HIGHLIGHTS

In this report, quarterly comparisons are first quarter 2011 compared to first
quarter 2010 unless otherwise noted. The results of Petrominerales Ltd.
("Petrominerales") (TSX:PMG), previously majority owned by Petrobank, have been
separately disclosed as discontinued operations up until December 31, 2010, the
date this business unit was spun off to Petrobank shareholders.




Q1 2011 Financial Highlights                                                

--  Funds flow from continuing operations increased eight percent to $168.4
    million, or $1.58 per basic share, compared to the fourth quarter of
    2011 primarily as a result of PetroBakken's higher operating netbacks. 
--  PetroBakken's operating netback (excluding hedging activity) of $52.42
    per barrel of oil equivalent ("boe") increased nine percent, compared to
    the fourth quarter of 2010, primarily as a result of higher pricing, and
    decreased slightly by one percent from the prior year period, primarily
    due to increased production expenses. 
--  Net income attributable to Petrobank shareholders from continuing
    operations increased $20.3 million to $20.6 million in the first quarter
    of 2011 compared to the first quarter of 2010. The increase is due
    mainly to a non-cash gain arising from the revaluation of PetroBakken's
    convertible debentures derivative financial liability. 
--  Capital expenditures were $361.7 million in the first quarter, up 73
    percent from a year ago and 20 percent from the fourth quarter of 2010.
    The increases were primarily driven by PetroBakken's aggressive drilling
    program and extensive facility investments, and the Heavy Oil Business
    Unit's 10 well-pair expansion project at Kerrobert. 
--  On January 4, 2011, Petrobank entered into a new three year $200 million
    credit agreement with a syndicate of lenders. 

Heavy Oil Business Unit 2011 Operations Highlights                          

--  Start up of Kerrobert expansion project is on schedule with the first of
    the new production wells being tied into the central processing
    facility. 
--  A five year collaboration agreement has been signed with Pemex
    Exploracion y Produccion, a subsidiary entity of the Mexican state oil
    company Petroleos Mexicanos ("Pemex"), as the first step to licensing
    our THAI(R) technology in Mexico. 
--  We have acquired and agreed to acquire a further seven sections of land
    in Saskatchewan on the Kerrobert Waseca channel trend. 
--  Our Dawson demonstration project is moving forward and we anticipate
    starting to drill in the third quarter of 2011. 
--  The Kerrobert demonstration project production averaged 110 barrels of
    oil per day ("bopd") for the first quarter and the two wells are now
    being prepared to be tied into the new production facility. 



Kerrobert Project

The Kerrobert expansion project has been commissioned and the central processing
facility ("CPF") is ready to accept production. Drilling and completion of the
10 air injection wells is complete, nine of the new horizontal production wells
are drilled, with five completed and the remaining five on schedule to be
completed and tied in by June 30. 


We had anticipated the Pre-Injection Heating Cycle ("PIHC") in the new wells to
take up to 60 days; however temperature response was achieved in less than
twenty days, which allowed us to accelerate air injection operations. Air
injection began on three injector wells on the first pad in April. The two
remaining wells on this pad are near the end of their PIHC and will be on air
before the end of May. We expect to begin the PIHC in the injector wells on the
second pad by mid-June. All production will be brought into the CPF as the wells
come on-stream, including the two original wells from the demonstration project.
The production wells are all on schedule to be producing into the CPF by
mid-July.


We are pleased with the final placement of the injection and production wells as
they were drilled within our new design parameters. The new production wells are
larger in diameter, have a higher open flow area to the reservoir, a tighter
mesh in the FacsRite(TM) screen for improved solids control and an improved
wellhead configuration, all of which are expected to result in improved
production and operating capability.


Capital costs for the 10 well-pairs and facilities expansion are estimated at
approximately $95 million versus an original budget of approximately $75
million. Pipeline and facilities costs are on budget and on schedule. Drilling
and completion costs exceeded budget primarily related of the horizontal
production wells. The start-up of the drilling program was behind schedule due
to mechanical and operating problems with the drilling rig, and one well had to
be re-drilled due to intermediate casing failure while cementing. The completion
costs of the injection and production wells are on budget. 


During the first quarter of 2011, the initial two wells' production was
approximately 110 bopd. Operations on the initial two wells were impacted by the
drilling and construction activities related to the expansion. During April,
road bans and limited access due to expansion drilling activities resulted in
lower on-stream times with production averaging 105 bopd.


Dawson Project

We received final Energy Resources Conservation Board ("ERCB") and Alberta
Environment ("AENV") approval for our initial Dawson project during the fourth
quarter of 2010. The Dawson project will initially consist of two THAI(R)
well-pairs plus associated surface facilities.


Field activities conducted during the first quarter of 2011 included drilling
two stratigraphic wells that were cored to confirm seismic contours and the
drilling of two ground water monitoring wells. Our plan is to start construction
of access roads and leases late in the second quarter while drilling and
completion activities will begin in the third quarter of 2011. 


We will move the surface facilities from our first two wells at the Kerrobert
project to our Dawson project in the third quarter of 2011. PIHC is planned to
commence in the fourth quarter of 2011. Production is also expected to commence
in the fourth quarter.


In order to capitalize on the full potential at Dawson, the environmental
assessment and regulatory application associated with the Dawson expansion is
underway. The Dawson expansion project is being designed as a 10,000 bopd
capacity project and the required regulatory applications for both the ERCB and
AENV are scheduled to be submitted during the third quarter of 2011. We expect
the regulatory review cycle could take up to 18 months.


Conklin Demonstration Project

As part of our on-going evaluation of our Conklin operations, we have abandoned
the original three wells that were previously shut-in as well as P2B and P3B.
During the first quarter of 2011, we observed that the P1B well, where the toe
was drilled well short of the combustion zone, is beginning to heat up. We are
in the process of evaluating the multi-THAI(R) configuration, adding another air
injector on P1B further along this well bore and drilling a new production well
in a better part of the reservoir. 


