                                 April 24, 1997
 
Dear Fellow Stockholder:
 
    You are cordially invited to attend the Annual Meeting of Stockholders (the
"Annual Meeting") of Magellan Health Services, Inc. ("Magellan") on May 30,
1997, at 10:00 A.M. The Annual Meeting will be held at 191 Peachtree Street,
50th Floor, Atlanta, Georgia. A Notice of Annual Meeting, Proxy Statement and
Proxy concerning information about matters to be acted on at the Annual Meeting
are enclosed.
 
    At the Annual Meeting, in addition to the election of directors and other
routine business, you will be asked to approve a proposed transaction (the
"Crescent Transaction") between Magellan and Crescent Real Estate Equities
Company ("Crescent"). Crescent is a publicly-traded real estate investment trust
which, together with its affiliates, owns over $1.7 billion in real estate
assets.
 
    The Crescent Transaction, which I will describe below, is unique and
advantageous to Magellan and its stockholders in my opinion. Simply put, it
allows us to monetize our psychiatric hospital assets, deleverage our balance
sheet, provide funds for expansion in the highest growth segments of our company
and potentially expand the multiple of earnings on our common stock. Please read
the entire Proxy Statement for a complete discussion of the opportunities and
risks associated with the Crescent Transaction.
 
    Details of the Crescent Transaction are as follows:
 
    - We will sell to Crescent substantially all of the real property owned by
      Magellan and used in the operation of our domestic hospital provider
      operations, principally inpatient psychiatric facilities, and the
      furniture and equipment related to such facilities (the "Purchased
      Facilities").
 
    - We will receive aggregate cash consideration of $400 million (before
      transaction costs estimated to be $12.5 million) for the sale of the
      Purchased Facilities and certain information systems assets, and the
      issuance of the Magellan Warrants (described below). Assuming consummation
      of the proposed sale of the Company's European hospitals (from which the
      Company expects to realize $72.5 million net of transaction costs), and
      after repayment of indebtedness relating to the Purchased Facilities and
      indebtedness under the Company's senior credit facility, the Company
      expects to have approximately $272 million of proceeds remaining from the
      Crescent Transactions. The Company may be required to redeem some or all
      of its $375 million of 11.25% Senior Subordinated Notes.
 
    - Magellan and Crescent Operating, Inc., an affiliate of Crescent ("COI"),
      will create Charter Behavioral Health Systems, LLC ("CBHS"), which will
      operate Magellan's domestic hospital provider business after the closing
      of the Crescent Transaction. CBHS will be owned equally by Magellan and
      COI, with the ability of the CBHS board to grant up to a 10%-equity
      interest to CBHS management in the future.
 
    - Crescent will lease the Purchased Facilities to CBHS. The initial lease
      term is 12 years with CBHS paying rent to Crescent, which will initially
      be $40 million annually and increasing 5% compounded annually.
 
    - Magellan will retain all intellectual property relating to the Facilities,
      including the "CHARTER" name, services and treatment protocols, which CBHS
      will be allowed to utilize in exchange for the payment of annual franchise
      fees to Magellan. The franchise agreement will have an initial term of 12
      years and will provide for fees of $81 million per year, subject to
      increase. The franchise fees due Magellan will be subordinated in payment
      to the rent due Crescent. Therefore, if CBHS encounters a decline in
      earnings or financial difficulties, it is possible that cash flow from
      CBHS' operations will not be sufficient to pay the franchise fees when
      due.
    - Magellan will issue warrants (the "Magellan Warrants") to Crescent and
      COI, which give Crescent and COI each the right to purchase up to
      1,283,311 shares of Magellan common stock at an exercise price of $30 per
      share.

    - COI will issue warrants to Magellan, which give Magellan the right to
      purchase up to 2.5% of the common stock of COI.
 
    AFTER CAREFUL CONSIDERATION, YOUR BOARD OF DIRECTORS (EXCEPT FOR DARLA D.
MOORE, WHO DID NOT PARTICIPATE DUE TO HER BENEFICIAL OWNERSHIP OF CRESCENT)
UNANIMOUSLY APPROVED THE CRESCENT TRANSACTION AND RECOMMENDS THAT STOCKHOLDERS
VOTE FOR THE CRESCENT TRANSACTION. In considering the Crescent Transaction, the
Board of Directors relied, in part, on the opinion of its financial advisor,
Dean Witter Reynolds Inc., to the effect that the consideration to be received
in the Crescent Transaction is fair, from a financial point of view, to
Magellan. A copy of the fairness opinion is attached as an appendix to the Proxy
Statement.
 
    I encourage you to attend the Annual Meeting. The affirmative vote of
holders of a majority of Magellan's outstanding common stock is necessary to
approve the Crescent Transaction; provided that the shares of common stock owned
by certain affiliates of Crescent (the "Rainwater Group") will be voted in the
same percentage as shares voted by all stockholders other than the Rainwater
Group. Under this standard, the Crescent Transactions will be approved only if
the votes cast by stockholders (other than the Rainwater Group) in favor of the
Crescent Transactions exceed the votes cast by stockholders (other than the
Rainwater Group) against the Crescent Transactions.
 
    I look forward to seeing you at the Annual Meeting. REGARDLESS OF WHETHER OR
NOT YOU PLAN TO ATTEND THE ANNUAL MEETING, PLEASE COMPLETE, SIGN AND DATE THE
ENCLOSED PROXY CARD AND RETURN IT IN THE ENCLOSED ENVELOPE. This will ensure
that sufficient shares are represented and voted at the Annual Meeting.
Returning your completed proxy card will not limit your right to vote in person
if you attend the Annual Meeting.
 
    If you have any questions regarding the Crescent Transaction, please call
Kevin Helmintoller, Senior Director of Investor Relations, at (404) 814-5742.
 
                                          Very truly yours,
 
                                          /s/ MAC CRAWFORD

that COI will have a right to be the lessee of all hotel and any similar
properties developed by Crescent that must be leased to preserve CEI's status as
a REIT. COI initially will have the same executive officers as Crescent. The
principal executive office of COI will be located at 777 Main Street, Suite
2100, Fort Worth, Texas 76102, telephone number (817) 887-0477.
 
    CBHS.  CBHS will be a Delaware limited liability company, initially owned
equally by Magellan and COI, which is being created to effect the Crescent
Transactions. CBHS initially will have no operations except those contemplated
by the Crescent Transactions. The principal executive office of CBHS will be
located at 3414 Peachtree Road, N.E., Suite 900, Atlanta, Georgia 30326,
telephone number (404) 814-0800.

ANNUAL MEETING
 
    At the Annual Meeting, the holders of Common Stock will be asked to
consider:
 
    1. A proposal to elect three directors to three-year terms expiring at the
       2000 annual meeting of stockholders;
 
    2. A proposal to approve the Certificate Amendment;
 
    3. A proposal to approve the 1997 Plan;
 
    4. A proposal to approve and adopt the Crescent Transactions; and
 
    5. Such other matters as may properly come before the Annual Meeting.
 
    The Annual Meeting will be held at 191 Peachtree Street, 50th floor,
Atlanta, Georgia on May 30, 1997, at 10:00 A.M. local time. The Board has fixed
the close of business on April 11, 1997, as the record date for determining the
holders of Common Stock entitled to notice of, and to vote at, the Annual
Meeting. There are no rights of appraisal or similar dissenters' rights with
respect to any matter to be acted upon pursuant to this Proxy Statement.
 
VOTE REQUIRED
 
    The Certificate of Incorporation, By-laws and applicable law provide that:
(i) a plurality of the votes cast at the Annual Meeting is required to elect the
nominees as directors; (ii) the affirmative vote of 75% of the outstanding
Common Stock is required to approve the Certificate Amendment; (iii) the
affirmative vote of a majority of the Common Stock represented at the Annual
Meeting is necessary to approve the 1997 Plan; and (iv) the affirmative vote of
a majority of the outstanding Common Stock is required to approve the Crescent
Transactions.
 
    With respect to the Crescent Transactions, shares of outstanding Common
Stock owned by the Rainwater Group (approximately 3,885,832 shares, or 13.5% of
the outstanding Common Stock as of the record date) will be voted in the same
percentage as the shares of outstanding Common Stock voted by all stockholders
other than the Rainwater Group (approximately 24,920,349 million shares, or
86.5% of the outstanding Common Stock as of the record date). Under this
standard, the Crescent Transactions will only be approved if the votes cast by
stockholders (other than the Rainwater Group) in favor of the Crescent
Transactions exceed the votes cast by stockholders (other than the Rainwater
Group) against the Crescent Transactions. On the record date, there were
28,806,181 shares of Common Stock outstanding and entitled to vote.
 
    Magellan's proposed sale of 3 European hospitals does not require
stockholder approval, and none is being sought.
 
