1.2 Request for Registration.

(a) Subject to the conditions of this Section 1.2, if the Company shall receive at any time after the earlier of (i) one hundred eighty days after the closing of a firm commitment underwritten public offering pursuant to an effective registration statement on Form S-1 under the Securities Act covering the offer and sale of Common Stock to the public for the account of the Company and (ii) the third anniversary of the date of this Agreement, a written request from the Holders of a majority of the Registrable Securities then outstanding that the Company effect a registration under the Securities Act with respect to at least a majority of the Registrable Securities then outstanding (the “Initiating Holders”), then the Company shall (x) give written notice of such request to all Holders within ten (10) calendar days of the date such request is given and (y) use its best efforts to effect as soon as practicable (and in any event within ninety (90) calendar days of the date such request is given) the registration under the Securities Act of all Registrable Securities that the Holders request to be registered within twenty (20) calendar days of the date the Company’s notice referred to in this subsection 1.2(a) is given.

(b) If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to subsection 1.2(a) and the Company shall include such information in the written notice referred to in subsection 1.2(a). The underwriter will be selected by the Company and shall be reasonably acceptable to a majority in interest of

the Initiating Holders. In such event, the right of any Holder to include its Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company as provided in subsection 1.4(e)) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting. Notwithstanding any other provision of this Section 1.2, if the underwriter advises the Initiating Holders in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Company shall so advise all Holders of Registrable Securities that would otherwise be underwritten pursuant hereto, and the number of shares of Registrable Securities that may be included in the underwriting shall be allocated among all Holders electing to include shares in the underwriting, including the Initiating Holders, in proportion (as nearly as practicable) to the amount of Registrable Securities requested by each such Holder to be included in such underwriting; provided, however, that the number of shares of Registrable Securities to be included in such underwriting shall not be reduced unless all other securities (including those to be sold for the Company’s account) are first entirely excluded from the underwriting.

(c) Notwithstanding the foregoing, if the Company shall furnish to the Initiating Holders a certificate signed by the Company’s Chief Executive Officer or President stating that in the good faith judgment of the Company’s Board of Directors, such registration would be seriously detrimental to the Company and its stockholders and that it is, therefore, essential to defer taking action with respect to such registration, the Company shall have the right to defer taking action with respect to such filing for a period of not more than one hundred twenty (120) calendar days after the date the request of the Initiating Holders is given; provided, however, that the Company may not utilize this right more than once in any twelve (12) month period; provided, further, that the Company shall not register any securities for the account of itself or any other stockholder during such period other than (i) a registration statement relating either to the sale of securities to employees of the Company pursuant to a stock option, stock purchase, stock incentive or stock appreciation plan or arrangement, (ii) a transaction pursuant to Rule 145 promulgated under the Securities Act, (iii) a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt securities that are also being registered, or (iv) a registration in connection the initial public offering of the Company’s securities (provided that, in the case of (iv), the Company has complied with its obligations under Section 1.3).

(d) In addition, the Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to this Section 1.2:

(i) after the Company has effected three (3) registrations pursuant to this Section 1.2 and such registrations have been declared or ordered effective;

(ii) during the period starting with the date sixty (60) calendar days prior to the Company’s good faith estimate of the date of filing of, and ending on a date one hundred eighty (180) calendar days after the effective date of, any registration statement pertaining to a public offering of securities for the Company’s account; provided, that the Company is actively employing its best efforts to cause such registration statement to be effective;

(iii) in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act; or

(iv) if the Initiating Holders propose to dispose of shares of Registrable Securities that may be immediately registered on Form S-3 pursuant to a request made pursuant to Section 1.11.

