SECTION 2 REGISTRATION RIGHTS 2.1 Required Registrations. (a) At any time after the Company's Initial Public Offering, the Preferred Stockholders holding in the aggregate at least thirty-five percent (35%) of the Registrable Shares then outstanding may request, in writing, that the Company effect the registration on Form S-l or Form S-2 (or any successor form) of Registrable Shares owned by such Preferred Stockholder or Preferred Stockholders. The Company shall not register any additional shares of stock of the Company on a Registration Statement at the same time as a demand registration pursuant to this Section 2.1 without the prior written consent of the Preferred Stockholders holding at least a majority of the Registrable Shares to be included in the demand registration. (b) At any time after the Company becomes eligible to file a Registration Statement on Form S-3 (or any successor form relating to secondary offerings), any Preferred Stockholder that held greater than 8,177,284 shares of Series A-l Preferred Stock immediately following closing of the Financing (each, a "Major Stockholder") may request, in writing, that the Company effect the registration on Form S-3 (or such successor form). (c) Upon receipt of any request for registration pursuant to Section 2.1 (a) or 2.1(b), the Company shall promptly give written notice of such proposed registration to all other Preferred Stockholders in accordance with Section 6.1. Such Preferred Stockholders shall have the right, by giving written notice to the Company within 30 days after the Company provides its registration notice, to elect to have included in such registration the number of Registrable Shares as such Preferred Stockholders may request in such notice of election, subject in the case of an underwritten offering to the terms of Section 2.1(d). Thereupon, the Company shall use commercially reasonable efforts to effect the registration on an appropriate Registration Statement of all Registrable Shares that the Company has been requested to so register; provided however, that in the case of a registration requested under Section 2.1(b), the Company will only be obligated to effect such registration on Form S-3 (or any successor form). (d) If the Initiating Holders intend to distribute the Registrable Shares covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to Section 2.1 (a) or 2.1(b), as the case may be, and the Company shall include such information in its written notice referred to in Section 2.1(c). In such event, (i) the 5 right of any other Preferred Stockholder to include its Registrable Shares in such registration pursuant to Section 2.1(a) or 2.1(b) shall be conditioned upon such other Preferred Stockholder's participation in such underwriting on the terms set forth herein, and (ii) all Preferred Stockholders including Registrable Shares in such registration shall enter into an underwriting agreement upon customary terms with the underwriter or underwriters managing the offering. The Company shall have the right to select the managing underwriter(s) for any underwritten offering requested pursuant to Section 2.1(a) or (b), subject to the approval of the Initiating Holders, which approval shall not be unreasonably delayed or withheld. If any Preferred Stockholder who has requested inclusion of its Registrable Shares in such registration as provided above disapproves of the terms of the underwriting, such person may elect, by written notice to the Company, to withdraw its Registrable Shares from such registration and underwriting. In an underwritten offering, if the managing underwriter advises the Company in writing that market factors require a limitation on the number of shares to be underwritten, the number of Registrable Shares to be included in the Registration Statement and underwriting shall be allocated among all Preferred Stockholders requesting registration in proportion, as nearly as practicable, to the respective number of Registrable Shares held by them on the date of the request for registration made by the Initiating Holders pursuant to Section 2.1(a) or 2.1(b), as the case may be. If any Preferred Stockholder would thus be entitled to include more Registrable Shares than such Preferred Stockholder requested to be registered, the excess shall be allocated among other requesting Preferred Stockholders pro rata in the manner described in the preceding sentence. (e) The Company shall not be required to effect more than two (2) registrations requested by the Preferred Stockholders pursuant to Section 2.1(a) above. The Company shall not be required to effect in any twelve (12) month period more than three (3) registrations requested by the Major Stockholders pursuant to Section 2.1(b) above. For purposes of this Section 2.1(e), a Registration Statement shall not be counted (i) until such time as such Registration Statement has been declared effective by the Commission (unless the Initiating Holders withdraw their request for such registration (other than as a result of information concerning the business, properties, assets or condition (financial or otherwise) of the Company which is made known to the holders of Registrable Shares after the date on which such registration was requested) and elect not to pay the Registration Expenses therefor pursuant to Section 2.5) or (ii) if (A) less than fifty percent (50%) of the total number of Registrable Shares that Preferred Stockholders have requested to be included in such Registration Statement are sold or (B) the Company or any other person registers additional shares of stock of the Company on a Registration Statement at the same time as a demand registration pursuant to this Section 2.1. (f) If at the time of any request to register Registrable Shares pursuant to this Section 2.1 the Company is engaged or has plans to engage in a registered public offering or is engaged in any other activity which, in the good faith determination of the Company's Board of Directors, would be adversely affected by the requested registration, then the Company may at its option direct that such request be delayed for a period not in excess of ninety (90) days from the effective date of such request, provided that such right to delay a request may not be exercised by the Company more than twice in any twelve month period, and the Company shall thereafter promptly file a Registration Statement and cause such Registration Statement to become effective as soon as practicable after filing. 