Re:      Pengrowth Energy Trust
         Form 40-F for year ended December 31, 2006
         Filed April 2, 2007
         File No. 001-14620

This is in response to your letter dated September 20, 2007 regarding the Form
40-F for the fiscal year ended December 31, 2006 of Pengrowth Energy Trust
("Pengrowth"). We will address each of your comments sequentially referencing
the Form 40-F filed on April 2, 2007. Pengrowth acknowledges that:

          o    it is responsible for the adequacy and accuracy of the disclosure
               in the filing;

          o    staff comments or changes to disclosure in response to staff
               comments do not foreclose the Commission from taking any action
               with respect to the filing; and

          o    it may not assert staff comments as a defense in any proceeding
               initiated by the Commission or any person under the federal
               securities laws of the United States.



1)   Disclosure Controls and Procedures
     ----------------------------------

We propose to modify the statements regarding the effectiveness of our
disclosure controls and procedures in response to the Staff's comments as
follows, with full text contained in Schedule A:

         "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 Chief Executive Officer and Chief
         Financial Officer concluded that the design and operation of our


                                                                    Page 1 of 12




         disclosure controls and procedures were effective at that reasonable
         assurance level as at December 31, 200X 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 Corporation, including the Chief Executive Officer and
         Chief Financial Officer, to allow timely decisions regarding required
         disclosure as required under Canadian and U.S. securities laws."

2)   Recording of Trust Unit Compensation and Trust Unit Award Plan
     --------------------------------------------------------------

In addressing the staff's comments, we would like to note that the Trust Unit
Award Plan (the "Plan") was designed as a short-term retention bonus in response
to competitive local labour conditions and did not form part of the long term
compensation program. As of July 1, 2007 all of the trust units awarded under
the Plan were either vested and paid out to Plan participants or forfeited.
There is currently no intention to make additional awards under the Plan and
there are no amounts recorded on Pengrowth's balance sheet related to the Plan,
subsequent to June 30, 2007.

We accounted for the awards under the Plan as follows:

         Trust units awarded under the Plan are pre-purchased in the open market
         by Pengrowth, thereafter they were transferred to and held in trust by
         an independent Trustee (Canadian Western Trust) for the sole benefit of
         Plan participants. The trust units earn monthly distributions which are
         re-invested into additional trust units. Plan participants are entitled
         to the original trust units transferred into the Plan and the
         additional trust units earned on the re-invested distributions.
         Pengrowth has treated the purchase of the trust units as deferred
         compensation, based on the cost to acquire the trust units for the
         Plan, and amortized the cost to earnings on a straight-line basis over
         the expected period of benefit that commenced on the grant date and
         ended on the vesting date. The deferred compensation cost is included
         in other assets in the consolidated financial statements. The deferred
         compensation on the balance sheet was not revalued for subsequent
         changes in the market price of the underlying trust units because the
         units were purchased on the open market and not issued from treasury.


The following are responses to the specific questions regarding the Plan posed
by the staff in its comment letter:

a) All employees employed by Pengrowth at the inception dates of the Plan
traunches were eligible to receive a Plan award. These dates were July 13, 2005,
February 28, 2006 and October 2, 2006.

b) All of the trust units awarded under the Plan traunches vested pursuant to
the vesting schedule set forth below if the eligible employee remained employed


                                                                    Page 2 of 12





on the vesting date. If the eligible employee left voluntarily or involuntarily,
all Plan awards related to that employee were immediately forfeited.

         July 13, 2005 award               1/2 vested January 1, 2006
                                           1/2 vested July 1, 2006
         Feb 28, 2006 award                all vested July 1, 2007
         Oct 2, 2006 award                 all vested July 1, 2007

c) The trust units awarded under the Plan were all settled in Pengrowth trust
units. Cash settlement of the award was not permissible. Diversification of
assets within the Plan was also prohibited (i.e. could not settle in other
equity securities).

d) The cost of acquiring the trust units awarded under the Plan was accounted
for as deferred compensation and was included in Other Assets on the
consolidated balance sheet. A detailed breakdown of Other Assets has been
provided in Note 4 of the consolidated financial statements.

e) We determined on the date of grant the number of trust units to be awarded to
an eligible employee based on a pre-determined percentage of an employee's
salary and the trust unit closing price on the date of the grant. All market
risk from the date of grant to the vesting date was borne by the eligible
employees. Any risk in the appreciation or depreciation in the market value of
these trust units were borne by the Plan participant. Distributions on the trust
units held in trust for eligible employees were re-invested in trust units and
accrued to the account of eligible employees.

