minimum vote shall be the required vote, in all matters other than the election of directors and certain non-binding advisory votes described below, the affirmative vote of a majority of the voting power of the outstanding shares present in person or represented by proxy at the meeting and entitled to vote on the matter shall be the act of the stockholders. In non-binding advisory matters with more than two possible vote choices, the affirmative vote of a plurality of the voting power of the outstanding shares present in person or represented by proxy at the meeting and entitled to vote on the matter shall be the recommendation of the stockholders.

SECTION 2.12 Treasury Stock . The Corporation shall not vote, directly or indirectly, shares of its own stock belonging to it or any other corporation, if a majority of shares entitled to vote in the election of directors of such corporation is held, directly or indirectly by the Corporation, and such shares will not be counted for quorum purposes;  provided, however,  that the foregoing shall not limit the right of the Corporation or such other corporation, to vote stock of the Corporation held in a fiduciary capacity.

Prompt notice of the taking of the corporate action without a meeting by less than unanimous written consent shall, to the extent required by law, be given to those stockholders who have not consented in writing and who, if the action had been taken at a meeting, would have been entitled to notice of the meeting if the record date for notice of such meeting had been the date that written consents signed by a sufficient number of holders to take the action were delivered to the Corporation.

(B) On and after the Trigger Date, subject to the rights of holders of any series of Preferred Stock with respect to such series of Preferred Stock, any action required or permitted to be taken by the stockholders of the Corporation must be taken at a duly held annual or special meeting of stockholders and may not be taken by any consent in writing in lieu of a meeting of such stockholders.

SECTION 7.6 Indemnification and Advancement of Expenses .

(A) The Corporation shall indemnify and hold harmless, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended, any person who was or is made a party or is threatened to be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (a “ proceeding ”) by reason of the fact that he, or a person for whom he is the legal representative, is or was a director or officer of the Corporation or, while a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, trustee, employee or agent of another corporation or of a partnership, joint venture, trust, other enterprise or nonprofit entity, including service with respect to an employee benefit plan (a “ Covered Person ”), whether the basis of such proceeding is alleged action in an official capacity as a director, officer, trustee, employee or agent, or in any other capacity while serving as a director, officer, trustee, employee or agent, against all expenses, liability and loss (including, without limitation, attorneys’ fees, judgments, fines, ERISA excise taxes and penalties and amounts paid in settlement) reasonably incurred or suffered by such Covered Person in connection with such proceeding.

20

(B) The Corporation shall, to the fullest extent not prohibited by applicable law as it presently exists or may hereafter be amended, pay the expenses (including attorneys’ fees) incurred by a Covered Person in defending any proceeding in advance of its final disposition;  provided ,  however , that to the extent required by applicable law, such payment of expenses in advance of the final disposition of the proceeding shall be made only upon receipt of an undertaking by the Covered Person to repay all amounts advanced if it should be ultimately determined by final judicial decision from which there is no further right to appeal (hereinafter, a “ final adjudication ”) that the Covered Person is not entitled to be indemnified under this  Section 7.6  or otherwise.

(C) The rights to indemnification and advancement of expenses under this  Section 7.6  shall be contract rights and such rights shall continue as to a Covered Person who has ceased to be a director, officer, trustee, employee or agent and shall inure to the benefit of his heirs, executors and administrators. Notwithstanding the foregoing provisions of this  Section 7.6 , except for proceedings to enforce rights to indemnification and advancement of expenses, the Corporation shall indemnify and advance expenses to a Covered Person in connection with a proceeding (or part thereof) initiated by such Covered Person only if such proceeding (or part thereof) was authorized by the Board.

