|Issuance Schedule |  | Each Share in which the Participant vests in accordance with the applicable provisions of the foregoing Vesting
Schedule will become issuable on the date (the Issuance Date) upon which occurs the earliest of the following: (i) the date of the Participants Separation from Service, (ii) the closing date of a Change in Control or
(iii) the issuance date determined for that Share in accordance with the following schedule based on the period during which that Share vests in accordance with such Vesting Schedule:

Vesting Period
                                        
Issuance Date  
  
 The actual issuance of the Shares shall be subject to the
Corporations collection of all applicable Withholding Taxes and shall be effected on the applicable Issuance Date or as soon as administratively practicable thereafter, but in no event later than (A) the close of the calendar year in which an
Issuance Date triggered by the Participants Separation from Service or a Change in Control occurs or (if later) the fifteenth (15th) day of the third calendar month following such Issuance Date or (B) with respect to an Issuance Date
determined under the clause (iii) issuance schedule above, the fifteenth (15th) day of the second calendar month following that Issuance Date, unless in any instance a further deferral is required pursuant to Paragraph 9. The procedures pursuant to
which the applicable Withholding Taxes are to be collected are set forth in Paragraph 8 of this Agreement.

2.       Limited Transferability. Prior to actual receipt of the Shares which vest and become issuable hereunder, the Participant may not transfer any interest
in the Award or the underlying Shares. 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 re-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. Except as otherwise provided in Paragraph 4 below, 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. Should the Participants Service terminate by reason of a
Termination for Cause, then this Award will be immediately cancelled with respect to all the Restricted Stock Units subject to such Award, whether vested or unvested at the time, and the Participant shall thereupon cease to have any right or
entitlement to receive any Shares under this Award and the cancelled Restricted Stock Units.

4.      Accelerated Vesting. The following special vesting acceleration
provisions shall be in effect for the Award and shall be in addition to the vesting acceleration provisions of Paragraph 6 of this Agreement:

(a)      Should the Participant cease Employee status on or after attainment of age sixty-five (65) by reason of death, Disability or an Involuntary Termination (other
than a Termination for Cause), then all the Shares at the time subject to this Award shall immediately vest.

[(b)      Should the Participant cease Employee status prior to attainment of age
sixty-five (65) by reason of death, Disability or Involuntary Termination (other than a Termination for Cause), then the Participant shall immediately vest in an additional number of Shares (if any) equal to the number of Shares necessary to
assure that the total number of Shares in which he has vested at that time is not less than twenty-five percent (25%) of the total number of Shares subject to this Award.]

(c)      The Shares which vest on an accelerated basis pursuant to this Paragraph 4,
together with any other unissued Shares in which the Participant is at the time vested, shall be issued on the date of the Participants Separation from Service (or as soon as administratively practicable thereafter, subject to the
Corporations collection of the applicable Withholding Taxes, but in no event later than the close of the calendar year in which such Separation from Service occurs or (if later) the fifteenth (15th) day of the third calendar month
following the date of such Separation from Service, unless a further deferral is required pursuant to the provisions of Paragraph 9 of this Agreement.

5.      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 upon their actual issuance following the Corporations collection of the applicable Withholding Taxes.

(b)      Notwithstanding the foregoing, should any dividend or other distribution, whether
regular or extraordinary and whether payable in cash, securities or other property (other than shares of Common Stock), 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 equal to the actual dividend or
distribution which would have been paid on the Shares at the time subject to this Award had those Shares been issued and outstanding and entitled to that dividend or distribution. The phantom dividend equivalents so credited shall vest at the



---

same time as the Shares to which they relate and shall be distributed to the Participant (in
the same form the actual dividend or distribution was paid to the holders of the Common Stock entitled to that dividend or distribution or in such other form as the Plan Administrator deems appropriate) concurrently with the issuance of those Shares
on the applicable Issuance Date. However, each such distribution shall be subject to the Corporations collection of the Withholding Taxes applicable to that distribution.

