The Registrant has a separately-designated standing audit committee established in accordance with Section 3(a)(58)(A) of the Exchange Act. The members of the audit committee are: Thomas A. Cumming,
James D. McFarland, Michael S. Parrett and A. Terence Poole.

AUDIT COMMITTEE FINANCIAL EXPERT

The board of directors of the Registrant has determined that each of Michael S. Parrett and A. Terence Poole, members of the Registrants audit
committee, qualify as audit committee financial experts for purposes of paragraph (8) of General Instruction B to Form 40-F. The board of directors has further determined that each of Mr. Parrett and Mr. Poole is also independent, as
that term is defined in the Corporate Governance Listing Standards of the New York Stock Exchange. The Commission has indicated that the designation of each of Mr. Parrett and Mr. Poole as an audit committee financial expert does not make
either of them an expert for any purpose, impose any duties, obligations or liabilities on them that are greater than those imposed on members of the audit committee and the board of directors who do not carry this designation or affect
the duties, obligations or liabilities of any other member of the audit committee or the board of directors.

Disclosure provided
herein in respect of a BOE and an McfGE may be misleading, particularly if used in isolation. A BOE conversation ratio of six (6) Mcf of natural gas to one barrel of oil and an McfGE conversion ratio of one barrel of oil to six (6) Mcf of
natural gas is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. In addition, given that the value ratio based on the current price of crude oil as
compared to natural gas is significantly different from the energy equivalent of 6:1, utilizing a conversion on a 6:1 basis may be misleading as an indication of value.

PRESENTATION OF OUR FINANCIAL INFORMATION

Financial information in this Annual Information Form has been prepared in accordance with International Financial Reporting Standards
(IFRS). IFRS differs in some significant respects from United States generally accepted accounting principles (US GAAP) and thus our financial statements may not be comparable to the financial statements of
companies following US GAAP.

Unless otherwise stated, all sums of money referred to in this Annual Information Form are expressed in Canadian
dollars.

PRESENTATION OF OUR RESERVE INFORMATION

National Instrument 51-101 Standards of Disclosure for Oil and Gas Activities(NI 51-101) of the Canadian Securities
Administrators permits oil and gas issuers, in their filings with Canadian securities regulators, to disclose not only Proved Reserves but also Probable Reserves, Possible Reserves and Contingent Resources, and to disclose reserves and production on
a gross basis before deducting royalties. Probable Reserves and Possible Reserves are of a higher risk and are less likely to be accurately estimated or recovered than Proved Reserves. Contingent Resources are higher risk than Probable Reserves and
Possible Reserves and are less likely to be accurately estimated or recovered than Probable Reserves or Possible Reserves. Because we are permitted to prepare this Annual Information Form in accordance with Canadian disclosure requirements, we have
disclosed in this Annual Information Form resources designated as Probable Reserves, Possible Reserves and Contingent Resources and have disclosed reserves and production on a gross basis before deducting royalties.

Current SEC reporting requirements permit oil and gas companies to disclose Probable Reserves and Possible Reserves, in addition to the required
disclosure of Proved Reserves. If this Annual Information Form was required to be prepared in accordance with US disclosure requirements, the SECs requirements would prohibit Contingent Resources from being disclosed. Under current SEC
requirements, net quantities of reserves are required to be disclosed, which requires disclosure on an after royalties basis and does not include reserves relating to the interests of others. For a description of these and additional differences
between Canadian and US standards of reporting reserves, see Risk Factors  Canadian and United States practices differ in reporting reserves and production and our estimates may not be comparable to those of companies in the
United States. Additional information prepared in accordance with the US Financial Accounting Standards Boards Accounting Standards Update (Extractive Activities-Oil and Gas (Topic 932)) relating to our oil and gas reserves is
set forth in our current Form 40-F, which is available through EDGAR at the SECs website at www.sec.gov.

FORWARD-LOOKING STATEMENTS

This Annual Information Form contains forward-looking statements within the meaning of securities laws, including the safe harbour provisions of Canadian securities legislation and the
United States Private Securities Litigation Reform Act of 1995. Forward-looking information is often, but not always, identified by the use of words such as anticipate, believe, expect,
plan, intend, forecast, target, project, guidance, may, will, should, could, estimate, predict or similar
words suggesting future outcomes or language suggesting an outlook. Forward-looking statements in this Annual Information Form include, but are not limited to: benefits and synergies resulting from our corporate and asset acquisitions, business
strategy and strengths, goals, focus and the effects thereof, acquisition criteria, capital expenditures, reserves, resources, reserve life indices, estimated production, production additions from our 2013 development program, dispositions and
rationalization plans, remaining producing reserves lives, operating expenses, asset retirement obligations, royalty rates, net present values of Future Net Revenue from reserves, commodity prices and costs, dividend policy, exchange rates, the
impact of contracts for commodities, development plans and programs, future development costs and the funding thereof, tax horizon, future income taxes, the impact of proposed changes to Canadian tax legislation or US tax legislation, abandonment
and reclamation costs, government royalty rates (including estimated increase in royalties paid and estimated decline in net present value of reserves and 2013 cash flows) and expiring acreage. Statements relating to reserves and resources are
forward-looking statements, as they involve the implied assessment, based on certain estimates and assumptions that the reserves and resources described exist in the quantities predicted or estimated and can profitably be produced in the future.

Forward-looking statements and information are based on our current beliefs as well as assumptions made by, and information currently
available to, us concerning anticipated financial performance, business prospects, strategies, regulatory developments, future oil and natural gas commodity prices and differentials between light, medium and heavy oil prices, future oil and natural
gas production levels, future exchange rates, the proceeds of anticipated divestitures, the amount of future cash dividends paid by the Corporation, the cost of expanding our property holdings, our ability to obtain equipment in a timely manner to
carry out development activities, our ability to market our oil and gas successfully to current and new customers, the impact of increasing competition, our ability to obtain financing on acceptable terms, and our ability to add production and
reserves through our acquisition, development and exploration activities. Although management considers these assumptions to be reasonable based on information currently available to it, they may prove to be incorrect.

By their very nature, forward-looking statements involve inherent risks and uncertainties, both general and specific, and risks that predictions,
forecasts, projections and other forward-looking statements will not be achieved. We caution readers not to place undue reliance on these statements as a number of important factors could cause the actual results to differ materially from the
beliefs, plans,

On May 11, 2010, Pengrowth Corporation issued the 2010 Senior Notes. The notes were issued in
two series; US$71.5 million of 4.67 percent notes due in 2015 and US$115.5 million of 5.98 percent notes due in 2020.

On January 14,
2010, certain outstanding debentures were redeemed at a cash redemption price of $1,025 per $1,000 principal value for a total cost of $76,609,525, plus accrued and unpaid interest to the redemption date. The cash redemption amount was funded with
incremental borrowings from the Credit Facility.

DESCRIPTION OF OUR BUSINESS

General

We
are engaged in the development, production and acquisition of, and the exploration for, oil and natural gas reserves in the provinces of Alberta, British Columbia, Saskatchewan, Ontario and Nova Scotia. Our long term goal is to maximize value
creation for the benefit of our Shareholders. Our competitive position is dependent on our ability to execute our business strategy. We believe we have the skills and financial capacity to develop our opportunities. A key factor affecting our
finances is commodity prices over which we have no control.

As at December 31, 2012, we had 641 permanent employees.

Business Strategy

Our corporate strategy is to use funds flow from our existing conventional operations to sustain our current dividend and to fund a portfolio of oil assets with low declines and long reserve lives aimed
at supporting production growth and long-term stable dividend payout. Our plan is to rationalize our asset base over the coming year and to dispose of up to $700 million of non-core assets (in addition to the disposition of our Weyburn interest
which is expected to be sold in early March 2013 for gross proceeds of $315 million).

Our operational expertise is in the WCSB. We rely on
our expertise to partially offset production declines in our mature oil and gas properties as well as develop new production in less mature oil and gas properties. We continue to develop our significant expertise in horizontal well multi-stage
fracturing technology, EOR technologies and waterflood optimization. Additionally, we have assembled a highly skilled team experienced in thermal development. Our inventory of undeveloped land and opportunities on our properties provide future
drilling opportunities for the short-term and mid-term. In the mid-term, we anticipate continuing to develop our thermal project at Lindbergh, with the potential for a 50,000 bbl/d of bitumen commercial project as well as our light oil and
liquids-rich gas properties at Swan Hills and in the Greater Olds/Garrington area. See additional details on these properties under Operational Information  Principal Producing Properties below.

For 2013, we have established a $770 million capital spending level that retains significant flexibility in an uncertain commodity price environment.
Included in this budget is $300 million for expenditures related to the first commercial phase of our Lindbergh project which is anticipated to produce 12,500 bbl/d of bitumen commencing in early 2015. We prioritize our capital investments
based on:



| |  |  | recycle ratio;
| | - |  | --------------



| |  |  | net present value of future cash flow as compared to the capital invested;
| | - |  | --------------------------------------------------------------------------



| |  |  | rate of return of future cash flows;
| | - |  | ------------------------------------



| |  |  | potential for continued, repeatable and scalable development; and
| | - |  | -----------------------------------------------------------------



| |  |  | investments necessary to maintain existing facilities and wells.

Lindbergh

The Lindbergh
property is located approximately 420 kilometres northeast of Calgary and 50 kilometres south of Bonnyville. We have a 100% Working Interest in the Lindbergh oil sands leases, located in the Cold Lake oil sands district in north-eastern Alberta and
covering 27,200 net acres (42.5 sections). Our Lindbergh thermal project includes our Muriel Lake lands which are about eight kilometers to the northeast of the Lindbergh lease.

We began steam injection into the pilot project in early February 2012 and results outperformed expectations during the year. The pilot, which consists of two well pairs, has been producing for over 10
months and is currently producing in excess of 1,600 bbl/d of bitumen, with an ISOR of 1.7. The well pairs had each produced approximately 163,000 bbls of bitumen as of December 31, 2012.

The excellent pilot results and associated reserve potential have provided us with the confidence needed to accelerate and expand the first phase
of commercial development. On January 10, 2013, our Board of Directors approved the first phase of Lindbergh commercial development, which is expected to reach 12,500 bbl/d of bitumen by early 2015. Two additional expansion phases are expected
to increase total Lindbergh production to 50,000 bbl/d of bitumen by 2018.

Swan Hills Area

We have varied Working Interests within the Swan Hills area in all of the key properties throughout this significant regional resource base. These are both operated and non-operated, unit and non-unit
properties in Judy Creek, Carson Creek, House Mountain, Deer Mountain, Swan Hills, South Swan Hills, Virginia Hills and Freeman. The properties are primarily located approximately 160  240 kilometres northwest of Edmonton, Alberta.

The two major operated properties in the area are:



| |  |  | The Judy Creek Beaverhill Lake Unit and the Judy Creek West Beaverhill Lake Unit are both oil properties (together referred to as Judy
Creek), where we have a 100 percent Working Interest in both. Judy Creek covers an area of approximately 38,300 acres, was discovered in 1959, placed on waterflood in 1962 and hydrocarbon miscible flood in 1985. We also have a 54.4 percent
Working Interest in and operate the Judy Creek Gas Conservation Plant that services a number of other properties in the area including Swan Hills, Virginia Hills and South Swan Hills.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Carson Creek is comprised of two Pengrowth operated units (one oil and one natural gas) covering approximately 46,200 acres. The Carson Creek North
Beaverhill Lake Unit No. 1, in which we have an 89.1 percent Working Interest, was discovered in 1958 and the current waterflood was initiated in 1964. The Carson Creek Beaverhill Lake Unit No. 1, in which we have a 95.1 percent Working
Interest, was discovered in 1958.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In 2012, $171 million (net) was spent on light oil and liquids-rich gas plays in this
area. In addition to ongoing miscible flood development and waterflood optimization, we drilled a total of 24 operated horizontal wells (22.7 net) at Judy Creek, Deer Mountain, Virginia Hills and Carson Creek, primarily in the tighter platform and
R5 shoal. Multi-stage fracture treatments were used in the completion of these wells. Drilling also occurred in the partner-operated properties where we participated in 9 oil wells (1.6 net) at House Mountain and Freeman.

After very high levels of drilling activity in the area over the past several years, we will now shift to a more balanced mix of drilling, waterflood,
miscible flood, and well optimization (re-entries, recompletions, workovers) across the properties.

Greater Olds/Garrington Area

Our Olds property is located 95 kilometres north of Calgary, Alberta. Our interests in this area include a 100
percent ownership in the Olds Gas Field Unit No. 1. In addition, we have a 74 percent average Working Interest in the adjacent non-unit reserves. The Olds unit produces sour natural gas from the Wabamun Formation, with H2S concentrations ranging from less than one percent to 35 percent. The
non-unit reserves are contained within formations from the Wabamun to the Edmonton group, and are predominantly sweet natural gas.

We operate
and own 100 percent of the sour gas processing plant at Olds, which processes both our production and third party volumes. Third party volumes represent approximately 35 percent of the total volumes processed.

The Harmattan gas field, within the Olds area, is located approximately 90 kilometres northwest of Calgary, Alberta. It is comprised of wells and pools
in formations from the Cardium to the Wabumun, as well as two partner-operated Elkton units. The production is predominantly sweet liquids-rich natural gas and sweet oil with Working Interests averaging 65 percent in the non-unit lands (operated)
and 25 percent in the partner-operated units.

The Olds area is characterized by stacked reservoirs with multi-zone potential. Pengrowth has
been exploiting several development opportunities over the past two years in Harmattan, including the development of our liquids-rich (50 bbls/MMcf) Elkton gas play and more recently, the liquids-rich (90 bbls/MMcf) Mannville gas play.

On May 31, 2012, Pengrowth acquired 149.5 net sections of land with multi-zone potential in the Cochrane to Sylvan Lake corridor pursuant to the NAL
Acquisition. The primary target on these lands is the Cardium formation which produces light oil and Pengrowth estimates that there are more than 195 net drilling locations on these lands. Other zones of interest include the liquids-rich Mannville
and Elkton formations.

In 2012, we spent $95 million in the Olds/Garrington area on activities targeting the Elkton, Mannville and Cardium
plays, drilling 35 gross wells (17.8 net) during the year.

Southeast Saskatchewan

Our southeast Saskatchewan area is located 200 kilometres southeast of Regina, Saskatchewan. Our interests include primarily
50 percent ownership in various non-operated fields which include Alida, Nottingham, Rosebank, Star Valley, Midale, Elswick, Steelman and Hoffer. Pengrowth also has 100 percent ownership in the operated Willmar field. The southeast Saskatchewan
area produces sour medium/light oil (28° to 40° API) primarily from the Mississippian formations (Frobisher, Midale, Ratcliffe, and Oungre zones) with H2S concentrations ranging from 1.5 percent to 8 percent. Solution gas is conserved in most fields.

Although Mississippian production is considered to be relatively mature, there are plans for further infill drilling in the Frobisher, Midale and Oungre
zones and waterflood optimization potential in the Midale zone in various fields.

Approximately $19 million of capital has been allocated to
the southeast Saskatchewan area in 2013 to drill up to 21 wells (13 net) targeting the Mississippian formations.

The
Weyburn Unit is located in southeastern Saskatchewan. At December 31, 2012, we held a 10.01952 percent Working Interest in this unit which is operated by a senior producer. We expect to dispose of our interest in Weyburn in early March 2013
with an effective date of January 1, 2013. The unit produces medium sour crude oil (25° to 34° API) from the Midale carbonate reservoir under waterflood and CO2EOR miscible flood. The field consists of approximately 600 production wells and 330 injection wells currently producing
approximately 2,500 BOE/d (net) to Pengrowth. The reserves data below includes reserves attributed to Weyburn.

Statement of Oil and Gas Reserves and Reserves Data

Disclosure of Reserves Data

The information in this section is based upon an
evaluation by GLJ, prepared in accordance with NI 51-101, with an effective date of December 31, 2012 contained in the GLJ Report, with the exception of information relating to income tax and the after tax Future Net Revenues
associated with our reserves, which we determined. The effective date of the information in this section is December 31, 2012 and the preparation date is January 18, 2013 when the final information was provided. The information
in this section summarizes our oil, liquids and natural gas reserves and the net present values of Future Net Revenue for these reserves using GLJs forecast prices and costs and constant prices and costs. We engaged GLJ to provide an
independent evaluation of Proved Reserves and Proved Plus Probable Reserves and no attempt was made to evaluate Possible Reserves in our conventional properties. It is our practice to obtain an engineering report evaluating all of our Proved
Reserves and Probable Reserves as at December 31 of each year. Only in respect of the Lindbergh oil sands property and the Groundbirch natural gas property did GLJ evaluate Possible Reserves and Contingent Resources. All of our reserves are in
Canada in the provinces of Alberta, British Columbia, Saskatchewan, Ontario and Nova Scotia. In certain instances in this Annual Information Form, we have presented estimates of reserves, Future Net Revenue and Contingent Resources for individual
properties. The estimates of reserves, Future Net Revenue and Contingent Resources for individual properties may not reflect the same confidence level as estimates of reserves, Future Net Revenue and Contingent Resources for all properties, due to
the effects of aggregation.

The following tables set forth certain information relating to our oil and natural gas reserves and the net
present value of the estimated Future Net Revenue associated with such reserves as at December 31, 2012 contained in the GLJ Report. These tables summarize the data contained in the GLJ Report, and, as a result, may contain slightly
different numbers than the GLJ Report due to rounding. Columns may not add due to rounding.

Our Future Net Revenues associated with the
production and reserves contained in this Annual Information Form reflect the royalty programs in-place on December 31, 2012.

The information set forth below is derived from the GLJ Report, which has been prepared in accordance with the standards contained in the Canadian
Oil and Gas Evaluation (COGE) Handbook and the reserves definitions contained in NI 51-101 and the COGE Handbook. The GLJ Report incorporates estimates of future well abandonment obligations but does not include estimates of
remediation costs. The GLJ forecasts of Future Net Revenue are stated prior to any provision for income taxes, interest costs or general and administrative costs and after the deduction of estimated future capital expenditures for wells to which
reserves have been assigned. The estimated Future Net Revenue shown below does not represent the fair market value of the properties. There is no assurance that such price and cost assumptions will be attained and variances could be material. The
recovery and estimates of crude oil, NGL and natural gas reserves provided herein are estimates only and there is no guarantee that the estimated reserves will be recovered. Actual crude oil, NGL and natural gas reserves may be greater than or less
than the estimates provided herein.

We determined the Future Net Revenue and present value of Future Net Revenue after income taxes by
utilizing GLJs before income tax Future Net Revenue and our estimate of income tax. Our estimate of cash income tax makes use of the following assumptions:



| |  |  | Corporate income tax at the current legislated rate;
| | - |  | ----------------------------------------------------



| |  |  | Annual general and administrative expenses at the current rate;

The after-tax net present value of our oil and gas properties reflects the tax burden of our properties on a stand-alone
basis. It does not provide an estimate of the value of us as a business entity, which may be significantly different.

The net revenues
estimated in the GLJ Report represent estimates of the revenues from oil and gas sales from our petroleum and natural gas properties together with an estimate of processing revenues less royalties (net of incentives), mineral taxes, field operating
expenses and capital obligations. These net revenues are not the same as cash flows from operating activities reported by the Corporation in our statement of cash flows. The GLJ Report does not estimate general and administrative expenses and
interest.

In accordance with the requirements of NI 51-101, the Report on Reserves Data by Independent Qualified Reserves Evaluator in
Form 51-101F2 and the Report of Management and Directors on Oil and Gas Disclosure in Form 51-101F3 are attached to this Annual Information Form as Appendices A and B, respectively.

Constant Prices used in Estimates

The constant price assumptions assume the continuance of current laws, regulations and operating costs in effect on the date of the GLJ Report. Product prices were determined from the actual prices on the
first day of each month during 2012 and were not escalated. In addition to the product prices, operating and capital costs have no inflationary increase. The constant prices are as follows:

Significant factors bearing on the reserves reconciliation were as follows:



| |  | Net reserve additions from drilling activity, improved recovery, technical revisions and change due to economic factors replaced 66 percent and 327 percent of
2012 production for Proved Reserves and Total Proved Plus Probable Reserves, respectively. Based on all changes, including acquisitions and dispositions, reserve replacement was 306 percent and 672 percent for Proved Reserves and Proved
Plus Probable Reserves, respectively.
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | An increase of 109 MMboe from acquisitions, net of minor dispositions, accounted for approximately 51 percent of the Total Proved Plus Probable Reserves added in 2012.
This was almost entirely from the NAL Acquisition, as well as some asset acquisitions primarily at Quirk Creek, Lone Pine Creek, Lochend, Weyburn Unit and Sawn Lake.
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | New reserve additions for development activity during 2012 amounted to 107 MMboe of Total Proved Plus Probable Reserves, almost all in our oil and liquids rich gas
properties. The most significant resulted from anticipated sanctioning of the phase one commercial development at our Lindbergh thermal project. Other notable additions were for drilling extensions at Tangleflags, Harmattan, Jenner and Swan Hills.
Reserve increases in the Proved Developed Producing category also resulted from the reclassification of Proved or Probable Undeveloped Reserves to producing primarily for drilling extensions and improved recovery projects at Harmattan, Weyburn,
Jenner and Judy Creek.
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Minor technical revisions due to improved performance in various properties resulted in a net increase of 4 MMboe of Total Proved Plus Probable Reserves. This was
offset by an estimated 7 MMboe negative change in Total Proved Plus Probable Reserves due to adverse economic factors associated with lower forecasted commodity prices.

Additional Information Relating to Reserves Data

Undeveloped Reserves

Undeveloped
Reserves are those reserves expected to be recovered from known accumulations where a significant expenditure is required to render them capable of production.

Proved Undeveloped Reserves and Probable Undeveloped Reserves have been estimated in accordance with procedures and standards contained in the COGE Handbook. In general, Undeveloped Reserves are scheduled
to be developed within the next two to three years. Much of the remaining capital scheduled beyond this period is for staged developments such as the Judy Creek, Swan Hills and Weyburn miscible flood projects, and the Lindbergh thermal development.
Other longer term capital expenditures are for gas development most of which has been deferred with capital being allocated instead to higher-impact oil opportunities.

Proved Undeveloped Reserves

Our
Proved Undeveloped Reserves comprise approximately 18 percent of Company Interest total Proved Reserves on a barrel of oil equivalency basis. Company Interest Proved Undeveloped Reserves of 55.5 MMboe were assigned by GLJ in accordance with
NI 51-101. In general, Proved Undeveloped Reserves were assigned to certain properties because we intend to make the needed capital commitments to convert the Undeveloped Reserves to Proved Developed Producing Reserves in the next few years.
Proved Undeveloped Reserves have been primarily assigned for future oil sands development, miscible flood expansion and development drilling.

The Lindbergh thermal project, currently under development and anticipated to come on stream in 2015, accounts for 20 percent of our Proved Undeveloped Reserves. The Groundbirch Montney gas property
amounts to approximately 11 percent of our Proved Undeveloped Reserves. Drilling is forecast by GLJ to occur over the next three years to develop these reserves. In the Judy Creek and Judy Creek West units, drilling and miscible flood development is
forecast to continue until 2017 and accounts for another nine percent of Company Interest Proved Undeveloped Reserves. Similarly, in the Swan Hills unit miscible flood expansion, as well as some infill drilling, comprises seven percent of
our Company Interest Proved Undeveloped Reserves. The Swan Hills unit reserves have a 50 year Remaining Reserve Life. The incremental recovery is reflected in the GLJ Report and miscible flood expansion is forecasted to continue until 2031. The
Cardium formation at Harmattan, Garrington and Lochend contains approximately eight percent of our Proved Undeveloped Reserves. Development drilling in these fields is forecast to occur over the next four years. In the Weyburn Unit, the Proved
Undeveloped Reserves amount to six percent of the total, and reflect the capital allocated to infill drilling, waterflood realignment and CO2miscible flood expansion, forecast to continue until 2018. As mentioned earlier, we sold our ownership in the Weyburn Unit
in a transaction which is expected to close in early March 2013. Our CBM development requires further drilling at Twining, Huxley and Fenn Big Valley. Because of the extensive land holdings and slower pace of development, this is forecast to occur
over the next five years and represents another six percent of the Proved Undeveloped Reserves.

Probable Undeveloped Reserves

Probable Undeveloped Reserves were assigned by GLJ in accordance with the requirements and standards of NI 51-101 and the COGE
Handbook. Our Probable Undeveloped Reserves amount to 143 MMboe and represent about 28 percent of the Total Proved Plus Probable Reserves. Probable Undeveloped Reserves are assigned for similar reasons and generally to the same properties as
Proved Undeveloped Reserves, but also meet the requirements of the reserve classification to which they belong. Our largest Probable Undeveloped Reserves are distributed among certain properties as a percent of the total as follows: Lindbergh (57
percent), Groundbirch (11 percent), Weyburn Unit (three percent) and Tangleflags (three percent).

We expect to fund future development costs with a combination of cash flow and proceeds from non-core asset dispositions.
There are no reserves that are expected to be limited in their recovery due to their cost of development. We have established a $770 million capital expenditure program for 2013 to fund our land acquisition, development and exploration
activities, including expenditures of $300 million at our Lindbergh thermal project.

Finding, Development and
Acquisition Costs

Finding and Development Costs

During 2012, we spent $461.0 million on development and optimization activities, which added 21.0 MMboe of Proved Reserves and 103.8 MMboe of Total Proved Plus Probable Reserves including revisions. The
development and optimization activities exclude $6.8 million in expenditures mainly for information technology projects in the Calgary office. The largest reserve additions were for drilling and improved recovery projects at Lindbergh, Tangleflags,
Harmattan and Jenner.

In total, we participated in drilling 183 gross wells (93.3 net wells) with a 97 percent success rate.

Extensive development occurred in the Pengrowth-operated Swan Hills Beaverhill Lake trend during 2012. In addition to ongoing miscible flood development
and waterflood optimization, we also drilled a total of 15 (14.8 net) horizontal oil wells at Judy Creek, primarily in the tighter platform and reef margin. In addition, we drilled two (1.9 net) liquids-rich gas wells at Carson Creek and four (2.1
net) oil wells in Deer Mountain and Virginia Hills. Multi-stage acid fracture treatments were used in the completion of these wells. We also participated in drilling eight (1.5 net) partner operated wells in the House Mountain area.

At Lindbergh, we drilled 23 (23.0 net) stratigraphic test/observation wells during 2012 to better understand the reservoir and delineate the pool. In
addition, steam facilities were completed for our SAGD pilot, which commenced injection in early February 2012, and ongoing expenditures were made in preparation for commercial development.

In the Olds area, we drilled, or participated in the drilling of, 15 (10.0 net) successful horizontal wells resulting in seven (3.0 net) Cardium oil wells and six (5.0 net) Elkton and two (2.0 net)
Mannville liquids rich gas wells.

In the lands acquired in connection with the NAL Acquisition, we drilled eight (4.4 net) horizontal Cardium
oil wells in Lochend and 12 (3.7 net) in Garrington.

Further development and optimization occurred in the CO2miscible flood and waterflood areas of the Weyburn Unit in southeast
Saskatchewan. During 2012, 23 (2.3 net) wells were drilled in the unit, consisting of 17 (1.7 net) water and CO2injection wells and six (0.6 net) oil producers.

Various other drilling programs and
optimization work were conducted during 2012 to test new concepts, increase production and maximize recoveries.

Acquisitions and
Divestitures

Pengrowth experienced a very active year in 2012 making significant strategic corporate and asset acquisitions. We spent
$1.7 billion on acquisitions adding 76.8 MMboe of Proved Reserves and 110.8 MMboe of Proved Plus Probable Reserves. We also made some minor dispositions, selling 1.0 MMboe of Proved Reserves and 1.4 MMboe of Proved Plus Probable for net proceeds of
$27 million.

On May 31, 2012 we completed the NAL Acquisition which added to our inventory of high quality light oil drilling
opportunities and increased our cash flow base which funds our development activity. This also added 96.2 MMboe of Proved Plus Probable Reserves as of the closing date. Other asset acquisitions throughout the year added another 14.6 MMboe of Proved
Plus Probable Reserves. These included Quirk Creek and Weyburn where we increased our existing ownership and Sawn Lake and Lochend which provided additional light oil drilling locations.

Future Development Capital

NI 51-101 requires that the calculation of F&D Costs include changes in forecasted future development capital (FDC) relating to the reserves. FDC reflects the amount of capital
estimated by the independent evaluator that will be required to bring non-producing, undeveloped or probable reserves on stream. These forecasts of FDC will change with time due to ongoing development activity, inflationary changes in capital costs
and acquisition or disposition of assets. We provide the calculation of FD&A Costs both with and without change in FDC. We include FD&A Costs because we believe that acquisitions and dispositions can have a significant impact on our ongoing
reserve replacement costs.

The aggregate of the exploration and development costs incurred in the most recent financial year and the change during
that year in estimated future development costs generally will not reflect total finding and development costs related to reserves additions for that year.

Recycle Ratio

We calculate the recycle ratio to measure our
performance. It reflects the amount of cash flow relative to investment and is able to be compared both internally and externally. To calculate the recycle ratio, we divide annual operating netback by annual P+P F&D Costs including change in
FDC.

Properties with No Attributed Reserves

The following table sets forth the gross and
net acres of unproved properties held by us as at December 31, 2012 and the maximum net area of unproved properties for which we expect our rights to explore, develop and exploit to expire during 2012. There are no material work
commitments necessary to maintain these properties.

When determining gross and net acreage for two or more leases covering the same lands but
different rights, the acreage is reported for each lease. Where there are multiple discontinuous rights in a single lease, the acreage is reported only once.

Bonnyville. We have a 100% Working Interest in the Lindbergh oil sands leases, located in the Cold Lake oil sands district in north-eastern Alberta and covering 20,800 net acres (32.5 sections). Our Muriel Lake property, which is included in our
Lindbergh thermal project, is about eight kilometers to the northeast of the Lindbergh lease and is comprised of an additional 6,400 net acres (10 sections). There were a total of 116 existing wells that have been used in the geological
evaluation including 10 on the Muriel Lake property. The Corporation has drilled and evaluated 59 delineation wells since acquiring the Lindbergh property in 2004. Additionally, 59 square kilometres of three dimensional seismic along with 55
kilometres of two dimensional seismic has been shot and evaluated.

The main bitumen resource at Lindbergh is located
within the Lloydminster Formation of the Mannville Group, at an approximate depth of 500 metres. Oil quality ranges from 9.5-11oAPI. The average exploitable reservoir pay thickness is 14.3 metres in the 12,500 bbl/d first phase commercial project
area. There appear to be no top water or top gas thief zones within the Lloydminster Formation in the project development area. A competent cap-rock is provided by the General Petroleum shale, which is pervasive and consistent throughout the area.

We own a central processing facility and pad site and drilled and completed two SAGD well pairs in December 2011. The wells were drilled from
a single pad with each having an effective horizontal well length of approximately 840 metres within the bitumen-bearing Lloydminster formation.

Both well pairs encountered high quality reservoir throughout with no lean zones or shale barriers in any of the well bores. Steaming operations began at the Lindbergh pilot in early February 2012. Based
on favourable pilot results, Pengrowth plans a commercial project with a first phase design capacity of 12,500 bbl/d of bitumen (including the pilot area) with an expected project life of 25 years. Over the life of the 12,500 bbl/d commercial
project, 60-65 well pairs are expected to be drilled from eight or nine well pads within the project area, recovering in excess of 107 MMbbls of bitumen. The production life for each individual well pair is expected to be 8  12 years. Under
our development plan, as individual well pair production declines, additional well pairs would be drilled throughout the Lindbergh project area to maintain production. The initial phase is expected to reach peak production by the second quarter of
2015. Future expansion of the Lindbergh commercial project, including the Muriel Lake property, is expected to increase the production capacity to 30,00050,000 bbl/d of bitumen.

The Corporation submitted an application for a 12,500 bbl/d first phase commercial project to the ERCB and Alberta Environment on December 23, 2011. Regulatory approval of this application is
expected in the second quarter of 2013, with construction to commence in the third quarter 2013.

Proved, Probable and Possible Reserves have
been assigned to the project development area. In addition, there are economic Contingent Resources for the area beyond the reserves. GLJ has updated the evaluation of the reserves and Contingent Resources for Lindbergh as of December 31, 2012.
The evaluation was limited to portions of the reservoir amenable to SAGD. The profitability of the commercial project will be sensitive to oil prices and reservoir quality. The project is forecast to be profitable using forecast prices and costs as
well as constant prices and costs.

The tables below summarize the estimated volumes of Company-Interest reserves and economic Contingent
Resources attributable to the Lindbergh property based upon forecast prices and costs. The estimates are in accordance with the definitions and guidelines in the COGE Handbook and NI 51-101. Please note that reserves and Contingent Resources
involve different risks associated with achieving commerciality. Under the fiscal conditions, including commodity price and cost assumptions, applied in the estimation of reserves, the likelihood that a project will achieve commerciality is assumed
to be 100 percent, whereas the likelihood of a Contingent Resource achieving commerciality may be less than 100 percent.

Proved, Probable and
Possible Reserves have been assigned within the region of the proposed commercial development area where the pool has been sufficiently delineated. The Proved and Probable Reserves attributed to the Lindbergh property have been included in the
reserves disclosed under Statement of Oil and Gas Reserves and Reserves Data.

Contingent Resources have been assigned to the remaining areas of the reservoir within the property that meet certain
minimum criteria. Contingent Resources are estimated on the basis of a technically feasible SAGD recovery project having been defined. However, there is no certainty that it will be commercially viable to produce any portion of the Contingent
Resources.

Best Estimate and High Estimate Contingent Resources have decreased from the previous year-end as shown below. This is due to a
significant volume now being reported as reserves resulting from further pool delineation and our commitment to develop the Phase 1 commercial project. In 2012, we drilled 18 stratigraphic test/observation wells. A significant portion of the
resource volumes are still classified as a resource rather than a reserve due to the following contingencies:



| |  |  | Higher evaluation well density  additional drilling within the area of the known accumulation is required to allow further project and reserves
definition.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Firm development plans and company commitment for future development phases  confirmation of corporate intent to proceed with defined expansion
plans within an acceptable time period.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | High quality project design and cost estimates for any phases of potential future expansion projects, needed to confirm positive project economics.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Submission of regulatory application to expand the currently proposed Phase 1 development area.
| | - |  | -----------------------------------------------------------------------------------------------

We anticipate these contingencies will be satisfied over time which should allow us to book some portion of the Contingent Resources as Proved, Probable
and Possible Reserves each year going forward.

Notes:



|(1) | 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. The contingencies may include factors such as economics, legal, environmental, political, regulatory
or lack of markets. Contingent Resources are further classified in accordance with the level of certainty associated with the estimates.

|(3) | Best Estimate is a best estimate of the quantity of oil that will be recovered from the accumulation, which under probabilistic methodology reflects a
fifty percent confidence level.

The accuracy of resource estimates is, in part, a function of the quality and quantity of
available data and of engineering and geological interpretation and judgment. The size of the resource estimate could be positively impacted, potentially in a material amount, if additional delineation wells determine that the aerial extent,
reservoir quality and/or the thickness of the reservoir is larger than what is currently estimated based on the interpretation of seismic and well control. The size of the resource estimate could be negatively impacted, potentially in a material
amount, if additional delineation wells determine that the aerial extent, reservoir quality and/or the thickness of the reservoir are less than what is currently estimated based on the interpretation of the seismic and well control.

Groundbirch Reserves and Contingent Resources

The Groundbirch property is located approximately 40 kilometres southwest of Ft. St. John, British Columbia and covers an area of approximately
13,440 acres. We have an average 90 percent Working Interest in the lands that we acquired with Monterey in September 2010.

Production
from the Montney formation began on this property in December 2010. For those areas producing and immediately adjacent, GLJ has assigned proven, probable and possible reserves. For areas outside of this, GLJ has completed a Contingent Resource
assessment.

The tables below summarize the estimated volumes of Company Interest reserves and economic Contingent Resources attributable to
the Groundbirch property based upon forecast prices and costs. The estimates are in accordance with the definitions and guidelines in the COGE Handbook and NI 51-101. Please note that reserves and Contingent Resources involve different risks
associated with achieving commerciality. Under the fiscal conditions, including commodity price and cost assumptions, applied in the estimation of reserves, the likelihood that a project will achieve commerciality is assumed to be 100 percent,
whereas the likelihood of a Contingent Resource achieving commerciality may be less than 100 percent.

Contingent Resources have been assigned to the remaining areas of the reservoir within the property that meet certain minimum criteria. GLJs
estimate of economic 2012 Contingent Resources are the same as 2011 year end as shown below. Production performance through the year was as predicted and ultimate recoveries remain unchanged when compared to the 2011 reserve report. There was no
drilling and completion activity on the lands during 2012.

Contingent Resources are assigned on the basis of a technically feasible recovery
project having been defined. These Contingent Resources are expected to be economic to develop. The Groundbirch tight gas resource is still in the early stage of evaluation and delineation in the area. The reclassification of these Contingent
Resources as reserves is contingent upon obtaining additional drilling, completion and test data which is required before Pengrowth can commit to further development. However, there is no certainty that it will be commercially viable to produce any
portion of the Contingent Resource.

The accuracy of resource estimates is, in part, a function of the quality and quantity of available data and of engineering and geological interpretation
and judgment. The size of the resource estimate could be positively impacted, potentially in a material amount, if additional development wells determine that the aerial extent, reservoir quality and/or the thickness of the reservoir is larger than
what is currently estimated based on the interpretation of seismic and well control. The size of the resource estimate could be negatively impacted, potentially in a material amount, if additional development wells determine that the aerial extent,
reservoir quality and/or the thickness of the reservoir are less than what is currently estimated based on the interpretation of the seismic and well control.

