This

hereof (the “Subscriber”) in connection with the private placement offering (the “Offering”)
of a minimum of $2,500,000 (the “Minimum Offering”) and a maximum of $10,000,000 (the “Maximum
Offering”) of Units of securities (the “Units”), plus up to an additional $1,500,000 of Units
to cover over-subscriptions, issued by Shuttle Pharmaceuticals Holdings, Inc., a Delaware corporation (the “Company”),
at a purchase price of $1,000 per Unit (the “Purchase Price”). Each Unit consists of (i) one share of the Company’s
Series A Convertible Preferred Stock, par value $0.00001 per share, with a Stated Value of $1,000 per share (the “Series A Preferred
Stock”), and (ii) a warrant, substantially in the form of Exhibit A hereto (the “Warrant”),
representing the right to purchase a number of shares of the Company’s common stock, par value $0.00001 per share (“Common
Stock”), equal to the number of shares into which a share of Series A Preferred Stock will be converted, with such Warrant
to be issued upon the earlier of (a) the closing of the sale of shares of Common Stock to the public at a price per share of at least
$13.88 (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization
with respect to the Common Stock), in a firm commitment underwritten public offering pursuant to an effective registration statement
under the Securities Act, resulting in gross proceeds (before underwriters’ discount, commissions and expenses) to the Company
of at least the difference between $15,000,000 and the gross proceeds of this Offering (a “Qualified IPO”),
or (b) listing (a “Listing”) of the Common Stock on the New York Stock Exchange, NYSE American, Nasdaq Global
Select Market, Nasdaq Global Market or Nasdaq Capital Market (a “Qualified Exchange”). Such Warrant shall be
exercisable for a period of three (3) years from the date of issuance at the per share price of the Company’s initial public offering
(“IPO”) or, if a Qualified IPO has not yet occurred, at $20.82/per share. Each share of Series A Preferred Stock is
convertible into shares of Common Stock (the “Conversion Shares”) at a conversion price and on the other terms
set forth in the Certificate of Designations (as defined below). The certificate of designations setting forth the resolution of the
Board of Directors of the Company establishing the Series A Preferred Stock and stating the number of authorized shares thereof and the
voting powers, designations, preferences, limitations, restrictions and relative rights of the Series A Preferred Stock (the “Certificate
of Designations”) shall be substantially in the form of Exhibit B hereto.


 


The
minimum subscription is $50,000 (50 Units). The Company may accept subscriptions for less than $50,000 in its sole discretion.


 


The
Units being subscribed for pursuant to this Agreement have not been registered under the Securities Act of 1933, as amended (the “Securities
Act”). The Offering is being made on a reasonable best efforts basis to “accredited investors,” as defined
in Regulation D under the Securities Act in reliance upon the exemption from securities registration afforded by Section 4(a)(2) of the
Securities Act and Rule 506 of Regulation D. The Subscriber acknowledges receipt of a copy of the Registration Rights Agreement, substantially
in the form of Exhibit C hereto (the “Registration Rights Agreement”).

		c.	Company
                                            Discretion. The Subscriber understands and agrees that the Company in its sole discretion
                                            reserves the right to accept or reject this or any other subscription for Units, in whole
                                            or in part, notwithstanding prior receipt by the Subscriber of notice of acceptance of this
                                            subscription. The Company shall have no obligation hereunder until the Company shall execute

	3.	Placement
                                            Agent. The Company intends to engage a broker-dealer licensed with FINRA as placement
                                            agent (the “Placement Agent”) for the Offering on a reasonable
                                            best efforts basis. The Company anticipates that the Placement Agent and its sub-agents will
                                            be paid at each Closing from the proceeds in the Escrow Account, a cash commission of 8%
                                            of the gross Purchase Price paid by Subscribers in the Offering and will receive warrants
                                            to purchase a number of shares of Common Stock equal to 8% of the number of Conversion Shares
                                            initially issuable upon conversion of the shares of Series A Preferred Stock contained in
                                            the Units sold in the Offering to investors, with a term of three (3) years from the relevant
                                            Closing Date, and at a per share exercise price equal to that of the Warrants issued to the
                                            Subscribers herein (the “Placement Agent Warrants”). Any sub-agent
                                            of the Placement Agent that introduces investors to the Offering will be entitled to share
                                            in the cash fees and Placement Agent Warrants attributable to those investors as described
                                            above, pursuant to the terms of an executed sub-agent agreement). The Company will also pay
                                            certain expenses of the Placement Agent.



 


	4.	Representations
                                            and Warranties of the Company. The Company hereby represents and warrants to the Subscriber,

                                            jurisdiction in which the nature of the business conducted by it makes such qualification
                                            necessary, except to the extent that the failure to be so qualified or be in good standing

                                            to numerous factors beyond the Company’s control. Additionally, the Subscriber understands
                                            and represents that it is purchasing the Units notwithstanding the fact that the Company
                                            may disclose in the future certain material information the Subscriber has not received,
                                            including (without limitation) financial statements of the Company a for the current or prior
                                            fiscal periods, and any subsequent period financial statements that will be filed with the
                                            Securities and Exchange Commission, that it is not relying on any such information in connection
                                            with its purchase of the Units and that it waives any right of action with respect to the
                                            nondisclosure to it prior to its purchase of the Units of any such information. Each Subscriber
                                            has sought such accounting, legal and tax advice as it has considered necessary to make an
                                            informed investment decision with respect to its acquisition of the Units.

                                            Subscriber acknowledges that the Company is not acting as a financial advisor or fiduciary
                                            of the Subscriber (or in any similar capacity) with respect to the Transaction Documents
                                            and the transactions contemplated hereby and thereby and no investment advice has been given

                                            Documents and the transactions contemplated hereby and thereby. The Subscriber further represents
                                            to the Company that the Subscriber’s decision to enter into the Transaction Documents
                                            has been based solely on the independent evaluation by the Subscriber and its representatives.

                                            represents that neither it nor, to its knowledge, any person or entity controlling, controlled
                                            by or under common control with it, nor any person having a beneficial interest in it, nor
                                            any person on whose behalf the Subscriber is acting: (i) is a person listed in the Annex
                                            to Executive Order No. 13224 (2001) issued by the President of the United States (Executive

applicable U.S. anti-money laundering, anti-terrorist and asset control laws, regulations, rules or orders (categories (i) through
(v), each a “Prohibited Subscriber”). The Subscriber agrees to provide the Company, promptly upon request,
all information that the Company reasonably deems necessary or appropriate to comply with applicable U.S. anti-money laundering,
anti-terrorist and asset control laws, regulations, rules and orders. The Subscriber consents to the disclosure to U.S. regulators
and law enforcement authorities by the Company and its affiliates and agents of such information about the Subscriber as the Company
reasonably deems necessary or appropriate to comply with applicable U.S. anti-money laundering, anti- terrorist and asset control
laws, regulations, rules and orders. If the Subscriber is a financial institution that is subject to the USA Patriot Act, the
Subscriber represents that it has met all of its obligations under the USA Patriot Act. The Subscriber acknowledges that if,
following its investment in the Company, the Company reasonably believes that the Subscriber is a Prohibited Subscriber or is
otherwise engaged in suspicious activity or refuses to promptly provide information that the Company requests, the Company has the
right or may be obligated to prohibit additional investments, segregate the assets constituting the investment in accordance with
applicable regulations or immediately require the Subscriber to transfer the Shares, the Conversion Shares, the Warrants and/or the
Warrant Shares. The Subscriber further acknowledges that the Subscriber will have no claim against the Company or any of its
affiliates or agents for any form of damages as a result of any of the foregoing actions.
	 	 	 
	 	 	If
the Subscriber is affiliated with a non-U.S. banking institution (a “Foreign Bank”), or if the Subscriber
receives deposits from, makes payments on behalf of, or handles other financial transactions related to a Foreign Bank, the
Subscriber represents and warrants to the Company that: (1) the Foreign Bank has a fixed address, other than solely an electronic
address, in a country in which the Foreign Bank is authorized to conduct banking activities; (2) the Foreign Bank maintains
operating records related to its banking activities; (3) the Foreign Bank is subject to inspection by the banking authority that
licensed the Foreign Bank to conduct banking activities; and (4) the Foreign Bank does not provide banking services to any other
Foreign Bank that does not have a physical presence in any country and that is not a regulated affiliate.



 








		k.	The
                                            Subscriber or its duly authorized representative recognizes that, as the Company is in its
                                            early stages of development and, as there has yet to develop a public or private market in
                                            the Company’s securities, there can be no assurance that any such market will develop
                                            in the foreseeable future. Furthermore, there can be no assurance that the Company will ever
                                            consummate a public offering or become an SEC-reporting issuer. The Subscriber has carefully
                                            considered such risk before deciding to invest in the Shares.



 


		l.	The
                                            Subscriber has adequate means of providing for its current and anticipated financial needs
                                            and contingencies, is able to bear the economic risk for an indefinite period of time and
                                            has no need for liquidity of the investment in the Units and could afford complete loss of
                                            such investment.

		m.	The
                                            Subscriber is not subscribing for Units as a result of or subsequent to any advertisement,
                                            article, notice or other communication, published in any newspaper, magazine or similar media
                                            or broadcast over television, radio, or the internet, or presented at any seminar or meeting,

                                            in connection with investments in securities generally.



 


		n.	The
                                            Subscriber acknowledges that no U.S. federal or state agency or any other government or governmental
                                            agency has passed upon the Units, the Shares, the Conversion Shares, the Warrants or the
                                            Warrant Shares or made any finding or determination as to the fairness, suitability or wisdom
                                            of any investments therein.



