A. Authorization of Stock. This corporation is authorized to issue two classes of stock to be designated, respectively, common stock and preferred stock. The total number of shares that this corporation is authorized to issue is 130,114,361. The total number of shares of common stock authorized to be issued is 71,000,000, par value $0.0001 per share (the “Common Stock”). The total number of shares of preferred stock authorized to be issued is 59,114,361 (the “Preferred Stock”), of which 22,601,626 shares, par value $0.0001 per share, are designated as “Series A Preferred Stock”, 9,309,492 shares, par value $0.0001 per share, are designated as “Series B Preferred Stock” and 27,203,243 shares, par value $0.001 per share, are designated as “Series C Preferred Stock.”

B. Rights, Preferences and Restrictions of Preferred Stock. The rights, preferences, privileges and restrictions granted to and imposed on the Preferred Stock are as set forth below in this Article IV(B).

1. Dividend Provisions.

(a) The holders of shares of Preferred Stock shall be entitled to receive dividends on a pari passu basis, out of any assets legally available therefor, prior and in preference to any declaration or payment of any dividend (payable other than in Common Stock or other securities and rights convertible into or entitling the holder thereof to receive, directly or indirectly, additional shares of Common Stock) on the Common Stock of this corporation at a rate of 8.0% of the Original Issue Price (as defined below) per annum, payable when, as and if declared by this corporation’s board of directors (the “Board of Directors”). Such dividends shall not be cumulative. The holders of the outstanding Preferred Stock can waive any dividend preference that such holders shall be entitled to receive under this Section 1 upon the affirmative vote or written consent of the holders of at least seventy percent (70%) of the shares of Series B Preferred Stock and Series C Preferred Stock then outstanding (voting together as a single class and not as separate series, and on an as-converted basis) (the “Requisite Holders”).

(b) After payment of such dividends, any additional dividends or distributions shall be distributed among all holders of Common Stock and Preferred Stock in proportion to the number of shares of Common Stock that would be held by each such holder if all shares of Preferred Stock were converted to Common Stock at the then effective Conversion Rate (as defined below). For this purpose, each holder of shares of Preferred Stock is to be treated as holding the greatest whole number of shares of Preferred Stock held by such holder pursuant to Section 4.

(c) Whenever a dividend provided for in this Section 1 will be payable in property other than cash, the value of such dividend will be deemed to be the fair market value of such property as determined in good faith by the Board of Directors, including the approval of a majority of the Preferred Directors who are then seated (the “Requisite Preferred Director Vote”).

(d) Notwithstanding the foregoing, in the event that this corporation declares a Special Dividend (as defined below), the proceeds of such Special Dividend shall be paid in accordance with Section 2 below and not this Section 1. A “Special Dividend” shall mean the payment of a dividend or other distribution of funds of this corporation to its stockholders where such funds were obtained from or are to be paid in connection with (i) the sale by this corporation of its equity securities (other than in connection with an initial public offering of this

corporation’s Common Stock) or incurrence of indebtedness for borrowed money outside of the ordinary course of business; (ii) the sale, lease, transfer, license or other disposition, in a single transaction or series of related transactions, by this corporation or any subsidiary of this corporation of a material portion of this corporation’s and its subsidiaries’ assets taken as a whole; or (iii) any other material transaction or series of related transactions that collectively would be material outside of the ordinary course of business; provided, however, that a Special Dividend shall not include (A) the distribution of funds or assets resulting from a Liquidation Event (as defined below) or (B) the distribution of funds or assets from this corporation’s cash flow from operation of this corporation’s business in the ordinary course.

2. Liquidation Preference.

(a) In the event of any Liquidation Event (as defined below), either voluntary or involuntary, or any Special Dividend, the holders of each series of Preferred Stock shall be entitled to receive, on a pari passu basis, out of the proceeds or assets of this corporation available for distribution to its stockholders (the “Proceeds”), prior and in preference to any distribution of the Proceeds of such Liquidation Event or Special Dividend to the holders of Common Stock by reason of their ownership thereof, an amount per share equal to the sum of the applicable Original Issue Price (as defined below) for such series of Preferred Stock, plus declared but unpaid dividends on such share (“Liquidation Amount”). If, upon the occurrence of such event, the Proceeds thus distributed among the holders of the Preferred Stock shall be insufficient to permit the payment to such holders of the full aforesaid preferential amounts, then the entire Proceeds legally available for distribution shall be distributed ratably among the holders of the Preferred Stock in proportion to the full preferential amount that each such holder is otherwise entitled to receive under this subsection (a). For purposes of this Amended and Restated Certificate of Incorporation (this “Restated Certificate of Incorporation”), “Original Issue Price” shall mean $1.5375 per share for each share of the Series A Preferred Stock, $9.0251 per share for each share of Series B Preferred Stock and $6.7688 per share for each share of Series C Preferred Stock (in each case, as adjusted for any stock splits, stock dividends, combinations, subdivisions, recapitalizations or the like with respect to such series of Preferred Stock).

(b) Upon completion of the distribution required by subsection (a) of this Section 2, all of the remaining Proceeds available for distribution to stockholders shall be distributed among the holders of Common Stock pro rata based on the number of shares of Common Stock held by each.

(c) 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 or Special Dividend, 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 or Special Dividend 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. In the event of more than one distribution pursuant to this Section 2, including distributions of Special Dividends and any proceeds of a Liquidation Event, such distributions shall be allocated among the holders of capital stock of this corporation in accordance with this Sections 2(a) and 2(b) after taking into account payment of the prior distributions so as to reach the result that would have occurred if all such proceeds had been distributed in a single event (for the purposes of example only, if this corporation first paid a Special Dividend of $10 million and subsequently paid a second Special Dividend of $20 million, the second Special Dividend would be distributed so as to equal the same results as if a single $30 million distribution had been made under this Section 2).

(d) (i) For purposes of this Section 2, a “Liquidation Event” shall include (A) the closing of the sale, lease, transfer, exclusive license or other disposition of all or substantially all of this corporation’s assets, (B) the consummation of the merger or consolidation of this corporation with or into another entity (except a merger or consolidation in which the holders of capital stock of this corporation immediately prior to such merger or consolidation continue to hold a majority of the voting power of the capital stock of this corporation or the surviving or acquiring entity immediately following such merger or consolidation in substantially the same proportions, and with substantially the same terms, as held immediately prior to such merger or consolidation, but expressly including such merger or consolidation with a publicly traded “special purpose acquisition company” or subsidiary of such company (collectively, a “SPAC”) to the extent such merger or consolidation with a SPAC is not a Qualifying SPAC Transaction (as defined below)), (C) the closing of the transfer (whether by merger, consolidation or otherwise), in one transaction or a series of related transactions, to a person or group of affiliated persons (other than an underwriter of this corporation’s securities), of this corporation’s securities if, after such closing, such person or group of affiliated persons would hold fifty percent (50%) or more of the then outstanding voting stock of this corporation (or the surviving or acquiring entity) or (D) a liquidation, dissolution or winding up of this corporation; provided, however, that a transaction shall not constitute a Liquidation Event if its sole purpose is to change the state of this corporation’s incorporation or to create a holding company that will be owned in substantially the same proportions by the persons who held this corporation’s securities immediately prior to such transaction. Notwithstanding the prior sentence, the sale by this corporation of its equity securities in a bona fide financing transaction conducted in accordance with Section 6 of this Article IV(B) shall not be deemed a “Liquidation Event.” The treatment of any particular transaction or series of related transactions as a Liquidation Event may be waived by the vote or written consent of the Requisite Holders.