Forward Contracts

We use financial derivatives or fixed price
contracts to manage our exposure to fluctuations in commodity prices and foreign currency exchange rates. A description of such instruments is provided in note 18 of our annual audited consolidated financial statements and related managements
discussion and analysis for the year ended December 31, 
2012, which may be found on SEDAR at www.sedar.com.

Additional Information Concerning
Abandonment & Reclamation Costs

The total future abandonment and reclamation costs are based on managements estimate of
costs to remediate, reclaim and abandon wells and facilities having regard to our Working Interest and the estimated timing of the costs to be incurred in future periods. We have developed a process to calculate these estimates, which considers
applicable regulations, actual and anticipated costs, type and size of the well or facility and the geographic location.

GLJs estimate
of downhole well abandonment costs for all properties as well as abandonment costs for all Sable Island offshore and onshore facilities and pipelines upstream of the plant gate are included in their report and therefore in their estimate of Future
Net Revenue. All other abandonment and reclamation costs are not reflected in GLJs estimate of Future Net Revenue.

We have estimated
the net present value (discounted at ten percent per annum) of our total asset retirement obligations, which are inclusive of those costs estimated by GLJ, to be approximately $138 million as at December 31, 2012, based on a total future
liability (inflated at 1.5 percent per annum) of approximately $2,414 million. These costs are anticipated to be paid over 65 years with the majority of the costs incurred in the last 20 years and applies to 12,721 net wells.

The following table summarizes our total current asset retirement obligations as at December 31, 2012:

The above table excludes asset retirement obligations associated with future development and, in particular, the
development associated with Proved Developed Non-Producing, Proved Undeveloped and Probable Reserves, except where such activity would be coincidental with existing operations. GLJs Proved Developed Producing reserve evaluation at forecast
prices and costs is the best comparison to our current operation and includes $350 million ($129 million when discounted at ten percent) of the current asset retirement obligations in the above table. Elsewhere, where we describe Future Net Revenue,
only the GLJ estimated abandonment obligation is included in the values. For further clarity, the amount beyond the $350 million, or $129 million when discounted at ten percent, is excluded elsewhere.

Tax Horizon

We have not paid cash income tax in the past year and based upon current tax legislation, anticipated capital spending and economic conditions, we do not
anticipate having to pay corporate income tax until at least 2017.

Production Estimates

The following tables summarize the 2013 average daily volume of gross production estimated by GLJ for all properties held on December 31, 2012 using constant and forecast prices and costs, all
of which will be produced in Canada. These estimates assume certain activities take place, such as the development of Undeveloped Reserves, and that there are no dispositions. We estimate our 2013 Company Interest production to be between 85,000 and
87,000 BOE/d.

DESCRIPTION OF CAPITAL STRUCTURE

General

Our authorized capital consists of an unlimited number of Common Shares and 10,000,000 preferred shares, issuable in series (Preferred Shares). The following is a summary of the rights,
privileges, restrictions and conditions attaching to the securities, which comprise our share capital.

Common Shares

Holders of our Common Shares are entitled to notice of, to attend and to one vote per share held at any meeting of our Shareholders
(other than meetings of a class or series of our shares other than the Common Shares as such). Holders of our Common Shares will be entitled to receive dividends as and when declared by our Board on our Common Shares as a class, subject to prior
satisfaction of all preferential rights to dividends attached to shares of other classes of our shares ranking in priority to the Common Shares in respect of dividends. Holders of our Common Shares will be entitled in the event of any liquidation,
dissolution or winding-up of us, whether voluntary or involuntary, or any other distribution of our assets among our Shareholders for the purpose of winding-up our affairs, and subject to prior satisfaction of all preferential rights to return of
capital on dissolution attached to all shares of other classes of our shares ranking in priority to the Common Shares in respect of return of capital on dissolution, to share rateably, together with the holders of shares of any other class of our
shares ranking equally with the Common Shares in respect of return of capital on dissolution, in such of our assets as are available for distribution.

##### Table of Contents

Preferred Shares

The Preferred Shares may be issued in one or more series, at any time or from time to time. Before any shares of a particular series are issued, our Board will fix the number of shares that will form such
series and will, subject to the limitations set out in the preferred share terms described below, fix the designation, rights, privileges, restrictions and conditions to be attached to the Preferred Shares of such series, including, but without in
any way limiting or restricting the generality of the foregoing, the rate, amount or method of calculation of dividends thereon, the time and place of payment of dividends, the consideration for and the terms and conditions of any purchase for
cancellation, retraction or redemption thereof, conversion or exchange rights (if any), and whether into or for our securities or otherwise, voting rights attached thereto (if any), the terms and conditions of any share purchase or retirement plan
or sinking fund, and restrictions on the payment of dividends on any shares other than Preferred Shares or payment in respect of capital on any of our shares or creation or issue of debt or equity securities; the whole subject to filing of Articles
of Amendment setting forth a description of such series including the designation, rights, privileges, restrictions and conditions attached to the shares of such series. Notwithstanding the foregoing: (a) our Board may at any time or from time
to time change the rights, privileges, restrictions and conditions attached to unissued shares of any series of Preferred Shares; and (b) other than in the case of a failure to declare or pay dividends specified in any series of the Preferred
Share, the voting rights attached to the Preferred Shares will be limited to one vote per Preferred Share at any meeting where the Preferred Shares and Common Shares vote together as a single class.

Debentures

DIVIDENDS

General

We currently pay monthly dividends to our Shareholders on the 15thday of each month or the first business day following the 15thday. The record date for any dividend is on or about the 22ndday of the month preceding the dividend date or such other date as may be determined by our Board. In accordance with
stock exchange rules, an ex-dividend date occurs two trading days prior to the record date to permit time for settlement of trades of securities and dividends must be declared a minimum of seven trading days before the record date. A list of all
anticipated dividend record dates for 2013 can be found at www.pengrowth.com/investors/dividends/.

Historical
Distributions/Dividends

Dividends can and may fluctuate in the future. Actual future cash dividends, if any, will be subject to the
discretion of our Board of Directors and may vary depending on a variety of factors and conditions existing from time to time, including fluctuations in commodity prices, production levels, capital expenditure requirements, debt service
requirements, operating costs, royalty burdens, foreign exchange rates and the satisfaction of the liquidity and solvency tests imposed by the ABCA for the declaration and payment of dividends. We cannot provide assurance that cash flow will be
available for distribution to Shareholders in the amounts anticipated or at all. See Risk Factors.

All of these dividends are eligible dividends for the purposes of the Tax Act.

Restrictions on Dividends

Our ability to pay cash dividends to Shareholders may be directly or indirectly affected in certain events as a result of certain restrictions, including restrictions set forth in (i) the credit
agreement relating to our Credit Facility and (ii) the note purchase agreements relating to the 2003 US Senior Notes, the 2007 US Senior Notes, the 2008 Senior Notes, the 2010 Senior Notes, the 2012 Senior Notes and the UK Senior Notes; and
(iii) the solvency tests in the ABCA. In particular, the funds required to satisfy the interest payable on the foregoing obligations, as well as the amounts payable upon the redemption or maturity of such obligations, as applicable, or upon an
Event of Default (as defined below), will be deducted and withheld from the amounts that would otherwise be payable as dividends to Shareholders.

ABCA Solvency Tests

The payment of dividends by a corporation is
governed by the liquidity and insolvency tests described in the ABCA. Pursuant to the ABCA, after the payment of a dividend, we must be able to pay our liabilities as they become due, and the realizable value of our assets must be greater than
our liabilities and the legal stated capital of our outstanding securities. As at December 31, 2012, our legal stated capital was approximately $1.481 billion.

Revolving Credit Facility

The credit agreement relating to the
Credit Facility stipulates that we shall not make or agree to make cash dividends or other distributions to Shareholders when a Default (subject to certain exceptions) or an Event of Default has occurred or is continuing or
would reasonably be expected to occur as a result of such dividend or distribution. Events of Default are defined in the credit agreements to include those events of default typically referred to in a loan agreement of such type and
include, among other things; (i) the failure to repay amounts owing under the Credit Facility; (ii) our voluntary or involuntary insolvency; (iii) the default of obligations owing under other debt arrangements; and (iv) a change
in control of us. Default is defined in the credit agreement to mean any event or circumstance which, with the giving of notice or lapse of time or otherwise, would constitute an Event of Default.

In addition to the standard representations, warranties and covenants commonly contained in a credit facility of this nature, the Credit Facility
includes the following key financial covenants:



| |  |  | The ratio of Consolidated Senior Debt (as defined below) to Consolidated EBITDA (as defined below) at the end of any fiscal quarter shall not exceed
3:1, except upon the completion of a Material Acquisition (as defined below), and for a period extending to the end of the second full fiscal quarter thereafter this limit increases to 3.5:1;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The ratio of Consolidated Total Debt (as defined below) to Consolidated EBITDA at the end of any fiscal quarter shall not exceed 3.5:1; except upon the
completion of a Material Acquisition, and for a period extending to the end of the second full fiscal quarter thereafter, this limit increases to 4:1; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The ratio of Consolidated Senior Debt (as defined below) to Total Capitalization (as defined below) shall not exceed 50 percent, except upon the
completion of a Material Acquisition, and for a period extending to the end of the second fiscal quarter thereafter, this limit increases to 55 percent.

INDUSTRY CONDITIONS

Companies operating in the oil and natural gas industry are subject to extensive regulation and control of operations (including land tenure,
exploration, development, production, refining and upgrading, transportation, and marketing) as a result of legislation enacted by various levels of government and with respect to the pricing and taxation of oil and natural gas through agreements
among the governments of Canada, Alberta, British Columbia, Saskatchewan, Ontario and Nova Scotia, all of which should be carefully considered by investors in the oil and gas industry. It is not expected that any of these regulations or controls
will affect our operations in a manner materially different than they will affect other oil and natural gas companies of similar size. All current legislation is a matter of public record and we are unable to predict what additional legislation or
amendments may be enacted. Outlined below are some of the principal aspects of legislation, regulations and agreements governing the oil and gas industry.

Pricing and Marketing

Oil

The producers of oil are entitled to negotiate sales contracts directly with oil purchasers, with the result that the market determines the price of oil.
Worldwide supply and demand primarily determines oil prices. The specific price depends in part on oil quality, prices of competing fuels, distance to market, availability and cost of transportation capacity to various markets, the value of refined
products, the supply/demand balance, and contractual terms of sale. Oil exporters are also entitled to enter into export contracts with terms not exceeding one year in the case of light crude oil and two years in the case of heavy crude oil,
provided that an order approving such export has been obtained from the National Energy Board of Canada (the NEB). Any oil export to be made pursuant to a contract of longer duration (to a maximum of 25 years) requires an exporter
to obtain an export licence from the NEB. The NEB is currently undergoing a consultation process to update the current regulations governing the issuance of export licences. The updating process is necessary to meet the criteria set out in the
federal Jobs, Growth and Long-term Prosperity Act which received Royal Assent on June 29, 2012 (the Prosperity Act). In this transitory period, the NEB has issued, and is currently following an Interim Memorandum
of Guidance concerning Oil and Gas Export Applications and Gas Import Applications under Part VI of the National Energy Board Act.

Natural Gas

Supply and demand determine the price of natural gas and price is calculated at the sale point, being the wellhead, the outlet of a
gas processing plant, on a gas transmission system such as the Alberta NIT (Nova Inventory Transfer), at a storage facility, at the inlet to a utility system or at the point of receipt by the consumer. Accordingly, the price for natural
gas is dependent upon such producers own arrangements (whether long or short term contracts and the specific point of sale). As natural gas is also traded on trading platforms such as the Natural Gas Exchange (NGX) or the New York Mercantile
Exchange (NYMEX) in the United States, spot and future prices can be set by such supply and demand. Natural gas exported from Canada is subject to regulation by the NEB and the Government of Canada. Exporters are free to negotiate prices and other
terms with purchasers, provided that the export contracts must continue to meet certain other criteria prescribed by the NEB and the Government of Canada. Natural gas (other than propane, butane and ethane) exports for a term of less than two years
or for a term of two to 20 years (in quantities of not more than 30,000 m3/day) must be made pursuant to an NEB order. Any natural gas export to be made pursuant to a contract of longer duration (to a maximum of 25 years) or for a larger quantity requires an exporter to obtain
an export licence from the NEB.

Natural Gas Liquids

In Canada, the price of NGL sold in intraprovincial, interprovincial and international trade is determined by negotiation between buyers and sellers. Such price depends, in part, on the quality of the
NGL, prices of competing chemical feed stock, distance to market, access to downstream transportation, length of contract term, the supply/demand balance and other contractual terms. NGL exported from Canada are subject to regulation by the NEB and
the Government of Canada. Exporters are free to negotiate prices and other terms with purchasers, provided that the export contracts must continue to meet certain criteria prescribed by the NEB and the Government of Canada. NGL may be exported for a
term of no more than one year in respect to propane and butane, and no more than two years in respect to ethane, all exports requiring an order of the NEB.

The North American Free Trade Agreement

The North American Free Trade Agreement (NAFTA) among the governments of Canada, the United States and Mexico became effective on January 1, 1994. In the context of energy resources,
Canada continues to remain free to determine whether exports of energy resources to the United States or Mexico will be allowed, provided that any export restrictions do not: (i) reduce the proportion of energy resources exported relative to
the total supply of goods of the party maintaining the restriction as compared to the proportion prevailing in the most recent 36 month period; (ii) impose an export price higher than the domestic price (subject to an exception with respect to
certain measures which only restrict the volume of exports); and (iii) disrupt normal channels of supply.

All three signatory countries
are prohibited from imposing a minimum or maximum export price requirement in any circumstance where any other form of quantitative restriction is prohibited. The signatory countries are also prohibited from imposing a minimum or maximum import
price requirement except as permitted in enforcement of countervailing and anti-dumping orders and undertakings. NAFTA requires energy regulators to ensure the orderly and equitable implementation of any regulatory changes and to ensure that the
application of those changes will cause minimal disruption to contractual arrangements and avoid undue interference with pricing, marketing and distribution arrangements, all of which are important for Canadian oil and natural gas exports. NAFTA
contemplates the reduction of Mexican restrictive trade practices in the energy sector and prohibits discriminatory border restrictions and export taxes.

Royalties and Incentives

General

In addition to federal regulation, each province has legislation and regulations, which govern royalties, production rates and other matters. The royalty
regime in a given province is a significant factor in the profitability of oil sands projects, crude oil, natural gas liquids, sulphur and natural gas production. Royalties payable on production from lands other than Crown lands are determined by
negotiation between the mineral freehold owner and the lessee, although production from such lands is subject to certain provincial taxes and royalties. Royalties from production on Crown lands are determined by governmental regulation and are
generally calculated as a percentage of the value of gross production. The rate of royalties payable generally depends in part on prescribed reference prices, well productivity, geographical location, field discovery date, method of recovery and the
type or quality of the petroleum product produced. Other royalties and royalty-like interests are carved out of the working interest owners interest, from time to time, through non-public transactions. These are often referred to as overriding
royalties, gross overriding royalties, net profits interests, or net carried interests.

Occasionally the governments of the western Canadian
provinces create incentive programs for exploration and development. Such programs often provide for royalty rate reductions, royalty holidays or royalty tax credits and are generally introduced when commodity prices are low to encourage exploration
and development activity by improving earnings and cash flow within the industry.

Alberta

Producers of oil and natural gas from Crown lands in Alberta are required to pay annual rental payments, currently at a rate of $3.50 per hectare, and
make monthly royalty payments in respect of oil and natural gas produced.

Royalties are currently paid pursuant to The New Royalty
Framework (implemented by the Mines and Minerals (New Royalty Framework) Amendment Act, 2008) and the Alberta Royalty Framework, which was implemented in 2010.

Royalty rates for conventional oil are set by a single sliding rate formula, which is applied monthly and incorporates separate
variables to account for production rates and market prices. Effective January 1, 2011, the maximum royalty payable under the royalty regime was set at 40%. The royalty curve for conventional oil announced on May 27, 2010 amends the price
component of the conventional oil royalty formula to moderate the increase in the royalty rate at prices higher than
$535/m3compared to the previous royalty curve.

Royalty rates for natural gas under the royalty regime are similarly determined using a single sliding rate formula incorporating separate
variables to account for production rates and market prices. Effective January 1, 2011, the maximum royalty payable under the royalty regime was set at 36%. The royalty curve for natural gas announced on May 27, 2010 amends the price
component of the natural gas royalty formula to moderate the increase in the royalty rate at prices higher than $5.25/GJ compared to the previous royalty curve.

Oil sands projects are also subject to the Albertas royalty regime. Prior to payout of an oil sands project, the royalty is payable on gross revenues of an oil sands project. Gross revenue royalty
rates range between 1-9% depending on the market price of oil, determined using the average monthly price, expressed in Canadian dollars, for WTI crude oil and Cushing, Oklahoma: rates are 1% when the market price of oil is less than or equal to $55
per barrel and increase for every dollar of market price of oil increase to a maximum of 9% when oil is priced at $120 or higher. After payout, the royalty payable is the greater of the gross revenue royalty based on the gross revenue royalty rate
of 1-9% and the net revenue royalty based on the net revenue royalty rate. Net revenue royalty rates start at 25% and increase for every dollar of market price of oil increase above $55 up to 40% when oil is priced at $120 or higher. In addition,
concurrently with the implementation of the New Royalty Framework, the Government of Alberta renegotiated existing contracts with certain oil sands producers that were not compatible with the current royalty regime.

##### Table of Contents

Producers of oil and natural gas from freehold lands in Alberta are required to pay annual freehold
production taxes. The level of the freehold production tax is based on the volume of monthly production and a specified rate of tax for both oil and gas.

The Innovative Energy Technologies Program (the IETP), which is currently in place, has the stated objectives of increasing recovery from oil and gas deposits, finding technical
solutions to the gas over bitumen issue, improving the recovery of bitumen by in-situ and mining techniques and improving the recovery of natural gas from coal seams. The IETP provides royalty adjustments to specific pilot and demonstration projects
that utilize new or innovative technologies to increase recovery from existing reserves.

The Government of Alberta currently has in place two
royalty programs, both of which commenced in 2008 with the intention to encourage the development of deeper, higher cost oil and gas reserves. A five-year program for conventional oil exploration wells over 2,000 metres provides qualifying wells
with up to a $1 million or 12 months of royalty relief, whichever comes first, and a five-year program for natural gas wells deeper than 2,500 metres provides a sliding scale royalty credit based on depth of up to $3,750 per metre. On May 27,
2010, the natural gas deep drilling program was amended, retroactive to May 1, 2010, by reducing the minimum qualifying depth to 2,000 metres, removing a supplemental benefit of $875,000 for wells exceeding 4,000 metres that are spudded
subsequent to that date, and including wells drilled into pools drilled prior to 1985, among other changes.

On November 19, 2008, the
Government of Alberta announced the introduction of a five-year program of transitional royalty rates with the intent of promoting new drilling. The five-year transition option is designed to provide lower royalties at certain price levels in the
initial years of a wells life when production rates are expected to be the highest. Under this program, companies drilling new natural gas or conventional deep oil wells between 1,000 and 3,500 m receive a one-time option, on a well-by-well
basis, to adopt either the new transitional royalty rates or those outlined in the royalty regime. These options expired on February 15, 2011 and on January 1, 2014, all producers operating under the transitional royalty rates will
automatically become subject to the royalty regime. Production from wells operating under the transitional royalty rates will not be subject to the royalty curves for conventional oil and natural gas.

On March 17, 2011, the Government of Alberta approved the New Well Royalty Regulationproviding for the permanent
implementation of a formerly temporary royalty program which provides for a maximum 5% royalty rate for eligible new wells for the first twelve (12) productive months or until the regulated volume cap is reached.

In addition to the foregoing, the Government of Alberta has implemented certain initiatives intended to accelerate technological development and
facilitate the development of unconventional resources (the Emerging Resource and Technologies Initiative). Specifically:



| |  |  | Coalbed methane wells will receive a maximum royalty rate of 5% for 36 producing months on up to 750 MMcf of production, retroactive to wells that
began producing on or after May 1, 2010;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Shale gas wells will receive a maximum royalty rate of 5% for 36 producing months with no limitation on production volume, retroactive to wells that
began producing on or after May 1, 2010;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Horizontal gas wells will receive a maximum royalty rate of 5% for 18 producing months on up to 500 MMcf of production, retroactive to wells that
commenced drilling on or after May 1, 2010; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Horizontal oil wells and horizontal non-project oil sands wells will receive a maximum royalty rate of 5% with volume and production month limits set
according to the depth of the well (including the horizontal distance), retroactive to wells that commenced drilling on or after May 1, 2010.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Emerging Resource and Technologies Initiative will be reviewed in 2014, and the Government of Alberta has committed to providing industry with three years notice at that time if it decides to
discontinue the program.

Approximately 77 percent of our Company Interest production forecast for 2012 is in the Province of Alberta on Crown
lands.

British Columbia

Producers of oil and natural gas from Crown lands in British Columbia are required to pay annual rental payments, currently at a rate of $3.50 per hectare, and make monthly royalty payments in respect of
oil and natural gas produced. The amount payable as a royalty in respect of oil depends on the type and vintage of the oil, the quantity of oil produced in a month and the value of that oil. Generally, oil is classified as either light or heavy and
the vintage of oil is based on the determination of whether the oil is produced from a pool discovered before October 31, 1975 (old oil), between October 31, 1975 and June 1, 1998 (new oil), or
after June 1, 1998 or through an Enhanced Oil Recovery (EOR) Scheme (third-tier oil). The royalty calculation takes into account the production of oil on a well-by-well basis, the specified royalty rate for
a given vintage of oil, the average unit selling price of the oil and any applicable royalty exemptions. Royalty rates are reduced on low productivity wells, reflecting the higher unit costs of extraction, and are the lowest for third-tier oil,
reflecting the higher unit costs of both exploration and extraction.

##### Table of Contents

The royalty payable in respect of natural gas produced on Crown lands is determined by a sliding scale
formula based on a reference price, which is the greater of the average net price obtained by the producer and a prescribed minimum price. For non-conservation gas (not produced in association with oil), the royalty rate depends on the date of
acquisition of the oil and natural gas tenure rights and the spud date of the well and may also be impacted by the select price, a parameter used in the royalty rate formula to account for inflation. Royalty rates are fixed for certain classes of
non-conservation gas when the reference price is below the select price. Conservation gas is subject to a lower royalty rate than non-conservation gas. Royalties on natural gas liquids are levied at a flat rate of 20% of the sales volume.

Producers of oil and natural gas from freehold lands in British Columbia are required to pay monthly freehold production taxes. For oil, the
level of the freehold production tax is based on the volume of monthly production. It is either a flat rate, or, at certain production levels, is determined using a sliding scale formula based on the reference price similar to that applied to oil
production on Crown land. For natural gas, the freehold production tax is either a flat rate, or, at certain production levels, is determined using a sliding scale formula based on the reference price similar to that applied to natural gas
production on Crown land, and depends on whether the natural gas is conservation gas or non-conservation gas. The freehold production tax rate for natural gas liquids is a flat 12.25%.

British Columbia maintains a number of targeted royalty programs for key resource areas intended to increase the competitiveness of British Columbias natural gas low productivity wells. These
include both royalty credit and royalty reduction programs, including the following:



| |  |  | Summer Royalty Credit Program providing a royalty credit equal to 10% of the goods and services costs up to $100,000 for wells drilled between
April 1 and November 30 of each year;

certain other criteria are met and is intended to reflect the higher drilling and completion costs that relate to locations specific factors;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Deep Re-Entry Royalty Credit Program providing royalty credit for deep re-entry wells with a true vertical depth to the top of pay of the
re-entry well event that is greater than 2,300 metres and a re-entry date subsequent to December 1, 2003; or if the well was spud on or after January 1, 2009, with a true vertical depth to the completion point of the re-entry well event

depth greater than 4,000 metres whose surface locations are at least 20 kilometres away from the surface location of any well drilled into a recognized pool within the same formation;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Natural Gas Royalty Reduction providing a reduced royalty on wells drilled on land rights acquired after June 1, 1998 and completed within
5 years of the date the rights are issued;

wells equal to $50,000 for wells drilled on Crown land and a tax credit equal to $30,000 for wells drilled on freehold land;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Marginal Royalty Reduction Program providing monthly royalty reductions for low productivity non-conservation natural gas wells with average
monthly production under 25,000 m3during the first 12
production months and average daily production less than 23 m3for every metre of marginal well depth;

Oil produced from an oil well that is located on either Crown or freehold land and completed in a new pool discovered subsequent to
June 30, 1974 may also be exempt from the payment of a royalty for the first 36 months of production or 11,450 m3of production, whichever comes first.

The Government of British Columbia also maintains an Infrastructure Royalty Credit Program (the
Infrastructure Royalty Credit Program) which provides royalty credits for up to 50% of the cost of certain approved road construction or pipeline infrastructure projects intended to facilitate increased oil and gas exploration and
production in under-developed areas and to extend the drilling season.

In August 2012, the Government of British Columbia announced that it
is bringing in a nominal 2% royalty on both oil and natural gas on the revenue for the first year of production for wells drilled from September 2012 through to June 2013.

Approximately ten percent of our Company Interest production forecast for 2012 is in the Province of British Columbia on Crown lands.

Saskatchewan

In Saskatchewan, the amount payable as Crown royalty or freehold
production tax in respect of oil depends on the type and vintage of oil, the quantity of oil produced in a month, the value of the oil produced and specified adjustment factors determined monthly by the provincial government. For Crown royalty and
freehold production tax purposes, conventional oil is divided into types, being heavy oil, southwest designated oil or non-heavy oil other than southwest designated oil. The conventional royalty and
production tax classifications (fourth tier oil, third tier oil, new oil and old oil) depend on the finished drilling date of a well and are applied to each of the three crude oil types slightly
differently. Heavy oil is classified as third tier oil (having a finished drilling date on or after January 1, 1994 and before October 1, 2004), fourth tier oil (having a finished drilling date on or after October 1, 2002 or
incremental oil from new or expanded waterflood projects) or new oil (oil from wells drilled on or after January 1, 1994 ). Southwest designated oil uses the same definitions of third and fourth tier oil but new oil is defined as conventional
oil produced from a horizontal well having a finished drilling date on or after February 9, 1998 and before October 1, 2002. For non-heavy oil other than southwest designated oil, the same classification is used but new oil is defined as
conventional oil produced from a vertical well completed after 1973 and having a finished drilling date prior to 1994, whereas old oil is defined as conventional oil not classified as third or fourth tier oil or new oil. Production tax rates for
freehold production are determined by first determining the Crown royalty rate and then subtracting the Production Tax Factor (PTF) applicable to that classification of oil. Currently the PTF is 6.9 for old
oil, 10.0 for new oil and third tier oil and 12.5 for fourth tier oil. The minimum rate for freehold production tax is zero.

Base prices are used to establish lower limits in the price-sensitive royalty structure for conventional oil and apply at a reference well production rate of 100 m3for old oil, new oil and third tier
oil, and 250 m3per month for fourth tier
oil. Where average wellhead prices are below the established base prices of $100 per m3for third and fourth tier oil and $50 per m3for new oil and old oil, base royalty rates are applied. Base royalty rates are 5% for all fourth tier oil, 10% for heavy oil that is third tier oil or new oil, 12.5% for southwest designated oil that is
third tier oil or new oil, 15% for non-heavy oil other than southwest designated oil that is third tier or new oil, and 20% for old oil. Where average wellhead prices are above base prices, marginal royalty rates are applied to the proportion of
production that is above the base oil price. Marginal royalty rates are 30% for all fourth tier oil, 25% for heavy oil that is third tier oil or new oil, 35% for southwest designated oil that is third tier oil or new oil, 35% for non-heavy oil other
than southwest designated oil that is third tier or new oil, and 45% for old oil.

The amount payable as Crown royalty or
freehold production tax in respect of natural gas production is determined by a sliding scale based on the actual price received, the quantity produced in a given month, the type of natural gas, and the classification of the natural gas. Like
conventional oil, natural gas may be classified as non-associated gas (gas produced from gas wells) or associated gas (gas produced from oil wells) and royalty rates are determined according to the finished drilling date of
the respective well. Non-associated gas is classified as new gas (having a finished drilling date before February 9, 1998 with a first production date on or after October 1, 1976), third tier gas (having a finished drilling date on or
after February 9, 1998 and before October 1, 2002), fourth tier gas (having a finished drilling date on or after October 1, 2002) and old gas (not classified as either third tier, fourth tier or new gas). A similar classification is
used for associated gas except that the classification of old gas is not used, the definition of fourth tier gas also includes production from oil wells with a finished drilling date prior to October 1, 2002, where the individual oil well has a
gas-oil production ratio in any month of more than 3,500
m3of gas for every m3of oil, and new gas is defined as oil produced from a well with a
finished drilling date before February 9, 1998 that received special approval, prior to October 1, 2002, to produce oil and gas concurrently without gas-oil ratio penalties. Natural gas liquids and by-products recovered at gas processing
plants are not subject to a royalty. Gas liquids which are produced and measured at the wellhead are treated as crude oil for royalty purposes.

On December 9, 2010, the Government of Saskatchewan enacted the Freehold Oil and Gas Production Tax Act, 2010 with the intention to
facilitate the efficient payment of freehold production taxes by industry. Two new regulations with respect to this legislation are: (i) The Freehold Oil and Gas Production Tax Regulations, 2012 which sets out the terms and conditions
under which the taxes are calculated and paid; and (ii) The Recovered Crude Oil Tax Regulations, 2012 which sets out the terms and conditions under which taxes on recovered crude oil that was delivered from a crude oil recovery facility
on or after March 1, 2012 are to be calculated and paid.

As with conventional oil production, base prices based on
a well reference rate of 250 103m3/month are used to establish lower limits in the price-sensitive
royalty structure for natural gas. Where average field-gate prices are below the established base prices of $50 per thousand m3for third and fourth tier gas and $35 per thousand m3for new gas and old gas, base royalty rates are applied. Base royalty rates are 5% for all fourth tier gas, 15% for
third tier or new gas, and 20% for old gas. Where average well-head prices are above base prices, marginal royalty rates are applied to the proportion of production that is above the base gas price. Marginal royalty rates are 30% for all fourth tier
gas, 35% for third tier and new gas, and 45% for old gas.The current regulatory scheme provides forcertain differences with respect to the administration of forth tier gas which is associated gas.

In 1975, the Government of Saskatchewan introduced a Royalty Tax Rebate (RTR) as a response to the Government of Canada disallowing
Crown royalties and similar taxes as a deductible business expense for income tax purposes. As of January 1, 2007, the remaining balance of any unused RTR is limited in its carry forward to seven years because of the Government of Canadas
initiative to reintroduce the full deduction of provincial resource royalties from federal and provincial taxable income.

On June 22,
2011, the Government of Saskatchewan released the Upstream Petroleum Industry Associated Gas Conservation Standards, which are designed to reduce emissions resulting for the flaring and venting of associated gas (the Associated Natural Gas
Standards). The Associated Natural Gas Standards were jointly developed with industry and the implementation of such standards commenced on July 1, 2012 for new wells and facilities licensed on or after such date. These will apply to
existing licensed wells and facilities on July 1, 2015.

Approximately seven percent of our Company Interest production forecast for 2012
is in the Province of Saskatchewan.

Ontario

In Ontario, the Crown royalty rate for oil and gas is 12.5%, based on monthly production and full sale price of the oil or gas received at the point of sale.

Nova Scotia

The Government of Nova Scotia has established a generic royalty regime in respect of oil and gas produced from offshore Nova Scotia based on revenues and profits. Such regime contemplates a multi-tier
royalty in which the royalty rate fluctuates when certain threshold levels of rates of return on capital have been reached and offers lower royalties for a first project in a new area, being a high risk project. Notwithstanding the
generic royalty regime, royalties in respect of offshore Nova Scotia oil and gas production may be determined contractually between the participant and the Government of Nova Scotia.

Approximately five percent of our Company Interest production forecast for 2012 is in the Province of Nova Scotia.

Land Tenure

The respective provincial governments predominantly own crude oil and natural
gas located in the western provinces. Provincial governments grant rights to explore for and produce oil and natural gas pursuant to leases, licences, and permits for varying terms, and on conditions set forth in provincial legislation including
requirements to perform specific work or make payments. Private ownership of oil and natural gas also exists in such provinces and rights to explore for and produce such oil and natural gas are granted by lease on such terms and conditions as may be
negotiated.

Each of the provinces of Alberta, British Columbia and Saskatchewan has implemented legislation providing for the reversion to
the Crown of mineral rights to deep, non-productive geological formations at the conclusion of the primary term of a lease or license. On March 29, 2007, British Columbia expanded its policy of deep rights reversion for new leases to provide
for the reversion of both shallow and deep formations that cannot be shown to be capable of production at the end of their primary term.

Alberta also has a policy of shallow rights reversion which provides for the reversion to the Crown of mineral rights to shallow,
non-productive geological formations for all leases and licenses. For leases and licenses issued subsequent to January 1, 2009, shallow rights reversion will be applied at the conclusion of the primary term of the lease or license. Holders of
leases or licences that have been continued indefinitely prior to January 1, 2009 will receive a notice regarding the reversion of the shallow rights, which will be implemented three years from the date of the notice. Leases and licences
granted prior to January 1, 2009, but continued after that date, are not subject to shallow rights reversion until they continue past their primary term (at which time the application of deep rights reversion occurs). Afterwards, the holders of
such agreements will be served with shallow rights reversion notices based on vintage and location similar to leases and licences that were already continued as of January 1, 2009. The order in which these agreements will receive reversion
notices will depend on their vintage and location.

Environmental Regulation

The oil and natural gas industry is currently subject to environmental regulations pursuant to a variety of provincial and federal legislation, all of which is subject to governmental review and revision
from time to time. Such legislation provides for restrictions and prohibitions on the release or emission of various substances produced in association with certain oil and gas industry operations, such as sulphur dioxide and nitrous oxide. In
addition, such legislation sets out the requirements for the satisfactory abandonment and reclamation of well and facility sites. Compliance with such legislation can require significant expenditures and a breach of such requirements may result in
suspension or revocation of necessary licenses and authorizations, civil liability for pollution damage, and the imposition of material fines and penalties.

On a Federal level and pursuant the Prosperity Act, in June 2012, the Government of Canada amended or appealed several pieces of federal environmental legislation and in addition, created a new federal
environment assessment regime. The changes to the environmental legislation under the Prosperity Act are intended to provide for more efficient and timely environmental assessments of projects that previously had been subject to overlapping
legislative jurisdiction.

In December 2008, the Government of Alberta released a new land use policy for surface land in Alberta, the Alberta
Land Use Framework (the ALUF). The ALUF sets out an approach to manage public and private land use and natural resource development in a manner that is consistent with the long-term economic, environmental and social goals of the
province. It calls for the development of region-specific land use plans in order to manage the combined impacts of existing and future land use within a specific region and the incorporation of a cumulative effects management approach into such
plans.

The Alberta Land Stewardship Act (the ALSA) was proclaimed in force in Alberta on October 1, 2009 and
provides the legislative authority for the Government of Alberta to implement the policies contained in the ALUF. Regional plans established pursuant to the ALSA will be deemed to be legislative instruments equivalent to regulations and will be
binding on the Government of Alberta and provincial regulators, including those governing the oil and gas industry. In the event of a conflict or inconsistency between a regional plan and another regulation, regulatory instrument or statutory
consent, the regional plan will prevail. Further, the ALSA requires local governments, provincial departments, agencies and administrative bodies or tribunals to review their regulatory instruments and make any appropriate changes to ensure that
they comply with an adopted regional plan. The ALSA also contemplates the amendment or extinguishment of previously issued statutory consents such as regulatory permits, leases, licenses, approvals and authorizations for the purpose of achieving or
maintaining an objective or policy resulting from the implementation of a regional plan. Among the

measures to support the goals of the regional plans contained in the ALSA are conservation easements, which can be granted for the protection, conservation and enhancement of land; and
conservation directives, which are explicit declarations contained in a regional plan to set aside specified lands in order to protect, conserve, manage and enhance the environment.

On August 22, 2012, the Government of Alberta approved the Lower Athabasca Regional Plan (LARP) which came into effect on September 1, 2012. The LARP covers approximately
93,212 square kilometres and is in the northeast corner of Alberta. The region includes a substantial portion of the Athabasca oilsands area, which contains approximately 82% of the provinces oilsands resource and much of the Cold Lake oilsands
area. LARP establishes six new conservation areas, bringing the total conserved land in the region to two million hectares, or 22%an area three times the size of Banff National Park. The Alberta government plans to pay $30 million to producers
whose leases will be cancelled in areas set aside for conservation. Oil and gas companies will be allowed to continue to operate in conservation and recreation areas while oilsands companies tenures will be cancelled. New petroleum and gas
tenure sold in conservation areas will include a restriction that prohibits surface access. Application procedures for activities and facilities in the LARP, regulated by the Energy Resources Conservation Board and the Alberta Utilities Commission,
respectively, have been changed to accommodate the new restrictions set out in the LARP. The LARP is the first of seven regions to get a land use plan. The next will be the South Saskatchewan region.