RECOMMENDATIONS OF THE BOARD
 
    THE BOARD HAS UNANIMOUSLY APPROVED THE NOMINEES FOR ELECTION AS DIRECTORS,
THE CERTIFICATE AMENDMENT AND THE 1997 PLAN, AND RECOMMENDS THAT STOCKHOLDERS

CRESCENT TRANSACTIONS
 
    The Crescent Transactions provide for the following:
 
    - Magellan will sell to Crescent the Purchased Facilities and substantially
      all of the fixtures, furniture and equipment owned by Charter and used in
      the Facilities for $395 million. The Purchased Facilities include 83
      behavioral healthcare facilities and related medical office buildings.
 
    - Magellan and COI will form CBHS, which will operate the Charter business
      after the Closing. CBHS initially will be owned equally by the Company and
      COI, with the ability of the CBHS board to grant up to a 10%-equity
      interest to CBHS management in the future.
 
    - Magellan will contribute to CBHS certain property and intangible rights
      used in connection with the Facilities in exchange for the CBHS Interest.
      The property that will be contributed to CBHS includes interests in five
      acute care psychiatric hospitals and other ancillary facilities that
      Magellan currently leases from third parties. CBHS will also purchase
      certain assets from Magellan relating to the Company's information systems
      subsidiary for $5 million.
    - Magellan will receive aggregate cash consideration of $400 million (before
      costs estimated to be $12.5 million) from the sale of the Purchased
      Facilities to Crescent, the issuance of the Warrants and the sale of
      assets to CBHS. Assuming consummation of the proposed sale of the
      Company's European hospitals (from which the Company expects to realize
      $72.5 million net of transaction costs), and after repayment of industrial
      revenue bond indebtedness relating to the Purchased Facilities and
      indebtedness under the Company's Revolving Credit Agreement, the Company
      expects to have approximately $272 million of proceeds remaining from the
      Crescent Transactions.
 
    - Magellan will enter into a services agreement with CBHS pursuant to which
      CBHS will manage Magellan's interest in certain joint ventures with
      unaffiliated third parties, including joint ventures that operate or
      manage ten acute behavioral healthcare facilities. Magellan is the general
      partner or managing entity of each such joint venture.
 
    - Crescent will lease the Purchased Facilities to CBHS under a 12-year lease
      (subject to renewal). CBHS will pay annual base rent to Crescent, which
      will initially be $40 million and increase at 5% compounded annually.
 
    - CBHS will operate the Facilities under the "CHARTER" name, services and
      protocols, and pay Franchise Fees to Magellan. The Franchise Fees will
      initially be $81 million, subject to increase. The Franchise Fees due
      Magellan will be subordinated in payment to the base rent, minimum
      escalator rent and a specified portion of additional rent due Crescent. If
      CBHS encounters a decline in earnings or financial difficulties, it is
      possible that cash flow from CBHS' operations will not be sufficient to
      pay the Franchise Fees when due.
 
    - Magellan will issue to Crescent and COI the Warrants, which are
      exercisable at various times over the next 12 years and give Crescent and
      COI each the right to purchase up to 1,283,311 shares of Common Stock at
      an exercise price of $30 per share. The 2,566,622 shares of Common Stock
      underlying the Warrants would have represented approximately 8.2% of
      Magellan's outstanding Common Stock if exercised as of the record date.
 
    - COI will issue to Magellan the COI Warrants, which are exercisable at
      various times over the next 12 years and give Magellan the right to
      purchase up to 2.5% of the common stock of COI outstanding at the Closing.
      The COI Warrants are exercisable only at the times, and in the
      proportions, that Crescent or COI exercises the Warrants. The exercise
      price for the COI Warrants will reflect the same premium as used to
      calculate the exercise price of the Warrants, based upon a valuation of
      COI to be conducted by a mutually agreed upon independent appraiser once a
      trading market for COI common stock has been established.
 
                                       3
<PAGE>
    - At the Closing, Magellan will either (i) provide CBHS with bridge
      financing for a one-year term in the maximum amount of $55 million,
      secured by CBHS' receivables, to fund CBHS' anticipated working capital
      needs during its first year of operation or (ii) provide a guarantee under
      certain circumstances, not to exceed $65 million, for a CBHS bank line of
      credit secured by CBHS' receivables. CBHS has received a loan commitment
      from a group of commercial banks to provide a line of credit of up to $100
      million pursuant to a 5-year revolving credit facility.
 
    - Both the Company and COI will contribute an additional $2.5 million in
      cash to the capital of CBHS within five days after Closing. In addition,
      each of the Company and COI will make a commitment to loan CBHS up to
      $17.5 million each, for a period of five years. The Company will have the
      right to require CBHS to draw down a portion of its loan commitment, which
      will be funded equally by the Company and COI, and will be used in the
      manner directed by the Company.
 
    See "Crescent Transactions--The Transactions."
 
THE WARRANTS
    As part of the Crescent Transactions, Magellan will issue the Warrants to
each of Crescent and COI. The aggregate purchase price for the Warrants is
included in the consideration to be paid by Crescent under the Crescent Purchase
Agreement. Magellan has valued the Warrants at $25 million. The issuance of the
Warrants is an integral part of the Crescent Transactions and is intended to
align the economic interests of Crescent and COI, with those of Magellan. The
issuance of the Warrants will have no immediate impact on the rights of existing
Magellan stockholders. Any exercises of the Warrants will dilute the voting
rights of existing Magellan stockholders. The Warrants are exercisable at
various times over the 12 year period after the Closing and give Crescent and
COI each the right to purchase up to 1,283,311 shares of Common Stock at an
exercise price of $30 per share.
 
    See "Crescent Transactions--The Warrants."
 
BACKGROUND
 
    For description of the background of the Crescent Transactions, see
"Crescent Transactions-- Background."
 
DECISION TO ENGAGE IN THE CRESCENT TRANSACTIONS
    The Board considered the following factors in its evaluation of the Crescent
Transactions:
 
    - The receipt by the Company of $400 million in cash (before costs estimated
      at $12.5 million) and the COI Warrants. The Company anticipates that the
      cash it receives will allow it to pursue acquisitions in the managed care,
      public sector and related information services segments, develop new
      products, increase managed care and public sector marketing efforts, and
      reduce debt.
 
    - The ability of CBHS to pay the Franchise Fees. Based on the historical
      operating results of Charter, the Board believes that Magellan's results
      of operations will not be adversely impacted as a result of the Crescent
      Transactions.
 
    - The right of the Noteholders, after the Closing, to have the Company
      repurchase their Notes at a purchase price equal to 101% of the aggregate
      principal amount of the Notes, plus accrued and unpaid interest. Such a
      repurchase could impede or delay the Company's acquisition and product
      development strategies. The Board believes that it is unlikely that the
      Company will be required to repurchase all of the Notes because the recent
      bid and asked prices of the Notes on the New York Stock Exchange have been
      higher than the price at which the Company would be required to repurchase
      the Notes. Moreover, in the event that the Company is required to
      repurchase some or all of the Notes, the Board believes the Company could
      use the net proceeds from the Crescent
 
                                       4
<PAGE>
      Transactions and additional borrowings under its new credit agreement to
      finance the repurchase of the Notes and significantly reduce the Company's
      interest expense and improve its capital structure.
 
    - The removal of substantially all of the net assets and results of
      operations of the Facilities from the Company's financial statements. The
      Company believes that this will enhance its stock market valuation, which
      may enhance the Company's ability to pursue acquisitions.
 
    - The ability of CBHS to accelerate its acquisition strategy and lead the
      consolidation of the provider segment of the behavioral healthcare
      industry. CBHS seeks to increase provider capability, both on an inpatient
      and outpatient basis, through an aggressive program of acquisitions and
      joint ventures. Through the Crescent transactions, CBHS will have access
      to Crescent's financing and real estate expertise to enhance CBHS' ability
      to capitalize on opportunities for growth. Such acquisitions and joint
      ventures could, individually or in the aggregate, be material to CBHS (and
      indirectly to Magellan). As an owner of CBHS, Magellan has the right to
      participate in the approval of any significant acquisition or joint
      venture by CBHS.
 
    - The fairness opinion of Dean Witter, to the effect that the consideration
      to be received in the Crescent Transactions is fair, from a financial
      point of view, to the Company.
    - The rent payments under the Facilities Lease represent a higher cost of
      capital than certain traditional financing alternatives. However, the
      Board views the Crescent Transactions primarily as a strategic realignment
      of the Company and believes that the consideration received from the
      Crescent Transactions, the removal of the net assets and results of
      operations of the Facilities from the Company's financial statements, and
      the Company's retention of the "CHARTER" name and other intangible rights
      relating to its hospital provider business substantially outweigh the high
      cost of capital implied by the rent payments under the Facilities Lease.
 
    - The Company's loss of operating control over the Facilities. After the
      Closing, the Facilities will be operated by CBHS and the Company will not
      be able to control CBHS. However, the Company will have the right to
      designate one-half of the members of the CBHS board. Therefore, the Board
      does not view the loss of control as a significant disadvantage because of
      the continuity of the management team, with whom it is familiar and the
      Company's representation on the CBHS board.
 
