ARTICLE TWO AMENDMENTS SECTION 2.1 INDENTURE AMENDMENTS. The Indenture is hereby amended by amending and restating Section 4.19 of the Indenture in its entirety to read as follows: "The Company shall maintain and shall cause each Restricted Subsidiary to maintain, in full force and effect, in-orbit insurance against at least such risks as are usually insured against in the same general area by companies engaged in the same or a similar business (a) prior to commercial operation of the satellite that is to replace Morelos II (the "Replacement Satellite"), with respect to Solidaridad 1 and Solidaridad 2 in an amount at least equal to $50 million in excess of the replacement cost (including launch fees) with respect to each of Solidaridad 1 and Solidaridad 2, provided that for so long as Moody's maintains a credit rating of Loral of Baa3 or better or S&P maintains a credit rating of Loral of BBB- or better, the Company or any Restricted Subsidiary may self-insure a portion of such in-orbit insurance in an amount not to exceed $25 million with respect to each of Solidaridad 1 and Solidaridad 2 to the extent such self-insurance is fully and unconditionally Guaranteed by Loral; and provided, further, that neither the Company nor any Restricted Subsidiary shall be required to maintain such $50 million of insurance in excess of the replacement cost insurance to the extent the Company and its Restricted Subsidiaries are not required to maintain such $50 million of excess insurance pursuant to the Senior Secured Credit Facilities or the Senior Secured Floating Rate Notes and (b) at all times after commercial operation of the Replacement Satellite, with respect to Solidaridad 1 and Solidaridad 2, and at all times with respect to the Replacement Satellite and with respect to each replacement satellite therefor, in an amount at least equal to $25 million in excess of the replacement cost (including launch fees) with respect to each satellite (including Solidaridad 1, Solidaridad 2 and the Replacement Satellite); provided that for so long as Moody's maintains a credit rating of Loral of Baa3 or better or S&P maintains a credit rating of Loral of BBB- or better, the Company or any Restricted Subsidiary may self-insurance a portion of such in-orbit insurance in an amount not to exceed $25 million with respect to each satellite to the extent such self-insurance is fully and unconditionally Guaranteed by Loral; and provided, further, that neither the Company nor any Restricted Subsidiary shall be required to maintain such $25 million of insurance in excess of the replacement cost insurance to the extent the Company and its Restricted Subsidiaries are not required to maintain such $25 million of excess insurance pursuant to the Senior Secured Credit Facilities or the Senior Secured Floating Rate Notes. All insurance required to be maintained hereunder shall be obtained from insurers that are customary in the satellite telecommunications industry. Within 30 days following any date on which the Company is required to obtain insurance pursuant to this Section 4.19, the Company shall deliver to a Trust Officer of the Trustee an insurance certificate certifying the amount of insurance then carried and in full force and effect, and an Officers' Certificate stating that such insurance, together with any other insurance maintained by the Company, complies with the Indenture. In addition, the Company shall cause to be delivered to the Trustee no less than once each year an insurance certificate setting forth the amount of insurance then carried, which insurance certificate shall entitle the Trustee to: (i) notice of any claim under any such insurance policy, and (ii) at least 30 days' notice from the provider of such insurance prior to the cancellation of any such insurance. In the event that the Company (or any Guarantor) receives proceeds from insurance 2 relating to any satellite, the Company (or any Guarantor) may use a portion of such proceeds to repay any vendor or third-party purchase money financing pertaining to such satellite that is required to be repaid by reason of the loss giving rise to such insurance proceeds. The Company (or any Guarantor) may use the remainder of such proceeds to develop, construct, launch and insure a replacement satellite (including components for a related ground spare) if such replacement satellite is of comparable or superior technological capability as compared with the satellite being replaced and has at least as much transmission capacity as the satellite being replaced; provided the Company delivers to the Trustee an Officers' Certificate certifying that such replacement satellite is scheduled to be launched within 24 months of the receipt of such proceeds. Any such proceeds not used as permitted by this paragraph shall be applied, within 90 days after the expiration of such 24 month period or such earlier date that the Company notifies the Trustee that it does not intend to apply such proceeds as provided above, to permanently reduce Indebtedness of the Company under the Senior Secured Credit Facilities or the Senior Secured Floating Rate Notes, or shall constitute "Excess Proceeds" for purposes of Section 4.18."
