THIRD: CALL OPTION II


3.1 The Buyer (and/or any of its Affiliates) may exercise Call Option II on the Shares Subject to Option II by giving the Sellers Notice of Exercise of the Call Option.


3.2 Given by the Buyer (and/or any of its Affiliates) the Notice of Exercise of the Call Option within a period not greater than ten (10) Business Days from the date of receipt of the last of the notices: (i) the Parties shall complete the purchase and sale of the Shares Subject to Option II; (ii) the Sellers shall transfer the Shares Subject to Option II to the Buyer (and/or its Affiliates); and (iii) the Buyer (and/or its Affiliates) shall pay or cause to be paid to the Sellers the Purchase Price II and shall perform the other acts provided in Clause Fifth (the “Closing”).

Likewise, the Parties agree that in the event that the Closing of Proyecto Harvest does not occur as of March 31, 2019, any type of advances that may have been received in such respect shall be discounted from the Purchase Price of Option I.


4.3. Without prejudice to the proportions of payment of Purchase Price II set forth in 4.2 (i) and (ii), the Buyer (and/or any of its Affiliates) shall have the power, at its discretion, to alter such proportions by cancelling Purchase Price II by delivery to the Sellers of greater or lesser quantity of cash and/or UAC Shares. Notwithstanding the foregoing, in all cases, the Buyer (and/or any of its Affiliates) shall make payments in cash or in kind, as the case may be, on a pro rata basis among the Sellers in accordance with their shareholdings and communicate such circumstance in the Notice of Exercise of the Call Option.


4.4 If Buyer (and/or any of its Affiliates) elects to pay Sellers the Purchase Price II by payment in kind of an amount greater than the equivalent of USD 34,995,000 (thirty-four million nine hundred and ninety-five thousand U.S. Dollars, ) in UAC Shares, then the Sellers will have an irrevocable put option whereby the Sellers will have the right to sell and the Buyer (and/or any of its Affiliates) will be obligated to purchase from the Sellers the quantity of UAC Shares delivered in excess of the Purchase Price II set forth in Clause 4.2(ii), all on the terms of Appendix 4.4 hereof. Shares Subject to the Irrevocable Put Option under the terms of Appendix 4.4 shall be exempt from any transfer limitation and from the exercise of the Option as well as from the pledge agreed in Appendix 4.6.

4.6 The particular provisions described in Appendix 4.6 hereof in relation to the payment of Purchase Price II under Purchase Option II shall apply to PMM and MMM.

Appendix 4.6 
Particular Provisions Applicable to PMM and MMMM


PMM and MMM state that on 10% of the MMM Shares Subject to Option II and the PMM Shares Subject to Option II there is an interim measure ordered in the case entitled “Harnan Miguel, Marcos y Martina c/Mac Mullen Jorge y otros s/ Medidas cautelares”, Case N° 76.745 filed at the Civil and Commercial Court No. 2 of San Nicolás, Buenos Aires Province (the “Interim Measure”), under which an embargo was placed on 44% of RASA’s share capital. The Interim Measure also placed an embargo on 30% of the dividends accruing from the liened RASA shares. Likewise, the MMM Shares Subject to Option II and the PMM Shares Subject to Option II could be affected by a nullity lawsuit in which the ownership of 80% of RASA’s share capital is argued in the proceedings “Harnan, Miguel, Marcos y Martina c/ Mac Mullen Jorge Enrique y otros s/ Acción de nulidad”, Case No. 76806, filed before the Civil and Commercial Court No. 5 of San Nicolás, Buenos Aires Province (the “Nullity Lawsuit”).


Accordingly, in the event of an unfavorable outcome (the procedural principles set out in the following paragraph apply) of the Interim Measure and/or the Nullity Lawsuit, PMM and MMM undertake to return to the Buyer and/or its Affiliates 75% of the UAC Shares received in payment in the event of the exercise of Call Option II, excluding shares received in excess of such calculation and which are subject to the irrevocable put option set forth in clause 4.4. As security for the fulfilment of their obligation, they undertake to pledge on the Closing Date such UAC Shares in substantially the same manner as the terms set out in Appendix 5.2 (v) in favor of the Buyer and/or its Affiliates.


The pledge on the UAC Shares will expire once the judicial proceedings listed above obtain a favorable result that completely rejects the claim of the plaintiff (in accordance with the modes of termination of the proceedings regulated in the Code of Civil and Commercial Procedure of the Province of Buenos Aires, including the transaction validated by final judgment) and are completed and, as long as there is no pending resolution or compliance with any claim, action or procedure directly or indirectly related to such legal proceedings, or which in any way could affect the peaceful ownership of and/or the exercise of the rights derived from the MMM Shares Subject to Option II and the PMM Shares Subject to Option II. It shall be understood that the conditions for the cancellation of the pledge have been met when: (i) the aforementioned conditions are met, (ii) the one-year limitation period for the autonomous action for review of the res judicata has elapsed (article 2564 Civil and Commercial Code), from the date on which the final judgement or decision on the merits which terminates the last of the legal proceedings referred to above becomes final (in accordance with the modes of termination of the proceedings regulated in the Civil and Commercial Procedural Code of the Province of Buenos Aires), and (iii) the termination of such proceedings has been notified in a reliable manner to the Buyer and/or its Affiliates.


15










PMM and MMM undertake to sustain and/or continue with the defense presented to date in the judicial proceedings mentioned above and not to perform any act that may affect the acquisition of MMM Shares Subject to Option II and PMM Shares Subject to Option II by the Buyer and/or its Affiliates.
