                 PRELIMINARY SHORT FORM BASE SHELF PROSPECTUS

                                      SUBJECT TO COMPLETION, DATED MAY 4, 2006

                               [GRAPHIC OMITTED]
                       [LOGO - PRIMEWEST ENERGY TRUST]


                                  TRUST UNITS

                                 $750,000,000

     PrimeWest  Energy  Trust  (the  "TRUST")  may from time to time offer and
issue  trust  units of the Trust  ("TRUST  UNITS") up to  $750,000,000  in the
aggregate of initial  offering  price (or its equivalent in any other currency
used to  denominate  the Trust Units at the time of the  offering) at any time
during the  25-month  period that this short form base shelf  prospectus  (the
"PROSPECTUS"), including any amendments hereto, remains valid.

     The specific terms of the Trust Units offered will be described in one or
more shelf prospectus supplements  (collectively or individually,  as the case
may be, a "PROSPECTUS SUPPLEMENT"),  including the number of Trust Units being
offered, the offering price and any other specific terms.

     All shelf information  permitted under applicable laws to be omitted from
this Prospectus will be contained in one or more Prospectus  Supplements  that
will be delivered to purchasers together with this Prospectus. Each Prospectus
Supplement  will be  incorporated  by reference  into this  Prospectus for the
purposes of securities legislation as of the date of the Prospectus Supplement
and only for the purposes of the  distribution of the Trust Units to which the
Prospectus  Supplement pertains. A Prospectus  Supplement may include specific
variable  terms  pertaining  to the  Trust  Units  that  are  not  within  the
alternatives and parameters described in this Prospectus.

     NEITHER THE UNITED STATES SECURITIES AND EXCHANGE  COMMISSION (THE "SEC")
NOR ANY STATE  SECURITIES  COMMISSION HAS APPROVED OR DISAPPROVED  THESE TRUST
UNITS  OR  DETERMINED  IF  THIS  PROSPECTUS  IS  TRUTHFUL  OR  COMPLETE.   ANY
REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE.

     THE TRUST IS PERMITTED,  UNDER A  MULTIJURISDICTIONAL  DISCLOSURE  SYSTEM
ADOPTED BY THE UNITED STATES,  TO PREPARE THIS  PROSPECTUS IN ACCORDANCE  WITH
CANADIAN DISCLOSURE  REQUIREMENTS.  PROSPECTIVE INVESTORS SHOULD BE AWARE THAT
SUCH  REQUIREMENTS ARE DIFFERENT FROM THOSE OF THE UNITED STATES.  THE TRUST'S
FINANCIAL  STATEMENTS  INCORPORATED  HEREIN BY REFERENCE HAVE BEEN PREPARED IN
ACCORDANCE WITH CANADIAN GENERALLY ACCEPTED ACCOUNTING PRINCIPLES ("GAAP") AND
ARE SUBJECT TO CANADIAN AUDITING AND AUDITOR  INDEPENDENCE  STANDARDS AND THUS
MAY NOT BE COMPARABLE TO FINANCIAL  STATEMENTS OF UNITED STATES'  COMPANIES OR
TRUSTS.

     PROSPECTIVE  INVESTORS  SHOULD  BE  AWARE  THAT  PURCHASING,  HOLDING  OR
DISPOSING OF ANY OF THE TRUST UNITS MAY SUBJECT  INVESTORS TO TAX CONSEQUENCES
BOTH IN THE UNITED  STATES  AND  CANADA.  THIS  PROSPECTUS  OR ANY  APPLICABLE
PROSPECTUS   SUPPLEMENT  MAY  NOT  DESCRIBE  THESE  TAX  CONSEQUENCES   FULLY.
PROSPECTIVE  INVESTORS  SHOULD READ THE TAX DISCUSSION IN THIS  PROSPECTUS AND
ANY APPLICABLE PROSPECTUS SUPPLEMENT FULLY.

     AN  INVESTOR'S  ABILITY TO  ENFORCE  CIVIL  LIABILITIES  UNDER THE UNITED
STATES FEDERAL  SECURITIES LAWS MAY BE AFFECTED ADVERSELY BECAUSE THE TRUST IS
ORGANIZED  UNDER THE LAWS OF THE  PROVINCE OF ALBERTA,  CANADA,  A MAJORITY OF
PRIMEWEST  ENERGY INC.'S  ("PRIMEWEST")  OFFICERS AND DIRECTORS AND CERTAIN OF
THE EXPERTS NAMED IN THIS  PROSPECTUS ARE RESIDENTS OF CANADA,  AND ALL OF THE
TRUST'S ASSETS AND ALL OR A SIGNIFICANT  PORTION OF THE ASSETS OF SUCH PERSONS
ARE LOCATED OUTSIDE THE UNITED STATES.

     The Trust may sell the Trust Units to or through  underwriters or dealers
purchasing  as  principals,  and may also sell the Trust  Units to one or more
purchasers directly,  pursuant to applicable statutory exemptions,  or through



agents. The Prospectus  Supplement  relating to a particular offering of Trust
Units will identify each underwriter, dealer or agent engaged by the Trust, in
connection  with the offering and sale of the Trust Units,  and will set forth
the terms of the offering of such Trust Units,  the method of  distribution of
such Trust Units,  including,  to the extent  applicable,  the proceeds to the
Trust,  and  any  fees,   discounts  or  any  other  compensation  payable  to
underwriters,  dealers or agents and any other  material  terms of the plan of
distribution. In connection with any offering of Trust Units, the underwriters
or dealers, as the case may be, may over-allot or effect transactions intended
to fix or stabilize  the market price of the Trust Units at a level above that
which  might  otherwise  prevail in the open  market.  Such  transactions,  if
commenced, may be discontinued at any time. See "Plan of Distribution".

     The outstanding Trust Units are listed on the Toronto Stock Exchange (the
"TSX")  under the symbol  "PWI.UN"  and the New York Stock  Exchange  ("NYSE")
under the symbol "PWI".

     The  return on an  investment  in Trust  Units is not  comparable  to the
return on an  investment  in a  fixed-income  security.  The  recovery  of the
initial  investment made by holders of Trust Units (the  "UNITHOLDERS")  is at
risk, and the anticipated return on a Unitholder's investment is based on many
performance assumptions. Although the Trust intends to make distributions of a
portion of its available cash to Unitholders,  these cash distributions may be
reduced or suspended.  The ability of the Trust to make cash distributions and
the actual amount distributed will depend on numerous factors including, among
other  things:  the  financial  performance  of the Trust,  debt  obligations,
working capital requirements and future capital requirements, all of which are
susceptible to a number of risks.  In addition,  the market value of the Trust
Units may decline if the Trust is unable to meet its cash distribution targets
in the future, and that decline may be significant.  Prospective purchasers of
Trust Units also should  consider the particular  risk factors that may affect
the industry in which the Trust  operates,  and therefore the stability of the
distributions that Unitholders receive. See "Risk Factors".  This section also
describes the Trust's  assessment of those risk factors,  as well as potential
consequences to Unitholders if a risk should occur.

     The  offering  of Trust  Units is subject to  approval  of certain  legal
matters on behalf of the Trust by Stikeman Elliott LLP,  Calgary,  Alberta and
Paul,  Weiss,  Rifkind,  Wharton  &  Garrison  LLP,  New York,  New  York.  NO
UNDERWRITER  OR DEALER IN CANADA OR THE UNITED STATES HAS BEEN INVOLVED IN THE
PREPARATION OF THIS PROSPECTUS OR PERFORMED ANY REVIEW OF THE CONTENTS OF THIS
PROSPECTUS.

     THE TRUST  UNITS ARE NOT  "DEPOSITS"  WITHIN  THE  MEANING  OF THE CANADA
DEPOSIT  INSURANCE  CORPORATION  ACT  (CANADA)  AND ARE NOT INSURED  UNDER THE
PROVISIONS OF THAT ACT OR ANY OTHER LEGISLATION. FURTHERMORE, THE TRUST IS NOT
A TRUST COMPANY AND,  ACCORDINGLY,  IT IS NOT  REGISTERED  UNDER ANY TRUST AND
LOAN  COMPANY  LEGISLATION  AS IT DOES NOT  CARRY ON OR INTEND TO CARRY ON THE
BUSINESS OF A TRUST COMPANY.

     The Trust has not obtained a stability rating from an independent  rating
agency regarding the relative stability and sustainability of the Trust's cash
distribution  stream. The Trust may consider obtaining a stability rating from
an independent rating agency in the future.

     The  Trust's  principal  and head  office is located  at 5100,  150 - 6th
Avenue S.W.,  Calgary,  Alberta T2P 3Y7 and PrimeWest's  registered  office is
located at 4300 Bankers Hall West, 888 - 3rd Street S.W., Calgary, Alberta T2P
5C5.