In British Columbia, the Oil and Gas Activities Act (the OGCA) impacts conventional oil and gas producers, shale gas producers,
and other operators of oil and gas facilities in B.C. Under the OGCA, the B.C. Oil and Gas Commission has broad powers, particularly with respect to compliance and enforcement and the setting of technical safety and operational standards for oil and
gas activities. The Environmental Protection and Management Regulation establishes the governments environmental objectives for water, riparian habitats, wildlife and wildlife habitat, old-growth forests and cultural heritage resources.
The OGCA requires the Commission to consider these environmental objectives in deciding whether or not to authorize an oil and gas activity. In addition, although not an exclusively environmental statute, the Petroleum and Natural Gas Act
requires proponents to obtain various approvals before undertaking exploration or production work, such as geophysical licences, geophysical exploration project approvals, and permits for the exclusive right to do geological work and geophysical
exploration work, and well, test hole, and water-source well authorizations. Such approvals are given subject to environmental considerations and licences and project approvals can be suspended or cancelled for failure to comply with this
legislation or its regulations.

In May of 2011, Saskatchewan passed changes to The Oil and Gas Conservation Act(SKOGCA), the act governing the regulation of resource development operations in the province. Although the associated Bill received Royal Assent on May 18, 2011, it was not proclaimed into force until April 1, 2012,
in conjunction with the release of The Oil and Gas Conservation Regulations, 2012 (OGCR) and The Petroleum Registry and Electronic Documents Regulations (Registry Regulations). The aim of the
amendments to the SKOGCA, and associated regulations, is to provide resource companies investing in Saskatchewans energy and resource industries with the best support services and business and regulatory systems available. With the enactment
of the Registry Regulations and the OGCR, Saskatchewan has implemented a number of operational aspects, including the increased demand for record-keeping, increased testing requirements for injection wells and increased investigation and enforcement
powers; and, procedural aspects including those related to Saskatchewans participation as partner in the Petroleum Registry of Alberta.

Climate Change Regulation

Federal

On April 26, 2007, the Government of Canada released Turning the Corner: An Action Plan to Reduce Greenhouse Gases and Air
Pollution (the Action Plan) which set forth a plan for regulations to address both GHGs and air pollution. An update to the Action Plan, Turning the Corner: Regulatory Framework for Industrial Greenhouse Gas
Emissions was released on March 10, 2008 (the Updated Action Plan). The Updated Action Plan outlines emissions intensity-based targets, which will be applied to regulated sectors on a facility-specific, sector-wide or a
company-by-company basis. Facility-specific targets apply to the upstream oil and gas, oil sands, petroleum refining and natural gas pipelines sectors. Unless a minimum regulatory threshold applies, all facilities within a regulated sector will be
subject to the emissions intensity targets. Although the intention was for draft regulations for the implementation of the Updated Action Plan to become binding on January 1, 2010, the only regulations announced pertain to carbon dioxide
emissions from coal-fired generation of electricity (finalized in summer 2012). Further, representatives of the Government of Canada have indicated that the proposals contained in the Updated Action Plan will be modified to ensure consistency with
the direction ultimately taken by the United States with respect to GHG emissions regulation. As a result, it is unclear to what extent implementation of the proposals contained in the Updated Action Plan will occur.

The United States Environmental Protection Agency (the EPA) has indicated its intention to impose GHG emissions standards for fossil
fuel-fired power plants by specifying that it would issue final regulations by May 26, 2012, and with respect to refineries, specifying that it will issue proposed regulations by December 10, 2011 and finalized regulations by
November 10, 2012. The EPA did not meet the December 10, 2011 deadline and it is unclear whether the EPA will also miss the finalized regulations deadline. However, in March 2012, the EPA proposed a strict GHG standard on new power plants
only. While it is expected that this rule could encourage building new natural gas power plants rather than coal plants, the actual effect of the new rule will not be able to be quantified for some time.

Alberta

Alberta enacted the Climate Change and Emissions Management Act(the CCEMA) on December 4, 2003, amending it through the Climate Change and Emissions Management Amendment
Act, which received royal assent on November 4, 2008. The CCEMA is based on an emissions intensity approach similar to the Updated Action Plan and aims for a 50% reduction from 1990 emissions relative to GDP by 2020.

Alberta facilities emitting more than 100,000 tonnes of GHGs a year are subject to compliance with the CCEMA. Similar to the Updated Action Plan, the
CCEMA and the associated Specified Gas Emitters Regulation make a distinction between Established Facilities and New Facilities. Established Facilities are defined as facilities that completed their first year of
commercial operation prior to January 1, 2000 or that have completed eight or more years of commercial operation. Established Facilities are required to reduce their emissions intensity to 88% of their baseline for 2008 and subsequent years,
with their baseline being established by the average of the ratio of the total annual emissions to production for the years 2003 to 2005. New Facilities are defined as facilities that completed their first year of commercial operation on
December 31, 2000, or a subsequent year, and have completed less than eight years of commercial operation, or are designated as New Facilities in accordance with the Specified Gas Emitters Regulation. New Facilities are required to
reduce their emissions intensity by 2% from baseline in the fourth year of commercial operation, 4% of baseline in the fifth year, 6% of baseline in the sixth year, 8% of baseline in the seventh year, and 10% of baseline in the eighth year. Unlike
the Updated Action Plan, the CCEMA does not contain any provision for continuous annual improvements in emissions intensity reductions beyond those stated above.

The CCEMA contains compliance mechanisms that are similar to the Updated Action Plan. Regulated emitters can meet their emissions intensity targets by contributing to the Climate Change and Emissions
Management Fund at a rate of $15 per tonne of CO2equivalent.
Unlike the Updated Action Plan, CCEMA contains no provisions for an increase to this contribution rate. Emissions credits can be purchased from regulated emitters that have reduced their emissions below the 100,000 tonne threshold or non-regulated
emitters that have generated emissions offsets through activities that result in emissions reductions in accordance with established protocols published by the Government of Alberta.

On December 2, 2010, the Government of Alberta passed theCarbon Capture and Storage Statutes Amendment Act, 2010. It deemed the pore space underlying all land in Alberta to be, and to have
always been, the property of the Crown and provided for the assumption of long-term liability for carbon sequestration projects by the Crown, subject to the satisfaction of certain conditions.

Under the Alberta regulations, if the emissions remain at current levels, we would be required to purchase off-setting credits in 2013 of up
to $500,000 from Alberta Environment. In 2011 our Olds Gas Plant and Judy Creek Gas Conservation Plant did not need to purchase off-setting credits as we had a surplus of carbon credits.

British Columbia

In February 2008, British Columbia announced a revenue-neutral carbon tax that took effect July 1, 2008. The tax is consumption-based and applied at the time of retail sale or consumption of
virtually all fossil fuels purchased or used in British Columbia. The current tax level is $30 per tonne of CO2equivalent. The final scheduled increase took effect on July 1, 2012. There is no plan for further rate increases or expansions at this time. In order to make the tax revenue-neutral, British
Columbia has implemented tax credits and reductions in order to offset the tax revenues that the Government of British Columbia would otherwise receive from the tax.

In their 2012 Budget, British Columbia announced the government will undertake a comprehensive review of the carbon tax and its impact on British Columbians. The review will cover all aspects of the
carbon tax, including revenue neutrality, and will consider the impact on the competitiveness of B.C. businesses such as those in the agriculture sector, and in particular, B.C.s food producers. Under this comprehensive review, British
Columbians can make written submissions to B.C.s Minister of Finance, and these will be considered as part of the 2013 Budget process.

On April 3, 2008, British Columbia introduced the Greenhouse Gas Reduction (Cap and Trade) Act (the Cap and Trade Act)
which received royal assent on May 29, 2008 and partially came into force by regulation of the Lieutenant Governor in Council. It sets a province-wide target of a 33% reduction in the 2007 level of GHG emissions by 2020 and an 80% reduction by
2050. Unlike the emissions intensity approach taken by the federal government and the Government of Alberta, the Cap and Trade Act establishes an absolute cap on GHG emissions. The Cap and Trade Act sets out the requirements for the reporting of the
greenhouse gas emissions from facilities in British Columbia emitting 10,000 tonnes or more of carbon dioxide equivalent emissions per year beginning on January 1, 2010. Those reporting operations with emissions of 25,000 tonnes or greater are
required to have emissions reports verified by a third party. Recent amendments to the Act repealed past requirements on public-sector organizations, including Crown corporations, to be carbon neutral by 2010, and they are now only required to
produce annual carbon reduction plans and reports. Additional regulations that will further enable British Columbia to implement a cap and trade system are currently under further development.

We do not currently have any facilities that emit over 10,000 tonnes of CO2but we do trigger the Linear Facility definition as we conduct oil and
gas extraction and gas processing activities in British Columbia that cumulatively exceed the threshold. As a result, we are required to report our emissions.

Saskatchewan

On May 11, 2009, the Government of Saskatchewan announced The
Management and Reduction of Greenhouse Gases Act(the MRGGA) to regulate GHG emissions in the province. The MRGGA received Royal Assent on May 20, 2010 and will come into force on proclamation. Regulations under the MRGGA
have also yet to be proclaimed, but draft versions indicate that Saskatchewan will adopt the goal of a 20% reduction in GHG emissions from 2006 levels by 2020.

Ontario

The Province of Ontario has not implemented GHG emission reduction
legislation applicable to the oil and gas industry at this time. Ontarios Climate Change Action Plan calls for a 6% reduction by 2014 and a 15% reduction by 2020 from 1990 levels. Ontario plans to achieve these reductions with the
implementation of a cap and trade system and by phasing out coal-fired electrical power plants, among other measures.

The Environmental Protection Acthas been amended to include provisions to enable a cap and trade system and as of
January 1, 2010 emitters of more than 25,000 tonnes of CO2eper year must report their emissions to the government pursuant to Ontario Regulation 452/09 (Ontario Greenhouse Gas Emissions Reporting).

Nova Scotia

The Province of Nova Scotia has set a goal of lowering greenhouse gas
emissions by 10 percent below 1990 levels by 2020 and has implemented the Environmental Goals and Sustainable Prosperity Act. The Crown must report annually the amount of reductions achieved in the Province but there is no mechanism for measuring
compliance nor are there any consequences for failing to meet the goal.

General Discussion

As present, we are not paying any direct costs. However, the direct and indirect costs of the various GHG regulations, existing and proposed, may at some
time and under certain conditions adversely affect our business, operations and financial results. Equipment that meets future emission standards may not be available on an economic basis and other compliance methods to reduce our emissions or
emissions intensity to future required levels may significantly increase operating costs or reduce the output of the projects. Offset, performance or fund credits may not be available for acquisition or may not be available on an economic basis. Any
failure to meet emission reduction compliance obligations requirements may materially adversely affect our business and result in fines, penalties and the suspension of operations. There is also a risk that one or more levels of government could
impose additional emissions or emissions intensity reduction requirements or taxes on emissions created by us or by consumers of our products. The imposition of such measures might negatively affect our costs and prices for our products and have an
adverse effect on earnings and results of operations.

RISK FACTORS

If any of the following risks occur, our production, revenues and financial condition could be materially impaired, with a resulting decrease in
dividends on, and the market price of, our Common Shares. As a result, the trading price of our Common Shares could decline, and you could lose all or part of your investment. Additional risks are described under the heading Business
Risks in our Managements Discussion and Analysis for the year ended December 31, 2012.

The trading price of our
Common Shares is subject to substantial volatility often based on factors related and unrelated to our financial performance or prospects.

Factors unrelated to our performance could include macroeconomic developments nationally, within North America or globally, domestic and global commodity
prices or current perceptions of the oil and gas market. Similarly, the market price of our Common Shares could be subject to significant fluctuations in response to variations in our operating results, financial condition, liquidity and other
internal factors. Factors that could affect the market price of our Common Shares that are unrelated to our performance include domestic and global commodity prices and market perceptions of the attractiveness of particular industries. The price at
which our Common Shares will trade cannot be accurately predicted.

Low oil and natural gas prices could have a material adverse effect on
our results of operations and financial condition, which, in turn, could negatively affect the amount of dividends to our Shareholders and the market price of the Common Shares.

The monthly dividends we pay to our Shareholders and the market price of the Common Shares depend, in part, on the prices we receive for our oil and natural gas production. Oil and natural gas prices can
fluctuate widely on a month-to-month basis in response to a variety of factors that are beyond our control. While oil prices are set in a much broader global market, natural gas prices are largely dependent on North American economies. Additional
factors include:

North American crude oil price differentials are expected to continue to be volatile throughout 2013 which will have an impact on crude oil prices for
Canadian producers. Overall, supply in excess of current pipeline and refining capacity is expected to exist. Material structural changes are required to reduce these bottlenecks and the resulting steep price discounts. There are numerous projects
proposed to alleviate pipeline bottlenecks in the United States, expand refinery capacity and expand or build new pipelines in Canada and the United States to source new markets, many of which are in the regulatory application phase. There can be no
assurance that such regulatory approvals will be secured on a timely basis or at all.

Declines in oil or natural gas prices could have a
materially adverse effect on our operations, financial condition and proved reserves and ultimately on the market price of the Common Shares and our ability to pay dividends to our Shareholders.

The amount of future dividends, if any, may vary.

The amount of future dividends paid by us, if any, will be subject to the discretion of our Board of Directors and may vary depending on a variety of factors, forecasts and conditions existing from time
to time, including fluctuations in commodity prices, production levels, capital expenditure requirements, debt service requirements, operating costs, royalty burdens, foreign exchange rates and the satisfaction of the liquidity and solvency tests
imposed by the ABCA for the declaration and payment of dividends. Depending on these and various other factors, many of which will be beyond our control, we may change our dividend policy from time to time and, as a result, future dividends could be
reduced or suspended entirely.

The market value of the Common Shares may deteriorate if dividends are reduced or suspended. Furthermore, the
future treatment of dividends for tax purposes will be subject to the nature and composition of dividends paid by us and potential legislative and regulatory changes. Dividends may be reduced during periods of lower funds from operations, which
result from lower commodity prices and any decision by us to finance capital expenditures using funds from operations.

Dividends may be
reduced during periods of lower operating cash flow, which result from lower commodity prices and the decisions by us to otherwise use cash flow.

To the extent that external sources of capital, including the issuance of additional Common Shares, become limited or unavailable, our ability to make the necessary capital investments to maintain or
expand petroleum and natural gas reserves and to invest in assets, as the case may be, will be impaired. To the extent that we are required to use funds from operations to finance capital expenditures or property acquisitions, the cash available for
dividends may be reduced.

Our success depends in large measure on certain key and qualified personnel.

The loss of the services of key personnel may have a material adverse effect on our business, financial condition, results of operations and prospects.
The contributions of the existing management team to our immediate and near term operations are likely to be of central importance. In addition, the competition for qualified personnel in the oil and natural gas industry is intense and there can be
no assurance that we will be able to continue to attract and retain all personnel necessary for the development and operation of our business. Investors must rely upon the ability, expertise, judgment, discretion, integrity and good faith of our
management.

Actual production, reserves and resources will vary from estimates, and those variations could be
material and may negatively affect the market price of the Common Shares and dividends to our Shareholders.

The value of the Common
Shares will depend upon, among other things, our reserves and resources. In making strategic decisions, we rely upon reports prepared by our independent reserve engineers and our own internal estimates. Estimating future production, reserves and
resources is inherently uncertain. Ultimately, actual production, revenues and expenditures for the underlying properties will vary from estimates and those variations could be material. Changes in the prices of, and markets for, oil and natural gas
from those anticipated at the time of making such assessments will affect the return on, and value of, our Common Shares. The reserves, resources and cash flow information contained in the reserve information herein represent estimates only.
Petroleum engineers consider many factors and make assumptions in estimating reserves and resources.

Those factors and assumptions include:



| |  |  | historical production from the area compared with production rates from similar producing areas;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | the assumed effect of government regulation;
| | - |  | --------------------------------------------



| |  |  | assumptions about future commodity prices, exchange rates, production and development costs, capital expenditures, abandonment costs, environmental
liabilities, and applicable royalty regimes;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | initial production rates;
| | - |  | -------------------------



| |  |  | production decline rates;
| | - |  | -------------------------



| |  |  | ultimate recovery of reserves and resources;
| | - |  | --------------------------------------------



| |  |  | marketability of production; and
| | - |  | --------------------------------



| |  |  | other government levies that may be imposed over the producing life of reserves.
| | - |  | --------------------------------------------------------------------------------

If any of these factors and assumptions prove to be inaccurate, our actual results may vary materially from our reserve and resource estimates. Many of
these factors are subject to change and are beyond our control. In particular, changes in the prices of, and markets for, oil and natural gas from those anticipated at the time of making such assessments will affect the return on, and value of, our
Common Shares. In addition, all such assessments involve a measure of geological and engineering uncertainty that could result in lower production and reserves and resources than anticipated. A portion of our reserves are classified as
undeveloped and are subject to greater uncertainty than reserves classified as developed.

In accordance with normal
industry practices, we engage independent petroleum engineers to conduct a detailed engineering evaluation of our oil and gas properties for the purpose of estimating our reserves as part of our year end reporting process. As a result of that
evaluation, we may increase or decrease the estimates of our reserves. We do not consider an increase or decrease in the estimates of our reserves in the range of up to five percent to be material or inconsistent with normal industry practice. Any
significant reduction to the estimates of our reserves resulting from any such evaluation could have a material adverse effect on the value of our Common Shares.

If we are unable to acquire or develop additional reserves, the value of the Common Shares and dividends to our Shareholders may decline.

Oil and natural gas operations involve many risks that even a combination of experience, knowledge and careful evaluation may not be able to overcome. Our long-term commercial success depends on our
ability to find, acquire, develop and commercially produce oil and natural gas reserves. Without the continual addition of new reserves, our existing reserves, and the production from them, will decline over time as we produce from such reserves. A
future increase in our reserves will depend on both our ability to explore and develop our existing properties and on our ability to select and acquire suitable producing properties or prospects. There is no assurance that we will be able to
continue to find satisfactory properties to acquire or participate in. Moreover, our management may determine that current markets, terms of acquisition and, participation or pricing conditions make potential acquisitions or participations
uneconomic. There is also no assurance that we will discover or acquire further commercial quantities of oil and natural gas.

Future oil and
natural gas exploration may involve unprofitable efforts from dry wells as well as from wells that are productive but do not produce sufficient petroleum substances to return a profit after drilling, completing (including hydraulic fracturing),
operating and other costs. Completion of a well does not assure a profit on the investment or recovery of drilling, completion and operating costs.

Drilling hazards, environmental damage and various field operating conditions could greatly increase the cost of operations and adversely affect the production from successful wells. Field operating
conditions include, but are not limited to, delays in obtaining governmental approvals or consents, and shut-ins of connected wells resulting from extreme weather conditions, insufficient storage or transportation capacity or other geological and
mechanical conditions. While diligent well supervision and effective maintenance operations can contribute to maximizing production rates over time, it is not possible to eliminate production delays and declines from normal field operating
conditions, which can negatively affect revenue and cash flow levels to varying degrees.

Uncertainty in the credit markets may restrict the availability or increase the cost of borrowing
required for future development and acquisitions.

Uncertainty in domestic and international credit markets and other financial systems
could materially affect our ability to access sufficient capital for our capital expenditures and acquisitions and, as a result, may have a material adverse effect on our ability to execute our business strategy and on our financial condition. There
can be no assurance that financing will be available or sufficient to meet these requirements or for other corporate purposes or, if financing is available, that it will be on terms appropriate and acceptable to us. Should the lack of financing and
uncertainty in the capital markets adversely impact our ability to refinance debt, additional equity may be issued resulting in a dilutive effect on current and future Shareholders.

In the normal course of our business, we have entered into contractual arrangements with third parties that subject us to the risk that such parties may default on their obligations.

We are exposed to third party credit risk through our contractual arrangements with current or future joint venture partners, marketers of our petroleum
and natural gas production and other parties. In the event such entities fail to meet their contractual obligations to us, such failures could have a material adverse effect on our business, financial condition, results of operations and prospects.
In addition, poor credit conditions in the industry and of joint venture partners may impact a joint venture partners willingness to participate in our ongoing capital program, potentially delaying the program and the results of such program
until we find a suitable alternative partner.

We engage in hedging activities which could limit the full benefit of commodity price
increases.

From time to time we enter into agreements to receive fixed prices for our oil and natural gas production to offset the risk
of revenue losses if commodity prices decline. However, to the extent that we engage in price risk management activities to protect ourselves from commodity price declines, we may also be prevented from realizing the full benefits of price increases
above the levels of the derivative instruments used to manage price risk. In addition, our hedging arrangements may expose us to the risk of financial loss in certain circumstances, including instances in which:



| |  |  | production falls short of the hedged volumes;
| | - |  | ---------------------------------------------



| |  |  | there is a widening of price-basis differentials between delivery points for production and the delivery point assumed in the hedge arrangement;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the counterparties to the hedging arrangements or other price risk management contracts fail to perform under those arrangements; or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a sudden unexpected event materially impacts oil and natural gas prices.
| | - |  | ------------------------------------------------------------------------

Similarly, from time to time we may enter into agreements to fix the exchange rate of Canadian to United States dollars in order to offset the risk of revenue losses if the Canadian dollar increases in
value compared to the United States dollar. However, if the Canadian dollar declines in value compared to the United States dollar, we will not benefit from the fluctuating exchange rate.

Our operation of oil and natural gas wells could subject us to potential environmental claims and liabilities, which will be funded out of our cash flow and will reduce cash flow otherwise available
for dividend to Shareholders.

All phases of the oil and natural gas business present environmental risks and hazards and are subject to
environmental regulation pursuant to a variety of federal, provincial and local laws and regulations. Environmental legislation provides for, among other things, restrictions and prohibitions on spills, releases or emissions of various substances
produced in association with oil and natural gas operations. The legislation also requires that wells and facility sites be operated, maintained, abandoned and reclaimed to the satisfaction of applicable regulatory authorities.

Compliance with environmental legislation can require significant expenditures and a breach of applicable environmental legislation may result in the
imposition of fines and penalties, some of which may be material. Environmental legislation is evolving in a manner expected to result in stricter standards and enforcement, larger fines and liability and potentially increased capital expenditures
and operating costs. The discharge of oil, natural gas or other pollutants into the air, soil or water may give rise to liabilities to governments and third parties and may require us to incur costs to remedy such discharge. Although we believe that
we will be in material compliance with current applicable environmental regulations, no assurance can be given that environmental laws will not result in a curtailment of production or a material increase in the costs of production, development or
exploration activities or otherwise have a material adverse effect on our business, financial condition, results of operations and prospects.

##### Table of Contents

Our exploration and production facilities and other operations and activities emit greenhouse gases
which may require us to comply with greenhouse gas emissions legislation in Alberta and British Columbia or that may be enacted in other provinces.

Climate change policy is evolving at regional, national and international levels, and political and economic events may significantly affect the scope and timing of climate change measures that are
ultimately put in place. As a signatory to the United Nations Framework Convention on Climate Change (the UNFCCC) and as a participant to the Copenhagen Agreement (a non-binding agreement created by the UNFCCC), the
Government of Canada announced on January 29, 2010 that it will seek a 17% reduction in GHG emissions from 2005 levels by 2020. These GHG emission reduction targets are not binding, however. Although it is not the case today, some of our
significant facilities may ultimately be subject to future regional, provincial and/or federal climate change regulations to manage GHG emissions. The direct or indirect costs of compliance with these regulations may have a material adverse effect
on our business, financial condition, results of operations and prospects. Given the evolving nature of the debate related to climate change and the control of greenhouse gases and resulting requirements, it is not possible to predict the impact on
us and our operations and financial condition.

We may be unable to successfully compete with other industry participants, which could
negatively affect the market price of the Common Shares and dividends to our Shareholders.

The petroleum industry is competitive in all
its phases. We compete with numerous other entities in the search for, and the acquisition of, oil and natural gas properties and in the marketing of oil and natural gas. Our competitors include oil and natural gas companies that have substantially
greater financial resources, staff and facilities than us. Our ability to increase our reserves in the future will depend not only on our ability to explore and develop our present properties, but also on our ability to select and acquire other
suitable producing properties or prospects for exploratory drilling. Competitive factors in the distribution and marketing of oil and natural gas include price, methods, and reliability of delivery and storage.

The oil industry is characterized by rapid and significant technological advancements and introductions of new products and services utilizing new
technologies.

Other oil companies may have greater financial, technical and personnel resources that allow them to enjoy technological
advantages and may in the future allow them to implement new technologies before we can. There can be no assurance that we will be able to respond to such competitive pressures and implement such technologies on a timely basis or at an acceptable
cost. One or more of the technologies currently utilized by us or implemented in the future may become obsolete. In such case, our business, financial condition and results of operations could be materially adversely affected. If we are unable to
utilize the most advanced commercially available technology, our business, financial condition and results of operations could be materially adversely affected.

Fuel conservation measures, alternative fuel requirements, increasing consumer demand for alternatives to oil and natural gas, and technological advances in fuel economy and energy generation devices
could reduce the demand for oil and other liquid hydrocarbons.

We cannot predict the impact of changing demand for oil and natural gas
products, and any major changes may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Incorrect assessments of value at the time of acquisitions could adversely affect the value of our Common Shares and dividends to our Shareholders.

Acquisitions of oil and gas properties or companies are based in large part on engineering and economic assessments made by independent
engineers. These assessments include a series of assumptions regarding such factors as recoverability and marketability of oil and gas, future prices of oil and gas and operating costs, future capital expenditures and royalties and other government
levies which will be imposed over the producing life of the reserves. Many of these factors are subject to change and are beyond our control. All such assessments involve a measure of geologic and engineering uncertainty which could result in lower
than anticipated production and reserves.

Our indebtedness may limit the amount of dividends that we are able to pay our Shareholders, and
if we default on our debts, the net proceeds of any foreclosure sale would be allocated to the repayment of our lenders, note holders, Convertible Debenture holders and other creditors and only the remainder, if any, would be available for dividend
to our Shareholders.

We are indebted under our credit facility, the Convertible Debentures and the Notes. Certain covenants in the
agreements with our lenders and with respect to the Notes and the Convertible Debentures may limit the amount of dividends paid to Shareholders. Variations in interest rates, exchange rates and scheduled principal repayments could result in
significant changes in the amount we are required to apply to the service of our outstanding indebtedness. If we become unable to pay our debt service charges or otherwise cause an event of default to occur, our lenders may foreclose on, or sell,
our properties. The net proceeds of any such sale will be allocated firstly to the repayment of our lenders and other creditors and only the remainder, if any, would be payable to Shareholders. In addition, we may not be able to refinance some or
all of these debt obligations through the issuance of new debt obligations on the same terms, and we may be required to refinance through the issuance of new debt obligations on less favourable terms or through the issuance of additional securities
or through other means. In any such event, the amount of cash available for dividend may be diluted or adversely impacted and such dilution or impact may be significant.

##### Table of Contents

A decline in our ability to market our oil and natural gas production could have a material adverse
effect on production levels or on the price received for production, which, in turn, could reduce dividends to our Shareholders and affect the market price of the Common Shares.

The marketability of our production depends in part upon the availability, proximity and capacity of gas gathering systems, pipelines and processing and storage facilities. United States federal and state
and Canadian federal and provincial regulation of oil and gas production and transportation, general economic conditions, changes in supply and demand, market conditions and other conditions affecting infrastructure systems and facilities could
adversely affect our ability to produce and market oil and natural gas. If market factors dramatically change, the financial impact on us could be substantial. The availability of markets is beyond our control.

Although pipeline expansions are ongoing, the lack of firm pipeline capacity continues to affect the oil and natural gas industry and limit the ability
to produce and to market oil and natural gas production. In addition, the pro-rationing of capacity on inter-provincial pipeline systems also continues to affect the ability to export oil and natural gas. Any significant change in market factors or
other conditions affecting these infrastructure systems and facilities, as well as any delays in constructing new infrastructure systems and facilities could harm our business and, in turn, our financial condition.

Our financial performance also depends on revenues from the sale of commodities which differ in quality and location from underlying commodity prices
quoted on financial exchanges. Of particular importance are the price differentials between our light/medium oil, heavy oil (in particular the light/heavy differential) and bitumen and quoted market prices. Not only are these discounts influenced by
regional supply and demand factors, they are also influenced by other factors such as transportation costs, capacity and interruptions; refining demand; the availability and cost of diluent used to blend and transport product; and the quality of the
oil produced, all of which are beyond our control.

The operation of a portion of our properties is largely dependent on the ability of
third party operators, and harm to their business could cause delays and additional expenses in our receiving revenues, which could negatively affect the market price of the Common Shares and dividends to our Shareholders.

The continuing production from a property, and to some extent the marketing of production, is dependent upon the ability of the operators of our
properties. Approximately 37 percent of our properties are operated by third parties, based on daily production. If, in situations where we are not the operator, the operator fails to perform these functions properly or becomes insolvent, revenues
may be reduced. Revenues from production generally flow through the operator and, where we are not the operator; there is a risk of delay and additional expense in receiving such revenues.

The operation of the wells located on properties not operated by us are generally governed by operating agreements which typically require the operator to conduct operations in a good and workman-like
manner. Operating agreements generally provide, however, that the operator will have no liability to the other non-operating working interest owners for losses sustained or liabilities incurred, except such as may result from gross negligence or
wilful misconduct. In addition, third-party operators are generally not fiduciaries with respect to us or our Shareholders. As owner of working interests in properties not operated by us, we will generally have a cause of action for damages arising
from a breach of the operators duty. Although not established by definitive legal precedent, it is unlikely that we or our Shareholders would be entitled to bring suit against third party operators to enforce the terms of the operating
agreements. Therefore, our Shareholders will be dependent upon us, as owner of the working interest, to enforce such rights.

Our dividends
and the market price of the Common Shares could be adversely affected by unforeseen title defects, which could reduce dividends to our Shareholders.

Although title reviews may be conducted prior to the purchase of oil and natural gas producing properties or the commencement of drilling wells, such reviews do not guarantee or certify that an unforeseen
defect in the chain of title will not arise to defeat our claim. Our actual interest in properties may, therefore, vary from our records. If a title defect does exist, it is possible that we may lose all or a portion of the properties to which the
title defect relates, which may have a material adverse effect on our business, financial condition, results of operations and prospects. There may be valid challenges to title, or proposed legislative changes which affect title, to the oil and
natural gas properties we control that, if successful or made into law, could impair our activities on them and result in a reduction of the revenue received by us.

Fluctuations in foreign currency exchange rates and interest rates could adversely affect our business, the market price of the Common Shares and dividends to our Shareholders.

World oil and natural gas prices are quoted in United States dollars. The Canadian/United States dollar exchange rate fluctuates over time and as a
consequence affects the price received by Canadian producers of oil and natural gas. Recently, the Canadian dollar has increased materially in value against the United States dollar. Material increases in the value of the Canadian dollar negatively
affects our production revenues. Future Canadian/United States exchange rates could, accordingly, affect the future value of our reserves as determined by independent evaluators.

##### Table of Contents

To the extent that we engage in risk management activities related to foreign exchange rates, there is a
credit risk associated with counterparties with which we may contract.

An increase in interest rates could result in a significant increase
in the amount we pay to service debt, resulting in a reduced amount available to fund our exploration and development activities and, if applicable, the cash available for dividends and could negatively impact the market price of our Common Shares.

We may incur material costs as a result of compliance with health, safety and environmental laws and regulations which could negatively
affect our financial condition and, therefore, reduce dividends to our Shareholders and decrease the market price of the Common Shares.

Compliance with environmental laws and regulations could materially increase our costs. We may incur substantial capital and operating costs to comply
with increasingly complex laws and regulations covering the protection of the environment and human health and safety. In particular, we may be required to incur significant costs to comply with legislation and regulations to reduce emissions of
greenhouse gases into the air. See Industry Conditions.

Lower oil and gas prices increase the risk of write-downs of
our oil and gas property investments which could be viewed unfavourably in the market or could limit our ability to borrow funds or comply with covenants contained in our current or future credit agreements or other debt instruments.

Under Canadian accounting rules, the net capitalized cost of oil and gas properties may not exceed a ceiling limit which is based, in part,
upon estimated future net cash flows from reserves. If the net capitalized costs exceed this limit, we must charge the amount of the excess against earnings. As oil and gas prices and engineering price decks decline, our net capitalized cost may
approach and, in certain circumstances, exceed this cost ceiling, resulting in a charge against earnings. Under United States accounting rules, the cost ceiling is generally lower than under Canadian rules because the future net cash flows used in
the United States ceiling test are based on proven reserves only. Accordingly, we would have more risk of a ceiling test write-down in a declining price environment if we reported under United States generally accepted accounting principles. While
these write-downs would not affect cash flow, the charge to earnings could be viewed unfavourably in the market or could limit our ability to borrow funds or comply with covenants contained in our current or future credit agreements or other debt
instruments.

The ability of investors resident in the United States to enforce civil remedies may be negatively affected for a number of
reasons.

We are an Alberta corporation. We have our principal places of business in Canada. All of our directors and officers are
residents of Canada and all or a substantial portion of our assets and the assets of such persons are located outside of the United States. Consequently, it may be difficult for United States investors to affect service of process within the United
States upon us or such persons or to realize in the United States upon judgments of courts of the United States predicated upon civil remedies under the United States Securities Act of 1933, as amended. Investors should not assume that Canadian
courts:



| |  |  | will enforce judgments of United States courts obtained in actions against us or such persons predicated upon the civil liability provisions of the
United States federal securities laws or the securities or blue sky laws of any state within the United States; or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | will enforce, in original actions, liabilities against us or such persons predicated upon the United States federal securities laws or any such state
securities or blue sky laws.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Future acquisitions may result in substantial future dilution of your Common Shares.

One of our objectives is to continually add to our reserves through acquisitions and through development. Our success is, in part, dependent
on our ability to raise capital from time to time. Shareholders may also suffer dilution in connection with future issuances of Common Shares.

Canadian and United States practices differ in reporting reserves and production and our estimates may not be comparable to those of companies in the
United States.

We report our production and reserve quantities in accordance with Canadian practices and specifically in accordance with
NI 51-101. These practices are different from the practices used to report production and to estimate reserves in reports and other materials filed with the SEC by companies in the United States.

We incorporate additional information with respect to production and reserves which is either not required to be included or prohibited under rules of
the SEC and practices in the United States. We follow the Canadian practice of reporting gross production and reserve volumes; however, we also follow the United States practice of separately reporting these volumes on a net basis (after the
deduction of royalties and similar payments). We also follow the Canadian practice of using forecast prices and costs when we estimate our reserves. The SEC permits, but does not require, the disclosure of reserves based on forecast prices and
costs.

Reserve information contained herein may include estimates of proved, proved plus probable and possible
reserves, as well as resources. The SEC permits, but does not require, the inclusion of estimates of probable and possible reserves in filings made with it by United States oil and gas companies. The SEC does not permit the inclusion of estimates of
resources in reports filed with it by United States companies.

Changes in government regulations that affect the crude oil and natural gas
industry could adversely affect us and reduce our dividends to our Shareholders.

Various levels of governments impose extensive controls
and regulations on oil and natural gas operations (exploration, production, pricing, marketing and transportation). Governments may regulate or intervene with respect to exploration and production activities, prices, taxes and royalties. Amendments
to these controls and regulations may occur from time to time in response to economic or political conditions. The implementation of new regulations or the modification of existing regulations affecting the oil and natural gas industry could reduce
demand for crude oil and natural gas and increase our costs, either of which may have a material adverse effect on our business, financial condition, results of operations and prospects. In order to conduct oil and natural gas operations, we will
require licenses from various governmental authorities. There can be no assurance that we will be able to obtain all of the licenses and permits that may be required to conduct operations that it may wish to undertake. In addition to regulatory
requirements pertaining to the production, marketing and sale of oil and natural gas mentioned above, our business and financial condition could be influenced by federal legislation affecting, in particular, foreign investment, through legislation
such as the Competition Act (Canada) and the Investment Canada Act (Canada). See Industry Conditions.

Hydraulic Fracturing

Hydraulic
fracturing involves the injection of water, sand and small amounts of additives under pressure into rock formations to stimulate hydrocarbon (oil and natural gas) production. Specifically, hydraulic fracturing is used to produce commercial
quantities of oil and natural gas from reservoirs that were previously unproductive. Any new laws, regulations or permitting requirements regarding hydraulic fracturing could lead to operational delays, increased operating costs, third party or
governmental claims, and could increase our costs of compliance and doing business as well as delay the development of oil and natural gas resources from shale formations, which are not commercial without the use of hydraulic fracturing.
Restrictions on hydraulic fracturing could also reduce the amount of oil and natural gas that we are ultimately able to produce from our reserves.

We may become involved in, named a as a party to, or be the subject of, various legal proceedings including regulatory proceedings, tax proceedings and legal actions, related to personal injuries,
property damage, property tax, land rights, the environment and contract disputes.

The outcome of outstanding, pending or future
proceedings cannot be predicted with certainty and may be determined adversely to us and as a result, could have a material adverse effect on our assets, liabilities, business, financial condition and results of operations.

Aboriginal peoples have claimed aboriginal title and rights to portions of western Canada.

We are not aware that any claims have been made in respect of our properties and assets; however, if a claim arose and was successful such claim may have
a material adverse effect on our business, financial condition, results of operations and prospects.

We may disclose confidential
information relating to our business, operations or affairs while discussing potential business relationships or other transactions with third parties.

Although confidentiality agreements are signed by third parties prior to the disclosure of any confidential information, a breach could put us at competitive risk and may cause significant damage to our
business. The harm to our business from a breach of confidentiality cannot presently be quantified, but may be material and may not be compensable in damages. There is no assurance that, in the event of a breach of confidentiality, we will be able
to obtain equitable remedies, such as injunctive relief, from a court of competent jurisdiction in a timely manner, if at all, in order to prevent or mitigate any damage to its business that such a breach of confidentiality may cause.

We file all required income tax returns and we believe that we are in full compliance with the provisions of the Tax Act and all other applicable
provincial tax legislation.

However, such returns are subject to reassessment by the applicable taxation authority. In the event of a
successful reassessment of us, whether by re-characterization of exploration and development expenditures or otherwise, such reassessment may have an impact on current and future taxes payable.