1.3 Company Registration. If the Company proposes to register any of its stock or other securities either for its own account or the account of a stockholder or stockholders exercising their respective demand registration rights (other than (i) a registration pursuant to Sections 1.2 or 1.11, (ii) a registration relating solely to employee benefit or similar plans, (iii) a registration relating to a Rule 145 transaction or (iv) a registration on any form which does not permit secondary sales or does not include substantially the same information as would be required to be included in a registration statement covering the Registrable Securities), the Company shall, at such time, promptly give each Holder written notice of such registration. Upon the written request of each Holder given within twenty (20) calendar days of the date such notice is given, the Company shall, subject to the provisions of Section 1.7, include in the registration all of the Registrable Securities that each such Holder has requested to be registered.

1.4 Obligations of the Company. Whenever required under this Section 1 to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible:

(a) Prepare and file with the Commission a registration statement with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective, and to keep such registration statement effective for a period of up to forty-five (45) calendar days or any lesser period of time in the event the distribution described in the registration statement has been completed.

(b) Prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement;

(c) Furnish to the Holders such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them;

(d) Use its best efforts to register and qualify the securities covered by such registration statement under such other securities or blue sky laws of such jurisdictions as shall be reasonably requested by the Holders; provided, that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act;

(e) In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter(s) of such offering (each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement);

(f) Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing;

(g) Cause all such Registrable Securities registered pursuant hereunder to be listed on each securities exchange or nationally recognized quotation system on which similar securities issued by the Company are then listed; and

(h) Provide a transfer agent and registrar for all Registrable Securities registered pursuant hereunder and a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration.

1.5 Furnish Information. It shall be a condition precedent to the Company’s obligations to take any action pursuant to this Section 1 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding such Holder, the Registrable Securities held by such Holder, and the intended method of disposition of such securities as shall be reasonably required by the Company or the managing underwriters, if any, to effect the registration of such Holder’s Registrable Securities.

1.6 Expenses of Registrations. All expenses (other than underwriting discounts and commissions) incurred in connection with registrations, filings or qualifications pursuant to Sections 1.2, 1.3 or 1.11, including (without limitation) all registration, filing and qualification fees, printer’s fees, accounting fees and fees and disbursements of counsel for the Company (including fees and disbursements of counsel for the Company in its capacity as counsel to the selling Holders hereunder; but if Company counsel does not make itself available for this purpose, the Company will pay the reasonable fees and disbursements of one counsel for the selling Holders) shall be borne by the Company; provided, however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Sections 1.2 or 1.11 if the registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered (in which case all participating Holders shall bear such expenses on a pro rata basis based on the number of Registrable Securities proposed to be registered by each such Holder), unless the Holders of a majority of the Registrable Securities agree to forfeit their right to one demand registration pursuant to Section 1.2; provided further, however, that if at the

time of such withdrawal, the Holders have learned of a material adverse change in the condition, business, or prospects of the Company and such material adverse change was not known to the Holders at the time of their request and have withdrawn the request with reasonable promptness following disclosure by the Company of such material adverse change, then the Holders shall not be required to pay any of such expenses and shall not forfeit their right to one (1) demand registration pursuant to Section 1.2; and provided further, that changes resulting solely from the condition of the stock market substantially equally affecting all similarly situated companies shall not be deemed to be a material adverse change in the condition, business or prospects of the Company. Registrations effected pursuant to Section 1.11 shall not be counted as demands for registration or registrations effected pursuant to Section 1.2 or 1.3, respectively.

