                      [Exxon Mobil Corporation Letterhead]

                                  May 21, 2002

Dear Investor:

Last month, you received the notice and proxy statement for ExxonMobil's 2002
annual meeting of shareholders to be held on May 29. In addition to the election
of directors and ratification of auditors, there are eight shareholder proposals
on the agenda for this year's meeting. For the reasons we give in the proxy
statement, our board recommends a vote for our director nominees and
ratification of our auditor and recommends a vote against each of the
shareholder proposals.

Institutional Shareholder Services (ISS) recently issued its voting
recommendations for our 2002 meeting. ISS recommends a vote for ExxonMobil's
board nominees and ratification of our auditor and against five of the eight
shareholder proposals. However, this year ISS recommends a vote for three of the
shareholder proposals: Item 8 (Renewable Energy Sources), Item 9 (Amendment of
EEO Policy), and Item 10 (Shareholder Vote on Poison Pills).

The shareholder proposals on renewables and EEO policy are repeat proposals
that have appeared in ExxonMobil's proxy statements in substantially the same
form before. In both 2000 and 2001, ISS supported ExxonMobil's board in
recommending a vote against the proposals.

I cannot comment as to why ISS has changed their recommendation on these repeat
proposals this year. However, I can assure you that from ExxonMobil's
perspective nothing has changed that would warrant a change in vote. With
respect to the renewables proposal (Item 8), while we do not believe
renewables represent a sound investment at this time, we continue to be actively
engaged in these issues; to develop new, better, and cleaner products and
technologies; to improve the environmental performance of our own operations;
and to keep our shareholders and others informed of our views and actions. With
respect to the EEO proposal (Item 9), we continue to believe that we have
already adequately addressed the proponent's concerns, and have in fact taken
additional steps in the past year to make that even more clear.

Of the votes cast at last year's meeting, over 91% were cast against the
renewables proposal and over 87% were cast against the EEO proposal. If, like
the great majority of our shareholders, you have voted against these proposals
in the past, I urge you to continue to do so this year despite the change at
ISS. If you have voted for these proposals in the past, I urge you to reconsider
that vote for the reasons we give in the proxy statement.

I would also like to comment on the poison pill proposal (Item 10), for which
ISS also recommends a vote in favor. This is a new proposal for ExxonMobil this
year. We understand that a number of investors have voting guidelines under
which they generally support these kinds of proposals. However, before you make
a voting decision on this proposal for ExxonMobil, I urge you to consider our
response in the proxy statement carefully. As we explain more fully in that
response, we have no poison pill and no plans to adopt one; we consider it
unlikely that our board would ever be called upon to consider adopting a pill;
and, in fact, we support the principle of shareholder voting on rights plans.
Although our board believes this particular proposal is imprecise and overly
restrictive and therefore cannot support it, we believe there is significant
common ground between our views and the views of the proponent on this issue. We
also believe that our position is significantly different from the positions
taken by most other companies facing this proposal, and that our position
deserves your support with a vote against the shareholder proposal even if that
vote would represent an exception to your normal voting policy.

My comments in this letter are of course subject to the more detailed statements
of the board's positions in our proxy statement, and I refer you to that
document for more information. Please also call me directly at (972) 444-1538 if
you have any questions.