                   NOTE REGARDING FORWARD-LOOKING STATEMENTS

     This  Prospectus  and the  documents  incorporated  by  reference  herein
contain  forward-looking  statements  with  respect  to the  Trust,  including
forward-looking  statements  within the meaning of the United  States  Private
Securities Litigation Reform Act of 1995.

     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 the  forward-looking
statements.

     The Trust and  PrimeWest  believe  the  expectations  reflected  in those
forward-looking  statements  are  reasonable.  However,  neither the Trust nor
PrimeWest can 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 the Trust's 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 the Trust's ability to raise capital and to add to
     the  Trust's   reserves   through   acquisitions   and   exploration  and
     development;

o    The Trust's treatment under governmental regulatory regimes;

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

                                      1


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 intention of maintaining a payout ratio of distributions to cash flow
     from operations within any range;

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;

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    The  Trust's  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
     regulations on the Trust 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    The  Trust's   ability  to  benefit  from  the   combination   of  growth
     opportunities and the ability to grow through the capital markets.

     With respect to forward-looking  statements contained in this Prospectus,
including  the  documents  incorporated  herein  by  reference,  the Trust and
PrimeWest have made assumptions regarding, among other things:

o    Future oil and natural gas prices and differentials between light, medium
     and heavy oil prices;

o    The cost of expanding the Trust's property holdings;

o    The Trust's  ability to obtain  equipment in a timely manner to carry out
     development activities;

o    The   Trust's   ability  to  market  the  Trust's  oil  and  natural  gas
     successfully to current and new customers;

o    The impact of increasing competition;

o    The Trust's ability to obtain financing on acceptable terms; and

o    The Trust's  ability to add production  and reserves  through the Trust's
     development and exploitation activities.

     The Trust's actual results could differ materially from those anticipated
in these forward-looking  statements as a result of the risk factors set forth
below and  elsewhere in this  Prospectus  and the  documents  incorporated  by
reference in 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 the Trust's 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;

                                      2


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  the  Trust's  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 could  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;

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

o    The other  factors  discussed  under  "Risk  Factors"  contained  in this
     Prospectus.

     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.  The
Trust and PrimeWest  undertake no obligation to publicly  update or revise any
forward-looking statements.

         PRESENTATION OF OUR FINANCIAL, RESERVE AND OTHER INFORMATION

     Unless  indicated  otherwise,  financial  information in this Prospectus,
including the documents incorporated by reference herein, has been prepared in
accordance  with  Canadian  GAAP.  Canadian  GAAP differs in some  significant
respects from U.S. GAAP and thus the Trust's  financial  statements may not be
comparable  to the  financial  statements  of U.S.  companies.  The  principal
differences  as they  apply  to the  Trust  are  summarized  in note 20 to the
Trust's annual audited consolidated  financial statements  incorporated herein
by reference.

     The SEC generally  permits oil and gas  companies,  in their filings with
the SEC, to disclose only proved reserves after the deduction of royalties and
interests of others which are those  reserves that a company has  demonstrated
by  actual  production  or  conclusive  formation  tests  to  be  economically
producible  under  existing  economic and operating  conditions.  In 2003, the
securities  regulatory  authorities  in Canada (other than Quebec)  adopted NI
51-101 - STANDARDS OF DISCLOSURE  FOR OIL AND GAS  ACTIVITIES  ("NI  51-101"),
which imposes oil and gas  disclosure  standards for Canadian  public  issuers
engaged in oil and gas activities.  NI 51-101 permits oil and gas issuers,  in
their filings with Canadian securities regulators, to disclose not only proved
reserves but also probable  reserves,  and to disclose reserves and production
on a gross basis before deducting royalties. Probable reserves are of a higher
risk and are less likely to be accurately  estimated or recovered  than proved
reserves.  Because the Trust is permitted to disclose  reserves in  accordance
with  Canadian  disclosure  requirements,  the  Trust  has  disclosed  in this
Prospectus and in the documents  incorporated by reference reserves designated
as "Probable".  If required to be prepared in accordance with U.S.  disclosure
requirements, the SEC's guidelines would prohibit reserves in these categories
from being included. Moreover, in accordance with Canadian practice, The Trust
has determined and disclosed  estimated future net cash flow from its reserves
using both escalated and constant  prices and costs;  for the constant  prices
and costs case,  prices and costs in effect as of December  31, 2005 were held
constant for the economic  life of the  reserves.  The SEC does not permit the
disclosure of estimated future net cash flow from reserves based on escalating
prices and costs and generally requires that prices and costs be held constant
at levels in effect at the date of the reserve report.  Additional information
prepared in accordance  with United States  Statement of Financial  Accounting
Standards No. 69 "Disclosures About Oil and Gas Producing Activities" relating
to the Trust's oil and gas reserves is set forth in the Trust's annual audited
consolidated  financial  statements  incorporated herein by reference.  Unless
otherwise stated, all of the reserves information

                                      3


contained in this Prospectus,  including the documents  incorporated herein by
reference, has been calculated and reported in accordance with NI 51-101.

     Words  importing  the singular  number only include the plural,  and VICE
VERSA, and words importing any gender include all genders.

     All dollar amounts set forth in this Prospectus are in Canadian  dollars,
except where otherwise indicated.

                               NON-GAAP MEASURES

     In this  Prospectus,  including the documents  incorporated  by reference
herein,  the Trust uses the terms "cash flow", "cash flow from operations" and
"cash available for distribution" to refer to the amount of cash available for
distribution to Unitholders and as indicators of financial performance.  "Cash
flow",  "cash flow from operations" and "cash available for  distribution" are
not measures recognized by Canadian GAAP and do not have standardized meanings
prescribed  by  Canadian  GAAP.  Therefore,   "cash  flow",  "cash  flow  from
operations"  and "cash  available  for  distribution"  of the Trust may not be
comparable to similar measures  presented by other issuers,  and investors are
cautioned that "cash flow",  "cash flow from  operations"  and "cash available
for  distribution"  should not be construed as  alternatives  to net earnings,
cash flow from operating activities or other measures of financial performance
calculated in accordance with Canadian GAAP. All references to "cash flow" and
"cash flow from  operations" are based on cash flow before changes in non-cash
working  capital  related  to  operating  activities,   as  presented  in  the
consolidated   financial   statements  of  the  Trust.   Cash   available  for
distribution  cannot be assured and future  distributions  may vary. The Trust
uses such terms, and  particularly  "cash available for  distribution",  as an
indicator of financial performance because such terms are commonly utilized by
investors  to  evaluate  royalty  trusts and  income  funds in the oil and gas
sector.  The Trust believes that "cash available for distribution" is a useful
supplemental measure as it provides investors with information of what cash is
available for distribution from the Trust to Unitholders in such periods.

                            ADDITIONAL INFORMATION

     The Trust has filed with the SEC a registration statement on Form F-10 of
which the Prospectus  forms a part.  This  Prospectus does not contain all the
information set out in the  registration  statement.  For further  information
about  the  Trust  and the  Trust  Units,  please  refer  to the  registration
statement.  The Trust is subject to the information requirements of the United
States  SECURITIES  EXCHANGE ACT OF 1934, as amended (the "EXCHANGE  ACT") and
applicable Canadian securities legislation,  and in accordance therewith,  the
Trust files and furnishes  reports and other information with the SEC and with
the  securities  regulatory  authorities  of the provinces of Canada.  Under a
multi-jurisdictional  disclosure  system  adopted  by the  United  States  and
Canada, the Trust

                                      4


generally may prepare these reports and other  information in accordance  with
the disclosure  requirements of Canada.  These requirements are different from
those of the United States.  As a foreign private issuer,  the Trust is exempt
from the rules under the Exchange Act  prescribing  the furnishing and content
of proxy  statements,  and  PrimeWest's  officers  and  directors,  and  those
Unitholders  holding  10% or more of the  Trust  Units,  are  exempt  from the
reporting and short-swing profit recovery  provisions  contained in Section 16
of the Exchange Act.

     The reports and other  information filed by the Trust with the SEC may be
read and  copied at the SEC's  public  reference  room at 100F  Street,  N.E.,
Washington, D.C. 20549. Copies of the same documents can also be obtained from
the public  reference  room of the SEC in Washington  by paying a fee.  Please
call the SEC at 1-800-SEC-0330 for further information on the public reference
room. The SEC also  maintains a web site  (www.sec.gov)  that makes  available
reports and other  information  that the Trust files  electronically  with it,
including the registration  statement that the Trust has filed with respect to
this offering.

     Copies of reports,  statements and other information that the Trust files
with  the  Canadian   provincial   securities   regulatory   authorities   are
electronically  available  from the Canadian  System for  Electronic  Document
Analysis and Retrieval (www.sedar.com), which is commonly known by the acronym
"SEDAR".  Reports and other information about the Trust are also available for
inspection at the offices of the TSX.

