SALE AND PURCHASE

Section 2.1   Sale and Purchase.

hereby agrees, 

 5
 

severally and not
jointly, to purchase from BreitBurn, the dollar amount of Purchased Units, set
forth opposite its name on Schedule 2.1 hereto.  Each Purchaser agrees to pay BreitBurn the
Common Unit Price for each Purchased Unit, in each case as set forth in Section
2.1(b).  The respective obligations of
each Purchaser under this Agreement are several and not joint with the
obligations of any other Purchaser, and no Purchaser shall be responsible in
any way for the performance of the obligations of any other Purchaser under
this Agreement.  The failure or waiver of
performance under this Agreement by any Purchaser, or on its behalf, does not
excuse performance by any other Purchaser. 
Nothing contained herein or in any other Basic Document, and no action
taken by any Purchaser pursuant thereto, shall be deemed to constitute the
Purchasers as a partnership, an association, a joint venture or any other kind
of entity, or create a presumption that the Purchasers are in any way acting in
concert or as a group with respect to such obligations or the transactions
contemplated by any Basic Document. 
Except as otherwise provided in this Agreement or in the Registration
Rights Agreement, each Purchaser shall be entitled to independently protect and
enforce its rights, including the rights arising out of this Agreement or out
of the Registration Rights Agreement, and it shall not be necessary for any
other Purchaser to be joined as an additional party in any proceeding for such
purpose.

(a)           Common Units.  The number of Purchased Units to be issued
and sold to each Purchaser shall be equal to the quotient determined by
dividing (i) the amount for such Purchaser under the column entitled “Commitment  Amount” on Schedule 2.1 by (ii) the
Common Unit Price (as defined in Section 2.1(b) below).  The Purchased Units shall have those rights,
preferences, privileges and restrictions governing the Common Units as set
forth in the First Amended and Restated Limited Partnership Agreement of
BreitBurn, dated as of October 10, 2006 (the “Partnership
Agreement”).

(b)           Consideration.  The amount per Common Unit each Purchaser
will pay to BreitBurn to purchase the Purchased Units (the “Common Unit
Price”) shall be $32.00.

Section 2.2   Closing.   The
execution and delivery of the Basic Documents (other than this Agreement), the
delivery of certificates representing the Purchased Units, the payment by each
Purchaser of its respective Commitment Amount and execution and delivery of all
other instruments, agreements and other documents required by this Agreement
(the “Closing”) shall take place on a date (the “Closing Date”)
contemporaneous with the Calumet Closing Date, but on or prior to
June 15, 2007, at the offices of Vinson & Elkins L.L.P., 666
Fifth Avenue, 26th Floor, New York, New York  10103.

Section 2.3   Termination.   Notwithstanding
anything to the contrary contained herein, in the event BreitBurn does not
receive at least $70,000,000 of the Commitment Amounts on the Closing
Date, this Agreement shall automatically terminate and any payments of a
Purchaser’s Commitment Amount received by BreitBurn shall be returned to such
Purchaser within two Business Days.

Laws of the state or other jurisdiction of its incorporation or organization;
(ii) has all requisite power and authority, and has all material governmental
licenses, authorizations, consents and approvals, necessary to own, lease, use
and operate its Properties and carry on its business as its business is now
being conducted as described in the BreitBurn SEC Documents and as will be
conducted following the Calumet Acquisition, except where the failure to obtain
such licenses, authorizations, consents and approvals would not reasonably be
expected to have a BreitBurn Material Adverse Effect.  None of BreitBurn or any of its Subsidiaries
are in default in the performance, observance or fulfillment of any provision
of, in the case of BreitBurn, the Partnership Agreement or its Certificate of
Limited Partnership or, in the case of any Subsidiary of BreitBurn, its
respective certificate of incorporation, certificate of formation, bylaws,
limited liability company agreement, limited partnership agreement or other
similar organizational documents.  Each
of BreitBurn and its Subsidiaries is duly qualified or licensed and in good
standing as a foreign limited partnership, limited liability company or
corporation, as applicable, and is authorized to do business in each
jurisdiction in which the ownership or leasing of its respective Properties or
the character of its respective operations makes such qualification necessary,
except where the failure to obtain such qualification, license, authorization
or good standing would not reasonably be expected to have a BreitBurn Material
Adverse Effect.

Section 3.2   Capitalization and Valid Issuance of Purchased Units.

(a)           The
Purchased Units shall have those rights, preferences, privileges and
restrictions governing the Common Units as set forth in the Partnership
Agreement.

All outstanding Common Units and the limited partner interests
represented thereby have been duly authorized and validly issued in accordance
with applicable Law and the Partnership Agreement and are fully paid (to the
extent required by applicable Law and the Partnership Agreement) and
nonassessable (except as such nonassessability may be affected by matters
described in Sections 17-303, 17-607 and 17-804 of the Delaware Revised Uniform
Limited Partnership Act (the “Delaware LP Act”).  All general partner interests of BreitBurn
have been duly authorized and validly issued in accordance with the Partnership
Agreement.

(c)           Other
than the BreitBurn 2006 Long-Term Incentive Plan, the Washburn Amended and

execution, delivery and performance by the BreitBurn Parties of the Basic
Documents to which they are parties and compliance by the BreitBurn Parties

BreitBurn of the Purchased Units, do not and will not (a) assuming the accuracy

the creation or imposition of any Lien upon or with respect to any of the Properties

Section 3.6 would not, individually or in the aggregate, reasonably likely to
result in a BreitBurn Material Adverse Effect.

BreitBurn Party has all necessary power and authority to execute, deliver and
perform its obligations under the Basic Documents; and the execution, delivery
and performance by each BreitBurn Party of the Basic Documents has been duly
authorized by all necessary action on its part; and the Basic Documents
constitute the legal, valid and binding obligations of the BreitBurn Parties

transfer and similar laws affecting creditors’ rights generally or by general
principles of equity including principles of commercial reasonableness, fair
dealing and good faith.  No approval from
the holders of the Common Units is required in connection with BreitBurn’s
issuance and sale of the Purchased Units to the Purchasers.

Section 3.8   Compliance with Laws.   Neither
BreitBurn nor any of its Subsidiaries is in violation of any judgment, decree

Effect.  BreitBurn and its Subsidiaries

regulatory authorities necessary to conduct their respective businesses, except
where the failure to possess such certificates, authorizations or permits would
not have, individually or in the aggregate, a BreitBurn Material Adverse
Effect, and neither BreitBurn nor any such Subsidiary has received any notice
of proceedings relating to the revocation or modification of any such certificate,
authorization or permit, except where such potential revocation or modification
would not have, individually or in the aggregate, a BreitBurn Material Adverse
Effect.  Neither BreitBurn, nor any of
its Subsidiaries, nor any director, officer, agent, employee or other person
acting on behalf of BreitBurn or any of its Subsidiaries has, in the course of

connection with BreitBurn’s obligations under the Registration Rights
Agreement, no authorization, consent, approval, waiver, license, qualification
or written exemption from, nor any filing, declaration, qualification or
registration with, any Governmental Authority or any other Person is required
in connection with the execution, delivery or performance by any BreitBurn
Party of any of the Basic Documents to which it is a party, except (i) for such
consents, approvals and waivers as have been obtained or, in the case of the
Calumet Asset Purchase Agreement, will be obtained by closing, or (ii) where
the failure to receive such authorization, consent, approval, waiver, license,
qualification or written exemption from, or to make such filing, declaration,
qualification or registration would not, individually or in the aggregate,
reasonably be expected to have a BreitBurn Material Adverse Effect.

Section 3.10   MLP Status.   BreitBurn
has, since its inception in March 2006, met the gross income requirements
of Section 7704(c)(2) of the Code and accordingly BreitBurn is not, and does

Investment Company Act of 1940, as amended.

Section 3.12   Offering.   Assuming
the accuracy of the representations and warranties of the Purchasers contained
in this Agreement, the sale and issuance of the Purchased Units pursuant to
this Agreement are exempt from the registration requirements of the Securities
Act, and neither BreitBurn nor any authorized Representative acting on its
behalf has taken or will take any action hereafter that would cause the loss of
such exemption.

fees or commissions will be payable by BreitBurn to brokers, finders or
investment bankers with respect to the sale of any of the Purchased Units or
the consummation of the transactions contemplated by this Agreement.

for the confidentiality agreements and the Registration Rights Agreement
entered into by and between each of the Purchasers and BreitBurn, there are no
other agreements by, among or between BreitBurn or any of its Affiliates, on
the one hand, and any of the Purchasers or their Affiliates, on the other hand,
with respect to the transactions contemplated hereby nor promises or
inducements for future transactions between or among any of such parties.

Section 3.15   Internal Accounting
Controls.   BreitBurn and its Subsidiaries maintain a system of
internal accounting controls sufficient to provide reasonable assurance that
(i)

 11
 

transactions are executed in accordance with
management’s general or specific authorizations, (ii) transactions are recorded
as necessary to permit preparation of financial statements in conformity with
GAAP and to maintain asset accountability, (iii) access to assets is permitted
only in accordance with management’s general or specific authorization and (iv)
the recorded accountability for assets is compared with the existing assets at
reasonable intervals and appropriate action is taken with respect to any
differences.

