Subject to the conditions set forth in this Section 2.1, if the Company shall receive from Initiating Holders a written request signed by such Initiating Holders that the Company effect any registration with respect to all or a part of the Registrable Securities (such request shall state the number of shares of Registrable Securities proposed to be disposed of by such Initiating Holders), the Company will:

(i) promptly give written notice of the proposed registration to all other Holders; and

(ii) as soon as practicable, but in any event within ninety (90) days after the Company’s receipt of such written request, file and use its commercially reasonable 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 to permit or facilitate the sale and distribution of all or such portion of such 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.

(b) Limitations on Requested Registration. The Company shall not be obligated to effect, or to take any action to effect, any such registration pursuant to this Section 2.1:

(i) Prior to the earlier of (A) the three (3) year anniversary of the date of this Agreement or (B) six (6) months following the effective date of the first registration statement filed by the Company covering an underwritten offering of any of its securities to the general public (or the subsequent date on which all market stand-off agreements applicable to the offering have terminated, not to exceed an additional thirty-four (34) days);

(ii) If the Company has not yet offered securities pursuant to a registration statement and the Initiating Holders propose to sell less than 20% of the Registrable Securities held by such Initiating Holders unless such lesser number of Registrable Securities proposed to be sold by the Initiating Holders is expected to result in aggregate net proceeds (after deduction for underwriter’s discounts and expenses related to the issuance) greater than $20,000,000 (or if after the Initial Public Offering, Registrable Securities with an anticipated aggregate offering price of at least $5,000,000);

(iii) 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;

(iv) After the Company has initiated two (2) such registrations pursuant to this Section 2.1 (counting for these purposes only (x) registrations which have been declared or ordered effective and pursuant to which securities have been sold, and (y) Withdrawn Registrations);

(v) During the period that is thirty (30) days prior to the Company’s good faith estimate of the date of filing of, and ending on a date ninety (90) days (or one hundred eighty (180) days, in the case of an Initial Public Offering) after the effective date of a Company-initiated registration (or ending on the subsequent date on which all market stand-off agreements applicable to the offering have terminated, not to exceed an additional thirty-four (34) days); provided that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to become effective;

(vi) If the Initiating Holders propose to dispose of shares of Registrable Securities that may be registered on Form S-3 pursuant to a request made under Section 2.3 hereof;

(vii) If the Initiating Holders do not request that such offering be firmly underwritten by underwriters selected by the Initiating Holders holding in the aggregate a majority the Registrable Securities held by such Initiating Holders (subject to the consent of the Company, which consent shall not be unreasonably withheld, delayed or conditioned); or

(viii) If the Company and the Initiating Holders are unable to obtain the commitment of the underwriter described in clause (b)(vii) above to firmly underwrite the offer.

(c) Deferral. If (i) in the good faith judgment of the Board, the filing of a registration statement covering the Registrable Securities would be materially 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 (or other comparable senior executive officer) of the Company stating that in the good faith judgment of the Board, it would be materially 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 (in addition to the limitations set forth in Section 2.1(b)(v) above) the Company shall have the right to defer such filing for a period of not more than one hundred (100) days after receipt of the request of the Initiating Holders, and, provided further, that the Company shall not defer its obligation in this manner more than two (2) times in any twelve-month period.

(d) Other Shares. The registration statement filed pursuant to the request of the Initiating Holders may, subject to the provisions of Section 2.1(e), include Other Shares, and may include securities of the Company being sold for the account of the Company.

(e) Underwriting. If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as part of their request made pursuant to this Section 2.1 and the Company shall include such information in the written notice given pursuant to Section 2.1(a)(i). In such event, the right of any Holder to include all or any portion of its Registrable Securities in a registration pursuant to this Section 2.1 shall be conditioned upon such Holder’s participation in a underwriting. In such case, if the Company shall request inclusion in any registration pursuant to Section 2.1 of securities being sold for its own account, or if other persons shall request inclusion in any registration pursuant to Section 2.1, the Initiating Holders shall, on behalf of all Holders, offer to include such securities in the underwriting and such offer shall be conditioned upon the

participation of the Company or such other persons in such underwriting and the inclusion of the Company’s and such person’s other securities of the Company and their acceptance of the further applicable provisions of this Section 2 (including Section 2.10). 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 the Initiating Holders holding in the aggregate a majority of the Registrable Securities held by the Initiating Holders, which underwriters are reasonably acceptable to the Company.

