8.2.          Certain Loan Related Matters on the Completion Date

8.2.1        No fewer than five (5) Business Days prior to Completion, Sellers shall notify Buyer as to whether Section 8.2.1.1 or Section 8.2.1.2 (or a combination of both) shall apply on the Completion Date and/or thereafter as set forth in the notice:

At Completion, PRE Lender shall contribute to Newco, and Buyer shall procure that Newco accept, the 49 CEE Note and the 51 CEE Note, and upon such contribution (x) Newco’s liability to the Borrower under the Shareholder Note and (y) the Borrower’s liability to Newco under the 49 CEE Note and the 51 CEE Note, shall offset, and each of the Shareholder Note, the 49 CEE Note and the 51 CEE Note shall be automatically and finally cancelled and of no further force or effect, without any need for further action by any Person, it being understood and agreed that Buyer shall procure that Newco deliver any instrument or make any entry on its books or records as may be required to give effect to the foregoing contribution and offset transactions; or

36

8.2.1.2.             On the Completion Date, PRE Lender shall contribute the 49 CEE Note and the 51 CEE Note to Newco and, thereafter, Newco shall proceed as follows: (a) The 51 CEE Note shall be used by Newco to pay in kind the Carry Costs to BPZ E&P under the Carry Agreement and the JOA. Said payment in kind shall be made once the remaining amount of the 51 CEE Note is equal to the remaining balance of the Maximum Carry Amount. (b) At such time Newco shall also be entitled to use any remaining amount of the 49 CEE Note to pay in kind to BPZ E&P any future cash calls issued pursuant to the JOA with regard to its Participating Interest. By using the 51 CEE Note and the 49 CEE Note to pay in kind to BPZ E&P, respectively, the Carry Costs under the Carry Agreement and the JOA; and cash calls for its Participating Interest under the JOA, (i) BPZ E&P’s liability to the Borrower under the Shareholder Note and (ii) the Borrower’s liability to BPZ E&P under the 49 CEE Note and the 51 CEE Note shall offset, and each of the Shareholder Note, the 49 CEE Note and the 51 CEE Note shall be automatically and finally cancelled and of no further force or effect, without any need for further action by any Person, it being understood and agreed that Buyer shall procure that Newco deliver any instrument or make any entry on its books or records as may be required to give effect to the foregoing and offset transactions.

8.2.2        The Buyer (prior to Completion), or Newco (following Completion) shall be entitled to a credit from either the Government (under the application of Peruvian Value Added Tax Laws) or BPZ E&P related to VAT, as applicable, for all loans evidenced by the Shareholder Note which were made in connection with the 49 CEE Statements and the 51 CEE Statements, including the initial 49 CEE Statement and the initial 51 CEE Statement at such time as either (a) Newco is allowed to use such credit or, (b) in the case of BPZ E&P when BPZ E&P transfers such credit by including it in the Spin-Off.

8.3.          Payment Date Adjustments

8.3.1        On the Completion Date the Maximum Carry Amount shall be adjusted (with effect on the Payment Date) as follows:

8.3.1.1.             upward to reflect the share of Operating Expenses attributable to Newco’s deemed 49% Participating Interest, assuming that the JOA had been in effect during the period beginning on the Effective Date and ending on the Completion Date; and

8.3.1.2.             downward to reflect (i) any cash received attributable to Newco’s deemed 49% Participating Interest share of Hydrocarbons, and (ii) proceeds attributable to such Hydrocarbons, or calculated in accordance with the terms of the JOA produced or generated

37

during the period beginning on the Effective Date and ending on the Completion Date, or (iii) credits to the Joint Account, as defined in the JOA; and

8.3.1.3.             upward in an amount equal to the Peruvian income Tax (current and deferred) on the difference between the proceeds attributable to Newco’s 49% deemed Participating Interest as per Section 8.3.1.2 and the Operating Expenses attributable to Newco’s deemed 49% Participating Interest as per Section 8.3.1.1, solely for the period beginning on the Effective Date and ending on the Completion Date.

8.3.1.4.             to the extent that Sellers elect to use Section 8.2.1.1, downward, in an amount equal to the amount of the 51 CEE Note effectively cancelled under such Section.

8.3.2        If the adjustments to the Maximum Carry Amount taking place pursuant to Section 8.3.1 have the effect of rendering the Maximum Carry Amount a negative number on the Completion Date, the Parties shall settle such amount between them on the Completion Date (subject to further adjustment as required by this Agreement) by BPZ E&P paying to Newco in cash the amount by which the Maximum Carry Amount is less than zero.

