GUARANTY

THIS GUARANTY (as amended, restated, supplemented or otherwise modified from time to time, this “Guaranty”), dated as of March 3, 2017, is made by (i) REGENERON PHARMACEUTICALS, INC., a New York corporation (the “Parent Guarantor”), (ii) each of the undersigned Subsidiaries (as hereinafter defined) of the Parent Guarantor (the “Initial Subsidiary Guarantors” and together with Parent Guarantor, the “Initial Guarantors”) and (iii) any additional Subsidiaries of the Parent Guarantor which become parties to this Guaranty by executing a supplement hereto in the form attached as Annex I (collectively with the Initial Subsidiary Guarantors, the “Subsidiary Guarantors” and together with Parent Guarantor, the “Guarantors”) in favor of (a) each Participant (as hereinafter defined) and (b) the Administrative Agent (as hereinafter defined), for the benefit of itself and the other Beneficiaries (as hereinafter defined).

W I T N E S S E T H:

WHEREAS, Old Saw Mill Holdings LLC, a New York limited liability company, as Lessee (together with its successors and permitted assigns, in its capacity as Lessee, “Lessee”), BA Leasing BSC LLC, a Delaware limited liability company, as Lessor (together with its successors and permitted assigns, in its capacity as Lessor, “Lessor”), the Lenders party thereto and Bank of America, N.A., not in its individual capacity, except as expressly stated therein, but solely as Administrative Agent (together with its successors and permitted assigns, in its capacity as Administrative Agent, the “Administrative Agent”) have entered into that certain Participation Agreement, dated as of March 3, 2017 (as amended, restated, supplemented or otherwise modified from time to time, the “Participation Agreement”; unless otherwise defined herein or the context hereof otherwise requires, terms which are defined or defined by reference in the Participation Agreement shall have the same meanings when used herein as such terms have therein); and

WHEREAS, it is a condition precedent to the consummation by the Participants (as hereinafter defined) of the Overall Transaction to be consummated on the Document Closing Date that the Initial Guarantors execute and deliver this Guaranty; and

WHEREAS, each Subsidiary Guarantor is an affiliate of Lessee, and Lessee and each Subsidiary Guarantor is a direct or indirect wholly-owned Subsidiary of Parent Guarantor and it is in the best interests of Parent Guarantor and each Subsidiary Guarantor that the Overall Transaction and the Document Closing Date occur;

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged by each Guarantor, each Guarantor hereby agrees as follows:

Section 1. Guarantee. Each Guarantor, jointly and severally, hereby irrevocably and unconditionally guarantees to (i) each Participant, for the benefit of itself and its Related Parties that are Beneficiaries (as hereinafter defined), and (ii) the Administrative Agent, for the benefit of itself and the other Beneficiaries (a) the full and prompt payment when due, whether by

acceleration or otherwise, and at all times thereafter, and (b) the full and prompt performance when due of all of the Liabilities (as hereinafter defined) (or, in the case of such guarantee to each Participant, all of the Liabilities owed to such Participant and its Related Parties that are Beneficiaries), including, interest or yield on any such Liabilities, whether accruing before or after any bankruptcy or insolvency case or proceeding involving Lessee or any other Person, and, if interest or yield on any portion of such obligations ceases to accrue by operation of law by reason of the commencement of such case or proceeding, including such interest and yield as would have accrued on any such portion of such obligations if such case or proceeding had not commenced. Each Guarantor further agrees to pay all expenses (including reasonable attorneys’ fees actually incurred and legal expenses) paid or incurred by any Beneficiary in endeavoring to collect the Liabilities, or any part thereof, and in enforcing this Guaranty, subject to the limitations set forth in Section 15.17 of the Participation Agreement (including with respect to attorneys’ fees). The term “Beneficiaries,” as used herein, shall mean each of Lessor, Administrative Agent, each other Participant and each other Indemnitee. The term “Liabilities,” as used herein, shall mean all of the following, in each case howsoever created, arising or evidenced, whether direct or indirect, joint or several, absolute or contingent, or now or hereafter existing, or due or to become due: all Rent (including, but not limited to Basic Rent and Supplemental Rent), Lease Balance, Purchase Amount, Sale Option Recourse Amount, indemnities and all additional amounts and other sums at any time due and owing, and required to be paid, in each case of the foregoing, by Lessee under the terms of the Lease, the Participation Agreement or any other Operative Document and all other obligations, covenants and agreements to be performed by Lessee under the Lease, the Participation Agreement or any other Operative Document (whether or not Lessee, any Guarantor or any other Person shall be relieved or released from any or all liability or obligations under any thereof, except on account of the full and indefeasible payment and performance of all Liabilities).