Notwithstanding any other provision of this Section 2.1, if the underwriters advise the Initiating Holders in writing that marketing factors require a limitation on the number of shares to be underwritten, the number of Registrable Securities and Other Shares that may be so included shall be allocated as follows: (i) first, among all Holders requesting to include Registrable Securities in such registration statement based on the pro rata percentage of Registrable Securities held by such Holders, assuming conversion (provided that if, by operation of this clause (i), the number of Registrable Securities to be so included is reduced to less than 50% of the aggregate number of Registrable Securities so requested by all Holders to be included, then the holders of a majority of the Registrable Securities may withdraw the request for such registration and, in such a case, (A) such registration shall not be counted as a registration “initiated” by the Company for purposes of Section 2.1(b)(iv) or “effected” by the Company for purposes of Section 2.3(b)(iii) and (B) the Company shall bear the Registration Expenses of such registration notwithstanding any provision of Section 2.4 to the contrary); and (ii) second, among all Other Selling Stockholders requesting to include Other Shares in such registration statement based on the pro rata percentage of Other Shares held by such Other Selling Stockholders, assuming conversion; and (iii) third, to the Company, which the Company may allocate, at its discretion, for its own account, or for the account of other stockholders or employees of the Company. 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 Initiating Holders. The securities so excluded shall also be withdrawn from registration. Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall also be withdrawn from such 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 pursuant to this Section 2.1(e), then the Company shall then offer to all Holders and Other Selling Stockholders who have retained rights to include securities in the registration the right to include additional Registrable Securities or Other Shares in the registration in an aggregate amount equal to the number of shares so withdrawn, with such shares to be allocated among such Holders and Other Selling Stockholders requesting additional inclusion, as set forth above.

2.2 Company Registration.

(a) Registration. 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, other than a registration pursuant to Section 2.1 or 2.3, a registration relating solely to employee benefit plans, a registration relating to the offer and sale of debt securities only, or a registration relating to a corporate reorganization or other Rule 145 transaction, the Company will:

(i) promptly give written notice of the proposed registration to all Holders; and

(ii) use its commercially reasonable efforts to include in such registration (and any related qualification under blue sky laws or other compliance), except as set forth in Section 2.2(b) below, and in any underwriting involved therein, all of such Registrable Securities as are specified in a written request or requests made by any Holder or Holders received by the Company within ten (10) days after such written notice from the Company is mailed or delivered. 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 involving an underwriting, the Company shall so advise the Holders as a part of the written notice given pursuant to Section 2.2(a)(i). In such event, the right of any Holder to registration pursuant to this Section 2.2 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company, the Other Selling Stockholders and 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 2.2, if the underwriters advise the Company in writing that marketing factors require a limitation on the number of shares to be underwritten, the underwriters may (subject to the limitations set forth below) limit the number of Registrable Securities to be included in, the registration and underwriting, 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, as follows: (i) first, to the Company for securities being sold for its own account, (ii) second, to the Holders requesting to include Registrable Securities in such registration statement based on the pro rata percentage of Registrable Securities held by such Holders, assuming conversion; and (iii) third, to the Other Selling Stockholders requesting to include Other Shares in such registration statement based on the pro rata percentage of Other Shares held by such Other Selling Stockholders, assuming conversion. Notwithstanding the foregoing, no such reduction shall reduce the value of the Registrable Securities of the Holders included in such registration below twenty-five percent (25%) of the total value of securities included in such registration, unless such offering is an Initial Public Offering and such registration does not include shares of any

Other Selling Stockholders (excluding shares registered for the account of the Company), in which event any or all of the Registrable Securities of the Holders may be excluded.

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 also be excluded therefrom by written notice from the Company or the underwriter. The Registrable Securities or other securities so excluded shall also be withdrawn from such registration. Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall be withdrawn from such registration.

(c) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 2.2 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration.

2.3 Registration on Form S-3.

(a) Request for Form S-3 Registration. After its Initial Public Offering, the Company shall use its commercially reasonable 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 2 and subject to the conditions set forth in this Section 2.3, if the Company shall receive from a Holder or Holders of Registrable Securities a written request that the Company effect any registration on Form S-3 or any similar short form registration statement with respect to all or part of the Registrable Securities (such request shall state the number of shares of Registrable Securities to be disposed of and the intended methods of disposition of such shares by such Holder or Holders), the Company will take all such action with respect to such Registrable Securities as required by Sections 2.1(a)(i) and 2.1(a)(ii).

(b) Limitations on Form S-3 Registration. The Company shall not be obligated to effect, or take any action to effect, any such registration pursuant to this Section 2.3:

(i) In the circumstances described in any of Sections 2.1(b)(i), 2.1(b)(iii) or 2.1(b)(v);

(ii) If the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) on Form S-3 at an aggregate price to the public of less than $2,000,000 (net of underwriting discounts and commissions); or

(iii) If, in a given twelve-month period, the Company has effected two (2) such registrations in such period.

(d) Underwriting. If the Holders of Registrable Securities requesting registration under this Section 2.3 intend to distribute the Registrable Securities covered by their

request by means of an underwriting, the provisions of Section 2.1(e) shall apply to such registration. Notwithstanding anything contained herein to the contrary, registrations effected pursuant to this Section 2.3 shall not be counted as requests for registration or registrations effected pursuant to Section 2.1.

