3.    Liquidation Rights.

(a)    Liquidation Preference.

(i)    In the event of any liquidation, dissolution or winding up of the Corporation, either voluntary or involuntary, the holders of the Series E Preferred Stock shall be entitled to receive prior and in preference to any Distribution of any of the assets of the Corporation to the holders of the Series D Preferred Stock, Series C Preferred Stock, Series C-1 Preferred Stock, Series B-1 Preferred Stock, Series B Preferred Stock, Series A Preferred Stock or Common Stock by reason of their ownership of such stock, an amount per share for each share of Series E Preferred Stock held by them equal to the greater of (i) the sum of (1) the Original Issue Price specified for such share of Series E Preferred Stock, and (2) all declared but unpaid dividends (if any) on such share of Series E Preferred Stock, and (ii) such amount per share as would have been payable per such share of, Series E Preferred Stock had all shares of Series E Preferred Stock been converted into Common Stock pursuant to Section 4 immediately prior to such liquidation, dissolution or winding up of the Corporation. If upon the liquidation, dissolution or winding up of the Corporation, the assets of the Corporation legally available for distribution to the holders of the Series E Preferred Stock are insufficient to permit the payment to such holders of the full amounts specified in this Section 3(a)(i), then the entire assets of the Corporation legally available for distribution shall be distributed with equal priority and pro rata among the holders of the Series E Preferred Stock in proportion to the full amounts they would otherwise be entitled to receive pursuant to this Section 3(a)(i).

(ii)    In the event of any liquidation, dissolution or winding up of the Corporation, either voluntary or involuntary, and after payment of the amounts due to the holders of the Series E Preferred Stock pursuant to Section 3(a)(i), the holders of the Series D Preferred Stock, Series C Preferred Stock and Series C-1 Preferred Stock shall be entitled to receive, with equal priority among the holders of the Series D Preferred Stock, Series C Preferred Stock and Series C-1 Preferred Stock and prior and in preference to any Distribution of any of the assets of the Corporation to the holders of the Series B-1 Preferred Stock, Series B Preferred Stock, Series A Preferred Stock or Common Stock by reason of their ownership of such stock, an amount per share for each share of Series D Preferred Stock, Series C Preferred Stock and Series C-1 Preferred Stock held by them equal to the greater of (i) the sum of (1) the Original Issue Price specified for such share of Series D Preferred Stock, Series C Preferred Stock or Series C-1 Preferred Stock, as applicable, and (2) all declared but unpaid dividends (if any) on such share of Series D Preferred Stock, Series C Preferred Stock or Series C-1 Preferred Stock, as applicable, and (ii) such amount per share as would have been payable per such share of, Series D Preferred Stock, Series C Preferred Stock or Series C-1 Preferred Stock, as applicable, had all shares of Series D Preferred Stock, Series C Preferred Stock or Series C-1 Preferred Stock, as applicable, been converted into Common Stock pursuant to Section 4 immediately prior to such liquidation, dissolution or winding up of the Corporation. If upon the liquidation, dissolution or winding up of the Corporation, the assets of the Corporation legally available for distribution to the holders of the Series D Preferred Stock, Series C

5

Preferred Stock and Series C-1 Preferred Stock are insufficient to permit the payment to such holders of the full amounts specified in this Section 3(a)(ii), then the entire assets of the Corporation legally available for distribution shall be distributed with equal priority and pro rata among the holders of the, Series D Preferred Stock, Series C Preferred Stock and Series C-1 Preferred Stock in proportion to the full amounts they would otherwise be entitled to receive pursuant to this Section 3(a)(ii).

(iii)    In the event of any liquidation, dissolution or winding up of the Corporation, either voluntary or involuntary, and after payment of the amounts due to the holders of the Series E Preferred Stock pursuant to Section 3(a)(i) and the Series D Preferred Stock, Series C Preferred Stock and Series C-1 Preferred Stock pursuant to Section 3(a)(ii), the holders of the Series B-1 Preferred Stock shall be entitled to receive, prior and in preference to any Distribution of any of the assets of the Corporation to the holders of the Series B Preferred Stock, Series A Preferred Stock or Common Stock by reason of their ownership of such stock, an amount per share for each share of Series B-1 Preferred Stock held by them equal to the greater of (i) the sum of (1) the Original Issue Price specified for such share of Series B-1 Preferred Stock and (2) all declared but unpaid dividends (if any) on such share of Series B-1 Preferred Stock, and (ii) such amount per share as would have been payable had all shares of Series B-1 Preferred Stock been converted into Common Stock pursuant to Section 4 immediately prior to such liquidation, dissolution or winding up of the Corporation. If upon the liquidation, dissolution or winding up of the Corporation, the remaining assets of the Corporation legally available for distribution to the holders of the Series B-1 Preferred Stock are insufficient to permit the payment to such holders of the full amounts specified in this Section 3(a)(iii), then the entire assets of the Corporation legally available for distribution shall be distributed with equal priority and pro rata among the holders of the Series B-1 Preferred Stock in proportion to the full amounts they would otherwise be entitled to receive pursuant to this Section 3(a)(iii).

