of the offering of any securities of the Company under the Securities Act, require that you not sell, dispose of, transfer, make any short sale of, grant any option for the purchase of, or enter into
any hedging or similar transaction with the same economic effect as a sale, any shares of Common Stock or other securities of the Company held by you, for a period of time specified by the
underwriter(s) (not to exceed one hundred eighty (180) days) following the effective date of the registration statement of the Company filed under the Securities Act. You further agree to
execute and deliver such other agreements as may be reasonably requested by the Company and/or the underwriter(s) that are consistent with the foregoing or that are necessary to give further effect

  Exhibit 10.6    
    

 
  NEWLINK GENETICS CORPORATION    
    
    2009 EQUITY INCENTIVE PLAN    
    
    ADOPTED BY THE BOARD OF DIRECTORS: MAY 13, 2009
  APPROVED BY THE STOCKHOLDERS: JULY 15,
2009
  TERMINATION DATE: MAY 12, 2019    
    
    AMENDED BY THE BOARD: OCTOBER 29, 2010
  APPROVED BY THE
STOCKHOLDERS:                  , 2010    

        1.    GENERAL.    

        (a)    Successor to and Continuation of Prior Plan.    The Plan is intended as the successor to and continuation of
the NewLink Genetics Corporation 2000 Equity Incentive Plan (the "Prior Plan"). Following the Effective Date, no additional stock awards shall be
granted under the Prior Plan. Any shares remaining available for issuance pursuant to the exercise of options or issuance or settlement of stock awards under the Prior Plan as of the Effective Date
(the "Prior Plan's Available Reserve") shall become available for issuance pursuant to Stock Awards granted hereunder. From and after the Effective
Date, all outstanding stock awards granted under the Prior Plan shall remain subject to the terms of the Prior Plan; provided, however, any shares
subject to outstanding stock awards granted under the Prior Plan that expire or terminate for any reason prior to exercise or settlement or are forfeited because of the failure to meet a contingency
or condition required to vest such shares, which shares would otherwise return to the Prior Plan (the "Returning Shares") shall become available for
issuance pursuant to Awards granted hereunder. All Awards granted on or after the Effective Date of this Plan shall be subject to the terms of this Plan. 

        (b)    Eligible Award Recipients.    The persons eligible to receive Awards are Employees, Directors and Consultants. 

        (c)    Available Awards.    The Plan provides for the grant of the following Awards: (i) Incentive Stock
Options, (ii) Nonstatutory Stock Options, (iii) Stock Appreciation Rights (iv) Restricted Stock Awards, (v) Restricted Stock Unit Awards, (vi) Performance Stock
Awards, (vii) Performance Cash Awards, and (viii) Other Stock Awards. 

        (d)    Purpose.    The Company, by means of the Plan, seeks to secure and retain the services of the group of persons
eligible to receive Awards as set forth in Section 1(b), to provide incentives for such persons to exert maximum efforts for the success of the Company and any Affiliate and to provide a means
by which such eligible recipients may be given an opportunity to benefit from increases in value of the Common Stock through the granting of Awards. 

        2.    ADMINISTRATION.    

        (a)    Administration by Board.    The Board shall administer the Plan unless and until the Board delegates
administration of the Plan to a Committee or Committees, as provided in Section 2(c). 

        (b)    Powers of Board.    The Board shall have the power, subject to, and within the limitations of, the express
provisions of the Plan: 

          (i)  To determine from time to time (A) which of the persons eligible under the Plan shall be granted Awards;
(B) when and how each Award shall be granted; (C) what type or combination of types of Award shall be granted; (D) the provisions of each Award granted (which need not be
identical), including the time or times when a person shall be permitted to receive cash or Common Stock pursuant to a Stock Award; (E) the number of shares of Common Stock with 

1

 

respect
to which a Stock Award shall be granted to each such person; and (F) the Fair Market Value applicable to a Stock Award. 

         (ii)  To construe and interpret the Plan and Awards granted under it, and to establish, amend and revoke rules and regulations
for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan or in any Stock Award Agreement or in the written terms of a Performance
Cash Award, in a manner and to the extent it shall deem necessary or expedient to make the Plan or Award fully effective. 

       (iii)  To settle all controversies regarding the Plan and Awards granted under it. 

        (iv)  To accelerate the time at which an Award may first be exercised or the time during which an Award or any part thereof
will vest in accordance with the Plan, notwithstanding the provisions in the Award stating the time at which it may first be exercised or the time during which it will vest. 

         (v)  To suspend or terminate the Plan at any time. Suspension or termination of the Plan shall not impair rights and
obligations under any Award granted while the Plan is in effect except with the written consent of the affected Participant. 

        (vi)  To amend the Plan in any respect the Board deems necessary or advisable, including, without limitation, by adopting
amendments relating to Incentive Stock Options and certain nonqualified deferred compensation under Section 409A of the Code and/or to bring the Plan or Awards granted under the Plan into
compliance therewith, subject to the limitations, if any of applicable law. However, except as provided in Section 9(a) relating to Capitalization Adjustments, to the extent required by
applicable law or listing requirements, stockholder approval shall be required for any amendment of the Plan that either (A) materially increases the number of shares of Common Stock available
for issuance under the Plan, (B) materially expands the class of individuals eligible to receive Awards under the Plan, (C) materially increases the benefits accruing to Participants
under the Plan or materially reduces the price at which shares of Common Stock may be issued or purchased under the Plan, (D) materially extends the term of the Plan, or (E) expands the
types of Awards available for issuance under the Plan. Except as provided above, rights under any Award granted before amendment of the Plan shall not be impaired by any amendment of the Plan unless
(1) the Company requests the consent of the affected Participant, and (2) such Participant consents in writing. 

       (vii)  To submit any amendment to the Plan for stockholder approval, including, but not limited to, amendments to the Plan
intended to satisfy the requirements of (A) Section 162(m) of the Code regarding the exclusion of performance-based compensation from the limit on corporate deductibility of compensation
paid to Covered Employees, (B) Section 422 of the Code regarding "incentive stock options" or (C) Rule 16b-3. 

      (viii)  To approve forms of Award Agreements for use under the Plan and to amend the terms of any one or more Awards,
including, but not limited to, amendments to provide terms more favorable to the Participant than previously provided in the Award Agreement, subject to any specified limits in the Plan that are not
subject to Board discretion; provided however, that except with respect to amendments that disqualify or impair the status of an Incentive Stock Option,
a Participant's rights under any Award shall not be impaired by any such amendment unless (A) the Company requests the consent of the affected Participant, and (B) such Participant
consents in writing. Notwithstanding the foregoing, subject to the limitations of applicable law, if any, the Board may amend the terms of any one or more Awards without the affected Participant's
consent if necessary to maintain the qualified status of the Award as an Incentive Stock Option or to bring the Award into compliance with Section 409A of the Code.

