A.A.P.L. FORM 610 — MODEL FORM OPERATING AGREEMENT- 1989
If any provision of any exhibit, except Exhibits “E”, “F”, and “G”, is
inconsistent with any provision contained in the body of this agreement, the
provisions in the body of this agreement shall prevail.
ARTICLE III.
INTERESTS OF PARTIES
A. Oil and Gas Interests:
     If any party owns an Oil and Gas Interest in the Contract Area, that
Interest shall be treated for all purposes of this agreement and during the term
hereof as if it were covered by the form of Oil and Gas Lease attached hereto as
Exhibit “B”, and the owner thereof shall be deemed to own both royalty interest
in such lease and the interest of the lessee thereunder.
B. Interests of Parties in Costs and Production:
     Unless changed by other provisions, all costs and liabilities incurred in
operations under this agreement shall be borne and paid, and all equipment and
materials acquired in operations on the Contract Area shall be owned, by the
parties as their interests are set forth in Exhibit “A”. In the same manner, the
parties shall also own all production of Oil and Gas from the Contract Area
subject, however, to the payment of royalties and other burdens on production as
described hereafter.
     Regardless of which party has contributed any Oil and Gas Lease or Oil and
Gas Interest on which royalty or other burdens may be payable and except as
otherwise expressly provided in this agreement, each party shall pay or deliver,
or cause to be paid or delivered, all burdens on its share of the production
from the Contract Area up to, but not in excess of, ___and shall indemnify,
defend and hold the other parties free from any liability therefor. Except as
otherwise expressly provided in this agreement, if any party has contributed
hereto any Lease or Interest which is burdened with any royalty, overriding
royalty, production payment or other burden on production in excess of the
amounts stipulated above, such party so burdened shall assume and alone bear all
such excess obligations and shall indemnify, defend and hold the other parties
hereto harmless from any and all claims attributable to such excess burden.
However, so long as the Drilling Unit for the productive Zone(s) is identical
with the Contract Area, each party shall pay or deliver, or cause to be paid or
delivered, all burdens on production from the Contract Area due under the terms
of the Oil and Gas Lease(s) which such party has contributed to this agreement,
and shall indemnify, defend and hold the other parties free from any liability
therefor.
     No party shall ever be responsible, on a price basis higher than the price
received by such party, to any other party’s lessor or royalty owner, and if
such other party’s lessor or royalty owner should demand and receive settlement
on a higher price basis, the party contributing the affected Lease shall bear
the additional royalty burden attributable to such higher price.
     Nothing contained in this Article III.B. shall be deemed an assignment or
cross-assignment of interests covered hereby, and in the event two or more
parties contribute to this agreement jointly owned Leases, the parties’
undivided interests in said Leaseholds shall be deemed separate leasehold
interests for the purposes of this agreement.
C. Subsequently Created Interests:
     If any party has contributed hereto a Lease or Interest that is burdened
with an assignment of production given as security for the payment of money, or
if, after the date of this agreement, any party creates an overriding royalty,
production payment, net profits interest, assignment of production or other
burden payable out of production attributable to its working interest hereunder,
such burden shall be deemed a “Subsequently Created Interest.” Further, if any
party has contributed hereto a Lease or Interest burdened with an overriding
royalty, production payment, net profits interest, or other burden payable out
of production created prior to the date of this agreement, and such burden is
not shown on Exhibit “A”, such burden also shall be deemed a Subsequently
Created Interest to the extent such burden causes the burdens on such party’s
Lease or Interest to exceed the amount stipulated in Article III.B. above.
     The party whose interest is burdened with the Subsequently Created Interest
(the “Burdened Party”) shall assume and alone bear, pay and discharge the
Subsequently Created Interest and shall indemnify, defend and hold harmless the
other Parties from and against any liability therefor. Further, if the Burdened
Party fails to pay, when due, its share of expenses chargeable hereunder, all
provisions of Article VII.B. shall be enforceable against the Subsequently
Created Interest in the same manner as they are enforceable against the working
interest of the Burdened Party. If the Burdened Party is required under this
agreement to assign or relinquish to any other party, or parties, all or a
portion of its working interest 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, defend and hold harmless said other party, or parties, from any and
all claims and demands for payment asserted by owners of the Subsequently
Created Interest.
ARTICLE IV.
TITLES
A. Title Examination:
     Title examination shall be made on the Drillsite of any proposed well prior
to commencement of drilling operations and, if a majority in interest of the
Drilling Parties so request or Operator so elects, title examination shall be
made on the entire Drilling Unit, or maximum anticipated Drilling Unit, of the
well. The opinion will include the ownership of the working interest, minerals,
royalty, overriding royalty and production payments under the applicable Leases.
Each party contributing Leases and/or Oil and Gas Interests to be included in
the Drillsite or Drilling Unit, if appropriate, shall furnish to Operator all
abstracts (including federal lease status reports), title opinions, title papers
and curative material in its possession free of charge. All such information not
in the possession of or made available to Operator by the parties, but necessary
for the examination of the title, shall be obtained by Operator. Operator shall
cause title to be examined by attorneys on its staff or by outside attorneys.
Copies of all title opinions shall be furnished to each Drilling Party. Costs
incurred by Operator in procuring abstracts, fees paid outside attorneys for
title examination (including preliminary, supplemental, shut-in royalty opinions
and division order title opinions) and other direct charges as provided in
Exhibit “C” shall be borne by the Drilling Parties in the proportion that the
interest of each Drilling Party bears to the total interest of all Drilling
Parties as such interests appear in Exhibit “A”. Operator shall make no charge
for services rendered by its staff attorneys or other personnel in the
performance of the above functions.
     Each party shall be responsible for securing curative matter and pooling
amendments or agreements required in connection with Leases or Oil and Gas
Interests contributed by such party. Operator shall be responsible for the
preparation and recording of pooling designations or declarations and
communitization agreements as well as the conduct of hearings before
governmental agencies for the securing of spacing or pooling orders or any other
orders necessary or appropriate to the conduct of operations hereunder. This
shall not prevent any party from appearing on its own behalf at such hearings.
Costs incurred by Operator, including fees paid to outside attorneys, which are
associated with hearings before governmental agencies, and which costs are
necessary and proper for the activities contemplated under this agreement, shall
be direct charges to the joint account and shall not be covered by the
administrative overhead charges as provided in Exhibit “C.”

 

--------------------------------------------------------------------------------

 

A.A.P.L. FORM 610 — MODEL FORM OPERATING AGREEMENT- 1989
Operator shall make no charge for services rendered by its staff attorneys or
other personnel in the performance of the above functions.
     No well shall be drilled on the Contract Area until after (1) the title to
the Drillsite or Drilling Unit, if appropriate, has been examined as above
provided, and (2) the title has been approved by the examining attorney or title
has been accepted by all of the Drilling Parties in such well.
B. Loss or Failure of Title:
     1. Failure of Title: Should any Oil and Gas Interest or Oil and Gas Lease
be lost through failure of title, which results in a reduction of interest from
that shown on Exhibit “A,” the party credited with contributing the affected
Lease or Interest (including, if applicable, a successor in interest to such
party) shall have ninety (90) days from final determination of title failure to
acquire a new lease or other instrument curing the entirety of the title
failure, which acquisition will not be subject to Article VIII.B., and failing
to do so, this agreement, nevertheless, shall continue in force as to all
remaining Oil and Gas Leases and Interests; and,
          (a) The party credited with contributing the Oil and Gas Lease or
Interest affected by the title failure (including, if applicable, a successor in
interest to such party) shall bear alone the entire loss and it shall not be
entitled to recover from Operator or the other parties any development or
operating costs which it may have previously paid or incurred, but there shall
be no additional liability on its part to the other parties hereto by reason of
such title failure;
          (b) There shall be no retroactive adjustment of expenses incurred or
revenues received from the operation of the Lease or Interest which has failed,
but the interests of the parties contained on Exhibit “A” shall be revised on an
acreage basis, as of the time it is determined finally that title failure has
occurred, so that the interest of the party whose Lease or Interest is affected
by the title failure will thereafter be reduced in the Contract Area by the
amount of the Lease or Interest failed;
          (c) If the proportionate interest of the other parties hereto in any
producing well previously drilled on the Contract Area is increased by reason of
the title failure, the party who bore the costs incurred in connection with such
well attributable to the Lease or Interest which has failed shall receive the
proceeds attributable to the increase in such interest (less costs and burdens
attributable thereto) until it has been reimbursed for unrecovered costs paid by
it in connection with such well attributable to such failed Lease or Interest;
          (d) Should any person not a party to this agreement, who is determined
to be the owner of any Lease or Interest which has failed, pay in any manner any
part of the cost of operation, development, or equipment, such amount shall be
paid to the party or parties who bore the costs which are so refunded;
          (e) Any liability to account to a person not a party to this agreement
for prior production of Oil and Gas which arises by reason of title failure
shall be borne severally by each party (including a predecessor to a current
party) who received production for which such accounting is required based on
the amount of such production received, and each such party shall severally
indemnify, defend and hold harmless all other parties hereto for any such
liability to account;
          (f) No charge shall be made to the joint account for legal expenses,
fees or salaries in connection with the defense of the Lease or Interest claimed
to have failed, but if the party contributing such Lease or Interest hereto
elects to defend its title it shall bear all expenses in connection therewith;
and
          (g) If any party is given credit on Exhibit “A” to a Lease or Interest
which is limited solely to ownership of an interest in the wellbore of any well
or wells and the production therefrom, such party’s absence of interest in the
remainder of the Contract Area shall be considered a Failure of Title as to such
remaining Contract Area unless that absence of interest is reflected on Exhibit
“A”.
     2. Loss by Non-Payment or Erroneous Payment of Amount Due: If, through
mistake or oversight, any rental, shut-in well payment, minimum royalty or
royalty payment, or other payment necessary to maintain all or a portion of an
Oil and Gas Lease or Interest is not paid or is erroneously paid, and as a
result a Lease or Interest terminates, there shall be no monetary liability
against the party who failed to make such payment. Unless the party who failed
to make the required payment secures a new Lease or Interest covering the same
interest within ninety (90) days from the discovery of the failure to make
proper payment, which acquisition will not be subject to Article VIII.B., the
interests of the parties reflected on Exhibit “A” shall be revised on an acreage
basis, effective as of the date of termination of the Lease or Interest
involved, and the party who failed to make proper payment will no longer be
credited with an interest in the Contract Area on account of ownership of the
Lease or Interest which has terminated. If the party who failed to make the
required payment shall not have been fully reimbursed, at the time of the loss,
from the proceeds of the sale of Oil and Gas attributable to the lost Lease or
Interest, calculated on an acreage basis, for the development and operating
costs previously paid on account of such Lease or Interest, it shall be
reimbursed for unrecovered actual costs previously paid by it (but not for its
share of the cost of any dry hole previously drilled or wells previously
abandoned) from so much of the following as is necessary to effect
reimbursement:
          (a) Proceeds of Oil and Gas produced prior to termination of the Lease
or Interest, less operating expenses and lease burdens chargeable hereunder to
the person who failed to make payment, previously accrued to the credit of the
lost Lease or Interest, on an acreage basis, up to the amount of unrecovered
costs;
          (b) Proceeds of Oil and Gas, less operating expenses and lease burdens
chargeable hereunder to the person who failed to make payment, up to the amount
of unrecovered costs attributable to that portion of Oil and Gas thereafter
produced and marketed (excluding production from any wells thereafter drilled)
which, in the absence of such Lease or Interest termination, would be
attributable to the lost Lease or Interest on an acreage basis and which as a
result of such Lease or Interest termination is credited to other parties, the
proceeds of said portion of the Oil and Gas to be contributed by the other
parties in proportion to their respective interests reflected on Exhibit “A”;
and,
          (c) Any monies, up to the amount of unrecovered costs, that may be
paid by any party who is, or becomes, the owner of the Lease or Interest lost,
for the privilege of participating in the Contract Area or becoming a party to
this agreement.
     3. Other Losses: All losses of Leases or Interests committed to this
agreement other than those set forth in Articles IV.B.1. and IV.B.2. above shall
be joint losses and shall be borne by all parties in proportion to their
interests shown on Exhibit “A”. This shall include but not be limited to the
loss of any Lease or Interest through failure to develop or because express or
implied covenants have not been performed (other than performance which requires
only the payment of money), and the loss of any Lease by expiration at the end
of its primary term if it is not renewed or extended. There shall be no
readjustment of interests in the remaining portion of the Contract Area on
account of any joint loss.
     4. Curing Title: In the event of a Failure of Title under Article IV.B.1.
or a loss of title under Article IV.B.2. above, any Lease or Interest acquired
by any party hereto (other than the party whose interest has failed or was lost)
during the ninety (90) day period provided by Article IV.B. I. and
Article IV.B.2. above covering all or a portion of the interest that has failed
or was lost shall be offered at cost to the party whose interest has failed or
was lost, and the provisions of Article VIII.B shall not apply to such
acquisition.