(iv)    In the event of any liquidation, dissolution or winding up of the Corporation, either voluntary or involuntary, and after payment of the amounts due to the holders of the Series E Preferred Stock pursuant to Section 3(a)(i), the Series D Preferred Stock, Series C Preferred Stock and Series C-1 Preferred stock pursuant to Section 3(a)(ii) and the Series B-1 Preferred Stock pursuant to Section 3(a)(iii), the holders of the Series B Preferred Stock and Series A Preferred Stock shall be entitled to receive, with equal priority among the holders of the Series B Preferred Stock and Series A Preferred Stock and prior and in preference to any Distribution of any of the assets of the Corporation to the holders of the Common Stock by reason of their ownership of such stock, an amount per share for each share of Series B Preferred Stock and Series A Preferred Stock held by them equal to the greater of (i) the sum of (1) the Original Issue Price specified for such share of Series B Preferred Stock or Series A Preferred Stock, as applicable, and (2) all declared but unpaid dividends (if any) on such share of Series B Preferred Stock or Series A Preferred Stock, as applicable, and (ii) such amount per share as would have been payable per share of Series B Preferred Stock or Series A Preferred Stock, as applicable, had all shares of Series B Preferred Stock or Series A Preferred Stock, as applicable, been converted into Common Stock pursuant to Section 4 immediately prior to such liquidation, dissolution or winding up of the Corporation. If upon the liquidation, dissolution or winding up of the Corporation, the remaining assets of the Corporation legally available for distribution to the holders of the Series B Preferred Stock and Series A Preferred Stock are insufficient to permit the payment to such holders of the full amounts specified in this Section 3(a)(iv), then the entire assets of the Corporation legally available for distribution shall be distributed with equal priority and pro rata among the holders of the Series B Preferred Stock and Series A Preferred Stock in proportion to the full amounts they would otherwise be entitled to receive pursuant to this Section 3(a)(iv).

(b)    Remaining Assets. After the payment or setting aside for payment to the holders of Preferred Stock of the full amounts specified in Section 3(a), the entire remaining assets of the Corporation legally available for distribution shall be distributed pro rata to holders of the Common Stock in proportion to the number of shares of Common Stock held by them.

6

(c)    Shares not Treated as Both Preferred Stock and Common Stock in any Distribution. Shares of Preferred Stock shall not be entitled to be converted into shares of Common Stock in order to participate in any Distribution, or series of Distributions, as shares of Common Stock, without first foregoing participation in the Distribution, or series of Distributions, as shares of Preferred Stock.

(d)    Reorganization. For purposes of this Section 3, a liquidation, dissolution or winding up of the Corporation shall be deemed to be occasioned by, or to include, (i) the acquisition of the Corporation by another entity by means of any transaction or series of related transactions to which the Corporation is party (including, without limitation, any stock acquisition, reorganization, merger or consolidation but excluding any sale of stock pursuant to a bona fide equity financing) other than a transaction or series of transactions in which the shares of capital stock of the Corporation outstanding immediately prior to such transaction continue to represent, or are converted into or exchanged for shares of capital stock that represent, immediately after such transaction or series of related transactions, at least a majority of the total voting power with the same rights and in substantially the same relative proportions, of the capital stock of the surviving or resulting entity (or if the Corporation or such other surviving or resulting entity is a wholly-owned subsidiary immediately following such acquisition, its parent); (ii) a sale, lease, exclusive license or other disposition of all or substantially all of the assets or intellectual property rights of the Corporation and its subsidiaries taken as a whole by means of any transaction or series of related transactions, except where such sale, lease, exclusive license or other disposition is to a wholly-owned subsidiary of the Corporation; or (iii) any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary. The treatment of any transaction or series of related transactions as a liquidation, dissolution or winding up pursuant to clause (i) or (ii) of the preceding sentence may be waived by the consent or vote of the Requisite Preferred Holders; provided, however, that with respect to any transaction or series of related transactions in which the assets to be distributed by the Corporation to the holders of the Series A Preferred Stock would be less than the amounts otherwise payable to the holders of the Series A Preferred Stock pursuant to Section 3(a)(iv), the treatment of any such transaction or series of related transactions as a liquidation, dissolution or winding up pursuant to clause (i) or (ii) of the preceding sentence may only be waived with respect to the Series A Preferred Stock, by the consent or vote of the holders of a majority of the outstanding shares of Series A Preferred Stock (voting as a separate class) and including Maveron and, provided, further, that with respect to any transaction or series of related transactions in which the assets to be distributed by the Corporation to the holders of the Series E Preferred Stock would be less than the amounts otherwise payable to the holders of the Series E Preferred Stock pursuant to Section 3(a)(i), the treatment of any such transaction or series of related transactions as a liquidation, dissolution or winding up pursuant to clause (i) or (ii) of the preceding sentence may only be waived with respect to the Series E Preferred Stock, by the consent or vote of the Series E Majority.

