The Note Purchase Agreement is not intended to provide any factual information about the Company. The Note Purchase Agreement contains representations, warranties and covenants that the Company and Oberland made to each other as of specific dates. The assertions embodied in those representations, warranties and covenants were made solely for purposes of the Note Purchase Agreement between the Company and Oberland and may be subject to important qualifications and limitations agreed to by the Company and Oberland in connection with negotiating its terms, including being qualified by confidential disclosures exchanged between the parties in connection with the execution of the Note Purchase Agreement. Moreover, the representations and warranties may be subject to a contractual standard of materiality that may be different from what may be viewed as material to investors or security holders, or may have been used for the purpose of allocating risk between the Company and Oberland rather than establishing matters as facts.

Account, including by the Issuer or any other Note Party, that do not constitute Counterparty Payments or investment income on amounts in deposit in the Collection Account, without the prior written consent of the Collateral Agent.

(b) The Issuer hereby agrees and instructs that, quarterly on each March 15, June 15, September 15 and December 15 (each, a “Payment Date”), the Collateral Agent shall direct (or in the case of an escrow arrangement, the escrow agent shall direct) the disbursement of the amounts in the Collection Account to each Noteholder that held outstanding Notes as of the close of business on the Relevant Calculation Date for such Payment Date, with any amounts paid to be applied (i) first, to accrued and unpaid interest (other than any PIK Amounts), and (ii) second, to the outstanding principal amount of the Notes (including any PIK Amounts), until such Notes and all accrued and unpaid interest thereon (including any PIK Amounts) have been paid in full.

This provision is intended to prevent the Notes from being classified as “applicable high yield discount obligations,” as defined in Section 163(i) of the Code, and shall be interpreted consistently therewith.

(c) Except as otherwise provided, any payments and other amounts owing under the Operative Documents shall be made, prior to 11:00 a.m., New York City time, on the date when due pursuant to wire instructions provided to the Issuer and the Collateral Agent by the Noteholders. Except as set forth in Section 8.5(b), each payment hereunder shall be applied (i) first, to the Expenses (allocated as reasonably determined by the Collateral Agent and, without prejudice to the Issuer’s obligations pursuant to Section 16.3, invoiced to the Issuer at least ten Business Days prior to the date of the applicable payment), (ii) second, to accrued and unpaid interest (other than PIK Amounts), (iii) third, to the Redemption Premium, if any, (iv) fourth, to the outstanding principal amount of the Notes (including any PIK Amounts), and (v) fifth, to any remaining amounts then due and payable under the Operative Documents.

(d) To the extent any Counterparty Payments include amounts that are not Royalties, the Issuer shall request that the Collateral Agent disburse, or direct the Collection Account Bank to disburse, such Counterparty Payments as directed by the Issuer upon presentation to the Collateral Agent of documentation and other evidence satisfactory to the Collateral Agent that such payments are not Royalties.

Section 8.6 Pro Rata Treatment.

(a) The purchase of Notes on each Closing Date shall be made by the Purchasers pro rata on the basis of their respective commitments. All payments on account of principal of or interest on any Notes, fees or any other Obligations owing to or for the account of any one or more Noteholders shall be apportioned ratably among the Noteholders in proportion to the amounts of such principal, interest and other Obligations owed to them respectively.

(b) If any Noteholder shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Notes or other Obligations hereunder resulting in such Noteholder’s receiving payment of a proportion of the aggregate amount of its Notes and accrued interest thereon or other such Obligations greater than its pro rata share thereof as provided herein, then the Noteholder receiving such greater proportion shall (i) notify the other Noteholders of such fact and (ii) purchase (for cash at face value) participations in the Notes and such other Obligations of the other Noteholders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Noteholders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Notes and other amounts owing them; provided that (A) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, then such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (B) the provisions of this Section 8.6(b) shall not be construed to apply to (x) any payment made by any Note Party pursuant to and in accordance with the express terms of the Operative Documents or (y) any payment obtained by a Noteholder as consideration for the assignment of or sale of a participation in any of its Notes to any assignee or participant, other than to the Parent, Issuer or any Subsidiary (as to which the provisions of this Section 8.6(b) shall apply). Each Note Party consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Noteholder acquiring a participation pursuant to the foregoing arrangements may exercise against the Noteholders rights of setoff and counterclaim with respect to such participation as fully as if such Noteholder were a direct creditor of such Note Party in the amount of such participation. If under any applicable bankruptcy, insolvency or similar law, any Noteholder receives a secured claim in lieu of a setoff to which this Section 8.6(b) applies, then such Noteholder shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Noteholders entitled under this Section 8.6(b) to share in the benefits of any recovery on such secured claim.

