exchange information with respect to revenues received from production and other

expense belongs in the period before or after the Effective Time, or is properly

matters, then such item or matter may be submitted for determination to a
mutually acceptable accounting firm in accordance with Section 13.2 hereof.

point. Seller shall receive a credit in the final adjustment of the Purchase
Price as provided for in paragraph (a) above equal to an amount calculated by
multiplying the volume of such Hydrocarbons by (i) in the case of oil, the
posted price in the field, as of the Effective Time (or if none, a mutually
agreeable price) or (ii) in the case of gas, the prevailing spot market price
net of transportation and basis differential, as of the Effective Time

agreements described in (i) through (iii), of this paragraph (l) is in breach of
or default thereunder. No event, condition or occurrence exists which after

                    performance of this Agreement by Seller and the consummation
                    by it of the transactions contemplated hereby does not

                    which will not have been obtained on or prior to Closing;
                    does not, with or without the giving of notice or the

                    of trust, indenture or other agreement or instrument, or any
                    order, judgment, decree or any other restriction of any kind

                    by which they or any of their assets may be bound.

               (iv) Seller and Buyer agree that, except as otherwise expressly
                    provided in this Agreement, the Ownership Interest is being
                    purchased "AS IS," "WHERE IS" and "WITH ALL FAULTS," latent
                    and patent. WITHOUT LIMITING THE GENERALITY OF THE
                    FOREGOING, EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT,
                    SELLER HAS NOT MADE AND WILL NOT MAKE, AND HEREBY EXPRESSLY
                    DISCLAIMS, ANY WARRANTIES WHATSOEVER, EXPRESS OR IMPLIED,
                    WITH RESPECT TO OR RELATING TO THE OWNERSHIP INTEREST AND
                    UNDERLYING ASSETS OR ANY PORTION THEREOF, INCLUDING WITHOUT

                    Seller.

                    Except as otherwise expressly provided herein, Seller makes

                    condition or liability arising before or after this
                    Agreement pursuant to, or arising under, any federal, state
                    or local law, rule or ordinance, including

                                       11
<PAGE>

                    those relating to protection of the environment such as,
                    without limitation, the Clean Water Act, the Resource
                    Conservation and Recovery Act and/or the Comprehensive
                    Environmental Response, Compensation, and Liability Act.

          (o)  Seller is aware of no liabilities of LGG other than those
included on the balance sheet provided by Seller to Buyer. Seller is aware of no
other Material Contracts other than those included on EXHIBIT E hereto.

                             BUYER'S REPRESENTATIONS

     5.1  BUYER'S REPRESENTATIONS. Buyer represents to Seller as of the date
hereof that:

          (a)  It is a corporation, duly organized, validly existing and in good
standing under the laws of the State of Colorado, and Buyer is or prior to
Closing will be duly qualified pursuant to any and all applicable laws, statutes
and regulations to own and operate the Assets;

          (b)  It has all requisite power and authority to carry on its business
as presently conducted, to enter into this Agreement and the other documents and
agreements contemplated hereby, to purchase the Assets on the terms described in
this Agreement, and to perform its other obligations under this Agreement and
the other documents and agreements contemplated hereby. Subject to Section 15.1,
the consummation of the transactions contemplated by this Agreement will not
violate., nor be in conflict with, any provision of Buyer's charter, or
governing documents, or any material agreement or instrument to which Buyer is a
party or by which it is bound, or any judgment, decree, order, statute, rule or
regulation applicable to Buyer;

          (c)  The execution, delivery and performance of this Agreement and the
transactions contemplated hereunder have been duly and validly authorized by all
requisite action on the part of Buyer;

          (d)  This Agreement constitutes, and all documents and instruments
required hereunder to be executed and delivered by Buyer at Closing will
constitute, legal, valid and binding obligations of Buyer in accordance with
their respective terms, subject to bankruptcy and other similar laws of general
application with respect to creditors;

          (e)  There are no bankruptcy, reorganization or arrangement
proceedings pending, being contemplated by, or to the actual knowledge of the
officers of Buyer, threatened against Buyer;

          (f)  No broker or finder has acted for or on behalf of Buyer in
connection with this Agreement or the transactions contemplated by this
Agreement, and no broker or finder is entitled to any brokerage or finder's fee
or commission in respect thereof based in any way on agreements, arrangements or
understandings made by or on behalf of Buyer;

                                       12
<PAGE>

          (g)  Buyer is now or prior to Closing will be, and after Closing shall
continue to be, qualified to own Federal and State oil, gas and mineral leases
in all jurisdictions where any such Subject Interests are located, and the
consummation of the transactions contemplated hereby will not cause Buyer to be
disqualified as such an owner or to exceed any acreage limitation imposed by any
law, statute, rule or regulation;

          (h)  Buyer has arranged to have available by the Closing Date
sufficient funds to enable the Buyer to pay in full the Purchase Price, together
with all costs and expenses relative thereto, and otherwise to perform its
obligations under this Agreement.

          (i)  Buyer is purchasing the Ownership Interest for its own account
and sole interest, and is purchasing the Ownership Interest for investment and
not with a view to, or in connection with, any offering, resale, disposition or
distribution of any of the Ownership Interest.

