Section 2.2 NOL Schedule.

10

Section 2.3 Tax Benefit Schedule.

(a) Tax Benefit Schedule. Within ninety (90) calendar days after the extended due date of the U.S. federal Corporation Return for any Taxable Year in which there is a Realized Tax Benefit or Realized Tax Detriment, the Corporation shall provide to the Agent: (i) a schedule showing, in reasonable detail, (A) the calculation of the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year, (B) the portion of the Net Tax Benefit, if any, that is allocable to each TRA Holder, (C) the Accrued Amount with respect to any such Net Tax Benefit that is allocable to such TRA Holder, (D) the Tax Benefit Payment determined pursuant to Section 3.1(b) due to each such TRA Holder, and (E) the portion of such Tax Benefit Payment that the Corporation intends to treat as Imputed Interest (a “Tax Benefit Schedule”), (ii) a reasonably detailed calculation by the Corporation of the Hypothetical Tax Liability (the “without” calculation), (iii) a reasonably detailed calculation by the Corporation of the Actual Tax Liability (the “with” calculation), (iv) a copy of the Corporation Return for such Taxable Year, (v) a Corporation Letter supporting such Tax Benefit Schedule and (vi) any other work papers reasonably requested by the Agent. In addition, the Corporation shall allow the Agent reasonable access at no cost to the appropriate representatives of the Corporation in connection with a review of such Tax Benefit Schedule. The Tax Benefit Schedule will become final as provided in Section 2.4(a) and may be amended as provided in Section 2.4(b) (subject to the procedures set forth in Section 2.4(b)).

(b) Applicable Principles. The Realized Tax Benefit or Realized Tax Detriment for each Taxable Year is intended to measure the decrease or increase in the Corporation’s actual liability for Taxes for such Taxable Year that is attributable to the Basis Adjustments, the Blocker NOLs, the Closing Date Basis, and Imputed Interest, determined using a “with and without” methodology. For the avoidance of doubt, (i) such actual liability for Taxes will take into account the deduction of the portion of the Tax Benefit Payment that must be accounted for as interest under the Code based upon the characterization of Tax Benefit Payments as additional consideration payable by the Corporation, and (ii) in addition to using the Assumed State and Local Tax Rate for purposes of determining the state and local Hypothetical Tax Liability, the Corporation may use reasonable estimation methodologies for calculating the portion of any Realized Tax Benefit or Realized Tax Detriment attributable to U.S. state or local Taxes. For purposes of calculating the Realized Tax Benefit or Realized Tax Detriment for any Taxable Year, carryforwards or carrybacks of any Tax item (such as a net operating loss) attributable to the Basis Adjustments, the Blocker NOLs, the Closing Date Basis, and Imputed Interest shall be considered to be subject to the rules of the Code and the Treasury Regulations and the corresponding provisions of state and local Tax laws, as applicable, governing the use, limitation, and expiration of carryforwards or carrybacks of the relevant type. If a carryforward or carryback of any Tax item includes a portion that is attributable to the Basis Adjustment, the Blocker NOLs, the Closing Date Basis, or Imputed Interest (a “TRA Portion”) and another portion that is not so attributable (a “Non-TRA Portion”), such respective portions shall be considered to be used in accordance with the “with and without” methodology so that: (i) the amount of any Non-TRA Portion is deemed utilized first, followed by the amount of any TRA Portion; and (ii) in the case of a carryback of a Non-TRA Portion, such carryback shall not affect the original “with and without” calculation made in the applicable prior Taxable Year. For the avoidance of doubt, the TRA Portion of any Tax item when such item is incurred shall be determined using a marginal “with and without” methodology by calculating (i) the amount of such Tax item for all Tax purposes taking into account the Basis Adjustments, the Closing Date Basis, the Blocker NOLs and Imputed Interest and (ii) the amount of such Tax item for all Tax purposes without taking into account the Basis Adjustments, the

11

Closing Date Basis, the Blocker NOLs or Imputed Interest, with the TRA Portion equal to the excess of the amount specified in clause (i) over the amount specified in clause (ii) (but only if such excess is greater than zero). The parties agree that (i) any payment under this Agreement to MLSH 1 (or its successors or assigns), including the Accrued Amount (other than amounts accounted for as Imputed Interest) will be treated as a subsequent upward adjustment to the purchase price of the relevant Exchangeable Units and will have the effect of creating additional Basis Adjustments to Reference Assets for the Corporation in the year of payment, and (ii) as a result, such additional Basis Adjustments will be incorporated into the calculation for the year of payment and into future year calculations, as appropriate.

Section 2.4 Procedure: Amendments.

(a) An applicable Schedule or amendment thereto shall become final and binding on all parties thirty (30) calendar days from the first date on which the Agent has received the applicable Schedule or amendment thereto unless (i) the Agent, within thirty (30) calendar days after receiving an applicable Schedule or amendment thereto, provides the Corporation with notice of a material objection to such Schedule (“Objection Notice”) made in good faith or (ii) the Agent provides a written waiver of such right of any Objection Notice within the period described in clause (i) above, in which case such Schedule or amendment thereto becomes binding on the date a waiver from the Agent has been received by the Corporation. If the Corporation and Agent, for any reason, are unable to successfully resolve the issues raised in an Objection Notice within thirty (30) calendar days after receipt by the Corporation of such Objection Notice, the Corporation and Agent shall employ the Reconciliation Procedures under Section 7.9.

(b) The applicable Schedule for any Taxable Year may be amended from time to time by the Corporation (i) in connection with a Determination affecting such Schedule, (ii) to correct inaccuracies in the Schedule identified as a result of the receipt of additional factual information relating to a Taxable Year after the date the Schedule was provided to the Agent, (iii) to comply with the Expert’s determination under the Reconciliation Procedures, (iv) to reflect a change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable to a carryback or carryforward of a loss or other Tax item to such Taxable Year, (v) to reflect a change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable to an amended Corporation Return filed for such Taxable Year or (vi) to adjust an Exchange Schedule to take into account payments made pursuant to this Agreement (any such Schedule, an “Amended Schedule”). Unless otherwise agreed to in writing by the Agent, the Corporation shall provide an Amended Schedule to the Agent (A) within sixty (60) calendar days of the occurrence of an event referenced in clauses (i) through (v) of the preceding sentence and (B) in connection with the delivery of the Tax Benefit Schedule for the year of the applicable payment in the event of an adjustment pursuant to clause (vi) of the preceding sentence. For the avoidance of doubt, in the event a Schedule is amended after such Schedule becomes final pursuant to Section 2.4(a), the Amended Schedule shall not be taken into account in calculating any Tax Benefit Payment in the Taxable Year to which the amendment relates but instead shall be taken into account in calculating the Cumulative Net Realized Tax Benefit for the Taxable Year in which the amendment actually occurs.

ARTICLE III

TAX BENEFIT PAYMENTS

Section 3.1 Payments.

(a) Within five (5) calendar days after a Tax Benefit Schedule delivered to the Agent becomes final in accordance with Section 2.4(a), the Corporation shall pay to each TRA Holder the Tax Benefit Payment for such Taxable Year in the percentages set forth on Schedule A, which such schedule may be updated by the Corporation with the written consent of the Agent after the day hereof. Each such payment shall be made by check, by wire transfer of immediately available funds to the bank account previously designated by the TRA Holder to the Corporation, or as otherwise agreed by the Corporation and the TRA Holder. For the avoidance of doubt, no Tax Benefit Payment shall be made in respect of estimated Tax payments, including, without limitation, U.S. federal or state estimated income Tax payments.

