OPERATIONAL REVIEW

Petrobank reported strong funds flow from operations of $150.4 million, or $1.64
per diluted share, in the second quarter of 2009 as year over year sales volumes
increased by 72% to 41,127 boepd. Funds flow from operations decreased by 15%
from the prior year, primarily due to a 52% decrease in world oil prices. CBU
infrastructure investments in 2008 helped reduce operating expenses to $6.52/boe
in the second quarter, preserving strong operating netbacks of $42.72/boe,
excluding hedging gains of $3.46/boe. Similarly in Colombia, continued
improvements in production operations resulted in operating expenses decreasing
to $7.86/bbl, leading to operating netbacks of $42.88/bbl. 


PETROBAKKEN

On August 4, 2009, Petrobank and TriStar agreed to a strategic combination of
TriStar and Petrobank's CBU. The combination will create a new publicly listed
company, PetroBakken, that will be a premier, Bakken-focused, light oil
exploration and production company. 


Petrobank will capitalize PetroBakken with its CBU assets and $400 million of
cash. PetroBakken will then acquire all the outstanding shares of TriStar. In
return, Petrobank will receive 109.8 million shares of PetroBakken which will
represent approximately 64% of PetroBakken's anticipated shares outstanding. 


The transaction will be completed by way of plan of arrangement (the
"Arrangement") and is subject to TriStar shareholder approval. The information
circular for the Arrangement is expected to be mailed to TriStar shareholders on
or about August 31, 2009 and it is anticipated that the special meeting of
TriStar's shareholders will be held on or about September 30, 2009, with closing
of the transaction to occur on or about October 1, 2009. The successful
completion of the transaction is also subject to customary regulatory, stock
exchange, court and other approvals. 


PetroBakken will target significant production and reserves growth through an
internally-funded capital program underpinned by strong cash flows which will
also allow us to provide an attractive dividend yield to our shareholders. Based
on the proposed dividend policy, PetroBakken shares are expected to yield
approximately 3% based on a $0.96 annualized dividend and anticipated trading
levels for PetroBakken. 


Key Attributes of PetroBakken

PetroBakken will combine significant, high growth, long-life Bakken reserves and
production with legacy conventional light oil assets, which provide high
netbacks and a low production decline profile. PetroBakken will be the premier
Bakken player in Canada with a greater proportion of its production coming from
the Bakken than any other material producer, and will represent a compelling new
investment opportunity for investors. In addition, PetroBakken will have
significant future development opportunities in the Horn River and Montney gas
resource plays in northeast BC that will add long-term growth to PetroBakken's
attractive light oil position. After planned Alberta asset dispositions of
approximately 9,500 boepd, PetroBakken will have the following key attributes: 


- 2009 exit production is expected to be above 37,000 boepd (greater than 95%
light oil).


- More than 27,000 boepd from the Bakken (greater than 70% of total exit 2009
production).


- More than 127 mmboe of high quality, primarily light oil, proved plus probable
reserves with significant future reserve growth potential through revisions,
additions, improved recoveries and the application of new technology.


- Proved plus probable reserve life index of more than 9 years.

- Significant land inventory of over 1.0 million net acres with more than
800,000 net acres in southeast Saskatchewan, making PetroBakken the single
largest landholder in this region. Of this, over 280,000 net acres (440 net
sections) are located in the Bakken play fairway with significant additional
exposure to further Bakken exploration activity, including 80,000 net acres in
Montana.


- Incremental reserve enhancement capabilities on 110 net sections of existing
producing Bakken acreage.


- More than 1,300 future Bakken drilling locations using predominantly
long-reach, bilateral horizontal wells.


- Significant upside gas potential in the Horn River and Montney plays in
northeast BC, with more than 63,000 net undeveloped acres and over 400 potential
drilling locations, providing an additional long-term growth platform.


- Industry leading operating netbacks estimated to be above $57.00/boe based on
US$75.00 WTI.


- Expected operating costs of approximately $8.00/boe.

- Approximately $1.9 billion of tax pools.

- Run-rate cash flow of more than $700 million based on US$75 WTI oil price and
2009 exit production.


- 2010 capital budget of approximately $550 million based on a US$75 WTI oil price.

- Initial dividend of $0.96 per share per annum, payable monthly, representing a
payout ratio of 23% based on run rate cash flow.


- Excellent financial flexibility with a pro forma debt to cash flow ratio of
less than one times.


- 172 million PetroBakken shares outstanding.

- Industry leading technical team.