1.7 Underwriting Requirements. If the registration statement under which the Company gives notice under Section 1.3 is for an underwritten offering, the Company shall so advise the Holders. In such event, all Holders proposing to distribute their securities through such underwriting shall (together with the Company as provided in subsection 1.4(e)) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting. If the total amount of securities, including Registrable Securities requested by stockholders to be included in such offering, exceeds the amount of securities sold other than by the Company that the underwriters determine in their sole discretion is compatible with the success of the offering, then the Company shall be required to include in the offering only that number of such securities, including Registrable Securities, which the underwriters determine in their sole discretion will not jeopardize the success of the offering (the securities so included to be apportioned pro rata among the selling stockholders according to the total amount of securities requested to be included therein by each such selling stockholder or in such other proportions as shall mutually be agreed to by such selling stockholders), but in no event shall (i) the amount of securities of the selling Holders included in the offering be reduced unless the securities of all other selling stockholders included in the offering are entirely excluded and (ii) the amount of securities of the selling Holders included in the offering be reduced below thirty percent (30%) of the total amount of securities included in such offering, unless such offering is the Qualified IPO of the Company’s securities, in which case such Holders may be excluded entirely if the underwriters make the determination described above and if the securities of all other selling stockholders are excluded entirely. For purposes of the preceding parenthetical concerning apportionment, for any selling stockholder which is a Holder of Registrable Securities and which is a partnership, limited liability company or corporation, the partners (or retired partners), members (or retired members) and stockholders of such selling stockholder, or the estates and family members of any such partners (or retired partners), members (or retired members) or stockholders and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single “selling stockholder” and any pro rata reduction with respect to such “selling stockholder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “selling stockholder” as defined in this sentence.

1.8 Delay of Registration. No 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 Section 1.

1.9 Indemnification.

(a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder, its officers, directors, partners or former partners, and members or former members, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder, its officers, directors, partners or former partners, and members or former members, or underwriter within the meaning of the Securities Act or the Exchange Act (each an “Indemnified Person”), against any losses, claims, damages, or liabilities (joint or several) to which any of the foregoing persons may become subject under the Securities Act, the Exchange Act or other federal or state or other applicable securities law, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively, a “Violation”): (i) any untrue statement or alleged untrue statement of a material fact contained in a registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto (collectively, the “Filings”); (ii) the omission or alleged omission to state in the Filings 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 or other applicable securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law; and the Company will pay, as incurred, any legal or other expenses reasonably incurred by any Indemnified Person in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this subsection 1.9(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld or delayed), nor shall the Company be liable to such Indemnified Person 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 a Violation that occurs in reliance upon and in conformity with written information furnished to the Company expressly for use in connection with such registration by an Indemnified Person.

(b) To the extent permitted by law, each selling Holder will severally and not jointly indemnify and hold harmless the Company, each of its directors, each of its officers, each person, if any, who controls the Company within the meaning of the Securities Act, any underwriter, any other Holder selling securities in such registration statement and any controlling person of any such underwriter or other Holder, against any losses, claims, damages, or liabilities (joint or several) to which any of the foregoing persons may become subject under the Securities Act, the Exchange Act or other federal or state securities law insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in the registration statement in connection with such Filings; and each such Holder will pay, as incurred, any legal or other expenses reasonably incurred by any person to be indemnified pursuant to this subsection 1.9(b) in connection with investigating or defending any such loss,

claim, damage, liability or action; provided, however, that the indemnity agreement contained in this subsection 1.9(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 consent of the Holder (which consent shall not be unreasonably withheld or delayed); provided, however, in no event shall the obligations of any Holder under this subsection 1.9(b) exceed the net proceeds from the shares of Registrable Securities sold in the offering and received by such Holder.

(c) Promptly after receipt by an indemnified party under this Section 1.9 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 1.9, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an 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, with the fees and expenses to be paid by the indemnifying party, 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 such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall relieve such indemnifying party of liability to the indemnified party under this Section 1.9, but only to the extent such failure to deliver written notice is materially prejudicial to the indemnifying party’s ability to defend such action.

(d) If the indemnification provided for in Section 1.9(a) and (b) is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, claim, damage or expense referred to therein, 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, 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 or alleged statements or omissions that resulted in such loss, liability, claim 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 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. In no event shall any Holder be required to contribute an amount, when combined with any amounts paid pursuant to Section 1.9(b), that exceeds the net proceeds from the shares of Registrable Securities sold in the offering and received by such Holder.

(e) The obligations of the Company and Holders under this Section 1.9 shall survive the completion of any offering of Registrable Securities in a registration statement under this Section 1, and the termination of this Agreement.

