AMENDMENT TO THE
SEVERANCE AND CHANGE IN CONTROL AGREEMENT

WHEREAS, KBR, Inc. (“KBR”) desires to amend the Severance and Change in Control
Agreement (the “Agreement”) entered into by and between Executive, Executive’s
employer, and KBR to reflect the most prevalent practice of KBR’s industry peers
and to address the difficulty of valuing KBR’s long-term cash performance awards
prior to the end of the performance period due to the new job income sold
performance metric;

NOW, THEREFORE, effective as of August 5, 2015, the Agreement shall be amended
as follows:

Paragraph (v) of Section 4.2 of the Agreement shall be deleted in its entirety
and the following shall be substituted therefor:

“(v) all performance award units granted prior to January 1, 2015, other than
those that are covered under Company’s annual cash incentive plan, shall be
prorated to the date of termination and paid on actual performance at the end of
the performance period, but not later than March 15th following the end of the
performance period, and all performance award units granted on or after to
January 1, 2015, other than those that are covered under Company’s annual cash
incentive plan, shall become fully vested and paid at target performance as soon
as administratively feasible following Executive’s termination of employment
with Company, but not later than March 15th following the year in which
Executive terminated employment with Company;”

IN WITNESS WHEREOF, this instrument has been executed on this _____ day of
_______________ 2015, effective as provided above.
