PrimeWest Energy Trust Announces First Quarter 2005 Results

    CALGARY, ALBERTA--(CCNMatthews - May 5, 2005) - PrimeWest Energy Trust 
(TSX:PWI.UN) (TSX:PWX) (TSX:PWI.DB.A) (TSX:PWI.DB.B) (NYSE:PWI) 
(PrimeWest or the Trust) today announced interim operating and financial 
results for the first quarter ended March 31, 2005. Unless otherwise 
noted, all figures contained in this report are in Canadian dollars.

FIRST QUARTER HIGHLIGHTS:

- Distributions of $0.90 per unit represented a payout ratio of 
approximately 80% of operating cash flow compared to fourth quarter 2004 
distributions of $0.90 per unit, representing a payout ratio of 76%.

- First quarter production averaged 40,616 barrels of oil equivalent 
(BOE) per day, compared to the fourth quarter 2004 rate of 44,368 BOE 
per day. The decrease in volumes is due to fourth quarter 2004 asset 
sales, temporary production constraints and natural decline. The 
decrease is partially offset by the incremental volumes from capital 
development activity.

- For the first quarter of 2005, a $60.0 million investment in 
development capital represents the highest quarterly development 
activity in PrimeWest's history. Twenty-nine (16.8 net) wells were 
drilled with a success rate of 86%.

- Incremental production volumes from development activity averaged 
approximately 950 BOE per day for the quarter. As a result of the 
capital program, 2,000 BOE per day remains behind pipe at quarter end, 
along with another 700 BOE per day that is shut-in due to regulatory and 
capacity constraints, resulting in a total of 2,700 BOE per day behind 
pipe.

- The Viking Energy Royalty Trust Units (Viking Trust Units), formerly 
Calpine Natural Gas Trust Units, were sold in February for net proceeds 
of $94.5 million, resulting in a gain of $26.9 million. These proceeds 
were used to repay debt and to fund capital expenditures.

- $40.3 million of Series I and Series II Convertible Subordinated 
Unsecured Debentures (Debentures) were converted into Trust Units of 
PrimeWest Energy Trust (Trust Units).

- Cash flow from operations was $79.7 million ($1.12 per unit) compared 
to $81.8 million ($1.15 per unit) in the fourth quarter of 2004.

- March 31, 2005 net debt to annualized first quarter 2005 cash flow was 
1.6 times compared to December 31, 2004 net debt to annualized fourth 
quarter cash flow of 1.7 times. PrimeWest has $307.7 million available 
on its existing borrowing base.

SUBSEQUENT EVENTS

- Subject to regulatory approval, the Board of Directors today approved 
offering the distribution reinvestment program (DRIP) to U.S. residents 
holding PrimeWest units. This will allow both U.S. residents and 
Canadian resident Unitholders the option of either reinvesting their 
monthly distributions in units of PrimeWest or continuing to receive 
cash payments. Previously only residents of Canada were eligible to 
participate in the DRIP. Details regarding the program's implementation 
will be released in the next few weeks.

(1) All calculations required to convert natural gas to a crude oil
    equivalent (BOE) have been made using a ratio of 6,000 cubic feet
    of natural gas to one barrel of crude oil. BOE's may be
    misleading, particularly if used in isolation. The BOE conversion
    ratio is based on an energy equivalency conversion method
    primarily applicable at the burner tip and does not represent a
    value equivalency at the wellhead.
(2) The basic per Trust Unit calculation includes the weighted
    average Trust Units and Trust Units issuable upon exchange of the
    Exchangeable Shares of PrimeWest Energy Inc.
    (Exchangeable Shares).
(3) The diluted per Trust Unit calculation includes the weighted
    average Trust Units, Trust Units issuable upon exchange of the
    Exchangeable Shares, the deemed conversion of the Debentures and
    Trust Units issuable pursuant to Long-Term Incentive Plan
    (LTIP). Interest expense incurred on the Debentures is added back
    to cash flow for the diluted per Trust Unit calculation.
(4) Interest expense includes the interest on the Debentures.
(5) Based on Trust Units outstanding at date of distribution.
(6) Net debt is long-term debt including Debentures less working
    capital, excluding financial derivative assets and liabilities.
(7) The net debt per Trust Unit calculation includes outstanding
    Trust Units, Trust Units issuable upon exchange of the
    outstanding Exchangeable Shares and Trust Units issuable pursuant
    to the LTIP at the end of the period.

Evaluation of Disclosure Controls and Procedures

The Chief Executive Officer, Don Garner, and Chief Financial Officer, 
Dennis Feuchuk, evaluated the effectiveness of PrimeWest's disclosure 
controls and procedures as of March 31, 2005 and concluded that 
PrimeWest's disclosure controls and procedures were effective to ensure 
that information PrimeWest is required to disclose in its filings with 
the Securities and Exchange Commission (SEC) under the Securities 
Exchange Act of 1934 (Exchange Act) is recorded, processed, summarized 
and reported, within the time periods specified in the SEC's rules and 
forms, and to ensure that information required to be disclosed by 
PrimeWest in the reports that it files under the Exchange Act is 
accumulated and communicated to PrimeWest's management, including its 
principal executive officer and principal financial officer, as 
appropriate to allow timely decisions regarding required disclosure.

