 29 









	A.	COMMON STOCK 

 The following rights, powers privileges and restrictions, qualifications,
and limitations apply to the Common Stock. 
 1. General. The voting, dividend and liquidation rights of the
holders of the Common Stock are subject to and qualified by the rights, powers and privileges of the holders of the Preferred Stock set forth in this Certificate of Incorporation. 

2. Voting. The holders of the Common Stock are entitled to one vote for each share of Common Stock held at all
meetings of stockholders (and written actions in lieu of meetings). Unless required by law, there shall be no cumulative voting. The number of authorized shares of Common Stock may be increased or decreased (but not below the number of shares
thereof then outstanding) by (in addition to any vote of the holders of one or more series of Preferred Stock that may be required by the terms of the Certificate of Incorporation) the affirmative vote of the holders of shares of capital stock of
the Corporation representing a majority of the votes represented by all outstanding shares of capital stock of the Corporation entitled to vote, irrespective of the provisions of Section 242(b)(2) of the General Corporation Law. 

 

	B.	PREFERRED STOCK 

 The following rights, powers and privileges, and restrictions,
qualifications and limitations, shall apply to the Series A Preferred Stock. Unless otherwise indicated, references to “Sections” in this Part B of this Article VT refer to sections of this Part B. 

1. Liquidation, Dissolution, or Winding Up; Certain Mergers, Consolidations and Asset Sales. 

1.1 Payments to Holders of Preferred Stock. In the event of any voluntary or involuntary liquidation, dissolution, or winding up of the
Corporation or any Deemed Liquidation Event (as defined below), before any payment shall be made to the holders of Common Stock by reason of their ownership thereof, the holders of shares of Preferred Stock then outstanding must be paid out of the
funds and assets available for distribution to its stockholders, an amount per share equal to the greater of (a) the Original Issue Price for such share of Preferred Stock, plus any dividends declared but unpaid thereon, and (b) such
amount per share as would have been payable had all shares of Preferred Stock been converted into Common Stock pursuant to Section 3 immediately prior to such liquidation, dissolution or winding up or Deemed Liquidation
Event. If upon any such liquidation, dissolution, or winding up or Deemed Liquidation Event of the Corporation, the funds and assets available for distribution to the stockholders of the Corporation are insufficient to pay the holders of shares of
Preferred Stock the full amount to which they are entitled under this Section 1.1, the holders of shares of Preferred Stock will share ratably in any distribution of the funds and assets available for distribution in
proportion to the respective amounts that would otherwise be payable in respect of the shares of Series A Preferred Stock held by them upon such distribution if all amounts payable on or with respect to such shares were paid

30. 








 
in full. Prior to the liquidation, dissolution or winding up of the Corporation or any Deemed Liquidation Event, the Corporation shall declare for payment all accrued and unpaid dividends with
respect to the Preferred Stock, but only to the extent of funds of the Corporation are legally available for the payment of dividends. Not less than five business days prior to any payments made pursuant to this
Section 1.1, the Corporation shall deliver written notice of any such liquidation, dissolution or winding up of the Corporation or any Deemed Liquidation Event to each record holder of Preferred Stock (the
“Distribution Note”), setting forth in reasonable detail the amount of proceeds to be paid with respect to each share of Preferred Stock and each share of Common Stock in connection with such liquidation, dissolution or
winding up of the Corporation or any such Deemed Liquidation Event. 
 1.2 Payments to Holders of Common Stock. In the event of any
voluntary or involuntary liquidation, dissolution, or winding up or Deemed Liquidation Event of the Corporation, after the payment of all preferential amounts required to be paid to the holders of shares of Preferred Stock as provided in
Section 1.1, the remaining funds and assets available for distribution to the stockholders of the Corporation will be distributed among the holders of shares of Common Stock, pro rata based on the number of shares of Common
Stock held by each such holder. 
 1.3 Deemed Liquidation Events. 

1.3.1 Definition. Each of the following events is a “Deemed Liquidation Event”: 

(a) a merger or consolidation of the Corporation with or into any other corporation or other business entity (except one in which the holders
of capital stock of the Corporation immediately prior to such merger or consolidation continue to hold immediately after such merger or consolidation at least a majority of the outstanding securities having the right to vote in an election of the
Board of Directors (“Voting Stock”) of the surviving corporation); 
 (b) a sale, lease, exchange, exclusive license
or other transfer (in one transaction or a related series of transactions) of all or substantially all of the Corporation’s assets (other than as part of a merger or consolidation not described in Section 1.3.1(a));
and 
 (c) the acquisition by any person or any group of persons (other than the Corporation, any of its direct or indirect subsidiaries, or
any trustee, fiduciary or other person or entity holding securities under any employee benefit plan or trust of the Corporation or any of its direct or indirect subsidiaries) acting together in any transaction or related series of transactions, of
such number of shares of the Corporation’s Voting Stock as causes such person, or group of persons, to own beneficially, directly or indirectly, as of the time immediately after such transaction or series of transactions, 50% or more of the
combined voting power of the Voting Stock of the Corporation other than as a result of an acquisition of securities directly from the Corporation, or solely as a result of an acquisition of securities by the Corporation which by reducing the number
of shares of the Voting Stock outstanding increases the proportionate voting power represented by the Voting Stock owned by any such person or group of persons to 50% or more of the combined voting power of such Voting Stock.

contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule 406 of the Securities Act of 1933, as amended. 

