5.02 — Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements

of Certain Officers.

On

April 30, 2026 (the “Effective Date”), the Compensation Committee of the Board of Directors (the “Compensation Committee”)

of Milestone Scientific Inc. (the “Company”) approved a one-time stock option exchange program (the “Exchange Program”)

for outstanding stock options granted under the Company’s Amended and Restated 2020 Equity Incentive Plan (the “2020 Plan”)

and the applicable award agreements thereunder, held by Eric Hines, the President and Chief Executive Officer, and Jason Papes, the Senior

Vice President, Global Head of Sales and Marketing, of the Company (“Eligible Options”), all of which have exercise prices

that exceed the current fair market value of the Company’s common stock (the “Common Stock”). The Exchange Program

was undertaken in accordance with, and as expressly permitted by, the 2020 Plan and the applicable award agreements thereunder, and provides

that such eligible participants may voluntarily elect to surrender some or all of their Eligible Options in exchange for newly granted

stock options to purchase shares of the Company’s Common Stock, at an exercise price reduced to $0.31 per share (the “Reduced

Exercise Price”), which exercise price equals the closing price of the Company’s Common Stock on the Effective Date

(the “Repricing”). All of the Eligible Options (i) were granted under the 2020 Plan, (ii) as of the Effective Date, were

held by continuing employees, (iii) had not previously been repriced and (iv) had an exercise price per share greater than the Reduced

Exercise Price (the “Repriced Options”). The Repriced Options have the same vesting commencement date and expiration date

as the respective Eligible Options surrendered. In addition, for each Repriced Option, the vesting schedule was modified such that the

number of shares vesting on the applicable vesting commencement date was increased from 200,000 to 500,000 shares, constituting twenty-five

percent (25%) of the total number of shares subject to the Repriced Option, and providing for the vesting of the remainder of the shares

subject to the Repriced Options in two equal tranches of 750,000 shares on the first and second anniversaries of the applicable vesting

commencement date rather than over three years from the vesting commencement date, subject to the continued employment of the grantee

on the applicable vesting date and compliance with certain restrictive covenants. No other changes were made to the Repriced Options

as a result of the Repricing.

The

number of shares of Common Stock issuable upon the exercise of each of the Repriced Options (2.0 million shares), and the total number

of shares underlying all Repriced Options (4.0 million shares), remains the same number of shares as underlying the respective Eligible

Options surrendered, in accordance with the 2020 Plan. The Eligible Options previously had exercise prices ranging from $0.46 to $0.50

per share, and were granted in August 2025.

The

Compensation Committee approved the Repricing after multiple discussions, careful consideration of various alternatives and a review

of other applicable factors, including the diminished retention and incentive value of the Eligible Options since the onboarding of the

grantees in August 2025 and that the Exchange Program would better align employee incentives with the interests of stockholders.

The

Compensation Committee designed the Repricing to provide added incentive to retain and motivate the holders of the Repriced Options to

continue to work in the best interests of the Company and its stockholders without incurring stock dilution resulting from additional

equity grants or significant additional cash expenditures resulting from additional cash compensation.

Also

on April 30, 2026, the Compensation Committee approved the grant of performance-based restricted stock units (“PRSUs”) to

certain officers of the Company. The PRSUs were awarded in accordance with, and as permitted by, the 2020 Plan. As all of the PRSUs are

to have the same performance milestones and other terms and conditions (other than the actual grant amounts), the Compensation Committee

established a sub-plan of the 2020 Plan (the “Sub-Plan”) as the framework together with the 2020 Plan for the award of PRSUs

(each, an “Award” and collectively, “Awards”), with a fixed pool of PRSUs allocated to each of the five (5) performance

milestones set forth below. The award of PRSUs under the Sub-Plan is subject to stockholder approval of an amendment of the 2020 Plan

to increase the number of shares covered by the 2020 Plan to account for Awards under the Sub-Plan.

The

Compensation Committee may select such senior officers and directors of the Company as the Compensation Committee may designate to participate

in the Sub-Plan and receive Awards from time to time. The performance period for achievement of each of the performance milestones is

the four (4) year period beginning January 1, 2026 and ending December 31, 2029 (the “Performance Period”).

Subject

to stockholder approval, the total aggregate number of shares of Common Stock that may be issued under the Sub-Plan upon full satisfaction

of all Performance Milestones is 17,234,635 shares (the “Aggregate Pool”).

Each

Award will be comprised of the following Performance Milestones and each Performance Milestone will be allocated up to the specified

percentage of the Aggregate Pool:

Performance Milestone

Sub-Pool

(percentage of Aggregate Pool)

Last twelve month net sales from organic growth, for existing business lines greater than $11.0 million

20%

Last twelve month net sales from organic growth, for existing business lines greater than $13.0 million

20%

Last twelve month net sales from organic growth, for existing business lines greater than $15.0 million

30%

Company’s Market Capitalization of at least $50 million

15%

“Qualified Acquisition” consummated (having more than $10 million of revenue)

15%

No

one participant shall, in the aggregate under the Sub-Plan, be granted or allocated more than thirty percent (30%) of the PRSUs allocated

to any Sub-Pool or under the Sub-Plan.

Subject

to stockholder approval, the total aggregate number of shares of Common Stock that may be issued under the Sub-Plan in settlement of

Awards granted and upon full satisfaction of all Performance Milestones with respect to such Awards is 11,202,513, which Awards have

been granted to the following officers of the Company:

Jason Papes

All

Awards will be in the form of stock-settled PRSUs, and subject to the terms and conditions of an award agreement (consistent with the

provisions of the Sub-Plan and the 2020 Plan). Each PRSU will be equivalent to one share of Common Stock and shall entitle the participant

to receive from the Company at the settlement thereof applicable to such PRSU one share of Common Stock. The dollar value of shares issuable

upon settlement of Awards is not calculable at this time.

Awards

with respect to a Performance Milestone shall vest upon achievement of each Performance Milestone, subject to certification by the Compensation

Committee that such Performance Milestone has been met, satisfaction of continued employment by the participant and the other requirements

set forth in the Sub-Plan, except that any part of an Award the Performance Milestone of which (other than with respect to a Qualified

Acquisition) is achieved within twelve (12) months after such grant to a participant shall be treated as if such Performance Milestone

was not so achieved for such participant.

If

a grantee’s service with the Company terminates for any reason prior to the achievement of the applicable Performance Milestone,

the right to any portion of the Award that has not vested prior to the grantee’s termination of employment will be forfeited in

full and cancelled without consideration as of the termination of employment; provided, that if a Performance Milestone is achieved while

the grantee is a service provider and thereafter the grantee experiences a termination of service for any reason (except if in connection

with the occurrence of a termination of employment for “cause”), such grantee shall not be deemed to have experienced a termination

of service solely for purposes of determining entitlement to such Award relating to Performance Milestones achieved prior to the termination

of service the achievement of which is thereafter certified by the Compensation Committee.

In

the event of a participant’s termination of service for cause, or a breach in any material respect of any provision of an agreement

between such participant and the Company or a violation of certain non-competition, non-disclosure or use covenants in the Sub-Plan,

all Awards granted to such participant (including any vested portion thereof) shall immediately terminate and be forfeited in its entirety,

and if the participant vests in any of his or her Award, within one year thereafter, the participant may, in the discretion of the Compensation

Committee, be required to re-deliver to the Company the shares delivered to the participant (or if such shares have been sold, their

aggregate selling price).

Upon

a Change in Control (as defined in the Sub-Plan), all Awards theretofore granted shall be deemed cancelled and terminated, except that

Awards corresponding to Performance Milestones achieved and certified prior to the Change in Control shall vest and settle in accordance

with the Sub-Plan, and PRSUs allocated to the Market Capitalization Performance Milestone shall be based on the imputed value of the

Company in such Change in Control transaction. No vesting or right to any shares or compensation will arise from any achievement of any

Performance Milestone occurring after a Change in Control. Upon the forfeiture of any Award, the forfeited PRSUs cannot be re-allocated

to any participant in the Sub-Plan.

The

Compensation Committee designed the Sub-Plan and awards thereunder to provide added incentive to retain and motivate senior executives

of the Company to continue to work in the best interests of the Company and its stockholders without incurring significant additional

cash expenditures resulting from additional cash compensation, and to promote the long-term growth and profitability of the Company and

its subsidiaries by providing long-term incentives to maximize stockholder value and otherwise contribute to the success of the Company.

The

foregoing description of the Sub-Plan and related award agreement is qualified in its entirety by reference to the Sub-Plan and form

of award agreement, copies of which are filed herewith.

Termination

by the Company without Cause or by you for Good Reason. If you experience a Termination of Service by the Company without Cause

or by you for Good Reason, then the vesting of the Option as of the date of termination shall accelerate to the extent necessary

written offer with respect to a Change in Control is executed while the Grantee is employed by the Company or any Subsidiary thereof

but Grantee’s employment is terminated by the Company and its Subsidiaries for reasons other than Cause prior to the consummation

of the Change in Control, then all unvested Options shall vest on the consummation of such Change in Control as if the Grantee had

to acquire common equity securities to employees, officers, directors, consultants or other service providers of the Company or any

Option may be exercised with respect to the portion hereof vested on Grantee’s Termination

and the Plan. This Option is intended to be an Incentive Stock Option (“ISO”) as defined in Section 422 of

the Code only to the extent so designated in the Notice of Stock Option Grant, and to the extent it is not so designated or to the extent

this Option does not qualify as an Incentive Stock Option, it is intended to be a Nonstatutory Stock Option.

Notwithstanding

the above, if designated as an Incentive Stock Option, in the event that the Shares subject to this Option (and all other Incentive Stock

Options granted to you by the Company or any Parent or Subsidiary, including under other plans) that first become exercisable in any

calendar year have an aggregate fair market value (determined for each Share as of the date of grant of the Option covering such Share)

in excess of USD$100,000, the Shares in excess of USD$100,000 shall be treated as subject to a nonstatutory stock option, in accordance

with Section 8 of the Plan.

2.2

Vesting.

(a)

Continued Employment. Except as otherwise provided herein, Grantee shall be employed by the Company or any of its Subsidiaries

for any period of time during which you are an employee of the Company or any of its Subsidiaries, as determined by the Company in accordance

with its applicable practices, policies and records; provided, that, during such period you are (i) in active employment status with

the Company or any of its Subsidiaries, (ii) on a Company-approved leave of absence for up to six months (or greater than six months

if you have a right to reemployment under a statute or contract), or (iii) on leave due to Disability for up to the applicable period

your job is protected by statute or as approved by the Company. For the avoidance of doubt, you shall not be considered to be employed

(x) for any period during which you are not considered to be an employee pursuant to the Company’s practices, policies and records,

(y) during any notice period or salary continuation period required by local law or contract (such as a “garden leave” or

similar period) or any severance period (if you are covered by a severance agreement or arrangement) or (z) for any period of leave in

excess of the periods set forth in clauses (ii) and (iii) above, as applicable. For purposes of Incentive Stock Options, no such leave

may exceed 90 days, unless reemployment upon expiration of such leave is guaranteed by statute or contract. If reemployment upon expiration

of a leave of absence approved by the Company is not so guaranteed, then three months following the 91st day of such leave, any Incentive

Stock Option held by Grantee shall cease to be treated as an Incentive Stock Option and shall be treated for tax purposes as a Nonstatutory

Stock Option. Service as a Director, whether or not you receive payment of a director’s fee by the Company, shall be sufficient

to constitute “employment” by the Company for purposes of this Agreement.

-4-

(b)

Vesting. Subject to the provisions contained herein, this Option is exercisable during its term in accordance with the Vesting

Schedule set forth in Section 1 and the applicable provisions of this Option Agreement and the Plan. In no event will this Option become

exercisable for additional Shares after a Termination of Service for any reason. Notwithstanding the foregoing, this Option becomes exercisable

in full if the Company is subject to a Change in Control before the Grantee’s Termination of Service, and within 12 months after

the Change in Control the Grantee is subject to a Termination of Service resulting from: (i) the Grantee’s involuntary discharge

by the Company (or the Affiliate employing him or her) for reasons other than Cause (defined below), death or Disability; or (ii) the

Grantee’s resignation for Good Reason (defined below). This Option may also become exercisable in accordance with Section 2.2(d)

below.

(c)

Conditions on Vesting Upon or Following Termination of Employment. Your eligibility to vest in or exercise this Option (or any

portion thereof) upon or following the date of your termination of Employment shall be subject to (i) your compliance with the obligations

in Section 2.11 and/or any Company Agreement, and (ii) if required by the Company at the time of your termination of employment, your

execution of a general release of claims in favor of the Company and its Subsidiaries and affiliates in the form required by the Company

that becomes effective within sixty (60) days following the date of termination (or such earlier date as the Company may require).

(d)

Change in Control. In connection with a Change in Control, the Committee will notify the Grantee in writing or electronically

that the Option will be fully vested and exercisable for a period determined by the Committee in its sole discretion and, to the extent

this Option is not exercised prior to the expiration of such period (which may be the closing of such Change in Control), if the Committee

determines, reasonable prior written notice of which acceleration and termination shall be given to the Grantee, such unexercised Option

shall terminate upon or immediately prior to the effectiveness of such Change in Control.

2.3

Number of Shares and Exercise Price. The number of shares of Common Stock subject to this Option and the Exercise Price

per share in the Notice of Stock Option Grant will be adjusted as provided in the Plan.

-5-

2.4

Exercise of Option. This Option may be exercised only within the period set out in the Notice of Stock Option Grant, and

may be exercised during such period only in accordance with this Option Agreement and the Plan, and the Vesting Schedule and applicable

Exercise Period set out in the Notice of Stock Option Grant and with the provisions of this Section 2.4.