In the event that the Applicable Agreement Parties desire to take any of the actions described in clause (iii) of the immediately preceding sentence and have reasonably concluded that such action, if taken, would not relate in any way to, or involve directly or indirectly, the Royalties or any of the Products, the Applicable Agreement Parties shall notify the Collateral Agent at least five (5) Business Days in advance of the date upon which the Applicable Agreement Parties desire to take such action, describing the nature of the action and providing reasonable detail to enable the Collateral Agent to understand the action that is contemplated to be taken and, unless the Collateral Agent provides notice to the Applicable Agreement Parties within such five (5) Business Days period that the Collateral Agent reasonably considers the action to relate in some way to, or involve directly or indirectly, the Royalties or any of the Products, including reasonable detail as to the basis for this determination, the Applicable Agreement Parties shall not be required to obtain the Collateral Agent’s consent to such action.

(b) The Applicable Agreement Parties shall timely and fully perform and comply with each of their respective duties and obligations under the Applicable Agreements.

(c) As promptly as practicable after receiving written or oral notice from Counterparty (i) terminating any Applicable Agreement or (ii) alleging any breach of or default under any Applicable Agreement by any of the Applicable Agreement Parties, the Applicable Agreement Parties shall (A) give a written notice to the Noteholders describing in reasonable detail the relevant breach or default, if applicable, including a copy of any written notice received from Counterparty, and, in the case of any such breach or default or alleged breach or default by any of the Applicable Agreement Parties, the Applicable Agreement Parties shall consult with the Collateral Agent as to any action any of the Applicable Agreement Parties proposes to take to dispute or correct such alleged breach or default and (B), at their own cost and expense, take commercially reasonable efforts (assuming the collection and receipt of the

In connection with any such dispute, where the Applicable Agreement Parties shall employ counsel or the Collateral Agent or the Required Holders reasonably request that the Applicable Agreement Parties employ counsel, the Applicable Agreement Parties shall employ, at their own cost and expense, such counsel as is reasonably acceptable to the Required Holders (as long as such counsel is reasonably acceptable to the Applicable Agreement Parties).

(d) As promptly as practicable after becoming aware of any threatened or actual breach of or default under any Applicable Agreement by Counterparty, the Applicable Agreement Parties (i) shall consult with the Collateral Agent as to their response to such threatened or actual breach or default, including giving a written notice to the Collateral Agent and the Noteholders describing in reasonable detail the relevant breach or default and any action any of the Applicable Agreement Parties proposes to take as a possible response, together with a copy of any written notice that the Applicable Agreement Parties propose to send to Counterparty, and (ii), at their own cost and expense, use commercially reasonable efforts (assuming the collection and receipt of the Royalties is the only business of the Applicable Agreement Parties and that the Applicable Agreement Parties keep all Royalties so collected and received), including, in any event, taking such actions as reasonably requested by the Collateral Agent or the Required Holders, to enforce its rights and remedies thereunder. In connection with any such response and enforcement of rights and remedies under any of the Applicable Agreements where the Applicable Agreement Parties shall employ counsel or the Collateral Agent or the Required Holders reasonably request that the Applicable Agreement Parties employ counsel, the Applicable Agreement Parties shall employ, at their own cost and expense, such counsel as is reasonably acceptable to the Required Holders (as long as such counsel is reasonably acceptable to the Applicable Agreement Parties).