    - The Company's retention of the "CHARTER" name and other valuable
     intangible rights relating to its hospital provider business, which will
     allow the Company to continue receiving revenues from these assets. During
     the term of the Master Franchise Agreement, the Company will have the right
     to receive Franchise Fees, which initially will be $81 million annually.
     After the Closing, the Company will be able to pursue opportunities to
     franchise the "CHARTER" name, services and protocols to companies other
     than CBHS.
 
    See "Crescent Transactions--Decision to Engage in the Crescent
Transactions."
 
OPINION OF FINANCIAL ADVISOR
 
    Dean Witter rendered its opinion to the effect that the consideration to be
received in the Crescent Transactions was fair, from a financial point of view,
to the Company.
 
    The full text of the opinion of Dean Witter, dated January 29, 1997, is
attached as Appendix I. Stockholders are urged to read the opinion in its
entirety for a description of the factors considered and assumptions made by
Dean Witter in rendering its opinion.

RISK FACTORS
 
    Certain factors that stockholders should consider when deciding how to vote
on the Crescent Transactions are discussed below. These factors, individually or
in the aggregate, could have a material adverse effect on the Company.
 
    LOSS OF CONTROL OF THE FACILITIES AND CBHS.  After the Closing, the
Facilities will be operated by CBHS and the Company will not be able to control
CBHS. Magellan's operational input in CBHS will be limited to those rights
provided by the franchise agreements and the CBHS Operating Agreement. For a
more detailed discussion of how CBHS will operate the Facilities under the
franchise agreements, see "Crescent Transactions--Subsidiary Franchise
Agreement." See also "Crescent Transactions--Master Franchise Agreement" and
"--CBHS Operating Agreement."
 
    SUBORDINATION OF PAYMENT OF FRANCHISE FEES.  As part of the Crescent
Transactions, CBHS will lease the Purchased Facilities from Crescent under the
Facilities Lease. See "Crescent Transactions--Facilities Lease." The annual base
rent under the Facilities Lease begins at $40 million and increases at 5% per
year, compounded annually. The Subordination Agreement provides that the
Franchise Fees are subordinated in payment to the $40 million annual base rent,
5% minimum escalator rent and, in certain circumstances, specified portions of
the additional rent due Crescent under the Facilities Lease. (See "Crescent
Transactions--Subordination Agreement"). If CBHS encounters a decline in
earnings or financial difficulties, such amounts due Crescent will be paid
before any Franchise Fees are paid. The remainder of CBHS' available cash will
then be applied in such order of priority as CBHS may determine, in the
reasonable discretion of the CBHS board, to all other operating expenses of
CBHS, including the current and accumulated Franchise Fees. The Company will be
entitled to pursue all available remedies for breach of the Master Franchise
Agreement, except that the Company does not have the right to take any action
that could reasonably be expected to force CBHS into bankruptcy or receivership.
 
    VOLATILITY OF EARNINGS.  The Company will use the proceeds of the Crescent
Transactions to reduce net interest expense by repaying long-term debt where
possible and investing the remaining proceeds in short-term cash equivalents
pending redeployment. Although the Company's net interest expense will be lower,
the Company's reduced earnings from Charter from the Crescent Transactions could
be even more pronounced. Until Noteholders decide whether or not to sell their
Notes (see "--Risk Factors, Indenture"), the Company will not have flexibility
to allocate its capital resources. Once the Noteholders decide whether or not to
sell their Notes to the Company, capital resource decisions (e.g., acquisitions)
may take time to implement. Such a repurchase could impede or delay the
Company's acquisition and product development strategies.
 
    The Company derived approximately $809 million, or 60%, of its fiscal 1996
revenue from the Facilities. The Crescent Transactions could reduce the
Company's earnings in the short-term until the net proceeds from the Crescent
Transactions are deployed by the Company. There can be no assurance that the
Company's use of the net proceeds from the Crescent Transactions will increase
the Company's long-term earnings. Although CBHS intends to aggressively grow its
business through acquisitions and joint ventures, there can be no assurance such
acquisitions and joint ventures will not result in an adverse effect on CBHS'
balance sheet, earnings, cash flow or competitive position, or that any
acquisitions or joint ventures will be consummated. In addition, if CBHS
encounters a decline in earnings or financial difficulties, it is possible that
cash flow from CBHS' operations will not be sufficient to pay the Franchise Fees
when due.
 
    LOSS INCURRED AS A RESULT OF THE CRESCENT TRANSACTIONS.  The Company expects
to record a loss before income taxes and extraordinary items related to the
Crescent Transactions. On a pro forma basis at December 31, 1996, the loss
before income taxes and extraordinary items to be incurred as a result of the
Crescent Transactions would have been approximately $57.0 million, which
includes accounts receivable collection fees ($18.0 million), impairment losses
on hospital-based goodwill and other intangible assets ($15.6 million), exit
costs and related commitments ($15.5 million) and loss on sale of property and
equipment ($7.9 million).
 
                                       6
<PAGE>
    NET OPERATING LOSS CARRYFORWARDS.  As of September 30, 1996, the Company
estimated that it had $250 million of NOLs. The Company expects to use a
substantial portion of the NOLs to offset taxable income from fiscal 1997,
including taxable gain from the European Sale. The Company expects to sell the
European hospitals in May 1997 for approximately $72.5 million, net of
transaction costs, which will result in a taxable gain to the Company of
approximately $60 million. The Company is currently being (or expects to be)
audited by the IRS for fiscal years 1989 through 1996. All or a portion of the
NOLs may be disallowed by the IRS. Therefore, the NOLs available to offset any
taxable gain recognized on the Crescent Transactions may be substantially
reduced or eliminated. Any remaining NOLs will expire between 2006 and 2010.
 
    NOLs can be used by the Company under certain circumstances to reduce or
eliminate its future federal income tax liability. However, the Code under
certain circumstances eliminates or significantly limits the use of NOLs by a
Loss Corporation that has undergone an Ownership Change. If the Company has an
Ownership Change, the taxable income that the Company can offset with NOLs in
any fiscal year is limited to the value of the Company (excluding nonbusiness
assets if the value of such assets exceeds one-third of total assets) prior to
such Ownership Change multiplied by the federal long-term tax exempt interest
rate. NOLs may be eliminated completely if the Company, after an Ownership
Change, does not continue its historic business nor use a significant portion of
its historic business assets in a new business. These rules are extremely
complex. The application of these rules to the Company depends on facts and
circumstances not known by the Company or beyond the Company's control, or which
encompass future transactions which may or may not be consummated.
 
    The Company does not believe that an Ownership Change has occurred or that
the Crescent Transactions will cause an Ownership Change. However, there can be
no assurance that unrelated transactions, regardless of whether combined with
the Crescent Transactions, will not cause an Ownership Change.
 
    GOVERNMENT REGULATION.  The Company is subject to federal and state laws
governing financial arrangements between healthcare providers. These laws
generally prohibit certain direct and indirect payments and/or fee-splitting
arrangements between healthcare providers that are designed to induce, are in
exchange for, or encourage patient referrals. The Medicare Law Amendments are
among the most prominent of such laws.
 
    The Medicare Law Amendments prohibit the offering, paying, soliciting or
receiving any form of remuneration in return for referring federal healthcare
patients, or in return for purchasing, leasing, ordering, or arranging for, or
recommending purchasing, leasing or ordering any good, facility, service or item
for which payment may be made under federal healthcare programs. Violations of
the Medicare Law Amendments may result in criminal and civil sanctions,
including exclusion from the Medicare and/or Medicaid programs.
 
    After the Crescent Transactions, the Company will receive from CBHS fixed
Franchise Fees of $81 million, which may increase in certain circumstances (See
"Crescent Transactions--Master Franchise Agreement"). The Company will provide
CBHS with an array of services, including advertising and marketing assistance,
risk management services, outcomes monitoring, consultation with respect to
matters relating to CBHS' business in which the Company has expertise and the
Company's operation of a telephone call center utilizing the "1-800-CHARTER"
telephone number. The Company believes that the Franchise Fee arrangements
described above are consistent with the Medicare Law Amendments because such
arrangements do not involve the Company's referral of patients to CBHS. However,
there can be no assurance that regulatory agencies or private parties will not
challenge the Company based on alleged violations of the Medicare Law
Amendments.
 
    INDENTURE.  After the Closing, Noteholders will have the right to require
the Company to repurchase their Notes at a purchase price equal to 101% of the
principal amount of the Notes, plus accrued and unpaid interest. Noteholders
will have until a deadline specified by the Company, which can be up to 70 days
after the Closing, to make the necessary election. If all Noteholders elect to
exercise the
 
                                       7
<PAGE>
repurchase rights described above, the cost to the Company will be approximately
$378.8 million plus accrued and unpaid interest. The Noteholders include Huff,
which owns approximately 35% of the Notes, and other institutional investors.
The Noteholders acquired $375 million of the Company's notes in a private
placement in 1994 followed by an exchange offering pursuant to which such notes
were exchanged for the Notes, which were registered under the Securities Act of
1933, as amended, and listed for public trading.
 