31. 








 1.3.2 Amount Deemed Paid or Distributed. The funds and assets deemed paid or distributed
to the holders of capital stock of the Corporation upon any such merger, consolidation, sale, transfer or other disposition described in this Section 1.3 will be the cash or the value of the property, rights or securities
paid or distributed to such holders by the Corporation or the acquiring person, firm or other entity. The value of such property, rights or securities shall be determined in good faith by the Board and such valuation will be included in the
Distribution Notice; provided, however, if any holder of Preferred Stock objects to such valuation in writing prior to the distribution referenced in the Distribution Notice, the Corporation will engage a regionally recognized accounting firm
(mutually agreeable to both the Corporation and the objecting stockholder) to determine the value of such property, rights or securities. 

2. Voting. On any matter presented to the stockholders of the Corporation for their action or consideration at any meeting
of stockholders of the Corporation (or by written consent of stockholders in lieu of meeting), each holder of outstanding shares of Preferred Stock may cast the number of votes equal to the number of whole shares of Common Stock into which the
shares of Preferred Stock held by such holder are convertible as of the record date for determining stockholders entitled to vote on such matter. Fractional votes shall not be permitted, and any fractional voting rights available on an as-converted basis (after aggregating all shares into which shares of Preferred stock held by each holder could be converted) will be rounded to the nearest whole number (with
one-half being rounded upward). Except as provided by law or by the other provisions of this Certificate of Incorporation, holders of Preferred Stock shall vote together with the holders of Common Stock as a
single class on an as-converted basis, shall have full voting rights and powers equal to the voting rights and powers of the holders of Common Stock, and shall be entitled, notwithstanding any provision of
this Certificate of Incorporation, to notice of any stockholder meeting in accordance with the Bylaws of the Corporation. 
 3.
Conversion. The holders of the Preferred Stock have the following conversion rights (the “Conversion Rights”): 

3.1 Optional Conversion.  

3.1.1 Timing. In the event no Qualified Financing (as defined below) occurs prior to the earlier of (a) the closing of the sale of
shares of Common Stock to the public in a firm-commitment underwritten public offering pursuant to an effective registration statement under the Securities Act of 1933, as amended (a “Public Offering”), (b) a Deemed Liquidation
Event or (c) December 15, 2021 (the time of such closing or event, the “Optional Conversion Time”), (i) any holder of Preferred Stock shall have the right to convert all or any portion of the Preferred Stock held by
such holder into shares of Common Stock, at the applicable ratio described in Section 3.1.2 as the same may be adjusted from time to time in accordance with this Section 3 and (ii) such shares
may not be reissued by the Corporation. 
 3.1.2 Ratio. At any Optional Conversion Time, each share of Preferred Stock shall be
convertible, without the payment of additional consideration by the holder thereof, into such number of fully paid and nonassessable shares of Common Stock as is determined by dividing the Original Issue Price for each share of Preferred Stock by
the Conversion Price for each share of Preferred Stock in effect at the time of conversion. The “Conversion Price” for each share of Preferred Stock means the Original Issue Price for each share of Preferred Stock, which
initial Conversion Price, and the rate at which shares of Preferred Stock may be converted into shares of Common Stock, is subject to adjustment as provided in this Certificate of Incorporation.

32. 