(ii) In any Liquidation Event or Special Dividend, if Proceeds received by this corporation or its stockholders is other than cash, its value will be deemed its fair market value. Any securities shall be valued as follows:

(A) Securities not subject to investment letter or other similar restrictions on free marketability covered by (B) below:

(1) If traded on a securities exchange, the value shall be deemed to be the average of the closing prices of the securities on such exchange over the twenty (20) trading-day period ending three (3) trading days prior to the closing of the Liquidation Event or Special Dividend;

(2) If actively traded over-the-counter, the value shall be deemed to be the average of the closing bid or sale prices (whichever is applicable) over the twenty (20) trading-day period ending three (3) trading days prior to the closing of the Liquidation Event or Special Dividend; and

(3) If there is no active public market, the value shall be the fair market value thereof, as determined in good faith by Requisite Preferred Director Vote.

(B) 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 to make an appropriate discount from the market value determined as above in (A)(1), (A)(2) or (A)(3) to reflect the approximate fair market value thereof, as determined in good faith by Requisite Preferred Director Vote.

(C) The foregoing methods for valuing non-cash consideration to be distributed in connection with a Liquidation Event or Special Dividend shall, with the appropriate approval of the definitive agreements governing such Liquidation Event or Special Dividend by the stockholders under the General Corporation Law and Section 6 of this Article IV(B), be superseded by the determination of such value set forth in the definitive agreements governing such Liquidation Event or Special Dividend, as applicable.

(iii) In the event the requirements of this Section 2 are not complied with, this corporation shall forthwith either:

(A) cause the closing of such Liquidation Event or Special Dividend to be postponed until such time as the requirements of this Section 2 have been complied with; or

(B) cancel such transaction, in which event the rights, preferences and privileges of the holders of the Preferred Stock shall revert to and be the same as such rights, preferences and privileges existing immediately prior to the date of the first notice referred to in subsection 2(d)(iv) hereof.

(iv) This corporation shall give each holder of record of Preferred Stock written notice of such impending Liquidation Event or Special Dividend not later than twenty (20) days prior to the stockholders’ meeting called to approve such transaction, or twenty (20) days prior to the closing of such transaction, whichever is earlier, and shall also notify such holders in writing of the final approval of such transaction. The first of such notices shall describe the material terms and conditions of the impending transaction and the provisions of this Section 2, and this corporation shall thereafter give such holders prompt notice of any material changes. The transaction shall in no event take place sooner than twenty (20) days after this corporation has given the first notice provided for herein or sooner than ten (10) days after this corporation has given notice of any material changes provided for herein; provided, however, that subject to compliance with the General Corporation Law such periods may be shortened upon the written consent of the Requisite Holders.

(e) In the event of a Liquidation Event referred to in Section 2(d)(i)(A), if this corporation does not effect a dissolution under the General Corporation Law within ninety (90) days after such Liquidation Event, then (i) this corporation shall send a written notice to each holder of Preferred Stock no later than the ninetieth (90^th) day after the Liquidation Event advising such holders of their right (and the requirements to be met to secure such right) pursuant to the terms of the following clause (ii) to require the redemption of such shares of Preferred Stock, and (iii) if the Requisite Holders so request in a written instrument delivered to this corporation not later than one hundred twenty (120) days after such Liquidation Event, this corporation shall use the consideration received for such Liquidation Event (net of any retained liabilities associated with the assets sold or technology licensed, as determined in good faith by Requisite Preferred Director Vote), together with any other assets for distribution to stockholders, all to the extent permitted by Delaware law governing distributions to stockholders (the “Available Proceeds”), on the one hundred fiftieth (150^th) day after such Liquidation Event (the “LE Redemption Date”), to redeem all outstanding shares of Preferred Stock at a price per share equal to the Liquidation Amount; provided, that if the definitive agreements governing such Liquidation Event contain contingent indemnification obligations on the part of this corporation and prohibit this corporation from distributing all or a portion of the Available Proceeds while such indemnification obligations remain outstanding, then the LE Redemption Date shall automatically be extended to the date that is ten (10) business days following the date on which such prohibition expires. Notwithstanding the foregoing, in the event of a redemption pursuant to the preceding sentence, if the Available Proceeds are not sufficient to redeem all outstanding shares of Preferred Stock, this corporation shall redeem a pro rata portion of each holder’s shares of Preferred Stock to the fullest extent of such Available Proceeds, based on the respective amounts which would otherwise be payable in respect of the shares to be redeemed if the Available Proceeds were sufficient to redeem all such shares, and shall redeem the remaining shares as soon as it may lawfully do so under Delaware law governing distributions to stockholders. Prior to the distribution or redemption provided for in this Section 2(e), this corporation shall not expend or dissipate the consideration received for such Liquidation Event, except to discharge expenses incurred in connection with such Liquidation Event or in the ordinary course of business.

(f) Following an election by the holders of Preferred Stock to demand redemption as provided in Section 2(e), this corporation shall promptly send written notice of the redemption pursuant to Section 2(e) (the “Redemption Notice”) to each holder of record of Preferred Stock stating (i) the number of shares of each series of Preferred Stock held by such holder as of the date of such election; (ii) the redemption date and the price at which shares of each series of Preferred Stock will be redeemed (the “Redemption Price”); (iii) the date on which the holder’s right to convert such shares terminates (as determined in accordance with Section 4(a)); and (iv) for holders of shares in certificated form, that the holder is to surrender to this corporation, in the manner and at the place designated, his, her or its certificate or certificates representing the shares of Preferred Stock to be redeemed.

(g) On or before the redemption date, each holder of shares of Preferred Stock, unless such holder has exercised his, her or its right to convert such shares as provided in Section 4, shall, if a holder of shares in certificated form, surrender the certificate or certificates representing such shares (or, if such registered holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to this corporation to indemnify this corporation against any claim that may be made against this corporation on account of the alleged loss, theft or destruction of such certificate) to this corporation, in the manner and at the place designated in the Redemption Notice, and thereupon the Redemption Price for such shares shall be payable to the order of the person whose name appears on such certificate or certificates as the owner thereof.