f) Pengrowth's accounting policy for this Plan is to record any material gains
or losses upon the sale of unvested trust units to equity. Upon final vesting of
the July 2005 grant on July 1, 2006, a total of 19,698 trust units were unvested
with a market value of approximately $513,000. We believe the gain on the units
of approximately $144,000 is immaterial, therefore the amount was included in
earnings. The final number of unvested trust units from the February 28 and
October 2 grant has not been determined, however, we do not anticipate such
amount to be material.

g) The trust units for the Plan were purchased on the open market and held
in-trust for the eligible employees. The trust units held in the Plan were
included in the determination of basic earnings per trust unit. However, the
maximum number of trust units held in the Plan at any one time was approximately
335,000 trust units (0.19% of the weighted average number of trust units
outstanding for the year ended December 31, 2006). As a result, we believe the
effect on earnings per unit (whether such units were included or excluded) is
immaterial.

Additional Information
- ----------------------

We did not account for the trust units acquired and held in a separate trust
(the "Plan Trust") as a reduction in equity because the risks and rewards of
ownership pertaining to the trust units was transferred to the employees. Under


                                                                    Page 3 of 12




the Plan and the related trust agreement, trust units acquired by Pengrowth were
transferred to the Plan Trust which was formed for the benefit of eligible
employees. All increases and decreases in the market price of units are borne by
the Plan Trust/eligible employees. In addition, Pengrowth was not permitted to
unwind the Plan and take back the trust units except to the extent that eligible
employees ceased employment (i.e. trust units forfeited by an employee were not
reallocated to other employees within the Plan). As such, the cost of acquiring
the trust units is shown as deferred compensation which was expensed over the
vesting period (generally 12 to 18 months).

If under U.S. GAAP the trust units held under the Plan were to be considered as
a reduction in equity, we believe the reclassification of the amount in other
assets of $2.7 million at December 31, 2006 ($2.1 million at December 31, 2005)
to equity would not be material.

We reviewed paragraph 28 of APB 9 which specifically addresses and prohibits
inclusion in income of adjustments due to transactions in a company's own stock.
The only amounts included in income relating to the Plan was the amortization of
the cost of purchasing the units and the gain/loss on the disposition of trust
units that did not vest as a result of forfeitures (i.e. terminations of
employment) , which we believe to be immaterial. Trust units held in the Plan
were not revalued each reporting period.

We reviewed paragraph 12 of APB 6 which specifically addresses transactions of
treasury stock. We do not believe this is applicable as Canadian Western Trust
had legal title over the trust units purchased for the Plan which were held by
the Plan Trust. All economic risks and rewards of ownership were transferred to
the eligible employees through the Plan Trust.

Your comment letter refers to EITF 94-17, which we confirmed with Mr. Ryan Milne
should have read EITF 94-7 and its successors. We reviewed EITF 00-00-19, the
successor to EITF 94-7, which specifically addresses transactions of derivative
financial instruments indexed to and potentially settled in a company's own
stock. We do not think this is applicable as continuous employment with
Pengrowth from the grant date to the vesting date were the only conditions for
eligibility. Paragraph 3 of EITF 00-19 specifically states that this EITF does
not apply to contracts issued to compensate employees.

3.   Reconciliation of Financial Statements to United States Generally Accepted
     Accounting Principles
     --------------------------------------------------------------------------

We have previously considered the application of Accounting Series Release 268
("ASR 268") and Emerging Issues Task Force Topic D-98 ("EITF D-98") during the
course of the preparation of our financial statements. As you have requested, we
have again reviewed ASR 268 and EITF D-98 and considered their application to
our financial statements. For the reasons set forth below, we continue to be of
the view that ASR 268 and EITF D-98 do not require the presentation of our Trust
Units as temporary equity or as a mezzanine level outside of permanent equity.


                                                                    Page 4 of 12





Summary of Regulatory Provisions
- --------------------------------

ASR 268 adopted Rule 5-02.28 of Regulation S-X which requires preferred
securities that are redeemable for cash or other assets to be classified outside
of permanent equity if they are redeemable (1) at a fixed or determinable price
on a fixed or determinable date, (2) at the option of the holder, or (3) upon
the occurrence of an event that is not solely within the control of the issuer.
Although the rule specifically describes and discusses preferred securities,
EITF D-98 states that it is the belief of SEC staff that Rule 5-02.28 of
Regulation S-X also provides analogous guidance for other equity instruments
including, for example, common stock and derivative instruments that are
classified as equity pursuant to Issue No. 00-19, "Accounting for Derivative
Financial Instruments Indexed to, and Potentially Settled in, a Company's Own
Stock."