Strategic Rationale

The combination of the Petrobank and TriStar assets is highly complementary as
it creates a pure play investment opportunity for exposure to high-netback light
oil and the continuing technical enhancements of the Bakken resource play. In
the Bakken alone, the combined asset base creates a dominant, operationally
complementary land position providing significant long-term development growth
through the future drilling of 1,300+ identified locations.


The combined entity is expected to have an improved cost of capital as a result
of the focused nature of the high netback light oil assets in southeast
Saskatchewan.


Additionally, the strategic merger results in the combination of premier
technical teams focused on unlocking the value embedded in this large resource
base. Independently, TriStar and Petrobank have been industry leaders in
applying new, leading-edge technologies to unlock the true potential of the
Bakken resource play. Bringing these two teams together creates the preeminent
Bakken development team, utilizing best practices to continually enhance and
ultimately maximize recovery factors.


It is expected that PetroBakken's increased scale will provide superior
operating efficiencies through complementary gathering systems, oil processing
facilities, marketing arrangements and gas plant synergies.


PETROBANK FOLLOWING THE COMPLETION OF THE PETROBAKKEN TRANSACTION

Petrobank will capitalize PetroBakken with $400 million, contribute all the
Company's CBU assets and transfer all bank debt and working capital associated
with the CBU. Net Canadian bank debt at June 30, 2009 totalled $364 million and
is expected to increase to approximately $400 million by September 30, 2009 due
to increasing third quarter activity levels and land acquisitions. After closing
the PetroBakken transaction, Petrobank will have estimated cash, net of working
capital balances, of approximately $40 million, an undrawn operating line of
credit estimated to initially be $20 million and Petrobank will be receiving
over $105 million of dividends per year from PetroBakken, which together will be
used to fund ongoing Heavy Oil Business Unit expenditures and obligations
outstanding under Petrobank convertible bonds (principal amount US$405.1
million).


Following the arrangement, an investment in one share of Petrobank (basic) will
effectively represent 1.19 shares of PetroBakken, 0.71 shares of Petrominerales,
and 100% of the Heavy Oil Business Unit assets, including our proprietary
THAI(TM) and CAPRI(TM) technologies.


CANADIAN BUSINESS UNIT ("CBU") OPERATIONAL UPDATE

(all comparisons are to the second quarter of 2008)

- CBU production increased 18.5% to 19,579 boepd. 

- CBU production expenses decreased by 27% to $6.52/boe. 

- CBU operating netbacks were $42.72/boe, excluding hedging gains of $3.46/boe.

- We completed the first 20 stage fracture stimulation in Canada, using Packers
Plus technology.


- Our new drilling and completion strategy for the Bakken play now focuses on
dual leg horizontal wells with high intensity fracture stimulation, creating the
most cost effective approach to increase Bakken production and reserves.


- On August 4th, 2009, Petrobank entered into a definitive agreement with
TriStar to create PetroBakken.


Our aggressive drilling program through 2008 was followed by a dramatic slowdown
in activity during the first half of 2009 in response to significantly lower
commodity prices and field activity was further reduced during the second
quarter due to spring break up. Our 2009 drilling program resulted in only 11
(7.3 net) wells being drilled in the second quarter and 32 (24.4 net) wells
drilled in total during the first half of 2009. Production averaged 19,579
boepd, a 19% increase from the 16,517 boepd produced in the second quarter of
2008. Due to lower activity levels and field restrictions due to spring
break-up, production was down 11% from the first quarter of 2009. We anticipate
a return to strong production growth through the balance of the year as we
dramatically increase our drilling activity in the Bakken. Through most of the
first half of the year we operated with a maximum of only two rigs on the Bakken
play. We now have five rigs operating and a sixth rig will be starting shortly.
Outside of the Bakken, our activities are targeted toward building on our
expertise and drilling inventory in other large resource accumulations,
including the Montney and Horn River Basin. 


The reduced drilling pace in early 2009 provided the opportunity to re-evaluate
our Bakken drilling and completion strategies and to pioneer new techniques to
maximize returns on our Bakken program. Our new strategy of drilling long-reach,
bilateral horizontal wells provides improved production and reserves per-well by
implementing the most cost effective approach for increasing the intensity of
fracture stimulations along the length of the horizontal well bore while
reducing the inter-well distance of the horizontal well bores, sub-surface.
Furthermore, this new approach has immediate applications in our large inventory
of existing producing wells, as we can re-enter these wells and add a second
parallel horizontal leg with high intensity fracture stimulations
("re-entries"). 


