Section 2.1

Shelf Registration.

(a) Automatic Shelf Registration Statement. The Company shall file with the Commission, as soon as practicable, but in any event within ten days after the Effective Time, the Automatic Shelf Registration Statement, which shall become effective upon filing with the Commission pursuant to Rule 462(e) under the Securities Act and contain a prospectus in such form to permit (x) each Stockholder to sell its Registrable Securities and (y) each lender to whom any Global Stockholder has pledged or pledges any of its Registrable Securities to sell such Registrable Securities in the event the applicable borrower or pledging Global Stockholder defaults under the applicable credit agreement, in each case, at any time beginning on or after the filing thereof with the Commission pursuant to Rule 415 under the Securities Act or any successor or similar rule that may be adopted by the Commission. If the Company is not eligible to use an automatic shelf registration statement at any time of determination of eligibility, the Company shall promptly (but in any event within 30 days) post-effectively amend the Automatic Shelf Registration Statement or file a new registration statement on a Form S-3, in either case so to permit (x) each Stockholders to sell its Registrable Securities and (y) each lender to whom any Global Stockholder has pledged or pledges any of its Registrable Securities to sell such Registrable Securities in the event the applicable borrower or pledging Stockholder defaults under the applicable credit agreement, in each case, pursuant to Rule 415 under the Securities Act or any successor or similar rule that may be adopted by the Commission. The term “Shelf Registration Statement” as used herein shall mean the Automatic Shelf Registration Statement or any post-effective amendment thereto or a new registration statement so filed pursuant to this Section 2.1. Upon any Shelf Registration Statement having been filed:

(i) the Company shall use its reasonable best efforts to keep such Shelf Registration Statement continuously effective (including by filing any necessary post-effective amendments to such Shelf Registration Statement or a new Shelf Registration Statement) until the earlier of (x) the date on which all the Registrable Securities covered by such Shelf Registration Statement have been sold thereunder, (y) such time as the Registrable Securities covered by such Shelf Registration Statement are no longer outstanding or otherwise no longer constitute Registrable Securities and (z) the date that is three years from the date of filing of such Shelf Registration Statement; and

(ii) the Company shall pay the registration fee for all the Registrable Securities at the time of filing of the Automatic Shelf Registration Statement and shall not elect to pay any portion of the registration fee on a deferred basis.

(b) Shelf Demand Notice. Subject to the limitations set forth in Section 2.3, if at any time following the filing of any Shelf Registration Statement, one or more Stockholders desire to sell all or any portion of the Registrable Securities under such Shelf Registration Statement in an Underwritten Offering (any such sale, a “Shelf Demand Offering”), such Stockholders shall (i) notify (such notice, the “Shelf Demand Notice”) the Company of such intent at least 15 days prior to such proposed sale (or, in the case of a Shelf Demand Offering that does not involve a “road show”, at least three days prior to such proposed sale), and (ii) simultaneously with delivery of the Shelf Demand Notice to the Company, deliver written notice of such Shelf Demand Offering to each other Global Stockholder that is a Stockholder on the date that such Shelf Demand Notice is delivered to the Company. Notwithstanding the foregoing, the Shelf Demand Notice for the Initial Marketed Secondary Offering may be given on the first business day following the Effective Time and, in such case, each of the parties hereto agrees to use its reasonable best efforts to commence the Initial Marketed Secondary Offering within 30 days of the Effective Time; provided that the Initial Marketed Secondary Offering shall be for the sale of Registrable Securities with an aggregate market value of at least $600 million measured at the closing trading price on the date such notice is given. Each Shelf Demand Offering (other than the Initial Marketed Secondary Offering) shall be for the sale of an amount of Registrable Securities equal to or greater than the Registrable Amount. The Shelf Demand Notice shall: (1) specify (x) the aggregate number of Registrable Securities requested to be registered in such Shelf Demand Offering and (y) the identity of the Stockholder or Stockholders requesting such Shelf Demand Offering and (2) provide a representation from the proposed selling Stockholders that all the shares proposed for sale under such Shelf Demand Offering constitute Registrable Securities.

(c) Shelf Demand Offering. Subject to Section 2.3(b), the Company shall include in the Shelf Demand Offering covered by such Shelf Demand Notice all Registrable Securities of each Global Stockholder and its Related Stockholders with respect to which the Company has received a written request for inclusion therein from any Global Stockholder within five days (or, in the case of any Shelf Demand Notice that does not involve a “road show”, within two days) after the Company has received the Shelf Demand Notice, which written request shall comply with the requirements applicable to a Shelf Demand Notice set forth in the last sentence of such clause (b). The Company shall prepare and file a prospectus

