(As Amended and Restated on July 24, 2018)

SECTION 1.  PURPOSE

This International Isotopes Inc. 2015 Incentive Plan is an amendment and restatement of the International Isotopes Inc. 2006 Equity Incentive Plan.  The purpose of the International Isotopes Inc. 2015 Incentive Plan is to attract, retain and motivate employees, officers, directors, consultants, agents, advisors and independent contractors of the Company and its Related Companies by providing them the opportunity to acquire a proprietary interest in the Company and to align their interests and efforts to the long-term interests of the Company’s stockholders.  

SECTION 2.  DEFINITIONS

Certain capitalized terms used in the Plan have the meanings set forth in Appendix A.

SECTION 3.  ADMINISTRATION

3.1

Administration of the Plan

The Plan shall be administered by the Board or the Compensation Committee, which shall be composed of two or more directors, each of whom is a “non-employee director” within the meaning of Rule 16b-3(b)(3) promulgated under the Exchange Act, or any successor definition adopted by the Securities and Exchange Commission, and an “outside director” within the meaning of Section 162(m) of the Code, or any successor provision thereto.  Notwithstanding the foregoing, the Board may delegate responsibility for administering the Plan with respect to designated classes of Eligible Persons to different committees consisting of one or more members of the Board, subject to such limitations as the Board deems appropriate, except with respect to Awards to Participants who are subject to Section 16 of the Exchange Act or Awards granted pursuant to Section 16 of the Plan.  Members of any committee shall serve for such term as the Board may determine, subject to removal by the Board at any time.  To the extent consistent with applicable law, the Board or the Compensation Committee may authorize one or more officers of the Company to grant Awards to designated classes of Eligible Persons, within limits specifically prescribed by the Board or the Compensation Committee; provided, however, that no such officer shall have or obtain authority to grant Awards to himself or herself or to any person subject to Section 16 of the Exchange Act.  All references in the Plan to the “Committee” shall be, as applicable, to the Compensation Committee or any other committee or any officer to whom the Board or the Compensation Committee has delegated authority to administer the Plan.

3.2

Administration and Interpretation by Committee

(a)

Except for the terms and conditions explicitly set forth in the Plan and to the extent permitted by applicable law, the Committee shall have full power and exclusive authority, subject to such orders or resolutions not inconsistent with the provisions of the Plan as may from time to time be adopted by the Board or a Committee composed of members of the Board, to (i) select the Eligible Persons to whom Awards may from time to time be granted under the Plan; (ii) determine the type or types of Award to be granted to each Participant under the Plan; (iii) determine the number of shares of Common Stock to be covered by each Award granted under the Plan; (iv) determine the terms and conditions of any Award granted under the Plan; (v) approve the forms of notice or agreement for use under the Plan; (vi) determine whether, to what extent and under what circumstances Awards may be settled in cash, shares of Common Stock or other property or canceled or suspended; (vii) determine whether, to what extent and under what circumstances cash, shares of Common Stock, other property and other amounts payable with respect to an Award shall be deferred either automatically or at the election of the Participant; (viii) interpret and administer the Plan and any instrument evidencing an Award, notice or agreement executed or entered into under the Plan; (ix) establish such rules and regulations as it shall deem appropriate for the proper administration of

the Plan; (x) delegate ministerial duties to such of the Company’s employees as it so determines; and (xi) make any other determination and take any other action that the Committee deems necessary or desirable for administration of the Plan.

(b)

The Committee shall have the right, without stockholder approval, to (i) cancel or amend outstanding Options or SARs for the purpose of repricing, replacing or regranting such Options or SARs with Options or SARs that have a purchase or grant price that is less than the purchase or grant price for the original Options or SARs except in connection with adjustments provided in Section 15, or (ii) issue an Option or amend an outstanding Option to provide for the grant or issuance of a new Option on exercise of the original Option.

(c)

The effect on the vesting of an Award of a Company-approved leave of absence or a Participant’s working less than full-time shall be determined by the Company’s chief human resources officer or other person performing that function or, with respect to directors or executive officers, by the Compensation Committee, whose determination shall be final.

(d)

Decisions of the Committee shall be final, conclusive and binding on all persons, including the Company, any Participant, any stockholder and any Eligible Person.  A majority of the members of the Committee may determine its actions.

SECTION 4.  SHARES SUBJECT TO THE PLAN

4.1

Authorized Number of Shares

Subject to adjustment from time to time as provided in Section 15.1, the number of shares of Common Stock authorized for issuance under the Plan shall be:

(a)

80,000,000 shares; plus

(b)

11,089,967 shares authorized but not issued under the Company’s 2002 Long-Term Incentive Plan (the “Prior Plan”).