6.      Change of Control.

(a)      Any Restricted Stock Units subject to this Award at the time of a Change in
Control will vest on the closing of that Change in Control. The Shares subject to those vested units will be issued on the Issuance Date triggered by the closing of the Change in Control or as soon as administratively practicable after that Issuance
Date, but in no event later than the close of the calendar year in which such Issuance Date occurs or (if later) the fifteenth (15th) day of the third calendar month following such Issuance Date. Alternatively, the Shares subject to those
vested units shall be converted into the right to receive the same consideration per share of Common Stock payable to the other stockholders of the Corporation in consummation of the Change in Control, and such consideration per Share shall be
distributed on the Issuance Date triggered by the closing of the Change in Control or as soon as administratively practicable after that Issuance Date, but in no event later than the close of the calendar year in which such Issuance Date occurs or
(if later) the fifteenth (15th) day of the third calendar month following such Issuance Date. Such issuance or distribution shall be subject to the Corporations collection of the applicable Withholding Taxes in accordance with the
procedure set forth in Paragraph 8 of this Agreement.

(b)      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.

7.      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, spin-off transaction, extraordinary dividend or distribution or other change affecting the outstanding Common Stock as a
class without the Corporations receipt of consideration, or should the value of outstanding shares of Common Stock be substantially reduced as a result of a spin-off transaction or an extraordinary dividend or distribution, or should there
occur any merger, consolidation or other reorganization, then equitable adjustments shall be made by the Plan Administrator to the total number and/or class of securities issuable pursuant to this Award in order to reflect such change. In making
such equitable adjustments, the Plan Administrator shall take into account any amounts credited to the Participants book account under Paragraph 5(b) in connection with the transaction. The determination of the Plan Administrator shall be
final, binding and conclusive. In the event of a Change in Control, the adjustments (if any) shall be made in accordance with the provisions of Paragraph 6.



---

8.       Collection of Withholding
Taxes.

(a)       The Corporation shall collect the applicable
Withholding Taxes with respect to the distribution of the phantom dividend equivalents to the Participant by withholding a portion of that distribution equal to the amount of those 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 notice to the contrary, the Corporation shall collect the applicable Withholding Taxes with respect to the issuance of the Shares that vest hereunder through an
automatic Share withholding procedure pursuant to which the Corporation will withhold, at the time of such issuance, a portion of the Shares with a Fair Market Value (measured as of the issuance date) equal to the amount of those 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 that are applicable to supplemental taxable income. Participant shall be notified in writing in the event such Share Withholding Method is no longer available.

(b)       Should any Shares be distributed at time the Share Withholding Method is not
available, then the federal, state and local income taxes required to be withheld with respect to those Shares 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 Issuance Date for those Shares, to effect such sale of the Shares and (iii) the transaction is not otherwise deemed to involve a prohibited loan under
Section 402 of the Sarbanes-Oxley Act of 2002.

(c)       Should any other
amounts become distributable to Participant in consideration for the Shares, then the applicable Withholding Taxes with respect to those amounts shall be collected from the Participant pursuant to such procedures as the Corporation deems appropriate
under the circumstances, including (without limitation) the Participants delivery of his or her separate check payable to the Corporation in the amount of such Withholding Taxes.

(d)       Notwithstanding the foregoing provisions of this Paragraph 8, the employee
portion of the federal, state and local employment taxes required to be withheld by the Corporation in connection with the vesting of the Shares or any other amounts hereunder (the Employment Taxes) shall in all events be collected from
the Participant no later than the last business day of the calendar year in which the Shares or other amounts vest hereunder. Accordingly, to the extent the applicable issuance date for one or more vested Shares or the distribution date for such
other amounts is to occur in a year subsequent to the calendar year in which those Shares or other amounts vest, the Participant shall, on or before the last business day



---

of the calendar year in which the Shares or other amounts vest, deliver to the Corporation a
check payable to its order in the dollar amount equal to the Employment Taxes required to be withheld with respect to those Shares or other amounts. The provisions of this Paragraph 8(d) shall be applicable only to the extent necessary to comply
with the applicable tax withholding requirements of Code Section 3121(v).

(e)
      Except as otherwise provided in Paragraph 6 and Paragraph 8(a), 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 pursuant to the Award shall, to the extent necessary, be rounded down to the next whole share in order to avoid the issuance of a fractional share.

