MANAGEMENT SERVICES AGREEMENT

THIS MANAGEMENT SERVICES AGREEMENT (this “Agreement”) is made as of July 1, 2007, by and between Golden Star Resources Ltd., a company incorporated under the laws of Canada (the “Company”) and Golden Star Management Services Company, a Delaware corporation (the “Manager”). The Company and the Manager are each referred to herein as a “Party” and jointly as the “Parties.”

WHEREAS, the Company requires assistance with respect to its management, administration and business operations;

WHEREAS, the Manager maintains a staff of highly skilled and experienced industry personnel;

WHEREAS, the Company wishes to engage the Manager to provide certain administrative and management services to the Company, and the Manager wishes to provide such services to the Company as set forth in this Agreement;

NOW, THEREFORE, in consideration of the promises set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, intending to be legally bound, agree as follows:

1. Services.

(a) The Company hereby engages the Manager and the Manager hereby agrees that it shall provide the services described in Schedule I of this Agreement (which includes services that Manager will provide without any applicable markup) and Schedule II of this Agreement (which includes services that Manager will provide with an applicable markup) (collectively, the “Services”).

(b) In addition, Manager will from time to time pay certain costs (“Additional Costs”, as defined in Section 3(a) and examples of which are included in Schedule III of this Agreement) on behalf of Company without any applicable markup.

(c) The Parties intend that the services identified on Schedule I will be those Services that are eligible for the “services cost method”, as such term is used in Treasury Regulation § 1.482-9T (and any successor regulation), and that Services that are ineligible for such method will be identified on Schedule II; and, the Parties agree to amend Schedules I and II when and as appropriate to achieve this result. In addition, the Parties may, at any time and by mutual agreement, add a service, delete a service, or modify a service to be performed pursuant to this Agreement. The Manager may retain unaffiliated consultants or subcontractors to carry out its obligations hereunder if the Manager, in its discretion, deems such consultants or subcontractors necessary, desirable or advisable.

2. Term. This Agreement will become effective as of July 1, 2007 (the “Effective Date”), and shall remain in full force and effect until terminated in accordance with Section 8.

3. Fees.

(a) In consideration of the Services to be rendered by the Manager pursuant to this Agreement, the Company shall pay the Manager and the Manager shall be entitled to receive a fee equal to the “Monthly Service Fee”, as defined in Section 3(f). In addition, the Manager shall be reimbursed by the Company for any amount that the Manager pays that (i) is paid by the Manager, in carrying out its duties as Manager, on behalf and for the benefit of the Company, and (ii) is not part of the Allocable Cost of a service, as such term is used in Section 3(e) (the “Additional Costs”). Examples of Additional Costs are included on Schedule III of this agreement.

(b) The Company may, at its sole option, provide Manager with an advance. Unless the Parties agree otherwise, any advance made pursuant to this Section 3(b) shall be considered an advance against payments due to the Manager described in Section 3(d), and shall be recouped from the next amounts otherwise payable under Section 3 (d).

(c) The Manager shall establish and maintain adequate accounting, management information and cost accounting systems that identify all accounting items related to the Services, Allocable Costs and Additional Costs. The Company or a mutually agreed upon certified public accountant (i) shall have access, at all reasonable times, to the accounts and records maintained by the Manager that relate to the performance of Services or the determination of Allocable Costs or Additional Costs and (ii) may inspect, copy and audit such accounts and records of the Manager that relate to the performance of Services and the determination of the Allocable Costs and Additional Costs.

(d) The Manager shall invoice the Company for the Monthly Service Fee, as defined in Section 3(f) as soon as practicable following the last day of each month and such invoiced amount shall be immediately due and payable by the Company. The Manager shall invoice the Company for the Additional Costs, if any, and such Additional Costs shall be payable by the Company monthly, in arrears.

(e) The “Allocable Cost” of providing a service shall include all costs directly identified with or reasonably allocated to the provision of a service, including, but not limited to, a reasonable portion of overhead and general and administrative charges.

(f) The “Monthly Service Fee” shall be the sum of (i) the Allocable Cost of providing the services on Schedule I, and (ii) 1.07 times the Allocable Cost of providing the services on Schedule II. The Monthly Service Fee shall accrue throughout the applicable calendar month. In computing the Monthly Service Fee pursuant to this Section 3(f), the Allocable Cost of providing a service for a month of determination shall be the Allocable Costs with respect to such service accrued by the Manager for such month.

6. Indemnification and Exculpation.

(a) Subject to Section 6(c) hereof, to the fullest extent permitted by law, the Company shall indemnify and save harmless the Manager, and its officers, directors or employees (each, an “Indemnified Party”) from and against any and all claims, liabilities, damages, losses, costs and expenses (including amounts paid in satisfaction of judgments, in compromises and settlements, as fines and penalties and reasonable attorneys’ fees and other legal or other costs and expenses of investigating or defending against any claim or alleged claim but excluding any liabilities for taxes of any Indemnified Party), known or unknown, liquidated or

4

unliquidated, that are incurred by such Indemnified Party and arise out of or in connection with the business of the Company or the performance by such Indemnified Party of its responsibilities hereunder (including, without limitation, those that arise out of or in connection with the employment by the Manager of advisors, agents or other third parties to assist the Manager in the performance of its duties pursuant to this Agreement) (each of the foregoing, a “Claim”); provided, that an Indemnified Party shall not be entitled to indemnification hereunder to the extent such Claim arises from willful misconduct, bad faith or conduct that is otherwise not in accordance with the standard of care set forth in Section 5(a). The termination of any proceeding by settlement, judgment, order or upon a plea of nolo contendre or its equivalent shall not, of itself, create a presumption that an Indemnified Party was engaged in willful misconduct or bad faith. Any person or entity entitled to indemnification from the Company hereunder shall obtain the written consent of the Company (which consent shall not be unreasonably withheld) prior to entering into any agreement or settlement that would result in an obligation of the Company to indemnify such person or entity.

(b) Expenses incurred by an Indemnified Party in defense or settlement of any Claim that may be subject to a right of indemnification hereunder may be advanced by the Company prior to the final disposition thereof upon receipt of an undertaking by or on behalf of the Indemnified Party to repay such amount to the extent that it shall be determined ultimately that such Indemnified Party is not entitled to be indemnified hereunder. The right of any Indemnified Party to the indemnification provided herein shall be cumulative of, and in addition to, any and all rights to which such Indemnified Party may otherwise be entitled by contract or as a matter of law or equity and shall be extended to such Indemnified Party’s successors, assigns and legal representatives.

(c) Promptly after receipt by an Indemnified Party of notice of the commencement of any action or proceeding or threatened action or proceeding in connection with any Claim referred to in Section 6(a), such Indemnified Party shall give written notice thereof to the Company; provided, that the failure of an Indemnified Party to give such notice shall not relieve the Company of its obligations pursuant to this Section 6, except to the extent that the Company is actually prejudiced by such failure to give notice.

(d) In case any action or proceeding is commenced against any Indemnified Party that may be subject to indemnification pursuant to this Section 6, the Company shall have the right to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Party. After notice from the Company to such Indemnified Party of the Company’s election to assume the defense thereof, the Company will be liable for the expenses subsequently incurred by such Indemnified Party in connection with the defense thereof. The Company will not consent to the entry of any judgment or enter into any settlement that does not include as an unconditional term the giving to such Indemnified Party a release from all liability in respect of such Claim.

7. No Partnership. Nothing contained herein shall create, or shall be construed as creating, a partnership or joint venture of any kind or as imposing upon any Party any partnership duty, obligation or liability to any other Party. Each Party shall be an independent contractor hereunder and neither shall be the agent of any other Party.

(B) At the request and expense of the Company upon the termination of this Agreement for any reason, the Manager shall exercise good faith and due diligence to assign to the Company all of the Manager’s rights to the extent assignable under subcontracts and other contractual agreements entered into by the Manager in connection with the performance of the Services as may be designated by the Company.
