         one party to the other with respect to such orders shall remain in full
         force and effect  until  fully paid or  discharged.  In addition to the

11. Licensed Software

              All copies of the  Licensed  Software  residing  in the  Equipment
         purchased by the Buyer under this  Agreement  shall remain the property
         of S-A and Buyer shall be required to execute the Software License, the
         terms and conditions of which are incorporated  herein by reference and
         made a part hereof. In the event, however, that terms of this Agreement
         conflict  with  terms  of the  Software  License,  the  terms  of  this
         Agreement shall prevail over the Software License.

                a. S-A  grants  to Buyer  during  the Term of this  Agreement  a
                royalty-free,  non-exclusive  license to use the  Trademarks  in
                connection  with  the  promotion  and sale of the  Equipment  as
                provided  for  herein.  Buyer shall not use or  incorporate  the
                Trademarks  on any  other  products  or in or as part of a trade
                name,  corporate name, or business name. Buyer acknowledges that
                considerable  time and money  has been  expended  to create  the
                goodwill associated with the Trademarks.  Buyer shall always act
                in a  manner  that  would  maintain  the  quality  and  goodwill
                associated with the Trademarks.  Nothing  contained herein shall
                give Buyer any interest or right in the Trademarks, except as is
                expressly granted herein.

                b. Buyer further agrees that it will not in any manner represent
                that it has  ownership  of the  Trademarks  and that it will not
                register or attempt to register any Trademarks under the laws of
                any  jurisdiction,  and will not at any time do,  or cause to be
                done,  any act or thing  contesting,  or in any way impairing or
                tending to impair, any part of S-A's right,  title, and interest
                in the  Trademarks,  whether or not they are  registered  in the
                jurisdictions  in  which  Buyer  is  located  or does  business;
                provided,  however,  that Buyer may  register  Trademarks  where
                expressly   required   by  law,   solely  for  the   purpose  of
                establishing its  distributorship  status.  Buyer shall promptly
                notify  S-A of any  unauthorized  use or  infringement  of S-A's
                Trademarks, licenses or rights thereto.

                c. Buyer agrees not to obscure, alter, modify or remove from the
                Equipment any of the Trademarks or other product identification.

12. No Rights in Trademarks

              S-A  grants  to  Buyer  during  the  Term  of  this   Agreement  a
         royalty-free, non-exclusive license to use the Trademarks in connection
         with the  promotion  and sale of the  Equipment as provided for herein.
         Buyer shall not use or incorporate the Trademarks on any other products
         or in or as part of a trade name,  corporate  name,  or business  name.
         Buyer  acknowledges  that considerable time and money has been expended
         to create  the  goodwill  associated  with the  Trademarks.  Buyer will
         always act in a manna that would  maintain  the  quality  and  goodwill
         associated with the  Trademarks.  Nothing  contained  herein shall give
         Buyer any interest or right in the  Trademarks,  except as is expressly
         granted herein.

              Buyer further agrees that it will not in any manner represent that
         it has  ownership  of the  Trademarks  and that it will not register or
         attempt to register any Trademarks under the laws of any  jurisdiction,
         and  will not at any  time  do,  or cause to be done,  any act or thing
         contesting,  or in any way impairing or tending to impair,  any part of
         S-A's right, title, and interest in the Trademarks, whether or not they
         are registered in the  jurisdictions  in which Buyer is located or does
         business;  provided,  however, that Buyer may register Trademarks where
         expressly  required by law, solely for the purpose of establishing  its
         distributorship   status.  Buyer  shall  promptly  notify  S-A  of  any
         unauthorized  use or  infringement  of S-A's  Trademarks,  licenses  or
         rights thereto.

              Buyer  agrees not to  obscure,  alter,  modify or remove  from the
         Equipment any of the Trademarks or other product identification..

