               right of way (the "Qwest System Route") and

         B.    Buyer desires to purchase from Qwest and Qwest desires to sell
               to Buyer one (1) conduit and associated improvements within
               the multiple conduit systems constructed by Qwest in the Qwest
               System Route.

         NOW THEREFORE, for and in consideration of the mutual covenants and
agreements herein contained and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereby
agree as follows:

1. Construction and Sale of Conduit. As of the Effective Date of this Agreement,
Qwest agrees to convey to Buyer, and Buyer agrees to purchase from Qwest, one
(1) one and one-quarter-inch (1-1/4") diameter SDR 11 high density polyethylene
(HDPE) conduit (the "Buyer Conduit"), constructed by Qwest, and handholes,
manholes and other ancillary improvements to be constructed by Qwest (the
"Ancillary Facilities"), as described in those certain specifications attached
hereto as Exhibit B and incorporated herein by this reference (the
"Specifications").

         On execution of this Agreement by both parties, Qwest shall convey good
and clear title to the Buyer Conduit, free and clear of all liens and
encumbrances, to Buyer. Transfer of title shall be evidenced by a bill of sale
substantially in the form attached hereto as Exhibit E.

2. Services.

         2.1 The term "Services", as used in this Agreement, shall mean any
physical activity or contact with the rights of way or conduit in the Qwest
System Route involved in the preparation of installation of fiber cable by
Buyer, or by Qwest at the request of Buyer, including, but not limited to, the
placing of handholes or manholes, the pulling of fiber cable, the testing of
fibers, the construction of Ancillary Facilities, and the rodding and roping of
conduit.

         2.2 Qwest will install handholes or manholes at standard intervals

<PAGE>   4

standard interval means a minimum of one handhole or manhole approximately every
5000 feet in the general vicinity of existing Qwest handholes or manholes.

         2.3 Provided that Buyer gives Qwest notice of additional requirements
prior to the completion of the construction of the standard handholes or
manholes, Qwest will install additional Ancillary Facilities at such other
locations as requested by Buyer, at Buyer's expense, subject to the underlying
rights requirements and subject to approval by the permitting agency, and
provided that such installation does not materially interfere with Qwest's
existing facilities.

         In addition, provided that Buyer gives Qwest notice of additional
requirements prior to the completion of the construction, Qwest shall install,
splice and test a single fiber optic cable within the Buyer Conduit and
Ancillary Facilities in accordance with the fiber specifications attached hereto
as Exhibit F. The cable will be supplied to Qwest by Buyer at Buyer's sole cost
and expense and in accordance with delivery terms to be agreed to between the
parties. Buyer shall retain title to the fiber optic cable.

         The charge to Buyer for such additional Services shall be as follows:

         Pulling of fiber           $.87 per foot
         Splicing of fiber          $70.00 per fiber

required for its use of the Buyer Conduit and Ancillary Facilities. A right of
way fee is payable to the Railroad by Qwest by reason of this transaction by the
terms of that certain Letter Agreement dated March 1, 1995 between Qwest and the

                                    EXHIBIT B

                      Standard Construction Specifications

1.0      General.

         The intent of this document is to outline the specifications for
         construction of a fiber optic cable system. In all cases, the standards
         contained in this document or the standards of the federal, state,
         local or private agency having jurisdiction, whichever is stricter,
         shall be followed.

2.0      Material.

         Steel or PVC conduit shall be minimum schedule 40 wall thickness.

         Any exposed steel conduit, brackets or hardware (i.e., bridge
         attachments) shall be hot-dipped galvanized after fabrication.

         Handholes shall have a minimum load rating of H-20 with sufficient soil
         cover.

         Manholes shall have a minimum H-20 loading rating.

         Buried cable warning tape shall be 3 inches wide and display "Warning:
         Buried Fiber Optic Cable," Qwest, and local and emergency One Call
         "800" numbers repeated every 24 inches.

         Fiber optic cable shall be single armored, unless prohibited by the ROW
         Owner, or by codes, laws or regulations.

         EMS markers will be fabricated in the lids of handholes.

3.0      Minimum Depths.

         (a) Minimum cover required in the placement of conduit shall be 42
         inches, except where field conditions dictate otherwise.

         (b) At locations where conduit crosses other subsurface utilities or
         other structures, the conduit shall be installed to provide adequate
         vertical clearance and the applicable minimum depth can be maintained;
         otherwise the conduit will be installed under the existing utility or
         other structure. If, however, adequate clearance cannot be obtained and
         the conduit must be placed above, the cable shall be encased in steel
         pipe and HDPE conduit.

                                   Page 1 of 4
<PAGE>   16

         (c)   In rock, the conduit depth shall be:
               36"-42" in HDPE,
               24"-36" in IIDPE encased in steel,
               18"-24" in HDPE or PVC or steel and concrete encased.

         PVC or HDPE conduit will be backfilled with 6 inches of select
         materials (padding) in rock areas. MDI Polyurethane channel
         (Fiber-Rockgard by Chempro, Inc. or equivalent) may be used as
         protective cover in lieu of select material padding.

