(b) Capitalized terms used herein and not otherwise defined herein shall have the meanings ascribed to such terms in the Consolidated Credit Agreement.

Except as otherwise expressly provided herein, any reference in this Guarantee to any Loan Document shall mean such document as amended, restated, supplemented or otherwise modified from time to time. SECTION 1.02. The Guarantee. (a) Subject to the provisions of Section 1.04, IGL herby unconditionally and irrevocably guarantees as a primary obligor and not merely as a surety the due and punctual payment when and as due (whether at stated maturity, by notice of prepayment, upon acceleration or otherwise) of the Obligations. IGL agrees that it shall pay on demand any of the Obligations for which it is liable pursuant to this Guarantee which has remained unpaid by the relevant Borrower for five Business Days after such amount is due or demanded from the relevant Borrower; provided that if an event referred to in Section 7.01(h) or (i) of the Consolidated Credit Agreement has occurred with respect to a Borrower, such amounts shall be payable on demand by IGL; provided further, that if an event referred to in Section 7.01(h) or (i) of the Consolidated Credit Agreement has occurred with respect to a Borrower, IGL shall have the right to pay all such amounts to the Administrative Agent without the necessity of any such demand. The obligations of IGL under this Guarantee shall be a guarantee of payment and not of collection. Upon payment by IGL of any sums to a Lender or an Agent as provided above in this Guarantee, IGL shall be subrogated to the rights of such Lender or Agent, as applicable, against such Borrower with respect to such payment; provided that all rights of IGL against a Borrower arising as a result thereof by way of right of subrogation or otherwise shall in all respects be subordinated and junior in right of payment to the prior payment in full of all the Obligations to the Lenders and the Agents and shall not be exercised by IGL prior to payment in full of all Obligations and termination of the Commitments. If any amount (other than any fees payable to IGL in respect of its guarantee hereunder) shall be paid to IGL on account of any amount paid by IGL pursuant to this Guarantee or otherwise at any time when all the Obligations shall not be paid in full and a Default or Event of Default shall have occurred and be continuing, such amount shall be held in trust by IGL for the benefit of the Agents and the Lenders and shall forthwith be paid to the Administrative Agent to be credited and applied to the Obligations, whether matured or unmatured. At such time as all Obligations owing to each Lender have been paid in full and its Commitment terminated, each Lender shall, in a reasonable manner, assign (subject to the continued effectiveness and the reinstatement provided for above) the amount of the Obligations owed to it and paid by IGL pursuant to this Guarantee to IGL, such assignment to be pro tanto to the extent to which the Obligations in question were discharged by IGL, or make such other disposition thereof as IGL shall reasonably direct (all without any representation or warranty by, or any recourse to, such Lender). SECTION 1.03. Guarantee Unconditional. Subject to the provisions of Section 1.04 and the Consolidated Credit Agreement, the obligations of IGL hereunder shall be unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by: (i) any rescission, extension, renewal, settlement, compromise, waiver or release in respect of any obligation of either Borrower under the Consolidated Credit Agreement, by operation of law or otherwise; (ii) any modification or amendment of or supplement to the Consolidated Credit Agreement; provided that any such modification, amendment or supplement which increases the obligations of IGL hereunder shall not be effective as to IGL without its consent. (iii) any guarantee or any release, impairment, non-perfection or invalidity of any direct or indirect security for any obligation of either Borrower under the Consolidated Credit Agreement; (iv) any change in the corporate existence, structure or ownership of either Borrower, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting either Borrower or their respective assets, or any resulting release or discharge of any obligation of either Borrower contained in the Consolidated Credit Agreement; (v) the existence of any claim, set-off or other rights that IGL may have at any time against either Borrower, any Agent, any Lender or any other corporation or person, whether in connection herewith or any unrelated transactions (including, without limitation, any default in the payment by either Borrower, or any other person of any fees payable to IGL in respect of its guarantee hereunder); provided that, subject to any subordination agreements relating to any such claims, nothing herein shall prevent the assertion of any such claim by separate suit or compulsory counterclaim; (vi) any invalidity or unenforceability relating to or against either Borrower for any reason of the Consolidated Credit Agreement, or any provision of applicable law or regulation purporting to prohibit the payment by either Borrower of the Obligations or any other amount payable by either Borrower under the Consolidated Credit Agreement; (vii) any other act or omission to act or delay of any kind by either Borrower, any beneficiary of this Guarantee, or any other corporation or person, or any other circumstance whatsoever, that might, but for the provisions of this paragraph, constitute a legal or equitable discharge of or defense to IGL's obligations hereunder or to the Obligations; (viii) any failure of any beneficiary of this Guarantee to assert any claim or demand or to enforce any right or remedy against either Borrower under the provisions of the