The term “Form S-3” means such form under the Securities Act as is in effect on the date hereof or any successor registration form under the Securities Act subsequently adopted by the SEC (as defined below) which permits inclusion or incorporation of substantial information by reference to other documents filed by the Company with the SEC.

The term “Transfer” means any sale, assignment, encumbrance, hypothecation, pledge, conveyance in trust, gift, or other transfer or disposition of any kind, including but not limited to transfers to receivers, levying creditors, trustees or receivers in bankruptcy proceedings or general assignees for the benefit of creditors, whether voluntary or by operation of law, directly or indirectly, of shares of the Series A Preferred Stock, the Series B Preferred Stock, the Series C Preferred Stock or the Series D Preferred Stock (or the Common Stock issued or issuable upon the conversion of such shares), except (i) any bona fide pledge made pursuant to a bona fide loan transaction that creates a mere security interest, (ii) if such shares are held by a partnership, limited liability company, or trust, (A) to partners, members, officers, employees, and affiliates of such partnership, limited liability company, or trust or any partner, officer or employee of such affiliates (collectively, “Affiliates”), (B) to its general or limited partners, stockholders or beneficiaries, or to an entity owned by or organized for the benefit of the general or limited partners, stockholders, officers, directors, employees, Affiliates or beneficiaries of such holder, as applicable, or (C) to an entity that controls, or is controlled by, or is under common control with such partnership or limited liability company, (iii) if such shares are held by a corporation, (A) to Affiliates, (B) to its stockholders, or to an entity owned by or organized for the benefit of the stockholders, officers, directors, employees, Affiliates or beneficiaries of such holder, as applicable, or (C) to an entity that controls, or is controlled by, or is under common control with such corporation, (iv) for a Transfer made by an Investor party to that certain Fourth Amended and Restated Right of First Refusal and Co-Sale Agreement between the Company and the parties thereto dated as of the date hereof, as amended (the “Co-Sale Agreement”), pursuant to and in accordance with the right of co-sale provided therein, or (v) in connection with a sale to the public pursuant to a registration statement filed by the Company with the SEC under the Securities Act; provided, that in each of cases (i), (ii), (iii) and (iv) above, each pledgee, transferee or distributee shall, as a condition precedent to such pledge or Transfer, execute either, in the Company’s sole discretion, a counterpart copy of this Agreement or a written acknowledgment that it takes such shares subject to the restrictions and provisions of this Agreement; and provided further, that in each of the cases of (i) and (iii), each pledgee, transferee or distributee is not a competitor of the Company as determined in good faith by the Board of Directors. For purposes of this Section 1.1(h), any subsidiary of a Holder in which such Holder owns at least ninety-five percent (95%) of the voting securities shall not be deemed to be a competitor of the Company. Notwithstanding the foregoing or anything to the contrary contained herein, Freescale Semiconductor, Inc. shall be permitted to transfer its shares of the Company’s securities to Motorola, Inc., provided that, with respect to such securities,

Motorola, Inc. shall be subject to and bound by the terms of this Agreement, the Second Amended and Restated Voting Agreement between the Company and the parties thereto dated as of the date hereof, as amended, and the Co-Sale Agreement. For the avoidance of doubt, a transfer of Freescale’s shares of the Company’s securities to Motorola shall not be deemed a Transfer for purposes of this Agreement.

1.2 Demand Registration.

(a) Request by Holders. If the Company shall receive a written request from the Holders of at least thirty percent (30%) of the Registrable Securities Then Outstanding not earlier than the earlier of (i) three (3) years after the date of the Prior Rights Agreement or (ii) six months after 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, that the Company file a registration statement under the Securities Act covering the registration of at least twenty-five percent (25%) of the Registrable Securities (or a lesser amount if the anticipated aggregate offering price, net of underwriting discounts and commissions, would exceed Seven Million Five Hundred Thousand Dollars ($7,500,000)) pursuant to this Section 1.2, then the Company shall, within ten (10) business days of the receipt of such written request, give written notice of such request (“Request Notice”) to all Holders, and effect, as soon as practicable, the registration under the Securities Act of all Registrable Securities which Holders request to be registered and included in such registration by written notice given by such Holders to the Company within twenty (20) days after receipt of the Request Notice, subject to the limitations of this Section 1.2.

