If the above information is correct, we offer to drill, load and blast at the cost of $3.70 per in bank cubic yard. We request you supply fuel for the drills. Fuel consumption for two drills on site would be approximately between 75-100 gallons per day. We will supply all other equipment, labor, and material, along with required insurances and MSHA compliance, (5000- 23). Mobilization to the project for two drills and other supplies will be $7500.00 and is due upon our mobilization to the project. We request verification from your company to either supply explosive storage magazines, or provide us with an area meeting BATF requirements pertaining to safe storage locations of explosives storage magazines. We are able to supply explosive storage magazines if none can be provided. In the event drilling and blasting operations encounter water in the boreholes, whether through inclement weather or ground water infiltration, and specialized wet hole explosive product is needed, the cost of the product will be billed separately from the line item at invoiced materials cost, plus delivery fee, plus 20% markup.

February 4, 2021 Energy Fuels Resources (USA) Inc. Attn: Steve Hancock 6425 S Highway 191 Blanding UT 84511 Dear Steve, 3401 33rd Street Southwest Po Box 9559 Fargo, ND 58106-9559 Phone (701) 232-0033 Fax (701) 298-1717 Thank you for the invitation to quote Energy Fuels Resources (Energy) the equipment needed for their mining project in Blanding, Utah. North Central Rental & Leasing, (NCRL) respectfully submits our proposal for a maintained fleet of Caterpillar machines. Listed on Attachment A, you will find the models, quantities, monthly rental rates, hours allowed per month, excess hour charge, guaranteed number of months rates are based upon, total freight charges and the maintenance rate per hour for materials only. All rates shown on Attachment A do not include any state, local, property or any other taxes that may be applicable. Rates are based upon electric hour meter readings that are attached to the dash of each machine. Rates are based on 176 hours of use each month. Excess hour charges, if any, will be calculated and invoiced at the end of the project. There would be no credit issued for any hours under the allowed during the term of this proposal. If Energy elects to double shift machines, then NCRL would invoice those hours at the end of each month. (To figure the double shift rates, take the excess hour rate shown on Attachment A times the number of hours). Rates are based upon a minimum guarantee of 12 months and a package deal. This quote is valid for 90 days. *NOTE: Along with the majority of the rental industry, we have changed our hours allowed to 160 hours per 4 weeks instead of 176. This resulted in a change in our excess hour rates, however this quote is based upon 176 hours allowed per 4 weeks. Maintenance and Repairs: Maintenance: The maintenance rates per hour listed on Attachment A includes the material part items only, such as oil filters, lubricant oils, grease, anti-freeze, batteries, fan belts, lights and make-up oils. NCRL would invoice Energy actual hours used on machines February 4, 2021 Energy Fuels Resources (USA) Inc. Page2 at the end of each month. Our monthly maintenance charge would be $94,750.00 which includes our labor, specialized lube trucks, support vehicles and equipment, specialized tooling, scheduled oil sampling, parts trailers and inventories, mileage and travel expense. NCRL will provide two (2) full-time maintenance technicians on site fifty (50) hours per week on a schedule to be determined, Monday through Friday. Energy would have to schedule the machines available for a time frame yet to be determined adequate for NCRL maintenance personnel to perform the required maintenance. NCRL would invoice Energy for the monthly maintenance charge at the start of each month. Repairs: NCRL would be responsible for all repairs including parts and labor on our machines other than failures caused by damages or mis-use. Repairs include items as minor as starters, alternators, water pumps, hydraulic hoses, etc. to the major items such as engines, transmissions, differentials, brakes, hydraulic pumps and cylinders, etc. If time permits and Energy requests NCRL's technician to perform repairs or maintenance on their machines, our hourly charge would be $140.00 per hour for standard time, $178.00 per hour for overtime and $205.00 per hour for Sundays and holidays plus materials. Mobilization, Freight and Assembly Charges: Mobilization: The mobilization charge of $57,250.00 includes the moving expense of our support personnel, set up the job site, and transportation costs of our vehicles, parts and tooling inventory to the job site. NCRL would charge the same amount to demobilize at the end of the project. Freight and Assembly Cbarges: The freight and assembly charges listed on Attachment A are based upon all machines shipped by truck to the job site. Energy would be responsible for demobilization including disassembly and return freight on all machines, parts, vehicles and equipment, at the end, or at any time during the rental period to Rapid City, SD. NCRL would be responsible for freight to the job site for all stock order parts shipments, emergency repair parts, maintenance parts, G.E.T. and bulk oil shipments. Once the equipment has been delivered and assembled, an inspection would take place. During the inspection, a representative ofNCRL and a representative of Energy will verify on the Acceptance Report the condition of the equipment. Energy'' Responsibilities Include: Operators: Provide the operators as needed to operate the machines as stated in Caterpillar's operating guide. NCRL will provide, at no expense to Energy, qualified training instructors for the purposes of training operators. This training would take place on the jobsite at the initial start up of the job and would include classroom, walk around, and in iron demonstrations. Fuel: Supply and fill all fuel for equipment including NCRL's service vehicles. February 4, 2021 Energy Fuels Resources (USA) Inc. Page3 Damages: This includes glass breakage, bent handrails, stepladders, fenders, etc. NCRL's normal policy for repairing damages to rental machines is to repair them when the rental period is completed, however, if the damaged item is of a safety concern, we would repair the damages as soon as possible after they occurred. An itemized list of the parts and labor required would be , provided to Energy prior to starting the repair, and invoiced at current list prices plus freight upon completion. Undercarriage and Tires: Energy would be responsible for all tire wear including tire damages on the machines with an asterisk listed on Attachment A. Equipment would have to be returned with same brand and model tires as when delivered, or prorated accordingly by percentage of tire wear and condition at termination of rental period. Upon delivery of machines, a representative of NCRL/BMC, a representative of Energy and a representative from an independent tire dealer or manufacturer would jointly verify in writing the condition, percentage of wear, and tire value. Upon termination of rental, we would again have the representatives mentioned above determine the condition, percentage of wear, and tire values. Any differences noted, would then be charged or credited to Energy including both materials and labor. Undercarriage wear on all track type machines would be NCRL's expense. Ground Engaging Tools: Energy would be responsible for all parts relating to ground engaging tools (G.E.T.), i.e. cutting edges, ripper tips and protectors, bucket tips and adapters, edges between adapters, wear plates on bottom of buckets and all mounting hardware. NCRL would install these items on an as needed basis at the current Caterpillar list price plus freight at no additional labor costs. All machines would be delivered with new G.E.T. items and are to be returned with new. Rates and conditions would be subject to change at time of commitment. We wish to thank Energy Fuels Resources and you for giving us the opportunity to present our proposal and for all the consideration we receive.