Shares issued under the Plan shall be drawn from authorized and unissued shares or shares now held or subsequently acquired by the Company.

4.2

Share Usage

(a)

Shares of Common Stock covered by an Award shall not be counted as used unless and until they are actually issued and delivered to a Participant.  If any Award lapses, expires, terminates or is canceled prior to the issuance of shares thereunder or if shares of Common Stock are issued under the Plan to a Participant and thereafter are forfeited to or otherwise reacquired by the Company, the shares subject to such Awards and the forfeited or reacquired shares shall again be available for issuance under the Plan.  Any shares of Common Stock (i) tendered by a Participant or retained by the Company as full or partial payment to the Company for the purchase price of an Award or to satisfy tax withholding obligations in connection with an Award, or (ii) covered by an Award that is settled in cash, or in a manner such that some or all of the shares of Common Stock covered by the Award are not issued, shall be available for Awards under the Plan.  The number of shares of Common Stock available for issuance under the Plan shall not be reduced to reflect any dividends or dividend equivalents that are reinvested into additional shares of Common Stock or credited as additional shares of Common Stock subject or paid with respect to an Award.

(b)

The Committee shall also, without limitation, have the authority to grant Awards as an alternative to or as the form of payment for grants or rights earned or due under other compensation plans or arrangements of the Company.

- 2 -

(c)

Notwithstanding anything in the Plan to the contrary, the Committee may grant Substitute Awards under the Plan.  Substitute Awards shall not reduce the number of shares authorized for issuance under the Plan.  In the event that an Acquired Entity has shares available for awards or grants under one or more preexisting plans not adopted in contemplation of such acquisition or combination, then, to the extent determined by the Board or the Compensation Committee, the shares available for grant pursuant to the terms of such preexisting plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to holders of common stock of the entities that are parties to such acquisition or combination) may be used for Awards under the Plan and shall not reduce the number of shares of Common Stock authorized for issuance under the Plan; provided, however, that Awards using such available shares shall not be made after the date awards or grants could have been made under the terms of such preexisting plans, absent the acquisition or combination, and shall only be made to individuals who were not employees or directors of the Company or a Related Company prior to such acquisition or combination.  In the event that a written agreement between the Company and an Acquired Entity pursuant to which a merger or consolidation is completed is approved by the Board and said agreement sets forth the terms and conditions of the substitution for or assumption of outstanding awards of the Acquired Entity, said terms and conditions shall be deemed to be the action of the Committee without any further action by the Committee, except as may be required for compliance with Rule 16b-3 under the Exchange Act, and the persons holding such awards shall be deemed to be Participants.

(d)

Notwithstanding the other provisions in this Section 4.2, the maximum number of shares that may be issued upon the exercise of Incentive Stock Options shall equal the aggregate share number stated in Section 4.1, subject to adjustment as provided in Section 15.1.

SECTION 5.  ELIGIBILITY

An Award may be granted to any employee, officer or director of the Company or a Related Company whom the Committee from time to time selects.  An Award may also be granted to any consultant, agent, advisor or independent contractor for bona fide services rendered to the Company or any Related Company that (a) are not in connection with the offer and sale of the Company’s securities in a capital-raising transaction and (b) do not directly or indirectly promote or maintain a market for the Company’s securities.

SECTION 6.  AWARDS

6.1

Form, Grant and Settlement of Awards

The Committee shall have the authority, in its sole discretion, to determine the type or types of Awards to be granted under the Plan.  Such Awards may be granted either alone or in addition to or in tandem with any other type of Award.  Any Award settlement may be subject to such conditions, restrictions and contingencies as the Committee shall determine.

6.2

Evidence of Awards

Awards granted under the Plan shall be evidenced by a written, including an electronic, notice or agreement that shall contain such terms, conditions, limitations and restrictions as the Committee shall deem advisable and that are not inconsistent with the Plan.

6.3

Deferrals

The Committee may permit or require a Participant to defer receipt of the payment of any Award.  If any such deferral election is permitted or required, the Committee, in its sole discretion, shall establish rules and procedures for such payment deferrals, which may include the grant of additional Awards or provisions for the payment or crediting of interest or dividend equivalents, including converting such credits to deferred stock unit equivalents.

- 3 -

6.4

Dividends and Distributions

Participants may, if the Committee so determines, be credited with dividends paid with respect to shares of Common Stock underlying an Award in a manner determined by the Committee in its sole discretion.  The Committee may apply any restrictions to the dividends or dividend equivalents that the Committee deems appropriate.  The Committee, in its sole discretion, may determine the form of payment of dividends or dividend equivalents, including cash, shares of Common Stock, Restricted Stock or Stock Units.

