OPERATIONS AND PROCEEDS AGREEMENT

This Operations and Proceeds Agreement (this “Agreement”) is entered into this 10th day of October, 2006, by and between BreitBurn Energy Company L.P. (“Owner-Operator”) and BreitBurn Operating L.P. (“Counterparty”).  Owner-Operator and Counterparty are sometimes collectively referred to herein as the “Parties” and individually as a “Party.”

WITNESSETH

WHEREAS, references is made to that certain Contribution, Conveyance and Assumption Agreement dated October 10, 2006 (the “Contribution Agreement”) in connection with that certain MLP transaction and related public offering (the “Transaction”), pursuant to which Owner-Operator has agreed to assign certain Non-Consent Assets (as defined in the Contribution Agreement) to Counterparty as a capital contribution, and in exchange for an assumption by Counterparty of Owner-Operator’s debt, only upon the receipt of certain consents with respect thereto; and

WHEREAS, pending the receipt of such consents, Owner-Operator has agreed to continue to hold title and all other interest in and to such Non-Consent Assets and to enter into this agreement with Counterparty with respect to the conduct of operations and the allocation of income, cost and liability thereunder; and

WHEREAS, entering into this Agreement will further the Transaction for the mutual benefit of the Parties;

NOW, THEREFORE, for and in consideration of the benefits herein contained and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows:

ARTICLE I
OPERATIONS

1.1          Operations.  During the term of this Agreement, Owner-Operator shall conduct all operations with respect to the oil and gas leases and other properties more particularly described in Exhibit A hereto (the “Leases”) and all other assets (including hydrocarbons), contracts and interests held in connection therewith or produced therefrom (collectively with the Leases, the “Lease Assets”) (such operations being herein referred to as the “Lease Operations”) as instructed by Counterparty from time to time.

1.2          Notification.  Owner-Operator shall, as soon as reasonably practicable, notify Counterparty of:

(a)           any material adverse change to the Lease Assets or any event that, with the passage of time or otherwise, is reasonably likely to result in a material adverse change to the Lease Assets;

1

(b)           Owner-Operator becoming aware of any violation of law or breach of contract (or assertion alleging same) involving the Lease Assets or Lease Operations; and

(c)           any asserted claim or demand with respect to the Lease Assets or Lease Operations or for which Counterparty could bear ultimate financial responsibility or liability under the terms hereof or otherwise.

1.3          Standard of Care.  Owner-Operator shall conduct the Lease Operations, and maintain the Lease Assets, as would a reasonable and prudent operator.  If at any time Owner-Operator determines that complying with Counterparty’s instructions hereunder would be inconsistent with the standards of a reasonable and prudent operator, Owner-Operator shall promptly notify Owner-Operator of its specific concerns and the Parties shall agree on how to proceed but failing such agreement Owner-Operator shall proceed as instructed by Counterparty; provided that Owner-Operator shall never be obligated to violate any law or any good industry standard for protecting health, safety and the environment and provided that Counterparty shall fully release, indemnify and hold harmless Owner-Operator from any loss, cost, expense, damage or liability arising from such action(s) (other than to the extent resulting from Owner-Operator’s gross negligence or willful misconduct) regardless of simple negligence or strict liability.

ARTICLE II
ACCOUNTING

2.1          Accounts.  Owner-Operator shall maintain an accounting, in accordance with prudent and accepted accounting practices and separately for each operating property subject to this Agreement, of all income actually received (“Lease Income”) and all costs actually paid (“Lease Costs”), in each case as attributable to its interest in the Lease Assets and taking into account any pre-payments by Counterparty under Section 2.5 (the “Lease Accounting”).

2.2          Statements.  As requested by Counterparty, but no more often than monthly, during the term of this Agreement Owner-Operator shall prepare and deliver to Counterparty a statement setting forth the Lease Accounting for such requested period (each, an “Accounting Statement”), including such supporting material as is reasonably necessary to document same, or as Counterparty may reasonably request, and indicating whether, and the extent to which, Lease Income exceeded Lease Costs for such period (a “Net Profit”) or vice versa (a “Net Loss”).  On at least a monthly basis, Owner-Operator shall compute the Net Profit or the Net Loss attributable to each operating property subject to this Agreement.  Owner-Operator shall obtain the consent of Counterparty for any non-recurring expenses or any costs outside normal operations in connection with the Lease Operations in excess of $25,000.

