    -1- 

     

    

(B)
The Board of Directors, subject to the provisions hereof, may classify or reclassify any unissued Shares of Preferred Stock into one

Shares:

(ix)
The conditions or restrictions, if any, upon the creation of indebtedness of the Corporation or any subsidiary and the conditions or
restrictions, if any, upon the issuance of any additional stock (including additional Shares of such Series or of any other Series) ranking

(x)
Any right to vote with holders of Shares of any other Series or class and any right to vote as a class, either generally or as a condition

(xi)
Such other preferences, rights, restrictions, and qualifications as shall not be inconsistent herewith.

 

(C)
All Shares of any Series of Preferred Stock shall be identical with each other in all respects, except that Shares of any one Series
issued at different times may differ as to the dates from which dividends thereon shall be cumulative, if cumulative dividends have been
designated for such Series, and all Series shall rank equally and be identical in all respects, except as permitted by the foregoing
provisions of Section (2) hereof.

 

(D)
The Preferred Stock is senior to the Common Stock, and the Common Stock is subject to the rights and preferences of the Preferred Stock
as herein set forth.

 

(E)(i)
The holders of Preferred Stock of each Series shall be entitled to receive, and the Corporation shall be bound to pay, out of any funds
legally available for such purpose, when and as declared by the Board of Directors, cash dividends thereon at such rate and payable at
such times as shall be fixed and determined for such Series as herein set forth. Dividends with respect to each Series of Preferred Stock
shall be cumulative or non-cumulative, as determined by the Board of Directors, and shall accrue from such date or dates as shall have
been fixed and determined with respect to such Series by the Board of Directors as herein provided.

    -3- 

     

    

(ii)
In no event, so long as any Preferred Stock shall remain outstanding, shall any dividend whatsoever be declared or paid upon, or any
distribution be made or ordered in respect of, the Common Stock or any other class of stock ranking junior to the Preferred Stock, or
any moneys be set aside for or applied to the purchase or redemption (through a sinking fund or otherwise) of Shares of Common Stock
or of any other such junior class of stock, unless:

 

(a)
Full cumulative dividends on the Preferred Stock of all Series for all past dividend periods shall have been paid with respect to any
outstanding Preferred Shares having cumulative dividend rights, and the full dividend on all outstanding Shares of Preferred Stock of
all Series for the then current dividend period, if any, shall have been paid or declared and set apart for payment; and

 

(b)
The Corporation shall have set aside all amounts, if any, theretofore required to be set aside as and for sinking funds, if any, for
the Preferred Stock of all Series for the then current year, and all defaults, if any, in complying with any such sinking fund requirements
in respect of previous years shall have been made good.

 

(iii)
Subject to the foregoing provisions respecting the Preferred Stock, and not otherwise, dividends, payable in cash, stock, or otherwise,
as may be determined by the Board of Directors, may be declared and paid upon the Common Stock, from time to time, out of any funds legally
available therefore, and no holder of any Shares of any Series of Preferred Stock, as such, shall be entitled to participate in any such
dividend.

 

(F)
The Corporation, at the option of the Board of Directors, may, at any time permitted by the resolution or resolutions adopted by the
Board of Directors providing for the issuance of any Series of Preferred Stock, and at the redemption price per Share fixed and determined
for such Series, redeem the whole or any part of the Shares of such Series at the time outstanding (the total sum so payable on any such
redemption being herein referred to as the “redemption price”). Notice of every such redemption shall be mailed to the holders
of record of the Shares of such Series so to be redeemed at their respective addresses as the same shall appear on the books of the Corporation.
Such notice shall be mailed at least 30 days in advance of the date designated for such redemption to the holders of record of Shares
so to be redeemed. In case of the redemption of a part only of any Series at the time outstanding, the Shares of such Series so to be
redeemed shall be selected by lot or pro rate in such manner as the Board of Directors may determine.

    -4- 

     

    

(G)
If, on the redemption date specified in such notice, the funds necessary for such redemption shall have been set aside by the Corporation,
separate and apart from its other funds, in trust for the pro rata benefit of the holders of the Shares so called for redemption, then,
notwithstanding that any certificates for Shares of Preferred Stock so called for redemption shall not have been surrendered for cancellation,
the Shares represented thereby shall no longer be deemed outstanding, the right to receive dividends thereon shall cease to accrue from
and after the date of redemption so designated, and all rights of holders of the Shares of Preferred Stock so called for redemption shall
forthwith, after such redemption date, cease and terminate, excepting only the right of the holders thereof to receive the redemption
price therefore but without interest. Any moneys so set aside by the Corporation and unclaimed at the end of six years from the date
designated for such redemption shall revert to the general funds of the Corporation; after which reversion, the holders of such Shares
so called for redemption shall look only to the Corporation for payment of the redemption price, and such Shares shall not still be deemed
to be outstanding.