 


		o.	Other
                                            than consummating the transactions contemplated hereunder, the Subscriber has not directly
                                            or indirectly, nor has any individual or entity acting on behalf of or pursuant to any understanding
                                            with such Subscriber, executed any purchases or sales, including Short Sales, of the securities
                                            of the Company during the period commencing as of the time that such Subscriber first received
                                            a term sheet (written or oral) from the Company or any other individual or entity representing
                                            the Company setting forth the material terms of the transactions contemplated hereunder and
                                            ending immediately prior to the execution hereof. Notwithstanding the foregoing, in the case
                                            of a Subscriber that is a multi-managed investment vehicle whereby separate portfolio managers
                                            manage separate portions of such Subscriber’s assets and the portfolio managers have
                                            no direct knowledge of the investment decisions made by the portfolio managers managing other
                                            portions of such Subscriber’s assets, the representation set forth above shall only
                                            apply with respect to the portion of assets managed by the portfolio manager that made the
                                            investment decision to purchase the Shares covered by this Agreement. Other than to other
                                            individuals or entities party to this Agreement, such Subscriber has maintained the confidentiality
                                            of all disclosures made to it in connection with this transaction (including the existence
                                            and terms of this transaction). Notwithstanding the foregoing, for avoidance of doubt, nothing
                                            contained herein shall constitute a representation or warranty, or preclude any actions,
                                            with respect to the identification of the availability of, or securing of, available shares
                                            to borrow in order to effect Short Sales or similar transactions in the future. For purposes
                                            of this Agreement, “Short Sales” means all “short sales”
                                            as defined in Rule 200 of Regulation SHO under the Exchange Act (but shall not be deemed
                                            to include the location and/or reservation of borrowable shares of Common Stock).



 


		p.	The
                                            Subscriber agrees to be bound by all of the terms and conditions of the Registration Rights

		q.	The
                                            Subscriber is aware that the anti-manipulation rules of Regulation M under the Exchange Act
                                            may apply to sales of the Conversion Shares and Warrant Shares and other activities with
                                            respect to such shares held by the Subscriber.



 


		r.	All
                                            of the information concerning the Subscriber set forth herein, and any other information
                                            furnished by the Subscriber in writing to the Company or the Placement Agent for use in connection
                                            with the transactions contemplated by this Agreement, or which is set forth herein is true,

                                            should be any material change in such information prior to the admission of the undersigned
                                            to the Company, the Subscriber will immediately furnish revised or corrected information
                                            to the Company.

		s.	(For
                                            ERISA plans only) The fiduciary of the ERISA plan (the “Plan”)
                                            represents that such fiduciary has been informed of and understands the Company’s investment
                                            objectives, policies and strategies, and that the decision to invest “plan assets”
                                            (as such term is defined in ERISA) in the Company is consistent with the provisions of ERISA
                                            that require diversification of plan assets and impose other fiduciary responsibilities.
                                            The Subscriber fiduciary or Plan (a) is responsible for the decision to invest in the Company;
                                            (b) is independent of the Company or any of its affiliates; (c) is qualified to make such
                                            investment decision; and (d) in making such decision, the Subscriber fiduciary or Plan has
                                            not relied primarily on any advice or recommendation of the Company or any of its affiliates.



 


	6.	Transfer
                                            Restrictions. The Subscriber acknowledges and agrees as follows:



 


		a.	The
                                            Units, the Shares, the Conversion Shares, the Warrants and the Warrant Shares have not been
                                            registered for sale under the Securities Act, in reliance on the private offering exemption
                                            in Section 4(a)(2) thereof; other than as expressly provided for in the Registration Rights
                                            Agreement, the Company does not currently intend to register the Units, the Shares, the Conversion
                                            Shares, the Warrants or the Warrant Shares under the Securities Act at any time in the future;
                                            and the undersigned will not immediately be entitled to the benefits of Rule 144 with respect
                                            to the Units, the Conversion Shares, the Shares, the Warrants and the Warrant Shares.



 


		b.	The
                                            Subscriber understands that there are substantial restrictions on the transferability of
                                            the Shares, the Conversion Shares, the Warrants and the Warrant Shares (collectively, the
                                            “Securities”), that the certificates representing the Securities
                                            shall bear a restrictive legend in substantially the following form (or in the case of the
                                            Warrants, as shown on the form of Warrant attached hereto) (and a stop-transfer order may
                                            be placed against transfer of such certificates or other instruments):



 


THE
SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”), OR ANY STATE SECURITIES LAWS, AND NEITHER SUCH SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, PLEDGED, ASSIGNED
OR OTHERWISE TRANSFERRED UNLESS (1) A REGISTRATION STATEMENT WITH RESPECT THERETO IS EFFECTIVE UNDER THE SECURITIES ACT AND ANY APPLICABLE
STATE SECURITIES LAWS, OR (2) AN EXEMPTION FROM SUCH REGISTRATION EXISTS AND THE COMPANY RECEIVES AN OPINION OF COUNSEL, WHICH COUNSEL
AND OPINION ARE SATISFACTORY TO THE COMPANY, THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED, ASSIGNED OR TRANSFERRED IN THE MANNER
CONTEMPLATED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR APPLICABLE STATE SECURITIES LAWS. HEDGING TRANSACTIONS
INVOLVING THESE SECURITIES MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH THE SECURITIES ACT.


 


In
addition, if any Subscriber is an affiliate of the Company certificates evidencing the Shares issued to such Subscriber may bear a customary
“Affiliates” legend.


 


The
legend set forth above shall be removed and the Company shall issue a certificate without such legend to the holder of the Securities
upon which it is stamped, if (a) such Shares are sold pursuant to a registration statement under the Securities Act, or (b) such holder
delivers to the Company an opinion of counsel, reasonably acceptable to the Company, that a disposition of the Securities is being made
pursuant to an exemption from such registration and that the Securities, after such transfer, shall no longer be “restricted securities”
within the meaning of Rule 144.

		d.	The
                                            arbitrator’s award is not required to include factual findings or legal reasoning and
                                            any party’s right to appeal or to seek modification of rulings by arbitrators is strictly
                                            limited.



 


		e.	The
                                            panel of arbitrators will typically include a minority of arbitrators who were or are affiliated
                                            with the securities industry.



 


		f.	All
                                            controversies which may arise between the parties concerning this Agreement shall be determined
                                            by arbitration pursuant to the rules then pertaining to the Financial Industry Regulatory
                                            Authority in New York City, New York. Judgment on any award of any such arbitration may be
                                            entered in the Supreme Court of the State of New York or in any other court having jurisdiction
                                            of the person or persons against whom such award is rendered. Any notice of such arbitration
                                            or for the confirmation of any award in any arbitration shall be sufficient if given in accordance
                                            with the provisions of this Agreement. The parties agree that the determination of the arbitrators
                                            shall be binding and conclusive upon them. The prevailing party, as determined by such arbitrators,
                                            in a legal proceeding shall be entitled to collect any costs, disbursements and reasonable
                                            attorney’s fees from the other party. Prior to filing an arbitration, the parties hereby
                                            agree that they will attempt to resolve their differences first by submitting the matter
                                            for resolution to a mediator, acceptable to all parties, and whose expenses will be borne
                                            equally by all parties. The mediation will be held in the County of New York, State of New
                                            York, on an expedited basis. If the parties cannot successfully resolve their differences
                                            through mediation, the matter will be resolved by arbitration. The arbitration shall take
                                            place in the County of New York, State of New York, on an expedited basis.

                                            Agreement and the Registration Rights Agreement, it is hereby agreed that the execution by

                                            shall constitute agreement to be bound by the terms and conditions hereof and the terms and
                                            conditions of the Registration Rights Agreement, with the same effect as if each of such
                                            separate but related agreement were separately signed.



 


	23.	Public

                                            stockholder, employee, affiliate, affiliated person or entity of the Subscriber shall make
                                            or issue any press releases or otherwise make any public statements or make any disclosures

                                            not make or issue any press releases or otherwise make any public statements of any nature

                                            Nature of Each Purchaser’s Obligations and Rights. For avoidance of doubt, the
                                            obligations of the Purchaser under this Agreement are several and not joint with the obligations
                                            of any other Purchaser, and the Purchaser shall not be responsible in any way for the performance
                                            of the obligations of any other Purchaser under any other Subscription Agreement. Nothing
                                            contained herein and no action taken by the Purchaser shall be deemed to constitute the Purchaser
                                            as a partnership, an association, a joint venture, or any other kind of entity, or create
                                            a presumption that the Purchasers are in any way acting in concert or as a group with respect
                                            to such obligations or the transactions contemplated by this Agreement and any other Subscription
                                            Agreements. The Purchaser shall be entitled to independently protect and enforce its rights,
                                            including without limitation the rights arising out of this Agreement, and it shall not be
                                            necessary for any other Purchaser to be joined as an additional party in any proceeding for
                                            such purpose.

ANTI
MONEY LAUNDERING REQUIREMENTS


 


The
USA PATRIOT Act


 


The
USA PATRIOT Act is designed to detect, deter, and punish terrorists in the United States and abroad. The Act imposes new anti-money laundering
requirements on brokerage firms and financial institutions. Since April 24, 2002 all brokerage firms have been required to have new,
comprehensive anti-money laundering programs.


 


To
help you understand these efforts, we want to provide you with some information about money laundering and our steps to implement the
USA PATRIOT Act.


 


What
is money laundering?


 


Money
laundering is the process of disguising illegally obtained money so that the funds appear to come from legitimate sources or activities.
Money laundering occurs in connection with a wide variety of crimes, including illegal arms sales, drug trafficking, robbery, fraud,
racketeering, and terrorism.


 


How
big is the problem and why is it important?


 


The
use of the U.S. financial system by criminals to facilitate terrorism or other crimes could well taint our financial markets. According
to the U.S. State Department, one recent estimate puts the amount of worldwide money laundering activity at $1 trillion a year.


 


What
are we required to do to eliminate money laundering?


 


Under
rules required by the USA PATRIOT Act, our anti-money laundering program must designate a special compliance officer, set up employee
training, conduct independent audits, and establish policies and procedures to detect and report suspicious transaction and ensure compliance
with such laws. As part of our required program, we may ask you to provide various identification documents or other information. Until
you provide the information or documents we need, we may not be able to effect any transactions for you.

