2.    Voting. The holders of the Common Stock are entitled to one vote for each share of Common Stock held at all

 B.    PREFERRED STOCK 

51,310,614 shares of the authorized Preferred Stock are hereby designated “Series A Preferred Stock,” 948,225 shares of the
authorized Preferred Stock are hereby designated “Series A Prime Preferred Stock” and 42,149,628 shares of the authorized Preferred Stock are hereby designated “Series B Preferred Stock.” The Preferred Stock shall
have the following rights, preferences, powers, privileges and restrictions, qualifications and limitations. Unless otherwise indicated, references to “sections” or “subsections” in this Part B of this Article Fourth refer to
sections and subsections of Part B of this Article Fourth. 
 1.    Liquidation, Dissolution or Winding Up; Certain
Mergers, Consolidations and Asset Sales. 
 1.1    Preferential Payments to Holders of Preferred Stock. In
the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation or Deemed Liquidation Event, the holders of shares of Preferred Stock then outstanding shall be entitled to be paid out of the assets of the
Corporation available for distribution to its stockholders before any payment shall be made to the holders of Common Stock by reason of their ownership thereof, an amount per share equal to the greater of (i) the applicable Original Issue Price
(as defined below), or (ii) such amount per share as would have been payable had all shares of such series of Preferred Stock been converted into Common Stock pursuant to Section 3 immediately prior to such
liquidation, dissolution, winding up or Deemed Liquidation Event (the amount payable pursuant to this sentence is hereinafter referred to as the “Liquidation Amount”). If upon any such liquidation, dissolution or winding up of the
Corporation or Deemed Liquidation Event, the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the holders of shares of Series A Preferred Stock the full amount to which they shall be entitled
under this Subsection 1.1, the holders of shares of Series A Preferred Stock shall share ratably in any distribution of the assets available for distribution in proportion to the respective amounts which would otherwise be
payable in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full. The “Series A Original Issue Price” shall mean $1.147 per share,
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 “Series A Prime Original Issue Price”
shall mean $2.294 per share, 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 “Series B Original Issue
Price” shall mean $2.0878 per share, 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 Series A Original Issue
Price, the Series A Prime Original Issue Price and the Series B Original Issue Price shall each be referred to as an “Original Issue Price.” 

1.2    Payments to Holders of Common Stock. In the event of any voluntary or involuntary liquidation, dissolution
or winding up of the Corporation or Deemed Liquidation Event, after the payment of all preferential amounts required to be paid to the holders of shares of Preferred Stock, the remaining assets of the Corporation available for distribution to its
stockholders shall be distributed among the holders of shares of Common Stock, pro rata based on the number of shares held by each such holder.

 1.3    Deemed Liquidation Events. 

1.3.1    Definition. Each of the following events shall be considered a “Deemed Liquidation
Event” unless the holders of a majority of the outstanding shares of Preferred Stock, voting together as a single class and on an as-converted basis (the “Requisite Majority”), elect
otherwise by written notice sent to the Corporation at least 10 days prior to the effective date of any such event: 

(a)    a merger or consolidation in which 
  

	 	(i)	 the Corporation is a constituent party or 



 

	 	(ii)	 a subsidiary of the Corporation is a constituent party and the Corporation issues shares of its capital stock
pursuant to such merger or consolidation, 


 except any such merger or consolidation involving the Corporation or a subsidiary in which
the shares of capital stock of the Corporation outstanding immediately prior to such merger or consolidation continue to represent, or are converted into or exchanged for shares of capital stock that represent, immediately following such merger or
consolidation, a majority, by voting power, of the capital stock of (1) the surviving or resulting corporation; or (2) if the surviving or resulting corporation is a wholly owned subsidiary of another corporation immediately following such
merger or consolidation, the parent corporation of such surviving or resulting corporation; or 
 (b)    the sale,
lease, transfer, exclusive license or other disposition, in a single transaction or series of related transactions, by the Corporation or any subsidiary of the Corporation of all or substantially all the assets of the Corporation and its
subsidiaries taken as a whole, or the sale or disposition (whether by merger, consolidation or otherwise) of one or more subsidiaries of the Corporation if substantially all of the assets of the Corporation and its subsidiaries taken as a whole are
held by such subsidiary or subsidiaries, except where such sale, lease, transfer, exclusive license or other disposition is to a wholly owned subsidiary of the Corporation. 

1.3.2    Effecting a Deemed Liquidation Event. 

(a)    The Corporation shall not have the power to effect a Deemed Liquidation Event referred to in Subsection
1.3.1(a)(i) unless the agreement or plan of merger or consolidation for such transaction (the “Merger Agreement”) provides that the consideration payable to the stockholders of the Corporation shall be
allocated among the holders of capital stock of the Corporation in accordance with Subsections 1.1 and 1.2. 