A.A.P.L. FORM 610 — MODEL FORM OPERATING AGREEMENT- 1989
ARTICLE V.
OPERATOR
A. Designation and Responsibilities of Operator:
EnerVest Operating, L.L.C. 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. In its
performance of services hereunder for the Non-Operators, Operator shall be an
independent contractor not subject to the control or direction of the
Non-Operators except as to the type of operation to be undertaken in accordance
with the election procedures contained in this agreement. Operator shall not be
deemed, or hold itself out as, the agent of the Non-Operators with authority to
bind them to any obligation or liability assumed or incurred by Operator as to
any third party. Operator shall conduct its activities under this agreement as a
reasonable prudent operator, in a good and workmanlike manner, with due
diligence and dispatch, in accordance with good oilfield practice, and in
compliance with applicable law and regulation, but in no event shall it have any
liability as Operator to the other parties for losses sustained or liabilities
incurred except such as may result from gross negligence or willful misconduct.
B. Resignation or Removal of Operator and Selection of Successor:
     1. Resignation or Removal of Operator: Operator may resign at any time by
giving written notice thereof to Non-Operators. If Operator terminates its legal
existence, no longer owns an interest hereunder in the Contract Area , or is no
longer capable of serving as Operator, Operator shall be deemed to have resigned
without any action by Non-Operators, except the selection of a successor.
Operator may be removed only for good cause by the affirmative vote of
Non-Operators owning a majority interest based on ownership as shown on Exhibit
“A” remaining after excluding the voting interest of Operator; such vote shall
not be deemed effective until a written notice has been delivered to the
Operator by a Non-Operator detailing the alleged default and Operator has failed
to cure the default within thirty (30) days from its receipt of the notice or,
if the default concerns an operation then being conducted, within forty-eight
(48) hours of its receipt of the notice. For purposes hereof, “good cause” shall
mean not only gross negligence or willful misconduct but also the material
breach of or inability to meet the standards of operation contained in
Article V.A. or material failure or inability to perform its obligations under
this agreement.
     Subject to Article VII.D.l., such resignation or removal shall not become
effective until 7:00 o’clock A.M. on the first day of the calendar month
following the expiration of ninety (90) days after the giving of notice of
resignation by Operator or action by the Non-Operators to remove Operator,
unless a successor Operator has been selected and assumes the duties of Operator
at an earlier date. Operator, after effective date of resignation or removal,
shall be bound by the terms hereof as a Non-Operator. A change of a corporate
name or structure of Operator or transfer of Operator’s interest to any single
subsidiary, parent or successor corporation shall not be the basis for removal
of Operator.
     2. Selection of Successor Operator: Upon the resignation or removal of
Operator under any provision of this agreement, a successor Operator shall be
selected by the parties. The successor Operator shall be selected from the
parties owning an interest in the Contract Area at the time such successor
Operator is selected. The successor Operator shall be selected by the
affirmative vote of two (2) or more parties owning a majority interest based on
ownership as shown on Exhibit “A” provided, however, if an Operator which has
been removed or is deemed to have resigned fails to vote or votes only to
succeed itself, the successor Operator shall be selected by the affirmative vote
of the party or parties owning a majority interest based on ownership as shown
on Exhibit “A” remaining after excluding the voting interest of the Operator
that was removed or resigned. The former Operator shall promptly deliver to the
successor Operator all records and data relating to the operations conducted by
the former Operator to the extent such records and data are not already in the
possession of the successor operator. Any cost of obtaining or copying the
former Operator’s records and data shall be charged to the joint account.
     3. Effect of Bankruptcy: If Operator becomes insolvent, bankrupt or is
placed in receivership, it shall be deemed to have resigned without any action
by Non-Operators, except the selection of a successor. If a petition for relief
under the federal bankruptcy laws is filed by or against Operator, and the
removal of Operator is prevented by the federal bankruptcy court, all
Non-Operators and Operator shall comprise an interim operating committee to
serve until Operator has elected to reject or assume this agreement pursuant to
the Bankruptcy Code, and an election to reject this agreement by Operator as a
debtor in possession, or by a trustee in bankruptcy, shall be deemed a
resignation as Operator without any action by Non-Operators, except the
selection of a successor. During the period of time the operating committee
controls operations, all actions shall require the approval of two (2) or more
parties owning a majority interest based on ownership as shown on Exhibit “A”.
In the event there are only two (2) parties to this agreement, during the period
of time the operating committee controls operations, a third party acceptable to
Operator, Non-Operator and the federal bankruptcy court shall be selected as a
member of the operating committee, and all actions shall require the approval of
two (2) members of the operating committee without regard for their interest in
the Contract Area based on Exhibit “A”.
C. Employees and Contractors:
     The number of employees or contractors used by Operator in conducting
operations hereunder, their selection, and the hours of labor and the
compensation for services performed shall be determined by Operator, and all
such employees or contractors shall be the employees or contractors of Operator.
D. Rights and Duties of Operator:
     1. Competitive Rates and Use of Affiliates: All wells drilled on the
Contract Area shall be drilled on a competitive contract basis at the usual
rates prevailing in the area. If it so desires, Operator may employ its own
tools and equipment in the drilling of wells, but its charges therefor shall not
exceed the prevailing rates in the area and the rate of such charges shall be
agreed upon by the parties in writing before drilling operations are commenced,
and such work shall be performed by Operator under the same terms and conditions
as are customary and usual in the area in contracts of independent contractors
who are doing work of a similar nature. All work performed or materials supplied
by affiliates or related parties of Operator shall be performed or supplied at
competitive rates, pursuant to written agreement, and in accordance with customs
and standards prevailing in the industry.
     2. Discharge of Joint Account Obligations: Except as herein otherwise
specifically provided, Operator shall promptly pay and discharge expenses
incurred in the development and operation of the Contract Area pursuant to this
agreement and shall charge each of the parties hereto with their respective
proportionate shares upon the expense basis provided in Exhibit “C”. Operator
shall keep an accurate record of the joint account hereunder, showing expenses
incurred and charges and credits made and received. Attached to and made a part
of Exhibit C hereto shall be Addenda indicating the direct charges and overhead
for specific regions within the **
     3. Protection from Liens: Operator shall pay, or cause to be paid, as and
when they become due and payable, all accounts of contractors and suppliers and
wages and salaries for services rendered or performed, and for materials
supplied on, to or in respect of the Contract Area or any operations for the
joint account thereof, and shall keep the Contract Area free from
**Contract Area.

A.A.P.L. FORM 610 — MODEL FORM OPERATING AGREEMENT- 1989
liens and encumbrances resulting therefrom except for those resulting from a
bona fide dispute as to services rendered or materials supplied.
     4. Custody of Funds: Operator shall hold for the account of the
Non-Operators any funds of the Non-Operators advanced or paid to the Operator,
either for the conduct of operations hereunder or as a result of the sale of
production from the Contract Area, and such funds shall remain the funds of the
Non-Operators on whose account they are advanced or paid until used for their
intended purpose or otherwise delivered to the Non-Operators or applied toward
the payment of debts as provided in Article VII.B. Nothing in this paragraph
shall be construed to establish a fiduciary relationship between Operator and
Non-Operators for any purpose other than to account for Non-Operator funds as
herein specifically provided. Nothing in this paragraph shall require the
maintenance by Operator of separate accounts for the funds of Non-Operators
unless the parties otherwise specifically agree.
     5. Access to Contract Area and Records: Operator shall, except as otherwise
provided herein, permit each Non-Operator or its duly authorized representative,
at the Non-Operator’s sole risk and cost, full and free access at all reasonable
times to all operations of every kind and character being conducted for the
joint account on the Contract Area and to the records of operations conducted
thereon or production therefrom, including Operator’s books and records relating
thereto. Such access rights shall not be exercised in a manner interfering with
Operator’s conduct of an operation hereunder and shall not obligate Operator to
furnish any geologic or geophysical data of an interpretive nature unless the
cost of preparation of such interpretive data was charged to the joint account.
Operator will furnish to each Non-Operator upon request copies of any and all
reports and information obtained by Operator in connection with production and
related items, including, without limitation, meter and chart reports,
production purchaser statements, run tickets and monthly gauge reports, but
excluding purchase contracts and pricing information to the extent not
applicable to the production of the Non-Operator seeking the information. Any
audit of Operator’s records relating to amounts expended and the appropriateness
of such expenditures shall be conducted in accordance with the audit protocol
specified in Exhibit “C”.
     6. Filing and Furnishing Governmental Reports: Operator will file, and upon
written request promptly furnish copies to each requesting Non-Operator not in
default of its payment obligations, all operational notices, reports or
applications required to be filed by local, State, Federal or Indian agencies or
authorities having jurisdiction over operations hereunder. Each Non-Operator
shall provide to Operator on a timely basis all information necessary to
Operator to make such filings.
     7. Drilling and Testing Operations: The following provisions shall apply to
each well drilled hereunder, including but not limited to the Initial Well:
          (a) Operator will promptly advise Non-Operators of the date on which
the well is spudded, or the date on which drilling operations are commenced.
          (b) Operator will send to Non-Operators such reports, test results and
notices regarding the progress of operations on the well as the Non-Operators
shall reasonably request, including, but not limited to, daily drilling reports,
completion reports, and well logs.
          (c) Operator shall adequately test all Zones encountered which may
reasonably be expected to be capable of producing Oil and Gas in paying
quantities as a result of examination of the electric log or any other logs or
cores or tests conducted hereunder.
     8. Cost Estimates. Upon request of any Consenting Party, Operator shall
furnish estimates of current and cumulative costs incurred for the joint account
at reasonable intervals during the conduct of any operation pursuant to this
agreement. Operator shall not be held liable for errors in such estimates so
long as the estimates are made in good faith.
     9. Insurance: At all times while operations are conducted hereunder,
Operator shall comply with the workers compensation law of the state where the
operations are being conducted; provided, however, that Operator may be a
self-insurer for liability under said compensation laws in which event the only
charge that shall be made to the joint account shall be as provided in Exhibit
“C”. Operator shall also carry or provide insurance for the benefit of the joint
account of the parties as outlined in Exhibit “D” attached hereto and made a
part hereof. Operator shall require all contractors engaged in work on or for
the Contract Area to comply with the workers compensation law of the state where
the operations are being conducted and to maintain such other insurance as
Operator may require.
     In the event automobile liability insurance is specified in said Exhibit
“D”, or subsequently receives the approval of the parties, no direct charge
shall be made by Operator for premiums paid for such insurance for Operator’s
automotive equipment.
ARTICLE VI.
DRILLING AND DEVELOPMENT
     1. Proposed Operations: If any party hereto should desire to drill any well
on the Contract Area or if any party should desire to Rework, Sidetrack, Deepen,
Recomplete or Plug Back a dry hole or a well no longer capable of producing in
paying quantities in which such party has not otherwise relinquished its
interest in the proposed objective Zone under this agreement, the party desiring
to drill, Rework, Sidetrack, Deepen, Recomplete or Plug Back such a well shall
give written notice of the proposed operation to the parties who have not
otherwise relinquished their interest in such objective Zone

