                    INFORMATION REQUIRED IN THE PROSPECTUS





                                       1



                            PENGROWTH ENERGY TRUST

                             5,000,000 Trust Units

            DISTRIBUTION REINVESTMENT AND TRUST UNIT PURCHASE PLAN

On July 1, 1992,  Pengrowth  Energy Trust  (hereinafter  referred to as "we" or
"us" or the "Trust")  established a  Distribution  Reinvestment  and Trust Unit
Purchase Plan (the "Plan").  The purpose of the Plan is to provide holders (the
"Unitholders")  of the trust units of the Trust ("Trust Units") with a means to
reinvest  distributions  declared  and  payable  to  them as  Unitholders  into
additional Trust Units.

The  Plan  was  first  amended  on  January  15,  2003  to  encourage   greater
participation by providing that reinvested  distributions would be converted to
Trust Units at a 5%  Discount  to the  prevailing  market  price.  The Plan was
revised on July 27,  2004 to reflect  the  reclassification  of the Trust Units
existing  at that time into class A trust  units  ("Class A Units") and class B
trust units ("Class B Units"). On July 27, 2006 the Plan was further amended to
reflect the consolidation of the Trust's  outstanding Class A Units and Class B
Units into Trust  Units.  Finally,  on June 13 we further  amended  the Plan to
provide,  among other things,  for the  participation in the Plan by registered
holders of Trust Units resident in the United  States.  Class A Units that were
not  consolidated  into Trust Units on July 27, 2006 comprise less than 0.1% of
the  presently  outstanding  Trust  Units.  Holders  of  Class A Units  are not
eligible to participate in the Plan.

A participant in the Plan may obtain  additional Trust Units by reinvesting all
of the cash  distributions  paid on the Trust Units held by the participant net
of  withholding  taxes,  if any,  without  paying any brokerage  commissions or
service charges.  Our  distributions are paid on the 15th day of each February,
May,  August and  November  in each year,  or, if so  directed  by the board of
directors of Pengrowth Corporation (the "Corporation"), on the 15th day of each
calendar month (the "Distribution Date").

A participant  may also make optional cash payments,  which will be invested in
Trust  Units on the same basis as provided  for in the Plan for  distributions.
Participants  may  invest a maximum  of Cdn.  $1,000  per month  (the  "Maximum
Contribution  Amount")  or, for U.S.  Participants,  U.S.$900 per month or such
other amount as may be determined by the board of directors of the  Corporation
(the "Maximum U.S. Contribution Amount") through such optional cash payments.

The purchase price of Trust Units purchased from treasury:  (i) with reinvested
distributions of Trust Units; or (ii) from investing optional cash payments, is
calculated  based on the 20 day weighted  average  trading  price for the Trust
Units traded on the Toronto Stock Exchange  ("TSX") during the period ending on
the day immediately  preceding the Distribution  Date, less 5%. Our Trust Units
are listed and trade on the TSX under the symbol "PGF.UN" and on the NYSE under
the symbol "PGH". The simple average of the high and low trading prices for the
Trust  Units  on the TSX for the five  days  preceding  June 13,  2007 was Cdn.
$19.94.  The  closing  prices for our Trust Units on the TSX and on the NYSE on
June 13, 2007 were Cdn. $19.87 and U.S. $18.72, respectively.

The  distributions  paid by us are  dependent  on cash  flow and are  therefore
subject to fluctuations in the quantity of petroleum and natural gas substances
produced,  prices received for that production,  hedging contract  receipts and
payments, currency exchange rates, taxes, our direct expenses, reclamation fund


                                       2


contributions,   operating   costs,   debt  service  charges  and  general  and
administrative   expenses.   See  "Special   Note   Regarding   Forward-Looking
Statements" in this  prospectus.  See also the section titled "Risk Factors" in
our annual  report on Form 40-F for the fiscal  year ended  December  31,  2006
filed April 2, 2007.

We cannot anticipate  proceeds from the issuance of Trust Units pursuant to the
Plan, which will depend upon the market price of our Trust Units, the extent of
Unitholder  participation  in the  Plan  and  other  factors.  We will  not pay
underwriting  commissions  in connection  with the Plan but will incur costs of
approximately  U.S. $239,953 in  connection  with  this  offering  and  will be
responsible for the ongoing  administrative costs associated with the operation
of the Plan.

Neither the United States  Securities and Exchange  Commission  (the "SEC") nor
any state  securities  commission  has approved or  disapproved  of these Trust
Units  or  determined  if  this   prospectus  is  truthful  or  complete.   Any
representation to the contrary is a criminal offense.

The date of this prospectus is June 15, 2007.

                  ENFORCEABILITY OF CERTAIN CIVIL LIABILITIES

The Trust is a trust formed under, and governed by, the laws of the Province of
Alberta,  Canada. Most of the directors and officers of the Corporation,  which
is the  administrator  of the  Trust,  and  most of the  experts  named in this
prospectus,  are  residents  of Canada or otherwise  reside  outside the United
States,  and all or a substantial  portion of their assets and our assets,  are
located  outside the United  States.  We have appointed an agent for service of
process in the United  States,  but it may be  difficult  for  Unitholders  who
reside in the United  States to effect  service  within the United  States upon
those  directors,  officers  and  experts who are not  residents  of the United
States.  It may also be  difficult  for  Unitholders  who  reside in the United
States to realize in the United  States upon  judgments of courts of the United
States  predicated  upon our civil  liability  and the civil  liability  of the
directors and officers of the  Corporation  and experts under the United States
federal securities laws. We have been advised by our Canadian counsel,  Bennett
Jones LLP,  that a judgment of a United  States  court  predicated  solely upon
civil liability  under United States federal  securities laws would probably be
enforceable  in Canada if the United  States  court in which the  judgment  was
obtained has a basis for jurisdiction in the matter that would be recognized by
a Canadian  court for the same  purposes.  We have also been advised by Bennett
Jones LLP, however,  that there is substantial doubt whether an action could be
brought in Canada in the first  instance on the basis of  liability  predicated
solely upon United States federal securities laws.

We have appointed CT Corporation System, located at 111- 8th Ave, New York, New
York-  10011,  as our agent for  service of  process  in the  United  States in
connection with any investigation or administrative proceeding conducted by the
SEC, and any civil suit or action  brought  against or involving us in a United
States court arising out of or related to or  concerning  the offering of Trust
Units under this prospectus.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This  prospectus  contains  forward-looking  statements  within the  meaning of
securities laws,  including the "safe harbor" 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 prospectus include,
but are not limited to,  statements  with respect to:  benefits  and  synergies
resulting from the Corporation's  corporate and asset acquisitions during 2006,
business  strategy  and  strengths,  goals,  focus  and  the  effects  thereof,
acquisition  criteria,  capital expenditures,  reserves,  reserve life indices,
estimated   production,   production  additions  from  the  Corporation's  2007
development  program,  the  impact  on  production  of  divestitures  in  2007,
remaining producing reserves lives,  operating expenses,  net present values of


                                       6


future net revenue from reserves,  commodity prices and costs,  exchange rates,
the impact of contracts for commodities,  development  plans and programs,  tax
horizons,  future income  taxes,  taxability  of  distributions,  the impact of
proposed   changes  to  Canadian  tax  legislation  or  U.S.  tax  legislation,
abandonment  and  reclamation  costs,  government  royalty  rates and  expiring
acreage.  Statements  relating to "reserves"  are deemed to be  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 the  Corporation's
current  beliefs  as well as  assumptions  made by, and  information  currently
available to, the Corporation  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
distributions  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  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, objectives, expectations and anticipations,
estimates and intentions  expressed in such forward-looking  statements.  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;  the  Corporation's  ability  to  replace  and expand oil and gas
reserves; 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;   compliance  with  environmental  laws  and
regulations;  changes in tax laws;  the  failure  to  qualify as a mutual  fund
trust;  and the  Corporation's  ability to access external  sources of debt and
equity  capital.  Further  information  regarding these factors may be found in
financial  statements as at and for the financial  year ended December 31, 2007
and the related  management's  discussion  and  analysis  in the  Corporation's
annual  information  form for the year ended  December 31, 2007 and in our most
recent management  information  circular,  quarterly  reports,  material change
reports and news releases.  Copies of the Corporation's Canadian public filings
are available on SEDAR at www.sedar.com. The Corporation's U.S. public filings,
including  the  Corporation's  most  recent  annual  report  on  Form  40-F  as
supplemented  by its filings of Form 6-K, are available at www.sec.com  and are
incorporated by reference in this prospectus.

We caution 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 the Corporation  and the Trust,  investors and others
should carefully  consider the foregoing  factors and other  uncertainties  and


                                       7


potential events. Furthermore, the forward-looking statements contained in this
prospectus  are  made  as of the  date  of  this  prospectus  and  neither  the
Corporation nor the Trust  undertakes any obligation to up-date  publicly or to
revise any of the included forward-looking  statements,  whether as a result of
new information,  future events or otherwise,  except as required by applicable
law. The forward-looking  statements contained in this prospectus are expressly
qualified by this cautionary statement.

                                  RISK FACTORS

Before you decide to participate in the Plan and invest in our Trust Units, you
should be aware of certain material risks in making such an investment.  Before
you decide to  participate  in the Plan and purchase  Trust  Units,  you should

                                   THE TRUST

INTRODUCTION

The Trust is an oil and gas royalty  trust that was  created  under the laws of
the Province of Alberta,  Canada on December 2, 1988.  The purpose of the Trust
is to purchase and hold royalty units  ("Royalty  Units") and other  securities
issued by the  Corporation,  its majority  owned  subsidiary,  as well as other
investments and to issue Trust Units to members of the public.  The Corporation
directly  and  indirectly  acquires,  owns and manages  working  interests  and
royalty  interests  in oil  and  natural  gas  properties.  The  Trust  and the
Corporation are managed by Pengrowth Management Limited (the "Manager").

THE TRUST

The Trust is governed by the Trust's amended and restated trust indenture dated
June 11, 2007 between the Corporation  and  Computershare,  as the trustee (the
"Trust Indenture"). Under the Trust Indenture, the Trust has issued Trust Units
to  Unitholders  who  are the  beneficiaries  of the  Trust.  Each  Trust  Unit
represents  a  fractional  undivided  beneficial  interest  in the  Trust.  Our
Unitholders  are entitled to receive  monthly  distributions  in respect of the
royalty ("Royalty") the Corporation pays to the holders of the Royalty Units it
has issued, and in respect of investments that are held directly by us.

