to cause such entity to take or refrain from taking any actions.

 

ARTICLE II

CONSIDERATION;
CLOSING

 

Section 2.1                                      Contribution.

 

(a)                                  Agreement
of Contribution; Consideration. Subject to and in accordance with the terms
and conditions of this Agreement, Quicksilver hereby agrees to contribute to
BreitBurn, and BreitBurn hereby agrees to acquire from Quicksilver, (i) the
QRI Assets in exchange for Seven Hundred Fifty Million Dollars ($750,000,000)
(provided, BreitBurn may increase such cash consideration by notice to
Quicksilver no later than the third (3rd) Business Day preceding the
scheduled Closing Date), plus 10,216,529 Common Units (the “QRI Assets
Equity Consideration”), and (ii) the Equity Interests in exchange for
11,131,443 Common Units (the “Equity Interests Equity Consideration”)
(collectively, the “Initial Consideration”), as adjusted in accordance
with the other terms of this Agreement. The number of Common Units comprising
the Equity Consideration was established by Quicksilver and BreitBurn based on
the closing price of the Common Units as of August 24, 2007. The number of
Common Units included in the Equity Consideration multiplied by the closing
price of the Common Units on August 24, 2007, when added to $750,000,000
in cash consideration, equals $1,450,000,000.

 

(b)                                 Closing
Date Consideration; Final Consideration.

 

(i)                                     At
Closing, BreitBurn shall pay to Quicksilver, in accordance with Section 2.1(b)(ii) below,
the Initial Consideration, adjusted as follows: (i) plus or minus the
adjustments set forth in Sections 2.3-2.6 below, (ii) plus or minus
the adjustments, if any, set forth in Section 6.12, (iii) minus
the adjustments, if any, set forth in Section 6.13, and (iv) minus
the adjustments, if any, set forth in Section 6.14 (the Initial
Consideration, as so adjusted at Closing, is herein referred to as the “Closing
Date Consideration”). The Closing Date Consideration shall be further
adjusted post-Closing in accordance with the terms of Sections 2.5-2.6
(the Closing Date Consideration, as so adjusted, the “Final Consideration”).
Any upward or downward adjustment to be made pursuant to clauses (i) through
(iv) above shall be made by increasing or reducing (as applicable) the
Equity Interests Equity Consideration by a number of Common Units determined by
dividing (A) the difference between the Initial Consideration and the
Closing Date Consideration, by (B) $32.79; provided, if either such
adjustment involves an increase in the Initial Consideration or Closing Date
Consideration, BreitBurn may elect to pay such increase in cash.

 

23

 

(ii)                                  The
Closing Date Consideration shall be paid as follows: (A) Seven Hundred
Fifty Million Dollars ($750,000,000) (or such greater amount as may be
designated by BreitBurn pursuant to a notice given to Quicksilver pursuant to Section 2.1(a)(i))
of the Closing Date Consideration shall be paid via wire transfer of
immediately available funds to the account(s) designated by Quicksilver (the “Cash
Consideration”); and (B) the remainder of the Closing Date
Consideration shall be paid through the issuance of the QRI Assets Equity
Consideration and the Equity Interests Equity Consideration; provided, if the
Cash Consideration exceeds $750,000,000 (such excess being herein referred to
as “Additional Cash Consideration”), the QRI Assets Equity Consideration
shall be reduced by a number of Common Units determined by dividing the
Additional Cash Consideration by $32.79.

 

(iii)                               If
the number of Common Units comprising the Equity Consideration does not result
in a whole number then it shall be rounded up to the nearest whole number of
Common Units. If BreitBurn Parent shall at any time prior to the Closing
subdivide its Common Units, by split-up or otherwise, or combine its Common
Units, or issue additional Common Units as a dividend or distribution with
respect to any Common Units, appropriate adjustments shall be made to the
number of Common Units issuable to Quicksilver hereunder. Quicksilver shall
designate in writing the account(s) for payment of the Cash Consideration at
least three (3) days prior to Closing.

 

Section 2.2                                      Deposit.

 

(a)                                  Concurrently
with the execution of this Agreement, BreitBurn has deposited by wire transfer
in same day funds into escrow with Quicksilver the sum of Thirty-Five Million
Dollars ($35,000,000) (the “Deposit”). If Closing occurs, the Deposit
shall be applied toward (and thus shall be deemed the payment by BreitBurn of
an equivalent amount of) the Cash Consideration at Closing, without any
interest earned thereon.

 

(b)                                 If
(i) all conditions precedent to the obligations of BreitBurn to consummate
the transactions contemplated by this Agreement set forth in Article VII
have been met, and (ii) this Agreement is terminated prior to Closing for
reasons described in Section 8.1(e), then, in such event,
Quicksilver shall be entitled to recover from BreitBurn an amount equal to the
Damages Quicksilver suffers as a result of such termination and shall have the
right, upon such termination, to retain the Deposit, and if the amount of such
Damages determined by a court of competent jurisdiction or by the mutual
agreement of the Parties (x) is equal to or in excess of the Deposit, apply the
Deposit toward the amount of such Damages so determined or (y) is less than the
Deposit, promptly return to BreitBurn an amount equal to the amount by which
the Deposit exceeds such Damages.

 

(c)                                  If
this Agreement is terminated prior to Closing, for any reason described in Section 8.1
(other than Section 8.1(e)), then within five (5) Business
Days following such termination, BreitBurn shall be entitled to the return and
delivery of the Deposit, without any interest or earnings thereon; and except
as expressly set forth in Article VIII, BreitBurn and

 

24

 

Quicksilver shall
thereafter have no further liability or obligation to each other with regard to
this Agreement or the transactions covered hereby.

(the “Preliminary Settlement Statement”). Within two (2) Business
Days of receipt of the Preliminary Settlement Statement, BreitBurn will deliver
to Quicksilver a written report containing all changes with the explanation
therefor that BreitBurn proposes to be made to the Preliminary Settlement
Statement. The Preliminary Settlement Statement, as agreed upon by the Parties,
will be used to adjust the Initial Consideration at Closing; provided, however, that to the extent the Parties do not
mutually agree, then the Parties shall utilize the Preliminary Settlement
Statement submitted by Quicksilver, solely for purposes of calculating the
Closing Date Consideration.

 

(c)                                  Final Settlement Statement. On or before one hundred twenty
(120) days after Closing, BreitBurn shall prepare and deliver to Quicksilver a
proposed final settlement statement (the “Final Settlement Statement”),
setting forth (i) all adjustments contemplated under Sections 2.3
and 2.4, based on actual income, expenses and other amounts contemplated
in Sections 2.3 and 2.4; and (ii) BreitBurn’s calculation,
as of the Closing Date, of: (A) Net Working Capital of the Transferred
Companies (the “Closing Net Working Capital”) and (B) all of the
cash and cash equivalents of the Transferred Companies (excluding cash proceeds
received with respect to any casualty event or loss incurred on or after the
date hereof and any cash to be eliminated at Closing pursuant to Section 6.7)
(collectively, the “Closing Cash”); and (iii) any further payments
required under Sections 6.12, 6.13 or 6.14, if any. BreitBurn
shall at Quicksilver’s request promptly deliver to Quicksilver reasonable
documentation available to support any credit, charge, receipt or other item
included in the Final Settlement Statement. As soon as practicable, and in any
event within thirty (30) days, after receipt of the Final Settlement
Statement, Quicksilver shall return a written report containing any proposed
changes to the Final Settlement Statement and an explanation of any such
changes and the reasons therefor (the “Dispute Notice”). Within twenty
(20) days following the date of delivery of the Dispute Notice (the “Resolution
Period”), the Parties shall attempt to agree on all items in the Final
Settlement Statement and any proposed changes to the Final Settlement Statement
set forth in the Dispute Notice. If the Final Settlement Statement (including
proposed changes thereto) is mutually agreed upon by Quicksilver and BreitBurn
in writing, the Final Settlement Statement (including any changes mutually
agreed upon by Quicksilver and BreitBurn in writing), shall be final and binding
on the Parties. Any disputes with respect to the items in the Final Settlement
Statement and the Dispute Notice raised in writing prior to the end of the
Resolution Period shall be resolved in accordance with Section 2.6
below. Any disputes with respect to the items in the Final Settlement Statement
and the Dispute Notice that are not raised in writing by BreitBurn or
Quicksilver prior to the end of the Resolution Period shall be waived, except
disputes with respect to Title Defects, Environmental Defects, Taxes and other
matters that are expressly provided to be determined pursuant to other
provisions of this Agreement. Any difference in the Closing Date Consideration
as paid at Closing pursuant to the Preliminary Settlement Statement and the
amounts set forth in the Final Adjustment Statement (as defined in Section 2.6)
shall be paid by the owing Party to the owed Party within ten (10) days
following the date on which (x) the Final Adjustment Statement is mutually
agreed upon by Quicksilver and BreitBurn or (y) the final determination is made
by the Neutral Auditor in accordance with Section 2.6, as
applicable.

 

27

 

All amounts
paid pursuant to this Section 2.5(c) shall be delivered in
United States currency by wire transfer of immediately available funds to the
account specified in writing by the relevant Party. Payments due under this Section 2.5(c) shall
be paid to the applicable Party together with interest at the Interest Rate
from, and including, the Closing Date to, but excluding, the date of payment.

 

Section 2.6                                      Disputes. If after Closing, either Quicksilver or BreitBurn, as the case may be,
timely notifies the other of any disputed items with regard to the post-Closing
adjustments contemplated in Section 2.5(c) in accordance with
the terms thereof, and if at the conclusion of the Resolution Period under Section 2.5(c) Quicksilver
and BreitBurn have not reached an agreement on such disputed items, then all
items remaining in dispute, and not waived pursuant to Section 2.5(c),
shall be submitted by Quicksilver and BreitBurn to a nationally recognized
independent auditor as to which the Parties shall reasonably agree within ten (10) days
following the expiration of the Resolution Period (the “Neutral Auditor”).
All fees and expenses relating to the work, if any, to be performed by the
Neutral Auditor pursuant to this Section 2.6 shall be borne fifty
percent (50%) by Quicksilver and fifty percent (50%) by BreitBurn. Except as
provided in the preceding sentence, all other costs and expenses incurred by
the Parties in connection with resolving any dispute hereunder before the
Neutral Auditor shall be borne by the Party incurring such cost and expense.
The Neutral Auditor shall act as an arbitrator to determine only those items
still in dispute at the end of the Resolution Period, and may not award
damages or penalties to either Party with respect to any matter. The Neutral
Auditor shall not determine any matter required to be determined by the Title
Arbitrator or the Independent Expert pursuant to Section 6.12 or Section 6.14.
The Neutral Auditor shall conduct the arbitration proceedings in Dallas, Texas
in accordance with the Commercial Arbitration Rules of the American
Arbitration Association, to the extent such rules do not conflict with the
terms of this Section. In no event shall the Neutral Auditor’s determination be

the foregoing, to the extent an amount in the Final Settlement Statement is

Subsidiaries are owned, directly or indirectly, by BreitBurn Parent free and
clear of any Liens (except for such restrictions as may exist under
applicable Law and except for such Liens as may be set forth in Schedule 5.10(d))
and all such ownership interests have been duly authorized, validly issued and
are fully paid (to the extent required by applicable Law or in the
organizational documents of BreitBurn Parent’s Subsidiaries, as applicable) and
nonassessable (except as nonassessability may be affected by matters
described in Section 17-303, 17-607 and 17-804 of the Delaware LP Act and

BreitBurn Parent SEC Documents, neither BreitBurn Parent nor any of its
Subsidiaries owns any shares of capital stock or other securities of, or

(e)                                  The
issuance of the Common Units comprising the Equity Consideration and the
limited partner interests represented thereby has been duly authorized by
BreitBurn Parent pursuant to the Partnership Agreement and, when issued and
delivered to Quicksilver in accordance with the terms of this Agreement, will
be validly issued, fully paid (to the extent required by applicable Law and the
Partnership Agreement) and nonassessable (except as such nonassessability may be
affected by Sections 17-303, 17-607 and 17-804 of the Delaware LP Act) and will
be free of any and all Liens and restrictions on transfer, other than
restrictions on transfer under the Partnership Agreement, this Agreement and
under applicable state and federal securities Laws and other than such Liens as
are created by Quicksilver.

 

(f)                                    The
Common Units comprising the Equity Consideration will be issued in compliance
with all applicable rules of The Nasdaq Global Market. Prior to the
Closing Date, BreitBurn Parent will submit to The Nasdaq Global Market a
Notification Form:  Listing of Additional
Common Units with respect to the Common Units comprising the Equity
Consideration. BreitBurn Parent’s currently outstanding Common Units are quoted
on The Nasdaq Global Market and BreitBurn Parent has not received any notice of
delisting.

 

Section 5.11                                SEC Documents. BreitBurn Parent has filed timely with the
SEC all forms, registration statements, reports, schedules and statements
required to be filed by it under the Exchange Act or the Securities Act (all
such documents filed on or prior to the date of this Agreement, collectively,
the “BreitBurn Parent SEC Documents”). The BreitBurn Parent SEC
Documents, including, without limitation, any audited or unaudited financial
statements and any notes thereto or schedules included therein (the “BreitBurn
Parent Financial Statements”), at the time filed (in the case of
registration statements, solely on the dates of effectiveness) (except to the
extent corrected by a subsequently filed BreitBurn Parent SEC Document filed
prior to the date hereof) (i) did not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein (in the case of any
prospectus, in light of the circumstances under which they were made) not
misleading, (ii) complied as to form in all material respects with
the applicable requirements of the Exchange Act and the Securities Act, as
applicable, (iii) in the case of the BreitBurn Parent Financial
Statements, complied as to form in all material respects with applicable
accounting requirements and with the published rules and regulations of
the SEC with respect thereto, (iv) in the case of the BreitBurn Parent
Financial Statements, were prepared in accordance with GAAP applied on a

 

45

 

consistent
basis during the periods involved (except as may be indicated in the notes
thereto or, in the case of unaudited statements, as permitted by Form 10-Q
of the SEC) and (v) in the case of the BreitBurn Parent Financial
Statements, fairly present (subject in the case of unaudited statements to
normal, recurring and year-end audit adjustments) in all material respects the
consolidated financial position of BreitBurn Parent and its Subsidiaries as of
the dates thereof and the consolidated results of its operations and cash flows
for the periods then ended. PricewaterhouseCoopers LLP is an independent
registered public accounting firm with respect to BreitBurn Parent and the
General Partner and has not resigned or been dismissed as independent
registered public accountants of BreitBurn Parent and the General Partner as a
result of or in connection with any disagreement with BreitBurn Parent or the
General Partner on a matter of accounting principles or practices, financial
statement disclosure or auditing scope or procedure.

 

Section 5.12                                Tax.
For United States federal Tax purposes (and state, local, and foreign Tax
purposes where applicable), BreitBurn is disregarded as an entity separate from
BreitBurn Parent. BreitBurn Parent is, and has only been, classified as either
a disregarded entity or a partnership for United States federal Tax purposes (and
state, local, and foreign Tax purposes where applicable). BreitBurn Parent
does, and reasonably expects to continue to, meet the gross income requirements
of Section 7704(c)(2) of the Code, and BreitBurn Parent is not, and
does not reasonably expect to be, treated as a corporation under Section 7704(a) of
the Code or Treasury Regulations section 301.7701-2.

