5. Rights, Preferences, Privileges and Restrictions. The rights, preferences, privileges, restrictions and other matters relating to the Preferred Stock are as follows:

5.1 Dividends.

(a) Mandatorily Convertible Preferred.

(i) The holders of record of the Mandatorily Convertible Preferred shall be entitled to receive dividends out of funds legally available therefor, to be paid quarterly in arrears on each three-month anniversary (each, a "Dividend Payment Date") of March 8, 2007 (the "Original Issuance Date") in preference and priority to any payment of any dividend on the Series D-1 Preferred, the Series D Preferred, the Series C Preferred, the Series B Preferred, the Series A Preferred or the Common Stock of the Corporation for such three-month period. Such dividends shall accrue daily and shall be computed on the basis of a 360-day year comprised of twelve 30-day months, at a rate equal to (a) during the period beginning on the Original Issuance Date and ending on the day immediately prior to the second anniversary thereof, five percent (5%) per annum (subject to any increase in such rate as provided in subsections (ii) or (iii) below) of the sum of (i) the Mandatorily Convertible Preferred Original Issue Price plus (ii) all unpaid dividends on such share of Mandatorily Convertible Preferred at the rate specified in this Section 5.1 that had accrued as of the most recent Dividend Payment Date, whether or not such dividends have been declared, plus (iii) any additional dividends declared and unpaid on such share of Mandatorily Convertible Preferred (the "Dividend Adjusted Mandatorily Convertible Preferred Original Issue Price") or (b) during the period commencing on the second anniversary of the Original Issuance Date, ten percent (10%) per annum (subject to any increase in such rate as provided in subsections (ii) or (iii) below) of the Dividend Adjusted Mandatorily Convertible Preferred Original Issue Price. In the event that any Dividend Payment Date occurs on a date which is not a business day, then the dividends that would otherwise have been payable on such Dividend Payment Date shall be paid on the next succeeding business day and will be treated for all purposes as though they were paid on the original Dividend Payment Date and no additional dividends will accrue for such period beginning at the Dividend Payment Date and ending on the next succeeding business day. During the period beginning on the Original Issuance Date and ending on the second anniversary thereof, the Corporation shall have the option to pay any required dividend payment on the Mandatorily Convertible Preferred in cash to the extent the Corporation has funds legally available therefore. To the extent such dividend payment is not paid in cash, such dividend payment shall be paid upon the conversion or redemption of such shares of Mandatorily Convertible Preferred in accordance with this Amended and Restated Certificate of Incorporation. If, during the period commencing on the Original Issuance Date and ending on the second anniversary thereof, the Corporation elects to pay any dividends on the Mandatorily Convertible Preferred in cash, the Corporation shall provide each holder of Mandatorily Convertible Preferred with at least 20 business days' prior written notice of the date such dividends shall be paid in cash by the Corporation. The Corporation shall be required to pay all dividends that accrue on the Mandatorily Convertible Preferred following the second anniversary of the Original Issuance Date in cash to the extent the Corporation has funds legally available therefore. To the extent that the Corporation does not have sufficient funds legally available for the payment of any dividend payment required to be made pursuant to this paragraph following the second anniversary of the Original Issuance Date, it shall pay such dividend to the holders of the Mandatorily Convertible Preferred on a pro rata basis (based on the

portion of such dividend payable to them) to the extent possible and shall pay the remainder of such dividend (or any portion thereof) as soon as sufficient funds are legally available. All cash payments of dividends by the Corporation on shares of Mandatorily Convertible Preferred shall be paid in United States dollars by check drawn on an account maintained at a bank in the City of New York, or if the amount to be paid to any single holder is in excess of $2,000,000, by wire transfer to an account maintained by such holder at a bank located in the City of New York. The record date for the payment of dividends on the Mandatorily Convertible Preferred shall be the date 15 calendar days prior to each Dividend Payment Date, whether or not a business day.

(ii) During any period in which a Filing Failure (as defined below) shall have occurred and remain in effect, the applicable per annum rate described in subsection (i) above at which the Mandatorily Convertible Preferred is then accruing dividends shall be increased by one (1) percentage point (e.g., from 5% to 6% of the Dividend Adjusted Mandatorily Convertible Preferred Original Issue Price). During any period in which an Effectiveness Failure (as defined below) shall have occurred and remain in effect, the applicable per annum rate described in subsection (i) above at which the Mandatorily Convertible Preferred is then accruing dividends shall be increased by two (2) percentage points (e.g., from 5% to 7% of the Dividend Adjusted Mandatorily Convertible Preferred Original Issue Price). For purposes of clarification, any increase in the applicable rate at which the Mandatorily Convertible Preferred accrues dividends that results from a Filing Failure or an Effectiveness Failure shall be in addition to, and not in lieu of, any increase in such rate that results from an Effectiveness Failure or Filing Failure, respectively.

(iii) Notwithstanding anything to the contrary contained herein, during any period in which a Minor Triggering Event or a Major Triggering Event (each as defined below) shall have occurred and remain in effect, the rate at which the Mandatorily Convertible Preferred shall accrue dividends shall be equal to fifteen percent (15%) per annum of the Dividend Adjusted Mandatorily Convertible Preferred Original Issue Price. For purposes of clarification, the rate set forth in this subsection (iii) shall be in lieu of, and not in addition to, the rates set forth in subsection (i) and any rate increases resulting from a Filing Failure or an Effectiveness Failure as set forth in subsection (ii) above.

As used herein, "Effectiveness Failure" means that either (i) by the 18-month anniversary of the Original Issuance Date a Qualifying Registration Statement (as defined below) has not been declared effective by the Securities Exchange Commission ("SEC") or (ii) at any time after the 18-month anniversary of the Original Issuance Date the SEC enters, or there continues to be in effect, a stop order with respect to a previously filed Qualifying Registration Statement.

As used herein, "Filing Failure" means that, at any time after the nine-month anniversary of the Original Issuance Date, the Corporation has not filed with the SEC a Qualifying Registration Statement.