The Trust presently holds 90.9% of the outstanding common shares in the capital
of the  Corporation  ("Common  Shares")  and  100%  of the  Royalty  Units.  In
addition,  the Trust holds other permitted  investments,  including oil and gas
processing  facilities and cash. The Trust's share of Royalty income,  together
with any lease,  interest  and other  income of the  Trust,  less  general  and
administrative  expenses,  management  fees,  debt  repayment,  taxes and other
expenses  (provided that there is no duplication of expenses  already  deducted
from Royalty income), forms the distributable cash of the Trust.

THE CORPORATION

The Corporation  was created under the laws of the Province of Alberta,  Canada
on December 30, 1987. The name of the  Corporation  was changed from "Pengrowth
Gas Corporation" to "Pengrowth  Corporation" in 1998. The Corporation has 1,100
Common  Shares  outstanding,  1,000 of which  are owned by the Trust and 100 of
which are owned by the Manager.

The  Corporation  acquires,  owns and operates  working  interests  and royalty
interests in oil and natural gas  properties  directly and  indirectly  through
subsidiary  corporations and  partnerships.  The Corporation has issued Royalty
Units which  entitle the holders  thereof to receive a 99% share of the Royalty
income related to the oil and natural gas interests of the Corporation.

The authorized capital of the Corporation  includes  exchangeable  shares which
will have  economic and voting  rights  substantially  equivalent  to the Trust
Units and which will be exchangeable,  on certain conditions,  for Trust Units.
Holders of exchangeable shares will not receive dividends or distributions from
the  Trust,  but  will  receive  additional  exchangeable  shares  in  lieu  of
distributions. These additional exchangeable shares would be distributed by way
of a stock split. To facilitate  voting rights for the  exchangeable  shares, a


                                       9


special voting unit of the Trust has been authorized  which will be entitled at
any  meeting  of  Unitholders  to a number  of votes  equal  to the  number  of
outstanding  exchangeable shares (not including exchangeable shares held by the
Trust or its  subsidiaries).  There are  presently  no  issued  or  outstanding
exchangeable shares.

THE TRUST'S SUBSIDIARIES

In  addition  to its  interest  in the  Corporation,  the Trust owns all of the
issued and  outstanding  shares of Esprit  Exploration  Ltd. The Trust receives
interest  on the  principal  amount of  Esprit  Exploration  Ltd.'s  unsecured,
subordinated promissory notes and payments from the net profit interest granted
to the Trust by Esprit  Exploration Ltd. The  Corporation,  Esprit Energy Trust
and Esprit  Exploration  Ltd. and all its  subsidiaries  entered into an agency
agreement dated October 2, 2006 whereby the  Corporation  would provide certain
services to Esprit  Energy  Trust and Esprit  Exploration  Ltd.  and all of its
subsidiaries. Services generally include, but are not limited to, the provision
of all operating,  financial,  strategic,  legal,  regulatory,  human resource,
technology,  record keeping,  record management and general and  administrative
services. Esprit Exploration Ltd. was acquired in connection with the strategic
business  combination  with  Esprit  Energy  Trust on October  2, 2006.  Esprit
Exploration Ltd. holds 100% of the issued and outstanding shares of Canadian 88
Energy Resources  Corporation.  Each of Esprit Exploration Ltd. and Canadian 88
Energy  Resources  Corporation  are created  under the laws of the  Province of
Alberta, Canada.

President,  Chief Executive  Officer and a director of the  Corporation,  owns,
directly or indirectly,  all of the issued and outstanding voting securities of

TRUST UNIT CONSOLIDATION

On July 27, 2006, the Trust completed the consolidation  (the  "Consolidation")
of its then outstanding Class A Units,  Class B Units and trust units remaining
in the form in existence prior to the  reclassification  which occurred on July
27,  2004  ("Prior  Trust  Units")  into a single  class of  Trust  Units.  The
Consolidation  was effected  through  amendments  to the Trust  Indenture.  The
principal  amendments to the Trust Indenture were as follows: (a) the residency
restrictions  attached to the Class B Units were removed; (b) the Class B Units
were renamed as Trust Units;  (c) the Prior Trust Units were converted to Trust
Units; and (d) the Class A Units were converted to Trust Units,  other than the
Class A Units for which an election and  declaration of Canadian  residency was
provided  by the  holder  thereof.  Class A Units  for  which an  election  and
declaration of Canadian residency was provided remain outstanding but the terms
thereof have been amended to prohibit the transfer of such Class A Units.  Such
outstanding Class A Units may be converted to Trust Units or redeemed for cash,
subject to the terms of the Trust Indenture,  at any time and at the discretion
of the holder thereof.  As a result,  the Class A Units were de-listed from the
TSX, the renamed  Class B Units  remained  listed and posted for trading on the
TSX as Trust  Units  with a new  symbol  "PGF.UN",  and the  Trust  Units  were
substitutionally  listed  in place of the  Class A Units on the NYSE  under the
symbol "PGH".

CAPITALIZATION AND INDEBTEDNESS

The  Trust  Units  are  listed  on  the  TSX  and  the  NYSE,  and  our  market
capitalization as of May 31, 2007 was approximately Cdn. $4,885,770,000.

Our  total   indebtedness   as  of  May  31,   2007  was   approximately   Cdn.
$1,507,561,000.


                                      11


                                USE OF PROCEEDS

We have no basis for estimating precisely either the number of Trust Units that
may be sold  under the Plan or the  prices  at which  such  Trust  Units may be
issued or acquired.  The amount of the proceeds that we may receive will depend
on the  number  of  participants  in  the  Plan,  the  amount  of  the  monthly
distributions that we pay and the amount invested by participants in additional
Trust Units through the optional cash purchase  component of the Plan (see "The
Plan"  below).  We do not expect the amount of  proceeds  that we receive to be
material. The net proceeds from the sale of the Trust Units will be principally
used for general corporate purposes.

                                    THE PLAN

PURPOSE OF THE PLAN

The purpose of the Plan is to provide Unitholders with a means to: (i) reinvest
distributions  declared and payable to them as Unitholders,  net of withholding
taxes,  if any,  into  additional  Trust  Units  without  paying any  brokerage
commissions  or service  charges and at a 5%  Discount  to the  average  market
price;  and (ii) invest optional cash payments by purchasing  additional  Trust
Units  without  paying any  brokerage  commissions  or service  charges at a 5%
Discount to the average market price.

Distributions  are paid to the Unitholders of record ten business days prior to
the  Distribution  Date or such other  dates as the board of  directors  of the
Corporation may determine (the "Record Date").

We seek to  provide a  sustainable  and  predictable  stream of  distributions;
however  the  distributions  paid  by us are  dependent  on cash  flow  and are
therefore  subject to fluctuations in the quantity of petroleum and natural gas
substances  produced,  prices received for that  production,  hedging  contract
receipts and payments,  currency exchange rates,  royalties,  taxes, our direct
expenses, reclamation fund contributions, operating costs, debt service charges
and  general  and  administrative  expenses.  Distributions  are set at  levels
commensurate with cash flow expectations and internal cash requirements.

PARTICIPATION IN THE PLAN

You  are  eligible  to  participate  in the  Plan if you  are a  registered  or
beneficial holder of at least one Trust Unit,  resident in Canada or the United
States and meet the requirements outlined below.

Registered  Unitholders  are  eligible to enroll in the Plan,  and may do so by
completing a participation  form and sending it to Computershare  Trust Company
of Canada  (the  "Plan  Agent")  at the  address  set out in  "Notices"  below.
Beneficial  Unitholders whose Trust Units are not registered in their own names
may  participate  in  this  Plan  by  either:  (a)  having  their  Trust  Units
transferred  into their own names;  or (b) by instructing  their broker,  trust
company, bank or other nominee to participate in the Plan on their behalf while
maintaining the Trust Units in their nominee's account. It is not necessary for
Beneficial  Unitholders  to remove their Trust Units from their  account with a


                                      12


broker or other nominee to enroll in this Plan. You may obtain a  participation
form at any time by either  providing a written request to the Plan Agent or by
visiting our web site at www.pengrowth.com. If you are a registered Unitholder,
once you  have  enrolled  in the  Plan,  you will  remain  enrolled  until  you
discontinue  participation  or until we terminate  the Plan.  See  "Amendments,
Suspension or Termination  of Plan and Plan Agent" below.  Please note that not
all  nominees  will  allow,  nor  is  any  nominee  required  to  allow,   your
participation in the Plan. If you wish to participate and your nominee does not
allow it, it is your  responsibility  to either  transfer your Trust Units to a
different  nominee  allowing  participation  or into  your own name and  enroll
directly.

Only  residents  of Canada  and the  United  States  are  currently  allowed to
participate in the Plan.  Unitholders  resident in other jurisdictions shall be
allowed to participate  in the Plan only after we determine that  participation
should be made available to those Unitholders taking into account the necessary
steps to comply with the laws  relating to the  offering  and the sale of Trust
Units in the jurisdictions of residence of those Unitholders.

If the  Trust  Units are  registered  in more  than one  name,  all  registered
Unitholders must sign the participation form. In addition, if your holdings are
registered in different names (e.g.  full name on some Trust Unit  certificates
and  initials  and  surname  on other  Trust  Unit  certificates),  a  separate
participation  form must be completed for each different  registration name. If
distributions  from all Trust  Unit  holdings  are to be  reinvested  under one
account, the registration names must be identical.

Any Trust  Units  acquired  outside  of the Plan  which are not  registered  in
exactly the same name or manner as Trust Units enrolled in the Plan will not be
automatically  enrolled in the Plan.  If you  purchase  additional  Trust Units
outside of the Plan,  you are  advised to contact the Plan Agent to ensure that
all Trust Units you own are enrolled in the Plan.

Your  participation  in the  Plan  in  respect  of  the  reinvestment  of  cash
distributions  will  commence as of the Record Date for any given  Distribution
Date  following  receipt  by the Plan Agent of a duly  completed  participation
form,  provided  that,  the Plan  Agent  received  the form no later  than five
business days immediately preceding the Record Date.

