STOCK INCENTIVE PLAN


 


ARTICLE
ONE

GENERAL PROVISIONS


 


I.Purpose
of the Plan.


 


This
2016 Stock Incentive Plan is intended to promote the interests of Pacific Ethanol, Inc. by providing eligible persons in the Corporation’s
service with the opportunity to acquire a proprietary or economic interest, or otherwise increase their proprietary or economic
interest, in the Corporation as an incentive for them to remain in such service and render superior performance during such service.
Capitalized terms not otherwise defined herein shall have the meanings assigned to such terms in the attached Appendix.


 


II.Structure
of the Plan.


 


A.The
Plan is divided into two equity-based incentive programs:


 


	 	●	the
    Discretionary Grant Program, under which eligible persons may, at the discretion of the Plan Administrator, be granted options
    to purchase shares of common stock or stock appreciation rights tied to the value of such common stock; and
	 	 	 
	 	●	the
    Stock Issuance Program, under which eligible persons may be issued shares of common stock pursuant to restricted stock or
    restricted stock unit awards or other stock-based awards, made by and at the discretion of the Plan Administrator, that vest
    upon the completion of a designated service period and/or the attainment of pre-established performance milestones, or under
    which shares of common stock may be issued through direct purchase or as a bonus for services rendered to the Corporation
    (or any Parent or Subsidiary).


 


B.The
provisions of Articles One and Four shall apply to all equity programs under the Plan and shall govern the interests of
all persons under the Plan.


 


III.Administration
of the Plan.


 


A.The
Compensation Committee shall have sole and exclusive authority to administer the Discretionary Grant and Stock Issuance Programs,
provided, however, that the Board may retain, reassume or exercise from time to time the power to administer those programs with
respect to all persons. However, any discretionary Awards to members of the Compensation Committee must be authorized and approved
by a disinterested majority of the Board.


 


B.The
Plan Administrator shall, within the scope of its administrative functions under the Plan, have full power and authority (subject
to the provisions of the Plan) to establish such rules and regulations as it may deem appropriate for proper administration of
the Discretionary Grant and Stock Issuance Programs and to make such determinations under, and issue such interpretations of,
the provisions of those programs and any outstanding Awards thereunder as it may deem necessary or advisable. Decisions of the
Plan Administrator within the scope of its administrative functions under the Plan shall be final and binding on all parties who
have an interest in the Discretionary Grant and Stock Issuance Programs under its jurisdiction or any Award thereunder.


 


C.Service
on the Compensation Committee shall constitute service as a Board member, and members of each such committee shall accordingly
be entitled to full indemnification and reimbursement as Board members for their service on such committee. No member of the Compensation
Committee shall be liable for any act or omission made in good faith with respect to the Plan or any Award under the Plan.

IV.Eligibility.


 


A.The
persons eligible to participate in the Discretionary Grant and Stock Issuance Programs are as follows:


 


(i)Employees;


 


(ii)non-employee
members of the Board or the board of directors of any Parent or Subsidiary; and


 


(iii)Consultants.


 


B.The
Plan Administrator shall, within the scope of its administrative jurisdiction under the Plan, have full authority to determine
(i) with respect to Awards made under the Discretionary Grant Program, which eligible persons are to receive such Awards, the
time or times when those Awards are to be made, the number of shares to be covered by each such Award, the status of any awarded
option as either an Incentive Option or a Non-Statutory Option, the exercise price per share in effect for each Award (subject
to the limitations set forth in Article Two), the time or times when each Award is to vest and become exercisable and the
maximum term for which the Award is to remain outstanding, and (ii) with respect to Awards under the Stock Issuance Program, which
eligible persons are to receive such Awards, the time or times when the Awards are to be made, the number of shares subject to
each such Award, the vesting schedule (if any) applicable to the shares subject to such Award, and the cash consideration (if
any) payable for such shares.


 


C.The
Plan Administrator shall have the absolute discretion to grant options or stock appreciation rights in accordance with the Discretionary
Grant Program and to effect stock issuances or other stock-based awards in accordance with the Stock Issuance Program.


 


V.Stock
Subject to the Plan.


