Re: Contingent Share Purchase Transaction

Ladies and Gentlemen:

This master confirmation (this “Master Confirmation”), dated as of June 6, 2023 is intended to set forth certain terms and provisions of certain Transactions (each, a “Transaction”) that may be entered into from time to time between <<<Dealer Name>>> and Andean LFMA Investment Limited (“Counterparty”). This Master Confirmation, taken alone, is neither a commitment by either party to enter into any Transaction nor evidence of a Transaction. The additional terms of any particular Transaction shall be set forth in a Supplemental Confirmation substantially in the form of Annex A hereto (a “Supplemental Confirmation”), which shall reference this Master Confirmation and supplement, form a part of, and be subject to this Master Confirmation. This Master Confirmation and each Supplemental Confirmation together shall constitute a “Confirmation” as referred to in the Agreement specified below.

The definitions and provisions contained in the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”), as published by the International Swaps and Derivatives Association, Inc., are incorporated into this Master Confirmation. This Master Confirmation and each Supplemental Confirmation evidence a complete binding agreement between Counterparty and <<<Dealer Name>>> as to the subject matter and terms of each Transaction to which this Master Confirmation and such Supplemental Confirmation relate and shall supersede all prior or contemporaneous written or oral communications with respect thereto.

This Master Confirmation and a Supplemental Confirmation evidence a complete binding agreement between <<<Dealer Name>>> and Counterparty as to the terms of the Transaction to which this Master Confirmation and such Supplemental Confirmation relate. This Master Confirmation and each Supplemental Confirmation form a part of, and are subject to an agreement in the form of the ISDA 2002 Master Agreement, as published by ISDA, as if <<<Dealer Name>>> and Counterparty had executed that agreement on the date hereof (without any Schedule but with the modifications and elections set forth herein, the “Agreement”). All provisions contained in the Agreement govern this Master Confirmation and each Supplemental Confirmation except as expressly modified herein or in the related Supplemental Confirmation.

The Transactions shall be the sole transactions under the Agreement. If there exists any ISDA Master Agreement between <<<Dealer Name>>> and Counterparty or any confirmation or other agreement between <<<Dealer Name>>> and Counterparty pursuant to which an ISDA Master Agreement is deemed to exist between <<<Dealer Name>>> and Counterparty, then notwithstanding anything to the contrary in such ISDA Master Agreement, such confirmation or agreement or any other agreement to which <<<Dealer Name>>> and Counterparty are parties, the Transactions shall not be considered Transactions under, or otherwise governed by, such existing or deemed ISDA Master Agreement.

All provisions contained or incorporated by reference in the Agreement shall govern this Master Confirmation and each Supplemental Confirmation except as expressly modified herein or in such Supplemental Confirmation.

THIS MASTER CONFIRMATION, EACH SUPPLEMENTAL CONFIRMATION AND THE AGREEMENT WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO CHOICE OF LAW DOCTRINE. THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE UNITED STATES COURT FOR THE SOUTHERN DISTRICT OF NEW YORK IN CONNECTION WITH ALL MATTERS RELATING HERETO AND THERETO OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY AND WAIVE ANY OBJECTION TO THE LAYING OF VENUE IN, AND ANY CLAIM OF INCONVENIENT FORUM WITH RESPECT TO, THESE COURTS. NOTHING IN THIS PROVISION SHALL PROHIBIT EITHER PARTY FROM BRINGING AN ACTION TO ENFORCE A MONEY JUDGMENT IN ANY OTHER JURISDICTION.

If, in relation to any Transaction to which this Master Confirmation and a Supplemental Confirmation relate, there is any inconsistency between the Agreement, this Master Confirmation, such Supplemental Confirmation and the Equity Definitions, the following will prevail for purposes of such Transaction in the order of precedence indicated: (i) such Supplemental Confirmation; (ii) this Master Confirmation; (iii) the Equity Definitions; and (iv) the Agreement.

The foregoing shall not (i) limit the rights of <<<Dealer Name>>> to propose such adjustment or effect such termination at any time or (ii) obligate <<<Dealer Name>>> to delay, or continue delaying, proposing such adjustment or effecting such termination at any time (in each case, whether in <<<Dealer Name>>>’s capacity as Calculation Agent or Determining Party).

In addition, Counterparty acknowledges that the proprietary trading and other activities and transactions of <<<Dealer Name>>>, its affiliates or any entity with which <<<Dealer Name>>> hedges any Transaction hereunder, including purchases and sales of the Shares or Underlying Shares in connection with, or in anticipation of, such Transaction, may affect the trading price of the Shares or Underlying Shares.