 

(H)
Upon any liquidation, dissolution, or winding up of the Corporation, whether voluntary or involuntary, the Preferred Stock of each Series
shall be entitled, before any distribution shall be made to the Common Stock or to any other class of stock junior to the Preferred Stock,
to be paid the amount fixed and determined by the board of Directors for such Series as herein provided, plus accrued and unpaid dividends
thereon to the date of distribution, but the Preferred Stock shall not be entitled to any further payment, and any remaining net assets
shall be distributed ratably to the outstanding Common Stock. If, upon such liquidation, dissolution, or winding up of the Corporation,
whether voluntary or involuntary, the net assets of the Corporation shall be insufficient to permit the payment to all outstanding Shares
of Preferred Stock of all Series of the full preferential amounts to which they are respectively entitled, then the entire net assets
of the Corporation shall be distributed ratably to all outstanding Shares of Preferred Stock of all Series in proportion to the full
preferential amount to which each Share is entitled. Neither a consolidation nor a merger of the Corporation with or into any other corporation
or corporations, nor the sale of all or substantially all of the assets of the Corporation, shall be deemed to be a liquidation, dissolution,
or winding up within the meaning of this section.

    -5- 

     

    

(I)
The Preferred Stock shall not be convertible, except to the extent that any one or more Series thereof may be issued with the privilege
of conversion as may be determined by the Board of Directors prior to issuance of any Shares of such Series as herein set forth. If the
Shares of any Series are so issued with the privilege of conversion, then, at the option of the respective holders thereof, the Preferred
Stock of such Series shall be convertible into a number of fully paid and non-assessable Shares of the Common Stock or any other class
of stock of the Corporation at the conversion rate, or upon payment to the Corporation of the conversion price, which is in effect for
the Preferred Stock of such Series at the time of such conversion.

 

The
initial conversion rate or conversion price (including, in the latter case, the number of Shares of Common Stock or other class of stock
issuable upon conversion), and the terms and conditions of conversion for each Series issued with the privilege of conversion shall be
fixed and determined by the Board of Directors as hereinafter provided. Such conversion price or conversion rate, with respect to any
such Series, may be subject, from time to time, to adjustment by virtue of issuance of securities or rights to purchase securities of
the Corporation, or upon any capital reorganization or reclassification of the Common Stock of the Corporation, or the consolidation
or merger of the Corporation, or the sale, conveyance, lease, or other transfer by the Corporation of all or substantially all of its
property, or in other circumstances, all to the extent and in the manner fixed and determined by the Board of Directors as herein set
forth.

 

(J)
Shares of any Series of Preferred Stock which have been issued and reacquired in any manner by the Corporation (including Shares redeemed,
Shares purchased and retired, and Shares which, if convertible or exchangeable, have been converted into or exchanged for Shares of stock
of any other class, classes, or Series) shall have the status of authorized and unissued Shares of Preferred Stock and may be reissued
as a part of the Series of which they were originally a part, or may be reclassified and reissued as part of a new Series of Preferred
Stock to be created by resolution or resolutions of the Board of Directors, or as part of any other Series of Preferred Stock, all subject
to the conditions or restrictions on issuance set forth in any resolution or resolutions adopted by the Board of Directors provided for
the issue of any Series of Preferred Stock.

    -6- 

     

    

(K)
None of the holders of Preferred Stock of any Series shall have any voting powers for any purpose, except as may be specifically required
by law, or except as any such right to vote may be fixed and determined by the Board of Directors prior to issuance of any Shares of
such Series as herein provided.

 

(L)
In order the Board of Directors to establish a Series of Preferred Stock, the Board of Directors shall adopt a resolution or resolutions
setting forth the designation and the number of Shares of such Series and the relative rights and preferences thereof in respect of the
foregoing particulars. The Board of Directors may re-designate any Shares of any Series theretofore established that have not been issued,
or that have been issued and retired, as Shares of some other Series, or change the designation of outstanding Shares where desired to
prevent confusion.

