renew by written notice as aforesaid,  Lessor shall be entitled to advertise and
show the Leased Premises during the final three hundred sixty-five (365) days of

      b.    TRIPLE NET INTENT. It is the purpose and intent of Lessor and Lessee
            that  the  base  rent  provided  in  the  above  schedule  shall  be
            absolutely  net to Lessor,  and that Lessee shall pay, AS ADDITIONAL
            RENT, without notice or demand, and without abatement,  deduction or
            setoff and save  Lessor  harmless  from and  against,  all  prorated
            operating  expenses in the manner and as defined in Article 2.02 and
            2.03 of the Standard Office Lease. If Lessee is required to make any
            payment or incur any  expense as provided in this Lease and fails to
            do so, then Lessor, at its option, may

                                       5
<PAGE>


            make the payment or incur the expense on  Lessee's  behalf,  and the
            cost thereof shall be charged to Lessee as additional rent and shall
            be due and payable by Lessee in accordance  with Article 2.02 of the
            Standard Office Lease.


      6.    ASSIGNABILITY OF LEASE BY LESSEE.  Lessee shall not assign, in whole
or in part, this Lease  consisting of the Standard  Office Lease,  all Addendums
and  Amendments  thereto,  or allow it to be assigned,  in whole or in part,  by
operation of law or otherwise  (other than a transfer or a majority  interest of
stock,  merger or  dissolution,  which  transfer of majority  interest of stock,
merger or  dissolution  shall not be deemed an Assignment) or mortgage or pledge
the same, or sublet the Leased Premises,  in whole or in part, without the prior
written consent of Lessor,  which consent shall not be unreasonably  withheld or
delayed,  and in no event shall any such  Assignment  or Sublease  ever  release
Lessee or any Guarantor from any obligation or liability hereunder.

      Notwithstanding  the foregoing,  Lessee shall have the unrestricted right,
at any time during the term or the renewal term, without Lessor's  approval,  to
assign  the Lease or to  sublease  all or any  portion  of the  Premises  to any
parent,  subsidiary  or affiliated  company of Lessee,  or to assign or sublet a
portion  of the space to a customer  when such  subletting  or license  shall be
solely  for  the  purpose  of  permitting  the   installation  or  operation  of
telecommunications  equipment. In no event shall any assignment or sublease ever
release Lessee or any Guarantor from any obligation or liability hereunder.

      Should Lessee enter into an agreement for the sale of substantially all of
its assets in a purchase and sale transaction deemed an asset sale rather than a
stock sale,  Lessee shall obtain the prior  written  consent of Lessor to assign
the Lease to the  entity  purchasing  the  assets,  which  consent  shall not be
unreasonably withheld or delayed and which assignment shall require the approval
of Lessor's  mortgagee  pursuant to the terms of  existing  security  documents.
Should Lessee  request a release of its liability upon approval of assignment of
the Lease to a  purchasing  entity,  Lessor  shall not be  obligated  to release
Lessee from liability  should Lessor or its mortgagee  reasonably deem itself to
be insecure based on the purchasing entity's financial qualifications.


      7.    LEASE  IMPROVEMENTS.  Lessee accepts the "Leased  Premises" in As-Is
condition and Lessee shall be solely  responsible  to build-out  any  unfinished
portions of the Leased  Premises which  currently  exit; all in accordance  with
plans and specifications to be agreed upon by

                                       6
<PAGE>


the parties in the manner as set forth in Article  6.01 of the  Standard  Office
Lease.  Lessee  shall select and contract  with the general  contractor  for any
tenant  improvements  subject to Lessor's  right to reject the  contractor  upon
reasonable  grounds.  A standard AIA  stipulated  sum contract shall be used and
which  shall be agreed  upon by Lessor and  Lessee.  David  Weesner of Weesner &
Associates  shall act as "Landlord's  Architect" who shall approve the plans and
specifications,  work order changes,  and otherwise  protect Lessor's  financial
interests.  All costs, not to exceed $2,000.00 associated with architect,  David
Weesner's  compliance  duties shall be paid by Lessee.  Lessee shall timely make
all payments to the  contractor or  contractors as required in the AIA contract.
Prior to commencing any  improvements,  Lessee shall provide Lessor with a Sworn
Construction Statement and with contractor's  Certificates of Insurance.  Lessee
shall hold Lessor harmless and indemnify  Lessor from any obligation to Lessee's
contractors.