		3.	CERTAIN
                                            ADJUSTMENTS.



 


(a) Adjustment
of Number of Warrant Shares and Exercise Price. The number and kind of Warrant Shares purchasable upon exercise of this Warrant
and the Exercise Price shall be subject to adjustment from time to time as follows:


 


(1) Subdivisions,
Combinations and Other Issuances. If the Company shall at any time after the Date of Issuance but prior to the Expiration Date
subdivide its shares of capital stock of the same class as the Warrant Shares, by split-up or otherwise, or combine such shares of
capital stock, or issue additional shares of capital stock as a dividend with respect to any shares of such capital stock, the
number of Warrant Shares issuable on the exercise of this Warrant shall forthwith be proportionately increased in the case of a
subdivision or stock dividend, or proportionately decreased in the case of a combination. Appropriate adjustments shall also be made
to the Exercise Price payable per share, but the aggregate Exercise Price payable for the total number of Warrant Shares purchasable
under this Warrant (as adjusted) shall remain the same. Any adjustment under this Section 3(a)(1) shall become effective at
the close of business on the date the subdivision or combination becomes effective, or as of the record date of such dividend, or in
the event that no record date is fixed, upon the making of such dividend.


 


(2) Reclassification,
Reorganizations and Consolidation. In case of any reclassification, capital reorganization or change in the capital stock of the
Company (other than as a result of a subdivision, combination or stock dividend provided for in Section 3(a)(1) above) that
occurs after the Date of Issuance, then, as a condition of such reclassification, reorganization or change, lawful provision shall
be made, and duly executed documents evidencing the same from the Company or its successor shall be delivered to the Warrantholder,
so that the Warrantholder shall thereafter have the right at any time prior to the expiration of this Warrant to purchase, at a
total price equal to that payable upon the exercise of this Warrant, the kind and amount of shares of stock and/or other securities
or property (including, if applicable, cash) receivable in connection with such reclassification, reorganization or change by a
holder of the same number and type of securities as were purchasable as Warrant Shares by the Warrantholder immediately prior to
such reclassification, reorganization or change. In any such case appropriate provisions shall be made with respect to the rights
and interest of the Warrantholder so that the provisions hereof shall thereafter be applicable with respect to any shares of stock
or other securities or property deliverable upon exercise hereof, and appropriate adjustments shall be made to the Exercise Price
payable hereunder, provided the aggregate Exercise Price shall remain the same (and, for the avoidance of doubt, this Warrant shall
be exclusively exercisable for such shares of stock and/or other securities or property from and after the consummation of such
reclassification or other change in the capital stock of the Company).


 




    	-2-



     


    

 


 (b) Notice to Warrantholder. If, while this Warrant is outstanding, the Company (i) declares a dividend or any other distribution of cash, securities or other property in respect of its Common Stock, including, without limitation, any granting of rights or warrants to subscribe for or purchase any capital stock of the Company or any subsidiary, (ii) authorizes or approves, enters into any agreement contemplating or solicits stockholder approval for any Change of Control or (iii) authorizes the voluntary dissolution, liquidation or winding up of the affairs of the Company, then the Company shall deliver to the Warrantholder a notice of such transaction at least ten (10) business days prior to the applicable record or effective date on which a person would need to hold Common Stock in order to participate in or vote with respect to such transaction; provided, however, that the failure to deliver such notice or any defect therein shall not affect the validity of the corporate action required to be described in such notice.




 


(c) Calculations.
All calculations under this Section 3 shall be made to the nearest cent or the nearest whole share, as the case may be. For purposes
of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum
of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.


 


 (d) Treatment of Warrant upon a Change of Control.




 


(1)
If, at any time while this Warrant is outstanding, the Company consummates a Change of Control, then a holder shall have the right
thereafter to receive, upon exercise of this Warrant, the same amount and kind of securities, cash or property as it would have been
entitled to receive upon the occurrence of such Change of Control if it had been, immediately prior to such Change of Control, a
holder of the number of Warrant Shares then issuable upon exercise in full of this Warrant (the “Alternate
Consideration”). The Company shall not effect any such Change of Control unless prior to or simultaneously with the
consummation thereof, any successor to the Company, surviving entity or the corporation purchasing or otherwise acquiring such
assets or other appropriate corporation or entity shall assume the obligation to deliver to the holder, such Alternate Consideration
as, in accordance with the foregoing provisions, the holder may be entitled to purchase, and the other obligations under this
Warrant.


 


(2)
As used in this Warrant, a “Change of Control” shall mean (i) a merger or consolidation of the Company with
another corporation (other than a merger effected exclusively for the purpose of changing the domicile of the Company), (ii) the
sale, assignment, transfer, conveyance or other disposal of all or substantially all of the properties or assets or all or a
majority of the outstanding voting shares of capital stock of the Company, (iii) a purchase, tender or exchange offer accepted by
the holders of a majority of the outstanding voting shares of capital stock of the Company, or (iv) a “person” or
“group” (as these terms are used for purposes of Section 13(d) and 14(d) of the Securities Exchange Act of 1934, as
amended (the “Exchange Act”)) is or shall become the “beneficial owner” (as defined in Rule 13d-3
under the Exchange Act), directly or indirectly at least a majority of the voting power of the capital stock of the
Company.


 


4.
NO FRACTIONAL SHARES. No fractional Warrant Shares or scrip representing fractional shares will be issued upon exercise of this
Warrant. In lieu of any fractional shares which would otherwise be issuable, the Company shall pay cash equal to the product of such
fraction multiplied by the Fair Market Value of one Warrant Share.


 




    	-3-



     


    

 


The
“Fair Market Value” of one share of Common Stock shall mean (x) the last reported sale price and, if there are no
sales, the last reported bid price, of the Common Stock on the business day prior to the date of exercise on the Trading Market on which
the Common Stock is then listed or quoted as reported by Bloomberg Financial Markets (or a comparable reporting service of national reputation
selected by the Company and reasonably acceptable to the holder if Bloomberg Financial Markets is not then reporting sales prices of
the Common Stock) (collectively, “Bloomberg”), (y) if the foregoing does not apply, the last sales price of the Common
Stock in the over-the-counter market on the pink sheets or bulletin board for such security as reported by Bloomberg, and, if there are
no sales, the last reported bid price of the Common Stock as reported by Bloomberg or, (z) if fair market value cannot be calculated
as of such date on either of the foregoing bases, the price determined in good faith by the Company’s Board of Directors.


 


“Trading
Market” shall mean any of the following markets or exchanges on which the Common Stock is listed or quoted for trading on the
date in question: the NYSE MKT, the NASDAQ Capital Market, the NASDAQ Global Market, the NASDAQ Global Select Market, the New York Stock
Exchange or the OTC Markets (or any successors to any of the foregoing).


 


5.
NO STOCKHOLDER RIGHTS. Until the exercise of this Warrant or any portion of this Warrant, the Warrantholder shall not have, nor
exercise, any rights as a stockholder of the Company (including without limitation the right to notification of stockholder meetings
or the right to receive any notice or other communication concerning the business and affairs of the Company) except as provided in
Section 9 below.


 


		6.	MECHANICS
                                            OF EXERCISE.



 


(a) Delivery
of Warrant Shares Upon Exercise. This Warrant may be exercised by the holder hereof, in whole or in part, by delivering to the
Company (or such other office or agency of the Company as it may designate by notice in writing to the registered Warrantholder at
the address of the Warrantholder appearing on the books of the Company) of a duly executed copy of the Notice of Exercise in the
form attached hereto as Exhibit A by facsimile or e-mail attachment and paying the Exercise Price then in effect with respect
to the number of Warrant Shares as to which the Warrant is being exercised. This Warrant shall be deemed to have been exercised
immediately prior to the close of business on the date of the delivery to the Company of the Notice of Exercise as provided above,
and the person entitled to receive the Warrant Shares issuable upon such exercise shall be treated for all purposes as the holder of
such shares of record as of the close of business on such date. Warrant Shares purchased hereunder shall be transmitted by the
Company’s transfer agent to the holder by crediting the account of the holder’s prime broker with The Depository Trust
Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in
such system and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale
of the Warrant Shares by the holder or (B) the shares are eligible for resale by the holder without volume or manner-of-sale
limitations pursuant to Rule 144, and otherwise by physical delivery to the address specified by the holder in the Notice of
Exercise by the end of the day on the date that is three (3) Trading Days from the delivery to the Company of the Notice of Exercise
and payment of the aggregate Exercise Price. The Warrant Shares shall be deemed to have been issued, and the holder or any other
person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of
the date the Warrant has been exercised, with payment to the Company of the Exercise Price and all taxes required to be paid by the
holder, if any, prior to the issuance of such shares, having been paid.

(b) Rescission
Rights. If the Company fails to cause the transfer agent to transmit to the Warrantholder the Warrant Shares pursuant to Section
6(a) by the Warrant Share Delivery Date, then the Warrantholder will have the right to rescind such exercise.


 


7.
CERTIFICATE OF ADJUSTMENT. Whenever the Exercise Price or number or type of securities issuable upon exercise of this Warrant is
adjusted, as herein provided, the Company shall, at its expense, promptly deliver to the Warrantholder a certificate of an officer
of the Company setting forth the nature of such adjustment and showing in detail the facts upon which such adjustment is
based.


 


		8.	COMPLIANCE
                                            WITH SECURITIES LAWS.



 


(a)
The Warrantholder understands that this Warrant and the Warrant Shares are characterized as “restricted securities”
under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public
offering and that under such laws and applicable regulations this Warrant and the Warrant Shares may be resold without registration
under the Securities Act only in certain limited circumstances. In this connection, the Warrantholder represents that it is familiar
with Rule 144 under the Securities Act, as presently in effect, and understands the resale limitations imposed thereby and by the
Securities Act.


