(b) Your vested benefits in Employer’s qualified and non-qualified retirement plans will be paid to you in accordance with the terms of the applicable plan.

6. Release. With the exception of any claim that the law precludes you from waiving by agreement, you irrevocably and unconditionally release, acquit and forever discharge Releasees (as hereinafter defined) from any and all charges, complaints, claims, promises, agreements, controversies, liabilities, obligations, damages, actions, causes of action, suits, rights, demands, costs, losses, debts and expenses (including attorney’s fees and costs actually incurred), of any nature whatsoever, known, whether based on contract, statute or common law, or unknown which arise from any and all events occurring on or before the date of this Agreement and which arise or relate in any way to your employment by Employer, including without limitation, all claims arising from actions or inactions by any of the Releasees. To the extent applicable law may prohibit a waiver of claims under a particular statute, you acknowledge that you have no valid claim under the statute. You do not waive or release (i) any rights arising after the date of this Agreement; (ii) any obligations created by or arising out of this Agreement; (iii) your right to indemnification for all necessary expenditures or losses incurred by you in direct consequence of the discharge of your duties for Employer pursuant to applicable law or any relevant agreements or policies of Company; provided, however, that such right to indemnification shall be subject to all applicable limitations under applicable law and Employer’s constating documents and this Agreement shall not expand in any way your right to indemnification; or (iv) any claims that are related to your rights solely as a stockholder in Employer and arising after the date of this Agreement and where such rights as a stockholder are unrelated in any way to your prior employment by Employer or your actions as director of Employer. In consideration for the foregoing, the Company does hereby irrevocably and unconditionally release, acquit and forever discharge you, or your agents, representatives, heirs, or beneficiaries, from any and all claims, known or unknown, which the Company may have against you or your or your agents, representatives, heirs, or beneficiaries, and that arise in any way out of the Employment Agreement, your employment with Employer or serving as a member of Employer’s board of directors; provided, however, that for the avoidance of doubt, you acknowledge and agree that such release expressly excludes any claims involving willful and intentional misconduct or fraud.

(a) Additional Scope of Release. In addition, and not by way of limitation, to the broad and general release set forth above, you specifically acknowledge and agree that by executing this Agreement you are releasing any claims against Releasees for (i) disability discrimination in violation of the Americans with Disabilities Act of 1990 (“ADA”) (42 U.S.C. §§ 12101), (ii) any violation of the Civil Rights Act of 1964 (42 U.S.C. §§ 2000e, et. seq.)(“Title VII”), or the Equal Pay Act of 1963 (29 U.S.C. § 2006(d)), (iii) any claims under 42 U.S.C. Section 1981, (iv) claims under the Employee Retirement Income Security Act of 1974 (“ERISA”), (v) any claims under the Age Discrimination in Employment Act of 1967 (“ADEA”), the Older Workers Benefit Protection Act (“OWBPA”), the Family and Medical Leave Act (29 U.S.C. § 2601, et. seq.)(“FMLA”), the Worker Adjustment Retraining and Notification Act, Nevada Revised Statutes §§ 613.310 to 613.430 (Employment Discrimination, Harassment and Retaliation); Nevada Revised Statutes §§ 608.005 to 608.195 (Payment and Collection of Wages and Penalties); Nevada Revised Statutes §§ 618.005 to 618.936 (Nevada Occupational Safety and Health Act); Nevada Genetic Information and Testing Law; Nevada Labor Relations Laws; (vi) any claims under any state law, statute or ordinance, including state equal opportunities for

This release shall also include claims for interference with contract and/or prospective economic advantage and claims relating to or arising from any right to purchase, or actual purchase of equity or debt interests in Employer; provided, however, that this release shall expressly exclude any of your rights relating to Eligible PSUs and Eligible RSUs.

