Data Knights Acquisition Corp. 

Trident Court, 1 Oakcroft Road

United Kingdom

 

[__], 2021

 

Ladies and Gentlemen:

 

Data Knights Acquisition Corp.
(the “Company”), a blank check company formed for the purpose of acquiring one or more businesses or entities (a “Business
Combination”), intends to register its securities under the Securities Act of 1933, as amended (“Securities Act”), in
connection with its initial public offering (“IPO”), pursuant to a registration statement on Form S-1 (“Registration
Statement”).

 

The undersigned hereby commits
that it will purchase 525,275 units of the Company (“Private Units”), each Private Unit consisting of one share of Class A
common stock of the Company, par value $0.0001 per share (the “Class A Common Stock”), and one-half of one warrant (the
 “Warrants”) entitling its holder to purchase one (1) share of Class A Common Stock, for a purchase price of $5,252,750
(the “Private Unit Purchase Price”).

 

The undersigned hereby agrees
that it will purchase an additional amount of units of the Company (“Over-Allotment Units”), up to a maximum of 60,000 Over-Allotment
Units, or a maximum purchase price of $600,000 (“Over-Allotment Unit Purchase Price”, together with the Private Unit Purchase
Price, the “Purchase Price”), in the event Kingswood Capital Markets, division of Benchmark Investments, Inc. (“Kingswood”)
exercises its over-allotment option, such that the amount held in the trust account (as described in the Registration Statement) does
not fall below $10.20 per share for each share of Class A Common Stock sold in the IPO.

 

At least twenty-four (24) hours
prior to the effective date of the Registration Statement, the undersigned will cause the Private Unit Purchase Price to be delivered
to Nelson Mullins Riley & Scarborough LLP (“Nelson Mullins”), counsel for the Company, by wire transfer as set forth
in the instructions attached as Exhibit A to hold in a non-interest bearing account until the Company consummates the IPO.

 

The consummation of the purchase
and issuance of the Private Units shall occur simultaneously with the consummation of the IPO and the consummation of the purchase and
issuance of the Over-Allotment Units shall occur simultaneously with the closing of any exercise of the over-allotment option related
to the IPO. Simultaneously with the consummation of the IPO, Nelson Mullins shall deposit the Private Unit Purchase Price, without interest
or deduction, into the trust fund (“Trust Fund”) established by the Company for the benefit of the Company’s public
shareholders as described in the Registration Statement. If the Company does not complete the IPO within ten (10) days from the date
of this letter, the Private Unit Purchase Price (without interest or deduction) will be returned to the undersigned.

 

Each of the Company, and the
undersigned acknowledges and agrees that Nelson Mullins is serving hereunder solely as a convenience to the parties to facilitate the
purchase of the Private Units and Nelson Mullins’s sole obligation under this letter agreement is to act with respect to holding
and disbursing the Private Unit Purchase Price as described above. Nelson Mullins shall not be liable to the Company, Kingswood or the
undersigned or any other person or entity in respect of any act or failure to act hereunder or otherwise in connection with performing
its services hereunder unless Nelson Mullins has acted in a manner constituting gross negligence or willful misconduct. The Company and
the undersigned shall indemnify Nelson Mullins against any claim made against it (including reasonable attorney’s fees) by reason
of it acting or failing to act in connection with this letter agreement except as a result of its gross negligence or willful misconduct.
Nelson Mullins may rely and shall be protected in acting or refraining from acting upon any written notice, instruction or request furnished
to it hereunder and believed by it to be genuine and to have been signed or presented by the proper party or parties.

 

     

     

    

 

The Private Units and Over-Allotment
Units will be identical to the units to be sold by the Company in the IPO. Additionally, the undersigned agrees:

 

		·	to vote the shares of Class A Common Stock included in the Private Units and Over-Allotment Units
in favor of any proposed Business Combination;

 

		·	not to propose, or vote in favor of, an amendment to the Company’s Amended and Restated Certificate
of Incorporation that would affect the substance or timing of the Company’s obligation to redeem 100% of the Company’s shares
of Class A Common Stock sold in the IPO if the Company does not complete an initial Business Combination within 12 months from the
closing of the IPO (or up to 18 months from the closing of the IPO if the Company extends the period of time to consummate an initial
Business Combination as described in more detail in the prospectus included in the Registration Statement), unless the Company provides
the holders of shares of Class A Common Stock sold in the IPO with the opportunity to redeem their shares of Class A Common
Stock upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount of the Trust Fund, including
interest earned on Trust Fund and not previously released to the Company to pay the Company’s franchise and income taxes, divided
by the number of then outstanding shares of Class A Common Stock sold in the IPO;

 

		·	not to convert any shares of Class A Common Stock included in the Private Units and Over-Allotment
Units into the right to receive cash from the Trust Fund in connection with a shareholder vote to approve either a Business Combination
or an amendment to the provisions of the Company’s Amended and Restated Certificate of Incorporation, and not to tender the Private
Units and Over-Allotment Units in connection with a tender offer conducted prior to the closing of a Business Combination;

