WHEREAS, the Existing Investors as holders of more than sixty percent (60%) of (i) the Senior Registrable Securities, and (ii) the Senior Registrable Securities held by Significant Holders (as such terms are defined in the Prior Agreement) desire to amend and restate the Prior Agreement and to accept the rights created pursuant hereto in lieu of the rights granted to them under the Prior Agreement; and

NOW, THEREFORE, in consideration of the mutual promises and covenants set forth herein, the parties hereto agree as follows:

1. Restrictions on Transferability of Securities; Registration Rights.

1.1 Restrictions on Transfer.

(a) Holding Securities. Each Holder agrees not to make any disposition of all or any portion of the Senior Registrable Securities unless and until the transferee has agreed in writing for the benefit of the Company to be bound by this Section 1.1, provided and to the extent such Section 1.1 is then applicable, and:

(i) There is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement; or

(ii) Such Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and, if reasonably requested by the Company, such Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of such shares under the Securities Act. It is agreed that the Company will not require opinions of counsel for transactions made pursuant to Rule 144 except in unusual circumstances.

(iii) Notwithstanding the provisions of paragraphs (i) and (ii) above, no such registration statement or opinion of counsel shall be necessary for a transfer by a Holder to an Affiliate of such Holder, or by a Holder which is (A) a partnership to its partners or retired partners in accordance with partnership interests, (B) a corporation to its stockholders in accordance with their interest in the corporation, (C) a limited liability company to its members or former members in accordance with their interest in the limited liability company, (D) an investment or venture capital fund to an affiliated investment or venture capital fund or (E) to the Holder’s family member or trust for the benefit of an individual Holder, provided in any such case that the transfer complies with applicable securities laws and the transferee will be subject to the terms of this Section 1.1 to the same extent as if such transferee were an original Holder hereunder.

(b) Legends. Each certificate representing Registrable Securities shall (unless otherwise permitted by the provisions of this Agreement) be stamped or otherwise imprinted with a legend substantially similar to the following (in addition to any legend required under applicable state securities laws):

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT.

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A LOCK-UP PERIOD OF UP TO 214 DAYS FOLLOWING THE EFFECTIVE DATE OF A REGISTRATION STATEMENT OF THE COMPANY FILED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AS SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE COMPANY. SUCH LOCK-UP PERIOD IS BINDING ON TRANSFEREES OF THESE SHARES.

(c) Unlegended Certificates. The Company shall be obligated to reissue unlegended certificates at the request of any holder thereof if the holder shall have obtained (i) an opinion of counsel at such Holder’s expense (which counsel may be counsel to the Company) reasonably acceptable to the Company to the effect that the securities proposed to be disposed of may lawfully be so disposed of without registration, qualification or legend, and (ii) delivered such securities to the Company or its transfer agent. The Company shall use commercially reasonable efforts to deliver, or cause its transfer agent to deliver, such unlegended certificates no later than five business days after the request thereof that meets the foregoing requirements.

(d) Endorsement. Any legend endorsed on an instrument pursuant to applicable state securities laws and the stop-transfer instructions with respect to such securities shall be removed upon receipt by the Company of an order of the appropriate blue sky authority authorizing such removal.

1.2 Requested Registration of Senior Registrable Securities.

(a) Request. If the Company shall receive from a class of Initiating Holders at any time or times not earlier than the earlier of (i) three (3) years after the date of this Agreement or (ii) six (6) months after the effective date of a public offering involving an underwriting with aggregate proceeds (before deduction of any underwriting discounts and commissions) in excess of $50,000,000 (a “Qualified Public Offering”), a written request that the Company effect any registration with respect to all or a part of such class of the Senior Registrable Securities having reasonably anticipated aggregate proceeds which (after deduction for underwriter’s discounts and expenses related to the issuance) exceed $30,000,000, the Company will:

(i) promptly, and in any event within twenty (20) days of the receipt of such request, give written notice of the proposed registration to all other Holders; and

(ii) as soon as practicable, use its best efforts to effect such registration (including, without limitation, filing post-effective amendments, appropriate qualifications under applicable blue sky or other state securities laws, and appropriate compliance with the Securities Act) and as would permit or facilitate the sale and distribution of all or such portion of such Senior Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any Holder or Holders joining in such request as are specified in a written request received by the Company within thirty (30) days after such written notice from the Company is mailed or delivered. Notwithstanding anything to the contrary contained herein, if the registration requested is to be an underwritten offering and if the underwriters have not limited the number of Registrable Securities to be underwritten, the Company shall be entitled, at its election, to join in any such registration with respect to securities to be offered by it or any other party.