As used herein, "Qualifying IPO" means the sale by the Corporation of shares of Common Stock in a firm commitment, fully underwritten public offering conducted primarily in the United States through a nationally recognized investment banking firm and pursuant to one or more registration statements under the Securities Act of 1933, as amended (the "Securities Act"), the public offering price of which is not less than $8.95 per share, the total public offering price (that is, before deducting underwriting discounts, commissions and fees) of which, but without regard to any underwriter over-allotment opinion, exceeds $60 million and after which the shares of Common Stock are listed or quoted on the New York Stock Exchange, Inc., the American Stock Exchange or the NASDAQ Global Market.

As used herein, "Qualifying Registration Statement" means a registration statement on Form S-1 (or any successor form specified by the SEC for the registration under the Securities Act, of the offer and sale of securities for cash) contemplating a transaction that, if completed, would be a Qualifying IPO (regardless of whether such registration statement, as so filed, indicates an estimated total or per share public offering price or price range), including the identification of the book-running underwriter or underwriters.

(b) Series D-1 Preferred. No dividend shall be declared, paid or set aside for payment with respect to the Series D-1 Preferred in any year until dividends have been paid or set apart for payment on the Mandatorily Convertible Preferred for the current year in which a dividend is to be paid on the Series D-1 Preferred. In the event that the Board of Directors shall have declared and paid, or set apart for payment, all dividends on the Mandatorily Convertible Preferred at the rate specified in Section 5.1(a) for the then current fiscal year and shall elect to declare additional dividends in that fiscal year out of funds legally available therefor, the holders of record of the Series D-1 Preferred shall be entitled to receive dividends, when and if declared by the Board of Directors of the Corporation out of funds legally available therefor, at a per share rate equal to Twenty Eight Cents ($0.28) per fiscal year (as proportionately adjusted for any stock dividend, combinations, splits, and other recapitalizations), payable in preference and priority to any payment of any dividend on the Series D Preferred, the Series C Preferred, the Series B Preferred, the Series A Preferred or the Common Stock of the Corporation for such year; provided, however, that such a dividend on the Series D-1 Preferred shall require the vote or written consent of a majority of the outstanding Common Stock and Series A Preferred Stock, voting together as a single class. No dividend rights shall accrue to holders of the Series D-1 Preferred when dividends on said shares are not declared in any year or years (except as is provided in Section 5.2(b) below).

No dividend rights shall accrue to holders of the Series C Preferred when dividends on said shares are not declared in any year or years (except as is provided in Section 5.2(d) below).

into which such share of Series B, C, D or D-1 Preferred on the record date for such dividend payment is convertible.

Except as required by law or as otherwise provided herein, the shares of Series Preferred shall be voted together with the Corporation's Common Stock at any annual or special meeting of the shareholders of the Corporation, or may act by written consent in the same manner as the Corporation's Common Stock, and shall have the voting rights and powers equal to the voting rights of the Common Stock, upon the following basis: The holder of each share of Common Stock issued and outstanding shall have one vote for each share so held, and each holder of shares of Series Preferred, regardless of series, shall be entitled to such number of votes for the Series Preferred held by the holder on the record date fixed for such meeting, or, if no record date is established, at the date such vote is taken or on the effective date of any such written consent, as shall be equal to the whole number of shares of Common Stock of the Corporation into which the holder's shares of Series Preferred are convertible immediately after the close of business on the record date fixed for such meeting, the date of such vote, or the effective date of such written consent. Holders of Common Stock and Series Preferred shall be entitled to notice of any shareholders meeting in accordance with the Bylaws of the Corporation. Fractional votes by the holders of the Series Preferred shall not, however, be permitted, and any fractional voting rights that would otherwise result shall (after aggregating all shares into which shares of Series Preferred held by each holder could be converted) be rounded down to the nearest whole number. Except as specifically set forth herein (including pursuant to Section 5.3(b)(iii) below) or as otherwise required by law, the holders of the Mandatorily Convertible Preferred shall not be entitled to any voting rights with respect to such shares of Mandatorily Convertible Preferred.

(b) Number of Directors and Voting for Directors.

(i) The authorized number of directors of the Corporation shall be eight (8). For so long as an aggregate of at least 5,000,000 shares (as proportionately adjusted for stock splits, stock dividends and other recapitalizations) of Series B, C, D and D-1 Preferred are outstanding, (i) the holders of the Series A Preferred and the Common Stock, voting together as a single class as provided in subsection (a) above, shall be entitled to elect two (2) directors (each, a "Series A/Common Director"); (ii) the holders of shares of

Series B, C, D and D-1 Preferred, voting as a single class, shall be entitled to elect four (4) directors (each, a "Series B/C/D/D-1 Director"); and (iii) the holders of the Series Preferred and the holders of Common Stock, voting as a single class as provided in subsection (a) above, shall be entitled to elect the remaining directors. If less than an aggregate of 5,000,000 shares (as proportionately adjusted for stock splits, stock dividends and other recapitalizations) of the Series B, C, D and D-1 Preferred shall remain outstanding, then all directors shall be elected by the holders of Series Preferred and Common Stock, voting as a single class as provided in subsection (a) above. Every stockholder entitled to vote at an election for directors may cumulate such stockholder's votes and give one candidate a number of votes equal to the number of directors to be elected by such stockholder multiplied by the number of votes to which such stockholder's shares are otherwise entitled, or distribute the stockholder's votes on the same principle among as many candidates as such stockholder thinks fit. No stockholder, however, shall be entitled to so cumulate such stockholder's votes unless (a) the names of such candidate or candidates have been placed in nomination prior to the voting and (b) the stockholder has given notice at the meeting, prior to the voting, of such stockholder's intention to cumulate such stockholder's votes. If any stockholder has given proper notice to cumulate votes, all stockholders may cumulate their votes for any candidates in the class to which they are entitled to elect who have been properly placed in nomination. Under cumulative voting, the candidates receiving the highest number of votes, up to the number of directors to be elected, are elected.

(ii) Removal of Directors/Filling of Vacancies.