In any action or proceeding involving any state corporate law, or any state or federal bankruptcy, insolvency, reorganization or any other law affecting the rights of creditors generally, if the obligations of any Guarantor under this Guaranty would otherwise 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 this Guaranty, then, notwithstanding any other provision hereof to the contrary, the amount of such liability shall, without any further action by such Guarantor or any other Person, be automatically limited and reduced to the highest amount which is valid and enforceable as determined in such action or proceeding.

Each Guarantor agrees that upon the occurrence of an Event of Default described in Section 16.1(h) or (i) of the Lease, the Guarantors will pay to the Administrative Agent, for the benefit of the Beneficiaries, forthwith the full amount which would be payable hereunder by the Guarantors as if all Liabilities were then due and payable.

This Guaranty shall in all respects be an absolute and unconditional guaranty of payment and performance (and not of collection), and shall remain in full force and effect until the full and indefeasible payment and performance of all of the Liabilities and Guarantors’ obligations hereunder (notwithstanding, without limitation, the dissolution of Guarantors). The liability of Guarantors hereunder may be enforced without the Beneficiaries being required to resort to any other right, remedy or security; provided that any such enforcement shall be subject to any

applicable grace or notice and cure period and shall be in accordance with Section 5.2 of the Loan Agreement and 16.2 of the Lease; provided, further, that, if an Acceleration has not occurred and a Payment Default exists under clause (ii) of such definition with respect to amounts owed to any Participant or its Related Parties that are Beneficiaries (other than a Payment Default with respect to (x) Basic Rent or (y) amounts owed to all Lenders or all Participants), then such Participant may demand payment hereunder for such amounts.

The obligations of Guarantor are independent of any obligations of Lessor, Administrative Agent, any Participant or any other Person under any of the Operative Documents. Each and every Event of Default under any of the Operative Documents with respect to the Liabilities shall give rise to a separate claim and cause of action hereunder, and separate claims or suits may be made and brought, as the case may be, hereunder as each such Event of Default occurs (subject to the provisos at the end of the immediately preceding paragraph).

Lessor and/or Administrative Agent on behalf of itself and the Beneficiaries may, from time to time at its discretion and without notice to any Guarantor, but subject to the provisions of the Operative Documents, take any or all of the following actions: (a) retain or obtain a lien upon or a security interest in any property to secure any of the Liabilities or any obligation hereunder; (b) retain or obtain the primary or secondary obligation of any obligor or obligors, in addition to the Guarantors, with respect to any of the Liabilities; (c) extend or renew for one or more periods (regardless of whether longer than the original period), alter or exchange any of the Liabilities, or release or compromise any obligation of any Guarantor hereunder or any obligation of any nature of any other obligor with respect to any of the Liabilities (including, without limitation, Lessee); (d) release or fail to perfect its lien upon or security interest in, or impair, surrender, release or permit any substitution or exchange for, all or any part of any property securing any of the Liabilities or any obligation hereunder, or extend or renew for one or more periods (regardless of whether longer than the original period) or release, compromise, alter or exchange any obligations of any nature of any obligor with respect to any such property; and (e) resort to any Guarantor for payment of any of the Liabilities, regardless of whether Lessor, any Lender or any other Person shall have resorted to any property securing any of the Liabilities or any obligation hereunder or shall have proceeded against any other obligor primarily or secondarily obligated with respect to any of the Liabilities (all of the actions referred to in this paragraph being hereby expressly waived by each Guarantor).

Notwithstanding anything to the contrary herein, amounts paid or collected under this Guaranty shall be subject to Section 5.3 of the Participation Agreement, except to the extent otherwise expressly provided in any other applicable provision of the Participation Agreement.

