                                   The Loan

     Section 2.1     The Loan.

          (a)     Subject to the other terms and conditions of this Agreement,
USB agrees to: (1) make Advances to Borrower from time to time requested upon
written notice to USB from Borrower no later than noon, Denver time, at least
one Business Day prior to any Advance, and (2) issue Letters of Credit from
time to time requested upon written notice to USB from Borrower no later than
five Business Days prior to the date of issuance of such Letter of Credit.

          (b)     Each request by Borrower for an Advance shall be in the form
of Exhibit B attached hereto and made a part hereof.  Each request by Borrower
for the issuance or amendment of a Letter of Credit shall be in the form of
Exhibit C attached hereto and made a part hereof, and shall be accompanied by
an application for issuance or amendment of a letter of credit on USB's
then-standard form, duly executed by Borrower.

          (c)     USB shall not have any obligation to: (1) make an Advance on
or after the Maturity Date, (2) issue or renew a Letter of Credit which does
not expire prior to five Business Days before the Maturity Date, (3) make an
Advance in an amount less than $10,000, or (4) make an Advance or issue a
Letter of Credit if, after such Advance is made or such Letter of Credit is
issued, the aggregate amount of all Advances outstanding hereunder plus the
face amounts of all Letters of Credit outstanding hereunder would exceed the
Commitment Amount.

          (d)     Each payment by USB under a Letter of Credit shall be deemed
to be an Advance, bearing interest from the date of such payment.  Each
payment by USB under a Letter of Credit shall be a demand obligation owing by
Borrower to USB, bearing interest from the date of such payment at the rate
described in Section 2.2(b)(2) below.  Each payment by USB under any Letter of
Credit shall be entitled to all benefits of the Security Documents and shall
be subject to all terms of this Agreement and any and all other applicable
Loan Documents.

                                      7

<PAGE>
          (e)     Within the limitation of the Commitment Amount and subject
to the other terms and provisions hereof, Borrower may borrow, repay and
reborrow hereunder.  The Advances, Letters of Credit and demand obligations
described above shall be herein collectively referred to as the "Loan".
Borrower hereby expressly requests and irrevocably authorizes USB to make the
Loan.

     Section 2.2     The Note; Interest.

          (a)     Borrower's obligation to repay the Loan, with interest
thereon, shall be evidenced by the Note.  In the event any provision contained
in the Note conflicts with a provision contained in this Agreement, the
provisions of this Agreement shall control.

          (b)     (1)  Except as otherwise provided in (2) below, interest on
the Loan shall accrue at a fluctuating annual rate equal to the Prime Rate
plus one percentage point per annum.  (2)  From and after the occurrence, and
during the continuance, of any Event of Default hereunder (including without
limitation any failure by Borrower to pay the entire outstanding principal
balance of the Loan, together with all accrued interest, fees and other
amounts payable in connection therewith, on or before the Maturity Date),
interest on the Loan shall accrue, from the date of occurrence of the Event of
Default until the date the Event of Default is cured, at a fluctuating annual
rate equal to the Prime Rate plus five percentage points per annum.

          (c)     Interest accrued on the Loan shall be due and payable on
each Payment Date.  All accrued and unpaid interest shall be due and payable
not later than the Maturity Date.

     Section 2.3     Mandatory Principal Payments.

          (a)     If for any reason the aggregate outstanding principal
balance of all Advances plus the aggregate face amount of all outstanding
Letters of Credit shall exceed the Commitment Amount, Borrower shall, after
written notice thereof from USB: (1) pay the excess to USB in a lump sum
within 10 days after such notice; or (2) commence, as of the last day of the
calendar month in which such notice is given (and thereafter continue), an
amortization schedule under which Borrower repays the Loan in an amount at
least equal to the excess in six equal monthly principal installments on the
last day of each calendar month, which amounts shall be in addition to the
monthly interest payments and any other principal payments otherwise due, such
that the entire excess is paid within six months; or (3) within 10 days after
such notice, execute and deliver to USB additional mortgages, supplements to
mortgages or other instruments in form and substance reasonably satisfactory
to USB, by which Borrower mortgages, pledges or hypothecates to USB, or
creates a security interest in for the benefit of USB, sufficient additional
Oil and Gas Interests to induce USB to make a redetermination of the Borrowing
Base such that the Commitment Amount is increased to an amount no less than
the aggregate outstanding principal balance of all Advances plus the sum of
the face amounts of all outstanding Letters of Credit.

          (b)     Any and all payments made by USB under any Letter of Credit
shall be repaid by Borrower to USB immediately after USB demands payment
thereof.

          (c)     The outstanding principal balance of all Advances, together
with all unpaid fees and expenses, shall be due and payable not later than the
Maturity Date.


                                      8

     Section 2.4     Voluntary Prepayments.  Borrower shall have the right to
prepay any or all Advances at any time, in whole or in part, without penalty
or premium.

     Section 2.5     Termination of Agreement.  Borrower shall have the right
at any time and from time to time, upon not less than three Business Days'
prior written notice to USB, to terminate this Agreement.  Upon any
termination of this Agreement, Borrower shall, at the time of such
termination, prepay the Note in full and cause any and all outstanding Letters
of Credit to be terminated and USB released from any liability thereunder.
Any such prepayment shall be without penalty or premium.

     Section 2.6     Payments to USB.  Borrower will pay to USB each payment
which Borrower owes under the Loan Documents not later than 12:00 noon, Denver
time, on the due date, in lawful money of the United States of America and in
immediately available funds.  Any payment received after such time will be
deemed to have been made on the next following Business Day.  Should any such
payment become due and payable on a day other than a Business Day, the
maturity of such payment shall be extended to the next succeeding Business
Day, and, in the case of a payment of principal or past due interest, interest
shall accrue and be due and payable thereon for the period of such extension.
Each payment under a Loan Document shall be due and payable at the place
provided therein or, if no specific place of payment is provided, shall be due
and payable at the place of payment of the Note.