Changes to Internal Controls and Procedures for Financial Reporting

There were no significant changes to PrimeWest's internal controls or in 
other factors that could significantly affect these controls subsequent 
to the evaluation date.

Non-GAAP Measures

The quarterly report contains the following measurements that are not 
defined by Canadian Generally Accepted Accounting Principles ("GAAP"):

- Cash flow from operations on a total and per Unit basis;

- Distributions per Trust Unit; and

- Net debt per Trust Unit.

These measurements do not have any standardized meaning prescribed by 
GAAP and are, therefore, unlikely to be comparable to similar measures 
presented by other entities.

Cash flow from operations is calculated from the Trust's cash flow 
statement as cash flow from operating activities before changes in 
working capital. Cash flow from operations per Trust Unit on a basic 
basis is calculated by dividing cash flow by the weighted average number 
of Trust Units and Trust Units issuable upon the exchange of 
Exchangeable Shares. Cash flow from operations per Trust Unit on a 
diluted basis is calculated using cash flow and adding back the interest 
expense on the Debentures, divided by the diluted weighted average 
number of Trust Units in the period. The diluted weighted average number 
of Trust Units consists of the weighted average Trust Units and Trust 
Units issuable upon the exchange of outstanding Exchangeable Shares and 
includes the Trust Units issuable pursuant to the conversion of the 
Debentures, and Trust Units issuable pursuant to the LTIP. Cash flow 
from operations is a key performance indicator of PrimeWest's ability to 
generate cash and finance operations and pay monthly distributions.

Distributions per Trust Unit disclose the cash distributions accrued in 
the first quarter of 2005 based on the number of Trust Units outstanding 
on the date the distributions were declared.

Net debt per Trust Unit is calculated as long-term debt, including 
Debentures, less working capital, excluding financial derivative assets 
and liabilities, divided by the number of Trust Units and Trust Units 
issuable upon the exchange of outstanding Exchangeable Shares and Trust 
Units issuable pursuant to the LTIP at March 31, 2005.

Critical Accounting Estimates

See pages 57 to 59 of the 2004 Annual Report for Discussion on Critical 
Accounting Estimates.

Vision, Core Business and Strategy

PrimeWest is a conventional oil and gas royalty trust actively managed 
to generate monthly cash distributions for Unitholders. The Trust's 
operations are focused in Canada, with its assets concentrated in the 
Western Canadian Sedimentary Basin. PrimeWest is one of North America's 
largest natural gas weighted energy trusts.

Maximizing total return to Unitholders, in the form of cash 
distributions and change in unit price, is PrimeWest's overriding 
objective. Our strategies for asset management and growth, financial 
management and corporate governance are outlined in this MD&A, along 
with a discussion of our performance in the first quarter of 2005 and 
our goals for the remainder of 2005 and beyond.

We believe that PrimeWest can maximize total return to Unitholders 
through the continued development of our core properties, making 
opportunistic acquisitions that emphasize value creation, exercising 
disciplined financial management which broadens access to capital while 
minimizing risk to Unitholders, and complying with strong corporate 
governance to protect the interests of all stakeholders.

Asset Management and Growth

PrimeWest has a strategy to focus our expansion efforts on existing 
Canadian core areas, and pursue depletion optimization strategies within 
those core areas to maximize asset value. We strive to control our 
operations whenever possible, and maintain high working interests. 
Maintaining control of 80% of operations allows us to use existing 
infrastructure and synergies within our core areas. We believe this high 
level of operatorship can translate into control over costs and timing 
of capital outlays and projects. The current size of the Trust gives us 
the ability and critical mass to make acquisitions of significant size, 
while still being able to add value by transacting smaller acquisitions.

Financial Management

PrimeWest strives to maintain a conservative debt position to allow us 
to fund smaller acquisitions without tapping into the capital markets, 
and to fund ongoing development activities. Our long-term debt is 
comprised of bank credit facilities through a bank syndicate, U.S. 
dollar denominated Senior Secured Notes (Secured Notes) and the 
Debentures. Our diversified debt instruments help to reduce our reliance 
on the bank syndicate, as well as afford additional foreign exchange 
protection because a portion of our debt, the Secured Notes, are 
denominated in US dollars. PrimeWest's commodity hedging approach helps 
to stabilize cash flow, reduce volatility, and protect acquisition 
economics.

PrimeWest continues to target a payout ratio between 70% and 90% of 
annual operating cash flow to increase the Trust's financial 
flexibility. The first quarter 2005 payout ratio was approximately 80% 
of operating cash flow. The retained cash flow was utilized to fund the 
Trust's capital spending program and repay debt. PrimeWest's net debt to 
cash flow level was 1.6 times at the end of the first quarter using 
annualized first quarter cash flows.