 3.1.3 Notwithstanding any other provision hereof; if a conversion of Preferred Stock is to be
made in connection with a Public Offering or a Deemed Liquidation Event, the conversion of any share of Preferred Stock may, at the election of the holder thereof, be conditioned upon the consummation of such transaction, in which case such
conversion shall not be deemed to be effective until such transaction has been consummated. 
 3.2 Fractional Shares. No fractional
shares of Common Stock will be issued upon conversion of the Preferred Stock. In lieu of any fractional shares to which the holder would otherwise be entitled, the Corporation shall pay cash equal to such fraction multiplied by the fair market value
of a share of Common Stock as determined in good faith by the Board; provided, however, if any holder of Preferred Stock objects to such valuation in writing prior to such payment, the Corporation will engage an independent appraiser
experienced in valuing securities jointly selected by the Corporation and such stockholder. Whether or not fractional shares would be issuable upon such conversion will be determined on the basis of the total number of shares of Preferred Stock the
holder is at the time converting into Common Stock and the aggregate number of shares of Common Stock issuable upon such conversion. 
 3.3
Mechanics of Conversion. 
 3.3.1 Surrender of Certificates. The Corporation shall notify in writing all holders of record of
shares of Preferred Stock of the Optional Conversion Time and the place designated for optional conversion of shares of Preferred Stock pursuant to Section 3.1.1. If the Corporation obtains knowledge that a Public Offering
or a Deemed Liquidation Event is proposed to occur, the Corporation shall give prompt written notice of such event describing in reasonable detail the material terms and date of consummation thereof to each holder of Preferred Stock, but in any
event such notice shall not be given no later than five days prior to the occurrence of such Public Offering or Deemed Liquidation Event. Upon receipt of the notice, each holder of shares of Preferred Stock electing to convert all or any portion of
such holder’s Preferred Stock shall surrender such holder’s certificate or certificates for all such shares being converted (or, if such holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit
and agreement reasonably acceptable to the Corporation to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of such certificate) to the Corporation at the place
designated in such notice, and shall thereafter receive certificates for the number of shares of Common Stock to which such holder is entitled pursuant to this Section 3. If so required by the Corporation, certificates
surrendered for conversion shall be endorsed or accompanied by written instrument or instruments of transfer, in form reasonably satisfactory to the Corporation, duly executed by the registered holder or such holder’s attorney duly authorized
in writing. Other than the rights to dividend payments set forth in Section 3.3.2 below, all rights with respect to the Preferred Stock converted pursuant to Section 3.1.1, including the rights, if
any, to receive notices and vote (other than as a holder of Common Stock), will terminate at the Optional Conversion Time (notwithstanding the failure of the holder or holders thereof to surrender the certificates at or prior to such time), except
only the rights of 

  
 [*] = Certain confidential information
contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule 406 of the Securities Act of 1933, as amended. 

33. 








 
the holders thereof, upon surrender of their certificate or certificates (or lost certificate affidavit and agreement) therefor, to receive the items provided for in the next sentence of this
Section 3.3.1. As soon as practicable after the Optional Conversion Time and the surrender of the certificate or certificates (or lost certificate affidavit and agreement) for Preferred Stock, the Corporation shall issue
and deliver to such holder, or to such holder’s nominee(s), a certificate or certificates for the number of full shares of Common Stock issuable on such conversion in accordance with the provisions hereof, together with cash as provided in
Section 3.2 in lieu of any fraction of a share of Common Stock otherwise issuable upon such conversion and the payment of any declared but unpaid dividends on the shares of Preferred Stock converted. Such converted
Preferred Stock shall be retired and cancelled and may not be reissued as shares of such series, and the Corporation may thereafter take such appropriate action (without the need for stockholder action) as may be necessary to reduce the authorized
number of shares of Preferred Stock (and the applicable series thereof) accordingly. 
 3.3.2 Effect of Conversion. All shares of
Preferred Stock that shall have been surrendered for conversion as provided in this Certificate of Incorporation shall no longer be deemed to be outstanding and all rights with respect to such shares will immediately cease and terminate at the
Optional Conversion Time, except only the right of the holders thereof to receive shares of Common Stock in exchange therefor, to receive payment in lieu of any fraction of a share otherwise issuable upon such conversion as provided in
Section 3.2, and to receive payment of any unpaid dividends thereon. Any shares of Preferred Stock so converted shall be retired and cancelled and may not be reissued. 

3.3.3 No Further Adjustment. Upon any conversion of shares of Preferred Stock, no adjustment to the Conversion Price of the applicable
series of Preferred Stock will be made with respect to the converted shares for any declared but unpaid dividends on such series of Preferred Stock or on the Common Stock delivered upon conversion. 

3.4 Adjustments to Series A Conversion Price for Diluting Issues. 

3.4.1 Special Definitions. For purposes of this Article VT, the following definitions shall apply: 

(a) “Option” shall mean rights, options or warrants to subscribe for, purchase or otherwise acquire Common Stock or
Convertible Securities. 
 (b) “Series A Original Issue Date” shall mean the date on which the first share of Series
A Preferred Stock was issued. 
 (c) “Convertible Securities” shall mean any evidences of indebtedness, shares or
other securities directly or indirectly convertible into or exchangeable for Common Stock, but excluding Options. 

  
 [*] = Certain confidential information
contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule 406 of the Securities Act of 1933, as amended. 

34. 








 (d) “Additional Shares of Common Stock” shall mean all shares of Common
Stock issued (or, pursuant to Subsection 3.4.3 below, deemed to be issued) by the Corporation after the Series A Original Issue Date, other than (1) the following shares of Common Stock and (2) shares of Common Stock deemed issued
pursuant to the following Options and Convertible Securities (clauses (1) and (2), collectively, “Exempted Securities”)1: 

(i) shares of Common Stock, Options or Convertible Securities issued as a dividend or distribution on Series A Preferred Stock; 

(ii) shares of Common Stock, Options or Convertible Securities issued by reason of a dividend, stock split,
split-up or other distribution on shares of Common Stock that is covered by this Section 3; 

