3.5.3  Failure shall be deemed to have occurred if there is a continuous and
       uninterrupted breakdown of the Service, or there is a continuous and
       uninterrupted period during which the Service fails to meet the Service
       Description or there is a continuous and uninterrupted period during
       which there is a significant degradation of the quality of the Customer's
       signals, (excluding degradation caused by severe rainfall at the uplink
       site) transmitted via the Service lasting for half an hour or more. The
       length of any such breakdown or period shall be measured from the time

       a breakdown or problem until the Service is restored.

                                                                    Page 8 of 19
<PAGE>

       the month following the Failure and shall be deducted from such
       Charges.

       is suspended for the following reasons:-

       3.5.7.1  KSS needs to carry out work relating to upgrading or maintenance
                of the Service provided KSS has given to the Customer in writing
                the maximum period of notice reasonably practicable in the
                circumstances and has used its reasonable endeavours to agree
                with Customer a suitable time for such work to be carried out;
                or

       3.5.7.2  KSS and GE Americom are reasonably of the opinion that any act
                or default of the Customer or its other contractors is likely to
                cause damage to GE-lE or any other use of the satellite and have
                given notice by telephone to Customer either beforehand or,
                where this is not practicable, used all reasonable endeavours to
                communicate the information within one half hour of the
                suspension.

       3.5.7.3  if a Failure arises from the Customer not agreeing to KSS
                carrying out upgrading or maintenance work then KSS will have no

       the Customer for breach of this Contract.
