For purposes of this provision a "Beneficial Owner" means the Person who has the right to sell, transfer or otherwise dispose of an interest in Senior Secured Insured Quarterly Notes and the right to receive the proceeds therefrom, as well as the interest and principal payable to the Holder thereof. In general, a determination of beneficial ownership in the Senior Secured Insured Quarterly Notes will be determined by the Company, in its sole discretion, which determinations shall be final and binding on all parties. Unless the Senior Secured Insured Quarterly Notes have been declared due and payable prior to their maturity by reason of an Event of Default, the personal representative or other Person authorized to represent the estate of the deceased Beneficial Owner or from a surviving joint tenant(s) or tenant(s) by the entirety (each, a "Representative") of a deceased Beneficial 14 Owner has the right to request redemption prior to Stated Maturity of all or part of such interest, expressed in integral multiples of $1,000 principal amount, in the Senior Secured Insured Quarterly Notes, and the Company will redeem the same subject to the limitations that the Company will not be obligated to redeem, during the period from the Original Issue Date through and including June 1, 2000 (the "Initial Period"), and during any twelve-month period which ends on and includes each June 1, thereafter (each such twelve-month period being hereinafter referred to as a "Subsequent Period"), (i) on behalf of a deceased Beneficial Owner any interest principal amount of $25,000 or (ii) interests in the Senior Secured Insured Quarterly Notes in an aggregate principal amount exceeding $1,650,000. A request for redemption may initiated by the Representative of a deceased Beneficial Owner at any time and in any principal amount in integral multiples of $1,000. Representatives of deceased Beneficial Owners must make arrangements with the Participant through whom such interest is owned in order that timely presentation of redemption requests can be made by the Participant to the Senior Trustee. If the Company, although not obligated to do so, chooses to redeem interests of any deceased Beneficial Owner in the Senior Secured Insured Quarterly Notes in the Initial Period or any Subsequent Period in excess of the $25,000 limitation, such redemption, to the extent that it exceeds the $25,000 limitation for any deceased Beneficial Owner, shall not be included in the computation of the $1,650,000 limitation for such initial Period or such Subsequent Period, as the case may be, or for any succeeding Subsequent Period. Any Senior Secured Insured Note (or portion thereof) tendered pursuant to the redemption request may be withdrawn by a written request by the Representative received by the Senior Trustee at least 10 days prior to its repayment. Subject to the $25,000 and $1,650,000 limitations, the Company will, after the death of any Beneficial Owner, redeem the interest of such Beneficial Owner in the Senior Secured Insured Quarterly Notes within 60 days following receipt by the Senior Trustee of a redemption request. The Senior Trustee will notify the Company promptly after receipt of any redemption request and the Company will provide all funds necessary for such redemption prior to the date of redemption to the Paying Agent. If redemption requests exceed the aggregate principal amount of interests in Senior Secured Insured Quarterly Notes required to be redeemed during the Initial Period or during any Subsequent Period, then such excess redemption requests will be applied in the order received by the Senior Trustee to successive Subsequent Periods, regardless of the number of Subsequent Periods required to redeem such interests. All redemption requests will be redeemed in the order in which trustee receives the redemption request. To obtain repayment pursuant to a redemption request, the Representative must provide to the Participant (i) a written request for repayment signed by the Representative, and such signature must be guaranteed by a member firm of a registered national securities exchange or of the NASD or a commercial bank or trust company having an office or correspondent in the United States, (ii) appropriate evidence satisfactory to the Company and the Senior Trustee that (A) the Representative has authority to act on behalf of the deceased Beneficial Owner, (B) the death of such Beneficial Owner has occurred and (C) the deceased was the owner of a beneficial interest in such Senior Secured Insured Quarterly Note at the time of death, (iii) if applicable, a properly executed assigned or endorsed, and (iv) if the beneficial interest in such Senior Secured Insured Quarterly Note is held by a nominee of the deceased Beneficial Owner, a certificate satisfactory to the Senior Trustee from such nominee attesting to the deceased's ownership of a beneficial interest in such Senior 15 Secured Insured Quarterly Note. The Participant will provide these documents to the Senior Trustee. All questions as to the eligibility or validity of any exercise of redemption on behalf of a deceased Beneficial Owner will be determined by the Company, in its sole discretion, which determinations will be final and binding on all parties. For purposes of this provision an interest in Senior Secured Insured Quarterly Notes held in tenancy by the entirety, joint tenancy or by tenants in common will be deemed to be held by a single Beneficial Owner and the death of a tenant by the entirety, joint tenant or tenant in common will be deemed the death of a Beneficial Owner. The death of a Person who, during his lifetime, was entitled to subsequently all of the rights of a Beneficial Owner of an interest in the Senior Secured Insured Quarterly Notes will be deemed the death of the Beneficial Owner, regardless of the recordation of such interest on the records of the Participant, if such rights can be established to the satisfaction of the Participant and the Company. In the case of any redemption request which is presented pursuant to this provision and which has not been fulfilled at the time of the Company gives notice of its election to partially redeem Senior Secured Insured Quarterly Notes as described in item 3 above, such interest or portion thereof shall not be subject to redemption pursuant to such item 3 subject to redemption pursuant to this provision.
