(b)    Underwriting. If the Holders initiating the registration request under this Section 2.2 (the “Initiating Holders”) intend to distribute the Class A Registrable Securities covered by their request by means of an underwriting, then they shall so advise the Company as a part of their request made pursuant to this Section 2.2 and the Company shall include such information in the written notice referred to in Section 2.2(a). In such event, the right of any Holder to include his, her, or its Class A Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Class A Registrable Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the Initiating Holders and such Holder) to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement with the managing underwriter or underwriters selected for such underwriting by the Investors holding a majority in interest of the Registrable Securities included in

4

such registration and approved by the Company (such approval not be unreasonably withheld). Notwithstanding any other provision of this Section 2.2, if the underwriter(s) advise(s) the Company in writing that marketing factors require a limitation of the number of securities to be underwritten, then the Company shall so advise all Holders of Class A Registrable Securities that would otherwise be registered and underwritten pursuant hereto, and the number of Class A Registrable Securities that may be included in the underwriting shall be reduced as required by the underwriter(s) and allocated among the Holders of Class A Registrable Securities on a pro rata basis according to the number of Class A Registrable Securities then Outstanding held by each Holder requesting registration (including the Initiating Holders); provided, however, that the number of shares of Class A Registrable Securities to be included in such underwriting and registration shall not be reduced unless all other securities of the Company and any other Holders requesting registration are first entirely excluded from the underwriting and registration. Any Class A Registrable Securities excluded and withdrawn from such underwriting shall be withdrawn from the registration.

(c)    Maximum Number of Demand Registrations. The Company shall in no event be obligated to effect more than two (2) registrations pursuant to this Section 2.2.

(d)    Deferral. Notwithstanding the foregoing, if the Company shall furnish to the Holders requesting the filing of a registration statement pursuant to this Section 2.2, a certificate signed by the President, Chief Executive Officer or Chief Financial Offer of the Company stating that in the good faith judgment of the Board of Directors of the Company (the “Board”), it would be detrimental to the Company and its stockholders for such registration statement to be filed and it is therefore essential to defer the filing of such registration statement, then the Company shall have the right to defer such filing for a period of not more than one hundred twenty (120) days after receipt of the request of the Initiating Holders; 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 its own account during such one hundred twenty (120) day period.

(e)    Restrictions.    The Company shall not be obligated to effect any registrations:

(1)    During the one hundred eighty (180) day period after the effective date of a Company-initiated registration;

(2)    If the Company delivers notice to the Initiating Holders, within thirty (30) days after the receipt of their written request, of its intent to file a registration statement for an initial public offering with the SEC within ninety (90) days; or

(3)    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.

(f)    Expenses. All expenses incurred in connection with a registration pursuant to this Section 2.2, including without limitation all registration and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for the Company, and the reasonable fees and disbursements of one counsel for the selling Holders (but excluding underwriters’ discounts and commissions), shall be borne by the Company. Each Holder participating in a registration pursuant to this Section 2.2 shall bear such Holder’s proportionate share (based on the number of shares sold by such Holder over the total number of shares included in such registration at the time it is declared effective) of all discounts, commissions or other amounts payable to underwriters or brokers in connection with such offering. Notwithstanding the foregoing, the Company shall not be required to pay for any expenses of

5

any registration proceeding begun pursuant to this Section 2.2 if the registration request is subsequently withdrawn at the request of the Holders of a majority of the Class A Registrable Securities to be registered, unless (i) the Holders of a majority of the Class A Registrable Securities then Outstanding agree to forfeit their right to one demand registration pursuant to this Section 2.2 (in which case such right shall be forfeited by all Holders of Class A Registrable Securities), or (ii) the withdrawal is based upon material adverse information concerning the Company of which the Initiating Holders were not aware at the time of such request.

2.3    Piggyback Registrations. The Company shall notify all Holders of Registrable Securities in writing at least thirty (30) days prior to filing any registration statement under the Securities Act for purposes of effecting a public offering of securities of the Company (including, but not limited to, registration statements relating to secondary offerings of securities of the Company, but excluding registration statements relating to any registration under Section 2.4 of this Agreement or to any employee benefit plan or a corporate reorganization or other transaction covered by Rule 145 promulgated under the Securities Act), and will afford each such Holder an opportunity to include in such registration statement all or any part of the Registrable Securities then held by such Holder. Each Holder desiring to include in any such registration statement all or any part of the Registrable Securities held by such Holder shall, within twenty (20) days after receipt of the above-described notice from the Company, so notify the Company in writing, and in such notice shall inform the Company of the number of Registrable Securities such Holder wishes to include in such registration statement. If a Holder decides not to include all of its Registrable Securities in any registration statement thereafter filed by the Company, such Holder shall nevertheless continue to have the right to include any Registrable Securities in any subsequent registration statement or registration statements as may be filed by the Company with respect to offerings of its securities, all upon the terms and conditions set forth herein.

