                              4,000,000 Trust Units

                         DISTRIBUTION REINVESTMENT PLAN

      On February 18, 1998, we established a Distribution Reinvestment Plan (the
"Plan")  to  provide  holders  of our  trust  units  with a  means  to  reinvest
distributions  declared and payable to them as unitholders  in additional  trust
units of the  Trust.  The  Plan  was  subsequently  amended  on May 25,  2000 to
encourage greater participation by providing that reinvested distributions would
be  converted  to trust  units at a 5% discount  to the then  prevailing  market
price.  On  October  24,  2003 we  further  amended  the Plan to  provide  for a
"premium"  distribution  component of the Plan  pursuant to which holders of our
trust units could receive,  at their  election,  a cash payment equal to 102% of
the cash distribution  otherwise payable on such trust units. Finally, on August
29, 2005, we further  amended the Plan to provide,  among other things,  for the
participation of registered holders of trust units resident in the United States
in the distribution reinvestment component of 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
without paying any brokerage  commissions or service charges.  Our distributions
are paid on the 15th day of each  month,  or if such day is not a business  day,
the previous business day.

      The purchase price of trust units purchased on behalf of participants with
reinvested  distributions  on trust units is  calculated  based on the  weighted
average  trading price for all trust units traded on the Toronto Stock  Exchange
during the period ending on the second  business day  immediately  preceding the
applicable distribution date and beginning on the later of the 21st business day
prior to such distribution date and the second business day following the record
date for the  determination  as to the  unitholders  entitled  to  receive  such
distribution, less 5%. Our trust units trade on the Toronto Stock Exchange under
the symbol  "PWI.UN" and on the New York Stock  Exchange under the symbol "PWI".
The weighted  average of the high and low trading  prices for the trust units on
the Toronto  Stock  Exchange for the five days  preceding  September 7, 2005 was
Cdn.  $33.73.  The  closing  prices  for our trust  units on the  Toronto  Stock
Exchange  and on the New York  Stock  Exchange  on  September  7, 2005 were Cdn.
$33.74 and U.S. $28.42, 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, taxes, our direct expenses, reclamation fund contributions,  operating
costs,  debt  service  charges  and  general and  administrative  expenses.  See
"Special  Note  Regarding   Forward-Looking   Statements"  on  page  8  of  this
prospectus. See also "Risk Factors" in

our annual report on Form 40-F for the fiscal year ended December 31, 2004 filed
March 31, 2005.

      We cannot estimate  anticipated  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. $63,215.37 in connection with this offering and will
be  responsible  for  the  ongoing  administrative  costs  associated  with  the
operation of the Plan.

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

                The date of this prospectus is September 7, 2005.

                       WHERE YOU CAN FIND MORE INFORMATION

      We  are  subject  to the  informational  requirements  of  the  Securities
Exchange Act of 1934 (the "Exchange Act"),  and,  accordingly,  file reports and
other  information with the SEC. The reports and other  information we file with
the SEC in  accordance  with the Exchange Act can be  inspected  and copied,  at
prescribed  rates, at the SEC's public  reference rooms in Washington,  D.C. and
Chicago,  Illinois.  You may obtain  information  on the  operation of the SEC's
public  reference  rooms by calling the SEC at  1-800-SEC-0330.  Our filings are
also  electronically  available from the SEC's Electronic Document Gathering and

      Any statement  contained in a document  incorporated  by reference  herein
shall be deemed to be modified or superseded for purposes of this  prospectus to
the extent  that a statement  contained  herein or therein or in any other later
filed document  which also is  incorporated  by reference  into this  prospectus
modifies or supersedes that statement.  Any such statement so modified shall not
be deemed, except as so modified,  to constitute a part of this prospectus.  Any
such  statement so  superseded  shall be deemed not to constitute a part of this
prospectus.

      Any person receiving a copy of this  prospectus,  including any beneficial

                   ENFORCEABILITY OF CERTAIN CIVIL LIABILITIES

      We are an open-end  investment  trust organized under the laws of Alberta,
Canada and our principal offices are located in Calgary,  Alberta,  Canada.  The
enforcement by investors of civil liabilities under the United States securities
laws may be affected adversely by the fact that we have been organized under the
laws of Canada, that all of the officers and directors of PrimeWest Energy Inc.,
our duly authorized  attorney,  are residents of Canada, that some or all of the
experts  named in this  prospectus  may be residents of Canada and that all or a
substantial  portion of their  assets and our assets are located  outside of the
United States.  As a result,  it may be difficult for United States investors to
effect  service of  process  within  the  United  States  upon us and upon those
directors,  officers or experts who are not residents of the United States or to
realize in the United  States  upon  judgments  of courts of the United  States,
predicated  upon civil  liability of such persons  under United  States  federal
securities law or the securities law of any state of the United States. There is
doubt as to the  enforceability  in Canada  against us or against our directors,
officers  or experts who are not  residents  of the United  States,  in original
actions or in actions for  enforcement  of judgments of United  States courts of
liabilities based solely upon the United States

                                      - 7 -



federal  securities  laws or the securities  laws of any state within the United
States. We have appointed CT Corporation System, 111 - 8th Avenue, New York, New
York,  10011,  as our agent in the United  States upon which  service of process
against us may be made in any action based on this prospectus.