Section 2. Guarantor’s Obligations Unconditional. Guarantors’ obligations hereunder are independent of Lessee’s obligations under the Lease and the other Operative Documents or in respect of any other Person, and the Administrative Agent, for the benefit of the Beneficiaries, may enforce any of its rights hereunder independently of any other right or remedy that it or any other Beneficiary may at any time hold with respect to the Liabilities or any security or other guaranty therefor. Such obligations shall be absolute and unconditional, shall not be subject to any counterclaim, setoff, deduction (other than deductions or withholdings in respect of Taxes

that are permitted by the Operative Documents), diminution, abatement, recoupment, suspension, deferment, reduction or defense (other than full and indefeasible payment and performance of all of the Liabilities), whether based upon any claim that Lessee, Guarantor or any other Person may have against any Beneficiary or any other Person or otherwise, and shall remain in full force and effect without regard to, and shall not be released, discharged or in any way affected by, any circumstance or condition whatsoever (other than full and indefeasible payment and performance of all of the Liabilities or as otherwise expressly permitted by Section 17) (whether or not any Guarantor or any other Person shall have any knowledge or notice thereof) including, without limitation, any of the following:

(A) subject to the terms of the Lease and the other Operative Documents, any amendment, modification, addition, deletion, supplement or renewal to or of or other change in the Liabilities or any Operative Document or any of the agreements referred to in any thereof, or any other instrument or agreement applicable to any Operative Document or any of the parties to such agreements, or to the Leased Property, or any assignment, mortgage or transfer thereof or of any interest therein, or any furnishing or acceptance of additional security for, guaranty of or right of offset with respect to, any of the Liabilities; or the failure of any security or the failure of any Beneficiary to perfect or insure any interest in any collateral;

(B) any failure, omission or delay on the part of Lessee, any Beneficiary or any other Guarantor to conform or comply with any term of any instrument or agreement referred to in clause (A) above;

(C) any waiver, consent, extension, indulgence, compromise, release or other action or inaction under or in respect of any instrument, agreement, guaranty, right of offset or security referred to in clause (A) above or any obligation or liability of Lessee or any Beneficiary or any other Person, or any exercise or non-exercise by any Beneficiary or any other Person of any right, remedy, power or privilege under or in respect of any such instrument, agreement, guaranty, right of offset or security or any such obligation or liability;

(D) any bankruptcy, insolvency, reorganization, arrangement, readjustment, composition, liquidation or similar proceeding with respect to Lessee, any Beneficiary, any Guarantor or any other guarantor or obligor of any Liabilities or any of their respective properties, or any action taken by any trustee, receiver or court in any such proceeding;

(E) subject to Sections 15.15 and 15.16 of the Participation Agreement, any limitation on the liability or obligations of any Person (including, without limitation, Lessee) under any Operative Document, the Liabilities, any collateral security for the Liabilities, any other guaranty of the Liabilities or any discharge, termination, cancellation, frustration, irregularity, invalidity or unenforceability, in whole or in part, of any of the foregoing or any other agreement, instrument, guaranty or security referred to in clause (A) above or any term of any thereof (other than any such discharge, termination

or cancellation as a result of full and indefeasible payment and performance of all of the Liabilities);

(F) any defect in the title, compliance with specifications, condition, design, operation or fitness for use of, or any damage to or loss or destruction of, or any interruption or cessation in the use of the Leased Property by Lessee or any other Person for any reason whatsoever (including, without limitation, any governmental prohibition or restriction, condemnation, requisition, seizure or any other act on the part of any governmental or military authority, or any act of God or of the public enemy) regardless of the duration thereof (even though such duration would otherwise constitute a frustration of a lease), whether or not resulting from accident and whether or not without fault on the part of Lessee or any other Person;

(G) any merger or consolidation of Lessee or any Guarantor into or with any other Person, or any sale, lease or transfer of any of the assets of Lessee or any Guarantor to any other Person, except as otherwise expressly provided by Section 17;

(H) any change in the ownership of any shares of capital stock of Lessee or any Guarantor or any corporate change in Lessee or any Guarantor, except as otherwise expressly provided by Section 17;

(I) any recovery of judgment against Lessee, or by any levy of any writ or process of execution under any such judgment (except to the extent such recovery indefeasibly reduces the Liabilities);

(J) any legal characterization of the obligations created by the Lease and the other Operative Documents as a lease, a secured financing or otherwise;

(K) absence of any notice to, or knowledge of, Guarantors of the existence or occurrence of any of the foregoing clauses (A) through (J); or

(L) any other occurrence or circumstance whatsoever, whether similar or dissimilar to the foregoing, and any other circumstance that might otherwise constitute a legal or equitable defense or discharge of the liabilities of a guarantor or surety or that might otherwise limit recourse against the Guarantors (other than full and indefeasible payment and performance of all of the Liabilities or as otherwise expressly permitted by Section 17).