(b) Waiver of Unknown Claims. You and the Company expressly waive all rights under Section 17.245 of the Nevada Revised Statutes, understanding and acknowledging the significance of such specific waiver of Section 17.245, which reads as follows:

When a release or a covenant not to sue or not to enforce judgment is given in good faith to one of two or more persons liable in tort for the same injury … : (a) It does not discharge any of the other tortfeasors from liability for the injury … unless its terms so provide, but it reduces the claim against the others to the extent of any amount stipulated by the release or the covenant, or in the amount of the consideration paid for it, whichever is the greater[.]

This release includes, without limitation, all claims which you or the Company do not know or suspect to exist in your favor at the time you sign this Agreement.

(c) Affirmations. You affirm that you have reported all hours worked as of the date of this Agreement and have been paid, all compensation, including wages, overtime, bonuses, commissions, vacation pay, tips, penalties, fines, shares, stock options, and/or other benefits and compensation to which you may be entitled, other than the payments and benefits set forth in Sections 2(b) and 4 and the outstanding equity awards under Employer’s Restricted Share Plan set forth in Section 5 of this Agreement. You agree that the foregoing payment, along with any final wages paid to you, includes and exceeds all and other compensation due and payable to you through the Termination Date. You also affirm that you received all leave (paid or unpaid) to which you were entitled, and/or that you were not denied requested leave (paid or unpaid) to which you were entitled under the FMLA, the ADA, or any other applicable federal, state, or local leave statute or law. You further affirm that you have no known workplace injuries or occupational diseases for which you have not filed a claim for workers’ compensation benefits. Further, you affirm that all of Employer’s decisions regarding your pay and benefits through the Termination Date were not discriminatory based on age, disability, race, color, sex, religion, national origin, sexual orientation, Veteran status, or any other classification protected by law.

(d) Mistake of Fact. You and the Company expressly assume the risk of any mistake of fact in connection with the matters compromised herein or in regard to facts relating thereto which are now unknown. In this connection, you and the Company acknowledge and waive any provisions of law or statute which limit in any way the giving of a general release.

4

(e) Consideration. You recognize that the monies, benefits and treatment of equity awards set forth in this Agreement constitute consideration for this Release and you agree that you will not seek anything further from any Releasee; provided, however, that nothing herein shall prevent you from exercising your rights solely in your capacity as a stockholder of Employer for claims arising after the date of this Agreement and where such rights as a stockholder are unrelated in any way to your prior employment by Employer or your actions as director of Employer. You recognize that you are bound by this Agreement and that anyone who succeeds to your rights and responsibilities, such as your heirs or the executor of your estate, is also bound. This Agreement is made for the benefit of the Releasees, including the individuals and entities collectively described herein, as well as all who succeed to their rights and responsibilities, such as the successors and assigns of the corporate entities, and the heirs and executors of the estates of the individuals collectively referred to herein as Releasees.

(f) Definition of Releasee. As used in this Agreement, the term “Releasees” shall include the Company, including without limitation Employer, and each of the Company’s successors, assigns, heirs, agents, directors, board members, officers, employees, insurers, former employees, employee benefit plans and trusts, representatives, attorneys, parent or subsidiary entities, acquiring or acquired entities, related entities (and agents, directors, officers, employees, representatives and attorneys of such related entities), and all persons acting by, through, under or in concert with any of them.

7. No Claims and Covenant Not to Sue. You represent and warrant that you have not filed any complaints, claims, charges, appeals, or actions against Releasees with any state, federal, or local agency or court and that you will not do so at any time hereafter. Nothing in this Agreement shall be construed to prohibit you from filing a charge or complaint with the Equal Employment Opportunity Commission (EEOC), the National Labor Relations Board (NLRB), or any other federal, state or local agency charged with the enforcement of any employment laws, challenging the validity of this Agreement or participating in any investigation or proceeding conducted by such agency. With regard to the release of claims under the ADEA and the OWBPA, you may challenge the knowing and voluntary nature of this release as it extends to such age discrimination claims. However, you are hereby releasing and forever waiving any private right to sue and any claim for or right to receive damages, monies or other compensation that is granted or awarded by the EEOC, NLRB, or any other state, federal or local governmental or administrative agency.

