conditions include, but are not limited to, the exercise price, the time or times when Awards may be exercised (which may be based

(c)Effect
of Administrator’s Decision. The Administrator’s decisions, determinations and interpretations will be final and
binding on all Participants.

 

5.Eligibility.
Awards may be granted to Service Providers.

 

6.Options.

 

(a)Grant
of Options. Subject to the terms and provisions of the Plan, the Administrator, at any time and from time to time, may grant
Options in such amounts as the Administrator, in its sole discretion, will determine.

 

(b)Award
Agreement. Each Award of an Option will be evidenced by an Award Agreement that will specify the exercise price, the term
of the Option, the number of Units subject to the Option, the exercise restrictions, if any, applicable to the Option, and such
other terms and conditions as the Administrator, in its sole discretion, will determine.

 

    	 	 -4-	 

    	 

    

 

(c)Term
of Option. The term of each Option will be stated in the Award Agreement; provided, however, that the term will
be no more than ten (10) years from the date of grant thereof.

 

(d)Exercise
Price and Consideration.

 

(i)Exercise
Price. The per Unit exercise price for the Units to be issued pursuant to the exercise of an Option will be determined by
the Administrator, but will be no less than one hundred percent (100%) of the Fair Market Value per Unit on the date of grant.
Notwithstanding the foregoing provisions of this Section 6(d)(i), Options may be granted with a per Unit exercise price of less
than one hundred percent (100%) of the Fair Market Value per Unit on the date of grant pursuant to a transaction described in,
and in a manner consistent with, Code Section 424(a).

 

(ii)Form
of Consideration. The Administrator will determine the acceptable form of consideration for exercising an Option, including
the method of payment. Such consideration may consist entirely of: (1) cash; (2) check; (3) other Units, provided that
such Units have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Units as to which such
Option will be exercised and provided further that accepting such Units will not result in any adverse accounting consequences
to the Company, as the Administrator determines in its sole discretion; (4) consideration received by the Company under a cashless
exercise program (whether through a broker or otherwise) implemented by the Company in connection with the Plan; (5) such other
consideration and method of payment for the issuance of Units to the extent permitted by Applicable Laws; or (6) any combination
of the foregoing methods of payment. In making its determination as to the type of consideration to accept, the Administrator
will consider if acceptance of such consideration may be reasonably expected to benefit the Company.

 

(e)Exercise
of Options.

 

(i)Procedure
for Exercise; Rights as a Member. Any Option granted hereunder will be exercisable according to the terms of the Plan and
at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may
not be exercised for a fraction of a Unit. An Option will be deemed exercised when the Company receives: (i) notice of exercise
(in such form as the Administrator may specify from time to time) from the person entitled to exercise the Option, and (ii) full
payment for the Units with respect to which the Option is exercised (together with applicable tax withholding). Full payment may
consist of any consideration and method of payment authorized by the Administrator and permitted by the Award Agreement and the
Plan. Units issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the Participant,
in the name of the Participant and his or her spouse. Until the Units are issued (as evidenced by the appropriate entry on the
books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive distributions or allocations
of profits or losses or other rights as a Member shall exist with respect to the Units subject to the Option, notwithstanding
the exercise of the Option. The Company will issue (or cause to be issued) such Units promptly after the Option is exercised.
No adjustment will be made for a dividend or other right for which the record date is prior to the date the Units are issued,
except as provided in Section 13 of the Plan. Exercising an Option in any manner will decrease the number of Units thereafter
available, both for purposes of the Plan and for sale under the Option, by the number of Units as to which the Option is exercised.

 

    	 	 -5-	 

    	 

    

 

(ii)Termination
of Relationship as a Service Provider. If a Participant ceases to be a Service Provider, other than upon the Participant’s
termination as the result of the Participant’s death or Disability, the Participant may exercise his or her Option within
thirty (30) days of termination, or such longer period of time as is specified in the Award Agreement (but in no event later than
the expiration of the term of such Option as set forth in the Award Agreement) to the extent that the Option is (1) exercisable
on such date pursuant to any exercise restrictions set forth in the Award Agreement and (2) vested on the date of termination.
Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire
Option, the Units covered by the unvested portion of the Option will revert to the Plan. If after termination the Participant
does not exercise his or her Option within the time specified by the Administrator, the Option will terminate, and the Units covered
by such Option will revert to the Plan.

