Smithfield, OCM and the Company will each submit to the Independent Accounting Firm a written statement setting forth such party’s calculation of the Final Company EBITDA. The Independent Accounting Firm will select one, and only one, party’s calculation as the Final Company EBITDA. The Independent Accounting Firm shall be instructed to use every reasonable effort to perform its services within thirty (30) days of submission of the calculations to it and, in any case, as promptly as practicable after such submission and the Independent Accounting Firm’s determination of the Final Company EBITDA shall be final and binding on the parties. Any expenses relating to the engagement of the Independent Accounting Firm shall be paid pro rata by each of the parties whose proposed calculation of the Final Company EBITDA was not chosen by the Independent Accounting Firm as the Final Company EBITDA. Each party shall pay all advisors’ fees, charges and expenses incurred by such party in connection with the dispute.

(b) Determination of the Premium.

(i) In the event that the Final Company EBITDA exceeds the Company’s Target EBITDA (as set forth in the table below), EPOF and OPPS shall pay to the Company an aggregate Premium (plus any applicable “equity contribution” tax in an amount not to exceed one percent (1%) of the Premium) (collectively, the “Additional OCM Contribution”)as allocated between them pursuant to Section 3(b)(ii) below, for the ordinary shares (“participaciones”) referred to in Section 2(b) and 2(c), as determined in accordance with the following table:

provided that, OCM and the Company hereby agree to negotiate, in consultation with Smithfield, in good faith, to make any adjustments in the Company’s Target EBITDA set forth above to the extent any such adjustment may be necessary to reflect any acquisition, disposition or restructuring affecting the Company’s operations.

(ii) EPOF shall be obligated to pay to the Company sixty-eight and sixty-two hundreths percent (68.62%) of any Premium and OPPS shall be obligated to pay to the Company thirty-one and thirty-eight hundreths percent (31.38%) of any Premium. Notwithstanding the foregoing, the obligations of each of EPOF and OPPS to pay to the Company the Additional OCM Contribution, plus all accrued and unpaid interest thereon, shall be the joint and several obligations of such parties.

4. Interest Rate. The Premium shall be deemed to bear interest from the date hereof until paid in full at a rate of 4.0% per annum, compounded annually. Such interest shall be due and payable pursuant to the terms of Section 5 of this Agreement. If an Event of Default shall occur, then all amounts then outstanding under the Premium shall thereafter bear interest at 3.0% plus the rate otherwise in effect immediately upon such Event of Default. Accrued interest shall be computed for actual days elapsed on the basis of a year of 365 days.

5. Payments. The outstanding sum of the applicable Premium plus all accrued and unpaid interest thereon shall be due and payable promptly after the determination of the Premium, but in any event no later than ten (10) days after the final determination of the Final Company EBITDA pursuant to Section 3(a). For the avoidance of doubt, neither EPOF nor OPPS shall be obligated to pay the Premium until the shareholders of the Company have approved a resolution authorizing the Capital Increase. Each of EPOF and OPPS shall vote in favor of the resolution authorizing the Capital Increase.

5

6. Prepayment. At any time prior to the calculation of the Final Company EBITDA, if the Company and OCM agree on the value of the Premium for the purposes of prepayment, the Capital Increase shall be carried out as soon as possible and neither EPOF nor OPPS shall have any obligation pursuant to Section 3 or Section 5 to pay any additional amount as Premium.