(a)

Method of Exercise. You may exercise the vested portion of this Option (and the unvested portion of Grantee’s Option if

and to the extent Grantee’s Notice of Stock Option Grant so permits) during its term by (i) delivering a Notice of Exercise (in

a form designated by the Company) or completing such other documents and/or procedures designated by the Company for exercise, (ii) paying

the Exercise Price and any applicable withholding taxes to the Company’s Secretary, stock plan administrator, or such other person

as the Company may designate, and delivering such additional documents as the Company may then require, and (iii) if the Company’s

Common Stock shall not be registered for trading on a U.S. national securities exchange or U.S. over-the-counter market, executing and

delivering any stockholders’ agreement, investors’ rights, co-sale or other similar agreement to which the holders of a majority

of the shares of Common Stock then issued and outstanding are parties (each, a “Stockholders’ Agreement”).

The Grantee is responsible for filing any reports of remittance or other foreign exchange filings required in order to pay the Exercise

Price. In no event may this Option be exercised after the Expiration Date set forth in the Notice of Stock Option Grant. If requested

by the Company, this Option grant is conditioned on Grantee opening and maintaining a brokerage account that is permitted for use with

respect to awards granted under the Plan, by the deadline established by the Company and/or set forth on the website of the Plan recordkeeper.

If you do not accept this Option grant by the applicable deadline, your grant will be cancelled.

(b)

Compliance. In no event may the Option be exercised unless the shares of Common Stock issuable upon exercise are then registered

under the Securities Act or, if not registered, the Company has determined that the exercise and the issuance of the Shares would be

exempt from the registration requirements of the Securities Act. The Company is not obligated, and will have no liability for failure,

to issue or deliver of any Shares upon exercise of this Option, and this Option may not be exercised, if the issuance of such Shares

upon such exercise or the method of payment of consideration for such Shares would constitute a violation of any applicable requirements

of federal, state and foreign laws with respect to such securities and other law and regulations or the requirements of any stock exchange

or market system upon which the Shares may then be listed, with such compliance determined by the Company in consultation with its legal

counsel. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to you on the date on which this

Option is exercised with respect to such Shares, subject to applicable laws. The inability of the Company to obtain the authority from

any regulatory body having jurisdiction, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance of

any Shares shall relieve the Company of any liability in respect of the failure to issue such Shares as to which such requisite authority

shall not have been obtained. As a condition to the issuance of the Shares, the Company may require you to satisfy any qualifications

that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or

warranty with respect thereto as may be requested by the Company. Furthermore, you understand that the applicable laws of the country

in which you are residing or working at the time of grant, vesting, and/or exercise of this Option (including any rules or regulations

governing securities, foreign exchange, tax, labor or other matters) may restrict or prevent exercise of this Option.

(c)

Compensation Recoupment Policy. In the event that any of the Options are at any time affected by an Accounting Restatement and

the Company has a compensation recoupment policy, whether on a stand-alone basis or combined with other policies, you hereby acknowledge

and agree that you and the Option, including any Shares that may be delivered to you pursuant to this Option, will be subject to such

compensation recoupment policy. The terms and conditions of any such compensation recoupment policy will be deemed incorporated by reference

into this Agreement. For purposes hereof, “Accounting Restatement” means the accounting restatement of any of the

Company’s financial statements filed with the Securities and Exchange Commission under the Exchange Act or the Securities Act of

1933, as amended, due to the Company’s material noncompliance with any financial reporting requirement under the securities laws,

including any required accounting restatement to correct an error in previously issued financial statements that is material to the previously

issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left

uncorrected in the current period.

(d)

Notice of Disqualifying Disposition. If Grantee’s Option is an Incentive Stock Option, by exercising Grantee’s Option

you agree that you will notify the Company in writing within fifteen (15) days after the date of any disposition of any of the shares

of the Common Stock issued upon exercise of Grantee’s Option that occurs within two (2) years after the Date of Grant or within

one (1) year after such shares of Common Stock are transferred upon exercise of Grantee’s Option.

-6-

(e)

Special Termination Period. If exercise of the Option on the last day of the termination period set forth in Section 1 is prevented

by operation of subparagraph (b) of this Section 2.4, then this Option shall remain exercisable until 14 days after the first date that

subparagraph (b) no longer operates to prevent exercise of the Option.

2.5

Method of Payment. Payment of the aggregate Exercise Price shall be by any of the following methods; provided, however,

the payment shall be in strict compliance with all procedures established by the Committee:

(a)

cash;

(b)

check or wire transfer;

(c)

subject to any conditions or limitations established by the Committee, other Shares Delivered to the Company that have a Fair Market

Value on the date of surrender or attestation equal to the aggregate Exercise Price; provided, that such already-owned shares of Common

Stock are owned free and clear of any liens, claims, encumbrances or security interests, and that are valued at Fair Market Value on

the date of exercise. “Delivery” for these purposes, in the sole discretion of the Company at the time you

exercise this Option, will include delivery to the Company of Grantee’s attestation of ownership of such shares of Common Stock

in a form approved by the Company. Grantee may not exercise this Option by delivery to the Company of Common Stock if doing so would

violate the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock.

(d)

consideration received by the Company under a broker-assisted sale and remittance program acceptable to the Committee pursuant to a program

developed under Regulation T as promulgated by the Federal Reserve Board that (Officers and Directors shall not be permitted to use this

procedure if this procedure would violate Section 402 of the Sarbanes-Oxley Act of 2002, as amended), including the receipt of irrevocable

instructions to pay the aggregate exercise price to the Company from the sales proceeds (this manner of payment is also known as a “broker-assisted

exercise”, “same day sale”, or “sell to cover”);

(e)

subject to any conditions or limitations established by the Committee, retention by the Company of so many of the Shares that would otherwise

have been delivered upon exercise of the Option as have a Fair Market Value on the exercise date equal to the aggregate exercise price

of all Shares as to which the Option is being exercised, provided that the Option is surrendered and cancelled as to such Shares; or

(f)

any combination of the foregoing methods of payment;

provided, that:

(i) fractional shares of Common Stock shall not be accepted as payment of the Exercise Price; (ii) shares of Common Stock that you acquired

within the six (6) month period immediately preceding the date of exercise may not be used to pay the Exercise Price; (iii) shares of

Common Stock that were issued to you by the Company upon your exercise of an incentive stock option within the one (1) year period immediately

preceding the exercise of the Option may not be used to pay the Exercise Price; and (iv) any shares of Common Stock used to pay the Exercise

Price (or any portion thereof) must be owned by you free and clear of any liens, encumbrances or security interests. Notwithstanding

the foregoing, if you are a director or Section 16 officer of the Company under the Securities Act, payment of the Exercise Price by

means of methods (c) (d) and (f) hereof is subject to approval by the Committee.

-7-

Grantee

understands and agrees that, if required by the Company or applicable laws, any cross-border cash remittance made to exercise this Option

or transfer proceeds received upon the sale of Shares must be made through a locally authorized financial institution or registered foreign

exchange agency and may require you to provide to such entity certain information regarding the transaction. Moreover, Grantee understands

and agrees that the future value of the underlying Shares is unknown and cannot be predicted with certainty and may decrease in value,

even below the Exercise Price. Grantee understands that neither the Company nor any Subsidiary or Affiliate is responsible for any foreign

exchange fluctuation between local currency and the United States Dollar or the selection by the Company or any Subsidiary or Affiliate

in its sole discretion of an applicable foreign currency exchange rate that may affect the value of this Option (or the calculation of

income or Tax-Related Items thereunder).

2.6

Non-Transferability of Option. This Option may not be transferred in any manner other than by will or by the laws of descent

and distribution, or in accordance with any beneficiary designation procedures that may be established by the Company, nor shall any

such rights be subject to execution, attachment or similar process, other than in accordance with the terms of the Plan. Upon any attempt

to sell, transfer, assign, pledge, hypothecate or otherwise dispose of the Option or of such rights contrary to the provisions of the

Plan or this Agreement, or upon the levy of any attachment or similar process upon the Option or such rights, the Option and such rights

shall, at the election of the Company, be forfeited for no consideration. This Option may be exercised during the lifetime of the Grantee

only by the Grantee. The terms of this Option Agreement and the Plan shall be binding upon the executors, administrators, heirs, successors,

and assigns of the Grantee. Notwithstanding the foregoing, if this Option is designated as a Nonstatutory Stock Option, the Committee

may, in its sole discretion, allow the Grantee to transfer this Option as a gift to one or more family members. For purposes of this

Option Agreement, “family member” means a child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse,

sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law (including adoptive

relationships), any individual sharing the Grantee’s household (other than a tenant or employee), a trust in which one or more

of these individuals have 100% of the beneficial interest, a foundation in which the Grantee or one or more of these persons control

the management of assets, and any entity in which the Grantee or one or more of these persons own 100% of the voting interest.

2.7

Tax Obligations.

(a)

Withholding. As a condition to the grant, vesting and exercise of this Option and as further set forth in Article 19 of the Plan,

Grantee hereby agrees to make adequate arrangements satisfactory to the Company for the satisfaction of (and will indemnify the Company

and any Subsidiary or Affiliate for) any applicable taxes or tax withholdings, social contributions, required deductions, or other payments,

if any (“Tax-Related Items”), which arise upon the grant, vesting or exercise of this Option, the lapse of

any substantial risk of forfeiture to which any of the shares of Common Stock are subject at the time of exercise, ownership or disposition

of Shares, receipt of dividends, if any, or otherwise in connection with this Option or the Shares, whether by withholding, direct payment

to the Company, or otherwise as permitted by the Company in its sole discretion. With the Company’s consent, these arrangements

may include withholding Shares that otherwise would be issued to the Grantee pursuant to the exercise of this Option. The Company may

refuse to honor the exercise and refuse to deliver Shares if such withholding amounts are not delivered at the time of exercise. Regardless

of any action the Company or any Subsidiary or Affiliate takes with respect to any or all applicable Tax-Related Items, you acknowledge

and agree that the ultimate liability for all Tax-Related Items is and remains Grantee’s responsibility and may exceed any amount

actually withheld by the Company or any Subsidiary or Affiliate. You further acknowledge and agree that you are solely responsible for

filing all relevant documentation that may be required in relation to this Option or any Tax-Related Items (other than filings or documentation

that is the specific obligation of the Company or any Subsidiary or Affiliate pursuant to applicable law), such as but not limited to

personal income tax returns or reporting statements in relation to the grant, vesting or exercise of this Option, the holding of Shares

or any bank or brokerage account, the subsequent sale of Shares, and the receipt of any dividends. You further acknowledges that the

Company makes no representations or undertakings regarding the treatment of any Tax-Related Items and does not commit to and is under

no obligation to structure the terms or any aspect of the Option to reduce or eliminate Grantee’s liability for Tax-Related Items

or achieve any particular tax result. You also understands that applicable laws may require varying Share or option valuation methods

for purposes of calculating Tax-Related Items, and the Company assumes no responsibility or liability in relation to any such valuation

or for any calculation or reporting of income or Tax-Related Items that may be required of you under applicable laws. Further, if you

have become subject to Tax-Related Items in more than one jurisdiction, you acknowledges that the Company or any Subsidiary or Affiliate

may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

-8-

(b)

Notice of Disqualifying Disposition of ISO Shares. If this Option is an ISO, and if the Grantee sells or otherwise disposes of

any of the Shares acquired pursuant to the exercise of the ISO on or before the later of (i) the date two years after the Grant Date,

or (ii) the date one year after the date of exercise, the Grantee shall immediately notify the Committee in writing of such disposition.

The Grantee may be subject to income tax withholding by the Company on the compensation income recognized by the Grantee.

2.8

Special Conditions.

(a)

ISO Employment. If Grantee’s Option is intended to be an Incentive Stock Option: Note that to obtain the federal income

tax advantages associated with an Incentive Stock Option, the Code requires that at all times beginning on the Date of Grant and ending

on the day three (3) months before the date of Grantee’s Option’s exercise, you must be an employee of the Company or an

Affiliate, except in the event of Grantee’s death or Disability. The Company has provided for extended exercisability of Grantee’s

Option under certain circumstances for Grantee’s benefit but cannot guarantee that the Option will necessarily be treated as an

Incentive Stock Option if you continue to provide services to the Company or an Affiliate as a consultant or director after your employment

terminates or if you otherwise exercise the Option more than three (3) months after the date your employment with the Company or an Affiliate

terminates.

(b)

Special Termination Period if the Grantee Subject to Section 16(b). If a sale within the applicable termination period

set forth in Section 1 of Shares acquired upon the exercise of this Option would subject the Grantee to suit under Section 16(b) of the

Exchange Act, this Option shall remain exercisable until the earliest to occur of (i) the tenth day following the date on which a sale

of such shares by the Grantee would no longer be subject to such suit, (ii) the 190th day after the Grantee’s Termination of Service,

or (iii) the Expiration Date.

(c)

Special Termination Period if the Grantee Subject to Blackout Period. The Company has established an Insider Trading Policy (as

such policy may be amended from time to time, the “Policy”) relative to trading while in possession of material,

non-public information. The Policy prohibits officers, directors, employees, and consultants of the Company and its subsidiaries from

trading in securities of the Company during certain “Blackout Periods” as described in the Policy. If the last

day of the termination period set forth in Section 1 is during such a Blackout Period, then this Option shall remain exercisable until

14 days after the first date that there is no longer in effect a Blackout Period applicable to the Grantee.