13. Other Intellectual Property

         .1 The Buyer  acknowledges  that as an integral part of S-A's business,
         S-A has developed,  at a  considerable  investment of time and expense,
         Trade Secrets and Proprietary  Information,  and acknowledges  that S-A
         has a legitimate  business interest in protecting the Trade Secrets and
         Proprietary  Information.  Buyer acknowledges that it and its employees
         will be entrusted with such Trade Secrets and Proprietary  Information.
         Pursuant  therewith,  the  Buyer  agrees  to  that  it  will  treat  as
         confidential  and will not,  without the prior written approval of S-A,
         use (other than in the performance of its duties  hereunder),  publish,
         disclose,  copyright or authorize anyone else to use, publish, disclose
         or copyright, (a) any information that constitutes Trade Secrets either
         during the term hereof or subsequent  thereto;  or (b) any  information
         that constitutes  Proprietary Information either during the term hereof
         or for two (2) years after  expiration or termination,  with or without
         cause.

         .2 All  records,  notes,  files,  drawings,  documents,  plans and like
         items, and all copies thereof,  relating to or containing or disclosing
         Trade Secrets or Proprietary  Information of S-A which are made or kept
         by the Buyer or which are  disclosed to or come into the  possession of
         the Buyer,  shall be and remain the sole and exclusive  property of S-A
         and shall be returned to S-A upon  expiration  or  termination  of this
         Agreement.

         .3  The  Buyer  further  agrees  that  it  will  require  each  of  its
         shareholders,  officers,  directors and employees who act on its behalf
         with respect to this Agreement to be bound by the  requirements of this
         Agreement  and  that,  upon  request  of S-A,  the Buyer  will  provide
         evidence of such requirement to S-A.

14. Injunction

              The Buyer agrees that its (or anyone acting on its behalf)  actual
         or threatened  breach of the  provisions of Sections 10, 11 or 12 shall
         constitute  irreparable  harm to S-A, and S-A, in addition to all other
         rights,  shall be entitled to seek an injunction  restraining the Buyer
         or  such  person  therefrom.  Nothing  herein  shall  be  construed  as
         prohibiting  S-A from  pursuing  any other  available  remedy  for such
         breach or threatened breach, including the recovery of damages from the
         Buyer or such  person.  This  provision  shall remain in full force and
         effect  in the event the Buyer or such  person  should  claim  that S A
         violated any of the terms of this Agreement.  In such event,  the Buyer
         or such person agrees to pursue such claim against S-A independently of
         the covenants set forth in this section.

15. Proprietary Rights Indemnification

         .1  Indemnification.  S-A shall settle, at its sole cost, or defend and
         pay costs and damages  finally awarded in any suit against the Buyer to
         the extent based upon a finding that the design, construction or use of
         the Equipment,  including  Licensed  Software (either  separately or in
         combination),  furnished under this Agreement, as furnished and used in
         accordance  with  S-A  instructions,  infringes  a  patent,  trademark,
         copyright or other intellectual property right of a third party (except
         infringement  which is  directly  caused by  incorporating  a  specific
         design or modification at the Buyer's request). S-A shall not indemnify
         the  Buyer's  for that  portion  of any  final  award  that is based on
         revenue  derived from use of the Equipment and that is in excess of the
         maximum liability of S-A provided in Section 15.5 below.

         .2 Procedures.  In the event of any allegation of  infringement  of the
         type  described in Section  15.1 or a claim or suit based  thereon (the
         "Allegation"),  the Buyer shall promptly  notify S-A of such Allegation
         in writing.  S-A shall promptly commence efforts to settle or to defend
         against such Allegation and the Buyer shall  reasonably  cooperate with
         S-A at the expense of S-A in such settlement or defense.