The obligations of the Guarantors set forth herein constitute the full recourse obligations of the Guarantors enforceable against them on a joint and several basis to the full extent of all their respective assets and properties, notwithstanding any provision in the Lease or any other Operative Documents.

Each Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Liabilities and notice of or proof of reliance by any Beneficiary upon this Guaranty or acceptance of this Guaranty, and the Liabilities, and any of them, shall conclusively be deemed to

have been created, contracted or incurred in reliance upon this Guaranty; provided that the foregoing shall not constitute a waiver of any notice specifically required to be given to such Guarantor by any Beneficiary under any of the Operative Documents. Each Guarantor unconditionally waives, to the extent permitted by law: (a) acceptance of this Guaranty and proof of reliance by any Beneficiary hereon; (b) notice of any of the matters referred to in clauses (A) through (L) above (other than any notice specifically required to be given to such Guarantor by any Beneficiary under any of the Operative Documents), or any right to consent or assent to any thereof (except to the extent the consent of such Guarantor with respect thereto is specifically required under any of the Operative Documents); (c) all notices that may be required by statute, rule of law or otherwise, now or hereafter in effect, to preserve intact any rights against Guarantor, including, without limitation, any demand, presentment, protest, proof or notice of nonpayment under any Operative Document, and notice of default or any failure on the part of Lessee to perform and comply with any covenant, agreement, term or condition of any Operative Document (in any such case, other than any notice specifically required to be given to such Guarantor by any Beneficiary under any of the Operative Documents); (d) any right to the enforcement, assertion or exercise against Lessee of any right, power, privilege or remedy conferred in any Operative Document or otherwise; (e) any requirement of diligence on the part of any Person; (f) any requirement of any Beneficiary to take any action whatsoever, to exhaust any remedies or to mitigate the damages resulting from a default by any Person under any Operative Document; (g) any notice of any sale, transfer or other disposition by any Person of any right under, title to or interest in any Operative Document or the Leased Property; and (h) any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge, release or defense of a guarantor or surety, or that might otherwise limit recourse against any Guarantor (other than full and indefeasible payment and performance of all of the Liabilities or as otherwise expressly permitted by Section 17).

Each Guarantor agrees that this Guaranty shall be automatically reinstated if and to the extent that for any reason any payment under any Operative Document by or on behalf of itself or Lessee is rescinded or must be otherwise disgorged or restored by any Beneficiary whether as a result of any proceedings in bankruptcy or reorganization or otherwise.

Each Guarantor further agrees that, without limiting the generality of this Guaranty, if an Event of Default shall have occurred and be continuing and any Beneficiary is prevented by Applicable Law from exercising its remedies under the Operative Documents, the Administrative Agent shall be entitled to receive hereunder from Guarantors, upon demand therefor, the sums which would have otherwise been due from Lessee to any such Beneficiary had such remedies been exercised.

Notwithstanding anything to the contrary herein, nothing contained in this Section 2 shall (i) prevent the assertion by any Guarantor or Lessee of any claim such Person may have against any Beneficiary by separate suit or proceedings or by compulsory counterclaim or (ii) constitute a waiver of any such claim, including, without limitation, any such claim arising from any breach or non-compliance by any Beneficiary of any Operative Document or any term of any instrument or agreement referred to in clause (A) of the first paragraph of this Section 2.

Section 3. Subordination of Subrogation. Until full and indefeasible payment and performance of all of the Liabilities or the termination of this Guaranty pursuant to Section 17(d), no Guarantor will exercise any rights with respect to any claim or other rights which it may now or hereafter acquire against Lessee arising from the existence, payment, performance or enforcement of such Guarantor’s obligations under this Guaranty or any other Operative Document, including any right of subrogation, reimbursement, contribution, exoneration, or indemnification, any right to participate in any claim or remedy of any Beneficiary against Lessee or any property or assets now or hereafter constituting part of the Collateral, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including the right to take or receive from Lessee directly or indirectly, in cash or other property or by setoff or in any manner, payment or security on account of such claim or other rights (other than to file proofs of claims only if the obligation owing to each Beneficiary hereunder has been fully satisfied). If any amount shall be paid to any Guarantor in violation of the preceding sentence and the Liabilities shall not have been indefeasibly paid in cash or this Guaranty terminated pursuant to Section 17(d), such amount shall be deemed to have been paid to such Guarantor for the benefit of, and held in trust for, the Administrative Agent, for the benefit of the Beneficiaries, and shall forthwith be paid to the Administrative Agent to be credited and applied pursuant to the terms of the Operative Documents. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Operative Documents and that the waiver set forth in this paragraph is knowingly made in contemplation of such benefits.