                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

      Certain statements contained in this prospectus,  and in certain documents
incorporated  by  reference  into this  prospectus,  constitute  forward-looking
statements.  The use of any of the words "anticipate",  "continue",  "estimate",
"expect",  "forecast", "may", "will", "project",  "should", "believe", "outlook"
and similar expressions are intended to identify forward-looking  statements. In
addition,  statements  relating to  "reserves" or  "resources"  are deemed to be
forward-looking statements, as they involve implied assessment, based on certain
estimates and  assumptions,  that the  resources  and reserves  described can be
profitably  produced in the future.  These statements  involve known and unknown
risks,  uncertainties  and other factors that may cause actual results or events
to differ materially from those anticipated in our  forward-looking  statements.
We believe the expectations  reflected in those  forward-looking  statements are
reasonable.  However, we cannot assure you that these expectations will prove to
be correct.  You should not unduly rely on forward-looking  statements  included
in, or incorporated by reference into, this  prospectus.  These statements speak
only as of the  date of  this  prospectus  or as of the  date  specified  in the
documents incorporated by reference into this prospectus, as the case may be.

      In  particular,   this  prospectus,  and  the  documents  incorporated  by
reference, contain forward-looking statements pertaining to the following:

o     the quantity and recoverability of our reserves:

o     the timing and amount of future production;

o     prices for oil, natural gas and natural gas liquids produced;

o     operating and other costs;

o     business strategies and plans of management;

o     supply and demand for oil and natural gas;

o     expectations  regarding  our  ability to raise  capital  and to add to our
      reserves through acquisitions and exploration and development;

o     our treatment under governmental regulatory regimes;

o     the focus of capital  expenditures  on  development  activity  rather than
      exploration;

o     the sale,  farming in, farming out or  development of certain  exploration
      properties using third-party resources;

o     the   objective   to  achieve  a   predictable   level  of  monthly   cash
      distributions;

o     the use of  development  activity and  acquisitions  to replace and add to
      reserves;

o     the  impact of changes  in oil and  natural  gas prices on cash flow after
      hedging;

                                      - 8 -



o     drilling plans;

o     the  existence,  operations  and  strategy  of the  commodity  price  risk
      management program;

o     the  approximate  and  maximum  amount of forward  sales and hedging to be
      employed;

o     our  acquisition  strategy,  the criteria to be  considered  in connection
      therewith and the benefits to be derived therefrom;

o     the impact of the Canadian federal and provincial  governmental regulation
      on us relative to other oil and natural gas issuers of similar size;

o     the goal to sustain or grow production and reserves through prudent
      management and acquisitions;

o     the  emergence of  accretive  growth  opportunities;  and

o     our ability to benefit from the  combination of growth  opportunities  and
      the ability to grow through the capital markets.

      Our actual results could differ materially from those anticipated in these
forward-looking  statements  as a result of the risk factors set forth below and
incorporated by reference into this prospectus:

o     volatility in market prices for oil and natural gas;

o     the impact of weather conditions on seasonal demand;

o     risks inherent in our oil and natural gas operations;

o     uncertainties associated with estimating reserves;

o     competition  for, among other things:  capital,  acquisitions of reserves,
      undeveloped lands and skilled personnel;

o     incorrect assessments of the value of acquisitions;

o     geological, technical, drilling and processing problems;

o     general economic conditions in Canada, the United States and globally;

o     industry  conditions,  including  fluctuations  in the  price  of oil  and
      natural gas;

o     royalties payable in respect of our oil and natural gas production;

o     government  regulation  of the oil and  natural  gas  industry,  including
      environmental regulation;

o     fluctuation in foreign exchange or interest rates;

o     unanticipated  operating  events  that  can  reduce  production  or  cause
      production to be shut-in or delayed;

o     failure to obtain  industry  partner and other  third-party  consents  and
      approvals, when required;

o     stock market volatility and market valuations;

o     OPEC's ability to control  production and balance global supply and demand
      of crude oil at desired price levels;

o     political  uncertainty,   including  the  risks  of  hostilities,  in  the
      petroleum producing regions of the world;

                                      - 9 -



o     the need to obtain required approvals from regulatory authorities; and

o     the other factors  discussed under  "Operational and Other Business Risks"
      contained  in our  Annual  Report on Form 40-F for the  fiscal  year ended
      December 31, 2004 incorporated herein by reference.

      These factors should not be construed as exhaustive.  The  forward-looking
statements  contained  in this  prospectus  and the  documents  incorporated  by
reference  herein are  expressly  qualified  by this  cautionary  statement.  We
undertake  no  obligation  to  publicly  update  or revise  any  forward-looking
statements.

                                    THE TRUST

      We are a  Canadian  based  energy  business  engaged  in the  acquisition,
development,  exploitation  and production of oil and natural gas properties and
the marketing and sale of oil and natural gas. Our trust units are listed on the
Toronto  Stock  Exchange  and  the  New  York  Stock  Exchange  and  our  market
capitalization as at September 7, 2005 was approximately Cdn. $2.6 billion.  Our
operations are currently focused  exclusively on western Canada. We have been in
operation  since  October  1996 and are  governed by the laws of the Province of
Alberta.

      Our  primary   purpose  is  to  generate  and  distribute  cash  flows  to
unitholders at minimal risk and we therefore pursue an acquisition  strategy and
development  program  focused  on oil  and  natural  gas  properties.  We do not
participate in exploration  activity because of the higher risks associated with
exploration.  As a result,  our  production is typically  more  predictable  and
stable than traditional  exploration and production companies and our operations
not as capital intensive.