 


A.The
stock issuable under the Plan shall be shares of authorized but unissued or reacquired common stock, including shares repurchased
by the Corporation on the open market. Subject to any additional shares authorized by the vote of the Board and approved by the
stockholders, the number of shares of common stock reserved for issuance over the term of the Plan shall not exceed 1,150,000
shares. Any or all of the shares of common stock reserved for issuance under the Plan shall be authorized for issuance pursuant
to Incentive Options or other Awards.


 


B.No
one person participating in the Plan may be granted Awards of common stock having a Fair Market Value on the applicable grant
date(s) of more than One Million Dollars ($1,000,000) in the aggregate per calendar year.


 


C.Shares
of common stock subject to outstanding Awards under the Plan shall in no event become eligible for reissuance under the Plan,
whether as a result of expiration or termination of an Award, cancellation or repurchase of unvested shares, tender of shares
in connection with a net/cashless exercise program, withholding of shares to cover withholding taxes, or otherwise.


 




    	 	2	 



     

    


 


D.If
any change is 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, appropriate adjustments shall be made by the Plan Administrator to (i) the maximum number and/or class of securities
issuable under the Plan, (ii) the maximum number and/or class of securities for which any one person may be granted Awards under
the Plan per calendar year, (iii) the number and/or class of securities and the exercise or base price per share (or any other
cash consideration payable per share) in effect under each outstanding Award under the Discretionary Grant Program, and (iv) the
number and/or class of securities subject to each outstanding Award under the Stock Issuance Program and the cash consideration
(if any) payable per share thereunder. To the extent such adjustments are to be made to outstanding Awards, those adjustments
shall be effected in a manner that shall preclude the enlargement or dilution of rights and benefits under those Awards. The adjustments
determined by the Plan Administrator shall be final, binding and conclusive.


 


VI.Clawback
Policy.


 


The
Plan Administrator shall, notwithstanding anything to the contrary contained in any Award document or in any employment or other
agreement, have full power and authority to modify or terminate any vested or unvested Award or require repayment to the Corporation
of the net proceeds received by a participant arising from any Award, to apply the Corporation’s Policy for Recoupment of
Incentive Compensation dated March 25, 2011, as such policy may be amended by the Corporation from time to time, or any successor
“clawback” or similar policy adopted by the Corporation, including any such policy or policy changes mandated by or
implemented pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act or the applicable listing requirements or
rules and regulations of The NASDAQ Capital Market, if applicable, and any other stock exchange or other market on which common
stock is then quoted or listed for trading.


 


ARTICLE
TWO

DISCRETIONARY GRANT PROGRAM


 


I.Option
Terms.


 


Each
option shall be evidenced by one or more documents in the form approved by the Plan Administrator; provided, however, that each
such document shall comply with the terms specified below. Each document evidencing an Incentive Option shall, in addition, be
subject to the provisions of the Plan applicable to such options.


 


A.Exercise
Price.


 


1.The
exercise price per share shall be fixed by the Plan Administrator but shall not be less than 85% of the Fair Market Value per
share of common stock on the option grant date.


 


2.The
exercise price shall become immediately due upon exercise of the option and shall be payable in one or more of the following forms
that the Plan Administrator may deem appropriate in each individual instance:


 


(i)cash
or check made payable to the Corporation;


 


(ii)shares
of common stock valued at Fair Market Value on the Exercise Date and held for the period (if any) necessary to avoid any additional
charges to the Corporation’s earnings for financial reporting purposes; or


 


(iii)to
the extent the option is exercised for vested shares, through a special sale and remittance procedure pursuant to which the Optionee
shall concurrently provide irrevocable instructions to (a) a brokerage firm to effect the immediate sale of the purchased shares
and remit to the Corporation, out of the sale proceeds available on the settlement date, sufficient funds to cover the aggregate
exercise price payable for the purchased shares plus all applicable federal, state and local income and employment taxes required
to be withheld by the Corporation by reason of such exercise and (b) the Corporation to deliver the certificates for the purchased
shares directly to such brokerage firm to complete the sale.


 




    	 	3	 



     

    


 


Except
to the extent such sale and remittance procedure is utilized, payment of the exercise price for the purchased shares must be made
on the Exercise Date.


