pursuant to Ruthigen’s 2013 Employee, Director and Consultant Equity Incentive Plan (the “Plan”)
and Restricted Stock Unit Award Grant Notice (the “Grant Notice”). Such Shares shall vest in accordance
with the vesting schedule set forth in the Grant Notice and otherwise in accordance with the Plan and the Employment Agreement.
Each date that a portion of the Shares vests is referred to herein as a “Vesting Date.” As used herein,

above and in the Grant Notice and “Unvested Shares” refers to any Shares that are not Vested Shares.
Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Employment Agreement. 

 

As a condition to and in
consideration of the grant of the Shares, Harish hereby agrees as follows:

 

1.          Without
limiting the terms of the Plan or the Grant Notice, Harish hereby covenants and agrees that, except as provided herein, he shall
not, without the prior written consent of the Company (i) offer, sell, offer to sell, contract to sell, hedge, pledge, sell any
option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or sell
(or announce any offer, sale, offer of sale, contract of sale, hedge, pledge, sale of any option or contract to purchase, purchase
of any option or contract of sale, grant of any option, right or warrant to purchase or other sale or disposition), or otherwise
transfer or dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition
by any person at any time in the future), any of the Unvested Shares, or any securities into or for which any of the Unvested Shares
may be converted, exercised or exchanged, whether by operation of law or otherwise; or (ii) enter into any swap or other agreement
or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of any of
the Unvested Shares (whether any such swap or other transaction described in clause (i) or (ii) above is to be settled by delivery
of any of the Unvested Shares).

 

2.          Harish
hereby covenants and agrees that, except as provided herein, he shall not, without the prior
written consent of the Company (i) offer, sell, offer to sell, contract to sell, hedge, pledge, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or sell (or announce any offer,
sale, offer of sale, contract of sale, hedge, pledge, sale of any option or contract to purchase, purchase of any option or contract
of sale, grant of any option, right or warrant to purchase or other sale or disposition), or otherwise transfer or dispose of (or
enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any
time in the future), any of the Vested Shares, or any securities into or for which any of the Vested Shares may be converted, exercised
or exchanged, whether by operation of law or otherwise; or (ii) enter into any swap or other agreement or any transaction that
transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of any of the Vested Shares (whether
any such swap or other transaction described in clause (i) or (ii) above is to be settled by delivery of any of the Shares), until
the date that is six months after such Vested Shares have been delivered pursuant to the Employment Agreement.

 

The parties further acknowledge
and agree that the foregoing restriction shall preclude Harish from engaging in any hedging or other transaction which is designed
to, or which reasonably could be expected to or result in a sale or disposition of the Shares, even if such Shares would be disposed
of by any party other than Harish.  Such prohibited hedging or other transactions would include, without limitation, any short
sale or any purchase, sale or grant of any right (including, without limitation, any put or call option) with respect to any of
the Shares, or with respect to any security that includes, relates to or derives any significant part of its value from such Shares.

 

    	 

    	 

    

  

3.           Notwithstanding
the foregoing, Harish may: (A) transfer any of the Vested Shares (after such shares have been delivered pursuant to the Employment
Agreement) (i) as a bona fide gift, provided that, prior to such transfer, the donee thereof agrees in writing to be bound
by the restrictions set forth in this agreement; (ii) to any trust, partnership, corporation or other entity formed for the direct
or indirect benefit of Harish or Harish’s immediate family (as defined below), provided that, prior to such transfer,
a duly authorized officer, representative or trustee of such transferee agrees in writing to be bound by the restrictions set forth
in this agreement, and provided further that any such transfer shall not involve a disposition for value; or (iii) if such transfer
occurs by operation of law, such as rules of descent and distribution, statutes governing the effects of a merger or a qualified
domestic order; and (B) at any time, sell a number of Vested Shares (after such shares have been delivered pursuant to the Employment
Agreement) (i) with an aggregate fair market value (determined based on the sale price Harish receives from a third party for such
Vested Shares) equal to the income and employment tax withholding due with respect to any Vested Shares; or (ii) in a privately
negotiated transactions; provided that, in any case other than in connection with clause (B)(i), prior to such transfer,
the transferee agrees in writing that such transferee is receiving and holding any of the Shares subject to the provisions of this
agreement. For purposes hereof, “immediate family” shall mean any relationship by blood, marriage or adoption, not
more remote than first cousin.