 

--------------------------------------------------------------------------------

 

A.A.P.L. FORM 610 — MODEL FORM OPERATING AGREEMENT- 1989
under this agreement and to all other parties in the case of a proposal for
Sidetracking or Deepening, specifying the work to be performed, the location,
proposed depth, objective Zone and the estimated cost of the operation. The
parties to whom such a notice is delivered shall have thirty (30) days after
receipt of the notice within which to notify the party proposing to do the work
whether they elect to participate in the cost of the proposed operation. If a
drilling rig is on location, notice of a proposal to Rework, Sidetrack,
Recomplete, Plug Back or Deepen may be given by telephone and the response
period shall be limited to twenty-four (24) hours, Failure of a party to whom
such notice is delivered 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 proposal by a party to conduct an operation conflicting with the
operation initially proposed shall be delivered to all parties within the time
and in the manner provided in Article VI.B.6.
          If all parties to whom such notice is delivered elect to participate
in such a proposed operation, the parties shall be contractually committed to
participate therein provided such operations are commenced within the time
period hereafter set forth, and Operator shall, no later than ninety (90) days
after expiration of the notice period of thirty (30) days (or as promptly as
practicable after the expiration of the twenty-four (24) hour period when a
drilling rig is on location, as the case may be), actually commence the proposed
operation and thereafter complete it with due diligence at the risk and expense
of the parties participating therein; provided, however, said commencement date
may be extended upon written notice of same by Operator to the other parties,
for a period of up to thirty (30) additional days if, in the sole opinion of
Operator, such additional time is reasonably necessary to obtain permits from
governmental authorities, surface rights (including rights-of-way) or
appropriate drilling equipment, or to complete title examination or curative
matter required for title approval or acceptance. If the actual operation has
not been commenced within the time provided (including any extension thereof as
specifically permitted herein or in the force majeure provisions of Article XI)
and if any party hereto still desires to conduct said operation, written notice
proposing same must be resubmitted to the other parties in accordance herewith
as if no prior proposal had been made. Those parties that did not participate in
the drilling of a well for which a proposal to Deepen or Sidetrack is made
hereunder shall, if such parties desire to participate in the proposed Deepening
or Sidetracking operation, reimburse the Drilling Parties in accordance with
Article VI.B.4. in the event of a Deepening operation and in accordance with
Article VI.B.5. in the event of a Sidetracking operation.
     2. Operations by Less Than All Parties:
          (a) Determination of Participation. If any party to whom such notice
is delivered as provided in Article VI.B. 1. or VI.C.l. (Option No. 2) elects
not to participate in the proposed operation, then, in order to be entitled to
the benefits of this Article, the party or parties giving the notice and such
other parties as shall elect to participate in the operation shall, no later
than ninety (90) days after the expiration of the notice period of thirty
(30) days (or as promptly as practicable after the expiration of the twenty-four
(24) hour period when a drilling rig is on location, as the case may be)
actually commence the proposed operation and complete it with due diligence.
Operator shall perform all work for the account of the Consenting Parties;
provided, however, if no drilling rig or other equipment is on location, and if
Operator is a Non-Consenting Party, the Consenting Parties shall either:
(i) request Operator to perform the work required by such proposed operation for
the account of the Consenting Parties, or (ii) designate one of the Consenting
Parties as Operator to perform such work. The rights and duties granted to and
imposed upon the Operator under this agreement are granted to and imposed upon
the party designated as Operator for an operation in which the original Operator
is a Non-Consenting Party. Consenting Parties, when conducting operations on the
Contract Area pursuant to this Article VI.B.2., shall comply with all terms and
conditions of this agreement.
          If less than all parties approve any proposed operation, the proposing
party, immediately after the expiration of the applicable notice period, shall
advise all Parties of the total interest of the parties approving such operation
and its recommendation as to whether the Consenting Parties should proceed with
the operation as proposed. Each Consenting Party, within twenty-four (24) hours
after delivery of such notice, shall advise the proposing party of its desire to
(i) limit participation to such party’s interest as shown on Exhibit “A” or
(ii) carry only its proportionate part (determined by dividing such party’s
interest in the Contract Area by the interests of all Consenting Parties in the
Contract Area) of Non-Consenting Parties’ interests, or (iii) carry its
proportionate part (determined as provided in (ii)) of Non-Consenting Parties’
interests together with all or a portion of its proportionate part of any
Non-Consenting Parties’ interests that any Consenting Party did not elect to
take. Any interest of Non-Consenting Parties that is not carried by a Consenting
Party shall be deemed to be carried by the party proposing the operation if such
party does not withdraw its proposal. Failure to advise the proposing party
within the time required shall be deemed an election under (i). In the event a
drilling rig is on location, notice may be given by telephone, and the time
permitted for such a response shall not exceed a total of twenty-four
(24) hours. The proposing party, at its election, may withdraw such proposal if
there is less than 100% participation and shall notify all parties of such
decision within ten (10) days, or within twenty-four (24) hours if a drilling
rig is on location, following expiration of the applicable response period. If
100% subscription to the proposed operation is obtained, the proposing party
shall promptly notify the Consenting Parties of their proportionate interests in
the operation and the party serving as Operator shall commence such operation
within the period provided in Article VI.B.1., subject to the same extension
right as provided therein.
          (b) Relinquishment of Interest for Non-Participation . 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.
If such an operation results in a dry hole, then subject to Articles VI.B.6. and
VI.E.3., the Consenting Parties shall plug and abandon the well and restore the
surface location at their sole cost, risk and expense; provided, however, that
those Non-Consenting Parties that participated in the drilling, Deepening or
Sidetracking of the well shall remain liable for, and shall pay, their
proportionate shares of the cost of plugging and abandoning the well and
restoring the surface location insofar only as those costs were not increased by
the subsequent operations of the Consenting Parties. If any well drilled,
Reworked, Sidetracked, Deepened, Recompleted or Plugged Back under the
provisions of this Article results in a well capable of producing Oil and/or Gas
in paying quantities, the Consenting Parties shall Complete and equip the well
to produce at their sole cost and risk, and the well shall then be turned over
to Operator (if the Operator did not conduct the operation) and shall be
operated by it at the expense and for the account of the Consenting Parties.
Upon commencement of operations for the drilling, Reworking, Sidetracking,
Recompleting, Deepening or Plugging Back of any such well by Consenting Parties
in accordance with the provisions of this Article, 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 respective
interests, all of such Non-Consenting Party’s interest in the well and share of
production therefrom or, in the case of a Reworking, Sidetracking,

 

--------------------------------------------------------------------------------

 