 

Section 5.13                                Investment Company Status. BreitBurn Parent is not now, and after the
issuance of the Common Units comprising the Equity Consideration will not be,
and is not controlled by or under common control with, an “investment company”
within the meaning of the Investment Company Act of 1940, as amended.

 

Section 5.14                                Offering. Assuming the accuracy of the representations and warranties of
Quicksilver contained in Section 3.5 of this Agreement, the
issuance of the Common Units comprising the Equity Consideration pursuant to
this Agreement is exempt from the registration requirements of the Securities
Act, and neither BreitBurn Parent nor any authorized representative acting on
its behalf has taken or will take any action hereafter that would cause the
loss of such exemption.

 

Section 5.15                                Internal Accounting Controls. BreitBurn Parent and its Subsidiaries
maintain a system of internal accounting controls sufficient to provide
reasonable assurance that (i) 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 and (iii) access
to assets is permitted only in accordance with management’s general or specific
authorization.

 

Section 5.16                                Material Agreements. BreitBurn has provided Quicksilver with, or
made available to Quicksilver through the BreitBurn Parent SEC Documents,
correct and complete copies of all material agreements (as defined in Section 601(b)(10) of
Regulation S-K promulgated by the SEC) and of all exhibits to the BreitBurn
Parent SEC Documents, including amendments to or other modifications of
pre-existing material agreements, entered into by BreitBurn Parent.

BreitBurn’s approval of any action restricted by clause (B), (G), (M)
or (P) of this Section 6.1(b)(ii) shall not be unreasonably
withheld or delayed and shall be considered granted within ten (10) days
(unless a shorter time is reasonably required by the circumstances and such
shorter time is specified in Quicksilver’s notice) of Quicksilver’s notice to
BreitBurn requesting such consent unless BreitBurn notifies Quicksilver to the
contrary during that period. Notwithstanding the foregoing provisions of this Section 6.1,
in the event of an emergency, Quicksilver may take such action as reasonably
necessary and shall notify BreitBurn of such action promptly thereafter.

 

48

 

Section 6.2                                      Efforts;
Cooperation; HSR and Other Filings.

 

(a)                                  Subject
to the terms and conditions of this Agreement, each of the Parties will 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 this Agreement or which would prevent it from delivering to the other
Party the certificates which it is required to deliver pursuant to Section 2.11(c) or
2.12(c), as the case may be.

 

(b)                                 BreitBurn
and Quicksilver shall timely and promptly make all filings which may be
required by any of them by Law in connection with the consummation of the
transactions contemplated hereby, including, without limitation, those filings
required under the Hart-Scott Act; provided, however,
that the Parties shall make all filings required by either of them under the
Hart-Scott Act within ten (10) Business Days after the date hereof. Each
Party shall furnish to the other Party such necessary information and
assistance as such other Party may reasonably request in connection with
the preparation of any necessary filings or submissions by it to any
Governmental Entity and correspondence, filings or communications (or memoranda
setting forth the substance thereof) between such Party and its representatives
and the Federal Trade Commission, the Antitrust Division of the United States
Department of Justice or any other Governmental Entity and members of their
respective staffs with respect to this Agreement and the transactions
contemplated hereby. With the exception of payment of the required filing fees
and the Parties’ costs and expenses necessary to prosecute such filings,
neither Quicksilver nor BreitBurn shall be required to make any material
monetary expenditures, commence or participate in any material litigation, or
offer or grant any material accommodation (financial or otherwise) to any third
Person in connection therewith; provided, however,
that any filing fees incurred in connection with filings made in accordance
with the Hart-Scott Act in connection with the consummation of the transactions
contemplated in this Agreement, shall be paid and borne solely by BreitBurn.

 

Section 6.3                                      Public
Disclosures. Prior to the Closing Date and for a period of thirty (30) days
following the Closing Date, no Party will (and each Party will ensure that its
Affiliates and their respective representatives will not) issue any press
release or make any public disclosure concerning the transactions contemplated
by this Agreement without the prior written consent of the other Party, which
shall not be unreasonably withheld, delayed or conditioned. Notwithstanding the
above, nothing in this Section 6.3 will preclude any Person from
making any disclosures it reasonably believes are required by Law or stock
exchange rules or necessary and proper in conjunction with the filing of
any Tax Return or other document required to be filed with any Governmental
Entity; provided that the respective Party shall endeavor to allow the other
Party reasonable time to review and comment thereon in advance of such
disclosure.

 

Section 6.4                                      Pre-Closing
Access; Post-Closing Delivery and Access to Records and Personnel.

 

(a)                                  Pre-Closing Access. From and after the date of this
Agreement, but subject to the other provisions of this Section 6.4,
Section 6.14(a) and subject to obtaining any required consents
of third-party operators, Quicksilver will, and will cause the Acquired
Companies to, afford BreitBurn and its representatives access, during normal
business hours, to the Acquired Assets and offices, personnel and all books and
records of Quicksilver and the

 

49

 

Acquired
Companies regarding the Acquired Assets in order for BreitBurn to conduct an
Environmental Assessment in accordance with Section 6.14(a) and
a title examination with respect to the Oil and Gas Properties in order to determine
whether Title Defects or Environmental Defects exist, insofar as such books and
records are in possession of Quicksilver or the Acquired Companies and can be
disclosed without consent or approval of any third party or would not result in
the loss or waiver of any legal right or privilege; provided further
Quicksilver and the Acquired Companies will use their reasonable efforts to
obtain a waiver of any such third party restrictions in favor of BreitBurn, but
without being obligated to pay any consideration or waive or release any right
or privilege to obtain such waiver. Subject to the foregoing, BreitBurn and its
representatives may examine all abstracts of title, title opinions, title
files, ownership maps, lease files, assignments, division orders, operating
records and agreements, well files, financial and accounting records,
geological, geophysical, engineering and environmental records, in each case
insofar as the same relate to the Interests and may now be in existence
and in the possession of Quicksilver and the Acquired Companies. BreitBurn will
not contact any of the customers or suppliers of Quicksilver or the Acquired
Companies or their Working Interest co-owners, operators, lessors or surface
interest owners, in connection with the transactions contemplated hereby
without the specific prior authorization of Quicksilver, which consent will not
be unreasonably withheld and may be made subject to reasonable
restrictions. BreitBurn shall coordinate its physical inspections of the
Acquired Assets with Quicksilver to minimize any inconvenience to or
interruption of the conduct of Business. BreitBurn shall abide by all of
Quicksilver’s safety rules, regulations, and operating policies while
conducting its due diligence evaluation of the Acquired Assets. Any
Environmental Assessment shall also be subject to the further provisions of Section 6.14(a).
In addition, BreitBurn agrees to the following with regard to such pre-Closing
diligence activities, including any Environmental Assessment:

 

(i) 
BreitBurn agrees to promptly provide Quicksilver, but in no less than five (5) Business
Days after receipt or creation, copies of all reports and test results,
prepared by BreitBurn and/or any of BreitBurn’s representatives and which
contain data collected or generated from BreitBurn’s due diligence with respect
to the Acquired Assets. Quicksilver shall not be deemed by its receipt of said
documents or otherwise to have made any representation or warranty, expressed,
implied or statutory, as to the condition to the Acquired Assets or to the
accuracy of said documents or the information contained therein.

 

(ii) Upon
completion of BreitBurn’s due diligence, BreitBurn shall, at its sole cost and
expense and without any cost or expense to Quicksilver or the Transferred Companies:
(1) repair all damage done to the Acquired Assets in connection with
BreitBurn’s due diligence, (2) restore the Acquired Assets to the
approximate same or better condition than it was prior to commencement of
BreitBurn’s due diligence and (3) remove all equipment, tools or other
property brought onto the Acquired Assets in connection with BreitBurn’s due
diligence. Any disturbance to the Acquired Assets (including, without
limitation, the real property associated with such Acquired Assets) resulting
from BreitBurn’s due diligence will be promptly corrected by BreitBurn.

 

50

 

(iii) 
BreitBurn hereby agrees to DEFEND, RELEASE, INDEMNIFY and HOLD HARMLESS each of
Quicksilver, the Transferred Companies, any third-party operators of any of the
Acquired Assets, and each of the other Quicksilver Indemnified Parties, from
and against any and all Damages arising out of, resulting from or relating to
any field visit, Environmental Assessment, or other due diligence activity
conducted by BreitBurn or any of BreitBurn’s employees, agents, consultants, or
representatives, EVEN
IF SUCH DAMAGES ARISE OUT OF OR RESULT FROM, SOLELY OR IN PART, THE SOLE,
ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR
OTHER FAULT OR VIOLATION OF LAW OF OR BY QUICKSILVER, ANY OF THE TRANSFERRED
COMPANIES, ANY OTHER MEMBER OF THE QUICKSILVER INDEMNIFIED PARTIES OR ANY OTHER
PERSON, EXCLUDING QUICKSILVER’S OR ANY TRANSFERRED COMPANY’S GROSS NEGLIGENCE
OR WILLFUL MISCONDUCT; PROVIDED,  HOWEVER, THAT, FOR THE PURPOSES
OF THIS SECTION 6.4(a)(iii), DAMAGES SHALL NOT INCLUDE DAMAGES TO
THE EXTENT RESULTING SOLELY FROM THE DISCOVERY BY BREITBURN, ITS OFFICERS,
DIRECTORS, AGENTS, REPRESENTATIVES, EMPLOYEES, SUCCESSORS OR ASSIGNS OF ANY
PRE-EXISTING CONDITION.

 

(b)                                 Post-Closing Delivery of Books and Records. Quicksilver
shall deliver to BreitBurn, within fifteen (15) Business Days following the
Closing Date, all books, records, documents, instruments, accounts,
correspondence, writings, Contracts, evidences of title and other papers (in
each case, including electronic versions thereof) relating to the Acquired
Assets or the Transferred Companies, to the extent in the possession of
Quicksilver or any Affiliate of Quicksilver (including the Acquired Companies)
and to the extent not constituting the Excluded Assets (collectively, the “Books
and Records”). Quicksilver may retain copies of any or all of the
Books and Records for its files.

 

(c)                                  Post-Closing Retention of Books and Records. BreitBurn shall
retain the Books and Records for the period of time set forth in its records
retention policies on the Closing Date which shall not be less than  six (6) years (or for tax
records, seven years), or for such longer period as may be required by Law
or any applicable court Order, or for the term required by BreitBurn’s records
retention policy. At any time during such period, Quicksilver may, upon its
request and at its expense, copy all or any part of such Books and Records
as Quicksilver may reasonably require. Notwithstanding the foregoing,
BreitBurn shall retain (or cause the Acquired Companies to retain) for such
longer periods any and all Books and Records that relate to any ongoing Action
until such time as BreitBurn is notified of the final conclusion of such
matter.

 

(d)                                 Reasonable Post-Closing Access. After Closing, the Parties
will allow each other reasonable access to the Books and Records, and to
personnel having knowledge of the whereabouts or contents of such Books and
Records, for legitimate legal, tax or accounting reasons, such as the
preparation of Tax Returns, the defense of Actions and responding to data
requests from Governmental Entities. Subject to Article IX, each
Party shall be entitled to

 

51

 

recover its
out-of-pocket costs (including copying costs) incurred in providing such
records or personnel to the other Party.

 

Section 6.5                                      Employee
Matters.

 

(a)                                  Quicksilver
shall use its good faith efforts to make available to BreitBurn all of the
Business Employees listed on Schedule 4.12, to discuss potential
employment with BreitBurn or an Affiliate of BreitBurn on and after Closing
(such entity that makes any employment offers is herein referred to as the “BreitBurn
Employer”). BreitBurn shall provide Quicksilver, in writing, not later than
fourteen (14) calendar days prior to the Closing Date, a list of those Business
Employees to whom BreitBurn intends to make offers of employment effective as
of the Closing Date, together with the proposed terms of such employment
(collectively, the “Designated Employees”); and BreitBurn shall cause
the BreitBurn Employer to make offers of employment to the Designated Employees
on the terms provided to Quicksilver, effective as of the Closing Date. BreitBurn’s
determination as to which Business Employees shall be Designated Employees and
the proposed terms of employment offered by the BreitBurn Employer, shall be
within the sole discretion of BreitBurn; provided, however,
that its election and determination shall be made in accordance with all
applicable Law (and upon delivery of the written notification of the Designated
Employees to Quicksilver, as described above, BreitBurn shall be deemed to have
represented, warranted and certified to Quicksilver that its determination has
been made in accordance with all applicable Law).

 

(b)                                 For
a period of two (2) years following the Closing Date, Quicksilver shall
not, directly or indirectly solicit for employment, by Quicksilver or any
Affiliate of Quicksilver, any Designated Employee who accepts a job with
BreitBurn or an Affiliate of BreitBurn pursuant to the offers of employment
made pursuant to Section 6.5(a), unless (in each case prior to any
such solicitation) such Designated Employee is no longer employed by BreitBurn
or BreitBurn’s Affiliates; provided, however,
that Quicksilver shall not be precluded from hiring any employee who has been
terminated by BreitBurn or BreitBurn’s Affiliate prior to commencement of
employment discussions between Quicksilver and such employee. Quicksilver
acknowledges that the purpose of this covenant is to enable BreitBurn to
maintain a stable workforce in order to remain in Business, and that it would
disrupt, damage, impair and interfere with the Business if Quicksilver were to
engage in the solicitation prohibited hereby.

 

Section 6.6                                      Workforce
Reduction Notices. Quicksilver shall be responsible for any workforce
reductions carried out on or before the Closing Date and such reductions, if
any, shall be done in accordance with all applicable Laws and regulations
governing the employment relationship and termination thereof, including, if
applicable, the Worker Adjustment and Retraining Notification Act (“WARN”)
and regulations promulgated thereunder, and any comparable state or local Law. BreitBurn
shall not be responsible for any obligations under WARN or its equivalent state
statutes and any applicable regulations thereunder with respect to any
employment terminations on or prior to the Closing Date.

 

Section 6.7                                      Inter-Company
Transactions; Insurance.

 

(a)                                  Except
as set forth in Schedule 6.7(a), effective as of Closing, all
inter-company receivables or payables then existing between Quicksilver and any
Affiliates of

 

52

 

Quicksilver
(other than the Acquired Companies), on the one hand, and any of the Acquired
Companies on the other, shall be cancelled or settled by making inter-company
cash transfers so that there are no outstanding payables. If the Acquired
Companies fail to have sufficient cash on hand to pay such payables or
receivables or other liabilities in full, then Quicksilver shall nonetheless
cause all such remaining payables or receivables to be canceled as of Closing
without further liability relating to such inter-company transactions.