(e)    Valuation of Non-Cash Consideration. If any assets of the Corporation distributed to stockholders in connection with any liquidation, dissolution, or winding up of the Corporation are other than cash, then the value of such assets shall be their fair market value as determined in good faith by the Board of Directors (including the consent of a majority of the Preferred Directors), except that any publicly-traded securities to be distributed to stockholders in a liquidation, dissolution, or winding up of the Corporation shall be valued as follows:

(i)    If the securities are then traded on a national securities exchange, then the value of the securities shall be deemed to be the average of the closing prices of the securities on such exchange over the ten (10) trading day period ending five (5) trading days prior to the Distribution;

(ii)    if the securities are actively traded over-the-counter, then the value of the securities shall be deemed to be the average of the closing bid prices of the securities over the ten (10) trading day period ending five (5) trading days prior to the Distribution.

7

In the event of a merger or other acquisition of the Corporation by another entity, the Distribution date shall be deemed to be the date such transaction closes.

(f)    Allocation of Escrow and Contingent Consideration. If, upon any liquidation, dissolution or winding up of the Corporation, any portion of the consideration payable to the stockholders of the Corporation is placed into escrow and/or is payable to the stockholders of the Corporation subject to contingencies, the definitive agreement governing such liquidation, dissolution or winding up of the Corporation will provide that (A) the portion of such consideration that is not placed in escrow and not subject to any contingencies (the “Initial Consideration”) will be allocated among the holders of capital stock of the Corporation in accordance with Section 3(a) and 3(b) as if the Initial Consideration were the only consideration payable in connection with such liquidation, dissolution or winding up of the Corporation and (B) any additional consideration that becomes payable to the stockholders of the Corporation upon release from escrow or satisfaction of contingencies will be allocated among the holders of capital stock of the Corporation in accordance with Sections 3(a) and 3(b) after taking into account the previous payment of the Initial Consideration as part of the same transaction.

4.    Conversion. The holders of the Preferred Stock shall have conversion rights as follows:

(a)    Right to Convert. 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 the Corporation or any transfer agent for the Preferred Stock, into that number of fully-paid, nonassessable shares of Common Stock determined by dividing the Original Issue Price for the relevant series by the Conversion Price for such series. (The number of shares of Common Stock into which each share of Preferred Stock of a series may be converted is hereinafter referred to as the “Conversion Rate” for each such series.) Upon any decrease or increase in the Conversion Price for any series of Preferred Stock, as described in this Section 4, the Conversion Rate for such series shall be appropriately increased or decreased.

(b)    Automatic Conversion.

(i)    Each share of Preferred Stock shall automatically be converted into fully-paid, non-assessable shares of Common Stock at the then effective Conversion Rate for such share (i) immediately prior to the closing of a firm commitment underwritten initial public offering pursuant to an effective registration statement filed under the Securities Act of 1933, as amended (the “Securities Act”), that results in the Corporation’s Common Stock being traded or listed on the New York Stock Exchange or NASDAQ, provided that (i) the aggregate gross proceeds to the Corporation are not less than $75,000,000 (before deduction of underwriters commissions and expenses) and (ii) the price per share for the Corporation’s Common Stock is at least 1.29 times the Original Series E Issue Price, as adjusted for any stock splits, stock dividends, combinations, subdivisions, recapitalizations or the like (a “Qualified IPO”).