(b) Underwriting. If the Holders initiating the registration request under this Section 1.2 (“Initiating Holders”) intend to distribute the Registrable Securities covered by their request by means of an underwriting, then they shall so advise the Company as a part of their request made pursuant to this Section 1.2 and the Company shall include such information in the Request Notice. In such event, the right of any Holder to include Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting (unless otherwise mutually agreed by such Holder and Initiating Holders holding a majority in interest of the Registrable Securities to be included in such registration) to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement in customary form with the managing underwriter or underwriters selected for such underwriting by the Company (and reasonably acceptable to holders of a majority of the Registrable Securities proposed to be registered). Notwithstanding any other provision of this Section 1.2, if the underwriter(s) advise(s) the Company in writing that marketing factors require a limitation of the number of securities to be underwritten, then the Company shall so advise all Holders of Registrable Securities that would otherwise be registered and underwritten pursuant hereto, and the number of Registrable Securities that may be included in the underwriting shall be reduced as required by the underwriter(s) and allocated among the Holders of Registrable Securities on a pro rata basis according to the number of Registrable Securities held by each Holder requesting registration (including the Initiating Holders); provided, however, that the number of shares of Registrable Securities to be included in such underwriting and registration shall not be reduced unless all other securities of the Company are first entirely excluded from the underwriting and registration. Any Registrable Securities excluded and withdrawn from such underwriting shall be withdrawn from the registration.

(c) Maximum Number of Demand Registrations. The Company is obligated to effect only two (2) such registrations pursuant to this Section 1.2 and shall not be obligated to effect such a registration during the six (6) month period after the effective date of the Company’s initial public offering of its securities pursuant to a registration statement filed under the Securities Act.

(d) Deferral. Notwithstanding the foregoing, if the Company shall furnish to Holders requesting the filing of a registration statement pursuant to this Section 1.2 a certificate signed by the President or Chief Executive Officer of the Company stating that, in the good faith judgment of the Board of Directors of the Company (the “Board of Directors”), it would be seriously detrimental to the Company and its stockholders for such registration statement to be filed and it is therefore essential to defer the filing of such registration statement, then the Company shall have the right to defer such filing for a period of not more than ninety (90) days after receipt of the request of the Initiating Holders; provided, however, that the Company may not utilize this right more than once in any twelve (12) month period.

(e) Expenses. All registration and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for the Company and the reasonable fees and disbursements of one (1) counsel for the selling Holder or Holders (the “Registration Expenses”) shall be borne by the Company. Each Holder participating in a registration pursuant to this Section 1.2 shall bear such Holder’s proportionate share (based on the total number of shares sold in such registration other than for the account of the Company) of all discounts, commissions or other amounts payable to underwriters or brokers in connection with such offering (the “Selling Expenses”). Notwithstanding the foregoing, the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to this Section 1.2 if the registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered; provided, further, however, that if at the time of such withdrawal, (i) the Holders have learned of a material adverse change in the condition, business or prospects of the Company not known to the Holders at the time of their request for such registration and have withdrawn their request for registration with reasonable promptness after learning of such material adverse change, (ii) the withdrawal relates to the Company exercising its right to defer the registration pursuant to Section 1.2(d), or (iii) the withdrawal is the result of the reduction by the underwriters of greater than fifty percent (50%) of the Registrable Securities sought to be registered by the Holders, then the Holders shall not be required to pay any of such expenses and shall retain their rights pursuant to this Section 1.2.

1.3 Piggyback Registrations. The Company shall notify all Holders of Registrable Securities in writing at least thirty (30) days prior to filing any registration statement under the Securities Act for purposes of effecting a public offering of securities of the Company (including, but not limited to, registration statements relating to secondary offerings of securities of the Company, but excluding registration statements relating to any registration under Section 1.2 or Section 1.4 of this Agreement or to any employee benefit plan or a corporate reorganization) and will afford each such Holder an opportunity to include in such registration statement all or any part of the Registrable Securities then held by such Holder. Each Holder

desiring to include in any such registration statement all or any part of the Registrable Securities held by such Holder shall, within twenty (20) days after receipt of the above-described notice from the Company, so notify the Company in writing, and in such notice shall inform the Company of the number of Registrable Securities such Holder wishes to include in such registration statement. If a Holder decides not to include all of its Registrable Securities in any registration statement thereafter filed by the Company, such Holder shall nevertheless continue to have the right to include any Registrable Securities in any subsequent registration statement or registration statements as may be filed by the Company with respect to offerings of its securities, all upon the terms and conditions set forth herein.