 

		·	the undersigned will not participate in any liquidation distribution with respect to the Private Units
and Over-Allotment Units (but will participate in liquidation distributions with respect to any units or shares of Class A Common
Stock purchased by the undersigned in the IPO or in the open market) if the Company fails to consummate a Business Combination;

 

		·	that the Private Units, Over-Allotment Units and underlying securities will not be transferable until
after the consummation of a Business Combination except (i) to the Company’s pre-IPO shareholders, or to the Company’s
officers, directors, advisors and employees, (ii) transfers to the undersigned’s affiliates or its members upon its liquidation,
(iii) to relatives and trusts for estate planning purposes, (iv) by virtue of the laws of descent and distribution upon death,
(v) pursuant to a qualified domestic relations order, (vi) by private sales made in connection with the consummation of a Business
Combination at prices no greater than the price at which the Private Units were originally purchased or (vii) to the Company for
cancellation in connection with the consummation of a Business Combination, in each case (except for clause vii) where the transferee
agrees to the terms of the transfer restrictions; and

 

		·	the Private Units and Over-Allotment Units will include any additional terms or restrictions as is customary
in other similarly structured blank check company offerings or as may be reasonably required by the underwriters in the IPO in order to
consummate the IPO, each of which will be set forth in the Registration Statement.

 

The undersigned acknowledges
and agrees that the purchaser of the Private Units and Over-Allotment Units will execute agreements in form and substance typical for
transactions of this nature necessary to effectuate the foregoing agreements and obligations prior to the consummation of the IPO as are
reasonably acceptable to the undersigned, including but not limited to an insider letter.

 

The undersigned hereby represents
and warrants that:

 

		(a)	it has been advised that the Private Units and Over-Allotment Units have not been registered under the
Securities Act;

 

     

     

    

 

		(b)	it will be acquiring the Private Units and Over-Allotment Units for its account for investment purposes
only;

 

		(c)	it has no present intention of selling or otherwise disposing of the Private Units and Over-Allotment
Units in violation of the securities laws of the United States;

 

		(d)	it is an “accredited investor” as defined by Rule 501 of Regulation D promulgated under
the Securities Act of 1933, as amended;

 

		(e)	it has had both the opportunity to ask questions and receive answers from the officers and directors of
the Company and all persons acting on its behalf concerning the terms and conditions of the offer made hereunder;

 

		(f)	it is familiar with the proposed business, management, financial condition and affairs of the Company;

 

		(g)	it has full power, authority and legal capacity to execute and deliver this letter and any documents contemplated
herein or needed to consummate the transactions contemplated in this letter; and

 

		(h)	this letter constitutes its legal, valid and binding obligation, and is enforceable against it.

 

This letter agreement constitutes
the entire agreement between the undersigned and the Company with respect to the purchase of the Private Units and Over-Allotment Units,
and supersedes all prior and contemporaneous understandings, agreements, representations and warranties, both written and oral, with respect
to the same.

STOCK
ISSUANCE AGREEMENT

 

This Stock Issuance Agreement
(this “Agreement”) is entered into as of October 3, 2017 (the “Execution Date”), by
and between Inmune Bio Inc., a Nevada corporation (the “Company”),
and Xencor, Inc., a Delaware corporation (“Xencor”), and
is intended by the parties to satisfy certain of the Company’s obligations to Xencor under Section 4.1 of the License Agreement
(as defined below) between the Company and Xencor. Capitalized terms used but not defined in this Agreement shall have the meaning ascribed
to such terms in the License Agreement.

 

Recitals

 

Whereas,
Xencor and the Company are entering into that certain License Agreement of even date herewith (the “License Agreement”),
pursuant to which Xencor will grant the Company a license to certain intellectual property rights of Xencor as more fully set forth in
the terms of the License Agreement (the “Licensed Rights”);

 

Whereas,
pursuant to Section 4.1 of the License Agreement, as partial consideration for the Licensed Rights, the Company has agreed (i) to
issue to Xencor 1,585,000 shares (the “Initial Shares”) of the Company’s common stock, par value $0.001
per share (the “Common Stock”), on the Execution Date, which Initial Shares shall equal 19.0% of the Fully Diluted
Company Shares (as defined below) immediately following such issuance, and (ii) grant Xencor the option to purchase up to an additional
number of shares of Common Stock that shall equal 10.0% of the then Fully Diluted Company Shares immediately following such purchase (the
“Additional Shares” and together with the Initial Shares, the “Shares”) for an aggregate
purchase price of $10,000,000 with respect to the purchase of such Additional Shares, at any time during the six-year period commencing
on the Execution Date (the “Option”); and

 

Whereas,
the Company desires to issue the Shares and grant the Option to Xencor, and Xencor desires to acquire the Shares and the Option, on the
terms set forth in this Agreement.