(iii) shares of Common Stock or Options issued to employees or directors of, or consultants or advisors to the Corporation or any of its
subsidiaries pursuant to a plan, agreement or arrangement approved by the Board of Directors of the Corporation; 
 (iv) shares of Common
Stock or Convertible Securities actually issued upon the exercise of Options or shares of Common Stock actually issued upon the conversion or exchange of Convertible Securities, in each case provided such issuance is pursuant to the terms of such
Option or Convertible Security; 
 (v) shares of Common Stock, Options or Convertible Securities issued to banks, equipment lessors or other
financial institutions, or to real property lessors, pursuant to a debt financing, equipment leasing or real property leasing transaction approved by the Board of Directors of the Corporation; 

(vi) shares of Common Stock, Options or Convertible Securities issued to suppliers or third party service providers in connection with the
provision of goods or services pursuant to transactions approved by the Board of Directors of the Corporation; or 
 (vii) shares of Common
Stock, Options or Convertible Securities issued pursuant to the acquisition of another corporation by the Corporation by merger, purchase of substantially all of the assets or other reorganization or to a joint venture agreement, provided that such
issuances are approved by the Board of Directors of the Corporation. 
 3.4.2 No Adjustment of Series A Conversion Price. No
adjustment in the Series A Conversion Price shall be made as the result of the issuance or deemed issuance of Additional Shares of Common Stock if the Corporation receives written notice from the Requisite Investors agreeing that no such adjustment
shall be made as the result of the issuance or deemed issuance of such Additional Shares of Common Stock.

35. 








 3.4.3 Deemed Issue of Additional Shares of Common Stock. 

(a) If the Corporation at any time or from time to time after the Series A Original Issue Date shall issue any Options or Convertible
Securities (excluding Options or Convertible Securities which are themselves Exempted Securities) or shall fix a record date for the determination of holders of any class of securities entitled to receive any such Options or Convertible Securities,
then the maximum number of shares of Common Stock (as set forth in the instrument relating thereto, assuming the satisfaction of any conditions to exercisability, convertibility or exchangeability but without regard to any provision contained
therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be
Additional Shares of Common Stock issued as of the time of such issue or, in case such a record date shall have been fixed, as of the close of business on such record date. 

(b) If the terms of any Option or Convertible Security, the issuance of which resulted in an adjustment to the Series A Conversion Price
pursuant to the terms of Subsection 3.4.4, are revised as a result of an amendment to such terms or any other adjustment pursuant to the provisions of such Option or Convertible Security (but excluding automatic adjustments to such terms
pursuant to anti-dilution or similar provisions of such Option or Convertible Security) to provide for either (1) any increase or decrease in the number of shares of Common Stock issuable upon the exercise, conversion and/or exchange of any
such Option or Convertible Security or (2) any increase or decrease in the consideration payable to the Corporation upon such exercise, conversion and/or exchange, then, effective upon such increase or decrease becoming effective, the Series A
Conversion Price computed upon the original issue of such Option or Convertible Security (or upon the occurrence of a record date with respect thereto) shall be readjusted to such Series A Conversion Price as would have obtained had such revised
terms been in effect upon the original date of issuance of such Option or Convertible Security. Notwithstanding the foregoing, no readjustment pursuant to this clause (b) shall have the effect of increasing the Series A Conversion Price to an
amount which exceeds the lower of (i) the Series A Conversion Price in effect immediately prior to the original adjustment made as a result of the issuance of such Option or Convertible Security, and (ii) the Series A Conversion Price that
would have resulted from any issuances of Additional Shares of Common Stock (other than deemed issuances of Additional Shares of Common Stock as a result of the issuance of such Option or Convertible Security) between the original adjustment date
and such readjustment date. 
 (c) If the terms of any Option or Convertible Security (excluding Options or Convertible Securities which are
themselves Exempted Securities), the issuance of which did not result in an adjustment to the Series A Conversion Price pursuant to the terms of Subsection 3.4.4 (either because the consideration per share (determined pursuant to
Subsection 3.4.5) of the Additional Shares of Common Stock subject thereto was equal to or greater than the Series A Conversion Price then in effect, or because such Option or Convertible Security was issued before the Series A Original Issue
Date), are revised after the Series A Original Issue Date as a result of an amendment to such terms or any other adjustment pursuant to the provisions of such Option or Convertible Security (but excluding automatic adjustments to such terms pursuant
to anti-dilution or similar provisions of such Option or Convertible Security) to provide for either (1) any increase in the number of shares of Common Stock issuable upon the exercise, conversion or exchange of any such Option or Convertible
Security or (2) any decrease in the consideration payable to the Corporation upon such exercise, conversion or exchange, then such Option or Convertible Security, as so amended or adjusted, and the Additional Shares of Common Stock subject
thereto (determined in the manner provided in Subsection 3.4.3(a)) shall be deemed to have been issued effective upon such increase or decrease becoming effective. 

  
 [*] = Certain confidential information

36. 








 (d) Upon the expiration or termination of any unexercised Option or unconverted or unexchanged
Convertible Security (or portion thereof) which resulted (either upon its original issuance or upon a revision of its terms) in an adjustment to the Series A Conversion Price pursuant to the terms of Subsection 3.4.4, the Series A Conversion
Price shall be readjusted to such Series A Conversion Price as would have obtained had such Option or Convertible Security (or portion thereof) never been issued. 

