Exhibit 4.1


 





PACIFIC ETHANOL, INC.


2006 STOCK INCENTIVE PLAN


(As Amended Through June 18, 2014)


ARTICLE
ONE

GENERAL PROVISIONS


	I.		Purpose of the Plan.



This 2006 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.






    	1



    	 



    

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 1,715,000 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 be available for subsequent issuance under the Plan to the extent those Awards expire
or terminate for any reason prior to the issuance of the shares of common stock subject to those Awards. Unvested shares issued
under the Plan and subsequently cancelled or repurchased by the Corporation at the original exercise or issue price paid per share
pursuant to the Corporation’s repurchase rights under the Plan shall be added back to the number of shares of common stock
reserved for issuance under the Plan and shall accordingly be available for subsequent reissuance under the Plan. In addition,
should the exercise price of an option under the Plan be paid with shares of common stock, the authorized reserve of common stock
under the Plan shall be reduced only by the net number of shares issued under the exercised stock option. Should shares of common
stock otherwise issuable under the Plan be withheld by the Corporation in satisfaction of the withholding taxes incurred in connection
with the issuance, exercise or vesting of an Award under the Plan, the number of shares of common stock available for issuance
under the Plan shall be reduced only by the net number of shares issued with respect to that Award.






    	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.


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.


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.






    	3



    	 



    

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.


G.           Net Counting. Upon the
exercise of any Tandem, Standalone or Limited Right under this Section III, the share reserve under Section V
of Article One shall only be reduced by the net number of shares actually issued by the Corporation upon such
exercise, and not by the gross number of shares as to which such Tandem, Standalone or Limited Right is exercised.


	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.






    	8



    	 



    

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.


E.           The Plan Administrator shall have
the discretionary authority to structure one or more outstanding Awards under the Discretionary Grant Program so that those Awards
shall, immediately prior to the effective date of a Change in Control or a Hostile Take-Over, vest and become exercisable as to
all the shares at the time subject to those Awards and may be exercised as to any or all of those shares as fully vested shares
of common stock, whether or not those Awards are to be assumed or otherwise continued in full force and effect pursuant to the
express terms of such transaction. In addition, the Plan Administrator shall have the discretionary authority to structure one
or more of the Corporation’s repurchase rights under the Discretionary Grant Program so that those rights shall immediately
terminate at the time of such Change in Control or consummation of such Hostile Take-Over and shall not be assignable to successor
corporation (or parent thereof), and the shares subject to those terminated rights shall accordingly vest in full at the time of
such Change in Control or consummation of such Hostile Take-Over.


F.           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.


G.           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.


H.           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.

ARTICLE THREE

STOCK ISSUANCE PROGRAM


	I.		Stock Issuance Terms.



A.           Issuances. Shares of
common stock may be issued under the Stock Issuance Program through direct and immediate issuances without any intervening option
grants. Each such stock issuance shall be evidenced by a Stock Issuance Agreement that complies with the terms specified below.
Shares of common stock may also be issued under the Stock Issuance Program pursuant to restricted stock awards or restricted stock
units, awarded by and at the discretion of the Plan Administrator, that entitle the recipients to receive the shares underlying
those awards or units upon the attainment of designated performance goals and/or the satisfaction of specified Service requirements
or upon the expiration of a designated time period following the vesting of those awards or units.


B.           Issue Price.


1.           The price per share at which shares of common
stock may be issued under the Stock Issuance Program shall be fixed by the Plan Administrator, but shall not be less than 100%
of the Fair Market Value per share of common stock on the issuance date.


2.           Shares of common stock may be issued under
the Stock Issuance Program for any of the following items of consideration that the Plan Administrator may deem appropriate in
each individual instance:


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


(ii)          past services rendered to the Corporation
(or any Parent or Subsidiary); or


(iii)         any other valid form of consideration
permissible under the Delaware Corporations Code at the time such shares are issued.


C.           Vesting Provisions.


1.           Shares of common stock issued under the Stock
Issuance Program may, in the discretion of the Plan Administrator, be fully and immediately vested upon issuance or may vest in
one or more installments over the Participant’s period of Service and/or upon attainment of specified performance objectives.
The elements of the vesting schedule applicable to any unvested shares of common stock issued 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 and amortization; (v) sales or
revenue targets; (vi) return on assets, capital or investment; (vii) cash flow; (viii) market share; (ix) cost reduction goals;
(x) budget comparisons; (xi) implementation or completion of projects or processes strategic or critical to the Corporation’s
business operations; (xii) measures of customer satisfaction; (xiii) any combination of, or a specified increase in, any of the
foregoing; and (xiv) the formation of joint ventures, research and development collaborations, marketing 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.






    	11



    	 



    

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.


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.






    	12



    	 



    

C.           The Plan Administrator shall have
the discretionary authority to structure one or more unvested Awards under the Stock Issuance Program so that the shares of common
stock subject to those Awards shall automatically vest (or vest and become issuable) in whole or in part immediately upon the occurrence
of a Change in Control or upon the subsequent termination of the Participant’s Service by reason of an Involuntary Termination
within a designated period (not to exceed 18 months) following the effective date of that Change in Control transaction.


D.           The Plan Administrator shall also
have the discretionary authority to structure one or more unvested Awards under the Stock Issuance Program so that the shares of
common stock subject to those Awards shall automatically vest (or vest and become issuable) in whole or in part immediately upon
the occurrence of a Hostile Take-Over or upon the subsequent termination of the Participant’s Service by reason of an Involuntary
Termination within a designated period (not to exceed 18 months) following the effective date of that Hostile Take-Over.