(D) If a claim for indemnification under this  Section 7.6  (following the final disposition of such proceeding) is not paid in full within 60 days after the Corporation has received a claim therefor by the Covered Person, or if a claim for any advancement of expenses under this  Section 7.6  is not paid in full within 30 days after the Corporation has received a statement or statements requesting such amounts to be advanced, the Covered Person shall thereupon (but not before) be entitled to file suit to recover the unpaid amount of such claim. If successful in whole or in part, the Covered Person shall be entitled to be paid the expense of prosecuting such claim, or a claim brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, to the fullest extent permitted by applicable law. In any such action, the Corporation shall have the burden of proving that the Covered Person is not entitled to the requested indemnification or advancement of expenses under applicable law. In (1) any suit brought by a Covered Person to enforce a right to indemnification hereunder (but not in a suit brought by a Covered Person to enforce a right to an advancement of expenses) it shall be a defense that, and (2) in any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such expenses upon a final adjudication that, the Covered Person has not met any applicable standard for indemnification set forth in the DGCL. Neither the failure of the Corporation (including its directors who are not parties to such action, a committee of such directors, independent legal counsel or its stockholders) to have made a determination prior to the commencement of such suit that indemnification of the Covered Person is proper in the circumstances because the Covered Person has met the applicable standard of conduct set forth in the DGCL, nor an actual determination by the Corporation (including its directors who are not parties to such action, a committee of such directors, independent legal counsel or its stockholders) that the Covered Person has not met such applicable standard of conduct, shall create a presumption that the Covered Person has not met the applicable standard of conduct or, in the case of such a suit brought by the Covered Person, be a defense to such suit. In any suit brought by the Covered Person to enforce a right to indemnification or to an advancement of expenses hereunder, or brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the Covered Person is not entitled to be indemnified, or to such advancement of expenses, under this  Section 7.6  or otherwise shall be on the Corporation.

21

(E) The rights conferred on any Covered Person by this  Section 7.6  shall not be exclusive of any other rights that such Covered Person may have or hereafter acquire under any statute, any provision of the Certificate of Incorporation, these Bylaws, any agreement or vote of stockholders or disinterested directors or otherwise.

(F) This  Section 7.6  shall not limit the right of the Corporation, to the extent and in the manner permitted by applicable law, to indemnify and to advance expenses to persons other than Covered Persons when and as authorized by appropriate corporate action.

(G) Any Covered Person entitled to indemnification and/or advancement of expenses, in each case pursuant to this  Section 7.6 , may have certain rights to indemnification, advancement and/or insurance provided by one or more persons with whom or which such Covered Person may be associated (including, without limitation, the Sponsor). The Corporation hereby acknowledges and agrees that (1) the Corporation shall be the indemnitor of first resort with respect to any proceeding, expense, liability or matter that is the subject of this  Section 7.6 , (2) the Corporation shall be primarily liable for all such obligations and any indemnification afforded to a Covered Person in respect of a proceeding, expense, liability or matter that is the subject of this  Section 7.6 , whether created by law, organizational or constituent documents, contract or otherwise, (3) any obligation of any persons with whom or which a Covered Person may be associated (including, without limitation, the Sponsor) to indemnify such Covered Person and/or advance expenses or liabilities to such Covered Person in respect of any proceeding shall be secondary to the obligations of the Corporation hereunder, (4) the Corporation shall be required to indemnify each Covered Person and advance expenses to each Covered Person hereunder to the fullest extent provided herein without regard to any rights such Covered Person may have against any other person with whom or which such Covered Person may be associated (including, without limitation, the Sponsor) or insurer of any such person, and (5) the Corporation irrevocably waives, relinquishes and releases any other person with whom or which a Covered Person may be associated (including, without limitation, the Sponsor) from any claim of contribution, subrogation or any other recovery of any kind in respect of amounts paid by the Corporation hereunder.

(H) The Corporation may maintain insurance, at its expense, to protect itself and any person who is or was serving as a director, officer, employee or agent of the Corporation or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the DGCL.

SECTION 7.7 Facsimile and Electronic Signatures . In addition to the provisions for use of facsimile or electronic signatures elsewhere specifically authorized in these Bylaws, facsimile or electronic signatures of any officer or officers of the Corporation may be used.

SECTION 7.8 Reliance Upon Books, Reports and Records . Each director, each member of any committee designated by the Board and each officer of the Corporation shall, in the performance of his duties, be fully protected in relying in good faith upon the records of the

22

Corporation and upon information, opinions, reports or statements presented to the Corporation by any of the Corporation’s officers or employees, or committees designated by the Board, or by any other person as to the matters the member reasonably believes are within such other person’s professional or expert competence and who has been selected with reasonable care by or on behalf of the Corporation.