(e) If the number of shares of Common Stock issuable upon the exercise, conversion and/or exchange of any Option or Convertible Security, or
the consideration payable to the Corporation upon such exercise, conversion and/or exchange, is calculable at the time such Option or Convertible Security is issued or amended but is subject to adjustment based upon subsequent events, any adjustment
to the Series A Conversion Price provided for in this Subsection 3.4.3 shall be effected at the time of such issuance or amendment based on such number of shares or amount of consideration without regard to any provisions for subsequent
adjustments (and any subsequent adjustments shall be treated as provided in clauses (b) and (c) of this Subsection 3.4.3). If the number of shares of Common Stock issuable upon the exercise, conversion and/or exchange of any Option or
Convertible Security, or the consideration payable to the Corporation upon such exercise, conversion and/or exchange, cannot be calculated at all at the time such Option or Convertible Security is issued or amended, any adjustment to the Series A
Conversion Price that would result under the terms of this Subsection 3.4.3 at the time of such issuance or amendment shall instead be effected at the time such number of shares and/or amount of consideration is first calculable (even if
subject to subsequent adjustments), assuming for purposes of calculating such adjustment to the Series A Conversion Price that such issuance or amendment took place at the time such calculation can first be made. 

3.4.4 Adjustment of Series A Conversion Price Upon Issuance of Additional Shares of Common Stock. In the event the Corporation shall at
any time after the Series A Original Issue Date issue Additional Shares of Common Stock (including Additional Shares of Common Stock deemed to be issued pursuant to Subsection 3.4.3), without consideration or for a consideration per share less than
the Series A Conversion Price in effect immediately prior to such issue, then the Series A Conversion Price shall be reduced, concurrently with such issue, to a price (calculated to the nearest one-hundredth
of a cent) determined in accordance with the following formula: 
 CP2 = CP1* (A + B) (A + C). 
 (a)
CP2” shall mean the Series A Conversion Price in effect immediately after such issue of Additional Shares of Common Stock. 

(b) “CP1” shall mean the Series A Conversion Price in effect immediately
prior to such issue of Additional Shares of Common Stock;

contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule 406 of the Securities Act of 1933, as amended. 

37. 








 (c) “A” shall mean the number of shares of Common Stock outstanding immediately prior
to such issue of Additional Shares of Common Stock (treating for this purpose as outstanding all shares of Common Stock issuable upon exercise of Options outstanding immediately prior to such issue or upon conversion or exchange of Convertible
Securities (including the Series A Preferred Stock) outstanding (assuming exercise of any outstanding Options therefor) immediately prior to such issue); 

(d) “B” shall mean the number of shares of Common Stock that would have been issued if such Additional Shares of Common Stock had
been issued at a price per share equal to CPI (determined by dividing the aggregate consideration received by the Corporation in respect of such issue by CPI); and 

(e) “C” shall mean the number of such Additional Shares of Common Stock issued in such transaction. 

3.4.5 Determination of Consideration. For purposes of this Subsection 3.4, the consideration received by the Corporation for the
issue of any Additional Shares of Common Stock shall be computed as follows: 
 (a) Cash and Property: Such consideration shall: 

(i) insofar as it consists of cash, be computed at the aggregate amount of cash received by the Corporation, excluding amounts paid or payable
for accrued interest; 
 (ii) insofar as it consists of property other than cash, be computed at the fair market value thereof at the time
of such issue, as determined in good faith by the Board of Directors of the Corporation; provided, however, if any holder of Preferred Stock objects to such valuation in writing, the Corporation will engage an independent appraiser
experienced in valuing such property jointly selected by the Corporation and such objecting stockholder; and 
 (iii) in the event
Additional Shares of Common Stock are issued together with other shares or securities or other assets of the Corporation for consideration which covers both, be the proportion of such consideration so received, computed as provided in clauses
(i) and (ii) above, as determined in good faith by the Board of Directors of the Corporation; provided, however, if any holder of Preferred Stock objects to such valuation in writing, the Corporation will engage an independent
appraiser experienced in valuing securities jointly selected by the Corporation and such objecting stockholder.

contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule 406 of the Securities Act of 1933, as amended. 

38. 