TriStar's complementary inventory of undeveloped lands, and existing producers,
further increases the growth potential of PetroBakken.


Through the last half of 2009, our primary focus will be to increase Bakken
drilling activity and continue to demonstrate our ability to maintain our
low-cost advantage in developing this large resource base. We are positioned for
continued long-term reserve and production growth as we increase our pace of
development through the rest of the year. With current commodity prices we would
expect to drill a further 70 wells in addition to another 20 re-entries through
the balance of 2009, before taking into account the PetroBakken transaction. 


The Bakken Resource

Petrobank pioneered the horizontal fracture stimulation techniques that opened
up the true potential of this substantial resource, and we continue to find new
ways to improve well performance and expected ultimate recoveries from the
Bakken. This zone is a marginal reservoir that has been tested and analyzed for
more than 50 years, yet only recently have advances in technology created the
opportunity to produce significant oil from the Bakken. Recent, repeated testing
has allowed us to conclude that every time we increase the number of fracture
stimulations in a given section of land, we increase productivity and expected
ultimate recoveries from the zone.


Our efforts through early 2009 to further improve Bakken production have focused
on increasing the intensity of fracture stimulation completions (fracs) by 38%
in our long (1,400 metre) horizontals, by 200% in our short (700 metre)
horizontals, and then by 400% in our short bilateral (two 700 metre horizontal
legs from a single vertical well bore) horizontal wells. Recently, Petrobank
also completed the first 20-stage fracture stimulation in Canada using Packers
Plus technology. Our first two 20-stage frac wells have materially improved
production performance compared to offset competitor wells and were initially
free-flowing at rates in excess of 400 bopd. These results further demonstrate
the potential of our strategy to cost-effectively increase fracture stimulation
intensity and ultimate recoveries from the Bakken. We continue to build on our
innovative approach to maximizing value from the Bakken resource. 


We are now implementing our new drilling and completion strategy which is to
drill long bilateral horizontal wells (two 1,400 metre horizontal legs from a
single vertical well bore) with a total of 30 fracture stimulations (15 fracture
stimulations in each horizontal leg). These are the first wells to be drilled
this way, and Petrobank has successfully executed all the unique elements of
this approach in other wells. By combining our two most highly effective
solutions for maximizing productivity and expected ultimate recoveries, we have
developed the most capital efficient oil recovery method for the Bakken,
to-date.


We are also applying this approach to our large inventory of existing well
bores. We have started to re-enter these horizontal wells and drill second
parallel horizontal legs from the same vertical well, and complete them with
higher intensity multi-stage fracs. Initial re-entry results have resulted in
production increases of 80 to 150 bopd from previous well production rates prior
to the re-entries.


Another part of our strategy is to operate centralized facilities that capture
additional value from the gas and natural gas liquids associated with our Bakken
light oil, and to ensure field efficiencies that maintain low operating costs.
To strengthen our infrastructure, three new facilities at Viewfield, Creelman,
and Freestone were connected to our main Midale plant through 100 kilometres of
new pipelines through 2008. The future growth of our infrastructure will be
timed to match our need with future drilling. PetroBakken's combined
infrastructure will provide additional oil handling capabilities for Petrobank's
current and future locations north of our Freestone facility as well as gas
processing capabilities for TriStar wells and facilities. 


Ongoing field efficiencies have resulted in a reduction of our Bakken production
costs to $5.75/boe. This brings the average second quarter production costs for
all of our CBU operations down to $6.52/boe, a 4% decrease from the $6.81/boe
recorded in the first quarter of 2009 and a remarkable 27% reduction from the
second quarter of 2008. 


Including the TriStar assets, PetroBakken will have 330 net undeveloped Bakken
sections with a drilling inventory of over 1,300 bilateral wells, only 407 of
which have been assigned 2P reserves. This substantial drilling inventory
combined with our innovative approach to drilling and completing Bakken wells
are expected to contribute to a multi-year growth profile for PetroBakken.


Beyond Bakken

Additional long-term growth will come from Petrobank's large land position in
the Montney and Horn River natural gas resource plays located in northeast
British Columbia. The company has 17 sections of land (100% working interest) in
the Monias area with Montney potential and a further 97 (84 net) sections north
of Fort Nelson in the Horn River basin. Petrobank has, to-date, successfully
operated over 270 horizontal wells with multi-stage fracture stimulations, more
than any other operator in Canada. This experience positions Petrobank to be a
leader in the development of these massive unconventional resource plays. 


