position inconsistent therewith upon examination of any Tax Return, in
any refund claim, in any litigation, investigation, or otherwise.

(b) Buyer and Seller acknowledge and agree that the Purchase
Price includes and is inclusive of any and all sales, use, transfer or
other similar Taxes imposed as a result of the consummation of the

9.2 REASONABLENESS OF COVENANT. Seller acknowledges that the
covenant provided in Section 9.1 hereof is manifestly reasonable on its face and
is no more restrictive than is required for the protection of Buyer in its
acquisition and operation of the Transferred Assets in that such covenant is
given in consideration for Buyer's performance of its obligations under this
Agreement and the other agreements called for herein. In the event the
provisions of Section 9.1 should ever be deemed to exceed the time and
geographic limitations permitted by applicable law, then such provisions shall
be reformed to the maximum time or geographic limitations permitted by
applicable law.

9.3 INJUNCTIVE RELIEF. It is specifically understood and agreed
that any breach or threatened breach of the provisions of Section 9.1 hereof is
likely to result in irreparable harm to Buyer and that an action at law for
damages alone will be an inadequate remedy for such breach or threatened breach,
and that Buyer would suffer irreparable harm in the event Seller fails to comply
with its obligations hereunder. Therefore, in addition to any other remedy that
may be available to it, Buyer shall be entitled to enforce the specific
performance of Section 9.1 by Seller and to seek both temporary and permanent
injunctive relief (to the extent permitted by law) without the necessity of
proving actual damages, and such other relief as the court may allow. The
provisions of Article XV shall not be applicable to this Article IX or to the
enforcement of its provisions.

ARTICLE X
ADDITIONAL AGREEMENTS

10.1 DELIVERY OF CORPORATE DOCUMENTS. Seller shall deliver to Buyer
a copy of all Records, including computer disks reflecting any books or records,
documents or other papers, or other information or data relating to the
ownership or operation of the Transferred Assets stored on any electronic media,
including computers. Seller agrees that, Buyer and its authorized
representatives, upon the execution of Seller's standard confidentiality
agreement, shall have the right to inspect and, at Buyer's expense, copy, at any
time during regular business hours for any proper purpose, the corporate,
accounting, auditing and tax books, records (including work papers) and other
books and records relating to the ownership and operation of the Transferred
Assets as are retained by Seller or its Affiliates.

10.2 FURTHER ASSURANCES. Seller shall execute, acknowledge and
deliver or cause to be executed, acknowledged and delivered to Buyer at Closing
the Conveyance Documents and other instruments of transfer, assignment and
conveyance, in form and substance satisfactory to counsel for Buyer, as shall be
necessary or desirable to vest in Buyer all the right, title and interest in and
to the Transferred Assets free and clear of all Liens (including the release of
all Liens of record) and shall use commercially reasonable efforts to cause to
be taken the other action as Buyer reasonably may require to more effectively
implement and carry into effect the transactions contemplated by this Agreement.

10.3 COOPERATION AFTER CLOSING.

(a) Seller and Buyer shall cooperate with each other during
the period ending twenty (20) years after the Closing in clearing the
title to any of the Transferred Assets to Buyer pursuant hereto if
Seller's title to any such property

-24-
29

as of the Closing Date, shall be defective, not marketable or
nonassignable. In this connection, Seller shall take all commercially
reasonable action, including the furnishing of documents and evidences
of title and assistance in the preparation and trial of any necessary
litigation, to clear title to any the property, all of which shall be
at the expense of Seller.

(b) For the greater of five years from the Closing Date and
the period as may be required by any statute, regulation or
Governmental Authority or any then pending litigation, Buyer shall
permit Seller and its representatives reasonable access to the Records
that are transferred to Buyer in connection herewith in anticipation
of, or preparation for, existing or future litigation or any Tax audit
which Seller or any of its Affiliates is involved and which is related
to the Business or the Transferred Assets, during regular business
hours and upon reasonable notice at Buyer's principal places of
business or at any location where the Records are stored; provided that
(i) any access shall be had or done in a manner so as to not interfere
with the normal conduct of the Business, (ii) Buyer shall not be
required to provide access to any confidential record or records, the
disclosure of which would violate any statute or regulation or
applicable confidentiality agreement with any Person, and (iii) Buyer
shall not be required to provide access to any confidential record or
records, the disclosure of which would cause Buyer or any of its
Affiliates to waive its attorney-client privilege or attorney work
product privilege.

(c) For the greater of five years from the Closing Date and
the period as may be required by any statute, regulation or
Governmental Authority or any then pending litigation, Seller shall
permit Buyer and its representatives reasonable access to the general
business records and files of Seller in anticipation of, or preparation
for, existing or future litigation or any Tax audit in which Buyer or
any of its affiliates is involved and which is related to the Business
or the Transferred Assets, during regular business hours and upon
reasonable notice at Seller's principal places of business or at any
location where the records or files are stored; provided that (i) any
access shall be had or done in a manner so as to not interfere with the
normal conduct of Seller's business, (ii) Seller shall not be required
to provide access to any confidential record or records, the disclosure
of which would violate any statute or regulation or applicable
confidentiality agreement with any Person, and (iii) Seller shall not
be required to provide access to any confidential records or files, the
disclosure of which would cause Seller or any of its Affiliates to
waive its attorney-client privilege or attorney work product privilege.

10.4 CONTINUATION OF OPERATIONS; RIGHT OF FIRST REFUSAL.

(a) Nothing in this Agreement, in any Exhibit or Schedule
hereto, or in any agreement, instrument or other document executed or
delivered in connection with this Agreement shall require Buyer to
continue its business or operations or to manage and operate the
Transferred Assets. Seller acknowledges and agrees that Buyer, in its
sole discretion, may continue, manage, modify or discontinue its
operations, liquidate or otherwise change or cease its operations.

-25-
30

(b) Notwithstanding the foregoing, should Buyer elect to
discontinue, liquidate, materially change or cease operation of the
Transferred Assets, it will give Seller at least ninety (90) days prior
written notice thereof, and Seller shall have a period of thirty (30)
days after receipt of Buyer's notice to deliver a written notice to
Buyer that it elects to acquire the Transferred Assets. If Seller
elects to acquire the Transferred Assets, Buyer shall, upon receipt of
payment from Seller of the fair market value (as defined below) of the
Transferred Assets, convey the same to Seller free and clear of all
Liens and Claims created by, through or under Buyer. For purposes of
this Section 10.4, "fair market value" shall be the fair market value
of the Transferred Assets as of the date of the notice from Buyer and
as determined by an independent appraiser acceptable to both parties,
such acceptance not to be unreasonably withheld. Such independent
appraiser shall be someone with at least ten years experience in the
gas processing industry.