supplement, post-effective amendment to the Shelf Registration Statement and/or Exchange Act reports incorporated by reference into the Shelf Registration Statement and take such other actions as necessary or appropriate to permit the consummation of such Shelf Demand Offering, including, subject to Section 2.3(a), conducting a “road show”, if requested by such Stockholders. In the case of a Shelf Demand Offering that does not involve a “road show”, the Company shall take all actions to enable the Stockholders with respect to which the Company has received a written request for inclusion in such offering in accordance with the first sentence of this clause (c) to price such offering within three days of receipt of the Shelf Demand Notice; provided, that if a “comfort” letter is required in connection with the pricing of such offering, and the Company was unable to obtain such “comfort” letter within three days of receipt of such Shelf Demand Notice, then the Company shall use its reasonable best efforts to obtain such “comfort” letter and price such offering as soon as reasonably practicable. The Stockholders having notified or directed the Company to commence a Shelf Demand Offering or to include any of their Registrable Securities therein shall have the right to withdraw such notice or direction by giving written notice to the Company prior to the commencement of a “road show” and such withdrawal will not count towards the limitation in Section 2.3(a); provided, however, that (i) any Shelf Demand Offering for which a “road show” has been conducted shall count towards such limitation, regardless of whether such Shelf Demand Offering is consummated, unless such Shelf Demand Offering is not consummated due to a Suspension Period, and (ii) the Stockholders shall reimburse the Company for all reasonable fees and expenses incurred by the Company or paid by the Company on behalf of the Stockholders pursuant to Section 2.8, in each case incurred in connection with such Shelf Demand Offering.

(d) Suspension of Shelf Registration Statement. Notwithstanding anything to the contrary contained in this Agreement, the Company shall be entitled, from time to time, by providing written notice to the Global Stockholders, to require the Stockholders to suspend the use of the prospectus for sales of Registrable Securities under the Shelf Registration Statement for a reasonable period of time not to exceed 60 days in succession or 105 days in the aggregate in any 12 month period (a “Suspension Period”), if (i) the Board determines in good faith and in its reasonable judgment that the effectiveness and use of such Shelf Registration Statement would cause the disclosure of material, non-public information that the Company has a bona fide business purpose for preserving as confidential or (ii) the Company determines that it does not have all requisite audited and other financial information publicly available and such financial information not then publicly available contains material information. Immediately upon receipt of such notice, the Stockholders covered by the Shelf Registration Statement shall discontinue the disposition of Registrable Securities under such Shelf Registration Statement until the requisite changes to the prospectus have been made as required below. Any Suspension Period shall terminate at such time as the public disclosure of such information is made or the requisite financial information becomes publicly available, as applicable. After the expiration of any Suspension Period and without any further request from a Stockholder, the Company shall as promptly as reasonably 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.

Section 2.2

Demand Registration.

(a) Registration. At any time following the Effective Time, except at any time during which a Shelf Registration Statement pursuant to Section 2.1 is effective, available for the offer and sale of Registrable Securities (without giving effect to any Suspension Period) and not subject to any stop order, injunction, or other order or requirement of the Commission or other governmental agency or court (such period, a “Shelf Effectiveness Period”), one or more Stockholders (each, a “Requesting Stockholder”) shall be entitled to make a written request of the Company (a “Demand”) to effect the registration under the Securities Act of an amount of Registrable Securities equal to or greater than the Registrable Amount (such registration, a “Demand Registration”). A Stockholder making a Demand shall simultaneously deliver written notice of such Demand to each other Global Stockholder that is a Stockholder on the date that such Demand is delivered to the Company. Upon such Demand, the Company will, subject to Section 2.3(b) and the other the terms of this Agreement, use its reasonable best efforts to effect the registration under the Securities Act of:

(i) the Registrable Securities that the Company has been so requested to register by the Requesting Stockholder or Requesting Stockholders in such Demand;

(ii) all other Registrable Securities that the Company has been requested to register pursuant to Section 2.2(b); and

(iii) all shares of Common Stock that the Company may elect to register (such shares, “Company Common Stock”) in connection with any offering of Registrable Securities pursuant to Section 2.3(b);

all to the extent necessary to permit the disposition (in accordance with the intended method of disposition stated in such Demand) of the Registrable Securities and the additional Company Common Stock, if any, to be so registered.

(b) Demands. A Demand shall: (i) specify (A) the aggregate number of Registrable Securities requested to be registered in such Demand Registration, (B) the intended method of disposition in connection with such Demand Registration, to the extent then known, and (C) the identity of the Requesting Stockholder or Requesting Stockholders, and (ii) provide a representation from the proposed selling Stockholders that all such shares proposed for sale under such Demand Registration constitute Registrable Securities. Subject to Section 2.3(b), the Company shall include in the Demand Registration covered by such Demand all Registrable Securities of each Global Stockholder and its Related Stockholders with respect to which the Company has received a written request for inclusion therein from any Global Stockholder within five days after the Company has received a Demand, which written request shall comply with the requirements applicable to a Demand set forth in the first sentence of this clause (b).

(c) Effective Registration Statement. A Demand Registration shall not be deemed to have been effected and shall not count as a Demand (i) unless a registration statement with respect thereto has become effective and has remained effective for a period of at least 60 days (or such shorter period in which all the Registrable Securities included in such Demand

Registration have actually been sold thereunder), (ii) if, after the registration statement with respect thereto has become effective, but prior to such 60th day or the last day of such shorter period described in clause (i) above, such Demand Registration becomes subject to any stop order, injunction or other order or requirement of the Commission or other governmental agency or court for any reason, or (iii) if the conditions to closing specified in the purchase agreement or underwriting agreement entered into in connection with such Demand Registration are not satisfied, other than solely by reason of some act or omission by such Requesting Stockholders; provided, however, that, notwithstanding the foregoing, (A) should a registration statement with respect to a Demand Registration not become effective due to the failure of the Requesting Stockholder to perform its obligations under this Agreement in any material respect or (B) should a Demand Registration that is an Underwritten Offering for which a “road show” is conducted not be consummated, the related request shall count as a Demand.