A.A.P.L. FORM 610 — MODEL FORM OPERATING AGREEMENT- 1989
Deepening, Recompleting or Plugging Back, or a Completion pursuant to
Article VI.C.1. Option No. 2, all of such Non-Consenting Party’s interest in the
production obtained from the operation in which the Non-Consenting Party did not
elect to participate. Such relinquishment shall be effective until the proceeds
of the sale of such share, calculated at the well, or market value thereof if
such share is not sold (after deducting applicable ad valorem, production,
severance, and excise taxes, royalty, overriding royalty and other interests not
excepted by Article III.C. payable out of or measured by the production from
such well accruing with respect to such interest until it reverts), shall equal
the total of the following:
          (i) 400% of each such Non-Consenting Party’s share of the cost of any
newly acquired surface equipment beyond the wellhead connections (including but
not limited to stock tanks, separators, treaters, pumping equipment and piping),
plus 100% of each such Non-Consenting Party’s share of the cost of operation of
the well commencing with first production and continuing until each such
Non-Consenting Party’s relinquished interest shall revert to it under other
provisions of this Article, it being agreed that each Non-Consenting Party’s
share of such costs and equipment will be that interest which would have been
chargeable to such Non-Consenting Party had it participated in the well from the
beginning of the operations; and
          (ii) 400 % of (a) that portion of the costs and expenses of drilling,
Reworking, Sidetracking, Deepening, Plugging Back, testing, Completing, and
Recompleting, after deducting any cash contributions received under
Article VIII.C., and of (b) that portion of the cost of newly acquired equipment
in the well (to and including the wellhead connections), which would have been
chargeable to such Non-Consenting Party if it had participated therein.
     Notwithstanding anything to the contrary in this Article VI.B., if the well
does not reach the deepest objective Zone described in the notice proposing the
well for reasons other than the encountering of granite or practically
impenetrable substance or other condition in the hole rendering further
operations impracticable, Operator shall give notice thereof to each
Non-Consenting Party who submitted or voted for an alternative proposal under
Article VI.B.6. to drill the well to a shallower Zone than the deepest objective
Zone proposed in the notice under which the well was drilled, and each such
Non-Consenting Party shall have the option to participate in the initial
proposed Completion of the well by paying its share of the cost of drilling the
well to its actual depth, calculated in the manner provided in Article VI.B.4.
(a). If any such Non-Consenting Party does not elect to participate in the first
Completion proposed for such well, the relinquishment provisions of this
Article VI.B.2. (b) shall apply to such party’s interest.
     (c) Reworking, Recompletion or Plugging Back. An election not to
participate in the drilling, Sidetracking or Deepening of a well shall be deemed
an election not to participate in any Reworking or Plugging Back operation
proposed in such a well, or portion thereof, to which the initial non-consent
election applied that is conducted at any time prior to full recovery by the
Consenting Parties of the Non-Consenting Party’s recoupment amount. Similarly,
an election not to participate in the Completing or Recompleting of a well shall
be deemed an election not to participate in any Reworking operation proposed in
such a well, or portion thereof, to which the initial non-consent election
applied that is conducted at any time prior to full recovery by the Consenting
Parties of the Non-Consenting Party’s recoupment amount. Any such Reworking,
Recompleting or Plugging Back operation conducted during the recoupment period
shall be deemed part of the cost of operation of said well and there shall be
added to the sums to be recouped by the Consenting Parties 400 % of that portion
of the costs of the Reworking, Recompleting or Plugging Back operation which
would have been chargeable to such Non-Consenting Party had it participated
therein. If such a Reworking, Recompleting or Plugging Back operation is
proposed during such recoupment period, the provisions of this Article VI.B.
shall be applicable as between said Consenting Parties in said well.
     (d) Recoupment Matters. During the period of time Consenting Parties are
entitled to receive Non-Consenting Party’s share of production, or the proceeds
therefrom, Consenting Parties shall be responsible for the payment of all ad
valorem, production, severance, excise, gathering and other taxes, and all
royalty, overriding royalty and other burdens applicable to Non-Consenting
Party’s share of production not excepted by Article III.C.
     In the case of any Reworking, Sidetracking, Plugging Back, Recompleting or
Deepening operation, the Consenting Parties shall be permitted to use, free of
cost, all casing, tubing and other equipment in the well, but the ownership of
all such equipment shall remain unchanged; and upon abandonment of a well after
such Reworking, Sidetracking, Plugging Back, Recompleting or Deepening, the
Consenting Parties shall account for all such equipment to the owners thereof,
with each party receiving its proportionate part in kind or in value, less cost
of salvage.
     Within ninety (90) days after the completion of any operation under this
Article, the party conducting the operations for the Consenting Parties shall
furnish each Non-Consenting Party with an inventory of the equipment in and
connected to the well, and an itemized statement of the cost of drilling,
Sidetracking, Deepening, Plugging Back, testing, Completing, Recompleting, and
equipping the well for production; or, at its option, the operating party, in
lieu of an itemized statement of such costs of operation, may submit a detailed
statement of monthly billings. Each month thereafter, during the time the
Consenting Parties are being reimbursed as provided above, the party conducting
the operations for the Consenting Parties shall furnish the Non-Consenting
Parties with an itemized statement of all costs and liabilities incurred in the
operation of the well, together with a statement of the quantity of Oil and Gas
produced from it and the amount of proceeds realized from the sale of the well’s
working interest production during the preceding month. In determining the
quantity of Oil and Gas produced during any month, Consenting Parties shall use
industry accepted methods such as but not limited to metering or periodic well
tests. Any amount realized from the sale or other disposition of equipment newly
acquired in connection with any such operation which would have been owned by a
Non-Consenting Party had it participated therein shall be credited against the
total unreturned costs of the work done and of the equipment purchased in
determining when the interest of such Non-Consenting Party shall revert to it as
above provided; and if there is a credit balance, it shall be paid to such
Non-Consenting Party.
     If and when the Consenting Parties recover from a Non-Consenting Party’s
relinquished interest the amounts provided for above, the relinquished interests
of such Non-Consenting Party shall automatically revert to it as of 7:00 a.m. on
the day following the day on which such recoupment occurs, and, from and after
such reversion, such Non-Consenting Party shall own the same interest in such
well, the material and equipment in or pertaining thereto, and the production
therefrom as such Non-Consenting Party would have been entitled to had it
participated in the drilling, Sidetracking, Reworking, Deepening, Recompleting
or Plugging Back of said well. Thereafter, such Non-Consenting Party shall be
charged with and shall pay its proportionate part of the further costs of the
operation of said well in accordance with the terms of this agreement and
Exhibit “C” attached hereto.
     3. Stand-By Costs: When a well which has been drilled or Deepened has
reached its authorized depth and all tests have been completed and the results
thereof furnished to the parties, or when operations on the well have been
otherwise terminated pursuant to Article VI.F., stand-by costs incurred pending
response to a party’s notice proposing a Reworking,

 

--------------------------------------------------------------------------------

 

A.A.P.L. FORM 610 — MODEL FORM OPERATING AGREEMENT- 1989
Sidetracking, Deepening, Recompleting, Plugging Back or Completing operation in
such a well (including the period required under Article VI.B.6. to resolve
competing proposals) shall be charged and borne as part of the drilling or
Deepening operation just completed. Stand-by costs subsequent to all parties
responding, or expiration of the response time permitted, whichever first
occurs, and prior to agreement as to the participating interests of all
Consenting Parties pursuant to the terms of the second grammatical paragraph of
Article VI.B.2. (a), shall be charged to and borne as part of the proposed
operation, but if the proposal is subsequently withdrawn because of insufficient
participation, such stand-by costs shall be allocated between the Consenting
Parties in the proportion each Consenting Party’s interest as shown on Exhibit
“A” bears to the total interest as shown on Exhibit “A” of all Consenting
Parties.
          In the event that notice for a Sidetracking operation is given while
the drilling rig to be utilized is on location, any party may request and
receive up to five (5) additional days after expiration of the twenty-four (24)
hour response period specified in Article VI.B.1. within which to respond by
paying for all stand-by costs and other costs incurred during such extended
response period; Operator may require such party to pay the estimated stand-by
time in advance as a condition to extending the response period. If more than
one party elects to take such additional time to respond to the notice, standby
costs shall be allocated between the parties taking additional time to respond
on a day-to-day basis in the proportion each electing party’s interest as shown
on Exhibit “A” bears to the total interest as shown on Exhibit “A” of all the
electing parties.
     4. Deepening: If less than all the parties elect to participate in a
drilling, Sidetracking, or Deepening operation proposed pursuant to
Article VI.B.1., the interest relinquished by the Non-Consenting Parties to the
Consenting Parties under Article VI.B.2. shall relate only and be limited to the
lesser of (i) the total depth actually drilled or (ii) the objective depth or
Zone of which the parties were given notice under Article VI.B.1. (“Initial
Objective”). Such well shall not be Deepened beyond the Initial Objective
without first complying with this Article to afford the Non-Consenting Parties
the opportunity to participate in the Deepening operation.
     In the event any Consenting Party desires to drill or Deepen a Non-Consent
Well to a depth below the Initial Objective, such party shall give notice
thereof, complying with the requirements of Article VI.B.1., to all parties
(including Non-Consenting Parties). Thereupon, Articles VI.B.1. and 2. shall
apply and all parties receiving such notice shall have the tight to participate
or not participate in the Deepening of such well pursuant to said Articles
VI.B.1. and 2. If a Deepening operation is approved pursuant to such provisions,
and if any Non-Consenting Party elects to participate in the Deepening
operation, such Non-Consenting party shall pay or make reimbursement (as the
case may be) of the following costs and expenses:
          (a) If the proposal to Deepen is made prior to the Completion of such
well as a well capable of producing in paying quantities, such Non-Consenting
Party shall pay (or reimburse Consenting Parties for, as the case may be) that
share of costs and expenses incurred in connection with the drilling of said
well from the surface to the Initial Objective which Non-Consenting Party would
have paid had such Non-Consenting Party agreed to participate therein, plus the
Non-Consenting Party’s share of the cost of Deepening and of participating in
any further operations on the well in accordance with the other provisions of
this Agreement; provided, however, all costs for testing and Completion or
attempted Completion of the well incurred by Consenting Parties prior to the
point of actual operations to Deepen beyond the Initial Objective shall be for
the sole account of Consenting Parties.
          (b) If the proposal is made for a Non-Consent Well that has been
previously Completed as a well capable of producing in paying quantities, but is
no longer capable of producing in paying quantities, such Non-Consenting Party
shall pay (or reimburse Consenting Parties for, as the case may be) its
proportionate share of all costs of drilling, Completing, and equipping said
well from the surface to the Initial Objective, calculated in the manner
provided in paragraph (a) above, less those costs recouped by the Consenting
Parties from the sale of production from the well. The Non-Consenting Party
shall also pay its proportionate share of all costs of re-entering said well.
The Non-Consenting Parties’ proportionate part (based on the percentage of such
well Non-Consenting Party would have owned had it previously participated in
such Non-Consent Well) of the costs of salvable materials and equipment
remaining in the hole and salvable surface equipment used in connection with
such well shall be determined in accordance with Exhibit “C.” If the Consenting
Parties have recouped the cost of drilling, Completing, and equipping the well
at the time such Deepening operation is conducted, then a Non-Consenting Party
may participate in the Deepening of the well with no payment for costs incurred
prior to re-entering the well for Deepening.
          The foregoing shall not imply a right of any Consenting Party to
propose any Deepening for a Non-Consent Well prior to the drilling of such well
to its Initial Objective without the consent of the other Consenting Parties as
provided in Article VI.F.
     5. Sidetracking: Any party having the right to participate in a proposed
Sidetracking operation that does not own an interest in the affected wellbore at
the time of the notice shall, upon electing to participate, tender to the
wellbore owners its proportionate share (equal to its interest in the
Sidetracking operation) of the value of that portion of the existing wellbore to
be utilized as follows:
          (a) If the proposal is for Sidetracking an existing dry hole,
reimbursement shall be on the basis of the actual costs incurred in the initial
drilling of the well down to the depth at which the Sidetracking operation is
initiated.
          (b) If the proposal is for Sidetracking a well which has previously
produced, reimbursement shall be on the basis of such party’s proportionate
share of drilling and equipping costs incurred in the initial drilling of the
well down to the depth at which the Sidetracking operation is conducted,
calculated in the manner described in Article VI.B.4(b) above. Such party’s
proportionate share of the cost of the well’s salvable materials and equipment
down to the depth at which the Sidetracking operation is initiated shall be
determined in accordance with the provisions of Exhibit “C.”
     6. Order of Preference of Operations. Except as otherwise specifically
provided in this agreement, if any party desires to propose the conduct of an
operation that conflicts with a proposal that has been made by a party under
this Article VI, such party shall have fifteen (15) days from delivery of the
initial proposal, in the case of a proposal to drill a well or to perform an
operation on a well where no drilling rig is on location, or twenty-four
(24) hours, from delivery of the initial proposal, if a drilling rig is on
location for the well on which such operation is to be conducted, to deliver to
all parties entitled to participate in the proposed operation such party’s
alternative proposal, such alternate proposal to contain the same information
required to be included in the initial proposal. Each party receiving such
proposals shall elect by delivery of notice to Operator within five (5) days
after expiration of the proposal period, or within twenty-four (24) hours if a
drilling rig is on location for the well that is the subject of the proposals,
to participate in one of the competing proposals. Any Party not electing within
the time required shall be deemed not to have voted. The proposal receiving the
vote of parties owning the largest aggregate percentage interest of the parties
voting shall have priority over all other competing proposals; in the case of a
tie vote, the

 

--------------------------------------------------------------------------------

 

