**3.**               The performance of revision can be initiated by oneof the Parties within the validity term of the current Agreement on thecondition of observance of statue of limitation established by current law ofthe Russian Federation.

**4.**               The basis for the beginning of the datareconciliation actions is the discrepancy between summary volume or costfigures on the services rendered during the Accounting period (in accordancewith the data of Rostelecom and the Operator), exceeding 3 (three) %.

**5.**               The following actions can be performed in thereconciliation:

----

 

·                  Thereconciliation of data submitted by Rostelecom and the Operator,

·                  detailedreconciliation

·                  comprehensivetechnical study;

6.                             The reconciliation of data submitted byRostelecom and the Operator:

6.1.          The Party initiating the revision forms andsubmits to the other Party the report in the form of Table 1 presented in thisAppendix.

6.2.          The Party receiving the report indicated inpar. 6.1, performs counter-analysis of the execution of the conditionshereunder in the billing:

·                  minimal  non-tariff limit of the calls,

·                  typeof the traffic round-off,

·                  tariffs.

·                  criteriaof traffic accounting (switching, trunks, numbering capacity).

6.3.          If as a result the Party has detected a mistakeand its correction has eliminated the discrepancies, the Parties agree on thedate of correction of the mistake and the date of re-calculation in accordancewith the conditions hereof.

6.4.          If the mistake was not detected and itscorrection did not effect the elimination of the discrepancies, the Partyinitiating the revision chooses the directions (no more than five (5)) forwhich the maximal discrepancies were detected, the volumes must be sufficientfor the performance of revision. The data shall be input into Table 2 attachedherein.

The other Party, no later thanwithin 5 (five) days upon receipt of the report draws up the Act on the resultsof the counter-analysis and submits it to be approved by the cooperating Party.

7.                             Detailed reconciliation

7.1.          The basis for the beginning of a detailedreconciliation is the coordinated at the previous stage acts and reports on thecondition of absence of detected causes of discrepancies.

7.2.          The Parties adjust the following parameters ofthe detailed reconciliation:

·                  timefactors (month, week, day, hour and so on),

·                  ancillaryparameters (switchboards, trunks, numbering capacity),

·                  aspectof the detailed reconciliation,

·                  sizeof the detailed reconciliation,
