1. L53-A structure, excluding the volume located within the PTTEP 2 km2
   production license acreage surrounding the BP-1 well drilled in the
   1980's.
2  Volumes reflect Pan Orient Energy Corporation's 100% working interest in
   the L53/48 Concession.
3  Volumes include royalties due to other parties.
4  Contingent Resources are a sub-classified under the "Development Pending"
   category of project maturity. 
5  Resources are contingent on Pan Orient receiving the proposed 2 km2
   Production License
6  Resources are contingent on Pan Orient receiving an additional Production
   License covering this area

1 Resources assessed at forecast crude oil reference prices and costs.
2 The reference price for crude oil per barrel (US$ WTI per barrel) is
  $80.00 for 2010, $83.60 for 2011, $87.40 for 2012, $91.30 for 2013, $95.30
  for 2014, $99.40 for 2015, and prices increase at 2% per year thereafter.
3 Oil revenue for these resources is equal to approximately 92% of the
  forecast crude oil reference price.
4 Development of the proposed production license area includes eight wells
  and one water disposal well with a development cost of US$8.8 million.
5 The engineered values disclosed may not represent fair market value.



This resource certification relates to the Pan Orient L53-A discovery well in
2009. The L53-A structure is a sandstone reservoir with four stacked sandstone
zones. The proposed Pan Orient two square kilometer Production License offsets a
two square kilometer production license acreage owned by PTTEP which surrounds
the BP-1 well which was drilled in the late 1980's, and which has produced
approximately 330,000 barrels of oil.


In preparation for the development of the resources estimated in the GCA report,
Pan Orient is in the process of preparing the Production License ("PL")
Application covering two square kilometers of the L53-A structure that is
anticipated to be submitted to the Thailand Department of Mineral Fuels ("DMF")
in short order, this being the purpose for this mid year resource assessment /
engagement of GCA by Pan Orient.


In consideration of the preliminary status of the development and the pending
submission of a PL application, the contingent volumes for L53-A estimated in
the GCA report are classified under the "development pending" subcategory of
contingent resources. Pan Orient has no reason to believe this development
application will not be approved by the DMF and anticipates the PL application
to be approved within approximately 90 days of submission to the DMF. The
company has produced over 13,500 barrels of 28.7 degree API crude oil from the
L53-A well during the 90 day production test which concluded on April 2, 2010.
This crude oil is being stored in tanks until a PL is approved. Upon approval of
the PL, the crude oil will be sold, the L53-A well will be brought back
on-stream and additional development of the pool will commence in 2010.


Pan Orient is a Calgary, Alberta based oil and gas exploration and production
company with operations currently located onshore Thailand, Indonesia and in
Western Canada.

results, expectations, achievements or performance to differ materially,
including without limitation: imprecision of reserve estimates and estimates of
recoverable quantities of oil, changes in project schedules, operating and
reservoir performance, the effects of weather and climate change, the results of
exploration and development drilling and related activities, demand for oil and
gas, commercial negotiations, other technical and economic factors or revisions
and other factors, many of which are beyond the control of Pan Orient. Although
Pan Orient believes that the expectations reflected in its forward-looking
statements are reasonable, it can give no assurances that the expectations of