(ii)    Each share of the Series A Preferred shall automatically be converted into fully-paid, non-assessable shares of Common Stock at the then effective Conversion Rate for such share, upon the vote of the holders of a majority of the outstanding shares of Series A Preferred Stock (voting as a separate class) and including Maveron.

(iii)    Each share of the Series B Preferred and Series B-1 Preferred shall automatically be converted into fully-paid, non-assessable shares of Common Stock at the then effective Conversion Rate for such share, upon the vote of the holders of a majority of the outstanding shares of Series B Preferred Stock and Series B-1 Preferred Stock (voting together as a single and separate class on an as-converted basis) and including NEA.

(iv)    Each share of the Series C Preferred Stock and Series C-1 Preferred Stock shall

8

automatically be converted into fully-paid, non-assessable shares of Common Stock at the then effective Conversion Rate for such share, upon the vote of the holders of a majority of the outstanding shares of Series C Preferred Stock and Series C-1 Preferred Stock (voting together as a single and separate class on an as-converted basis) and including both (i) NEA and (ii) Pivotal.

(v)    Each share of the Series D Preferred shall automatically be converted into fully-paid, non-assessable shares of Common Stock at the then effective Conversion Rate for such share, upon the vote of the holders of a majority of the outstanding shares of Series D Preferred Stock (voting as a separate class).

(vi)    Each share of the Series E Preferred Stock shall automatically be converted into fully-paid, non-assessable shares of Common Stock at the then effective Conversion Rate for such share, upon the vote of the Series E Majority.

(vii)    Each of the events referred to in subsections (i), (ii), (iii), (iv) and (v) of this Section 4(b) are referred to herein as an “Automatic Conversion Event”.

(c)    Mechanics of Conversion. No fractional shares of Common Stock shall be issued upon conversion of Preferred Stock. In lieu of any fractional shares to which the holder would otherwise be entitled, the Corporation shall pay cash equal to such fraction multiplied by the then fair market value of a share of Common Stock as determined by the Board of Directors. For such purpose, all shares of Preferred Stock held by each holder of Preferred Stock shall be aggregated, and any resulting fractional share of Common Stock shall be paid in cash. Before any holder of Preferred Stock shall be entitled to convert the same into full shares of Common Stock, and to receive certificates therefor, the holder shall either (A) surrender the certificate or certificates therefor, duly endorsed, at the office of the Corporation or of any transfer agent for the Preferred Stock or (B) notify the Corporation or its transfer agent that such certificates have been lost, stolen or destroyed and execute an agreement satisfactory to the Corporation to indemnify the Corporation from any loss incurred by it in connection with such certificates, and shall give written notice to the Corporation at such office that the holder elects to convert the same; provided, however, that on the date of an Automatic Conversion Event, the outstanding shares of Preferred Stock shall be converted automatically without any further action by the holders of such shares and whether or not the certificates representing such shares are surrendered to the Corporation or its transfer agent; provided further, however, that the Corporation shall not be obligated to issue certificates evidencing the shares of Common Stock issuable upon such Automatic Conversion Event unless either the certificates evidencing such shares of Preferred Stock are delivered to the Corporation or its transfer agent as provided above, or the holder notifies the Corporation or its transfer agent that such certificates have been lost, stolen or destroyed and executes an agreement satisfactory to the Corporation to indemnify the Corporation from any loss incurred by it in connection with such certificates. 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. On the date of the occurrence of an Automatic Conversion Event, each holder of record of shares of Preferred Stock shall be deemed to be the holder of record of the Common Stock issuable upon such conversion, notwithstanding that the certificates representing such shares of Preferred Stock shall not have been surrendered at the office of the Corporation, that notice from the Corporation shall not have been received by any holder of record of shares of Preferred Stock, or that the certificates evidencing such shares of Common Stock shall not then be actually delivered to such holder.

No adjustment in the Conversion Price of a particular series of Preferred Stock shall be made in respect of the issuance of Additional Shares of Common unless the consideration per share (as determined pursuant to paragraph 4(d)(v)) for an Additional Share of Common issued or deemed to be issued by the Corporation is less than the Conversion Price of Series E Preferred Stock as in effect on the date of, and immediately prior to, such issue.