 

Now, Therefore, It Is Hereby
Agreed between the parties as follows:

 

AGREEMENT

 

1.
Issuance of Common Stock.

 

(a) Xencor
hereby agrees to acquire from the Company, and the Company hereby agrees to issue to Xencor, (i) the Initial Shares and (ii) the Option.
The Company acknowledges that the issuance of the Shares and the Option to Xencor is irrevocable and non-refundable and is not conditioned
upon whether the Company achieves any success with its licensing of Licensed Patent Rights, whether the Company develops, uses or sells
any Licensed Products, or any other thing or event except as expressly described in the License Agreement. The closing of the issuance
and acquisition of the Initial Shares and the Option (the “Initial Closing”) shall occur at the offices of the
Company immediately following execution of this Agreement, or at such other time and place as the parties
may mutually agree (such date, the “Closing Date”). Promptly following the Initial Closing, the Company will
deliver a certificate representing the Initial Shares to Xencor at the address set forth for Xencor on the signature page hereto.

 

     

     

    

 

(b) The Option.

 

(i) By
execution and delivery of this Agreement, the Company hereby grants to Xencor the Option. The aggregate purchase price for the full exercise
of the Option to acquire the Additional Shares shall be $10,000,000, which purchase price shall be pro-rated for any partial exercise
of the Option for less than the full 10% of the Fully Diluted Company Shares immediately following such purchase. The Option shall be
exercised by Xencor delivering written notice to the Company (the “Exercise Notice”), with payment in full for
the shares due at the time of such written notice, subject to Section 1(b)(ii) below. The Company shall issue the Additional Shares as
directed in writing by Xencor, within five business days of receipt of the Exercise Notice and payment of the purchase price.

 

(ii) The
purchase price for the Additional Shares being purchased pursuant to the Option may be paid either (i) by cash or wire transfer of immediately
available funds, (ii) by surrender of a number of the Additional Shares which have a fair market value equal to the aggregate purchase
price of the Additional Shares being purchased (“Net Issuance”) as determined herein, or (iii) any combination
of the foregoing. If Xencor elects the Net Issuance method of payment, the Company shall issue to Xencor upon exercise a number of Additional
Shares determined in accordance with the following formula:

 

	X=	Y(A-B)	 
	 	A	 

 

	 	where: X =	the number of Additional Shares to be issued to Xencor;
	 	 	 
	 	Y =	the number of Additional Shares with respect to which Xencor is exercising its purchase rights under the Option, which for clarity, upon full exercise of the Option will equal 10% of the Fully Diluted Company Shares outstanding following the purchase of the Additional Shares;
	 	A =	the fair market value of one (1) share of the Additional Shares on the date of exercise; and
	 	B =	$10,000,000 / Y.

 

No fractional shares
arising out of the above formula for determining the number of shares to be issued to Xencor shall be issued, and the Company shall
in lieu thereof make payment to Xencor of cash in the amount of such fraction multiplied by the fair market value of one (1) share
of the Additional Shares on the date of exercise. For purposes of the above calculation, the fair market value of one (1) share of
the Additional Shares shall mean (a) if the Common Stock is then traded on a securities exchange, the closing price of such Common
Stock on such on the last trading day prior to the date of exercise, (b) if the Common Stock is then regularly traded
over-the-counter, the closing sale prices or secondarily the closing bid of such Common Stock on the last trading day prior to the
date of exercise, or (c) if there is no active public market for the Common Stock, the fair market value of one share of the
Additional Shares as reasonably determined in good faith by the Board of Directors of the Company.

 

    2

     

    

 

		(iii)	If at any time:

 

		(1)	the Company shall declare any cash dividend upon its Common
Stock;

  

		(2)	there shall be any Acquisition (as defined below) or capital reorganization or reclassification of the
                                                                capital stock of the Company;

 

		(3)	there shall be a voluntary or involuntary dissolution, liquidation
or winding-up of the Company; or

 

		(4)	there shall be an initial public offering of the Company’s securities;

 

then, in any one or more of said cases, the
Company shall give, by first class mail, postage prepaid, addressed to Xencor at the address of Xencor as shown on the books of the
Company, (a) at least ten (10) days prior written notice of the date on which the books of the Company shall close or a record shall
be taken for such dividend or for determining rights to vote in respect of any such Acquisition, reorganization, reclassification,
dissolution, liquidation, winding-up or public offering, and (b) in the case of any such Acquisition, reorganization,
reclassification, dissolution, liquidation, winding-up or public offering, at least ten (10) days prior written notice of the date
when the same shall take place. Any notice given in accordance with the foregoing clause (a) shall also specify, in the case of any
such dividend, the date on which the holders of Common Stock shall be entitled thereto. Any notice given in accordance with the
foregoing clause (b) shall also specify the date on which Xencor shall be entitled to exchange the Additional Shares for securities
or other property deliverable upon such Acquisition, reorganization, reclassification, dissolution, liquidation, winding-up,
conversion or public offering, as the case may be. As used herein, “Acquisition” shall mean any of the
following: (i) the acquisition of the Company by another entity by means of any transaction or series of related transactions
(including without limitation, any reorganization, stock sale, merger or consolidation but, excluding any merger effected
exclusively for the purpose of changing domicile of the Company); or (ii) a sale of all or substantially all of the assets of the
Company; unless the Company’s stockholders of record as constituted immediately prior to such acquisition or sale will,
immediately after such acquisition or sale (by virtue of securities issued as consideration for the Company’s acquisition or
sale or otherwise) hold at least 50% of the voting power of surviving or acquiring entity.