(a) Underwriting. If a registration statement under which the Company gives notice under this Section 1.3 is for an underwritten offering, then the Company shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder to include Registrable Securities in a registration pursuant to this Section 1.3 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the managing underwriter or underwriter(s) selected for such underwriting. Notwithstanding any other provision of this Agreement, if the managing underwriter(s) determine(s) in good faith that marketing factors require a limitation of the number of shares to be underwritten, then the managing underwriter(s) may exclude shares (including Registrable Securities) from the registration and the underwriting, and the number of shares that may be included in the registration and the underwriting shall be allocated, first, to the Company, and second, to each of the Holders requesting inclusion of their Registrable Securities in such registration statement on a pro rata basis based on the total number of Registrable Securities then held by each such Holder. No such reduction shall reduce the amount of securities of the selling Holders included in the registration below twenty-five percent (25%) of the total amount of securities included in such registration, unless such offering is the Initial Public Offering (as defined in Section 1.11 below) and such registration does not include shares of any other selling stockholders, in which event any or all of the Registrable Securities of the Holders may be excluded in accordance with the immediately preceding sentence. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the underwriter, delivered at least ten (10) business days prior to the effective date of the registration statement. Any Registrable Securities excluded or withdrawn from such underwriting shall be excluded and withdrawn from the registration. For any Holder which is a partnership, limited liability company or corporation, the partners, retired partners, members and stockholders of such Holder, or the estates and family members of any such partners, retired partners and members and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single “Holder,” and any pro rata reduction with respect to such “Holder” shall be based upon the aggregate number of Registrable Securities owned by all entities and individuals included in such “Holder,” as defined in this sentence.

(b) Expenses. All Registration Expenses incurred in connection with a registration pursuant to this Section 1.3 shall be borne by the Company. Each Holder participating in a registration pursuant to this Section 1.3 shall bear such Holder’s proportionate share (based on the total number of shares sold in such registration other than for the account of the Company) of all Selling Expenses incurred in connection with a registration pursuant to this Section 1.3.

1.4 Form S-3 Registration. In case the Company shall receive from any Holder or Holders of Registrable Securities a written request or requests that the Company effect a registration on Form S-3 and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holder or Holders, then the Company will:

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

(b) as soon as practicable, effect such registration and all such qualifications and compliances as may be so-requested and as would permit or facilitate the sale and distribution of all or such portion of such Holder’s or Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within twenty (20) days after receipt of such written notice from the Company; provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance pursuant to this Section 1.4:

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

(2) if the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public of less than Three Million Dollars ($3,000,000);

(3) if the Company shall furnish to the Holders a certificate signed by the President or Chief Executive Officer of the Company stating that, in the good faith judgment of the Board of Directors, it would be seriously detrimental to the Company and its stockholders for such Form S-3 Registration to be effected at such time, in which event the Company shall have the right to defer the filing of the Form S-3 registration statement no more than twice during any twelve (12) month period for a period of not more than ninety (90) days following receipt of the request of the Holder or Holders under this Section 1.4, provided that the Company shall not be entitled to exercise the deferral rights set forth in this Section 1.4(b)(3) to defer two consecutive requests by any Holder or Holders of Registrable Securities that the Company effect a registration on Form S-3 pursuant to this Section 1.4;

(4) if the Company has, within the twelve (12) month period preceding the date of such request, already effected two (2) registrations on Form S-3 for Holders pursuant to this Section 1.4;

(5) within three (3) months of the effective date of any registration referenced to in Sections 1.2 or 1.3 above, provided that the initiating Holder was permitted to sell Registrable Securities in such prior registration without a reduction in excess of ten percent (10%) of the number of such Holder’s Registrable Securities initially requested by such Holder to be registered in such registration; or

(6) in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance.