(h) If the Redemption Notice shall have been duly given, and if on the redemption date the Redemption Price payable upon redemption of the shares of Preferred Stock is paid or tendered for payment or deposited with an independent payment agent so as to be available therefor in a timely manner, then notwithstanding that any certificates evidencing any of the shares of Preferred Stock so called for redemption shall not have been surrendered, dividends with respect to such shares of Preferred Stock shall cease to accrue after the redemption date and all rights with respect to such shares shall forthwith after the redemption date terminate, except only the right of the holders to receive the Redemption Price without interest upon surrender of any such certificate or certificates therefor.

(i) Allocation of Contingent Consideration. In the event of a Liquidation Event pursuant to subsection 2(d)(i), if any portion of the consideration payable to the stockholders of this corporation is placed into escrow and/or is payable to the stockholders of this corporation subject to contingencies (“Additional Consideration”), the definitive agreement with respect to such deemed Liquidation Event shall provide that (i) the portion of such consideration that is not Additional Consideration (such portion, the “Initial Consideration”) shall be allocated among the holders of capital stock of this corporation in accordance with subsections 2(a) and 2(b) as if the Initial Consideration were the only consideration payable in connection with such deemed Liquidation Event and (ii) any Additional Consideration that becomes payable to the stockholders of this corporation upon release from escrow or satisfaction of contingencies shall be allocated among the holders of capital stock of this corporation in accordance with subsections 2(a) and 2(b) after taking into account the previous payment of the Initial Consideration as part of the same transaction. For the purposes of this subsection 2(i), consideration placed into escrow or retained as a holdback to be available for satisfaction of indemnification or similar obligations in connection with such deemed Liquidation Event shall be deemed to be Additional Consideration.

3. Redemption. The Preferred Stock is not redeemable at the option of the holder thereof except for redemption pursuant to Section 2(e).

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

(a) Right to Convert. Subject to Section 4A.1., each share of Preferred Stock shall be convertible, at the option of the holder thereof, at any time after the date of issuance of such share, at the office of this corporation or any transfer agent for such stock, into such number of fully paid and nonassessable shares of Common Stock as is determined by dividing the applicable Original Issue Price for such series by the applicable Conversion Price (as defined below) for such series (the conversion rate for a series of Preferred Stock into Common Stock is referred to herein as the “Conversion Rate” for such series), determined as hereafter provided, in effect on the date the certificate is surrendered for conversion. The initial “Conversion Price” per share for each series of Preferred Stock shall be the Original Issue Price applicable to such series; provided, however, that the Conversion Price for the Preferred Stock shall be subject to adjustment as set forth in subsection 4(d).

(b) Automatic Conversion. Each share of Preferred Stock shall automatically be converted into shares of Common Stock at the Conversion Rate at the time in effect for such series of Preferred Stock immediately upon the earlier of (i) immediately prior to the closing of this corporation’s sale of its Common Stock to the public at a price of at least $6.7688 per share (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Common Stock), in a firm commitment underwritten public offering pursuant to an effective registration statement on Form S-1 under the Securities Act of 1933, as amended, that results in at least $100,000,000 of gross proceeds and in connection with such offering the Common Stock is listed for trading on the Nasdaq Stock Market, the New York Stock Exchange or another exchange or marketplace approved by the Board of Directors, (ii) this corporation’s completion of a transaction or series of related transactions (by merger, or consolidation, share exchange or otherwise) with a SPAC in which the common stock or share capital of the SPAC or its successor or ultimate parent entity (collectively, the “Listed Entity”) is listed for trading on the Nasdaq Stock Market’s National Market, the New York Stock Exchange or another exchange or marketplace approved by the Board of Directors and, in connection with which (a) this corporation is valued in such SPAC transaction such that each share of Series C Preferred Stock will be exchanged for a share of capital stock of the Listed Entity with a per share value that is at least $6.7688 (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Common Stock) and (b) the Listed Entity, upon closing of such transaction, has unrestricted cash of an aggregate of at least $100,000,000 (the foregoing, a “Qualified SPAC Transaction”), (iii) the effectiveness of the registration statement in connection with the initial listing of the Common Stock (or other equity securities of this corporation) on the Nasdaq Stock Market’s National Market, the New York Stock Exchange or another exchange or marketplace approved by the Board of Directors by means of an effective registration statement filed by this corporation with the Securities and Exchange Commission, without a related underwritten offering of such Common Stock (or other equity securities) or (iv) the date, or the occurrence of an event, specified by vote or written consent or agreement of the Requisite Holders.

(c) Mechanics of Conversion. Before any holder of Preferred Stock shall be entitled to voluntarily convert the same into shares of Common Stock, such holder shall surrender the certificate or certificates therefor, duly endorsed, at the office of this corporation or of any transfer agent for the Preferred Stock, and shall give written notice to this corporation at its principal corporate office, of the election to convert the same and shall state therein the name or names in which the certificate or certificates for shares of Common Stock are to be issued. This corporation shall, as soon as practicable thereafter, issue and deliver at such office to such holder of Preferred Stock, or to the nominee or nominees of such holder, a certificate or certificates for the number of shares of Common Stock to which such holder shall be entitled as aforesaid. Such conversion shall be deemed to have been made immediately prior to the close of business on the date set forth for conversion in the written notice of the election to convert irrespective of the 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 such conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock as of

such date. If the conversion is in connection with an underwritten offering of securities registered pursuant to the Securities Act of 1933, as amended, the conversion may, at the option of any holder tendering 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 persons entitled to receive the Common Stock upon conversion of the Preferred Stock shall not be deemed to have converted such Preferred Stock until immediately prior to the closing of such sale of securities. If the conversion is in connection with Automatic Conversion provisions of subsection 4(b)(ii) above, such conversion shall be deemed to have been made immediately prior to the close of business on the conversion date described in the stockholder consent approving such conversion, and the persons entitled to receive shares of Common Stock issuable upon such conversion shall be treated for all purposes as the record holders of such shares of Common Stock as of such date.