                  ENFORCEABILITY OF CERTAIN CIVIL LIABILITIES

     Both the Trust and  PrimeWest  are  organized  under the laws of Alberta,
Canada with their principal place of business in Canada. Most of the directors
and all of the officers of PrimeWest  and the  representatives  of the experts
named in this  Prospectus  are  residents of Canada,  and all or a substantial
portion of their assets and the Trust's assets are located  outside the United
States. As a result, it may be difficult for investors in the United States to
effect  service of  process  within the  United  States  upon such  directors,
officers and  representatives  of experts who are not  residents of the United
States or to enforce against them judgments of United States courts based upon
civil  liability  under  the  United  States  federal  securities  laws or the
securities  laws of any state within the United  States.  There is doubt as to
the  enforceability in Canada against the Trust or PrimeWest or against any of
PrimeWest's  directors,  officers  or  representatives  of 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 federal  securities  laws or the securities laws of any
state within the United States.

                                 RISK FACTORS

     Prospective  purchasers of the Trust Units should consider  carefully the
risk factors set forth below as well as the other information contained in and
incorporated by reference in this Prospectus and in the applicable  Prospectus
Supplement  before  purchasing  the Trust Units offered  hereby.  If any event
arising from these risks occurs,  the Trust's business,  prospects,  financial
condition,  results of operations or cash flows could be materially  adversely
affected.

RISKS RELATED TO OUR BUSINESS

     VOLATILITY  IN OIL AND NATURAL GAS PRICES  COULD HAVE A MATERIAL  ADVERSE
EFFECT ON RESULTS OF OPERATIONS AND FINANCIAL CONDITION, WHICH, IN TURN, COULD
AFFECT THE MARKET PRICE OF THE TRUST UNITS AND THE AMOUNT OF  DISTRIBUTIONS TO
UNITHOLDERS.

     Results of operations and financial condition are dependent on the prices
received for the oil and natural gas that PrimeWest sells.  Historically,  the
markets for oil and natural gas have been  volatile and are likely to continue
to be volatile in the future.  Oil and natural gas prices may fluctuate widely
on a daily  basis in  response  to a variety  of factors  beyond  the  Trust's
control, including:

o    Global energy  policy,  including the ability of OPEC to set and maintain
     production levels and prices for oil;

o    Political conditions,  including the risk of hostilities in the petroleum
     producing regions of the world;

o    Global and domestic economic conditions;

o    Weather conditions, including weather related natural disasters;

o    The supply and price of imported oil and liquefied natural gas;

o    The production and storage levels of North American natural gas;

o    The level of consumer demand;

o    The price and availability of alternative fuels;

o    The  impact of  US/Canadian  currency  exchange  on the  Canadian  prices
     realized by the Trust;

o    The proximity of reserves to, and capacity of, transportation facilities;

o    The effect of worldwide energy conservation measures; and

o    Government regulations.

     Any  decline  in crude oil or  natural  gas  prices  may have a  material
adverse  effect on  PrimeWest's  operations,  financial  condition,  borrowing
ability,  reserves  and the  level  of  expenditures  for the  development  of
reserves.  Any  resulting  decline  in  PrimeWest's  cash  flow  could  reduce
distributions and the market price of the Trust Units.

     PrimeWest  uses  financial  derivative   instruments  and  other  hedging
mechanisms to attempt to limit a portion of the adverse effects resulting from
changes in oil and  natural  gas  commodity  prices.  To the extent  PrimeWest
hedges its  commodity  price  exposure,  it  foregoes  the  benefits  it would
otherwise  receive  if  commodity  prices  were  to  increase.   In  addition,
commodity-hedging  activities  could expose  PrimeWest to losses.  Such losses
could occur under various  circumstances,  including  those in which the other
party  to a hedge  does not  perform  its  obligations  under  the  applicable
agreement,  the  hedge  is  imperfect  or  PrimeWest's  hedging  policies  and
procedures are not followed.  Furthermore, these hedging transactions will not
fully offset the risks of changes in commodities prices.

                                      7


     AN INCREASE IN  OPERATING  COSTS OR A DECLINE IN  PRIMEWEST'S  PRODUCTION
LEVEL  COULD  HAVE A  MATERIAL  ADVERSE  EFFECT  ON  THE  TRUST'S  RESULTS  OF
OPERATIONS AND FINANCIAL CONDITION AND, THEREFORE,  COULD REDUCE DISTRIBUTIONS
TO UNITHOLDERS AND AFFECT THE MARKET PRICE OF THE TRUST UNITS.

     Higher  operating  costs  associated  with  PrimeWest's  properties  will
directly  decrease  the  amount  of  cash  flow  received  by the  Trust  and,
therefore,  may reduce distributions to Unitholders.  Electricity,  chemicals,
supplies, and reclamation,  abandonment and labour costs are some of the types
of operating costs that are susceptible to material fluctuation.

     The level of  production  from existing  properties  may decline at rates
greater than  anticipated due to unforeseen  circumstances,  many of which are
beyond PrimeWest's  control. A significant  decline in production could result
in materially  lower revenues and cash flow and,  therefore,  could reduce the
amount available for distributions to Unitholders.

     DISTRIBUTIONS  MAY BE REDUCED  DURING  PERIODS IN WHICH  PRIMEWEST  MAKES
CAPITAL  EXPENDITURES  OR DEBT  REPAYMENTS  USING CASH FLOW,  WHICH COULD ALSO
AFFECT THE MARKET PRICE OF THE TRUST UNITS.

     To the extent  that  PrimeWest  uses cash flow to  finance  acquisitions,
development costs and other significant  expenditures,  the net cash flow that
the Trust receives from PrimeWest will be reduced, and, as a consequence,  the
amount  of  cash  available  to  distribute  to  Unitholders   will  decrease.
Distributions  may be reduced,  or even eliminated,  at times when significant
capital or other expenditures are made.

     The board of directors of PrimeWest  has the  discretion to determine the
extent to which cash flow from  PrimeWest  will be allocated to the payment of
debt service charges as well as the repayment of outstanding  debt,  including
debt  under the  Trust's  credit  facility.  The amount of funds  retained  by
PrimeWest to pay debt  services  charges or reduce debt will reduce the amount
of cash distributed to Unitholders  during those periods in which funds are so
retained.

     A DECLINE  IN  PRIMEWEST'S  ABILITY  TO MARKET  ITS OIL AND  NATURAL  GAS
PRODUCTION COULD HAVE A MATERIAL ADVERSE EFFECT ON PRODUCTION LEVELS OR ON THE
PRICE RECEIVED FOR PRODUCTION,  WHICH, IN TURN, COULD REDUCE  DISTRIBUTIONS TO
UNITHOLDERS AND AFFECT THE MARKET PRICE OF THE TRUST UNITS.

     PrimeWest's business depends in part upon the availability, proximity and
capacity  of gas  gathering  systems,  pipelines  and  processing  facilities.
Canadian  federal and provincial,  as well as United States federal and state,
regulation of oil and gas production,  processing and transportation,  tax and
energy policies, general economic conditions, and changes in supply and demand
could  adversely  affect  PrimeWest's  ability to  produce  and market oil and
natural gas. If market factors change and inhibit the marketing of PrimeWest's
production,  overall  production or realized  prices may decline,  which could
reduce distributions to Unitholders.

     FLUCTUATIONS IN FOREIGN  CURRENCY  EXCHANGE RATES COULD ADVERSELY  AFFECT
PRIMEWEST'S BUSINESS,  AND COULD AFFECT THE MARKET PRICE OF THE TRUST UNITS AS
WELL AS DISTRIBUTIONS TO UNITHOLDERS.

     The price that PrimeWest receives for its oil and natural gas is based on
United  States  dollar  denominated  benchmarks,  and therefore the price that
PrimeWest  receives in  Canadian  dollars is  affected  by the  exchange  rate
between the two currencies.  A material  increase in the value of the Canadian
dollar  relative  to the  United  States  dollar  may  negatively  impact  net
production  revenue by decreasing  the Canadian  dollars  received for a given
United States dollar price.  PrimeWest  could also be subject to  unfavourable
price changes to the extent that it has engaged,  or in the future engages, in
risk management  activities  related to foreign exchange rates,  through entry
into forward foreign exchange contracts or otherwise.

     IF PRIMEWEST IS UNABLE TO ACQUIRE ADDITIONAL  RESERVES,  THE VALUE OF THE
TRUST UNITS AND DISTRIBUTIONS TO UNITHOLDERS MAY DECLINE.