     Section 2.7     Use of Proceeds.  In no event shall the Loan proceeds be
used directly or indirectly for the purpose, whether immediate, incidental or
ultimate, of purchasing, acquiring or carrying any "margin stock" (as such
term is defined in Regulation U promulgated by the Board of Governors of the
Federal Reserve System) or to extend credit to others directly or indirectly
for the purpose of purchasing or carrying any such margin stock.  Borrower
represents and warrants to USB that Borrower is not engaged principally, or as
one of its important activities, in the business of extending credit to others
for the purpose of purchasing or carrying such margin stock.  Borrower will
use the Loan and the Loan proceeds solely to repay, on behalf of Guarantor,
the outstanding balance of the Petrobridge Indebtedness, to repay, on behalf
of Guarantor, the outstanding balance of the Kansas City Indebtedness, to fund
capital expenditures relating to the acquisition, exploration or development
of oil and gas properties, to fund Borrower's general working capital needs
and for the issuance of Letters of Credit in connection with Borrower's
business.

     Section 2.8     Borrowing Base Procedures.  The Borrowing Base will be
redetermined by USB as of the first day of each Borrowing Base Period (and not
more than one additional time per calendar year as requested by Borrower and
not more than one additional time per calendar year as requested by USB),
based upon the engineering reports and other information submitted by Borrower
pursuant to Section 6.1(b) below and upon such other information and data as
USB reasonably deems relevant.  USB shall advise Borrower of each
redetermination of the Borrowing Base by providing to Borrower a Borrowing
Base Notice as of the date of effectiveness of the redetermined Borrowing
Base; provided that if, due to any failure by Borrower to submit in a timely
manner any engineering report or other information required to be submitted by
Borrower hereunder or, if requested in writing by USB, any additional
information or data needed in connection with a redetermination of the
Borrowing Base or due to any other reason beyond the control of USB, USB does
not provide a Borrowing Base Notice at the time described above, then, unless
USB gives notice to the contrary to Borrower, the Borrowing Base from the


                                      9

<PAGE>
previous period shall be carried over into the new period until a Borrowing
Base Notice has been sent to Borrower by USB.  Borrower shall have the right
from time to time, by giving at least three Business Days' prior notice to
USB, to elect to reduce the Borrowing Base by any integral multiple of
$100,000; provided that no such reduction shall reduce the Borrowing Base to
an amount less than $2,000,000; provided further that, as to any time period
for which Borrower has so elected to reduce the Borrowing Base, the reduced
Borrowing Base shall remain in effect until the next redetermination of the
Borrowing Base hereunder (or, if sooner, the next election by Borrower to
reduce the Borrowing Base pursuant to this Section).

                                  ARTICLE III
                                Security; Fees

     Section 3.1     The Security.  The Obligations will be secured by the
Security Documents executed and delivered contemporaneously herewith and any
additional Security Documents hereafter delivered by any Obligated Person and
accepted by USB.

     Section 3.2     Perfection and Protection of Security Interests and
Liens.  Borrower will from time to time deliver to USB any amendments,
financing statements, continuation statements, extension agreements and other
documents, properly completed and executed (and acknowledged when required) by
Borrower in form and substance reasonably satisfactory to USB, which USB may
request for the purpose of perfecting, confirming or protecting USB's Liens
and other rights in the Collateral.

     Section 3.3     Bank Accounts and Offset.  Borrower will establish,
within 90 days of the date of this Agreement, and will thereafter maintain,
until this Agreement has been terminated and any and all amounts payable by
Borrower hereunder have been repaid in full, at USB, Borrower's primary
depositary account, into which account Borrower will deposit or cause to be
deposited any and all proceeds of production received by Borrower from the
Collateral.  To secure the repayment of the Obligations, Borrower hereby
grants to USB a security interest, a lien, and a right of offset, each of
which shall be upon and against: (a) any and all moneys, securities or other
property (and the proceeds therefrom) of Borrower now or hereafter held or
received by or in transit to USB from or for the account of Borrower, whether
for safekeeping, custody, pledge, transmission, collection or otherwise, (b)
any and all deposits (general or special, time or demand, provisional or
final) of Borrower with USB, and (c) any other credits and claims of Borrower
at any time existing against USB, including without limitation claims under
certificates of deposit.  Upon the occurrence of any Event of Default, USB is
hereby authorized to foreclose upon, offset, appropriate and apply, at any
time and from time to time, without notice to Borrower, any and all items
hereinabove referred to against the Obligations (whether or not such
Obligations are then due and payable).

     Section 3.4     Fees.

          (a)     Borrower shall pay to USB, for the time period commencing on
the date hereof through the Maturity Date, within 30 days after the end of
each calendar quarter prior to the Maturity Date, commencing with the calendar
quarter ending September 30, 2003, and on the Maturity Date, for the time
period from the end of the last such calendar quarter through the Maturity
Date, a commitment fee in an amount equal to one-half of one percent per
annum, times the excess, if any, of: (1) the Commitment Amount, over (2) the
sum of the aggregate outstanding principal balance of all Advances plus the
face amounts of all outstanding Letters of Credit, computed on a daily basis
for such calendar quarter or other time period.

                                      10

<PAGE>
          (b)     Borrower shall pay to USB with respect to each Letter of
Credit a fee in an amount equal to the greater of: (1) $500.00, or (2) one and
one-half percent per annum times the face amount of such Letter of Credit,
which fee shall be due and payable at the time of issuance (and again at the
time of any renewal) of such Letter of Credit.

          (c)     Borrower shall pay to USB, at the time of the execution and
delivery of this Agreement, a facility fee in the amount of $110,000.

          (d)     Borrower shall pay to USB, within 30 days after the
effective date of each of the Borrowing Base redeterminations scheduled for
July 1, 2004 and July 1, 2005, a loan fee in the amount of: (1) one-half of
one percent, times (2) the Commitment Amount in effect immediately after each
of the above-described redeterminations.

          (e)     Contemporaneously with any and all increases in the Maximum
Loan Amount hereafter requested by Borrower and agreed to by USB, Borrower
shall pay to USB a facility fee in an amount equal to two percent times the
amount by which the Maximum Loan Amount is being increased in excess of the
greater of: (1) $5,500,000 or (2) the highest Maximum Loan Amount as to which
the fee pursuant to this Section 3.4(e) has previously been paid.

