1.  The interim financial data is unaudited; however, in our opinion, it
    includes all adjustments, consisting only of normal recurring adjustments
    necessary for a fair statement of the results for the interim periods.
    The financial statements included herein have been prepared pursuant 
    to the SEC's rules and regulations; accordingly, certain information 
    and footnote disclosures normally included in GAAP financial statements
    have been condensed or omitted.

2.  Our organization and business, the accounting policies we follow and 
    other information are contained in the notes to our financial statements
    filed as part of our 2004 Form 10-KSB.  This quarterly report should be
    read in conjunction with that annual report. 
 

3.  On April 15, 2005, we issued 750,000 ten-year options to employees at an
    exercise price of $2.25.  The exercise price was based on the sales 
    price of a March 2005 private stock transaction beween one of our 
    shareholders and a third party.  These options vest at 1/3 per year
    over the next three years.  There are no more options available for
    issuance.

    As allowed in SFAS 123, Accounting for Stock-Based Compensation, we 
    continue to apply APB 25, Accounting for Stock Issued to Employees, 
    and related interpretations in recording compensation related to our
    plan.  Had compensation costs for the plan been determined consistent
    with SFAS 123, we would have estimated the fair value of the option 
    grant using the Black-Scholes option-pricing model, using the following
    assumptions for the 2005 grants: (i) risk free interest rate of 4.24%; 
    (ii) expected life of 10 years; (iii) expected volatility of 120%; and 
    (iv) no dividend yield.  The average fair value of options granted
    during 2005 was $2.15.  Pro forma net loss for the three and nine month
    periods ended September 30, 2005 would have been $241,000 and $200,000
    or $(0.03) per share, respectively.  Pro forma results for 2004 were
    immaterial.

4.  On August 10, 2004, Hallador Petroleum LLP (the "Partnership") entered
    into an agreement with E&B Natural Resources Management Corporation (a
    private company) to sell all of our interest in the South Cuyama field
    and adjacent exploration areas, all located in Santa Barbara County,
    California, for $23 million; consisting of $19.5 million in cash and
    an interest bearing (3.5%) note of $3.5 million due on September 30,
    2005 which has since been paid.  Closing occurred on September 30, 2004
    and we recorded a pre-tax gain of about $14 million.  Results from the 
    South Cuyama field have been presented as discontinued operations in  
    the accompanying Consolidated Statement of Operations.  Revenue and
    expenses before the minority interest were about $7 million and 
    $5 million, respectively for the nine months ended September 30, 2004.

    Due to the sale, the joint board of directors of Hallador Petroleum
    Company and the Executive Committee of the Partnership, voted to 
    discontinue new partnership operations effective October 1, 2004.
    On May 6, 2005 we made a cash distribution of about $5.2 million to
    the limited partners.  During the third quarter 2005, Hallador 
    Petroleum Company purchased the limited partners interest in the
    Partnership for about $1.2 million and made a final cash distribution
    to the limited partners of $1.6 million.  After the cash payments to 
    the limited partners, about $1.7 million remained in the minority
    interest account and was recorded as a reduction in our accumulated
    deficit account.  For accounting purposes the Partnership no longer
    exists, and as a result, there is no longer a minority interest caption
    on our balance sheet.

    Upon filing the Federal and State returns in September for December 31,
    2004, we determined that we under estimated the taxes due on the sale 
    by about $116,000 and accrued for such in the third quarter of 2005.
 

5.  In late March 2005, we invested $325,000 for a 29% interest in a newly 
    formed entity called COALition Energy, LLC (CELLC).  CELLC was formed to
    pursue coal investments.  To date CELLC has not commenced significant
    operations.  We account for this investment using the equity method of
    accounting.

    Four of our directors, David Hardie, Steven Hardie, Cortlandt Dietler,
    and Victor Stabio, who is also our CEO and CFO, acquired, at the same 
    proportionate cost, and on the same terms as us, membership interests 
    of 3.09%, 3.09%, 4.64%, and 3.09%, respectively, based on personal
    investments of $33,333, $33,333, $50,000 and $33,334, respectively, 
    in CELLC.  Some of our directors are also directors of CELLC.  An 
    affiliate of Yorktown Energy Partners II, acquired a 20% interest in
    CELLC for about $225,000.  Yorktown Energy Partners II., L.P. owns 
    about 32% of our common stock.

6.  In late August 2005, we were sued for about $2.1 million by an employee
    of one of our vendors.  The employee was injured in an accident in 2003
    and did not file a lawsuit against us until 2005.  We have discussed the
    matter with our insurance company and our maximum exposure is about
    $100,000.


                           HALLADOR PETROLEUM COMPANY
          Management's Discussion and Analysis of Plan of Operation

RESULTS OF OPERATIONS
---------------------

Overview
--------

The following discussion updates the MD&A section of our 2004 Form 10-KSB 
which was filed on April 15, 2005 and should be read in conjunction thereto.