ARTICLE VIII

AMENDMENTS

SECTION 8.1 Amendments . In furtherance of, and not in limitation of, the powers conferred by the laws of the State of Delaware, the Board is expressly authorized to adopt, amend or repeal the Bylaws of the Corporation;  provided, however , that where an amendment to the Bylaws of the Corporation is to be acted upon at a special meeting of directors, notice of such amendment, alteration or repeal is contained in the notice or waiver of notice of such special meeting. Any adoption, amendment or repeal of the Bylaws of the Corporation by the Board shall require the approval of a majority of the Whole Board. Stockholders shall also have the power to adopt, amend or repeal the Bylaws of the Corporation;  provided ,  however , that, in addition to any vote of the holders of any class or series of stock of the Corporation required by law or by the Certificate of Incorporation, the Bylaws of the Corporation may be adopted, altered, amended or repealed by the stockholders of the Corporation only (A) prior to the Trigger Date, by the affirmative vote of holders of not less than 50% in voting power of the outstanding shares of stock entitled to vote thereon, voting together as a single class, or (B) on and after the Trigger Date by the affirmative vote of holders of not less than 66 2/3% in voting power of the outstanding shares of stock entitled to vote thereon, voting together as a single class. No Bylaws hereafter made or adopted, nor any repeal of or amendment thereto, shall invalidate any prior act of the Board that was valid at the time it was taken. So long as the Stockholders’ Agreement remains in effect, the Board shall not approve any amendment, alteration or repeal of any provision of these Bylaws, or the adoption of any new Bylaw, that would be contrary to or inconsistent with the then-applicable terms of the Stockholders’ Agreement.

Notwithstanding the foregoing, (1) no amendment to the Stockholders’ Agreement (whether or not such amendment modifies any provision of the Stockholders’ Agreement to which these Bylaws are subject) shall be deemed an amendment of these Bylaws for purposes of this  Section 8.1 , and (2) no amendment, alteration or repeal of Section  7.6  shall adversely affect any right or protection existing under these Bylaws immediately prior to such amendment, alteration or repeal, including any right or protection of a present or former director, officer or employee thereunder in respect of any act or omission occurring prior to the time of such amendment.

15

therein, in the light of the circumstances under which they were made, not misleading; provided , however , that the Company shall not be liable to any Holder Indemnified Person to the extent that any such claim arises out of, is based upon or results from an untrue or alleged untrue statement or omission or alleged omission made in such Registration Statement, such preliminary, summary or final Prospectus or free writing Prospectus or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Holder Indemnified Person specifically for use in the preparation thereof. The Company shall notify the Holders promptly of the institution, threat or assertion of any Proceeding of which the Company is aware in connection with the transactions contemplated by this Agreement. This indemnity shall be in addition to any liability the Company may otherwise have and shall remain in full force and effect regardless of any investigation made by or on behalf of such Holder Indemnified Person or any indemnified party and shall survive the transfer of such securities by such Holder. Notwithstanding anything to the contrary herein, this Section  6 shall survive any termination or expiration of this Agreement indefinitely.

(b) In connection with any Registration Statement in which a Holder participates, such Holder shall, severally and not jointly, indemnify and hold harmless the Company, its Affiliates and each of their respective officers, directors and any agent thereof, to the fullest extent permitted by applicable law, from and against any and all Losses as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in any such Registration Statement, or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein not misleading, or in any preliminary Prospectus (if used prior to the Effective Date of such Registration Statement), any summary or final Prospectus or free writing Prospectus or in any amendment or supplement thereto (if used during the period the Company is required to keep the Registration Statement current), or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading, but only to the extent that the same are made in reliance and in conformity with information relating to the Holder furnished in writing to the Company by such Holder for use therein. This indemnity shall be in addition to any liability such Holder may otherwise have and shall remain in full force and effect regardless of any investigation made by or on behalf of the Company or any indemnified party. In no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the proceeds received by such Holder from the sale of the Registrable Securities giving rise to such indemnification obligation.

(c) Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim or there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld). An indemnifying party that is not entitled to, or elects not to, assume the

16

defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel (in addition to any local counsel) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party there may be one or more legal or equitable defenses available to such indemnified party that are in addition to or may conflict with those available to another indemnified party with respect to such claim. Failure to give prompt written notice shall not release the indemnifying party from its obligations hereunder.