Section 3.16   Material Agreements.   BreitBurn has
provided the Purchasers with, or made available to the Purchasers through
the BreitBurn SEC Documents, correct and complete copies of all material
agreements (as defined in Section 601(b)(10) of Regulation S-K promulgated by

existing awards under BreitBurn’s 2006 Long-Term Incentive Plan, the Washburn

Restated Employment Agreement, there are no preemptive rights or other rights
to subscribe for or to purchase, nor any restriction upon the voting or
transfer of, any Common Units or other limited partnership or membership
interests of BreitBurn or any of its Subsidiaries, in each case pursuant to any
other agreement or instrument to which any of such Persons is a party or by
which any one of them may be bound. 
Neither the execution of this Agreement, nor the issuance of the
Purchased Units as contemplated by this Agreement gives rise to any rights for
or relating to the registration of any securities of BreitBurn, other than
pursuant to the Registration Rights Agreement or the Partnership Agreement.

Section 3.18   Insurance.   BreitBurn
and its Subsidiaries are insured against such losses and risks and in such
amounts as BreitBurn believes in its sole discretion to be prudent for its
businesses.  BreitBurn does not have any
reason to believe that it or any Subsidiary will not be able to renew its
existing insurance coverage as and when such coverage expires or to obtain
similar coverage from similar insurers as may be necessary to continue its
business.

Section 3.19   Acknowledgment Regarding Purchase
of Purchased Common Units.   BreitBurn acknowledges and agrees that (i) each of the Purchasers is
participating in the transactions contemplated by this Agreement and the other
Basic Documents at BreitBurn’s
request and BreitBurn has
concluded that such participation is in BreitBurn’s best interest and is consistent with BreitBurn’s objectives and (ii) each of the
Purchasers is acting solely in the capacity of an arm’s length purchaser.  BreitBurn further acknowledges that no Purchaser is
acting or has acted as an advisor, agent or fiduciary of BreitBurn (or in any similar capacity) with
respect to this Agreement or the other Basic Documents and any advice given by
any Purchaser or any of its respective Representatives in connection with this
Agreement or the other Basic Documents is merely incidental to the Purchasers’
purchase of the Purchased Units.  BreitBurn
further represents to each
Purchaser that BreitBurn’s
decision to enter into this Agreement has been based solely on the independent
evaluation of the transactions contemplated hereby by BreitBurn and its Representatives.

Purchaser (i) is duly organized, validly existing and in good standing under
the Laws of its respective jurisdiction of organization and (ii) has all
requisite power, and has all material governmental licenses, authorizations,
consents and approvals, necessary to own its Properties and carry on its
business as its business is now being conducted, except where the failure to
obtain such licenses, authorizations, consents and approvals would not have and
would not reasonably be expected to have a Purchaser Material Adverse Effect.

Section 4.2  Authorization, Enforceability.  Such Purchaser has all necessary power and
authority to execute, deliver and perform its obligations under this Agreement
and the Registration Rights Agreement and to consummate the transactions
contemplated thereby, and the execution, delivery and performance by such
Purchaser of this Agreement and the Registration Rights Agreement has been duly
authorized by all necessary action on the part of the Purchaser; and each of
this Agreement and the Registration Rights Agreement constitute the legal,
valid and binding obligations of such Purchaser, enforceable in accordance with
its terms, except as such enforceability may be limited by bankruptcy,
insolvency, fraudulent transfer and similar laws affecting creditors’ rights
generally or by general principles of equity, including principles of
commercial reasonableness, fair dealing and good faith.

Section 4.3  No Breach.  The
execution, delivery and performance by such Purchaser of this Agreement and the
Registration Rights Agreement to which it is a party and all other agreements
and instruments in connection with the transactions contemplated by this
Agreement and the Registration Rights Agreement to which it is a party, and
compliance by such Purchaser with the terms and provisions hereof and thereof
and the purchase of the Purchased Units by such Purchaser do not and will not
(a) violate any provision of any Law, governmental permit, determination or
award having applicability to such Purchaser or any of its Properties, (b)
conflict with or result in a violation of any provision of the organizational
documents of such Purchaser or (c) require any consent (other than standard
internal consents), approval or notice under or result in a violation or breach

to which such Purchaser is a party or by which such Purchaser or any of its

obligation, except in the case of clauses (a) and (c) where such violation,
default, breach, termination, cancellation, failure to receive consent or
approval, or acceleration with respect to the foregoing provisions of this
Section 4.2 would not, individually or in the aggregate, have a Purchaser
Material Adverse Effect.

 13
 

Section 4.4  Investment.  The
Purchased Units are being acquired for such Purchaser’s own account, or the
accounts of clients for whom such Purchaser exercises discretionary investment
authority, not as a nominee or agent, and with no present intention of
distributing the Purchased Units or any part thereof, and such Purchaser has no
present intention of selling or granting any participation in or otherwise
distributing the same in any transaction in violation of the securities Laws of
the United States of America or any state, without prejudice, however, to such
Purchaser’s right at all times to sell or otherwise dispose of all or any part
of the Purchased Units under a registration statement under the Securities Act
and applicable state securities Laws or under an exemption from such registration
available thereunder (including, if available, Rule 144 promulgated
thereunder).  If such Purchaser should in
the future decide to dispose of any of the Purchased Units, such Purchaser
understands and agrees (a) that it may do so only (i) in compliance with the
Securities Act and applicable state securities Law, as then in effect, or
pursuant to an exemption therefrom or (ii) in the manner contemplated by any
registration statement pursuant to which such securities are being offered, and
(b) that stop-transfer instructions to that effect will be in effect with
respect to such securities. 
Notwithstanding the foregoing, each Purchaser may at any time enter into
one or more total return swaps with respect to such Purchaser’s Purchased Units
with a third party provided that
such transactions are exempt from registration under the Securities Act.

Section 4.5  Nature of Purchaser. 
Such Purchaser represents and warrants to, and covenants and agrees
with, BreitBurn that (a) it is a “qualified institutional buyer” within the
meaning of Rule 144A promulgated by the Securities and Exchange Commission
pursuant to the Securities Act or an “accredited investor” within the meaning
of Rule 501 of Regulation D promulgated by the Commission pursuant to the
Securities Act and (b) by reason of its business and financial experience it
has such knowledge, sophistication and experience in making similar investments
and in business and financial matters generally so as to be capable of
evaluating the merits and risks of the prospective investment in the Purchased
Units, is able to bear the economic risk of such investment and, at the present
time, would be able to afford a complete loss of such investment.

Section 4.6  Receipt of Information; Authorization.  Such Purchaser acknowledges that it has (a)
had access to the BreitBurn SEC Documents, (b) had access to information
regarding the Calumet Acquisition and its potential effect on BreitBurn’s
operations and financial results and (c) been provided a reasonable opportunity
to ask questions of and receive answers from Representatives of BreitBurn
regarding such matters including matters with respect to the Calumet
Acquisition.

Section 4.7  Restricted Securities. 
Such Purchaser understands that the Purchased Units it is purchasing are
characterized as “restricted securities” under the federal securities Laws
inasmuch as they are being acquired from BreitBurn in a transaction not
involving a public offering and that under such Laws and applicable regulations
such securities may be resold without registration under the Securities Act
only in certain limited circumstances. 
In this connection, such Purchaser represents that it is knowledgeable
with respect to Rule 144 of the Commission promulgated under the Securities
Act.

Section 4.8  Certain Fees.  No fees
or commissions will be payable by such Purchaser to brokers, finders or
investment bankers with respect to the sale of any of the Purchased Units or 

 14
 

the consummation of the transactions contemplated by
this Agreement.  BreitBurn will not be
liable for any such fees or commissions.

Section 4.9  Legend.  It is
understood that the certificates evidencing the Purchased Units will initially
bear the following legend:  “These
securities have not been registered under the Securities Act of 1933, as
amended.  They may not be sold, offered
for sale, pledged or hypothecated in the absence of a registration statement in
effect with respect to the securities under such Act or pursuant to an exemption
from registration thereunder and, in the case of a transaction exempt from
registration, unless sold pursuant to Rule 144 under such Act or the issuer has
received documentation reasonably satisfactory to it that such transaction does
not require registration under such Act.”

Section 4.10  No Side Agreements. 
Except for the confidentiality agreements and the Registration Rights
Agreement entered into by and between such Purchaser and BreitBurn, there are
no other agreements by, among or between BreitBurn or its Affiliates, on the
one hand, and such Purchaser or its Affiliates, on the other hand, with respect
to the transactions contemplated hereby nor promises or inducements for future
transactions between or among any of such parties.