 

(M)
For the purposes hereof and of any resolution of the Board of Directors providing for the classification or reclassification of any Shares
of Preferred Stock:

 

(i)
The term “outstanding,” when used in reference to Shares of stock, shall mean issued Shares, excluding Shares
held by the Corporation or a subsidiary, and Shares called for redemption; funds for the redemption of which shall have been deposited
in trust;

    -7- 

     

    

COMMON
STOCK

 

Subject
to the foregoing provisions, dividends may be declared on the Common Stock, and each Share of Common Stock shall entitle the holder thereof
to one vote in all proceedings in which action shall be taken by stockholders of the Corporation.

 

THIRD:
That said amendment was duly adopted in accordance with provisions of Section 78.390 of the Nevada General Corporation Law.

 

The
number of voting rights of the corporation outstanding and entitled to vote on an amendment to the Articles of Incorporation is 79.88%
that said changes and amendment have been consented to and approved by a majority vote of the stockholders holding a majority of the
voting rights of the stock outstanding and entitled to vote thereon.

stock dividend or other distribution with respect to such shares), requesting that the Company effect a public offering under the Securities Act of all or part of the Registrable Securities held by such Stockholders and specifying the intended
method or methods of disposition of such Registrable Securities, the Company will promptly give written notice of such requested registration to all Stockholders and will use its best efforts to effect the registration under the Securities Act, as
expeditiously as is reasonable, of: 
 (i) the Registrable Securities that the Company has been so requested to register by
such Stockholders, for disposition in accordance with the intended method of disposition stated in such request; and 
 (ii)
all other Registrable Securities that the Company has been requested to register by other Stockholders by written request delivered to the Company within 30 days after the receipt of such written notice delivered by the Company; 

all to the extent required to permit the disposition (in accordance with the intended methods thereof as aforesaid) of the Registrable Securities so to be
registered. Anything herein to the contrary notwithstanding, the Company shall not be obligated to consummate more than two (2) registrations pursuant to this Section 2(a); provided, that in each case at least
eighty percent (80%) of the Registrable Securities requested to be registered are registered and sold to the public. In connection with any underwritten offering with respect to which Stockholders shall have requested registration pursuant to this
Section 2(a), the Company shall have the right to select the lead managing underwriter (being an underwriting firm of national standing) with respect to such offering, such underwriter to be reasonably acceptable to the
Stockholders requesting the registration. Should the Stockholders requesting the registration so elect, they may select an underwriting firm of national standing which is reasonably acceptable to the Company to act as
co-lead manager of such offering. 
 (b) Incidental Registration. If at any time after the
Effective Time the Company proposes to file a registration statement under the Securities Act with respect to an offering for its own account or for the sale of equity securities of any holder of any class of equity security of the Company
(excluding the Company’s initial public offering of Common Stock, unless such first public offering includes the registration of securities for the account of other Stockholders, and excluding a registration relating solely either to the sale
of securities to employees of the Company pursuant to a stock purchase, stock option or similar plan, or a merger, recapitalization or reorganization), the Company shall promptly give each Stockholder written notice of such registration at least
thirty (30) days prior to the anticipated filing date and such notice shall offer the Stockholders the opportunity to register such number of Registrable Securities as each Stockholder may request. Upon the written request of any such
Stockholder given to the Company within twenty (20) days after receipt of such notice delivered by the Company, the Company shall, subject to the provisions of Section 2(d), use its best efforts to cause to be
registered under the Securities Act all of the Registrable Securities that each such Stockholder has requested to be registered. 

  
 -4- 

 (c) Registration on Form S-3. If at any time
after the Effective Time (i) any Stockholder or Stockholders request that the Company file a registration statement on Form S-3 or any successor thereto for a public offering of all or any portion of the
Registrable Securities held by such requesting holder or holders, the reasonably anticipated aggregate price to the public of which would exceed $3,000,000, and (ii) the Company is a registrant entitled to use Form S-3 or any successor thereto to register such Registrable Securities, then the Company shall use its best efforts to, as soon as practicable, register under the Securities Act on Form
S-3 or any successor thereto, for public sale in accordance with the method of disposition specified in such notice, the number of Registrable Securities specified in such notice. The number of registrations
on Form S-3 which may be requested and obtained under this Section 2(c) shall be limited to no more than two (2) per calendar year. 

