ExxonMobil to Restructure Holdings in Japan

ExxonMobil and TonenGeneral Sekiyu K.K have entered into an agreement
which will result in the restructuring of ExxonMobil′s holdings in
Japan. Under the terms of the agreement, TonenGeneral Sekiyu will
purchase ExxonMobil′s shares in ExxonMobil Yugen Kaisha, integrating
ExxonMobil Yugen Kaisha′s marketing operations with its existing
manufacturing operations. This will result in a single, integrated
downstream business better positioned to meet Japan′s energy needs. The
transaction is valued at approximately US $3.9 billion.

The corporation anticipates the restructuring will be seamless for
ExxonMobil Japan Group customers, dealers and business partners and
expects existing agreements to remain unchanged. Current management will
remain in place until closing, which will occur in mid-2012.

At closing, ExxonMobil will remain TonenGeneral Sekiyu′s largest
shareholder and anticipates continued participation on its Board of
Directors, subject to shareholder approval of its nominees. TonenGeneral
Sekiyu will have exclusive, long-term use of ExxonMobil′s existing
brands for the sale of ExxonMobil products in Japan. ExxonMobil will
provide ongoing technology support, including technical assistance from
ExxonMobil Research and Engineering. ExxonMobil will also provide
international crude, feedstock and fuels supply services, including
international marine coverage services.

Beyond its retained shareholding in TonenGeneral Sekiyu, ExxonMobil will
maintain its presence in Japan through businesses and partnerships
excluded from the restructuring, including:

• 
  ExxonMobil′s butyl, specialty elastomers, polyolefin, synthetics and
  catalyst businesses, including its ownership in Japan Butyl Company;
  
• 
  International Marine lubricants;
  
• 
  LNG marketing and sales, including LNG market development activities;
  and
  
• 
  Collaborations and partnerships with Japanese companies in the
  upstream sector.
  

ExxonMobil has conducted business in Japan for more than a century. To
strengthen its competitive position in the Japanese market, the company
has continuously innovated and adapted its business model to meet the
needs of Japanese society and its changing business environment.
