          at Titan's expense. The Successful Testing of the Key Equipment shall
          be deemed to have occurred upon delivery of conditional certification
          by Titan and a PSN authorized representative to Tedco of such
          Successful Testing (the "Certification"). Within sixty (60) days Titan
          shall successfully prove the Pseudo-Mesh capabilities of the RTS by
          operating with multiple hubs, at which time the conditional
          Certification automatically becomes effective. Delivery of the Initial
          Order shall commence within two months after the conditional
          Certification.

     4.4  CURE PERIOD.

          Equipment has failed to meet the Final Acceptance Test Criteria, Tedco
          and PSN will jointly notify Titan of such Failure in writing and Titan
          will be granted sixty (60) days to correct the Key Equipment (the
          "Cure Period"). Following the Cure Period, the Key Equipment shall 
          again be required to meet the Final Acceptance Test Criteria attached
          hereto as Schedule 4.3(b). The Key Equipment shall be deemed to have
          had a Successful Testing pursuant to the After Cure Test upon delivery
          of the Certification by Titan and a PSN authorized representative to
          Tedco of such Successful Testing.

     4.5  TESTING DISPUTES.

          If, at any time, any of the parties hereto disagree as to any issue
          pursuant to this Agreement including, without limitation, whether a
          Successful Testing has occurred, such disagreement shall be resolved
          by such parties in accordance with the provisions of Section 23
          hereof.

     4.6  FAILURE OF FINAL ACCEPTANCE TEST.

          If, following the After Cure Test, both Titan and a PSN authorized
          representative agree that the Key Equipment has failed to meet the
          Final Acceptance Test Criteria, such failure shall be considered a
          Breach of this Agreement (as defined herein), and thereafter Tedco and
          PSN may, in their collective discretion, pursuant to the terms and
          subject to the conditions of Section 16, jointly terminate this
          Agreement.

16.  BREACH

     16.1 DEFINITION.

          Subject to the terms and conditions of Section 15, if either PSN or 
          Tedco, on the one hand, or Titan, on the other hand, fails to 
          perform any material obligation under this Agreement, and such 
          failure shall continue unremedied for thirty (30) days following 
          written notice of such failure (a) from Titan, if such failure is 
          by PSN or Tedco and (b) jointly by Tedco and PSN if such failure is 
          by Titan, such failure shall, after expiration of said thirty (30) 
          days constitute a "Breach(ing)" of this Agreement.

     16.2 CONSEQUENCES.

          In the event of a Breach of this Agreement, the non-Breaching party 
          may, at its option, terminate this Agreement without any further 
          obligation or liability hereunder.  The non-Breaching party shall 
          also have the right to pursue any and all rights it may have 
          against the Breaching party now or hereafter under the Law, 
          including without limitation (i) the right to obtain injunctive

          party shall be Tedco and PSN, collectively.

     17.  COMPLIANCE WITH LAWS.

          Tedco and PSN agree that they will not, directly or through an 
          intermediary, give or offer to give anything of value to a 
          government official or representative or a political party official 
          or candidate for political office for purposes of inducing such 
          person to use his influence to assist Tedco, PSN or Titan in 
          obtaining or retaining business or to benefit Tedco, PSN or Titan 
          or any other person in any way, and will not otherwise violate the 
          U.S. Foreign Corrupt Practices Act of 1977.  Any such breach of the 
          foregoing obligation shall constitute a material breach of this 
          Agreement.  Tedco and PSN acknowledge that the products to be 
          provided by Titan pursuant to this Agreement may be subject to 
          approval for export by the United States government, and, 
          accordingly, each of the parties hereto agree that this Agreement 
          is subject to all United States laws and regulations related to 
          export and to all administrative acts of the United States 
          Government pursuant to such laws and regulations.

     18.  FORCE MAJEURE.

          As used in this Agreement, "Force Majeure" means any act of God, 
          governmental action or Law (whether in its sovereign or contractual 
          capacity), or any other circumstances reasonably beyond the control 
          of the party including, but not limited to, weather or acts or 
          omissions of the other party or any other Person (excluding any 
          Affiliates of such party).  If any failure or delay by either party 
          in the performance of any of that party's obligations under this 
          Agreement results from a Force Majeure, that failure or delay shall 
          not constitute a Breach of this Agreement.