        (ix)  Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the
best interests of the Company and that are not in conflict with the provisions of the Plan or Awards. 

         (x)  To adopt such procedures and sub-plans as are necessary or appropriate to permit participation in the Plan by
Employees, Directors or Consultants who are foreign nationals or employed outside the United States. 

        (xi)  To effect, at any time and from time to time, with the consent of any adversely affected Participant, (A) the
reduction of the exercise price (or strike price) of any outstanding Option or SAR under the Plan; (B) the cancellation of any outstanding Option or SAR under the Plan and the grant in
substitution therefor of (1) a new Option or SAR under the Plan or another equity plan of the Company covering the same or a different number of shares of Common Stock, (2) a Restricted
Stock Award, (3) a Restricted Stock Unit Award, (4) an Other Stock Award, (5) cash and/or (6) other valuable consideration (as determined by the Board, in its sole
discretion); or (C) any other action that is treated as a repricing under generally accepted accounting principles. 

        (c)    Delegation to Committee.    

          (i)  General.    The Board may delegate some or all of the administration of the Plan to a Committee or Committees.
If administration of the Plan is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been
delegated to the Committee, including the power to delegate to a subcommittee of the Committee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to
the Board shall thereafter be to the Committee or subcommittee), subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the
Board. The Committee may, at any time, abolish the subcommittee and/or revest in the Committee any powers delegated to the subcommittee. The Board may retain the authority to concurrently administer
the Plan with the Committee and may, at any time, revest in the Board some or all of the powers previously delegated. 

         (ii)  Section 162(m) and Rule 16b-3 Compliance.    The Committee may consist solely of two
or more Outside Directors, in accordance with Section 162(m) of the Code, or solely of two or more Non-Employee Directors, in accordance with Rule 16b-3. 

        (d)    Delegation to an Officer.    The Board may delegate to one (1) or more Officers the authority to do one
or both of the following (i) designate Employees who are providing Continuous Service to the Company or any of its Subsidiaries who are not Officers to be recipients of Options and Stock
Appreciation Rights (and, to the extent permitted by applicable law, other Stock Awards) and the terms thereof, and (ii) determine the number of shares of Common Stock to be subject to such
Stock Awards granted to such Employees; provided, however, that the Board resolutions regarding such delegation shall specify the total number of shares
of Common Stock that may be subject to the Stock Awards granted by such Officer and that such Officer may not grant a Stock Award to himself or herself. Notwithstanding the foregoing, the Board may
not delegate authority to an Officer to determine the Fair Market Value pursuant to Section 13(w)(iii) below. 

        (e)    Effect of Board's Decision.    All determinations, interpretations and constructions made by the Board in good
faith shall not be subject to review by any person and shall be final, binding and conclusive on all persons. 

3

 

        3.    SHARES SUBJECT TO THE PLAN.    

        (a)    Share Reserve.    Subject to Section 9(a) relating to Capitalization Adjustments, the aggregate number
of shares of Common Stock that may be issued pursuant to Stock Awards from and after the Effective
Date shall not exceed 8,385,000 shares (the "Share Reserve"), which number is the sum of (i) 6,850,000 new shares, plus (ii) an additional
number of shares in an amount not to exceed 1,535,000 shares (which number consists of the Returning Shares, if any, as such shares become available from time to time). In addition, the number of
shares of Common Stock available for issuance under the Plan shall automatically increase on January 1st of each year commencing on January 1, 2012 and ending on
(and including) January 1, 2019, in an amount equal to four percent (4%) of the total number of shares of Common Stock outstanding on December 31st of the preceding
calendar year. Notwithstanding the foregoing, the Board may act prior to the first day of any calendar year, to provide that there shall be no increase in the share reserve for such calendar year or
that the increase in the share reserve for such calendar year shall be a lesser number of shares of Common Stock than would otherwise occur pursuant to the preceding sentence. For clarity, the Share
Reserve in this Section 3(a) is a limitation on the number of shares of Common Stock that may be issued pursuant to the Plan and does not limit the granting of Stock Awards except as provided
in Section 7(a). Shares may be issued in connection with a merger or acquisition as permitted by, as applicable, NASDAQ Listing Rule 5635(c) or, if applicable, NYSE Listed Company Manual
Section 303A.08, AMEX Company Guide Section 711 or other applicable rule, and such issuance shall not reduce the number of shares available for issuance under the Plan. Furthermore, if a
Stock Award or any portion thereof (i) expires or otherwise terminates without all of the shares covered by such Stock Award having been issued or (ii) is settled in cash
(i.e., the Participant receives cash rather than stock), such expiration, termination or settlement shall not reduce (or otherwise offset) the number of
shares of Common Stock that may be available for issuance under the Plan. 

        (b)    Reversion of Shares to the Share Reserve.    If any shares of Common Stock issued pursuant to a Stock Award are
forfeited back to or repurchased by the Company because of the failure to meet a contingency or condition required to vest such shares in the Participant, then the shares that are forfeited or
repurchased shall revert to and again become available for issuance under the Plan. Any shares reacquired by the Company pursuant to Section 8(g) or as consideration for the exercise of an
Option shall again become available for issuance under the Plan. 

        (c)    Incentive Stock Option Limit.    Notwithstanding anything to the contrary in this Section 3 and, subject
to the provisions of Section 9(a) relating to Capitalization Adjustments, the aggregate maximum number of shares of Common Stock that may be issued pursuant to the exercise of Incentive Stock
Options shall be 8,385,000 shares of Common Stock. 

        (d)    Section 162(m) Limitation on Annual Grants.    Subject to the provisions of Section 9(a) relating
to Capitalization Adjustments, at such time as the Company may be subject to the applicable provisions of Section 162(m) of the Code, a maximum of 6,708,000 shares of Common Stock subject to
Options, Stock Appreciation Rights and Other Stock Awards whose value is determined by reference to an increase over an exercise or strike price of at least one hundred percent (100%) of the Fair
Market Value on the date any such Stock Award is granted may be granted to any Participant during any calendar year. Notwithstanding the foregoing, if any additional Options, Stock Appreciation Rights
or Other Stock Awards whose value is determined by reference to an increase over an exercise or strike price of at least one hundred percent (100%) of the Fair Market Value on the date the Stock Award
are granted to any Participant during any calendar year, compensation attributable to the exercise of such additional Stock Awards shall not satisfy the requirements to be considered "qualified
performance-based compensation" under Section 162(m) of the Code unless such additional Stock Award is approved by the Company's stockholders. 