The Company shall not be obligated to effect, or to take any action to effect, any such registration pursuant to this Section 1.2:

(A) In any particular jurisdiction in which the Company would be required 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;

(B) With respect to a particular class of Initiating Holders, after the Company has initiated two such registrations pursuant to this Section 1.2(a) for such class of Initiating Holders (counting for these purposes only registrations which have been declared or ordered effective and pursuant to which securities have been sold and registrations which have been withdrawn by the Holders for any reason (other than an adverse change in the circumstances regarding the Company) as to which the Holders have not elected to bear the Registration Expenses pursuant to Section 1.4 hereof);

(C) During the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of filing of, and ending on a date one hundred eighty (180) days after the effective date of, a Company-initiated registration; provided, that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to become effective provided that the Company shall not defer its obligations in this Section 1.2 more than once in any twelve (12) month period; or

(D) If the Initiating Holders propose to dispose of shares of Senior Registrable Securities which may be immediately registered on Form S-3 pursuant to a request made under Section 1.5 hereof.

(b) Filing of Registration Statement. Subject to the foregoing clauses (a)(ii)(A) through (D), the Company shall file a registration statement covering the Registrable Securities so requested to be registered as soon as practicable after receipt of the request or requests of any class of Initiating Holders; provided, however, that if (i) in the good faith judgment of the Board of Directors of the Company (the “Board”), such registration would be detrimental to the Company and the Board concludes, as a result, that it is in the best interests of the Company to defer the filing of such registration statement at such time, and (ii) the Company shall furnish to such Holders a certificate signed by the President of the Company stating that in the good faith judgment of the Board, it would be detrimental to the Company for such registration statement to be filed in the near future and that it is, therefore, in the best interests of the Company 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 eighty (180) days on a cumulative basis after receipt of the request of any class of Initiating Holders, and, provided further, that the Company shall not defer its obligation in this manner more than once in any twelve (12) month period and provided further that the Company shall not register any securities for the account of itself or any other stockholder during such one hundred eighty (180) day period (other than a registration relating solely to the sale of securities of participants in a Company stock plan, a registration relating to a corporate reorganization or transaction under Rule 145 of the Securities Act, a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities, or a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt securities that are also being registered).

The registration statement filed pursuant to the request of any class of Initiating Holders may, subject to the provisions of Sections 1.2(d) and 1.13 hereof, include other securities of the Company, with respect to which registration rights have been granted, and may include securities of the Company being sold for the account of the Company.

(c) Underwriting. The right of any Holder to registration pursuant to Section 1.2, if the proposed registration is for an underwritten offering (in which case the Company shall include such information in the written notice specified in Section 1.2(a)(i)), shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the applicable class of Initiating Holders and such Holder with respect to such participation and inclusion) to the extent provided herein. A Holder may elect to include in such underwriting all or a part of the Registrable Securities he holds.

(d) Procedures. If JVB Properties, L.L.L.P. (“JVB”) shall request inclusion of any JVB Shares in any registration pursuant to Section 1.2, or if the Company shall request inclusion in any registration pursuant to Section 1.2 of securities being sold for its own account, or if persons other than Investors, JVB or ▇▇▇▇▇ shall request inclusion in any registration pursuant to Section 1.2, the applicable class of Initiating Holders shall, on behalf of all Holders, offer to include such securities in the registration and may condition such offer on their acceptance of the further applicable provisions of this Section 1 (including Section 1.13). If the proposed registration is for an underwritten offering, the Company shall (together with all Holders and other persons proposing to distribute their securities through such underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected for such underwriting by a majority in interest of the applicable class of Initiating Holders, which underwriters are reasonably acceptable to the Company. Notwithstanding any other provision of this Section 1.2, if the representative of the underwriters advises the applicable class of Initiating Holders in writing that marketing factors require a limitation on the number of shares to be underwritten, the number of shares to be included in the underwriting or registration shall be allocated as set forth in Section 1.14 hereof. If a person who has requested inclusion in such registration as provided above does not agree to the terms of any such underwriting, such person shall be excluded therefrom by written notice from the Company, the underwriter or the applicable class of Initiating Holders. The securities so excluded shall also be withdrawn from registration. If shares are so withdrawn from the registration and if the number of shares to be included in such registration was previously reduced as a result of marketing factors, then the Company shall offer to all holders who have retained rights to include securities in the registration the right to include additional securities in the registration in an aggregate amount equal to the number of shares so withdrawn, with such shares to be allocated among such Holders requesting additional inclusion in accordance with Section 1.14 hereof.