     PrimeWest  does not  actively  explore for oil and natural gas  reserves.
Instead,  PrimeWest adds to its reserves  primarily  through  development  and
acquisitions. As a result, future oil and natural gas reserves are

                                      8


highly dependent on PrimeWest's  success in exploiting existing properties and
acquiring  additional  properties.  PrimeWest also distributes the majority of
its net  cash  flow to  Unitholders  rather  than  reinvesting  it in  reserve
additions. Accordingly, if external sources of capital, including the issuance
of additional  Trust Units,  become  limited or  unavailable  on  commercially
reasonable   terms,   PrimeWest's   ability  to  make  the  necessary  capital
investments  to maintain or expand its oil and  natural gas  reserves  will be
impaired. To the extent that PrimeWest is required to use cash flow to finance
capital  expenditures  or  property  acquisitions,  the  level  of  cash  flow
available  for  distribution  to  Unitholders  will be reduced.  Additionally,
PrimeWest cannot guarantee that it will be successful in developing additional
reserves or acquiring  additional  reserves on terms that meet its  investment
objectives. Without these reserve additions, PrimeWest's reserves will deplete
and as a consequence,  either production from, or the average reserve life of,
its properties  will decline.  Either decline may result in a reduction in the
value of Trust Units and in a reduction in cash available for distributions to
Unitholders.

     ACTUAL RESERVES WILL VARY FROM RESERVE  ESTIMATES,  AND THOSE  VARIATIONS
COULD BE  MATERIAL,  AND  AFFECT  THE  MARKET  PRICE OF THE  TRUST  UNITS  AND
DISTRIBUTIONS TO UNITHOLDERS.

     The value of the Trust  Units  depends  upon,  among  other  things,  the
reserves  attributable  to  PrimeWest's  properties.  Estimating  reserves  is
inherently uncertain.  Ultimately, actual reserves attributable to PrimeWest's
properties will vary from estimates, and those variations may be material. The
reserve figures  contained herein are only estimates.  A number of factors are
considered  and a number of  assumptions  are made when  estimating  reserves.
These factors and assumptions include, among others:

o    Historical  production in the areas in which the  properties  are located
     and production rates from similar producing areas;

o    Future commodity prices,  production and development costs, royalties and
     capital expenditures;

o    Initial production rates;

o    Production decline rates;

o    Ultimate recovery of reserves;

o    Success of future development activities;

o    Marketability of production;

o    Effects of government regulation; and

o    Other  government  levies that may be imposed over the producing  life of
     reserves.

     Reserve  estimates  are based on the relevant  factors,  assumptions  and
prices on the date that such estimates are prepared. Many of these factors are
subject  to change  and are  beyond  PrimeWest's  control.  If these  factors,
assumptions  and prices change or prove to be  inaccurate,  actual results may
vary materially from reserve estimates.

     IF PRIMEWEST EXPANDS ITS OPERATIONS BEYOND OIL AND NATURAL GAS PRODUCTION
IN WESTERN  CANADA,  IT MAY FACE NEW  CHALLENGES  AND RISKS.  IF  PRIMEWEST IS
UNSUCCESSFUL IN MANAGING THESE CHALLENGES AND RISKS, ITS RESULTS OF OPERATIONS
AND FINANCIAL  CONDITION COULD BE ADVERSELY  AFFECTED,  WHICH COULD AFFECT THE
MARKET PRICE OF THE TRUST UNITS AND DISTRIBUTIONS TO UNITHOLDERS.

     PrimeWest's   operations   and  expertise   are   currently   focused  on
conventional  oil and gas  production  and  development  in the Western Canada
Sedimentary  Basin. In the future, it may acquire  unconventional  oil and gas
properties outside this geographic area. In addition, the Declaration of Trust
does not limit the activities to oil and gas production and  development,  and
PrimeWest could acquire other energy related  assets,  such as oil and natural
gas processing  plants or pipelines.  Expansion of PrimeWest's  activities may
present  challenges  and risks that it has not faced in the past. If PrimeWest
does not  manage  these  challenges  and risks  successfully,  its  results of
operations and financial condition could be adversely affected.

                                      9


     IN DETERMINING THE PURCHASE PRICE OF  ACQUISITIONS,  PRIMEWEST  RELIES ON
ASSESSMENTS RELATING TO ESTIMATES OF RESERVES THAT MAY PROVE TO BE INACCURATE,
WHICH COULD  AFFECT THE MARKET PRICE OF THE TRUST UNITS AND  DISTRIBUTIONS  TO
UNITHOLDERS.

     The price PrimeWest is willing to pay for an acquisition is based largely
on  estimates  of the  reserves to be  acquired.  Actual  reserves  could vary
materially from these estimates. Consequently, the reserves PrimeWest acquires
may be less  than  expected,  which  could  adversely  impact  cash  flows and
distributions to Unitholders.

     An  initial  assessment  of an  acquisition  may be based on a report  by
engineers or firms of engineers  that have  different  evaluation  methods and
approaches than those of PrimeWest's engineers,  and these initial assessments
may differ significantly from PrimeWest's subsequent assessments.

     PRIMEWEST DOES NOT OPERATE SOME OF ITS PROPERTIES AND THEREFORE,  RESULTS
OF  OPERATIONS  MAY BE  ADVERSELY  AFFECTED  BY  THE  FAILURE  OF  THIRD-PARTY
OPERATORS,  WHICH  COULD  AFFECT  THE  MARKET  PRICE OF THE  TRUST  UNITS  AND
DISTRIBUTIONS TO UNITHOLDERS.

     The  continuing  production  from a  property,  and to  some  extent  the
marketing of that  production,  is dependent upon the ability of the operators
of those  properties.  At December 31, 2005,  approximately 20% of PrimeWest's
daily production came from properties operated by third parties. To the extent
that a third party  operator  fails to perform its  functions  efficiently  or
becomes insolvent, PrimeWest's operating income may be reduced.

     Further, the operating agreements that govern the properties not operated
by PrimeWest  typically  require the operator to conduct  operations in a good
and  "workmanlike"  manner.  These  operating  agreements  generally  provide,
however, that the operator has no liability to the other non-operating working
interest  owners,  for losses  sustained or liabilities  incurred,  except for
liabilities that may result from gross negligence or wilful misconduct.

     DELAYS IN BUSINESS  OPERATIONS  COULD ADVERSELY  AFFECT  DISTRIBUTIONS TO
UNITHOLDERS AND THE MARKET PRICE OF THE TRUST UNITS.

     In  addition  to the usual  delays in  payment by  purchasers  of oil and
natural gas to  PrimeWest  and to the  operators of  PrimeWest's  non-operated
properties,  and the  delays  of  those  operators  in  remitting  payment  to
PrimeWest, payments between any of these parties may also be delayed by:

o    Restrictions imposed by lenders;

o    Accounting delays;

o    Delays in the sale or delivery of products;

o    Delays in the connection of wells to a gathering system;

o    Blowouts or other accidents;

o    Adjustments for prior periods;

o    Recovery by the  operator of expenses  incurred in the  operation  of the
     properties; or

o    The establishment by the operator of reserves for these expenses.

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

     THE TRUST AND PRIMEWEST'S  INDEBTEDNESS MAY LIMIT THE TIMING OR AMOUNT OF
THE  DISTRIBUTIONS  THAT ARE PAID TO UNITHOLDERS,  AND COULD AFFECT THE MARKET
PRICE OF THE TRUST UNITS.

     The payments of interest  and  principal,  and other costs,  expenses and
disbursements  made to the  providers of the Trust's  credit  facility  reduce
amounts available for distribution to Unitholders. Variations in

                                      10


interest rates and scheduled principal  repayments could result in significant
changes  to  the  amount  of  the  cash  flow  available  for  payment  to the
Unitholders in any given period.  The agreements  governing the Trust's credit
facility  provide  that if the Trust or  PrimeWest  are in  default  under the
Trust's credit facility, exceed certain borrowing thresholds or fail to comply
with certain  covenants,  they must repay the  indebtedness  at an accelerated
rate,  and the ability to make  distributions  to  Unitholders  may be further
restricted.

     The lenders under the Trust's  credit  facility have been provided with a
security interest in substantially all of the Trust and PrimeWest's assets. If
the  Trust  and  PrimeWest  are  unable  to pay the debt  service  charges  or
otherwise  commit an event of default,  such as bankruptcy,  these lenders may
foreclose  on and sell  the  properties.  The  proceeds  of any sale  would be
applied to satisfy  amounts owed to the creditors.  Only after the proceeds of
that sale were  applied  towards  the debt  would the  remainder,  if any,  be
available for distribution to Unitholders.

     THE CURRENT CREDIT FACILITY AND ANY  REPLACEMENT  CREDIT FACILITY MAY NOT
PROVIDE SUFFICIENT LIQUIDITY.

