                  CSOR Liquidation hereby makes the following representations
and warranties to the Company.

         3.1      ORGANIZATION AND QUALIFICATION.

                  CSOR Liquidation is duly organized, validly existing and in
good standing under the laws of the jurisdiction of its organization, with full
power and authority to own and operate its businesses as presently conducted,
except where the failure to be or have any of the foregoing would not have a
Material Adverse Effect. CSOR Liquidation is duly qualified as a foreign entity
to do business and is in good standing in each jurisdiction where the character
of its properties owned or held under lease or the nature of its activities
makes such qualification necessary, except for such failures to be so qualified
or in good standing as would not, individually or in the aggregate, have a
Material Adverse Effect. CSOR Liquidation has no subsidiaries. True, correct and
complete copies of the Certificate of Formation and Operating Agreement of CSOR
Liquidation, as amended the date, are attached hereto as Exhibit 3.1.

         3.2      AUTHORIZATION; VALIDITY AND EFFECT OF AGREEMENT.

                  CSOR Liquidation has the requisite power and authority to
execute, deliver and perform its obligations under this Agreement and to
consummate the Transactions. The execution and delivery of this Agreement by
CSOR Liquidation and the performance by CSOR Liquidation of its obligations
hereunder and the consummation of the Transactions have been duly authorized by
its Managers and Members and all other necessary company action on the part of
CSOR Liquidation and no other company proceedings on the part of CSOR
Liquidation are


                                       4

<PAGE>

necessary to authorize this Agreement and the Transactions. This Agreement has
been duly and validly executed and delivered by CSOR Liquidation and, assuming
that it has been duly authorized, executed and delivered by the other parties
hereto, constitutes a legal, valid and binding obligation of CSOR Liquidation,
enforceable against it in accordance with its terms, subject to the effects of
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
other similar laws relating to or affecting creditors' rights generally, general
equitable principles (whether considered in a proceeding in equity or at law)
and an implied covenant of good faith and fair dealing.

         3.3      NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

                  Neither the execution and delivery of this Agreement by CSOR
Liquidation nor the performance by CSOR Liquidation of its obligations
hereunder, nor the consummation of the Transactions, will: (i) conflict with
CSOR Liquidation's Certificate of Formation or Operating Agreement; (ii) violate
any statute, law, ordinance, rule or regulation applicable to CSOR Liquidation
or any of the properties or assets of CSOR Liquidation; or (iii) violate,
breach, be in conflict with or constitute a default (or an event which, with
notice or lapse of time or both, would constitute a default) under, or permit
the termination of any provision of, or result in the termination of, the
acceleration of the maturity of, or the acceleration of the performance of any
obligation of CSOR Liquidation under, or result in the creation or imposition of
any Liens upon any properties, assets or business of CSOR Liquidation under, any
material contract or any order, judgment or decree to which CSOR Liquidation is
a party or by which CSOR Liquidation or any of its assets or properties is bound
or encumbered except, in the case of clauses (ii) and (iii), for such
violations, breaches, conflicts, defaults or other occurrences which,
individually or in the aggregate, would not have a Material Adverse Effect or
would not prevent the consummation of this Agreement or the Transactions.

         3.4      INVESTMENT INTENT.

                  The BWP Gas Interests and the BPK Shares (the "Restricted
Securities") being acquired in connection with the Transactions are being
acquired for CSOR Liquidation's own account for investment purposes only and not
with a view to, or with any present intention of, distributing or reselling any
of such Restricted Securities. CSOR Liquidation acknowledges and agrees that the
Restricted Securities have not been registered under the Securities Act or under
any state securities laws, and that the Restricted Securities may not be,
directly or indirectly, sold, transferred, offered for sale, pledged,
hypothecated or otherwise disposed of without registration under the Securities
Act and applicable state securities laws, except pursuant to an available
exemption from such registration. CSOR Liquidation also acknowledges and agrees
that neither the SEC nor any securities commission or other Governmental
Authority has (a) approved the transfer of the Restricted Securities or passed
upon or endorsed the merits of the transfer of the Restricted Securities, this
Agreement or the Transactions; or (b) confirmed the accuracy of, determined the
adequacy of, or reviewed this Agreement. CSOR Liquidation has such knowledge,
sophistication and experience in financial, tax and business matters in general,
and investments in securities in particular, that it is capable of evaluating
the merits and risks of this investment in the Restricted Securities, and CSOR
Liquidation has made such investigations in connection herewith as it deemed
necessary or desirable so as to make an informed investment


                                       5

<PAGE>

decision without relying upon the Company for legal or tax advice related to
this investment. Each of the Members of CSOR Liquidation is an "accredited
investor" within the meaning of Rule 501 promulgated under the Securities Act.