If you sell or transfer  Trust Units that were  previously  registered  in your
name,  the  reinvestment  of  distributions  will cease in respect of the Trust
Units  that have been sold or  transferred.  Participation  in the Plan will be
terminated upon receipt by the Plan Agent of evidence  satisfactory to the Plan
Agent  and  the  Manager  of the  death  of a  participant.  In  such  case,  a
certificate  for the whole Trust  Units in the  participant's  account  will be
issued  in the name of the  estate of the  deceased  participant  along  with a
cheque representing payment for any fraction of a Trust Unit in the account and
the  return of any  uninvested  optional  cash  payments  to the  estate of the
deceased  participant.  Requests for issuance of a certificate and/or a payment
for a  fractional  Trust Unit in the name of an estate must be  accompanied  by
appropriate documentation.

OPTIONAL TRUST UNIT PURCHASES PURSUANT TO THE PLAN

Additionally,  participants  are  eligible  to make  cash  investments  through
optional cash payments  which will be invested in Trust Units by the Plan Agent
on the same basis as provided in the Plan for  distributions.  Participants may
invest up to the Maximum  Contribution Amount or the Maximum U.S.  Contribution
Amount, as applicable, through such optional cash payments.


                                      13


If you are a  registered  owner of Trust  Units,  and  wish to  invest  through
optional cash payments, the Plan Agent should receive the participation form no
later than 5:00 p.m.  (E.S.T.) on or before the Distribution Date to which such
distribution relates.

METHOD OF PURCHASE

Under the terms of the Plan, you may direct the Plan Agent to reinvest all cash
distributions,  net of withholding  taxes, if any, on Trust Units registered or
held in your name to purchase new Trust Units.  Cash  distributions  payable on
Trust Units  registered for a participant in the Plan,  after  deduction of any
applicable  withholding  tax,  will be  paid  to the  Plan  Agent  and  applied
automatically  by the Plan Agent on each  Distribution  Date to the purchase of
Trust Units for that participant. Cash investments will be similarly applied by
the Plan Agent towards purchases of Trusts Units for that participant. The Plan
Agent will  credit  the  additional  Trust  Units to the  participant's  or its
nominee's account.

PURCHASE PRICE

The Plan Agent shall purchase Trust Units from treasury at a purchase price per
Trust Unit  equal to the  weighted  average  closing  price of all Trust  Units
traded on the TSX for each of the 20 days immediately  preceding the applicable
Distribution Date, less 5%.

FRACTIONAL TRUST UNITS

A participant's  pro rata entitlement to Trust Units purchased  pursuant to the
Plan may result in the participant holding a fraction of a Trust Unit. The Plan
Agent  will pay cash  adjustment  for any such  fractional  Trust Unit upon the
withdrawal or termination by the participant of his or her participation in the
Plan or upon termination of the Plan.

ADMINISTRATION

The Trust has  entered  into an  agreement  dated  June 15,  2007 with the Plan
Agent.  The Plan  Agent  will  administer  the Plan for the  participants.  Its
responsibilities include:

o    effecting participation in the Plan by participants upon receipt of a duly
     completed participation form;

o    maintaining an account for each participating Unitholder;

o    receiving eligible funds;

o    purchasing  and  crediting the Trust Units  accumulated  under the Plan to
     each participant's account;

o    sending  statements of accounts to the  participants  approximately  three
     weeks after each investment; and

o    other duties required by the Plan or necessary or desirable to fulfill the
     aims of the Plan.


                                      14


PARTICIPANTS' ACCOUNTS AND REPORTS

The Plan  Agent will  maintain  an account  for each  participating  registered
Unitholder  in this Plan.  A  statement  of account  will be mailed by the Plan
Agent to each participating  registered  Unitholder  approximately  three weeks
after each  investment,  whether monthly or quarterly.  This statement will set
out the amount of the cash  distributions,  net of any withholding tax, paid on
the participant's  Trust Units for the relevant period, the total amount of any
optional cash payments  received from this participant  during the period,  the
number of additional  Trust Units  purchased  through this Plan for the period,
the dates of these purchases,  the applicable purchase price per Trust Unit and
the updated total number of Trust Units being held for the  participant in this
Plan.  These  statements are a participant's  continuing  record of the cost of
purchases and should be kept for tax purposes.  In addition,  each  participant
will receive the appropriate  information annually for reporting  distributions
for tax purposes.

FEDERAL ANTI-TERRORISM AND ANTI-MONEY LAUNDERING LEGISLATION

Federal  anti-terrorism  and anti-money  laundering  legislation  requires that
participants  wishing to make optional cash payments  provide certain  personal
information.  If an optional cash payment is being made,  participants  will be
required to complete the Optional Cash Purchase - Participant  Declaration Form
and submit to the Plan Agent with their completed  Enrollment and Authorization
Form.

TRUST UNIT CERTIFICATES

Generally,  certificates for new Trust Units purchased through the Plan will be
held for  participants  and reported on the statement of account.  This service
protects  against  loss,  theft  or  destruction  of Trust  Unit  certificates.
However,  participants who require a Trust Unit certificate but who do not wish
to terminate  participation in the Plan may obtain a certificate for any number
of whole  Trust  Units held in their  account  by  written  request to the Plan
Agent. A certificate will not be issued for a fraction of a Trust Unit.

Plan accounts are maintained in the names in which certificates were registered
with the Trust at the time the participant enrolled in the Plan.  Consequently,
certificates  for whole Trust Units  withdrawn from the Plan will be registered
in exactly the same manner when issued.

Trust Units being held for a participant  in the Plan may not be pledged,  sold
or otherwise disposed of by a participant.  The participant who wishes to do so
must submit a withdrawal request with the Plan Agent. If the withdrawal request
form is not  received  by the Plan Agent at least five  business  days before a
Record Date, it will not be processed  until after the next investment has been
completed. A withdrawal request form may be obtained from the Plan Agent at the
address provided under "Notices" below.  Certificates  will generally be issued
to a  participant  within  three  weeks of  receipt  by the  Plan  Agent of the
withdrawal  request.  Certificates  will not be issued for fractions of a Trust
Unit. Please note that cash distributions on the certificated Trust Units will,
until  such  Trust  Units are sold or  otherwise  transferred,  continue  to be
reinvested  under  this Plan,  as will cash  distributions  on any Trust  Units
remaining in the participant's account.

COMMISSIONS AND ADMINISTRATIVE COSTS

There  is no  charge  to  participants  for  reinvesting  distributions  or for
investing  optional cash payments  pursuant to this Plan. The Plan Agent's fees
for reinvesting  distributions and for investing optional cash payments will be
paid by the Trust.  No brokerage  charges will be incurred  with respect to the
issuance of Trust Units from  treasury  for  reinvesting  distributions  or for


                                      15


investing optional cash payments. However,  Unitholders who enroll in this Plan
through a broker,  trust company,  bank or other nominee may be subject to fees
in accordance with their agreement with their nominee.

RESPONSIBILITIES OF THE TRUST, THE CORPORATION AND THE PLAN AGENT

Neither we, the Corporation nor the Plan Agent shall be liable for any act done
in good  faith or for any  good  faith  omission  to act.  Participants  should
recognize that neither we, the Corporation nor the Plan Agent can assure a gain
or protect against loss as a result of their holding Trust Units.

TERMINATION OF PARTICIPATION

Plan  participants  may, after  electing to participate in the Plan,  terminate
their  participation  in the Plan,  in the case of registered  Unitholders,  by
providing written  termination  notice to the Plan Agent at least five business
days immediately  preceding the Record Date for the next  distribution.  If the
termination  form is not received by the Plan Agent at least five business days
immediately  preceding the Record Date to which such distribution relates, your
participation in the Plan will continue in the usual manner and the termination
will be effective for the next distribution.

Upon  termination of  participation in the Plan, the Plan Agent will as soon as
practicable  (and in any event within three weeks of receipt of the termination
notice or within  three  weeks  after the next  Distribution  Date)  settle the
participant's  account by transferring the  participant's  Trust Units to or to
the order of such participant and, if applicable, issue a cheque representing a
cash adjustment for fractional Trust Units.

UNITHOLDER VOTING

For any meeting of  Unitholders,  you will receive proxy  materials in order to
vote all Trust Units held for your  account.  Your Trust Units will be voted as
you direct or you may vote by proxy or in person at the meeting of Unitholders.
A fractional Trust Unit does not carry the right to vote.

         AMENDMENTS, SUSPENSION OR TERMINATION OF PLAN AND PLAN AGENT

The Trust  reserves the right to amend,  suspend or terminate  this Plan at any
time,  but such action shall have no retroactive  effect which would  prejudice
the  interests of the  participants.  Without  limiting the  generality  of the
foregoing,  the Trust may suspend or  terminate  this Plan with  respect to the
residents of any  jurisdiction in which  compliance with applicable  securities
laws would be, in the sole judgment of the Manager of the Trust,  impracticable
or unduly expensive. Any amendment to this Plan must be pre-cleared by the TSX.
Participants  will be sent written notice of any such amendment,  suspension or
termination  that  affects  them.  If this  Plan is  terminated  by the  Trust,
participants  will  receive a  certificate  registered  in their name for whole
Trust  Units  being held for them,  a cheque in payment  for any  fraction of a
Trust Unit and the return of any uninvested optional cash payments.

NOTICES

All notices required to be given to participants  will be mailed to them at the
address shown on the records of the Plan Agent.

                 INCOME TAX CONSIDERATIONS RELATING TO THE PLAN

The following  summary of tax  consequences  is of a general nature only and is
not intended to be legal or tax advice to any particular participant. It is the
responsibility  of  participants  in the Plan to consult their own tax advisors
with  respect to the tax  consequences  of  participation  in the Plan in their
respective country of residence.

CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

The  following  is a summary  of the  principal  Canadian  federal  income  tax
considerations  generally  applicable to a participant in the Plan who, for the
purposes of the Income Tax Act (Canada) (the "Tax Act") and any  applicable tax
treaty,  and at all relevant times, is not resident or deemed to be resident in
Canada,  does not use or hold  (and is not  deemed  under the Tax Act to use or
hold)  Trust  Units in, or in the course of,  carrying on a business in Canada,
and is not an  insurer  who  carries  on an  insurance  business  in Canada and
elsewhere (a "Non-Resident Unitholder").