(c) Should Buyer wish to sell or otherwise transfer the
Transferred Assets or to sell or otherwise transfer such assets
together with the Frac Agreement, the O&M Agreement, the Lease
Agreement and/or the Sublease Agreement (collectively the "Project
Agreements") either directly or indirectly through a merger,
consolidation, amalgamation or otherwise, or should Buyer receive an
offer, to purchase any of the Transferred Assets and/or the Project
Agreements, whether directly or indirectly through a merger,
consolidation, amalgamation or otherwise, which offer Buyer wishes to
accept, Buyer shall furnish to Seller in writing the material
provisions of such proposed sale, transfer or purchase (the "Offer
Notice"). Seller shall have thirty (30) days after receipt of the Offer
Notice to give written notice of its election to acquire such assets
and/or agreements described in the Offer Notice for the consideration
and subject to the terms and conditions set forth in the Offer Notice.
If Seller fails to respond within such thirty (30) day period or elects
not to acquire such assets and/or agreements, Buyer shall be free for a
period of six (6) months from the end of such thirty (30) day period to
transfer the Transferred Assets and/or the Project Agreements, as may
be the case, for consideration and under terms and conditions no less
favorable to Buyer than those set forth in the Offer Notice.

(d) Notwithstanding the foregoing provisions of this Section
10.4, Buyer shall be free to sell or otherwise transfer the Transferred
Assets and/or the Subject Agreements to any Affiliate of either Buyer
or Seller with no obligation to advise Seller of such sale or transfer
and without the creation of the rights provided Seller in this Section
10.4.

(e) Any purchase by Seller under this Section 10.4 shall close
within sixty (60) days of Seller's notice of acceptance. Such period of
time shall be extended as reasonably necessary to obtain all required
regulatory approvals, if any. Buyer and Seller shall use all reasonable
efforts to effectuate any such transfer. The failure of Seller to close
within such time period, unless due to the fault of Buyer, shall permit
Buyer to sell or transfer the assets in question without obligation to
Seller.

(f) In the event of a sale or transfer to Seller pursuant to
10.4(b) or (c), both Parties will be released from all obligations
under the Project Documents except for

-26-
31

those that continue beyond termination of their respective agreement,
and Seller shall be released from the obligations of Article IX hereof.

10.5 Additional Undertakings. Seller will deliver to Buyer,
sufficiently prior to the Closing Date so that Buyer may have reasonable
opportunity to inspect same, a true and correct, detailed list of (i) all
permits and other items described in Section 5.3(b), and (ii) all items
comprising the Transferred Assets, each list providing such information as Buyer
may reasonably request. Additionally, Seller will deliver to Buyer within six
(6) months of the Closing Date a list of all Producer Contracts in effect as of
the Effective Date, including accurate and complete information with respect to
the contract number, date, contract parties, term of agreement and whether such
Producer Contract provides for fractionation of liquids by Seller or an
Affiliate for each such contract.

10.6 Identification of Buyer's Property. Seller will cooperate with
Buyer in permitting Buyer to place appropriate signs or other notices on the
Transferred Assets to indicate ownership of such assets by Buyer. Such signs or
other notices shall be reasonable in terms of size and location.

10.7 Interim Operations. During the period beginning on the
Effective Date and ending on the Closing Date, Seller agrees that it will
operate the Transferred Assets as called for by the O&M Agreement as if such
agreement were in effect. The Parties agree that during this interim operating
period the Parties will receive the economic benefit of such operations of the
Transferred Assets as fully and completely as if the Purchase Documents were in
effect. Should the Closing not occur, however, the operations of the Transferred
Assets during this interim period shall be solely for the account of Seller.

ARTICLE XI
INDEMNIFICATION

11.1 SELLER'S INDEMNITY. Assuming the Closing occurs and subject to
the provisions of this Article XI, Seller agrees to indemnify, defend and hold
Buyer and its Affiliates and their respective officers, directors, shareholders,
unitholders, members, managers, agents, employees, representatives, successors
and assigns (said persons being sometimes referred to in this Section 11.1 as
"Buyer Indemnitees") harmless from and against and in respect of any Claims and
Losses (collectively the "Buyer's Damages"), arising out of or resulting from,
and shall pay the Buyer Indemnitees the full amount of Buyer's Damages that
Buyer Indemnitees may be obligated to pay on account of:

(a) any misrepresentation, breach of warranty or failure to
perform any covenant or agreement made or undertaken by Seller in this
Agreement or any misrepresentation in or omission from any other
agreement, certificate, Schedule, Exhibit or writing delivered to Buyer
pursuant to this Agreement;

(b) the Retained Liabilities; or

(c) The ownership or operation of the Transferred Assets , or
the creation, existence or occurrence of any fact or event on or prior
to the Effective Time related to the operation of the Transferred
Assets.

-27-
32

11.2 ENVIRONMENTAL INDEMNIFICATION. Assuming the Closing occurs,
Seller agrees to indemnify, defend and hold each Buyer Indemnitee harmless from
and against and in respect of any and all Environmental Liabilities that may be
imposed upon or incurred by Buyer, arising out of or in connection with (a) the
acts or omissions of any Person prior to the Effective Time relating to the
ownership or operation of the Transferred Assets, or any business conducted at
the Plants; (b) any act or omission of Seller relating to the Plants (other than
an act or omission by Buyer in the operation of the Transferred Assets after the
Effective Time, but excluding Buyer's failure to detect or remedy any existing
environmental conditions or any Environmental Liabilities existing on or prior
to the Effective Time); or (c) any breach by Seller of a representation or
warranty contained in Section 5.10 (collectively, "Environmental Losses").