(b) A “Tax Benefit Payment” for a Taxable Year means an amount, not less than zero, equal to the sum of the Net Tax Benefit and the Accrued Amount with respect thereto for such Taxable Year. Subject to Section 3.3 the “Net Tax Benefit” for a Taxable Year shall be an amount equal to the excess, if any, of (i) 85% of the Cumulative Net Realized Tax Benefit as of the end of such Taxable Year over (ii) the total amount of payments previously made under this Section 3.1 (excluding payments attributable to Accrued Amounts); provided, for the avoidance of doubt, that no TRA Holder shall be required to return any portion of any previously made Tax Benefit Payment. The “Accrued Amount” with respect to any portion of a Net Tax Benefit shall equal an amount determined in the same manner as interest on such portion of the Net Tax Benefit for a Taxable Year calculated at the Agreed Rate from the due date (without extensions) for filing the Corporation Return for such Taxable Year until the Payment Date. For the avoidance of doubt, for Tax purposes, the Accrued Amount shall not be treated as interest but shall instead be treated as additional consideration for the acquisition of Exchangeable Units in an Exchange or the stock of the Blockers in the Reorganization Transactions (as applicable) unless otherwise required by law. Notwithstanding anything herein to the contrary, unless otherwise specified by a TRA Holder in the Exchange Notice for any Exchange, the aggregate Tax Benefit Payments attributable to any Closing Date Basis and Basis Adjustments in respect of such Exchange (other than amounts accounted for as interest under the Code) shall not exceed 40% of the fair market value of the consideration received on such Exchange.

Section 3.2    No Duplicative Payments. It is intended that the provisions of this Agreement will not result in duplicative payment of any amount (including interest) required under this Agreement. It is also intended that the provisions of this Agreement will result in 85% of the Cumulative Net Realized Tax Benefit, and the Accrued Amount thereon, being paid to the TRA Holders. The provisions of this Agreement shall be construed in the appropriate manner to achieve these fundamental results.

Section 3.3    Coordination of Benefits.

(a) If for any reason the Corporation does not fully satisfy its payment obligations to make all Tax Benefit Payments due under this Agreement in respect of a particular Taxable Year, then (i) the Corporation will pay the same proportion of each Tax Benefit Payment due to each TRA Holder in respect of such Taxable Year, without favoring one obligation over the other, and (ii) no Tax Benefit Payment shall be made in respect of any Taxable Year until all Tax Benefit Payments in respect of prior Taxable Years have been made in full.

13

(b) To the extent the Corporation makes a payment to a TRA Holder in respect of a particular Taxable Year under Section 3.1(a) (taking into account Section 3.3(a) and (b), but excluding payments attributable to Accrued Amounts) in an amount in excess of the amount of such payment that should have been made to such TRA Holder in respect of such Taxable Year, then (i) such TRA Holder shall not receive further payments under Section 3.1(a) until such TRA Holder has foregone an amount of payments equal to such excess and (ii) the Corporation will pay the amount of such TRA Holder’s foregone payments to the other Persons to whom a payment is due under this Agreement in a manner such that each such Person to whom a payment is due under this Agreement, to the maximum extent possible, receives aggregate payments under Section 3.1(a) (taking into account Section 3.3(a) and this Section 3.3(b), but excluding payments attributable to Accrued Amounts) in the amount it would have received if there had been no excess payment to such TRA Holder.

ARTICLE IV

TERMINATION

Section 4.1 Early Termination by the Corporation. With the written approval of a majority of its independent directors, the Corporation may terminate this Agreement at any time by paying to each TRA Holder the Early Termination Payment due to such TRA Holder pursuant to
Section 4.5(b), provided, however, that this Agreement shall only terminate upon the receipt of the Early Termination Payment by the TRA Holders (such termination, an “Early Termination”). Upon payment of the Early Termination Payment by the Corporation, the Corporation shall not have any further payment obligations under this Agreement, other than for any (i) Tax Benefit Payment previously due and payable but unpaid as of the Early Termination Notice and (ii) any Tax Benefit Payment due for any Taxable Year ending prior to, with or including the Early Termination Date (except to the extent that the amount described in clause (ii) is included in the Early Termination Payment).

Section 4.2 Early Termination upon Change of Control. In the event of a Change of Control, all obligations hereunder shall be accelerated and such obligations shall be calculated as if an Early Termination Notice had been delivered on the Change of Control Date and shall include, but not be limited to the following: (a) payment of the Early Termination Payment calculated as if an Early Termination Notice had been delivered on such Change of Control Date, (b) payment of any Tax Benefit Payment in respect of a TRA Holder agreed to by the Corporation and such TRA Holder as due and payable but unpaid as of the Early Termination Notice, and (c) payment of any Tax Benefit Payment due for any Taxable Year ending prior to, with or including such Change of Control Date (except to the extent that the amount described in clause (c) is included in the Early Termination Payment). In the event of a Change of Control, the Early Termination Payment shall be calculated utilizing the Valuation Assumptions and by substituting in each case the term “Change of Control Date” for the term “Early Termination Date.”

14

Section 4.3 Breach of Agreement.

(a) In the event that the Corporation breaches any of its material obligations under this Agreement, whether as a result of failure to make any payment when due, as a result of failure to honor any other material obligation required hereunder or by operation of law as a result of the rejection of this Agreement in a case commenced under the Bankruptcy Code or otherwise, then, unless otherwise waived in writing by a majority of the TRA Holders, such breach shall be treated as an Early Termination and all obligations hereunder shall be accelerated and such obligations shall be calculated as if an Early Termination Notice had been delivered on the date of such breach and shall include, but shall not be limited to, (i) the Early Termination Payment calculated as if an Early Termination Notice had been delivered on the date of a breach, (ii) any Tax Benefit Payment previously due and payable but unpaid as of the date of the breach, and (iii) any Tax Benefit Payment due for any Taxable Year ending prior to, with or including the date of the breach (except to the extent that the amount described in clause (iii) is included in the Early Termination Payment). Notwithstanding the foregoing, in the event that the Corporation breaches any of its material obligations under this Agreement, a majority of the TRA Holders shall be entitled to elect to receive the amounts set forth in clauses (i), (ii), and (iii) above or to seek specific performance of the terms hereof.

(b) The parties agree that the failure to make any payment due pursuant to this Agreement within three (3) months of the date such payment is due shall be deemed to be a breach of a material obligation under this Agreement for all purposes of this Agreement, and that it shall not be considered to be a breach of a material obligation under this Agreement to make a payment due pursuant to this Agreement within three (3) months of the date such payment is due. The Corporation shall use its commercially reasonable efforts to maintain sufficient available funds for the purpose of making required payments under this Agreement and shall use its commercially reasonable efforts to avoid entering into credit agreements that could be reasonably anticipated to materially delay the timing of any payments under this Agreement. Notwithstanding anything in this Agreement to the contrary, it shall not be a breach of this Agreement if the Corporation fails to make any payment due pursuant to this Agreement as a result of and to the extent the Corporation has insufficient funds to make such payment; provided that the interest provisions of Section 5.2 shall apply to such late payment (unless the Corporation does not have sufficient cash to make such payment as a result of limitations imposed by debt agreements to which the Corporation or its Subsidiaries is a party, in which case Section 5.2 shall apply, but the Default Rate shall be replaced by the Agreed Rate); provided, further, that the Corporation shall promptly (and in any event, within two (2) Business Days), pay all such unpaid payments, together with accrued and unpaid interest thereon, immediately following such time that the Corporation has, and to the extent the Corporation has, sufficient funds to make such payment, and the failure of the Corporation to do so shall constitute a breach of this Agreement. For the avoidance of doubt, all cash and cash equivalents used or to be used to pay dividends by, or repurchase equity securities of, the Corporation shall be deemed to be funds sufficient and available to pay such unpaid payments, together with any accrued and unpaid interest thereon.