##### Table of Contents

Income tax laws relating to the oil and gas industry, such as the treatment of resource taxation or
dividends, may in the future be changed or interpreted in a manner that adversely affects us. Furthermore, tax authorities having jurisdiction over us may disagree with how we calculate our income for tax purposes or could change administrative
practices to our detriment.

The level of activity in the Canadian oil and natural gas industry is influenced by seasonal weather
patterns.

Wet weather and spring thaw may make the ground unstable. Consequently, municipalities and provincial transportation
departments enforce road bans that restrict the movement of rigs and other heavy equipment, thereby reducing activity levels. Also, certain oil and natural gas producing areas are located in areas that are inaccessible other than during the winter
months because the ground surrounding the sites in these areas consists of swampy terrain. Seasonal factors and unexpected weather patterns may lead to declines in exploration and production activity and corresponding declines in the demand for our
goods and services as the demand for natural gas rises during cold winter months and hot summer months.

Terrorist attacks and the threat
of terrorist attacks may have an adverse impact on us.

Energy sector participants, including us, are a potential target for terrorists.
The possibility that infrastructure facilities may be direct targets of, or indirect casualties of, an act of terror and the implementation of security measures as a precaution against possible terrorist attacks may result in increased cost to our
business.

Delays in business operations could adversely affect dividends to Shareholders and the market price of the Common Shares.

In addition to the usual delays in payment by purchasers of oil and natural gas to the operators of our properties, and the delays of
those operators in remitting payment to us, payments between any of these parties may also be delayed by:



| |  |  | restrictions imposed by lenders;
| | - |  | --------------------------------



| |  |  | accounting delays;
| | - |  | ------------------



| |  |  | delays in the sale or delivery of products;
| | - |  | -------------------------------------------



| |  |  | delays in the connection of wells to a gathering system;
| | - |  | --------------------------------------------------------



| |  |  | blowouts or other accidents;
| | - |  | ----------------------------



| |  |  | adjustments for prior periods;
| | - |  | ------------------------------



| |  |  | recovery by the operator of expenses incurred in the operation of the properties; or
| | - |  | ------------------------------------------------------------------------------------



| |  |  | the establishment by the operator of reserves for these expenses.
| | - |  | -----------------------------------------------------------------

Any of these delays could reduce the amount of cash available for dividend to Shareholders in a given period and expose us to additional third party credit risks.

Changes in market-based factors may adversely affect the trading price of the Common Shares.

The market price of our Common Shares is sensitive to a variety of market based factors including, but not limited to, interest rates, foreign exchange
rates and the comparability of the Common Shares to other yield-oriented securities. Any changes in these market-based factors may adversely affect the trading price of the Common Shares.

The industry in which we operate exposes us to potential liabilities that may not be covered by insurance.

Oil and natural gas exploration, development and production operations are subject to all the risks and hazards typically associated with such operations, including, but not limited to, fire, explosion,
blowouts, sour gas releases and spills or other environmental hazards. These typical risks and hazards could result in substantial damage to oil and natural gas wells, production facilities, other property, the environment and personal injury.
Particularly, we may explore for and produce sour natural gas in certain areas. An unintentional leak of sour natural gas could result in personal injury, loss of life or damage to property and may necessitate an evacuation of populated areas, all
of which could result in liability to us.

Oil and natural gas production operations are also subject to all the risks typically associated
with such operations, including encountering unexpected formations or pressures, premature decline of reservoirs and the invasion of water into producing formations. Losses resulting from the occurrence of any of these risks may have a material
adverse effect on our business, financial condition, results of operations and prospects.

##### Table of Contents

As is standard industry practice, we are not fully insured against all of these risks, nor are all risks
insurable. Although we maintain liability insurance in an amount that we consider consistent with industry practice, liabilities associated with certain risks could exceed policy limits or not be covered. In either event we could incur significant
costs.

If there are delays in our projects, this may delay our expected revenues from operations.

We manage a variety of small and large projects in the conduct of our business. Project delays may delay expected revenues from operations. Significant
project cost over-runs could make a project uneconomic. Our ability to execute projects and market oil and natural gas depends upon numerous factors beyond our control, including:



| |  |  | the availability of processing capacity;
| | - |  | ----------------------------------------



| |  |  | the availability and proximity of pipeline capacity;
| | - |  | ----------------------------------------------------



| |  |  | the availability of storage capacity;
| | - |  | -------------------------------------



| |  |  | the supply of and demand for oil and natural gas;
| | - |  | -------------------------------------------------



| |  |  | the availability of alternative fuel sources;
| | - |  | ---------------------------------------------



| |  |  | the effects of inclement weather;
| | - |  | ---------------------------------



| |  |  | the availability of drilling and related equipment;
| | - |  | ---------------------------------------------------



| |  |  | unexpected cost increases;
| | - |  | --------------------------



| |  |  | accidental events;
| | - |  | ------------------



| |  |  | currency fluctuations;
| | - |  | ----------------------



| |  |  | changes in regulations;
| | - |  | -----------------------



| |  |  | the availability and productivity of skilled labour; and
| | - |  | --------------------------------------------------------



| |  |  | the regulation of the oil and natural gas industry by various levels of government and governmental agencies.
| | - |  | -------------------------------------------------------------------------------------------------------------

Because of these factors, we could be unable to execute projects on time, on budget or at all, and may be unable to market the oil and natural gas that
we produce effectively.

We may be subject to growth-related risks including capacity constraints and pressure on our internal systems and
controls.

Our ability to manage growth effectively will require us to continue to implement and improve our operational and financial
systems and to expand, train and manage our employee base. Our inability to deal with this growth may have a material adverse effect on our business, financial condition, results of operations and prospects.

Potential conflicts of interest.

Certain of our directors are also directors of other oil and gas companies and as such may, in certain circumstances, have a conflict of interest
requiring them to abstain from certain decisions. Conflicts, if any, will be subject to the procedures and remedies of the ABCA which require the director or officer who is a party to, or is a director or an officer of, or has a material interest in
any person who is a party to, a material contract or proposed material contract with us disclose his or her interest and, in the case of directors, to refrain from voting on any matter in respect of such contract unless otherwise permitted under the
ABCA.

Lindbergh Thermal Project Specific Risks

Our Lindbergh thermal project will require substantial capital investment over the coming years. In addition to the above, there are certain additional risk factors associated with the development of our
Lindbergh thermal project. These include the following:

Early Stage of Development

There is a risk that design and construction of the facilities and infrastructure to support our Lindbergh thermal project and any future commercial
projects will not be completed on time, on budget or at all. Additionally, there is a risk that the Lindbergh thermal project and any future commercial projects may have delays, interruptions of operations or increased costs due to many factors,
including, without limitation:

| |  |  | shortages of or delays in accessing drilling rigs and services.
| | - |  | ---------------------------------------------------------------

The Lindbergh thermal project is not being constructed on a turn-key basis. Additionally, given the state of development of the Lindbergh thermal project, various changes to the project may be made. Based
upon current scheduling, the project is not expected to start commercial SAGD operations until 2014 at the earliest. The information contained herein related to the Lindbergh thermal project, including, without limitation, reserve and economic
evaluations, assumes receipt of all regulatory approvals and no material changes being made to the project or its scope.

The industry is in a
period of substantial oil sands development and industrial activity. We will need to compete for equipment, supplies, services, and labour in this environment which could result in increased costs, shortages of goods and services that delay
progress, or both. Increased competition for equipment, materials and labour may result in increased costs that could have a material adverse effect on our business, financial condition or results of operations. As such, there are risks associated
with project cost estimates provided by us. Cost estimates are provided prior to pilot project results, completion of final scope design and detailed engineering needed to reduce the margin of error. Accordingly, actual costs may vary from estimates
and these differences may be material.

Operating Costs

The operating costs of the Lindbergh thermal project have the potential to vary considerably throughout the operating period and will be significant components of the cost of production of any petroleum
products produced by the Lindbergh thermal project. Project economics and our overall earnings may be reduced if increases in operating costs are incurred. Factors which could affect operating costs include, without limitation;



| |  |  | the amount and cost of labour to operate the Lindbergh thermal project;
| | - |  | -----------------------------------------------------------------------



| |  |  | the cost of catalyst and chemicals;
| | - |  | -----------------------------------



| |  |  | the actual steam oil ratio required to operate the SAGD well pairs;
| | - |  | -------------------------------------------------------------------

| | - |  | --------------------------



| |  |  | catastrophic events such as fires, earthquakes, storms or explosions.
| | - |  | ---------------------------------------------------------------------

Infrastructure for the Lindbergh Thermal Project

We will depend, to a large extent, on
third party designers, contractors and suppliers to design and construct the necessary facilities and infrastructure for the Lindbergh thermal project. We also anticipate that we will rely on certain infrastructure owned and operated or to be
constructed by others, including, without limitation, pipelines for the transportation of diluent and produced bitumen to the market, natural gas, water source and disposal pipelines and electrical grid transmission lines for the provision and/or
sale of electricity to us. The failure of any or all of these third parties to supply utilities, services or construct the infrastructure required to complete the Lindbergh thermal project on a timely basis and on acceptable commercial terms would
negatively impact our operation and financial results.

In-situ Extraction

Current SAGD technologies for in-situ recovery of heavy oil and bitumen are energy intensive, requiring significant consumption of natural gas and other fuels in the production of steam which is used in
the recovery process. The amount of steam required in the production process can also vary and significantly impact costs. The performance of the reservoir can also impact the timing and levels of production using this technology.

Recovery of Bitumen

Recovering bitumen
from oil sands involves particular risks and uncertainties. SAGD bitumen recovery facilities and development and expansion of production can entail significant capital outlays. SAGD projects like Lindbergh are susceptible to loss of production,
slowdowns, or restrictions on their ability to produce higher value products due to the interdependence of component systems. Severe weather conditions can cause reduced production and in some situations result in higher costs.

Access to Diluent Supplies at Favourable Prices

Bitumen is characterized by high specific gravity or weight and high viscosity or resistance to flow. Diluent, a hydrocarbon based diluting agent, is required to facilitate the transportation of bitumen.
A shortfall in the supply of diluent may cause its price to increase thereby increasing the cost to transport bitumen to market and correspondingly increasing our operating costs, decreasing our net revenues and negatively impacting the overall
profitability of the Lindbergh thermal project.

Marketing of Production

The market prices for heavy oil (which includes bitumen blends) are lower than the established market indices for light or medium grades of oil, due principally to diluent prices and the higher
transportation and refining costs associated with heavy oil. Also, the market for heavy oil is more limited than for light and medium grades of oil, making it more susceptible to supply and demand fundamentals. Future price differentials are
uncertain and any increase in heavy oil differentials could have an adverse effect on the anticipated returns from the Lindbergh thermal project as well as our overall business, financial condition, results of operations and cash flows.

##### Table of Contents

Audit-Related Fees

Audit-related fees normally include due diligence reviews in connection with acquisitions, research of accounting and audit-related issues and the completion of audits required by contracts to which we
are a party.

Tax Fees

During 2012 and 2011 the services provided in this category included assistance and advice in relation to the preparation of income tax returns for us and
our subsidiaries, tax advice and planning and commodity tax consultation.

Pre-approval Policies and Procedures

Pengrowth has adopted the following policies and procedures with respect to the pre-approval of audit and permitted non-audit services to be provided by
KPMG LLP. The Audit and Risk Committee approves a schedule which summarizes the services to be provided that the Audit and Risk Committee believes to be typical, recurring or otherwise likely to be provided by KPMG LLP. The schedule generally covers
the period between the adoption of the schedule and the end of the year, but at the option of the Audit and Risk Committee, may cover a shorter or longer period. The list of services is sufficiently detailed as to the particular services to be
provided to ensure that (i) the Audit and Risk Committee knows precisely what services it is being asked to pre-approve and (ii) it is not necessary for any member of Pengrowths management to make a judgment as to whether a proposed
service fits within the pre-approved services. Services that arise that were not contemplated in the schedule must be pre-approved by the Audit and Risk Committee chairman or a delegate of the Audit and Risk Committee. The full Audit and Risk
Committee is informed of the services at its next meeting.

Pengrowth has not approved any non-audit services on the basis of the de
minimis exemptions. All non-audit services are pre-approved by the Audit and Risk Committee in accordance with the pre-approval policy referenced herein.

CONFLICTS OF INTEREST

Our Board of Directors supervises our
management of our business and affairs. The Board of Directors approves significant strategic operational decisions and all decisions relating to:



| |  |  | the issuance of additional Common Shares;
| | - |  | -----------------------------------------



| |  |  | material acquisitions and dispositions of properties;
| | - |  | -----------------------------------------------------



| |  |  | material capital expenditures;
| | - |  | ------------------------------



| |  |  | borrowing; and
| | - |  | --------------



| |  |  | the payment of dividends.
| | - |  | -------------------------

Circumstances may arise where members of our Board of Directors serve as directors or officers of corporations which are in competition to our interests.
The Board of Directors reviews potential conflicts of interest at each meeting. No assurances can be given that opportunities identified by such board members will be provided us. In addition, some members of our senior management team sit as
directors of other corporations. Any such positions must be disclosed to the Board of Directors and approved by the Chief Executive Officer.

LEGAL PROCEEDINGS

We are sometimes named as a defendant in
litigation. The nature of these claims is usually related to settlement of normal operational or labour issues. The outcome of such claims against us are not determinable at this time, however they are not expected to have a materially adverse
effect on us as a whole. We are not, and have not been at any time within the most recently completed financial year, a party to any legal proceedings, known or contemplated, where the damages involved, excluding interest and costs, exceed ten
percent of our assets.

CODE OF ETHICS

Pengrowth has adopted a
code of ethics, as that term is defined in Form 40-F under the US Securities Exchange Act of 1934(the Code of Ethics) that applies to Pengrowths management, including its Chief Executive Officer, Chief Financial
Officer and principal accounting officer. The Code of Ethics is available for viewing on our website www.pengrowth.com under the name Code of Business Conduct , and is available in print to any Shareholder who requests it.

##### Table of Contents

OFF-BALANCE SHEET ARRANGEMENTS

Pengrowth has no off-balance

DISCLOSURE PURSUANT TO THE REQUIREMENTS

OF THE NEW YORK STOCK EXCHANGE

As a Canadian reporting issuer with securities listed on the TSX, Pengrowth has in place a system of corporate governance practices which complies with Canadian securities laws and the TSX corporate
governance guidelines as well as the corporate governance rules of the NYSE applicable to foreign private issuers. In the context of its listing on the New York Stock Exchange, Pengrowth is classified as a foreign private issuer and therefore only
certain of the NYSE rules are applicable to Pengrowth. However, Pengrowth benchmarks its policies and procedures against major North American entities, with a view to adopting the best practices when appropriate to its circumstances.

The Board of Directors of the Corporation has adopted and published a Corporate Governance Policy which affirms Pengrowths commitment to
maintaining a high standard of corporate governance. This policy is published on Pengrowths website at www.pengrowth.com. The Board of Directors of the Corporation has also adopted Terms of Reference for each of an Audit and Risk Committee, a
Corporate Governance and Nominating Committee, a Compensation Committee, and a Reserves, Health, Safety and Environment Committee, a Code of Business Conduct and Ethics, a Corporate Disclosure Policy and an Insider Trading Policy each of which is
published on Pengrowths website, and is available in print to any Shareholder who requests it. The Audit and Risk Committees Terms of Reference are attached hereto as Appendix C. From time to time, special committees of the Board of
Directors are formed with prescribed mandates.

There is only one significant way in which Pengrowths corporate governance practices
differ from those required to be followed by domestic United States issuers under the NYSE Listed Company Manual. The NYSE Listed Company Manual requires shareholder approval of all equity compensation plans and any material revisions to such plans,
regardless of whether the securities to be delivered under such plans are newly issued or purchased on the open market, subject to a few limited exceptions. In contrast, the TSX rules require shareholder approval of equity compensation plans only
when such plans involve newly issued securities. Additionally, if an equity compensation plan provides a procedure for its amendment, the TSX rules require shareholder approval of amendments only where the amendment involves a reduction in the
exercise price or an extension of the term of options held by insiders.

ADDITIONAL INFORMATION

Additional information, including directors and officers remuneration, the principal holders of Common Shares and securities
authorized for issuance under equity compensation plans, is contained in our Management Information Circular which relates to the Annual Meeting of Shareholders to be held on June 25, 2013. Additional financial information is contained in our
comparative consolidated financial statements and associated managements discussion and analysis for the years ended December 31, 2012, 2011 and 2010.

Additional information relating to us may be found on SEDAR at www.sedar.com and on EDGAR at the SECs website at www.sec.gov.

General Commentary to Section 303A.02(b):

An immediate family member includes a persons spouse, parents, children, siblings, mothers and fathers-in-law, sons and daughters-in-law, brothers and sisters-in-law, and anyone (other
than domestic employees) who shares such persons home. When applying the look-back provisions in Section 303A.02(b), listed companies need not consider individuals who are no longer immediate family members as a result of legal separation
or divorce, or those who have died or become incapacitated.

##### Table of Contents

MANAGEMENTS DISCUSSION & ANALYSIS The following Managements Discussion and Analysis (MD&A) of financial results should be read in conjunction with the audited Consolidated Financial Statements for the year ended December 31, 2012 of Pengrowth Energy Corporation. This MD&A is based on
information available to February 28, 2013. Pengrowths fourth quarter and annual results for 2012 are contained within this MD&A. BUSINESS OF THE CORPORATION Pengrowth
Energy Corporation (Pengrowth or the Corporation) is a Canadian resource company that is engaged in the production, development, exploration and acquisition of oil and natural gas assets. This MD&A contains the results of Pengrowth and seven months of results from its subsidiary, NAL Energy Corporation (NAL) which was acquired by Pengrowth on May 31, 2012 and which was amalgamated with Pengrowth on January 1, 2013. FREQUENTLY RECURRING TERMS Pengrowth uses the following frequently recurring industry terms in this
MD&A: bbls refers to barrels,
bbl/d refers to barrels per day,
Mbbls refers to thousands of barrels,
boe refers to barrels of oil equivalent, boe/d refers to barrels of oil equivalent per day, Mboe refers to thousand boe, MMboe refers to million boe, Mcf refers to thousand
cubic feet, Mcf/d refers to thousand cubic feet per day, MMcf refers to million cubic feet, Bcf refers to billion cubic feet, MMBtu refers to million British thermal units,
MMBtu/d refers to million British thermal units per day, MW refers to megawatt and MWh refers to megawatt hour. Disclosure provided herein in respect of a boe
may be misleading, particularly if used in isolation. A boe conversion ratio of six Mcf of natural gas to one barrel of crude oil equivalent is based on an energy equivalency conversion method primarily applicable at the burner tip and does not
represent a value equivalency at the wellhead. ADVISORY REGARDING FORWARD-LOOKING STATEMENTS This MD&A contains forward-looking statements within the meaning of securities laws, including the safe harbour provisions of Canadian securities
legislation and the United StatesPrivate Securities Litigation Reform Act of 1995. Forward-looking information is often, but not always, identified by the use of words such as anticipate, believe, expect,
plan, intend, forecast, target, project, guidance, may, will, should, could, estimate, predict or similar
words suggesting future outcomes or language suggesting an outlook. Forward-looking statements in this MD&A include, but are not limited to, statements with respect to: reserves, production, the proportion of production of each product type,
production additions from Pengrowths development program, royalty expenses, operating expenses, deferred income taxes, goodwill, asset retirement obligations, taxability of dividends, remediation, reclamation and abandonment expenses, capital
expenditures, development activities, general and administration expenses, and proceeds from the disposal of properties. Statements relating to reserves are forward-looking statements, as they involve the implied assessment, based on
certain estimates and assumptions that the reserves described exist in the quantities predicted or estimated and can profitably be produced in the future. Forward-looking statements and information are based on Pengrowths current beliefs as well as assumptions made by, and information currently available to, Pengrowth concerning general economic and financial
market conditions, anticipated financial performance, business prospects, strategies, regulatory developments, including in respect of taxation, royalty rates and environmental protection, future capital expenditures and the timing thereof, future
oil and natural gas commodity prices and differentials between light, medium and heavy oil prices, future oil and natural gas production levels, future exchange rates and interest rates, the proceeds of anticipated divestitures, the amount of future
cash dividends paid by Pengrowth, the cost of expanding our property holdings, our ability to obtain labour and equipment in a timely manner to carry out development activities, our ability to market our oil and natural gas successfully to current
and new customers including transportation availability, the impact of increasing competition, our ability to obtain financing on acceptable terms, our ability to add production and reserves through our development, exploitation and exploration
activities, our ability to complete divestments to generate cash to repay debt and fund capital projects. Although management considers these assumptions to be reasonable based on information currently available to it, they may prove to be
incorrect. By their very nature, forward-looking statements involve inherent risks and uncertainties, both general and specific, and risks that
predictions, forecasts, projections and other forward-looking statements will not be achieved. We caution readers not to place undue reliance on these statements as a number of important factors could cause the actual results to differ materially
from the beliefs, plans, objectives, expectations and anticipations, estimates and intentions expressed in such forward-looking statements.

##### Table of Contents

These factors include, but are not limited to: the volatility of oil and gas prices; production and development costs and capital expenditures; the imprecision of reserve estimates and estimates
of recoverable quantities of oil, natural gas and liquids; Pengrowths ability to replace and expand oil and gas reserves, ability to produce those reserves; production may be impacted by unforeseen events such as equipment and transportation
failures and weather related issues; environmental claims and liabilities; incorrect assessments of value when making acquisitions; increases in debt service charges; the loss of key personnel; the marketability of production; defaults by third
party operators; unforeseen title defects; fluctuations in foreign currency and exchange rates; inadequate insurance coverage; counterparty risk; compliance with environmental laws and regulations; changes in tax and royalty laws; Pengrowths
ability to access external sources of debt and equity capital; the implementation of International Financial Reporting Standards (IFRS); and
the implementation of greenhouse gas emissions legislation. Further information regarding these factors may be found under the heading Business Risks herein and under Risk Factors in Pengrowths most recent Annual
Information Form (AIF), and in Pengrowths most recent audited Consolidated Financial Statements, management information circular,
quarterly reports, material change reports and news releases. Copies of Pengrowths Canadian public filings are available on SEDAR at www.sedar.com. Pengrowths U.S. public filings, including the most recent annual report form 40-F
as supplemented by its filings on form 6-K, are available at www.sec.gov. Pengrowth cautions that the foregoing list of factors that may affect
future results is not exhaustive. When relying on our forward-looking statements to make decisions with respect to Pengrowth, investors and others should carefully consider the foregoing factors and other uncertainties and potential events.
Furthermore, the forward-looking statements contained in this MD&A are made as of the date of this MD&A and Pengrowth does not undertake any obligation to update publicly or to revise any of the included forward-looking statements, except as
required by law. The forward-looking statements in this document are provided for the limited purpose of enabling current and potential investors to evaluate an investment in Pengrowth. Readers are cautioned that such statements may not be
appropriate, and should not be used for other purposes. The forward-looking statements contained in this MD&A are expressly qualified by this
cautionary statement. CRITICAL ACCOUNTING ESTIMATES The audited Consolidated Financial Statements are prepared in accordance with IFRS. Management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of
the Consolidated Financial Statements and revenues and expenses for the period ended. Certain of these estimates may change from period to period resulting in a material impact on Pengrowths results of operations, financial position, and
change in financial position. Estimating oil and gas reserves Pengrowth engages a qualified, independent oil and gas reserves evaluator to perform an estimation of the Corporations oil and gas reserves at least annually. Reserves form the basis for the calculation of
depletion charges and assessment of impairment of oil and gas assets. Reserves are estimated using the reserve definitions and guidelines prescribed by National Instrument 51-101 (NI
51-101) and the Canadian Oil and Gas Evaluation Handbook (COGEH). Proved plus probable reserves are defined as the best estimate of quantities of oil, natural gas and related substances estimated to be commercially
recoverable from known accumulations, from a given date forward, based on drilling, geological, geophysical and engineering data, the use of established technology and specified economic conditions. It is equally likely that the actual remaining
quantities recovered will be greater than or less than the sum of the estimated proved plus probable reserves. The estimates are made using all available geological and reservoir data as well as historical production data. Estimates are reviewed and
revised as appropriate. Revisions occur as a result of changes in prices, costs, fiscal regimes and reservoir performance or a change in Pengrowths plans with respect to future development or operating practices. Determination of Cash Generating Units (CGUs) CGUs are the smallest group of assets that generate cash inflows largely independent from other assets or group of assets. Determination of what constitutes a CGU
is subject to managements judgment. The asset composition of a CGU can directly impact the recoverability of the assets included therein. The recoverability of development and production asset carrying values are assessed at the CGU level. In
assessing the recoverability of oil and gas properties, each CGUs carrying value is compared to its recoverable amount, defined as the greater of fair value less costs to sell and value in use. Asset Retirement Obligation Pengrowth estimates obligations
under environmental regulations in respect of decommissioning and site restoration. These obligations are determined based on the expected present value of expenses required in the process of plugging and abandoning wells, dismantling of wellheads,
production and transportation facilities and restoration of producing areas in accordance with relevant legislation, discounted from the date when expenses are expected to be incurred. Most of the abandonment of Pengrowths

wells is estimated to take place far in the future. Therefore, changes in estimated timing of future expenses, estimated logistics of performing abandonment work and the discount rate used to
present value future expenses could have a significant effect on the carrying amount of the decommissioning provision. Impairment testing Impairment testing of property, plant and equipment is completed for each of Pengrowths CGUs. Impairment testing is based primarily on
estimates of proved plus probable reserves, production rates, oil and natural gas prices, future costs, discount rates and other relevant assumptions including undeveloped land and contingent resources. The impairment assessment of goodwill is based
on the estimated fair value of Pengrowths CGUs. By their nature, these estimates are subject to measurement uncertainty and may impact the financial statements of future periods. Valuation of trade and other receivables, and prepayments to suppliers Management estimates the likelihood of
the collection of trade and other receivables and recovery of prepayments based on an analysis of individual accounts. Factors taken into consideration include the aging of receivables in comparison with the credit terms allowed to customers and the
financial position and collection history with the customer. Should actual collections be less than estimates, Pengrowth would be required to record an additional expense. NAL Acquisition In connection with the NAL Acquisition completed on May 31, 2012, fair values assigned to
the various assets and liabilities of NAL were based on internal and third party estimates. COMPARATIVE FIGURES Certain changes to the presentation of transportation costs by product type were made in 2012 and, as such, comparative periods have been restated with no impact to
net income. In 2012, the MD&A disclosures for the capital expenditures are presented net of capitalized stock based compensation as presented on the Consolidated Statements of Cash Flow. Management believes that these presentation changes better
reflect Pengrowths operating results. As required under IFRS, changes in the accounting for the NAL Acquisition that arose in the fourth quarter of 2012 were adjusted retrospective to the second quarter of 2012. ADDITIONAL GAAP MEASURE Funds Flow from
Operations Pengrowth uses Funds Flow from Operations, a Generally Accepted Accounting Principles (GAAP) measure that is not defined under IFRS. Management believes that in addition to cash provided by operations, Funds Flow from Operations, as reported in
the Consolidated Statements of Cash Flow is a useful supplemental measure as it provides an indication of the funds generated by Pengrowths principal business activities prior to consideration of changes in working capital and remediation
expenditures. Pengrowth considers this to be a key measure of performance as it demonstrates its ability to generate cash flow necessary to fund dividends and capital investments. NON-GAAP FINANCIAL MEASURES This MD&A refers to certain financial measures that are not
determined in accordance with IFRS. These measures do not have standardized meanings and may not be comparable to similar measures presented by other oil and gas companies. Measures such as operating netbacks do not have standardized meanings
prescribed by GAAP. See the section of this MD&A entitled Operating Netbacks for a discussion of the calculation. The current level of capital
expenditures funded through retained cash flow, as compared to debt or equity, can be determined when it is compared to the difference in Funds Flow from Operations and dividends paid as shown on the Consolidated Statements of Cash Flow. Management monitors Pengrowths capital structure using non-GAAP financial metrics. The two metrics are Total Debt to the trailing twelve months Earnings
Before Interest, Taxes, Depletion, Depreciation, Amortization, Accretion, and other non-cash items (Adjusted EBITDA) and Total Debt to Total
Capitalization. Total Debt is the sum of working capital and long term debt including convertible debentures as shown on the Consolidated Balance Sheets, and Total Capitalization is the sum of Total Debt and Shareholders Equity. Payout Ratio is a term used to evaluate financial flexibility and the capacity to fund dividends. Payout Ratio is defined on a percentage basis as dividends
declared divided by Funds Flow from Operations. Management believes that, in addition to net income (loss), Adjusted Net Income (Loss) is a useful supplemental measure as it reflects the underlying performance of Pengrowths business activities
by excluding the after tax effect of non-cash commodity mark to market gains and losses, non-cash

mark to market gains and losses on investments, gains on acquisitions (negative goodwill) and unrealized foreign exchange gains and losses that may significantly impact net income (loss) from
period to period. Management believes that segregating General and Administrative (G&A) expenses into cash and non-cash expenses is
useful to the reader, as non-cash expenses only affect net income (loss) but not Funds Flow from Operations. OPERATIONAL MEASURES The reserves and production in this MD&A refer to company-interest reserves or production that is Pengrowths working interest share of
production or reserves prior to the deduction of Crown and other royalties plus any Pengrowth-owned royalty interest in production or reserves at the wellhead, in accordance with Canadian industry practice. Company-interest is more fully described
in the AIF. When converting natural gas to equivalent barrels of oil within this MD&A, Pengrowth uses the industry standard of six Mcf to one boe.
Barrels of oil equivalent may be misleading, particularly if used in isolation; a conversion ratio of six Mcf of natural gas to one boe is based on an energy equivalency conversion and does not represent a value equivalency at the wellhead. Pengrowths ability to grow both reserves and production can be measured with the following metrics: Reserves per share, reserves per debt
adjusted share, production per share and production per debt adjusted share. Reserves per share and reserves per debt adjusted share are measured using year end proved plus probable reserves and the number of common shares outstanding at year end.
The reserves per debt adjusted share is debt adjusted by assuming additional shares are issued at year end share prices to replace year end long term debt outstanding. Production per share and production per debt adjusted share are measured in respect of the average production for the year and the weighted average number of common shares outstanding during the year. The
production per debt adjusted share is debt-adjusted by assuming additional shares are issued at year end share prices to replace year end long term debt outstanding. Recycle ratio is a measure of value creation for each dollar spent. This measure is calculated as operating netback per boe divided by Finding and Development
(F&D) cost per boe and can also be calculated using Finding, Development & Acquisition (FD&A) cost per boe. Recycle ratio can be calculated including or excluding Future Development Capital
(FDC). CURRENCY All amounts are stated in Canadian dollars unless otherwise specified. 2012 AND 2013 GUIDANCE AND 2012 FINANCIAL HIGHLIGHTS The following table provides a summary of the

Starting in 2013, Pengrowth will reclassify approximately $20 million relating primarily to technical support costs to G&A from operating expenses. Full year and fourth quarter production were at the low end of Guidance primarily due to the ongoing outage at Sable Offshore Energy
Project (SOEP) and third party pipeline capacity and sales restrictions at Pine Creek. The impact of the SOEP outage was 640 boe/d for the
full year 2012 and 1,850 boe/d for the fourth quarter 2012. Royalty expense was lower than Guidance primarily due to the impact of lower NAL royalty
rates, an increase in Gas Cost Allowance (GCA) credits and lower commodity prices. Operating expenses were essentially on target with Guidance.

##### Table of Contents

G&A expenses were lower than Guidance due to additional NAL production with little incremental G&A added. Capital expenditures amounted to $467.4 million in 2012 which was below the $525.0 million Guidance as Pengrowth moderated spending in a weak commodity
price environment. Production and related operating and other expenses from the Lindbergh pilot are excluded from these items in the table above.
Pengrowth included production revenue and costs associated with the Lindbergh pilot project in capital expenditures prior to project sanctioning in January 2013. See Note 7 to the audited Consolidated Financial Statements for additional information.
Pengrowth will record revenue, operating and other expenses from Lindbergh in its results, starting in 2013. FINANCIAL HIGHLIGHTS  Three months ended

) The 34 percent increase in Funds Flow from Operations in the fourth quarter compared to the third quarter of 2012, was primarily
due to higher natural gas prices in the quarter, increased oil production and commodity risk management gains, as well as lower operating expenses. Higher natural gas revenue, net of volume and risk management impacts, contributed $20.2 million to
the Funds Flow from Operations when comparing the fourth quarter to the third quarter of 2012.

##### Table of Contents

The 11 percent increase in Funds Flow from Operations in the fourth quarter compared to the fourth quarter of
2011, was primarily due to higher production volumes as a result of the NAL Acquisition partly offset by significantly lower average realized prices and higher operating costs. Higher discounts of the Canadian light oil versus WTI benchmark during
the fourth quarter had an unfavourable financial impact on oil sales of approximately $14 million compared to the same period last year. The 13 percent
decrease in Funds Flow from Operations for the full year of 2012 compared to 2011, was primarily due to significantly lower average realized prices and higher operating and other expenses, partly offset by higher oil and natural gas production
volumes from the NAL Acquisition. Other expenses for 2012 included approximately $22 million in one-time NAL Acquisition costs. Higher discounts of the Canadian light oil versus WTI benchmark during 2012 had an unfavourable financial impact on oil
sales of approximately $93 million compared to 2011. Net Income (Loss) Pengrowth recorded a net loss of $1.1 million in the fourth quarter compared to a net loss of $23.7 million in the third quarter of 2012, representing a $22.6 million improvement. The decrease in net loss was
primarily driven by the increase in Funds Flow from Operations and lower unrealized losses on commodity risk management partly offset by higher unrealized foreign exchange losses and an unrealized loss on an investment. The fourth quarter net loss decreased by $7.9 million from a net loss of $9.0 million in the same period last year. The change was also driven by the increase in
Funds Flow from Operations and a lower unrealized loss on commodity risk management partly offset by increases in Depletion, Depreciation and Amortization (DD&A) coupled with unrealized foreign exchange and investment losses. For the full year 2012, Pengrowth recorded
net income of $12.7 million compared to net income of $84.5 million for 2011. The $71.8 million decrease in net income was primarily driven by higher DD&A and impairment charges, a decrease in Funds Flow from Operations partly offset by a gain
on commodity risk management, a gain on acquisition and a tax recovery. Adjusted Net Income (Loss) The following table provides a reconciliation of net income (loss) to Adjusted Net Income (Loss):  Three months ended

2012



(89.7
) Pengrowth recorded Adjusted Net Income of $24.1 million in the fourth quarter of 2012 compared to an Adjusted Net Loss of $18.7
million in the prior quarter. This change was driven by the positive impact of an increase in Funds Flow from Operations and a deferred tax adjustment, partly offset by slightly higher DD&A and an absence of the prior quarter gain on
disposition. In comparison to the same period last year, Pengrowth recorded an increase in Adjusted Net Income of $1.8 million in the fourth quarter of
2012. An increase in Funds Flow from Operations, a deferred tax adjustment and the absence of impairment charges in the current quarter, partly offset by the increase in DD&A were the primary reasons for the change. For the full year 2012, Pengrowth recorded an Adjusted Net Loss of $89.7 million compared to Adjusted Net Income of $110.9 million in 2011. The decrease in Funds
Flow from Operations coupled with increases in DD&A and impairment charges were the primary drivers of the year over year change. Price

131.2 million Pengrowth common shares to former NAL shareholders, as well as the assumption by Pengrowth of NALs convertible debentures and long term debt. The TSX closing share price of Pengrowth on the acquisition date of May 31,
2012, was $7.36 per share.

evaluation. The deferred tax liability was determined based on applying Pengrowths effective deferred income tax rate of approximately 25 percent to the difference between the book and tax basis of the net assets acquired. The asset retirement
obligation was determined using Pengrowths estimated timing and costs to remediate, reclaim and abandon the wells and facilities. An inflation rate of 2 percent and a discount rate of 8 percent were used. As part of finalizing of certain
balances Pengrowth decreased the previously recorded working capital deficiency by $5.7 million resulting in an adjustment to the gain on acquisition which will be reflected in the second quarter of 2012 comparative quarterly figures. The gain on acquisition amounted to $73.5 million and is recorded as a separate line item on the Consolidated Statements of Income. This gain has no basis for tax
purposes. RESULTS OF OPERATIONS (All volumes,
wells and spending amounts stated below reflect Pengrowths net working interest unless otherwise stated.) CAPITAL EXPENDITURES For the full year 2012, Pengrowth spent $467.4 million on capital expenditures excluding property acquisitions and dispositions. Approximately 79
percent of capital expenditures were invested in drilling, completions and facilities, with the remaining 21 percent spent on land, seismic, maintenance and other capital.  Three months ended

Pengrowth included production revenue and costs associated with the Lindbergh pilot
project in capital expenditures until the first phase of the project was sanctioned in January 2013. Focus Areas (Pengrowth references average well test results for certain properties. These results are not necessarily representative of long term well performance or ultimate
recoveries.) Swan Hills Trend With a net
estimated 2.3 billion barrels of 42° API original oil in place in the Beaverhill Lake formation (Energy Resources Conservation Board estimate), the Swan Hills Trend is a significant conventional oil resource for Pengrowth. This extensive
carbonate oil reservoir provides Pengrowth with significant opportunities to put its expertise in horizontal drilling and multi-stage acid fracturing of carbonate reservoirs to work on its operated interests in Judy Creek, Carson Creek, Deer
Mountain, Virginia Hills and Sawn Lake. During the fourth quarter, Pengrowth drilled 3 operated wells (3.0 net) in the Swan Hills area (2 oil wells and
1 produced water injector), and participated in the drilling of 3 non-operated oil wells (0.5 net). During 2012, Pengrowth spent $170.7 million on
development activities targeting light oil and liquids-rich opportunities at Judy Creek, Carson Creek, Deer Mountain and Virginia Hills. Pengrowth drilled a total of 24 operated wells (22.7 net), primarily targeting the tighter platform and R5
shoal. In addition, 12 partner-operated oil wells (2.5 net) were drilled targeting the House Mountain, Freeman and Sawn Lake plays. Greater
Olds/Garrington Area Pengrowth holds a large, contiguous land base in the greater Olds/Garrington area of over 500 gross sections of Cardium rights,
extensive infrastructure and significant operatorship.