1.10 Reports Under Securities Exchange Act. With a view to making available the benefits of certain rules and regulations of the Commission, including Rule 144, which may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company agrees to:

(a) Make and keep public information available, as those terms are understood and defined in Rule 144 after the effective date of the first registration statement filed by the Company for the offering of its securities to the general public;

(b) Take such action, including the registration of its Common Stock under Section 12 of the Exchange Act, as is necessary to enable the Holders to utilize Form S-3 for the sale of their Registrable Securities, such action to be taken as soon as practicable after the end of the fiscal year in which the first registration statement filed by the Company for the offering of its securities to the general public is declared effective;

(c) 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; and

(d) Furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any time after it so qualifies), (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the Commission that permits the selling of any such securities without registration or pursuant to such form.

1.11 Form S-3 Registration.

(a) Subject to the conditions of this Section 1.11, if the Company shall receive from the Holders of a majority of the Registrable Securities then outstanding a written request that the Company effect a registration on Form S-3 and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holder(s), then the Company shall (a) promptly give written notice of the proposed registration, and any related qualification or compliance, to all other Holders and (b) use its best efforts to effect, as soon as practicable, such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of the Registrable Securities specified in such request, together with all or such portion of the Registrable Securities of any other Holder joining in such request as are specified in a written request given within fifteen (15) calendar days of the date the Company’s notice referred to in clause (a) of this sentence is given.

(b) If the Holders requesting registration pursuant to this Section 1.11 intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as part of their request made pursuant to this Section 1.11 and the Company shall include such information in the written notice referred to in

clause (a) of Section 1.11(a). The underwriter will be selected by the Company and shall be reasonably acceptable to a majority in interest of the Holders requesting registration. In such event, the right of any Holder to include its Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company as provided in Section 1.4(e)) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting. Notwithstanding any other provision of this Section 1.11, if the underwriter advises the Holders requesting registration in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Holders requesting registration shall so advise all Holders of Registrable Securities that would otherwise be underwritten pursuant hereto, and the number of shares of Registrable Securities that may be included in the underwriting shall be allocated among all Holders thereof, including the Holders requesting registration, in proportion (as nearly as practicable) to the amount of Registrable Securities requested by each such Holder to be included in such underwriting; provided, however, that the number of shares of Registrable Securities to be included in such underwriting shall not be reduced unless all other Securities (including those to be sold for the Company’s account) are first entirely excluded from the underwriting.

(c) Notwithstanding the foregoing, if the Company shall furnish to the Holder(s) requesting a registration pursuant to this Section 1.11, a certificate signed by the Company’s Chief Executive Officer or President stating that in the good faith judgment of the Company’s Board of Directors, such registration would be seriously detrimental to the Company and its stockholders and that it is, therefore, essential to defer taking action with respect to such registration, the Company shall have the right to defer taking action with respect to such filing for a period of not more than one hundred twenty (120) calendar days after the date the request of the Holder(s) requesting a registration pursuant to this Section 1.11 is given; provided, however, that the Company shall not utilize this right more than once in any twelve (12) month period.

(d) In addition, the Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to this Section 1.11:

(i) if Form S-3 is not available for such offering by the Holders;

(ii) if the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public (net of underwriting discounts and commissions) of less than $10,000,000;

(iii) during the period starting with the date sixty (60) calendar days prior to the Company’s good faith estimate of the date of filing of, and ending on a date one hundred eighty (180) calendar days after the effective date of, any registration statement pertaining to an underwritten public offering of securities for the Company’s account; provided that the Company is actively employing its best efforts to cause such registration statement to be effective; or

(iv) in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act.

