               Purchaser's obligation to purchase Dark Fiber is cancelled in its

               With respect to Links 5,18,18A, 26E, 27A and 27C only, Purchaser
               may elect to purchase its Dark Fiber for any such Link(s) from an
               alternate supplier who can provide such Dark Fibers on any such
               Link at a lower price or on an earlier delivery date. AT&T shall
               have the right but not the obligation to match any such bona fide
               offer from an alternate supplier and in the event AT&T does so
               match the bona fide offer, Purchaser shall remain obligated to
               purchase the Dark Fibers on the Link from AT&T at the modified

               fide offer of the alternate supplier, Purchaser shall have the
               option to cancel, in whole or in part, its obligation to purchase
               the Dark Fibers in any such Link without liability to AT&T

11/12/01
<Page>

               AT&T by June 30, 2002 of its intent to exercise its cancellation
               option along with a copy of the bona fide offer from the
               alternate supplier. Any such cancellation notice shall provide
               for a cancellation date no earlier than 30 days before and no
               later than 90 days after the date of the cancellation notice.

3.    For Links 16 and 31 Purchaser may at its option lease from AT&T OC-48
      service in lieu of the fiber purchase from Seattle to Minneapolis. The
      minimum term for this lease will be five (5) calendar years. In order to
      exercise this option Purchaser must notify AT&T that Purchaser wishes to
      enter into such a capacity lease with AT&T no later than December 31st
      2002. The parties shall agree to use good faith efforts to enter into such
      an agreement no later than sixty (60) days thereafter. The price Purchaser
      pays for such service will be the market price in effect from AT&T to
      Purchaser at the time the lease is executed. In the event that Purchaser
      does not so exercise this option, the Purchaser's obligation to purchase
      fiber as described in Exhibit A shall remain in full force and effect.

4.    With respect to Exhibit I, the following words appearing in subparagraph E
      of paragraph 3 are deleted in its entirety; it being understood that
      Purchaser will not have a "take or pay" obligation with respect to rack
      space:

         "Purchaser agrees to reserve a minimum of two additional racks per year
         for a total of eight racks after the first four years. In the event the
         Purchaser fails to make such reservation, Purchaser will pay for the
         space as if Purchaser had made such a reservation."

4A.   For Exhibit I Attachment 1

      Paragraphs B and C are deleted in their entirety and replaced with the
      following paragraphs:

               B.    The monthly Hut License Fee will be $ 700 per month per
                     rack. This Hut License Fee includes a power drain of up to
                     20 AMPS of power per rack with a 40 AMP breaker per rack.
                     See Attachment B for monthly Hut License Fee for each Hut.

               C.    The monthly power fee for any additional power drain above
                     20 AMPS per rack will be charged at a rate of $100 for
                     every additional 10 AMPS of power per rack per month. See
                     Attachment B for the monthly power fee for each Hut. For
                     billing purposes, this power fee will be added to the Hut
                     License Fee. See Attachment B for total monthly Hut License
                     Fee for each Hut.

         emergency restoral from responsible third parties assessed for damages

         Fiber, Conduit or other property.

         7.2.3 C The maintenance fees and maximum labor rate(s) in Article 7.2.3
         A and 7.2.3 B above may be adjusted every two (2) years beginning on

         Statistics (1982-84=100) for the twenty- four (24) month period ending
         three months prior to such anniversary. In the event the Bureau of
         Labor Statistics (or any successor organization) no longer publishes
         the CPI-U, AT&T may designate the statistical index it deems most
         appropriate for adjustments and, from the date the CPI-U ceased to be
         published, such index shall be used to make adjustments under this
         provision. AT&T will confirm such increases to PFN in writing.

7.2.4    TERM. Unless earlier terminated as set forth in this Agreement, this
         Article 7.2 and Exhibit J will be in force for the lesser of the period
         of time that the AT&T System is in use on a reasonably continuous basis