-9-

2.9

Restrictions on Resale; Lock-up Agreement. The Grantee shall not sell any Shares at a time when applicable law, Company

policies or an agreement between the Company and its underwriters prohibit a sale. This restriction shall apply as long as the Grantee

is a Service Provider and for such period after the Grantee’s Termination of Service as the Committee may specify. Without limiting

the foregoing, in connection with any underwritten public offering of shares of Common Stock made by the Company pursuant to a registration

statement filed under the Securities Act, the Grantee shall not offer, sell, contract to sell, pledge, hypothecate, grant any option

to purchase or make any short sale of, or otherwise dispose of any shares of Common Stock (including but not limited to Shares subject

to this Option) or any rights to acquire shares of the Company for such period beginning on the date of filing of such registration statement

with the Securities and Exchange Commission and ending at the time as may be established by the underwriters for such public offering;

provided, however, that such period shall end not later than 180 days from the effective date of such registration statement. The foregoing

limitation shall not apply to shares registered for sale in such public offering.

2.10

Termination for Cause. In the event Grantee’s Termination of Service is (x) for Cause, or (y) as a result of a termination

initiated by you under or in anticipation of circumstances that would constitute Cause, or (z) due to you voluntarily departing and,

after such voluntary departure, you at any time engage, directly or indirectly, in behavior that would constitute Cause or you breach

in any material respect any provision of this Agreement or any Company Agreement, this Option (including any vested portion thereof)

shall immediately terminate and be forfeited in its entirety upon first notification to you of such termination for Cause. If Grantee’s

service is suspended pending an investigation of whether Grantee’s Termination of Service will be terminated in accordance with

clause (x), (y) or (z) above, all Grantee’s rights under this Option, including the right to exercise this Option, shall be suspended

during the suspension period.

2.11

Competition with the Company. In order to protect the Company’s goodwill and investments in research and development

and Customer and business relationships and to prevent the disclosure of the Company’s confidential and trade secret information,

thereby promoting the long-term success of the Company’s business, you agree to the following:

(a)

Restricted Activities.

(i)

During your employment, you will not, without the prior written consent of the Company, directly or indirectly engage in Competitive

Activities;

(ii)

During your employment and for any restricted period set forth in a Company Agreement to which you are a party (a “Restricted

Period”), you will not breach or violate any of the provisions of such Company Agreement; and

(iii)

For a period of twenty-four (24) months following your Termination Date, Grantee will not, without the prior written consent of the Company,

directly or indirectly perform, or assist others to perform, work for a Competitor in a position in which you could disadvantage the

Company or advantage the Competitor through (A) Grantee’s disclosure or use of the Company’s confidential or trade secret

information and/or (B) Grantee’s use of the Company’s Customer relationships and goodwill.

(b)

Rescission and Forfeiture. You understand and agree that if the Company determines you have violated any of the provisions of

Section 2.11(a), including with respect to any Company Agreement, then, in addition to injunctive relief, damages, and all other equitable

and legal rights and remedies:

(i)

this Option (whether or not vested) shall be terminated and forfeited for no consideration on the earliest date on which you are first

in violation of Section 2.11(a) or any Company Agreement that you have with the Company; and

-10-

(ii)

upon the Company’s demand, you shall immediately deliver to the Company (1) a number of shares of Common Stock equal to the number

of shares of Common Stock with respect to which you exercised the Option (for the avoidance of doubt, without reduction for any shares

of Common Stock that may have been withheld and/or sold to satisfy applicable withholding taxes) within the twelve (12) month period

of time immediately preceding the earliest date on which you are first in violation of Section 2.11(a) or any Company Agreement, less

(2) the number of shares of Common Stock withheld upon exercise to satisfy the Option purchase price (or, if you paid the purchase price

in cash, the number of shares that would have been withheld had the purchase price been paid via cashless exercise). To the extent that

you do not, as of the date of the Company’s demand for repayment, hold a number of shares of Common Stock sufficient to satisfy

the obligation set forth in the preceding sentence, you shall pay the Company an amount in cash equal to (x) (i) the number of shares

required to be delivered by you pursuant to the preceding sentence, less (ii) the number of shares actually delivered by you pursuant

to the preceding sentence, multiplied by (y) the Fair Market Value per share of Common Stock as of the business day immediately preceding

the date of the Company’s demand for repayment. You agree to deliver and execute such documents (including, if applicable, share

certificates) as the Company may deem necessary to effect the repayment obligations referred to in this Section 2.11(b)(ii).

(c)

Injunctive Relief. You hereby acknowledge and agree that in the event of any breach of this Agreement by you, including, without

limitation, the actual or threatened breach of any Section 2.11(a) or disclosure or unauthorized use of Confidential Information without

the prior express written consent of the Company, the Company would suffer irreparable injury such that no remedy at law would adequately

protect or appropriately compensate the Company for such injury. Accordingly, you agree that the Company shall have the right to seek

enforcement of this Agreement and any of its provisions by injunction, specific performance or other equitable relief, without prejudice

to any other rights and remedies that the Company may have for a breach of this Agreement, and without the necessity of posting any bond

or other security.

(d)

Non-Exclusive Remedies. You understand and agree that the remedies set forth in Section 2.11(b) and Section 2.11(c) shall not

be the Company’s exclusive remedies in the event of a breach of the obligations set forth in Section 2.11(a) or other obligation

in any applicable Company Agreement, and that the Company reserves all other rights and remedies available to it at law or in equity.

(e)

Severability of Covenants. You acknowledge and agree that as to you the covenants set forth in this Section 2.11 are reasonable

and valid in geographical and temporal scope and in all other respects. If any court determines that any of such covenants, or any part

thereof, is invalid or unenforceable as to you or to any other holder of shares of the Company, the remainder of such covenants shall

not thereby be affected and shall be given full effect as to you, without regard to the invalid portions.

(f)

Blue-Penciling. If any court determines that any of the covenant set forth in this Section 2.11, or any part thereof, is unenforceable

as to you or to any other stockholder because of the duration or geographic scope of such provision, such court shall have the power

to reduce the duration or scope of such provision, as the case may be, as to you and, in its reduced form, such provision shall then

be enforceable.

-11-

2.12

Certain Definitions. For the purposes of this Agreement:

“Cause”

means, notwithstanding anything to the contrary set forth in the Plan, your “Termination of Service” by the Company for “Cause”

pursuant any Company Agreement with the Company or if you are not party to a Company Agreement that includes a definition of “Cause”,

your Termination of Service because of any of the following circumstances, acts or omissions, as determined jointly by the disinterested

member of the Board of the Company: (A) a pattern of failure to satisfactorily perform Grantee’s duties, (B) one or more acts of

insubordination, or willful failure or refusal to perform duties or carry out directives assigned by the Company or a Subsidiary for

which Grantee provides services, (C) one or more acts of dishonesty, including without limitation, theft or misappropriation of funds

or assets of the Company or a Subsidiary, including intellectual property; (D) commission of any acts involving moral turpitude, deceit,

embezzlement, fraud, misappropriation of funds, breach of fiduciary duty or any other act of dishonesty committed by Grantee or at Grantee’s

direction, or a conviction of, or guilty or nolo contendere plea by Grantee to any felony or any crime involving any of the aforementioned

acts, or entry into by Grantee of any consent decree with, or becoming subject to an order of, the Securities Exchange Commission, the

Financial Industry Regulatory Authority or a regulatory or self-regulatory organization which legally prevents or restricts Grantee from

providing services to the Company or a Subsidiary thereof, (E) one or more acts of willful misconduct in violation of the Company’s

Code of Conduct, Insider Trading Policy or other Company policy, (F) a material breach by Grantee of his obligations under this Agreement,

(G) breach or threatened breach of the confidentiality provisions or the restrictive covenants contained in this Agreement or any of

the provisions of a Company Agreement, (H) a material violation of any law, rule, regulation or by-law of any governmental authority

(state, federal or foreign), any securities exchange or association or other regulatory or self-regulatory body or agency applicable

to the Company or any of its Subsidiaries, (I) the habitual abuse of alcohol or any illegal substance or (J) participation or involvement

in intentional or negligent conduct which could subject the Company (or any of its affiliates) to risk or exposure under any local, state,

or federal law relating to harassment or discrimination based upon race, age, sex, disability, or any other protected status, or commission

of any intentional violation of any written policy of the Company adopted from time to time with respect to any such law. Cause shall

not exist to terminate Grantee’s employment under subsection (A) or (I) above unless written notice providing a detailed statement

of the facts and circumstances that, in the opinion of the Company, constitute Cause is provided to Grantee and Grantee is afforded such

reasonable period of time, which shall not be less than ten (10) business days after such notice, to cure (if curable), except that if

complying with such a directive or other curative action is necessary to respond to a regulatory authority or to avoid material economic

harm and, in each case, failure of Grantee to follow such directive or take other curative action within such ten business day period

shall be prejudicial to the Company or a Subsidiary, then such cure period may be, in the good faith determination of the Company, less

than ten business days, so long as not less than a reasonable period of time, as may be necessary to avoid material economic harm and

prejudice to the Company or a Subsidiary from that which would be experienced by the Company or its Subsidiary if such a cure period

was longer. If, following Grantee’s termination of employment hereunder for other than Cause, it is determined in good faith by

the Board that Grantee’s employment could have been terminated for Cause for the reasons set forth in clause (C), (D), (E) or (G)

above, in each case to the extent that such conduct involves or relates to the Company or any of its Subsidiaries and occurs prior to

such termination, Grantee’s employment shall be deemed to have been terminated for Cause retroactively to the date of termination.

“Company

Agreement” means any employment agreement, consulting agreement, proprietary rights agreement, invention assignment or

work for hire agreement, confidentiality agreement, non-competition agreement, non-solicitation agreement, restrictive covenant agreement

or similar agreement with or for the benefit of the Company, including the PIICA, Covenant Agreement and other On-Boarding Document required

to be entered into by Grantee with the Company in connection with Grantee’s employment or the grant of this Option or other equity

incentive.

-12-

“Competitor”

means any person or entity including, but not limited to, you or anyone acting on your behalf, that is engaged or preparing to be engaged

in the research, development, production, manufacturing, marketing or selling of, or consulting on, any product, process, technology,

device, machine, invention or service in existence or under development that resembles, competes with, may now or in the future compete

Tax Consequences.

(a)

You hereby agree that the Company does not have a duty to design or administer the Plan or its other compensation programs in a manner

that minimizes your tax liabilities. You will not make any claim against the Company, or any of its officers, directors, employees or

Affiliates related to tax liabilities arising from your Option or your other compensation. In particular, you acknowledge that this Option

is exempt from Section 409A of the Code only if the exercise price per share specified in the Notice of Stock Option Grant is at least

equal to the “fair market value” per share of the Common Stock on the Date of Grant and there is no other impermissible deferral

of compensation associated with the Option.

(b)

Section 409A. The intent of the parties is that payments and benefits under this Agreement shall be exempt from or shall comply

with Section 409A of the Internal Revenue Code of 1986, as amended, and the regulations and guidance issued thereunder (“Section

409A”), to the extent subject thereto, and accordingly, to the maximum extent permitted, this Agreement shall be interpreted

and administered to be in compliance therewith or exempt therefrom, as applicable. Notwithstanding anything to the contrary in the Plan

or this Agreement, the Company reserves the right to revise this Agreement as it deems necessary or advisable, in its sole discretion

and without your consent, to comply with Section 409A or to otherwise avoid imposition of any additional tax or income recognition under

Section 409A. However, the Company makes no representation that the Option is not subject to Section 409A nor makes any undertaking to

preclude Section 409A from applying to the Option. The Company shall not have any liability under the Plan or this Agreement for any

taxes, penalties or interest due on amounts paid or payable pursuant to the Plan or this Agreement, including any taxes, penalties or

interest imposed under Section 409A. For purposes of the Plan and this Agreement, to the extent necessary to avoid accelerated taxation

and/or tax penalties under Section 409A, a termination of employment shall not be deemed to have occurred for purposes of settlement

of any portion of the Option unless such termination constitutes a “separation from service” within the meaning of Section

409A and, for purposes of any such provision of this Agreement, references to a “termination,” “termination of employment”

or similar terms shall mean “separation from service.”

2.15

Data Privacy. Grantee hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or

other form, of his or her personal data as described in this Agreement and any other award materials by and among, as applicable, the

Grantee’s employer, the Company and any Subsidiary or affiliate of the Company for the exclusive purpose of implementing, administering

and managing Grantee’s participation in the Plan or with respect to the Shares. Grantee understands that the Company and the Grantee’s

employer may hold certain personal information about him or her, including, but not limited to, Grantee’s name, home address and

telephone number, date of birth, social security number or other identification number, salary, nationality, job title, any shares of

stock or directorships held in the Company, details of all Shares or any other entitlement to shares of stock awarded, canceled, exercised,

vested, unvested or outstanding in Grantee’s favor, for the exclusive purpose of implementing, administering and managing the Plan

or with respect to the Shares (“Data”).

-14-

Grantee

understands that Data may be transferred to a stock plan service provider as may be selected by the Company from time to time, to assist

the Company with the implementation, administration and management of the Plan. Grantee understands that the recipients of the Data may

be located in the United States or elsewhere, and that the recipients’ country (e.g., the United States) may have different data

privacy laws and protections than Grantee’s country. Grantee understands that he or she may request a list with the names and addresses

of any potential recipients of the Data by contacting Grantee’s local human resources representative. Grantee authorizes the Company,

and any possible recipients which may assist the Company (presently or in the future) with implementing, administering and managing the

Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purpose of implementing, administering

and managing Grantee’s participation in the Plan or with respect to the Shares. Grantee understands that Data will be held only

as long as is necessary to implement, administer and manage Grantee’s participation in the Plan. Grantee understands that he or

she may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments

to Data or refuse or withdraw the consents herein, in any case without cost, by contacting in writing Grantee’s local human resources

representative. Grantee understands, however, that refusing or withdrawing his or her consent may affect Grantee’s ability to participate

in the Plan. For more information on the consequences of Grantee’s refusal to consent or withdrawal of consent, Grantee understands

that he or she may contact his or her local human resources representative.

