      rights it may have to set off, net, recoup or otherwise withhold or
      suspend or condition payment or performance of any obligation between it
      and the other party hereunder against any obligation between it and the

      paragraph of Section 6(e) of the ISDA Form Master Agreement shall not
      apply for purposes of this Transaction.

(s)   Additional Termination Events. Additional Termination Events will apply.

      (i) If a Ratings Event has occurred and BSFP has not, within 30 days,

      shall have occurred with respect to BSFP and BSFP shall be the sole
      Affected Party with respect to such an Additional Termination Event.

      (ii) Cap Disclosure Event. If, upon the occurrence of a Cap Disclosure
      Event (as defined in Paragraph 6(u)(ii) below), BSFP has not, within the
      greater of (5) five calendar days or (3) three Business Days after such
      Cap Disclosure Event complied with any of the provisions set forth in

      BSFP shall, at its own expense and subject to the Rating Agency Condition,
      either

            (i)   assign this Transaction to an entity that satisfies (or whose

                  Condition;

provided that the failure by BSFP to take any action specified in (i)-(iv) above

an Additional Termination Event under the ISDA Form Master Agreement with
respect to which BSFP shall be the sole Affected Party and this Transaction
shall be the sole Affected Transaction.

(b)   If BSFP fails to satisfy the Replacement Ratings (a "Replacement Event"),
      then BSFP shall, at its own expense and subject to the Rating Agency
      Condition, either:

            (i)   assign this Transaction to an entity that satisfies (or whose
                  credit support provider satisfies) the Required Ratings;

            (ii)  obtain a guaranty of an entity that satisfies the Required
                  Rating to guaranty BSFP's obligations under this Transaction;
                  or

            (iii) take any other action that satisfies the Rating Agency
                  Condition;

provided that the failure by BSFP to take any action specified in (i)-(iii)
above on or prior to the 10th Local Business Days after such Replacement Event
shall constitute an Additional Termination Event under the ISDA Form Master
Agreement with respect to which BSFP shall be the sole Affected Party and this

      Disclosure. If permitted by Regulation AB, any required Cap Financial
      Disclosure may be provided by incorporation by reference from reports
      filed pursuant to the Exchange Act.

recommendation to enter into such transaction; it being understood that
information and explanations related to the terms and conditions of such