 

(b)                                 Notwithstanding
their exclusion from Current Assets, any insurance proceeds receivable of the
Acquired Companies for casualty losses suffered by the Acquired Companies
before, on or after the date of this Agreement shall remain with the Acquired
Companies, as applicable, after Closing. If any casualty losses are incurred by
the Acquired Companies after the date of this Agreement and prior to Closing,
and such losses are insured by Quicksilver’s insurance policies, then Quicksilver
shall use commercially reasonable efforts to make claims relating to those
losses and Quicksilver shall pay to the Acquired Companies any amounts received
by Quicksilver pursuant to such claims, less any collection costs. The Acquired
Companies may use any proceeds of such insurance receivables to repair
property damage or replace the property on account of which such casualty
insurance proceeds have been paid to a Acquired Company.

 

Section 6.8                                      Release
of Guarantees and Bonds. BreitBurn acknowledges that none of the bonds,
letters of credit and guarantees, if any, posted by Quicksilver or its
Affiliates with Governmental Entities and relating to the Acquired Assets or
the other Interests and set forth on Schedule 6.8 (collectively,
the “Bonds”) are transferable to BreitBurn. On or before the Closing
Date, BreitBurn shall obtain, or cause to be obtained in the name of BreitBurn
or its designee, replacements for such Bonds to the extent such replacements
are necessary to permit the cancellation and complete release of the Bonds
posted by Quicksilver and/or such Affiliates. In addition, at or prior to
Closing, BreitBurn shall deliver to Quicksilver evidence of the posting of
bonds or other security with all applicable Governmental Entities meeting the requirements
of such authorities to own and, where appropriate, operate, the Acquired
Assets, the Acquired Companies, or the other Interests.

 

Section 6.9                                      Amendments
of Disclosure Schedules.

 

(a)                                  Prior
to Closing, Quicksilver may, from time to time, by delivering a written copy
thereof to BreitBurn, supplement or amend its disclosure schedules attached to
this Agreement relating to any representations or warranties of Quicksilver
(collectively, the “Disclosure Schedules”), to include reference to any
matter relating to Quicksilver, the Acquired Assets, the Interests or the
Transferred Companies which first arises or occurs after the date of execution
of this Agreement and does not result from a breach by Quicksilver of any
covenant set forth in Article VI.

 

(b)                                 Any
such supplement or amendment of any such Disclosure Schedule by
Quicksilver under Section 6.9(a) above will be effective to
cure and correct any breach of any representation or warranty that would have
existed absent such amendment or supplement, and BreitBurn shall have no right,
and hereby waives any and all rights, to bring any claim in respect of or
relating to such breach of representation or warranty.

Section 6.10                                Removal
of Quicksilver Identification. BreitBurn shall, and shall cause its
Affiliates and Subsidiaries to, not use the name “Quicksilver” (or any
variations or derivatives thereof); and, within ninety (90) days after the
Closing Date, BreitBurn shall, and shall cause the Acquired Companies, to
remove, destroy or completely obscure (e.g., paint
over) all visible names, symbols, tradenames, trademarks and logos of “Quicksilver”
with regard to any assets of the Acquired Companies or with regard to the
Acquired Assets.

 

Section 6.11                                Assigned
QRI Assets. Quicksilver shall use commercially reasonable efforts to
procure any required third-party consents necessary to transfer the QRI Assets
to BreitBurn, but without being obligated to pay any consideration or waive or
release any right or privilege to obtain such consent. If the Parties are not
able to effect the assignment of any of the QRI Assets at Closing due to the
lack of a required third-party consent to transfer the same, such QRI Assts
shall not be deemed assigned at Closing via the Asset Assignments. Until any
such consents are obtained and the non-assigned QRI Assets are assigned, to the
extent permissible under Law and under the terms of any Contracts applicable
thereto, Quicksilver shall use commercially reasonable efforts post-Closing to (i) continue
to perform the liabilities and obligations under or with regard to any
non-assigned QRI Assets, (ii) hold such non-assigned QRI Assets in trust
for the benefit of BreitBurn and shall promptly forward to BreitBurn, any
monies or other benefits received that are attributable to such non-assigned
QRI Assets, and (iii) endeavor to mutually agree with BreitBurn to
institute alternative arrangements intended to put the Parties in substantially
the same economic position as if such non-assigned QRI Assets had been assigned.
BreitBurn shall promptly reimburse Quicksilver for, and shall DEFEND, INDEMNIFY  AND HOLD HARMLESS
all Quicksilver Indemnified Parties from and against, any and all fees, costs,
expenses and Damages incurred by Quicksilver or any Quicksilver Indemnified
Party in connection with any action taken by Quicksilver pursuant to the
preceding sentence, IN EACH CASE, REGARDLESS
OF THE SOLE, JOINT, CONCURRENT, COMPARATIVE, CONTRIBUTORY, ACTIVE, PASSIVE OR
GROSS NEGLIGENCE, WILLFUL MISCONDUCT, STRICT LIABILITY OR OTHER FAULT OR
RESPONSIBILITY OF ANY KIND OF QUICKSILVER, BREITBURN, THE TRANSFERRED
COMPANIES, OR ANY OTHER PARTY OR PERSON. If the foregoing
arrangements are not permissible under Law or under the terms of any Contracts
applicable thereto, then the Parties shall use commercially reasonable efforts
to take such other actions or put into place such other arrangements as are
permissible with regard to the non-assigned QRI Assets so as to provide the
Parties with the same economic results as would otherwise have resulted.

 

Section 6.12                                Title
Defects; Title Defect Procedure and Adjustments.

 

(a)                                  Title Defect Notices. On or before 5:00 p.m. (Eastern
Time) of the fifth (5th) day before Closing (the “Title Claim Date”),
BreitBurn may deliver claim notices to Quicksilver meeting the
requirements of this Section 6.12(a) (collectively the “Title Defect Notices”
and individually a “Title
Defect Notice”) setting forth any matters which, in
BreitBurn’s good faith opinion, constitute Title Defects and which BreitBurn
intends to assert as a Title Defect pursuant to this Section 6.12.
For all purposes of this Agreement and notwithstanding anything herein to the
contrary, BreitBurn shall be deemed to have waived, and Quicksilver shall have
no liability for, any Title Defect which BreitBurn fails to assert as a Title
Defect by a Title Defect Notice received by Quicksilver on or before the Title
Claim Date. To

 

54

 

be effective,
each Title Defect Notice shall be in writing, and shall include (i) a
description of the alleged Title Defect(s), (ii) the Well(s) or well
location(s) (and the applicable zone(s) therein) and/or other Acquired Assets
affected by the Title Defect (each a “Title
Defect Property”), (iii) the allocated value of
each Title Defect Property as set forth on Schedule 6.12(a) (the “Preliminary
Allocated Value”), (iv) supporting documents reasonably necessary for
Quicksilver to verify the existence of the alleged Title Defect(s), and (v) the
amount by which BreitBurn reasonably believes the Preliminary Allocated Value
of each Title Defect Property is reduced by the alleged Title Defect(s) and the
computations upon which BreitBurn’s belief is based. To give Quicksilver an
opportunity to commence reviewing and curing Title Defects, BreitBurn agrees to
use reasonable efforts to give Quicksilver, on or before the end of each
calendar week prior to the Title Claim Date, written notice of all Title
Defects discovered by BreitBurn during the preceding calendar week, which
notice may be preliminary in nature and supplemented prior to the Title
Claim Date. BreitBurn shall also promptly furnish Quicksilver with written
notice of any Title Benefit which is discovered by any of BreitBurn’s or any of
its Affiliate’s employees, title attorneys, landmen or other title examiners
while conducting BreitBurn’s due diligence with respect to the Wells or Oil and
Gas Properties or other Acquired Assets prior to the Title Claim Date.

 

(b)                                 Title Benefit Notices. Quicksilver shall have the right, but
not the obligation, to deliver to BreitBurn on or before the Title Claim Date
with respect to each Title Benefit a notice (a “Title Benefit Notice”)
including (i) a description of the Title Benefit, (ii) the Wells or
well location(s) (and the applicable zone(s) therein) and/or other Acquired
Assets affected by the Title Benefit, and (iii) the amount by which
Quicksilver reasonably believes the Preliminary Allocated Value of those
Well(s) or well location(s) (and the applicable zone(s) therein) and/or other
Acquired Assets have increased by the Title Benefit, and the computations upon
which Quicksilver’s belief is based.

 

(c)                                  Quicksilver’s Right to Cure Title Defects. Quicksilver shall
have the right, but not the obligation, to attempt, at its sole cost, to cure
any asserted Title Defects at any time prior to Closing (the “Cure Period”).
If a Title Defect is reasonably susceptible of being cured but is not cured on
or before the Closing Date, BreitBurn and Quicksilver agree that Quicksilver
will also have the right to elect to (i) exclude the affected Title Defect
Property (other than Fixed Facilities that constitute Title Defect Properties)
from the contribution at Closing (and to the extent that such excluded Title
Defect Property is currently held by a Acquired Company, then it will be
transferred to Quicksilver prior to Closing), (ii) attempt to cure such
defect (and attempt to cure any such defect with respect to Fixed Facilities
that constitute Title Defect Properties) for a period of up to ninety (90) days
after the Closing Date, and until cured, the Preliminary Allocated Value of
such excluded Title Defect Property (and, in the case of Fixed Facilities that
constitute Title Defect Properties, the Title Defect Amount determined under
this Section 6.12 with respect thereto) will be withheld from the
Closing Date Consideration at Closing. If cured within this 90-day period,
then, within five (5) Business Days after such Title Defect is cured, (x)
BreitBurn shall pay and deliver to Quicksilver the Preliminary Allocated Value
(or the Title Defect Amount) therefor, as applicable, which was deducted from
the Closing Date Consideration, together with interest at the Interest Rate
from, and including, the Closing Date to, but excluding, the date of payment,
and (y) Quicksilver will deliver to BreitBurn an assignment of such Title
Defect Property if withheld at Closing, upon the same terms and conditions set
forth in the Asset Assignments. BreitBurn shall provide Quicksilver and their

 

55

 

representatives
access to the other Acquired Assets, and all Books and Records after Closing in
connection with Quicksilver’s efforts to cure the alleged defect. If,
post-Closing, the Parties dispute whether such Title Defect has been cured,
then the matter shall be resolved in a manner described in Section 6.12(i) below,
and the post-Closing payment and delivery of the assignment, if any, provided
for in this Section 6.12(c) shall be made as provided in this Section 6.12(c) when
such dispute is resolved pursuant to Section 6.12(i).

 

(d)                                 Remedies for Title Defects. Subject to Quicksilver’s
continuing right to dispute the existence of a Title Defect and/or the Title
Defect Amount asserted with respect thereto, in the event that any Title Defect
timely asserted by BreitBurn in accordance with this Section 6.12
is not waived in writing by BreitBurn or cured on or before Closing,
Quicksilver shall, at its sole option, elect to either:

 

(i)                                     subject
to the Individual Title Defect Threshold and the Aggregate Deductible, reduce
the Initial Consideration by an amount 
determined pursuant to Sections 6.12(f), 6.12(h) and 6.12(i) as
being the value of such Title Defect (the “Title Defect Amount”);
or

 

(ii)                                  retain
the entirety of the Title Defect Property that is subject to such Title Defect
in which event the Initial Consideration shall be reduced by an amount equal to
the Preliminary Allocated Value of such Title Defect Property; or

 

(iii)                               provide
BreitBurn with an indemnity (the terms of such indemnity to be reasonably
satisfactory to BreitBurn) for such Title Defect under the Title Indemnity
Agreement (but in no case shall Quicksilver’s liability with regard thereto
exceed the Preliminary Allocated Value for the applicable Title Defect
Property), in which case the Title Defect Property shall be sold to BreitBurn
at Closing with no adjustment to the Initial Consideration; or

 

(iv)                              if
applicable, terminate this Agreement pursuant to Section 8.1(c).

 

(e)                                  Remedies for Title Benefits. Subject to Section 6.12(h),
with respect to each Well, well location or Oil and Gas Property (and the
applicable zone(s) therein) and/or other Acquired Assets affected by Title
Benefits reported under Section 6.12(a) or Section 6.12(b), the Initial Consideration
shall be increased by an amount equal to the increase in the Preliminary
Allocated Value for such Wells and well locations (and the applicable zone(s)
therein) and/or other Acquired Assets caused by such Title Benefits, as
determined pursuant to Section 6.12(g), 6.12(h) and
6.12(i) (the “Title
Benefit Amount”).

 

(f)                                    Title Defect Amount. The Title Defect Amount for any
applicable Title Defect shall be determined in accordance with the following
terms and conditions:

 

(i)                                     if
BreitBurn and Quicksilver agree on the Title Defect Amount, then that amount
shall be the Title Defect Amount;

 

(ii)                                  if
the Title Defect is a Lien or encumbrance that is undisputed and liquidated in
amount, then the Title Defect Amount shall be the amount necessary

 

56

 

to be paid to
remove the Title Defect from the Title Defect Property, not to exceed, however,
the Preliminary Allocated Value thereof;

 

(iii)                               if
the Title Defect represents a discrepancy between (1) the Net Revenue
Interest for any Title Defect Property and (2) the Net Revenue Interest
for such property as stated in Exhibit A-1,
then the Title Defect Amount shall be the product of the Preliminary Allocated
Value of such Title Defect Property multiplied by a fraction, the numerator of
which is the decreased Net Revenue Interest and the denominator of which is the
Net Revenue Interest stated in Exhibit A-1
therefor;

 

(iv)                              if
the Title Defect results from the failure to own a valid right to use the land
on which a portion of the Fixed Facilities is located, the Title Defect Amount
with respect to such Title Defect shall be the lesser of the cost per rod (or
per acre in the case of tracts outside the pipeline right-of-way) prevailing in
the area of such portion of the Fixed Facilities for the acquisition of
easements, rights-of-way, surface leases, fee parcels or licenses covering such
land that are similar to those on which the adjacent Fixed Facilities are
located or the actual acquisition cost paid by BreitBurn, a Acquired Company or
their respective Affiliate for such similar easements, rights-of-way, surface
leases, fee parcels or licenses covering such land;

 

(v)                                 if
the Title Defect represents an obligation or encumbrance upon or other defect
in title to the Title Defect Property of a type not described above, the Title
Defect Amount shall be determined by taking into account the Preliminary
Allocated Value of the Title Defect Property, the portion of the Title Defect
Property affected by the Title Defect, the legal effect of the Title Defect,
the potential economic effect of the Title Defect over the life of the Title
Defect Property, the values placed upon the Title Defect by BreitBurn and
Quicksilver and such other reasonable factors as are necessary to make a proper
evaluation, not to exceed, however, the Preliminary Allocated Value thereof;

 

(vi)                              the
Title Defect Amount with respect to a Title Defect Property shall be determined
without duplication of any costs or losses included in any other Title Defect
Amount hereunder; and

 

(vii)                           notwithstanding
anything to the contrary in this Section 6.12,
the aggregate Title Defect Amounts attributable to the effects of all Title
Defects upon any Title Defect Property shall not exceed the Preliminary
Allocated Value of the Title Defect Property.