(1) Removal. Any director may be removed from office at any time with or without cause by the vote or consent of the holders of the outstanding class or classes with voting power entitled to elect such director; provided, however, that unless the entire class is removed, no individual director may be removed when the votes cast against such director's removal, or not consenting in writing to such removal, would be sufficient to elect that director if voted cumulatively at an election in which the same total number of votes were cast (or, if such action is taken by written consent, all shares entitled to vote were voted) and the entire number of directors authorized in such class at the time of such director's most recent election were then being elected.

(2) Vacancy.

a. Any vacancy on the Board of Directors occurring because of the death, resignation or removal of a Series B/C/D/D-1 Director shall be filled only by the vote or written consent of the holders of a majority of the outstanding Series B, C, D and D-1 Preferred, voting together as a single class, except that in the case of removal of a Series B/C/D/D-1 Director, any written consent to fill such vacancy shall be executed by the holders of all of the outstanding Series B, C, D and D-1 Preferred. Any vacancy on the Board of Directors occurring because of the death, resignation or removal of a Series A/Common Director shall be filled by the vote or written consent of the holders of the Series A Preferred and Common Stock voting as provided in subsection (a) above, except that in the case of removal of a Series A/Common Director, any written consent to fill such vacancy shall be executed by the holders of all of the outstanding Series A Preferred and Common Stock. Any vacancy occurring because of the death, resignation or removal of a director elected by the vote of the Common Stock and the Series Preferred shall be filled by the vote or written consent of the holders of the Series Preferred and the Common Stock voting as provided in

subsection (a) above, except that in the case of removal of such a director, any written consent to fill such vacancy shall be executed by the holders of all of the outstanding Series Preferred and Common Stock. Any vacancy on the Board of Directors occurring because of the death, resignation or removal of a Mandatorily Convertible Preferred Director (as defined below) shall be filled only by the vote or written consent of the holders of a majority of the outstanding shares of Mandatorily Convertible Preferred, voting together as a single class, except that in the case of removal of a Mandatorily Convertible Preferred Director, any written consent to fill such vacancy shall be executed by the holders of all of the outstanding Mandatorily Convertible Preferred.

b. At any time or times that the Corporation is subject to Section 2115(b) of the California General Corporation Law (the "CGCL"), if, after the filling of any vacancy by the directors then in office who have been elected by stockholders shall constitute less than a majority of the directors then in office, then:

i. Any holder or holders of an aggregate of five percent (5%) or more of the total number of shares at the time outstanding having the right to vote for those directors may call a special meeting of stockholders; or

ii. The Superior Court of the proper county shall, upon application of such stockholder or stockholders, summarily order a special meeting of stockholders, to be held to elect the entire board, all in accordance with Section 305(c) of the CGCL. The term of office of any director shall terminate upon that election of a successor.

(iii) Notwithstanding anything to the contrary set forth in subsection (i) above, beginning upon the occurrence of:

(1) a Minor Triggering Event (as defined below) and continuing until the earlier of (i) the conversion or redemption of all outstanding shares of Mandatorily Convertible Preferred or (ii) the occurrence of a Major Triggering Event (as defined below), (x) the holders of Mandatorily Convertible Preferred shall be entitled to elect two (2) directors; (y) the holders of the Series A Preferred and the Common Stock, voting together as a single class as provided in subsection (a) above, shall be entitled to elect two (2) Series A/Common Directors; and (z) the holders of shares of Series B, C, D and D-1 Preferred, voting as a single class, shall be entitled to elect four (4) Series B/C/D/D-1 Directors. If less than an aggregate of 5,000,000 shares (as proportionately adjusted for stock splits, stock dividends and other recapitalizations) of the Series B, C, D and D-1 Preferred shall remain outstanding, then, (x) the holders of Mandatorily Convertible Preferred shall be entitled to elect two (2) directors; and (y) all remaining directors shall be elected by the holders of Series Preferred and Common Stock, voting as a single class as provided in subsection (a) above.

(2) a Major Triggering Event and continuing until the conversion or redemption of all outstanding shares of Mandatorily Convertible Preferred, (x) the holders of Mandatorily Convertible Preferred shall be entitled to elect five (5) directors; (y) the holders of the Series A Preferred and the Common Stock, voting together as a single class as provided in subsection (a) above, shall be entitled to elect one (1) Series A/Common Director; and (z) the holders of shares of Series B, C, D and D-1 Preferred, voting as a single class, shall be entitled to elect two (2) Series B/C/D/D-1 Directors. If less than an aggregate of 5,000,000 shares (as proportionately adjusted

for stock splits, stock dividends and other recapitalizations) of the Series B, C, D and D-1 Preferred shall remain outstanding, then, (x) the holders of Mandatorily Convertible Preferred shall be entitled to elect five (5) directors; and (y) all remaining directors shall be elected by the holders of Series Preferred and Common Stock, voting as a single class as provided in subsection (a) above.

All directors elected by the holders of the Mandatorily Convertible Preferred pursuant to this Section 5.3(b)(iii) shall be referred to herein as the "Mandatorily Convertible Preferred Directors". All other directors of the Corporation shall continue to be appointed pursuant to subsection (i) above. For purposes of clarification, holders of Series Preferred shall not be entitled to vote for the election or (for so long as any shares of Mandatorily Convertible Preferred remain outstanding) removal of any director elected pursuant to this subsection (iii).

