CONSIDERATION

Section 2.1 Consideration. The consideration for the Assets under this Agreement shall be the Cash Consideration and the Common Units Consideration (the Cash Consideration and the Common Units Consideration together, the “Consideration”).

Section 2.5 Closing Settlement Statement. No later than five Business Days before the Closing Date, AEO shall deliver to BreitBurn a draft settlement statement setting forth its calculation of the Adjusted Cash Consideration (the “Closing Settlement Statement”), which statement shall be substantially in the form of Exhibit I and which shall reflect each adjustment made in accordance with this Agreement as of the date of preparation of such Closing Settlement Statement and the calculation of the adjustments used to determine such amount.

(a) Parent has filed all reports, schedules, forms, statements and other documents (including exhibits and other information incorporated therein) required to be filed by Parent with the Securities and Exchange Commission (“SEC”) since January 1, 2012 (such documents being collectively referred to as the “Parent SEC Reports”). Each Parent SEC Report (i) at the time filed or, if amended, as of the date of such amendment, complied as to form in all material respects with the applicable requirements of the Exchange Act and the Securities Act, as the case may be, and the rules and regulations of the SEC promulgated thereunder applicable to such Parent SEC Report and (ii) did not, at the time it was filed (or, if amended or superseded by a filing or amendment prior to the date hereof, then at the time of such filing or amendment) contain any untrue statement of a material fact or omit to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 light of the circumstances under which they were made, not misleading.

(b) The financial statements contained in the Parent SEC Reports (i) have been prepared in accordance with GAAP, applied on a consistent basis throughout the periods presented thereby (except as may be indicated in the notes thereto or, in the case of unaudited financial statements, as permitted by Form 10-Q of the SEC), and (ii) fairly present, in all material respects, the consolidated financial position and operating results, equity and cash flows of Parent and its Subsidiaries, on a consolidated basis, as of, and for the periods ended on, the respective dates thereof, subject, however, in the case of unaudited financial statements, to normal, recurring and year-end audit adjustments.

Such disclosure controls and procedures are reasonably designed to ensure that all material information required to be disclosed by Parent and its subsidiaries in the reports that it files or furnishes under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that all such material information is accumulated and communicated to Parent’s management as appropriate to allow timely decisions regarding required disclosure and to make the certifications required pursuant to Sections 302 and 906 of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 (the “▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act”).

Parent does, and reasonably expects to continue to, meet the gross income requirements of Section 7704(c)(2) of the Code, and 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 10.4 Indemnification by BreitBurn.

(a) General Indemnity from BreitBurn; Assumed Obligations. Except to the extent AEO has an indemnification obligation under Section 10.3, upon Closing, BreitBurn shall defend, indemnify and hold harmless AEO, its affiliates and its successors and permitted assigns and their respective shareholders, members, partners (general and limited), officers, directors, managers, employees, agents and representatives (collectively, the “AEO Indemnified Parties”), from and against and in respect of any and all Damages to the extent arising out of or related to:

(i) the ownership or operation of any of the Assets by BreitBurn on or after the Closing Date and the Assumed Obligations in each case effective as of the Effective Time (“BreitBurn’s Indemnification Period”);

(ii) any breach of any representation or warranty (other than any of BreitBurn’s Fundamental Representations) made by BreitBurn in Article 6 or in any certification in the certificate delivered by BreitBurn to AEO at Closing pursuant to Section 8.3(c); provided that for purposes of determining whether any representations and warranties have been breached, all materiality qualifications contained in such representations and warranties shall be disregarded;

(iii) any breach of any Fundamental Representation made by BreitBurn or in any certification in the certificate delivered by BreitBurn to AEO at Closing pursuant to Section 8.3(c); provided that for purposes of determining whether any representations and warranties have been breached, all materiality qualifications contained in such representations and warranties shall be disregarded; and

(iv) any breach of any covenant, agreement or undertaking made by BreitBurn in this Agreement.

(b) Limitations on BreitBurn’s Indemnity Obligations. The obligation to indemnify AEO Indemnified Parties set forth in Section 10.4(a) shall be subject to each of the following limitations:

(i) BreitBurn’s indemnification obligations under Section 10.4(a)(i) and Section 10.4(a)(iii) shall survive without the limitation of time;

(ii) BreitBurn’s indemnification obligations under Section 10.4(a)(ii) shall survive until the date that is eighteen months from the Closing Date;

(iii) BreitBurn’s indemnification obligations under Section 10.4(a)(iv) shall survive to the extent the covenants, agreements or undertakings referred to therein are (A) performable on or prior to Closing, the indemnification obligations shall survive until the date that is eighteen months following the Closing or (B) performable after Closing, the indemnification obligations shall continue for the period specified with respect to such covenant or, if no such period is specified, until such covenant, agreement or undertaking is fully performed; and

(iv) To the extent that AEO or AEO Indemnified Parties timely assert indemnification claims for Damages which individually meet or meet or exceed the De Minimis AEO Losses (each, a “Material Claim,” and, collectively, the “Material Claims”), BreitBurn shall have no indemnification, reimbursement or payment obligations for any Damages pursuant to Section 10.4(a)(ii) (except with regard to Section 6.5), in excess of an amount equal to 20% of the Consideration.

(c) Exclusive Remedy. The indemnities provided in this Section 10.4 shall survive Closing, as contemplated in Sections 10.4(b)(i)-(iv). The indemnity provided in this Section 10.4 shall be the sole and exclusive remedies of AEO and any other AEO Indemnified Parties from and after Closing against BreitBurn, at law, in equity or otherwise, relating to this Agreement (including any alleged breach hereof) or the transactions contemplated hereby.

(d) Claim Procedures. AEO 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 10.4, 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 AEO within sixty days of receipt of AEO’s written notice; provided, however, that BreitBurn’ counsel shall be reasonably satisfactory to AEO. Failure to give prompt notice shall not affect the indemnification obligations hereunder in the absence of actual prejudice. If AEO 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 AEO, 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 AEO shall give BreitBurn written notice thereof and, if BreitBurn does not take reasonable action to remedy such failure within thirty days after receipt, then AEO may assume such defense and BreitBurn shall continue to be liable for all reasonable costs and expenses incurred in defending such actions, provided that AEO 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 AEO Indemnified Party, settle any action or claim against such AEO Indemnified Party or consent to the entry of any judgment with respect thereto that (i) does not result in a final resolution of the AEO Indemnified Party’s liability with respect to such action or claim (including, in the case of a settlement, an unconditional written release of the AEO 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 AEO Indemnified Party, other than conduct which violates a Law.
