        Effect. Schedule

        Entities. Notwithstanding the foregoing, the Selling Parties may disclose
        any
        information relating to the business and operations of the GP Entities,
        including financial information, (i) if required by law or applicable stock
        exchange rule, (ii) if such disclosures are made in public filings with a
        stock
        exchange and are in the ordinary course of business consistent with past
        practices and (iii) to such other Persons if, at the time such information
        is
        provided, such Person is already in the possession of such information.

       

      (b) Except
        as
        consented to by Buyer in writing, none of the Selling Parties and their
        Affiliates shall release any Person from any Bidder Confidentiality Agreement
        now existing with respect to the Sellers’ LLC Interests or GP Entities or waive
        or amend any provision thereof. After the Closing Date, the Selling Parties
        shall use commercially reasonable efforts to have all confidential information
        either returned to the Selling Parties or, to the extent permitted by applicable
        law, destroyed. Furthermore, if any parties to the Bidder Confidentiality
        Agreements breach the terms of their respective agreement, upon the request
        of
        Buyer, the Selling Parties and the Seller Parent shall cooperate with Buyer
        to
        enforce the terms of such Bidder Confidentiality Agreements at Buyer’s cost and
        expense. The term “Bidder
        Confidentiality Agreements”
shall
        mean the confidentiality agreements between any of the Seller Parent, the
        Selling Parties or any of their Affiliates or advisors and prospective
        purchasers (other than Buyer or its Affiliates) with respect to Sellers’ LLC
        Interests.

       

      Section
        5.4 Tax
        Covenants.

       

      (a) Buyer
        shall use its commercially reasonable efforts to cause the GP Entities to
        prepare and file with the appropriate federal, state, local and foreign
        governmental agencies all Tax Returns due after the Closing Date and to cause
        the GP Entities to pay the Taxes of the GP Entities shown to be due on such
        Tax
        Returns. 

       

      (b) In
        the
        case of a GP Entity’s Tax Return that is governed by Section 706 of the Code or
        an analogous provision of foreign, state or local law, that is due after
        the
        Closing Date and that includes a period on or before the Closing Date, Buyer
        shall use its commercially reasonable efforts to cause the GP Entities to
        prepare such Tax Returns in accordance with Section 706(d), based upon a
        closing
        of the books of such GP Entity on the Closing Date and, not later than 30
        days
        prior to the due date or the extended filing date, if applicable, of each
        such
        Tax Return, Buyer shall deliver a copy of such Tax Return to the Selling
        Parties
        and Buyer shall make or use its commercially reasonable efforts to cause
        to be
        made such changes in such Tax Return as the Selling Parties reasonably
        request.

       

      (c) All
        excise, sales, use, transfer (including real property transfer or gains),
        stamp,
        documentary, filing, recordation and other similar Taxes resulting from the
        transactions contemplated by this Agreement (the “Transfer
        Taxes”)
        shall
        be borne and paid by Buyer. Notwithstanding anything to the contrary in this
        Section
        5.4,
        any Tax
        Return that must be filed in connection with Transfer Taxes shall be prepared
        and filed when due by the party responsible under applicable law for filing
        such
        Tax Return, and such party will provide such Tax Returns to the other party
        at
        least ten days prior to the due date for such Tax Returns and shall provide
        such
        other party with a reasonable opportunity to comment on such Tax Returns
        during
        such ten-day period. If the Person responsible for filing the Tax Return
        is a
        Selling Party, such Person may, but is not required to, pay any Taxes due
        with
        such Tax Return and, in such case, Buyer promptly shall reimburse such Taxes
        to
        such Selling Party.

      (d) Buyer
        shall provide to each Seller Party by January 31, 2009, the information
        necessary to allow each Selling Party to file the statement required by the
        second sentence of Treasury Regulation §1.751-1(b)(5), which information will be
        based upon the unaudited financial statements of Buyer.

       

      Section
        5.5 Director
        Resignations.
        On the
        Closing Date, the Selling Parties shall cause to be delivered to Buyer duly
        executed resignations of the directors of BreitBurn Management and BreitBurn
        GP
        listed on Exhibit
        5.5.

       

      Section
        5.6 Directors’
        and Officers’ Indemnification and Insurance.

       

      (a) Buyer
        shall ensure that the Organizational Documents of the GP Entities contain
        provisions no less favorable to the Persons covered thereby with respect
        to
        exculpation, indemnification and advancement of expenses than are set forth
        in
        the Organizational Documents of the GP Entities as of the date of this
        Agreement, which provisions shall not be amended, repealed or otherwise modified
        for a period of six years from the Closing Date in any manner that would
        affect
        adversely the rights thereunder of individuals who at any time on or prior
        to
        the Closing Date were directors, officers, employees, fiduciaries or agents
        of
        any GP Entity in respect of actions or omissions occurring at or prior to
        the
        Closing (including, without limitation, the matters contemplated by this
        Agreement), unless such modification is required by law.