6 2.2 Incidental Registration. (a) Whenever the Company proposes to file a Registration Statement, including a Registration Statement to effect an Initial Public Offering, at any time and from time to time, it will, prior to such filing, give written notice to all Preferred Stockholders and Warrantholders of its intention to do so. Upon the written request of one or more Preferred Stockholders or Warrantholders given within fifteen (15) days after the Company provides such notice (which request shall state the intended method of disposition of such Registrable Shares), the Company shall use commercially reasonable efforts to cause all Registrable Shares which the Company has been requested by such Preferred Stockholders and Warrantholders to be registered under the Securities Act (in the case of an Initial Public Offering, however, in an amount not to exceed 25% of all shares of Common Stock offered in such Initial Public Offering) to the extent necessary to permit their sale or other disposition in accordance with the intended methods of distribution specified in the request of such Preferred Stockholders and Warrantholders; provided that the Company shall have the right to postpone or withdraw any registration effected pursuant to this Section 2.2 without obligation to any Preferred Stockholder or Warrantholder. (b) If the registration for which the Company gives notice pursuant to Section 2.2(a) is a registered public offering involving an underwriting, the Company shall so advise the Preferred Stockholders and Warrantholders as a part of their written notice made pursuant to Section 2.2(a). In such event, (i) the right of any Preferred Stockholder or Warrantholder to include his, her or its Registrable Shares in such registration pursuant to Section 2.2 shall be conditioned upon such Preferred Stockholder's and Warrantholder's participation in such underwriting on the terms set forth herein, and (ii) all Preferred Stockholders and Warrantholders including Registrable Shares in such registration shall enter into an underwriting agreement upon customary terms with the underwriter or underwriters selected for the underwriting by the Company. If any Preferred Stockholder or Warrantholder who has requested inclusion of his, her or its Registrable Shares in such registration as provided above disapproves of the terms of the underwriting, such Preferred Stockholder or Warrantholder may elect, by written notice to the Company, to withdraw his, her or its Registrable Shares from such Registration Statement and underwriting. If the managing underwriter advises the Company in writing that market factors require a limitation on the number of shares to be underwritten, all of the shares held by holders other than the Preferred Stockholders and Warrantholders, including any officers, directors or employees of the Company, shall first be excluded from such Registration Statement and underwriting to the extent deemed advisable by the managing underwriter, and, if further reduction of the number of shares is required, the number of shares that may be included in the Registration Statement and underwriting shall be allocated among all Preferred Stockholders and Warrantholders requesting registration in proportion, as nearly as practicable, to the respective number of Registrable Shares held by them on the date the Company gives the notice specified in Section 2.2(a); provided that the number of Registrable Shares included in such registration on behalf of the Preferred Stockholders and Warrantholders requesting registration shall not be less than thirty percent (30%) of the total shares requested to be registered (except in the case of an Initial Public Offering, in which case the number of Registrable Shares included in such registration on behalf of the Preferred Stockholders and Warrantholders requesting registration shall not be less than twenty-five (25%) of the total shares registered in such offering). If any Preferred Stockholder or Warrantholder would thus be entitled to include more shares than such 7 holder requested to be registered, the excess shall be allocated among other requesting Preferred Stockholders and Warrantholders pro rata in the manner described in the preceding sentence. 2.3 Aggregation. For purposes of this Agreement, for any Preferred Stockholder, Wararntholder or Major Stockholder that is a partnership, corporation or limited liability company, the general partner, limited partners, retired partners, shareholders, members, retired members and Affiliates of such Preferred Stockholder, Warrantholder or Major Stockholder, and the general partners, limited partners, retired partners, shareholders, members, retired members or Affiliates of the foregoing, or investment vehicles for whom any of the foregoing is a general partner, manager or investment advisor, as applicable, and the estates, beneficiaries and family members of any such general partner, limited partners, retired partners, shareholders, members, and retired members and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single "Preferred Stockholder," "Warrantholder" or "Major Stockholder." The determination of whether a Preferred Stockholder is a "Major Stockholder" and the determination of any pro rata reduction pursuant to Section 2.1(d) or 2.2(b) with respect to such Preferred Stockholder shall be based upon the aggregate amount of Registrable Shares owned by all entities and individuals included in such "Preferred Stockholder" or "Major Stockholder", as defined in this section. 