EITF D-98 also states that ASR 268 and the interpretive guidance in EITF D-98
continue to be applicable for instruments that are not within the scope of FASB
Statement No. 150, Accounting for Certain Financial Instruments with
Characteristics of both Liabilities and Equity. FASB 150 requires an issuer to
classify the following instruments as liabilities:

1.   a financial instrument issued in the form of shares that is mandatorily
     redeemable - that embodies an unconditional obligation requiring the issuer
     to redeem it by transferring its assets as a specified or determinable date
     (or dates) or upon an event that is certain to occur;

2.   a financial instrument, other than an outstanding share, that, at
     inception, embodies an obligation to repurchase the issuer's equity shares,
     or is indexed to such an obligation, and that requires or may require the
     issuer to settle the obligation by transferring assets (for example, a
     forward purchase contract or written put option on the issuer's equity
     shares that is to be physically settled or net cash settled);

3.   a financial instrument that embodies an unconditional obligation, or a
     financial instrument other than an outstanding share that embodies a
     conditional obligation, that the issuer must or may settle by issuing a
     variable number of its equity shares, if, at inception, the monetary value
     of the obligation is based solely or predominantly on any of the following:

     (a)  a fixed monetary amount known at inception, for example, a payable
          sellable with a variable number of the issuer's equity shares;

     (b)  variations in something other than the fair value of the issuer's
          equity shares, for example, a financial instrument indexed to the S&P
          500 and settleable with a variable number of the issuer's equity
          shares;

     (c)  variations inversely related to changes in the fair value of the
          issuer's equity shares, for example, a written put option that could
          be net shares settled.


                                                                    Page 5 of 12





Based on our analysis, the Trust Units do not fall within the scope of FASB 150,
thus we have considered the applicability of ASR 268 and EITF D-98.

Application of ASR 268 and EITF D-98 to Canadian Business Trusts
- ----------------------------------------------------------------

Unlike companies which are formed by incorporation pursuant to the companies'
statute in their governing jurisdiction, Canadian business trusts are not formed
pursuant to any governing statute and are instead created by contract. As a
result, the legal structure of Canadian business trusts varies significantly
from trust to trust. Due to the uniqeness of each trust document, the accounting
for Canadian trust units under US GAAP must be determined for each trust and
cannot be generalized on an industry basis. The analysis must be performed on
each trust in accordance with the trust deed contract pursuant to which it was
formed.

In addition, there is a significant difference between Canadian INCOME trusts
where the only assets held by the trust are debt securities of the underlying
operating company, and a Canadian ROYALTY trust, such as Pengrowth, where the
majority of the assets held by the trust are comprised of a royalty or net
profits interest, and not debt.

These elements of the redemption feature applicable to Pengrowth's Trust Units
are significantly different than the redemption feature of the vast majority of
Canadian income trusts. Most Canadian income trusts provide a redemption feature
whereby the holders of trust units may at any time redeem all of their trust
units for debt obligations of the underlying operating entity which holds the
business of the trust. In the event of the redemption of all of the outstanding
trust units, the financial position of the entity would be dramatically altered
in that the redemption would cause the issuance of a significant amount of debt
by the operating entity, which that operating entity would then have to service.
Pengrowth's structure is much different.

Details of the Pengrowth Structure
- ----------------------------------

Pengrowth Energy Trust (the "Trust") was created on December 2, 1988 pursuant to
a Trust Indenture between Pengrowth Corporation (the "Corporation") and
Computershare Trust Company of Canada.

The assets held in the Trust at December 31, 2006 consist of 99.9% of the
outstanding Royalty Units of the Corporation, 90.9% of the outstanding common
shares of the Corporation, intercompany debt, 100% of the common shares of
Esprit Exploration Ltd. ("Esprit"), a net profits interest in the Canadian
resource properties of Esprit, and an interest in certain oil and gas processing
facilities in the Judy Creek / Swan Hills area of Alberta.