 


(b)
Prior and as a condition to the sale or transfer of the Warrant Shares issuable upon exercise of this Warrant, the Warrantholder
shall furnish to the Company such certificates, representations, agreements and other information, including an opinion of counsel,
as the Company or the Company’s transfer agent reasonably may require to confirm that such sale or transfer is being made
pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act, unless such
Warrant Shares are being sold or transferred pursuant to an effective registration statement.


 


(c)
The Warrantholder acknowledges that the Company may place a restrictive legend on the Warrant Shares issuable upon exercise of this
Warrant in order to comply with applicable securities laws, in substantially the following form and substance:


 


THE
SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”), OR ANY STATE SECURITIES LAWS, AND NEITHER SUCH SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, PLEDGED, ASSIGNED
OR OTHERWISE TRANSFERRED UNLESS (1) A REGISTRATION STATEMENT WITH RESPECT THERETO IS EFFECTIVE UNDER THE SECURITIES ACT AND ANY APPLICABLE
STATE SECURITIES LAWS, OR (2) AN EXEMPTION FROM SUCH REGISTRATION EXISTS AND THE COMPANY RECEIVES AN OPINION OF COUNSEL, WHICH COUNSEL
AND OPINION ARE REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED, ASSIGNED OR TRANSFERRED IN
THE MANNER CONTEMPLATED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR APPLICABLE STATE SECURITIES LAWS. HEDGING
TRANSACTIONS INVOLVING THESE SECURITIES MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH.


 


9.
REPLACEMENT OF WARRANTS. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation
of this Warrant and, in the case of any such loss, theft or destruction of this Warrant, on delivery of an indemnity agreement
reasonably satisfactory in form and amount to the Company or, in the case of any such mutilation, on surrender and cancellation of
such Warrant, the Company at its expense will execute and deliver, in lieu thereof, a new Warrant of like tenor.


 




    	-5-



     


    

 


10.
NO IMPAIRMENT. Except to the extent as may be waived by the holder of this Warrant, the Company will not, by amendment of its
charter or through a Change of Control, dissolution, sale of assets or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all
such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the
Warrantholder against impairment.


 


11.
TRADING DAYS. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein
shall be other than a day on which the Common Stock is traded on the Trading Market, then such action may be taken or such right may
be exercised on the next succeeding day on which the Common Stock is so traded.


 


		12.	TRANSFERS;
                                            EXCHANGES.



 


(a)
Except as provided hereinafter in this Section, neither this Warrant nor any right or obligation hereunder may be assigned in whole
or in part by the Warrantholder. Subject to compliance with applicable federal and state securities laws and Section 8
hereof, this Warrant may be transferred by the Warrantholder in a Permitted Transfer (as defined below) with respect to any or all
of the Warrant Shares purchasable hereunder (a “Permitted Transfer”). For a transfer of this Warrant as an
entirety by the Warrantholder, upon surrender of this Warrant to the Company, together with the Notice of Assignment in the form
attached hereto as Exhibit B duly completed and executed on behalf of the Warrantholder, the Company shall issue a new
Warrant of the same denomination to the assignee. For a transfer of this Warrant with respect to a portion of the Warrant Shares
purchasable hereunder, upon surrender of this Warrant to the Company, together with the Notice of Assignment in the form attached
hereto as Exhibit B duly completed and executed on behalf of the Warrantholder, the Company shall issue a new Warrant to the
assignee, in such denomination as shall be requested by the Warrantholder, and shall issue to the Warrantholder a new Warrant
covering the number of shares in respect of which this Warrant shall not have been transferred.


 


“Permitted
Transfer” shall mean:


 


(i)
if the Warrantholder is a natural person, any transfers made by the Warrantholder (A) to any member of the Immediate Family of the
Warrantholder or to a trust the direct or indirect beneficiaries of which are exclusively the Warrantholder or members of the
Warrantholder’s Immediate Family, or (B) by bona fide gift, will or intestacy to members of the Warrantholder’s
Immediate Family;


 


 (ii) any transfer to a charitable organization not for value;




 


(iii)
if the Warrantholder is a corporation, partnership, limited liability company or other business entity, any transfer made by the
Warrantholder:


 


(A)
in connection with the sale or other bona fide transfer in a single transaction of all or substantially all of the
Warrantholder’s capital stock, partnership interests, membership interests or other similar equity interests, as the case may
be, or all or substantially all of the Warrantholder’s assets, in any such case not undertaken for the purpose of avoiding the
restrictions imposed by this Agreement,


 




    	-6-



     


    

 


(B)
to another corporation, partnership, limited liability company or other business entity so long as the transferee is an Affiliate of
the Warrantholder,


 


 (C) to any Affiliate of the Warrantholder, or




 


(D)
to any investment fund or other entity that controls or manages the Warrantholder (including, for the avoidance of doubt, a fund
managed by the same manager or managing member or general partner or management company or by an entity controlling, controlled by,
or under common control with such manager or managing member or general partner or management company as the Warrantholder) if such
transfer is not for value;


 


(iv)
if the Warrantholder is a trust, any transfer to a trustor or beneficiary of the trust if such transfer is not for value;
or


 


(v)
any transfer pursuant to a court order or by operation of law, including pursuant to a domestic order or a negotiated divorce
settlement.


 


“Immediate
Family” means mother, father, son, daughter or sibling or relation by domestic partnership, marriage or adoption.


 


“Affiliate”
means, with respect to any person, any other person that, directly or indirectly through one or more intermediaries, controls, is controlled
by or is under common control with such person, and any officers, employees or partners of the Warrantholder.


 


(b)
Upon any Permitted Transfer, this Warrant is exchangeable, without expense, at the option of the Warrantholder, upon presentation
and surrender hereof to the Company for other warrants of different denominations entitling the holder thereof to purchase in the
aggregate the same number of shares of Common Stock purchasable hereunder. This Warrant may be divided or combined with other
warrants that carry the same rights upon presentation hereof at the principal office of the Company together with a written notice
specifying the denominations in which new warrants are to be issued to the Warrantholder and signed by the Warrantholder hereof. The
term “Warrants” as used herein includes any warrants into which this Warrant may be divided or
exchanged.


 


13.
AUTHORIZED SHARES. The Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and
unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any
purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority
to its officers who are charged with the duty of issuing the necessary Warrant Shares upon the exercise of the purchase rights under
this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued
as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which
the Common Stock may be quoted or listed. The Company covenants that all Warrant Shares which may be issued upon the exercise of the
purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for
such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all
taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer
occurring contemporaneously with such issue).


 


14.
NO STOCK RIGHTS. No holder of this Warrant, as such, shall be entitled to vote or be deemed the holder of any other securities of
the Company that may at any time be issuable on the exercise hereof, nor shall anything contained herein be construed to confer upon
the holder of this Warrant, as such, the rights of a stockholder of the Company or the right to vote for the election of directors
or upon any matter submitted to stockholders at any meeting thereof, or give or withhold consent to any corporate action or to
receive notice of meetings or other actions affecting stockholders (except as provided herein), or to receive dividends or
subscription rights or otherwise (except as provided herein).

FINAL


 


CERTIFICATE
OF DESIGNATIONS,


 


PREFERENCES AND RIGHTS


 


of


 


SERIES
A CONVERTIBLE PREFERRED STOCK


 


of


 


SHUTTLE
PHARMACEUTICALS HOLDINGS, INC.


 


Shuttle
Pharmaceuticals Holdings, Inc., a corporation organized and existing under the laws of the State of Delaware (the “Corporation”),
hereby certifies that the Board of Directors of the Corporation (the “Board of Directors” or the “Board”),
pursuant to authority of the Board of Directors as required by applicable law, and in accordance with the provisions of its certificate
of incorporation and by-laws, has authorized and hereby authorizes a series of the Corporation’s previously authorized Preferred
Stock, par value $0.0001 per share (the “Preferred Stock”), and hereby states the designation and number of shares,
and fixes the voting powers, designations, preferences, limitations, restrictions and relative rights thereof, as follows:


 


Capitalized
terms used and not otherwise immediately defined are defined in Section 10 below.


 


1.
Designation and Amount. The series of Preferred Stock shall be designated as the “8.5% Series A Convertible Preferred Stock”
(the “Series A Preferred Stock”) and the number of shares so designated shall be 10,000.


 


2.
Stated Value; Dividends.


 


a.
Par Value and Stated Value. The par value of each issued share of Series A Preferred Stock shall be $0.00001 per share, and the
stated value of each issued share of Series A Preferred Stock shall be deemed to be $1,000 (the “Stated Value”).


 


b.
Dividends. Before any dividends shall be paid or set aside for payment on any Junior Security of the Corporation, each Holder
of the Series A Preferred Stock shall be entitled to receive dividends, in the manner provided herein, payable on the Stated Value of
the Series A Preferred Stock at a rate of 8.5% per annum, which shall be cumulative and be due and payable, at the Company’s option,
in cash or in shares of Common Stock, or a combination thereof, on the Conversion Date (as defined below) or in cash on the Redemption
Date (as defined below), in each case as provided below (the applicable date of payment, a “Dividend Date”). Such
dividends shall accrue from the date of issue of each share of Series A Preferred Stock, whether or not declared, through the Dividend
Date. If a Dividend Date is not a business day, then the dividend shall be due and payable on the business day immediately following
such Dividend Date.


 


Dividends
shall be payable to Holders of record of the Series A Preferred Stock as they appear on the stock books of the Corporation on the Dividend
Date.


 




    	 



    	 



    

 





Except
as provided in the following paragraph, if the dividend on the Series A Preferred Stock shall not have been paid or set apart in full
for the Series A Preferred Stock when payable, the aggregate deficiency shall be cumulative and shall be fully paid or set apart for
payment before any dividends shall be paid upon or set apart for, or any other distributions paid made on, or any payments made on account
of the purchase, redemption or retirement of, the Common Stock or any other Junior Security. When dividends are not paid in full upon
the shares or fractions of a share of Series A Preferred Stock and any shares pari passu with the Series A Preferred Stock, all
dividends declared upon this series and any other shares pari passu with the Series A Preferred Stock shall be declared, pro rata,
so that the amount of dividends declared per share or fraction of a share on this Series A Preferred Stock and such other shares pari passu with the Series A Preferred Stock shall in all cases bear to each other the same rates that accrued dividends per share on
the shares of Series A Preferred Stock and such other shares pari passu with the Series A Preferred Stock bear to each other.