         3.5      BROKERS AND FINDERS FEES.

                  Neither CSOR Liquidation nor any of its officers, directors,
employees or managers has employed any broker or finder or incurred any
liability for any investment banking fees, brokerage fees, commissions or
finders fees in connection with the Transactions for which CSOR Liquidation has
or could have any liability.


                                   ARTICLE IV

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

standing under the laws of its jurisdiction of its organization, with the

have a Material Adverse Effect. The Company is duly qualified as a foreign
corporation or other entity to do business and is in good standing in each
jurisdiction where the character of its properties owned or held under lease or
the nature of its activities makes such qualification necessary, except for such
failures to be so qualified or in good standing as would not have a Material
Adverse Effect.

         4.2      AUTHORIZATION; VALIDITY AND EFFECT OF AGREEMENT.

                  The Company has the requisite corporate power and authority to
execute, deliver and perform its obligations under this Agreement and to

Company and the performance by the Company of its obligations hereunder and the
consummation of the Transactions have been duly authorized by its Board of
Directors and all other necessary corporate action on the part of the Company
and no other corporate proceedings on the part of the Company are necessary to
authorize this Agreement and the Transactions. This Agreement has been duly and
validly executed and delivered by the Company and, assuming that it has been
duly authorized, executed and delivered by the other parties hereto, constitutes
a legal, valid and binding obligation of the Company, in accordance with its
terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and other similar laws relating to or affecting
creditors' rights generally, general equitable principles (whether considered in
a proceeding in equity or at law) and an implied covenant of good faith and fair

         4.3      NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

                  Neither the execution and delivery of the Agreement by the

  rule or regulation, applicable to the Company or any of the properties or
  assets of the Company; or (iii) violate, breach, be in conflict with or

  of, or result in the termination of, the acceleration of the maturity of, or
  the acceleration of the performance of any obligation of the Company, or
  result in the creation or imposition of any Lien upon any properties, assets
  or business of the Company under, any material contract or any order, judgment
  or decree to which the Company is a party or by which it or any of its assets
  or properties is bound or encumbered except, in the case of clauses (ii) and
  (iii), for such violations, breaches, conflicts, defaults or other occurrences
  which, individually or in the aggregate, would not have a material adverse
  effect on its obligation to perform its covenants under this Agreement.

         4.4      BROKERS AND FINDERS.

                  Neither the Company nor any of its officers, directors,
employees or managers has employed any broker or finder or incurred any
liability for any investment banking fees, brokerage fees, commissions or
finders' fees in connection with the Transactions for which the Company has or
could have any liability.

parties shall undertake all necessary steps to ensure that the secrecy and
confidentiality of such information will be maintained in accordance with the
provisions of this subsection (a). Notwithstanding anything contained herein to
the contrary, in the event a party is required by court order or subpoena to
disclose information which is otherwise deemed to be confidential or subject to
the confidentiality obligations hereunder, prior to such disclosure, the
disclosing party shall: (i) promptly notify the non-disclosing party and, if
having received a court order or subpoena, deliver a copy of the same to the
non-disclosing party; (ii) cooperate with the non-disclosing party, at the
expense of the non-disclosing party, in obtaining a protective or similar order
with respect to such information; and (iii) provide only that amount of

                                 INDEMNIFICATION

         7.1      INDEMNIFICATION BY CSOR LIQUIDATION.

                  From and after the Closing Date, CSOR Liquidation shall
indemnify and hold harmless the Company and its respective officers and
directors (each an "Indemnified Party"), from and against any and all demands,
claims, actions or causes of action, judgments, assessments, losses,
liabilities, damages or penalties and reasonable attorneys' fees and related
disbursements (collectively, "Claims") suffered by such Indemnified Party
resulting from or arising out of (i) any inaccuracy in or breach of any of the
representations or warranties made by CSOR Liquidation herein, in any
certificate, or in any other document delivered herewith or otherwise required
hereby at the time they were made, and, except for representations and
warranties that speak as of a specific date or time (which need only be true and
correct as of such date or time), on and as of the Closing Date, (ii) any breach
or nonfulfillment of any covenants or agreements made by CSOR Liquidation, and
(iii) any misrepresentation made by CSOR Liquidation, in each case as made
herein or in the Exhibits annexed hereto or in any closing


                                       13

<PAGE>

certificate, schedule or any ancillary certificates or other documents or
instruments furnished by CSOR Liquidation pursuant hereto or in connection with
the Transactions.