     Section 3.5     Obligations Absolute.  The obligation of Borrower to
repay any amount drawn on USB pursuant to the terms of a Letter of Credit
shall be absolute, unconditional and irrevocable, and shall be performed
strictly in accordance with the terms of this Agreement, under all
circumstances whatsoever, including without limitation the following
circumstances:

          (a)     The existence of any claim, set-off, defense or other right
which Borrower may have at any time against any beneficiary of a Letter of
Credit (or any Person for whom any such beneficiary may be acting) or any
other Person, whether in connection with this Agreement, the transactions
contemplated hereby or any unrelated transactions;

          (b)     Any statement or any other document presented under any
Letter of Credit proving to be forged, fraudulent, invalid or insufficient in
any respect or any statement therein being untrue or inaccurate in any respect
whatsoever; or

          (c)     Payment by USB under any Letter of Credit against
presentation of a draft or certificate which does not comply in all material
respects with the terms of such Letter of Credit.

Payment by Borrower of a reimbursement obligation in connection with a Letter
of Credit issued pursuant to this Agreement shall not be deemed a waiver of
any rights of Borrower against USB under Section 3.7(d) below.

     Section 3.6     Indemnification.  Borrower hereby indemnifies and agrees
to hold harmless USB from and against any and all claims, damages, losses,
liabilities, costs or expenses whatsoever which USB may incur (or which may be
claimed against USB by any Person) by reason of or in connection with the
execution and delivery or transfer of or payment or failure to pay under any
Letter of Credit; provided, however, that Borrower shall not be required to
indemnify USB for any claims, damages, losses, liabilities, costs or expenses
to the extent, but only to the extent, caused by the willful misconduct or
gross negligence of USB in connection with paying a draft presented under a
Letter of Credit or by the breach of USB's obligations under any Loan Document
if such breach arises by reason of the willful misconduct or gross negligence
of USB.  Nothing in this Section 3.6 is intended to limit the obligation of
Borrower to repay any amount drawn on USB pursuant to the terms of a Letter of
Credit.
                                      11

     Section 3.7     Liability of USB.  Borrower assumes all risks of the acts
or omissions of any beneficiary or permitted transferee of any Letter of
Credit with respect to its use of such Letter of Credit.  Neither USB nor any
of its employees, officers or directors shall be liable or responsible for:

          (a)     The use which may be made of any Letter of Credit or for any
acts or omissions of any beneficiary or transferee thereof in connection
therewith;

          (b)     The validity, sufficiency or genuineness of documents, or of

not comply with the terms of the applicable Letter of Credit, including
failure of any documents to bear any reference or adequate reference to the
applicable Letter of Credit; or

          (d)     Any other circumstance whatsoever in making or failing to
make payment under the Letter of Credit, except only that Borrower shall have
a claim against USB, and USB shall be liable to Borrower, to the extent, but
only to the extent, of any direct (as opposed to consequential) damages
suffered by Borrower which were caused by:

               (1)     USB's willful misconduct, bad faith or gross
     negligence in connection with the Letter of Credit;

               (2)     USB's bad-faith or grossly negligent failure to pay
     under any Letter of Credit after the presentation to it by the
     beneficiary of a draft and certificate strictly complying with the terms
     and conditions of such Letter of Credit; or

               (3)     USB's breach of its obligations under any Loan
     Document if such breach arises from the willful misconduct or gross
     negligence of USB.

                       Representations and Warranties

     Section 5.1     Borrower's Representations and Warranties.  To induce USB
to enter into this Agreement and to make the Loan, Borrower represents and
warrants to USB (which representations and warranties shall survive the
delivery of the Note and shall be deemed to be continuing representations and
warranties until repayment in full of the Note) that:

          (a)     No Default.  Borrower is not in default in any material
respect in the performance of any of the covenants and agreements contained
herein.  No event has occurred and is continuing which constitutes a Default.

          (b)     Organization and Good Standing.  Borrower is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Wyoming, having all powers required to carry on its business and
enter into and carry out the transactions contemplated hereby.  Borrower is
duly qualified, in good standing and authorized to do business in all other
jurisdictions wherein the character of the properties owned or held by it or
the nature of the business transacted by it makes such qualification
necessary, unless the failure so to qualify would not reasonably be expected
to have a material adverse effect on Borrower.

          (c)     Authorization.  Borrower has duly taken all action necessary
to authorize the execution and delivery by it of the Loan Documents and to
authorize the consummation of the transactions contemplated thereby and the
performance of its obligations thereunder.

          (d)     No Conflicts or Consents.  The execution and delivery by the
various Obligated Persons of the Loan Documents to which each is a party, the
performance by each of its obligations under such Loan Documents, and the
consummation of the transactions contemplated by the various Loan Documents,
do not and will not: (1) conflict with any provision of: (A) any domestic or
foreign law, statute, rule or regulation, (B) the governing documents of
Borrower, or (C) any agreement, judgment, license, order or permit applicable
to or binding upon any Obligated Person, unless such conflict would not
reasonably be expected to have a material adverse effect on Borrower, (2)
result in the acceleration of any indebtedness owed by any Obligated Person,
or (3) result in or require the creation of any Lien upon any assets or
properties of any Obligated Person except as expressly contemplated by the
Loan Documents.  Except as expressly contemplated by the Loan Documents, no
consent, approval, authorization or order of, and no notice to or filing with,
any court or governmental authority or third party is required in connection
with the execution, delivery or performance by any Obligated Person of any
Loan Document or to consummate any transactions contemplated by the Loan
Documents.

          (e)     Enforceable Obligations.  This Agreement is, and the other
Loan Documents when duly executed and delivered will be, legal and binding
obligations of each Obligated Person which is a party hereto or thereto,
enforceable in accordance with their respective terms, except as limited by
bankruptcy, insolvency or similar laws of general application relating to the
enforcement of creditors' rights and as limited by general equitable
principles.