(d) Registration Statement Form. Demand Registrations shall be on Form S-3 (or any successor form) or, if the Company is not eligible to use Form S-3, another form reasonably selected by the Company as appropriate for such Demand Registration and reasonably acceptable to the Requesting Stockholder or Requesting Stockholders.

(e) Restrictions on Demand Registrations. The Company shall not be obligated to (i) maintain the effectiveness of a registration statement under the Securities Act, filed pursuant to a Demand Registration, for a period longer than 60 days or (ii) effect any Demand Registration (A) within six months of a “firm commitment” Underwritten Offering in which all Stockholders were offered “piggyback” rights pursuant to Section 2.4 (subject to Section 2.3(b)) and at least 50% of the number of Registrable Securities requested by such Stockholders to be included in such offering were included, (B) within six months of any other Demand Registration, (C) if a Shelf Registration Statement is effective pursuant to Section 2.1 or (D) if, in the Company’s reasonable judgment, it is not feasible for the Company to proceed with the Demand Registration because of the unavailability of audited or other required financial statements. In addition, the Company shall be entitled to postpone (upon written notice to all Stockholders) for up to 105 days the filing or the effectiveness of a registration statement for any Demand Registration (but no more than twice in any period of 12 consecutive months), if the Board determines in good faith and in its reasonable judgment that the filing or effectiveness of the registration statement relating to such Demand Registration would cause the disclosure of material, non-public information that the Company has a bona fide business purpose for preserving as confidential. In the event of such a postponement by the Company, the holders of a majority of Registrable Securities held by the Requesting Stockholder(s) shall have the right to withdraw such Demand in accordance with Section 2.5.

Section 2.3

Offering Demands.

(a) Number of Offering Demands; Road Shows. In addition to the Initial Secondary Marketed Offering, (x) each of ▇▇▇▇▇▇▇▇▇ and ▇▇▇▇▇▇ shall be entitled to two Offering Demands for itself and/or its Related Stockholders, and (y) Fortress shall be entitled to five Offering Demands for itself and/or its Related Stockholders, which, in the case of clauses (x) and (y), may be Shelf Demand Offerings, Demand Registrations or both. Notwithstanding anything to the contrary herein, (i) the aggregate number of “road shows” the Company shall be required to participate in pursuant to this Agreement shall not exceed six and (ii) the Company

shall not be obligated to participate in any “road show” pursuant to this Agreement within 180 days of any other “road show” in which the Company has participated or will be participating pursuant to this Agreement.

(b) Participation in Offering Demands. The Company may, at its option, include securities other than Registrable Securities in an Offering Demand, provided that the Company provides prompt written notice to the Global Stockholders of its intent to include such securities; provided, however, that if in connection with such Offering Demand any managing underwriter (or, if such Demand Registration is not an Underwritten Offering, a nationally recognized independent investment bank selected by the Stockholders participating in such Offering Demand, in conjunction with the Company, and whose fees and expenses shall be borne solely by the Company) advises the Company, in writing, that, in its opinion, the inclusion of all of the securities, including securities of the Company that are not Registrable Securities, sought to be registered in connection with such Offering Demand would adversely affect the marketability of the Registrable Securities sought to be sold pursuant thereto, then the Company shall include in such registration statement or offering only such securities as the Company is advised by such underwriter (or investment bank) can be sold without such adverse effect as follows and in the following order of priority: (i) first, up to the number of Registrable Securities requested to be included in such Offering Demand by the Stockholders, which, in the opinion of the underwriter (or investment bank) can be sold without such adverse effect, pro rata among such Stockholders requesting such Offering Demand on the basis of the amount of Registrable Securities held by such Stockholders, (ii) second, securities the Company proposes to sell, and (iii) third, all other securities of the Company duly requested to be included in such Offering Demand, pro rata on the basis of the amount of such other securities requested to be included or such other method as determined by the Company.

(c) Selection of Underwriters. Anytime that an Offering Demand involves an Underwritten Offering (including the Initial Marketed Secondary Offering), the Stockholders participating in such offering of Registrable Securities shall mutually select, in conjunction with the Company (with the Company and such Stockholders acting reasonably), the investment banker or investment bankers and managers that will serve as lead and co-managing underwriters with respect to the offering of such Registrable Securities. Notwithstanding the foregoing sentence, the Company hereby acknowledges and agrees that the entities set forth on Schedule 1 hereto (or any of their respective Affiliates) will be acceptable lead or co-managing underwriters with respect to any Offering Demand.

(d) Notices and Requests. Notwithstanding anything to the contrary herein, (i) any Offering Demand made by any Stockholder or any other notice or request provided by any Stockholder, in each case pursuant to this Agreement, shall be made in each case only by Fortress, ▇▇▇▇▇▇▇▇▇ or ▇▇▇▇▇▇, as the case may be, on behalf of such Stockholder, and (ii) if the Company provides any notice required to be given to the Stockholders pursuant to this Agreement to a Global Stockholder, such notice shall be deemed given to such Global Stockholder and its Related Stockholders for purposes of this Agreement.