 


3.
Voting.


 


a.
Voting Rights. Except as provided in Section 3(b) below or as required by law, Holders of the shares of Series A Preferred
Stock shall not have the right to vote on any matter as to which shareholders are required or permitted to vote. Only in the case of
a vote to be taken pursuant to Section 3(b) below or when required by law, each Holder of the shares of Series A Preferred Stock
shall have the right to the number of votes equal to the number of Conversion Shares then issuable upon conversion of the Series A Preferred
Stock held by such Holder.


 


b.
Limitations on Corporate Actions. Notwithstanding anything to the contrary in Section 3(a) above, as long as any shares
of Series A Preferred Stock are outstanding, the Corporation shall not, without the written consent or affirmative vote of the Holders
of no less than sixty-five percent (65%) of the then-outstanding shares of Series A Preferred Stock, consenting or voting (as the case
may be) as a separate class from the Common Stock, either directly or by amendment, merger, consolidation or otherwise:


 


(i)
amend its certificate of incorporation in any manner that adversely affects the rights of the Holders;


 


(ii)
alter or change adversely the voting or other powers, preferences, rights, privileges, or restrictions of the Series A Preferred Stock
contained herein or alter or amend this Certificate of Designations;


 


(iii)
redeem, purchase or otherwise acquire directly or indirectly any Junior Securities or any shares pari passu with the Series A
Preferred Stock;


 


(iv)
directly or indirectly pay or declare any dividend or make any distribution in respect of, any Junior Securities, or set aside any monies
for the purchase or redemption (through a sinking fund or otherwise) of any Junior Securities or any shares pari passu with the
Series A Preferred Stock;


 


(v)
authorize or create any class of stock ranking as to dividends, redemption or distribution of assets upon a Liquidation (as defined in
Section 4 below) senior to the Series A Preferred Stock; or


 


(vi)
enter into any agreement with respect to any of the foregoing.


 




    	2



    	 



    




 


4.
Liquidation, Dissolution, or Winding-Down.


 


a.
Payments to Holders of Series A Preferred Stock. Upon any liquidation, dissolution or winding-down of the Corporation, whether
voluntary or involuntary (a “Liquidation”), the Holders of the shares of Series A Preferred Stock shall be paid in
cash, before any payment shall be paid to the holders of Common Stock, or any other Junior Securities, an amount for each share of Series
A Preferred Stock held by such Holder equal to 100% of the Stated Value thereof plus 100% of any dividends accrued but unpaid thereon
(such applicable amount payable with respect to all shares of Series A Preferred Stock in the aggregate being referred to as the “Aggregate
Series A Liquidation Preference Payment”). If, upon such liquidation, dissolution or winding-up of the Corporation, whether
voluntary or involuntary, the assets available to be distributed among the Holders of shares of Series A Preferred Stock shall be insufficient
to permit payment to the Holders of Series A Preferred Stock of an aggregate amount equal to the Aggregate Series A Liquidation Preference
Payment, then the Holders of shares of Series A Preferred Stock shall share ratably in any distribution of the assets available for distribution
in proportion to the respective amounts which would otherwise be payable in respect of the shares held by them upon such distribution
if all amounts payable on or with respect to such shares were paid in full.


 


b.
Payments to Holders of Junior Securities. After the payment of all preferential amounts required to be paid to the Holders of
the Series A Preferred Stock and any other class or series of stock of the Corporation ranking on liquidation senior to or on a parity
with the Series A Preferred Stock, the holders of Junior Securities then outstanding shall be entitled to receive the remaining assets
of the Corporation available for distribution to its stockholders as otherwise set forth in the Corporation’s certificate of incorporation.


 


5.
Automatic Conversion. Upon the earlier of (a) the closing of the sale of shares of Common Stock to the public at a price per share
of at least $13.88 (subject to adjustment as provided in Section 6 below) (the “Minimum IPO Price”), in a firm commitment
underwritten public offering pursuant to an effective registration statement under the Securities Act, resulting in gross proceeds (before
underwriters’ discounts, commissions and expenses) to the Company of an amount at least equal to the difference between (i) $25,000,000
and (ii) the gross proceeds (before underwriters’ discounts, commissions and expenses) to the Company of the sale by the Company
of the total number of shares of Series A Preferred Stock that are sold (a “Qualified IPO”), or (b) listing of the
Common Stock on the New York Stock Exchange, NYSE American, Nasdaq Global Select Market, Nasdaq Global Market or Nasdaq Capital Market
(or any successor thereto), all outstanding shares of Series A Preferred Stock shall automatically, and without the payment of additional
consideration by the Holder thereof, and without any notice to the Holder thereof or any further action by any Person, be converted into
such number of fully paid and non-assessable shares of Common Stock as is determined by dividing the Stated Value per share plus accrued
and unpaid dividends thereon by the Conversion Price then in effect.


 


The
“Conversion Price” per share of Common Stock shall be equal to (A) in the case of conversion pursuant to clause 5(a)
above, 90% of the gross public offering price per share of Common Stock (before deducting underwriters’ discount, commissions and
expenses) of the Qualified IPO, or (B) in the case of conversion pursuant to clause 5(b) above, $12.49 (subject to adjustment as provided
in Section 6 below) (the “Listing Conversion Price”).


 




    	3



    	 



    




 


b.
Fractional Shares. No fractional shares of Common Stock shall be issued upon conversion of the Series A Preferred Stock. In lieu
of any fractional shares to which the Holder would otherwise be entitled, the Corporation shall pay cash equal to such fraction multiplied
by the fair market value of a share of Common Stock as determined in good faith by the Board of Directors, or round-up to the next whole
number of shares, at the Corporation’s option. Whether or not fractional shares would be issuable upon such conversion shall be
determined on the basis of the total number of shares of Series A Preferred Stock of the Holder that at the time are being converted
into Common Stock and the aggregate number of shares of Common Stock issuable upon such conversion.


 


c.
Mechanics of Conversion.


 


i.
Issuance of Common Stock upon Conversion. Not later than five (5) Trading Days after the Conversion Date (the “Share
Delivery Date”), the Corporation shall issue, or cause to be issued, to each converting Holder the number of shares of Common
Stock being acquired upon the conversion of shares of Series A Preferred Stock. All shares of Series A Preferred Stock which shall have
been converted as herein provided shall no longer be deemed to be outstanding, and all rights with respect to such shares shall immediately
cease and terminate at the Share Delivery Date, except only the right of the Holders thereof to receive shares of Common Stock in exchange
therefor as provided herein, and to receive payment in lieu of any fraction of a share otherwise issuable upon such conversion as provided
herein.


 


ii.
Obligation Absolute; Damages. The Corporation’s obligation to issue and deliver the Conversion Shares upon conversion of
Series A Preferred Stock in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by
a Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person
or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach
by such Holder or any other Person of any obligation to the Corporation; provided, however, that such delivery shall not
operate as a waiver by the Corporation of any such action that the Corporation may have against such Holder.


 


e.
Reservation of Shares Issuable upon Conversion. The Corporation covenants, so long as the Shares of Series A Preferred Stock are
outstanding, that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock for the sole
purpose of issuance upon conversion of the Series A Preferred Stock, free from preemptive rights or any other actual contingent purchase
rights of Persons other than the Holders of the Series A Preferred Stock, not less than such aggregate number of shares of the Common
Stock as shall be issuable upon the conversion of all outstanding shares of Series A Preferred Stock. The Corporation covenants that
all shares of Common Stock that shall be so issuable shall, upon issue in accordance with the terms herein, be duly authorized, validly
issued, fully paid and nonassessable.


 




    	4



    	 



    

 





6.
Certain Adjustments.


 


a.
Subdivision or Combination of Stock. If, at any time while the Series A Preferred Stock is outstanding, the Corporation shall
subdivide (whether by way of stock dividend, stock split or otherwise) its outstanding shares of Common Stock into a greater number of
shares, each of the Minimum IPO Price and the Listing Conversion Price in effect immediately prior to such subdivision shall be proportionately
reduced, and conversely, in case the outstanding shares of Common Stock of the Corporation shall be combined (whether by way of stock
combination, reverse stock split or otherwise) into a smaller number of shares, each of the Minimum IPO Price and the Listing Conversion
Price in effect immediately prior to such combination shall be proportionately increased. Each of the Minimum IPO Price and the Listing
Conversion Price, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described
in this Section 6(a).