(d) Conversion Price Adjustments of Preferred Stock for Certain Dilutive Issuances, Splits and Combinations. The Conversion Price of the Preferred Stock shall be subject to adjustment from time to time as follows:

(i) (A) If this corporation shall issue, on or after the date on which the first share of Series C Preferred is issued (the “Series C Original Issue Date”), any Additional Stock (as defined below) without consideration or for a consideration per share less than the Conversion Price applicable to a series of Preferred Stock in effect immediately prior to the issuance of such Additional Stock, the Conversion Price for such series in effect immediately prior to each such issuance shall forthwith (except as otherwise provided in this clause (i)) be adjusted to a price (calculated to the nearest one-thousandth of a cent) determined by multiplying such Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock Outstanding (as defined below) immediately prior to such issuance plus the number of shares of Common Stock that the aggregate consideration received by this corporation for such issuance would purchase at such Conversion Price; and the denominator of which shall be the number of shares of Common Stock Outstanding (as defined below) immediately prior to such issuance plus the number of shares of such Additional Stock. For purposes of this Section 4(d)(i)(A), the term “Common Stock Outstanding” shall mean and include the following: (1) outstanding Common Stock, (2) Common Stock issuable upon conversion of outstanding Preferred Stock, (3) Common Stock issuable upon exercise of outstanding stock options and (4) Common Stock issuable upon exercise (and, in the case of warrants to purchase Preferred Stock, conversion) of outstanding warrants. Shares described in (1) through (4) above shall be included whether vested or unvested, whether contingent or non-contingent and whether exercisable or not yet exercisable. In the event that this corporation issues or sells, or is deemed to have issued or sold, shares of Additional Stock that results in an adjustment to a Conversion Price pursuant to the provisions of this Section 4(d) (the “First Dilutive Issuance”), and this corporation then issues or sells, or is deemed to have issued or sold, shares of Additional Stock in one or more subsequent issuances other than the First Dilutive Issuance that would result in further adjustment to a Conversion Price (each, a “Subsequent Dilutive Issuance”) pursuant to the same instruments as the First Dilutive Issuance, then and in each such case upon a Subsequent Dilutive Issuance the applicable Conversion Price for each series of Preferred Stock shall be reduced to the applicable Conversion Price that would have been in effect had the First Dilutive Issuance and each Subsequent Dilutive Issuance all occurred on the closing date of the First Dilutive Issuance.

(B) No adjustment of the Conversion Price for the Preferred Stock shall be made in an amount less than one-tenth of one cent per share. Except to the limited extent provided for in subsections (E)(3) and (E)(4), no adjustment of such Conversion Price pursuant to this subsection 4(d)(i) shall have the effect of increasing the Conversion Price above the Conversion Price in effect immediately prior to such adjustment.

(C) In the case of the issuance of Additional Stock for cash, the consideration shall be deemed to be the amount of cash paid therefor before deducting any reasonable discounts, commissions or other expenses allowed, paid or incurred by this corporation for any underwriting or otherwise in connection with the issuance and sale thereof.

(D) In the case of the issuance of the Additional Stock for a consideration in whole or in part other than cash, the consideration other than cash shall be deemed to be the fair market value thereof as determined in good faith by the Board of Directors irrespective of any accounting treatment.

(E) In the case of the issuance of options to purchase or rights to subscribe for Common Stock, securities by their terms convertible into or exchangeable for Common Stock or options to purchase or rights to subscribe for such convertible or exchangeable securities, the following provisions shall apply for purposes of determining the number of shares of Additional Stock issued and the consideration paid therefor:

(1) The aggregate maximum number of shares of Common Stock deliverable upon exercise (assuming the satisfaction of any conditions to exercisability, including without limitation, the passage of time, but without taking into account potential antidilution adjustments) of such options to purchase or rights to subscribe for Common Stock shall be deemed to have been issued at the time such options or rights were issued and for a consideration equal to the consideration (determined in the manner provided in subsections 4(d)(i)(C) and (d)(i)(D)), if any, received by this corporation upon the issuance of such options or rights plus the minimum exercise price provided in such options or rights (without taking into account potential antidilution adjustments) for the Common Stock covered thereby.

(2) The aggregate maximum number of shares of Common Stock deliverable upon conversion of, or in exchange (assuming the satisfaction of any conditions to convertibility or exchangeability, including, without limitation, the passage of time, but without taking into account potential antidilution adjustments) for, any such convertible or exchangeable securities or upon the exercise of options to purchase or rights to subscribe for such convertible or exchangeable securities and subsequent conversion or exchange thereof shall be deemed to have been issued at the time such securities were issued or such options or rights were issued and for a consideration equal to the consideration, if any, received by this corporation for any such securities and related options or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the minimum additional consideration, if any, to be received by this corporation (without taking into account potential antidilution adjustments) upon the conversion or exchange of such securities or the exercise of any related options or rights (the consideration in each case to be determined in the manner provided in subsections 4(d)(i)(C) and (d)(i)(D)). If the number of shares of Common Stock issuable upon the exercise, conversion and/or exchange of any convertible or exchangeable securities, or the consideration payable to the

corporation upon such exercise, conversion and/or exchange, cannot be calculated at all at the time such convertible or exchangeable securities is issued or amended, any adjustment to the Conversion Price of a series of Preferred Stock that would result under the terms of this Section 4(d)(i)(E) at the time of such issuance or amendment shall instead be effected at the time such number of shares and/or amount of consideration is first calculable (even if subject to subsequent adjustments), assuming for purposes of calculating such adjustment to the Conversion Price for such series of Preferred Stock that such issuance or amendment took place at the time such calculation can first be made. In the event any convertible or exchangeable securities contains alternative conversion terms, such as a cap on the valuation of the corporation at which such conversion will be effected, or circumstances where the convertible or exchangeable securities may be repaid in lieu of conversion, then the number of shares of Common Stock issuable upon the exercise, conversion and/or exchange of such convertible or exchangeable securities shall be deemed not calculable until such time as the applicable conversion terms are determined.

(3) In the event of any change in the number of shares of Common Stock deliverable or in the consideration payable to this corporation upon exercise of such options or rights or upon conversion of or in exchange for such convertible or exchangeable securities, the Conversion Price of the Preferred Stock, to the extent in any way affected by or computed using such options, rights or securities, shall be recomputed to reflect such change, but no further adjustment shall be made for the actual issuance of Common Stock or any payment of such consideration upon the exercise of any such options or rights or the conversion or exchange of such securities.

(4) Upon the expiration of any such options or rights, the termination of any such rights to convert or exchange or the expiration of any options or rights related to such convertible or exchangeable securities, the Conversion Price of the Preferred Stock, to the extent in any way affected by or computed using such options, rights or securities or options or rights related to such securities, shall be recomputed to reflect the issuance of only the number of shares of Common Stock (and convertible or exchangeable securities that remain in effect) actually issued upon the exercise of such options or rights, upon the conversion or exchange of such securities or upon the exercise of the options or rights related to such securities.

(5) The number of shares of Additional Stock deemed issued and the consideration deemed paid therefor pursuant to subsections 4(d)(i)(E)(1) and (2) shall be appropriately adjusted to reflect any change, termination or expiration of the type described in either subsection 4(d)(i)(E)(3) or (4).