PrimeWest's dual listing on both the Toronto Stock Exchange (TSX) and 
New York Stock Exchange (NYSE) provide increased liquidity and a 
broadened investor base. The NYSE listing enables U.S. unitholders to 
conveniently trade in our Trust Units, and allows us to access the U.S. 
capital markets. Our status as a corporation for U.S. tax purposes 
simplifies tax reporting for our U.S. Unitholders.

For eligible Canadian unitholders, PrimeWest offers participation in the 
DRIP, which represents a convenient way to maximize an investment in 
PrimeWest. For alternate investment requirements, PrimeWest also has 
Exchangeable Shares and Debentures available, which permit participation 
in PrimeWest without the ongoing tax implications associated with 
receiving a distribution.

Corporate Governance

PrimeWest remains committed to the highest standards of corporate 
governance and upholds the rules of the governing regulatory bodies 
under which it operates. Full disclosure of our compliance with existing 
corporate governance rules and regulations is available on our website 
at www.primewestenergy.com. PrimeWest actively monitors the corporate 
governance and disclosure environment to ensure compliance with current 
and future requirements.

Our high standards of corporate governance are not limited to the 
boardroom. At the field level PrimeWest proactively manages 
environmental, health and safety issues. We place a great deal of 
importance on community involvement and maintaining good relationships 
with landowners.

Outlook - 2005

PrimeWest expects full year 2005 production volumes to average between 
40,000 - 41,000 BOE per day. Full year operating costs are expected to 
be approximately $6.60 per BOE. PrimeWest expects to invest $170 million 
in its capital development program, up from $125 million proposed in the 
February 24, 2005 news release, as a result of first quarter drilling 
success, increased land and seismic purchases, and to reflect higher 
third party costs for development activities.

The above table includes non-GAAP measurements. (Refer to discussion on 
Non-GAAP Measures on Page 5)

A key performance driver for the Trust is cash flow from operations, 
which directly affects PrimeWest's ability to pay monthly distributions. 
Cash flow is generated through the production and sale of crude oil, 
natural gas and natural gas liquids, and is dependent on production 
levels, commodity prices, operating expenses, interest expense, general 
and administrative (G&A), hedging gains or losses, royalties and 
currency exchange rates. Some of these factors such as commodity prices, 
the currency exchange rate and royalties are uncontrollable from 
PrimeWest's perspective. Other factors that are, to a certain extent, 
controllable by PrimeWest are production levels and operating expenses, 
as well as interest and G&A expenses.

The above table highlights PrimeWest's performance for the first quarter 
ended March 31, 2005, and the preceding seven quarters through 2004 and 
2003.

Net revenues are primarily impacted by commodity prices, production 
volumes and royalties.

Net income and net income per unit are secondary measures for a royalty 
trust because they include both cash and non-cash items. The non-cash 
items, which include depletion, depreciation and amortization (DD&A), 
non-cash G&A, future income taxes, unrealized foreign exchange gains or

/T/

During the first quarter of 2005, PrimeWest's net capital expenditures 
totalled $58.3 million, compared to $66.6 million invested in the first 
quarter of 2004 and ($36.7 million) in the previous quarter. Of the 
$60.0 million in development capital, $41.2 million or 69% was invested 
on drilling, completions and tie-ins that contribute to new reserve 
additions and help offset natural production decline. PrimeWest also 
invested $6.7 million on land acquisitions within core areas, acquiring 
approximately 30 sections for future development. The increasing costs 
for goods and services impacted capital expenditures; however, increases 
in commodity prices have offset these additional costs thereby 
maintaining project economics.

Gross wells drilled in the first quarter totalled 29 (16.8 net wells), 
with a success rate of approximately 86%. Capital development activity 
in the first quarter of 2005 was focused on PrimeWest's tight gas play 
in the areas of Caroline and Columbia. Twelve of the 29 wells drilled 
were in the tight gas play and up to an additional 10 wells are planned 
for the area during the remainder of 2005. The development capital 
expenditures resulted in incremental volumes averaging 950 BOE per day 
for the quarter and 2,000 BOE per day behind pipe at the end of the 
quarter.

Through acquisitions as well as development drilling, workovers, and 
recompletion activities, PrimeWest strives to offset natural production 
decline and add to reserves in order to sustain cash flows. Capital 
resources are allocated to projects on the basis of anticipated rate of 
return. At PrimeWest, every capital project is measured against 
stringent economic evaluation criteria prior to approval. These criteria 
include expected return, risks and further development opportunities.

Capital Outlook

PrimeWest has increased its full year capital program from $125 to $170 
million due to development opportunities in the first quarter. In 
addition, an aggressive land acquisition program along with higher third 
party costs for development activities have increased capital 
expenditures.

In the first quarter of 2005, $6.7 million was invested in land in core 
areas. Thirty sections of land were purchased, increasing PrimeWest's 
drilling inventory by 10 to 15 locations. Additional seismic and 
development results will be required to delineate the remaining sections.

The following describes the incremental amounts to be invested in the 
2005 capital program for each of the core areas.

