ARTICLE II

DETERMINATION OF REALIZED TAX BENEFIT

Section 2.01. Pre-IPO NOL Utilization. US NewCo, on the one hand, and LHI, on the other hand, acknowledge that the Taxable Entities may utilize the Pre-IPO NOLs to reduce the amount of Taxes that the Taxable Entities would otherwise be required to pay in the future.

Section 2.02. Tax Benefit Schedule. Within ninety (90) calendar days after the filing of the U.S. federal income Tax Return of US NewCo (or, in the case that US NewCo is a member of an affiliated or consolidated group of corporations that files a consolidated income Tax Return pursuant to Sections 1501 et seq. of the Code, the Tax Return of such group) for any federal Taxable Year (each such Taxable Year a “Subject Taxable Year,” each such filing date a “Specified Filing Date,” and such ninetieth day the “Schedule Delivery Date”), US NewCo shall provide to LHI a schedule showing, for US NewCo and for each Taxable Entity, in the case of any relevant Tax Return that has been filed after the IPO and prior to the Schedule Delivery Date and has not previously been the subject of this Section 2.02, in reasonable detail, (i) the calculation of the Realized Tax Benefit for the Subject Taxable Year, (ii) the calculation of any payment to be made to LHI pursuant to Article III with respect to the Subject Taxable Year, (iii) the calculation of any Realized Tax Benefit for the Taxable Year immediately preceding the Subject Taxable Year (the “Rollover Taxable Year”), in the case of any relevant Tax Return that was filed

following the Specified Filing Date relating to the Rollover Taxable Year, and (iv) the calculation of any payment to be made to LHI pursuant to Article III with respect to the Rollover Taxable Year (collectively a “Tax Benefit Schedule”). Concurrently US NewCo shall also deliver to LHI all supporting information (including work papers and valuation reports) reasonably necessary to support the calculation of such payment. The Schedule will become final as provided in Section 2.03(a) and may be amended as provided in Section 2.03(b) (subject to the procedures set forth in Section 2.03(a)).

Section 2.03. Procedures, Amendments.

(a)                                 Procedure. Whenever US NewCo delivers to LHI an applicable Schedule under this Agreement, including any Amended Schedule delivered pursuant to Section 2.03(b), and including any Early Termination Schedule or amended Early Termination Schedule, US NewCo shall also (x) deliver to LHI schedules, valuation reports, if any, and work papers providing reasonable detail regarding the preparation of the Schedule and an Advisory Firm Report related to such Schedule (the cost and expense of which shall be paid by US NewCo) and (y) allow LHI reasonable access at no cost to the appropriate representatives at each of US NewCo and the Advisory Firm in connection with a review of such Schedule. The applicable Schedule shall become final and binding on all parties unless LHI, within thirty calendar days (or a shorter period agreed by US NewCo and LHI in writing after receiving any Schedule or amendment thereto, provides US NewCo with notice of a material objection to such Schedule or amendment, as applicable, made in good faith (“Objection Notice”). If the parties, for any reason, are unable to successfully resolve the issues raised in any Objection Notice within thirty calendar days of receipt by US NewCo of such Objection Notice, US NewCo and LHI shall employ the reconciliation procedures described in Section 7.09 of this Agreement (the “Reconciliation Procedures”).

(b)                                 Amended Schedule. The applicable Schedule for any Taxable Year may be amended from time to time by US NewCo (i) in connection with an audit of a Tax Return by an applicable Tax Authority for which a Determination has been made affecting such Schedule, (ii) to correct material 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 LHI, (iii) to comply with the Expert’s determination under the Reconciliation Procedures, or (iv) to reflect a material change (relative to the amounts in the original Schedule) in the Realized Tax Benefit for such Taxable Year attributable to an amended Tax Return filed for such Taxable Year, in each case with respect to any Taxable Entity (such amended Schedule, an “Amended Schedule”) of a Tax Return by an applicable Taxing Authority shall not be taken into account on an Amended Schedule unless and until. US NewCo shall provide any Amended Schedule to LHI within thirty calendar days of the occurrence of an event referred to in clauses (i) through (iv) of the preceding sentence, and any such Amended Schedule shall be subject to the approval procedures described in Section 2.03(a).

ARTICLE III

TAX BENEFIT PAYMENTS

Section 3.01. Payments.