2.16

No Guarantee of Continued Service. The vesting of the Option pursuant to the Vesting Schedule hereof is earned only by

continuing as a Service Provider at the will of the Company (and not through the act of being hired, being granted an Option, or purchasing

Shares hereunder). This Option Agreement, the transactions contemplated hereunder, and the Vesting Schedule constitutes neither an express

nor an implied promise of continued engagement as a Service Provider for the vesting period, for any period, or at all, and shall not

interfere with Grantee’s right or the Company’s right to terminate Grantee’s relationship as a Service Provider at

any time, with or without Cause.

2.24

No Acquired Rights or Employment Rights.

(a)

No Right to Future Employment. Nothing contained in your Option is intended to constitute or create a contract of employment or

other service, nor shall it constitute or create the right to remain associated with or in the employ of the Company or any Subsidiary

or Affiliate for any particular period of time, and nothing in your Option will be deemed to create in any way whatsoever any obligation

on your part to continue in the employ or other service of the Company or an Affiliate, or of the Company or an Affiliate to continue

your employment. In addition, nothing in your Option will obligate the Company or an Affiliate, their respective stockholders, boards

of directors, officers or employees to continue any relationship that you might have as a Director or Consultant for the Company or an

Affiliate.. This Agreement shall not interfere in any way with the right of the Company or any Subsidiary or Affiliate to terminate your

employment or service at any time, subject to applicable laws.

(b)

No Acquired Rights. Grantee acknowledges and agrees as follows: (a) the grant of this Option is voluntary and occasional and does

not create any contractual or other right to receive future grants of Options, other awards under the Plan or benefits in lieu of Options,

even if Options have been granted repeatedly in the past, and all decisions with respect to future grants of Options or other awards

under the Plan, if any, will be at the sole discretion of the Company; (b) the grant of the Option is exceptional, voluntary and occasional

and does not create any contractual or other right to receive future grants of options, or benefits in lieu of options, even if options

have been granted in the past; (c) unless otherwise agreed with the Company, the Option and the shares of Common Stock subject to the

Option, and the income and value of same, are not granted as consideration, or in connection with, the service you may provide as a director

of the Company; (d) the future value of the underlying shares of Common Stock is unknown, indeterminable and cannot be predicted with

certainty; (e) if the underlying shares of Common Stock do not increase in value, the Option will have no value; (f) if you exercise

the Option and acquire shares of Common Stock, the value of such shares of Common Stock may increase or decrease in value, even below

the purchase price; (g) no claim or entitlement to compensation or damages shall arise from forfeiture or recoupment of the Option resulting

later found to be invalid or in breach of employment laws in the jurisdiction where you are employed or the terms of your employment

agreement, if any); (h) you shall seek all necessary approvals under, make all required notifications under, and comply with all laws,

2.

Investment and Taxation Representations. In connection with the purchase of the Shares, Grantee represents to the Company

the following:

(a)

Investment Representation. In connection with the purchase of the Shares, Grantee is purchasing the Shares for investment for

Grantee’s own account only and not with a view to, or for resale in connection with, any “distribution” thereof within

the meaning of the Securities Act or under any applicable provision of state law. Grantee does not have any present intention to transfer

the Shares to any other person or entity. Grantee agrees that the Grantee will not, directly or indirectly, offer, transfer, sell, pledge,

hypothecate or otherwise dispose of any of the Shares (or solicit any offers to buy, purchase or otherwise acquire or take a pledge of

any of the Shares), except in compliance with (i) the Securities Act, and the rules and regulations of the Securities and Exchange Commission

thereunder, (ii) applicable state and non-U.S. securities or “blue sky” laws and (iii) and the provisions of this Agreement.

Grantee further understands, acknowledges and agrees that none of the Shares or any interest therein or any rights relating thereto may

be transferred, sold, pledged, hypothecated or otherwise disposed of unless (x) the provisions of this Agreement shall have been complied

with and (y) such disposition is exempt from the provisions of Section 5 of the Securities Act or is pursuant to an effective registration

statement under the Securities Act and is exempt from (or in compliance with) applicable state securities or “blue sky” laws.

Any attempt by Grantee, directly or indirectly, to offer, transfer, sell, pledge, hypothecate or otherwise dispose of any Shares, or

any interest therein, or any rights relating thereto, without complying with the provisions of this Agreement, shall be void and of no

effect.

(b)

Ability to Bear Risk. (i) Grantee’s financial situation is such that Grantee can afford to bear the economic risk of holding

the Shares for an indefinite period of time and (ii) Grantee can afford to suffer the complete loss of Grantee’s investment in

the Shares. Grantee confirms that none of the Company, any officers or board members, nor any other person or entity, guarantees the

success of the investment in the Shares or that substantial losses will not be incurred on such investment. Grantee further acknowledges

and understands that the securities must be held indefinitely unless they are subsequently registered under the Securities Act or an

exemption from such registration is available. Grantee further acknowledges and understands that while the shares of Common Stock are

currently registered under the Securities Act, the Company is under no obligation to Grantee to continue registration of its Common Stock.

(c)

Securities Laws Matters. Grantee is familiar with the provisions of Rule 144, promulgated under the Securities Act (“Rule

144”), which, in substance, permits limited public resale of “restricted securities” such as the Shares acquired,

directly or indirectly, from the issuer of the securities (or from an affiliate of such issuer), in a non-public offering subject to

the satisfaction of certain conditions. Grantee acknowledges receipt of advice from the Company that (i) the Company has made no covenant

to continue to make Rule 144 available, (ii) if and when the Shares may be disposed of without registration in reliance upon Rule 144,

such disposition can be made only in limited amounts and in accordance with the terms and conditions of such Rule, (iii) if the exemption

afforded by Rule 144 is not available, public sale of the Shares without registration will require the availability of another exemption

under the Securities Act, and (iv) a notation shall be made in the appropriate records of the Company indicating that the Shares are

subject to restrictions on transfer and appropriate stop transfer instructions will be issued to its transfer agent with respect to the

Shares. Grantee further understands that the Company provides no assurances as to whether he or she will be able to resell any or all

of the Shares pursuant to Rule 144, which rule requires, among other things, that the Company be subject to the reporting requirements

of the Securities Exchange Act of 1934, as amended, that resales of securities take place only after the holder of the Shares has held

the Shares for certain specified time periods, and under certain circumstances, that resales of securities be limited in volume and take

place only pursuant to brokered transactions. If Rule 144 is not available, (A) it is not anticipated that there will be any public market

for the Shares, and (B) the Grantee must continue to bear the economic risk of the investment in the Shares unless such Shares are subsequently

registered under the Securities Act and such state or non-U.S. securities laws or an exemption from such registration is available.

Access to Information. Grantee is aware of the Company’s business affairs and financial condition, properties, operations

and prospects, and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the

Shares, and has been granted the opportunity to ask questions of, and receive answers from, representatives of the Company concerning

the Company, and to obtain any additional information that Grantee deems necessary to verify the accuracy of the information so provided.

Grantee’s knowledge and experience in financial and business matters is such that Grantee is capable of evaluating the merits and

risks of the Shares. Grantee acknowledges that the Company has filed with or furnished to, as applicable, the Securities and Exchange

Commission (“SEC”) various registration statements, prospectuses, reports, schedules, forms, statements, and

other documents (including exhibits and all other information incorporated by reference), all of which are available and accessible by

Grantee at www.sec.gov or through the website of the Company, and Grantee has carefully reviewed the same to the extent Grantee

deems appropriate. In furtherance of the foregoing, Grantee represents and warrants that Grantee has relied upon Grantee’s own

independent appraisal and investigation and the advice of Grantee’s own counsel, tax advisors and other advisors, regarding the

risks of an investment in the Company and Grantee will continue to bear sole responsibility for making his or her own independent evaluation

and monitoring of the risks of Grantee’s investment in the Company.

PERFORMANCE INCENTIVE SUB-PLAN

to

the

2020

EQUITY INCENTIVE PLAN

1. Purpose

of Sub-Plan. The Board of Directors of Milestone Scientific Inc. (the “Company”) established the Amended

and Restated 2020 Equity Incentive Plan (the “2020 Plan”). The terms of this Sub-Plan, as amended from time to time,

shall, subject to the provisions hereof, constitute a Sub-Plan of the 2020 Plan (this “Sub-Plan”). Through the 2020

Plan, the Company established a framework to aid the Company in attracting, retaining, motivating and rewarding employees and Non-Employee

Directors of, and consultants to, the Company or its Subsidiaries or affiliates, to provide for equitable and competitive compensation

opportunities, to recognize individual contributions and reward achievement of Company goals, and promote the creation of long-term value

for stockholders by closely aligning the interests of Participants with those of stockholders.

The

2020 Plan authorized the Committee to grant shares of Common Stock as a bonus, or to grant shares of Common Stock or other awards in

lieu of obligations to pay cash, and to grant such other awards that may be denominated or payable in, valued in whole or in part by

reference to, or otherwise based on, or related to, shares of Common Stock, as deemed by the Committee to be consistent with the purposes

of the Plan.

The

purpose of this Sub-Plan is to provide a framework for the grant of similar awards under the 2020 Plan, to promote the long-term growth

and profitability of the Company and its Subsidiaries by providing certain officers, employees and executive directors of the Company

and its Subsidiaries with long-term incentives to maximize stockholder value and otherwise contribute to the success of the Company,

through a fixed pool of performance-based restricted stock units allocated to certain performance milestones, and to cause all awards

under this Sub-Plan (each, an “Award” and collectively, “Awards”) to be exempt from or comply with

Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and to comply with certain other provisions

and exemptions under U.S. law. This Sub-Plan supplements, and shall be read in conjunction with the 2020 Plan, and is subject to the

terms and conditions of the 2020 Plan; provided, that to the extent that the terms and conditions of the 2020 Plan differ from or conflict

with, the terms or conditions of this Sub-Plan, the terms and conditions of this Sub-Plan shall prevail.

2. Definitions.

For the purposes of this Sub-Plan, the definitions set out in the 2020 Plan shall apply to this Sub-Plan as such definitions apply to

the 2020 Plan and in addition the terms set forth on Appendix A shall have the meanings ascribed thereto (unless the context requires

otherwise).

3. Administration.

(a) Committee.

This Sub-Plan shall be administered by the Committee, if any; provided that the Board may, in its discretion, at any time and from time

to time, resolve to administer this Sub-Plan, in which case the term “Committee” shall be deemed to mean the Board

for all purposes herein. Subject to the provisions of this Sub-Plan, the Committee shall be authorized to (i) select persons to participate

in this Sub-Plan, (ii) determine the substance of grants made under this Sub-Plan to each Participant, and the conditions and restrictions,

if any, subject to which such grants will be made, (iii) certify that the conditions and restrictions applicable to any grant have been

met, (iv) subject to the terms of Section 22, modify the terms of grants made under this Sub-Plan, (v) interpret this Sub-Plan and grants

made thereunder, (vi) make any adjustments necessary or desirable in connection with grants made under this Sub-Plan to eligible Participants

and (vii) adopt, amend, or rescind such rules and regulations, and make such other determinations, including with respect to competitive

activities, competition and other events giving rise to forfeiture, for carrying out this Sub-Plan as it may deem appropriate. Decisions

of the Committee on all matters relating to this Sub-Plan shall be in the Committee’s sole discretion and shall be conclusive and

binding on all parties. The validity, construction, and effect of this Sub-Plan and any rules and regulations relating to this Sub-Plan

shall be determined in accordance with applicable federal and state laws and rules and regulations promulgated pursuant thereto and the

rules and regulations of the Trading Market.

(b) Expenses.

The expenses of this Sub-Plan shall be borne by the Company. This Sub-Plan shall not be required to establish any special or separate

fund or make any other segregation of assets to assume the payment of any award under this Sub-Plan, and rights to the payment of such

Awards shall be no greater than the rights of the Company’s general creditors.

(c) Discretion.

Without limiting the generality of the other provisions of this Sub-Plan, the Committee may, at any time or from time to time, and on

such terms and conditions (that are consistent with and not in contravention of the other provisions of this Sub-Plan) as the Committee

may, in its sole discretion, determine, enter into agreements (or take other actions with respect to Awards) for new Awards containing

terms (including performance measures) more (or less) favorable than outstanding similar Awards.

4. Eligibility. The Chief Executive Officer, the President, Chief Financial Officer, each executive officer and such other senior officers of the Company and directors of the Company as the Committee may designate (the executive officers, designated senior officers, and directors, if any, together the “Eligible Persons”) will be eligible to participate in this Sub-Plan, but no individual will have a right to participate. Awards may be granted to such Eligible Persons of the Company and its Subsidiaries as determined in the sole discretion of the Committee. Designation as an Eligible Person does not guarantee receipt of an Award, and the Committee may limit participation to selected roles based on governance or compensation objectives.

5. Shares

Reserved for Issuance; RSUs.

(a) Shares

Authorized.