2.4 Registration Procedures. (a) If and whenever the Company is required by the provisions of this Agreement to use commercially reasonable efforts to effect the registration of any Registrable Shares under the Securities Act, the Company shall expeditiously: (i) prepare and file with the Commission a Registration Statement with respect to such Registrable Shares and use commercially reasonable efforts to cause that Registration Statement to become effective as promptly as practicable and to keep the Registration Statement effective for up to twelve (12) months from the effective date or such lesser period until all such Registrable Shares are sold; provided however, that such twelve month period shall be extended for a period of time equal to the period the Selling Stockholders refrain from selling any securities of the Company included in such registration at the request of an underwriter of the Company's Common Stock or as required pursuant to Section 2.4(b) and (c); (ii) prepare and file with the Commission any amendments and supplements to the Registration Statement and the Prospectus included in the Registration Statement as may be necessary to comply with the provisions of the Securities Act (including the anti-fraud provisions thereof); (iii) furnish to each Selling Stockholder such reasonable numbers of copies of the Prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as the Selling Stockholder may reasonably request in order to facilitate the public sale or other disposition of the Registrable Shares owned by such Selling Stockholder; 8 (iv) register or qualify the Registrable Shares covered by the Registration Statement under the securities or Blue Sky laws of such states as the Selling Stockholders shall reasonably request; provided however, that the Company shall not be required in connection with this subsection (iv) to qualify as a foreign corporation or execute or file a general consent to service of process in any jurisdiction, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act; (v) cause all such Registrable Shares to be listed on each securities exchange or automated quotation system on which similar securities issued by the Company are then listed; (vi) provide a transfer agent and registrar for all such Registrable Shares and a CUSIP number not later than the effective date of such Registration Statement; (vii) notify each Selling Stockholder, promptly after it shall receive notice thereof, of the time when such Registration Statement has become effective or a supplement to any Prospectus forming a part of such Registration Statement has been filed; (viii) following the effectiveness of such Registration Statement, notify each Selling Stockholder of any request by the Commission for the amending or supplementing of such Registration Statement or Prospectus; (ix) notify each Selling Stockholder of Registrable Shares covered by such Registration Statement upon the occurrence of any event as a result of which the Prospectus included in a Registration Statement, as then in effect, contains an untrue statement of material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing, and prepare, file and furnish to each such Selling Stockholder a reasonable number of copies of a supplement or an amendment to such Prospectus as may be necessary so that such Prospectus does not contain an untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing; and (x) use commercially reasonable efforts to prevent the issuance of any stop order or other order suspending the effectiveness of a Registration Statement covering Registrable Shares and, if such an order is issued, to use commercially reasonable efforts to obtain the withdrawal thereof at the earliest possible time and to notify the Selling Stockholder of the issuance of such order and the resolution thereof. (b) At the request of any Selling Stockholder at any time after any Registrable Shares held by such Selling Stockholder become eligible for resale pursuant to Rule 144(k) under the Securities Act, the Company shall deliver a letter to the Company's transfer agent irrevocably instructing the transfer agent to remove any securities law legend from any certificate representing such Registrable Shares which have become eligible for sale pursuant to Rule 144(k). (c) If the Company has delivered a Prospectus to the Selling Stockholders and after having done so the Prospectus is amended to comply with the requirements of the Securities 9 Act, the Company shall promptly notify the Selling Stockholders and, if requested, the Selling Stockholders shall immediately cease making offers of Registrable Shares and return all Prospectuses to the Company. The Company shall promptly provide the Selling Stockholders with revised Prospectuses and, following receipt of the revised Prospectuses, the Selling Stockholders shall be free to resume making offers of the Registrable Shares. (d) In the event that, in the reasonable judgment of the Company, it is advisable to suspend use of a Prospectus included in a Registration Statement due to pending material developments or other events that have not yet been publicly disclosed and as to which the Company believes public disclosure would be detrimental to the Company, the Company shall notify all Selling Stockholders to such effect, and, upon receipt of such notice, each such Selling Stockholder shall immediately discontinue any sales of Registrable Shares pursuant to such Registration Statement until such Selling Stockholder has received copies of a supplemented or amended Prospectus or until such Selling Stockholder is advised in writing by the Company that the then current Prospectus may be used and has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such Prospectus. Notwithstanding anything to the contrary herein, the Company shall not exercise its rights under this Section 2.4(c) to suspend sales of Registrable Shares for a period in excess of 60 calendar days consecutively or 180 calendar days in the aggregate in any 365-day period. 