                              INTERESTS OF PARTIES

A.      Interest of Parties in Costs and Production:

        All production of oil and gas from the Contract Area shall be owned in
accordance with each party's respective interest as set forth in Annex "I" (4)
of this Agreement. Unless otherwise provided in this agreement, all costs and
liabilities incurred in operations hereunder shall be borne and paid, and all
equipment and material acquired in operations on the Contract Area shall be
owned by the parties as their interest appears in Annex "I" (4). With respect to
any lease hereby covered, each party entitled to receive a share of production
of oil and gas from the Contract Area shall bear and cause to be paid or
delivered, to the extent of its interest in such production, any and all

<PAGE>

royalty, overriding royalty, production payment or other burden of each lease
made subject hereto and all production resulting therefrom.

        Nothing contained in this Article III (A) shall be deemed an assignment
or cross-assignment of interests covered hereby.

B.      Oil and Gas Interests:

        If any interest listed in Annex "I" (4) is an unleased oil and gas
interest, such oil and gas interest shall be treated for the purposes of this
Agreement as if it were a leased interest under the form of oil and gas lease or
leases subject to this Agreement and such interest shall be allocated one-eighth
to royalty and seven-eights to leasehold interests.

C.      Excess Royalties, Overriding Royalties and Other Payments:

        Unless changed by other provisions, if the interest of any party covered
hereby is subject to any royalty, overriding royalty, production payment or
other burden on production in excess of the amount stipulated in Annex "I" (4),
such party so burdened shall assume and alone bear all such excess obligations
and shall indemnify and hold the other parties hereto harmless from any and all
claims and demands for payment asserted by owners of such excess burden.

D.      Subsequently Created Interests:

        If any party should hereafter create an overriding royalty, production
payment or other burden payable out of production attributable to its working
interest hereunder, and:

        1. If the burdened party is required to reassign or relinquish under
this agreement to any other party or parties all or a portion of its working
interest hereunder and/or the production attributable thereto, said other party
or parties shall receive said assignment and/or production free and clear of
said subsequently created interest and the burdened party shall indemnify and
save said other party or parties harmless from any claims and demands for
payment asserted by owners of the subsequently created interest; and,

        2. If the burdened party fails to pay, when due, its share of expenses
chargeable hereunder, all provisions of this agreement governing the repayment
of such expenses, including the right to withhold proceeds or to cause the
purchaser to withhold proceeds, shall be enforceable against the subsequently
created interest in the same manner as they are enforceable against the working
interest of the burdened party.

                                   ARTICLE IV.

                                     TITLES

A.      Title Examination:

         Title Examination shall be made either on the drillsite of a subject
well or upon the lease(s) to be included in the drilling unit around such well
on a complete abstract record furnished to an outside attorney employed by
Operator for this purpose, and the title to any such lease or leases and the fee
title of the lessors therein must be approved by the examining attorney and
accepted by the Operator prior to the commencement of drilling operations on any
well drilled hereunder; however, in the event any well drilled hereunder is
completed as a commercial producer and the lease on which the well is located is
pooled or unitized with other leases to form either a declared unit or a spacing
unit designated by a governmental authority, Operator shall examine the title to
the lease(s) and land included in said unit on an abstract certified to a date
subsequent to the date on which such well was completed. A good faith effort
shall be made by the Operator to satisfy the examining attorney's title
requirements covering the drillsite tract, or any lease or leases covered hereby

<PAGE>

and included in a declared unit or spacing unit designated by a governmental
authority. All title information necessary for the examination of title shall be
obtained by the Operator. All costs incurred by Operator in procuring abstracts
and fees paid attorneys including original, supplemental and division order
title opinions, and the cost of satisfying any title requirements or curing any
title defects, insofar as such costs relate to leases or land covered by this
operating agreement, including the filing of a lawsuit if deemed necessary by
operator's attorney to cure a title defect or to obtain a lease, shall be
charged to the joint account and borne by the Non-Operators in the proportion
that each Non-Operator is responsible f or the payment of all costs. Operator
shall be responsible for the preparation and recording of pooling designations
or declarations as well as the conduct of hearings before governmental agencies
for the securing of spacing or pooling orders.

B.      Failure of Title:

         If after all titles are accepted and approved, any oil and gas interest
or lease, or interest therein, be lost through failure of title, which loss
results in a reduction of interest from that shown on Annex "I", such loss or
losses shall be regarded as joint losses and shall be borne by the Operator and
Non-Operators in proportion to their respective interests in the Contract Area.
There shall be no monetary liability against the Operator, its employees or
agents resulting from such loss nor shall there be any change or adjustment in
the interests of the parties in the remaining portion of the Contract Area.

C.      Loss of Leases For Other Than Title Failure:

         If any lease or interest subject to this agreement be lost through
failure to develop, failure to pay delay rental or shut-in gas payments, or
because express or implied covenants have not been performed, or if any lease be
permitted to expire at the end of its primary term and not be renewed or
extended, the loss shall not be considered a failure of title and all such
losses shall be joint losses and shall be borne by all parties in proportion to
their interest and there shall be no change in, or adjustment of, the interest
in the remaining portion of the Contract Premises. No monetary liability shall
result against Operator, its employees or agents, should loss of title occur due
to any of the foregoing or should minimum royalty or royalty not be paid or be
paid erroneously, through mistake or oversight. In the event such loss requires
a revision in the ownership of an oil and gas interest or lease in the Contract
Area, such revision shall be borne jointly by all Drilling Parties as their
respective interests appear in Annex "I".

                                   ARTICLE V.