         7.2      INDEMNIFICATION PROCEDURES FOR THIRD-PARTY CLAIM.

                  (a) Upon obtaining Knowledge of any Claim by a third party
  which has given rise to, or is expected to give rise to, a claim for
  indemnification hereunder, the Company shall give written notice ("Notice of
  Claim") of such claim or demand to CSOR Liquidation, specifying in reasonable
  detail such information as the Indemnified Party may have with respect to such
  indemnification claim (including copies of any summons, complaint or other
  pleading which may have been served on it and any written claim, demand,
  invoice, billing or other document evidencing or asserting the same). Subject
  to the limitations set forth in Section 7.2(b) hereof, no failure or delay by
  the Company in the performance of the foregoing shall reduce or otherwise
  affect the obligation of CSOR Liquidation to indemnify and hold the
  Indemnified Party harmless, except to the extent that such failure or delay
  shall have actually adversely affected CSOR Liquidation's ability to defend
  against, settle or satisfy any Claims for which the Indemnified Party entitled
  to indemnification hereunder.

                  (b) If the claim or demand set forth in the Notice of Claim
given by the Company pursuant to Section 7.2(a) hereof is a claim or demand
asserted by a third party, CSOR Liquidation shall have fifteen (15) days after
the date on which Notice of Claim is given to notify the Company in writing of
its election to defend such third party claim or demand on behalf of the
Indemnified Party. If CSOR Liquidation elects to defend such third party claim
or demand, the Company shall make available to CSOR Liquidation and its agents
and representatives all records and other materials that are reasonably required
in the defense of such third party claim or demand and shall otherwise cooperate
with, and assist CSOR Liquidation in the defense of, such third party claim or
demand, and so long as CSOR Liquidation is defending such third party claim in
good faith, the Indemnified Party shall not pay, settle or compromise such third
party claim or demand. If CSOR Liquidation elects to defend such third party
claim or demand, the Indemnified Party shall have the right to participate in
the defense of such third party claim or demand, at such Indemnified Party's own
expense. In the event, however, that such Indemnified Party reasonably
determines that representation by counsel to CSOR Liquidation of both CSOR
Liquidation and such Indemnified Party could reasonably be expected to present
counsel with a conflict of interest, then the Indemnified Party may employ
separate counsel to represent or defend it in any such action or proceeding and
CSOR Liquidation will pay the fees and expenses of such counsel. If CSOR
Liquidation does not elect to defend such third party claim or demand or does
not defend such third party claim or demand in good faith, the Indemnified Party
shall have the right, in addition to any other right or remedy it may have
hereunder, at CSOR Liquidation's expense, to defend such third party claim or
demand; provided, however, that (i) such Indemnified Party shall not have any
obligation to participate in the defense of, or defend, any such third party
claim or demand; (ii) such Indemnified Party's defense of or its participation
in the defense of any such third party claim or demand shall not in any way
diminish or lessen the obligations of CSOR Liquidation under the agreements of
indemnification set forth in this Article VII; and (iii) such Indemnified Party
may not settle any claim without the consent of CSOR Liquidation, which consent
shall not be unreasonably withheld or delayed.


                                       14

<PAGE>

                  (c) CSOR Liquidation and the Company and the other Indemnified
Party, if any, shall cooperate fully in all aspects of any investigation,
defense, pre-trial activities, trial, compromise, settlement or discharge of any
claim in respect of which indemnity is sought pursuant to this Article VII,
including, but not limited to, by providing the other party with reasonable
access to employees and officers (including as witnesses) and other information.

                  (d) Except for third party claims being defended in good
faith, CSOR Liquidation shall satisfy its obligations under this Article VII in
respect of a valid claim for indemnification hereunder which is not contested by
CSOR Liquidation in good faith in cash within thirty (30) days after the date on
which Notice of Claim is given.