(c) Expenses. Subject to the foregoing, the Company shall file a Form S-3 registration statement covering the Registrable Securities and other securities so requested to be registered pursuant to this Section 1.4 as soon as practicable after receipt of the request(s) of the Holder(s) for such registration. Until such time as two (2) registrations pursuant to this Section 1.4 are declared effective by the SEC, all Registration Expenses shall be borne by the Company and each Holder participating in a registration pursuant to this Section 1.4 shall bear such Holder’s proportionate share (based on the total number of shares sold in such registration other than for the account of the Company) of all Selling Expenses. Notwithstanding the foregoing, the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to this Section 1.4 if the registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered; provided, however, that if at the time of such withdrawal, (i) the Holders have learned of a material adverse change in the condition, business or prospects of the Company not known to the Holders at the time of their request for such registration and have withdrawn their request for registration with reasonable promptness after learning of such material adverse change, (ii) the withdrawal relates to the Company exercising its right to defer the registration pursuant to Section 1.4(b)(3) or (iii) the withdrawal is the result of the reduction by the underwriters of greater than fifty percent (50%) of the Registrable Securities sought to be registered by the Holders, then the Holders shall not be required to pay any of such expenses and shall retain their rights pursuant to this Section 1.4. Following the second registration pursuant to this Section 1.4 which is declared effective by the SEC, the Holders who wish to participate in a Form S-3 registration shall pay all Registration Expenses and Selling Expenses incurred in connection with each subsequent registration requested pursuant to this Section 1.4. The obligation of the Holders participating in a Form S-3 registration to pay such Registration Expenses and Selling Expenses shall be several and not joint and in such proportion so that each Holder is responsible for the portion of the expenses represented by the percentage that the number of the Registrable Securities of such Holder offered by and sold under the registration statement bears to the total number of all Registrable Securities offered by and sold under such registration statement.

(d) Not A Demand Registration. Form S-3 registrations shall not be deemed to be demand registrations as described in Section 1.2 above.

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

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

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

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

(d) use its best efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions;

(e) in the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter(s) of such offering (it being understood and agreed that, as a condition to the Company’s obligations under this clause (e), each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement);

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

(g) furnish, at the request of any Holder requesting registration of Registrable Securities, on the date that such Registrable Securities are delivered to the underwriters for sale, if such securities are being sold through underwriters, or, if such securities are not being sold through underwriters, on the date that the registration statement with respect to such securities becomes effective, (i) an opinion, dated as of such date, of the counsel representing the Company for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering and reasonably satisfactory to a majority in interest of the Holders requesting registration, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities and (ii) a “comfort” letter dated as of such date, from the independent certified public accountants of the Company, in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering and reasonably satisfactory to a majority in interest of the Holders requesting registration, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities.

1.6 Furnish Information. It shall be a condition precedent to the obligations of the Company to take any action pursuant to Sections 1.2, 1.3 or 1.4 hereof that the selling Holders shall furnish to the Company such information regarding themselves, the Registrable Securities held by them and the intended method of disposition of such securities as shall be required to timely effect the registration of their Registrable Securities.

1.7 Delay of Registration. No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 1.

1.8 Indemnification. In the event any Registrable Securities are included in a registration statement under Sections 1.2, 1.3 or 1.4 hereof:

(a) By the Company. To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the partners, members, officers, directors and attorneys of each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Securities Exchange Act of 1934, as amended, (the “Exchange Act”), against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (each a “Violation”):

(i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto;

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

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

and the Company will reimburse each such Holder, partner, member, officer or director, underwriter or controlling person for any legal or other expenses reasonably incurred by them, as incurred, in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this subsection 1.8(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such Holder, partner, member, officer, director, underwriter or controlling person of such Holder.

