WHEREAS, the Guarantor wishes to induce the Lessor to enter into a certain Lease (as defined below) with a Subsidiary (as defined below) of the Guarantor; and WHEREAS, the Lessor is unwilling to enter into the Lease unless the Guarantor enters into this Guaranty; NOW, THEREFORE, in order to induce the Lessor to enter into the Lease, the Guarantor hereby agrees as follows: SECTION 1 DEFINED TERMS; RULES OF CONSTRUCTION 1.1Definitions.

All accounting terms not specifically defined herein shall be construed in accordance with GAAP. 1.3Use of Certain Terms. Unless the context of this Guaranty requires otherwise, the plural includes the singular, the singular includes the plural, and "including" has the inclusive meaning of "including without limitation." The words "hereof," "herein," "hereby," "hereunder" and other similar terms of this Guaranty refer to this Guaranty as a whole and not exclusively to any particular provision of this Guaranty. All pronouns and any variations thereof shall be deemed to refer to masculine, feminine or neuter, singular or plural, as the identity of the Person or Persons may require. 1.4Headings and References. Section and other headings are for reference only, and shall not affect the interpretation or meaning of any provision of this Guaranty. Unless otherwise provided, references to Articles, Sections, Schedules and Exhibits shall be deemed references to Articles, Sections, Schedules and Exhibits of this Guaranty.

A reference to any law shall mean that law as it may be amended, modified or supplemented from time to time, and any successor law. A reference to a Person includes the successors and assigns of such Person, but such reference shall not increase, decrease or otherwise modify in any way the provisions in this Guaranty governing the assignment of rights and obligations under or the binding effect of any provision of this Guaranty. SECTION 2 GUARANTY 2.1Guaranty. Subject to the terms and conditions in this Guaranty, the Guarantor absolutely, unconditionally and irrevocably guarantees to the Lessor and each Related Assignee that (i) all Payment Obligations will be promptly paid in full as and when due in accordance with the terms thereof whether at the stated due date, by acceleration or otherwise, and (ii) the Lessee will duly and punctually perform, comply with and observe all Covenant Obligations as and when required in accordance with the terms thereof, in each case, without regard to whether such Obligation is direct or indirect, absolute or contingent, now or hereafter existing or owing, voluntary or involuntary, created or arising by contract, operation of law or otherwise or incurred or payable before or after commencement of any proceedings by or against the Lessee under any bankruptcy law. If an event permitting the exercise of remedies under the Operative Documents shall at any time have occurred and be continuing and such exercise, or any consequences thereof provided in the Operative Documents, shall at such time be prevented by reason of the pendency against the Lessee of a case or proceeding under a bankruptcy or insolvency law, the Guarantor agrees that, solely for purposes of this Guaranty and its obligations hereunder, the Obligations and all other amounts payable under the Operative Documents shall be deemed to have been declared in default, with all attendant consequences as provided in the Operative Documents as if such declaration of default and the consequences thereof had been accomplished in accordance with the terms of the Operative Documents, and the Guarantor shall forthwith pay any amounts guaranteed hereunder, without further notice or demand. 2.2Guaranty Absolute. This Guaranty is an absolute, unlimited and continuing guaranty of performance and payment (and not of collection) of the Obligations. This Guaranty is in no way conditioned upon any attempt to collect from the Lessee or upon any other event or contingency, and shall be binding upon and enforceable against the Guarantor without regard to the validity, regularity or enforceability of any Operative Document or the Notes, or of any term thereof. The obligations of the Guarantor set forth herein constitute the full recourse obligations of the Guarantor enforceable against it to the full extent of all its assets and properties, notwithstanding any provision in the Lease limiting the liability of any Person, or any agreement by a trustee or a Noteholder under a Financing Arrangement to look for payment with respect thereto, solely to certain property and other collateral as described in the Operative Documents. Without limiting the foregoing, it is agreed and understood that (a) repeated and successive demands may be made and recoveries may be had hereunder as and when, from time to time, the Lessee shall be in default with respect to the Obligations under the terms of the Lease, and (b) notwithstanding the recovery hereunder for or in respect of any given default with respect to the Obligations by the Lessee under the Lease, this Guaranty shall remain in full force and effect and shall apply to each and every subsequent default with respect to the Obligations. 