(e) […***…].

Section 9.3 Applicable Patent Rights. The Issuer shall prosecute and maintain in full force and effect all patents and pending patent applications (if any) included in the Applicable Patent Rights, except where the failure to do so would not reasonably be likely to result in a Material Adverse Effect.

Section 9.4 Audits.

(a) The Collateral Agent and the Noteholders shall have the right to audit, through an independent certified public accountant selected by the Required Holders and reasonably acceptable to the Issuer, those accounts and records of the Applicable Agreement Parties relevant to any reports referred to in Section 7.2(a)(i) as may be reasonably necessary to verify the accuracy of the amounts deposited into the Collection Account based on information included in such reports referred to in Section 7.2(a)(i) for any or all of the three calendar years

prior to the audit (provided, however, that, prior to conducting any such audit, such accounting firm shall have entered into a confidentiality agreement in form and substance reasonably satisfactory to the Applicable Agreement Parties). Such audits will occur during normal business hours and no more than once per calendar year. The Noteholders’ independent certified public accountant will keep confidential all information obtained during such audit and will report to the Noteholders only the actual amount deposited into the Collection Account based on information included in the applicable reports referred to in Section 7.2(a)(i) and the resulting discrepancy, if any, between that amount and the amounts in respect of the Royalties that should have been deposited into the Collection Account during the calendar year(s) in question and the details of any discrepancies (the “Audit Report”).

(b) The Noteholders shall be solely responsible for all the expenses of any audit, unless the Audit Report shows any discrepancy where funds deposited into the Collection Account based on information included in the applicable reports referred to in Section 7.2(a)(i) were insufficient by five percent (5%) or more than such funds should have been for any of the calendar years then being reviewed. If the Audit Report shows any such discrepancy, the Applicable Agreement Parties shall be responsible for the reasonable expenses incurred by the Noteholders for the independent certified public accountant’s services. The Applicable Agreement Parties shall otherwise also be responsible for the amounts of any discrepancy shown by the Audit Report for any of the calendar years then being reviewed between the amount of funds deposited into the Collection Account based on information included in the applicable reports referred to in Section 7.2(a)(i) and what those funds should have been. Any payment owed by the Applicable Agreement Parties to the Noteholders as a result of the audit shall be made within 10 Business Days of the receipt of the independent certified public accountant’s report by the Noteholders.

(c) To the extent the Issuer has the right to perform or cause to be performed inspections or audits under either of the Counterparty License Agreements regarding payments payable and/or paid to the Applicable Agreement Parties thereunder (each, a “License Party Audit”), the Issuer shall, at the reasonable request of the Collateral Agent or the Required Holders (such request not to be made more frequently than once every calendar year), use commercially reasonable efforts to cause a License Party Audit to be performed as promptly as practicable in accordance with the terms of the applicable Counterparty License Agreement. In conducting a License Party Audit at the request of the Required Holders, subject to the terms of the License Agreement, the Issuer shall engage a nationally recognized certified public accountant selected by the Required Holders and reasonably acceptable to the Applicable Agreement Parties. As promptly as practicable after completion of any License Party Audit (whether or not requested by the Required Holders), the Issuer shall deliver to the Noteholders an audit report summarizing the results of such License Party Audit, which may be redacted for information unrelated to the Products. In the event that the Required Holders request a License Party Audit, all of the expenses of any such License Party Audit (including, without limitation, the fees and expenses of the independent public accounting firm) that would otherwise be borne by the Issuer, pursuant to the applicable Counterparty License Agreement, shall instead be borne (as such expenses are incurred) by the Noteholders, provided that any reimbursement by Counterparty of the expenses of the License Party Audit shall belong and shall be promptly paid to the Noteholders.

THE COLLATERAL AGENT

though it were not the Collateral Agent and the terms “Purchaser,” “Noteholder,” “Purchasers” or “Noteholders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Collateral Agent hereunder in its individual capacity.