(d) Underwriting Requirements. In connection with any underwritten offering pursuant to Section 2(a), if the
managing underwriter shall advise the Company that, in its view, the number or proposed mix of securities requested to be included in such registration (including securities which the Company desires to be included which are not Registrable
Securities) exceeds the largest number of securities which can be sold without having a material adverse effect on such offering (the “Maximum Offering Size”), including the price at which such securities can be sold, the Company
will include in such registration: 
 (i) first, shares of Common Stock issued or issuable upon conversion of the
shares of Preferred Stock requested by the Stockholders to be included in such registration pursuant to Section 2(a), with the shares so included to be apportioned pro rata among the Stockholders according to the
total number of such shares of Common Stock owned by each such Stockholder (including any shares of Common Stock issued or issuable upon conversion of the Preferred Stock) or in such other proportions as shall be agreed upon by such Stockholders, if
the total number of shares requested to be included in such registration by the Stockholders exceeds the Maximum Offering Size; 

(ii) second, any Registrable Securities other than the ones referenced in (i) above requested by the Stockholders
to be included in such registration pursuant to Section 2(a), with the shares so included to be apportioned pro rata among the Stockholders according to the total number of Registrable Securities owned by each such
Stockholder (excluding any shares of Preferred Stock or shares of Common Stock issued or issuable upon conversion of the Preferred Stock, but assuming the conversion into Common Stock of all outstanding Convertible Securities other than such
Preferred Stock) or in such other proportions as shall be agreed upon by such Stockholders, to the extent such total amount of Registrable Securities requested to be included in such registration by the Stockholders exceeds the Maximum Offering
Size; and 

  
 -5- 

 (iii) third, after registration of the total amount of Registrable
Securities requested to be included in such registration by the Stockholders, any securities to be sold for the account of other Persons (including the Company) which shall not cause the Maximum Offering Size to be exceeded, with such priorities
among the Company and such other Persons as the Company shall determine. 
 In connection with any underwritten offering pursuant to
Section 2(b), if the managing underwriter shall advise the Company that, in its view, the number or mix of securities (including all Registrable Securities) which the Company, the Stockholders and any other Persons intend
to include in such registration exceeds the Maximum Offering Size, the Company will include in such registration, in the priority listed below, securities up to the Maximum Offering Size: 

(iv) first, securities to be sold for the Company’s own account; 

(v) second, Registrable Securities requested to be included in such registration by Stockholders pursuant to
Section 2(b) with the shares so included to be apportioned pro rata among the Stockholders according to the total amount of Registrable Securities owned by each such Stockholder calculated on a fully diluted basis
(i.e., assuming the conversion into Common Stock of all outstanding Convertible Securities) or in such other proportions as shall be agreed upon by such Stockholders (if necessary); and 

(vi) third, shares of Common Stock requested to be included in such registration by all other Persons, allocated (if
necessary) pro rata among such Persons on the basis of the relative number of securities each such Person has requested to be included in such registration, or as such Persons may otherwise agree. 

(e) Expenses of Registration. The Company shall bear and pay all expenses incurred in connection with any registration, filing or
qualification of shares with respect to registrations pursuant to this Section 2, including, without limitation, all registration, filing, qualification, Blue Sky, printing and accounting fees relating or apportionable
thereto, but excluding underwriting discounts and commissions relating to shares being registered, applicable transfer taxes and expenses of counsel to the Stockholders, which shall be borne by the Stockholders selling shares being registered.
Notwithstanding anything in this paragraph to the contrary, upon demand of the Stockholders, the Company shall pay the reasonable expenses of one separate counsel for the Stockholders to be selected by the Stockholders holding a majority of the
Registrable Securities held by Stockholders and included in such registration, filing or qualification. 
 (f) Company Delay or
Withdrawal of Registration. At the time of any request to register Registrable Securities pursuant to Section 2(a), if the Board of Directors of the Company determines in its good faith reasonable judgment that the
Company should not file any registration statement otherwise required to be filed pursuant to such Section 2(a) because the Company is engaged in or plans to engage in any financing, acquisition or other material
transaction which would be adversely affected by the filing of such a registration statement, the Company shall be entitled to postpone for the shortest reasonable period of time (but not exceeding ninety (90) days from the date of the
request), the filing of such registration statement and shall promptly give the Stockholders who have requested the filing of such registration statement under Section 2(a) and any other Stockholders who have requested the

  
 -6- 

 
registration of their Registrable Securities under Section 2(a) written notice of such determination, containing a general statement of the reasons for such postponement
and an approximation of the anticipated delay. If the Company shall so postpone the filing of the registration statement, the Stockholders who made the request for registration under Section 2(a) shall have the right to
withdraw the request for registration by giving written notice to the Company within thirty (30) days after receipt of the notice of postponement. Such right to delay a request for registration pursuant to this
Section 2(f) may not be exercised more than once in any twelve (12) month period. Without limiting the foregoing, the Company shall have no liability to any Stockholder for the Company’s withdrawal of any
registration as to which a Stockholder has registration rights under Section 2(b) (except reimbursement of expenses incurred prior to such withdrawal in accordance with paragraph (e) above); provided, that such
withdrawal is made by the Company in good faith and not for the purpose of impairing any Stockholder’s rights under such Section 2(b). 