 

(iii)Disability
of Participant. If a Participant ceases to be a Service Provider as a result of the Participant’s Disability, the Participant
may exercise his or her Option within six (6) months of termination, or within such longer period of time as is specified in the
Award Agreement (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement) to
the extent the Option is (1) exercisable on such date pursuant to any exercise restrictions set forth in the Award Agreement and
(2) vested on the date of termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant
is not vested as to his or her entire Option, the Units covered by the unvested portion of the Option will revert to the Plan.
If after termination the Participant does not exercise his or her Option within the time specified herein, the Option will terminate,
and the Units covered by such Option will revert to the Plan.

 

(iv)Death
of Participant. If a Participant dies while a Service Provider, the Option may be exercised within six (6) months following
the Participant’s death, or within such longer period of time as is specified in the Award Agreement (but in no event later
than the expiration of the term of such Option as set forth in the Award Agreement) to the extent that the Option is (1) exercisable
on such date pursuant to any exercise restrictions set forth in the Award Agreement and (2) vested on the date of death, by the
Participant’s designated beneficiary, provided that such beneficiary has been designated prior to the Participant’s
death in a form acceptable to the Administrator. If no such beneficiary has been designated by the Participant, then such Option
may be exercised by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred
pursuant to the Participant’s will or in accordance with the laws of descent and distribution. Unless otherwise provided
by the Administrator, if at the time of death Participant is not vested as to his or her entire Option, the Units covered by the
unvested portion of the Option will immediately revert to the Plan. If the Option is not so exercised within the time specified
herein, the Option will terminate, and the Units covered by such Option will revert to the Plan.

 

7.Profits
Interests.

 

(a)Award
Agreement. Subject to the terms and conditions of the Plan and the LLC Agreement, the Administrator may grant Profits Interests
at any time and from time to time, as determined by the Administrator, in its sole discretion. Each Profits Interest grant will
be evidenced by an Award Agreement that will specify the number of Units that are being granted as Profits Interests, the Profits
Interest Threshold Amount, Period of Restriction and the vesting schedule, if any, applicable to the Profits Interest grant, and
such other terms and conditions as the Administrator, in its sole discretion, will determine.

 

(b)Forfeiture.
If a Participant’s status as a Service Provider is terminated for any reason by the Participant or the Company before the
Profits Interests have vested, unless otherwise determined by the Administrator or unless otherwise provided in the Award Agreement,
the Participant will forfeit all non-vested Profits Interests to the Company for no consideration without further action by the
Company.

 

    	 	 -6-	 

    	 

    

 

(c)Rights
as a Member. Each Participant granted a Profits Interest Award shall agree to be bound by and comply with the terms of the
LLC Agreement.

 

(d)Payment.
Unless otherwise determined by the Administrator, no amount shall be paid to the Company for the grant of Profits Interests.

 

8.Restricted
Units.

 

(a)Grant
of Restricted Units. Subject to the terms and provisions of the Plan, the Administrator, at any time and from time to time,
may grant Restricted Units to Service Providers in such amounts as the Administrator, in its sole discretion, will determine.

 

(b)Restricted
Unit Award Agreement. Each Award of Restricted Units will be evidenced by an Award Agreement that will specify the Period
of Restriction, the number of Restricted Units granted, and such other terms and conditions as the Administrator, in its sole
discretion, will determine. Unless the Administrator determines otherwise, if the Units are certificated, the Company as escrow
agent will hold Restricted Units until the restrictions on such Restricted Units have lapsed.

 

(c)Transferability.
Except as provided in this Section 8 or as the Administrator determines, Restricted Units may not be sold, transferred, pledged,
assigned, or otherwise alienated or hypothecated until the end of the applicable Period of Restriction.

 

(d)Other
Restrictions. The Administrator, in its sole discretion, may impose such other restrictions on Restricted Units as it may
deem advisable or appropriate.

 

(e)Removal
of Restrictions. Except as otherwise provided in this Section 8, Restricted Units granted under the Plan will be released
from escrow (if such Units are certificated) as soon as practicable after the last day of the Period of Restriction or at such
other time as the Administrator may determine. The Administrator, in its discretion, may accelerate the time at which any restrictions
will lapse or be removed.

 

(f)Return
of Restricted Units to Company. On the date set forth in the Award Agreement, the Restricted Units for which restrictions
have not lapsed will revert to the Company and again will become available for grant under the Plan.