4

 

        (e)    Source of Shares.    The stock issuable under the Plan shall be shares of authorized but unissued or reacquired
Common Stock, including shares repurchased by the Company on the open market or otherwise. 

        4.    ELIGIBILITY.    

        (a)    Eligibility for Specific Stock Awards.    Incentive Stock Options may be granted only to employees of the
Company or a "parent corporation" or "subsidiary corporation" thereof (as such terms are defined in Sections 424(e) and (f) of the Code). Stock Awards other than Incentive Stock Options
may be granted to Employees, Directors and Consultants; provided, however, Nonstatutory Stock Options and SARs may not be granted to Employees,
Directors and Consultants who are providing Continuous Service only to any "parent" of the Company, as such term is defined in Rule 405 promulgated under the Securities Act, unless the stock
underlying such Stock Awards is treated as "service recipient stock" under Section 409A of the Code because the Stock Awards are granted pursuant to a corporate transaction (such as a spin off
transaction) or unless such Stock Awards comply with the distribution requirements of Section 409A of the Code. 

        (b)    Ten Percent Stockholders.    A Ten Percent Stockholder shall not be granted an Incentive Stock Option unless
the exercise price of such Option is at least one hundred ten percent (110%) of the Fair Market Value on the date of grant and the Option is not exercisable after the expiration of five
(5) years from the date of grant. 

        5.    PROVISIONS RELATING TO OPTIONS AND STOCK APPRECIATION RIGHTS.    

        Each
Option or SAR shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. All Options shall be separately designated Incentive Stock
Options or Nonstatutory Stock Options at the time of grant, and, if certificates are issued, a separate certificate or certificates shall be issued for shares of Common Stock purchased on exercise of
each type of Option. If an Option is not specifically designated as an Incentive Stock Option, then the Option shall be a Nonstatutory Stock Option. The provisions of separate Options or SARs need not
be identical; provided, however, that each Option Agreement or Stock Appreciation Right Agreement shall conform to (through incorporation of provisions
hereof by reference in the applicable Award Agreement or otherwise) the substance of each of the following provisions: 

        (a)    Term.    Subject to the provisions of Section 4(b) regarding Ten Percent Stockholders, no Option or SAR
shall be exercisable after the expiration of ten (10) years from the date of its grant or such shorter period specified in the Award Agreement. 

        (b)    Exercise Price.    Subject to the provisions of Section 4(b) regarding Ten Percent Stockholders, the
exercise price (or strike price) of each Option or SAR shall be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option or SAR on the date the
Option or SAR is granted. Notwithstanding the foregoing, an Option or SAR may be granted with an exercise price (or strike price) lower than one hundred percent (100%) of the Fair Market Value of the
Common Stock subject to the Option or SAR if such Option or SAR is granted pursuant to an assumption of or substitution for another option or stock appreciation right pursuant to a Corporate
Transaction and in a manner consistent with the provisions of Sections 409A and, if applicable, 424(a) of the Code. Each SAR will be denominated in shares of Common Stock equivalents. 

        (c)    Purchase Price for Options.    The purchase price of Common Stock acquired pursuant to the exercise of an
Option shall be paid, to the extent permitted by applicable law and as determined by the Board in its sole discretion, by any combination of the methods of payment set forth below. The Board shall
have the authority to grant Options that do not permit all of the following methods of payment (or otherwise restrict the ability to use certain methods) and to grant Options that require the consent 

5

 

of
the Company to utilize a particular method of payment. The permitted methods of payment are as follows: 

          (i)  by cash, check, bank draft or money order payable to the Company; 

         (ii)  pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the
issuance of the stock subject to the Option, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the
Company from the sales proceeds; 

       (iii)  by delivery to the Company (either by actual delivery or attestation) of shares of Common Stock; 

        (iv)  if the option is a Nonstatutory Stock Option, by a "net exercise" arrangement pursuant to which the Company will reduce
the number of shares of Common Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price;  provided, however, that the
Company shall accept a cash or other payment from the Participant to the extent of any remaining balance of the aggregate
exercise price not satisfied by such reduction in the number of whole shares to be issued; provided, further, that shares of Common Stock will no longer
be
subject to an Option and will not be exercisable thereafter to the extent that (A) shares issuable upon exercise are reduced to pay the exercise price pursuant to the "net exercise,"
(B) shares are delivered to the Participant as a result of such exercise, and (C) shares are withheld to satisfy tax withholding obligations; or 

         (v)  in any other form of legal consideration that may be acceptable to the Board. 

        (d)    Exercise and Payment of a SAR.    To exercise any outstanding Stock Appreciation Right, the Participant must
provide written notice of exercise to the Company in compliance with the provisions of the Stock Appreciation Right Agreement evidencing such Stock Appreciation Right. The appreciation distribution
payable on the exercise of a Stock Appreciation Right will be not greater than an amount equal to the excess of (A) the aggregate Fair Market Value (on the date of the exercise of the Stock
Appreciation Right) of a number of shares of Common Stock equal to the number of Common Stock equivalents in which the Participant is vested under such Stock Appreciation Right, and with respect to
which the Participant is exercising the Stock Appreciation Right on such date, over (B) the strike price that will be determined by the Board at the time of grant of the Stock Appreciation
Right. The appreciation distribution in respect to a Stock Appreciation Right may be paid in Common Stock, in cash, in any combination of the two or in any other form of consideration, as determined
by the Board and contained in the Stock Appreciation Right Agreement evidencing such Stock Appreciation Right. 

        (e)    Transferability of Options and SARs.    The Board may, in its sole discretion, impose such limitations on the
transferability of Options and SARs as the Board shall determine. In the absence of such a determination by the Board to the contrary, the following restrictions on the transferability of Options and
SARs shall apply: 

          (i)  Restrictions on Transfer.    An Option or SAR shall not be transferable except by will or by the laws of
descent and distribution and shall be exercisable during the lifetime of the Participant only by the Participant; provided, however, that the Board may,
in its sole discretion, permit transfer of the Option or SAR in a manner that is not prohibited by applicable tax and securities laws upon the Participant's request. Except as explicitly provided
herein, neither an Option nor a SAR may be transferred for consideration. 

6

 

 

         (ii)  Domestic Relations Orders.    Notwithstanding the foregoing, an Option or SAR may be transferred pursuant to a
domestic relations order; provided, however, that if an Option is an Incentive Stock Option, such Option may be deemed to be a Nonstatutory Stock Option
as a result of such transfer. 