 


b.
Dividends in Stock, Property, Reclassification. If, at any time while the Series A Preferred Stock is outstanding, the holders
of Common Stock (or any shares of stock or other securities at the time receivable upon the conversion of the Series A Preferred Stock)
shall have received or become entitled to receive, without payment therefore:


 


(i)
any Common Stock Equivalents, or any rights or options to subscribe for, purchase or otherwise acquire any of the foregoing by way of
dividend or other distribution, or


 


(ii)
additional stock or other securities or property (other than cash in respect of which shall be covered by the terms of Section 3(c) above)
by way of spin-off, split- up, reclassification, combination of shares or similar corporate rearrangement (other than shares of Common
Stock issued as a stock split or adjustments in respect of which shall be covered by the terms of Section 6(a) above),


 


then
and in each such case, each of the Minimum IPO Price and the Listing Conversion Price shall be adjusted proportionately, and the Holder
hereof shall, upon the conversion of the Series A Preferred Stock, be entitled to receive, in addition to the number of shares of Common
Stock receivable thereupon, and without payment of any additional consideration therefor, the amount of stock and other securities and
property that such Holder would hold on the date of such exercise had such Holder been the holder of record of such Common Stock as of
the date on which holders of Common Stock received or became entitled to receive such shares or all other additional stock and other
securities and property. Each of the Minimum IPO Price and the Listing Conversion Price, as so adjusted, shall be readjusted in the same

c.
Reorganization, Reclassification, Consolidation, Merger or Sale. At any time while the Series A Preferred Stock is outstanding,
if any recapitalization, reclassification or reorganization of the capital stock of the Corporation, or any consolidation or merger of
the Corporation with another corporation, or the sale of all or substantially all of its assets or other transaction shall be effected
in such a way that holders of Common Stock shall be entitled to receive stock, securities or other assets or property (an “Organic
Change”), then lawful and adequate provisions shall be made by the Corporation whereby the Holders shall thereafter have the
right to purchase and receive (in lieu of the shares of the Common Stock of the Corporation immediately theretofore purchasable and receivable
upon the conversion of the Series A Preferred Stock) such shares of stock, securities or other assets or property as may be issued or
payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such
stock immediately theretofore purchasable and receivable assuming the full conversion of the Series A Preferred Stock. In the event of
any Organic Change, appropriate provision shall be made by the Corporation with respect to the rights and interests of the Holders to
the end that the provisions hereof (including, without limitation, provisions for adjustments of the Minimum IPO Price and the Listing
Conversion Price) shall thereafter be applicable, in relation to any shares of stock, securities or assets thereafter deliverable upon
the conversion thereof. To the extent necessary to effect the foregoing provisions, the successor corporation (if other than the Corporation)
resulting from such consolidation or merger or the corporation purchasing such assets shall assume by written instrument executed and
mailed or delivered to each Holder at the last address of such Holder appearing on the books of the Corporation, the obligation to deliver
to such Holder such shares of stock, securities or assets as, in accordance with the foregoing provisions, such Holder may be entitled
to purchase. If there is an Organic Change, then the Corporation shall cause to be mailed to each Holder at its last address as it shall
appear on the books and records of the Corporation, at least ten (10) calendar days before the effective date of the Organic Change,
a notice stating the date on which such Organic Change is expected to become effective or close, and the date as of which it is expected
that holders of the Common Stock of record shall be entitled to exchange their shares for securities, cash, or other property delivered
upon such Organic Change; provided, that the failure to mail such notice or any defect therein or in the mailing thereof shall
not affect the validity of the corporate action required to be specified in such notice. Each Holder is entitled to convert such Holder’s
Series A Preferred Stock during the 10-day period commencing on the date of such notice to the effective date of the event triggering
such notice. In any event, the successor corporation (if other than the Corporation) resulting from such consolidation or merger or the
corporation purchasing such assets shall be deemed to assume such obligation to deliver to such Holder such shares of stock, securities
or assets even in the absence of a written instrument assuming such obligation to the extent such assumption occurs by operation of law.


 


d.
Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment pursuant to this Section 6, the Corporation
at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each Holder
a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment
is based. The Corporation shall promptly furnish or cause to be furnished to such Holder a like certificate setting forth: (i) such adjustments
and readjustments; and (ii) the number of shares and the amount, if any, of other property which at the time would be received upon the
conversion of the Series A Preferred Stock.


 


7.
Optional Redemption. Shares of the Series A Preferred Stock shall be redeemable in cash, in whole or in part, at the option of
the Corporation, by resolution of its Board of Directors, at any time, subject to the Redemption Notice requirements below, at a price
per share equal to one hundred percent (100%) of the Stated Value plus one hundred percent (100%) of the amount of accrued but unpaid
dividends thereon. The Corporation shall provide written notice to all Holders of record of shares of Series A Preferred Stock specifying
the time (the “Redemption Date”) and place of such redemption (the “Redemption Notice”), at their
respective addresses as the same shall appear on the stock books of the Corporation, but no failure on the part of the shareholder to
receive such notice and no defect in the wording of the notice shall affect the validity of the proceedings adopted with respect to the
redemption of any such shares. The Redemption Notice shall be given not less than thirty (30) days prior to the Redemption Date.

8.
Status of Series A Preferred Stock Converted or Reacquired. Shares of Series A Preferred Stock converted into Common Stock or
reacquired by the Corporation in any manner, including shares purchased or redeemed, shall (upon compliance with any applicable provisions
of the laws of the State of Delaware) have the status of authorized and unissued shares of the class of Preferred Stock undesignated
as to series, and may be redesignated and reissued as part of any series of the Preferred Stock.


 


9.
Calculations. In the case of a dispute as to the determination of the Conversion Price, or the arithmetic calculation of the number
of shares of Common stock to be issued upon any conversion of Series A Preferred Stock or of the amount of accrued dividends on the Series
A Preferred Stock (a “Disputed Amount”), the Corporation or the Holder (as the case may be) shall submit the disputed
determinations or arithmetic calculations (as the case may be) via facsimile or e-mail (i) within two (2) Trading Days after receipt
of the applicable notice giving rise to such dispute to the Corporation or the Holder (as the case may be), or (ii) if no notice gave
rise to such dispute, at any time after the Holder learned of the circumstances giving rise to such dispute. If the Holder and the Corporation
are unable to agree upon such determination or calculation of the Disputed Amount within three Trading Days of such disputed determination
or arithmetic calculation being submitted, then the Corporation shall within five (5) Business Days, submit in writing (a) the disputed
determination of the Conversion Price to an independent, reputable investment bank selected by the Corporation and approved by the Holder,
or (b) the disputed arithmetic calculation of the number of shares of Common stock to be issued upon conversion or the amount of accrued
dividends to the Corporation’s independent certified public accountant. The Corporation shall cause at its expense the investment
bank or the accountant, as the case may be, to perform the determinations or calculations and notify the Corporation and the Holder of
the results no later than ten (10) Trading Days from the time it receives the disputed determinations or calculations; provided that,
if such disputed determination or arithmetic calculation being submitted by the Holder is determined to be incorrect, then the expense
of the investment bank or the accountant shall be the responsibility of the Holder. Such investment bank’s or accountant’s
determination or calculation, as the case may be, shall be final, binding and conclusive upon the parties thereto.

3.
Registration.


 





(a)
IPO Registration Statement. If, following the date hereof, the Company shall determine to register for sale for cash any of its
Common Stock through an IPO (the “IPO Registration Statement”), for its own account or for the account of others (other
than the Holders), other than (i) a registration relating solely to employee benefit plans or securities issued or issuable to employees,

solely to a Securities Act Rule 145 transaction or a registration on Form S-4 (or its then equivalent form) in connection with a merger,
acquisition, divestiture, reorganization or similar event, or (iii) a transaction relating solely to the sale of debt or convertible
debt instruments, then the Company shall promptly give to each Holder written notice thereof (the “Registration Rights Notice”)
that the Company intends to include all of the Registerable Securities in the IPO Registration Statement. Nonetheless, the Company may,
without the consent of such Holders, remove some or all of the Registrable Securities from the IPO Registration Statement if the managing
underwriter or the Company determines that marketing factors require a limitation on the number of shares of Common Stock or the amount
of other securities to be included in the IPO Registration Statement or if the staff of the Commission (the “Commission Staff”)
otherwise requires such removal. The Company shall then use its commercially reasonable efforts to cause such IPO Registration Statement
to be declared effective, and the IPO to be closed, within twelve (12) months following the Effective Date;


 


(b)
Resale Registration Statement. If an IPO Registration Statement has not been declared effective with respect to all of the Registrable
Shares by the first anniversary of the Effective Date, then, within 60 days following such anniversary date, the Company will prepare
and file with the Commission a Resale Registration Statement with respect to the Registrable Shares not included in an effective IPO
Registration Statement. The Company will then use its commercially reasonable efforts to cause such Resale Registration Statement to
be declared effective (the “Registration Effectiveness Date”) within 120 days after the initial filing of the Resale
Registration Statement. Notwithstanding the foregoing, in the event that the Commission Staff should limit the number of Registrable
Securities that may be sold pursuant to the Resale Registration Statement, the Company may remove from the Resale Registration Statement
such number of Registrable Securities as specified by the Staff first from the shares of Common Stock issued or issuable upon
exercise of the Placement Agent Warrants, if any, on a pro rata basis among the Holders thereof, and second from the other Registrable
Securities, on a pro rata basis among the Holders thereof (such Registrable Securities, the “Reduction Securities”).
In such event, the Company shall give the Holders prompt notice of the number of Registrable Securities excluded therefrom. The Company
shall use its commercially reasonable efforts at the first opportunity permitted by the Commission to register for resale the Reduction
Securities (on a pro rata basis among the Holders of such Reduction Securities, as needed) using one or more registration statement.


 




    	5



    	 



    




 


(c)
Effectiveness Period. The Company shall use its commercially reasonable efforts to keep such Registration Statement(s) effective
for a period of two (2) years commencing on the SEC Effective Date or for such shorter period ending on the earlier to occur of (i) the
date on which all Registrable Securities have been transferred other than to a Permitted Assignee and (ii) the date as of which all of
the Holders may sell all of the Registrable Securities without restriction pursuant to Rule 144 (including, without limitation, volume
restrictions) and without the need for current public information required by Rule 144(c)(1) or Rule 144(i)(2), if applicable (the “Effectiveness
Period”); provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance
pursuant to this Section, or keep such registration effective pursuant to the terms hereunder, in any particular jurisdiction in which
the Company would be required to qualify to do business as a foreign corporation or as a dealer in securities under the securities laws
of such jurisdiction or to execute a general consent to service of process in effecting such registration, qualification or compliance,
in each case, where it has not already done so. Notwithstanding the foregoing, the Company shall be entitled to suspend the effectiveness
of such Registration Statement at any time prior to the expiration of the Effectiveness Period for the reasons and time periods as may
be required during a Blackout Period.