 


B.Exercise
and Term of Options. Each option shall be exercisable at such time or times, during such period and for such number of
shares as shall be determined by the Plan Administrator and set forth in the documents evidencing the option. However, no option
shall have a term in excess of ten years measured from the option grant date.


 


C.Effect
of Termination of Service.


 


1.The
following provisions shall govern the exercise of any options held by the Optionee at the time of cessation of Service or death:


 


(i)Any
option outstanding at the time of the Optionee’s cessation of Service for any reason shall remain exercisable for such period
of time thereafter as shall be determined by the Plan Administrator and set forth in the documents evidencing the option or as
otherwise specifically authorized by the Plan Administrator in its sole discretion pursuant to an express written agreement with
Optionee, but no such option shall be exercisable after the expiration of the option term.


 


(ii)Any
option held by the Optionee at the time of death and exercisable in whole or in part at that time may be subsequently exercised
by the personal representative of the Optionee’s estate or by the person or persons to whom the option is transferred pursuant
to the Optionee’s will or the laws of inheritance or by the Optionee’s designated beneficiary or beneficiaries of
that option.


 


(iii)During
the applicable post-Service exercise period, the option may not be exercised in the aggregate for more than the number of vested
shares for which that option is at the time exercisable. No additional shares shall vest under the option following the Optionee’s
cessation of Service, except to the extent (if any) specifically authorized by the Plan Administrator in its sole discretion pursuant
to an express written agreement with Optionee. Upon the expiration of the applicable exercise period or (if earlier) upon the
expiration of the option term, the option shall terminate and cease to be outstanding for any shares for which the option has
not been exercised.


 


2.The
Plan Administrator shall have complete discretion, exercisable either at the time an option is granted or at any time while the
option remains outstanding, to:


 


(i)extend
the period of time for which the option is to remain exercisable following the Optionee’s cessation of Service from the
limited exercise period otherwise in effect for that option to such greater period of time as the Plan Administrator shall deem
appropriate, but in no event beyond the expiration of the option term, and/or


 


(ii)permit
the option to be exercised, during the applicable post-Service exercise period, not only with respect to the number of vested
shares of common stock for which such option is exercisable at the time of the Optionee’s cessation of Service but also
with respect to one or more additional installments in which the Optionee would have vested had the Optionee continued in Service.


 




    	 	4	 



     

    


 


D.Stockholder
Rights. The holder of an option shall have no stockholder rights with respect to the shares subject to the option until
such person shall have exercised the option, paid the exercise price and become a holder of record of the purchased shares.


 


E.Repurchase
Rights. The Plan Administrator shall have the discretion to grant options that are exercisable for unvested shares of
common stock. Should the Optionee cease Service while holding such unvested shares, the Corporation shall have the right to repurchase,
at the exercise price paid per share, any or all of those unvested shares. The terms upon which such repurchase right shall be
exercisable (including the period and procedure for exercise and the appropriate vesting schedule for the purchased shares) shall
be established by the Plan Administrator and set forth in the document evidencing such repurchase right.


 


F.Transferability
of Options. The transferability of options granted under the Plan shall be governed by the following provisions:


 


(i)Incentive
Options. During the lifetime of the Optionee, Incentive Options shall be exercisable only by the Optionee and shall not
be assignable or transferable other than by will or the laws of inheritance following the Optionee’s death.


 


(ii)Non-Statutory
Options. Non-Statutory Options shall be subject to the same limitation on transfer as Incentive Options, except that the
Plan Administrator may structure one or more Non-Statutory Options so that the option may be assigned in whole or in part during
the Optionee’s lifetime to one or more Family Members of the Optionee or to a trust established exclusively for the Optionee
and/or one or more such Family Members, to the extent such assignment is in connection with the Optionee’s estate plan or
pursuant to a domestic relations order. The assigned portion may only be exercised by the person or persons who acquire a proprietary
interest in the option pursuant to the assignment. The terms applicable to the assigned portion shall be the same as those in
effect for the option immediately prior to such assignment and shall be set forth in such documents issued to the assignee as
the Plan Administrator may deem appropriate.