Section 4.4 Early Termination Notice. If the Corporation chooses to exercise its right of early termination under Section 4.1, the Corporation shall deliver to the Agent notice of such intention to exercise such right (the “Early Termination Notice”). Upon delivery of the Early

15

Termination Notice or the occurrence of an event described in Section 4.2 or Section 4.3(a), the Corporation shall deliver (i) a schedule showing in reasonable detail the calculation of the Early Termination Payment (the “Early Termination Schedule”) and (ii) any other work papers reasonably requested by the Agent. In addition, the Corporation shall allow the Agent reasonable access at no cost to the appropriate representatives of the Corporation in connection with a review of such Early Termination Schedule. The Early Termination Schedule shall become final and binding on all parties thirty (30) calendar days from the first date on which the Agent has received such Schedule or amendment thereto unless (x) the Agent, within thirty (30) calendar days after receiving the Early Termination Schedule, provides the Corporation and each other Agent with notice of a material objection to such Schedule made in good faith (“Material Objection Notice”) or (y) the Agent provides a written waiver of such right of a Material Objection Notice within the period described in clause (x) above, in which case such Schedule becomes binding on the date a waiver from the Agent has been received by the Corporation (the “Early Termination Effective Date”). If the Corporation and Agent, for any reason, are unable to successfully resolve the issues raised in such notice within thirty (30) calendar days after receipt by the Corporation of the Material Objection Notice, the Corporation and Agent shall employ the Reconciliation Procedures under Section 7.9.

Section 4.5 Payment upon Early Termination.

(a) Within three (3) calendar days after the Early Termination Effective Date, the Corporation shall pay to each TRA Holder its Early Termination Payment. Each such payment shall be made by check, by wire transfer of immediately available funds to a bank account or accounts designated by the TRA Holder, or as otherwise agreed by the Corporation and the TRA Holder.

(b) The “Early Termination Payment” shall equal, with respect to each TRA Holder, the present value, discounted at the Early Termination Rate as of the Early Termination Date, of all Tax Benefit Payments that would be required to be paid by the Corporation to such TRA Holder beginning from the Early Termination Date and assuming that the Valuation Assumptions are applied.

ARTICLE V

SUBORDINATION AND LATE PAYMENTS

Section 5.1 Subordination. Notwithstanding any other provision of this Agreement to the contrary, any Tax Benefit Payment, Early Termination Payment or any other payment required to be made by the Corporation to any TRA Holder under this Agreement shall rank subordinate and junior in right of payment to any principal, interest or other amounts due and payable in respect of any obligations in respect of indebtedness for borrowed money of the Corporation and its Subsidiaries (such obligations, “Senior Obligations”) and shall rank pari passu with all current or future unsecured obligations of the Corporation that are not Senior Obligations. For the avoidance of doubt, notwithstanding the above, the determination of whether it is a breach of this Agreement if the Corporation fails to make any Tax Benefit Payment when due is governed by Section 4.3(a).

Section 5.2 Late Payments by the Corporation. The amount of all or any portion of any Tax Benefit Payment, Early Termination Payment or any other payment under this Agreement not made to any TRA Holder when due under the terms of this Agreement shall be payable together with any interest thereon, computed at the Default Rate (or, if so provided in Section 4.3(a), at the Agreed Rate) and commencing from the date on which such Tax Benefit Payment, Early Termination Payment or any other payment under this Agreement was due and payable.

ARTICLE VI

PARTICIPATION IN TAX MATTERS; CONSISTENCY; COOPERATION

Section 6.1 Participation in the Corporation’s Tax Matters. Except as otherwise provided herein, the Corporation shall have full responsibility for, and sole discretion over, all Tax matters concerning the Corporation, including without limitation preparing, filing or amending any Tax Return and defending, contesting or settling any issue pertaining to Taxes of the Corporation. Notwithstanding the foregoing, the Corporation (i) shall notify the Agent of, and keep the Agent reasonably informed with respect to, the portion of any audit, examination, or any other administrative or judicial proceeding (a “Tax Proceeding”) of the Corporation by a Taxing Authority the outcome of which is reasonably expected to affect the rights and obligations of the TRA Holders under this Agreement, (ii) shall provide the Agent with reasonable opportunity to provide information and other input to the Corporation and its advisors concerning the conduct of any such portion of a Tax Proceeding, and (iii) shall not enter into any settlement with respect to any such portion of a Tax Proceeding that could have a material effect on the TRA Holders’ rights (including the right to receive payments) under this Agreement without the written consent of the Agent, such consent not to be unreasonably withheld, conditioned or delayed; provided, however, that the Corporation shall not be required to take any action, or refrain from taking any action, that is inconsistent with any provision of the LLC Agreement; provided, further, that, notwithstanding anything to the contrary contained herein, the Corporation shall prepare, file, and/or amend all Tax Returns in accordance with applicable law (including with respect to the calculation of taxable income and any calculations required to be made under this Agreement) and nothing in this Agreement shall prevent the Agent or any TRA Holder from disputing such Tax matters in accordance with Section 7.9.

Section 6.2 Consistency. The Corporation and the TRA Holders agree to report and cause to be reported for all purposes, including U.S. federal, state and local Tax purposes and financial reporting purposes, all Tax-related items (including, without limitation, the Basis Adjustments, Imputed Interest, and each Tax Benefit Payment), but, for financial reporting purposes, only in respect of items that are not explicitly characterized as “deemed” or in a similar manner by the terms of this Agreement, in a manner consistent with that set forth in any Schedule required to be provided by or on behalf of the Corporation under this Agreement, as finally determined pursuant to Section 2.4 unless otherwise required by applicable law. If the Corporation and any TRA Holder, for any reason, are unable to successfully resolve any disagreement concerning such treatment within thirty (30) calendar days, the Corporation and such TRA Holder shall employ the Reconciliation Procedures under Section 7.9.

Section 6.3 Cooperation. Each TRA Holder shall (i) furnish to the Corporation in a timely manner such information, documents and other materials as the Corporation may reasonably request for purposes of making any determination or computation necessary or appropriate under this Agreement, preparing any Tax Return or contesting or defending any Tax Proceeding, (ii) make itself available to the Corporation and its representatives to provide explanations of documents and materials and such other information as the Corporation or its representatives may reasonably request in connection with any of the matters described in clause (i) above, and (iii) reasonably cooperate in connection with any such matter. The Corporation shall reimburse the TRA Holder for any reasonable third-party costs and expenses incurred pursuant to this Section 6.3.

18

Section 7.3 Entire Agreement; No Third Party Beneficiaries. This Agreement constitutes the entire agreement and supersedes all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof. This Agreement shall be binding upon and inure solely to the benefit of each party hereto and their respective successors and permitted assigns, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, except as expressly provided in Section 3.3.

Section 7.4 Governing Law. This Agreement shall be governed by, and construed in accordance with, the law of the State of Delaware, without regard to the conflicts of laws principles thereof that would mandate the application of the laws of another jurisdiction.

Section 7.5 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

Section 7.6 Successors: Assignment. Each party agrees that each TRA Holder may assign, sell, transfer, delegate, or otherwise dispose of, whether voluntarily or involuntarily, or by operation of law, any right or obligation under this Agreement. Any purported assignment, transfer, or delegation in violation of this Section shall be null and void. This Agreement shall be binding upon and shall inure to the benefit of the parties and their respective successors and assigns. Except for those enumerated above, this Agreement does not create, and shall not be construed as creating, any rights or claims enforceable by any person or entity not a party to this Agreement. To the extent Units are transferred in accordance with the terms of the LLC Agreement, the transferring TRA Holder shall have the option to assign to the transferee of such Units the transferring TRA Holder’s rights under this Agreement as long as such transferee has executed and delivered, or, in connection with such transfer, executes and delivers, a joinder to this Agreement agreeing to become a “TRA Holder” for all purposes of this Agreement, and any and all payments payable or that may become payable to a TRA Holder pursuant to this Agreement that, once an Exchange has occurred, arise with respect to the Exchangeable Units transferred in such Exchange, may be assigned to any Person or Persons as long as any such Person has executed and delivered, or, in connection with such assignment, executes and delivers, a joinder to this Agreement agreeing to be bound by Section 7.14. For the avoidance of doubt, if a TRA Holder transfers Units but does not assign to the transferee of such Units such TRA Holder’s rights under this Agreement with respect to such transferred Units, such TRA Holder shall continue to be entitled to receive the Tax Benefit Payments arising in respect of a subsequent Exchange of such Units.

