REGISTRATION RIGHTS

Section 2.1 (a) Piggyback Rights. If at any time the Company proposes to register Securities for public sale (whether proposed to be offered for sale by the Company or by any other Person) under the Securities Act (other than a registration on Form S-4 or S-8, or any successor or other forms promulgated for similar purposes or a registration relating to a convertible debt offering) in a manner which would permit registration of Registrable Securities for sale to the public under the Securities Act or any shelf takedown (whether pursuant to Section 2.2(g) or at the initiative of the Company) or sale pursuant to the exercise of any demand rights by any other holders of shares of Common Stock, it will give prompt written notice (which notice shall specify the intended method or methods of disposition) to the Holders of its intention to do so and of such Holder’s rights under this Section 2.1 (a “Piggyback Registration”). Upon the written request of any Holder made within fifteen (15) days after the receipt of any such notice (which request shall specify the number of Registrable Securities intended to be disposed of by such Holder), the Company will use its reasonable efforts to effect the registration under the Securities Act of all Registrable Securities which the Holders have so requested to be registered; provided that: (i) if, at any time after giving written notice of its intention to register any Securities and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to proceed with the proposed registration of the Securities to be sold by it, the Company may, at its election, give written notice of such determination to the Holders and, thereupon, the Company shall be relieved of its obligation to register any Registrable Securities in connection with such registration (but not from its obligation to pay the Registration Expenses incurred in connection therewith) without prejudice to the rights of a Demand Party to

5

request that such registration be effected as a registration under Section 2.2(g)(ii); and (ii) if such registration involves an Underwritten Offering, the Holders of Registrable Securities requesting to be included in the registration must, upon the written request of the Company, sell their Registrable Securities to the underwriters on the same terms and conditions as apply to the other Securities being sold through underwriters under such registration, with, in the case of a combined primary and secondary offering, only such differences, including any with respect to representations and warranties, indemnification and liability insurance, as may be customary or appropriate in combined primary and secondary offerings.

(b) Expenses. The Company will pay all Registration Expenses in connection with each registration of Registrable Securities requested pursuant to this Section 2.1.

(c) Priority in Piggyback Registrations. If a registration pursuant to this Section 2.1 involves an Underwritten Offering and the managing underwriter advises the Company in writing (a copy of which shall be provided to the Holders) that, in its opinion, the number of Registrable Securities and other Securities requested to be included in such registration exceeds the number which can be sold in such offering, so as to be likely to have a material and adverse effect on the price, timing or distribution of the Securities offered in such offering, then the Company will include in such registration: (i) first, the Securities the Company proposes to sell for its own account; and (ii) second, such number of Registrable Securities requested to be included in such registration which, in the opinion of such managing underwriter, can be sold without having the material and adverse effect referred to above, which number of Registrable Securities shall be allocated pro rata among the Registrable Securities held by all such requesting Holders on the basis of the relative number of Registrable Securities requested to be included in such registration by each such Holder (provided that any Securities thereby allocated to any such Holder that exceed such Holder’s request will be reallocated among the remaining requesting Holders in like manner).

(d) Excluded Transactions. The Company shall not be obligated to effect any registration of Registrable Securities under this Section 2.1 incidental to the registration of any of its Securities in connection with:

(i) a registration statement filed to cover issuances under employee benefits plans, dividend reinvestment plans, or a convertible debt offering; or

(ii) any registration statement relating solely to the acquisition or merger after the date hereof by the Company or any of its Subsidiaries of or with any other businesses.

(e) Plan of Distribution, Underwriters and Counsel. If a registration pursuant to this Section 2.1 involves an Underwritten Offering (other than any Marketed Underwritten Shelf Offering pursuant to Section 2.2(g)(ii)), the Company shall have the right to (i) determine the plan of distribution and (ii) select the investment banker or bankers and managers to administer the offering, including the lead managing underwriter.

(f) Shelf Takedowns. In connection with any shelf takedown (whether pursuant to Section 2.2(g) or at the initiative of the Company), the Holders may exercise “piggyback” rights in the manner described in this Agreement to have included in such takedown Registrable Securities held by them that are registered on such shelf registration statement.

6

Section 2.2 Registration Statements.

(a) The Company shall file with the SEC as soon as reasonably practicable following the Closing Date, and will use reasonable best efforts to cause to be declared effective by the SEC within sixty (60) days of the Closing Date, a shelf registration statement on Form ▇-▇, ▇▇▇▇ ▇-▇ or such other form under the Securities Act then available to the Company (the “Shelf Registration Statement”) providing for the resale by the Holders from time to time on a delayed or continuous basis pursuant to Rule 415 under the Securities Act of any or all of the Registrable Securities then held by the Holders (as determined by the Holders of a majority of the Registrable Securities).