A.A.P.L. FORM 610 — MODEL FORM OPERATING AGREEMENT- 1989
initial proposal shall prevail. Operator shall deliver notice of such result to
all parties entitled to participate in the operation within five (5) days after
expiration of the election period (or within twenty-four (24) hours, if a
drilling rig is on location). Each party shall then have two (2) days (or
twenty-four (24) hours if a rig is on location) from receipt of such notice to
elect by delivery of notice to Operator to participate in such operation or to
relinquish interest in the affected well pursuant to the provisions of
Article VI.B.2.; failure by a party to deliver notice within such period shall
be deemed an election not to participate in the prevailing proposal.
     7. Conformity to Spacing Pattern. Notwithstanding the provisions of this
Article VI.B.2., it is agreed that no wells shall be proposed to be drilled to
or Completed in or produced from a Zone from which a well located elsewhere on
the Contract Area is producing, unless such well conforms to the then-existing
well spacing pattern for such Zone.
     8. Paying Wells. No party shall conduct any Reworking, Deepening, Plugging
Back, Completion, Recompletion, or Sidetracking operation under this agreement
with respect to any well then capable of producing in paying quantities except
with the consent of all parties that have not relinquished interests in the well
at the time of such operation.
C. Completion of Wells; Reworking and Plugging Back:
     1. Completion: Without the consent of all parties, no well shall be
drilled, Deepened or Sidetracked, except any well drilled, Deepened or
Sidetracked pursuant to the provisions of Article VI.B.2. of this agreement.
Consent to the drilling, Deepening or Sidetracking shall include:
     þ Option No. 1: All necessary expenditures for the drilling, Deepening or
Sidetracking, testing, Completing and equipping of the well, including necessary
tankage and/or surface facilities.
     o Option No. 2: All necessary expenditures for the drilling, Deepening or
Sidetracking and testing of the well. When such well has reached its authorized
depth, and all logs, cores and other tests have been completed, and the results
thereof furnished to the parties, Operator shall give immediate notice to the
Non-Operators having the right to participate in a Completion attempt whether or
not Operator recommends attempting to Complete the well, together with
Operator’s AFE for Completion costs if not previously provided. The parties
receiving such notice shall have forty-eight (48) hours (exclusive of Saturday,
Sunday and legal holidays) in which to elect by delivery of notice to Operator
to participate in a recommended Completion attempt or to make a Completion
proposal with an accompanying AFE. Operator shall deliver any such Completion
proposal, or any Completion proposal conflicting with Operator’s proposal, to
the other parties entitled to participate in such Completion in accordance with
the procedures specified in Article VI.B.6. Election to participate in a
Completion attempt shall include consent to all necessary expenditures for the
Completing and equipping of such well, including necessary tankage and/or
surface facilities but excluding any stimulation operation not contained on the
Completion AFE. Failure of any party receiving such notice to reply within the
period above fixed shall constitute an election by that party not to participate
in the cost of the Completion attempt; provided, that Article VI.B.6. shall
control in the case of conflicting Completion proposals. If one or more, but
less than all of the parties, elect to attempt a Completion, the provisions of
Article VI.B.2. hereof (the phrase “Reworking, Sidetracking, Deepening,
Recompleting or Plugging Back” as contained in Article VI.B.2. shall be deemed
to include “Completing”) shall apply to the operations thereafter conducted by
less than all parties; provided, however, that Article VI.B.2 shall apply
separately to each separate Completion or Recompletion attempt undertaken
hereunder, and an election to become a Non-Consenting Party as to one Completion
or Recompletion attempt shall not prevent a party from becoming a Consenting
Party in subsequent Completion or Recompletion attempts regardless whether the
Consenting Parties as to earlier Completions or Recompletions have recouped
their costs pursuant to Article VI.B.2.; provided further, that any recoupment
of costs by a Consenting Party shall be made solely from the production
attributable to the Zone in which the Completion attempt is made. Election by a
previous Non-Consenting Party to participate in a subsequent Completion or
Recompletion attempt shall require such party to pay its proportionate share of
the cost of salvable materials and equipment installed in the well pursuant to
the previous Completion or Recompletion attempt, insofar and only insofar as
such materials and equipment benefit the Zone in which such party participates
in a Completion attempt.
     2. Rework, Recomplete or Plug Back: No well shall be Reworked, Recompleted
or Plugged Back except a well Reworked, Recompleted, or Plugged Back pursuant to
the provisions of Article VI.B.2. of this agreement. Consent to the Reworking,
Recompleting or Plugging Back of a well shall include all necessary expenditures
in conducting such operations and Completing and equipping of said well,
including necessary tankage and/or surface facilities.
D. Other Operations:
          Operator shall not undertake any single project reasonably estimated
to require an expenditure in excess of ___Twenty-five thousand Dollars ($
25,000.00) except in connection with the drilling, Sidetracking, Reworking,
Deepening, Completing, Recompleting or Plugging Back of a well that has been
previously authorized by or pursuant to this agreement; provided, however, that,
in case of explosion, fire, flood or other sudden emergency, whether of the same
or different nature, Operator may take such steps and incur such expenses as in
its opinion are required to deal with the emergency to safeguard life and
property but Operator, as promptly as possible, shall report the emergency to
the other parties. If Operator prepares an AFE for its own use, Operator shall
furnish any Non-Operator so requesting an information copy thereof for any
single project costing in excess of Twenty-five thousand Dollars ($ 25,000.00).
Any party who has not relinquished its interest in a well shall have the right
to propose that Operator perform repair work or undertake the installation of
artificial lift equipment or ancillary production facilities such as salt water
disposal wells or to conduct additional work with respect to a well drilled
hereunder or other similar project (but not including the installation of
gathering lines or other transportation or marketing facilities, the
installation of which shall be governed by separate agreement between the
Parties) reasonably estimated to require an expenditure in excess of the amount
first set forth above in this Article VI.D. (except in connection with an
operation required to be proposed under Articles VI.B.1. or VI.C.1. Option
No. 2, which shall be governed exclusively by those Articles). Operator shall
deliver such proposal to all parties entitled to participate therein. If within
thirty (30) days thereof Operator secures the written consent of any party or
parties owning at least 50 % of the interests of the parties entitled to
participate in such operation, each party having the right to participate in
such project shall be bound by the terms of such proposal and shall be obligated
to pay its proportionate share of the costs of the proposed project as if it had
consented to such project pursuant to the terms of the proposal.

E. Abandonment of Wells:
     1. Abandonment of Dry Holes: Except for any well drilled or Deepened
pursuant to Article VI.B.2., any well which has been drilled or Deepened under
the terms of this agreement and is proposed to be completed as a dry hole shall
not be

A.A.P.L. FORM 610 — MODEL FORM OPERATING AGREEMENT- 1989
plugged and abandoned without the consent of all parties. Should Operator, after
diligent effort, be unable to contact any party, or should any party fail to
reply within forty-eight (48) hours (exclusive of Saturday, Sunday and legal
holidays) after delivery of notice of the proposal to plug and abandon such
well, such party shall be deemed to have consented to the proposed abandonment.
All such wells shall be plugged and abandoned in accordance with applicable
regulations and at the cost, risk and expense of the parties who participated in
the cost of drilling or Deepening such well. Any Party who objects to plugging
and abandoning such well by notice delivered to Operator within forty-eight
(48) hours (exclusive of Saturday, Sunday and legal holidays) after delivery of
notice of the proposed plugging shall take over the well as of the end of such
forty-eight (48) hour notice period and conduct further operations in search of
Oil and/or Gas subject to the provisions of Article Vl.B.; failure of such party
to provide proof reasonably satisfactory to Operator of its financial capability
to conduct such operations or to take over the well within such period or
thereafter to conduct operations on such well or plug and abandon such well
shall entitle Operator to retain or take possession of the well and plug and
abandon the well. The party taking over the well shall indemnify Operator (if
Operator is an abandoning party) and the other abandoning parties against
liability for any further operations conducted on such well except for the costs
of plugging and abandoning the well and restoring the surface, for which the
abandoning parties shall remain proportionately liable.
     2. Abandonment of Wells That Have Produced: Except for any well in which a
Non-Consent operation has been conducted hereunder for which the Consenting
Parties have not been fully reimbursed as herein provided, any well which has
been completed as a producer shall not be plugged and abandoned without the
consent of all parties. If all parties consent to such abandonment, the well
shall be plugged and abandoned in accordance with applicable regulations and at
the cost, risk and expense of all the parties hereto. Failure of a party to
reply within sixty (60) days of delivery of notice of proposed abandonment shall
be deemed an election to consent to the proposal. If, within sixty (60) days
after delivery of notice of the proposed abandonment of any well, all parties do
not agree to the abandonment of such well, those wishing to continue its
operation from the Zone then open to production shall be obligated to take over
the well as of the expiration of the applicable notice period and shall
indemnify Operator (if Operator is an abandoning party) and the other abandoning
parties against liability for any further operations on the well conducted by
such parties. Failure of such party or parties to provide proof reasonably
satisfactory to Operator of their financial capability to conduct such
operations or to take over the well within the required period or thereafter to
conduct operations on such well shall entitle Operator to retain or take
possession of such well and plug and abandon the well.
     Parties taking over a well as provided herein shall tender to each of the
other parties its proportionate share of the value of the well’s salvable
material and equipment, determined in accordance with the provisions of Exhibit
“C”, less the estimated cost of salvaging and the estimated cost of plugging and
abandoning and restoring the surface; provided, however, that in the event the
estimated plugging and abandoning and surface restoration costs and the
estimated cost of salvaging are higher than the value of the well’s salvable
material and equipment, each of the abandoning parties shall tender to the
parties continuing operations their proportionate shares of the estimated excess
cost. Each abandoning party shall assign to the non-abandoning parties, without
warranty, express or implied, as to title or as to quantity, or fitness for use
of the equipment and material, all of its interest in the wellbore of the well
and related equipment, together with its interest in the Leasehold insofar and
only insofar as such Leasehold covers the right to obtain production from that
wellbore in the Zone then open to production. If the interest of the abandoning
party is or includes an Oil and Gas Interest, such party shall execute and
deliver to the non-abandoning party or parties an oil and gas lease, limited to
the wellbore and the Zone then open to production, for a term of one (1) year
and so long thereafter as Oil and/or Gas is produced from the Zone covered
thereby, such lease to be on the form attached as Exhibit “B”. The assignments
or leases so limited shall encompass the Drilling Unit upon which the well is
located. The payments by, and the assignments or leases to, the assignees shall
be in a ratio based upon the relationship of their respective percentage of
participation in the Contract Area to the aggregate of the percentages of
participation in the Contract Area of all assignees. There shall be no
readjustment of interests in the remaining portions of the Contract Area.
     Thereafter, abandoning parties shall have no further responsibility,
liability, or interest in the operation of or production from the well in the
Zone then open other than the royalties retained in any lease made under the
terms of this Article. Upon request, Operator shall continue to operate the
assigned well for the account of the non-abandoning parties at the rates and
charges contemplated by this agreement, plus any additional cost and charges
which may arise as the result of the separate ownership of the assigned well.
Upon proposed abandonment of the producing Zone assigned or leased, the assignor
or lessor shall then have the option to repurchase its prior interest in the
well (using the same valuation formula) and participate in further operations
therein subject to the provisions hereof.
     3. Abandonment of Non-Consent Operations: The provisions of Article VI.E.1.
or VI.E.2. above shall be applicable as between Consenting Parties in the event
of the proposed abandonment of any well excepted from said Articles; provided,
however, no well shall be permanently plugged and abandoned unless and until all
parties having the right to conduct further operations therein have been
notified of the proposed abandonment and afforded the opportunity to elect to
take over the well in accordance with the provisions of this Article VI.E.; and
provided further, that Non-Consenting Parties who own an interest in a portion
of the well shall pay their proportionate shares of abandonment and surface
restoration costs for such well as provided in Article VI.B.2.(b).
F. Termination of Operations:
          Upon the commencement of an operation for the drilling, Reworking,
Sidetracking, Plugging Back, Deepening, testing, Completion or plugging of a
well, including but not limited to the Initial Well, such operation shall not be
terminated without consent of parties bearing 50 % of the costs of such
operation; provided, however, that in the event granite or other practically
impenetrable substance or condition in the hole is encountered which tenders
further operations impractical, Operator may discontinue operations and give
notice of such condition in the manner provided in Article Vl.B. 1, and the
provisions of Article VI.B. or VI.E. shall thereafter apply to such operation,
as appropriate.