       

      (b) From
        and
        after the Closing, Buyer shall cause the GP Entities, to the fullest extent
        permitted under applicable law, to indemnify, hold harmless and advance expenses
        to each present and former director, officer, employee, fiduciary and agent
        of
        the GP Entities (collectively, the “Indemnified
        Officers and Directors”)
        against all costs and expenses (including attorneys’ fees), judgments, fines,
        losses, claims, damages, inquiries, liabilities and settlement amounts paid
        in
        connection with any threatened or actual claim, action, suit, proceeding
        or
        investigation (whether arising before or after the Closing), whether civil,
        criminal, administrative or investigative, arising out of or pertaining to
        any
        action or omission in their capacity as an officer, director, employee,
        fiduciary or agent of a GP Entity (including, without limitation, any claim
        arising out of this Agreement or the transactions contemplated hereby), whether
        occurring before or after the Closing, whether asserted or claimed prior
        to, at
        or after the Closing, for a period of six years after the Closing Date, in
        each
        case to the fullest extent permitted under applicable law (and shall pay
        any
        expenses in advance of the final disposition of any such action or proceeding
        to
        each Indemnified Officer and Director to the fullest extent permitted under
        applicable law, upon receipt from the Indemnified Officer or Director to
        whom
        expenses are advanced of any undertaking to repay such advances required
        under
        applicable law). In the event of any such claim, action, suit, proceeding
        or
        investigation, (i) the Indemnified Officers and Directors may retain counsel
        (including local counsel) reasonably acceptable to the GP Entities, and Buyer
        shall cause the GP Entities to pay the reasonable fees and expenses of which
        promptly after statements therefor are received and (ii) Buyer shall cause
        the
        GP Entities to cooperate in the defense of any such matter; provided, however,
        that the GP Entities shall not be liable for any settlement effected without
        their written consent (which consent shall not be unreasonably withheld,
        delayed
        or conditioned); and provided, further, that the GP Entities shall not be
        obligated pursuant to this subsection (b) to pay the fees and expenses of
        more
        than one counsel (plus appropriate local counsel) for all Indemnified Officers
        and Directors in any single action unless there is, as determined by counsel
        to
        the Indemnified Officers and Directors, under applicable standards of
        professional conduct, a conflict or a reasonable likelihood of a conflict
        on any
        significant issue between the positions of any two or more Indemnified Officers
        and Directors, in which case such additional counsel (including local counsel)
        as may be required to avoid any such conflict or likely conflict may be retained
        by the Indemnified Officers and Directors at the expense of the GP Entities;
        and
        provided, further, that, in the event that any claim for indemnification
        is
        asserted or made prior to the Closing or within such six-year period, all
        rights
        to indemnification in respect of such claim shall continue until the final
        disposition of such claim. Buyer shall cause the GP Entities to pay all
        reasonable expenses, including attorneys’ fees, that may be incurred by any
        Indemnified Officer or Director in enforcing the indemnity and other obligations
        provided in this Section
        5.6.

      (c) From
        and
        for a period of six years after the Closing, Buyer shall cause the GP Entities
        to maintain in effect the current directors’ and officers’ liability insurance
        policies maintained by them (provided, that the GP Entities may substitute
        therefor policies of at least the same coverage and amounts containing terms
        and
        conditions that are no less advantageous to such officers and directors so
        long
        as substitution does not result in gaps or lapses in coverage) with respect
        to
        matters occurring prior to the Closing.

       

      (d) In
        the
        event Buyer or a GP Entity or any of their respective successors or assigns
        (i)
        consolidates with or merges into any other Person and shall not be the
        continuing or surviving company or entity of such consolidation or merger
        or
        converts into any other person or (ii) transfers all or substantially all
        of its
        properties and assets to any Person, then, and in each such case, Buyer shall
        cause proper provision to be made so that the successors and assigns of Buyer
        or
        such GP Entity shall assume the obligations set forth in this Section
        5.6.

       

      (e) The
        obligations of Buyer and the GP Entities under this Section
        5.6
        shall
        not be terminated or modified in such a manner as to adversely affect any
        director, officer, employee, fiduciary and agent to whom this Section
        5.6
        applies
        without the consent of each affected director, officer, employee, fiduciary
        and
        agent (it being expressly agreed that the directors, officers, employees,
        fiduciaries and agents to whom this Section
        5.6
        applies
        shall be third-party beneficiaries of this Section
        5.6).
        The
        rights of each Indemnified Officers and Directors hereunder shall be in addition
        to any other rights such Indemnified Officer or Director may have under the
        Organizational Documents of the GP Entities, under the laws of the State
        of
        Delaware or otherwise.