       (iii)  Beneficiary Designation.    Notwithstanding the foregoing, the Participant may, by delivering written notice
to the Company, in a form provided by or otherwise satisfactory to the Company and any broker designated by the Company to effect Option exercises, designate a third party who, in the event of the
death of the Participant, shall thereafter be entitled to exercise the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. In the absence of such a
designation, the executor or administrator of the Participant's estate shall be entitled to exercise the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. 

        (f)    Vesting Generally.    The total number of shares of Common Stock subject to an Option or SAR may vest and
therefore become exercisable in periodic installments that may or may not be equal. The Option or SAR may be subject to such other terms and conditions on the time or times when it may or may not be
exercised (which may be based on the satisfaction of Performance Goals or other criteria) as the Board may deem appropriate. The vesting provisions of individual Options or SARs may vary. The
provisions of this Section 5(f) are subject to any Option or SAR provisions governing the minimum number of shares of Common Stock as to which an Option or SAR may be exercised. 

        (g)    Termination of Continuous Service.    Except as otherwise provided in the applicable Award Agreement or other
agreement between the Participant and the Company, if a Participant's Continuous Service terminates (other than for Cause or upon the Participant's death or Disability), the Participant may exercise
his or her Option or SAR (to the extent that the Participant was entitled to exercise such Award as of the date of termination of Continuous Service) but only within such period of time ending on the
earlier of (i) the date three (3) months following the termination of the Participant's Continuous Service (or such longer or shorter period specified in the applicable Award Agreement),
or (ii) the expiration of the term of the Option or SAR as set forth in the Award Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or
SAR within the time specified herein or in the Award Agreement (as applicable), the Option or SAR shall terminate. 

        (h)    Extension of Termination Date.    If the exercise of an Option or SAR following the termination of the
Participant's Continuous Service (other than for Cause or upon the Participant's death or Disability) would be prohibited at any time solely because the issuance of shares of Common Stock would
violate the registration requirements under the Securities Act, then the Option or SAR shall terminate on the earlier of (i) the expiration of a total period of three (3) months (that
need not be consecutive) after the termination of the Participant's Continuous Service during which the exercise of the Option or SAR would not be in violation of such registration requirements, or
(ii) the expiration of the term of the Option or SAR as set forth in the applicable Award Agreement. In addition, unless otherwise provided in a Participant's Award Agreement, if the sale of
any Common Stock received upon exercise of an Option or SAR following the termination of the Participant's Continuous Service (other than for Cause) would violate the Company's insider trading policy,
then the Option or SAR shall terminate on the earlier of (i) the expiration of a period equal to the applicable post-termination exercise period after the termination of the
Participant's Continuous Service during which the sale of the Common Stock received upon exercise of the Option or SAR would not be in violation of the Company's insider trading policy, or
(ii) the expiration of the term of the Option or SAR as set forth in the applicable Award Agreement. 

        (i)    Disability of Participant.    Except as otherwise provided in the applicable Award Agreement or other agreement
between the Participant and the Company, if a Participant's Continuous Service terminates as a result of the Participant's Disability, the Participant may exercise his or her Option or 

7

 

SAR
(to the extent that the Participant was entitled to exercise such Option or SAR as of the date of termination of Continuous Service), but only within such period of time ending on the earlier of
(i) the date twelve (12) months following such termination of Continuous Service (or such longer or shorter period specified in the Award Agreement), or (ii) the expiration of the
term of the Option or SAR as set forth in the Award Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or SAR within the time specified herein
or in the Award Agreement (as applicable), the Option or SAR (as applicable) shall terminate. 

        (j)    Death of Participant.    Except as otherwise provided in the applicable Award Agreement or other agreement
between the Participant and the Company, if (i) a Participant's Continuous Service terminates as a result of the Participant's death, or (ii) the Participant dies within the period (if
any) specified in the Award Agreement for exercisability after the termination of the Participant's Continuous Service (for a reason other than death), then the Option or SAR may be exercised (to the
extent the Participant was entitled to exercise such Option or SAR as of the date of death) by the Participant's estate, by a person who acquired the right to exercise the Option or SAR by bequest or
inheritance or by a person designated to exercise the Option or SAR upon the Participant's death, but only within the period ending on the earlier of (i) the date eighteen (18) months
following the date of death (or such longer or shorter period specified in the Award Agreement), or (ii) the expiration of the term of such Option or SAR as set forth in the Award Agreement.
If, after the Participant's death, the Option or SAR is not exercised within the time specified herein or in the Award Agreement (as applicable), the Option or SAR shall terminate. 

        (k)    Termination for Cause.    Except as explicitly provided otherwise in a Participant's Award Agreement or other
individual written agreement between the Company or any Affiliate and the Participant, if a Participant's Continuous Service is terminated for Cause, the Option or SAR shall terminate immediately upon
such Participant's termination of Continuous Service , and the Participant shall be prohibited from exercising his or her Option or SAR from and after the time of such termination of Continuous
Service. 

        (l)    Non-Exempt Employees.    No Option or SAR, whether or not vested, granted to an Employee who is a
non-exempt employee for purposes of the Fair Labor Standards Act of 1938, as amended, shall be first exercisable for any shares of Common Stock until at least six (6) months
following the date of grant of the Option or SAR. Notwithstanding the foregoing, consistent with the provisions of the Worker Economic Opportunity Act, (i) in the event of the Participant's
death or Disability, (ii) upon a Corporate Transaction in which such Option or SAR is not assumed, continued, or substituted, (iii) upon a Change in Control, or (iv) upon the
Participant's retirement (as such term may be defined in the Participant's Award Agreement or in another applicable agreement or in accordance with the Company's then current employment policies and
guidelines), any such vested Options and SARs may be exercised earlier than six months following the date of grant. The foregoing provision is intended to operate so that any income derived by a
non-exempt employee in connection with the exercise or vesting of an Option or SAR will be exempt from his or her regular rate of pay. 

        6.    PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS AND SARS.    

        (a)    Restricted Stock Awards.    Each Restricted Stock Award Agreement shall be in such form and shall contain such
terms and conditions as the Board shall deem appropriate. To the extent consistent with the Company's Bylaws, at the Board's election, shares of Common Stock may be (i) held in book entry form
subject to the Company's instructions until any restrictions relating to the Restricted Stock Award lapse; or (ii) evidenced by a certificate, which certificate shall be held in such form and
manner as determined by the Board. The terms and conditions of Restricted Stock Award Agreements may change from time to time, and the terms and conditions of separate Restricted Stock Award
Agreements need not be identical; provided, however, that each Restricted Stock Award 

8

 

Agreement
shall conform to (through incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions: 

          (i)  Consideration.    A Restricted Stock Award may be awarded in consideration for (A) cash, check, bank
draft or money order payable to the Company, (B) past services to the Company or an Affiliate, or (C) any other form of legal consideration (including future services) that may be
acceptable to the Board, in its sole discretion, and permissible under applicable law. 