2.4 Expenses of Registration. All Registration Expenses incurred in connection with registrations pursuant to Sections 2.1, 2.2 and 2.3 hereof shall be borne by the Company; provided, however, that, subject to Section 2.1(e), the Company shall not be required to pay for any Registration Expenses of any registration proceeding begun pursuant to Sections 2.1 and 2.3 if the registration request is subsequently withdrawn at the request of the Preferred Majority or because a sufficient number of Holders shall have withdrawn so that the minimum offering conditions set forth in Section 2.1 and 2.3 are no longer satisfied (in which case all participating Holders shall bear such expenses pro rata among each other based on the number of Registrable Securities requested to be so registered), unless the Preferred Majority agree to forfeit their right to a demand registration pursuant to Section 2.1; provided, however, in the event that a withdrawal by the Holders is based upon material adverse information relating to the Company that is different from the information known or available (upon request from the Company or otherwise) to the Holders requesting registration at the time of their request for registration under Sections 2.1 or 2.3, such registration shall not be treated as a counted registration for purposes of Sections 2.1 or 2.3 hereof, and the Company shall bear the Registration Expenses for such registration. All Selling Expenses relating to securities registered on behalf of the Holders shall be borne by the holders of securities included in such registration pro rata among each other on the basis of the number of Registrable Securities so registered.

2.5 Registration Procedures.

At its expense, the Company will use its commercially reasonable efforts to:

(f) Notify each seller 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 or incomplete in light of the circumstances then existing, and following such notification promptly prepare and furnish to such seller a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such shares, such prospectus shall not include an 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 or incomplete in light of the circumstances then existing;

(b) To the extent permitted by law, 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, severally and not jointly, indemnify and hold harmless 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 each of their officers, directors and partners, and each person controlling each other such Holder, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on (in each case only to the extent that such claims, losses, damages and liabilities arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of such selling Holder expressly for use in connection with such registration): (i) any untrue statement (or alleged untrue statement) of a material fact contained or incorporated by reference 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 (ii) 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, 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 the aggregate amounts payable by any Holder by way of indemnity or contribution under this Section 2.6(b) and Section 2.6(d) exceed the net proceeds from the offering received by such Holder, except in the case of fraud or willful misconduct by such Holder.

(c) Each party entitled to indemnification under this Section 2.6 (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 2.6, 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) If the indemnification provided for in this Section 2.6 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage, or expense referred to herein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission. In no event shall a Holder’s liability pursuant to this Section 2.6(d), when combined with the amounts paid or payable by such Holder pursuant to Section 2.6(b), exceed the net proceeds from the offering received by such Holder, except in the case of fraud or willful misconduct by such Holder. 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.

(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into by the Investors in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control; provided that the failure of the underwriting agreement to provide for or address a matter provided for or addressed in the foregoing provisions shall not be a conflict with the foregoing provisions and, in such event, the foregoing provisions shall control.

2.7 Information by Holder. Each Holder of Registrable Securities shall furnish to the Company such information regarding such Holder and the distribution proposed by such Holder as the Company may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification, or compliance referred to in this Section 2.

2.8 Restrictions on Transfer.

(a) The holder of each certificate representing Registrable Securities by acceptance thereof agrees to comply in all respects with the provisions of this Section 2.8. Each Holder agrees not to make any sale, assignment, transfer, pledge or other disposition of all or any portion of the Restricted Securities, or any beneficial interest therein, unless and until:

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

(ii) (x) if such transfer is prior to the Company’s Initial Public Offering, the Holder shall have given prior written notice to the Company of the Holder’s intention to make such disposition and shall have furnished the Company with a detailed description of the manner and circumstances of the proposed disposition, (y) if such transfer is prior to the Company’s Initial Public Offering, the transferee thereof shall have agreed in writing for the benefit of the Company to take and hold such Restricted Securities subject to, and to be bound by, the terms and conditions set forth in this Agreement, including, without limitation, this Section 2.8 and Section 2.10, and (z) if reasonably requested by the Company, the Holder shall have furnished the Company, at its expense, with (1) an opinion of counsel reasonably satisfactory to the Company to the effect that such disposition will not require registration of such Restricted Securities under the Securities Act or (2) a “no action” letter from the Commission to the effect that the transfer of such securities without registration will not result in a recommendation by the staff of the Commission that action be taken with respect thereto, whereupon the holder of such Restricted Securities shall be entitled to transfer such Restricted Securities in accordance with the terms of the notice delivered by the Holder to the Company.