  
 3 













 (b)    In the event of a Deemed Liquidation Event referred to in
Subsection 1.3.1(a)(ii) or 1.3.1(b), if the Corporation does not effect a dissolution of the Corporation under the General Corporation Law within ninety (90) days after such Deemed Liquidation Event, then (i) the Corporation
shall send a written notice to each holder of Preferred Stock no later than the ninetieth (90th) day after the Deemed Liquidation Event advising such holders of their right (and the requirements
to be met to secure such right) pursuant to the terms of the following clause (ii) to require the redemption of such shares of Preferred Stock, and (ii) if the Requisite Majority so request in a written instrument delivered to the
Corporation not later than one hundred twenty (120) days after such Deemed Liquidation Event, the Corporation shall use the consideration received by the Corporation for such Deemed Liquidation Event (net of any retained liabilities associated
with the assets sold or technology licensed, as determined in good faith by the Board of Directors of the Corporation (the “Board”)), together with any other assets of the Corporation available for distribution to its
stockholders, all to the extent permitted by Delaware law governing distributions to stockholders (the “Available Proceeds”), on the one hundred fiftieth (150th) day after
such Deemed Liquidation Event, to redeem all outstanding shares of each series of Preferred Stock at a price per share equal to the Liquidation Amount. Notwithstanding the foregoing, in the event of a redemption pursuant to the preceding sentence,
if the Available Proceeds are not sufficient to redeem all outstanding shares of Preferred Stock, the Corporation shall ratably redeem each holder’s shares of Preferred Stock to the fullest extent of such Available Proceeds, and shall redeem
the remaining shares as soon as it may lawfully do so under Delaware law governing distributions to stockholders. The provisions of Section 5 shall apply, with such necessary changes in the details thereof as are
necessitated by the context, to the redemption of the Preferred Stock pursuant to this Subsection 1.3.2(b). Prior to the distribution or redemption provided for in this Subsection 1.3.2(b), the Corporation shall not expend or dissipate
the consideration received for such Deemed Liquidation Event, except to discharge expenses incurred in connection with such Deemed Liquidation Event or in the ordinary course of business. 

1.3.3    Amount Deemed Paid or Distributed. The amount deemed paid or distributed to the holders of capital stock
of the Corporation upon any such merger, consolidation, sale, transfer, exclusive license, other disposition or redemption shall 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. 

1.3.4    Allocation of Escrow and Contingent Consideration. In the event of a Deemed Liquidation Event pursuant to
Subsection 1.3.1(a)(i), if any portion of the consideration payable to the stockholders of the Corporation is payable only upon satisfaction of contingencies (the “Additional Consideration”), the Merger
Agreement shall provide that (a) the portion of such consideration that is not Additional Consideration (such portion, the “Initial Consideration”) shall be allocated among the holders of capital stock of the Corporation in
accordance with Subsections 1.1 and 1.2 as if the Initial Consideration were the only consideration payable in connection with such Deemed Liquidation Event; and (b) any Additional Consideration which becomes payable to the
stockholders of the Corporation upon satisfaction of such contingencies shall be allocated among the holders of capital stock of the Corporation in accordance with Subsections 1.1 and 1.2 after taking into account the previous


  
 4 













 
payment of the Initial Consideration as part of the same transaction. For the purposes of this Subsection 1.3.4, consideration placed into escrow or retained as holdback to be available
for satisfaction of indemnification or similar obligations in connection with such Deemed Liquidation Event shall be deemed to be Additional Consideration. 

2.    Voting. 

2.1    General. 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 shall be entitled to 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. Except as provided by law or by the other provisions of the Certificate of
Incorporation, holders of Preferred Stock shall vote together with the holders of Common Stock as a single class. 

2.2    Election of Directors. For as long as there are shares of Series A Preferred Stock outstanding, the holders
of record of the shares of Series A Preferred Stock, exclusively and as a separate class, shall be entitled to elect three directors of the Corporation (the “Series A Directors”); for so long as there are shares of Series B
Preferred Stock outstanding, the holders of record of the shares of Series B Preferred Stock, exclusively and as a separate class, shall be entitled to elect two directors of the Corporation (the “Series B Directors” and,
together with the Series A Directors, the “Preferred Directors”); and the holders of record of the shares of Common Stock, exclusively and as a separate class, shall be entitled to elect one director of the
Corporation. Any director elected as provided in the preceding sentence may be removed without cause by, and only by, the affirmative vote of the holders of the shares of the class or series of capital stock entitled to elect such director or
directors, given either at a special meeting of such stockholders duly called for that purpose or pursuant to a written consent of stockholders. If the holders of shares of Series A Preferred Stock, Series B Preferred Stock or Common Stock, as the
case may be, fail to elect a sufficient number of directors to fill all directorships for which they are entitled to elect directors, voting exclusively and as a separate class, pursuant to the first sentence of this
Subsection 2.2, then any directorship not so filled shall remain vacant until such time as the holders of the Series A Preferred Stock, Series B Preferred Stock or Common Stock, as the case may be, elect a person to fill
such directorship by vote or written consent in lieu of a meeting; and no such directorship may be filled by stockholders of the Corporation other than by the stockholders of the Corporation that are entitled to elect a person to fill such
directorship, voting exclusively and as a separate class. The holders of record of the shares of Common Stock and of any other class or series of voting stock (including the Preferred Stock), exclusively and voting together as a
single class, shall be entitled to elect the balance of the total number of directors of the Corporation. At any meeting held for the purpose of electing a director, the presence in person or by proxy of the holders of a majority of the outstanding
shares of the class or series entitled to elect such director shall constitute a quorum for the purpose of electing such director. Except as otherwise provided in this Subsection 2.2, a vacancy in any directorship
filled by the holders of any class or series shall be filled only by vote or written consent in lieu of a meeting of the holders of such class or series or by any remaining director or directors elected by the holders of such class or series
pursuant to this Subsection 2.2.