 

In order to enable the
aforesaid covenants to be enforced, Harish hereby consents to the placing of legends and/or entry of stop transfer instructions
or orders with the Company’s transfer agent in respect of any Shares.

EMPLOYMENT AGREEMENT

 

This Employment Agreement (the “Agreement”),
dated as of March 13, 2015, is made and entered into by and between Ruthigen, Inc. a Delaware corporation (“Ruthigen”)
and Pulmatrix, a Delaware corporation (“Pulmatrix”) (collectively “Employer”)
and Hojabr Alimi (“Employee” or “Alimi”).

 

WHEREAS, upon the Effective Time, Employee
is not a director or officer of Employer;

 

WHEREAS, Alimi and Ruthigen are parties
to an Amended and Restated Employment Agreement dated November 28, 2014 (the “Prior Employment Agreement”);

 

WHEREAS, pursuant to an Agreement and
Plan of Merger (the “Merger Agreement”), Ruthigen and Pulmatrix Inc. (including their affiliates and
subsidiaries) have agreed to consummate the merger of Ruthigen Merger Corp, a wholly-owned subsidiary of Ruthigen, with and into
Pulmatrix with Pulmatrix as the surviving corporation (the merger process herein referred to as the “Merger”);

 

WHEREAS, the Prior Employment Agreement
will be terminated as of the date the Merger becomes effective thereunder (the “Effective Time”); and

 

WHEREAS, Pulmatrix is a Delaware corporation
with its primary headquarters located in Massachusetts;

 

NOW, THEREFORE, for good and valuable
consideration, receipt of which is hereby acknowledged, Alimi and Employer agree as follows:

 

1.          Term
of Agreement. As of the Effective Time, this Agreement shall be binding upon and enforceable
against the parties and will remain in effect until the first yearly anniversary of the Effective Time (“Term
of Agreement”). This Agreement may only be terminated during the Term of Agreement
with advance Employee written consent or if Alimi: (i) is convicted of, or has pled guilty to, a felony (under the laws of the
United States or any state thereof); (ii) has engaged in acts of fraud, material dishonesty or other acts of willful misconduct
in the course of his duties hereunder, unless Alimi believes in good faith that such acts were in the interests of Employer; (iii)
has materially violated this Agreement and has not cured such violation within fourteen (14) days of written notice from Employer;
or (iv) willfully fails to comply with reasonable directives of Employer which are communicated to him in writing, and which Employee
fails to correct within seven (7) days of such communication from Employer.

 

2.          Duties
and Wages. Alimi agrees to perform such services as an employee as Employer may reasonably request relating to the transition
of business resulting from the Merger, including without limitation, general corporate matters, matters related to Ruthigen RUT58-60
drug asset, and assisting with the search for potential buyers or licensees of Employer’s core business – Ruthigen
hypochlorous acid based drug candidate (RUT58-60). Alimi shall make himself available to perform these services for up to twenty-four
(24) hours per calendar quarter, on days and at times mutually convenient to the parties, for Restricted Stock Units as described
further below and at a gross hourly rate of twenty-five US dollars ($25.00), less customary tax and other withholdings (the “Wages”).
Employee shall submit accurate records of time worked in accordance with Employer’s policies and procedures and shall be
paid in accordance with Employer’s standard payroll schedule. The parties agree that Employee is not authorized to work more
than eight (8) hours per day or more than forty (40) hours per week, unless Employer expressly otherwise directs and Employee agrees.
Any further work requested by Employer and mutually agreed by Employee shall be subject to additional compensation, which must
be mutually agreed by both parties.

 

Employee is authorized to incur reasonable expenses
in carrying out Employee’s duties for Employer under this Agreement and entitled to reimbursement for all such expenses.
Any expense above one-hundred US dollars ($100) shall require pre-approval by Employer.

 

Employee shall report directly to Robert Clarke
(CEO), and provide monthly reports for completed projects.

 

    	 

    	 

    

  

Employer agrees that no relocation is required
for the Employee to conduct and perform his duties under this Agreement. Furthermore, Employer agrees this Agreement is non-exclusive
and Employee may work or consult for other businesses in accordance with Section 4 of this Agreement.

