(b) On a day (the “Shelf Notice Date”) that is at least twenty (20) Business Days prior to the date on which the Company anticipates filing a Shelf Registration Statement, the Company will deliver written notice (the “Shelf Notice”) thereof to each Stockholder that holds Registrable Securities as of the Shelf Notice Date. Each Stockholder will have the right to include its Registrable Securities and the Registrable Securities of its Affiliates in the Shelf Registration Statement by delivering to the Company a written request to so include such Registrable Securities within ten (10) calendar days after the Shelf Notice is received by any such Stockholder.

(c) Subject to Section 4.1(d), the Company shall use its reasonable best efforts to keep the Shelf Registration Statement continuously effective (including by filing any necessary post-effective amendments to such Shelf Registration Statement or one or more successor Shelf Registration Statements) until the date on which all Registrable Securities covered by the Shelf Registration Statement have been sold thereunder in accordance with the plan and method of distribution disclosed in the prospectus included in the Shelf Registration Statement, or otherwise cease to be Registrable Securities.

(d) Notwithstanding anything to the contrary contained in this Agreement, the Company shall be entitled, from time to time, by providing written notice to the Stockholders who elected to participate in the Shelf Registration Statement (which notice shall provide reasonable detail regarding the basis for the Blackout Period), to require such Stockholders and their respective Affiliates to suspend the use of the prospectus for sales of Registrable Securities under the Shelf Registration Statement during any Blackout Period. After the expiration of any Blackout Period and without any further request from a Stockholder, the Company shall immediately notify all such Stockholders and, to the extent necessary, shall as promptly as practicable prepare a post-effective amendment or supplement to the Shelf Registration Statement or the prospectus, or any document incorporated therein by reference, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Securities included therein, the prospectus will not include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

4.2 Demand Registration Rights.

(a) General. If the Company shall receive from any Major Stockholder a written request (an “Offering Request”) (i) that the Company file a registration statement with respect to any Registrable Securities of such Major Stockholder or its Affiliates (a “Registration Request”) or (ii) in the event that a Shelf Registration Statement covering such Registrable Securities is already effective, that the Company engage in an underwritten offering (an “Underwriting Request”) in respect of such Major Stockholder’s Registrable Securities, then the Company shall, within one (1) Business Day of the receipt thereof, give written notice of such request to all Major Stockholders, and the Company and the Major Stockholders shall comply with the notice and participation procedures set forth in Section 4.3. Subject to the other terms of this Section 4.2, the Company shall use its reasonable best efforts to effect, as soon as

6

practicable, the registration under the Securities Act of the resale of all Registrable Securities that the Major Stockholders request to be registered in any Registration Request and/or the underwritten offering of all Registrable Securities that the Major Stockholders request to be offered pursuant to any Underwriting Request. With respect to any Registration Request, the Company shall use its reasonable best efforts to cause any related Registration Statement to be declared effective under the Securities Act as promptly as practicable after the filing thereof and to keep such Registration Statement effective until the participating Major Stockholder or Major Stockholders and their respective Affiliates, as the case may be, have completed the distribution described in such Registration Statement. Any Major Stockholder exercising its rights in accordance with this Section 4.2 may request that the Company register the resale or effect an offering of such Registrable Securities on an appropriate form, including a Shelf Registration Statement (so long as the Company is eligible to use Form S-3). The Company’s obligations pursuant to this Section 4.2 shall be subject to the following limitations and conditions:

(i) the Company shall not be required to comply with any Offering Request that is received within ninety (90) calendar days after the closing of any underwritten offering effected by one or more Major Stockholders or the Company;

(ii) the Company shall not be required to comply with any Offering Request where the anticipated aggregate offering price of all Registrable Securities requested to be registered or offered by the Major Stockholder (together with any related requests of other Major Stockholders) is less than fifty million dollars ($50,000,000), unless the remaining Registrable Securities of the Major Stockholder, together with the remaining Registrable Securities of its Affiliates, have an aggregate value less than such amount, in which case such Major Stockholder may make a single and final request with respect to the remaining Registrable Securities of itself and its Affiliates;