Section 2.4

Piggyback Registrations.

(a) Right to Piggyback. Subject to the terms and conditions hereof, whenever the Company proposes to register any of its equity securities under the Securities Act (other than a registration by the Company on a registration statement on Form S-4 or a registration statement on Form S-8 or any successor forms thereto), whether for its own account or for the account of other Persons that do not constitute Stockholders, (each such registration, a “Piggyback Registration”), the Company shall give the Global Stockholders prompt written notice thereof (but not less than ten business days prior to the initial filing by the Company with the Commission of the registration statement or prospectus supplement with respect thereto). Such notice (a “Piggyback Notice”) shall specify, at a minimum and as applicable, the number or aggregate dollar amount of equity securities proposed to be registered, the proposed date of filing of such registration statement with the Commission, the proposed means of distribution, the proposed managing underwriter or underwriters (if any and if known) and a good faith estimate by the Company of the proposed minimum offering price of such equity securities. Upon the written request of any Global Stockholder on behalf of any Person that on the date of the Piggyback Notice constitutes a Stockholder (such Person, a “Piggyback Seller”) given within ten days after such Piggyback Notice is received by the Global Stockholders (which request shall (x) specify the number of Registrable Securities then presently intended to be disposed of by such Piggyback Seller and (y) provide a representation from the proposed selling Stockholder that all such shares proposed for sale constitute Registrable Securities), the Company, subject to the terms and conditions of this Agreement, shall use its reasonable best efforts to cause all such Registrable Securities held by Piggyback Sellers with respect to which the Company has received such written requests for inclusion to be included in such Piggyback Registration on the same terms and conditions as the Company’s equity securities being sold in such Piggyback Registration.

(b) Priority on Piggyback Registrations. If, in connection with a Piggyback Registration, any managing underwriter (or, if such Piggyback Registration is not an Underwritten Offering, a nationally recognized independent investment bank selected by the Company) advises the Company in writing that, in its opinion, the inclusion of all the equity securities sought to be included in such Piggyback Registration by (i) the Company, (ii) others who have sought to have equity securities of the Company registered in such Piggyback Registration pursuant to rights to demand (other than pursuant to so-called “piggyback” or other incidental or participation registration rights) such registration (such Persons being “Other Demanding Sellers”), (iii) the Piggyback Sellers and (iv) any other proposed sellers of equity securities of the Company (such Persons being “Other Proposed Sellers”), as the case may be, would adversely affect the marketability of the equity securities sought to be sold pursuant thereto, then the Company shall include in the registration statement applicable to such Piggyback Registration only such equity securities as the Company is so advised by such underwriter can be sold without such an effect, as follows and in the following order of priority:

(i) if the Piggyback Registration relates to an offering for the Company’s own account, then (A) first, such number of equity securities to be sold by the Company as determined by the Company, (B) second, Registrable Securities of Piggyback Sellers, pro rata on the basis of the amount of such

Registrable Securities held by such Piggyback Sellers, and (C) third, other equity securities held by any Other Proposed Sellers; or

(ii) if the Piggyback Registration relates to an offering other than for the Company’s own account, then (A) first, such number of equity securities sought to be registered by each Other Demanding Seller, pro rata in proportion to the number or aggregate dollar amount of securities sought to be registered by all such Other Demanding Sellers, (B) second, other equity securities to be sold by the Company as determined by the Company, (C) third, Registrable Securities of Piggyback Sellers pro rata on the basis of the amount of such Registrable Securities held by such Piggyback Sellers, and (D) fourth, other equity securities held by any Other Proposed Sellers.

(c) Terms of Underwriting. In connection with any Underwritten Offering under this Section 2.4, the Company shall not be required to include a holder’s Registrable Securities in such Underwritten Offering unless such holder accepts the terms of the underwriting as agreed upon between the Company and the underwriters selected by the Company, provided that any such underwriting agreement includes only customary terms and conditions.

(d) Withdrawal by the Company. If, at any time after giving the Piggyback Notice as set forth in Section 2.4(a) and prior to the time the registration statement filed in connection with such Piggyback Registration is declared effective, the Company shall determine for any reason not to register such equity securities, the Company may, at its election, give written notice of such determination to each Stockholder and thereupon shall be relieved of its obligation to register any Registrable Securities in connection with such particular withdrawn or abandoned Piggyback Registration (but not from its obligation to pay the Registration Expenses in connection therewith as provided herein), provided, that Stockholders may continue the registration as a Demand Registration pursuant to the terms of Section 2.2.

(e) Availability of Right to Piggyback. Notwithstanding anything to the contrary in this Section 2.4, during any Shelf Effectiveness Period, the provisions of this Section 2.4 shall only apply in respect of Underwritten Offerings for which a “road show” is conducted.

