the  persons  listed in  Schedule A hereto (the  "Stockholders").  The  Company,
Pannonian  and San Joaquin are  collectively  referred to herein as the "Company
Parties." Brek, Brek Petroleum and the Stockholders are collectively referred to
herein as the  "Purchasers."  The Company,  Pannonian,  San Joaquin,  Brek, Brek
Petroleum  and the  Stockholders  are  collectively  referred  to  herein as the
"Parties" and, individually, each a "Party".

                              W I T N E S S E T H:

     WHEREAS, Brek owns 500 shares of Series A Convertible  Redeemable Preferred
Stock, $.001 par value, of the Company  ("Preferred Stock") and 4,750,000 shares
of common stock,  $.0001 par value,  of the Company  ("Common  Stock") (all such

     WHEREAS,  the Stockholders  collectively own a total of 1,500,000 shares of

     WHEREAS,  the Purchasers  desire to purchase from the Company Parties,  and

in all  undeveloped  oil and gas  leases  and  rights to  acquire  interests  in
undeveloped  oil and gas leases held by the Company  Parties at the date of this
Agreement  in exchange  for all of the Brek Shares and the  Stockholder  Shares,
having an  aggregate  agreed fair market value of  $22,000,000  (all such shares
being collectively referred to herein as the "Shares") plus an option to acquire
up to an additional 5% undivided interest in such properties for $10,500,000.

     NOW,  THEREFORE,  in  consideration  of the  foregoing  and the  respective
representations,  warranties,  covenants and  agreements  set forth herein,  the
parties hereto agree as follows:

ARTICLE I

                              THE SALE AND PURCHASE

Section  1.01 Sale and  Purchase of Initial  Interest.  At the Closing  (defined
below),  subject to the terms and  conditions of this  Agreement and in reliance
upon the  representations  and warranties  contained herein, the Company Parties
will sell,  transfer  and  deliver to the  Purchasers  and the  Purchasers  will
purchase from the Company Parties:

(i) an initial  undivided 25% of the Company Parties' right,  title and interest
in all of the oil and gas  leases  owned by the  Company  Parties at the date of
this Agreement (except for Developed Properties and the Special Phillips Leases,
as defined  below),  which oil and gas leases are  identified  in Exhibit A, but
only  insofar as such leases cover the lands that are not  Developed  Properties
(the "Leases"); and

(ii) an initial  undivided 25% of all rights held by the Company  Parties at the
date of this Agreement to earn interests in oil and gas leases by drilling wells
or by any other means (the  "Earning  Wells") on such  leases  after the Closing
Date  pursuant  to those  certain  agreements  set forth in Part II of  Schedule
4.03(a)  ("Earning  Agreements"),  together with an initial undivided 25% of all
obligations  of the  Company  Parties  at the date of this  Agreement  under the
Earning Agreements,  exclusive however of any rights or obligations with respect
to the Developed  Properties  (all of such rights and obligations of the Company
Parties,  subject  to such  exclusion,  being  herein  collectively  called  the
"Earning Rights").

     The above  described  interests in the Leases,  the Earning  Rights and the
Earning Agreements  (collectively  referred to herein as the "Initial Interest")
will be conveyed from the Company  Parties to the  Purchasers at the Closing and
have an agreed aggregate fair market value of $22,000,000.

     All of the  Company  Parties'  existing  wells and related  facilities  and
leasehold  interests in the  Designated  Wellbore Areas shall be retained by the
Company  Parties.  These wells and facilities  and, to the extent they cover the
Designated  Wellbore Areas,  the concerned  leases are identified on Exhibit B-1
and are  referred to as the  "Developed  Properties."  As used  throughout  this
Agreement, the term "Designated Wellbore Area" means the 40-acre quarter-quarter
section of the public land survey in which a  concerned  well is located,  other
than in the CD, Gamma Ray and Muddy Creek Federal  Exploratory Units in Wyoming.
In the CD,  Gamma  Ray and  Muddy  Creek  Federal  Exploratory  Units,  the term
"Designated Wellbore Area" means the 160-acre quarter section of the public land
survey in which a concerned well is located.

     The oil and gas leases  identified  on Exhibit B-2 (the  "Special  Phillips
Leases") are leases in which the Company Parties own an interest and are subject
to existing agreements with Phillips Petroleum Company ("Phillips")  pursuant to
which the Company has the right to earn additional interests by drilling certain
wells.  No interests in these leases will be assigned to the  Purchasers  on the
Closing Date; however,  the Purchasers will have the right to participate in the
drilling  of these  wells and earn  interests  in the  Special  Phillips  Leases
pursuant to Section 1.04.

Section  1.02  Transfer of Shares.  At the  Closing,  the Company  Parties  will
execute and deliver to the Purchasers an Assignment, Bill of Sale and Conveyance
and Assignments of Contract Rights and  Obligations,  substantially in the forms
attached  hereto as Exhibits  C-1, C-2 and C-3,  covering  the Initial  Interest
(except  for those  Earning  Rights for which  Required  Consents  have not been
obtained as of such date,  which will become subject to Section 6.15)  effective
as of the  Closing  Date  (the  "Closing  Assignments")  against  (i) the  sale,
transfer and delivery by Brek to the Company of the Brek Shares,  free and clear
of all taxes,  liens,  security  interests,  pledges,  restrictions on transfer,
encumbrances and adverse claims, and (ii) the sale, transfer and delivery by the
Stockholders  to the Company of the  Stockholder  Shares,  free and clear of all
taxes,   liens,   security   interests,   pledges,   restrictions  on  transfer,
encumbrances and adverse claims.

     At the Closing, the Company Parties shall also execute and deliver separate
assignments  of the  leasehold  interests  to be  assigned  at the  Closing,  as
necessary,  on officially  approved forms in sufficient  counterparts to satisfy
applicable  statutory and regulatory  requirements.  Such  assignments  shall be
deemed to contain all of the provisions set forth in the Closing  Assignment set
forth in Exhibit C-1. The interests  conveyed by such separate  assignments  are
the  same,  and not in  addition  to,  the  interests  conveyed  in the  Closing
Assignment set forth in Exhibit C-1.

     At the  Closing,  the  Purchasers  shall  ratify,  confirm  and join in all
operating  agreements  (whether a joint operating  agreement or a unit operating
agreement)  to which a Company  Party or any of its  subsidiaries  is bound that
relate to the  leases  in which  interests  are then  being  assigned.  All such
operating agreements are listed or otherwise referred to on Schedule 4.03(a). If
a Company Party or any of its subsidiaries are then contractually bound to enter
into an operating agreement at a later date or upon satisfaction of a condition,
then the  Purchasers  shall be  similarly  bound to enter  into  such  operating
agreement  at the  same  time as  such  Company  Party  or its  subsidiary.  The
contracts containing all such obligations are listed or otherwise referred to on
Schedule 4.03(a).  If a Company Party is assigning  interests in any leases that
are not then subject to an operating agreement or a contractual promise to enter
into an operating  agreement,  then such Company Party,  and the Purchasers will
enter into joint operating agreements each in the form attached as Exhibit D. In
the  event of any  conflict  between  this  Agreement  and the terms of any such
operating  agreement  (whether a joint  operating  agreement or a unit operating
agreement), the terms of this Agreement shall control.

     At the  Closing,  (i) Brek shall  deliver to the Company  all  certificates
representing  the  Brek  Shares,  duly  endorsed  to the  Company  and  (ii) the
Stockholders  shall  deliver to the Company all  certificates  representing  the
Stockholder Shares, duly endorsed to the Company.  All signatures of endorsement
on certificates (or on stock powers accompanying the certificates)  representing
shares of Common  Stock or  Preferred  Stock  delivered  at the Closing  must be
guaranteed by a firm which is a member of a registered  United  States  national
securities exchange or of the National Association of Securities Dealers,  Inc.,
a commercial  bank or trust  company  having an office or  correspondent  in the
United States, or an "eligible guarantor institution" within the meaning of Rule
17Ad-15 under the Securities Exchange Act of 1934 (the "Exchange Act").

Section 1.03      Right to Additional Interest.


(a) The  Purchasers  shall have the right but not the  obligation to purchase at
their sole option an  additional 5% undivided  interest in the Company  Parties'
right,  title and interest in the leases and rights  conveyed to the  Purchasers
pursuant to Section 1.01, more particularly defined as the "Additional Interest"
in Section 1.03(g) below, by paying  additional  consideration to the Company in
the amount of  $10,500,000  in the manner and under the terms  described  in (b)
below.