         7.3      INDEMNIFICATION PROCEDURES FOR NON-THIRD PARTY CLAIMS.
                  In the event any Indemnified Party should have an
indemnification claim against CSOR Liquidation under this Agreement that does
not involve a claim by a third party, the Indemnified Party shall promptly
deliver notice of such claim to CSOR Liquidation in writing and in reasonable
detail. The failure by any Indemnified Party to so notify CSOR Liquidation shall
not relieve CSOR Liquidation from any liability that it may have to such
Indemnified Party, except to the extent that CSOR Liquidation has been actually
prejudiced by such failure. If CSOR Liquidation does not notify the Indemnified
Party within fifteen (15) Business Days following its receipt of such notice
that CSOR Liquidation disputes such claim, such claim specified by CSOR
Liquidation in such notice shall be conclusively deemed a liability of CSOR
Liquidation under this Article VII and CSOR Liquidation shall pay the amount of
such liability to the Indemnified Party on demand, or in the case of any notice
in which the amount of the claim is estimated, on such later date when the
amount of such claim is finally determined. If CSOR Liquidation disputes its
liability with respect to such claim in a timely manner, CSOR Liquidation and
the Indemnified Party shall proceed in good faith to negotiate a resolution of
such dispute and, if not resolved through negotiations, such dispute shall be
submitted to arbitration pursuant to Section 9.12.

         7.4      LIMITATIONS ON INDEMNIFICATION.

                  No claim for indemnification under this Article VII shall be
  asserted by, and no liability for such indemnify shall be enforced against,
  CSOR Liquidation to the extent the Indemnified Party has theretofore received
  indemnification or otherwise been compensated for such Claim. In the event
  that an Indemnified Party shall later collect any such amounts recovered under
  insurance policies with respect to any Claim for which it has previously
  received payments under this Article VII from CSOR Liquidation, such
  Indemnified Party shall promptly repay to CSOR Liquidation such amount
  recovered.

         7.5      EXCLUSIVE REMEDY.

                  The indemnification provisions of this Article VII (i) shall
be the exclusive remedy following the Closing with respect to breaches thereof,
(ii) shall apply without regard to, and shall not be subject to, any limitation
by reason of set-off, limitation or otherwise and (iii) are intended to be
comprehensive and not to be limited by any requirements of law concerning


                                       15

<PAGE>

prominence of language or waiver of any legal right under any law (including,
without limitation, rights under any workers compensation statute or similar
statute conferring immunity from suit). The obligations of the parties set forth
in this Article VII shall be conditioned upon the Closing having occurred.

                                  ARTICLE VIII

                                   TERMINATION

         8.1      TERMINATION.

                  This Agreement may be terminated at any time prior to the
Closing:

                  (a) by mutual consent of the Company and CSOR Liquidation;

                  (b) by the Company or CSOR Liquidation if any Governmental
Authority shall have issued an injunction, order, decree or ruling or taken any
other action restraining, enjoining or otherwise prohibiting any material
portion of the Transactions and such injunction, order, decree, ruling or other
action shall have become final and nonappealable;

                  (c) by the Company or CSOR Liquidation upon written notice to
the other party if any of the conditions to the Closing set forth in Section 6.1
shall have become incapable of fulfillment by [APRIL 30, 2004], and shall not
have been waived in writing by the Company or CSOR Liquidation, respectively;

                  (d) by the Company upon written notice to CSOR Liquidation if
any of the conditions to the Closing set forth in Section 6.3 shall have become
incapable of fulfillment by [APRIL 30, 2004], and shall not have been waived in
writing by the Company; or

                  (e) by CSOR Liquidation upon written notice to the Company if
any of the conditions to the Closing set forth in Section 6.2 shall have become
incapable of fulfillment and shall not have been waived in writing by CSOR
Liquidation.