          (f)     Initial Financial Statements.  Except for the Liabilities
incurred pursuant to the Petrobridge Credit Agreement, the Initial Financial




                                      14

<PAGE>
Statements fairly present in all material respects Borrower's and Guarantor's
respective financial positions at the dates thereof.  Since the dates of the
Initial Financial Statements, no material adverse change has occurred in
Borrower's or Guarantor's financial condition or business.  The Initial
Financial Statements of Borrower and Guarantor were prepared in accordance
with GAAP.

          (g)     Other Obligations.  Except for the Liabilities incurred
pursuant to the Petrobridge Credit Agreement, Borrower has no material
outstanding Liabilities of any kind (including contingent obligations, tax
assessments and unusual forward or long-term commitments) which are not shown
in the Initial Financial Statements.

          (h)     Full Disclosure.  No certificate, statement or other
information delivered herewith or heretofore by Borrower to USB in connection
with the negotiation of this Agreement or in connection with any transaction
contemplated hereby contains any untrue statement of a material fact or omits
to state any material fact known to Borrower necessary to make the statements
contained herein or therein not misleading in any material respect as of the
date made or deemed made.  At the date of this Agreement, Borrower is not
aware of any material fact that has not been disclosed to USB in writing which
could materially and adversely affect Borrower's properties, businesses or
condition (financial or otherwise).  The copies of the Initial Engineering
Reports heretofore furnished by Borrower to USB are true and correct copies of
such reports.  To Borrower's knowledge, the Initial Engineering Reports, as of
their dates, were based upon complete and accurate factual information in all
material respects, it being understood that the Initial Engineering Reports
are necessarily based upon professional opinions, estimates and projections
and that Borrower does not warrant that such opinions, estimates and
projections will ultimately prove to have been accurate.

          (i)     Litigation.  Except as disclosed in the Initial Financial
Statements or as otherwise disclosed in writing by Borrower to USB prior to
the date hereof:  (1) there are no actions, suits or legal, equitable,
arbitrative or administrative proceedings pending, or to the knowledge of
Borrower threatened, against any Obligated Person before any federal, state,
municipal or other court, department, commission, body, board, bureau, agency
or instrumentality, domestic or foreign, which do or may materially and
adversely affect any Obligated Person, any Affiliate of any Obligated Person,
any Obligated Person's ownership or use of any of its assets or properties,
its business or financial condition, or the right or ability of any Obligated
Person to enter into the Loan Documents or perform its obligations thereunder
and (2) there are no outstanding judgments, injunctions, writs, rulings or
orders by any such governmental entity against any Obligated Person which have
or would reasonably be expected to have any such effect.

          (j)     Title to Properties.  Subject to typical oil-industry
operating agreements and product-purchase contracts and except as heretofore
disclosed by Borrower to USB in writing: (1) Borrower has good and defensible
title to the Borrowing Base Properties, free and clear of all liens,
encumbrances and defects of title, except for covenants, restrictions, rights,
easements, liens, encumbrances and minor irregularities in title which do not
materially interfere with the occupation, use and enjoyment of such Borrowing
Base Properties in the normal course of business as presently conducted or
materially impair the value thereof for such business, (2) Borrower enjoys
peaceful and undisturbed possession under all material leases under which
Borrower operates with respect to the Borrowing Base Properties, and (3) all
such leases are valid and subsisting, with no material default existing
thereunder.

          (k)     Place of Business.  The chief executive office and principal
place of business of Borrower are located at the address of Borrower set out
in Section 8.3 below.

          (l)     Taxes.  All tax returns required to be filed by Borrower in
any jurisdiction prior to the date hereof have been filed; all taxes,
assessments, fees and other governmental charges upon Borrower or upon any of
Borrower's properties, income or franchises, which are due and payable have
been paid, or adequate reserves have been provided for payment thereof.

          (m)     Use of Proceeds.  Borrower is not engaged principally, or as
one of its important activities, in the business of extending credit for the
purpose of purchasing or carrying margin stock (within the meaning of
Regulation U or X of the Board of Governors of the Federal Reserve System),
and no part of the proceeds of the Loan will be used to purchase or carry any
such margin stock or to extend credit to any Person for the purpose of
purchasing or carrying any such margin stock.  Neither Borrower nor any Person
acting on Borrower's behalf has taken or will take any action which might
cause this Agreement or the Note or the application of the proceeds of the
Loan to violate either of said Regulations U or X or any other regulation of
the Board of Governors of the Federal Reserve System or to violate the
Securities Exchange Act of 1934, in each case as now in effect or as the same
may hereafter be in effect.  Borrower will use the Loan and the Loan proceeds
solely to repay, on behalf of Guarantor, the outstanding balance of the
Petrobridge Indebtedness, to repay, on behalf of Guarantor, the outstanding
balance of the Kansas City Indebtedness, to fund capital expenditures relating
to the acquisition, exploration or development of oil and gas properties, to
fund Borrower's general working capital needs and for the issuance of Letters
of Credit in connection with Borrower's business.

          (n)     Investment Company Act Not Applicable.  Borrower is not an
"investment company" or a person "controlled" by an "investment company"
within the meaning of the Investment Company Act of 1940, as amended.

          (o)     Public Utility Holding Company Act Not Applicable.  Borrower
is not a "holding company," or a "subsidiary company" of a "holding company,"
or an "affiliate" of a "holding company," or of a "subsidiary company" of a
"holding company" as such terms are defined in the Public Utility Holding
Company Act of 1935, as amended.

