The Board of Directors of the Corporation (the “Board”) is hereby authorized to determine and alter all rights, preferences and privileges and qualifications, limitations and restrictions thereof (including, without limitation, voting rights and the limitation and exclusion thereof) granted to or imposed upon any wholly unissued series of Preferred Stock and the number of shares constituting any such series and the designation thereof, and to increase or decrease (but not below the number of shares of such series then outstanding) the number of shares of any series subsequent to the issue of shares of that series then outstanding. In the event that the number of shares of any series is so decreased, the shares constituting such reduction shall resume the status which such shares had prior to the adoption of the resolution originally fixing the number of shares of such series.

PART C. Powers, Preferences and Special Rights of Common Stock. Except as otherwise provided in this Part C or as otherwise required by applicable law, all shares of Class A-1 Common, Class A-2 Common and Class B Common shall be identical in all respects and shall entitle the holders thereof to the same rights, preferences and privileges, subject to the same qualifications, limitations and restrictions, as set forth herein.

Except as otherwise provided in this Part C or as otherwise required by applicable law, the holders of Class A-1 Common shall be entitled to one vote per share on all matters to be voted on by the stockholders of the Corporation, the holders of Class A-2 Common shall be entitled to three votes per share on all matters to be voted on by the stockholders of the Corporation, and the holders of Class B Common shall have no right to vote on any matters to be voted on by the stockholders of the Corporation.

Section 4. Restrictions on Transfer of Corporation Stock. Without the Board’s written consent, which it may withhold in its sole discretion, until the first anniversary of the date

hereof, none of the Other Stockholders or Solus Investor may Transfer any interest in any Corporation Stock, except pursuant to (i) a Public Sale, (ii) a Sale of the Company in accordance with Section 6 hereof, (iii) the repurchase provisions set forth in any agreement between the Corporation and an employee, officer, consultant or service provider of the Corporation or an Affiliate thereof, (iv) foreclosure proceedings by the Corporation with respect to shares of Corporation Stock pledged to the Corporation as collateral security, or (v) a Permitted Transfer. At any time on or after the first anniversary of the date hereof, each stockholder shall be permitted to Transfer any interest in any Corporation Stock, subject to Section 5 hereof and any applicable restrictions on transfer under the Securities Act and applicable state securities laws. In the case of, and as a condition to any Transfer by any Other Stockholder or Solus Investor (other than pursuant to Section 6 hereof or following an IPO), (1) the restrictions contained herein will continue to be applicable to such Corporation Stock after any such Transfer (unless the Corporation is the transferee), (2) the transferee(s) of such Corporation Stock is an “accredited investor” as defined under Rule 501 of Regulation D of the Securities Act (or any similar or equivalent provision then in force) and (3) neither the transferee(s) of such Corporation Stock nor any of its Affiliates may be a Competitor. Notwithstanding any other provision of this agreement, none of the Other Stockholders which is a legal entity (including a partnership, a corporation, a limited liability company, an association, a joint stock company, a trust, a joint venture or an unincorporated organization) that holds debt or equity securities of the Corporation as its primary asset shall authorize, permit or recognize the Transfer (directly or indirectly) of any of its equity interests, securities or other ownership interests without the prior written consent of the Board if such Transfer would violate this Section 4 if such Transfer was a Transfer of Corporation Stock.

Section 5. Rights of First Refusal. Pursuant to Section 202(c)(1) of the DGCL:

5A. After the first anniversary of the date hereof, if any Other Stockholder or Solus Investor enters into a binding agreement to Transfer any Corporation Stock (a “Sale Agreement”), such Other Stockholder and Solus Investor shall be entitled to Transfer such shares subject to the provisions of this Section 5. At least thirty (30) business days before any Transfer by any Other Stockholder or Solus Investor (a “Transferring Stockholder”) (other than a Permitted Transfer or in connection with a Public Sale or a Sale of the Company), of any Corporation Stock, such Transferring Stockholder shall deliver a written notice (the “Sale Notice”) to the Corporation and Carlyle Investor which shall include a copy of the Sale Agreement as well as a summary specifying in reasonable detail the identity of the prospective Transferee(s), the proposed number of each class of Corporation Stock to be Transferred (the “Transfer Stock”), and the proposed terms and conditions of the Transfer, including the proposed price per share for each class of Corporation Stock to be Transferred (the “Offered Terms and Conditions”); provided that in no event shall any Transfer of any Corporation Stock in accordance with this Section 5 by any Transferring Stockholder be made for any consideration other than cash payable upon consummation of such Transfer or in installments over time. No such Transfer shall be consummated unless each such prospective Transferee is reasonably acceptable to the Corporation and Carlyle Investor, and no such Transfer shall be consummated prior to the date on which the parties to the Transfer have been finally determined in accordance with this Section 5.

