The specific fields from which the Other Contract Gas will be committed, as well as the quantities committed from each field, will be identified in the Supplemental Memorandum. 2.4 The amounts of net natural gas constituting the VICO Contract Gas and the Other Contract Gas are part of the estimates of proved recoverable reserves of natural gas to be certified by the independent petroleum consultant firm of DeGolyer and MacNaughton in written statements based on data available on December 31, 1991. The quantities for the VICO Contract Gas and the Other Contract Gas and the Producers' Percentage set forth in Sections 2.2 and 2.3 were established by PERTAMINA in its letter dated December 20, 1989 (No. 1852/D0000/89.S1) to be used only on a provisional basis until such time as DeGolyer and MacNaughton certify such reserves, following which the identity of the participating fields and the quantities in each field which comprise the VICO Contract Gas and the Other Contract Gas and the Producers' Percentage shall be adjusted and documented in the Supplemental Memorandum in accordance with the Memorandum of Understanding Re: Supply Agreements and Package IV Sales, of even date herewith, by and among PERTAMINA, Contractors and the production sharing contractors in the Other Contract Areas. 2.5 Upon completion of the adjustments provided for in Section 2.4, but not later than the date of loading the initial cargo of LNG for delivery under the Badak IV LNG Sales Contract, PERTAMINA and Contractors shall execute an addendum to this Supply Agreement confirming the VICO participating fields, the quantities in each field which comprise the VICO Contract Gas and the Other Contract Gas and the Producers' Percentage.