                                    OPERATOR

A.      Designation and Responsibilities of Operator:

         Rife Oil Properties, Inc. or its designate shall be the Operator of the
Contract Area, and shall conduct and direct and have full control of all
operations on the Contract Area as permitted and required by and within the
limits of this agreement. It shall conduct all such operations in a good and
workmanlike manner, but it shall have no liability as Operator to the other
parties for losses sustained or liabilities incurred, except such as may result
from gross negligence or willful misconduct. Rife Oil Properties, Inc. is hereby
named Operator of the Contact Area even should it not be vested with title or
later become divested of title to the Contract Area. For the purposes of this
Agreement, title held by an affiliate of the Operator or by a party that
controls or is controlled by the Operator shall be deemed an interest owned by
Operator and each Non-Operator by execution of this Agreement hereby agree,
consent and acknowledge same.

B.      Resignation or Removal of Operator and Selection of Successor:
<PAGE>


         Operator may resign at any time by giving written notice of not less
than sixty (60) days to Non-Operators. In such event, all parties to this
agreement, including Operator if it owns an interest in the Contract Area, shall
by written ballot select by a majority vote in interest, not in numbers, a new
Operator who shall assume the responsibilities and duties on the date hereafter
provided, and shall have the rights prescribed for Operator by this agreement.
Operator shall deliver to its successor all records and information necessary to
the discharge by the new Operator of its duties and obligations within five (5)
business days after the receipt by Operator of a copy of the written ballots
indicating that its successor has been duly chosen and a written acceptance by
the successor of its responsibilities thereunder. Such acceptance shall contain
a provision holding Operator harmless from all liability resulting from any acts
performed in its capacity as Operator. Operator may be removed if it fails or
refuses to carry out its duties hereunder, or becomes insolvent, bankrupt or is
placed in receivership, by the affirmative vote of two (2) or more Non-Operators
owning a majority interest based on ownership as shown on Annex "I" remaining
after excluding the voting interest of Operator. Such resignation or removal
shall become effective at 7:00 a.m. on the first day of the calendar month
following the receipt by Operator of the written acceptance by its successor. In
the event Operator should voluntarily resign while it continues to maintain an
interest in the Contract Area, it shall be bound by the terms hereof as a
Non-Operator.

                                   ARTICLE VI.

                            DRILLING AND DEVELOPMENT

A.      Initial Well:

         All wells drilled on the Contract Area shall be drilled or caused to be
drilled by Operator at rates customary and usual in the area by contracts with
independent contractors who are doing work of a similar nature in the same
geographical area.

         Within a reasonable time after the execution hereof, Operator shall
commence the drilling of a well or wells for oil and gas on the Contract Area
identified in Annex "I" in accordance with the terms and conditions of this
agreement or any ancillary agreements between the parties executed prior to or
contemporaneously herewith. In the event of conflict, the terms and provisions
of any such ancillary agreement dated prior to or contemporaneously with this
agreement shall control. Operator shall make reasonable tests of all formations
encountered during drilling which give indication of containing oil and gas in
quantities sufficient to test, unless this agreement shall be limited to a
specific formation or formations, in which event Operator shall be required to
test only the formation or formations to which this agreement may apply.

B.      Subsequent Operations:

         The Operator is authorized on behalf of all Non-Operators to rework,
deepen, plug back or to otherwise engage in subsequent operations with respect
to a well drilled on the Contract Area owned by the Drilling Parties at the
joint expense of all parties and, except to the extent modified hereafter, shall
be undertaken without the prior knowledge or consent of the Non-Operators. The
entire cost and risk of conducting such subsequent operations shall be borne by
the Drilling Parties in proportion to their ownership in the Contract Area and
shall include all necessary expenditures for the reworking, plugging or
deepening, testing, completing, recompleting and equipping of the well,
including necessary tankage and/or surface facilities.

         An itemized statement of the cost of drilling, deepening, plugging
back, testing, completing, recompleting and equipping the well as set forth
above shall be furnished by the Operator to the Non-Operators and will be
included in the monthly billing within one hundred and twenty (120) days after

<PAGE>

the completion of any operation hereunder and as more fully set forth in the
Accounting Procedure attached hereto as Annex "II".

C.      Operations by Less Than All Parties:

         Notwithstanding the foregoing, Operator shall not undertake any single
project reasonably estimated to require an expenditure in excess of fifteen
thousand dollars ($15,000.00) in the aggregate without the express written
consent of the Drilling Parties as their respective interest appear in Annex
"I".

         In the event Operator or other Drilling Party shall elect to drill
another well on the Contract Area or to rework, deepen or plug back a dry hole
or a well not producing in paying quantities reasonably estimated to require an
expenditure in excess of fifteen thousand dollars ($15,000.00) in the aggregate
and not otherwise agreed to by the Drilling Parties by separate agreement, shall
give the other parties written notice of the proposed operation, specifying the
work to be performed, the location, proposed depth, objective formation and the
estimated cost of the operation. The parties so notified shall have thirty (30)
days after the receipt of the notice within which to notify the party wishing to
do the work whether they elect to participate in the cost of the proposed
operation. Failure of a party to reply within the period above fixed shall
constitute an election by that party not to participate in the cost of the
proposed operation. Any telephonic notice shall be confirmed in writing within
seven (7) days.

         Operator shall perform all work for the account of the Consenting
Parties; provided, however, if the Operator (or an affiliate of Operator vested
with title in the Contract Area) is a Non-Consenting Party, the Consenting
Parties shall either: (a) request Operator to perform the work for the
Consenting Parties, or (b) designate one of the Consenting Parties as Operator
for the limited purpose of performing such work. Such operations on the Contract
Area shall be in compliance with all the terms and conditions of this agreement.

         If less than all parties approve any proposed operation, the proposing
party, immediately after the expiration of the notice period, shall advise the
Consenting Parties of the total interest of the parties approving such operation
and its recommendations as to whether the Consenting Parties should proceed with
the operation as proposed. Each Consenting Party shall advise the proposing
party of its desire to limit participation to such party's interest as shown on
Annex "I" (4) or to carry its proportionate share of Non- Consenting Parties
interests, and failure to advise shall be deemed an election to limit
participation. The proposing party, at its election, may withdraw such proposal
if there is insufficient participation and shall promptly notify all parties of
such decision. (See Annex "IV" for forfeiture provisions if operations are
necessary to continue lease in force or to drill well.)