(a)    Underwriting. If a registration statement under which the Company gives notice under this Section 2.3 is for an underwritten offering, then the Company shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder’s Registrable Securities to be included in a registration pursuant to this Section 2.3 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 Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the managing underwriter or underwriter(s) selected for such underwriting. Notwithstanding any other provision of this Agreement, if the managing underwriter determine(s) in good faith that marketing factors require a limitation of the number of shares to be underwritten, then the managing underwriter(s) may exclude shares (including Registrable Securities) from the registration and the underwriting, and the number of shares that may be included in the registration and the underwriting shall be allocated, first, to the Company (and, if the registration is pursuant to Section 2.2 hereof, the Initiating Holders on a pro rata basis), second to Holders requesting inclusion of their Registrable Securities in such registration statement on a pro rata basis based on the number of Registrable Securities held by each such Holder, and third to any other stockholder of the Company (other than a Holder). Notwithstanding the foregoing, however:

(1)    the right of the underwriters to exclude Class A Registrable Securities from the registration and underwriting as described above shall be restricted so that the number of Class A Registrable Securities included in any such registration is not reduced in the aggregate below 30% of the shares included in the registration (except for a registration relating to the Company’s initial public offering and such registration does not include shares of any other selling stockholders, from which all Registrable Securities may be excluded, and without limitation to the rights of holders of SiteScout Registrable Securities pursuant to clause (2) below),

6

(2)    in a registration and underwriting of the Company’s first public offering that is effected after, or concurrently with, the exchange of Exchangeable Securities for Class A Common Stock or Class B Common Stock of the Company (the “Exchange”), the right of the underwriters to exclude SiteScout Registrable Securities from the registration and underwriting as described above shall be restricted so that the number of SiteScout Registrable Securities included in any such registration on behalf of any holder thereof that is identified as an Investor in Exhibit A hereto is not reduced in the aggregate below the Applicable Tax Percentage (as defined below) of such holder’s SiteScout Registrable Securities (the “Minimum SiteScout Shares”), if, and only if (i) the Exchange was effected at the election of the Company, and not of the SiteScout Shareholders, (ii) the Minimum SiteScout Shares (to the extent not sold in such offering) are subject to an underwriter lockup restricting resale for at least 90 days, (iv) the Company has not waived its rights with respect to the Minimum SiteScout Shares (if not sold in such offering) pursuant to Section 2.9 hereof and Section 5.12 of the SiteScout Purchase Agreement and (v) the Company has not made available to each of such holders a loan, to be funded at, or promptly after, the consummation of such public offering, pursuant to customary and reasonable documents, (1) in a principal amount equal to the Applicable Tax Percentage multiplied by the product of (A) the number of SiteScout Registrable Securities held by such holder multiplied by (B) the initial public offering price, (2) with an interest rate equal to the applicable federal rate for a one-year loan under United States federal income tax regulations (if (a) applicable to such loan based on status of the SiteScout Shareholders and (b) the failure to provide for such interest would have adverse consequences to the Company), (3) with a term of one year (subject to mandatory prepayment with the proceeds of any sale of SiteScout Registrable Securities), (4) that is (at the election of the Company) unsecured, or secured by a pledge of the SiteScout Registrable Securities, and (5) otherwise on customary and reasonable terms. The foregoing limitation on the right of underwriters to exclude SiteScout Registrable Securities shall not limit the rights of the holders of Class A Registrable Securities pursuant to clause (1) above. The “Applicable Tax Percentage” means 22% with respect to any person identified as a “Founder” on Exhibit A hereto, and 45% with respect to any holder of SiteScout Registrable Securities that is listed on Exhibit A hereto and not so identified as a “Founder.”

(3)    no Holder of Registrable Securities who has requested to be included in a registration pursuant to this Section 2.3 shall be granted such registration without the consent of the Initiating Holders, such consent not to be unreasonably withheld in the case of a registration that is the Company’s initial public offering notwithstanding that the requested registration of such Holder’s Registrable Securities would reduce the number of shares includable by the Initiating Holders and

(4)    no stockholders of the Company other than the Investors shall be included in any such registration without the consent of holders of a majority of the Registrable Securities. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice, given in accordance with Section 6.1 hereof, to the Company and the underwriter, delivered at least twenty (20) days prior to the effective date of the registration statement.