(c) Indemnity. In addition to and not in limitation of the provisions of Section 13.3(b), under no circumstances shall the Collateral Agent have any duty or obligation to take any actions hereunder, even if instructed to do so by the Required Holders, if the Collateral Agent determines, in its sole and absolute discretion, that such actions would subject it to liability or expense for which indemnity or security satisfactory to it has not been provided hereunder or otherwise or would be contrary to this Operative Documents or applicable law.

(d) Reasonable Care. Notwithstanding anything to the contrary herein, the Collateral Agent’s sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under the UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar property for its own account, and the Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which comparable secured parties accord comparable collateral.

(e) Written Instructions. The Collateral Agent may at any time solicit written confirmatory instructions, including written instructions of the Required Holders or an order of a court of competent jurisdiction, as to any action that it may be requested or required to take or that it may propose to take in the performance of any of its obligations under this Agreement or the Pledge Agreement and shall be fully justified in failing or refusing to act hereunder or under the Pledge Agreement until it shall have received such requisite instructions, and the Collateral Agent shall have no liability with respect to any action taken, suffered or omitted in reliance thereon. In the event that the Collateral Agent receives written instructions from the Required Holders that the Collateral Agent determines, in its sole and absolute discretion, to be ambiguous, inconsistent, in conflict with this Agreement or the Pledge Agreement or otherwise insufficient to direct the actions of the Collateral Agent, then the Collateral Agent shall have no obligation whatsoever to take or refrain from taking any action pursuant to such written instructions, but may (but shall not be obligated) instead do one or more of the following:

(i) seek additional written instructions satisfactory to it from the Required Holders, and the Collateral Agent shall have no liability with respect to any action taken, suffered or omitted in reliance thereon;

(ii) resign as Collateral Agent in accordance with this Agreement; or

(iii) at the expense of the Noteholders, which fees and expenses shall be paid in advance, commence an action in a court of competent jurisdiction requiring the Noteholders to interplead and settle among themselves their rights in and to the Collateral and any proceeds thereof then held by the Collateral Agent.

(ii) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Operative Documents to which it is a party that the Collateral Agent is required to exercise as directed in writing by the Required Holders (or such other number or percentage of the Noteholders as shall be expressly provided for herein or in such other Operative Documents), provided that the Collateral Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Collateral Agent to liability or that is contrary to any Operative Document or applicable law; and

(iii) shall not, except as expressly set forth herein and in the other Operative Documents to which it is a party, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to any Note Party or any of its Affiliates that is communicated to or obtained by the Person serving as the Collateral Agent or any of its Affiliates in any capacity.

(b) The Collateral Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Holders (or such other number or percentage of the Noteholders as shall be necessary, or as the Collateral Agent shall believe in good faith shall be necessary, under the circumstances as provided in Article XIV) or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and nonappealable judgment. The Collateral Agent shall be deemed not to have knowledge of any Default or Event of Default unless and until notice describing such Default or Event of Default is given to the Collateral Agent in writing by the Issuer or a Noteholder.

(c) The Collateral Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Operative Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event of Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Credit Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article VI or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Collateral Agent.

		Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Company’s application requesting confidential treatment under Rule 24b-2 of the Exchange Act; […***…] denotes omissions.

consent, statement, instrument, document or other writing (including any electronic message, internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Collateral Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. The Collateral Agent may consult with legal counsel, independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Section 13.6 Delegation of Duties. The Collateral Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Credit Document by or through any one or more sub-agents appointed by the Collateral Agent. The Collateral Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Collateral Agent and any such sub-agent. The Collateral Agent shall not be responsible for the negligence or misconduct of any sub-agent except to the extent that a court of competent jurisdiction determines in a final and nonappealable judgment that the Collateral Agent acted with gross negligence or willful misconduct in the selection of such sub-agent.

