Re: Allied Nevada Gold Corp. - Lock-Up Agreement 

Dear Sirs: 
 This Lock-Up Agreement is being
delivered to you in connection with the Securities Purchase Agreement (the “Purchase Agreement”), dated as of December 9, 2014 by and among Allied Nevada Gold Corp., a Delaware corporation (the “Company”) and
the investors party thereto (the “Buyers”), with respect to the issuance of shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”). Capitalized terms used herein and not otherwise
defined herein shall have the respective meanings set forth in the Purchase Agreement. 
 In order to induce the Buyers to enter into the
Purchase Agreement, each undersigned agrees that, commencing on the date hereof and ending on the date sixty days following the Closing Date (the “Lock-Up Period”), the undersigned, without the prior written consent of H.C.
Wainwright & Co., LLC, will not, and will cause all affiliates (as defined in Rule 144 promulgated under the Securities Act of 1933, as amended) of the undersigned or any person in privity with the undersigned or any affiliate of the
undersigned not to, (i) offer, sell, offer to sell, contract or agree to sell, hypothecate, pledge, sell or grant any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend,
make any short sale or otherwise transfer or dispose of or agree to dispose of, directly or indirectly, any shares of Common Stock or Common Stock Equivalents, or establish or increase a put equivalent position or liquidate or decrease a call
equivalent position within the meaning of Section 16 of the Securities and Exchange Act of 1934, as amended and the rules and regulations of the Securities and Exchange Commission promulgated thereunder with respect to any shares of Common
Stock or Common Stock Equivalents owned directly by any of the undersigned (including holding as a custodian) or with respect to which any of the undersigned has beneficial ownership within the rules and regulations of the Securities and Exchange
Commission (collectively, the “Undersigned’s Shares”), or (ii) enter into any transaction that would have the same effect, or enter into any swap, hedge or other arrangement that transfers to another, in whole or in part,
any of the economic consequences of ownership of any of the Undersigned’s Shares, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of shares of Common Stock or other securities, in cash
or otherwise, (iii) make any demand for or exercise any right or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any shares of Common Stock or Common Stock Equivalents or
(iv) publicly disclose the intention to do any of the foregoing. 
 The foregoing restriction is expressly agreed to preclude the
undersigned, and any affiliate of the undersigned and any person in privity with the undersigned or any affiliate of the undersigned, from engaging in any hedging or other transaction which is designed to or which








 
reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Shares even if the Undersigned’s Shares would be disposed of by someone other than the
undersigned. Such prohibited hedging or other transactions would include, without limitation, any short sale or any purchase, sale or grant of any right (including, without limitation, any put or call option) whether or not with respect to any of
the Undersigned’s Shares or whether or not with respect to any security that includes, relates to, or derives any significant part of its value from the Undersigned’s Shares. 

Notwithstanding the foregoing, the undersigned may transfer (i) the Undersigned’s Shares as a bona fide gift or gifts,
provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, or (ii) the Undersigned’s Shares to any trust for the direct or indirect benefit of the undersigned or the immediate family of the
undersigned, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value. For purposes of this Lock-Up Agreement,
“immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. The undersigned now has, and, except as contemplated by the immediately preceding sentence, for the duration of this
Lock-Up Agreement will have, good and marketable title to the Undersigned’s Shares, free and clear of all liens, encumbrances, and claims whatsoever. The undersigned also agrees and consents to the entry of stop transfer instructions with the
Company’s transfer agent (the “Transfer Agent”) and registrar against the transfer of the Undersigned’s Shares except in compliance with the foregoing restrictions. 

In order to enforce this covenant, the Company shall impose irrevocable stop-transfer instructions preventing the Transfer Agent from
effecting any actions in violation of this Lock-Up Agreement. 
 Each of the undersigned acknowledges that the execution, delivery and
performance of this Lock-Up Agreement is a material inducement to each Buyer to complete the transactions contemplated by the Purchase Agreement and that the Company shall be entitled to specific performance of such undersigned’s obligations
hereunder. Each undersigned hereby represents that such undersigned has the power and authority to execute, deliver and perform this Lock-Up Agreement, that such undersigned has received adequate consideration therefor and that such undersigned will
indirectly benefit from the closing of the transactions contemplated by the Purchase Agreement. The undersigned hereby represent that there are no other affiliates of the undersigned that hold securities of the Company. 

Each undersigned understands and agrees that this Lock-Up Agreement is irrevocable and shall be binding upon such undersigned’s heirs,
legal representatives, successors, and assigns. 
 This Lock-Up Agreement may be executed in two counterparts, each of which shall be deemed
an original but both of which shall be considered one and the same instrument. 
 This Lock-Up Agreement will be governed by and construed
in accordance with the laws of the State of New York, without giving effect to any choice of law or conflicting provision or rule (whether of the State of New York, or any other jurisdiction) that would cause the laws of any jurisdiction other than
the State of New York to be applied. In furtherance of the foregoing, the internal laws of the State of New York will control the interpretation and construction of this Lock-Up Agreement, even if under such jurisdiction’s choice of law or
conflict of law analysis, the substantive law of some other jurisdiction would ordinarily apply.