Section 7.7 Amendments: Waivers. No provision of this Agreement may be amended unless such amendment is approved in writing by each of the Corporation and by TRA Holders who would be entitled to receive more than fifty percent (50%) of the aggregate amount of the

19

Early Termination Payments payable to all TRA Holders hereunder if the Corporation had exercised its right of Early Termination on the date of the most recent Exchange prior to such amendment (excluding, for purposes of this sentence, all payments made to any TRA Holder pursuant to this Agreement since the date of such most recent Exchange); provided, however, that no such amendment shall be effective if such amendment would have a disproportionate effect on the payments certain TRA Holders will or may receive under this Agreement unless all such disproportionately affected TRA Holders consent in writing to such amendment.

Section 7.8 Titles and Subtitles. The titles of the sections and subsections of this Agreement are for convenience of reference only and are not to be considered in construing this Agreement.

Section 7.9 Reconciliation. In the event that the Corporation and the Agent or any TRA Holder (as applicable, the “Disputing Party”) are unable to resolve a disagreement with respect to the calculations required to produce the schedules described in Section 2.4, Section 4.4 and Section 6.2 within the relevant period designated in this Agreement (“Reconciliation Dispute”), the Reconciliation Dispute shall be submitted for determination to the Expert. The Expert shall be a partner or principal in a nationally recognized accounting or law firm, and unless the Corporation and the Disputing Party agree otherwise, the Expert shall not, and the firm that employs the Expert shall not, have any material relationship with the Corporation or the Disputing Party or other actual or potential conflict of interest. If the parties are unable to agree on an Expert within fifteen (15) calendar days of receipt by the respondents of written notice of a Reconciliation Dispute, the Expert shall be appointed by the International Chamber of Commerce Centre for Expertise. The Expert shall resolve (a) any matter relating to the Exchange Schedule or an amendment thereto or the Early Termination Schedule or an amendment thereto within thirty (30) calendar days, (b) any matter relating to a Tax Benefit Schedule or an amendment thereto within fifteen (15) calendar days, and (c) any matter related to treatment of any tax-related item as contemplated in Section 6.2 within fifteen (15) calendar days or, in each case, as soon thereafter as is reasonably practicable after such matter has been submitted to the Expert for resolution. Notwithstanding the preceding sentence, if the matter is not resolved before any payment that is the subject of a disagreement would be due (in the absence of such disagreement) or any Tax Return reflecting the subject of a disagreement is due, any portion of such payment that is not under dispute shall be paid on the date prescribed by this Agreement and such Tax Return may be filed as prepared by the Corporation, subject to adjustment or amendment upon resolution. The costs and expenses relating to the engagement of such Expert or amending any Tax Return shall be borne by the Corporation except as provided in the next sentence. The Corporation and the Disputing Party shall each bear its own costs and expenses of such proceeding, unless (i) the Expert adopts such Disputing Party’s position, in which case the Corporation shall reimburse such Disputing Party for any reasonable out-of-pocket costs and expenses in such proceeding, or (ii) the Expert adopts the Corporation’s position, in which case such Disputing Party shall reimburse the Corporation for any reasonable out-of-pocket costs and expenses in such proceeding. Any dispute as to whether a dispute is a Reconciliation Dispute within the meaning of this Section 7.9 shall be decided by the Expert. The Expert shall finally determine any Reconciliation Dispute and the determinations of the Expert pursuant to this Section 7.9 shall be binding on the Corporation and its Subsidiaries and the Disputing Party and may be entered and enforced in any court having jurisdiction.

20

Section 7.10 Consent to Jurisdiction. Each party hereto irrevocably submits to the exclusive jurisdiction of the United States District Court for the State of Delaware and the state courts of the State of Delaware for the purposes of any suit, action or other proceeding arising out of this Agreement or any transaction contemplated hereby. Each party hereto further agrees that service of any process, summons, notice or document by United States certified or registered mail (in each such case, prepaid return receipt requested) to such party’s respective address set forth in the Company’s books and records or such other address or to the attention of such other person as the recipient party has specified by prior written notice to the sending party shall be effective service of process in any action, suit or proceeding in Delaware with respect to any matters to which it has submitted to jurisdiction as set forth above in the immediately preceding sentence. Each party hereto irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby in the United States District Court for the State of Delaware or the state courts of the State of Delaware and hereby irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in such court has been brought in an inconvenient forum.

Section 7.11 Waiver of Jury Trial. Because disputes arising in connection with complex transactions are most quickly and economically resolved by an experienced and expert person and the parties wish applicable state and federal laws to apply (rather than arbitration rules), the parties desire that their disputes be resolved by a judge applying such applicable laws. Therefore, to achieve the best combination of the benefits of the judicial system and of arbitration. Each party to this agreement (including the Company) hereby waives all rights to trial by jury in any action or proceeding brought to resolve any dispute between or among any of the parties hereto. Whether arising in contract, tort, or otherwise, arising out of, connected with, related or incidental to this agreement. The transactions contemplated hereby and/or the relationships established among the parties hereunder.

Section 7.12 Withholding. The Corporation shall be entitled to deduct and withhold from any payment payable pursuant to this Agreement such amounts as the Corporation is required to deduct and withhold with respect to the making of such payment under the Code or any provision of U.S. federal, state, local or non-U.S. Tax law. To the extent that amounts are so withheld and paid over to the appropriate Taxing Authority by the Corporation, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the relevant TRA Holder.

Section 7.13 Admission of the Corporation into a Consolidated Group; Transfers of Corporate Assets.

(a) If the Corporation becomes a member of an affiliated, consolidated, combined, or unitary group of corporations that files a consolidated, combined, or unitary income Tax Return pursuant to Sections 1501 et seq. of the Code or any corresponding provisions of U.S. state or local Tax law, or would be eligible to become a member of such a group at the election of one or members of that group, then, subject to the application of the Valuation Assumptions upon a Change of Control: (i) the provisions of this Agreement shall be applied with respect to the group as a whole; and (ii) Tax Benefit Payments, Early Termination Payments and other applicable items hereunder shall be computed with reference to the consolidated taxable income of the group as a whole.

21

(b) If any entity that is obligated to make a Tax Benefit Payment or Early Termination Payment hereunder or the Company or any Subsidiary of the Company transfers one or more assets to a corporation (or a Person classified as a corporation for Tax purposes) with which the Corporation does not file a consolidated Tax Return pursuant to Section 1501 of the Code or any provisions of state or local Tax law, such entity, for purposes of calculating the amount of any Tax Benefit Payment or Early Termination Payment (e.g., calculating the gross income of the entity and determining the Realized Tax Benefit or Realized Tax Detriment of such entity) due hereunder, shall be treated as having disposed of such asset in a fully taxable transaction on the date of such contribution. The consideration deemed to be received by such entity shall be equal to the fair market value of the contributed asset. Thus, for example, in determining the Hypothetical Tax Liability of the entity, the taxable income of the entity shall be determined by treating the entity as having sold the asset for its fair market value, recovering any basis applicable to such asset (using the Tax basis that such asset would have had at such time if no Basis Adjustments had been made), while the Actual Tax Liability of the entity would be determined by recovering the actual Tax basis of the asset that reflects any Basis Adjustments. For purposes of this Section 7.13, a transfer of a partnership interest shall be treated as a transfer of the transferring partner’s share of each of the assets and liabilities of that partnership. If any entity that is obligated to make a Tax Benefit Payment or Early Termination Payment hereunder or the Company or any Subsidiary of the Company transfers one or more assets to a partnership (or a Person classified as a partnership for Tax purposes), the principles of this Section 7.13(b) and this Agreement shall govern the treatment of such transfer and any subsequent allocations of income, gain, loss or deductions from such partnership to such entity.