(g) Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the SEC which may at any time
permit the sale of the Registrable Securities by the Stockholders to the public without registration, at all times after ninety (90) days after any registration statement covering a public offering of securities of the Company under the
Securities Act shall have become effective, the Company agrees to: 
 (i) make and keep public information available, as
those terms are understood and defined in Rule 144 under the Securities Act; 
 (ii) use its best efforts to file with the
SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and 

(iii) furnish to each Stockholder holding Registrable Securities forthwith upon request a written statement by the Company as
to its compliance with the reporting requirements of such Rule 144 and of the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed by the Company as
such Stockholder may reasonably request in availing itself of any rule or regulation of the SEC allowing such Stockholder to sell any Registrable Securities without registration. 

(h) Obligations of the Company. Whenever required under this Section 2 to effect the registration of any
Registrable Securities, the Company shall, as expeditiously as reasonably possible:

(ii) prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in
connection therewith as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement; 

  
 -7- 

 (iii) furnish to the Stockholders such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of the shares owned by them and covered by a registration
statement filed under this Section 2;  
 (iv) use its best efforts to register and qualify
the securities covered by such registration statement under such other securities or Blue Sky laws of such states or jurisdictions as shall be reasonably requested by the Stockholders; provided, that the Company shall not be required in
connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions; 

(v) in the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement,
in usual and customary form, with the managing underwriter(s) of such offering (and each Stockholder participating in such underwriting shall also enter into and perform its obligations under such an underwriting agreement); 

(vi) notify each Stockholder holding shares covered by such registration statement as promptly as possible at any time when a
prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material
fact or omits to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading and promptly prepare (and file with the SEC) and furnish to
such Stockholders a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Securities, such prospectus shall not include an untrue statement of
a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; 

(vii) furnish, at the request of any Stockholder requesting registration of shares pursuant to this
Section 2, on the date that such shares are delivered to the underwriters for sale in connection with a registration pursuant to this Section 2 (if such shares are being sold through underwriters)
or, if such shares are not being sold through underwriters, on the date that the registration statement with respect to such shares becomes effective, (i) an opinion, dated as of such date, of counsel representing the Company for the purposes
of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the Stockholders participating in such registration of shares, and (ii) a
“comfort” letter, dated as of such date, from the independent certified public accountants of the Company, in form and substance as in customarily given by independent certified public accountants to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and to the Stockholders requesting registration of shares; 

  
 -8- 

 (viii) notify Stockholders whose shares are included in the registration
statement promptly of any request by the SEC for the amendment or supplement of such registration statement or prospectus or for additional information, and notify such Stockholders promptly of the filing of each amendment or supplement to such
registration statement or prospectus; 
 (ix) advise Stockholders whose shares are included in the registration statement,
promptly after it shall receive notice, of the issuance of any stop order by the SEC suspending the effectiveness of such registration statement or the initiation or threatening of any proceeding for that purpose and promptly use its best efforts to
prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued; 
 (x) furnish to
each Stockholder whose shares are included in the registration statement at least one conformed copy of the registration statement and any amendments thereto; 

(xi) provide each Stockholder whose shares are included in the registration statement and its representatives a reasonable
opportunity, after entering into a confidentiality agreement which is reasonably satisfactory to the Company, to conduct an inquiry of the Company’s financial and other records during normal business hours and make available during normal
business hours and without unreasonable disruption to the Company’s business or operations, its officers, directors and employees to provide such information as such Stockholder may reasonably request to fulfill any due diligence obligations
that such Stockholder may have; 
 (xii) keep the registration statement effective for a period ending on the earlier of the
date that is ninety (90) days from the effective date of the registration statement or such time as the Stockholders have completed the distribution described in the registration statement; 

(xiii) cause all Registrable Securities registered on the registration statement to be listed each national securities exchange
on which similar securities issued by the Company are then listed; and 
 (xiv) provide a transfer agent and registrar for
all Registrable Securities registered pursuant to this Agreement and provide a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration. 

