and conditions set forth in this notice (“Award Notice”). 
 1. Award. Subject to the terms and conditions set forth

Notice, the Award shall vest and become non-forfeitable on the later of (i) the third (3rd) anniversary of the Grant Date (such date, the “Scheduled Vesting Date”, and such
three-year period from the Grant Date, the “Applicable Period”) and (ii) the date that the Committee certifies the performance results as described on Schedule I attached hereto (the “Performance Vesting
Date”), provided that the Grantee remains in continuous service with the Company or any of its Subsidiaries on the Scheduled Vesting Date or the Performance Vesting Date, as applicable. The Grantee shall be entitled to receive that number
of RSUs (if any) equal to (x) the Performance Leverage Factor (as defined on Schedule I) multiplied by (y) the Target RSUs (as defined on Schedule I). 

(b) Except as otherwise provided in this Section 2, in the event that the Grantee’s continuous service is terminated by the Company or by
the Grantee for any reason (including for death or Disability), the Grantee shall forfeit the unvested Award as of the Grantee’s termination date. 

(c) In the event that the Grantee’s continuous service is terminated by the Company due to the Grantee’s death or Disability (i)
after the one-year anniversary of the Grant Date but before the date that is six (6) months prior to the expiration of the Performance Period (as defined on Schedule I), the unvested Award shall immediately vest assuming that Target
Achievement Level (as defined on Schedule I) has been achieved, prorated to reflect the number of months employed during the Applicable Period; or (ii) after the date that is six (6) months prior to the expiration of the Performance Period,
the unvested Award shall vest on the Performance Vesting Date based on the Performance Leverage Factor achieved for the full Performance Period, prorated to reflect the number of months employed during the Applicable Period. 







 (d) Except as otherwise provided in Section 2(e), in the event that the Grantee’s continuous
service is terminated by the Company without Cause after the one-year anniversary of the Grant Date but prior to either the Scheduled Vesting Date or the Performance Vesting Date, the unvested Award shall vest on the Performance Vesting Date based
on the Performance Leverage Factor achieved for the full Performance Period, prorated to reflect the number of months the Grantee was employed during the Applicable Period. 

(e) Immediately prior to a Change in Control, the Target RSUs shall convert into service-based RSUs and the Award shall vest on the Scheduled
Vesting Date (without regard to achievement of any of the performance metrics set forth on Schedule I), provided that the Grantee remains in continuous service with the Company or any of its Subsidiaries on the Scheduled Vesting Date.
Notwithstanding any provision herein to the contrary, (i) if the Committee has made a provision for the substitution, assumption, exchange or other continuation of the Award in connection with a Change in Control, then in the event that the
Grantee’s continuous service is terminated (A) by the Company due to death or Disability following the occurrence of the Change in Control, then Section 2(c) shall not apply and the unvested Award shall immediately fully vest, but prorated to
reflect the number of months employed during the Applicable Period, or (B) by the Company other than for Cause, and other than due to death or Disability, within one (1) year following the occurrence of the Change in Control, the unvested Award
shall become immediately fully vested; or (ii) if the Committee has not made a provision for the substitution, assumption, exchange or other continuation of the Award in connection with a Change in Control, then the unvested Award shall become
fully vested immediately prior to the Change in Control. 
 (f) Within 30 days following the Scheduled Vesting Date or the Performance
Vesting Date, as applicable (or, if applicable, an earlier vesting date pursuant to Section 2(c)(i) or Section 2(e) above) (such relevant date, the “Vesting Date”), the Company shall settle the Award and shall therefore, subject to
any required tax withholding and the execution of any required documentation, (i) issue and deliver to the Grantee one share of Common Stock for each earned and vested RSU as determined hereunder (the “RSU Shares”) (and, upon such
settlement, the RSUs shall cease to be credited to the account) and (ii) enter the Grantee’s name as a shareholder of record with respect to the RSU Shares on the books of the Company. Alternatively, the Committee may, in its sole discretion,
elect to pay cash or part cash and part RSU Shares in lieu of settling the vested RSUs solely in RSU Shares. If a cash payment is made in lieu of delivering RSU Shares, the amount of such payment shall be equal to the Fair Market Value of the RSU
Shares (determined as of the Vesting Date) less an amount equal to any federal, state, local and non-U.S. income and employment taxes required to be withheld. 