2.3          Payment.  With respect to each month for which there is a Net Profit, Owner-Operator shall pay Counterparty, on or before the 25th day of the following month, an amount equal to such Net Profit.  With respect to each month for which there is a Net Loss, Counterparty shall pay Owner-Operator, on or before the 25th day of the following month, an amount equal to such Net Loss.  All payments hereunder shall be to accounts of the Parties as indicated to each other in writing from time to time.

2

2.4          Operating/Reserve Accounts.  Notwithstanding the obligation of Owner-Operator to pay to Counterparty the Net Profit for each month, Owner-Operator shall, during the term of this Agreement until the final Accounting Statement issued in connection with the termination of this Agreement, be entitled to maintain from month to month, an account containing a balance reasonably approximating the following month’s anticipated expenses with respect to the Lease Operations and a reasonable emergency reserve (not exceeding five month’s operating expenses with respect to the Lease Operations).

2.5          Pre-Payments.  If Owner-Operator determines, acting reasonably, that any Lease Cost anticipated for the following month is likely to result in a Net Loss for such month, it shall promptly notify Counterparty of same and Counterparty shall use reasonable endeavors to pay such Lease Cost to Owner-Operator in advance of same being paid by Owner-Operator.

ARTICLE III
INFORMATION ACCESS

3.1          Access.  Owner-Operator shall:

(a)           permit Counterparty to observe Lease Operations, have access to the Lease Assets and inspect all files, records and contracts related thereto; and

(b)           timely provide Counterparty such information as it may reasonably need (as determined by Owner-Operator acting in good faith), or as Counterparty may reasonably request from time to time, in order to (i) be fully and fairly informed as to the state of the Lease Assets and the Lease Operations conducted and to be conducted, (ii) make reasonably informed decisions with respect to instructions for Lease Operations or disposition of the Lease Assets, and (iii) fully document Lease Operations, Lease Costs and Lease Income hereunder;

in each case except to the extent prohibited by applicable confidentiality restrictions or other contractual or legal obligations.  Owner-Operator shall reasonably cooperate with Counterparty’s access to and inspection of such information and the Lease Assets and Counterparty shall not unreasonably interfere with the operations and activities of Owner-Operator.

3.2          Audit.  Counterparty shall have the right, at reasonable intervals and at is own expense, to audit Owner-Operator’s books and records to confirm compliance with the terms of this Agreement; provided that if any such audit conclusively identifies material errors on the part of Owner-Operator, the expense of such audit shall be for the account of Owner-Operator (notwithstanding Section 5.2).

ARTICLE IV
ASSIGNMENT

4.1          Assignment.  Owner-Operator shall continue to use commercially reasonable efforts to obtain all necessary consents for the contribution of the Lease Assets; provided however that nothing in this Agreement shall require Owner-Operator to incur or agree to incur any liability or cost, or to make any payment, in conjunction with obtaining such consent.  Upon

3

the receipt of all such necessary consents, the Parties shall execute the Assignment (as defined in the Contribution Agreement) with respect to the Leases and either Party shall have the right to cause same to be recorded of record, and this Agreement shall terminate in accordance with Section 6.1(a).

4.2          Title.  Nothing in this Agreement shall be construed as conveying title to or any interest in the Leases, all of which, until such time as the Assignment executed pursuant to Section 4.1 shall become effective, shall remain solely with Owner-Operator.  Should any provision of this Agreement be construed as conveying an interest in the Leases, where such construction would result in a termination, breach or release of the Leases, then such provision shall be null and void ab initio and of no force or effect.  If any such nullified provision alters the overall economic effect between the Parties hereunder, the Parties shall use good faith efforts to amend this Agreement to create the economic effect that would have existed but for such nullification.