This  summary  is based  upon  the  current  provisions  of the Tax Act and the
regulations  thereunder  (the  "Regulations"),  the current  provisions  of the
Canada-United  States Tax Convention,  1980 (the "Canada-U.S.  Tax Treaty") and
our  understanding  of  the  current  published  administrative  and  assessing
practices of the Canada  Revenue  Agency.  This summary also takes into account
all  specific  proposals  to  amend  the Tax Act and the  Regulations  publicly
announced by or on behalf of the Minister of Finance (Canada) prior to the date
hereof (the "Proposed  Amendments").  This summary does not otherwise take into
account or anticipate any changes in law, whether by judicial,  governmental or
legislative  action,  or in  administrative  practice,  nor  does it take  into


                                      17


account provincial or territorial laws of Canada or the tax laws of any foreign
country.  No  assurances  can be given  that the  Proposed  Amendments  will be
enacted as proposed, or at all, or that legislative, judicial or administrative
changes  will not modify or change the  statements  expressed  herein after the
date of the Plan.

On October 31, 2006, the federal Minister of Finance ("Finance")  announced new
proposals  (the  "October 31  Proposals")  that,  if enacted,  would change the
manner  in which  certain  flow-through  entities,  referred  to as  "specified
investment  flow-through"  entities or "SIFTs", and the distributions from such
entities are taxed.  In their current form,  the October 31 Proposals  will not
apply to SIFTs that were  publicly  traded on October 31, 2006  ("Grandfathered
SIFTs") until January 1, 2011. However,  the October 31 Proposals indicate that
any "undue  expansion"  of a  Grandfathered  SIFT between  October 31, 2006 and
January  1, 2011 (the  "Interim  Period"),  may  cause the  application  of the
October 31 Proposals to the Grandfathered SIFT to occur before January 1, 2011.

Following the October 31, 2006 announcement,  Finance issued a press release on
December  15,  2006  wherein  it  provided   guidelines   (the  "Normal  Growth
Guidelines")  as to what  would be  considered  "normal  growth"  as opposed to
"undue expansion" of a SIFT trust. On December 21, 2006,  Finance also released
draft   legislation   to  implement  the  October  31  Proposals   (the  "Draft
Legislation")  and invited  commentary  on the  technical  aspects of the Draft
Legislation  prior to January 31, 2007. On March 19, 2007,  Finance  introduced
Bill C-52 into the Canadian House of Commons, which incorporates the October 31
Proposals.  Bill C-52 has  received  third and  final  reading  in the House of
Commons but is not yet law.

Provided  that  the  Trust  is not  considered  to  have  undergone  an  "undue
expansion"  during  the  Interim  Period,  as  set  out in  the  Normal  Growth
Guidelines,  Bill C-52, if enacted in its current form,  will change the manner
in which the Trust and its  distributions  are taxed beginning January 1, 2011.
More  specifically,  the Trust will be subject to entity level taxation,  which
will reduce the amount of cash available for  distribution to the  Unitholders.
Based on the proposed  rate of entity level  taxation,  the tax rate on certain
income  distributed by the Trust to its Unitholders  would  approximate the tax
rate  applicable  to a  taxable  Canadian  corporation.  Based  on  information
released by Finance in conjunction with the October 31 Proposals,  the proposed
tax rate in 2011 will be 31.5% which is comprised of an 18.5% federal tax and a
13% tax rate on account of provincial  tax. It is assumed,  for the purposes of
this  summary,  that the Trust will not be subject to the October 31  Proposals
until January 1, 2011.

Under the existing provisions of the Tax Act, any distribution of income by the
Trust to a Non-Resident  Unitholder will be subject to Canadian withholding tax
at the rate of 25%  unless  such  rate is  reduced  under the  provisions  of a
convention  between Canada and the  Non-Resident  Unitholder's  jurisdiction of
residence.  A  Non-Resident  Unitholder  resident  in the United  States who is
entitled to claim the benefit of the Canada-U.S.  Tax Treaty, will generally be
entitled  to have the rate of  withholding  reduced to 15% of the amount of any
income distributed.

Pursuant to the October 31 Proposals,  amounts in respect of the Trust's income
payable to Non-Resident  Unitholders  that are not deductible to the Trust will
be treated as a taxable  dividend  from a taxable  Canadian  corporation.  Such
dividends will be subject to Canadian  withholding tax at a rate of 25%, unless
such rate is reduced under the  provisions of a convention  between  Canada and
the  Non-Resident   Unitholder's  jurisdiction  of  residence.  A  Non-Resident


                                      18


Unitholder  resident in the United  States who is entitled to claim the benefit
of the  Canada-U.S.  Tax Treaty  generally will be entitled to have the rate of
withholding reduced to 15% of the amount of such dividend. Although the October
31 Proposals may not increase the tax payable by  Non-Resident  Unitholders  in
respect of dividends  deemed to be paid by the Trust,  it is expected  that the
imposition  of tax at the Trust  level  under the  October  31  Proposals  will
materially   reduce  the  amount  of  cash  available  for   distributions   to
Unitholders.

Returns of capital to a Unitholder who is not a resident of Canada for purposes
of the Tax Act or is a  partnership  that is not a "Canadian  partnership"  for
purposes  of the Tax Act are,  and  will be under  the  October  31  Proposals,
subject to a 15% Canadian withholding tax.

It is not  certain  whether  the amount by which the fair  market  value of the
Trust Units  received by a Non-Resident  Unitholder on a  reinvestment  of cash
distributions  pursuant to the Plan  exceeds the amount of the cash  reinvested
(that is, the 5%  discount)  is  subject to this 15%  withholding  tax.  In the
event the Trust  determines  that it is, the Trust will  withhold  such tax and
remit it to the Canadian government.

As a consequence of these withholding  taxes, the amount that may be reinvested
in the  Plan by a  Non-Resident  Unitholder,  and the  number  of  Trust  Units
received by a Non-Resident  Unitholder on a reinvestment of cash distributions,
will be reduced by the amount of the taxes  withheld.  It is also expected that
the amount of cash  distributions  available to reinvest in Trust Units will be
reduced by the 31.5% entity level tax applicable to the Trust.

Generally,  subject to the comments in the next paragraph with respect to an in
specie  redemption  of Trust  Units,  no  Canadian  taxes  will be payable by a
Non-Resident  Unitholder  in  respect  of a  disposition,  whether  by  way  of
redemption  or  otherwise,  by the  Non-Resident  Unitholder  of  Trust  Units,
provided the Trust Units do not constitute  "taxable Canadian property" (within
the meaning of the Tax Act) to the Non-Resident  Unitholder.  Generally,  Trust
Units  will  not  constitute   taxable  Canadian  property  to  a  Non-Resident
Unitholder at a particular time provided the Non-Resident  Unitholder,  persons
with whom the Non-Resident Unitholder does not deal at arm's length (within the
meaning of the Tax Act),  or the  Non-Resident  Unitholder  together  with such
persons  did not own 25% or more of the issued  Trust  Units at any time during
the 60 month period that ends at that  particular  time,  and provided  further
that the Trust qualifies as a "mutual fund trust" under the Tax Act at the time
of the disposition.

If a Non-Resident  Unitholder  requests a redemption of his or her Trust Units,
the Non-Resident Unitholder may, as a consequence, receive a direct interest in
the  royalty,  and  shares  and  notes  of the  Corporation  or  certain  other
subsidiaries  of  the  Trust.   The  Canadian  income  tax  consequences  to  a
Non-Resident  Unitholder  of owning and  disposing of such  securities  are not
described herein.  Non-Resident  Unitholders are urged to consult their own tax
advisors before requesting a redemption of their Trust Units.

                UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a general  description  of the material  United States federal
income tax  consequences  of the ownership and  disposition of Trust Units to a
Unitholder  who  participates  in the  Plan.  This  discussion  is based on the
Internal  Revenue  Code  of  1986,  as  amended  (the  "Code"),  administrative


                                      19


pronouncements, judicial decisions, existing and proposed Treasury regulations,
and  interpretations  of the foregoing,  all as of the date hereof.  All of the
foregoing authorities are subject to change (possibly with retroactive effect),
and any such change may result in United States federal income tax consequences
to a Unitholder that are materially  different from those  described  below. No
rulings from the United States  Internal  Revenue Service (the "IRS") have been
or  will  be  sought  with  respect  to  the  matters   described   below,  and
consequently, the IRS may not take a similar view of the consequences described
below.

The  following  discussion  does not  purport to be a full  description  of all
United  States  federal  income tax  considerations  that may be  relevant to a
United  States  holder  (as  defined  below)  in  light  of  such  Unitholder's
particular circumstances and only addresses Unitholders who hold Trust Units as
capital  assets  within the meaning of Section  1221 of the Code.  Furthermore,
this  discussion  does  not  address  the  United  States  federal  income  tax
considerations  applicable to Unitholders subject to special rules, such as (i)
persons that are not United States holders, (ii) certain financial institutions
or  insurance  companies,  (iii) real  estate  investment  trusts or  regulated
investment  companies,   (iv)  traders  in  securities  that  elect  to  use  a
mark-to-market method of accounting or dealers in securities or currencies, (v)
persons  holding notes in connection  with a hedging  transaction,  "straddle,"
conversion transaction or a synthetic security or other integrated transaction,
(vi) Unitholders whose  "functional  currency" is not the United States dollar,
(vii)  persons  subject  to  the  alternative  minimum  tax,  and  (viii)  U.S.
expatriates.  In addition,  except as otherwise indicated, this discussion does
not include any description of any estate and gift tax consequences, or the tax
laws of any state, local or foreign government that may be applicable.

As used herein,  the term "United States holder" means a beneficial  owner of a
Trust Unit that is (i) an individual  citizen or resident of the United States,
(ii) a corporation  or other entity  taxable as a  corporation  organized in or
under the laws of the United States or any political subdivision thereof, (iii)
an estate  the  income of which is  subject  to United  States  federal  income
taxation  without regard to the source or (iv) a trust if a United States court
has primary  supervision over its  administration and one or more United States
persons have the authority to control all  substantial  decisions of the trust,
or if the  trust  has a valid  election  in effect  under  applicable  Treasury
Regulations to be treated as a United States person.

If a  partnership  (or an entity  taxable as a  partnership  for United  States
federal income tax purposes)  holds our Trust Units,  the United States federal
income tax  treatment of a partner  generally  will depend on the status of the
partner and the activities of the partnership. A United States person that is a
partner of a  partnership  (or an entity  taxable as a  partnership  for United
States federal income tax purposes)  holding our Trust Units should consult its
own tax advisors.

UNITED  STATES  HOLDERS  SHOULD  CONSULT  THEIR TAX ADVISORS WITH REGARD TO THE
APPLICATION  OF  UNITED  STATES  FEDERAL  INCOME  TAX LAWS TO THEIR  PARTICULAR
SITUATIONS,  AS WELL AS ANY TAX  CONSEQUENCES  ARISING  UNDER  THE  LAWS OF ANY
STATE, LOCAL OR FOREIGN TAXING JURISDICTION.