With our Kerrobert and Dawson projects moving forward, we are now primarily
evaluating options for the Conklin demonstration project as a field scale
testing site for future technology enhancements to the THAI(R) process. 


May River Project

The May River application is proceeding through the regulatory process. We have
responded to all of the information requests and have recently filed our final
response to the three Statements of Concerns ("SOC") with the ERCB. We do not
believe that the SOCs have merit to warrant the granting of standing; however
this decision rests with the ERCB.


During the first quarter of 2011, we drilled 11 oil sands evaluation wells to
further evaluate resource potential and further delineate the resource for
future expansion phases of the May River property. Based on internal estimates
these wells added approximately 40 million barrels of best estimate contingent
resource and we have asked our external reserve evaluator, McDaniel & Associates
Consultants Ltd., to update our 2010 reserve report to reflect these drilling
results. 


Archon Technologies Ltd. ("Archon")

Archon, our wholly-owned technology subsidiary, continues to advance our suite
of technologies, including a novel process to remove H2S in the produced gas
stream that will further enhance our CrystaSulf(TM) process. We plan to field
test this technology during 2011. Our ongoing research and development efforts
have identified new technologies and enhancements to existing intellectual
property that could result in as many as eight new patents in the coming year
which will serve to further strengthen and improve our core THAI(R) and CAPRI(R)
patents. 


During the first quarter, we signed a five year non-commercial general
collaboration agreement concerning research, scientific, technological and human
resources development with Pemex Exploracion y Produccion ("PEP"), a subsidiary
entity of the Mexican state oil company, Pemex. This agreement provides for the
sharing of scientific and technological information, pursuant to the regulations
in force, and the evaluation of enhanced oil recovery technologies for heavy oil
deposits in Mexico. This agreement is an important first step in a possible
negotiation, under Mexican law, of a licensing deal that will permit PEP to
utilize Petrobank's THAI(R) technology. 


Land Acquisitions

As previously reported Petrobank acquired 3.5 sections (2,240 acres) of
petroleum and natural gas rights at a Saskatchewan Crown Sale in late 2010. The
lands are located in the Plover area on the same trend as our Kerrobert project.
During the first quarter we purchased 3-D seismic and we plan to drill a
stratigraphic well later in 2011 to define the resource potential. 


Petrobank closed an acquisition on March 31, 2011 to acquire 6.5 sections (4,160
acres) of petroleum and natural gas rights. These lands are situated two miles
southeast of the acquired Plover lands, and are also located on the same trend
as Kerrobert.

PETROBANK'S LIQUIDITY AND CAPITAL RESOURCES

Petrobank and PetroBakken manage their capital structure independently and
generate their own cash flows, and have the ability to fund their operations
through the issuance of secured and unsecured debt as well as equity financing.
Petrobank's capital resources are focused on funding corporate and Heavy Oil
Business Unit expenditures. At March 31, 2011, independent of PetroBakken,
Petrobank on a standalone basis had a working capital deficit of $28.7 million
and available credit capacity of $196.2 million.


Based on Petrobank's current ownership and PetroBakken's intentions of paying an
annual dividend of $0.96 per PetroBakken share, Petrobank expects to receive
$105 million of dividends annually from PetroBakken, paid monthly. Petrobank can
also raise funds by selling a portion of its ownership in PetroBakken or by
issuing additional debt secured by this interest.


Petrobank expects to sufficiently fund our HBU capital expenditure program with
available credit, cash from operations and dividends received from PetroBakken.

Non-GAAP Measures: This press release contains financial terms that are not
considered measures under generally accepted accounting principles ("GAAP"),
such as funds flow from continuing operations, funds flow per share and
operating netback. These measures are commonly utilized in the oil and gas
industry and are considered informative for management and shareholders.
Specifically, funds flow from continuing operations and funds flow per share
reflect cash generated from operating activities before changes in non-cash
working capital. Management considers funds flow from operations and funds flow
per share important as they help evaluate performance and demonstrate the
Company's ability to generate sufficient cash to fund future growth
opportunities and repay debt or financing obligations. Profitability relative to
commodity prices per unit of production is demonstrated by an operating netback.
Funds flow from continuing operations, funds flow per share and operating
netbacks may not be comparable to those reported by other companies nor should
they be viewed as an alternative to net income or other measures of financial
performance calculated in accordance with GAAP.


The following table shows the reconciliation of funds flow from continuing
operations to cash flow from operating activities from continuing operations for
the periods noted (in $000s):

Contingent Resources: In this press release, Petrobank has disclosed estimated
volumes of "contingent resources". "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. In respect of the May River
project, contingencies include current uncertainties around the specific scope
and timing of the development of the project; lack of regulatory approvals;
uncertainty regarding marketing plans for production from the subject area; and
need for improved estimation of project costs. Contingent resources do not
constitute, and should not be confused with, reserves. There is no certainty
that it will be commercially viable to produce any portion of the contingent
resources on the May River property.


Forward-Looking Statements: Certain information provided in this press release
constitutes forward-looking statements. Specifically, this press release
contains forward-looking statements relating to financial results, results from
operations, the timing of certain projects, future resource potential, potential
technology enhancements and sources of available financing. 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 forecasted. 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.


Natural gas volumes have been converted to barrels of oil equivalent ("boe").
Six thousand cubic feet ("Mcf") of natural gas is equal to one barrel of oil
equivalent based on an energy equivalency conversion method primarily
attributable at the burner tip and does not represent a value equivalency at the
wellhead. Boes may be misleading, especially if used in isolation.