 


(iii)Beneficiary
Designations. Notwithstanding the foregoing, the Optionee may designate one or more persons as the beneficiary or beneficiaries
of his or her outstanding options under this Article Two (whether Incentive Options or Non-Statutory Options), and those
options shall, in accordance with such designation, automatically be transferred to such beneficiary or beneficiaries upon the
Optionee’s death while holding those options. Such beneficiary or beneficiaries shall take the transferred options subject
to all the terms and conditions of the applicable agreement evidencing each such transferred option, including (without limitation)
the limited time period during which the option may be exercised following the Optionee’s death.


 


II.Incentive
Options.


 


The
terms specified below, together with any additions, deletions or changes thereto imposed from time to time pursuant to the provisions
of the Code governing Incentive Options, shall be applicable to all Incentive Options. Except as modified by the provisions of
this Section II, all the provisions of Articles One, Two and Four shall be applicable to Incentive Options. Options
that are specifically designated as Non-Statutory Options when issued under the Plan shall not be subject to the terms of this
Section II.


 


A.Eligibility.
Incentive Options may only be granted to Employees.


 




    	 	5	 



     

    


 


B.Exercise
Price. The exercise price per share shall not be less than 100% of the Fair Market Value per share of common stock on
the option grant date.


 


C.Dollar
Limitation. The aggregate Fair Market Value of the shares of common stock (determined as of the respective date or dates
of grant) for which one or more options granted to any Employee under the Plan (or any other option plan of the Corporation or
any Parent or Subsidiary) may for the first time become exercisable as Incentive Options during any one calendar year shall not
exceed the sum of One Hundred Thousand Dollars ($100,000). To the extent the Employee holds two or more such options which become
exercisable for the first time in the same calendar year, then for purposes of the foregoing limitation on the exercisability
of those options as Incentive Options, such options shall be deemed to become first exercisable in that calendar year on the basis
of the chronological order in which they were granted, except to the extent otherwise provided under applicable law or regulation.


 


D.10%
Stockholder. If any Employee to whom an Incentive Option is granted is a 10% Stockholder, then the exercise price per
share shall not be less than 110% of the Fair Market Value per share of common stock on the option grant date, and the option
term shall not exceed five years measured from the option grant date.


 


III.Stock
Appreciation Rights.


 


A.Authority.
The Plan Administrator shall have full power and authority, exercisable in its sole discretion, to grant stock appreciation rights
in accordance with this Section III to selected Optionees or other individuals eligible to receive option grants under
the Discretionary Grant Program.


 


B.Types.
Three types of stock appreciation rights shall be authorized for issuance under this Section III: (i) tandem stock appreciation
rights (“Tandem Rights”), (ii) standalone stock appreciation rights (“Standalone Rights”)
and (iii) limited stock appreciation rights (“Limited Rights”).


 


C.Tandem
Rights. The following terms and conditions shall govern the grant and exercise of Tandem Rights.


 


1.One
or more Optionees may be granted a Tandem Right, exercisable upon such terms and conditions as the Plan Administrator may establish,
to elect between the exercise of the underlying stock option for shares of common stock or the surrender of that option in exchange
for a distribution from the Corporation in an amount equal to the excess of (i) the Fair Market Value (on the option surrender
date) of the number of shares in which the Optionee is at the time vested under the surrendered option (or surrendered portion
thereof) over (ii) the aggregate exercise price payable for such vested shares.


 


2.No
such option surrender shall be effective unless it is approved by the Plan Administrator, either at the time of the actual option
surrender or at any earlier time. If the surrender is so approved, then the distribution to which the Optionee shall accordingly
become entitled under this Section III may be made in shares of common stock valued at Fair Market Value on the option
surrender date, in cash, or partly in shares and partly in cash, as the Plan Administrator shall in its sole discretion deem appropriate.


 


3.If
the surrender of an option is not approved by the Plan Administrator, then the Optionee shall retain whatever rights the Optionee
had under the surrendered option (or surrendered portion thereof) on the option surrender date and may exercise such rights at
any time prior to the later of (i) five business days after the receipt of the rejection notice or (ii) the last day on which
the option is otherwise exercisable in accordance with the terms of the instrument evidencing such option, but in no event may
such rights be exercised more than ten years after the date of the option grant.