ARTICLE V
INDEMNIFICATION

5.1          Owner-Operator Indemnification.  Owner-Operator shall release, defend, indemnify and hold harmless Counterparty from and against any and all loss, cost, expense, damage and liability arising out of or related to the Lease Operations or the ownership or operation of the Lease Assets, in each case (i) to the extent resulting from Owner-Operator’s breach of this Agreement, gross negligence or willful misconduct or (ii) to the extent attributable to periods prior to the date hereof.

5.2          Counterparty Indemnification.  Counterparty shall release, defend, indemnify and hold harmless Owner-Operator from and against any and all loss, cost, expense, damage and liability arising out of or related to the Lease Operations or the ownership or operation of the Lease Assets (other than to the extent of Owner-Operator’s indemnification set forth in Section 5.1 above) to the extent attributable to periods from and after the date hereof.

ARTICLE VI
TERMINATION

6.1          Termination.  This Agreement shall terminate upon the first to occur of:

(a)           the Assignment executed pursuant to Section 4.1 becoming effective in accordance with its terms;

(b)           Owner-Operator and Counterparty ceasing to be Affiliates; and

(c)           Owner-Operator and Counterparty mutually agree in writing to such termination.

4

that beneficially owns, holds or controls 50% or more of the interest of such first mentioned person or entity, or (iii) for which 50% or more of the interest therein is beneficially owned, held or controlled by such first mentioned person or entity.

6.2.         Final Accounting Statement.  Upon termination of this Agreement, Owner-Operator shall promptly deliver to Counterparty a final Accounting Statement effective as of the date of such termination (taking into account the balance of any reserve or operating accounts existing as of the date of such termination) and the Parties shall promptly pay any final Net Profits or Net Loss in accordance with the terms of Section 2.3.

6.3          Survival.  Notwithstanding the termination of this Agreement, Section 6.2 shall survive until such time as the Parties have fulfilled their obligations thereunder; Section 2.3 shall survive to the extent required for the effectiveness of Section 6.2; Section 3.2 shall survive for a period of 1 year; Sections 5.1 and 5.2 shall survive indefinitely; and this Section 6.3 shall survive to the extent necessary to give effect to terms hereof.

ARTICLE VII
MISCELLANEOUS

7.1          Choice of Law.  This Agreement shall be governed by the laws of the State of California without regard to choice of law principles that would apply the laws of another jurisdiction.

7.2          Severability.  If any provision of this Agreement contravenes, or is unenforceable under, applicable laws such provision shall be deemed severable and of no force or effect to the extent of such contravention or unenforceability but all other provisions hereof shall nevertheless remain in full force and effect. If any such severed provision alters the overall economic effect between the Parties hereunder, the Parties shall use good faith efforts to amend this Agreement to create the economic effect that would have existed but for such severing.

7.3          Assignments.  Neither Party shall assign this Agreement without the express prior written consent of the other Party.  Owner-Operator shall not assign the Leases without the express prior written consent of Counterparty.

5

7.4          Headings.  The headings of Articles and Sections of this Agreement are used for convenience of reference only and shall not limit or affect the legal construction of any provision hereof.

EXHIBIT C

SURFACE OPERATING AGREEMENT

SURFACE OPERATING AGREEMENT

This Surface Operating Agreement (this “Agreement”) is entered into this 10th day of October, 2006, by and between BreitBurn Energy Company L.P. and its predecessor BreitBurn Energy Corporation (collectively “Surface Operator”) and BreitBurn Operating L.P. (“Owner”).  Surface Operator and Owner are sometimes collectively referred to herein as the “Parties” and individually as a “Party.”

WITNESSETH

WHEREAS, reference is made to that certain Contribution, Conveyance and Assumption Agreement dated October 10, 2006, in connection with that certain MLP transaction and related public offering (the “Transaction”), pursuant to which Surface Operator has assigned that certain oil and gas lease more particularly described in Exhibit A (the “Lease”) to Owner as a capital contribution and in exchange for an assumption by Owner of Surface Operator’s debt; and

WHEREAS, reference is made to that certain Agreement between United States of America and Hancock Oil Company dated the 19th day of August, 1954, pursuant to which Surface Operator, as successor in interest to Hancock Oil Company, has the right to conduct operations on the surface of the lands covered by the Lease (the “Surface Use Agreement”); and