(b) Notwithstanding the provisions of Section 2.8(a), no such registration statement, opinion of counsel or “no action” letter shall be required for (i) a transfer not involving a change in beneficial ownership, (ii) a transfer under Rule 144, except in unusual circumstances, or (iii) transactions involving the transfer of Restricted Securities by any Holder to (x) a parent, subsidiary or other Affiliate of the Holder; (y) any of the Holder’s partners, members or other equity owners, or retired partners, retired members or other equity owners, or to the estate of any of the Holder’s partners, members or other equity owners or retired partners, retired members or other equity owners; or (z) to any venture capital fund, private equity fund or other investment fund that, in each case, is controlled by or under common control with one or more general partners or managing members of, or shares the same management company or registered investment adviser with, the Holder; provided, in each case, that the Holder shall give written notice to the Company of the Holder’s intention to effect such disposition and shall have furnished the Company with a detailed description of the manner and circumstances of the proposed disposition and, if such transfer is prior to the Company’s Initial Public Offering, the transferee thereof shall have agreed in writing for the benefit of the Company to take and hold

such Restricted Securities subject to, and to be bound by, the terms and conditions set forth in this Agreement, including, without limitation, this Section 2.8 and Section 2.10.

(c) 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 OFFER AND SALE OF THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED EXCEPT AS PERMITTED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS PURSUANT TO REGISTRATION OR AN EXEMPTION THEREFROM. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER THAT SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

THE SHARES EVIDENCED HEREBY ARE SUBJECT TO A VOTING AGREEMENT (A COPY OF WHICH MAY BE OBTAINED UPON WRITTEN REQUEST FROM THE ISSUER), AND BY ACCEPTING ANY INTEREST IN SUCH SHARES THE PERSON ACCEPTING SUCH INTEREST SHALL BE DEEMED TO AGREE TO AND SHALL BECOME BOUND BY ALL THE PROVISIONS OF SAID VOTING AGREEMENT.

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE, INCLUDING A LOCK-UP PERIOD IN THE EVENT OF A PUBLIC OFFERING, AS SET FORTH IN AN INVESTORS’ RIGHTS AGREEMENT AMONG THE COMPANY AND THE ORIGINAL HOLDERS OF THESE SHARES, COPIES OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE COMPANY.

The Holders consent to the Company making a notation on its records and giving instructions to any transfer agent of the Restricted Securities in order to implement the restrictions on transfer established in this Section 2.8.

(d) The first legend referring to federal and state securities laws identified in Section 2.8(b) hereof stamped on a certificate evidencing the Restricted Securities and the stock transfer instructions and record notations with respect to such Restricted Securities shall be removed and the Company shall issue a certificate without such legend to the holder of such

Restricted Securities if (i) such securities are registered under the Securities Act or, if following the Initial Public Offering, such securities are sold pursuant to Rule 144, or (ii) such holder provides the Company with an opinion of counsel reasonably acceptable to the Company to the effect that a sale or transfer of the securities may be made without registration or qualification.

(e) Notwithstanding anything to the contrary in this Agreement, (i) any or all of an Investor’s rights hereunder may be exercised by, and any or all of an Investor’s obligations hereunder may be discharged by, one or more Affiliates of such Investor designated by such Investor and (ii) more specifically, (x) an Investor may cause any shares of capital stock of the Company (or any securities directly or indirectly exercisable for, or convertible into or exchangeable for, such shares) required or permitted to be purchased or otherwise acquired hereunder by such Investor to be so purchased or acquired, in lieu of such Investor, by an Affiliate of such Investor (and such Affiliate shall then become an “Investor” hereunder), and (y) any Investor holding securities directly or indirectly exercisable for, or convertible into or exchangeable for, shares of capital stock of the Company shall have the right to have any such shares (or other securities) issuable upon the conversion, exercise or exchange of the securities held by such Investor issued in the name of one or more Affiliates of such Investor designated by such Investor (and each such Affiliate shall then become an “Investor” hereunder).

2.9 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, the Company agrees to use its commercially reasonable efforts to:

(a) Make and keep adequate current public information with respect to the Company available in accordance with Rule 144 under the Securities Act, at all times following 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 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.

2.10 Market Stand-Off Agreement. Each Holder hereby agrees that it will not, without the prior written consent of the managing underwriter, during the period commencing on the date of the final prospectus relating to the Initial Public Offering and ending on the date specified by the Company and the managing underwriter (such period not to exceed one hundred eighty (180) days, or such other period as may be reasonably requested by the underwriters to

accommodate regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto) (i) lend, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock held immediately before the effective date of the registration statement for the Initial Public Offering, or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise. The foregoing provisions of this Section 2.10 (A) shall apply only to the Initial Public Offering, (B) shall not apply to shares of Common Stock acquired in the Initial Public Offering or in the open market following the Initial Public Offering, (C) shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement, and (D) shall only be applicable to the Holders if all officers, directors and greater than one percent (1%) stockholders of the Company enter into similar agreements. The underwriters in connection with the Initial Public Offering are intended third-party beneficiaries of this Section 2.10 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. Each Holder further agrees to execute such agreements as may be reasonably requested by the underwriters in the Initial Public Offering that are consistent with this Section 2.10 or that are necessary to give further effect thereto. If any of the obligations described in this Section 2.10 are waived or terminated with respect to any of the securities of any such Holder, officer, director or greater than one-percent stockholder (in any such case, the “Released Securities”), the foregoing provisions shall be waived or terminated, as applicable, to the same extent and with respect to the same percentage of securities of each Holder as the percentage of Released Securities represent with respect to the securities held by the applicable Holder, officer, director or greater than one-percent stockholder, subject to customary and mutually agreeable exceptions.