Each Guarantor hereby absolutely, unconditionally and irrevocably waives and agrees not to assert or take advantage of any defense based upon an election of remedies by any Beneficiary, including an election to proceed by nonjudicial rather than judicial foreclosure, which destroys or impairs any right of subrogation of such Guarantor or the right of such Guarantor to proceed against any Person for reimbursement, or both.

If all the Liabilities shall be paid indefeasibly in full or performed, Lessee, Lessor, Administrative Agent and/or the Lenders, as the case may be, will, at Guarantors’ request and expense, execute and deliver to Guarantors appropriate documents, without recourse and without warranty or representation, necessary to evidence the transfer by subrogation to Guarantors of an interest in the Liabilities resulting from such payment by Guarantors.

Section 4. Reasonableness and Effect of Waivers. Each Guarantor warrants and agrees that each of the waivers set forth in this Guaranty is made with full knowledge of its significance and consequences and that, under the circumstances, the waivers are reasonable and not contrary to public policy or law. If any of such waivers are determined to be contrary to any Applicable Law or public policy, such waivers shall be effective only to the maximum extent permitted by law.

Section 5. Transfers by Beneficiaries. Each Beneficiary may, from time to time, whether before or after any discontinuance of this Guaranty, at its sole discretion and without notice to Guarantors, assign or transfer any or all of its portion of the Liabilities or any interest therein in accordance with the terms and conditions of the Operative Documents; and, notwithstanding any such assignment or transfer or any subsequent assignment or transfer thereof, such Liabilities shall be and remain Liabilities for the purposes of this Guaranty, and

each and every immediate and successive permitted assignee or transferee of any of the Liabilities or of any interest therein shall, to the extent of such assignee’s or transferee’s interest in the Liabilities, be entitled to the benefits of this Guaranty to the same extent as if such assignee or transferee were such Beneficiary.

Section 6. No Waiver by Beneficiaries. No delay in the exercise of any right or remedy shall operate as a waiver thereof, and no single or partial exercise of any right or remedy shall preclude other or further exercise thereof or the exercise of any other right or remedy. The rights and remedies provided in this Guaranty shall be cumulative and not exclusive of any rights or remedies provided by Applicable Law. Each Guarantor hereby acknowledges that there are no conditions to the effectiveness of this Guaranty, other than the occurrence of the Document Closing Date.

Section 7. Guarantor Representations and Warranties. Parent Guarantor, on behalf of itself and its Subsidiaries, and as applicable, each Subsidiary Guarantor (as to itself), represents and warrants to the Administrative Agent and each of the Participants as of the Document Closing Date, other than with respect to Disclosed Matters, that:

(a) Organization; Powers; Subsidiaries. Each Guarantor and its Material Subsidiaries is duly organized or incorporated, as the case may be, validly existing and in good standing (to the extent the concept is applicable in such jurisdiction) under the laws of the jurisdiction of its organization, has all requisite organizational power and authority to carry on its business as now conducted and, except where the failure to do so could not reasonably be expected to result in a Material Adverse Effect, is qualified to do business in, and (to the extent the concept is applicable in such jurisdiction) is in good standing in, every jurisdiction where its ownership, lease or operation of properties or the conduct of its business requires such qualification. Schedule 7(a) hereto identifies each Subsidiary as of the Document Closing Date, noting whether such Subsidiary is a Material Domestic Subsidiary and/or a Material Subsidiary as of the Document Closing Date, the jurisdiction of its incorporation or organization, as the case may be, the percentage of issued and outstanding shares of each class of its capital stock or other equity interests owned by the Parent Guarantor and the other Subsidiaries and, if such percentage is not 100% (excluding (i) directors’ qualifying shares and (ii) shares issued to foreign nationals to the extent required by applicable law), a description of each class issued and outstanding. All of the outstanding shares of capital stock and other equity interests of the Lessee and each Material Subsidiary are validly issued and outstanding and fully paid and nonassessable and all such shares and other equity interests indicated on Schedule 7(a) as owned by the Parent Guarantor or another Subsidiary are owned, beneficially and of record, by the Parent Guarantor or any Subsidiary free and clear of all Liens, other than Liens permitted pursuant to Section 9(b). Except for Disclosed Matters or as set forth on Schedule 7(a), as of the Document Closing Date, there are no outstanding commitments or other obligations of the Parent Guarantor, Lessee or any Material Subsidiary to issue, and no options, warrants or other rights of any Person to acquire, any shares of any class of capital stock or other equity interests of Lessee or any Material Subsidiary.