1.3 Company Registration.

(a) Company Obligations. If the Company shall determine to register any of its securities either for its own account or the account of a security holder or holders exercising their respective demand registration rights (other than pursuant to Section 1.2 or 1.5 hereof), other than a registration relating solely to employee benefit plans, a registration relating solely to

the offer and sale of debt securities, or a registration relating to a corporate reorganization or other transaction on Form S-4, or a registration on any registration form that does not permit secondary sales (which the Company will not willfully seek to avail for the purpose of avoiding its obligations under this Section 1.3), the Company will:

(i) promptly give to each Holder written notice thereof; and

(ii) use its best efforts to include in such registration (and any related qualification under blue sky laws or other compliance), except as set forth in Section 1.3(b) below, and in any underwriting involved therein, all the Registrable Securities specified in a written request or requests, made by any Holder and received by the Company within thirty (30) days after the written notice from the Company described in clause (i) above is mailed or delivered by the Company. Such written request may specify all or a part of a Holder’s Registrable Securities.

(b) Underwriting. If the registration of which the Company gives notice is for a registered public offering of any of its securities to the general public involving an underwriting of shares of the Company’s capital stock, the Company shall so advise the Holders as a part of the written notice given pursuant to Section 1.3(a)(i). In such event, the right of any Holder to registration pursuant to this Section 1.3 shall be conditioned upon such Holder’s participation in such underwriting on such customary terms as agreed upon between the Company and the underwriters selected by the Company 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 and the other holders of securities of the Company with registration rights to participate therein distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected by the Company.

Notwithstanding any other provision of this Section 1.3, if the representative of the underwriters advises the Company in writing that marketing factors require a limitation on the number of shares to be underwritten, the representative may (subject to the limitations set forth below) exclude all Registrable Securities from, or limit the number of Registrable Securities to be included in, the registration and underwriting. In no event shall any Senior Registrable Securities be excluded from such offering unless all other stockholders’ securities have been first excluded, including without limitation JVB Shares. The Company shall so advise all holders of securities requesting registration, and the number of shares of securities that are entitled to be included in the registration and underwriting shall be allocated first to the Company for securities being sold for its own account and thereafter as set forth in Section 1.14. If any person does not agree to the terms of any such underwriting, he shall be excluded therefrom by written notice from the Company or the underwriter. Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall be withdrawn from such registration. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriter(s) may round the number of shares allocated to any Holder to the nearest 100 shares. Notwithstanding any other provision hereof, the amount of Senior Registrable Securities of the selling Holders included in the registration shall not be reduced below thirty percent (30%) of the total amount of securities included in such registration, unless such offering is the Company’s

initial public offering in which event any or all of the Registrable Securities may be excluded in accordance with this Section 1.3(b) if the underwriters make the determination described above and no other stockholder’s securities are included in such offering. For purposes of this section, for any selling stockholder that is a Holder of Registrable Securities and that is an investment or venture capital fund, partnership or corporation, the affiliated investment or venture capital funds, 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 “selling Holder,” and any pro rata reduction with respect to such “selling Holder” shall be based upon the aggregate amount of Registrable Securities owned by all such related entities and individuals.

If shares are so withdrawn from the registration and if the number of shares of Registrable Securities to be included in such registration was previously reduced as a result of marketing factors, the Company shall then offer to all persons who have retained the right to include securities in the registration the right to include additional securities in the registration in an aggregate amount equal to the number of shares so withdrawn, with such shares to be allocated among the persons requesting additional inclusion in accordance with Section 1.14 hereof.