Section 2.5 Withdrawal Rights. Subject to Sections 2.1(c) and 2.2(c), any Stockholder having notified or directed the Company to include any or all of its Registrable Securities in a registration statement under the Securities Act, shall have the right to withdraw any such notice or direction with respect to any or all of the Registrable Securities designated by it for registration by giving written notice to such effect to the Company prior to the effective date of such registration statement. In the event of any such withdrawal, the Company shall not include such Registrable Securities in the applicable registration and such Registrable Securities shall continue to be Registrable Securities for all purposes of this Agreement. No such withdrawal shall affect the obligations of the Company with respect to the Registrable Securities not so withdrawn; provided, however, that, in the case of a Demand Registration or a Shelf Demand Offering, if such withdrawal shall reduce the number of Registrable Securities sought to be included in such registration below the Registrable Amount, then the Company shall as promptly as practicable give each holder of Registrable Securities sought to be registered notice

to such effect and, within ten days following the mailing of such notice, such holder of Registrable Securities still seeking registration shall, by written notice to the Company, elect to register additional Registrable Securities to satisfy the Registrable Amount or elect that such registration statement not be filed or, if theretofore filed, be withdrawn. During such ten day period, the Company shall not file such registration statement if not theretofore filed or, if such registration statement has been theretofore filed, the Company shall not seek, and shall use commercially reasonable efforts to prevent, the effectiveness thereof. Any registration statement withdrawn or not filed as a result of (a) an election by the Company, (b) in the case of a Demand Registration, an election by the Requesting Stockholders in accordance with the requirements of Section 2.2(c), (c) in the case of a Shelf Demand Offering, an election by the Requesting Stockholders in accordance with the requirements of Section 2.1(c), or (d) an election by the Company subsequent to the effectiveness of the applicable Demand Registration or Shelf Demand Offering registration statement because any post-effective amendment or supplement to the applicable Demand Registration statement contains information regarding the Company that the Company deems adverse to the Company, shall not be counted as a Demand.

Section 2.6 Holdback Agreements. If requested by the managing underwriter in connection with any Underwritten Offering, the Company and each Stockholder agrees not to (a) effect any public sale or distribution (including sales pursuant to Rule 144) of equity securities of the Company, or any securities convertible into or exchangeable or exercisable for such equity securities, or (b) in the case of each Stockholder, request registration of any Registrable Securities, in each case, during any time period reasonably requested by the Company or the Stockholders, as the case may be, with respect to any Underwritten Offering (which time period shall not exceed 90 days or, in the case of any Underwritten Offering for which a “road show” will not be conducted, 45 days), except as part of such registration, provided that neither the Company nor the Stockholders shall be required to comply with a request made pursuant to this Section 2.6 if, after giving effect to such compliance, the aggregate number of days during which the Company has, or the Stockholders have, complied with all such requests would exceed 180 days in any 365-day period. Subject to the time periods set forth above, if requested by the managing underwriter of such Underwritten Offering, each Stockholder agrees to execute an agreement to such effect with the Company consistent with such managing underwriter’s customary form of holdback agreement.

Section 2.7

Registration Procedures.

(a) Registration. Subject to the provisions of Section 2.1, including the Company’s obligation to file the Automatic Shelf Registration Statement and the timing thereof, if and whenever the Company is required to use reasonable best efforts to effect the registration of any Registrable Securities under the Securities Act as provided in Sections 2.1, 2.2 and 2.4 (whether or not pursuant to an Offering Demand), the Company shall as expeditiously as reasonably practicable:

(i) prepare and file with the Commission a registration statement to effect such registration and thereafter use reasonable best efforts to cause such registration statement to become and remain effective pursuant to the terms of this Agreement; provided, however, that the Company may discontinue any registration of its securities that are not Registrable Securities at any time

prior to the effective date of the registration statement relating thereto; provided, further, that before filing such registration statement or any amendments thereto, the Company will furnish to the counsel selected by the holders of Registrable Securities that are to be included in such registration (“Selling Holders”) copies of all such documents proposed to be filed, which documents will be subject to the review of such counsel, and such review to be conducted with reasonable promptness;

(ii) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to (A) keep such registration statement effective, (B) comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement and (C) complete the disposition of such securities in accordance with the intended methods of disposition set forth in such registration statement, in each case (1) in the case of a Shelf Registration Statement filed pursuant to Section 2.1, as set forth in Section 2.1, (2) in the case of a Demand Registration, as set forth in Section 2.2, and (3) in the case of a Piggyback Registration, the expiration of 60 days after such registration statement becomes effective;

(iii) furnish to each Selling Holder and each underwriter, if any, of the securities being sold by such Selling Holder such number of conformed copies of such registration statement and of each amendment and supplement thereto (in each case including all exhibits), such number of copies of the prospectus contained in such registration statement (including each preliminary prospectus and any summary prospectus and each free writing prospectus (as defined in Rule 405 of the Securities Act) (a “Free Writing Prospectus”) utilized in connection therewith) and any other prospectus filed under Rule 424 under the Securities Act, in conformity with the requirements of the Securities Act, and such other documents as such Selling Holder and underwriter, if any, may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities owned by such Selling Holder;

(iv) use reasonable best efforts to register or qualify such Registrable Securities covered by such registration statement under such other securities laws or blue sky laws of such jurisdictions as any Selling Holder and any underwriter of the securities being sold by such Selling Holder shall reasonably request, and take any other action that may be reasonably necessary or advisable to enable such Selling Holder and underwriter to consummate the disposition in such jurisdictions of the Registrable Securities owned by such Selling Holder, except that the Company shall not for any such purpose be required to (A) qualify generally to do business as a foreign corporation in any jurisdiction wherein it would not but for the requirements of this clause (iv) be obligated to be so qualified, (B) subject itself to taxation in any such jurisdiction or (C) file a general consent to service of process in any such jurisdiction;