 

    3

     

    

 

(c) For
purposes of this Agreement, “Fully Diluted Company Shares” means, at any point in time, the aggregate
number of (A) shares of Common Stock outstanding, plus (B) the number of shares of Common Stock issuable upon the conversion of all
shares of preferred stock of the Company and/or convertible debt of the Company outstanding plus (C) the number of shares of Common
Stock issuable upon conversion or exercise, as the case may be, of all issued and outstanding securities of the Company convertible
into, exercisable for, or exchangeable for, directly or indirectly, shares of Common Stock outstanding at such time, including but
not limited to, issued and outstanding options and warrants to purchase Common Stock and disregarding any vesting restrictions or
similar provisions. For the avoidance of doubt, “Fully Diluted Company Shares” does not include the number
of shares of Common Stock reserved for issuance at such time under any stock option, equity incentive or similar plan for unissued
securities of the Company.

provision of any mortgage, indenture, contract, lease, agreement, instrument or contract to which it is party or by which it is bound

The execution, delivery, and performance of and compliance with this Agreement, and the Voting Agreement, and the issuance and sale of
the Shares pursuant hereto, will not, with or without the passage of time or giving of notice, result in any such material violation,
or be in conflict with or constitute a material default under any such term or provision, or result in the creation of any mortgage, pledge,
lien, encumbrance or charge upon any of the properties or assets of the Company or the suspension, revocation, impairment, forfeiture
or nonrenewal of any permit, license, authorization or approval applicable to the Company, its business or operations or any of its assets
or properties.

 

(l) Litigation.
There is no action, suit, proceeding or investigation pending or, to the Company’s knowledge, currently threatened against the
Company that would reasonably be expected to result, either individually or in the aggregate, in any material adverse change in the assets,
condition, affairs or prospects of the Company, financially or otherwise, or any change in the current equity ownership of the Company
or that questions the validity of this Agreement or the Voting Agreement or the right of the Company to enter into any of such agreements,
or to consummate the transactions contemplated hereby or thereby. The foregoing includes, without limitation, actions pending or, to
the Company’s knowledge, threatened involving the prior employment of any of the Company’s employees, their use in connection
with the Company’s business of any information or techniques allegedly proprietary to any of their former employers, or their obligations
under any agreements with prior employers. The Company is not a party or subject to the provisions of any order, writ, injunction, judgment
or decree of any court or government agency or instrumentality. There is no action, suit, proceeding or investigation by the Company
currently pending or which the Company intends to initiate.

(federal, state and local) required to be filed by it. All taxes shown to be due and payable on such returns, any assessments imposed,
and to the Company’s knowledge all other taxes due and payable by the Company on or before the Closing, have been paid or will be
paid prior to the time they become delinquent. The Company has not been advised (a) that any of its returns, federal, state or other,
have been or are being audited as of the date hereof, or (b) of any deficiency in assessment or proposed judgment to its federal, state
or other taxes. The Company has no knowledge of any liability of any tax to be imposed upon its properties or assets as of the date of
this Agreement that is not adequately provided for.

 

(n) Employees.
The Company has no collective bargaining agreements with any of its employees. There is no labor union organizing activity pending or,
to the Company’s knowledge, threatened with respect to the Company. The Company is not a party to or bound by any currently effective
employment contract, deferred compensation arrangement, bonus plan, incentive plan, profit sharing plan, retirement agreement or other
employee compensation plan or agreement. No employee of the Company has been granted the right to continued employment by the Company
or to any material compensation following termination of employment with the Company. To the Company’s knowledge, no employee of
the Company, nor any consultant with whom the Company has contracted, is in violation of any term of any employment contract, proprietary
information agreement or any other agreement relating to the right of any such individual to be employed by, or to contract with, the
Company; and to the Company’s knowledge the continued employment by the Company of its present employees, and the performance of
the Company’s contracts with its independent contractors, will not result in any such violation. The Company has not received any
notice alleging that any such violation has occurred. The Company is not aware that any officer, key employee or group of employees intends
to terminate his, her or their employment with the Company, nor does the Company have a present intention to terminate the employment
of any officer, key employee or group of employees. There are no actions pending, or to the Company’s knowledge, threatened, by
any former or current employee concerning such person’s employment by the Company.