         (ii)  Vesting.    Shares of Common Stock awarded under the Restricted Stock Award Agreement may be subject to
forfeiture to the Company in accordance with a vesting schedule to be determined by the Board. 

       (iii)  Termination of Participant's Continuous Service.    If a Participant's Continuous Service terminates, the
Company may receive through a forfeiture condition or a repurchase right any or all of the shares of Common Stock held by the Participant that have not vested as of the date of termination of
Continuous Service under the terms of the Restricted Stock Award Agreement. 

        (iv)  Transferability.    Rights to acquire shares of Common Stock under the Restricted Stock Award Agreement shall
be transferable by the Participant only upon such terms and conditions as are set forth in the Restricted Stock Award Agreement, as the Board shall determine in its sole discretion, so long as Common
Stock awarded under the Restricted Stock Award Agreement remains subject to the terms of the Restricted Stock Award Agreement. 

         (v)  Dividends.    A Restricted Stock Award Agreement may provide that any dividends paid on Restricted Stock will
be subject to the same vesting and forfeiture restrictions as apply to the shares subject to the Restricted Stock Award to which they relate. 

        (b)    Restricted Stock Unit Awards.    Each Restricted Stock Unit Award Agreement shall be in such form and shall
contain such terms and conditions as the Board shall deem appropriate. The terms and conditions of Restricted Stock Unit Award Agreements may change from time to time, and the terms and conditions of
separate Restricted Stock Unit Award Agreements need not be identical; provided, however, that each Restricted Stock Unit Award Agreement shall conform
to (through incorporation of the provisions hereof by reference in the Agreement or otherwise) the substance of each of the following provisions: 

          (i)  Consideration.    At the time of grant of a Restricted Stock Unit Award, the Board will determine the
consideration, if any, to be paid by the Participant upon delivery of each share of Common Stock subject to the Restricted Stock Unit Award. The consideration to be paid (if any) by the Participant
for each share of Common Stock subject to a Restricted Stock Unit Award may be paid in any form of legal consideration that may be acceptable to the Board, in its sole discretion, and permissible
under applicable law. 

         (ii)  Vesting.    At the time of the grant of a Restricted Stock Unit Award, the Board may impose such restrictions
on or conditions to the vesting of the Restricted Stock Unit Award as it, in its sole discretion, deems appropriate. 

       (iii)  Payment.    A Restricted Stock Unit Award may be settled by the delivery of shares of Common Stock, their
cash equivalent, any combination thereof or in any other form of consideration, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. 

        (iv)  Additional Restrictions.    At the time of the grant of a Restricted Stock Unit Award, the Board, as it deems
appropriate, may impose such restrictions or conditions that delay the delivery of the shares of Common Stock (or their cash equivalent) subject to a Restricted Stock Unit Award to a time after the
vesting of such Restricted Stock Unit Award. 

9

 

         (v)  Dividend Equivalents.    Dividend equivalents may be credited in respect of shares of Common Stock covered by a
Restricted Stock Unit Award, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. At the sole discretion of the Board, such dividend equivalents may be converted into
additional shares of Common Stock covered by the Restricted Stock Unit Award in such manner as determined by the Board. Any additional shares covered by the Restricted Stock Unit Award credited by
reason of such dividend equivalents will be subject to all of the same terms and conditions of the underlying Restricted Stock Unit Award Agreement to which they relate. 

        (vi)  Termination of Participant's Continuous Service.    Except as otherwise provided in the applicable Restricted
Stock Unit Award Agreement, such portion of the Restricted Stock Unit Award that has not vested will be forfeited upon the Participant's termination of Continuous Service. 

        (c)    Performance Awards.    

          (i)  Performance Stock Awards.    A Performance Stock Award is a Stock Award that may vest or may be exercised
contingent upon the attainment during a Performance Period of certain Performance Goals. A Performance Stock Award may, but need not, require the completion of a specified period of Continuous
Service. The length of any Performance Period, the Performance Goals to be achieved during the Performance Period, and the measure of whether and to what degree such Performance Goals have been
attained shall be conclusively determined by the Committee, in its sole discretion. The maximum number of shares covered by an Award that may be granted to any Participant in a calendar year
attributable to Stock Awards described in this Section 6(c)(i) (whether the grant, vesting or exercise is contingent upon the attainment during a Performance Period of the Performance Goals)
shall not exceed five hundred thousand (500,000) shares of Common Stock. The Board may provide for or, subject to such terms and conditions as the Board may specify, may permit a Participant to elect
for, the payment of any Performance Stock Award to be deferred to a specified date or event. In addition, to the extent permitted by applicable law and the applicable Award Agreement, the Board may
determine that cash may be used in payment of Performance Stock Awards. 

         (ii)  Performance Cash Awards.    A Performance Cash Award is a cash award that may be paid contingent upon the
attainment during a Performance Period of certain Performance Goals. A Performance Cash Award may also require the completion of a specified period of Continuous Service. At the time of grant of a
Performance Cash Award, the length of any Performance Period, the Performance Goals to be achieved during the Performance Period, and the measure of whether and to what degree such Performance Goals
have been attained shall be conclusively determined by the Committee, in its sole discretion. In any calendar year, the Committee may not grant a Performance Cash Award that has a maximum value that
may be paid to any Participant in excess of three million dollars ($3,000,000). The Board may provide for or, subject to such terms and conditions as the Board may specify, may permit a Participant to
elect for, the payment of any Performance Cash Award to be deferred to a specified date or event. The Committee may specify the form of payment of Performance Cash Awards, which may be cash or other
property, or may provide for a Participant to have the option for his or her Performance Cash Award, or such portion thereof as the Board may specify, to be paid in whole or in part in cash or other
property. 

       (iii)  Board Discretion.    The Board retains the discretion to reduce or eliminate the compensation or economic
benefit due upon attainment of Performance Goals and to define the manner of calculating the Performance Criteria it selects to use for a Performance Period. 