2.5 Allocation of Expenses. The Company shall pay all Registration Expenses of all registrations under this Agreement; provided however, that if a registration under Section 2.1(a) is withdrawn at the request of the Initiating Holders holding a majority of the shares requested by such Initiating Holders to be so registered and if such Initiating Holders elect not to have such registration counted as a registration requested under Section 2.1(a), the Selling Stockholders shall pay the Registration Expenses of such registration pro rata in accordance with the number of their Registrable Shares included in such registration; provided further however, that if at the time of such withdrawal, the Initiating Holders have either (i) learned material adverse information concerning the business, properties, assets or condition (financial or otherwise) of the Company which is made known to the Selling Stockholders after the date on which such registration was requested and materially impacts the Offering or (ii) been informed by the underwriters of such registration that more than twenty-five percent (25%) of the Registrable Shares requested for registration shall not be included therein due to market factors, and in either such case the Initiating Holders have withdrawn the request with reasonable promptness following such disclosure, then the Selling Stockholders shall not be required to pay the Registration Expenses and shall retain all of their rights, including their demand and incidental registration rights pursuant to Sections 2.1 and 2.2. 2.6 Indemnification and Contribution. (a) In the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, the Company will indemnify and hold harmless each Selling Stockholder, each underwriter of such Registrable Shares, and each other person, if any, who controls such Selling Stockholder or underwriter within the meaning of the Securities Act or the Exchange Act against any losses, claims, damages or liabilities, joint or several, to which such Selling Stockholder, underwriter or controlling person may become subject under the 10 Securities Act, the Exchange Act, state securities or Blue Sky laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement under which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained in the Registration Statement, or any amendment or supplement to such Registration Statement, (ii) the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law in connection with the Registration Statement or the offering contemplated thereby; and the Company will reimburse such Selling Stockholder, underwriter and each such controlling person for any legal or any other expenses reasonably incurred by such Selling Stockholder, underwriter or controlling person in connection with investigating or defending any such loss, claim, damage, liability or action; provided however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any untrue statement or omission made in such Registration Statement, preliminary prospectus or final prospectus, or any such amendment or supplement, in reliance upon and in conformity with information furnished to the Company, in writing, by or on behalf of such Selling Stockholder, underwriter or controlling person specifically for use in the preparation thereof. (b) In the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, each Selling Stockholder, severally and not jointly, will indemnify and hold harmless the Company, each of its directors and officers and each underwriter (if any) and each person, if any, who controls the Company or any such underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages or liabilities, joint or several, to which the Company, such directors and officers, underwriter or controlling person may become subject under the Securities Act, Exchange Act, state securities or Blue Sky laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement under which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained in the Registration Statement, or any amendment or supplement to the Registration Statement, or (ii) any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, if and to the extent (and only to the extent) that the statement or omission was made solely in reliance upon and in conformity with information relating to such Selling Stockholder furnished in writing to the Company by or on behalf of such Selling Stockholder specifically for use in connection with the preparation of such Registration Statement, prospectus, amendment or supplement; provided however, that the obligations of each such Selling Stockholder hereunder shall be limited to an amount equal to the net proceeds received by such Selling Stockholder of Registrable Shares sold in connection with such registration. (c) Each Indemnified Party shall give notice to the Indemnifying Party promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided, that counsel for the Indemnifying Party, who 11 shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld, conditioned or delayed); and, provided further, that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 2.6 except to the extent that the Indemnifying Party is adversely affected by such failure. The Indemnified Party may participate in such defense at such party's expense; provided however, that the Indemnifying Party shall pay such expense if representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to actual or potential differing interests between the Indemnified Party and any other party represented by such counsel in such proceeding; provided further, that in no event shall the Indemnifying Party be required to pay the expenses of more than one law firm per jurisdiction as counsel for the Indemnified Party. The Indemnifying Party shall also be responsible for the expenses of such defense if the Indemnifying Party does not elect to assume such defense. No Indemnifying Party, in the defense of any such claim or litigation shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect of such claim or litigation, and no Indemnified Party shall consent to entry of any judgment or settle such claim or litigation without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed. (d) An underwriter shall not be entitled to indemnification pursuant to this Section 2.6 in the event that it fails to deliver to any Selling Stockholder any preliminary or final or revised Prospectus, as required by the rules and regulations of the Commission. (e) In order to provide for just and equitable contribution to joint liability under the Securities Act in circumstances in which the indemnification provided for in this Section 2.6 is due in accordance with its terms but for any reason is held to be unavailable to an Indemnified Party in respect to any losses, claims, damages and liabilities referred to herein, then the Indemnifying Party shall, in lieu of indemnifying