### COMMUNICATION PLAN
EXPLORATION DRILLING PROGRAM CHUKCHI SEA , ALASKA

The following Communication Plan will be used during each exploration drilling season to coordinate activities with local subsistence users, including the Alaska Eskimo Whaling Commission (AEWC),
Eskimo Walrus Commission ( E WC), Alaska Nanuuq Commission (ANC), Alaska Beluga Whale Committee (ABWC), Ice Sea l Committ ee (IS C ), and village Whaling Captains Associations (WCA).

E ach planned drilling season in the Chukchi Sea will begin with transit through the Bering Strait into the
Chukchi Sea on or a b out July 1, then on location at a drill site on or about July 4 and en d on or about
October 31. 1

The Communications Plan will be implemented in two phases. Phase I describes the guidelines already in place to ensure proper communication during the drilling season. Phase II describes what to do in the

event Shell Gulf of Mexico Inc. ( Shell ) activities potentially affect subsistence activities and how to keep subsistence user groups informed of Shell activities. Phase I and II are designed to minimize the potential
for interference of Shell activities with subsistence activ ities and resources and to keep operators up

- to

date regarding the timing and status of the beluga and bowhead whale migration s in the Chukchi Sea as well as the timing and status of other subsistence hunts.

Drilling program operations will be performed in compliance with all applicable permits and authorizations, including the Plan of Cooperation (POC)

, M arine Mammal Protection Act (MMPA) authorizations issued by the U.S. Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service (NMFS) and Lease Stipulation # 5 from Chukchi Sea lease sale 19 3 per the Bureau of Ocean Energy Managemen t (BOEM)

. 

### PHASE I

• Shell will fund the operation of Communication and Call Centers (Com Centers) in the coastal villages to enable communications between Shell operations and vessels, local subsistence users, and Subsistence Advisors (SA), thereby notifying the subsistence community of any vessel transit route changes and avoiding conflicts with subsistence activities.

• Protected Species Observers ( PS O) will be onboard exploration drilling

- related vessels with responsibilities to ; monitor for the presence of m arine mammals, assist with the maintenance of marine mammal safety radii around vessels, monitor and record avoidance or exposure behaviors, and communicate with the Com Centers and local subsistence hunters by marine radio.

• If a conflict arises with offsh ore activities, the PSO will immediately contact the vessel captain and the Com Centers. The Com Centers will then contact Shell’s simultaneous operations emergency response team. If avoidance is not possible, the next phase will include communication between a Shell representative and a representative from the impacted subsistence hunter group(s) to resolve the issue and plan an alternative course of action by either industry or the subsistence groups.

• Shell will employ local SAs from the Chukchi Sea v illages that may be potentially impacted by Shell’s exploration drilling activities. The SAs will provide consultation and guidance regarding whale migration and subsistence activities. There will be one SA per village, working

The subsistence advisor s will use local knowledge (Traditional Knowledge) to gather data on subsistence lifestyle within the community and provide advice on ways to minimize and mitigate potential negati ve impacts to subsistence resources during each drilling season. Responsibilities will include reporting any subsistence concerns or conflicts

, coordinating with subsistence users

, reporting subsistence related comments, concerns, and information

, coordina ting with the Com and Call Center personnel

, and advising on how to avoid subsistence conflicts.

• Aircraft traffic will not fly below 1,500 ft

. (457 m) altitude (except during takeoffs and landings, in emergency situations or for PSO overflights) while over land or sea. If flights need to deviate from their routine planned routes due to an emergency , weather or other unavoidable reasons, the new flight information will be shared as outlined by Shell ’s Health, Safety , Security, and Environment (HSSE) requirem ents with Com Centers so area sub sistence users can be notified.



### • Regular overflight surveys and support vessel surveys for marine mammals will be conducted to further monitor prospect areas and identify areas currently being used for subsistence activities to avoid potential conflicts with users.



### PHASE II

All guidelines in Phase I will be adhered to in addition to the following:

• If potential conflicts are identified between Shell activities and subsistence activities; the Com Center Action Plan will be used to manage the issue.

• Shell will continue with engagements and regular communications with the AEWC, E WC, ANC, ABWC, ISC, and the WCAs of Barrow, Wainwright, Point Lay and Point Hope once transiting of vessels begins through the Chukchi Sea, during drillin g activities, and during mobilization from
the Chukchi Sea.