In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to the Registrable Securities of each Holder (and the shares or securities of every other person subject to the foregoing restriction) until the end of such period.

2.11 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 2.

2.12 Transfer or Assignment of Registration Rights. The rights to cause the Company to register securities granted to a Holder by the Company under this Section 2 may be transferred or assigned by a Holder only to a transferee or assignee of not less than twenty percent (20%) of the Registrable Securities (as presently constituted and subject to subsequent adjustments for stock splits, stock dividends, reverse stock splits, and the like) then held by such Holder; provided that (i) such transfer or assignment of Registrable Securities is effected in accordance with the terms of Section 2.8 hereof and applicable securities laws, (ii) the Company is given written notice prior to said transfer or assignment, stating the name and address of the transferee or assignee and identifying the securities with respect to which such registration rights

are intended to be transferred or assigned and (iii) the transferee or assignee of such rights assumes in writing the obligations of such Holder under this Agreement, including without limitation the obligations set forth in Section 2.10.

2.13 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of the Preferred Majority, 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 senior to or on parity with the registration rights granted to the Holders hereunder.

2.14 Termination of Registration Rights. The right of any Holder to request registration or inclusion in any registration pursuant to Sections 2.1, 2.2 or 2.3 shall terminate on the earlier of (i) such date, on or after the closing of the Company’s first registered public offering of Common Stock, on which all shares of Registrable Securities held or entitled to be held upon conversion by such Holder may immediately be sold under Rule 144 during any ninety (90) day period (and without the requirement for the Company to be in compliance with the current public information required under Section (c)(1) of Rule 144) and (ii) four (4) years after the closing of a Qualified Public Offering.

3. Information Covenants of the Company.

The Company hereby covenants and agrees, as follows:

3.1 Basic Financial Information and Observation Rights.

(a) Basic Financial Information. As long as least 20% of the aggregate shares of Preferred Stock issued pursuant to the Series A Purchase Agreement and Series B Purchase Agreement remain outstanding, the Company will furnish to each Holder who continues to hold the equivalent of at least five percent (5%) of the outstanding shares of the applicable series of Preferred Stock (each such Holder, a “Major Holder”):

(i) as soon as practicable after the end of each fiscal year of the Company, and in any event within 120 days after the end of each fiscal year of the Company a consolidated balance sheet of the Company and its subsidiaries, if any, as at the end of such fiscal year, and consolidated statements of income and cash flows of the Company and its subsidiaries, if any, for such year, prepared in accordance with U.S. generally accepted accounting principles consistently applied, and audited and certified by independent public accountants of recognized national standing selected by the Company;

(ii) as soon as practicable after the end of the first, second and third quarterly accounting periods in each fiscal year of the Company, and in any event within 45 days after the end of the first, second, and third quarterly accounting periods in each fiscal year of the Company, an unaudited consolidated balance sheet of the Company and its subsidiaries, if any, as of the end of each such quarterly period, and unaudited consolidated statements of income and cash flows of the Company and its subsidiaries, if any, for such period, prepared in accordance with U.S. generally accepted accounting principles consistently applied, subject to changes resulting from normal year-end audit adjustments and such financial statements may not contain accompanying notes;

(iii) as soon as practicable after the each month, and in any event within 30 days after the end of each such month, an unaudited consolidated balance sheet of the Company and its subsidiaries, if any, as of the end of each such monthly period, and unaudited consolidated statements of income and cash flows of the Company and its subsidiaries, if any, for such period, prepared in accordance with U.S. generally accepted accounting principles consistently applied, subject to changes resulting from normal year-end audit adjustments and such financial statements may not contain accompanying notes;

(iv) at least 30 days prior to the beginning of each of the Company’s fiscal years an annual operating plan for such fiscal year (and as soon as available, any subsequent material revisions thereto); and

(v) as soon as practicable after the end of each fiscal year, and in any event within 30 days thereafter, a report setting forth in detail all equity and debt holders of the Company as of the end of such year.