Any Registrable Securities excluded or withdrawn from such underwriting shall be excluded and withdrawn from the registration. For any Holder that is a partnership or corporation, the partners, retired partners and stockholders of such Holder, or the estates and family members of any such partners and retired partners and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single “Holder,” and any pro rata reduction with respect to such “Holder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “Holder,” as defined in this sentence.

7

(b)    Expenses. All expenses incurred in connection with a registration pursuant to this Section 2.3, including without limitation all registration and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for the Company, and the reasonable fees and disbursements of one counsel for the selling Holders (but excluding underwriters’ discounts and commissions), shall be borne by the Company. Each Holder participating in a registration pursuant to this Section 2.3 shall bear such Holder’s proportionate share (based on the number of shares sold by such Holder over the total number of shares included in such registration at the time it goes effective) of all discounts, commissions or other amounts payable to underwriters or brokers in connection with such offering.

2.4    Form S-3 Registration. In case the Company shall receive from any Holder or Holders of at least 20% of the Registrable Securities then Outstanding a written request or requests that the Company effect a registration on Form S-3 (or any successor to Form S-3) and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holder or Holders, then the Company will do the following:

(a)    Notice. Promptly give written notice of the proposed registration and the Holder’s or Holders’ request therefor, and any related qualification or compliance, to all other Holders of Registrable Securities.

(b)    Registration. As soon as practicable, effect 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 such Holder’s or Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within twenty (20) days after receipt of such written notice from the Company; provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance pursuant to this Section 2.4:

(1)    if Form S-3 is not available for such offering;

(2)    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 of less than $1,000,000;

(3)    if the Company shall furnish to the Holders a certificate signed by the President, Chief Executive Officer or Chief Financial Officer of the Company stating that in the good faith judgment of the Board, it would be detrimental to the Company and its stockholders for such Form S-3 Registration to be effected at such time, in which event the Company shall have the right to defer the filing of the Form S-3 no more than once during any twelve (12) month period for a period of not more than one hundred twenty (120) days after receipt of the request of the Holder or Holders under this Section 2.4;

(4)    if the Company has, within the twelve (12) month period preceding the date of such request, already effected two (2) registrations on Form S-3 for the Holders pursuant to this Section 2.4; or

(5)    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.

(c)    Expenses. Subject to the foregoing, the Company shall file a Form S-3 covering the Registrable Securities and other securities so requested to be registered pursuant to this

8

Section 2.4 as soon as practicable after receipt of the request or requests of the Holders for such registration. The Company shall pay all expenses incurred in connection with each registration requested pursuant to this Section 2.4, (excluding underwriters’ discounts and commissions), including without limitation all filing, registration and qualification, printers’ and accounting fees and the reasonable fees and disbursements of one (1) counsel for the selling Holder or Holders and counsel for the Company. Each Holder participating in a registration pursuant to this Section 2.4 shall bear such Holder’s proportionate share (based on the number of shares sold by such Holder over the total number of shares included in such registration at the time it goes effective) of all discounts, commissions or other amounts payable to underwriters or brokers in connection with such offering.

(d)    Not Demand Registration. Form S-3 registrations shall not be deemed to be demand registrations as described in Section 2.2 above.

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

(a)    Prepare and file with the SEC a registration statement with respect to such Registrable Securities and use commercially reasonable efforts to cause such registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective for up to ninety (90) days.

(b)    Prepare and file with the SEC 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 and, in connection with any registration on Form S-3 pursuant to Section 2.4 above, use reasonable, diligent efforts to timely file all reports required under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), in order to maintain the right to continue to use such Form and to maintain such registration in effect.

(c)    Furnish to the Holders such number 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 the Registrable Securities owned by them that are included in such registration.

(d)    Use its commercially reasonable 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.

(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 hereby agrees to 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

9

circumstances then existing. The Company will use reasonable efforts to amend or supplement such prospectus in order to cause such prospectus not to include any untrue statement of a material fact or omit 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)    Use its commercially reasonable efforts to 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.

(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.

2.6    Furnish Information. It shall be a condition precedent to the obligations of the Company to take any action pursuant to Sections 2.2, 2.3 or 2.4 that the selling Holders shall furnish to the Company such information regarding themselves, the Registrable Securities held by them, and the intended method of disposition of such securities as shall be required to timely effect the registration of their Registrable Securities.

