                                                       September 18, 1997

                             MEMORANDUM OF UNDERSTANDING


This Memorandum of Understanding presents the agreements reached between UCOM
and Titan Information Systems ("Titan") during discussions held at UCOM's
Headquarters in Bangkok Thailand, during the period September 16 through 18,
1997, concerning Titan's performance on the BAAC Project.

          1.   Titan recognizes that it has been late in delivering hardware and
               software that meets contract specifications and that this has
               caused serious difficulties for UCOM on the BAAC project. To
               resolve issues related to the Equipment Purchase Agreement dated
               27 June 1996 (the "Contract") [...***...] Titan agrees 
               [...***...]
          2.   To accomplish the intent of 1. above, future payments from UCOM
               to Titan for deliveries against the existing Contract will be
               [...***...] specified in the Contract. Additionally, the final
               payment made under this Contract will be [...***...] of the 
               amount of money already paid to Titan to date, in conjunction 
               with this contract [...***...]

          3.   UCOM agrees to pay Titan for product that it has already shipped
               to Thailand, but for which it has not yet been paid, in
               accordance with the following terms:
                    a)   UCOM will make an initial payment via bank transfer by
                         September 24, 1997 if possible and by September 30,
                         1997 at the latest, [...***...] for product already
                         shipped but not yet paid by UCOM. as follows:

                         [...***...]


                    b)   UCOM will make final payment of [...***...] as soon as
                         all 64 of the modems which have already been delivered,
                         are [...***...] capability and tested to prove proper
                         operation.

          4.   Titan expects to ship an additional 36 modems, capable of 80 MHz
               operation, by the end of September, 1997. Titan will extend up to
               [...***...] payment terms to UCOM on this shipment to provide 
               time for UCOM to deal with any special requirements that may be 
               imposed by the Thai Government because of the national monetary
               crisis.

          5.   Titan agrees to promptly initiate application for an American
               EX/IM Bank loan facility which would be used by UCOM to buy Titan
               and possibly other American products required for the BAAC
               project, if UCOM requests such assistance.
