 STOCK UNIT AGREEMENT

  

	 Payment for Units 
	No payment is required for the units that you are receiving. 

  

	 Vesting—General Rules

meet fully the FY 2013 Threshold Performance Measures, as described below. 

  

	 	No units will vest after your Service (as defined below) has terminated for any reason, except as set forth in this Agreement or a Severance Agreement between you and
the Company. 

  

	 FY 2012 Performance-Based Vesting Conditions 
	Subject to any adjustment based on failure to meet fully the FY 2013 Threshold Performance Measures, the number of your units that vest will be determined on the basis of Subscription Software

	 FY 2013 Threshold Performance Measures 
	After the number of units is calculated pursuant to the table above, there may be a further adjustment to those calculated amounts based on FY 2013 Subscription Software Revenue as described in

 [****]% growth over

FY 2012 Subscription
 Software
Revenue
	 	 100% of the Performance Adjusted

Units calculated above



  

	 	Straight-line interpolation will be used for Subscription Software Revenue amounts between the increments set forth above. 


 

	 Vesting Date 
	Subject to satisfaction of the FY 2012 Performance-Based Vesting Conditions and the FY 2013 Threshold Performance Measures specified above, 100% of the units calculated pursuant to the tables
above will vest on November 15, 2013, provided that your Service is continuous until that date. 

  

	 Adjustment of Performance-Based Vesting Conditions 
	The Committee, at its sole discretion, may make appropriate adjustments in the FY 2012 Performance-Based Vesting Conditions and the FY 2013 Threshold Performance Measures in order to account for
extraordinary events, including (without limitation) acquisitions and other corporate or financial events. 

  

	 Forfeiture 
	If your Service terminates for any reason other than upon your death or Disability, then your units will be forfeited to the extent that they have not vested before the termination date, except
as set forth in a Severance Agreement between you and the Company. This means that any units that have not vested under this Agreement or a Severance Agreement will immediately be cancelled. You receive no payment for units that are forfeited.


  

	 	The Company determines when your Service terminates for this purpose. 


  
 4 









	 Leaves of Absence and Part-Time Work 
	For purposes of this grant, your Service does not terminate when you go on a military leave, a sick leave or another bona fide leave of absence, if the leave was approved by the Company
in writing and if continued crediting of Service is required by applicable law, the Company’s written leave of absence policy (as in effect for similarly situated employees) or the terms of your leave. But your Service terminates when the
approved leave ends, unless you immediately return to active work. 

  

	 	If you go on a leave of absence during a performance period under this award, the Company may reduce your award based upon the amount of time that you were on leave,
but in no event will the reduced award be smaller than the original award multiplied by the ratio between time worked and the entire performance period. Similarly, if you commence working on a part-time basis, then the Company may reduce your award
based on the percentage of time worked as compared to a full-time employee. 

  

	 Settlement of Units 
	Each unit will be settled on the first Permissible Trading Day (as defined below) that occurs on or after the day when the unit vests. However, each unit must be settled not later than the later
of (a) December 15 of the Company’s fiscal year after the fiscal year in which the unit vests or (b) March 15 of the calendar year after the calendar year in which the unit vests. 


 

	 	At the time of settlement, you will receive one share of the Company’s Common Stock for each vested unit. 


 

	 Section 409A 
	This paragraph applies only if the Company determines that you are a “specified employee,” as defined in the regulations under Section 409A of the Internal Revenue Code of 1986,
as amended (the “Code”), at the time of your “separation from service,” as defined in those regulations. If this paragraph applies, then any units that otherwise would have been settled during the first six months following your
separation from service will instead be settled during the seventh month following your separation from service, unless the Company determines that the settlement of those units is exempt from Section 409A of the Code. 


 

	 Nature of Units 
	Your units are mere bookkeeping entries. They represent only the Company’s unfunded and unsecured promise to issue shares of Common Stock (or distribute cash) on a future date. As a holder
of units, you have no rights other than the rights of a general creditor of the Company. 

  

	 No Voting Rights or Dividends 
	Your units carry neither voting rights nor rights to cash dividends. You have no rights as a stockholder of the Company unless and until your units are settled by issuing shares of the
Company’s Common Stock. 


  
 5 









	 Units Nontransferable 
	You may not sell, transfer, assign, pledge or otherwise dispose of any units. For instance, you may not use your units as security for a loan. 


 

	 Withholding Taxes 
	No stock certificates or cash will be distributed to you unless you have made arrangements, as directed by the Company, for the payment of any withholding taxes that are due as a result of the
settlement of this award. At the discretion of the Company, these arrangements may include (a) payment in cash, (b) payment from the proceeds of the sale of shares through a Company-approved broker or (c) withholding shares of Company
stock that otherwise would be issued to you when the units are settled. However, if you are a Company officer subject to Section 16 of the Securities Exchange Act of 1934, as amended, then your withholding tax obligations in connection with this
award will be satisfied pursuant to clause (c) of the preceding sentence, unless otherwise determined in advance by the Committee. The fair market value of these shares, determined as of the date when taxes otherwise would have been withheld in
cash, will be applied to the withholding taxes. 