      We make monthly  distributions  to our unitholders from the net cash flows
that we receive from our oil and natural gas operations.  The amount of that net
cash flow is subject to many factors,  including fluctuations in the quantity of
oil and natural gas that we produce,  the prices we receive for that production,
hedging contract receipts and payments, taxes, our direct expenses,  reclamation
fund  contributions,  operating  costs,  debt  service  charges  and general and
administrative  expenses.  Our monthly  distributions  currently comprise both a
return on capital and a return of capital.

                                 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
sold.  The amount of the proceeds that we will 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 Canadian  participants  in  additional  trust units
through  the  optional  trust unit  purchase  aspect of the Plan (see "The Plan"
below). We do not expect the amount

                                     - 10 -



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 our Plan is to provide  holders of our trust  units with a
means to receive either, but not both, of the following  benefits:  (i) reinvest
distributions  declared and payable to them as unitholders  in additional  trust
units of the Trust without paying any brokerage  commissions or service  charges
and at a 5% discount to the average market price;  or (ii) realize an additional
2% on their monthly cash distribution. Of these, only the reinvestment option is
available to residents of the United States.

      In addition,  regardless of which option a unitholder  that is resident in
Canada selects,  the Distribution  Reinvestment  Plan provides such participants
with the opportunity to purchase  additional trust units at a 5% discount to the
average  market  price,  up  to  an  annual  maximum  of  Cdn.   $100,000.   Our
distributions  are paid on the 15th day of each  month,  or if such day is not a
business day, the previous  business day, to  unitholders  of record on the last
day of the immediately preceding calendar month.

      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,   taxes,   our  direct   expenses,   reclamation   fund
contributions,   operating   costs,   debt  service   charges  and  general  and
administrative  expenses.  Our policy in respect of  distributions  is  reviewed
periodically in order to establish  distribution  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 holder  of at
least one trust  unit,  resident  in Canada or the  United  States  and meet the
requirements outlined below. The extent to which you may directly participate in
the Plan will depend on the manner in which you hold your trust units.

      If you are a registered  owner you may directly  enrol in the Plan. If you
are a beneficial  owner then, in order to participate in the Plan, you must make
arrangements through your broker,  investment dealer,  financial  institution or
other nominee who holds the trust units on your behalf.

      To become a participant, you or your nominee must complete a participation
form  authorizing us to forward all cash  distributions  paid on all trust units
registered in

                                     - 11 -



your name or in your  nominee's  name on your behalf,  now or in the future,  to
Computershare  Trust  Company of Canada,  the plan agent for the Plan (the "Plan
Agent"). The completed  participation form should be forwarded to the Plan Agent
at the address set out under "Notices"  below.  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.  The optional cash payment component and premium
distribution component of the Plan are available only to Canadian residents.

      If you are a  beneficial  owner  and wish to  participate  in  either  the
premium distribution component or the distribution reinvestment component of the
Plan, then you must determine  whether your nominee allows  participation in the
Plan.  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.  If you wish to participate and your nominee does allow it,
you must arrange for your  nominee to enroll in either the premium  distribution
component or the distribution reinvestment component of the Plan on your behalf.
If you choose to enroll in the Plan,  your  nominee will be required to elect to
participate on your behalf every distribution period.

      If the trust units are  registered in more than one name,  all  registered
holders must sign the participation form. In addition,  if your total holding is
registered in different names (eg. 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 unitholdings  are to be reinvested under one account,  the registration
names must be identical.

      You may  obtain a  participation  form at any time by either  providing  a
written   request   to  the  Plan   Agent  or  by   visiting   our   website  at
www.primewestenergy.com.  If you are a registered holder, once you have enrolled
in the Plan, you will remain  enrolled until you  discontinue  participation  or
until we terminate the Plan. If you are a beneficial  holder,  your nominee will
be required to elect to  participate on your behalf every  distribution  period.
See "Amendments, Suspension or Termination of Plan and Plan Agent" below.

      Your participation in the Plan will commence with the distribution payment
date  following  the  month  in  which  you  or  your  nominee   submitted  your
participation form, provided that:

                                     - 12 -



(i)   if you are a registered  owner of trust units, the Plan Agent received the
      form no later than 4:00 p.m.  (E.S.T.)  on the  business  day  immediately
      preceding the distribution record date to which such distribution relates;

(ii)  if you are a  beneficial  owner of trust  units  resident  in Canada,  The
      Canadian  Depository for Securities Limited ("CDS") received the form from
      your nominee no later than 4:00 p.m.  (E.S.T.) on the second  business day
      immediately   preceding  the  distribution   record  date  to  which  such
      distribution relates; or

(iii) if you are a  beneficial  owner  of trust  units  resident  in the  United
      States,  The Depository  Trust Company ("DTC") received the form from your
      nominee no later than 4:00 p.m.  (E.S.T.) on the business day  immediately
      following the distribution record date to which such distribution relates.

      If the  participation  form is not received by the Plan Agent, CDS or DTC,
as  applicable,  prior to 4:00 p.m.  (E.S.T.)  on the  applicable  business  day
preceding or following the distribution record date, as the case may be, date to
which such  distribution  relates,  the distribution  will be paid to you in the
usual  manner  and  participation  in the  Plan  will  commence  with  the  next
distribution.

      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.

      You may not  transfer  the  right to  participate  in the Plan to  another
person.

      Death will not affect your election to participate unless a written notice
of death of a  participant  is provided to the Plan Agent.  Written  notice of a
participant's death must be received prior to 4:00 p.m. (E.S.T.) on the business
day  immediately  preceding a  distribution  record date to be effective for the
distribution  payment date to which it relates.  Otherwise,  such written notice
will be effective for the  distribution  payment date following the distribution
payment date to which such distribution record date relates.