 

(g)                                 Title Benefit Amount. The Title Benefit Amount resulting
from a Title Benefit shall be determined in accordance with the following
methodology, terms and conditions:

 

(i)                                     if
BreitBurn and Quicksilver agree on the Title Benefit Amount, then that amount
shall be the Title Benefit Amount;

 

57

 

(ii)                                  if
the Title Benefit represents a discrepancy between (1) the Net Revenue
Interest for any Well or well location (or the specified zone(s) therein) and (2) the
Net Revenue Interest stated in Exhibit A-1,
then the Title Benefit Amount shall be the product of the Preliminary Allocated
Value of the affected Well or well location (or the specified zone(s) therein)
multiplied by a fraction, the numerator of which is the increased Net Revenue
Interest and the denominator of which is the Net Revenue Interest stated in Exhibit A-1; and

 

(iii)                               if
the Title Benefit represents a decrease in the Working Interest stated in Exhibit A-1, the Title Benefit Amount shall
be determined by taking into account the Preliminary Allocated Value of the
property affected thereby, the portion of such property affected by the Title
Benefit, the legal effect of the Title Benefit, the potential economic effect
of the Title Benefit over the life of such property, the values placed upon the
Title Benefit by BreitBurn and Quicksilver and such other reasonable factors as
are necessary to make a proper evaluation.

 

(h)                                 Individual Title Defect Thresholds; Aggregate Deductible. Notwithstanding
anything stated herein to the contrary and subject to the overall cap provided
in this Section 6.12(h), (i) in no event shall there be any
adjustments to the Initial Consideration or other remedies provided by
Quicksilver for any individual Title Defect for which the Title Defect Amount
does not exceed the Individual
Title Defect Threshold (nor shall there be an adjustment
for any individual Title Benefit for which the Title Benefit Amount does not
exceed an amount equal to the Individual
Title Defect Threshold); and (ii) in no event shall
there be any adjustments to the Initial Consideration or other remedies
provided by Quicksilver for those Title Defects that exceed the Individual
Title Defect Threshold (each, a “Material Title Claim”, and collectively,
“Material Title Claims”) unless the sum of all of the Material Title
Claims plus all of the Material Environmental Claims exceeds the Aggregate
Deductible, and after which point BreitBurn shall only be entitled to
adjustments to the Initial Consideration to the extent that the sum of (A) the
aggregate Title Defect Amounts for all Material Title Claims plus (B) the
aggregate Environmental Defect Amounts for all Material Environmental Claims
exceeds the Aggregate Deductible. Material Title Claims shall not include any
Title Defect that is cured by Quicksilver. Similarly, Quicksilver shall be
entitled to an upward adjustment to the Initial Consideration for Title
Benefits only to the extent that the sum of those Title Benefit Amounts which,
individually, exceed the Individual Title Defect Threshold, exceeds an amount
equal to the Aggregate Deductible. NOTWITHSTANDING ANYTHING
TO THE CONTRARY CONTAINED IN THIS AGREEMENT, THE AGGREGATE AMOUNT OF ALL
REMEDIES PROVIDED BY QUICKSILVER FOR ANY TITLE DEFECTS AND ENVIRONMENTAL
DEFECTS, INCLUDING ALL DOWNWARD ADJUSTMENTS TO THE INITIAL CONSIDERATION FOR
TITLE DEFECTS AND ENVIRONMENTAL DEFECTS IN ACCORDANCE WITH THE PROVISIONS OF
THIS SECTION 6.12 AND SECTION 6.14, SHALL NOT EXCEED AN
AMOUNT EQUAL TO $145,000,000.

 

(i)                                     Title Dispute Resolution. Quicksilver and BreitBurn shall
attempt to agree on all Title Defects, Title Benefits, Title Defect Amounts and
Title Benefit Amounts prior to Closing. If Quicksilver and BreitBurn are unable
to agree by Closing, (1) all Title Defects, Title Benefits, Title Defect
Amounts and Title Benefit Amounts in dispute shall be exclusively and finally
resolved pursuant to this Section 6.12(i), (2) there shall be
no reduction or increase in the

 

58

 

Initial
Consideration at Closing with respect to the Title Defects, Title Benefits,
Title Defect Amounts and/or Title Benefit Amounts in dispute, and (3) all
adjustments and payments, if any, with respect thereto following Closing shall
be made pursuant to this Section 6.12.(i). There shall be a single
arbitrator, who shall be a title attorney with at least ten (10) years
experience in oil and gas title and who shall not have performed professional
services for either Party or any of their respective Affiliates during the
previous five years, as selected by mutual agreement of BreitBurn and
Quicksilver within fifteen (15) days after the end of the Cure Period, and
absent such agreement, by the Dallas office of the American Arbitration
Association (the “Title
Arbitrator”). The arbitration proceeding shall be
held in Dallas, Texas and shall be conducted in accordance with the Commercial
Arbitration Rules of the American Arbitration Association, to the extent
such rules do not conflict with the terms of this Article. The Title
Arbitrator’s determination shall be made within twenty (20) days after
submission of the matters in dispute and shall be final and binding upon both
Parties, without right of appeal. In making his determination, the Title Arbitrator
shall be bound by the rules set forth in this Section 6.12
and, subject to the foregoing, may consider such other matters as in the
opinion of the Title Arbitrator are necessary to make a proper determination. The
Title Arbitrator, however, may not award BreitBurn a greater Title Defect
Amount than the Title Defect Amount claimed by BreitBurn in its applicable
Title Defect Notice (or an amount that would be greater than the applicable
Preliminary Allocated Value) and may not award Quicksilver a greater Title
Benefit Amount than the Title Benefit Amount claimed by Quicksilver in its
applicable Title Benefit Notice. The Title Arbitrator shall act as an expert
for the limited purpose of determining the specific disputed Title Defect,
Title Benefit, Title Defect Amounts and/or Title Benefit Amounts submitted by
either Party and may not award damages, interest or penalties to either
Party with respect to any matter. Quicksilver and BreitBurn shall bear their
respective legal fees and other costs of presenting the case. Each of
Quicksilver and BreitBurn shall bear one-half of the costs and expenses of the
Title Arbitrator. To the extent that the award of the Title Arbitrator with
respect to any Title Defect Amount or Title Benefit Amount is not taken into
account as an adjustment to the Initial Consideration pursuant to Section 6.12, then within ten (10) days
after the Title Arbitrator delivers written notice to BreitBurn and Quicksilver
of his award with respect to a Title Defect Amount or a Title Benefit Amount, (i) BreitBurn
shall pay to Quicksilver the amount, if any, so awarded by the Title Arbitrator
to Quicksilver and (ii) Quicksilver shall pay to BreitBurn the amount, if
any, so awarded by the Title Arbitrator to BreitBurn.

 

(j)                                     General Disclaimer of Title Warranties and Representations. Except
for BreitBurn’s remedies for Title Defects set forth in this Section 6.12
and except to the extent provided in Section 4.21, Quicksilver
makes no warranty or representation, express, implied, statutory or otherwise,
with respect to Quicksilver’s title to any of the QRI Assets (or the Acquired
Companies’ title to any of the other Acquired Assets) and BreitBurn hereby
acknowledges and agrees that BreitBurn’s sole remedy for any (x) breach of the
representation set forth in Section 4.21 shall be as set forth in Section 9.2(a)(i),
and (y) defect of title, including any Title Defect, with respect to any of the
Acquired Assets shall be as set forth in Section 6.12. No
warranty of title shall be contained in the Asset Assignments.

 

(k)                                  Exclusive Remedy. SECTION 6.12
SHALL BE THE EXCLUSIVE RIGHT AND REMEDY OF BREITBURN WITH RESPECT TO
QUICKSILVER’S (OR THE ACQUIRED COMPANIES’) FAILURE TO HAVE DEFENSIBLE TITLE
WITH RESPECT TO ANY OF THE ACQUIRED ASSETS; PROVIDED, HOWEVER,

 

59

 

BREITBURN
SHALL HAVE THE RIGHTS UNDER SECTION 9.2(a)(i) FOR THE PERIOD
SET FORTH IN SECTION 9.1(a) WITH RESPECT TO A BREACH OF THE
WARRANTY SET FORTH IN SECTION 4.21.

 

Section 6.13                                Preferential
Purchase Rights.

 

(a)                                  Preferential Purchase Right Procedures. With respect to any
preferential purchase right pertaining to any of the Interests that would be
triggered by the transactions contemplated hereby (each, a “Preferential
Purchase Right”), Quicksilver shall send, within ten (10) Business
Days following the execution of this Agreement, to the holder of each such
right a written notice, in material compliance with the contractual provisions
applicable to such Preferential Purchase Right.

 

(b)                                 Exercise of Preferential Rights. If, prior to Closing, any
holder of a Preferential Purchase Right notifies Quicksilver that it intends to
consummate the purchase of any part of the Interests and/or Acquired
Assets to which its Preferential Purchase Right applies (in such case, a “Preferential
Right Property”), that Preferential Right Property shall be excluded from
the Interests to be assigned and sold to BreitBurn hereunder, and the Initial
Consideration shall be reduced by the Preliminary Allocated Value of the
excluded Preferential Right Property. Quicksilver shall be entitled to all
proceeds from the holder of a Preferential Purchase Right who exercises its
right to purchase a Preferential Right Property prior to Closing. If the holder
of such Preferential Right Property thereafter fails to consummate the purchase
of the Preferential Right Property covered by such right on or before sixty
(60) days following the Closing Date, then Quicksilver may notify
BreitBurn, and BreitBurn, if notified, shall purchase, on or before ten (10) Business
Days following receipt of such notice, the Preferential Right Property from
Quicksilver, under the terms of this Agreement for a price equal to the
Preliminary Allocated Value of the applicable Preferential Right Property (as
the same may be otherwise adjusted in accordance with the terms hereof).

 

(c)                                  Expiration of Election Periods; Post-Closing. If by Closing
a Preferential Purchase Right burdening any Preferential Right Property has not
been exercised, the time for exercising such Preferential Purchase Right has
not expired and such Preferential Purchase Right has not been waived, then that
Preferential Right Property shall be excluded from the Interests to be assigned
and sold to BreitBurn hereunder, and the Initial Consideration shall be reduced
by the Preliminary Allocated Value of such excluded Preferential Right Property.
If the time for the exercise of the Preferential Purchase Right with respect to
any excluded Preferential Right Property described in this Section 6.13(c) expires
following the Closing without the exercise of such Preferential Purchase Right
by the holder thereof or such Preferential Purchase Right is waived, then
Quicksilver may notify BreitBurn, and BreitBurn, if notified, shall
purchase, on or before ten (10) Business Days following receipt of such
notice, such Preferential Right Property from Quicksilver, under the terms of
this Agreement for a price equal to the Preliminary Allocated Value of such
Preferential Right Property (as the same may be otherwise adjusted in
accordance with the terms hereof; provided, in no event shall BreitBurn have
any obligation to purchase any such Preferential Right Property pursuant to
this Section 6.13(c) after 90 days following the Closing Date,
unless BreitBurn has failed to comply with its obligations under this Section 6.13(c) to
purchase such Preferential Right Property during such 90-day period following
the Closing Date). All Preferential Right Properties for which applicable
Preferential

 

60

 

Purchase
Rights have been waived prior to Closing, or as to which the period to exercise
such right has expired prior to Closing, shall be sold to BreitBurn at Closing
pursuant to the provisions of this Agreement.

 

Section 6.14                                Environmental
Defects; Environmental Defect Procedure and Adjustments.

 

(a)                                  Environmental Assessment. Upon notice to Quicksilver,
BreitBurn shall, subject to the provisions of Section 6.4(a) and
this Section 6.14(a), have the right to conduct an environmental
assessment of all or any portion of the Acquired Assets (the “Environmental
Assessment”) to be conducted by a reputable environmental consulting or
engineering firm approved in advance in writing by Quicksilver but only to the
extent that Quicksilver may grant such right without violating any
obligations to any third party. The Environmental Assessment shall be conducted
at the sole cost, risk and expense of BreitBurn, and shall be subject to the
indemnity provisions of Section 6.4(a) and Section 9.3.
Prior to conducting any sampling, boring, drilling or other invasive
investigative activity with respect to the Acquired Assets (“Invasive
Activity”), BreitBurn shall furnish for Quicksilver’s review a proposed
scope of such Invasive Activity, including a description of the activities to
be conducted and a description of the approximate locations of such activities.
Any Invasive Activity shall be subject to the prior written approval of
Quicksilver, and Quicksilver may require reasonable modifications of the
proposed Invasive Activity as a condition of such approval. Quicksilver shall
have the right to be present during any Environmental Assessment of the
Acquired Assets and shall have the right, at its option and expense, to split
samples with BreitBurn. After completing any Environmental Assessment of the
Acquired Assets, BreitBurn shall, at its sole cost and expense, restore the
Acquired Assets to approximately their original condition prior to the
commencement of such Environmental Assessment, unless Quicksilver agrees that
such restoration is unnecessary, and shall promptly dispose of all drill
cuttings, corings, or other investigative-derived wastes generated in the
course of the Environmental Assessment. BreitBurn shall maintain, and shall
cause its officers, employees, representatives, consultants and advisors to
maintain, all information obtained by BreitBurn pursuant to any Environmental
Assessment or other due diligence activity as strictly confidential prior to
Closing or in perpetuity if Closing does not occur, unless disclosure of any
facts discovered through such Environmental Assessment is required under any
Environmental Laws. BreitBurn shall provide Quicksilver with a copy of the
final draft of all environmental reports prepared by, or on behalf of,
BreitBurn with respect to any Environmental Assessment or Invasive Activity
conducted on the Acquired Assets. In the event that any necessary disclosures
under applicable Environmental Laws are required prior to Closing with respect
to matters discovered by any Environmental Assessment conducted by, for or on
behalf of BreitBurn, BreitBurn agrees that Quicksilver shall be the responsible
party for disclosing such matters to the appropriate Governmental Entities.

 

(b)                                 Environmental Defects.

 

(i)                                     If,
as a result of its investigation pursuant to Section 6.14(a),
BreitBurn determines that with respect to the Acquired Assets, there exists an
Environmental Condition (other than with respect to asbestos, asbestos
containing materials or NORM, and excluding any matter set forth on Schedule 4.13)
(in each case, an “Environmental Defect”), then on or prior to the Title
Claim Date,

 

61

 

BreitBurn may give
Quicksilver a written notice of such Environmental Defect that sets forth the information
required by this Section 6.14(b) (an “Environmental Defect
Notice”). For all purposes of this Agreement, BreitBurn shall be deemed to
have waived any Environmental Defect which BreitBurn fails to timely and
properly assert as an Environmental Defect by an Environmental Defect Notice
received by Quicksilver on or before the Title Claim Date. To be effective, an
Environmental Defect Notice must set forth (i) a description of the matter
constituting the alleged Environmental Defect, (ii) a description of each
Acquired Asset (or portion thereof) affected by the alleged Environmental
Defect, (iii) the proportionate share attributable to the Acquired Assets
of the estimated Lowest Cost Response to eliminate the alleged Environmental
Defect (the “Environmental Defect Amount”), and (iv) supporting
documents reasonably necessary for Quicksilver to verify the existence of the
alleged Environmental Defect and the Environmental Defect Amount. BreitBurn
shall furnish Quicksilver once every two (2) weeks from and after the date
hereof until the Title Claim Date with Environmental Defect Notices with
respect to any Environmental Defects that any employee or representative of
BreitBurn discovers or becomes aware of during such two (2) week period.

