CLEANUP STATUS

Under the direction of the Unified Command, almost 700 people are now
involved in the response and cleanup effort including ExxonMobil′s North
America Regional Response Team, the Clean Harbors and ER oil spill
response organizations and additional contractors.

We have deployed more than 43,000 feet of boom and approximately 260,000
absorbent pads to clean up oil adjacent to the river. Deployment
continues to focus on the highest priority areas to reduce environmental
impact. Forty-six boats are available for deployment on the river when
conditions permit, and air boats are being used to help ferry workers to
and from the shore to various cleanup sites where conventional
motorboats cannot be used.

The EPA is leading the Unified Command Center cleanup activities and
conducting ongoing air and water quality monitoring. Ongoing air quality
monitoring has confirmed there is no danger to public health. Municipal
water systems continue to be monitored by the EPA; no reports of impacts
have been received to date. For additional information, please visit www.epa.gov/yellowstoneriverspill.

PIPELINE REPLACEMENT

We are working to ensure we meet the requirements of U.S. Department of
Transportation′s Corrective Action Order before we resume pipeline
operations in Billings.

In order to lessen the impact of the pipeline shutdown on the local
economy, we have also begun preliminary work for the replacement of the
pipeline. This work includes discussions on permitting requirements,
rights of ways, drilling equipment, contracting and pipeline fabrication
and transportation.

COMMUNITY OUTREACH AND CLAIMS UPDATE

ExxonMobil employees are visiting residents in the most impacted areas
of the spill to ensure residents′ needs are being met. To date, we have
visited more than 150 residents. Our goal is to answer any questions
residents may have about the claims process or spill and cleanup
activities. We will continue reaching out to residents throughout the
week.

To date we have received more than 300 calls from the community. Our
team is responding to more than 120 claims related to property,
agriculture or health, and these claims are being resolved as quickly as
possible. More than 130 calls have been from people offering volunteer
assistance. We appreciate the support of the Billings community as we
work to restore the area.

To address individual health concerns, teams of trained environmental
specialists are conducting air and water quality testing. Those who may
have been affected are encouraged to use the community information line
(1-888-382-0043).

WILDLIFE ASSESSMENT AND RECOVERY

We continue to work with International Bird Rescue, U.S. Fish and
Wildlife Service and Montana Fish, Wildlife and Parks to survey the area
for impacts to wildlife. Members of the team are surveying the affected
areas of the river for oiled wildlife. We are also inspecting the
property of landowners who have called the community or wildlife
hotlines regarding impacted wildlife on their property.

The total number of treated wildlife is four: a garter snake and a
western toad (which were treated and released), a Woodhouse′s toad
(which will be released today) and a warbler (which is being cleaned).
In addition, several oiled birds were observed and we are assessing if
any require capture or cleaning. Today, two boats are scheduled to go
out onto the slack, or shallow, water to continue to search for any
additional wildlife that may have been affected by the incident. Aerial
helicopter surveys are conducted daily to observe wildlife conditions.