5B. The Corporation may elect to purchase any or all of the Transfer Stock at the same price and on the same terms and conditions specified in the Sale Notice by delivering written notice of such election to the Transferring Stockholder and Carlyle Investor as soon as practicable but in any event within twenty (20) business days after delivery to the Corporation and Carlyle Investor of the Sale Notice. If the Company does not elect within such twenty (20) business day period to purchase all of the Transfer Stock, then Carlyle Investor may elect to purchase, at the same price and on the same terms and conditions specified in the Sale Notice, any or all of the remaining Transfer Stock which the Company has not elected to purchase (the “Available Stock”) by delivering written notice of such election to the Transferring Stockholder as soon as practical but in any event within twenty-five (25) business days after delivery to the Corporation and Carlyle Investor of the Sale Notice (the “Election Period”).

5C. If the Corporation and/or Carlyle Investor have elected to purchase any or all of the Transfer Stock pursuant to this Section 5, such Transfer(s) shall be consummated as soon as practical after the delivery of the election notice(s) to the Transferring Stockholder, but in any event within thirty (30) business days after delivery to the Corporation and Carlyle Investor of the Sale Notice (the “ROFR Closing”). The Corporation and/or Carlyle Investor shall pay for the Transfer Stock to be purchased by delivery of a cashier’s or certified check or wire transfer of immediately available funds for the full amount of the purchase price at the ROFR Closing. At or prior to the consummation of such Transfer(s), the Transferring Stockholder must deliver to each such Person that exercised its rights to purchase Transfer Stock under this Section 5 (a “ROFR Person”), all certificates for the Corporation Stock being acquired by such ROFR Person (except, in the case of the Corporation for those certificates which are already in the custody of the Corporation), together with proper assignments in blank of the Corporation Stock with signatures properly guaranteed and with such other documents as may be required by such ROFR Person, as applicable, to provide reasonable assurance that each necessary endorsement is genuine and effective, and such ROFR Person shall be entitled to receive customary and reasonable written representations and warranties from the Transferring Stockholder regarding such sale of Corporation Stock (including representations and warranties regarding good title to such shares, free and clear of any liens or encumbrances).

5D. If the Corporation and/or Carlyle Investor, collectively, do not elect to purchase all of the Transfer Stock, the Transferring Stockholder may Transfer to the Transferee(s) identified in the Sale Notice all, but not less than all, of the remaining Transfer Stock, during the sixty (60) day period immediately following the expiration of the Election Period, for a purchase price no less than the price specified in the Sale Notice and on other terms no more favorable to the Transferee(s) thereof than specified in the Sale Notice.

5E. All costs and expenses of the Corporation incurred in connection with its compliance with this Section 5 shall be borne by the Transferring Stockholder.

Section 6. Sale of the Company. Pursuant to Section 202(c)(4) of the DGCL:

6A. Each stockholder of the Corporation hereby agrees that if at any time the holders of fifty percent (50%) or more of the voting power of the then outstanding shares of Class A Common (the “Approving Stockholders”) approve a Sale of the Company to a Person other than Carlyle Investor or its Affiliates (an “Approved Sale”), each stockholder of the