such Indemnified Party, contribute to the amount paid or payable by such Indemnified Party as a result of losses, claims, damages or liabilities to which such party may be subject in such proportions as is appropriate to reflect the relative fault of the Company on the one hand and the Selling Stockholders on the other in connection with the statements, omissions or violations which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Company and the Selling Stockholders shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of material fact related to information supplied by the Company or the Selling Stockholders and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Selling Stockholders agree that it would not be just and equitable if contribution pursuant to this Section 2.6(e) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this Section 2.6(e), (i) in no case shall any one Selling Stockholder be liable or responsible for any amount in excess of the net proceeds received by such Selling Stockholder from the offering of Registrable Shares and (ii) the Company shall be liable and responsible for at least any amount in excess of such proceeds; provided however that no person guilty of fraudulent misrepresentation (within the meaning of 12 Section 11(f) of the Securities Act) shall be entitled to contribution from any person or entity who is not guilty of such fraudulent misrepresentation. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section 2.6(e), notify such party or parties from whom contribution may be sought, but the omission so to notify such party or parties from whom contribution may be sought shall not relieve such party from any other obligation it or they may have thereunder or otherwise under this Section 2.6(e). No party shall be liable for contribution with respect to any action, suit, proceeding or claim settled without its prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed. (f) The rights and obligations of the Company and the Selling Stockholders under this Section 2.6 shall survive the termination of this Agreement. 2.7 Other Matters with Respect to Underwritten Offering. In the event that Registrable Shares are sold pursuant to a Registration Statement in an underwritten offering pursuant to Section 2.1, the Company agrees to (a) enter into an underwriting agreement containing customary representations and warranties with respect to the business and operations of an issuer of the securities being registered and customary covenants and agreements to be performed by the Company, including without limitation customary provisions with respect to indemnification by the Company of the underwriters of such offering; (b) use commercially reasonable efforts to cause its legal counsel to render customary opinions to the underwriters with respect to the Registration Statement; and (c) use commercially reasonable efforts to cause its independent public accounting firm to issue customary "cold comfort letters" to the underwriters with respect to the Registration Statement. 2.8 Information by Holder. Each Selling Stockholder shall furnish to the Company such information regarding such holder and the distribution proposed by such holder as the Company may reasonably request in writing and as shall be required in connection with any registration, qualification or compliance referred to in this Agreement. 2.9 Market "Stand-Off" Agreement. Each Preferred Stockholder and Warrantholder, if requested by the Company and the managing underwriter of an underwritten public offering by the Company of Common Stock, shall not sell or otherwise transfer or dispose of any Registrable Shares or other securities of the Company (excluding securities acquired in the Initial Public Offering or in the public market after such offering) held by such Preferred Stockholder and Warrantholder for a period specified by the managing underwriter of an underwritten public offering by the Company, which period shall not exceed 180 days following the effective date of a Registration Statement of the Company filed under the Securities Act; provided that, (a) such agreement shall only apply to the Initial Public Offering of the Company, (b) such agreement shall not apply to any Registrable Securities included in the Initial Public Offering of the Company pursuant to the terms hereof and (c) all stockholders of the Company then holding at least 1% of the outstanding shares of Common Stock (on an as-converted basis) and all officers and directors of the Company enter into similar agreements. Any discretionary waiver or termination of the restrictions of such agreements (including this Agreement) by the Company or the managing underwriter shall apply to all persons subject to such agreements on a pro rata basis, based upon the number of shares held by such persons. Each Preferred Stockholder and 13 Warrantholder agrees to execute and deliver such other agreements as may be reasonably requested by the Company and/or the managing underwriter(s) which are consistent with the foregoing or which are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to such Capital Stock subject to the foregoing restriction until the end of such lock-up period. The underwriters of any class of the Company's capital stock are intended third party beneficiaries of this Section 2.9 and shall have the right, power and authority to enforce the provisions hereof as though they were parties hereto. 2.10 Limitations on Subsequent Registration Rights. Except with respect to assignees as contemplated by Section 5 hereof, the Company shall not, without the prior written consent of Preferred Stockholders holding at least sixty percent (60%) of the Registrable Shares, enter into any agreement with any holder or prospective holder of any securities of the Company which would allow such holder or prospective holder to include securities of the Company in any Registration Statement. 