ARTICLE VII.
EXPENDITURES AND LIABILITY OF PARTIES
A. 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 Article VII.B.
are given to secure only the debts of each severally, and no party shall have
any liability to third parties hereunder to satisfy the default of any other
party in the payment of any expense or obligation hereunder. It is not the
intention of the parties to create, nor shall this agreement be construed as
creating, a mining or other partnership, joint venture, agency relationship or
association, or to render the parties liable as partners, co-venturers, or
principals. In their relations with each other under this agreement, the parties
shall not be considered fiduciaries or to have established a confidential
relationship but rather shall be free to act on an arm’s-length basis in
accordance with their own respective self-interest, subject, however, to the
obligation of the parties to act in good faith in their dealings with each other
with respect to activities hereunder.

 

--------------------------------------------------------------------------------

 

A.A.P.L. FORM 610 — MODEL FORM OPERATING AGREEMENT- 1989
B. Liens and Security Interests:
     Each party grants to the other parties hereto a lien upon any interest it
now owns or hereafter acquires in Oil and Gas Leases and Oil and Gas Interests
in the Contract Area, and a security interest and/or purchase money security
interest in any interest it now owns or hereafter acquires in the personal
property and fixtures on or used or obtained for use in connection therewith, to
secure performance of all of its obligations under this agreement including but
not limited to payment of expense, interest and fees, the proper disbursement of
all monies paid hereunder, the assignment or relinquishment of interest in Oil
and Gas Leases as required hereunder, and the proper performance of operations
hereunder. Such lien and security interest granted by each party hereto shall
include such party’s leasehold interests, working interests, operating rights,
and royalty and overriding royalty interests in the Contract Area now owned or
hereafter acquired and in lands pooled or unitized therewith or otherwise
becoming subject to this agreement, the Oil and Gas when extracted therefrom and
equipment situated thereon or used or obtained for use in connection therewith
(including, without limitation, all wells, tools, and tubular goods), and
accounts (including, without limitation, accounts arising from gas imbalances or
from the sale of Oil and/or Gas at the wellhead), contract rights, inventory and
general intangibles relating thereto or arising therefrom, and all proceeds and
products of the foregoing.
     To perfect the lien and security agreement provided herein, each party
hereto shall execute and acknowledge the recording supplement and/or any
financing statement prepared and submitted by any party hereto in conjunction
herewith or at any time following execution hereof, and Operator is authorized
to file this agreement or the recording supplement executed herewith as a lien
or mortgage in the applicable real estate records and as a financing statement
with the proper officer under the Uniform Commercial Code in the state in which
the Contract Area is situated and such other states as Operator shall deem
appropriate to perfect the security interest granted hereunder. Any party may
file this agreement, the recording supplement executed herewith, or such other
documents as it deems necessary as a lien or mortgage in the applicable real
estate records and/or a financing statement with the proper officer under the
Uniform Commercial Code.
     Each party represents and warrants to the other parties hereto that the
lien and security interest granted by such party to the other parties shall be a
first and prior lien, and each party hereby agrees to maintain the priority of
said lien and security interest against all persons acquiring an interest in Oil
and Gas Leases and Interests covered by this agreement by, through or under such
party. All parties acquiring an interest in Oil and Gas Leases and Oil and Gas
Interests covered by this agreement, whether by assignment, merger, mortgage,
operation of law, or otherwise, shall be deemed to have taken subject to the
lien and security interest granted by this Article VII.B. as to all obligations
attributable to such interest hereunder whether or not such obligations arise
before or after such interest is acquired.
     To the extent that parties have a security interest under the Uniform
Commercial Code of the state in which the Contract Area is situated, they 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 a party 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.
In addition, upon default by any party in the payment of its share of expenses,
interests or fees, or upon the improper use of funds by the Operator, the other
parties shall have the right, without prejudice to other rights or remedies, to
collect from the purchaser the proceeds from the sale of such defaulting party’s
share of Oil and Gas until the amount owed by such party, plus interest as
provided in Exhibit “C”, has been received, and shall have the right to offset
the amount owed against the proceeds from the sale of such defaulting party’s
share of Oil and Gas. All purchasers of production may rely on a notification of
default from the non-defaulting party or parties stating the amount due as a
result of the default, and all parties waive any recourse available against
purchasers for releasing production proceeds as provided in this paragraph.
     If any party fails to pay its share of cost within one hundred twenty
(120) days after rendition of a statement therefor by Operator, the
non-defaulting parties, including Operator, shall, upon request by Operator, pay
the unpaid amount in the proportion that the interest of each such party bears
to the interest of all such parties. The amount paid by each party so paying its
share of the unpaid amount shall be secured by the liens and security rights
described in Article VII.B., and each paying party may independently pursue any
remedy available hereunder or otherwise.
     If any party does not perform all of its obligations hereunder, and the
failure to perform subjects such party to foreclosure or execution proceedings
pursuant to the provisions of this agreement, to the extent allowed by governing
law, the defaulting party waives any available right of redemption from and
after the date of judgment, any required valuation or appraisement of the
mortgaged or secured property prior to sale, any available right to stay
execution or to require a marshalling of assets and any required bond in the
event a receiver is appointed. In addition, to the extent permitted by
applicable law, each party hereby grants to the other parties a power of sale as
to any property that is subject to the lien and security rights granted
hereunder, such power to be exercised in the manner provided by applicable law
or otherwise in a commercially reasonable manner and upon reasonable notice.
     Each party agrees that the other parties shall be entitled to utilize the
provisions of Oil and Gas lien law or other lien law of any state in which the
Contract Area is situated to enforce the obligations of each party hereunder.
Without limiting the generality of the foregoing, to the extent permitted by
applicable law, Non-Operators agree that Operator may invoke or utilize the
mechanics’ or materialmen’s lien law of the state in which the Contract Area is
situated in order to secure the payment to Operator of any sum due hereunder for
services performed or materials supplied by Operator.
C. Advances:
     Operator, at its election, shall have the right from time to time to demand
and receive from one or more of 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 20th day of the next preceding month. 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
as provided in Exhibit “C” 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.
D. Defaults and Remedies:
     If any party fails to discharge any financial obligation under this
agreement, including without limitation the failure to make any advance under
the preceding Article VII.C. or any other provision of this agreement, within
the period required for such payment hereunder, then in addition to the remedies
provided in Article VII.B. or elsewhere in this agreement, the remedies
specified below shall he applicable. For purposes of this Article VII.D., all
notices and elections shall be delivered

 

--------------------------------------------------------------------------------

 

A.A.P.L. FORM 610 — MODEL FORM OPERATING AGREEMENT- 1989
only by Operator, except that Operator shall deliver any such notice and
election requested by a non-defaulting Non-Operator, and when Operator is the
party in default, the applicable notices and elections can be delivered by any
Non-Operator. Election of any one or more of the following remedies shall not
preclude the subsequent use of any other remedy specified below or otherwise
available to a non-defaulting party.
     1. Suspension of Rights: Any party may deliver to the party in default a
Notice of Default, which shall specify the default, specify the action to be
taken to cure the default, and specify that failure to take such action will
result in the exercise of one or more of the remedies provided in this Article.
If the default is not cured within thirty (30) days of the delivery of such
Notice of Default, all of the rights of the defaulting party granted by this
agreement may upon notice be suspended until the default is cured, without
prejudice to the right of the non-defaulting party or parties to continue to
enforce the obligations of the defaulting party previously accrued or thereafter
accruing under this agreement. If Operator is the party in default, the
Non-Operators shall have in addition the right, by vote of Non-Operators owning
a majority in interest in the Contract Area after excluding the voting interest
of Operator, to appoint a new Operator effective immediately. The rights of a
defaulting party that may be suspended hereunder at the election of the
non-defaulting parties shall include, without limitation, the right to receive
information as to any operation conducted hereunder during the period of such
default, the right to elect to participate in an operation proposed under
Article VI.B. of this agreement, the right to participate in an operation being
conducted under this agreement even if the party has previously elected to
participate in such operation, and the right to receive proceeds of production
from any well subject to this agreement.
     2. Suit for Damages: Non-defaulting parties or Operator for the benefit of
non-defaulting parties may sue (at joint account expense) to collect the amounts
in default, plus interest accruing on the amounts recovered from the date of
default until the date of collection at the rate specified in Exhibit “C”
attached hereto. Nothing herein shall prevent any party from suing any
defaulting party to collect consequential damages accruing to such party as a
result of the default.
     3. Deemed Non-Consent: The non-defaulting party may deliver a written
Notice of Non-Consent Election to the defaulting party at any time after the
expiration of the thirty-day cure period following delivery of the Notice of
Default, in which event if the billing is for the drilling of a new well or the
Plugging Back, Sidetracking, Reworking or Deepening of a well which is to be or
has been plugged as a dry hole, or for the Completion or Recompletion of any
well, the defaulting party will be conclusively deemed to have elected not to
participate in the operation and to be a Non-Consenting Party with respect
thereto under Article VI.B. or VI.C., as the case may be, to the extent of the
costs unpaid by such party, notwithstanding any election to participate
theretofore made. If election is made to proceed under this provision, then the
non-defaulting parties may not elect to sue for the unpaid amount pursuant to
Article VII.D.2.
     Until the delivery of such Notice of Non-Consent Election to the defaulting
party, such party shall have the right to cure its default by paying its unpaid
share of costs plus interest at the rate set forth in Exhibit “C,” provided,
however, such payment shall not prejudice the rights of the non-defaulting
parties to pursue remedies for damages incurred by the non-defaulting parties as
a result of the default. Any interest relinquished pursuant to this
Article VII.D.3. shall be offered to the non-defaulting parties in proportion to
their interests, and the non-defaulting parties electing to participate in the
ownership of such interest shall be required to contribute their shares of the
defaulted amount upon their election to participate therein
     4. Advance Payment: If a default is not cured within thirty (30) days of
the delivery of a Notice of Default, Operator, or Non-Operators if Operator is
the defaulting party, may thereafter require advance payment from the defaulting
party of such defaulting party’s anticipated share of any item of expense for
which Operator, or Non-Operators, as the case may be, would be entitled to
reimbursement under any provision of this agreement, whether or not such expense
was the subject of the previous default. Such right includes, but is not limited
to, the right to require advance payment for the estimated costs of drilling a
well or Completion of a well as to which an election to participate in drilling
or Completion has been made. If the defaulting party fails to pay the required
advance payment, the non-defaulting parties may pursue any of the remedies
provided in this Article VILD. or any other default remedy provided elsewhere in
this agreement. Any excess of funds advanced remaining when the operation is
completed and all costs have been paid shall be promptly returned to the
advancing party.
     5. Costs and Attorneys’ Fees. In the event any party is required to bring
legal proceedings to enforce any financial obligation of a party hereunder, the
prevailing party in such action shall be entitled to recover all court costs,
costs of collection, and a reasonable attorney’s fee, which the lien provided
for herein shall also secure.
E. Rentals, Shut-in Well Payments and Minimum Royalties:
     Rentals, shut-in well payments and minimum royalties which may be required
under the terms of any lease shall be paid by the party or parties who subjected
such lease to this agreement at its or their expense. In the event two or more
parties own and have contributed interests in the same lease to this agreement,
such parties may designate one of such parties to make said payments for and on
behalf of all such parties. Any party may request, and shall be entitled to
receive, proper evidence of all such payments. 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 in accordance
with the provisions of Article IV.B.2.
     Operator shall notify Non-Operators of the anticipated completion of a
shut-in well, or the shutting in or return to production of a producing well, at
least five (5) days (excluding Saturday, Sunday and legal holidays) prior to
taking such action, or at the earliest opportunity permitted by circumstances,
but assumes no liability for failure to do so. In the event of failure by
Operator to so notify Non-Operators, the loss of any lease contributed hereto by
Non-Operators for failure to make timely payments of any shut-in well payment
shall be borne jointly by the parties hereto under the provisions of Article
lV.B.3.
F. 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. Prior to the
rendition date, each Non-Operator shall furnish Operator information as to
burdens (to include, but not be limited to, royalties, overriding royalties and
production payments) on Leases and Oil and Gas Interests contributed by such
Non-Operator. If the assessed valuation of any Lease is reduced by reason of its
being subject to outstanding excess royalties, overriding royalties or
production payments, the reduction in ad valorem taxes resulting therefrom shall
inure to the benefit of the owner or owners of such Lease, and Operator shall
adjust the charge to such owner or owners so as to reflect the benefit of such
reduction. If the ad valorem taxes are based in whole or in part upon separate
valuations of each party’s working interest, then notwithstanding anything to
the contrary herein, charges to the joint account shall be made and paid by the
parties hereto in accordance with the tax value generated by each party’s
working interest. Operator shall bill the other parties for their proportionate
shares of all tax payments in the manner provided in Exhibit “C”.

