 COMMON STOCK PURCHASE WARRANT 
  

			
	 Warrant No.             
	  	Number of Shares: 209,790

  
 ATRICURE, INC.

  
 Effective as of March 8, 2005 
  
 Void after March 8, 2012 
  
 1. Issuance. This Common Stock Purchase Warrant (the
“Warrant”) is issued to LIGHTHOUSE CAPITAL PARTNERS V, L.P. by ATRICURE, INC., a Delaware corporation (hereinafter with its successors called the “Company”). 
  
 2. Purchase Price; Number of Shares. The registered holder of this
Warrant (the “Holder”), commencing on the date hereof, is entitled upon surrender of this Warrant with the subscription form annexed hereto duly executed, at the principal office of the Company, to purchase from the Company at a
price per share of $2.97 (the “Purchase Price”), 209,790 fully paid and nonassessable shares of Common Stock, $0.0001 par value, of the Company (the “Common Stock”). 
  
 Until such time as this Warrant is exercised in full or expires, the Purchase Price and the
securities issuable upon exercise of this Warrant are subject to adjustment as hereinafter provided. The person or persons in whose name or names any certificate representing shares of Common Stock is issued hereunder shall be deemed to have become
the holder of record of the shares represented thereby as at the close of business on the date this Warrant is exercised with respect to such shares, whether or not the transfer books of the Company shall be closed. 
  
 3. Payment of Purchase Price. The Purchase Price may be paid (a) in
cash or by check, (b) by the surrender by the Holder to the Company of any promissory notes or other obligations issued by the Company, with all such notes and obligations so surrendered being credited against the Purchase Price in an amount equal
to the principal amount thereof plus accrued interest to the date of surrender, or (c) by any combination of the foregoing. 
  
 4. Net Issue Election. The Holder may elect to receive, without the payment by the Holder of any additional consideration, shares of Common
Stock equal to the value of this 

 Warrant or any portion hereof by the surrender of this Warrant or such portion to the Company, with the net issue
election notice annexed hereto duly executed, at the principal office of the Company. Thereupon, the Company shall issue to the Holder such number of fully paid and nonassessable shares of Common Stock as is computed using the following formula:

  

					
	 X=  
	 	Y(A-B)	 	 
	 	    A	 	 

  

					
	 where:
	 	 X =
	  	the number of shares of Common Stock to be issued to the Holder pursuant to this Section 4.
			
	 	 	 Y =
	  	the number of shares of Common Stock covered by this Warrant in respect of which the net issue election is made pursuant to this Section 4.
			
	 	 	 A =
	  	the Fair Market Value (defined below) of one share of Common Stock as determined at the time the net issue election is made pursuant to this Section 4.
			
	 	 	 B =
	  	the Purchase Price in effect under this Warrant at the time the net issue election is made pursuant to this Section 4.

  
 “Fair Market Value” of a
share of Common Stock as of the date that the net issue election is made (the “Determination Date”) shall mean: 
  
 (i) If the net issue election is made in connection with and contingent upon the closing of the sale of the Company’s Common Stock to the
public in a public offering pursuant to a Registration Statement under the 1933 Act (a “Public Offering”), and if the Company’s Registration Statement relating to such Public Offering (‘“Registration Statement”) has
been declared effective by the Securities and Exchange Commission, then the initial “Price to Public” specified in the final prospectus with respect to such offering. 
  
 (ii) If the net issue election is not made in connection with and contingent upon a Public Offering, then as follows:

  
 (a) If traded on a securities exchange or the Nasdaq
National Market, the fair market value of the Common Stock shall be deemed to be the average of the closing or last reported sale prices of the Common Stock on such exchange or market over the five day period ending five trading days prior to the
Determination Date; 
  
 (b) If otherwise traded in an
over-the-counter market, the fair market value of the Common Stock shall be deemed to be the average of the closing ask prices of the Common Stock over the five day period ending five trading days prior to the Determination Date; and 
  
 (c) If there is no public market for the Common Stock, then fair
market value shall be determined in good faith by the Company’s Board of Directors. 
  

 - 2 - 

 5. Partial Exercise. This Warrant may be exercised in part, and the Holder shall be entitled to
receive a new warrant, which shall be dated as of the date of this Warrant, covering the number of shares in respect of which this Warrant shall not have been exercised. 
  
 6. Fractional Shares. In no event shall any fractional share of Common Stock be issued upon any exercise of this
Warrant. If, upon exercise of this Warrant in its entirety, the Holder would, except as provided in this Section 6, be entitled to receive a fractional share of Common Stock, then the Company shall issue the next higher number of full shares of
Common Stock, issuing a full share with respect to such fractional share. 
  
 7. Expiration Date; Automatic Exercise. This Warrant shall expire upon the earlier of (i) the close of business on March 8, 2012, or (ii) the close of business on the date that is one year after the date of the
consummation of an initial public offering by the Company of its Common Stock to the public generally pursuant to a registration statement in an underwritten offering, and shall be void thereafter. Notwithstanding the foregoing, this Warrant shall
automatically be deemed to be exercised in full pursuant to the provisions of Section 4 hereof, without any further action on behalf of the Holder, immediately prior to the time this Warrant would otherwise expire pursuant to the preceding sentence
if the Fair Market Value of one share of the Common Stock is greater than the Purchase Price. 
  
 8. Reserved Shares; Valid Issuance. The Company covenants that it will at all times from and after the date hereof reserve and keep available such
number of its authorized shares of Common Stock, free from all preemptive or similar rights therein, as will be sufficient to permit the exercise of this Warrant in full. The Company further covenants that such shares as may be issued pursuant to
such exercise will, upon issuance, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issuance thereof. 
  
 9. Stock Splits and Dividends. If after the date hereof the Company shall subdivide the Common Stock, by split-up or
otherwise, or combine the Common Stock, or issue additional shares of Common Stock in payment of a stock dividend on the Common Stock, the number of shares of Common Stock issuable on the exercise of this Warrant shall forthwith be proportionately
increased in the case of a subdivision or stock dividend, or proportionately decreased in the case of a combination, and the Purchase Price shall forthwith be proportionately decreased in the case of a subdivision or stock dividend, or
proportionately increased in the case of a combination. 
  
 10. Additional Rights. The other rights applicable to the Common Stock of the Company are set forth in the Amended and Restated Certificate of Incorporation, as amended from time to time (the “Articles”), a true and
complete copy in its current form which is attached hereto as Exhibit A. Such rights shall not be restated, amended or modified in any manner which affects the Holder differently than the holders of Common Stock without such Holder’s prior
written consent. The Company shall promptly provide the Holder hereof with any restatement, amendment or modification to the Articles promptly after the same has been made. 
  
 11. Mergers and Reclassifications. If after the date hereof the Company shall enter into any Reorganization (as
hereinafter defined), then, as a condition of such 
  

 - 3 - 

 Reorganization, lawful provisions shall be trade, and duly executed documents evidencing the same from the Company or its
successor shall be delivered to the Holder, so that the Holder shall thereafter have the right to purchase, at a total price not to exceed that payable upon the exercise of this Warrant in full, the kind and amount of shares of stock and other
securities and property receivable upon such Reorganization by a holder of the number of shares of Common Stock which might have been purchased by the Holder immediately prior to such Reorganization, and in any such case appropriate provisions shall
be made with respect to the rights and interest of the Holder to the end that the provisions hereof (including without limitation, provisions for the adjustment of the Purchase Price and the number of shares issuable hereunder and the provisions
relating to the net issue election) shall thereafter be applicable in relation to any shares of stock or other securities and property thereafter deliverable upon exercise hereof. For the purposes of this Section 11, the term
“Reorganization” shall include without limitation any reclassification, capital reorganization or change of the Common Stock (other than as a result of a subdivision, combination or stock dividend provided for in Section 9 hereof), or any
consolidation of the Company with, or merger of the Company into, another corporation or other business organization (other than a merger in which the Company is the surviving corporation and which does not result in any reclassification or change
of the outstanding Common Stock), or any sale or conveyance to another corporation or other business organization of all or substantially all of the assets of the Company. 
  
 12. Certificate of Adjustment. Whenever the Purchase Price is adjusted, as herein provided, the Company shall
promptly deliver to the Holder a certificate of the Company’s chief financial officer setting forth the Purchase Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. 
  
 13. Notices of Record Date, Etc. In the event of: 
  
 (a) any taking by the Company of a record of the holders of any
class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, or any right to subscribe for, purchase, sell or otherwise acquire or dispose of any shares of stock of any class
or any other securities or property, or to receive any other right; 
  
 (b) any reclassification of the capital stock of the Company, capital reorganization of the Company, consolidation or merger involving the Company, or sale or conveyance of all or substantially all of its assets; or 
  
 (c) any voluntary or involuntary dissolution, liquidation or
winding-up of the Company; then in each such event the Company will provide or cause to be provided to the Holder a written notice thereof. Such notice shall be provided at least twenty (20) business days prior to the date specified in such notice
on which any such action is to be taken. 
  
 14.

by the Holder hereof, and shall issue to such Holder a new warrant covering the number of shares in respect of which this Warrant shall not have been transferred. Any transferee shall be subject to the same restrictions on transfer with respect to
this Warrant as the Holder. 
  
 (c) In case this Warrant
shall be mutilated, lost, stolen or destroyed, the Company shall issue a new warrant of like tenor and denomination and deliver the same (i) in exchange and substitution for and upon surrender and cancellation of any mutilated Warrant, or (ii) in
lieu of any Warrant lost, stolen or destroyed, upon receipt of an affidavit of the Holder or other evidence reasonably satisfactory to the Company of the loss, theft or destruction of such Warrant. 
  
 (d) If required by the Company, in connection with each exercise and
issuance of shares of Common Stock purchasable hereunder or in the connection with the transfer by the Holder to any transferee of this Warrant or any of the shares of Common Stock purchasable hereunder, the Holder or such transferee, as the case
may be, will give (i) with respect to any exercise and issuance of shares of Common Stock, assurances in writing that the representations and covenants set forth in Section 17 above remain true and a-e confirmed as of the date of such
exercise, and (ii) with respect to any transfer of this Warrant or any of the shares of Common Stock purchasable hereunder, assurances in writing that the representations and covenants set forth in Section 17 above are true with respect to
such transferee and are confirmed and acknowledged by such transferee. 
  