     Potential Acquisition
     ---------------------

We are in negotiations whereby we would issue 1,893,000 shares of our 
common stock valued at $2.20 per share to Yorktown Energy Partners VI., 
L.P.  The proceeds of this stock sale will be used to purchase a 32% 
interest in a private Michigan oil and gas exploration company from 
Yorktown Energy Partners II, L.P.   Yorktown Energy Partners II, L.P.
owns about 32% of our common stock. 
 
     Albany Shale Gas Lease Play
     ---------------------------

Since June 30, 2005 we have invested about $2.7 million in this wildcat gas
play located in Western Kentucky, of which $586,000 was after September 30,
2005 .  To date we have leased about 61,000 acres.  Over 80% of the acreage
is held under five-year leases with the right to extend for another five years
by paying $2 per acre per year.  We hope to sell the unproved acreage and
retain some sort of interest.

     Montana
     -------

We are evaluating two lease plays in central Montana.  To date no funds
have been committed.

     North Dakota
     ------------ 

As disclosed in the 2004 Form 10-KSB, in February 2005 we invested $1.3 
million in a 2,500 acre oil development prospect in McKenzie County, North
Dakota, located on the mid-western Montana border.  On April 25, 2005 we
purchased additional acres for $111,000.  On October 12, 2005, we purchased
additional acreage for $195,000.  We have a 37.5% WI (.328 NRI), Kodiak Oil
and Gas, the operator also has a 37.5% WI, the remaining 25% is owned by
others. Kodiak is headquartered in Denver and its stock trades on the TSX 
Venture Exchange under the symbol KOG.  We hope to drill the first oil well
the first half of 2006, at a cost of about $2.5 million to the 100%.  This 
is a horizontal play so a vertical well is drilled to 8,000 feet and then
two horizontal laterals are drilled at distance of 4,000 - 6,000 feet in
opposite directions.  Headington Oil Company is a major operator in this
area on the Montana side and Burlington Resources is a major operator on
the North Dakota side.  Depending on the success of the first well, our 
total commitment could be an additional $2 million to the 100%.

     San Juan Basin
     --------------

Two more development gas wells were drilled in September 2005 and are 
awaiting completion.  Due to the shortage of manpower and equipment these 
wells will not be placed on production until mid November 2005.  The costs 
were about $1 million each to the 100% and we have a .056 WI (.047 NRI) in 
each of these wells.

     Coal 
     ----

As disclosed in the 2004 Form 10-KSB, in late March 2005, we invested $325,000
for a 29% interest in a newly formed entity called COALition Energy, LLC
(CELLC).  To date, CELLC has not commenced significant operations.  Some of
our directors and officers also invested in CELLC.   See Note 5 to the
Financial Statements for further information.

Liquidity and Capital Resources 
------------------------------- 

Cash and cash to be provided from operations are expected to enable us to meet 
our obligations as they become due during the next several years. 

We have no bank debt, no special purpose entities and no off-balance sheet
arrangements.

Litigation
----------

In late August 2005, we were sued for about $2.1 million by an employee of
one of our vendors.  The employee was injured in an accident in 2003 and 
did not file a lawsuit against us until 2005.  We have discussed the matter 
with our insurance company and our maximum exposure is about $100,000.

Revenue increased due to higher prices.  The higher prices more than offset
the decline in production as indicated above. San Juan natural gas is sold
at an index price that is set at the first of every month and remains in 
effect for the entire month.  Our San Juan November 2005 gas price is about
$11.52 per MCF.  During the first ten days of November, daily posted San Juan 
gas prices have fallen to $7.52 per MCF.  If prices stay at this level, our
December price could be about $4 per MCF less than our November price.

Interest income increased due to investing the proceeds from the sale that
occurred in September 2004 and interest income earned on the $3.5
million note due September 30, 2005 which was paid.

During the third quarter, we decided to impair our investments in certain
Wyoming lease plays.

General and administrative expenses declined due to the termination of
two employees after the California property sale, and salary reductions 
in the Denver office.  Victor P. Stabio's salary was reduced 26% and
certain other employees' salaries were reduced 10%.

Upon filing the Federal and State returns in September for December 31, 2004,
we determined that we under estimated the taxes due on the sale by
about $116,000 and accrued for such in the third quarter of 2005.

ITEM 3. CONTROLS AND PROCEDURES

We maintain a system of disclosure controls and procedures that are designed
for the purposes of ensuring that information required to be disclosed in our
SEC reports is recorded, processed, summarized and reported within the time
periods specified in the SEC's rules and forms, and that such information is
accumulated and communicated to our CEO as appropriate to allow timely
decisions regarding required disclosure.

As of the end of the period covered by this report, we carried out an 
evaluation, under the supervision and with the participation of our CEO of 
the effectiveness of the design and operation of our disclosure controls and
procedures. Based upon that evaluation, our CEO, who is also our CFO, 
concluded that our disclosure controls and procedures are effective for the
purposes discussed above. There have been no changes in our internal controls
or in other factors that could significantly affect these controls subsequent
to the date of the evaluation.