ARTICLE V

COVENANTS

Section 5.1  Certain Special Allocations of Book and Taxable Income.  To the extent that the Common Unit Price is
less than the trading price of the Common Units on The Nasdaq Global Market as
of the Closing Date, the General Partner intends to specially allocate items of
book and taxable income to the Purchasers so that their capital accounts in
their Common Units are consistent, on a per-Common Unit basis, with the capital
accounts of the other holders of Common Units (and thus to assure fungibility
of all Common Units).  Such special
allocation will occur upon the earlier to occur of any taxable period of
BreitBurn ending upon, or after, (i) a book-up event or book-down event in
accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f) or a sale of
all or substantially all of the assets of BreitBurn occurring after the date of
the issuance of the Common Units or (ii) the transfer of the Common Units to a
Person that is not an Affiliate of the holder. 
A Purchaser holding a Common Unit shall be required to provide notice to
the General Partner of the transfer of a Common Unit to a Person that is not an
Affiliate of the Purchaser no later than the last Business Day of the calendar
year during which such transfer occurred, unless by virtue of the application
of clause (i) above, the General Partner has determined that the Common Units
are consistent, on a per-Common Unit basis, with the capital accounts of the
other holders of Common Units; provided, that such Purchaser may cure any
failure to provide such notice by providing such notice within 20 days of the
last Business Day of such calendar year; provided, further, that the sole and
exclusive remedy for any Purchaser’s failure to provide any such notice shall
be the enforcement of the remedy of specific performance against such Purchaser
and there will be no monetary damages.

Section 5.2  Subsequent Public Offerings. 
Without the written consent of the holders of a majority of the
Purchased Units, taken as a whole, from the date of this Agreement until the
Lock-Up Date, BreitBurn shall not grant, issue or sell any Common Units, or
other equity or 

 15
 

voting securities of BreitBurn (“Partnership
Securities”), any securities convertible into or exchangeable therefor or
take any other action that may result in the issuance of any of the foregoing,
other than (i) the issuance of the Purchased Units, (ii) the issuance of Awards
(as defined in BreitBurn’s 2006 Long-Term Incentive Plan), the issuance of
Common Units upon the exercise of options to purchase Common Units granted
pursuant to the BreitBurn 2006 Long-Term Incentive Plan and the issuance of
equity-based securities pursuant to a management or employee benefit plan
or in connection with the restructuring of such a plan, (iii) the issuance or
sale of Partnership Securities issued or sold in a registered public offering
to finance future acquisitions that are accretive to distributable cash flow
per Common Unit (or the repayment of indebtedness incurred in connection with
such accretive acquisitions), (iv) the issuance or sale of Partnership Securities
issued, including without limitation to Provident Energy Trust and its
affiliates, as payment of any part of the purchase price for businesses that
are acquired by the Partnership from Provident Energy Trust and its affiliates
or any third party, and (v) the issuance or sale of Partnership Securities
issued or sold through a private placement provided that
(Y) the Purchasers individually are granted the right to participate in such
private placement and to purchase a percentage of the Partnership Securities
sold in such private placement pro rata based
upon their purchase of the Purchased Units sold hereby and (Z) each party
participating in such private placement shall agree that it will not sell any
of its Partnership Securities for a period of 90-days following the closing of
such private placement.  Notwithstanding
the foregoing, BreitBurn shall not, and shall cause its directors, officers and
Affiliates not to, sell, offer for sale or solicit offers to buy any security
(as defined in the Securities Act) that would be integrated with the sale of
the Purchased Units in a manner that would require the registration under the
Securities Act of the sale of the Purchased Units to the Purchasers.

Section 5.3  Purchaser Lock-Up. 
Without the prior written consent of BreitBurn, each Purchaser agrees
that from and after the Closing it will not sell any of its Purchased Units
prior to the Lock-Up Date; provided, however, that each Purchaser may:  (i) enter into one or more total return swaps
or similar transactions at any time with respect to the Purchased Units
purchased by such Purchaser provided that
such transactions are exempt from registration under the Securities Act; or
(ii) transfer its Purchased Units to an Affiliate of such Purchaser or to any
other Purchaser or an Affiliate of such other Purchaser provided
that such Affiliate agrees to the restrictions in this Section 5.3.

Section 5.4   Taking of Necessary Action. 
Each of the Parties hereto shall use its commercially reasonable efforts
promptly to take or cause to be taken all action and promptly to do or cause to
be done all things necessary, proper or advisable under applicable Law and
regulations to consummate and make effective the transactions contemplated by
this Agreement; provided, that nothing contained
herein shall require BreitBurn to consummate the Calumet Acquisition.  Without limiting the foregoing, BreitBurn and
each Purchaser will use its commercially reasonable efforts to make all filings
and obtain all consents of Governmental Authorities that may be necessary or,
in the reasonable opinion of the Purchasers or BreitBurn, as the case may be,
advisable for the consummation of the transactions contemplated by this
Agreement and the other Basic Documents.

Section 5.5  Use of Proceeds.  BreitBurn
shall use the collective proceeds from the sale of the Purchased Units to
finance the Calumet Acquisition.  The
remainder of the proceeds, if any, shall be used to repay indebtedness under
the BreitBurn Credit Facility.

 16

Section 5.6  Tax Information. 
BreitBurn shall cooperate with the Purchasers and provide the Purchasers
with any reasonably requested tax information related to their ownership of the
Purchased Units.

INDEMNIFICATION,
COSTS AND EXPENSES

Section 7.1  Indemnification by BreitBurn.  BreitBurn agrees to indemnify each Purchaser
and its Representatives (collectively, “Purchaser Related Parties”)
from, and hold each of them harmless against, any and all actions, suits,
proceedings (including any investigations, litigation or inquiries), demands
and causes of action, and, in connection therewith, and promptly upon demand,
pay and reimburse each of them for all reasonable costs, losses, liabilities, 

 19
 

damages or expenses of any kind or nature whatsoever,
including, without limitation, the reasonable fees and disbursements of counsel
and all other reasonable expenses incurred in connection with investigating,
defending or preparing to defend any such matter that may be incurred by them
or asserted against or involve any of them as a result of, arising out of or in
any way related to the breach of any of the representations, warranties or
covenants of BreitBurn contained herein; provided that
such claim for indemnification is made prior to the expiration of such
representation or warranty; provided further,
that no Purchaser Related Party shall be entitled to recover special,
consequential (including lost profits) or punitive damages.  Notwithstanding anything to the contrary,
consequential damages shall not be deemed to include diminution in value, which
is specifically included in damages covered by Purchaser Related Parties
indemnification.

Section 7.2  Indemnification by Purchasers.  Each Purchaser agrees, severally and not
jointly, to indemnify BreitBurn, the General Partner, and their respective
Representatives (collectively, “BreitBurn Related Parties”) from, and
hold each of them harmless against, any and all actions, suits, proceedings
(including any investigations, litigation or inquiries), demands and causes of
action, and, in connection therewith, and promptly upon demand, pay or
reimburse each of them for all reasonable costs, losses, liabilities, damages
or expenses of any kind or nature whatsoever, including, without limitation,
the reasonable fees and disbursements of counsel and all other reasonable
expenses incurred in connection with investigating, defending or preparing to
defend any such matter that may be incurred by them or asserted against or
involve any of them as a result of, arising out of or in any way related to the
breach of any of the representations, warranties or covenants of such Purchaser
contained herein; provided that
such claim for indemnification relating to a breach of any representation or
warranty is made prior to the expiration of such representation or warranty;
and provided further, that no
BreitBurn Related Party shall be entitled to recover special, consequential
(including lost profits) or punitive damages. 
Notwithstanding anything to the contrary, consequential damages shall
not be deemed to include diminution in value, which is specifically included in
damages covered by BreitBurn Related Parties indemnification.

Section 7.3  Indemnification Procedure. 
Promptly after any BreitBurn Related Party or Purchaser Related Party
(hereinafter, the “Indemnified Party”) has received notice of any
indemnifiable claim hereunder, or the commencement of any action, suit or
proceeding by a third person that the Indemnified Party believes in good faith
is an indemnifiable claim under this Agreement, the Indemnified Party shall
give the indemnitor hereunder (the “Indemnifying Party”) written notice
of such claim or the commencement of such action, suit or proceeding, but
failure to so notify the Indemnifying Party will not relieve the Indemnifying
Party from any liability it may have to such Indemnified Party hereunder except
to the extent that the Indemnifying Party is materially prejudiced by such
failure.  Such notice shall state the
nature and the basis of such claim to the extent then known.  The Indemnifying Party shall have the right
to defend and settle, at its own expense and by its own counsel who shall be
reasonably acceptable to the Indemnified Party, any such matter as long as the
Indemnifying Party pursues the same diligently and in good faith.  If the Indemnifying Party undertakes to
defend or settle, it shall promptly notify the Indemnified Party of its intention
to do so, and the Indemnified Party shall cooperate with the Indemnifying Party
and its counsel in all commercially reasonable respects in the defense thereof
and the settlement thereof.  Such
cooperation shall include, but shall not be limited to, furnishing the
Indemnifying Party with any books, records and other 