(a) As soon as practicable, but in any event within one hundred-eighty (180) calendar days after the end of each fiscal year of the Company, consolidated balance sheets of the Company and its subsidiaries, if any, as of the end of such fiscal year, and consolidated statements of income and consolidated statements of cash flows of the Company and its subsidiaries, if any, for such year, prepared in accordance with generally accepted accounting principles (“GAAP”), all in reasonable detail and audited by independent public accountants of national or regional standing selected by the Board of Directors of the Company; and

2.2 Visitation and Inspection. The Company shall permit each Qualified Holder, at such Qualified Holder’s expense, to visit and inspect the Company’s properties, to examine its books of account and records and to discuss the Company’s affairs, finances and accounts with its officers, all at such reasonable times during business hours as may be requested by the Qualified Holder; provided, however, that the Company shall not be obligated pursuant to this Section 2.2 to provide access to any information that it reasonably considers in good faith to be a trade secret or similar confidential information. The provisions of this Section 2.2 shall not be in limitation of any rights which any Investor may have with respect to the books and records of the Company and its subsidiaries, or to inspect their properties or discuss their affairs, finances and accounts, under the laws of the State of Delaware.

2.3 Right of First Offer. Subject to the terms and conditions specified in this Section 2.3, the Company hereby grants to each Qualified Holder (each, an “Offeree”), a right of first offer to subscribe for and purchase such Offeree’s Pro Rata Share (as hereinafter defined for the purpose of this Section 2.3), in whole or in part, of future issuances by the Company of Future Shares (as hereinafter defined). Notwithstanding Section 2.5(b), each Offeree shall be entitled to assign or apportion the right of first offer among its partners and affiliates (including, in the case of a venture capital fund, other venture capital funds affiliated with such fund) in such proportions as

it deems appropriate. For purposes of this Section 2.3, an Offeree’s “Pro Rata Share” of Future Shares shall be a fraction, the numerator of which is the number of shares of Common Stock issued or issuable upon conversion of the Preferred Stock held by such Offeree immediately prior to the issuance of Future Shares (assuming the full conversion and exercise of all outstanding securities convertible into or exercisable for Preferred Stock held by such investor and excluding Special Mandatory Conversion Shares) and the denominator of which is the total number of shares of the Company’s Common Stock issued or issuable to all Offerees upon conversion of all Preferred Stock held by all Offerees (assuming full conversion and exercise of all outstanding securities convertible into or exercisable for Preferred Stock held by all Offerees and excluding Special Mandatory Conversion Shares) immediately prior to the issuance of Future Shares. Each time the Company proposes to offer any shares of, or securities convertible into or exercisable for any shares of, any class of its capital stock (“Future Shares”), the Company shall first make an offering of such Future Shares to each Offeree in accordance with the following provisions:

(a) The Company shall deliver a notice (“Notice”) to each Offeree stating (i) the Company’s bona fide intention to offer such Future Shares, (ii) the number of such Future Shares to be offered, and (iii) the price and a summary of the terms, if any, upon which it proposes to offer such Future Shares.

(b) Each Offeree may elect to subscribe for and purchase, at the price and on the terms specified in the Notice, (i) up to such Offeree’s Pro Rata Share of the Future Shares and (ii) such additional number of the Future Shares as such Offeree indicates it is willing to purchase should the other Offerees subscribe for less than their respective Pro Rata Shares (for each Offeree, the “Additional Portion”) by notifying the Company in writing within ten (10) calendar days from the date the Notice is given by the Company.

(c) If the aggregate number of Future Shares subscribed for pursuant to subsection (a) above is less than the aggregate Pro Rata Share for which all Offerees are entitled to subscribe, then each Offeree who has subscribed for an Additional Portion pursuant to subsection (a) above shall be entitled to purchase, in addition to such Offeree’s Pro Rata Share, the Additional Portion subscribed for by such Offeree; provided, however, that if the Additional Portions subscribed for by all Offerees exceed the difference obtained by subtracting (x) the aggregate Pro Rata Share for which all Offerees are entitled to subscribe from (y) the number of Future Shares subscribed for by all Offerees (the “Available Additional Portion”), then each Offeree who has subscribed for an Additional Portion shall be entitled to purchase only that portion of the Available Additional Portion as such Offeree’s Pro Rata Share bears to the aggregate Pro Rata Share for all Offerees who subscribed for an Additional Portion, subject to rounding by the Company’s Board of Directors to the extent it reasonably deems necessary and equitable. To the extent that Future Shares are not purchased by the Offerees as provided in subsection (a) above and this subsection (c), the Company may, during the ninety (90) calendar days following the expiration of the period provided in subsection (a) above, offer the remaining unsubscribed portion of such Future Shares to any person or persons at a price not less than and upon terms no more favorable than those specified in the Notice. If the Company does not enter into an agreement for the sale of the Future Shares within such period, or if such agreement is not consummated within thirty (30) calendar days of the execution thereof, the right provided in this Section 2.3 shall be deemed to be revived and such Future Shares shall not be offered unless first reoffered to the Offerees in accordance herewith.