Section 13.7 Resignation of Collateral Agent. The Collateral Agent may at any time give notice of its resignation to the Noteholders and the Issuer. Upon the receipt of any such notice of resignation, the Required Holders shall have the right, in consultation with the Issuer so long as no Default has occurred and is continuing, to appoint a successor. If no successor shall have been so appointed by the Required Holders and shall have accepted such appointment within 30 days after the retiring Collateral Agent gives notice of its resignation, then the retiring Collateral Agent may, on behalf of the Noteholders, appoint a successor Collateral Agent; provided that, whether or not a successor has been appointed or has accepted such appointment, such resignation shall become effective upon delivery of the notice thereof. Upon the acceptance of a successor’s appointment as Collateral Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Collateral Agent, and the retiring Collateral Agent shall be discharged from all of its duties and obligations under the Credit Documents (if not already discharged therefrom as provided above in this Section 13.6). After the retiring Collateral Agent’s resignation, the provisions of this Article XIII and Section 16.13 shall continue in effect for the benefit of such retiring Collateral Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Collateral Agent was acting as Collateral Agent. Upon any resignation by the Collateral Agent, all payments, communications and determinations provided to be made by, to or through the Collateral Agent shall instead be made by, to or through each Noteholder directly, until such time as a Person accepts an appointment as Collateral Agent in accordance with this Section 13.6.

Section 13.8 Non-Reliance on Collateral Agent and Other Noteholders. Each Noteholder acknowledges that it has, independently and without reliance upon the Collateral


		Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Company’s application requesting confidential treatment under Rule 24b-2 of the Exchange Act; […***…] denotes omissions.

Agent or any other Noteholder or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and purchase the Notes hereunder. Each Noteholder also acknowledges that it will, independently and without reliance upon the Collateral Agent or any other Noteholder or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Credit Document or any related agreement or any document furnished hereunder or thereunder.

Section 13.9 Collateral and Guaranty Matters. Each Noteholder agrees that any action taken by the Collateral Agent or the Required Holders in accordance with the provisions of this Agreement or of the other Credit Documents, and the exercise by the Collateral Agent or Required Holders of the powers set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized and binding upon all of the Noteholders. Without limiting the generality of the foregoing, the Noteholders irrevocably authorize the Collateral Agent, at its option and in its discretion:

(c) to release any Subsidiary Guarantor from its obligations under the Guaranty to which it is a party to if such Person ceases to be a Subsidiary as a result of a transaction permitted hereunder.

In each case as specified in this Section 13.9, the Collateral Agent will (and each Noteholder irrevocably authorizes the Collateral Agent to), at the Note Party’s expense, execute and deliver to the applicable Note Party such documents as such Note Party may reasonably request (i) to evidence the release of such item of Collateral from the assignment and security interest granted under the Operative Documents, or (ii) to evidence the release of such Subsidiary Guarantor from its obligations under the Guaranty, in each case in accordance with the terms of the Operative Documents and this Section 13.9 and in form and substance reasonably acceptable to the Collateral Agent. The Collateral Agent shall deliver to the Noteholders notice of any action taken by it under this Section 13.9 as soon as reasonably practicable after the taking thereof; provided, that delivery o or failure to deliver any such notice shall not affect the Collateral Agent’s rights, powers, privileges and protections under this Article XIII.

Section 13.10 Reimbursement by Noteholders. To the extent that the Issuer for any reason fails to indefeasibly pay any Expenses or Costs required to be paid by it to the Collateral Agent (or any sub-agent thereof) or any Related Party of any of the foregoing, each Noteholder severally agrees to pay to the Collateral Agent (or any such sub-agent) or such Related Party, as the case may be, such Noteholder’s pro rata share (based upon the percentages as used in

Section 14.3 Binding Effect, Etc. Any amendment or waiver consented to as provided in this Article XIV applies equally to all Noteholders and is binding upon them and upon each future Noteholder and upon the Issuer without regard to whether such Note has been marked to indicate such amendment or waiver or whether the amendment or waiver or any provision thereof has been executed by any Noteholder. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Issuer and any Noteholder or any delay in exercising any rights under the Agreements or any Note shall operate as a waiver of any rights of any Noteholder.