(ii) “Additional Stock” shall mean any shares of Common Stock issued (or deemed to have been issued pursuant to subsection 4(d)(i)(E)) by this corporation on or after the Series C Original Issue Date other than (“Excluded Securities”):

(A) Common Stock issued pursuant to a transaction described in subsection 4(d)(iii) hereof;

(B) Common Stock issued to employees, directors, consultants and other service providers for the primary purpose of soliciting or retaining their services pursuant to plans or agreements approved by the Board of Directors;

(D) Common Stock issued pursuant to the conversion or exercise of convertible or exercisable securities outstanding on the Series C Original Issue Date, in each case provided such issuance is pursuant to the terms of such convertible or exercisable security;

(E) Common Stock issued as acquisition consideration in connection with a bona fide business acquisition by this corporation, whether by merger, consolidation, sale of assets, sale or exchange of stock or otherwise provided that such issuances are approved by Requisite Preferred Director Vote;

(F) Common Stock issued or deemed issued pursuant to subsection 4(d)(i)(E) as a result of a decrease in the Conversion Price of any series of Preferred Stock resulting from the operation of Section 4(d);

(G) Common Stock issued upon conversion of Preferred Stock;

(H) Shares issued pursuant to the Series C Preferred Stock Purchase Agreement, by and among this corporation and certain investors dated as of the date the first shares of Series C Preferred Stock are issued by this corporation (as amended from time to time, the “Purchase Agreement”);

(I) Common Stock issued pursuant to any equipment leasing arrangement or debt financing arrangement, which arrangement is approved by Requisite Preferred Director Vote; or

(J) Common Stock issued to suppliers or third party service providers in connection with the provision of goods or services or issued in connection with sponsored research, collaboration, technology license, development, OEM, marketing or other similar agreements or strategic partnerships, provided such transactions and such issuances are approved by Requisite Preferred Director Vote.

(iii) In the event this corporation should at any time or from time to time after the Series C Original Issue Date fix a record date for the effectuation of a split or subdivision of the outstanding shares of Common Stock or the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in additional shares of Common Stock or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly, additional shares of Common Stock (hereinafter referred to as “Common Stock Equivalents”) without payment of any consideration by such holder for the additional shares of Common Stock or the Common Stock Equivalents (including the additional shares of Common Stock issuable upon conversion or exercise thereof), then, as of such record

date (or the date of such dividend distribution, split or subdivision if no record date is fixed), the Conversion Price of the Preferred Stock shall be appropriately decreased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be increased in proportion to such increase of the aggregate of shares of Common Stock outstanding and those issuable with respect to such Common Stock Equivalents with the number of shares issuable with respect to Common Stock Equivalents determined from time to time in the manner provided for deemed issuances in subsection 4(d)(i)(E).

(iv) If the number of shares of Common Stock outstanding at any time after the Series C Original Issue Date is decreased by a combination of the outstanding shares of Common Stock, then, following the record date of such combination, the Conversion Price for the Preferred Stock shall be appropriately increased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be decreased in proportion to such decrease in outstanding shares.

(e) Other Distributions. In the event this corporation shall declare a distribution payable in securities of other persons, evidences of indebtedness issued by this corporation or other persons, assets (excluding cash dividends) or options or rights not referred to in subsection 4(d)(iii), then, in each such case for the purpose of this subsection 4(e), the holders of the Preferred Stock shall be entitled to a proportionate share of any such distribution as though they were the holders of the number of shares of Common Stock of this corporation into which their shares of Preferred Stock are convertible as of the record date fixed for the determination of the holders of Common Stock of this corporation entitled to receive such distribution.

(f) Recapitalizations. If at any time or from time to time there shall be a recapitalization of the Common Stock (other than a subdivision, combination or merger or sale of assets transaction provided for elsewhere in this Section 4 or in Section 2) provision shall be made so that the holders of the Preferred Stock shall thereafter be entitled to receive upon conversion of the Preferred Stock the number of shares of stock or other securities or property of this corporation or otherwise, to which a holder of Common Stock deliverable upon conversion would have been entitled on such recapitalization. In any such case, appropriate adjustment shall be made in the application of the provisions of this Section 4 with respect to the rights of the holders of the Preferred Stock after the recapitalization to the end that the provisions of this Section 4 (including adjustment of the Conversion Price then in effect and the number of shares purchasable upon conversion of the Preferred Stock) shall be applicable after that event as nearly equivalently as may be practicable.

(g) No Fractional Shares and Certificate as to Adjustments.

(i) No fractional shares shall be issued upon the conversion of any share or shares of the Preferred Stock and the aggregate number of shares of Common Stock to be issued to particular stockholders, shall be rounded down to the nearest whole share and this corporation shall pay in cash the fair market value of any fractional shares as of the time when entitlement to receive such fractional shares is determined. Whether or not fractional shares would be issuable upon such conversion shall be determined on the basis of the total number of shares of Preferred Stock the holder is at the time converting into Common Stock and the number of shares of Common Stock issuable upon such conversion.

(ii) Upon the occurrence of each adjustment or readjustment of the Conversion Price of Preferred Stock pursuant to this Section 4, this corporation, at its expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to each holder of Preferred Stock a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. This corporation shall, upon the written request at any time of any holder of Preferred Stock, furnish or cause to be furnished to such holder a like certificate setting forth (A) such adjustment and readjustment, (B) the Conversion Price for such series of Preferred Stock at the time in effect, and (C) the number of shares of Common Stock and the amount, if any, of other property that at the time would be received upon the conversion of a share of Preferred Stock.

(h) Notices of Record Date. In the event of any taking by this corporation 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 (other than a cash dividend) or other distribution, this corporation shall mail to each holder of Preferred Stock, at least ten (10) days prior to the date specified therein, a notice specifying the date on which any such record is to be taken for the purpose of such dividend or distribution, and the amount and character of such dividend or distribution; provided, however, that subject to compliance with the General Corporation Law such notice period may be shortened upon the written consent of the Requisite Holders.

(i) Reservation of Stock Issuable Upon Conversion. This corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the shares of the Preferred Stock, such number of its shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of the Preferred Stock; and if at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the conversion of all then outstanding shares of the Preferred Stock, in addition to such other remedies as shall be available to the holder of such Preferred Stock, this 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 purposes, including, without limitation, engaging in best efforts to obtain the requisite stockholder approval of any necessary amendment to this Restated Certificate of Incorporation.