2.7    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 2.

2.8    Indemnification. In the event any Registrable Securities are included in a registration statement under Sections 2.2, 2.3 or 2.4:

(a)    By the Company. To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the partners, members, officers and directors of each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder 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 they may become subject under the Securities Act, the Exchange Act or other federal or state 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, the “Violations” and, individually, a “Violation”):

(1)    any untrue statement or alleged untrue statement of a material fact contained in such registration statement or incorporated reference therein, including any preliminary prospectus or final prospectus contained therein, any free-writing prospectus as defined in Rule 405 promulgated under the Securities Act or any amendments or supplements thereto; or

(2)    the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading; or

(3)    any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any federal or state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any federal or state securities law in connection with the offering covered by such registration statement.

The Company will reimburse each such Holder, partner, member, officer or director, underwriter or controlling person for any legal or other expenses reasonably incurred by them, within ten (10) business days after a request for reimbursement has been received by the Company, in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the

10

indemnity agreement contained in this subsection 2.8(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), nor shall the Company 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 a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such Holder, partner, member, officer, director, underwriter or controlling person of such Holder.

(b)    By Selling Holders. To the extent permitted by law, each selling Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration qualifications or compliance is being effected, 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 Securities Act, any underwriter and any other Holder selling securities under such registration statement or any of such other Holder’s partners, members, directors or officers or any person who controls such Holder 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 or any such director, officer, controlling person, underwriter or other such Holder, partner or director, officer or controlling person of such other Holder may become subject under the Securities Act, the Exchange Act or other federal or state 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 connection with such registration. Each such Holder will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, controlling person, underwriter or other Holder, partner, officer, director or controlling person of such other Holder in connection with investigating or defending any such loss, claim, damage, liability or action within ten (10) business days after a request for reimbursement has been received by the indemnifying Holder, provided, however, that the indemnity agreement contained in this subsection 2.8(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; and provided further, that the total amounts payable in indemnity by a Holder under this Section 2.8(b) in respect of any Violation shall not exceed the net proceeds received by such Holder in the registered offering out of which such Violation arises.

(c)    Notice. Promptly after receipt by an indemnified party under this Section 2.8 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 2.8, deliver to the indemnifying party a written notice of the commencement thereof. 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 shall have the right to retain its own counsel, with the fees and expenses thereof 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 conflict of 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, if prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 2.8, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 2.8.

11

(d)    Contribution. If the indemnification provided for in this Section 2.8 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 the indemnified party, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party with respect to such loss, liability, claim, damage or expense in the proportion that is appropriate to reflect the relative fault of the indemnifying party and the indemnified party in connection with the Violations 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 the indemnified party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of 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. In any such case, (A) no such Holder will be required to contribute any amount in excess of the net proceeds from the offering received by such Holder; and (B) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation; provided, that in no event shall a Holder’s liability pursuant to this Section 2.8(d), when combined with the amounts paid or payable by such Holder pursuant to Section 2.8(b), exceed the net proceeds from the offering received by such Holder, except in the case of willful misconduct or fraud by such Holder.

(e)    Conflict with Underwriting Agreement. 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 will control.

(f)    Survival. The obligations of the Company and Holders under this Section 2.8 shall survive the completion of any offering of Registrable Securities in a registration statement, and with respect to liability arising from an offering to which this Section 2.8 would apply that is covered by a registration filed before termination of this Agreement, such termination.

2.9    “Market Stand-Off” Agreement. If, but only if, all persons then serving as officers or directors of the Company, and each holder of more than one percent of the Company’s outstanding Common Stock (including shares issuable on conversion of preferred stock and upon the Exchange ) are bound by and have entered into a similar agreement, each Holder hereby agrees that upon the prior written request of the managing underwriter, it will not 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 (l80) days, which period may be extended upon the request of the managing underwriter, to the extent required by any rules of the securities exchange or trading system on which the Company’s securities are listed, for an additional period of up to eighteen (18) days if the Company issues or proposes to issue an earnings or other public release) (34 days if the Company issues an earnings or other public release within such 18 day period), (a) 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 Class A Common Stock, Class B Common Stock or any securities convertible into or exercisable or exchangeable for Class A Common Stock (whether such shares or any such securities are then owned by the Holder or are thereafter acquired), or (b) 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 Class A Common Stock or Class B Common Stock, whether any such transaction described in clause (a) or (b) above is to be settled by delivery of Class A Common Stock or Class B Common Stock or such other securities, in cash or otherwise. The foregoing provisions