         .3  Injunction.  In the event that the use of the  Equipment  delivered
         under this  Agreement  is  enjoined  or, in the  discretion  of S-A, is
         likely to be enjoined,  S-A shall do one or more of the  following,  at
         S-A's option:

              (a) obtain for the Buyer the right to use the  infringing  item at
              no cost to the Buyer;

              (b) modify the  infringing  item so that it becomes  noninfringing
              while  remaining  in  compliance  with the  Specifications  in all
              material respects;

              (c)  replace  the  item  with a  noninfringing  item  which  is in
              compliance with the Specifications in all material respects; or

              (d) if (a), (b) or (c) cannot be effected by S-A's  reasonable and
              diligent  efforts,  and  further  subject  to the Notice of Refund
              Option,  below,  refund  the  amount  paid  by the  Buyer  for the
              applicable   Equipment,   less   depreciation   calculated   on  a
              straight-line basis over a five (5) year period, provided that the
              payment of any such  refund  shall not become due until  return by
              the Buyer of the applicable Equipment.

              (e)  Notice of  Refund  Option.  In the  event S-A shall  elect to
              exercise the provisions of subsection  15.3(d),  above,  S-A shall
              give Buyer 90 days written  notice of such  election.  Buyer shall
              have the option,  during such 90 day period,  to  negotiate on its
              own behalf a license or other agreement with the Plaintiff so that
              such  item  is  no  longer  infringing.  In  the  event  Buyer  is
              successful,  S-A shall under Section 15.1 above,  pay on behalf of
              Buyer any royalties  and other costs  related to such  settlement,
              including  attorney's  fees, up to the amount set forth in Section
              15.5, below.

         .4 Combinations and Modifications.  Notwithstanding any other provision
         of this  section,  S-A shall  have no  liability  for any  infringement
         arising  from (i) use of  delivered  items in  combination  with  other
         items, unless S-A sold, made or specifically  recommended them all as a
         combination, or the specific combination would be necessary for the use
         in the normal  course of events in connection  with the Equipment  sold
         hereunder,  or (ii)  modification of items after  delivery,  unless S-A
         made or specifically recommended the modification,  or the modification
         constitutes  normal  repair,   replacement  or  implementation  of  S-A
         provided options and enhancements for the Equipment sold hereunder.

         .5 Limitation. Notwithstanding any other provision of this Agreement to
         the  contrary,  this Section 15 states the entire  liability of S-A and
         the sole and exclusive remedy of the Buyer for any alleged infringement
         of a third party's intellectual  property right arising out of the sale
         or use of the  Equipment  supplied  under this  Agreement  or a process
         practiced by such item,  and S-A shall not be liable under this Section
         15 in the  aggregate  for any amount  exceeding  the total price of the
         Equipment purchased hereunder.

16. Indemnification and Limitation of Liability

         .1 The  Buyer  agrees  to  indemnify  and  hold  S-A and its  officers,
         directors and employees harmless from any loss,  damage,  liability and
         expense on account of bodily  injuries or  physical  damage to tangible
         property,  including the property of S-A,  arising from any  occurrence
         caused by a  negligent  or willful  act or omission of the Buyer or any
         employee or agent of the Buyer (other than S-A),  or of an  independent
         contractor of the Buyer (other than S-A), which indemnity shall survive
         this Agreement.

         .2 S-A  agrees  to  indemnify  and hold  the  Buyer  and its  officers,
         directors and employees harmless from any loss,  damage,  liability and
         expense on account of bodily  injuries or  physical  damage to tangible
         property,  including  the  property  of the  Buyer,  arising  from  any
         occurrence  caused by a negligent or willful act or omission of S-A, or
         any  employee or agent of S-A or of any  subcontractor  or  independent
         contractor of S-A, which indemnity shall survive this Agreement.

