|Vesting Schedule:                  |  | The Shares shall vest in a series of installments over the Participants continued Service as follows: (i) twenty-five percent (25%) of the Shares shall vest upon the Participants
completion of one year of Service measured from the Award Date and (ii) the balance of the Shares shall vest in a series of twelve (12) successive equal quarterly installments upon the Participants completion of each successive three (3)-month
period of Service over the thirty-six (36) month period measured from the first one-year anniversary of the Award Date. However, the Shares may be subject to accelerated vesting in accordance with the provisions of Paragraph 5 of this Agreement.



---

2. Limited Transferability. Prior to the actual issuance of the Shares which vest
hereunder, the Participant may not transfer any interest in the Award or the underlying Shares, except to the limited extent otherwise provided in this Paragraph 2. Any Shares which vest hereunder but which otherwise remain unissued at the time of
the Participants death may be transferred pursuant to the provisions of the Participants will or the laws of inheritance or to the Participants designated beneficiary or beneficiaries of this Award. The Participant may also direct
the Corporation to issue the stock certificates for any Shares which in fact vest and become issuable under the Award during his or her lifetime to one or more designated Family Members or a trust established for the Participant and/or his or her
Family Members. The Participant may make such a beneficiary designation or certificate directive at any time by filing the appropriate form with the Plan Administrator or its designee.

3. Cessation of Service. Should the Participant cease Service for any reason prior to vesting in one or more Shares subject to this Award,
then the Award will be immediately cancelled with respect to those unvested Shares, and the number of Restricted Stock Units will be reduced accordingly. The Participant shall thereupon cease to have any right or entitlement to receive any Shares
under those cancelled units.

4. Stockholder Rights and Dividend Equivalents

(a) The holder of this Award shall not have any stockholder rights, including voting or dividend rights, with respect to the Shares subject to the Award
until the Participant becomes the record holder of those Shares following their actual issuance upon the Corporations collection of the applicable Withholding Taxes.

(b) Notwithstanding the foregoing, should any dividend or other distribution payable other than in shares of Common Stock, whether regular or
extraordinary, be declared and paid on the outstanding Common Stock while one or more Shares remain subject to this Award (i.e., those Shares are not otherwise issued and outstanding for purposes of entitlement to the dividend or distribution), then
a special book account shall be established for the Participant and credited with a phantom dividend equivalent to the actual dividend or distribution which would have been paid on those Shares had they been issued and outstanding and entitled to
that dividend or distribution. As the Shares subsequently vest hereunder, the phantom dividend equivalents credited to those Shares in the book account shall be distributed to the Participant (in cash or such other form as the Plan Administrator may
deem appropriate in its sole discretion) concurrently with the issuance of the vested Shares to which those phantom dividend equivalents relate. However, each such distribution shall be subject to the Corporations collection of the Withholding
Taxes applicable to that distribution.

5. Change in Control.

(a) Any Restricted Stock Units subject to this Award at the time of a Change in Control may be assumed by the successor entity or otherwise continued in
full force and effect or may be replaced with a cash retention program of the successor entity which preserves the Fair Market Value of the unvested shares of Common Stock subject to the Award at the time of the Change in Control and provides for
subsequent payout of that value in



2



---

accordance with the vesting schedule applicable to the Award. In the event of such assumption or continuation of the Award or such replacement of the Award
with a cash retention program, no accelerated vesting of the Restricted Stock Units shall occur at the time of the Change in Control.

(b)
In the event the Award is assumed or otherwise continued in effect, the Restricted Stock Units subject to the Award shall be adjusted immediately after the consummation of the Change in Control so as to apply to the number and class of securities
into which the Shares subject to those units immediately prior to the Change in Control would have been converted in consummation of that Change in Control had those Shares actually been issued and outstanding at that time. To the extent the actual
holders of the outstanding Common Stock receive cash consideration for their Common Stock in consummation of the Change in Control, the successor corporation (or parent entity) may, in connection with the assumption or continuation of the Restricted
Stock Units subject to the Award at that time, substitute one or more shares of its own common stock with a fair market value equivalent to the cash consideration paid per share of Common Stock in the Change in Control transaction, provided such
common stock is readily tradable on an established U.S. securities exchange or market.

(c) If the Restricted Stock Units subject to this
Award at the time of the Change in Control are not assumed or otherwise continued in effect or replaced with a cash retention program in accordance with Paragraph 5(a), then those units will vest immediately prior to the closing of the Change in
Control. The Shares subject to those vested units will be issued immediately upon such vesting (or otherwise converted into the right to receive the same consideration per share of Common Stock payable to the other shareholders of the Corporation in
consummation of that Change in Control), subject to the Corporations collection of the applicable Withholding Taxes pursuant to the provisions of Paragraph 7.

(d) This Agreement shall not in any way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell
or transfer all or any part of its business or assets.

