Item 5.       Other Events

On September 24, 2001, NeighborCare Pharmacy Services, Inc., a subsidiary of
Genesis Health Ventures, Inc. (the "Company" or "Genesis") entered into an asset
purchase agreement to buy substantially all of the assets of American
Pharmaceutical Services, Inc. ("APS"), and certain other corporate entities, all
of which are subsidiaries of either Mariner Health Group ("MHG") or Mariner Post
Acute Network ("MPAN") (such selling entities, collectively with MHG and MPAN,
are referred to as the "Sellers"), for approximately $42 million plus up to $18
million in deferred payments contingent on performance.

The sale is subject to several conditions including, U.S. Bankruptcy Court
approval of an overbidding procedure, followed by a competitive bidding process
and final court approval of the prevailing bid in the MPAN and MHG chapter 11
cases. Accordingly, there can be no assurance that the transaction will be
consummated or consummated under the terms described above.

In order to fulfill the Sellers' respective obligations under the Bankruptcy
Code to obtain the highest and best price for the Sellers' assets, the Sellers
intend to solicit bids in excess of the bid made by the Company. If no qualified
higher bids are received, the Sellers will be required to submit the Genesis
asset purchase agreement to their Bankruptcy Court for approval.

There can be no assurances that the Genesis bid to purchase the Sellers' assets
will not be countered by a more attractive bid made by a third party, nor can
there be any assurances that the Genesis bid, if accepted by the Sellers, would
be approved by their Bankruptcy Court.

If the Genesis bid is ultimately accepted and approved by the Sellers'
Bankruptcy Court, the Company intends to finance the purchase with proceeds
under the delayed draw term loan component of its $515 million financing
facility entered into by the Company with a lending group in connection with its
emergence from proceedings under Chapter 11 of the Bankruptcy Code.

The Sellers' assets contemplated in the asset purchase agreement consist of 33
institutional pharmacies, three retail pharmacies and four respiratory therapy
sites located in 15 states generating annual revenues of approximately $250
million.