         The entire cost and risk of conducting such operations shall be borne
by the Consenting Parties in the proportions they have elected to bear same
under the terms of the preceding paragraph. Consenting Parties shall keep the
leasehold estates involved in such operations free and clear of all liens and
encumbrances of every kind created by or arising from the operations of the
Consenting Parties and shall hold Non-Consenting Parties harmless from all
liabilities resulting therefrom. If such an operation results in a dry hole, the
Consenting Parties shall plug and abandon the well and restore the surface
location at. their sole cost, risk and expense. If any well drilled, reworked,
deepened or plugged back under the provisions of this article VI (C) result in a
producer of oil and/or gas in paying quantities, the Consenting Parties shall
complete and equip the well at their sole cost and risk and the well shall then
be turned over to Operator and shall be operated by it at the expense and for
the account of the Consenting Parties in accordance with this agreement,
including Article VI (G) dealing with the abandonment of productive wells.

         Upon commencement of operations of the subject well, each
Non-Consenting Party shall be deemed to have relinquished to Consenting Parties,
and the Consenting Parties shall own and be entitled to receive, in proportion
to their interests, all of such Non-Consenting Party's Interest in the well and
<PAGE>

share of production therefrom. Each Non-Consenting Party shall then assign to
the Consenting Party, in accordance with their respective interests therein and
without warranty of any kind, as to title, or as to quantity, quality or fitness
for use of the equipment and material, all of their interest in the well and its
equipment, free of mortgage or lien, together with their interest in the
leasehold estate as to the drilling unit of the well. There shall be no
readjustment of interest in the remaining portion of the Contract Area. After
the assignment, the Non-Consenting Parties shall have no further responsibility,
liability or interest in the operation of or production from the well or the
assigned area surrounding said well. All operations conducted under such
Drillsite shall remain subject to the terms and provisions of this agreement.

D.      Taking Production In Kind:

         Each party shall take in kind or separately dispose of its
proportionate share of all oil and gas produced from the Contract Area. Any
extra expenditure incurred in the taking in kind or separate disposition by any
party of its proportionate share of the production shall be borne by such party.
Any party taking its share of production in kind shall be required to pay for
only its proportionate share of such part of Operator's surface facilities which
it uses. Each party shall execute division orders and contracts as may be
necessary for the sale of its interest in production from the Contract Area,
and, except as provided in Article VII hereof, shall be entitled to receive
payment directly from the purchaser thereof for its share of production.

         In the event any party shall fail to make the arrangements necessary to
take in kind or separately dispose of its proportionate share of the oil and gas
produced from the Contract Area, Operator shall have the right, subject to the
revocation at will by the party owning it, to act as such party's agent for the
purpose of selling it to others at any time and from time to time, for the
account of the non-taking party at the contract price agreed to by Operator and
the purchaser thereof. Any sale by Operator of any other party's share of oil or
gas shall be only for such reasonable periods of time consistent with industry
needs, but in no event for a period of more than one (1) year. Operator shall
under no circumstances make a sale into interstate commerce of any other party's
share of gas production without first giving such party thirty (30) days notice
of such intended sale.

E.      Access to Contract Area and Information:

         Each party shall have access to the Contract Area at all reasonable
times at it sole cost and risk to inspect or observe operations, and shall have
access at reasonable times to information pertaining to the development or
operation thereof, including Operator's books and records relating thereto.

F.      Surplus Material and Equipment:

         Materials and equipment acquired pursuant hereto, which in the judgment
of Operator are not necessary for the development and operation of the Contract
Area, may be sold by Operator for the joint account to any of the parties
hereto, to others, or to itself for operations unrelated to the Contract Area,
at a price determined in accordance with the Accounting Procedure, set forth in
Annex "II", attached hereto. Proper charges and credit shall be made by Operator
as provided in such Accounting Procedure.

G.      Abandonment of Dry Holes and Wells that have Produced.

         Except for any well in which a Non-Consent operation has been conducted
hereunder which may be plugged and abandoned in accordance with Article VI (C)
hereof, any well which has been drilled, reworked, deepened, or plugged back
pursuant to this agreement on the Contract Area and, in the sole discretion of
the Operator, is considered a dry hole or has been completed as a producer but
has become non-commercial, shall be plugged and abandoned by the Operator
without the prior knowledge and consent of the Drilling Parties. All such wells
<PAGE>

shall be plugged and abandoned in accordance with applicable rules and
regulations governing such activities and at the cost, risk and expense of the
parties who participated in the cost of drilling and/or deepening such well in
proportion to their ownership in the Contract Area.

         In the event a party not subject to this agreement wishes to take over
operations from the Drilling Parties of a well deemed by Operator to be a dry
hole or non-commercial, such party shall tender to the Operator on behalf of all
Drilling Parties the value of the well's salvageable material and equipment,
less the estimated cost of salvaging and the estimated cost of plugging and
abandoning as determined by the Operator, such funds to be treated as a credit
to the joint account of the Drilling Parties in accordance with the provisions
of Accounting Procedure attached hereto as Annex "II". At the request of
Operator, each Drilling Party shall then assign to such party, without warranty
of any kind, as to title, or as to quantity, quality or fitness for use of the
equipment and material, all of their interest in the well and its equipment,
free of mortgage or lien, together with their interest in the leasehold estate
as to the drilling unit of the subject well. These assignments shall have no
effect upon the interest in the remaining portion of the Contract Area. After
the assignment, the Drilling Party shall have no further responsibility,
liability or interest in the operation of or production from the well or the
assigned area surrounding said well and the assigned area shall cease to be
operated in accordance with the terms of this agreement.

                                  ARTICLE VII.