Activity in the Cardium continued in the fourth quarter with 2 operated (1.3 net) wells being drilled at Lochend.
Both wells were completed and brought on production in January 2013. Non operated Cardium drilling accounted for 7 (1.2 net) wells during the fourth quarter of 2012 all of which are expected to be on production in the first quarter of 2013. During the fourth quarter, Pengrowth acquired additional assets in the Lochend area to complement the large position associated with the NAL
Acquisition adding approximately 530 boe/d with more optimization of this production expected in early 2013. This acquisition also added 32 net drilling locations. In total, Pengrowth has identified more than 80 drillable locations (55 net) in the
Lochend area. Pengrowth also increased its natural gas handling capacity at the Lochend battery with additional compression being added which has significantly reduced incineration in the area. In the fourth quarter, Pengrowth continued with the liquids-rich gas program in the Elkton formation, drilling 1 operated (0.9 net) well for which completion and
testing was done before year end with the final tie-in expected in early January 2013. The five day average IP rate for this well was approximately 250 boe/d of liquids rich natural gas. Full year 2012, Pengrowth spent $94.8 million on development activities in the greater Olds/Garrington area, participating in the drilling of 41 wells (19.0 net). Lindbergh The Lindbergh property, located in the Cold Lake
area of Alberta and encompassing 42.5 gross sections of land, is 100 percent owned and operated by Pengrowth. The Lindbergh thermal project targets the Lloydminster formation, where the bitumen has better flow characteristics and oil quality, which
will translate into higher netbacks than originally anticipated. Based on very positive pilot project results during 2012, an initial 12,500 bbl/d commercial development was sanctioned by the Board of Directors in January 2013 and will be
constructed during 2013 and 2014. The engineering phase of the 12,500 bbl/d project is ongoing, with capital investment in critical path and long lead items being completed. Subject to permitting, field construction is slated to begin by mid 2013
with drilling activities to commence in the fourth quarter of 2013. Lindbergh is expected to provide Pengrowth with the potential to develop production of up to 50,000 bbl/d of bitumen over three phases of development. This is expected to be low
operating and sustaining capital cost, low decline, stable oil production, with a twenty-five year reserve life. Pengrowth drilled 6 (6.0 net) core
holes at Lindbergh in the fourth quarter with results as anticipated. The wells were drilled in support of the commercial application currently being compiled for the second phase which will increase the facility to 30,000 bbl/d. The application is
anticipated to be submitted by the end of 2013. 2013 Capital Program Pengrowth anticipates a 2013 capital program, excluding acquisitions, of $770 million. This is a 65 percent increase from 2012 capital expenditures of $467.4 million and is focused on both thermal and conventional
programs. Pengrowths $470 million conventional capital program is focused on oil and liquids rich plays at Swan Hills and the greater Olds/Garrington area, while the thermal capital program of $300 million is focused on the Lindbergh 12,500
bbl/d project. RESERVES AND PERFORMANCE MEASURES Reserves  Company Interest at Forecast Prices  Reserves Summary (MMboe except as noted)

##### Table of Contents

Pengrowth reported year end Proved Reserves of 300.1 MMboe and Total Proved plus Probable reserves of 512.0 MMboe
for 2012, representing increases of 28 percent and 55 percent, respectively, from year end 2011. During 2012, Pengrowths development and optimization activities as well as the sanctioning of the Lindbergh thermal project resulted in the
addition of 21.0 MMboe of Proved Reserves and 103.8 MMboe of Total Proved plus Probable Reserves including revisions. The NAL Acquisition along with some strategic asset acquisitions in 2012, offset by minor dispositions, resulted in overall
increases of 75.9 MMboe in Proved Reserves and 109.4 MMboe in Total Proved Plus Probable Reserves. The reserve additions in 2012 resulted in a reserve replacement ratio of 327 percent for Total Proved Plus Probable Reserves excluding net
acquisitions, and 672 percent including net acquisitions. Further details of Pengrowths 2012 year end reserves, Finding and Development
(F&D) and Finding, Development & Acquisition (FD&A) calculations are provided in the AIF which is filed on SEDAR (www.sedar.com) or the 40-F filed on Edgar (www.sec.gov). Performance Measures  Finding & Development Costs & Recycle Ratio

Recycle Ratio is calculated as operating netback per boe divided by FD&A costs per boe based on proved plus probable reserves. The 2012 total proved plus probable F&D cost, including changes in Future Development Capital (FDC), was $16.85/boe, a 16 percent decrease from the 2011 F&D cost. The decrease from 2011 is primarily due to the addition of 88.8 MMboe for the Lindbergh thermal project. Recycle ratio is an important performance measure in assessing investment profitability and provides a comparison to our competitors. Pengrowths operating
results and capital program in 2012 yielded a recycle ratio, excluding net acquisitions and including changes in FDC, of 1.4 on a proved plus probable basis, in line with the three year average of 1.5. Despite an improvement in the F&D
cost, the recycle ratio remained unchanged from 2011 as the netback was negatively impacted by lower realized oil prices and depressed natural gas prices.  Other Performance Measures

##### Table of Contents

Pengrowths goal over longer periods is to modestly grow production and reserves per debt adjusted share,
while continuing to pay a prudent dividend. On a debt adjusted basis, production and total proved plus probable reserves per share decreased in 2012, primarily due to the reduction in Pengrowths share price used to value the debt at
December 31, 2012. However, overall production growth was 16 percent and the reserve replacement ratio was 327 percent for the year which positively impacted reserves per share. PRODUCTION  Three months ended

73,973 The above table includes seven months of NAL production and excludes production from the Lindbergh thermal project. Fourth quarter average daily production remained relatively unchanged when compared to the prior quarter. The incremental production from new drills and from the
November acquisition of assets at Lochend was partially offset by an ongoing outage at SOEP, where the Venture offshore platforms remained shut-in for the entire fourth quarter reducing production by 1,850 boe/d. The addition of the NAL production
is the primary driver of the 23 percent increase when comparing fourth quarter production to the same period last year and was in part offset by the SOEP operational outage and natural declines. Full year average daily production increased 16
percent when compared to 2011 and was positively impacted by both the addition of NAL volumes and production from new wells at Lochend and Judy Creek, partially offset by the 640 boe/d production loss from the SOEP outage, and by natural declines. Light Oil Fourth quarter light oil average
daily production increased 3 percent compared to the third quarter. The increase can be primarily attributed to the Lochend property acquisition and new wells drilled in the area. A 39 percent increase in light oil production in the current quarter
compared to the same period in 2011 was due to added NAL production, while a 31 percent increase year over year is primarily due to added NAL production and production from the development program. Heavy Oil Heavy oil production, excluding Lindbergh,
remained virtually unchanged in the fourth quarter compared to the third quarter as optimization efforts offset natural declines. Heavy oil volumes increased by 1 percent for the current quarter and the full year of 2012 compared to the same periods
in 2011, as additional production and optimization efforts more than offset natural declines. NGLs NGL production increased 8 percent in the fourth quarter compared to the prior quarter due to a condensate shipment at SOEP as well as added production from new
liquids-rich gas wells at Harmattan. Fourth quarter NGL production and full year production both increased 11 percent compared to the same periods last year, driven by additional NAL production but partly offset by the outage at SOEP and declines at
Carson Creek. Natural Gas Natural gas
production for the fourth quarter decreased 4 percent compared to the third quarter due to the extended outage at SOEP, capacity and sales restrictions at Pine Creek, as well as freeze-ups in several properties due to cold weather in December.
Natural gas production increased 19 percent from the same quarter last year as the positive impact of the NAL Acquisition was partially offset by the extended outage at SOEP and natural declines. The 11 percent increase in natural gas production for
the full year of 2012 compared to 2011 was also predominantly influenced by added production from the NAL Acquisition, partially offset by the SOEP outage, the Olds gas plant turnaround in the second quarter and the shut-in of dry gas production due
to low natural gas prices during 2012. As natural gas prices improved during the fourth quarter, approximately 500 boe/d of previously shut-in gas
production has been brought back on stream. Approximately 500 boe/d of dry natural gas still remained shut-in for the fourth quarter of 2012.

Prior periods restated to conform to presentation in the current period. WTI benchmark average oil prices decreased 9 percent to Cdn$87.36/bbl in the fourth quarter of 2012 from an average price of
Cdn$95.98/bbl in the fourth quarter of 2011, while the Canadian benchmark Edmonton par average light oil prices declined 14 percent compared to an average price of Cdn$97.91/bbl during the same period last year. For the full year, WTI averaged
Cdn$94.15/bbl in 2012, essentially unchanged from the same period in 2011. The price/bbl differential between Canadian light oil and WTI narrowed
substantially in the fourth quarter compared to wider discounts throughout much of 2012. Canadian light oil traded at an average discount of Cdn$2.77/bbl to WTI in the fourth quarter, compared to a premium of Cdn$1.93/bbl in the same period of 2011.
Full year, Canadian light oil prices traded at an average discount of Cdn$7.86/bbl to WTI in 2012, compared to a premium of Cdn$1.19/bbl to WTI in 2011. Pipeline constraints into the major U.S. refining hubs and increased light oil production from
the U.S. Bakken fields were the primary reasons for the substantial discount. We expect the differentials to remain volatile until the pipeline constraints are resolved. Pengrowths average realized price for light oil, after risk management activities, was $85.82/bbl in the fourth quarter, a decline of 6 percent from the fourth quarter of 2011. Full year 2012, light oil
realized prices averaged $83.58/bbl, a 7 percent decline from the same period in 2011. Contributing to the lower realized prices in 2012 was the decline in Canadian benchmark light oil prices, primarily a result of the widening differential between
Canadian light oil and the benchmark WTI oil prices, offset by gains from Pengrowths risk management activities. Pengrowths average
realized prices for heavy oil and natural gas liquids were down 18 and 20 percent, respectively, in the fourth quarter compared to the fourth quarter of 2011. Full year, prices declined 6 and 16 percent, respectively, primarily due to lower
benchmark Canadian light oil pricing and widening price differentials to WTI benchmark prices. Natural Gas Prices  Three months ended

resulted in record storage volumes of natural gas and weak prices.

##### Table of Contents

AECO spot gas price was $3.19/MMBtu in the fourth quarter as it continued to trade at a discount to the NYMEX gas
benchmark with the differential averaging $0.31/MMBtu. This compares to $2.30/MMBtu in the third quarter and $3.19/MMBtu in the same period last year. The full year 2012 AECO spot price was $2.38/MMBtu which was down 34 percent from full year 2011.
Higher transportation costs to major delivery points in the U.S. and an increase in domestic U.S. natural gas production, resulted in decreased demand and contributed to the lower pricing of Canadian natural gas. Pengrowths average realized natural gas price, after risk management activities, was $3.14/Mcf during the fourth quarter of 2012, a 31 percent increase from
the third quarter price of $2.40/Mcf, and a 17 percent decline compared to the fourth quarter of 2011 average price of $3.77/Mcf. Full year 2012, average realized natural gas prices were $2.49/Mcf, a 39 percent decline compared to an average price
of $4.08/Mcf in the same period of 2011. Pengrowths lower average realized prices in 2012 were attributable to a lower benchmark price for
natural gas when compared to the same periods in 2011, coupled with a lower contribution from realized natural gas commodity risk management activities, as lower volumes were under risk management and at a lower average price. Total Average Realized Prices  Three months ended

result of lower Canadian benchmark prices for oil and liquids due to the substantial discounting of Canadian light oil versus the WTI benchmark oil prices, decreased Canadian natural gas prices as well as lower natural gas volumes being under risk
management. Commodity Risk Management Gains (Losses)  Three months ended

##### Table of Contents

Pengrowth has an active risk management program which primarily uses forward price swaps to manage the exposure
to commodity price fluctuations and provide a measure of stability to cash flow. During the second quarter of 2012, Pengrowth also acquired swaps, options and collars with the NAL Acquisition. Fourth quarter realized gains from oil risk management increased $9.5 million compared to the prior quarter as Pengrowths average fixed risk management
contracted price exceeded the benchmark oil prices more than it had in the prior quarter. For the full year 2012 Pengrowth recorded a $9.9 million realized gain, compared to a $20.4 million loss in 2011, as the average fixed risk management
contracted price exceeded the benchmark oil prices in 2012, contrary to the same period last year. Realized gains from natural gas commodity risk
management activities decreased 56 percent in the fourth quarter compared to the third quarter, due to narrowing of the gap between the benchmark prices relative to the risk management contracted prices in the current quarter. Realized risk
management gains were also reduced by 67 percent for the full year of 2012 compared to 2011 due to decreased natural gas volumes under risk management and decreased risk management contracted prices. This resulted in narrowing of the gap between the
benchmark natural gas price and Pengrowths average natural gas risk management contracted prices in 2012 and consequently resulting in lower realized risk management gains in 2012. The change in fair value of the forward contracts between periods affects net income (loss) through the unrealized amounts recorded during the period. The fair value of forward contracts is determined by comparing
the risk management contracted fixed price to the forward price curve at each period end. The value of the options in place is confirmed with external agencies at period end. Pengrowth recognized a $0.5 million unrealized loss in the fourth quarter
compared to a $45.4 million unrealized loss in the third quarter of 2012. The primary reason for the lower unrealized loss in the current quarter is a reduction in the WTI forward curve. The $30.6 million unrealized gain for the full year compared
to a $39.9 loss in 2011 is due to a decrease in the forward price curve relative to Pengrowths risk management contracted fixed price. Unrealized gains (losses) vary period to period, and are a function of the volumes under risk management
contracts, the fixed prices of those risk management contracts and the forward curve pricing for the commodities under risk management contracts. Unrealized losses result when the forward price curve moves higher than the fixed price, with the
magnitude of the loss being proportional to the movement in the forward price curve. Forward Contracts The following table provides a summary of the minimum prices of our commodity risk management contracts in place at December 31, 2012 (see Note 18 to the

##### Table of Contents

Pengrowth has entered into additional commodity risk management contracts subsequent to December 31, 2012 for the
years 2013, 2014 and 2015. See Note 23 to the audited Consolidated Financial Statements for details. For 2013, Pengrowth now has 65% of its oil production under risk management at $93.81/bbl. At December 31, 2012, each Cdn$1/bbl change in future WTI oil prices results in approximately $6.5 million pre-tax change in the value of the crude risk management contracts, while each Cdn$0.25/MMBtu change
in future natural gas prices results in approximately $17.3 million pre-tax change in the value of the natural gas risk management contracts. The changes in the fair value of the forward risk management contracts directly affect reported net income
(loss) through the unrealized amounts recorded in the Consolidated Statements of Income during the period. The effect on cash flow will be recognized separately only upon settlement of the risk management contracts, which could vary significantly
from the unrealized amount recorded due to timing and prices when each contract is settled. If each commodity risk management contract were to have
settled at the risk management contract price in effect at December 31, 2012, future revenue and cash flow would have been $7.0 million higher than if the risk management contracts were not in place based on the estimated fair value of the risk
management assets at period end. The $7.0 million is composed of net assets of $5.9 million relating to risk management contracts expiring within one year and net assets of $1.1 million relating to risk management contracts expiring beyond one year. Each Cdn$1/MWh change in future power prices would result in approximately $0.1 million pre-tax change in the fair value of the risk management
contracts. Pengrowth has not designated any outstanding commodity risk management contracts as hedges for accounting purposes and therefore records
these risk management contracts on the Consolidated Balance Sheets at their fair value and recognizes changes in fair value on the Consolidated Statements of Income as unrealized commodity risk management gains (losses). The volatility in net income
(loss) will continue to the extent that the fair value of commodity risk management contracts fluctuates. However, these non-cash amounts do not affect Pengrowths operating cash flow until realized. Realized commodity risk management gains (losses) are recorded in oil and gas sales on the Consolidated Statements of Income and impact cash flow at that time. In accordance with policies approved by its Board of Directors, Pengrowth may sell forward its production and purchase risk management option contracts
by product volume or power consumption as follows:  Percent of Monthly Company Interest Production or Estimated Power Consumption

Primarily sulphur sales. Light oil sales
increased 31 percent in the fourth quarter compared to the same period in 2011, primarily due to increased production as a result of the NAL Acquisition, partly offset by a 15 percent realized price decline. Natural gas sales remained relatively
unchanged as a decrease in commodity risk management gains and a 6 percent price decline were offset by sales from increased production. Natural gas liquids sales decreased by 11 percent primarily impacted by a 20 percent decrease in prices partly
offset by an 11 percent increase in production volumes, while heavy oil sales decreased 17 percent due to price declines. Higher discounts of the
Canadian light oil versus WTI benchmark during the fourth quarter had an unfavourable financial impact on oil sales of approximately $14 million compared to the same period last year. Full year 2012 versus 2011 The following table illustrates the effect of changes in prices and volumes on the

19.3 Royalties include Crown, freehold, overriding royalties and mineral taxes. Royalty payments are based on sales before commodity
risk management activities; however, gains or losses from realized commodity risk management activities are reported as part of sales and therefore affect royalty rates as a percentage of sales. Royalty rates, as a percentage of sales excluding realized risk management activities, decreased from 17.7 percent in the third quarter of 2012 to 16.8 percent in
the current quarter. This was due to several factors including higher gross overriding and other income recorded in the quarter, which is not subject to royalties, and an increase in royalty relief and credits including GCA. Royalty rates, as a percentage of sales excluding risk management, decreased from 18.7 percent in the fourth quarter of 2011 to 16.8 percent in the current
quarter. The primary reason for the decrease is the added impact of NAL royalty rates which have historically been lower than Pengrowths due to a higher weighting of freehold royalties which are generally lower than Crown royalties. Increases
in GCA and gross overriding income have also contributed to the royalty rate decrease. On a year over year basis royalty rates, as a percentage of
sales excluding the impact of realized risk management contracts, decreased from 19.3 percent in 2011 to 19 percent in 2012. The decrease is primarily driven by the impact of lower NAL royalty rates and commodity price declines. 2013 royalty rates, as a percentage of sales, are forecast to be 17 percent.

14.15 Operating expenses in the fourth quarter decreased $10.9 million or $1.21 on a per boe basis compared to the third quarter due to
reduced maintenance, turnaround and chemical costs, partially offset by slightly higher power costs. Fourth quarter operating expenses increased $21.5
million or 22 percent compared to the same period last year primarily due to the additional NAL operating costs associated with a 23 percent production increase. On a per boe basis, operating expenses decreased $0.12/boe to $14.01/boe. For the full year of 2012 compared to 2011, operating expenses increased by $76.6 million or 20 percent. The increase is primarily attributable to an increase in
production volumes of 16 percent related to NAL and additional costs from the Olds turnaround during the second quarter of 2012. On a per boe basis, operating expenses increased $0.46/boe to $14.61/boe. 2013 operating expenses are forecast to be $14.00 to $14.50 per boe. Starting in 2013, Pengrowth will reclassify approximately $20 million relating primarily to
technical support costs to G&A from operating expenses. TRANSPORTATION COSTS  Three months ended

##### Table of Contents

In the fourth quarter of 2012, total transportation costs increased 14 percent compared to the third quarter and
16 percent compared to the fourth quarter of 2011, due to delays in pipeline connections and new production at Lochend. Year over year transportation
costs decreased 4 percent due to lower clean oil transportation costs as 2011 costs were negatively affected by the Rainbow Pipeline interruption from May to September of 2011. Pengrowth incurs transportation costs for its natural gas production once the product enters a pipeline at a title transfer point. Pengrowth has the option to sell some of its natural gas directly to markets
outside of Alberta by incurring additional transportation costs. Pengrowth sells most of its natural gas without incurring significant additional transportation costs. Pengrowth also incurs transportation costs on its oil and NGL production that
includes clean oil trucking charges and pipeline costs up to the custody transfer point. Pengrowth has elected to sell approximately 55 percent of its crude oil at market points beyond the wellhead incurring transportation costs to the first major
trading point. The transportation cost is dependent upon third party rates and distance the product travels on the pipeline prior to changing ownership or custody. OPERATING NETBACKS Pengrowths operating netbacks have been calculated by taking balances
directly from the Consolidated Statements of Income and dividing by production. Certain assumptions have been made in allocating operating expenses, other income and royalty injection credits between light oil, heavy oil, natural gas and NGL
production. Operating netbacks as presented below may not be comparable to similar measures presented by other companies, as there are no standardized measures. The sales price used in the calculation of operating netbacks is after realized
commodity risk management gains (losses).  Three months ended

##### Table of Contents

Pengrowth realized an average operating netback of $27.09/boe in the fourth quarter, a 26 percent increase
compared to the third quarter of 2012, primarily due to higher oil and gas sales and lower operating expenses. For the full year of 2012, Pengrowth realized an average operating netback of $22.93/boe, compared to $28.45/boe in 2011. The 19 percent
decrease is primarily caused by lower average realized prices. The natural gas netback for the fourth quarter was $1.07/Mcf compared to $0.24/Mcf in
the prior quarter due to a 31 percent increase in the realized natural gas price, including risk management, in the fourth quarter. The natural gas netback declined significantly for the full year of 2012 compared to 2011. This was due to a 39
percent decline in the average realized natural gas price, including risk management, year over year. Pengrowth also shut-in approximately 1,000 boe/d of primarily dry natural gas production during the second and third quarters, and approximately
500 boe/d during the fourth quarter. Pengrowths natural gas netbacks should be viewed in conjunction with the NGLs netbacks, which were
$28.29/bbl in the fourth quarter and $27.75/bbl for the full year of 2012, since virtually all of our current active natural gas production yields NGLs. GENERAL AND ADMINISTRATIVE EXPENSES  Three months ended

2.79 Fourth quarter cash G&A expenses were $2.5 million and $1.8 million higher compared to the prior quarter and the fourth quarter
of 2011, respectively. Both increases were primarily due to added personnel costs from the NAL Acquisition and increased professional services. On a per boe basis, however, cash G&A has decreased to $2.09/boe in the fourth quarter compared to
$2.31/boe in the same period last year. For the full year of 2012, cash G&A per boe also decreased to $2.12/boe from $2.38/boe in 2011. As anticipated, this decrease reflects the benefit of the increased production resulting from the NAL
Acquisition. The non-cash component of G&A represents the compensation expense associated with Pengrowths Long Term Incentive Plans
(LTIP). See Note 14 to the audited Consolidated Financial Statements for additional information. The compensation costs associated with these
plans are expensed over the applicable vesting period. Non-cash G&A expense decreased $2.4 million in the fourth quarter compared to the third quarter primarily due to a lower performance multiplier on previously expensed grants. The higher
non-cash G&A expenses in 2012 compared to the prior year were primarily due to additional grants issued in 2012. 2013 G&A expenses are expected
to be $3.30/boe including non-cash G&A of approximately $0.46/boe. Starting in 2013, Pengrowth will reclassify approximately $20 million relating primarily to technical support costs to G&A from operating expenses. OTHER EXPENSES For the full year of 2012, other
expenses of $27.6 million included approximately $22 million in one time transaction costs related to the NAL Acquisition. GAIN (LOSS)
ON INVESTMENTS Pengrowth owns 1.0 million shares of a private corporation with an estimated fair value of $20.0 million at December 31, 2012
compared to $35.0 million at December 31, 2011. The fair value of these shares has decreased since December 31, 2011 resulting in an unrealized loss of $15.0 million compared to an unrealized gain of $23.0 million recognized in 2011. See
Note 5 to the audited Consolidated Financial Statements for additional information. DEPLETION, DEPRECIATION, AMORTIZATION AND ACCRETION  Three months ended

##### Table of Contents

The 2 percent increase in depletion expense in the fourth quarter of 2012 compared to the third quarter of 2012
was primarily due to an increase in the Unit of Production (UOP) rate from higher capital spending on property acquisitions. Comparing the
fourth quarter and the full year of 2012 to the same periods last year, depletion increased 40 percent and 30 percent, respectively, primarily due to additional depletion recorded on property, plant and equipment from the NAL Acquisition. Accretion expense also increased in the fourth quarter and full year 2012 due to the ARO increase from the NAL Acquisition. IMPAIRMENTS Impairment tests were performed at
December 31, 2011, June 30, 2012 and December 31, 2012. The recoverable amounts of each CGU were based on the higher of value in use or fair value less costs to sell. Based on the impairment tests carried out, there were no
impairments at December 31, 2012, but impairments were recorded at June 30, 2012 and December 31, 2011. The impairment test is sensitive to lower commodity prices, which have been under significant downward pressure in recent periods,
particularly natural gas prices. Further declines in commodity prices in 2013 could result in additional impairment charges as the cushions in the CGU impairment tests have been eroded by price decreases. At June 30, 2012, Pengrowth tested its predominantly natural gas CGUs for impairments as a result of declining forward price estimates for natural gas. Of the
CGUs tested, only one was impaired. Pengrowth recognized a $30 million pre-tax impairment charge on the producing portion of the Groundbirch CGU, as the carrying value exceeded the fair value at June 30, 2012. Fair value was determined based on
the total proved plus probable reserves, estimated by Pengrowths independent reserves evaluator, using the July 1, 2012 commodity price forecast of Pengrowths independent reserves evaluator discounted at a market rate. See Note 6 to
the audited Consolidated Financial Statements for additional information. At June 30, 2012, Pengrowth also recognized a $48.3 million pre-tax
impairment of the Horn River Exploration and Evaluation (E&E) assets. It was determined that there would be no additional capital
spending at Horn River, which will result in the expiry of the majority of Pengrowths existing leases in the area. As a result, the carrying value of the Horn River E&E assets was written down to nil at June 30, 2012. See Note 7 to
the audited Consolidated Financial Statements for additional information. At December 31, 2011, Pengrowth recognized a $27.4 million pre-tax
impairment charge on the producing portion of the Groundbirch CGU as the carrying value exceeded the fair value on December 31, 2011. Fair value was determined based on the total proved plus probable reserves estimated by Pengrowths
independent reserves evaluator using the period end commodity price forecast of Pengrowths independent reserves evaluator and discounted at a market rate. This impairment charge resulted from a low natural gas price forecast by
Pengrowths independent reserves evaluator and allocation of 2012 capital to properties with better economic returns. As a result, goodwill attributed to the Groundbirch CGU was reduced by $16.3 million to nil and the PP&E was reduced by
$11.1 million. See Note 6 to the audited Consolidated Financial Statements for detailed disclosure of the assumptions used to determine the fair value. INTEREST AND FINANCING CHARGES  Three months ended

75.9 At December 31, 2012, Pengrowth had approximately $1.8 billion in total debt, composed of $1.6 billion in long term debt and
$0.2 billion in convertible debentures. Total debt consists primarily of U.S. dollar denominated fixed rate notes at a weighted average interest rate of 5.7 percent, drawings from Pengrowths syndicated bank facility which is subject to
prevailing market rates, and convertible debentures with a 6.25 percent coupon. At December 31, 2012, the bank facility and the demand operating facility cost of funds was approximately 3 percent. On October 18, 2012 Pengrowth issued $385
million U.S. equivalent of senior unsecured term notes, proceeds of which were used to pay down Pengrowths current credit facilities. Interest
and financing charges were $2.1 million or 9 percent higher in the fourth quarter compared to the third quarter primarily due to interest expense on the newly issued term notes which replaced shorter term bank debt. Comparing the fourth quarter to
the same period last year, interest and financing charges increased $4.6 million or 22 percent. This increase is due to convertible debentures assumed with the NAL Acquisition and additional interest on the newly issued term notes. The convertible
debentures contributed $3.4 million of net interest expense to interest and financing charges in the fourth quarter compared to the same quarter last year. The $10.5 million or 14 percent increase in interest expense and financing charges year over year reflects the higher debt levels outstanding in the current year, particularly the increased expense of $8.3 million
relating to the convertible debentures assumed with the NAL Acquisition.

##### Table of Contents

Pengrowth has various floating to fixed interest rate swap contracts which were acquired with NAL. Under these
contracts, Pengrowth pays a fixed rate and receives a floating rate, the Canadian three months Bankers Acceptance CDOR (Canadian Depository Offered Rate), on the notional amounts. The fair value of the interest rate derivative contracts has been included on the Consolidated Balance Sheets with changes in the fair value reported separately on the Consolidated
Statements of Income as part of interest and financing charges. See Note 18 to the audited Consolidated Financial Statements for additional information. TAXES Deferred income tax is a non-cash item relating to temporary differences between the accounting
and tax basis of Pengrowths assets and liabilities and has no immediate impact on Pengrowths cash flows. Pengrowth recorded a deferred tax reduction of $32.0 million during the year ended December 31, 2012 compared to a deferred tax
expense of $22.3 million during the year ended December 31, 2011. The decrease in deferred income tax expense primarily relates to the decrease in pre-tax income from 2011 to 2012. Also contributing to the decrease in 2012 is the recognition of
previously uncertain tax benefits. No current income taxes were paid by Pengrowth in 2012 or 2011. See Note 12 to the audited Consolidated Financial
Statements for additional information. FOREIGN CURRENCY GAINS (LOSSES)  Three months ended

(1.6
) Pengrowths unrealized foreign exchange gains and losses are primarily attributable to the translation of the foreign
denominated long term debt. The gains or losses are calculated by comparing the translated Canadian dollar balance of foreign denominated long term debt from one period to another. In the fourth quarter Pengrowth recorded an unrealized foreign
exchange loss of $16.2 million compared to gains of $32.2 million and $31.6 million in the prior quarter and the fourth quarter of 2011, respectively, primarily as a result of a weaker Canadian dollar relative to the U.S. dollar and U.K. Pound. The
additional U.S. term debt issued in October contributed $3.3 million to the unrealized foreign exchange loss in the current quarter. In contrast,
Pengrowth recorded a $14.0 million unrealized foreign exchange gain for the full year of 2012 compared to a $20.9 million loss for 2011 primarily due to a stronger Canadian dollar at year end relative to the U.S. dollar on December 31, 2011. Pengrowth acquired various foreign exchange contracts with the NAL Acquisition. The swaps and various types of options require Pengrowth to sell the
notional U.S. dollar monthly amount pursuant to the terms of each contract. See Note 18 to the audited Consolidated Financial Statements for additional information. Pengrowth does not use hedge accounting for any foreign exchange risk management
contracts. During 2012, a series of swap contracts were transacted in order to fix the foreign exchange rate on a portion of Pengrowths U.S.
dollar denominated term debt. Each swap requires Pengrowth to buy U.S. dollars at a predetermined rate and time, based upon maturity dates of the U.S. dollar term debt. The fair value of foreign exchange derivative contracts has been included on the
Consolidated Balance Sheets with changes in the fair value reported on the Consolidated Statements of Income as an unrealized foreign exchange (gain) loss.

U.K. Pound Sterling note issuances outstanding. The first was issued in 2005 and the second in 2012. The exchange rate is fixed at approximately $0.4976 and $0.63 U.K. Pound Sterling per Canadian dollar, respectively. ASSET RETIREMENT OBLIGATIONS (ARO)  ($ millions)

2012 amount relates to the change in the discount rate from 8 percent to 2.5 percent
on the ARO balances assumed in the business combinations. 2011 amount relates to reductions in the risk free rate during the year. The offset to the revisions is recorded in property, plant and equipment. The total future ARO is based on managements estimate of costs to remediate, reclaim and abandon wells and facilities having regard for Pengrowths
working interest and the estimated timing of the costs to be incurred in future periods. Pengrowth has developed an internal process to calculate these estimates which considers applicable regulations, actual and anticipated costs, type and size of
well or facility and the geographic location. For the year ended December 31, 2012, Pengrowths ARO liability increased by $208.0 million
mainly due to the additional ARO liabilities assumed in the NAL Acquisition, and the associated impact of the discount rate reduction. Pengrowth has
estimated the net present value of its total ARO to be $868.9 million as at December 31, 2012 (December 31, 2011  $660.9 million), based on a total escalated future liability of $2.4 billion (December 31, 2011  $1.8 billion). These
costs are expected to be incurred over 65 years with the majority of the costs incurred between 2036 and 2077. A risk free discount rate of 2.5 percent per annum and an inflation rate of 1.5 percent were used to calculate the net present value of
the ARO. REMEDIATION TRUST FUNDS AND REMEDIATION AND ABANDONMENT EXPENSE During 2012, Pengrowths contributions were $6.3 million (December 31, 2011  $7.1 million), into trust funds established to fund certain abandonment and reclamation costs associated with Judy Creek and
SOEP. The total balance of the remediation trust funds was $53.8 million at December 31, 2012 (December 31, 2011  $49.7 million). As a
working interest holder in SOEP, Pengrowth is under a contractual obligation to contribute to a remediation trust fund. The funding levels are based on the raw production delivered and processed at the various facilities. Funding levels for this
fund may change each year pending a review by the owners. Pengrowth takes a proactive approach to managing its well abandonment and site restoration
obligations. There is an on-going program to abandon wells and reclaim well and facility sites. Through December 31, 2012, Pengrowth spent $27.6 million on

abandonment and reclamation (December 31, 2011  $21.9 million). Pengrowth expects to spend approximately $21 million in 2013 on reclamation and abandonment, excluding contributions to
remediation trust funds and orphan well levies from the Alberta Energy Resources Conservation Board. CLIMATE CHANGE PROGRAMS Since becoming effective July 1, 2007, Alberta regulates Greenhouse Gas (GHG) emissions under the Climate Change and Emissions Management Act. Under the Act the Specified Gas Reporting Regulation (the SGRR) imposes annual GHG emissions reporting requirements on all Alberta facilities that emit more than 50,000 tonnes of greenhouse gases per year. Also under the Act, the Specified Gas Emitters Regulation (the
SGER) requires Alberta facilities that emit more than 100,000 tonnes of greenhouse gases per year to reduce emissions intensity by 12 percent
annually over baseline emission levels for those facilities. The baseline for facilities is an average of 2003, 2004 and 2005 emissions. Facilities can meet these required reductions in three ways: audited emission reductions in their operations;
purchased Alberta-based offset carbon credits or; contributions to the Alberta Climate Change and Emissions Management Fund. Unutilized reduction credits from one year may be carried forward to future years. During 2012, Pengrowth submitted GHG information on two facilities, the Olds Gas Plant and the Judy Creek Gas Conservation Plant, which had reduced emissions by
approximately 42 percent during 2011, well ahead of the 12 percent annual reduction target. During 2012, Pengrowth also acquired additional interest in the Quirk Creek Gas Plant and became the operator of that facility. Quirk Creek is a Specified
Gas Emitter facility therefore Pengrowth now has three operated facilities that are subject to the annual 12 percent reduction and will be reporting emission reduction information on the three facilities in 2013. For further information on Greenhouse Gas emissions, see Pengrowths AIF. GOODWILL In accordance with IFRS, goodwill is tested for impairment at each year end, or when there
is an indication of impairment, in conjunction with the assessment of impairment of property, plant and equipment. Management has assessed the goodwill and determined that there is no impairment at December 31, 2012. As at December 31,
2012, Pengrowth has goodwill of $700.7 million which was unchanged from December 31, 2011.See Note 8 to the audited Consolidated Financial
Statements for details. ACQUISITIONS AND DISPOSITIONS In the fourth quarter Pengrowth acquired properties in the Lochend area for $61.4 million and disposed of its Kakwa property and a portion of its Dawson area property for proceeds of $9.1 million. During the fourth
quarter, Pengrowth has also entered into an agreement to sell its non-operated Weyburn property for proceeds of $315 million (prior to closing adjustments) which is expected to close in early March 2013. We do not expect a material gain or loss on
this transaction. During the third quarter of 2012, Pengrowth acquired properties in the Lone Pine Creek area for $5.4 million and disposed of various
wells in the Cactus Lake, Plover, Twining and Swalwell areas for proceeds of $15 million, resulting in a gain on disposition of $8.1 million. In the
second quarter of 2012, Pengrowth completed the NAL Acquisition for $965.7 million and additional producing properties in the Sawn Lake area for $15.5 million. In the first quarter of 2012, Pengrowth exercised rights of first refusal in the Quirk Creek Field and the Weyburn Unit, increasing its working interest in each. The purchase prices were $13.5 million and $12.3
million net of adjustments, respectively. WORKING CAPITAL At December 31, 2012, Pengrowth had a working capital surplus as current assets exceeded current liabilities by $128.8 million. In contrast, on December 31, 2011, Pengrowth had a working capital
deficiency of $137.3 million. The change in the working capital was due to the inclusion of $317.3 million of Weyburn assets held for sale partly offset by the current liabilities associated with these assets and the inclusion of the current portion
of long term debt, U.S. $50 million, maturing in April of 2013.