 (b) Options and Convertible Securities. The consideration per share received by the
Corporation for Additional Shares of Common Stock deemed to have been issued pursuant to Subsection 3.4.3, relating to Options and Convertible Securities, shall be determined by dividing 

(i) the total amount, if any, received or receivable by the Corporation as consideration for the issue of such Options or Convertible
Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to the
Corporation upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange
of such Convertible Securities, by 
 (ii) the maximum number of shares of Common Stock (as set forth in the instruments relating thereto,
without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible
Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities. 
 3.4.6
Multiple Closing Dates. In the event the Corporation shall issue on more than one date Additional Shares of Common Stock that are a part of one transaction or a series of related transactions and that would result in an adjustment to the
Series A Conversion Price pursuant to the terms of Subsection 3.4.4, and such issuance dates occur within a period of no more than 90 days from the first such issuance to the final such issuance, then, upon the final such issuance, the Series
A Conversion Price shall be readjusted to give effect to all such issuances as if they occurred on the date of the first such issuance (and without giving effect to any additional adjustments as a result of any such subsequent issuances within such
period). 
 3.5 Adjustment for Stock Splits and Combinations. If the Corporation at any time or from time to time after the date on
which the first share of a series of Preferred Stock is issued by the Corporation (such date referred to herein as the “Original Issue Date” for such series of Preferred Stock) effects a subdivision of the outstanding Common
Stock, the Conversion Price for each series of Preferred Stock in effect immediately before that subdivision shall be proportionately decreased so that the number of shares of Common Stock issuable on conversion of each share of that series will be
increased in proportion to the increase in the aggregate number of shares of Common Stock outstanding. If the Corporation at any time or from time to time after the Original Issue Date for a series of Preferred Stock combines the outstanding shares
of Common Stock, the Conversion Price for each series of Preferred Stock in effect immediately before the combination will be proportionately increased so that the number of shares of Common Stock issuable on conversion of each share of such series
shall be decreased in proportion to such decrease in the aggregate number of shares of Common Stock outstanding. Any adjustment under this Section 3.4 becomes effective at the close of business on the date the subdivision
or combination becomes effective.

39. 








 3.6 Adjustment for Certain Dividends and Distributions. If the Corporation at any time or
from time to time after the Original Issue Date for a series of Preferred Stock makes or issues, or fixes a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable on the Common
Stock in additional shares of Common Stock, then and in each such event the Conversion Price for such series of Preferred Stock in effect immediately before the event will be decreased as of the time of such issuance or, in the event a record date
has been fixed, as of the close of business on such record date, by multiplying such Conversion Price then in effect by a fraction: 
 (a)
the numerator of which is the total number of shares of Common Stock issued and outstanding immediately prior to the time of the issuance or the close of business on the record date, and 

(b) the denominator of which is the total number of shares of Common Stock issued and outstanding immediately before the time of such issuance
or the close of business on the record date plus the number of shares of Common Stock issuable in payment of such dividend or distribution. 

Notwithstanding the foregoing, (i) if such record date has have been fixed and the dividend is not fully paid or if such distribution is not fully made
on the date fixed therefor, such Conversion Price shall be recomputed accordingly as of the close of business on such record date and thereafter such Conversion Price shall be adjusted pursuant to this Section 3.5 as of the
time of actual payment of such dividends or distributions; and (ii) no such adjustment shall be made if the holders of such series of Preferred Stock simultaneously receive a dividend or other distribution of shares of Common Stock in a number
equal to the number of shares of Common Stock that they would have received if all outstanding shares of such series of Preferred Stock had been converted into Common Stock on the date of the event. 

3.7 Adjustments for Other Dividends and Distributions. If the Corporation at any time or from time to time after the Original Issue Date
for a series of Preferred Stock shall makes or issues, or fixes a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of the Corporation (other than a distribution
of shares of Common Stock in respect of outstanding shares of Common Stock), then and in each such event the Corporation shall make, simultaneously with the distribution to the holders of Common Stock, a dividend or other distribution to the holders
of the series of Preferred Stock in an amount equal to the amount of securities as the holders would have received if all outstanding shares of such series of Preferred Stock had been converted into Common Stock on the date of such event. 

3.8 Adjustment for Reclassification, Exchange and Substitution. If at any time or from time to time after the Original Issue Date for a
series of Preferred Stock the Common Stock issuable upon the conversion of such series of Preferred Stock is changed into the same or a different number of shares of any class or classes of stock of the Corporation, whether by recapitalization,
reclassification, or otherwise (other than by a stock split or combination, dividend, distribution, merger or consolidation covered by Sections 3.4, 3.5, 3.6 or 3.8 or by
Section 1.3 regarding a Deemed Liquidation Event), then in any such event each holder of such series of Preferred Stock may thereafter convert such stock into the kind and amount of stock and other securities and property
receivable upon such recapitalization, reclassification or other change by holders of the number of shares of Common Stock into which such shares of Preferred Stock could have been converted immediately prior to such recapitalization,
reclassification or change.

40. 