Optional Trust Unit Purchases Pursuant to the Plan

      Additionally,  residents  of Canada are eligible to make  additional  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  who are  resident  in  Canada  may  invest a  minimum  of $100 per
optional  cash payment to a maximum of $100,000 per calendar  year. No more than
2% in aggregate of the number (at the  commencement  of that  calendar  year) of
outstanding  trust  units  may be  purchased  by all  participants  pursuant  to
optional cash payments in any calendar year.

                                     - 13 -



      The  optional  cash payment  component  of the Plan is  available  only to
Canadian residents.

Premium Distribution

      Where  participants  elect to receive the premium  distribution,  the Plan
Agent will pre-sell, through a qualified investment dealer designated by us from
time to time to act as plan broker under the Plan (the "Plan Broker"), in one or
more  transactions  in the  Canadian  market,  that  number of trust units to be
purchased on the distribution payment date with the reinvested  distributions of
such  participants.  The Plan Agent will receive  from the Plan Broker,  for the
account of such participants, subject to proration in certain circumstances, the
premium  distribution in an amount equal to 102% of the distributions  that such
participants  would have otherwise been entitled to receive on that distribution
payment  date.  On the  distribution  payment  date the trust  units  that would
otherwise  have  been  issued to the  participant  will be issued at the same 5%
discount to the  average  market  price to the Plan  Broker.  If the  prevailing
market  prices  realized  by the Plan Broker are  approximately  the same as the
average market price,  then the difference  between the issue price of the trust
units and the price realized on the pre-sales will be approximately  5%. Of this
difference,  2% will be paid to the  participant  (resulting in the 102% premium
distribution)  and the balance (which may be more or less than 3%), if any, will
be retained by the Plan Broker as  compensation  for its services in  connection
with the Plan.

      The  premium  distribution  component  of the  Plan is  available  only to
Canadian residents.

Method of Purchase

      Under the terms of the Plan,  if you are a holder of trust units,  you may
direct  the  Plan  Agent  to  reinvest  all cash  distributions  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  payment  date to the
purchase of trust units for that  participant.  The Plan Agent will, in the case
of a resident of Canada and depending on the participant's election,  either (i)
exchange the additional trust units for the premium distribution,  which will be
sent to the participant or its nominee  ordinarily at such time as distributions
are paid to unitholders  following a  distribution  payment date, or (ii) credit
the  additional  trust  units to the  participant's  or its  nominee's  account.
Residents of the United  States who are  participants  are only entitled to have
the  additional  trust units  credited to their,  or their  resident  nominee's,
account. To the extent proration becomes necessary in certain circumstances, the
trust units  purchased  from the Trust will be  allocated on a pro rata basis to
participants (i) first, to participants electing to

                                     - 14 -



reinvest distributions under the distribution reinvestment component of the Plan
and (ii) second, from participants electing to receive the premium distribution.

Purchase Price

      The Plan Agent  shall  purchase  trust  units from the Trust at a purchase
price per trust unit equal to the weighted  average  trading  price of all trust
units  traded on the  Toronto  Stock  Exchange  during the period  ending on the
second business day immediately  preceding the applicable  distribution date and
beginning on the later of the 21st business day prior to such  distribution date
and the second business day following the record date for the  determination  as
to the unitholders entitled to receive such distribution, 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 a 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

      Computershare Trust Company of Canada, as Plan Agent for the participants,
will administer the Plan. Its responsibilities include:

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

o     setting  up an  account  for each  participant  as a  sub-account  of, but
      directly linked with, each  participant's  registered  account outside the
      Plan;

o     receiving eligible funds;

o     purchasing  and  crediting the trust units  accumulated  under the Plan to
      each participant's account;

o     reporting monthly to the participants; and

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

Participants' Accounts and Reports

      The Plan Agent will maintain a separate account for each participant which
will be credited with the trust units  allocated to such  participant or, if the
participant  has elected to receive the premium  distribution,  mail the premium
distribution  to such  participant.  The Plan Agent  will,  on a monthly  basis,
furnish  to  each  participant  not  electing  to  participate  in  the  premium
distribution  component of the Plan, a report of the trust units  purchased  for
such participant (including, in the case of Canadian residents only, trust units
purchased  pursuant to optional cash  payments) in respect of

                                     - 15 -



each distribution  made in the most recently  completed month and the cumulative
total of all trust units purchased for that account. If you elect to receive the
premium distribution, then you will not receive a statement of account, as those
trust units purchased with your reinvested  distributions  are exchanged for the
premium distribution cash payment.

      These reports will be the only record for participants of the cost of each
purchase of trust units. All such reports should be retained by participants for
income tax purposes.  In addition,  each  participant  will receive annually the
appropriate tax information for recording  distribution income. The reinvestment
of distributions under the Plan will not relieve  participants of any income tax
applicable to such distributions.

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 request  that a  certificate  for the required  number of trust units be
issued before such action may be taken.  Certificates  will be issued as soon as
practicable  and  generally  within  two weeks of receipt by the Plan Agent of a
participant's  written request.  Both the new  certificated  trust units and the
trust units remaining in a participant's account will continue to receive either
the premium  distribution  or additional  units pursuant to the  reinvestment of
distributions as was elected by such unitholder.

