(ii) “ERISA” shall mean the Employee Retirement Income Security Act of 1974, as amended.

(iii) “GP Entity Plan” means each material Plan that any of the GP Entities sponsors, maintains or contributes to, or to which any of the GP Entities have an obligation to contribute, within six years prior to the date of this Agreement, other than any Equity Plan.

(iv) “Plan” means any of the following: any “employee benefit plan” (within the meaning of Section 3(3) of ERISA), any plans that would be employee benefit plan if it were subject to ERISA, such as foreign plans and plans for directors, stock option or other equity or equity-related compensation plan, stock purchase plan, bonus program, incentive plan, cafeteria or flexible benefit plan, deferred compensation arrangement, and all other similar employee benefit plans, programs, arrangements, policies, or agreements. For the avoidance of doubt, a Person is not considered to sponsor, maintain, contribute to or have an obligation to contribute to a “Plan” solely by virtue of being a party to an administrative services or similar agreement that requires the Person to reimburse another Person with respect to expenses incurred under a Plan sponsored, maintained or contributed to by that other Person.

(v) “Equity Plan” or “Equity Plans” means each material compensation plan or employment agreement under which any employee, director or consultant of BreitBurn Management has received an award of incentive compensation (including, without limitation, options, unit appreciation rights, restricted phantom units, and performance units) with respect to, or related to the value of, the Partnership, BECLP, BreitBurn Management or any of their respective Affiliates.

(b) To the Knowledge of the Selling Parties, Schedule 3.13(b) lists each Equity Plan. For the avoidance of doubt, (i) the listing on Schedule 3.13(b) includes any employment agreements that describe equity or equity-based incentive awards that were not granted under any compensation plan applicable to any group or class of employees (such as phantom options granted pursuant to executive employment agreements), (ii) other than with respect to any such employment agreements, such listing does not describe individual award agreements entered into pursuant to the Equity Plans, and (iii) the individual award agreements entered into pursuant to the Equity Plans are included in the definition of “Equity Plans” for purposes of this Agreement despite the fact that they are not specifically listed on Schedule 3.13(b).

(c) There does not now exist, nor do any circumstances exist that could result in, any Controlled Group Liability of the Selling Parties or any ERISA Affiliate of the Selling Parties arising out of or in connection with any Provident Plan that would be, or could become, a liability following the Closing of the GP Entities, the Partnership or any of their ERISA Affiliates.

Section 3.14 No Other Representations. Except as and to the extent set forth in this Article III, neither of the Selling Parties nor any other Person makes any representations or warranties whatsoever to Buyer, and the Selling Parties hereby disclaim all liability and responsibility for any representation, warranty, statement, or information made, communicated, or furnished (orally or in writing) to Buyer or its Affiliates or representatives (including any opinion, information, projection, or advice that may have been or may be provided to Buyer by any director, officer, employee, agent, consultant, or representative of either of the Selling Parties or any Affiliate thereof) other than as and to the extent set forth in this Article III. Neither of the Selling Parties nor any other Person makes any representations or warranties to Buyer regarding the probable success or profitability of either of the GP Entities or their respective businesses, individually or on a consolidated basis.

(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).

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.

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.

Section 5.9 Post-Closing Post Closing Payments to Selling Parties and Affiliates.