(g) Simultaneously with the settlement and delivery of RSU Shares as contemplated by Section 2(f), the Grantee shall be entitled to receive an
additional amount (the “Dividend Equivalent Amount”) equal to the product of (i) the cash amount of each per share dividend that was paid by the Company on shares of its Common Stock (“Shares”) on any date that the
Grantee’s RSUs remained outstanding hereunder (or, in the case of a dividend payable in Shares or other property, the per Share equivalent cash value of such dividend as determined in good faith by the Committee) and (ii) the number of RSU
Shares so delivered (or, if the RSUs are not settled exclusively in Shares, the number of RSU Shares that would have been delivered had they been settled exclusively in Shares). The Dividend Equivalent Amount shall be payable in cash

or, at the discretion of the Committee, in Shares with an equivalent Fair Market Value on the date of payment. The Company shall establish a bookkeeping methodology to account for the
Dividend Equivalent Amount. The Dividend Equivalent Amount shall not bear interest. 
 (h) The Company shall have the right to require
prior to the issuance or delivery of any Shares or the payment of any cash pursuant to the Award, payment by the Grantee of any federal, state, local or other taxes that may be required to be withheld or paid in connection with the Award. At the
sole discretion of the Committee, the Grantee may satisfy such withholding obligation (1) by allowing the Company to withhold whole Shares that would otherwise be delivered to the Grantee, having an aggregate Fair Market Value, determined as of the
date the obligation to withhold or pay, equal to the minimum withholding taxes required in connection with the Award or by allowing the Company to withhold an amount of cash that would otherwise be payable to the Grantee, in the amount necessary to
satisfy any such obligation; (2) by paying such obligation in cash; (3) by delivering Shares or (4) by any combination of the foregoing (1) through (3). 

3. Non-Transferability. The Award is subject to the restrictions on transferability set forth in Section 15(b) of the Plan. In
addition, with respect to any RSU Shares delivered upon settlement of the RSUs, the Grantee agrees to comply with any written holding requirement policy adopted by the Company for employees.

Shares on the books of the Company. 
 5. Adjustments. The Award is subject to adjustment pursuant to Sections 12 and 13 of the Plan.

have been registered under the Securities Act or, upon request by the Company, the Company first shall have been furnished with an opinion of legal counsel, reasonably satisfactory to the Company, to the effect that such sale or transfer is exempt
from the registration requirements of the Securities Act. 
 7. Notice. Every notice or other communication relating to this Award Notice
shall be in writing, and shall be mailed to or delivered to the party for whom it is intended at such address as may from time to time be designated by it in a notice mailed or delivered to the other party as herein provided; provided,

Company to the Grantee may be given to the Grantee personally or may be mailed to the Grantee’s address as recorded in the records of the Company or any Subsidiary.

 [SCHEDULE I 

Performance Leverage Factor 

Except as may otherwise be provided herein, the RSUs shall vest as to the performance conditions based on the achievement of specified levels of the
Performance Goals for the Performance Period, as set forth herein. 
 Target RSUs =
[                ] shares of Common Stock. 
  

	(i)	Billings Metric  

 The Performance Leverage Factor will be weighted one-half (1/2)
based on the achievement of cumulative Billings (as defined below) for the Company’s [        ], [        ] and [        ]
fiscal years (such three-fiscal-year period, the “Performance Period”), as follows: 
  

													
	 Achievement Level
	  	Billings Goal	 	  	Billings
Achievement
Percentage	 	 	Billings
Payout
Percentage1	 
	 Maximum
	  	$	[            	] 	  	 	[        	]% 	 	 	[        	]% 
	 Target
	  	$	[            	] 	  	 	[        	]% 	 	 	[        	]% 
	 Threshold
	  	$	[            	] 	  	 	[        	]% 	 	 	[        	]% 

 If the Billings Achievement Percentage for the Performance Period is greater than Threshold Achievement Level
and less than Target Achievement Level, or greater than Target Achievement Level and less than Maximum Achievement Level, then the Billings Achievement Percentage (and, in turn, the Billings Payout Percentage) shall be determined based on linear
interpolation between the applicable Achievement Levels. If Billings Achievement Percentage for the Performance Period is equal to or greater than the Maximum Achievement Level, then the Billings Payout Percentage shall be capped at
[        ]%. 
 For the avoidance of doubt, if the Billings Achievement Percentage achieved for the
Performance Period is less than Threshold Achievement Level, then the Billings Achievement Percentage shall be zero. 

“Billings” is measured by Net Sales in accordance with accounting principles generally accepted in the United States adjusted
for the change in deferred revenue on the balance sheet during the period and for the impact of material acquisitions and divestitures. 
  