     The amounts  available  under the  existing  credit  facility  may not be
sufficient for future  operations,  or the Trust and PrimeWest may not be able
to obtain  additional  financing on economic  terms  attractive to them, if at
all. A portion of the  existing  credit  facility is  available  on a one-year
revolving  basis.  If the lenders do not extend the facility at the end of the
annual revolving period, the loan will convert to a term basis with 60% of the
aggregate principal amount of the loan repayable on the date which is 366 days
after that  conversion  date and the remaining 40% of the aggregate  principal
amount  outstanding  repayable on the date which is 365 days after the initial
term  repayment  date.  If this occurs,  the Trust and  PrimeWest  may need to
obtain  alternate  financing.  Any  failure  to  obtain  suitable  replacement
financing  may  have  a  material   adverse   effect  on  the  business,   and
distributions to Unitholders may be materially reduced.

     THE TRUST MAY BE UNABLE TO SUCCESSFULLY  COMPETE WITH OTHER ORGANIZATIONS
IN THE  TRUST'S  INDUSTRY,  WHICH COULD  AFFECT THE MARKET  PRICE OF THE TRUST
UNITS AND DISTRIBUTIONS TO UNITHOLDERS.

     The oil  and  natural  gas  industry  is  highly  competitive.  PrimeWest
competes for capital,  acquisitions of reserves,  undeveloped  lands,  skilled
personnel,  access to drilling rigs, service rigs and other equipment,  access
to  processing  facilities,  pipeline and refining  capacity and in many other
respects with a substantial number of other  organizations,  many of which may
have greater technical and financial  resources than PrimeWest.  Some of these
organizations  explore  for  develop  and produce oil and natural gas but also
carry on refining  operations and market oil and other products on a worldwide
basis.  As a result of these  complementary  activities,  some of  PrimeWest's
competitors may have greater and more diverse competitive resources to draw on
than PrimeWest does.

     THE INDUSTRY IN WHICH PRIMEWEST  OPERATES EXPOSES THE TRUST AND PRIMEWEST
TO POTENTIAL LIABILITIES THAT MAY NOT BE COVERED BY INSURANCE.

     PrimeWest's  operations are subject to all of the risks  associated  with
the operation and development of oil and natural gas properties, including the
drilling of oil and natural gas wells,  and the production and  transportation
of  oil  and  natural  gas.  These  risks  and  hazards  include  encountering
unexpected  formations or pressures,  blow outs,  craterings and fires, all of
which could result in personal  injury,  loss of life,  or  environmental  and
other damage to  PrimeWest's  property  and the property of others.  PrimeWest
cannot fully  protect  against all of these risks,  nor are all of these risks
insurable. While PrimeWest's insurance broker is responsible for ensuring that
insurance  underwriters  have the financial  strength  necessary to respond to
claims,  PrimeWest may become liable for damages  arising from events  against
which  PrimeWest  cannot  insure or against  which  PrimeWest may elect not to
insure because of high premium costs or other  reasons.  Any costs incurred to
repair these damages or pay these liabilities would reduce funds available for
distribution to Unitholders.

     THE  OPERATION  OF OIL AND NATURAL GAS WELLS COULD  SUBJECT  PRIMEWEST TO
ENVIRONMENTAL CLAIMS AND LIABILITY.

     The oil and natural gas  industry is subject to  extensive  environmental
regulation pursuant to local, provincial and federal legislation.  A breach of
that legislation may result in the imposition of fines or the issuance

                                      11


of "clean up" orders.  Legislation regulating the oil and natural gas industry
may be  changed  to  impose  higher  standards  and  potentially  more  costly
obligations. For example, the Kyoto Protocol will require, among other things,
significant  reductions in greenhouse  gases. The impact of the Kyoto Protocol
on PrimeWest  is  uncertain  and may result in  significant  additional  costs
(future) for  PrimeWest's  operations.  Although  PrimeWest has  established a
reclamation fund for the purpose of funding the estimated future environmental
and  reclamation  obligations  based on current  knowledge  and  expectations,
PrimeWest  cannot  guarantee that it will be able to satisfy its actual future
environmental and reclamation obligations.

     PrimeWest  is not fully  insured  against  certain  environmental  risks,
either  because  such  insurance  is not  available or because of high premium
costs. In particular,  insurance  against risks from  environmental  pollution
occurring  over time (as  opposed to sudden and  catastrophic  damages) is not
available  on  economically   reasonable   terms.   Accordingly,   PrimeWest's
properties  may be subject to liability  due to hazards that cannot be insured
against,  or that have not been  insured  against due to  prohibitive  premium
costs or for other reasons.

     Any site  reclamation  or  abandonment  costs  actually  incurred  in the
ordinary  course of business  in a specific  period will be funded out of cash
flow and,  therefore,  will reduce the amounts  available for  distribution to
Unitholders. Should PrimeWest be unable to fully fund the cost of remedying an
environmental  problem,  PrimeWest might be required to suspend  operations or
enter into interim  compliance  measures  pending  completion  of the required
remedy.

     LOWER OIL AND GAS PRICES  INCREASE THE RISK OF WRITE-DOWNS OF PRIMEWEST'S
OIL AND GAS PROPERTY INVESTMENTS.

     Under Canadian  accounting rules, the net capitalized cost of oil and gas
properties  may not  exceed a "ceiling  limit"  that is based,  in part,  upon
estimated  future net cash flows from reserves.  If oil and natural gas prices
decline,  PrimeWest's  net  capitalized  cost may  exceed  this cost  ceiling,
ultimately  resulting in a charge  against  PrimeWest's  earnings.  Under U.S.
GAAP, the cost ceiling is generally lower than under Canadian GAAP because the
future net cash flows used in the United States ceiling test are discounted to
a present value. Accordingly, PrimeWest would have more risk of a ceiling test
write-down in a declining  price  environment  if it reported under U.S. GAAP.
While  these  write-  downs  would not affect  cash flow,  the charge  against
earnings could be viewed unfavourably in the market.

     UNFORESEEN  TITLE  DEFECTS  MAY  RESULT  IN  A  LOSS  OF  ENTITLEMENT  TO
PRODUCTION AND RESERVES.

     PrimeWest  conducts  title reviews in accordance  with industry  practice
prior to any  purchase  of  resource  assets.  However,  these  reviews do not
guarantee  that an unforeseen  defect in the chain of title will not arise and
defeat  PrimeWest's  title to the purchased  assets.  If such a defect were to
arise,  PrimeWest's  entitlement  to the production  from the affected  assets
could be jeopardized  and, as a result,  distributions  to Unitholders  may be
reduced.

     THE  ECONOMIC  IMPACT  ON  PRIMEWEST  OF CLAIMS  OF  ABORIGINAL  TITLE IS
UNKNOWN.

     Aboriginal  people  have  claimed   aboriginal  title  and  rights  to  a
substantial  portion  of  western  Canada.  PrimeWest  is unable to assess the
effect, if any, that any such claim would have on its business and operations.

RISKS RELATED TO THE TRUST STRUCTURE AND THE OWNERSHIP OF TRUST UNITS

     CHANGES IN TAX AND OTHER LAWS MAY ADVERSELY AFFECT UNITHOLDERS.

     Income tax laws, other laws or government  incentive programs relating to
the oil and gas  industry,  such as the  treatment  of mutual  fund trusts and
resource  allowance,  may in the future be changed or  interpreted in a manner
that  adversely  affects the Trust and  Unitholders.  Tax  authorities  having
jurisdiction over the Trust or the Unitholders may disagree with the manner in
which the Trust  calculates  its income for tax purposes or could change their
administrative  practices  to the Trust's  detriment  or the  detriment of its
Unitholders.

                                      12


     THERE WOULD BE MATERIAL  ADVERSE TAX  CONSEQUENCES  IF THE TRUST LOST ITS
STATUS AS A MUTUAL FUND TRUST UNDER CANADIAN TAX LAWS.

     It is intended that the Trust  continue to qualify as a mutual fund trust
for  purposes of the INCOME TAX ACT  (Canada)  (the "TAX ACT").  The Trust may
not,  however,  always be able to  satisfy  any  future  requirements  for the
maintenance  of mutual fund trust status.  Should the status of the Trust as a
mutual  fund  trust  be lost or  successfully  challenged  by a  relevant  tax
authority,   certain  adverse   consequences  may  arise  for  the  Trust  and
Unitholders.  Some of the significant consequences of losing mutual fund trust
status are as follows:

o    The  Trust  would be taxed on  certain  types of  income  distributed  to
     Unitholders, including income generated by the Royalty held by the Trust.
     Payment of this tax may have adverse  consequences for some  Unitholders,
     particularly  Unitholders  that are not residents of Canada and residents
     of Canada that are otherwise exempt from Canadian income tax.

o    Trust Units held by  Unitholders  that are not  residents of Canada would
     become taxable Canadian  property.  These  non-resident  holders would be
     subject to Canadian  income tax on any gains realized on a disposition of
     Trust Units held by them.

o    The Trust Units would not constitute qualified investments for Registered
     Retirement Savings Plans, or "RRSPs", Registered Retirement Income Funds,
     or "RRIFs",  Registered  Education  Savings Plans, or "RESPs" or Deferred
     Profit Sharing  Plans,  or "DPSPs".  If, at the end of any month,  one of
     these exempt plans holds Trust Units that are not qualified  investments,
     the plan must pay a tax equal to 1% of the fair market value of the Trust
     Units at the time the Trust Units were  acquired by the exempt  plan.  An
     RRSP or RRIF  holding  non-qualified  Trust  Units  would be  subject  to
     taxation on income  attributable  to the Trust Units,  including the full
     amount of any capital gain  realized on a  disposition  of  non-qualified
     Trust  Units by the RRSP or RRIF.  If an RESP holds  non-qualified  Trust
     Units, it may have its registration revoked by the Canada Revenue Agency.

