Section 4. Demand Registration. (a) Request for Registration. Subject to the provisions of Section 4(b), at any time any holders of a majority of the Registrable Securities may demand that the Company register all or part of its Registrable Securities under the Securities Act (a "Demand Registration"); provided, however, that the Demand Registration may not be exercised until after the consummation of all 3 Parent Conversions or the exercise or lapse of the Investor Option. Within ten (10) days after receipt of a demand, the Company will notify in writing all Investor Group Designees of the demand. Any Investor Group Designee who wants to include any of their Registrable Securities of one or more of the Investors in its Investor Group in the Demand Registration must notify the Company within ten (10) business days of receiving the notice of the Demand Registration. Except as provided in this Section 4, the Company will include in the Demand Registration all Registrable Securities for which the Company receives the timely written demands for inclusion. All demands for inclusion made pursuant to this Section 4(a) must specify the name of the Investor wishing to be included in the Demand Registration, the number of Registrable Securities to be registered and the intended method of disposing of the Registrable Securities. (b) Number and Form of Registration. The holders of the Registrable Securities shall be limited to one (1) Demand Registration, which shall be on Form S-1 (or a similar long-form registration then in effect), or, if available on Form S-3; provided, however, that the Company include in the registration statement such Company-related disclosure as is customarily included in underwritten offerings, or as reasonably requested by the holders requesting the Demand Registration. The Company will use commercially reasonable efforts to qualify for registration on Form S-3. Only Common Stock may be included in a Demand Registration. The Company shall not be obligated to effect more than one (1) underwritten offering pursuant to the Demand Registration. (c) Registration Expenses. The Company will pay all Registration Expenses for the Demand Registration; provided, however, that notwithstanding Section 8(a) hereto, the Company will not be responsible for any printing costs and expenses as well as any registration filing fees in connection with the Demand Registration; and provided, further, that the Company will not be responsible for an amount of Registration Expenses in connection with the Demand Registration equal to any Registration Expenses previously paid by the Company in connection with the S-4 Registrations pursuant to Section 3(d) hereto. (d) Selection of Underwriters. The holders requesting the Demand Registration shall select the investment banker(s) and manager(s) that will administer the offering; provided, that such investment banker(s) and manager(s) shall be of recognized national standing and the Company shall have given its prior written consent to such selection (which consent shall not be unreasonably delayed, conditioned or withheld). The Company and the holders of Registrable Securities whose shares are being registered shall enter into a customary underwriting agreement with such investment banker(s) and manager(s). (e) Priority on Demand Restrictions. If the managing underwriter gives the Company and the holders of the Registrable Securities being registered a written opinion that the number of Registrable Securities requested to be included in the Demand Registration exceeds the number of securities that can be sold, the registration will include only the number of Registrable Securities that the underwriters believe can be sold. Subject to the priority rights of the holders of securities requesting registration pursuant to the Existing Registration Rights Agreements, the number of securities registered shall be allocated, first to the holders requesting the Demand Registration, and then pro rata among the other holders of Registrable Securities, on the basis of the total number of Registrable Securities requested to be included in the registration. In addition, if the managing underwriter shall advise the Company, in writing or otherwise, that an underwriters' over-allotment option, not in excess of 15% of the total offering to be so effected, is necessary or desirable for the marketing of such offering, all Registrable Securities which are to be included in such offering pursuant to this Section 4(e) shall be allocated on the basis of the priority described in the preceding sentence. (f) Delay in Filing. Notwithstanding the foregoing, the Company may delay in filing a registration statement in connection with a Demand Registration and may withhold efforts to cause the registration statement to become effective, if the Company determines in good faith that such registration might interfere with or affect the negotiation or completion of any financing, acquisition, disposition or other transaction or other material event that is being contemplated in good faith by the Company (whether or not a final decision has been made to undertake such transaction) at the time the right to delay is exercised. The Company may exercise such right to delay or withhold efforts not more than twice in any twelve (12) month period and for not more than ninety (90) days at a time. If, after a registration statement becomes effective, the Company advises the holders of registered shares that the Company considers it appropriate for the registration statement to be amended, the holders of such shares shall suspend any further