Notwithstanding any other provision of this Agreement, SETA shall sell any available liquid asset (but, for the sake of clarity, such liquid assets shall exclude the BB Shares owned by SETA) to pay all or any portion of the then Outstanding Amount (the amount remaining then to be prepaid being the "Prepayment Amount"). 16 After the Prepayment Parties have agreed that SETA shall prepay the Prepayment Amount in accordance with the immediately above paragraph, the Prepayment Parties may, in addition, determine (a "Determination") that SETA will raise additional funds by issuing Consortium Interest (such Determination to include whether such Consortium Interest should be in the form of Debt Interest, Equity Interest, or a combination thereof, and the price and other terms by which SETA will issue any such Consortium Interest) or an alternative borrowing (and the price and other terms by which SETA will issue any such alternate indebtedness) to pay all of the then due Prepayment Amount; provided, however, that (except as specifically provided for in the last paragraph of this Clause 3.2.9) any Debt Interests issued hereunder shall be allocated among the Parties pari passu with their holdings of Consortium Interest, and on similar terms as the Debt Interest outstanding at such time (and should there be no Debt Interest outstanding at such time, such new Debt Interest will be under similar terms as those contained in the Long Term Loan Contracts).

If any applicable law or regulation (including any provision of the Transaction Documents or the governing instrument of a Party) prohibits the Parties from applying this Clause 3.2.10, then the Parties hereto agree that the non-defaulting Parties shall have the right to assign to any third party this right to purchase and to enforce the obligation to sell contained herein. 3.2.11 PREPAYMENT OF THE LOAN The Parties hereto may decide at any time that SETA shall prepay the Outstanding Amount of the Loan (as defined in the Senior Secured Credit Agreement).