8.4.          On-going Adjustment

8.4.1        On May 15 of each year, for the first five (5) years following the Completion Date, a downward adjustment to the Maximum Carry Amount will be made in the event that a real economic benefit is obtained by BPZ E&P because of the implementation of Section 8 of this Agreement during the Interim Period. Such real economic benefit will occur when:

(a)        the disbursements incurred by BPZ E&P with funds loaned by PRE Lender to Borrower and from Borrower to BPZ E&P under Section 8 hereof create a deductible expense for BPZ E&P’s corporate income tax purposes;

(b)        such expense has had the impact of reducing the income tax current annual obligation of BPZ E&P; and

(c)        after making a recalculation of the current income tax annual obligation of BPZ E&P and applying first all type of deductions, amortizations etc. to which BPZ E&P is entitled (apart from the expenses to which Section 8.4.1(a) hereof refers) as well as any existing BPZ E&P’s carry forward tax losses, the circumstance described in item (b) above is still present.

The Parties expressly recognize that neither Sellers nor BPZ E&P will be responsible, and hence Buyer will not have any right to an adjustment to

38

the Maximum Carry Amount if no real economic benefit is obtained by BPZ E&P after applying the above.

8.5.                              Resolution of Adjustments. In the event that the Parties cannot reach agreement within sixty (60) days, with respect to any adjustment set forth in Section 8, Sellers or Buyer may refer the adjustments in dispute to an internationally recognized independent accounting firm which has no affiliation for tax consulting, audit or other work for either Party as may be agreed by Buyer and Sellers, for review and final determination. The accounting firm shall act as an expert in accordance with Section 14.3 for the limited purpose of determining the specific disputed matters submitted by any Party and may not award damages or penalties to any Party with respect to any matter. The accounting firm’s determination shall be made within thirty (30) days after submission of the matters in dispute and shall be final and binding on both Parties, without right of appeal. Sellers and Buyer shall each bear its own legal fees, other costs of presenting its case, and one-half of the costs and expenses of the accounting firm.

8.6.                              Certain Tax Matters

8.6.1                        Taxes (other than Taxes measured by income, profits or capital gains), surface use fees, insurance premiums attributable to the Assets, Newco, or the Shares, and other Property Costs that are paid periodically shall be prorated based on the number of days in the period falling before the Effective Date, or on and after the Effective Date, as the case may be. The portion of Taxes allocated to the period before the Effective Date will not be included as part of the initial 49 CEE Statement delivered pursuant to Section 8.1.1.1 or the 51 CEE Statement delivered pursuant to Section 8.1.1.1 but Taxes attributable to the period on and after the Effective Date will be included in the 49 CEE Statements and 51 CEE Statements delivered pursuant to Section 8.1.1.2.

SECTION 9 - INDEMNITY

9.1.                              Indemnification Terms

9.1.1                        From and after the Signing Date, Sellers shall jointly and severally indemnify, save, hold harmless and defend the Buyer Parties and Newco from and against: (a) any and all claims, demands, causes of action, loss or damage arising from, or in connection with the Assets and the Shares that was incurred or derived from an event which occurred before the Signing Date or attributable to the period before the Signing Date; and (b) all Damages and/or Actions incurred by the Buyer Parties and Newco arising out of or resulting from any breach of any Warranty made by Sellers contained in Section 3.1 (and not disclaimed in Section 3.3), or breach of any obligation, covenant or agreement made by a Seller Party under this Agreement, or breach of any affirmations of such Warranties contained in the certificate delivered by Sellers at Completion pursuant to Section 7.1.2.5.

9.1.2                        From and after the Signing Date, and except as otherwise provided in this Agreement, Buyer shall indemnify save, hold harmless, and defend the Sellers Parties for all Damages and/or Actions incurred by Sellers arising out of or

Buyer shall also indemnify the Borrower as corporate guarantor under the License with respect to Newco’s Participating Interest for the period between Buyer’s acquisition of the Shares and Perupetro’s approval of the Buyer Guarantor as a replacement guarantor with respect to Newco’s Participating Interest, in the event that Perupetro instructs BPZ E&P, Buyer or a Buyer’s Affiliate that Buyer’s acquisition of the Shares is required in advance of the Government’s consideration of approving Buyer Guarantor as a replacement guarantor with respect to Newco’s Participating Interest. This indemnity obligation shall be supported by the Buyer Guarantee.

9.3.2        If the facts giving rise to a claim for indemnification involve an actual or threatened claim or demand by a third party against the Indemnified Party or a claim or demand by the Indemnified Party against a third party (Third Party Claim), the Indemnifying Party shall (without prejudice to the right of the Indemnified Party to participate at its expense through counsel of its own choosing) defend or prosecute the Third Party Claim in the name of the Indemnified Party at the Indemnifying Party’s expense and through counsel of its own choosing. The Parties shall cooperate in the defense or prosecution of the Third Party Claim and shall furnish such records, information and testimony and attend such conferences and discovery as reasonably requested in connection therewith.

9.3.3        Notwithstanding the Indemnifying Party’s obligation to assume and conduct the defense or prosecution of a Third Party Claim with counsel of its choice, the Indemnifying Party shall not consent to the entry of any judgment or enter into any settlement with respect to a Third Party Claim without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld) unless the judgment or proposed settlement involves only the payment of money Damages in an amount not more than $250,000.00, and does not impose an injunction or other equitable relief upon the Indemnified Party or any acknowledgment of the validity of the Third Party Claim. Until the Indemnifying Party assumes the defense or prosecution of a Third Party Claim, the Indemnified Party may at the expense of the Indemnifying Party defend against the Third Party Claim in any manner it deems reasonably appropriate; provided that in no event shall the Indemnified Party consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld).