11.3 BUYER'S INDEMNITY. Assuming the Closing occurs and subject to
the provisions of this Article XI and the provisions of the other Purchase
Documents (the indemnification provisions of which shall control over the
provisions of this Section 11.3), Buyer agrees to indemnify, defend and hold
Seller and its Affiliates and their respective officers, directors,
shareholders, unitholders, members, managers, agents, employees,
representatives, successors and assigns (said persons being sometimes referred
to in this Section 11.3 as the "Seller Indemnitees") harmless from and against
any Claims and Losses (collectively "Seller's Damages"), arising out of or
resulting from, and shall pay the Seller Indemnitees the full amount of Seller's
Damages that the Seller Indemnitees may be obligated to pay on account of:

(a) any misrepresentation, breach of warranty or failure to
perform any covenant or agreement made or undertaken by Buyer in this
Agreement or any misrepresentation in or omission from any other
agreement, certificate, Schedule, Exhibit or writing delivered to
Seller pursuant to this Agreement;

(b) The ownership or operation of the Transferred Assets, or
the creation, existence or occurrence of any fact or event subsequent
to the Effective Time related to the operation of the Transferred
Assets; or

(c) Any and all Environmental Liabilities that may be imposed
upon or incurred by Seller, arising out of or in connection with the
acts or omissions of any Person (other than Seller) on and after the
Effective Time relating to the Transferred Assets,

11.4 PROCEDURE. All claims for indemnification by a party under
this Article XI (the party claiming indemnification and the party against whom
such claims are asserted being hereinafter called the "Indemnified Party" and
the "Indemnifying Party", respectively) shall be asserted and resolved as
follows:

(a) In the event that any Claim for which an Indemnifying
Party would be liable to an Indemnified Party hereunder is asserted
against or sought to be collected from such Indemnified Party by a
third party, such Indemnified Party shall, within 45 calendar days of
the receipt thereof, give notice (the "Claim Notice") to the
Indemnifying Party of such Claim, specifying the nature of and specific
basis for such Claim and the amount or the estimated amount thereof to
the extent then feasible, which estimate shall not be binding upon the
Indemnifying Party in its effort to collect the final amount of such
Claim. The failure to give any such notice shall not affect the

-28-
33

rights of the Indemnified Party to indemnification hereunder unless the
Indemnified Party has proceeded to contest, defend or settle the Claim
with respect to which it has failed to give prior notice to the
Indemnifying Party. Additionally, to the extent the Indemnifying Party
is prejudiced thereby, the failure to so notify the Indemnifying Party
of any such Claims shall relieve the Indemnifying Party from liability
that it may have to the Indemnified Party under the indemnification
provisions contained in this Article XI, but only to the extent of the
loss directly attributable to such failure to notify, and shall not
relieve the Indemnifying Party from any liability that it may have to
the Indemnified Party otherwise than under this Article XI.

(b) The Indemnifying Party shall be given the opportunity, at
its cost and expense, to contest and defend by all appropriate legal
proceedings any Claim with respect to which it is called upon to
indemnify the Indemnified Party under the provisions of this Agreement;
provided, however, that notice of the intention so to contest and
defend shall be delivered by the Indemnifying Party to the Indemnified
Party within thirty (30) days following receipt of the notice provided
for in Section 11.4(a) above. If the Indemnifying Party does not give
notice to the Indemnified Party of its election to contest and defend
any such Claim within such period then the Indemnifying Party shall be
bound by the result obtained with respect thereto by the Indemnified
Party and shall be responsible for all costs incurred in connection
therewith. The Claim which the Indemnifying Party elects to contest and
defend may be conducted in the name and on behalf of the Indemnifying
Party or the Indemnified Party as may be appropriate. Such Claim shall
be conducted by counsel employed by the Indemnifying Party who shall be
reasonably satisfactory to the Indemnified Party, and the Indemnified
Party shall have the right to participate in such Claim and to be
represented by counsel of its own choosing at its cost and expense. If
the Indemnified Party joins in any such Claim, the Indemnifying Party
shall have full authority to determine all action to be taken with
respect thereto; provided that if the Indemnifying Party reserves its
rights with respect to its indemnification obligations under this
Agreement as to such Claim, then the Indemnified Party shall have the
full authority to determine all action to be taken with respect
thereto. At any time after the commencement of defense of any Claim,
the Indemnifying Party may request the Indemnified Party to agree in
writing to the abandonment of such contest or to the payment or
compromise by the Indemnifying Party of the asserted Claim, provided
the Indemnifying Party agrees in writing to be solely liable for all
losses relating to such Claim; whereupon such action shall be taken
unless the Indemnified Party determines that the contest should be
continued and notifies the Indemnifying Party in writing within fifteen
(15) days of such request from the Indemnifying Party. In the event
that the Indemnified Party determines that the contest should be
continued, the amount for which the Indemnifying Party would otherwise
be liable hereunder shall not exceed the amount which the Indemnifying
Party had agreed to pay in payment or consideration of such Claim,
provided the other party to the contested Claim had agreed in writing
to accept such amount in payment or compromise of the Claim as of the
time the Indemnifying Party made its request therefor to the
Indemnified Party, and further provided that, under such proposed
compromise, the Indemnified Party would be fully and completely
released from any further liability or obligation with respect to the
matters which are the subject of such contested Claim.

-29-
34

(c) If requested by the Indemnifying Party, the Indemnified
Party agrees, at the Indemnifying Party's expense, to cooperate with
the Indemnifying Party and its counsel in contesting any Claim that the
Indemnifying Party elects to contest, or, if appropriate and related to
the Claim in question, in making any counterclaim against the person
asserting the third party Claim, or any cross-complaint against any
person other than an affiliate of the Indemnified Party.

(d) If any Indemnified Party should have a Claim against the
Indemnifying Party hereunder that does not involve a Claim being
asserted against or sought to be collected from it by a third party,
the Indemnified Party shall send a Claim Notice with respect to such
Claim to the Indemnifying Party. If the Indemnifying Party disputes
such Claim, such dispute shall be resolved in the manner set forth in
Article XV hereof.

(e) The Indemnified Party agrees to afford the Indemnifying
Party and its counsel the opportunity, at the Indemnifying Party's
expense, to be present at, and to participate in, conferences with all
Persons, asserting any Action against the Indemnified Party and
conferences with representatives of or counsel for such Persons.

11.5 INDEMNIFICATION THRESHOLD. Neither Seller nor Buyer shall be
obligated to indemnify the other Party until the Buyer's Damages or Seller's
Damages, as may be the case, have exceeded in the aggregate $100,000, and then
such Indemnifying Party's obligation to indemnify shall apply only to such
excess amounts.

11.6 EXPRESS NEGLIGENCE. TO THE EXTENT A PARTY HEREUNDER IS
ENTITLED TO INDEMNIFICATION UNDER THIS ARTICLE XI, SUCH INDEMNIFICATION SHALL
APPLY NOTWITHSTANDING THE NEGLIGENCE, GROSS NEGLIGENCE, WILLFUL OR OTHER ACT BY
THE PARTY TO BE SO INDEMNIFIED AND NOTWITHSTANDING SUCH ACT MAY OCCUR IN THE
FUTURE, IT BEING THE INTENT OF THE PARTIES HERETO THAT SUCH INDEMNIFICATION
SHALL APPLY TO ALL SUCH ACTS.

