Exhibit 10.18  Caliper
Performance Bonus Plan  This
Performance Bonus Plan (the Bonus Plan) for eligible employees of Caliper
Life Sciences, Inc. (Caliper or the Company) covers the period from January 1
to December 31 of each calendar year. 
This Bonus Plan contains the entire agreement on this subject between
the Company and those employees who have been notified in writing by the
Company of their eligibility to participate in this Bonus Plan, and supersedes
all prior performance bonus compensation programs of the Company and all other
previous oral or written statements to any employee of the Company regarding
any previous performance bonus plan.  The
Company reserves the right to modify any of the provisions of this Bonus Plan
at any time with or without written notice. 
This Bonus Plan may be modified only in a writing signed by either the
Chief Executive Officer of the Company or the Companys Senior Vice President
of Human Resources.  Eligibility
for participation in this Bonus Plan is based upon certain criteria including
but not limited to job function, level and/or title as defined from time to
time by the Company in its sole discretion. 
Target bonus amounts under this Bonus Plan will vary based on the Companys
criteria and an eligible employees job function, level and/or title.  Only those employees of the Company who are
notified in writing by the Company of their eligibility to participate in this
Bonus Plan will be eligible to receive performance bonuses under this Bonus
Plan, which will be determined in accordance with an employees designated
target bonus amount and the other terms and conditions of this Bonus Plan.  The Chief Executive Officer and employees on
commission or sales incentive plans are not eligible to participate in this Bonus
Plan.  No bonus amounts are guaranteed
and all bonuses must be earned in accordance with the terms of this Bonus
Plan.  Whether and how much of a
performance bonus has been earned, at any bonus level, and determination of
whether an employee is in good standing, is in the sole discretion of the
Company.  No
bonus is considered earned under this Bonus Plan until the time that such bonus
is paid under the terms of this Bonus Plan. Thus, in the event that a Bonus
Plan participants employment has been terminated (either by the Company or by
the employee), the participant will not be entitled to any bonus that has not
been paid prior to the termination date.  Performance
bonuses under this Bonus Plan will be paid in the following calendar year after
individual performance reviews for the previous year have been completed, and
after the Board of Directors has determined the degree to which Caliper has
attained its corporate goals for the previous year.  Historically, performance bonuses have been
paid prior to the end of April, but the date may vary each year and is subject
to the Companys discretion.  Employees
who are hired during the year are entitled to receive a prorated performance
bonus based on their actual time of service during the year.  An
employees performance bonus will be based on (i) the employees
individual performance assessment (as determined in connection with the
employees annual performance review by his or her manager) and (ii) the
Board of Directors assessment of the degree to which Caliper has attained its
corporate goals for the year.  An individual employees performance objectives will
be set by the employees supervisor at the beginning of the bonus period.  It is the responsibility of both the employee
and his or her supervisor to ensure such written objectives are set.  No performance bonus will be paid unless the
employee attains 70% or more of his or her overall performance objectives.
Where numerous performance objectives are listed but no weighting of relative
importance of performance objectives is provided, the Company will determine in
its sole discretion how much weighting each performance objective should be
provided.  TheCompany, in its sole discretion, will
determine whether an employee attained a percentage of any one


performance
objective and will consider any such pro rata attainment when assessing the
employees attainment of overall performance objectives.  Calipers
Board of Directors will determine the objectives to be met by the Company in
each calendar year, as well as the degree to which the corporate goals for such
year have been attained.  The
performance bonus calculation is as follows:  Base
Earnings  X  Target Bonus Percentage = Bonus Opportunity  Bonus
Opportunity  X  Individual Rating  X  Corporate Rating=
Bonus Earned  Nothing
in this Bonus Plan is intended to alter the at-will nature of each employees
employment, that is, an employees right or the Companys right to terminate an
employees employment at will, at any time, with or without cause.  Revised by the Companys Board of Directors as of February 12,
2010.