          (p)     ERISA Liabilities.  All currently existing ERISA Plans have
been disclosed in writing by Borrower to USB.  Except as disclosed in the
Initial Financial Statements, no Termination Event has occurred with respect
to any ERISA Plan, and the Obligated Persons and all ERISA Plans are in
compliance with ERISA in all material respects.  No act, omission or
transaction has occurred which could result in the imposition on any Obligated
Person or any ERISA Affiliate (whether directly or indirectly) of a civil
penalty assessed pursuant to any of subsections (c), (i) or (l) of Section 502
of ERISA, a tax imposed pursuant to Chapter 43 of Subtitle D of the Code or a
breach of fiduciary duty liability damages under Section 409 of ERISA.  No
ERISA Plan (other than a defined contribution plan) or any trust created under
any ERISA Plan has been terminated since September 2, 1974.  No liability to
the Pension Benefit Guaranty Corporation (other than for the payment of
current premiums that are not past due) by any Obligated Person or any ERISA
Affiliate has been or is expected by any Obligated Person or any ERISA
Affiliate to be incurred with respect to any ERISA Plan.  No Obligated Person
is required to contribute to, or has any other absolute or contingent
liability in respect of, any multiemployer plan (as defined in Section 4001 of
ERISA).  Except as set forth in the Initial Financial Statements: (1) the


                                      16

<PAGE>
Obligated Persons and the ERISA Affiliates have made full payment of any and
all amounts required to be paid under the terms of each ERISA Plan or
applicable law, and no accumulated funding deficiency (as defined in Section
302 of ERISA or Section 412 of the Code) exists with respect to any ERISA
Plan, whether or not waived by the Secretary of the Treasury or his delegate,
and (2) the actuarial present value of each ERISA Plan's benefit liabilities
(as defined in Section 4041 of ERISA) does not exceed the current value of
such ERISA Plan's assets (computed on a plan termination basis in accordance
with Title IV of ERISA) available for the payment of such benefits.  Neither
any Obligated Person nor any ERISA Affiliate sponsors, maintains or
contributes to an employee welfare benefit plan (as defined in Section 3(l) of
ERISA), including without limitation any such plan maintained to provide
benefits to former employees of such entities, that may not be terminated by
such Obligated Person or ERISA Affiliate in its sole discretion at any time
without material liability.  Neither any Obligated Person nor any ERISA
Affiliate is required to provide security under Section 401(a)(29) of the Code
because of an amendment to an ERISA Plan that results in an increase in
current liability for such ERISA Plan.

     Section 5.2     Representations by USB.  USB hereby represents that it
will acquire the Note for its own account in the ordinary course of its
commercial banking business; however, the disposition of USB's property shall
at all times be and remain within its control and this section does not
prohibit USB's sale of the Note or of any participation in the Note to any
bank, financial institution, investor or other purchaser.

                                  ARTICLE VI

     Year;

               (c)     Other Information and Inspections.  Each Obligated
     Person will furnish to USB any information which USB may from time to
     time request concerning any covenant, provision or condition of the Loan
     Documents or any matter in connection with the Obligated Persons'
     businesses and operations.  Each Obligated Person will permit
     representatives appointed by USB, including independent accountants,
     agents, attorneys, appraisers and any other persons, to visit and
     inspect, upon reasonable prior notice, at their sole risk, any of such
     Obligated Person's property, including its books of account, other books
     and records, and any facilities or other business assets, and to make
     extra copies therefrom and photocopies and photographs thereof, and to
     write down and record any information such representatives obtain, and
     each Obligated Person shall permit USB or its representatives to

     Obligated Person or of any default by any Obligated Person under any
     indenture, mortgage, material agreement, material contract or other
     material instrument to which any of them is a party or by which any of
     them or any of their properties is bound, if such default could
     reasonably be expected to have a material adverse effect upon such
     Obligated Person or such properties, (4) of the receipt of any uninsured
     written claim of $100,000 or more arising from any alleged breach of
     contract or tortious action or inaction by any Obligated Person, (5) of
     the filing of any suit or proceeding against any Obligated Person (or
     the occurrence of any material development in any such suit or
     proceeding) in which an adverse decision could have a material adverse
     effect upon any Obligated Person's financial condition, business or
     operations (or would reasonably be expected to result in a judgment not
     covered by insurance of $100,000 or more against any Obligated Person),
     (6) of the merger or consolidation of Borrower with any other business
     entity or the formation, acquisition or funding of any new subsidiary of

     occurrence of any of the foregoing, the Obligated Persons will take all
     necessary or appropriate steps to remedy promptly any such material
     adverse change, Default, or default, to protect against any such adverse
     claim, to defend any such suit or proceeding, and to resolve all
     controversies on account of any of the foregoing.  Borrower will also
     notify USB in writing at least twenty Business Days prior to the date
     that Borrower changes its name, the state under the laws of which it is
     organized, the location of its chief executive office or principal place

maintain and preserve its existence and its rights and franchises in full

on Borrower.

          (f)     Maintenance of Properties.  Borrower will in all material
respects maintain, preserve, protect and keep the Collateral and the Borrowing
Base Properties in accordance with the standards of a reasonable and prudent

material respects, when due, all other Liabilities not subject to any

Person may, however, delay paying or discharging any such Liability so long as
it is in good faith contesting the validity thereof by appropriate action and,
if required under GAAP, has set aside on its books adequate reserves therefor.

          (h)     Insurance.  Borrower will maintain with financially sound
and reputable insurance companies, insurance with respect to its business,
operations and properties in at least such amounts and against at least such

instruments relating thereto, (2) the filing, recording, refiling and
re-recording of any Security Documents and any other documents or instruments
or further assurances required to be filed or recorded or refiled or

occurrence of a Default or an Event of Default, of the Loan Documents.

          (j)     Performance on Borrower's Behalf. If any Obligated Person
fails to pay any taxes, insurance premiums or other amounts it is required to
pay under any Loan Document, USB may pay the same.  Borrower shall immediately
reimburse USB for any such payments and each amount paid shall constitute a
part of the Obligations, shall be secured by the Security Documents and shall
bear interest at the rate described in Section 2.2(b)(2) above from the date
such amount is paid by USB until the date such amount is repaid to USB.

          (k)     Compliance with Agreements and Law.  Borrower will perform
all material obligations it is required to perform under the terms of each
indenture, mortgage, deed of trust, security agreement, lease, franchise,


                                      20

<PAGE>
agreement, contract or other instrument or obligation to which it is a party
or by which it or any of its properties is bound in such a way that they
result in no material adverse effect upon any of the Borrowing Base Properties
or Borrower's ability to perform its obligations under this Agreement.
Borrower will in all material respects conduct its business and affairs in
compliance with all laws, regulations, and orders applicable thereto
(including those relating to pollution and other environmental matters).