(iii) the Company shall not be required to comply with any Offering Request, and may suspend its obligations under this Section 4.2, as applicable, for the duration of any applicable Blackout Period, following its delivery of written notice thereof to the Major Stockholders;

(iv) the Company shall not be required to comply with any Registration Request at any time that the Shelf Registration Statement is effective; and

(v) the Company shall be entitled to postpone any Offering Request if, in the good faith determination of the Board of Directors, it is not feasible for the Company to proceed with the Offering Request because audited or pro forma financial statements that are required by the Securities Act to be included in any related registration statement or prospectus are then unavailable, until such time as such financial statements are completed or obtained by the Company, provided that the Company shall use its reasonable best efforts to complete or obtain such financial statements as promptly as practicable.

(b) Demand Procedures.

(i) Any Offering Request shall specify: (i) the approximate aggregate number of Registrable Securities requested to be registered or offered for sale in such Offering Request, (ii) the intended method of disposition in connection with such Offering Request, to the extent then known and (iii) the identity of the Major Stockholder or Major Stockholders making such Offering Request.

7

(ii) In connection with any Offering Request, the Major Stockholder(s) making such Offering Request and Company management shall jointly participate in the process of selecting the investment banking firms that will serve as lead and co-managing underwriters with respect to such underwritten offering. In addition, the Company (together with all Holders proposing to distribute their securities through such underwriting) shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwritten offering. Notwithstanding any other provision of this Section 4.2, if the managing underwriter(s) advise the Major Stockholder(s) in writing that marketing factors require a limitation of the number of shares to be underwritten in a Major Stockholder-initiated registration or offering, the Company shall so advise all Major Stockholders that own Registrable Securities or whose Affiliates own Registrable Securities, that, in any such case, would otherwise be underwritten pursuant hereto, and the number of shares of Registrable Securities that may be included in the registration and underwriting shall be allocated as follows:

(A) first, among all Major Stockholders and their respective Affiliates, as the case may be, in proportion, as nearly as practicable, to the respective amounts of Registrable Securities requested by such Major Stockholders to be included in the registration or underwritten offering;

(B) second, to the Company; and

(C) third, if there remains availability for additional securities to be included in such registration or underwritten offering, among any other Persons who have been granted registration rights, and have validly requested participation in such registration or underwritten offering, in proportion, as nearly as practicable, to the respective amounts of additional securities of such other Persons to be included in the registration or underwritten offering.

To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Major Stockholder or its Affiliates, as applicable, to the nearest 100 shares.

(iii) For purposes of this Section 4.2, a registration shall not be counted as “effected” if, as a result of an exercise of the underwriter’s cutback provision in Section 4.2(b)(ii), fewer than fifty percent (50%) of the total number of Registrable Securities that Major Stockholders have requested to be included in such registration statement are actually included.

4.3 Piggyback Rights.

(a) General. If, at any time or from time to time after the date hereof, the Company proposes to register the sale of any of its securities or conduct an offering of registered securities for its own account or for the account of any third Person (including any Major Stockholder(s) or its Affiliate(s) pursuant to this Agreement) on a form which would permit the registration or offering of Registrable Securities (other than (a) pursuant to a registration

statement on Form S-8 or S-4 or any similar or successor form, (b) in connection with a registration the primary purpose of which is to register debt securities (i.e., in connection with a so-called “equity kicker”) or (c) in connection with a public offering by the Company in which the Company has received the prior written consent of Stockholders holding in the aggregate a majority of the number of Registrable Securities held by Stockholders other than Major Stockholders that no Registrable Securities will be included in such public offering), except as otherwise provided herein, the Company will:

(i) promptly give written notice thereof to each Stockholder that owns Registrable Securities with a gross anticipated offering price equal to or greater than five million dollars ($5,000,000) and would otherwise be entitled to exercise piggyback or participation rights in accordance with Section 4.3(d); provided that any Stockholder may deliver written notice (an “Opt-Out Notice”) to the Company requesting that such Stockholder not receive notice from the Company of any proposed registration or offering; provided further that following receipt of an Opt-Out Notice from a Stockholder (unless subsequently revoked by such Stockholder in writing), the Company shall not be required to deliver any notice pursuant to this Section 4.3(a)(i) and such Stockholder shall no longer be entitled to participate in any registration or offering conducted pursuant to this Section 4.3; and

(ii) include in such registration or offering, all the Registrable Securities specified in a written request or requests, made within seven (7) calendar days after delivery of such written notice from the Company, by any Stockholders (except that (A) if the managing underwriter(s) or the Person initiating the registration or offering determine that marketing factors require a shorter time period and so inform each Stockholder in the applicable written notice, such written request or requests must be made within three (3) calendar days and (B) in the case of an “overnight” offering or a “bought deal,” such written request or requests must be made within one (1) Business Day), in any case subject to the requirements of Section 4.2(b) or Section 4.3(b), as applicable, including without limitation the priorities set forth therein; provided, however, that the Company may withdraw any registration or offering initiated by the Company at any time before any related registration statement becomes effective, or postpone or terminate any offering of securities under such registration statement initiated by the Company, without obligation or liability to any Stockholder. The Company shall not have to provide notice of any new registration of securities proposed by the Company to the extent the Registrable Securities of the Stockholders are already included in an effective Shelf Registration Statement. Additionally, the Company shall not have to provide notice of any registration of securities proposed by the Company to any Stockholder to the extent such Stockholder does not hold a sufficient number of Registrable Securities to meet the minimum participation level set forth in Section 4.3(d) of this Agreement. The absence of any requirement to provide such notice shall have no effect on the rights of any Stockholder to participate in any offering following such registration in accordance with the terms of this Agreement.

(b) Underwriting. Notwithstanding any other provision of this Section 4.3, if the managing underwriter(s) determine that marketing factors require a limitation of the number of shares to be underwritten in a Company-initiated registration or offering, the Company shall so advise all Holders whose securities would otherwise be registered or offered pursuant hereto, and the number of shares of Registrable Securities that may be included in the registration or underwritten offering shall be so limited and, except as otherwise provided herein, shall be allocated as follows:

9

(i) first, to the Company;

(ii) second, if there remains additional availability for additional Registrable Securities to be included in such registration or underwritten offering, among all Holders in proportion, as nearly as practicable, to the respective amounts of Registrable Securities requested by such Holders to be included in the registration or underwritten offering; and

(iii) third, if there remains availability for additional securities to be included in such registration or underwritten offering, pro rata among any other Persons who have been granted registration rights, and have validly requested participation in such registration or underwritten offering, in proportion, as nearly as practicable, to the respective amounts of additional securities of such other Persons to be included in the registration or underwritten offering.

(c) Withdrawal. If any Holder disapproves of the terms of any underwriting related to any underwritten offering effected pursuant to Section 4.2 or this Section 4.3, the Holder may elect to withdraw therefrom by written notice to the Company and the managing underwriter(s). If by the withdrawal of such Registrable Securities a greater number of shares of Registrable Securities held by other Holders may be included in such registration (up to the maximum of any limitation imposed by the managing underwriter(s)), then the Company shall offer to all Holders who have included Registrable Securities in the registration or underwritten offering the right to include additional shares of Registrable Securities in the same proportion used in determining the participation limitation in Section 4.2(b) or Section 4.3(b).

(d) Minimum Participation Level; Stockholders Declining to Participate in Shelf Registration. To the extent a Stockholder has Registrable Securities included in an effective Shelf Registration Statement, such Stockholder may not exercise its piggyback or participation rights pursuant to this Section 4.3 unless such Stockholder requests the inclusion of Registrable Securities in the applicable registration or underwritten offering with a gross anticipated offering price that is equal to or greater than five million dollars ($5,000,000). In addition, no Stockholder who has been offered but has declined the opportunity to include such Stockholder’s Registrable Securities in a Shelf Registration Statement will be entitled to receive any notices under this agreement or exercise piggyback or participation rights pursuant to this Section 4.3.