 




    	 	6	 



     

    


 


D.Standalone
Rights. The following terms and conditions shall govern the grant and exercise of Standalone Rights under this Article
Two:


 


1.One
or more individuals eligible to participate in the Discretionary Grant Program may be granted a Standalone Right not tied to any
underlying option under this Discretionary Grant Program. The Standalone Right shall relate to a specified number of shares of
common stock and shall be exercisable upon such terms and conditions as the Plan Administrator may establish. In no event, however,
may the Standalone Right have a maximum term in excess of ten years measured from the grant date. Upon exercise of the Standalone
Right, the holder shall be entitled to receive a distribution from the Corporation in an amount equal to the excess of (i) the
aggregate Fair Market Value (on the exercise date) of the shares of common stock underlying the exercised right over (ii) the
aggregate base price in effect for those shares.


 


2.The
number of shares of common stock underlying each Standalone Right and the base price in effect for those shares shall be determined
by the Plan Administrator in its sole discretion at the time the Standalone Right is granted. In no event, however, may the base
price per share be less than the Fair Market Value per underlying share of common stock on the grant date.


 


3.Standalone
Rights shall be subject to the same transferability restrictions applicable to Non-Statutory Options and may not be transferred
during the holder’s lifetime, except to one or more Family Members of the holder or to a trust established exclusively for
the holder and/or such Family Members, to the extent such assignment is in connection with the holder’s estate plan or pursuant
to a domestic relations order covering the Standalone Right as marital property. In addition, one or more beneficiaries may be
designated for an outstanding Standalone Right in accordance with substantially the same terms and provisions as set forth in
Section I.F of this Article Two.


 


4.The
distribution with respect to an exercised Standalone Right may be made in shares of common stock valued at Fair Market Value on
the exercise date, in cash, or partly in shares and partly in cash, as the Plan Administrator shall in its sole discretion deem
appropriate.


 


5.The
holder of a Standalone Right shall have no stockholder rights with respect to the shares subject to the Standalone Right unless
and until such person shall have exercised the Standalone Right and become a holder of record of shares of common stock issued
upon the exercise of such Standalone Right.


 


E.Limited
Rights. The following terms and conditions shall govern the grant and exercise of Limited Rights under this Article
Two:


 


1.One
or more Section 16 Insiders may, in the Plan Administrator’s sole discretion, be granted Limited Rights with respect to
their outstanding options under this Article Two.


 


2.Upon
the occurrence of a Hostile Take-Over, the Section 16 Insider shall have the unconditional right (exercisable for a 30-day period
following such Hostile Take-Over) to surrender each option with such a Limited Right to the Corporation. The Section 16 Insider
shall in return be entitled to a cash distribution from the Corporation in an amount equal to the excess of (i) the Take-Over
Price of the number of shares in which the Optionee is at the time vested under the surrendered option (or surrendered portion
thereof) over (ii) the aggregate exercise price payable for those vested shares. Such cash distribution shall be made within five
days following the option surrender date.


 




    	 	7	 



     

    


 


3.The
Plan Administrator shall pre-approve, at the time such Limited Right is granted, the subsequent exercise of that right in accordance
with the terms of the grant and the provisions of this Section III. No additional approval of the Plan Administrator or
the Board shall be required at the time of the actual option surrender and cash distribution. Any unsurrendered portion of the
option shall continue to remain outstanding and become exercisable in accordance with the terms of the instrument evidencing such
grant.


 


F.Post-Service
Exercise. The provisions governing the exercise of Tandem, Standalone and Limited Stock Appreciation Rights following
the cessation of the recipient’s Service or the recipient’s death shall be substantially the same as those set forth
in Section I.C of this Article Two for the options granted under the Discretionary Grant Program.


 


IV.Change
in Control/ Hostile Take-Over.