(b) Inspection Rights. So long as at least twenty percent (20%) of the aggregate shares of Preferred Stock issued pursuant to the Series A Purchase Agreement and Series B Purchase Agreement remain outstanding (as presently constituted and subject to subsequent adjustments for stock splits, stock dividends, reverse stock splits, and the like) are issued and outstanding, the Company shall permit each Major Holder, at such Major Holder’s expense, to visit and inspect any of the properties of the Company or any of its subsidiaries during normal business hours or at such other reasonable times as may be requested, and to discuss the affairs, finances and accounts of the Company or any of its subsidiaries with its officers, and to review such information as is reasonably requested all at such reasonable times and as often as may be reasonably requested; provided, however, that the Company shall not be obligated under this Section 3.1(b) with respect to a competitor of the Company (as determined by the Board in good faith, but subject to Section 3.3) or with respect to information which the Board determines in good faith is highly confidential or attorney-client privileged and should not, therefore, be disclosed. Such Major Holder may exercise its rights under this Section 3.1(b) only for purposes reasonably related to their interests as stockholders of the Company, or under this Agreement and related agreements as stockholders. The rights granted pursuant to this Section 3.1(b) may not be assigned or otherwise conveyed to a Holder or by any subsequent transferee of any such rights without the prior written consent of the Company; provided, however, that a Holder shall be permitted to transfer rights granted pursuant to this Section 3.1(b) to Affiliates, partners, members, limited partners, retired partners, stockholders or affiliated venture capital or similar investment funds of such Major Holder, so long as such Major Holder, together with its transferees permitted under this Section 3.1(b), continue to hold a sufficient number of Shares to constitute a Major Holder hereunder (including shares held by such Major Holder’s Affiliates as provided under Section 6.11).

3.2 Confidentiality. Each Holder agrees that such Holder will keep confidential and will not use for any purpose (other than to monitor it investment) or disclose or divulge any confidential information obtained from the Company pursuant to the terms of this Agreement (including notice of the Company’s intention to file a registration statement and the contents of any financial statements received), unless such confidential information (a) is known or becomes known to the public in general (other than as a result of a breach of this Section 3.2 by such

Holder or as a result of a breach by a third party of any obligation of confidentiality such third party may have to the Company of which such Holder is aware), (b) is or has been independently developed or conceived by the Investor without use of or reference to the Company’s confidential information, or (c) is or has been made known or disclosed to the Holder by a third party without a breach of any obligation of confidentiality such third party may have to the Company; provided, however, that a Holder may disclose confidential information (i) to its attorneys, accountants, consultants, and other professionals to the extent necessary to obtain their services in connection with monitoring its investment in the Company, provided such persons agree to hold such information confidentially as provided herein; (ii) to any prospective purchaser of any Registrable Securities from such Holder, if such prospective purchaser agrees to be bound by the provisions of this Section 3.2; (iii) to any existing or prospective Affiliate, partner, member, stockholder, or wholly owned subsidiary of such Holder in the ordinary course of business, provided that such Holder informs such person or entity that such information is confidential and directs such person or entity to maintain confidential treatment of such information; or (iv) as may otherwise be required by law, court order or an applicable governmental or regulatory body, provided that the Holder promptly notifies the Company of such disclosure and takes reasonable steps to minimize the extent of any such required disclosure.

3.3 Observer Rights. So long as at least twenty percent (20%) of the aggregate shares of Preferred Stock issued pursuant to the Series B Purchase Agreement remain outstanding, the Company shall invite a representative designated by the holders of a majority of the outstanding Series B Preferred Stock to attend all meetings of its Board in a nonvoting observer capacity and, in this respect, shall give such representative copies of all notices, minutes, consents and other materials that it provides to its directors; provided, however, that such representative shall agree to hold in confidence and trust and to act in a fiduciary manner with respect to all information so provided; and, provided further, that the Company reserves the right to withhold any information and to exclude such representative from any meeting or portion thereof if access to such information or attendance at such meeting could adversely affect the attorney-client privilege between the Company and its counsel or would result in disclosure of trade secrets to such representative or if such Investor or its representative is or is affiliated with a competitor of the Company (provided, that an Investor that is a venture capital or other investment fund shall not be deemed to be affiliated with a competitor solely as a result of its investment in other companies).

3.4 Right to Conduct Activities. The Company hereby acknowledges that certain of the Investors and their Affiliates (each, a “Fund”) are investment funds, and as such invest in numerous portfolio companies, some of which may be deemed competitive with the Company’s business. Neither any Fund nor its partners, Affiliates, advisors or affiliated investment funds shall be deemed a competitor of the Company for purposes of Section 3.1(b) as a result of, or liable to the Company for any claim arising out of, or based upon, (i) the investment by such Fund or any affiliated investment fund in any entity competitive to the Company or (ii) actions taken by any partner, officer, advisor or other representative of such Fund in his, her or its capacity as such to assist any such competitive company; provided, however, that nothing herein shall relieve any Fund or any other party from liability associated with misuse of the Company’s confidential information as set forth in Section 3.2 above.

3.5 Termination of Covenants. The covenants set forth in Section 3.1 shall not apply to and shall terminate and be of no further force and effect after the earlier of (a) the Initial Public Offering or (b) the occurrence of a Liquidation Event.