          (l)     Certifications of Compliance.  Each Obligated Person will
furnish to USB at such Obligated Person's or Borrower's expense all
certifications which USB from time to time reasonably requests, as to the
accuracy and validity of or compliance with all representations, warranties
and covenants made by any Obligated Person in the Loan Documents, the
satisfaction of all conditions contained therein, and all other matters
pertaining thereto.

          (m)     Additional Security Documents.  Promptly after a request
therefor by USB at any time and from time to time, Borrower will execute and
deliver to USB such additional Security Documents and/or amendments to
existing Security Documents as USB may deem necessary or appropriate in order
to grant to USB a perfected lien on and security interest in any or all
Borrowing Base Properties owned by Borrower.

          (n)     Subsidiaries.  If Borrower hereafter forms, acquires or
funds any subsidiary, Borrower shall promptly cause such subsidiary to become
an Obligated Person by executing and delivering to USB such Loan Documents as
may be required by USB, in form and substance reasonably satisfactory to USB.

          (o)     ERISA Compliance.  Each Obligated Person will: (1) make

United States District Court of a trustee to administer such ERISA Plans,
together with a statement, if requested by USB, as to the reason therefor and
the action, if any, proposed to be taken with respect thereto.

at such time, the then-current best estimates of such tax rate or taxable
income; provided that when the actual tax rate and taxable income are

(2) any such failure with respect to a covenant, agreement, condition or
provision contained in Section 6.2 above, Borrower shall have a 30-day grace

          (d)     Any representation or warranty previously, presently or
hereafter made in writing by or on behalf of any Obligated Person in
connection with any Loan Document shall prove to have been false or incorrect

     assets or any part of the Borrowing Base Properties; or makes a general
     assignment for the benefit of creditors; or fails generally to pay (or
     admits in writing its inability to pay) its debts as such debts become
     due; or takes action in furtherance of any of the foregoing; or

               (4)     suffers the entry against it of a final judgment for
     the payment of money in excess of $100,000 (not covered by insurance),

ERISA Plan, whether or not waived by the Secretary of the Treasury or his

of such benefit liabilities by more than $100,000 (or in the case of a
Termination Event involving the withdrawal of a substantial employer, the
withdrawing employer's proportionate share of such excess exceeds such
amount); or

          (g)     Any default, after the expiration of any applicable period
of grace, occurs with respect to any other indebtedness owed by Borrower to

          (i)     The Guaranty ceases to be in full force and effect and
applicable to any and all of the Obligations covered thereby in accordance

Upon the occurrence of an Event of Default described in subsection (e)(1),
(e)(2) or (e)(3) of this section, all of the Obligations shall thereupon be
immediately due and payable, without presentment, demand, protest, notice of
protest, declaration or notice of acceleration or intention to accelerate, or
any other notice or declaration of any kind, all of which are hereby expressly
waived by Borrower.  During the continuance of any other Event of Default, USB
at any time and from time to time (unless all Events of Default have
theretofore been remedied) may declare any or all of the Obligations
immediately due and payable, and all such Obligations shall thereupon be
immediately due and payable.

     Section 7.2     Remedies.  If any Default or Event of Default shall occur
and be continuing, the obligation of USB to make Advances under this Agreement
shall terminate immediately.  If any Event of Default shall occur, USB may
protect and enforce its rights under the Loan Documents by any appropriate
proceedings, including proceedings for specific performance of any covenant or
agreement contained in any Loan Document, and USB may enforce the payment of
any Obligations due or enforce any other legal or equitable right.  All
rights, remedies and powers conferred upon USB under the Loan Documents shall
be deemed cumulative and not exclusive of any other rights, remedies or powers
available under the Loan Documents or at law or in equity.

     Section 7.3     Indemnity.  Borrower hereby agrees to indemnify, defend
and hold harmless USB and its agents, affiliates, officers, directors and
employees from and against any and all claims, losses, demands, actions,
causes of action and liabilities whatsoever (including without limitation
reasonable attorneys' fees and expenses, and costs and expenses reasonably
incurred in investigating, preparing or defending against any litigation or
claim, action, suit, proceeding or demand of any kind or character) arising
out of or resulting from:  (a) the Loan Documents (including without
limitation the enforcement thereof), except to the extent such claims, losses
and liabilities are proximately caused by USB's gross negligence, willful


                                      27

<PAGE>
misconduct or violation of its obligations under any of the Loan Documents,

substance or environmental pollutant, or (c) the violation of any federal,
state or local environmental statute, rule, regulation or ordinance, including
without limitation violation of the Comprehensive Environmental Response,

Resource Conservation and Recovery Act, as amended from time to time.
Borrower's obligations under this Section 7.3 shall survive the termination of
this Agreement.

                                Miscellaneous

     Section 8.1     Waiver and Amendment.  No failure or delay by USB in
exercising any right, power or remedy which it may have under any of the Loan
Documents shall operate as a waiver thereof or of any other right, power or
remedy, nor shall any single or partial exercise by USB of any such right,
power or remedy preclude any other or further exercise thereof or of any other
right, power or remedy.  No waiver of any provision of any Loan Document and
no consent to any departure therefrom shall ever be effective unless it is in
writing and signed by USB, and then such waiver or consent shall be effective
only in the specific instances and for the purposes for which given and to the
extent specified in such writing.  No notice to or demand on any Obligated
Person shall in any case of itself entitle any Obligated Person to any other
or further notice or demand in similar or other circumstances.  No
modification or amendment of or supplement to this Agreement or the other Loan
Documents shall be valid or effective unless the same is in writing and signed
by the party against whom it is sought to be enforced.