 20
 

information reasonably requested by the Indemnifying
Party and in the Indemnified Party’s possession or control.  Such cooperation of the Indemnified Party
shall be at the cost of the Indemnifying Party. 
After the Indemnifying Party has notified the Indemnified Party of its
intention to undertake to defend or settle any such asserted liability, and for
so long as the Indemnifying Party diligently pursues such defense, the
Indemnifying Party shall not be liable for any additional legal expenses
incurred by the Indemnified Party in connection with any defense or settlement
of such asserted liability; provided, however, that the Indemnified Party shall be entitled (i) at
its expense, to participate in the defense of such asserted liability and the
negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party
has failed to assume the defense or employ counsel reasonably acceptable to the
Indemnified Party or (B) if the defendants in any such action include both the
Indemnified Party and the Indemnifying Party and counsel to the Indemnified
Party shall have concluded that there may be reasonable defenses available to
the Indemnified Party that are different from or in addition to those available
to the Indemnifying Party or if the interests of the Indemnified Party
reasonably may be deemed to conflict with the interests of the Indemnifying
Party, then the Indemnified Party shall have the right to select one separate
counsel and to assume such legal defense and otherwise to participate in the
defense of such action, with the expenses and fees of such separate counsel and
other expenses related to such participation to be reimbursed by the
Indemnifying Party as incurred. 
Notwithstanding any other provision of this Agreement, the Indemnifying
Party shall not settle any indemnified claim without the consent of the
Indemnified Party, unless the settlement thereof imposes no liability or
obligation on, involves no admission of wrongdoing or malfeasance by, and
includes a complete release from liability of, the Indemnified Party.

remedy preclude any other or further exercise thereof or the exercise of any
right, power or remedy.  The remedies
provided for herein are cumulative and are not exclusive of any remedies that
may be available to a Party at law or in equity or otherwise.

(b)           Specific
Waiver.  Except as otherwise provided in
this Agreement or the Registration Rights Agreement, no amendment, waiver,
consent, modification or termination of any provision of any Basic Document

signatories thereto affected by such amendment, waiver, consent, modification
or termination.  Any amendment,
supplement or modification of or to any provision of any Basic Document, any
waiver of any provision of this Agreement or any other Basic Document and any
consent to any departure by BreitBurn or any Purchaser from the terms of any
provision of any Basic Document shall be effective only in the specific
instance and for the specific purpose for which made or given.  Except where notice is specifically required

BreitBurn (i) to any Affiliate of such Purchaser or (ii) in connection with a

Section
8.11  Termination.

(a)           Notwithstanding anything herein to
the contrary, this Agreement may be terminated on or any time prior to the
Closing:

(i)            by

(ii)           by
the written consent of the Purchasers entitled to purchase a majority of the

be untrue in any material respect when made, or (ii) upon a breach in any
material respect of any covenant or agreement on the part of the other set
forth in this Agreement (either (i) or (ii) above being a “Terminating
Breach”); provided, that each Terminating

(b)           Notwithstanding anything herein to

(ii)           if
the Calumet Asset Purchase Agreement shall have been terminated pursuant to its
terms; or

(iii)          if

(c)           In the event of the termination of
this Agreement as provided in Section 8.11(a) or Section 8.11(b), this
Agreement shall forthwith become null and void. 
In the event of such termination, there shall be no liability on the
part of any Party hereto, except with respect to the requirement to comply with
any confidentiality agreement in favor of BreitBurn; provided
that nothing herein shall relieve any Party from any liability or obligation
with respect to any willful breach of this Agreement.

thereby, provided that any request for such
payment is accompanied by a satisfactory written invoice for such
expenses.  If any action at law or equity

prevailing Party shall be entitled to reasonable attorney’s fees, costs and
necessary disbursements in addition to any other relief to which such Party may
be entitled.

Section

limited partner, manager, member, stockholder or Affiliate of any of the

herein shall include the masculine, feminine and neuter gender, and the

ARTICLE II.

SALE AND PURCHASE OF ASSETS

Section 2.1             Sale and Purchase.  On and subject to the terms and conditions of

Section 2.2             Intercompany Accounts.  On or before the Closing Date, Seller shall

ARTICLE III.

PURCHASE PRICE AND PAYMENT

Section 3.1             Purchase Price.  The purchase price for the sale and
conveyance of the Company to Buyer is One Hundred Million Dollars
$100,000,000.00 (the “Purchase Price”), subject to adjustment in
accordance with the terms of this Agreement. 
The “Initial Adjusted Purchase Price” shall be the Purchase Price
as adjusted by the Initial Adjustment Amount determined pursuant to Section
3.3.  The “Adjusted Purchase Price”
shall be the Purchase Price (i) as adjusted in the manner provided in the
immediately preceding sentence,  (ii) as
adjusted downward for the Royalty Accounts and (iii) as adjusted upward by an
amount equal to interest on the Initial Adjusted Purchase Price, as adjusted in
the manner provided in items (i) and (ii) above, from the Effective Time
until the Closing Date at the Agreed Rate.

Section 3.2             Payment.  At the Closing, Buyer shall wire transfer the

41211799007, named “Calumet Florida, L.L.C.”, or such other account or accounts
specified by Seller to Buyer on or prior to the Business Day immediately
preceding the Closing Date.

Section 3.3             Adjustment Period Cash Flow.  (a) 
The Purchase Price shall be increased or decreased, as the case may be,
by an amount equal to the Net Cash Flow with respect to the Assets for the time
period (the “Adjustment Period”) beginning at the Effective Time and
ending at 7:00 a.m. (local time) on the Closing Date.  Seller shall deliver to Buyer on or prior to
the calendar day preceding the Closing Date a statement (the “Adjustment
Statement”) setting forth Seller’s preliminary determination (the “Initial
Adjustment Amount”) of the Net Cash Flow. 
If the Initial Adjustment Amount shown on the Adjustment Statement is a
positive number, then the Purchase Price shall be increased by such
amount.  If the Initial Adjustment Amount
shown on the Adjustment Statement is a negative number, then the Purchase Price
shall be decreased by such amount.

(b)           The Adjustment Statement shall be
based upon actual information available to Seller at the time of its
preparation and upon Seller’s good faith estimates and assumptions.  There shall be attached to the Adjustment
Statement such supporting 

 2
 

documentation and
other data as is reasonably necessary to provide a basis for the Net Cash Flow
shown therein.

(c)           The “Net Cash Flow” shall be
the algebraic sum of (i) a positive amount equal to the sum of (A) the
aggregate amount incurred by Seller as costs of maintenance and operation of
the Pipeline System Assets incurred with respect to the Adjustment Period and
(B) the aggregate amount incurred by Seller as Seller’s share of the costs of
exploration, development, maintenance, operation, abandonment and production of
the E & P Assets incurred with respect to the Adjustment Period, which
costs referred to in clauses (A) and (B) above shall include, but shall not be
limited to, royalties, overriding royalties, net profit interests and other
similar burdens on production, general, administrative and indirect costs and
fees in a total amount not to exceed Sixty Thousand Dollars ($60,000) per month
(prorated on a daily basis for partial months), Taxes (other than income Taxes,
franchise Taxes and taxes similar to income or franchise Taxes), the cost of
maintaining leaseholds or other interests included in the Assets, the cost of
extension or renewal of any interest included in the Assets, the cost of
treating, processing, storing, compressing, transporting, selling, marketing
and otherwise handling and dealing with hydrocarbon production with respect to
the Assets, the cost of any exploration or development activities on the Assets
performed in accordance with Article VIII, and costs of insurance coverage
(including prepayments of any costs in accordance with Article VIII), (ii) a
negative amount equal to sum of (A) the aggregate gross revenue received by
Seller from the operation of the Pipeline System Assets during the Adjustment
Period and (B) the aggregate gross proceeds received by Seller from the sale of
hydrocarbons produced from or attributable to the E&P Assets during the
Adjustment Period or from the sale, salvage or other disposition of any Assets
during the Adjustment Period (excluding any payments accounted for under clause
(ii) of Section 3.1), and (iii) a negative amount equal to the aggregate amount
of any costs incurred under clause (i) above and reimbursed to Seller by any third
party (unless such reimbursement is accounted for under clause (ii) above).