(i) Obligations of Stockholders. In connection with any registration required to be effected pursuant to this
Section 2, the Stockholders selling any shares in connection with such registration shall furnish to the Company such information regarding themselves, the shares held by them and the intended method of disposition of such
shares as shall be required or reasonably necessary to effect the registration of their shares. 

  
 -9- 

 (j) Lock-Up Agreement. Each Stockholder
hereby agrees that in connection with any registration of securities of the Company relating to an underwritten offering thereof to the general public, to the extent requested by the Company or the underwriter of such offering, such Stockholder (to
the extent such Stockholder then holds, individually or together with its Affiliates, two percent (2%) or more of the outstanding shares of Common Stock, or is an officer, director or employee of the Company) shall not, whether or not such
Stockholder is participating in such registration, sell, contract to sell, grant any option or right to purchase, lend, pledge, enter into any swap or other arrangement that transfers economic consequences of ownership or otherwise transfer or
dispose of (other than in a private sale or to donees who agree to be similarly bound) any shares of Common Stock or any other securities convertible into Common Stock (other than those shares, if any, which are in fact included in such
registration) without the prior written consent of the Company or the applicable underwriters, as the case may be, for such period (the “Lock-Up Period”) of time (not to exceed (x) one
hundred eighty (180) days with respect to the initial public offering of the Common Stock, or (y) ninety (90) days with respect to any other offering) from the effective date of the registration statement for such registration as the
Company or such underwriters may specify in writing. Each Stockholder hereby further agrees that (to the extent such Stockholder then holds, individually or together with its Affiliates, two percent (2%) or more of the outstanding shares of Common
Stock, or is an officer, director or employee of the Company), if reasonably requested by any underwriter or underwriters in any such offering, such Stockholder shall enter into a lock-up agreement in the form
(containing customary terms) reasonably requested by such underwriter or underwriters for such offering, provided, that such lock-up agreement does not provide (i) for a longer lock-up period than the Lock-Up Period contained in this Section 2(j) or (ii) terms that are more onerous to such Stockholder than those
applicable to any similarly situated Stockholder. Each Stockholder further agrees that the underwriters of any such offering are intended to be third-party beneficiaries of this Section 2(j) and such beneficiaries shall be
entitled to enforce the provisions of this Section 2(j) an their own behalf as though they were a party hereto. The provisions of this Section 2(j) shall not be deemed to prevent the Stockholders
from exercising their rights under Section 2(b) hereof in connection with any such underwritten offering. 
 (k)
Indemnification. The Company will, and hereby does, indemnify and hold harmless, in the case of any registration statement filed pursuant to this Section 2, each seller of any Registrable Securities covered by such
registration statement, its directors and officers, each other person who participates as an underwriter in the offering or sale of such securities, each officer and director of each such underwriter, and each such other person, if any, who controls
such seller or any such underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, (collectively, the “Seller Indemnitees”), against any losses, claims, damages, liabilities and
expenses, joint or several, to which such Seller Indemnitee may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages, liabilities or expenses (or actions or proceedings in respect thereof) arise out of or are
based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such securities were registered under the Securities Act, any preliminary prospectus, final prospectus or
summary prospectus included therein, or any amendment or supplement thereto, or any document incorporated by reference therein; (ii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading; and (iii) any violation by the Company of any applicable securities laws in connection with such registration statement, preliminary prospectus, final prospectus or summary prospectus, or any related
“free 

