The undersigned, ● (the “Holder”), understands that the Company and Gold Fields Limited (the “Acquiror”) propose to enter into an arrangement agreement dated as of the date hereof (the “Arrangement Agreement”) contemplating the acquisition by the Acquiror, indirectly through a subsidiary of the Acquiror, of all of the issued and outstanding common shares of the Company (“Yamana Shares”) pursuant to a plan of arrangement under the provisions of the Canada Business Corporations Act.

Capitalized terms used in this letter agreement not otherwise defined herein shall have the respective meanings given to them in the Arrangement Agreement.

The Holder is the beneficial owner of, or exercises control or direction over, the number of Gold Fields Shares (the “Holder Shares”), Gold Fields ADSs (the “Holder ADSs”), Gold Fields Performance Shares (the “Holder Performance Shares”), Gold Fields Matching Shares (the “Holder Matching Shares”), Gold Fields Retention Shares (the “Holder Retention Shares”) and Gold Fields Restricted Shares (the “Holder Restricted Shares”), as applicable, set out in Appendix A hereto. The Holder Shares, Holder ADSs, Holder Performance Shares, Holder Matching Shares, Holder Retention Shares and Holder Restricted Shares, together with any other securities of the Acquiror directly or indirectly acquired by or issued to the Holder during the term of this letter agreement, are collectively referred to herein as the “Holder Securities”.

REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF THE HOLDER

The Holder hereby covenants and agrees, in his/her/its capacity as securityholder and not in any capacity as an officer or director of the Acquiror, from the date hereof until the termination of this letter agreement:

The Holder hereby represents and warrants to the Company, and acknowledges that the Company is relying on such representations and warranties in connection with entering into this letter agreement and the Arrangement Agreement, that: (a) the Holder has the legal capacity to enter into and perform his/her obligations under this letter agreement; (b) the Holder is, and on the record date of the Gold Fields Meeting will be, the beneficial owner of, or exercise control or direction over, the Holder Securities, with good title thereto free and clear of any and all Liens; (c) the Holder has the sole and exclusive right to vote (if applicable) and sell all of the Holder Securities, and, other than pursuant to this letter agreement, none of the Holder Securities is subject to any proxy, power of attorney, attorney-in-fact, voting trust, vote pooling or other agreement with respect to the right to vote, call meetings of shareholders or give consents or approvals of any kind; (d) except for the Arrangement Agreement, no Person has any agreement or option, or any right or privilege (whether by law, pre-emptive or contractual) capable of becoming an agreement or option for the purchase, acquisition or transfer from the Holder of any of the Holder Securities or any interest therein or right thereto; (e) the only securities of the Acquiror beneficially owned by the Holder and/or over which the Holder exercises control, directly or indirectly, on the date hereof are the Holder Securities set forth in Appendix A hereto; (f) this letter agreement has been duly executed and delivered by the Holder and is a valid and binding agreement, enforceable against the Holder in accordance with its terms, subject to bankruptcy, insolvency and other similar Laws affecting creditor rights generally and to principles of equity; and (g) the execution and delivery by the Holder of this letter agreement and the performance by the Holder of his/her/its obligations hereunder do not constitute a violation or breach of or default under, or conflict with, any contract, commitment, agreement, understanding or arrangement of any kind to which the Holder is or will be a party and by which the Holder is or will be bound at the time of such performance. The representations and warranties of the Holder set forth in this paragraph shall not survive the completion of the Arrangement and will expire and be terminated on the earlier of the Effective Time and the date on which this letter agreement is terminated in accordance with its terms.

The Holder acknowledges that he/she/it (a) has read this letter agreement in its entirety, understands it and agrees to be bound by its terms and conditions, (b) has been granted the opportunity to ask questions of, and to receive answers from, the Acquiror’s legal counsel concerning the terms and conditions of this letter agreement, (c) has been advised to seek independent legal advice with respect to the execution and delivery of this letter agreement and has received such advice or has, without undue influence, elected to waive the benefit of any such advice, and (d) is entering into this letter agreement voluntarily.

REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF THE COMPANY

The Company hereby represents and warrants to the Holder, and acknowledges that the Holder is relying on such representations and warranties in connection with entering into this letter agreement, that: (a) the Company is validly existing under the federal laws of Canada and has all necessary corporate power and capacity to execute and deliver this letter agreement and to perform its obligations hereunder, and the execution and delivery of this letter agreement by the Company and the consummation of the transactions contemplated hereby have been duly authorized by all necessary corporate action on the part of the Company; (b) this letter agreement has been duly executed and delivered by the Company and is a valid and binding agreement, enforceable against the Company in accordance with its terms, subject to bankruptcy, insolvency and other similar Laws affecting creditor rights generally and to principles of equity; and (c) the execution and delivery by the Company of this letter agreement and the performance by the Company of its obligations hereunder will not constitute a violation or breach of or default under, or conflict with, any constating documents of the Company or any contract, commitment, agreement, understanding or arrangement of any kind to which the Company is or will be a party and by which the Company is or will be bound at the time of such performance. The representations and warranties of the Company set forth in this paragraph shall not survive the completion of the Arrangement and will expire and be terminated on the earlier of the Effective Time and the date on which this letter agreement is terminated in accordance with its terms.