 

3.          Outstanding
Stock-based Incentive Compensation. Upon the Effective Time, subject to Section 5.1, any and all unvested stock options
granted by Ruthigen to Alimi outstanding as of the Effective Time (the “Outstanding Options”) shall thereupon
be terminated and forfeited. Subject to Section 5.1 and Section 7, any and all unvested restricted stock units granted by Ruthigen
to Alimi outstanding prior to the Effective Time (the “Outstanding RSUs”) shall be terminated and forfeited.

 

4.          Noncompetition;
Nonsolicitation. Commencing on the Effective Time and ending on the date that is one calendar year immediately following the
Effective Time (“Term”), provided, however, that in the event that it is judicially determined that Alimi
has breached materially any provision of this Section 4, the Term applicable to each obligation that Alimi shall have been determined
to have breached shall be automatically extended by a number of days equal to the total number of days in the period from the date
on which such breach shall have first occurred through the date as of which such breach shall have been fully cured, Alimi shall
not anywhere throughout primarily Canada, Europe, Japan, and the United States where Employer will be conducting the Business (as
defined below) (the “Territory”), for himself/herself or through or on behalf of any other person, whether
as an officer, director, employee, equity holder, partner, consultant, advisor, creditor or otherwise:

 

(a)          (i)
engage in, participate in or acquire any financial or beneficial interest in (which for the avoidance of doubt will include employment
with or engagement as an independent contractor for), any business that is engaged in any hypochlorous acid based technology, or
HOCL, based therapies that are designed to prevent and/or treat infections in post-operative invasive surgery including but not
limited to Puricor and Novabay Pharmaceuticals (collectively the “Business”). Nothing in Section 1(a)(i)
shall prevent Alimi from (A) owning as a passive investment less than two percent of the outstanding shares of the capital stock
(or ownership interests) of a publicly held company, if Alimi is not otherwise associated directly or indirectly with such company
or any affiliate of such company or (B) with the consent of Employer (not to be unreasonably withheld), providing services on a
volunteer basis (including, but not limited to, service on boards of director), or (ii) take any action intended to, or that would
reasonably be expected to, negatively affect any commercial relationship of Employer, related to the Business with any other person;

 

(b)          encourage,
induce, attempt to induce, solicit or attempt to solicit any employee to leave his or her employment with Employer, (it being understood
that the placement of general advertisements that may be targeted to a particular geographic or technical area but which are not
targeted directly or indirectly towards an employee, shall not be deemed to be a breach of this Section 1(b)); or

 

(c)          encourage,
induce, attempt to induce, solicit or attempt to solicit any customer of Employer, to cease its customer relationship with Employer
with respect to the Business.

 

5.          Consideration:
In addition to the employment with Employer offered herein, the following additional consideration, which is separate and divisible
and on its own also sufficient to support the non-competition and non-solicitation provision set forth in Section 4:

 

5.1.          On
the Effective Time, Employer shall pay Alimi a lump-sum payment in the amount of $547,600, less taxes and other withholdings, as
payment in exchange for cancellation of Employee’s Outstanding Options and Outstanding RSUs and Employee shall execute a
Cancellation Agreement, in substantially the form attached hereto as Exhibit A. By that date, Employer also shall pay an
amount in lump-sum equivalent to one hundred percent of Alimi’s premiums under the Consolidated Omnibus Budget Reconciliation
Act for one year, in the same amounts for the same medical coverage as in effect as of the Effective Time.

 

    	 

    	 

    

  