    The Company has received a commitment letter from two commercial banks,
which provides a commitment to lend to the Company up to $200 million to
repurchase the Notes. The Company believes that it will have sufficient
liquidity from the proceeds of the Crescent Transactions, internal cash reserves
and anticipated borrowing capacity under the new credit agreement to repurchase
all of the Notes that it could be required to repurchase.
 
    See "Crescent Transactions--Risk Factors."
 
INTERESTS OF CERTAIN PERSONS IN THE CRESCENT TRANSACTIONS AND THE 1997 PLAN
 
    Richard E. Rainwater and his affiliates and associates have a significant
interest in the Crescent Transactions.
 
    CRESCENT.  Crescent is the operating partnership of CEI. The officers of CEI
include Richard E. Rainwater, Chairman of the Board of Directors, John C. Goff,
Vice Chairman, and Gerald W. Haddock, President and Chief Executive Officer. The
sole general partner of Crescent is Crescent GP, which is a wholly-owned
subsidiary of CEI. Mr. Haddock is the sole director of Crescent GP. The persons
who are executive officers of CEI hold the same offices in Crescent GP, except
that Messrs. Rainwater and Goff are not directors or officers of Crescent GP.
Messrs. Rainwater, Goff and Haddock own beneficially 17.3%, 2.0% and 1.3% of
Crescent, respectively, which interests consist of common stock in CEI
(including common stock of CEI that may be acquired pursuant to the exercise of
options) and units of ownership in Crescent. Following the Crescent
Transactions, Mr. Goff will become Chairman of CBHS. Mr. Rainwater is an
affiliate of Crescent, Crescent GP and CEI.
 
    RAINWATER-MAGELLAN HOLDINGS, L.P.  Rainwater-Magellan owns 3,885,832 shares
of Common Stock and holds the Rainwater-Magellan Warrant, which gives
Rainwater-Magellan the right to purchase up to an additional 1,942,996 shares of
Common Stock. These securities were acquired by Rainwater-Magellan from the
Company in the Private Placement. Rainwater, Inc. is the sole general partner of
Rainwater-Magellan. Richard E. Rainwater is the sole stockholder of Rainwater,
Inc. Mr. Rainwater has sole voting and dispositive power over the shares of
Common Stock owned by Rainwater-Magellan and the shares of Common Stock that can
be purchased upon exercise of the Rainwater-Magellan Warrant. As a result of
such relationships, Mr. Rainwater is deemed to be the beneficial owner of the
shares of Common Stock held by Rainwater-Magellan, including the shares of
Common Stock that underlie the Rainwater-Magellan Warrant.
 
    Messrs. Rainwater, Goff and Haddock own approximately 61.9%, 1.4% and 1.4%
of Rainwater-Magellan, respectively. Mr. Rainwater's three children own
beneficially an additional 4.6% of Rainwater-Magellan through a limited
partnership of which Mr. Rainwater is general partner and an additional 1.1%
each through trusts that are managed by an unaffiliated trustee.
 
    Darla D. Moore, a director of the Company, is the spouse of Richard E.
Rainwater. Under the terms of the Private Placement Agreements,
Rainwater-Magellan has the right to designate a nominee acceptable to the
Company for election as a director as long as the Rainwater Group owns
beneficially a specified minimum number of shares of Common Stock.
Rainwater-Magellan proposed Ms. Moore as its nominee for director, and Ms. Moore
was elected a director in February, 1996. Because of her relationship to Mr.
Rainwater and the Rainwater Group, Ms. Moore has not participated in any Board
action taken with respect to the Crescent Transactions. For purposes of this
Proxy Statement, any reference to the "Rainwater Group" includes
Rainwater-Magellan, Rainwater, Inc., Richard E. Rainwater, Darla D. Moore and
their affiliates and associates. See "Crescent Transactions--Interested
Parties."

    E. MAC CRAWFORD.  Under the Company's Employment Agreement with Mr.
Crawford, its Chairman of the Board, President and Chief Executive Officer, Mr.
Crawford will be paid a contract bonus in the amount of $2.475 million if the
Crescent Transactions are closed. In addition, Mr. Crawford has received a grant
under the 1997 Plan, subject to stockholder approval, for the purchase of
750,000 shares of Common Stock. Under the terms of Mr. Crawford's Employment
Agreement with the Company, if stockholders do not approve the 1997 Plan by
September 1, 1997, Mr. Crawford will be entitled to resign at any time before
the end of the agreement's term and receive, in addition to accrued salary and
bonus and benefits, a payment five times Mr. Crawford's annual salary (such
payment would currently be $4.125 million), subject to a gross-up for certain
excise taxes. See "Compensation Committee Report on Executive
Compensation--Employment Agreements and Change of Control Provisions."
 
    CERTAIN EMPLOYEES.  Each of the Named Executive Officers and certain other
officers and key employees of the Company and its subsidiaries have been awarded
options under the 1996 Stock Option Plan. The 1996 Plan provides that the
options granted thereunder vest and become exercisable over four years from the
date of grant, except that upon the occurrence of certain events the options
immediately vest and become fully exercisable. One such event is the "sale,
lease, transfer or other disposition . . . of all or substantially all" of the
Company's assets. Based upon a review of relevant Delaware case law, the Company
believes that substantial uncertainty exists regarding whether the Crescent
Transactions constitute a "sale . . . of all or substantially all" of the
Company's assets. Accordingly, the Board has determined to treat the Closing as
such an event in order to eliminate the risk of a dispute. Therefore, a total of
1,210,375 options granted under the 1996 Plan will immediately vest as a result
of the Closing. The persons who hold such options and the number of such options
held by such persons are as follows: Messrs. Crawford (225,000 options);
McKnight (68,750 options); Davis (130,000 options); Harbin (75,000 options) and
all others (711,625 options). See "Compensation Committee Report on Executive
Compensation--Employment Agreements and Change of Control Provisions."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    United States stockholders of the Company will not realize any federal
income tax consequences as a result of the Closing. The Company will recognize
gain or loss on the sale of the Purchased Facilities. To the extent gain is
recognized by the Company, the NOLs may not be available to offset such gain
(see "Crescent Transactions--Risk Factors, Net Operating Loss Carryforwards").
The Company's contribution of assets to CBHS (and the assumption of certain
liabilities by CBHS) in exchange for the CBHS Interest is anticipated to be a
tax-free exchange for federal income tax purposes. See "Crescent Transactions--
Certain Federal Income Tax Consequences."
 
ACCOUNTING TREATMENT
 
    The Crescent Transactions will result in (i) a sale of assets by the Company
to Crescent and CBHS, (ii) the deconsolidation of the Charter net assets and
operating results from the Company's financial statements and (iii) the
Company's contribution of certain assets to CBHS and the assumption of certain
liabilities by CBHS in exchange for the CBHS Interest. Any loss recognized by
the Company as a result of the Crescent Transactions will be included in the
Company's consolidated financial statements as part of continuing operations for
the period during which the Crescent Transactions are consummated. Any portion
of the Company's loss relating to the early extinguishment of debt, including
any Notes repurchased, will be classified as an extraordinary item for financial
reporting purposes. The Company's investment in CBHS will be accounted for under
the equity method of accounting. See "Crescent Transactions--Accounting
Treatment."

Warrant Purchase Agreement". A complete copy of each Crescent Transaction
Document has been filed with the SEC and is available to stockholders. See
"Incorporation of Certain Information by Reference."
 
GOVERNMENTAL AND REGULATORY APPROVALS
 
    The Company, Crescent and CBHS will be required to notify federal and state
governmental authorities of the Crescent Transactions and apply for new licenses
and permits. The Company believes that it, Crescent and CBHS will be able to
obtain such licenses upon application in the ordinary course of business.
 
SELECTED FINANCIAL DATA
 
    The following tables set forth selected historical and pro forma financial
information of the Company for each of the five fiscal years in the period ended
September 30, 1996 and for the three months ended December 31, 1995 and 1996.
The information prior to August 1992 is not comparable because of the
consummation of the Plan and the implementation of fresh start accounting in
fiscal 1992, which included the revaluation of the Company's assets and
liabilities and resulted in, among other things, significant reductions in
long-term debt and interest expense and elimination of preferred stock and
preferred stock dividend requirements. In 1993, the Company restated its
consolidated financial statements to reflect the sale of certain subsidiaries as
discontinued operations. The Historical Summary of Operations and Balance Sheet
Data for the five fiscal years in the period ended September 30, 1996, presented
below, has been derived from, and should be read in conjunction with "Item 1.
Business", "Item 7. Management's Discussion and Analysis of Financial Condition
and Results of Operations" and the Consolidated Financial Statements of the
Company included in the Company's Annual Report on Form 10-K, as amended, for
the fiscal year ended September 30, 1996, which is incorporated herein by
reference. The Historical Summary of Operations for the three months ended
December 31, 1995 and 1996 and Balance Sheet Data as of December 31, 1996 has
been derived from and should be read in conjunction with the Condensed
Consolidated Financial Statements and Management's Discussion and Analysis of
Financial Condition and Results of Operations of the Company included in the
Company's Quarterly Report on Form 10-Q for the quarterly period ended December
31, 1996, which is incorporated herein by reference.
 