(iv) Each of the following events shall constitute a "Minor Triggering Event" for purposes of this Amended and Restated Certificate of Incorporation:

(1) the failure by the Corporation to pay to any holder of Mandatorily Convertible Preferred all cash dividends payable on any Dividend Payment Date that occurs after the second anniversary of the Original Issuance Date within 60 days of such Dividend Payment Date;

(2) a default, which is not cured in 60 days, under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness (as defined below) for money borrowed by the Corporation or any of its Subsidiaries (as defined below) (or the payment of which is guaranteed by the Corporation or any of its Subsidiaries), whether such Indebtedness or guarantee exists on the Original Issuance Date, or is created thereafter, provided that such default:

a. is caused by a failure to pay principal or a premium, if any, or interest on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a "Payment Default"); or

b. results in the acceleration of such Indebtedness prior to its express maturity,

and, in each case, the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been accelerated, aggregates $5,000,000 or more;

(3) a final judgment or judgments for the payment of money aggregating in excess of $5,000,000 are rendered against the Corporation or any of its Subsidiaries and which judgments are not, within 60 days after the entry thereof, bonded, discharged or stayed pending appeal, or are not discharged within 60 days after the expiration of such stay; provided, however, that any judgment which is covered by insurance or an indemnity from a party determined by the Board of Directors to be credit-worthy shall not be included in calculating the $5,000,000 amount set forth above so long as the Corporation provides the holders of Mandatorily Convertible Preferred, upon request, with a written statement from such insurer or indemnity provider (which written statement shall be reasonably satisfactory to the holders of a majority of the outstanding shares of Mandatorily Convertible Preferred) to the effect that such judgment is covered by insurance or an indemnity and the

Corporation will receive the proceeds of such insurance or indemnity within 60 days of the issuance of such judgment; or

(4) the Corporation breaches or violates in any material respect any covenant, agreement, representation or warranty in (A) the Subscription Agreement dated on or about the Original Issuance Date by and among the Corporation and the holders of the Mandatorily Convertible Preferred (the "Subscription Agreement"), (B) the Registration Rights Agreement dated on or about the Original Issuance Date by and among the Corporation and the holders of the Mandatorily Convertible Preferred or (C) this Amended and Restated Certificate of Incorporation, and such breach or violation continues for a period of at least 60 days after written notice thereof to the Corporation from holders of at least 25% of the outstanding shares of Mandatorily Convertible Preferred.

(v) Each of the following events shall constitute a "Major Triggering Event" for purposes of this Amended and Restated Certificate of Incorporation:

(1) the continuance of an existing Minor Triggering Event or the occurrence of a new Minor Triggering Event following the fourth anniversary of the Original Issuance Date;

(2) the Corporation fails to redeem all shares of Mandatorily Convertible Preferred on the Final Redemption Date (as defined below);

(3) the Corporation or any of its Subsidiaries, pursuant to or within the meaning of Title 11, U.S. Code, or any similar federal, foreign or state law for the relief of debtors (collectively, "Bankruptcy Law"), (A) commences a voluntary case, (B) consents to the entry of an order for relief against it in an involuntary case, (C) consents to the appointment of a receiver, trustee, assignee, liquidator or similar official (a "Custodian"), (D) makes a general assignment for the benefit of its creditors or (E) admits in writing that it is generally unable to pay its debts as they become due; or

(vi) The following defined terms shall have the following meanings for purposes of this Amended and Restated Certificate of Incorporation:

(1) "Contingent Obligation" means any direct or indirect liability, contingent or otherwise, of a person or entity with respect to any indebtedness, lease, dividend or other obligation of another person or entity if the primary purpose or intent of the person or entity incurring such liability, or the primary effect thereof, is to provide assurance to the obligee of such liability that such liability will be paid or discharged, or that any agreements relating thereto will be complied with, or that the holders of such liability will be protected (in whole or in part) against loss with respect thereto;

(2) "Indebtedness" means, without duplication (a) all indebtedness for borrowed money, (b) all obligations issued, undertaken or assumed as the deferred purchase price of property or services including, without limitation, "capital leases" in accordance with Generally Accepted Accounting Principles ("GAAP") (other than trade payables entered into in the ordinary course of business), (c) all reimbursement

(3) "Subsidiary" means with respect to any person or entity, any corporation, association or other business entity of which more than 50% of the total voting power of shares of capital stock entitled (without regard to the occurrence of any contingency) to vote in the election of directors, managers or trustees or other governing body thereof is at the time owned or controlled by such person or entity (regardless of whether such equity is owned directly or through one or more other Subsidiaries of such person or entity or a combination thereof).

5.4 Conversion Rights. The holders of Preferred Stock shall have conversion rights as follows:

(a) Conversion Price.

(i) Each share of Series Preferred shall be convertible into the number of shares of Common Stock that results from dividing its respective Original Purchase Price (as defined below) by its respective Conversion Price (as defined below) in effect at the time of conversion. Each share of Mandatorily Convertible Preferred shall be convertible into the number of shares of Common Stock that results from dividing (A) the sum of (i) the Mandatorily Convertible Preferred Original Issue Price plus (ii) all accrued and unpaid dividends on such share of Mandatorily Convertible Preferred at the rate specified in Section 5.1(a) whether or not such dividends have been declared, plus (iii) any additional dividends declared and unpaid on such share of Mandatorily Convertible Preferred, by (B) the Conversion Price of the Mandatorily Convertible Preferred.

(ii) As used herein, the Series A Original Purchase Price for each share of Series A Preferred shall be Twenty-Five Cents ($0.25), the Series B Original Purchase Price for each share of Series B Preferred shall be One Dollar and Forty-Seven Cents ($1.47), the

Series C Original Purchase Price for each share of Series C Preferred shall be Three Dollars and Fifty Cents ($3.50), the Series D Original Purchase Price for each share of Series D Preferred shall be Ten Dollars ($10.00), the Series D-1 Original Purchase Price for each share of Series D-1 Preferred shall be Three Dollars and Fifty Cents ($3.50) and the Mandatorily Convertible Preferred Original Purchase Price for each share of Mandatorily Convertible Preferred shall be One Thousand Dollars ($1,000.00). Such Original Purchase Prices shall be subject to proportional adjustment from time to time to reflect stock splits, stock combinations, stock dividends and other recapitalizations affecting the shares of such series of Preferred Stock.