 19. No Impairment. The Company will not, by amendment of its Articles or through any reclassification, capital reorganization, consolidation, merger, sale or conveyance of assets, dissolution, liquidation, issue or sale of securities
or any other voluntary action, avoid or seek to avoid the observance of performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be
necessary or appropriate in order to protect the rights of the Holder.

Warrant on the date of grant is $100.

 EXHIBIT A 
  

IV. 
  
 The total number of shares of all classes of stock which the Corporation has authority to issue is 63,720,615 shares, consisting of (i) 40,000,000 shares
of Common Stock, par value $.0001 per share (the “Common Stock”), and (ii) 23,720,615 shares of Preferred Stock, par value $.0001 per share (the “Preferred Stock”), of which 8,293,679 shares are designated as Series A Convertible
Preferred Stock (the “Series A Preferred Stock”) and 15,426,936 shares are designated as Series B Convertible Preferred Stock (the “Series B Preferred Stock”). 
  
 Notwithstanding the provisions of Section 242(b)(2) of the Delaware General Corporation Law, the number of authorized shares
of Common Stock may be increased or decreased (but not below the sum of the number of shares of Common Stock then outstanding and the number of shares of Common Stock to be reserved pursuant to Subsection 2(1) below) by the affirmative vote of the
holders of a majority of the stock of the Corporation (voting together on an as-if converted basis). 
  
 The powers, preferences and rights, and the qualifications, limitations or restrictions thereof, in respect of each class or series of stock of the
Corporation shall be as follows: 
  
 Section 1.
Liquidation Rights. 
  
 (a) Liquidation Payments.

  
 (i) In the event of any liquidation, dissolution or winding
up of the affairs of the Corporation, whether voluntary or involuntary (a “Liquidation Event”), before any distribution or payment shall be made to the holders of any other stock of the Corporation, (a) the holders of Series
A Preferred Stock shall be entitled to be paid out of the assets of the Corporation available for distribution to holders of the Corporation’s capital stock an amount equal to $0.63 per share of Series A Preferred Stock (which amount shall be
subject to equitable adjustment whenever there shall occur a stock dividend, stock split, combination of shares, reclassification or other similar event with respect to the Series A Preferred Stock; such price per share, the “Original Series A
Per Share Price”), plus all dividends accrued or declared thereon but unpaid (if any), to and including the date full payment shall be tendered to the holders of the Series A Preferred Stock with respect to such liquidation, dissolution or
winding up, and (b) the holders of Series B Preferred Stock shall be entitled to be paid out of the assets of the Corporation available for distribution to holders of the Corporation’s capital stock an amount equal to $1.43 per share of Series
B Preferred Stock (which amount shall be subject to equitable adjustment whenever there shall occur a stock dividend, stock split, combination of shares, reclassification or other similar event with respect to the Series B Preferred Stock; such
price per share, the “Original Series B Per Share Price”) plus all dividends accrued or declared thereon but unpaid (if any), to and including the date full payment shall be tendered to the holders of the Series B Preferred Stock with
respect to such liquidation, dissolution or winding up. 
  
 If the
assets of the Corporation shall be insufficient to permit the payment in full to the holders of the Series A Preferred Stock and Series B Preferred Stock of all amounts 
  

 3 

 distributable to them under this Subsection l(a)(i), then the entire assets of the Corporation available for such
distribution shall be distributed ratably among the holders of the Series A Preferred Stock and Series B Preferred Stock in proportion to the full preferential amount each such holder is otherwise entitled to receive under this Subsection l(a)(i).

  
 No payment shall be made with respect to the Common Stock
unless and until full payment has been made to the holders of the Preferred Stock of the amounts that they are entitled to receive under this Subsection l(a)(i). 
  
 (ii) After the payments described in Subsection l(a)(i) shall have been made in full to the holders of the Preferred Stock,
or funds necessary for such payments shall have been set aside by the Corporation in trust for the account of holders of Preferred Stock, the remaining assets available for distribution shall be distributed among the holders of the Common Stock,
Series A Preferred Stock and Series B Preferred Stock ratably in proportion to the number of shares of Common Stock then held by them or issuable to them upon conversion of the Series A Preferred Stock or Series B Preferred Stock then held by them.
Such ratable distribution of the remaining assets shall continue until such time as (x) the holders of the Series A Preferred Stock have received aggregate distributions under Subsections l(a)(i) and l(a)(ii) equal to $1.89 per share (in the case of
the cessation of participation of the holders of Series A Preferred Stock) and (y) the holders of the Series B Preferred Stock have received aggregate distributions under Subsections l(a)(i) and l(a)(ii) equal to $4.29 per share (in the case of the
cessation of participation of the holders of Series B Preferred Stock). After such time as the holders of the Series A Preferred Stock and the Series B Preferred Stock have received distributions totaling $1.89 per share and $4.29 per share,
respectively, all remaining assets shall be distributed ratably exclusively to the holders of the Common Stock (and not to any holders of Preferred Stock). 
  
 (iii) Upon conversion of shares of Preferred Stock into shares of Common Stock pursuant to Section 2 below, the holders of such Common Stock shall not be
entitled to any preferential payment or distribution in case of any liquidation, dissolution or winding up, but shall share ratably in any distribution of the assets of the Corporation to all the holders of Common Stock. 
  
 (iv) The amounts payable with respect to shares of Preferred Stock under this
Subsection l(a) are sometimes hereinafter referred to as “Liquidation Payments.” 
  
 (v) Notwithstanding the above, for purposes of determining the amount each holder of shares of Preferred Stock is entitled to receive with respect to a Liquidation Event, each such holder of shares of a series of
Preferred Stock shall be deemed to have converted (regardless of whether such holder actually converted) such holder’s shares of such series into shares of Common Stock immediately prior to the Liquidation Event if, as a result of an actual
conversion, such holder would receive, in the aggregate, an amount greater than the amount that would be distributed to such holder if such holder did not convert such series of Preferred Stock into shares of Common Stock. If any such holder shall
be deemed to have converted shares of Preferred Stock into Common Stock pursuant to this paragraph, then such holder shall not be entitled to receive any distribution that would otherwise be made to holders of Preferred Stock that have not converted
(or have not been deemed to have converted) into shares of Common Stock. 
  

 4 

 (b) Distributions Other than Cash. Whenever the distributions provided for in this Section 1 shall
be payable in property other than cash, the value of such distributions shall be the fair market value of such property as determined in good faith by the Board of Directors of the Corporation. The Corporation shall give prompt written notice of
such valuation to each holder of Preferred Stock. Any securities shall be valued as follows: 
  
 (i) If traded on a securities exchange or through the NASDAQ National Market, the value shall be deemed to be the average of the closing prices of the securities on such quotation system over the thirty (30) day
period ending three (3) days prior to the distribution; 
  
 (ii)
If actively traded over-the-counter, the value shall be deemed to be the average of the closing bid prices over the thirty (30) day period ending three (3) days prior to the distribution; 
  
 (iii) If there is no active public market, the value shall be the fair market value thereof, as determined by the Board of
Directors; and 
  
 (iv) The method of valuation of securities
subject to investment letter or other restrictions on free marketability (other than restrictions arising solely by virtue of a stockholder’s status as an affiliate or former affiliate) shall be made with an appropriate discount from the market
value determined as above to reflect the approximate fair market value thereof, as determined by the Board of Directors. 
  
 (c) Merger as Liquidation, etc. The merger or consolidation of the Corporation into or with another corporation (except one in which the holders of
capital stock of the Corporation immediately prior to such merger or consolidation continue to hold at least fifty percent (50%) in voting power of the capital stock of the surviving corporation, in which case the provisions of Subsection 2(h) shall
apply), the closing of any transaction, or series of transactions, in which more than fifty percent (50%) of the voting power of the Corporation is sold to another corporation or entity or the sale of all, or substantially all, of the assets of the
Corporation, shall be deemed to be a liquidation, dissolution or winding up of the affairs of the Corporation for purposes of this Section 1, unless the holders of (i) at least sixty percent (60%) of the then issued and outstanding shares of Series
A Preferred Stock; and (ii) at least a majority in interest of the then issued and outstanding shares of Series B Preferred Stock, each such series voting as separate classes, elect to the contrary, such election to be made by giving written notice
thereof to the Corporation at least five (5) days before the effective date of such event. If such notice is given with respect to the Series A Preferred Stock and Series B Preferred Stock, the provisions of Subsection 2(h) shall apply to such
Preferred Stock. Unless such election is made by the requisite holders of a series of Preferred Stock, any amounts received by the holders of such series of Preferred Stock as a result of such merger or consolidation shall be deemed to be applied
toward, and all consideration received by the Corporation in such asset sale together with all other available assets of the Corporation shall be distributed toward, the Liquidation Payments in the order of preference set forth in Subsection l(a).

  
 (d) Notice. Notice of any proposed liquidation ,
dissolution or winding up of the affairs of the Corporation (including any merger, consolidation, sale of capital stock or sale of 

  

 5 

 
assets which may be deemed to be a liquidation, dissolution or winding up of the affairs of the Corporation under Subsection l(c)), stating a payment date,
the amount of the Liquidation Payments and the place where said Liquidation Payments shall be payable, shall be given to the holders of record of Preferred Stock not less than thirty (30) days prior to the payment date stated therein. Any holder of
outstanding shares of Preferred Stock may waive notice required by this Subsection by a written document specifically indicating such waiver. 
  
 Section 2. Conversion. The holders of Preferred Stock shall have conversion rights as follows (the “Conversion Rights”):

  
 (a) Right to Convert; Conversion Price. Each share of
Preferred Stock shall be convertible, without the payment of any additional consideration by the holder thereof and at the option of the holder thereof, at any time after the date of issuance of such share, at the principal executive office of the
Corporation or any transfer agent for the Preferred Stock, into such number of fully paid and nonassessable shares of Common Stock as is determined by dividing the Issuance Price by the Conversion Price for such series, determined as hereinafter
provided, in effect at the time of conversion. The “Issuance Price” shall be $0.63 per share for the Series A Preferred Stock and $1.43 per share for the Series B Preferred Stock. The conversion price at which shares of Common Stock shall
be deliverable upon conversion of Preferred Stock without the payment of any additional consideration by the holder thereof (the “Conversion Price”) shall initially be $0.63 per share of Common Stock for the Series A Preferred Stock and
$1.43 per share of Common Stock for the Series B Preferred Stock subject, in each case, to adjustment in order to adjust the number of shares of Common Stock into which the Preferred Stock is convertible, as hereinafter provided. All references to
the Conversion Price herein shall mean the Conversion Price as so adjusted. 
  