21. CONFIDENTIALLY

    21.1 DEFINITIONS.

         As used in this Agreement, the following terms shall have the meaning
         set forth below:

         (a)  "Disclosing Party" shall mean the party which is disclosing
              Proprietary Information:

         (b)  "Receiving Party" shall mean the party to which Proprietary
              Information is disclosed:

         (c)  "Proprietary Information" shall mean information of any nature in
              any form, including without limitation all writings, memoranda,
              copies, reports, papers, surveys, analyses, drawings, letters,
              computer printouts, software, specifications, data, graphs,
              charts, sound recordings and/or pictorial reproductions which
              have been reduced to written form. All Proprietary Information
              shall be marked as proprietary with an appropriate legend,
              marking, stamp or other obvious written identification by the
              Disclosing Party prior to disclosure. In the event either party
              discloses its Proprietary Information to the other party other
              than in the manner provided for above, the Disclosing Party shall
              promptly inform the Receiving Party that such information is
              deemed proprietary, and shall provide the Receiving Party with a
              brief written description of such information within thirty (30)
              days of such disclosure, identifying therein the manner, place,
              and date of such disclosure and the names of the Receiving
              Party's representatives to whom such disclosure was made.

    21.2 OBLIGATIONS CONCERNING PROPRIETARY INFORMATION.

         Upon receiving Proprietary Information, the Receiving Party shall keep
         in strict confidence and not disclose to any Person any of the
         Disclosing Party's Proprietary Information except as otherwise
         provided by the terms and conditions of this Agreement. The Receiving
         Party shall not use such Proprietary Information except for the
         purposes expressly identified herein without the prior written
         approval of the Disclosing Party.

         The Receiving Party shall not be liable for disclosure or use of any
         Proprietary Information if the same:

                                          33



          (a)  is in or enters the public domain, other than by a Breach of this
               Agreement, prior to such disclosure by the Receiving Party;

          (b)  is known to the Receiving Party at the time of first receipt or
               thereafter becomes known to the Receiving Party without similar
               restrictions from a source other than the Disclosing Party whom
               the Receiving Party knows not to be similarly bound; or 

          (c)  is developed by the Receiving Party independently of any
               disclosure thereunder as evidenced by written records.

          The Receiving Party will make Proprietary Information of the
          Disclosing Party available only to those of its employees having a
          "need to know" in order to carry out their functions in connection
          with the purpose stated in the  recitals hereof. The Receiving Party
          shall not mechanically copy or otherwise reproduce Proprietary
          Information except for the purpose of internal evaluation. Each of
          such copies or reproductions shall contain the same proprietary
          marking as the original.

          The disclosure of Proprietary Information hereunder shall not be
          construed as granting either a license under any patent, application,
          or copyright, or any right of ownership in said Proprietary
          Information, nor shall such disclosure constitute any representation,
          warranty, assurance, guarantee or inducement by the Disclosing Party
          with respect to infringement of patents or other rights of others.

          Should the Receiving Party be required to disclose Proprietary
          Information received by order of a governmental agency, legislative
          body or court of competent jurisdiction, the Receiving Party shall
          promptly notify the Disclosing Party thereof, and, upon the request of
          the latter shall fully cooperate with the Disclosing Party in
          contesting such disclosure. If after such contest disclosure is still
          required, then the Receiving Party shall seek confidential treatment
          of such information from such governmental agency, body or court.
          Except in connection with failure to discharge responsibilities set
          forth in the proceeding sentence, neither party shall be liable in
          damages for any disclosures pursuant to such governmental, legislative
          or judicial order.

          All Proprietary Information in tangible forms of expression which has
          been delivered or thereafter created by copy or reproduction pursuant
          to this Agreement shall be and remain the property of the


                                       34


          Disclosing Party. All such Proprietary Information and any and all
          copies and reproductions thereof shall, within thirty (30) days of
          written request by the Disclosing Party, be either promptly returned
          to the Disclosing Party or destroyed at the Disclosing Party's
          direction. In the event of such requested destruction, the Receiving
          Party shall provide to the Disclosing Party written certification of
          compliance therewith within thirty (30) days of such written request.

