If the funds of this Corporation legally available for redemption of shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock, as applicable, on any Redemption Date are insufficient to redeem the total number of shares of such stock to be redeemed on such date, those funds that are legally available will be used to redeem the maximum possible number of such shares ratably among the holders of such shares to be redeemed such that each holder of a share of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock, as applicable, requesting redemption receives the same percentage of the Redemption Price. If the funds of this Corporation legally available for redemption of shares are insufficient to redeem the total number of shares of stock to be redeemed in any simultaneous or overlapping redemption of each of the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock, then the funds of this Corporation legally available for redemption shall be used to redeem the maximum number of shares requested to be redeemed ratably among the holders of the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock to be redeemed, in proportion to the amount each such holder is otherwise entitled to receive. The shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock not redeemed shall remain outstanding and entitled to all the rights and preferences provided herein.

(e) On or prior to each Redemption Date, this Corporation shall deposit the Redemption Price of all shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock, as applicable, designated for redemption in the Redemption Notice and not yet redeemed or converted with a bank or trust corporation having aggregate capital -9- and surplus in excess of $100,000,000 as a trust fund for the benefit of the respective holders of the shares designated for redemption and not yet redeemed, with irrevocable instructions and authority to the bank or trust corporation to publish the notice of redemption thereof and pay the applicable Redemption Price to their respective holders on or after the Redemption Date, upon receipt of notification from this Corporation that such holder has surrendered his, her or its share certificate to this Corporation pursuant to subsection (3)(c) above. As of the date of such deposit (even if prior to the Redemption Date), the deposit shall constitute full payment of the shares to their holders, and from and after the date of the deposit the shares so called for redemption shall be redeemed and shall be deemed to be no longer outstanding, and the holders thereof shall cease to be stockholders with respect to such shares and shall have no rights with respect thereto except the rights to receive from the bank or trust corporation payment of the applicable Redemption Price, without interest, upon surrender of their certificates therefor, and the right to convert such shares as provided in Article IV(B)(4) hereof. Such instructions shall also provide that any moneys deposited by this Corporation pursuant to this subsection (3)(e) for the redemption of shares thereafter converted into shares of this Corporation's Common Stock pursuant to Article IV(B)(4) hereof prior to the Redemption Date shall be returned to this Corporation forthwith upon such conversion.

Conversion. The holders of the Series A Preferred Stock, Series B ---------- Preferred Stock, Series C Preferred Stock and Series D Preferred Stock shall have conversion rights as follows (the "Conversion Rights"): (a) Right to Convert. Each share of Series A Preferred Stock, each ---------------- share of Series B Preferred Stock, each share of Series C Preferred Stock and each share of Series D Preferred Stock shall be convertible, at the option of the holder thereof, at any time after the date hereof and on or prior to the fifth day prior to the applicable Redemption Date, if any, as may have been fixed in any Redemption Notice with respect to the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock, as applicable, at the office of this Corporation or any transfer agent for such stock, into such number of fully paid and nonassessable shares of Common Stock as is determined by dividing the applicable Original Issue Price by the Conversion Price applicable to such share, determined as hereafter provided, in effect on the date the certificate is surrendered for conversion. The initial Conversion Price per share for shares of Series A Preferred Stock shall be the initial Original Issue Price of the Series A Preferred Stock, the initial Conversion Price per share for shares of Series B Preferred Stock shall be the initial Original Issue Price for the Series B Preferred Stock, the initial Conversion Price per share for shares of Series C Preferred Stock shall be the initial -10- Original Issue Price for Series C Preferred Stock, and the initial Conversion Price per share for shares of Series D Preferred Stock shall be the initial Original Issue Price for Series D Preferred Stock; provided, however, that the Conversion Price shall be subject to adjustment as set forth in subsection 4(d). (b) Automatic Conversion. -------------------- (i) Conversion at Option of Holders. If at any time the holders ------------------------------- of a majority of the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock then outstanding, voting together as a single class, so request by written consent delivered to the Corporation at its principal offices by facsimile transmission or any other customary means of delivery, then each outstanding share of Series A Preferred Stock, each outstanding share of Series B Preferred Stock, each outstanding share of Series C Preferred Stock and each outstanding share of Series D Preferred Stock shall automatically