If the amount of the underpayment (exclusive of interest accrued thereon pursuant to Section 3.1(a)) is greater than the lesser of (i) [***] percent ([***]%) of the total amount actually owed for the period audited or (ii) [***] Dollars ($[***]), then the Company shall in addition (w) reimburse the Investor Representative for all reasonable costs and fees of the accounting firm related to such audit and (x) pay interest accrued on such amount of the underpayment at a rate of [***] percent ([***]%) per month from the initial due date until paid in full or, if less, the maximum interest rate permitted by Applicable Law.

-73-

LEGAL 4875-0317-8306v.49

comparable yield and a projected payment schedule under Section 1.1275-4(b) (the “Comparable Yield”). Unless the Investor Representative objects to the Comparable Yield within fifteen (15) days after receipt thereof, the Comparable Yield shall become final and binding on the Parties. If the Investor Representative objects to the Comparable Yield within fifteen (15) days of receipt, then the Parties shall cooperate in good faith to agree on a revised Comparable Yield within twenty (20) days of the Investor’s objection. The Parties intend that the provisions of the U.S. Treasury Regulation Section 1.1275-2(a)(1) would apply, subject to the exceptions in the U.S. Treasury Regulation Section 1.1275-2(a)(2), to treat any non-contingent payments on the debt instrument and the projected amount of any contingent payments as first, a payment of any accrued and any unpaid original issue discount at such time and second, a payment of principal (including for purposes of the rules applicable to “applicable high yield discount obligations”). The Parties agree not to take and to not cause or permit their Affiliates to take, any position that is inconsistent with the provisions of this Section 6.22(a) on any U.S. federal, state or local income Tax return or for any other U.S. federal, state or local income Tax purpose, unless required by Applicable Law or the good faith resolution of a Tax audit or other Tax proceeding.

(c)Payments by or on account of any obligation of any Company Party under any Transaction Document shall be made without deduction or withholding for any Taxes, except as required by Applicable Law. If any Company Party is required by Applicable Law to deduct or withhold any Tax in respect of any amounts payable to an Investor pursuant to any Transaction Document, (1) such Company Party shall make such deduction or withholding and timely pay such amount to the applicable Governmental Authority, (2) such Company Party shall provide such Investor with a receipt evidencing such payment or other evidence of such payment reasonably satisfactory to such Investor and (3) if the Tax deducted or withheld was an Indemnified Tax, the sum payable by such Company Party shall be increased so that after all required deductions and withholdings for Indemnified Taxes have been made (including deductions and withholdings applicable to additional sums payable under this Section 6.22(c)), such Investor receives an amount equal to the sum it would have received had no such deductions or withholdings been made. The Company will promptly notify an Investor if any Company Party becomes required to deduct or withhold any Tax in respect of any payment to such Investor pursuant to any Transaction Document.

(d)If the Investor determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has received Additional Amounts pursuant to this ‎Section 6.22, it shall pay to the Company an amount equal to such refund (but only to the extent of Additional Amounts paid under this ‎‎Section 6.22 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of the Investor and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). The Company, upon the request of the Investor, shall repay to the Investor the amount paid over pursuant to this Section 6.22(d) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that the Investor is required to repay such refund

-74-

LEGAL 4875-0317-8306v.49

to such Governmental Authority. Notwithstanding anything to the contrary in this Section 6.22(d), in no event will the Investor be required to pay any amount to the Company pursuant to this Section 6.22(d) the payment of which would place the Investor in a less favorable net after-Tax position than the Investor would have been in if the Tax for which the Company paid Additional Amounts and giving rise to such refund had not been deducted, withheld or otherwise imposed and the Additional Amounts with respect to such Tax had never been paid. This Section 6.22(d) shall not be construed to require the Investor to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the Company or any other Person other than a reasonably detailed explanation of any computation made pursuant to this Section 6.22(d).

(e)The Company shall timely pay to the applicable Governmental Authority in accordance with Applicable Law any Other Taxes.

(f)Without duplication of any amounts payable under Section 6.22(c) or Section 6.22(e), the Company shall indemnify the Investor with respect to any Indemnified Tax or Other Tax payable or paid by the Investor (including any Indemnified Tax or Other Tax payable or paid with respect to any amounts payable under this Section 6.22) and any reasonable expenses related thereto, in each case whether or not such Taxes were correctly or legally asserted by the applicable Governmental Authority. Any such indemnification shall be paid within fifteen (15) days after the Investor makes a written demand therefor. A certificate as to the amount of such payment or liability, accompanied by a reasonable explanation thereof, delivered to the Company by the Investor shall be conclusive absent manifest error.

(g)Each Party’s obligations under this Section 6.22 shall survive the termination of this Agreement, any assignment by an Investor and the repayment, satisfaction or discharge of all obligations under this Agreement.