          (j)  Buyer understands and acknowledges that no registration statement
relating to the Ownership Interest has been filed under the Securities Act of
1933, as amended (the "Act") and that consequently the Ownership Interest will
constitute "restricted securities" within the meaning of Rule 144 under the Act
and accordingly must be held by Buyer indefinitely and may not be sold or
otherwise disposed of in the absence of registration or an exemption from
registration under the Act and under applicable state securities laws. Buyer
realizes that there is no existing public market for the Ownership Interest and
that even if such market did exist, reliance upon Rule 144 under the Act for
public sales in limited amounts could occur only if adequate public information
about LL was available and only after Buyer has held the Ownership Interest
continuously for a period of at least two years from and after the date on which
the full purchase price for the Ownership Interest is paid. Buyer understands
and acknowledges that the Seller is under no obligation to register the
Ownership Interest under the Act or to aid Buyer in obtaining any exemption from
registration under the Act.

          (k)  The following is made as of the Closing Date only: Buyer has had
the opportunity to examine all information regarding LGG provided by Seller, and
Buyer has had the opportunity to ask questions of directors and officers of
Seller. The investment decision of Buyer to acquire the Ownership Interest has
been based solely upon Seller's representations with respect to the LGG and the
evaluation made by Buyer.

          (l)  Seller is not a Public Utility Holding Company as defined in the
Public Utility Holding Company Act of 1935, and, to the knowledge of Seller, it
is not a partner with any party who is a Public Utility Holding Company.

VI

                      ACCESS TO INFORMATION AND INSPECTION

     6.1  FILES. Seller has permitted Buyer and its representatives access to
all accounting records, abstracts of title, title opinions, title files,
ownership maps, lease files, assignments, division orders, check vouchers,
payout statements and agreements pertaining to the Assets insofar as the same
are now in existence and in the possession of Seller. Buyer and Seller
acknowledge that Buyer has had access to such records and information, prior to
the execution of this Agreement.

     6.2  OTHER FILES. Seller has made available to Buyer for inspection by
Buyer all geological, geophysical, production and engineering books, records and
data in possession of Seller, except such records or data which Seller is
prevented by contractual obligations with third parties from disclosing.

     6.3  CONFIDENTIALITY AGREEMENT. Buyer and Seller entered into that certain
Confidentiality Agreement dated June 23, 2000, between Seller and Buyer, the
terms of which are incorporated herein by reference and made a part of this
Agreement. The Confidentiality Agreement shall expire at Closing.

     6.4  INSPECTIONS. Seller has permitted Buyer and its representatives at
reasonable times and at their sole risk, cost and expense, to conduct reasonable
inspections of the Assets; provided, however, Buyer shall repair any damage to
the Assets resulting from such inspections and Buyer does hereby indemnify and
hold harmless Seller from and against any and all losses, costs, damages,
obligations, claims, liabilities, expenses or causes of action arising from
Buyer's inspection of the Assets, including, without limitation, claims for
personal injuries, property damage and reasonable attorney's fees and further
including claims arising in whole or part from Seller's negligence.


                                   ARTICLE VII
                                      TITLE

     7.1  NO WARRANTY OR REPRESENTATION. Seller shall convey Seller's interests
in and to the Real Property Assets to Buyer subject to the Permitted
Encumbrances and without any warranty of title, express or implied, except as to
claims by, through and under Seller, but not otherwise, as provided in the form
of Assignment, Bill of Sale and Conveyance attached as Exhibit C hereto. Seller
makes no warranty or representation, express or implied, with respect to the
accuracy or completeness of the information, records and data now, heretofore or
hereafter made available to Buyer in connection with this Agreement (including,
without limitation, any description of the Real Property Assets, pricing
assumptions, potential for production of Hydrocarbons from the Subject
Interests, prospects for LGG, or any other matters contained in any other
material furnished to Buyer by Seller or by Seller's agents or representatives).

     7.2  BUYER'S TITLE REVIEW.

          (a)  For 45 calendar days after Closing, Buyer may at Buyer's sole
cost and expense commence and diligently pursue such examination of title to the
Subject Interests as Buyer

                                       14
<PAGE>

desires. Seller shall fully cooperate with Buyer and shall make available to
Buyer at Seller's offices in Overland Park, Kansas, all documents, records and
material in Seller's possession (except to the extent disclosure of same is
prohibited pursuant to agreements with third parties) and all assistance
reasonably necessary to assist Buyer in determining the validity of Seller's
title in and to the Subject Interests. In no event, however, does Seller warrant
or represent the sufficiency, completeness or accuracy of such documents,
records and materials, and Buyer's reliance thereon shall be at Buyer's sole
risk and expense. In the event more than one property is being conveyed
hereunder, Buyer will review title on a property by property basis commencing
with the property being deemed to have the greatest value and then in descending
order of value as set forth on EXHIBIT B. Immediately upon completion of Buyer's
title review of each property, Buyer shall notify Seller of any Title Defects
associated with such property in accordance with Section 7.3 below. Buyer will
conclude Buyer's title review and give notice to Seller of all asserted Title
Defects not later than five (5) days after the end of said 45 day period. To be
effective, Buyer's written notice of a Title Defect must include (i) a brief
description of the matter constituting the asserted Title Defect and (ii)
supporting documents reasonably necessary for Seller (or a title attorney or
examiner hired by Seller) to verify the existence of such asserted Title Defect.
Any matters not described in a written notice of Title Defect as provided above
shall conclusively be deemed to have been waived and accepted by Buyer, and
shall be deemed Permitted Encumbrances hereunder.