be converted into shares of Common Stock at the applicable Conversion Price at the time in effect for the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock, respectively, immediately upon the date specified in such written consent. (ii) Conversion upon Public Offering. ------------------------------- (A) Each outstanding share of Series A Preferred Stock, each outstanding share of Series B Preferred Stock, each outstanding share of Series C Preferred Stock and each outstanding share of Series D Preferred Stock shall automatically be converted into shares of Common Stock, at the Conversion Price set forth in (B) below, immediately upon the the closing of an initial public offering by the Corporation of the Common Stock, provided that the following shall not be considered a public offering: (i) any issuance of Common Stock as consideration for a merger, acquisition or SEC Rule 145 transaction, and (ii) any issuance of Common Stock or rights to acquire Common Stock to existing securityholders or to employees of the Company or its Subsidiaries on Form S-4 or Form S-8 (or any successor forms adopted by the Securities and Exchange Commission) or otherwise, irrespective of the jurisdiction in which such public offering is conducted, or at the latest possible time prior to such closing, if required by the principal securities exchange or market upon which the Common Stock will be listed or traded, the public offering price of which is not less than $10,000,000 in the aggregate and the public offering price of the Common Stock is no less than $7.50 per share (adjusted to reflect subsequent stock dividends, stock splits or recapitalizations). (B) In the event of the public offering described in 4(b)(ii)(A), the Conversion Price for each outstanding share of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock will be the applicable Conversion Price at the time in effect for the Series A -11- Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, as adjusted by the adjustment described in subparagraph 4(d)(v) below (i.e. the adjustment to be made in the event of a public offering, sale or merger of the Corporation in which the holders of the Common Stock receive at least $9.00 per share), and Series D Preferred Stock, respectively. (c) Mechanics of Conversion. Before any holder of Series A Preferred ----------------------- Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock shall be entitled to convert the same into shares of Common Stock, he or she shall surrender the certificate or certificates therefor, duly endorsed, at the office of this Corporation or of any transfer agent for the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock, as applicable, and shall give written notice to this Corporation at its principal corporate office of the election to convert the same and shall state therein the name or names in which the certificate or certificates for shares of Common Stock are to be issued. This Corporation shall, as soon as practicable thereafter, issue and deliver at such office to such holder, or to the nominee or nominees of such holder, a certificate or certificates for the number of shares of Common Stock to which such holder shall be entitled as aforesaid. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the shares to be converted, and the person or persons entitled to receive the shares of Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock as of such date. If the conversion is in connection with an underwritten offering of securities registered pursuant to the Securities Act of 1933, as amended, the conversion may, at the option of any holder tendering Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock for conversion, be conditioned upon the closing with the underwriters of the sale of securities pursuant to such offering, in which event the person(s) entitled to receive the Common Stock upon conversion of the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock shall not be deemed to have converted such Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock until immediately prior to the closing of such sale of securities. (d) Conversion Price Adjustments of Preferred Stock. (i) The ----------------------------------------------- Conversion Price of the Series A Preferred Stock, the Conversion Price of the Series B Preferred Stock, the Conversion Price of the Series C Preferred Stock and the Conversion Price of the Series D Preferred Stock shall be subject to adjustment from time to time as follows: (A) If after the date upon which any shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock are first issued (the "Purchase Date"), this Corporation shall issue any Additional Stock (as defined below) without consideration or for a consideration -12- per share less than the Conversion Price of the Series A Preferred Stock, the Conversion Price of the Series B Preferred Stock, the Conversion Price of the Series C Preferred Stock, or the Conversion Price of the Series D Preferred Stock in effect immediately prior to the issuance of such Additional Stock, then the Conversion Price of the Series D Preferred Stock (in the event the Additional Stock is issued for a consideration per share less than the Conversion Price of the Series D Preferred Stock but greater than the Conversion Price of the Series A Preferred Stock, the Conversion Price of the Series B Preferred Stock and the Conversion Price of the Series C Preferred Stock), both the Conversion Price of the Series C Preferred Stock and the Conversion Price of the Series D Preferred Stock (in the event the Additional Stock is issued for a consideration per share less than the Conversion Price of the Series C Preferred Stock and the Conversion Price