At Monias, our first Montney horizontal well was drilled in the fourth quarter
of 2008 adjacent to our 5.0 mmcfpd gas plant. Based on that successful result, a
second well is currently drilling. This well is a multi-leg horizontal with high
density fracture stimulation designed to further increase production rates and
expected ultimate gas recoveries. Our first horizontal well gas well in the Horn
River Basin was drilled in the first quarter of 2009 in an area that offers
multi-season access due to our proximity to the Alaska Highway. Based on that
successful result, a second well is planned for later this year, building on
what we learned from the first well as well as testing additional geological
concepts. 


Our immediate operational goal for both of these prolific resource plays is to
identify optimal technology applications that lower our internal hurdle for a
gas price necessary to provide a competitive rate of return that will ultimately
allow us to initiate a major full-scale development. 


HEAVY OIL BUSINESS UNIT ("HBU") OPERATIONAL UPDATE 

- Production averaged 205 bopd of partially upgraded oil. 

- P1B was drilled as a THAI(TM) well, replacing P1. 

- P2B was drilled as the second THAI(TM)/CAPRI(TM) well, replacing P2.

- We have confirmed the CAPRI(TM) in-situ catalytic upgrading effect. 

- The Kerrobert project was approved on July 9, 2009, and drilling has commenced.

Whitesands Project

During the second quarter production averaged 205 bopd, down 43 barrels per day
compared to the previous quarter as operations were ramped down and stabilized
in preparation for drilling the P1B and P2B wells. As previously reported, P1
was shut-in on March 31, 2009 and P2 was subsequently shut-in on July 24, 2009
to facilitate the drilling of the replacement wells for P1 and P2. Concurrent
with the preparation for drilling the new wells, P3B air injection was reduced
and production was stabilized at 100 bopd per day prior to and during the
drilling and completion operations. 


We commenced drilling P1B on July 5, 2009 and we completed drilling on July 16,
2009. This well is completed as a THAI(TM) well with a FacsRite(TM) liner
utilizing cartridge screens designed for superior downhole sand control, liner
integrity and increased flow area. The FacsRite(TM) liner is manufactured by
Absolute Completion Technologies in Alberta and internationally distributed by
Schlumberger. This liner configuration has been used in projects worldwide but
P1B is the first well in North America to be completed with the FacsRite(TM)
design. 


P2B is our second THAI(TM)/CAPRI(TM) well and drilling was completed on August
7, 2009. P2B has the same liner design as our successful P3B well. Both wells
are expected to be completed, tied in and operational by the end of August, with
production expected near the end of the third quarter.


P3B wellbore temperatures have been operating between 400 and 500 degrees
Celsius, well within the CAPRI(TM) catalyst range. Produced light hydrocarbons
from the P3B secondary separator averaged 36 degrees API and the combined P3B
THAI(TM)/CAPRI(TM) production from the primary and secondary separators ranged
from 12 to 15 degrees API, compared to a reservoir quality of 8 degrees API. The
CAPRI(TM) upgrading effect has been measured at as much as 3 degrees API higher
than THAI(TM) production, confirming a direct in-situ upgrading effect of the
catalyst. 


In the second quarter, we commenced a routine regulatory inspection of the
surface facilities starting with the P1 production train. During the current
drilling and completion operations, we will be able to complete the majority of
the inspections prior to resuming full operations on all three wells. To-date,
the facilities inspections have shown no evidence of any corrosion in the
vessels and associated equipment. 


Whitesands is now configured as a modified three well THAI(TM)/CAPRI(TM)
demonstration site, which will allow us to continue to test new technology
enhancements, such as oxygen enrichment, CO2 co-injection, and partial surface
upgrading. 


Kerrobert Project

Regulatory applications for the Kerrobert Project were filed on April 22, 2009
and approval was received on July 9, 2009. In our environmental application we
completed additional work to enable expansion of the project which resulted in a
slightly longer initial regulatory process but will facilitate a shorter time
frame for expansion projects. Drilling operations began on July 18, 2009 and the
first production well KP1 completed drilling on August 5, 2009. KP2 commenced
drilling on August 7, 2009 and drilling is expected to be completed next week.
Both of these wells will utilize FacsRite(TM) liners. The air injection wells
are planned to be completed by the end of August, and the pre-ignition heating
cycle (PIHC) will be initiated simultaneously. Air injection is planned to begin
in early October and first production is expected to occur at about the same
time. This two well project applies the THAI(TM) technology in a conventional
heavy oil reservoir at Kerrobert and is a 50/50 joint venture with Baytex Energy
Trust, who purchased True Energy Trust's Saskatchewan assets. With the approval
of the Kerrobert project, Petrobank earned a 50% percent interest in an initial
four sections of land. 