     Section 8.2     Survival of Agreements; Cumulative Nature.  All of the
Obligated Persons' various representations, warranties, covenants and
agreements in the Loan Documents shall survive the execution and delivery of
this Agreement and the other Loan Documents and the performance hereof and
thereof, including without limitation the making or granting of the Loan and
the delivery of the Note and the other Loan Documents, and shall further
survive until all of the Obligations are paid in full to USB and all of USB's
obligations to Borrower are terminated.  All statements and agreements
contained in any certificate or other instrument delivered to USB under any
Loan Document shall be deemed representations and warranties by Borrower to
USB and/or agreements and covenants of Borrower under this Agreement.  The
representations, warranties, and covenants made by the Obligated Persons in
the Loan Documents, and the rights, powers, and privileges granted to USB in
the Loan Documents, are cumulative, and no Loan Document shall be construed in
the context of another to diminish, nullify or otherwise reduce the benefit to
USB of any such representation, warranty, covenant, right, power or privilege.
In particular and without limitation, no exception set out in this Agreement
to any representation, warranty or covenant herein contained shall apply to
any similar representation, warranty or covenant contained in any other Loan
Document, and each such similar representation, warranty or covenant shall be
subject only to those exceptions which are expressly made applicable to it by
the terms of the various Loan Documents.

     Section 8.3     Notices.  All notices, requests, consents, demands and
other communications required or permitted under any Loan Document shall be in
writing and, unless otherwise specifically provided in such Loan Document,
shall be deemed sufficiently given or furnished if delivered by personal
delivery, by expedited delivery service with proof of delivery, or by



                                      28

<PAGE>
registered or certified United States mail, return receipt requested, postage
prepaid, at the addresses specified below (unless changed by similar notice in
writing given by the particular Person whose address is to be changed).  Any
such notice or communication shall be deemed to have been given upon receipt:

Borrower's address:      950 Seventeenth Street, Suite 800
                         Denver, Colorado 80202
                         Attention: Stanton E. Ross

USB's address:           918 Seventeenth Street, DN-CO-BB3E
                         Denver, Colorado  80202
                         Attention: Mark E. Thompson

     Section 8.4     Parties in Interest.  All grants, covenants and
agreements contained in the Loan Documents shall bind and inure to the benefit
of the parties thereto and their respective successors and assigns; provided,
however, that no Obligated Person may assign or transfer any of its rights or
delegate any of its duties or obligations under any Loan Document without the
prior consent of USB.

     Section 8.5     USB's Damage Limitation.  USB shall not be liable to any
Obligated Person for consequential damages, whatever the nature of a breach by
USB in its obligations relating to the transactions governed or contemplated
by this Agreement.

     Section 8.6     Governing Law.  The Loan Documents shall be deemed
contracts and instruments made under the laws of the State of Colorado and
shall be construed and enforced in accordance with and governed by the laws
(excluding the conflicts of law rules) of the State of Colorado and the laws
of the United States of America, except: (a) to the extent that the law of
another jurisdiction is expressly elected in a Loan Document, and (b) with
respect to specific Liens, or the perfection thereof, evidenced by Security
Documents covering real or personal property which by the laws applicable
thereto are required to be construed under the laws of another jurisdiction.
Borrower hereby irrevocably submits itself to the non-exclusive jurisdiction
of the state and federal courts of the State of Colorado.

     Section 8.7     Limitation on Interest.  USB and Borrower intend to
contract in strict compliance with applicable usury law from time to time in
effect.  In furtherance thereof such persons stipulate and agree that none of
the terms and provisions contained in the Loan Documents shall ever be
construed to create a contract to pay, for the use, forbearance or detention
of money, interest in excess of the maximum amount of interest permitted to be
charged by applicable law from time to time in effect.  Neither any Obligated
Person nor any present or future guarantors, endorsers, or other Persons
hereafter becoming liable for payment of any Obligation shall ever be liable
for unearned interest thereon or shall ever be required to pay interest
thereon in excess of the maximum amount that may be lawfully charged under
applicable law from time to time in effect, and the provisions of this section
shall control over all other provisions of the Loan Documents which may be in
conflict or apparent conflict herewith.  USB expressly disavows any intention
to charge or collect excessive unearned interest or finance charges in the
event the maturity of any Obligation is accelerated.  If: (a) the maturity of
any Obligation is accelerated for any reason, (b) any Obligation is prepaid
and as a result any amounts held to constitute interest are determined to be
in excess of the legal maximum, or (c) USB or any other holder of any or all
of the Obligations shall otherwise collect moneys which are determined to



                                      29

<PAGE>
constitute interest which would otherwise increase the interest on any or all
of the Obligations to an amount in excess of that permitted to be charged by
applicable law then in effect, then all such sums determined to constitute
interest in excess of such legal limit shall, without penalty, be promptly
applied to reduce the then outstanding principal of the related Obligations
or, at USB's option, promptly returned to Borrower or the other payor thereof
upon such determination.

     Section 8.8     Severability.  If any term or provision of any Loan
Document shall be determined to be illegal or unenforceable all other terms
and provisions of the Loan Documents shall nevertheless remain effective and
shall be enforced to the fullest extent permitted by applicable law.

     Section 8.9     Counterparts.  This Agreement may be separately executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to constitute one
and the same Agreement.

     Section 8.10     Conflicts.  To the extent of any irreconcilable
conflicts between the provisions of this Agreement and the provisions of any
of the Loan Documents, the provisions of this Agreement shall prevail.

     Section 8.11     Entire Agreement.  This Agreement, the Note, the
Security Documents and the other Loan Documents from time to time executed in
connection herewith state the entire agreement between the parties with
respect to the subject matter hereof.

     Section 8.12     Arbitration.  Subject to the provisions of the next
paragraph below, USB and Borrower agree to submit to binding arbitration any
and all claims, disputes and controversies between USB and Borrower (and their
respective employees, officers, directors, attorneys and other agents)
relating to the Loan, the Loan Documents and the negotiation, execution,
collateralization, administration, repayment, modification, extension or
collection of the foregoing.  Such arbitration shall proceed in Denver,
Colorado, shall be governed by Colorado law (including without limitation the
provisions of CRS 13-21-102(5)) and shall be conducted in accordance with the
Commercial Arbitration Rules of the American Arbitration Association (the
"AAA").  Any award entered in an arbitration, whether on motions or at a
hearing, with or without testimony from witnesses, shall be made by a written
opinion stating the reasons for the award made.  The decision of any
arbitration pursuant to this Agreement shall be made based on Colorado law
without reference to any choice of law rules.  Judgment on any award hereunder
may be entered in any court having jurisdiction.

