Amendment to Agreement and Plan of Merger

On March 3, 2015, Coeur Mining, Inc. (“Coeur”), Hollywood Merger Sub, Inc. (“Merger Sub”), a wholly-owned subsidiary of Coeur, Paramount Gold and Silver Corp. (“Paramount”) and Paramount Nevada Gold Corp., a wholly-owned subsidiary of Paramount (“SpinCo”), entered into an Amendment to Agreement and Plan of Merger (the “Amendment”) to the previously disclosed Agreement and Plan of Merger, dated as of December 16, 2014 (the “Merger Agreement”), by and among Coeur, Merger Sub, Paramount and SpinCo. Pursuant to the Merger Agreement, Merger Sub will merge with and into Paramount, with Paramount surviving as the wholly-owned subsidiary of Coeur (the “Merger”). Pursuant to the Amendment, the condition to closing that each of Coeur and Paramount shall have received a written opinion from their respective counsel to the effect that the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), was amended so that the condition now requires that the parties shall have received a written opinion to the effect that the Merger should qualify as a “reorganization” within the meaning of Section 368(a) of the Code. In addition, the maturity of the promissory note providing for a loan from Coeur to Paramount at the closing of the Merger was increased from one year to five years. Other than expressly modified pursuant to the Amendment, the Merger Agreement remains in full force and effect.

The foregoing description of the Amendment is not a complete description of all of the parties’ rights and obligations under the Merger Agreement or the Amendment. The above description is subject to, and qualified in its entirety by reference to the Merger Agreement, which was filed as Exhibit 2.1 to the Current Report on Form 8-K filed with the United States Securities and Exchange Commission (the “SEC”) by Coeur on December 18, 2014, and the Amendment, which is filed as Exhibit 2.1 hereto and is incorporated herein by reference.