CLASSIFICATION OF THE TRUST AS A PARTNERSHIP

We have  elected  under  applicable  Treasury  Regulations  to be  treated as a
partnership for United States federal income tax purposes. Although there is no


                                      20


plan or  intention  to do so,  we have  the  right to  elect  under  applicable
Treasury  Regulations to be treated as a corporation  for United States federal
income tax purposes, if such election was determined to be beneficial.

A partnership generally is not treated as a taxable entity and incurs no United
States federal income tax liability.  Instead, as discussed below, each partner
in an entity treated as a partnership for tax purposes is required to take into
account its allocable share of items of income, gain, loss and deduction of the
partnership  in  computing  its United  States  federal  income tax  liability,
regardless of whether cash or other distributions are made.  Distributions by a
partnership  to a partner are  generally  not taxable  unless the amount of any
cash  distributed  is  in  excess  of  the  partner's  adjusted  basis  in  its
partnership interest (see "Tax Consequences of Trust Unit Ownership - Treatment
of  Distributions").  Each Unitholder will be treated as a partner in the Trust
for United States federal income tax purposes.

Section 7704 of the Code provides that publicly-traded partnerships such as the
Trust will, as a general rule, be taxed as corporations.  However, an exception
(the  "Qualifying  Income  Exception")  exists with respect to  publicly-traded
partnerships  of which 90% or more of the gross  income for every  taxable year
consists of "qualifying  income."  Qualifying  income  includes  interest (from
other than a financial business),  dividends, rents from real property, oil and
gas royalty income,  gains from the sale of oil and gas  properties,  and gains
derived from the exploration,  development,  mining or production,  processing,
refining,  transportation  or the  marketing  of oil and  gas.  Royalty  income
received  by the Trust from the  Corporation  should be  treated as  qualifying
income.  The Trust  believes  that less than 10  percent  of its income for the
current year will not be qualifying  income and that it has met the  qualifying
income  exception  since it first  elected to be treated as a  partnership  for
United States  federal  income tax purposes in 1997.  The Trust expects that it
will continue to meet the qualifying  income  exception in 2007 and thereafter.
No assurance can be given that the qualifying  income exception will in fact be
met.

POSSIBLE CLASSIFICATION AS A CORPORATION; PFIC RULES

If we fail to meet the Qualifying  Income Exception (other than a failure which
is  determined  by the IRS to be  inadvertent  and  which  is  cured  within  a
reasonable time after  discovery),  we will be treated as if we transferred all
of our assets (subject to  liabilities)  to a newly formed  corporation (on the
first day of the year in which we fail to meet the Qualifying Income Exception)
in return for stock in that corporation, and then distributed that stock to our
owners in  liquidation  of their  interests  in us.  That deemed  transfer  and
liquidation  would likely be taxable to United States holders.  Thereafter,  we
would be treated as a  corporation  for  federal  income tax  purposes.  United
States  holders  would be  required  to file IRS Form 926 to report  the deemed
transfer  and any other  transfers  made to the Trust  while it is treated as a
corporation.

If we were treated as a corporation in any taxable year,  either as a result of
a failure to meet the Qualifying  Income  Exception or otherwise,  our items of
income,  gain,  loss and deduction would not be passed through to United States
holders.  Instead,  United  States  holders  would be taxed upon the receipt of
distributions,  either  pursuant  to the  passive  foreign  investment  company
("PFIC") rules discussed below or, if those rules are not applicable (or if the
United  States  holder makes certain  elections  pursuant to those  rules),  as
either  taxable  dividend  income (to the extent of our current or  accumulated
earnings  and profits  calculated  by  reference to our tax basis in our assets
without  regard to the price paid for Trust Units by  subsequent  United States


                                      21


holders) or (in the absence of earnings  and  profits) a  nontaxable  return of
capital  (to the extent of the United  States  holder's  tax basis in its Trust
Units) or taxable  capital gain (after the United States  holder's tax basis in
the Trust Units is reduced to zero). If we were treated as a corporation, it is
possible  that we would be  considered  a PFIC,  in which  case  special  rules
(discussed  below),  potentially quite adverse to United States holders,  would
apply.

CONSEQUENCES OF POSSIBLE PFIC CLASSIFICATION

A non-United  States entity treated as a corporation  for United States federal
income tax purposes  will be a PFIC in any taxable year in which,  after taking
into account the income and assets of the corporation and certain  subsidiaries
pursuant to the applicable "look through" rules, either (1) at least 75 percent
of its gross income is "passive"  income (the "income test") or (2) at least 50
percent of the  average  value of its  assets is  attributable  to assets  that
produce  passive  income or are held for the  production of passive income (the
"assets test").

The Trust currently believes that, if classified as a corporation, it would not
be a PFIC.  Because PFIC status is fundamentally  factual in nature,  generally
cannot be  determined  until the close of the taxable  year in question  and is
determined  annually,  no assurance  can be given that the Trust,  if it were a
corporation, would not be now, and would not be in the future, a PFIC.

If we were  classified  as a PFIC,  for any year during  which a United  States
holder owns Trust Units,  the United States holder will generally be subject to
special rules  (regardless of whether we continue to be a PFIC) with respect to
(1) any "excess  distribution"  (generally,  any  distribution  received by the
United  States holder on Trust Units in a taxable year that is greater than 125
percent of the  average  annual  distributions  received  by the United  States
holder in the three preceding  taxable years or, if shorter,  the United States
holder's holding period for the Trust Units) and (2) any gain realized upon the
sale or other disposition of Trust Units. Under these rules:

o    the excess  distribution or gain will be allocated ratably over the United
     States holder's holding period;

o    the amount allocated to the current taxable year and any year prior to the
     first year in which we were a PFIC will be taxed as ordinary income in the
     current year;

o    the  amount  allocated  to each of the other  taxable  years in the United
     States holder's  holding period will be subject to tax at the highest rate
     of tax in effect for the applicable class of taxpayer for that year; and

o    an interest  charge for the deemed  deferral  benefit will be imposed with
     respect to the resulting tax attributable to each such other taxable year.

A United  States  holder would also  generally be subject to similar rules with
respect to  distributions to us by, and dispositions by us of the stock of, any
direct or indirect subsidiary of the Trust that is also a PFIC.

Certain  elections  may be  available  to a  United  States  holder  if we were
classified as a PFIC. We will provide  United States  holders with  information
concerning the potential  availability  of such elections if it determines that
it is or will become a PFIC.


                                      22


The discussion  below is based on the  assumption  that we will be treated as a
partnership for United States federal income tax purposes.

TAX CONSEQUENCES OF PLAN PARTICIPATION

AMOUNT CAPABLE OF INCLUSION IN INCOME

For United States federal income tax purposes,  a United States holder who is a
participant  in the Plan will be treated as receiving a  distribution  equal to
the sum of (i) the fair market value as of the Distribution Date of Trust Units
acquired  pursuant to the Plan,  and (ii) any Canadian  taxes which we withhold
with respect to the  distribution.  Distributions by a partnership to a partner
are  generally  not  taxable  unless the amount of any cash  distributed  is in
excess of the partner's  adjusted basis in his  partnership  interest (see "Tax
Consequences of Trust Unit Ownership - Treatment of Distributions" below).

BASIS AND HOLDING PERIOD

The amount paid for the Trust Units will be added to the  adjusted tax basis of
a United States holder in its interest in us. The holding period of Trust Units
generally  should begin on the day after the  distribution  payment date. For a
discussion of basis recovery and the  determination of holding periods of Trust
Units if Trust Units are sold, including if a portion of a holder's Trust Units
are sold, see "Disposition of - Recognition of Gain or Loss" below.

TAX CONSEQUENCES OF TRUST UNIT OWNERSHIP

FLOW-THROUGH OF TAXABLE INCOME

Each United  States  holder will be required to report on its income tax return
its  allocable  share  (based on the  percentage  of Trust  Units owned by that
United  States  holder) of our income,  gains,  losses and  deductions  for the
taxable  year of the Trust ending with or within the taxable year of the United
States holder without regard to whether  corresponding  cash  distributions are
received by such United States holder. Consequently, a United States holder may
be  allocated  income  from  the  Trust  even  if it has  not  received  a cash
distribution from us.

We intend to make available to each United States holder,  within 75 days after
the close of each calendar year, a Substitute Schedule K-1 containing his share
of our income, gain, loss and deduction for the preceding Trust taxable year.

We treat the Royalty between us and the  Corporation as a royalty  interest for
all legal purposes,  including  United States federal income tax purposes.  The
indenture  pursuant  to which  the  Royalty  is  paid,  the  royalty  indenture
("Royalty  Indenture")  in some respects  differs from more  conventional  "net
profits"  interests  as to which the  courts and the IRS have  ruled,  and as a
result the propriety of such  treatment is not free from doubt.  It is possible
that the IRS could contend, for example, that the Trust should be considered to
have a working interest in the properties of the  Corporation.  If the IRS were
successful in making such a contention,  the United States  federal  income tax
consequences  to United States holders could be different,  perhaps  materially
worse,  than indicated in the discussion  herein,  which generally assumes that
the Royalty Indenture will be respected as a royalty.


                                      23


TREATMENT OF DISTRIBUTIONS

Distributions  by us to a United States holder generally will not be taxable to
the United States  holder for federal  income tax purposes to the extent of its
tax  basis  in its  Trust  Units  immediately  before  the  distribution.  Cash
distributions in excess of a United States holder's tax basis generally will be
considered to be gain from the sale or exchange of the Trust Units,  taxable in
accordance with the rules described under "--Disposition of Trust Units" below.

BASIS OF TRUST UNITS

A United  States  holder's  initial  tax basis for its Trust  Units will be the
amount paid for the Trust  Units.  That basis will be increased by its share of
our income and decreased (but not below zero) by  distributions  to it from us,
by the United States  holder's share of our losses and  deductions,  and by its
share of our  expenditures  that are not  deductible  in computing  our taxable
income and are not  required to be  capitalized.  See  "--Disposition  of Trust
Units--Recognition of Gain or Loss".

LIMITATIONS ON DEDUCTIBILITY OF LOSSES

There are  limitations  on the ability of a United  States holder to deduct any
Trust  losses  under the basis  limitation  rules,  the  at-risk  rules and the
passive  loss rules.  Special  passive  loss rules  apply to a publicly  traded
partnership such as the Trust.