2.3Reinstatement. In case any Operative Document shall be terminated as a result of the rejection thereof by any trustee, receiver or liquidating agent of the Lessee or any of its properties in any bankruptcy, insolvency, reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar proceeding, the Guarantor's obligations hereunder shall continue to the same extent as if such agreement had not been so rejected. The Guarantor agrees that this Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time payment to the Lessor or any Related Assignee of the Obligations or any part thereof is rescinded or must otherwise be returned by the Lessor or such Related Assignee upon the insolvency, bankruptcy or reorganization of the Lessee, or otherwise, as though such payment to the Lessor or such Related Assignee had not been made. 2.4Enforcement. The Guarantor shall pay all costs, expenses and damages incurred (including reasonable attorneys' fees and disbursements) in connection with the enforcement of the Obligations to the extent that such costs, expenses and damages are not paid by the Lessee, and in connection with the enforcement of the obligations of the Guarantor under this Guaranty. 2.5Guaranty Not Subject to Setoff, etc. The obligations of the Guarantor hereunder shall not be subject to any counterclaim, setoff, deduction or defense (other than payment or performance) based upon any claim the Guarantor or the Lessee may have against the Lessor or any Related Assignee or any claim the Guarantor may have against the Lessee or any other Person and shall remain in full force and effect without regard to, and shall not be released, discharged, reduced or in any way affected by any circumstance or condition whatsoever (whether or not the Guarantor shall have any knowledge or notice thereof) which might constitute a legal or equitable discharge or defense including, but not limited to, (a) the amending, modifying, supplementing or terminating (by operation of law or otherwise), expressly or impliedly, of any Operative Document, or any other instrument applicable to the Lessee or to its Obligations, or any part thereof; (b) any failure on the part of the Lessee to perform or comply with any term of any Operative Document or any failure of any other Person to perform or comply with any term of any Operative Document; (c) any waiver, consent, change, extension, indulgence or other action or any action or inaction under or in respect of any Operative Document or this Guaranty, whether or not the Lessor, the Lessee or the Guarantor has notice or knowledge of any of the foregoing; (d) any bankruptcy, insolvency, reorganization, arrangement, readjustment, composition, liquidation or similar proceeding with respect to the Lessor, the Guarantor or the Lessee, or their respective properties or their creditors, or any action taken by any trustee or receiver or by any court in any such proceeding; (e) any furnishing or acceptance of additional security or any release of any security (and the Guarantor authorizes the Lessor or each Related Assignee to furnish, accept or release said security); (f) any limitation on the liability or Obligations of the Lessee under any Operative Document (except as expressly set forth therein) or any termination (by operation of law or otherwise), cancellation (by operation of law or otherwise), frustration or unenforceability, in whole or in part, of any Operative Document or the Notes, or any term thereof; (g) any lien, charge or encumbrance on or affecting the Guarantor's, the Lessor's or the Lessee's respective assets and properties; (h) any act, omission or breach on the part of the Lessor or any Related Assignee under any Operative Document, or any other agreement at any time existing between the Lessor and the Lessee or any other law, governmental regulation or other agreement applicable to the Lessor or any Obligation; (i) any claim as a result of any other dealings among the Lessor, any Related Assignee, the Guarantor, any Noteholder or any of them; (j) the assignment or transfer of this Guaranty, any Operative Document (whether or not in accordance with and subject to the terms thereof) or any other agreement or instrument referred to in any Operative Document or applicable to the Lessee or the Obligations by the Lessor to any other Person; (k) any change in the name of the Lessor, any Related Assignee, the Lessee or any other Person; (l) any subleasing or further subleasing of the Facility or any other Parcel of Property or Unit of Equipment or any part thereof, or any redelivery, repossession, sale, transfer or other disposition, surrender or destruction of the Facility or any other Parcel of Property or Unit of Equipment or any part thereof; (m) the transfer, assignment, mortgaging or purported transfer, assignment or mortgaging of all or any part of the interest of the Lessor, its successors or assigns, or the Lessee in the Facility or any other Parcel of Property or Unit of Equipment or any part thereof or the failure to record a mortgage on or with respect to all or any part of the Lessor's interest in the Facility or any part thereof or any other Recordable Document; (n) any failure of title with respect to the interest of the Lessor or the Lessee, or their respective