 (b) Automatic Conversion. 
  
 (i) Each share of Preferred Stock shall automatically be converted into shares of Common Stock, based on the Conversion Price then in effect for such series of Preferred Stock, upon the closing of a firm commitment underwritten public
offering (a “Qualified Public Offering”) pursuant to an effective registration statement under the Securities Act of 1933, as amended (the “Act”), covering the offer and sale of Common Stock for the account of the Corporation to
the public at an offering price per share (prior to underwriter commissions and discounts) of not less than $4.29 (as adjusted to reflect any stock dividends, distributions, combinations, reclassifications or other like transactions effected by the
Corporation in respect of its Common Stock) and with proceeds (after deduction of underwriters’ commissions and expenses) to the Corporation of not less than $30,000,000.00 (in the event of which Qualified Public Offering, the person(s)
entitled to receive the Common Stock issuable upon such conversion of the Preferred Stock shall not be deemed to have converted the Preferred Stock until the closing of such Qualified Public Offering). Notwithstanding the foregoing, a registration
relating solely to a transaction under Rule 145 under the Act (or any successor thereto) or to an employee benefit plan of the Corporation shall not be deemed to be a Qualified Public Offering causing the automatic conversion of the Preferred Stock
into shares of Common Stock. 
  

 6 

 (ii) With respect to the Series A Preferred Stock, each share of Series A Preferred Stock shall
automatically be converted into shares of Common Stock, based on the Conversion Price then in effect for the Series A Preferred Stock, upon the written election of the holders of not less than sixty percent (60%) of the then issued and outstanding
shares of Series A Preferred Stock, voting as a separate class. With respect to the Series B Preferred Stock, each share of Series B Preferred Stock shall automatically be converted into shares of Common Stock, based on the Conversion Price then in
effect for the Series B Preferred Stock, upon the written election of the holders of not less than fifty percent (50%) of the then issued and outstanding shares of Series B Preferred Stock, voting as a separate class. 
  
 (c) Mechanics of Automatic Conversions. Upon the occurrence of either
of the events specified in Subsection 2(b), the outstanding shares of the applicable series of Preferred Stock shall be converted automatically without any further action by the holders of shares of such series and whether or not the certificates
representing such shares are surrendered to the Corporation or its transfer agent; provided, that all holders of shares of Preferred Stock being converted shall be given written notice of the occurrence of the event specified in Subsection
2(b) triggering such conversion, including the date such event occurred (the “Automatic Conversion Date”), and the Corporation shall not be obligated to issue certificates evidencing the shares of Common Stock issuable upon such conversion
unless the certificates evidencing such shares of Preferred Stock being converted are either delivered to the Corporation or its transfer agent, or the holder notifies the Corporation or any transfer agent that such certificates have been lost,
stolen, or destroyed and executes an agreement reasonably satisfactory to the Corporation to indemnify the Corporation from any loss incurred by it in connection therewith. On the Automatic Conversion Date, all rights with respect to the series of
Preferred Stock so converted, shall terminate, except any of the rights of the holder thereof, upon surrender of the holder’s certificate or certificates therefor, to receive certificates for the number of shares of Common Stock into which such
series of Preferred Stock has been converted, together with cash in an amount equal to all dividends declared but unpaid on, and any and all other amounts owing with respect to, the shares of Preferred Stock converted to and including the time of
conversion. Upon the automatic conversion of any Preferred Stock, the holders of such series of Preferred Stock shall surrender the certificates representing such shares at the office of the Corporation or of its transfer agent. If so required by
the Corporation, 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 the holder’s
attorney duly authorized in writing. Upon surrender of such certificates there shall be issued and delivered to such holder, promptly at such office and in the holder’s name as shown on such surrendered certificate or certificates, a
certificate or certificates for the number of shares of Common Stock into which the shares of Preferred Stock so surrendered were convertible on the date on which such automatic conversion occurred, together with cash in an amount equal to all
dividends declared but unpaid on, and any and all other amounts owing with respect to, the shares of Preferred Stock converted to and including the time of conversion. No fractional share of Common Stock shall be issued upon automatic conversion of
any Preferred Stock. In lieu of any fractional share to which the holder would otherwise be entitled, the Corporation shall pay cash equal to such fraction multiplied by the fair market value of one share of Common Stock on the Automatic Conversion
Date, as determined in good faith by the Corporation’s Board of Directors. 
  

 7 

 (d) Mechanics of Optional Conversions. Before any holder of Preferred Stock shall be entitled to
voluntarily convert the same into shares of Common Stock pursuant to Subsection 2(a), the holder shall surrender the certificate or certificates therefor at the office of the Corporation or of any transfer agent for the Preferred Stock, and shall
give written notice to the Corporation at such office that the holder elects to convert the same and shall state therein the holder’s name or the name or names of the holder’s nominees in which the holder wishes the certificate or
certificates for shares of Common Stock to be issued. On the date of conversion, all rights with respect to the Preferred Stock so converted, shall terminate, except any of the rights of the holders thereof, upon surrender of their certificate or
certificates therefor, to receive certificates for the number of shares of Common Stock into which such Preferred Stock has been converted and cash in an amount equal to all dividends declared but unpaid on, and any and all other amounts owing with
respect to, the shares of Preferred Stock being converted to and including the time of conversion. If so required by the Corporation, 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 the holder’s attorney duly authorized in writing. No fractional share of Common Stock shall be issued upon optional conversion of any Preferred
Stock. In lieu of any fractional share to which the holder would otherwise be entitled, the Corporation shall pay cash equal to such fraction multiplied by the then current fair market value of one share of Common Stock, as determined in good faith
by the Corporation’s Board of Directors. The Corporation shall, as soon as practicable (but in no event later than five (5) business days) after surrender of the certificate or certificates for conversion, issue and deliver at such office to
such holder of Preferred Stock, or to the holder’s nominee or nominees, a certificate or certificates for the number of shares of Common Stock to which the holder shall be entitled as aforesaid, together with cash in lieu of any fraction of a
share and cash in an amount equal to all dividends declared but unpaid thereon and any and all other amounts owing with respect thereto at such time. Such conversion shall be deemed to have been made immediately prior to the close of business on the
date of such surrender of the shares of Preferred Stock to be converted, and the person or persons entitled to receive the shares of Common Stock issuable upon conversion shall be treated for all purposes as the record holder or holders of such
shares of Common Stock on such date. 
  
 (i) If the conversion is
in connection with an underwritten offering of securities pursuant to the Act the conversion may, at the option of any holder tendering shares of Preferred Stock for conversion, be conditioned upon the closing with the underwriters of the sale of
securities pursuant to such offering, in which event the person(s) entitled to receive the Common Stock upon conversion of such Preferred Stock shall not be deemed to have converted such Preferred Stock until immediately prior to the closing of such
sale of securities. 
  
 (ii) If the conversion is in connection
with a liquidation described in Subsection l(c) above, the conversion may, at the option of any holder tendering shares of Preferred Stock for conversion, be conditioned upon the consummation of the liquidation, in which event the person(s) entitled
to receive the Common Stock upon conversion of such Preferred Stock shall not be deemed to have converted such Preferred Stock until immediately prior to the consummation of the liquidation. 
  
 (e) Adjustments to Conversion Price for Diluting Issues.

 (i) Special Definitions. For purposes of this Subsection 2(e), the following definitions shall
apply: 
  
 (1) “Option” shall mean rights,

 (2) “Original Issue Date” shall mean the first date on which a share of Series B Preferred Stock was issued. 
  
 (3) “Convertible Securities” shall mean any evidences of
indebtedness, shares of capital stock (other than Common Stock) or other securities directly or indirectly convertible into or exchangeable for Common Stock. 
  
 (4) “Additional Shares of Common Stock” shall mean all shares of Common Stock issued (or, pursuant to Subsection 2(e)(iii), deemed to be

such majority includes all directors elected exclusively by the holders of Preferred Stock in accordance with Section 5(b)(i) and 5(b)(ii) (the “Preferred Directors”)); notwithstanding the foregoing, any shares of Common Stock issued or
deemed to be issued primarily for equity financing purposes shall be Additional Shares of Common Stock;

Subsection 2(e)(vi). 
  
 (ii) No Adjustment of Conversion
Price. Except as set forth in Subsection 2(e)(vi), no adjustment in the number of shares of Common Stock into which each share of Preferred Stock is convertible shall be made, by adjustment of the Conversion Price for such series of Preferred
Stock, in respect of the issuance of Additional Shares of Common Stock unless the consideration per share for an Additional Share of Common Stock (determined pursuant to Subsection 2(e)(v)) issued or deemed to be issued by the Corporation is less
than the Conversion Price for such series of Preferred Stock in effect on the date of, and immediately prior to, the issue of such Additional Share of Common Stock. 
  
 (iii) Deemed Issue of Additional Shares of Common Stock. 
  