SECTION 7.  OPTIONS

7.1

Grant of Options

The Committee may grant Options designated as Incentive Stock Options or Nonqualified Stock Options.

7.2

Option Exercise Price

The exercise price for shares purchased under an Option shall be as determined by the Committee, but shall not be less than 100% of the Fair Market Value on the Grant Date, except in the case of Substitute Awards.  

7.3

Term of Options

Subject to earlier termination in accordance with the terms of the Plan and the instrument evidencing the Option, the maximum term of an Option shall be ten years from the Grant Date.

7.4

Exercise of Options

The Committee shall establish and set forth in each instrument that evidences an Option the time at which, or the installments in which, the Option shall vest and become exercisable, any of which provisions may be waived or modified by the Committee at any time.  To the extent an Option has vested and become exercisable, the Option may be exercised in whole or from time to time in part by delivery to or as directed or approved by the Company of a properly executed stock option exercise agreement or notice, in a form and in accordance with procedures established by the Committee, setting forth the number of shares with respect to which the Option is being exercised, the restrictions imposed on the shares purchased under such exercise agreement, if any, and such representations and agreements as may be required by the Committee, accompanied by payment in full as described in Sections 7.5 and 13.  An Option may be exercised only for whole shares and may not be exercised for less than a reasonable number of shares at any one time, as determined by the Committee.

7.5

Payment of Exercise Price

The exercise price for shares purchased under an Option shall be paid in full to the Company by delivery of consideration equal to the product of the Option exercise price and the number of shares purchased.  Such consideration must be paid before the Company will issue the shares being purchased and must be in a form or a combination of forms acceptable to the Committee for that purchase, which forms may include:

(a)

cash, check or wire transfer;

(b)

having the Company withhold shares of Common Stock that would otherwise be issued to the Participant that on the day prior to the exercise date have an aggregate Fair Market Value equal to the aggregate exercise price of the shares being purchased under the Option;

(c)

tendering (either actually or, so long as the Common Stock is registered under Section 12(b) or 12(g) of the Exchange Act, by attestation) shares of Common Stock that on the day prior to the exercise date have an aggregate Fair Market Value equal to the aggregate exercise price of the shares being purchased under the Option owned by the Participant for at least six months (or any other period necessary to avoid adverse accounting consequences to the Company);

- 4 -

(d)

so long as the Common Stock is registered under Section 12(b) or 12(g) of the Exchange Act, and to the extent permitted by law, delivery of a properly executed exercise notice, together with irrevocable instructions to a brokerage firm designated or approved by the Company to deliver promptly to the Company the aggregate amount of  proceeds to pay the Option exercise price and any withholding tax obligations that may arise in connection with the exercise, all in accordance with the regulations of the Federal Reserve Board; or

(e)

such other consideration as the Committee may permit.

7.6

Effect of Termination of Service

The Committee shall establish and set forth in each instrument that evidences an Option whether the Option shall continue to be exercisable, and the terms and conditions of such exercise, after a Termination of Service, any of which provisions may be waived or modified by the Committee at any time.  If not so established in the instrument evidencing the Option, the Option shall be exercisable according to the following terms and conditions, which may be waived or modified by the Committee at any time:

(a)

Any portion of an Option that is not vested and exercisable on the date of a Participant’s Termination of Service shall expire on such date.

(b)

Any portion of an Option that is vested and exercisable on the date of a Participant’s Termination of Service shall expire on the earliest to occur of:

(i)

if the Participant’s Termination of Service occurs for reasons other than Cause, Retirement, Disability or death, the date that is three months after such Termination of Service;

(ii)

if the Participant’s Termination of Service occurs by reason of Retirement, Disability or death, the one-year anniversary of such Termination of Service; and

(iii)

the last day of the maximum term of the Option (the “Option Expiration Date”).

Notwithstanding the foregoing, if a Participant dies after his or her Termination of Service but while an Option is otherwise exercisable, the portion of the Option that is vested and exercisable on the date of such Termination of Service shall expire upon the earlier to occur of (y) the Option Expiration Date and (z) the one-year anniversary of the date of death, unless the Committee determines otherwise.

Also notwithstanding the foregoing, in case a Participant’s Termination of Service occurs for Cause, all Options granted to the Participant shall automatically expire upon first notification to the Participant of such termination, unless the Committee determines otherwise.  If a Participant’s employment or service relationship with the Company is suspended pending an investigation of whether the Participant shall be terminated for Cause, all the Participant’s rights under any Option shall likewise be suspended during the period of investigation.  If any facts that would constitute termination for Cause are discovered after a Participant’s Termination of Service, any Option then held by the Participant may be immediately terminated by the Committee, in its sole discretion.