(b) Upon  receipt by the Company of a payment in the amount of  $5,250,000  (the
"First  Option  Payment")  on or before  January 1, 2004,  then the Company will
execute  and  deliver  to  the  Purchasers  an  assignment  of  one-half  of the
Additional  Interest (the "First One-Half  Interest")  substantially in the form
(except for the amount of the interest being conveyed and the effective date) as
the Closing  Assignment set forth in Exhibit C-1. Upon receipt by the Company of
the remaining  payment of $5,250,000 (the "Second Option  Payment") on or before
January 1, 2005,  the Company  will  execute and  deliver to the  Purchasers  an
assignment  of the second  one-half  of the  Additional  Interest  (the  "Second
One-Half  Interest")  substantially  in the form (except for the interest  being
conveyed and the effective date) as the Closing  Assignment set forth in Exhibit
C-1.  If the  Purchasers  fail to pay the First  Option  Payment on the due date
thereof,  the  Purchasers  shall forfeit  their right to acquire any  Additional
Interest  hereunder.  If the Purchasers  timely pay the First Option Payment but
fail to pay the Second  Option  Payment on or before the due date  thereof,  the
Purchasers  shall forfeit their right to acquire the Second  One-Half  Interest.
The obligations of the Purchasers to timely pay the First Option Payment and the
Second Option Payment  (collectively,  the "Option Payments") hereunder in order
to exercise their right to acquire the Additional Interest shall be absolute and
unconditional  and  shall  not be  affected  or  reduced  by any  circumstances,
including,  without  limitation,  (i)  any  setoff  (except  for  the  reduction
described in Section 6.18, if applicable),  counterclaim, recoupment, defense or
other  right  which a Purchaser  may have  against a Company  Party or any other
third party;  (ii) any defect in title to the Properties to which the Purchasers
will receive an interest  hereunder;  (iii) any disputes arising under or rights
asserted  by the  Purchasers  under any  lease,  operating  agreement,  farm-out
agreement or similar  agreement  relating to the  Properties;  or (iv) any other
circumstance  or  happening  of any  nature  whatsoever,  similar  to any of the
foregoing;  it being the express  intention  of the Parties that failure to make
any Option  Payment on or before the due date thereof for any reason will result
in the forfeitures set forth in this Section 1.03.

(c) If the due date for any Option Payment falls on a date that is a holiday for
banks located in Denver,  Colorado,  such Option Payment shall become due on the
next date that such banks are open for  business.  Each Option  Payment shall be
made  by  wire  transfer  to the  Company's  account  pursuant  to  instructions
delivered by the Company to Brek in accordance with Section 8.02.

(d) At the time of assignment by the Company of the First One-Half  Interest and
the Second  One-Half  Interest (if such interests are assigned to the Purchasers
in compliance with Section 1.03(b)),  the Company Parties shall also execute and
deliver  separate  assignments  of the  leasehold  interests to be assigned,  as
necessary,  on officially  approved forms in sufficient  counterparts to satisfy
applicable  statutory and regulatory  requirements.  Such  assignments  shall be
deemed  to  contain  all of  the  provisions  set  forth  in  the  corresponding
assignment described in Section 1.03(b). The interests conveyed by such separate
assignments are the same, and not in addition to, the interests  conveyed in the
assignments described in Section 1.03(b).

(e) Before January 1, 2004, and  thereafter,  if the Purchasers have paid to the
Company on or before their  respective due dates all Option  Payments to be paid
to the Company  through the then current date as required by the  provisions  of
Section 1.03(b),  the Purchasers shall have the right to participate in any well
drilled on the Leases or any Earning  Well for the Full  Purchaser  Interest (as
defined  in (g)  below)  therein.  If the  Purchasers  participate  or  fail  to
participate on such terms, the following provisions shall apply:

          (1) If the Purchasers  participate for the Full Purchaser  Interest in
     the drillingof a well drilled on the Leases,  (A) the Company  Parties will
     assign or cause to be assigned to the Purchasers  the  additional  interest
     they would have acquired in the well and the acreage  within the Designated
     Wellbore Area in which such well is located  pursuant to Section 1.03(b) as
     if all Option  Payments had been timely made, and (B) such well and acreage
     shall be excepted from any Additional Interest subsequently assigned to the
     Purchasers.

          (2) If the  Purchasers  fail to  participate  for the  Full  Purchaser
     Interest  in any such  well  located  on a Lease,  then  such  well and the
     Designated  Wellbore  Area in which such well is located  shall be excepted
     from any Additional Interest  subsequently  assigned by the Company Parties
     to the Purchasers and reserved by the Company Parties.

          (3) If the Purchasers  participate for the Full Purchaser  Interest in
     the  drilling of an Earning  Well,  (A) the Company  Parties will assign or
     cause to be assigned to the Purchasers (i) the full interest the Purchasers
     would have acquired in the Earning Well and the Designated Wellbore Area in
     which the Earning  Well is located  pursuant  to Section  1.03(b) as if all
     Option  Payments  had been  timely  made and (ii) an  undivided  25% of the
     interests earned by the Company Parties in any additional  acreage pursuant
     to the provisions of the applicable Earning Agreement, and (B) such Earning
     Well and Designated  Wellbore Area (but not the additional acreage referred
     to in  subclause  (A)(ii)  above)  shall be  excepted  from any  Additional
     Interest  subsequently  assigned  to the  Purchasers  and  reserved  by the
     Company Parties.

          (4) If the  Purchasers  fail  to  participate  or the  Full  Purchaser
     Interest  in any  Earning  Well,  then  there  shall be  excepted  from any
     Additional Interest subsequently assigned to the Purchasers and reserved by
     the Company  Parties (i) such Earning Well,  (ii) all acreage earned by the
     Company  Parties  through the drilling of such Earning Well,  and (iii) all
     other  acreage  that the Company  Parties may earn  through the drilling of
     subsequent wells under the terms of the applicable  Earning  Agreement (but
     only if the Company  Parties would have lost all such other acreage if they
     would have failed to  participate  for their full  interest in such Earning
     Well).

          (5) The Purchasers'  rights under this Section 1.03(e) shall terminate
     on the date on which the  Purchasers  receive an  assignment  of the Second
     One-Half Interest  pursuant to Section 1.03(b) or, if earlier,  the date on
     which the Purchasers  have forfeited  their right to acquire the Additional
     Interest pursuant to this Section 1.03.

(f) If the  Purchasers  acquire 25% of any  Remaining  Interest  pursuant to the
provisions  of  Section  6.16(b),  they shall  have the  option to  purchase  an
additional portion of such Remaining Interest  aggregating 5% thereof,  upon the
following terms and conditions:

          (1) The Purchasers  may purchase an additional  2.5% of such Remaining
     Interest  ("First  Option  Interest")  if the  Purchasers  receive  or have
     received an assignment of the First One-Half  Interest  pursuant to Section
     1.03(b).  Provided it timely  exercises  its option to  purchase  the First
     Option  Interest,  the  Purchasers  may also purchase  another 2.5% of such
     Remaining  Interest ("Second Option Interest") if the Purchasers receive or
     have  already  received  an  assignment  of the  Second  One-Half  Interest
     pursuant to Section  1.03(b).  Any election by the  Purchasers  to exercise
     their option to purchase  either of such interests shall be made in writing
     and received by the Company not later than five (5) days after the later of
     (i) the date on which the  Purchasers  receive the  assignment of the First
     One-Half Interest or the Second One-Half Interest, as applicable,  and (ii)
     the date on which the  Purchasers  receive  notice  that they may acquire a
     portion of the Remaining  Interest.  If the Purchasers fail to exercise the
     option,  they shall be deemed  conclusively to have elected not to purchase
     the above described interest.

          (2) The  purchase  price for the First  Option  Interest or the Second
     Option Interest (either,  an "Option Interest") shall be an amount equal to
     2.5% of the aggregate  out-of-pocket  costs incurred by the Company Parties
     to  acquire  and  maintain  the  Remaining  Interest  (including,   without
     limitation,  all rentals,  delay rentals and minimum  royalties paid by the
     Company Parties attributable to the Remaining Interest).

          (3) At the closing of the sale of an Option  Interest,  the Purchasers
     shall pay the purchase  price for the Option  Interest in same-day funds to
     the Company  Parties and the Company  Parties  shall execute and deliver to
     the Purchasers an assignment of the Option Interest.  Such assignment shall
     warrant title to the Option Interest  against all liens,  restrictions  and
     encumbrances  created  by,  through or under the Company  Parties,  but not
     otherwise and subject to the Permitted Encumbrances.