(d) If the indemnification provided for in this Section  6 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any Losses referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and of the indemnified party, on the other, in connection with the untrue or alleged untrue statement of a material fact or the omission to state a material fact that resulted in such Losses, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided , that in no event shall any contribution by a Holder hereunder exceed the net proceeds from the offering received by such Holder.

7. Facilitation of Sales Pursuant to Rule 144 . To the extent it shall be required to do so under the Exchange Act, the Company shall timely file the reports required to be filed by it under the Exchange Act or the Securities Act (including the reports under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144), and shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable the Holders to sell Registrable Securities without registration under the Securities Act within the limitations of the exemption provided by Rule 144. Upon the request of any Holder in connection with that Holder’s sale pursuant to Rule 144, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements.

8. Miscellaneous .

(a) Remedies . In the event of actual or potential breach by the Company of any of its obligations under this Agreement, each Holder, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. The Company agrees that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it of any of the provisions of this Agreement and further agrees that, in the event of any action for specific performance in respect of such breach, it shall waive the defense that a remedy at law would be adequate.

17

(b) Discontinued Disposition . Subject to the last sentence of Section  3(o) , each Holder agrees that, upon receipt of a notice from the Company of the occurrence of any event of the kind described in clauses (ii) through (v) of Section  3(e) , such Holder will forthwith discontinue disposition of such Registrable Securities under the Registration Statement until such Holder’s receipt of the copies of the supplemental Prospectus or amended Registration Statement as contemplated by Section  3(j) or until it is advised in writing by the Company that the use of the applicable Prospectus may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement (a “ Suspension Period ”). The Company may provide appropriate stop orders to enforce the provisions of this Section  8(b) .

(c) Amendments and Waivers . No provision of this Agreement may be waived or amended except in a written instrument signed by the Company and Holders that hold a majority of the Registrable Securities as of the date of such waiver or amendment; provided , that any waiver or amendment that would have a disproportionate adverse effect on a Holder relative to the other Holders shall require the consent of such Holder. The Company shall provide prior notice to all Holders of any proposed waiver or amendment. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any Party to exercise any right hereunder in any manner impair the exercise of any such right.

(d) Notices . Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile or electronic mail as specified in this Section  8(d) prior to 5:00 p.m. Eastern Time on a Business Day, (ii) the Business Day after the date of transmission, if such notice or communication is delivered via facsimile or electronic mail as specified in this Agreement later than 5:00 p.m. Eastern Time on any date and earlier than 11:59 p.m. Eastern Time on such date, (iii) the Business Day following the date of mailing, if sent by nationally recognized overnight courier service (iv) upon actual receipt by the Party to whom such notice is required to be given.

Except as provided in this Section  8(e) , this Agreement, and any rights or obligations hereunder, may not be assigned without the prior written consent of the Company (acting through the Board of Directors) and the Holders. Notwithstanding anything in the foregoing to the contrary, the rights of a Holder pursuant to this Agreement with respect to all or any portion of its Registrable Securities may be assigned without such consent (but only with all related obligations) with respect to such Registrable Securities (and any Registrable Securities issued as a dividend or other distribution with respect to, in exchange for or in replacement of such Registrable Securities) by such Holder to a transferee of such Registrable Securities; provided , that (i) the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the Registrable Securities with respect to which such registration rights are being assigned and (ii) such transferee or assignee agrees in writing to be bound by and subject to the terms set forth in this Agreement. The Company may not assign its rights or obligations hereunder without the prior written consent of the Holders.

(f) No Third Party Beneficiaries . Nothing in this Agreement, whether express or implied, shall be construed to give any Person, other than the parties hereto or their respective successors and permitted assigns, any legal or equitable right, remedy, claim or benefit under or in respect of this Agreement.

This Agreement may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same Agreement. In the event that any signature is delivered by facsimile or electronic mail transmission, such signature shall create a valid binding obligation of the Party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such signature delivered by facsimile or electronic mail transmission were the original thereof.

(h) Governing Law; Consent to Jurisdiction; Waiver of Jury Trial . This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of Delaware.

Service of process in connection with any such suit, action or proceeding may be served on each Party anywhere in the world by the same methods as are specified for the giving of notices under this Agreement. Each of the Parties irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE PARTIES HEREBY WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.

GOVERNANCE MATTERS

Section 2.1 Designees .