(a)                                 Except as provided in Section 5.02, within thirty days after the end of any Subject Taxable Year, US NewCo (on its own behalf and on behalf of any other Taxable Entity) shall pay to LHI the Interest Amount (as defined below) and the Annual Tax Payment for the Subject Taxable Year. The “Annual Tax Payment” for a Subject Taxable Year means an amount, not less than zero, equal to (i) the Estimated Tax Benefit determined pursuant to Section 3.01(c) for such Subject Taxable Year, plus (ii) the excess, if any, of the Tax Benefit for a Subject Taxable Year prior to the Subject Taxable Year over the Estimated Tax Benefit for such prior Subject Taxable Year, to the extent any such excess amount was not previously taken into account pursuant to this Section 3.01(a)(ii) to increase the Annual Tax Payment for a Subject Taxable Year prior to the Subject Taxable Year, minus (iii) the excess, if any, of the Estimated Tax Benefit for a Subject Taxable Year prior to the Subject Taxable Year over the Tax Benefit for such prior Subject Taxable Year, to the extent any such excess amount was not previously taken into account pursuant to this Section 3.01(a)(iii) to reduce the Annual Tax Payment for a Subject Taxable Year prior to the Subject Taxable Year, plus (iv) the excess of the Realized Tax Benefit required to be reflected on an Amended Schedule for a Subject Taxable Year prior to the Subject Taxable Year over the Realized Tax Benefit required to be reflected on the Tax Benefit Schedule for such prior Subject Taxable Year, to the extent any such excess amount was not previously taken into account pursuant to this Section 3.01(a)(iv) to increase the Annual Tax Payment for a Subject Taxable Year prior to the Subject Taxable Year, minus (v) the excess of the Realized Tax Benefit required to be reflected on a Tax Benefit Schedule for a Subject Taxable Year prior to the Subject Taxable Year over the Realized Tax Benefit required to be reflected on an Amended Schedule for such prior Subject Taxable Year, to the extent any such excess amount was not previously taken into account pursuant to this Section 3.01(a)(v) to reduce the Annual Tax Payment for a Subject Taxable Year prior to the Subject Taxable Year. For the avoidance of doubt, no Annual Tax Payment shall be made, nor Tax Benefit determined, in respect of estimated tax payments. For the further avoidance of doubt, LHI shall not be required to return any portion of any previously made Annual Tax Payment or other ITR Payment. The “Interest Amount” shall equal the interest on any excess amount described in Section 3.01(a)(ii) calculated at the Agreed Rate from the Payment Date for the Annual Tax Payment in which the relevant Estimated Tax Benefit is taken into account until the Payment Date for the Annual Tax Payment in which the relevant Tax Benefit is taken into account. Each payment pursuant to this Section 3.01(a) shall be made by wire transfer of immediately available funds to a bank account of LHI previously designated by LHI to US NewCo or as otherwise agreed by US NewCo and LHI.

(b)                                 A “Tax Benefit” for a Subject Taxable Year means an amount, not less than zero, equal to 85% of: (i) the Taxable Entities’ Realized Tax Benefit, if any, required to be reflected on the Tax Benefit Schedule for the Subject Taxable Year , plus (ii) the Taxable Entities’ Realized Tax Benefit, if any, for the Rollover Taxable Year, if any, to the extent required to be reflected on the Tax Benefit Schedule for the Subject Taxable Year (as set forth in Section 2.02(iii)).

(c)                                  The “Estimated Tax Benefit” for a Subject Taxable Year means an amount, not less than zero, equal to 85% of US NewCo’s reasonable good faith estimate of the Taxable Entities’ Realized Tax Benefit, if any, for the Subject Taxable Year.

Section 3.02. 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 provide that 85% of the Taxable Entities’ Realized Tax Benefit for all Taxable Years be paid to LHI pursuant to this Agreement. Carryovers or carrybacks of any NOL or other tax item shall be considered to be subject to the rules of the Code and the Treasury Regulations or the appropriate provisions of state or local Tax law, as applicable, governing the use, limitation and expiration of carryovers or carrybacks of the relevant type; provided, however, that Pre-IPO NOLs treated as resulting in a Realized Tax Benefit for one Taxable Year shall not be treated as resulting in a Realized Tax Benefit for any other Taxable Year, and, for purposes of determining the Realized Tax Benefit for any Taxable Year, each Taxable Entity shall be assumed (a) to utilize any item of loss, deduction or credit arising in such Taxable Year (and permitted to be utilized in such Taxable Year) before carrying back or carrying forward to such Taxable Year any NOL that is permitted to be so carried back or carried forward, (b) to utilize any available Pre-IPO NOL that is permitted (or, for the absence of doubt, that would be so permitted but for such Other NOL) to be carried back or carried forward to such Taxable Year before utilizing any Other NOL, and (c) to utilize any Pre-IPO NOL in the first Taxable Year in which such Pre-IPO NOL is permitted to be utilized; provided, further, however, that, notwithstanding any other provision, the Chief Executive Officer of US NewCo, the Board and LHI shall, acting reasonably, together determine the extent to which a Pre-IPO NOL can be carried back or carried forward to a Straddle Year or any portion thereof. If a carryover or carryback of any Tax item includes a portion that is attributable to the Pre-IPO NOLs and another portion that is not, US NewCo shall be assumed to utilize the portion attributable to the Pre-IPO NOLs before utilizing such other portion. The provisions of this Agreement shall be construed in the appropriate manner so that such intentions are realized.