4. Right of First Refusal.

4.1 Holders Rights. Subject to the provisions of Section 4.2 through 4.5 below, the Company hereby grants to each Major Holder who is an “accredited investor” within the meaning of applicable securities laws and regulations (a “ROFR Holder”), the right of first refusal to purchase its Pro Rata Amount (as defined below) of New Securities which the Company may, from time to time, propose to sell and issue after the date of this Agreement. A ROFR Holder’s “Pro Rata Amount”, for purposes of this right of first refusal, is equal to the ratio of (a) the number of shares of Common Stock (except for Common Stock originally issued as Common Stock which were not issued upon conversion of Preferred Stock) and Preferred Stock and all other shares of any other convertible securities, rights, options or warrants held by such ROFR Holder (“ROFR Shares”), on an as exercised and as converted to Common Stock basis, to (b) the total of all outstanding shares of Common Stock, all outstanding shares of Preferred Stock and all other shares of other convertible securities, rights, options or warrants then outstanding, on an as exercised and as converted to Common Stock basis, and all shares of Common Stock held in reserve in any of the Company’s equity incentive plans that are not then yet allocated for outstanding and unexercised stock options.

4.2 New Securities. As used herein, “New Securities” shall mean any capital stock (including Common Stock and/or Preferred Stock) of the Company whether now authorized or not, and rights, convertible securities, options or warrants to purchase such capital stock, and securities of any type whatsoever that are, or may become, exercisable or convertible into capital stock; provided that the term “New Securities” does not include (i) any securities that are not deemed to be “Additional Stock” pursuant to Article IV, Section B.4(d)(ii) of the Restated Certificate or (ii) any shares of Series B Preferred Stock issued pursuant to the Series B Purchase Agreement (although nothing set forth herein shall alter the rights and obligations of the Investors to purchase shares of Series B Preferred Stock pursuant to the Series B Purchase Agreement).

4.3 Notice. In the event the Company proposes to undertake an issuance of New Securities, it shall give each ROFR 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 ROFR Holder shall have 15 days after any such notice is mailed or delivered to agree to purchase such ROFR Holder’s Pro Rata Amount (or such lesser amount as desired) 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, if any.

4.4 Election Period and Excess Securities. In the event the foregoing right of first refusal is not exercised in full by all of the ROFR Holders within the 15 day period described in Section 4.3 above (the “Election Period”), the Company shall promptly notify in writing the ROFR Holders who have elected to exercise their right of first refusal with respect to their full Pro Rata Amount and shall offer such ROFR Holders the right to acquire such unsubscribed New

Securities. Each ROFR Holder shall have 10 days after receipt of such notice to notify the Company of its election to purchase all or a portion thereof of its pro rata portion of the unsubscribed New Securities, indicate whether it intends to purchase unsubscribed New Securities in excess of its pro rata share (“Excess Securities”) and, if so, the number of such unsubscribed New Securities it wishes to purchase. The Excess Securities, if any, shall be allocated to participating ROFR Holders in a manner most consistent with the pro rata shares of such participating ROFR Holders as determined in good faith by the Board. If the ROFR Holders fail to exercise in full the rights of first refusal, the Company shall have 45 days thereafter to sell or enter into an agreement (pursuant to which the sale of New Securities covered thereby shall be closed, if at all, within 20 days from the date of said agreement) to sell that portion of the New Securities with respect to which the ROFR Holders’ right of first refusal option set forth in this Section 4 was not exercised, at a price and upon terms no more favorable to the purchasers thereof than specified in the Company’s notice to ROFR Holders delivered pursuant to Section 4.3. In the event the Company enters into an agreement to sell such New Securities within such 45 day period following the Election Period, or sells such New Securities within such 20 day period following the date of said agreement, the Company shall not thereafter issue or sell any New Securities, without first again offering such securities to the ROFR Holders in the manner provided in this Section 4.

4.5 Waiver, Expiration, Transfer. The rights of first refusal granted under this Section 4, including notice with respect thereto, may be waived as to all ROFR Holders with the written consent of the Preferred Majority. The rights of first refusal granted under this Section 4.1 shall expire immediately prior to the earlier of (i) the Initial Public Offering and (ii) the closing of a Liquidation Event. The rights of first refusal of a ROFR Holder under this Section 4 may be transferred subject to the same restrictions as any transfer of registration rights pursuant to Section 2.12. Notwithstanding anything else set forth above, a Holder shall be permitted to transfer rights granted pursuant to this Section 4 in any amount to its Affiliates.

6.3 Counterparts. This Agreement may be executed in any number of counterparts and signatures may be delivered by facsimile, each of which may be executed by less than all parties, each of which shall be enforceable against the parties actually executing such counterparts, and all of which together shall constitute one instrument.

6.4 Titles and Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement.

6.5 Notices. All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed facsimile if sent during normal business hours of the recipient, if not, then on the next business day, (c) five (5) U.S. business days after having been sent to a U.S. address by registered or certified mail, return receipt requested, postage prepaid, (d) two (2) business days after deposit with a nationally recognized overnight courier, freight prepaid, specifying next business day delivery in the United States, with written verification of receipt or (e) three (3) business days after deposit with an internationally recognized overnight courier or expedited delivery services company, specifying next available business day delivery outside of the United

All notices shall also be accompanied by e-mail delivery to those parties whose e-mail addresses appear on Exhibit A, which e-mail delivery shall not constitute notice for purposes of this Section 6.5.

