FORWARD-LOOKING STATEMENTS

              The Exhibits incorporated by reference into this Registration Statement contain forward-looking statements concerning anticipated developments in the operations of Ur-Energy Inc. (the “Registrant”) in future periods, planned exploration activities, the adequacy of the Registrant’s financial resources and other events or conditions that may occur in the future. Forward-looking statements are frequently, but not always, identified by words such as “expects,” “anticipates,” “believes,” “intends,” “estimates,” “potential,” “possible” or the negative or other similar expressions, or statements that events, conditions or results “will,” “may,” “could” or “should” occur or be achieved. Information concerning the interpretation of drill results and mineral resource estimates also may be deemed to be forward-looking statements, as such information constitutes a prediction of what mineralization might be found to be present if and when a project is actually developed. Forward-looking statements are statements about the future and are inherently uncertain, and actual achievements of the Registrant or other future events or conditions may differ materially from those reflected in the forward-looking statements due to a variety of risks, uncertainties and other factors, including, without limitation, those described in (i) the Annual Information Form of the Registrant filed as Exhibit 3 to this Registration Statement, (ii) the final short form prospectus filed as Exhibit 75 to this Registration Statement, and (iii) the Supplemental Risk Factors filed as Exhibit 1 to this Registration Statement.

              The Registrant’s forward-looking statements contained in the Exhibits incorporated by reference into this Registration Statement are made as of the respective dates set forth in such Exhibits. Such forward-looking statements are based on the beliefs, expectations and opinions of management on the date the statements are made. In preparing this Registration Statement, the Registrant has not updated such forward-looking statements to reflect any change in circumstances or in management’s beliefs, expectations or opinions that may have occurred prior to the date hereof, nor does the Registrant assume any obligation to update such forward-looking statements in the future. For the reasons set forth above, investors should not place undue reliance on forward-looking statements.

DIFFERENCES IN UNITED STATES AND CANADIAN REPORTING PRACTICES

              The Registrant is permitted, under a multi-jurisdictional disclosure system adopted by the United States, to prepare this report in accordance with Canadian disclosure requirements, which are different from those of the United States. The Registrant prepares its financial statements, which are filed with this report on Form 40-F in accordance with Canadian generally accepted accounting practices (“GAAP”), and they may be subject to Canadian auditing and auditor independence standards. Such financial statements may not be comparable to financial statements prepared in accordance with United States GAAP. Significant differences between Canadian GAAP and United States GAAP pertaining to the Registrant are described in Note 15 to the Audited Annual Consolidated Financial Statements for the years ended December 31, 2006 and 2005, which are filed as Exhibit 10 to this Registration Statement.

RESOURCE AND RESERVE ESTIMATES

              The terms “Mineral Reserve”, “Proven Mineral Reserve” and “Probable Mineral Reserve” are Canadian mining terms as defined in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”), which references the guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) CIM Standards on Mineral Resources and Mineral Reserves, adopted by the CIM council, as may be amended from time to time by the CIM. These definitions differ from the definitions in the United States Securities and Exchange Commission (the “Commission”) Industry Guide 7 (“Industry Guide 7”) under the United States Securities Act of 1933, as amended. Under Industry Guide 7 standards, a “final” or “bankable” feasibility study is required to report reserves, the three-year historical average price is used in any reserve, or cash flow analysis to designate reserves, and the primary environmental analysis or report must be filed with the appropriate governmental authority.

              In addition, the terms “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under Industry Guide 7 and normally are not permitted to be used in reports and registration statements filed with the Commission. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves. “Inferred mineral resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases.

              Accordingly, information contained in this report and the documents incorporated by reference herein containing descriptions of our mineral deposits is not comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.

DOCUMENTS FILED PURSUANT TO GENERAL INSTRUCTIONS

              In accordance with General Instruction B.(1) of Form 40-F, the Registrant hereby incorporates by reference Exhibits 1 through 90 as set forth in the Exhibit Index attached hereto.

              In accordance with General Instruction C.(2) of Form 40-F, the Registrant hereby incorporates by reference: (i) Exhibit 10, the Audited Annual Consolidated Financial Statements of the Registrant for the years ended December 31, 2006 and 2005, including a reconciliation to United States GAAP as required by Item 17 of Form 20-F, (ii) Exhibit 4, Management’s Discussion and Analysis for the year ended December 31, 2006, all as set forth in the Exhibit Index attached hereto.