(1) Subject

to stockholder approval in accordance with the requirements of the rules of the Trading Market or as required by the Code or other applicable

law, the total aggregate number of shares of Common Stock (the “Shares”) that may be issued or transferred under this

Sub-Plan in settlement of Awards is 17,234,635, subject to adjustment as described below, which number of Shares may be amended by the

Committee prior to the time, and if, this Sub-Plan is submitted to the Company’s stockholders for approval (such number, as adjusted

and/or amended, the “Aggregate Pool”). The Shares may be authorized but unissued shares of Common Stock or re-acquired

shares of Common Stock, including shares purchased by the Company on the open market for purposes of this Sub-Plan. For administrative

purposes, when the Committee makes a grant of an Award payable in Common Stock, the Committee shall reserve shares of Common Stock equal

to the maximum number of Shares that may be payable under the Award. If any PRSUs are forfeited or terminated, or otherwise is not paid

in full, the shares subject to such PRSUs which have not been issued shall again be available for purposes of this Sub-Plan; provided,

that the shares subject to such Award shall not be re-allocated or granted to an existing Participant, but may be granted to a new Participant

under this Sub-Plan. Shares of Common Stock withheld for purposes of satisfying the Company’s applicable tax withholding obligations

with respect to an Award granted under this Sub-Plan, if any, shall not be available for re-issuance or transfer under this Sub-Plan.

To the extent that any RSUs are settled in cash and not Shares, such grants of RSUs shall not count against the share limits set forth

above. If any PRSUs are forfeited or terminated, or otherwise is not paid in full, or for other Shares not subjected to an Award, the

shares subject to such forfeited or terminated PRSUs or not underlying a PRSU may be recaptured by the 2020 Plan for disposition thereunder

in the Committee’s discretion.

(2)

Notwithstanding anything to the contrary in Section 5(a)(1) above, the Committee may in its discretion utilize shares of Common Stock

duly authorized for issuance under the terms of the Company’s 2020 Plan, or a successor or replacement equity plan to the 2020

Plan (a “Successor Equity Plan”), for grants of Awards in satisfaction of any portion or all of the Awards granted

under the terms of this Sub-Plan. In this case, (i) such Awards shall be subject to the terms of the 2020 Plan or Successor Equity Plan,

as well as the terms of this Sub-Plan; and (ii) the terms of the 2020 Plan or Successor Equity Plan regarding number of shares, share

counting, and fungible share pool set forth in Section 5 of the 2020 Plan or similar provisions of a Successor Equity Plan shall govern

in lieu of Section 5(a)(1) of this Sub-Plan.

(b) Adjustments.

In the case that shares of Common Stock are authorized exclusively for use under the terms of this Sub-Plan, if there is any change in

the number or kind of shares of Common Stock outstanding (i) by reason of a stock dividend, spinoff, recapitalization, stock split, or

combination or exchange of shares, (ii) by reason of a merger, reorganization or consolidation, (iii) by reason of a reclassification

or change in par value, or (iv) by reason of any other extraordinary or unusual event affecting the outstanding Common Stock as a class

without the Company’s receipt of consideration, or if the value of outstanding shares of Common Stock is substantially reduced

as a result of a spinoff or the Company’s payment of an extraordinary dividend or distribution, the maximum number of shares of

Common Stock available for issuance under this Sub-Plan, the maximum number of shares of Common Stock for which any individual may receive

pursuant to Awards in any year, the number of shares covered by outstanding Award grants, the kind of shares to be issued or transferred

under this Sub-Plan, and any applicable performance goals tied to the number of outstanding shares shall be equitably adjusted by the

Committee, in such manner as the Committee deems appropriate, to reflect any increase or decrease in the number of, or change in the

kind or value of, issued shares of Common Stock to preclude, to the extent practicable, the enlargement or dilution of rights and benefits

under this Sub-Plan; provided, however, that any fractional shares resulting from such adjustment shall be eliminated. Any adjustments

to outstanding Awards shall be consistent with Section 409A of the Code, to the extent applicable. Any adjustments determined by the

Committee shall be final, binding and conclusive. If shares of Common Stock authorized under the terms of the 2020 Plan or a Successor

Equity Plan are used for issuance of PRSU grants under the terms of this Sub-Plan, in accordance with Section 5(a)(2) above, Section

5 of the 2020 Plan, or similar provision of a Successor Equity Plan, shall govern the adjustment of shares in respect of outstanding

Awards, in lieu of this Section 5(b). No adjustment shall be made that would increase the intrinsic value of any Award other than adjustments

expressly permitted under the 2020 Plan and applicable law; provided, that no adjustment shall cause any Award to fail to be exempt from

or comply with Section 409A of the Code.

6. Grants of Awards; Creation of Bonus Pools.

(a) Selection

by the Committee of Participants. The Committee may select those Eligible Persons who will receive Awards from time to time during

the first three (3) years of the Performance Period, subject to defeasance of any part of an Award the Performance Milestone of which

is achieved within twelve (12) months after such grant. Following such selection by the Committee, the selected Eligible Persons will

be notified in writing that such person is a participant in this Sub-Plan (each such notified person, a “Participant”)

and such Participant’s percentage participation in each sub-pool created with respect to a Performance Milestone pursuant to Section

6(d) (each, a “Sub-Pool”), for a total of five (5) Participation Percentages, each for a separate Sub-Pool.

(b) Form

of Awards. Each Award under this Sub-Plan shall be in the form of a performance-based restricted stock unit (each a “PRSU”

or “Unit”). The PRSUs shall be issued in series, with each series corresponding to, and entitled to participation

in only, a designated Performance Milestone. Each Participant in a particular Sub-Pool will be eligible to receive such Participant’s

Participation Percentage of that Sub-Pool amount, subject to a Participant’s forfeiture of his or her participation right pursuant

to Section 8.

(c) Performance

Period. Awards will be measured based on a performance period of four (4) years, commencing on January 1, 2026, and ending on December

31, 2029 (the “Performance Period”).

(d) Allocation

to Performance Milestones; Creation of Sub-Pools. If the applicable performance conditions set forth below are satisfied with respect

to any of the following performance milestones (each, a “Performance Milestone” and collectively, the “Performance

Milestones”), the portion of the Aggregate Pool set forth below shall be allocated for bookkeeping purposes into, and there

shall be created for bookkeeping purposes, a Sub-Pool with respect to such Performance Milestone, as follows:

Performance Milestone

Sub-Pool

(percentage of Aggregate Pool)

LTM Net Sales greater than $11.0 million

20%

LTM Net Sales greater than $13.0 million

20%

LTM Net Sales greater than $15.0 million

30%

Market Capitalization of $50 million

15%

Qualified Acquisition consummated

15%

Each

of the above Performance Milestones having as its trigger an amount of LTM Net Sales is referred to as a “Sales Milestone”.

The

following terms shall have the meanings specified:

“LTM

Net Sales” means, without duplication, with respect to a rolling twelve calendar month period immediately preceding the date

of determination, (a) the aggregate gross amount invoiced by or on behalf of the Company and its Subsidiaries for products sold globally

in bona fide, arm’s length transactions with respect to its business lines existing on the date hereof, less (b) (i) deductions

for trade, (ii) discounts, rebates, chargebacks and credits, (iii) allowances, (iv) taxes, (v) duties, (vi) governmental tariffs, (vii)

freight, shipping and freight insurance costs and charges, (viii) returns and (ix) recalls. In the event that the Company shall transfer

products to an Affiliate of the Company and such company retransfers the products to a third party within one year of its receipt, then

the price charged by the Affiliate to third parties shall be included in the Company’s gross sales, and the price charged to such

Affiliate shall not be included within gross sales. If such Affiliate does not retransfer the products within one year, then the higher

of (i) the price charged by the Company to such Affiliate or (ii) the average price charged by the Company to third party customers during

such year or, in the absence of sales to third party customers, the fair market price for the products, shall be included in the Company’s

gross sales, for purposes of calculating LTM Net Sales of the Company hereunder.

“Market

Capitalization” means the total dollar value of the Company’s outstanding shares of Common Stock on the relevant date,

calculated by multiplying the VWACP on the Trading Market for twenty (20) out of thirty (30) consecutive trading days by the total number

of outstanding shares of Common Stock then outstanding. If the Common Stock is not listed or quoted on a Trading Market or VWAP is unavailable,

Market Capitalization shall be determined using the average bid-ask midpoint (or, if unavailable, composite dealer quotations) for twenty

(20) out of thirty (30) consecutive trading days.

“Qualified

Acquisition” means an acquisition of a company or business, by merger, acquisition of assets or equity, or otherwise, having

more than $10 million of revenue, determined in accordance with generally accepted accounting principles consistently applied, in respect

of the four consecutive quarters immediately preceding the closing of such acquisition, as reflected in financial statements of such

company or business audited by an independent auditing firm reasonably acceptable to the Company.

(e) Funding

of Sub-Pools. Each Sub-Pool with respect to which the Performance Milestone has been met and certified as herein provided shall be

funded by the contribution by the Company of that number of Shares equal to the required funding amounts of the Aggregate Pool as set

forth in Section 6(d). In the event (x) stockholders of the Company have not approved the shares of Common Stock reserved for issuance

under the terms of the 2020 Plan prior to the date on which the funding for a Sub-Pool is triggered, or have not approved a sufficient

number of shares of Common Stock to fund such Sub-Pool, (y) the Committee has determined it will not fund the Sub-Pool with shares of

Common Stock authorized under the 2020 Plan or Successor Equity Plan (as such terms are defined herein) as set forth in Section 5(a)(2),

or (z) the Committee has otherwise determined that it is desirable to do so, the Sub-Pool, as applicable, will not be funded in any respect;

provided, that if a Sales Milestone shall not be funded due to a lack of available shares as contemplated in this Section 6(e) and a

Sub-Pool for a subsequent Sales Milestone shall be funded, the Company shall use its reasonable commercial efforts to fund the Sub-Pool

with respect to any previous Sales Milestones not so funded.

(f) Individual

Limit. No one Participant shall, in the aggregate under this Sub-Plan, be granted or allocated more than thirty percent (30%) of

the PRSUs allocated to any Sub-Pool or under this Sub-Plan.

7. Award

Terms and Conditions.

(a) Form

of Payment. All Awards will be in the form of a stock-settled PRSU, as described in Section 6(b), except as set forth below, and

subject to the terms and conditions of an award agreement (consistent with the provisions of this Sub-Plan and, if applicable, the 2020

Plan) provided to the Participant at the time the Award is granted. As set forth below and as shall be memorialized in the award agreement,

portions of the PRSUs may be subject to forfeiture. Each PRSU shall be equivalent to one share of Common Stock and shall entitle the

Participant to receive from the Company at the settlement thereof applicable to such PRSU one share of Common Stock. PRSUs may be granted

without payment of cash or consideration to the Company; provided that Participants shall be required to pay to the Company the aggregate

par value of the shares received from the Company within ten days of the issuance of such shares unless such shares are treasury shares.

(b) Conditions

to Payment of Awards. Prior to the payment of any Award, the Committee will determine whether the Performance Milestone with respect

to the applicable Sub-Pool has been met, and if met the Committee will certify in writing prior to payment pursuant to the compensation

committee certification requirement in Treas. Reg. § 1.162-27(e)(5) that the Performance Milestone goals and any other material

terms were in fact satisfied, therefore triggering the vesting of the applicable Sub-Pool. For the avoidance of doubt, no PRSU shall

vest unless and until the Committee has certified in writing that the applicable Performance Milestone has been achieved. Vesting occurs

only upon such written certification. In addition, no Award will be payable pursuant to this Sub-Plan in the form of stock-settled PRSUs

until stockholder approval of this Sub-Plan has been obtained, unless the Committee has, in its discretion, determined to utilize shares

of Common Stock authorized under the 2020 Plan or a Successor Equity Plan in accordance with Section 5(a)(2). Notwithstanding the foregoing,

any portion or all of the Awards may be payable in cash at the discretion of the Committee (whether or not stockholder approval is obtained

or whether shares of the 2020 Plan or a Successor Equity Plan are utilized). Awards are subject to forfeiture as provided below.

(c) Vesting;

Settlement.

(1) Awards

with respect to a Performance Milestone shall vest upon achievement of such Performance Milestone, subject to Certification, satisfaction

of the service requirement set forth in Section 8 and the other requirements set forth in this Sub-Plan, except that any part of an Award

the Performance Milestone of which (other than with respect to a Qualified Acquisition) is achieved within twelve (12) months after such

grant to a Participant shall be treated 292 as if such Performance Milestone was not so achieved for such Participant.

(2) Following

the Committee’s written certification of a Performance Milestone (“Certification”) and the corresponding vesting

of the related PRSUs, the Company shall settle such vested PRSUs by the later of (i) March 15th of the year following the year in which

such PRSUs vest or (ii) 2½ months after the end of the Company’s taxable year in which such PRSUs vest, in compliance with

the short-term deferral exception rules of Section 409A of the Code, the Participant shall be issued that number of Shares equal to the

number of PRSUs which then vested, subject to Section 10, satisfaction of the service requirement set forth in Section 11, Section 15,

including the Participant making arrangements satisfactory to the Company for the payment of any Federal, state, or local income and

employment taxes in connection with the PRSU’s settlement, and Section 20.

(d) Reallocation.

Notwithstanding anything contained in this Sub-Plan to the contrary, PRSUs allocated to a particular Performance Milestone may be reallocated

away from a Participant, except that no reallocations shall occur within twelve (12) months prior to a Change in Control of the Company

or the achievement of such Performance Milestone. Factors affecting whether and the extent to which Awards or Participation Percentages

of one or more Sub-Pools will be reallocated will include the contribution of the Participant to the applicable Performance Milestone,

including with respect to the Qualified Acquisition or the businesses or customers generating the sales or revenues, as shall be determined

by the Committee. in its sole discretion. Reallocations shall be made based on relative contribution to the applicable performance criteria,

as determined by the Committee. No Participant shall be entitled to any increase in the amount of PRSUs (or Participation Percentage)

in respect of any reduction or other reallocation of PRSUs away from another Participant.