                      EXPENDITURES AND LIABILITY OF PARTIES

A.      Leasehold Expenditures:

         Operator shall have full control of the Contract Premises and, subject
to the provisions hereof, shall conduct and manage the development and operation
of said premises for the production of oil and gas. Operator shall pay and
discharge all costs and expenses incurred pursuant hereto, and shall charge each
of the parties hereto with their respective proportionate share thereof upon the
basis provided in the Accounting Procedure attached hereto as Annex "II" and
made a part hereof; provided, however, if any provision of said Annex "II"
conflicts with any provision hereof, the provisions hereof shall control.
Operator shall keep an accurate record of the joint account hereunder showing
expenses incurred and charges and credits made and received. Each non-operating
party shall pay to operator its share of such costs and expenditures within
fifteen (15) days after receipt of the Operator's monthly billing of same. If
payment is not made within such time, the unpaid balance shall bear interest at
the maximum rate permitted under Texas law until paid. Should Operator pay the
unpaid amount, it shall, to obtain reimbursement thereof, be subrogated to the
security rights described in the below paragraph.

         In the event of failure or neglect of any Non-Operator to promptly pay
its proportionate part of any costs or expenses of development or operation when
due, Operator shall have the right, without prejudice to other rights or
remedies, to withhold the proceeds from the sale of such Non-Operator's share of
oil and/or gas or to direct the purchaser of the oil and/or gas produced in the
Contract Area to deliver such proceeds to the Operator until the amount owed
Operator by such Non-Operator, plus interest, has been paid. Each purchaser
shall be entitled to rely upon Operator's written statement concerning the
amount of default. Alternatively, should production proceeds be insufficient to
repay Operator for the proportionate part of any costs or expenses of
development or operation incurred by a delinquent Non-Operator, Operator may
require the other parties hereto to proportionately contribute to the payment of
such delinquent indebtedness and the parties so contributing shall be entitled
to share, in proportion to their contribution, the lien rights of Operator as
hereafter provided, to secure the payment of any sums so required to be paid to
them. Upon the payment by such delinquent or defaulting party to Operator of any
amount on such delinquent indebtedness, or upon any recovery on behalf of the
parties hereto under the withholding provisions described above or pursuant to
the lien conferred hereinbelow, the amount so paid or recovered shall be
<PAGE>

distributed and paid by Operator to the other parties hereto in accordance with
the contributions made by them.

         Except as herein otherwise specifically stated, the Operator, at its
election, shall have the right from time to time to demand and receive from the
other parties payment in advance of their respective shares of the estimated
amount of the expense to be incurred in operations hereunder during the next
succeeding month, which right may be exercised only by submission to each such
party of an itemized statement of such estimated expense, together with an
invoice for its share thereof. Each such statement and invoice for the payment
in advance of estimated expense shall be submitted on or before the 15th day
after receipt of the billing or by the first day of the month for which the
advance is required, whichever is later. Each party shall pay to Operator its
proportionate share of such estimate within fifteen (15) days after such
estimate and invoice is received. If any party fails to pay its share of said
estimate within said time, the amount due shall bear interest at the maximum
rate provided under Texas law until paid. Proper adjustment shall be made
monthly between advances and actual expense to the end that each party shall
bear and pay its proportionate share of actual expenses incurred, and no more.

B.      Liens and Payment Defaults:

         Each Non-Operator grants to Operator a first and preferred lien upon
its oil and gas rights in the Contract Area, and a security interest in its
share of oil and/or gas when extracted and its interest in all equipment
situated on the leasehold, to secure payment of its share of expense, together
with interest thereon at the maximum rate provided under Texas law. To the
extent Operator has a security interest under the Uniform Commercial Code or
comparable statute in the state where the Contract Area is situated, Operator
shall be entitled to exercise the rights and remedies of a secured party under
the Code. The bringing of a suit and the obtaining of judgment by Operator for
the secured indebtedness shall not be deemed an election of remedies or
otherwise affect the lien rights or security interest as security for the
payment thereof. If Operator should elect to proceed to foreclose the lien of
Operator as against the interest of a Non-Operator having an interest in the
Contract Area, this Operating Agreement shall be deemed to include provisions
for non-judicial sale under the laws of any state so permitting and M. 0. Rife,
III is hereby appointed Trustee for such purpose. The filing for record of this
Operating Agreement, or a memorandum making reference to such Operating
Agreement, duly signed and acknowledged by the defaulting Non-Operator or its
attorney-in-fact in the county where the Contract Area is situated, shall
constitute an Operator's Lien Statement.

         On such default, said Trustee or Operator shall at least 21 days
preceding the date of non-judicial sale serve written notice of the proposed
sale by certified mail on Non-Operator according to the records of Operator.
Service of such notice shall be deemed completed upon deposit of a notice
enclosed in a post-paid letter properly addressed to the Non-Operator and each
other party obligated to pay said obligations at the most recent address or
addresses as shown on the records of Operator in a post office or other official
depository under the care and custody of the United States or other official
depository under the care and custody of the United States Postal Service. The
affidavit of any person having knowledge of the fact of mailing and that such
mailing was completed shall be prima facie evidence of due delivery to
Non-Operator. After such notice, said Trustee shall proceed to sell all or part
of the interests of Non-Operator in the Contract Area at public auction to the
highest bidder for cash after having given notice of the time and place of sale
and in the manner and after the advertisement of such sale as is now required by
the statutes of the state where the Contract Area is situated in making sales of
real estate under powers of sale provided in deeds of trust. Sale of a part of
the realty will not exhaust the power of sale and sales may be made from time to
time until all of the property is sold or the obligations paid in full. Said
Trustee shall have authority to appoint an attorney-in-fact to act as Successor
Trustee in conducting the foreclosure sale and executing a deed to the
purchaser; and it is further agreed that said Trustee or his successor may sell
said property together or in lots, parcels, and/or proration units as he shall
deem expedient and after such sales as aforesaid shall make, execute and deliver
to the purchaser or purchasers thereof good and sufficient deeds, assignments or
other lawful conveyances to vest in said purchaser of purchasers title of the
<PAGE>