(a) Upon the closing of the IPO, the Board shall consist of 8 directors, including Charles E. Price, Dorsey “Ron” McCall, Mark Spender, Stephen Tritch, Brian Ferraioli and Claire Babineaux-Fontenot. The Board will be divided into three classes of directors, with each class as equal in number as possible, serving staggered three-year terms as set forth in the Certificate of Incorporation, and such directors will be removable only for “cause” as set forth in the Certificate of Incorporation.

(b) Following the closing of the IPO, BCP shall have the right, but not the obligation, to nominate to the Board a number of designees equal to at least: (i) a majority of the Total Number of Directors, so long as BCP Beneficially Owns 50% or more of the outstanding shares of Common Stock; (ii) 40% of the Total Number of Directors, in the event that BCP Beneficially Owns 40% or more, but less than 50%, of the outstanding shares of Common Stock; (iii) 30% of the Total Number of Directors, in the event that BCP Beneficially Owns 30% or more, but less than 40%, of the outstanding shares of Common Stock; (iv) 20% of the Total Number of Directors, in the event that BCP Beneficially Owns 20% or more, but less than 30%, of the outstanding shares of Common Stock; and (v) 10% of the Total Number of Directors, in the event that BCP Beneficially Owns 5% or more, but less than 20%, of the outstanding shares of Common Stock. If BCP Beneficially Owns less than 5% of the outstanding shares of Common Stock, it shall not be entitled to designate a nominee. For purposes of calculating the number of directors that BCP is entitled to designate pursuant to the immediately preceding sentence, any fractional amounts shall automatically be rounded up to the nearest whole number (e.g., one and one quarter (1 ^1/4 ) directors shall equate to two (2) directors), and any such calculations shall be made after taking into account any increase in the Total Number of Directors.

3

(c) In the event that BCP has nominated less than the total number of designees BCP shall be entitled to nominate pursuant to Section  2.1(b) , BCP shall have the right, at any time, to nominate such additional designees to which it is entitled, in which case the Company and the directors shall take all Necessary Action, to the fullest extent permitted by applicable Law (including with respect to fiduciary duties under Delaware law), to (x) enable BCP to nominate and effect the election or appointment of such additional individuals, whether by increasing the size of the Board or otherwise, and (y) designate such additional individuals nominated by BCP to fill such newly-created vacancies or to fill any other existing vacancies. Each such individual whom BCP shall actually nominate pursuant to this Section  2.1 and who is thereafter elected to the Board to serve as a director shall be referred to herein as a “ BCP Director . ”

(d) CEP Holdings shall have the right, but not the obligation, to nominate Charles E. Price to the Board for so long as CEP Holdings Beneficially Owns at least 10% or more of the outstanding shares of Common Stock or Charles E. Price holds the title of Chief Executive Officer of the Company.

For the avoidance of doubt, the rights granted to BCP to designate members of the Board are additive to, and not intended to limit in any way, the rights that BCP or its Affiliates may have to nominate, elect or remove directors under the Company’s Certificate of Incorporation, Bylaws or the General Corporation Law of the State of Delaware.

The Company agrees, to the fullest extent permitted by applicable law (including with respect to any applicable fiduciary duties under Delaware law), to take all Necessary Action to effectuate the above by; (A) including the persons designated pursuant to this Section  2.1 in the slate of nominees recommended by the Board for election at any meeting of stockholders called for the purpose of electing directors, (B) nominating and recommending each such individual to be elected as a director as provided herein, (C) soliciting proxies or consents in favor thereof, and (D) without limiting the foregoing, otherwise using its reasonable best efforts to cause such nominees to be elected to the Board, including providing at least as high a level of support for the election of such nominees as it provides to any other individual standing for election as a director. The Company is entitled to identify such individual(s) nominated pursuant to Section  2.1(b) as a BCP Director pursuant to this Agreement.

(e) At any time the members of the Board are allocated among separate classes of directors, to the fullest extent permitted by law, (i) the BCP Directors shall be in different classes of directors to the extent practicable and (ii) the Company shall consult with BCP regarding the class or classes of directors to which the BCP Directors shall be designated and the Company and the Principal Stockholders shall take all Necessary Action, including using their reasonable best efforts, to cause the BCP Directors to be designated to the class or classes requested by BCP.