          (b)  Upon receipt of the notice set forth under Section 7.2(a) Seller
shall have the right, but not the obligation, for 10 calendar days to cure all
or any portion of asserted Title Defects, such curative costs to be borne solely
by Seller. If Buyer elects to waive or is deemed to have waived any asserted or
unasserted Title Defects, such waived or unasserted Title Defects shall be
deemed Permitted Encumbrances hereunder. If Seller within the time provided
above is unable, elects not, or refuses, to cure such asserted Title Defects,
Buyer may, subject to Section 7.4 below, by written notice delivered to Seller
not later than two (2) business days after the end of such period, and as
Buyer's sole and exclusive remedy and only if the thresholds of Section 12.9
have been met, elect to have Seller refund to Buyer, a portion of the Purchase
Price by an amount attributable to the reserves to which title has failed as
mutually agreed upon by the parties and based upon the allocations made pursuant
to Section 3.3, and Buyer shall reconvey such portion of the Subject Interests
to Seller. Failure by Buyer to timely assert a claim for an adjustment to the
Purchase Price shall be deemed an election by Buyer to waive such claim and
retain the interest covered by the asserted but uncured Title Defect. In the
event Buyer and Seller are unable to agree upon the amount of the downward
adjustment of the Purchase Price attributable to a Title Defect for the purposes
of the foregoing, then the same shall be submitted for determination to a
mutually acceptable reservoir engineering firm whose determination shall be
final.

          (c)  Matters set out in EXHIBIT I shall not constitute a Title Defect;
provided, however, any mortgages listed in Exhibit I, if not released at
Closing, shall constitute a Title Defect.

     7.3  TITLE DEFECTS. For the purposes of this Agreement, a portion of the
Subject Interests shall be deemed to have a "Title Defect" if any one or more of
the following statements is untrue in any material respect with respect to such
portion of the Subject Interests as of the Effective Time:

          (i)  Seller has Defensible Title thereto.

                                       15
<PAGE>

          (ii)  All royalties, rentals, Pugh clause payments, shut-in gas
payments and other payments due with respect to such portion of the Subject
Interests have been properly and timely paid, except for payments held in
suspense for title or other reasons which are customary in the industry and
which will not result in grounds for cancellation of Seller's rights in such
portion of the Subject Interests.

          (iii) Except as set forth in any of the Exhibits hereto, Seller is not
in default under the material terms of any leases, farmout agreements or other
contracts or agreements respecting such portion of the Subject Interests which
could (1) materially interfere with the operation; value or use thereof, (2)
materially prevent Seller from receiving the proceeds of production attributable
to Seller's interest therein, or (3) result in cancellation of Seller's interest
therein.

          (iv)  There is no lien, charge, encumbrance, defect or objection
(other than a Permitted Encumbrance) against, in or to Seller's title thereto or
right or interest therein, and no fact or circumstance relative thereto exists
of such significance that a reasonable and prudent person engaged in the
business of the ownership, development and operation of oil and gas properties
with knowledge of all the facts and appreciation of their legal significance
would be unwilling to accept and pay for the Subject Interest or portion thereof
which is affected thereby.

     Notwithstanding the foregoing, loss of any Subject Interest or portion
thereof following the Effective Time due to (i) any election or decision made by
Seller in accordance with Article IX or (ii) expiration of the primary or
secondary term of a lease shall not constitute a Title Defect as long as Seller
shall not have breached the provisions of Article IX. Subject to Section 15.1
below, the failure of any governmental office to approve or consent to any
assignment or other conveyance of a Subject Interest filed with such office
shall not constitute a Title Defect; provided that such office has not expressly
and specifically refused to grant such consent or approval as a result of the
existence of a Title Defect.

     7.4  TITLE INDEMNIFICATION. Notwithstanding any other provisions of this
Article VII, Seller shall have the option to execute and deliver to Buyer a
title indemnity whereby Seller shall keep Buyer indemnified from and against any
and all liability, loss, costs (including legal costs), suits, judgments, causes
of action, claims or damages arising or incurred in connection with any uncured
Title Defects, to the extent the same relate to acts, omissions or other matters
occurring prior to the Effective Time and only with respect to such uncured
Title Defects. The title indemnity shall be limited to the amount determined in
accordance with this Article VII with respect to the particular Asset for which
the indemnity is given. If Seller provides such a title indemnity, the relevant
uncured Title Defects shall be deemed to be cured and removed for the purposes
of this Agreement.


                                  ARTICLE VIII
                    PREFERENTIAL PURCHASE RIGHTS AND CONSENTS

     8.1  PREFERENTIAL RIGHT. A preferential purchase right exists with respect
to the Subject Interests and the Ownership Interest. Immediately upon signing of
this Agreement, a copy of this

                                       16
<PAGE>

Agreement along with the requisite notices under the preferential purchase
rights shall be sent to the parties entitled thereto.