Section 3.4             Post Closing Review.  After the Closing, Seller shall review the
Adjustment Statement and determine the actual Net Cash Flow and, if applicable,
the correct interest calculation based on the Adjusted Purchase Price rather
than the Initial Adjusted Purchase Price. 
On or prior to the 60th day after the Closing Date, Seller shall present
Buyer with a statement of the actual Net Cash Flow and such supporting
documentation as is reasonably necessary to support the Net Cash Flow shown
therein (the “Final Adjustment Statement”).  To the extent reasonably necessary to Seller,
Buyer will give personnel, accountants and representatives of Seller reasonable
access to the Assets and Buyer’s premises and to its books and records for
purposes of preparing the Final Adjustment Statement and will cause appropriate
personnel of Buyer to assist Seller and Seller’s personnel, accountants and
representatives, with no charge to Seller for such assistance, in the
preparation of the Final Adjustment Statement. 
Seller will give personnel, accountants and representatives of Buyer
reasonable access to Seller’s premises and to its books and records for
purposes of reviewing the calculation of Net Cash Flow and will cause
appropriate personnel of Seller to assist Buyer and Buyer’s personnel,
accountants and representatives, with no charge to Buyer for such assistance,
in verification of such calculation.  The
Final Adjustment Statement shall become final and binding on Seller and Buyer
as to the Net Cash Flow 30 days following the date the Final Adjustment
Statement is received by Buyer, except to the extent that prior to the
expiration of 

 3
 

such 30-day period Buyer shall deliver to
Seller one or more notices, as hereinafter required, of its disagreement with
the contents of the Final Adjustment Statement. 
Such notices shall be in writing and set forth all of Buyer’s
disagreements with respect to any portion of the Final Adjustment Statement,
together with Buyer’s proposed changes thereto, and shall include an
explanation in reasonable detail of, and such supporting documentation as is
reasonably necessary to support, such changes. 
Any disagreements with or changes to the Final Adjustment Statement not
included in such notices shall be waived by Buyer.  If Buyer has timely delivered one or more
notices of disagreement to Seller in the manner required above, then, upon
written agreement between Buyer and Seller resolving all disagreements of Buyer
set forth in such notices, the Final Adjustment Statement (including any
revisions thereto as are so agreed) will become final and binding on Buyer and
Seller as to the Net Cash Flow.  If the
Final Adjustment Statement has not become final and binding by the 120th day
following the Closing Date, then Buyer or Seller may submit any unresolved
disagreements of Buyer set forth in the aforesaid notices to Ernst & Young,
Houston, Texas for final and binding determination.  The fees and expenses of said accounting firm
in making such determination shall be shared equally by Buyer and Seller.  Upon resolution of such unresolved
disagreements of Buyer, the Final Adjustment Statement (including any revisions
thereto as are so resolved or agreed), shall be conclusive, final and binding
on Buyer and Seller as to the Net Cash Flow. 
If the final amount of Net Cash Flow is more or less than the Initial
Adjustment Amount, the Initial Adjusted Purchase Price shall be redetermined
under Section 3.1 using such final amount of Net Cash Flow.  If such redetermination under Section 3.1
results in a reduction in the Initial Adjusted Purchase Price, Seller shall pay
Buyer the amount of such reduction.  If such
redetermination results in an increase in the Initial Adjusted Purchase Price,
Buyer shall pay Seller the amount of such increase.  Within three (3) Business Days after the
Final Adjustment Statement (as so resolved or agreed) becomes final and
binding, Seller or Buyer, as appropriate, shall pay to the other party the
amount of such increase or reduction, if any, in the Initial Adjusted Purchase
Price, together with interest on the amount of such increase or reduction from
the Closing Date until paid at the Agreed Rate. 
Except for specific costs which are expressly set forth and accounted
for in the final and binding Final Adjustment Statement, neither the Final
Adjustment Statement nor this Section 3.4 shall operate to waive, release or
impair the indemnity and hold harmless obligations of Buyer under Sections 5.1,
and 13.1 or Seller under 13.2.

COVENANTS OF SELLER AND BUYER

of Business Pending Closing.  Subject
to Section 8.2 and the constraints of applicable operating agreements and other
existing agreements, from the date hereof through the Closing, except as
disclosed in Schedule 8.1
or as otherwise consented to or approved by Buyer (which consent or approval
shall not be unreasonably withheld or delayed), Seller covenants and agrees
that:

(a)           Changes
in Business.  Seller shall not:

(1)           make any material change in the
conduct of its business or operations with respect to the Assets;

(2)           except in the ordinary course of
business and consistent with past practices, enter into, assign, terminate or
amend, in any material respect, any contract or agreement required to be
disclosed pursuant to Section 4.1(j);

(3)           sell, lease or otherwise dispose of

disposed of in the ordinary course of business, (ii) incident to the exploration,
operation or development of the Assets in accordance with this Section 8.1 or
Section 8.2, (iii) personal property or equipment which is replaced with
personal property or equipment of comparable or better value and utility in
connection with the maintenance, repair and operation of the Assets, and (iv)

or

(4)           materially increase or change the
wages, salaries and benefits payable to the Company Employees.

(b)           Liens.  Seller shall not create any express lien or
security interest on any Assets, except to the extent (i) required or permitted
incident to the exploration, operation or development of the Assets pursuant to
this Section 8.1 or Section 8.2, (ii) required or evidenced by

 12
 

the Hydrocarbon Interests, joint operating agreements
or unitization or pooling agreements relating to the Subject Interests, or
(iii) required or evidenced by any contract or agreement required to be
disclosed pursuant to Section 4.1(j).

(c)           Operation
of Assets.  Seller shall:

(1)           cause the Assets to be maintained and
operated (and the production attributable thereto marketed, sold, exchanged,
processed and otherwise handled) in the ordinary course of business in
accordance with Seller’s past practices (including the repair or replacement of
damaged, destroyed, obsolete, depreciated, non-working or non-economical items
of equipment or other personal property without regard to the limitation of
Section 8.1(c)(2) below), maintain insurance now in force with respect to the
Assets, and pay or cause to be paid all costs and expenses in connection
therewith promptly when due;

(2)           not commit to participate in the
drilling of any new well or other new operations on the E & P Assets the
projected cost of which (net to Seller’s interest and without consideration of
any cost overruns) is in excess of $25,000 in any single instance, without the
advance written consent of Buyer, which consent or non-consent must be given by
Buyer within the lesser of (x) ten (10) days of Buyer’s receipt of the notice
from Seller or (y) one-half (1⁄2) of the applicable notice period within which
Seller is contractually obligated to respond to third parties to avoid a deemed
election by Seller regarding such operation, as specified in Seller’s notice to
Buyer requesting such consent; provided that, failure by Buyer to respond
within the aforesaid applicable period shall constitute Buyer’s consent to
Seller’s participation in such well or other operation;

(3)           maintain and keep the Assets in full
force and effect, except where such failure is due to (i) the failure to pay a
delay rental, royalty, shut in royalty or other payment by mistake or oversight
(including Seller’s negligence) unless caused by Seller’s gross negligence or
willful misconduct, or (ii) the failure to participate in an operation which
Buyer does not timely approve; and

(4)           use Seller’s reasonable best efforts
to maintain its relationships with suppliers, customers and others having
material business relations with Seller with respect to the Assets so that they
will be preserved for the Company on and after the Closing Date.

(d)           Contracts
and Agreements.  Seller shall not:

(1)           grant or create any Preference Right
or Transfer Requirement with respect to the Assets except (i) in connection
with the performance by Seller of an obligation or agreement existing on the
Effective Time or pursuant to this Agreement or (ii) in connection with the
renewal or extension of Assets after the Effective Time if granting or creating
such Preference Right or Transfer Requirement is a condition of such renewal or
extension;

 13
 

(2)           enter into any oil, gas or other
hydrocarbon sales, exchange, gathering, processing or transportation contract
with respect to the Assets having a term in excess of one (1) year which is not
terminable without penalty on notice of ninety (90) days or less;

(3)           voluntarily relinquish Seller’s
position as operator with respect to any of the Assets; or

(4)           enter into, terminate early, amend or
default under any Derivative without Buyer’s prior written consent.

Section 8.2             Qualifications
on Conduct.

(a)           Emergencies;
Legal Requirements.  Seller may take
(or not take, as the case may be) any of the actions mentioned in Section 8.1
if reasonably necessary under emergency circumstances (or if required or
prohibited, as the case may be, pursuant to Law) and provided Buyer is notified
as soon thereafter as practicable.

(b)           Non-Operated
Properties.  If Seller is not the
operator of a particular portion of the Assets, the obligations of Seller in
Section 8.1 with respect to such portion of the Assets, which have reference to
operations or activities that pursuant to existing contracts are carried out or
performed by the operator, shall be construed to require only that Seller use
its reasonable best efforts (without being obligated to incur any expense or
institute any cause of action) to cause the operator of such portion of the
Assets to take such actions or render such performance within the constraints
of the applicable operating agreements and other applicable agreements.

(c)           Certain
Operations.

(1)           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 Property Subdivision constituting part of the E & P Assets which
may otherwise be required by Section 8.1, Seller shall give Buyer written
notice thereof at least fifteen (15) days prior to the date such rental or
other payment is due or, in the case of an operation, promptly after Seller
receives notice of such proposed operation from the operator of such property
(or if Seller is the operator, at the same time Seller gives or is required to
give notice of such proposed operation to the non-operators of such
property).  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, (a) the written election and agreement of Buyer
(i) to require Seller to take such action and (ii) to pay all costs and
expenses of Seller with respect to such lease rental or other payment or such
operation and (b) the funds necessary for such payment or operation as
contained in the applicable AFE therefor or estimated by Seller.  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 operator of the property involved
recommends that such action not be taken. 
If Buyer advances any funds pursuant to this Section 8.2(c) with respect
to a

 14
 

particular portion of the E & P Assets, such
portion of the Assets is excluded from the Assets pursuant to the terms hereof
or Closing does not occur, and such funds are not reimbursed to Buyer within
thirty (30) days after the earlier of Closing or termination of this Agreement,
then with respect to such particular portion of the E & P Assets, (i) Buyer
shall own and be entitled to any interest of Seller that would have lapsed but
for such payment or (ii) in the case of operations, Buyer shall be entitled to
receive the penalty, if any, that Seller, as nonconsenting party, would have
suffered under the applicable operating or other agreement with respect to such
operations as if Buyer were a consenting party thereunder; in each case,
subject to and after deduction of any damages or other relief to which Seller
may be entitled with respect to any breach by Buyer of this Agreement.