E.           The Plan Administrator’s
authority under Paragraphs C and D 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 or D of
this Section II may result in their loss of performance-based status under Code Section 162(m).


F.           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.


ARTICLE FOUR

MISCELLANEOUS


	I.		Tax Withholding.



A.           The Corporation’s obligation
to deliver shares of common stock upon the issuance, exercise or vesting of Awards under the Plan shall be subject to the satisfaction
of all applicable federal, state and local income and employment tax withholding requirements.


B.           Subject to applicable laws, rules
and regulations and policies of the Corporation, the Plan Administrator may, in its discretion, provide any or all Optionees or
Participants to whom Awards are made under the Plan with the right to utilize any or all of the following methods to satisfy all
or part of the Withholding Taxes to which those holders may become subject in connection with the issuance, exercise or vesting
of those Awards.


(i)           Stock Withholding:
The election to have the Corporation withhold, from the shares of common stock otherwise issuable upon the issuance, exercise or
vesting of those Awards a portion of those shares with an aggregate Fair Market Value equal to the percentage of the Withholding
Taxes (not to exceed 100%) designated by the Optionee or Participant and make a cash payment equal to such Fair Market Value directly
to the appropriate taxing authorities on such individual’s behalf. The shares of common stock so withheld shall not reduce
the number of shares of common stock authorized for issuance under the Plan.


(ii)          Stock
Delivery: The election to deliver to the Corporation, at the time the Award is issued, exercised or vests, one or more
shares of common stock previously acquired by such the Optionee or Participant (other than in connection with the issuance, exercise
or vesting triggering the Withholding Taxes) with an aggregate Fair Market Value equal to the percentage of the Withholding Taxes
(not to exceed 100%) designated by such holder. The shares of common stock so delivered shall not be added to the shares of common
stock authorized for issuance under the Plan.






    	13



    	 



    

(iii)         Sale and Remittance:
The election to deliver to the Corporation, to the extent the Award is issued or exercised for vested shares, through a special
sale and remittance procedure pursuant to which the Optionee or Participant shall concurrently provide irrevocable instructions
to a brokerage firm to effect the immediate sale of the purchased or issued shares and remit to the Corporation, out of the sale
proceeds available on the settlement date, sufficient funds to cover the Withholding Taxes required to be withheld by the Corporation
by reason of such issuance, exercise or vesting.


	II.		Share Escrow/Legends.



Unvested shares issued under the Plan
may, in the Plan Administrator’s discretion, be held in escrow by the Corporation until the Participant’s interest
in such shares vests or may be issued directly to the Participant with restrictive legends on the certificates evidencing those
unvested shares.


	III.		Effective Date and Term of the Plan.



A.           The Plan was initially adopted

on annual awards to any plan participant from 1,000,000 shares to a limit of One Million Dollars ($1,000,000), and (ii) eliminate
the authority of the Plan Administrator to replace outstanding options or stock appreciation rights or pay cash or issue shares
of common stock in consideration of cancelled options or stock appreciation rights. The Plan was amended by the Board on March
6, 2014, subject to stockholder approval, to increase the number of shares authorized for issuance under the Plan from 914,286
shares to 1,715,000 shares.


B.           The Plan shall become effective

	IV.		Amendment, Suspension or Termination of the Plan.



The Board may suspend or terminate the
Plan at any time, without notice, and in its sole discretion. The Board shall have complete and exclusive power and authority to
amend or modify the Plan in any or all respects. However, no such amendment or modification shall materially impair the rights
and obligations with respect to Awards at the time outstanding under the Plan unless the Optionee or the Participant consents to
such amendment or modification. In addition, stockholder approval will be required for any amendment to the Plan that (i) materially
increases the number of shares of common stock available for issuance under the Plan, (ii) materially expands the class of individuals
eligible to receive option grants or other awards under the Plan, (iii) materially increases the benefits accruing to the Optionees
and Participants under the Plan or materially reduces the price at which shares of common stock may be issued or purchased under

authorities having jurisdiction over the Plan, the Awards made under the Plan and the shares of common stock issuable pursuant
to those Awards.


B.           No shares of common stock or other
assets shall be issued or delivered under the Plan unless and until there shall have been compliance with all applicable requirements
of federal and state securities laws, including the filing and effectiveness of the Form S-8 registration statement for the shares
of common stock issuable under the Plan, and all applicable listing requirements of The NASDAQ Capital Market, if applicable, and
any stock exchange or other market on which common stock is then quoted or listed for trading.


	VII.		No Employment/ Service Rights.



Nothing in the Plan shall confer upon
the Optionee or 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 such person) or of the Optionee
or the Participant, which rights are hereby expressly reserved by each, to terminate such person’s Service at any time for
any reason, with or without cause.


	VIII.		Non-Exclusivity of the Plan.



Nothing contained in the Plan is intended
to amend, modify, or rescind any previously approved compensation plans, programs or options entered into by the Corporation. This
Plan shall be construed to be in addition to and independent of any and all other arrangements. Neither the adoption of the Plan
by the Board nor the submission of the Plan to the stockholders of the Corporation for approval shall be construed as creating
any limitations on the power or authority of the Board to adopt, with or without stockholder approval, such additional or other
compensation arrangements as the Board may from time to time deem desirable.



    	15



    	 



    




	IX.		Governing Law.