2.11 Rule 144 Requirements. After the earliest of (i) the closing of the sale of securities of the Company pursuant to a Registration Statement, (ii) the registration by the Company of a class of securities under Section 12 of the Exchange Act, or (iii) the issuance by the Company of an offering circular pursuant to Regulation A under the Securities Act, the Company agrees to: (a) comply with the requirements of Rule 144(c) under the Securities Act with respect to current public information about the Company; (b) file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements); and (c) furnish to any holder of Registrable Shares upon request (i) a written statement by the Company as to its compliance with the requirements of said Rule 144(c), and the reporting requirements of the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), (ii) a copy of the most recent annual or quarterly report of the Company, and (iii) such other reports and documents of the Company as such holder may reasonably request to avail itself of any similar rule or regulation of the Commission allowing it to sell any such securities without registration. 2.12 Company Sale. The Company shall not, directly or indirectly, enter into any Company Sale in which the Company shall not be the surviving corporation unless the proposed surviving corporation shall, prior to such Company Sale, agree in writing to assume the obligations of the Company under this Agreement, and for that purpose references hereunder to "Registrable Shares" shall be deemed to be references to the securities which the Preferred Stockholders would be entitled to receive in exchange for Registrable Shares under any such Company Sale; provided however, that (i) the provisions of this Section 2.12 may be waived by the holders of at least sixty percent (60%) of the then outstanding Registrable Securities and (ii) the provisions of this Section 2.12 shall not apply in the event of any Company Sale in which the Company is not the surviving corporation if all Preferred Stockholders are entitled to receive in 14 exchange for their Registrable Shares consideration consisting solely of (i) cash, (ii) securities of the acquiring corporation which may be immediately sold to the public without registration under the Securities Act, or (iii) securities of the acquiring corporation which the acquiring corporation has agreed to use its best efforts to register within 90 days of completion of the transaction for resale to the public pursuant to the Securities Act. 2.13 Termination. All of the Company's obligations to register Registrable Shares under this Agreement shall terminate on the earlier of (i) the seventh year anniversary of the consummation of the Initial Public Offering or (ii) the date on which no Preferred Stockholder or Warrantholder holds any Registrable Shares. SECTION 3 PARTICIPATION RIGHTS 3.1 Participation Rights. (a) The Company shall not issue, sell or exchange, agree to issue, sell or exchange, or reserve or set aside for issuance, sale or exchange, any Offered Securities (excluding those described in Section 3.1(h)), unless in each such case the Company shall have first complied with this Section 3.1. The Company shall deliver to each Major Stockholder an Offer, which shall (i) identify and describe the Offered Securities, (ii) describe the price and other terms upon which they are to be issued, sold or exchanged, and the number or amount of the Offered Securities to be issued, sold or exchanged, (iii) identify the persons or entities to which or with which the Offered Securities are to be offered, issued, sold or exchanged and (iv) offer to issue and sell to or exchange with such Major Stockholder such Major Stockholder's Basic Amount and Undersubscription Amount. Each Major Stockholder shall have the right, for a period of fifteen (15) days following delivery of the Offer, to purchase or acquire, at a price and upon the other terms specified in the Offer, up to the number or amount of the Offered Securities described above. The Offer by its terms shall remain open and irrevocable for such 15-day period. (b) To accept an Offer, in whole or in part, a Major Stockholder must deliver a Notice of Acceptance to the Company prior to the end of the 15-day period of the Offer, setting forth the portion of the Major Stockholder's Basic Amount that such Major Stockholder elects to purchase and, if such Major Stockholder shall elect to purchase all of its Basic Amount, the Undersubscription Amount (if any) that such Major Stockholder elects to purchase. If the Basic Amounts subscribed for by all Major Stockholders are less than the total of all Basic Amounts available for purchase, then each Major Stockholder who has set forth Undersubscription Amounts in its Notice of Acceptance shall be entitled to purchase, in addition to the Basic Amounts subscribed for, the Undersubscription Amount it has subscribed for; provided however, that should the Undersubscription Amounts subscribed for exceed the Available Undersubscription Amount, each Major Stockholder who has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription Amount as the Undersubscription Amount subscribed for by such Major Stockholder bears to the total Undersubscription Amounts subscribed for by all Major 15 Stockholders, subject to rounding by the Board of Directors to the extent it reasonably deems necessary. (c) The Company shall have 90 days from the expiration of the 15-day period set forth in Section 3.1 (a) above to issue, sell or exchange all or any part of the Refused Securities, but only to the offerees or purchasers described in the Offer and only upon terms and conditions (including, without limitation, unit prices and interest rates) which are not more favorable, in the aggregate, to the acquiring person or persons or less favorable, in the aggregate, to the Company than those set forth in the Offer. (d) In the event the Company shall propose to sell less than all the Refused Securities (any such sale to be in the manner and on the terms specified in Section 3.1(c) above), then each Major Stockholder may, at his, her or its sole option and in his, her or its sole discretion, reduce the number or amount of the Offered Securities specified in his, her or its Notice of Acceptance to an amount that shall be not less than the number or amount of the Offered Securities that the Major Stockholder elected to purchase pursuant to Section 3.1(b) above multiplied by a fraction, (i) the numerator of which shall be the number or amount of