 


A.No
Award outstanding under the Discretionary Grant Program at the time of a Change in Control shall vest and become exercisable on
an accelerated basis if and to the extent that: (i) such Award is, in connection with the Change in Control, assumed by the successor
corporation (or parent thereof) or otherwise continued in full force and effect pursuant to the terms of the Change in Control
transaction, (ii) such Award is replaced with a cash retention program of the successor corporation that preserves the spread
existing at the time of the Change in Control on the shares of common stock as to which the Award is not otherwise at that time
vested and exercisable and provides for subsequent payout of that spread in accordance with the same exercise/vesting schedule
applicable to those shares, or (iii) the acceleration of such Award is subject to other limitations imposed by the Plan Administrator.
However, if none of the foregoing conditions are satisfied, each Award outstanding under the Discretionary Grant Program at the
time of the Change in Control but not otherwise vested and exercisable as to all the shares at the time subject to that Award
shall automatically accelerate so that each such Award shall, immediately prior to the effective date of the Change in Control,
vest and become exercisable as to all the shares of common stock at the time subject to that Award and may be exercised as to
any or all of those shares as fully vested shares of common stock.


 


B.All
outstanding repurchase rights under the Discretionary Grant Program shall also terminate automatically, and the shares of common
stock subject to those terminated rights shall immediately vest in full, in the event of any Change in Control, except to the
extent: (i) those repurchase rights are assigned to the successor corporation (or parent thereof) or otherwise continue in full
force and effect pursuant to the terms of the Change in Control transaction or (ii) such accelerated vesting is precluded by other
limitations imposed by the Plan Administrator.


 


C.Immediately
following the consummation of the Change in Control, all outstanding Awards under the Discretionary Grant Program shall terminate
and cease to be outstanding, except to the extent assumed by the successor corporation (or parent thereof) or otherwise expressly
continued in full force and effect pursuant to the terms of the Change in Control transaction.


 


D.Each
option that is assumed in connection with a Change in Control or otherwise continued in effect shall be appropriately adjusted,
immediately after such Change in Control, to apply to the number and class of securities that would have been issuable to the
Optionee in consummation of such Change in Control had the option been exercised immediately prior to such Change in Control.
In the event outstanding Standalone Rights are to be assumed in connection with a Change in Control transaction or otherwise continued
in effect, the shares of common stock underlying each such Standalone Right shall be adjusted immediately after such Change in
Control to apply to the number and class of securities into which those shares of common stock would have been converted in consummation
of such Change in Control had those shares actually been outstanding at that time. Appropriate adjustments to reflect such Change
in Control shall also be made to (i) the exercise price payable per share under each outstanding option, provided the aggregate
exercise price payable for such securities shall remain the same, (ii) the base price per share in effect under each outstanding
Standalone Right, provided the aggregate base price shall remain the same, (iii) the maximum number and/or class of securities
available for issuance over the remaining term of the Plan, and (iv) the maximum number and/or class of securities for which any
one person may be granted Awards under the Plan per calendar year. To the extent the actual holders of the Corporation’s
outstanding common stock receive cash consideration for their common stock in consummation of the Change in Control, the successor
corporation may, in connection with the assumption or continuation of the outstanding Awards under the Discretionary Grant Program,
substitute, for the securities underlying those assumed Awards, 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 such Change in Control transaction.


 




    	 	8	 



     

    


 


E.The
Plan Administrator shall have full power and authority to structure one or more outstanding Awards under the Discretionary Grant
Program so that those Awards shall immediately vest and become exercisable as to all of the shares at the time subject to those
Awards in the event the Optionee’s Service is subsequently terminated by reason of an Involuntary Termination within a designated
period (not to exceed 18 months) following the effective date of any Change in Control or a Hostile Take-Over in which those Awards
do not otherwise vest on an accelerated basis. Any Awards so accelerated shall remain exercisable as to fully vested shares until
the expiration or sooner termination of their term. In addition, the Plan Administrator may structure one or more of the Corporation’s
repurchase rights under the Discretionary Grant Program so that those rights shall immediately terminate with respect to any shares
held by the Optionee at the time of his or her Involuntary Termination, and the shares subject to those terminated repurchase
rights shall accordingly vest in full at that time.


 


F.The
portion of any Incentive Option accelerated in connection with a Change in Control shall remain exercisable as an Incentive Option
only to the extent the applicable One Hundred Thousand Dollar ($100,000) limitation is not exceeded. To the extent such dollar
limitation is exceeded, the accelerated portion of such option shall be exercisable as a Non-Statutory Option under the federal
tax laws.


 


G.Awards
outstanding under the Discretionary Grant Program shall in no 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.

but shall not be less than 100% of the Fair Market Value per share of common stock on the issuance date.