 

(o) Voting
Rights. To the Company’s knowledge, except as contemplated in the Voting Agreement, no stockholder of the Company has entered
into any agreement with respect to the voting of equity securities of the Company.

 

(p) Compliance
with Laws; Permits. The Company is not in violation of any applicable statute, rule, regulation, order or restriction of any
domestic or foreign government or any instrumentality or agency thereof in respect of the conduct of its business or the ownership
of its properties, which violation would materially and adversely affect the business, assets, liabilities, financial condition,
operations or prospects of the Company. No governmental orders, permissions, consents, approvals or authorizations are required to
be obtained and no registrations or declarations are required to be filed in connection with the execution and delivery of this
Agreement or the issuance of the Shares, except such as have been duly and validly obtained or filed, or with respect to any filings
that must be made after the Initial Closing, as will be filed in a timely manner. The Company has all franchises, permits, licenses
and any similar authority necessary for the conduct of its business as now being conducted by it, the lack of which could materially
and adversely affect the business, assets, properties or financial condition of the Company and believes it can obtain, without
undue burden or expense, any similar authority for the conduct of its business as planned to be conducted.

 

    8

     

    

 

(q) Offering
Valid. Assuming the accuracy of the representations and warranties of Xencor contained in Section 3 hereof, the issuance of the Shares
will be exempt from the registration requirements of the Securities Act of 1933, as amended (the “Act”), and
will have been registered or qualified (or are exempt from registration and qualification) under the registration, permit or qualification
requirements of all applicable state securities laws. Neither the Company nor any agent on its behalf has solicited or will solicit any
offers to sell or has offered to sell or will offer to sell all or any part of the Shares to any person or persons so as to bring the
sale of such Shares by the Company within the registration provisions of the Act or any state securities laws.

 

(r) Real
Property Holding Corporation. The Company is not a real property holding corporation within the meaning of Code Section 897(c)(2)
and any regulations promulgated thereunder.

 

3. Investment
Representations. In connection with the acquisition of the Initial Shares, the Additional Shares and the Option, Xencor hereby represents
and warrants to the Company as follows:

 

(a) Xencor
is aware of the Company’s business affairs and financial condition and is acquiring the Shares and the Option for investment for
Xencor’s own account only and not with a view to, or for resale in connection with, any “distribution” thereof within
the meaning of the Act.

 

(b) Xencor
understands that the Shares and the Option have not been registered under the Act by reason of a specific exemption therefrom, which exemption
depends upon, among other things, the bona fide nature of Xencor’s investment intent as expressed herein.

 

(c) Xencor
further acknowledges and understands that the Shares and the Option must be held indefinitely unless the Shares and/or Option are subsequently
registered under the Act or an exemption from such registration is available. Xencor understands that the certificate evidencing the Shares
will be imprinted with the legend set forth in Section 7(a) which prohibits the transfer of the Shares unless the Shares are registered
or such registration is not required in the opinion of counsel for the Company.

 

(d) Xencor
is familiar with the provisions of Rule 144, under the Act, as in effect from time to time, which, in substance, permit limited public
resale of “restricted securities” or “control securities” acquired, directly or indirectly, from the issuer thereof
(or from an affiliate of such issuer), in a non-public offering subject to the satisfaction of certain conditions. The Shares may be resold
by Xencor in certain limited circumstances subject to the provisions of Rule 144, which requires, among other things: (i) the availability
of certain public information about the Company and (ii) the resale occurring following the required holding period under Rule 144 after
Xencor has purchased, and made full payment of (within the meaning of Rule 144), the securities to be sold.

 

    9

     

    

 

(e) Xencor
further understands that at the time it wishes to sell the Shares, there may be no public market upon which to make such a sale, and that,
even if such a public market then exists, the Company may not be satisfying the current public information requirements of Rule 144, and
in such event, Xencor would be precluded from selling the Shares under Rule 144 even if the minimum holding period requirement had been
satisfied.

 

(f) Xencor
represents that Xencor is an “accredited investor” as that term is defined in Rule 501 of Regulation D promulgated by the
Securities and Exchange Commission under the Act.

 

4. Xencor’s
Conditions to Closing. Xencor’s obligations to receive the Initial Shares and the Option at the Initial Closing are subject
to the satisfaction, at or prior to the Closing Date, of the following conditions:

 

(a) Representations
and Warranties True; Performance of Obligations. The representations and warranties made by the Company in Section 2 hereof shall

or prior to the Initial Closing.

 

(b) Legal
Investment. On the Closing Date, the issuance of the Initial Shares shall be legally permitted by all laws and regulations to which

Articles of Incorporation as in effect at the time of the Initial Closing, (ii) the Company’s Bylaws as in effect at the time of
the Initial Closing, (iii) resolutions approved by the Company’s Board of Directors authorizing the transactions contemplated hereby,
and (iv) good standing certificates (including tax good standing) with respect to the Company from the applicable authority(ies) in Nevada
and any other jurisdiction in which the Company is qualified to do business, dated a recent date before the Initial Closing.