     8.2  CONSENTS. A consent to the transfer of the Ownership Interest is
required. In the event the consent is not received before Closing, Seller shall,
at Closing, transfer the beneficial ownership of the Ownership Interest to Buyer
and shall designate, as Seller's representatives with respect to management of
LGG, persons designated by Buyer. Seller shall provide all notices to Buyer that
it receives and shall act as Buyer's agent with respect to LGG, but only based
on instructions from Buyer. Buyer shall indemnify Seller with respect to all any
and all claims made against Seller with respect to Seller's actions on Buyer's
behalf with respect to LGG.


                                   ARTICLE IX
                               COVENANTS OF SELLER

     9.1  COVENANTS OF SELLER PENDING CLOSING. From and after the date of
execution of this Agreement and until the Closing, except as otherwise consented
to by Buyer in writing and subject to Section 9.2 below and the terms of
applicable operating and other agreements, Seller shall:

          (a)  Subject to Seller's right to obtain Seller's Credits pursuant to
Section 3.2, continue to operate the Assets owned by it for the account of Buyer
in a manner consistent with past practices;

          (b)  Maintain in full force and effect all policies of insurance
covering the Assets now maintained by Seller;

          (c)  Use reasonable efforts to preserve in full force and effect all
material leases, operating agreements, easements, rights-of-way, permits,
licenses, contracts and other material agreements included in the Incidental
Rights which relate to the Assets in which it owns an interest and perform all
material obligations of Seller in or under any such agreement relating to such
Assets;

          (d)  Not enter into any agreement or arrangement granting any
preferential right to purchase any of the Assets or requiring the consent of any
person to the transfer and assignment of any of the Assets hereunder, except in
connection with the performance by Seller of an obligation or agreement existing
on the date hereof or pursuant to this Agreement;

          (e)  Not dedicate, sell, farm out, encumber or dispose of any Assets
without Buyer's written consent except (i) sales of oil and gas production in
the ordinary course of business and (ii) as to a portion of the Assets that do
not, in the aggregate, constitute a material portion of the Assets; and

          (f)  Maintain all material equipment included in the Assets in
accordance with customary industry operating practices and procedures.

                                       17
<PAGE>

     Notwithstanding the other provisions of this Article IX, (i) Seller may
take any action with respect to the Assets if reasonably necessary under
emergency circumstances and provided Buyer is notified as soon thereafter as
reasonably practical, (ii) except as to a reduction in the Purchase Price
attributable to a Title Defect, Seller shall have no liability to Buyer for the
incorrect payment of royalties, shut-in royalties or similar payments or for any
failure to pay any such payments through mistake or oversight (including
Seller's negligence), and (iii) Seller's non-willful failure to comply with any
of the requirements of this Article IX shall not be deemed a default by Seller
hereunder, serve as a basis for a claim by Buyer for damages (other than a
reduction of the Purchase Price as a result of the failure of title), afford
Buyer the right to make a claim for damages or permit Buyer not to close this
sale if such failure does not have a material adverse effect on the value of the
Assets taken as a whole. Any consent requested of Buyer with respect to the
matters covered by this Article IX shall not be unreasonably withheld or action
with respect thereto unduly delayed.

     9.2  LIMITATIONS ON SELLER'S COVENANTS PENDING CLOSING.

          (a)  To the extent Seller is not the operator of any of the Assets,
the obligations of Seller in Section 9.1 above, which have reference to
operations or activities which normally or pursuant to existing contracts are
carried out or performed by the operator, shall be construed to require only
that Seller use reasonable efforts (without being obligated to incur any expense
or institute any cause of action) to cause the operator of such Assets to take
such actions or render such performance within the constraints of the applicable
operating agreements and other applicable agreements.

          (b)  Notwithstanding anything to the contrary in this Article IX,
should Seller not wish to pay any lease rental or other payment or participate
in any reworking, deepening, drilling, completion, equipping or other operation
on or with respect to any well or other Asset which may otherwise be required by
Section 9.1 above, Seller shall give Buyer timely written or oral notice thereof
as soon as reasonably practicable after Seller receives written notice thereof
from the operator of such property (or if Seller is the operator, at the same
time Seller gives written notice thereof to the non-operators of such property);
and Seller shall not be obligated to make any such payment or to elect to
participate in any such operation which Seller does not wish to make or
participate in unless Seller receives from Buyer, within a reasonable time prior
to the date when such payment or election is required to be made by Seller, (i)
the written election and agreement of Buyer to require Seller to take such
action and to indemnify Seller therefrom and (ii) all funds necessary for such
action. Notwithstanding the foregoing, Seller shall not be obligated to pay any
lease rental or other payment or to elect to participate in any operation if the
third party operator of the property involved recommends that such action not be
taken. If Buyer advances any funds pursuant to this Section 9.2(b) and the
Assets to which such payments relate are not conveyed to Buyer at Closing, and
Seller does not reimburse Buyer for all advances made by Buyer with respect to
such Assets pursuant to this Section 9.2(b) within thirty (30) days after this
Agreement terminates with respect to such Assets, then (i) Buyer shall own and
be entitled to any right of Seller that would have lapsed but for such payment,
and (ii) in the case of operations, Buyer shall be entitled to receive the
penalty which Seller, as nonconsenting party, would have suffered under the
applicable operating agreement with respect to such operations as if Buyer were
a consenting party thereunder.