-30-
35

(c) Seller, if a material default shall be made by Buyer in
the observance or performance by Buyer of any agreements and covenants

(d) Buyer, if Seller has been unable to satisfy all conditions
to the Closing set forth in Section 7.1 by June 1, 1998; or

(e) Seller, if Buyer has been unable to satisfy all conditions
to the Closing set forth in Section 7.2 by June 1, 1998.

12.3 LIABILITY UPON TERMINATION. If the obligation to close the
transactions contemplated by this Agreement is terminated pursuant to any
provision of Section 12.2, then neither party shall be under any liability to
the other party hereto other than as provided in Section 2.3(a) hereof;
provided, however, that nothing herein shall relieve any party from liability
for any breach of or default under this Agreement occurring prior to such
termination. Except as set forth in this Section 12.3, the rights of the parties
shall not terminate upon the failure to close the transactions contemplated
hereby. Buyer shall have the right to specific performance if the Agreement is
not otherwise terminated.

OF COVENANTS, REPRESENTATIONS,
WARRANTIES AND AGREEMENTS

All statements of fact contained in any written statement, certificate,
instrument or document delivered by or on behalf of Seller or Buyer pursuant to
this Agreement or in connection with the transactions contemplated hereby shall
be deemed representations and warranties of Seller or Buyer, respectively. All
representations, warranties, covenants and agreements made by the Parties in
this Agreement or pursuant hereto shall survive the Closing without limit,
except as hereinafter provided, notwithstanding any investigation heretofore or

warranties of the Parties shall survive until the tenth anniversary of the
Effective Time.

ARTICLE XIV

ARTICLE XV
DISPUTES

15.1 Negotiation. In the event of any controversy or claim, whether
based in contract, tort or otherwise, arising out of or relating to this
Agreement or the scope, breach, termination or validity of this Agreement (a
"Claim"), the Parties shall promptly seek to resolve any such Claim by
negotiations between senior executives of the Parties who have authority to
settle the Claim. When a Party believes there is a Claim under this Agreement,
that Party will give the other Party written notice of the Claim. Within thirty
(30) days after receipt of such notice, the receiving Party shall submit to the
other a written response. Both the notice and response shall include (i) a
statement of each Party's position and a summary of the evidence and arguments
supporting its position, and (ii) the name, title, fax number, and telephone
number of the executive who will represent that Party. In the event the Claim
involves a claim arising out of the actions of any person or entity not a
signatory to this Agreement, the receiving Party shall have such additional time
as necessary, not to exceed an additional thirty (30) days, to investigate the
Claim before submitting a written response. The executives shall meet at a
mutually acceptable time and place within fifteen (15) days after the date of
the response and thereafter as often as they reasonably deem necessary to
exchange relevant information and to attempt to resolve the Claim. If one of the
executives intends to be accompanied at a meeting by an attorney, the other
executive shall be given at least five (5) working days' notice of such
intention and may also be accompanied by an attorney. All negotiations and
communications pursuant to this Article 15 shall be treated and maintained by
the Parties as confidential information and shall be treated as compromise and
settlement negotiations for the purposes of the Federal and State Rules of
Evidence .

15.2 Failure to Resolve. If the Claim has not been resolved within
sixty (60) days after the date of the response given pursuant to Section 15.1
above, or such additional time, if any, that the Parties mutually agree to in
writing, or if the Party receiving such notice denies the applicability of the
provisions of Section 15.1 or otherwise refuses to participate under the
provisions of Section 15.1, either Party may initiate binding arbitration
pursuant to the provisions of Section 15.3 below.

15.3 Arbitration. Any Claims not settled pursuant to the foregoing
provisions shall be submitted to binding arbitration in accordance with the
following provisions. Arbitration shall be the sole and exclusive remedy of the
Parties in connection with any Claims hereunder.

(a) The Party desiring to initiate arbitration in connection with
any Claim shall send, via certified mail, written notice of
demand of arbitration to the other Party and the name of the
arbitrator appointed by the Party demanding arbitration
together with a statement of the matter in controversy.

-32-
37

Judge for the District of Colorado or such other person
designated by such judge. The two arbitrators so selected
shall within fifteen (15) days after their designation select
a third arbitrator; provided, however, that if the two
arbitrators are not able to agree on a third arbitrator within
such 15-day period, either Party may request the Chief U.S.
District Court Judge for the District of Colorado or such
other person designated by such judge to select the third
arbitrator as soon as possible. In the event the Judge
declines to appoint an arbitrator, appointment shall be made,
upon application of either Party, pursuant to the Commercial
Arbitration Rules of the American Arbitration Association. If
any arbitrator refuses or fails to fulfill his or her duties
hereunder, such arbitrator shall be replaced by the Party
which selected such arbitrator (or if such arbitrator was
selected by another Person, through the procedure which such
arbitrator was selected) pursuant to the foregoing provisions.

(d) Each arbitrator selected by the Parties shall be a certified
public accountant or licensed attorney with at least fifteen
(15) years of oil and gas experience as a certified public
accountant and/or practicing attorney. The arbitrators
selected by the Parties are not required to be neutral, but
the third arbitrator shall be neutral and shall be a certified
public accountant. If neither of the arbitrators appointed by
or on behalf of the Parties is a retired judge, then the third
arbitrator shall be a retired judge.

(e) The Parties hereto hereby request and consent to the three (3)
arbitrators conducting a hearing in Denver, Colorado no later
than sixty (60) days following their selection or thirty (30)
days after all prehearing discovery has been completed,
whichever is later, at which the Parties shall present such
evidence and witnesses as they may choose, with or without
counsel.

(f) Arbitration shall be conducted in accordance with the
Commercial Arbitration Rules and procedures of the American
Arbitration Association.

(g) The Federal Rules of Civil Procedure, as modified or
supplemented by the local rules of civil procedure for the
U.S. District Court of Colorado, shall apply in the
arbitration. The Parties shall make their witnesses available
in a timely manner for discovery pursuant to such rules. If a
Party fails to comply with this discovery agreement within the
time established by the arbitrators, after resolving any
discovery disputes, the arbitrators may take such failure to
comply into consideration in reaching their decision. All
discovery disputes shall be resolved by the arbitrators
pursuant to the procedures set forth in the Federal Rules of
Civil Procedure.

(h) Adherence to formal rules of evidence shall not be required.
The arbitrators shall consider any evidence and testimony that
they determine to be relevant.

(i) The Parties hereto hereby request that the arbitrators render
their decision within thirty (30) calendar days following
conclusion of the hearing.