(c)

A Participant’s change in status from an employee to a consultant, advisor or independent contractor, or a change in status from a consultant, advisor or independent contractor to an employee, shall not be considered a Termination of Service for purposes of this Section 7.6.

- 5 -

SECTION 8.  INCENTIVE STOCK OPTION LIMITATIONS

8.2

Eligible Employees

Individuals who are not employees of the Company or one of its parent or subsidiary corporations may not be granted Incentive Stock Options.

An Option designated as an Incentive Stock Option shall cease to qualify for favorable tax treatment as an Incentive Stock Option to the extent it is exercised (if permitted by the terms of the Option) (a) more than three months after the date of a Participant’s Termination of Service if termination was for reasons other than death or disability, (b) more than one year after the date of a Participant’s Termination of Service if termination was by reason of disability, or (c) after the Participant has been on leave of absence for more than 90 days, unless the Participant’s reemployment rights are guaranteed by statute or contract.

9.1

Grant of Stock Appreciation Rights

The Committee may grant Stock Appreciation Rights to Participants at any time on such terms and conditions as the Committee shall determine in its sole discretion.  An SAR may be granted in tandem with an Option or alone (“freestanding”).  The grant price of a tandem SAR shall be equal to the exercise price of the related Option.  The grant price of a freestanding SAR shall be established in accordance with procedures for Options set forth in Section 7.2.  An SAR may be exercised upon such terms and conditions and for the term as the Committee determines in its sole discretion; provided, however, that, subject to earlier termination in accordance with the terms of the Plan and the instrument evidencing the SAR, the term of a freestanding SAR shall be as established for that SAR by the Committee or, if not so established, shall be ten years, and in the case of a tandem SAR, (a) the term shall not exceed the term of the related Option and (b) the tandem SAR may be exercised for all or part of the shares subject to the related Option upon the surrender of the right to exercise the equivalent portion of the related Option, except that the tandem SAR may be exercised only with respect to the shares for which its related Option is then exercisable.

9.2

Payment of SAR Amount

Upon the exercise of an SAR, a Participant shall be entitled to receive payment in an amount determined by multiplying:  (a) the difference between the Fair Market Value of the Common Stock on the date of exercise over the grant price of the SAR by (b) the number of shares with respect to which the SAR is exercised.  At the discretion of the Committee as set forth in the instrument evidencing the Award, the payment upon exercise of an SAR may be in cash, in shares, in some combination thereof or in any other manner approved by the Committee in its sole discretion.

SECTION 11.  PERFORMANCE AWARDS

11.1

Performance Shares

The Committee may grant Awards of Performance Shares, designate the Participants to whom Performance Shares are to be awarded and determine the number of Performance Shares and the terms and conditions of each such Award.  Performance Shares shall consist of a unit valued by reference to a designated number of shares of Common Stock, the value of which may be paid to the Participant by delivery of shares of Common Stock or, if set forth in the instrument evidencing the Award, of such property as the Committee shall determine, including, without limitation, cash, shares of Common Stock, other property, or any combination thereof, upon the attainment of performance goals, as established by the Committee, and other terms and conditions specified by the Committee.  Notwithstanding the foregoing, the amount to be paid under an Award of Performance Shares may be adjusted on the basis of such further consideration as the Committee shall determine in its sole discretion.

11.2

Performance Units

The Committee may grant Awards of Performance Units, designate the Participants to whom Performance Units are to be awarded and determine the number of Performance Units and the terms and conditions of each such Award.  Performance Units shall consist of a unit valued by reference to a designated amount of property other than shares of Common Stock, which value may be paid to the Participant by delivery of such property as the Committee shall determine, including, without limitation, cash, shares of Common Stock, other property, or any combination thereof, upon the attainment of performance goals, as established by the Committee, and other terms and conditions specified by the Committee.  Notwithstanding the foregoing, the amount to be paid under an Award of Performance Units may be adjusted on the basis of such further consideration as the Committee shall determine in its sole discretion.

SECTION 12.  OTHER STOCK OR CASH-BASED AWARDS

Subject to the terms of the Plan and such other terms and conditions as the Committee deems appropriate, the Committee may grant other incentives payable in cash or in shares of Common Stock under the Plan.