 (1) Options and Convertible Securities. In the event the Corporation
at any time or from time to time after the Original Issue Date shall issue any Options or Convertible 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 (as set forth in the instrument relating thereto without regard to any provisions contained therein for a subsequent adjustment of such number) of Common Stock 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; provided, that in any such case in which Additional Shares of Common Stock are deemed to be issued: 
  
 (A) no further adjustment in the Conversion Price shall be made upon the
subsequent issue of Convertible Securities or shares of Common Stock upon the exercise of such Options or conversion or exchange of such Convertible Securities; 
  

(B) if such Options or Convertible Securities by their terms provide, with the passage of time or otherwise, for any increase in the consideration
payable to the Corporation, or decrease in the number of shares of Common Stock issuable, upon the exercise, conversion or exchange thereof, the Conversion Price as adjusted upon the original issue thereof (or upon the occurrence of a record date
with respect thereto), and any subsequent adjustments based thereon, shall, upon any such increase or decrease becoming effective, be readjusted to reflect such increase or decrease insofar as it affects such Options or the rights of conversion or
exchange under such Convertible Securities; 
  
 (C) if such
Options or Convertible Securities by their terms provide, with the passage of time or otherwise, for any decrease in the consideration payable to the Corporation, or increase in the number of shares of Common Stock issuable, upon the exercise,
conversion or exchange thereof, the Conversion Price as adjusted upon the original issue thereof (or upon the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon, shall, upon any such decrease or increase
becoming effective, be 

  

 10 

 
readjusted to reflect such decrease or increase insofar as it affects such Options or the rights of conversion or exchange under such Convertible Securities;

  
 (D) upon the expiration of any such Options or any rights of
conversion or exchange under such Convertible Securities which shall not have been exercised, the Conversion Price as adjusted upon the original issue thereof (or upon the occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon such expiration, be readjusted as if: 
  
 (I) in the case of Convertible Securities or Options for Common Stock the only Additional Shares of Common Stock issued were the shares of Common Stock, if any, actually issued upon the exercise of such Options or the
conversion or exchange of such Convertible Securities and the consideration received therefor was the consideration actually received by the Corporation for the issue of all such Options, whether or not exercised, plus the consideration actually
received by the Corporation upon such exercise, or for the issue of all such Convertible Securities which were actually converted or exchanged, plus the additional consideration, if any, actually received by the Corporation upon such conversion or
exchange; and 
  
 (II) in the case of Options for Convertible
Securities, only the Convertible Securities, if any, actually issued upon the exercise thereof were issued at the time of issue of such Options, and the consideration received by the Corporation for the Additional Shares of Common Stock deemed to
have been then issued was the consideration actually received by the Corporation for the issue of all such Options, whether or not exercised, plus the consideration deemed to have been received by the Corporation (determined pursuant to Subsection
2(e)(v)) upon the issue of the Convertible Securities with respect to which such Options were actually exercised; 
  
 (E) no readjustment pursuant to this Section 2(e) shall have the effect of increasing the applicable Conversion Price for a series of Preferred Stock;
and 
  
 (F) if such record date shall have been fixed and such
Options or Convertible Securities are not issued on the date fixed therefor, the adjustment previously made in the Conversion Price which became effective on such record date shall be cancelled as of the close of business on such record date, and
thereafter the Conversion Price shall be adjusted pursuant to this Subsection 2(e)(iii) as of the actual date of their issuance. 
  
 (2) Stock Dividends, Stock Distributions and Subdivisions. In the event the Corporation at any time or from time to time after the Original Issue
Date shall declare or pay any dividend or make any other distribution on the Common Stock payable in Common Stock or effect a subdivision of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in
Common Stock), then and in any such event, Additional Shares of Common Stock shall be deemed to have been issued with respect to the Preferred Stock: 
  

 11 

 (A) in the case of any such dividend or distribution, immediately after the close of business on the
record date for the determination of holders of any class of securities entitled to receive such dividend or distribution; or 
  
 (B) in the case of any such subdivision, at the close of business on the date immediately prior to the date upon which such corporate action becomes
effective. 
  
 If such record date shall have been fixed and no
part of such dividend or distribution shall have been paid on the date fixed therefor, the adjustment previously made in the Conversion Price which became effective on such record date shall be cancelled as of the close of business on such record
date, and thereafter the Conversion Price shall be adjusted pursuant to this Subsection 2(e)(iii) as of the time of actual payment of such dividend or distribution. 
  
 (iv) Adjustment of Conversion Price Upon Issuance of Additional Shares of Common Stock. In the event that at any time
or from time to time after the Original Issue Date, the Corporation shall issue Additional Shares of Common Stock (including, without limitation, Additional Shares of Common Stock deemed to be issued pursuant to Subsection 2(e)(iii)(l) but excluding
Additional Shares of Common Stock deemed to be issued pursuant to Subsection 2(e)(iii)(2), which event is dealt with in Subsection 2(e)(vi)(l)), without consideration or for a consideration per share less than the Conversion Price for Series A
Preferred Stock or Series B Preferred Stock in effect on the date of and immediately prior to such issue, then and in such event, the then-existing Conversion Price for such affected series of Preferred Stock shall be reduced, concurrently with such
issue, to a price determined in accordance with the following formula: 
  

							
	 	  	NCP	  	=	  	 P1Q1 + AC

	 	  	  	  	  Q1 + Q2
	where:	  	 	  	 	  	 
	 	  	NCP	  	=	  	New Conversion Price.
				
	 	  	P1	  	=	  	Conversion Price in effect immediately prior to new issue.
				
	 	  	Q1	  	=	  	Number of shares of Common Stock outstanding, or deemed to be outstanding as set forth below, immediately prior to such issue.
				
	 	  	AC	  	=	  	The aggregate consideration received by the Corporation for the shares of Common Stock issued, or deemed to have been issued, in the subject transaction.
				
	 	  	Q2	  	=	  	Number of shares of Common Stock issued, or deemed to have been issued, in the subject transaction.

  

 12 

 provided, that for the purpose of this Subsection 2(e)(iv), all shares of Common Stock issuable upon conversion of
shares of Preferred Stock outstanding immediately prior to such issue shall be deemed to be outstanding, and immediately after any Additional Shares of Common Stock are deemed issued pursuant to Subsection 2(e)(iii), such Additional Shares of Common
Stock shall be deemed to be outstanding. 
  
 (v) Determination
of Consideration. For purposes of this Subsection 2(e), the consideration received by the Corporation for the issue of any Additional Shares of Common Stock shall be computed as follows: 
  
 (1) Cash and Property: Such consideration shall: 
  
 (A) insofar as it consists of cash, be computed at the aggregate amounts of
cash received by the Corporation excluding amounts paid or payable for accrued interest or accrued dividends; 
  
 (B) insofar as it consists of property other than cash, be computed at the fair value thereof at the time of such issue, as determined in good faith by
the Corporation’s Board of Directors; and 
  
 (C) 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
(A) and (B) above, as determined in good faith by the Corporation’s Board of Directors. 
  
 (2) 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 2(e)(iii)(1), relating to
Options and Convertible Securities, shall be determined by dividing (x) 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 (y) 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. 
  
 (vi) Adjustment
for Dividends, Distributions, Subdivisions, Combinations or Consolidations of Common Stock. 
  
 (1) Stock Dividends, Distributions or Subdivisions. In the event the Corporation shall be deemed to issue Additional Shares of Common Stock
pursuant to Subsection 2(e)(iii)(2) in a stock dividend, stock distribution or subdivision, the Conversion 

  

 13 

 Price in effect immediately before such deemed issuance shall, concurrently with the effectiveness of such deemed
issuance, be proportionately decreased. 
  
 (2) Combinations
or Consolidations. In the event the outstanding shares of Common Stock shall be combined or consolidated, by reclassification or otherwise, into a lesser number of shares of Common Stock, the Conversion Price in effect immediately prior to such
combination or consolidation shall, concurrently with the effectiveness of such combination or consolidation, be proportionately increased. 
  
 (f) Adjustments for Certain Dividends and Distributions. In the event that at any time or from time to time after the Original Issue Date the
Corporation 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 assets or in securities of the Corporation other than shares of Common Stock, and
other than as otherwise adjusted in this Section 2, then and in each such event provision shall be made so that the holders of the Preferred Stock shall receive upon conversion thereof in addition to the number of shares of Common Stock receivable
thereupon, the amount of assets or securities of the Corporation that they would have received had their Preferred Stock been converted into Common Stock on the date of such event and had they thereafter, during the period from the date of such
event to and including the conversion date, retained such assets or securities receivable by them as aforesaid during such period, giving application during such period to all adjustments called for herein. 
  
 (g) Adjustment for Reclassification, Exchange, or Substitution. In the
event that at any time or from time to time after the Original Issue Date, the Common Stock issuable upon the conversion of the Preferred Stock shall be changed into the same or a different number of shares of any class or series of stock or other
securities or property, whether by capital reorganization, reclassification, or otherwise (other than a subdivision or combination of shares or stock dividend provided for above, or a merger, consolidation, or sale of assets provided for below),
then and in each such event the holder of Preferred Stock shall have the right thereafter to convert such shares into the kind and amount of shares of stock and other securities and property receivable upon such reorganization, reclassification, or
other change, by the holder of a number of shares of Common Stock equal to the number of shares of Common Stock into which such shares of Preferred Stock might have been converted immediately prior to such reorganization, reclassification, or
change, all subject to further adjustment as provided herein. 
  
  
 (h) Adjustment for Merger, Consolidation or Sale of Assets. In the event that at any time or from time to time after the Original Issue Date, the
Corporation shall merge or consolidate with or into another entity or sell all or substantially all of its assets (other than a consolidation, merger or sale which is treated as a liquidation with respect to the Preferred Stock pursuant to
Subsection 1(c)), each share of Preferred Stock shall thereafter be convertible into the kind and amount of shares of stock or other securities or property to which a holder of the number of shares of Common Stock of the Corporation deliverable upon
conversion of such shares of Preferred Stock would have been entitled to receive upon such consolidation, merger or sale; and, in such case, appropriate adjustment (as determined in good faith by the Corporation’s Board of Directors) shall be
made in the application of the provisions set forth in this Section 2 with respect to the rights and interest thereafter of the holders of such Preferred Stock, to the end 

  

 14 

 
that the provisions set forth in this Section 2 (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 shares of stock or other securities or property thereafter deliverable upon the conversion of such Preferred Stock. 
  
 (i) No Impairment. The Corporation shall not, by amendment of its
Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms
to be observed or performed hereunder by the Corporation but shall at all times in good faith assist in the carrying out of all the provisions of this Section 2 and in the taking of all such action as may be necessary or appropriate in order to
protect the Conversion Rights of the holders of the Preferred Stock against impairment. 
  
 (j) Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price pursuant to this Section 2, the Corporation at its expense shall promptly compute such
adjustment or readjustment in accordance with the terms hereof and mail to each affected holder of Preferred Stock, by first class mail, postage prepaid, a certificate setting forth such adjustment or readjustment and showing in detail the facts
upon which such adjustment or readjustment is based. The certificate shall set 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 property which at the time would be received upon the conversion of each share of Preferred Stock affected. 
  
 (k) Notices of Record Date. In the event that the Corporation shall propose at any time: (i) to declare any dividend or distribution upon its
Common Stock, whether in cash, property, stock or other securities, whether or not a regular cash dividend and whether or not out of earnings or earned surplus; (ii) to offer for subscription pro rata to the holders of any class or series of its
stock any additional shares of stock of any class or series or other rights; (iii) to effect any reclassification or recapitalization of its Common Stock outstanding involving a change in the Common Stock; or (iv) to merge or consolidate with or
into any other corporation, or sell, lease or convey all or substantially all of its assets, or to liquidate, dissolve or wind up; then, in connection with each such event, the Corporation shall send to the holders of Preferred Stock: 
  
 (A) at least twenty (20) days’ prior written notice of
the date on which a record shall be taken for such dividend, distribution or subscription rights (and specifying the date on which the holders of Common Stock shall be entitled thereto) or for determining rights to vote, if any, in respect of the
matters referred to in (i) and (ii) above; and 
  
 (B) in the case of the matters referred to in (iii) and (iv) above, at least twenty (20) days’ prior written notice of the date when the same shall take place (and specifying the date on which the holders of Common Stock shall be
entitled to exchange their Common Stock for securities or other property deliverable upon the occurrence of such event). 
  
