      7.3.C. As a normal course of technology evolution, Sprint
      will continue to update and upgrade its suite of services.
      Due to this, at some time after December 31, 2007, Sprint
      may choose to substitute other offerings for the Sprint
      Enhanced Frame Relay Service product set.

      Sprint currently offers and will continue to make available
      to customers a substantially similar frame relay service
      that runs over a Sprint IP backbone (currently "SprintLink
      Frame Relay Service"). At any time during this Agreement,
      Customer may elect to purchase and Sprint will provide
      SprintLink Frame Relay Service or other substitute services,
      together with a transition plan, under terms and conditions
      mutually agreeable to Sprint and Customer.

      If Sprint exercises its right to discontinue offering Sprint
      Enhanced Frame Relay Service, this will result in a
      termination of the Sprint Enhanced Frame Relay Service
      portion of this Agreement only and has no impact on other
      services or terms and conditions included in this Agreement.

      Amendment Commencement Date of the Agreement. Customer may
      request two 12-month Renewal Terms with at least 60 days’
      written notice to Sprint before the Initial Term expires.
      Sprint reserves the right to reject the Renewal Terms due to
      the failure of either of the preconditions for such renewal
      set forth in the Agreement by providing written notice of
      such rejection to Customer within 30 days of receiving
      Customer’s request for a Renewal Term. The Renewal Term, if
      any, will include the same terms, conditions, and
      discounting as the Initial Term, except as may be modified
      according to the Agreement. Sprint will not unreasonably
      reject Customer’s request for a Renewal Term, but may do so
      if (a) Customer is in non-compliance with any of the
      material terms or conditions of this Agreement, or (b)
      Sprint no longer generally supports or offers a Product or
      Service (including features or customized service options)
      received by Customer under this Agreement to business

      The Renewal Term of this option will expire on December 31,
      2012. Customer may request up to three 12-month renewal terms
      (each a “Renewal Terms”) with at least 90 days’ written
      notice to Sprint before the Initial Term or a Renewal Term
      expires. Sprint reserves the right to reject the written
      request for a Renewal Term by providing at least 60 days’
      written notice to Customer before the Initial Term or a
      Renewal Term expires. After the Term, Renewal Term, or
      termination of this Agreement, whichever is applicable,
      Customer may, by giving 30 days’ prior written notice to
      Sprint, begin a transition period, the length of which will
      be a commercially reasonable period of time, during which
      Sprint will cooperate with Customer to transition Customer’s
      Network Services to a successor vendor (“Transition Period”);
      provided however, that Sprint will not be obligated to
      cooperate with Customer to transition Customer’s Network
      Services to a successor vendor if Sprint terminates the
      Agreement due to Customer’s failure to cure (i) undisputed
      payment obligations to Sprint within 30 days of receipt of
      written notice of such failure to pay; or (ii) a material
      breach of the Agreement within 30 days of receipt of written
      notice of Customer’s material breach. During the Transition
      Period, Sprint will continue to charge Customer for Network
      Services at the rates and Discounts set forth in this
      Agreement. No Credits or waivers will apply during the
