Re: Exclusivity
Letter
Dear Mr. Bosch:
Reference is made to that certain letter dated February
14, 2025 (the “Letter of Intent”) from Tether Investments, S.A. de C.V. (“Tether”) and addressed
to the board of directors of Adecoagro S.A. (the “Company”), with respect to a proposed transaction that would involve
the acquisition by Tether of such number of common shares, par value $1.50 per share (“Common Shares”), of the Company,
that would result in Tether and its affiliates collectively holding 51% of the outstanding Common Shares of the Company (the “Proposed
Transaction”). This letter (this “Exclusivity Letter”) is the exclusivity agreement referred to in the Letter
of Intent. For the avoidance of doubt, the Company and the Company’s board of directors have not agreed to the terms of the Proposed
Transaction, which remain subject to ongoing negotiation. All capitalized terms used and not otherwise defined in this Exclusivity Letter
shall have the meanings assigned to such terms in the Letter of Intent.
In consideration of Tether’s submission
of the Letter of Intent, evaluation of the Proposed Transaction and incurring expenses in connection therewith, the Company hereby agrees
that, for the period beginning on the date of this Exclusivity Letter and ending on the Expiration Date (as defined below) (the “Exclusivity
Period”), the Company shall not, and shall not authorize or permit any of its Representatives (as defined below) to, directly
or indirectly: (i) solicit, initiate, knowingly encourage, facilitate, discuss or negotiate any expression of interest, inquiry,
proposal, or offer from any Third Party (as defined below) relating to or that could reasonably lead to a possible Alternative Transaction
(as defined below); (ii) initiate, continue or otherwise participate in any discussions or negotiations or enter into any agreement
with, or provide any confidential, proprietary, or non-public information or data room access to, any Third Party relating to or in connection
with a possible Alternative Transaction; (iii) authorize, engage in, or enter into any agreement or understanding with respect to,
any Alternative Transaction, or (iv) accept any proposal or offer from any Third Party relating to a possible Alternative Transaction.
If, during the Exclusivity Period,
the Company or any of its Representatives receives from a Third Party any written expression of interest, proposal or offer regarding
or relating to an actual or possible Alternative Transaction, the Company will, to the extent legally permissible, promptly (and in any
event within 48 hours) notify Tether in writing that such expression of interest, proposal or offer has been received, and disclose to
Tether the material terms thereof (other than the identity of the Third Party making such written expression of interest, proposal or
offer).
Tether represents and warrants that as of the
date hereof, neither Tether nor any of its affiliates beneficially owns any securities of Company except for 20,398,699 Common Shares.
In consideration of the Company’s entering into this Exclusivity Letter, Tether agrees that, during the Exclusivity Period, except
in connection with an offer by Tether to acquire all of the Common Shares of Company not owned by Tether as of the date hereof, Tether
will not (and will ensure that its affiliates and associates (as such terms are defined in Rule 12b-2 of the Securities Exchange
Act of 1934, as amended (the “Exchange Act”)) and any person acting on behalf of or in concert with Tether or any
of its affiliates or associates will not), directly or indirectly, without the prior written consent of Company, (i) acquire, agree
to acquire, propose, seek or offer to acquire, or facilitate the acquisition or ownership of, any securities (whether debt or equity)
or assets of Company or any of its subsidiaries, or any warrant, option or other direct or indirect right to acquire any such securities
or assets, (ii) enter, agree to enter, propose, seek or offer to enter into or facilitate any merger, business combination, recapitalization,
restructuring or other extraordinary transaction involving Company or any of its subsidiaries, (iii) initiate, encourage, make,
or in any way participate or engage in, any “solicitation” of “proxies” as such terms are used in the proxy rules of
the U.S. Securities and Exchange Commission (the “SEC”) to vote, or seek to advise or influence any person with respect
to the voting of, any voting securities of Company (including, for the avoidance of doubt, indirectly by means of communication with
the press or the media), (iv) file with the SEC a proxy statement or any supplement thereof or any other soliciting material in
respect of Company or its shareholders that would be required to be filed with the SEC pursuant to Rule 14a-12 or other provisions
of the Exchange Act, (v) nominate or recommend for nomination a person for election at any shareholder meeting at which directors
of Company’s board of directors are to be elected, (vi) submit any shareholder proposal for consideration at, or bring any
other business before, any Company shareholder meeting, (vii) initiate, encourage, make, or in any way participate or engage in,