                                   ARTICLE XII
                                EFFECT OF CLOSING

     12.1 REVENUES. To the extent not included in the reimbursements under
Section 3.2 hereof, all proceeds, accounts receivable, notes receivable,
revenues, monies and other items included in or attributable to the Excluded
Assets and all other Excluded Assets shall belong to and be paid over to Seller
and all other proceeds, accounts receivable, notes receivable, revenues, monies
and other items relating to the period of time after the Effective Time and
included in or attributable to the Assets shall belong to and be paid over to
Buyer.

     12.2 TAXES.

          (a)  Apportionment of Ad Valorem and Property Taxes. All ad valorem,
real property taxes and personal property taxes, including interest and
penalties attributable thereto (hereinafter "Property Taxes"), attributable to
the Assets with respect to the tax assessment period ("Tax Period") during which
the Effective Time occurs shall be apportioned as of the Effective Time between
Seller and Buyer, with Seller paying a fraction thereof based upon the number of
days in the Tax Period prior to the Effective Time and Buyer paying the balance
thereof. This allocation prevails even if the assessment for the Tax Period is
attributable, in whole or in part, to a prior calendar year. The owner of record
on the assessment date shall file or cause to be filed all required reports and
returns incident to the Property Taxes and shall pay or cause to be paid to the
taxing authorities all Property Taxes relating to the Tax Period during which
the Effective Time occurs. If Seller is the owner of record on the assessment
date, then Buyer shall pay to Seller Buyer's pro rata portion of Property Taxes
within thirty (30) days after receipt of Seller's invoice therefor, except to
the extent taken into account as an adjustment to the Purchase Price pursuant to
Section 3.2. If Buyer is the owner of record as of the assessment date then
Seller shall pay to Buyer Seller's pro rata portion of Property Taxes within
thirty (30) days after receipt of Buyer's invoice therefor, except to the extent
taken into account as an adjustment to the Purchase Price pursuant to Section
3.2.

          (b)  Sales Taxes. The Purchase Price provided for hereunder excludes,
and Buyer shall be liable for, any Transfer Taxes (as defined below) required to
be paid in connection with the sale of the Assets pursuant to this Agreement. To
the extent required by applicable law, Seller shall collect and remit any
Transfer Taxes that are required to be paid as a result of the transfer of the
Assets by Seller to the Buyer. If the transfer of the Assets pursuant to this
Agreement is exempt from any Transfer Taxes, Buyer shall, at Closing, provide
Seller with properly executed exemption

                                       22
<PAGE>

certificates or other documentation acceptable under applicable law. As used
here, the term "Transfer Taxes" shall mean any sales, use, excise, stock, stamp,
document, filing, recording, registration, authorization and similar taxes, fees
and charges.

          (c)  Other Taxes. With the exception of income and franchise taxes,
all other federal, state and local taxes (including interest and penalties
attributable thereto) on the ownership or operations of the Assets which are
imposed with respect to periods or portions of periods prior to the Effective
Time shall be paid by Seller and all such taxes imposed with respect to periods
or portions of periods beginning on or after the Effective Time shall be paid by
Buyer.

          (d)  Cooperation. After the Closing, each party to this Agreement
shall provide the other party with reasonable access to all relevant documents,
data and other information (other than that which is subject to any
attorney-client privilege) which may be required by the other party for the
purpose of preparing tax returns, filing refund claims and responding to any
audit by any taxing jurisdiction. Each party to this Agreement shall cooperate
with all reasonable requests of the other party made in connection with
contesting the imposition of taxes. Notwithstanding anything to the contrary in
this Agreement, neither party to this Agreement shall be required at any time to
disclose to the other party any Tax Return or other confidential tax
information. Except where disclosure is required by applicable law or judicial
order, any information obtained by a party pursuant to this Section 12.2(d)
shall be kept confidential by such party, except to the extent disclosure is
required in connection with the filing of any Tax Returns or claims for refund
or in connection with the conduct of an audit, or other proceedings in response
to an audit, by a taxing jurisdiction.

     12.3 EXPENSES. To the extent not included in the reimbursements under
Section 3.2 hereof or in the Assumed Obligations, all accounts payable and other
costs and expenses (other than taxes described in Section 12.2) with respect to
the Seller's interest in the Assets which are attributable under GAAP to the
period prior to the Effective Time shall be the obligation of and be paid by
Seller, and those which are attributable under GAAP to the period commencing
with the Effective Time, as well as all Assumed Obligations, shall be the
obligation of and be paid by Buyer.

     12.4 SHARED OBLIGATIONS. If monies are received by any party hereto which,
under the terms of this Article XII, belong to another party, the same shall
immediately be paid over to the proper party. If an invoice or other evidence of
an obligation is received which under the terms of this Article XII is partially
the obligation of Seller and partially the obligation of Buyer, then the parties
shall consult each other and each shall promptly pay its portion of such
obligation to the obligee, provided that if either party hereto shall fail
promptly to pay its portion of such obligation to the obligee, the other party
hereto shall have the right (but not the obligation) to pay such portion of such
obligation, whereupon the defaulting party shall promptly reimburse such other
party for the defaulting party's portion so paid, plus interest on said amounts
until reimbursed, at the rate applicable under Article III above.