(2)           If a notice delivered to Buyer
pursuant to Section 8.1(c)(2) sets forth a recommendation that Seller
participate in an operation or capital expenditure the failure in which to participate
will cause the forfeiture of all or any portion of a Subject Interest (or any
interest in production attributable thereto) and Buyer timely notifies Seller
that it does not desire Seller to participate in same, then, on or before the
Closing, Seller may elect to exclude from the Assets and reserve to Seller the
Subject Interest (or the interest therein or interest in production therefrom)
that would be so forfeited, together with a pro rata share of all Incidental
Rights, oil, gas and other hydrocarbons and other assets attributable or
appurtenant thereto (but only to the extent such Incidental Rights, oil, gas
and other hydrocarbons and other assets are practicably severable from the
Assets without adversely impacting in any material respect the value or
operations of the remaining Assets).  If
such Incidental Rights, oil, gas and other hydrocarbons and other assets are
not so practicably severable from the Assets, Buyer shall execute and deliver
to Seller at Closing a perpetual use agreement on commercially reasonable terms
which grants to Seller and its successors and assigns the practical benefits
Seller would have received from such Incidental Rights, oil, gas and other
hydrocarbons and other assets had they been so excluded and reserved to Seller.  No reduction in the Purchase Price shall be
made on account of any exclusion, reservation, use agreement or other matter
provided for in this Section 8.2(c)(2).

Section 8.3             Assignment
of Membership Interests.  Upon the
terms and subject to the conditions of this Agreement, at or prior to the
Closing, Seller and Buyer shall execute and deliver or cause the execution and
delivery of the Assignment of Membership Interests, in substantially the form
attached hereto as Exhibit 8.3
(the “Assignment”).  To the extent
any liens or security interests securing indebtedness encumber any of the
Membership Interests, Seller shall cause such liens and security interests to
be terminated and released concurrently with the Closing.

Section 8.4             Public
Announcements.  Prior to the Closing
Date, without the prior written approval of the other party hereto, which
approval shall not be unreasonably withheld, no party hereto will issue, or
permit any agent or Affiliate of it to issue, any press releases or otherwise
make, or cause any agent or Affiliate of it to make, any public statements with
respect to this Agreement and the transactions contemplated hereby, except
where such release or statement is deemed in good faith by the releasing party
to be required by Law or under the rules

 15
 

and regulations of the NASDAQ or New York stock
exchanges (or other public stock exchange of similar reputation and standing)
on which the shares of such party or any of its Affiliates are listed.  In each case to which such exception applies,
the releasing party will use its reasonable best efforts to provide a copy of
such release or statement to the other parties prior to releasing or making the
same.  Seller approves Buyer’s issuance
of a press release in the form of Exhibit 8.4
immediately after the execution of this Agreement by both parties.

Section 8.5             Amendment
of Schedules.  As of the Closing
Date, all Schedules hereto shall be deemed amended and supplemented to include
reference to any matter (a) relating to Seller or the Assets which first arises
or occurs after the date of execution of this Agreement and does not result
from a breach by Seller of Section 8.1, (b) which results in an adjustment to
the Purchase Price pursuant to Section 3.1, or (c) which relates to a property
excluded from the Assets pursuant to Section 8.2(c)(2).

Section 8.6             Parties’
Efforts and Further Assurances. 
Buyer covenants and agrees to take all actions which are necessary for
it to be in compliance with its warranties and representations contained in
Sections 4.2(h), 4.2(i) and 4.2(j) on the Closing Date.  Each of the parties agrees to use
commercially reasonable efforts (and to cause its Affiliates to use
commercially reasonable efforts) to refrain from taking any action within its
control which would cause a breach of any of its representations and warranties
contained in Article IV or which would prevent it from delivering to the other
parties the certificate which it is required to deliver pursuant to Section
9.1(b) or 9.2(b), as the case may be. 
Seller and Buyer each agree that from time to time after the Closing
Date, each of them will execute and deliver or cause their respective
Affiliates to execute and deliver such further instruments, and take (or cause
their respective Affiliates to take) such other action, as may be reasonably
necessary to carry out the purposes and intents of this Agreement.

Section 8.7             Asset
Records.  Within a reasonable period
of time following the end of the term of the Transition Agreement, Seller shall
make all Asset Records available for delivery to Buyer at Seller’s offices in
Houston, Texas or at the locations of the Assets in the case of Asset Records
maintained at such locations.  Buyer
agrees to maintain all Asset Records until the fifth anniversary of the Closing
Date (or for such longer period of time as Seller shall advise Buyer is
necessary in order to have the Asset Records available with respect to open
years for Tax audit purposes), or, if any of the Asset Records pertain to any
claim or dispute pending on the fifth anniversary of the Closing Date, Buyer
shall maintain any of the Asset Records designated by Seller until such claim
or dispute is finally resolved and the time for all appeals has been
exhausted.  Buyer shall provide Seller
and its representatives reasonable access to and the right to copy the Asset
Records for the purposes of (i) preparing and delivering any accounting
provided for under this Agreement and adjusting, prorating and settling the
charges and credits provided for in this Agreement, (ii) complying with any Law
affecting Seller’s interest in the Assets prior to the Closing Date, (iii)
conducting and preparing any audit of the books and records of any third party
relating to Seller’s interest in the Assets prior to the Closing Date, or
responding to any audit conducted or prepared by such third parties, (iv)
preparing Tax returns, (v) responding to or disputing any Tax audit or (vi)
asserting, defending or otherwise dealing with any claim or dispute under this
Agreement or with respect to the Assets. 
In no event shall Buyer or any of its Affiliates destroy any Asset
Records without giving Seller sixty (60) days’

 16
 

advance written notice thereof and the opportunity, at
Seller’s expense, to obtain such Asset Records prior to their destruction.

Section 8.8             Recording.  Immediately following the Closing, Buyer, at
its cost and expense, shall record the Conveyance and all other instruments of
assignment in the appropriate governmental offices of the jurisdictions in
which the Assets are located.  Promptly following
such recording, Buyer shall advise Seller in writing of the pertinent recording
data.

Section 8.9             Casualty
and Condemnation.  If after the
Effective Time and prior to the Closing any part of the Assets shall be
destroyed or damaged by fire or other casualty or if any part of the Assets
shall be taken in condemnation or under the right of eminent domain or if
proceedings for such purposes shall be pending or threatened, this Agreement
shall remain in full force and effect notwithstanding any such destruction,
taking or proceeding or the threat thereof. 
To the extent insurance proceeds, condemnation awards or other payments
are not committed, used or applied by Seller prior to the Closing Date to
repair, restore or replace such damaged, destroyed or taken Assets, Seller
shall at the Closing (i) assign to the Company Seller’s right to receive all
insurance or condemnation proceeds, awards or payments owed to Seller by reason
of such destruction or taking, less any reasonable costs and expenses incurred
by Seller in collecting same or in connection with such proceedings or the
threat thereof, and (ii) pay to the Company all insurance or condemnation
proceeds, awards or payments theretofore paid to Seller by reason of such
destruction or taking, less any reasonable costs and expenses incurred by
Seller in collecting same or in connection with such proceedings or the threat
thereof.  Notwithstanding the foregoing,
any insurance or condemnation proceeds, awards or payments (or any rights
thereto) by reason of such destruction or taking which are held by or owed to
Seller for the account or benefit of any third party joint interest owners
shall not be paid or assigned by Seller to the Company pursuant to this Section
and shall instead be transferred to the successor operator or other Person
responsible therefor pursuant to the terms of the applicable operating or other
agreement.

Section 8.10           Transition
Agreement.  At Closing, Seller and
the Company shall execute and deliver a Transition Services Agreement (the “Transition
Agreement”) providing for the performance by Seller or its Affiliates of
certain transition services with respect to the operation of the Assets after
Closing in substantially the form attached hereto as Exhibit 8.10.

Section 8.11           Employees.

(a)           Company
Employees.  “Company Employees”
shall mean the employees of Seller listed on Schedule 8.11(a) attached hereto.  Effective as of 12:01 a.m. on the day
immediately following the date of termination of the Transition Agreement (the Transition
Termination Date”), the employment of the Company Employees with Seller
shall terminate. Buyer or another member of the controlled group (within the
meaning of Section 414(b), (c), (m) or (o) of the Code) of which Buyer is a
member (the “Buyer Controlled Group”) shall have the right commencing on
the Transition Termination Date to make a comparable offer of employment to any
or all of the Company Employees in its sole discretion.  A comparable offer of employment to a Company
Employee shall be an offer of employment (a) at the Company Employee’s current
base salary with Seller as of the date of this Agreement (as set out on Schedule 8.11(a)); (b) with
substantially the

 17
 

same duties and responsibilities; (c) at the same
location (or such other worksite as the Company Employee may agree to), and (d)
made only after prior written notice to Seller of the name of each such Company
Employee and the terms of such offer.