(c) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 1.3 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration. The expenses of such withdrawn registration shall be borne by the Company in accordance with Section 1.4 hereof.

1.4 Expenses of Registration. All Registration Expenses incurred in connection with any registration, qualification or compliance pursuant to Sections 1.2, 1.3 and 1.5 hereof and reasonable fees of one counsel for the selling stockholders in the case of registrations pursuant to Sections 1.2, 1.3 and 1.5 shall be borne by the Company. Notwithstanding the foregoing, the Company shall not be required to pay for any Registration Expenses of any registration, qualification or compliance pursuant to Sections 1.2 or 1.5 if the registration request is subsequently withdrawn at the request of Initiating Holders of a majority of the class of Registrable Securities to be registered or Holders of a majority of the Registrable Securities to be registered, respectively, unless the Initiating Holders of a majority of the class of Registrable Securities then outstanding agree to forfeit their right to one demand registration pursuant to Section 1.2 (in which case such right shall be forfeited by all Holders of such class of Registrable Securities). All Selling Expenses relating to securities so sold shall be borne by each holder of such securities pro rata on the basis of the number of shares of securities so sold on its behalf.

1.5 Registration on Form S-3. After its initial public offering, the Company shall use its best efforts to qualify for registration on Form S-3 or any comparable or successor form or forms. After the Company has qualified for the use of Form S-3, in addition to the rights contained in the foregoing provisions of this Section 1, all Holders of at least 5% of the Senior Registrable Securities shall have the right to request registrations on Form S-3 (such requests shall be in writing and shall state the number of shares of Senior Registrable Securities to be disposed of and the intended methods of disposition of such shares by such Holder or Holders); provided, however, that the Company shall not be obligated to effect any such registration (i) 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) on Form S-3 at an aggregate price to the public reasonably anticipated to be less than $30,000,000 (ii) in the circumstances described in clauses (A) and (C) of Section 1.2(a)(ii) (but not paragraphs (B) or (D) thereof), (iii) if the Company shall furnish the certification described in Section 1.2(b) (but subject to the limitations set forth therein), or (iv) if, in a given twelve-month period, the Company has effected two (2) such registrations in such period.

If a request complying with the requirements of this Section 1.5 is delivered to the Company, the provisions of Sections 1.2(a)(i) and (ii) and Section 1.2(b) hereof shall apply to such registration. If the registration is for an underwritten offering, the provisions of Sections 1.2(c) and 1.2(d) hereof shall apply to such registration.

1.6 Demand Registration of JVB Shares. At any time that there are no outstanding Senior Registrable Securities, or with the consent of the Holders of all outstanding Senior Registrable Securities, JVB may make a written request to the Company for a registration under Section 1.2 as if JVB were the Initiating Holders or under Section 1.5 as if JVB were the Holders of at least 5% of the Senior Registrable Securities; provided, that, the Company shall not be obligated to comply with the provisions of those sections to the extent of any limitations or prohibitions contained in any other agreement to which the Company is subject at the time such request is made by JVB. In each case, JVB will be subject to the same requirements as the Initiating Holders in the case of a request under Section 1.2 and the requesting Holders in the case of a request under Section 1.5.

1.7 Registration Procedures. In the case of each registration effected by the Company pursuant to Section 1 that includes Registrable Securities, the Company will keep each Holder advised in writing as to the initiation of each registration and as to the completion thereof. At its expense, the Company shall, as expeditiously as reasonably possible:

(a) Prepare and file with the Commission a registration with respect to such Registrable Securities and use all commercially reasonable efforts to cause such registration statement to become effective, and keep such registration effective for a period of one hundred and twenty (120) days or until the Holder or Holders have completed the distribution described in the registration statement relating thereto, whichever first occurs;

(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 such number of prospectuses and other documents incident thereto, including any amendment of or supplement to the prospectus, as a Holder from time to time may reasonably request together with a legal opinion in customary form as to the due authorization and valid issuance of the Registrable Securities and such other matters as are customarily included in an opinion to underwriters;