Section 7.14 Confidentiality.

(a) The Agent, each TRA Holder and each of the TRA Holder’s assignees acknowledges and agrees that the information of the Corporation is confidential and, except in the course of performing any duties as necessary for the Corporation and its Affiliates, as required by law or legal process or to enforce the terms of this Agreement, such person shall keep and retain in the strictest confidence and not disclose to any Person any confidential matters, acquired pursuant to this Agreement, of the Corporation and its Affiliates and successors, concerning the Company and its Affiliates and successors or the TRA Holders, earned by the Agent or any TRA Holder heretofore or hereafter. This Section 7.14 shall not apply to (i) any information that has been made publicly available by the Corporation or any of its Affiliates, becomes public knowledge (except as a result of an act of the Agent or a TRA Holder in violation of this Agreement) or is generally known to the business community and (ii) the disclosure of information (A) as may be proper in the course of performing such TRA Holder’s obligations, or monitoring or enforcing such TRA Holder’s rights, under this Agreement, (B) as part of such TRA Holder’s normal reporting, rating or review procedure (including normal credit rating and pricing process), or in connection with such TRA Holder’s or such TRA Holder’s Affiliates’ normal fund raising, marketing, informational or reporting activities, or to such TRA Holder’s (or any of its Affiliates’) Affiliates, auditors, accountants, attorneys or other agents, (C) to any bona fide prospective assignee of such TRA Holder’s rights under this Agreement, or prospective merger or other business combination partner of such TRA Holder, provided that such assignee or merger partner agrees to be bound by the provisions of this Section 7.14. (D) as is required to be disclosed by order of a court of competent jurisdiction, administrative body or governmental body, or by subpoena, summons or legal process, or by law, rule or regulation; provided that any TRA Holder

22

required to make any such disclosure to the extent legally permissible shall provide the Corporation prompt notice of such disclosure, or to regulatory authorities or similar examiners conducting regulatory reviews or examinations (without any such notice to the Corporation), or (E) to the extent necessary for a TRA Holder to prepare and file its Tax Returns, to respond to any inquiries regarding such Tax Returns from any Taxing Authority or to prosecute or defend any Tax Proceeding with respect to such Tax Returns. Notwithstanding anything to the contrary herein, the Agent (and each employee, representative or other agent of Agent or its assignees, as applicable) and each TRA Holder and each of its assignees (and each employee, representative or other agent of such TRA Holder or its assignees, as applicable) may disclose to any and all Persons, without limitation of any kind, the Tax treatment and Tax structure of the Corporation, the Company, the Agent, the TRA Holders and their Affiliates, and any of their transactions, and all materials of any kind (including opinions or other Tax analyses) that are provided to the Agent or the TRA Holder relating to such Tax treatment and Tax structure.

(b) If the Agent or an assignee or a TRA Holder or an assignee commits a breach, or threatens to commit a breach, of any of the provisions of this Section 7.14 the Corporation shall have the right and remedy to have the provisions of this Section 7.14 specifically enforced by injunctive relief or otherwise by any court of competent jurisdiction without the need to post any bond or other security, it being acknowledged and agreed that any such breach or threatened breach shall cause irreparable injury to the Corporation or any of its Subsidiaries or the TRA Holders and the accounts and funds managed by the Corporation and that money damages alone shall not provide an adequate remedy to such Persons. Such rights and remedies shall be in addition to, and not in lieu of, any other rights and remedies available at law or in equity.

Section 7.15 No Similar Agreements. Neither the Corporation nor any of its Subsidiaries shall enter into any additional agreement providing rights similar to this Agreement to any Person (including any agreement pursuant to which the Corporation is obligated to pay amounts with respect to tax benefits resulting from any net operating losses or other tax attributes to which the Corporation becomes entitled as a result of a transaction) without the prior written consent of the TRA Holders who would be entitled to receive more than fifty percent (50%) of the aggregate amount of the Early Termination Payments payable to all TRA Holders hereunder if the Corporation had exercised its right of early termination on the date of the most recent Exchange (excluding, for purposes of this sentence, all payments made to any TRA Holder pursuant to this Agreement since the date of such most recent Exchange).

Section 7.16 Change in Law. Notwithstanding anything herein to the contrary, if, in connection with an actual or proposed change in law, a TRA Holder reasonably believes that the existence of this Agreement could cause income (other than income arising from receipt of a payment under this Agreement) recognized by such TRA Holder upon any Exchange to be treated as ordinary income rather than capital gain (or otherwise taxed at ordinary income rates) for U.S. federal income and all applicable state and local Tax purposes or would have other material adverse Tax consequences to the TRA Holder and/or its direct or indirect owners, then at the election of the TRA Holder and to the extent specified by the TRA Holder, this Agreement (i) shall cease to have further effect with respect to such TRA Holder, (ii) shall not apply to an Exchange by the TRA Holder occurring after a date specified by it, or (iii) shall otherwise be amended in a manner determined by the TRA Holder to waive any benefits to which such TRA Holder would otherwise be entitled under this Agreement, provided that such amendment shall not result in an increase in or acceleration of payments under this Agreement at any time as compared to the amounts and times of payments that would have been due in the absence of such amendment.

Notwithstanding anything to the contrary herein, neither the Corporation nor the Company shall effectuate a Cash Payment pursuant to this Section 2.1(a) or (b)Section 2.1(b) unless (A) the Corporation determines to consummate a private sale or public offering of Class A Common Stock on, or not later than five (5) Business Days after, the relevant Exchange Date and (B) the Corporation contributes sufficient proceeds from such private sale or public offering to the Company for payment by the Company of the applicable Cash Payment. For the avoidance of doubt, the Company shall have no obligation to make a Cash Payment that exceeds the cash contributed to the Company by the Corporation from the Corporation’s offering or sales of Class A Common Stock referenced earlier in this Section 2.1(a)(i).

(ii) Notwithstanding anything to the contrary contained herein, the Member shall not be entitled to effectuate an Exchange of Exchangeable Units (and a corresponding number of shares of Class B Common Stock after taking into account the Exchange Rate) as set forth in this Section 2.1(a), and the Corporation and Company shall have the right to refuse to honor any request for such an Exchange, if at any time the Corporation or the Company determines based on the advice of counsel that such Exchange (1) would be prohibited by law or regulation (including, without limitation, the unavailability of a registration of such Exchange under the Securities Act, or an exemption from the registration requirements thereof) or (2) would not be permitted under any agreement with the Corporation, the Company or any of their Subsidiaries to which the Member is party (including, without limitation, the LLC Agreement). Upon such determination, the Corporation or the Company (as applicable) shall notify the Member, which such notice shall include an explanation in reasonable detail as to the reason that the Exchange has not been honored.

(iii) The Member shall exercise its right to effectuate an Exchange of Exchangeable Units, and a corresponding number of shares of Class B Common Stock after taking into account the Exchange Rate, as set forth in this Section 2.1(a) by delivering to the Company, with a contemporaneous copy delivered to the Corporation, during normal business hours, (A) a written election of exchange in respect of the Exchangeable Units to be exchanged substantially in the form of Exhibit B hereto (an “Exchange Notice”), duly executed by the Member, (B) any

4

certificates in the Member’s possession representing such Exchangeable Units, (C) any stock certificates in the Member’s possession representing such shares of Class B Common Stock and (D) if the Corporation, the Company or any exchanging Subsidiary requires the delivery of the certification contemplated by Section 2.4(b), such certification or written notice from the Member that it is unable to provide such certification. Unless the Member timely has delivered a Retraction Notice pursuant to Section 2.1(a)(vi), an Exchange pursuant to this Section 2.1(a) shall be effected on the fifth Business Day following the Business Day on which the Corporation and the Company have received the items specified in clauses (A)-(D) of the first sentence of this Section 2.1(a)(iii) or such later date that is a Business Day specified in the Exchange Notice (such Business Day, the “Exchange Date”); provided, that the Company may establish alternate exchange procedures as necessary in order to facilitate the establishment by the Member of a trading plan meeting the requirements of Rule 10b5-1 under the Exchange Act. On the Exchange Date, all rights of the Member as a holder of the Exchangeable Units and shares of Class B Common Stock that are subject to the Exchange shall cease, and unless the Corporation has elected Cash Payment, the Member (or its designee) shall be treated for all purposes as having become the record holder of the shares of Class A Common Stock to be received by the Member in respect of such Exchange.