          (4) If (i) the Remaining Interest is acquired under Section 6.16(b) in
     the  form  of a  farmout  agreement,  exploration  agreement  or any  other
     agreement  that requires one or more wells to be drilled in order to earn a
     leasehold  interest ("Farmout  Agreement"),  (ii) the Purchasers receive an
     assignment  of an interest in the  additional  acreage  described in clause
     (ii) of the first grammatical  paragraph of Section 6.16(e),  and (iii) the
     Purchasers  subsequently  receive  an  assignment  of  the  First  One-Half
     Interest  pursuant to Section 1.03(b),  then, if the Purchasers so elect in
     the manner set forth in Section 1.03(f)(1) with respect to the First Option
     Interest,  the Company Parties shall assign to the Purchasers an additional
     interest in the acreage  described in such clause (ii) being the difference
     between  27.5% and 25% of the  interests  earned by the Company  Parties in
     such acreage and the Purchasers shall pay the Company Parties an additional
     amount  equal to 2.5% of the Company  Parties'  acquisition  costs for that
     Interest as described in clause (c) of Section 6.16(b).

          (5) If (i) the Remaining Interest is acquired under Section 6.16(b) in
     the form of a Farmout Agreement,  (ii) the Purchasers receive an assignment
     of an interest in the  additional  acreage  described in clause (ii) of the
     first  grammatical  paragraph of Section 6.16(e),  and (iii) the Purchasers
     subsequently receive an assignment of the Second One-Half Interest pursuant
     to Section  1.03(b),  then,  if the  Purchasers  so elect in the manner set
     forth in Section 1.03(f)(1) with respect to the Second Option Interest, the
     Company  Parties shall assign to the  Purchasers an additional  interest in
     the acreage described in such clause (ii) being the difference  between 30%
     and 27.5% of the  interests  earned by the Company  Parties in such acreage
     and the Purchasers shall pay the Company Parties an additional amount equal
     to 2.5% of the  Company  Party's  acquisition  costs for that  Interest  as
     described in clause (c) of Section 6.16(b).

          (6) the Purchasers'  rights under this Section 1.03(f) shall terminate
     on the date on which the  Purchasers  receive an  assignment  of the Second
     One-Half Interest  pursuant to Section 1.03(b) or, if earlier,  the date on
     which the  Purchasers  have  forfeited  their  right to acquire  Additional
     Interest pursuant to this Section 1.03.

(g) As used herein,  the  following  terms shall have the meaning  given them as
follows:

          "Additional  Interest"  means,  subject to the  provisions  of Section
     1.03(e),  (i) an  undivided  5% of the Company  Parties'  right,  title and

     Parties through the exercise of the Earning Rights on or before the date on
     which the  Purchasers  are entitled to an assignment of the First  One-Half
     Interest or the Second One-Half Interest pursuant to Section 1.03(b),  less
     and except,  however,  (A) the Earning  Wells and the  Designated  Wellbore
     Areas in which such  Earning  Wells are located  and (B) if the  Purchasers
     fail to  participate  in the  drilling  of an  Earning  Well  for the  Full
     Purchaser  Interest,  (y) any acreage  earned  through the drilling of such
     Earning  Well and (z) all  other  acreage  that the  Company  Parties  earn
     through the  drilling of  subsequent  Earning  Wells under the terms of the

     lost all such other  acreage if the  Company  Parties  would have failed to
     participate  for their full  interest  in such  Earning  Well) and (iii) an
     undivided  5% interest in all Earning  Rights,  to the extent such  Earning
     Rights remain in effect at the date on which the Purchasers are entitled to
     an  assignment  of the  First  One-Half  Interest  or the  Second  One-Half
     Interest pursuant to Section 1.03(b) (as applicable), provided that, if the
     Purchasers  fail to  participate in the drilling of an Earning Well for the
     Full Purchaser Interest, there shall be excluded from this clause (iii) all
     Earning  Rights under the  applicable  Earning  Agreement  (but only if the
     Company  Parties  would have lost all such  Earning  Rights if the  Company
     Parties  would have failed to  participate  for their full interest in such
     Earning Well).

          "Full Purchaser  Interest" means (i) with respect to a well drilled on
     the  Leases,  the  sum of (A)  the  full  amount  of  the  interest  in the
     applicable  Leases  assigned to the  Purchasers at the Closing  pursuant to
     Section 1.02 and (B) the additional  interest in the applicable  Leases the
     Purchasers  would  acquire  pursuant  to  Section  1.03(a)  if  all  of the

     parties  with  respect to the  drilling  of the  Earning  Well and  earning
     leasehold  interests  as held by the  Company  Parties  at the date of this
     Agreement.

Section 1.04      Special Phillips Leases.


(a) Southern Leases.  Pannonian  currently owns different leasehold interests in
different  depths  in the lands  covered  by  Federal  Leases  UTU-018260-A  and
UTU-058148 (the "Southern Leases").  Phillips has granted Pannonian a farmout by
which if  Pannonian  drills a test well to a certain  depth by December 31, 2002
and completes  such well as a producer,  then Phillips and Pannonian  will enter
into a cross  conveyance  that would result in (i) Pannonian  having 100% of the
leasehold  interest as to all depths in the  80-acre  tract in which the well is
located before payout (70% after payout), and (ii) Pannonian and Phillips having
70% and 30% leasehold interests, respectively, in the other lands covered by the
Southern Leases.  The Purchasers will have the right to participate for the Full
Purchaser Interest in such test well, and if the well is completed as a producer
in  accordance  with the terms of the farmout,  the  Purchasers  will receive an
assignment  of 30% of  Pannonian's  interests in the  Southern  Leases after the
above  cross  conveyance  has been  executed  and  delivered.  In such case,  no
interest in the  Southern  Leases will be  included in any  Additional  Interest
subsequently assigned to the Purchasers. If the well is abandoned as a dry hole,
the Purchasers will receive an assignment of 25% of Pannonian's  interest in the
Southern Leases.  If Pannonian  decides not to drill the well in accordance with
the  terms of the  farmout,  Pannonian  will  assign  to the  Purchasers  25% of
Pannonian's  interest in the  Southern  Leases as soon as  Pannonian  makes such
decision and an additional  5% of  Pannonian's  interest in the Southern  Leases
will become a part of the Additional Interest.

(b) Nonconsent  Tracts.  Phillips has elected not to participate in the drilling
of four wells  proposed by Pannonian to be commenced  prior to December 31, 2002
on four 320-acre tracts identified on Exhibit B-2 (the "Nonconsent Tracts"). For
each such well on which  drilling  is  commenced  prior to  December  31,  2002,
Phillips has agreed to assign to Pannonian its entire interest in the Nonconsent
Tract on which  such  well is  drilled.  The  Purchasers  will have the right to
participate  for the Full  Purchaser  Interest  in each  such  well,  and if the
Purchasers do so participate, then in each such case the Purchasers will receive
an  assignment  of 30%  of  Pannonian's  entire  interest  in the  corresponding
Nonconsent  Tract  following  the  assignment  by Phillips to  Pannonian  of its
interest  in  such   Nonconsent   Tract.  In  such  case,  no  interest  in  the
corresponding  Nonconsent  Tract will be  included  in any  Additional  Interest
subsequently assigned to the Purchasers. If the drilling of any such well is not
commenced  prior to December 31, 2002,  such that  Phillips  does not assign its
interest in the  corresponding  Nonconsent  Tract to Pannonian,  Pannonian  will
assign to the Purchasers 25% of Pannonian's interest in such Nonconsent Tract as
soon as Pannonian  decides not to commence such drilling  prior to such date and
such Nonconsent  Tract shall be deemed to be a part of the Initial  Interest and
an additional 5% of Pannonian's  interest in such Nonconsent Tract will become a
part of the Additional Interest.

Section 1.05 Closing. The closing (the "Closing" of the sale and purchase of the
Shares  shall take place at the offices of the Company in Denver,  Colorado,  at
10:00  a.m.  on July 16,  2002,  or at such  other  place,  date and time as the
parties hereto may agree (the "Closing Date").

Section 1.06 Subsidiaries. The Company holds title to the Properties through its
wholly owned  subsidiaries,  Pannonian and San Joaquin.  The Company shall cause
Pannonian  or San  Joaquin,  as  applicable,  to  execute  all  assignments  and
conveyances  relating to the Properties and otherwise to perform the obligations
of the Company relating to the Properties under this Agreement.