Corporation that is not an Approving Stockholder (the “Drag Along Stockholders”) shall vote for, consent to and raise no objections against such Approved Sale, and appoint Carlyle Investor or its designee as its representative to make all decisions in connection with any Approved Sale, regardless of the consideration being paid in such Approved Sale, so long as such Approved Sale complies with this Section 6. Without limiting the foregoing, but subject to the provisions of Section 6B, if the Approved Sale is structured (i) as a merger or consolidation, each such Drag Along Stockholder will waive any dissenters rights, appraisal rights or similar rights in conjunction with such merger or consolidation, (ii) as a sale of equity, each such Drag Along Stockholder will agree to sell all of such Drag Along Stockholder’s Corporation Stock on the terms and conditions approved by the Approving Stockholders, or (iii) as a sale of assets, each such Drag Along Stockholder will vote in favor of such Approved Sale and any subsequent liquidation or other distribution of the proceeds therefrom in accordance with the terms herein as approved by the Approving Stockholders. The Corporation and each stockholder will take all actions requested by the Approving Stockholders in connection with the consummation of an Approved Sale, including the execution of all ancillary documents in connection therewith requested by the Approving Stockholders; provided that it is acknowledged and agreed that the Other Stockholders that are also employees of the Corporation or any of its subsidiaries may be required, in connection with an Approved Sale, to enter into confidentiality, non competition, non solicitation and non hire provisions approved by the Board. For purposes hereof, a “Sale of the Company” means (i) any sale, transfer or issuance or series of sales, transfers and/or issuances of stock of the Corporation by the Corporation or any holders thereof (including, without limitation, any merger, consolidation or other transaction or series of related transactions having the same effect) which results in any Person or group of Persons (as the term “group” is used under the Securities Exchange Act of 1934), other than Carlyle Investor, owning stock of the Corporation possessing voting power to elect a majority of the Board or (ii) the sale or transfer of all or substantially all of the Corporation’s assets, determined on a consolidated basis; provided that the term “Sale of the Company” shall not include a Public Sale.

6B. Upon the consummation of the Approved Sale, each stockholder participating in such Approved Sale will receive the same portion of the aggregate consideration available to be distributed to the stockholders of the Corporation (in their capacity as such) that such stockholders participating in such sale (in their capacity as stockholders of the Corporation) would have received if such aggregate consideration had been distributed by the Corporation in accordance with the rights and preferences set forth herein as in effect immediately before such Approved Sale (and, in the event of a sale of Corporation Stock, assuming that the only securities of the Corporation outstanding were those Corporation Stock and other shares of capital stock involved in such Approved Sale); provided, that any convertible securities shall be deemed to be converted in the event that such conversion would yield greater proceeds herein; provided, further, that any consideration payable to any stockholder shall be reduced by the aggregate principal amount plus all accrued and unpaid interest on any indebtedness of any such stockholder to the Corporation or its subsidiaries. In the case of a stockholder who holds options or warrants exercisable into Corporation Stock which have not yet been exercised, the consideration received shall be deemed to be reduced (for purposes of such stockholder’s consideration only) by such option’s and/or warrant’s exercise price. To the extent any stockholder receives securities in lieu of cash or other consideration in the Approved Sale, such securities shall be deemed to be the same form of consideration so long as such securities are of a substantially equivalent value as the cash consideration received in such Approved Sale.

6C. Each Drag Along Stockholder will be obligated to make representations with respect to its own shares of capital stock and its own authority and ability to enter into the Approved Sale and other customary representations about such Drag Along Stockholder, and shall be required to provide indemnification in respect of, among other things, any representation made by the Corporation or its subsidiaries and/or an employee of the Corporation or its subsidiaries and/or made by any stockholder in respect of the Corporation, its subsidiaries or their respective businesses, operations, conditions, prospects or the like to the extent the Approving Stockholders similarly provide such indemnification. Each stockholder participating in such Approved Sale will be obligated to join on a pro rata basis (applied such that after giving effect thereto, the aggregate consideration paid to each stockholder would comply with the provisions of Section 6B above) in any purchase price adjustments, indemnification or other obligations that the sellers of Corporation Stock are required to provide in connection with an Approved Sale (other than any such obligations that relate solely to a particular stockholder, such as indemnification with respect to representations and warranties given by a stockholder regarding such stockholder’s title to and ownership of Corporation Stock, in respect of which only such stockholder will be liable); provided that, subject to Section 6D below and absent fraud, no stockholder shall be liable to the purchaser for any purchase price adjustments, indemnification or other obligations in excess of the aggregate gross proceeds (prior to reduction for indebtedness and other transaction expenses) received by the stockholders in connection with or pursuant to such Approved Sale (other than any such obligations that relate solely to a particular stockholder, such as indemnification with respect to representations and warranties given by a stockholder regarding such stockholder’s title to and ownership of Corporation Stock, in respect of which only such stockholder will be liable). Notwithstanding anything to the contrary contained herein, in the sole discretion of the Approving Stockholders, the proceeds with respect to an Approved Sale may be withheld from (and retained by the Approving Stockholders or their designee in trust for the benefit of) all sellers of such Corporation Stock in such aggregate amount as the Approving Stockholders deem necessary to cover any purchase price adjustments, indemnification or other obligations of the Corporation or such sellers of Corporation Stock; provided that such proceeds shall be withheld on the same basis among all such sellers.