of the Series D Preferred Stock but greater than the Conversion Price of the Series A Preferred Stock and the Conversion Price of the Series B Preferred Stock), each of the Conversion Price of the Series B Preferred Stock, the Conversion Price of the Series C Preferred Stock and the Conversion Price of the Series D Preferred Stock (in the event the Additional Stock is issued for a consideration per share less than the Conversion Price of the Series B Preferred Stock, the Conversion Price of the Series C Preferred Stock and the Conversion Price of the Series D Preferred Stock but greater than the Conversion Price of the Series A Preferred Stock) or each of the Conversion Price of the Series A Preferred Stock, the Conversion Price of the Series B Preferred Stock, the Conversion Price of the Series C Preferred Stock and the Conversion Price of the Series D Preferred Stock (in the event the Additional Stock is issued for a consideration per share less than the Conversion Price of each of the Series A Preferred Stock, the Series B Preferred Stock, the Series C Preferred Stock and the Series D Preferred Stock) in effect immediately prior to each such issuance shall forthwith (except as otherwise provided in this clause (i)) be adjusted to a price 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 issuance plus the number of shares of Common Stock that the aggregate consideration received by this Corporation for such issuance would purchase at such Conversion Price, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance plus the number of shares of such Additional Stock. For purposes of this subsection and the remainder of Sections 4(d)(i) and 4(d)(ii), Common Stock shall mean any shares of Common Stock issued (or deemed to have been issued pursuant to subsection 4(d)(i)(E)). (B) No adjustment of the Conversion Price for the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock shall be made in an amount less than one cent per share, provided that any adjustments that are not required to be made by reason of this sentence shall be carried forward and shall be either taken into account in any subsequent adjustment made prior to three years from the date of the event giving rise to the adjustment being carried forward, or shall be made at the end of three years from -13- the date of the event giving rise to the adjustment being carried forward. Except to the limited extent provided for in subsections (E)(3) and (E)(4), no adjustment of such Conversion Price pursuant to this subsection 4(d)(i) shall have the effect of increasing the Conversion Price above the Conversion Price in effect immediately prior to such adjustment. (C) In the case of the issuance of Common Stock for cash, the consideration shall be deemed to be the amount of cash paid therefor before deducting any reasonable discounts, commissions or other expenses allowed, paid or incurred by this Corporation for any underwriting or otherwise in connection with the issuance and sale thereof. (D) In the case of the issuance of Common Stock for a consideration in whole or in part other than cash, the consideration other than cash shall be deemed to be the fair value thereof as determined by the Board of Directors irrespective of any accounting treatment. (E) In the case of the issuance (whether before, on or after the Purchase Date) of options to purchase or rights to subscribe for Common Stock, securities by their terms convertible into or exchangeable for Common Stock, or options to purchase or rights to subscribe for such convertible or exchangeable securities, the following provisions shall apply for all purposes of this subsection 4(d)(i) and subsection 4(d)(ii): (1) The aggregate maximum number of shares of Common Stock deliverable upon exercise (assuming the satisfaction of any conditions to exercisability, including without limitation, the passage of time, but without taking into account potential antidilution adjustments) of such options to purchase or rights to subscribe for Common Stock shall be deemed to have been issued at the time such options or rights were issued and for a consideration equal to the consideration (determined in the manner provided in subsections 4(d)(i)(C) and (d)(i)(D)), if any, received by this Corporation upon the issuance of such options or rights plus the minimum exercise price provided in such options or rights (without taking into account potential antidilution adjustments) for the Common Stock covered thereby. (2) The aggregate maximum number of shares of Common Stock deliverable upon conversion of or in exchange (assuming the satisfaction of any conditions to convertibility or exchangeability, including, without limitation, the passage of time, but without taking into account potential antidilution adjustments) for any such convertible or exchangeable securities or upon the exercise of options to purchase or rights to subscribe for such convertible or exchangeable securities and subsequent conversion or exchange thereof shall be deemed to have been issued at the time such securities were issued or such options or rights were issued and for a consideration equal to the consideration, if any, -14- received by this Corporation for any such securities and related options or rights, plus the minimum additional consideration, if any, to be received by this Corporation (without taking into account potential antidilution adjustments) upon the conversion or exchange of such securities or the exercise of any related options or rights (the consideration in each case to be determined in the manner provided in subsections 4(d)(i)(C) and (d)(i)(D)). (3) In the event of any change in the number of shares of Common Stock deliverable or in the consideration