    The Unaudited Pro Forma Consolidated Financial Statements are presented
using two different assumptions. Under the terms of the Indenture, Noteholders
may elect to have the Company repurchase their Notes at 101% of the face value
of the Notes after the Closing. The first presentation assumes that no
Noteholders elect to have their Notes repurchased, with the net proceeds from
the Crescent Transactions, after payment of indebtedness outstanding under the
Revolving Credit Agreement and other long-term debt, held on deposit with no
investment return. If the excess proceeds from the Crescent Transactions were
assumed to be invested at Magellan's historic temporary cash investment rate of
5.4% for the year ended September 30, 1996 and 5.25% for the three months ended
December 31, 1996, pro forma consolidated net income and net income per common
share would be $24.5 million and $0.86, respectively, for the year ended
September 30, 1996 and $9.5 million and $0.33, respectively, for the three
months ended December 31, 1996. The second presentation assumes that all
Noteholders elect to have their Notes repurchased by the Company and no net
proceeds from the Crescent Transactions available for deposit. On January 29,
1997, the date preceding public announcement of the Crescent Transactions, the
bid and asked prices of the Notes on the New York Stock Exchange were 110.75%
and 111.25% of the face value of the Notes, respectively. On April 17, 1997, the
bid and asked prices of the Notes on the New York Stock Exchange were 107% and
112% of the face value of the Notes, respectively.
 
    The Pro Forma Summary of Operations for the fiscal year ended as of
September 30, 1996 and the three months ended December 31, 1996, and the Pro
Forma Balance Sheet Data as of December 31, 1996 have been derived from, and
should be read in conjunction with, the Unaudited Pro Forma Consolidated
Financial Information, which is included elsewhere in this Proxy Statement and
is incorporated herein by reference.

                            PROXY STATEMENT FOR THE
                      1997 ANNUAL MEETING OF STOCKHOLDERS
 
                             ---------------------
 
                               THE ANNUAL MEETING
 
    This Proxy Statement is being furnished in connection with the solicitation
of proxies by the Board from the holders of Common Stock, for use at the Annual
Meeting to be held at 10:00 A.M., local time, on May 30, 1997, and any
adjournment or postponement thereof. The Annual Meeting will be held at 191
Peachtree Street, 50th Floor, Atlanta, Georgia. This Proxy Statement and the
accompanying form of proxy are first being sent or given to stockholders on or
about April 24, 1997. At the Annual Meeting, stockholders will be asked to
consider and vote upon:
 
        1.  A proposal to elect three (3) directors for three-year terms
    expiring at the 2000 annual meeting of stockholders or until their
    successors are duly elected and qualified;
 
        2.  A proposal to approve the Certificate Amendment, which will increase
    the number of directors from 8 to 12;
 
        3.  A proposal to approve the 1997 Plan;
 
        4.  A proposal to approve the Crescent Transactions, which provide for
    the following:
 
       - Magellan will sell to Crescent the Purchased Facilities and
         substantially all of the fixtures, furniture and equipment owned by
         Charter and used in the Facilities for $395 million. The Purchased
         Facilities include 83 behavioral healthcare facilities and related
         medical office buildings.
 
       - Magellan and COI will form CBHS, which will operate the Charter
         business after the Closing. CBHS initially will be owned equally by the
         Company and COI, with the ability of the CBHS board to grant up to a
         10%-equity interest to CBHS management in the future.
 
       - Magellan will contribute to CBHS certain property and intangible rights
         used in connection with the Facilities in exchange for the CBHS
         Interest. The property that will be contributed to CBHS includes
         interests in five acute care psychiatric hospitals and other ancillary
         facilities that Magellan currently leases from third parties. CBHS will
         also purchase certain assets from Magellan relating to the Company's
         information systems subsidiary for $5 million.
       - Magellan will receive aggregate cash of $400 million (before costs
         estimated to be $12.5 million) from the sale of the Purchased
         Facilities to Crescent, the issuance of the Warrants and the sale of
         assets to CBHS. Assuming consummation of the possible sale of the
         Company's European hospitals (from which the Company expects to realize
         $72.5 million net of transaction costs), and after repayment of
         industrial revenue bond indebtedness relating to the Purchased
         Facilities and indebtedness under the Company's Revolving Credit
         Agreement, the Company expects to have approximately $272 million of
         proceeds remaining from the Crescent Transactions.
 
                                       14
<PAGE>
       - Magellan will enter into a services agreement with CBHS pursuant to
         which CBHS will manage Magellan's interest in certain joint ventures
         with unaffiliated third parties, including joint ventures that operate
         or manage ten acute behavioral healthcare facilities. Magellan is the
         general partner or managing entity of each such joint venture.
 
       - Crescent will lease the Purchased Facilities to CBHS under a 12-year
         lease (subject to renewal). CBHS will pay annual base rent to Crescent,
         which will initially be $40 million and increase at 5% compounded
         annually.
 
       - CBHS will operate the Facilities under the "CHARTER" name, services and
         protocols, and pay Franchise Fees to Magellan. The Franchise Fees will
         initially be $81 million, subject to increase. The Franchise Fees due
         Magellan will be subordinated in payment to the base rent, minimum
         escalator rent and a specified portion of additional rent due Crescent.
         If CBHS encounters a decline in earnings or financial difficulties, it
         is possible that cash flow from CBHS' operations will not be sufficient
         to pay the Franchise Fees when due.
 
       - Magellan will issue to Crescent and COI the Warrants, which are
         exercisable at various times over the next 12 years and give Crescent
         and COI each the right to purchase up to 1,283,311 shares of Common
         Stock at an exercise price of $30 per share. The 2,566,622 shares of
         Common Stock underlying the Warrants would have represented
         approximately 8.2% of Magellan's outstanding Common Stock if exercised
         as of the record date.
 
       - COI will issue to Magellan the COI Warrants, which are exercisable at
         various times over the next 12 years and give Magellan the right to
         purchase up to 2.5% of the common stock of COI outstanding at the
         Closing. The COI Warrants are exercisable only at the times, and in the
         proportions, that Crescent or COI exercises the Warrants. The exercise
         price for the COI Warrants will reflects the same premium as used to
         calculate the purchase price of the Warrants, based upon a valuation of
         COI to be conducted by a mutually agreed upon independent appraiser
         once a trading market for COI common stock has been established.
 
       - At the Closing, Magellan will either (i) provide CBHS with bridge
         financing, secured by CBHS' receivables, for a one-year term in the
         maximum amount of $55 million to fund CBHS' anticipated working capital
         needs during its first year of operation or (ii) provide a guarantee
         under certain circumstances, not to exceed $65 million, for a CBHS bank
         line of credit secured by CBHS' receivables. CBHS has received a loan
         commitment from a group of commercial banks to provide a line of credit
         of up to $100 million pursuant to a 5-year revolving credit facility.
 
       - Both the Company and COI will contribute an additional $2.5 million in
         cash to the capital of CBHS within five days after Closing. In
         addition, each of the Company and COI will make a commitment to loan
         CBHS up to $17.5 million each, for a period of five years. The Company
         will have the right to require CBHS to draw down a portion of its loan
         commitment, which will be funded equally by the Company and COI, and
         will be used in the manner directed by the Company.
 
        5. Such other matters as may properly come before the Annual Meeting.
 
    The Board is not aware of any other matters that may properly come before
the Annual Meeting. If any such other matters properly come before the Annual
Meeting, it is the intention of the Proxies to vote in accordance with their
best judgment on such matters.
 
    THE BOARD HAS UNANIMOUSLY APPROVED THE NOMINEES FOR ELECTION AS DIRECTORS,
THE CERTIFICATE AMENDMENT AND THE 1997 PLAN, AND RECOMMENDS THAT STOCKHOLDERS
VOTE FOR THE PROPOSAL TO ELECT SUCH NOMINEES, FOR THE CERTIFICATE AMENDMENT AND
FOR THE 1997 PLAN. IN ADDITION, THE BOARD HAS UNANIMOUSLY APPROVED (WITH
DIRECTOR DARLA D. MOORE NOT PARTICIPATING BECAUSE OF HER BENEFICIAL OWNERSHIP IN
CRESCENT) THE CRESCENT TRANSACTIONS AND RECOMMENDS THAT STOCKHOLDERS VOTE FOR
THE CRESCENT TRANSACTIONS.
 
                                       15
<PAGE>
                                     VOTING
 
    The Board has fixed the close of business on April 11, 1997, as the record
date for determining the stockholders entitled to notice of, and to vote at, the
Annual Meeting. On the record date, 28,806,181 shares of Common Stock were
outstanding. Each share is entitled to one vote on each matter presented for a
vote at the Annual Meeting. The presence in person or by proxy of the holders of
a majority of the shares of Common Stock outstanding on the record date
constitutes a quorum for the transaction of business at the Annual Meeting. A
stockholder who has returned a proxy may revoke it at any time before the Annual
Meeting by executing a later-dated proxy, by voting by ballot at the Annual
Meeting or by filing with the inspector of election an instrument of revocation.
 