(e) Release.

Notwithstanding anything to the contrary in this Sub-Plan, payment in respect of any Award shall be made within sixty (60) days following

Participant’s Termination of Service, provided that: (i) Participant executes and delivers to the Company a release in favor of

the Company and its Subsidiaries and their respective directors, officers, employees and agents within the time period prescribed by

the Company (which shall not exceed forty-five (45) days following Termination of Service), and such release becomes effective, enforceable

and irrevocable in accordance with its terms; (ii) Participant has complied with the Company Agreements; and (iii) if the sixty (60)

day period following Termination of Service spans two taxable years, subject to Section 7 payment shall be made in the second taxable

year. If Participant fails to execute the release within the prescribed period or the release does not become effective and irrevocable

as provided above, Participant shall forfeit all rights to the Award.

(f) Deferment.

A Participant may elect to defer settlement of PRSUs only to the extent permitted under a Company-sponsored deferred compensation plan

that complies with Section 409A. Any such election must be made in accordance with such plan and applicable law.

8. Termination of Services.

(a)

Service. All vesting shall be subject to, and conditioned on, Participant being (i) if an employee, employed by the Company or

any of its Subsidiaries and designated as an employee of the Company or such Subsidiary on its payroll records on the applicable vesting

date and Participant having remained continuously so employed since the date of grant of the Award, or (ii) if a Non-Employee Director,

serving as a member of the Board or as a member of a board of directors of a Subsidiary on such vesting date (each a “Service

Provider” and the termination of which being a “Termination of Service” and the date thereof, the “Termination

Date”).

(b) Continued

Employment. Except as otherwise provided herein, Participant shall be employed by the Company or any of its Subsidiaries for any

period of time during which Participant is an employee of the Company or any of its Subsidiaries, as determined by the Company in accordance

with its applicable practices, policies and records; provided, that, during such period Participant is (i) in active employment status

with the Company or any of its Subsidiaries, (ii) on a Company-approved leave of absence for up to six months (or greater than six months

if the Participant has a right to reemployment under a statute or contract), or (iii) on leave due to Disability for up to the applicable

period Participant’s job is protected by statute or as approved by the Company. For the avoidance of doubt, Participant shall not

be considered to be employed (x) for any period during which the Participant is not considered to be an employee pursuant to the Company’s

practices, policies and records, (y) during any notice period or salary continuation period required by local law or contract (such as

a “garden leave” or similar period) or any severance period (if the Participant is covered by a severance agreement or arrangement)

or (z) for any period of leave in excess of the periods set forth in clauses (ii) and (iii) above, as applicable. For purposes of Awards,

no such leave may exceed 90 days, unless reemployment upon expiration of such leave is guaranteed by statute or contract. If reemployment

upon expiration of a leave of absence approved by the Company is not so guaranteed, then a Termination of Service of such Participant

shall be deemed to have occurred. Service as a Director, whether or not the Participant receives payment of a director’s fee by

the Company, shall be sufficient to constitute “employment” by the Company for purposes of this Sub-Plan.

(c) Service

Requirement. If a Participant’s service with the Company terminates for any reason prior to the achievement of the applicable

Sub-Pool’s Performance Milestone, the right to any portion of the Award that has not vested prior to the Participant’s Termination

Date shall be forfeited in full and cancelled without consideration as of the Termination Date; provided, that notwithstanding the foregoing,

if a Performance Milestone is achieved while the Participant is a Service Provider and thereafter the Participant experiences a Termination

of Service for any reason (but subject nevertheless to Section 8(d)), any PRSUs relating to Performance Milestones achieved prior to

the Termination Date the achievement of which is thereafter certified by the Committee, such Participant shall not be deemed to have

experienced a Termination of Service solely for purposes of determining entitlement to such Award notwithstanding the Participant’s

Termination of Service prior to Certification, subject to Section 7. Unless otherwise provided in the applicable PRSU award agreement,

any portion of the PRSU that has not vested prior to the date of a Participant’s Termination of Service with the Company for any

reason shall be forfeited as of the Participant’s Termination Date, and neither Participant nor any of his or her successors, heirs,

assigns, or personal representatives will thereafter have any further rights or interests in such forfeited PRSUs.

(d) Discharge

for Cause. In the event Participant’s Termination of Service is (x) for Cause, or (y) as a result of a termination initiated

by the Participant under or in anticipation of circumstances that would constitute Cause, or (z) due to the Participant voluntarily departing

and, after such voluntary departure, the Participant at any time engages, directly or indirectly, in behavior that would constitute Cause

or the Participant breaches in any material respect any provision of this Sub-Plan or any Company Agreement, (i) all Awards granted to

such Participant (including any vested portion thereof) shall immediately terminate and be forfeited in its entirety upon first notification

to the Participant of such termination for Cause, whether or not then vested, and (ii) if the Participant vests in any of his or her

Award, within one year thereafter, the Participant may, in the discretion of the Committee, be required to re-deliver to the Company

the Shares delivered to the Participant (or if such shares have been sold, their aggregate selling price), without regard to any subsequent

increase or decrease in the Fair Market Value of the Common Stock (the “Underlying Share Value”). In addition, the

Company may, in its discretion, deduct from any payment of any kind (including salary or bonus) otherwise due to any such participant

an amount equal to the Underlying Share Value. If the Participant’s service is suspended pending an investigation of whether the

Participant’s Termination of Service will be terminated in accordance with clause (x), (y) or (z) above, all the Participant’s

rights under this Sub-Plan and the related Award shall be suspended during the suspension period.

9. Competition

with the Company. In order to protect the Company’s goodwill and investments in research and development and Customer and

business relationships and to prevent the disclosure of the Company’s confidential and trade secret information, thereby promoting

the long-term success of the Company’s business, the Participant agrees to the following:

(a) Restricted

Activities.

(1) During

the Participant’s employment, the Participant will not, without the prior written consent of the Company, directly or indirectly

engage in any activities (including preparations) which compete with, are intended to compete with, or which otherwise may adversely

affect or interfere with the Company’s business or advantage a Competitor whether immediately or in the future;

(2) During

the Participant’s employment and for any restricted period set forth in a Company Agreement to which the Participant is a party

(a “Restricted Period”), the Participant will not breach or violate any of the provisions of such Company Agreement;

and

(3) For

a period of twenty-four (24) months following the Participant’s Termination Date, the Participant will not, without the prior written

consent of the Company, directly or indirectly perform, or assist others to perform, work for a Competitor in a position in which the

Participant could disadvantage the Company or advantage the Competitor through (A) the Participant’s disclosure or use of the Company’s

confidential or trade secret information and/or (B) the Participant’s use of the Company’s Customer relationships and goodwill.

(b) Rescission

and Forfeiture. The Participant understands and agrees that if the Company determines the Participant has violated any of the provisions

of Section 9(a), including with respect to any Company Agreement, then, in addition to injunctive relief, damages, and all other equitable

and legal rights and remedies without the necessity of showing any actual damages or that money damages would not afford an adequate

remedy, and without the necessity of posting any bond or other security:

(1) All

Awards granted to such Participant (whether or not vested) automatically and without notice shall be terminated and forfeited for no

consideration on the earliest date on which the Participant is first in violation of Section 9(a) or any Company Agreement that the Participant

has with the Company; and

(2) upon

the Company’s demand, the Participant shall immediately deliver to the Company a number of shares of Common Stock equal to the

number of Shares with respect to which the Award was settled (for the avoidance of doubt, without reduction for any shares of Common

Stock that may have been withheld and/or sold to satisfy applicable withholding taxes) within the twelve (12) month period of time immediately

preceding the earliest date on which the Participant is first in violation of Section 9(a) or any Company Agreement. To the extent that

the Participant does not, as of the date of the Company’s demand for repayment, hold a number of shares of Common Stock sufficient

to satisfy the obligation set forth in the preceding sentence, the Participant shall pay the Company an amount in cash equal to (x) the

number of shares required to be delivered by the Participant pursuant to the preceding sentence, multiplied by (y) the Fair Market Value

per share of Common Stock as of the business day immediately preceding the date of the Company’s demand for repayment. The Participant

agrees to deliver and execute such documents (including, if applicable, share certificates) as the Company may deem necessary to effect

the repayment obligations referred to in this Section 9(b)(2).

(c) Non-Exclusive

Remedies. Participant understands and agree that the remedies set forth in Section 9(b) shall not be the Company’s exclusive

remedies in the event of a breach of the obligations set forth in Section 9(a) or other obligation in any applicable Company Agreement,

and that the Company reserves all other rights and remedies available to it at law or in equity.

(d) Severability

of Covenants. Participant acknowledges and agrees that as to such Participant the covenants set forth in this Section 9 are reasonable

and valid in geographical and temporal scope and in all other respects. If any court determines that any of such covenants, or any part

thereof, is invalid or unenforceable as to such Participant or to any other holder of shares of the Company, the remainder of such covenants

shall not thereby be affected and shall be given full effect as to Participant, without regard to the invalid portions.

(e) Blue-Penciling.

If any court determines that any of the covenant set forth in this Section 9, or any part thereof, is unenforceable as to a Participant

or to any other stockholder because of the duration or geographic scope of such provision, such court shall have the power to reduce

the duration or scope of such provision, as the case may be, as to such Participant and, in its reduced form, such provision shall then

be enforceable.

10. Delivery.

(a) Payment

to Specified Employees. Notwithstanding anything to the contrary in this Sub-Plan or in a Participant or Employer payment election,

this Sub-Plan may not make payment, based on Termination of Service to a Participant who, on the date of Termination of Service is a

Specified Employee, earlier than six (6) months following Termination of Service (or if earlier, upon the Specified Employee’s

death), except as permitted under this Section 10(a). This limitation applies regardless of the Participant’s status as a Specified

Employee or otherwise on any other date including the next Specified Employee effective date had the Participant continued to render

services through such date. The Company, operationally and without any direct or indirect Participant election, will elect whether any

payments that otherwise would be payable to the Specified Employee during the foregoing 6-month period: (i) will be accumulated and payment

delayed until the first day of the seventh month that is after the 6-month period; or (ii) will be delayed by six months as to each installment

otherwise payable during the 6-month period. This Section 10(a) does not apply to payments made on account of a domestic relations order,

payments made because of a conflict of interest, or payment of employment taxes, all as described in Treas. Reg. 1.409A-3(i)(2)(i). This

Section 10(a) also does not apply to any reimbursement or in-kind benefit which is severance or separation pay but which is not deferred

compensation.

(b) Installment

Payments.

(1) Settlement

of Awards shall be made in quarterly installments, commencing on the expiration of ninety (90) days or six (6) months (plus a day) after

Termination of Service, as applicable. The number of installments shall be equal to the quotient (rounded up to the nearest whole number)

of the total Fair Market Value of the shares to be delivered at the date of delivery, divided by the number 100,000. The first such installment

is to be made on (or as soon as practicable after) the first day payment is to be made hereunder. Installment payments made after the

first installment shall be made on or about the applicable quarterly anniversary of the first payment date until all required quarterly

installments have been paid.

(2) The

amount of each installment payment shall be determined by dividing the Fair Market Value of the shares to be delivered at the date of

delivery by the number of payments remaining to be paid. Any amounts shall continue to be credited or debited without interest. The final

installment payment shall be equal to the balance of the Fair Market Value of the shares to be delivered at the date of delivery. The

term “payment” shall be treated as a series of separate payments for purposes of Section 409A to the extent applicable.

11. Change in Control.

(a) Awards

Do Not Survive. Upon a Change in Control, all Awards theretofore granted shall be deemed cancelled and terminated, except that Awards

corresponding to Performance Milestones achieved and certified prior to the Change in Control shall vest and settle in accordance with

Section 7, and PRSUs allocated to the Market Capitalization Performance Milestone shall be treated in accordance with Section 11(b).

No vesting or right to any shares or compensation will arise from any achievement of any Performance Milestone occurring after a Change

in Control.

(b) Market

Capitalization Performance Milestone. If (i) there is a Change in Control during the Performance Period, and (ii) if the Market Capitalization

Performance Milestone is reached in connection with, or as a result of, such Performance Milestone, based on the imputed value of the

Company in such Change in Control transaction and without regard to the VWACP or trading day elements of the Market Capitalization definition,

then the Sub-Pool allocated to the Market Capitalization Performance Milestone shall be deemed to be achieved and such sub-Pool vested

and funded, and the PRSUs allocated to the Market Capitalization Performance Milestone shall be treated in accordance with the terms

of this Sub-Plan applicable as if the Market Capitalization Performance Milestone had been achieved as a result of reaching such Performance

Milestone at the end of the Performance Period; provided, however, that in the case of settlement of PRSUs allocated to the Market Capitalization

Performance Milestone, such vested PRSUs shall be exchanged immediately before the consummation of such Change in Control for the amount

and form of consideration distributed to stockholders, if any, in connection with such Change in Control event allocable to, and payable

to Participant in respect of, such Participant’s PRSUs allocated to the Market Capitalization Performance Milestone; provided,

however, that the amount so received in payment or paid shall be limited from time to time to such Participant’s share of the consideration

distributed to stockholders of the Company in connection with such Change in Control event allocable to, and payable to Participant in

respect of, such Performance Milestone, taking into account (and reduced by) any amounts escrowed or withheld, deferred and contingent

consideration, and indemnification payments and other set-offs applicable to the stockholders of the Company.