 

9.Compliance
With Code Section 409A. Awards will be designed and operated in such a manner that they are either exempt from the application
of, or comply with, the requirements of Code Section 409A, except as otherwise determined in the sole discretion of the Administrator.
The Plan and each Award Agreement under the Plan is intended to meet the requirements of Code Section 409A and will be construed
and interpreted in accordance with such intent, except as otherwise determined in the sole discretion of the Administrator. To
the extent that an Award or payment, or the settlement or deferral thereof, is subject to Code Section 409A, the Award will be
granted, paid, settled or deferred in a manner that will meet the requirements of Code Section 409A, such that the grant, payment,
settlement or deferral will not be subject to the additional tax or interest applicable under Code Section 409A.

 

10.Leaves
of Absence/Transfer Between Locations. Unless the Administrator provides otherwise, vesting of Awards granted hereunder will
be suspended during any unpaid leave of absence. A Participant will not cease to be a Service Provider in the case of (i) any
leave of absence approved by the Company or (ii) transfers between locations of the Company. No such leave may exceed three (3)
months, unless reemployment upon expiration of such leave is guaranteed by statute or contract.

 

    	 	 -7-	 

    	 

    

 

11.Limited
Transferability of Awards. Unless determined otherwise by the Administrator, Awards may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of descent and distribution, and may be exercised,
during the lifetime of the Participant, only by the Participant. If the Administrator in its sole discretion makes an Award transferable,
such Award may only be transferred (i) by will, (ii) by the laws of descent and distribution, or (iii) as permitted by Rule 701
of the Securities Act.

 

12.Conversion.
Subject to the provisions of the merger, reorganization or other agreement setting forth the terms of a direct exchange, merger
or other reorganization transaction, upon a Conversion, all Awards granted under the Plan shall be exchanged for or converted
into, in such transaction, options to acquire shares of the resulting corporation’s common stock or the resulting corporation’s
restricted common stock, in either case, with terms substantially equivalent to the terms of the Awards they are intended to replace.

 

13.Adjustments;
Dissolution or Liquidation; Merger or Change of Control Event.

 

(a)Adjustments.
In the event that any dividend or other distribution (whether in the form of cash, Units, other securities, or other property),
recapitalization, split, reverse split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or
exchange of Units or other securities of the Company, or other change in the corporate structure of the Company affecting the
Units occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended
to be made available under the Plan, will adjust the number and class of Units that may be delivered under the Plan and/or the
number, class, and price of Units covered by each outstanding Award; provided, however, that the Administrator will
make such adjustments to an Award required by Section 25102(o) of the California Corporations Code to the extent the Company is
relying upon the exemption afforded thereby with respect to the Award.

 

(b)Dissolution
or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator will notify each
Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously
exercised, an Award will terminate immediately prior to the consummation of such proposed action.

 

(c)Merger
or Change of Control Event. In the event of a merger or Change of Control Event, each outstanding Award shall be treated as
the Administrator determines, without a Participant’s consent, including, without limitation, that (i) Awards will be assumed,
or substantially equivalent Awards will be substituted, by the acquiring or succeeding entity (or an affiliate thereof) with appropriate
adjustments as to the number and kind of shares and prices; (ii) upon written notice to a Participant, a participant’s Awards
will terminate upon or immediately prior to the consummation of such merger or Change of Control Event; (iii) outstanding Awards
will vest and become exercisable, realizable, or payable, or restrictions applicable to an Award will lapse, in whole or in part
prior to or upon consummation of such merger or Change of Control Event, and, to the extent the Administrator determines, terminate
upon or immediately prior to the effectiveness of such transaction; (iv) (A) the termination of an Award in exchange for an amount
of cash and/or property, if any, equal to the amount that would have been attained upon the exercise of such Award or realization
of the Participant’s rights as of the date of the occurrence of the transaction (and, for the avoidance of doubt, if as
of the date of the occurrence of the transaction the Administrator determines in good faith that no amount would have been attained
upon the exercise of such Award or realization of the Participant’s rights, then such Award may be terminated by the Company
without payment), or (B) the replacement of such Award with other rights or property selected by the Administrator in its sole
discretion; or (v) any combination of the foregoing. In taking any of the actions permitted under this subsection 13(c), the Administrator
will not be obligated to treat all Awards or all Awards held by a Participant similarly.

 

    	 	 -8-	 

    	 

    

 

For
the purposes of this paragraph, an Award will be considered assumed if, following the merger or Change of Control Event, the Award
confers the right to purchase, for each Unit subject to the Award immediately prior to the merger or Change of Control Event,
the consideration (whether stock, cash, or other securities or property) received in the transaction by holders of Units for each
Unit held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration
chosen by the holders of a majority of the outstanding Units); provided, however, that if such consideration received
in the merger or Change of Control Event was not solely common stock of the successor corporation or its parent corporation, the
Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise
of an Option for each Unit subject to the Option to be solely common stock of the successor corporation or its parent corporation
equal in fair market value to the per Unit consideration received by holders of Units in the merger or Change of Control Event.

