Exhibit 10.4

AMENDMENT TO
RESTRICTED STOCK UNIT AGREEMENT

UNDER THE CITRIX SYSTEMS, INC.
AMENDED AND RESTATED 2014 EQUITY INCENTIVE PLAN
Reference is hereby made to the Restricted Stock Unit Agreement with respect to
Awards with an Award Date of August 1, 2017 and a performance period of July 10,
2017 through December 31, 2019 (the “Award Agreement”). Capitalized terms used
herein and not otherwise defined shall have the meanings set forth in the Award
Agreement.
A.The Schedule to the Restricted Stock Unit Agreement is deleted in its entirety
and replaced with the following:

SCHEDULE TO RESTRICTED STOCK UNIT AGREEMENT
The number of Restricted Stock Units vested as a percentage of the Target Award
shall be determined based on Subscription Bookings as a % of Product Bookings
(as defined below) at the end of the Performance Period in accordance with the
following table:
Subscription Bookings as a % of Product Bookings
Percentage of Target Award Vested
Subscription Bookings as a % of Product Bookings (threshold)
50%
Subscription Bookings as a % of Product Bookings (target)
100%
Subscription Bookings as a % of Product Bookings (maximum)
200%

Restricted Stock Units vested will be based on straight-line interpolation
between the %s above. There will be no Restricted Stock Units vested if
Subscription Bookings as a % of Product Bookings is less than the threshold.

“Subscription Bookings as a % of Product Bookings” means the Company’s total
term, cloud (SaaS), hybrid-cloud and Citrix Service Provider product
subscription bookings or any other product bookings from subscription offerings,
including subscription renewals, expansions, extensions, upgrades, updates,
initial and add-on or multiple year terms of any of the foregoing, but excluding
transition and trade-up bookings, over the Company’s total product bookings
excluding transition and trade-up bookings, in each case excluding ShareFile SMB
bookings, measured as of the last fiscal year of the Performance Period (fiscal
year 2019) on a Total Contract Value (TCV) basis, and expressed as a percentage
rounded to two decimal places. For purposes of this Agreement only, “bookings”
means a clean customer order as defined under the Company’s practices.

B.
The following definition is added to Section 2(c) of the Award Agreement:

“Disability” shall have the meaning set forth in any employment, executive or
similar agreement between the Company and Awardee or, if none, means Awardee’s
termination of employment with the Company or any of its Affiliates after
becoming eligible to receive benefits under the Company’s or such Affiliate’s
then current long-term disability plan applicable to Awardee.
C.
The following clause (c) is added to Section 4 of the Award Agreement:

“(c)    Notwithstanding anything to the contrary herein, the provisions relating
to the treatment of performance-based Restricted Stock Units, including any
rights to acceleration, that may be set forth in an employment or executive
agreement between the Company and Awardee shall apply to this Award to the
extent applicable; provided that if a Change in Control (as defined in such
employment or executive agreement) occurs during the term of such employment or
executive agreement but prior to the last fiscal year of the Performance Period,
then actual performance shall be measured based on, and Awardee shall be deemed
to have earned, the CIC Percentage (as defined below) of the Target Award as of
the Change in Control; provided further that, subject to any rights to
acceleration set forth in such employment or

--------------------------------------------------------------------------------

executive agreement, the shares deemed earned shall remain subject to time-based
cliff vesting at the end of the remaining Performance Period. For purposes of
this Section 4(c), “CIC Percentage” shall mean (i) 50% if Subscription Bookings
as a % of Product Bookings as of the Change in Control (measured, for purposes
of this clause (i) and the following clauses (ii) and (iii), from January 1,
2018 through the end of the calendar month immediately preceding the Change in
Control) is 20%, (ii) 100% if Subscription Bookings as a % of Product Bookings
as of the Change in Control is 30%, and (iii) 200% if Subscription Bookings as a
% of Product Bookings as of the Change in Control is 40% (with straight-line
interpolation between the %s above, and no Restricted Stock Units deemed earned
if Subscription Bookings as a % of Product Bookings as of the Change in Control
is less than 20%).”
D.The foregoing amendments shall be effective as of March 29, 2018. Except as
amended hereby, the Award Agreement remains in full force and effect.

E.For the avoidance of doubt, Awardee acknowledges and agrees that the Award
Agreement, as amended hereby, satisfies the obligations of the Company under
Section 2(c) of Awardee’s Employment Agreement with the Company, dated as of
July 10, 2017, with respect to the grant of performance-based restricted stock
units to Awardee based on “New Cloud Bookings” as referenced therein.

By electronically accepting this Amendment to the Award Agreement and
participating in the Plan, Awardee agrees to be bound by the terms and
conditions in the Plan and the Award Agreement (including the Appendix), as
amended hereby. If Awardee has not electronically accepted this Amendment to the
Award Agreement by September 29, 2018 on Fidelity.com’s website, then this
Amendment shall automatically be deemed accepted, and Awardee shall be bound by
the terms and conditions in the Plan and the Award Agreement (including the
Appendix), as amended hereby.
