the Estate which the Debtor determines to be burdensome or of inconsequential
benefit to the Estate. The Debtor shall mail written notice of any such
compromise, disposition or abandonment to those parties who have filed, after
Confirmation, a written request that all notices be mailed to them. If the
Debtor does not receive any written notice of an objection and demand for a
hearing on the compromise, disposition or abandonment within fifteen (15) days
of the mailing of such notice, the Debtor shall submit an order to the
Bankruptcy Court for its approval. Upon Final Order of the Bankruptcy Court, the

undisputed portion of such fees and expenses and shall reserve monies in the
amount of the disputed fees and expenses pending resolution of said objection by
(i) agreement between the professional requesting such fees and expenses and the
disputing party, or (ii) resolution of the disputed amount by the Bankruptcy
Court pursuant to a Final Order. Professionals shall not otherwise be required
to file applications for Bankruptcy Court approval of post-Confirmation fees and
expenses.

(unless a current or correct address cannot be determined after reasonable
inquiry) shall become the property of the Debtor and shall be added to and