       

      Section
        5.7 Equity
        and Equity-Related Compensation Plans.
        The
        parties acknowledge and agree that, with respect to the Equity Plans described
        on Schedule
        3.13(b),
        the
        liabilities with respect to all compensation owed pursuant to such Equity
        Plans
        for all awards made prior to the Closing Date (collectively, the “Pre-Existing
        Equity Plans Obligations”),
        are
        currently, and notwithstanding the occurrence of the Closing will continue
        to
        be, allocated as reflected on Schedule
        3.13(b)
        under
        the column entitled “Liable Party.” For the sake of clarity, notwithstanding the
        occurrence of the Closing and the transactions contemplated by this Agreement,
        (a) BECLP shall retain the liability for all Pre-Existing Equity Plans
        Obligations that are reflected on Schedule
        3.13(b)
        as those
        of BECLP, (b) the Partnership shall retain the liability for all Pre-Existing
        Equity Plans Obligations that are reflected on Schedule
        3.13(b)
        as those
        of the Partnership and (c) the liability for compensation owed pursuant to
        any
        Equity Plan as to which there is shared liability as reflected on Schedule
        3.13(b)
        shall be
        retained by BECLP and the Partnership respectively in accordance with their
        respective allocation percentages reflected on Schedule
        3.13(b).
        From
        and after the Closing, Buyer will cause the Partnership and Pro GP will cause
        BECLP to honor and perform their respective obligations under the Equity
        Plans,
        as reflected on Schedule
        3.13(b)
        and as
        agreed pursuant to this Section 5.7. In the event that Pro GP at any time
        ceases
        to be the general partner of BECLP, Pro GP shall assign its obligations under
        this Section 5.7 to the new general partner of BECLP (or successor controlling
        person or entity) and such new general partner (or successor controlling
        person
        or entity) shall explicitly agree in writing to assume and perform such
        obligations. In the event that BreitBurn GP at any time ceases to be the
        general
        partner of the Partnership, BreitBurn GP shall assign its obligations under
        this
Section
        5.7
        to the
        new general partner of the Partnership (or successor controlling person or
        entity) and such new general partner (or successor controlling person or
        entity)
        shall explicitly agree in writing to assume and perform such obligations.
        The
        provisions of this Section
        5.7
        supersede any conflicting provisions in that certain Adoption Agreement by
        and
        between BECLP and BreitBurn Management. Except as provided in this Section
        5.7,
        each of
        the parties hereto acknowledges and agrees that this Agreement shall not
        relieve
        either party from any obligations or liabilities to the other party under
        any
        existing agreement for services rendered prior to the date of this
        Agreement.

      Section
        5.8 Employment
        Agreements.
        Pro GP
        hereby assigns to Buyer and Buyer hereby assumes and agrees to perform the
        obligations of the “Employer” under the Employment Agreements to the same extent
        that the “Employer” (as such term is defined in each such agreement) would be
        required to perform such obligations if no assignment by Pro GP had occurred
        in
        connection with the transactions contemplated by this Agreement. The term
        “Employment Agreements” means (a) Second Amended and Restated Employment
        Agreement, dated as of December 31, 2007, by and among BreitBurn Management,
        Pro
        GP, BreitBurn GP and Randall Breitenbach, (b) Employment Agreement, dated
        as of
        December 26, 2007, by and among BreitBurn Management, Pro GP, BreitBurn GP
        and
        Mark Pease, (c) Employment Agreement, dated as of July 7, 2006, between James
        G.
        Jackson and BreitBurn Energy, as amended by that certain Amendment to Employment
        Agreement, dated as of October 10, 2006, among James G. Jackson, BreitBurn
        Energy, BreitBurn GP, Pro GP and BreitBurn Management and (d) Employment
        Agreement, dated as of January 29, 2008, by and among Gregory C. Brown,
        BreitBurn Management, Pro GP and BreitBurn GP and (e) Second Amended and
        Restated Employment Agreement, dated as of December 31, 2007, by and among
        Halbert Washburn, BreitBurn Management, BreitBurn GP and Pro GP. For the
        avoidance of doubt, (1) such assignment and assumption shall not apply with
        respect to obligations arising under or related to the Equity Plans and any
        employee incentive rights for which the Devco Group (as defined in the ASA)
        has
        agreed to bear costs in accordance with Section 4.1(c) of the the Amended
        and
        Restated Administrative Services Agreement between BreitBurn Management and
        BreitBurn Energy dated the date hereof (the “ASA”), for which Pro GP will remain
        obligated in accordance with the provisions of this Agreement, the ASA, and
        the
        applicable employment agreements, award agreements and plans, and (2) such
        obligations shall not duplicate the obligations of Pro GP under Section 4.1
        of
        the ASA.