 

--------------------------------------------------------------------------------

 

A.A.P.L. FORM 610 — MODEL FORM OPERATING AGREEMENT- 1989
     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 all parties agree to abandon the
protest prior to final determination. During the pendency of administrative or
judicial proceedings, Operator may elect to pay, under protest, all such taxes
and any interest and penalty. When any such protested assessment shall have been
finally determined, Operator shall pay the tax for the joint account, together
with any interest and penalty accrued, and the total cost shall then be assessed
against the parties, and be paid by them, as provided in Exhibit “C.”
     Each party shall pay or cause to be paid all production, severance, excise,
gathering and other taxes imposed upon or with respect to the production or
handling of such party’s share of Oil and Gas produced under the terms of this
agreement.
ARTICLE VIII.
ACQUISITION, MAINTENANCE OR TRANSFER OF INTEREST
A. Surrender of Leases:
     The Leases covered by this agreement, insofar as they embrace acreage in
the Contract Area, shall not be surrendered in whole or in part unless all
parties consent thereto.
     However, should any party desire to surrender its interest in any Lease or
in any portion thereof, such party shall give written notice of the proposed
surrender to all parties, and the parties to whom such notice is delivered shall
have thirty (30) days after delivery of the notice within which to notify the
party proposing the surrender whether they elect to consent thereto. Failure of
a party to whom such notice is delivered to reply within said 30-day period
shall constitute a consent to the surrender of the Leases described in the
notice. If all parties do not agree or consent thereto, the party desiring to
surrender shall assign, without express or implied warranty of title, all of its
interest in such Lease, or portion thereof, and any well, material and equipment
which may be located thereon and any rights in production thereafter secured, to
the parties not consenting to such surrender. If the interest of the assigning
party is or includes an Oil and Gas Interest, the assigning party shall execute
and deliver to the party or parties not consenting to such surrender an oil and
gas lease covering such Oil and Gas Interest for a term of one (1) year and so
long thereafter as Oil and/or Gas is produced from the land covered thereby,
such lease to be on the form attached hereto as Exhibit “B”. Upon such
assignment or lease, the assigning party shall be relieved from all obligations
thereafter accruing, but not theretofore accrued, with respect to the interest
assigned or leased and the operation of any well attributable thereto, and the
assigning party shall have no further interest in the assigned or leased
premises and its equipment and production other than the royalties retained in
any lease made under the terms of this Article. The party assignee or lessee
shall pay to the party assignor or lessor the reasonable salvage value of the
latter’s interest in any well’s salvable materials and equipment attributable to
the assigned or leased acreage. The value of all salvable materials and
equipment shall be determined in accordance with the provisions of Exhibit “C”,
less the estimated cost of salvaging and the estimated cost of plugging and
abandoning and restoring the surface. If such value is less than such costs,
then the party assignor or lessor shall pay to the party assignee or lessee the
amount of such deficit. If the assignment or lease is in favor of more than one
party, the interest shall be shared by such parties in the proportions that the
interest of each bears to the total interest of all such parties. If the
interest of the parties to whom the assignment is to be made varies according to
depth, then the interest assigned shall similarly reflect such variances.
     Any assignment, lease or surrender made under this provision shall not
reduce or change the assignor’s, lessor’s or surrendering party’s interest as it
was immediately before the assignment, lease or surrender in the balance of the
Contract Area; and the acreage assigned, leased or surrendered, and subsequent
operations thereon, shall not thereafter be subject to the terms and provisions
of this agreement but shall be deemed subject to an Operating Agreement in the
form of this agreement.
B. Renewal or Extension of Leases:
     If any party secures a renewal or replacement of an Oil and Gas Lease or
Interest subject to this agreement, then all other parties shall be notified
promptly upon such acquisition or, in the case of a replacement Lease taken
before expiration of an existing Lease, promptly upon expiration of the existing
Lease. The parties notified shall have the right for a period of thirty
(30) days following delivery of such notice in which to elect to participate in
the ownership of the renewal or replacement Lease, insofar as such Lease affects
lands within the Contract Area, by paying to the party who acquired it their
proportionate shares of the acquisition cost 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 party who
participates in the purchase of a renewal or replacement Lease shall be given an
assignment of its proportionate interest therein by the acquiring party.
     If some, but less than all, of the parties elect to participate in the
purchase of a renewal or replacement Lease, it shall be owned by the parties who
elect to participate therein, in a ratio based upon the relationship of their
respective percentage of participation in the Contract Area to the aggregate of
the percentages of participation in the Contract Area of all parties
participating in the purchase of such renewal or replacement Lease. The
acquisition of a renewal or replacement Lease by any or all of the parties
hereto shall not cause a readjustment of the interests of the parties stated in
Exhibit “A”, but any renewal or replacement Lease in which less than all parties
elect to participate shall not be subject to this agreement but shall be deemed
subject to a separate Operating Agreement in the form of this agreement.
     If the interests of the parties in the Contract Area vary according to
depth, then their right to participate proportionately in renewal or replacement
Leases and their right to receive an assignment of interest shall also reflect
such depth variances.
     The provisions of this Article shall apply to renewal or replacement 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 replacement
Lease taken before the expiration of its predecessor Lease, or taken or
contracted for or becoming effective within six (6) months after the expiration
of the existing Lease, shall be subject to this provision so long as this
agreement is in effect at the time of such acquisition or at the time the
renewal or replacement Lease becomes effective; 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 or replacement Lease and shall not be
subject to the provisions of this agreement.
     The provisions in this Article shall also be applicable to extensions of
Oil and Gas Leases.
C. Acreage or Cash Contributions:
     While this agreement is in force, if any party contracts for a contribution
of cash towards the drilling of a well or any other operation on the Contract
Area, such contribution shall be paid to the party who conducted the drilling or
other operation and shall be applied by it against the cost of such drilling or
other operation. If the contribution be in the form of acreage, the party to
whom the contribution is made shall promptly render an assignment of the
acreage, without warranty of title, to the Drilling Parties in the proportions
said Drilling Parties shared the cost of drilling the well. Such acreage shall
become a separate Contract Area and, to the extent possible, be governed by
provisions identical to this agreement. Each party shall promptly notify all
other parties of any acreage or cash contributions it may obtain in support of
any well or any other operation on the Contract Area The above provisions shall
also be applicable to optional rights to earn acreage outside the Contract Area
which are in support of well drilled inside the Contract Area.