 

14.Tax
Withholding.

 

(a)Withholding
Requirements. Prior to the delivery of any Units or cash pursuant to an Award (or exercise thereof), the Company will have
the power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy
federal, state, local, foreign or other taxes (including the Participant’s FICA obligation) required to be withheld with
respect to such Award (or exercise thereof).

 

(b)Withholding
Arrangements. The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to time,
may permit a Participant to satisfy such tax withholding obligation, in whole or in part by (without limitation) (i) paying cash,
(ii) electing to have the Company withhold otherwise deliverable Units having a Fair Market Value equal to the minimum statutory
amount required to be withheld, (iii) delivering to the Company already-owned Units having a Fair Market Value equal to the statutory
amount required to be withheld, provided that the delivery of such Units will not result in any adverse accounting consequences,
as the Administrator determines in its sole discretion, or (iv) selling a sufficient number of Units otherwise deliverable to
the Participant through such means as the Administrator may determine in its sole discretion (whether through a broker or otherwise)
equal to the amount required to be withheld. The amount of the withholding requirement will be deemed to include any amount which
the Administrator agrees may be withheld at the time the election is made, not to exceed the amount determined by using the maximum
federal, state or local marginal income tax rates applicable to the Participant with respect to the Award on the date that the
amount of tax to be withheld is to be determined. The Fair Market Value of the Units to be withheld or delivered will be determined
as of the date that the taxes are required to be withheld.

 

15.No
Effect on Employment or Service. Neither the Plan nor any Award will confer upon a Participant any right with respect to continuing
the Participant’s relationship as a Service Provider with the Company, nor will they interfere in any way with the Participant’s
right or the Company’s right to terminate such relationship at any time, with or without cause, to the extent permitted
by Applicable Laws.

 

16.Date
of Grant. The date of grant of an Award will be, for all purposes, the date on which the Administrator makes the determination
granting such Award, or such other later date as is determined by the Administrator. Notice of the determination will be provided
to each Participant within a reasonable time after the date of such grant.

 

17.Term
of Plan. Subject to Section 21 of the Plan, the Plan will become effective upon its adoption by the Board. Unless sooner terminated
under Section 18, it will continue in effect for a term of ten (10) years from the later of (a) the effective date of the Plan,
or (b) the earlier of the most recent Board or Member approval of an increase in the number of Units reserved for issuance under
the Plan.

 

    	 	 -9-	 

    	 

    

 

18.Amendment
and Termination of the Plan.

 

(a)Amendment
and Termination. The Board may at any time amend, alter, suspend or terminate the Plan.

 

(b)Member
Approval. The Company will obtain Member approval of any Plan amendment to the extent necessary and desirable to comply with
Applicable Laws.

 

(c)Effect
of Amendment or Termination. No amendment, alteration, suspension or termination of the Plan will impair the rights of any
Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing
and signed by the Participant and the Company. Termination of the Plan will not affect the Administrator’s ability to exercise
the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination.

 

19.Conditions
Upon Issuance of Units.

 

(a)Legal
Compliance. Units will not be issued pursuant to the exercise of an Award unless the exercise of such Award and the issuance
and delivery of such Units will comply with Applicable Laws and will be further subject to the approval of counsel for the Company
with respect to such compliance.

 

(b)Investment
Representations. As a condition to the exercise of an Award, the Company may require the person exercising such Award to represent
and warrant at the time of any such exercise that the Units are being purchased only for investment and without any present intention
to sell or distribute such Units if, in the opinion of counsel for the Company, such a representation is required.

 

20.Inability
to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Units hereunder, will
relieve the Company of any liability in respect of the failure to issue or sell such Units as to which such requisite authority
will not have been obtained.

 

21.Member
Approval. The Plan will be subject to approval by the Members of the Company within twelve (12) months after the date the
Plan is adopted by the Board. Such Member approval will be obtained in the manner and to the degree required under Applicable
Laws.

II.
AGREEMENT

 

1.
Grant of Option. The Administrator of the Company hereby grants to the Optionee named in the Notice of Unit Option Agreement
(the “Optionee”), an option (the “Option”) to purchase the number of Units
set forth in the Notice of Unit Option Agreement, at the exercise price per Unit set forth in the Notice of Unit Option Grant
(the “Exercise Price”), and subject to the terms and conditions of the Plan, which is incorporated herein
by reference. Subject to Section 18(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and
this Option Agreement, the terms and conditions of the Plan shall prevail.