        (iv)  Section 162(m) Compliance.    Unless otherwise permitted in compliance with the requirements of
Section 162(m) of the Code with respect to an Award intended to qualify as "performance-based compensation" thereunder, the Committee shall establish the Performance 

10

 

Goals
applicable to, and the formula for calculating the amount payable under, the Award no later than the earlier of (a) the date ninety (90) days after the commencement of the
applicable Performance Period, or (b) the date on which twenty-five percent (25%) of the Performance Period has elapsed, and in either event at a time when the achievement of the
applicable Performance Goals remains substantially uncertain. Prior to the payment of any compensation under an Award intended to qualify as "performance-based compensation" under
Section 162(m) of the Code, the Committee shall certify the extent to which any Performance Goals and any other material terms under such Award have been satisfied (other than in cases where
such relate solely to the increase in the value of the Common Stock). Notwithstanding satisfaction of any completion of any Performance Goals, to the extent specified at the time of grant of an Award
to "covered employees" within the meaning of Section 162(m) of the Code, the number of shares of Common Stock, Options, cash or other benefits granted, issued, retainable and/or vested under an
Award on account of satisfaction of such Performance Goals may be reduced by the Committee on the basis of such further considerations as the Committee, in its sole discretion, shall determine. 

        (d)    Other Stock Awards.    Other forms of Stock Awards valued in whole or in part by reference to, or otherwise
based on, Common Stock, including the appreciation in value thereof (e.g., options or stock rights with an exercise price or strike price less than 100% of the Fair Market Value of the Common
Stock at the time of grant) may be granted either alone or in addition to Stock Awards provided for
under Section 5 and the preceding provisions of this Section 6. Subject to the provisions of the Plan, the Board shall have sole and complete authority to determine the persons to whom
and the time or times at which such Other Stock Awards will be granted, the number of shares of Common Stock (or the cash equivalent thereof) to be granted pursuant to such Other Stock Awards and all
other terms and conditions of such Other Stock Awards. 

        7.    COVENANTS OF THE COMPANY.    

        (a)    Availability of Shares.    During the terms of the Stock Awards, the Company shall keep available at all times
the number of shares of Common Stock reasonably required to satisfy such Stock Awards. 

        (b)    Securities Law Compliance.    The Company shall seek to obtain from each regulatory commission or agency having
jurisdiction over the Plan such authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise of the Stock Awards; provided,
however, that this undertaking shall not require the Company to register under the Securities Act the Plan, any Stock Award or any Common Stock issued or issuable pursuant to
any such Stock Award. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority that counsel for the Company deems necessary for the
lawful issuance and sale of Common Stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell Common Stock upon exercise of such Stock Awards unless and until
such authority is obtained. A Participant shall not be eligible for the grant of a Stock Award or the subsequent issuance of Common Stock pursuant to the Stock Award if such grant or issuance would be
in violation of any applicable securities law. 

        (c)    No Obligation to Notify or Minimize Taxes.    The Company shall have no duty or obligation to any Participant
to advise such holder as to the time or manner of exercising such Stock Award. Furthermore, the Company shall have no duty or obligation to warn or otherwise advise such holder of a pending
termination or expiration of a Stock Award or a possible period in which the Stock Award may not be exercised. The Company has no duty or obligation to minimize the tax consequences of a Stock Award
to the holder of such Stock Award. 

11

 

 
        8.    MISCELLANEOUS.    

        (a)    Use of Proceeds from Sales of Common Stock.    Proceeds from the sale of shares of Common Stock pursuant to
Stock Awards shall constitute general funds of the Company. 

        (b)    Corporate Action Constituting Grant of Stock Awards.    Corporate action constituting a grant by the Company of
a Stock Award to any Participant shall be deemed completed as of the date of such corporate action, unless otherwise determined by the Board, regardless of when the instrument, certificate, or letter
evidencing the Stock Award is communicated to, or actually received or accepted by, the Participant. 

        (c)    Stockholder Rights.    No Participant shall be deemed to be the holder of, or to have any of the rights of a
holder with respect to, any shares of Common Stock subject to such Stock Award unless and until (i) such Participant has satisfied all requirements for exercise of the Stock Award pursuant to
its terms, if applicable, and (ii) the issuance of the Common Stock subject to such Stock Award has been entered into the books and records of the Company. 

        (d)    No Employment or Other Service Rights.    Nothing in the Plan, any Stock Award Agreement or any other
instrument executed thereunder or in connection with any Award granted pursuant thereto shall confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in
effect at the time the Stock Award was granted or shall affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without notice and with or without
cause, (ii) the service of a Consultant pursuant to the terms of such Consultant's agreement with the Company or an Affiliate, or (iii) the service of a Director pursuant to the Bylaws
of the Company or an Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be. 

        (e)    Incentive Stock Option $100,000 Limitation.    To the extent that the aggregate Fair Market Value (determined
at the time of grant) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionholder during any calendar year (under all plans of the Company and
any Affiliates) exceeds one hundred thousand dollars ($100,000), the Options or portions thereof that exceed such limit (according to the order in which they were granted) shall be treated as
Nonstatutory Stock Options, notwithstanding any contrary provision of the applicable Option Agreement(s). 

        (f)    Investment Assurances.    The Company may require a Participant, as a condition of exercising or acquiring
Common Stock under any Stock Award, (i) to give written assurances satisfactory to the Company as to the Participant's knowledge and experience in financial and business matters and/or to
employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or
together with the purchaser representative, the merits and risks of exercising the Stock Award; and (ii) to give written assurances satisfactory to the Company stating that the Participant is
acquiring Common Stock subject to the Stock Award for the Participant's own account and not with any present intention of selling or otherwise distributing the Common Stock. The foregoing
requirements, and any assurances given pursuant to such requirements, shall be inoperative if (A) the issuance of the shares upon the exercise or acquisition of Common Stock under the Stock
Award has been registered under a then currently effective registration statement under the Securities Act, or (B) as to any particular requirement, a determination is made by counsel for the
Company that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock
certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of
the Common Stock. 

        (g)    Withholding Obligations.    Unless prohibited by the terms of a Stock Award Agreement, the Company may, in its
sole discretion, satisfy any federal, state or local tax withholding obligation relating to an Award by any of the following means or by a combination of such means: (i) causing the 

12

 

Participant
to tender a cash payment; (ii) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to the Participant in connection with the Award;  provided, however,
that no shares of Common Stock are withheld with a value exceeding the minimum amount of tax required to be withheld by law (or such
lesser amount as may be necessary to avoid classification of the Stock Award as a liability for financial accounting purposes); (iii) withholding cash from an Award settled in cash;
(iv) withholding payment from any amounts otherwise payable to the Participant; or (v) by such other method as may be set forth in the Award Agreement. 

        (h)    Electronic Delivery.    Any reference herein to a "written" agreement or document shall include any agreement
or document delivered electronically, filed publicly at www.sec.gov (or any successor website thereto) or posted on the Company's intranet. 