Non-Operator in the Contract Area in fee simple together with all of the
proceeds of production attributable thereto including proceeds of production
held by any party for the payment to Non-Operator. From the proceeds of said
sale and Trustee shall first pay all charges, costs and expenses in executing
these provisions and secondly pay any sums due by the Trustee for taxes in the
preservation of the security and thereafter pay all of the remaining sums to
Operator for the satisfaction of the debts of Non-Operator hereunder and the
balance, if any, shall be paid by the purchaser of the interest to the
defaulting Non-Operator. It is agreed that such sale shall be a perpetual bar
against Non-Operator and its heirs, successors and assigns and legal
representatives and all other persons claiming under him, them or any of them.
It is further agreed that said Trustee or any holder or holders of said
obligation of Operator shall have the right to become the purchaser or
purchasers at such sale if the highest bidder or bidders in which event the bid
or bids may be credited upon said indebtedness of Non-Operator. It is stipulated
and agreed that in case of any sale hereunder by Trustee or his successor, all
prerequisites of said sale shall be presumed to have been performed, and any
conveyance given hereunder including all statements of fact or recitals therein
made as to the nonpayment of money secured, or as to any default under the terms
hereof, or as to the request of the Trustee to enforce this trust, or as to the
advertisement of sale or the time, place and terms of sale, or as to any other
preliminary act or thing, shall be taken in all courts of law and equity as
prima facie evidence that the facts so stated are true. Operator may appoint a
substitute or successor Trustee in the event the Trustee above named is unable
or unwilling for any reason to serve.

C.      Liability of Parties:

         The liability of the parties shall be several, not joint or collective.
Each party shall be responsible only for its obligations, and shall be liable
only for its proportionate share of the costs of developing and operating the
Contract Area. Accordingly, the liens granted among the parties in the preceding
paragraph are given to secure only the debts of each severally. It is not the
intention of the parties to create, nor shall this agreement be construed as
creating, a mining or other partnership or association, or to render the parties
liable as partners.

D.      Rentals, Shut-in Well Payments and Minimum Royalties:

         Rentals, shut-in payments and minimum royalties which may be required
under the terms of any lease shall be paid by the Drilling Parties in proportion
to their ownership in the applicable lease. The Operator shall make any and all
payments for and on behalf of all such parties. In the event of failure to make
proper payment of any rental, shut-in well payment or minimum royalty through
mistake or oversight where such payment is required to continue the lease in
force, any loss which results from such non-payment shall be borne jointly by
all Drilling Parties as their respective interest appear in Annex "I". If any
party secures a new lease covering the terminated interest, such acquisition
shall be subject to the extension and renewal provisions of this agreement.

E.      Taxes:

         Beginning with the first calendar year after the effective date hereof,
Operator shall render for ad-valorem taxation all property subject to this
agreement which by law should be rendered for such taxes, and it shall pay all
such taxes assessed thereon before they become delinquent. Operator shall bill
the other parties for their proportionate shares of all tax payments in the
manner provided in Annex "II".

         If Operator considers any tax assessment improper, Operator may, at its
discretion, protest within the time and manner prescribed by law, and prosecute
the protest to a final determination, unless it elects to abandon such protest
prior to final determination. All legal costs incurred in connection with any
administrative or judicial proceeding relating to tax assessments shall be
considered a joint expense of all parties to this Agreement.
<PAGE>


         Operator shall pay or cause to be paid on behalf of all Drilling
Parties all production, severance, excise, gathering and other taxes imposed
upon or with respect to the production or handling of oil and/or gas produced
under the terms of this agreement.

         Each of the parties hereto elects, under the authority of Section 761
(a) of the Internal Revenue Code of 1954, as amended, and under the authority of
the income tax laws of any state which contain provisions similar to those
contained in the Subchapter of the Internal Revenue Code of 1954, to be excluded
from the application of all of the provisions of Subchapter K of Chapter 1 of
Subtitle A of the Internal Revenue Code of 1954. Each party authorizes and
directs Operator to execute such an election or elections on its behalf and to
file the election with the proper governmental office or agency. If requested by
Operator, each party agrees to execute and join in such election.

F.      Insurance:

         At all times while operations are conducted hereunder, Operator shall
comply with the workmen's compensation law of the state where the operations are
being conducted. Operator shall also carry or provide insurance for the benefit
of the joint account of the parties as outlined in Annex "III" attached to and
made a part hereof. Operator shall require all contractors engaged in work on or
for the Contract Area to comply with the workmen's compensation law of the state
where the operations are being conducted and to maintain such other insurance as
Operator may require.

         No direct charge shall be made by Operator for premiums paid for
Automobile Public Liability Insurance for automobiles owned solely by Operator.

                                  ARTICLE VIII.

                ACQUISITION, MAINTENANCE OR TRANSFER OF INTEREST

A.      Assignment of Leases:

         Leases will initially be acquired by the Operator. Record title to each
such Lease shall continue to be held in the name of the Operator until a
Producing Well is obtained, at which time the title to the Contract Area will be
assigned and conveyed to the Drilling Parties as their respective interests
appear in Annex "I", subject to the terms of this Operating Agreement and all
third party contracts which are muniments of title in Operator's chain of title.
The respective interest to be assigned to each Non-Operator shall be such
party's undivided interest in the Contract Area as identified in Annex "I".

B.      Surrender of Leases:

         The leases covered by this agreement, insofar as they embrace acreage
in the Contract Area, may be released or surrendered, in whole or in part, by
the Operator on behalf of the Drilling Parties, and Operator shall give written
notice to each Non-Operator within ten (10) business days from the day such
lease(s), or portions thereof, are released or surrendered. Such notice by the
Operator to the other Drilling Parties shall recite that, in its opinion, such
leases have become worthless or that he is under a contractual obligation to
release the subject acreage. Accordingly, each Non-Operator hereby appoints
Operator as its attorney-in-fact to execute an instrument in writing to
surrender or release any lease(s) covered by this agreement without the joinder
of Non-Operators, provided it acts in good faith on behalf of Non-Operators. Any
contractual obligation to reassign the lease(s) covered by the Contract Area may
be executed or later ratified by all Non-Operators at the request of the
Operator.