payable to this Corporation upon exercise of such options or rights or upon conversion of or in exchange for such convertible or exchangeable securities, including, but not limited to, a change resulting from the antidilution provisions thereof, the Conversion Price of the Series A Preferred Stock, the Conversion Price of the Series B Preferred Stock, the Conversion Price of the Series C Preferred Stock or the Conversion Price of the Series D Preferred Stock, to the extent in any way affected by or computed using such options, rights or securities, shall be recomputed to reflect such change, but no further adjustment shall be made for the actual issuance of Common Stock or any payment of such consideration upon the exercise of any such options or rights or the conversion or exchange of such securities. (4) Upon the expiration of any such options or rights, the termination of any such rights to convert or exchange, or the expiration of any options or rights related to such convertible or exchangeable securities, the Conversion Price of the Series A Preferred Stock, the Conversion Price of the Series B Preferred Stock, the Conversion Price of the Series C Preferred Stock or the Conversion Price of the Series D Preferred Stock, to the extent in any way affected by or computed using such options, rights or securities, or options or rights related to such securities, shall be recomputed to reflect the issuance of only the number of shares of Common Stock (and convertible or exchangeable securities that remain in effect) actually issued upon the exercise of such options or rights, upon the conversion or exchange of such securities, or upon the exercise of the options or rights related to such securities. (5) The number of shares of Common Stock deemed issued and the consideration deemed paid therefor pursuant to subsections 4(d)(i)(E)(1) and (2) shall be appropriately adjusted to reflect any change, termination or expiration of the type described in either subsection 4(d)(i)(E)(3) or (4). (ii) "Additional Stock" shall mean any shares of Common Stock issued (or deemed to have been issued pursuant to subsection 4(d)(i)(E)) by this Corporation after the Purchase Date other than: -15- (A) Common Stock issued pursuant to a transaction described in subsection 4(d)(iii) hereof; (B) Common Stock issuable or issued to employees, consultants, directors or vendors (if in transactions with primarily non-financing purposes) of this Corporation directly or pursuant to a stock option plan or restricted stock plan approved by the Board of Directors and stockholders of this Corporation; (C) Common Stock issued upon conversion of shares of Preferred Stock; (D) Common Stock issued in a firm commitment underwritten public offering; (E) Common Stock, or securities convertible into Common Stock issued to banks or equipment lessors, provided such issuances are for other than primarily equity financing purposes; and (F) Common Stock issued in connection with business combinations or corporate partnering agreements approved by the Board of Directors. (iii) If this Corporation shall, after the Purchase Date, fix a record date for the effectuation of a split or subdivision of the outstanding shares of Common Stock or the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in additional shares of Common Stock or other securities or rights convertible into, or entitling the holder thereof to receive, directly or indirectly, additional shares of Common Stock (hereinafter referred to as "Common Stock Equivalents") without payment of any consideration by such holder for the additional shares of Common Stock or the Common Stock Equivalents (including the additional shares of Common Stock issuable upon conversion or exercise thereof), then, as of such record date (or the date of such dividend distribution, split or subdivision if no record date is fixed), the Conversion Price of the Series A Preferred Stock, the Conversion Price of the Series B Preferred Stock, the Conversion Price of the Series C Preferred Stock and the Conversion Price of the Series D Preferred Stock shall be appropriately decreased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be increased in proportion to such increase of the aggregate of shares of Common Stock outstanding and those issuable with respect to such Common Stock Equivalents. (iv) If the number of shares of Common Stock outstanding at any time after the Purchase Date is decreased by a combination of the outstanding shares of Common Stock, then, following the record date of such combination, the Conversion Price for the Series A Preferred Stock, the Conversion Price of the -16- Series B Preferred Stock, the Conversion Price of the Series C Preferred Stock and the Conversion Price of the Series D Preferred Stock shall be appropriately increased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be decreased in proportion to such decrease in outstanding shares. (v) Upon (A) a sale by the Corporation of its Common Stock in a transaction immediately following which its Common Stock is publicly traded, (B) the acquisition of the Corporation by another entity by means of any transaction or series of related transactions (including, without limitation, any reorganization, merger or consolidation) or (C) a sale of all or substantially all of the assets of the Corporation; provided such event shall have occurred prior to December 1, 2000 and the price per share received by the holders of the Common Stock (assuming conversion of all convertible securities and exercise of all vested options and warrants) is at least $9.00 per share (adjusted to reflect subsequent stock dividends, stock splits or recapitalizations), then the Conversion Price in effect for