RECITALS

     A.   PFL and Purchaser entered into that certain Agreement for Construction
          and Sale of Conduit  and Dark  Fiber  System on the 31st day of March,
          1999 ("Conduit and Fiber Sale Agreement") for the sale and purchase of
          [ * * * ] and [ * * * ] fibers  or [ * * * ] of the  total  number  of
          fibers pulled  through  PFL's first  conduit (the "Primary  Conduit"),
          whichever   is   greater,   in   PFL's   [  *  *  *  ]   fiber   optic
          telecommunications  system being  developed  and  constructed  between
          Denver, Colorado and Chicago, Illinois (the "System").

     B.   In connection with the  development and  construction of the System by
          PFL,  the  Parties  desire to enter  into this  Agreement  in order to
          establish  certain  restrictions  on the sale, swap or lease of fibers
          pulled   through  the  Primary   Conduit  to  facilitate   the  mutual
          development  of a substantial  customer base for each Party to utilize
          to  efficiently  maximize and increase each Party's  investment in the
          System for a greater financial return, on the terms and conditions set
          forth herein.

         NOW  THEREFORE,   in  consideration  of  the  mutual  covenants  herein
contained,   and  other  good  and  valuable  consideration,   the  receipt  and
sufficiency  whereof  are  hereby  acknowledged,  the  Parties  hereto  agree as
follows:

         All terms not  defined  herein  shall have the meaning set forth in the
Conduit and Fiber Sale Agreement.

1.       OWNERSHIP:
         ----------

         [ * * * ] fibers  or [ * * * ] of the total  number  of  fibers  pulled
         through the Primary Conduit, whichever is greater.

2.       SALES AND MARKETING:
         --------------------

     Both Parties acknowledge and agree that each Party's [ * * * ] fibers, or [
     * * * ] of the total number of fibers pulled through the Primary Conduit as
     the case may be, shall be designated and disposed of as follows:

     (a)  Each Party shall retain exclusive ownership rights in [ * * * ] fibers
          contained in the Primary Conduit for its own use ("Retained  Fibers").
          Subject to the  provisions of Section (e) below,  nothing herein shall
          limit or preclude  the other  Party from  negotiating  a sale,  lease,
          license or grant of any indefeasible right to use fibers (hereinafter,
          a  "Disposition")  or a swap of fibers,  as it relates to each Party's
          exclusive ownership of its Retained Fibers.  Accordingly,  all revenue
          arising from or attributable to either Party's  Disposition or swap of
          its Retained  Fibers shall remain the personal  property of that Party
          and such revenue shall not be shared with the other Party.

     (b)  Each Party agrees to contribute  its  remaining  fibers in the Primary
          Conduit (the "Joint Fibers") for joint marketing purposes as set forth
          in this Agreement (i.e. If the Parties agree to pull a [ * * * ] count
          fiber cable through the Primary Conduit,  each Party retains exclusive
          ownership rights in [ * * * ] fibers each with the remaining [ * * * ]
          to be used for joint  marketing  purposes).  Each Party will undertake
          reasonable  sales and marketing  efforts to make  Dispositions  of the
          Joint Fibers.  All Dispositions shall be made pursuant to an agreement
          in form and content to be mutually agreed to between the Parties prior
          to any Disposition.  Provided that the proposed  Disposition  complies
          with the Minimum  Prices (as defined below) and is for a period of not
          less than  five (5) years  (the  "Minimum  Term"),  and is in form and
          content  mutually  agreed to between the Parties,  then (i) each Party
          will  contribute  [ * * * ] of  the  Joint  Fibers  required  for  the
          Disposition;  and (ii) neither Party will have the right to decline to
          contribute its Joint Fibers to a Disposition.