- In our tight gas play (Caroline/Columbia), an additional 4 to 5 wells 
are planned in addition to land and seismic expenditures. In total an 
incremental $15.0 million will be invested on this play.

- In Edson, a five-well program is being advanced for an additional 
$12.0 million.

- In the Crossfield area our drilling program is being re-focused to 
higher working interest locations resulting in an additional $5.0 
million of capital investment. These wells require extensive planning 
and as such volumes are not forecast until year end.

- In Brant Farrow and on our coal bed methane lands an additional $6.0 
million will be expended for increased development and to test the 
feasibility of commercial development of coal bed methane on lands 
within the Horseshoe Canyon fairway located at Thorsby, Crossfield and 
Brant Farrow.

/T/

PrimeWest's production volumes averaged 40,616 BOE per day in the first 
quarter of 2005 compared to 44,368 BOE per day in the fourth quarter of 
2004. Production volumes decreased in the first quarter mainly due to 
fourth quarter 2004 asset sales representing a reduction of 
approximately 2,200 BOE per day. In addition, a third party pipeline 
failure and regulatory restrictions reduced production volumes by 400 
BOE per day and 200 BOE per day respectively with the remaining decrease 
due to natural decline.

The decrease in production volumes in the first quarter was partially 
offset by first quarter drilling, completion and tie-in activity which 
added incremental volumes averaging approximately 950 BOE per day for 
the quarter.

Approximately 2,700 BOE per day of production volumes remain behind pipe 
at the end of the first quarter 2005, which includes 2,000 BOE per day 
as a result of first quarter capital activity and 700 BOE per day that 
is shut-in due to regulatory and capacity constraints. Included in the 
volumes curtailed due to regulatory requirements is 500 BOE per day 
relating to the Cecil area.

Production Outlook

PrimeWest expects full year production volumes to average between 40,000 
- 41,000 BOE per day.

The shut-in volumes at Whiskey Creek area (400 BOE per day) are the 
result of limited capacity at the Quirk Creek gas plant. With no 
alternate facilities in the area, PrimeWest's production will remain 
behind pipe until processing capacity becomes available at the Quirk 
Creek facility which is expected to occur in the fourth quarter of 2005.

The production at Cecil (500 BOE per day) has been curtailed due to 
regulatory restrictions and will resume once the lands have been pooled 
and a waterflood has been initiated by the operator. PrimeWest is 
continuing to work with the operator to resolve the outstanding issues, 
with no volumes forecast for the
remainder of 2005.

A third party pipeline failure resulted in the temporary shut-in of 
volumes (400 BOE per day) in the Kaybob area. The pipeline has been 
repaired, however, a third party plant shutdown in April has further 
delayed restoring full production until the end of May 2005.

Canadian commodity prices were higher in the first quarter 2005 than 
during the same period in 2004 resulting in higher average realized 
selling prices per BOE.

Compared to the fourth quarter 2004, average realized sales prices per 
BOE increased marginally in the first quarter of 2005 due to higher 
crude oil and natural gas liquids prices offset by a lower average price 
for natural gas.

PrimeWest's cash flow from operations is directly impacted by commodity 
prices, but the use of hedging can increase or decrease the prices 
realized by the Trust. In the first quarter 2005, PrimeWest had a $5.4 
million hedging loss compared to a loss of $3.8 million for the same 
period in 2004.

/T/

First quarter 2005 revenues were 41% higher than the same period in 
2004, due to higher commodity prices and increased production volumes. 
Revenues are 9% lower in the first quarter of 2005 compared to the 
fourth quarter 2004 due to lower volumes offset by slightly higher 
realized prices.

PrimeWest derives approximately 72% of its revenues from natural gas; 
therefore, the Trust has greater sensitivity to changes in natural gas 
prices than crude oil prices.

Financial Derivatives

As part of our financial management strategy, PrimeWest uses a 
consistent commodity hedging approach. The purpose of the hedging 
program is to reduce volatility in cash flows, protect acquisition 
economics and to stabilize cash flow against the unpredictable commodity 
price environment. The hedging policy reflects a willingness to risk 
forfeiting a portion of the pricing upside in return for protection 
against a significant downturn in prices.

The following table sets forth the approximate percentage of future 
anticipated production volumes hedged at March 31, 2005, net of 
anticipated royalties, reflecting full production declines with no 
offsetting additions:

A 3-way option is like a traditional collar, except that PrimeWest has 
resold the put at a lower price. Utilizing the first 3-way natural gas 
contract above as an example, PrimeWest has sold a call at $9.92, 
purchased a put at $6.33, and resold the put at $5.28. Should the market 
price drop below $6.33, PrimeWest will receive $6.33 until the price is 
less than $5.28, at which time PrimeWest will then receive market price 
plus $1.05. However, should market prices rise above $9.92, PrimeWest 
will receive a maximum of $9.92. Should the market price remain between 
$6.33 and $9.92, PrimeWest will receive the market price.

PrimeWest's derivatives are mark-to-market at the end of each reporting 
period with the resulting gain or loss reflected in earnings for that 
period.