(b) Subject to Section 2.2(c), the Company will use reasonable efforts to keep the Shelf Registration Statement continuously effective until the earlier of (i) three (3) years after the Shelf Registration Statement has been declared effective; (ii) the date on which all Registrable Securities covered by the Shelf Registration Statement have been sold thereunder, or otherwise cease to be Registrable Securities; and (iii) the date on which this agreement terminates pursuant to Section 4.1.

(c) Notwithstanding anything to the contrary contained in this Agreement, the Company shall be entitled, from time to time, by providing written notice to the Holders, to require the Holders to suspend sales of Registrable Securities under the Shelf Registration Statement during any Blackout Period. The Holders may recommence effecting sales of the Registrable Securities pursuant to the Shelf Registration Statement (or such filings) following further notice to such effect from the Company, which shall be given by the Company promptly following the expiration of any Blackout Period. After the expiration of any Blackout Period and without any further request from the Holders, the Company, to the extent necessary, 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.

(d) Expenses. The Company will pay all Registration Expenses in connection with each registration of Registrable Securities requested pursuant to this Section 2.2.

(e) Plan of Distribution, Underwriters and Counsel. If a requested registration pursuant to this Section 2.2 involves an Underwritten Offering, the Demand Party seeking registration of the Registrable Securities included in such Underwritten Offering shall have the right to (i) determine the plan of distribution and (ii) select the investment banker or bankers and managers to administer the offering, including the lead managing underwriter (provided that such investment banker or bankers and managers shall be reasonably satisfactory to the Company).

7

(f) Priority in Demand Registrations. If a requested registration pursuant to this Section 2.2 involves an Underwritten Offering and the managing underwriter advises the Company in writing (a copy of which shall be provided to the Holders) that, in its reasonable opinion, the number of Registrable Securities requested to be included in such registration (including Securities of the Company which are not Registrable Securities) exceeds the number which can be sold in such offering, so as to be likely to have a material and adverse effect on the price, timing or distribution of the Securities offered in such offering, then the number of such Registrable Securities to be included in such registration shall be allocated in the following order of priority: (i) first, up to the number of Registrable Securities requested to be included by a Demand Party in its Take-Down Notice and the other Holders, pro rata among all such holders on the basis of the number of Registrable Securities requested to be included therein by all such Holders, (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, pro rata on the basis of the amount of such other securities requested to be included or such other allocation method determined by the Company.

(g) Shelf Takedowns.

(i) Upon the written request of any Holder, at any time and from time to time, the Company will facilitate in the manner described in this Agreement a “takedown” of such Holder’s Registrable Securities off of an effective shelf registration statement (a “Shelf Take-Down”). Upon the written request of such Holder, the Company will file and seek the effectiveness of a post-effective amendment to an existing shelf registration statement in order to register up to the number of such Holder’s Registrable Securities previously taken down off of such shelf by such Holder and not yet “reloaded” onto such shelf registration statement.

(ii) At any time that a Shelf Registration Statement is effective, Blackstone (subject to a limit of two (2) times in any calendar year) and Summit (subject to a limit of one (1) time in any calendar year) (each of Blackstone and Summit, a “Demand Party”) may deliver a notice (a “Take-Down Notice”) to the Company that it intends to sell all or part of its Registrable Securities in an Underwritten Offering (including any Underwritten Offering where the plan of distribution set forth in the applicable Take-Down Notice includes a customary “road show” (including an “electronic road show”) or other substantial marketing effort by the Company and the underwriters (a “Marketed Underwritten Shelf Offering”)); provided, that a Demand Party may not deliver a Take-Down Notice prior to expiry of the Initial Lock-Up Period; provided, further, that Blackstone shall have the right to deliver the first Take-Down Notice provided that such Take-Down Notice is delivered by Blackstone within two-hundred and seventy (270) days of the Closing Date; provided, further, that a Demand Party may not deliver a Take-Down Notice for an Underwritten Offering or a Marketed Underwritten Shelf Offering unless the Registrable Securities requested to be sold in such offering have an aggregate offering price (based on the last reported sale price per share on the most recent trading day prior to such date on the principal securities exchange or market on which they are traded or, if the shares of Common Stock are no longer so traded, the fair value thereof (as determined in good faith by the Demand Party seeking registration of such Registrable Securities)) of at least (x) in the case of the first Take-Down Notice delivered by Summit, $25,000,000 and (y) for each other Take-Down Notice delivered by a Demand Party, $50,000,000.

