1.  PTTEP and its Subsidiaries’ Petroleum Reserves Report As of December
    31, 2006

The total Proved Reserves of PTT Exploration and Production Public
Company Limited (PTTEP) and its Subsidiaries as of December 31, 2006 are
shown in the attached table. The Proved Reserves are reviewed annually
by company’s earth scientists and reservoir engineers to ensure rigorous
professional standards. The Proved Reserves are reported on a gross
basis, which includes the company’s net working interest and related
host country’s interest.

No reserve quantities have been recorded for the company on Blocks B,
48/95, 52/97, 16-1 Projects in offshore Vietnam, Block G4/43 in Gulf of
Thailand, Myanmar M7&M9 in Gulf of Mataban and Block 433a&416b in
Algeria because no commercial arrangement has been established for the
discoveries.

The total Proved Reserves (Consolidated Companies) as of December 31,
2006 of PTTEP and its subsidiaries are 156 Million Stock Tank Barrels
(MMSTB) for crude oil and condensate, and 5,001 Billion Standard Cubic
Feet (BSCF) for gas. The total Proved Reserves (Consolidated Companies)
in term of oil equivalent is 923 Million Barrels (MMBOE).

The total production in 2006 (Consolidated Companies) is 71 MMBOE or
equivalent to the production rate of approximately 194,000 Barrels of
Oil Equivalent per Day (BOED), approximately 10,000 BOED or 5% increase
from last year. The production increase was mainly attributed to the
increase of petroleum production from B8/32 & 9A, Pailin, and Bongkot
projects, the initially putting on production from Phu Horm and Oman 44
project in 2006.

(1) The Proved Reserves are reported on a gross basis which includes the
    company's net working interest and the related host country
    interest.

(2) Includes JDA Project

(3) Waterflooding techniques in S1 project.

(4) PTTEP discovers and plan to develop the new proved reserves in
    Bangkot project, Oman 44 project, and Vietnam 9-2 project.

 2. Capitalized costs relating to oil and gas producing activities

Capitalized costs represent cumulative expenditures for proved and
unproved properties, and support equipment and facilities used in oil
and gas exploration and production operations together with related
accumulated depreciation, depletion and amortization.

Proved properties include exploration & development wells, equipment,
transportation pipeline and related producing facilities associated with
proved reserves project. Unproved properties represent amounts
associated with non-proved reserve project. Support equipment and
facilities include warehouse, field offices, vehicles and movable assets
used in oil and gas producing activities.

The net capitalized costs represent the undepreciated value for these
assets.

5. Standardized Measure of Discounted Future Net Cash Flows Relating to
Proved Oil and Gas Reserves

The standardized measure of discounted future net cash flows, related to
the above proved oil and gas reserves, is computed by applying year-end
prices of oil and gas (with consideration of price changes only to the
extent provided by contractual arrangements) to the estimated future
production of year-end proved oil and gas reserves remaining less
estimated future expenditures (based on year-end costs) to be incurred
in developing and production the proved reserves, discounted using a
rate of 10% per year to reflect the estimated timing of the future cash
flows. Future income taxes are calculated by applying the appropriate
year-end statutory tax rates to the future pre tax net cash flows and
reduced by applicable tax deductions or tax credits.

Discounted future cash flow estimates like those shown below are not
intended to represent estimates of the fair value of oil and gas
properties. Estimates of fair value should also consider probable and
possible which may become proved reserves in the future, anticipated
future oil and gas prices, interest rates, changes in development and
production costs and risks associated with future production. Because of
these and other considerations, any of fair value is necessarily
subjective and imprecise.