(d) The right of first offer in this Section 2.3 shall not be applicable to the issuance of (i) the Shares issued pursuant to the Series E Agreement; (ii) the Conversion Stock or Special Mandatory Conversion Shares; (iii) securities issued as a dividend or distribution on the Shares; (iv) securities issued in connection with any stock split of or stock dividend on the Common Stock or the Preferred Stock; (v) securities issued to the Company’s employees, officers, directors, consultants, advisors or services providers pursuant to the Company’s 2005 Stock Plan (or other plan, agreement or similar arrangement approved by the Company’s Board of Directors), provided, such issuance is approved by a majority of the Company’s Board of Directors; (vi) securities issued to vendors, banks or equipment lessors, provided, such issuance is approved by the Company’s Board of Directors with such approval including at least two (2) Preferred Directors (as defined in the Restated Certificate) and is primarily for non-equity financing purposes; (vii) securities issued in connection with sponsored research, collaboration, technology license, development, OEM, marketing or other similar agreements or strategic partnerships; provided, such issuance is approved by the Company’s Board of Directors with such approval including at least two (2) Preferred Directors and is primarily for non-equity financing purposes; (viii) securities issued in a firm commitment underwritten public offering pursuant to an effective registration statement under the Securities Act pursuant to which all outstanding shares of each series of Preferred Stock are converted to Common Stock; (ix) securities issued in connection with a bona fide business acquisition of or by the Company (whether by merger, consolidation, sale of assets, sale or exchange of stock or otherwise), provided, such acquisition is approved by the Company’s Board of Directors with such approval including at least two (2) Preferred Directors; or (x) any right, option or warrant to acquire any security convertible into or exercisable for the securities listed in clauses (i) through (ix) above.

(e) Notwithstanding Section 5.2 hereof, in the event the Company proposes to offer Future Shares pursuant to which Qualified Holders are entitled to a right of first offer pursuant to this Section 2.3, and such right of first offer is waived on behalf of all Qualified Holders pursuant to Section 5.2 hereof, if any Qualified Holder is allowed to purchase any of such Future Shares, then each other Qualified Holder shall be entitled to purchase its Pro Rata Portion of all such Future Shares.

(f) Each Existing Investor hereby (i) consents to the Company issuing shares of its Series E Preferred Stock pursuant to the Series E Agreement, as the same may be amended from time to time, (ii) waives any and all rights of first offer such Existing Investor has under Section 2.3 of the Prior Agreement, including but not limited to the right to purchase any portion of the Company’s Series E Preferred Stock, including any of the Company’s Common Stock issued upon conversion thereof and (iii) waives any required notice under the Prior Agreement or otherwise of the Company’s intention to issue shares of its Series E Preferred Stock. The waiver set forth in this subsection (f) shall become effective and binding on all Existing Investors upon the execution of this Agreement by the Company and by Existing Investors holding at least a majority of the Registrable Securities (as defined in the Prior Agreement).

Unless otherwise determined by the Company’s Board of Directors (including at least two (2) of the Preferred Directors), any restricted stock to which this Section 2.4(c) applies shall be subject to the Company’s right to repurchase any shares of unvested stock at the purchase price paid by the holder, a right of first refusal in favor of the Company to purchase any vested stock at the price offered by a third party, a restriction on the transfer of unvested stock, and such stock shall vest on the same schedule as set forth in the preceding sentence.