12

of this Section 2.9 shall apply only to the Company’s initial public offering of equity securities and shall not apply (i) to the sale of any shares to an underwriter pursuant to an underwriting agreement, or (ii) to a registration relating solely to employee benefit plans on Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a transaction on Form S-4 or similar forms that may be promulgated in the future. The underwriters in connection with the Company’s initial public offering 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 a party hereto. In order to enforce the foregoing covenant, the Company shall have the right to place restrictive legends on the certificates representing the shares subject to this Section and to impose stop transfer instructions with respect to the Registrable Securities and such other shares of stock of each Holder (and the shares or securities of every other person subject to the foregoing restriction) until the end of such period. Any discretionary waiver or termination of the restrictions of any or all such agreements by the Company or the underwriters (other than discretionary waivers for financial hardship for the sale of shares having an aggregate sales price not exceeding $50,000 per Holder) shall apply pro rata to all Holders subject to such agreements, based on the number of shares subject to such agreements.

2.10    Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission which may at any time permit the sale of the Registrable Securities to the public without registration, after such time as a public market exists for the Class A Common Stock or Class B Common Stock of the Company, the Company agrees to:

(a)    Make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act or any similar or analogous rule promulgated under the Securities Act, at all times after the effective date of the first registration under the Securities Act filed by the Company for an offering of its securities to the general public;

(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)    So long as a Holder owns any Registrable Securities, to furnish to the Holder forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of said Rule 144 (at any time after ninety (90) days after the effective date of the first registration statement filed by the Company for an offering of its securities to the general public), and of the Securities Act and the Exchange Act (at any time after it has become subject to the reporting requirements of the Exchange Act), a copy of the most recent annual or quarterly report of the Company, and such other reports and documents of the Company as a Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing a Holder to sell any such securities without registration (at any time after the Company has become subject to the reporting requirements of the Exchange Act).

2.11    Termination of the Company’s Obligations. The Company shall have no obligations pursuant to Sections 2.2 through 2.4 with respect to: (a) any request or requests for registration made by any Holder on a date more than five (5) years after the closing date of the Company’s initial public offering; or (b) after the Company’s initial public offering, any Registrable Securities proposed to be sold by a Holder in a registration pursuant to Sections 2.2, 2.3 or 2.4 if the Holder holds less than one half percent (1/2%) of the Company’s then-outstanding shares of Common Stock, calculated on an as-converted basis.

2.12    Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of the Holders of a majority of

13

the Registrable Securities then Outstanding, enter into any agreement with any holder or prospective holder of any securities of the Company which would allow such holder or prospective holder (a) to include such securities in any registration filed under Section 2.3 hereof, unless under the terms of such agreement, such holder or prospective holder may include such securities in any such registration only to the extent that the inclusion of his securities will not reduce the amount of the Registrable Securities of the Holders which is included, or (b) to make a demand registration.

3.    RIGHT OF FIRST REFUSAL.

3.1    General. Each Major Investor has the right of first refusal to purchase such Major Investor’s Pro Rata Share (as defined below), of all (or any part) of any “New Securities” (as defined in Section 3.2) that the Company may from time to time issue after the date of this Agreement; provided, however, such Major Investor shall have no right to purchase any such New Securities if such Major Investor cannot demonstrate to the Company’s reasonable satisfaction that such Major Investor is at the time of the proposed issuance of such New Securities an “accredited investor” as such term is defined in Regulation D under the Securities Act. Each Major Investor shall be entitled to assign or apportion the right of first offer hereby granted it among itself and its Affiliates (as defined in Section 6.6 below) in such proportions as it deems appropriate. A Major Investor’s “Pro Rata Share” for purposes of this right of first refusal is the ratio of (a) the number of Registrable Securities as to which such Major Investor is the Holder (and/or is deemed to be the Holder under Section 2.1(b)), to (b) a number of shares of Class A Common Stock of the Company equal to the sum of (1) the total number of shares of Class A Common Stock of the Company then outstanding, including all outstanding options, warrants and other securities exercisable for or convertible into Class A Common Stock, plus (2) the total number of shares of Class A Common Stock of the Company into which all then outstanding shares of Preferred Stock are then convertible, including all outstanding options, warrants and other securities exercisable for or convertible into Preferred Stock.

3.2    New Securities. “New Securities” shall mean any Common Stock, preferred stock or other security of the Company, whether now authorized or not, and rights, options or warrants to purchase such Common Stock, preferred stock or other security, and securities of any type whatsoever that are, or may become, convertible or exchangeable into such Common Stock, preferred stock or other security; provided, however, that the term “New Securities” does not include any securities excluded from the definition of “Additional Shares of Common Stock” under Section 6.8(b)(i) of the Restated Certificate.