      Lessee  understands  that  currently  unfinished  portions  of the  Leased
Premises are subject to use and occupancy  limits imposed under City of Colorado
Springs and Building Code Requirements.  The following provisions shall apply to
future improvements thereof, to-wit:

      (1)   Should  Lessee  elect,  at its sole option,  to finish the Give-Back
            Space  identified  on Exhibit  A-2 in the Lower  Level of the Leased
            Premises,  Lessee  shall  be  obligated,  at its  sole  expense,  to
            construct the hallway leading from the center stairway of said Lower
            Level to the Building Telephone  Equipment Room; which hallway shall
            be  constructed  as depicted  in the partial  Lower Level Floor Plan
            attached as Exhibit A-2(1). Upon completion thereof, the hallway and
            Telephone Equipment Room shall become a Building Common Area and the
            area  thereof;  or 692  USF/727 RSF shall be deleted  from  Lessee's
            Leased Premises and the Base Rent and Operating Expense  obligations
            of Lessee shall be reduced accordingly.

      (2)   Should Lessee elect to exercise its Give-Back Option as hereinbefore
            provided,  Lessee  shall  be  obligated,  at its  sole  expense,  to
            construct the hallway leading from the center stairway of said Lower
            Level to the Building  Telephone Equipment Room as  referenced above
            and to also  complete  the  hallway  leading  from  said room to the
            center hallway of the Lower Level of the Building all as depicted on
            Exhibit A-2.  Upon  completion,  the entire  hallway,  including the
            hallway to the Telephone  Equipment Room and the Telephone Equipment
            Room shall become a Building Common Area and the entire area thereof
            or  2,413  USF/2,534  RSF  shall be  deleted  from  Lessee's  Leased
            Premises and the Base Rent and Common  Expense  obligation of Lessee
            shall be reduced accordingly.

      (3)   Lessee  understands  that the  Northerly  demising wall dividing its
            Lower Level Leased Premises and the currently vacant Leased Premises
            located  Northerly  thereof is not  completed.  Lessee  agrees  that
            Lessor shall have no  obligation  during the Extended  Lease Term to
            cause  its  completion  provided  that  Lessor,  may,  in  its  sole
            discretion

                                       7
<PAGE>


            and at any time during the  Extended  Lease Term,  elect to complete
            the  construction  thereof.   Within  thirty  (30)  days  after  its
            completion  and  receipt  of  Lessor's  documentation  of its costs,
            Lessee shall  reimburse  Lessor for  one-half  (1/2) of the costs of
            completion  (with  completion  costs  being  deemed  to  consist  of
            sheetrock and tape but unfinished  walls).  Should Lessee elect,  at
            its sole option,  to cause the completion of the unfinished  portion
            of said demising wall,  Lessor shall  reimburse  Lessee for one-half
            (1/2) of the costs  computed in the same manner  within  thirty (30)
            days after receiving verification of the costs thereof from Lessee.

For  purposes of the  completion  of the  above-referenced  hallway  improvement
obligations, Lessee's obligation shall be to complete construction in accordance
with the International Building Code, 2003 Edition, and any more stringent Pikes
Peak  Regional  Building  Code  Requirements  except that  Lessee  shall also be
obligated to install a floorcovering  consisting of vinyl  composition tile that
matches  existing  Building  Common  Area  hallways  as  closely  as  reasonably
practical.


      8.    ELEVATOR.  Lessee shall have the unconditional  right to utilize the
building elevator (a Building Common Area) for transporting  items to include IT
equipment.