Commissions and Administrative Costs

      There will be no commissions, service charges or brokerage charges payable
by participants in connection with the purchase of additional  trust units under
the  Plan.  Administrative  costs  associated  with the  operation  of the Plan,
including the fees and expenses of the Plan Agent, will be borne by us. The Plan
Agent will be paid fees for its services  pursuant to a reinvestment plan agency
agreement  between us and the Plan

                                     - 16 -



Agent and the Plan Broker  will be paid in the manner set forth  under  "Premium
Distribution" above pursuant to a premium distribution agency agreement.

Responsibilities of the Trust, PrimeWest Energy Inc. and the Plan Agent

      Neither  we 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 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  by,  in the  case  of  registered
unitholders,  providing  written  termination  notice to the Plan Agent no later
than  4:00  p.m.  (E.S.T.)  on  the  business  day  immediately   preceding  the
distribution  record date for the next distribution.  If the termination form is
not  received by the Plan Agent prior to 4:00 p.m.  (E.S.T.) on the business day
immediately  preceding the distribution  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.  In the case of
beneficial  holders,  as participation  must be renewed on a monthly basis, your
participation  may  be  terminated  simply  by  your  nominee  not  electing  to
participate in the Plan on your behalf for a particular distribution.

      Upon termination of participation in the Plan, the Plan Agent will as soon
as  practicable   (and  in  any  event  within  20  business  days)  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 may amend,  suspend or terminate the Plan at any time,  but such
action shall have no  retroactive  effect that would  prejudice the interests of
participants.  Where  required,  amendments  to the Plan will be  subject to the
prior approval of the Toronto Stock Exchange.  The Trust will notify unitholders
of any amendment,  suspension or termination of the Plan in accordance  with the
Plan and any applicable securities law requirements.

                                     - 17 -



      The Trust,  may, in its sole  discretion,  and upon 90 days' notice to the
Plan Agent, remove the Plan Agent and appoint any other person licensed to carry
on the business of a trustee in Alberta, Canada as the Plan Agent.

      Similarly, the Plan Agent may resign as agent under the Plan upon 90 days'
notice to the Trust and upon  delivery to the Trust of all  documents and monies
being held by the Plan Agent on the Trust's behalf pursuant to the Plan.

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

the Province of Alberta and the laws of Canada applicable therein.

                 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

                                     - 18 -



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  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 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 that  legislative,  judicial  or  administrative  changes  will not modify or
change the statements  expressed  herein after the date of the Plan.

      Generally,  that  portion  of the  distributions  paid by the  Trust  to a
Non-Resident  unitholder  that  constitutes  a portion  of the net income of the
Trust for a taxation  year that is paid or becomes  payable to the  Non-Resident
unitholder in that particular  taxation year is subject to Canadian  withholding
tax under the Tax Act at a rate of 25%, subject to reduction under an applicable
bilateral tax treaty. In the case of a Non-Resident unitholder who is a resident
of the United States for the purposes of the Canada-U.S. Tax Treaty, the rate of
such withholding tax is generally reduced to 15%.

      All other distributions paid by the Trust to a Non-Resident unitholder are
subject  to a special  Canadian  withholding  tax under the Tax Act at a rate of
15%. This rate  generally is not reduced  under any of Canada's tax treaties.  A
Non-Resident  unitholder  who  disposes of trust units (or units of other mutual
fund trusts similar to the Trust) at a loss  (calculated in Canadian dollars and
pursuant  to the rules in the Tax Act) may be entitled to obtain a refund of all
or a portion of any such withholding tax paid.

      It is not certain,  under the Proposed  Amendments,  whether the amount by
which  the fair  market  value of the trust  units  received  by a  Non-Resident
unitholder on a

                                     - 19 -



reinvestment  of cash  distributions  pursuant to the Plan exceeds the amount of
the cash  reinvested  (that is,  the 5%  discount)  is  subject  to this new 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.

      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  PrimeWest  Energy  Inc.  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 our trust
units to a  unitholder  who is a United  States  person  and who holds our trust
units as capital  assets  (referred to as a "United  States  unitholder").  This
description is for general information  purposes only and is based on the United
States  Internal  Revenue Code of 1986, as amended  (referred to as the "Code"),
Treasury regulations promulgated under the Code, and judicial and administrative
interpretations of the Code and those regulations,  all as in effect on the date
of this  prospectus  and all of which  are  subject  to  change,  possibly  with
retroactive  effect.  The tax treatment of a United States  unitholder  may vary
depending upon his particular  situation.  Some holders  (including persons that
are  not  United  States  persons,   banks,   insurance  companies,   tax-exempt
organizations,  financial institutions, persons whose functional currency is not
the  U.S.

                                     - 20 -



dollar,  persons subject to the alternative  minimum tax and broker-dealers) may
be subject to special rules not discussed  below.  The discussion below does not
address  the effect of any state,  local or foreign  tax law on a United  States
unitholder.  There can be no assurance that the United States  Internal  Revenue
Service (the "IRS") will take a similar  view as to any of the tax  consequences
described in this summary.  Purchasers of our trust units are advised to consult
their own tax advisors with respect to an investment in our trust units.

      For purposes of this  description,  a "United States person" means any one
of the following:

o     an individual who is a citizen or resident of the United States;

o     a corporation  (including  any entity  treated as a  corporation  for U.S.
      federal income tax purposes)  organized in or under the laws of the United
      States or of any political subdivision of the United States;

o     an estate that is subject to United States federal income taxation without
      regard to the source of its income; or

o     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 the trust has made a
      valid election to be treated as a United States person.

