                                 PAETEC CORP.
               NONQUALIFIED STOCK OPTION AGREEMENT FOR DIRECTOR



Nonqualified Stock Option  This option is not intended to be an incentive stock
                           option under Section 422 of the Internal Revenue Code
                           and will be interpreted accordingly.

Definition of Service      For purpose of this Agreement, "Service" means
                           service as a director of the Company or an affiliate
                           of the Company. Whether a termination of Service
                           shall have occurred for purposes of the Agreement
                           shall be determined by the Board, which determination
                           shall be final, binding and conclusive.

Vesting                    This option is only exercisable before it expires and
                           then only with respect to the vested portion of the
                           option. Subject to the preceding sentence, you may
                           exercise this option, in whole or in part, to
                           purchase a whole number of vested shares not less
                           than 100 shares, unless the number of shares
                           purchased is the total number available for purchase
                           under the option, by following the procedures set
                           forth below.

                           Your right to purchase shares of Stock under this
                           option vests as to 100% of the total number of shares
                           covered by this option, as shown on the cover sheet,
                           on the one-year anniversary of the Vesting Start
                           Date, provided that you have been in Service
                           continuously during the one-year period from the
                           Vesting Start Date through the one-year anniversary
                           of the Vesting Start Date.

                           No additional shares of Stock will vest after your
                           Service has terminated for any reason.

Term                       Your option will expire in any event at the close of
                           business at Company headquarters on the day before
                           the 10th anniversary of the Grant Date, as shown on
                           the cover sheet. Your option will expire earlier if
                           your Service terminates, as described below.

Death                      If your Service terminates because of your death,
                           then your option will expire at the close of business
                           at Company headquarters on the date twelve (12)
                           months after the date of death. During that twelve
                           month period, your estate or heirs may exercise the
                           vested portion of your option.

Leaves of Absence          For purposes of this option, your Service does not
                           terminate when you go on a bona fide leave of
                           absence. The Company determines, in its sole
                           discretion, which leaves count for this purpose, and
                           when your Service terminates for all purposes under
                           this Agreement.

Notice of Exercise         When you wish to exercise this option, you must
                           notify the Company by filing the proper "Notice of
                           Exercise" form at the address given on the form. Your
                           notice must specify how many shares you wish to
                           purchase (in a parcel of at least 100 shares
                           generally). Your notice must also specify how your
                           shares of Stock should be registered (in your name
                           only or in your and your spouse's names as joint
                           tenants with right of survivorship). The notice will
                           be effective when it is received by the Company.

                           If someone else wants to exercise this option after
                           your death, that person must prove to the Company's
                           satisfaction that he or she is entitled to do so.

Form of Payment            When you submit your notice of exercise, you must
                           include payment of the option price for the shares
                           you are purchasing. Payment may be made in one (or a
                           combination) of the following forms:

                           .  Cash, your personal check, a cashier's check, a
                           money order or another cash equivalent acceptable to
                           the Company.

                           .  Shares of Stock which have already been owned by
                           you for more than six months and which are
                           surrendered to the Company. The value of the shares,
                           determined as of the effective date of the option
                           exercise, will be applied to the option price.

                           .   To the extent a public market for the Stock
                           exists as determined by the Company, by delivery (on
                           a form prescribed by the Company) of an irrevocable
                           direction to a licensed securities broker acceptable
                           to the Company to sell Stock and to deliver all or
                           part of the sale proceeds to the Company in payment
                           of the aggregate option price and any withholding
                           taxes.

Transfer of Option         During your lifetime, only you (or, in the event of
                           your legal incapacity or incompetency, your guardian
                           or legal representative) may exercise the option. You
                           cannot transfer or assign this option. For instance,
                           you may not sell this option or use it as security
                           for a loan. If you attempt to do any of these things,
                           this option will immediately become invalid. You may,
                           however, dispose of this option in your will or it
                           may be transferred upon your death by the laws of
                           descent and distribution.

                           Regardless of any marital property settlement
                           agreement, the Company is not obligated to honor a
                           notice of exercise from your spouse, nor is the
                           Company obligated to recognize your spouse's interest
                           in your option in any other way.

Retention Rights           Neither your option nor this Agreement give you the
                           right to be
<PAGE>

                           retained by the Company (or any affiliate of the
                           Company) in any capacity. The Company (and any
                           affiliate of the Company) reserve the right to
                           terminate your Service at any time and for any
                           reason.

Shareholder Rights         You, or your estate or heirs, have no rights as a
                           shareholder of the Company until a certificate for
                           your option's shares has been issued. No adjustments
                           are made for dividends or other rights if the
                           applicable record date occurs before your stock
                           certificate is issued, except as described in this
                           Agreement in the Section entitled "Adjustments."

Adjustments                In the event of a stock split, a stock dividend or a
                           similar change in the Stock, the number of shares
                           covered by this option and the option price per share
                           may be adjusted (and rounded down to the nearest
                           whole number) by the Board as it determines in its
                           sole and absolute discretion. Your option shall be
                           subject to the terms of the agreement of merger,
                           liquidation or reorganization in the event the
                           Company is subject to such corporate activity, which
                           agreement may provide for an earlier expiration of
                           your option.

Applicable Law             This Agreement will be interpreted and enforced under
                           the laws of the State of Delaware, other than any
                           conflicts or choice of law rule or principle that
                           might otherwise refer construction or interpretation
                           of this Agreement to the substantive law of another
                           jurisdiction.

Agreement                  This Agreement constitutes the entire understanding
                           between you and the Company regarding this option.
                           Any prior agreements, commitments or negotiations
                           concerning this option are superseded.

       By signing the cover sheet of this Agreement, you agree to all of the
       terms and conditions described above.