 


2.Shares

under the Stock Issuance Program shall be determined by the Plan Administrator and incorporated into the Stock Issuance Agreement.
Shares of common stock may also be issued under the Stock Issuance Program pursuant to restricted stock awards or restricted stock
units that entitle the recipients to receive the shares underlying those awards and/or units upon the attainment of designated
performance goals or the satisfaction of specified Service requirements or upon the expiration of a designated time period following
the vesting of those awards or units, including (without limitation) a deferred distribution date following the termination of
the Participant’s Service.


 


2.The
Plan Administrator shall also have the discretionary authority, consistent with Code Section 162(m), to structure one or more
Awards under the Stock Issuance Program so that the shares of common stock subject to those Awards shall vest (or vest and become
issuable) upon the achievement of certain pre-established corporate performance goals based on one or more of the following criteria:
(i) return on total stockholders’ equity; (ii) net income per share of common stock; (iii) net income or operating income;
(iv) earnings before interest, taxes, depreciation, amortization and stock-compensation costs, or operating income before depreciation

or customer service collaborations, or the completion of other corporate transactions intended to enhance the Corporation’s
revenue or profitability or expand its customer base; provided, however, that for purposes of items (ii), (iii) and (vii) above,
the Plan Administrator may, at the time the Awards are made, specify certain adjustments to such items as reported in accordance
with generally accepted accounting principles in the U.S. (“GAAP”), which will exclude from the calculation
of those performance goals one or more of the following: certain charges related to acquisitions, stock-based compensation, employer
payroll tax expense on certain stock option exercises, settlement costs, restructuring costs, gains or losses on strategic investments,
non-operating gains or losses, certain other non-cash charges, valuation allowance on deferred tax assets, and the related income
tax effects, purchases of property and equipment, and any extraordinary non-recurring items as described in Accounting Principles
Board Opinion No. 30 or its successor, provided that such adjustments are in conformity with those reported by the Corporation
on a non-GAAP basis. In addition, such performance goals may be based upon the attainment of specified levels of the Corporation’s
performance under one or more of the measures described above relative to the performance of other entities and may also be based
on the performance of any of the Corporation’s business groups or divisions thereof or any Parent or Subsidiary. Performance
goals may include a minimum threshold level of performance below which no award will be earned, levels of performance at which
specified portions of an award will be earned, and a maximum level of performance at which an award will be fully earned. The
Plan Administrator may provide that, if the actual level of attainment for any performance objective is between two specified
levels, the amount of the award attributable to that performance objective shall be interpolated on a straight-line basis.

3.Any
new, substituted or additional securities or other property (including money paid other than as a regular cash dividend) that
the Participant may have the right to receive with respect to the Participant’s unvested shares of common stock by reason
of any stock dividend, stock split, 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 shall be issued subject to (i) the
same vesting requirements applicable to the Participant’s unvested shares of common stock and (ii) such escrow arrangements
as the Plan Administrator shall deem appropriate.


 


4.The
Participant shall have full stockholder rights with respect to any shares of common stock issued to the Participant under the
Stock Issuance Program, whether or not the Participant’s interest in those shares is vested. Accordingly, the Participant
shall have the right to vote such shares and to receive any regular cash dividends paid on such shares. The Participant shall
not have any stockholder rights with respect to the shares of common stock subject to a restricted stock unit award until that
award vests and the shares of common stock are actually issued thereunder. However, dividend-equivalent units may be paid or credited,
either in cash or in actual or phantom shares of common stock, on outstanding restricted stock unit or restricted stock awards,
subject to such terms and conditions as the Plan Administrator may deem appropriate.


 


5.Should
the Participant cease to remain in Service while holding one or more unvested shares of common stock issued under the Stock Issuance
Program or should the performance objectives not be attained with respect to one or more such unvested shares of common stock,
then except as set forth in Section I.C.6 of this Article Three, those shares shall be immediately surrendered to
the Corporation for cancellation, and the Participant shall have no further stockholder rights with respect to those shares. To
the extent the surrendered shares were previously issued to the Participant for consideration paid in cash, cash equivalent or
otherwise, the Corporation shall repay to the Participant the same amount and form of consideration as the Participant paid for
the surrendered shares.