(b)           Continuing
Employees.  Company Employees who
accept an offer of employment and become employed by a member of the Buyer
Controlled Group on such day following the Transition Termination Date, are
hereinafter referred to as the “Continuing Employees.”  The effective date of employment of the
Continuing Employee with the employing member of the Buyer Controlled Group
shall be such day following the Transition Termination Date.  Nothing contained herein shall confer upon
any Continuing Employee any right with respect to continuance of employment by
Buyer or any other member of the Buyer Controlled Group, nor shall anything
herein interfere in any way with the right of an employing member of the Buyer

entitled to be indemnified under Section 5.1, 13.1 or 13.2 is herein referred
to as an “Indemnified Person” and the party which is obligated to
indemnify an Indemnified Person under Section 5.1, 13.1 or 13.2 is herein
referred to as the “Indemnifying Party” with respect to the matter for
which it is obligated to indemnify such Indemnified Person.  All claims for indemnification under Sections
5.1, 13.1 and 13.2 shall be asserted and resolved as follows:

(a)           If a third party claim for which an
Indemnified Person is entitled to indemnity under Sections 5.1, 13.1 and/or
13.2 (an “Indemnified Claim”) is made against an Indemnified Person, and
if Buyer or Seller intends to seek indemnity with respect thereto by or from an
Indemnifying Party pursuant to Sections 5.1, 13.1 and/or 13.2, then the party
electing to seek indemnity on behalf of such Indemnified Person shall promptly
transmit to the Indemnifying Party a written notice (“Claim Notice”) (i)
notifying such Indemnifying Party of such Indemnified Claim and requesting
indemnity on behalf of such Indemnified Person with respect to such Indemnified
Claim under Sections 5.1, 13.1 and/or 13.2, as the case may be,
(ii) setting forth the full name, address for all notices and the
authorized representatives of such Indemnified Person with respect to such
Indemnified Claim, and (iii) describing in reasonable detail the nature of the
Indemnified Claim, including a copy of all papers served with respect to such
Indemnified Claim (if any) and the basis of such request for indemnification under
Sections 5.1, 13.1 and/or 13.2, as the case may be.  Failure to provide such Claim Notice promptly
shall not affect the right of the Indemnified Person to indemnification
hereunder except to the extent the Indemnifying Party is prejudiced thereby;
provided that, the Indemnifying Party shall not be obligated to defend,
indemnify or otherwise hold harmless an Indemnified Person with respect to a
third party claim until a Claim Notice meeting the foregoing requirements is
furnished to the Indemnifying Party by the party seeking indemnity
hereunder.  Within 30 days after receipt
of any Claim Notice (the “Election Period”), the Indemnifying Party
shall notify the party who sent the Claim Notice (A) whether the Indemnifying
Party disputes its potential liability to indemnify the Indemnified Person
under Sections 5.1, 13.1 and/or 13.2, as the case may be, with respect to such
third party claim and (B) whether the Indemnifying Party desires to defend the
Indemnified Person against such third party claim; provided that, if the
Indemnifying Party fails to so notify the Indemnified Person during the
Election Period, the Indemnifying Party shall be deemed to have elected to
dispute such liability and not to defend against such third party claim.

(b)           If the Indemnifying Party notifies
the party who sent the Claim Notice within the Election Period that the
Indemnifying Party (i) does not dispute its liability to indemnify the
Indemnified Person under Sections 5.1, 13.1 and/or 13.2, as the case may be (or
reserves the right to dispute whether such claim is an Indemnified Claim under
Sections 5.1, 13.1 and/or 13.2) and (ii) elects to assume the defense of such
Indemnified Person with respect to such third party claim, then the
Indemnifying Party shall have the right to defend, at its sole cost and
expense, such third party claim by all appropriate proceedings, which
proceedings shall be prosecuted diligently by the Indemnifying Party to a final
conclusion or settled at the discretion of the Indemnifying Party in accordance
with this Section 13.3(b).  If an
Indemnifying Party elects pursuant to the foregoing to assume the defense of an
Indemnified Person with respect to a third party claim which is subsequently
determined not to be an Indemnified Claim, the Indemnifying Party shall not be
entitled to recover from the Indemnified Person the costs and expenses incurred
by the Indemnifying Party in providing such defense.  The Indemnifying Party 

 28
 

shall have full
control of such defense and proceedings, including any compromise or settlement
thereof; provided that the Indemnifying Party shall not enter into any
settlement agreement (or settle or compromise any such third party claim in a
manner) which provides for or results in any payment by or liability of the
Indemnified Person of or for any damages or other amount, any lien, charge or
encumbrance on any property of the Indemnified Person, any finding of
responsibility or liability on the part of the Indemnified Person or any
sanction or restriction upon the conduct of any business by the Indemnified
Person without the Indemnified Person’s express written consent, which consent
shall not be unreasonably withheld.  The
Indemnified Person is hereby authorized, at the sole cost and expense of the
Indemnifying Party (but only if the Indemnified Person is actually entitled to
indemnification hereunder), to file, during the Election Period, any motion,
answer or other pleadings which the Indemnified Person shall deem necessary or
appropriate to protect its interests or those of the Indemnifying Party and not
reasonably expected to be prejudicial to the Indemnifying Party.  If requested by the Indemnifying Party, the
Indemnified Person agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and its counsel in contesting
any such third party claim which the Indemnifying Party elects to contest,
including the making of any related counterclaim or cross-complaint against any
Person (other than a Buyer Indemnified Person, if the Indemnified Person is a
Buyer Indemnified Person, or a Seller Indemnified Person, if the Indemnified
Person is a Seller Indemnified Person). 
The Indemnified Person may participate in, but not control, any defense
or settlement of any third party claim controlled by the Indemnifying Party
pursuant to this Section 13.3(b), and the Indemnified Person shall bear its own
costs and expenses with respect to such participation.  The prosecution of the defense of a third
party claim with reasonable diligence shall include the taking of such action
(including the posting of a bond, deposit or other security) as may be
necessary to prevent any action to foreclose a lien against or attachment of
the property of the Indemnified Person for payment of such third party claim.

(c)           If the Indemnifying Party (i) fails
to notify the party who sent the Claim Notice within the Election Period that
the Indemnifying Party elects to defend the Indemnified Person pursuant to
Section 13.3(b) or (ii) elects to defend the Indemnified Person pursuant to Section
13.3(b) but fails to prosecute the defense of (or to settle) the third party
claim with reasonable diligence, then the Indemnified Person shall have the
right to defend, at the sole cost and expense of the Indemnifying Party (but
only if the Indemnified Person is actually entitled to indemnification
hereunder), the third party claim by all appropriate proceedings, which
proceedings shall be promptly and vigorously prosecuted by the Indemnified
Person to a final conclusion or settled. 
The Indemnified Person shall have full control of such defense and
proceedings; provided, however, that the Indemnified Person may not enter into
any compromise or settlement of such third party claim, without the
Indemnifying Party’s express written consent, which shall not be unreasonably
withheld.  The Indemnifying Party may
participate in, but not control, any defense or settlement controlled by the
Indemnified Person pursuant to this Section 13.3(c), and the Indemnifying Party
shall bear its own costs and expenses with respect to such participation.

(d)           If the Indemnifying Party elects not
to assume the defense of a third party claim, or elects to assume the defense
of a third party claim, but reserves the right to dispute whether such claim is
an Indemnified Claim under Sections 5.1, 13.1 and/or 13.2, as the case 

 29
 

may be, the
determination of whether the Indemnified Person is entitled to indemnification
hereunder shall be resolved pursuant to arbitration as provided in Section
15.10.

(e)           If an Indemnified Person is entitled
to indemnity under Sections 5.1, 13.1 and/or 13.2 for a claim or other matter
which does not involve a third party claim, and if Buyer or Seller intends to
seek indemnity on behalf of an Indemnified Person with respect thereto by or
from an Indemnifying Party pursuant to Sections 5.1, 13.1 and/or 13.2, then the
party electing to seek indemnity on behalf of an Indemnified Person shall
promptly transmit to the Indemnifying Party a written notice describing in
reasonable detail the nature of such claim or other matter, the Indemnified
Person’s best estimate of the amount of damages attributable to such claim or
other matter and the basis for the Indemnified Person’s entitlement to
indemnification under Sections 5.1, 13.1 and/or 13.2, as the case may be.  If the Indemnifying Party does not notify the
party who sent such notice within 30 days from its receipt of such notice that
the Indemnifying Party does not dispute such claim for indemnity, the
Indemnifying Party shall be deemed to have disputed such claim.  If the Indemnifying Party has disputed such
claim, such dispute shall be resolved pursuant to arbitration as provided in
Section 15.10.