         .3  UNDER NO  CIRCUMSTANCES  SHALL  S-A BE  RESPONSIBLE  FOR  INDIRECT,
         SPECIAL,  INCIDENTAL,  CONSEQUENTIAL,  PUNITIVE,  OR EXEMPLARY  DAMAGES
         ARISING  OUT OF OR IN  CONNECTION  WITH  THIS  AGREEMENT  OR ANY  OTHER
         RELATED  AGREEMENTS  OR ANY ACTS OR OMISSIONS  ASSOCIATED  THEREWITH OR
         RELATING  TO THE USE OF ANY  EQUIPMENT,  LICENSED  SOFTWARE OR SERVICES
         FURNISHED, WHETHER SUCH CLAIM IS BASED ON BREACH OF WARRANTY, CONTRACT,
         TORT OR OTHER LEGAL THEORY AND REGARDLESS OF THE CAUSES OF SUCH LOSS OR
         DAMAGES OR WHETHER ANY OTHER REMEDY  PROVIDED  HEREIN FAILS,  NOR SHALL
         S-A'S  TOTAL  LIABILITY  EXCEED AN AMOUNT  EQUAL TO THE TOTAL  PURCHASE
         PRICE PAID BY THE BUYER TO S-A UNDER THIS AGREEMENT, MEASURED AS OF THE
         DATE SUCH LIABILITY OF S-A SHALL FIRST EXIST.

17. Force Majeure

              S-A shall  not be  responsible  for  delays  caused by  conditions
         beyond the reasonable control of S-A, including without limitation such
         conditions as acts of God, civil insurrections,  wars, sabotage, fires,
         floods, sun outages,  atmospherics and externally caused  interference,

         different  conditions  beyond the reasonable  control of S-A including,
         without  limitation,  limitations  and  restrictions  imposed  by third
         parties.  In  the  event  of  delay  due  to any  such  condition,  any

         purchase  orders  to the  Buyer  which  contains  a  penalty  clause or

24. Arbitration

         .1  Except  as  otherwise   provided  in  the  Software  License,   any
         controversy  or claim  between or among the parties,  including but not
         limited to those  arising out of or relating to this  Agreement  or any
         agreements or  instruments  relating  hereto or delivered in connection
         herewith and any claim based on or arising from an alleged tort,  shall
         if  incapable  of  resolution  by mutual  agreement  in good faith,  be
         determined by arbitration as provided in this Section 24.

         .2 The  arbitration  shall be conducted in  accordance  with the United
         States  Arbitration  Act  (Title 9, U. S.  Code),  notwithstanding  any
         choice of law  provision in this  Agreement,  and under the  Commercial
         Arbitration Rules of the American Arbitration  Association ("AAA"). The
         arbitration shall be conducted in the City of Seattle, Washington . The
         arbitrator  shall give effect to statutes of limitation in  determining
         any claim.  Any controversy  concerning  whether an issue is arbitrable
         shall be determined by the  arbitrator.  The decision of the arbitrator
         shall  be  final  and  binding  on  the  parties.   Judgment  upon  the
         arbitration award may be entered in any court having  jurisdiction.  In
         rendering any decision or making findings of fact the arbitrator  shall
         apply the express intentions of the parties set forth in this Agreement
         and the laws of the State of Georgia,  including without limitation any
         applicable  statutes,  regulations and binding judicial  decisions,  as
         such would be  applied  by the  courts of the State of Georgia  and the
         United States District Court for the Northern District of Georgia.

         .3 In connection with any  arbitration  having an amount in controversy
         of less than  $1,000,000,  such  arbitration  shall be  conducted  by a
         single  arbitrator,  chosen by the AAA.  The AAA shall be guided by any
         applicable  rules with  respect to the  choosing of an  arbitrator  for
         arbitrations  conducted pursuant to the Commercial Arbitration Rules of
         the AAA,  and,  in  addition,  thereto,  (i) the AAA shall  attempt  to
         appoint an arbitrator having a technical  background,  where available,
         consistent  with the  technical  issues  and  procedures  which are the
         subject  matter  of this  Agreement  and (ii) the AAA  shall  prefer an
         arbitrator who is an attorney in good standing and licensed to practice
         law within the State of Georgia.  In  connection  with any  arbitration
         where the amount in controversy is equal to or greater than $1,000,000,
         the  arbitration  shall be  conducted  of a panel of three  (3) or more
         arbitrators  chosen  by the AAA,  giving  preference  to those  factors
         identified in subsections (i) and (ii) in the foregoing sentence.

         4 Notwithstanding any of the foregoing provisions, nothing contained in
         this Section 24 shall  prohibit  either  party from seeking  injunctive
         relief in any court having jurisdiction thereof and each party consents
         to such jurisdiction.