(v) use reasonable best efforts to cause such Registrable Securities to be listed on each securities exchange on which similar securities issued by the Company are then listed and, if no such securities are so listed, use commercially reasonable efforts to cause such Registrable Securities to be listed on the NYSE, the American Stock Exchange or the NASDAQ Stock Market;

(vi) use reasonable best efforts to cause such Registrable Securities covered by such registration statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the Selling Holder(s) thereof to consummate the disposition of such Registrable Securities;

(vii) in connection with an Underwritten Offering, obtain for each Selling Holder and underwriter:

(1) an opinion of counsel for the Company, covering the matters customarily covered in opinions requested in underwritten offerings and such other matters as may be reasonably requested by such Selling Holder and underwriters, and

(2) a “comfort” letter (or, in the case of any such Person that does not satisfy the conditions for receipt of a “comfort” letter specified in Statement on Auditing Standards No. 72, an “agreed upon procedures” letter) signed by the independent public accountants who have certified the Company’s financial statements included in such registration statement, provided, that this clause (2) shall not apply to any Piggyback Registration, if such letter is not otherwise being furnished to the Company;

(viii) promptly make available for inspection by any Selling Holder, any underwriter participating in any disposition pursuant to any registration statement, and any attorney, accountant or other agent or representative retained by any such Selling Holder or underwriter (collectively, the “Inspectors”), all financial and other records, pertinent corporate documents and properties of the Company (collectively, the “Records”), as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the Company’s officers, directors and employees to supply all information requested by any such Inspector in connection with such registration statement; provided, however, that, unless the disclosure of such Records is necessary to avoid or correct a misstatement or omission in the registration statement or the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction, the Company shall not be required to provide any information under this subparagraph (viii) if (A) the Company believes, after consultation with counsel for the Company, that to do so would cause the Company to forfeit an attorney-client privilege that was applicable to such information or (B) if either (1) the Company has requested and been granted from the Commission confidential treatment of such information

contained in any filing with the Commission or documents provided supplementally or otherwise or (2) the Company reasonably determines in good faith that such Records are confidential and so notifies the Inspectors in writing unless prior to furnishing any such information with respect to clause (A) or (B) above such Selling Holder requesting such information agrees, and causes each of its Inspectors, to enter into a confidentiality agreement on terms reasonably acceptable to the Company and the Inspectors in accordance with marked norms; and provided, further, that each Selling Holder agrees that it will, upon learning that disclosure of such Records is sought in a court of competent jurisdiction, give notice to the Company and allow the Company to, at its expense, undertake appropriate action and to prevent disclosure of the Records deemed confidential;

(ix) promptly notify in writing each Selling Holder and the underwriters, if any, of the following events:

(1) the filing of the registration statement, the prospectus or any prospectus supplement related thereto or any post-effective amendment to the registration statement or any Free Writing Prospectus utilized in connection therewith, and, with respect to the registration statement or any post-effective amendment thereto, when the same has become effective;

(2) any request by the Commission for amendments or supplements to the registration statement or the prospectus or for additional information;

(3) the issuance by the Commission of any stop order suspending the effectiveness of the registration statement or the initiation of any proceedings by any Person for that purpose; and

(4) the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the securities or blue sky laws of any jurisdiction or the initiation or threat of any proceeding for such purpose;

(x) (A) promptly notify each Selling Holder, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, upon discovery that the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and (B) upon such discovery and at the request of any Selling Holder, promptly prepare and furnish to such seller a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, provided, that to the extent the Company

delivers a Material Event Notice to such Selling Holder, such supplement or amendment shall be prepared and furnished within 60 days of such discovery (or within such shorter period that ends upon public disclosure of the material transaction that necessitated such Material Event Notice); provided, however, that, notwithstanding anything to the contrary herein, the Company shall not be permitted to exercise its right to deliver a Material Event Notice more than two times during any 12 month period;

(xi) make every reasonable effort to obtain the withdrawal of any order suspending the effectiveness of such registration statement;

(xii) otherwise use reasonable best efforts to comply with all applicable rules and regulations of the Commission, and make available to Selling Holders, as soon as reasonably practicable, an earnings statement of the Company covering the period of at least 12 months, but not more than 18 months, beginning with the first day of the Company’s first full quarter after the effective date of such registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder;

(xiii) use its reasonable best efforts to assist Stockholders who made a request to the Company to provide for a third party “market maker” for the Common Stock; provided, however, that the Company shall not be required to serve as such “market maker”

(xiv) cooperate with the Selling Holders and the managing underwriter to facilitate the timely preparation and delivery of certificates (which shall not bear any restrictive legends unless required under applicable law) representing securities sold under any registration statement, and enable such securities to be in such denominations and registered in such names as the managing underwriter or such Selling Holders may request and keep available and make available to the Company’s transfer agent prior to the effectiveness of such registration statement a supply of such certificates; and

(xv) subject to Section 2.3(a), have appropriate officers of the Company prepare and make presentations at any “road shows” (including before analysts and rating agencies), take other actions to obtain ratings for any Registrable Securities (if they are eligible to be rated) and otherwise use its reasonable best efforts to cooperate as reasonably requested by the Selling Holders and the underwriters in the offering, marketing or selling of the Registrable Securities, provided that, notwithstanding anything to the contrary herein, the Company and its management shall, to the extent requested by the managing underwriter and subject to Section 2.3(a), participate in such “road shows” in a customary manner.