     The Trust may take certain measures in the future to the extent the Trust
believes  them  necessary to ensure that it  maintains  its status as a mutual
fund trust. These measures could be adverse to certain holders of Trust Units.

     RIGHTS AS A UNITHOLDER  DIFFER FROM THOSE  ASSOCIATED WITH OTHER TYPES OF
INVESTMENTS.

     The Trust Units do not represent a traditional  investment in the oil and
natural  gas sector and  should  not be viewed by  investors  as shares in the
Trust or PrimeWest.  The Trust Units represent an equal fractional  beneficial
interest in the Trust and, as such,  the ownership of the Trust Units does not
provide  Unitholders  with  the  statutory  rights  normally  associated  with
ownership of shares of a  corporation,  including,  for example,  the right to
bring  "oppression"  or  "derivative"  actions.  The  unavailability  of these
statutory  rights may also  reduce the  ability of  Unitholders  to seek legal
remedies against other parties on PrimeWest's behalf.

     The Trust Units are also unlike  conventional  debt  instruments  in that
there is no principal  amount owing to Unitholders.  The Trust Units will have
minimal  value when  reserves  from  PrimeWest's  properties  can no longer be
economically  produced or marketed.  Unitholders will only be able to obtain a
return of the capital  they  invested  during the period when  reserves may be
economically recovered and sold. Accordingly,  the distributions received over
the  life  of the  investment  may not  meet or  exceed  the  initial  capital
investment.

     THE LIMITED LIABILITY OF UNITHOLDERS IS UNCERTAIN.

     On July 1, 2004 a new statute  entitled the INCOME  TRUSTS  LIABILITY ACT
(Alberta)  was  proclaimed  in force,  creating a statutory  limitation on the
liability  of  unitholders  of Alberta  income  trusts such as the Trust.  The
legislation  provides that a Unitholder is not, as a  beneficiary,  liable for
any act,  default,  obligation  or  liability of the Trustee that arises after
July 1, 2004.

     However, because of prior uncertainties in the law relating to investment
trusts,  there is a risk that a Unitholder could be held personally liable for
obligations of the Trust in respect of contracts or undertakings

                                      13


which the Trust  entered into and for certain  liabilities  arising  otherwise
than out of contracts  including claims in tort, claims for taxes and possibly
certain other statutory  liabilities  arising prior to July 1, 2004.  Although
every  written  contract or  commitment  of the Trust must  contain an express
disavowal  of liability of the  Unitholders  and a limitation  of liability to
Trust property, such protective provisions may not operate to avoid Unitholder
liability  for  the  relevant  period.   Notwithstanding   attempts  to  limit
Unitholder  liability,  Unitholders may not be protected from such liabilities
to the same extent that a shareholder is protected  from the  liabilities of a
corporation.  Further,  although  the Trust has agreed to  indemnify  and hold
harmless  each  Unitholder  from any costs,  damages,  liabilities,  expenses,
charges and losses suffered by the Unitholder resulting from or arising out of
that Unitholder not having limited liability,  the Trust cannot guarantee that
any assets would be available in these circumstances to reimburse  Unitholders
for any such liability.

     CHANGES IN MARKET-BASED FACTORS MAY ADVERSELY AFFECT THE TRADING PRICE OF
TRUST UNITS.

     The  market  price  of  the  Trust  Units  is  primarily  a  function  of
anticipated distributions to Unitholders and the value of the properties owned
by PrimeWest  and the Trust.  The market price of the Trust Units is therefore
sensitive to a variety of market-based factors, including, but not limited to,
interest  rates  and the  comparability  of the  Trust  Units to  other  yield
oriented  securities.  Any changes in these market-based factors may adversely
affect the trading price of the Trust Units.

     THE OPERATION OF THE TRUST IS ENTIRELY  INDEPENDENT  FROM THE UNITHOLDERS
AND LOSS OF KEY MANAGEMENT AND OTHER PERSONNEL COULD IMPACT THE BUSINESS.

     Unitholders  are entirely  dependent on the  management of the Trust with
respect  to  the  acquisition  of oil  and  gas  properties  and  assets,  the
development  and  acquisition  of  additional  reserves,  the  management  and
administration   of  all   matters   relating  to  the   properties   and  the
administration  of the Trust.  The loss of the services of key individuals who
currently  comprise the management team could have a detrimental effect on the
Trust. Investors should carefully consider whether they are willing to rely on
the existing management before investing in the Trust Units.

     THERE MAY BE FUTURE DILUTION.

     One of the  Trust's  objectives  is to  continually  add to its  resource
reserves through acquisitions and through development.  Because the Trust does
not reinvest the majority of its cash flow, its success is, in part, dependent
on its  ability to raise  capital  from time to time by selling  Trust  Units.
Unitholders  will suffer  dilution as a result of Trust Unit offerings if, for
example,  the cash flow,  production or reserves  from acquired  assets do not
reflect the  additional  number of Trust Units issued to acquire those assets.
Dilution may also occur if the  deployment of funds raised through the various
components of the Trust's  distribution  reinvestment  plan does not result in
the creation of additional value for Unitholders.

     THERE MAY NOT ALWAYS BE AN ACTIVE  TRADING  MARKET IN THE  UNITED  STATES
AND/OR CANADA FOR THE TRUST UNITS.

     While there is currently an active  trading market for the Trust Units in
both the United States and Canada,  the Trust cannot  guarantee that an active
trading market will be sustained in either country.

     THE REDEMPTION RIGHT OF UNITHOLDERS IS LIMITED.

     Unitholders have a limited right to require the Trust to repurchase their
Trust Units,  which is referred to as a redemption  right.  It is  anticipated
that the redemption right will not be the primary mechanism for Unitholders to
liquidate their investment. The Trust's ability to pay cash in connection with
redemption is subject to limitations. Any securities, which may be distributed
in specie to Unitholders in connection with  redemption,  may not be listed on
any stock  exchange  and a market may not develop for such  securities.  Also,
such securities (or some of them) may not be a qualified investment for RRSPs,
RRIFs, DPSPs or RESPs. In addition,  there may be resale restrictions  imposed
by law upon the recipients of the securities pursuant to the redemption right.

                                      14


                            PRIMEWEST ENERGY TRUST

THE TRUST

     The  Trust is an  open-end  investment  trust  created  under the laws of
Alberta  pursuant to a declaration of trust dated as of August 2, 1996,  among
the settlor of the Trust,  PrimeWest and Montreal Trust Company of Canada,  as
amended and restated (the "DECLARATION OF TRUST"). Computershare Trust Company
of Canada is the trustee of the Trust (the  "TRUSTEE").  The  beneficiaries of
the  Trust are the  Unitholders.  The  Trust's  principal  and head  office is
located at 5100, 150 - 6th Avenue S.W., Calgary, Alberta T2P 3Y7.

     The principal  undertaking of the Trust is to acquire and hold,  directly
and  indirectly,  interests  in oil and  natural  gas  properties.  One of the
Trust's  primary  assets is  currently  a  royalty  (the  "ROYALTY")  equal to
approximately  99% of the net cash flow  generated  by the oil and natural gas
interests  held  from  time to time by  PrimeWest,  after  certain  costs  and
deductions.  See "Description of the Royalty" below. A portion of the net cash
flow received by the Trust is distributed  monthly to  Unitholders.  The Trust
also lends money to  PrimeWest to allow it to make  further  acquisitions  and
develop  its  properties.  The  interest  income  earned on such funds is also
distributed monthly to Unitholders.

     The structure of the Trust and the flow of funds from the oil and natural
gas  properties  owned by  PrimeWest  to the  Trust,  and  from  the  Trust to
Unitholders,  is set forth in more  detail  on page 1 of the AIF  incorporated
herein by reference under the heading "Organization - Trust Structure".

PRIMEWEST

     PrimeWest was incorporated under the BUSINESS  CORPORATIONS ACT (Alberta)
(the "ABCA") on March 4, 1996 and was  amalgamated  with PrimeWest Oil and Gas
Corp.,  PrimeWest  Royalty Corp.  and PrimeWest  Resources  Ltd. on January 1,
2002,  with PrimeWest  Management  Inc. and another  subsidiary on November 6,
2002 and  with  PrimeWest  Gas  Corp.  on  December  31,  2005,  in each  case
continuing as PrimeWest Energy Inc. The head and principal office of PrimeWest
is located at 5100,  150 - 6th Avenue S.W.,  Calgary,  Alberta T2P 3Y7. All of
the issued and  outstanding  voting shares of PrimeWest are currently  held by
the Trust.