5.2.  On the Effective
Time, Alimi shall also receive a grant of such number of restricted stock units, pursuant to Employer’s 2013 Employee, Director
and Consultant Equity Incentive Plan, equal to the lesser of (i) 930,000 or (ii) the quotient of $3,125,000 divided by the fair
market value of Employer’s Common Stock on the Effective Time, based on PWC’s valuation on such date following consultation
with Alimi (the “New RSUs”). Such New RSUs shall be vested and delivered in accordance with Employer’s
equity plan and an applicable award agreement, which shall include the following schedule: (i) a number of New RSUs equal to the
lesser of (a) 930,000 or (b) such number of RSUs with an aggregate value equal to $1,400,000 shall be fully vested at the Effective
Time and the underlying shares shall be delivered to Employee on the first trading day following the first anniversary of the Effective
Time; (ii) 25% of the New RSUs that were not fully vested on the Effective Time shall vest on the first business day of the third
(3rd) month following the Effective Time and the underlying shares shall be delivered on the first trading day following
the fifteenth (15th) month anniversary of the Effective Time; (iii) an additional 25% of the New RSUs that were not
fully vested on the Effective Time shall vest on the first business day of the sixth (6th) month anniversary of the
Effective Time and the underlying shares shall be delivered on the first trading day following the eighteenth (18th)
month anniversary of the Effective Time; (iv) an additional 25% of the New RSUs that were not fully vested on the Effective Time
shall vest on the first business day of the ninth (9th) month anniversary of the Effective Time and the underlying shares
shall be delivered on the first trading day following the twenty-first (21st) month anniversary of the Effective Time
and (v) the remaining 25% of the New RSUs that were not fully vested on the Effective Time shall vest on the first business day
of the twelfth (12th) month following the Effective Time, and the underlying shares shall be delivered on the first
trading day following the twenty-fourth (24th) month anniversary of the Effective Time. In the event Employer sells,
terminates, or disposes of the hypochlorous acid asset, or HOCl based drug asset (RUT58-60), Employer will cause the buyer or benefactor
to assume the obligations under this Agreement, and all remaining unvested New RSUs will fully vest and the obligations under this
Agreement would transfer to the buyer or benefactor. In the event Employee terminates this Agreement, all remaining unvested New
RSUs will be forfeited. All shares of stock delivered pursuant to the New RSUs shall be subject to that certain lock-up agreement,
of even date herewith, attached hereto as Exhibit B (“Lock-Up Agreement”). The withholding required
by Section 7 below shall be delivered by Employee to Employer on the day Employee takes possession of the stock. Employer shall
register the New RSUs with the Securities and Exchange Commission under a Registration Statement on Form S-8 which Employer shall
cause to remain effective until the earlier of (i) the time that all of the shares underlying the New RSUs have been sold by Employee,
(ii) six (6) months following the termination of the Lock-Up Agreement or (iii) such time as Employer is not subject to the requirement
to file reports pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended.

 

6.          Separate
Non-compete.  Employee must execute an additional, separate non-compete agreement with Oculus Innovative Sciences, Inc.,
attached as Exhibit B, as a condition precedent to the closing of the Merger.

 

7.          Withholding
Tax. The delivery of any shares in connection with the New RSUs, is subject to and conditioned upon Alimi satisfying the income
and employment withholding obligations due with respect to any ordinary income recognized in connection with the delivery of such
shares. Alimi acknowledges and understands that if he fails to satisfy the withholding obligations with respect to the New RSUs,
Employer will have no obligation to deliver any shares of Common Stock to Employee with respect to the portion of the New RSUS
for which Employee fails to deliver the required withholding, as applicable, and he will forfeit his right to receive such New
RSUs, as applicable. Notwithstanding anything to the contrary herein, Employee’s failure to pay any withholding due with
respect to one tranche of New RSUs shall not impact his right to receive shares of Common Stock underlying any other tranches of
New RSUs.

 

8.          Prior
Employment Agreement. As of the Effective Time, the Prior Employment Agreement between the parties shall terminate, except
that Alimi acknowledges and agrees that Section 8 Confidentiality, Section 9 Inventions and Developments,
Section 12 Return of Property, and Section 14 Cooperation in Litigation of the Prior Employment Agreement,
and all provisions thereunder, shall remain in full force and effect in accordance with their terms and shall be incorporated into
this Agreement as if to apply in an equivalent manner to any further services Alimi provides hereunder; provided however that in
no event will these obligations, with the exception of those set forth in Section 14 Cooperation in Litigation, continue
past the end of the Term of Agreement as defined in Section 1 herein. The parties also agree that any obligations to indemnify
Alimi as set forth in the Prior Employment Agreement shall be incorporated herein and Employer’s obligations to indemnify
Alimi in Employer’s certificate of incorporation and bylaws shall remain in effect.

 

    	 

    	 

    

  

9.          Governing
Law/Venue. The parties agree that this Agreement shall be governed by and construed exclusively under the laws of the Commonwealth
of Massachusetts. Venue of any litigation arising from this Agreement or any disputes relating to Alimi’s employment and
non-competition /-non-solicitation obligations set forth in Sections 4 and 5 herein shall exclusively be in the federal or state
district court of competent jurisdiction in the Commonwealth of Massachusetts. Alimi consents to personal jurisdiction of any such
court for any dispute relating to or arising out of this Agreement or Alimi’s employment, and Alimi agrees that Alimi shall
not challenge personal or subject matter jurisdiction in such courts. To the extent that any party hereto has claims that could
be brought in or adjudicated under the laws of any jurisdiction other than Massachusetts, the parties expressly hereby waive all
such rights.