      If a partnership  (including  any entity treated as a partnership or other
pass through  entity for United States  federal income tax purposes) is a holder
of trust units,  the United States  federal income tax treatment of a partner in
the  partnership  generally  will  depend on the status of the  partner  and the
activities of the partnership.  Partners and  partnerships  should consult their
tax advisors as to the particular federal income tax consequences  applicable to
them.

Our Classification as a Foreign Corporation

      Although we are organized as an unincorporated  open-end  investment trust
under Canadian law, we are classified as a foreign corporation for United States
federal income tax purposes under current Treasury regulations. Accordingly, our
trust  units  will be treated  as shares of stock of a foreign  corporation  for
United  States  federal  tax  purposes.   The  discussion  below  reflects  this
classification  and employs  terminology  consistent  with this  classification,
including references to "dividends" and "earnings and profits".

Amount Capable of Inclusion in Income

      For United States federal income tax purposes,  a United States unitholder
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  payment
date of trust units  acquired

                                     - 21 -



pursuant to the Plan, and (ii) any Canadian taxes which we withhold with respect
to the  distribution.  The amount treated as a  distribution  will be capable of
inclusion in the United States  unitholder's income as a taxable dividend to the
extent  of  the  Trust's  current  and  accumulated  earnings  and  profits,  as
determined for United States federal income tax purposes.  These  dividends will
not be eligible for the dividends received deduction, which is generally allowed
to United States  corporate  shareholders on dividends  received from a domestic
corporation.  Any portion of the  distribution in excess of the Trust's earnings
and profits will first be treated as a tax-free  return of capital to the extent
of the  United  States  unitholder's  tax basis in its  trust  units and will be
applied  against and reduce  that basis on a  dollar-for-dollar  basis  (thereby
increasing the amount of gain and decreasing the amount of loss  recognized on a
subsequent  disposition  of the  units).  To the  extent  that the  distribution
exceeds the United States  unitholder's  tax basis,  the excess will  constitute
gain from a sale or  exchange  of the trust  units.  If,  however,  the  passive
foreign  investment  company  rules  apply and any  portion of the  distribution
constitutes an "excess  distribution" to a United States unitholder that has not
made a "QEF election" (both terms as defined below),  then that portion would be
subject to tax under other, less favourable rules (discussed below).

      A United States unitholder will generally  recognize gain or loss upon the
sale or exchange of our trust units equal to the difference (if any) between the
amount the  unitholder  realizes on the sale or exchange  and its  adjusted  tax
basis in our trust units. Any gain or loss will be capital gain or loss and will
be long-term  capital  gain or loss if the United  States  unitholder's  holding
period for the units is more than one year at the time of the sale or exchange.

      Foreign Currency Gains

      Taxable  dividends  with  respect  to our  trust  units  that  are paid in
Canadian  dollars  will be  included  in the  gross  income  of a United  States
unitholder  as  translated  into U.S.  dollars  calculated  by  reference to the
exchange  rate in effect on the day the  dividend is received by the  unitholder
regardless of whether the Canadian  dollars are converted  into U.S.  dollars at
that time. A United States unitholder who receives a payment in Canadian dollars
and converts  Canadian dollars into U.S. dollars at a conversion rate other than
the rate in effect on the day of the  distribution  may have a foreign  currency
exchange  gain or loss that would be treated as United  States  source  ordinary
income or loss.  United  States  unitholders  are urged to consult their own tax
advisors concerning the United States tax consequences of acquiring, holding and
disposing of Canadian dollars.

      In the case of a cash basis United States unitholder who receives Canadian
dollars,  or another foreign  currency,  in connection with a sale,  exchange or
other  disposition of our trust units,  the amount realized will be based on the
U.S. dollar value of the foreign currency  received with respect to the units as
determined  on the  settlement  date of the sale or exchange.  An accrual  basis
United States  unitholder  may

                                     - 22 -



elect the same treatment required of cash basis taxpayers with respect to a sale
or exchange of trust units,  provided that the election is applied  consistently
from year to year.  This election may not be changed  without the consent of the
IRS. If an accrual basis United States  unitholder  does not elect to be treated
as a cash basis  taxpayer,  that  United  States  unitholder  may have a foreign
currency gain or loss for United States federal  income tax purposes  because of
differences between the U.S. dollar value of the currency received prevailing on
the date of the sale or  exchange  of the trust  units and the date of  payment.
This currency gain or loss would be treated as ordinary income or loss and would
be in  addition  to gain or  loss,  if any,  recognized  by that  United  States
unitholder on the sale, exchange or other disposition of the units.

      Basis and Holding Period

      The tax  basis of trust  units  received  by a  United  States  unitholder
pursuant  to the Plan will equal the fair  market  value as of the  distribution
payment date of those units,  and the holding  period for those units will begin
on the day after the distribution payment date.

Passive Foreign Investment Company Status

      As stated above,  the United States  federal  income tax  consequences  of
participation  in the Plan for a  United  States  unitholder  will  depend  to a
significant  extent on whether the Trust is a passive foreign investment company
at any time during the  participating  unitholder's  holding period of our trust
units.

      For United States  federal income tax purposes,  a foreign  corporation is
classified  as a passive  foreign  investment  company for each  taxable year in
which either:

o     at least 75% of its gross income is "passive"  income  (referred to as the
      "income test"); or

o     at least 50% of the average value of its assets is  attributable to assets
      that  produce  passive  income or are held for the  production  of passive
      income (referred to as the "asset test").