Notwithstanding any other provision of this letter agreement, the Company hereby agrees and acknowledges that the Holder is bound hereunder solely in its capacity as a securityholder of the Acquiror and that the provisions hereof shall not be deemed or interpreted to bind the Holder in his/her capacity as a director, officer or employee of the Acquiror (if the Holder holds such office). Without limiting the foregoing, the Company acknowledges and agrees that: (a) action taken by the Holder in his/her capacity as a director, officer or employee of the Acquiror shall not be a violation of this letter agreement; and (b) nothing in this letter agreement shall prevent the Holder from serving as, or fulfilling his/her fiduciary duties as, a director or officer of the Acquiror.

GENERAL

The parties agree that the details of this letter agreement may be described in any press release, material change report, information circular or other disclosure document or communication prepared by the Acquiror or the Company in connection with the Arrangement and further agree to this letter agreement being made publicly available, including by filing on SEDAR and EDGAR and by any filings made under the securities laws of Canada, the United States, or any state thereof, and South Africa (including disclosure of each party’s identity, ownership of Holder Securities and the nature of the parties’ commitments, arrangements and understandings under this letter agreement and any other information required by applicable Laws), in accordance with applicable Laws.

This letter agreement shall automatically terminate and be of no further force or effect only upon the earliest of (a) the written agreement of the Holder and the Company, (b) the termination of the Arrangement Agreement in accordance with its terms, and (c) the Effective Time. This letter agreement may also be terminated by the Holder upon written notice to the Company (a) if the terms of the Arrangement Agreement are varied in a manner that is materially adverse to the Holder without the Holder’s consent or (b) in the event of a Gold Fields Change in Recommendation. If this letter agreement is terminated in accordance with its terms, this letter agreement shall become void and be of no further force or effect and the Holder shall be entitled to withdraw any form of proxy or power of attorney which it may have given with respect of the Holder Securities, without liability of either party; provided that the foregoing shall not relieve either party from any liability for any wilful, intentional or fraudulent breach of its respective obligations under this Agreement arising prior to such termination.

This letter agreement shall be governed by the laws of the Province of Ontario and the federal laws of Canada applicable therein.

The parties agree to pay their own respective costs and expenses incurred in connection with this letter agreement and all documents and instruments executed or prepared hereto.

This letter agreement shall be binding upon the Company and the Holder and upon their respective heirs, legal representatives, successors and permitted assigns (as applicable), provided that neither the Company nor the Holder may assign, delegate or otherwise transfer any of its respective rights, interests or obligations under this letter agreement without the prior written consent of the other, except that the Company may assign, delegate or otherwise transfer any of its rights, interests or obligations under this letter to an affiliate, without reducing the Company’s obligations hereunder. Any provision of this letter agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed, in the case of an amendment, by each of the parties, and in the case of a waiver, by the party against whom the waiver is to be effective, and no failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise.

The parties acknowledge and agree that irreparable damage may occur in the event any of the provisions of this letter agreement are not performed in accordance with their specific terms or otherwise are breached or violated. Accordingly, the parties agree that, without posting bond or other undertaking, the parties will be entitled to an injunction or injunctions to prevent breaches or violations of the provisions of this letter agreement and to enforce by specific performance this letter agreement and the terms and provisions hereof in any claim (whether at law or in equity, whether civil or criminal), cause of action (whether in contract, tort or otherwise), hearing, charge, complaint, demand or notice to, from, by or before any Governmental Entity having jurisdiction over the parties and the matter, in addition to any other remedy to which a party may be entitled, at law or in equity, and the parties hereby waive any and all defences which could exist in their favour in connection with such enforcement and waive any requirement for security or the posting of any bond in connection with such enforcement.

If any term or other provision of this letter agreement is invalid, illegal or incapable of being enforced by any rule or Law or public policy, that provision will be severed from this letter agreement and all other conditions and provisions of this letter agreement shall nevertheless remain in full force and effect.

This letter agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements and understandings between the parties with respect thereto.

This letter agreement may be executed in any number of counterparts (including counterparts by facsimile or electronic mail) and all such counterparts taken together shall be deemed to constitute one and the same instrument. The parties shall be entitled to rely upon delivery of an executed facsimile or similar executed electronic copy of this letter agreement, and such facsimile or similar executed electronic copy shall be legally effective to create a valid and binding agreement between the parties.
