5 Approximately 350 km east of the island of Newfoundland on the eastern edge of the Jeanne d Arc Basin, and approximately 50 km from both the Terra Nova and Hibernia fields. Water depth is approximately 120 meters. 2. The WWRP will consist of a concrete gravity structure (CGS) with topsides consisting of drilling facilities, wellheads and support services such as accommodations for 120 to 130 persons, utilities, a flare boom and a helideck. 3. There will be 20 well slots with each slot planned to have two wells each (total well count of 40 wells).

6 Of the planned production wells, 8 are planned to utilize ESPs. The balance of the production wells are planned to be gas-lifted. 4. The primary function of the WWRP is drilling. There will be no oil storage in the CGS. Topsides will be equipped with a test separator. All well fluids will be transported via subsea flowlines to the SeaRose FPSO for processing, storage and offloading. 5. The platform topsides will consist of a drill deck with middle, cellar, and sub decks below. The majority of coiled tubing and coil tubing deployed ESP services will be conducted on the middle deck. 6. Water depths in the White Rose field range from approximately 115 m to 120 m.

7 7. The Grand Banks region has a harsh environment due to the presence of intense mid-latitude low-pressure systems during fall and winter, tropical cyclones in late summer and fall, and sea ice and icebergs in spring. 8. There is a potential for superstructure icing to occur between November and May with the highest potential for freezing spray being in February due to colder temperatures and high wind and wave conditions. 9. Air temperatures in the region range from a minimum of 10 C to a maximum of 20 C. Winds in the area are primarily from the west in winter and southwest in summer, and have been recorded at speeds of up to 51 m/s (99 knots).

8 Request for Information & EOI Husky Energy is requesting that vendor(s) propose system solutions for the electrical submersible pump (ESP) system scope of work outlined within this West White Rose Project (WWRP) ESP Functional Specification . Vendors with responses submitted under the prior RFI will be automatically considered for invitation to bid based on their submitted information. No resubmission is required; but vendors are free to supplement or modify their prior submission if desired. Figure 1: Wellhead Platform (WWRP) tied back to the existing SeaRose FPSO West White Rose Project Functional Specification Electrical Submersible Pumps (ESP) Page 5 of 33 Principal Requirements Alternatively Deployed ESPs In the interest of reducing well workovers and maintaining rig focus on new well delivery, ESP wells will utilize Alternatively Deployed ESPs.

9 Consideration is open only to systems facilitating rigless pump and motor replacement via coil tubing, wireline or slickline. The core focus is maximizing production uptime (through robust ESP design, quick change-out capability, and simplified completion architecture to drive higher reliability). The ability to offer both coil tubing and wireline deployed systems would be considered advantageous. When invitations to bid are issued, Husky Energy may choose to consider only bids associated with a specific deployment technology. Contractual Details Contract Scope ESP contract scope is to include the following: All ESP system components, including.

10 O High efficiency electrical submersible pumps o Associated BHA components o High efficiency electric submersible motors o Protectors o downhole cable o Gas handling o Well Head penetrator o downhole monitoring system Variable Frequency Drives (VFDs) Ability for real-time artificial lift monitoring and optimization Surface power and control solutions Monitoring and maintenance support through the life of the project Responsible for root cause failure analysis Support and Delivery Requirements: The ability to maintain, service and test ESP tools and equipment locally Provide flowchart or outline all potential sub-contractual arrangements, such as for VFDs or other components Discuss/propose how all sub-contracts will be managed, particularly with respect to provision of field and technical product support in the well design phase and for troubleshooting during either installation or product lifetime Ability to meet the required delivery timeline: o EOIs: Q1/Q2 2018 o Contract Award.