        From

        to timely pay, as and when due, any and all amounts owed by the Partnership
        or
        such Affiliates to the Selling Parties or their Affiliates as of the Closing
        Date. From and after the Closing Date, Selling Parties and their Affiliates
        shall timely pay, as and when due, any and all amounts owed by the Selling
        Parties or its Affiliates to the Partnership or its Affiliates as of the

      (i) the
        Selling Parties aggregate liability under Section
        9.2(a)(i)
        in
        respect of a breach or inaccuracy of the representations in Sections

Section

        3.7
        and
Section
        3.13(c),

        indemnification for any Losses asserted against the Selling Parties under
        Section
        9.2(a)(i)
        shall be
        required unless and until the cumulative aggregate amount of such Losses
        exceeds
        one percent (1%) of the Purchase Price (the “Deductible”),
        at
        which point the Selling Parties shall be obligated to indemnify the Buyer
        Indemnified Parties only as to the amount of such Losses in excess of the
        Deductible;

      (iii) the
        amount of any Losses suffered by a Seller Indemnified Party or a Buyer
        Indemnified Party, as the case may be (such party seeking indemnification
        pursuant to this Article
        IX,
        the
“Indemnified
        Party,”
and
        the other party, the “Indemnifying
        Party”),
        shall
        be reduced by any third-party insurance, third-party recoveries and available
        Tax benefits received or realizable by the Indemnified Party through its
        commercially reasonable efforts in respect of or as a result of such Losses.
        The
        Indemnified Party shall use commercially reasonable efforts to collect any
        amounts available under such insurance coverage and from such other third-party
        alleged to have responsibility and to realize any available Tax
        benefits;

       

      (iv) no
        claim
        may be asserted nor may any action be commenced against any party for breach
        or
        inaccuracy of any representation or breach of a warranty, unless written
        notice
        of such claim or action is received by the other party describing in reasonable
        detail the facts and circumstances with respect to the subject matter of
        such
        claim or action on or prior to the date on which the representation or warranty
        on which such claim or action is based ceases to survive as set forth in
        Section
        9.1;
        and

       

      (v) no
        Indemnified Party shall be entitled under this Agreement to multiple recovery
        for the same Losses.

       

      Section
        9.3 Procedures.
        Any
        Indemnified Party shall notify the Indemnifying Party (with reasonable detail)
        promptly after it becomes aware of facts supporting a claim or action for
        indemnification under this Article
        IX,
        and
        shall provide to the Indemnifying Party as soon as practicable thereafter
        all
        information and documentation necessary to support and verify any Losses
        associated with such claim or action. Subject to Section
        9.2(c)(iv),
        the
        failure to so notify or provide information to the Indemnifying Party shall
        not
        relieve the Indemnifying Party of any liability that it may have to any
        Indemnified Party, except to the extent that the Indemnifying Party demonstrates
        that it has been materially prejudiced by the Indemnified Party’s failure to
        give such notice, in which case the Indemnifying Party shall be relieved
        from
        its obligations hereunder to the extent of such material prejudice. The
        Indemnifying Party shall participate in and defend, contest or otherwise
        protect
        the Indemnified Party against any such claim or action by counsel of the
        Indemnifying Party’s choice at its sole cost and expense; provided,
        however,
        that
        the Indemnifying Party shall not make any settlement or compromise without
        the
        prior written consent of the Indemnified Party (which consent shall not be
        unreasonably withheld or delayed) unless the sole relief provided is monetary
        damages that are paid in full by the Indemnifying Party. The Indemnified
        Party
        shall have the right, but not the obligation, to participate at its own expense
        in the defense thereof by counsel of the Indemnified Party’s choice and shall in
        any event use its reasonable best efforts to cooperate with and assist the
        Indemnifying Party. If the Indemnifying Party fails timely to defend, contest
        or
        otherwise protect against such suit, action, investigation, claim or proceeding,
        the Indemnified Party shall have the right to do so, including, without
        limitation, the right to make any compromise or settlement thereof, and the
        Indemnified Party shall be entitled to recover the entire cost thereof from
        the
        Indemnifying Party, including, without limitation, reasonable attorneys’ fees,
        disbursements and amounts paid as the result of such suit, action,
        investigation, claim or proceeding.

        INDEMNIFIED PARTIES, NOR SHALL ANY OF THE SELLING PARTIES BE LIABLE TO ANY

        irrevocably waive, to the fullest extent permitted by applicable law, any

        contemplated hereby brought in such court or any defense of inconvenient