It is not anticipated that we will generate losses. Nevertheless, should losses
result,  United States  holders should consult their own tax advisors as to the
applicability to them of such loss limitations.

LIMITATIONS ON INTEREST DEDUCTIONS

The deductibility of a non-corporate  taxpayer's "investment interest expenses"
is generally limited to the amount of such taxpayer's "net investment  income."
Investment  interest  expense  includes (i) interest on  indebtedness  properly
allocable  to  property  held for  investment  and (ii) the portion of interest
expense  incurred to purchase or carry an interest in a passive activity to the
extent  attributable  to portfolio  income.  The computation of a United States
holder's  investment  interest  expense will take into account  interest on any
margin account borrowing or other loan incurred to purchase or own Trust Units.
Net investment  income  includes gross income from property held for investment
and amounts treated as portfolio income pursuant to the passive loss rules less
deductible   expenses  (other  than  interest)   directly  connected  with  the
production  of  investment   income,  but  generally  does  not  include  gains
attributable to the disposition of property held for investment.

FOREIGN TAX CREDITS

Subject to certain limitations set forth in the Code, United States holders may
elect to  claim a  credit  against  their  United  States  federal  income  tax
liability for net Canadian income tax withheld from  distributions  received in
respect of the Trust Units that is not  refundable to the United States holder.
United  States  holders will also be entitled to claim a foreign tax credit for
any Canadian  income taxes paid by us. The limitation on foreign taxes eligible
for credit is calculated separately with respect to specific classes of income.
For taxable years  beginning  after  December 31, 2006,  distributions  will be
"passive  category  income"  or  "general  category  income"  for  purposes  of
computing the foreign tax credit  allowable to a United  States holder  (United


                                      24


States holders with tax years  beginning  before January 1, 2007 should consult
their own tax  advisors  regarding  applicable  limitations).  The  October  31
Proposals, if enacted, would apply a tax at the Trust level on distributions of
certain  income  from a  SIFT  trust.  It is  unclear  whether  this  tax  will
constitute an income tax or a tax imposed "in lieu" thereof for purposes of the
foreign tax credit rules;  if it does not constitute  such a tax it will not be
creditable.  The rules and  limitations  relating to the  determination  of the
foreign tax credit are complex and prospective  purchasers are urged to consult
their own tax  advisors  to  determine  whether or to what extent they would be
entitled  to such  credit.  United  States  persons  that do not elect to claim
foreign tax credits may instead  claim a deduction  for their share of Canadian
income taxes paid by us or withheld from distributions by us.

TAX TREATMENT OF TRUST OPERATIONS

ACCOUNTING METHOD AND TAXABLE YEAR

We use the year ending  December 31 as its  taxable  year and have  adopted the
accrual method of accounting for United States federal income tax purposes.

DEPLETION

Under the Code, a United States holder may deduct in its United States  federal
income tax return a cost depletion  allowance with respect to the Royalty Units
issued by the  Corporation  to the Trust.  United  States  holders must compute
their own depletion allowance and maintain records of the adjusted basis of the
Royalty Units for depletion and other purposes. We, however,  intend to furnish
each United States holder with information relating to this computation.

Cost  depletion is calculated  by dividing the adjusted  basis of a property by
the total  number of units of oil or gas expected to be  recoverable  therefrom
and then  multiplying  the  quotient by the number of units of oil and gas sold
during the year.  Cost depletion,  in the aggregate,  cannot exceed the initial
adjusted basis of the property. In this connection,  we intend to utilize a tax
election, known as a Section 754 election and discussed below, which will allow
purchasers  of Trust Units to be entitled to  depletion  deductions  based upon
their purchase price for the Trust Units.

The  depletion  allowance  must be computed  separately  by each United  States
holder for each oil and gas property,  within the meaning of Section 614 of the
Code.  The IRS is  currently  taking the position  that a net profits  interest
carved from multiple  properties is a single  property for depletion  purposes.
The Royalty Indenture burdens multiple  properties.  Accordingly,  we intend to
take  the  position  that  the  properties  subject  to the  Royalty  Indenture
constitute a single property for depletion purposes and the income from the net
profits  interest  will be  royalty  income  qualifying  for an  allowance  for
depletion.  We  anticipate  that we would change this  position if it should be
determined  that a different  method of computing  the  depletion  allowance is
required by law.

DEPRECIATION

The tax basis of the various  depreciable  assets of the Trust will be used for
purposes  of  computing   depreciation   and  cost  recovery   deductions  and,
ultimately, gain or loss on the disposition, of such assets.


                                      25


VALUATION OF OUR PROPERTIES

Certain of the United States federal income tax  consequences  of the ownership
and  disposition  of Trust  Units will depend in part on our  estimates  of the
relative fair market value of our assets.  Although we may consult from time to
time with professional  appraisers  regarding  valuation matters,  we will make
many of the relative fair market value  estimates.  These estimates are subject
to challenge and will not be binding on the IRS or the courts. If the estimates
of fair market value are later found to be incorrect,  the character and amount
of items of income,  gain,  loss or  deductions  previously  reported by United
States  holders  might change,  and United States  holders might be required to
adjust their tax  liability  for prior years and incur  interest and  penalties
with respect to those adjustments.

SECTION 754 ELECTION

We have made the election  permitted by Section 754 of the Code.  That election
is irrevocable  without the consent of the IRS. The election generally requires
us, in the case of a sale of the Trust Units in the secondary market, to adjust
the purchaser's tax basis in the assets of the Trust pursuant to Section 743(b)
of the Code to reflect the purchaser's  purchase price of its Trust Units.  The
Section 743(b) adjustment belongs to the purchaser and not to other partners.

A Section 754  election is  advantageous  if the  purchaser's  tax basis in its
Trust Units is higher than its share of the aggregate tax basis to the Trust of
the assets of the Trust immediately prior to the purchase. In such a case, as a
result of the  election,  the  purchaser  would  have a higher tax basis in its
share of the  assets of the Trust for  purposes  of  calculating,  among  other
things,  depletion  and  depreciation.  Conversely,  a Section 754  election is
disadvantageous  if the purchaser's tax basis in such Trust Units is lower than
its share of the  aggregate  tax basis of the  assets of the Trust  immediately
prior to the  transfer.  Thus,  the fair market value of the Trust Units may be
affected either favorably or adversely by the election.

DISPOSITION OF TRUST UNITS

RECOGNITION OF GAIN OR LOSS

Gain  or  loss  will  be  recognized  on a sale of  Trust  Units  equal  to the
difference between the amount realized and the United States holder's tax basis
for the Trust Units sold.  Gain or loss recognized by a United States holder on
the sale or exchange of Trust Units will  generally  be taxable as capital gain
or loss,  and will be  long-term  capital  gain or loss if such  United  States
holder's  holding  period of the Trust Units exceeds one year. In the case of a
non-corporate  United States holder,  any such  long-term  capital gain will be
subject to tax at a reduced rate.

A portion of any amount  realized on a sale or  exchange of Trust Units  (which
portion could be substantial) will be separately computed and taxed as ordinary
income  under  Section  751  of the  Code  to the  extent  attributable  to the
recapture of depletion or depreciation deductions. Ordinary income attributable
to depletion  deductions and  depreciation  recapture  could exceed net taxable
gain realized  upon the sale of the Trust Units and may be  recognized  even if
there is a net taxable loss  realized on the sale of the Trust  Units.  Thus, a
United States holder may recognize both ordinary income and a capital loss upon
a  taxable  disposition  of  Trust  Units.  Certain  limitations  apply  to the
deductibility of capital losses.


                                      26


The IRS has ruled that a person who acquires  interests  in an entity,  such as
the Trust,  which is treated as a partnership  for United States federal income
tax purposes in separate  transactions  at different  prices must combine those
interests  and  maintain  a single  adjusted  tax  basis.  Upon a sale or other
disposition  of less than all of those  interests,  a portion of that tax basis
must  be  ratably  allocated  to the  interests  sold  and  retained  using  an
"equitable  apportionment" method. Although the ruling is unclear as to how the
holding  period  of these  interests  is  determined  once  they are  combined,
regulations  allow a seller of such an interest  who can  identify the interest
sold with an ascertainable  holding period to elect to use that holding period.
Thus,  according to the ruling, a United States holder will be unable to select
high or low basis Trust Units to sell as would be the case with corporate stock
but, according to the regulations,  may designate Trust Units sold for purposes
of  determining  the holding  period of the Trust Units sold.  A United  States
holder  electing to use this approach must  consistently  use that approach for
all subsequent  sales and exchanges of Trust Units. It is not clear whether the
ruling applies to the Trust because,  similar to corporate stock,  interests in
the Trust are readily ascertainable and are evidenced by separate certificates.
A United States holder  considering  the purchase of additional  Trust Units or
the sale of Trust Units purchased in separate  transactions  should consult its
own tax advisor regarding the application of this ruling and the regulations.

ALLOCATIONS BETWEEN TRANSFERORS AND TRANSFEREES

In general,  in reporting tax information for United States holders our taxable
income and losses will be  determined  annually,  will be prorated on a monthly
basis and will be subsequently  apportioned  among the United States holders in
proportion  to the  number  of Trust  Units  owned by each of them on the first
business  day of the  month  (the  "allocation  date").  However,  gain or loss
realized  on a sale or other  disposition  of Trust  assets  other  than in the
ordinary course of business,  and other extraordinary  items, will be allocated
among the United States  holders on the  allocation  date in the month in which
that gain or loss is recognized.

NOTIFICATION REQUIREMENTS

A United  States  holder  that sells or  exchanges  Trust  Units is required to
notify us in writing of that sale or exchange  within 30 days after the sale or
exchange and in any event by no later than January 15 of the year following the
calendar year in which the sale or exchange occurred. We are required to notify
the  IRS  of  that  transaction  and  to  furnish  certain  information  to the
transferor and transferee.  However,  these reporting requirements do not apply
with respect to a sale by an  individual  who is a citizen of the United States
and who  effects  the  sale or  exchange  through  a  broker.  Additionally,  a
transferor  and a  transferee  of  Trust  Units  will be  required  to  furnish
statements to the IRS, filed with its income tax return for the taxable year in
which the sale or exchange occurred,  that allocates the consideration paid for
the Trust Units.  This  information  will be provided by the Trust.  Failure to
satisfy these  reporting  obligations may lead to the imposition of substantial
penalties.