ARTICLE XV

TAX MATTERS

Section 15.1 Statement to Noteholders. At such times as required by Applicable Law, the Issuer shall furnish to each Person that at any time during such calendar year was a Noteholder, a statement (such statement to be in the form of an IRS Form 1099, IRS Form 1042- S or any other means required by Applicable Law) prepared by the Issuer and containing the original issue discount paid with respect to the Notes for such calendar year or, in the event such Person was a Noteholder during only a portion of such calendar year, for the applicable portion of such calendar year, and such other items as are readily available to the Issuer and that a Noteholder shall reasonably request as necessary for the purpose of such Noteholder’s preparation of its U.S. federal income tax returns or other tax returns.

Section 15.2 Withholding. Each Noteholder shall deliver to the Issuer and the Collateral Agent (1) a properly completed IRS Form W-9 or W-8ECI, (2) a properly completed IRS Form W-8BEN or W-8BEN-E establishing an exemption from U.S. federal withholding tax pursuant to the “interest” article of an income tax treaty to which the United States is a party, (3) a properly completed IRS Form W-8BEN or W-8BEN-E together with a certificate substantially in the form of Exhibit F-1, or (4) a properly completed IRS Form W-8IMY together with the documentation described in (1), (2) or (3) for each beneficial owner (it being understood that the Noteholder may provide a certificate substantially in the form of Exhibit F-2 on behalf of each such beneficial owner). Unless otherwise required by Applicable Law, the Issuer shall treat, and shall direct Collateral Agent to treat, all interest (including PIK Amounts) paid on the Notes as eligible for the exemption from U.S. federal withholding tax under Section 871(h) of the Code or Section 881(c) of the Code with respect to payments of “portfolio interest” and, provided that a Noteholder has satisfied the certification requirements set forth in the foregoing sentence of this Section 15.2, the Issuer shall make, and shall direct the Collateral Agent to make, all payments (including interest and capitalized interest) to such Noteholder without deduction or withholding for any Taxes. If the Issuer or the Collateral Agent is required to deduct or withhold any Taxes from any such payment (including interest and capitalized interest) on the Notes to a Noteholder under Applicable Law, the Issuer shall: (a) be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Tax authority in accordance with Applicable Law (provided, however, that the Collateral Agent may take the actions set forth in this subclause (a) if the Collateral Agent is required by law to do so and the

Issuer has failed to do so) and (b) increase the sum payable by the Issuer as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section 15.2) the applicable Noteholder receives an amount equal to the sum it would have received had no such deduction or withholding been made in respect of Indemnified Taxes. The Issuer shall provide proof to the Collateral Agent and the Noteholders of any amounts withheld and remitted to any Governmental Authority after such withholding has taken place. The Issuer shall indemnify such Noteholder and the Collateral Agent, as applicable, within ten (10) days demand therefor for the full amount of any Indemnified Taxes that are payable or paid by such Noteholder or the Collateral Agent, as applicable, or required to be withheld or deducted from a payment to such Noteholder, with respect to amounts (including PIK Amounts) paid or payable on a Note, and shall indemnify the Collateral Agent for any Taxes that are payable or paid by the Collateral Agent in connection with its performance as Collateral Agent under this Agreement, in each case including any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted. A certificate as to the amount of such payment or liability delivered to the Issuer by a Noteholder or the Collateral Agent, as applicable, shall be conclusive absent manifest error.

Section 15.3 Determinations and Responsibilities. Consistent with this Article 15, the Issuer shall be the party responsible for determining and complying with the requirements of the Internal Revenue Service and applicable state and local tax laws with respect to reporting and withholding on the Noteholder, subject to the Issuer’s covenant in Section 15.2 to treat all interest (including PIK Amounts) paid on the Notes as eligible for the exemption from U.S. federal withholding tax under Section 871(h) of the Code or Section 881(c) of the Code with respect to payments of “portfolio interest”. In furtherance of the foregoing, the Issuer shall inform the Collateral Agent with respect to any and all tax withholding undertaken by the Issuer in connection with amounts held in the Collection Account and the Issuer shall timely and properly file all information returns required to be filed in respect of payments made on the Notes (including, but not limited to, IRS Form 1099 and IRS Form 1042, as applicable).