(iv) Within two (2) Business Days following the Business Day on which the Corporation and the Company have received the Exchange Notice, the Corporation shall give written notice (the “Contribution Notice”) to the Company (with a copy to the Member) of its intended settlement method; provided that if the Corporation does not timely deliver a Contribution Notice, the Corporation shall be deemed to have not elected the Cash Payment method.

(v) The Member may specify, in an applicable Exchange Notice, that the Exchange is to be contingent (including as to timing) upon the occurrence of any transaction or event, including the consummation of a purchase by another Person (whether in a tender or exchange offer, an underwritten offering, Change of Control transaction or otherwise) of shares of Class A Common Stock or any merger, consolidation or other business combination.

(vi) Notwithstanding anything herein to the contrary, the Member may withdraw or amend its Exchange Notice, in whole or in part, at any time prior to 5:00 p.m. San Diego, California time, on the Business Day immediately prior to the Exchange Date by giving written notice (a “Retraction Notice”) to the Company (with a copy to the Corporation) specifying (A) the number of withdrawn Exchangeable Units (and corresponding number of shares of Class B Common Stock after taking into account the Exchange Rate), (B) the number of Exchangeable Units (and corresponding number of shares of Class B Common Stock after taking into account the Exchange Rate) as to which the Exchange Notice remains in effect, if any, and (C) if the Member so determines, a new Exchange Date or any other new or revised information permitted in the Exchange Notice.

(b) Change of Control. In connection with a Change of Control, and subject to any approval of the Change of Control by the holders of Class A Common Stock and Class B Common Stock that may be required:

(i) The Corporation shall have the right to require the Member to effectuate an Exchange of some or all of the Member’s Exchangeable Units, and a corresponding number of shares of Class B Common Stock after taking into account the Exchange Rate (in each case, free and clear of all Liens), with the Corporation or, at the option of the Corporation, with any Subsidiary of the Corporation, in each case, in exchange for the delivery to the Member (or its designee) of a number of shares of Class A Common Stock that is equal to the product of the applicable Exchanged Unit Amount and the Exchange Rate (such Exchange, a “Change of Control

5

Exchange”); provided that, if the Corporation requires the Member to Exchange less than all of its outstanding Exchangeable Units (and corresponding number of shares of Class B Common Stock after taking into account the Exchange Rate), the Member’s participation in the required Exchange shall be reduced pro rata based on ownership of Exchangeable Units. For the avoidance of doubt, any Exchangeable Units and a corresponding number of shares of Class B Common Stock held by the Member that are not Exchanged pursuant to a Change of Control Exchange may be Exchanged by the Member after the Change of Control transaction pursuant to Section 2.1(a) subject to and in accordance with the terms thereof.

(ii) The election of the Corporation pursuant to this Section 2.1(b) shall be at the sole discretion of the Corporation upon the approval thereof by a majority of the Board of Directors of the Corporation.

(iii) Any Exchange pursuant to this Section 2.1(b) shall be effective immediately prior to the consummation of the Change of Control (and, for the avoidance of doubt, shall not be effective if such Change of Control is not consummated) (the “Change of Control Exchange Date”). From and after the Change of Control Exchange Date, (x) the Exchangeable Units and shares of Class B Common Stock Exchanged pursuant to this Section 2.1(b) shall be deemed to be transferred to the Corporation, or the exchanging Subsidiary, as applicable, on the Change of Control Exchange Date and (y) the Member shall cease to have any rights with respect to the Exchangeable Units and shares of Class B Common Stock Exchanged pursuant to this Section 2.1(b) (other than the right to receive shares of Class A Common Stock pursuant to Section 2.1(b)(i) upon compliance with its obligations under Section 2.1(c)).

(iv) The Corporation shall provide written notice of an expected Change of Control to the Member within the earlier of (x) five (5) Business Days following the execution of the agreement with respect to such Change of Control and (y) ten (10) Business Days before the proposed date upon which the contemplated Change of Control is to be effected, indicating in such notice such information as may reasonably describe the Change of Control transaction, subject to applicable law, including the date of execution of such agreement or such proposed effective date, as applicable, the amount and types of consideration to be paid for Exchangeable Units and shares of Class B Common Stock or shares of Class A Common Stock, as applicable, in the Change of Control (which consideration shall be equivalent whether paid for Exchangeable Units and shares of Class B Common Stock or shares of Class A Common Stock), any election with respect to types of consideration that a holder of Exchangeable Units and shares of Class B Common Stock or shares of Class A Common Stock, as applicable, shall be entitled to make in connection with the Change of Control, the percentage of total Exchangeable Units and shares of Class B Common Stock or shares of Class A Common Stock, as applicable, to be transferred to the acquirer by all shareholders in the Change of Control, and the number of Exchangeable Units and shares of Class B Common Stock held by the Member that the Corporation intends to require to be Exchanged for shares of Class A Common Stock in connection with the Change of Control. The Corporation shall update such notice from time to time to reflect any material changes to such notice. The Corporation may satisfy any such notice and update requirements described in the preceding two sentences by providing such information on a Form 8-K, Schedule TO, Schedule 14D-9, Preliminary Merger Proxy on Schedule 14A, Definitive Merger Proxy on Schedule 14A or similar form filed with the SEC.

(c) Exchange Procedure on Change of Control Exchange. On or prior to the Change of Control Exchange Date, the Member shall deliver to the Corporation or the exchanging Subsidiary, as applicable, with a contemporaneous copy delivered to the Company, in each case during normal business hours at the principal executive offices of the Company and the

Corporation, respectively: (A) an Exchange Notice, duly executed by the Member, (B) any certificates in the Member’s possession representing all Exchangeable Units being surrendered by the Member, (C) any stock certificates in the Member’s possession representing all shares of Class B Common Stock being surrendered by the Member and (D) if the Corporation, the Company or the exchanging Subsidiary requires the delivery of the certification contemplated by Section 2.4(b), such certification or written notice from the Member that it is unable to provide such certification.

(d) Exchange Consideration. As promptly as practicable on or after the Exchange Date or Change of Control Exchange Date, as applicable, provided the Member has satisfied its obligations under Section 2.1(a)(iii) or Section 2.1(c), as applicable, the Company or the Corporation shall deliver or cause to be delivered to the Member (or its designee), either certificates or evidence of book-entry shares representing the number of shares of Class A Common Stock deliverable upon the applicable Exchange, registered in the name of the Member (or its designee) or, if the Corporation has so elected, the Cash Payment. Notwithstanding anything set forth in this Section 2.1(d) to the contrary, to the extent the Class A Common Stock issued in the exchange will be settled through the facilities of The Depository Trust Company, the Company or the Corporation will, upon the written instruction of the Member, deliver the shares of Class A Common Stock deliverable to the Member through the facilities of The Depository Trust Company to the account of the participant of The Depository Trust Company designated by the Member in the Exchange Notice. Upon the Member exercising its right to Exchange in accordance with Section 2.1(a)(i) or the occurrence of a Change of Control Exchange, the Company or the Corporation shall take such actions as (A) may be required to ensure that the Member receives the shares of Class A Common Stock or the Cash Payment that the Member is entitled to receive in connection with such Exchange pursuant to this Section 2.1, and (B) may be reasonably within its control that would cause such Exchange to be treated for purposes of the Tax Receivable Agreement as an “Exchange” under the Tax Receivable Agreement.