sales of their registered shares until the Company advises them that the registration statement has been amended. The 180-day time period referred to in Section 7(a)(3) during which the registration statement must be kept current after its effective date shall be extended for an additional number of business days equal to the number of business days during which the right to sell shares was suspended pursuant to the preceding sentence. (g) Effective Demand Registration. A registration shall not constitute a Demand Registration until it has become effective and remains continuously effective for the lesser of (i) the period during which all Registrable Securities registered in the Demand Registration are sold and (ii) one hundred eighty (180) days; provided, however, that a registration shall not constitute a Demand Registration if (x) after such Demand Registration has become effective, such registration or the related offer, sale or distribution of Registrable Securities thereunder is interfered with by any stop order, injunction or other order or requirement of the SEC or other governmental agency or court for any reason not attributable to the holders requesting the Demand Registration or the holders of Registrable Securities requesting to be included in such registration and such interference is not thereafter eliminated within five (5) business days, or (y) the conditions specified in the underwriting agreement, if any, entered into in connection with such Demand Registration are not satisfied or waived, other than by reason of a failure on the part of the holders requesting the Demand Registration, or (z) the number of Registrable Securities sold by the holders in such Demand Registration is less than fifty percent (50%) of the number of Registrable Securities requested to be included in such Demand Registration. (h) Limitations on Demand Registrations. The Company shall not be obligated to effect, or take any action to effect, a registration pursuant to Section 4(a) hereof if, upon receipt of a registration request pursuant to Section 4(a) hereof, the Company is advised in writing by an investment banking firm of recognized national standing selected by the Company that, in such firm's opinion, a registration at the time and on the terms requested would adversely affect any public offering of securities of the Company by the Company (other than in connection with benefit and similar plans) (a "Company Offering") with respect to which the Company has commenced preparations for a registration and filed or intends to imminently file a registration statement relating to such registration prior to the receipt of a registration request pursuant to Section 4(a) hereof, until the earlier of (i) 90 days after the completion of such Company Offering, or (ii) promptly after any abandonment of such Company Offering. Section 5. Piggyback Registrations. (a) Right to Piggyback. Whenever the Company proposes to register (including on behalf of a selling stockholder) any of its securities under the Securities Act (except for the registration of securities to be offered pursuant to an employee benefit plan on Form S-8 or Form S-3, pursuant to a registration made on Form S-4 or any successor forms then in effect) at any time other than pursuant to a Demand Registration and the registration form to be used may be used for the registration of the Registrable Securities (a "Piggyback Registration"), it will so notify in writing all Investor Group Designees no later than the earlier to occur of (i) the tenth (10th) day following the Company's receipt of notice of exercise of other demand registration rights, or (ii) thirty (30) days prior to the anticipated filing date. Subject to the provisions of Section 5(c), the Company will use its commercially reasonable efforts to include in the Piggyback Registration all Registrable Securities, on a pro rata basis based upon the total number of Registrable Securities with respect to which the Company has received written requests for inclusion within fifteen (15) days after the Investor Group Designees' receipt of the Company's notice. A registration of Registrable Securities pursuant to this Section 5 shall not be counted as a Demand Registration under Section 4. (b) Piggyback Expenses. The Company shall pay to the holders of the Registrable Securities included in a Piggyback Registration all Registration Expenses of those holders (except to the extent prohibited by applicable state securities laws). (c) Priority on Piggyback Registrations. If the managing underwriter advises the Company in writing that the total number or dollar amount of securities requested to be included in the registration exceeds the number or dollar amount of securities that can be sold, the Company will include the securities in the registration in the following order of priority, subject to the priority rights of the holders of securities requesting registration pursuant to the Existing Registration Rights Agreements: (i) first, all securities the Company or the holder for whom the Company is effecting the registration, as the case may be, proposes to sell; (ii) second, up to the full number or dollar amount of Registrable Securities requested to be included in the registration (allocated pro rata among the holders of Registrable Securities, on the basis of the number of Registrable Securities requested to be included, as the case may be); and (iii) third, any other securities (provided they are of the same class as the securities sold by the Company) requested to be included, allocated among the holders of such securities in