The ratio in the table only includes seven months of Adjusted EBITDA from the NAL acquisition. Including the prior five months of NAL Adjusted EBITDA would
result in a debt to Adjusted EBITDA ratio of approximately 2.2x. At December 31, 2012, total debt increased $444.2 million from
December 31, 2011. In October 2012, Pengrowth issued U.S. $385 million equivalent in long term notes where the proceeds were used to pay down indebtedness under Pengrowths current credit facilities. The expansion of total debt year over
year also included convertible debentures assumed with the NAL Acquisition and increased borrowing in the term credit facility due to net acquisitions in 2012. The increase in total debt was partly mitigated by the strengthening Canadian dollar which drove down the Canadian equivalent of the U.S. denominated senior unsecured notes by $16.6 million from December 31,
2011. In contrast, the U.K. pound sterling denominated debt increased by $2.4 million due to a weaker Canadian dollar relative to the U.K. pound sterling year over year. The increase in total debt resulted in a trailing twelve months total debt to
Adjusted EBITDA ratio at December 31, 2012 of 2.5x (including seven months of NAL Adjusted EBITDA). Including the prior five months of NAL Adjusted EBITDA would result in a debt to Adjusted EBITDA ratio of approximately 2.2x. Term Credit Facilities Pengrowth maintains a $1 billion
revolving credit facility which was drawn by $160 million in borrowings and approximately $27.5 million in outstanding letters of credit at December 31, 2012. The credit facility includes an expansion feature of $250 million providing Pengrowth
with up to $1.25 billion of credit capacity from a syndicate of seven Canadian and three foreign banks. The revolving credit facility matures on November 29, 2015 and can be extended at Pengrowths discretion any time prior to maturity,
subject to syndicate approval.

##### Table of Contents

Pengrowth also maintains a $50 million demand operating facility with one Canadian bank. At December 31,
2012, this facility was undrawn and had approximately $0.9 million of outstanding letters of credit. When utilized together with any overdraft amounts, this facility appears on the Consolidated Balance Sheets as a current liability in bank
indebtedness. Together, these two facilities and the cash balance provided Pengrowth with approximately $864.9 million of available credit capacity at
December 31, 2012, with the ability to expand the facilities by an additional $250 million. Financial Covenants Pengrowths senior unsecured notes and credit facilities are subject to a number of covenants, all of which were met at all times during the preceding twelve
months, and at December 31, 2012. There were no changes to Pengrowths covenants in the twelve months ended December 31, 2012. All loan agreements can be found on SEDAR (www.sedar.com) filed under Other or
Material Document. The calculation for each financial covenant is based on specific definitions, is not in accordance with IFRS, is similar
to Adjusted EBITDA, and cannot be readily replicated by referring to Pengrowths Consolidated Financial Statements. The financial covenants are substantially similar between the credit facilities and the senior unsecured notes. Key financial covenants are summarized below:  1.
Total senior debt before working capital must not exceed 3.0 times EBITDA for the last four fiscal quarters;  2.
Total debt before working capital must not exceed 3.5 times EBITDA for the last four fiscal quarters;  3.
Total senior debt before working capital must be less than 50 percent of total book capitalization; and  4.
EBITDA must not be less than four times interest expense for the last four fiscal quarters. There may be instances, such as financing an acquisition, where it would be acceptable for total debt to trailing EBITDA to be temporarily offside. In the event of a significant acquisition, certain credit facility
financial covenants are relaxed for two fiscal quarters after the close of the acquisition. Pengrowth may prepare pro forma financial statements for debt covenant purposes and has additional flexibility under its debt covenants for a set period of
time. This would be a strategic decision recommended by management and approved by the Board of Directors with steps taken in the subsequent period to restore Pengrowths capital structure based on its capital management objectives. Failing a financial covenant may result in one or more of Pengrowths loans being in default. In certain circumstances, being in default of one loan will,
absent a cure, result in other loans also being in default. In the event that non-compliance continued, Pengrowth would have to repay, refinance or re-negotiate the terms and conditions of the debt and may have to suspend dividends to shareholders. If certain financial ratios reach or exceed certain levels, management may consider steps to improve these ratios. These steps may include, but are not
limited to property dispositions, reducing capital expenditures or dividends as well as raising equity. Details of these measures are included in Note 17 to the audited Consolidated Financial Statements. Convertible Debentures As a result of the NAL Acquisition,
Pengrowth assumed $349.0 million of subordinated convertible debentures at June 1, 2012. On June 22, 2012, approximately $50.5 million of the debentures were redeemed as a result of the change in control pursuant to the debenture
indentures. On August 31, 2012, $59.5 million of principal, on one series of the convertible debentures, matured and was repaid in cash.
Convertible debentures with an aggregate amount of $237.1 million were outstanding at December 31, 2012. See Note 9 to the audited Consolidated Financial Statements. Dividend Reinvestment Plan Pengrowths Dividend Reinvestment Plan (DRIP) allows shareholders to reinvest cash dividends in additional shares of the Corporation. Under the DRIP, the shares are issued from treasury at a 5 percent
discount to the weighted average closing price of Pengrowths common shares as determined by the plan. On January 3, 2012, Pengrowth
announced that it had introduced a Premium Dividend program. This program was suspended effective December 17, 2012.

##### Table of Contents

During the year ended December 31, 2012, 19.3 million shares were issued for cash proceeds of $135.9
million under the DRIP (including the Premium Dividend) program, compared to 5.0 million shares issued for cash proceeds of $54.7 million in 2011. Property Divestments In addition to the $315 million Weyburn disposition which is expected to close in early
March 2013, Pengrowth has also announced its intention to raise up to $700 million from additional property divestments in 2013. These proceeds will be used for debt repayment and capital expenditures, including Lindbergh. Pengrowth does not have any off balance sheet financing arrangements. FINANCIAL INSTRUMENTS Pengrowth uses financial instruments to manage its exposure to commodity price
fluctuations, foreign currency and interest rate exposures. Pengrowths policy is not to utilize financial instruments for trading or speculative purposes. See Note 2 to the audited Consolidated Financial Statements, for a description of the
accounting policies for financial instruments and Note 18 to the audited Consolidated Financial Statements for additional information regarding market risk, credit risk, liquidity risk and the fair value of Pengrowths financial instruments.

Payout Ratio is calculated as dividends declared divided by Funds Flow from Operations. As a result of the depleting nature of Pengrowths oil and gas assets, capital expenditures are required to offset production declines while other capital is
required to maintain facilities, acquire prospective lands and prepare future projects. Capital spending and acquisitions may be funded by the excess of Funds Flow from Operations less dividends declared, through the sale of existing properties,
additional debt or the issuance of equity. Pengrowth does not deduct capital expenditures when calculating Funds Flow from Operations. Funds Flow from
Operations is derived from producing and selling oil, natural gas and related products and is therefore highly dependent on commodity prices. Pengrowth enters into forward commodity risk management contracts to mitigate price volatility and to
provide a measure of stability to monthly cash flow. Details of commodity risk management contracts are contained in Note 18 to the audited Consolidated Financial Statements. The following table provides the Net Payout Ratio when the proceeds of the Dividend Reinvestment and Premium DividendTMplans are accounted for to reflect Pengrowths net cash outlay:  Three months ended

##### Table of Contents

DIVIDENDS Pengrowth recognizes the importance of its dividend to shareholders. The Board of Directors and management regularly review the level of dividends. The board considers a number of factors, including expectations of
future commodity prices, capital expenditure requirements, and the availability of debt and equity capital. As a result of the volatility in commodity prices, changes in production levels and capital expenditure requirements, there can be no
certainty that Pengrowth will be able to maintain current levels of dividends and dividends can and may fluctuate in the future. Pengrowth has no restrictions on the payment of its dividends other than maintaining its financial covenants in its
borrowings and restrictions in the Alberta Business Corporations Act. Dividends are generally paid to shareholders on or about the fifteenth day of the
month. Pengrowth paid $0.07 per share in each of the months January through July 2012 and $0.04 per share in each of the months August through December 2012, for an aggregate annual cash dividend of $0.69 per share for the full year 2012. In 2011,
Pengrowth paid a monthly dividend of $0.07 per share for an aggregate annual cash dividend of $0.84 per share. SUMMARY OF QUARTERLY

##### Table of Contents

Production increased in the second, third and fourth quarters of 2012, primarily as a result of the NAL
Acquisition on May 31, 2012. In addition to natural declines, production changes over these quarters were a result of production limitations due to a SOEP Venture platform outage in the third and fourth quarters of 2012, first quarter of 2011
unscheduled pipeline outage, second quarter 2011 scheduled maintenance shutdowns and restrictions due to flooding and forest fires. Quarterly net
income (loss) has also been affected by non-cash charges, in particular depletion, depreciation and amortization, impairment charges, gain on acquisition, unrealized gain (loss) on investments, accretion of ARO, unrealized risk management gains
(losses), unrealized foreign exchange gains (losses), and deferred taxes. Funds Flow from Operations was also impacted by changes in royalty expense, operating and general and administrative costs. SELECTED ANNUAL INFORMATION The table below

Cdn BUSINESS RISKS The
following factors should not be considered exhaustive. Additional risks are outlined in the AIF of the Corporation which is available on SEDAR at www.sedar.com. The amount of dividends available to shareholders and the value of Pengrowth common shares are subject to numerous risk factors. Pengrowths principal source of net cash flow is from Pengrowths portfolio
of producing oil and natural gas properties, the principal risk factors that are associated with our business include, but are not limited to, the following: Risks associated with Commodity Prices 

The prices of Pengrowths products (crude oil, natural gas, and NGLs) fluctuate due to many factors including local and global market supply and demand,
weather patterns, availability of pipeline and rail transportation capacity, availability of refining capacity, discount for Western Canadian light and heavy oil and natural gas, and political and economic stability.  

Production could be shut-in at specific wells or fields in light of low commodity prices.  

Substantial and sustained reductions in commodity prices or equity markets, including Pengrowths share price, in some circumstances could result in
Pengrowth recording an impairment loss as well as affecting the ability to maintain the current dividends, spend capital and meet obligations. The impairment test is sensitive to lower commodity prices, which have been under significant downward
pressure in recent periods, particularly natural gas prices. Further declines in commodity prices in 2013 could result in additional impairment charges as the cushions in the CGU impairment tests have been eroded by price decreases. Risks associated with Liquidity 

Capital markets may restrict Pengrowths access to capital and raise its borrowing costs. To the extent that external sources of capital become limited or
cost prohibitive, Pengrowths ability to fund future development and acquisition opportunities may be impaired.  

Pengrowth is exposed to third party credit risk through its oil and gas sales, financial hedging transactions and joint venture activities. The failure of any of
these counterparties to meet their contractual obligations could adversely impact Pengrowth.  

Changing interest rates influence borrowing costs and the availability of capital.  

Failing a financial covenant may result in one or more of Pengrowths loans being in default. In certain circumstances, being in default of one loan will
result in other loans also being in default. In the event that non-compliance continued, Pengrowth would have to repay the debt, refinance the debt or negotiate new terms with the debt holders and may have to suspend dividends to shareholders.  

Pengrowths indebtedness may limit the amount of dividends that we are able to pay our shareholders, and if we default on our debts, the net proceeds of any
foreclosure sale would be allocated to the repayment of our lenders, note holders and other creditors and only the remainder, if any, would be available for distribution to our shareholders.  

Uncertainty in international financial markets could lead to constrained capital markets, increased cost of capital and negative impact on economic activity and
commodity prices.

##### Table of Contents

Risks associated with Legislation and Regulatory Changes 

Government royalties, income taxes, commodity taxes and other taxes, levies and fees have a significant economic impact on Pengrowths financial results.
Changes to federal and provincial legislation governing such royalties, taxes and fees could have a material impact on Pengrowths financial results and the value of Pengrowths common shares.  

Environmental laws and regulatory initiatives impact Pengrowth financially and operationally. We may incur substantial capital and operating expenses to comply
with increasingly complex laws and regulations covering the protection of the environment and human health and safety. In particular, we may be required to incur significant costs to comply with future regulations to reduce greenhouse gas and other
emissions.  

Regulations surrounding the fracture stimulation of wells, including increasing disclosure and restrictions, differ and depend on the area of operation.
Pengrowth may have to adjust its operational practices, increase compliance and incur additional costs as a result.  

Changes to accounting policies may result in significant adjustments to our financial results, which could negatively impact our business, including increasing
the risk of failing a financial covenant contained within our credit facility. Risks associated with Operations 

The marketability of our production depends in part upon the availability, proximity and capacity of gathering systems, pipelines, rail lines and processing
facilities. Operational or economic factors may result in the inability to deliver our products to market.  

Increased competition for properties could drive the cost of acquisitions up and expected returns from the properties down.  

Timing of oil and gas operations is dependent on gaining timely access to lands. Consultations, that are mandated by governing authorities, with all stakeholders
(including surface owners, First Nations and all interested parties) are becoming increasingly time consuming and complex, and have a direct impact on cycle times.  

Availability of specialized equipment, goods and services, during periods of increased activity within the oil and gas sector, may adversely impact timing of
operations.  

Oil and gas operations can be negatively impacted by certain weather conditions, including floods, forest fires and other natural events, which
may restrict production and/or delay drilling activities.  

A significant portion of Pengrowths properties are operated by third parties whereby Pengrowth has less control over the pace of capital and operating
expenditures. If these operators fail to perform their duties properly, or become insolvent, we may experience interruptions in production and revenues from these properties or incur additional liabilities and expenses as a result of the default of
these third party operators.  

Geological and operational risks affect the quantity and quality of reserves and the costs of recovering those reserves. Our actual results will vary from our
reserve estimates and those variations could be material.  

Oil and gas operations carry the risk of damaging the local environment in the event of equipment or operational failure. The cost to remediate any environmental
damage could be significant.  

Delays in business operations could adversely affect Pengrowths dividends to shareholders and the market price of the common shares.  

During periods of increased activity within the oil and gas sector, the cost of goods and services may increase substantially.  

During times of increased activity it may be more difficult to hire and retain staff and the cost for skilled labour may increase substantially.  

Attacks by individuals against facilities and any such attacks, or the threat thereof, may have an adverse impact on Pengrowth and the implementation of security
measures as a precaution against possible attacks would result in increased cost to Pengrowths business.  

Actual production and reserves will vary from estimates, and those variations could be material and may negatively affect the market price of the common shares
and dividends to our shareholders.  

Delays or failure to secure regulatory approvals for thermal projects may result in capital being spent with reduced economics, reduced or no further reserves
being booked, and reduced or no associated future production and cash flow.

##### Table of Contents



The performance and results of a thermal project such as Lindbergh is dependent on the ability of the steam to access the reservoir and efficiently move
additional heavy oil that would otherwise remain trapped within the reservoir rock. The amount and cost of steam required, the additional oil recovered, the quality of the oil produced, the ability to recycle produced water into steam and the
ability to manage costs will determine the economic viability for a thermal project.  

The success of a thermal project such as Lindbergh will depend, in part, on our ability to sell our production at a desirable price. Current transportation and
refining constraints have resulted in a volatile price environment with a substantial discount (differential) being paid for heavy oil and bitumen. Risks associated with Strategy 

Capital re-investment on our existing assets may not yield the expected benefits and related value creation. Drilling opportunities may prove to be more costly
or less productive than anticipated. In addition, the dedication of a larger percentage of our cash flow to such opportunities may reduce the funds available for dividend payment to shareholders. In such an event, the market value of the common
shares may be adversely affected.  

Pengrowths oil and gas reserves will be depleted over time and our level of cash flow from operations and the value of our common shares could be reduced
if reserves and production are not replaced. The ability to replace production depends on the amount of capital invested and success in developing existing reserves, acquiring new reserves and financing this development and acquisition activity
within the context of the capital markets.  

Incorrect assessments of value at the time of acquisitions could adversely affect the value of our common shares and dividends to our shareholders.  

Our dividends and the market price of the common shares could be adversely affected by unforeseen title defects, which could reduce dividends to our
shareholders. General Business Risks 

Investors interest in the oil and gas sector may change over time which would affect the availability of capital and the value of Pengrowth common shares.  

Inflation may result in escalating costs, which could impact dividends and the value of Pengrowth common shares.  

Canadian / U.S. exchange rates influence revenues and, to a lesser extent, operating and capital costs. Pengrowth is also exposed to foreign currency
fluctuations on the U.S. dollar denominated notes for both interest and principal payments.  

Failure to receive regulatory approval or the expiry of the rights to explore for E&E assets could lead to the impairment of E&E assets. These factors should not be considered exhaustive. Additional risks are outlined in the AIF of the Corporation which is available on
SEDAR at www.sedar.com. FUTURE CHANGES IN ACCOUNTING POLICIES Accounting Policies adopted January 1, 2013 Pengrowth adopted IFRS 10 Consolidated Financial
Statements, IFRS 11 Joint Arrangements, IFRS 12 Disclosures of Interests in Other Entities, as well as the consequential amendments to IAS 28 Investments in Associates and Joint Ventures (2011) and IFRS 13 Fair Value Measurement, with a date of
initial application of January 1, 2013. The adoption of these standards on January 1, 2013 will have no impact on the amounts recorded in the
Corporations Consolidated Financial Statements. IFRS 10: Consolidated Financial Statements (IFRS 10) IFRS 10 introduces a new control model that is applicable to all investees; among other things, it requires the consolidation of an investee if the Corporation
controls the investee on the basis of de facto circumstances. Subsidiaries are entities controlled by the Corporation. The Corporation controls an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity
and has the ability to affect those returns through its power over the entity. The financial statements of subsidiaries are included in the Consolidated Financial Statements from the date that control commences until the date that control ceases. On January 1, 2013, the Corporation had wholly owned subsidiaries, none of which hold any significant assets (holding companies). The
determination of whether to consolidate these entities does not involve any significant judgments or assumptions. There are no

significant restrictions on the ability of the Corporation to access or use the assets, and settle the liabilities of the Corporation and its subsidiaries except for customary limitations in the
Corporations credit facility (i.e. notification of significant dispositions). IFRS 11: Joint Arrangements (IFRS 11) Joint arrangements are arrangements of which the Corporation has joint control, established by contracts requiring unanimous consent for decisions
about the activities that significantly affect the arrangements returns. Under IFRS 11, joint arrangements are classified as either joint operations or joint ventures depending on the Corporations rights to the assets and obligations for
the liabilities of the arrangements. When making this assessment, the Corporation considers the structure of the arrangements, the legal form of any separate vehicles, the contractual terms of the arrangement and other facts and circumstances.
Previously, the structure of the arrangement was the sole focus of classification. The Corporation has no joint arrangements under IFRS 11. A
significant portion of the Corporations oil and gas activities are conducted with others, however, these are considered jointly controlled assets and are outside the scope of IFRS 11. These Consolidated Financial Statements reflect only the
Corporations proportionate share of the related assets, obligations, revenue and expenses of jointly controlled assets. IFRS 12: Disclosures
of Interests in Other Entities (IFRS 12) IFRS 12 sets out certain disclosures that are required relating to interests in subsidiaries,
associates, joint arrangements and unconsolidated structured entities. The Corporation does not have any investments that are not consolidated nor has it entered into any joint arrangements or structured entities. IFRS 13: Fair Value Measurement (IFRS 13) IFRS
13 defines fair value, sets out a single standard framework for measuring fair value and the required disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a
liability in an orderly transaction between market participants at the measurement date. IFRS 13 is applied prospectively to fair value measurements
occurring on or after January 1, 2013. The additional disclosure requirements of IFRS 13 are also applied prospectively and will be presented, as relevant, in the 2013 interim and annual financial statements. Accounting policies not yet adopted IFRS 9:
Financial Instruments (IFRS 9) IFRS 9 is expected to be published in three parts. The first part, Phase 1classification and
measurement of financial instruments (IFRS 9, Phase 1), was published in October 2010. IFRS 9, Phase 1, sets out the requirements for recognizing and measuring financial assets, financial liabilities and some contracts to buy or sell non-financial
items. IFRS 9, Phase 1 simplifies measurement of financial assets by classifying all financial assets as those being recorded at amortized cost or being recorded at fair value. For financial assets recorded at fair value, any change in the fair
value would be recognized in net income. IFRS 9, Phase 1, is required to be adopted for years beginning on or after January 1, 2015 although earlier adoption is allowed. Pengrowth has not made any decision as to early adoption and based on a
preliminary assessment this standard should not have a material impact on Pengrowth. Amendments to IAS 32 Financial Instruments: Presentation
(IAS 32) and IFRS 7: Financial Instruments: Disclosures (IFRS 7) Offsetting Financial Assets and Financial Liabilities: Amendments to IAS 32 and IFRS 7, was published
in December 2011. The amendments to IAS 32 clarify the requirements for offsetting financial instruments. The amendments to IFRS 7 introduce new disclosure requirements for financial assets and financial liabilities that are offset in the
Consolidated Balance Sheets, or are subject to enforceable master netting arrangements or similar agreements. The amendment to IFRS 7 is applied
retrospectively for annual periods beginning on or after January 1, 2013, while amendments to IAS 32 is applied retrospectively for annual periods beginning on or after January 1, 2014. Pengrowth has not made any decision as to early
adoption of IAS 32 and it is expected that these standards will not have a material impact on Pengrowth. DISCLOSURE AND INTERNAL
CONTROLS As a Canadian reporting issuer with securities listed on both the TSX and the NYSE, Pengrowth is required to comply with Multilateral
Instrument 52-109Certification of Disclosure in Issuers Annual and Interim Filings, as well as the Sarbanes Oxley

Act (SOX) enacted in the United States. Both the Canadian and U.S. certification
rules include similar requirements where both the Chief Executive Officer (CEO) and the Chief Financial Officer (CFO) must assess and certify as to the effectiveness of the disclosure controls and procedures as defined in Canada by Multilateral Instrument
52-109Certification of Disclosure in Issuers Annual and Interim Filings and in the United States by Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended. The CEO, Derek Evans, and the CFO, Christopher Webster, evaluated the effectiveness of Pengrowths disclosure controls and procedures for the year ending
December 31, 2012. This evaluation considered the functions performed by its Disclosure Committee, the review and oversight of all executive officers and the board, as well as the process and systems in place for filing regulatory and public
information. Pengrowths established review process and disclosure controls are designed to provide reasonable assurance that all required information, reports and filings required under Canadian securities legislation and United States
securities laws are properly submitted and recorded in accordance with those requirements. Based on that evaluation, the CEO and CFO concluded that the
design and operation of our disclosure controls and procedures were effective at the reasonable assurance level as at December 31, 2012, to ensure that information required to be disclosed by us in reports that we file under Canadian and U.S.
securities laws is gathered, recorded, processed, summarized and reported within the time periods specified under Canadian and U.S. securities laws and is accumulated and communicated to the management of Pengrowth Energy Corporation, including the
CEO and CFO, to allow timely decisions regarding required disclosure as required under Canadian and U.S. securities laws. It should be noted that while
Pengrowths CEO and CFO believe that Pengrowths disclosure controls and procedures provide a reasonable level of assurance that they are effective, they do not expect that Pengrowths disclosure controls and procedures or internal
control over financial reporting will prevent all errors and fraud. A control system, no matter how well conceived or operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. INTERNAL CONTROL OVER FINANCIAL REPORTING Our
management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended and in Canada as defined in Multilateral
Instrument 52-109Certification of Disclosure in Issuers Annual and Interim Filings. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of our financial reporting and the
preparation of our Consolidated Financial Statements for external purposes in accordance with IFRS for note disclosure purposes. Our internal control over financial reporting includes those policies and procedures that: pertain to the maintenance of
records that in reasonable detail accurately and fairly reflect our transactions and disposition of the assets; provide reasonable assurance that transactions are recorded as necessary to permit preparation of our Consolidated Financial Statements
in accordance with IFRS and that receipts and expenditures of our assets are being made only in accordance with authorizations of our management and directors; and provide reasonable assurance regarding prevention or timely detection of unauthorized
acquisition, use or disposition of our assets that could have a material effect on our Consolidated Financial Statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our internal
control over financial reporting as of December 31, 2012. In making this evaluation, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework. Based on our
evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2012. The effectiveness
of internal control over financial reporting as of December 31, 2012 was audited by KPMG LLP, an independent registered public accounting firm, as stated in their report, which is included with our audited Consolidated Financial Statements for
the year ended December 31, 2012. No changes were made to our internal control over financial reporting during the year ending December 31, 2012 that have materially affected, or are reasonably likely to materially affect, the internal
controls over financial reporting. Pengrowths audited Consolidated Financial Statements contain financial information from the acquisition date
of NAL to August 31, 2012 that was generated using a third party managers internal controls over financial reporting. The net revenue generated during this period was $86 million.

FINANCIAL STATEMENTS OF PENGROWTH ENERGY CORPORATION, INCLUDING MANAGEMENTS REPORT TO SHAREHOLDERS AND THE AUDITORS REPORTS



---

##### Table of Contents

MANAGEMENTS REPORT TO SHAREHOLDERS Managements Responsibility to Shareholders The
Consolidated Financial Statements and the notes to the Consolidated Financial Statements are the responsibility of the management of Pengrowth Energy Corporation. They have been prepared in accordance with International Financial Reporting Standards
(IFRS) as issued by the International Accounting Standards Board which have been adopted in Canada. Financial information that is presented
in the Management Discussion and Analysis is consistent with the Consolidated Financial Statements. In preparation of these statements, estimates are
sometimes necessary because a precise determination of certain assets and liabilities is dependant on future events. Management believes such estimates have been based on careful judgments and have been properly reflected in the accompanying
Consolidated Financial Statements. Management is responsible for the reliability and integrity of the Consolidated Financial Statements, the notes to
the Consolidated Financial Statements, and other financial information contained in this report. In order to ensure that management fulfills its responsibilities for financial reporting we have established an organizational structure that provides
appropriate delegation of authority, division of responsibilities, and selection and training of properly qualified personnel. Management is also responsible for the development of internal controls over the financial reporting process. The Board of Directors (the Board) is assisted in
exercising its responsibilities through the Audit and Risk Committee (the Committee) of the Board, which is composed of four independent
directors. The Committee meets regularly with management and the independent auditors to satisfy itself that managements responsibilities are properly discharged, to review the Consolidated Financial Statements and to recommend approval of the
Consolidated Financial Statements to the Board. KPMG LLP, the independent auditors appointed by the shareholders, have audited Pengrowth Energy
Corporations Consolidated Financial Statements in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States) and provided an independent professional
opinion. The auditors have full and unrestricted access to the Committee to discuss the audit and their related findings as to the integrity of the financial reporting process.  LOGO

INDEPENDENT AUDITORS REPORT OF REGISTERED PUBLIC ACCOUNTING FIRM TO THE
SHAREHOLDERS AND BOARD OF DIRECTORS OF PENGROWTH ENERGY CORPORATION We have audited the accompanying consolidated financial statements of Pengrowth
Energy Corporation (the Corporation), which comprise the consolidated balance sheets as at December 31, 2012 and December 31, 2011, the consolidated statements of income, shareholders equity and cash flow for the years then
ended, and notes, comprising a summary of significant accounting policies and other explanatory information. MANAGEMENTS
RESPONSIBILITY FOR THE CONSOLIDATED FINANCIAL STATEMENTS Management is responsible for the preparation and fair presentation of these consolidated
financial statements in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board, and for such internal control as management determines is necessary to enable the preparation of
consolidated financial statements that are free from material misstatement, whether due to fraud or error. AUDITORS
RESPONSIBILITY Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in
accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we comply with ethical requirements and plan and perform the audit to
obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement. An audit involves performing
procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on our judgment, including the assessment of the risks of material misstatement of the consolidatedfinancial statements, whether due to fraud or error. In making those risk assessments, we consider internal control relevant to the entitys preparation and
fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of
accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that the
audit evidence we have obtained in our audits is sufficient and appropriate to provide a basis for our audit opinion. OPINION In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Corporation
as at December 31, 2012 and December 31, 2011, and its consolidated financial performance and its consolidated cash flows for the years then ended in accordance with International Financial Reporting Standards as issued by the International
Accounting Standards Board. OTHER MATTER We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Corporations internal control
over financial reporting as of December 31, 2012, based on the criteria established in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated
February 28, 2013 expressed an unqualified opinion on the effectiveness of the Corporations internal control over financial reporting.  LOGOChartered AccountantsCalgary, CanadaFebruary 28, 2013

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM TO THE SHAREHOLDERS AND BOARD OF DIRECTORS OF PENGROWTH ENERGY
CORPORATION We have audited Pengrowth Energy Corporations (the Corporation) internal control over financial reporting as of
December 31, 2012, based on the criteria established in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Corporations management is responsible for
maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Managements Report to the Shareholders. Our responsibility
is to express an opinion on the Corporations internal control over financial reporting based on our audit. We conducted our audit in accordance
with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was
maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of
internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. An entitys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. An entitys internal control over financial reporting includes those policies and procedures that (1) pertain to
the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the entity; (2) provide reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the entity are being made only in accordance with authorizations of management and directors of the entity; and
(3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the entitys assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. In our opinion, the Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on
the criteria established in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). We also have audited, in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of the
Corporation as of December 31, 2012 and December 31, 2011, and the related consolidated statements of income, shareholders equity and cash flow for the years then ended, and our report dated February 28, 2013 expressed an unqualified
opinion on those consolidated financial statements.  LOGOChartered AccountantsCalgary, CanadaFebruary 28, 2013

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS AS AT AND FOR THE YEARS ENDED DECEMBER 31, 2012 and 2011 (Tabular
amounts are stated in thousands of dollars except per share amounts and as otherwise stated)  1.
BUSINESS OF THE CORPORATION Pengrowth Energy Corporation
(Pengrowth or the Corporation) is
a Canadian resource company that is engaged in the production, development, exploration and acquisition of oil and natural gas assets. The Consolidated Financial Statements include the accounts of the Corporation, and all of its subsidiaries,
collectively referred to as Pengrowth. All inter-entity transactions have been eliminated.  2.
SIGNIFICANT ACCOUNTING POLICIES BASIS OF
PRESENTATION These Consolidated Financial Statements have been prepared in accordance with the International Financial Reporting Standards
(IFRS) issued by the International Accounting Standards Board (IASB) and International Financial Reporting Interpretations Committee (IFRIC). The Consolidated Financial Statements were authorized for release by the Board of Directors on February 28, 2013. PROPERTY, PLANT AND EQUIPMENT (PP&E) AND EXPLORATION AND EVALUATION (E&E) ASSETS Pengrowth capitalizes all costs of developing and acquiring oil and gas properties. These costs include lease acquisition costs, geological and geophysical
expenditures, costs of drilling and completion of wells, plant and production equipment costs and related overhead charges. Pengrowth capitalizes a portion of general and administrative costs and share based compensation expense associated with
exploration and development activities. Repairs and maintenance costs are expensed as incurred. Exploration and Evaluation Assets Costs of exploring for and evaluating oil and natural gas properties are capitalized within E&E assets. These E&E assets include lease acquisition costs,
geological and geophysical expenditures, costs of drilling and completion of wells, plant and production equipment costs and related overhead charges. E&E assets do not include costs of general prospecting, or evaluation costs incurred prior to
having obtained the legal rights to explore an area, which are expensed as incurred. Interest is not capitalized on E&E assets. E&E assets are
not depleted or depreciated and are carried forward until technical feasibility and commercial viability is considered to be determined. The technical feasibility and commercial viability is generally considered to be determined when proved plus
probable reserves are determined to exist and the commercial production of oil and gas has commenced. A review of each exploration license or field is carried out, at least annually, to ascertain whether the project is technically feasible and
commercially viable. Upon determination of technical feasibility and commercial viability, E&E assets attributable to those reserves are first tested for impairment and then reclassified from E&E assets to PP&E. Property, Plant and Equipment PP&E is stated at cost;
less accumulated depletion, depreciation and amortization, and accumulated impairment losses. The initial cost of an asset comprises its purchase price or construction cost, costs attributable to bringing the asset into operation, the initial
estimate of asset retirement obligation and, for qualifying assets, borrowing costs. When significant parts of an item of PP&E, including oil and natural gas interests, have different useful lives, they are accounted for as separate items. Subsequent Costs Costs incurred subsequent to
the determination of technical feasibility and commercial viability and the costs of replacing parts of PP&E are recognized as oil and natural gas interests only when they increase the future economic benefits embodied in the specific asset to
which they relate. Such capitalized oil and natural gas interests generally represent costs incurred in developing proved and/or probable reserves and bringing in or enhancing production from such reserves, and are accumulated on a field or
geotechnical area basis. The carrying amount of any replaced or sold component is derecognized. The costs of the day-to-day servicing of PP&E are
expensed as incurred.

Pengrowth capitalizes a portion of general and administrative costs directly associated with exploration and
development activities. Pengrowth capitalizes interest incurred in construction of qualifying assets, if applicable. Qualifying assets are defined by Pengrowth as capital projects that require capital expenditures over a period greater than one
year, in order to produce oil or gas from a specific property. Dispositions Gains or losses are recognized in the Consolidated Statements of Income on dispositions of PP&E and certain E&E assets, including asset swaps, farm-out transactions and property dispositions. The gain or
loss is measured as the difference between the fair value of the proceeds received and the carrying value of the assets disposed, including capitalized future asset retirement obligations. Depletion and Depreciation The net carrying value of developed or producing fields or groups of fields is
depleted using the unit of production method by reference to the ratio of production in the period to the related proved plus probable reserves, taking into account estimated future development capital necessary to bring those reserves into
production. Future development capital is estimated taking into account the level of development required to produce the reserves. These estimates are reviewed by independent reserve engineers at least annually. Pengrowths total proved plus
probable reserves are estimated by an independent reserve evaluator and represent the best estimate of quantities of oil, natural gas and related substances to be commercially recoverable from known accumulations, from a given date
forward, based on geological and engineering data. It is equally likely that the actual remaining quantities recovered will be greater than or less than the sum of the estimated proved plus probable reserves. Properties with no remaining production
and reserves are fully depleted in the year that production ceases. For other assets, depreciation is recognized in the Consolidated Statements of
Income using either a straight line or declining balance basis over the estimated useful lives of each part of an item of PP&E. The estimated useful lives for other assets for the current and comparative periods are as follows:   Office equipment

60 months Leasehold improvements and finance leases

Lease term/Useful life Computers

36 months Deferred hydrocarbon injectants

24 months Depreciation methods, useful lives and residual values are reviewed annually. Farmouts Under IFRS, farmouts are considered a disposition
of a partial interest in a property. The proceeds on the disposition is the capital spent, or estimated to be spent, by the farmee in order to earn the interest. The difference between the estimated capital and the carrying value of the disposed
interest would be recorded as a gain or loss on disposition on the Consolidated Statements of Income. When the agreed upon work commitment has been completed, the farmee has earned their interest. It is at this stage that Pengrowth would record a
gain or loss on disposition. If the farm-out results in a Gross Overriding Royalty (GOR) being retained by Pengrowth, rather than a working interest, a value is assigned to the GOR which then represents the deemed proceeds. LEASED ASSETS Assets held by Pengrowth under leases which transfer to the Corporation substantially
all of the risks and rewards of ownership are classified as finance leases. On initial recognition, the leased asset is measured at an amount equal to the lower of its fair value and the present value of the minimum lease payments. Subsequent to
initial recognition, the asset is accounted for in accordance with the accounting policy applicable to that asset. Minimum lease payments made under finance leases are apportioned between the finance expense and the reduction of the outstanding
liability. The finance expense is allocated to each period during the lease term so as to produce a constant periodic rate of interest on the remaining balance of the liability. Assets held under other leases are classified as operating leases and are not recognized in the Consolidated Balance Sheets. Payments made under operating leases are recognized in the Consolidated Statements of
Income on a straight-line basis over the term of the lease. Lease incentives received are recognized as an integral part of the total lease expense, over the term of the lease.

##### Table of Contents

At inception of certain arrangements, the Corporation determines whether such arrangement is or contains a lease.
This will be the case if the following two criteria are met:  

The fulfillment of the arrangement is dependent on the use of a specific asset or assets; and  

The arrangement contains the right to use the asset(s). GOODWILL AND BUSINESS COMBINATIONS Goodwill Goodwill may arise on business combinations. Goodwill is stated at cost less accumulated impairment. Goodwill represents the excess of the cost of the acquisition over the net fair value of the identifiable assets, liabilities and contingent liabilities of the acquired assets or company. When the excess is
negative, it is recognized immediately in the Consolidated Statements of Income. IMPAIRMENT Non-Financial Assets Property, Plant and Equipment For the purpose of impairment testing, PP&E is grouped together into the smallest group of assets that generate cash inflows from continuing use
that are largely independent of the cash inflows of other assets or groups of assets  cash generating unit (the CGU). CGUs are tested for impairment at least annually or when there is an indication of impairment, such as decreased commodity prices or downward revisions in reserves
volumes. An impairment loss is recognized to the extent the carrying value of the CGU exceeds its recoverable amount. Impairment losses are recognized in the Consolidated Statements of Income. The recoverable amount of a CGU is the higher of its value in use and the fair value less costs to sell. However, for properties such as Pengrowths, these
amounts are generally the same. In determining the recoverable amount, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the cost of capital, which take
into account the time value of money and the risks specific to the asset. The recoverable amount is generally computed by reference to the present value of the future cash flows expected to be derived from production of proved and probable reserves.
Undeveloped land and contingent resources are also considered in the recoverable amount. Impairment losses recognized in respect of CGUs are allocated
first to reduce the carrying amount of any goodwill allocated to the units and then to reduce the carrying amounts of the other assets in the unit on a pro rata basis. Impairment losses in respect of PP&E recognized in prior periods are assessed at each reporting date for any indications that the loss has decreased or no longer exists. In such circumstances, the recoverable
amount is determined and to the extent the loss is reduced, it is reversed. An impairment loss is reversed only to the lesser of the revised recoverable amount or the carrying amount that would have been determined, net of depletion and depreciation
or amortization, if no impairment loss had been recognized. Exploration and Evaluation Assets E&E assets are tested for impairment where there is an indication that a particular E&E project may be impaired. Examples of indicators of impairment
include the decision to no longer pursue the E&E project, an expiry of the rights to explore in an area, or failure to receive regulatory approval. In addition, E&E assets are assessed for impairment upon their reclassification to producing
assets (oil and natural gas interests in PP&E). In assessing the impairment of E&E assets, the carrying value of the E&E assets would be compared to their estimated recoverable amount and, in certain circumstances, could include any
surplus from PP&E impairment testing of related CGUs. The impairment of E&E assets and any eventual impairment thereof would be recognized in the Consolidated Statements of Income. Goodwill For goodwill and other intangible assets that have indefinite lives or that are not yet available for
use, an impairment test is completed each year at December 31. In assessing the impairment of goodwill, the carrying value of goodwill is compared to the excess of the recoverable amount over the carrying amount of the PP&E and E&E
assets, as applicable, within the CGU or groups of CGUs where the acquired properties are grouped. An impairment loss is recognized if the carrying amount of the goodwill exceeds the excess of the recoverable amount above the carrying amount of the
CGU or CGUs. An impairment loss in respect of goodwill cannot be reversed.