Offered Securities the Company actually proposes to issue, sell or exchange (including Offered Securities to be issued or sold to Major Stockholders pursuant to Section 3.1(b) above prior to such reduction) and (ii) the denominator of which shall be the original amount of the Offered Securities. In the event that any Major Stockholder so elects to reduce the number or amount of Offered Securities specified in his, her or its Notice of Acceptance, the Company may not issue, sell or exchange more than the reduced number or amount of the Offered Securities unless and until such securities have again been offered to the Major Stockholders in accordance with Section 3.1(a) above. (e) Upon the closing of the issuance, sale or exchange of all of the Refused Securities or less than all, in accordance with Section 3.1(d), of the Refused Securities, the Major Stockholders shall acquire from the Company, and the Company shall issue to the Major Stockholders, the number or amount of Offered Securities specified in the Notices of Acceptance, as reduced pursuant to Section 3.1(d) above if the Major Stockholders have so elected, upon the terms and conditions specified in the Offer. (f) The purchase by the Major Stockholders of any Offered Securities is subject in all cases to the preparation, execution and delivery by the Company and the Major Stockholders of a purchase agreement relating to such Offered Securities reasonably satisfactory in form and substance to the Company, the Major Stockholders and their respective counsel. (g) Any Offered Securities not acquired by the Major Stockholders or other persons in accordance with Section 3.1(c) above may not be issued, sold or exchanged until they are again offered to the Major Stockholders under the procedures specified in this Agreement. (h) The rights of the Major Stockholder under this Section 3 shall not apply to: (i) shares of Series A-l Preferred Stock issued pursuant to the Purchase Agreement; 16 (ii) shares of Common Stock issuable upon conversion of shares of Series A-l Preferred Stock; (iii) shares of Common Stock issued upon conversion of any debenture, warrant, option or other convertible security that is outstanding on the date of this Agreement (including up to 5,119,139 shares of Common Stock (as may be adjusted in the event of any stock dividend, stock split, combination or other similar recapitalization affecting shares of Common Stock) issued upon exercise of warrants granted in connection with certain credit facilities on the date of this Agreement); (iv) shares of Common Stock issued as a dividend or distribution on the Series A-l Preferred Stock; (v) shares of Common Stock issued or deemed issued by reason of a dividend, stock split, split-up or other distribution on shares of Common Stock; (vi) up to an aggregate of 15,204,427 shares of Common Stock (or options or other rights with respect thereto, including shares of Common Stock issuable upon exercise thereof) (subject in either case to appropriate adjustment for any stock dividend, stock split, combination or similar recapitalization affecting such shares), issued to employees or directors of, or consultants to, the Company or any of its subsidiaries pursuant to a plan, agreement or arrangement approved by a majority of the members of the Board of Directors of the Corporation; (vii) up to an aggregate of 5,000,000 shares of Common Stock (subject to appropriate adjustment for any stock dividend, stock split, combination or similar recapitalization affecting such shares), issued in connection with the Company's acquisition of any business or assets used in a business; (viii) up to 35,437 shares of Series A-l Preferred Stock (as may be adjusted in the event of any stock, dividend, stock split, combination or similar recapitalization affecting shares of Series A-l Preferred Stock) issued to Silicon Valley Bank; (ix) up to 6,600,000 shares of Series A-l Preferred Stock to be issued in connection with a merger or acquisition of product(s) approved by the holders of at least sixty percent (60%) of the then outstanding shares of Series A-l Preferred Stock; and (x) shares of Common Stock issued in a Qualified Public Offering. 3.2 Directed Shares. In the event that an Initial Public Offering is consummated at least one year after the closing of the Financing, the Company will use its reasonable best efforts to cause the managing underwriter(s) of such Initial Public Offering to designate a number of shares equal to ten percent (10%) of the Company's shares of Common Stock to be offered in such Initial Public Offering for sale under a "directed shares program" and shall instruct such underwriter(s) to allocate no less than fifty percent (50%) of such directed shares program to be sold to persons or entities designated by the Major Stockholders on a pro rata basis (based upon the number of Registrable Shares each Major Stockholder holds relative to the number of Registrable Shares held by all Major Stockholders). The shares designated by the underwriter(s) 17 for sale under a directed shares program are referred to herein as "directed shares." The Major Stockholders acknowledge that, despite the Company's use of its reasonable best efforts, the underwriter(s) may determine in their sole discretion that it is not advisable to designate all such shares as directed shares in the Initial Public Offering, in which case the number of designated shares may be reduced or no directed shares may be designated, as applicable; provided that such determination by such underwriter shall be made in writing and furnished to the Major Stockholders. The Major Stockholders also acknowledge that notwithstanding the terms of this Agreement, the sale of any directed shares to any person or entity pursuant to this Agreement will only be made in compliance with Rule 2110 of the National Association of Securities Dealers, Inc. Conduct Rules and federal, state and local laws, rules and regulations and only if the Initial Public Offering is consummated after one year from the date hereof. 3.3 Termination. Sections 3.1 and 3.2 hereof shall terminate upon the earlier of the closing of a Company Sale or immediately following the consummation of the Initial Public Offering.