 

(ii)                                  Quicksilver
shall have the right, but not the obligation, to attempt, at its sole cost, to
cure or remediate at any time prior to Closing any Environmental Defects of
which it has been advised by BreitBurn pursuant to an Environmental Defect
Notice delivered before the Title Claim Date.

 

(iii)                               In
the event that any Environmental Defect asserted by BreitBurn pursuant to an
Environmental Defect Notice delivered before the Title Claim Date is not waived
by BreitBurn or cured on or before the Closing Date, Quicksilver shall, at its
sole election, elect (at the Closing, for Environmental Defects with respect to
which no dispute exists) to do one of the following:

 

(1)                                  subject
to the Individual Environmental Defect Threshold and Aggregate Deductible,
reduce the Initial Consideration by the amount of the Environmental Defect
Amount relating to such Environmental Defect as agreed upon by Quicksilver and
BreitBurn or determined pursuant to Section 6.14(b)(v);

 

(2)                                  provided
that the Parties shall have agreed to the general plan of remediation with
respect to such Environmental Defect and the time period by which such
remediation shall take place, cure such Environmental Defect after Closing;

 

(3)                                  if
such Environmental Defect can be cured by paying a fine or penalty, Quicksilver
may cure such Environmental Defect by electing to pay such fine or
penalty; or

 

(4)                                  if
applicable, terminate this Agreement pursuant to Section 8.1(c).

 

62

 

(iv)                              Section 6.14(b)(iii) shall
be the exclusive right and remedy of BreitBurn with respect to Environmental
Defects asserted by BreitBurn pursuant to Section 6.14(b)(i).

 

(v)                                 Prior
to Closing, Quicksilver and BreitBurn shall attempt to agree on all
Environmental Defects and Environmental Defect Amounts that are the subject of
timely and properly asserted Environmental Defect Notices. If Quicksilver and
BreitBurn are unable to agree by Closing, (1) all Environmental Defects
and/or Environmental Defect Amounts in dispute shall be exclusively and finally
resolved by arbitration pursuant to this Section 6.14(b)(v), (2) there
shall be no reduction in the Initial Consideration at Closing with respect to
the Environmental Defects and/or Environmental Defect Amounts in dispute, and (3) all
adjustments and payments, if any, with respect thereto following Closing shall
be made pursuant to this Section 6.14(b)(v). The arbitrator shall
be an environmental consultant approved in writing by Quicksilver and BreitBurn
who is experienced in environmental corrective action at oil and gas properties
in the relevant jurisdiction and who shall not have performed professional
services for either Party or any of their respective Affiliates during the
previous five years, as selected by mutual agreement of BreitBurn and
Quicksilver within fifteen (15) days after the end of the Cure Period, and
absent such agreement, by the Dallas office of the American Arbitration
Association (the “Independent Expert”). The arbitration proceeding shall
be held in Dallas, Texas and shall be conducted in accordance with the
Commercial Arbitration Rules of the American Arbitration Association, to
the extent such rules do not conflict with the terms of this Section. The
Independent Expert’s determination shall be made within twenty (20) days after
submission of the matters in dispute and shall be final and binding upon both
Parties, without right of appeal. In making his determination, the Independent
Expert shall be bound by the rules set forth in this Section 6.14
and, subject to the foregoing, may consider such matters as in the opinion
of the Independent Expert are necessary or helpful to make a proper
determination. Additionally, the Independent Expert may consult with and
engage disinterested third parties to advise the Independent Expert. The
Independent Expert, however, may not award BreitBurn a greater
Environmental Defect Amount than the Environmental Defect Amount claimed by
BreitBurn in its applicable Environmental Defect Notice. The Independent Expert
shall act as an expert for the limited purpose of determining the specific
disputed Environmental Defects and/or Environmental Defect Amounts submitted by
either Party pursuant to this Section 6.14(b)(v) and may not
award damages, interest or penalties to either Party with respect to any matter.
Quicksilver and BreitBurn shall each bear its own legal fees and other costs of
presenting its case to the Independent Expert. Each Party shall bear one-half
of the costs and expenses of the Independent Expert. To the extent that the
award of the Independent Expert with respect to any Environmental Defect Amount
is not taken into account as an adjustment to the Initial Consideration at
Closing pursuant to this Section 6.14, then within ten (10) days
after the Independent Expert delivers written notice to BreitBurn and
Quicksilver of his award with respect to an Environmental Defect Amount, (i) BreitBurn
shall pay to Quicksilver the amount, if any, so awarded by the Independent
Expert to

 

63

 

Quicksilver
and (ii) Quicksilver shall pay to BreitBurn the amount, if any, so awarded
by the Independent Expert to BreitBurn.

 

(vi)                              Notwithstanding
anything stated herein to the contrary and subject to the overall cap provided
in Section 6.12(h), (1) in no event shall there be any
adjustments to the Initial Consideration or other remedies provided by
Quicksilver for any individual Environmental Defect for which the Environmental
Defect Amount does not exceed $300,000 (the “Individual Environmental Defect
Threshold”); and (2) in no event shall there be any adjustments to the
Initial Consideration or other remedies provided by Quicksilver for those
Environmental Defects that exceed the Individual Environmental Defect Threshold
(each, a “Material Environmental Claim”, and collectively, “Material
Environmental Claims”) unless the sum of all of the Material Environmental
Claims plus all of the Material Title Claims exceeds the Aggregate Deductible,
and after which point BreitBurn shall only be entitled to adjustments to the
Initial Consideration to the extent that the sum of (A) the aggregate
Environmental Defect Amounts for all Material Environmental Claims plus (B) the
aggregate Title Defect Amounts for all Material Title Claims exceeds the
Aggregate Deductible. Material Environmental Claims shall not include any
Environmental Defect that Quicksilver elects to cure pursuant to Section 6.14(b)(iii)(2) or
Section 6.14(b)(iii)(3).

 

Section 6.15                                Historical
Financial Statements.

 

(a)                                  Quicksilver
shall use its commercially reasonable efforts to prepare, at the sole cost and
expense of BreitBurn, the financial statements required by the Securities and
Exchange Commission (“SEC”) (the “Special Financial Statements”),
that will be required of BreitBurn or any of its Affiliates by the SEC in connection
with reports, registration statements and other filings to be made by BreitBurn
or any of its Affiliates related to the transactions contemplated by this
Agreement with the SEC pursuant to the Securities Act, or the Exchange Act, in
such form that such statements and the notes thereto can be audited by
Deloitte & Touche LLP (“Quicksilver’s Auditor”). Quicksilver
(x) shall cooperate with and permit BreitBurn to reasonably participate in the
preparation of the Special Financial Statements and (y) shall provide BreitBurn
and its representatives with reasonable access to the personnel of Quicksilver
and its Affiliates who engage in the preparation of the Special Financial
Statements.

 

(b)                                 Quicksilver
shall execute and deliver or cause to be executed and delivered to Quicksilver’s
Auditor such representation letters, in form and substance customary for
representation letters provided to external audit firms by management of
Quicksilver (if the financial statements are the subject of an audit or are the
subject of a review pursuant to Statement of Accounting Standards 100 (Interim
Financial Information)), as may be reasonably requested by Quicksilver’s
Auditor, with respect to the Special Financial Statements. BreitBurn agrees
that (i) to the extent any such representation letter is delivered by
Quicksilver’s management, or on its behalf, BreitBurn shall indemnify and hold
harmless Quicksilver’s management and provide a defense for Quicksilver’s
management (INCLUDING, IN EACH CASE, WITH RESPECT TO
THEIR OWN NEGLIGENCE) with regard to the execution, delivery or any
other action related to the provision of such representation letters to the
same

 

64

 

extent as any
executive officer or director of BreitBurn would be indemnified had they
performed such action; (ii) BreitBurn shall provide a customary
representation letter to Quicksilver’s Auditor, if reasonably requested; and (iii) BreitBurn’s
existing outside auditors shall provide a customary representation letter to
Quicksilver’s Auditor, if reasonably requested.

 

(c)                                  Quicksilver
has engaged Quicksilver’s Auditor to perform an audit of the Special
Financial Statements and shall use commercially reasonable efforts to cause
Quicksilver’s Auditor to issue unqualified opinions with respect to the Special
Financial Statements (the Special Financial Statements and related audit
opinions being hereinafter referred to as the “Audited Special Financial
Statements”) and provide its written consent for the use of its audit reports
with respect to the Special Financial Statements in reports, registration
statements or other documents filed by BreitBurn or any of its Affiliates under
the Exchange Act or the Securities Act, as needed. BreitBurn shall reimburse
Quicksilver for all fees charged by Quicksilver’s Auditor with respect to the
preparation and delivery by Quicksilver’s Auditor to BreitBurn of the Audited
Special Financial Statements and any other fees charged by Quicksilver’s
Auditor to facilitate BreitBurn’s ongoing compliance with SEC rules and
regulations. Quicksilver shall take all reasonable action as may be
necessary to facilitate the completion of such audit and delivery of the
Audited Special Financial Statements to BreitBurn or any of its Affiliates as
soon as reasonably practicable, but no later than the Closing Date. BreitBurn
shall reimburse Quicksilver for all reasonable costs and expenses incurred by
Quicksilver in complying with this Section 6.15.

 

Section 6.16                                Operatorship.
Within ten (10) Business Days after execution of this Agreement,
Quicksilver shall send notices to all co-owners of the QRI Assets that it
currently operates indicating that it is resigning as operator contingent upon
and effective at Closing, and nominating and recommending BreitBurn (or, at
BreitBurn’s request, BreitBurn’s designated Affiliate under Section 11.3)
as successor operator, subject to and in reliance on BreitBurn’s
representations, warranties, covenants and agreements in this Section 6.16.
Quicksilver will, upon BreitBurn’s request, assist BreitBurn in its efforts to
succeed Quicksilver as operator of the applicable QRI Assets, but without being
obligated to pay any consideration or waive or release any right or privilege
as part of such assistance. BreitBurn shall promptly, following Closing,
file all appropriate forms, and declarations or bonds with federal and state
agencies relative to its assumption of operatorship if BreitBurn elects to
assume operatorship. For all Quicksilver-operated QRI Assets for which
BreitBurn wishes to assume operatorship, Quicksilver, subject to compliance
with all applicable operating agreements, shall execute and deliver to
BreitBurn at Closing and BreitBurn shall promptly file all the appropriate
forms with the applicable regulatory agency transferring operatorship of such
QRI Assets to BreitBurn. BreitBurn represents and warrants to, and covenants
and agrees with Quicksilver, that BreitBurn (or any Affiliate of BreitBurn that
BreitBurn requests be nominated and recommended as successor operator pursuant
to this Section 6.16), as applicable, is qualified and has the
operational capability to succeed Quicksilver as operator and conduct
operations to at least the same standard as Quicksilver in accordance with the
terms of the applicable operating agreement (or before assuming such
operatorship will be so qualified and have such operational capacity).

 

Section 6.17                                Cash
Items. After Closing, all proceeds, accounts receivable, notes receivable,
income, revenues, monies and other items included in or attributable to the
Excluded Assets and all other Excluded Assets shall belong to and be paid over
to Quicksilver, and all

 

65

 

proceeds, accounts receivable, notes receivable, income, revenues,
monies and other items included in or attributable to the QRI Assets with
respect to any period of time after the Effective Time shall belong to and be
paid over to BreitBurn, subject, in each case, to the adjustments provided in Sections
2.5(c) and 2.6.

 

Section 6.18                                Standstill. Each Party agrees that, so long as the other Party is not in material
breach of the terms of this Agreement, such Party will not, and will cause each
of its Affiliates and their respective officers, directors, managers, partners,
employees, agents or representatives (including any financial or legal advisors
or other representatives) not to, directly or indirectly, (a) solicit, initiate
or facilitate (by way of furnishing information) any inquiries or proposals
regarding any transaction involving, or in any way relating to, the sale of the
Acquired Companies and/or the sale of all or substantially all of the Acquired
Assets other than the transactions contemplated by this Agreement (a “Competing
Transaction”), (b) participate in discussions or negotiations regarding, or
furnish to any Person any information in connection with, a Competing
Transaction, or (c) enter into any agreement regarding any Competing
Transaction.

 

Section 6.19                                Release. On or before Closing, Quicksilver shall cause (a) the Acquired
Companies to be released from any obligations in respect of the Disclosed
Contracts listed in item 1 and item 2 of Schedule 4.8 and (b) any Liens
encumbering any of the Interests that secure the payment of Long Term Debt or
any other indebtedness for borrowed money to be released.

 

Section 6.20                                Quicksilver Lock-Up. Without the prior written consent of
BreitBurn, Quicksilver agrees that it will not effect a sale or distribution of
any of the Common Units comprising the Equity Consideration prior to the first
anniversary of the Closing Date (the “Lock-Up Date”). From and after the
Lock-Up Date and until eighteen (18) months after the Closing Date, Quicksilver
may sell up to fifty percent (50%) of the Common Units comprising the Equity
Consideration. Quicksilver shall be free to sell all or any portion of the
Common Units comprising the Equity Consideration after eighteen (18) months
from the Closing Date. Notwithstanding the prohibitions in this Section 6.20,
Quicksilver may at any time: (a) transfer the Common Units comprising the
Equity Consideration to an Affiliate of Quicksilver (provided that such
Affiliate agrees to the restrictions in this Section 6.20); and (b)
pledge or grant a security interest in the Common Units comprising the Equity
Consideration (provided such pledgee agrees to the restrictions in this Section 6.20),
and any pledgee of such Common Units shall be permitted to transfer the Common
Units in connection with any exercise of its rights against Quicksilver or any
of its Affiliates (provided that the transferee agrees to the restrictions in
this Section 6.20).

 

Section 6.21                                Redemption Prohibition. BreitBurn shall not, and shall cause its
Affiliates (including BreitBurn Parent) not to, repurchase or redeem Common
Units or take any other action that would cause Quicksilver to own fifty
percent (50%) or more of the outstanding limited partner interests of BreitBurn
Parent.

 

Section 6.22                                Consent. BreitBurn shall obtain the consent required pursuant to the document
listed under item 1 of Schedule 5.4(a).

 

66

 

Section 6.23                                End
User Contracts.

 

(a)                                  If
any of the Contracts provide for the sale of Hydrocarbons by Quicksilver or any
of its Affiliates to a Person who is using such Hydrocarbons rather than acting
as a reseller or marketer of such Hydrocarbons (the “End User Contracts”),
then the following provisions of this Section 6.23 shall apply.

 

(b)                                 Quicksilver
and BreitBurn shall use commercially reasonable efforts to identify all End
User Contracts within twenty five (25) days after the date of this Agreement. Each
Party shall notify the other of those Contracts which it has identified as End
User Contracts.

 

(c)                                  Breitburn
may notify Quicksilver of its election to include any one or more of the End
User Contracts identified and notified by either Party pursuant to clause (b)
above in the Excluded Assets, in which case such End User Contracts shall be
deemed part of the Excluded Assets (the “Subject Contracts”). The
aforesaid notice shall be given by BreitBurn to Quicksilver within thirty (30)
days after the date of this Agreement. Any End User Contracts not included in
Excluded Assets pursuant to such notice shall remain part of the Acquired
Assets. If any Subject Contract is held by an Affiliate of Quicksilver, then
such Subject Contract shall be assigned by such Affiliate to Quicksilver, to
the extent such Subject Contract is assignable, prior to the Closing.