(iii) The price at which shares of Common Stock shall be deliverable upon conversion of the Preferred Stock (the "Conversion Price") shall initially be Twenty-Five Cents ($0.25) per share for Series A Preferred, One Dollar and Forty-Seven Cents ($1.47) per share for Series B Preferred, Three Dollars and Fifty Cents ($3.50) per share for Series C Preferred, Ten Dollars ($10.00) per share for Series D Preferred and Three Dollars and Fifty Cents ($3.50) per share for Series D-1 Preferred. The Conversion Price of the Mandatorily Convertible Preferred shall be determined at the time of the conversion of such shares of Mandatorily Convertible Preferred and shall be determined as follows:

(1) In the event that any shares of Mandatorily Convertible Preferred are converted into shares of Common Stock pursuant to paragraph (b) below, the Conversion Price of the Mandatorily Convertible Preferred shall be equal to Eleven Dollars and Seventy Cents ($11.70) per share (the "Maximum Conversion Price"); or

(2) In the event that the Mandatorily Convertible Preferred is converted into shares of Common Stock pursuant to paragraph (c)(i) below in connection with a Qualifying IPO, the Conversion Price of the Mandatorily Convertible Preferred shall be equal to lesser of (a) the Maximum Conversion Price and (b) the greater of (i) Seven Dollars and Eighty Five Cents ($7.85) per share (the "Minimum Conversion Price") and (ii) 87.5% of the initial price per share to the public of Common Stock issued and sold by the Corporation in a Qualifying IPO.

The initial Conversion Prices of the Preferred Stock shall be subject to adjustment from time to time as provided herein.

(b) Voluntary Conversion. Each share of Preferred Stock shall be converted into fully paid and nonassessable shares of Common Stock of the Corporation pursuant to Section 5.4(a) above, at the option of the holder thereof exercised by delivery of a written notice to the Secretary of the Corporation, and delivery of certificates as provided herein.

(c) Automatic Conversion.

(i) Each share of Mandatorily Convertible Preferred shall automatically be converted into fully paid and nonassessable shares of Common Stock, at the then effective Conversion Price for such share of Mandatorily Convertible Preferred, in the manner provided herein, in the event of the closing of a Qualifying IPO. In the event of an offering described in the preceding sentence, the person(s) entitled to receive the Common Stock issuable upon such conversion of Mandatorily Convertible Preferred shall not be deemed to have converted until immediately prior to the closing of such sale of securities.

(ii) Each share of Series Preferred shall automatically be converted into fully paid and nonassessable shares of Common Stock, at the then effective respective Conversion Price for such share of Series Preferred, in the manner provided herein, (i) in the event

of the closing of an underwritten public offering pursuant to an effective registration statement under the Securities Act of 1933, as amended, covering the offer and sale of Common Stock for the account of the Corporation and resulting in the receipt by the Corporation (prior to underwriters' commissions and offering expenses) of at least Twenty Million Dollars ($20,000,000) at a purchase price of not less than Ten Dollars ($10.00) per share (as proportionately adjusted to reflect stock splits, stock combinations, stock dividends and other recapitalizations), or (ii) on such date as is approved by the holders of (a) at least a majority of the shares of the Series A Preferred then outstanding, voting together as a separate class, (b) at least two-thirds (²/3) of the shares of the Series B Preferred then outstanding, voting together as a separate class, and (c) at least two-thirds (²/3) of the shares of Series C Preferred, Series D Preferred and Series D-1 Preferred then outstanding, voting together as a separate class. In the event of an offering described in clause (i) above, the person(s) entitled to receive the Common Stock issuable upon such conversion of Preferred Stock shall not be deemed to have converted until immediately prior to the closing of such sale of securities.

(d) Certificates. Before any holder of shares of Preferred Stock shall be entitled to convert the same into shares of Common Stock, such holder shall surrender the certificate or certificates therefor, duly endorsed in blank or accompanied by proper instruments of transfer, at the office of the Corporation's Secretary or its transfer agent, and shall at such time give written notice to the Corporation at such office that such holder elects to convert the same; provided, however, that in the event of an automatic conversion pursuant to Section 5.4(c), the outstanding shares of Preferred Stock shall be converted automatically without any further action of the holders of such shares and whether or not the certificates representing such shares are surrendered to the Corporation, and provided further that the Corporation or its transfer agent shall not be obligated to issue certificates evidencing the shares of Common Stock issuable upon such automatic conversion unless the certificates evidencing such shares are either delivered to the Corporation or its transfer agent or, if such certificates have been lost, stolen or destroyed, the shareholder executes an agreement satisfactory to the Corporation to indemnify the Corporation from any loss incurred by it in connection with such certificates. The Corporation, as soon as practicable thereafter, shall issue and deliver at such office to such holder, certificates for the full number of shares of Common Stock to which such holder shall be entitled. No fractional shares of Common Stock shall be issued by the Corporation. The holder of such fractional shares otherwise issuable shall be issued a check payable to the holder in the amount of any cash amounts, as reasonably determined by the Board of Directors (which, in the case of the Mandatorily Convertible Preferred, shall be based upon the price per share to the public of Common Stock issued and sold by the Corporation in a Qualifying IPO), payable as the result of a conversion into fractional shares of Common Stock. Such conversion shall be deemed to have been made as of the date of delivery of such notice and surrender of the shares of Preferred Stock to be converted, and the person or persons entitled to receive the Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such Common Stock on said date. The Corporation shall be responsible for the payment of any stock transfer, stamp, documentary and similar taxes (excluding any taxes on the income or gain of the holders of such shares) that may be payable with respect to the issuance and delivery of shares of Common Stock upon conversion of outstanding shares of Preferred Stock.

(e) Stock Dividends. In case the Corporation shall at any time subdivide the outstanding Common Stock, or issue a stock dividend on its outstanding Common Stock, the respective Conversion Prices of the shares of Series Preferred and the Maximum Conversion Price and the Minimum Conversion Price of the Mandatorily Convertible Preferred, immediately prior to such subdivision or the issuance of such stock dividend, shall be proportionately decreased; and in case the Corporation shall at any time combine or consolidate the outstanding shares of Common Stock, by reverse stock split or otherwise, the respective Conversion Prices of the shares of Series Preferred and the Maximum Conversion Price and the Minimum Conversion Price of the Mandatorily Convertible Preferred, immediately prior to such combination shall be proportionately increased. Any such changes shall be effective at the close of business on the date of such subdivision, stock dividend or combination, as the case may be.