         Any assignment, surrender or release of a lease, or portions thereof,
<PAGE>

covered by this agreement, shall not change the surrendering party's interest in
the balance of the Contract Area; and the acreage assigned, released or
otherwise surrendered, and subsequent operations thereon, shall not thereafter
be subject to the terms and provisions of this agreement.

C.       Renewal or Extension of Leases:

         If the Operator or other party subject hereto secures a renewal of any
oil and gas lease subject to this agreement, it shall be for the joint account
of all the Drilling Parties, insofar as such lease affects lands within the
Contract Area, subject to the right of Operator or other party to secure a lien
and security interest on the oil and gas rights and production resulting
therefrom of each Non-Operator in the Contract Area pending the reimbursement by
each Non-Operator of their proportionate share of the lease acquisition costs
allocated to that part of such lease within the Contract Area which shall be in
proportion to the interests held at that time by the parties in the Contract
Area. Each Non-Operator who participates in the purchase of a renewal lease in
accordance with this agreement shall be given an assignment of its proportionate
interest therein by the acquiring party.

         The provisions of this Article shall apply to the renewal or extension
of leases whether they are for the entire interest covered by the expiring lease
or cover only a portion of its area or an interest therein. Any renewal or
extension lease taken before the expiration of its predecessor lease, or taken
or contracted for within six (6) months after the expiration of the existing
lease shall be subject to this provision; but any lease taken or contracted for
more than six (6) months after the expiration of an existing lease shall not be
deemed a renewal lease and shall not be subject t the provisions of this
Agreement. However, a renewal or extension secured within one (1) year from the
expiration of the existing lease shall be subject to this provision if the delay
in securing such renewal or extension was done by Operator with the intent of
avoiding his obligations under this Article.

D.       Maintenance of Uniform Interest:

         For the purpose of maintaining uniformity of ownership in the oil and
gas leasehold interests covered by this agreement, no party shall sell,
encumber, transfer or make other disposition of its interest in the leases
embraced within the Contract Area and in wells, equipment and production unless
such disposition covers either:

         1. The entire interest of the party in all leases and equipment and
            production; or

         2. An EQUAL undivided interest in all leases and equipment and
            production in the Contract Area.

         Every such sale, encumbrance, transfer or other disposition made by any
party shall be made expressly subject to this agreement and shall be made
without prejudice to the right of the other parties.

E.       Waiver of Rights to Partition:

         If permitted by the laws of the state or states in which the property
covered hereby is located, each party hereto owning an undivided interest in the
Contract Area waives any and all rights it may have to partition and have set
aside to it in severalty its undivided interest therein.

F.       No Preferential Right to Purchase:

         Any party to this agreement may sell, transfer, mortgage or donate its
interest in the Contract Area to any other party without giving prior notice to
any other party hereunder, it being understood that there shall be no
preferential right to purchase under this agreement.
<PAGE>


                                   ARTICLE IX.

                               CLAIMS AND LAWSUITS

         Operator hereunder is entitled on behalf of all Non-Operators to
institute a lawsuit on an alleged cause of action arising out of operations on
the Contract Area, or on an alleged cause of action involving title to any lease
or oil and gas interest subject to this agreement on behalf of the joint account
of all parties hereunder with the prior consent of a majority in interest in the
Contract Area.

         If a third party damage claim, a claim involving title to any interest
subject to this agreement, or other suit is made on account of any matter
arising from operations hereunder against any party to this agreement, the claim
or suit shall be treated as a claim or suit involving the joint account. If any
Non-Operator is sued on account of any matter arising from operations hereunder
over which such party has no control because of the rights given Operator by
this agreement, such party shall immediately notify Operator, and the claim or
suit shall be treated as any other claim or suit involving the joint account.

         The prosecution or defense of lawsuits affecting the Contract Area
shall be under the exclusive control of the Operator for the joint account, who
shall be responsible for employing an attorney to represent all interest owners
in the Contract Area. Damage claims, title claims affecting all interest owners
in the Contract Area, or other suits arising out of operations on the Contract
Area may be settled or otherwise compromised during litigation by the Operator
on behalf of all parties, and all attorney fees and other expenses incurred in
the prosecution or defense of suits, together with the amount paid to discharge
any final judgement, shall be considered costs of operations and shall be
charged to and paid by all parties in proportion to their then interests in the
Contract Area; provided, however, that no lawsuit shall be settled or otherwise
compromised by the Operator for an amount in excess of Five Thousand Dollars
($5,000.00) without the prior approval of a majority in interest of the parties
then owning an interest in the Contract Area.

         The provisions of this paragraph shall not apply in any instance where
the loss which may result from the suit is treated as an individual loss rather
than a joint loss under prior provisions of this agreement or by law, and all
such suits shall be handled by and be the sole responsibility of the party or
parties concerned.

                                   ARTICLE X.

                                  FORCE MAJEURE

         If any party hereto is rendered unable, in whole or in part, by force
majeure to carry out its obligations under this agreement, other than to make
money payments due hereunder, it is agreed that the obligations of such party
insofar as they are affected by such force majeure shall be suspended during the
continuance of such inability but for no longer than, the continuance of the
force majeure. The affected party shall use all reasonable diligence to remove
the force majeure situation as quickly as possible; however, such situations
shall be handled within the complete discretion of the affected party.

         As used herein, the term "force majeure" shall mean an Acts of God,
strikes, riots, epidemics, landslides, lightning, fires, washouts, floods,
earthquakes, severe storms, arrests and restraints of rules and peoples,
governmental action, inaction, delay or restraint, unavailability or difficulty
in obtaining necessary materials or equipment, and any other cause, whether of
the kind specifically enumerated above or otherwise, which is foreseeable or not
reasonably within the control of the party claiming suspension.
<PAGE>

                                   ARTICLE XI.