(e) Legends.

(i) The shares of Class A Common Stock issued upon an Exchange, other than any such shares issued in an Exchange subject to an effective registration statement under the Securities Act, shall bear a legend in substantially the following form:

THE TRANSFER OF THESE SECURITIES HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR UNDER THE SECURITIES LAWS OF ANY OTHER JURISDICTION, AND MAY NOT BE SOLD OR TRANSFERRED OTHER THAN IN ACCORDANCE WITH THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933, AS AMENDED (OR OTHER APPLICABLE LAW), OR AN EXEMPTION THEREFROM.

(ii) If (A) any shares of Class A Common Stock have been sold pursuant to a registration statement that has been declared effective by the SEC, (B) all of the applicable conditions of Rule 144 are met, or (C) the legend (or a portion thereof) otherwise ceases to be applicable, the Corporation, upon the written request of the holder thereof, shall promptly provide such holder or its respective transferees with new certificates (or evidence of book-entry share) for securities of like tenor not bearing the provisions of the legend with respect to which the restriction has terminated. In connection therewith, such holder shall provide the Corporation with such information in its possession as the Corporation may reasonably request (which may include an opinion of counsel reasonably acceptable to the Corporation) in connection with the removal of any such legend.

7

(f) Cancellation of Class B Common Stock. Any shares of Class B Common Stock surrendered in an Exchange shall automatically be deemed cancelled without any action on the part of any Person, including the Corporation. Any such cancelled shares of Class B Common Stock shall no longer be outstanding, and all rights with respect to such shares shall automatically cease and terminate.

(g) Expenses. Subject to any other arrangement or agreement among the Company and an applicable Member, the Corporation, the Company, any exchanging Subsidiary and the Member shall bear their own expenses in connection with the consummation of any Exchange, whether or not any such Exchange is ultimately consummated, except that the Corporation shall bear any transfer taxes, stamp taxes or duties, or other similar taxes in connection with, or arising by reason of, any Exchange; provided, however, that if any shares of Class A Common Stock are to be delivered in a name other than that of the Member that requested the Exchange (or The Depository Trust Company or its nominee for the account of a participant of The Depository Trust Company that will hold the shares for the account of the Member) or the Cash Payment is to be paid to a Person other than the Member that requested the Exchange, then the Member or the Person in whose name such shares are to be delivered or to whom the Cash Payment is to be paid shall pay to the Corporation the amount of any transfer taxes, stamp taxes or duties, or other similar taxes in connection with, or arising by reason of, such Exchange or shall establish to the reasonable satisfaction of the Corporation that such tax has been paid or is not payable.

(h) Publicly Traded Partnership. Notwithstanding anything to the contrary herein, if the Manager of the Company, after consultation with its outside legal counsel and tax advisor, shall determine in good faith that interests in the Company do not meet the requirements of Treasury Regulation Section 1.7704-1(h) (or other provisions of those Regulations as determined by the Manager in its sole discretion), the Company may impose such restrictions on Exchanges as the Company may reasonably determine to be necessary or advisable so that the Company is not treated as a “publicly traded partnership” under Section 7704 of the Code.

Section 2.2 Adjustment.

The Exchange Rate shall be adjusted accordingly if there is: (a) any subdivision (by any stock or unit split, stock or unit dividend or distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse stock or unit split, reclassification, reorganization, recapitalization or otherwise) of the shares of Class B Common Stock or Common Units that is not accompanied by a substantively identical subdivision or combination of the Class A Common Stock; or (b) any subdivision (by any stock or unit split, stock or unit dividend or distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse stock or unit split, reclassification, reorganization, recapitalization or otherwise) of the shares of Class A Common Stock that is not accompanied by a substantively identical subdivision or combination of the shares of Class B Common Stock or Common Units. To the extent not reflected in an adjustment to the Exchange Rate, if there is any reclassification, reorganization, recapitalization or other similar transaction in which the Class A Common Stock is converted or changed or exchanged into or for another security, securities or other property, then upon any subsequent Exchange, the Member shall be entitled to receive the amount of such security, securities or other property that the Member would have received if such Exchange had occurred immediately prior to the effective date of such reclassification, reorganization, recapitalization or other similar transaction, taking into account any adjustment as a result of any subdivision (by any split, distribution or dividend, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse split,

8

reclassification, recapitalization or otherwise) of such security, securities or other property that occurs after the effective time of such reclassification, reorganization, recapitalization or other similar transaction. For the avoidance of doubt, if there is any reclassification, reorganization, recapitalization or other similar transaction in which the Class A Common Stock is converted or changed or exchanged into or for another security, securities or other property, this Section 2.2 shall continue to be applicable, mutatis mutandis, with respect to such security or other property.

(a) The Corporation shall at all times reserve and keep available out of its authorized but unissued Class A Common Stock, solely for the purpose of issuance upon an Exchange, such number of shares of Class A Common Stock as shall be sufficient to effect the conversion of all outstanding Common Units; provided, however, that nothing contained herein shall be construed to preclude the Corporation from satisfying its obligations in respect of any such Exchange by delivery of unencumbered purchased shares of Class A Common Stock (which may or may not be held in the treasury of the Corporation or any subsidiary thereof).

(b) The Corporation has taken and will take all such steps as may be required to cause to qualify for exemption under Rule 16b-3(d) or (e), as applicable, under the Exchange Act, and be exempt for purposes of Section 16(b) under the Exchange Act, any acquisitions or dispositions of equity securities of the Corporation (including derivative securities with respect thereto) and any securities that may be deemed to be equity securities or derivative securities of the Corporation for such purposes that result from the transactions contemplated by this Agreement, by each director or officer of the Corporation (including directors-by-deputization) who may reasonably be expected to be subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Corporation upon the registration of any class of equity security of the Corporation pursuant to Section 12 of the Exchange Act (with the authorizing resolutions specifying the name of each such officer or director whose acquisition or disposition of securities is to be exempted and the number of securities that may be acquired and disposed of by each such Person pursuant to this Agreement).

(c) If any Takeover Law or other similar law or regulation becomes or is deemed to become applicable to this Agreement or any of the transactions contemplated hereby, the Corporation shall use its reasonable best efforts to render such law or regulation inapplicable to all of the foregoing.

(d) The Corporation covenants that all shares of Class A Common Stock issued upon an Exchange will, upon issuance, be validly issued, fully paid and non-assessable and not subject to any preemptive right of stockholders of the Corporation or to any right of first refusal or other right in favor of any Person.

Section 2.4 Withholding; Certification of Non-Foreign Status.

(a) If the Corporation or the Company shall be required to withhold any amounts by reason of any federal, state, local or foreign tax rules or regulations in respect of any Exchange, the Corporation or the Company, as the case may be, shall be entitled to take such action as it deems appropriate in order to ensure compliance with such withholding requirements, including, at its option, withholding shares of Class A Common Stock with a fair market value equal to the minimum amount of any taxes that the Corporation or the Company, as the case may be, may be required to withhold with respect to such Exchange. To the extent that amounts are (or property is) so withheld and paid over to the appropriate taxing authority, such withheld amounts (or property) shall be treated for all purposes of this Agreement as having been paid (or delivered) to the Member.

9

(b) Notwithstanding anything to the contrary herein, each of the Corporation and the Company may, in its discretion, require that the Member deliver to the Corporation or the Company, as the case may be, a duly completed and executed IRS Form W-9) prior to an Exchange. In the event the Corporation or the Company has required delivery of such form but the Member does not provide such form, the Corporation or the Company, as the case may be, shall nevertheless deliver or cause to be delivered to the Member the Class A Common Stock or the Cash Payment in accordance with Section 2.1, but subject to withholding as provided in Section 2.4(a).