     21.3 PRESS RELEASE.

          The parties shall use their best reasonable efforts to agree upon a
          mutually acceptable press release with respect to the parties' general
          business relationship under this Agreement and to jointly issue and
          release such press release as soon as reasonably practical.

     21.4 GENERAL.

          The provisions of this Section 21 shall control in lieu of and
          notwithstanding any proprietary or restrictive legends or statements
          inconsistent with this Section 21 which may be associated with any
          particular information hereunder. The provisions of this Section 21
          shall continue to govern the exchange of information for five (5)
          years after this Agreement is terminated.

23. SETTLEMENT OF DISPUTES; ARBITRATION.

    23.1 DISPUTES.

         Any dispute or disagreement arising between any of the parties hereto
         shall be resolved according to the following dispute resolution
         procedure:  First, such dispute shall be addressed to each party's
         project manager for discussion and attempted resolution.  If any such
         dispute cannot be mutually resolved by such project managers within
         five (5) business days, then such dispute shall be immediately
         referred to the President of each party for discussion and attempted
         resolution.  If such dispute cannot be mutually resolved by such
         parties' representatives within fifteen (15) days (or such longer
         period as may be mutually agreed upon), then such dispute or
         disagreement shall be referred to arbitration in London, England, in
         accordance with the International Commercial Arbitration Rules (the
         "Arbitration Rules") of the International Chamber of Commerce ("ICC")
         in effect on the date such notice is given, except that such
         arbitration shall be before one arbitrator.  Once appointed, the
         arbitrator shall appoint a time and place for a prehearing status
         conference not more than fifteen (15) days from the date of his or her
         appointment, and shall appoint a time and place for a final hearing
         not more than forty-five (45) days from the date of the status
         conference.  The final hearing shall conclude no later than thirty
         (30) days after its commencement.  The parties hereto agree and
         acknowledge that in the event of any dispute or disagreement between
         them, each of the parties shall continue to perform their obligations
         pursuant to this Agreement during the pendency of the dispute
         resolution procedures set forth herein; PROVIDED, HOWEVER, that Titan
         shall only be obligated to perform pursuant to this Agreement so long
         as (a) Tedco and PSN continue to make payments hereunder pursuant to
         the provisions of Section 6.1 hereof, or (b) Titan is able to continue
         drawing dawn under the Letters of Credit as described in Section 6.2,
         6.3 and/or 6.4 hereof.  Notwithstanding the above, the parties shall
         have the right to seek injunctive relief in any federal or state court
         of competent jurisdiction in California.

    23.2 ARBITRATOR.

         The party that demands arbitration of the unresolved dispute or
         disagreement shall specify in writing the matter to be submitted to
         arbitration and at the same time choose and nominate a


                                          37



         competent person to act as the arbitrator.  Within seven (7) days
         after such notice, the other party shall indicate in writing its
         concurrence or non-concurrence in the arbitrator nominated by the
         other party.  If the parties to such arbitration fail to concur in the
         proposed arbitrator, then upon application by either party, the
         dispute or disagreement shall be referred for resolution by a single
         arbitrator appointed in accordance with the Arbitration Rules by the
         ICC.

    23.3 AWARD.

         Prior to the final hearing of any arbitration proceeding, each party
         shall present to the arbitrator and the other party a proposed award.
         The arbitrator shall be required to adopt as the final award, and
         without modification, one of the awards proposed by the parties.  The
         arbitrator shall render a written decision stating with reasonable
         detail the reasons for the award adopted.  Any cash component of the
         adopted award shall be payable in United States dollars through a bank
         in the United States.

    23.4 COSTS.

         Each party shall bear its own cost of preparing for and presenting its
         case; and the cost of arbitration, including the fees, and expenses of
         the arbitrator, will be shared equally by the parties to such
         arbitration.

    23.5 ENFORCEMENT.

         The arbitration award shall be final and binding upon the parties and
         may be confirmed by the judgment of any court having appropriate
         jurisdiction including without limitation California.  Each party
         hereto specifically reserves the right to seek specific performance,
         injunctive relief and their equitable remedies in any court having
         appropriate jurisdiction.  To the extent that this Agreement provides a
         party with a right to seek injunctive relief, such party may seek
         injunctive relief in any state or federal court of competent
         jurisdiction to enforce its rights as set forth in this Agreement.