(f) Adjustments for Distributions. In the event at any time or from time to time the Corporation makes any distribution to holders of its Common Stock (excluding any repurchases of securities by the Corporation not made on a pro rata basis from all holders of any class of the Corporation's securities and payable in property or in securities of the Corporation and other than as otherwise adjusted in this Section 5.4), then in such event the holder of each share of Preferred Stock shall receive at the time of such distribution the amount of property or the number of securities of the Corporation that such holder would have received had such holder's shares of Preferred Stock been converted into Common Stock (in the case of the Mandatorily Convertible Preferred, pursuant to Section 5.4(b) above) on the date set for determining the holders of Common Stock entitled to such distribution, or if no such date shall have been set, then on the date of such distribution.

(g) Reorganization. Except as provided in Section 5.2, in the case of any reorganization or any reclassification of the outstanding shares of Common Stock of the Corporation (other than a change in par value or from par value to no par value or from no par value to par value or as a result of a stock dividend or subdivision, split-up or combination of shares), or in the case of any consolidation or merger to which the Corporation is a party (except a merger in which the Corporation is the surviving corporation and which does not result in any reclassification of the outstanding Common Stock of the Corporation), the holder of each share of Preferred Stock then outstanding shall thereafter (or, in the case of the Mandatorily Convertible Preferred, in connection with a Qualifying IPO or a Change of Control) have the right to convert such share into the kind and amount of stock and other securities and property which would have been received upon such reorganization, reclassification, consolidation or merger by a holder of the number of shares of Common Stock of the Corporation into which such share of Preferred Stock was convertible immediately prior to such event. The provisions of this subparagraph (g) shall similarly apply to successive reorganizations, reclassifications, consolidations and mergers.

(h) Adjustments to Series B, C D and D-1 Conversion Price for Diluting Issues.

(i) Special Definitions. For purposes of this Section 5.4(h), the following definitions shall apply:

(1) "Options" shall mean rights, options or warrants to subscribe for, purchase or otherwise acquire either Common Stock or Convertible Securities.

(2) "Convertible Securities" shall mean any evidence of indebtedness, shares or other securities convertible into or exchangeable for Common Stock.

(3) "Additional Shares of Common Stock" shall mean with respect to each series of Senior Preferred, all shares of Common Stock issued (or, pursuant to

(ii) Deemed Issue of Additional Shares of Common Stock; Options and Convertible Securities. In the event the Corporation, at any time or from time to time after the Original Issuance Date, shall issue any Options or Convertible Securities (other than Options or Convertible Securities referred to in Section 5.4(h)(i)(3) above), then the maximum number of shares (as set forth in the instrument relating thereto without regard to any provisions contained therein for a subsequent adjustment of such number) of Common Stock issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Shares of Common Stock with respect to

such series of Series Preferred issued as of the time of such issue, provided that in any such case in which Additional Shares of Common Stock are deemed to be issued:

a. no further adjustment in the relevant Conversion Price(s) shall be made upon the subsequent issue of Convertible Securities or shares of Common Stock upon the exercise of such Options or conversion or exchange of such Convertible Securities;

b. if such Options or Convertible Securities by their terms provide, with the passage of time or otherwise, for any change in the amount of consideration payable to the Corporation, or change in the number of shares of Common Stock issuable, upon the exercise, conversion or exchange thereof, the relevant Conversion Price(s) computed upon the original issue thereof and any subsequent adjustments based thereon, shall, upon any such change becoming effective, be recomputed to reflect an appropriate increase or decrease reflecting such change insofar as it affects such Options or the rights of conversion or exchange under such Convertible Securities;

c. 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 relevant Conversion Price(s) computed upon the original issue thereof, and any subsequent adjustments based thereon, shall, upon such expiration, be recomputed as if:

i. in the case of Convertible Securities or Options for Common Stock, the only Additional Shares of Common Stock issued were shares of Common Stock, if any, actually issued upon the exercise of such Options or the conversion or exchange of such Convertible Securities and the consideration received therefor was the consideration actually received by the Corporation for the issue of all such Options, whether or not exercised, plus the consideration actually received by the Corporation upon such exercise, or for the issue of all such Convertible Securities which were actually converted or exchanged, plus the additional consideration, if any, actually received by the Corporation upon such conversion or exchange, and

ii. in the case of Options for Convertible Securities, only the Convertible Securities, if any, actually issued upon the exercise thereof were issued at the time of issue of such Options, and the consideration received by the Corporation for the Additional Shares of Common Stock deemed to have been then issued was the consideration actually received by the Corporation for the issue of all such Options, whether or not exercised, plus the consideration deemed to have been received by the Corporation upon the issue of the Convertible Securities with respect to which such Options were actually exercised;

d. no readjustment pursuant to clause (B) or (C) above shall have the effect of increasing the relevant Conversion Price(s) to an amount which exceeds the lower of (i) the Conversion Price on the original adjustment date for said deemed adjustment without giving effect to said deemed adjustment, or (ii) the Conversion Price that would have resulted from any actual issuance of Additional Shares of Common Stock between the original adjustment date and such readjustment date if said original adjustment had not been made; and

e. in the case of any Option which expires by its terms not more than thirty (30) days after the date of issue thereof, no adjustment of any Conversion Price shall be made until the expiration or exercise of such Option, whereupon such adjustment shall be made as of the date such Option was granted and otherwise in the same manner as provided in clause (C) above.