##### Table of Contents

Financial Assets A financial asset is assessed at each reporting date to determine whether there is any objective evidence that it is impaired. A financial asset is considered to be impaired if objective evidence, including failure
to pay on time, indicates that one or more events have had a negative effect on the estimated future cash flows of that asset. An impairment loss in
respect of a financial asset measured at amortized cost is calculated as the difference between its carrying amount and the present value of the estimated future cash flows discounted at the original effective interest rate. Significant financial
assets are tested for impairment on an individual basis. The remaining financial assets are assessed collectively in groups that share similar credit risk characteristics. All impairment losses are recognized in the Consolidated Statements of Income. An impairment loss is reversed if the reversal can be related objectively to an event occurring after the impairment loss was
recognized. For financial assets measured at amortized cost, the reversal is recognized in the Consolidated Statements of Income. PROVISIONS A provision is recognized if, as a
result of a past event, the Corporation has a present legal or constructive obligation that can be estimated reliably and it is probable that an outflow of economic benefits will be required to settle the obligation. Provisions are determined by
discounting the expected future cash flows at a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the liability. Provisions are not permitted for future operating losses. Asset Retirement Obligations (ARO) Pengrowth initially recognizes the net present value of an ARO in the period in which it is incurred when a reasonable estimate of the net present
value can be made. The net present value of the estimated ARO is recorded as a liability, with a corresponding increase in the carrying amount of the related asset. The capitalized asset is depleted on the unit of production method based on proved
plus probable reserves. The liability is increased each reporting period due to the passage of time and the amount of such accretion is expensed to income in the period. Actual costs incurred upon the settlement of the ARO are charged against the
ARO. Management reviews the ARO estimate and changes, if any, are applied prospectively. Revisions made to the ARO estimate are recorded as an increase or decrease to the ARO liability with a corresponding change made to the carrying amount of the
related asset. The carrying amount of both the liability and the capitalized asset, net of accumulated depreciation, are derecognized if the asset is subsequently disposed. Pengrowth has placed cash in segregated remediation trust fund accounts to fund certain ARO for the Judy Creek properties and the Sable Offshore Energy Project
(SOEP). These funds are reflected in Other Assets on the Consolidated Balance Sheets. Contract & Other Liabilities Provision Pengrowth
assumed firm pipeline commitments in conjunction with certain prior period acquisitions. The fair values of these contracts were estimated on the date of acquisition and the amount recorded is reduced as the contracts settle. Pengrowth also categorizes any finance lease transactions within this grouping. DEFERRED INCOME TAXES Income tax expense is comprised of current and deferred tax. Income tax expense
is recognized in the Consolidated Statements of Income except to the extent that it relates to items recognized directly in equity. Current tax is the
expected tax payable on the taxable income for the year, using tax rates enacted or substantively enacted at the reporting date, and any adjustment to tax payable in respect of previous years. Deferred tax is recognized using the asset and liability method of accounting for income taxes. Under this method, income tax liabilities and assets are recognized
for the estimated tax consequences attributable to differences between the amounts reported in the Consolidated Financial Statements and their respective tax bases, using substantively enacted income tax rates. The effect of a change in income tax
rates on deferred income tax liabilities and assets is recognized in income in the period the change occurs. Deferred tax assets and liabilities are offset if there is a legally enforceable right to offset current tax liabilities and assets, and
they relate to income taxes levied by the same tax authority on the same taxable entity. Pengrowths policy for income tax uncertainties is that
tax benefits will be recognized only when it is more likely than not the position will be sustained on examination.

SHARE BASED COMPENSATION PLANS Pengrowth has share based compensation plans, which are described in Note 14. Compensation expense is based on the estimated fair value of the share based compensation award at the date of grant. Compensation
expenses associated with the share based compensation plans are recognized in the Consolidated Statements of Income over the vesting period of the plan with a corresponding increase to contributed surplus. Pengrowth estimates the forfeiture rate for
each type of share based award at the date of grant. Any consideration received upon the exercise of the awards together with the amount of non-cash compensation expense recognized in contributed surplus is recorded as an increase in
shareholders capital at the time of exercise. Pengrowth does not have any outstanding share based compensation plans that call for settlement in
cash or other assets. Grants of such items, if any, will be recorded as liabilities, with changes in the liabilities charged to net income, based on the estimated fair value. FINANCIAL INSTRUMENTS Financial instruments are utilized by Pengrowth to manage its exposure to
commodity price fluctuations, foreign currency and interest rate exposures. Pengrowths policy is not to utilize financial instruments for trading or speculative purposes. Financial instruments are classified into one of five categories: (i) fair value through profit or loss, (ii) held to maturity investments, (iii) loans and receivables, (iv) available for sale
financial assets or (v) other liabilities. Accounts receivable are classified as loans and receivables which are measured at amortized cost. Investments held in the remediation trust funds and other investments have been designated as fair value through profit or loss and are measured at
fair value. Any change in the fair value is recognized in the Consolidated Statements of Income as other (income) expense. Bank indebtedness, accounts
payable, dividends payable, convertible debentures and long term debt have been classified as other liabilities which are measured at amortized cost using the effective interest rate method. All derivatives must be classified as held for trading and measured at fair value with changes in fair value over a reporting period recognized in net income. The receipts or payments arising from derivative commodity contracts are included in oil and gas sales, while unrealized gains and losses are presented as a
separate caption under revenues. The receipts or payments arising from derivative power and interest rate contracts are included in operating expenses
and interest expense. The unrealized gains and losses on derivative power and interest rate contracts are included in other (income) expense and interest expense. The receipts or payments arising from derivative foreign exchange contracts are presented as realized foreign exchange (gain) loss while the unrealized gains and losses are presented as unrealized foreign exchange
(gain) loss. Transaction costs incurred in connection with the issuance of term debt instruments with a maturity of greater than one year are deducted
against the carrying value of the debt and amortized to net income using the effective interest rate method over the expected life of the debt. Pengrowth capitalizes transaction costs incurred in connection with the renewal of the revolving credit facility with a maturity date greater than one year and
amortizes the cost to net income on a straight line basis over the term of the facility. FOREIGN CURRENCY The functional and reporting currency of the Corporation is Canadian dollars. Transactions in foreign currencies are translated to Canadian dollars at the exchange
rates on the date of the transactions. Monetary assets and liabilities denominated in foreign currencies are translated into Canadian dollars at the exchange rate in effect on the balance sheet date. Foreign exchange gains and losses are recognized
in net income. JOINTLY CONTROLLED OPERATIONS A significant proportion of Pengrowths petroleum and natural gas development and production activities are conducted through jointly controlled operations with others and accordingly, the accounts reflect
only Pengrowths interest in such activities.

RELATED PARTIES Related parties are persons or entities that have control or significant influence over Pengrowth, as well as key management personnel. Note 22 provides information on compensation expense related to key management
personnel. Pengrowth has no significant transactions with any other related parties. REVENUE RECOGNITION Revenue from the sale of oil and natural gas is recognized when the product is delivered and collection is reasonably assured. Revenue from processing and other
miscellaneous sources is recognized upon completion of the relevant service. EQUITY INVESTMENT Pengrowth utilizes the equity method of accounting for investments subject to significant influence, if applicable. Under this method, investments are initially
recorded at cost and adjusted thereafter to include Pengrowths pro rata share of post-acquisition earnings. Any dividends received or receivable from the investee would reduce the carrying value of the investment. ESTIMATES The preparation of financial statements
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingencies at the date of the financial statements and revenues and expenses during the reporting year. Actual
results could differ from those estimated. In particular, information about significant areas of estimation uncertainty and critical judgments in
applying accounting policies that have the most significant effect on the amounts recognized in the financial statements are described below: Estimating oil and gas reserves Pengrowth engages a
qualified, independent oil and gas reserves evaluator to perform an estimation of the Corporations oil and gas reserves at least annually. Reserves form the basis for the calculation of depletion charges and assessment of impairment of
goodwill and oil and gas assets. Reserves are estimated using the reserve definitions and guidelines prescribed by National Instrument 51-101 (NI 51-101) and the Canadian Oil and Gas Evaluation Handbook (COGEH). Proved plus probable reserves are defined as the best estimate of quantities of oil, natural gas and related substances estimated to be commercially
recoverable from known accumulations, from a given date forward, based on drilling, geological, geophysical and engineering data, the use of established technology and specified economic conditions. It is equally likely that the actual remaining
quantities recovered will be greater than or less than the sum of the estimated proved plus probable reserves. The estimates are made using all available geological and reservoir data as well as historical production data. Estimates are reviewed and
revised as appropriate. Revisions occur as a result of changes in prices, costs, fiscal regimes and reservoir performance or a change in Pengrowths plans with respect to future development or operating practices. Determination of CGUs The recoverability of development and
production asset carrying values are assessed at the CGU level. Determination of what constitutes a CGU is subject to managements judgement. The asset composition of a CGU can directly impact the recoverability of the assets included therein.
In assessing the recoverability of oil and gas properties, each CGUs carrying value is compared to its recoverable amount, defined as the greater of fair value less costs to sell and value in use. Asset Retirement Obligations Pengrowth estimates
obligations under environmental regulations in respect of decommissioning and site restoration. These obligations are determined based on the expected present value of expenses required in the process of plugging and abandoning wells, dismantling of
wellheads, production and transportation facilities and restoration of producing areas in accordance with relevant legislation, discounted from the date when expenses are expected to be incurred. Most of the abandonment of future expenses, estimated
logistics of performing abandonment work and the discount rate used to calculate the present value of future expenses would have a significant effect on the carrying amount of the decommissioning provision. Impairment testing The impairment testing of PP&E is
completed at least annually for each CGU, and is based on estimates of proved plus probable reserves, production rates, oil and natural gas prices, future costs, discount rate and other relevant assumptions. Undeveloped land and contingent resources
are also considered. The impairment assessment of goodwill is based on the estimated fair value of Pengrowths CGUs. By their nature, these estimates are subject to measurement uncertainty and may impact the financial statements of future
periods.

Valuation of trade and other receivables, and prepayments to suppliers Management estimates the likelihood of the collection of trade and other receivables and recovery of prepayments based on an analysis of individual accounts.
Factors taken into consideration include the aging of receivables in comparison with the credit terms allowed to customers and the financial position and collection history with the customer. Should actual collections be less than estimates,
Pengrowth would be required to record an additional expense. NET INCOME PER SHARE Basic net income per share is calculated using the weighted average number of shares outstanding for the year. Diluted net income per share amounts includes the
dilutive effect of common share rights and options, deferred entitlement share units and other share units under the new long term incentive plans using the treasury stock method. The treasury stock method assumes that any proceeds obtained on the
exercise of in-the-money share unit rights and options would be used to purchase common shares at the average trading price during the period. The
dilutive effect of convertible debentures is calculated using net income for the period, adjusted for the after tax interest on the convertible debentures assuming they were converted at the start of the period; and adding to the diluted number of
shares the weighted average shares issuable if the convertible debentures were converted at the start of the period. CASH AND TERM
DEPOSITS Cash and term deposits include demand deposits and term deposits with original maturities of less than 90 days. COMPARATIVE FIGURES As required under IFRS,
changes in the accounting for the NAL Acquisition that arose in the fourth quarter of 2012 were adjusted retrospective to the second quarter of 2012.  3.
RECENT ACCOUNTING PRONOUNCEMENTS Accounting Policies
adopted January 1, 2013 Pengrowth adopted IFRS 10 Consolidated Financial Statements, IFRS 11 Joint Arrangements, IFRS 12 Disclosures of
Interests in Other Entities, as well as the consequential amendments to IAS 28 Investments in Associates and Joint Ventures (2011) and IFRS 13 Fair Value Measurement, with a date of initial application of January 1, 2013. The adoption of these standards on January 1, 2013 will have no impact on the amounts recorded in the Corporations Consolidated Financial Statements. IFRS 10: Consolidated Financial Statements (IFRS 10) IFRS 10 introduces a new control model that is applicable to all investees; among other things, it requires the consolidation of an investee if the Corporation controls the investee on the basis of de facto
circumstances. Subsidiaries are entities controlled by the Corporation. The Corporation controls an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns
through its power over the entity. The financial statements of subsidiaries are included in the Consolidated Financial Statements from the date that control commences until the date that control ceases. On January 1, 2013, the Corporation had wholly owned subsidiaries, none of which hold any significant assets (holding companies). The determination of whether
to consolidate these entities does not involve any significant judgments or assumptions. There are no significant restrictions on the ability of the Corporation to access or use the assets, and settle the liabilities of the Corporation and its
subsidiaries except for customary limitations in the Corporations credit facility (i.e. notification of significant dispositions). IFRS 11:
Joint Arrangements (IFRS 11) Joint arrangements are arrangements of which the Corporation has joint control, established by contracts
requiring unanimous consent for decisions about the activities that significantly affect the arrangements returns. Under IFRS 11, joint arrangements are classified as either joint operations or joint ventures depending on the
Corporations rights to the assets and obligations for the liabilities of the arrangements. When making this assessment, the Corporation considers the structure of the arrangements, the legal form of any separate vehicles, the contractual terms
of the arrangement and other facts and circumstances. Previously, the structure of the arrangement was the sole focus of classification.

##### Table of Contents

The Corporation has no joint arrangements under IFRS 11. A significant portion of the Corporations oil and
gas activities are conducted with others, however, these are considered jointly controlled assets and are outside the scope of IFRS 11. These Consolidated Financial Statements reflect only the Corporations proportionate share of the related
assets, obligations, revenue and expenses of jointly controlled assets. IFRS 12: Disclosures of Interests in Other Entities (IFRS 12) IFRS 12 sets out certain disclosures that are required relating to interests in subsidiaries, associates, joint arrangements and unconsolidated
structured entities. The Corporation does not have any investments that are not consolidated nor has it entered into any joint arrangements or structured entities. IFRS 13: Fair Value Measurement (IFRS 13) IFRS 13 defines fair value, sets out a single standard
framework for measuring fair value and the required disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market
participants at the measurement date. IFRS 13 is applied prospectively to fair value measurements occurring on or after January 1, 2013. The
additional disclosure requirements of IFRS 13 are also applied prospectively and will be presented, as relevant, in the 2013 interim and annual financial statements. Accounting policies not yet adopted IFRS 9: Financial Instruments (IFRS 9) IFRS 9 is expected to be published in three parts. The first part, Phase 1  classification and measurement of financial instruments (IFRS 9, Phase 1), was published in October 2010. IFRS 9, Phase
1, sets out the requirements for recognizing and measuring financial assets, financial liabilities and some contracts to buy or sell non-financial items. IFRS 9, Phase 1 simplifies measurement of financial assets by classifying all financial assets
as those being recorded at amortized cost or being recorded at fair value. For financial assets recorded at fair value, any change in the fair value would be recognized in net income. IFRS 9, Phase 1, is required to be adopted for years beginning on
or after January 1, 2015 although earlier adoption is allowed. Pengrowth has not made any decision as to early adoption and based on a preliminary assessment this standard should not have a material impact on Pengrowth. Amendments to IAS 32 Financial Instruments: Presentation (IAS 32) and IFRS 7: Financial Instruments: Disclosures (IFRS 7) Offsetting Financial Assets and Financial Liabilities: Amendments to IAS 32 and IFRS 7, was published in December 2011. The amendments to IAS 32
clarify the requirements for offsetting financial instruments. The amendments to IFRS 7 introduce new disclosure requirements for financial assets and financial liabilities that are offset in the Consolidated Balance Sheets, or are subject to
enforceable master netting arrangements or similar agreements. The amendment to IFRS 7 is applied retrospectively for annual periods beginning on or
after January 1, 2013, while amendments to IAS 32 is applied retrospectively for annual periods beginning on or after January 1, 2014. Pengrowth has not made any decision as to early adoption of IAS 32 and it is expected that these
standards will not have a material impact on Pengrowth.  4.
BUSINESS COMBINATIONS NAL ENERGY CORPORATION Pengrowth and NAL Energy Corporation (NAL)
completed a business combination on May 31, 2012 (the Combination) where Pengrowth acquired all of the outstanding common shares of NAL
in exchange for 0.86 of a Pengrowth share per NAL share. The Combination resulted in the issuance of 131.2 million common shares of Pengrowth to former NAL shareholders, as well as the assumption by Pengrowth of NALs convertible
debentures and long term debt. Pengrowths share price on the date that the transaction was announced on March 22, 2012, was $9.95 per share. The share price on the closing date, which is the price Pengrowth is required to use to value the
shares issued in the Combination, was $7.36 per Pengrowth share. NAL was a publicly traded petroleum and natural gas company with operations in
Alberta, British Columbia, Saskatchewan and Ontario. Pengrowth acquired NAL to enable growth opportunities that result from a larger, stronger and more diverse company through enhanced exposure to light oil plays.

)Gain on acquisition


(73,538
)$
965,721 The estimated fair value of property, plant and equipment was determined using both internal estimates and an independent reserve
evaluation. The deferred tax liability was determined based on applying Pengrowths effective deferred income tax rate of approximately 25 percent to the difference between the book and tax basis of the net assets acquired. The asset retirement
obligation was determined using Pengrowths estimated timing and costs to remediate, reclaim and abandon the wells and facilities. An inflation rate of 2 percent and a discount rate of 8 percent were used. The gain on acquisition amounted to $73.5 million and is recorded as a separate line item on the Consolidated Statements of Income. The gain is due in large part
to a decline in Pengrowths share price from the date the transaction was announced to the closing date, and has no basis for tax purposes. As part of finalizing certain balances, Pengrowth decreased the previously recorded working capital
deficiency by $5.7 million resulting in an adjustment to the gain on acquisition which will be reflected in the second quarter of 2012 comparative figures. The fair value of receivables included in the working capital deficiency was $44.2 million. The Consolidated Financial Statements include the results of operations and cash flows from NAL subsequent to the closing date of May 31, 2012.
Proforma revenues net of royalties and net income for the combined entity for the period January 1, 2012 to December 31, 2012 would have been approximately $1.4 billion and $13.0 million, respectively. Revenue net of royalties contributed by NAL since the acquisition for the period June 1, 2012 to December 31, 2012 was $201.9 million. Net income
contributed by NAL in this period is not determinable, as the results of NALs operations were combined effective June 1, 2012. Transaction costs relating to the business combination in the amount of $21.5 million were incurred by
Pengrowth to December 31, 2012, and are included in the other (income) expense line in the Consolidated Statements of Income. For the period from
closing on May 31, 2012 to August 31, 2012, certain administrative functions affecting the acquired NAL properties were transferred from the former administrating management company (the
Manager) to Pengrowth. In this transition period, Pengrowth paid its portion of the Managers general and administrative costs, as
determined by NALs share of production under management. LOCHEND CARDIUM Pengrowth purchased properties in the Lochend Cardium area of Alberta on November 2, 2012 for $61.4 million adding approximately 530 boe/d with more optimization of this production expected in early 2013. The
assets acquired complement and consolidate Pengrowths position in this light oil resource play. The transaction was accounted for by the
acquisition method based on fair values as follows:  Acquired net assets:Property, plant and equipment

$
61,805Asset retirement obligation


(366
)$
61,439 The estimated fair value of property, plant and equipment was determined using internal estimates. The asset retirement obligation
was determined using Pengrowths estimated timing and costs to remediate, reclaim and abandon the wells and facilities. An inflation rate of 1.5 percent and a discount rate of 8 percent were used.

84,712 REMEDIATION TRUST FUNDS Pengrowth has a contractual obligation to make contributions to a remediation trust fund that is used to cover certain ARO on its Judy Creek properties in the Swan Hills area. Pengrowth makes monthly
contributions to the fund of $0.10/boe of production from the Judy Creek properties and an annual lump sum contribution of $250,000. The investment in the Judy Creek remediation trust fund is classified as fair value through profit or loss. Interest
income is recognized when earned and included in other (income) expense. As at December 31, 2012 the carrying value of the Judy Creek remediation trust fund was $7.5 million (December 31, 2011  $8.2 million). Pengrowth has a contractual obligation to make contributions to a remediation trust fund that will be used to fund the ARO of the SOEP properties and facilities.
Pengrowth currently makes a monthly contribution to the fund of $0.52/MMBtu of its share of natural gas production and $1.04/bbl of its share of natural gas liquids production from SOEP. The investment in the SOEP fund is classified as fair value
through profit or loss. Investment income is recognized when earned and is recorded in other (income) expense. As at December 31, 2012 the carrying value of the SOEP remediation trust fund was $46.3 million (December 31, 2011  $41.5
million). The following reconciles Pengrowths investment in remediation trust funds for the periods noted below:  Remediation Trust FundsBalance, January 1, 2011

53,806 OTHER INVESTMENT Pengrowth owns 1.0 million shares of a private corporation with an estimated fair value of $20 million. This investment is classified as fair value through
profit or loss. The fair value is based in part on recent trading activity in the private company. Pengrowth owns a minority interest in and does not have significant influence over the private corporation. As the company is private, the estimated fair value is not based on observable market data and there are restrictions on selling the shares. Therefore, it is
uncertain if Pengrowth could realize this value in an open market and, as such, the fair value is subject to revision. The fair value has decreased to $20 million as at December 31, 2012 (December 31, 2011  $35 million), resulting in an
unrealized loss of $15 million for the year ended December 31, 2012 (December 31, 2011  $23 million gain).

recorded on divestitures (December 31, 2011  $12.6 million). ASSETS HELD FOR SALE During the fourth quarter of 2012, Pengrowth announced that it had an agreement in place to sell its 10.01952 percent working interest in its non-operated Weyburn
property. Total proceeds, prior to closing adjustments, will be $315 million. The sale is expected to close in early March 2013.

##### Table of Contents

The $317.3 million carrying value of the Weyburn properties is presented as assets held for sale and classified
as current assets on the Consolidated Balance Sheets. The related ARO liability of $3.4 million is presented as liabilities associated with assets held for sale and classified as current liabilities on the Consolidated Balance Sheets. IMPAIRMENT TESTING IFRS requires an impairment
test to assess the recoverable value of the PP&E within each CGU whenever there is an indication of impairment. Impairment tests were performed at December 31, 2011, June 30, 2012 and December 31, 2012. The recoverable
amounts of each CGU was based on the higher of value in use or fair value less costs to sell. The estimates of the recoverable amounts were determined
based on the following information:  (a)
The net present value of the CGUs oil and gas reserves using;  i.
Proved plus probable reserves as estimated by Pengrowths independent reserves evaluator,  ii.
The commodity price forecast of Pengrowths independent reserves evaluator,  iii.
Discounted at an estimated market rate.  (b)
The fair value of undeveloped land.  (c)
The fair value of contingent resources estimated by Management and Pengrowths independent reserves evaluator. Key input estimates used in the determination of cash flows from oil and gas reserves include the following:  (a)
Reserves. Assumptions that are valid at the time of reserve estimation may change significantly when new information becomes available. Changes in forward price estimates,
production costs or recovery rates may change the economic status of reserves and may ultimately result in reserves being restated.  (b)
Oil and natural gas prices. Forward price estimates for oil and natural gas are used in the cash flow model. Commodity prices have fluctuated widely in recent years due to
global and regional factors including supply and demand fundamentals, inventory levels, exchange rates, weather, economic and geopolitical factors.  (c)
Discount rate. The discount rate used to calculate the net present value of cash flows is based on estimates of an approximate cost of capital for potential acquirers of
Pengrowth or Pengrowths CGUs. Changes in the general economic environment could result in significant changes to this estimate.  (d)
Undeveloped land. The undeveloped land value is based on Pengrowths undeveloped land acreage and the current market prices for undeveloped land.  (e)
Contingent resources. Assumptions that are valid at the time of contingent resource estimation may change significantly when new information becomes available. Changes in
forward price estimates, production costs or recovery rates may change the economic status of contingent resources and may ultimately result in contingent resources being restated. The impairment tests carried out were based on a discount rate of 8 percent, and an inflation rate of 2 percent.

##### Table of Contents

Based on the impairment tests carried out, there were no additional impairments to record at December 31,
2012. The impairment test is sensitive to lower commodity prices, which have been under significant downward pressure in recent periods, particularly natural gas prices. Further declines in commodity prices in 2013 could result in additional
impairment charges as the cushions in the CGU impairment tests have been eroded by price decreases. At June 30 2012, the carrying value of the
producing Groundbirch CGU exceeded the fair value less costs to sell and an impairment of $30.0 million on PP&E was recognized. At
December 31, 2011, the carrying value of the producing Groundbirch CGU exceeded the fair value less costs to sell and an impairment was recognized for $27.4 million. As a result, the full amount of goodwill attributed to the producing
Groundbirch CGU was eliminated, thereby reducing goodwill by $16.2 million. The related PP&E was reduced by $11.1 million. The impairments noted
above may be reversed if the fair value of the producing Groundbirch CGU increases in future periods; however the impairment of goodwill attributed to the producing Groundbirch CGU cannot be reversed.  7.

563,663 E&E assets consist of Pengrowths exploration and development projects which are pending the determination of proved plus
probable reserves and production. Additions represent Pengrowths share of costs incurred on E&E assets during the period. E&E assets consist mainly of costs associated with the Lindbergh project and the undeveloped portion of
Groundbirch. Upon achievement of commercial viability and technical feasibility, E&E assets are transferred to property, plant and equipment. There were no amounts transferred to property, plant and equipment during the year ended December 31, 2012. During 2011, the amounts transferred
related to the producing sections of the Grounbirch property. During 2012, the Lindbergh project remained in E&E as Pengrowth worked on achieving technical feasibility and demonstrating commercial viability, including receiving all of the
necessary environmental and regulatory approvals. Thus, all production from the Lindbergh pilot project was not included in production volumes and any net revenue received from production was not recognized in income while the project remained
classified as an E&E Asset. During the year ended December 31, 2012, the revenues, net of royalties and production costs, capitalized to the Lindbergh pilot project were $4.9 million (December 31, 2011  nil). Subsequent to December 31, 2012, the Board of Directors sanctioned the first 12,500 bbl/d of the Lindbergh project. During the year ended December 31, 2012, $1.5 million (December 31, 2011  $1.6 million) of directly attributable general and administrative costs
related to exploration and evaluation activities were capitalized. IMPAIRMENT OF E&E ASSETS During the second quarter of 2012, it was determined that there will be no future drilling in the Horn River area due to low natural gas prices and a lack of
infrastructure. Accordingly, there will be no additional capital spent to hold Pengrowths existing leases in the area, the majority which will now be left to expire. As a result, the carrying value of the Horn River assets was written
down to nil, resulting in an impairment of $48.3 million on E&E assets at June 30, 2012. Subsequent to June 30, 2012 there have been no
indications of impairment requiring Pengrowth to perform an impairment test.

)Balance, December 31, 2011

$
700,652Balance, December 31, 2012

$
700,652 Goodwill is stated at cost less accumulated impairment. Goodwill is assessed for impairment at each year end, or when there is an
indication of impairment, in conjunction with the assessment for impairment of PP&E. At December 31, 2012 an impairment test was performed, with no impairments to goodwill recorded. At December 31, 2011 the carrying value of the
Groundbirch CGU exceeded the fair value less costs to sell, and an impairment was recognized for $27.4 million. As a result, goodwill attributed to the Groundbirch CGU was reduced by $16.2 million to NIL and the corresponding PP&E was reduced by
$11.1 million. The impairment of goodwill attributed to Groundbirch cannot be reversed. The carrying value of goodwill at December 31, 2012 is
$701 million. Approximately $130 million is attributable to the Swan Hills area CGU as it relates directly to the purchase of the Carson Creek property in 2006. The remaining goodwill is not attributed to any specific CGU thus this value is
supported by the excess recoverable amount over the carrying value of certain of Pengrowths CGUs.  9.
CONVERTIBLE DEBENTURES In connection with the business
combination with NAL, Pengrowth assumed $349 million of subordinated convertible debentures, which were issued in three different series. These debentures are unsecured, and pay interest in arrears on a semi-annual basis. Each $1,000
debenture is convertible at the option of the holder at any time into fully paid common shares at a pre-determined conversion price per common share. Pengrowth was required to make offers to purchase all of the outstanding NAL 6.75 percent Debentures and NAL 6.25 percent Series A Debentures at a price equal to
101 percent of the respective principal amounts plus accrued and unpaid interest, and all of the outstanding NAL 6.25 percent Series B Debentures at a price equal to 100 percent of the principal amount thereof plus accrued and unpaid interest. As a
result, on June 22, 2012, Pengrowth purchased $50.5 million of debenture principal for $52.1 million, which included accrued interest of $0.9 million and a premium of $0.7 million. The convertible debentures are classified as a non-current liability on the Consolidated Balance Sheets and the debt premium accretes over time to the principal amount owing on maturity. No value has been ascribed
to equity (through the conversion feature), as a result of Pengrowths ability to borrow at a lower rate than the convertible debenture interest rate. On August 31, 2012, $59.5 million of debentures matured and were settled in cash, leaving two series outstanding at December 31, 2012. The following table summarizes each series as well as the activity
associated with the convertible debentures from the date of acquisition to December 31, 2012:  Series

1,007,686 Pengrowths unsecured covenant based revolving credit facility includes a committed value of $1 billion and a $250 million
expansion feature, providing $1.25 billion of credit capacity from a syndicate of seven Canadian and three foreign banks. The facility matures on November 29, 2015 and can be renewed at Pengrowths discretion any time prior to its
maturity, subject to syndicate approval. In the event that the lenders do not agree to a renewal, the outstanding balance is due upon maturity. This
facility carries floating interest rates that are expected to range between 2.0 percent and 3.25 percent over bankers acceptance rates, depending on Pengrowths ratio of senior debt to earnings before interest, taxes and non-cash items.
At December 31, 2012, the available facility was reduced by drawings of $160 million (December 31, 2011 - nil) and letters of credit in the amount of approximately $28 million (December 31, 2011- $24 million) were outstanding. Pengrowth also maintains a $50 million demand operating facility with one Canadian bank. At December 31, 2012, this facility was undrawn (December 31, 2011 -
nil) and reduced by approximately $0.9 million of outstanding letters of credit (December 31, 2011  $1.5 million). When utilized together with any overdraft amounts, this facility appears on the Consolidated Balance Sheets as a current
liability in bank indebtedness. As of December 31, 2012, an unrealized cumulative foreign exchange gain of $59.3 million (December 31, 2011 
$42.8 million gain) has been recognized on the U.S. dollar term notes since the date of issuance. As of December 31, 2012, an unrealized cumulative foreign exchange gain of $32.7 million (December 31, 2011 - $35.1 million gain) has been
recognized on the U.K. pound sterling denominated term notes since inception. See Note 18 for additional information about foreign exchange risk management and the impact on the Consolidated Financial Statements. The five year schedule of long term debt repayment based on current maturity dates and assuming the revolving credit facility is not renewed is as follows: 2013 -
$49.7 million, 2014 - NIL, 2015 - $311.6 million, 2016 - NIL, 2017- $396.8 million.

3,525,222 DIVIDEND REINVESTMENT PLAN Pengrowths Dividend Reinvestment Plan (DRIP) entitles shareholders to reinvest cash dividends in
additional shares of Pengrowth. Under the DRIP, the shares are issued from treasury at a 5 percent discount to the weighted average closing price as determined by the plan. On January 3, 2012, Pengrowth announced that it had introduced a Premium Dividend program. The Premium Dividend program was suspended effective December 17, 2012.

SHARE BASED COMPENSATION PLANS Pengrowths Long Term
Incentive Plan (LTIP) as described below is used to grant awards of share based compensation. Prior to January 1, 2011, Pengrowth had
other long term incentive plans that are being phased out with no new awards to be issued under the previous long term incentive plans. A rolling
maximum of 4.5 percent of the issued and outstanding common shares may be reserved for issuance under all share based compensation plans in the aggregate, as approved by shareholders. As at December 31, 2012, the number of shares issuable under
the share based compensation plans, in aggregate, represents 1.2 percent of the issued and outstanding common shares, which is within the limit. Share
based compensation expense is composed of the following:  Year ended December 312012

These compensation plans were used while Pengrowth was a trust. Effective January 1, 2011, no further grants were made under these plans. LONG TERM INCENTIVE PLAN (LTIP) Pengrowths LTIP has the following components:  (a)
Performance Share Units (PSUs) PSUs entitle the holder to a number of common shares to be issued in the third year after
grant. PSUs may be awarded to employees, officers and consultants. Shares issued in 2011 will be subject to a performance factor ranging from 50 percent to 200 percent of the number of shares granted plus the amount of reinvested notional dividends,
while shares issued in 2012 will be subject to a performance factor ranging from 50 percent to 150 percent of the number of shares granted plus the amount of reinvested notional dividends.  (b)
Restricted Share Units (RSUs) RSUs may be awarded to employees, officers and consultants and entitle the holder to a number
of common shares plus reinvested notional dividends to be issued at vesting over three years. The RSUs generally vest on the first, second and third anniversary date from the date of grant.  (c)
Deferred Share Units (DSUs) DSUs are currently only issued to members of the Board of Directors. Each DSU entitles the
holder to one common share plus reinvested notional dividends since the grant date of the DSU. The DSUs vest upon grant but can only be converted to common shares upon the holder ceasing to be a Director of Pengrowth. The number of common shares
ultimately issued will be equal to the number of DSUs initially granted to the holder plus the amount of reinvested notional dividends accruing during the term of the DSUs. The Board of Directors retain discretion with respect to the LTIP.

Weighted average deemed DRIP price for accounting purposes is based on the average of the original grant prices. Compensation expense related to PSU, RSU, and DSU plans are based on the fair value of the share units at the date of grant. The fair value of the performance
related share units is determined at the date of grant using the closing share price and is adjusted for the estimated performance multiplier. The amount of compensation expense is reduced by an estimated forfeiture rate at the date of grant, which
has been estimated at 10 to 25 percent for employees and 3 to 15 percent for officers, depending on the vesting period. There is no forfeiture rate applied for DSUs as they vest immediately upon grant. For the performance related share plans, the
number of shares awarded at the end of the vesting period is subject to certain performance conditions. Fluctuations in compensation expense may occur due to changes in estimating the outcome of the performance conditions. Compensation expense is
recognized in net income over the vesting period with a corresponding increase or decrease to contributed surplus. Upon the issuance of common shares at the end of the vesting period, shareholders capital is increased and contributed surplus
is decreased by the amount of compensation expense incurred during the vesting period. The shares are issued from treasury upon vesting. For the year
ended December 31, 2012, Pengrowth recorded $13.0 million of compensation expense related to the LTIP units (December 31, 2011  $7.7 million), based on the weighted average grant date fair value of $8.80 per share unit (December 31,
2011  $12.46 per share unit). As at December 31, 2012, the amount of compensation expense to be recognized over the remaining vesting period was $15.4 million or $4.46 per share unit (December 31, 2011  $8.8 million or $4.86
per share unit) subject to the determination of the performance multiplier. The unrecognized compensation cost will be expensed to net income over the remaining weighted average vesting period of 1.5 years.

##### Table of Contents

PREVIOUS LONG TERM INCENTIVE PLANS  (a)
Deferred Entitlement Share Units (DESU) Plan The DESU plan comprises of two types of awards being performance and non-performance related share units. The performance related share units issued to each
participant at the end of the three year vesting period will be subject to a performance test which compares Pengrowths three year average total return to the three year average total return of a peer group of other energy corporations such
that upon vesting, the number of shares issued from treasury may range from 0.5 to 2.0 times the total of the number of shares granted plus accrued shares through the deemed reinvestment of notional dividends. The non-performance related share units
generally vest equally over three years and entitle the holder in each vesting year to one third of the number of common shares initially granted plus the amount of any reinvested notional dividends. The following provides a continuity of the DESUs:  2012

These compensation plans were used while Pengrowth was a trust. Effective January 1, 2011, no further grants were made under these plans.  (2)
2009 DEU grant vested in March 2012 with a performance multiplier of fifty percent.  (3)
Weighted average deemed DRIP price for accounting purposes is based on the average of the original grant prices. Pengrowth recorded a recovery of compensation expense of ($0.3) million for the year ended December 31, 2012 related to the DESUs (December 31, 2011 
$3.7 million expense). The recovery in 2012 related to a change in the performance multiplier for DESUs. As at December 31, 2012, the amount of compensation expense to be recognized over the remaining vesting period was approximately $0.3
million (December 31, 2011  $3.7 million) or $0.37 per DESU (December 31, 2011  $2.21 per DESU), subject to the determination of the performance multiplier. The unrecognized compensation cost will be expensed to net income over the
remaining weighted average vesting period of 0.2 of a year (December 31, 2011  1.0 year).  (b)
Common Share Rights Incentive Plan The trust unit rights
incentive plan that was effective when Pengrowth was a trust, was renamed on conversion to the common share rights incentive plan. This plan consists of two types of awards being share unit options exercisable at a fixed price and share unit rights
exercisable at the original grant price or at a reduced price that is calculated in accordance with the plan. The common share rights incentive plan provides the holder the right to purchase common shares over a five year period. During the years
ended December 31, 2012 and 2011 there were no exercise price reductions under this plan.

debentures were excluded from the diluted net income per share calculation as their effect is anti-dilutive.  17.
CAPITAL DISCLOSURES Pengrowth defines its capital as
shareholders equity, long term debt, convertible debentures, bank indebtedness and working capital. Pengrowths goal over longer
periods is to modestly grow production and reserves on a debt adjusted per share basis. Pengrowth seeks to retain sufficient flexibility with its capital to take advantage of acquisition opportunities that may arise. Pengrowth must comply with certain financial debt covenants. Compliance with these financial covenants is closely monitored by management as part of
Pengrowths overall capital management objectives. The covenants are based on specific definitions prescribed in the debt agreements and are different between the credit facility and the term notes. Throughout the period, Pengrowth was in
compliance with all financial covenants. Management monitors capital using non-GAAP financial metrics, primarily total debt to the trailing twelve
months earnings before interest, taxes, depletion, depreciation, amortization, accretion, and other non-cash items (Adjusted EBITDA) and
total debt to total capitalization. Pengrowth seeks to manage the ratio of total debt to trailing Adjusted EBITDA and total debt to total capitalization ratio with the objective of being able to finance its growth strategy while maintaining
sufficient flexibility under the debt covenants. However, there may be instances where it would be acceptable for total debt to trailing Adjusted EBITDA to temporarily fall outside of the normal targets set by management such as financing growth
opportunities. This would be a strategic decision recommended by management and approved by the Board of Directors with steps taken in the subsequent period to restore Pengrowths capital structure based on its capital management objectives. In order to maintain its financial condition or adjust its capital structure, Pengrowth may dispose of non-core assets, adjust the level of capital
spending, issue new debt, refinance existing debt, issue additional equity, or adjust the level of dividends paid to shareholders to reduce debt levels.

