Unit Offering

Each Unit will consist of one common share in the capital of the Company (a "Common Share") and one-half of one transferable common share purchase warrant of the Company (each whole warrant, a "Warrant"). Each Warrant is exercisable to acquire one Common Share (a "Warrant Share") at an exercise price of USD$2.00 per Warrant Share for 24 months after issuance. The Warrants will not be listed.

In addition, Denison has agreed to grant to the Underwriters an over-allotment option (the "Over-Allotment Option") exercisable, in whole or in part, at the sole discretion of the Underwriters to purchase up to an additional 4,120,950 Units at the Issue Price for a period of up to 30 days after the closing of the Unit Offering, for potential additional gross proceeds to Denison of up to approximately USD$3.75 million .

Proceeds of the Unit Offering are anticipated to be used to fund evaluation and environmental assessment activities on Denison's Wheeler River Uranium Project, including the proposed Phoenix in-situ recovery uranium mining operation ("Phoenix"), as well as for general working capital purposes. Subject to a decision to advance to a formal Feasibility Study ("FS") for Phoenix , the proceeds from the Unit Offering and current working capital are expected, based on current estimates, to be sufficient to complete such FS process.

Denison will pay to the Underwriters a cash commission equal to 6% of the gross proceeds of the Unit Offering, including any proceeds received from the exercise of the Over-Allotment Option.