 

This
Option is not intended to qualify as an Incentive Stock Option as defined in Section 422 of the Code. Instead, this Option is
a Nonstatutory Unit Option.

 

2.
Exercise of Option.

 

(a)
Right to Exercise. This Option shall be exercisable during its term in accordance with the Vesting Schedule set out in
the Notice of Unit Option Agreement and with the applicable provisions of the Plan and this Option Agreement.

 

(b)
Method of Exercise. This Option shall be exercisable by delivery of an exercise notice in the form attached as Exhibit
A (the “Exercise Notice”) or in a manner and pursuant to such procedures as the Administrator may
determine, which shall state the election to exercise the Option, the number of Units with respect to which the Option is being
exercised, and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied
by payment of the aggregate Exercise Price as to all exercised Units, together with any applicable tax withholding. This Option
shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate
Exercise Price, together with any applicable tax withholding.

 

No
Units shall be issued pursuant to the exercise of an Option unless such issuance and such exercise comply with Applicable Laws.
Assuming such compliance, for income tax purposes the Units shall be considered transferred to the Optionee on the date on which
the Option is exercised with respect to such Units.

 

3.
Optionee’s Representations. At the time this Option is exercised, the Optionee shall, if required by the Company,
concurrently with the exercise of all or any portion of this Option, deliver to the Company his or her Investment Representation
Statement in the form attached hereto as Exhibit B and execute the counterpart signature page to the LLC Agreement attached
hereto as Exhibit C.

 

4.
Lock-Up Period. Optionee hereby agrees that Optionee will not offer, pledge, sell, contract to sell, sell any option or
contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise
transfer or dispose of, directly or indirectly, any Unit (or other securities) of the Company or enter into any swap, hedging
or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Unit
(or other securities) of the Company held by Optionee (other than those included in the registration) for a period specified by
the representative of the underwriters of Units (or other securities) of the Company not to exceed 180 days following the effective
date of any registration statement of the Company filed under the Securities Act (or such other period as may be requested by
the Company or the underwriters to accommodate regulatory restrictions on (i) the publication or other distribution of research
reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule
2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto).

 

    	 -2-

     

    

 

Optionee
agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter which are
consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company
or the representative of the underwriters of Units (or other securities) of the Company, Optionee will provide, within ten (10)
days of such request, such information as may be required by the Company or such representative in connection with the completion
of any public offering of the Company’s securities pursuant to a registration statement filed under the Securities Act.
The obligations described in this Section 4 will not apply to a registration relating solely to employee benefit plans on Form
S-1 or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a Commission Rule
145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions
with respect to the Units (or other securities) subject to the foregoing restriction until the end of said 180 day (or other)
period. Optionee agrees that any transferee of the Option or Units acquired pursuant to the Option will be bound by this Section
4.

 

5.
Method of Payment. Payment of the aggregate Exercise Price shall be by either of the following, or a combination thereof,
at the election of the Optionee:

 

(a)
cash or check; or

 

(b)
if the Option is converted into an option covering shares of Company common stock, consideration received by the Company under
a formal cashless exercise program adopted by the Company in connection with the Plan.

 

6.
Restrictions on Exercise. This Option may not be exercised if the issuance of Units upon such exercise would constitute
a violation of any Applicable Law or the LLC Agreement.

 

7.
Non-Transferability of Option. This Option may not be transferred in any manner otherwise than by will or by the laws of
descent or distribution and may be exercised during the lifetime of Optionee only by Optionee. The terms of the Plan, the LLC
Agreement and this Option Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of the
Optionee.

 

8.
Term of Option. This Option may be exercised only within the term set out in the Notice of Unit Option Agreement, and may
be exercised during such term only in accordance with the Plan and the terms of this Option.

 

9.
Tax Obligations.

 

(a)
Tax Consequences. The Company makes no representations regarding the tax treatment related to the Option or its exercise.
THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE UNITS.

 

    	 -3-

     

    

 

(b)
Tax Withholding. Optionee agrees that Optionee may be subject to income and employment tax withholding by the Company on
the compensation income recognized by the Optionee and that the Company shall not be required to issue Units upon the exercise
of the Option unless Optionee adequately provides for the Company to satisfy its withholding obligations.