SECTION 13.  WITHHOLDING

The Company may require the Participant to pay to the Company the amount of (a) any taxes that the Company is required by applicable federal, state, local or foreign law to withhold with respect to the grant, vesting or exercise of an Award (“tax withholding obligations”) and (b) any amounts due from the Participant to the Company or to any Related Company (“other obligations”).  The Company shall not be required to issue any shares of Common Stock or otherwise settle an Award under the Plan until such tax withholding obligations and other obligations are satisfied.

The Committee may permit or require a Participant to satisfy all or part of the Participant’s tax withholding obligations and other obligations by (a) paying cash to the Company, (b) having the Company withhold an amount from any cash amounts otherwise due or to become due from the Company to the Participant, (c) having the Company withhold a number of shares of Common Stock that would otherwise be issued to the Participant (or become vested, in the case of Restricted Stock) having a Fair Market Value equal to the tax withholding obligations and other obligations, or (d) surrendering a number of shares of Common Stock the Participant already owns having a value equal to the tax withholding obligations and other obligations.  The value of the shares so withheld may not exceed the employer’s minimum required tax withholding rate, and the value of the shares so tendered may not

- 8 -

exceed such rate to the extent the Participant has owned the tendered shares for less than six months, if such limitations are necessary to avoid adverse accounting consequences to the Company.

SECTION 14.  ASSIGNABILITY

No Award or interest in an Award may be sold, assigned, pledged (as collateral for a loan or as security for the performance of an obligation or for any other purpose) or transferred by a Participant or made subject to attachment or similar proceedings otherwise than by will or by the applicable laws of descent and distribution, except to the extent the Participant designates one or more beneficiaries on a Company-approved form who may exercise the Award or receive payment under the Award after the Participant’s death.  During a Participant’s lifetime, an Award may be exercised only by the Participant.  Notwithstanding the foregoing and to the extent permitted by Section 422 of the Code, the Committee, in its sole discretion, may permit a Participant to assign or transfer an Award to a Permitted Transferee subject to such terms and conditions as the Committee shall specify.

SECTION 15.  ADJUSTMENTS

15.1

Adjustment of Shares

In the event, at any time or from time to time, a stock dividend, stock split, spin-off, combination or exchange of shares, recapitalization, merger, consolidation, distribution to stockholders other than a normal cash dividend, or other change in the Company’s corporate or capital structure results in (a) the outstanding shares of Common Stock, or any securities exchanged therefor or received in their place, being exchanged for a different number or kind of securities of the Company or (b) new, different or additional securities of the Company or any other company being received by the holders of shares of Common Stock, then the Committee shall make proportional adjustments in (i) the maximum number and kind of securities available for issuance under the Plan; (ii) the maximum number and kind of securities issuable to an individual in a calendar year as set forth in Section 16.3 and as Incentive Stock Options as set forth in Section 4.2; and (iii) the number and kind of securities that are subject to any outstanding Award and the per share price of such securities, without any change in the aggregate price to be paid therefor.  The determination by the Committee, as to the terms of any of the foregoing adjustments shall be conclusive and binding.

Notwithstanding the foregoing, the issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, for cash or property, or for labor or services rendered, either upon direct sale or upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of the Company convertible into such shares or other securities, shall not affect, and no adjustment by reason thereof shall be made with respect to, outstanding Awards.  Also notwithstanding the foregoing, a dissolution or liquidation of the Company or a Company Transaction shall not be governed by this Section 15.1 but shall be governed by Sections 15.2 and 15.3, respectively.

15.2

Change In Control

The following provisions shall apply unless a Participant’s written agreement provides otherwise. If, while any Options, Stock Appreciation Rights, Restricted Stock Awards or Performance Awards are outstanding under the Plan, there shall occur (a) a merger or consolidation of the Company with or into another  corporation  in which the Company shall not be the surviving corporation, (b) a dissolution of the Company, or (c) a transfer of all or substantially all of the assets of the Company in one transaction or a series of related transactions to one or more other persons or entities, then, with respect to each Option, Stock Appreciation Right and Restricted Stock Award outstanding immediately prior to the consummation of such transaction, if provision is not otherwise made in writing in connection with such transaction for the substitution of securities of another corporation, and without the necessity of any action by the Board of Directors, each such Option, Stock Appreciation Right, Restricted Stock Award or Performance Award shall terminate, but (A) the holder of any outstanding Option shall be entitled, immediately prior to the effective date of such transaction, to purchase the number of shares that are then vested and exercisable; (B) the holder of any Stock Appreciation Right shall be entitled, immediately prior to the effective date of such transaction, to exercise such Right to the extent the Option is exercisable at such time in accordance with its terms; and (C) the recipient of any Performance Award shall be entitled, immediately prior to the effective date of such transaction, to receive the then vested shares or values under such Award.  The unexercised portion of any

- 9 -

Option or Stock Appreciation Right, and all non-vested Restricted Stock, Stock Unit and Performance Awards shall be deemed canceled, forfeited, and terminated as of the effective date of such transaction.