      For  purposes  of the  income  test  and  the  asset  test,  if a  foreign
corporation  owns directly or indirectly at least 25% (by value) of the stock of
another corporation,  that foreign corporation will be treated as if it held its
proportionate share of the assets of the other corporation and received directly
its  proportionate  share of the income of that  other  corporation.  Also,  for
purposes of the income test and the asset test,  passive income does not include
any income that is interest, a dividend or a rent or royalty,  which is received
or accrued from a related person to the extent that amount is properly allocable
to the  income of the  related  person  that is not  passive  income.  For these
purposes,  a person is "related"  with respect to a foreign  corporation if that
person  controls  the  foreign  corporation  or is  controlled  by  the  foreign
corporation  or by the

                                     - 23 -



same persons that control the foreign corporation. For these purposes, "control"
means  ownership,  directly or indirectly,  of stock possessing more than 50% of
the total voting power of all classes of stock  entitled to vote or of the total
value of stock of a corporation.

      Passive  income  also  includes  the excess of gains over losses from some
commodities  transactions,  including some  transactions  involving oil and gas.
Under  recently  amended  rules  (first  effective  for  2005)  net  gains  from
commodities  transactions  will not be  included  in the  definition  of passive
income if they are active business gains or losses from the sale of commodities.
However,   this  exception  will  only  apply  if   substantially   all  of  the
corporation's  commodities  are stock in trade or inventory of the  corporation,
property used in the trade or business of the  corporation,  or supplies used in
the ordinary course of a trade or business of the corporation.

      Both under these rules and  definitions,  and under  rules  applicable  in
2004,  we believe that:  (i) neither the Trust nor  PrimeWest  Energy Inc. was a
passive foreign  investment  company in 2004; and (ii) under the new rules, none
of the Trust,  nor its  subsidiaries,  PrimeWest  Energy Inc. and  PrimeWest Gas
Corp.  (collectively,  the "PrimeWest  Subsidiaries")  will be a passive foreign
investment company in 2005 or subsequent years. It is, however,  likely that the
Trust and/or PrimeWest Energy Inc. were passive foreign investment companies for
taxable years before 2002. We note,  however,  that passive  foreign  investment
company  status  is  fundamentally  factual  in  nature,   generally  cannot  be
determined  until the close of the taxable  year in question  and is  determined
annually.  Consequently,  we can  provide  no  assurance  that we will  not be a
passive  foreign  investment  company for either the current taxable year or for
any  subsequent  taxable year.  United States  unitholders  are urged to consult
their  own tax  advisors  regarding  our  possible  classification  as a passive
foreign investment company and the consequences if that  classification  were to
occur.

      If a United States  unitholder  participates in the Plan and the Trust was
not a passive  foreign  investment  company at any time during the  unitholder's
holding  period of our  trust  units,  the  United  States  federal  income  tax
consequences to the unitholder will generally be as described above. See "Amount
Capable of Inclusion in Income".

Tax  Consequences  if We Are or Have Been a Passive Foreign  Investment  Company
During Your Holding Period

      If the Trust is classified as a passive foreign  investment  company,  for
any year during which a United  States  unitholder  has held our trust units and
that  unitholder  has  not  made  a  qualified   electing  fund  election  or  a
mark-to-market   election  (both  as  described  below),  that  unitholder  will
generally be subject to special rules, regardless of whether the Trust continues
to be a  passive  foreign  investment  company,  with  respect  to  any  "excess
distribution"  (as defined  below) and any gain  realized upon the sale or other
disposition of our trust units.  Thus,  these rules may apply to a United States

                                     - 24 -



unitholder  whose holding  period with respect to our trust units began prior to
2002 even if the Trust  otherwise is not a passive  foreign  investment  company
thereafter. Under these rules:

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

o     the amount allocated to the current taxable year and any year prior to the
      first year in which we are a passive  foreign  investment  company will be
      taxed as ordinary income in the current year;

o     the amount allocated to each of the other taxable years 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 of the other taxable
      years.

      An "excess  distribution",  in general,  is any  distribution on our trust
units received in a taxable year by a United States  unitholder  that is greater
than 125% of the average annual distributions received by that unitholder in the
three preceding taxable years or, if shorter,  that unitholder's  holding period
for  our  trust  units.  A  distribution  will  not  be  treated  as  an  excess
distribution  for the taxable  year during  which a United  States  unitholder's
holding  period for our trust units  begins.  A United  States  unitholder  that
participates  in the Plan  will  generally  be  treated  as  having  received  a
distribution,  and some part or all of the distribution may constitute an excess
distribution. Any portion of the distribution deemed received by that unitholder
which does not constitute an excess distribution will be taxable under the rules
described above in "Amount Capable of Inclusion in Income."

      A United States person who holds  "marketable  stock" of a passive foreign
investment  company may avoid the  imposition of the additional tax and interest
rules described above by making a "mark-to-market" election in the first year of
his holding period with respect to the passive foreign investment company stock.
Our trust units should be treated as  "marketable  stock" for purposes of making
that  election.  If a United  States  unitholder  makes a timely  mark-to-market
election  with  respect  to our  trust  units  that it owns at the  close of its
taxable year, the United States  unitholder  would include as ordinary income in
that  taxable  year any excess of the fair  market  value of the  United  States
unitholder's trust units as of the close of such year over its adjusted basis in
the units. Any mark-to-market loss is treated as an ordinary deduction, but only
to the extent of prior ordinary  income included  pursuant to the election.  The
electing United States  unitholder's  basis in our trust units would be adjusted
to reflect any such income or loss amounts.  Any gain or loss on the sale of our
trust units would be  ordinary  income or loss,  except that any loss will be an
ordinary loss only to the extent of the previously  included net  mark-to-market
gain. An election to  mark-to-market  applies to the year for which the election
is made and the following

                                     - 25 -



years  unless  the  passive  foreign  investment  company  stock  ceases  to  be
marketable or the IRS consents to the revocation of the election.