12. Compliance.

The obligation of the Company to sell or deliver Shares with respect to Awards granted under this 2020 Plan shall be subject to all applicable

laws, rules and regulations, including all applicable federal and state securities laws, and the obtaining of all such approvals by governmental

agencies as may be deemed necessary or appropriate by the Committee. Without limiting the foregoing:

(a) Insider

Trading Policy. No Awards shall be paid in shares of the Company during any blackout period or other period during which Participant

would not be able to purchase or sell shares of Common Stock of the Company in accordance with the Company’s Insider Trading Policy,

including at any time that the Participant shall be in possession of material, non-public information about the Company. In the event

that payment would ordinarily be made but for this Section 12(a), it shall be made as soon as practicable after such condition ceases.

(b) Provisions

Relating to Section 16 of the Exchange Act. With respect to a Participant who is then subject to the reporting requirements of Section

16(a) of the Exchange Act, the Committee shall implement transactions under this Sub-Plan and administer this Sub-Plan in a manner that

will ensure that each transaction by such a Participant is exempt from or otherwise not subject to liability under Rule 16b-3, except

that such a Participant may be permitted to engage in a non-exempt transaction under this Sub-Plan if written notice is given to the

Participant regarding the non-exempt nature of such transaction.

(c) Exchange.

The Company shall impose such restrictions on shares delivered to a Participant hereunder and any other interest constituting a security

as it may deem advisable in order to comply with the Securities Act, the requirements of the Trading Market, any applicable state securities

laws, any provision of the Company’s Certificate of Incorporation or Bylaws, or any other law, regulation, or binding contract

to which the Company is a party.

(d) Parachute

Payments. Unless otherwise specifically provided in the applicable award agreement, notwithstanding anything in this Sub-Plan to

the contrary, the aggregate amount payable to any Participant in respect of Awards shall be reduced by the amount, if any, the Committee

in its sole discretion determines is necessary so as to prevent the payments under this Sub-Plan, together with all other amounts paid

and/or payable to the Participant, in connection with an Award which is also a Change in Control event or otherwise, from constituting

“excess parachute payments” within the meaning of section 280G of the Code and the U.S. Treasury Income Tax Regulations promulgated

thereunder.

13. Restriction

of Transfer. Unless otherwise permitted by the Committee, no Award granted under the terms of this Sub-Plan shall be (i) sold,

transferred or otherwise disposed of, other than by will or the laws of descent and distribution or to a Participant’s Family Member

by gift or a qualified domestic relations order as defined by the Code, (ii) pledged or otherwise hypothecated, or (iii) subject to attachment,

execution or levy of any kind; and any purported transfer, pledge, hypothecation, attachment, execution or levy in violation of this

provision shall be null and void. All provisions of this Sub-Plan shall in any event continue to apply to any Award granted under this

Sub-Plan and transferred as permitted by this Section 13, and any transferee of any such award shall be bound by all provisions of this

Sub-Plan as and to the same extent as the applicable original Participant.

14. Other

Benefit Plans and Arrangements. No payments or entitlements under this Sub-Plan shall be taken into account in computing any

amount of salary or compensation for the purpose of determining any pension, retirement, death or other benefits under (i) any pension,

retirement, life insurance or other benefit plan of the Company or any of its direct or indirect Subsidiaries, or any of their respective

Affiliates, or (ii) any agreement between a Participant and the Company or any of its direct or indirect Subsidiaries, or any of their

respective Affiliates (except as may be expressly provided therein to the contrary), in each case unless required by applicable law.

15. Withholding

Taxes

(a) Company

Requirement. The Company may require, as a condition to the vesting or settlement of any Award or the delivery of certificates for

shares issued hereunder, that the Participant make adequate arrangements satisfactory to the Company for the payment to the Company,

of all Federal, state or local income tax, social insurance, payroll tax, payment on account or other tax-related items related to Participant’s

participation in this Sub-Plan and legally applicable to Participant of any kind required by law to be withheld with respect to any vesting,

settlement or delivery of shares in connection with any Award (“Tax-Related Items”).

(b) Method

of Payment. Prior to any relevant taxable or tax withholding event, as applicable, Participant will pay or make adequate arrangements

satisfactory to the Company to satisfy all Tax-Related Items. In this regard, Participant authorizes the Company and/or Participant’s

other employer (the “Employer”), or their respective agents, at their discretion, to satisfy the obligations with

regard to all Tax-Related Items by one or a combination of the following, in the sole and absolute discretion of the Company:

(1) provided

that at the time of payment the shares of Common Stock of the Company are publicly traded, pursuant to a program developed under Regulation

T as promulgated by the Federal Reserve Board that, prior to the delivery of such shares to Participant, results in either the receipt

of cash (or check) by the Company or the receipt of irrevocable instructions to pay an amount equal to the aggregate Tax-Related Items

to the Company from the sales proceeds; provided, that for such purposes, to better assure the Company and Participant that such sale

will yield to the Company an amount sufficient to satisfy the aggregate Tax-Related Items, the Company shall be entitled to deliver to

the broker Shares having a value required by the broker, which will have a value in excess of the aggregate Tax-Related Items, for sale

as provided herein (any excess to be delivered to Participant after payment in full of the aggregate Tax-Related Items). This manner

of payment is also known as a “broker-assisted exercise”, “same day sale”, or “sell to cover;”

(2) withholding

Shares from any vested Shares, provided that the Company only withholds a number of Shares with a Fair Market Value as of the valuation

date equal to or below the dollar amount of the Tax-Related Items, provided, however, that in order to avoid withholding any fractional

Shares, the Company may round up to the next nearest number of whole Shares, as long as the Company withholds no more than a single whole

Share in excess of the withholding obligation for Tax-Related Items;

(3) withholding

from Participant’s wages or other cash compensation paid to Participant by the Company and/or the Employer; and/or

(4) withholding

from proceeds of the sale of Shares either through a voluntary sale or through a mandatory sale arranged by the Company (on Participant’s

behalf pursuant to this authorization);

it

being understood that (A) the Company will favor receiving from Participants, and may not agree to accept any method does not provide

it with, sufficient cash to pay all applicable taxes, and any and all other amounts required to be withheld under Federal, state, or

local law and other applicable guidance, and (B) the Company does not have to be consistent or treat equally or the same any one or more

Participants, with respect to arrangements for the payment of such Tax-Related Items, and shall be entitled to treat different Participants

differently and the same Participant differently with respect to any deferred compensation.

The

Company or the Employer will remit the total amount withheld for Tax-Related Items to the appropriate tax authorities.

If

the obligation for Tax-Related Items is satisfied by a Regulation T “broker-assisted sale” or by withholding vested shares,

for tax purposes, Participant is deemed to have been issued the full number of vested shares, notwithstanding that a number of the shares

are held back solely for the purpose of paying the Tax-Related Items due as a result of any aspect of Participant’s participation

in this Sub-Plan or an Award.

Finally,

Participant shall pay to the Company or the Employer in cash any amount of Tax-Related Items that the Company or the Employer may be

required to withhold as a result of Participant’s participation in this Sub-Plan or with respect to the shares that cannot be satisfied,

or which the Company determines should not be satisfied, by one or more of the means acceptable to the Company in its sole and absolute

discretion previously described.

The

Company may refuse to deliver shares or proceeds from the sale of shares if Participant fails to comply with his or her obligations in

connection with the Tax-Related Items.

16. Tax

Consequences. PARTICIPANT UNDERSTANDS THAT PARTICIPANT MAY SUFFER ADVERSE TAX CONSEQUENCES AS A RESULT OF THE GRANT, VESTING

OR SETTLEMENT OF THE AWARD OR DELIVERY OR DISPOSITION OF THE SHARES. PARTICIPANT REPRESENTS THAT (a) PARTICIPANT HAS CONSULTED WITH ANY

TAX ADVISER THAT PARTICIPANT DEEMS ADVISABLE IN CONNECTION WITH THE GRANT, VESTING, DELIVERY OR SETTLEMENT OF THE AWARD OR DISPOSITION

OF THE SHARES, (b) THE COMPANY IS NOT PROVIDING ANY TAX, LEGAL OR FINANCIAL ADVICE, NOR IS THE COMPANY MAKING ANY RECOMMENDATIONS REGARDING

PARTICIPANT’S PARTICIPATION IN THIS SUB-PLAN, OR PARTICIPANT’S ACQUISITION OR SALE OF THE SHARES, AND (c) PARTICIPANT IS

NOT RELYING ON THE COMPANY FOR ANY TAX ADVICE. If Participant is or becomes a U.S. taxpayer or employment (or services) is provided in

the United States: Participant hereby acknowledges that Participant has been informed that, with respect to unvested Awards, there will

be a recognition of taxable income to Participant, measured by the excess, if any, of the Fair Market Value of the unvested shares, at

the time they are delivered, over the purchase price for such shares (if any).

17. Rights

as a Stockholder. Except as otherwise provided by the Committee, no Participant shall have any rights as a stockholder of

the Company in respect of any Award prior to its vesting; provided that the Participant shall have the right to receive accumulated

dividends on terms and conditions specified by the Committee or distributions with respect to the corresponding number of Shares

underlying each PRSU at the settlement thereof, unless such PRSU is converted into deferred stock units in accordance with an

election made in accordance with Section 7(f), in which case such accumulated dividends or distributions shall be paid by the

Company to the Participant at such time as the deferred stock units are converted into shares.

18. Clawback.

(a) Compensation

Recoupment Policy. In the event that any of the Awards are at any time affected by an Accounting Restatement and the Company has

a clawback or compensation recoupment policy, whether or not adopted in compliance with SEC Rule 10D-1, as amended, and whether on a

stand-alone basis or combined with other policies, each Participant hereby acknowledges and agrees that Participant and the Award, including

any shares that may be delivered to the Participant pursuant to an Award, will be subject to such clawback or compensation recoupment

policy. The terms and conditions of any such compensation recoupment policy will be deemed incorporated by reference into this Sub-Plan.

For purposes hereof, “Accounting Restatement” means the accounting restatement of any of the Company’s financial

statements filed with the Securities and Exchange Commission under the Exchange Act or the Securities Act, due to the Company’s

material noncompliance with any financial reporting requirement under the securities laws, including any required accounting restatement

to correct an error in previously issued financial statements that is material to the previously issued financial statements, or that

would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period.

(b) Participant

Contribution to Restatement. Without limiting Section 18(a), if the Company and its Subsidiaries terminate the Participant’s

service relationship due to the Participant’s gross negligence or willful misconduct (whether or not such actions also constitute

Cause hereunder) which conduct, directly or indirectly, results in the Company preparing an Accounting Restatement, any Award granted

or PRSUs allocated hereunder, whether or not vested (and any gains thereon), shall be subject to forfeiture, recovery and “clawback.”

In addition, the Participant acknowledges and agrees that any Award granted or PRSUs allocated hereunder (whether or not vested) may

be subject to forfeiture, recovery and “clawback” to the extent required pursuant to the terms and conditions of any Company

Agreement.

19. Listing,

Registration and Qualification. If the Committee determines that the listing, registration or qualification upon any Trading

Market or under any law of Shares subject to any Award is necessary or desirable as a condition of, or in connection with, the granting

of same or the issue or purchase of Shares thereunder, no such Award may be paid out, and no Shares may be issued, unless such listing,

registration or qualification is effected free of any conditions not acceptable to the Committee.

20. Tax

Provisions.

(a) Section

409A Compliance. All Awards and PRSUs granted under this Sub-Plan are intended either not to be subject to Section 409A of the Code

under the short-term deferral exemption regulations or, if subject to Section 409A of the Code, to be administered, operated and construed

in compliance with Section 409A of the Code. Notwithstanding this or any other provision of this Sub-Plan or any PRSU award agreement

to the contrary, the Committee may amend this Sub-Plan or any award agreement granted hereunder in any manner or take any other action

that it determines, in its sole discretion, is necessary, appropriate or advisable (including replacing any Award or PRSU) to cause this

Sub-Plan or any Award granted hereunder to comply with Section 409A of the Code and all regulations and other guidance issued thereunder

or to not be subject to Section 409A of the Code. Notwithstanding anything to the contrary contained herein, the Company shall not be

responsible for, or required to reimburse or otherwise make any Participant whole for, any tax imposed on any Participant pursuant to

Section 409A of the Code in respect of any grant under this Sub-Plan. Notwithstanding other provisions of this Sub-Plan or any award

agreements hereunder, unless otherwise determined by the Committee in its sole and absolute discretion, no Award shall be granted, deferred,

accelerated, extended, paid out or modified under this Sub-Plan in a manner that would result in the imposition of an additional tax

under Section 409A of the Code upon a Participant. In the event that it is reasonably determined by the Committee that, as a result of

Section 409A of the Code, payments in respect of any Award under this Sub-Plan may not be made at the time contemplated by the terms

of this Sub-Plan or the relevant award agreement, as the case may be, without causing the Participant holding such Award to be subject

to taxation under Section 409A of the Code, including as a result of the fact that the Participant is a “specified employee”

under Section 409A of the Code, the Company will make such payment on the first day that would not result in the Participant incurring

any tax liability under Section 409A of the Code.

(b) Compliance

with Code Section 162(m). The terms of this Sub-Plan, including the definitions of Covered Employee and other terms used therein,

shall be interpreted in a manner consistent with Code Section 162(m) and regulations thereunder. The foregoing notwithstanding, because

the Committee cannot determine with certainty whether a given Participant will be a Covered Employee with respect to a fiscal year that

has not yet been completed, the term Covered Employee as used herein shall mean only a person designated by the Committee as likely to

be a Covered Employee with respect to a specified fiscal year. If any provision of this Sub-Plan or any Award document relating to a

performance award that is designated as intended to comply with Code Section 162(m) does not comply or is inconsistent with the requirements

of Code Section 162(m) or regulations thereunder, such provision shall be construed or deemed amended to the extent necessary to conform

to such requirements, and no provision shall be deemed to confer upon the Committee or any other person discretion to increase the amount

of compensation otherwise payable in connection with any such Award upon attainment of the applicable performance objectives.