(h) For the avoidance of doubt, and without limiting any representation contained in Section 3(a)(iii) of the Agreement, Counterparty represents that the execution, delivery and performance of this Master Confirmation, each Supplemental Confirmation and any other documentation relating to the Agreement to which Counterparty or any of its Affiliates is a party do not violate or conflict with any of the terms or provisions of any stockholders’ agreement, investment agreement, lock-up agreement, standstill agreement, registration rights agreement, confidentiality agreement or other agreement binding on Counterparty or its Affiliates or affecting Counterparty, its Affiliates or any of their respective assets (including its Shares or Underlying Shares).

In making any adjustment following any Potential Adjustment Event, the Calculation Agent shall take into account (among other factors) any adjustment made by the Depository under the Deposit Agreement, any fees and/or expenses of the Depositary and any taxes in connection therewith. If the Calculation Agent determines that no adjustment that it could make will produce a commercially reasonable result, it shall notify the parties that the relevant consequence shall be the termination of the relevant Transaction, in which case “Cancellation and Payment” will be deemed to apply and any payment to be made by one party to the other shall be calculated in accordance with Section 12.7 of the Equity Definitions.

(C) The definitions of “Merger Event”, “Tender Offer”, “Share-for-Share”, “Share-for-Other”, “Share-for-Combined”, “New Shares” and “Other Consideration” in Section 12.1 of the Equity Definitions shall be amended in accordance with the DS Amendment.

(D) The consequence of a Merger Event or Tender Offer in respect of the Shares shall be the relevant consequence specified in the Master Confirmation for such Merger Event or Tender Offer.

(E) Following the declaration by the Underlying Shares Issuer of the terms of any Merger Event or Tender Offer in relation to the Underlying Shares, the relevant consequence specified in the Master Confirmation for such Merger Event or Tender Offer shall apply, provided that if “Calculation Agent Adjustment” or “Modified Calculation Agent Adjustment” is specified as the relevant consequence in the Master Confirmation, then in each case where the Calculation Agent makes an adjustment to the Transaction the Calculation Agent shall take into account (among other factors) any adjustment made by the Depository under the Deposit Agreement, any fees and/or expenses of the Depositary and any taxes in connection therewith.

(F) The definitions of “Nationalization” and “Insolvency” in Section 12.6 of the Equity Definitions shall be amended in accordance with the DS Amendment.

(G) The consequence of a Nationalization or Insolvency in respect of the Underlying Shares or the Underlying Shares Issuer shall be the relevant consequence specified in this Master Confirmation.

(H) Notwithstanding anything to the contrary in the Master Confirmation, the consequence of a Nationalization or Insolvency in respect of the Shares or the Depository shall be Cancellation and Payment, provided that the parties may agree that a replacement of the Shares with Replacement DSs should take place and that one or more terms of the Transaction should be amended and if the parties so agree, then Cancellation and Payment shall not apply in respect of such Nationalization or Insolvency, as applicable, and references to Shares herein shall be replaced by references to such Replacement DSs and any agreed amendments will be made, in each case with effect from the date agreed by the parties.

(I) If a Delisting of the Shares occurs or the Depository announces that the Deposit Agreement is (or will be) terminated, then:

(1) notwithstanding anything to the contrary in the Master Confirmation, Cancellation and Payment will apply as provided in this Master Confirmation; provided that the parties may agree that a replacement of the Shares with Replacement DSs or the Underlying Shares should take place and that one or more terms of the Transaction should be amended, and if the parties so agree, then Cancellation and Payment shall not apply in respect of such Delisting or termination of the Deposit Agreement, as applicable, and references to Shares herein shall be replaced by references to such Replacement DSs or the Underlying Shares, as applicable, and any agreed amendments will be made, in each case with effect from the date agreed by the parties; and

22

(2) where Cancellation and Payment applies under clause (I)(1) above in respect of a termination of the Deposit Agreement, the Equity Definitions shall be interpreted as follows: (i) such termination shall be deemed to be an “Extraordinary Event”; (ii) Cancellation and Payment shall apply as defined in Section 12.6(c)(ii) of the Equity Definitions; and (iii) the definition of “Announcement Date” in Section 12.1(l) of the Equity Definitions shall include the following additional clause (vii) at the end of the first sentence thereof: “(vii) in the case of a termination of the Deposit Agreement, the date of the first public announcement by the Depository that the Deposit Agreement is (or will be) terminated”.

(J) The definition of “Insolvency Filing” in Section 12.9(a)(iv) of the Equity Definitions, shall each be amended in accordance with the DS Amendment.

(K) For the avoidance of doubt, where a provision is amended by this Section 11 in accordance with the DS Amendment, if the event described in such provision occurs in respect of the Underlying Shares or the Underlying Shares Issuer, then the consequence of such event shall be interpreted consistently with the DS Amendment and such event.

12. Foreign Private Issuer Status: Counterparty will provide a written notice to <<<Dealer Name>>> promptly upon becoming aware that the Underlying Shares Issuer is not or will no longer be a “foreign private issuer”, as defined in Rule 3b-4 of the Exchange Act.