6.6 Amendments and Waivers. Except as expressly provided herein, any term of this Agreement may be amended, terminated or waived only with the written consent of (a) the Company and (b) the Preferred Majority; and provided, further, that no amendment, termination or waiver of any term under this Agreement shall adversely affect any Investor or group of Investors in an adverse manner that is disproportionate to its holdings of stock relative to the other Investors of the same class or series unless such amendment, termination or waiver is agreed to in writing by a majority in interest of the disproportionately affected Investor(s); and provided, further, no amendment of or waiver to Section 2.6(b) or Section 2.6(d) shall be made that has not been approved with the written consent of each Investor to the extent that such Investor’s respective rights under such Section 2.6(b) or Section 2.6(d) are impaired; and provided, further, no amendment of or waiver to this Section 6.6 shall be made, other than in connection with the issuance of Capital Stock (as defined below), that has not been approved with the written consent of each Major Holder to the extent that such Major Holder’s respective rights under this Section 6.6 are impaired and the rights of other Investors of the same class or series are not so adversely affected. For the avoidance of doubt, the addition to this Agreement of any new holder of shares of capital stock of the Company (“Capital Stock”) pursuant to the Company’s issuance of such other Capital Stock regardless of whether such Capital Stock has rights, preferences or privileges that are junior, pari passu or senior to the Capital Stock then held by then current Investors as long as such other or additional shares of Capital Stock have been authorized and issued in accordance with the Company’s then current Restated Certificate and applicable law, and as long as the addition of such new holder of Capital Stock of the Company (or inclusion of such new shares of Capital Stock) has been approved as may be required pursuant to Section 2.13 above, shall not, in and of itself, be deemed to constitute an amendment or waiver that adversely affects one Investor in a manner that is disproportionate to any other Investor. Any amendment or waiver effected in accordance with this Section 6.6 shall be binding upon the Holders and each transferee of the Shares (or the Common Stock issuable upon conversion thereof), each future holder of all such securities, and the Company. Each Holder acknowledges that by the operation of this Section and subject to the restrictions set forth above, the Preferred Majority will have the right and power to diminish or eliminate all rights of such Holder under this Agreement. The Company shall give prompt notice of any amendment waiver hereunder to any party hereto that did not consent in writing to such amendment or waiver.

6.7 Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be held to be prohibited by or invalid under applicable law, such

provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

6.8 Delays or Omissions. No delay or omission to exercise any right, power or remedy accruing to any party upon any breach or default of any other party under this Agreement shall impair any such right, power or remedy of such party, nor shall it be construed to be a waiver of any such breach or default or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing or as provided in this Agreement. All remedies, either under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative.

6.9 Entire Agreement. This Agreement (including the Exhibits hereto) constitutes the full and entire understanding and agreement among the parties with respect to the subject matter hereof and thereof, and supersedes all other agreements of the parties relating to the subject matter hereof and thereof, and supersedes in its entirety the Prior Agreement, which shall have no further force and effect.

6.10 Further Assurances. At any time or from time to time after the date hereof, the parties hereto agree to cooperate with each other, and at the request of any such party hereto, to execute and deliver any further instruments or documents and to take all such further action as the other party may reasonably request in order to evidence or effectuate the consummation of the transactions contemplated hereby and to otherwise carry out the intent of the parties hereunder.

6.11 Aggregation of Stock. All shares of Company equity held or acquired by a Holder and/or its Affiliates shall be aggregated together for the purpose of determining the availability of any rights and any obligations under this Agreement, and such affiliated persons may apportion such rights and obligations as among themselves in any manner they deem appropriate.

6.12 Additional Investors. Notwithstanding anything to the contrary contained herein, if the Company issues additional shares of Series B Preferred Stock after the date hereof, any purchaser of such shares of Series B Preferred Stock may become a party to this Agreement by executing and delivering an additional counterpart signature page to this Agreement and thereafter shall be deemed an “Investor” for all purposes hereunder and the addition of such purchasers shall not be deemed to be an amendment requiring the consent of any party hereto pursuant to Section 6.

6.13 WAIVER OF JURY TRIAL. EACH PARTY HERETO AND ANY OTHER PERSON CLAIMING ANY RIGHTS HEREUNDER, HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF ANY PARTY HERETO IN

THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT HEREOF. If the waiver of jury trial set forth in this section is not enforceable, then any claim or cause of action arising out of or relating to this Agreement shall be settled by judicial reference pursuant to California Code of Civil Procedure Section 638 et seq. before a referee sitting without a jury, such referee to be mutually acceptable to the parties or, if no agreement is reached, by a referee appointed by the Presiding Judge of the California Superior Court for Santa Xxxxx County. This paragraph shall not restrict a party from exercising remedies under the Uniform Commercial Code or from exercising pre-judgment remedies under applicable law.