Section 1.07 Romanian License Excluded. Pannonian currently holds an oil and gas
concession (the  "Concession")  issued by the country of Romania that it intends
to assign to Pannonian  International  Ltd. For purposes of this Agreement,  the
Concession  shall be deemed not to be owned by a Company  Party or any Affiliate
thereof, and Purchasers shall acquire no interest in the Concession hereunder.

          asserting such rights has expired without an exercise of such rights;

               (9)  required  third  party  consents to  assignments  or similar
          agreements  with respect to which (i) waivers or consents are obtained

               (11) all  defects and  irregularities  affecting  the  Properties
          which  individually or in the aggregate do not or could not operate to

consummate the transactions contemplated hereby.

(c) No Notice of Violation. With respect to the Properties, no Company Party has
received  notice (i) of a material  violation  of any statute,  law,  ordinance,
regulation,  permit, rule or order of any federal,  state or local government or

from the parties named on Schedule 4.03(e).  The term "Required Consent" means a
consent that if not obtained by Closing would  invalidate  the conveyance of the
Properties;  provided, however, that consents and approvals that are customarily
obtained after Closing (such as federal and state approvals of assignments), and
other  consents  that  do not  specifically  invalidate  the  conveyance  if not
obtained are not "Required Consents". The Company Parties shall use commercially
reasonable efforts to obtain all Required Consents.

Section 4.04 Absence of Further  Requirements.  Except for applicable  reporting
requirements under the Exchange Act and Permitted Encumbrances,  no filing with,
or consent, approval, authorization, order, registration, notification or decree

necessary  or  required  for the  performance  by the  Company  Parties of their

this Agreement.

or commissions in connection with the transactions contemplated hereby.

Parties are so operated  in  compliance  with  applicable  laws and  regulations

With respect to Environmental Laws,  compliance  therewith is deemed to include,

     Contaminants  into the indoor or outdoor  environment  (including,  without
     limitation,  ambient air,  surface water,  groundwater,  land,  surface and
     subsurface  strata) or otherwise  relating to the manufacture,  processing,
     distribution,  use, treatment,  storage, Release,  transport or handling of
     Hazardous Substances, Oils, Pollutants or Contaminants.

          (2) "Hazardous Substances, Oils, Pollutants or Contaminants" means all

investigation by any person, entity,  administrative agency or governmental body
pending  or, to the Company  Parties'  Knowledge,  threatened  against a Company

and the  Developed  Properties  represent all of the oil and gas leases owned by
the Company Parties as of the date of this  Agreement.  The agreements set forth

Rights owned by the Company Parties as of the date of this Agreement.

ARTICLE VI

                                    COVENANTS

Section 6.01 Data Sharing by the Company  Parties of Information  Obtained Prior
to Closing.

(a) Upon request after the Closing and continuing  until there has been a Change
of Control  (as  hereafter  defined)  of the  Company,  Brek or Brek  Petroleum,
whichever  shall  first  occur,  the  Company  Parties  will  give Brek and Brek
Petroleum timely access to and the ability to copy, at such party's expense, all
raw data obtained prior to the Closing and  interpretations  or analyses of such
data prepared prior to the Closing (but expressly  excluding  interpretations or
analyses  of such data  prepared  after the  Closing)  in the  Company  Parties'
possession and produced from drilling or other work conducted before the Closing
on the Properties and the Developed Properties;  provided, however, that if such
data is protected by confidentiality or non-disclosure  restrictions in favor of
third  parties and such third  parties do not consent to the  disclosure of such
data to Brek or Brek  Petroleum  or  giving  copies of such data to Brek or Brek
Petroleum,  then the Company  Parties  shall have no  obligation to Brek or Brek
Petroleum  under  this  Section  6.01 with  respect  to such data  other than to
provide Brek or Brek  Petroleum  with a  description  of such data and a copy of
such non-disclosure restrictions, and to cooperate with and assist Brek and Brek
Petroleum in attempting to obtain any such third party  consents,  provided that
the Company  Parties  shall not be required to incur any out of pocket  costs or
expenses in doing so.

(b) For  purposes of this  Agreement,  a "Change of Control" in an entity  shall
have occurred upon the happening of any of the following events:

(i) the entity is merged,  consolidated or reorganized into or with or sells all
or substantially all of its assets to another  corporation or other legal person
(other  than an  Affiliate  of such  entity),  and as a result  of such  merger,
consolidation,  reorganization  or sale (A) less than a majority of the combined
voting power of the then-outstanding  securities of the surviving corporation or
person (in the case of a merger,  consolidation or  reorganization) or the buyer
(in the case of a sale of assets) immediately after such transaction are held in
the aggregate by the holders of voting stock of the entity  immediately prior to
such transaction and (B) persons serving as Directors of the entity  immediately
prior to the transaction constitute less than a majority of the Directors of the
surviving  corporation or legal person  immediately  after  consummation  of the
transaction; or

(ii) if during any one (1) year period,  individuals who at the beginning of any
such period  constituted  the  Directors  of the entity  cease for any reason to
constitute at least a majority thereof,  unless the election,  or the nomination
for election by the entity's shareholders,  of each Director of the entity first
elected during such period was approved by a vote of at least  two-thirds of the
Directors of the entity then still in office who were Directors of the entity at
the beginning of any such period.

(c) For the avoidance of doubt,  the Parties  specifically  acknowledge that the
Company  Parties  and their  subsidiaries  shall have the free and  unrestricted
right  to  transfer,  encumber,  drill,  and  deal in all of  their  properties;
provided, however, that the Company Parties shall not transfer, encumber (except
for  Permitted  Encumbrances)  or deal  in,  until  the  last of the  Additional
Interest is assigned to the Purchasers or April 1, 2005,  whichever  shall first
occur, the quantum of interest to which the Purchasers may be entitled under the
terms of this Agreement, and shall leave unassigned and unencumbered (except for
Permitted  Encumbrances) at least such quantum of interest as the Purchasers may
be entitled under the terms of this Agreement.

Section 6.02 Assignment  Following  Cessation of Production:  Wyoming  Developed
Properties.  If any of the six Wyoming wells  identified in Exhibit B-1 are ever
plugged  and  abandoned,  and if no new  well is  spudded  in the  corresponding
Designated  Wellbore  Area  within  90  days  after  the  plugging  date of that
abandoned  well,  then Pannonian  shall promptly assign to Brek an undivided 25%
(or such  greater  interest  as may be  required  as a result  of  Brek's  prior
exercise of the option set forth in Section 1.03) of  Pannonian's  right,  title
and interest in the leases  covering the Designated  Wellbore Area at that date,
but only to the extent such leases cover the Designated Wellbore Area. Following
any such  assignment,  the  leasehold  interests  will be  deemed  to be  leases
conveyed to the  Purchasers  pursuant  to Section  1.01,  so that the  leasehold
interests,  to the  extent  they cover the  Designated  Wellbore  Area,  will be
included in the interests to be conveyed upon any subsequent exercise by Brek of
its option in Section 1.03.

Section 6.03 Well Bore Agreements. This Agreement contemplates two situations in
which  a  Party  may  have a  greater  interest  in a  particular  well  and the
Designated  Wellbore  Area in which  the well is  located  than the Party has in
adjoining lands: first, in Section 1.01, where the Company Parties are retaining
100% of their interest in Developed  Properties and, second, in Section 1.03(e),
where the Purchasers may under certain circumstances participate in new drilling
at the level they would own if all of the Additional  Interest had been conveyed
to them,  retaining such interest in the  newly-drilled  well and the Designated
Wellbore Area in which the well is located even if they do not later receive all
of the Additional Interest. In these situations, the Parties specifically intend
that each Party  shall bear its share of costs and  receive its share of revenue
from the concerned well and Designated  Wellbore Area (as to all depths in which
the Parties have an interest)  without regard to any different result that would
be required based upon the applicable  spacing unit or  participating  area. The
Parties  irrevocably commit to enter into and to record and file in the relevant
governmental    offices   appropriate    wellbore   agreements   stating   that,
notwithstanding  any larger or different  spacing units or  participating  areas
that may be established from time to time, the Company Parties, on the one side,
and the Purchasers, on the other side, agree that all working interest costs and
the burden of all overriding  royalties created after the date of this Agreement
shall,  as to the  concerned  wells,  be  borne  by  the  Parties  in  the  same
proportions that they own interests in such wells, and that all working interest
production  and working  interest  net  revenue  from these wells shall be owned
solely by the Parties in the same  proportions  that they own interests in these
wells. By way of illustration,  the Parties agree, as between  themselves,  that
the Company Parties will own 100% of the Developed Properties and be entitled to
100% of the revenues from the wells shown on Exhibit B-1, even if another result
would be dictated by applicable  spacing orders or unit  agreements.  Similarly,
the Parties agree, as between  themselves,  that, so long as the Purchasers paid
30% of the costs of a newly-drilled  well where permitted under Section 1.03(e),
the Purchasers will own 30% of such  newly-drilled  wells and be entitled to 30%
of the  revenues  from such wells,  even if another  result would be dictated by
applicable  spacing orders or unit  agreements.  From and after the date of this
Agreement,  each Party covenants not to create any overriding royalty that would
have the effect of burdening production attributable to any other Party obtained
from wells physically  located on the concerned  Designated  Wellbore Areas. The
Parties recognize that landowner royalties and overriding royalties in existence
at the date of this Agreement must be paid in accordance  with relevant  spacing
orders or unit agreements and that third-party  working interest owners may have
rights that are not affected by the wellbore agreements described above, but the
Parties intend,  as between  themselves,  to ensure that working interest costs,
subsequently created overriding royalty interests,  and revenues associated with
these  particular  wells,  even if  recompleted,  deepened or twinned within the
Designated  Wellbore  Area,  shall be the burdens and benefits of the Parties in
accordance with their interests in the concerned wells  themselves,  rather than
in the  spacing  units or  participating  areas.  In  addition  to the  wellbore
agreements described above, the Parties  specifically  undertake to execute such
other or additional  instruments  as may reasonably be necessary to fulfill this
intention.