8

If 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 2.3(f) to and including the date when each seller of Registrable Securities covered by such registration statement has received the copies of the supplemented or amended prospectus contemplated by Section 2.3(f).

(d) Each Holder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 2.3(l)(iv), it will forthwith discontinue disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until the lifting of such stop order, other order or suspension or the termination of such proceedings and, if so directed by the Company, each Holder will deliver to the Company or destroy (at the Company’s expense) all copies, other than permanent file copies then in its possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. If 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 2.3(l)(iv) to and including the date when such stop order, other order or suspension is lifted or such proceedings are terminated.

(e) In connection with any Underwritten Offering, the Holders of Registrable Securities agree to enter into customary “lock-up” agreements restricting the public sale or distribution of equity securities of the Company (including sales pursuant to Rule 144 under the Securities Act) to the extent required in writing by the lead managing underwriter(s) with respect to an applicable Underwritten Offering for a period of not more than ninety (90) days after the date of the “final” prospectus (or “final” prospectus supplement if the Underwritten Offering is made pursuant to a Shelf Registration Statement), pursuant to which such Underwritten Offering shall be made, plus, if applicable, an extension period, as may be proposed by the lead managing underwriter(s) to address FINRA regulations regarding the publishing of research, or such other period as is required by the lead managing underwriter(s); provided, however, such Holders shall not be subject to a lock-up period longer than the lock-up period to which the officers and directors of the Company are subject.

(f) In the event of any Marketed Underwritten Shelf Offering, the Company will not affect any public sale or distribution of any common equity (or securities convertible into or exchangeable or exercisable for common equity) for its own account, within sixty (60) days after the date of such Marketed Underwritten Shelf Offering except as may otherwise be agreed between the Company and the lead managing underwriter(s) of such Marketed Underwritten Shelf Offering.

13

(g) A Holder 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 (subject to the other terms and conditions of this Agreement). No such withdrawal shall affect the obligations of the Company with respect to the Registrable Securities not so withdrawn.

(h) With a view to making available the benefits of certain rules and regulations of the SEC which may at any time permit the sale of Securities of the Company to the public without registration after such time as a public market exists for Registrable Securities, the Company agrees:

(i) to 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 first registration under the Securities Act filed by the Company for an offering of its Securities to the public;

(ii) to use its commercially reasonable efforts to then 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 it is subject to such reporting requirements); and

(iii) so long as a Holder owns any Registrable Securities, to furnish to such Holder promptly upon request: (A) a written statement by the Company as to its compliance with the reporting requirements of Rule 144, and of the Securities Act and the Exchange Act (at any time it is subject to such reporting requirements); (B) a copy of the most recent annual or quarterly report of the Company; and (C) such other reports and documents of the Company as such Holder may reasonably request in availing itself or himself of any rule or regulation of the SEC allowing such Holder to sell any such Securities without registration.

(i) Counsel to represent Holders of Registrable Securities shall be selected by the Holders of at least a majority of the Registrable Securities included in the relevant registration.

ARTICLE III

INDEMNIFICATION

Section 3.1 Indemnification by the Company. If any registration of any Securities of the Company under the Securities Act pursuant to Section 2.1 or 2.2, the Company hereby indemnifies and agrees to hold harmless, to the fullest extent permitted by Law, each Holder who sells Registrable Securities covered by such registration statement, each Affiliate of such Holder and their respective directors and officers or general and limited partners (and the directors, officers, employees, Affiliates and controlling Persons of any of the foregoing), each other Person who participates as an underwriter in the offering or sale of such Securities and each other Person, if any, who controls such Holder or any such underwriter within the meaning of the Securities Act (each, and “Indemnified Party” and collectively, the “Indemnified Parties”), against any and all

14

losses, claims, damages or liabilities, joint or several, and reasonable and documented expenses to which such Indemnified Party may become subject under the Securities 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: (a) 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 preliminary, final or summary prospectus contained therein, or any amendment or supplement thereto, or any document incorporated by reference therein, or any other such disclosure document (including reports and other documents filed under the Exchange Act and any document incorporated by reference therein) or related document or report; (b) 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, in the case of a prospectus, in the light of the circumstances when they were made; or (c) any violation or alleged violation by the Company or any of its Subsidiaries of any federal, state, foreign or common law rule or regulation applicable to the Company or any of its Subsidiaries and relating to action or inaction in connection with any such registration, disclosure document or related document or report, 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 preliminary, final or summary prospectus, or any amendment 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 expressly 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 or any termination of this Agreement.