such proportions as the Company and those holders may agree. In the event that the managing underwriter advises the Company that an underwriters' over-allotment option is necessary or advisable, the preceding priority shall apply. (d) Selection of Underwriters. If any Piggyback Registration is an underwritten offering, the Company will select the investment banker(s) and manager(s) that will administer the offering. The Company and the holders of Registrable Securities whose shares are being registered shall enter into a customary underwriting agreement with such investment banker(s) and manager(s). Section 6. Holdback Agreements. (a) Restrictions on Public Sale by Securities Holders. Each Stockholder (i) agrees not to make any public sale or distribution of equity securities of the Company (except as part of the underwritten registration effected pursuant to a Demand Registration or a Piggyback Registration), including a sale pursuant to Rule 144,during the period beginning seven (7) days prior to and ending on ninety (90) days following the effective date of any underwritten Demand Registration or any underwritten Piggyback Registration as any managing underwriter(s) of such underwriting may reasonably request, and (ii) agrees not to make any public sale or distribution of equity securities of the Company, in each case including a sale pursuant to Rule 144, during (A) the periods described in Section 5.3(b)(ii) of the Bridge Registration Rights Agreement, (B) the periods described in Section 5.3(b)(ii) of the Amended and Restated Registration Rights Agreement, and (C) the period described in Section 3(b)(ii) of the Motorola Registration Rights Agreement, provided that such agreements are in full force and effect.

The Company agrees not to make any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for its equity securities (except as part of the underwritten registration effected pursuant to a Demand Registration or a Piggyback Registration or pursuant to registrations on Forms S-8 or S-4 or any successor form or on Form S-3 with respect to any employee benefit plans of the Company), during such customary period prior to and following the effective date of any underwritten Demand Registration or any underwritten Piggyback Registration as any managing underwriter(s) of such underwriting may reasonably request. The Company also agrees to use reasonable efforts to cause each holder of at least 10% (on a fully-diluted basis) of its equity securities (other than Registrable Securities) or any securities convertible into or exchangeable or exercisable for its equity securities (other than Registrable Securities), purchased from the Company at any time on or after the date of this Agreement (other than in a registered public offering), to agree not to make any public sale or distribution of those securities, including a sale pursuant to Rule 144 (except as part of the underwritten registration, if permitted), during the seven (7) days prior to and the ninety (90) days after the effective date of the registration unless the managing underwriter(s) agrees otherwise. Section 7. Registration Procedures. (a) Obligations of the Company. Whenever the holders of Registrable Securities request or are entitled to the registration of any Registrable Securities pursuant to this Agreement, the Company shall use its commercially reasonable efforts to register and to permit the sale of the Registrable Securities in accordance with the intended method of disposition.

To the extent the Company is not required to pay Registration Expenses, each holder of securities included in any registration will pay those Registration Expenses allocable to the holder's securities so included, and any Registration Expenses not allocable will be borne by all sellers in proportion to the number of securities each registers. Furthermore, the Stockholders hereby agree amongst themselves that any Registration Expenses or other cost and expenses in connection with an S-4 Registration or the Demand Registration not required to be paid by the Company that are borne by the holders of the Registrable Securities in accordance with the previous sentence, shall be shared pro rata among the Investor Groups that are exercising or have previously exercised their right to a Parent Conversion, including, to the extent necessary, subsequent reimbursement by Investors who have previously exercised a Parent Conversion and requested an S-4 Registration to Investors then exercising a Parent Conversion and requesting an S-4 Registration. Section 9. Indemnification. (a) Indemnification by Company. In the event of any registration of Registrable Securities under the Securities Act pursuant to this Agreement, to the full extent permitted by law, the Company agrees to indemnify each holder of Registrable Securities, its officers, directors, trustees, partners, employees, advisors and agents, and each Person who controls the holder (within the meaning of the Securities Act and the Exchange Act) against all losses, claims, damages, liabilities and expenses caused by any untrue or allegedly untrue statement of material fact contained in any registration statement under which such Registrable Securities were registered under the Securities Act, any prospectus or preliminary prospectus contained therein or any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which such statements were made, except to the extent the untrue or allegedly untrue statement or omission or alleged omission resulted from information that the holder furnished in writing to the Company expressly for use therein. In