         8.2      PROCEDURE AND EFFECT OF TERMINATION.

                  In the event of termination of this Agreement pursuant to
Section 8.1 hereof, written notice thereof shall forthwith be given by the
terminating party to the other party, and, except as set forth below, this
Agreement shall terminate and be void and have no effect and the Transactions
shall be abandoned without any further action by the parties hereto; provided
that, if such termination shall result from the failure of a party to perform a
covenant, obligation or agreement in this Agreement or from the breach by the
Company or CSOR Liquidation of any representation or warranty contained herein,
such party shall be fully liable for any and all damages incurred or suffered by
the other party as a result of such failure or breach. If this Agreement is
terminated as provided herein:

                  (a) each party hereto shall redeliver, and shall cause its
agents (including, without limitation, attorneys and accountants) to redeliver,
all documents, work papers and other


                                       16

material of each party hereto relating to the Transactions, whether obtained
before or after the execution hereof; and

                                   ARTICLE IX

                                  MISCELLANEOUS

         9.1      ENTIRE AGREEMENT.

                  This Agreement and the Schedules and Exhibits hereto contain
the entire agreement between the parties and supercede all prior agreements and
understandings, both written and oral, between the parties with respect to the
subject matter hereof.

         9.2      AMENDMENT AND MODIFICATIONS.

                  This Agreement may not be amended, modified or supplemented
except by an instrument or instruments in writing signed by the party against
whom enforcement of any such amendment, modification or supplement is sought.

         9.3      EXTENSIONS AND WAIVERS.

                  At any time prior to the Closing, the parties hereto entitled
to the benefits of a term or provision may (a) extend the time for the
performance of any of the obligations or other acts of the parties hereto, (b)
waive any inaccuracies in the representations and warranties contained herein or
in any document, certificate or writing delivered pursuant hereto, or (c) waive
compliance with any obligation, covenant, agreement or condition contained
herein. Any agreement on the part of a party to any such extension or waiver
shall be valid only if set forth in an instrument or instruments in writing
signed by the party against whom enforcement of any such extension or waiver is
sought. No failure or delay on the part of any party hereto in the exercise of
any right hereunder shall impair such right or be construed to be a waiver of,
or acquiescence in, any breach of any representation, warranty, covenant or
agreement.

         9.4      SUCCESSORS AND ASSIGNS.

                  This Agreement shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and assigns, provided,
however, that no party hereto may assign its rights or delegate its obligations
under this Agreement without the express prior written consent of the other
party hereto. Except as provided in Article VII, nothing in this Agreement is
intended to confer upon any person not a party hereto (and their successors and
assigns) any rights, remedies, obligations or liabilities under or by reason of
this Agreement.

         9.5      SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS.

                  The representations and warranties contained herein shall
survive the Closing and shall thereupon terminate twelve (12) months from the
Closing, except that the representations contained in Sections 3.1, 3.2, 4.1 and
4.2 shall survive indefinitely. All covenants, conditions, obligations and
agreements contained herein which by their terms contemplate actions following
the Closing shall survive the Closing and remain in full force and effect in
accordance with their terms. The covenants, conditions, obligations and
agreements contained in Section 5.8 shall survive indefinitely. All other
covenants, conditions, obligations and agreements contained herein shall not
survive the Closing and shall thereupon terminate.

         9.6      HEADINGS; DEFINITIONS.

                  The Section and Article headings contained in this Agreement
are inserted for convenience of reference only and will not affect the meaning
or interpretation of this Agreement. All references to Sections or Articles
contained herein mean Sections or Articles of this Agreement unless otherwise
stated. All capitalized terms defined herein are equally applicable to both the
singular and plural forms of such terms.

         9.7      SEVERABILITY.

                  If any provision of this Agreement or the application thereof
  to any Person or circumstance is held to be invalid or unenforceable to any
  extent, the remainder of this Agreement shall remain in full force and effect
  and shall be reformed to render the Agreement valid and enforceable while
  reflecting to the greatest extent permissible the intent of the parties.

         9.8      SPECIFIC PERFORMANCE.

                  The parties hereto agree that in the event that any party
fails to consummate the Transactions in accordance with the terms of this
Agreement, irreparable damage would occur, no adequate remedy at law would exist
and damages would be difficult to determine, and that the parties shall be
entitled to specific performance in such event, without the necessity of proving
the inadequacy of money damages as a remedy, in addition to any other remedy at
law or in equity.

         9.9      EXPENSES.

                  Whether or not the Transactions are consummated, and except as
otherwise expressly set forth herein, all legal and other costs and expenses
incurred in connection with the Transactions shall be paid by the party
incurring such expenses and shall be paid at the Closing.

         9.10     NOTICES.

                  All notices hereunder shall be sufficiently given for all

telefax or other electronic transmission service to the appropriate address or