(d) Use all commercially reasonable efforts to cause all such Registrable Securities registered pursuant hereunder to be listed on a national exchange or trading system and on each securities exchange and trading system on which similar securities issued by the Company are then listed;

(e) Use all 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;

(f) In connection with any underwritten offering pursuant to such registration statement, the Company will enter into an underwriting agreement in form reasonably necessary to effect the offer and sale of Common Stock, provided such underwriting agreement contains reasonable and customary provisions;

(g) 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;

(h) Provide the underwriters and prospective purchasers in connection with such offer and sale of the Registrable Securities with a reasonable opportunity in which to undertake a due diligence investigation with respect to the Company and to make available appropriate officers of the Company for a reasonable number of customary “road shows;” and

(i) 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.

1.8 Indemnification.

(a) Company Indemnification. The Company will indemnify each Holder, each of its officers, directors and partners, legal counsel, and accountants and each person controlling such Holder within the meaning of the Securities Act or the Exchange Act, with respect to which registration, qualification, or compliance has been effected pursuant to this Section 1, and each underwriter, if any, and each person who controls within the meaning of the Securities Act or Exchange Act any underwriter, against all expenses, claims, losses, damages, and liabilities, joint or several (or actions, proceedings, or settlements in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus, offering circular, or other document (including any related registration statement, notification, or the like) incident to any such registration, qualification, or compliance, or based on 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, or any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities

laws, or any rule or regulation thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification, or compliance, and will reimburse each such Holder, each of its officers, directors, partners, legal counsel, and accountants and each person controlling such Holder, each such underwriter, and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating and defending or settling any such claim, loss, damage, liability, or action, provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability, or expense arises out of or is based on any untrue statement or omission based upon written information furnished to the Company by such Holder or underwriter and stated to be specifically for use therein. It is agreed that the indemnity agreement contained in this Section 1.8(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).

(b) Holder Indemnification. Each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration, qualification, or compliance is being effected, indemnify the Company, each of its directors, officers, partners, legal counsel, and accountants and each underwriter, if any, of the Company’s securities covered by such a registration statement, each person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act, each other such Holder and Other Stockholder, and each of their officers, directors, and partners, and each person controlling such Holder or Other Stockholder, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular, or other document, 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, and will reimburse the Company and such Holders, Other Stockholders, directors, officers, partners, legal counsel, and accountants, persons, underwriters, or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, 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) is made in such registration statement, prospectus, offering circular, or other document in reliance upon and in conformity with written information furnished to the Company by such Holder and stated to be specifically for use therein provided, however, that the obligations of such Holder hereunder shall not apply to amounts paid in settlement of any such claims, losses, damages, or liabilities (or actions in respect thereof) if such settlement is effected without the consent of such Holder (which consent shall not be unreasonably withheld); and provided that in no event shall any indemnity under this Section 1.8 exceed the net proceeds from the offering received by such Holder.

(c) Procedure. Each party entitled to indemnification under this Section 1.8 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld), and the Indemnified Party may participate in such defense at such

party’s expense, and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 1, to the extent such failure is not prejudicial. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. Each Indemnified Party shall furnish such information regarding itself or the claim in question as an Indemnifying Party may reasonably request in writing and as shall be reasonably required in connection with defense of such claim and litigation resulting therefrom.

(d) Relative Fault. If the indemnification provided for in this Section 1.8 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 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, 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; provided, however, that no contribution by any Holder, when combined with any amounts paid by such Holder pursuant to Section 1.8(b), shall exceed the net proceeds from the offering received by such Holder. 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.

(e) 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 shall control; provided, however, in no event shall such Holders be obligated to indemnify prospective purchasers for any matter which the Company is obligated to indemnify such purchasers under Section 1.8(a) above.

(f) Survival. The obligations of the Company and Holders under this Section 1.8 shall survive the completion of any offering of Registrable Securities in a registration statement under this Section 1 and otherwise.

1.9 Information by Holder. Each Holder of Registrable Securities shall promptly furnish to the Company all necessary information regarding such Holder and the distribution proposed by such Holder as the Company, the underwriters to such registration or the Company’s transfer agent may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification, or compliance referred to in this Section 1.