     12.5 SELLER OPERATED PROPERTIES. It is expressly understood and agreed that
Seller shall not be obligated to continue operating any of the Assets following
the Closing Date and Buyer hereby

                                       23
<PAGE>

assumes full responsibility for operating (or causing the operation of) all
Assets following the Closing Date.

     12.6 RESERVATION OF RIGHT TO QUALIFY UNDER SECTION 29 OF THE CODE. Seller
hereby retains, and Buyer consents thereto, the right to seek qualification of
certain of the Real Property Assets under Section 29 of the Internal Revenue
Code of 1986, as amended, and as gas produced from coal seams under Section 503
of the Natural Gas Policy Act of 1978 (and including any successor or similar
state or federal legislation) before the Federal Energy Regulatory Commission,
or its successor agency. This reservation is not intended to reserve any rights
to claim Section 29 credits with respect to production occurring after the
Effective Date, but rather is to assure Seller's right to such credits prior to
the Effective Date. Buyer agrees to cooperate fully with Seller at Seller's
expense and to permit access to Buyer's records and all reasonable time to
permit Seller to complete this qualification process.


                                  ARTICLE XIII
                            SETTLEMENT OF PRORATIONS

     13.1 ACCOUNTING. Prior to Closing, Seller shall furnish Buyer with an
estimated accounting showing in reasonable detail the prorating of any amounts
described in and subject to Article XII of this Agreement. If pursuant to such
estimated accounting either Seller or Buyer shall owe any obligation to the
other which is not included in the reimbursements under Section 3.2, then the
Purchase Price paid at Closing shall be further adjusted to reflect such charges
and credits which are necessary to accomplish such adjustment. Promptly after
the Closing Date (but not later than one hundred twenty (120) days thereafter),
Seller shall furnish Buyer with a final accounting showing in reasonable detail
the prorating of any amounts described in and subject to Article XII hereof.

     13.2 SETTLEMENT OF DISPUTES. If within thirty (30) days after Seller
furnishes such final accounting to Buyer, Buyer and Seller are unable to agree
on such final accounting or the adjustments provided for in Section 3.2 hereof,
then either Seller or Buyer may submit such proration or allocation dispute to a
mutually acceptable accounting firm, and the determination made as to such
proration or allocation by such accounting firm shall be final and binding upon
Seller and Buyer. Final settlement shall be made within ten (10) business days
following agreement by the Buyer and Seller or final determination by said
accounting firm. All determinations and adjustments with respect to allocating
items to the periods before or after the Effective Time shall be in accordance
with GAAP. The fees charged by said accounting firm for making determinations
under Section 3.2 or this Section 13.2 shall be paid one-half (1/2) by Buyer and
one-half (1/2) by Seller.


                                   ARTICLE XIV
                                  ENVIRONMENTAL

     14.1 AVAILABILITY OF DATA TO BUYER: The Assets which are the subject of
this Agreement have been utilized by Seller for the purposes of exploration,
development and production of oil and gas, for related oilfield operations and
possibly for the storage and disposal of waste materials or hazardous
substances. Seller shall make available to Buyer, during the environmental
assessment period described in Section 14.3 below, Seller's historical files
regarding the foregoing operations,

                                       24
<PAGE>

to the extent available and to the extent Seller is authorized to disclose same
(excepting documents subject to confidentiality restrictions or legal
privilege).

     14.2 SPILLS AND NORM: Without changing the allocation of risk reflected in
Section 13.7 and 13.8, and without creating knowledge on Buyer's part that could
or would limit or eliminate Seller's indemnification under Section 13.8(c)(ii).
Buyer acknowledges that in the past there may have been spills of wastes, crude
oil, produced water, or other materials (including, without limitation, any
toxic, hazardous or extremely hazardous substances) onto the Lands. In addition,
some production equipment may contain asbestos and/or Naturally Occurring
Radioactive Material (hereinafter referred to as "NORM"). In this regard Buyer
expressly understands that NORM may affix or attach itself to the inside of
wells, materials and equipment as scale or in other forms, that said wells,
materials and equipment located on the Lands or included in the Assets described
herein may contain NORM and that NORM-containing material may have been buried
or otherwise disposed of on the Lands. Buyer also expressly understands that
special procedures may be required for the remediation, removal, transportation
and disposal of asbestos, NORM or other materials from the Assets and Lands
where such material may be found and that Buyer assumes all liability for or in
connection with the assessment, containment, removal, remediation,
transportation and disposal of any such materials, in accordance with all past,
present or future applicable laws, rules, regulations and other requirements of
any governmental or judicial entities having jurisdiction and also with the
terms and conditions of all applicable leases and other contracts.