-33-
38

(j) Any decision by a majority of the arbitration panel shall be
final, binding and non-appealable. Any such decision may be
filed in any court of competent jurisdiction and may be
enforced by any Party as a final judgment in such court. There
shall be no grounds for appeal of any arbitration award
hereunder.

(k) The defenses of statute of limitations and laches shall be
tolled from and after the date a Party gives the other Party
written notice of a Claim as provided in Section 15.1 above
until such time as the Claim has been resolved pursuant to
Section 15.1 , or an arbitration award has been entered
pursuant to Section 15.3.

15.4 Recovery of Costs and Attorneys' Fees. In the event
arbitration (or, despite the Parties agreement to the Claims through binding
arbitration, litigation) arising out of this Agreement is initiated by either
Party, the prevailing Party, after the entry of a final non-appealable order,
shall be entitled to recover from the other Party, as a part of said order, all
court costs, fees and expenses of such arbitration (or litigation), including,
without limitation, reasonable attorneys' fees.

15.5 Choice of Forum. If, despite the Parties' agreement to submit
any Claims to binding arbitration, there are any court proceedings arising out
of or relating to this Agreement or the transactions contemplated hereby, such
proceedings shall be brought and tried in the federal or state courts situated
in the City and County of Denver, Colorado.

15.6 Jury Waivers. THE PARTIES HEREBY WAIVE ANY AND ALL RIGHTS TO
DEMAND A TRIAL BY JURY.

15.7 Limitation of Damages. WHETHER OR NOT OCCASIONED BY A DEFAULT
OR OTHER BREACH OF THIS AGREEMENT, NEITHER PARTY SHALL BE LIABLE TO THE OTHER
PARTY FOR SPECIAL, EXEMPLARY OR PUNITIVE DAMAGES, LOSS OF PROFITS, OR
CONSEQUENTIAL DAMAGES.

15.8 Governing Law. THIS AGREEMENT SHALL BE CONSTRUED AND ENFORCED
IN ACCORDANCE WITH, AND THE RIGHTS OF THE PARTIES SHALL BE GOVERNED BY, THE LAW
OF THE STATE OF COLORADO, WITHOUT REGARD TO ANY CONFLICT-OF-LAWS PROVISION
THEREOF THAT WOULD OTHERWISE REQUIRE THE APPLICATION OF THE LAW OF ANY OTHER
JURISDICTION.

15.9 LIMITATION OF DAMAGES. WHETHER OR NOT OCCASIONED BY A DEFAULT
OR OTHER BREACH OF THIS FRAC AGREEMENT, NEITHER PARTY SHALL BE LIABLE TO THE
OTHER FOR SPECIAL DAMAGES, EXEMPLARY OR PUNITIVE DAMAGES, LOSS OF PROFITS, OR
CONSEQUENTIAL DAMAGES.

ARTICLE III
DUKE ENERGY'S RIGHTS AND OBLIGATIONS

3.1 Commitment to Process Dedicated Gas and Deliver Raw Product. Duke
Energy shall cause the Dedicated Gas to be processed and all Raw Product to be
delivered to TEPPCO at the Receipt Points for fractionation under the terms of
this Agreement, except as excluded pursuant to Section 3.2; provided, however,
if due to legitimate operational constraints or restrictions Duke Energy is
unable to process certain volumes of Dedicated Gas and deliver the Raw Product
derived therefrom to TEPPCO, then, provided that Duke Energy (i) notifies TEPPCO
of the occurrence of such operational constraints or restrictions as soon as
reasonably possible and (ii) uses commercially reasonable efforts to remove such
operational constraints and/or restrictions as soon as reasonably possible, Duke
Energy shall be relieved of its obligation to deliver such volumes of Raw
Product to TEPPCO for fractionation hereunder to the extent, and only to the
extent, that such operational constraints or restrictions exist and prevent such
delivery. TEPPCO acknowledges that as of the date hereof, Duke Energy is
diverting certain volumes of Dedicated Gas to Amoco's Wattenberg Natural Gas
Processing Plant due to legitimate operational constraints.

3.2 Exclusions. Any volumes of Raw Product in excess of those which
TEPPCO is able to physically accept for delivery and fractionate pursuant to
Article IV, are excepted from Duke Energy's commitment in Section 3.1.

3.3 Delivery of Raw Product. Duke Energy shall use commercially
reasonable efforts to deliver Raw Product to TEPPCO at the Receipt Points at a
flow rate that the Fractionators are physically capable of handling.

-8-
78

3.4 No Reduction of Raw Product Volume.

(a) If Duke Energy enters into a Compensable Amendment, then Duke
Energy shall keep TEPPCO whole for any loss of Specification Products
attributable thereto by paying to TEPPCO, within thirty (30) days after any such
loss first occurs, liquidated damages calculated in accordance with the
Liquidated Damages Formula, assuming that (i) V is equal to the annual
Specification Product volume (in Gallons) that would have been lost during the
immediately preceding Year if such loss had occurred one Year earlier, (ii) N is
equal to the Fractionation Fee that would have been paid on the Lost
Specification Products attributable to such Compensable Amendment and (iii) A is
equal to the contract Year in which such loss occurs; provided, however, if the
cumulative effect of all losses occurring during any twelve (12) month period
(an "Adjustment Period") attributable to Compensable Amendments is a reduction
in the volumes of Specification Products delivered by TEPPCO to Duke Energy
during the Adjustment Period by an amount in excess of twenty-five percent (25%)
of the volumes of Specification Products delivered by TEPPCO to Duke Energy in
the twelve (12) month period immediately preceding such Adjustment Period, then
TEPPCO shall have the right, at its option, to terminate the Project Agreements
and Duke Energy shall pay to TEPPCO within ten (10) days after any such
termination, liquidated damages calculated in accordance with the Liquidated
Damages Formula; and further provided, and except as provided in (c) below Duke
Energy shall not be required to pay a Fractionation Fee to TEPPCO on Lost
Specification Products on which Duke Energy had previously paid liquidated
damages to TEPPCO. The Parties agree that the actual damages to TEPPCO in the
event of a Compensable Amendment are impractical to ascertain and the amount of
the liquidated damages as determined in accordance with this Section 3.4 is a
reasonable estimate thereof and TEPPCO's sole and exclusive remedy with respect
thereto.

(b) Duke covenants and agrees to deliver to TEPPCO (i) copies of all
Compensable Amendments promptly after execution thereof and (ii) upon TEPPCO's
request, copies of other amendments to the Dedicated Producer Contracts.