The indemnifying party shall not be liable for any settlement of any Third Party Claim effected without its written consent, but, if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any Loss by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or discharge of any pending or threatened Third Party Claim in respect of which any indemnified party is or would have been a party and indemnity would have been sought hereunder by such indemnified party, unless such settlement, compromise or discharge, as the case may be, (i) includes an unconditional written release of such indemnified party, in form and substance reasonably satisfactory to the indemnified party, from all liability on claims that are the subject matter of such claim or proceeding, (ii) does not include any statement as to an admission of fault,

-91-

LEGAL 4875-0317-8306v.49

culpability or failure to act by or on behalf of any indemnified party and (iii) does not impose any continuing material obligation or restrictions on such indemnified party.

Section 10.4 Other Claims. A claim by an indemnified party under this ‎ARTICLE X for any matter not involving a Third Party Claim and in respect of which such indemnified party seeks indemnification hereunder may be made by delivering, in good faith, a written notice of demand to the indemnifying party, which notice shall contain (a) a description and the amount of any Losses incurred or suffered by the indemnified party (and the method of computation of such Losses), (b) a statement that the indemnified party is entitled to indemnification under this ‎ARTICLE X for such Losses and a reasonable explanation of the basis therefor, and (c) a demand for payment in the amount of such Losses. For all purposes of this Section 10.4, the Company shall be entitled to deliver such notice of demand to the Investor Representative on behalf of the Company Indemnified Parties, and the Investor Representative shall be entitled to deliver such notice of demand to the Company on behalf of the Investor Indemnified Parties. Within thirty (30) days after receipt by the indemnifying party of any such notice, the indemnifying party may deliver to the indemnified party that delivered the notice a written response in which the indemnifying party (a) agrees that the indemnified party is entitled to the full amount of the Losses claimed in the notice from the indemnified party; (b) agrees that the indemnified party is entitled to part, but not all, of the amount of the Losses claimed in the notice from the indemnified party; or (c) indicates that the indemnifying party disputes the entire amount of the Losses claimed in the notice from the indemnified party. If the indemnified party does not receive such a response from the indemnifying party within such thirty (30)-day period, then the indemnifying party shall be conclusively deemed to have agreed that the indemnified party is entitled to the full amount. If the indemnifying party and the indemnified party are unable to resolve any Dispute relating to any amount of the Losses claimed in the notice from the indemnified party within thirty (30) days after the delivery of the response to such notice from the indemnifying party, then the parties shall be entitled to resort to any legal remedy available to such party to resolve such Dispute that is provided for in this Agreement, subject to all the terms, conditions and limitations of this Agreement.

Section 10.5 Exclusive Remedies. The indemnification afforded by this ‎ARTICLE X shall be the sole and exclusive remedy for any and all Losses awarded against or incurred or suffered by the Investor Indemnified Parties against the Company in connection with the Company Indemnification Obligations and the Company Indemnified Parties against the Investor in connection with the Investor Indemnification Obligations under Section 10.1 or Section 10.2, as applicable, in each case other than any Company Indemnification Obligations or Investor Indemnification Obligations, as applicable, resulting from (a) the fraud, bad faith or willful misconduct of the other Party or (b) acts or omissions based upon the written instructions from the other Party; provided that nothing in this Section 10.5 shall alter or affect the rights of the either Party to specific performance by the other Party under the Transaction Documents or the rights of the Investor to exercise remedies under the Transaction Documents after an Event of Default or other rights of creditors under the UCC or any other Applicable Law.

Section 10.6Certain Limitations. The indemnification afforded by this ‎ARTICLE X shall be subject to the following limitations:

-92-

LEGAL 4875-0317-8306v.49

(a)With respect to indemnification by the Company pursuant to Section 10.1(a), the Company’s maximum liability for any Loss suffered by an Investor Indemnified Party (other than any Loss resulting from a Third Party Claim) shall not exceed an amount (the “Company Indemnification Cap”) equal to:

(ii)the aggregate amount of all of the payments (including any amounts received by the Investor pursuant to the Insurance Policy, if any) collected or received by the Investor Representative (and any direct or indirect transferee of the Investor Representative to whom any interest in the Revenue Interests is transferred) hereunder as of such date of determination (other than (A) any payments collected or received as a reimbursement of expenses incurred by any Investor Indemnified Party (including attorney’s fees) and (B) any indemnification payments collected or received pursuant to Section 10.1(a)), minus

(iii)the aggregate amount collected or received by the Investor Representative (and any direct or indirect transferee of the Investor Representative to whom any interest in the Revenue Interests is transferred) pursuant to the exercise of its rights under Section 10.1(a) (without duplication of any amounts collected or received pursuant to clause (ii)) prior to such date of determination to the extent such amount was not collected or received in connection with a Third Party Claim.

Notwithstanding the foregoing, the Company Indemnification Cap shall not apply to any Loss suffered by any Investor Indemnified Party in connection with a Third Party Claim.

(b)With respect to indemnification by the Investor pursuant to Section 10.2, the Investor’s maximum liability shall not exceed an amount equal to the excess (if any) of (a) the aggregate amount of all of the payments collected or received by the Investor from the Company prior to the date of determination (excluding any amounts collected or received as a reimbursement of expenses incurred by the Investor or any indemnification amounts collected or received in connection with a Third Party Claim) over (b) the Investment Amount.