  

	 Restrictions on Resale 
	You agree not to sell any shares at a time when applicable laws, Company policies or an agreement between the Company and its underwriters prohibit a sale. This restriction will apply as long as
your Service continues and for such period of time after the termination of your Service as the Company may specify. 

  

	 Employment at Will 
	Your award or this Agreement does not give you the right to be retained by the Company or a subsidiary of the Company in any capacity. The Company and its subsidiaries reserve the right to
terminate your Service at any time, with or without cause. 

  

	 Adjustments 
	In the event of a stock split, a stock dividend or a similar change in Company stock, the number of your units will be adjusted accordingly, as the Company may determine pursuant to the Plan.


  

	 Effect of Merger 
	If the Company is a party to a merger, consolidation or reorganization, then your units will be subject to Section 10.3 of the Plan, provided that any action taken must either
(a) preserve the exemption of your units from Section 409A of the Code or (b) comply with Section 409A of the Code. 

  

	 Applicable Law 
	This Agreement will be interpreted and enforced under the laws of the State of Delaware (without regard to its choice-of-law provisions).

	 The Plan and Prior Agreements 
	The text of the Plan is incorporated in this Agreement by reference. 

  

	 	The Plan, this Agreement and the Notice of Stock Unit Award constitute the entire understanding between you and the Company regarding this award. Any prior agreements,
commitments or negotiations concerning this grant are superseded. However, if you and the Company entered into a Severance Agreement, then that Severance Agreement is not superseded and will continue to apply as described below.


  

	 Amendments 
	This Agreement may be amended only by another written agreement between the parties. 

  

	 Interpretation of Severance Agreement 
	If you and the Company entered into a Severance Agreement, then the vesting acceleration provisions or vesting continuation provisions (as applicable) of that Severance Agreement will be applied
to this award as follows: 

  

	 	•	 	 If a Change in Control (as defined in the Severance Agreement) occurs and you become entitled to accelerated vesting under the Severance Agreement
after the Change in Control but before October 1, 2012, then 200% of the total number of your granted units will vest immediately. The FY 2012 Performance-Based Vesting Conditions and the FY 2013 Threshold Performance Measures will be
disregarded. 


  

	 	•	 	 If no Change in Control occurs but you become entitled to accelerated vesting (or continued vesting during a defined Continuation Period) under the
Severance Agreement before October 1, 2012, then, for the purpose of calculating the number of units eligible for vesting acceleration or vesting continuation under the Severance Agreement, the FY 2012 Performance-Based Vesting Conditions will
be deemed to have been met at the 100% award vesting levels defined in the Subscription Software Revenue table above. The FY 2013 Threshold Performance Measures will be disregarded. 



 

	 	•	 	 If you become entitled to accelerated vesting (or continued vesting during a defined Continuation Period) for any reason under the Severance Agreement
after September 30, 2012, but before October 1, 2013, then, for the purpose of calculating the number of units eligible for vesting acceleration or vesting continuation under the Severance Agreement, the actual percentage of the units
calculated pursuant to the Subscription Software Revenue table will be used. The FY 2013 Threshold Performance Measures will be disregarded. 



  
 7 









	 	•	 	 If you become entitled to accelerated vesting (or continued vesting during a defined Continuation Period) for any reason under the Severance Agreement
after September 30, 2013, for the purpose of calculating the number of units eligible for vesting acceleration or vesting continuation under the Severance Agreement, the actual percentage of the units calculated pursuant to the Subscription
Software Revenue table will be used, subject to any adjustment pursuant to the second table based on failure to meet fully the FY 2013 Threshold Performance Measures. 



 

	 Acceleration Upon Death or Disability 
	A number of units determined as follows will immediately vest if you die or become Disabled. 

  

	 	•	 	 If you die or become Disabled during your Service before October 1, 2012, then, for the purposes of calculating the number of units eligible for
vesting acceleration hereunder, the FY 2012 Performance-Based Vesting Conditions will be deemed to have been met at the 100% award vesting levels defined in the Subscription Software Revenue table above. The FY 2013 Threshold Performance Measures
will be disregarded. 


  

	 	•	 	 If you die or become Disabled during your Service after September 30, 2012 but before October 1, 2013, then, for purposes of calculating the number of
units eligible for vesting acceleration hereunder, the actual percentage of the units calculated pursuant to the Subscription Software Revenue table above will be used. The FY 2013 Threshold Performance Measures will be disregarded.



  

	 	•	 	 If you die or become Disabled during your Service after September 30, 2013, then, for purposes of calculating the number of units eligible for vesting
acceleration hereunder, the actual percentage of the units calculated pursuant to the Subscription Software Revenue table above will be used, subject to any adjustment pursuant to the failure to meet fully the FY 2013 Threshold Performance Measures.