6D. Notwithstanding anything to the contrary herein, if the Approving Stockholders agree to joint and several indemnification with respect to such Approved Sale, each Drag Along Stockholder shall agree to such joint and several indemnification as well, and in such event each Drag Along Stockholder shall enter into a contribution and indemnification or similar agreement acceptable to the Approving Stockholders pursuant to which each Drag Along Stockholder agrees to contribute amounts to and indemnify each other Drag Along Stockholder such that their liability will not exceed the aggregate amount of consideration received by such Drag Along Stockholder in connection with or pursuant to such Approved Sale (other than any such obligations that relate solely to a particular Drag Along Stockholder, such as indemnification with respect to representations and warranties given by a Drag Along Stockholder regarding such Drag Along Stockholder’s title to and ownership of Corporation Stock, and other than any obligations that relate to a particular Drag Along Stockholder’s fraud, in each case in respect of which only such Drag Along Stockholder will be liable).

6E. If the Corporation enters into a negotiation for an Approved Sale or an Approved Sale transaction for which Rule 506 (or any similar rule then in effect) promulgated by

the Securities and Exchange Commission may be available with respect to such negotiation or transaction (including a merger, consolidation or other reorganization), the Drag Along Stockholders will, at the request of the Board, appoint a purchaser representative (as such term is defined in Rule 501 or any similar rule), or such equivalent representative, reasonably acceptable to the Board. If any Drag Along Stockholder appoints a purchaser representative, or such equivalent representative, designated by the Board, the Corporation will, to the extent legally permitted, pay the fees of such purchaser representative, or such equivalent representative, but if any Drag Along Stockholder declines to appoint the purchaser representative, or such equivalent representative, designated by the Board such holder will appoint another purchaser representative, and such holder will be responsible for the fees of the purchaser representative, or such equivalent representative, so appointed.

6F. Each stockholder will bear its pro rata share (applied such that after giving effect thereto, the aggregate consideration paid to each holder of Corporation Stock would comply with the provisions of Section 6B) of the costs of any sale of such Corporation Stock pursuant to an Approved Sale to the extent such costs are incurred for the benefit of all stockholders participating in such Approved Sale and are not otherwise paid by the Corporation or the acquiring party. Costs incurred by stockholders on their own behalf will not be considered costs of the transaction hereunder; it being understood that the fees and disbursements of one counsel chosen by the Board will be deemed for the benefit of all stockholders participating in such Approved Sale.

6G. If any Drag Along Stockholder fails to deliver any certificates representing its shares of Corporation Stock, or in lieu thereof, a customary affidavit attesting to the loss or destruction of such certificate(s), such holder (i) will not be entitled to the consideration that such holder would otherwise receive in the Approved Sale until such holder cures such failure (provided that, after curing such failure, such holder will be so entitled to such consideration without interest), (ii) will be deemed, for all purposes, no longer to be a stockholder of the Corporation and will have no voting rights, (iii) will not be entitled to any dividends or other distributions declared after the Approved Sale with respect to the Corporation Stock held by such holder, (iv) will have no other rights or privileges granted to stockholders herein or any future agreement, and (v) in the event of liquidation of the Corporation, such holder’s rights with respect to any consideration that such holder would have received if such holder had complied with this Section 6, if any, will be subordinate to the rights of any equity holder.

Section 7. Holdback.

7A. In connection with an IPO, the holders of Corporation Stock shall enter into any holdback, lockup or similar agreement requested by the underwriters managing such IPO; provided, however, that no such holder shall be required to enter into an agreement that is more restrictive than that of any other holder.