(f)            To the extent any claim, action,
suit or proceeding includes one or more Indemnified Claims with respect to an
Indemnified Person and one or more third party claims which are not Indemnified
Claims with respect to such Indemnified Person, any such non-Indemnified Claim
insofar as it is with respect to such Indemnified Person shall not be covered
by the indemnity in Sections 5.1, 13.1 and 13.2, the Indemnifying Party shall
not be obligated to undertake, conduct and control the defense or settlement of
such non-Indemnified Claim insofar as it is with respect to such Indemnified
Person, and such Indemnified Person shall be responsible for its own defense
and settlement of such non-Indemnified Claim. 
The seeking by a party of indemnity hereunder on behalf of any
Indemnified Person with respect to any third party claim or other claim or
matter shall not prevent such party from then or thereafter also seeking
indemnity hereunder on behalf of any other Indemnified Person with respect to
such third party claim or other claim or matter and shall not prevent the other
party from seeking indemnity hereunder on behalf of any Indemnified Person with
respect to the same third party claim or other claim or matter.

(g)           The term “Indemnified Transfer Tax
Claim” as used herein means a claim by or on behalf of any Governmental
Authority in the State of Florida for any Tax or fee described in the first
sentence of Section 15.4. 
Notwithstanding the provisions of Sections 13.3(b) and (c), with respect
to any Indemnified Transfer Tax Claim, any Seller Indemnified Person may enter
into any compromise or settlement of such Indemnified Transfer Tax Claim, in
such Seller Indemnified Person’s sole discretion, without the Indemnifying
Party’s prior consent, and no Seller Indemnified Person shall be required to
make any related counterclaim or cross-complaint against any Person in
connection with such Indemnified Transfer Tax Claim or otherwise cooperate with
the Indemnifying Party or its counsel in contesting any such Indemnified
Transfer Tax Claim.

Section 13.4           Seller’s General Liability
Limitation.  (a) Notwithstanding
anything herein provided to the contrary, Seller shall have no liability to
Buyer or any of the other Buyer Indemnified Persons pursuant to Section 13.2 or
for any breach by Seller of any representation or 

 30
 

warranty made by Seller in clauses (a) and
(d) through (u) of Section 4.1 to the extent that the aggregate amount of all
Covered Liabilities attributable to all such liabilities or breaches exceeds an
amount equal to fifty percent (50%) of the Adjusted Purchase Price.

(b)           Notwithstanding
anything herein provided to the contrary but without in any way affecting the
obligations of a Buyer Indemnified Person to notify Seller of a third party
claim pursuant to Section 13.3, Seller shall not have any liability to a Buyer
Indemnified Person with respect to any Covered Liability pursuant to Section
13.2 unless and until Buyer has used reasonable efforts to enforce its rights
and remedies, if any, with respect to such Covered Liability against any other
Person pursuant to (i) any insurance maintained for the joint account under any
operating agreement with respect to the Assets and (ii) any other agreements
for insurance, indemnification, guarantee or similar assurances which may be
included in the Assets.

Section 13.5           Materiality Exclusion.  Notwithstanding anything to the contrary
contained in this Agreement, for purposes of determining if there has been a
breach of any representation or warranty hereunder by Seller or Buyer and the
amount of the Covered Liabilities in respect thereof, the representations and
warranties of Seller and Buyer shall, for purposes of this Article XIII, be
read without giving effect to any materiality, Material Adverse Effect or
qualification with a similar meaning in such representation or warranty.

ARTICLE XIV.

TERMINATION; REMEDIES

Section 14.1           Termination.

(a)   Termination of Agreement. 
This Agreement and the transactions contemplated hereby may be
terminated at any time prior to the Closing:

(1)       By
the mutual consent of Seller and Buyer; or

(2)       If
the Closing has not occurred by the close of business on the Closing Date, then
(i) by Seller if any condition specified in Section 9.1 has not been satisfied
on or before such close of business, and shall not theretofore have been waived
by Seller, or (ii) by Buyer if any condition specified in Section 9.2 has not
been satisfied on or before such close of business, and shall not theretofore
have been waived by Buyer; provided, in each case, that the failure to
consummate the transactions contemplated hereby on or before such date did not
result from the failure by the party or parties seeking termination of this
Agreement to fulfill any undertaking or commitment provided for herein on the
part of such party or parties that is required to be fulfilled on or prior to
Closing.

(b)   Effect of Termination. 
In the event of termination of this Agreement by Seller, on the one
hand, or Buyer, on the other hand, pursuant to Section 14.1(a), written notice
thereof shall forthwith be given by the terminating party or parties to the
other party or parties hereto, and this Agreement shall thereupon terminate;
provided, however, that following such termination Buyer will continue to be
bound by its obligations set forth in Sections 5.1 and 5.2.  If this Agreement is terminated as provided
herein all filings, applications and other submissions made 

 31
 

to any Governmental Authority shall, to the
extent practicable, be withdrawn from the Governmental Authority to which they
were made.

Section 14.2           Remedies.

(a)   Seller’s Remedies. 
Notwithstanding anything herein provided to the contrary, if this
Agreement is not terminated by Buyer pursuant to Section 14.1(a) and Buyer
fails to satisfy on or prior to the Closing Date the conditions to Closing or
the Closing obligations, as the case may be, set forth in Sections 9.1(a),
9.1(b), 9.1(c), 9.1(e) or 10.3, Seller, at its sole option, may (i) enforce
specific performance of this Agreement or (ii) terminate this Agreement and,
without waiving or releasing Buyer’s obligations under Sections 5.1 and 5.2,
recover from Buyer the sum of $50,000,000.00 as liquidated damages.  Such remedies shall be Seller’s sole and
exclusive remedies for such failure, all other remedies being expressly waived
by Seller.  Seller and Buyer agree upon
such amount as liquidated damages due to the difficulty and inconvenience of
measuring actual damages and the uncertainty thereof, and Seller and Buyer
agree that such amount is a reasonable estimate of Seller’s loss in the event
of any such failure by Buyer.  Without
waiving or releasing Buyer from any of its other representations, warranties,
covenants and agreements contained herein, specific performance with respect to
clause (ii)(a) of Section 10.3 shall not require Buyer to make a false
statement in the officer’s certificate of Buyer.

(b)   Buyer’s Remedies. 
Notwithstanding anything herein provided to the contrary, if this
Agreement is not terminated by Seller pursuant to Section 14.1(a) and Seller
fails to satisfy on or prior to the Closing Date the conditions to Closing or
the Closing obligations, as the case may be, set forth in Sections 9.2(a),
9.2(b), 9.2(c), 9.2(e) or 10.2, Buyer, at its sole option, may (i) enforce
specific performance of this Agreement or (ii) terminate this Agreement and
recover from Seller the sum of $50,000,000.00, as liquidated damages.  Such remedies shall be Buyer’s sole and
exclusive remedies for such failure, all other remedies being expressly waived
by Buyer.  Seller and Buyer agree upon
such amount as liquidated damages due to the difficulty and inconvenience of
measuring actual damages and the uncertainty thereof, and Seller and Buyer
agree that such amount is a reasonable estimate of Buyer’s loss in the event of
any such failure by Seller.  Without
waiving or releasing Seller from any of its other representations, warranties,
covenants and agreements contained herein, specific performance with respect to
Section 10.2(b) shall not require Seller to make a false statement in the
officer’s certificate of Seller.

Section 15.9           Interpretation.  It is expressly agreed that this Agreement
shall not be construed against any party, and no consideration shall be given
or presumption made, on the basis of who drafted this Agreement or any
particular provision hereof or who supplied the form of Agreement.  Each party agrees that this Agreement has been

this Agreement, regardless of whether it appears before or after the place
where it is defined;

(d)           each Exhibit and Schedule to this
Agreement is a part of this Agreement, but if there is any conflict or

judicial means in any jurisdiction.  In

American Arbitration Association and the Arbitration Procedures, the Arbitration

contained herein, receive any rights hereunder or be a third party beneficiary
of this Agreement.  Any Indemnified

party Indemnified Person pursuant to Section 13.3; and no party shall have any
direct liability or obligation to any third party or be liable to any third
party for any election or non-election or any act or failure to act under or in

Agreement, or any application thereof, is held invalid, illegal or
unenforceable in any respect under any Law, this Agreement shall be reformed to
the extent necessary to conform, in each case consistent with the intention of
the parties, to such Law, and to the extent such term, provision or condition
cannot be so reformed, then such term, provision or condition (or such invalid,
illegal or unenforceable application thereof) shall be deemed deleted from (or
prohibited under) this Agreement, as the case may be, and the validity,
legality and enforceability of the remaining terms, provisions and conditions
contained herein (and any other application such term, provision or condition)
shall not in any way be affected or impaired thereby.  Upon such determination that any term or
other provision is invalid, illegal or incapable of being enforced, the parties
hereto shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the parties as closely as possible in an acceptable
manner to the end that the transactions contemplated hereby are fulfilled to
the extent possible.

Section 15.14         No

party’s right to file suit to compel arbitration to enforce its rights under
this Agreement, Buyer and Seller expressly covenant and agree not to record or
place of record this Agreement or any copy or memorandum hereof.