     The business of PrimeWest is the acquisition, development,  exploitation,
production  and  marketing  of oil and natural gas and granting the Royalty to
the Trust.

     The capital  structure of  PrimeWest  includes  exchangeable  shares (the
"EXCHANGEABLE SHARES"). The Exchangeable Shares were issued in connection with
previous  corporate  acquisitions.  As at May 2, 2006,  there were  issued and
outstanding 1,175,935 Exchangeable Shares, which are exchangeable into 691,532
Trust Units based on a ratio which is adjusted and increased on each date that
the Trust pays a  distribution  to its  Unitholders.  As at May 2,  2006,  the
exchange  ratio was  0.58807  Trust  Units for each  Exchangeable  Share.  The
outstanding Exchangeable Shares are traded on the TSX under the trading symbol
"PWX".

                                USE OF PROCEEDS

     The Trust Units will be issued from time to time at the discretion of the
Trust with an aggregate  offering amount not to exceed  $750,000,000.  The net
proceeds  derived  from the issue of the  Trust  Units  under  any  Prospectus
Supplement  will be the aggregate  offering amount thereof less any commission
and other issuance costs paid in connection therewith. The net proceeds cannot
be  estimated  as the amount  thereof  will  depend on the extent to which the
Trust  Units are issued  under any  Prospectus  Supplement.  Unless  otherwise
specified in the applicable  Prospectus  Supplement,  the net proceeds will be
added to the general funds of the Trust and will be used for general  business
purposes.

                          DESCRIPTION OF TRUST UNITS

     The following is a summary of the material attributes and characteristics
of the Trust  Units.  This  summary  does not  purport to be  complete  and is
subject to, and qualified in its entirety by, reference to the terms

                                      15


of  the  Declaration  of  Trust.  A  summary  of  certain  provisions  of  the
Declaration of Trust, in addition to those establishing the terms of the Trust
Units, is contained in Item 1 of the AIF incorporated herein by reference.

     Each Trust Unit represents an equal undivided  beneficial interest in the
Trust. Each Trust Unit shares equally in all distributions  from the Trust and
all Trust Units carry equal voting rights at meetings of  Unitholders.  Except
as otherwise set forth in the documents  incorporated herein by reference,  no
Unitholder is liable to pay any further calls or assessments in respect of the
Trust Units and no conversion,  retraction,  redemption or pre-emptive  rights
attach to the Trust Units.  Unitholders  have a right of redemption as further
described  under  the  heading  "-  Redemption  Right"  in  Item 1 of the  AIF
incorporated herein by reference.

     An unlimited number of Trust Units have been authorized and may be issued
pursuant to the Declaration of Trust. At April 24, 2006, there were 80,906,609
Trust Units  outstanding.  The  Declaration of Trust provides for, among other
things,  the  calling of  meetings  of  Unitholders,  the  conduct of business
thereof, notice provisions,  the appointment and removal of the trustee of the
Trust and the form of Trust Unit certificates. The Declaration of Trust may be
amended from time to time. Substantive amendments to the Declaration of Trust,
including  early  termination  of the  Trust and the sale or  transfer  of the
property of the Trust as an entirety or  substantially  as an  entirety,  will
require  approval by a special  meeting of  Unitholders  at which a resolution
must be passed by a majority of not less than 66% of the votes cast, either in
person or by proxy, at such meeting.

CASH DISTRIBUTIONS

     Unitholders  of record on the fifth trading day following the 15th day of
each month are entitled to receive cash distributions of distributable  income
of the Trust in respect of that month. Such distributions are made on or about
the 15th day of the  following  month.  The Trust has not obtained a stability
rating from an independent  rating agency regarding the relative stability and
sustainability of the Trust's cash distribution stream. The Trust may consider
obtaining a stability rating from an independent  rating agency in the future.
See also "Cash Distributions on Trust Units" below.

CONSTRAINTS ON NON-RESIDENT OWNERSHIP OF TRUST UNITS

     In order to provide PrimeWest with a measure of flexibility in responding
to evolving positions within the Government of Canada's  Department of Finance
on appropriate  levels of ownership of Trust Units by non-residents of Canada,
the Declaration of Trust provides:

(a)  if at any time the board of  directors of  PrimeWest  determines,  in its
     sole discretion,  or becomes aware,  that the Trust's ability to continue
     to rely on paragraph  132(7)(a) of the Tax Act for purposes of qualifying
     as a "mutual fund trust" thereunder is in jeopardy,  then the Trust shall
     not be maintained  primarily for the benefit of  non-residents  of Canada
     and it shall be the sole  responsibility  of  PrimeWest  to  monitor  the
     holdings by  non-residents of Canada and take such steps as are necessary
     or desirable to ensure that the Trust is not maintained primarily for the
     benefit of non-residents of Canada;

(b)  PrimeWest  may  request  that the Trustee  make  reasonable  efforts,  as
     practicable in the circumstances, to obtain declarations as to beneficial
     ownership,  perform  residency  searches  of  Unitholder  and  beneficial
     Unitholder  mailing  address lists and take such other steps specified by
     PrimeWest to determine or estimate as best  possible the residence of the
     beneficial owners of Trust Units; and

(c)  If at any  time  the  board  of  directors  of  PrimeWest,  in  its  sole
     discretion,  determines  that it is in the best  interest  of the  Trust,
     PrimeWest  may,  notwithstanding  the ability of the Trust to continue to
     rely on paragraph 132(7)(a) of the Tax Act:

     (i)   require  the Trustee to refuse to accept a  subscription  for Trust
           Units  from,  or issue or  register a transfer of Trust Units to, a
           person unless the person  provides a declaration  to PrimeWest that
           the Trust Units to be issued or transferred to such person will not
           when issued or transferred be beneficially  owned by a non-resident
           of Canada;

                                      16


     (ii)  to the extent  practicable in the  circumstances,  send a notice to
           registered  holders of Trust Units which are beneficially  owned by
           non-residents  of Canada,  chosen in inverse  order to the order of
           acquisition or registration of such Trust Units  beneficially owned
           by non-residents of Canada or in such other manner as PrimeWest may
           consider  equitable and  practicable,  requiring them to sell their
           Trust Units which are beneficially owned by non-residents of Canada
           or a specified  portion  thereof  within a specified  period of not
           less than 60 days. If the  Unitholders  receiving  such notice have
           not sold the  specified  number  of such  Trust  Units or  provided
           PrimeWest with satisfactory  evidence that such Trust Units are not
           beneficially owned by non-residents  within such period,  PrimeWest
           may, on behalf of such registered Unitholder, sell such Trust Units
           and, in the  interim,  suspend the voting and  distribution  rights
           attached to such Trust Units and make any  distribution  in respect
           of such Trust Units by  depositing  such amount in a separate  bank
           account in a Canadian chartered bank (net of any applicable taxes).
           Any sale  shall be made on any  stock  exchange  on which the Trust
           Units are then listed and,  upon such sale,  the  affected  holders
           shall  cease to be holders of Trust  Units so disposed of and their
           rights shall be limited to receiving the net proceeds of sale,  and
           any distribution in respect thereof deposited as aforesaid,  net of
           applicable   taxes  and  costs  of  sale,  upon  surrender  of  the
           certificates representing such Trust Units;

     (iii) delist the Trust Units from any non-Canadian stock exchange; and

     (iv)  take such other  actions  as the board of  directors  of  PrimeWest
           determines,  in  its  sole  discretion,   are  appropriate  in  the
           circumstances  that will  reduce or limit the number of Trust Units
           held by  non-resident  Unitholders  to ensure that the Trust is not
           maintained primarily for the benefit of non-residents of Canada.

                          DESCRIPTION OF THE ROYALTY

     The Trust's primary  sources of net cash flow are payments  received from
the Royalty  issued to the Trust by PrimeWest on the  production  from its oil
and natural gas properties and interest and principal  payments on debt issued
to  the  Trust  by  PrimeWest.  For a  complete  description  of  the  Royalty
prospective  purchasers  should  refer to the Royalty  Agreements  (as defined
below), copies of which are available on SEDAR and at www.sec.gov.