successors and assigns, in the Facility or any other Parcel of Property or Unit of Equipment or any part thereof; (o) any defect in the 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 Facility or any other Parcel of Property or Unit of Equipment or any part thereof by the 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, or any Event of Loss), and regardless of the duration thereof (even though such duration would otherwise constitute a frustration of the Lease), whether or not without fault on the part of the Lessee or any other Person; (p) any merger or consolidation of the Lessee or the Guarantor into or with any other Person or any direct or indirect sale, lease or transfer of any other assets of the Lessee or the Guarantor to any other Person; (q) any change in the ownership of any shares of capital stock of the Guarantor or the Lessee (including any such change which results in the Guarantor no longer owning capital stock of the Lessee); or (r) any other event or circumstance whatsoever (other than indefeasible payment and performance in full of the Obligations). 2.6Waiver. The Guarantor unconditionally waives: (a) notice of any of the matters referred to in Section 2 hereof; (b) all notices which may be required by statute, rule of law or otherwise (except as expressly required to be given to the Guarantor by any Operative Document) to preserve any rights against the Guarantor hereunder, including notice of the acceptance of this Guaranty by the Lessor or any Related Assignee, or the creation, renewal, extension, modification or accrual of the Obligations or notice of any other matters relating thereto, any presentment, demand, notice of dishonor, protest or nonpayment of any damages or other amounts payable under any Operative Document; (c) any requirement for the enforcement, assertion or exercise of any right, remedy, power or privilege under or in respect of any Operative Document, including diligence in collection or protection of or realization upon the Obligations or any part thereof or any collateral therefor; (d) any requirement of diligence; (e) any requirement to mitigate the damages resulting from a default or termination under any Operative Document, except that this shall not relieve the Lessor of any such obligation; (f) the occurrence of every other condition precedent to which the Guarantor or the Lessee may otherwise be entitled, except as provided in any Operative Document; and (g) the right to require the Lessor or any Related Assignee to proceed against the Lessee or any other Person liable on the Obligations, to proceed against or exhaust security held from the Lessee or any other Person, or to pursue any other remedy in the Lessor's or such Related Assignee's power whatsoever, and the Guarantor waives the right to have the property of the Lessee first applied to the discharge of the Obligations. The Lessor or any Related Assignee may, at its election, exercise any right or remedy it might have against the Lessee or any security held by the Lessor or such Related Assignee, including the right to foreclose upon any such security by judicial or nonjudicial sale, without affecting or impairing in any way the liability of the Guarantor hereunder, except to the extent the Obligations have been indefeasibly paid or satisfied, and the Guarantor waives any defense arising out of the absence, impairment or loss of any right of reimbursement, contribution or subrogation or any other right or remedy of the Guarantor against the Lessee or any such security, whether resulting from such election by the Lessor or such Related Assignee or otherwise. The Guarantor waives any defense arising by reason of any disability or other defense of the Lessee, or by reason of the cessation from any cause whatsoever of the liability, either in whole or in part, of the Lessee to the Lessor for the Obligations. The Guarantor understands that the Lessor's or any Related Assignee's exercise of certain rights and remedies contained in the Operative Documents may affect or eliminate the Guarantor's rights of subrogation against the Lessee and that the Guarantor may therefore incur partially or totally nonreimbursable liability hereunder; nevertheless, the Guarantor hereby authorizes and empowers the Lessor, its successors, endorsees and/or assignees (including each Related Assignee) to exercise in its or their sole discretion, any rights and remedies, or any combination thereof, which may then be available, it being the purpose and intent of the Guarantor that its obligations hereunder shall be absolute, independent and unconditional under any and all circumstances. The Guarantor assumes the responsibility for being and keeping informed of the financial condition of the Lessee and of all other circumstances bearing upon the risk of nonpayment of the Obligations and agrees that neither the Lessor nor any Related Assignee shall have any duty to advise the Guarantor of information regarding any condition or circumstance or any change in such condition or circumstance. The Guarantor acknowledges that neither the Lessor nor any Related Assignee has made any representation to the Guarantor concerning the financial condition of the Lessee.