9.4.2.3.              the Claim is for (i) the subject matter of which is covered by any insurance policy for the benefit of a Buyer Party, its Affiliates or Newco with respect to which a claim has been paid, it being understood and agreed. Buyer shall and shall procure that it and its Affiliates at all times maintain in full force and effect the corporate level and similar insurance policies in effect as of the Signing Date.

9.4.2.4.              the subject of the claim has been or is made good or is otherwise compensated for without cost to the Buyer Parties; or

9.5.2        Except with respect to the Claims set forth in Sections 9.5.1.1, 9.5.1.2, and 9.5.1.3 for which there shall be no minimum Claim amount, no liability shall attach to the Seller in respect of a Claim unless and until the aggregate amount of the liability in respect of all Claims exceeds $2,000,000.00 and:

STEP PLAN AND TRANSFER MEMORANDUM

Please note that the attached Step Plan and Transfer Memorandum will be amended by agreement of the Parties and per comments from the Parties’ Peruvian counsel.

STEP PLAN AND TRANSFER MEMORANDUM

1.                              BPZ E&P Spin-off shall be conducted in accordance with item 2 of Article 367 of Peruvian Corporations General Law N° 26887(“CGL”), the article provides the following:

“Article 367 — Spin off: Concept and forms

Through a spin off, a company divides its net worth into two or more blocks in order to fully transfer them to other companies or to conserve one of them, complying with the requirements and the formalities contained in this Act. The Spin off can adopt any of the following forms:

1.                              The division of a company’s total net worth in two or more net worth blocks, which are transferred to new companies or absorbed by existing companies, or by both new companies and existing companies at once. This form of spin off produces the extinction of the company that transfers the net worth blocks; or,

2.                              The segregation of one or more net worth blocks of a company that does not extinguish, and which are transferred to one or more new companies, or absorbed by existing companies or by both new companies and existing companies at once. The company that transfers the net worth blocks adjusts its share capital in the corresponding amount.

In both of the above cases, the partners or shareholders of the company that transfers the net worth blocks receive shares as partners or shareholders of the new companies or of the absorbing companies, whichever the case.”

2.                              In order to comply with the CGL, after execution of the Stock Purchase Agreement (“SPA”), the shareholders of BPZ E&P and BPZ Norte Oil (“Newco”) shall approve the Spin-off, as defined in the SPA, based on the Spin-off plan prepared and approved by BPZ E&P and Newco general managers. The Spin-off plan shall include, among others, a description of the net worth block to be transferred; Newco’s capital increase and BPZ E&P capital reduction in the amount of the net worth block’s net book value as of the Spin-off effective date; the number of shares to be issued by Newco and distributed between the shareholders of BPZ E&P (“Sellers”) as a result of the capital increase; and, the effective date of the Spin-off.

3.                              The Spin-off shall become effective on the date of the public deed amending the License to include Newco as a party to the License with a 49% Participating Interest (“License DOT”), which is the Completion Date in the SPA (“Completion Date”). (This assumes that the Supreme Decree including Newco’s interest in the License also approves Buyer Guarantor’s guarantee , if not, (a) the Completion Date shall be the date of the public deed amending the License to include Buyer Guarantor as Newco’s corporate guarantor (“Second License DOT”) after Supreme Decree approving Buyer Guarantor’s guarantee is

issued, and (b) every reference to Completion Date hereinafter shall be deemed to be the License DOT date.)

4.                              The Spin-off details are as follows:

a.                                The net worth block to be segregated from BPZ E&P and transferred to Newco includes: (i) an undivided 49% Participating Interest in the License; (ii) an undivided 49% of all assets and other rights related to the License; and (iii) all other assets and liabilities to be included in the net worth block by BPZ E&P and Newco prior to the Completion Date.

Said exhibit consist on a list of all assets registered in BPZ E&P Peruvian accounting books, related to the License operations, and the value of each assets shall be its 49% book value.

The assets list shall be prepared using BPZ E&P accounting as of December 31, 2011 and will be updated prior to Completion Date.

c.                                The other assets and liabilities to be included in the net worth block prior to Completion Date shall consist on those items described in Section 8.2.1.1 of the SPA. as well as BPZ E&P’s liabilities to the Borrower for the loans made by the Borrower pursuant to the SPA and the related Value Added Tax subject to terms of Section 8.2.2 of the SPA.

The Maximum Carry Amount may be adjusted at Completion Date pursuant to Section 8.2.1.2 of the SPA.

e.                                (Note: we don’t need the deleted portion of this paragraph because everything is in paragraphs 7 and 12 below) The Spin-off shall also specify the number of shares representing Newco’s capital increase, equal to the net book value of the net worth block as of December 31, 2011 which shall be updated prior to the Completion Date.
