        b. 41 stub  tower  bases  will  be  supplied  and  installed  on the new
           perimeter  pilings.  26  perimeter  stub  towers will be supplied for
           installation on new perimeter pilings.

        c. Install 132 antennas.

        d. Ground  screens  below  the  existing antennas must be dismantled and
           disposed of.

        e. 14 existing stub  towers and 3 corner towers will be moved from their
           present locations to new pilings to complete the perimeter.

           install  lattice on top of mast,  the lattice is shipped in two parts
           which shall be joined together prior to erecting,  this task includes
           a  100%  check  of  the  torque  of  all  factory   installed   bolts
           (approximately 280 bolts per antenna),  (approximate assembled weight
           1700 lbs.) The base weldments  shall be secured to the pilings with 1
           1/4'-7  high  strength  bolts and nuts,  a torques  wrench to tighten
           these to 500 ft-lbs shall be available.  The supporting  guys must be
           tensioned  to 670 lbs and the tower  must be  brought  to a  vertical
           position  within 2 degrees,  4 each  come-alongs,  dynamometers,  guy
           pulling grips, shackles to attach to base and 2 each transits will be
           required to accomplish  this. A crane capable of attaching to the top
           of the  lattice  and  raising  it to a height  of 75'  shall  also be
           available.

                                     10.b-7
<PAGE>
        h. Install safety climb rail and cable mount angles to structure.

        i. Layout  backbones,  guys and  elements  and  assemble.  File weld .19
           diameter  1100-0  jumper wires to 3/8 thick 6061-T6  aluminum  plate.
           There are 136 jumper wires per antenna and each jumper requires 2" of
           weld. All welds must be 100% inspected;  if any are missed it will be
           necessary  to make the  welds up to 55'  above  the  ground.  Welding
           equipment and a certified  aluminum welder will be required.  A total
           of approximately 18,000 welds will be required.

        j. Raise backbones  (approximate weight 500 lbs each) and secure them to
           structure at approximately  50' above ground. In addition to a crane,
           a bucket  truck  capable  of  reaching  the top of the tower  will be
           required to secure the upper guys  approximately 70' above ground and
           interconnect the element guys.

        k. Tension  upper  guys  and  elements.  This  is a  complex  procedure;
           assistance,  training and supervision will be given by APC personnel.
           The  guys  shall  be  tensioned  to  approximately  1600  lbs and the
           backbones precisely positioned. 4 each come-alongs, dynamometers, guy
           pulling grips, shackles to attach to base and 2 each transits will be
           required to accomplish  this. A bucket truck with an operator capable
           of reaching 75' plus 2 ground personnel shall be available. The lower
           guy  tensions  shall be  re-checked  and adjusted as required at this
           time.  Once this team becomes  familiar  with the procedure it can be
           completed  in 2 to 3 hours  per  antenna  so both the  equipment  and
           personnel shall be available to assist in other areas.

        l. Once 132 antennas  have been  installed,  the existing  ground screen
           will be taken down and disposed of. The new ground screen consists of
           208  assemblies  approximately  80'  square.  Each of  these  will be
           secured to its associated  catenaries and adjacent ground screens 15'
           above ground.  This will require 100 connections  per assembly.  Each
           connection will require 4 crimping operations, 2 on a custom designed
           connector with a Nicopress "J" tool and 2 on a Burndy YPC2A8U Crimpit
           Tap with a Burndy tool MD6 utilizing a BG die (or equal).  There will
           be a total of 20,800  connections  (83,000 crimps) needed to complete
           the groundscreen. Prior to crimping, the crimp area of the wire shall
           be cleaned with a clean shop rag  saturated in denatured  alcohol and
           abraded  with  Scotch  Brite  777.  There  will be a total of  20,800
           connections which will require 41,600 cleaning  operations and 83,200
           crimps.  All cleaning and crimping  operations will be made 15' above
           ground. During installation and tensioning of ground screen, CEI will
           be responsible  for supplying all pulling grips,  ropes,  and pullers
           required.

4. Copper Braid Straps

The 48 existing DP antenna towers were earthed to their  thermopiles  via copper
braids  clamped  at  either  end by  bolt-on  vice  clamps.  This  solution  was
implemented  as a  field  retrofit  to the  need  to  earth  the  towers  to the
thermopiles.  The new thermopiles were  manufactured  with bolt holes to allow a
simple earth strap to be employed.  The 158 earth straps to be manufactured  are
simple lengths of 3/8 inch copper braid, approximately 10 inches long, with lugs
attached at either end. APC will provide the 158 copper braid traps.