Section 3.2 Indemnification by the Holders and Underwriters. The Company may require, as a condition to including any Registrable Securities in any registration statement filed in accordance with Section 2.1 or 2.2, that the Company shall have received an undertaking reasonably satisfactory to it from the Holder of such Registrable Securities or any prospective underwriter to indemnify and hold harmless (in the same manner and to the same extent as set forth in Section 3.1) the Company, all other Holders or any prospective underwriter, as the case may be, and any of their respective Affiliates, directors, officers and controlling Persons, with respect to any untrue statement in or omission from such registration statement, any preliminary, final or summary prospectus contained therein, or any amendment or supplement, if such untrue statement or omission was made in reliance upon and in conformity with written information with respect to such Holder or underwriter furnished to the Company by such Holder or underwriter expressly for use in the preparation of such registration statement, preliminary, final or summary prospectus or amendment or supplement, or a document incorporated by reference into any of the foregoing. 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. In no event shall the liability of any selling Holder of Registrable Securities hereunder be greater in amount than the dollar amount of the proceeds actually received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation.

15

Section 3.3 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 Article III, 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 3.1 or 3.2, 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 selected by the Holders of at least a majority of the Registrable Securities included in the relevant registration, 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 without the prior written consent of the Indemnified Party (which consent will not be unreasonably withheld, conditioned, or delayed) unless (x) the sole relief provided is monetary damages and (y) such judgment or settlement includes 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 claim or litigation.

Section 3.4 Contribution. If the indemnification provided for hereunder from the indemnifying party is unavailable to an Indemnified Party hereunder in respect of any losses, claims, damages, liabilities or expenses referred to herein for reasons other than those described in the proviso in the first sentence of Section 3.1, then the indemnifying party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and Indemnified Parties in connection with the actions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of such indemnifying party and Indemnified Parties shall be determined by reference to, among other things, whether any 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 relates to information supplied by, such indemnifying party or Indemnified Parties, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action.

16

The amount paid or payable by a party under this Section 3.4 as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with any investigation or proceeding. In no event shall the liability of any selling Holder of Registrable Securities hereunder be greater in amount than the dollar amount of the proceeds actually received by such Holder upon the sale of the Registrable Securities giving rise to such contribution obligation.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 3.4 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. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

Section 3.5 Other Indemnification. Indemnification similar to that specified in this Article III (with appropriate modifications) shall be given by the Company and each seller of Registrable Securities with respect to any required registration or other qualification of Securities under any Law or with any Governmental Entity other than as required by the Securities Act.

Section 3.6 Non-Exclusivity. The obligations of the parties under this Article III will be in addition to any liability which any party may otherwise have to any other party.

ARTICLE IV

OTHER

Section 4.1 Term. This Agreement shall automatically terminate upon the earlier to occur of (a) such date and time as the Merger Agreement is terminated in accordance with its terms and (b) such date as no Registrable Securities remain outstanding. If this Agreement is terminated pursuant to this Section 4.1, this Agreement shall immediately then be terminated and of no further force and effect, except for the provisions set forth in this Article IV, which shall survive in accordance with their terms.

Section 4.2 Notices. Any notice, request, instruction or other document to be given hereunder by any party hereto to another party hereto shall be in writing and shall be deemed given (a) when delivered personally, (b) five (5) Business Days after being sent by certified or registered mail, postage prepaid, return receipt requested, (c) one (1) Business Day after being sent by Federal Express or other nationally recognized overnight courier, or (d) if transmitted by facsimile, if confirmed within 24 hours thereafter by a signed original sent in the manner provided in clause (a), (b) or (c) to parties at the following addresses (or at such other address for a party as shall be specified by prior written notice from such party):

No waiver by any party of any of the provisions hereof will be effective unless explicitly set forth in writing and executed by the party so waiving. Except as provided in the preceding sentence, no action taken pursuant to this Agreement, including without limitation, any investigation by or on behalf of any party, will be deemed to constitute a waiver by the party taking such action of compliance with any covenants or agreements contained herein. The waiver by any party hereto of a breach of any provision of this Agreement will not operate or be construed as a waiver of any subsequent breach.

Section 4.5 Third Parties.