4.4 Other Registration-Related Matters.

(a) The Company may require any Stockholder that owns Shares that are included, or that such Stockholder has requested to be included, in a registration or offering in accordance with this Agreement (each a “Holder”) to furnish to the Company in writing such information regarding such Holder and the distribution of the Shares which are included in a public offering as may from time to time reasonably be requested in writing in order to comply with the Securities Act; provided, however, that under no circumstances will any Holder be obligated to make representations or provide indemnities except with respect to information reasonably required with respect to itself, the securities proposed to be sold by it and the intended method of disposition of such securities by such Holder, or such other representations as required by law.

10

(b) The Company will pay all expenses in connection with each registration or proposed registration of Registrable Securities pursuant to Article 4 and the reasonable fees and expenses of one counsel for all Holders selected by the Holders of the majority of the Registrable Securities included by such Holders in such registration.

(e) In the event that any Holder could reasonably be deemed to be an “underwriter” (as defined in Section 2(a)(11) of the Securities Act) in connection with such Registration Statement and any amendment or supplement thereof, reasonably cooperate with such Holder in allowing such Holder to conduct customary “underwriter’s due diligence” with respect to the Company and satisfy the Holder’s obligations in respect thereof.

(f) Each Holder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 4.4(c)(ix), such Holder will forthwith discontinue disposition of securities pursuant to the Registration Statement covering such Registrable Securities until such Holder’s receipt of the copies of the amended or supplemented Prospectus contemplated by Section 4.4(c)(ix) and, if so directed by the Company, such Holder will deliver to the Company (at the Company’s expense) all copies, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Registrable Securities current at the time of receipt of such notice. In the event the Company gives any such notice, the period for which the Company will be required to keep the registration statement effective will be extended by the number of days during the period from and including the date of the giving of such notice pursuant to Section 4.4(c)(ix) to and including the date when each Holder has received the copies of the supplemented or amended prospectus contemplated by Section 4.4(c)(ix).

(g) Each Stockholder, other than the AS Group, who, along with its Affiliates, holds Registrable Securities in amount greater than the amount specified in Section 4.3(a)(i) shall agree in connection with any Underwritten Offering not to effect any sale, disposition or distribution of Registrable Securities or other equity securities of the Company during the 90-day period beginning on the date a prospectus or prospectus supplement relating to the such underwritten offering is filed with under the Securities Act, provided that (i) the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction generally imposed by the underwriters on the Company or the officers, directors or any other equityholder of the Company on whom a restriction is imposed and (ii) the restrictions set forth in this Section 4.4(g) shall not apply to any Registrable Securities that are included in such underwritten offering.

4.5 Indemnification.

(a) Indemnification by the Company. In the event of any registration of any securities of the Company under the Securities Act pursuant to Article 4, the Company hereby agrees to indemnify and hold harmless, to the extent permitted by law, each Holder of Registrable Securities covered by such Registration Statement, each Affiliate of such Holder and their respective directors and officers, general and limited partners or members and managing members (and the directors, officers, affiliates and controlling Persons thereof), and each other Person, if any, who controls such Holder within the meaning of the Securities Act (collectively, the “Indemnified Parties”), against any and all losses, claims, damages or liabilities, joint or several, and expenses to which such Indemnified Party may become subject under the Securities