     The Royalty is payable to the Trust under a royalty agreement between the
Trust and  PrimeWest  and a royalty  agreement  between  PrimeWest and a prior
subsidiary  of  PrimeWest   that  was  assigned  by  PrimeWest  to  the  Trust
(collectively, the "ROYALTY AGREEMENTS").  Pursuant to the Royalty Agreements,
PrimeWest  is  required  to pay to the Trust the  Royalty  with  respect  to a
particular  month on the 15th day (or the next business day if the 15th is not
a business day) of the month  following.  The Royalty is in an amount equal to
99% of the  aggregate  of the  production  revenues  generated  by the oil and
natural gas  interests  held from time to time by PrimeWest  and certain other
revenues, net of certain permitted costs and deductions.  The Royalty does not
constitute an interest in land.

     The Royalty  created by the Royalty  Agreements  attaches not only to the
properties presently owned by PrimeWest,  but also to the properties PrimeWest
acquires from time to time. In the event of a future acquisition,  the Royalty
Agreements  require  the Trust to make  certain  payments to  PrimeWest  in an
amount equal to 99% of the aggregate of the portion of the  acquisition  costs
attributable  to  Canadian  resource  properties  and  certain of the  capital
expenditures in respect of the properties  being acquired.  These payments are
referred to as "deferred  purchase price obligations" and are payable provided
that,  among other  things,  the Trust is able to fund the  deferred  purchase
price obligations from the issuance of additional Trust Units, borrowings, the
proceeds of dispositions from other properties or the proceeds of dispositions
of the royalty sold in a concurrent  disposition.  As a result of the deferred
purchase price  obligation,  the Trust will provide  PrimeWest with 99% of the
funding it requires to acquire additional resource  properties.  The remaining
1% of the cost of such  properties  will be borne by  PrimeWest  using its own
working capital or funds borrowed by it for such purposes.

                                      17


                             PLAN OF DISTRIBUTION

     The Trust may sell the Trust Units (i) through  underwriters  or dealers,
(ii)  directly  to one or more  purchasers  pursuant to  applicable  statutory
exemptions, or (iii) through agents in Canada, the United States and elsewhere
where permitted by law for cash or other consideration. The Trust Units may be
sold at fixed  prices  or  non-fixed  prices,  such as  prices  determined  by
reference to the prevailing price of the Trust Units in a specified market, at
market  prices  prevailing  at the time of sale or at prices to be  negotiated
with  purchasers,  which prices may vary as between  purchasers and during the
period of distribution of the Trust Units.  The Prospectus  Supplement for any
of the  Trust  Units  being  offered  thereby  will set forth the terms of the
offering of such Trust Units, including the name or names of any underwriters,
dealers or agents, the purchase price of such Trust Units, the proceeds to the
Trust from such sale, any underwriting  discounts and other items constituting
underwriters'  compensation,  any public  offering  price and any discounts or
concessions  allowed  or  re-allowed  or  paid  to  dealers  or  agents.  Only
underwriters so named in the relevant  Prospectus  Supplement are deemed to be
underwriters in connection with the Trust Units offered thereby.

     If underwriters are used in the sale, the Trust Units will be acquired by
the  underwriters for their own account and may be resold from time to time in
one or more transactions, including negotiated transactions, at a fixed public
offering  price or at  varying  prices  determined  at the  time of sale.  The
obligations of the  underwriters  to purchase such Trust Units will be subject
to certain  conditions  precedent,  and the underwriters  will be obligated to
purchase all the Trust Units  offered by the  Prospectus  Supplement if any of
such Trust Units are purchased. Any public offering price and any discounts or
concessions  allowed or re-allowed or paid to dealers may be changed from time
to time.

     In  connection  with any offering of Trust  Units,  the  underwriters  or
dealers, as the case may be, may over-allot or effect transactions intended to
fix or  stabilize  the market  price of the Trust  Units at a level above that
which  might  otherwise  prevail in the open  market.  Such  transactions,  if
commenced, may be discontinued at any time.

     The Trust Units may also be sold directly by the Trust at such prices and
upon such terms as agreed to by the Trust and the purchaser or through  agents
designated by the Trust from time to time.  Any agent involved in the offering
and sale of the Trust Units in respect of which this  Prospectus  is delivered
will be named, and any commissions  payable by the Trust to such agent will be
set forth, in the Prospectus  Supplement.  Unless  otherwise  indicated in the
Prospectus  Supplement,  any agent would be acting on a best efforts basis for
the period of its appointment.

     The Trust may agree to pay the  underwriters  a  commission  for  various
services relating to the issue and sale of any Trust Units offered hereby. Any
such  commission  will  be  paid  out  of the  general  funds  of  the  Trust.
Underwriters,  dealers and agents who  participate in the  distribution of the
Trust Units may be entitled under agreements to be entered into with the Trust
to  indemnification  by  the  Trust  against  certain  liabilities,  including
liabilities under securities  legislation,  or to contribution with respect to
payments which such underwriters, dealers or agents may be required to make in
respect thereof.

DISTRIBUTION POLICY

     Cash  distributions  to Unitholders are at the discretion of the board of
directors of PrimeWest and can fluctuate  depending on the cash flow generated
from  operations.  The cash flow available for  distribution is dependent upon
many factors,  including 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 and direct expenses of
the Trust,  as well as  reclamation  fund  contributions,  current  and future
capital expenditures and operating costs, debt service charges and general and
administrative expenses determined necessary by PrimeWest.  The Trust receives
monthly revenues pursuant to the Royalty in an amount determined,  in part, by
the  directors  of  PrimeWest,  as well as  income  from  other  sources,  and
distributes  a  portion  of  these  revenues  to  Unitholders   monthly.   See
"Description of the Royalty" above.

     Since August 2003,  the Trust has  followed a strategy of  maintaining  a
distribution  payout  ratio  within 70 - 90% of cash  flow,  calculated  on an
annual basis,  recognizing that, during periods of volatile  commodity prices,
the payout ratio may temporarily  move out of range. The board of directors of
PrimeWest   considers  a  variety  of  factors  in  establishing  the  monthly
distribution  level,  including,  but not limited to: commodity price outlook,
cash flow forecast, capital development plans, debt levels, tax considerations
and competitive industry distribution practices.  The Trust believes that this
strategy provides the Trust with greater financial  flexibility while reducing
the cost and potential dilution associated with financing activities.

                       CERTAIN INCOME TAX CONSIDERATIONS

     The  applicable  Prospectus  Supplement  will describe  certain  Canadian
federal income tax  consequences to an investor who is a resident of Canada or

distributions  relating  to the  Trust  Units  will  be  subject  to  Canadian
non-resident withholding tax.

     The applicable  Prospectus  Supplement will also describe  certain United
States federal income tax consequences of the ownership and disposition of any

                         INFORMATION NOT REQUIRED TO BE
                       DELIVERED TO OFFEREES OR PURCHASERS

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

         (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.

         (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.

                                     II-1


         (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.

         Section 5 of the bylaws of PrimeWest Energy Inc., the duly authorized
attorney of the Trust,  contains  the  following  provisions  with  respect to
indemnification of PrimeWest Energy Inc.'s directors and officers:

         5.01     Limitation of Liability. No director or officer for the time
being of the  Corporation  shall be liable  for acts,  receipts,  neglects  or
defaults of any other  director or officer or employee,  or for joining in any
receipt or act for conformity, or for any loss, damage or expense happening to
the  Corporation  through  the  insufficiency  or  deficiency  of title to any
property acquired by the Corporation or for or on behalf of the Corporation or
for the  insufficiency  of  deficiency of any security in or upon which any of
the moneys of or belonging to the Corporation shall be placed or invested,  or
for any loss or damage arising from the bankruptcy, insolvency or tortuous act
of any person,  firm or corporation  including any person, firm or corporation
with whom or with which any  moneys,  security  or effects  shall be lodged or
deposited, or for any loss, conversion,  misapplication or misappropriation of
or any damage resulting from any dealings with any moneys, securities or other
assets of or belonging  to the  Corporation  or for any other loss,  damage or
misfortune  whatsoever  which may happen in the execution of the duties of his
respective office or trust or in relation thereto unless the same shall happen
by or through his failure to exercise the powers and to  discharge  the duties
of his office honestly,  in good faith and with a view to the best interest of
the  Corporation  and  to  exercise  the  care,  diligence  and  skill  that a
reasonably prudent person would exercise in comparable circumstances.

         5.02     Indemnity.  The  Corporation  shall,  to the maximum  extent
permitted under the Act, indemnify a director or officer, a former director or
officer,  and 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 his heirs and legal representatives,  against all
costs, charges and expenses,  including any amount paid to settle an action or
satisfy a  judgment,  reasonably  incurred  by him in  respect  of any  civil,
criminal or administrative action or proceeding to which he is made a party by
reason of being or having  been a director  or officer of the  Corporation  or
such body corporate,  including (without  limitation) any such action by or on
behalf of the  Corporation or such body corporate to procure a judgment in its
favour,  and the  Corporation  shall use its reasonable best efforts to obtain
any approval or approvals necessary for such indemnification.

         Insofar  as  indemnification   for  liabilities   arising  under  the
Securities  Act of 1933 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.