the Series C Preferred Stock shall be adjusted as of the effective date of such event to a price determined by multiplying such Conversion Price by 1.2069. (e) Intentionally Left Blank. (f) Recapitalizations. If at any time or from time to time there ----------------- shall be a recapitalization of the Common Stock (other than a subdivision, combination or merger or sale of assets transaction provided for elsewhere in this Section 4 or in Section 2), provision shall be made so that the holders of the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock shall thereafter be entitled to receive upon conversion thereof the number of shares of stock or other securities or property of this Corporation or otherwise to which a holder of Common Stock deliverable upon conversion would have been entitled on such recapitalization. In any such case, appropriate adjustment shall be made in the application of the provisions of this Section 4 with respect to the rights of the holders of the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock after the recapitalization to the end that the provisions of this Section 4 (including adjustment of the Conversion Price then in effect and the number of shares purchasable upon conversion of the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock) shall be applicable after that event as nearly equivalent as may be practicable. (g) No Impairment. This Corporation will not, by amendment of its ------------- Fifth Amended and Restated Certificate of Incorporation or through any reorganization, recapitalization, 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 -17- hereunder by this Corporation, but will at all times in good faith assist in the carrying out of all the provisions of this Section 4 and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of the holders of the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock against impairment. (h) No Fractional Shares and Certificate as to Adjustments. ------------------------------------------------------ (i) No fractional shares shall be issued upon the conversion of any share or shares of the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock, and the number of shares of Common Stock to be issued shall be rounded to the nearest whole share. Whether or not fractional shares are issuable upon such conversion shall be determined on the basis of the total number of shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock the holder is at the time converting into Common Stock and the number of shares of Common Stock issuable upon such aggregate conversion. (ii) Upon the occurrence of each adjustment or readjustment of the Conversion Price of Series A Preferred Stock, the Conversion Price of the Series B Preferred Stock, the Conversion Price of the Series C Preferred Stock or the Conversion Price of the Series D Preferred Stock pursuant to this Section 4, this Corporation, at its expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to each holder of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock, as applicable, a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. This Corporation shall, upon the written request at any time of any holder of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock, furnish or cause to be furnished to such holder a like certificate setting forth (A) such adjustment and readjustment, (B) the Conversion Price for such series of Preferred Stock at the time in effect, and (C) the number of shares of Common Stock and the amount, if any, of other property that at the time would be received upon the conversion of a share of such series of Preferred Stock. (i) Notices of Record Date. In the event of any taking by this ---------------------- Corporation of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend) or other distribution, any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other right, this Corporation shall mail to each holder of Series A Preferred Stock, each holder of Series B Preferred Stock, each holder of Series C Preferred Stock and each holder of Series D Preferred Stock, at least twenty (20) days prior to the date specified therein, a notice specifying the date on -18- which any such record is to be taken for the purpose of such dividend, distribution or right, and the amount and character of such dividend, distribution or right. (j) Reservation of Stock Issuable Upon Conversion. This Corporation --------------------------------------------- shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the shares of the Series A Preferred Stock, Series B Preferred Stock, the Series C Preferred Stock and the Series D Preferred Stock, such number of its shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of the Series A Preferred Stock, Series B Preferred Stock, the Series C Preferred Stock and the Series D 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 Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock, in addition to such other remedies as shall be available to the holder of such Preferred Stock, this Corporation will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes, including, without limitation, engaging in best efforts to obtain the requisite stockholder approval of any necessary amendment to this Certificate. (k) Notices. Any notice required by the provisions of this Section 4 ------- to be given to the holders of shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock shall be deemed given if deposited in the United States mail, postage prepaid, and addressed to each holder of record at his address appearing on the books of this Corporation. (l) Special Mandatory Conversion. ---------------------------- (i) If (a) this Corporation consummates a financing (the "Financing") pursuant to which the holders of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock are entitled to exercise the right of first offer (the "Right of First Offer") set forth in Section 2.4 of the Fourth Amended and Restated Investors' Rights Agreement, dated on or about January 2000, by and among this Corporation and certain investors and founders, as amended from time to time (the "Rights Agreement"); (b) the Board of Directors of this Corporation shall have determined that holders of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock of this Corporation must participate in the Financing (a "Mandatory Offering") and have determined the aggregate dollar amount to be invested by all holders of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock, which amount may be more than or less than the holders' right to participate in the Financing pursuant to the Right of First Offer contained in the Rights Agreement; (c) this Corporation shall have delivered a notice ("Notice") to the holders of Series A Preferred Stock, -19- Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock: (1) stating this Corporation's bona fide intention to consummate the Financing, (2) indicating the number of securities to be offered, (3) indicating the price and terms upon which it proposes to offer such securities, (4) identifying the Pro Rata Share (as defined below) of the Major Investor Portion to be invested by each holder of Series A Preferred Stock, each holder of Series B Preferred Stock, each holder of Series C Preferred Stock and each holder of Series D Preferred Stock, and (5) offering each holder of Series A Preferred Stock, each holder of Series B Preferred Stock, each holder of Series C Preferred Stock and each holder of Series D Preferred Stock the right to purchase such holder's Pro Rata Share of the Major Investor Portion within the time periods set forth in the Notice; and (d) a holder (a "Non-Participating Holder") does not acquire at least its Pro Rata Share within the time periods set forth in the Notice, then that percentage of each Non-Participating Holder's shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock, as applicable, equal to the percentage of such Non-Participating Holder's Pro Rata Share not acquired by such Non-Participating Holder shall automatically and without further action on the part of such holder be converted effective upon, subject to, and concurrently with, the consummation of the Mandatory Offering (the "Mandatory Offering Date") into shares of Common Stock of this Corporation at a Conversion Price equal to the applicable Original Issue Price (as adjusted for any stock dividends, combinations or splits). For purposes of this subsection 4(l), each holder's Pro Rata Share shall be an amount determined by multiplying the aggregate amount to be invested by the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock, as applicable, by a fraction, the numerator of which shall be the number of shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock, as applicable, then held by such holder and the denominator of which shall be the total number of shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock, as applicable, then outstanding. For purposes of this subsection 4(l), a holder of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock may at its option designate one or more of its affiliates to acquire all or a portion of such holder's Pro Rata Share, and so long as such holder and/or its affiliates acquires such holder's full Pro Rata Share within the time periods set forth in the Notice, such holder shall not be deemed a Non-Participating Holder.

As promptly as practicable thereafter, this Corporation shall issue and deliver to such holder, at the place designated by such holder, a certificate or certificates for the number of full shares of the Common Stock to be issued and such holder shall be deemed to -20- have become a stockholder of record of Common Stock on the Mandatory Offering Date unless the transfer books of this Corporation are closed on that date, in which event he, she or it shall be deemed to have become a stockholder of record of Common Stock on the next succeeding date on which the transfer books are open. 5.

The holder of each share of Series A Preferred ------------- Stock, the holder of each share of Series B Preferred Stock, the holder of each share of Series C Preferred Stock and the holder of each share of Series D Preferred Stock shall have the right to one vote for each share of Common Stock into which such share of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock could then be converted, and with respect to such vote, such holder shall have full voting rights and powers equal to the voting rights and powers of the holders of Common Stock, and shall be entitled, notwithstanding any provision hereof, to notice of any stockholders' meeting in accordance with the bylaws of this Corporation, and shall be entitled to vote with respect to any question upon which holders of Common Stock have the right to vote. Fractional votes shall not, however, be permitted and any fractional voting rights available on an as-converted basis (after aggregating all shares into which shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock held by each holder could be converted) shall be rounded to the nearest whole number (with one-half being rounded upward). Unless otherwise provided herein or unless otherwise required by law, the holders of the Series A Preferred Stock, the holders of the Series B Preferred Stock, the holders of the Series C Preferred Stock and the holders of the Series D Preferred Stock shall vote on all matters together with the holders of Common Stock. 6.