WHEREAS, assignment of the Surface Use Agreement requires the prior written consent of the government, which consent has not yet been obtained as of the date of the closing of the Transaction; and

WHEREAS, pending the receipt of such consent, Surface Operator has agreed to continue to conduct all operations with respect to such Lease to the extent requiring access to the surface of the lands governed by the Surface Use Agreement in consideration for Owner assuming all obligations of Surface Operator thereunder, all in accordance with the terms hereof; and

WHEREAS, entering into this Agreement will further the Transaction for the mutual benefit of the Parties;

NOW, THEREFORE, for and in consideration of the benefits herein contained and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows:

ARTICLE I
OPERATIONS

1.1          Operations.  During the term of this Agreement, Surface Operator shall conduct such operations with respect to the Lease and all other assets (including hydrocarbons), contracts and interests held in connection therewith or produced therefrom (collectively with the Lease, the “Lease Assets”) to the extent requiring access to the surface of the lands covered by, or

2

otherwise related to or arising under, the Surface Use Agreement (such operations being herein referred to as the “Surface Operations”), if any, as instructed by Owner from time to time.

1.2          Standard of Care.  Surface Operator shall conduct the Surface Operations in a good and workmanlike manner in accordance with all applicable laws and good industry standards for protecting health, safety and the environment.  If at any time Surface Operator determines that complying with Owner’s instructions hereunder would be inconsistent with such standards, Surface Operator shall promptly notify Surface Operator of its specific concerns and the Parties shall agree on how to proceed, but failing such agreement Surface Operator shall proceed as instructed by Owner; provided that Surface Operator shall never be obligated to violate any law or any good industry standard for protecting health, safety and the environment and provided that Owner shall fully release, indemnify and hold harmless Surface Operator from any loss, cost, expense, damage or liability arising from such action(s) (other than to the extent resulting from Surface Operator’s gross negligence or willful misconduct in conducting Surface Operations) regardless of simple negligence or strict liability.

ARTICLE II
ACCOUNTING

2.1          Invoices.  The Parties shall use reasonable efforts to cause all third party invoices for services rendered in connection with the Surface Operations (each, a “Third Party Invoice”) to be delivered directly to Owner for payment.  Surface Operator shall promptly forward to Owner all Third Party Invoices it receives, in order for Owner to have sufficient time to pay same, together with such supporting material as is reasonably necessary to document any Third Party Invoice or as Owner may reasonably request. Surface Operator shall obtain the consent of Owner for non-recurring expenses or any costs outside the ordinary operations in connection with the Surface Operations in excess of $25,000.

2.2          Out of Pocket Expenses.  Owner shall reimburse Surface Operator on a monthly basis for all direct and indirect expenses including reasonable overhead and indirect costs, incurred by Surface Operator in conducting operations on behalf of Owner hereunder.  Such reimbursement shall be determined pursuant to the Administrative Services Agreement by and among Owner, Surface Operator and BreitBurn Management Company, LLC, or its equivalent, as amended from time to time.  If Surface Operator reasonably incurs any direct out-of-pocket expenses in connection with conducting the Surface Operations during a given month, Owner shall reimburse Surface Operator as follows.  With respect to the reimbursement of operating costs or out-of-pocket expenses, Surface Operator shall, within 30 days following the end of such month, prepare and deliver to Owner an invoice setting forth the amount of such expenses, including such supporting material as is reasonably necessary to document same, or as Owner may reasonably request.  Owner shall pay Surface Operator, within 15 days following receipt of such invoice, all amounts set forth therein other than amounts subject to a good faith dispute among the Parties.  All payments to Surface Operator hereunder shall be to the account it designates in writing from time to time.