21. Nonexclusivity

of this Sub-Plan. Neither the adoption of this Sub-Plan by the Board nor its submission to the shareholders of the Company for

approval shall be construed as creating any limitations on the power of the Board or a committee thereof to adopt such other incentive

arrangements, apart from this Sub-Plan, as it may deem desirable.

22. Amendment

and Termination

(a) Amendment.

The Board of Directors or the Committee, without approval of the stockholders, may amend or terminate this Sub-Plan, except that no amendment

shall become effective without prior approval of the stockholders of the Company if stockholder approval would be required by applicable

law or regulations or by any listing or quotation requirement of the Trading Market.

(b) Savings

Amendments. Notwithstanding any other provisions of this Sub-Plan, and in addition to the powers of amendment set forth in this Section

22 and Section 20 or otherwise, the provisions hereof and the provisions of any Award made hereunder may be amended unilaterally by the

Committee from time to time to the extent necessary (and only to the extent necessary) to prevent the implementation, application or

existence (as the case may be) of any such provision from (i) requiring the inclusion of any compensation deferred pursuant to the provisions

of this Sub-Plan (or an Award thereunder) in a Participant’s gross income pursuant to Section 409A of the Code, and the regulations

issued thereunder from time to time, (ii) limiting the tax deductibility of any payment in settlement of an Award under Section 162(m)

of the Code, (iii) inadvertently causing any Award hereunder to be treated as providing for the deferral of compensation pursuant to

such Code section and regulations, and/or (iv) failing to comply with applicable law. No amendment or modification shall materially and

adversely affect a Participant’s vested rights without the Participant’s written consent, except as required to comply with

applicable law (including Code Sections 409A and 162(m)).

The Committee may terminate this Sub-Plan at any time. From time to time, the Committee may suspend this Sub-Plan, in whole or in part.

From time to time, the Committee may amend this Sub-Plan or PRSU award agreement, including the adoption of amendments deemed necessary

or desirable to correct any defect or supply an omission or reconcile any inconsistency in this Sub- Plan or in any Award or PRSU award

agreement granted hereunder so long as stockholder approval has been obtained if required. No amendment, termination or modification

of this Sub- Plan, Award or PRSU award agreement may in any manner affect Awards or PRSUs heretofore granted without the consent of the

Participant unless the Committee has made a determination that an amendment or modification is in the best interest of all persons to

whom Awards or PRSUs have heretofore been granted, but in no event may such amendment or modification result in an increase in the amount

of compensation payable pursuant to such Award or PRSU.

23. Substitution

of Awards under this Sub-Plan. The Committee may, in its discretion, permit holders of Awards under this Sub-Plan to surrender

outstanding Awards in order to exercise or realize rights under other awards, or in exchange for the grant of new awards, or require

holders of awards to surrender outstanding awards as a condition precedent to the grant of new awards under this Sub-Plan, but only if

such surrender, exercise, realization, exchange, or grant (a) would not constitute a distribution of deferred compensation for purposes

of Section 409A(a)(3) of the Code or (b) constitutes a distribution of deferred compensation that is permitted under regulations issued

pursuant to Section 409A(a)(3) of the Code.

24. Limitation

of Liability; Indemnification. To the fullest extent permitted by the act, no manager, administrator nor any person acting pursuant

to authority delegated by a manager or the administrator shall be personally liable, responsible or accountable, in damages or otherwise,

to the Company or any Participant for any action or determination under this Sub-Plan unless such person acted in bad faith with respect

to such action or determination, and shall to the extent permitted by law be fully indemnified and protected by the Company with respect

to any such action or determination. Accordingly, each Participant agrees that in acting in accordance with the terms of, and exercising

such authority, the officers, directors and any person acting pursuant to authority delegated by the Board or Committee shall be subject

to no express or implied fiduciary duty but only to the implied covenant of good faith and fair dealing.

25. Expiration,

etc. Under this Sub-Plan, EPUs may be awarded from time to time prior to the expiration of ten (10) years from the date of adoption

of this Sub-Plan, at which time this Sub-Plan will expire. Such expiration will not terminate then outstanding, previously awarded EPUs

or their rights hereunder. This Sub-Plan may be extended, terminated or modified by the administrator at any time prior to the expiration

of ten (10) years from the date of adoption of this Sub-Plan.

26. Not

a Contract of Employment, etc. Nothing in this Sub-Plan or in any grant thereunder shall confer any right on a Participant to

continue in the service or employ as a director or officer of or in the performance of services for the Company or a Subsidiary or shall

interfere in any way with the right of the Company or a Subsidiary to terminate the employment or performance of services or to reduce

the compensation or responsibilities of a Participant at any time. By accepting any Award under this Sub-Plan, each Participant and each

person claiming under or through him or her shall be conclusively deemed to have indicated his or her acceptance and ratification of,

and consent to, any action taken under this Sub-Plan by the Company, the Board or the Committee.

27. Right

of Setoff. The Company or any Subsidiary or affiliate may, to the extent permitted by applicable law and to the extent consistent

with the requirements of or exemption from Section 409A of the Code, deduct from and set off against any amounts the Company or any Subsidiary

or affiliate may owe to a Participant from time to time, including amounts payable in connection with any Award, owed as wages, fringe

benefits, or other compensation owed to such Participant, such amounts as may be owed by such Participant to the Company, although Participant

shall remain liable for any part of each Participant’s payment obligation not satisfied through such deduction and setoff. By accepting

any Award granted hereunder, each Participant agrees to any deduction or setoff under this Section 27.

28. No

Trust Fund Created. Neither the Company nor any of its direct or indirect Subsidiaries, or any of their respective Affiliates,

shall set aside any money in trust or otherwise to guarantee payments of any amounts due under this Sub-Plan. Only the Company (and no

other person or entity) will be responsible for payment, will make payment, if and when due, out of its general funds.

29. Employment

Status; Claims to Awards. Nothing in this Sub-Plan shall be construed to limit in any way the right of the Company or any Subsidiary

to terminate the employment of any person at any time. The Awards and PRSUs represent unfunded and unsecured obligations of the Company

and Participant in respect of this Sub- Plan shall have no rights other than those of a general unsecured creditor to the Company.

30. Severability.

Whenever possible, each provision of this Sub-Plan shall be interpreted in such manner as to be effective and valid under applicable

law, but if any provision of this Sub-Plan is held to be prohibited by or invalid under applicable law, such provision shall be ineffective

only to the extent of such prohibition or invalidity, without invalidating the remainder of this Sub-Plan.

31. Governing

provisions that might otherwise refer construction or interpretation of this Sub-Plan to the substantive law of another jurisdiction.

General. Subject to the provisions of paragraph 3.2 below, if a Grantee’s service with the Company terminates for any

other respects.

laws or regulations.

takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related items related to

Grantee’s participation in the Sub-Plan and legally applicable to Grantee (“Tax-Related Items”), Grantee acknowledges

that the ultimate liability for all Tax-Related Items is and remains Grantee’s responsibility and may exceed the amount actually

withheld by the Company or the Employer. Grantee further acknowledges that the Company and/or the Employer (i) make no representations

or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Units, including the grant of the

Units, the vesting of Units, the conversion of the Units into Shares or the receipt of an equivalent cash payment, the subsequent sale

of any Shares acquired at vesting and the receipt of any dividends and/or dividend equivalents; and (ii) do not commit to and are under

no obligation to structure the terms of the grant or any aspect of the Units to reduce or eliminate Grantee’s liability for Tax-Related

Date and the date of any relevant taxable event, Grantee acknowledges that the Company and/or the Employer (or former employer, as applicable)

may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

4

Prior

to any relevant taxable or tax withholding event, as applicable, Grantee shall pay, or make adequate arrangements satisfactory to the

Company and/or the Employer to satisfy all Tax-Related Items. In this regard, pursuant to Section 15 of the Sub-Plan, if permissible

under local law and unless otherwise provided by the Committee prior to the vesting of the shares, Grantee authorizes the Company or

the Employer, or their respective agents, to withhold all applicable Tax-Related Items in Shares to be issued upon vesting/settlement

of the Units. Alternatively, or in addition, Grantee authorizes the Company and/or the Employer, or their respective agents, at the Company’s

discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following: (i) provided that

at the time of payment the shares of Common Stock of the Company are publicly traded, pursuant to a program developed under Regulation

T as promulgated by the Federal Reserve Board known as a “broker-assisted exercise”, “same day sale”, or “sell

to cover;” (ii) withholding from Grantee’s wages or other cash compensation paid to Grantee by the Company and/or the Employer;

(iii) withholding from proceeds of the sale of Shares acquired upon vesting/settlement of the Units either through a voluntary sale or

through a mandatory sale arranged by the Company (on Grantee’s behalf pursuant to this authorization); or (iv) personal check or

other cash equivalent acceptable to the Company, all as more particularly described in the Sub-Plan.

The

Company may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding amounts or other applicable

withholding rates. If the obligation for Tax-Related Items is satisfied by withholding a number of Shares as described herein, for tax

purposes, Grantee shall be deemed to have been issued the full number of Shares subject to the Award, notwithstanding that a number of

the Shares are held back solely for the purpose of paying the Tax-Related Items due as a result of Grantee’s participation in the

Plan.

Finally,

Grantee shall pay to the Company or to the Employer any amount of Tax-Related Items that the Company or the Employer may be required

to withhold or account for as a result of Grantee’s participation in the Plan that cannot be satisfied by the means previously

described. The Company may refuse to issue or deliver shares or the proceeds of the sale of Shares if Grantee fails to comply with his

or her obligation in connection with the Tax-Related Items.

14.

Amendments. Unless otherwise provided in the Sub-Plan or this Award Agreement, this Award Agreement may be amended only by

a written agreement executed by the Company and Grantee.

15.

Integrated Agreement. This Award Agreement, the Sub-Plan and the 2020 Plan shall constitute the entire understanding and agreement

of Grantee and the Company with respect to the subject matter contained herein or therein and supersedes any prior agreements, understandings,

restrictions, representations, or warranties between Grantee and the Company with respect to such subject matter other than those as

set forth or provided for herein or therein. To the extent contemplated herein or therein, the provisions of this Award Agreement shall

survive any settlement of the Award and shall remain in full force and effect.

16.

Severability. If one or more of the provisions of this Award Agreement shall be held invalid, illegal or unenforceable in

any respect, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby

and the invalid, illegal or unenforceable provisions shall be deemed null and void; however, to the extent permissible by law, any provisions

which could be deemed null and void shall first be construed, interpreted or revised retroactively to permit this Award Agreement to

be construed so as to foster the intent of this Award Agreement and the Sun-Plan.

17.

Counterparts. This Award Agreement may be executed in counterparts, each of which shall be deemed an original, but all of

which together shall constitute one and the same instrument.

18.

Governing Law and Venue. This Award Agreement shall be interpreted and administered under the laws of the State of Delaware.

5

For

purposes of litigating any dispute that arises under this grant or this Award Agreement, the parties hereby submit to and consent to

the jurisdiction of the State of New York, agree that such litigation shall be conducted in the courts located in Manhattan, New York

City, or the federal courts for the United States for the Southern District of New York, where this grant is made and/or to be performed.

19.

Other. Grantee represents that Grantee has read and is familiar with the provisions of the 2020 Plan, the Sub-Plan and this

Award Agreement, and hereby accepts the Award subject to all of their terms and conditions.

20.

Section 409A Compliance. Section 409A of the Code imposes an additional 20% tax, plus interest, on payments from “non-qualified

deferred compensation plans.” Certain payments under this Award Agreement could be considered to be payments under a “non-qualified

deferred compensation plan.” The additional 20% tax and interest do not apply if the payment qualifies for an exception to the

requirements of Section 409A or complies with the requirements of Section 409A. The Company believes, but does not and cannot warrant

or guaranty, that the payments due pursuant to this Award Agreement qualify for the short-term deferral exception to Section 409A as

set forth in Treasury Regulation Section 1.409A-1(b)(4). Notwithstanding anything to the contrary in this Award Agreement, if the Company

determines that neither the short-term deferral exception nor any other exception to Section 409A applies to the payments due pursuant

to this Award Agreement, to the extent any payments are due on Grantee’s termination of employment, the term “termination

of employment” shall mean “separation from service” as defined in Treasury Regulation Section 1.409A-1(h). In addition,

if Grantee is a “specified employee” (as defined in Treasury Regulation Section 1.409A-1(i)) and any payments due pursuant

to this Award Agreement are payable on Grantee’s “separation from service,” then such payments shall be paid on the

first business day following the expiration of the six month period following Grantee’s “separation from service.”

This Award Agreement shall be operated in compliance with Section 409A or an exception thereto and each provision of this Award Agreement

shall be interpreted, to the extent possible, to comply with Section 409A or to qualify for an applicable exception. Grantee remains

solely responsible for any adverse tax consequences imposed upon Grantee by Section 409A.

21.

Imposition of Other Requirements. The Company reserves the right to impose other requirements on Grantee’s participation

in the Sub-Plan, on the Units and on any Shares acquired under the Sub-Plan, to the extent the Company determines it is necessary or

advisable in order to comply with applicable law or facilitate the administration of the Sub-Plan, and to require Grantee to sign any

additional agreements or undertakings that may be necessary to accomplish the foregoing.

IN

WITNESS WHEREOF, the Company has caused this Award Agreement to be signed by its duly authorized representative and Grantee has signed

this Award Agreement as of the date first written above.