                                     NOTICES

         All notices authorized or required between the parties and required by
any of the provisions of this agreement, unless otherwise specifically provided,
shall be given in writing by mail or telegram, postage or charges prepaid, and
addressed to the parties to whom the notice is given at the addresses listed on
Annex "I". The notice given under any provision hereof shall be deemed given and
received when deposited in the mail or with the telegraph company, with postage
or charges prepaid. Each party shall have the right to change its address at any
time, and from time to time, by giving written notice thereof to all other
parties.

                                  ARTICLE XII.

                               TERMS OF AGREEMENT

         This agreement shall remain in full force and effect as to the oil and
gas leases and/or oil and gas interests subject hereto for the period of time
below; provided, however, no party hereto shall ever be construed as having any
right, title or interest in or to any lease or oil and gas interest contributed
by any other party beyond the term of this agreement.

         a) So long as any of the oil and gas leases subject to this agreement
remain or are continued unreleased and in full force and effect as to any part
of the Contract Area, whether by production, extension, renewal or otherwise, or
until the well or wells situated on the Contract Area have been plugged and
abandoned, whichever event occurs last.

         b) In the event any part of the Contract Area is assigned to a third
party by a majority in interest including the Operator, this agreement shall be
terminated only insofar as it affects the assigned acreage, but shall remain
effective with respect to the balance of the Contract Area.

         It is agreed, however, that the termination of this agreement shall not
relieve any party hereto from any liability which has accrued or attached prior
to the date of such termination, and the provisions hereof relating to the
charging and payment of costs, the disposition of materials and equipment, and
distribution of proceeds shall remain in force until a final accounting is made.

                                  ARTICLE XIII.

                      COMPLIANCE WITH LAWS AND REGULATIONS

A.     Laws, Regulations and Orders:

         This agreement shall be subject to the conservation laws of the state
in which the Contract Area is located, to the valid rules, regulations, and
orders of any duly constituted regulatory body of said state; and to all other
applicable federal, state, and local laws, ordinances, rules, regulations, and
orders.

B.     Governing Law:

         This agreement and all matters pertaining hereto, including, but not
limited to, matters of performance, non-performance, breach, remedies,
procedures, rights, duties and interpretation or construction, shall be governed
and determined by the law of the State of Texas, and exclusive venue shall be
Tarrant County, Texas. All matters pertaining to title to the leasehold estate
<PAGE>

of the Contract Area or other matters which are considered "in rem" actions at
law, shall be governed and determined by the law of the state in which the
Contract Area is located. If the Contract Area is in two or more states, the law
of the state of Texas shall control.

C.     Regulatory Agencies:

         With respect to operations hereunder, Non-Operators agree to release
Operator from any and all losses, damages, injuries, claims and causes of action
arising out of, incident to or resulting directly or indirectly from Operator's
interpretation or application of rules, rulings, regulations or orders of the
Department of Energy or predecessor or successor agencies to the extent such
interpretation or application was made in good faith. In the event the Federal
Energy Regulatory Commission of any other governmental body having jurisdiction,
or any court having jurisdiction, shall require Operator to make any refund on
monies received from the sale of production from the Contract Area, each party
hereto agrees to bear and pay his proportionate part of any such refund,
including his proportionate part of any interest or penalty which must be paid.
Payment of all sums which become due and owing pursuant hereto shall be secured
by the lien and other rights of Operator described above. Non-Operators
authorize Operator to prepare and submit such documents as may be required to be
submitted to the purchaser of any crude oil or natural gas sold hereunder, to
any state or federal regulatory agency or to any other person or entity pursuant
to the requirements of any valid regulations or rules which may be issued by a
state or regulatory agency from time to time. Each party hereto agrees to
furnish any and all certifications or other information which is required to be
furnished in a timely manner and in sufficient detail to permit compliance.

                                  ARTICLE XIV.

                               GENERAL PROVISIONS

A.     Binding Provisions:

         The covenants and agreements contained herein shall be binding upon and
inure to the benefit of the heirs, legal representatives, successors and assigns
of the respective parties hereto.

B.     Counterparts:

         To facilitate execution, this Operating Agreement may be executed in as
many counterparts as may be convenient or required. It shall not be necessary
that the signature and acknowledgment of, or on behalf of each party, or that
the signature and acknowledgment of all persons required to bind any party,
appear on each counterpart. All counterparts shall collectively constitute a
single instrument. It shall not be necessary in making proof of this Operating
Agreement to produce or account for more than a single counterpart containing
the respective signatures and acknowledgment of, or on behalf of, each of the
parties hereto. Any signature and acknowledgment page to any counterpart may be
detached from such counterpart without impairing the legal effect of the
signatures and acknowledgments thereon and thereafter attached to another
counterpart identical thereto except having attached to it additional signatures
and acknowledgment pages.

C.     Severability of Provisions:

         If for any reason any provision or provisions hereof are determined to
be invalid or unenforceable and contrary to any existing or future law, such
invalidity or unenforceability shall not impair the operation of or affect those
portions of the agreement, which are valid.

D.     Not Entire Agreement:
<PAGE>
         This agreement may not constitute the entire agreement among the
parties. This agreement is subject to any letter, joint venture, farm-out or
other prior or contemporaneous agreement or understanding among the parties, but
after its execution, may not be modified or amended in any manner other than as
set forth herein.

E.     Amendments:

         Unless otherwise provided herein, this agreement may be modified or
amended upon the written consent of 75% of the Drilling Parties in interest.
However, any amendment to reflect the admission of a successor Operator must be
in compliance with Section V (B) of this agreement, and such amendment must be
signed by the Operator and the successor operator.

F.     Section Titles:

         Section titles are for descriptive purposes only and shall not control
or alter the meaning of the agreement as set forth in the text.