 2.3    Preferred Stock Protective Provisions. At any time when
shares of Series A Preferred Stock or Series B Preferred Stock are outstanding, the Corporation shall not, either directly or indirectly by amendment, merger, consolidation or otherwise, do any of the following without (in addition to any other vote
required by law or this Certificate of Incorporation) the written consent or affirmative vote of the Requisite Majority, given in writing or by vote at a meeting, consenting or voting (as the case may be) separately as a class, and any such act or
transaction entered into without such consent or vote shall be null and void ab initio, and of no force or effect: 

2.3.1    create, or authorize the creation of any equity securities unless the same ranks junior to the Preferred Stock
with respect to the distribution of assets on the liquidation, dissolution or winding up of the Corporation, the payment of dividends and rights of redemption, or increase the authorized number of shares of Preferred Stock or increase the authorized
number of shares of any equity securities unless the same ranks junior to the Preferred Stock with respect to the distribution of assets on the liquidation, dissolution or winding up of the Corporation, the payment of dividends and rights of
redemption; 
 2.3.2    amend, alter or repeal any provision of the Certificate of Incorporation or Bylaws of the
Corporation; 
 2.3.3    liquidate, dissolve or wind-up the business and
affairs of the Corporation, effect any Deemed Liquidation Event, effect any sale or other disposition of all or substantially all of the assets, or sale of a majority of the outstanding shares of equity interests, of any one of the
Corporation’s subsidiaries (whether, in either case, in a single transaction or series of related transactions) or consent to any of the foregoing; provided that, if the distributions per share to the holders of the Series B Preferred Stock in
connection with any such liquidation event listed in this Section 2.3.3 shall equal less than the Series B Original Issue Price, then any such event pursuant to this Section 2.3.3 (and any
amendment or waiver of this Section 2.3.3) shall require the written consent or affirmative vote of the holders of a majority of the outstanding shares of Series B Preferred Stock; 

2.3.4    (A) reclassify, alter or amend any existing security of the Corporation that is pari passu with the Preferred
Stock in respect of the distribution of assets on the liquidation, dissolution or winding up of the Corporation, the payment of dividends or rights of redemption, if such reclassification, alteration or amendment would render such other security
senior to the Preferred Stock in respect of any such right, preference, or privilege or (B) reclassify, alter or amend any existing security of the Corporation that is junior to the Preferred Stock in respect of the distribution of assets on
the liquidation, dissolution or winding up of the Corporation, the payment of dividends or rights of redemption, if such reclassification, alteration or amendment would render such other security senior to or pari passu with the Preferred Stock in
respect of any such right, preference or privilege; 

  
 6 













 2.3.5    purchase or redeem (or permit any subsidiary to purchase or
redeem) or otherwise acquire any equity securities other than (A) redemptions of or dividends or distributions on the Preferred Stock as expressly authorized herein, (B) dividends or other distributions payable on the Common Stock solely
in the form of additional shares of Common Stock or (C) repurchases of stock from former employees, officers, directors, consultants or other persons who performed services for the Corporation or any subsidiary in connection with the cessation
of such employment or service, at the lower of the original purchase price or the then-current fair market value thereof; 

2.3.6    increase or decrease the authorized number of directors constituting the Board; 

2.3.7    create, or hold equity securities in, any entity that would result in the consolidation of such entity into the
results of operations of the Corporation, or acquire all or substantially all of the assets of another entity; 

2.3.8    create, or authorize the creation of, or issue, or authorize the issuance of any debt security, or permit any
subsidiary to take any such action with respect to any debt security, if the aggregate indebtedness of the Corporation and its subsidiaries for borrowed money following such action would exceed $500,000; or 

2.3.9    create a new plan or arrangement for the grant of equity awards, or increase the number of shares available
under such a plan or arrangement, unless such plan or arrangement is approved by the Board, including a majority of the Preferred Directors. 