(j) Waiver of Adjustment to Conversion Price. Notwithstanding anything herein to the contrary, any downward adjustment of the Conversion Price of any series of Preferred Stock may be waived, either prospectively or retroactively and either generally or in a particular instance, by the consent or vote of the holders of (i) solely with respect to the Conversion Price of the Series A Preferred Stock, a majority of the then outstanding shares of Series A Preferred Stock (voting together as a single class and on an as-converted basis); (ii) solely with respect to the Conversion Price of the Series B Preferred Stock a majority of the then outstanding shares of Series B Preferred Stock (voting together as a single class and on an as-converted basis); and (iii) solely with respect to the Conversion Price of the Series C Preferred Stock at least 60% of the then outstanding shares of Series C Preferred Stock (voting together as a single class and on an as-converted basis). Any such waiver shall bind all future holders of shares of such series of Preferred Stock.

4A. Special Mandatory Conversion.

4A.1. Trigger Event. In the event that any holder of shares of Series C Preferred Stock is a Defaulting Investor (as defined in the Purchase Agreement), then each Subject Share (as defined in the Purchase Agreement) held by such Defaulting Investor and its Affiliates shall automatically, and without further action on the part of such Defaulting Investor and its Affiliates, be converted into such number of fully paid and non-assessable shares of Common Stock as is determined by dividing the applicable Original Issue Price of such Subject Share by a price equal to ten times (10X) the applicable Conversion Price of such Subject Share in effect at the time of conversion, effective upon, subject to, and concurrently with, the consummation of the Second Tranche Closing. Such conversion is referred to as a “Special Mandatory Conversion.” For purposes of this Section 4A, “Affiliate” shall mean, with respect to any Investor (as defined in the Purchase Agreement), any person, entity or firm which, from time to time, directly or indirectly, controls, is controlled by, or is under common control with such Investor, including, without limitation, any general partner, managing member, officer, director or trustee of such Investor, or any venture capital fund or registered investment company now or hereafter existing that is controlled by one or more general partners, managing members or investment advisers of, or shares the same management company or investment adviser with, such Investor. Notwithstanding anything to the contrary, the optional conversion rights of the Series B Preferred Stock and Series C Preferred Stock set forth in Section 4(a) shall not be effective for any of the Investors or their Affiliates until the earliest of (i) the day immediately following the Second Tranche Closing Date, (ii) a Liquidation Event, (iii) the date the obligation to purchase the Second Tranche Shares (as defined in the Purchase Agreement) terminates in accordance with the terms of the Purchase Agreement, or (iv) such other time as specified by this corporation and the Requisite Investors (as defined in the Purchase Agreement) (such earlier date, the “Expiration Date”).

4A.2. Procedural Requirements. Upon a Special Mandatory Conversion, each Defaulting Investor and its Affiliates that hold Subject Shares to be converted pursuant to Section 4A.1 shall be sent written notice of such Special Mandatory Conversion and the place designated for mandatory conversion of all such Subject Shares pursuant to this Section 4A.2. Upon receipt of such notice, each Defaulting Investor and its Affiliates that hold such Subject Shares in certificated form shall surrender his, her or its certificate or certificates for all such shares (or, if such holder alleges that any such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to this corporation to indemnify this corporation against any claim that may be made against this corporation on account of the alleged loss, theft or destruction of such certificate) to this corporation at the place designated in such notice. If so required by this corporation, any certificates surrendered for conversion shall be endorsed or accompanied by written instrument or instruments of transfer, in form satisfactory to this corporation, duly executed by the registered holder or by his, her or its attorney duly authorized in writing. All rights with respect to the Subject Shares converted pursuant to Section 4A.1, including the rights, if any, to receive notices and vote (other than as a holder of Common Stock), will terminate at the time of the Special Mandatory Conversion (notwithstanding the failure of the holder or holders thereof to surrender any certificates for such shares at or prior to such time), except only the rights of the holders thereof, upon surrender of any certificate or certificates of such holders therefor (or lost certificate affidavit and agreement), to receive the items provided for in the next sentence of this Section 4A.2. As soon as practicable after the Special Mandatory Conversion and, if applicable, the surrender of any certificate or certificates (or lost certificate affidavit and agreement) for Subject Shares so converted, this corporation shall (a) issue and deliver to such holder, or to his, her or its nominees, a certificate or certificates for the number of full shares of Common Stock issuable on such conversion in accordance with the provisions hereof and (b) pay cash as provided in Section 4(g) in lieu of any fraction of a share of Common Stock otherwise issuable upon such conversion and the payment of any declared but unpaid dividends on the Subject Shares converted.

Such converted Subject Shares shall be retired and cancelled and may not be reissued as shares of such series, and this corporation may thereafter take such appropriate action (without the need for stockholder action) as may be necessary to reduce the authorized number of shares of Series B Preferred Stock and Series C Preferred Stock accordingly.

5. Voting Rights.

(a) General Voting Rights. The holder of each share of Preferred Stock shall have the right to one vote for each share of Common Stock into which such Preferred Stock could then be converted, and with respect to such vote, such holder shall have full voting rights and powers equal to the voting rights and powers of the holders of Common Stock, and shall be entitled, notwithstanding any provision hereof, to notice of any stockholders’ meeting in accordance with the Bylaws of this corporation, and except as provided by law or in subsection 5(b) below with respect to the election of directors by the separate class vote of the holders of Common Stock, shall be entitled to vote, together with holders of Common Stock, with respect to any question upon which holders of Common Stock have the right to vote. Fractional votes shall not, however, be permitted and any fractional voting rights available on an as-converted basis (after aggregating all shares into which shares of Preferred Stock held by each holder could be converted) shall be rounded to the nearest whole number (with one-half (1/2) being rounded upward).

(b) Voting for the Election of Directors. The holders of such shares of Series B Preferred Stock, exclusively and as a separate class, shall be entitled to elect two (2) directors of this corporation (the “Series B Directors”) at any election of directors and the holders of such shares of Series C Preferred Stock, exclusively and as a separate class, shall be entitled to elect one director of this corporation (the “Series C Director”, together with the Series B Directors, the “Preferred Directors”) at any election of directors. Any remaining directors of this corporation shall be elected by the holders of a majority of the then outstanding stock of the corporation (voting together as a single class and not as separate series, and on an as-converted basis) (the “Joint Directors”).

Notwithstanding the provisions of Section 223(a)(1) and 223(a)(2) of the General Corporation Law, any vacancy, including newly created directorships resulting from any increase in the authorized number of directors or amendment of this Restated Certificate of Incorporation, and vacancies created by removal or resignation of a director, may be filled by a majority of the directors then in office, though less than a quorum, or by a sole remaining director, and the directors so chosen shall hold office until the next annual election and until their successors are duly elected and qualified, unless sooner displaced; provided, however, that where such vacancy occurs among the directors elected by the holders of a class or series of stock, the holders of shares of such class or series may override the Board of Directors’ action to fill such vacancy by (i) voting for their own designee to fill such vacancy at a meeting of this corporation’s stockholders or (ii) written consent, if the consenting stockholders hold a sufficient number of shares to elect their designee at a meeting of the stockholders.