Terms of the Redemption Right
- -----------------------------

Article 12 of the Trust Indenture provides that the Trust Units are redeemable
at any time on demand by a unitholder upon delivery to the Trust of the
certificates representing the Trust Units accompanied by duly completed and
properly executed notice requesting redemption. The redemption price for each
Trust Unit is defined to be THE LESSER OF: (1) 95% of the simple average closing


                                                                    Page 6 of 12




price of the Trust Units for each of the 10 trading days after the units are
surrendered for redemption; and (2) the closing price on the date that the Trust
Units are surrendered for redemption. However, the entitlement of unitholders to
receive cash upon the redemption of their Trust Units is subject to the
limitations that: (1) the total amount payable by the Trust in respect of all
units tendered for redemption in the same calendar month cannot exceed $25,000
(which limitation may only be waived by the Board of Directors of the
Corporation); (2) at the time the Trust Units are tendered for redemption the
Trust Units must be listed for trading on a stock exchange which the directors
of the Corporation consider, in their sole discretion, to provide representative
fair value prices for the Trust Units; and (3) the normal trading of the Trust
Units must not be suspended or halted on a stock exchange on which the Trust
Units are listed within more than 5 trading days during the 10 trading day
period commencing immediately after the date on which the Trust Units are
surrendered for redemption.

If a unitholder is not entitled to receive the cash redemption price as a result
of the limitation set forth above, then the redemption price for the Trust Units
surrendered for redemption is the fair market value thereof as determined by the
directors of the Corporation which is to be paid and satisfied by way of a
distribution in specie of a pro rata share of the Royalty Units and other assets
(excluding facilities, pipelines or other assets associated with oil and gas
production) held by the Trust at such time.

In summary, while unitholders have the right to require the Trust to redeem all
of their Trust Units at any time, this redemption right is subject to the
significant caveat that the total amount of cash payable by the Trust in any one
month is not to exceed $25,000. Putting this $25,000 limitation in context,
based upon the closing price of Pengrowth units on Friday, September 28, 2007 of
$18.64, Pengrowth has a market capitalization of $4,581,092,071. If all
unitholders requested the redemption of their Trust Units, as the redemption
price is set at 95% of the trading price, this results in an aggregate
redemption price of $4,352,037,467, which would take 174,081 months (14,507
years) to pay out at $25,000 per month. In addition, the $25,000 limit
represents only 0.02% of Pengrowth's monthly net revenue of $119,333,500.

Given the restrictive nature of the $25,000 limit, when considering the impact
of the redemption of all or a significant portion of the Trust Units, the
requirements of the Trust Indenture that provide that where unitholders have
requested the redemption of Trust Units above the $25,000 threshold the
redemption price is to be paid and satisfied by the distribution in specie of a
pro rata share of Royalty Units and other assets (excluding facilities,
pipelines or other assets associated with oil and gas production) held by the
Trust are the most pertinent. To understand the effect of this provision, it is
necessary to review the terms of the Royalty Units.

Terms of the Royalty Units
- --------------------------

The Royalty Units were issued pursuant to the terms of a Royalty Indenture
between Pengrowth Corporation and Computershare Trust Company of Canada
originally dated December 2, 1988 and which has been successively amended, with
the latest amendments being made as of June 11, 2007. Under the Royalty


                                                                    Page 7 of 12




Indenture, royalty unitholders are entitled to a royalty calculated as 99% of
royalty income, which is essentially the net income derived by the Canadian
resource properties of the Corporation. In the event of the liquidation of the
Corporation, the Royalty Indenture provides that the assets of the Corporation
are to be liquidated and the proceeds are to be used to repay the outstanding
indebtedness of the Corporation; any remaining proceeds are to be distributed as
a special distribution to the royalty unitholders. In the event of a
liquidation, dissolution or winding-up of the Corporation, the holders of the
outstanding shares of the Corporation are only entitled to participate in
respect of the assets of the Corporation other than its Canadian resource
properties and the proceeds therefrom.

Under the Royalty Indenture, the Corporation and Computershare have the ability
to make minor amendments to the Royalty Indenture provided that the holders of
royalty units are not prejudiced as a result. Any significant amendment to the
royalty or the rights of royalty unitholders must be approved by the royalty
unitholders by an extraordinary resolution passed at a meeting of royalty
unitholders.

As summarized above, the Royalty Units include the right to participate in
profits, the right to share in assets on liquidation and the right to vote,
which we submit are the essential elements of an equity security and that
therefore the Royalty Units should be considered to be equity securities of
Pengrowth.

Royalty Units are not publicly traded and must therefore be converted into Trust
Units to be readily bought or sold.