(b) Authorization; Enforceability. The Operative Documents are within each Guarantor’s organizational powers and have been duly authorized by all necessary organizational

actions and, if required, actions by equity holders. The Operative Documents to which any Guarantor is a party have been duly executed and delivered by such Guarantor and constitute a legal, valid and binding obligation of such Guarantor, enforceable in accordance with its terms, subject to (i) applicable bankruptcy, insolvency, examinership, reorganization, moratorium or other laws affecting creditors’ rights generally, (ii) general principles of equity, regardless of whether considered in a proceeding in equity or at law and (iii) requirements of reasonableness, good faith and fair dealing.

(c) Governmental Approvals; No Conflicts. The execution, delivery and performance by each Guarantor of the Operative Documents to which such Guarantor is a party (i) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except such as have been, or will be by the time required, obtained or made and are, or will be by the time required, in full force and effect, (ii) will not violate in any material respect any applicable material law or regulation or the charter, by-laws or other organizational documents of such Guarantor or any material order of any Governmental Authority binding upon any Guarantor or its assets, (iii) will not violate in any material respect or result in a default under any indenture, material agreement or other material instrument binding upon such Guarantor or any of its Material Subsidiaries or its assets, or give rise to a right thereunder to require any payment to be made by any Guarantor or any of its Material Subsidiaries, except, in the case of this clause (iii), for any such violations, defaults or rights that could not reasonably be expected to result in a Material Adverse Effect, and (iv) will not result in the creation or imposition of any Lien on any asset of such Guarantor or any of its Material Subsidiaries, other than Permitted Liens and requirements (if any) to provide cash collateral or deposits under any of the Operative Documents.

(d) Financial Condition; No Material Adverse Change. (i) The Parent Guarantor has heretofore furnished to the Participants its consolidated balance sheet and statements of operations, stockholders equity and cash flows as of and for the fiscal quarter ended September 30, 2016. Such financial statements present fairly, in all material respects, the financial position and results of operations and cash flows of the Parent Guarantor and its consolidated Subsidiaries as of such dates and for such periods in accordance with GAAP, subject to normal year-end audit adjustments and the absence of footnotes.

(ii) As of the Document Closing Date and excluding any Disclosed Matters, since September 30, 2016, there has been no material adverse change in the business, assets, operations or financial condition of the Parent Guarantor and its Subsidiaries, taken as a whole.

(e) Properties. (i) Except for Liens permitted pursuant to Section 9(b), each of the Parent Guarantor and its Subsidiaries (including the Lessee) has good title to, or (to the knowledge of the Parent Guarantor) valid leasehold interests in, all its real and personal property (other than intellectual property, which is subject to Section 7(e)(ii)) material to its business, except as could not reasonably be expected to result in a Material Adverse Effect.

(ii) Except for Disclosed Matters or as could not reasonably be expected to result in a Material Adverse Effect, (A) each of the Parent Guarantor and its Subsidiaries

(including the Lessee) owns or is licensed to use (subject to the knowledge-qualified infringement representation in this Section 7(e)) all trademarks, trade names, copyrights, patents and other intellectual property material to its business, and (B) the use thereof by the Parent Guarantor and its Subsidiaries (including the Lessee), to the Parent Guarantor’s knowledge, does not infringe upon the rights of any other Person.