3.3    Procedures. In the event that the Company proposes to undertake an issuance of New Securities, it shall give to each Major Investor a written notice of its intention to issue New Securities (the “Notice”), describing the type of New Securities and the price and the general terms upon which the Company proposes to issue such New Securities given in accordance with Section 6.1 hereof. Each Major Investor shall have twenty (20) days from delivery of such Notice to agree in writing to purchase such Major Investor’s Pro Rata Share of such New Securities for the price and upon the general terms specified in the Notice by giving written notice to the Company and stating therein the quantity of New Securities to be purchased (not to exceed such Major Investor’s Pro Rata Share). If any Major Investor fails to so agree in writing within such twenty (20) day period to purchase such Major Investor’s full Pro Rata Share of an offering of New Securities (a “Nonpurchasing Holder”), then such Nonpurchasing Holder shall forfeit the right hereunder to purchase that part of his, her or its Pro Rata Share of such New Securities that he, she or it did not so agree to purchase. The Company shall promptly notify in writing the Major Investors who did so elect to purchase such Major Investors’ Pro Rata Share of such New Securities (the “Participating Major Investors”) and shall offer such Participating Major Investors the right to acquire such unsubscribed shares of New Securities. The Participating Major

14

Investors shall have ten (10) days after receipt of such notice to notify the Company of its election to purchase all or a portion thereof of the unsubscribed shares of such New Securities. In the event that the Participating Major Investors desire, in the aggregate, to purchase in excess of the total number of unsubscribed shares of such New Securities, then the number of unsubscribed shares that each Participating Major Investor may purchase shall be reduced on a pro rata basis.

3.4    Failure to Exercise. In the event that the Major Investors fail to exercise in full the right of first refusal within such original twenty (20) day period plus the ten (10) day period for the right of overallotment, then the Company shall have ninety (90) days thereafter to sell the New Securities with respect to which the Major Investors’ rights of first refusal hereunder were not exercised, at a price and upon general terms not materially more favorable to the purchasers thereof than specified in the Notice. In the event that the Company has not issued and sold the New Securities within such ninety (90) day period, then the Company shall not thereafter issue or sell any New Securities without again first offering such New Securities to the Major Investors pursuant to this Section 3.

3.5    Termination. This right of first refusal shall terminate upon the earlier of (a) the closing of a Qualified IPO or (b) a Deemed Liquidation Event.

3.6    Alternate Procedure. Notwithstanding any provision hereof to the contrary, in lieu of complying with the provisions of Section 3.3, the Company may elect to give notice to the Major Investors within thirty (30) days after the issuance of New Securities. Such notice shall describe the type, price, and terms of the New Securities, and the identities of the Persons (as defined below) to whom the New Securities were sold. Each Major Investor shall have twenty (20) days after the date the Company’s notice is given to elect, by giving notice to the Company, to purchase up to the number of New Securities that such Major Investor would otherwise have the right to purchase pursuant to Section 3.1 above had the Company complied with the provisions of Section 3.3 in connection with the issuance of such New Securities under the terms and conditions set forth in the Company’s notice pursuant to this Section 3.6. Any Major Investors electing to purchase such New Securities shall also have rights of oversubscription to purchase New Securities that were purchasable by other Major Investors pursuant to the foregoing sentence but were not so purchased, and such rights of oversubscription shall be apportioned in a manner consistent with the apportionment among Purchasing Holders described in Section 3.3. The closing of such sale shall occur within sixty (60) days of the date notice is given to the Major Investors.

4.    ASSIGNMENT AND AMENDMENT.

4.1    Assignment. Notwithstanding anything herein to the contrary:

(a)    Information Rights; Rights of First Refusal.

(b)    Registration Rights. The registration rights of a Holder under Section 2 hereof may be assigned only to (i) a partner, Affiliate or shareholder of an Investor or (ii) a party who acquires at least 50,000 shares of Registrable Securities and/or an equivalent number (on an as-converted basis) of Registrable Securities, issued upon conversion thereof; provided, however that no party may be assigned any of the foregoing rights unless the Company is given written notice by the assigning party stating the name and address of the assignee and identifying the securities of the Company as to which the rights in question are being assigned; provided, further, that any such assignee shall receive such assigned rights subject to all the terms and conditions of this Agreement, including without limitation the provisions of this Section 4.