     14.3 BUYER AGREES TO RELEASE, INDEMNIFY, DEFEND AND HOLD SELLER HARMLESS
FROM ANY CLAIM, CAUSE OF ACTION, JUDGMENT, LIABILITY, LOSS, DAMAGE OR OTHER COST
WHATSOEVER BROUGHT BY OR IN FAVOR OF ANY PERSON FOR INJURY, ILLNESS OR DEATH,
DAMAGE TO OR LOSS OF PROPERTY, FOR DAMAGE OR HARM TO THE ENVIRONMENT OR FOR ANY
OTHER MATTER CAUSED BY BUYER'S ACCESS TO THE LANDS OR THE ENVIRONMENTAL
ASSESSMENT OR TESTING THEREOF, EVEN IF SUCH LIABILITY IS ATTRIBUTABLE TO THE
CONTRIBUTORY NEGLIGENCE OF SELLER; PROVIDED, THE FOREGOING SHALL NOT APPLY TO
ANY CLAIM, CAUSE OF ACTION, JUDGMENT, LIABILITY, LOSS, DAMAGE OR OTHER COST
WHATSOEVER TO THE EXTENT ARISING FROM CONDITIONS ON THE LANDS AS OPPOSED TO
BUYER'S ACTIVITIES ON THE LAND PRIOR TO CLOSING.

     14.4 MATERIAL ADVERSE ENVIRONMENTAL CONDITIONS: Buyer's sole and exclusive
remedy for environmental conditions is as provided in Section 14.8.

     14.5 "AS IS, WHERE IS" PURCHASE: Subject to Section 14.8, Buyer shall
acquire the Assets in an "AS IS, WHERE IS" condition and shall assume all risks
that the Assets may contain waste materials (whether toxic, hazardous, extremely
hazardous or otherwise) or other adverse physical conditions, including, but not
limited to, the presence of unknown abandoned oil and gas wells, water wells,
sumps, pits, pipelines or other waste or spill sites which may not have been
revealed by Buyer's investigation. On and after the Effective Time, all
responsibility and liability related to all such conditions, whether known or
unknown, fixed or contingent, will be transferred from Seller to Buyer, except
as provided in Section 14.8.

                                       25

handle, remove, transport and dispose of any material, substance or waste
(whether toxic, hazardous, extremely hazardous or otherwise) from the Assets or
Lands (including, but not limited to, produced water, drilling fluids and other
associated wastes), whether present before or after the Effective Time, in
accordance with applicable local, state and federal laws and regulations. To the
extent that the Lands are not sold in fee to Buyer, Buyer shall keep records of
the types, amounts and location of materials, substances and wastes which are
transported, handled, discharged, released or disposed onsite and offsite. When
and if any lease, an interest in which has been assigned pursuant to this
Agreement, is terminated, Buyer shall take whatever additional testing,
assessment, closure, reporting or remedial action with respect to the Assets or
Lands as is necessary to meet any local, state or federal requirements directed
at protecting human health or the environment in effect at that time, and any
other action as necessary to restore the Lands or Assets to their original
condition.

AND PERSONAL PROPERTY SHALL BE CONVEYED TO BUYER AS IS AND IN THEIR PRESENT
CONDITION AND STATE OF REPAIR, AND BUYER REPRESENTS TO SELLER THAT BUYER HAS

THE REAL PROPERTY, IMMOVABLE PROPERTY, MOVABLE PROPERTY, EQUIPMENT, INVENTORY,
MACHINERY, FIXTURES AND PERSONAL PROPERTY AS IS, IN THEIR PRESENT CONDITION AND
STATE OF REPAIR, IT BEING THE EXPRESS INTENTION OF BOTH BUYER AND SELLER THAT
THE PERSONAL PROPERTY, EQUIPMENT AND FIXTURES INCLUDED WITHIN THE ASSETS ARE
HEREBY CONVEYED TO BUYER IN THEIR PRESENT CONDITION AND STATE OF REPAIR, "AS IS"
AND "WHERE IS" WITH ALL FAULTS, AND THAT BUYER HAS MADE OR CAUSED TO BE MADE

EXTENT REQUIRED BY APPLICABLE LAW TO BE EFFECTIVE, THE DISCLAIMERS OF CERTAIN
WARRANTIES CONTAINED IN THIS SECTION ARE "CONSPICUOUS" DISCLAIMERS FOR THE
PURPOSES OF ANY APPLICABLE LAW, RULE OR ORDER. To the maximum extent permitted
by law, Buyer waives all provisions of the Texas Deceptive Trade Practices Act,
Chapter 17, Texas Business and Commerce Code (other than Section 17.555 thereof)
and, to the extent permitted by law, similar such provisions in like Acts in all
other applicable jurisdictions, insofar as the provisions of such act may be
applicable to this Agreement or the transactions contemplated hereby. To
evidence its ability to grant such waiver, Buyer hereby represents and warrants
to Seller that the Buyer (i) is seeking or acquiring, by purchase or lease,
goods or services for commercial or business use, (ii) has assets of $5 million
or more according to its most recent financial statement prepared in accordance
with GAAP, (iii) has knowledge and experience in financial and business matters
that enable it to evaluate the merits and risks of the transaction contemplated

qualified to take, tax credits under Section 29 of the Internal Revenue Code
with respect to production from the Subject Interests.

     15.7 SURVIVAL. No representation, warranty, covenant or agreement made
herein shall survive the Closing except as provided in this Section 15.7. It is
expressly agreed that the terms and provisions of Articles I, III, IV, V, VIII,
XII, XIII, and XV and Sections 6.3, 6.4, 7.1, Sections 14.1 through 14.7 and
Section 14.9, shall survive the Closing. The terms and provisions of Section
14.8 shall expire according to its terms.