     (c)  Any other  arrangement,  transfer or  disposition of the Joint Fibers,
          including,  without  limitation,  a swap  involving  Joint  Fibers,  a
          Disposition of Joint Fibers for less than the Minimum Price or Minimum
          Term or not in accordance with an agreement mutually agreed to between
          the  Parties,  a  Disposition  of the Joint Fibers with the benefit of
          optical amplification  equipment,  or a sale of lit telecommunications
          capacity on the Joint Fibers,  shall require the prior written consent
          of both Parties, and absent such consent,  such alternate  disposition
          shall not occur.

     (d)  Any  Disposition of Joint Fibers,  whether agreed to prior to or after
          execution of this  Agreement,  shall be governed by this Agreement and
          shall be in the name of the Party who  originated  and  negotiated the
          Disposition; provided, however, that the

          originating Party include the  non-originating  Party as a named Party
          in the  Disposition  agreement and any press  release  relating to the
          Disposition of the Joint Fibers.  In the case of Dispositions  entered
          into prior to completion of  construction of the subject Joint Fibers,
          the Parties  will take such steps as are  necessary to ensure that the
          benefit of the Disposition accrues to the  non-originating  Party even
          if the  originating  Party  defaults under the Conduit and Fiber Sales
          Agreement  and  the  subject   fibers  are  provided   solely  by  the
          non-originating  Party.  Neither Party shall have the right to receive
          any revenue  from a  Disposition  unless it has timely  fulfilled  its
          payment obligations under the Conduit and Fiber Sale Agreement.

     (e)  Each Party agrees that the other may Dispose of [ * * * ] of its [ * *
          * ] Retained  Fibers in any third  party  fiber  exchange  without the
          other Party's  consent;  provided that any such fiber  exchange  shall
          include a [ * * * ] resale  restriction on the receiving  third party.
          Each Party's remaining [ * * * ] Retained Fibers shall not be Disposed
          of in any  third  party  transaction,  make any  swap of its  Retained
          Fibers  or sell the  Retained  Fibers  with  the  benefit  of  optical
          amplification,  until this  Agreement is terminated as provided for in
          Article  3.  Either  Party  may at any time  and at its sole  cost and
          expense,  light  its  Retained  Fibers  and  sell   telecommunications
          capacity thereon.

     (f)  Each  Party  expressly  agrees  not to  install  any  cable in its own
          conduit or make any  Disposition of its own conduit in any third party
          transaction,  or swap its own conduit,  until the  termination of this
          Agreement pursuant to Article 3.

     (g)  The number of fibers installed in the Primary Conduit,  whether during
          initial  construction  or  thereafter,  shall be subject to the mutual
          agreement of the  Parties.  The  Provisions  of this  paragraph  shall
          survive expiration or termination of this Agreement.

     (h)  Upon  expiration or termination of any  Disposition,  all Joint Fibers
          that  were part of that  Disposition  shall  revert to the Party  that
          owned such fibers and shall be deemed Retained Fibers.

     (i)  Sales,  leases,  grants  of  indefeasible  rights  to use,  and  other
          dispositions of Joint Fibers to an Affiliate (as hereinafter  defined)
          shall not be deemed Dispositions hereunder,  and any Joint Fibers that
          are  the  subject  of  such  arrangement  shall  remain  Joint  Fibers
          notwithstanding such arrangement.

     (j)  The  Disposition  of the Joint  Fibers shall not be made for less than
          the following prices per mile (the "Minimum Prices").

4.       DEFAULT:
         --------

          For the purposes of this  Agreement,  an "Event of Default" is defined
          as follows:

          (a)  Failure of either Party to provide reasonably  competent staff in
               sufficient numbers, and undertake diligent efforts, to adequately
               market  and  sell the  marketable  fibers  under  the  terms  and
               conditions of this Agreement.

          (b)  Material  failure  of either  Party to  perform  its  duties  and

termination shall then exist. If the defaulting Party fails to cure the Event of
Default as set forth  herein,  the  non-defaulting  Party  may,  in its sole and
absolute  discretion,  terminate this Agreement or obtain  specific  performance
from the  defaulting  Party in addition to any other  remedies  available to the
non-defaulting Party at law or in equity.