 3.9 Adjustment for Merger or Consolidation. Subject to the provisions of
Section 1.3, if any consolidation or merger occurs involving the Corporation in which the Common Stock (but not a series of Preferred Stock) is converted into or exchanged for securities, cash, or other property (other than
a transaction covered by Sections 3.5, 3.6 or 3.7), then, following any such consolidation or merger, the Corporation shall provide that each share of such series of Preferred Stock will thereafter be convertible, in lieu of the
Common Stock into which it was convertible prior to the event, into the kind and amount of securities, cash, or other property which a holder of the number of shares of Common Stock of the Corporation issuable upon conversion of one share of such
series of Preferred Stock immediately prior to the consolidation or merger would have been entitled to receive pursuant to the transaction; and, in such case, the Corporation shall make appropriate adjustment (as determined in good faith by the
Board) in the application of the provisions in this Section 3 with respect to the rights and interests thereafter of the holders of such series of Preferred Stock, to the end that the provisions set forth in this
Section 3 (including provisions with respect to changes in and other adjustments of the Conversion Price of such series of Preferred Stock) shall thereafter be applicable, as nearly as reasonably may be, in relation to any
securities or other property thereafter deliverable upon the conversion of such series of Preferred Stock. 
 3.10 Conversion Into
Qualified Financing Preferred Stock. At the time of the closing of the Qualified Financing (as defined below), the then outstanding Series A Preferred Stock plus any accrued but unpaid dividends due and payable up through the Qualified Financing
Conversion Date shall be converted into fully paid and nonassessable shares of Qualified Financing Preferred Stock (as defined below). The holders of Series A Preferred Stock, upon such conversion, will be entitled to receive that number of whole
shares of Qualified Financing Preferred Stock as shall be equal to the Original Issue Price of each share of Series A Preferred Stock plus any accrued but unpaid dividends thereon, as of the Qualified Financing Conversion Date (as defined
below), could purchase at ninety percent (90%) of the price per share of the Qualified Financing Preferred Stock; provided that if a Qualified Financing involves more than one sale by the Corporation of new equity securities, the “price per
share of the Qualified Financing Preferred Stock” contemplated by this sentence shall mean the lowest price per share of the Qualified Financing Preferred Stock offered in such sales (as equitably adjusted for any stock splits and stock
dividends). “Qualified Financing” shall mean the sale (or a series of sales) by the Corporation of new equity securities, which sale (or series of sales) results in proceeds to the Corporation of an aggregate amount of at
least $7,500,000, excluding the value of the Series A Preferred Stock being converted. “Qualified Financing Conversion Date” shall mean any date on which the then outstanding shares of Series A Preferred Stock shall be
converted into shares of Qualified Financing Preferred Stock. “Qualified Financing Preferred Stock” means shares of a series of new equity securities to be authorized and sold by the Corporation to investors in the Qualified
Financing.

41. 








 4. Dividends. From and after the date of the issuance of any shares of Series A
Preferred Stock, dividends at the rate of five percent (5%) of the Series A Original Issue Price per share of Series A Preferred Stock per annum shall accrue on such shares of Series A Preferred Stock (subject to appropriate adjustment in the event
of any stock dividend, stock split, combination or other similar recapitalization with respect to the Series A Preferred Stock) (the “Accruing Dividends”). Accruing Dividends shall accrue from day to day, whether or not
declared, and shall be cumulative; provided, however, that except as set forth in the following sentence of this Section 4, Subsection 1.1, and Subsection 3.3.2 such Accruing Dividends shall be
payable only when, as, and if (a) declared by the Board of Directors or (b) upon the Conversion of the Series A Preferred Stock into Common Stock pursuant to Subsection 3.1 or (c) upon the Conversion of the Series A Preferred
Stock into Qualified Financing Preferred Stock pursuant to Subsection 3.10 and the Corporation shall not otherwise be under any obligation to pay such Accruing Dividends. The Corporation shall not declare, pay or set aside any dividends on
shares of any other class or series of capital stock of the Corporation (other than dividends on shares of Common Stock payable in shares of Common Stock) unless (in addition to the obtaining of any consents required elsewhere in the Certificate of
Incorporation) the holders of the Series A Preferred Stock then outstanding shall first receive, or simultaneously receive, a dividend on each outstanding share of Series A Preferred Stock in an amount at least equal to the greater of (i) the
amount of the aggregate Accruing Dividends then accrued on such share of Series A Preferred Stock and not previously paid and (ii) (A) in the case of a dividend on Common Stock or any class or series that is convertible into Common Stock, that
dividend per share of Series A Preferred Stock as would equal the product of (1) the dividend payable on each share of such class or series determined, if applicable, as if all shares of such class or series had been converted into Common Stock
and (2) the number of shares of Common Stock issuable upon conversion of a share of Series A Preferred Stock, in each case calculated on the record date for determination of holders entitled to receive such dividend or (B) in the case of a
dividend on any class or series that is not convertible into Common Stock, at a rate per share of Series A Preferred Stock determined by (1) dividing the amount of the dividend payable on each share of such class or series of capital stock by
the original issuance price of such class or series of capital stock (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to such class or series) and
(2) multiplying such fraction by an amount equal to the Series A Original Issue Price (as defined below); provided that if the Corporation declares, pays or sets aside, on the same date, a dividend on shares of more than one class or
series of capital stock of the Corporation, the dividend payable to the holders of Series A Preferred Stock pursuant to this Section 4 shall be calculated based upon the dividend on the class or series of capital stock that
would result in the highest Series A Preferred Stock dividend. 
 5. Special Redemptions. 