3.    Optional Conversion. 

The holders of the Preferred Stock shall have conversion rights as follows (the “Conversion Rights”): 

3.1    Right to Convert. 

3.1.1    Conversion Ratio. Each share of Preferred Stock shall be convertible, at the option of and without payment
of additional consideration by the holder thereof, at any time after the date of issuance of such share of Preferred Stock, into such number of fully paid and non-assessable shares of Common Stock as is
determined by dividing the applicable Original Issue Price by the applicable Conversion Price for such share of Preferred Stock (the resulting conversion rate for Preferred Stock into Common Stock is referred to herein as the “Conversion
Rate”), determined as hereafter provided, in effect on the date of conversion. The “Series A Conversion Price” shall initially be equal to $5.8490. Such initial Series A Conversion Price, and the rate at which
shares of Series A Preferred Stock may be converted into shares of Common Stock, shall be subject to adjustment as provided below. The “Series A Prime Conversion Price” shall initially be equal to $10.6465. Such
initial Series A Prime Conversion Price, and the rate at which shares of Series A Prime Preferred Stock may be converted into shares of Common Stock, shall be subject to adjustment as provided below. The “Series B Conversion Price”
shall initially be equal to $10.6465. Such initial Series B Conversion Price, and the rate at which shares of Series B Preferred Stock may be converted into shares of Common Stock, shall be subject to adjustment as provided below. 

  
 7 













 3.1.2    Termination of Conversion Rights. In the event of a
notice of redemption of any shares of Preferred Stock pursuant to Section 5, the conversion rights of the shares designated for redemption shall terminate at the close of business on the last full day preceding the date
fixed for redemption, unless the Redemption Price (as defined below) is not fully paid on such Redemption Date (as defined below), in which case the conversion rights for such shares shall continue until such price is paid in full. In the event of a
liquidation, dissolution or winding up of the Corporation or a Deemed Liquidation Event, the Conversion Rights shall terminate at the close of business on the last full day preceding the date fixed for the payment of any such amounts distributable
on such event to the holders of Preferred Stock. 
 3.2    Fractional Shares. No fractional shares of Common
Stock shall 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. Whether or not fractional shares would be issuable upon such conversion shall 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    Notice of Conversion. In order for a holder of Preferred Stock to voluntarily convert shares of Preferred
Stock into shares of Common Stock, such holder shall (a) provide written notice to the Corporation’s transfer agent at the office of the transfer agent for the Preferred Stock (or at the principal office of the Corporation if the
Corporation serves as its own transfer agent) that such holder elects to convert all or any number of such holder’s shares of Preferred Stock and, if applicable, any event on which such conversion is contingent and (b), if such holder’s
shares are certificated, surrender the certificate or certificates for such shares of Preferred Stock (or, if such registered 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), at the office of the transfer agent for the
Preferred Stock (or at the principal office of the Corporation if the Corporation serves as its own transfer agent). Such notice shall state such holder’s name or the names of the nominees in which such holder wishes the shares of Common Stock
to be issued. If required by the Corporation, any certificates surrendered for conversion shall be endorsed or accompanied by a written instrument or instruments of transfer, in form satisfactory to the Corporation, duly executed by the registered
holder or his, her or its attorney duly authorized in writing. The close of business on the date of receipt by the transfer agent (or by the Corporation if the Corporation serves as its own transfer agent) of such notice and, if applicable,
certificates (or lost certificate affidavit and agreement) shall be the time of conversion (the “Conversion Time”), and the shares of Common Stock issuable upon conversion of the specified shares shall be deemed to be outstanding of
record as of such date. The Corporation shall, as soon as 

  
 8 













 
practicable after the Conversion Time (i) issue and deliver to such holder of Preferred Stock, or to his, her or its nominees, a notice of issuance of uncertificated shares and may, upon
written request, issue and deliver a certificate for the number of full shares of Common Stock issuable upon such conversion in accordance with the provisions hereof and, may, if applicable and upon written request, issue and deliver a certificate
for the number (if any) of the shares of Preferred Stock represented by any surrendered certificate that were not converted into Common Stock, and (ii) pay in cash such amount as provided in Subsection 3.2 in lieu of
any fraction of a share of Common Stock otherwise issuable upon such conversion. 
 3.3.2    Reservation of
Shares. The Corporation shall at all times when the Preferred Stock shall be outstanding, reserve and keep available out of its authorized but unissued capital stock, for the purpose of effecting the conversion of the Preferred Stock, such
number of its duly authorized shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding Preferred Stock; and if at any time the number of authorized but unissued shares of Common Stock shall not be
sufficient to effect the conversion of all then outstanding shares of the Preferred Stock, the Corporation shall take such corporate action as may be necessary to increase its authorized but unissued shares of Common Stock to such number of shares
as shall be sufficient for such purposes, including, without limitation, engaging in best efforts to obtain the requisite stockholder approval of any necessary amendment to this Certificate of Incorporation. Before taking any action which would
cause an adjustment reducing a Conversion Price below the then par value of the shares of Common Stock issuable upon conversion of the applicable series of Preferred Stock, the Corporation will take any corporate action which may, in the opinion of
its counsel, be necessary in order that the Corporation may validly and legally issue fully paid and non-assessable shares of Common Stock at such adjusted Conversion Price. 

3.3.3    Effect of Conversion. All shares of Preferred Stock which shall have been surrendered for conversion as
herein provided shall no longer be deemed to be outstanding and all rights with respect to such shares shall immediately cease and terminate at the 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 Subsection 3.2. Any shares of Preferred Stock so converted 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 accordingly.