 

    10

     

    

 

(g) Voting
Agreement. The Voting Agreement substantially in the form attached hereto as Exhibit A shall have been executed and delivered
by the parties thereto. The stock certificates representing the outstanding shares subject to the Voting Agreement shall have been delivered
to the Secretary of the Company and shall have had appropriate legends placed upon them to reflect the restrictions on transfer set forth
in the Voting Agreement.

 

(h) Board
of Directors. Upon the Initial Closing, the authorized size of the Board of Directors of the Company shall be six members and the
Board shall consist of David Moss, Raymond J. Tesi, Mark Lowdell, Tim Schroeder, Kelly Ganjei and Edgardo Baracchini.

 

(i) Legal
Opinion. Xencor shall have received from legal counsel to the Company an opinion addressed to them, dated as of the Closing Date,
in substantially the form attached hereto as Exhibit B.

 

(j) Proceedings
and Documents. All corporate and other proceedings in connection with the transactions contemplated at the Initial Closing hereby
and all documents and instruments incident to such transactions shall be reasonably satisfactory in substance and form to Xencor and its
counsel, and Xencor and its counsel shall have received all such counterpart originals or certified or other copies of such documents
as they may reasonably request.

 

5. The
Company’s Conditions to Closing. The Company’s obligations herein are subject to the satisfaction, at or prior to the
Closing Date, of the following conditions:

 

(a) Representations
and Warranties True; Performance of Obligations. The representations and warranties made by Xencor in Section 3 hereof shall be true
and correct in all material respects as of the Closing Date with the same force and effect as if they had been made as of the Closing
Date, and Xencor shall have performed all obligations and conditions herein required to be performed or observed by it on or prior to
the Initial Closing.

 

(b) License
Agreement. The License Agreement shall be executed on the date of this Agreement.

 

6.
Limitations on Transfer.

 

(a) Xencor
agrees that it shall not assign, hypothecate, donate, encumber or otherwise dispose of any interest in the Shares except in compliance
with the provisions herein and applicable securities laws. Furthermore, the Shares shall be subject to any right of first refusal in favor
of the Company or its assignees that may be contained in the Company’s Bylaws as of the Execution Date. Xencor acknowledges that
it may be required to hold the Shares acquired hereunder indefinitely. During the period of time during which Xencor holds the Shares,
the value of the Common Stock may increase or decrease, and any risk associated with such Common Stock and such fluctuation in value shall
be borne by Xencor.

 

    11

     

    

 

(b) Xencor
agrees not to make any disposition of all or any portion of the Shares unless and until:

 

(i) there
is then in effect a registration statement under the Act, covering such proposed disposition and such disposition is made in accordance
with such registration statement; or

 

(ii) (A)
the proposed transferee has agreed in writing to be bound by the transfer restrictions and other obligations and restrictions on Xencor
contained in this Agreement, (B) Xencor has notified the Company of the proposed disposition and has furnished the Company with a statement
of the circumstances surrounding the proposed disposition, and

(C) if reasonably requested by the
Company, Xencor has furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will
not require registration of such Shares under the Act. It is agreed that the Company will not require opinions of counsel for transactions
made pursuant to Rule 144, except in unusual circumstances.

 

7. Restrictive
Legends. All certificates representing the Shares (or any portion thereof) shall have endorsed thereon legends in substantially the
following forms (in addition to any other legend which may be required by other agreements between the parties hereto executed after the
date hereof):

 

(a) “THE
SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AS AMENDED. THEY MAY NOT BE SOLD, OFFERED
FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES UNDER SAID ACT OR AN OPINION
OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED”; and

 

(b)
Any legend required by applicable blue sky laws.

 

The Company shall be obligated
to promptly reissue unlegended certificates at the request of Xencor (or a permitted transferee) if the Company becomes subject to the
reporting requirements of the Securities Exchange Act of 1934, as amended, and such holder has obtained an opinion of counsel (which counsel
may be counsel to the Company) reasonably acceptable to the Company to the effect that the securities proposed to be disposed of may lawfully
be so disposed of without registration, qualification and legend. Any legend endorsed on an instrument pursuant to applicable state securities
laws and the stop-transfer instructions with respect to such securities shall be removed upon receipt by the Company of an order of the
appropriate blue sky authority authorizing such removal.