(c) If, subsequent to a loss attributable to a Compensable Amendment,
the volumes of Raw Product attributable to such Compensable Amendment are later
delivered by Duke Energy to TEPPCO for fractionation in the Fractionators, then
Duke Energy shall pay to TEPPCO a Fractionation Fee on the amount, if any, by
which (i) the actual volumes of Lost Specification Products attributable to such
Compensable Amendment in each Year during the remainder of the term hereof
exceeds (ii) the volumes of Lost Specification Products attributable to such
Compensable Amendment on which TEPPCO was paid liquidated damages pursuant to
the Liquidated Damages Formula for each such Year.

3.5 Obligation to Obtain Right to Fractionate. With respect to any
future agreement that Duke Energy or any of its Affiliates enters into
pertaining to natural gas that (i) is produced from the Dedicated Lands, (ii) is
transported through any of the Dedicated Gathering Pipelines, (iii) becomes
subject to a Dedicated Producer Contract or (iv) is processed in any of the
Dedicated Plants, Duke Energy shall use commercially reasonable efforts to
obtain, or cause its Affiliate to obtain, the right to process such natural gas
and fractionate the natural gas liquids derived therefrom.

3.6 Sale or Conveyance of Dedicated Assets by Duke Energy. If, during
the term of this Agreement, Duke Energy or any of its Affiliates desires to

control, rights, titles or other interests in and to all or any part of any of
this Agreement, the Dedicated Gas, Dedicated Producer Contracts, the Dedicated
Gathering Pipelines and/or the Dedicated Plants (collectively, the "Dedicated
Assets") then Duke Energy shall notify TEPPCO in writing of any such Sale (a
"Sale Notice") and the identity of the purchaser at least sixty (60) days prior
to the proposed closing of any such sale. The rights of TEPPCO with respect to
any such Sale shall then be determined by the nature of such Sale as follows:

A. If such Sale involves all or a material part of (i) the Dedicated
Assets and/or (ii) Duke Energy's interest in this Agreement, upon
the receipt of a Sale Notice, TEPPCO shall have the right to
terminate this Agreement effective as of the closing of such Sale
by delivering written notice of termination to Duke Energy within
thirty (30) days after receipt of the Sale Notice. If TEPPCO elects
to terminate this Agreement pursuant to the immediately preceding
sentence, then Duke Energy and TEPPCO shall be relieved of all
further obligations and liabilities under the Project Agreements as
of the closing of the Sale, except for those obligations and
liabilities that survive termination, and within ten (10) days
after such termination, (i) Duke Energy shall pay to TEPPCO

further obligations and liabilities accruing after the
date of assignment under (1) the Lease and (2) the O&M
Agreement to the extent applicable to the Greeley
Fractionator; and

(b) if such Sale also includes the Spindle Plant, then, as
of the closing, Duke Energy shall be relieved of all
further obligations and liabilities accruing after the
date of assignment under (1) the Sublease and (2) the
O&M Agreement to the extent applicable to the Spindle
Fractionator as of the closing of the Sale; or

(2) if such Sale does not involve an assignment of Duke
Energy's interest in this Agreement, and as a result of
such Sale, there are Lost Specification Products, then
Duke Energy shall keep TEPPCO whole for such loss by
paying to TEPPCO, within thirty (30) days after the closing
of such Sale, liquidated damages calculated in accordance
with the Liquidated Damages Formula, assuming that (i) V is
equal to the annual Specification Product volume (in
Gallons) attributable to the Dedicated Assets sold for
the Year immediately preceding the date of closing of such
Sale, (ii) N is equal to the Fractionation Fee that would
have been paid on the Lost Specification Products
attributable to such Sale and (iii) A is equal to the
contract Year in which the date of closing of such Sale
occurs.

B. If such Sale does not involve a material part of the Dedicated
Assets or Duke Energy's interest in this Agreement, and as a result
of such Sale, there are Lost Specification Products, then Duke
Energy shall keep TEPPCO whole for such loss by paying to TEPPCO,
within thirty (30) days after the closing of such Sale, liquidated
damages calculated in accordance with the Liquidated Damages
Formula, assuming that (i) V is equal to the annual Specification
Product volume (in Gallons) attributable to the Dedicated Assets
sold for the Year immediately preceding the date of closing of such
Sale, (ii) N is equal to the Fractionation Fee that would have been
paid on the Lost Specification Products attributable to such Sale
and (iii) A is equal to the contract Year in which the date of
closing of such Sale occurs.

As used in this Section 3.6, the term "material" shall mean, individually or in
the aggregate, any Sale or Sales of Dedicated Assets which produce, gather,
transport and/or process natural gas and/or natural gas liquids which contribute
more than ten percent (10%) of the Raw Product volumes as reasonably estimated
at the time of the Sale. The Parties agree that the actual damages to TEPPCO in
the event of a Sale are impractical to ascertain and the amount of the
liquidated damages as determined in accordance with this Section 3.6 is a
reasonable estimate thereof and TEPPCO's sole and exclusive remedy with respect
thereto.

ARTICLE IV
TEPPCO'S RIGHTS AND OBLIGATIONS

4.1 Commitment to Fractionate. Subject to the physical capacity and
capabilities of the Fractionators, TEPPCO shall accept delivery of and provide
fractionation on a firm basis for (i) up to a maximum of 378,000 Gallons per Day

the Specification Products are delivered to Duke Energy at the Delivery Points.
Title to the Raw Product and the Specification Products shall remain in Duke
Energy at all times. TEPPCO shall at no time take title to the Raw Product or
the resulting Specification Products. TEPPCO shall not encumber or cause to be
encumbered Specification Products returned to Duke Energy.

ARTICLE VI
MEASUREMENT, QUALITY AND DELIVERY PRESSURE OF RAW PRODUCT

6.1 Measurement. Volumes of Specification Products shall be measured
according to one of the following procedures:

(a) By scaled weight based on GPA Standard 8186-86 (Measurement of
Liquid Hydrocarbons by Truck Scales);

(b) By mass measurement based on Chapter 4 (Proving Systems), Chapter 5
(Liquid Metering) and Chapter 14.7 (Mass Measurement of Natural Gas Liquids) of
the American Petroleum Institute Manual of Petroleum Measurement Standards and
(ii) calculated based on Chapter 14.4 (Converting Mass of Natural Gas Liquids
and Vapors to Equivalent Liquid Volumes) of the American Petroleum Institute
Manual of Petroleum Measurement Standards; or

(c) Ethane (C2) shall be measured in a vapor phase by orifice
measurement based on API Chapter 21 (Flow Measurement Using Electronic Metering
Systems) and API Chapter 14-3 (Natural Gas Fluids Measurement, Concentric,
Square-Edged Orifice Meters).