(f) Litigation; Environmental Matters. (i) As of the Document Closing Date and except for Disclosed Matters, there are no actions, suits, proceedings or investigations by or before any arbitrator or Governmental Authority pending against or, to the knowledge of the Parent Guarantor, threatened in writing against or affecting the Parent Guarantor or any of its Subsidiaries (including the Lessee) (A) that could reasonably be expected to result in a Material Adverse Effect or (B) that involve this Guaranty, the Operative Documents or the Overall Transaction.

(ii) Except with respect to Disclosed Matters and other matters that could not reasonably be expected to result in a Material Adverse Effect (and other than with respect to the Site or Leased Property, which is subject to Section 7(p)), the Parent Guarantor and its Subsidiaries (including the Lessee) (A) are in compliance with all applicable Environmental Laws (which compliance includes possession of and compliance with all permits, licenses or other approvals required under applicable Environmental Laws), (B) are not subject to any Environmental Liability or (C) have not received written notice of any claim with respect to any Environmental Liability.

(g) Compliance with Laws. Each of the Parent Guarantor and its Subsidiaries (including the Lessee) is in compliance with all laws, regulations and orders of any Governmental Authority applicable to it or its property, except (i) for Disclosed Matters or (ii) where the failure to do so could not reasonably be expected to result in a Material Adverse Effect.

(h) Investment Company Status. Neither the Parent Guarantor nor any of its Subsidiaries (including the Lessee) is required to be registered as an “investment company” as defined in the Investment Company Act or subject to regulation as an “investment company” thereunder.

(i) Taxes. Each of the Parent Guarantor and its Subsidiaries (including the Lessee) has timely filed or caused to be filed all federal income Tax returns and all other material Tax returns and reports required to have been filed by it and has paid, caused to be paid or made a provision for the payment of, all federal income Taxes and all other material Taxes required to have been paid by it, except (A) Taxes that are being contested in good faith by appropriate proceedings and for which the Parent Guarantor and/or such Subsidiary, as applicable, has set aside on its books adequate reserves in accordance with GAAP or (B) to the extent that the failure to do so could not reasonably be expected to result in a Material Adverse Effect.

(j) ERISA. No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, could reasonably be expected to result in a Material Adverse Effect.

(k) Disclosure. All written information (including the information set forth in the Information Memorandum) and all information that is formally presented at a general meeting (which may be a telephonic meeting) of the Lenders, other than any projections, estimates, forecasts and other forward-looking information and information of a general economic or industry-specific nature furnished by or on behalf of the Parent Guarantor or any Subsidiary to the Lessor or Administrative Agent or any other Participant pursuant to or in connection with this Guaranty or any other Operative Document, when taken as a whole and after giving effect to all supplements and updates thereto, does not (when furnished) contain any untrue statement of material fact or omit to state a material fact necessary in order to make the statements contained therein not materially misleading (when taken as a whole) in light of the circumstances under which such statements are made; provided that, with respect to forecasts or projections, each Guarantor represents only that such information was prepared in good faith based upon assumptions believed by the Parent Guarantor to be reasonable at the time prepared (it being understood by the Lessor, the Administrative Agent and the other Participants that any such projections are not to be viewed as facts and are subject to significant uncertainties and contingencies, many of which are beyond the control of the Parent Guarantor, the Lessee or their respective Subsidiaries, that no assurances can be given that such projections will be realized and that actual results may differ materially from such projections).

(l) Federal Reserve Regulations. No part of the proceeds of the Advance have been used or will be used, whether directly or indirectly, for any purpose that entails a violation of any of the Regulations of the F.R.S. Board, including Regulations T, U and X of the F.R.S. Board.

(m) No Default. As of the Document Closing Date, no Default, Event of Default, Event of Loss, Specified Significant Environmental Event or Specified Material Environmental Violation has occurred and is continuing.

To the fullest extent permitted by law, each Guarantor hereby waives and releases any claims that it may have against the Administrative Agent, or any Participant with respect to any breach or alleged breach of agency or fiduciary duty in connection with any aspect of any transaction contemplated hereby.

Section 17. Releases; Termination of Guaranty.

(a) A Subsidiary Guarantor shall automatically be released from its obligations under this Guaranty upon the consummation of any transaction permitted by this Guaranty as a result of which such Subsidiary Guarantor ceases to be a Subsidiary, so long as, immediately after giving effect to the consummation of such transaction, no Default or Event of Default results therefrom; provided that, if so required by this Guaranty or the Participation Agreement, the Required Participants shall have consented to such transaction and the terms of such consent shall not have provided otherwise.