(iii)    Deemed Issue of Additional Shares of Common. In the event the Corporation at any time or from time to time after the date of the filing of this Amended and Restated Certificate of Incorporation 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, the conversion or exchange of such Convertible Securities or, in the case of Options for Convertible Securities, the exercise of such Options and the conversion or exchange of the underlying securities, shall be deemed to have been 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 shares are deemed to be issued:

(1)    no further adjustment in the Conversion Price of any series of Preferred Stock shall be made upon the subsequent issue of Convertible Securities or shares of Common Stock in connection with the exercise of such Options or conversion or exchange of such Convertible Securities;

(2)    if such Options or Convertible Securities by their terms provide, with the passage of time or otherwise, for any change in the consideration payable to the Corporation or in the number of shares of Common Stock issuable upon the exercise, conversion or exchange thereof (other than a change pursuant to the anti-dilution provisions of such Options or Convertible Securities such as this Section 4(d) or pursuant to Recapitalization provisions of such Options or Convertible Securities such as Sections 4(e), 4(f) and 4(g) hereof), the Conversion Price of each series of Preferred Stock and any subsequent adjustments based thereon shall be recomputed to reflect such change as if such change had been in effect as of the original issue thereof (or upon the occurrence of the record date with respect thereto);

(3)    no readjustment pursuant to clause (2) above shall have the effect of increasing the Conversion Price of a series of Preferred Stock to an amount above the Conversion Price that would have resulted from any other issuances of Additional Shares of Common and any other adjustments provided for herein between the original adjustment date and such readjustment date;

(4)    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 of each Series of Preferred Stock computed 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 recomputed as if:

(a)    in the case of Convertible Securities or Options for Common Stock, the only Additional Shares of Common 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 such exercised Options 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

11

(b)    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 deemed to have been then issued was the consideration actually received by the Corporation for the issue of such exercised Options, plus the consideration deemed to have been received by the Corporation (determined pursuant to Section 4(d)(v)) upon the issue of the Convertible Securities with respect to which such Options were actually exercised; and

(5)    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 canceled as of the close of business on such record date, and thereafter the Conversion Price shall be adjusted pursuant to this paragraph 4(d)(iii) as of the actual date of their issuance.

(iv)    Adjustment of Conversion Price Upon Issuance of Additional Shares of Common.

(1)    In the event this Corporation shall issue Additional Shares of Common (including Additional Shares of Common deemed to be issued pursuant to paragraph 4(d)(iii)) without consideration or for a consideration per share less than the Conversion Price of the Series E Preferred Stock in effect on the date of and immediately prior to such issue, then, the Conversion Price of such series of Preferred Stock shall be reduced, concurrently with such issue, to a price (calculated to the nearest cent) determined by multiplying such Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of shares which the aggregate consideration received by the Corporation for the total number of Additional Shares of Common so issued would purchase at such Conversion Price, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of such Additional Shares of Common so issued.

(2)    Notwithstanding the foregoing, in no instance shall any Conversion Price be reduced if at such time the amount of such reduction would be less than $0.01, but any such amount shall be carried forward, and a reduction will be made with respect to such amount at the time of, and together with, any subsequent reduction which, together with such amount and any other amounts so carried forward, equal $0.01 or more in the aggregate. For the purposes of this Subsection 4(c)(iv), all shares of Common Stock issuable upon conversion of all outstanding shares of Preferred Stock and the exercise and/or conversion of any other outstanding Convertible Securities and all outstanding Options shall be deemed to be outstanding.

(v)    Determination of Consideration. For purposes of this subsection 4(d), the consideration received by the Corporation for the issue (or deemed issue) of any Additional Shares of Common shall be computed as follows:

(1)    Cash and Property. Such consideration shall:

(a)    insofar as it consists of cash, be computed at the aggregate amount of cash received by the Corporation before deducting any reasonable discounts, commissions or other expenses allowed, paid or incurred by the Corporation for any underwriting or otherwise in connection with such issuance;

(b)    insofar as it consists of property other than cash, be computed at the fair market value thereof at the time of such issue, as determined in good faith by the Board of Directors; and

12

(c)    in the event Additional Shares of Common 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 reasonably determined in good faith by the Board of Directors.

(2)    Options and Convertible Securities. The consideration per share received by the Corporation for Additional Shares of Common deemed to have been issued pursuant to paragraph 4(c)(iii) 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.

(e)    Adjustments for Subdivisions or Combinations of Common Stock. In the event the outstanding shares of Common Stock shall be subdivided (by stock split, by payment of a stock dividend or otherwise), into a greater number of shares of Common Stock, the Conversion Price of each series of Preferred Stock in effect immediately prior to such subdivision shall, concurrently with the effectiveness of such subdivision, be proportionately decreased. In the event the outstanding shares of Common Stock shall be combined (by reclassification or otherwise) into a lesser number of shares of Common Stock, the Conversion Prices in effect immediately prior to such combination shall, concurrently with the effectiveness of such combination, be proportionately increased.

