Item 1.01             Entry into a Material Definitive Agreement

Merger Agreement

On January 4, 2015, Uranerz Energy Corporation, a Nevada corporation (“Uranerz” or the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Energy Fuels Inc., an Ontario corporation (“Energy Fuels”), and EFR Nevada Corp., a Nevada corporation and wholly owned subsidiary of a subsidiary of Energy Fuels (“Merger Sub”). The Merger Agreement provides for a business combination whereby Merger Sub will merge with and into the Company (the “Transaction”), and as a result the Company will continue as the surviving operating corporation and as an indirectly wholly owned subsidiary of Energy Fuels. A copy of the Merger Agreement was filed with the Securities and Exchange Commission on January 12, 2015 pursuant to an amendment to the Company’s current report on Form 8-K originally filed on January 5, 2015.

Amendment to Merger Agreement

On May 8, 2015, Uranerz, Energy Fuels and Merger Sub entered into an Amendment to the Agreement and Plan of Merger to amend Sections 1.3, 3.2(h), 4.23, and 7.13 of the Merger Agreement (the “Amendment Agreement”). The Amendment Agreement modified the number of Uranerz nominees Energy Fuels is required to appoint to its board of directors and modified the total number of members of the Energy Fuels board of directors after the closing of the Transaction. The Merger Agreement originally provided for the appointment of 3 Uranerz nominees, Dennis Higgs, Glenn Catchpole and Paul Saxton, while the Amendment Agreement only requires the appointment of Dennis Higgs and Glenn Catchpole. The execution of the Amendment Agreement reflects a determination by Energy Fuels in March 2015 to adjust the size of its board of directors following the completion of the Transaction such that its board of directors would be comprised of 8 members, versus a minimum of 9 directors as originally contemplated. In order to reflect the reduced size of the board and to retain substantial representation on its board, Energy Fuels requested, and Uranerz agreed, to reduce the number of Uranerz nominees on the board of Energy Fuels post-Transaction from 3 directors to 2 directors. The Amendment Agreement further requires the board of directors of Energy Fuels to be comprised of eight directors while the Merger Agreement originally stated that the Energy Fuels board of directors would consist of at least 9 members.

In addition, the Amendment Agreement provides for withholding of taxes for holders of Uranerz warrants who are subject to FIRPTA withholding as well as a revised process for withholding of FIRPTA taxes for holders of shares of Uranerz common stock (who do not also holder Uranerz warrants). Pursuant to the Amendment Agreement:

• Energy Fuels and any holder of shares of Uranerz common stock (who does not also hold Uranerz warrants) subject to FIRPTA withholding will direct the exchange agent for the Transaction to withhold 10% of the Energy Fuels common shares issuable to such holder of shares on completion of the Transaction (the “Withheld Shares”) on account of the amount to be withheld under the Internal Revenue Code and any other applicable tax laws (the “Withholding Amount”);

• The exchange agent for the Transaction will sell the Withheld Shares to fund the Withholding Amount;

• Energy Fuels will pay all Withholding Amounts to the IRS and other government authorities under applicable tax laws;

• Such holders will have no further interest in the Withheld Shares;

• Such holders will have no obligation to Energy Fuels in the event that the amount realized is less than the Withholding Amount; and

• Energy Fuels will have no obligation to such holders to remit to such holders any proceeds of sale derived from the sale of the Withheld Shares and such holder will have no entitlement to such amounts.

A copy of the Amendment Agreement is filed as an Exhibit hereto. The foregoing description of the Amendment Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Amendment Agreement.
