(1) Gross reserves and/or resources include the working interest
    reserves/resources before deductions of royalties payable to others.
(2) Possible reserves are those additional reserves that are less certain
    to be recovered than probable reserves.
(3) Contingent resources, as evaluated by McDaniel, are those quantities of
    bitumen estimated to be potentially recoverable using SAGD technology
    from known accumulations but are classified as a resource rather than
    a reserve primarily due to the absence of regulatory approvals,
    detailed design estimates and near term development plans and are in
    addition to 3P reserves.
(4) A low estimate means higher certainty (P90), a best estimate (P50)
    means most likely and a high estimate means lower certainty (P10).

McDaniel & Associates Consultants Ltd. (McDaniel THAI(TM) Transition Report)

The McDaniel estimates are based on SAGD technology as it is the presently
recognized technology used to define in-situ oil sands reserves and resources.
This does not in any way reflect the technical merits of the THAI(TM) process.
To be able to establish the technical basis to assign reserves and resources
based on THAI(TM), McDaniel conducted a rigorous analysis of our Conklin
THAI(TM) project in conjunction with the reserve evaluation. This analysis
encompassed all of the operational and observational data from the inception of
the Conklin project to clearly establish the effectiveness and sustainability of
THAI(TM) as an economic recovery process. The first step of the analysis was to
define the exploitable resource base on the lands using THAI(TM) and to then set
out the parameters to assign reserves and resources. The Transition Report
concludes that, "It is the opinion of McDaniel & Associates that the pilot
project is successfully proving the THAI(TM) process". In addition, THAI(TM)  is
an effective recovery process that is able to produce bitumen from a greater
portion of the reservoir than SAGD, specifically the thinner and less homogenous
regions. The SAGD exploitable bitumen on our lands is estimated by McDaniel to
be 1.3 billion barrels in the low case and 1.7 billion barrels in the high case.
The Transition Report assigns exploitable bitumen-in-place for THAI(TM) of 1.6
billion barrels in the low case and 2.0 billion barrels in the high case, or 21
and 15 percent higher than SAGD respectively. Now that a THAI(TM) exploitable
bitumen-in-place has been defined, McDaniel has confirmed that they will issue a
THAI(TM) based reserves and resource estimate at Conklin once commercial
production rates ( greater than 250 bbls/day per well) has been sustained for a
period of at least three months.


The conclusion from the Transition Report confirms that the THAI(TM) process is
an effective production technology. The analysis is also applicable to
Kerrobert, Dawson, and other similar reservoirs. Now that we have established
the technical baseline for THAI(TM), we will intensify our efforts to sustain
commercial production rates, enabling the assignment of THAI(TM) reserves and
resources to our current and future projects.

THAI(TM) BENEFITS

THAI(TM) has many potential benefits over SAGD including expected higher
resource recovery (70%-80% versus 30%-50% for SAGD), lower production and
capital costs, minimal usage of natural gas and fresh water, a partially
upgraded crude oil product, reduced diluent requirements for transportation, and
lower greenhouse gas emissions. The THAI(TM) process also has the potential to
operate in lower pressure, lower quality, thinner and deeper reservoirs than
current steam-based recovery processes. The continued field demonstration of
THAI(TM) will have an enormous impact on resource recovery and estimates of
reserve volumes.


Petrobank has created an educational video to provide interested viewers the
opportunity to see THAI(TM) in action, where we've been, and where we're going.
We encourage you to view this newly produced video at

HEAVY OIL BUSINESS UNIT OPERATIONAL UPDATE

Kerrobert Project

At Kerrobert, during the months of January and February, we adjusted our pump
configuration and were able to achieve more consistent well operations; however,
these pumps are still not able to fully draw down the wells. Production rates in
early March, based on field measurements, have averaged 123 barrels of oil per
day ("bopd"), with an on-stream factor of 81%. Well bore temperatures are now
consistently in the 250 to 350 degrees Celsius range, and produced gas
composition confirms high temperature combustion. We have now started to see an
improvement in the API and viscosity of the produced oil.