(b) Further, the Administrative Agent may (and is hereby irrevocably authorized by each Participant to), upon the request of the Parent Guarantor or Lessee, release any Subsidiary Guarantor from its obligations under this Guaranty if such Subsidiary Guarantor is no longer a Material Domestic Subsidiary, becomes an Excluded Subsidiary or is otherwise not required pursuant to this terms of this Guaranty to provide a Subsidiary Guaranty; provided that, unless such Subsidiary Guarantor is a Bank Credit Agreement Specified Loan Party, prior to or substantially concurrently with the release of such Subsidiary Guarantor pursuant to this Section 17(b), it ceases to be a loan party (whether as a guarantor and/or borrower) under the Bank Credit Agreement and related loan documents.

(c) Further, the Administrative Agent may (and is hereby irrevocably authorized by each Participant to), upon the request of the Parent Guarantor or Lessee, release any Guarantor from its obligations under this Guaranty if such release is approved, authorized or ratified by the requisite Participants pursuant to Section 15.5 of the Participation Agreement.

(d) At such time as the Liabilities (other than Liabilities expressly stated to survive such payment and termination) shall have been indefeasibly paid in full in cash, all obligations of each Guarantor under this Guaranty shall automatically terminate (other than with respect to Liabilities expressly stated to survive such payment and termination), all without delivery of any instrument or performance of any act by any Person (it being agreed that, upon indefeasible payment in full in cash of the Liabilities (other than (i) Liabilities expressly stated to survive such payment and termination and (ii) contingent Liabilities for costs, expenses, indemnities and similar obligations not then due and payable), Sections 8 and 9 of this Guaranty

shall automatically terminate, notwithstanding the survival of this Guaranty with respect to Liabilities expressly stated to survive such payment and termination).

(e) Upon request by the Administrative Agent at any time, the Participants will confirm in writing the Administrative Agent’s authority to release any particular Guarantor pursuant hereto. In connection with any termination or release pursuant to this Section 17, the Administrative Agent shall (and is hereby irrevocably authorized by each Participant to) execute and deliver to any Guarantor or Lessee, at such Guarantor’s or Lessee’s expense, all documents that such Guarantor or Lessee shall reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to this Section 17 shall be without recourse to or warranty by the Administrative Agent except with respect to any customary further assurances that are expressly agreed to in writing by the Administrative Agent.

Section 18. Contribution with Respect to Liabilities.

(a) To the extent that any Guarantor shall make a payment under this Guaranty (a “Guarantor Payment”) which, taking into account all other Guarantor Payments then previously or concurrently made by any other Guarantor, exceeds the amount which otherwise would have been paid by or attributable to such Guarantor if each Guarantor had paid the aggregate Liabilities satisfied by such Guarantor Payment in the same proportion as such Guarantor’s “Allocable Amount” (as defined below) (as determined immediately prior to such Guarantor Payment) bore to the aggregate Allocable Amounts of each of the Guarantors as determined immediately prior to the making of such Guarantor Payment, then, following indefeasible payment in full in cash of the Liabilities and termination of this Guaranty, such Guarantor shall be entitled to receive contribution and indemnification payments from, and be reimbursed by, each other Guarantor for the amount of such excess, pro rata based upon their respective Allocable Amounts in effect immediately prior to such Guarantor Payment.

(b) As of any date of determination, the “Allocable Amount” of any Guarantor shall be equal to the excess of the fair saleable value of the property of such Guarantor over the total liabilities of such Guarantor (including the maximum amount reasonably expected to become due in respect of contingent liabilities, calculated, without duplication, assuming each other Guarantor that is also liable for such contingent liability pays its ratable share thereof), giving effect to all payments made by other Guarantors as of such date in a manner to maximize the amount of such contributions.

(c) This Section 18 is intended only to define the relative rights of the Guarantors, and nothing set forth in this Section 18 is intended to or shall impair the obligations of the Guarantors, jointly and severally, to pay any amounts as and when the same shall become due and payable in accordance with the terms of this Guaranty.

(d) The parties hereto acknowledge that the rights of contribution and indemnification hereunder shall constitute assets of the Guarantor or Guarantors to which such contribution and indemnification is owing.