15.3

Change in Control Cash Out

Notwithstanding the foregoing, the Committee, in its sole discretion, may instead provide that a Participant’s outstanding Awards shall terminate upon or immediately prior to such a transaction and that the Participant shall receive, in exchange therefor, a cash payment equal to the amount (if any) by which (x) the value of the per share consideration received by holders of Common Stock in such transaction, or, in the event the transaction does not result in direct receipt of consideration by holders of Common Stock, the value of the deemed per share consideration received, in each case as determined by the Committee in its sole discretion, multiplied by the number of shares of Common Stock subject to such outstanding Awards (to the extent then vested and exercisable or whether or not then vested and exercisable, as determined by the Committee in its sole discretion) exceeds (y) if applicable, the respective aggregate exercise price or grant price for such Award.

15.4

Further Adjustment of Awards

Subject to Section 15.2 and 15.3, the Committee shall have the discretion, exercisable at any time before a sale, merger, consolidation, reorganization, liquidation, dissolution or change in control of the Company, as defined by the Committee, to take such further action as it determines to be necessary or advisable with respect to Awards.  Such authorized action may include (but shall not be limited to) establishing, amending or waiving the type, terms, conditions or duration of, or restrictions on, Awards so as to provide for earlier, later, extended or additional time for exercise, lifting restrictions and other modifications, and the Committee may take such actions with respect to all Participants, to certain categories of Participants or only to individual Participants.  The Committee may take such action before or after granting Awards to which the action relates and before or after any public announcement with respect to such sale, merger, consolidation, reorganization, liquidation, dissolution or change in control that is the reason for such action.

15.5

No Limitations

The grant of Awards shall in no way affect the Company’s right 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.

15.6

Fractional Shares

In the event of any adjustment in the number of shares covered by any Award, each such Award shall cover only the number of full shares resulting from such adjustment.

15.7

Section 409A of the Code

Notwithstanding anything in this Plan to the contrary, (a) any adjustments made pursuant to this Section 15 to Awards that are considered “deferred compensation” within the meaning of Section 409A of the Code are intended to be made in compliance with the requirements of Section 409A of the Code; (b) any adjustments made pursuant to Section 15 to Awards that are not considered “deferred compensation” subject to Section 409A of the Code are intended to be made in such a manner as to ensure that after such adjustment the Awards either (i) continue not to be subject to Section 409A of the Code or (ii) comply with the requirements of Section 409A of the Code; and (c) in any event, the Committee shall not have the authority to make any adjustments pursuant to Section 15 to the extent the existence of such authority would cause an Award that is not intended to be subject to Section 409A of the Code at the time of grant to be subject thereto; provided however that notwithstanding anything to the contrary in the Plan in no event shall the Company be liable to any Participant for or with respect to any taxes, penalties or interest which may be imposed upon a Participant pursuant to Section 409A of the Code.

- 10 -

SECTION 16.  CODE SECTION 162(m) PROVISIONS

Notwithstanding any other provision of the Plan, if the Committee determines, at the time Awards are granted to a Participant who is, or is likely to be as of the end of the tax year in which the Company would claim a tax deduction in connection with such Award, a Covered Employee, then the Committee may provide that this Section 16 is applicable to such Award.

If an Award is subject to this Section 16, then the lapsing of restrictions thereon and the distribution of cash, shares of Common Stock or other property pursuant thereto, as applicable, shall be subject to the achievement of one or more objective performance goals established by the Committee, which shall be based on the attainment of specified levels of one of or any combination of the following “performance criteria” for the Company as a whole or any business unit of the Company, as reported or calculated by the Company:  cash flows (including, but not limited to, operating cash flow, free cash flow or cash flow return on capital); working capital; earnings per share; book value per share; operating income (including or excluding depreciation, amortization, extraordinary items, restructuring charges or other expenses); revenues; operating margins; return on assets; return on equity; debt; debt plus equity; market or economic value added; stock price appreciation; total stockholder return; cost control; strategic initiatives; market share; net income; return on invested capital; improvements in capital structure; or customer satisfaction, employee satisfaction, services performance, subscriber, cash management or asset management metrics (together, the “Performance Criteria”).  Such performance goals also may be based on the achievement of specified levels of Company performance (or performance of an applicable affiliate or business unit of the Company) under one or more of the Performance Criteria described above relative to the performance of other corporations.  Such performance goals shall be set by the Committee within the time period prescribed by, and shall otherwise comply with the requirements of, Section 162(m) of the Code, or any successor provision thereto, and the regulations thereunder.