ARTICLE IV

TERMINATION

Section 4.01. Termination, Breach of Agreement, Change of Control.

(a)                                 This Agreement shall terminate at the time that all Annual Tax Payments have been made to LHI under this Agreement.

(b)                                 In the event that US NewCo breaches any of its material obligations under this Agreement, whether as a result of failure to make any payment when due (as described below), 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 all obligations hereunder shall be accelerated and US NewCo shall pay to LHI (1) the Early Termination Payment, (2) any Annual Tax Payment agreed to by US NewCo and LHI as due and payable but unpaid as of the Early Termination Date and (3) any Annual Tax Payment due for the Taxable Year ending prior to, with or including the date of a breach.

Notwithstanding the foregoing, in the event that US NewCo breaches this Agreement, LHI shall be entitled to elect to receive the amounts set forth in (1), (2) and (3) above or to seek specific performance of the terms hereof. In the event of a breach of a material obligation under this Agreement, the Early Termination Payment shall be calculated utilizing the Valuation Assumptions. The parties agree that the failure to make any payment due pursuant to this Agreement within six 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 will not be considered to be a breach of a material obligation under this Agreement to make a payment due pursuant to this Agreement within six months of the date such payment is due, provided that in the event that payment is not made within six months of the date such payment is due, LHI shall be required to give written notice to US NewCo that US NewCo has breached its material obligations and so long as such payment is made within five Business Days of the delivery of such notice to US NewCo, US NewCo shall no longer be deemed to be in material breach of its obligations under this Agreement.

(c)                                  Change of Control. In the event of a Change of Control, then all obligations hereunder shall be accelerated and US NewCo shall pay to LHI (1) the Early Termination Payment, (2) any Annual Tax Payment agreed to by US NewCo and LHI as due and payable but unpaid as of the Early Termination Date and (3) any Annual Tax Payment due for any Taxable Year ending prior to, with or including the effective date of a Change of Control. In the event of a Change of Control, the Early Termination Payment shall be calculated utilizing the Valuation Assumptions.

(d)                                 Divestiture Acceleration Payment. In the event of a Divestiture, US NewCo shall pay to LHI the Divestiture Acceleration Payment in respect of such Divestiture, which shall be calculated utilizing the Valuation Assumptions.

Section 4.02. Early Termination Schedule. In the event of a Change of Control or a Divestiture, US NewCo shall deliver to LHI no later than sixty calendar days prior to such Change of Control or Divestiture, as applicable a schedule (the “Early Termination Schedule”) showing in reasonable detail the information required pursuant to the penultimate sentence of Section 2.02 and the calculation of the Early Termination Payment or the Divestiture Acceleration Payment, respectively (including the projections of the Taxable Entities’ taxable income under clause (i) of the Valuation Assumptions). The Early Termination Schedule shall become final and binding on all parties unless LHI, within fifteen calendar days after receiving the Early Termination Schedule provides US NewCo with notice of a material objection to such Schedule made in good faith (“Material Objection Notice”). If the parties for any reason are unable to successfully resolve the issues raised in such Material Objection Notice within fifteen calendar days after receipt by US NewCo of the Material Objection Notice, US NewCo and LHI shall employ the Reconciliation Procedures as described in Section 7.09 of this Agreement.

Section 4.03. Payment upon Early Termination. (a) Except as provided in Section 5.02, no later than the Early Termination Date, US NewCo shall pay to LHI an amount equal to the Early Termination Payment or Divestiture Acceleration Payment and any other payment required to be made pursuant to Sections 4.01(b) and (c). Such payment shall be made by wire transfer of immediately available funds to a bank account designated by LHI or as otherwise agreed by US NewCo and LHI.