  
 -10- 

 
writing prospectus”, or amendment or supplement thereto or document incorporated by reference therein; and the Company will reimburse such Seller Indemnitee for any legal or any other
expenses reasonably incurred by them in connection with investigating or defending such loss, claim, liability, action or proceeding; provided, however, that the Company shall not be liable to any Seller Indemnitee in any such case to
the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration
statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement, or any document incorporated by reference therein, in reliance upon and in conformity with written information furnished to the Company for
use in the preparation thereof by such Seller Indemnitee. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of any Seller Indemnitee and shall survive the transfer of such securities by such
seller. 
 The Company may require, as a condition to including any Registrable Securities in any registration statement pursuant to this
Section 2, that the Company shall have received an undertaking satisfactory to it from each prospective seller of such securities, to, severally and not jointly, indemnify and hold harmless (in the same manner and to the
same extent as set forth in the preceding paragraph, except that no such prospective seller shall in any event be liable pursuant thereto for any amount in excess of the net proceeds of sale received by such seller from the sale by it of Registrable
Securities under such registration statement) the Company, each officer and director of each such underwriter and each other person, if any, who controls the Company or the underwriter, and each other seller, with respect to any statement in or
omission from such registration statement, any preliminary prospectus, final prospectus or summary prospectus included therein, or any amendment or supplement thereto, or any related “free-writing prospectus”, or any document incorporated
by reference therein, but only if such statement or omission was made in reliance upon and in conformity with written information furnished by such indemnifying prospective seller to the Company for use in the preparation of or inclusion in such
registration statement, preliminary prospectus, final prospectus, summary prospectus, amendment or supplement, or document incorporated by reference therein. 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, controlling person or other seller and shall survive the transfer of such securities by such seller. The indemnity contemplated by this paragraph shall not apply to amounts paid in
settlement of any losses, claims, damages, liabilities or expenses (or actions in respect thereof) if such settlement is effected without the consent of the Stockholder from whom indemnification is sought (which consent shall not be unreasonably
withheld or delayed). 
 Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding (including
a governmental investigation) involving a claim referred to in this Section 2(k), such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this
Section 2(k), give written notice to the latter of the commencement of such action; provided, however, that the failure of any indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations under the preceding provisions of this Section 2(k), 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 such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties 

  
 -11- 

 
may exist in respect of such claim (in which case, the indemnifying party shall be liable for the fees and expenses of one counsel for the underwriters and other sellers in connection with any
one action or separate but similar or related actions), the indemnifying party will be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified, to the extent that it may wish, 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 thereon, the indemnifying party will not be liable to such indemnified party
for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof (except as expressly set forth above). 

(l) Rights of Stockholders. No person shall be granted registration rights which conflict with or which are more favorable to such
Stockholder than the registration rights set forth in this Agreement. At the election of the Company and the holders of greater than fifty percent (50%) of the total number of then issued and outstanding shares of Preferred Stock held by all
Stockholders (including for purposes of this calculation any issued and outstanding shares of Common Stock issued upon conversion of shares of Preferred Stock), which Stockholders shall include Mitsui and Kirin, respectively, so long as Mitsui or
Kirin, as applicable, owns at least fifty percent (50%) of the number of shares of Preferred Stock (including for purposes of this calculation any issued and outstanding shares of Common Stock issued upon conversion of shares of Preferred Stock)
owned by them, respectively, as of the Effective Time (subject to proportionate adjustment in the case of any stock split, reverse stock split, recapitalization, reclassification stock dividend or other distribution with respect to such shares), new
stockholders of the Company may be given the opportunity to receive the registration rights provided under this Agreement by being permitted to execute an Instrument of Accession to this Agreement in the form of Exhibit A attached hereto
(and, upon execution, be added to Schedule 1) or be given registration rights on another basis less favorable to such new stockholder. 

3. SEVERABILITY. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any
other provision or any other jurisdiction, but this Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein. 

4. ENTIRE AGREEMENT. Except as otherwise expressly set forth herein, from and after the Effective Time and unless and until thereafter
amended, this document will embody the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and will supersede and preempt any prior understandings, agreements or representations by or among the
parties, written or oral, with respect to such subject matter. 
 5. SUCCESSORS AND ASSIGNS. This Agreement will bind and inure to
the benefit of and be enforceable by the Company and the Stockholders and their respective successors and permitted assigns. 

  
 -12- 

 6. COUNTERPARTS; EFFECTIVENESS OF AGREEMENT. This Agreement may be executed by
original, facsimile, PDF or other electronic signature (including Docusign) and in separate counterparts each of which will be an original and all of which taken together will constitute one and the same agreement. This Agreement shall become
effective as of the Effective Time but automatically shall terminate and be deemed null and void ab initio if the SPRA is terminated or the Closing (as defined in the SPRA) otherwise does not occur for any reason. 

7. REMEDIES. The Stockholders will be entitled to enforce their rights under this Agreement specifically (without posting a bond or
other security), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights existing in their favor. The parties hereto acknowledge and agree that in the event of any breach of this Agreement by
the Company, the Stockholders would be irreparably harmed and could not be made whole by monetary damages. Each party hereto accordingly agrees (a) not to assert by way of defense or otherwise that a remedy at law would be adequate, and
(b) that the parties agree, in addition to any other remedy to which they may be entitled, that the remedy of specific performance of this Agreement is appropriate in any action in court. In the event of any dispute involving the terms of this
Agreement, the prevailing party shall be entitled to collect reasonable fees and expenses incurred by the prevailing party in connection with such dispute from the non-prevailing parties to such dispute. 