(b) By Selling Holders. To the extent permitted by law, each selling Holder, severally and not jointly, will indemnify and hold harmless the Company, each of its directors, each of its officers who have signed the registration statement, each of its attorneys, each person, if any, who controls the Company within the meaning of the Securities Act, any underwriter and any other Holder selling securities under such registration statement or any of such other Holder’s partners, members, directors or officers or any person who controls such Holder within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages or liabilities (joint or several) to which the Company or any such director, officer, attorney, controlling person, underwriter or other such Holder, partner, member or director, officer or controlling person of such other Holder may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; and each such Holder will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, attorney, controlling person, underwriter or other Holder, partner, member, officer, director or controlling person of such other Holder in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this subsection 1.8(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; and provided further, that the total amounts payable in indemnity by a Holder under this Section 1.8(b) in respect of any Violation shall not exceed the net proceeds received by such Holder in the registered offering out of which such Violation arises.

(c) Notice. Promptly after receipt by an indemnified party under this Section 1.8 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 1.8, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential conflict of interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party to the extent of such prejudice under this Section 1.8, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 1.8.

(d) Defect Eliminated in Final Prospectus. The foregoing indemnity agreements of the Company and Holders are subject to the condition that, insofar as they relate to any Violation made in a preliminary prospectus but eliminated or remedied in the amended prospectus on file with the SEC at the time the registration statement in question becomes effective or the amended prospectus filed with the SEC pursuant to SEC Rule 424(b) (the “Final Prospectus”), such indemnity agreement shall not inure to the benefit of any person if a copy of the Final Prospectus (i) was furnished to the indemnified party, (ii) would have cured the Violation, and (iii) was not furnished to the person asserting the loss, liability, claim or damage at or prior to the time such action is required by the Securities Act.

such sale. Within ten (10) business days after receipt of such notice, each such Qualifying Investor shall notify the Company in writing whether such Qualifying Investor desires to purchase such Qualifying Investor’s pro rata share, or any part thereof, of the Equity Securities so offered. If any Qualifying Investor fails to deliver notice in writing within such ten (10) day period of its election to purchase such Qualifying Investor’s full pro rata share of an offering of Equity Securities (a “Nonpurchasing Investor”), then such Nonpurchasing Investor shall forfeit the right hereunder to purchase that part of its pro rata share of such Equity Securities that it did not so elect to purchase and the Company shall promptly give each Qualifying Investor who has timely elected to purchase its full pro rata share of such offering of Equity Securities (a “Purchasing Investor”) written notice of the failure of any Nonpurchasing Investor to purchase such Nonpurchasing Investor’s full pro rata share of such offering of Equity Securities (the “Over-Allotment Notice”).

WHEREAS, the Company and the Stockholders, among others, are parties to a Fourth Amended and Restated Right of First Refusal and Co-Sale Agreement effective as of June 30, 2007 (the “Co-Sale Agreement”), and an Amended and Restated Voting Agreement effective as of June 30, 2007 (the “Voting Agreement”), each of which automatically terminates upon the closing of a Qualified IPO;

WHEREAS, the Co-Sale Agreement may also be terminated by a written instrument executed by the Company and the Special Holders (as defined in the Co-Sale Agreement) holding a majority of all shares of Preferred Stock held by all Special Holders; and the Voting Agreement may also be terminated by the written consent of a majority in interest of the issued and outstanding Series A Preferred, a majority in interest of the issued and outstanding Series B Preferred, a majority in interest of the issued and outstanding Series C Preferred, a majority in interest of the issued and outstanding Series D Preferred and a majority in interest of the issued and outstanding Key Holder Shares (as defined in the Voting Agreement);

WHEREAS, the Stockholders hold a requisite percentage of the Company’s securities needed to terminate the Co-Sale Agreement and the Voting Agreement, as provided in the preceding recital;

WHEREAS, in order to eliminate any uncertainty or delay with respect to the conversion of the Preferred Stock and the termination of the Co-Sale Agreement and the Voting Agreement in connection with the IPO in the event it does not constitute a Qualified IPO, the Stockholders desire to provide that in the event the final “price to public” for the IPO is authorized and approved by the Board or the Pricing Committee of the Board, then effective immediately prior to the closing of the IPO, (i) each share of Preferred Stock then outstanding shall be automatically converted into Common Stock and (ii) the Co-Sale Agreement and Voting Agreement shall automatically terminate, all as more fully set forth herein;