The first quarter 2005 income statement shows an unrealized loss of 
$35.2 million on derivatives resulting from the change in the 
mark-to-market valuation of the derivative financial instruments during 
the period. The loss was comprised of a $9.6 million loss for crude oil 
hedges; a $25.9 million loss for natural gas hedges and a $0.3 million 
gain for electrical power hedges.

For the period ended March 31, 2005 the cash impact of contract 
settlements was a $5.5 million loss comprised of a $5.5 million loss in 
crude oil, a $0.1 million gain in natural gas, and a $0.1 million loss 
on electrical power.

Royalties (Net of ARTC)

PrimeWest pays royalties to the owners of mineral rights with whom 
PrimeWest holds leases. PrimeWest has mineral leases with the Crown 
(Provincial and Federal Governments), freeholders (individuals or other 
companies) and other operators. ARTC is the Alberta Royalty Tax Credit, 
a tax rebate provided by the Alberta government to producers that paid 
eligible Crown royalties in the year.

/T/

Royalty expense in the first quarter of 2005 was approximately 54% 
higher than the same quarter in the previous year due to higher 
revenues. First quarter 2005 royalty expense is 13% lower than the 
fourth quarter of 2004 due to lower revenues which are partially 
attributable to the volume decrease resulting from the fourth quarter 
2004 asset sales.

The Crown royalty system is based on a sliding scale structure that 
increases the royalty rates as commodity prices rise. Because of the 
sliding scale, future changes to commodity prices will result in changes 
in royalty rates and expenses.

/T/

The first quarter 2005 operating expenses are 14% lower than the 
previous quarter due to fourth quarter 2004 asset sales and a lower 
short-term incentive bonus accrual. The operating expenses are higher 
than the first quarter of 2004 due to increased production volumes 
resulting from 2004 acquisitions. On a per BOE basis operating costs for 
the first quarter of 2005 are lower than the same period in 2004 due to 
the impact of the Calpine assets acquired in 2004 which have a lower 
operating cost per BOE.

Operating Expenses Outlook

General industry inflation is expected to increase overall field 
operating expenses in 2005. PrimeWest expects 2005 operating expenses to 
average approximately $6.60 per BOE which is 3% lower than 2004, 
reflecting the impact of the Calpine acquisition and the asset 
divestment program.

/T/

Operating margin per BOE increased 9% in the first quarter of 2005 
compared to the same quarter in 2004. This is primarily due to higher 
sales prices and production volumes and lower operating expenses offset 
by higher royalties. Operating margin is an important measure of our 
business because it gives an indication of the amount of cash flow 
PrimeWest realizes per BOE that is produced, before head office expenses 
and financing charges.

Operating margin is higher in the first quarter 2005 compared to the 
fourth quarter 2004, primarily as a result of higher sales prices, lower 
operating expenses and lower royalties.

The operating margin for 2005 will be heavily dependent on commodity 
prices. PrimeWest will continue to pursue a strategy to maintain lower 
than average operating expenses to maximize margins, which can help to 
reduce the volatility of cash flows through commodity price cycles.

---------------------------------------------------------------------

/T/

Cash G&A expense in the first quarter of 2005 decreased from the 
previous quarter due to lower short-term incentive bonuses and higher 
overhead recoveries, offset by increases to salaries and benefits, 
annual report costs and regulatory fees.

Expenses related to the Long Term Incentive Plan ("LTIP") are recorded 
on a mark-to-market basis, whereby increases or decreases in the 
valuation of the UAR liability are reflected in the income statement. 
Included in the first quarter non-cash G&A expense is $14.7 million 
relating to the change in the value of the Unit Appreciation Rights 
(UARs) issued under the LTIP. UARs in a trust are similar to stock 
options in a corporation. The LTIP program is based on total Unitholder 
return, which is comprised of cumulative distributions on a reinvested 
basis plus growth in unit price. No benefit accrues to the UARs until 
the Unitholders have first achieved a 5% total annual return from the 
time of the UAR grant. PrimeWest continues to pay for the exercise of 
UARs in Trust Units.

PrimeWest's non-cash G&A expenses (on a total and per BOE basis) 
increased in the first quarter of 2005 compared to the previous quarter. 
The increase is due to the change in the value of the UARs resulting 
from an increase in the Trust Unit price to $28.99 at March 31, 2005 
from $26.62 at December 31, 2004.

G&A Expense Outlook

Cash G&A expenses in 2005 are expected to be lower than in 2004 and are 
expected to be approximately $1.25 per BOE for the year.

/T/

Interest expense, representing interest on bank debt, the Secured Notes 
and the Debentures decreased in the first quarter of 2005 compared to 
the fourth quarter of 2004, due to a lower net debt balance.

The increase in interest expense in the first quarter 2005 compared to 
the same period in 2004 is due to the issuance of the Debentures to 
finance the acquisition of Calpine oil and gas assets in the third 
quarter of 2004.