    Stockholders should specify their choices on the enclosed proxy card. If no
specific instructions are given with respect to the matters to be acted upon,
the shares represented by a properly signed proxy card will be voted FOR the
proposal to elect the nominees as directors, FOR the Certificate Amendment, FOR
the 1997 Plan and FOR the Crescent Transactions. If any other matters properly
come before the Annual Meeting, the Proxies will vote on such matters in their
discretion.
 
    Shares held by stockholders present at the Annual Meeting in person who do
not vote and ballots marked "abstain" or "withheld" will be counted as present
at the Annual Meeting for quorum purposes. With respect to the election of
directors, abstentions and broker non-votes will have no effect on the outcome
of the vote. With respect to the 1997 Plan, abstentions will have the effect of
a vote against the 1997 Plan and broker non-votes will have no effect on the
outcome of the vote. With respect to the Certificate Amendment and the Crescent
Transactions, abstentions and broker non-votes will have the effect of votes
against such proposals. There are no rights of appraisal or similar dissenters'
rights with respect to any matter to be acted upon pursuant to this Proxy
Statement.
 
VOTING BY ESOP PARTICIPANTS
 
    Each participant in the ESOP is being sent a Proxy Statement and an ESOP
proxy card to vote the Common Stock allocated to such participant's ESOP Account
(Allocated Shares). The ESOP proxy card may be used by a participant to give
directions to the ESOP Trustee as to how such participant's Allocated Shares
should be voted. In order to give directions to the ESOP Trustee, a participant
must complete, sign and date the ESOP proxy card and return it to the ESOP
Trustee in a timely manner. To be considered timely, the ESOP Trustee must
receive the ESOP proxy card prior to the Annual Meeting. As of the record date,
204,027 shares of Common Stock were held by the ESOP Trustee and eligible to be
voted at the Annual Meeting.
 
    Under the terms of the ESOP, the ESOP Trustee is required to keep
participant voting instructions confidential and may not divulge such
instructions to any person, including officers and employees of the Company.
Neither the ESOP Trustee nor the Administrative Committee of the ESOP
(consisting of three officers of the Company) will make recommendations to
participants about whether or how to vote.
 
                            SOLICITATION OF PROXIES
 
    The cost of soliciting proxies will be paid by the Company. Banks, brokers
and other custodians, nominees and fiduciaries are requested to forward proxy
materials to the beneficial owners of Common Stock and to secure their voting
instructions, if necessary. The Company will reimburse such persons for their
reasonable out-of-pocket expenses in forwarding proxy materials to the
beneficial owners of Common Stock. Certain officers and other employees of the
Company, who will receive no compensation for their services other than their
regular compensation, may solicit proxies by mail, telephone or personal
contact. In addition, the firm of MacKenzie Partners, Inc. has been retained by
the Company to assist in the solicitation of proxies for a fee of approximately
$7,500 plus expenses.

                             ELECTION OF DIRECTORS
 
    Under the Certificate of Incorporation, the number of directors is currently
fixed at eight. The directors are divided into three classes, with the nominees
in a single class being elected each year to serve three-year terms. At the
Annual Meeting, the Board will nominate three directors to serve as directors
for three-year terms expiring at the 2000 annual meeting of stockholders or
until their successors are duly elected and qualified. Of the current eight
directors, the five Continuing Directors will continue to serve after the Annual
Meeting, three for terms expiring in 1998 and two for terms expiring in 1999.
 
    G. Fred DiBona, Jr. was elected to the Board on January 22, 1996 for a term
expiring in 1998 pursuant to the Green Spring Stockholders Agreement. See
"Certain Relationships and Related Transactions." The terms of the Private
Placement Agreements provide that Rainwater-Magellan has the right to designate
a nominee acceptable to the Company for election as a director of the Company
for so long as the Rainwater Group continues to own beneficially a specified
minimum number of shares of Common Stock. Darla D. Moore was designated by
Rainwater-Magellan for election as director and Ms. Moore was elected a director
by the Board on February 22, 1996. See "Crescent Transactions--Interested
Parties."
 
    If the nominees listed below are unable to serve (which is not anticipated),

vote all valid proxies for the election of such substitute nominees. The Proxies
may not vote proxies for a greater number of nominees than the number named
below.
 
    The table below sets forth the name and certain other information about the
persons nominated for election as directors and the Continuing Directors.

                             COMPENSATION COMMITTEE
                        REPORT ON EXECUTIVE COMPENSATION
 
    The Compensation Committee is responsible for establishing policies with
respect to compensation paid by the Company to its executive officers. The
Compensation Committee approves the design of all compensation plans applicable
to executive officers; negotiates, reviews and/or approves terms of employment
agreements with certain of the Company's executive officers; reviews and
approves performance goals; establishes award opportunities; determines
appropriate base salaries; approves incentive award payouts and oversees the
ongoing operation of the various plans as they relate to executive officers. The
Compensation Committee consists of directors who are not employees of the
Company and who are not eligible to participate in any of the plans that the
Compensation Committee administers. A subcommittee of the Compensation
Committee, which is comprised solely of "outside directors" as such term is
defined by Section 162(m) of the Code, administers the Company's stock option
plans and other compensation arrangements that constitute "qualified
performance-based compensation," as defined by Section 162(m) of the Code.
 
    POLICIES.  In 1993 the Compensation Committee retained an independent
compensation consultant to advise it with respect to executive and other officer
total compensation, including base salaries, annual incentive plans, benefits
and stock-based and long-term incentive compensation. The compensation
consultant interviewed each independent director of the Company and reported to
the Compensation Committee that the independent directors believed (i) total
compensation of the Company's executive officers should be between the 60th and
70th percentiles of a peer group based on performance to attract and retain
qualified executives and (ii) a significant portion of executive officer
compensation should be performance-based. The Company's peer group consists of
specific hospital management and healthcare companies, which the Compensation
Committee believes reflects the talent pool from which the Company might draw
and provides a useful benchmark for the competitiveness of compensation of the
Company's present executive officers.
 
    The compensation consultant reported to the Compensation Committee that
total compensation for the Company's executive officers prior to the 1994 fiscal
year fell between the 40th and 50th percentiles of total compensation for peer
group executive officers. With regard to base salary, the consultant reported
that the base salary of the Company's chief executive officer was below the 50th
percentile of the peer group chief executive officers and that other executive
officer salaries were competitive, falling between the 50th and 66th percentiles
of comparable peer group positions. With regard to annual incentive
compensation, the consultant reported that the percentage of base salary paid by
the Company as a bonus when the annual incentive target is met was slightly
below the peer group median and that the bonuses paid by the Company when the
target is exceeded were above the peer group median.
 
    With regard to benefits, the consultant determined that executive officer
benefits as a percentage of base salary were below the 50th percentile for the
peer group and, in the case of the chief executive officer, were substantially
below the 50th percentile for peer group chief executive officers. With regard
to stock-based compensation, the consultant determined that, for years after
1992, stock options available for grant were below the 50th percentile of the
peer group for executive officers generally and substantially below the 50th
percentile of the peer group for the chief executive officer.
 
    Based in substantial part on the findings and recommendations of the
independent compensation consultant and the results of the compensation
consultant's interviews of the Company's independent directors, the Compensation
Committee adopted the following policies with respect to executive officer
compensation.
 
        1.  BASE SALARY--Executive officer base salaries should be at
    approximately the 50th percentile of the peer group developed by the
    compensation consultant, subject to increase to a higher percentile for
    individual executive officers based on performance.
 
                                       24
<PAGE>
        2.  PERFORMANCE-BASED COMPENSATION--A significant portion of executive
    officer compensation should be performance-based.
 
    In implementing these policies, the Compensation Committee has, since the
1993 compensation consultant report, received additional advice from outside
consultants with respect to stock option plans and other incentive compensation
and recommended that the Company adopt certain performance-based compensation
plans. These plans were adopted by the Company after receiving necessary
approvals from the Board and stockholders. The plans that are currently in force
are described below.
 
    1996 STOCK OPTION PLAN.  Under the 1996 Stock Option Plan, key employees of
the Company (including executive officers) may be granted options to purchase
Common Stock. The Board has reserved 1,750,000 shares of Common Stock under the
1996 Stock Option Plans.
 
    ANNUAL INCENTIVE PLAN.  Under the Annual Incentive Plan, annual bonuses for
executive officers are payable as a percentage of base salary based on an income
target that is established by the Compensation Committee after review of the
Company's budget for the fiscal year. The Compensation Committee believes that
income before income taxes was an appropriate measure of the Company's 1996
performance. If the target is met, executive officers other than the Chairman
earn a bonus of 40% of base salary. The Chairman earns a bonus of 50% of base
salary if the target is met. If the target is exceeded, bonuses are increased to
a maximum of 85% of base salary when income before income taxes equals or
exceeds 120% of the target.
 