 (l) Common Stock Reserved. The Corporation shall at all times reserve and keep available out of its authorized but unissued Common Stock, solely
for the purpose of effecting 
  

 15 

 
the conversion of the shares of Preferred Stock, such number of shares of Common Stock as shall from time to time be sufficient to effect the conversion of
all outstanding shares of the Preferred Stock. 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 Preferred Stock, the Corporation will take
such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purpose. 
  
 (m) Certain Taxes. The Corporation shall pay any issue or transfer
taxes payable in connection with the conversion of Preferred Stock; provided, however, that the Corporation shall not be required to pay any tax which may be payable in respect of any transfer to a name other than that of the holder of
the Preferred Stock. 
  
 (n) Closing of Books. The
Corporation shall at no time close its transfer books against the transfer of any Preferred Stock or of any shares of Common Stock issued or issuable upon the conversion of any shares of Preferred Stock in any manner which interferes with the timely
conversion or transfer of such Preferred Stock or Common Stock. 
  
 (o) Good Faith. If any event occurs as to which in the reasonable opinion of the Board of Directors of the Corporation, in good faith, the other provisions of this Section 2 are not strictly applicable but the lack of any adjustment
in the Conversion Price would not in the reasonable opinion of the Board fairly protect the Conversion Rights of the holders of such Preferred Stock in accordance with the basic intent and principles of such provisions, or if strictly applicable
would not fairly protect the Conversion Rights of the holders of such Preferred Stock in accordance with the basic intent and principles of such provisions, then the Board of Directors of the Corporation shall cause the Corporation forthwith to make
such adjustment, if any, to the Conversion Price, on a basis consistent with the basic intent and principles of this Section 2, as it in good faith considers necessary to preserve, without dilution, the Conversion Rights of all the holders of such
Preferred Stock. 
  
 Section 3. Redemption Event.

  
 (a) Upon request in writing to the Corporation by either (y)
the holders of at least 66 2/3% in interest of the then issued and outstanding shares of Series A Preferred
Stock, making a request as a separate class or (z) the holders of at least a majority in interest of the then issued and outstanding shares of Series B Preferred Stock, making a request as a separate class (the holders of such requesting series of
Preferred Stock, the “Requesting Holders,” and such request, an “Initial Redemption Request”), the Requesting Holders may cause the Corporation, on June 6, 2007 and on each of the first and second anniversaries thereof (each such
date being referred to hereinafter as a “Redemption Date”), to redeem from all holders of such series of Preferred Stock, at the Original Series A Per Share Price or the Original Series B Per Share Price, as applicable, plus (i) any
dividends declared or accrued but unpaid thereon, if any, and (ii) (x) if Series A Preferred Stock, an amount equal to fifteen percent (15%) per annum (by simple interest calculation) of the Original Series A Per Share Price from the date of
May 25, 2001 through and until the applicable Redemption Date or (y) if Series B Preferred Stock, an amount equal to fifteen percent (15%) per annum (by simple interest calculation) of the Original Series B 

  

 16 

 
Per Share Price from the date of June 6, 2002 through and until the applicable Redemption Date (the redemption price for the Series A Preferred Stock or
Series B Preferred Stock, as applicable, the “Redemption Price”), the following respective portions of the number of issued and outstanding shares of Preferred Stock held by all holders of such series of Preferred Stock on the applicable
Redemption Date: 
  

			
	 Redemption Date

	  	Portion of Shares of Preferred
Stock To Be Redeemed

	 June 6, 2007
	  	33 1/3%
	 June 6, 2008
	  	66 2/3%
	 June 6, 2009
	  	100%

  
 (b) If any of the
outstanding shares of a particular series of Preferred Stock are redeemed by the Corporation pursuant to Subsection 3(a) above, then all outstanding shares of such series of Preferred Stock must be redeemed by the Corporation in accordance with
Subsection 3(a). However, if the funds of the Corporation legally available for redemption of Preferred Stock on any Redemption Date are insufficient to redeem the entire number of shares of Preferred Stock required under this Section 3 to be
redeemed on such date, then those funds which are legally available will be used to redeem the maximum possible number of such shares of Preferred Stock ratably on the basis of the number of shares of Preferred Stock which would be redeemed on such
date if the funds of the Corporation legally available therefor had been sufficient to redeem the entire number of shares of Preferred Stock required to be redeemed on such date. At any time thereafter when additional funds of the Corporation become
legally available for the redemption of Preferred Stock, such funds will be used, at the end of the next succeeding fiscal quarter, to redeem the balance of the shares which the Corporation was theretofore obligated to redeem, ratably on the basis
set forth in the preceding sentence. The portion of the Redemption Price due but unpaid on any Redemption Date shall accrue interest at the rate of fifteen percent (15%) per annum until paid, and any payments by the Corporation shall be applied
first to such interest and then to reducing the amount of the unpaid Redemption Price. 
  
 (c) The Corporation shall provide notice of its receipt of an Initial Redemption Request, specifying the time, manner and place of redemption and the Redemption Price (a “Redemption Notice”), by first class
or registered mail, postage prepaid, to each holder of record of Preferred Stock at the address for such holder as last shown on the records of the transfer agent therefor (or the records of the Corporation, if it serves as its own transfer agent),
not less than thirty (30) days prior to the applicable Redemption Date. All holders of record of the series of Preferred Stock that did not make such Initial Redemption Request may nonetheless elect to become, together with the initial Requesting
Holders, the “Requesting Holders” on such Redemption Date if written notice(s) is mailed to the Corporation, by first class or registered mail, postage prepaid, at least ten (10) days prior to applicable Redemption Date, which 

notice(s) includes the requisite percent of the then issued and outstanding shares of such series of Preferred Stock necessary to make an Initial Redemption Request
pursuant to Subsection 3(a) above. 
  
 (d) Upon receipt by the
Corporation of an Initial Redemption Request, the Corporation will become obligated to redeem on the applicable Redemption Date all then 
  

 17 

 
outstanding shares of the applicable series of Preferred Stock in accordance with Subsection 3(a) (other than the shares of such series of Preferred Stock as
are duly converted pursuant to Section 2 hereof prior to the close of business on the fifth (5th) full day preceding
the Redemption Date). Except as provided in Subsection 3(b) above, each Requesting Holder shall surrender to the Corporation on the applicable Redemption Date the certificate(s) representing the shares to be redeemed on such date, in the manner and
at the place designated in the Redemption Notice. Thereupon, the Redemption Price shall be paid to the order of each such Requesting Holder and each certificate surrendered for redemption shall be canceled. In the case less than all Preferred Stock
represented by any certificate is redeemed in any redemption pursuant to this Section 3, a new certificate will be issued representing the unredeemed Preferred Stock without cost to the holder thereof. 
  
 (e) Until a share of Preferred Stock is actually redeemed, each such share
shall be entitled to any dividends declared upon such series of Preferred Stock and, until a share of Preferred Stock is actually redeemed, all rights of the holder of such share as a stockholder of the Corporation by reason of the ownership of such
share (including, without limitation, voting rights and conversion rights) will continue in full force and effect. 
  
 Section 4. Restrictions. 
  
 (a) At any time when at least 1,000,000 shares of Preferred Stock are outstanding, except where the vote of the holders of a greater number of shares of
Series A Preferred Stock and/or Series B Preferred Stock is required by law or by this Certificate of Incorporation, and in addition to any other vote required by law or by this Certificate of Incorporation, without the affirmative vote or written
consent of both: (y) the holders of at least a majority in interest of the then issued and outstanding shares of Series A Preferred Stock; and (z) the holders of at least a majority in interest of the then issued and outstanding shares of Series B
Preferred Stock, voting as separate classes, the Corporation will not: 
  
 (i) amend, alter or change the designation of any preferences, voting or other powers, qualifications, or special or relative rights or privileges of any series of Preferred Stock that adversely affects such Preferred
Stock or the holders thereof; 
  
 (ii) increase
or decrease (other than pursuant to a redemption or conversion contemplated by this Certificate of Incorporation) the authorized number of shares of any series of Preferred Stock; 
  
 (iii) create, authorize or issue any class or series of stock having any preference or priority over or
being on a parity with any such preference or priority of any series of Preferred Stock or any security convertible into or exchangeable or exercisable for any such class a series of stock; 
  
 (iv) effect any license of the Corporation’s
technology, other than in the ordinary course of business, in such a manner as to have the same economic effect as the sale of all or substantially all of the properties or assets of the Corporation; 
  
 (v) effect any liquidation, dissolution or winding up of the
Corporation; 
  

 18 

 (vi) effect any sale, lease, assignment, transfer or other conveyance (other than the
grant of a mortgage or security interest in connection with indebtedness for borrowed money) of all or substantially all of the properties or assets of the Corporation; 
  
 (vii) effect any amendment, alteration or change of this Certificate of Incorporation that adversely affects
any of the rights of any series of Preferred Stock set forth in this Certificate of Incorporation or by law; 
  
 (viii) effect any redemption or repurchase with respect to any shares of Common Stock (except for acquisitions of Common Stock by the
Corporation pursuant to agreements approved by the Corporation’s Board of Directors that permit the Corporation to repurchase such shares at no greater amount than their original purchase price upon termination of services to the Corporation or
in exercise of the Corporation’s right of first refusal upon a proposed transfer); 
  
 (ix) redeem, purchase or otherwise acquire for value (or pay into or set aside for a sinking fund for such purpose) any shares of
Preferred Stock otherwise than by redemption in accordance with Section 3 hereof or by conversion in accordance with Section 2 hereof; 
  
 (x) reissue any share of Preferred Stock acquired by the Corporation by reason of redemption, purchase, conversion or otherwise;

  
 (xi) effect any reclassification or other
change of any stock, or any recapitalization of the Corporation; 
  
 (xii) permit any subsidiary to issue or sell, or obligate itself to issue or sell, except to the Corporation or any of its wholly-owned subsidiaries, any stock of such subsidiary; 
  
 (xiii) change the authorized number of directors of the
Corporation, or the number as to which the Preferred Stock has special voting rights, or the manner in which the Preferred Stock may exercise its special voting rights; 
  
 (xiv) effect any consolidation or merger involving the Corporation or any of its subsidiaries (not including
a consolidation or merger involving only the Corporation and one or more of its wholly-owned subsidiaries and no other entities, or a consolidation or merger involving only two or more of the Corporation’s wholly-owned subsidiaries and no other
entities); or 
  
 (xv) effect any transaction or
series of transactions by which the Corporation issues securities having voting power in excess of fifty percent (50%) of the total voting power of all securities of the Corporation immediately prior to such transaction or transactions, or otherwise
having the effect of transferring voting power in excess of fifty percent (50%) of the total voting power of all securities of the Corporation immediately prior to such transaction or transactions (for purposes of determining voting power for this
subsection, all securities convertible into Common Stock shall be assumed to have 
  

 19 

 been converted, and all options, warrants and other rights to acquire Common Stock or other securities
convertible into Common Stock, whether then or at some time in the future, shall be assumed to have been exercised). 
  