 


6.The
Plan Administrator may in its discretion waive the surrender and cancellation of one or more unvested shares of common stock that
would otherwise occur upon the cessation of the Participant’s Service or the non-attainment of the performance objectives
applicable to those shares. Any such waiver shall result in the immediate vesting of the Participant’s interest in the shares
of common stock as to which the waiver applies. Such waiver may be effected at any time, whether before or after the Participant’s
cessation of Service or the attainment or non-attainment of the applicable performance objectives. However, no vesting requirements
tied to the attainment of performance objectives may be waived with respect to shares that were intended at the time of issuance
to qualify as performance-based compensation under Code Section 162(m), except in the event of the Participant’s Involuntary
Termination or as otherwise provided in Section II.E of this Article Three.


 




    	 	11	 



     

    


 


7.Outstanding
restricted stock awards or restricted stock units under the Stock Issuance Program shall automatically terminate, and no shares
of common stock shall actually be issued in satisfaction of those awards or units, if the performance goals or Service requirements
established for such awards or units are not attained or satisfied. The Plan Administrator, however, shall have the discretionary
authority to issue vested shares of common stock under one or more outstanding restricted stock awards or restricted stock units
as to which the designated performance goals or Service requirements have not been attained or satisfied. However, no vesting
requirements tied to the attainment of performance goals may be waived with respect to awards or units which were at the time
of grant intended to qualify as performance-based compensation under Code Section 162(m), except in the event of the Participant’s
Involuntary Termination or as otherwise provided in Section II.E of this Article Three.


 


II.Change
in Control/ Hostile Take-Over.


 


A.All
of the Corporation’s outstanding repurchase rights under the Stock Issuance Program shall terminate automatically, and all
the shares of common stock subject to those terminated rights shall immediately vest in full, in the event of any Change in Control,
except to the extent (i) those repurchase rights are to be assigned to the successor corporation (or parent thereof) or otherwise
continued in full force and effect pursuant to the express terms of the Change in Control transaction or (ii) such accelerated
vesting is precluded by other limitations imposed in the Stock Issuance Agreement.


 


B.Each
outstanding Award under the Stock Issuance Program that is assumed in connection with a Change in Control or otherwise continued
in effect shall be adjusted immediately after the consummation of that Change in Control to apply to the number and class of securities
into which the shares of common stock subject to the Award immediately prior to the Change in Control would have been converted
in consummation of such Change in Control had those shares actually been outstanding at that time, and appropriate adjustments
shall also be made to the cash consideration (if any) payable per share thereunder, provided the aggregate amount of such consideration
shall remain the same. If any such Award is not so assumed or otherwise continued in effect or replaced with a cash retention
program which preserves the Fair Market Value of the shares underlying the Award at the time of the Change in Control and provides
for the subsequent payout of that value in accordance with the vesting schedule in effect for the Award at the time of such Change
in Control, such Award shall vest, and the shares of common stock subject to that Award shall be issued as fully-vested shares,
immediately prior to the consummation of the Change in Control.


 


C.The
Plan Administrator shall have full power and authority to structure one or more outstanding Awards under the Stock Issuance Program
so that the shares of common stock subject to those Awards shall immediately vest (or vest and become issuable) as to all of the
shares at the time subject to those Awards in the event the Participant’s Service is subsequently terminated by reason of
an Involuntary Termination within a designated period (not to exceed 18 months) following the effective date of any Change in
Control or a Hostile Take-Over in which those Awards do not otherwise vest on an accelerated basis. In addition, the Plan Administrator
may structure one or more of the Corporation’s repurchase rights under the Stock Issuance Program so that those rights shall
immediately terminate with respect to any shares held by the Participant at the time of his or her Involuntary Termination, and
the shares subject to those terminated repurchase rights shall accordingly vest in full at that time.


 




    	 	12	 



     

    


 


D.The
Plan Administrator’s authority under Paragraph C of this Section II shall also extend to any Award intended to qualify
as performance-based compensation under Code Section 162(m), even though the automatic vesting of those Awards pursuant to Paragraph
C of this Section II may result in their loss of performance-based status under Code Section 162(m).


 


E.Awards
outstanding under the Stock Issuance Program shall in no 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.