1.10 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 60% of

the Senior Registrable Securities, enter into any agreement with any holder or prospective holder of any securities of the Company giving such holder or prospective holder any registration rights the terms of which are not subordinate to the registration rights granted to the Holders of Senior Registrable Securities hereunder. JVB acknowledges that the Company may enter into agreements that would give such holder or prospective holders registrations rights that are not subordinate to the registration rights granted hereunder with respect to the JVB Shares.

1.11 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Restricted Securities to the public without registration, or pursuant to a registration on Form S-3, the Company agrees to use its commercially reasonable efforts to:

(a) 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;

(b) So long as a Holder owns any Restricted Securities, furnish to the Holder forthwith upon written request a written statement by the Company as to its compliance with the reporting requirements of Rule 144 (at any time from and after ninety (90) days following 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 such reporting requirements), a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed 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; and

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 34 days if the Company issues or proposes to issue an earnings or other public release within 18 days of the expiration of the 180-day lockup 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 Common Stock, or any securities convertible into or exercisable or exchangeable (directly or indirectly) for Common Stock, held immediately before the effective date of the registration statement for the IPO 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 such securities, whether any such transaction described in clause (a) or (b) above is to be settled by delivery of Common Stock or other securities, in cash, or otherwise.

1.14 Allocation of Registration Opportunities. Except as otherwise stated herein, in any circumstance in which all of the Registrable Securities and other shares of Common Stock of the Company (including shares of Common Stock issuable or issued upon conversion of shares of any currently unissued series of Preferred Stock of the Company) with registration rights (the “Other Shares”) requested to be included in a registration on behalf of the Holders or other selling stockholders cannot be so included as a result of limitations imposed upon shares to be underwritten of the aggregate number of shares of Registrable Securities and Other Shares that may be so included, the number of shares of Registrable Securities and Other Shares that may be so included shall be allocated among the Holders and other selling stockholders requesting inclusion of shares pro rata on the basis of the number of shares of Registrable Securities and Other Shares that would be held by such Holders and other selling stockholders proposed to be included in such registration, assuming conversion; provided, however, that such allocation shall not operate to reduce the aggregate number of Registrable Securities and Other Shares to be included in such registration, if any Holder or other selling stockholder does not request inclusion of the maximum number of shares of Registrable Securities and Other Shares allocated to him pursuant to the above-described procedure, in which case the remaining portion of his allocation shall be reallocated among those requesting Holders and other selling stockholders whose allocations did not satisfy their requests pro rata on the basis of the number of shares of Registrable Securities and Other Shares which would be held by such Holders and other selling

stockholders, assuming conversion, and this procedure shall be repeated until all of the shares of Registrable Securities and Other Shares which may be included in the registration on behalf of the Holders and other selling stockholders have been so allocated. Notwithstanding the foregoing, the Company shall not limit the number of Senior Registrable Securities to be included in a registration pursuant to this Agreement in order to include any JVB Shares or shares held by stockholders with no registration rights or to include shares of stock issued to any person other than the Holders or to employees, officers, directors, or consultants pursuant to the any equity incentive plan of the Company, or in the case of registrations under Sections 1.2 or 1.5 hereof, in order to include in such registration securities registered for the Company’s own account; provided, that in the case of a registration initiated by a class of Initiating Holders under Section 1.2, no Registrable Securities that are not in or held upon conversion of the applicable class of Senior Registrable Securities associated with the Initiating Holders shall be included in such registration prior to the inclusion in full of any Senior Registrable Securities of or held upon conversion of such class requested to be included in such registration.

1.15 Delay of Registration. No Holder shall have any right to take any action to restrain, enjoin, or otherwise delay any registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 1.