        (i)    Deferrals.    To the extent permitted by applicable law, the Board, in its sole discretion, may determine that
the delivery of Common Stock or the payment of cash, upon the exercise, vesting or settlement of all or a portion of any Award may be deferred and may establish programs and procedures for deferral
elections to be made by Participants. Deferrals by Participants will be made in accordance with Section 409A of the Code. Consistent with Section 409A of the Code, the Board may provide
for distributions while a Participant is still an employee or otherwise providing services to the Company. The Board is authorized to make deferrals of Awards and determine when, and in what annual
percentages, Participants may receive payments, including lump sum payments, following the Participant's termination of Continuous Service, and implement such other terms and conditions consistent
with the provisions of the Plan and in accordance with applicable law. 

        (j)    Compliance with Section 409A.    To the extent that the Board determines that any Award granted
hereunder is subject to Section 409A of the Code, the Award Agreement evidencing such Award shall incorporate the terms and conditions necessary to avoid the consequences specified in
Section 409A(a)(1) of the Code. To the extent applicable, the Plan and Award Agreements shall be interpreted in accordance with Section 409A of the Code. Notwithstanding anything to the
contrary in this Plan (and unless the Award Agreement specifically provides otherwise), if the shares of Common Stock are publicly traded and a Participant holding an Award that constitutes "deferred
compensation" under Section 409A of the Code is a "specified employee" for purposes of Section 409A of the Code, no distribution or payment of any amount shall be made upon a "separation
from service" before a date that is six (6) months following the date of such Participant's "separation from service" (as defined in Section 409A of the Code without regard to
alternative definitions thereunder) or, if earlier, the date of the Participant's death, unless such distribution or payment can be made in a manner that complies with Section 409A of the Code. 

        9.    ADJUSTMENTS UPON CHANGES IN COMMON STOCK; OTHER CORPORATE EVENTS.    

        (a)    Capitalization Adjustments.    In the event of a Capitalization Adjustment, the Board shall appropriately and
proportionately adjust: (i) the class(es) and maximum number of securities subject to the Plan pursuant to Section 3(a), (ii) the class(es) and maximum number of securities that
may be issued pursuant to the exercise of Incentive Stock Options pursuant to Section 3(c), (iii) the class(es) and maximum number of securities that may be awarded to any person
pursuant to Sections 3(d) and 6(c)(i) , and (iv) the class(es) and number of securities and price per share of stock subject to outstanding Stock Awards. The Board shall make such
adjustments, and its determination shall be final, binding and conclusive. 

        (b)    Dissolution or Liquidation.    Except as otherwise provided in the Stock Award Agreement, in the event of a
dissolution or liquidation of the Company, all outstanding Stock Awards (other than Stock Awards consisting of vested and outstanding shares of Common Stock not subject to a forfeiture condition or
the Company's right of repurchase) shall terminate immediately prior to the completion of such dissolution or liquidation, and the shares of Common Stock subject to the Company's repurchase rights or
subject to a forfeiture condition may be repurchased or reacquired by the Company notwithstanding the fact that the holder of such Stock Award is providing Continuous Service,  provided,  

13

 

 however, that the Board may, in its sole discretion, cause some or all Stock Awards to become fully vested, exercisable and/or no longer subject to repurchase or forfeiture (to
the extent such Stock Awards have not previously expired or terminated) before the dissolution or liquidation is completed but contingent on its completion. 

        (c)    Corporate Transaction.    The following provisions shall apply to Stock Awards in the event of a Corporate
Transaction unless otherwise provided in the instrument evidencing the Stock Award or any other written agreement between the Company or any Affiliate and the Participant or unless otherwise expressly
provided by the Board at the time of grant of a Stock Award. 

          (i)  Stock Awards May Be Assumed.    In the event of a Corporate Transaction, any surviving corporation or
acquiring corporation (or the surviving or acquiring corporation's parent company) may assume or continue any or all Stock Awards outstanding under the Plan or may substitute similar stock awards for
Stock Awards outstanding under the Plan (including but not limited to, awards to acquire the same consideration paid to the stockholders of the Company pursuant to the Corporate Transaction), and any
reacquisition or repurchase rights held by the Company in respect of Common Stock issued pursuant to Stock Awards may be assigned by the Company to the successor of the Company (or the successor's
parent company, if any), in connection with such Corporate Transaction. A surviving corporation or acquiring corporation (or its parent) may choose to assume or continue only a portion of a Stock
Award or substitute a similar stock award for only a portion of a Stock Award, or may choose to assume or continue the Stock Awards held by some, but not all Participants. The terms of any assumption,
continuation or substitution shall be set by the Board. 

         (ii)  Stock Awards Held by Current Participants.    In the event of a Corporate Transaction in which the surviving
corporation or acquiring corporation (or its parent company) does not assume or continue such outstanding Stock Awards or substitute similar stock awards for such outstanding Stock Awards, then with
respect to Stock Awards that have not been assumed, continued or substituted and that are held by Participants whose Continuous Service has not terminated prior to the effective time of the Corporate
Transaction (referred to as the "Current Participants"), the vesting of such Stock Awards (and, with respect to Options and Stock Appreciation Rights,
the time when such Stock Awards may be exercised) shall be accelerated in full to a date prior to the effective time of such Corporate Transaction (contingent upon the effectiveness of the Corporate
Transaction) as the Board shall determine (or, if the Board shall not determine such a date, to the date that is five (5) days prior to the effective time of the Corporate Transaction), and
such Stock Awards shall terminate if not exercised (if applicable) at or prior to the effective time of the Corporate Transaction, and any reacquisition or
repurchase rights held by the Company with respect to such Stock Awards shall lapse (contingent upon the effectiveness of the Corporate Transaction). 

       (iii)  Stock Awards Held by Persons other than Current Participants.    In the event of a Corporate Transaction in
which the surviving corporation or acquiring corporation (or its parent company) does not assume or continue such outstanding Stock Awards or substitute similar stock awards for such outstanding Stock
Awards, then with respect to Stock Awards that have not been assumed, continued or substituted and that are held by persons other than Current Participants, such Stock Awards shall terminate if not
exercised (if applicable) prior to the effective time of the Corporate Transaction; provided, however, that any reacquisition or repurchase rights held
by the Company with respect to such Stock Awards shall not terminate and may continue to be exercised notwithstanding the Corporate Transaction. 

        (iv)  Payment for Stock Awards in Lieu of Exercise.    Notwithstanding the foregoing, in the event a Stock Award
will terminate if not exercised prior to the effective time of a Corporate Transaction, the Board may provide, in its sole discretion, that the holder of such Stock Award may not exercise such Stock
Award but will receive a payment, in such form as may be determined 

14

 

by
the Board, equal in value, at the effective time, to the excess, if any, of (A) the value of the property the Participant would have received upon the exercise of the Stock Award (including,
at the discretion of the Board, any unvested portion of such Stock Award), over (B) any exercise price payable by such holder in connection with such exercise. 