Section  6.04  Wyoming  Operatorship.   As  additional   consideration  for  the
conveyance of the Initial Interest by the Company Parties to the Purchasers, the
Purchasers  hereby  irrevocably  commit and agree to  support  and to vote their
interests in favor of Pannonian in the event any new or successor operator is at
any time to be designated or elected for the CD federal unit in Sublette County,
Wyoming.

Section 6.05 Termination of Share Exchange Agreements. Brek shall deliver to the
Company the  agreements  described  in Section  5.02(e) on or before the Closing
Date.

Section  6.06  Commercially  Reasonable  Efforts.   Subject  to  the  terms  and
conditions  herein provided,  each of the parties hereto covenants and agrees to
use commercially  reasonable efforts to take or cause to be taken, all action or
do,  or cause to be done,  all  things  necessary,  proper  or  advisable  under
applicable   laws  and   regulations   to  consummate  and  make  effective  the
transactions  contemplated by this Agreement.  Nothing herein shall obligate any
Party to incur any expense or obligation with respect to obtaining or attempting
to obtain any third party consent or  authorization  contemplated or required by
Section 6.01, 6.02 or 6.04.

Section  6.07  Significant  Transaction  with the  Company.  Each  Party  hereby
represents to the other Parties that it has had no  discussions  with any person
regarding a tender offer for the Company's  outstanding  common stock,  a merger
with the  Company  (regardless  of  whether  the  Company  would  have  been the
surviving  entity) or a sale by the Company of all or  substantially  all of the
Company's assets (each, a "Significant  Transaction"),  and it has no first hand
Knowledge of any such Significant Transaction.

Section 6.08 Transfer Taxes.  All sales, use or other taxes (other than taxes on
gross  income,  net  income  or  gross  receipts),   duties,   levies  or  other
governmental  charges and  recording  or filing fees or expenses  incurred by or
imposed  with  respect to the  property  transfers  undertaken  pursuant to this
Agreement shall be the responsibility of, and shall be paid by, the Purchasers.

Section  6.09 Ad Valorem and Similar  Taxes.  All ad  valorem,  gross  products,
production, excise, severance and similar taxes that are payable with respect to
ownership  or  operation  of the  Properties  to be  assigned  pursuant  to this
Agreement or production therefrom prior to the effective date of such assignment
shall be paid by the Company Parties when due. The Purchasers shall pay when due
all such taxes payable after the effective date of such assignment.

Section 6.10      Further Cooperation.

(a) After the Closing and the date of the assignment of any Additional  Interest
pursuant to this  Agreement,  each Party at the request of the other and without
additional  consideration,  shall  execute  and  deliver,  or shall  cause to be
executed and delivered, from time to time such further instruments of conveyance
and transfer and shall take such other action as the other Party may  reasonably
request to convey and deliver the applicable Initial Interest and (to the extent
earned) the Additional  Interest to the Purchasers and to accomplish the orderly
transfer of such properties to the Purchasers in the manner contemplated by this
Agreement.  After the Closing and the date of the  assignment of any  Additional
Interest  pursuant to this  Agreement,  the Parties  will  cooperate to have all
proceeds received attributable to the applicable properties to be transferred to
the  Purchasers  to be paid  to the  proper  Party  hereunder  and to  have  all
expenditures to be made with respect to such properties to be made by the proper
Party hereunder.

(b) Promptly  following the Closing,  the Purchasers shall record or file in the
appropriate  real  property   records  or  with  the  appropriate   Governmental
Authorities,  as applicable,  the assignment  instruments  delivered pursuant to
Sections 1.02 and 1.03.  The  Purchasers  shall send copies of these recorded or
filed  copies  showing  the  recording  and filing  information  to the  Company
promptly  following  the  return of the  assignment  instruments  by the  county
recorders and Governmental Authorities.

(c) If, following the Closing,  the Company or the Purchasers  discover that any
oil or gas  leases or rights to acquire  an  interest  in an oil or gas lease by
drilling wells or by any other means owned by the Company as of the date of this
Agreement  other than the  Developed  Properties  ("Missed  Leases  and  Earning
Rights")  were not  assigned  to the  Purchasers  pursuant  to the terms of this
Agreement,  the Company shall forthwith assign the appropriate  interest in such
Missed Leases and Earning Rights to the Purchasers that would have been assigned
but for such oversight.

(d) The Parties will cooperate with each other in good faith with respect to the
timing of the  drilling of the Earning  Wells in order to provide for an orderly
drilling  program of the wells on such leases within the permitted  time periods
and the avoidance of several  material  expenditures  being  required to be made
within an unreasonably short time period.

Section 6.11 Assumption. Subject to Section 6.09, as of the Closing and the date
of the assignment of any Additional  Interest  pursuant to this  Agreement,  the
Purchasers  shall assume all obligations  that are attributable to the ownership
of the Properties to be transferred at such date, whether or not attributable to
periods before or after the effective date of the  assignments  made pursuant to
this  Agreement,  including  without  limitation  (i) all  obligations  (whether
arising by statute, regulation, court order or by contract) to properly plug and
abandon  all  wells  and  remove  all  related  equipment  now  located  on such
Properties or hereafter placed on such  Properties,  and all such obligations to
cleanup and restore the lands  constituting or related to such Properties,  (ii)
all taxes,  including  ad valorem  taxes,  attributable  to such  Properties  or
Hydrocarbons produced therefrom,  and (iii) all liabilities attributable to such
Properties  arising under any Environmental  Laws (such assumed  obligations and
liabilities  being  hereinafter   collectively   referred  to  as  the  "Assumed
Obligations");  provided,  however,  that this Section 6.11 shall not affect the
obligations  of the Company  Parties for their  representations  and  warranties
contained in this Agreement.

Section 6.12  Confidentiality.  All information or documents furnished hereunder
by any Party hereto or any other party shall be kept  confidential  by the Party
to whom it is furnished  (and such Party shall use its best efforts to cause its
agents and  representatives  to maintain the  confidentiality of such documents)
and will not be used by such  Party to the  detriment  of the  other  Party.  In
addition,  for a period of five years following the Closing, the interpretations
and  analyses of raw data on the Company  Properties  provided by the Company to
Brek or Brek  Petroleum  under  Section  6.01 may be  disclosed  by Brek or Brek
Petroleum only to employees, agents or representatives of Brek or Brek Petroleum
who execute and deliver to the Company a Confidentiality Agreement substantially
in the form  previously  delivered  by the  Company  to Brek.  In the  event the
transactions  contemplated  by this  Agreement are not  consummated,  each Party
shall return to the other Party or destroy all information  furnished  hereunder
and shall not  thereafter  use the same for any purpose  until such time as such
information becomes publicly available, except to the extent (i) it was known by
such other Party prior to being  received  other than  through the  violation or
breach of such Party or any other Party of any duty of confidentiality,  (ii) it
is or thereafter  becomes  lawfully  obtainable from other sources,  (iii) it is
necessary  or  appropriate  to disclose the same to any  governmental  authority
having  jurisdiction  over  the  Parties  or as  otherwise  may be  required  by
applicable  laws (to the extent  permitted by law,  the Party  intending to make
disclosure  in such  circumstances  shall give the other  Parties  hereto prompt
notice prior to making such  disclosures  so that such other  Parties may seek a
protective order or other appropriate remedy prior to such disclosure),  or (iv)
such duty of  confidentiality  is waived in writing by the other Party, and that
none of this information shall be used for competitive purposes.