16.2

Adjustment of Awards

Notwithstanding any provision of the Plan other than Section 15, with respect to any Award that is subject to this Section 16, the Committee may adjust downwards, but not upwards, the amount payable pursuant to such Award, and the Committee may not waive the achievement of the applicable performance goals except in the case of the death or disability of the Covered Employee.

16.3

Limitations

Subject to adjustment from time to time as provided in Section 15.1, no Covered Employee may be granted Awards other than Performance Units subject to this Section 16 in any calendar year period with respect to more than 5,000,000 shares of Common Stock for such Award, and the maximum dollar value payable with respect to Performance Units subject to this Section 16 granted to any Covered Employee in any one calendar year is $500,000.

The Committee shall have the power to impose such other restrictions on Awards subject to this Section 16 as it may deem necessary or appropriate to ensure that such Awards satisfy all requirements for “performance-based compensation” within the meaning of Section 162(m)(4)(C) of the Code, or any successor provision thereto.

SECTION 17.  AMENDMENT AND TERMINATION

17.1

Amendment, Suspension or Termination

The Board or the Compensation Committee may amend, suspend or terminate the Plan or any portion of the Plan at any time and in such respects as it shall deem advisable; provided, however, that, to the extent required by applicable law, regulation or stock exchange rule, stockholder approval shall be required for any amendment to the Plan; and provided, further, that any amendment that requires shareholder approval may be made only by the Board.  Subject to Section 17.3, the Committee may amend the terms of any outstanding Award, prospectively or retroactively.

- 11 -

17.2

Term of the Plan

Unless sooner terminated as provided herein, the Plan shall terminate ten years from the Effective Date.  After the Plan is terminated, no future Awards may be granted, but Awards previously granted shall remain outstanding in accordance with their applicable terms and conditions and the Plan’s terms and conditions.  Notwithstanding the foregoing, no Incentive Stock Options may be granted more than ten years after the later of (a) the Effective Date and (b) the approval by the stockholders.

17.3

Consent of Participant

The amendment, suspension or termination of the Plan or a portion thereof or the amendment of an outstanding Award shall not, without the Participant’s consent, materially adversely affect any rights under any Award theretofore granted to the Participant under the Plan.  Any change or adjustment to an outstanding Incentive Stock Option shall not, without the consent of the Participant, be made in a manner so as to constitute a “modification” that would cause such Incentive Stock Option to fail to continue to qualify as an Incentive Stock Option.  Notwithstanding the foregoing, any adjustments made pursuant to Section 15 shall not be subject to these restrictions.

SECTION 18.  GENERAL

18.1

No Individual Rights

No individual or Participant shall have any claim to be granted any Award under the Plan, and the Company has no obligation for uniformity of treatment of Participants under the Plan.

Furthermore, nothing in the Plan or any Award granted under the Plan shall be deemed to constitute an employment contract or confer or be deemed to confer on any Participant any right to continue in the employ of, or to continue any other relationship with, the Company or any Related Company or limit in any way the right of the Company or any Related Company to terminate a Participant’s employment or other relationship at any time, with or without cause.

18.2

Issuance of Shares

Notwithstanding any other provision of the Plan, the Company shall have no obligation to issue or deliver any shares of Common Stock under the Plan or make any other distribution of benefits under the Plan unless, in the opinion of the Company’s counsel, such issuance, delivery or distribution would comply with all applicable laws (including, without limitation, the requirements of the Securities Act or the laws of any state or foreign jurisdiction) and the applicable requirements of any securities exchange or similar entity.

The Company shall be under no obligation to any Participant to register for offering or resale or to qualify for exemption under the Securities Act, or to register or qualify under the laws of any state or foreign jurisdiction, any shares of Common Stock, security or interest in a security paid or issued under, or created by, the Plan, or to continue in effect any such registrations or qualifications if made.

As a condition to the exercise of an Option or any other receipt of Common Stock pursuant to an Award under the Plan, the Company may require (a) the Participant to represent and warrant at the time of any such exercise or receipt that such shares are being purchased or received only for the Participant’s own account and without any present intention to sell or distribute such shares and (b) such other action or agreement by the Participant as may from time to time be necessary to comply with the federal, state and foreign securities laws.  At the option of the Company, a stop-transfer order against any such shares may be placed on the official stock books and records of the Company, and a legend indicating that such shares may not be pledged, sold or otherwise transferred, unless an opinion of counsel is provided (concurred in by counsel for the Company) stating that such transfer is not in violation of any applicable law or regulation, may be stamped on stock certificates to ensure exemption from registration.  The Committee may also require the Participant to execute and deliver to the Company a purchase agreement or such other agreement as may be in use by the Company at such time that describes certain terms and conditions applicable to the shares.