The Company may require each Selling Holder and each underwriter, if any, to furnish the Company in writing such information regarding each Selling Holder or underwriter and the distribution of such Registrable Securities as the Company may from time to time reasonably

request to complete or amend the information required by such registration statement or comply with applicable laws. In addition, the Company may require each Selling Holder to execute custody arrangements and other customary agreements (other than powers-of-attorney) appropriate to facilitate any offering of Registrable Securities.

(b) Underwriting. Without limiting any of the foregoing, in the event that any offering of Registrable Securities is to be made by or through an underwriter, the Company, if requested by such underwriter, shall enter into an underwriting agreement with a managing underwriter or underwriters in connection with such offering containing representations, warranties, indemnities and agreements customarily included (but not inconsistent with the covenants and agreements of the Company contained herein) by an issuer of common stock in underwriting agreements with respect to offerings of common stock for the account of, or on behalf of, such issuers, and customary in form and substance.

(c) Return of Prospectuses. Each Selling Holder agrees that upon receipt of any notice from the Company of the happening of any event of the kind described in Section 2.7(a)(x)(A), such Selling Holder shall forthwith (i) discontinue such Selling Holder’s disposition of Registrable Securities pursuant to the applicable registration statement and prospectus relating thereto until (A) such Selling Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 2.7(a)(x) or (B) such supplemented or amended prospectus has been filed with the Commission, and (ii) if so directed by the Company, deliver to the Company, at the Company’s expense, all copies, other than permanent file copies, then in such Selling Holder’s possession of the prospectus covering Registrable Securities at the time of receipt of such notice. In the event the Company gives such notice, any applicable 60-day or three-year period during which the applicable registration statement must remain effective pursuant to this Agreement shall be extended by the number of days during the period from the date of giving of such notice to the date when all Selling Holders shall receive such a supplemented or amended prospectus or such prospectus shall have been filed with the Commission.

Section 2.8 Registration Expenses. All expenses incident to the Company’s performance of, or compliance with, its obligations under this Agreement including, without limitation, all (a) registration and filing fees, all fees and expenses of compliance with securities and “blue sky” laws, (b) fees and expenses associated with filings required to be made with the NASD (including, if applicable, the fees and expenses of any “qualified independent underwriter” as such term is defined in Schedule E of the by-laws of the NASD), (c) printing (including, without limitation, expenses of printing certificates for the Registrable Securities in a form eligible for deposit with the Depository Trust Company and of printing prospectuses if the printing of prospectuses is requested by a holder of Registrable Securities) and copying expenses, (d) messenger and delivery expenses and (e) fees and expenses of the Company’s independent certified public accountants and counsel (including, without limitation, with respect to “comfort” letters and opinions) (collectively, the “Registration Expenses”) shall be borne by the Company, regardless of whether a registration is effected; provided, however, that each Selling Holder shall pay (i) its portion of all underwriting discounts, commissions and transfer taxes, if any, relating to the sale of such Selling Holder’s Registrable Securities and (ii) all fees and expenses of its outside counsel incurred in connection with any registration or offering. The Company will pay its internal expenses (including, without limitation, all salaries and expenses

of its officers and employees performing legal or accounting duties, the expense of any annual audit and the expense of any liability insurance) and the expenses and fees for listing the securities to be registered on each securities exchange and included in each established over-the-counter market on which similar securities issued by the Company are then listed or traded.

Section 2.9

Indemnification.

(a) By the Company. The Company agrees to indemnify and hold harmless, to the fullest extent permitted by law, (i) each Selling Holder and its Affiliates, officers, directors, employees, managers, partners and agents (collectively, the “Selling Indemnified Persons”) and (ii) each Person who controls (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act) any such Selling Indemnified Person, in each case, from and against all losses, claims, damages, liabilities and expenses (including reasonable expenses of investigation and reasonable attorneys’ fees and expenses) (collectively, “Losses”) caused by, resulting from or relating to (A) any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus or preliminary prospectus or Free Writing Prospectus or any amendment or supplement thereto or (B) any omission (or alleged omission) of a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case, except insofar as the same are caused by any information furnished in writing to the Company by any Selling Indemnified Persons expressly for use therein. In connection with an Underwritten Offering and without limiting any of the Company’s other obligations under this Agreement, the Company shall also provide customary indemnities to (i) such underwriters and their Affiliates, officers, directors, employees and agents (collectively, the “Underwriter Indemnified Persons”) and (ii) each Person who controls (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act) any such Underwriter Indemnified Person to the same extent as provided above with respect to the indemnification (and exceptions thereto) of the Selling Indemnified Person and the Person controlling such Selling Indemnified Persons. Reimbursements payable pursuant to the indemnification contemplated by this Section 2.9(a) will be made by periodic payments during the course of any investigation or defense, as and when bills are received or expenses incurred.