CONSTRUCTIVE TERMINATION

The Trust will be considered to have been  terminated for United States Federal
income tax  purposes if there is a sale or exchange of 50% or more of the total
Trust Units within a 12-month period. A termination of the Trust will result in
a  decrease  in  tax  depreciation  available  to  the  United  States  holders


                                      27


thereafter  and in the  closing  of its  taxable  year  for all  United  States
holders.  In the case of a United  States  holder  reporting  on a taxable year
other than a fiscal year ending December 31, the closing of the Trust's taxable
year may  result in more than 12  months'  taxable  income or loss of the Trust
being  includable in its taxable  income for the year of  termination.  New tax
elections  would have to be made by the Trust,  including a new election  under
Section 754 of the Code. Adverse tax consequences could ensue if we were unable
to determine that the termination had occurred.  Finally,  a termination of the
Trust could result in taxation of the Trust as a corporation  if the Qualifying
Income  Exception was not met in the short taxable years caused by termination.
See "--Classification of the Trust as a Partnership."

TREATMENT OF TRUST UNIT LENDING AND SHORT SALES

The special rules of the Code that apply to securities lending  transactions do
not, by their terms, apply to interests in a partnership. Accordingly, a United
States holder whose Trust Units are loaned to a "short seller" to cover a short
sale of Trust Units may be considered as having  disposed of ownership of those
Trust Units. If so, it would no longer be a partner with respect to those Trust
Units  during  the period of the loan and may  recognize  gain or loss from the
disposition. As a result, during this period, any Trust income, gain, deduction
or loss with respect to those Trust Units would not be reportable by the United
States holder and any cash  distributions  received by the United States holder
with  respect to those Trust Units would be fully  taxable as ordinary  income.
United States holders  desiring to assure their status as owners of Trust Units
and avoid the risk of gain recognition  resulting from the application of these
rules should modify any  applicable  brokerage  account  agreements to prohibit
their brokers from borrowing or loaning their Trust Units.

The Code also contains  provisions  affecting the taxation of certain financial
products and securities,  including interests in entities such as the Trust, by
treating a taxpayer as having sold an "appreciated" interest, one in which gain
would be  recognized if it were sold,  assigned or otherwise  terminated at its
fair market value,  if the taxpayer or related persons enter into an offsetting
notional principal  contract,  or a futures or forward contract with respect to
the interest on substantially  identical property.  Moreover, if a taxpayer has
previously entered into a short sale, an offsetting notional principal contract
or a futures or forward  contract  with respect to the  interest,  the taxpayer
will be treated as having sold that portion if the taxpayer or a related person
then acquires the interest or substantially  identical property.  The Secretary
of Treasury  is  authorized  to issue  regulations  that treat a taxpayer  that
enters into  transactions or positions that have  substantially the same effect
as the  preceding  transactions  as having  constructively  sold the  financial
position.

DISPOSITION OF TRUST UNITS BY REDEMPTION

The tax  consequences  of a redemption of Trust Units are complex and depend in
part upon  whether  some or all of a United  States  holder's  Trust  Units are
redeemed.  The tax  consequences  of a  redemption  of all of a  United  States
holder's  Trust Units should  generally  be the same as  discussed  above under
"Disposition  of Trust  Units -  Recognition  of Gain or Loss."  United  States
holders  contemplating  a redemption of some or all of their Trust Units should
consult their tax advisors.


                                      28


UNIFORMITY OF TRUST UNITS

Because we cannot match  transferors  and  transferees of Trust Units,  we must
maintain  uniformity of the economic and tax characteristics of the Trust Units
to a purchaser of these Trust  Units.  In the absence of such  uniformity,  the
Trust may be unable to comply  completely  with a number of federal  income tax
requirements.

A lack of uniformity,  however,  can result from a literal  application of some
Treasury  regulations.  If any non-uniformity  was required by the Service,  it
could have a negative impact on the value of the Trust Units.

TAX-EXEMPT ORGANIZATIONS

Employee benefit plans (including  individual  retirement accounts ("IRAs") and
other retirement plans) and most other organizations exempt from federal income
tax (each,  a "TEO") are subject to federal  income tax on  unrelated  business
taxable  income  ("UBTI").  Because we expect  substantially  all income of the
Trust to be royalty income, rents from real property or interest, none of which
is UBTI,  a TEO should not be taxable on any income  generated  by ownership of
the Trust Units except as described in the next paragraph. However, the Royalty
Indenture is in several respects an unusual royalty indenture,  for which there
is no clear United  States  income tax  guidance.  It is possible  that the IRS
could contend that some or all of our income under the Royalty  Indenture  does
not  qualify  as royalty  income,  but  should  instead be treated as UBTI.  In
addition, the classification of certain facilities owned by us as real property
or  personal  property  is a  determination  subject  to  uncertainty.  If such
facilities  were  determined to be personal  property for United States federal
income  tax  purposes,  the  rent  derived  therefrom  would  be UBTI to a TEO.
Prospective  purchasers of Trust Units that are TEOs are  encouraged to consult
their tax advisors regarding the foregoing.

If the Trust  finances with  indebtedness  an acquisition of any property to be
held to produce  income,  income derived from such property in whole or in part
will  be  UBTI  to a TEO.  Furthermore,  if a TEO  acquires  Trust  Units  with
indebtedness,  then a portion of any  interest,  rents from real  property  and
royalty  income  received  by the TEO  attributable  to the Trust Units will be
treated as UBTI and thus will be taxable to a TEO.

ADMINISTRATIVE MATTERS

TRUST INFORMATION RETURNS

We are  currently  not  required  to file a United  States  federal  income tax
return,  since we have no gross income  derived from sources  within the United
States or gross income  which is  effectively  connected  with the conduct of a
trade or  business  within the United  States.  However,  the IRS may require a
United States holder to provide  statements or other information  necessary for
the IRS to verify the accuracy of the  reporting by the United States holder on
its income tax return of any items of our income,  gain,  loss,  deduction,  or
credit.  If we were to file a United States tax return in future tax years, the
filing  would  change  the manner in which we provide  tax  information  to the
United States  holders and special  procedures  would also apply to an audit of
such tax return by the IRS.


                                      29


REGISTRATION AS A TAX SHELTER

The Code requires that "tax  shelters" be registered  with the Secretary of the
Treasury.  The  temporary  Treasury  Regulations  interpreting  the tax shelter
registration  provisions of the Code are extremely  broad.  It is arguable that
the Trust is not subject to the  registration  requirement on the basis that it
will not constitute a tax shelter. However, we have registered as a tax shelter
with the Secretary of the Treasury  because of the absence of assurance that we
will not be subject to tax shelter registration and in light of the substantial
penalties which otherwise might be imposed if we failed to register and it were
subsequently  determined that registration was required. The IRS has issued the
Trust the following tax shelter registration number: 99068000003.

You  must  report  this  registration  number  to the  IRS,  if you  claim  any
deduction, loss, credit, or other tax benefit or report any income by reason of
your investment in the Trust. You must report the registration  number (as well
as the name, and taxpayer identification number of the Trust) on Form 8271. The
Trust's  taxpayer  identification  number  is  98-0185056.  Form  8271  must be
attached to the return on which you claim the deduction, loss, credit, or other
tax benefit or report any income of the Trust. A United States holder who fails
to  disclose  the  tax  shelter  registration  number  on his  return,  without
reasonable  cause for that failure,  will be subject to a $250 penalty for each
failure.

ISSUANCE OF A  REGISTRATION  NUMBER DOES NOT INDICATE THAT AN INVESTMENT IN THE
TRUST OR THE CLAIMED TAX BENEFITS HAVE BEEN REVIEWED,  EXAMINED, OR APPROVED BY
THE IRS.

A United  States  holder  who sells or  otherwise  transfers  Trust  Units must
furnish the tax shelter registration number to the transferee.  The penalty for
failure of the transferor of a Trust Unit to furnish the registration number to
the transferee is $100 for each such failure.

REPORTABLE TRANSACTIONS

Under  Treasury  Regulations,   certain  taxpayers  participating  directly  or
indirectly in a "reportable  transaction"  must disclose such  participation to
the IRS. The scope and  application of these rules is not completely  clear. An
investment  in the  Trust  may be  considered  participation  in a  "reportable
transaction" if, for example,  the Trust recognizes certain  significant losses
in the  future  and the  Trust  does  not  otherwise  meet  certain  applicable
exemptions.  If an  investment  in the  Trust  constitutes  participation  in a
"reportable  transaction,"  the  Trust and each  United  States  holder  may be
required to file IRS Form 8886 with the IRS,  including  attaching  it to their
United  States  federal  income  tax  returns,   thereby   disclosing   certain
information  relating  to the Trust to the IRS. In  addition,  the Trust may be
required to disclose Trust  reportable  transactions  and to maintain a list of
Unitholders  and to furnish this list and certain other  information to the IRS
upon its written request.  United States holders are urged to consult their own
tax advisors  regarding the applicability of these rules to their investment in
the Trust.

FOREIGN PARTNERSHIP REPORTING

A United States holder who contributes  more than US$100,000 to the Trust (when
added to the  value of any  other  property  contributed  to the  Trust by such
person or a related person during the previous 12 months) in exchange for Trust
Units, may be required to file Form 8865,  Return of United States Persons With


                                      30


Respect to Certain Foreign Partnerships, in the year of the contribution. There
may be other  circumstances in which a United States holder is required to file
Form 8865.

                DESCRIPTION OF THE TRUST UNITS TO BE REGISTERED

The  Trust  Units to be  offered  by this  prospectus  will be  offered  to our
Unitholders  pursuant  to  participation  in the  Plan.  The  Trust  Units  are
currently  listed on the TSX under the symbol  "PGF.UN"  and the NYSE under the
symbol "PGH".

Meetings of Unitholders  may be called on at least 21 and not more than 50 days
notice  and may be  called  at any time by the  Trust or by  Computershare,  as
trustee,  upon written request of Unitholders holding in the aggregate not less
than five percent of the aggregate number of Trust Units then  outstanding.  At
all  meetings of the  Unitholders  each  Unitholder  is entitled to one vote in
respect of each Trust Unit.  Unitholders may attend and vote at all meetings of
the  Unitholders  either in person or by proxy and a proxy holder need not be a
Unitholder.  Two persons  present in person and either  holding  personally  or
representing as proxies at least five percent of the aggregate  number of Trust
Units then  outstanding  constitute a quorum for the transaction of business at
all such meetings. Except as otherwise provided in the Trust Indenture, matters
requiring  the approval of the  Unitholders  must be approved by  extraordinary
resolution.

