(iii) BBI and/or certain of its Subsidiaries will enter into a senior secured credit facility (the “BBI Credit Facility”) comprising two sub-facilities consisting of a term loan sub-facility and a revolving credit sub-facility, which BBI Credit Facility may be secured by the assets of BBI and some or all of its Subsidiaries, provided that neither the Borrower nor any of its Subsidiaries (other than BBI and its Subsidiaries) shall be a guarantor or otherwise similarly obligated with respect to the BBI Credit Facility;

(iv) as partial consideration for certain of the sales, contributions and transfers referenced in clause (i) above, the Borrower and/or certain of its Subsidiaries may receive certain promissory notes from BBI and/or certain of its Subsidiaries, which promissory notes will be paid and satisfied by application of the net cash proceeds of the draw downs of the term loan and the revolving credit sub-facilities (excluding any draw down of the revolving credit sub-facility for the working capital purposes of BBI or any of its Subsidiaries) under the BBI Credit Facility and/or from other cash of BBI and its Subsidiaries in connection with the consummation of the BBI Transaction;

Non-BBI Subsidiaries, on the one hand, and BBI and its Subsidiaries, on the other hand shall not exceed $5,000,000 and (II) the aggregate principal amount of all intercompany debt owed by the Borrower and the Non-BBI Subsidiaries to BBI and its Subsidiaries shall not exceed $25,000,000; and

This summary sets forth only the fundamental terms, elements and transactions constituting the BBI Transaction. As used in this Fifth Amendment, the term “BBI Transaction” shall include all component transactions within the series of transactions described above and all agreements, instruments and other documents (including those referenced above) executed or entered into in furtherance thereof.