(b)                                 The “Early Termination Payment” as of the Early Termination Date (other than an Early Termination Date arising under clause (iii) of the definition thereof) shall equal with respect to LHI the present value, discounted at the Early Termination Rate as of such date, of all Annual Tax Payments that would be required to be paid by US NewCo to LHI for Taxable years ending on or after the Early Termination Date assuming the Valuation Assumptions are applied, provided that in the event of a Change of Control, the Early Termination Payment shall be calculated without giving effect to any limitation on the use of the Pre-IPO NOLs resulting from the Change of Control. For purposes of calculating the present value pursuant to this Section 4.03(b) of all Annual Tax Payments that would be required to be paid, it shall be assumed that absent the Early Termination Event all Annual Tax Payments would be paid on the due date (without extensions) for filing the relevant Taxable Entity Return with respect to Taxes for each Taxable Year. The computation of the Early Termination Payment is subject to the Reconciliation Procedures as described in Section 7.09 of this Agreement.

(c)                                  The “Divestiture Acceleration Payment” as of the date of any Divestiture shall equal with respect to LHI the present value, discounted at the Early Termination Rate as of such date, of the Annual Tax Payments resulting solely from the Transferred NOLs that would be required to be paid by US NewCo to LHI beginning from the date of such Divestiture assuming the Valuation Assumptions are applied, provided that the Divestiture Acceleration Payment shall be calculated without giving effect to any limitation on the use of the Transferred NOLs resulting from the Divesture. For purposes of calculating the present value pursuant to this Section 4.03(c) of all Annual Tax Payments that would be required to be paid, it shall be assumed that absent the Divestiture all Annual Tax Payments would be paid on the due date (without extensions) for filing the relevant Taxable Entity Return with respect to Taxes for each Taxable Year. The computation of the Divestiture Acceleration Payment is subject to the Reconciliation Procedures as described in Section 7.09 of this Agreement.

Section 7.09. Reconciliation.

(a)                                 In General. In the event that US NewCo and LHI are unable to resolve a disagreement with respect to the matters governed by Sections 2.03, 4.02 and 6.02 within the relevant period designated in this Agreement (or the amount of an Early Termination Payment in

the case of a breach to which Section 4.01(b) applies) (“Reconciliation Dispute”), the Reconciliation Dispute shall be submitted for determination to a nationally recognized expert (the “Expert”) in the particular area of disagreement mutually acceptable to both parties. The Expert shall be a partner in a nationally recognized accounting firm or a law firm (other than the Advisory Firm), and the Expert shall not, and the firm that employs the Expert shall not, have any material relationship with US NewCo or LHI or other actual or potential conflict of interest. If the parties are unable to agree on an Expert within fifteen (15) days of receipt by the respondent(s) of written notice of a Reconciliation Dispute, the Expert shall be appointed by the International Institute for Conflict Prevention and Resolution. The Expert shall resolve any matter relating to the Early Termination Schedule or an amendment thereto within thirty calendar days and shall resolve any matter relating to a Tax Benefit Schedule or an amendment thereto within fifteen calendar days or as soon thereafter as is reasonably practicable, in each case after the 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 is due or any Tax Return reflecting the subject of a disagreement is due, such payment shall be made on the date prescribed by this Agreement and such Tax Return may be filed as prepared by US NewCo or the relevant Taxable Entity, 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 US NewCo, except as provided in the next sentence. Each of US NewCo and LHI shall bear their own costs and expenses of such proceeding. Any dispute as to whether a dispute is a Reconciliation Dispute within the meaning of this Section 7.09 shall be decided by the Expert. The Expert shall finally determine any Reconciliation Dispute and the determinations of the Expert pursuant to this Section 7.09 shall be binding on US NewCo and LHI and may be entered and enforced in any court having jurisdiction.

(b)                                 Income Projections for Early Termination Payments. Notwithstanding the provisions of Section 7.09(a), solely with respect to disagreements regarding the computation of an Early Termination Payment or Divestiture Acceleration Payment that relates to the taxable income projections described in clause (i) of the definition of “Valuation Assumptions,” US NewCo and LHI shall each submit the Reconciliation Dispute for determination to an Expert in the area of valuation services. Based on the income projections of such Experts, if the higher of the resulting Early Termination Payment or Divestiture Acceleration Payment computations does not exceed 110% of the lower, then the Early Termination Payment or Divestiture Acceleration Payment shall be the average of such two amounts. If the higher of the Early Termination Payment or Divestiture Acceleration Payment computations is more than 110% of the lower, then the two Experts shall, within 20 days from such determination, select a third Expert and shall notify US NewCo and LHI of such selection. If the Early Termination Payment or Divestiture Acceleration Payment computed by the third Expert is equal to the average of the first two Early Termination Payment or Divestiture Acceleration Payment computations, then the Early Termination Payment or Divestiture Acceleration Payment shall be such average. If the third Early Termination Payment or Divestiture Acceleration Payment computation is higher than the average of the first two computations, then the Early Termination Payment or the Divestiture Acceleration Payment shall be the average of such third computation and the higher of the first two computations; provided that if such average exceeds 110% of the higher of the first two computations, then the Early Termination Payment or Divestiture Acceleration Payment shall be 110% of the higher of the first two computations. If the third Early Termination Payment or Divestiture Acceleration Payment computation is lower than the average of the first two