 

(c)
Code Section 409A. Under Code Section 409A, an Option that was granted with a per Unit exercise price that is determined
by the Internal Revenue Service (the “IRS”) to be less than the Fair Market Value of a Unit on the date
of grant (a “discount option”) may be considered “deferred compensation.” An Option that is a “discount
option” may result in (i) income recognition by Optionee prior to the exercise of the Option, (ii) an additional twenty
percent (20%) federal income tax, and (iii) potential penalty and interest charges. The “discount option” may also
result in additional state income, penalty and interest tax to the Optionee. Optionee acknowledges that the Company cannot and
has not guaranteed that the IRS will agree that the per Unit exercise price of this Option equals or exceeds the Fair Market Value
of a Unit on the date of grant in a later examination. Optionee agrees that if the IRS determines that the Option was granted
with a per Unit exercise price that was less than the Fair Market Value of a Unit on the date of grant, Optionee shall be solely
responsible for Optionee’s costs related to such a determination.

 

10.
Entire Agreement; Governing Law. The Plan and the LLC Agreement are incorporated herein by reference. The Plan, this Option
Agreement, and the LLC Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and
supersede in their entirety all prior undertakings and agreements of the Company and Optionee with respect to the subject matter
hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing signed by the Company
and Optionee. This Option Agreement is governed by the internal substantive laws but not the choice of law rules of Delaware.

 

11.
No Guarantee of Continued Service. OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF UNITS PURSUANT TO THE VESTING SCHEDULE
HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (OR THE SUBSIDIARY EMPLOYING OR RETAINING
OPTIONEE) AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING UNITS HEREUNDER. OPTIONEE FURTHER ACKNOWLEDGES
AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE
AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL,
AND SHALL NOT INTERFERE IN ANY WAY WITH OPTIONEE’S RIGHT OR THE COMPANY’S RIGHT (OR THE SUBSIDIARY EMPLOYING OR RETAINING
OPTIONEE) TO TERMINATE OPTIONEE’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

 

Optionee
acknowledges receipt of a copy of the Plan and the LLC Agreement and represents that he or she is familiar with the terms and
provisions thereof, and hereby accepts this Option subject to all of the terms and provisions thereof. Optionee has reviewed the
Plan, the LLC Agreement, and this Option in their entirety, has had an opportunity to obtain the advice of counsel prior to executing
this Option and fully understands all provisions of the Option. Optionee hereby agrees to accept as binding, conclusive and final
all decisions or interpretations of the Administrator upon any questions arising under the Plan, the LLC Agreement or this Option.
Optionee further agrees to notify the Company upon any change in the residence address indicated below.

NOTICE

 

OcuHub
LLC

9980
Huennekens Street

San
Diego, CA 92121

 

Attention:
President

 

1.
Exercise of Option. Effective as of today, ___________, _____, the undersigned (“Optionee”) hereby
elects to exercise Optionee’s option to purchase _________ Units (the “Units”) of OcuHub LLC (the
“Company”) under and pursuant to the 2015 Equity Incentive Plan (the “Plan”)
and the Unit Option Agreement dated ________,_______ (the “Option Agreement”).

 

2.
Delivery of Payment. Optionee herewith delivers to the Company the full purchase price of the Units, as set forth in the
Agreement, and any and all withholding taxes due in connection with the exercise of the Option.

 

3.
Representations of Optionee; Joinder to LLC Agreement. Optionee acknowledges that Optionee has received, read and understood
the Plan, the LLC Agreement and the Option Agreement and agrees to abide by and be bound by their terms and conditions. Without
limiting the foregoing, the Optionee hereby agrees to be bound by and subject to all of the terms and conditions of the LLC Agreement
as a “Member” of the Company.

 

4.
Rights as Member. Until the issuance of the Units (as evidenced by the appropriate entry on the books of the Company or
of a duly authorized transfer agent of the Company), no right to vote (as applicable) or receive distributions or allocations
of profits or losses or any other rights as a Member shall exist with respect to the Units, notwithstanding the exercise of the
Option. The Units shall be issued to the Optionee as soon as practicable after the Option is exercised. No adjustment shall be
made for a dividend or other right for which the record date is prior to the date of issuance except as provided in Section 13
of the Plan.

 

5.
Company’s Right of First Refusal. In addition to any limitations set forth in the LLC Agreement, before any Units
held by Optionee or any transferee (either being sometimes referred to herein as the “Holder”) may be
sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right
of first refusal to purchase the Units on the terms and conditions set forth in this Section (the “Right of First
Refusal”).