         (d) In the case of the use/conversion of existing steel pipelines or
         existing conduit systems, the existing depth shall be considered
         adequate.

4.0      Buried Cable Warning Tape.

         All conduits will be installed with buried cable warning tape except
         where existing steel pipelines or existing conduit systems are used.
         The warning tape shall generally be placed directly above the conduit.

5.0      Conduit Construction.

         Conduits may be placed by means of trenching, plowing, jack and bore,
         push-pull method, or directional bore. Conduits will generally be
         placed on a level grade parallel to the surface, with only gradual
         changes in grade elevation.

         Steel conduit will be joined with threaded collars or welding.

         Conduit crossings of roads maintained by government bodies and railroad
         crossings will be encased in steel conduit, except where the cable is
         placed with 10 feet or more of cover. In the latter case, HDPE is
         adequate.

         Conduit placed by the push-pull method (that is, using a push rod,
         followed by pulling conduit) may use HDPE, PVC, or steel conduit.

         All directional bores will use HDPE or steel conduit.

         All conduits placed on bridges shall have expansion joints placed at
         each structural (bridge) expansion joint or at least every 300 feet,
         whichever is the shorter distance. For bridges under 100 feet, with no
         bridge expansion joint, no conduit expansion joint is required. For
         bridges greater than 100 feet, at least one conduit expansion joint
         will be placed, even if there is no bridge expansion joint.

                                   Page 2 of 4

<PAGE>   17

6.0      Innerduct Installation.

         Innerduct(s) shall be installed in all steel conduits. No cable will be
         placed directly in any split/solid steel conduit without innerduct.

         Innerduct(s) shall extend beyond the end of all conduits a minimum of
         18 inches.

7.0      Cable Installation.

         The fiber optic cable shall be installed using a powered pulling winch
         and hydraulic-powered assist pulling wheels. The maximum pulling force
         to be applied to the fiber optic cable shall be not exceed manufactures
         recommendations.

         All splices will be contained in a handhole or manhole.

8.0      Cable Markers (Warning Signs).

         Cable markers shall be installed at sufficient frequency to mark the
         location of the cable. Markers shall be positioned so that they can be
         seen from the location of the cable and generally set facing
         perpendicular to the cable running line.

9.0      Compliance.

         All work will be done in strict accordance with federal, state, local
         and applicable private rules and laws regarding safety and
         environmental issues, including those set forth by OSHA and the EPA. In
         addition, all work and the resulting fiber system will comply with the
         current requirements of all governing entities (FCC, NEC, DEC, and
         other national, state, and local codes).

10.0     As Built Drawings.

         As-built drawings will contain a minimum of the following:

              1) Information showing the location of running line, relative
              to permanent landmarks, including but not limited to, railroad
              mileposts, boundary crossings and utility crossings.

              2) Splice locations

              3) Manhole and handhole locations

              4) Conduit information (type, length, expansion joints, etc.)

                                   Page 3 of 6
<PAGE>   22

hereof shall be the fair market value of such Right of Occupancy, as determined
by the parties as of the date of exercise of such extension, as follows:

(a)   Grantee and Grantor shall attempt, in good faith within forty-five (45)
      days after Grantor's receipt of Grantee's renewal notice, to reach an
      agreement on the fair market value of the renewal rights with respect to
      the Right-of-Occupancy. If Grantor and Grantee do not reach agreement on
      the fair market value within the forty-five (45) day period, then at the
      end of that forty-five (45) day period, Grantee may deposit cash in escrow
      with a title insurance company (to be named) in an amount equally between
      the proposed positions of Grantee and Grantor as to the fair market value
      of such longitudinal renewal rights.

(b)   After the forty-five (45) day period, Grantee and Grantor shall each
      appoint an employee (who shall have at least five (5) years of full-time
      experience in the valuation of utility easements) or employ/appoint an
      appraiser, who shall be a member of the American Institute of Real Estate
      Appraisers of that state (MAI) and who shall have at least five (5) years
      of full-time commercial appraisal experience, to determine the fair market
      value of the renewal rights with respect to such Right-of-Occupancy, and,
      within fifteen (15) days after the expiration of such forty-five (45) day
      period, shall notify the other party of the person so appointed. The two
      appointees (whether employees or appraisers) shall meet promptly and
      attempt to agree on such fair market value.

(c)   In the event one party fails to give the other party notice within such
      fifteen (15) day period, identifying a person so appointed, the person
      designated by the non-failing party shall independently determine the fair
      market value of the Right-of-Occupancy rights hereunder with respect to
      such renewal period.