 3.3.4    No Further Adjustment. Upon any such conversion, no adjustment to the Conversion Price of any series
of Preferred Stock shall be made on the Common Stock delivered upon conversion. 
 3.3.5    Taxes. The
Corporation shall pay any and all issue and other similar taxes that may be payable in respect of any issuance or delivery of shares of Common Stock upon conversion of shares of Preferred Stock pursuant to this Section 3.
The Corporation shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of shares of Common Stock in a name other than that in which the shares of Preferred Stock so
converted were registered, and no such 

  
 9 













 
issuance or delivery shall be made unless and until the person or entity requesting such issuance has paid to the Corporation the amount of any such tax or has established, to the satisfaction of
the Corporation, that such tax has been paid. 
 3.4    Adjustments to Conversion Price for Diluting
Issues. 
 3.4.1    Special Definitions. For purposes of this Article Fourth, 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 B Original Issue
Date” shall mean the date on which the first share of Series B 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. 

(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 B 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”): 
  

	 	(i)	 shares of Common Stock, Options or Convertible Securities issued as a dividend or distribution on 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 Subsection 3.5, 3.6, 3.7 or 3.8; 



 

	 	(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, including a majority of the Preferred Directors; 


  

	 	(iv)	 shares of Common Stock or Convertible Securities actually issued upon the exercise of Options or shares of
Common Stock 



  
 10 














	 	
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, including a majority of the Preferred Directors; 



 

	 	(vi)	 shares of Common Stock, Options or Convertible Securities issued to suppliers or third-party service providers

	 	(viii)	 shares of Common Stock, Options or Convertible Securities issued in connection with sponsored research,
collaboration, technology license, development, OEM, marketing or other similar agreements or strategic partnerships approved by the Board, including a majority of the Preferred Directors. 



3.4.2    Waiver of Adjustment of Conversion Price. Notwithstanding anything herein to the contrary, any downward
adjustment of the Conversion Price of any series of Preferred Stock as a result of the issuance of Additional Shares of Common Stock (including Additional Shares of Common Stock deemed to be issued pursuant to
Section 3.4.3) may be waived, either prospectively or retroactively and either generally or in a particular instance, by the consent or vote of the holders of a majority of the outstanding shares of such series of
Preferred Stock (each voting as a separate class on an as converted basis). Any such waiver shall bind all holders of such series of Preferred Stock, including future holders. 

  
 11 













 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 B 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
Conversion Price of any series of Preferred Stock 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 Conversion Price of any series of Preferred Stock 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
Conversion Price of such series of Preferred Stock as would have been 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 such Conversion Price to an amount which exceeds the lower of (i) the Conversion Price of any series of Preferred Stock in effect immediately prior to the original adjustment made as a
result of the issuance of such Option or Convertible Security, or (ii) the Conversion Price of any series of Preferred Stock 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 Conversion Price of any series of Preferred Stock 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 Conversion Price of any series of Preferred Stock then in effect, or because such Option or Convertible Security was
issued before the Series B Original Issue Date), are revised after the Series B Original Issue Date as a result of an 

  
 12 













 
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. 

(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 Conversion Price of any series of Preferred Stock pursuant to the terms of Subsection 3.4.4,
the Conversion Price of such series of Preferred Stock shall be readjusted to such Conversion Price as would have been 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 Conversion Price of any series of Preferred Stock 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 Conversion Price of any series of Preferred Stock 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 Conversion Price of
such series of Preferred Stock that such issuance or amendment took place at the time such calculation can first be made. 

3.4.4    Adjustments of Conversion Price upon Issuance of Additional Shares of Common Stock. In the event that
after the Series B Original Issue Date the Company shall 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 Conversion Price for any series of Preferred Stock in effect on the date of and immediately prior to such issue, then and in such event, the Conversion Price of such series of Preferred Stock 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: 

  
 13 













 CP2 = CP1* (A + B) ÷ (A + C). 
 For purposes of the foregoing formula, the following definitions shall
apply: 
 (a)    “CP2” shall mean the Conversion Price
of such series of Preferred Stock in effect immediately after such issue of Additional Shares of Common Stock; 

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

(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 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 CP1 (determined by dividing the aggregate consideration received by the Corporation in respect of such issue by CP1); 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 (or deemed 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; and 


  

	 	(iii)	 in the event Additional Shares of Common Stock are issued (or deemed issued) together with other shares or
securities or other assets of the Corporation for consideration which 



  
 14 














	 	
covers both, be the proportion of such consideration so received, computed at the fair market value thereof, as determined in good faith by the Board. 


(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 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 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). 

  
 15 













 3.5    Adjustments for Stock Splits and Combinations. If the
Corporation shall at any time or from time to time after the Series B Original Issue Date effect a subdivision of the outstanding Common Stock, the Conversion Price of any 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 such series of Preferred Stock shall be increased in proportion to such increase in the aggregate number of shares of Common Stock
outstanding. If the Corporation shall at any time or from time to time after the Series B Original Issue Date combine the outstanding shares of Common Stock, the Conversion Price of any series of Preferred Stock in effect immediately before the
combination shall 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 subsection shall become effective at the close of business on the date the subdivision or combination becomes effective. 