4

(f) So long as BCP is entitled to designate one or more nominees pursuant to Section  2.1(b) , BCP shall have the right to request the removal of any BCP Director (with or without cause) nominated by BCP, from time to time and at any time, from the Board, exercisable upon written notice to the Company, and the Company and the Principal Stockholders shall take all Necessary Action to cause such removal.

(g) So long as BCP Beneficially Owns at least 10% of the outstanding shares of Common Stock, the Company shall take all Necessary Action to cause any committee of the Board to include in its membership at least one BCP Director, except to the extent that such membership would violate applicable securities laws or stock exchange or stock market rules.

(h) Nothing in this Section  2.1 shall be deemed to require that any party hereto, or any Affiliate thereof, act or be in violation of any applicable provision of law, regulation, legal duty or requirement or stock exchange or stock market rule.

(i) In the event that a vacancy is created on the Board at any time by the death, disability, resignation or removal (whether by BCP or otherwise in accordance with the Company’s Certificate of Incorporation and Bylaws, as either may be amended or restated from time to time) of a BCP Director, BCP shall be entitled to designate an individual to fill the vacancy so long as the total number of persons that will serve on the Board as BCP Directors immediately following the filling of such vacancy will not exceed the total number of persons BCP is entitled to designate pursuant to Section  2.1(b) on the date of such replacement designation. The Company and the Principal Stockholders shall take all Necessary Action to cause such replacement BCP Director to become a member of the Board.

(j) In the event that the number of nominees that BCP is entitled to designate pursuant to Section  2.1(a) decreases below the number of BCP Directors then on the Board, to the extent requested by the nominating and corporate governance committee, BCP shall promptly cause a number of BCP Directors to resign from service on the Board (and all committees thereof on which such BCP Director serves) so that the number of BCP Directors is no greater than the number of nominees BCP is entitled to designate pursuant to Section  2.1(b) , and promptly thereafter the Company shall take all Necessary Action to cause the Board to cause the size of the Board to decrease by such number and to remove such BCP Director from office.

Section 2.2 Restrictions on Other Agreements . No Principal Stockholder shall, directly or indirectly, grant any proxy or enter into or agree to be bound by any voting trust, agreement or arrangement of any kind with respect to its shares of Common Stock if and to the extent the terms thereof conflict with the provisions of this Agreement (whether or not such proxy, voting trust, agreement or agreements are with other Principal Stockholders, holders of shares of Common Stock that are not parties to this Agreement or otherwise).

5

Section 2.3 Lock-Up.

(a) Each of the Management Members party hereto hereby agrees that, without the prior written consent of the Company and BCP, it will not, during the period ending 365 days after the date this agreement becomes effective (such period, subject to Section  2.3(c) below, the “ Restricted Period ”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended), or any other securities so owned convertible into or exercisable or exchangeable for Common Stock or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise.

(b) The restrictions contained in Section  2.3(a) shall not apply to (i) transfers of shares of Common Stock or any security convertible into Common Stock as a bona fide gift or (ii) distributions or transfers of shares of Common Stock or any security convertible into Common Stock to any of its Affiliates; provided that in the case of any transfer or distribution pursuant to this Section  2.3(b) , each donee or distributee shall enter into a written agreement containing substantially identical restrictions to those set forth in the preceding paragraph and this paragraph.

(c) The Company and BCP hereby agree to notify the Management Members if either the Company or BCP intends to take the position on any tax return, or in any federal, state, or local audits, examinations, investigations, or other administrative or court proceedings with respect to income taxes that the pre-IPO contributions to the Company by BCP and the other Principal Stockholders did not qualify under Section 351(a) of the Internal Revenue Code of 1986, as amended (the “ Code ”). Notwithstanding anything herein to the contrary, if (i) the Company or BCP notifies the Management Members in accordance with the immediately preceding sentence that the Company or BCP intends to take the position that the pre-IPO transactions did not qualify under Section 351(a) of the Code or (ii) in the reasonable opinion of tax advisors to the Company or the Management Members, the pre-IPO contributions to the Company by BCP and the other Principal Stockholders did not qualify under Section 351(a) of the Code, then the Restricted Period set forth in Section  2.3(a) above shall be the period ending 180 days after the date of this agreement.