 

8. Registration
Rights. The Company agrees that it shall file a registration statement under the Act (the “Registration
Statement”) by November 30, 2017, and shall seek to have such Registration Statement declared effective within six
months of such filing (such filing deadline and effectiveness deadline, the “Registration Deadlines”). The
Registration Statement will register the resale of the outstanding Shares held by Xencor at the time of the filing. The Registration
Statement will also seek to register additional shares of Common Stock for sale directly by the Company, with an intent to apply for
inclusion on the Nasdaq Stock Market or lesser market if the Company does not meet Nasdaq Stock Market requirements. If the Company
fails to meet either of the Registration Deadlines, Xencor will be entitled to receive a cash payment in the amount of 1% of the
product of (i) the number of Shares then outstanding multiplied by (ii) $1.50 (such product, the “Penalty
Product”) for each month that a Registration Deadline is not met, up to a maximum of 12% of the Penalty Product
(Registration Penalty”). Notwithstanding the foregoing, the Company shall not be obligated to pay any
Registration Penalty if the Company is unable to fulfill its registration obligations as a result of rules, regulations, positions
or releases issued or actions taken by the Securities and Exchange Commission (“SEC”) pursuant to its
authority with respect to “Rule 415”, and the Company registers at such time the maximum number of shares
of Common Stock permissible upon consultation with the staff of the SEC. Any such reduction in the number of shares registrable
hereunder shall first reduce the Shares required to be registered hereunder, before reducing any other shares in such Registration
Statement. “Rule 415” means Rule 415 promulgated by the SEC under the Securities Act of 1933, as amended,
as such rule may be amended from time to time, or any other similar or successor rule or regulation of the SEC providing for
offering securities on a continuous or delayed basis.

 

    12

     

    

 

If and to
the extent any Shares shall be excluded from a Registration Statement as a result of Rule 415, the Company shall use its commercially
reasonable best efforts to have such Shares registered on a subsequent Registration Statement as soon as reasonably practicable, and in
any case will file such subsequent Registration Statement by November 30, 2019.

 

9. Protective
Provisions. The Company agrees that until the earlier of (i) the date on which the Company has satisfied the following two conditions:
(A) the Company has received aggregate gross cash proceeds of not less than $40,000,000 (before underwriting
discounts, commissions and fees) in a bona fide equity financing or series of bona fide equity financings and (B)
the Company becomes subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (if
both conditions (A) and (B) are satisfied, a “Qualified Offering”) or (ii) a sale of all or substantially
all of the Company’s business to which the License Agreement relates, whether by merger, sale of stock, sale of assets or otherwise
(a “Qualified Sale”), for so long as Xencor holds at least 415,583 Shares (as adjusted for any stock dividends,
combinations, splits, recapitalizations and the like with respect to such shares after the date hereof), in addition to any other vote
or consent required by the Company’s Articles of Incorporation or Bylaws, the vote or written consent of the holders of a majority
of the Shares then outstanding shall be necessary for effecting or validating the following actions (whether by merger, recapitalization
or otherwise):

 

(a) Any
authorization or any designation, whether by reclassification or otherwise, of any new class or series of stock or any other securities
convertible into equity securities of the Company ranking on a parity with or senior to the Shares in right of redemption, liquidation
preference, voting or dividend rights or any increase in the authorized or designated number of any such class or series;

 

(b)
Any agreement by the Company or its stockholders regarding a Qualified Sale;

 

(c) Any
voluntary dissolution, liquidation, transaction or series of transactions deemed to be a liquidation of the Company;

 

    13

     

    

 

(d) The
creation of any encumbrance on, or the grant of a security interest in, all or substantially all of the assets of the Company in connection
with the incurrence of indebtedness by the Company;

 

(e) Any
declaration or payment of any dividend or distribution by the Company to its stockholders; or

 

(f) Any
repurchase by the Company of shares of the Company’s Preferred Stock (except as otherwise provided in the Company’s Articles
of Incorporation) or Common Stock (except (a) acquisitions of Common Stock by the Company pursuant to agreements that permit the Company
to repurchase such shares at no more than cost upon termination of services to the Company or (b) acquisitions of Common Stock in exercise
of the Company’s right of first refusal to repurchase such shares upon approval by the Company’s Board of Directors).

 

10. Future
Securities Issuances. With respect to any equity securities or securities convertible into equity securities issued by the Company
to any person after the date hereof, in the event the Company issues any such additional securities entitling the holder thereof to rights,
preferences, privileges or other terms and conditions more favorable to such holder than those applicable to Xencor with respect to the
Shares, then the Company shall take any and all action necessary or appropriate in order to amend its Articles of Incorporation or other
governing or charter documents, this Agreement and/or the Voting Agreement, as applicable, in order to provide substantially the same
or similar rights, preferences, privileges and other terms and conditions to Xencor with respect to the Shares. The rights provided to
Xencor pursuant to this Section 10 shall terminate upon a Qualified Offering.

