employed. The Corporation has consistently applied its ROCE definition for many years and views it as the best measure of historical capital
productivity in our capital-intensive, long-term industry, both to evaluate management’s performance and to demonstrate to shareholders that
capital has been used wisely over the long term. Additional measures, which are more cash-flow based, are used to make investment decisions.

LIQ U I D S AND N AT U R A L G AS PRO V E D R E S E R VES
In this report, we use the term “proved reserves” to mean quantities of oil and gas that ExxonMobil has determined to be reasonably certain of
recovery under existing economic and operating conditions on the basis of our long-standing, rigorous management review process. We only
book proved reserves when we have made significant funding commitments for the related projects. In this report, we aggregate proved reserves
of consolidated and equity companies, excluding royalties and quantities due others, since ExxonMobil does not view these reserves differently
from a management perspective. To reflect management’s view of ExxonMobil’s total liquids reserves, proved reserves in this report also include
oil sands reserves from Canadian Syncrude operations, which are reported separately as mining reserves in our Form 10-K and proxy statement.
Oil sands reserves included in this report totaled 694 million barrels at year-end 2007, 718 million barrels at year-end 2006, 738 million barrels
at year-end 2005, 757 million barrels at year-end 2004 and 781 million barrels at year-end 2003. For our own management purposes and as
discussed in this report, we determine proved reserves based on price and cost assumptions that are consistent with those used to make
investment decisions. Therefore, the proved reserves in this report are not directly comparable to the data reported in our Form 10-K and proxy
statement. Based on regulatory guidance, ExxonMobil began in 2004 to state our results in the Form 10-K and proxy statement to reflect the
impacts on proved reserves of utilizing December 31 liquids and natural gas prices (“year-end price/cost effects”). On this basis, year-end proved
reserves, including year-end price/cost effects, totaled 22.5 billion oil-equivalent barrels in 2007, 22.8 billion oil-equivalent barrels in 2006,
22.4 billion oil-equivalent barrels in 2005 and 21.7 billion oil-equivalent barrels in 2004. Excluding year-end price/cost effects, 2007 proved
reserves totaled 22.7 billion oil-equivalent barrels, 2006 proved reserves totaled 22.7 billion oil-equivalent barrels, 2005 proved reserves totaled
22.4 billion oil-equivalent barrels, while 2004 proved reserves totaled 22.2 billion oil-equivalent barrels.

Resources, resource base, recoverable oil, recoverable hydrocarbons, recoverable resources, and similar terms used in this report are the total
remaining estimated quantities of oil and gas that are expected to be ultimately recoverable. In addition to proved reserves, the resource base
includes quantities of oil and gas that are not yet classified as proved reserves, but which ExxonMobil believes will likely be moved into the proved
reserves category and produced in the future.
PROVED R E S E RVES R E PL AC E M E N T R AT IO
Proved reserves replacement ratio is a performance measure that is calculated using proved oil-equivalent reserves additions divided by
oil-equivalent production. Both proved reserves additions and production include amounts applicable to equity companies. The ratio usually
reported by ExxonMobil excludes sales and year-end price/cost effects, and includes Canadian oil sands mining operations in both additions
and production volumes. See the definition of “liquids and natural gas proved reserves” above.
FINDI N G AND R E SOURC E -AC QUISIT I O N CO S T S
Finding and resource-acquisition costs per oil-equivalent barrel is a performance measure that is calculated using the Exploration portion of
Upstream capital and exploration expenditures and proved property acquisition costs divided by resource additions (in oil-equivalent barrels).
ExxonMobil refers to new discoveries and acquisitions of discovered resources as resource additions. In addition to proved reserves, resource
additions include quantities of oil and gas that are not yet classified as proved reserves, but which ExxonMobil believes will likely be moved into
the proved reserves category and produced in the future.