(a) Each of the Purchasers  hereby  releases and discharges the Company  Parties
and their respective  officers,  directors,  agents and controlling persons, and
their respective successors,  assigns, heirs, executors and representatives,  of
and from all  liability,  actions,  causes of action,  claims,  demands,  suits,
damages and expenses (including attorneys' fees) of whatsoever nature which such
Party may now or hereafter  have or claim to have (whether  known or unknown) on

prior to the date  hereof,  excluding,  however,  all  transactions  and actions
arising out of this Agreement.

(c) The releases  contained in  subparagraphs  (a) and (b), above,  shall become
null  and  void  and  of no  further  effect  if the  transactions  contemplated
hereunder are terminated prior to the consummation thereof.

Section 6.14  Standstill.  For a period of two years  following the date of this
Agreement, except as expressly contemplated by the terms of this Agreement,

(a) each Company Party and each of the Purchasers  agrees that it shall not, and
shall not permit any of its  Affiliates to file, and each such party shall cause
its officers and directors not to file, any lawsuit against any other such party
or any  officer or  director  of any other  such  party that  alleges a cause of
action that arose before the date of this Agreement;

(b) each of the Purchasers shall not, and shall not permit any of its Affiliates

to enter  into,  directly  or  indirectly,  any merger or  business  combination
involving  the Company or any of its  subsidiaries  or to purchase,  directly or

subsidiaries, (iii) make, or in any way participate,  directly or indirectly, in

form, join or in any way participate in a "group" (within the meaning of Section
13(d)(3) of the Exchange Act) with respect to any voting security of the Company

and

Brek or any of its  subsidiaries  or to  purchase,  directly  or  indirectly,  a

or in any way  participate,  directly or indirectly,  in any  "solicitation"  of

seek to advise or influence any person with respect to the voting of, any voting
securities  of Brek or any of its  subsidiaries,  (iv) form,  join or in any way
participate in a "group" (within the meaning of Section 13(d)(3) of the Exchange

inconsistent with the foregoing,  or (vii) advise, assist or encourage any other

         None of the agreements contained in this Section 6.14 are intended to
restrict the voting of Gregory Pek as a director of the Company at any Company
Board of Directors meeting or the voting by Brek of the Brek Shares at any
Company stockholders meeting. Nothing in this Section 6.14 shall prohibit a
Party from proposing or participating in a transaction that would lead to a
Change of Control of another Party, provided that such transaction is approved
by the Board of Directors of such other Party prior to such Change of Control.

Section 6.15  Unobtained  Consents.  With respect to any of the Properties  that
would have been assigned to the  Purchasers at the Closing (or a later date) but
for the existence of  prohibitions  against or conditions to such transfer that,
if not satisfied, would result in the breach by a Company Party of a third party
agreement or would  terminate  or give a third party the right to terminate  any
rights of a Company  Party in and to such  Property  (any  such  Property  being
herein  referred  to as a  "Retained  Property"  and  any  such  prohibition  or
condition  being herein  referred to as a  "Restriction"),  the Company  Parties
agree to (a) use commercially reasonable efforts to cause such Restriction to be
satisfied or waived,  (b) transfer such Retained Property to the Purchasers when
and if such Restriction is satisfied or waived, and (c) pending the satisfaction
or waiver of such  Restriction and to the extent permitted by applicable law and
the terms of any applicable contracts or agreements,  and subject to any written
agreements  between the Company  Parties and the Purchasers  regarding  specific
Retained Properties,  hold the Retained Properties for the benefit of and use by
the Purchasers in order to permit the Purchasers to realize,  receive, and enjoy
rights and benefits, and bear burdens and obligations of the Retained Properties
in each case that are  substantially  similar to those that the Purchasers would
have been able to realize,  receive and enjoy, or bear, as applicable,  had such
Restriction been satisfied or waived.  The Parties shall enter into an agreement
relating to the Retained Properties  containing the same terms and conditions as
contained in the underlying agreements to which the Company is bound.

Section 6.16      New Areas of Mutual Interest.


(a)  Establishment.  The  Parties  hereby  establish  Areas of  Mutual  Interest
(individually,  an "AMI" and, collectively,  the "AMIs") consisting of all lands
within the boundaries  indicated on the plats attached as Exhibit E. The Parties
intend that these AMIs shall extend one mile beyond the exterior  boundaries  of
any oil and gas lease located within an AMI in which at least one of the Company
Parties  and  at  least  one  of the  Purchasers  both  have  an  interest,  and
accordingly  agree that the  boundaries  of these AMIs  shall  automatically  be
enlarged as new oil and gas leases within existing AMIs are acquired in which at
least  one of the  Company  Parties  and  one of the  Purchasers  both  have  an
interest,  so that this  intention is  continuously  fulfilled.  All AMIs hereby
established shall terminate on the fourth anniversary of the Closing Date.

         Notwithstanding anything to the contrary, if at any time the Purchasers
become bound by the provisions of the AMI Covenant of any Material Contract or
any agreement entered into after the Closing Date by and among one or more of
the Purchasers, one or more of the Company Parties and one or more third parties
(the "Applicable Third Party AMI Covenant"), then the AMIs created by this
Section 6.16(a) shall thereupon exclude all lands that are subject to the
Applicable Third Party AMI Covenant. The areas that are subject to Applicable
Third Party AMI Covenants at the date of this Agreement have been blacked out in
the plats attached as Exhibit E to indicate that the AMIs established by Section
6.16(a) do not apply to such lands.

(b) Procedure if Company Parties Acquire an Interest. If a Company Party
(including, for purposes of this Section 6.16(b), any Affiliate of a Company
Party) should acquire any interest (an "Interest") in any oil and gas lease or
other agreement authorizing the owner thereof to explore for, produce, save and
market oil and gas covering land within an AMI (including, without limitation,
farmout or other agreements by which oil and gas leasehold interests may be
earned), the Company Party shall first notify any person having a right to
acquire any portion of such Interest under an agreement identified in Schedule
4.03(a) and, after learning whether such person will be acquiring a portion of
such Interest, shall notify the Purchasers in writing of the acquisition of such
Interest. The notice shall set forth (a) the description of the Interest
acquired, (b) the pertinent terms of such acquisition, including copies of
leases, assignments, title data and any other agreement relating to the
acquisition of the Interest and the rights and obligations associated therewith,
(c) the Company Party's acquisition costs for that Interest, including, but not
limited to, lease brokerage fees, lease bonus, attorneys' fees for title
examination, and title curative costs, and (d) the portion of such Interest
being acquired by a person under an agreement identified in Schedule 4.03(a).
The Purchasers shall have the option to acquire 25% of the Interest that remains
(the "Remaining Interest") after a person has acquired (or has elected not to
acquire) a portion of that Interest under an agreement identified in Schedule
4.03(a), by paying its 25% share of the Company Party's acquisition costs and,
if the Purchasers do acquire 25% of the Remaining Interest, the Remaining
Interest will then be owned 75% by Pannonian (if in Utah or Wyoming) or San
Joaquin (if in California) and 25% by the Purchasers. In accordance with the
provisions of Section 1.03(f), the Purchasers may acquire up to an additional 5%
undivided interest in the Remaining Interest.

     The Purchasers shall have a period of thirty (30) days from receipt of such
notice to exercise such option by (a) giving the concerned  Company Party notice
in writing and (b) paying to the concerned Company Party, contemporaneously with
the notice,  their 25% share of the  acquisition  costs described in the notice.
Failure by the  Purchasers to respond within the  above-specified  30-day period
shall be deemed an election by the  Purchasers not to acquire their 25% share of
the Remaining Interest described in the said notice. Should the Purchasers elect
to acquire its interest,  such interest  shall be assigned free and clear of any
liens or burdens on production in excess of those  burdening the Interest on the
date it was acquired by the Company Party.  Assignments of working interests and
operating  rights in federal and state  leases  will be made on the  appropriate
government  assignment of operating rights, while assignments of fee leases will
be made on a form substantially similar to the form attached as Exhibit C-1. The
Purchasers  shall pay,  within thirty (30) days from receipt of an invoice,  its
25% share of the Company Party's acquisition costs for that Interest.