(iii) Issuance of Additional Shares of Common Stock for Less than Senior Preferred Conversion Price. If at any time or from time to time after the Original Issuance Date, the Corporation shall issue or sell Additional Shares of Common Stock (including Additional Shares of Common Stock deemed to be issued pursuant to Section 5.4(h)(ii)), other than as a dividend or other distribution on any class of stock as provided in Section 5.4(e) above, for consideration per share less than the then existing Conversion Price of the respective series of Senior Preferred (the "Senior Preferred Conversion Price"), then and in each such case the then existing Senior Preferred Conversion Price for that series shall be adjusted as of the opening of business on the date of such issue or sale, to a price determined by multiplying such Senior Preferred Conversion Price for that series by a fraction (i) the numerator of which shall be (A) the number of shares of Common Stock outstanding immediately prior to such issue or sale (assuming for this purpose that all outstanding Options and Convertible Securities are then converted into Common Stock), plus (B) the number of shares of Common Stock that the aggregate consideration received by the Corporation for the total number of Additional Shares of Common Stock so issued would purchase at such Senior Preferred Conversion Price, and (ii) the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue or sale (assuming for this purpose that all outstanding Options and Convertible Securities are then converted into Common Stock) plus the number of such Additional Shares of Common Stock so issued.

(iv) Determination of Consideration. For purposes of this Section 5.4(h), the consideration received by the Corporation for the issue of any Additional Shares of Common Stock shall be computed as follows:

a. Cash and Property. Such consideration shall:

i. insofar as it consists of cash, be computed at the aggregate amount of cash received by the Corporation (before commissions or expenses), excluding amounts paid or payable for accrued interest or accrued dividends;

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

iii. in the event Additional Shares of Common Stock are issued together with other shares or securities or other assets of the Corporation for consideration which covers both, be the proportion of such consideration so received, computed as provided in clauses (I) and (II) above, as determined in good faith by the Board.

b. Options and Convertible Securities. The consideration per share received by the Corporation for Additional Shares of Common Stock deemed to have been issued pursuant to Section 5.4(h)(ii) 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.

(i) Available Shares. The Corporation shall at all times reserve and keep available, out of its authorized but unissued Common Stock, solely for the purpose of effecting the conversion of the Preferred Stock, the full number of shares of Common Stock deliverable upon the conversion of all shares of Preferred Stock from time to time outstanding. The Corporation shall from time to time (subject to obtaining necessary director and stockholder action), in accordance with the laws of the State of Delaware, increase the authorized amount of its Common Stock if at any time the authorized number of shares of Common Stock remaining unissued shall not be sufficient to permit the conversion of all of the shares of Preferred Stock at the time outstanding.

(j) Notices. Any notices required by the provisions of this Section 5.4 to be given to the holders of Preferred Stock shall be deemed given at the time deposited in the United States mail, first-class postage prepaid and addressed to each holder of record at its address appearing on the books of the Corporation.

(k) No Impairment. Without obtaining the requisite consent of the holders of the outstanding shares of Preferred Stock as provided for herein or otherwise in accordance with applicable law, the Corporation will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Corporation but will at all times in good faith assist in the carrying out of all the provisions of this Section 5.4.

(l) Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of any Conversion Price of the Series Preferred or the Maximum Conversion Price or Minimum Conversion Price of the Mandatorily Convertible Preferred, in each case pursuant to this Section 5.4, the Corporation at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each holder of Series Preferred 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 Series Preferred, furnish or cause to be furnished to such holder a like certificate setting forth (i) such adjustments and readjustments, (ii) the Conversion Prices 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 Series Preferred.

(m) Prior Notice. In the event that the Corporation shall propose at any time:

(i) to declare any dividend or distribution (other than by purchase of Common Stock of employees, officers and directors pursuant to the termination of such persons or pursuant to the Corporation's exercise of rights of first refusal with respect to Common

stock held by such persons) upon its Common Stock, whether in cash, property, stock or other securities, whether or not a regular cash dividend and whether or not out of earnings or earned surplus;

(ii) to offer for subscription pro rata to the holders of any class or series of its stock any additional shares of stock of any class or series or other rights;

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

(iv) to merge or consolidate with or into any other corporation, or sell, lease or convey all or substantially all its property or business, or to liquidate, dissolve or wind up; or

(v) to otherwise effect a Fundamental Transaction;

then, in connection with each such event, the Corporation shall send to each holder of the Preferred Stock:

(1) at least twenty (20) days' prior written notice of the date on which a record shall be taken for such dividend, distribution or subscription rights (and specifying the date on which the holders of Common Stock shall be entitled thereto) or, in the case of the Series Preferred, for determining rights to vote in respect of the matters referred to in (i) and (ii) above; and

(2) in the case of the matters referred to in (iii), (iv) and (v) above, at least twenty (20) days' prior written notice of the date when the same shall take place (and specifying the date on which the holders of Common Stock shall be entitled to exchange their Common Stock for securities or other property deliverable upon the occurrence of such event).

The following will not be deemed to be transactions with Affiliates and, therefore, will not be subject to the provisions of this paragraph: any agreement or actions thereunder in effect as of the Original Issuance Date or any amendment, supplement, restatement, replacement, renewal, extension, refinancing thereof or thereto (so long as the renewed or replaced agreement is not materially more disadvantageous to the Corporation or such Subsidiary than the original agreement in effect on the Original Issuance Date as determined by a majority of the Corporation's directors not interested in any such transaction) or any transaction contemplated thereby.

5.6 Redemption of Mandatorily Convertible Preferred.

(a) The Corporation shall be obligated to redeem the Mandatorily Convertible Preferred as follows:

(i) If any shares of Mandatorily Convertible Preferred remain outstanding as of the fourth anniversary of the Original Issuance Date (the "Final Redemption Date"), the Corporation shall redeem on the Final Redemption Date, to the extent it may lawfully do so, all outstanding shares of Mandatorily Convertible Preferred by paying in cash an amount (as proportionately adjusted for stock splits, stock dividends and other recapitalizations) for each share of Mandatorily Convertible Preferred equal to the sum of (i) the Mandatorily Convertible Preferred Original Purchase Price, plus (ii) all accrued and unpaid dividends on each such share of Mandatorily Convertible Preferred at the rate specified in Section 5.1(a), plus (iii) any additional dividends declared and unpaid on each such share of Mandatorily Convertible Preferred. The total amount to be paid for the Mandatorily Convertible Preferred is hereinafter referred to as the "Redemption Price."

