(FAS 69) and other information - Unaudited

(A) PTTEP and its Subsidiaries’ Petroleum Reserves Report As of December
    31, 2008

The total Proved Reserves of PTT Exploration and Production Public
Company Limited (PTTEP) and its Subsidiaries as of December 31, 2008 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 hydrocarbon discoveries
in Vietnam Blocks B, 48/95 and 52/97, and Myanmar M9 in the Gulf of
Mataban since no Gas Sale Agreement (GSA) has been established.

The total Proved Reserves (Consolidated Companies) as of December 31,
2008 of PTTEP and its Subsidiaries are 201 Million Stock Tank Barrels
(MMSTB) for crude oil and condensate, and 4,770 Billion Standard Cubic
Feet (BSCF) for gas. The total Proved Reserves (Consolidated Companies)
in term of oil equivalent are 944 Million Barrels (MMBOE).

The total production in 2008 (Consolidated Companies) is 90.6 MMBOE (24
MMSTB for crude and condensate, and 401 BSCF for gas) or the production
rate of approximately 247,700 Barrels of Oil Equivalent per Day (BOED).
The increase is approximately 38,700 BOED or 18% higher than that of
last year. The production increase was mainly attributed to the new
petroleum production from Vietnam Block 9-2 and Arthit projects.

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

(B) 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, amortization and impairment.

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.

(E) 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.

  27.08 $/bbl from that of last year