 

10.         Voluntary.
This Agreement is executed voluntarily and without any duress or undue influence on the part or behalf of the parties hereto. The
parties acknowledge that they have had ample opportunity to have this Agreement reviewed by the counsel of their choice.

 

11.         Sole
Agreement. Except as set forth herein, this Agreement is the sole, entire and complete agreement of the parties relating to
Alimi’s employment with Employer subsequent to the Effective Time, and it supersedes and fully replaces any prior agreements
(whether written or oral) covering the subject matter of this Agreement. No changes in or additions to this Agreement shall be
recognized, unless incorporated in this Agreement by written amendment signed by all parties hereto. No statements, promises or
representations have been made by any party to any other party, or relied upon, and no consideration has been offered, promised,
expected or held out other than as expressly set forth herein, provided only that the release of claims in any prior agreement
or release shall remain in full force and effect.

 

12.         No
Assignment. In entering into this Agreement, Employer is relying on the unique personal services of Alimi; services from another
person will not be an acceptable substitute. Except as provided in this Agreement, neither party may assign this Agreement or any
of the rights or obligations set forth in this Agreement without the explicit advance written consent of the other party. Any attempted
assignment in violation of this Section 12 shall be void. The provisions of this Agreement shall be binding upon and shall inure
to the benefit of Employer and its successors and assigns. Employer agrees that this Agreement shall survive any change with respect
to the ownership of the assets of Employer (e.g., sell, sub-license, termination, return of the assets to prior owners, etc.) or
any other business development deal.

 

13.         Severability.
The covenants contained in this Agreement are intended by the parties hereto as separate and divisible provisions, and in the event
that any or all of the covenants expressed herein shall be determined by a court of competent jurisdiction to be invalid or unenforceable,
the remaining parts, terms or provisions of this Agreement shall not be affected and such provisions shall remain in full force
and effect. The parties intend all provisions of this Agreement to be enforced to the fullest extent permitted by law. If, however,
any provision of this Agreement is held to be illegal, invalid, or unenforceable under present or future law, such provision shall
be fully severable, and this Agreement shall be construed and enforced as if such illegal, invalid, or unenforceable provision
were never a part hereof, and the remaining provisions shall remain in full force and effect and shall not be affected by the illegal,
invalid, or unenforceable provision or by its severance. In lieu of such illegal, invalid or unenforceable provision, there shall
be added automatically as a part of this Agreement a legal, valid and enforceable provision as similar in terms to such illegal,
invalid or unenforceable provision as may be possible, and the parties hereby request the court to whom disputes relating to this
Agreement are submitted to reform the otherwise unenforceable covenant in accordance with this Section.

 

14.         Notices.
All notices, requests and other communications required or permitted under, or otherwise made in connection with, this Agreement,
shall be in writing and shall be deemed to have been duly given (a) when delivered in person, (b) upon confirmation of receipt
when transmitted by facsimile transmission, (c) upon receipt after dispatch by registered or certified mail, postage prepaid, or
(d) on the next business day if transmitted by national overnight courier (with confirmation of delivery), in each case, addressed
as follows:

Reference
is hereby made to that certain Employment Agreement (the “Employment Agreement”), of even date herewith,
between Hojabr Alimi (“Alimi”) and Ruthigen, Inc., a Delaware corporation (the “Company”),
and its affiliates, pursuant to which, among other things, the Company shall grant to Alimi at the Effective Time (as defined
in the Employment Agreement) up to 930,000 restricted stock units (the “Shares”) pursuant to Ruthigen’s
2013 Employee, Director and Consultant Equity Incentive Plan (the “Plan”) and Restricted Stock Unit Award
Grant Notice (the “Grant Notice”). Such Shares shall vest in accordance with the vesting schedule set
forth in the Grant Notice and otherwise in accordance with the Plan and the Employment Agreement. Each date that a portion of the
Shares vests is referred to herein as a “Vesting Date.” As used herein, “Vested Shares”
refers to any Shares that have vested in accordance with the vesting schedule set forth above and in the Grant Notice and “Unvested
Shares” refers to any Shares that are not Vested Shares. Capitalized terms used herein and not otherwise defined
shall have the meanings set forth in the Employment Agreement.