The decrease in the net debt level at March 31, 2005 compared to the 
prior quarter is due to the reduction in the bank debt and to the 
conversion of $39.1 million of the Debentures during the first quarter.

The increase in the average cost of debt in the first quarter is due to 
the impact of the issuance of Series I and Series II Debentures which 
bear interest at 7.5% and 7.75% respectively.

Foreign Exchange

The foreign exchange loss of $0.9 million for the three months ended 
March 31, 2005 results from the translation of the U.S. dollar 
denominated Secured Notes and related interest payable into Canadian 
dollars.

Site Reclamation and Restoration Reserve

Since the inception of the Trust, PrimeWest has maintained a site 
reclamation fund to pay for future costs related to well abandonment and 
site clean up. The fund is used to pay for such costs as they are 
incurred. The 2005 contribution rate for the fund is unchanged from 2004 
at $0.50 per BOE. As at March 31, 2005, the site reclamation fund 
contained a balance of $11.3 million.

The abandonment and reclamation costs incurred in the first quarter 2005 
were $0.9 million, compared to $0.9 million for the same period in 2004,

Cash flow from operations, as opposed to net income, is the primary 
measure of performance for an energy trust. The generation of cash flow 
is critical for an energy trust to continue paying its distributions to 
unitholders.

Conversely, net income is an accounting measure impacted by both cash 
and non-cash items. The largest non-cash items impacting PrimeWest's net 
income are DD&A, the unrealized loss on derivatives, future taxes and 
non-cash G&A.

First quarter 2005 net income was lower than the previous quarter due to 
lower net oil and gas revenues, increases in non-cash G&A expenses and 
unrealized losses on derivatives offset by higher future income tax 
recoveries.

being attributed to the Secured Notes valued at $162.5 million based on 
the U.S. dollar exchange rate at the time of the last renewal in 2004. 
In addition to amounts outstanding under the facility, PrimeWest has 
outstanding letters of credit in the amount of $4.8 million (2004 - $4.8 
million). The credit facility revolves until June 30, 2005, by which 
time the lenders will have conducted their annual borrowing base review.

PrimeWest's first quarter 2005 net debt of $516.1 was lower than 
December 31, 2004 net debt of $552.0 million mainly due to the 
conversion of $39.1 million of the Debentures. The sale of the Viking 
Trust Units resulted in cash proceeds of $21.8 million in excess of 
their initial cost. The cash was used to reduce the credit facility and 
to fund the capital program in the first quarter.

At March 31, 2005 PrimeWest's net debt to annualized first quarter cash 
flow was approximately 1.6 times compared to 1.7 times at December 31, 
2004. Net debt as a percentage of total capitalization was 20% at March 
31, 2005, compared to 23% at December 31, 2004.

In accordance with CICA Handbook Section 3860 - "Financial Instruments" 
Series I and Series II Debentures were initially recorded in long-term 
debt at their fair value of $147.0 million and $94.9 million 
respectively. The difference between the fair value and proceeds was 
recorded in unitholders' equity.

The Series I and Series II Debentures are being accreted such that the 
liability at maturity will equal the initial proceeds of $150 and $100 
million less conversions, respectively.

During the first quarter of 2005, $26.5 million of the Series I and 
$12.6 million of the Series II Debentures long-term debt component were 
converted to Trust Units. Accretion of $0.2 million was realized on each 
of the Series I and Series II Debentures.

Unitholders' Equity

At April 30, 2005, the Trust had 72,427,230 Trust Units outstanding. In 
addition, PrimeWest had 1,224,049 Exchangeable Shares outstanding that 
are exchangeable into a total of 642,503 Trust Units using the April 15, 
2005 exchange ratio of 0.52490:1.

The Series I and Series II Debentures equity components have been 
reduced by $0.5 million and $0.7 million respectively due to conversions 
to Trust Units in the quarter.

For Canadian resident unitholders, PrimeWest offers the DRIP. Components 
of the DRIP include the Optional Trust Unit Purchase Plan (OTUPP) and 
the Premium Distribution Plan (PREP). The DRIP gives Canadian 
Unitholders the chance to reinvest their monthly distributions at a 5% 
discount to the volume weighted average market price, while the OTUPP 
gives Canadian Unitholders an opportunity to purchase additional Trust 
Units directly from PrimeWest at the same 5% discount to the volume 
weighted average market price. The PREP allows eligible Canadian 
unitholders to elect to receive a premium cash distribution of up to 
102% of the cash that the unitholder would otherwise have received on 
the distribution date, subject to proration in certain events. The DRIP 
and PREP components are mutually exclusive. Participation in the OTUPP 
requires enrolment in either the DRIP or the PREP. Subject to regulatory 
approval, PrimeWest will be offering the DRIP to U.S. residents holding 
PrimeWest units in the near future.

During the quarter, PrimeWest issued 65,052 Trust Units for $1.8 million 
under
the DRIP, 291,695 Trust Units for $7.9 million pursuant to the PREP and 
276,313 Trust Units for proceeds of $7.6 million from the OTUPP.