 

(a)
Notice of Proposed Transfer. The Holder of the Units shall deliver to the Company a written notice (the “Notice”)
stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Units; (ii) the name of each proposed purchaser
or other transferee (“Proposed Transferee”); (iii) the number of Units to be transferred to each Proposed
Transferee; and (iv) the bona fide cash price or other consideration for which the Holder proposes to transfer the Units (the
“Offered Price”), and the Holder shall offer the Units at the Offered Price to the Company or its assignee(s).

 

    	 

    	 

    

 

(b)
Exercise of Right of First Refusal. At any time within thirty (30) days after receipt of the Notice, the Company and/or
its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Units proposed
to be transferred to any one or more of the Proposed Transferees, at the purchase price determined in accordance with subsection
(c) below.

 

(c)
Purchase Price. The purchase price (“Purchase Price”) for the Units purchased by the Company
or its assignee(s) under this Section 5 shall be the Offered Price. If the Offered Price includes consideration other than cash,
the cash equivalent value of the non-cash consideration shall be determined by the Board of Directors of the Company in good faith.

 

(d)
Payment. Payment of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check),
by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase
by an assignee, to the assignee), or by any combination thereof within thirty (30) days after receipt of the Notice or in the
manner and at the times set forth in the Notice.

 

(e)
Holder’s Right to Transfer. If all of the Units proposed in the Notice to be transferred to a given Proposed Transferee
are not purchased by the Company and/or its assignee(s) as provided in this Section 5, then the Holder may sell or otherwise transfer
such Units to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer
is consummated within 120 days after the date of the Notice, that any such sale or other transfer is effected in accordance with
any applicable securities laws and that the Proposed Transferee agrees in writing that the provisions of this Section 5 shall
continue to apply to the Units in the hands of such Proposed Transferee. If the Units described in the Notice are not transferred
to the Proposed Transferee within such period, a new Notice shall be given to the Company, and the Company and/or its assignees
shall again be offered the Right of First Refusal before any Units held by the Holder may be sold or otherwise transferred.

 

(f)
Exception for Certain Family Transfers. Anything to the contrary contained in this Section 5 notwithstanding, the transfer
of any or all of the Units during the Optionee’s lifetime or on the Optionee’s death by will or intestacy to the Optionee’s
immediate family or a trust for the benefit of the Optionee’s immediate family shall be exempt from the provisions of this
Section 5. “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father,
mother, brother or sister. In such case, the transferee or other recipient shall receive and hold the Units so transferred subject
to the provisions of this Section 5, and there shall be no further transfer of such Units except in accordance with the terms
of this Section 5.

 

(g)
Termination of Right of First Refusal. The Right of First Refusal shall terminate as to any Units upon the earlier of (i)
the first sale of Company common stock to the general public pursuant to a registration statement filed with and declared effective
by the Securities and Exchange Commission under the Securities Act of 1933, as amended, (ii) a Change of Control Event in which
the successor corporation has equity securities that are publicly traded, or (iii) such other date as may be provided by the terms
of the LLC Agreement.

 

6.
Tax Consultation. Optionee understands that Optionee may suffer adverse tax consequences as a result of Optionee’s
purchase or disposition of the Units. Optionee represents that Optionee has consulted with any tax consultants Optionee deems
advisable in connection with the purchase or disposition of the Units and that Optionee is not relying on the Company for any
tax advice.

7.
Restrictive Legends and Stop-Transfer Orders.

 

(a)
Legends. Optionee understands and agrees that the Company shall cause the legends set forth below or legends substantially
equivalent thereto, to be placed upon any certificate(s) (if applicable) evidencing ownership of the Units together with any other
legends that may be required by the Company or by state or federal securities laws:

 

THE
SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”)
AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN
THE OPINION OF COMPANY COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION
IS IN COMPLIANCE THEREWITH.

 

THE
UNITS REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST REFUSAL HELD BY THE
ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE UNITS, A COPY
OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS AND RIGHT OF FIRST REFUSAL ARE BINDING
ON TRANSFEREES OF THESE UNITS.

 

THE
UNITS REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER FOR A PERIOD OF TIME FOLLOWING THE EFFECTIVE DATE
OF THE UNDERWRITTEN PUBLIC OFFERING OF THE COMPANY’S SECURITIES SET FORTH IN AN AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL
HOLDER OF THESE UNITS AND MAY NOT BE SOLD OR OTHERWISE DISPOSED OF BY THE HOLDER PRIOR TO THE EXPIRATION OF SUCH PERIOD WITHOUT
THE CONSENT OF THE COMPANY OR THE MANAGING UNDERWRITER.