(d)   If the two appointees are unable to agree within twenty (20) days after
      the last of them has been appointed, they shall attempt to agree upon and
      designate an outside appraiser (the "Appraiser"), not an employee of
      either party, meeting the MAI and five (5) year experience qualifications
      above, within ten (10) days after the expiration of the twenty (20) days
      during which the two appointees were given to agree. If the appointees are
      unable to agree on the Appraiser, either of the parties, after giving five
      (5) days' notice to the other, may apply to (i) the presiding judge of the
      Federal District Court of State or County(ies) where the Right-of-Way
      Segment lies, or (ii) the American Arbitration Association, or (iii)
      either of them, for the selection of the Appraiser meeting the MAI and
      five (5) year qualifications stated above.

(e)   The three appraisers (the Appraiser and the two appointees) shall each
      make a determination of the fair market value of the rights with respect
      to such Right-of-Occupancy. The determination that is farthest from the
      middle determination shall be disregarded and the remaining two (2)
      determinations shall be averaged in order to establish such value;
      PROVIDED, however, if the low determination and/or the high determination
      are equidistant from the middle determination, all three determinations
      shall be averaged.

(f)   All determinations shall be rendered in writing and signed by the person
      making the report within thirty (30) days from appointment.

(g)   Such determination of the fair market value of the renewal rights with
      respect to such longitudinal Right-of-Occupancy shall be conclusive and
      shall be binding upon Grantee and Grantor without any right of appeal.

(h)   Each party shall pay all fees and expenses charged or incurred by the
      person appointed by such party; however, fees and expenses which cannot be
      reasonably attributed to any one person, and the fees and expenses of the
      Appraiser, shall be borne equally by Grantee and Grantor.

(i)   If the escrow fund is to be used for payment, the fund shall then be
      adjusted to the fair market value reached by the above process and the sum
      paid to Grantor. Any excess funds from the escrow deposit and any interest
      earned on the escrow deposit shall be paid to Grantee.

      This Agreement shall be binding upon and inure to the benefit of the
parties hereto, their respective successors or assigns.

                  to cause the failure, interruption or impairment in the
                  operation of the Qwest System.

            (ii)  "Non-Emergency Unscheduled Maintenance" in response to any
                  potential service-affecting situation to prevent any failure,

            traffic roll or reconfiguration involving cable, fiber, electronic
            equipment, or regeneration or other facilities of the Service
            Recipient, then Service Recipient shall, at Service Provider's
            reasonable request, make such personnel of Service Recipient
            available as may be necessary in order to accomplish such
            maintenance, which personnel shall coordinate and cooperate with

            performance of any Scheduled Maintenance or Unscheduled Maintenance
            so long as this requirement does not interfere with Service
            Provider's ability to perform its obligations under this Agreement.

<PAGE>   29

            Scheduled Maintenance for an additional period of twelve (12) months

            Extended Maintenance Term, as the case may be, the Costs thereof
            shall be allocated among the various interest holders in the
            conduit, Cable and/or fibers affected thereby as follows: (i) Costs
            of Unscheduled Maintenance solely to or affecting a conduit or Cable
            which houses fibers of a single interest holder shall be borne 100%
            by such interest holder; (ii) Costs of Unscheduled Maintenance to or
            affecting a conduit which houses multiple innerduct conduits, not
            including such Costs attributable to the repair or replacement of
            fiber therein, shall be borne proportionately by the interest
            holders in each of the affected innerduct conduits based on the
            ratio that such affected conduit bears to the total number of
            affected innerduct conduits, and (iii) Costs of Unscheduled
            Maintenance attributable to the repair or replacement of fiber,
            including the acquisition, installation, inspection, testing and
            splicing thereof, shall be borne proportionately by the interest
            holders in the affected fiber, based on the ratio that the number of
            affected fibers subject to the interest of each such interest holder
            bears to the total number of affected fibers. All such Costs, which
            are allocated to Service Recipient pursuant to the foregoing
            provisions, shall be the responsibility of and paid by Service
            Recipient within thirty (30) days after its receipt from Service
            Provider of an invoice therefor.

      C)    Costs. "Costs" means the actual, direct costs paid or payable in
            accordance with the established accounting procedures generally used
            by each party, as the case may be, and which its utilizes in billing
            third parties for reimbursable projects, which costs shall include,
            without limitation, the following: (i) labor costs, including wages
            and salaries, benefits and overhead allocable to such labor costs
            (overhead allocation percentage shall not exceed the lesser of (x)
            the percentage Service Provider typically allocates to its internal
            projects or (y) thirty-percent (30%), and (ii) other direct costs
            and out-of-pocket expenses on a pass-through basis (e.g., equipment,
            material, supplies, contract services, etc.).

6.    MAINTENANCE WINDOW (MW)

      Scheduled Maintenance, which is reasonably expected to produce any signal
      discontinuity, must be coordinated between the parties. Generally, this
      work should be scheduled after 11:00 p.m. and before 7:00 a.m. local time.
      Major system work, such as fiber rolls and hot cuts, will be scheduled for
      MW weekends and shall allow work during daylight hours if on a Saturday or
      Sunday. Service Provider and Service Recipient will agree upon a MW
      calendar. The intent is to avoid jeopardy work on high-traffic holidays.
