ITEM 2. DISPOSITION OF ASSETS

         This Form 8-K and other statements issued or made from time to time
by Magellan Health Services, Inc. or its representatives (the "Company")
contain statements which may constitute "forward-looking statements" under
the Private Securities Litigation Reform Act of 1995. Those statements
include statements regarding the intent, belief or current expectations of
Magellan and members of its management team, as well as the assumptions on
which such statements are based. Words or phrases such as "should result,"
"are expected to," "anticipate," "estimate", "project" or similar expressions
are intended to identify forward-looking statements; however, not all
forward-looking statements contain such phrases. Prospective investors are
cautioned that any such forward-looking statements are not guarantees of
future performance and involve risks and uncertainties and that actual
results may differ materially from those contemplated by such forward-looking
statements. Important factors currently known to management that could cause
actual results to differ materially from those in forward-looking statements
are set forth under the heading "Cautionary Statements" in Item 1 of
Magellan's Annual Report on Form 10-K for the fiscal year ended September 30,
2000, which information is hereby incorporated by reference in this Form 8-K.
Magellan undertakes no obligation to update or revise forward-looking
statements to reflect changed assumptions, the occurrence of unanticipated
events or changes to future operating results over time.

         On March 9, 2001, the Company consummated the sale of the stock of
National Mentor, Inc. ("Mentor"), its human services business segment, to an
entity formed by the management of Mentor and Madison Dearborn Partners, a
private equity investment firm. The Company received approximately $113
million in consideration, net of approximately $2 million of transaction
costs. The Company received approximately $103 million in cash and $10
million is in the form of interest bearing notes. In addition, the Company
has maintained certain other liabilities amounting to approximately $3
million. Approximately $50 million of the proceeds were used to retire term
loans, as required by the company's Credit Agreement, with the remainder used
to reduce amounts outstanding under its revolving facility.

    NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

     A.   ProForma adjustment to remove assets and liabilities of Mentor.

     B.   ProForma adjustment to record Mentor sale transaction. This includes
          the following: (i) receipt of $103 million of cash; (ii) retirement
          of approximately $50 million of term loans under the Company's Credit
          Agreement (iii) receipt of $10 million of 12% Subordinated Promissory
          Note; and (iv) assumption of $3 million other liabilities.

     C.   Pro Forma interest reduction resulting from the use of sale
          proceeds to reduce outstanding Term Loans and amounts outstanding
          under the Company's Revolving Facility as if the transaction was
          consummated on October 1, 1999. In the calculation of Pro Forma
          interest, the Company applied 50% of the net cash proceeds from the
          sale to the Term Loans in accordance with the terms of the
          Company's Credit Agreement. With regards to the Revolving Facility,
          the calculation of Pro Forma interest is based on the monthly
          balance outstanding under the Company's Revolving Facility up to a
          maximum balance of approximately $50 million per month which
          represents the remaining proceeds. The Company used its average
          actual quarterly borrowing rates under the Credit Agreement to
          compute the pro forma interest reduction. These rates varied between
          7.65% and 10.79%.

     D.   Pro Forma interest income is related to the $10 million 12%
          Subordinated Promissory Note the Company received in conjunction with
          the Mentor transaction as if the Company received such notes on
          October 1, 1999.

     E.   Income taxes on Pro Forma adjustments reflects the Company's combined
          Federal and State rate of approximately 40%.

     F.   The Company has accounted for the sale of Mentor under Accounting
          Principles Board Opinion No. 30, "Reporting the Results of
          Operations--Reporting the Effects of Disposal of a Segment of a
          Business, and Extraordinary, Unusual and Infrequently Occurring Events
          and Transactions" ("APB 30"). APB 30 requires that the results of
          continuing operations be reported separately from those of
          discontinued operations for all periods presented and that any gain or
          loss from disposal of a segment of a business be reported in
          conjunction with the related results of discontinued operations.
          Accordingly, the Company has restated its results of operations for
          all prior periods. The restated condensed consolidated financial
          information for the fiscal year ended September 30, 2000 is based upon
          the audited financial statements set forth in the Company's Annual
          Report filed on Form 10-K.

          The Unaudited ProForma Condensed Financial Information as of and for
          the three months ended December 31, 2000 is based upon the unaudited
          financial statements set forth in the Company's quarterly report
          filed on form 10-Q. These financial statements reflect Mentor as a
          discontinued operation in accordance with Emerging Issues Task Force
          No. 95-18 - "Accounting and Reporting for a Discontinued Business
          Segment When the Measurement Date Occurs after the Balance Sheet
          Date but before the Issuance of Financial Statements". Accordingly
          no restatement adjustment is required for the three months ended
          December 31, 2000.