 


4.
Registration Procedures. The Company will keep each Holder reasonably advised as to the filing and effectiveness of the IPO Registration
Statement and the Resale Registration Statement, as applicable. At its expense, solely with respect to such Registration Statement, the
Company will:


 


(a)
prepare and file with the Commission the IPO Registration Statement, in accordance with Section (a) hereof covering the resale of the
Registrable Securities, and, if so filed, use its commercially reasonable efforts to cause such IPO Registration Statement to become
effective;


 


(b)
prepare and file the Resale Registration Statement, if necessary, in accordance with Section 3(b), and use its commercially reasonable
efforts to cause such Resale Registration Statement to be declared effective no later than 120 days after the initial filing of the Resale
Registration Statement and to remain effective for the Effectiveness Period;


 


(c)
not name any Holder in the Registration Statement as an underwriter without that Holder’s prior written consent;

Statement (including each preliminary prospectus and any other prospectus filed under Rule 424 of the Securities Act) as such Holders
may reasonably request, in conformity with the requirements of the Securities Act, and (iii) such other documents as such Holder may
reasonably require to consummate the disposition of the Registrable Securities owned by such Holder, but only during the Effectiveness
Period; provided that the Company shall have no obligation to furnish any document pursuant to this clause that is available on the Commission’s

    	6



    	 



    




 


(g)
use its commercially reasonable efforts to register or qualify such registration under such other applicable securities laws of such
jurisdictions within the United States as any Holder of Registrable Securities covered by the applicable Registration Statement reasonably
requests and as may be necessary for the marketability of the Registrable Securities (such request to be made by the time the applicable
Registration Statement is deemed effective by the Commission) and do any and all other acts and things necessary to enable such Holder
to consummate the disposition in such jurisdictions of the Registrable Securities owned by such Holder; provided, that the Company
shall not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify
but for this paragraph, (ii) subject itself to taxation in any such jurisdiction, or (iii) consent to general service of process in any
such jurisdiction;


 


(h)
as promptly as practicable after becoming aware of an event the disposition of which requires the delivery of a prospectus relating thereto
under the Securities Act, notify each Holder of Registrable Securities of the happening of any event, which comes to the Company’s
attention, that will after the occurrence of such event cause the prospectus included in such Registration Statement, if not amended
or supplemented, to contain an untrue statement of a material fact or an omission to state a material fact required to be stated therein
or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading and the Company
shall promptly thereafter prepare and furnish to such Holder a supplement or amendment to such prospectus (or prepare and file appropriate
reports under the Exchange Act) so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall
not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make
the statements therein, in the light of the circumstances under which they were made, not misleading, unless suspension of the use of
such prospectus otherwise is authorized herein or in the event of a Blackout Period, in which case no supplement or amendment need be
furnished (or Exchange Act filing made) until the termination of such suspension or Blackout Period; provided that any and all information
provided to the Holder pursuant to such notification shall remain confidential to each Holder until such information otherwise becomes
public, unless disclosure by a Holder is required by law;


 


(i)
comply, and continue to comply during the Effectiveness Period, in all material respects with the Securities Act and the Exchange Act
and with all applicable rules and regulations of the Commission with respect to the disposition of all securities covered by such Registration
Statement;


 




    	7



    	 



    




 


(j)
as promptly as practicable after becoming aware of such event, notify each Holder of Registrable Securities being offered or sold pursuant
to the applicable Registration Statement of the issuance by the Commission of any stop order or other suspension of effectiveness of
the Registration Statement;


 


(k)
use its commercially reasonable efforts to cause all the Registrable Securities covered by the Registration Statement to be listed on
a Qualified Exchange;


 


(l)
provide a transfer agent and registrar, which may be a single entity, for the shares of Common Stock at all times;


 


(m)
cooperate with the Holders of Registrable Securities being offered pursuant to the IPO Registration Statement or the Resale Registration
Statement, as applicable, to issue and deliver, or cause its transfer agent to issue and deliver, certificates representing Registrable
Securities to be offered pursuant to the applicable Registration Statement within a reasonable time after the delivery of certificates
representing the Registrable Securities to the transfer agent or the Company, as applicable, and enable such certificates to be in such
denominations or amounts as the Holders may reasonably request and registered in such names as the Holders may request;


 


(n)
during the Effectiveness Period, refrain from bidding for or purchasing any Common Stock or any right to purchase Common Stock or attempting
to induce any person to purchase any such security or right if such bid, purchase or attempt would in any way limit the right of the
Holders to sell Registrable Securities by reason of the limitations set forth in Regulation M of the Exchange Act; and


 


(o)
take all other commercially reasonable actions necessary to expedite and facilitate the disposition by the Holders of the Registrable
Securities pursuant to the applicable Registration Statement during the term of this Agreement; provided, however, the
Company is not obligated under this clause (o) to expend any of the Company’s funds, other than the costs and expenses specifically
required under Section 6 of this Agreement.


 


5.
Obligations of the Holders.


 


(a)
Each Holder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3(h)
hereof or of the commencement of a Blackout Period, such Holder shall discontinue the disposition of Registrable Securities included
in the Registration Statement until such Holder’s receipt of the copies of the supplemented or amended prospectus contemplated
by Section 3(h) hereof or notice of the end of the Blackout Period, and, if so directed by the Company, such Holder shall deliver to
the Company (at the Company’s expense) all copies (including, without limitation, any and all drafts), other than permanent file
copies, then in such Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt
of such notice.


 




    	8



    	 



    

 


(b)
The Holders of the Registrable Securities shall provide such information as may reasonably be requested by the Company, or the managing
underwriter, if any, in connection with the preparation of any registration statement, including amendments and supplements thereto,
in order to effect the registration of any Registrable Securities under the Securities Act pursuant to Section 3(a) and/or 3(b) of this
Agreement and in connection with the Company’s obligation to comply with federal and applicable state securities laws, including
a completed questionnaire in the form attached to this Agreement as Annex A (a “Selling Securityholder Questionnaire”)
or any update thereto not later than three (3) Business Days following a request therefor from the Company.


 


(c)
Each Holder, by its acceptance of the Registrable Securities, agrees to cooperate with the Company as reasonably requested by the Company
in connection with the preparation and filing of any Registration Statement hereunder, unless such Holder has notified the Company in
writing of its election to exclude all of its Registrable Securities from such Registration Statement.


 


6.
Registration Expenses. The Company shall pay all expenses in connection with any registration obligation provided herein, including,
without limitation, all registration, filing, stock exchange fees, printing expenses, all fees and expenses of complying with applicable
securities laws, and the fees and disbursements of counsel for the Company (but not for the Holders)and of the Company’s independent
accountants; provided, that, in any underwritten registration, the Company shall have no obligation to pay any underwriting discounts,
selling commissions or transfer taxes attributable to the Registrable Securities being sold by the Holders thereof, which underwriting
discounts, selling commissions and transfer taxes shall be borne by such Holders. Additionally, in an underwritten offering, all selling
stockholders and the Company shall bear the expenses of the underwriter pro rata in proportion to the respective amount of shares each
is selling in such offering. Except as provided in this Section 6 and Section 8 of this Agreement, the Company shall not be responsible
for the expenses of any attorney or other advisor employed by a Holder.


 


7.
Assignment of Rights. No Holder may assign its rights under this Agreement to any party without the prior written consent of the
Company; provided, however, that any Holder may assign its rights under this Agreement without such consent to a Permitted
Assignee as long as (a) such transfer or assignment is effected in accordance with applicable securities laws; (b) such transferee or
assignee agrees in writing to become bound by and subject to the terms of this Agreement; and (c) such Holder notifies the Company in
writing of such transfer or assignment, stating the name and address of the transferee or assignee and identifying the Registrable Securities
with respect to which such rights are being transferred or assigned. The Company may assign this Agreement or any rights or obligations
hereunder without the prior written consent of any other party hereto.

8.
Indemnification.


 


(a)
In the event of the offer and sale of Registrable Securities under the Securities Act, the Company shall, and hereby does, indemnify
and hold harmless, to the fullest extent permitted by law, each Holder, its directors, officers, partners, and each other person, if
any, who controls or is under common control with such Holder within the meaning of Section 15 of the Securities Act, against any losses,
claims, damages or liabilities, joint or several, and expenses to which the Holder or any such director, officer, partner or controlling
person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages, liabilities or expenses (or
actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement of any
material fact contained in any registration statement prepared and filed by the Company under which Registrable Securities were registered
under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement
thereto, or any omission to state therein a material fact required to be stated or necessary to make the statements therein, in light
of the circumstances in which they were made, not misleading, and the Company shall reimburse the Holder, and each such director, officer,
partner and controlling person for any legal or any other expenses reasonably incurred by them in connection with investigating, defending
or settling any such loss, claim, damage, liability, action or proceeding; provided, however, that the indemnity obligation
of the Company under this Section 8(a) to any Holder shall in no event exceed the net proceeds from the Offering received by the Company
from such Holder (or Holder’s predecessor-in-interest); and provided further, that the Company shall not be liable in any
such case (i) to the extent that any such loss, claim, damage, or liability (or action or proceeding in respect thereof) or expense arises
out of or is based upon (x) an untrue statement in or omission from such registration statement, any such preliminary prospectus, final
prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity with written information furnished by a Holder
or its representative to the Company for use in the preparation thereof or (y) the failure of a Holder to comply with the covenants and
agreements contained in Section 5 hereof respecting the sale of Registrable Securities; or (ii) if the person asserting any such loss,
claim, damage or liability (or action or proceeding in respect thereof) who purchased the Registrable Securities that are the subject
thereof did not receive a copy of an amended preliminary or final prospectus or the final prospectus (or the final prospectus as amended
or supplemented) at or prior to the written confirmation of the sale of such Registrable Securities to such person because of the failure
of such Holder to so provide such amended preliminary or final prospectus and the untrue statement or omission of a material fact made
in such preliminary or final prospectus was corrected in the amended preliminary or final prospectus (or the final prospectus as amended
or supplemented). Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Holders,
or any such director, officer, partner or controlling person and shall survive the transfer of such shares by the Holder.


