Item 3.      Source and Amount of Funds or Other Consideration.
             -------------------------------------------------

     Each of the reporting persons named in Item 2 initially acquired the shares
of Common Stock as a result of the merger (the  "Merger")  of KOG  Acquisitions,
Inc., a Colorado corporation and wholly-owned  subsidiary of the Company ("Sub")
with and into Hallador Exploration Company, an Oklahoma corporation ("HEC"). The
Merger,  effective  September 19, 1989,  caused each outstanding share of Common
Stock of HEC to be converted  into the right to receive  11.39 shares of Company
Common Stock, and up to 1.66 additional shares of Company Stock,  dependent upon
the results of a revaluation of Hallador  Drilling  Program 1987-A.  Each of the
reporting persons was a shareholder of HEC.

     Prior  to  disclaiming  beneficial  ownership  of  the  Common  Stock,  the
reporting  persons  acquired  additional  shares of Common Stock  through use of
their personal funds and conversion of the Company's  debentures.  The reporting
person did not acquire the Common Stock with borrowed funds.

Item 4.  Purpose of the Transactions.
         ---------------------------

     The  purpose  of the Merger  was to expand  and  diversify  the oil and gas
reserve base and to increase the operating  capabilities of HEC. The acquisition
of Common Stock after the merger was for investment purposes only.

     On March 15, 2002, the reporting  persons  assigned all of their beneficial
ownership  interest to Messrs.  David C. Hardie and Steven Hardie pursuant to an
Amended and Restated Assignment and Nominee Agreement ("Agreement"). The purpose
of the Agreement was to consolidate the voting and dispositive  control over the
Common  Stock  amongst the various  Hardie  family  members to Messrs.  David C.
Hardie and Steven Hardie.  Please see Mr. David C. Hardie's  Schedule 13D filing
filed on March 15, 2002 for additional information.

     The reporting persons have no current plans or proposals which relate to or
would  result  in  any  of  the  following:   (i)  an  extraordinary   corporate
transaction,  such as a merger,  reorganization  or  liquidation,  involving the
Company or any of its subsidiaries; (ii) a sale or transfer of a material amount
of assets of the  Company  or any of its  subsidiaries;  (iii) any change in the
present board of directors or management of the Company,  including any plans or
proposals  to change the  number or term of  directors  or to fill any  existing
vacancies on the board;  (iv) any material change in the present  capitalization
or dividend  policy of Company;  (v) any other material  change in the Company's
business or corporate structure;  (vi) changes in the Company's charter,  bylaws
or  instruments  corresponding  thereto  or other  actions  which may impede the
acquisition  of control of  AremisSoft  by any person;  (vii) causing a class of
securities of the Company to be delisted from a national  securities exchange or
to cease to be authorized to be quoted in an inter-dealer  quotation system of a
registered national securities association;  (viii) a class of equity securities
of the Company  becoming  eligible for termination of  registration  pursuant to
Section  12(g)(4)  of the  Act;  or (ix)  any  action  similar  to any of  those
enumerated above.