Without limiting the generality of the foregoing, each Guarantor’s liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by any other Note Party to the Collateral Agent or any Noteholder under or in respect of the Operative Documents but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving such other Note Party.

Section 16.2 Obligations Unconditional. The obligations of the Guarantors under Section 16.1 are absolute and unconditional, joint and several, irrespective of the value, genuineness, validity, regularity or enforceability of the obligations of Issuer and the other Note Parties under this Agreement (other than this Article XVI) and the other Operative Documents or any other agreement or instrument referred to herein, or any substitution, release or exchange of any other guarantee of or security for any of the Guaranteed Obligations or the Obligations, and,

Without limiting the generality of the foregoing, it is agreed that the occurrence of any one or more of the following shall not alter or impair the liability of the Guarantors hereunder, which shall remain absolute and unconditional as described above:

Agreement to purchase Additional Notes they shall not exercise any right or remedy arising by reason of any performance by them of their guarantee in Section 16.1, whether by subrogation or otherwise, against the Issuer, any Note Party or any other guarantor of any of the Obligations or any security for any of the Obligations.

Section 16.5 Remedies. The Guarantors jointly and severally agree that, as between the Guarantors, on one hand, and the Collateral Agent and the Noteholders, on the other hand, the Obligations of the Issuer under the Operative Documents may be declared to be forthwith due and payable as provided in Article XI (and shall be deemed to have become automatically due and payable in the circumstances provided in Article XI) for purposes of Section 16.1 notwithstanding any stay, injunction or other prohibition preventing such declaration (or such Obligations from becoming automatically due and payable) as against the Issuer and that, in the event of such declaration (or such Obligations being deemed to have become automatically due and payable), to the extent such Obligations (whether or not due and payable by the Issuer) constitute Guaranteed Obligations, such Obligations shall forthwith become due and payable by the Guarantors for purposes of Section 16.1.

Section 16.6 Instrument for the Payment of Money. Each Guarantor hereby acknowledges that the guarantee in this Article XV constitutes an instrument for the payment of money, and consents and agrees that the Collateral Agent and the Noteholders, at their sole option, in the event of a dispute by such Guarantor in the payment of any moneys due hereunder, shall have the right to proceed by motion for summary judgment in lieu of complaint pursuant to N.Y. Civ. Prac. L&R § 3213.

Section 16.7 Continuing Guarantee. The guarantee in this Article XVI is a continuing guarantee, and shall apply to all Guaranteed Obligations whenever arising.

The payment obligation of a Guarantor to any Excess Funding Guarantor under this Section 16.8 shall be subordinate and subject in right of payment to the prior payment in full of the obligations of such Guarantor under the other provisions of this Article XVI and such Excess Funding Guarantor shall not exercise any right or remedy with respect to such excess until payment and satisfaction in full of all of such obligations.

For purposes of this Section 16.8, (i) “Excess Funding Guarantor” means, in respect of any Guaranteed Obligations, a Guarantor that has paid an amount in excess of its Pro rata Share of such Guaranteed Obligations, (ii) “Excess Payment” means, in respect of any Guaranteed Obligations, the amount paid by an Excess Funding Guarantor in excess of its Pro rata Share of such Guaranteed Obligations and (iii) “Pro Rata Share” means, for any Guarantor, the ratio

Section 16.9 General Limitation on Guarantee Obligations. In any action or proceeding involving any provincial, territorial or state corporate law, or any state or federal bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if the obligations of any Subsidiary Guarantor under Section 16.1 would otherwise, taking into account the provisions of Section 16.8, be held or determined to be void, invalid or unenforceable, or subordinated to the claims of any other creditors, on account of the amount of its liability under Section 16.1, then, notwithstanding any other provision hereof to the contrary, the amount of such liability shall, without any further action by such Subsidiary Guarantor, the Noteholders or any other Person, be automatically limited and reduced to the highest amount that is valid and enforceable and not subordinated to the claims of other creditors as determined in such action or proceeding.

Section 16.10 Release of Subsidiary Guarantors.