Surface facilities have been operating smoothly with only minor cold weather
related issues. In operations to date we have not had any solids or produced
sand. The next expansion of our air compression capacity will be installed at
the beginning of April. We are finalizing our plans for the development of the
initial earned lands which would encompass nine additional production wells in
this portion of the pool. We are planning to have the additional wells operating
in the third quarter of 2010.


We are now proceeding with the replacement our current hydraulic pump
configuration originally conceived to only operate during startup. As previously
reported, we have concluded that permanent pumps will be more effective than
relying on produced gas-lift alone. After careful analysis for this production
phase in the well life, we have specified and ordered a new pumping solution
that should help us meet our production targets without relying on gas-lift. New
wellheads, instrumentation, and pumps have been ordered, and will be installed
by the end of March.


Conklin Pilot Project

At Conklin, we have now identified an alternative completion and production
configuration for the current wells based on knowledge gained recently from our
operations at Kerrobert. This alternative configuration will involve the
addition of pumps and a revised production gas string in each of the wells. We
have recently shut in the P2B and P3B wells to prepare these wells for the
reconfiguration, which will take place over the next three months and will
involve recompleting each of the current wells. The revised completion design is
expected to improve the production characteristics of the wells enabling them to
flow more uniformly by reducing the effects of swings in gas production inherent
with the current produced gas-lift mechanism. This is a significant optimization
step that is expected to improve and stabilize production over the long term and
that we intend to utilize in all future projects. The P1B well is currently
producing at approximately 135 bopd and will also be reconfigured after the P2B
and P3B recompletions. Once the well workovers are completed, we expect to ramp
up Conklin project production to our 1,500 bopd target during the second half of
2010.


May River Project

We plan to have 12 additional OSE stratigraphic test wells and 3D seismic over
the May River project area completed by the end of March. This work will further
delineate the reservoir over the project area and allow us to finalize well
placement and areas for future expansion. The 3D seismic will also be acquired
over the current Conklin project to provide a new 4D view of the progress of the
combustion zone. Processing and interpretation will be carried out during the
second quarter of 2010.


The regulatory application for May River's first phase was filed with the Energy
Resources and Conservation Board ("ERCB") and Alberta Environment in December
2008. The first round of supplemental information requests ("SIRs") from Alberta
Environment and the ERCB were responded to in mid-December 2009. A second round
of SIRs were received from Alberta Environment early in 2010 and we have
submitted our responses. Typically the ERCB also submits a second round of SIRs
but none have been received to-date.


Front end engineering and design for the project was completed in the fourth
quarter of 2009, and we are now developing the cost estimate and initiating
procurement for some of the long lead time equipment. The design incorporates
power generation utilizing low energy produced gas, sulphur recovery, is CO2
capture ready, and will be a net water producer rather than a water user, making
our May River project a leading environmentally sustainable benchmark for oil
sands and heavy oil development. The project utilizes a modular approach that is
designed to be installed and operated on heavy oil projects world-wide.


Dawson Project

Dawson is a joint venture project located near Peace River, Alberta with a
significant heavy oil resource in the Bluesky formation. The regulatory
application for this project was filed on April 2, 2009 contemplating a project
of similar scope and scale to our Kerrobert project. We received Alberta
Environment's conditional approval on June 26, 2009. The ERCB's SIRs were
received at the end of November and we have submitted our responses.


Archon Technologies

Our wholly-owned subsidiary, Archon Technologies Ltd., has tested several
innovative and step-change technologies on a lab scale. These could
significantly improve THAI(TM) performance by improving overall recovery and
quality of produced heavy oil. Small scale field pilots for these technologies
are planned to be implemented at Conklin. We recently filed another new
enhancement patent involving a novel well design bringing our portfolio of
patents to eight.


We continue to receive world-wide interest in our technology because of its
superior economic and environmental benefits. Our joint venture strategy is to
demonstrate and commercialize THAI(TM) and CAPRI(TM) in a wide range of large
global resource opportunities.


PETROBAKKEN (64% OWNED BY PETROBANK)

CORPORATE PRESENTATIONS

The Petrobank, PetroBakken and Petrominerales corporate presentations have been
updated and can be found at www.petrobank.com, www.petrobakken.com, and
www.petrominerales.com.