1.16 Termination of Registration Rights. The right of any Holder to request registration or inclusion in any registration pursuant to Section 1.2, 1.3 or 1.5 shall terminate on the earlier of (i) such date after the closing of the first registered public offering of Common Stock of the Company as all shares of Registrable Securities held or entitled to be held upon conversion by such Holder (together with any affiliate of the Holder with whom such Holder must aggregate its sales under Rule 144) may immediately be sold under Rule 144 during any three month period, and (ii) four (4) years after the closing of the Qualified Public Offering.

under this paragraph will be to deliver the audited financial statements for such fiscal year promptly after the same become available from the Company’s auditors; and

(b) Inspection Rights. The Company will afford to each Significant Holder and to such Significant Holder’s accountants and legal counsel, reasonable access during normal business hours to all of the Company’s respective properties, books and records. Each Holder shall have such other access to management and information as is necessary for it to comply with applicable laws and regulations and reporting obligations. The Company shall not be required to disclose details of contracts with or work performed for specific customers and other business partners where to do so would violate confidentiality obligations to those parties. Holders may exercise their rights under this Section 2.1(b) only for purposes reasonably related to their interests under this Agreement and related agreements.

2.2 Termination of Covenants. The covenants set forth in this Section 2 shall terminate and be of no further force and effect after the closing of an IPO.

3.1 Right of First Refusal to Significant Holders. Subject to subsection (f) hereof, the Company hereby grants to each Significant Holder, the right of first refusal (the “Right of

First Refusal”) to purchase a Pro Rata Share of New Securities (as defined in this Section 3.1) which the Company may, from time to time, propose to sell and issue. For purposes of this Section 3, “Pro Rata Share” shall mean the ratio of the number of shares of Common Stock issued or issuable upon conversion of the Shares owned by such Significant Holder immediately prior to the issuance of New Securities, to the total number of shares of Common Stock outstanding immediately prior to the issuance of New Securities, assuming: (i) full conversion of the Shares; and (ii) exercise and conversion of all outstanding convertible securities, rights, options and warrants to acquire Common Stock of the Company. For purposes of this Section 3, the term “Significant Holder” includes any general partners and affiliates of a Significant Holder. A Significant Holder shall be entitled to apportion the right of first refusal hereby granted it among itself and its partners and affiliates in such proportions as it deems appropriate. Each Significant Holder shall have a right of over-allotment such that if any Significant Holder fails to exercise its right hereunder to purchase its Pro Rata share of New Securities, the other Significant Holders may purchase the non-purchasing Significant Holder’s portion on a pro rata basis within twenty (20) days from the date the Company provides such Significant Holder written notice of such non-purchasing Significant Holder fails to exercise its right hereunder to purchase its Pro Rata share of New Securities. This right of first refusal shall be subject to the following provisions:

(a) New Securities. “New Securities” shall mean any capital stock (including Common Stock and/or Preferred Stock) of the Company whether now authorized or not, and rights, options or warrants to purchase such capital stock, and securities of any type whatsoever that are, or may become, convertible into capital stock; provided that the term “New Securities” does not include the securities excluded from the definition of “Additional Shares” under Article IV, Section 4.2.5.4.1(d) of the Company’s Seventh Restated Certificate of Incorporation, as the same may be amended from time to time (the “Restated Certificate”).

(b) Notice. In the event the Company proposes to undertake an issuance of New Securities, it shall give each Significant Holder written notice of its intention, describing the type of New Securities, and their price and the general terms upon which the Company proposes to issue the same. Each Significant Holder shall have thirty (30) days after any such notice is mailed or delivered to agree to purchase such Holder’s Pro Rata share of such New Securities for the price and upon the terms specified in the notice by giving written notice to the Company and stating therein the quantity of New Securities to be purchased.

(c) Overallotment. In the event the Holders fail to exercise fully the right of first refusal as provided in Section 3.1 hereof, and after the expiration of the over-allotment exercise period set forth in Section 3.1 hereof, the Company shall have ninety (90) days thereafter to sell or enter into an agreement to sell the New Securities respecting which the Significant Holders’ right of first refusal option set forth in this Section 3.1 was not exercised, at a price and upon terms no more favorable to the purchasers thereof than specified in the Company’s notice to Significant Holders pursuant to Section 3.1(b). In the event the Company has not entered into an agreement for the sale of the New Securities within such ninety (90) day period, or if such sale is not consummated within sixty (60) days from the date of said agreement, the Company shall not thereafter issue or sell any New Securities, without first again offering such securities to the Significant Holders in the manner provided in this Section 3.1.

(d) Termination of Rights. The rights set forth in this Section 3 shall terminate and be of no further force and effect after the closing of an IPO.