ARTICLE III
REPORTING

3.1          Reporting.  Surface Operator shall timely provide Owner such information as it may reasonably need (as determined by Surface Operator acting in good faith), or as Owner may reasonably request from time to time, in order to (i) be fully and fairly informed as to the Surface Operations, (ii) make reasonably informed decisions with respect to instructions for changes to or additional Surface Operations, and (iii) fully document Surface Operations, operating fee, Third Party Invoices and Direct Expenses hereunder.  Without limiting the generality of the foregoing, Operator shall, as soon as reasonably practicable following becoming aware of same in connection with conducting the Surface Operations, notify Owner of:

(a)           any material adverse change to the Lease Assets or any event that, with the passage of time or otherwise, is reasonably likely to result in a material adverse change to the Lease Assets;

(b)           any violation of law or breach of contract (or assertion alleging same) involving the Lease Assets or Surface Operations; and

(c)           any asserted claim or demand with respect to the Lease Assets or Surface Operations or for which Owner could bear ultimate financial responsibility or liability under the terms hereof or otherwise.

ARTICLE IV
SURFACE USE ASSIGNMENT

4.1          Consent.  Surface Operator shall take such steps as the Parties shall mutually agree for the purposes of obtaining all necessary consents to assign the Surface Use Agreement to Owner.

4.2          No-Conveyance.  Nothing in this Agreement shall be construed as conveying the Surface Use Agreement to Owner, which, until such time as all necessary consents have been received, shall remain solely with Surface Operator.  Should any provision of this Agreement be construed as conveying the Surface Use Agreement, where such construction would result in a termination, breach or release of the Surface Use Agreement, then such provision shall be null and void ab initio and of no force or effect.  If any such nullified provision alters the overall economic effect between the Parties hereunder, the Parties shall use good faith efforts to amend this Agreement to create the economic effect that would have existed but for such nullification.

ARTICLE V
ASSUMPTION AND INDEMNIFICATION

5.1          Assumed Obligations.  Owner hereby assumes all costs and liabilities of Surface Operator or any predecessors in interest, including costs and liabilities attributable to

4

abandonment, operations, plugging and remediation, arising under the Surface Use Agreement (the “Assumed Obligations”).

5.2          Indemnification.  Owner shall release, defend, indemnify and hold harmless Surface Operator from and against any and all loss, cost, expense, damage and liability (including but not limited to reasonable attorney’s fees) arising out of or related to the Surface Operations, the Surface Use Agreement or the ownership of the Lease, including without limitation all Assumed Obligations (other than to the extent resulting from Surface Operator’s material breach of this Agreement, or gross negligence or willful misconduct in conducting Surface Operations), regardless of Surface Operator’s simple negligence or strict liability.

ARTICLE VI
TERMINATION

6.1          Termination.  This Agreement shall terminate upon the first to occur of:

(a)           the assignment by Surface Operator to Owner of the Surface Use Agreement following the receipt of all consents necessary therefor;

(b)           Surface Operator and Owner ceasing to be Affiliates; and

(c)           the Owner and Surface Operator mutually agree in writing to such termination.

For purposes of this Section, “Affiliate” shall mean, with respect to a given person or entity, any other person or entity (i) that directly or indirectly (through one or more intermediaries) controls, or is controlled by, or is under common control with, such first mentioned person or entity, (ii) that beneficially owns, holds or controls 50% or more of the interest of such first mentioned person or entity, or (iii) for which 50% or more of the interest therein is beneficially owned, held or controlled by such first mentioned person or entity.

6.2          Survival.  Article V shall survive the termination of this Agreement.

ARTICLE VII
MISCELLANEOUS

7.1          Choice of Law.  This Agreement shall be governed by the laws of the State of California without regard to choice of law principles that would apply the laws of another jurisdiction.

7.2          Severability.  If any provision of this Agreement contravenes, or is unenforceable under, applicable laws such provision shall be deemed severable and of no force or effect to the

5

extent of such contravention or unenforceability but all other provisions hereof shall nevertheless remain in full force and effect. If any such severed provision alters the overall economic effect between the Parties hereunder, the Parties shall use good faith efforts to amend this Agreement to create the economic effect that would have existed but for such severing.

7.3          Assignments.  Neither Party shall assign this Agreement without the express prior written consent of the other Party.

7.4          Headings.  The headings of Articles and Sections of this Agreement are used for convenience of reference only and shall not limit or affect the legal construction of any provision hereof.

IN WITNESS WHEREOF, the Parties have executed this Agreement as of the day and year first above written.