      The  mark-to-market  rules do not appear to prevent the application of the
excess  distribution rules in respect of stock of the PrimeWest  Subsidiaries in
the event that either or both  corporations  were  considered a passive  foreign
investment  company.  For  purposes of the passive  foreign  investment  company
rules,  if the Trust were classified as a passive  foreign  investment  company,
United  States  unitholders  would be deemed to own an  interest  in any passive
foreign investment company that is treated as being owned directly or indirectly
by the Trust. Thus, if the Trust were classified as a passive foreign investment
company  and  either  or  both  of  the  PrimeWest  Subsidiaries  were  also  so
classified,  United States unitholders would be deemed to own an interest in any
PrimeWest  Subsidiary  that was so classified.  Accordingly,  if the Trust and a
PrimeWest Subsidiary were considered passive foreign investment companies, and a
United  States  unitholder  made a  mark-to-market  election with respect to the
Trust,   the  United  States   unitholder  may  remain  subject  to  the  excess
distribution  rules  described  above  with  respect  to  its  indirectly  owned
PrimeWest  Subsidiary  stock. If a timely "QEF election" (as defined below) were
made by a United States unitholder,  the rules described in this paragraph would
not apply.

      Alternatively,  if a United States  unitholder  were able to make a timely
qualified electing fund election (referred to as a "QEF election"),  that holder
would be able to avoid the additional tax and interest rules described above and
instead would be required to include in income each year such holder's  share of
the Trust's net ordinary income and capital gains, if any.  Generally,  in order
to avoid taxation under the excess  distribution rules, the QEF election must be
made in a timely filed federal  income tax return of a United States  unitholder
for the first  taxable  year of the United  States  unitholder  during which the
Trust was (at any time) a passive  foreign  investment  company.  A QEF election
cannot,  however,  be validly  made unless the Trust  agrees to provide  certain
United States tax basis  information  and meet certain other  requirements.  The
Trust has not yet  determined  whether it will provide that  information or meet
those  requirements.  Therefore,  we can provide no assurance that United States
unitholders  will be in a position to make a timely QEF election.  United States
unitholders who purchase our trust units are urged to consult with their own tax
advisors regarding the possible availability of a QEF election.

Foreign Tax Credits

      Regardless of whether the distribution to a United States unitholder under
the Plan is subject to tax under the passive foreign investment company rules or
as  described in "Amount  Capable of  Inclusion in Income",  any tax withheld by
Canadian taxing authorities with respect to the distribution under the Plan may,
subject to a number of complex  limitations,  be claimed as a foreign tax credit
against a United States  unitholder's United States federal income tax liability
or may be claimed as a deduction

                                     - 26 -



for United States federal  income tax purposes.  The limitation on foreign taxes
eligible for credit is calculated separately with respect to specific classes of
income. For this purpose,  dividends the Trust distributes with respect to trust
units  will be  "passive  income"  or,  in the  case of  certain  United  States
unitholders,  "financial  services  income" for taxable years  beginning  before
January 1, 2007. For taxable years beginning after December 31, 2006,  dividends
generally will be "passive  category  income" or "general  category  income" for
purposes  of  computing  the  foreign tax credit  allowable  to a United  States
unitholder.  Because of the complexity of those limitations,  each United States
unitholder  should  consult  its own tax advisor  with  respect to the amount of
foreign taxes that may be claimed as a credit.

United States Information Reporting and Backup Withholding

      Dividends on our trust units paid within the United States or through some
U.S.-related  financial  intermediaries are subject to information reporting and
may be subject to backup withholding, currently at a 28% rate, unless the holder
is a corporation or other exempt recipient or provides a taxpayer identification
number and  certifies  that no loss of  exemption  from backup  withholding  has
occurred.  Information  reporting  requirements and backup  withholding may also
apply to the cash proceeds of a sale of our trust units.

      Backup  withholding is not an additional tax.  Amounts  withheld under the
backup  withholding  rules may be credited against a United States  unitholder's
U.S. tax  liability,  and a unitholder may obtain a refund of any excess amounts
withheld under the backup  withholding rules by filing the appropriate claim for
refund with the IRS.

                   DESCRIPTION OF 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 Toronto Stock Exchange under the symbol  "PWI.UN" and the New York
Stock Exchange under the symbol "PWI".

      The  holders of trust  units are  entitled to one vote for each such trust
unit  at all  meetings  of  unitholders  and are  entitled  to  receive  monthly
distributions of distributable  income on the trust units. All trust units share
equally  in  all  distributions,  carry  equal  voting  rights  at  meetings  of
unitholders  and have a right of redemption on terms set out in the  declaration
of trust.

      The following  table sets forth the price range and trading  volume of the
trust units (adjusted to give effect to the  consolidation of the trust units on
a  four-to-one  basis on August  16,  2002) as  reported  by the  Toronto  Stock
Exchange  and the New York Stock  Exchange  (from the initial date of listing on
the New York Stock Exchange of November 19, 2002) for the periods indicated:

      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

      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 fulfils 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

                                     - 30 -



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

            (c)   is fairly and reasonably entitled to indemnity.

      (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.