3.6    Adjustment for Certain Dividends and Distributions. In the event the Corporation at any time or from time
to time after the Series B Original Issue Date shall make or issue, or fix 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 of any series of Preferred Stock in effect immediately before such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as
of the close of business on such record date, by multiplying the Conversion Price of such series of Preferred Stock then in effect by a fraction: 

(1)    the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior
to the time of such issuance or the close of business on such record date, and 
 (2)    the denominator of which shall
be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of Common Stock issuable in payment of such dividend or
distribution. 
 Notwithstanding the foregoing: (a) if such record date shall have been fixed and such dividend is not fully paid or if such
distribution is not fully made on the date fixed therefor, the Conversion Price of such series of Preferred Stock shall be recomputed accordingly as of the close of business on such record date and thereafter the Conversion Price of such series of
Preferred Stock shall be adjusted pursuant to this subsection as of the time of actual payment of such dividends or distributions; and (b) no such adjustment shall be made if the holders 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 as they would have received if all outstanding shares of Preferred Stock had been converted into Common Stock on the date of such event. 

  
 16 













 3.7    Adjustments for Other Dividends and Distributions. In the
event the Corporation at any time or from time to time after the Series B Original Issue Date shall make or issue, or fix 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) or in other property, then and in each such event the holders of Preferred Stock shall receive, simultaneously with
the distribution to the holders of Common Stock, a dividend or other distribution of such securities or other property in an amount equal to the amount of such securities or other property as they would have received if all outstanding shares of
Preferred Stock had been converted into Common Stock on the date of such event. 
 3.8    Adjustment for Merger or
Reorganization, etc. Subject to the provisions of Subsection 1.3, if there shall occur any reorganization, recapitalization, reclassification, consolidation or merger involving the Corporation in which the Common Stock (but not the
Preferred Stock) is converted into or exchanged for securities, cash or other property (other than a transaction covered by Subsections 3.4, 3.6 or 3.7), then, following any such reorganization, recapitalization,
reclassification, consolidation or merger, each share of Preferred Stock shall thereafter be convertible in lieu of the Common Stock into which it was convertible prior to such 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 Preferred Stock immediately prior to such reorganization, recapitalization, reclassification, consolidation or merger would have been
entitled to receive pursuant to such transaction; and, in such case, appropriate adjustment (as determined in good faith by the Board) shall be made in the application of the provisions in this Section 3 with respect to the
rights and interests thereafter of the holders of the 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) shall thereafter be applicable, as nearly as reasonably may be, in relation to any securities or other property thereafter deliverable upon the conversion of the Preferred Stock. For the avoidance of doubt, nothing in this Subsection
3.8 shall be construed as preventing the holders of Preferred Stock from seeking any appraisal rights to which they are otherwise entitled under the DGCL in connection with a merger triggering an adjustment hereunder, nor shall this
Subsection 3.8 be deemed conclusive evidence of the fair value of the shares of Preferred Stock in any such appraisal proceeding. 

3.9    Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion
Price pursuant to this Section 3, the Corporation at its expense shall, as promptly as reasonably practicable but in any event not later than ten (10) days thereafter, compute such adjustment or readjustment in
accordance with the terms hereof and furnish to each holder of the applicable series of Preferred Stock a certificate setting forth such adjustment or readjustment (including the kind and amount of securities, cash or other property into which the
applicable series of Preferred Stock is convertible) and showing in detail the facts upon which such adjustment or readjustment is based. The Corporation shall, upon the written request at any time of any holder of Preferred Stock, furnish or cause
to be furnished to 

  
 17 













 
such holder a like certificate setting forth (i) such adjustments and readjustments, (ii) the Conversion Price at the time in effect and (iii) the number of shares of Common Stock
and the amount, if any, of other securities, cash or property which at the time would be received upon the conversion of the applicable series of Preferred Stock. 

3.10    Notice of Record Date. In the event: 

(a)    the Corporation shall take 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; 
 (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, 
 then, and in each such case, the
Corporation will send or cause to be sent to the holders of the Preferred Stock a 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) shall 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. Such notice shall be sent at least ten (10) days prior to the record date or effective date for the event specified in such notice. 

4.    Mandatory Conversion. 

4.1    Trigger Events. Upon either (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, resulting in at least $50,000,000 of gross proceeds to the Corporation (a “Qualified IPO”) or
(b) the date and time, or the occurrence of an event, specified by vote or written consent of the Requisite Majority (the time of such closing or the date and time specified or the time of the event specified in such vote or written consent is
referred to herein as the “Mandatory Conversion Time”), then (i) all outstanding shares of Preferred Stock shall automatically be converted into shares of Common Stock, at the then effective conversion rate as calculated
pursuant to Subsection 3.1.1. and (ii) such shares may not be reissued by the Corporation. 

