This presentation includes forward-looking statements. Actual future conditions (including economic conditions, energy demand, and energy supply) could differ materially due to changes in technology, the development of new supply sources, political events,demographic changes, and other factors discussed herein (and in Item 1A of ExxonMobil’s latest report on Form 10-K or information set forth under "factors affecting future results" on the "investors" page of our website at www.exxonmobil.com). This material is not to bereproduced without the permission of Exxon Mobil Corporation.

• Meeting the IMO’s 2050 GHG reduction targets requires engine builders to deliver significant efficiency improvements

• These targets will not be met without change

• To achieve this, many operational fundamentals are changing now

• This results in higher operating pressures and combustion temperatures

The current landscape

Next-generation marine engines requirenext-generation lubricants

More severe engine conditions create a much harsher operating environment for lubricating oils

Today’s cylinder oils will struggle to work under this pressure

Inadequate lubricant performance does not provide sufficient engine cleanliness and protection, resulting in

All risks operators simply cannot afford

Lubricant-related engine damage

Higher maintenance costs

Increased engine downtime

Today’s new engine designs require cylinder oils to ‘do more’:⇒ Lubrication is a critical factor in helping newer, more efficient engines achieve optimum performance

The demand on cylinder oils is evolving

More importantDeposit controlDetergencyOxidation stabilityWear protection

Less importantAcid neutralisation

This is critical today, given engines are already being built for vessels that will still be sailing in 2050

Various alternative fuel options• Safe. Scalable. Reliable. Viable

• Evaluation criteria• Sound technical analysis• Climate & environmental impacts • Whole life cycle of fuels and ships• Fuel cost• Potential impact on global trade

• Several options may need to co-exist • Different shipping subsectors• Encourage R&D

HFO to VLSFOSo what happened ??A number of cases were observed, both in the transition period, end 2019 as well as beginning of 2020 after the fuel in use were switched.

o Fuel tank cleaning prior to bunkering VLSFOo Fuel handling issues because of the lower viscosity of the new fuels

o Cylinder liner scuffing typical because ofo Cat. Fines

High wear to ring and liner, high concentration of Iron in the oil filmo Wear down of cermet coating

Wear down of the cermet, expose the cast iron base material, seizures and scuffing

o Under lubrication Decreasing the feed rate to rapidly, not securing that the lubricators give enough

oil.