any “withhold” or similar campaign with respect to any Company shareholder meeting, (viii) form, join or in any way
participate in a “group” (within the meaning of Section 13(d)(3) of the Exchange Act) with respect to any voting
securities of the Company, (ix) call, request the calling of, or otherwise seek or assist in the calling of a special meeting of
the shareholders of Company, (x) otherwise act, alone or in concert with others, to seek to control or influence the management
or the policies of Company, (xi) disclose any intention, plan or arrangement prohibited by, or inconsistent with, the foregoing
or (xii) advise, assist or encourage or enter into any discussions, negotiations, agreements or arrangements with any other Persons
in connection with the foregoing; provided that the foregoing shall not prevent Tether from submitting confidential proposals to Company
with respect to the Proposed Transaction until such time as the Company notifies Tether that it is terminating discussions with Tether
concerning the Proposed Transaction. Tether’s obligations under this paragraph shall terminate immediately (and without further
action by any party hereto) if any Person or group of Persons shall have acquired or entered into a definitive agreement with Company
to acquire, or the board of directors of Company has approved, an acquisition of, more than 50% of each class of equity securities of
Company, or assets of Company or its subsidiaries representing more than 50% of the consolidated earning power of Company and its subsidiaries.
Tether further agrees that during the Exclusivity Period Tether will not (and will ensure that Tether’s affiliates and associates
(and any Person acting on behalf of or in concert with Tether or any of its affiliates or associates) will not), directly or indirectly,
without the prior written consent of Company take any action that would reasonably be expected to require Company to make a public announcement
regarding the possibility of a business combination, merger or other type of transaction described in this paragraph with Tether or any
of its affiliates.
In consideration of the Company’s entering
into this Exclusivity Letter, Tether further agrees that it will not, and will not cause any direct or indirect affiliate to, without
the consent of the Company, which consent shall not be unreasonably withheld, for a period of three months following the date hereof
(the “Lock-Up Period”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase
any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or
indirectly, any Common Shares or any securities convertible into or exercisable or exchangeable for Common Shares (including without
limitation, Common Shares or such other securities which may be deemed to be beneficially owned by Tether in accordance with the rules and
regulations of the SEC and securities which may be issued upon exercise of a stock option or warrant) (collectively with the Common Shares,
the “Lock-Up Securities”), (2) enter into any hedging, swap or other agreement or transaction that transfers,
in whole or in part, any of the economic consequences of ownership of the Lock-Up Securities, whether any such transaction described
in clause (1) or (2) above is to be settled by delivery of Lock-Up Securities, in cash or otherwise, or (3) publicly disclose
the intention to do any of the foregoing. Notwithstanding the foregoing, during the Lock-Up Period, Tether may transfer Lock-Up Securities
pursuant to a bona fide Third Party tender offer, merger, consolidation or other similar transaction made to all holders of the Company’s
capital stock, involving a change of control of the Company, provided that in the event that such tender offer, merger, consolidation
or other such transaction is not completed, the Lock-Up Securities shall remain subject to the restrictions of this paragraph. Tether
acknowledges and agrees that the foregoing precludes Tether from engaging in any hedging or other transactions or arrangements (including,
without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof, forward,
swap or any other derivative transaction or instrument, however described or defined) designed or intended, or which could reasonably
be expected to lead to or result in, a sale or disposition or transfer (whether by Tether or any other person) of any economic consequences
of ownership, in whole or in part, directly or indirectly, of any Lock-Up Securities, whether any such transaction or arrangement (or
instrument provided for thereunder) would be settled by delivery of Lock-Up Securities, in cash or otherwise.
Each of the parties acknowledges and agrees that,
in addition to all other remedies available (at law or otherwise), each party shall be entitled to seek equitable relief (including injunction
and specific performance) as a remedy for any breach or threatened breach of any provision of this Exclusivity Letter by the other party.

submissions filed, testimony rendered or arguments made, orders or awards issued or results of any proceedings conducted hereunder without
the prior written consent of both parties.

between the parties with respect to the subject matter hereof and supersedes all other prior agreements and understandings, both written