(ii) At least thirty (30) days but no more than sixty (60) days prior to the Final Redemption Date, the Corporation shall send a notice (a "Redemption Notice") to all holders of Mandatorily Convertible Preferred setting forth (A) the Redemption Price for the shares to be redeemed; and (B) the place at which such holders may obtain payment of the Redemption Price upon surrender of their share certificates. If the Corporation does not have sufficient funds legally available to redeem all shares to be redeemed at the Final Redemption Date, then it shall redeem such shares pro rata (based on the portion of the aggregate Redemption Price payable to them) to the extent possible and shall redeem the remaining shares to be redeemed as soon as sufficient funds are legally available.

(b) On or prior to the Final Redemption Date, the Corporation shall deposit the Redemption Price of all shares to be redeemed with a bank or trust company which is located in the City of New York, as a trust fund, with irrevocable instructions and authority to the bank or trust company to pay, on and after the Final Redemption Date, the Redemption Price of the shares to their respective holders upon the surrender of their share certificates. The balance of any funds deposited by the Corporation pursuant to this Section 5.6(b) remaining unclaimed at the expiration of one year following such Redemption Date shall be returned to the Corporation promptly upon its written request.

(c) On or after such Redemption Date, each holder of shares of Mandatorily Convertible Preferred shall surrender such holder's certificates representing such shares to the Corporation in the manner and at the place designated in the Redemption Notice, and thereupon the Redemption Price of such shares shall be payable to the order of the person whose name appears on such certificate or certificates as the owner thereof and each surrendered certificate shall be canceled. The Redemption Price shall be paid to the holders of the Mandatorily Convertible Preferred in United States dollars by check, or if the amount to be paid to any single holder is in excess of $2,000,000, by wire transfer to an account maintained by such holder at a bank located in the City of New York. In the event less than all the shares represented by such certificates are redeemed, a new certificate shall be issued representing the unredeemed shares. From and after such Final Redemption Date, unless there shall have been a default in payment of the Redemption Price or the Corporation is unable to pay the Redemption Price due to not having sufficient legally available funds, all rights of the holder of shares of Mandatorily Convertible Preferred (except the right to receive the Redemption Price without interest upon surrender of their certificates), shall cease and terminate with respect to such shares; provided that in the event that the shares of

Mandatorily Convertible Preferred are not redeemed due to a default in payment by the Corporation or because the Corporation does not have sufficient legally available funds, such shares of Mandatorily Convertible Preferred shall remain outstanding and shall be entitled to all of the rights and preferences provided herein.

5.7 No Reissuance of Mandatorily Convertible Preferred.

Any shares of Mandatorily Convertible Preferred acquired by the Corporation by reason of redemption, purchase, conversion or otherwise shall be cancelled, shall return to the status of authorized but unissued Preferred Stock of no designated series, and shall not be issuable by the Corporation as Mandatorily Convertible Preferred.

5.8 Lost or Stolen Certificates.

Upon receipt by the Corporation of (i) evidence of the loss, theft, destruction or mutilation of any certificates representing shares of Preferred Stock and (ii) (y) in the case of loss, theft or destruction, of indemnity (without any bond or other security) reasonably satisfactory to the Corporation, or (z) in the case of mutilation, upon surrender and cancellation of the certificates representing shares of Preferred Stock, the Corporation shall execute and deliver new certificates representing such shares of Preferred Stock of like tenor.

1. The liability of the directors of the Corporation for monetary damages shall be eliminated to the fullest extent under applicable law. If the DGCL is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Corporation shall be eliminated to the fullest extent permitted by the DGCL, as so amended.

2. The Corporation is authorized to provide indemnification of agents (as defined in Section 317 of the CGCL) for breach of duty to the Corporation and its stockholders through bylaw provisions or through agreements with the agents, or through stockholder resolutions, or otherwise, in excess of the indemnification otherwise permitted by Section 317 of the CGCL, subject, at any time or times that the Corporation is subject to Section 2115(b) of the CGCL, to the limits on such excess indemnification set forth in Section 204 of the CGCL.

3. Any repeal or modification of this Article V shall only be prospective and shall not affect the rights under this Article V in effect at the time of the alleged occurrence of any act or omission to act giving rise to liability or indemnification.

VI.

For the management of the business and for the conduct of the affairs of the Corporation, and in further definition, limitation and regulation of the powers of the Corporation, of its directors and of its stockholders or any class thereof, as the case may be, it is further provided that:

1. The management of the business and the conduct of the affairs of the Corporation shall be vested in its Board of Directors.

Subject to any restrictions that may be set forth in this Amended and Restated Certificate of Incorporation, each director shall serve until her successor is duly elected and qualified or until her death, resignation or removal. No decrease in the number of directors constituting the Board shall shorten the term of any incumbent director.

2. Subject to the rights of the holders of any series of Series Preferred that may come into existence from time to time, the Board of Directors is expressly empowered to adopt, amend or repeal

the Bylaws of the Corporation. The stockholders shall also have the power to adopt, amend or repeal the Bylaws of the Corporation subject to the terms of this Certificate of Incorporation; provided, however, that, in addition to any vote of the holders of any class or series of stock of the Corporation required by law or by this Amended and Restated Certificate of Incorporation, the affirmative vote of the holders of at least a majority of the voting power of all of the then-outstanding shares of the capital stock of the Corporation entitled to vote generally in the election of directors, voting together as a single class, shall be required for the stockholders to adopt, amend or repeal any provision of the Bylaws of the Corporation.

3. The directors of the Corporation need not be elected by written ballot unless the Bylaws so provide.

4. No action shall be taken by the stockholders of the Corporation except at an annual or special meeting of stockholders called in accordance with the Bylaws, by written consent or electronic transmission of stockholders in accordance with the Bylaws.

5. Advance notice of stockholder nominations for the election of directors and of business to be brought by stockholders before any meeting of the stockholders of the Corporation shall be given in the manner provided in the Bylaws of the Corporation.

VII.

The Corporation reserves the right to amend, alter, change or repeal any provision contained in this Amended and Restated Certificate of Incorporation, in the manner now or hereafter prescribed by statute and all rights conferred upon the stockholders herein are granted subject to this reservation.
