Amendment No. 14 Relating to the Purchase Agreement

     As previously reported, on October 31, 2008, PolyMet Mining Corp., a corporation existing under the laws of British Columbia (the “Company”), entered into a purchase agreement, as amended (the “Purchase Agreement”), with Poly Met Mining, Inc., its wholly-owned subsidiary (the “Issuer”), and Glencore, AG (the “Purchaser”), pursuant to which, among other things, (1) the Issuer agreed to issue Floating Rate Secured Debentures due September 30, 2011 (each, a "Debenture" and collectively, the "Debentures") in five separate tranches, consisting of four Debentures in the aggregate principal amount of US$25,000,000 and a fifth Debenture in the principal amount of US$25,000,000 (the "Original Tranche E Debenture"), in each case to be issued and delivered by the Issuer and paid for by the Purchaser upon fulfillment or waiver of certain conditions set forth therein; and (2) the Company issued a warrant, exercisable from time to time (the "Exchange Warrant"), to purchase common shares of the Company, without par value, in an amount equal to the principal amount of the Debentures divided by US$4.00. The first Debenture in the original principal amount of US$7,500,000 (the "Tranche A Debenture") was issued to the Purchaser on October 31, 2008; (2) the second Debenture in the original principal amount of US$7,500,000 (the "Tranche B Debenture") was issued to the Purchaser on December 24, 2008; (3) the third Debenture in the original principal amount of US$5,000,000 (the "Tranche C Debenture") was issued to the Purchaser on June 18, 2009; and (4) the fourth Debenture in the original principal amount of US$5,000,000 (the "Tranche D Debenture" and together with the Tranche A Debenture, Tranche B Debenture and Tranche C Debenture, the "Outstanding Debentures") was issued to the Purchaser on September 2, 2009.

     On November 12, 2010, the Company, the Issuer and the Purchaser entered into an Amendment and Waiver, pursuant to which, among other things, (1) the maturity date of each of the Outstanding Debentures and the expiration date of the Exchange Warrant were extended from September 30, 2011 to September 30, 2012, and (2) any and all obligations of the Issuer to issue the Original Tranche E Debenture and any and all obligations of the Purchaser to purchase the Original Tranche E Debenture pursuant to the Purchase Agreement were terminated and discharged in all respects (the "Original Tranche E Debenture Termination"). On November 30, 2011, the Company, the Issuer and the Purchaser entered into an Amendment and Waiver, dated as of November 30, 2011 (the "2011 Amendment and Waiver"), pursuant to which, among other things, the maturity date of each of the Outstanding Debentures was extended from September 30, 2012 to the earlier to occur of certain events or September 30, 2014.

     On April 10, 2013, the Company, the Issuer and the Purchaser entered into Amendment No. 14 Relating to the Purchase Agreement ("Amendment No. 14") pursuant to which the Original Tranche E Debenture Termination was rescinded and the Issuer agreed to issue to the Purchaser a fifth secured Debenture in the principal amount of US$20,000,000 (the "Amended Tranche E Debenture") due the day which is the earlier of (i) the completion of the a US$60,000,000 rights offering by the Company or (ii) May 1, 2014. The sale of the Amended Tranche E Debenture was consummated on April 11, 2013.

The Amended Tranche E Debenture carries a fixed interest rate of 4.721% per annum. The Amended Tranche E Debenture contains certain events of default that are customarily included in financings of this nature. If an event of default occurs, the Purchaser may declare all of the then outstanding Principal Amount of the Amended Tranche E Debenture, including any accrued and unpaid interest, to be due and payable immediately.