        (d)    Change in Control.    A Stock Award may be subject to additional acceleration of vesting and exercisability
upon or after a Change in Control as may be provided in the Stock Award Agreement for such Stock Award or as may be provided in any other written agreement between the Company or any Affiliate and the
Participant, but in the absence of such provision, no such acceleration shall occur. 

        10.    TERMINATION OR SUSPENSION OF THE PLAN.    

        (a)    Plan Term.    The Board may suspend or terminate the Plan at any time. Unless terminated sooner by the Board,
the Plan shall automatically terminate on the day before the tenth (10th) anniversary of the earlier of (i) the date the Plan is adopted by the Board, or (ii) the date the Plan is
approved by the stockholders of the Company. No Awards may be granted under the Plan while the Plan is suspended or after it is terminated. 

        (b)    No Impairment of Rights.    Suspension or termination of the Plan shall not impair rights and obligations under
any Award granted while the Plan is in effect except with the written consent of the affected Participant. 

        11.    EFFECTIVE DATE OF PLAN.    

        This
Plan shall become effective on the Effective Date. 

        12.    CHOICE OF LAW.    The laws of the State of Iowa shall govern all questions concerning
the construction, validity and interpretation of this Plan, without regard to that state's conflict of laws rules.

capitalized terms indicated below: 

        (a)   "Affiliate" means, at the time of determination, any "parent" or

        (f)    "Cause" shall have the meaning ascribed to such term in any written
agreement between the Participant and the Company defining such term and, in the absence of such agreement, such term shall mean, with respect to a Participant, the occurrence of any of the following

shall have no effect upon any determination of the rights or obligations of the Company or such Participant for any other purpose. 

        (g)   "Change in Control" means the occurrence, in a single transaction or in a
series of related transactions, of any one or more of the following events: 

          (i)  any Exchange Act Person becomes the Owner, directly or indirectly, of securities of the Company representing more than
fifty percent (50%) of the combined voting power of the Company's then outstanding securities other than by virtue of a merger, consolidation or similar transaction. Notwithstanding the foregoing, a
Change in Control shall not be deemed to occur (A) on account of the acquisition of securities of the Company directly from the Company, (B) on account of the acquisition of securities
of the Company by an investor, any affiliate thereof or any other Exchange Act Person that acquires the Company's securities in a transaction or series of related transactions the primary purpose of
which is to obtain financing for the Company through the issuance of equity securities, or (C) solely because the level of Ownership held by any Exchange Act Person (the
"Subject Person") exceeds the designated percentage threshold of the outstanding voting securities as a result of a repurchase or other acquisition of
voting securities by the Company reducing the number of shares outstanding, provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition of
voting securities by the Company, and after such share acquisition, the Subject Person becomes the Owner of any additional voting securities that, assuming the repurchase or other acquisition had not
occurred, increases the percentage of the then outstanding voting securities Owned by the Subject Person over the designated percentage threshold, then a Change in Control shall be deemed to occur; 

         (ii)  there is consummated a merger, consolidation or similar transaction involving (directly or indirectly) the Company and,
immediately after the consummation of such merger, consolidation or similar transaction, the stockholders of the Company immediately prior thereto do not Own, directly or indirectly, either

transaction or (B) more than fifty percent (50%) of the combined outstanding voting power of the
parent of the surviving Entity in such merger, consolidation or similar transaction, in each case in substantially the same proportions as their Ownership of the outstanding voting securities of the
Company immediately prior to such transaction; 

       (iii)  the stockholders of the Company approve or the Board approves a plan of complete dissolution or liquidation of the
Company, or a complete dissolution or liquidation of the Company shall otherwise occur, except for a liquidation into a parent corporation; 

        (iv)  there is consummated a sale, lease, exclusive license or other disposition of all or substantially all of the
consolidated assets of the Company and its Subsidiaries, other than a sale, lease, license or other disposition of all or substantially all of the consolidated assets of the Company and its
Subsidiaries to an Entity, more than fifty percent (50%) of the combined voting power of the voting securities of which are Owned by stockholders of the Company in substantially the same proportions

however, that if the appointment or election (or nomination for election) of any new Board member was approved or recommended by a majority vote of the members of the Incumbent
Board then still in office, such new member shall, for purposes of this Plan, be considered as a member of the Incumbent Board. 

        Notwithstanding
the foregoing or any other provision of this Plan, (A) the term Change in Control shall not include a sale of assets, merger or other transaction effected
exclusively for the purpose of changing the domicile of the Company, and (B) the definition of Change in Control (or any analogous term) in an individual written agreement between the Company
or any Affiliate and the Participant shall supersede the foregoing definition with respect to Awards subject to such agreement; provided, however, that
if no definition of Change in Control or any analogous term is set forth in such an individual written agreement, the foregoing definition shall apply.

Affiliate and is compensated for such services. However, service solely as a Director, or payment of a fee for such service, shall not cause a Director to be considered a "Consultant" for purposes of
the Plan. Notwithstanding the foregoing, a person is treated as a Consultant under this Plan only if a Form S-8 Registration Statement under the Securities Act is available to
register either the offer or the sale of the Company's securities to such person. 

        (m)  "Continuous Service" means that the Participant's service with the
Company or an Affiliate, whether as an Employee, Director or Consultant, is not interrupted or terminated. A change in the capacity in which the Participant renders service to the Company or an
Affiliate as an Employee, Consultant or Director or a change in the entity for which the Participant renders such service, provided that there is no interruption or termination of the Participant's
service with the Company or an Affiliate, shall not terminate a Participant's Continuous Service; provided, however, if the Entity for which a
Participant is rendering services ceases to qualify as an Affiliate, as determined by the Board, in its sole discretion, such Participant's Continuous Service shall be considered to have terminated on
the date such Entity ceases to qualify as an Affiliate. To the extent permitted by law, the Board or the chief executive officer of the Company, in that party's sole discretion, may determine whether
Continuous Service shall be considered interrupted in the case of (i) any leave of absence approved by the Board or chief executive officer, including sick leave, military leave or any other
personal leave, or (ii) transfers between the Company, an Affiliate, or their successors. Notwithstanding the foregoing, a leave of absence shall be treated as Continuous Service for purposes
of vesting in an Award only to such extent as may be provided in the Company's leave of absence policy, in the written terms of any leave of absence agreement or policy applicable to the Participant,
or as otherwise required by law.

         (ii)  Unless otherwise provided by the Board, if there is no closing sales price for the Common Stock on the date of