For further details on these plans or to obtain the enrolment forms, 
please contact PrimeWest's Plan Agent, Computershare Trust Company of 
Canada at 1-800-564-6253, or visit PrimeWest's website at 
www.primewestenergy.com.

These plan components benefit Unitholders by offering alternatives to 
maximize their investment in PrimeWest while providing the Trust with an 
inexpensive method to raise additional capital. Proceeds from these 
plans are used for debt reduction and to help fund ongoing capital 
development programs.

Exchangeable Shares

Exchangeable Shares were issued in connection with both the Venator 
Petroleum Company Ltd. acquisition in April 2000 and the Cypress Energy 
Inc. acquisition in March 2001. These shares were issued to provide a 
tax-deferred rollover of the adjusted cost base from the shares being 
exchanged to the Exchangeable Shares. Canadian tax law does not permit a 
tax deferral when shares are exchanged for Trust Units.

The Exchangeable Shares do not receive cash distributions. In lieu of 
receiving distributions, the number of Trust Units that the exchangeable 
shareholder will receive upon exchange increases each month based on the 
distribution amount divided by the market price of the Trust Units on 
the 15th day of that month.

At March 15, 2005, there were 1,226,049 Exchangeable Shares outstanding. 
The exchange ratio on these shares was 0.51956:1 Trust Units for each 
Exchangeable Share as at the end of the first quarter. For purposes of 
calculating basic per Trust Unit amounts, the assumption is that these 
Exchangeable Shares are exchanged into Trust Units at the current 
exchange ratio.

Cash Distributions

Cash distributions to Unitholders are at the discretion of the Board of 
Directors and can fluctuate depending on the cash flow generated from 
operations. As discussed previously, the cash flow available for 
distribution is dependent upon many factors including commodity prices, 
production levels, debt levels, capital spending requirements, and 
factors in the overall industry environment. In order to increase 
PrimeWest's financial flexibility, the Board of Directors maintains a 
longer-term target distribution payout ratio of approximately 70% to 90% 
of cash flow from operations.

In the first quarter of 2005, cash distributions totalled $63.8 million, 
or $0.90 per Trust Unit representing a payout ratio of approximately 
80%, compared to $41.1 million, or $0.82 per Trust Unit (70% payout 
ratio) for the same period in 2004. In the fourth quarter 2004 cash 
distributions totalled $62.6 million, or $0.90 per Trust Unit 
representing a payout ratio of approximately 76%.

Distribution payments to U.S. Unitholders are subject to a 15% Canadian 
withholding tax, which is deducted from the entire distribution amount 
prior to deposit into accounts.

Contractual Obligations

PrimeWest enters into many contractual obligations as part of conducting 
day-to-day business. Material contractual obligations include debt 
obligations, lease rental commitments that run from 2005 through 2009 
and various pipeline transportation commitments that run through 2010. 
The details of the timing of these contractual obligations are included 
in the following table.

As part of PrimeWest's internalization transaction (see Note 14 in the 
Consolidated Financial Statements of the 2004 Annual Report), PrimeWest 
agreed to issue 377,360 Exchangeable Shares to the Executive Officers 
pursuant to a Special Employee Retention Plan. One quarter (94,340 
shares) of the Exchangeable Shares were issued to the Officers on 
November 6, 2004. One third of the remaining Exchangeable Shares will be 
issued on each of third, fourth and fifth anniversaries of the 
transaction closing, November 6, 2002. As at March 31, 2005, $0.4 
million has been accrued in non-cash G&A expenses related to the Special 
Employee Retention Plan.

Business Risks

PrimeWest's operations are affected by a number of underlying risks, 
both internal and external to the Trust. These risks are similar to 
those affecting others in both the conventional oil and gas royalty 
trust sector and the conventional oil and gas producers sector. The 
Trust's financial position, results of operations, and cash available 
for distribution to Unitholders are directly impacted by these factors. 
These factors are discussed under two broad categories - "Commodity 
Price, Foreign Exchange and Interest Rate Risk", and "Operational and 
Other Business Risks."

Commodity Price, Foreign Exchange And Interest Rate Risk

The two most important factors affecting the level of cash distributions 
available to unitholders are the level of production achieved by 
PrimeWest, and the price received for its products. These prices are 
influenced in varying degrees by factors outside the Trust's control. 
Some of these factors include:

- World market forces, specifically the actions of OPEC and other large 
crude oil producing countries including Russia, and their implications 
on the supply of crude oil;

- World and North American economic conditions which influence the 
demand for both crude oil and natural gas and the level of interest 
rates set by the governments of Canada and the U.S.;

- Weather conditions that influence the demand for natural gas and 
heating oil;

- The Canadian/U.S. dollar exchange rate that affects the price received 
for crude oil as the price of crude oil is referenced in U.S. dollars;

- Transportation availability and costs; and

- Price differentials among World and North American markets based on 
transportation costs to major markets and quality of production.

To mitigate these risks, PrimeWest has an active hedging program in 
place based on an established set of criteria that has been approved by 
the Board of Directors. The results of the hedging program are reviewed 
against these criteria and the results actively monitored by the Board.