Purpose of the Redemption Feature
- ---------------------------------

From the foregoing, it is apparent that the redemption feature does not provide
trust unitholders with an effective economic right, in that pursuant to the
redemption they will either receive a cash amount, if the $25,000 limit is not
exceeded in that month, that is equal to 95% of the LESSER of the closing price
on that day or the 10 day average closing price thereafter, which, in virtually
all cases, will result in the holder receiving a lesser price than they would
have received if they had sold on the market. Otherwise, if the $25,000 limit is
exceeded, they will receive securities of Pengrowth and Esprit which are private
companies and will lose the benefits they currently enjoy of holding securities
of a public entity, including the liquidity provided by the stock exchange
listings of the Trust Units.

In addition, prior to redemption, a holder of Trust Units would have a
beneficial interest in all of the property of the Trust, including the Royalty
Units issued by the Corporation, the net profits interest of Esprit, the
indebtedness of the Corporation and Esprit to the Trust and the Judy Creek /
Swan Hills facilities. However, in respect of redemptions above the $25,000 per
month limit, holders of Trust Units are entitled to receive a distribution in
specie of a pro rata share of only the Royalty Units and other assets (excluding
facilities, pipelines or other assets associated with oil and gas production) of
the Trust. As the "facilities, pipelines or other assets associated with oil and
natural gas production" are excluded, upon a redemption a former holder of Trust
Units will receive less property than they beneficially had an interest in prior
to the redemption.


                                                                    Page 8 of 12





These shortcomings in the redemption feature are a reflection of the fact that
the purpose of the redemption feature is not to provide the holder with a
liquidation opportunity, but instead to satisfy a requirement of Canadian law
that is a necessary for the Trust to maintain its tax status.

Therefore, we do not believe that the redemption right gives the investor a
substantive right to obtain assets of Pengrowth.

Conclusions
- -----------

The redemption feature of Pengrowth's Trust Units is subject to three
significant limitations:

1.   The total amount payable by the Trust in any one calendar month is not to
     exceed $25,000;

2.   In respect of redemptions above the $25,000 per month limit, unitholders
     receive less property than they had a beneficial interest in prior to the
     redemption as the interest of the Trust in the Judy Creek / Swan Hills
     facilities are excluded from the redemption.

3.   In respect of redemptions above the $25,000 per month limit, the former
     holders of trust units will receive Royalty Units of the Corporation which
     are merely another form of equity securities.

In the event of the redemption of all outstanding Trust Units of Pengrowth, the
former holders of Trust Units would essentially step into the shoes of the Trust
and would become the direct holders of the Royalty Units, net profit interests
and indebtedness which is currently issued by the Corporation and Esprit. The
former trust unitholders would still hold equity securities, the Royalty Units,
but they would do so directly rather than indirectly through the Trust.
Likewise, the former trust unitholders would directly hold the indebtedness of
the Corporation and Esprit which is currently held by the Trust. No additional
indebtedness of the Corporation or Esprit would be created by the redemption.

In ASR 268, the Commission described the underlying rationale for these rules as
follows:

         There is a significant difference between a security with mandatory
         redemption requirements or whose redemption is outside the control of
         the issuer and conventional equity capital. The Commission believes
         that it is necessary to highlight THE FUTURE CASH OBLIGATIONS attached
         to this type of security so as to distinguish it from permanent
         capital. It is expected that the rules would provide more meaningful
         presentation of the financial obligations of those companies which
         finance operations through the use of such securities. [Our emphasis]

In ASR 268, the Commission also described the intent of the disclosure provided
by these rules as follows:


                                                                    Page 9 of 12





         The rules are intended to highlight THE FUTURE CASH OBLIGATIONS
         attached to redeemable preferred stock through appropriate balance
         sheet presentation and footnote disclosure. [Our emphasis.]

As set forth above, the future cash obligations associated with the redemption
feature of Pengrowth's Trust Units are capped at $25,000 per month, which
represents 0.02% of Pengrowth's monthly net revenue of $119,333,500 (based on
the six months ended June 30, 2007) and we believe such amount is de minimis and
non-substantive. Accordingly, the rationale for the disclosure contemplated by
ASR 268 and EITF D-98 does not apply in this case.

We also submit that to provide the alternative disclosure contemplated by Rule
5-02.28 of Regulation S-X, ASR 268 and the EITF D-98 would be misleading in that
it would suggest that the redemption feature of Pengrowth's Trust Units creates
a risk that Pengrowth could become subject to significant additional
indebtedness, when in fact the operation of the redemption feature could not
cause such a result.

