THIS
      STOCK OPTION AGREEMENT (this “Agreement”), dated as of the Grant Date specified
      above, is entered into by and between RCN Corporation (the “Company”), and the
      Optionee specified above, pursuant to the RCN Corporation 2005 Stock
      Compensation Plan, as in effect and as amended from time to time (the “Plan”);
      and





WHEREAS,
      it has been determined under the Plan that it would be in the best interests
      of
      the Company to grant the non-qualified stock option provided for herein to
      the
      Optionee.





NOW,
      THEREFORE, in consideration of the mutual covenants and premises hereinafter
      set
      forth and for other good and valuable consideration, the parties hereto hereby
      mutually covenant and agree as follows:





**1.** **Incorporation
      By Reference; Plan Document Receipt** **.** This
      Agreement is subject in all respects to the terms and provisions of the Plan
      (including, without limitation, any amendments thereto adopted at any time
      and
      from time to time unless such amendments are expressly intended not to apply
      to
      the grant of the option hereunder), all of which terms and provisions are made
      a
      part of and incorporated in this Agreement as if they were each expressly set
      forth herein. Any capitalized term not defined in this Agreement shall have
      the
      same meaning as is ascribed thereto under the Plan. The Optionee hereby
      acknowledges receipt of a true copy of the Plan and that the Optionee has read
      the Plan carefully and fully understands its content. In the event of any
      conflict between the terms of this Agreement and the terms of the Plan, the
      terms of the Plan shall control.





**2.** **Grant
      of Option** **.** The
      Company hereby grants to the Optionee, as of the Grant Date specified above,
      a
      non-qualified stock option (this “Option”) to acquire from the Company at the
      Per Share Exercise Price specified above the aggregate number of shares of
      the
      Common Stock specified above (the “Option Shares”). This Option is not to be
      treated as (and is not intended to qualify as) an incentive stock option within
      the meaning of Section 422 of the Code.





**3.** **No
      Dividends Equivalents** **.** The
      Optionee shall not be entitled to receive a cash payment in respect of the
      Option Shares underlying this Option on any dividend payment date for the Common

      with the terms set forth on Exhibit A.

      exercisable after the expiration of seven years from the Grant Date (the “Option
      Period”).

      no
      event shall this Option be exercisable for a fractional share of Common
      Stock.

      of Exercise and Payment** **.** This
      Option shall be exercised by the Optionee by delivering to the Secretary of

      Company or his designated agent on any business day (the “Exercise Date”) a
      written notice, in such manner and form as may be required by the Company,
      specifying the number of the Option Shares the Optionee then desires to acquire
      (the “Exercise Notice”). The Exercise Notice shall be accompanied by payment of
      the aggregate Per Share Exercise Price for such number of the Option Shares
      to
      be acquired upon such exercise. Such payment shall be made in the manner set
      forth in Section 6.5 of the Plan.