Any director may be removed during his or her term of office, either with or without cause, by, and only by, the affirmative vote of the holders of the shares of the class or series of stock entitled to elect such director or directors, given either at a special meeting of such stockholders duly called for that purpose or pursuant to a written consent of stockholders, and any vacancy thereby created may be filled by the holders of that class or series of stock represented at the meeting or pursuant to written consent.

6. Protective Provisions.

(a) Preferred Stock Protective Provisions. So long as 25% of the shares of Preferred Stock originally issued (as adjusted for any stock splits, stock dividends, combinations, subdivisions, recapitalizations or the like with respect to such Preferred Stock) remains outstanding, this corporation shall not, either directly or indirectly by amendment, merger, domestication, transfer, continuance, reorganization, recapitalization, reclassification, waiver, statutory conversion, consolidation or otherwise) effect any of the following acts or transactions without (in addition to any other vote required by law or this Restated Certificate of Incorporation) first obtaining the approval by vote or written consent, as provided by law, of the Requisite Holders (and any such act or transaction that has not been approved by such consent or vote prior to such act or transaction being effected shall be null and void ab initio, and of no force or effect):

(i) consummate a Liquidation Event;

(v) unless approved by Requisite Preferred Director Vote, incur any indebtedness for borrowed money, including but not limited to obligations and contingent obligations under guarantees, or permit any subsidiary to take any such action with respect to any debt security lien, security interest or other indebtedness for borrowed money, if the aggregate indebtedness of this corporation and its subsidiaries would exceed one million dollars ($1,000,000.00) (other than equipment leases, bank lines of credit, letters of credit or trade payables, in each case, incurred in the ordinary course), or create any lien or security interest (except for purchase money liens or statutory liens of landlords, mechanics, materialmen, workmen, warehousemen and other similar persons arising or incurred in the ordinary course of business);

(vi) create or hold capital stock in, any subsidiary that is not wholly owned (either directly or through one or more other subsidiaries) by this corporation, or permit any subsidiary to create, or authorize the creation of, or issue or obligate itself to issue, any shares of any class or series of capital stock, or sell, transfer or otherwise dispose of any capital stock of any direct or indirect subsidiary of this corporation, or permit any direct or indirect subsidiary to sell, lease, transfer, exclusively license or otherwise dispose (in a single transaction or series of related transactions) of all or substantially all of the assets of such subsidiary;

(vii) authorize, create or issue any equity security (including, without limitation, (A) any other security convertible into or exercisable for any such equity security or (B) any unit of debt and equity securities) having a preference over, or being on a parity with, any series of Preferred Stock with respect to dividends, liquidation or redemption, other than the issuance of any authorized but unissued shares of Preferred Stock designated in this Restated Certificate of Incorporation (including, without limitation, any security convertible into or exercisable for such shares of Preferred Stock);

(viii) (A) reclassify, alter or amend any existing security of this corporation that is pari passu with the Preferred Stock with respect to dividends, liquidation or redemption, if such reclassification, alteration or amendment would render such other security senior to the Preferred Stock in respect of any such right, preference or privilege or (B) reclassify, alter or amend any existing security of this corporation that is junior to the Preferred Stock with respect to dividends, liquidation or redemption, if such reclassification, alteration or amendment would render such other security senior to or pari passu with the Preferred Stock in respect of any such right, preference or privilege;

(ix) other than a redemption pursuant to Section 2(e), redeem, purchase or otherwise acquire (or pay into or set aside for a sinking fund for such purpose) any share or shares of Preferred Stock or Common Stock; provided, however, that this restriction shall not apply to the repurchase of shares of Common Stock from employees, officers, directors, consultants or other persons performing services for this corporation or any subsidiary pursuant to agreements approved by the Board of Directors under which this corporation has the option to repurchase such shares at the original per share purchase price (as adjusted for any stock splits, stock dividends, combinations, subdivisions, recapitalizations or the like) upon the occurrence of certain events, such as the termination of employment or service, or pursuant to a right of first refusal;

(x) redomicile this corporation to a jurisdiction other than the State of Delaware;

(xi) change the authorized number of, or method of electing the, directors of this corporation, or change the number of votes entitled to be cast by any director(s) on any matter; or

(xii) pay or declare any dividend or other distribution on any shares of capital stock of this corporation.

(b) Series C Preferred Stock Protective Provision. So long as 25% of the shares of Series C Preferred Stock originally issued (as adjusted for any stock splits, stock dividends, combinations, subdivisions, recapitalizations or the like with respect to such Preferred Stock) remains outstanding, this corporation shall not, either directly or indirectly by amendment, merger, domestication, transfer, continuance, reorganization, recapitalization, reclassification, waiver, statutory conversion, consolidation or otherwise) increase or decrease (other than by redemption or conversion) the total number of authorized shares of Series C Preferred Stock without (in addition to any other vote required by law or this Restated Certificate of Incorporation) obtaining the approval by vote or written consent, as provided by law, of the holders of sixty percent (60%) of the shares of the Series C Preferred Stock then outstanding (voting together as a single class and on an as-converted basis), and the taking of such act without the prior consent or vote being effected shall be null and void ab initio, and of no force or effect.

7. Status of Converted Stock. In the event any shares of Preferred Stock shall be converted pursuant to Section 4 hereof, the shares so converted shall be cancelled and shall not be issuable by this corporation. The Restated Certificate of Incorporation of this corporation shall be appropriately amended to effect the corresponding reduction in this corporation’s authorized capital stock.

8. Notices. Any notice required by the provisions of this Article IV(B) to be given to the holders of shares of Preferred Stock shall be deemed given (a) five (5) days following its deposit in the United States mail, postage prepaid, and addressed to each holder of record at his, her or its address appearing on the books of this corporation, (b) upon such notice being provided by electronic transmission in a manner permitted by the General Corporation Law or (c) five (5) days following such notice being provided in another manner then permitted by the General Corporation Law.

9. Waiver. Except as otherwise set forth herein, (a) subject to clause (b) below, any of the rights, powers, preferences and other terms of the Preferred Stock set forth herein may be waived on behalf of all holders of Preferred Stock by the affirmative written consent or vote of the holders that would otherwise be required to amend such right, powers, preferences, and other terms and (b) at any time more than one series of Preferred Stock is issued and outstanding, any of the rights, powers, preferences and other terms of any series of Preferred Stock set forth herein may be waived on behalf of all holders of such series of Preferred Stock only by the affirmative written consent or vote of the holders of such series that would otherwise be required to amend such right, power, preference, or other term.

C. Common Stock. The rights, preferences, privileges and restrictions granted to and imposed on the Common Stock are as set forth below in this Article IV(C).