 

(d)                                 As
to each Subject Contract, at Closing BreitBurn and Quicksilver shall enter into
an agreement whereby BreitBurn agrees to (i) sell to Quicksilver the volumes of
Hydrocarbons covered by such Subject Contract on the same terms and conditions
that are contained in such Subject Contract; provided, the sales price to
Quicksilver for each MMBtu or other applicable unit of measure shall be the
MMBtu price or other unit price applicable under the Subject Contract less
$0.02 mcfe and (ii) provide everything necessary and perform every action
necessary (other than nomination, scheduling and marketing services that shall
be provided by Quicksilver at its sole cost and expense), including, without
limitation, providing transportation, at BreitBurn’s sole cost and expense, for
Quicksilver to comply in all respects with its obligations under such Subject
Contract. By way of clarification, BreitBurn shall have the same termination
and non-renewal rights that Quicksilver or its Affiliate have under the Subject
Contract and applicable law. BreitBurn acknowledges and agrees that Quicksilver
shall have the right to terminate any of the Subject Contracts as provided
therein and shall have no obligation to extend or renew any of the Subject
Contracts.

 

(e)                                  Following
the Closing, BreitBurn may notify Quicksilver of its election to accept the
assignment of any one or more of the Subject Contracts, in which case
Quicksilver shall assign such Subject Contracts to BreitBurn (without recourse,
representation or warranty by Quicksilver but free and clear of any Liens
created by, through or under Quicksilver encumbering such Subject Contracts
other than Permitted Liens), subject to obtaining any required consent from the
counterparty under such Subject Contracts. Any Subject Contract so assigned by
Quicksilver to BreitBurn pursuant to this Section 6.23(d) shall
automatically be deemed to be an Acquired Asset.

aggregate, plus (ii) the downward adjustments to the Initial Consideration on
account for Environmental Defects in accordance with the provisions of Section
6.14 equals or exceeds $145,000,000; provided, however,
that if BreitBurn and Quicksilver have not agreed upon the aforesaid downward
adjustment in the Initial Consideration attributable to any Title Defect or
Environmental Defect, then the downward adjustment asserted by BreitBurn for
such Title Defect or Environmental Defect shall be used only for purposes of
determining Quicksilver’s right to terminate under this clause (c);

 

(d)                                 by
BreitBurn, if Quicksilver shall have breached or failed to perform in any
material respect any of its representations, warranties, covenants or other
agreements contained in this Agreement, which breach or failure to perform
would give rise to the failure of a condition set forth in Section 7.3; provided, however, that the breaching Party shall first be
entitled to ten (10) days’ notice and the opportunity to cure and provided furthermore that the Party seeking to so terminate
not be in breach at such time;

 

(e)                                  by
Quicksilver, if BreitBurn shall have breached or failed to perform in any
material respect any of its representations, warranties, covenants or other
agreements contained in this Agreement, which breach or failure to perform
would give rise to the failure of a condition set forth in Section 7.2; provided, however, that the breaching Party shall first be
entitled to ten (10) days’ notice and the opportunity to cure and provided furthermore that the Party seeking to so terminate
not be in breach at such time; or

 

(f)                                    by
either BreitBurn or Quicksilver if any Law or Order or rule becomes final and
effective, prohibiting or making illegal the consummation of the transactions
contemplated by this Agreement, upon notification to the non-terminating Party
by the terminating Party.

 

Section 8.2                                      Effect
of Termination.

 

(a)                                  In
the event of any termination of this Agreement as provided in Section 8.1,
this Agreement shall forthwith be of no further force and effect and, except
for the obligations regarding the Deposit (under Section 2.2), BreitBurn’s
indemnification obligations under Section 6.4(a)(iii), the Parties’
respective obligations under Section 11.2, and BreitBurn’s obligations
under the Confidentiality Agreement, all of which shall expressly survive the
termination of this Agreement, neither Party shall have any further obligation
or liability to the other with regard to this Agreement, the transactions
contemplated hereby, or the termination hereof except to the limited extent
provided in Section 2.2(b) and Section 8.2(b).

 

70

 

(b)                                 If
all conditions precedent to the obligations of Quicksilver to consummate the
transactions contemplated by this Agreement set forth in Article VII
have been met and this Agreement is terminated prior to Closing pursuant to Section
8.1(d) as a result of (i) Quicksilver’s breach of any of Quicksilver’s
representations and warranties contained in this Agreement or (ii) Quicksilver’s
(A) intentional failure to perform in any material respect any of the covenants
or agreements contained in Section 2.12 (assuming the conditions
precedent to the obligations of Quicksilver to consummate the transactions
contemplated by this Agreement set forth in Article VII have been met), Section
6.2(b), Section 6.15, Section 6.18 or Section 6.19 or
(B) intentional failure to perform in any material respect any remaining
material covenants or agreements contained in this Agreement which failure
(that is, a failure referenced in this clause (B)) is designed by Quicksilver
to cause one or more of the conditions to Closing set forth in Article VII
not to be met, and the collective failure to perform under clauses (A) and (B)
preceding results in Damages suffered by BreitBurn as a result of such
termination (including any costs resulting from the unwinding or termination of
any hedges or contingent hedges) of $72,500,000 or more, then notwithstanding
anything to the contrary in this Agreement, Breitburn, in addition to the
return of the Deposit, shall be entitled to recover from Quicksilver an amount
equal to the Damages BreitBurn suffers as a result of such termination
(including any costs resulting from the unwinding or termination of any hedges
or contingent hedges; and the Parties acknowledge and agree that any such costs
will constitute direct damages and thus are not covered by Section 11.13).

 

ARTICLE IX

SURVIVAL; INDEMNIFICATION

 

Section 9.1                                      Survival.

 

(a)                                  The
representations, warranties, covenants and agreements set forth in this
Agreement shall survive Closing and the delivery of the Asset Assignments, the
Venture Assignments and any other Closing documents; provided,
however, that (i) except as provided in clause (ii) below, and
except for representations and warranties made in Section 4.11 with
respect to Taxes, which are addressed in Article X, the representations
and warranties made in Article III and Article IV and any
corresponding representations and warranties made in any certificate delivered
by or on behalf of Quicksilver at Closing pursuant to Section 2.12
(as well as any indemnification obligations or liabilities therefor) shall only
survive until the date that is nine (9) months following the Closing Date, (ii)
the representations and warranties made in Section 4.13, Section
4.18(d) or in any certificates or documents relating thereto delivered in
connection with this Agreement shall terminate as of the Closing Date (and
Quicksilver shall not have any indemnification obligations or liabilities
therefor), (iii) except as provided in clause (i) above, the representations
and warranties, if any, made by Quicksilver in any certificates or documents
delivered in connection with this Agreement shall terminate as of the Closing
Date (and Quicksilver shall not have any indemnification obligations or
liabilities therefor), (iv) all covenants and agreements set forth in Section 6.1
(as well as any indemnification obligations or liabilities therefor) shall only
survive until the date that is nine (9) months following the Closing Date, and
(v) all covenants and agreements of Quicksilver contemplated to be complied
with or performed prior to the Closing (as well as any indemnification
obligations or liabilities therefor) shall only survive until the date that is
nine (9) months following the Closing Date. The survival

 

71

 

period set forth above for each
representation, warranty, covenant or agreement is referred to herein as the “Survival
Period.”

 

(b)                                 No
Action for Damages or other relief of any kind (including an Action under Section 9.2(a)
or Section 9.3(a)) arising out of or relating to any breach of
representation, warranty, covenant or agreement under this Agreement or in any
certificate or documents delivered in connection with this Agreement may be
brought unless a written notice describing the nature of the Action, the theory
of liability or the nature of the relief sought and the material factual
assertions upon which the Action is based (a “Claim Notice”) is given to
the other Party before the termination of the applicable Survival Period. Notwithstanding
anything herein to the contrary, a claim for a breach of any representation,
warranty, covenant or agreement that would otherwise terminate shall continue
to survive for any Damages with respect to which a Claim Notice is given
pursuant to this Agreement prior to the end of the applicable Survival Period,
until such claim is finally resolved and all related Damages are paid, subject
to the limitations and restrictions set forth herein, and any such Claim Notice
made as to Damages that may also be recoverable from third parties or insurance
pursued by BreitBurn as contemplated in Section 9.4 below shall
nevertheless be valid Damages for purposes of tolling the applicable Survival
Period notwithstanding the pendency of any such potential recoveries.

 

Section 9.2                                      Indemnification
by Quicksilver.

 

(a)                                  General Indemnity from Quicksilver. Except as otherwise
provided in Article X and subject to the further provisions hereof, if
Closing occurs, then upon, from and after Closing Quicksilver shall DEFEND, INDEMNIFY AND HOLD HARMLESS BreitBurn, the Acquired
Companies and their respective successors and permitted assigns and their
respective shareholders, members, partners (general and limited), officers,
directors, managers, employees (other than the Business Employees and any other
employee of Quicksilver relating to the QRI Assets), agents and representatives
and each of their heirs, executors, successors and assigns (collectively, the “BreitBurn
Indemnified Parties”), from and against and in respect of any and all
Damages, which arise out of (i) any breach of any of the representations
and warranties (other than those which do not survive the Closing as stated in Section
9.1(a)) made in Article III, Article IV (other than
representations and warranties made in Section 4.11 with respect to
Taxes, which are addressed in Article X), or any corresponding
representations and warranties made in any certificate delivered by or on
behalf of Quicksilver at Closing pursuant to Section 2.12, (ii) any
breach of any of the covenants of Quicksilver in this Agreement, or
(iii) the Retained Liabilities.

 

(b)                                 Limitations on Quicksilver’s Indemnity Obligations. The
obligation to indemnify BreitBurn Indemnified Parties set forth in Section 9.2(a)
shall be subject to each of the following limitations:

 

(i)                                     Quicksilver’s
indemnification obligations under Section 9.2(a)(i) as to breach of
a particular representation or warranty shall terminate upon expiration of the
respective Survival Period, except as set forth in Section 9.1(b).

 

72

 

(ii)                                  Excluding
the Retained Liabilities, any individual indemnification claim for Damages
asserted by BreitBurn or any other BreitBurn Indemnified Parties under this Section
9.2 must equal or exceed the sum of $1,000,000 (“De Minimis BreitBurn
Losses”); and any such individual indemnification claim for Damages
asserted by BreitBurn or any BreitBurn Indemnified Parties that does not meet
or exceed the De Minimis BreitBurn Losses shall be excluded in their entirety,
and Quicksilver, shall have no liability hereunder to BreitBurn or any other
BreitBurn Indemnified Parties for any such individual indemnification claim for
Damages that does not meet or exceed the De Minimis BreitBurn Losses;

 

(iii)                               To
the extent that BreitBurn or BreitBurn Indemnified Parties timely and properly
assert indemnification claims for Damages which individually meet or exceed the
De Minimis BreitBurn Losses (each, a “Material Claim”, and,
collectively, the “Material Claims”), Quicksilver shall have no
indemnification, reimbursement or payment obligations for any Damages pursuant
to this Section 9.2, unless and until, and then only to the extent, the
cumulative aggregate amount of all Material Claims exceed $45,000,000 (“Quicksilver’s
Deductible”), after which point, Quicksilver shall only be liable for the
amount by which such Material Claims exceed Quicksilver’s Deductible, subject
to the further limitations set forth in Sections 9.2(b)(iv) and Section
9.2(b)(v); provided, the preceding provisions of this subsection (iii)
shall not apply to Retained Liabilities.

 

(iv)                              The
limitations described in Section 1.3 above; and

 

(v)                                 NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS AGREEMENT
BUT SUBJECT TO SECTION 8.2(b), QUICKSILVER’S AGGREGATE LIABILITY TO
BREITBURN AND ANY BREITBURN INDEMNIFIED PARTIES FOR ALL ACTIONS OR DAMAGES
UNDER OR RELATING TO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY,
INCLUDING WITH RESPECT TO THE INDEMNIFICATION PROVISIONS SET FORTH IN THIS ARTICLE IX
OR ANY APPLICABLE PROVISIONS OF ARTICLE X, OR ANY BREACH BY
QUICKSILVER OF THIS AGREEMENT, SHALL NOT EXCEED AN AMOUNT EQUAL TO (i)
$145,000,000 LESS (ii) THE AGGREGATE AMOUNT OF ALL DOWNWARD ADJUSTMENTS TO THE
INITIAL CONSIDERATION FOR TITLE DEFECTS AND ENVIRONMENTAL DEFECTS IN ACCORDANCE
WITH THE PROVISIONS OF SECTIONS 6.12 AND 6.14 (THE “AGGREGATE
INDEMNITY CAP”); AND ANY CLAIMS, ACTIONS OR DAMAGES OF ANY KIND WHATSOEVER
IN EXCESS OF THE AGGREGATE INDEMNITY CAP ARE HEREBY WAIVED AND RELEASED BY BREITBURN
AND ALL OTHER BREITBURN INDEMNIFIED PARTIES IN ALL RESPECTS (AND BREITBURN
SHALL INDEMNIFY, DEFEND AND HOLD QUICKSILVER AND THE OTHER QUICKSILVER
INDEMNIFIED

 

73

 

PARTIES
HARMLESS FROM AND AGAINST ANY SUCH CLAIMS, ACTIONS OR DAMAGES IN EXCESS OF SUCH
AGGREGATE INDEMNITY CAP), IN EACH CASE, REGARDLESS OF THE SOLE, JOINT,
CONCURRENT, COMPARATIVE, CONTRIBUTORY, ACTIVE, PASSIVE OR GROSS NEGLIGENCE,
WILLFUL MISCONDUCT, STRICT LIABILITY OR OTHER FAULT OR RESPONSIBILITY OF ANY
KIND OF QUICKSILVER, BREITBURN, THE TRANSFERRED COMPANIES, OR ANY OTHER PARTY
OR PERSON.

 

(c)                                  Survival; Exclusive Remedy. The indemnities provided in this
Section 9.2 and Article X shall survive Closing, as contemplated
in Section 9.1. Except as provided in Article X or in Section
11.13, the indemnity provided in this Section 9.2 shall be the sole
and exclusive remedy of BreitBurn and any other BreitBurn Indemnified Parties
from and after Closing against Quicksilver, at Law, in equity or otherwise,
relating to this Agreement (including, without limitation, any alleged breach
hereof) or the transactions contemplated hereby.