computations, then the Early Termination Payment or Divestiture Acceleration Payment shall be the average of such third computation and the lower of the first two computations; provided that if such average is less than 90% of the lower of the first two computations, then the Early Termination Payment or Divestiture Acceleration Payment shall be 90% of the lower of the first two computations.

Section 7.10. Withholding. US NewCo shall be entitled to deduct and withhold from any payment payable pursuant to this Agreement such amounts as US NewCo is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld and paid over to the appropriate Taxing Authority by US NewCo, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to LHI. US NewCo shall provide evidence of such payment to LHI to the extent that such evidence is available.

Section 7.11. Affiliated Corporations; Admission of US NewCo into a Consolidated Group; Transfers of Corporate Assets.

(a)                                 If US NewCo is or becomes a member of an affiliated or consolidated group of corporations that files a consolidated income tax return pursuant to Sections 1501 et seq. of the Code or any corresponding provision of state or local Tax law, as applicable, (other than if US NewCo becomes a member of such a group as a result of a Change of Control, in which case the provisions of Article IV shall control), then: (i) the provisions of this Agreement shall be applied with respect to the group as a whole; and (ii) Annual Tax Payments shall be computed with reference to the consolidated taxable income of the group as a whole.

(b)                                 If any Taxable Entity is or becomes a member of a Combined Taxation Group for purposes of state or foreign income Taxes (other than if a Taxable Entity becomes a member of such a group as a result of a Change of Control or Divestiture, in which cases the provisions of Article IV shall control), then: (i) the provisions of this Agreement shall be applied with respect to the group as a whole; and (ii) Annual Tax Payments shall be computed with reference to the combined taxable income of the group as a whole.

(c)                                  If any Person the income of which is included in the income of any Taxable Entity’s Combined Taxation Group transfers one or more assets to a corporation or any Person treated as such for Tax purposes the income of which is not included in such Combined Taxation Group, for purposes of calculating the amount of any Annual Tax Payment (e.g., calculating the gross income of a Taxable Entity’s Combined Taxation Group and determining the Realized Tax Benefit) due hereunder, such Person shall be treated as having disposed of such asset in a fully taxable transaction on the date of such transfer. The consideration deemed to be received by such entity shall be equal to the fair market value of the transferred asset, plus (i) the amount of debt to which such asset is subject, in the case of a transfer of an encumbered asset or (ii) the amount of debt allocated to such asset, in the case of a transfer of a partnership interest.

Section 7.12. Confidentiality. (a) LHI and each of its assignees acknowledges and agrees that the information of US NewCo is confidential and, except in the course of performing any duties as necessary for US NewCo and its Affiliates, as required by law or legal process or to enforce the terms of this Agreement, shall keep and retain in the strictest confidence and not

disclose to any Person all confidential matters of US NewCo or LHI acquired pursuant to this Agreement. This Section 7.12 shall not apply to (i) any information that has been made publicly available by US NewCo or any of its Affiliates, becomes public knowledge (except as a result of an act of LHI in violation of this Agreement) or is generally known to the business community; and (ii) the disclosure of information to the extent necessary for LHI to prepare and file its Tax returns, to respond to any inquiries regarding the same from any Taxing Authority or to prosecute or defend any action, proceeding or audit by any taxing authority with respect to such returns. Notwithstanding anything to the contrary herein, LHI (and each employee, representative or other agent of LHI) may disclose to any and all Persons, without limitation of any kind, the tax treatment and tax structure of (x) US NewCo and (y) any of its transactions, and all materials of any kind (including opinions or other tax analyses) that are provided LHI relating to such tax treatment and tax structure.

(b)                                 If LHI or any of its assignees commits a breach, or threatens to commit a breach, of any of the provisions of this Section 7.12, US NewCo shall have the right and remedy to have the provisions of this Section 7.12 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 US NewCo or any of its Subsidiaries and the accounts and funds managed by US NewCo 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 7.13. Headings. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

IN WITNESS WHEREOF, the parties have duly executed this Agreement as of the date first written above.