WHEREAS, certain of the Stockholders are parties to letter agreements with the Company (the “Observer Letters”) pursuant to which, among other things, the Company granted such Stockholders the right, subject to certain limitations, to have a representative of such Stockholder attend meetings of the Company’s Board of Directors (the “Board”) in a non-voting observer capacity, certain of which agreements automatically terminate upon the closing of an IPO that meets specified gross proceeds and per share price thresholds;

WHEREAS, in order to eliminate any uncertainty or delay with respect to the termination of the Observer Letters in connection with the IPO, such as in the event it does not meet the gross proceeds and per share price thresholds set forth in certain of the Observer Letters, each Stockholder that is a party to an Observer Letter desires to provide that in the event the final “price to public” for the IPO is authorized and approved by the Board or the Pricing Committee of the Board, then effective immediately prior to the closing of the IPO, such Observer Letter shall automatically terminate, all as more fully set forth herein;

WHEREAS, the Company and certain of the Stockholders, among others, are parties to a Third Amended and Restated Investor Rights Agreement effective as of June 30, 2007 (the “Rights Agreement”), Section 4 of which provides for a right of first refusal of the Company and certain Investors (as defined in the Rights Agreement) with respect to certain transfers of capital stock of the Company by any Investor;

WHEREAS, the Rights Agreement may be amended with the written consent of the Company and Investors (and/or any of their permitted successors or assigns) holding a majority of the Registrable Securities Then Outstanding (as defined in the Rights Agreement);

WHEREAS, the Stockholders hold a requisite percentage of the Company’s securities needed to amend the Rights Agreement, as provided in the preceding recital; and

WHEREAS, the Company and the Stockholders desire to provide that in the event the final “price to public” for the IPO is authorized and approved by the Board or the Pricing Committee of the Board, then effective immediately prior to the closing of the IPO, the obligations of each Investor under Section 4 of the Rights Agreement shall automatically terminate, all as more fully set forth herein.

AGREEMENT

NOW, THEREFORE, the parties to this Agreement, for good and valuable consideration, the receipt and sufficiency of which is acknowledged and agreed, hereby agree as follows:

1. Conversion. The Stockholders that are holders of Preferred Stock hereby agree, on behalf of themselves and all other holders of Preferred Stock, that effective immediately prior to the closing of an IPO the final “price to public” for which is authorized and approved by the Board or the Pricing Committee of the Board (an “Approved IPO”), each share of Preferred Stock then outstanding shall automatically be converted into Common Stock at the then effective Conversion Rate (as defined in the Charter).

2. Termination of Co-Sale Agreement, Voting Agreement and Observer Letters. The Company and the Stockholders hereby agree, on behalf of themselves and all other parties to the Co-Sale Agreement and the Voting Agreement, that effective immediately prior to the closing of an Approved IPO, each of the Co-Sale Agreement and the Voting Agreement shall automatically terminate in its entirety and be of no further force and effect. In addition, the Company and each Stockholder that is a party to an Observer Letter hereby agree that effective immediately prior to the closing of an Approved IPO, such Observer Letter shall automatically terminate in its entirety and be of no further force and effect.

3. Amendment of Rights Agreement. The Company and the Stockholders that are parties to the Rights Agreement hereby agree, on behalf of themselves and all other parties to the Rights Agreement, that effective immediately prior to the closing of an Approved IPO, the obligations of each Investor under Section 4 of the Rights Agreement shall automatically terminate in their entirety and be of no further force and effect.

4. Sunset. Notwithstanding anything to the contrary set forth herein, this Agreement and all obligations hereunder shall terminate at 11:59 p.m. Eastern time on December 31, 2007, if the closing of an Approved IPO has not occurred prior to such time; provided, however, that the Company may, by written notice to the Stockholders prior to November 30, 2007, extend such date for a period of up to an additional three months.

5. Miscellaneous.

The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors and assigns of the parties.

(b) Amendment; Waiver. Neither this Agreement nor any term hereof may be amended, waived, discharged or terminated other than by a written instrument signed by the party against whom enforcement of such amendment, waiver, discharge or termination is sought.

(c) Governing Law; Venue. This Agreement shall be governed by and construed under the laws of the State of California as applied to agreements among California residents, made and to be performed entirely within the State of California.

(d) Counterparts; Facsimile. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Facsimile signatures shall be as effective as original signatures.