 

(d)                                 Claim Procedure. BreitBurn shall give Quicksilver prompt
written notice of any third party Action or other Damages claims which may give
rise to any indemnity obligation under this Section 9.2, together with
the estimated amount of such Action or Damages, and Quicksilver shall have the
right to assume the defense of any such Action through counsel of its own
choosing, by so notifying BreitBurn within sixty (60) days of receipt of
BreitBurn’s written notice; provided, however,
that Quicksilver’s counsel shall be reasonably satisfactory to BreitBurn. Failure
to give prompt notice shall not affect the indemnification obligations
hereunder in the absence of actual prejudice. If BreitBurn desires to
participate in, but not control, any such defense assumed by Quicksilver, it
may do so at its sole cost and expense. If Quicksilver declines to assume any
such defense, it shall be liable for all reasonable costs and expenses of
defending such Action incurred by BreitBurn, including reasonable fees and
disbursements of counsel in the event it is ultimately determined that
Quicksilver is liable for such Action pursuant to the terms of this Agreement. If
Quicksilver has assumed any such defense, but thereafter Quicksilver has failed
to diligently maintain such defense, then BreitBurn shall give Quicksilver
written notice thereof and, if Quicksilver does not take reasonable action to
remedy such failure within thirty (30) days after receipt, then BreitBurn may
assume such defense and Quicksilver shall continue to be liable for all
reasonable costs and expenses incurred in defending such actions, provided that BreitBurn thereafter diligently maintains such
defense and is commercially reasonable (given the size and nature of the claim
involved) in the manner of defense and the costs and expenses incurred. Quicksilver
shall not, without the written consent of a BreitBurn Indemnified Party, settle
any Action or claim against such BreitBurn Indemnified Party or consent to the
entry of any judgment with respect thereto that (i) does not result in a final
resolution of the BreitBurn Indemnified Party’s liability with respect to such
Action or claim (including, in the case of a settlement, an unconditional
written release of the BreitBurn Indemnified Party from all further liability
in respect of such Action or claim) or (ii) would result in the imposition of a
consent order, injunction or decree which would materially and adversely
restrict the future activity or conduct of the BreitBurn Indemnified Party,
other than conduct which violates a Law.

 

74

 

Section 9.3                                      Indemnification
by BreitBurn.

 

(a)                                  General Indemnity from BreitBurn; Assumed Liabilities. Upon,
from and after Closing, BreitBurn shall DEFEND, INDEMNIFY AND HOLD
HARMLESS Quicksilver, its respective successors and permitted
assigns and their respective shareholders, members, partners (general and
limited), officers, directors, managers, employees, agents and representatives
and each of their heirs, executors, successors and assigns (collectively, the “Quicksilver
Indemnified Parties”), from and against and in respect of any and all
Damages arising out of (i) any breach of any of the representations and
warranties made in Article V, or any corresponding representations and
warranties made in any certificate delivered by or on behalf of BreitBurn at
Closing pursuant to Section 2.11, (ii) any breach of any of the
covenants of BreitBurn in this Agreement, (iii) any Assumed Liabilities,
(iv) any Transferred Company Liabilities, (v) any of the Subject
Contracts or any other contract ancillary thereto and (vi) BreitBurn’s failure
to perform under any of the agreements to be entered into between BreitBurn and
Quicksilver pursuant to Section 6.23(d), IN EACH
CASE, REGARDLESS OF THE SOLE, JOINT, CONCURRENT, COMPARATIVE, CONTRIBUTORY,
ACTIVE, PASSIVE OR GROSS NEGLIGENCE OR WILLFUL MISCONDUCT (OTHER THAN THE GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT RELATING TO QUICKSILVER’S OBLIGATIONS TO
PROVIDE NOMINATION, SCHEDULING AND MARKETING SERVICES WITH RESPECT TO THE
SUBJECT CONTRACTS), STRICT LIABILITY OR OTHER FAULT OR RESPONSIBILITY OF ANY
KIND OF QUICKSILVER, BREITBURN, THE TRANSFERRED COMPANIES, OR ANY OTHER PARTY
OR PERSON.

 

(b)                                 Environmental Indemnity and Release. Notwithstanding
anything herein to the contrary, in addition to the indemnities set forth in Section
9.3(a), effective as of Closing, BreitBurn and its successors and assigns
hereby assume, agree to be responsible for and pay on a current basis, and
agree to DEFEND, INDEMNIFY, HOLD HARMLESS AND FOREVER
RELEASE the Quicksilver Indemnified Parties from and against any and
all Actions or Damages arising from, based upon, related to or associated with
any Environmental Liabilities or other environmental matter related or
attributable to the Acquired Assets, or assets or properties of any of the
Transferred Companies, regardless of whether such Actions or Damages arose
prior to, on or after the Effective Time, whether known or unknown, including,
without limitation, the presence, disposal or release of any Hazardous Material
or other material of any kind in, on or under the Acquired Assets, properties or
assets of any Transferred Companies or other property (whether neighboring or
otherwise) and including any liability of any Quicksilver Indemnified Party
with respect to the Acquired Assets, or assets or properties of any Transferred
Companies, under the Comprehensive Environmental Response, Compensation and
Liability Act of 1980, as amended (42 U.S.C. §§ 9601 et. seq.), the Resource
Conservation and Recovery Act of 1976 (42 U.S.C. § 6901 et. seq.), the Clean
Water Act (33 U.S.C. §§ 466 et. seq.), the Safe Drinking Water Act (14 U.S.C.
§§ 1401-1450), the Hazardous Materials Transportation Act (49 U.S.C. §§ 1801
et. seq.), the Toxic Substance Control Act (15 U.S.C. §§ 2601-2629), the Clean
Air Act (42 U.S.C. § 7401 et. seq.), as amended, and the Clean Air Act
Amendments of 1990, and all other federal, state and local Environmental Laws, IN EACH CASE, REGARDLESS OF THE SOLE, JOINT, CONCURRENT, COMPARATIVE,
CONTRIBUTORY, ACTIVE, PASSIVE OR GROSS NEGLIGENCE, WILLFUL MISCONDUCT, STRICT
LIABILITY OR OTHER FAULT OR RESPONSIBILITY OF ANY KIND OF QUICKSILVER, 

 

75

 

BREITBURN,
THE TRANSFERRED COMPANIES, OR ANY OTHER PARTY OR PERSON. EFFECTIVE AS OF
CLOSING, BREITBURN, FOR ITSELF AND ITS SUCCESSORS AND ASSIGNS, EXPRESSLY WAIVES
AND RELEASES ANY AND ALL RIGHTS AND REMEDIES WHICH IT MAY HAVE UNDER
ENVIRONMENTAL LAWS AGAINST QUICKSILVER OR ANY QUICKSILVER INDEMNIFIED PARTY
REGARDING ENVIRONMENTAL CONDITIONS OR ENVIRONMENTAL LIABILITIES, WHETHER FOR
CONTRIBUTION, INDEMNITY OR OTHERWISE, REGARDLESS OF THE FAULT OR NEGLIGENCE OF
QUICKSILVER OR ANY QUICKSILVER INDEMNIFIED PARTY, INCLUDING STRICT OR STATUTORY
LIABILITY OF QUICKSILVER OR ANY QUICKSILVER INDEMNIFIED PARTY UNDER ANY
APPLICABLE LAW.

 

(c)                                  Claim Procedures. Quicksilver shall give BreitBurn prompt
written notice of any third party Action or other Damages claims which may give
rise to any indemnity obligation under this Section 9.3, together with
the estimated amount of such Action or Damage, and BreitBurn shall have the
right to assume the defense of any such Action through counsel of its own
choosing, by so notifying Quicksilver within sixty (60) days of receipt of
Quicksilver’s written notice; provided, however,
that BreitBurn’s counsel shall be reasonably satisfactory to Quicksilver. Failure
to give prompt notice shall not affect the indemnification obligations
hereunder in the absence of actual prejudice. If Quicksilver desires to
participate in any such defense assumed by BreitBurn it may do so at its sole
cost and expense. If BreitBurn declines to assume any such defense, it shall be
liable for all reasonable costs and expenses of defending such Action incurred
by Quicksilver, including reasonable fees and disbursements of counsel in the
event it is ultimately determined that BreitBurn is liable for such Action
pursuant to the terms of this Agreement. If BreitBurn has assumed any such
defense, but thereafter BreitBurn has failed to diligently maintain such
defense, then Quicksilver shall give BreitBurn written notice thereof and, if
BreitBurn does not take reasonable action to remedy such failure within thirty
(30) days after receipt, then Quicksilver may assume such defense and BreitBurn
shall continue to be liable for all reasonable costs and expenses incurred in
defending such actions, provided that
Quicksilver diligently maintains such defense and is commercially reasonable
(given the size and nature of the claim involved) in the manner of defense and
the costs and expenses incurred. BreitBurn shall not, without the written
consent of a Quicksilver Indemnified Party, settle any Action or claim against
such Quicksilver Indemnified Party or consent to the entry of any judgment with
respect thereto that (i) does not result in a final resolution of the
Quicksilver Indemnified Party’s liability with respect to such Action or claim
(including, in the case of a settlement, an unconditional written release of
the Quicksilver Indemnified Party from all further liability in respect of such
Action or claim) or (ii) would result in the imposition of a consent order,
injunction or decree which would materially and adversely restrict the future
activity or conduct of the Quicksilver Indemnified Party, other than conduct
which violates a Law.

 

Section 9.4                                      Other
Indemnification Matters and Limitations.

 

(a)                                  The
amount of any Damages for which indemnification is provided under this Article
IX shall be computed net of any (i) insurance or other proceeds received by
the indemnified party in connection with such Damages (net of any collection costs,
and excluding the proceeds of any insurance policy issued or underwritten by
the indemnified party or its

 

76

 

Affiliates),
(ii) any Tax credits or other Tax benefits received by the indemnified party in
connection with such Damages.

 

(b)                                 Each
indemnified party agrees that it shall pursue in good faith claims under any
applicable insurance policies (excluding any insurance policy issued or
underwritten by the indemnified person or its Affiliates) and against other
third parties (other than its Affiliates) who may be responsible for Damages.

 

(c)                                  Notwithstanding
anything to the contrary contained in this Agreement, the Parties agree that
the indemnification provisions set forth in this Agreement shall not apply to
any Damages to the extent such Damages are accounted for in the calculations of
the adjustments set forth in Article II.

 

Section 9.5                                      Materiality Exclusion. Notwithstanding anything to the contrary
contained in this Agreement, for the purposes of determining if after the
Closing there has been a breach of any representation or warranty hereunder and
the amount of the Damages in respect thereof, the representations and
warranties shall, for purposes of this Article IX, be read without
giving effect to any materiality, Material Adverse Effect or qualification with
a similar meaning contained or incorporated directly or indirectly in such
representation or warranty.

ARTICLE X

TAX MATTERS

 

Section 10.1                                Preparation
and Filing of Tax Returns.

 

(a)                                  To
the extent permitted by Law or administrative practice the taxable year of each
Acquired Company (which, for purposes of this Article X, includes Terra
Pipeline Company) that includes the Closing Date shall be treated as closing on
(and including) the Closing Date.

 

(b)                                 For
purposes of determining the Taxes attributable to a Pre-Closing Tax
Period:  (i) in the case of Taxes
that are either (x) based upon or related to income or receipts or
(y) imposed in connection with any sale or other transfer or assignment of
property (real or personal, tangible or intangible), shall be deemed equal to
the amount which would be payable if the taxable period ended on and included
the Closing Date and (ii) in the case of Taxes imposed on a periodic basis
or otherwise measured by the level of any item, deemed to be the amount of such
Taxes for the entire period (or, in the case of such Taxes determined on an
arrears basis, the amount of such Taxes for the immediately preceding period),
multiplied by a fraction the numerator of which is the number of days in the
Pre-Closing Tax Period and the denominator of which is the number of days in
the entire taxable period.

 

(c)                                  Except
as provided in Section 10.3 and Section 10.7, as between
BreitBurn and its Affiliates and Quicksilver and its Affiliates, Quicksilver
and its Affiliates shall be responsible and indemnify BreitBurn for the payment
of (i) 100% of any and all Taxes due from or with respect to the Acquired
Companies for any Pre-Closing Tax Period, including any Tax liability that
arises as a result of the Conversions, under Treasury Regulation section
1.1502-6 or any analogous state, local or foreign law or regulation, or
pursuant to a Tax sharing or indemnification agreement or arrangement, (ii) any
Taxes attributable to the transfer of the

 

77

 

Interests by
Quicksilver to BreitBurn pursuant to this Agreement, (iii) any liability for
Taxes imposed on BreitBurn, its Affiliates (including the Acquired Companies),
or the direct or indirect owners of their respective equity interests as a
result of a breach of the representations set forth in Section 4.11,
(iv) 5.5385% of any and all Taxes due from WCGP for any Pre-Closing Tax Period,
and (v) any liabilities, costs, expenses (including, without limitation,
reasonable expenses of investigation and attorneys’ and accountants’ fees and
expenses) arising out of or incident to the imposition, assessment or assertion
of any liabilities described in (i), (ii), (iii) or (iv), including those incurred
in the contest in good faith in appropriate proceedings relating to the
imposition, assessment or assertion of such liabilities, in each case incurred
or suffered by BreitBurn, any of its Affiliates (including the Acquired
Companies) after the Closing Date.

 

(d)                                 Quicksilver
shall ensure that (i) all items of income, gain, loss, deduction and
credit (“Tax Items”) of the Acquired Companies that are required to be
included in the consolidated federal income Tax Returns (and the state income
Tax Returns of any state that permits consolidated, combined or unitary income
Tax Returns, if any) of the Quicksilver Group are so included therein,
(ii) any such Tax Returns that include Tax Items of the Acquired Companies
are timely filed with the appropriate Taxing Authorities, and (iv) all
such Taxes owed with respect to such Tax Items (whether or not shown on any
such Tax Return) are timely paid.

 

(e)                                  For
all Tax Returns of each of the Acquired Companies covering periods ending on or
prior to the Closing Date that are filed after the Closing Date and are not
described in paragraph (d) above, BreitBurn shall cause such Tax Returns to be
prepared in a manner consistent with practices followed in prior years, except
as otherwise required by Law. BreitBurn shall cause to be included in each such
Tax Return all Tax Items required to be included therein, and shall furnish a
copy of each such Tax Return to Quicksilver at least fifteen (15) days prior to
the due date (including extensions) for filing such Tax Return, along with a
statement setting forth (i) for the Acquired Companies, the amount of the Taxes
shown to be due on such Tax Return and (ii) for WCGP, 5.5385% of the
amount of the Taxes shown to be due on such Tax Return. BreitBurn shall permit
Quicksilver to review and comment on such Tax Returns and shall make such
revisions to such Tax Returns as reasonably requested by Quicksilver not later
than three (3) days prior to the due date (including extensions) of such Tax
Return. Quicksilver shall deliver to BreitBurn the amount shown on such
statement no later than three days prior to the due date (including extensions)
for filing such Tax Return but only to the extent that such amount has not been
given effect in the calculations of the Initial Consideration adjustment set
forth in Section 2.1(b). BreitBurn shall timely file or cause the
Acquired Companies to timely file such Tax Returns and pay all Taxes due with
respect to such Tax Returns. Quicksilver shall be entitled to any refund of
Taxes due with respect to any Pre-Closing Period, and BreitBurn shall pay over
to Quicksilver any such refund, within fifteen (15) days after receipt thereof
net of any Taxes or costs resulting from the receipt of such refund. Tax items
of each of the Acquired Companies shall be apportioned for all income Tax
purposes by closing the books of each of the Acquired Companies at the end of
the Closing Date.