 

As a condition to and in
consideration of the grant of the Shares, Alimi hereby agrees as follows:

 

		1.	Without limiting the terms of the Plan or the Grant Notice, Alimi hereby covenants and agrees that,
except as provided herein, he shall not, without the prior written consent of the Company (i) offer, sell, offer to sell, contract
to sell, hedge, pledge, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right
or warrant to purchase or sell (or announce any offer, sale, offer of sale, contract of sale, hedge, pledge, sale of any option
or contract to purchase, purchase of any option or contract of sale, grant of any option, right or warrant to purchase or other
sale or disposition), or otherwise transfer or dispose of (or enter into any transaction or device that is designed to, or could
be expected to, result in the disposition by any person at any time in the future), any of the Unvested Shares, or any securities
into or for which any of the Unvested Shares may be converted, exercised or exchanged, whether by operation of law or otherwise;
or (ii) enter into any swap or other agreement or any transaction that transfers, in whole or in part, directly or indirectly,
the economic consequence of ownership of any of the Unvested Shares (whether any such swap or other transaction described in clause
(i) or (ii) above is to be settled by delivery of any of the Unvested Shares).

 

		2.	Alimi hereby covenants and agrees that, except as provided herein, he
shall not, without the prior written consent of the Company (i) offer, sell, offer to sell, contract to sell, hedge, pledge, sell
any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or
sell (or announce any offer, sale, offer of sale, contract of sale, hedge, pledge, sale of any option or contract to purchase,
purchase of any option or contract of sale, grant of any option, right or warrant to purchase or other sale or disposition), or
otherwise transfer or dispose of (or enter into any transaction or device that is designed to, or could be expected to, result
in the disposition by any person at any time in the future), any of the Vested Shares, or any securities into or for which any
of the Vested Shares may be converted, exercised or exchanged, whether by operation of law or otherwise; or (ii) enter into any
swap or other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence
of ownership of any of the Vested Shares (whether any such swap or other transaction described in clause (i) or (ii) above is to
be settled by delivery of any of the Shares), until the date that is six months after such Vested Shares have been delivered pursuant
to the Employment Agreement. 

 

The parties further acknowledge
and agree that the foregoing restriction shall preclude Alimi from engaging in any hedging or other transaction which is designed
to, or which reasonably could be expected to or result in a sale or disposition of the Shares, even if such Shares would be disposed
of by any party other than Alimi.  Such prohibited hedging or other transactions would include, without limitation, any short
sale or any purchase, sale or grant of any right (including, without limitation, any put or call option) with respect to any of
the Shares, or with respect to any security that includes, relates to or derives any significant part of its value from such Shares.

 

    	 

    	 

    

 

 

3.           Notwithstanding
the foregoing, Alimi may: (A) transfer any of the Vested Shares (after such shares have been delivered pursuant to the Employment
Agreement) (i) as a bona fide gift, provided that, prior to such transfer, the donee thereof agrees in writing to be bound
by the restrictions set forth in this agreement; (ii) to any trust, partnership, corporation or other entity formed for the direct
or indirect benefit of Alimi or Alimi’s immediate family (as defined below), provided that, prior to such transfer,
a duly authorized officer, representative or trustee of such transferee agrees in writing to be bound by the restrictions set forth
in this agreement, and provided further that any such transfer shall not involve a disposition for value; or (iii) if such transfer
occurs by operation of law, such as rules of descent and distribution, statutes governing the effects of a merger or a qualified
domestic order; and (B) at any time, sell a number of Vested Shares (after such shares have been delivered pursuant to the Employment
Agreement) (i) with an aggregate fair market value (determined based on the sale price Alimi receives from a third party for such
Vested Shares) equal to the income and employment tax withholding due with respect to any Vested Shares; or (ii) in a privately
negotiated transactions; provided that, in any case other than in connection with clause (B)(i), prior to such transfer,
the transferee agrees in writing that such transferee is receiving and holding any of the Shares subject to the provisions of this
agreement. For purposes hereof, “immediate family” shall mean any relationship by blood, marriage or adoption, not
more remote than first cousin.

 

In order to enable the
aforesaid covenants to be enforced, Alimi hereby consents to the placing of legends and/or entry of stop transfer instructions
or orders with the Company’s transfer agent in respect of any Shares.