8. Recitals; Legal Representation; and Voluntary Execution. You understand and agree that, you:

10. No Detriment or Disparagement.

(a) You shall not (i) engage or intentionally cause or direct others to engage in any act detrimental to any of the Company, any of their officers, partners, members, associates, employees, directors, managers, parents, subsidiaries, affiliates and related entities, and/or their business relations or (ii) make or intentionally cause or direct others to make any publication, oral, written or by implication, of a defamatory, disparaging or otherwise derogatory matter pertaining the Company, any of their officers, partners, members, associates, employees, directors, managers, parents, subsidiaries, affiliates and related entities, and/or their business relations or to your employment relationship with Employer or its subsidiaries and affiliates and/or their business relations.

(b) Except as otherwise required by law, the Company agrees that, as a company, it will refrain from any publication, oral and/or written, of a defamatory, disparaging or of an untruthful nature pertaining to you or your employment with Employer and will provide notice to its officers and directors of its obligations under this Section 10(b) to refrain from any publication, oral and/or written, of a defamatory, disparaging or of an untruthful nature pertaining to you or your employment with Employer; provided, however, that you acknowledge and agree that actions by individual employees of the Company in their private and individual capacity and not on behalf of Employer which are inconsistent with this Section 10(b) will not amount to a breach of this Section 10(b) by the Company.

(c) If a breach or threatened breach of any covenant contained in this Section 10 occurs, the nonbreaching party shall be entitled, in addition to any other remedy available in law, to injunctive relief in order to prevent the irreparable harm that may occur if such breach is allowed to occur or continue to occur.

11. Post-Employment Covenants. You understand, acknowledge, agree and confirm that, your Nondisclosure, Noncompetition, Nonsolicitation and Inventions Agreement with the Company, a copy of which is attached hereto as Exhibit A and is incorporated by reference herein, that such terms and those set forth in this Section 11 are reasonable and necessary to protect the Company’s rights and property, remains in full force and effect and sets forth your binding obligations and, in consideration for Employer’s execution of this Agreement and the offer of monies and other benefits to you hereunder, in addition to your obligations under your Nondisclosure, Noncompetition, Nonsolicitation and Inventions Agreement and without limiting such agreement in any way, you further expressly acknowledge and agree to comply with each of the following covenants:

(a) Restrictive Covenants. The covenants set forth in Sections 6, 7 and 9 of the Nondisclosure, Noncompetition, Nonsolicitation and Inventions Agreement set forth on Exhibit A are expressly incorporated by reference herein and made a part hereof. For the avoidance of doubt, the parties hereto acknowledge and agree that as of the date of this Agreement the Company is not engaging in the activities described in clauses (i) and (ii) of the second paragraph of Section 7 of the Nondisclosure, Noncompetition, Nonsolicitation and Inventions Agreement set forth on Exhibit A in mineral districts outside of the State of Nevada.

7

(b) Trade Secrets. You shall continue to keep secret and retain in the strictest confidence, and shall not disclose, publish, disseminate, or otherwise reveal or use, for your benefit or others, any of the Company’s trade secrets, defined as information which: (i) derives economic value, actual or potential, from not being generally known to the public or readily ascertainable by other persons (outside the Company) who can obtain economic value from its disclosure or use; and (ii) is the subject of efforts that are reasonable under the circumstances to maintain its secrecy or confidentiality.

(c) Non-Solicitation of Certain Supervised Employees. Notwithstanding anything to the contrary in the Nondisclosure, Noncompetition, Nonsolicitation and Inventions Agreement, for a period of two (2) years following the Termination Date, you will not recruit, hire, or attempt to recruit or hire, directly or by assisting others, any employee of the Company, who was employed by the Company at any time during the final six (6) months of your employment with Employer; provided, however, that nothing herein shall restrict general solicitations of employment (or the subsequent employment) not specifically directed towards employees of the Company.