 (b) Notwithstanding any other provision of this Certificate of Incorporation or the Corporation’s Bylaws to the contrary, written notice of any
action specified in Subsection 4(a) shall be given to each holder of Preferred Stock entitled to vote or consent with respect to such action at least twenty (20) days before the date on which the books of the Corporation shall close or a record
shall be taken with respect to such proposed action, or, if there shall be no such date, at least twenty (20) days before the date when such proposed action is scheduled to take place. Any holder of outstanding shares of Preferred Stock may waive
any notice required by this Subsection 4(b) by a written document specifically indicating such waiver. 
  
 Section 5. Voting Rights. 
  
 (a) Voting by Preferred Stock and Common Stock. Except as otherwise required by law or set forth in this Certificate of Incorporation, the holders
of Series A Preferred Stock and Series B Preferred Stock shall be entitled to notice of any meeting of stockholders and shall vote together with the holders of Common Stock as a single class upon any matter submitted to the stockholders for a vote.
With respect to all questions as to which, by law or by this Certificate of Incorporation, stockholders are required to vote by classes or series, each of the Series A Preferred Stock and Series B Preferred Stock shall vote as separate classes apart
from the Common Stock. Shares of Common Stock, Series A Preferred Stock and Series B Preferred Stock shall entitle the holders thereof to the following number of votes on any matter as to which they are entitled to vote: 
  
 (i) holders of Common Stock shall have one vote per share; and 

 
 (ii) holders of Series A Preferred Stock and Series B Preferred Stock
shall have that number of votes per share as is equal to the number of shares of Common Stock (including fractions of a share) into which each such share of Series A Preferred Stock or Series B Preferred Stock (as the case may be) held by such
holder could be converted on the date for determination of stockholders entitled to vote at the meeting or on the date of any written consent. 
  
 (b) Election of Directors. 
  
 (i) At each election of the Corporation’s directors, the holders of a majority in interest of the then issued and outstanding shares of Series A
Preferred Stock (voting as a separate single class) will elect two (2) directors. 
  
 (ii) At each election of the Corporation’s directors, the holders of a majority in interest of the then issued and outstanding shares of Series B Preferred Stock (voting as a separate single class) will elect two
(2) directors. 
  
 (iii) At each election of the
Corporation’s directors, the holders of a majority in interest of the then issued and outstanding shares of Common Stock (voting as a separate single 

  

 20 

 
class, and excluding shares of Preferred Stock convertible into shares of Common Stock) will elect three (3) directors. 
  
 (iv) At each election of the Corporation’s directors, the holders of a
majority in interest of the Common Stock, Series A Preferred, and Series B Preferred (voting as a single class on an as-converted basis), will elect one (1) director. 
  
 (v) Notwithstanding any Bylaw provisions to the contrary, only the stockholders entitled to elect a particular director
shall be entitled to remove such director or to fill a vacancy in the seat formerly held by such director, all in accordance with the applicable provisions under Delaware law. 
  
 (c) Number of Board of Directors. Any provision of the Bylaws of the Corporation to the contrary notwithstanding, the
number of directors constituting the entire Board of Directors of the Corporation may not be increased above eight (8) without the prior written consent of the holders of at least a majority of the then issued and outstanding shares of Series A
Preferred Stock and Series B Preferred Stock (voting as a single class). 
  
 (d) Calling of Stockholder Meetings. In addition to any rights which may be available under the Corporation’s Bylaws or otherwise under law, the holders of not less than twenty-five percent (25%) in voting
power of the then issued and outstanding shares of Series A Preferred Stock and Series B Preferred Stock (voting as a single class) shall be entitled to call meetings of the stockholders of the Corporation. Within five (5) business days after
written application by such holders of Preferred Stock, the President or Secretary, or such other officer of the Corporation as may be authorized in the Bylaws of the Corporation to give notice of meetings of stockholders of the Corporation, shall
notify each stockholder of the Corporation entitled to such notice of the date, time, place and purpose of such meeting. No meeting of stockholders called pursuant to this Subsection 5(d) shall take place more than fourteen (14) days after the date
notice of such meeting is given. 
  
 (e) Vacancies on
Board. 
  
 (i) In the case of any vacancy in the office of a
director occurring among the directors elected by the holders of any series of Preferred Stock voting as a separate single class, the remaining director or directors so elected by the holders of such series of Preferred Stock may, by affirmative
vote of a majority thereof (or the remaining director so elected if there is but one) elect a successor or successors to hold the office for the unexpired term of the director or directors whose place or places shall be vacant. If there is no
director remaining who had been elected by the holders of such series of Preferred Stock, then the holders of a majority of the shares of such series of Preferred Stock shall elect a successor or successors to hold the office for the unexpired term
of the director or directors whose place or places shall be vacant. 
  
 (ii) In the case of any vacancy in the office of a director occurring among the directors elected by the holders of the Common Stock voting as a separate single class, the remaining director or directors so elected by the holders of the
Common Stock may, by affirmative vote of a majority thereof (or the remaining director so elected if there is but one) elect a successor or successors to hold the office for the unexpired term of the director or 
  

 21 

 directors whose place or places shall be vacant. If there is no director remaining who had been elected by the holders of
the Common Stock, then the holders of a majority of the shares of the Common Stock shall elect a successor or successors to hold the office for the unexpired term of the director or directors whose place or places shall be vacant. 
  
 (f) Termination of Certain Voting Rights. The method for election of
directors set forth in Subsection 5(b) above, the restriction on the size of the Corporation’s Board of Directors set forth in Subsection 5(c) above and the ability of the holders of Preferred Stock to call a stockholder meeting set forth in
Subsection 5(d) above shall all automatically terminate and be of no further force or effect upon the earliest to occur of (1) a Qualified Public Offering, (2) the merger or consolidation of the Corporation with or into any other corporation or
entity that results in all Preferred Stock being converted into Common Stock (unless stockholders of the Corporation immediately prior to such transaction are holders of at least a majority of the voting securities of the surviving or acquiring
corporation thereafter, and for the purposes of this calculation, voting securities of the surviving or acquiring corporation which any stockholder of the corporation owned immediately prior to such merger or consolidation as stockholders of another
party to the transaction shall be disregarded) or (3) when less than 1,000,000 shares of Preferred Stock (excluding shares of Common Stock issued upon the conversion of any shares of Preferred Stock) are outstanding. 
  
 Section 6. Dividends. 
  
 (a) The holders of Preferred Stock shall be entitled to receive, when and if
declared by the Corporation’s Board of Directors, out of any funds legally available therefor, preferential non-cumulative dividends in cash at the rate of (i) five and four-hundredths cents ($0.0504) per share (as adjusted for any stock
dividends, combinations, splits, recapitalizations or the like with respect to such shares) per annum for each share of Series A Preferred Stock, and (ii) eleven and forty-four-hundredths cents ($0.1144) per share (as adjusted for any stock
dividends, combinations, splits, recapitalizations or the like with respect to such shares) per annum for each share of Series B Preferred Stock. Any such dividends shall be distributed ratably among the holders of Series A Preferred Stock
and Series B Preferred Stock in proportion to the full amount each such holder is otherwise entitled to receive under this Subsection 6(a). 
  
 (b) No dividends or other distributions (whether payable in cash, securities, property or other assets) shall be paid on any Common Stock until (i) all
dividends accrued or declared but unpaid on the Preferred Stock shall have been paid in full and (ii) in the event that the Corporation’s Board of Directors have not declared a dividend on the Preferred Stock during the then-current calendar
year, all dividends are paid in full on the Preferred Stock as if such Board had declared a dividend on the Preferred Stock pursuant to Subsection 6(a) above during the then-current calendar year. 
  
 (c) Subject to Subsection 6(b) above, dividends and distributions may be
declared and paid on Common Stock from funds lawfully available therefor as and when determined by the Board of Directors of the Corporation; provided, however, that when and as dividends and distributions are declared and paid on
shares of Common Stock, the Corporation shall declare and pay at the same time to each holder of Preferred Stock, in addition to that which may be paid to satisfy the conditions set forth in Subsection 6(b) above, a dividend or distribution equal to
the 
  

 22 

 dividend or distribution which would have been payable to such holder if the shares of Preferred Stock held by such
holder had been converted into Common Stock on the record date for the determination of holders of Common Stock entitled to receive such dividend or distribution. 
  
 (d) No dividends or distributions shall be declared or paid on the Common Stock or Preferred Stock except as set forth in
this Section 6. 
  
 (e) As used herein, “distribution”
means the transfer of cash or property without consideration, whether by way of dividend or otherwise (except a dividend in shares of Common Stock) or the purchase of shares of capital stock of the Corporation for cash or property. 
  
 (f) The prohibition on payment of dividends and other distributions set forth
in Subsection 6(d) above shall not apply to: 
  
 (i) Dividends
payable solely in the Common Stock of the Corporation approved by the board of directors (including each of the Preferred Directors); 
  
 (ii) Acquisitions of Common Stock by the Corporation at a price not greater than the amount paid by service providers for such shares upon termination of
their employment or services pursuant to agreements providing for the right of said repurchase, so long as such acquisition is approved by the board of directors (including each of the Preferred Directors); 
  
 (iii) Acquisitions of Common Stock by the Corporation pursuant to its right
of repurchase set forth in the Stock Repurchase Agreement, dated as of May 25, 2001, among the Corporation, Michael D. Hooven and Susan Spies; 
  
 (iv) Acquisitions of stock in exercise of the Corporation’s right of first refusal upon a proposed transfer approved by the board of directors
(including each of the Preferred Directors); or 
  
 (v) A
distribution pursuant to Section 1 above. 
  