1. Dividend Rights. Subject to the prior rights of holders of all classes of stock at the time outstanding having prior rights as to dividends, the holders of the Common Stock shall be entitled to receive, when, as and if declared by the Board of Directors, out of any assets of this corporation legally available therefor, any dividends as may be declared from time to time by the Board of Directors.

2. Liquidation Rights. Upon the liquidation, dissolution or winding up of this corporation, the assets of this corporation shall be distributed as provided in Section 2 of Article IV(B) hereof.

3. Redemption. The Common Stock is not redeemable at the option of the holder.

4. Voting Rights. The holder of each share of Common Stock shall have the right to one vote for each such share, and shall be entitled to notice of any stockholders’ meeting in accordance with the Bylaws of this corporation, and shall be entitled to vote upon such matters and in such manner as may be provided by law. The number of authorized shares of Common Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the stock of this corporation entitled to vote, irrespective of the provisions of Section 242(b)(2) of the General Corporation Law.

ARTICLE V

Except as otherwise provided in this Restated Certificate of Incorporation, in furtherance and not in limitation of the powers conferred by statute, the Board of Directors is expressly authorized to make, repeal, alter, amend and rescind any or all of the Bylaws of this corporation.

ARTICLE VI

Subject to the requirements of Section 6 of Article IV(B) hereof, the number of directors of this corporation shall be determined in the manner set forth in the Bylaws of this corporation. Unless otherwise provided herein, each director shall be entitled to one vote on each matter presented to the Board of Directors; provided that to the extent the approval of any particular director or directors is required by any agreement for specified actions, receipt of such approval shall be necessary for the Board of Directors to authorize such actions; provided further that, so long as the holders of Preferred Stock are entitled to elect a Preferred Director, the Requisite Preferred Director Vote shall be required for the authorization by the Board of Directors of any of the matters set forth in Section 3.12 of the Amended and Restated Investors’ Rights Agreement, dated as of or around the Series C Original Issue Date, by and among the corporation and the other parties thereto, as such agreement may be amended from time to time, to the extent required by such agreement and if any Preferred Director is then serving.

ARTICLE VII

Elections of directors need not be by written ballot unless the Bylaws of this corporation shall so provide.

ARTICLE VIII

Meetings of stockholders may be held within or without the State of Delaware, as the Bylaws of this corporation may provide. The books of this corporation may be kept (subject to any provision contained in the statutes) outside the State of Delaware at such place or places as may be designated from time to time by the Board of Directors or in the Bylaws of this corporation.

ARTICLE IX

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

Any amendment, repeal or modification of the foregoing provisions of this Article IX by the stockholders of this corporation shall not adversely affect any right or protection of a director of this corporation existing at the time of, or increase the liability of any director of this corporation with respect to any acts or omissions of such director occurring prior to, such amendment, repeal or modification.

ARTICLE X

This corporation reserves the right to amend, alter, change or repeal any provision contained in this Restated Certificate of Incorporation, in the manner now or hereafter prescribed by statute, and, subject to the requirements of the General Corporation Law and Section 6 of Article IV(B) hereof, all rights conferred upon stockholders herein are granted subject to this reservation.

ARTICLE XI

To the fullest extent permitted by applicable law, this corporation is authorized to provide indemnification of (and advancement of expenses to) directors, officers, employees and agents of this corporation (and any other persons to which General Corporation Law permits this corporation to provide indemnification) through Bylaw provisions, agreements with such persons, vote of stockholders or disinterested directors or otherwise, in excess of the indemnification and advancement otherwise permitted by Section 145 of the General Corporation Law.

Any amendment, repeal or modification of the foregoing provisions of this Article XI shall not adversely affect any right or protection of a director, officer, employee, agent or other person existing at the time of, or increase the liability of any such person with respect to any acts or omissions of such person occurring prior to, such amendment, repeal or modification.

ARTICLE XII

This corporation renounces any interest or expectancy of this corporation in, or in being offered an opportunity to participate in, any Excluded Opportunity. An “Excluded Opportunity” is any matter, transaction or interest that is presented to, or acquired, created or developed by, or which otherwise comes into the possession of, (i) any director of this corporation who is not an employee of this corporation or any of its subsidiaries, or (ii) any holder of Preferred Stock or any partner, member, director, stockholder, employee, affiliate or agent of any such holder, other than someone who is an employee of this corporation or any of its subsidiaries (collectively, “Covered Persons”), unless such matter, transaction or interest is presented to, or acquired, created or developed by, or otherwise comes into the possession of, a Covered Person expressly and solely in such Covered Person’s capacity as a director of this corporation while such

Covered Person is performing services in such capacity. Any repeal or modification of this Article XII will only be prospective and will not affect the rights under this Article XII in effect at the time of the occurrence of any actions or omissions to act giving rise to liability. Notwithstanding anything to the contrary contained elsewhere in this Restated Certificate of Incorporation, in addition to any other vote required by law or this Restated Certificate of Incorporation, the affirmative vote of the Requisite Holders will be required to amend or repeal, or to adopt any provisions inconsistent with this Article XII.

A. Forum Selection. Unless this corporation consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware) shall, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of this corporation, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of this corporation to this corporation or this corporation’s stockholders, (iii) any action arising pursuant to any provision of the General Corporation Law or this Restated Certificate of Incorporation or the Bylaws (as either may be amended from time to time), or (iv) any action asserting a claim governed by the internal affairs doctrine, except for, as to each of (i) through (iv) above, any claim as to which the Court of Chancery determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten (10) days following such determination), which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery, or for which the Court of Chancery does not have subject matter jurisdiction. Any person or entity purchasing or otherwise acquiring or holding any interest in shares of capital stock of this corporation shall be deemed to have notice of and consented to the provisions of this Article XIII.

B. Personal Jurisdiction. If any action the subject matter of which is within the scope of Article XIII(A) is filed in a court other than a court located within the State of Delaware (a “Foreign Action”) in the name of any stockholder, such stockholder shall be deemed to have consented to (i) the personal jurisdiction of the state and federal courts located within the State of Delaware in connection with any action brought in any such court to enforce Article XIII(A) (an “FSC Enforcement Action”) and (ii) having service of process made upon such stockholder in any such FSC Enforcement Action by service upon such stockholder’s counsel in the Foreign Action as agent for such stockholder.

ARTICLE XIV

If any provision or provisions of this Restated Certificate of Incorporation shall be held to be invalid, illegal or unenforceable as applied to any person or entity or circumstance for any reason whatsoever, then, to the fullest extent permitted by law, the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Restated Certificate of Incorporation (including, without limitation, each portion of any sentence of this Restated Certificate of Incorporation containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) and the application of such provision to other persons or entities and circumstances shall not in any way be affected or impaired thereby.