The Guarantor is a corporation duly organized, validly existing and in good standing under the laws of the State of New York, and is duly qualified as a foreign corporation and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Guarantor has full power and authority to own or hold under lease the properties it purports to own or hold under lease, to transact the business it transacts and to execute and deliver and perform the provisions of this Guaranty. 4.2Authorization, etc. This Guaranty has been duly authorized by all necessary corporate and shareholder action on the part of the Guarantor, and this Guaranty constitutes a legal, valid and binding obligation of the Guarantor enforceable against the Guarantor in accordance with its terms, except as such enforceability may be limited by (a) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors' rights generally and (b) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). 4.3Disclosure. The Private Placement Memorandum dated April 1999 (such Private Placement Memorandum together with any financial statements attached thereto, the "Memorandum"), relating to the transactions contemplated hereby fairly describes, in all material respects, the business and properties of the Guarantor and its Material Subsidiaries. None of this Guaranty, the Memorandum, and the financial statements listed in Schedule 4.5 to this Guaranty, taken as a whole, contains any untrue statement of a material fact or omits to state any material fact necessary to make the statements therein not misleading in light of the circumstances under which they were made. Except as disclosed in the Memorandum or in the financial statements listed in Schedule 4.5 to this Guaranty, since December 31, 1998, there has been no change in the financial condition, operations, business or properties of the Guarantor or any Material Subsidiary except changes that individually or in the aggregate would not reasonably be expected to have a Material Adverse Effect. 4.4Organization and Ownership of Shares of Material Subsidiaries. Schedule 4.4 to this Guaranty contains (except as noted therein) complete and correct lists of (i) the Material Subsidiaries, showing, as to each such Material Subsidiary, the correct name thereof, the jurisdiction of its organization, and the percentage of shares of each class of its capital stock or similar equity interests outstanding owned by the Guarantor and each other Subsidiary of the Guarantor and (ii) the Guarantor's directors and senior officers. All of the outstanding shares of capital stock or similar equity interests of each Material Subsidiary shown in Schedule 4.4 as being owned by the Guarantor and its Subsidiaries have been validly issued, are fully paid and nonassessable and are owned by the Guarantor or another Subsidiary free and clear of any Lien (except as otherwise disclosed in Schedule 4.4).

No Material Subsidiary is a party to or otherwise subject to any legal restriction or any agreement (other than this Guaranty, the agreements listed on Schedule 4.4 and customary limitations imposed by corporate law statutes and applicable regulatory requirements) restricting the ability of such Material Subsidiary to pay dividends out of profits or make any other similar distributions of profits to the Guarantor or any of its Subsidiaries that owns outstanding shares of capital stock of such Material Subsidiary. 4.5Financial Statements.

The Guarantor and its Material Subsidiaries have good and sufficient title to their respective properties that individually or in the aggregate are Material, including all such properties reflected in the most recent audited balance sheet described in Schedule 4.5 to this Guaranty or purported to have been acquired by the Guarantor or any Material Subsidiary after the date of such balance sheet (except as sold or otherwise disposed of in the ordinary course of business).