6. Adjustment in Shares. Should any change be made to the Common
Stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporations receipt of consideration or should any
spin-off of one or more Subsidiaries result in a substantial reduction in the Fair Market Value per share of the outstanding Common Stock, appropriate adjustments shall be made to the total number and/or class of securities issuable pursuant to this
Award in order to reflect such change and thereby preclude a dilution or enlargement of benefits hereunder.

7. Issuance of Shares of
Common Stock.

(a) On each date on which one or more Shares vest in accordance with the provisions of this Agreement or within
thirty (30) days following such vesting date, the Corporation shall issue to or on behalf of the Participant a certificate (which may be in electronic form) for the shares of Common Stock which vest on that date under the Award and shall



3



---

concurrently distribute to the Participant any phantom dividend equivalents with respect to those Shares, subject in each instance to the Corporations
collection of the applicable Withholding Taxes. In no event, however, shall such issuance occur later than the later of (i) the end of the calendar year in which the applicable vesting date occurs or (ii) the fifteenth
(15th) day of the third (3rd) calendar month following such vesting date, with the applicable Withholding Taxes to be collected on or before such issuance.

(b) The Corporation shall collect the Withholding Taxes with respect to the distributed phantom dividend equivalents by withholding a portion of that distribution equal to the amount of the applicable Withholding
Taxes, with the cash portion of the distribution to be the first portion so withheld. Until such time as the Corporation provides the Participant with at least thirty (30) days prior written or electronic notice to the contrary, the Corporation
shall collect the Withholding Taxes with respect to the vested Shares through an automatic Share withholding procedure pursuant to which the Corporation will withhold, immediately as the Shares vest under the Award, a portion of those vested Shares
with a Fair Market Value (measured as of the vesting date) equal to the amount of such Withholding Taxes (the Share Withholding Method); provided,
however, that the amount of any Shares so withheld shall not exceed the amount necessary to satisfy the Corporations required tax withholding obligations using the minimum statutory withholding rates
for federal and state tax purposes, including payroll taxes, that are applicable to supplemental taxable income. The Participant shall be notified in writing or electronically in the event such Share Withholding Method is no longer available.

(c) Should any Shares vest under the Award at time the Share Withholding Method is not available, then the Withholding Taxes shall be
collected from the Participant through either of the following alternatives:

 the Participants delivery of
his or her separate check payable to the Corporation in the amount of such Withholding Taxes, or

 the use of the
proceeds from a next-day sale of the Shares issued to the Participant, provided and only if (i) such a sale is permissible under the Corporations trading policies governing the sale of Common Stock, (ii) the Participant makes an
irrevocable commitment, on or before the vesting date for those Shares, to effect such sale of the Shares and (iii) the transaction is not otherwise deemed to constitute a prohibited loan under Section 402 of the Sarbanes-Oxley Act of
2002.

(d) Except as otherwise provided in Paragraph 5 or this Paragraph 7, the settlement of all Restricted Stock Units which vest under
the Award shall be made solely in shares of Common Stock. In no event, however, shall any fractional shares be issued. Accordingly, the total number of shares of Common Stock to be issued at the time the Award vests shall, to the extent necessary,
be rounded down to the next whole share in order to avoid the issuance of a fractional share.

---

8. Compliance with Laws and Regulations. The issuance of shares of Common Stock pursuant to
the Award shall be subject to compliance by the Corporation and the Participant with all applicable requirements of law relating thereto and with all applicable regulations of any stock exchange (or the Nasdaq National Market, if applicable) on
which the Common Stock may be listed for trading at the time of such issuance.

9. Notices. Any notice required to be given
or delivered to the Corporation under the terms of this Agreement shall be in writing and addressed to the Corporation at its principal corporate offices. Except to the extent electronic notice is expressly authorized hereunder, any notice required
to be given or delivered to the Participant shall be in writing and addressed to the Participant at the address indicated below the Participants signature line on this Agreement. All notices shall be deemed effective upon personal delivery (or
electronic delivery to the extent authorized hereunder) or upon deposit in the U.S. mail, postage prepaid and properly addressed to the party to be notified.

10. Successors and Assigns. Except to the extent otherwise provided in this Agreement, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the Corporation and its
successors and assigns and the Participant, the Participants assigns, the legal representatives, heirs and legatees of the Participants estate and any beneficiaries of the Award designated by the Participant.

11. Construction. This Agreement and the Award evidenced hereby are made and granted pursuant to the Plan and are in all respects limited
by and subject to the terms of the Plan. All decisions of the Plan Administrator with respect to any question or issue arising under the Plan or this Agreement shall be conclusive and binding on all persons having an interest in the Award.

12. Governing Law. The interpretation, performance and enforcement of this Agreement shall be governed by the laws of the
State of Delaware without resort to that States conflict-of-laws rules.

13. Employment at Will. Nothing in this
Agreement or in the Plan shall confer upon the Participant any right to continue in Service for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Corporation (or any Parent or Subsidiary employing
or retaining the Participant) or of the Participant, which rights are hereby expressly reserved by each, to terminate the Participants Service at any time for any reason, with or without cause.