(d) Cooperation in Legal Matters. You agree that upon reasonable notice from the Company, you will make yourself available to the Company, and cooperate honestly and accurately with the Company, in connection with any proceedings before any court or agency, pertaining to any matter with respect to which you have knowledge or information as a result of your employment with Employer, including its subsidiaries and affiliates. The Company agrees, upon receipt of proper documentation, to reimburse you for reasonable costs that you incur in fulfilling this covenant.

(e) Covenant Application and Remedies. You acknowledge that the covenants of this Agreement, including without limitation the covenants incorporated by reference herein, specifically including those set forth in this Section 11, are reasonably necessary to protect the goodwill, trade secrets and other business interests of Employer and that they will cause you no undue hardship. You acknowledge that any breach of these covenants will cause the Company immediate irreparable harm for which injunctive relief would be necessary. Without limiting other possible remedies to the Company for the breach of the covenants set forth in this Section 11, including without limitation the covenants incorporated by reference herein, you agree that injunctive or other equitable relief shall be available to enforce these covenants, such relief to be without the necessity of the Company posting a bond. In the event you breach any of the covenants set forth in Sections 11(a) – (c), including without limitation the covenants incorporated by reference herein, Employer’s obligations to make payments or extend rights pursuant to the provisions of Sections 4 and 5 hereof shall be of no further force and effect and shall immediately cease and, notwithstanding any other provision to the contrary in this Agreement or any of the Equity Award Agreements, you shall immediately forfeit any rights with respect to future vesting of unvested Eligible PSUs and Eligible RSUs, which awards will immediately be cancelled and forfeited. These Section 11 covenants shall be construed as independent of any other provision in this Agreement, and the existence of any claim or cause of action of yours against Employer, whether predicated on this Agreement or

8

otherwise, will not constitute a defense to the enforcement by the Company of these covenants. You further acknowledge that this Agreement does not diminish the effect of any other confidentiality covenants or agreements you previously may have made with the Company, including without limitation, Employer, and that the Company, including without limitation, the Employer, has the full right to enforce the provisions of all such covenants or agreements in addition to those contained in this Agreement.

12. Return of Property. Upon the Termination Date you shall promptly deliver to Employer all computers, computer equipment, credit cards, keys, manuals, notebooks and all confidential information and other data relating to the Company in your possession or custody or under your control belonging to or in any way relating to the business of the Company, or any of their respective customers and by your signature on this Agreement you hereby represent and warrant to the Company that all such property and information, including, without limitation, all files, records, documents, drawings, specifications, client lists, equipment, graphics, designs, and similar items, including any and all copies whether prepared by you or otherwise coming into your possession, shall remain the exclusive property of the Company and have not and will not be removed from the premises of the Company by you or your agent(s). You further represent and warrant that you have returned all such files, records, documents, drawings, specifications, client lists, equipment, graphics, designs, and similar items, including any and all copies whether prepared by you or otherwise coming into your possession and that no such documents, files, or information are within your possession or control.

13. No Admission of Liability. Neither this Agreement nor compliance with this Agreement constitutes an admission by the Company, including without limitation, Employer, that any action taken with respect to you was wrongful, unlawful or in violation of any order, law, statute, local, state, or federal act, statute, constitution, common law or contract, and the Company, including without limitation, Employer, specifically denies any such wrongdoing or violation. You shall not state or imply the contrary to any person or entity.

14. Withholding. All payments being made to you under this Agreement will be subject to withholding for federal income taxes and, where applicable, to withholding for Social Security, Medicare, unemployment compensation and state, county and city taxes.

15. Tax Issues. You are hereby advised that the severance amount is likely to be considered taxable income and subject to disclosure to the appropriate taxing authorities. You are hereby advised that you should consult a tax expert with any relevant tax questions. You agree to pay federal or state taxes, if any, which are required by law to be paid with respect to the severance amounts and any other payments or benefits provided under this Agreement. You further agree to indemnify, defend and hold Releasees harmless from any claims, demands, deficiencies, levies, assessments, executions, judgments or recoveries by any governmental entity against Releasees for any amounts claimed due on account of this Agreement.

