Acacia and You desire to amend the Original Agreement as set forth below.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants set
forth herein, Acacia and You, intending to be legally bound, hereby agree as
follows:
 
 
1.
Section 3.6 of the Original Agreement is hereby amended and restated to read in
its entirety as follows:

”Travel Expenses.  Acacia shall reimburse You for all reasonable travel,
lodging, and meal expenses incurred on behalf of Acacia.  All expenses shall be
supported by appropriate documentation and reimbursed in accordance with
Acacia’s policies and procedures. Any amounts payable under this Section 3.6
shall be made in accordance with Treasury Regulation Section 1.409A-3(i)(1)(iv)
and shall be paid on or before the last day of Your taxable year following the
taxable year in which You incur such expenses.  The amounts provided under this
Section 3.6 during any taxable year will not affect such amounts provided in any
other taxable year, and Your right to reimbursement for such amounts shall not
be subject to liquidation or exchange for any other benefit.”
 
 
2.
The Addendum is hereby superseded and Section 3.7 of the Original Agreement is
hereby amended and restated to read in its entirety as follows:

“Discretionary Annual Bonus.  At the end of each calendar year, You shall be
eligible for a discretionary bonus equal in value of up to Thirty percent (30%)
of your annual salary.  Such bonus shall be at the sole discretion of the
Compensation Committee of Acacia Research Corporation, and shall be based upon
personal performance, overall company performance, and any other factors that
the Compensation Committee elects to consider.  This bonus is solely within the
discretion of the Compensation Committee, which may elect to pay You no bonus in
any given year or years.  The Compensation Committee may increase the amount of
the discretionary bonus, but has no obligation to do so.  In order to be
eligible for the discretionary annual bonus, this Agreement must be in full
force and effect at the time of the payment of such bonus.  Such discretionary
annual bonus shall be evaluated and paid (if applicable) no later than December
31 of the calendar year following the calendar year to which such bonus
relates.  The discretionary annual bonus shall be subject to all appropriate
federal and state withholding taxes in accordance with the normal payroll

similarly situated employees of Acacia.  This provision does not alter Acacia's
right to modify or eliminate any employee benefit and does not guarantee the
continuation of any kind or level of benefits.  All such benefits shall cease
upon the termination of your employment under this Agreement.  Acacia shall
reimburse You for any reasonable work related expenses, in accordance with
Acacia’s reimbursement policies and procedures. Any amounts payable under this
Section 3.8 shall be made in accordance with Treasury Regulation Section