  
 18 













 4.2    Procedural Requirements. All holders of record of shares
of Preferred Stock shall be sent written notice of the Mandatory Conversion Time and the place designated for mandatory conversion of all such shares of Preferred Stock pursuant to this Section 4. Such notice need not be
sent in advance of the occurrence of the Mandatory Conversion Time. Upon receipt of such notice, each holder of shares of Preferred Stock in certificated form shall surrender his, her or its certificate or certificates for all such shares (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. If so required by the Corporation, any certificates surrendered for conversion shall be endorsed or accompanied by
written instrument or instruments of transfer, in form satisfactory to the Corporation, duly executed by the registered holder or by his, her or its attorney duly authorized in writing. All rights with respect to the Preferred Stock converted
pursuant to Subsection 4.1, including the rights, if any, to receive notices and vote (other than as a holder of Common Stock), will terminate at the Mandatory Conversion Time (notwithstanding the failure of the holder or holders thereof to
surrender any certificates at or prior to such time), except only the rights of the holders thereof, upon surrender of any certificate or certificates of such holders (or lost certificate affidavit and agreement) therefor, to receive the items
provided for in the next sentence of this Subsection 4.2. As soon as practicable after the Mandatory Conversion Time and, if applicable, the surrender of any certificate or certificates (or lost certificate affidavit and agreement) for
Preferred Stock, the Corporation shall (a) issue and deliver to such holder, or to his, her or its nominees, a notice of issuance of uncertificated shares and may, upon written request, issue and deliver a certificate for the number of full
shares of Common Stock issuable upon such conversion in accordance with the provisions hereof and (b) pay cash as provided in Subsection 3.2 in lieu of any fraction of a share of Common Stock otherwise issuable upon
such conversion. 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 accordingly. 
 5.    Redemption. 

5.1    General. Unless prohibited by the provisions of Delaware law governing distributions to stockholders,
shares of Preferred Stock shall be redeemed by the Corporation at a per share price in cash equal to the Original Issue Price per share, plus interest on such amount from the date of issuance at the annual rate of ten percent (10%) (the
“Redemption Price”), in three equal annual installments commencing not more than 60 days after receipt by the Corporation at any time on or after January 5, 2023, from the holders of a majority of the then-outstanding shares of
Preferred Stock (voting together as a single class on an as-converted basis), of written notice requesting redemption of all shares of Preferred Stock (the “Redemption Request”). Upon receipt
of a Redemption Request, the Corporation shall apply all of its assets to any such redemption, and to no other corporate purpose, except to the extent prohibited by the provisions of Delaware law governing distributions to stockholders. The date of
each such installment shall be referred to as a “Redemption Date.” On each Redemption Date, the Corporation shall redeem, on a pro rata basis in accordance with the number of shares 


  
 19 













 
of Preferred Stock owned by each holder, that number of outstanding shares of Preferred Stock determined by dividing (i) the total number of shares of Preferred Stock outstanding immediately
prior to such Redemption Date by (ii) the number of remaining Redemption Dates (including the Redemption Date to which such calculation applies). If on any Redemption Date Delaware law governing distributions to stockholders prevents the
Corporation from redeeming all shares of Preferred Stock to be redeemed on any applicable Redemption Date, the Corporation shall ratably redeem the maximum number of shares that it may redeem consistent with such law and shall redeem the remaining
shares as soon as it may lawfully do so under such law. 
 5.2    Redemption Notice. The Corporation shall send
written notice of the mandatory redemption (the “Redemption Notice”) to each holder of record of Preferred Stock not less than 40 days prior to each Redemption Date. Each Redemption Notice shall state: 

(a)    the number of shares of Preferred Stock held by the holder that the Corporation shall redeem on the Redemption Date
specified in the Redemption Notice; 
 (b)    the Redemption Date and the Redemption Price; 

(c)    the date upon which the holder’s right to convert such shares terminates (as determined in accordance with
Subsection 3.1); and 
 (d)    that the holder is to surrender to the Corporation, in the manner and at the
place designated, his, her or its certificate or certificates, if any, representing the shares of Preferred Stock to be redeemed. 

5.3    Surrender of Certificates; Payment. On or before the applicable Redemption Date, each holder of shares of
Preferred Stock to be redeemed on such Redemption Date, unless such holder has exercised his, her or its right to convert such shares as provided in Section 3, shall surrender any certificate or certificates (if such shares
are then in certificated form), representing such shares (or, if such holder alleges that such a 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, in the manner and at the place designated in the Redemption Notice, and thereupon
the Redemption Price for such shares shall be payable to the order of the person whose name appears on such certificate or certificates as the owner thereof. In the event less than all of the shares of Preferred Stock represented by a certificate
are redeemed, a new certificate, if such shares are in certificated form, representing the unredeemed shares of Preferred Stock shall promptly be issued to such holder. 

5.4    Rights Subsequent to Redemption. If the Redemption Notice shall have been duly given, and if on the
applicable Redemption Date the Redemption Price payable upon redemption of the shares of Preferred Stock to be redeemed on such Redemption Date is paid or tendered for payment or deposited with an independent payment agent so as to be available
therefor in a timely manner, then notwithstanding that the certificates evidencing any of the shares of Preferred Stock, if such shares are in certificated form, so called for redemption 

  
 20 













 
shall not have been surrendered, dividends with respect to such shares of Preferred Stock shall cease to accrue after such Redemption Date and all rights with respect to such shares shall
forthwith after the Redemption Date terminate, except only the right of the holders to receive the Redemption Price without interest upon surrender of their certificate or certificates therefor, if such shares are in certificated form. 