    EXECUTIVE BENEFITS PLAN.  The Company adopted the EBP in 1993 on the
recommendation of the compensation consultant. The EBP is funded through a
performance-based component and a fixed component and has been structured to
provide an incentive for executive officers to remain with the Company.
 
    Under the performance-based component, an amount equal to one-third of an
executive officer's annual bonus, if any, is paid by the Company to a trust and
invested in one or more mutual funds. The amount contributed to the trust and
any appreciation or contributions is paid to the executive officer on a date
selected by the executive officer prior to funding (but not earlier than two
years after funding or later than normal retirement date). Payments from the
trust to the executive officer are forfeited if, at the time payment would
otherwise be made, the executive officer is no longer employed by the Company
and is in violation of a non-competition agreement signed prior to funding.
 
    The fixed component of the EBP is an annual amount equal to 19.5% of the
base salary of the chief executive officer and 11% of the base salary of other
executive officers. At the election of each executive officer, the fixed
component may be used to make additional payments to the trust described above
or to purchase life, spousal life or disability insurance. Amounts deposited in
the trust are subject to forfeiture, as described above.
 
    DISCRETIONARY INCENTIVE PLAN.  On December 17, 1996, the Compensation
Committee approved a discretionary incentive plan for fiscal 1996, pursuant to
which $500,000 was distributed to the Named Executive Officers, other officers
and key employees of the Company. The Compensation Committee approved Mr.
Crawford's discretionary incentive payment of $153,500, and Mr. Crawford
approved the allocation of the remaining $346,500 of the discretionary incentive
pool. The Compensation Committee awarded the payments due in part to the
numerous positive events and transactions that occurred in fiscal 1996,
including, but not limited to, the Green Spring Acquisition, the issuance of the
Shares, the Share Repurchase and integration efforts between the provider,
managed care and public sector business segments.
 
    CHIEF EXECUTIVE OFFICER COMPENSATION.  In fiscal 1996, the compensation of
E. Mac Crawford, the Company's Chief Executive Officer, included base
compensation of $712,500 and benefits under the EBP of $163,636. Mr. Crawford's
base salary was increased to $750,000 effective January 1, 1996.
 
                                       25
<PAGE>
Mr. Crawford's benefits under the EBP include $142,191 deposited in the trust
described above, which amount is subject to forfeiture under certain
circumstances, and $10,331 of whole life insurance premiums. The Compensation
Committee believes that Mr. Crawford's 1996 base salary approximated the median
chief executive officer base salary of the peer group. The Compensation
Committee also considered Mr. Crawford's implementation in 1995 of the Company's
strategic plan through the creation of Magellan Health Services through the
acquisition of managed care expertise through the Green Spring Acquisition and
public sector capability through the acquisition of National Mentor, Inc. and
the creation of Magellan Public Solutions.
 
    Under the Annual Incentive Plan targets established by the Compensation
Committee in the first quarter of fiscal 1996, income before income taxes for
fiscal 1996 was below the targeted income levels. Accordingly, Mr. Crawford did
not receive a bonus for fiscal 1996 pursuant to the provisions of the Annual
Incentive Plan. None of the EBP benefits accrued were performance-based.
 
    The Compensation Committee approved a discretionary incentive payment of
$153,500 to Mr. Crawford under the Discretionary Incentive Plan. This payment
was awarded to Mr. Crawford due to the Green Spring Acquisition, the issuance of
the Shares, the Share Repurchase and integration efforts between the provider,
managed care and public sector business segments.
 
    NON-DEDUCTIBILITY OF CERTAIN COMPENSATION.  The Company is party to an
employment agreement with Mr. Crawford. Under the terms of the agreement, the
compensation paid to Mr. Crawford may exceed $1 million in certain years.
Section 162(m) of the Code generally provides that, subject to certain
exceptions, a publicly-held corporation such as the Company, may not deduct for
federal income tax purposes compensation paid to any of its Named Executive
Officers in excess of $1 million annually. The Compensation Committee determined
that the benefit to the Company of entering into an extended employment contract
with Mr. Crawford offset the loss of a potential tax deduction in future years.
 
                             Andre C. Dimitriadis (Chairman)
                             Edwin M. Banks(1)
                             A.D. Frazier
                             Gerald L. McManis
 
- ------------------------
 
(1) Appointed effective January 1997.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    Mr. McManis, a member of the Compensation Committee, is the President of
MAI, a healthcare development and management consulting firm. During fiscal
1996, MAI provided consulting services to the Company related to the development
of strategic plans and a review of the Company's business processes. Management
believes that the services received from MAI were negotiated on terms as
favorable as could be obtained from an unaffiliated third party. The Company
incurred approximately $274,000 in fees for such services during fiscal 1996 and
reimbursed MAI approximately $13,000 for expenses. Mr. McManis is not a member
of the subcommittee that administers the Company's stock option plans and other
"qualified performance-based compensation."
 
EMPLOYMENT AGREEMENTS AND CHANGE OF CONTROL PROVISIONS
 
    CHANGE OF CONTROL PROVISIONS GENERALLY.  Each Named Executive Officer,
except Mr. Crawford, has an Employment Agreement with a change of control
provision that may be triggered by the Closing. Each such Named Executive
Officer has waived the change of control provision to the extent (if any) it
would be triggered by the Closing.
 
    E. MAC CRAWFORD.  The Company has an Employment Agreement with Mr. Crawford
for a three-year term beginning March 1, 1997. The agreement provides for a base
salary of $825,000 and bonus
 
                                       26
<PAGE>
compensation payable on January 2, 1998 (the "Contract Bonus"), determined as
follows: $10 million LESS (i) if none of the 462,990 options (the number of
stock options held by Mr. Crawford on October 1, 1995 under the 1992 Stock
Option Plan) have been exercised as of January 2, 1998, the result obtained by
multiplying 462,990 by the lesser of (a) $18 LESS $4.36 (the exercise price of
the stock options held by Mr. Crawford on October 1, 1995 under the 1992 Stock
Option Plan) and (b) the arithmetic average of the closing sale price per share
of the Common Stock for the ten trading days immediately preceding the date of
payment LESS $4.36, or (ii) the sum of the result obtained by multiplying the
number of stock options held by Mr. Crawford on October 1, 1995 under the 1992
Stock Option Plan that have not been exercised as of January 2, 1998 by the
lesser of (a) or (b) and the result obtained by multiplying the number of stock
options held by Mr. Crawford on October 1, 1995 under the 1992 Stock Option Plan
that were exercised prior to January 2, 1998 by $13.64. The agreement also
provides that Mr. Crawford will receive a bonus of $2.475 million if the
Crescent Transactions are closed. In addition, Mr. Crawford will receive other
bonuses and benefits that are provided to the Company's other executive
officers. The agreement also provides for severance payments to Mr. Crawford
upon termination by the Company (including certain constructive termination
events, such as a substantial change in Mr. Crawford's duties, but not including
termination for cause), termination due to death or disability, or upon Mr.
Crawford's resignation, or after a change of control (as defined in the
agreement, which definition specifically excludes the Crescent Transactions) or
if stockholders do not approve the 1997 Plan before September 1, 1997. Such
severance payments would consist of (i) the Contract Bonus, (ii) five years
salary at the then current salary level, and (iii) portion(s) of any bonus or
other incentive compensation accrued through the date of termination. In
addition, if Mr. Crawford resigns or is terminated following a change of control
or the failure of stockholders to approve the 1997 Plan, Mr. Crawford will be
paid a "gross-up" payment intended to compensate Mr. Crawford if certain excise
taxes would be imposed under the Code in such cases. If Mr. Crawford were to
resign (excluding a resignation that constitutes a constructive termination), he
also would be paid an amount determined by multiplying the number of unexercised
options then held by Mr. Crawford by the excess, if any, of $18 over the
arithmetic average of the closing sale price of the Common Stock for the ten
trading days immediately preceding the resignation. Subject to certain
exceptions, the Company will be unable to deduct the compensation and severance
payments to Mr. Crawford to the extent such compensation is in excess of $1
million annually.
 
    CRAIG L. MCKNIGHT.  The Company has an Employment Agreement with Mr.
McKnight for a five-term beginning March 1, 1995. The agreement provides for a
base salary of $350,000 and for bonuses and life and disability insurance
benefits that are competitive with similar benefits for comparable positions
within the investor-owned hospital industry. The agreement also provides for
severance payments upon termination without cause, termination due to death or
disability, or resignation after a change of control (as defined in the
agreement). Upon any such termination, Mr. McKnight would receive the greater of
(i) all salary payments that would come due during the term of the agreement
subsequent to termination and (ii) two years' salary at the then current salary
level and a portion of any bonus or other cash incentive compensation accrued
through the date of termination.
 
    STEVE J. DAVIS.  The Company has an Employment Agreement with Mr. Davis for
a three-year term beginning May 7, 1996. The agreement provides for a base
salary of $300,000 and for bonuses and life and disability insurance benefits
that are competitive with similar benefits for comparable positions within the
investor-owned hospital industry. The agreement also provides for severance
payments upon termination without cause, termination due to death or disability,
or resignation after a change of control (as defined in the agreement). Upon any
such termination, Mr. Davis would receive the greater of (i) all salary payments
that would become due during the term of the agreement subsequent to termination
or (ii) one year's salary at the then current salary level and a portion of any
bonus or other cash incentive compensation accrued through the date of
termination.
 