	(ii)	Total Shareholder Return Metric  

 The Performance Leverage Factor will be
weighted one-half (1/2) based on the Total Shareholder Return (“TSR”) (as defined below) for the Company as compared and ranked 







 
against the TSR performance of each of the companies in the Peer Group (as defined below) for the Performance Period (the “TSR Percentile Ranking”), as follows: 

 

									
	 Achievement Level
	  	TSR Percentile
Ranking	 	  	TSR
Payout
Percentage	 
	 Maximum
	  	 	[            	] 	  	 	[        	]% 
	 Stretch
	  	 	[            	] 	  	 	[        	]% 
	 Target
	  	 	[            	] 	  	 	[        	]% 
	 Threshold
	  	 	[            	] 	  	 	[        	]% 

 If the TSR Percentile Ranking achieved for the Performance Period is greater than Threshold Achievement Level
and less than Target Achievement Level, or greater than Target Achievement Level and less than Stretch Achievement Level, or greater than Stretch Achievement Level and less than Maximum Achievement Level, then the TSR Payout Percentage shall be
determined based on linear interpolation between the applicable Achievement Levels. If the TSR Percentile Ranking for the Performance Period is equal to or greater than the Maximum Achievement Level, then the TSR Payout Percentage shall be
capped at [        ]%. 
 Notwithstanding the foregoing, if the Company’s TSR for the
Performance Period is negative, then the TSR Payout Percentage shall be capped at [        ]%. For the avoidance of doubt, if the TSR Percentile Ranking achieved for the Performance Period is less than
Threshold Achievement Level, then the TSR Payout Percentage shall be zero. 
 “Company Average Share Price” shall mean the
average closing price of the Common Stock (as reported on the principal stock exchange or automated quotation system on which the Common Stock is traded or listed) for the twenty (20) consecutive market trading days ending on and including the date
of determination (adjusted, as applicable, for stock splits, reorganizations, recapitalizations, or similar corporate transactions during such period). 

“Company Share Price Appreciation” shall mean the result (which may be negative) obtained by subtracting the Company Average
Share Price as of the last day of the Performance Period from the Company Average Share Price on the day prior to the first day of the Performance Period. 

“Peer Group” shall mean the companies included in the Russell 2000 Small Cap Market Index on the first day of the Performance
Period; provided however, that, any company included in the Russell 2000 Small Cap Market Index for less than the entire Performance Period either due to an acquisition, a going private transaction, or a merger where the surviving entity does not
remain in the Peer Group, shall be excluded from and not considered part of the Peer Group. 
 “Peer Group Company Average Share
Price” shall mean, with respect to each company in the Peer Group, the average closing price of the common stock of the applicable Peer Group company (as reported on the principal stock exchange or automated quotation system on which such
common stock is traded or listed) for the twenty (20) consecutive market trading days 







 
ending on and including the date of determination (adjusted, as applicable, for stock splits, reorganizations, recapitalizations, or similar corporate transactions during such period). 

“Peer Group Company Share Price Appreciation” shall mean the result (which may be negative) obtained by subtracting the Peer
Group Company Average Share Price as of the last day of the Performance Period from the Peer Group Company Average Share Price on the day prior to the first day of the Performance Period. 

“Total Shareholder Return” shall mean: 

(1) as applied to the Company, the quotient (expressed as a percentage return, which may be negative) obtained by dividing (A) by (B), where:

 (A) is the sum of: 
 (i)
the Company Share Price Appreciation, plus 
 (ii) dividends and distributions made or declared during the Performance Period (it shall be
assumed that such dividends or distributions are immediately reinvested in Common Stock as of the dividend payment date by dividing such dividends or distributions (or the fair market value of any non-cash dividends or distributions as determined by
the Committee) by the closing share price for the Common Stock (as reported on the principal stock exchange or automated quotation system on which the Common Stock is traded or listed) as of the dividend payment date, and then converted back to a
cash amount by dividing by the closing share price of the Common Stock (as reported on the principal stock exchange or automated quotation system on which the Common Stock is traded or listed) as of the last day of the Performance Period); and 

(B) is the Company Average Share Price as of day immediately prior to the first day of the Performance Period; and 

(2) as applied to each company in the Peer Group, the quotient (expressed as a percentage return, which may be negative) obtained by dividing
(A) by (B), where: 
 (A) is the sum of: 

(i) the applicable Peer Group Company Share Price Appreciation, plus 

(ii) dividends and distributions made or declared during the Performance Period (it shall be assumed that such dividends or distributions are
immediately reinvested in the common stock of the relevant Peer Group company as of the dividend payment date by dividing such dividends or distributions (or the fair market value of any non-cash dividends or distributions as determined by the
Committee) by the closing share price for such stock (as reported on the principal stock exchange or automated quotation system on which such stock is traded or listed) as of the dividend payment date, and then converted back to a cash amount by
dividing by the closing share price of the relevant stock (as reported on the principal stock exchange or automated quotation system on which such stock is traded or listed) as of the last day of the Performance Period); and 







 (B) is the applicable Peer Group Company Average Share Price as of day immediately prior to the
first day of the Performance Period; and 
 Performance Leverage Factor Calculation 

The Performance Leverage Factor (expressed as a percentage) shall be determined as the result of the sum of: 

(Billings Payout Percentage * 50%) + (TSR Payout Percentage * 50%)]2