5.1 If a Deemed Liquidation Event is proposed to occur, the Corporation shall give prompt written notice of such Deemed Liquidation Event
describing in reasonable detail the material terms and date of consummation thereof to each holder of Preferred Stock, but in any event such notice shall not be given later than five days prior to the occurrence of such Deemed Liquidation Event, and
the Corporation shall give each holder of Preferred Stock prompt written notice of any material change in the terms or timing of such transaction. Any holder of Preferred Stock may require the Corporation to redeem all or any portion of the
Preferred Stock owned by such holder at a price per share equal to the Original Issue Price thereof (plus all accrued and unpaid dividends thereon) by giving written notice to the Corporation of such election prior to the later of (a) 21 days after
receipt of the Corporation’s notice and (b) five days prior to the

42. 








 
consummation of the Deemed Liquidation Event (the “Expiration Date”). The Corporation shall give prompt written notice of any such election to all other holders of Preferred Stock
within five days after the receipt thereof, and each such holder shall have until the later of (a) the Expiration Date and (b) ten days after receipt of such second notice to request redemption hereunder (by giving written notice to the
Corporation) of all or any portion of the Preferred Stock owned by such holder. 
 5.2 Upon receipt of such election(s), the Corporation
shall be obligated to redeem the aggregate number of shares of Preferred Stock specified therein on the occurrence of the Deemed Liquidation Event. If any proposed Deemed Liquidation Event does not occur, alt requests for redemption in connection
therewith shall be automatically rescinded, or if there has been a material change in the terms or the timing of the transaction, any holder of Preferred Stock may rescind such holder’s request for redemption by giving written notice of such
rescission to the Corporation. If the Corporation does not have sufficient funds legally available to redeem all shares of Preferred Stock on the occurrence of the Deemed Liquidation Event, the Corporation shall redeem a pro rata portion of each
holder’s shares out of funds legally available therefor, based on the respective amounts which would otherwise be payable in respect of the shares to be redeemed if the legally available funds were sufficient to redeem all such shares, and
shall redeem the remaining shares to have been redeemed as soon as practicable after the Corporation has funds legally available therefor. 

6. Redeemed or Otherwise Acquired Shares. Any shares of Preferred Stock that are redeemed or otherwise acquired by the
Corporation or any of its subsidiaries will be automatically and immediately cancelled and retired and shall not be reissued, sold or transferred. Neither the Corporation nor any of its subsidiaries may exercise any voting or other rights granted to
the holders of Preferred Stock following any such redemption. 
 7. Waiver. Any of the rights, powers, privileges
and other terms of the Preferred Stock set forth herein may be waived prospectively or retrospectively on behalf of all holders of Preferred Stock by the affirmative written consent or vote of the holders of the Requisite Holders. 

8. Notice of Record Date. In the event: 

(a) the Corporation takes a record of the holders of its Common Stock (or other capital stock or securities at the time issuable upon
conversion of the Preferred Stock) for the purpose of entitling or enabling them to receive any dividend or other distribution, or to receive any right to subscribe for or purchase any shares of capital stock of any class or any other securities, or
to receive any other security; or 
 (b) of any capital reorganization of the Corporation, any reclassification of the Common Stock of the
Corporation, or any Deemed Liquidation Event; or 
 (c) of the voluntary or involuntary dissolution, liquidation or winding-up of the Corporation,

43. 








 then, and in each such case, the Corporation shall send or cause to be sent to the holders of the Preferred Stock
a written notice specifying, as the case may be, (i) the record date for such dividend, distribution, or right, and the amount and character of such dividend, distribution or right, or (ii) the effective date on which such reorganization,
reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up is proposed to take place, and the time, if any is to be fixed, as of which the holders of record of Common Stock (or
such other capital stock or securities at the time issuable upon the conversion of the Preferred Stock) will be entitled to exchange their shares of Common Stock (or such other capital stock or securities) for securities or other property
deliverable upon such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up, and the amount per share and character of such exchange applicable to the
Preferred Stock and the Common Stock. The Corporation shall send the notice at least 20 days before the earlier of the record date or effective date for the event specified in the notice. 

8. Notices. Except as otherwise provided herein, any notice required or permitted by the provisions of this Article
VI to be given to a holder of shares of Preferred Stock must be mailed, postage prepaid, to the post office address last shown on the records of the Corporation, or given by electronic communication in compliance with the provisions of the General
Corporation Law, and will be deemed sent upon such mailing or electronic transmission. 
 ARTICLE VII: PREEMPTIVE RIGHTS.

 No stockholder of the Corporation has a right to purchase shares of capital stock of the Corporation sold or issued by the
Corporation except to the extent that such a right may from time to time be set forth in a written agreement between the Corporation and the stockholder. 

ARTICLE VIII: BYLAW PROVISIONS. 

A. AMENDMENT OF BYLAWS. Subject to any additional vote required by this Certificate of Incorporation or bylaws of the Corporation (the
“Bylaws”), in furtherance and not in limitation of the powers conferred by statute, the Board is expressly authorized to make, repeal, alter, amend and rescind any or all of the Bylaws.