A.A.P.L. FORM 610 — MODEL FORM OPERATING AGREEMENT- 1989
     If any party contracts for any consideration relating to disposition of
such party’s share of substances produced hereunder, such consideration shall
not be deemed a contribution as contemplated in this Article VIII.C.
D. Assignment; Maintenance of Uniform Interest:
     For the purpose of maintaining uniformity of ownership in the Contract Area
in the Oil and Gas Leases, Oil and Gas Interests, wells, equipment and
production covered by this agreement no party shall sell, encumber, transfer or
make other disposition of its interest in the Oil and Gas Leases and Oil and Gas
Interests embraced within the Contract Area or in wells, equipment and
production unless such disposition covers either::
     1. the entire interest of the party in all Oil and Gas Leases, Oil and Gas
Interests, wells, equipment and production; or
     2. an equal undivided percent of the party’s present interest in all Oil
and Gas Leases, Oil and Gas Interests, wells, equipment and production in the
Contract Area.
     Every 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, and any transferee of an ownership
interest in any Oil and Gas Lease or Interest shall be deemed a party to this
agreement as to the interest conveyed from and after the effective date of the
transfer of ownership; provided, however, that the other parties shall not be
required to recognize any such sale, encumbrance, transfer or other disposition
for any purpose hereunder until thirty (30) days after they have received a copy
of the instrument of transfer or other satisfactory evidence thereof in writing
from the transferor or transferee. No assignment or other disposition of
interest by a party shall relieve such party of obligations previously incurred
by such party hereunder with respect to the interest transferred, including
without limitation the obligation of a party to pay all costs attributable to an
operation conducted hereunder in which such party has agreed to participate
prior to making such assignment, and the lien and security interest granted by
Article VII.B. shall continue to burden the interest transferred to secure
payment of any such obligations.
     If, at any time the interest of any party is divided among and owned by
four or more co-owners, Operator, at its discretion, may require such co-owners
to appoint a single trustee or agent with full authority to receive notices,
approve expenditures, receive billings for and approve and pay such party’s
share of the joint expenses, and to deal generally with, and with power to bind,
the co-owners of such party’s interest within the scope of the operations
embraced in this agreement; however, all such co-owners shall have the right to
enter into and execute all contracts or agreements for the disposition of their
respective shares of the Oil and Gas produced from the Contract Area and they
shall have the right to receive, separately, payment of the sale proceeds
thereof.
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.
ARTICLE IX.
INTERNAL REVENUE CODE ELECTION
     If, for federal income tax purposes, this agreement and the operations
hereunder are regarded as a partnership, and if the parties have not otherwise
agreed to form a tax partnership pursuant to Exhibit “G” or other agreement
between them, each party thereby affected elects to be excluded from the
application of all of the provisions of Subchapter “K”, Chapter 1, Subtitle “A”
of the Internal Revenue Code of 1986, as amended (“Code”), as permitted and
authorized by Section 761 of the Code and the regulations promulgated
thereunder. Operator is authorized and directed to execute on behalf of each
party hereby affected such evidence of this election as may be required by the
Secretary of the Treasury of the United States or the Federal Internal Revenue
Service, including specifically, but not by way of limitation, all of the
returns, statements, and the data required by Treasury Regulations §1.761.
Should there be any requirement that each party hereby affected give further
evidence of this election, each such party shall execute such documents and
furnish such other evidence as may be required by the Federal Internal Revenue
Service or as may be necessary to evidence this election. No such party shall
give any notices or take any other action inconsistent with the election made
hereby. If any present or future income tax laws of the state or states in which
the Contract Area is located or any future income tax laws of the United States
contain provisions similar to those in Subchapter “K”, Chapter 1, Subtitle “A”,
of the Code, under which an election similar to that provided by Section 761 of
the Code is permitted, each party hereby affected shall make such election as
may be permitted or required by such laws. In making the foregoing election,
each such party states that the income derived by such party from operations
hereunder can be adequately determined without the computation of partnership
taxable income.
ARTICLE X.
CLAIMS AND LAWSUITS
     Operator may settle any single uninsured third party damage claim or suit
arising from operations hereunder if the expenditure does not exceed twenty-five
thousand Dollars ($25,000.00) and if the payment is in complete settlement of
such claim or suit. If the amount required for settlement exceeds the above
amount, the parties hereto shall assume and take over the further handling of
the claim or suit, unless such authority is delegated to Operator. All costs and
expenses of handling, settling, or otherwise discharging such claim or suit
shall be at the joint expense of the parties participating in the operation from
which the claim or suit arises. If a claim is made against any party or if any
party is sued on account of any matter arising from operations hereunder over
which such individual has no control because of the rights given Operator by
this agreement, such party shall immediately notify all other parties, and the
claim or suit shall be treated as any other claim or suit involving operations
hereunder.

ARTICLE XI.
FORCE MAJEURE
     If any party is rendered unable, wholly or in part, by force majeure to
carry out its obligations under this agreement, other than the obligation to
indemnify or make money payments or furnish security, that party shall give to
all other parties prompt written notice of the force majeure with reasonably
full particulars concerning it; thereupon, the obligations of the party giving
the notice, so far as they are affected by the force majeure, shall be suspended
during, but no longer than, the continuance of the force majeure. The term
“force majeure,” as here employed, shall mean an act of God, strike, lockout, or
other industrial disturbance, act of the public enemy, war, blockade, public
riot, lightning, fire, storm, flood or other act of nature, explosion,
governmental action, governmental delay, restraint or inaction, unavailability
of equipment, and any other cause, whether of the kind specifically enumerated
above or otherwise, which is not reasonably within the control of the party
claiming suspension.
     The affected party shall use all reasonable diligence to remove the force
majeure situation as quickly as practicable. The requirement that any force
majeure shall be remedied with all reasonable dispatch shall not require the
settlement of strikes, lockouts, or other labor difficulty by the party
involved, contrary to its wishes; how all such difficulties shall be handled
shall be entirely within the discretion of the party concerned.
ARTICLE XII.
NOTICES
     All notices authorized or required between the parties by any of the
provisions of this agreement, unless otherwise specifically provided, shall be

telegram, telex, telecopier or any other form of facsimile, postage or charges
prepaid, and addressed to such parties at the addresses listed on Exhibit “A.”
All telephone or oral notices permitted by this agreement shall be confirmed
immediately thereafter by written notice. The originating notice given under any
provision hereof shall be deemed delivered only when received by the party to
whom such notice is directed, and the time for such party to deliver any notice
in response thereto shall run from the date the originating notice is received.
“Receipt” for purposes of this agreement with respect to written notice
delivered hereunder shall be actual delivery of the notice to the address of the
party to be notified specified in accordance with this agreement, or to the
telecopy, facsimile or telex machine of such party. The second or any responsive
notice shall be deemed delivered when deposited in the United States mail or at
the office of the courier or telegraph service, or upon transmittal by telex,
telecopy or facsimile, or when personally delivered to the party to be notified,
provided, that when response is required within 24 or 48 hours, such response
shall be given orally or by telephone, telex, telecopy or other facsimile within
such period. 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. If
a party is not available to receive notice orally or by telephone when a party
attempts to deliver a notice required to be delivered within 24 or 48 hours, the
notice may be delivered in writing by any other method specified herein and
shall be deemed delivered in the same manner provided above for any responsive
notice.
ARTICLE XIII

hereunder, in the event a memorandum of this Operating Agreement has been filed

notice of termination as to Operator’s interest, upon request of Operator, if
Operator has satisfied all its financial obligations.
ARTICLE XIV.

A.A.P.L. FORM 610 — MODEL FORM OPERATING AGREEMENT- 1989
orders promulgated under such laws in reference to oil, gas and mineral
operations, including the location, operation, or production of wells, on tracts
offsetting or adjacent to the Contract Area.
     With respect to the 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 Federal Energy Regulatory Commission or predecessor or
successor agencies to the extent such interpretation or application was made in
good faith and does not constitute gross negligence. Each Non-Operator further
agrees to reimburse Operator for such Non-Operator’s share of production or any
refund, fine, levy or other governmental sanction that Operator may be required
to pay as a result of such an incorrect interpretation or application, together
with interest and penalties thereon owing by Operator as a result of such
incorrect interpretation or application.
ARTICLE XV.
MISCELLANEOUS
A. Execution:
     This agreement shall be binding upon each Non-Operator when this agreement
or a counterpart thereof has been executed by such Non-Operator and Operator
notwithstanding that this agreement is not then or thereafter executed by all of
the parties to which it is tendered or which are listed on Exhibit “A” as owning
an interest in the Contract Area or which own, in fact, an interest in the
Contract Area. Operator may, however, by written notice to all Non-Operators who
have become bound by this agreement as aforesaid, given at any time prior to the
actual spud date of the Initial Well but in no event later than five days prior
to the date specified in Article VI.A. for commencement of the Initial Well,
terminate this agreement if Operator in its sole discretion determines that
there is insufficient participation to justify commencement of drilling
operations. In the event of such a termination by Operator, all further
obligations of the parties hereunder shall cease as of such termination. In the
event any Non-Operator has advanced or prepaid any share of drilling or other
costs hereunder, all sums so advanced shall be returned to such Non-Operator
without interest. In the event Operator proceeds with drilling operations for
the Initial Well without the execution hereof by all persons listed on Exhibit
“A” as having a current working interest in such well, Operator shall indemnify
Non-Operators with respect to all costs incurred for the Initial Well which
would have been charged to such person under this agreement if such person had
executed the same and Operator shall receive all revenues which would have been
received by such person under this agreement if such person had executed the
same.
B. Successors and Assigns:
     This agreement shall be binding upon and shall inure to the benefit of the
parties hereto and their respective heirs, devisees, legal representatives,
successors and assigns, and the terms hereof shall be deemed to run with the
Leases or Interests included within the Contract Area.
C. Counterparts:
     This instrument may be executed in any number of counterparts, each of
which shall be considered an original for all purposes.
D. Severability:
     For the purposes of assuming or rejecting this agreement as an executory
contract pursuant to federal bankruptcy laws, this agreement shall not be
severable, but rather must be assumed or rejected in its entirety, and the
failure of any party to this agreement to comply with all of its financial
obligations provided herein shall be a material default.

development, operation, protection and maintenance of the Joint Property.
“Joint Account” shall mean the account showing the charges paid and credits
received in the conduct of the Joint Operations and which are to be shared by
the Parties.
“Operator” shall mean the party designated to conduct the Joint Operations.
“Non-Operators” shall mean the Parties to this agreement other than the
Operator.
“Parties” shall mean Operator and Non-Operators.
“First Level Supervisors” shall mean those employees whose primary function in
Joint Operations is the direct supervision of other employees and/or contract
labor directly employed on the Joint Property in a field operating capacity.
“Technical Employees” shall mean those employees having special and specific
engineering, geological or other professional skills, and whose primary function
in Joint Operations is the handling of specific operating conditions and
problems for the benefit of the Joint Property.
“Personal Expenses” shall mean travel and other reasonable reimbursable expenses
of Operator’s employees.
“Material” shall mean personal property, equipment or supplies acquired or held
for use on the Joint Property.
“Controllable Material” shall mean Material which at the time is so classified
in the Material Classification Manual as most recently recommended by the
Council of Petroleum Accountants Societies.
2. Statement and Billings
Operator shall bill Non-Operators on or before the last day of each month for
their proportionate share of the Joint Account for the preceding month. Such
bills will be accompanied by statements which identify the authority for
expenditure, lease or facility, and all charges and credits summarized by
appropriate classifications of investment and expense except that items of
Controllable Material and unusual charges and credits shall be separately
identified and fully described in detail.
3. Advances and Payments by Non-Operators

  A.   Unless otherwise provided for in the agreement, the Operator may require
the Non-Operators to advance their share of estimated cash outlay for the
succeeding month’s operation within fifteen (15) days after receipt of the
billing or by the first day of the month for which the advance is required,
whichever is later. Operator shall adjust each monthly billing to reflect
advances received from the Non-Operators.     B.   Each Non-Operator shall pay
its proportion of all bills within fifteen (15) days after receipt. If payment
is not made within such time, the unpaid balance shall bear interest monthly at
the prime rate in effect at
                                                             on the first day of
the month in which delinquency occurs plus 1% or the maximum contract rate
permitted by the applicable usury laws in the state in which the Joint Property
is located, whichever is the lesser, plus attorney’s fees, court costs, and
other costs in connection with the collection of unpaid amounts.

4. Adjustments
Payment of any such bills shall not prejudice the right of any Non-Operator to
protest or question the correctness thereof; provided, however, all bills and
statements rendered to Non-Operators by Operator during any calendar year shall
conclusively be presumed to be true and correct after twenty-four (24) months
following the end of any such calendar year, unless within the said twenty-four
(24) month period a Non-Operator takes written exception thereto and makes claim
on Operator for adjustment. No adjustment favorable to Operator shall be made
unless it is made within the same prescribed period. The provisions of this
paragraph shall not prevent adjustments resulting from a physical inventory of
Controllable Material as provided for in Section V.