8. RECAPITALIZATION, ETC. In the event that any capital stock or other securities are issued in respect of, in exchange for, or in
substitution of, any shares of Common Stock by reason of any reorganization, recapitalization, reclassification, merger, consolidation, spin-off, partial or complete liquidation, stock dividend, split-up, sale of assets, distribution to Stockholders or combination of the Common Stock or any other change in capital structure of the Company, appropriate adjustments shall be made with respect to the relevant
provisions of this Agreement so as to fairly and equitably preserve, as far as practicable, the original rights and obligations of the parties hereto under this Agreement. 

9. AMENDMENT AND WAIVER. No modification, amendment or waiver of any provision of this Agreement will be effective against the Company
or the Stockholders unless such modification, amendment or waiver is approved in writing by the Company and the holders of greater than fifty percent (50%) of the total number of then issued and outstanding shares of Preferred Stock held by all
Stockholders, which holders shall include Mitsui and Kirin, respectively, so long as Mitsui or Kirin, as applicable, owns at least fifty percent (50%) of the number of shares of Preferred Stock (including for purposes of this calculation any issued
and outstanding shares of Common Stock issued upon conversion of shares of Preferred Stock) owned by them, respectively, as of the Effective Time (subject to proportionate adjustment in the case of any stock split, reverse stock split,
recapitalization, reclassification stock dividend or other distribution with respect to such shares); provided, however that no such modification, amendment or waiver shall be effective against any Stockholder who has not consented to
such modification, amendment or waiver to the extent that such modification, amendment or waiver would be adverse to the interests of such Stockholder in any material respect and would have a disproportionate impact in any material respect on the
rights of such Stockholder in its capacity as a Stockholder hereunder when measured against the impact of such modification, amendment or waiver on the rights of other Stockholders in their capacities as Stockholders hereunder.

  
 -13- 

 
The Company shall notify all Stockholders of each modification, amendment or waiver of any provision of this Agreement that could reasonably be expected to affect the rights of such Stockholder
hereunder at least five (5) business days prior to the effectiveness of such modification, amendment or waiver. The failure of any party to enforce any of the provisions of this Agreement will in no way be construed as a waiver of such
provisions and will not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms. 

10. TERMINATION. This Agreement (and the right of any Stockholder to request registration or inclusion of Registrable Securities in any
registration) will terminate with respect to each applicable Stockholder upon the earliest to occur of: 
 (a) any Liquidation Event (as
defined in the Company’s Fifth Amended and Restated Certificate of Incorporation as in effect as of the Effective Time or as amended or modified from time to time); 

(b) such time after consummation of an initial public offering of the Common Stock under the Securities Act as Rule 144 or another similar
exemption under the Securities Act is available for the sale of all of such Stockholder’s shares without limitation during a three-month period without registration; or 

(c) a termination of this Agreement pursuant to Section 6 hereof; 

provided, that the provisions of Section 2(e) and Section 2(k) shall survive any termination
pursuant to Section 10(a) or Section 10(b) above. 
 11. GOVERNING LAW; JURY TRIAL
WAIVER. ALL QUESTIONS CONCERNING THE CONSTRUCTION, VALIDITY AND INTERPRETATION OF THIS AGREEMENT WILL BE GOVERNED BY THE LAWS OF THE STATE OF DELAWARE, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW. THE PARTIES HERETO AGREE TO WAIVE
ANY RIGHT TO HAVE ANY DISPUTE ARISING HEREUNDER OR OTHERWISE IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREBY ADJUDICATED BY A JURY, AND HEREBY AGREE TO SUBMIT TO THE COURTS OF THE STATE OF DELAWARE IN CONNECTION WITH THE RESOLUTION OF ANY
SUCH DISPUTE. 
 12. DESCRIPTIVE HEADINGS. The descriptive headings of this Agreement are inserted for convenience only and do
not constitute a part of this Agreement. 
 13. CONSTRUCTION. The language used in this Agreement will be deemed to be the language
chosen by the parties to express their mutual intent, and no rule of strict construction will be applied against any party.

 14. NOTICES. All notices, demands, and other communications hereunder shall be in