The Guarantor reasonably believes that all of its computer applications that are Material to the businesses and operations of the Guarantor and its Subsidiaries will on a timely basis be Year 2000 Compliant, except to the extent that a failure to do so would not reasonably be expected to have a Material Adverse Effect. The Guarantor has asked its Material vendors and suppliers about their plans for and progress in identifying and addressing problems that their computer systems may face in correctly processing date information related to the Year 2000 Problem and is developing contingency plans for any essential vendors and suppliers who fail to give the Guarantor sufficient credible information of their readiness as it affects the Guarantor's ability to be Year 2000 Compliant. As used in this Section 4.11(b), the term "Year 2000 Compliant" means all computer applications of the Guarantor that are Material to the businesses and operations of the Guarantor and its Subsidiaries will on a timely basis be able to perform properly date-sensitive functions involving all dates on and after January 1, 2000; and the term "Year 2000 Problem" means the risk that computer applications used by the Guarantor or any of its Subsidiaries may be unable to recognize and perform properly date-sensitive functions involving certain dates on and after January 1, 2000. 4.12 Compliance with ERISA.

Neither the Guarantor nor any ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined in section 3 of ERISA), and no event, transaction or condition has occurred or exists that would reasonably be expected to result in the incurrence of any such liability by the Guarantor or any ERISA Affiliate, or in the imposition of any Lien on any of the rights, properties or assets of the Guarantor or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or 412 of the Code, other than such liabilities or Liens as would not, individually or in the aggregate, be Material. (b) The present value of the aggregate benefit liabilities under each of the Plans (other than Multiemployer Plans), determined on the basis of the actuarial assumptions specified for funding purposes in such Plan's most recent actuarial valuation report, did not exceed the aggregate current value of the assets of such Plan allocable to such benefit liabilities. The term "benefit liabilities" has the meaning specified in section 4001 of ERISA and the terms "current value" and "present value" have the meaning specified in section 3 of ERISA. (c) The Guarantor and its ERISA Affiliates have not incurred withdrawal liabilities (and are not subject to contingent withdrawal liabilities) under section 4201 or 4204 of ERISA in respect of Multiemployer Plans that individually or in the aggregate are Material.

(e) The execution and delivery of this Guaranty will not involve any transaction that is subject to the prohibitions of section 406 of ERISA or in connection with which a tax could be imposed pursuant to Section 4975(c)(1)(A)-(D) of the Code. The representation by the Guarantor in the first sentence of this Section 4.12(e) is made in reliance upon and subject to the accuracy of the representations of the Note Purchasers in Section 2.2 of the Note Purchase Agreement as to the sources of the funds used to pay the purchase price of the Notes to be purchased by them thereunder. 4.13 Offering of the Notes and this Guaranty, Etc. Neither the Guarantor nor anyone authorized to act on its behalf has offered this Guaranty or the Notes or any similar securities for sale to, or solicited any offer to buy any of the same from, or otherwise approached or negotiated in respect thereof with, any Person other than the Note Purchasers and not more than 110 other institutional investors (all such other investors being "accredited investors" as defined under Rule 501(a) of the Securities Act). Neither the Guarantor nor anyone authorized to act on its behalf has taken, or will take, any action that would subject the execution and delivery of this Guaranty or the issuance or sale of the Notes to the registration requirements of Section 5 of the Securities Act. 4.14 Existing Indebtedness. Neither the Guarantor nor any Subsidiary is in default, and no waiver of default is currently in effect, in the payment of any principal or interest on any Indebtedness of the Guarantor or such Subsidiary and no event or condition exists with respect to any Indebtedness of the Guarantor or any Subsidiary that would permit one or more Persons to cause such Indebtedness to become due and payable before its stated maturity, except in each case for any default, event or condition which individually or in the aggregate would not reasonably be expected to have a Material Adverse Effect.