 

11.
Information Rights.

 

(a) To
the extent requested by Xencor, as soon as practicable after the end of each fiscal year of the Company, and in any event within 120 days
thereafter, the Company will furnish Xencor a balance sheet of the Company, as at the end of such fiscal year, and a statement of income
and a statement of cash flows of the Company, for such year, all prepared in accordance with generally accepted accounting principles
consistently applied (except as noted therein) and setting forth in each case in comparative form the figures for the previous fiscal
year, all in reasonable detail. Such financial statements shall be accompanied by a report and opinion thereon by independent public accountants
selected by the Company’s Board of Directors.

 

(b) To
the extent requested by Xencor, the Company will furnish Xencor, as soon as practicable after the end of the first, second and third quarterly
accounting periods in each fiscal year of the Company, and in any event within 50 days thereafter, a balance sheet of the Company as of
the end of each such quarterly period, and a statement of income and a statement of cash flows of the Company for such period and for
the current fiscal year to date, prepared in accordance with generally accepted accounting principles consistently applied (except as
noted therein), with the exception that no notes need be attached to such statements and year-end audit adjustments may not have been
made.

 

    14

     

    

 

(c) If
at any time there is not an individual serving on the Board of Directors of the Company that was designated by Xencor pursuant to the
Voting Agreement, then to the extent requested by Xencor, the Company will furnish Xencor (i) at least thirty (30) days prior to the beginning
of each fiscal year an annual budget and operating plans for such fiscal year (and as soon as available, any subsequent written revisions
thereto); and (ii) as soon as practicable after the end of each month, and in any event within twenty (20) days thereafter, a balance
sheet of the Company as of the end of each such month, and a statement of income and a statement of cash flows of the Company for such
month and for the current fiscal year to date, including a comparison to plan figures for such period, prepared in accordance with generally
accepted accounting principles consistently applied (except as noted thereon), with the exception that no notes need be attached to such
statements and year-end audit adjustments may not have been made.

 

(d) Xencor
shall have the right to visit and inspect any of the properties of the Company or any of its subsidiaries, and to discuss the affairs,
finances and accounts of the Company or any of its subsidiaries with its officers, and to review such information as is reasonably requested
all at such reasonable times and as often as may be reasonably requested; provided, however, that the Company shall not be obligated
under this Section 11(d) with respect to a competitor of the Company or with respect to information which the Company’s Board of
Directors determines in good faith is confidential or attorney-client privileged and should not, therefore, be disclosed.

 

(e) The
rights provided to Xencor pursuant to this Section 11 shall terminate upon a Qualified Offering.

 

12. Board
Observer Rights. For as long as Xencor shall hold at least five percent (5%) of the outstanding Common Stock of the Company, the Company
shall allow one representative designated by Xencor to attend all meetings of the Board in a nonvoting capacity, and in connection therewith,
the Company shall give such representative copies of all notices, minutes, consents and other materials, financial or otherwise, which
the Company provides to its Board of Directors; provided, however, that the Company reserves the right to exclude such representative
from access to any material or meeting or portion thereof if the Company believes upon advice of counsel that such exclusion is reasonably
necessary to preserve the attorney-client privilege, to protect highly confidential information or for other similar reasons. The decision
of the Board of Directors with respect to the privileged or confidential nature of such information shall be final and binding.

 

13. Market
Stand-Off Agreement. Xencor agrees that it shall not sell, dispose of, transfer, make any short sale of, grant any option for
the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale of, any Common Stock or
other securities of the Company held by Xencor (whether now held or subsequently acquired), including the Shares (the
“Restricted Securities”), during the 180-day period following the effective date of a registration
statement of the Company filed under the Act in connection with the Company’s Initial Offering (or such longer period, not to
exceed 34 days after the expiration of the 180-day period, as the underwriters or the Company shall request in order to facilitate
compliance by the underwriters with NASD Rule 2711 or NYSE Member Rule 472 or any successor or similar rule or regulation). Xencor
agrees to execute and deliver such other agreements as may be reasonably requested by the Company and/or the managing underwriters
which are consistent with the foregoing or which are necessary to give further effect thereto. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to Restricted Securities held by Xencor until the end of
such period. The underwriters of the Company’s stock are intended third party beneficiaries of this Section 13 and shall have
the right, power and authority to enforce the provisions hereof as though they were a party hereto. If requested by any such
underwriter, Xencor will enter into an agreement directly for the benefit of the underwriter, containing substantially the same
terms set forth above.

 

    15

signed by each of the parties hereto.

 

(f) Severability. If
one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to renegotiate such
provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such
provision, then (i) such provision shall be excluded from this Agreement, (ii) the balance of this Agreement shall be interpreted as
if such provision were so excluded and (iii) the balance of this Agreement shall be enforceable in accordance with its terms.

 

(g) Counterparts;
Delivery by Facsimile. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original and all

OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION
THEREFOR PRIOR TO SUCH QUALIFICATION OR IN THE ABSENCE OF AN EXEMPTION FROM SUCH QUALIFICATION IS UNLAWFUL. PRIOR TO ACCEPTANCE OF SUCH
CONSIDERATION BY THE COMPANY, THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED
