Any underwriting discounts and selling commissions in connection with a registration that the Company is not obligated to pay pursuant to this Agreement shall be borne pro rata among the selling Holders.

9. Underwriting Requirements; Priorities.

(a) The Holders of a majority of the Registrable Securities included in any registration under Sections 2 or 4 will have the right to select the investment banker(s) and manager(s) to administer the offering, if any, subject to the approval of the Company, which will not be unreasonably withheld. The Company will not include in any registration under Sections 2 or 4 any securities that are not Registrable Securities without the written consent of the Holders of at least seventy-five percent (75%) of the Registrable Securities requesting such registration. If other securities are permitted to be included in a registration under Sections 2 and 4 that is an underwritten offering and the managing underwriters advise the Company that in their opinion the number of Registrable Securities and other securities requested to be included exceeds the number of Registrable Securities and other securities that can be sold at the desired price in such offering, the Company will include in such registration (i) first, prior to the inclusion of any securities that are not Registrable Securities, the number of Registrable Securities requested to be included which in the opinion of such underwriters can be sold, pro rata among the respective Holders participating in the registration on the basis of the amount of Registrable Securities owned and (ii) second, all other securities permitted to be included in such registration.

(b) The Company will have the right to select the investment banker(s) and manager(s) to administer any offering to which Section 3 is applicable,

subject to the approval of the Holders of at least seventy-five percent (75%) of the Registrable Securities included in such registration, which approval will not be unreasonably withheld. If a registration under Section 3 is an underwritten primary registration on behalf of the Company, and the managing underwriters advise the Company that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold at the desired price in such offering, the Company will include in such registration (i) first, the securities the Company proposes to sell, (ii) second, the Registrable Securities requested to be included in such registration by the Holders pro rata among the Holders thereof on the basis of the number of shares requested to be registered, and (iii) third, all other securities requested to be included in such registration; provided however, that in no event shall the number of Registrable Securities of the Holders included in the registration be reduced below thirty three and a third percent (33 1/3%) of the total amount of the securities included in such registration, unless such offering is the Initial Offering of the Company’s securities, in which case the Registrable Securities of the Holders may be excluded entirely if the underwriters make the determination described above and no other stockholder’s securities are included. If a registration under Section 3 is an underwritten secondary registration on behalf of holders of securities of the Company and the managing underwriters advise the Company that in their opinion the number of securities requested to be included in such registration exceeds the number that can be sold at the desired price in such offering, the Company will include in such registration (i) first, the securities requested to be included therein by the Holders requesting such registration and by other holders of Company securities with contractual registration rights, pro rata among the holders of such securities on the basis of the number of shares as requested to be included therein (provided that at least fifty percent (50%) of Registrable Securities requested to be included in such registration can be so included), and (ii) second, other securities requested to be included in such registration. If under clause (i) of the foregoing sentence, at least fifty percent (50%) of the Registrable Securities requested to be included in such registration cannot be so included, no securities other than Registrable Securities may be included in such registration.

(c) No person may participate in any underwritten registration hereunder unless such person (i) agrees to sell such person’s securities on the basis provided in any underwriting arrangements containing reasonable and customary terms for transactions of that type and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the term of such underwriting arrangements.

(d) If any Holder of Registrable Securities, or a holder of other securities entitled (upon request) to included in such Registration, disapproves of the terms of the underwriting, such person may elect to withdraw therefrom by written notice to the Company, the underwriter and initiating Holders delivered at least seven (7) days prior to the effective date of the registration statement. The securities so withdrawn shall also be withdrawn from the registration statement.

10. Termination of the Company’s Obligations.

(a) The Company shall have no further obligations pursuant to Section 2 with respect to any request or requests made by any Holder after the Company has, at the demand of the Holders pursuant to Section 2, effected two (2) registrations statements in which registration statements have remained effective for at least two hundred seventy (270) days or have become effective and all Registrable Securities included in such registration statement have been sold pursuant thereto.

(b) The Company shall have no obligation to effect more than two registrations in any twelve-month period pursuant to Section 4.

(c) The Company shall have no further obligation to register shares pursuant to this Agreement as to any Holder, at such earlier time at which all Registrable Securities held by such Holder (and any affiliate of the Holder with whom such Holder must aggregate its sales under Rule 144) can be sold in any three (3) month period without registration in compliance with Rule 144 of the Act.

11. Reports Under the 1934 Act. With a view to making available to the Holders the benefits of Rule 144 promulgated under the Act and any other rule or regulation of the Commission that may at any time permit a Holder to sell securities of the Company to the public without registration, the Company shall:

(a) make and keep public information available, as those terms are understood and defined in Rule 144, at all times subsequent to ninety (90) days after the effective date of the first registration statement covering a public offering filed under the Act by the Company;

(b) file with the Commission in a timely manner all reports and other documents required of the Company under the Act and the 1934 Act at any time after it is subject to such registration requirements, and take any action, including the voluntary registration of its Common Stock under Section 12 of the 1934 Act, as is necessary to enable the Holders to utilize Form S-3 for sale of their Registrable Securities; and

(c) furnish to any Holder at the Company’s expense so long as such Holder owns any of the Registrable Securities forthwith upon request a written statement by the Company that it has complied with the reporting requirements of Rule 144 (at any time after ninety (90) days after the effective date of said first registration statement filed by the Company), and of the Act and the 1934 Act (at any time after it has become subject to such reporting requirements), a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed by the Company as may be reasonably requested by any Holder in availing any Holder of any rule or regulation of the Commission permitting the selling of any such securities without registration or pursuant to Form S-3.

12. Lockup Agreement.

(a) Each Holder hereby agrees that it will not, without the prior written consent of the managing underwriter, during the period commencing on the date of the final prospectus relating to the Company’s initial public offering and ending on the date specified by the Company and the managing underwriter (such period not to exceed one hundred eighty (180) days) (i) lend, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (whether such shares or any such securities are then owned by the Holder or are thereafter acquired), or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing provisions of this Section 12 shall apply only to the Company’s Initial Offering of equity securities, shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement and shall only be applicable to the Holders if all officers, directors and greater than one percent (1%) stockholders of the Company enter into similar agreements. The underwriters in connection with the Company’s Initial Offering are intended third party beneficiaries of this Section 12 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to the Registrable Securities of each Holder (and the shares or securities of every other person subject to the foregoing restriction) until the end of such period.

(b) The Company agrees (i) not to effect any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities, during the seven (7) days prior to and during the one hundred eighty (180) day period beginning on the effective date of the final prospectus related to an underwritten offering pursuant to which Registrable Securities are to be sold under Sections 2 or 4 hereof (except a registration relating solely to a transaction under Rule 145 under the Act (or any successor thereto) or an employee benefit plan of the Company on Form S-8 (or any successor thereto)), unless the underwriters managing the registered public offering and the Holders of a majority of the Registrable Securities then outstanding otherwise agree in writing, and (ii) to use best efforts to cause each holder of at least two percent (2%) (on a fully diluted basis) of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities, purchased from the Company at any time after the date of this Agreement (other than in a registered public offering) to agree not to effect any sale or distribution of any such securities during such period (except as part of such underwritten registration, or a registration under this Agreement if otherwise permitted), unless the underwriters managing the registered public offering and the Holders of a majority of the Registrable Securities then outstanding otherwise agree.

(c) If the Company or the underwriter of any public offering of the Company’s securities waives or terminates any standoff or lockup restrictions imposed on any holder of securities of the Company, then such waiver or termination shall be granted to all Holders subject to standoff or lockup restrictions pro rata based on the number of shares of Common Stock beneficially held by or issuable to such holders. From and after the date of this Agreement, the Company shall use its best efforts to ensure that all holders of the capital stock of the Company agree to be bound by terms substantially similar to this Section 12.

13. Certain Limitations in Connection with Future Grants of Registration Rights.

(a) From and after the date of this Agreement, the Company shall not enter into any agreement with any holder or prospective holder of any securities of the Company providing for the granting to such holder of registration rights unless such agreement:

(i) includes the equivalent of Section 12 of this Agreement as a term; and

(ii) does not contain rights that are more favorable than the rights granted to the Holders of Registrable Securities in this Agreement, including without limitation, with respect to, a limitation on the number of securities to be included in an underwriting.

(b) In addition to the foregoing, the Company shall not without the written consent of the Holders of at least 66% of the outstanding Series C Preferred Stock and Series D Preferred Stock, voting together as a class on an as-if converted basis (or Common Stock issued or issuable upon conversion thereof), subsequently grant any holder of the Company’s securities any registration rights, including “demand registration rights” or “piggy-back registration rights” that are senior to or on parity with the rights granted to Holders in this Agreement.

14. Transfer of Registration Rights. Provided that the Company is given written notice by the Holder at the time of such transfer or promptly thereafter stating the name and address of the transferee and identifying the securities with respect to which the rights under this Agreement are being assigned, the registration rights under this Agreement may be transferred in whole or in part at any time, provided that the Holder is transferring at least 20% of the Registrable Securities held as of the date hereof. Notwithstanding the foregoing, a Holder may transfer and assign the rights under this agreement to a partner, retired partner, member, shareholder or affiliate of the Holder (including spouses, ancestors, lineal descendants and siblings of such partners, members, shareholders or affiliates who acquire Registrable Securities by gift, will or intestate succession) without limitation. As a condition to the transfer, the transferee must sign a

counterpart signature page whereby the transferee consents to be bound by the terms and provisions of this Agreement.

15. Indemnification. In the event any Registrable Securities are included in a registration statement under this Agreement:

(a) To the full extent permitted by law, the Company will, and hereby agrees to indemnify, defend and hold harmless each Holder requesting or joining in a registration, each director, officer, partner, member, employee, agent for or assignee of such Holder, any underwriter (as defined in the Act) for such Holder, and each person, if any, who controls such Holder or underwriter within the meaning of the Act, against all expenses, losses, claims, damages or liabilities (or actions in respect thereof), joint or several (including without limitation any of the foregoing incurred in settlement of any litigation) directly or indirectly arising out of, relating to or based on (i) any untrue or alleged untrue statement of any material fact contained in any registration statement, preliminary prospectus, final prospectus, offering, circular or other document, or any amendments or supplements thereto, (ii) any omission or alleged omission to state therein a material fact required to be stated therein in light of the circumstances under which they were made or necessary to make the statements therein not misleading, (iii) any violation by the Company of any rule or regulation promulgated under the Act applicable to the Company, or (iv) any action or inaction taken or omitted to be taken by the Company in connection with any such registration, qualification or compliance; and will reimburse each such person or entity for any legal or other expenses reasonably incurred by them in connection with investigating, preparing or defending any such loss, claim, damage, liability or action, provided, however, that the Company shall not be liable for amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the prior or subsequent consent of the Company (which consent shall not be unreasonably withheld or delayed) and the Company shall not be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in connection with such registration statement, preliminary prospectus, final prospectus, or amendments or supplements thereto, in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by or on behalf of such Holder or underwriter and stated to be expressly for use in connection with such registration.

(b) To the full extent permitted by law, each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration is being effected pursuant to this Agreement, severally, and not jointly, indemnify and hold harmless the Company, each of its directors, each of its officers who have signed the registration statement, each person, if any, who controls the Company within the meaning of the Act, each underwriter, if any, each other selling Holder, each of its officers, directors and constituent partners, and each person, if any, who controls such other selling Holder within the meaning of Section 15 of the Act against all losses, expenses, claims, damages or liabilities (or actions in respect thereof) arising out of, relating to or based on any untrue statement or alleged untrue statement of any material

fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in such registration statement, preliminary or final prospectus, or amendments or supplements thereto, in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by or on behalf of such Holder and stated to be expressly for use in connection with such registration; and each such Holder will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, controlling person or underwriter in connection with investigating or defending any such loss, claim, damage, liability or action, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in such registration statement, preliminary or final prospectus, or amendments or supplements thereto, in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by or on behalf of such Holder and stated to be expressly for use in connection with such registration; provided, however, that the indemnity agreement contained in this Section 15(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the prior or subsequent consent of such Holder (which consent shall not be unreasonably withheld or delayed).

Notwithstanding anything to the contrary, in no event shall the liability of any selling Holder of Registrable Securities hereunder be greater than the dollar amount of the net proceeds actually received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation.

(c) Promptly after receipt by an indemnified party under this Section 15 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 15, notify the indemnifying party in writing of the commencement thereof. The indemnifying party shall have the right to participate in and to assume the defense of such claim, jointly with any other indemnifying party similarly noticed, with counsel mutually satisfactory to the parties; provided, however, if the indemnified party believes representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding, the indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel (together with local counsel), with the fees and expenses to be paid by the indemnifying party. The failure to notify an indemnifying party promptly of the commencement of any such action shall not relieve the indemnifying party of its obligations under this Section 15, except to the extent, but only to the extent, that the indemnifying party is actually and materially prejudiced by such failure to give notice. 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 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 complete release from all liability in respect to such claim or litigation.

(d) If the indemnification provided for in this Section 15 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage or expense referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage or expense, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission. The parties agree that it would not be just and equitable if contributions pursuant to this Section 15(d) were to be determined pro rata or per capita allocation or by any other method that does not take account of the equitable considerations set forth above. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this Section 15(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this Section 15(d). No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Except for the Company, the amount of such contribution shall not exceed an amount equal to the net proceeds before expenses and commissions actually received by such indemnifying party from the sale of securities in the offering to which the losses, claims, damages or liabilities of the indemnified parties relate.

(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control to the extent the indemnifying party has executed such underwriting agreement.

(f) The obligations of the Company and Holders under this Section 15 shall be a continuing right to indemnification and contribution and shall survive the completion of any offering of Registrable Securities in a registration statement under this Agreement, the expiration, modification or termination of this Agreement, and otherwise.

16. Delay of Registration. Neither the Company nor any Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Agreement.

17. Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given without the prior written consent of (a) the Company, (b) the holders of at least a majority of the Registrable Securities held by all of the Holders and (c) the holders of 66% of the outstanding Series C Preferred Stock and Series D Preferred Stock, voting together as a class on an as-if converted basis; provided, however, that in the event such amendment, modification, supplement or waiver directly and adversely affects the rights and/or obligations of a Holder in a different manner than all other Holders, such amendment, modification, supplement or waiver shall also require the written consent of such adversely affected Holder, and provided further that any such amendment that lowers an approval threshold required for some act by Holders or holders of Series C Preferred Stock and Series D Preferred Stock shall require written consent of Holders or holders of Series C Preferred Stock and Series D Preferred Stock, as applicable, at least a high as the original threshold. Any such amendment, termination or waiver effected in accordance with this Section 17 shall be binding on all parties hereto, even if they do not execute such consent. No waivers of or exceptions to any term, condition or provision of this Agreement, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition or provision.

18. Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, registered or certified first-class mail, or courier guaranteeing overnight delivery:

(a) if to a Holder of Registrable Securities, at the most current address given by such Holder to the Company in accordance with the provisions of this Section 18, which address initially is, with respect to the Investors, the address set forth on the Exhibits A and B hereto.

(b) if to the Company, at its address set forth on the signature page hereto or such other address, notice of which is given in accordance with the provisions of this Section 18.

All such notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; five (5) business days after being deposited in the mail, postage prepaid by registered or certified mail; and on the next business day, if timely delivered by a courier guaranteeing overnight delivery.

19. Counterparts. This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so

executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

20. Headings. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

21. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware.

22. Severability. In the event that any one or more of the provisions contained herein, or the application thereof in any circumstance, is held invalid, illegal or unenforceable, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions contained herein shall not be affected or impaired thereby, and the parties (or a court if the parties cannot agree) shall insert a replacement provision that is valid and legal and that most nearly matches the parties intent of such invalid or illegal provision.

23. Entire Agreement. This Agreement is intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein with respect to the registration rights granted by the Company with respect to its securities.

24. Prior Agreement. The Prior Agreement is hereby superseded in its entirety and shall be of no further force and effect.

25. Parties Benefited. Nothing in this Agreement, unless stated expressly to the contrary, is intended to confer upon any third party any rights, remedies, obligations or liabilities.

26. Additional Registration Rights. Pursuant to Section 13(b), holders of at least 66% of the Series C Preferred Stock, by execution of this Agreement, hereby acknowledge and consent to the grant by the Company to the Investors (including the New Investors) of (a) “demand registration rights” as set forth in Section 2 of this Agreement and (b) “piggy-back registration rights” as set forth in Section 3 of this Agreement.

27. Attorneys Fees. In the event that any dispute among the parties to this Agreement should result in litigation, the prevailing party in such dispute shall be entitled to recover from the non-prevailing party all fees, costs and expenses of enforcing any right of such prevailing party under or with respect to this Agreement, including without limitation, such reasonable fees and expenses of attorneys and accountants, which shall include, without limitation, all fees, costs and expenses of appeals.

28. Aggregation of Stock. All shares of Registrable Securities held or acquired by affiliated entities or persons shall be aggregated together for the purpose of determining the availability of any rights under this Agreement.
