with the Commission a registration statement on an applicable form under the Securities Act which registers the offering and sale of Warrant Shares upon exercise of Warrants and which shall have been declared effective by the Commission and which shall continue to be effective and shall be current as of the time of exercise of the Warrants.

(b) The Warrants shall be exercisable only to the extent they shall have vested in accordance with the Plan and as follows:

3

(c) If the Agent fails to achieve the applicable Revenue Target for New Monthly Commissionable Revenue and then subsequently maintain the revenue level in the manner described above during the period ending no later than the end of the Final Month, then the Agent shall forfeit the right to purchase the Warrant Shares subject to the Warrants with respect to which the vesting requirements of Section 2.1(b) have not been satisfied and any such Warrants shall become null and void. Unvested Warrants shall also be forfeited if the Agent’s status as an appointed sales agent of the Company is terminated for any reason. Nothing herein shall require the Company to continue doing business with the Agent or otherwise to limit the Company’s rights under the applicable Agent Agreement.

2.2. Manner of Exercise. At any time after the Warrants become exercisable as provided in Section 2.1 until 5:00 p.m., New York time, on the Expiration Date, Holder may exercise the Warrants by either (a) paying the Exercise Price in cash for the Warrant Shares it elects to buy, or (b) effecting a “cashless exercise” as described below.

Warrants that are vested and thus exercisable may be exercised by the Agent’s delivery, on any Business Day until the expiration time set forth above, of a written notice of exercise, in the form attached to this Warrant Certificate as Exhibit A (the “Exercise Notice”). The Exercise Notice should be delivered to the Company’s principal office at One PAETEC Plaza, 600 Willowbrook Office Park, Fairport, New York 14450, or such other address as the Company may specify. Such notice shall specify the number of shares of Common Stock with respect to which the Warrants are being exercised and must be accompanied by (i) if the Exercise Price is being paid in cash, payment in full, by certified or bank check payable to the order of the Company, of the Exercise Price of the Warrant Shares for which the Warrants are being exercised plus the amount (if any) of federal and/or other taxes which the Company may, in its judgment, be required to withhold with respect to an award, and (ii) this Warrant Certificate. The minimum number of shares of Common Stock with respect to which Warrants may be exercised at any time shall be the lesser of (x) 100 shares or such lesser number set forth in the applicable Warrant Certificate and (y) the maximum number of shares available for purchase under the Warrant Certificate at the time of exercise.

Upon receipt of all of these items the Company shall deliver or cause to be delivered to Holder a certificate or certificates representing the aggregate number of full Warrant Shares

4

issuable upon such exercise as hereinafter provided (or in the event that the Company elects not to issue certificated stock, such number of uncertificated Warrant Shares shall be registered in the name of such Holder on the Company’s books and records); provided, however, that in the event that Holder elects to effect a “cashless exercise,” the Holder shall be entitled to receive upon exercise a number of Warrant Shares, computed as of the date on which the Company received the Exercise Notice together with this Warrant Certificate, determined by the following formula:

The stock certificate or certificates so delivered or, in the event the Company does not issue certificated stock, the uncertificated shares so issued shall be registered in the name of Holder. The Warrants shall be deemed to have been exercised and such certificate or certificates shall be deemed to have been issued, and Holder shall be deemed to have become a holder of record of such shares for all purposes, as of the date the notice, together with the Exercise Price (if applicable) and this Warrant Certificate, are received by the Company as described above. If the Warrants shall have been exercised in part, the Company shall, at the time of delivery of the certificate or certificates representing the Warrant Shares (or the direct registration system statement in the event the Company does not issue certificated stock), deliver to Holder a new Warrant Certificate evidencing Warrants representing the right of Holder to purchase the remaining Warrant Shares, which new Warrant Certificate shall in all other respects be identical to this Warrant Certificate or, in the sole discretion of the Company, appropriate notation may be made on this Warrant Certificate and the same returned to Holder.

2.3. Fractional Shares. The Company shall not be required to issue a fractional share of Common Stock upon exercise of the Warrants. In lieu of any fraction of a share which Holder would otherwise be entitled to purchase upon exercise, the Company, at its sole discretion, either

5

shall round the fractional share down to the nearest whole share of Common Stock or shall pay cash in an amount equal to the same fraction of the Fair Market Value per share of Common Stock on the date of exercise.

2.4 Expiration Date. Unless extended in writing by the Company in its sole discretion, any vested but unexercised Warrants shall automatically expire at 5:00 p.m., New York time, on the Expiration Date, and this Warrant Certificate shall be of no further force or effect.

From and after the date hereof, the Company shall at all times reserve and keep available for issuance upon the exercise of the Warrants such number of its authorized but unissued shares of Common Stock (or its authorized and issued shares of Common Stock held in treasury) as will be sufficient to permit the exercise in full of the Warrants. All shares of Common Stock which shall be so issuable, when issued upon exercise of the Warrants and payment therefor in accordance with the terms of the Warrants, shall be duly and validly issued and fully paid and nonassessable, and not subject to preemptive rights.

The Exercise Price and the number of shares of Common Stock covered by the Warrants are subject to adjustment from time to time as provided in this Section 4.

(a) If the Company is involved in any Corporate Transaction other than a Corporate Transaction of the type described in Section 4(b), the number and kind of securities issuable upon exercise of Warrants shall be adjusted so that the Holder of the Warrants shall be entitled to receive upon the exercise thereof the number and kind of securities that such Holder would have received pursuant to such Corporate Transaction if the securities subject to such Warrants had been issued immediately prior to the consummation of such Corporate Transaction. For purposes of this Section 4, “Corporate Transaction” means any reorganization, merger, consolidation, sale of all or substantially all of the Company’s assets, or similar transaction. In the event that the Company is not the issuer of the securities that such Holder would have so received pursuant to such Corporate Transaction, provision shall be made in writing in connection with such transaction for the assumption of the Plan and all then-outstanding Warrants by the corporation or entity that is the issuer of such securities. From and after any such assumption, unless the context otherwise requires (as determined by the Board of Directors in good faith), references in the Plan and each outstanding Warrant to the “Company,” “PAETEC” or “PAETEC Holding Corp.” shall be deemed to be references to such issuer, and such references and the other provisions of the Plan and such Warrants shall be interpreted so as to maintain the interests of the Holders intended by the Plan as of the date hereof and by each such Warrant as of its date. Upon each adjustment of the number or kind of securities for which the Warrants are exercisable as provided in this paragraph, the per share Exercise Price payable upon exercise of the Warrants shall be appropriately and proportionately adjusted, as determined by the Board of Directors or the board of directors of such issuer in good faith.

6

(b) In the event of any Corporate Transaction in which the consideration that the Holder of the Warrants would have received pursuant to such Corporate Transaction if the securities subject to the Warrant had been issued immediately prior to such Corporate Transaction is cash or other property that is not securities, all outstanding but unexercised Warrants shall terminate immediately prior to the consummation of such Corporate Transaction. Any exercise of a Warrant during the 15-day period immediately prior to the consummation of any such Corporate Transaction shall be conditioned, at the discretion of the Holder of such Warrant, on the consummation of the Corporate Transaction and shall be effective only immediately before such consummation.

(c) In case the Company shall at any time after the date of this Warrant Certificate (i) effect a distribution payable in shares of Common Stock to all holders of the outstanding Common Stock, (ii) subdivide the outstanding shares of Common Stock, (iii) combine the outstanding shares of Common Stock into a smaller number of shares of Common Stock or (iv) issue any securities of the Company in a reclassification or recapitalization of the Common Stock, then the number and kind of securities issuable upon exercise of the Warrants (commencing on the record date for such distribution or the effective date of such subdivision, combination, reclassification or recapitalization) shall be proportionately adjusted so that the Holder of the Warrants exercised after such time shall be entitled to receive the aggregate number and kind of securities which, if such Warrants had been exercised in full immediately prior to such date, the Holder would have owned upon such exercise and been entitled to receive by virtue of such distribution, subdivision, combination, reclassification or recapitalization. Such adjustment shall be made successively whenever any event listed above shall occur.

(d) Upon each adjustment of the number or kind of shares of Common Stock for which the Warrants are exercisable as provided in Section 4(c) hereof, the per share Exercise Price payable upon exercise of the Warrants shall be adjusted by multiplying the Exercise Price immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of shares of Common Stock covered by the Warrants prior to such adjustment, and (y) the denominator of which shall be the number of shares of Common Stock covered by the Warrants immediately after such adjustment.

Neither this Warrant Certificate nor the rights evidenced hereby may be sold, assigned, transferred, pledged or otherwise disposed of by Holder without the prior written consent of the Company, and any attempted transfer without such prior written consent shall be void.

Upon receipt by the Company from any Holder of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of this Warrant Certificate and indemnity or security reasonably satisfactory to the Company and reimbursement to the Company of all reasonable expenses incidental thereto, and in case of mutilation upon surrender and cancellation of the mutilated Warrant Certificate, the Company will execute and deliver in lieu hereof a new Warrant Certificate of like tenor to such Holder; provided that, in the case of

7

mutilation, no indemnity or security shall be required if this Warrant Certificate in identifiable form is surrendered to the Company for cancellation.

No provision hereof, in the absence of affirmative action by Holder to purchase shares of Common Stock, and no enumeration herein of the rights or privileges of Holder hereof, shall give rise to any liability of such Holder for the Exercise Price of any Warrant Shares or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

Prior to the exercise of the Warrants and the date of the stock certificate representing the Warrant Shares issuable upon exercise (or, in the case of uncertificated stock, the registering of such stock on the Company’s books and records), the Holder of this Warrant Certificate, as such, shall not be entitled to any rights of a stockholder of the Company with respect to, or be deemed for any purpose the holder of, shares for which the Warrants shall be exercisable, including without limitation, the right to vote or to receive dividends or other distributions, and shall not be entitled to receive any notice of any meetings of stockholders of the Company or other proceedings of the Company, except as provided herein.

Any notice, demand, request, consent, approval, declaration, delivery or other communication hereunder to be made pursuant to the provisions of this Warrant Certificate shall be sufficiently given or made if in writing and either delivered in person with receipt acknowledged or sent by registered or certified mail, return receipt requested, postage prepaid, or by a nationally recognized overnight courier or by telecopy and confirmed by telecopy answer back, addressed as follows:

8.3 Amendment. This Warrant Certificate or the Warrants represented hereby may be modified or amended, or the provisions hereof or thereof waived, only with the written consent of the Company and the Holder.