16. Section 409A Compliance. With respect to any benefits provided under this Agreement that are subject to Section 409A of the Code (“Section 409A”), it is intended that the terms of this Agreement comply with the terms and conditions of Section 409A and the regulations and guidance promulgated thereunder and all provisions of this Agreement shall be construed in a manner consistent with the requirements for avoiding taxes or penalties under

9

Section 409A. If any amount payable under this Agreement is to be paid in two or more installments, for purposes of Section 409A, each installment shall be treated as a separate payment. Any provision that would cause this Agreement to fail to satisfy Section 409A shall have no force and effect until amended to comply with Section 409A. Additionally, if any payment is to be paid at some later time for purposes of Section 409A, the payment date shall be modified accordingly.

17. Severability. If any provision of this Agreement is found by a court of competent jurisdiction to be invalid or unenforceable, the court will modify such provision to the minimum extent necessary to make such provision valid and enforceable or, if that is not possible, the court will strike such provision from this Agreement. The invalidity or unenforceability of any provision of this Agreement will not affect the force, effect, and validity of the remaining provisions of this Agreement.

18. Amendment. This Agreement cannot be amended, modified, waived, discharged or terminated, except in a writing signed both by you and a duly authorized representative of the Company.

19. Entire Agreement. This Agreement, collectively with the your Nondisclosure, Noncompetition, Nonsolicitation and Inventions Agreement with the Company, the Equity Award Agreements and the equity award plans pursuant to which such equity awards were granted, each of which is expressly incorporated by reference herein, contains the entire agreement between you and the Company with respect to the subject matter hereof and shall supersede all other prior and contemporaneous agreements and understandings with respect to such subject matter.

20. Counterparts. This Agreement may be executed in any number of counterparts (including by facsimile or other electronic signature), each of which shall constitute an original and all of which taken together shall constitute one and the same instrument.

21. Governing Law and Consent to Personal Jurisdiction. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Nevada without regard to conflicts of laws provisions thereof. In any legal proceeding arising under this Agreement, venue shall be in Washoe County, Nevada, and you consent to personal jurisdiction in Nevada and Washoe County. The venue choice set forth herein shall not limit or restrict Employer’s right, at its sole discretion, to pursue the equitable, injunctive or specific performance remedies set forth in this Agreement in any jurisdiction or venue where you may be found or where a breach or threatened breach may have or has occurred.

22. Successors and Assigns. This Agreement shall be binding upon the parties hereto and upon their heirs, administrators, representatives, executors, successors, and assigns, and shall inure to the benefit of said parties and each of them and to their heirs, administrators, representatives, executors, successors, and assigns. You expressly warrant that you have not transferred to any person or entity any rights, causes of action, or claims released in this Agreement.

10

23. Notices. All notices, requests, consents, and other communications required or permitted to be given under this Agreement shall be in writing and shall be deemed to have been duly given if delivered personally, or mailed first-class, postage prepaid, by registered or certified mail (notices sent by mail shall be deemed to have been given on the date sent), or by confirmed facsimile transmission or by electronic transmission, with a hard copy deposited in first class mail the same day or the following day, as follows (or to such other address as either party shall designate by notice in writing to the other):

This Employee Nondisclosure, Noncompetition, Nonsolicitation and Inventions Agreement (referred to as the “Agreement”) is entered into on             , 2008, by and between Allied Nevada Gold Corporation (referred to as the “Company”) and me.

I desire to be employed by the Company and the Company desires to employ me; however, as a condition of my employment, the Company requires that I agree to the terms of and execute this Agreement. I understand that if I do not agree to the terms of and execute this Agreement, the Company is unwilling to hire and/or retain me and pay me compensation for my employment.

Accordingly, I agree as follows:

- 1 -