6.2 Quality. Raw Product delivered by Duke Energy to TEPPCO at the
Receipt Points shall not be deleterious to the operation of, or otherwise cause
damage to, the Fractionators. TEPPCO shall have the right to reject, and refuse
to fractionate, any Raw Product which does not meet such standards.

6.3 Delivery Pressure. Raw Product shall be delivered by Duke Energy to
TEPPCO at the Receipt Points at sufficient pressure to maintain the Raw Product
in a liquid state at all times. TEPPCO shall have the right to reject, and
refuse to fractionate, any Raw Product which is not in a liquid state.

6.4 Greeley Frac Measurement. Gallons of Specification Products
delivered by TEPPCO at the Greeley Fractionator shall be measured and calculated
as follows:

-13-
83

multiplying the number of MCF's contained in the vapor stream
times the GPM's which are attributable to C2 (ethane) and heavier
components of the vapor.

(b) The Specification Product recovered as a liquid shall be measured

as follows: the ending tankage inventory minus beginning tankage
inventory plus sales of the Specification Product less the
Specification Product delivered to the Greeley Fractionator from
the Spindle Plant.

6.5 Spindle Frac Measurement. Gallons of Specification Products
delivered by TEPPCO at the Spindle Fractionator shall be measured and calculated
as follows:

(a) With respect to ethane recovered as a vapor, the vapors shall be
measured to determine the volume measured in thousand cubic feet
("MCF") and sampled to determine the gallons per MCF ("GPM"); then
the gallons are determined by multiplying the number of MCF's
contained in the vapor stream times the GPM's which are
attributable to C2 (ethane) and heavier components of the vapor.

(b) The Specification Product recovered as a liquid shall be measured
as follows: the ending tankage inventory minus beginning tankage
inventory plus sales of the Specification Product (including
deliveries to the Greeley Fractionator) plus sales of
Specification Product delivered to the Amoco Pipeline.

ARTICLE VII
COMPENSATION TO TEPPCO

7.1 Fractionation Fee for Initial Period. As full consideration for the
fractionation services provided hereunder, Duke Energy shall pay to TEPPCO a fee

ARTICLE V
TAXES, ASSESSMENTS

5.1 Duke Energy's Obligation to Pay. Duke Energy shall pay during
the term of this Lease, all federal, state and local real and personal property
ad valorem taxes, assessments, and other governmental charges, general and
special, ordinary and extraordinary, including but not limited to assessments
for public improvements or benefits assessed against the Premises, or
improvements situated thereon, including, without limitation, the Fractionation
Plant, that are payable to any lawful authority assessed against or with respect
to the Premises or the use or operation thereof, including, but not limited to,
any federal, state or local income, gross receipts, withholding, franchise,
excise, sales, use, value added, recording, transfer or stamp tax, levy, duty,
charge or withholding of any kind imposed or assessed by any federal, state or
local government, agency or authority, together with any addition to tax,
penalty, fine or interest thereon, other than state or U.S. federal income tax
imposed upon the taxable income of TEPPCO and any franchise taxes imposed upon

TEPPCO shall have delivered to Duke Energy evidence of such payment) deduct the
amount of such payment from the Rent owed hereunder.

5.2 Manner of Payment. Duke Energy shall pay all Taxes directly
to the applicable taxing authority prior to delinquency and shall promptly
thereafter provide TEPPCO with evidence of such payment. The certificate issued
or given by the appropriate officials authorized or designated by law to issue
or give the same or to receive payment of such Taxes shall be prima facie
evidence of the existence, payment, nonpayment and amount of such Taxes. Duke
Energy, if Duke Energy shall so desire, may contest the validity or amount of
any such Taxes, at Duke Energy's sole cost and expense, by appropriate
proceedings, diligently conducted in good faith. Duke Energy may defer payment
of such Taxes during the pendency of such contest, provided that nothing herein
contained shall be construed to allow such Taxes to remain unpaid for such
length of time as shall permit the Premises, or any part thereof, to be sold by
any Governmental Authority or a lien with respect thereto foreclosed for the
nonpayment of the same.

ARTICLE VI

yet due or which Duke Energy is contesting in good faith, (b) inchoate mechanic
and materialmen liens for construction in progress, (c) inchoate workmen,

ordinary course of business and (d) liens created by TEPPCO (collectively, the
"Permitted Encumbrances").

ARTICLE VII
EMINENT DOMAIN

7.1 Total Condemnation of Premises. If the whole of the Premises
are acquired or condemned by eminent domain for any public or quasi-public use
or purpose, then this Lease shall terminate as of the date title vests in any
public agency. All rentals and other charges owing hereunder shall be prorated
as of such date.

7.2 Partial Condemnation. If any part of the Premises is acquired
or condemned as set forth in Section 5.1, and if in TEPPCO's reasonable opinion
such partial taking or condemnation renders the Premises unsuitable for the
business of TEPPCO, then this Lease shall terminate at TEPPCO's election as of
the date title vests in any public agency, provided TEPPCO delivers to Duke
Energy written notice of such election to terminate within thirty (30) days
following the date title vests in such public agency. In the event of such
termination, all rentals and other charges owing hereunder shall be prorated as
of such effective date of termination.

7.3 Damages. Duke Energy shall be entitled to any award and all
damages payable as a result of any condemnation or taking of the fee of the
Premises. TEPPCO shall have the right to claim and recover from the condemning
authority, but not from Duke Energy, such compensation

-4-
142

as may be separately awarded or recoverable by TEPPCO in TEPPCO's own right on
account of any and all damage to the Fractionation Plant and/or TEPPCO's
business by reason of the condemnation, including loss of value of any unexpired
portion of the term of the Lease, and for or on account of any cost or loss to
which TEPPCO might be put in removing TEPPCO's personal property, fixtures,

Fractionation Plant, from the Premises.

termination of this Lease, however such termination may be brought about, TEPPCO
shall execute and deliver to Duke Energy an instrument, in recordable form,
evidencing the termination of this Lease and the release by TEPPCO of all of
TEPPCO's right, title and interest in and to the Premises existing under and by
virtue of this Lease.

resolve the Disputed Claim.

-13-

such additional time, if any, that the Parties mutually agree to in
writing, or if the Party receiving such notice denies the applicability
of the provisions of Section 10.1 or otherwise refuses to participate
under the provisions of Section 10.1, either Party may initiate binding
arbitration pursuant to the provisions of Section 10.3 below.