Petrobank Energy and Resources Ltd. is a Calgary-based oil and natural gas
exploration and production company with operations in western Canada and Latin
America. The Company operates high-impact projects through three business units
and a technology subsidiary. The Canadian Business Unit, operated by Petrobank's
64% owned TSX-listed subsidiary, PetroBakken Energy Ltd. (TSX:PBN), is a premier
light oil production company combining high growth, long-life Bakken reserves
and production with legacy conventional light oil assets, delivering industry
leading operating netbacks, strong cash flows and production growth. The Latin
American Business Unit, operated by Petrobank's 66% owned TSX listed subsidiary,
Petrominerales Ltd. (TSX:PMG), is a Latin America-based exploration and
production company producing oil in Colombia with 14 exploration blocks covering
a total of 1.8 million acres in the Llanos and Putumayo Basins and 2.6 million

Forward-Looking Statements: Certain information provided in this press release
constitutes forward-looking statements. The words "anticipate", "expect",
"project", "estimate", "forecast" and similar expressions are intended to
identify such forward-looking statements. Specifically, this press release
contains forward-looking statements relating to financial results, results from
operations and the timing of certain projects. The reader is cautioned that
assumptions used in the preparation of such information, although considered
reasonable at the time of preparation, may prove to be incorrect. Actual results
achieved during the forecast period will vary from the information provided
herein as a result of numerous known and unknown risks and uncertainties and
other factors. You can find a discussion of those risks and uncertainties in our
Canadian securities filings. Such factors include, but are not limited to:
general economic, market and business conditions; fluctuations in oil prices;
the results of exploration and development drilling, recompletions and related
activities; timing and rig availability, outcome of exploration contract
negotiations; fluctuation in foreign currency exchange rates; the uncertainty of
reserve estimates; changes in environmental and other regulations; risks
associated with oil and gas operations; and other factors, many of which are
beyond the control of the Company. There is no representation by Petrobank that
actual results achieved during the forecast period will be the same in whole or
in part as those forecast. Except as may be required by applicable securities
laws, Petrobank assumes no obligation to publicly update or revise any
forward-looking statements made herein or otherwise, whether as a result of new
information, future events or otherwise.


Resources and Contingent Resources: In this press release, Petrobank has
disclosed estimated volumes of "contingent resources" or "resource" estimates.
"Resources" are oil and gas volumes that are estimated to have originally
existed in the earth's crust as naturally occurring accumulations but are not
capable of being classified as "reserves". The following are excerpts from the
definition of "contingent resources" as contained in Section 5 of the COGE
Handbook, which is referenced by the Canadian Securities Administrators in
"National Instrument 51-101 Standards of Disclosure for Oil and Gas Activities".
"Contingent resources" are those quantities of petroleum estimated, as of a
given date, to be potentially recoverable from known accumulations using
established technology or technology under development, but which are not
currently considered to be commercially recoverable due to one or more
contingencies. Contingencies may include factors such as economic, legal,
environmental, political, and regulatory matters, or a lack of markets. It is
also appropriate to classify as "contingent resources" the estimated discovered
recoverable quantities associated with a project in the early evaluation stage.
"Contingent resources" are further classified in accordance with the level of
certainty associated with the estimates and may be sub classified based on
project maturity and/or characterized by their economic status. "Resources" and
"contingent resources" do not constitute, and should not be confused with,
reserves.


Possible Reserves: Possible reserves are those additional reserves that are less
certain to be recovered than probable reserves. There is a 10% probability that
the quantities actually recovered will equal or exceed the sum of proved plus
probable plus possible reserves.


Net Present Values: Estimated values of future net revenue disclosed in this
press release do not necessarily represent fair market values.


Aggregation of Reserves and Resources: Certain tables in this press release
contain volumes that are an arithmetic sum of multiple estimates of reserves and
resources, which statistical principles indicate may be misleading as to volumes
that may actually be recovered. Readers should give attention to the estimates
of individual classes of reserves or resources and appreciate the differing
probabilities of recovery associated with each class of reserves and resources,
as discussed herein, and as discussed in our Annual Information Form which will
be filed on the SEDAR website at www.sedar.com later in March.


Barrels of Oil Equivalent: Disclosure provided in this press release in respect
of barrels of oil equivalent ("boe") units may be misleading, particularly if