(e) Assignment. The right of first refusal set forth in this Section 3.1 may not be assigned or transferred, except that (i) a Significant Holder that is an investment or venture capital fund may assign or transfer such rights to an affiliated investment or venture capital fund, (ii) such right is assignable by each Holder to any wholly owned subsidiary or parent of, or to any corporation, entity or person that is, within the meaning of the Securities Act, controlling, controlled by or under common control with, any such Holder, (iii) such right is assignable between and among any of the Holders, and (iv) with the prior written consent of the Company not to be unreasonably withheld.

Pursuant to Section 4.2 of the Prior Agreement, the undersigned parties who are parties to the Prior Agreement hereby amend and restate the Prior Agreement to read in its entirety as set forth in this Agreement, such that the Prior Agreement is hereby terminated and entirely replaced and superseded by this Agreement.

The parties will cooperate with JAMS and with each other in promptly selecting an arbitrator from JAMS’ panel of neutrals, and in scheduling the arbitration proceedings in order to fulfill the provisions, purposes and intent of this Agreement. If no agreement as to selection of an arbitrator can be reached within thirty (30) days after delivery of the written demand for arbitration, then each party shall select an arbitrator and such selected arbitrators shall jointly agree on a third arbitrator. The three arbitrators shall act as a panel of arbitrators and rule by majority.

Anything in this Agreement to the contrary notwithstanding, no Holder by reason of this Agreement shall have access to any trade secrets or classified information of the Company. The Company shall not be required to comply with any information rights of Section 2 in respect of any Holder whom the Company reasonably determines to be a competitor or an officer, employee, or director of a competitor. Each Holder acknowledges that the information received by them pursuant to Section 2 of this Agreement is confidential and for its use only, and it will not use such confidential information in violation of the Exchange Act or reproduce, disclose or disseminate such information to any other person (other than its employees or agents having a need to know the contents of such information, and

its attorneys), without the Company’s consent, except in connection with the exercise of rights under this Agreement, unless the Company has made such information available to the public generally or such Holder is required to disclose such information by a governmental authority; provided, however, that a Holder may disclose confidential information (i) to its attorneys, accountants, consultants, and other professionals to the extent reasonably necessary; (ii) to any prospective purchaser of any Registrable Securities from such Holder, if prior to disclosure such prospective purchaser agrees with the Company in writing to be bound by the provisions of this Section 4.14 and such prospective purchaser is not a competitor of the Company or an officer, employee, or director of a competitor, as determined by the Company; (iii) to any affiliate, partner, member, stockholder, or wholly owned subsidiary of such Holder in the ordinary course of business, or (iv) as may otherwise be required by law, provided that the Investor promptly notifies the Company of such disclosure and takes reasonable steps to minimize the extent of any such required disclosure; provided, further, that notwithstanding the foregoing, a Holder may include summary financial information concerning the Company and general statements concerning the nature and progress of the Company’s business in its reports to its limited partners and affiliates.

4.15 Termination Upon Change of Control. This Agreement (excluding any then-existing obligations) shall terminate upon the closing of a Change of Control Transaction as defined below. Notwithstanding the foregoing, the Company will use all commercially reasonable efforts to cause any such successor entity to assume the registration and other rights granted hereby to the extent equivalent liquidity and such other rights would otherwise be unavailable to the Holders of such successor entity. A “Change of Control Transaction” shall mean: (a) the consummation of the acquisition of the Company by another entity or merger or consolidation of the Company with or into another entity by means of any transaction or series of related transactions (except a transaction or series of transactions in which the holders of capital stock of the Company immediately prior to such merger or consolidation continue to hold at least 50% of the voting power of the capital stock of the Company or the surviving or acquiring entity); or (B) a sale, other transfer, or exclusive license that constitutes the effective disposition of all or substantially all of the assets of the Company, including a sale or other transfer of all or substantially all of the assets of the Company’s subsidiaries, if such assets constitute substantially all of the assets of the Company and such subsidiaries taken as a whole, provided, that, for clarity, a license that is exclusive as to a particular territory or market shall not be a Change of Control Transaction unless such license otherwise constitutes an effective disposition of all or substantially all of the assets of the Company.

4.16 Expenses.