 Section 7.
No Reissuance of Preferred Stock. No share or shares of Preferred Stock acquired by the Corporation by reason of redemption, purchase, conversion or otherwise shall be reissued, and all such shares shall be cancelled, retired and eliminated
from the shares which the Corporation shall be authorized to issue. 
  
 Section 8. Residual Rights. All rights accruing to the outstanding shares of the Corporation not expressly provided for to the contrary herein shall be vested in the shares of Common Stock. 
  

 23 

 Section 9. Notices. All notices and other communications to any party required or permitted
to be sent pursuant to this Article IV (collectively, “Notices”) shall be contained in a written instrument addressed to such party at such party’s address as it appears on the books of the Corporation and shall be deemed given (a)
when delivered in person or duly sent by fax showing confirmation of receipt, (b) five (5) days after being duly sent by first class mail, postage prepaid (other than in the case of Notices to or from any non-U.S. resident, which Notices must be
sent in the manner specified in clause (a) or (c)), or (c) two (2) days after being duly sent by DHL, Fedex or other recognized express international courier service.

Committee shall be deemed, where appropriate, to be references to the Board during such period). After a Company IPO, the Committee shall have all rights and powers exclusively to administer the Plan (and references herein to the Board shall be
deemed, where appropriate, to be references to the Committee during such period). 
  
 (b) The Board and/or the Committee shall have the power, subject to, and within the limitations of, the express provisions of the Plan: 
  
 (1) To determine from time to time which of the persons eligible under the Plan shall be granted Options; when
and how each Option shall be granted; whether an Option will be an Incentive Stock Option or a Nonstatutory Stock Option; the provisions of each Option granted (which need not be identical), including the time or times such Option may be exercised
in whole or in part; and the number of shares for which an Option shall be granted to each such person. 
  
 (2) To construe and interpret the Plan and Options granted under it, and to establish, amend and revoke rules and regulations for its
administration. The Committee, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan or in any Option Agreement, in a manner and to the extent it shall deem necessary or expedient to make the Plan fully
effective. 
  
 (3) To amend the Plan or an Option as
provided in Section 11. 
  
 (4) Generally, to
exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the best interests of the Company which are not in conflict with the provisions of the Plan. 
  
 (c) Subject to subsection 3(a), the Board may delegate
administration of the Plan to the Committee, which Committee shall at all times consist of two (2) or more Board members. The Board shall have the power at any time to fill vacancies in or to change the membership of such Committee, and prior to a
Company IPO, to discharge such Committee. The Committee shall select one of its members as its chairman and shall hold its meetings at such time and at such places as it shall deem advisable. A majority of such Committee shall constitute a quorum
and such majority shall determine its action. Any action may be taken without a meeting by written consent of all the members of the Committee. The Committee shall keep minutes of its proceedings and shall report the same to the Board at the next
succeeding meeting. To the extent practicable, at all times after a Company IPO, the members of the Committee shall be “outside directors” as defined in the regulations under Section 162(m) of the Code and “non-employee
directors” as defined by Regulation 240.16b-3 under the Exchange Act. 
  

 3 

 4. SHARES SUBJECT TO THE PLAN.

  
 (a) Subject to the provisions of Section 10
relating to adjustments upon changes in stock, the stock that may be sold pursuant to Options shall not exceed an aggregate of Five Million One Hundred Thousand (5,100,000) shares of the Company’s common stock, par value $0.0001 per share
(“Common Stock”). If any Option shall for any reason expire or otherwise terminate, in whole or in part, without having been exercised in full, the stock not purchased under such Option shall revert to and again become available for
issuance under the Plan. 
  
 (b) The stock subject
to the Plan may be unissued shares or reacquired shares, bought on the market or otherwise. 
  
 5. ELIGIBILITY. 
  
 (a) Incentive Stock Options may be granted only to Employees. Nonstatutory Stock Options may be granted only to Employees, Directors or Consultants. 
  
 (b) No person shall be eligible for the grant of an Incentive
Stock Option if, at the time of grant, such person owns (or is deemed to own pursuant to Section 424(d) of the Code) stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or of any of
its Affiliates (“10% Owner”) unless the exercise price of such Incentive Stock Option is at least one hundred ten percent (110%) of the Fair Market Value of such stock at the date of grant and the Incentive Stock Option is not
exercisable after the expiration of five (5) years from the date of grant. To the extent required by applicable law, the provisions of this subsection 5(b) shall also apply to the grant of a Nonstatutory Stock Option granted to a ten percent (10%)
stockholder described in the preceding sentence. 
  
 6.
OPTION PROVISIONS. 
  
 Each
Option shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The provisions of separate Options need not be identical, but each Option shall include (through incorporation of provisions hereof by
reference in the Option or otherwise) the substance of each of the following provisions: 
  
 (a) Term. No Option shall be exercisable after the expiration of ten (10) years from the date it was granted (or five (5) years in the case of an Incentive Option granted to a 10% owner).

  
 (b) Price. The exercise price of each
Incentive Stock Option shall be not less than one hundred percent (100%) of the Fair Market Value on the date of grant (or in the case of a 10% Owner, the exercise price of an Incentive Stock Option must be at least one hundred ten percent (110%) of
the Fair Market Value of such stock at the date of grant). Notwithstanding the foregoing, the Board may grant an Option with an exercise price lower than that set forth above if such Option is granted as part of a transaction pursuant to section
424(a) of the Code. 
  

 4 

 (c) Consideration. The purchase price of stock acquired pursuant to an Option shall
be paid, to the extent permitted by applicable statutes and regulations, (i) by cash or check, (ii) if permitted by the Company, by delivery and assignment of shares of Common Stock having a Fair Market Value equal to the exercise price, (iii) if
permitted by the Company, by a promissory note, or (iv) by a combination of (i), (ii) and (iii); provided, however, in the event of payment of the exercise price for the shares of Common Stock by method (ii) or (iv) above, the shares
of Common Stock so surrendered, if originally issued to the Optionee upon exercise of a stock option(s) granted by the Company, shall have been held by the Optionee for more than six (6) months. 
  
 (d) Transferability. An Incentive Stock Option shall not
be transferable except by will or by the laws of descent and distribution, and shall be exercisable during the lifetime of the person to whom the Incentive Stock Option is granted only by such person. A Nonstatutory Stock Option shall only be
transferable by the Optionee upon such terms and conditions as set forth in the Option Agreement for such Nonstatutory Option, as the Board or Committee shall determine in its discretion, except that each Nonstatutory Stock Option may be transferred
to the spouse, children and lineal descendants of the Optionee (or to a trust created solely for the benefit of the Optionee and the foregoing persons) or to an organization exempt from taxation pursuant to Section 501(c)(3) of the Code or to which
tax deductible charitable contributions may be made under Section 170 of the Code (excluding such organizations classified as private foundations under applicable regulations and rulings). The person to whom the Nonstatutory Option is granted may,
by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Optionee, shall thereafter be entitled to exercise the Option. 
  
 (e) Vesting. The total number of shares of stock subject
to an Option may, but need not, be allotted in periodic installments (which may, but need not, be equal). The Option Agreement may provide that from time to time during each of such installment periods, the Option may become exercisable
(“vest”) with respect to some or all of the shares allotted to that period, and may be exercised with respect to some or all of the shares allotted to such period and/or any prior period as to which the Option became vested but was not
fully exercised. To the extent required by applicable law, Options shall vest at the rate of at least twenty percent (20%) per year over five (5) years from the date the option is granted. The Option may be subject to such other terms and conditions
on the time or times when it may be exercised (which may be based on performance or other criteria) as the Board may deem appropriate. The provisions of this subsection 6(e) are subject to any Option provisions governing the minimum number of shares
as to which an Option may be exercised. 
  
 (f) Securities Law Compliance. The Company may require any Optionee, or any person to whom an Option is transferred under subsection 6(d), as a condition of exercising any such Option: (1) to give written assurances
satisfactory to the Company as to the Optionee’s knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and
business matters, and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Option; and (2) to give written assurances satisfactory to the Company stating that such
person is acquiring the stock subject to the 
  

 5 

 Option for such person’s own account and not with any present intention of selling or otherwise distributing the
stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (i) the issuance of the shares upon the exercise of the Option has been registered under a then currently effective registration
statement under the Securities Act of 1933, as amended (the “Securities Act”), or (ii) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under
the then applicable securities laws. The Company may require the Optionee to provide such other representations, written assurances or information which the Company shall determine is necessary, desirable or appropriate to comply with applicable
securities and other laws as a condition of granting an Option to such Optionee or permitting the Optionee to exercise such Option. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as
such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the stock. 
  
 (g) Termination of Continuous Status as an Employee, Director or Consultant. In the event an
Optionee’s Continuous Status as an Employee, Director or Consultant terminates (other than upon the Optionee’s death or disability), the Optionee may exercise his or her Option (to the extent that the Optionee was entitled to exercise it
as of the date of termination) but only within such period of time ending on the earlier of (i) the date three (3) months after the termination of the Optionee’s Continuous Status as an Employee, Director or Consultant, or such longer or
shorter period specified in the Option Agreement (which shall be at least thirty (30) days, if required by applicable law) or (ii) the expiration of the term of the Option as set forth in the Option Agreement. Finally, an Optionee’s Option
Agreement may also provide that if the exercise of the Option following the termination of the Optionee’s Continuous Status as an Employee, Director or Consultant (other than upon the Optionee’s death or disability) would be prohibited at
any time solely because the issuance of shares would violate the registration requirements under the Securities Act, then the Option shall terminate on the later of (i) the expiration of the term of the Option set forth in the first sentence of this
Section 6(g), or (ii) the expiration of a period of three (3) months after the termination of the Optionee’s Continuous Status as an Employee, Director or Consultant (other than upon the Optionee’s death or disability) during which the
exercise of the Option would not be in violation of such registration requirements. 
  