G.     General:

         1. To the extent deemed necessary by the Operator to pay operating
expenses and make other disbursements to third parties on behalf of
Non-Operators, commingling of funds is expressly permitted pursuant to this
agreement.

         2. Nothing herein contained shall in any way be construed in a manner
that would result in the creation of a fiduciary relationship or relationship of
trust between the Operator and Non-Operators. Any party making representations
inconsistent with the terms hereof is acting in express violation of the
agreement. Operator has a duty to act in good faith consistent with the
standards of a reasonably prudent operator.

         3. Non-Operator agrees and understands that Operator is not selling or
leasing any goods or services under the provisions of this Operating Agreement
as contemplated by the Deceptive Trade Practices Act of the State of Texas and
it is intended that the activities of Operator are considered as an
accommodation to Non-Operator to facilitate the payment of expenses and the
collection of revenue on the Contract Area. Accordingly, by execution hereof,
the parties to this agreement expressly waive the rights and remedies to which
they are entitled under the Texas Deceptive Trade Practices-Consumer Protection
Act in connection with operations conducted pursuant to this agreement.

                                   ARTICLE XV.

                                OTHER PROVISIONS

A. As to all gas production and at the election of Operator, each party agrees
to execute a division order in favor of Operator, entitling him to collect all
production revenues from the first purchaser and to remit all net proceeds
thereof to all Non-Operators.

B. Operator is hereby authorized to enter into such oil transport agreements,
gas purchase contracts or any other such agreements that will provide for the
marketability of oil, gas and gas liquids from the Contract Area.

C. Operator may, at its election, withhold or to direct the purchaser thereof to
withhold from any proceeds due to a Non-Operator, any sums due to Operator from
such Non-Operator as more fully provided in this agreement.

D. Notwithstanding any of the terms and provisions hereof, if it is necessary
<PAGE>

for Operator to hire or employ outside legal counsel to represent Operator
before the Railroad Commission of the State of Texas, or before any other
administrative agency, in connection with the Contract Area, all costs and
expenses incurred in such representation will be a direct charge to the joint
account.

E. It is understood and agreed by the parties that Operator shall charge to the
joint account all costs and expenses incurred by Operator for following
services: costs of outside royalty disbursement; costs for integrating gas
contracts; costs and expenses by outside vendors incurred in the preparation of
all necessary FERC filings for gas production, if any; and, any charges made by
tax consultants incurred should Operator hire such tax consultants to review
and/or protest any ad-valorem taxes rendered on the interests subject to this
agreement.

F. Each Non-Operator, by execution hereof or by execution of any other document
in which this agreement is attached as an Exhibit or Annex, irrevocably
constitutes and appoints the Operator, Rife Oil Properties, Inc., as its true
and lawful Agent and Attorney-In-Fact, for the limited purpose of executing any
documents required, authorized or deemed advisable in connection with the
obligations imposed upon it as Operator herein.

G. Each party hereto agrees that any transfer such parties should make of any
interest such party owns in the lands and leases covered hereby shall expressly
recite and reflect that such transfer is subject to the terms of this Operating
Agreement, as may be amended, and agrees to indemnify Operator from any losses
which Operator may suffer if such party should fail to do so.

H. Any party hereunder selling a portion of his or its interest in the leases
covered hereby shall be solely responsible for securing all assignments ,
transfer orders and required recordings to the full satisfaction of the Operator
and/or the first purchaser, as the case may be, and by delivering to such party
or parties a copy of all documents duly executed and recorded where required,
including a written ratification where necessary. Any parties selling a portion
of his or its interest shall remain liable for all operating and other costs of
development incurred prior to the date of the transfer order to buyer. Further,
any parties selling a portion of his or its interest shall be secondarily liable
to the Operator and to other non-selling parties for buyer's performance of all
provisions of this agreement. Such transfer shall be consistent with the terms
of this agreement relating to the Maintenance of Uniform Interest. It is further
understood that this liability shall extend and continue for as long as the
selling party retains an interest in the lease or leases which are presently or
hereafter covered by this agreement.

I. Notwithstanding anything herein to the contrary, if any Non-Operator neglects
or fails to pay sums due and owing Operator hereunder for a period of 60 days
after receipt of invoice therefore, Operator may notify Non-Operator of its
election to regard such Non-Operating Party as a Non-Consenting Party hereunder
as to said costs, whereupon Operator shall be liable therefore. If Non-Operator
fails to pay such amount within 10 days after receipt of such notice, then
Operator's election shall be effective, Non-Operator shall no longer owe said
sum to Operator and shall be subject to the non-consent provisions hereof the
same as if such party had elected to be a Non-Consenting Party at the inception
of the operation with Operator having all the rights of a Consenting Party, but
only with respect to the sums remaining unpaid by such Non-Operator. Provided,
however, this provision shall not be applicable to any sums owed Operator but
which Non-Operator contests in good faith.

J. ASSIGNMENT. It is understood that Non-Operator or its assigns may assign a
part of the acreage which results in different ownerships in separate tracts out
of the acres covered by this operating agreement; provided however, such
assignments must be subject to the terms of this operating agreement by the
acceptance of such assignment by the assignee, their heirs, successors and
assigns and ratify and agree that this operating agreement is to be interpreted
and construed as a separate and independent agreement by and between operator
and the owners of such separate tract, the same as if a new and separate
operating agreement was executed covering only the separate tract out of the
<PAGE>

contract area by and between operator and the owners of such separate tract.

K. Operator may elect to execute on its own behalf and pursuant to its power of
attorney hereby granted, a recording supplement in the office of the County
Clerk where the land covered by this agreement is located to the end that there
shall be constructive notice of the provisions of this Operating Agreement
placed upon said public records.

         IN WITNESS WHEREOF, this agreement is executed this the day of 2001, in
multiple counterparts, the original of which shall be maintained at the office
of the Operator.