Consolidated Credit Agreement, any other security document, any intercreditor document or any other loan document; or (ix) any failure of any beneficiary of this Guarantee to exercise any right or remedy against any other guarantor (including any subsidiary) of the Obligations. SECTION 1.04. Reduction of Principal Amounts Covered by Guarantee. Pursuant to Section 2.07(c) of the Consolidated Credit Agreement, the aggregate of the Commitments under the Tranches shall be automatically and permanently reduced, ratably among the Lenders in accordance with the amounts of their respective Commitments under the Tranches as set forth therein. Subject to the provisions of Section 1.05, the aggregate principal amount of the Loans, and reimbursement obligations (including cash collateralization obligations) in respect of Letters of Credit (collectively, "Principal Obligations"), covered by the guarantee obligations of IGL hereunder and in respect of which demands for payment may be made under this Guarantee shall, during each of the periods set forth below (each, a "Coverage Period"), be limited to the maximum aggregate amounts set forth below opposite such Coverage Period: Aggregate Coverage Period Principal Amount Through February 14, 1999 $50,000,000 $35,000,00 From February 15, 1999 through February 14, 2000 From $15,000,00 February 15, 2000 through January, 31 2001 After $0 January 31, 2001 Notwithstanding the foregoing, this Guarantee (i) shall remain in full force and effect at all times after a Coverage Period in an amount equal to the amount set forth opposite such Coverage Period above with respect to accrued and unpaid Principal Obligations in respect of which demand for payment under this Guarantee was duly made on IGL during such Coverage Period; provided that the aggregate liability of IGL under this Guarantee in respect of payment of Principal Obligations shall not in any event exceed $50,000,000 and (ii) shall cover the full amount of any interest accrued and unpaid on Principal Obligations in respect of which a demand for payment is or could (assuming such amount were due and unpaid) be made on IGL under this Guarantee on or before January 31, 2001 (except as provided in Section 1.05). In addition, notwithstanding the foregoing, all Obligations of the Borrowers for payment of amounts other than principal of and interest on the Loans (including, without limitation, in respect of indemnities, reimbursement of costs, yield protection, redeployment costs, tax gross-ups and reasonable expenses) shall be covered by IGL's guarantee hereunder without limitation, except to the extent any such payment obligation is attributable solely to a Principal Obligation, or interest on a Principal Obligation which, pursuant to the foregoing provisions, is not at the time covered by IGL's guarantee hereunder. During any Coverage Period, claims may be made on IGL hereunder in respect of any and all Principal Obligations not paid when due up to the full aggregate amount of Principal Obligations set forth opposite such Coverage Period in the table above, notwithstanding that (i) the aggregate amount of Principal Obligations under the Consolidated Credit Agreement may exceed the amount set forth in such table or (ii) only a portion of the Principal Obligations are at the time due and unpaid; provided, however, that the aggregate liability of IGL under this Guarantee in respect of Principal Obligations shall not in any event exceed $50,000,000. SECTION 1.05. Discharge only upon Payment in Full. Subject to the provisions of Section 1.04, IGL's obligations hereunder shall remain in full force and effect until the earliest of the date on which (x) the commitments under the Consolidated Credit Agreement shall have terminated and the Obligations (other than contingent indemnification obligations) shall have been paid in full, (y) payment has been made hereunder or (z) Chase or its Affiliates shall reduce their respective Commitments and/or sell participations in outstanding Loans such that their aggregate Commitments then outstanding under the Consolidated Credit Agreement as of such date shall be less than 25% of the total Commitments then outstanding as of such date. If at any time any Obligation is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of either Borrower or otherwise, IGL's obligations hereunder with respect to such payment shall be reinstated as though such payment had been due but not made at the time initially paid and if a demand for payment under this Guarantee could have been made in respect of such Obligation on such initial payment date or on any date thereafter in accordance with the provisions of Section 1.04 (assuming nonpayment of such Obligation when due on such initial payment date) then demand for payment may be made hereunder in respect of such Obligation notwithstanding the provisions of Section 1.04. SECTION 1.06. Waiver by IGL. Except to the extent set forth in Section 1.02 and as provided in the Consolidated Credit Agreement, IGL irrevocably waives acceptance hereof, presentment, demand, protest, notice of intent to accelerate, notice of acceleration and any notice not provided for herein or in the Consolidated Credit Agreement, as well as any requirement that at any time any action be taken by any beneficiary of this Guarantee, corporation or person against either Borrower, any other guarantor or any other entity or person. SECTION 1.07. Stay of Acceleration. If acceleration of the time for payment of any Obligation or any other amount payable by either Borrower under the Consolidated Credit Agreement is stayed upon the insolvency, bankruptcy or reorganization of either Borrower, all such amounts otherwise subject to acceleration under the terms of the Consolidated Credit Agreement shall nonetheless be payable by IGL hereunder as if no such stay was in effect.
