ARTICLE IV

EXERCISE OF AWARD

4.1 Exercise Proceeds.

(a) Not later than ten (10) days following each Exercise Date, the Company shall mail or otherwise deliver to the Employee an amount in respect of
each Stock Appreciation Right automatically exercised on such Exercise Date equal to Cumulative Annual VWAP Increase (as defined below) on such Exercise Date, as provided in Section 4.1(e) below (the SAR Payment Amount).

(b) For purposes of this Agreement, Annual VWAP means an amount equal to (i) the aggregate sum of the product of (A) the greater
of the Base Price or the closing price of the Companys Common Stock reported on NASDAQ for each trading day during the twelve (12) month period immediately preceding the Exercise Date (the Measurement Period) multiplied by
(B) the NASDAQ reported trading volume for the Companys Common Stock for each trading day during the Measurement Period, which aggregate sum is then divided by (ii) the total aggregate NASDAQ reported trading volume during the
Measurement Period.

(c) For purposes of this Agreement, Annual Increase (if any) for any given annual Measurement Period means
the excess, if any, of the Annual VWAP for that Measurement Period over the Base Price per Stock Appreciation Right set forth in the Grant Notice, subject to the following limitation: for any given annual Measurement Period, in no event may the
Annual Increase exceed Thirty Dollars ($30) per Stock Appreciation Right, even if the excess of the Annual VWAP for that Measurement Period over the Base Price per Stock Appreciation Right is greater than Thirty Dollars ($30). The foregoing
limitation of Thirty Dollars ($30) per Stock Appreciation per year applies only with regard to the Annual Increase, and not to the Cumulative Annual VWAP Increase (as defined below).

(d) For purposes of this Agreement, Cumulative Annual VWAP Increase (if any) on any given Exercise Date means the sum of (i) the Annual
Increase (if any) for the twelve (12) month period immediately preceding such Exercise Date and (ii) each of the Annual Increase(s) (if any) for each of the annual Measurement Period(s) (if any) preceding the twelve (12) month period
covered by clause (i).

(e) The Annual VWAP, Annual Increase (if any) and Cumulative Annual VWAP Increase (if any) will be calculated as
follows in relation to each of the four (4) annual Measurement Periods in accordance with the Exercise Schedule set forth in the Grant Notice:

(i)On the first (1st) annual Exercise Date, the Annual VWAP and the Annual Increase (if any)
for the first annual Measurement Period will be calculated. The SAR Payment Amount (if any) for the first annual Measurement Period will equal the Annual Increase (if any) for the first annual Measurement Period.

(ii)On the second (2nd) annual Exercise Date, the Annual VWAP and the Annual Increase (if any) for the second annual Measurement Period will be calculated, and the Cumulative Annual VWAP Increase (if any) will equal the sum of (A) the Annual
Increase (if any) for the first annual Measurement Period and (B) the Annual Increase (if any) for the second annual Measurement Period. The SAR Payment Amount (if any) for the second annual Measurement Period will equal the Cumulative Annual
VWAP Increase (if any) as so calculated over the first two Measurement Periods.

(iii)On the third (3rd) annual Exercise Date, the Annual VWAP and the Annual Increase (if any) for the third annual Measurement Period will be
calculated, and the Cumulative Annual VWAP Increase (if any) will equal the sum of (A) the Annual Increase (if any) for the first annual Measurement Period, (B) the Annual Increase (if any) for the second annual Measurement Period and
(C) the Annual Increase (if any) for the third annual Measurement Period. The SAR Payment Amount (if any) for the third annual Measurement Period will equal the Cumulative Annual VWAP Increase (if any) as so calculated over the first three
Measurement Periods.

---

(iv)On the fourth (4th) annual Exercise Date, the Annual VWAP and the Annual Increase (if any) for the fourth annual Measurement Period will be calculated, and the Cumulative
Annual VWAP Increase (if any) will equal the sum of (A) the Annual Increase (if any) for the first annual Measurement Period, (B) the Annual Increase (if any) for the second annual Measurement Period, (C) the Annual Increase (if any)
for the third annual Measurement Period and (D) the Annual Increase (if any) for the fourth annual Measurement Period. The SAR Payment Amount (if any) for the fourth annual Measurement Period will equal the Cumulative Annual VWAP Increase (if
any) as so calculated over the four Measurement Periods.

(v)By way of illustration only, if the Annual Increase for the first
Measurement Period equaled $10, the Annual Increase for the second Measurement Period equaled $15, the Annual Increase for the third Measurement Period equaled $33 (subject however to the $30 cap provided in Section 4.1(c) above), and the
Annual Increase for the fourth Measurement Period equaled $0, then the SAR Payment Amounts would be as follows: for the first Exercise Date, the SAR Payment Amount would equal $10; for the second Exercise Date, the Cumulative Annual VWAP Increase
and the SAR Payment Amount would equal $25, or $10 plus $15; for the third Exercise Date, the Cumulative Annual VWAP Increase and the SAR Payment Amount would equal $55, or $10 plus $15 plus $30; and for the fourth Exercise Date, the Cumulative
Annual VWAP Increase and the SAR Payment Amount would equal $55, or $10 plus $15 plus $30 plus $0.

(f) The SAR Payment Amount (if any)
shall be paid by the Company in whole shares of the Companys Common Stock, with fractional amounts payable in cash; provided, however, that at the Companys sole discretion all or a portion of the SAR Payment Amount may be paid in cash or
other property.

(g) Any amount payable pursuant to this Section 4.1 shall be subject to the Companys collection of all
applicable federal, state and local income and employment taxes required to be withheld therefrom.

4.2 No Rights of Ownership. At
no time shall the Employee have any rights of ownership with respect to any Company Common Stock by reason of the grant or exercise of this Award.

receipt or, in the case of notices delivered by the Company to the Employee, five (5) days after deposit in the United States mail, postage prepaid, addressed to the Employee at the address specified on the first page of this Agreement or at
such other address as the Employee may hereafter designate by written notice to the Company.

consent or approval of any governmental regulatory authority, is necessary or desirable as a condition to the issuance of shares of Common Stock to the Employee (or his or her estate), such issuance will not occur unless and until such listing,
registration, qualification, consent or approval will have been effected or obtained free of any conditions not acceptable to the Company. The Company will make all reasonable efforts to meet the requirements of any such state or federal law or
securities exchange and to obtain any such consent or approval of any such governmental authority.