14

Act, common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof, whether or not such Indemnified Party is a party thereto) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement under which such securities were registered under the Securities Act, any Prospectus, preliminary Prospectus, free writing prospectus (as defined in Rule 405 promulgated under the Securities Act) or any amendment thereof or supplement thereto, (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, or (iii) any violation or alleged violation by the Company of the Securities Act or any other similar federal or state securities laws or any rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance; and the Company will reimburse such Indemnified Party for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, liability, action or proceeding; provided, that the Company will not be liable to any Indemnified Party in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement, in any such Prospectus, preliminary Prospectus, free writing prospectus (as defined in Rule 405 promulgated under the Securities Act) or any amendment thereof or supplement thereto, in reliance upon and in conformity with written information with respect to such Indemnified Party furnished to the Company by such Indemnified Party for use in the preparation thereof. Such indemnity will remain in full force and effect regardless of any investigation made by or on behalf of such Holder or any Indemnified Party and will survive the Transfer of such securities by such Holder.

(b) Indemnification by the Holders. The Company may require, as a condition to including any Registrable Securities in any registration statement filed in accordance with Article 4, that the Company shall have received an undertaking reasonably satisfactory to it from the Holder of such Registrable Securities to indemnify and hold harmless (in the same manner and to the same extent as set forth in Section 4.5(a)) the Company, all other Holders and any prospective underwriter, as the case may be, and any of their respective Affiliates, directors, officers, general and limited partners, members and managing members and controlling Persons, with respect to any statement or alleged statement in or omission or alleged omission from such Registration Statement, any Prospectus, preliminary Prospectus, free writing prospectus (as defined in Rule 405 promulgated under the Securities Act) or any amendment thereof or supplement thereto, if such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with written information with respect to such Holder furnished to the Company by such Holder expressly for use in the preparation of such Registration Statement, Prospectus, preliminary Prospectus, free writing prospectus (as defined in Rule 405 promulgated under the Securities Act) or any amendment thereof or supplement thereto, or a document incorporated by reference into any of the foregoing; provided, however, that each Holder’s obligation to indemnify hereunder shall be several, not joint and several, and each Holder’s aggregate liability hereunder and under Section 4.5(e) with respect to any particular registration shall be limited to an amount equal to the net proceeds received by such Holder from the Registrable Securities sold by such Holder in such registration. Such indemnity will remain in full force and effect regardless of any investigation made by or on behalf of the Company or any of the Holders, or any of their respective affiliates, directors, officers or controlling Persons and will survive the Transfer of such securities by such Holder.

15

(c) Notices of Claims, Etc. Promptly after receipt by an Indemnified Party hereunder of written notice of the commencement of any action or proceeding with respect to which a claim for indemnification may be made pursuant to this Section 4.5 such Indemnified Party will, if a claim in respect thereof is to be made against an Indemnifying Party, give written notice to the latter of the commencement of such action; provided, that the failure of the Indemnified Party to give notice as provided herein will not relieve the indemnifying party of its obligations under Section 4.5(a) or 4.5(b), except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action is brought against an Indemnified Party, unless in such Indemnified Party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist in respect of such claim, the indemnifying party will be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such Indemnified Party, and after notice from the indemnifying party to such Indemnified Party of its election so to assume the defense thereof, the indemnifying party will not be liable to such Indemnified Party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof other than reasonable costs of investigation. If, in such Indemnified Party’s reasonable judgment, having common counsel would result in a conflict of interest, between the interests of such indemnified and indemnifying parties, then such Indemnified Party may employ separate counsel reasonably acceptable to the indemnifying party to represent or defend such Indemnified Party in such action, it being understood, however, that the indemnifying party will not be liable for the reasonable fees and expenses of more than one separate firm of attorneys at any time for all such Indemnified Parties (and not more than one separate firm of local counsel at any time for all such Indemnified Parties) in such action. No indemnifying party will consent to entry of any judgment or enter into any settlement which 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 of such claims or litigation. No Indemnified Party will consent to entry of any judgment or enter into any settlement without the consent of the indemnifying party (which will not be unreasonably withheld).

(d) Other Indemnification. Indemnification similar to that specified in this Section 4.5 (with appropriate modifications) will be given by the Company and each Holder of Registrable Securities with respect to any required registration or other qualification of securities under any federal or state law or regulation or governmental authority other than the Securities Act.