In light of the foregoing analysis, we have reconsidered the disclosure in Note
23(e) of our Audited Consolidated Financial Statements for the year ended
December 31, 2006. In light of the foregoing analysis, we are of the view that
that disclosure provided could be enhanced such that it is more easily
understood by users of the financial statements. Accordingly, we propose that in
future filings, note 23(e) be replaced with the following:

         Under U.S. GAAP, securities which are subject to mandatory redemption
         requirements or whose redemption is outside the control of the issuer
         must be classified outside of permanent equity and are to be recorded
         at their redemption amount at each balance sheet date with changes in
         redemption amount being charged to deficit. The amount charged to
         deficit representing the change in redemption amount between balance
         sheet dates for the periods presented must also be disclosed.
         Furthermore, the balance sheet disclosure of "trust unitholders'
         capital" would not be permitted and trust unitholders' capital would be
         reclassified to mezzanine equity, a liability.

         The trust units are redeemable at the option of the holder at a
         redemption price equal to the lesser of 95% of the average closing
         price of the trust units for the 10 trading days after the trust units
         have been surrendered for redemption and the closing price on the date
         the trust units have been surrendered for redemption. However, the
         total amount payable by the Trust in cash in any one calendar month is
         limited to a maximum of $25,000. Redemptions in excess of the cash
         limit must be satisfied by way of a distribution in specie of a pro
         rata share of royalty units and other assets, excluding facilities,
         pipelines or other assets associated with oil and gas production, which
         are held by the Trust at the time the trust units are to be redeemed.
         As a result of the significant limitation on the cash amount payable by
         the Trust in respect of redemptions, and that any royalty units issued
         would have similar characteristics of the trust units and be
         convertible back into trust units, the trust units have not been
         classified as redeemable equity for the purposes of U.S. GAAP.


4.   All of Pengrowth's stock based compensation plans call for settlement in
     trust units with no provisions for any cash settlement (see discussion with
     respect to comment 3 on equity classification of Pengrowth trust units).
     Pengrowth classifies its trust units as equity therefore unit based
     compensation arrangements that are settleable only in trust units are also
     classified as equity.

Paragraph 32 of FASB 123(R) states that options or similar awards "shall be
classified as liabilities if (a) the underlying shares are classified as
liabilities or (b) the entity can be required under any circumstances to settle
the option or similar instrument in cash or other assets." There are no
circumstances that would require or allow Pengrowth to repurchase the vested
units or settle these awards in cash or other assets.

As there is no repurchase feature incorporated into any of Pengrowth's unit
based compensation plans and all of the risks and rewards of ownership are borne
by the eligible employees, they do not meet the conditions in paragraph 31 of
FAS 123(R). Paragraph 31 of FAS 123(R) specifically states that shares that do
not meet these conditions shall be classified as equity.

As previously mentioned, there are no repurchase features in any of Pengrowth's
unit based compensation plans and the underlying trust units are equity
classified. Thus, Pengrowth's unit based compensation plans to not meet the
requirements of SAB 14:E.

Schedule A

DISCLOSURE CONTROLS AND PROCEDURES

As a Canadian  reporting  issuer with securities  listed on both the TSX and the
NYSE,  Pengrowth  is required to comply with  Canadian  Multilateral  Instrument
52-109 - Certification of Disclosure in Issuers' Annual and Interim Filings ("MI
52-109"),  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 and the Chief  Financial  Officer  must
assess and  certify  as to the  effectiveness  of our  disclosure  controls  and
procedures  as defined in Canada by MI 52-109 and in the United  States by Rules
13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the "Exchange
Act"), as amended.

The Chief Executive Officer,  James S. Kinnear, and the Chief Financial Officer,
Christopher A. Webster,  evaluated the effectiveness of Pengrowth's  "disclosure
controls  and  procedures"  as such  term is  defined  in MI  52-109  and  Rules
13a-15(e) and  15d-15(e) of the Exchange Act for the period ending  December 31,
200X.  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 Chief  Executive  Officer  and  Chief  Financial
Officer  concluded that the design and operation of our disclosure  controls and
procedures were effective at that reasonable  assurance level as at December 31,
200X 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  Corporation,  including the Chief Executive Officer and
Chief Financial Officer, to allow timely decisions regarding required disclosure
as required under Canadian and U.S. securities laws.

It should be noted that while  Pengrowth's  Chief  Executive  Officer  and Chief
Financial  Officer 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.