connection with a firm or best efforts underwritten offering, to the extent customarily required by the managing underwriter, the Company will indemnify the underwriters, their officers and directors and each Person who controls the underwriters (within the meaning of the Securities Act and the Exchange Act), to the extent customary in such agreements. (b) Indemnification by Holders of Securities. In connection with any registration statement, each participating holder of Registrable Securities will furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any registration statement or prospectus and each holder agrees to indemnify, to the extent permitted by law, the Company, its directors, officers, trustees, partners, employees, advisors and agents, and each Person who controls the Company (within the meaning of the Securities Act and the Exchange Act) against any losses, claims, damages, liabilities and expenses resulting from any untrue or allegedly untrue statement of a material fact or any omission or alleged omission to state a material fact required to be stated in the registration statement or prospectus or any amendment thereof or supplement thereto necessary to make the statements therein not misleading in light of the circumstances under which such statements were made, but only to the extent that the untrue or allegedly untrue statement or omission or alleged omission is contained in or omitted from any information or affidavit the holder furnished in writing to the Company expressly for use therein and only in an amount not exceeding the net proceeds received by the holder with respect to securities sold pursuant to such registration statement. In connection with a firm or best efforts underwritten offering, to the extent customarily required by the managing underwriter, each participating holder of Registrable Securities will indemnify the underwriters, their officers and directors and each Person who controls the underwriters (within the meaning of the Securities Act and the Exchange Act), to the extent customary in such agreements. (c) Indemnification Proceedings. Any Person entitled to indemnification under this Agreement will (i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) unless in the indemnified party's reasonable judgment a conflict of interest may exist between the indemnified and indemnifying parties with respect to the claim, permit the indemnifying party to assume the defense of the claim with counsel reasonably satisfactory to the indemnified party. If the indemnifying party does not assume the defense, the indemnifying party will not be liable for any settlement made without its consent (but that consent may not be unreasonably withheld). No indemnifying party will consent to entry of any judgment or will enter into any settlement that does not include as an unconditional term thereof the claimant's or plaintiff's release of the indemnified party from all liability concerning the claim or litigation. An indemnifying party who is not entitled to or elects not to assume the defense of a claim will not be under an obligation to pay the fees and expenses of more than one counsel for all parties indemnified by the indemnifying party with respect to the claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between the indemnified party and any other indemnified party with respect to the claim, in which event the indemnifying party shall be obligated to pay the fees and expenses of no more than one additional counsel for the indemnified parties. (d) Contribution. If the indemnification provided for in Section 9(a) or (b) is unavailable to an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party thereunder shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the Company and the participating holders of Registrable Securities in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of the Company and the participating holders of Registrable Securities shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the participating holders of Registrable Securities and the parties' relative intent and knowledge. The parties hereto agree that it would not be just and equitable if contribution pursuant this Section 9(d) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding anything herein to the contrary, no participating holder of Registrable Securities shall be required to contribute any amount in excess of the amount by which the net proceeds of the offering (before deducting expenses, if any) received by such participating holder exceeds the amount of any damages that such participating holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. Section 10 . Rule 144. The Company covenants that it will file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder, and it will take such further action as any Investor Group Designee reasonably may request, all to the extent required from time to time, to enable such holders of Registrable Securities to sell such Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (i) Rule 144 under the Securities Act, or (ii) any similar rule or regulation hereafter adopted by the SEC. Upon the request of any holder of Registrable Securities, the Company will deliver to such holder a written statement as to whether it has complied with Rule 144's or any successor rule's requirements. The Company also covenants that in such event it will provide all such information and it will take such further action as any holder of Registrable Securities reasonably may request to enable such holder to sell Registrable Securities without registration under the Securities Act within the