<PAGE>
                  "Operating  Cash  Flow"  means,   for  the  Borrower  and  the
         Restricted Subsidiaries,  for any period, determined in accordance with
         GAAP,  the  consolidated  net income  (loss) for such period taken as a
         single accounting  period,  excluding  extraordinary  gains and losses,
         plus the sum of the  following  amounts  for such  period to the extent
         included in the  determination  of such  consolidated  net income:  (a)
         depreciation  expense,  (b)  amortization  expense  and other  non-cash
         charges  reducing  income,  (c) Net Total  Interest  Expense,  (d) cash
         income tax expense for the Borrower and  Restricted  Subsidiaries,  (e)
         deferred  income Taxes for the Borrower  and  Restricted  Subsidiaries,
         plus (f) for the fiscal  quarter in which the  Borrower  purchases  the
         transponders  pursuant to that certain  Transponder  Purchase Agreement
         for Galaxy X, dated August 24, 1995, among GCI Communication  Corp. and
         Hughes  Communications  Galaxy,  Inc., now held by PanAmSat  Corp.,  as
         assignee, and that certain Transponder Service Agreement,  dated August
         24, 1995, among General  Communication Corp. and Hughes  Communications
         Satellite  Services,  Inc. (the "Galaxy X  Transponders"),  now held by
         PanAmSat Corp., as assignee,  the annualized amount of economic savings
         of the Borrower  resulting from the Borrower's  direct purchase of such
         Galaxy X  Transponders  instead of leasing  such Galaxy X  Transponders
         from GCI  Satellite  Co.,  Inc.  and  leasing  transponders  from other
         providers;  provided,  the  calculation  is made after giving effect to
         acquisitions  and  dispositions  of  assets  of  the  Borrower  or  any
         Restricted  Subsidiary  during such period as if such  transactions had
         occurred on the first day of such period. In calculating Operating Cash
         Flow for determination of compliance with financial covenants beginning
         with the  fiscal  quarter  ending  March 31,  1999,  losses  from local
         telephone   businesses   shall  be  offset  by  amounts  not  exceeding
         $20,000,000  contributed  to the Borrower  from the net proceeds of any
         offering of preferred  stock issued by GCI. The amount  attributable to
         such net proceeds  which is available  for such offset shall be reduced
         by the  amount  of net  proceeds  actually  used  for  such  offset  in
         determining  compliance  with  financial  covenants as permitted in the
         immediately preceding sentence.