 




    	10



    	 



    




 


(b)
As a condition to including Registrable Securities in any registration statement filed pursuant to this Agreement, each Holder agrees
to be bound by the terms of this Section 8 and to indemnify and hold harmless, to the fullest extent permitted by law, the Company, each
of its directors, officers, partners, legal counsel and accountants and each underwriter, if any, and each other person, if any, who
controls the Company within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities, joint
or several, to which the Company or any such director or officer or controlling person may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect
thereof) arise out of or are based upon any untrue statement of a material fact or any omission of a material fact required to be stated
in any registration statement, any preliminary prospectus, final prospectus, summary prospectus, amendment or supplement thereto or necessary
to make the statements therein, in light of the circumstances in which they were made, not misleading, to the extent that such untrue
statement or omission is included or omitted in reliance upon and in conformity with written information furnished by the Holder or its
representative to the Company for use in the preparation thereof, and such Holder shall reimburse the Company, and such Holders, directors,
officers, partners, legal counsel and accountants, persons, underwriters, or control persons, each such director, officer, and controlling
person for any legal or other expenses reasonably incurred by them in connection with investigating, defending, or settling any such
loss, claim, damage, liability, action, or proceeding; provided, however, that the indemnity obligation of a Holder under
this Section 8(b) shall in no event exceed the amount of the net proceeds received by such Holder as a result of the sale of such Holder’s
Registrable Securities pursuant to such registration statement, except in the case of fraud or willful misconduct. Such indemnity shall
remain in full force and effect, regardless of any investigation made by or on behalf of the Company or any such director, officer or
controlling person and shall survive the transfer by any Holder of such shares.


 


(c)
Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a claim referred to
in this Section 8 (including any governmental action), such indemnified party shall, if a claim in respect thereof is to be made against
an indemnifying party, give written notice to the indemnifying party of the commencement of such action; provided, that the failure
of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under this Section,
except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action is brought
against an indemnified party, unless in the reasonable judgment of counsel to such indemnified party a conflict of interest between such
indemnified and indemnifying parties may exist or the indemnified party may have defenses not available to the indemnifying party in
respect of such claim, the indemnifying party shall be entitled to participate in and to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to
assume the defense thereof, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses subsequently
incurred by the latter in connection with the defense thereof, unless in such indemnified party’s reasonable judgment a conflict
of interest between such indemnified and indemnifying parties arises in respect of such claim after the assumption of the defenses thereof
or the indemnifying party fails to defend such claim in a diligent manner, other than reasonable costs of investigation. Neither an indemnified
nor an indemnifying party shall be liable for any settlement of any action or proceeding effected without its consent. No indemnifying
party shall, without the consent of the indemnified party, consent to entry of any judgment or enter into any settlement, which does
not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all
liability in respect of such claim or litigation. Notwithstanding anything to the contrary set forth herein, and without limiting any
of the rights set forth above, in any event any party shall have the right to retain, at its own expense, counsel with respect to the
defense of a claim. Each indemnified party shall furnish such information regarding itself or the claim in question as an indemnifying
party may reasonably request in writing and as shall be reasonably required in connection with defense of such claim and litigation resulting
therefrom.


 




    	11



    	 



    




 


(d)
If an indemnifying party does not or is not permitted to assume the defense of an action pursuant to Section 8(c) or in the case of the
expense reimbursement obligation set forth in Sections 8(a) and 8(b), the indemnification required by Sections 8(a) and 8(b) shall be
made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or
expenses, losses, damages, or liabilities are incurred.


 


(e)
If the indemnification provided for in Section 8(a) or 8(b) is held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, liability, claim, damage or expense referred to herein, the indemnifying party, in lieu of indemnifying
such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss,
liability, claim, damage or expense (i) in such proportion as is appropriate to reflect the proportionate relative fault of the indemnifying
party on the one hand and the indemnified party on the other (determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or omission relates to information supplied by the indemnifying party or the indemnified party and
the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission),
or (ii) if the allocation provided by clause (i) above is not permitted by applicable law or provides a lesser sum to the indemnified
party than the amount herein provided, then in such proportion as is appropriate to reflect not only the proportionate relative fault
of the indemnifying party and the indemnified party, but also the relative benefits received by the indemnifying party on the one hand
and the indemnified party on the other, as well as any other relevant equitable considerations. No indemnified party guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any indemnifying
party who was not guilty of such fraudulent misrepresentation.


 


(f)
Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement
entered into in connection with an underwritten public offering are in conflict with the foregoing provisions, the provisions in the
underwriting agreement shall control.


 




    	12



    	 



    

 


(g)
Other Indemnification. Indemnification similar to that specified in this Section (with appropriate modifications) shall be given
by the Company and each Holder of Registrable Securities with respect to any required registration or other qualification of securities
under any federal or state law or regulation or governmental authority other than the Securities Act.


 


9.
Rule 144. For a period of at least two (2) years following the Effective Date, the Company will use its commercially reasonable
efforts to timely file all reports required to be filed by the Company after the date hereof under the Exchange Act and the rules and
regulations adopted by the Commission thereunder, and if the Company is not required to file reports pursuant to such sections, it will
prepare and furnish to the Holders and make publicly available in accordance with Rule 144(c) such information as is required for the
Holders to sell shares of Common Stock under Rule 144.


 


10.
Independent Nature of Each Holder’s Obligations and Rights. The obligations of each Holder under this Agreement are several
and not joint with the obligations of any other Holder, and each Holder shall not be responsible in any way for the performance of the
obligations of any other Holder under this Agreement. Nothing contained herein and no action taken by any Holder pursuant hereto, shall
be deemed to constitute such Holders as a partnership, an association, a joint venture, or any other kind of entity, or create a presumption
that the Holders are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by
this Agreement. Each Holder shall be entitled to independently protect and enforce its rights, including without limitation the rights
arising out of this Agreement, and it shall not be necessary for any other Holder to be joined as an additional party in any proceeding
for such purpose.


 


11.
Miscellaneous.


 


(a)
Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the United States of America and
the State of New York, both substantive and remedial, without regard to New York conflicts of law principles. Any judicial proceeding
brought against any of the parties to this Agreement or any dispute arising out of this Agreement or any matter related hereto shall
be brought in the courts of the State of New York, New York County, or in the United States District Court for the Southern District
of New York and, by its execution and delivery of this Agreement, each party to this Agreement accepts the jurisdiction of such courts.
The foregoing consent to jurisdiction shall not be deemed to confer rights on any person other than the parties to this Agreement.


 


(b)
Remedies. In the event of a breach by the Company or by a Holder of any of their respective obligations under this Agreement,
each Holder or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law and under this Agreement,
including recovery of damages, shall be entitled to specific performance of its rights under this Agreement.


 




    	13



    	 



    

 


(c)
Successors and Assigns. Except as otherwise provided herein, the provisions hereof shall inure to the benefit of, and be binding
upon, the successors, Permitted Assignees, executors and administrators of the parties hereto.


 


(d)
No Inconsistent Agreements. The Company has not entered, as of the date hereof, and shall not enter, on or after the date of this
Agreement, into any agreement with respect to its securities that would have the effect of impairing the rights granted to the Holders
in this Agreement or otherwise conflicts with the provisions hereof. Notwithstanding anything to the contrary contained herewith, except
as specifically provided in this Agreement, any action by the Company which could have the effect of diminishing the value of any Registrable
Securities, including, without limitation, the issuance of additional stock or other securities, the granting of registration rights
to others, and actions in connection with the operation of the business of the Company, shall not by itself, absent bad faith, be deemed
an impairment of the rights granted to the Holders in this Agreement.


 


(e)
Entire Agreement. This Agreement and the documents, instruments and other agreements specifically referred to herein or delivered
pursuant hereto constitute the full and entire understanding and agreement between the parties with regard to the subjects hereof.


 


(f)

be in writing and will be deemed given to a party (a) on the date of delivery, if delivered to the appropriate address by hand or by
nationally recognized overnight courier service (costs prepaid); (b) the date of transmission if sent by facsimile or e-mail with confirmation
of transmission by the transmitting equipment if such notice or communication is delivered prior to 5:00 P.M., New York City time, on

not a Trading Day or later than 5:00 P.M., New York City time, on any Trading Day; (c) the date received or rejected by the addressee,
if sent by certified mail, return receipt requested; or (d) seven days after the placement of the notice into the mails (first class

by facsimile transmission or by an e- mail, which contains a portable document format (.pdf) file of an executed signature page, such

____________________________________________________________


 ____________________________________________________________


 


6.
Method of Distribution:


 


Describe
below Holder’s intended method of distribution.





 


_______________________________________________________________________________________ 


 





 






1 Beneficially
Owned: A “beneficial owner” of a security includes any person who, directly or indirectly, through any contract,
arrangement, understanding, relationship or otherwise has or shares (i) voting power, including the power to direct
the voting of such security, or (ii) investment power, including the power to dispose of, or direct the
disposition of, such security. In addition, a person is deemed to have “beneficial ownership” of a security of which
such person has the right to acquire beneficial ownership at any time within 60 days, including, but not limited to, any
right to acquire such security: (i) through the exercise of any option, warrant or right, (ii) through the conversion of any
security or (iii) pursuant to the power to revoke, or the automatic termination of, a trust, discretionary account or similar
arrangement.


 


It
is possible that a security may have more than one “beneficial owner,” such as a trust, with two co-trustees sharing voting
power, and the settlor or another third party having investment power, in which case each of the three would be the “beneficial
owner” of the securities in the trust. The power to vote or direct the voting, or to invest or dispose of, or direct the investment
or disposition of, a security may be indirect and arise from legal, economic, contractual or other rights, and the determination of beneficial
ownership depends upon who ultimately possesses or shares the power to direct the voting or the disposition of the security.


 


The
final determination of the existence of beneficial ownership depends upon the facts of each case. You may, if you believe the facts warrant
it, disclaim beneficial ownership of securities that might otherwise be considered “beneficially owned” by you.


 


2
Affiliate: An “affiliate” is a company or person that directly, or indirectly through one or more intermediaries,
controls you, or is controlled by you, or is under common control with you.