     Nothing in the preceding paragraph, nor the exercise of any right to
arbitrate thereunder, shall limit the right of any party hereto: (a) to
foreclose against any real or personal property collateral by the exercise of
the power of sale under a deed of trust, mortgage, or other security agreement
or instrument or applicable law; (b) to exercise self-help remedies such as
setoff or repossession; or (c) to obtain provisional or ancillary remedies
such as replevin, injunctive relief, attachment or appointment of a receiver
from a court having jurisdiction, before, during or after the pendency of any
arbitration proceeding.  The institution and maintenance of any action for
such judicial relief, or pursuit of provisional or ancillary remedies, or
exercise of self-help remedies shall not constitute a waiver of the right or
obligation of any party to submit any claim or dispute to arbitration,
including those claims or disputes arising from exercise of any judicial
relief, or pursuit of provisional or ancillary remedies or exercise of
self-help remedies.


                                      30

     Arbitration hereunder shall be before a three-person panel of neutral

an appellate court level: (2) a person with at least 10 years experience in

                                PROMISSORY NOTE

$25,000,000                                      September 4, 2003
                                                 Denver, Colorado

     FOR VALUE RECEIVED, INFINITY OIL & GAS OF WYOMING, INC., a Wyoming
corporation ("Borrower"), promises to pay to the order of U.S. BANK NATIONAL
ASSOCIATION ("Payee"), the principal sum of $25,000,000 (or so much thereof as
may be borrowed hereunder), together with interest on the outstanding unpaid
balance of such principal amount at the rates provided below.

     This Note is issued pursuant to, and is subject to the terms and
provisions of, the Credit Agreement dated as of September 4, 2003, between
Borrower and Payee, as now in effect or as the same may hereafter be amended,
restated, extended, renewed or otherwise modified (the "Credit Agreement").
Except as otherwise defined herein, terms defined in the Credit Agreement
shall have the same meanings when used herein.

     The outstanding principal amount of this Note shall be due and payable as
provided in the Credit Agreement.  Any then-unpaid principal balance of this
Note shall be due and payable on the Maturity Date (unless due and payable
sooner pursuant to the terms of the Credit Agreement) and shall bear interest
at the rates provided in the Credit Agreement.

     Interest shall accrue daily on the unpaid principal balance of this Note,
shall be due and payable on the last day of each calendar month and at the
maturity of this Note, and shall be calculated on the basis of a 360-day year,
and the actual number of days elapsed.

     All payments of principal and interest hereon shall be made at Payee's
offices at 918 Seventeenth Street, Denver, Colorado 80202, or at such other
place as Payee shall have designated to Borrower in writing, in immediately
available funds and without set-off or counterclaim or deduction of any kind.
All payments received hereunder shall be applied first to costs of collection,
second to accrued interest as of the date of payment and third to the
outstanding principal balance of this Note.

     Notwithstanding anything to the contrary contained in this Note, from and
after the expiration of any applicable period of grace provided for in the
Credit Agreement, overdue principal, and (to the extent permitted under
applicable law) overdue interest, whether caused by acceleration of maturity
or otherwise, shall bear interest at a fluctuating rate, adjustable the day of
any change in such rate, equal to three and one-half percentage points above
the Prime Rate, until paid, and shall be due and payable on demand.

     This Note is secured by, and the holder of this Note is entitled to the
benefits of, the documents described in the Credit Agreement (the "Security
Documents").  Reference is made to the Security Documents for a description of
the property covered thereby and the rights, remedies and obligations of the
holder hereof in respect thereto.

     Subject to the expiration of any applicable period of grace provided for
in the Credit Agreement, in the event of: (a) any default in any payment of
the principal of or interest on this Note when due and payable, or (b) any
other Event of Default (as defined in the Credit Agreement), then the whole
principal sum of this Note plus accrued interest and all other obligations of
Borrower to Payee, direct or indirect, absolute or contingent, now existing or
hereafter arising, shall, at the option of Payee, become immediately due and


                                      A-1

<PAGE>
payable, and any or all of the rights and remedies provided herein and in the
Credit Agreement and the Security Documents, as they may be amended, modified
or supplemented from time to time may be exercised by Payee.

     If Borrower fails to pay any amount due under this Note and Payee has to
take any action to collect the amount due or to exercise its rights under the
Security Documents, including without limitation retaining attorneys for
collection of this Note, or if any suit or proceeding is brought for the
recovery of all or any part of or for protection of the indebtedness or to
foreclose the Security Documents or to enforce Payee's rights under the
Security Documents, then Borrower agrees to pay on demand all reasonable costs
and expenses of any such action to collect, suit or proceeding, or any appeal
of any such suit or proceeding, incurred by Payee, including without
limitation the reasonable fees and disbursements of Payee's attorneys and
their staff.

     Borrower waives presentment, notice of dishonor and protest, and assents
to any extension of time with respect to any payment due under this Note, to
any substitution or release of collateral and to the addition or release of
any party, except as provided in the Credit Agreement.  No waiver of any
payment or other right under this Note shall operate as a waiver of any other
payment or right.

     If any provision in this Note shall be held invalid, illegal or
unenforceable in any jurisdiction, the validity, legality or enforceability of
any defective provisions shall not be in any way affected or impaired in any
other jurisdiction.

     No delay or failure of the holder of this Note in the exercise of any
right or remedy provided for hereunder shall be deemed a waiver of such right
by the holder hereof, and no exercise of any right or remedy shall be deemed a
waiver of any other right or remedy that the holder may have.

     All notices given hereunder shall be given as provided in the Credit
Agreement.

     At the option of the holder hereof, an action may be brought to enforce
this Note in the District Court in and for the City and County of Denver,
State of Colorado, in the United States District Court for the District of
Colorado or in any other court in which venue and jurisdiction are proper.
Borrower and all signers or endorsers hereof consent to venue and jurisdiction
in the District Court in and for the City and County of Denver, State of
Colorado and in the United States District Court for the District of Colorado
and to service of process under Sections 13-1-124(1)(a) and 13-1-125, Colorado
Revised Statutes (2001), as amended, in any action commenced to enforce this
Note.

     This Note is to be governed by and construed according to the laws of the
State of Colorado.