limitation of Rule 144 under the Securities Act or any successor rule requirements. Section 11 . Participation in Underwritten Registration. No Person may participate in any underwritten registration without (a) agreeing to sell securities on the basis provided in underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements (the holders of the Registrable Securities in a Demand Registration pursuant to Section 4(d) and the Company in a Piggyback Registration pursuant to Section 5(d)), and (b) completing and executing all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required by the underwriting arrangements. Section 12. Miscellaneous. (a) Recapitalizations, Exchanges, etc. The provisions of this Agreement shall apply to the full extent set forth herein with respect to (i) the shares of Common Stock held by the Stockholders and acquired pursuant to the transactions contemplated by the Investment Agreement (or their transferees), (ii) any and all shares of voting common stock of the Company into which the shares of such Common Stock are converted, exchanged or substituted in any recapitalization or other capital reorganization by the Company and (iii) any and all equity securities of the Company or any successor or assign of the Company (whether by merger, consolidation, sale of assets or otherwise) which may be issued in respect of, in conversion of, in exchange for or in substitution of, such shares of Common Stock and shall be appropriately adjusted for any stock dividends, splits, reverse splits, combinations, recapitalizations and the like occurring after the date hereof. The Company shall use its commercially reasonable efforts to cause any successor or assign (whether by sale, merger or otherwise) to enter into a new registration rights agreement with the holders of Registrable Securities on terms substantially the same as this Agreement as a condition of any such transaction. (b) Amendment. This Agreement may be amended or modified only by a written agreement executed by the Company and the Stockholders. (c) Attorneys' Fees. In any legal action or proceeding brought to enforce any provision of this Agreement, the prevailing party shall be entitled to recover all reasonable expenses, charges, court costs and attorneys' fees in addition to any other available remedy at law or in equity. (d) Benefit of Parties; Assignment. All of the terms and provisions of this Agreement shall be binding on and inure to the benefit of the parties and their respective successors and assigns, including, without limitation, any Person to whom the Investors may transfer any of its Registrable Securities (or any rights to acquire Registrable Securities); provided any such successor or assignee shall agree in writing to become bound by the terms of this Agreement by executing and delivering a Joinder Agreement. (e) Captions.

(g) Counterparts; Facsimile Execution. This Agreement may be executed simultaneously in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same agreement.

Except with respect to the rights granted under the Existing Registration Rights Agreements and the Warrant Registration Rights Agreement, the Company represents and warrants that it has not granted to any Person the right to request or require the Company to register any securities issued by the Company other than the rights contained herein. Except with the prior written consent of the holders of Registrable Securities, the Company will not enter into any agreement with respect to its securities that shall grant to any Person registration rights that in any way conflict with or are prior in right to the rights provided under this Agreement. The parties to this Agreement acknowledge and agree that it is their intent that this Agreement be consistent with the terms of the Existing Registration Rights Agreements and that the Company have no obligation under this Agreement which conflicts with its obligations under the Existing Registration Rights Agreements. To that end, notwithstanding anything to the contrary contained in this Agreement, to the extent that any of the provisions of this Agreement conflict with any of the provisions of the Existing Registration Rights Agreements, the Company shall not be obligated to comply with its obligations under the conflicting provisions of this Agreement until it can do so without violating the provisions of the Existing Registration Rights Agreements. (k) Notices. All notices, requests, demands, or other communications that are required or may be given pursuant to the terms of this Agreement shall be in writing and delivery shall be deemed sufficient in all respects and to have been duly given on the date of service if delivered personally to the party to whom notice is to be given, or upon receipt if mailed by first class mail, return receipt requested, postage prepaid, and properly addressed to the addresses of the parties set forth on the signature pages hereto or in the Joinder Agreement or to such other address(es) as the respective parties hereto shall from time to time designate to the other(s) in writing.

(m) Validity of Provisions. Should any part of this Agreement for any reason be declared by any court of competent jurisdiction to be invalid, that decision shall not affect the validity of the remaining portion, which shall continue in full force and effect as if this Agreement had been executed with the invalid portion eliminated, it being the intent of the parties that they would have executed the remaining portion of the Agreement without including any part or portion that may for any reason be declared invalid.