(b) By the Selling Holders. In connection with any registration statement in which a holder of Registrable Securities is participating, each such Selling Holder will furnish to the Company in writing information regarding such Selling Holder’s ownership of Registrable Securities and its intended method of distribution thereof and, to the extent permitted by law, shall, severally and not jointly, indemnify (i) the Company and its Affiliates, directors, officers, employees and agents (collectively, the “Crown Indemnified Persons”) and (ii) each Person who controls (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act) any such Crown Indemnified Person against all Losses caused by (A) any untrue statement of material fact contained in the registration statement, prospectus or preliminary prospectus or Free Writing Prospectus or any amendment or supplement thereto or (B) any omission of a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, but, in each case, only to the extent that such untrue statement or omission is caused by any information furnished in writing by any Selling Indemnified Person expressly for use therein; provided, however, that each Selling Holder’s obligation to indemnify the Company hereunder shall, to the extent more than

one Selling Holder is subject to the same indemnification obligation, be apportioned between each Selling Holder based upon the net amount received by each Selling Holder from the sale of Registrable Securities, as compared to the total net amount received by all of the Selling Holders of Registrable Securities sold pursuant to such registration statement. Notwithstanding the foregoing, no Selling Holder shall be liable to the Company for amounts in excess of the lesser of (x) such apportionment and (y) the amount received by such holder in the offering giving rise to such liability. In connection with an Underwritten Offering and without limiting any of other obligations of the Selling Holders under this Agreement, the Selling Holders shall also provide customary indemnities to (i) such Underwriter Indemnified Persons and (ii) each Person who controls (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act) any such Underwriter Indemnified Person to the same extent as provided above with respect to the indemnification (and exceptions thereto) of the Company Indemnified Person and the Person controlling such Company Indemnified Persons. Reimbursements payable pursuant to the indemnification contemplated by this Section 2.9(b) will be made by periodic payments during the course of any investigation or defense, as and when bills are received or expenses incurred.

(c) Notice. Any Person entitled to indemnification hereunder shall give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification; provided, however, that the failure to give such notice shall not release the indemnifying party from its obligation, except to the extent that the indemnifying party has been materially prejudiced by such failure to provide such notice on a timely basis.

(d) Defense of Actions. In any case in which any such action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein, and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, assume the defense thereof, 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 (so long as it shall continue to have the right to defend, contest, litigate and settle the matter in question in accordance with this paragraph) be liable to such indemnified party hereunder for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation, supervision and monitoring (unless (i) such indemnified party reasonably objects to such assumption on the grounds that there may be defenses available to it that are different from or in addition to the defenses available to such indemnifying party or (ii) the indemnifying party shall have failed within a reasonable period of time to assume such defense and the indemnified party is or is reasonably likely to be prejudiced by such delay, in either event the indemnified party shall be promptly reimbursed by the indemnifying party for the expenses incurred in connection with retaining separate legal counsel). An indemnifying party shall not be liable for any settlement of an action or claim effected without its consent. The indemnifying party shall lose its right to defend, contest, litigate and settle a matter if it shall fail to diligently contest such matter (except to the extent settled in accordance with the next following sentence). No matter shall be settled by an indemnifying party without the consent of the indemnified party, which consent shall not be unreasonably withheld (it being understood that the indemnified party shall not be deemed to be unreasonable in withholding its consent if the proposed settlement imposes any obligation on the indemnified party other than the payment of money).

(e) Survival. The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified Person and will survive the transfer of the Registrable Securities and the termination of this Agreement.

(f) Contribution. If recovery is not available under the foregoing indemnification provisions for any reason or reasons other than as specified therein, any Person who would otherwise be entitled to indemnification by the terms thereof shall nevertheless be entitled to contribution with respect to any Losses with respect to which such Person would be entitled to such indemnification but for such reason or reasons. In determining the amount of contribution to which the respective Persons are entitled, there shall be considered the Persons’ relative knowledge and access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission, and other equitable considerations appropriate under the circumstances. It is hereby agreed that it would not necessarily be equitable if the amount of such contribution were determined by pro rata or per capita allocation. 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 found guilty of such fraudulent misrepresentation. Notwithstanding the foregoing, no Selling Holder or transferee thereof shall be required to make a contribution in excess of the net amount received by such holder from its sale of Registrable Securities in connection with the offering that gave rise to the contribution obligation.

(g) Request for Information. Not less than five business days before the expected filing date of each registration statement pursuant to this Agreement, the Company shall notify each Stockholder who has timely provided the requisite notice hereunder entitling the Stockholder to register Registrable Securities in such registration statement of the information, documents and instruments from such Stockholder that the Company or any underwriter reasonably requests in connection with such registration statement, including, but not limited to, a questionnaire, custody agreement, power of attorney, lock-up letter and underwriting agreement (the “Requested Information”). If the Company has not received, on or before the second day before the expected filing date, the Requested Information from such Stockholder, the Company may file the Registration Statement without including Registrable Securities of such Stockholder. The failure to so include in any registration statement the Registrable Securities of a Stockholder (with regard to that registration statement) shall not in and of itself result in any liability on the part of the Company to such Stockholder.

Section 2.10 No Grant of Future Registration Rights. The Company shall not grant any shelf, demand, piggyback or incidental registration rights that are senior to the rights granted to the Stockholders hereunder to any other Person without the prior written consent of a majority (based on the number of Registrable Securities held) of the Stockholders.