This joint project will highlight the applicability of the THAI(TM) technology
in Saskatchewan's conventional heavy oil resource base. We consider that a
significant portion of the estimated 20 billion of barrels of unrecovered
conventional heavy oil resources in Saskatchewan can be commercialized using
THAI(TM). In addition, Saskatchewan is actively encouraging oil and gas
development and the application of advanced technologies through government
royalty incentive programs.


May River Project 

The May River Project is our first large-scale commercial THAI(TM) application
on Petrobank's oil sands leases west of Conklin, Alberta. The May River design
builds on the experience gained from Whitesands. The project will be built in
phases, with initial production capacity of 10,000 barrels of THAI(TM) oil per
day, and an ultimate capacity of up to 100,000 bopd.


The regulatory application for May River's first phase was filed with the Energy
Resources Conservation Board and Alberta Environment in December 2008. The
application has been deemed complete by the regulatory authorities and is now
moving through the regulatory process. We expect to receive approval for the
project near the end of the year.


Front end engineering and design for the project began in the fourth quarter of
2008, and we expect to have completed this phase of engineering in the fourth
quarter of 2009. The design incorporates self-sufficient power generation
utilizing low-BTU produced gas, produced gas sweetening, simplified CO2 capture
add-on capability, and the project will be a net water producer rather than a
water user. These design elements contribute to making the May River Project a
leading environmentally sustainable process for oil sands and heavy oil
development. The project is also designed to utilize a modular approach with
direct and immediate applicability to heavy oil projects world-wide.


Dawson Project

The Dawson Project is a joint project involving our first Alberta-based, third
party THAI(TM) license. Our partner is now Shell Canada Limited, who acquired
Duvernay Oil Corp. in August 2008. The project is located near Peace River,
Alberta and will be developed in the Bluesky formation. In August 2008, a
stratigraphic well was drilled on the project site, which will be used as a
thermal observation well during the project's operating phase. The regulatory
application for the project was filed on April 2, 2009 and we expect to receive
approval by the end of 2009. This project will be virtually the same as the
Kerrobert Project and will demonstrate the THAI(TM) technology in a more mobile
oil sands reservoir.


Business Development

Our wholly-owned subsidiary, Archon Technologies Ltd., continues to evaluate a
number of innovative engineering, environmental, and other value-added
technology options to improve operational efficiency, increase production
efficiencies, and reduce the overall environmental impact of bitumen and heavy
oil recovery. The utilization of the FacsRite(TM) liner is another example of
our ability to evaluate new technologies and rapidly deploy them in the field.
Additional technologies being assessed include; elemental sulphur recovery,
enriched oxygen injection, carbon dioxide co-injection, power generation using
produced lean gas, enhanced produced water quality, and incremental surface
upgrading.


We have been in active discussions and negotiations on potential licensing
arrangements opportunities and there is a great deal of interest in our
technologies because of their superior economic and environmental benefits. Our
business strategy is to license and apply THAI(TM) and related technologies in a
wide range of large global resource opportunities.

Non-GAAP Measures. This press release contains financial terms that are not
considered measures under Canadian generally accepted accounting principles
("GAAP"), such as funds flow from operations, funds flow per share, net debt 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 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. Net debt includes bank debt plus accounts payable and accrued
liabilities less current assets (excluding future income tax asset) and is used
to evaluate the Company's financial leverage. Profitability relative to
commodity prices per unit of production is demonstrated by an operating netback.
Funds flow from operations, funds flow per share, net debt and operating
netbacks may not be comparable to those reported by other companies nor should
they be viewed as an alternative to cash flow from operations, net income or
other measures of financial performance calculated in accordance with GAAP. The
following table shows the reconciliation of funds flow from operations to cash
flow from operating activities for the periods noted:




                       Three months ended June 30, Six months ended June 30,

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 subclassified 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.


Barrels of Oil Equivalent ("boe"). Disclosure provided in this press release in
respect of boe units may be misleading, particularly if used in isolation. A boe
conversion relationship of 6 mcf to 1 bbl is based on an energy equivalency
conversion method primarily applicable at the burner tip and does not represent
a value equivalency at the well head.