All transfer, excise or other taxes payable to any jurisdiction (in the United States and outside of the United States) and/or by reason of the sale or issuance of the shares of Series A-l Preferred Stock (except for such taxes payable by reason of any subsequent transfer of the shares of Series A-l Preferred Stock) shall be paid or provided for by the Company.

The Company and each Subsidiary will continue to engage principally in the businesses they conduct as of the date hereof. The Company shall, and shall cause each Subsidiary to, secure, preserve and maintain all Company Intellectual Property Rights (as defined in the Purchase Agreement) owned or possessed by it, except where the failure to so secure, preserve and maintain such Intellectual Property Rights would not have a material adverse effect on the business, properties, assets or condition (financial or otherwise) of the Company or its Subsidiaries.

The Company shall, at any time during normal business hours and upon reasonable prior notice to the Company, permit any Major Stockholder, or the designated representative or agent of Major Stockholder, to (i) visit and inspect the premises and any of the properties of the Company and any Subsidiary, including its records and books of account (and make copies thereof and take extracts therefrom), and (ii) discuss the affairs, finances and accounts of the Company and any Subsidiary with its officers, directors, employees and accountants, all at the expense of such Major Stockholder; provided, that, the Company shall not be obligated under this Section 4.1(f) with respect to information that the Board of Directors determines in good faith is confidential and should not be disclosed. 19 (g) Compliance with Laws. The Company and each Subsidiary shall comply with the requirements of all applicable laws, rules, regulations and orders of the United States or any applicable foreign jurisdiction, including of the Food and Drug Administration or similar foreign governmental authority, in the conduct of its business, except where noncompliance would not have a material adverse effect on the business, properties, assets or condition (financial or otherwise) of the Company or its Subsidiaries.

The Company will also promptly notify its Board of Directors of any facts which, if such facts had existed as of the date hereof, would have constituted a material breach of any representation or warranty contained in the Purchase Agreement and has had or would reasonably be expected to have a material adverse effect on the business, properties, assets or condition (financial or otherwise) of the Company or its Subsidiaries. The Company will also promptly provide to its Board of Directors written notice and copies of any material notices or correspondence from the Food and Drug Administration or any foreign regulatory equivalent. (i) Confidentiality, Assignment of Inventions, Non-Competition and Non-Solicitation Agreements.

(m) Vesting of Stock. Unless otherwise approved by a majority of the members of the Board of Directors of the Company or a duly appointed committee thereof, all stock options and other stock equivalents issued after the date of this Agreement to employees, directors, consultants and other service providers pursuant to a stock purchase or option plan or other employee stock incentive program shall be subject to a minimum vesting schedule of at least four years, with 25% of the shares subject thereto vesting one year after the date of the issuance or grant of such shares, and the balance of such shares vesting no more frequently than monthly for three years thereafter, and shall provide for termination of vesting upon cessation of employment.

The Company will, upon any increase in the number of shares of Common Stock issuable upon conversion of the outstanding shares of Series A-l Preferred Stock, reserve additional shares of Common Stock for issuance upon such conversion, so that the number of shares of Common Stock so reserved will not at any time be less than the number of such shares issuable upon such conversion. (p) Affiliated Transactions. All transactions by and between the Company or its Subsidiaries and any officer, employee or stockholder of the Company or its Subsidiaries or persons controlled by or affiliated with such officer, employee or stockholder, shall be conducted on an arms-length basis and shall be approved by a majority of the members of the Board of Directors of the Company after full disclosure of the terms thereof. 4.2 Negative Covenants.