(c) Procedure if Purchasers Acquire an Interest. If a Purchaser (including,  for
purposes of this Section 6.16(c),  any Affiliate of a Purchaser)  should acquire
an Interest,  the Purchaser shall promptly notify  Pannonian (as to Interests in
Utah and Wyoming) or San Joaquin (as to Interests in  California)  in writing of
the acquisition of such Interest. The notice shall set forth (a) the description
of the Interest acquired, (b) the pertinent terms of such acquisition, including
copies of leases,  assignments,  title data and any other agreement  relating to
the  acquisition  of the  Interest  and the  rights and  obligations  associated
therewith,  and  (c)  the  Purchaser's  acquisition  costs  for  that  Interest,
including,  but not limited to, lease  brokerage fees,  lease bonus,  attorneys'
fees for title examination,  and title curative costs.  Pannonian or San Joaquin
shall have the option to acquire 70% of the Interest  acquired by the Purchaser,
proportionately reduced to the Interest acquired, by paying its 70% share of the
Purchaser's acquisition costs for that Interest,  including, but not limited to,
lease brokerage fees, lease bonus,  attorneys' fees for title  examination,  and
title curative costs.

     Pannonian  or San  Joaquin  shall  have a period of  thirty  (30) days from
receipt of such  notice to  exercise  such  option by (a)  giving the  concerned
Purchaser  notice in writing and (b) paying to the Purchaser,  contemporaneously
with the notice, its 70% share of the acquisition costs described in the notice.
Failure by Pannonian or San Joaquin to respond within the above-specified 30-day
period  shall be deemed an election by  Pannonian  or San Joaquin not to acquire
its  proportionate  part of the Interest  described  in the said notice.  Should
Pannonian or San Joaquin elect to acquire its interest,  such interest  shall be
assigned free and clear of any liens or burdens on production in excess of those
burdening the Interest on the date it was acquired by the Purchaser. Assignments
of working  interest  and  operating  rights in federal and state leases will be
made  on the  appropriate  government  assignment  of  operating  rights,  while
assignments  of fee leases will be made on a form  substantially  similar to the
form attached as Exhibit C-1.  Pannonian or San Joaquin shall pay, within thirty
(30)  days  from  receipt  of an  invoice,  its  70%  share  of the  Purchaser's
acquisition costs for that Interest.

(d) Operating Agreement.  If the Purchasers and either Pannonian (in the case of
Utah  and  Wyoming  properties)  or San  Joaquin  (in  the  case  of  California
properties)  both elect to participate in the  acquisition of an Interest,  then
they will be bound by any  Operating  Agreement to which the Interest is subject
or, if there is no Operating Agreement to which the Interest is subject, then to
the Operating Agreement attached hereto as Exhibit D; provided, however, that if
the  Interest  to be earned  under a farmout or other  earning  agreement  will,
pursuant to the terms of that farmout or earning agreement,  become subject to a
specified Operating  Agreement at some later date (for example,  where a farmout
agreement appends a form of operating  agreement that will become effective upon
payout of the earning  well),  then the  Purchasers and Pannonian or San Joaquin
hereby agree that they, as between  themselves,  will be subject to the terms of
the  specified  Operating  Agreement  from and after the date that both elect to
participate in the  acquisition of the concerned  Interest under that farmout or
earning agreement.

(e) Farmout and Earning Obligations. If any Remaining Interest is acquired under
Section 6.16(b) in the form of a farmout agreement, exploration agreement or any
other agreement that requires one or more wells to be drilled in order to earn a
leasehold interest, and if the Purchasers elect not to participate in an earning
well provided by such agreement through completion  (whether as a producer or as
a dry  hole)  for a full 30% of the  Parties'  aggregate  cost  share,  then the
Purchasers will forfeit any and all rights to receive any portion of the earning
well and leasehold  interests acquired as a result of drilling that earning well
(including,  without limitation,  rights to purchase additional interests in the
concerned  land under  Section  1.03(f)),  and will also  forfeit  all rights to
participate in subsequent earning wells under that agreement.  If the Purchasers
do participate in the drilling of an earning well for a full 30% of the Parties'
aggregate cost share,  then the Purchasers shall receive (i) 30% of the Parties'
aggregate  interest  in the  earning  well  and 30% of the  aggregate  leasehold
interest  earned by the  Parties in the  Designated  Wellbore  Area in which the
earning  well is located and (ii) an  undivided  25% of the  leasehold  interest
earned by the  Parties  in any  additional  acreage  by virtue of  drilling  the
earning well pursuant to the terms of the farmout or other earning agreement.

     Similarly, if any Interest is acquired under Section 6.16(c) in the form of
a farmout agreement,  exploration agreement or any other agreement that requires
one or more wells to be drilled in order to earn a  leasehold  interest,  and if
Pannonian (if in Utah or Wyoming) or San Joaquin elects not to participate in an
earning  well  provided  by such  agreement  through  completion  (whether  as a
producer or as a dry hole) for a full 70% of the Parties'  aggregate cost share,
then Pannonian or San Joaquin, as applicable, will forfeit any and all rights to
receive any portion of the earning well and  leasehold  interests  acquired as a
result of  drilling  that  earning  well,  and will also  forfeit  all rights to
participate in subsequent  earning wells under that  agreement.  If Pannonian or
San Joaquin does  participate  in the drilling of an earning well for a full 70%
of the  Parties'  aggregate  cost  share,  then  Pannonian  or San  Joaquin,  as
applicable,  shall receive 70% of the Parties' aggregate interest in the earning
well and 70% of the aggregate leasehold interest earned by the Parties by virtue
of  drilling  the  earning  well  pursuant  to the terms of the farmout or other
earning agreement.

(f) Not Binding on Non-Affiliates. The benefits and burdens of this Section 6.16
are  personal to the Company  Parties  and the  Purchasers,  as well as to their
respective Affiliates,  and consequently shall not run with the land. If a Party
participates in a merger or other corporate reorganization in which the survivor
is not an Affiliate of a Party,  then the  provisions of this Section 6.16 shall
not bind the non-Affiliated  survivor.  Similarly,  if a Party sells one or more
Interests  to a  third  party  who is not an  Affiliate  of a  Party,  then  the
provisions of this Section 6.16 shall not bind the non-Affiliated third party.

Section  6.17  Delay  Rentals  and  Minimum  Royalties.   Each  Party  shall  be
responsible  for  maintaining  and  monitoring  its own records  concerning  the
Leases,  Earning  Agreements,  and Interests (defined in Section 6.16), and each
Party will communicate with all other concerned  Parties  concerning the payment
status of delay  rentals  and minimum  royalties.  In no event will any Party be
liable for damages to any other Party if a Party fails to make a timely  payment
of any  necessary  delay  rental or  minimum  royalty  payment.  Subject  to the
foregoing  limitation  of  liability,  the Company  Parties  shall pay all delay
rentals  and  minimum  royalties  on  all  Additional  Interests  and  Remaining
Interests  the  Purchasers  may have a right to  purchase  until  such right has
extinguished  or legal title to such Additional  Interest or Remaining  Interest
has been conveyed to the Purchasers. If the Company intends to cease payments of
delay  rentals and minimum  royalties on an  Additional  Interest or a Remaining
Interest  that the  Purchasers  may have a right to purchase,  the Company shall
provide  the  Purchasers  with 30 days'  prior  notice of such  intention,  upon
receipt of which the Purchasers  shall have the right,  subject to the rights of
third parties to make such  payments and acquire  interests  thereby,  to assume
such  payments  and  require the Company to  transfer  such  interests,  without
warranty of title of any kind,  by providing  notice to the Company.  If a Party
does make a  necessary  delay  rental or  minimum  royalty  payment on behalf of
another  Party,  it will  furnish  the other  concerned  Party  with an  invoice
detailing  such other Party's  share of such payment,  and the other Party shall
pay such invoice within 30 days following receipt.  If the invoice is not timely
paid,  the Party seeking  payment shall send a second invoice to the other Party
and, if the other  Party  fails to pay the full amount of the invoice  within 14
days  after  the  date  of the  second  invoice,  then  the  other  Party  shall
conclusively be deemed to have  surrendered its interest in the concerned leases
and shall reassign its entire interest in those leases to the first Party,  free
and clear of all liens,  encumbrances and burdens, other than those in existence
at the date of this Agreement.