Section 2.5 Tax Treatment.

Unless otherwise required by applicable law, the parties hereto acknowledge and agree that any Exchange with the Company or the Corporation shall be treated as a direct exchange between the Corporation and the Member for U.S. federal and applicable state and local income tax purposes. The parties hereto intend to treat any Exchange consummated hereunder as a taxable sale of the Exchangeable Units and Class B Common Stock (if any) by the Member to the Corporation for U.S. federal and applicable state and local income tax purposes except as otherwise mutually agreed to in writing by the Member and the Corporation and no party hereto shall take a position inconsistent with such intended tax treatment on any tax return, amendment thereof or any other communication with a taxing authority, in each case unless otherwise required by a “determination” within the meaning of Section 1313 of the Code.

Section 2.6 Contribution of the Corporation.

In connection with any Exchange between the Member and the Company, the Corporation shall contribute to the Company the shares of Class A Common Stock or Cash Payment that the Member is entitled to receive in such Exchange. Unless the Member has timely delivered a Retraction Notice as provided in Section 2.1(a)(vi), on the Exchange Date (to be effective immediately prior to the close of business on the Exchange Date) (i) the Corporation shall make a capital contribution to the Company (in the form of the shares of Class A Common Stock or the Cash Payment that the Member is entitled to receive in such Exchange) required under this Section 2.6, (ii) the Company shall transfer such shares of Class A Common Stock or Cash Payment to the Member in redemption of such Member’s Units in the Company, and (iii) in the case of an Exchange for Class A Common Stock and/or the Cash Payment (as applicable), the Company shall issue to the Corporation a number of Common Units equal to the Exchanged Unit Amount surrendered by the Member.

Section 2.7 Distributions.

No Exchange will impair the right of the Member to receive any distribution for periods ending on or prior to the Exchange Date for such Exchange (but for which payment had not yet been made with respect to the Exchangeable Units in question at the time the Exchange is consummated); provided that, for purposes of this Section 2.7, the Member’s right to receive its pro rata portion of any distribution by the Company in respect of such periods shall not be deemed impaired to the extent that the Company has not paid the Corporation its pro rata portion of such distribution prior to the consummation of the applicable Exchange.

To the extent that the Member (or an applicable Permitted Transferee of the Member) validly transfers after the date hereof any or all of its Common Units and corresponding shares of Class B Common Stock after taking into account the Exchange Rate, to a Permitted Transferee of such Person or to any other Person in a transaction not in contravention of, and in accordance with, the LLC Agreement, then the transferee thereof shall have the right to execute and deliver a joinder to this Agreement, in the form attached hereto as Exhibit C. Upon execution of any such joinder, such transferee shall, with respect to such transferred Common Units and shares of Class B Common Stock, be entitled to all of the rights and bound by each of the obligations applicable to the relevant transferor hereunder; provided that the transferor shall remain entitled to all of the rights and bound by each of the obligations with respect to Common Units and shares of Class B Common Stock that were not so transferred.

The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application thereof to any Person or entity or any circumstance, is found to be invalid or unenforceable in any jurisdiction, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application thereof, in any other jurisdiction.

Section 4.4 Counterparts.

This Agreement and any amendments may be executed simultaneously in two or more counterparts and delivered via facsimile or .pdf, each of which shall be deemed an original and all of which, when taken together, shall constitute one and the same document. The signature of any party to any counterpart shall be deemed a signature to, and may be appended to, any other counterpart.

Section 4.5 Entire Agreement.

This Agreement together with the LLC Agreement and the Tax Receivables Agreement (a) constitutes the entire agreement and supersedes all other prior agreements, both written and oral, among the parties with respect to the subject matter hereof and (b) is not intended to confer upon any Person, other than the parties hereto and their Permitted Transferees, any rights or remedies hereunder.

Section 4.7 Governing Law.

This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

13

Section 4.8 Consent to Jurisdiction.

Each party hereto irrevocably submits to the exclusive jurisdiction of the United States District Court for the State of Delaware and the state courts of the State of Delaware for the purposes of any suit, action or other proceeding arising out of this Agreement or any transaction contemplated hereby.

Section 4.9 Waiver of Jury Trial.

BECAUSE DISPUTES ARISING IN CONNECTION WITH COMPLEX TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED BY AN EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE STATE AND FEDERAL LAWS TO APPLY (RATHER THAN ARBITRATION RULES), THE PARTIES DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE, TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF ARBITRATION, EACH PARTY TO THIS AGREEMENT (INCLUDING THE COMPANY) HEREBY WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE BETWEEN OR AMONG ANY OF THE PARTIES HERETO, WHETHER ARISING IN CONTRACT, TORT, OR OTHERWISE, ARISING OUT OF, CONNECTED WITH, RELATED OR INCIDENTAL TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREBY AND/OR THE RELATIONSHIPS ESTABLISHED AMONG THE PARTIES HEREUNDER.

The provisions of this Agreement may be amended only by the affirmative vote or written consent of each of (i) the Corporation, (ii) the Company and (iii) the Member. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

Section 4.11 Assignment.

Neither this Agreement nor any of the rights or obligations hereunder shall be assigned by any of the parties hereto without the prior written consent of the other parties. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors, assigns and Permitted Transferees.

Section 4.12 Specific Enforcement.

The parties hereto acknowledge that the remedies at law of the other parties for a breach or threatened breach of this Agreement would be inadequate and, in recognition of this fact, any party to this

14

Agreement, without posting any bond, and in addition to all other remedies that may be available, shall be entitled to equitable relief in the form of specific performance, a temporary restraining order, a temporary or permanent injunction or any other equitable remedy that may then be available.

Notwithstanding the foregoing, this Section 3.2(b) shall not apply to the issuance and distribution to holders of shares of Class A Common Stock of rights to purchase Equity Securities of Maravai Co. under a “poison pill” or similar shareholder’s rights plan (it being understood that (i) upon exchange of Exchangeable Units for Class A Common Stock pursuant to the Exchange Agreement, such Class A Common Stock would be issued together with any such corresponding right and (ii) in the event such rights to purchase Equity Securities of Maravai Co. are triggered, Maravai Co. will ensure that the holders of Common Units that have not been Exchanged prior to such time will be treated equitably vis-à -vis the holders of Class A Common Stock under such plan).

12

Stock vest or are forfeited, then a corresponding number of the Common Units (determined based upon the Exchange Rate then in effect) issued by the Company in accordance with the preceding provisions of this Section 3.2(d) shall automatically vest or be forfeited. Any cash or property held by Maravai Co. or the Company or on any of such Person’s behalf in respect of dividends paid on restricted shares of Class A Common Stock that fail to vest shall be returned to the Company upon the forfeiture of such restricted shares of Class A Common Stock.

If any shares of Class A Common Stock require registration with or approval of any Governmental Entity under any federal or state law before such shares may be issued upon an Exchange, Maravai Co. shall use reasonable efforts to cause the exchange of such shares of Class A Common Stock to be duly registered or approved, as the case may be. Maravai Co. shall list and use its reasonable efforts to maintain the listing of the Class A Common Stock required to be delivered upon any such Exchange prior to such delivery upon the national securities exchange upon which the outstanding shares of Class A Common Stock are listed at the time of such Exchange (it being understood that any such shares may be subject to transfer restrictions under applicable securities laws). Maravai Co. covenants that all shares of Class A Common Stock issued upon an Exchange will, upon issuance, be validly issued, fully paid and non-assessable.

(f) For purposes of this Section 3.2, “net proceeds” means gross proceeds to Maravai Co. from the issuance of Class A Common Stock or other securities less all reasonable bona fide out-of-pocket fees and expenses of Maravai Co., the Company and their respective Subsidiaries actually incurred in connection with such issuance.