26.  NO AGENTS.

     Except as otherwise expressly provided in this Agreement, no party hereto
     shall act as an agent of any other party hereto, or take any action or do

                                   SCHEDULE 4.2(a)
                             UPGRADES TO RURAL TERMINALS

1.  REDUNDANT NCS.

    Titan will develop a capability to have a second NCS suite of hardware 
operate as a Redundant NCS and take over if the primary NCS fails.  The 
second NCS will utilize an NCS computer, a CC computer and a full set of FOW 
and ROW modems and a hardware switch to switch from the primary to the 
secondary NCS. The secondary NCS will maintain a data base that duplicates 
the primary NCS so that the secondary NCS has full knowledge of all calls 
that are in progress and will be able to take over operation from the primary 
NCS without disconnecting calls in progress.  The system will include one NMS 
computer; since the system can continue operation even if the NMS fails, 
redundancy of that computer is not required.  The various operating 
components, NMS, NCS, CC and modems will exchange keep alive packets to 
assure that all components are working.  If the keep alive packets are not 
received properly, a baton pass will be initiated so that the secondary NCS 
takes over operation and the primary NCS is taken off line.

    This development will provide for redundancy when the secondary NCS is 
co-located with the primary NCS.  It will be easily extendible, with some 
separately funded hardware and software additions, to provide for the case 
when the secondary NCS is at a different geographic location from the primary 
NCS.

    The development effort addressed herein is the development of the 
software to implement the redundancy function.  PSN will need to separately 
procure the Secondary NCS' computers, CCM1500s and redundancy switch needed 
to install the function.

    This facility is planned to be operational in March 1998.

2.  METERING PULSE IMPLEMENTATION.

    Titan will add generation of the metering pulse in the RTT hardware and 
software.  The metering pulse is a [...***...].  The tone is 
only applicable for RTT-originated calls, as it is used for initiating 
billing to a payphone.  The tone is added to the voice channel from the RTT 
towards the telephone attached to the RTT whenever the PSTN phone answers the 
call (this indicates to a payphone, such as the TUT phone, that it should 
start charging the user).

    The implementation requires the following changes:


* Confidential Treatment Requested

                                       1.


         (A)  The RTT hardware starting with serial number 090046002 will
              contain new circuitry to generate the tone.  It will start and
              stop the generation of the tone upon command from the CSP.

         (B)  The CSP software was changed at version 3.17 to create the
              metering pulse upon receipt of the answer indication from Telkom.

3.  TUT REPLACEMENT.

    Titan will implement new code such that the billing information is 
provided over the satellite link, rather than being calculated by the TUT.  
This will allow PSN to use any inexpensive phone at the RTT site.

    The planned architecture is that the NCS will connect to a computer 
provided by PSN that contains the billing tariff algorithms and provides the 
billing calculation.  The final cost of the call will then be transmitted 
over the satellite link and printed on a small printer, provided by PSN, that 
is attached to the data port on the RTT Indoor Unit.

4.  PROJECT PLAN FOR IMPROVED CHANNEL SPACING.

    The original Xpress Connection development contract specified that the 
system would be capable of providing a minimum of [...***...] circuits per 
transponder and channel tuning increments and occupancy would not be greater 
than [...***...] per carrier.  The [...***...] occupancy limit allows for up 
to [...***...] per transponder.  In order to provide the possibility of 
increasing the number of channels per transponder, Titan will decrease the 
channel tuning and occupancy to [...***...] per carrier.  With this spacing, 
the number of channels per transponder could potentially be increased to 
[...***...] channels per transponder if link budget restrictions and maximum 
satellite power restrictions could be met.

    The number of channels that can be supported on a transponder is limited 
by several factors such as satellite power limits, rain fade, 
inter-modulation products, local interference, and adjacent channel 
interference.  The combined effects of these, and how much margin must be 
designed into the link budget to account for them, can be most accurately 
measured by gathering data from a system after it is running with a large 
volume of traffic.  Therefore, Titan is proposing that the system be operated 
with [...***...] channels per transponder and then analyze the results and 
determine if it is practical to operate the system with more than [...***...] 
channels per transponder.

    Titan plans to have this development available in January 1998.