The Trust Units are  redeemable by  Computershare,  as trustee,  on demand by a
Unitholder,  when properly endorsed for transfer and when accompanied by a duly
completed and properly executed notice requesting  redemption,  at a redemption
price  equal to the lesser of: (i) 95 percent of the average  closing  price of
the Trust  Units on the  market  designated  by the board of  directors  of the
Corporation  for the ten  days  after  the  Trust  Units  are  surrendered  for
redemption; and (ii) the closing price of the Trust Units on such market on the
date the Trust Units are  surrendered  for  redemption.  The  redemption  right
permits  Unitholders to redeem Trust Units for maximum proceeds of Cdn. $25,000
in any  calendar  month  provided  that  such  limitation  may be waived at the
discretion of the board of the  Corporation.  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 natural gas  production,  which are held by the
Trust at the time the Trust  Units are to be  redeemed.  The price of the Trust
Units, as applicable, for redemption purposes is based upon the closing trading
price of the Trust Units.


                                      31


The  following  table sets forth the price  ranges of the Class A Units and the
Class B Units on the NYSE and the TSX through July 27, 2006,  being the date of
the  Consolidation,  and the price  range of the Trust Units on the TSX and the

be permitted to directors,  officers or persons  controlling the Trust pursuant
to the applicable  provisions of the Business Corporations Act (Alberta) or our
by-laws,  the  Trust  has been  informed  that in the  opinion  of the SEC such
indemnification is against public policy as expressed in the Securities Act and
is therefore unenforceable.

ITEM 8.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 124 of the Business Corporations Act (Alberta) provides as follows:

124(1)  Except in  respect of an action by or on behalf of the  corporation  or
body corporate to procure a judgment in its favour, a corporation may indemnify
a director or officer of the  corporation,  a former director or officer of the
corporation  or a person  who acts or acted at the  corporation's  request as a
director or officer of a body  corporate of which the  corporation  is or was a
shareholder  or  creditor,  and the  director's  or  officer's  heirs and legal
representatives,  against all costs, charges and expenses,  including an amount
paid to settle an action or  satisfy a  judgment,  reasonably  incurred  by the
director or officer in respect of any civil,  criminal or administrative action
or  proceeding  to which the  director  or officer is made a party by reason of
being  or  having  been a  director  or  officer  of that  corporation  or body
corporate, if

(a) the director or officer acted honestly and in good faith with a view to the
best interests of the corporation, and

(b) in the case of a criminal or  administrative  action or proceeding  that is
enforced by a monetary penalty,  the director or officer had reasonable grounds
for believing that the director's or officer's conduct was lawful.

(2) A  corporation  may with  the  approval  of the  Court  indemnify  a person
referred  to in  subsection  (1) in respect of an action by or on behalf of the
corporation or body corporate to procure a judgment in its favour, to which the
person  is made a party by  reason of being or  having  been a  director  or an
officer of the  corporation or body corporate,  against all costs,  charges and
expenses reasonably incurred by the person in connection with the action if the
person fulfills the conditions set out in subsection (1)(a) and (b).

(3)  Notwithstanding  anything  in  this  section,  a  person  referred  to  in
subsection (1) is entitled to indemnity from the  corporation in respect of all
costs,  charges and expenses  reasonably  incurred by the person in  connection
with the defence of any civil,  criminal or administrative action or proceeding
to which  the  person  is made a party by  reason  of  being or  having  been a
director or officer of the corporation or body corporate, if the person seeking
indemnity

(a) was  substantially  successful on the merits in the person's defence of the
action or proceeding,

(b) fulfills the conditions set out in subsection (1) (a) and (b), and

(c) is fairly and reasonably entitled to indemnity.

(3.1) A corporation may advance funds to a person in order to defray the costs,
charges and expenses of a proceeding  referred to in subsection (1) or (2), but
if the person does not meet the  conditions of  subsection  (3) he or she shall
repay the funds advanced.


                                      II-1


(4) A  corporation  may purchase and maintain  insurance for the benefit of any
person  referred to in  subsection  (1) against any  liability  incurred by the
person

(a) in the  person's  capacity  as a director  or  officer of the  corporation,
except when the liability  relates to the person's  failure to act honestly and
in good faith with a view to the best interests of the corporation, or

(b) in the person's capacity as a director or officer of another body corporate
if the person  acts or acted in that  capacity  at the  corporation's  request,
except when the liability  relates to the person's  failure to act honestly and
in good faith with a view to the best interests of the body corporate.

(5) A corporation  or a person  referred to in subsection  (1) may apply to the
Court for an order  approving an indemnity under this section and the Court may
so order and make any further order it thinks fit.

(6) On an application  under  subsection  (5), the Court may order notice to be
given to any  interested  person and that  person is  entitled to appear and be
heard in person or by counsel.

The by-laws of the Corporation and the Manager, respectively, provide that they
will  indemnify the  indemnified  persons  designated in Section  124(1) of the
Business  Corporations  Act  (Alberta)  of the  Corporation  and  the  Manager,
respectively,  in the manner  contemplated  by the  Business  Corporations  Act
(Alberta).

As contemplated by Section 124(4) of the Business  Corporations  Act (Alberta),
the Corporation has purchased  insurance  against  potential claims against the
directors  and  officers  of the  Corporation  and  against  loss for which the
Corporation may be required or permitted by law to indemnify such directors and
officers.

Pursuant to the Amended and  Restated  Management  Agreement  (the  "Management
Agreement")  dated  as of May  12,  2003  among  the  Corporation,  the  Trust,
Computershare  Trust  Corporation  of Canada and the  Manager,  the Manager and
these persons having served as a director, officer or employee thereof shall be
indemnified  by the  Corporation  (out of its  assets  and  out of the  royalty
provided for in the Amended and Restated Royalty Indenture dated as of July 27,
2006 between the Corporation and Computershare  Trust Corporation of Canada, as
trustee) for all liabilities and expenses arising from or in any matter related
to the Management Agreement,  so long as the party seeking such indemnification
shall not be adjudged liable for or guilty of willful  misfeasance,  bad faith,
gross negligence or reckless disregard of duty to the Corporation or the Trust,
and shall not be adjudged to be in breach of any material  covenants and duties
of the Manager under the Management Agreement.

Insofar as indemnification for liabilities arising under the Securities Act may
be permitted  to  directors,  officers or persons  controlling  the  Registrant
pursuant to the foregoing provisions,  the Registrant has been informed that in
the opinion of the Securities and Exchange  Commission such  indemnification is
against  public  policy as  expressed  in the  Securities  Act and is therefore
unenforceable.

Securities Act of 1933, each such  post-effective  amendment shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such  securities at that time shall be deemed to be the initial
bona fide offering thereof.

          (3)  To  remove  from  registration  by  means  of  a  post-effective

          (5)  That,  for  the  purpose  of  determining  liability  under  the
Securities Act of 1933 to any purchaser:

          (i) If the registrant is relying on Rule 430B:

          (A)  Each  prospectus  filed  by  the  registrant  pursuant  to  Rule
424(b)(3)  shall be deemed to be part of the  registration  statement as of the
date the filed  prospectus was deemed part of and included in the  registration
statement; and

          (B) Each prospectus  required to be filed pursuant to Rule 424(b)(2),
(b)(5), or (b)(7) as part of a registration  statement in reliance on Rule 430B

securities  in the offering  described in the  prospectus.  As provided in Rule
430B, for liability  purposes of the issuer and any person that is at that date
an  underwriter,  such date shall be deemed to be a new  effective  date of the
registration statement relating to the securities in the registration statement
to which that prospectus  relates,  and the offering of such securities at that
time shall be deemed to be the initial bona fide  offering  thereof.  PROVIDED,
HOWEVER, that no statement made in a registration  statement or prospectus that
is part of the  registration  statement or made in a document  incorporated  or
deemed incorporated by reference into the registration  statement or prospectus
that is part of the registration  statement will, as to a purchaser with a time
of  contract  of sale prior to such  effective  date,  supersede  or modify any
statement that was made in the  registration  statement or prospectus  that was
part of the  registration  statement or made in any such  document  immediately
prior to such effective date; or

          (ii) If the registrant is subject to Rule 430C, each prospectus filed
pursuant  to Rule  424(b) as part of a  registration  statement  relating to an
offering, other than registration statements relying on Rule 430B or other than
prospectuses  filed in reliance on Rule 430A, shall be deemed to be part of and
included in the  registration  statement  as of the date it is first used after
effectiveness.  PROVIDED,  HOWEVER,  that no statement  made in a  registration
statement or prospectus that is part of the registration statement or made in a
document incorporated or deemed incorporated by reference into the registration
statement or prospectus that is part of the registration  statement will, as to
a purchaser with a time of contract of sale prior to such first use,  supersede
or  modify  any  statement  that  was  made in the  registration  statement  or
prospectus  that was  part of the  registration  statement  or made in any such
document immediately prior to such date of first use.

          (6) That, for the purpose of determining  liability of the registrant
under the Securities  Act of 1933 to any purchaser in the initial  distribution
of the securities:

          The undersigned  registrant  undertakes that in a primary offering of
securities  of  the  undersigned   registrant  pursuant  to  this  registration
statement, regardless of the underwriting method used to sell the securities to


                                      II-5


the purchaser, if the securities are offered or sold to such purchaser by means
of any of the following  communications,  the undersigned  registrant will be a

the offering containing material  information about the undersigned  registrant
or its securities provided by or on behalf of the undersigned registrant; and

          (iv) Any other communication that is an offer in the offering made by
the undersigned registrant to the purchaser.

          (b) The undersigned  registrant  hereby undertakes that, for purposes
of determining  any liability  under the Securities Act of 1933, each filing of
the  registrant's  annual report  pursuant to section 13(a) or section 15(d) of
the Securities  Exchange Act of 1934 (and, where applicable,  each filing of an
employee  benefit  plan's  annual  report  pursuant  to  section  15(d)  of the
Securities  Exchange  Act of 1934) that is  incorporated  by  reference  in the
registration  statement  shall be  deemed  to be a new  registration  statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

                  (e) The undersigned registrant hereby undertakes to deliver
or cause to be delivered with the prospectus, to each person to whom the
prospectus is sent or given, the latest annual report to security holders that
is incorporated by reference in the prospectus and furnished pursuant to and