10.3 Any Disputed Claims not settled pursuant to the foregoing provisions
shall be submitted to binding arbitration in accordance with the
following provisions. Arbitration shall be the sole and exclusive

any Disputed Claim shall send, via certified mail, written
notice of demand of arbitration to the other Party and the
name of the arbitrator appointed by the Party demanding
arbitration together with a statement of the matter in
controversy.

(b) Within fifteen (15) days after receipt of such demand, the
receiving Party shall name its arbitrator. If the receiving
Party fails or refuses to name its arbitrator within such
15-day period, the second arbitrator shall be appointed, upon
request of the Party demanding arbitration, by the Chief U.S.
District Court Judge for the District of Colorado or such
other person designated by such judge. The two arbitrators so
selected shall within fifteen (15) days after their
designation select a third arbitrator; provided, however, that
if the two arbitrators are not able to agree on a third
arbitrator within such 15-day period, either Party may request
the Chief U.S. District Court Judge for the District of
Colorado or such other person designated by such judge to
select the third arbitrator as soon as possible. In the event
the Judge declines to appoint an arbitrator, appointment shall
be made, upon application of either Party, pursuant to the
Commercial Arbitration Rules of the American Arbitration
Association. If any arbitrator refuses or fails to fulfill his
or her duties hereunder, such arbitrator shall be replaced by
the Party which selected such arbitrator (or if such
arbitrator was selected by another Person, through the
procedure which such arbitrator was selected) pursuant to the
foregoing provisions.

(c) Each arbitrator selected by the Parties shall be a certified
public accountant or licensed attorney with at least fifteen
(15) years of oil and gas experience as a certified public
accountant and/or practicing attorney. The arbitrators
selected by the Parties are not required to be neutral, but
the third arbitrator shall be neutral and shall be a certified
public accountant. If neither of the arbitrators appointed by
or on

-14-
168

behalf of the Parties is a retired judge, then the third
arbitrator shall be a retired judge.

(d) The Parties hereto hereby request and consent to the three (3)
arbitrators conducting a hearing in Denver, Colorado no later
than sixty (60) days following their selection or thirty (30)
days after all prehearing discovery has been completed,
whichever is later, at which the Parties shall present such
evidence and witnesses as they may choose, with or without
counsel.

(e) Arbitration shall be conducted in accordance with the
Commercial Arbitration Rules and procedures of the American
Arbitration Association.

(f) The Federal Rules of Civil Procedure, as modified or
supplemented by the local rules of civil procedure for the

arbitration. The Parties shall make their witnesses available
in a timely manner for discovery pursuant to such rules. If a
Party fails to comply with this discovery agreement within the
time established by the arbitrators, after resolving any
discovery disputes, the arbitrators may take such failure to
comply into consideration in reaching their decision. All
discovery disputes shall be resolved by the arbitrators
pursuant to the procedures set forth in the Federal Rules of
Civil Procedure.

ARTICLE V
TAXES, ASSESSMENTS

during the term of this Sublease, all federal, state and local real and
personal property ad valorem taxes, assessments, and other governmental
charges, general and special, ordinary and extraordinary, including but not
limited to assessments for public improvements or benefits assessed against the
Premises, or improvements situated thereon, including, without limitation, the
Fractionation Plant, that are payable to any lawful authority assessed against
or with respect to the Premises or the use or operation thereof, including, but
not limited to, any federal, state or local income, gross receipts,
withholding, franchise, excise, sales, use, value added, recording, transfer or
stamp tax, levy, duty, charge or withholding of any kind imposed or assessed by
any federal, state or local government, agency or authority, together with any

taxes imposed upon TEPPCO (such taxes and assessments being hereinafter called

promptly thereafter provide TEPPCO with evidence of such payment. The
certificate issued or given by the appropriate officials authorized or

of such Taxes. Duke Energy, if Duke Energy shall so desire, may contest the
validity or amount of any such Taxes, at Duke Energy's sole cost and expense,
by appropriate proceedings, diligently conducted in good faith. Duke Energy
may defer payment of such Taxes during the pendency of such contest, provided
that nothing herein contained shall be construed to allow such Taxes to remain
unpaid for such length of time as shall permit the Premises, or any part
thereof, to be sold by any Governmental Authority or a lien with respect
thereto foreclosed for the nonpayment of the same.

marketable title to the leasehold interest under the Sickler Lease, (ii) Duke
Energy has the right to enter into this Sublease without obtaining the consent
of the lessor under the Sickler Lease and (iii) TEPPCO shall have the right to
the quiet,

-4-
181
peaceful and undisturbed use of the Premises subject only to: (a) liens for
current taxes and assessments not yet due or which Duke Energy is contesting in
good faith, (b) inchoate mechanic and materialmen liens for construction in
progress, (c) inchoate workmen, repairmen, warehousemen, customer, employee and
carriers liens arising in the ordinary course of business and (d) liens created

agrees with TEPPCO that Duke Energy shall observe and timely perform all of the
obligations and liabilities of the lessor under the Sickler Lease.

ARTICLE VII
EMINENT DOMAIN

7.1 Total Condemnation of Premises. If the whole of the
Premises are acquired or condemned by eminent domain for any public or
quasi-public use or purpose, then this Sublease shall terminate as of the date
title vests in any public agency. All rentals and other charges owing
hereunder shall be prorated as of such date.

7.2 Partial Condemnation. If any part of the Premises is
acquired or condemned as set forth in Section 7.1, and if in TEPPCO's
reasonable opinion such partial taking or condemnation renders the Premises
unsuitable for the business of TEPPCO, then this Sublease shall terminate at
TEPPCO's election as of the date title vests in any public agency, provided
TEPPCO delivers to Duke Energy written notice of such election to terminate
within thirty (30) days following the date title vests in such public agency.
In the event of such termination, all rentals and other charges owing hereunder
shall be prorated as of such effective date of termination.

7.3 Damages. Duke Energy shall be entitled to any award and
all damages payable as a result of any condemnation or taking of its leasehold
interest in the Premises. TEPPCO shall have the right to claim and recover
from the condemning authority, but not from Duke Energy, such compensation as
may be separately awarded or recoverable by TEPPCO in TEPPCO's own right on
account of any and all damage to the Fractionation Plant and/or TEPPCO's
business by reason of the condemnation, including loss of value of any
unexpired portion of the term of the Sublease, and for or on account of any
cost or loss to which TEPPCO might be put in removing TEPPCO's personal
property, fixtures, leasehold improvements and equipment, including, without
limitation, the Fractionation Plant, from the Premises.