 

(b)
Stop-Transfer Notices. Optionee agrees that, in order to ensure compliance with the restrictions referred to herein, the
Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company
transfers its own securities, it may make appropriate notations to the same effect in its own records.

 

(c)
Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Units that have been sold or otherwise
transferred in violation of any of the provisions of this Exercise Notice or (ii) to treat as owner of such Units or to accord
the right to vote or pay dividends to any purchaser or other transferee to whom such Units shall have been so transferred.

 

8.
Successors and Assigns. The Company may assign any of its rights under this Exercise Notice to single or multiple assignees,
and this Exercise Notice shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions
on transfer herein set forth, this Exercise Notice shall be binding upon Optionee and his or her heirs, executors, administrators,
successors and assigns.

 

9.
Interpretation. Any dispute regarding the interpretation of this Exercise Notice shall be submitted by Optionee or by the
Company forthwith to the Administrator which shall review such dispute at its next regular meeting. The resolution of such a dispute
by the Administrator shall be final and binding on all parties.

10.
Governing Law; Severability. This Exercise Notice is governed by the laws of Delaware. In the event that any provision
hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Exercise Notice
will continue in full force and effect.

 

11.
Entire Agreement. The Plan, LLC Agreement, and Option Agreement are incorporated herein by reference. This Exercise Notice,
the Plan, the LLC Agreement, the Option Agreement and the Investment Representation Statement constitute the entire agreement
of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements
of the Company and Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s
interest except by means of a writing signed by the Company and Optionee.

	SECURITY:	 	UNITS (the “Securities”)
	 	 	 
	AMOUNT:	 	_____________
	 	 	 
	DATE:	 	___________, 20__

 

In
connection with the purchase of the above-listed Securities, the undersigned Optionee represents to the Company the following:

 

(a)
Optionee is aware of the Company’s business affairs and financial condition and has acquired sufficient information about
the Company to reach an informed and knowledgeable decision to acquire the Securities. Optionee is acquiring these Securities
for investment for Optionee’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 of 1933, as amended (the “Securities Act”).

 

(b)
Optionee acknowledges and understands that the Securities constitute “restricted securities” under the Securities
Act and have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends
upon, among other things, the bona fide nature of Optionee’s investment intent as expressed herein. In this connection,
Optionee understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be
unavailable if Optionee’s representation was predicated solely upon a present intention to hold these Securities for the
minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market
price of the Securities, or for a period of one year or any other fixed period in the future. Optionee further 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. Optionee further acknowledges and understands that the Company is under no obligation to register
the Securities. Optionee understands that the certificate evidencing the Securities (if applicable) will be imprinted with a legend
which prohibits the transfer of the Securities unless they are registered or such registration is not required in the opinion
of counsel satisfactory to the Company and any other legend required under applicable state securities laws.

 

(c)
Optionee is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance,
permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof,
in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under
Rule 701 at the time of the grant of the Option to the Optionee, the exercise will be exempt from registration under the Securities
Act. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange
Act of 1934, ninety (90) days thereafter (or such longer period as any market stand-off agreement may require) the Securities
exempt under Rule 701 may be resold, subject to the satisfaction of the applicable conditions specified by Rule 144, including
in the case of affiliates (1) the availability of certain public information about the Company, (2) the amount of Securities being
sold during any three (3) month period not exceeding specified limitations, (3) the resale being made in an unsolicited “broker’s
transaction,” transactions directly with a “market maker” or “riskless principal transactions” (as
those terms are defined under the Securities Exchange Act of 1934) and (4) the timely filing of a Form 144, if applicable.

 

    	 

     

    

 

In
the event that the Company does not qualify under Rule 701 at the time of grant of the Option, then the Securities may be resold
in certain limited circumstances subject to the provisions of Rule 144, which may require (i) the availability of current public
information about the Company; (ii) the resale to occur more than a specified period after the purchase and full payment (within
the meaning of Rule 144) for the Securities; and (iii) in the case of the sale of Securities by an affiliate, the satisfaction
of the conditions set forth in sections (2), (3) and (4) of the paragraph immediately above.

 

(d)
Optionee further understands that in the event all of the applicable requirements of Rule 701 or 144 are not satisfied, registration
under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding
the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion
that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an exemption from registration is available for
such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own
risk. Optionee understands that no assurances can be given that any such other registration exemption will be available in such
event.