IN WITNESS  WHEREOF,  the parties  hereto have caused this  Agreement to be duly
executed and delivered by their respective authorized  representatives as of the
date first above written.

                            S-A DAMA Features for FGB
                                and 800 950 1077
                              Dec. 12, 1995, Rev. 4

FGB (Feature Group B)

     FGB is a trunk class offered by a Local Exchange  Carrier (LEC) to an Inter
Exchange  Carrier  (IXC)  before the  advent of FGD equal  access  trunking  was
available.  In such a non equal access LEC office FGC signaling  also exists but
historically  is only  grandfathered  to AT&T as they were the original and only
IXC. (There have been exceptions in Alaska where GCI has received FGC from a LEC
for payphone access and 800 number  lookup).  FGB can coexist with FGD when that
service is available. There are two types of FGB signaling; one with ANI and one
without. FGB with ANI is a NECA offering without any additional charges over and
above FGB without ANI. The following  will be a description  of how it functions
and what S-A will have to incorporate  into the DAMA product to provide this FGB
requirement for GCI.  Drawings are also included showing the signaling  protocol
exchanges for both types.

     S-A shall  design  the DAMA  product  for the  following  two FGB  trunking
signaling  protocol.  GCI's FGB Carrier  Identification  Code (CIC) is 1077. FGB
access NXX is 950 so the access number is 950 1077.  There will be a new file to
be downloaded to the CUs called the "Parameter  File". The CIC will be placed in
the new downloadable  file.  Format of the new file is TBD. FGB with ANI and FGB
without ANI will be selectable from the same field in the parameter screen where
FGC, FGD, IMT, and PBX are  currently  selected.  The new entries will be FGBANI
and  FGBNOANI.  FGB with ANI and FGB without ANI and IMT  protocols  will reside
within the same state machine FGB###.BIN The first described is FGB with ANI.

       FGB with ANI

       Customer phone number is 907 265 5650
       Customer dials GCI FGB Access number 950 1077
       Customer wants to call 1+213+554+1212

       Customer then enters the called number as 1+213+554+1212  from their DTMF
       phone. (No MF tones or rotary phones)

     The  customer  with local LEC line will dial 950 1077.  The LEC, at the LEC
GCI FGB trunk,  will then send an off hook seizure to the DAMA channel unit. The
DAMA channel unit will then send an approximate  200 ms off hook wink to the LEC
when the DAMA is ready to receive  digits in MF. The LEC will spill  KP9501077ST
important  digression  -- In most all cases the LEC when asked will suppress all
digits of the called number and just spill KP ST. This shortens post dial delay.
The DAMA must be able to just  recognize  KP ST for this trunk  type).  The DAMA
then  returns an off hook  seizure to the LEC.  The LEC  recognizes  this as the
request  for ANI and then  sends the ANI as KP 0 2655650  ST.  This ends the LEC
trunking  signalling   protocol,   (with  the  exception  of  ultimate  on  hook
disconnect). The DAMA then shall return a single frequency 400 Hz dial tone. (If
it hasn't been  observed  already this  signalling  protocol is identical to FGC
originating  previously  designed for DAMA). The similarity ends however at this
point where the DAMA returns  dial tone.  The  originator  of the call who first
dialed 950 1077 to access GCI DAMA (who will continue the signalling addressing)
must now at the DAMA dial tone enter the 1+10 digit called number. This 10 digit
destination number must replace the previous called number 9501077,  if spilled,
with  the new 10  digit  called  number  for the  purpose  of call  routing  and
completion.  The ANI will be used for  billing.  The DAMA channel unit must have
the filed 907 NPA for purpose of  completing  the ANI with the  prefacing of the
907 to the seven digit ANI spill.  Presently the DAMA NMS has ANI  validation to
the extent that if an ANI is to be turned off for non payment it is entered into
the system to be blocked.  If an ANI is to route normal it is not  entered.  S-A
shall provide the  capability to reverse this based on a CU basis so that an ANI
must be  entered to be allowed to route and that if no ANI is present in the NMS
database then it will block the call and go to recording.