9. Deferred Issue Date. Notwithstanding any provision to
the contrary in this Agreement, no Shares which become issuable by reason of the Participants Separation from Service shall actually be issued to a Participant prior to the earlier of (i) the first day of the seventh
(7th) month following the date of such Separation from Service or (ii) the date of Participants death, if Participant is deemed at the time of such Separation from Service to be a specified employee under Section 1.409A-1(i) of
the Treasury Regulations issued under Code Section 409A, as determined by the Plan Administrator in accordance with consistent and uniform standards applied to all other Code Section 409A arrangements of the Corporation, and such delayed
commencement is otherwise required in order to avoid a prohibited distribution under Code Section 409A(a)(2). The deferred Shares or other distributable amount shall be issued or distributed in a lump sum on the first day of the seventh
(7th) month following the date of Participants Separation from Service or, if earlier, the first day of the month immediately following the date the Corporation receives proof of Participants death.

10.       Benefit Limit. In the event the vesting and issuance
of the Shares subject to this Award would otherwise constitute a parachute payment under Code Section 280G, then the vesting and issuance of those Shares shall be subject to reduction to the extent necessary to assure that the number of Shares
which vest and are issued under this Award will be limited to the greater of (i) the number of Shares which can vest and be issued without triggering a parachute payment under Code Section 280G or (ii) the maximum number
of Shares which can vest and be issued under this Award so as to provide the Participant with the greatest after-tax amount of such vested and issued Shares after taking into account any excise tax the Participant may incur under Code
Section 4999 with respect to those Shares and any other benefits or payments to which the Participant may be entitled in connection with any change in control or ownership of the Corporation or the subsequent termination of the
Participants Service.

ALTERNATIVE

10. Benefit Limit.In the event the vesting and
issuance of the Shares subject to this Award would constitute a parachute payment under Code Section 280G, the Participant shall become entitled to the tax gross-up payment in accordance with the terms and provisions of Section
 of his Employment Agreement, to the extent such agreement in effect at that time. Otherwise, the vesting and issuance of those Shares shall be subject to reduction to
the extent necessary to assure that the number of Shares which vest and are issued under this Award will be



---

limited to the greater of (i) the number of Shares which can vest and be
issued without triggering a parachute payment under Code Section 280G or (ii) the maximum number of Shares which can vest and be issued under this Award so as to provide the Participant with the greatest after-tax amount of such vested and
issued Shares after taking into account any excise tax the Participant may incur under Code Section 4999 with respect to those Shares and any other benefits or payments to which the Participant may be entitled in connection with any change in
control or ownership of the Corporation or the subsequent termination of the Participants Service.

11.
      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 Participant with all applicable requirements
of law relating thereto and with all applicable regulations of the Stock exchange on which the Common Stock is listed for trading at the time of such issuance.

12.       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. Any notice required to be given or delivered to Participant shall be in writing and addressed to Participant at
the address indicated below Participants signature line on this Agreement. All notices shall be deemed effective upon personal delivery or upon deposit in the U.S. mail, postage prepaid and properly addressed to the party to be notified.

13.       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 Participant, Participants assigns, the legal representatives, heirs and
legatees of Participants estate and any beneficiaries of the Award designated by Participant.

14.
      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. To the extent there is any ambiguity as to whether one or more
provisions of this Agreement would otherwise contravene any requirements or limitations of Code Section 409A applicable to the Award evidenced hereby, then those provisions shall be interpreted and applied in a manner that does not result in a
violation of any requirements or limitations of Code Section 409A and the Treasury Regulations thereunder that may be applicable to the Award. In addition, each installment issuance of Shares pursuant to this Agreement shall be deemed a
separate payment. for all relevant purposes under Code Section 409A.

15.
      Governing Law. The interpretation, performance and enforcement of this Agreement shall be governed by the laws of the State of California without resort to that States conflict-of-laws rules.

16.      Employment at Will.
Nothing in this Agreement or in the Plan shall confer upon 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 Participant) or of Participant, which rights are hereby expressly reserved by each, to terminate Participants Service at any time for any reason, with or without cause.

IN WITNESS WHEREOF, the parties have executed this Agreement on the day and year first indicated above.