     15.8 GAS IMBALANCE: Buyer acknowledges and agrees to the following
regarding gas imbalances as of the Effective Time on any of the Assets to be
transferred pursuant to this Agreement:

          (a)  GAS UNDERPRODUCTION: In the event Seller is underproduced as to
any wells located on the Lands or if any amounts are owed Seller with respect to
any pipeline, transportation or processing imbalances, Buyer agrees not to hold
Seller liable for such underproduction or such amounts. Seller, however, agrees
to assign to Buyer all of its contractual rights to make up such
underproduction, and to recover all amounts owed.

          (b)  GAS OVERPRODUCTION: In the event Seller is overproduced as to any
wells located on the Lands or if any amounts are due from Seller with respect to
any pipeline, transportation or processing imbalances, Buyer acknowledges and
agrees that its share of gas from any such overproduced wells may at some point
be curtailed by underproduced working interest

                                       32
<PAGE>


owners and it may be required to satisfy, in kind or in value, such third party
transporters and processors for such imbalances. Seller shall not be liable to
Buyer in the event such curtailment occurs or satisfaction is required.

          (c)  GAS BALANCING STATEMENTS: Seller has furnished Buyer with
statements in its possession showing the most current status of the before
mentioned imbalances and these statements are summarized in EXHIBIT M.

          (d)  FUTURE LIABILITY: From and after the Effective Time, any and all
benefits, liabilities associated with such imbalance accounts shall accrue to
and be the responsibility of Buyer. Buyer shall assume Seller's overproduced or
underproduced position in the Assets as of the Effective Time, including but not
limited to Buyer's responsibility for payment of royalties on the volume of such
gas which Seller took in excess of its entitlement and any obligation to balance
whether in cash or in kind. Except as provided in Section 17.9(e), there shall
be no adjustment to the Purchase Price as a result of the imbalance accounts
attributable to the Assets.

          (e)  ADJUSTMENT TO PURCHASE PRICE: In the event either Seller or Buyer
determines no later than sixty (60) days after the Closing Date that a
"material" error was made with the imbalance account set forth in EXHIBIT M or
that a material change (either increase or decrease) exists between the
imbalance represented in EXHIBIT M and the imbalance as of the Effective Time in
such an account, the adjustments under Section 3.2, shall be adjusted to
compensate for the economic impact of the error or change. Such an error or
change is material only if the total difference in the value of the imbalance
accounts as set forth in EXHIBIT M and the correct or changed imbalance accounts
exceeds ten percent (10%) of the value of the imbalance accounts as set forth in
Exhibit M, but in no event less than $100,000.00. For the purposes of this
Section only, the value of such an imbalance account adjustment shall be
calculated by multiplying the applicable volume of gas by $2.50 per MMBtu which
shall represent the value of such imbalance and then making appropriate
adjustments for royalties and severance taxes and similar taxes, if any,
actually paid on such amount or which will be required to be paid. The Purchase
Price shall be reduced or increased by the adjustments for such gas imbalance
changes on the Effective Time for material errors discovered prior to the
Effective Time. Adjustments for material errors discovered after the Closing
Date shall be included in a final settlement statement as provided herein.

                              LITIGATION AND CLAIMS

     Evergreen Resources, Inc. v. MGP Enterprises, Meggison and Chandler &
Associates, LLP, Case No 99-CV-104, Las Animas County District Court, Colorado.

     MGP Enterprises ("MGP") leased certain properties (called the "Lorencito
     Tract") adjacent to Apache Canyon properties to Evergreen Resources, Inc.
     ("Evergreen") After the lease expired due to lack of drilling, MGP
     Enterprises leased the Lorencito Tract to Chandler & Associates, LLP
     ("Chandler"), on condition that Chandler enter into an indemnification
     agreement with MGP and its principal, Meggison. Chandler entered into the
     lease and an indemnification letter agreement, dated June 28, 1999. The
     letter agreement provides, in part, that Chandler is responsible for the
     full defense costs (including attorneys' fees) to defend MGP, Meggison,
     MGP's partners, counsel and affiliates in any suit brought by Evergreen
     respecting the Lorencito Tract, and to indemnify those parties against any
     judgments rendered, except to the extent of fraud, intentional misconduct
     or other similar tort or contractual claim. Pursuant to an AMI agreement
     between Apache Canyon Gas, L.L.C. ("Apache Canyon") and Chandler, Chandler
     offered a 50% assignment of the lease, and the associated indemnification
     agreement, to Apache Canyon. Apache Canyon agreed to the assignment of a
     50% interest in the lease and assumption of 50% of the indemnification
     obligations under the indemnification agreement.

     Evergreen Resources subsequently filed suit against MGP, Meggison and
Chandler, alleging that MGP had agreed to extend the lease, and that MGP
breached a lease covenant requiring MGP to provide Evergreen a right of first
offer on the lease granted to Chandler.

     Plaintiff amended the complaint to add new defendants, including Apache
Canyon Gas, L.L.C. and KLT Gas Inc. The amended complaint seeks, among other
things, monetary damages from certain of the named defendants (not including
Apache Canyon Gas, L.L.C. or KLT Gas Inc.) and a declaration that plaintiff has
a valid oil and gas lease to a certain tract of land in Las Animas County,
Colorado. KLT Gas Inc. has no direct interest in the tract.