(e) Contribution. In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in this Section 4.5 is unavailable to an Indemnified Party, the indemnifying party shall contribute to the aggregate losses, damages, liabilities and expenses (collectively, “Losses”) of the nature contemplated by such indemnity agreement incurred by any Indemnified Party, (i) in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and the Indemnified Parties on the other, in connection with the statements or omissions which resulted in such Losses or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such

16

proportion as is appropriate to reflect not only the relative fault of but also the relative benefits to the Company on the one hard and each such Indemnified Party on the other, in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations. The relative benefits to the indemnifying party and the Indemnified Party shall be determined by reference to, among other things, the total proceeds received by the indemnifying party and the Indemnified Party in connection with the offering to which such losses relate. The relative fault of the indemnifying party and the Indemnified Party shall be determined by reference to, among other things, whether the action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or related to information supplied by, the indemnifying party or the Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action. The parties hereto agree that it would be not be just or equitable if contribution pursuant to this Section 4.5(e) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 4.5(e), the aggregate liability of any indemnifying party under this Section 4.5(e) and Section 4.5(b) shall be limited to an amount equal to the amount of net proceeds received by such indemnifying party from sales of the Registrable Securities by such indemnifying party pursuant to the offering that gave rise to such Losses.

4.6 Participation in Underwritten Registrations. No Person may participate in any registration hereunder which is underwritten unless such Person (a) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements; provided that no holder of Registrable Securities included in any underwritten registration shall be required to make any representations or warranties to the Company or the underwriters (other than representations and warranties regarding such holder, such holder’s ownership of its shares of Common Stock to be sold in the offering and such holder’s intended method of distribution) or to undertake any indemnification obligations to the Company or the underwriters with respect thereto, except as otherwise provided in Section 4.5.

4.7 Rule 144 Compliance. With a view to making available to Stockholders holding of Registrable Securities the benefits of Rule 144 under the Securities Act and any other rule or regulation of the SEC that may at any time permit a Stockholder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3 (or any successor form), the Company shall:

(a) make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times after the effective date of the registration statement filed by the Company for its initial public offering;

(b) use its reasonable best efforts to file with the SEC 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 the Company has become subject to such reporting requirements; and

17

(c) furnish to any Stockholder so long as such Stockholder owns Registrable Securities, promptly upon request, a written statement by the Company as to its compliance with the reporting requirements of Rule 144 under the Securities Act and of the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed or furnished by the Company as such Stockholder may request in connection with the sale of Registrable Securities without registration.

4.8 Preservation of Rights. The Company shall not (a) grant any registration rights to third parties which are more favorable than or inconsistent with the rights granted hereunder, or (b) enter into any agreement, take any action, or permit any change to occur, with respect to its securities that violates or subordinates the rights expressly granted to the holders of Registrable Securities in this Agreement, except, in each case, if approved by (i) Stockholders holding in the aggregate a majority of the number of Registrable Securities held by Stockholders and (ii) the AS Group for so long as the AS Group holds at least ten percent (10%) of the aggregate number of outstanding Registrable Securities.

4.9 Termination of Registration Rights. Except with respect to the rights provided for in Section 4.5, no Stockholder shall be entitled to exercise any right provided for in this Article 4 after the date on which such Stockholder no longer holds any Registrable Securities.

ARTICLE 5. TERM OF AGREEMENT

5.1 Termination of this Agreement. This Agreement shall remain in effect until terminated automatically (i) upon the sale of all or substantially all of the assets or equity interests in the Company to a third party whether by merger, consolidation, sale of assets or securities or otherwise, or (ii) upon the cessation of the Company’s business and winding up of its affairs. Notwithstanding any termination of this Agreement, however, the provisions of this Agreement shall survive any such termination to the extent necessary for any Person to enforce any right of such Person which accrued hereunder prior to or on account of such termination.