 (h) Disability of Optionee. In the event an Optionee’s Continuous Status as an Employee, Director or Consultant terminates as a result of the Optionee’s disability, the Optionee may
exercise his or her Option (to the extent that the Optionee was entitled to exercise it as of the date of termination), but only within such period of time ending on the earlier of (i) the date twelve (12) months following such termination (or such
longer or shorter period specified in the Option Agreement), or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionee does not exercise his or her Option within the time specified
herein, the Option shall terminate, and the shares covered by such Option shall revert to and again become available for issuance under the Plan. 
  
 (i) Death of Optionee. In the event of the death of an Optionee during, or within a period specified in the Option Agreement after
the termination of, the Optionee’s Continuous

 Status as an Employee, Director or Consultant, the Option may be exercised (to the extent the Optionee was entitled to
exercise the Option as of the date of death) by the Optionee’s estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a person designated to exercise the option upon the Optionee’s death pursuant
to subsection 6(d), but only within the period ending on the earlier of (i) the date twelve (12) months following the date of death (or such longer or shorter period specified in the Option Agreement), or (ii) the expiration of the term of such
Option as set forth in the Option Agreement. If, after death, the Option is not exercised within the time specified herein, the Option shall terminate, and the shares covered by such Option shall revert to and again become available for issuance
under the Plan. 
  
 (j) Early Exercise. The
Option may, but need not, include a provision whereby the Optionee may elect at any time while an Employee, Director or Consultant to exercise the Option as to any part or all of the shares subject to the Option prior to the full vesting of
the Option. Any unvested shares so purchased shall be subject to a repurchase right in favor of the Company or to any other restriction the Board determines to be appropriate. 
  
 (k) Right of Repurchase. The Option may, but need not, include a provision whereby the Company may
elect, prior to the date of the first registration of an equity security of the Company under Section 12 of the Exchange Act, to repurchase all or any part of the Optionee’s shares acquired pursuant to exercising the Option. 
  
 (l) Right of First Refusal. 
  
 (1) Sale Notice. Except as provided in Section 6(d) hereof, and only
prior to a Company IPO, if at any time any Optionee (“Offering Stockholder”) desires to sell or otherwise transfer any shares of Common Stock acquired pursuant to the exercise of any Options granted hereunder (“Offered
Securities”), to any person or entity pursuant to a bona fide offer to purchase from such person or entity (“Offering Purchaser”), such Offering Stockholder shall notify the Company (the “Notice”) of his, her or its
intention to do so by giving the Company written notice disclosing: (i) the name of the proposed transferee of the shares; (ii) the certificate number and number of shares proposed to be transferred; (iii) the proposed price; (iv) all other terms of
the proposed transaction; and (v) a written copy of the proposed offer. The Notice shall offer to sell to the Company the Offered Securities free and clear of any and all liens and encumbrances, at a price and on such other terms and conditions, if
any, not less favorable to the Company than those described in the Notice. In the event all or any part of the consideration shall be other than cash, the price shall mean the Fair Market Value of such consideration (determined in good faith by the
Board of Directors (which will be deemed final and binding on the parties absent manifest error or fraud)). 
  
 (2) Purchase by the Company. During the 45-day period after receipt of such Notice, the Company shall have the first right to purchase all or any
portion of the Offered Securities at the same price and on the same terms (to the extent practicable) as contained in such Notice (and the Offering Stockholder shall cooperate in all respects with such purchase) by sending written notice of the
number of Offered Securities it has determined to purchase to the Offering Stockholder.

 (3) Assignability of the Right of First Refusal. The Company may assign its right of first refusal
as set forth in this Section 6(1). 
  
 (m)
Withholding. To the extent provided by the terms of an Option Agreement, the Optionee may satisfy any federal, state or local tax withholding obligation relating to the exercise of such Option by any of the following means or by a combination
of such means: (1) tendering a cash payment; (2) authorizing the Company to withhold shares from the shares of the common stock otherwise issuable to the Optionee as a result of the exercise of the Option; or (3) delivering to the Company owned and
unencumbered shares of the common stock of the Company. 
  
 7.
COVENANTS OF THE COMPANY. 
  
 (a) During the terms of the Options, the Company shall keep available at all times the number of shares of stock required to satisfy such Options. 
  
 (b) The Company shall seek to obtain from each regulatory
commission or agency having jurisdiction over the Plan such authority as may be required to issue and sell shares of stock upon exercise of the Options; provided, however, that this undertaking shall not require the Company to register, under
the Securities Act, any of the Plan, any Option or any stock issued or issuable pursuant to any such Option. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority which counsel for
the Company deems necessary for the lawful issuance and sale of stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell stock upon exercise of such Options unless and until such authority is obtained.

  
 (c) Prior to the Company becoming a reporting
company under the Exchange Act, the Company shall provide each Optionee with a copy of the audited balance sheet of the Company for each fiscal year ended as of December 31, and the related audited statements of income, retained earnings,
stockholders’ equity and changes in financial position of the Company for such year, on the later of (i) thirty (30) days after the completion of the audit for the relevant fiscal year and (ii) thirty (30) days after an Optionee’s request
in writing to the Company requesting such information. 
  
 8.
USE OF PROCEEDS FROM STOCK. 
  
 Proceeds from the sale of stock pursuant to Options shall constitute general funds of the Company. 
  
 9. MISCELLANEOUS. 
  
 (a) The Board shall have the power to accelerate the time at
which an Option may first be exercised or the time during which an Option or any part thereof will vest, notwithstanding the provisions in the Option stating the time at which it may first be exercised or the time during which it will vest.

  

 8 

 (b) Neither an Optionee nor any person to whom an Option is transferred under subsection
6(d) shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares subject to such Option unless and until such person has satisfied all requirements for exercise of the Option pursuant to its terms.

  
 (c) Nothing in the Plan or any instrument
executed or Option granted pursuant thereto shall confer upon any Employee, Director, Consultant or Optionee any right to continue in the employ of the Company or any Affiliate (or to continue acting as a Director or Consultant) or shall affect the
right of the Company or any Affiliate to terminate the employment of any Employee with or without cause, the right of the Company’s Board of Directors and/or the Company’s shareholders to remove any Director pursuant to the terms of the
Company’s stockholders’ agreement, the Company’s By-Laws and applicable law, or the right to terminate the relationship of any Consultant pursuant to the terms of such Consultant’s agreement with the Company or any Affiliate.

  
 (d) To the extent that the aggregate Fair Market
Value (determined at the time of grant) of stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionee during any calendar year under all plans of the Company and its Affiliates exceeds One Hundred Thousand
Dollars ($100,000), the Options or portions thereof which exceed such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options. 
  
 10. ADJUSTMENTS UPON CHANGES IN STOCK. 

 
 (a) If any change is made in the stock subject to the Plan,
or subject to any Option (through merger, consolidation, reorganization, reincorporation, recapitalization, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in
corporate structure or other transaction not involving the receipt of consideration by the Company), the Plan will be appropriately adjusted in the class(es) and maximum number of shares subject to the Plan pursuant to subsection 4(a), and the
outstanding Options will be appropriately adjusted in the class(es) and number of shares and price per share of stock subject to such outstanding Options. Such adjustments shall be made by the Board or Committee, the determination of which shall be
final, binding and conclusive. (The conversion of any convertible securities of the Company shall not be treated as a “transaction not involving the receipt of consideration by the Company.”) 
  
 (b) In the event (any such event, a “Change of Control
Event”) of: (1) a sale of all or substantially all of the assets of the Company; (2) a merger or consolidation in which the Company is not the surviving corporation; (3) a reverse merger in which the Company is the surviving corporation but the
shares of the Company’s common stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise; or (4) the acquisition by any person, entity or
group within the meaning of Section 13(d) or 14(d) of the Exchange Act, or any comparable successor provisions (excluding any employee benefit plan, or related trust, sponsored or maintained by the Company or any Affiliate of the Company) of the
beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act or comparable successor rule) of outstanding securities of the Company representing at least eighty percent (80%) of the combined voting power entitled to vote
in the election of directors, then such Options shall become fully vested immediately prior to the closing of such transaction.

 11. AMENDMENT OF THE PLAN AND
OPTIONS. 
  
 (a) The Board at
any time, and from time to time, may amend the Plan. However, except as provided in Section 10 relating to adjustments upon changes in stock, no amendment shall be effective unless approved by the shareholders of the Company within twelve (12)
months after the Board’s adoption of the amendment where the amendment requires shareholder approval in order for the Plan to satisfy the requirements of Section 422 of the Code (including an increase in the number of shares reserved for
issuance under the Plan). 
  
 (b) The Board may, in
its sole discretion, submit any other amendment to the Plan for shareholder approval. 
  
 (c) It is expressly contemplated that the Board may amend the Plan in any respect the Board deems necessary or advisable to provide Optionees with the maximum benefits provided or to be provided under
the provisions of the Code and the regulations promulgated thereunder relating to Incentive Stock Options and/or to bring the Plan and/or Incentive Stock Options granted under it into compliance therewith. 
  
 (d) Rights and obligations under any Option granted before
amendment of the Plan shall not be impaired by any amendment of the Plan unless (i) the Company requests the consent of the person to whom the Option was granted and (ii) such person consents in writing. 
  
 (e) The Board at any time, and from time to time, may amend the
terms of any one or more Options; provided, however, that the rights and obligations under any Option shall not be impaired by any such amendment unless (i) the Company requests the consent of the person to whom the Option was granted and
(ii) such person consents in writing. 
  
 12. TERMINATION
OR SUSPENSION OF THE PLAN. 
  
 (a) The Board may suspend or terminate the Plan at any time. Unless sooner terminated, the Plan shall terminate ten (10) years from the date
the Plan is adopted by the Board or approved by the stockholders of the Company, whichever is earlier. No Options may be granted under the Plan while the Plan is suspended or after it is terminated. 
  
 (b) Rights and obligations under any Option granted while the
Plan is in effect shall not be impaired by suspension or termination of the Plan, except with the written consent of the person to whom the Option was granted. 
  

13. EFFECTIVE DATE OF PLAN. 
  
 The Plan shall become effective as determined by the Board, but no Options granted under the Plan shall be exercised unless
and until the Plan has been approved by the stockholders of the Company, which approval shall be within twelve (12) months after the date the Plan is adopted by the Board. 
  

 10 

 14. APPLICABLE LAW. 
  
 The validity, interpretation and enforcement of this Plan shall be governed
in all respects by the laws of the State of Delaware (without giving effect to any choice of law or conflict of law rules or provisions that would cause the application of the laws of any jurisdiction other than the State of Delaware) and the United
States of America.