- 12 -

To the extent the Plan or any instrument evidencing an Award provides for issuance of stock certificates to reflect the issuance of shares of Common Stock, the issuance may be affected on a noncertificated basis, to the extent not prohibited by applicable law or the applicable rules of any stock exchange.

18.3

Indemnification

Each person who is or shall have been a member of the Board, or a committee appointed by the Board, or an officer of the Company to whom authority was delegated in accordance with Section 3, shall be indemnified and held harmless by the Company against and from any loss, cost, liability or expense that may be imposed upon or reasonably incurred by such person in connection with or resulting from any claim, action, suit or proceeding to which such person may be a party or in which such person may be involved by reason of any action taken or failure to act under the Plan and against and from any and all amounts paid by such person in settlement thereof, with the Company’s approval, or paid by such person in satisfaction of any judgment in any such claim, action, suit or proceeding against such person; provided, however, that such person shall give the Company an opportunity, at its own expense, to handle and defend the same before such person undertakes to handle and defend it on such person’s own behalf, unless such loss, cost, liability or expense is a result of such person’s own willful misconduct or except as expressly provided by statute.

The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such person may be entitled under the Company’s certificate of incorporation or bylaws, as a matter of law, or otherwise, or of any power that the Company may have to indemnify or hold harmless.

18.4

No Rights as a Stockholder

Unless otherwise provided by the Committee or in the instrument evidencing the Award or in a written employment, services or other agreement, no Award, other than a Stock Award, shall entitle the Participant to any cash dividend, voting or other right of a stockholder unless and until the date of issuance under the Plan of the shares that are the subject of such Award.

18.5

Compliance With Laws and Regulations

In interpreting and applying the provisions of the Plan, any Option granted as an Incentive Stock Option pursuant to the Plan shall, to the extent permitted by law, be construed as an “incentive stock option” within the meaning of Section 422 of the Code.

18.6

Participants in Other Countries or Jurisdictions

Without amending the Plan, the Committee may grant Awards to Eligible Persons who are foreign nationals on such terms and conditions different from those specified in this Plan as may, in the judgment of the Committee, be necessary or desirable to foster and promote achievement of the purposes of the Plan and shall have the authority to adopt such modifications, procedures, subplans and the like as may be necessary or desirable to comply with provisions of the laws or regulations of other countries or jurisdictions in which the Company or any Related Company may operate or have employees to ensure the viability of the benefits from Awards granted to Participants employed in such countries or jurisdictions, meet the requirements that permit the Plan to operate in a qualified or tax-efficient manner, comply with applicable foreign laws or regulations and meet the objectives of the Plan.

18.7

No Trust or Fund

The Plan is intended to constitute an “unfunded” plan.  Nothing contained herein shall require the Company to segregate any monies or other property, or shares of Common Stock, or to create any trusts, or to make any special deposits for any immediate or deferred amounts payable to any Participant, and no Participant shall have any rights that are greater than those of a general unsecured creditor of the Company.

- 13 -

18.8

Successors

All obligations of the Company under the Plan with respect to Awards shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all the business and/or assets of the Company.

18.9

Severability

If any provision of the Plan or any Award is determined to be invalid, illegal or unenforceable in any jurisdiction, or as to any person, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to applicable laws, or, if it cannot be so construed or deemed amended without, in the Committee’s determination, materially altering the intent of the Plan or the Award, such provision shall be stricken as to such jurisdiction, person or Award, and the remainder of the Plan and any such Award shall remain in full force and effect.

18.10

Choice of Law

The Plan, all Awards granted thereunder and all determinations made and actions taken pursuant hereto, to the extent not otherwise governed by the laws of the United States, shall be governed by the laws of the State of Idaho without giving effect to principles of conflicts of law.

18.11

Legal Requirements

The granting of Awards and the issuance of shares of Common Stock under the Plan is subject to all applicable laws, rules and regulations and to such approvals by any governmental agencies or national securities exchanges as may be required.

SECTION 19.  EFFECTIVE DATE

The effective date (the “Effective Date”) is the date on which the Plan as amended and restated as authorized as by the Board on February 13, 2015 and approved by the Board on April 29, 2015 is approved by the stockholders of the Company.  If the stockholders of the Company do not approve the Plan within 12 months after the Board’s adoption of the Plan, any Incentive Stock Options granted under the Plan will be treated as Nonqualified Stock Options.