 

(f)                                    With
respect to any Tax Return covering a taxable period beginning on or before the
Closing Date and ending after the Closing Date that is required to be filed
after the Closing Date with respect to a Acquired Company, BreitBurn shall
cause such Tax Return to be prepared in a manner consistent with practices
followed in prior years, except as otherwise

 

78

 

required by
Law, shall cause to be included in such Tax Return all Tax Items required to be
included therein, and at least fifteen (15) days prior to the due date
(including extensions) of such Tax Return shall furnish a copy of such Tax
Return to Quicksilver along with a statement setting forth the amount of Taxes
attributable to the Pre-Closing Tax Period. BreitBurn shall permit Quicksilver
to review and comment on such Tax Returns and make such revisions to such Tax
Returns as reasonably requested by Quicksilver not later than three (3) days
prior to the due date (including extensions) of such Tax Return. No later than
three days prior to the due date (including extensions) of (i) any such
Tax Return for the Acquired Companies, Quicksilver shall deliver to BreitBurn
the amount, if any, of the unpaid Taxes attributable to the Pre-Closing Tax
Period and (ii) any such Tax Return for WCGP, Quicksilver shall deliver to
BreitBurn 5.5385% of the amount, if any, of the unpaid Taxes attributable to
the Pre-Closing Period, in each case, only to the extent that such amount has
not been given effect in the calculations of the adjustment set forth in Section 2.1(b).
BreitBurn shall timely file or cause the Acquired Companies to timely file such
Tax Returns and pay all Taxes due with respect to such Tax Return. Any Tax
refunds that are received by BreitBurn or the Acquired Companies that relate to
Tax periods or portions thereof ending on or before the Closing Date shall be
for the account of Quicksilver, and BreitBurn shall pay over to Quicksilver any
such refund, or appropriate portion thereof, net of any Taxes or costs
resulting from the receipt of such refund, within 15 days after receipt
thereof.

 

(g)                                 Except
as may be required by Law, no amended Tax Return shall be filed, and no change
in any Tax accounting method or Tax election shall be made by, on behalf of, or
with respect to a Acquired Company, for any Pre-Closing Tax Period without the
consent of Quicksilver, which may be withheld in Quicksilver’s reasonable
discretion.

 

(h)                                 BreitBurn
and Quicksilver agree to provide such assistance as may reasonably be requested
by the other Party in connection with the preparation of any Tax Return, any
Action or other examination by any Taxing Authority or any Action relating to
liability for Taxes, and each will retain and provide the requesting Party with
any records or information which may be relevant to such return, audit or
examination, proceedings or determination. Any information obtained pursuant to
this Section 10.1 or pursuant to any other Section hereof providing
for the sharing of information relating to or review of any Tax Return or other
schedule relating to Taxes shall be kept confidential.

 

(i)                                     BreitBurn
and Quicksilver will preserve and retain all schedules, work papers and other
documents relating to any Tax Returns of the Acquired Companies or to any
claims, audits or other proceeding affecting the Acquired Companies until the
expiration of the statute of limitations (including extensions) applicable to
the taxable period to which such documents relate or until the final
determination of any controversy with respect to such taxable period, and until
the final determination of any payments that may be required with respect to
such taxable period under this Agreement.

 

79

 

Section 10.2                                Tax
Treatment of Payments. Except as required by Law, the Parties shall treat
any indemnification payment or adjustment to the Initial Consideration made
pursuant to this Agreement as an adjustment to the Final Consideration for Tax
purposes.

 

Section 10.3                                Transfer
Taxes. All Transfer Taxes incurred in connection with this Agreement, the
contribution of the Interests and the transactions contemplated hereby shall be
borne solely by BreitBurn. The Party with primary responsibility under
applicable Law shall file, to the extent required by applicable Law, all
necessary Tax Returns and other documentation with respect to such Transfer
Taxes. For purposes of this Agreement, “Transfer Taxes” shall mean
transfer, documentary, sales, use, goods and services, registration, stamp
duty, gross receipts, excise, transfer and conveyance and other similar Taxes,
duties, fees or charges (including all applicable real estate transfer taxes),
together with any interest thereon, penalties, fines, costs, fees, additions to
Tax or additional amounts with respect thereto.

 

Section 10.4                                Allocation
of Consideration. The Initial Consideration, as adjusted by the other
provisions of Article II or Section 6.12 or 6.13 and any
indemnification payments, plus the amount of the Acquired Company Liabilities
(the “Total Consideration”), shall be allocated among the QRI Assets and
the assets and properties of the Acquired Companies (collectively with the QRI
Assets, the “Contributed Assets”) in accordance with Section 1060 of the
Code and the Treasury regulations thereunder (and any similar provision of
state, local or foreign Law, as appropriate) (the “Consideration Allocation”).
BreitBurn and Quicksilver agree that the unadjusted Total Consideration shall
be allocated among the Contributed Assets in accordance with the principles of
Section 1060 of the Code and the Treasury Regulations, as set forth in Exhibit D
of this Agreement (individually, a “Tax Allocated Value”, and
collectively, the “Tax Allocated Values”). Prior to Closing, the Parties
shall prepare a mutually agreed schedule setting forth any necessary
adjustments to the Tax Allocated Values, based upon the Closing Date
Consideration (the “Closing Consideration Allocation Schedule”). Any
post-Closing adjustments with respect to the consideration for the Contributed
Assets shall be treated as adjustments to the Consideration Allocation, which
shall be made in accordance with Section 1060 of the Code and the Treasury
Regulations thereunder (and any similar provision of state, local or foreign
Law, as appropriate). Quicksilver and BreitBurn shall report the transactions
contemplated by this Agreement in a manner consistent with the Consideration
Allocation, such as reporting of asset values and other items for purposes of
all federal, state, and local Tax Returns, including without limitation,
Internal Revenue Service Form 8594. Quicksilver and BreitBurn shall not
take any position in any Tax Return, Tax proceeding or Tax audit that is
inconsistent with the Consideration Allocation, except as required by Law; provided, however, that neither BreitBurn nor Quicksilver
shall be unreasonably impeded in its ability to settle any Tax audit or other
Action related to Taxes.

 

Section 10.5                                Tax
Treatment of Transaction. Before the Closing Date, each of Terra, GTG,
Mercury and Terra Pipeline Company will merge into a newly-formed,
single-member limited liability company (collectively, the “Conversions”),
with the result that each of the Acquired Companies will be disregarded as an
entity separate from Quicksilver for United States federal Tax purposes (and
state, local, and foreign Tax purposes where applicable). Accordingly, as a
result of each of the Acquired Companies being disregarded as an entity
separate from Quicksilver and BreitBurn being disregarded as an entity separate
from BreitBurn Parent for United States federal Tax purposes (and state, local,
and foreign Tax purposes where

 

80

 

applicable), the Parties intend
for the transfer of the QRI Assets and the equity interests in the Acquired
Companies by Quicksilver to BreitBurn pursuant to this Agreement to be treated
for United States federal income Tax purposes (and state, local, and foreign
Tax purposes where applicable) as the contribution by Quicksilver to BreitBurn
Parent of the Contributed Assets, subject to the Acquired Company Liabilities,
in exchange for the Cash Consideration and the Equity Consideration (the “Tax
Construct”). The Parties acknowledge and agree that the Tax Construct will
be treated in part as a sale for purposes of Section 707 of the Code, and for
purposes of determining the portion of the Total Consideration treated as sale
consideration and the portion of the Contributed Assets treated as being sold
for purposes of Section 707 of the Code, the Parties agree to treat and report
for United States federal income Tax purposes (and state, local, and foreign
Tax purposes where applicable) a portion of the Cash Consideration as a
reimbursement of “capital expenditures,” within the meaning of Treasury
Regulations section 1.707-4(d), to the extent Quicksilver provides
documentation adequate to support such treatment.

 

Section 10.6                                BreitBurn’s Tax Indemnity. Notwithstanding any provision of this
Agreement to the contrary, including any provision in Section 10.1(c)
and Article IX, as between Quicksilver and its Affiliates and BreitBurn
and its Affiliates, BreitBurn and its Affiliates shall be responsible and
indemnify Quicksilver for (i) any liability for Taxes imposed on and losses
suffered by Quicksilver and its Affiliates as a result of a breach of the
representations set forth in Section 5.12, and (ii) any liabilities,
costs, expenses (including, without limitation, reasonable expenses of
investigation and attorneys’ and accountants’ fees and expenses) arising out of
or incident to the imposition, assessment or assertion of any Tax or loss
described in clause (i), including those incurred in the contest in good faith
in appropriate proceedings relating to the imposition, assessment or assertion
of such Tax, in each case incurred or suffered by Quicksilver or any of its
Affiliates after the Closing Date.

 

Section 10.7                                Tax Sharing Agreements. All Tax sharing or similar Contracts with
respect to or involving any of the Acquired Companies shall be terminated as of
the Closing Date and, after the Closing Date, none of such companies shall be
bound thereby or have any liability thereunder (whether relating to any
pre-Closing or post-Closing period).

 

Section 10.8                                Conflict.
In the event of a conflict between the provisions of this Article X and
any other provisions of this Agreement, this Article X shall control.

 

Section 10.9                                Procedures
Relating to Indemnification of Tax Claims.  

 

(a)                                  If
a claim shall be made by any Taxing Authority, for which Quicksilver is or may
be liable pursuant to this Agreement, BreitBurn shall notify Quicksilver in
writing within ten (10) Business Days of receipt by BreitBurn of notice of such
claim (a “Tax Claim”). Failure to give prompt notice shall not affect
the indemnification obligations hereunder in the absence of actual material
prejudice.

 

(b)                                 With
respect to any Tax Claim, Quicksilver, at Quicksilver’s expense, shall control
all proceedings taken in connection with such Tax Claim (including selection of
counsel), and BreitBurn shall execute or cause to be executed powers of
attorney or other documents necessary to enable Quicksilver to take all actions
that do not materially adversely affect BreitBurn or its Affiliates, or the
Acquired Companies, or the direct or indirect owners of

 

81

 

their
respective equity interests. Quicksilver shall permit BreitBurn to participate
in (but not control) such proceedings through counsel chosen by BreitBurn (but
the fees and expenses of such counsel shall be paid by BreitBurn). Quicksilver
may in its sole discretion pursue or forego any and all administrative appeals,
proceedings, hearings and conferences with any Taxing Authority with respect to
such Tax Claim, and may initiate any claim for refund, file any amended return,
or take any other action which is deemed appropriate by Quicksilver with
respect to such Tax Claim, provided such
actions do not materially adversely affect BreitBurn or its Affiliates, the
Acquired Companies, or the direct or indirect owners of their respective equity
interests. Notwithstanding the foregoing, Quicksilver and BreitBurn shall
jointly control all proceedings in connection with any Tax Claim relating
solely to Taxes for a taxable period beginning before the Closing Date and
ending after the Closing Date, and shall jointly bear and pay costs and
expenses related to such proceedings. No party shall settle a Tax Claim
relating solely to Taxes of the Acquired Companies or WCGP for a Pre-Closing
Tax Period or a taxable period beginning before the Closing Date and ending
after the Closing Date without the other party’s prior written consent (which
consent may not be unreasonably withheld, conditioned or delayed).

 

Section 10.10                          Like
Kind Exchange. Any Party may elect to structure the assignment and
conveyance of the portion of the QRI Assets for which the Cash Consideration is
treated as having been paid as part of a like-kind exchange under Section 1031
of the Code. The parties agree to cooperate with one another with respect to
the like-kind exchange and to execute all documents, conveyances and other
instruments necessary to effectuate an exchange. The Party requesting a
like-kind exchange shall bear all costs and expenses and liability associated
therewith.

 

Section 10.11                          Consents. If either Saginaw or
TWPP does not currently have in effect a Section 754 Election, Quicksilver
shall use commercially reasonable efforts to obtain any required consents from
the partners of Saginaw and TWPP, as applicable, to authorize Saginaw and TWPP
to make a Section 754 Election that will be effective on the Closing Date (the “Section
754 Consents”); provided that Quicksilver shall not be obligated to pay any
consideration or waive or release any right or privilege as part of such
efforts.

 

Section 10.12                          Survival.
Notwithstanding anything to the contrary in this Agreement, all
representations, warranties, covenants, agreements and indemnities relating to
Taxes contained in this Agreement (and any certificates or documents relating
thereto delivered in connection with this Agreement) shall survive the Closing
and shall not terminate until the date that is sixty (60) days after the expiration
of the applicable statute of limitations, including extensions thereof, with
respect to such Tax matter.

This Agreement shall inure to the benefit of and be binding on the Parties and
their respective successors and permitted assigns. This Agreement shall not be
assigned by any Party without the express prior written consent of the other
Party, in its sole discretion, and any attempted assignment, without such
consent, shall be null and void. In no event shall any assignment or transfer
hereunder serve to release or discharge the assigning Party from any of its
duties and obligations hereunder, unless expressly released, in writing, by the
non-assigning Party. Notwithstanding the foregoing, BreitBurn may designate one
or more of its Affiliates as the party to whom title to all or any part of the
Interests will be conveyed, assigned and transferred at the Closing; provided, however, such designation and the transfer of
title to such designee shall not serve to release or discharge BreitBurn from
any of its duties and obligations hereunder.

 

Section 11.4                                Amendment;
Waiver. Except as otherwise provided in Section 6.9, this Agreement
may be amended, supplemented or otherwise modified only by a written instrument
executed by each of the Parties hereto. No waiver by any Party of any of the
provisions hereof shall be effective unless explicitly set forth in writing and
executed by the Party so waiving. Except as provided in the preceding sentence,
no action taken pursuant to this Agreement, including any investigation by or
on behalf of any Party, shall be deemed to constitute a waiver by the Party
taking such action of compliance with any representations, warranties,
covenants or agreements contained herein, and in any documents delivered or to
be delivered pursuant to this Agreement and in connection with Closing hereunder.
The waiver by any Party of a breach of any provision of this Agreement shall
not operate or be construed as a waiver of any subsequent breach.

 

Section 11.5                                No
Third Party Beneficiaries. Except to the extent a third party is expressly
given rights herein, including in Article IX, this Agreement is not
intended, nor shall it be deemed, construed or interpreted, to confer upon any
Person not a Party (or a successor and assign permitted herein) any rights or
remedies hereunder. Each BreitBurn Indemnified Party and each Quicksilver
Indemnified Party is a third party beneficiary to the extent of the indemnity,
defense and hold harmless obligations owed to such Person under Article IX;
provided, however, that any claim to be
indemnified, defended or held harmless hereunder on behalf of a BreitBurn
Indemnified Party or a Quicksilver Indemnified Party must be made and
administered by a Party to this Agreement or its successors or permitted
assigns. Quicksilver shall not have any direct liability or obligation to any
Quicksilver Indemnified Party under this Agreement or be liable to any
Quicksilver Indemnified Party for any election or non-election or any act or
failure to act under or in regard to any term of this Agreement, and BreitBurn

jurisdiction), other than matters dealing with the ownership of real property
or interests therein, which shall be governed by the laws of the state where
such property is located.