FINANCIAL INSTRUMENTS AND RISK MANAGEMENT Pengrowths
financial instruments are composed of accounts receivable, accounts payable, fair value of risk management assets and liabilities, remediation trust funds, other investments in another entity, dividends payable to shareholders, bank indebtedness,
convertible debentures and long term debt. Details of Pengrowths significant accounting policies for recognition and measurement of financial
instruments are disclosed in Note 2. RISK MANAGEMENT OVERVIEW Pengrowth has exposure to certain market risks related to volatility in commodity prices, interest rates and foreign exchange rates. Derivative instruments are used to manage exposure to these risks.
Pengrowths policy is not to utilize financial instruments for trading or speculative purposes. The Board of Directors and management have overall
responsibility for the establishment of risk management strategies and objectives. Pengrowths risk management policies are established to identify the risks faced by Pengrowth, to set appropriate risk limits, and to monitor adherence to risk
limits. Risk management policies are reviewed regularly to reflect changes in market conditions and Pengrowths activities. MARKET
RISK Market risk is the risk that the fair value, or future cash flows of financial assets and liabilities, will fluctuate due to movements in market
prices. Market risk is composed of commodity price risk, foreign currency risk and interest rate risk. Commodity Price Risk Pengrowth is exposed to commodity price risk as prices for oil and gas products fluctuate in response to many factors including local and global supply and demand,
weather patterns, pipeline transportation, political stability and economic factors. Commodity price fluctuations are an inherent part of the oil and gas business. While Pengrowth does not consider it prudent to entirely eliminate this risk, it does
mitigate some of the exposure to commodity price risk to protect the return on acquisitions and provide a level of stability to operating cash flow which enables Pengrowth to fund its capital development program and dividends. Pengrowth utilizes
financial contracts to fix the commodity price associated with a portion of its future production. The use of forward and futures contracts are governed by formal policies and is subject to limits established by the Board of Directors. The Board of
Directors and management may re-evaluate these limits as needed in response to specific events such as market activity, additional leverage, acquisitions or other transactions where Pengrowths capital structure may be subject to more risk from
commodity prices.

Cdn Commodity Price Sensitivity Each Cdn $1/barrel change in future oil prices would result in approximately Cdn $6.5 million pre-tax change in the unrealized gain (loss) on commodity risk
management contracts as at December 31, 2012 (December 31, 2011  Cdn $7.5 million). Similarly, each Cdn $0.25 /MMBtu change in future natural gas prices would result in approximately Cdn $17.3 million pre-tax change in the unrealized gain
(loss) on commodity risk management contracts (December 31, 2011  Cdn $1.3 million). As at close December 31, 2012, the AECO gas spot price
was $3.04/MMBtu (December 31, 2011  $2.61/MMBtu), the WTI prompt monthly price was U.S. $91.82/barrel (December 31, 2011  U.S. $98.83 /barrel).

The average Alberta power pool price was $57.62/MWh for the month ended December 31, 2012 (December 31, 2011  $51.26/MWh). The average Alberta power pool price was $64.32/MWh for the year ended December 31, 2012 (December 31, 2011
 $76.21/MWh). Power Price Sensitivity Each Cdn $1/MWh change in future power prices would result in approximately Cdn $0.1 million pre-tax change in the unrealized gain (loss) on power risk management
contracts as at December 31, 2012 (December 31, 2011  Cdn $0.2 million). Foreign Exchange Risk Pengrowth is exposed to foreign currency fluctuations as crude oil and natural gas prices received are referenced to U.S. dollar denominated prices. Pengrowth has
mitigated some of this exchange risk by entering into fixed Canadian dollar crude oil and natural gas price swaps as outlined in the commodity price risk section above. Pengrowth is exposed to foreign currency fluctuation on the U.S. dollar and U.K. pound sterling denominated notes for both interest and principal payments. Pengrowth has mitigated some of this risk by entering into
a series of swap contracts and other derivatives in order to fix the foreign exchange rate on a portion of the U.S. dollar and all of the U.K. pound sterling denominated notes. Foreign Exchange Contracts U.K. Pound Sterling Denominated Term Debt Pengrowth entered into foreign exchange risk management contracts when it issued the U.K. pound sterling term notes. These contracts fix the Canadian dollar to the
U.K. pound sterling exchange rate on the interest and principal of the U.K. pound sterling denominated debt. Pengrowth has two U.K. pound sterling note issuances outstanding. The 50 million U.K. pound sterling debt was issued in 2005 and
is due December 2015. The 15 million U.K. pound sterling debt was issued in 2012 and is due October 2019. The exchange rate per Canadian dollar is fixed at 0.4976 on the 50 million U.K. pound sterling debt, and 0.63 on the 15 million
U.K. pound sterling debt. U.S. Denominated Term Debt A series of swap contracts were transacted in order to fix the foreign exchange rate on a portion of Pengrowths U.S. dollar denominated term debt. Each swap requires Pengrowth to buy U.S. dollars at a
predetermined rate and time based upon the maturity dates of the U.S. denominated term debt.  Swaps-Buy U.S. dollarsContract Type

Interest Rate Contracts The following interest rate swap contracts were outstanding at December 31, 2012. These contracts reduce exposure to rising interest rates by fixing the interest rate on floating rate debt. Under the
contracts, Pengrowth pays the fixed interest rate, and receives the floating interest rate on the notional amounts. The floating interest rate received is the three-month Bankers Acceptance CDOR
(Canadian Depository Offered Rate).  Remaining Term

2.0% Interest Rate Sensitivity Interest Rate Contracts As at December 31, 2012, if
interest rates had been 1 percent lower, with all other variables held constant, net income for the year would have been $0.3 million lower pre-tax (2011  nil), due to the change in fair value of the derivatives contracts. An equal and
opposite effect would have occurred to net income had interest rates been 1 percent higher. Bank Interest Cost As at December 31, 2012, Pengrowth had approximately $1.5 billion of current and non-current long term debt outstanding (December 31, 2011  $1.0 billion)
of which $160 million was based on floating interest rates (December 31, 2011  nil). A 1 percent increase in interest rates would increase pre-tax interest expense by approximately $1.6 million for the year ended December 31, 2012 (2011
 nil). Summary of Gains and Losses on Risk Management Contracts Pengrowths risk management contracts are recorded on the Consolidated Balance Sheets at their estimated fair value and split between current and non-current assets and liabilities on a contract by contract
bases. Realized and unrealized gains and losses are included in the Consolidated Statements of Income. The following tables provide details of the fair

accounts payable, bank indebtedness, and dividends payable approximate their carrying amount due to the short-term nature of those instruments. The fair value of the Canadian dollar revolving credit facility is equal to its carrying amount as the
facility bears interest at floating rates and credit spreads within the facility are indicative of market rates. The fair value of the remediation trust funds and minority investment in a private company are equal to their carrying amount as these
assets are carried at their estimated fair value. The following tables provide fair value measurement information for financial assets and liabilities

 Level 1 Fair Value Measurements Financial assets and liabilities are recorded at fair value based on quoted prices in active markets. Level 2
Fair Value Measurements Risk management contracts  the fair value of the risk management contracts is based on commodity and foreign exchange
curves that are readily available or, in their absence, third-party market indications and forecasts priced on the last trading day of the applicable period. Derivative contracts are recorded at fair value on the Consolidated Balance Sheets as current or long-term assets or liabilities, based on their values on a contract-by-contract basis. The derivative contracts fair
values are all considered level two under the fair value hierarchy. Term notes  the fair value of the term notes is determined based on the risk
free interest rate on government debt instruments of similar maturities, adjusted for estimated credit risk, industry risk and market risk premiums. Level 3 Fair Value Measurements Investment in Private
Corporation  the fair value of the investment in Private Corporation is determined by considering several factors, including recent trading activity in the Private Corporation. The fair value of the investment has decreased to $20 million as
at December 31, 2012 (December 31, 2011  $35 million), resulting in an unrealized loss of $15 million in 2012 (December 31, 2011  gain of $23 million). CREDIT RISK Credit risk is the risk of financial loss to Pengrowth if a counterparty to a financial
instrument fails to meet its contractual obligations. A significant portion of Pengrowths accounts receivable are with customers in the oil and gas industry and are subject to normal industry credit risks. Uncertainty in the credit markets,
should it exist, may restrict the ability of Pengrowths normal business counterparties to meet their obligations to Pengrowth. Additional credit risk could exist where little or none previously existed. Pengrowth manages its credit risk by
performing a credit review on each marketing counterparty and following a credit practice that limits transactions according to the counterpartys credit rating as assessed by Pengrowth. In addition, Pengrowth may require letters of credit or
parental guarantees from certain counterparties to mitigate some of the credit risk associated with the amounts owing by the counterparty. The use of financial swap agreements involves a degree of credit risk that Pengrowth manages through its
credit policies which are designed to limit eligible counterparties to those with investment grade credit ratings or better. The carrying value of accounts receivable and risk management assets represents Pengrowths maximum
credit exposure. Pengrowth sells a significant portion of its oil and gas to a limited number of counterparties. Pengrowth has three
counterparties that individually account for more than ten percent of annual revenue. All of these counterparties are large, well-established companies supported by investment grade credit ratings.

Pengrowth considers amounts over 90 days as past due. As at December 31, 2012, the amount of accounts
receivable that were past due was not significant. Pengrowth has not recorded a significant allowance for doubtful accounts during 2012 and 2011 and has no significant bad debt provision at December 31, 2012. Pengrowths objectives,
processes and policies for managing credit risk have not changed from the previous year. The components of accounts receivable are as follows:  As atDecember 31, 2012

183,814 LIQUIDITY RISK Liquidity risk is the risk that Pengrowth will not be able to meet its financial obligations as they fall due. Pengrowths approach to managing liquidity is to
ensure, as much as possible, that it will always have sufficient liquidity to meet its liabilities when due, under normal and stressed conditions. Management closely monitors cash flow requirements to ensure that it has sufficient cash on demand or
borrowing capacity to meet operational and financial obligations over the next three years. Pengrowth maintains a committed $1 billion term credit facility with an additional $250 million available under an expansion feature subject to lender
approval and a $50 million demand operating line of credit. Pengrowths long term notes and bank credit facilities are unsecured and equally ranked. All of Pengrowths financial liabilities are current and due within one year, except as follows:  As at December 31, 2012

SUPPLEMENTAL UNAUDITED DISCLOSURES

ABOUT OIL AND GAS PRODUCING
ACTIVITIES REQUIRED UNDER UNITED STATES GENERALLY ACCEPTED

ACCOUNTING PRINCIPLES

##### Table of Contents

SUPPLEMENTAL INFORMATION  OIL AND GAS PRODUCING ACTIVITIES

(unaudited)

The following are
supplementary oil and gas disclosures required as a result of Pengrowth being a SEC registrant. All amounts pertain to Pengrowths audited annual financial statements prepared in accordance with International Financial Reporting Standards
(IFRS). All amounts are in thousands of Canadian dollars unless otherwise noted.

OIL AND GAS RESERVES

Users of this information should be aware that the process of estimating quantities of proved and proved developed crude oil and
natural gas reserves is very complex, requiring significant subjective decisions in the evaluation of all available geological, engineering and economic data for each reservoir. The data for a given reservoir may also change substantially over time
as a result of numerous factors including, but not limited to, additional development activity, evolving production history, and continual reassessment of the viability of production under varying economic conditions. Consequently, material
revisions to existing reserve estimates occur from time to time. Although every reasonable effort is made to ensure that reserve estimates reported represent the most accurate assessments possible, the significance of the subjective decisions
required and variances in available data for various reservoirs make these estimates generally less precise than other estimates presented in connection with financial statement disclosures.

Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a
given date forward, from known reservoirs, and under existing economic conditions, operating methods and government regulations.

Proved
developed oil and gas reserves are reserves that can be expected to be recovered through existing wells with existing equipment and operating methods.

Canadian provincial royalties are determined based on a graduated percentage scale which varies with prices and production volumes. Canadian reserves, as presented on a net basis, assume royalty rates in
existence at the time the estimates were made, Pengrowths estimated future production volumes and SEC Modernization of Oil and Gas Reporting rules, using the average of the first-day-of-the-month prices for the prior 12 month period. This same
12 month average price is also used in calculating the aggregate amount of (and changes in) future cash inflows related to the standardized measure of discounted future net cash flows. The unaudited supplemental information on oil and gas
exploration and production activities for 2012 and 2011 has been presented in accordance with the SEC Modernization of Oil and Gas Reporting reserve estimation and disclosure rules. Future fluctuations in prices, production rates, or changes in
political or regulatory environments could cause the Corporations share of future production from Canadian reserves to be materially different from that presented.

Subsequent to December 31, 2012, no major discovery or other favorable or adverse event is believed to have caused a material change in the estimates of proved or proved developed reserves as of that
date.

Acquisition costs include costs incurred to purchase, lease, or otherwise acquire oil and gas properties.

Development and exploration costs include the costs for drilling and equipping development and exploratory wells, constructing facilities to extract,
treat, gather and store oil and gas. Development costs also include capitalized costs associated with additions to asset retirement obligations.

Injectants (mostly ethane and methane) are used in miscible flood programs to stimulate incremental oil recovery. The cost of injectants purchased from third parties for miscible flood projects is
deferred and amortized over the period of expected future economic benefit which is estimated to be 24 months.

Pengrowth capitalizes a
portion of general and administrative costs associated with exploration and development activities.

Approximately $564 million (2011 
$564 million) of capitalized costs to acquire and evaluate unproven and development properties has been excluded from depletion.

Notes:



|1. | Net after royalty reserves are Pengrowths lessor royalty, overriding royalty, and working interest share of the gross remaining reserves, after deduction of any
crown, freehold and overriding royalties. Crown royalties are subject to change by legislation or regulation and vary depending on production rates, selling prices and potential timing of initial production.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2. | Reserves are the estimated quantities of crude oil, natural gas and related substances anticipated from geological and engineering data to be recoverable from known
accumulations, from a given date forward, by known technology, under existing operating conditions and the average of the commodity prices on the first day of each month for the year ended December 31, 2012 and 2011.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3. | Proved oil and gas reserves are the estimated quantities of crude oil, natural gas and natural gas liquids which geological and engineering data demonstrate with
reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4. | Proved developed oil and gas reserves are reserves that can be expected to be recovered through existing wells with existing equipment and operating methods. Proved
undeveloped reserves are reserves that are expected to be recovered from known accumulations where a significant expenditure is required.

##### Table of Contents

STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO PROVED OIL AND GAS RESERVES

The following information is based on crude oil and natural gas reserve and production volumes estimated by the independent engineering
consultants of Pengrowth. It may be useful for certain comparison purposes, but should not be solely relied upon in evaluating Pengrowth or its performance. Further, information contained in the following table should not be considered as
representative of realistic assessments of future cash flows, nor should the Standardized Measure of Discounted Future Net Cash Flows be viewed as representative of the current value of Pengrowths reserves.

The future cash flows presented below are based on cost rates, and statutory income tax rates in existence as of the date of the projections and the
average of commodity prices in effect on the first day of each month for the year ended December 31, 2012 and December 31, 2011. It is expected that revisions to some estimates of crude oil and natural gas reserves may occur in the future,
due to development and production of the reserves that may occur in periods other than those assumed, and actual prices realized and costs incurred may vary significantly from those used.

Management does not rely upon the following information in making investment and operating decisions. Such decisions are based upon a wide range of factors, including estimates of probable as well as
proved reserves, and varying price and cost assumptions considered more representative of a range of possible economic conditions that may be anticipated.

The computation of the standardized measure of discounted future net cash flows relating to proved oil and gas reserves at December 31, 2012 was based on the following average of the
first-day-of-the-month benchmark prices for the twelve month period before the end of the year: Edmonton par crude oil price of $87.85/bbl (2011 - $97.03/bbl) and AECO natural gas price of $2.33/MMBtu (2011 - $3.78/MMBtu).

STANDARDIZED MEASURE OF DISCOUNTED FUTURE CASH FLOW RELATING TO PROVED OIL AND GAS RESERVES

The following table sets forth the standardized measure of discounted future net cash flows from projected production of Pengrowths crude oil and
natural gas reserves at December 31, for the years presented.

APPLICATION

Unless expressly provided herein to the contrary, this Code of Business Conduct and Ethics (the Code) applies to all directors, officers, employees, consultants and contractors (each a
Member) of Pengrowth Energy Corporation and its respective subsidiaries and affiliates (collectively, referred to herein as Pengrowth).

PURPOSE

This Code summarizes appropriate
behaviour for maintaining Pengrowths reputation for honesty and integrity earned by maintaining the highest standards of business ethics and compliance with applicable laws, rules and regulations in all our interactions with our fellow
Members, governments, local communities, securityholders, customers, suppliers, competitors and the public.

POLICY

Pengrowth and all of its Members will adhere to the highest ethical standards and compliance with laws, rules and regulations in all our business activities. Any situation, decision or response should
first consider what is right and how it reflects on Pengrowth. Although the various matters described in this Code do not cover the full spectrum of employee and contractor activities, they are indicative of the type of behaviour expected from
employees and contractors in all circumstances.

COMPLIANCE WITH
CODE

Members are expected to comply with all aspects of this Code. This Code does not specifically address every potential
form of unacceptable conduct, and it is expected that Members will exercise good judgment in compliance with the principles set out in this Code. Each Member has a duty to avoid any circumstance that would violate the letter or spirit of this Code.

COMPLIANCE WITH THE LAW

Each Member must ensure that his or her dealings and actions on behalf of Pengrowth comply with the spirit and intent of all relevant legislation, rules
and regulations including those set by a self regulatory body or professional organization of all the countries in which Pengrowth operates or where Pengrowths securities are listed on the exchanges.

HEALTH, SAFETY AND THE ENVIRONMENT

Pengrowth is committed to safe and healthful working conditions for all Members and third parties, and to conducting its activities in an
environmentally responsible manner consistent with the principles of sustainable development.

Members are expected to read, understand and
adhere to Pengrowths Environmental, Health and Safety Policies and Procedures and participate fully in this effort by improving operations to avoid injury or sickness to persons, and damage to property and the environment and by giving due
regard to all applicable safety standards, regulatory requirements, technical and conventional standards and restraints.

MAINTAINING RECORDS

Accurate, timely and reliable books of account and records are essential for
effective management to ensure

|---------------------------------------
|CODE OF BUSINESS CONDUCT AND
ETHICS|  1



---

##### Table of Contents

Pengrowth meets its business, legal and financial obligations. Members are to safeguard Pengrowths
records and adhere to retention guidelines.

ACCOUNTING AND
FINANCIAL REPORTING

Pengrowth is committed to achieving compliance with all applicable securities laws and
regulations, accounting standards, accounting controls and audit practices. Every Member is required to follow prescribed accounting and financial reporting procedures. All accounting records should accurately reflect and describe corporate
transactions and that all transactions are fairly, completely, accurately, timely and understandably accounted for and recorded in accordance with Pengrowths policies and procedures. The recording of such data must not be falsified or altered
in any way to conceal or distort assets, liabilities, revenues, expenses or the nature of the activity.

Any suspected violation relating to
accounting or financial reporting matters should be reported pursuant to procedures described in Appendix A  Complaint Procedures for Accounting, Financial Reporting and Auditing Matters and Violations of the Code of Business Conduct and
Ethics to this document.

It is essential that all Members follow established policies, procedures and internal controls. Any exception
to established policies, procedures and internal controls (excluding to this Code) is prohibited, unless appropriately authorized in advance by any officer of Pengrowth who shall report all such approved exceptions to the Audit and Risk Committee.
Exceptions to this Code are dealt with below under Exceptions.

ASSISTANCE
TO AUDITORS

No information should be concealed from the internal or external, independent auditors.

PUBLIC REPORTING

Persons responsible for the preparation of documents and reports and other public communications that Pengrowth files with, or submits to, the securities
commissions and in its other public communications to comply with its obligations under the securities laws and to meet the expectations of its securityholders and other members of the investment community, are to exercise the highest standard of
care in their preparation in accordance with the applicable laws and must include full fair, accurate, timely and understandable disclosure.

Enquiries from members of the community related to matters of a sensitive nature should be directed to a member of senior management. Any member of
senior management receiving such an enquiry is then required to refer the matter to either the President and Chief Executive Officer (the CEO), Chief Financial Officer or General Counsel whereby such senior officers will respond
on behalf of Pengrowth.

All Members responsible for disclosure are expected to read, understand, adhere to and must act according to
Pengrowths Corporate Disclosure Policy.

CONFLICT OF
INTEREST

Members must avoid interests or relationships where their personal interests may affect, or appear to affect,
their judgment in acting in the best interests of Pengrowth. This requires that each Member act in such a manner that his or her conduct will bear the closest scrutiny should circumstances demand that it be examined. Where a conflict of interest
situation may exist, or be perceived to exist, the Member may be put in a compromising position or his or her judgement may be questioned. Pengrowth wants to ensure that all Members are, and are perceived to be, free to act in the best interests of
Pengrowth.

There are many situations which can be classified as conflicts of interest, but the following examples illustrate those that are
most common.

Private Business Interest

Unless otherwise consented to by the General Counsel, a Member, either directly or indirectly through his or her immediate family or by
any other means, must not have a personal financial interest in, or place himself or



|

##### Table of Contents

herself in a position where he or she could derive a benefit or interest from, a business
transaction with Pengrowth, which financial interest or benefit is of such a nature that it would reasonably be expected to create a conflict of interest for the Member.

This, however, does not prevent a Member and his or her family from having ownership in publicly traded shares or equity in companies which may do business with Pengrowth. Nor does it prevent a consultant
or contractor from providing his or her services to Pengrowth through a third party corporation.

Involvement with Not-for-Profit Organizations

As a responsible community citizen, Pengrowth encourages and
supports Member participation in charitable, educational, cultural, political and not-for-profit organizations. Members are reminded that such participation should not be of a nature or extent that it adversely affects a Members job
performance or puts the Member in a conflict of interest position.

Outside Employment

Pengrowth recognizes that some employees may, from time to time, hold additional part-time employment outside their
employment relationship with Pengrowth. Employees are reminded that any such outside employment should not be of a nature or extent that it adversely affects the employees job performance at Pengrowth or put the employee in a conflict of
interest position. All employees who hold management positions with Pengrowth shall obtain the approval of the General Counsel before accepting any such outside employment.

Directorships

Any officer or
employee shall obtain the approval of the CEO prior to accepting a position as a director of a for-profit company or any business organization. The CEO shall obtain the approval of the Board of Directors prior to accepting a position as a director
of a for-profit company or any business organization. A director shall advise the Chairman of the Board prior to accepting a position as a director of a for-profit company or any business organization.

Related Party Transaction

In addition to the consent requirement set out under Private Business Interest above, each director and officer who is a party
to a material contract or proposed material contract with Pengrowth or is a director or an officer of or has a material interest in any entity which is a party to a material contract or proposed material contract with Pengrowth of which he has
knowledge is required to disclose in writing to the Chairman of the Board the nature and extent of the directors or officers interest. The Chairman of the Board shall make any such disclosure concerning himself to the Chair of the
Corporate Governance and Nominating Committee.

Corporate Property and Opportunities

Members are prohibited from taking for themselves, opportunities that arise through the use of corporate property,
information or position and from using corporate property, information or position for personal gain.

DISCLOSURE OF CONFLICT OF INTEREST

Disclosure of areas of potential conflict of interest will allow appropriate steps to be taken to protect the individual from these
situations.

Officers, employees, consultants and contractors are required to disclose to the appropriate Vice President in writing all
business, commercial or financial interests and activities which might reasonably be regarded as creating an actual or potential conflict with their duties of employment. Senior management will determine whether a conflict of interest does or could
exist and, if necessary, advise the person as to what steps should be taken. Directors are required to

##### Table of Contents

disclose to the Chair of the Corporate Governance and Nominating Committee (or, in the case of the Chair of
the Corporate Governance and Nominating Committee, to the other members of the Committee) all business, commercial or financial interests and activities which might reasonably be regarded as creating an actual or potential conflict with their duties
as directors.

GIFTS AND ENTERTAINMENT

The exchange of gifts and entertainment is a common practice in most business communities and is designed to develop and foster goodwill among business
partners. Accepting gifts and entertainment can cause problems when they compromise, or appear to compromise, our ability to make fair and objective business decisions. No gift or entertainment should be accepted, or offered, if it will unfairly
influence a business relationship.

There are many factors that influence whether a gift or entertainment is normal and customary. Gifts or
entertainment should be moderate, reasonable and in good taste, be of a style or value commonly accepted for business occasions and should not be unusual for the recipients job or community. The exchange must create no obligation or sense of
obligation and should occur infrequently.

Business entertainment can present situations where discretion is required since some commonly
accepted business invitations can include recreational opportunities or event tickets that are of significant value. In these cases, the recipient should ensure that there is a valid business development reason for attending. If the invitation is
for an event where the value being received may be significant, prior approval by an officer of Pengrowth is required, or in the case of the CEO, approval by the Chair of the Corporate Governance and Nominating Committee. As transportation costs for
events can also be significant, payment of these costs by another party is not acceptable and will be covered by Pengrowth if there is a valid business reason to accept the invitation.

FAIR DEALINGS

It is
Pengrowths policy to deal fairly and lawfully with all securityholders, customers, suppliers, competitors and Members. All goods and services shall be obtained on a competitive basis at the best value considering price, quality, reliability,
availability and delivery.

POLITICAL ACTIVITIES AND
CONTRIBUTIONS

Pengrowth respects and supports the right of its employees to participate in political activities. However,
these activities should not be conducted on Pengrowth time or involve the use of any Pengrowth resources. Employees will not be reimbursed for personal political contributions.

Pengrowth may occasionally express its views on local and national issues that affect its operations. In such cases, Pengrowth funds and resources may be used, but only when permitted by law and by
Pengrowths strict guidelines. On very limited occasions, Pengrowth may also make limited contributions to political parties or candidates in jurisdictions where it is legal and customary to do so. Pengrowth may pay related administrative and
solicitation costs for political action committees formed in accordance with the political laws and regulations. No employee may make or commit to political contributions on behalf of Pengrowth without the approval of the Chief Executive Officer.

CONFIDENTIAL INFORMATION

In the course of their work, Members may have access to information that is confidential, privileged, of value to competitors of Pengrowth or might be
damaging to Pengrowth if improperly disclosed. Pengrowth respects privileged business and employee related information, and therefore all Members must protect the confidentiality of such information.

USE OF CONFIDENTIAL INFORMATION

The use or disclosure of confidential information must be for Pengrowths purposes only and not for personal benefit or the benefit of others. This
applies to disclosure of confidential information concerning Pengrowth or its business activities as well as information with respect to companies having business dealings with Pengrowth. To preserve confidentiality, disclosure and discussion of
confidential information should be limited to those individuals who need to

know the information. Members are expected to read, understand and adhere to Pengrowths Corporate
Disclosure Policyand Confidentiality Agreements.

DISCLOSURE OF
CONFIDENTIAL INFORMATION

Members must guard against improper disclosure of information that may be of
competitive value to Pengrowth. Pengrowth is in a competitive environment with other companies. Certain records, reports, papers, devices, processes, plans, methods and apparatus of Pengrowth, including methods of doing business, strategies and
information on costs, prices, sales, profits, markets and opportunities are the property of Pengrowth and are considered to be confidential and proprietary. Members must not reveal such confidential information without consent of the General
Counsel.

Confidential information does not include information which is already in the public domain. Certain information may be released by
Pengrowth (to comply with securities regulations, for example) however, the release of such information is a decision of the Board of Directors and senior management. If there is any doubt as to what can or cannot be discussed outside of Pengrowth,
Members should err on the side of discretion and not communicate any information. For more specific advice, your immediate manager, the CEO, the Chief Financial Officer or General Counsel should be consulted.

These obligations regarding confidential information continue to apply to all Members following cessation of their employment or contractual relations
with Pengrowth. Members are expected to read, understand and adhere to Pengrowths Corporate Disclosure Policy and Confidentiality Agreements.

INSIDE INFORMATION

Certain
information, which Pengrowth treats as confidential, may influence the price or trading of Pengrowths common shares or other securities if it is disclosed to members of the public. Inside information would include information concerning
material exploration well results, major contracts, proposed acquisitions or mergers, and earnings figures. Members shall not use such inside information for their own financial gain or for that of their associates.

If in doubt as to the propriety of actions, the Member should seek the advice of the CEO, Chief Financial Officer or General Counsel. Members are
expected to read, understand and adhere to Pengrowths Policy on Trading in Securities.

PROTECTION AND USE OF ASSETS

All Members are responsible for protecting Pengrowths assets and their efficient use for legitimate business purposes only.
Pengrowth provides Members with computer and Internet access for work purposes. Members are expected to read, understand, acknowledge and adhere to Pengrowths Acceptable Use Policy for Information System Assets.

INTELLECTUAL PROPERTY - PATENTS, INVENTIONS,
DISCOVERIES AND COPYRIGHTS

All intellectual property including inventions, discoveries and
copyrights made by Members during or as a result of their employment or contractual relations with Pengrowth (where company time, equipment, resources or pertinent information has been used for personal gain) are the property of Pengrowth unless a
written release is obtained from the CEO.

Pengrowth and its Members honour the proprietary rights of others as expressed in patents,
copyrights, trademarks and industrial design.

EMPLOYEE RELATIONS
AND REPORTING

Pengrowth values the diversity of its Members and is committed to providing equal opportunity
in all aspect of employment. In working together, Members must ensure they treat each other with respect, dignity, honesty, fairness and provide a healthy environment that is free of harassment, offensive behaviour and discrimination.

All Members are encouraged to report any behaviour of other Members which they reasonably believe is illegal or

requirements Members are expected to read, understand and adhere to Pengrowths Delegation of Authorities guideline.

applicable law prohibit any form of retaliation for raising concerns or reporting possible misconduct in good faith or for assisting in the investigation of possible misconduct. No adverse action will be taken against any individual for making a
complaint or disclosing information in good faith. Any Member who retaliates in any way against an individual who, in good faith, reports any violation, or suspected violation, of this Code, will be subject to disciplinary action.

APPENDIX A

COMPLAINT PROCEDURES FOR ACCOUNTING, FINANCIAL
REPORTING

AND AUDITING MATTERS AND
VIOLATIONS OF THE CODE OF BUSINESS CONDUCT AND ETHICS

In order to facilitate the reporting of complaints, the Board of Directors of Pengrowth has established the following procedures for (i) the
receipt, retention and treatment of complaints regarding accounting, internal accounting controls, financial reporting or auditing matters (Accounting Matters); (ii) the receipt, retention and treatment of complaints
regarding suspected violations of the Code of Business Conduct and Ethics and any other conduct concerns (Conduct Matters); and (iii) the confidential, anonymous submission by directors, officers and employees of Pengrowth
(collectively, Members) of concerns regarding questionable Accounting Matters and Conduct Matters.

RECEIPT OF COMPLAINTS



|1. | Through Management
|-- | ------------------

Any Member may submit a
complaint regarding Accounting Matters or Conduct Matters to the management of Pengrowth without fear of dismissal or retaliation of any kind.



|2. | Through Appropriate Committee Chair
|-- | -----------------------------------

Any Member
with concerns regarding an Accounting Matter may report their concerns to the Chair of the Audit and Risk Committee. Pengrowth is committed to achieving compliance with all applicable securities laws and regulations, accounting standards, accounting
controls and audit practices. The Audit and Risk Committee of Pengrowth will oversee and be responsible for the investigation of the treatment of Member concerns relating to Accounting Matters.

Any Member with concerns regarding a Conduct Matter may report their concerns to the Chair of the Corporate Governance and Nominating Committee. The
Corporate Governance and Nominating Committee of Pengrowth will oversee treatment of Member concerns in Conduct Matters.

All such concerns
will be set forth in writing and forwarded in a sealed envelope to the General Counsel of Pengrowth or, if the submitter so desires, directly to the Chair of the Audit and Risk Committee or Corporate Governance and Nominating Committee, in care of
the General Counsel in an envelope labelled with a legend such as: To be opened by the Audit and Risk Committee only or To be opened by the Corporate Governance and Nominating Committee only.

If a Member would like to discuss any matter with the Audit and Risk Committee, the Member should indicate this in the submission and include a telephone
number at which he or she can be reached, should the Audit and Risk Committee deem such communication is appropriate. Any such envelopes received by the General Counsel that are directed to the Audit and Risk Committee will be forwarded promptly and
unopened to the Chair of the Audit and Risk Committee.



|3. | Through Anonymous Confidential Submission
|-- | -----------------------------------------

Any
Member may report concerns regarding an Accounting Matter or a Conduct Matter on a confidential or anonymous basis to Grant Thornton LLP, at 1-888-747-7171 or usecare@GrantThornton.ca.

Any Member who makes an anonymous submission must be sure to provide sufficient detail to identify the concern being raised. Given that the submission is made anonymously, the Audit and Risk Committee or
the Corporate Governance and Nominating Committee, as the case may be, will be unable to follow up if there are additional questions. The submission should, at a minimum, contain dates, places, persons involved and witnesses or other information
sufficient for recipient to investigate and determine whether the submission is valid or made in good faith such that a reasonable investigation or assessment can be conducted.

SCOPE OF ACCOUNTING MATTERS COVERED BY THESE PROCEDURES

These procedures relate to Members complaints relating to any questionable Accounting Matters, including, without limitation, the following:

TREATMENT OF COMPLAINTS

Grant Thornton LLP and Pengrowth shall inform (i) the Chair of the Audit and Risk Committee of all complaints and concerns provided to it in respect of Accounting Matters; and (ii) the Chair of
the Corporate Governance and Nominating Committee of all complaints provided to it in respect of Conduct Matters.

Upon receipt of a complaint
or concern, the Chair of the Audit and Risk Committee or Chair of the Corporate Governance and Nominating Committee, as the case may be, will (i) determine whether or not the complaint actually pertains to an Accounting Matter or a Conduct
Matter and (ii) when possible, acknowledge receipt of the complaint to the sender.

Complaints relating to an Accounting Matter will be
reviewed by the Audit and Risk Committee, outside legal counsel or such other person(s) as the Audit and Risk Committee determines to be appropriate. Complaints relating to a Conduct Matter will be reviewed by the Corporate Governance and Nominating
Committee, outside legal counsel or such other person(s) as the Corporate Governance and Nominating Committee determines to be appropriate. In any case, confidentiality will be maintained to the fullest extent possible, consistent with the need to
conduct an adequate review. If on preliminary examination the allegation is judged to be wholly without substance or merit, or not made in good faith, the allegation may be dismissed.

Prompt and appropriate investigation and corrective action will be taken when and as warranted in the judgment of the Audit and Risk Committee or the Corporate Governance and Nominating Committee, as the
case may be.

If the identity of the Member making the complaint, or assisting in investigation of the complaint, is known by anyone within
Pengrowth, the Audit and Risk Committee will monitor any disciplinary action against the Member to determine whether it could subject Pengrowth to anti-retaliation liability pursuant to Sections 806 or 1107 of the Sarbanes-Oxley Act. Pengrowth will
not discharge, demote, suspend, threaten, harass or in any manner discriminate against any individual in the terms and conditions of employment based upon any lawful actions of such individual with respect to reporting of complaints in good faith
regarding any Accounting Matter or any Conduct Matter or as otherwise specified in Section 806 of the Sarbanes-Oxley Act. In addition, Pengrowth will observe the anti-retaliation requirements of Section 1107 of the Sarbanes-Oxley Act,
which establishes penalties for retaliation against any person who provides truthful information to a law enforcement officer regarding any offense.

Pengrowth will regard the making of any deliberately false or malicious allegations by an employee as a serious offence which may result in recommendations to the Board of Directors or to senior
management of Pengrowth for disciplinary action including dismissal for cause and, if warranted, legal proceedings.

REPORTING AND RETENTION OF COMPLAINTS AND