Beyond our hedging strategy, PrimeWest also mitigates risk by having a 
well-diversified marketing portfolio and by transacting with a number of 
counterparties and limiting exposure to each counterparty. For the first 
quarter of 2005 approximately 25% of natural gas production was sold to 
aggregators and 75% of production was sold into the Alberta short-term 
or export long-term markets.

The contracts that PrimeWest has with aggregators vary in length. They 
represent a blend of domestic and US markets and fixed and floating 
prices designed to provide price diversification to our revenue stream.

The primary objective of our commodity risk management program is to 
reduce the volatility of our cash distributions, to lock in the 
economics on major acquisitions and to protect our capital structure 
when commodity prices cycle downwards. In the first quarter 2005, 
PrimeWest lost $5.4 million from commodity hedges.

Operational And Other Business Risks

PrimeWest is also exposed to a number of risks related to its activities 
within the oil and gas industry that have an impact on the amount of 
cash available to Unitholders. These risks, and the manner in which 
PrimeWest seeks to mitigate these risks include, but are not limited to:

Notes to Consolidated Financial Statements

For the three months ended March 31, 2005, (except per Trust unit 
amounts) all amounts are expressed in millions of Canadian dollars 
unless otherwise indicated.

1. Significant Accounting Policies

These interim consolidated financial statements of PrimeWest have been 
prepared in accordance with Canadian generally accepted accounting 
principles. The specific accounting principles used are described in the 
annual consolidated financial statements of the Trust appearing on pages 
70 through 72 of the Trust's 2004 annual report and should be read in 
conjunction with these interim financial statements.

2. Marketable Securities

Investment in Viking Trust
 (formerly Calpine Natural Gas Trust)           $    -     $    68.6
---------------------------------------------------------------------
---------------------------------------------------------------------

/T/

PrimeWest sold its 8% interest in the Viking Energy Royalty Trust for 
net proceeds of $94.5 million. The investment was accounted for using 
the cost method. The sale resulted in a gain of $26.9 million.

3. Asset Retirement Obligations

Management has estimated the total future asset retirement obligation 
based on the Trust's net ownership interest in all wells and facilities. 
This includes all estimated costs to dismantle, remove, reclaim and 
abandon the wells and facilities and the estimated time period during 
which these costs will be incurred in the future.

The following table reconciles the asset retirement obligation 
associated with the retirement of oil and gas properties:

---------------------------------------------------------------------
Asset Retirement Obligation, March 31, 2005                 $   34.8
---------------------------------------------------------------------
---------------------------------------------------------------------

/T/

As at March 31, 2005, the undiscounted amount of estimated cash flows 
required to settle the obligation is $217.9 million. The estimated cash 
flow has been discounted using a credit-adjusted risk free rate of 7.0 
percent and an inflation rate of 1.5 percent. Although the expected 
period until settlement ranges from a minimum of 1 year to a maximum of 
50 years, the expectation is that costs will be paid over an average of 
34 years. These future asset retirement costs will be funded from the 
cash reserved for site restoration and reclamation. This cash reserve is 
currently funded at $0.50 per BOE from PrimeWest's operating resources.

/T/

The weighted average number of Trust Units and Exchangeable Shares 
outstanding for the three months ended March 31, 2005 was 71,239,168 
(2004 - 50,483,218). For purposes of calculating diluted net income per 
Trust Unit for the three months ended March 31, 2005, 5,432,754 (2004 - 
0) and 3,677,367 (2004 - 0) Trust units issuable pursuant to the 
conversion of the Convertible Unsecured Subordinated Debentures Series I 
and II respectively and 699,737 Trust Units (2004 - 335,341) issuable 
pursuant to the Long-Term Incentive Plan were added to the weighted 
average number.

Exchangeable Shares

The Exchangeable Shares are exchangeable into Trust Units at any time up 
to March 29, 2010 based on an exchange ratio that adjusts each time the 
Trust makes a distribution to its Unitholders. The exchange ratio, which 
was 1:1 on the date that the Exchangeable Shares were first issued, is 
based on the total monthly distribution, divided by the closing unit 
price on the distribution payment date. The exchange ratio effective 
March 15, 2005 was 0.51956:1.

6. Long-Term Incentive Plan

Under the terms of the Long-Term Incentive Plan, a maximum of 1,800,000 
Trust Units are reserved for issuance pursuant to the exercise of Unit 
Appreciation Rights (UARs) granted to Directors and employees of 
PrimeWest. Payouts under the plan are based on total unitholder return, 
calculated using both the change in the Trust Unit price as well as 
cumulative distributions paid. The plan requires that a hurdle return of 
5% per annum be achieved before payouts accrue. UARs have a term of up 
to six years and vest equally over a three-year period, except for those 
issued to the members of the Board, which vest immediately. The Board of 
Directors has the option of settling payouts under the plan in PrimeWest 
Trust Units or in cash. To date, all payouts under the plan have been in 
the form of Trust Units.
