        • • • • (1)           the Company shall use Commercially Reasonable Efforts, subject to clause (v) of this Section 2.2(a), to raise sufficient net proceeds from the issuance of Qualifying Capital Securities during a 180-day period ending on the date, not more than 15 and not less than 10 Business Days prior to any Repayment Date, on which the Company delivers the notice required by clause (v) of this Section 2.2(a) and Section 5.1, to permit repayment of the Debentures in full on the Scheduled Maturity Date pursuant to clause (i) of this Section 2.2(a); and

                (2)           if the Company is unable for any reason to raise sufficient proceeds from the issuance of Qualifying Capital Securities to permit repayment in full of the Debentures on the applicable Repayment Date, the Company shall use Commercially Reasonable Efforts, subject to a Market Disruption Event to raise sufficient net proceeds from the issuance of Qualifying Capital Securities during a 90-day period ending on the date, not more than 15 and not less than 10 Business Days prior to the following Repayment Date, on which the Company delivers the notice required by clause (v) of this Section 2.2(a) and Section 5.1, to permit repayment of the Debentures in full on such following Repayment Date pursuant to clause (i)(z) of this Section 2.2(a); and

        (vi)          Net proceeds of the issuance of any Qualifying Capital Securities that the Company is permitted to apply to repayment of the Debentures on any Repayment Date will be applied, first, to pay deferred interest (including compounded interest thereon) to the extent of Eligible Proceeds raised pursuant to Section 2.6, second, to pay current interest to the extent not paid from other sources and, third, to repay the outstanding principal amount of Debentures, subject to a minimum principal amount of $5 million to be repaid on any Repayment Date; provided that if the Company is obligated to sell Qualifying Capital Securities and apply the net proceeds to payments of principal of or interest on any Pari Passu Securities in addition to the Debentures, then on any date and for any period the amount of net proceeds received by the Company from those sales and available for such payments shall be applied to the Debentures and those other Pari Passu Securities having the same scheduled maturity date as the Debentures pro rata in accordance with their respective outstanding principal amounts and none of such net proceeds shall be applied to any other securities having a later scheduled maturity date until the principal of and all accrued and unpaid interest on the Debentures has been paid in full.  If the Company raises less than $5 million of proceeds from the sale of Qualifying Capital Securities during the relevant 180-day or 90-day period, the Company will not be required to repay any Debentures on the Scheduled Maturity Date or the next Quarterly Interest Payment Date, as applicable, but will retain those net proceeds and use them to repay the Debentures on the next Quarterly Interest Payment Date as of which the Company has raised at least $5 million of net proceeds.

        (vii)         The Company shall not amend the Replacement Capital Covenant to impose additional restrictions on the type or amount of Qualifying Capital Securities that the Company may include for purposes of determining when repayment, redemption or purchase of the Debentures is permitted, except with the consent of Holders of a majority of the principal amount of the Debentures.  Except as aforesaid, the Company may amend or supplement the Replacement Capital Covenant in accordance with its terms and without the consent of the Holders of the Debentures.

(b)           The Debentures are initially issuable solely as Global Securities.  Registered Debentures shall be physically transferred to all beneficial owners in definitive form in exchange for their beneficial interests in a Global Security if the Depositary with respect to such Global Securities notifies the Company that it is unwilling or unable to continue as Depositary for such Global Security, as the case may be, and a successor Depositary is not appointed by the Company within 90 days of such notice.

16

arrears on February 15, May 15, August 15 and November 15 of each year, commencing on August 15, 2017 (each such date, a " Quarterly Interest Payment Date " and, together with Semi-Annual Interest Payment Dates, each, an " Interest Payment Date ").