Section 6.18 Protested BLM Leases.  In February  2002, the Company  Parties paid
$1,428,436.75  (the "BLM Lease  Price") to the  Bureau of Land  Management  (the
"BLM") to  purchase  certain  federal  leases (the "BLM  Leases").  Prior to the
issuance of the BLM Leases,  a formal  protest of such issuance (the  "Protest")
was filed by one or more third  parties,  and as of the date of this  Agreement,
the BLM has not issued the BLM Leases and has not  refunded  the BLM Lease Price
to the Company Parties,  pending  resolution of the Protest.  The BLM Leases are
noted on Exhibit A as not issued and under protest. If the Protest is upheld and
the BLM Lease Price is refunded to the Company Parties, the Company Parties will
promptly  remit to the  Purchasers  by wire transfer  (pursuant to  instructions
provided by the Purchasers) 25% of the amount so refunded by the BLM (or 27 1/2%
or 30% of  such  amount  if the  Purchasers  have  acquired  part  or all of the
Additional Interest).  If the Purchasers make one or both Option Payments to the
Company  after the BLM Lease Price is refunded to the Company  Parties,  and the
foregoing payment is made to the Purchasers,  the Purchasers will be entitled to
deduct 2 1/2% of the  amount  of the BLM Lease  Price  refunded  to the  Company
Parties  from each such  Option  Payment.  If the  Protest is denied and the BLM
Leases are issued by the BLM,  the Company  Parties  will  promptly  execute and
deliver to the Purchasers assignments,  substantially in the form of the Closing
Assignment set forth in Exhibit C-1, of an undivided 25% of the Company Parties'
interest  in the BLM  Leases  (or an  undivided  27  1/2% or 30% of the  Company
Parties' interest,  as appropriate,  if the Purchasers have acquired part or all
of the Additional Interest).

Section 6.19 Financial Information.  The Company shall deliver to Brek financial
information  of the  Company  through  the  Closing  sufficiently  ahead  of the
deadline for filing reports with the SEC to permit Brek to prepare and file such
reports on a timely basis.  The Company shall  cooperate,  and use  commercially
reasonable efforts to cause its independent auditor to cooperate,  with Brek and
its independent auditor to allow Brek's independent auditor to review Brek's SEC
filings and to audit Brek's year-end financial  statements.  Should Brek wish to
make a filing with the SEC that requires the consent of the Company's present or
past independent auditor, the Company shall cooperate with such auditor for that
purpose and shall use commercially  reasonable  efforts to cause such consent to
be given.

Agreement;  and provided further that a termination  under Section 7.1(b) or (c)
shall not relieve any Party of any liability for breach of this Agreement or for
any misrepresentation hereunder as of the date of this Agreement or be deemed to
constitute   a   waiver   of  any   remedy   available   for  such   breach   or
misrepresentation.

Section 7.03 Survival.  The representations and warranties of the Parties hereto
contained in Sections 2.01, 2.02, 2.03, 2.06, 3.01, 3.02, 3.05, 4.01, 4.02, 4.03

survive the Closing indefinitely.  All the representations and warranties of the
Parties  hereto  contained in this Agreement and not referenced in the preceding
sentence and all claims, causes of action and damages with respect thereto shall
survive the Closing for a period of one year thereafter.

sufficiency of which are hereby acknowledged, Assignors hereby sell, assign, and
convey to Assignee, its successors and assigns, the following (collectively, the
"Assets"):

         An undivided 25% of Assignors' right, obligations, title and interest
         at the date of this Assignment in (i) the oil and gas leases described
         in Exhibit A, but only insofar as such leases cover the lands
         specifically described in Exhibit A (the "Leases"), and (ii) the rights
         and obligations of assignors, to the extent transferable, in and to all
         agreements described in Exhibit B (the "Contracts") and rights-of-way,
         easements and licenses, if any, that are appurtenant to or used in
         connection with the ownership or operation of the Leases, but only
         insofar as the Contracts and such rights-of-way, easements and licenses
         cover and pertain to the Leases.

         TO HAVE AND TO HOLD the Assets unto Assignee and its successors and
assigns forever, subject to the terms and conditions hereof.

         This Assignment is made and accepted expressly subject to the following
terms and conditions:

         (a) Assignors hereby reserve unto themselves, their successors and
assigns, the overriding royalty interest of production in the aggregate
described in the column headed "Reserved Overriding Royalty Interest" of Exhibit
A. If Assignors are assigning less than the full leasehold interest in a Lease
or if a Lease covers less than the full fee interest in the oil and gas estate,
then the overriding royalty interest herein reserved in the Lease shall be
reduced proportionately.

         (b) Subject to the Permitted Encumbrances (as such term is defined in
the Purchase Agreement), Assignors warrant title to the Assets only against the
claims of persons claiming by, through or under Assignors, but not otherwise.

         (c) Except as provided in subsection (a) above, the Assets are hereby
assigned by Assignors to Assignee without recourse, covenant or warranty of
title of any kind, express, implied or statutory. Any covenants or warranties
implied by statute or law by the use herein of the words "grant", "convey" or
other similar words are hereby expressly restrained, disclaimed, waived and
negated. The express representations and warranties of Assignors contained in
this Assignment are exclusive and are in lieu of all other representations and
warranties, express, implied or statutory. EXCEPT FOR THE EXPRESS
REPRESENTATIONS AND WARRANTIES OF ASSIGNORS MADE IN THE PURCHASE AGREEMENT,
ASSIGNEE ACKNOWLEDGES THAT ASSIGNORS HAVE NOT MADE, AND ASSIGNORS HEREBY
EXPRESSLY DISCLAIM AND NEGATE, AND ASSIGNEE HEREBY EXPRESSLY WAIVES, ANY
REPRESENTATION OR WARRANTY, EXPRESS, IMPLIED, AT COMMON LAW, BY STATUTE OR
OTHERWISE RELATING TO (a) THE QUALITY, QUANTITY OR VOLUME OF THE RESERVES OF
HYDROCARBONS, IF ANY, ATTRIBUTABLE TO THE ASSETS, (b) THE ACCURACY, COMPLETENESS
OR MATERIALITY OF ANY INFORMATION, DATA OR OTHER MATERIALS (WRITTEN OR ORAL)
NOW, HERETOFORE OR HEREAFTER FURNISHED TO ASSIGNEE BY OR ON BEHALF OF ASSIGNORS,
OR (c) THE ENVIRONMENTAL CONDITION OF THE ASSETS. ASSIGNORS AND ASSIGNEE AGREE
THAT, TO THE EXTENT REQUIRED BY APPLICABLE LAW TO BE EFFECTIVE, THE DISCLAIMERS
OF CERTAIN WARRANTIES CONTAINED IN THIS SECTION ARE "CONSPICUOUS" DISCLAIMERS
FOR THE PURPOSES OF ANY APPLICABLE LAW, RULE OR ORDER.

         (d) Assignee hereby assumes and agrees to pay, perform, fulfill and
discharge all claims, liabilities and obligations under the Leases and the
Contracts and under all Permitted Encumbrances, but only to the extent that any
of the foregoing are valid and enforceable, relate to the Assets and are
attributable to the period after the Effective Time.

         (e) Separate assignments of the Leases shall, as necessary, be executed
on officially approved forms (assignment of operating rights) by Assignors to
Assignee in sufficient counterparts to satisfy applicable statutory and
regulatory requirements. Those assignments shall be deemed to contain all of the
exceptions, reservations, rights, titles, powers, and privileges set forth
herein as fully as though they were set forth in each assignment. The interests
conveyed by such separate assignments are the same, and not in addition to, the
interest in the Leases conveyed herein. This Assignment, insofar as it affects
any interest in Leases the transfer of which must be approved by the Bureau of
Land Management or any state regulatory authority, is made and accepted subject
to the approval of the appropriate governmental agency and to the terms of such
approval, if and to the extent required by applicable law.

          (f)  To  facilitate  recording  or  filing  of  this  Assignment,  the
     counterpart  to be recorded in a given county may contain only that portion
     of the exhibits that describes Assets located in that county. Assignors and
     Assignee have each retained a counterpart of this  Assignment with complete
     exhibits.

          (g) Any  indivisible  right-of-way  or easement  is excluded  from the
     conveyance and grant made by this Assignment.

          (h) This  Assignment  binds and inures to the benefit of Assignors and
     Assignee and their respective successors and assigns.

          (i) This Assignment may be executed in any number of counterparts, and
     by  different  parties in  separate  counterparts,  each of which  shall be
     deemed  to be an  original  instrument,  but all of  which  together  shall
     constitute but one instrument.

         EXECUTED on the dates contained in the acknowledgment of this
instrument, but to be effective for all purposes as of the Effective Time.