(f)    Adjustments for Subdivisions or Combinations of Preferred Stock. In the event the outstanding shares of Preferred Stock or a series of Preferred Stock shall be subdivided (by stock split, by payment of a stock dividend or otherwise), into a greater number of shares of Preferred Stock, the Dividend Rate, and Original Issue Price of the affected series of Preferred Stock in effect immediately prior to such subdivision shall, concurrently with the effectiveness of such subdivision, be proportionately decreased. In the event the outstanding shares of Preferred Stock or a series of Preferred Stock shall be combined (by reclassification or otherwise) into a lesser number of shares of Preferred Stock, the Dividend Rate and Original Issue Price of the affected series of Preferred Stock in effect immediately prior to such combination shall, concurrently with the effectiveness of such combination, be proportionately increased.

(g)    Adjustments for Reclassification, Exchange and Substitution. Subject to Section 3, if the Common Stock issuable upon conversion of the Preferred Stock shall be changed into the same or a different number of shares of any other class or classes of stock, whether by capital reorganization, reclassification or otherwise (other than a subdivision or combination of shares provided for above), then, in any such event, in lieu of the number of shares of Common Stock which the holders would otherwise have been entitled to receive each holder of such Preferred Stock shall have the right thereafter to convert such shares of Preferred Stock into a number of shares of such other class or classes of stock which a holder of the number of shares of Common Stock deliverable upon conversion of such series of Preferred Stock immediately before that change would have been entitled to receive in such reorganization or reclassification, all subject to further adjustment as provided herein with respect to such other shares.

13

(h)    Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price pursuant to this Section 4, the Corporation at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof 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. The 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 (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 Preferred Stock.

(i)    Waiver of Adjustment of Conversion Price. Notwithstanding anything herein to the contrary, any downward adjustment of the Conversion Price of the Series A Preferred Stock may be waived by the consent or vote of the holders of a majority of the outstanding shares of Series A Preferred Stock (voting as a separate class) and including Maveron. Any downward adjustment of the Conversion Price of the Series B Preferred Stock or the Series B-1 Preferred Stock may be waived, in whole or in part, by the consent or vote of the holders of a majority of the outstanding shares of Series B Preferred Stock and Series B-1 Preferred Stock (voting together as a single and separate class on an as-converted basis) and including NEA. Any downward adjustment of the Conversion Price of the Series C Preferred Stock or the Series C-1 Preferred Stock may be waived, in whole or in part, by the consent or vote of the holders of a majority of the outstanding shares of Series C Preferred Stock and Series C-1 Preferred Stock (voting together as a single and separate class on an as-converted basis) and including both (i) NEA and (ii) Pivotal. Any downward adjustment of the Conversion Price of the Series D Preferred Stock may be waived by the consent or vote of the holders of a majority of the outstanding shares of Series D Preferred Stock (voting as a separate class).

(j)    Notices of Record Date. In the event that this Corporation shall propose at any time:

(i)    to declare any 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 effect any reclassification or recapitalization of its Common Stock outstanding involving a change in the Common Stock; or

(iii)    to voluntarily liquidate or dissolve or to enter into any transaction deemed to be a liquidation, dissolution or winding up of the corporation pursuant to Section 3(d);

then, in connection with each such event, this Corporation shall send to the holders of the Preferred Stock prior written notice of the date on which a record shall be taken for such Distribution (and specifying the date on which the holders of Common Stock shall be entitled thereto and, if applicable, the amount and character of such Distribution) or for determining rights to vote in respect of the matters referred to in (ii) and (iii) above.

Such written notice shall be given by first class mail (or express courier), postage prepaid, addressed to the holders of Preferred Stock at the address for each such holder as shown on the books of the Corporation and shall be deemed given on the date such notice is mailed.

The notice provisions set forth in this section may be shortened or waived prospectively or retrospectively by the consent or vote of the Requisite Preferred Holders, which shall include each of (i) Maveron, (ii) NEA, (iii) Pivotal, (iv) Gilde and (v) Longitude.

14

(k)    Reservation of Stock Issuable Upon Conversion. The 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 then 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, 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.

5.    Voting.

(a)    Restricted Class Voting. Except as otherwise expressly provided herein or as required by law, the holders of Preferred Stock and the holders of Common Stock shall vote together and not as separate classes.