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 shall 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 redemption. 
 7.    Waiver. Any of the rights, powers,
preferences and other terms of the Preferred Stock set forth herein may be waived on behalf of all holders of Preferred Stock by the affirmative written consent or vote of the Requisite Majority. 

8.    Notices. Any notice required or permitted by the provisions of this Article Fourth to be given to a holder of
shares of Preferred Stock shall 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 shall be
deemed sent upon such mailing or electronic transmission.
 FIFTH: Subject to any additional vote required by the Certificate of
Incorporation or 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 of the Corporation. 

SIXTH: Subject to any additional vote required by the Certificate of Incorporation, the number of directors of the Corporation shall be
determined in the manner set forth in the Bylaws of the Corporation. 
 SEVENTH: Elections of directors need not be by written ballot
unless the Bylaws of the Corporation shall so provide. 
 EIGHTH: Meetings of stockholders may be held within or without the State of
Delaware, as the Bylaws of the Corporation may provide. The books of the Corporation may be kept outside the State of Delaware at such place or places as may be designated from time to time by the Board or in the Bylaws of the Corporation. 

NINTH: To the fullest extent permitted by law, a director of the Corporation shall not be personally liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director. If the General Corporation Law or any other law of the State of Delaware is amended after approval by the stockholders of this Article Ninth to authorize corporate action
further eliminating or limiting the personal liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the General Corporation Law as so amended. 

  
 21 













 Any repeal or modification of the foregoing provisions of this Article Ninth by the
stockholders of the Corporation shall not adversely affect any right or protection of a director of the Corporation existing at the time of, or increase the liability of any director of the Corporation with respect to any acts or omissions of such
director occurring prior to, such repeal or modification. 
 TENTH: To the fullest extent permitted by applicable law, the
Corporation is authorized to provide indemnification of (and advancement of expenses to) directors, officers and agents of the Corporation (and any other persons to which General Corporation Law permits the Corporation to provide indemnification)
through Bylaw provisions, agreements with such agents or other persons, vote of stockholders or disinterested directors or otherwise, in excess of the indemnification and advancement otherwise permitted by Section 145 of
the General Corporation Law. 
 Any amendment, repeal or modification of the foregoing provisions of this Article Tenth shall not adversely
affect any right or protection of any director, officer or other agent of the Corporation existing at the time of such amendment, repeal or modification. 

ELEVENTH: The Corporation renounces, to the fullest extent permitted by law, any interest or expectancy of the Corporation in, or in
being offered an opportunity to participate in, any Excluded Opportunity. An “Excluded Opportunity” is any matter, transaction or interest that is presented to, or acquired, created or developed by, or which otherwise comes into the
possession of, (i) any director of the Corporation who is not an employee of the Corporation or any of its subsidiaries, or (ii) any holder of Preferred Stock or any partner, member, director, stockholder, employee or agent of any such
holder, other than someone who is an employee of the Corporation or any of its subsidiaries (collectively, “Covered Persons”), unless such matter, transaction or interest is presented to, or acquired, created or developed by, or
otherwise comes into the possession of, a Covered Person expressly and solely in such Covered Person’s capacity as a director of the Corporation. Any amendment, repeal or modification of the foregoing provisions of this Article Eleventh shall
not adversely affect any right or protection of any director, officer or other agent of the Corporation existing at the time of such amendment, repeal or modification. 

TWELFTH: Unless the Corporation consents in writing to the selection of an alternative forum, the Court of Chancery in the State of
Delaware shall be the sole and exclusive forum for any stockholder (including a beneficial owner) to bring (i) any derivative action or proceeding brought on behalf of the Corporation, (ii) any action asserting a claim of breach of
fiduciary duty owed by any director, officer or other employee of the Corporation to the Corporation or the Corporation’s stockholders, (iii) any action asserting a claim against the Corporation, its directors, officers or employees
arising pursuant to any provision of the Delaware General Corporation Law or the Corporation’s certificate of incorporation or bylaws or (iv) any action asserting a claim against the Corporation, its directors, officers or employees
governed by the internal affairs doctrine, except for, as to each of (i) through (iv) above, any claim as to which the Court of Chancery determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery
(and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten days following such 

  
 22 













 
determination), which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery, or for which the Court of Chancery does not have subject matter jurisdiction.
If any provision or provisions of this Article Twelfth shall be held to be invalid, illegal or unenforceable as applied to any person or entity or circumstance for any reason whatsoever, then, to the fullest extent permitted by law, the validity,
legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Article Twelfth (including, without limitation, each portion of any sentence of this Article Twelfth containing any such provision held
to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) and the application of such provision to other persons or entities and circumstances shall not in any way be affected or impaired thereby.