     Next will be described the second scenario of FGB without ANI.

       Customer then enters a 6 digit  authorization  code and the called number
       as 123456  +1+213+554+1212  from their DTMF phone. (No MF tones or rotary
       phones)

     The  customer  with local LEC line will dial 950 1077.  The LEC, at the LEC
GCI FGB trunk,  will then send an off hook seizure to the DAMA channel unit. The
DAMA channel unit will then send an approximate  200 ms off hook wink to the LEC

dial tone. This ends the LEC trunking signalling  protocol,  (with the exception
of  ultimate  on hook  disconnect).  The  user,  in  continuing  the  addressing
signalling, must enter at the tone a 6 digit authorization code and then the 1 +
10 digit  called  number  from their DTMF  phone.  The  authorization  code will
replace the ANI for billing  purposes  only but will not replace the ANI for any
other  purpose such as FGD repeat.  Where FGB does not provide an actual ANI the
NS will use the telephone number entered in the routing table of the originating
CU as the ANI for FGC and FGD  repeat.  This  scheme is the same as what FGC and
FGD do for an IMT originating  call which has no ANI. If no telephone  number is
used an ANI of KP+ST will be output by the FGC or FGD repeat  terminating trunk.
This 6 digit  authcode  (Called the Hometown  authcode  feature by GCI Mktg when
going to non equal access areas) must be validated in the NMS in a database of 6
digit authcodes  stored.  S-A shall provide memory for up to 20 thousand 6 digit
authorization codes.

Bellcore standards documents are available for FGB signalling and function.

800 950 1077

     This feature can be best  described  as 800 950 1077 "peel out".  S-A shall
provide  the  following  set of  feature  requirements.  In the  case  where  an
originating  DAMA FGC or FGD channel unit  receives the GCI 800 950 1077 number,
regardless  of whether the channel  unit trunk group is an 800 query or route as
is one,  the DAMA NMS or channel  unit will  recognize  this number and "peel it
out"  and  keep it  temporarily  within  the  originating  channel  unit for the
following  additional  call  processing.  All LEC  trunking  signalling  to DAMA
channel  unit has  already  taken  place once the 800 950 1077 and ANI have been
received.  Once the 800 950 1077 number is  received  and  recognized  S-A shall
design the DAMA product so that the channel unit will return a single  frequency
400Hz.  dial  tone.  Then the user,  from a DTMF  phone,  will dial a 0+10 digit
destination  number. Then the DAMA channel unit will return a "Bong tone" to the
user followed by a recording that says "Enter your GCI calling card number now".
Then the customer,  from their DTMF phone,  will enter a 14 digit GCI Big Dipper
calling  card  number.  The 14 digit GCI Big Dipper  calling  card  number  will
replace the ANI sent to the NS for billing  purposes.  Then the return link will
send all this information to the NMS. The NMS will validate the 14 digit number.
If validated  then the call will route and  terminate to a  destination  channel
unit based on the 0+10 digit called number.  At the same time a recording to the
originator  will say "Thank you for using GCI".  S-A shall provide memory for up
to  100,000 14 digit  calling  card  numbers.  In the event  where the  customer
originated the call from a rotary phone S-A shall provide for the following.  At
the point where the DAMA channel unit has returned the single  frequency 400 Hz.
dial tone and the  customer  cannot  enter the DTMF 0+10 number as they are at a
rotary phone there needs to be incorporated a default timer value where the call
can be routed to the operator  trunking should no DTMF digits be received before
the  expiration  of the timer.  This timer needs to be  programmable  within the
range of 1 second to 15  seconds.  If no DTMF  digits  are  received  within the
programmed default range then the call will be routed as a 0- FGD repeat call to
the terminating  channel unit designated for 0- operator calls.  That is the FGD
repeat trunk group will repeat the  originating  ANI and insert 0- as the called
number. This will allow an operator to handle the call verbally.