    HENRY T. HARBIN.  Green Spring has an Employment Agreement with Dr. Harbin
for a three-year term beginning February 28, 1996. The agreement provides that
the Company will pay Dr. Harbin a base
 
                                       27
<PAGE>
salary, which will be fixed from time to time by the Board of Directors of Green
Spring, and for fringe benefits comparable to those offered to all Green Spring
employees. The Company has a Compensation Agreement with Dr. Harbin for a
four-year term beginning December 13, 1995. The Compensation Agreement provides
that the Company will pay Dr. Harbin a bonus, one-half of which will be paid on
December 13, 1998 and the remaining one-half on December 13, 1999. The bonus
will be: $2.25 million LESS the aggregate value of all cash and non-cash
compensation paid or payable to Dr. Harbin by the Company during the term of the
Compensation Agreement (the "Excluded Amount") other than Dr. Harbin's base
salary as of December 31, 1995 and amounts paid to Dr. Harbin prior to December
13, 1995. The Compensation Agreement also provides that Dr. Harbin is entitled
to receive such bonus if he is terminated without cause, terminated due to death
or disability, or terminated or resigns after a change of control (as defined in
the agreement). The Excluded Amount also includes the in-the-money portion of
any stock options that Dr. Harbin now holds or may hold in the future. The value
of the in-the-money portion of the stock options is calculated as follows: (i)
for unexercised options, the value is the number of unexercised options
multiplied by the average of the closing prices of the Common Stock on the New
York Stock Exchange for the ten trading days preceding the payment date LESS the
aggregate exercise price payable in connection with the exercise of such
options, and (ii) to with respect to exercised options, the value is the greater
of (A) of the closing prices of the Common Stock on the date of exercise
multiplied by the number of options exercised in connection with such exercise
LESS the aggregate exercise price payable in connection with such exercises and
(B) the value that would have been ascribed to such options if the options had
been valued in accordance with the provisions for unexercised options described
above. The Excluded Amount does not include any value related to unvested stock
options to the extent that such options will not vest in the ordinary course
before the end of the term of the Compensation Agreement.
 
    JOHN M. DESTEFANIS.  The Company has an Employment Agreement with Mr.
DeStefanis for a four-year term beginning April 15, 1996. The agreement provides
for a base salary of $350,000 per year and for bonuses and life and disability
insurance benefits that are competitive with similar benefits for comparable
positions within the investor-owned hospital industry. The agreement also
provides for severance payments upon termination without cause, termination due
to death or disability and termination after a change of control (as defined in
the agreement). Upon any such termination Mr. DeStefanis would receive a greater
of (i) all salary payments that would come due during the term of the agreement
subsequent to termination or (ii) one years' salary at the then current salary
level and a portion of any bonus or other cash incentive compensation accrued
through the date of termination.
 
    At the Closing, CBHS will assume the Company's Employment Agreement with Mr.
DeStefanis. The options that have been awarded to Mr. DeStefanis under the
Company's stock option plans will continue in force and will continue to be
exercisable for Common Stock according to their terms.
 
    EXECUTIVE BENEFIT PLAN.  The terms of the EBP provide that amounts deposited
in the trust on behalf of executive officers are to be paid to executive
officers, together with any appreciation in such amounts, upon a change of
control of the Company if the change of control occurs prior to the scheduled
date for distribution of amounts held in the trust. The trust agreement defines
a "change of control" as the replacement of 50% or more of the members of the
Board within a 12-month period that is followed by the termination of employment
within a 12-month period of one-third or more of the employees who participate
in the EBP. The Closing will not constitute a change of control for purposes of
the EBP.

    The Company acquired a 51%-equity interest in Green Spring on December 13,
1995 for approximately $68.9 million in cash, the issuance of Common Stock
valued at approximately $4.3 million and the contribution of GPA, a wholly-owned
subsidiary of the Company, to Green Spring. On December 20, 1995, the Company

BACKGROUND
 
    In recent years, the Company has adopted a strategy to develop and operate a
fully integrated behavioral healthcare company in order to capture a higher
portion of the healthcare premium dollar. The Company has pursued this strategy
through hospital acquisitions and joint ventures, the acquisition of National
Mentor, Inc., and the acquisition of a 61%-interest in Green Spring.
 
    The Company has experienced some success in implementing these strategies.
However, competition from a variety of healthcare companies, changes in the
reimbursement rates and changes in the hospital business payor mix, including an
increase in the number of managed care providers, have led management to look
for ways to accelerate these strategies through transactions such as the
Crescent Transactions.
 
PRE-TRANSACTION CONTACTS
 
    The Company has engaged in ongoing discussions with the Rainwater Group with
respect to a possible sale of Company real estate and/or a possible equity
investment by the Rainwater Group in the Company for more than three years. In
1993, Mr. Rainwater first approached the Company with respect to a proposal
pursuant to which the Company would sell substantially all of its psychiatric
hospital properties to a new REIT being sponsored by Mr. Rainwater. This contact
involved preliminary discussions only and did not result in agreement upon
definitive terms of a transaction. The Company also had preliminary discussions
with other REITs regarding their interest in such a transaction, but such
discussions did not result in a formal proposal. Subsequently, Mr. Rainwater
kept in contact with Company management and at various times repeated his
interest in making an equity investment in the Company.
 
    In October, 1995 Mr. Rainwater contacted Mr. Crawford and expressed his
interest in making an investment in the Company.
 
    At its November, 1995 meeting, the Board reviewed a proposal from Mr.
Rainwater with respect to an equity investment in the Company, which Company
management had previously discussed with Mr. Rainwater and his representatives.
The Board retained Dean Witter to assist it in evaluating the proposal and, if
appropriate, to render a fairness opinion. This proposal was considered further
by the Board at its last December, 1995 meeting. These discussions eventually
resulted in the Private Placement, which was approved by the Board on December
22, 1995 and closed on January 25, 1996. The Private Placement resulted in
Rainwater-Magellan paying an aggregate of $69.732 million to acquire 4,000,000
shares of Common Stock and the Rainwater-Magellan Warrant, which can be
exercised for an additional 2,000,000 shares of Common Stock at an exercise
price of $26.15 per share. In the aggregate, the Common Stock issued in the
Private Placement and the Common Stock underlying the Rainwater-Magellan Warrant
represent 19.6% of the outstanding Common Stock as of December 31, 1996. Dean
Witter issued a fairness opinion to the Company, but did not participate in any
negotiations, in connection with the Private Placement.
 
    On January 25, 1996, the Rainwater Group purchased the Shares and the
Rainwater-Magellan Warrant in the Private Placement. On February 22, 1996, the
Board elected Mr. Rainwater's spouse, Darla D. Moore, a director of the Company
to serve until the 1999 annual meeting of stockholders pursuant to a provision
in the Private Placement Agreements. At the same meeting, the Board created a
Finance Committee and appointed Ms. Moore as chairperson.
 
    During early 1996, management considered various possible transactions
involving a sale and leaseback of the Company's hospital real estate to a REIT.
 
    On June 17, 1996, the Board held a meeting at which Dean Witter presented
strategic alternatives available to the Company. At this meeting, the Board
discussed sale of the Company's provider assets, expansion of existing joint
venture relationships, implementation of an aggressive acquisition strategy,
including various acquisition opportunities available to the Company and
refinancing of the Notes. No changes in the Company's strategic direction
resulted from the alternatives discussed at this meeting.
 
    During the summer of 1996, management considered various franchising
opportunities in which the Company would license the right to use the "CHARTER"
name, protocols and other intellectual property
 
                                       32
<PAGE>
to third parties. The Company held preliminary discussions with a franchise
operating company regarding joint venture opportunities, but no proposal or
economic terms resulted from these discussions. In early August 1996, Mr.
Rainwater contacted Mr. Crawford to discuss a possible real estate transaction.
On August 29, 1996, Mr. Crawford met with Mr. Rainwater to discuss Mr.
Rainwater's proposed transaction, at which time the concept of a possible real
estate and franchise transaction was first discussed.
 
    The Board met in early September 1996 to discuss the proposed real estate
and franchise transaction. The Board retained Dean Witter to assist it in
evaluating the proposed transaction. Dean Witter did not negotiate or
participate in the negotiation of the Crescent Transaction Documents. Based on
its own experience and knowledge of REIT financings of behavioral healthcare
companies and the advice of its outside advisors, the Board did not contact any
other parties regarding a possible real estate and franchise transaction. The
Finance Committee did not independently consider the proposed transaction or
make any recommendation to proceed with the proposed transaction. Ms. Moore was
not present at any meetings at which the Board considered the proposed
transaction, and did not participate in any negotiations with respect to the
proposed transaction.
 
    On September 20, Mr. Crawford met in New York with Mr. Rainwater to discuss
the basic structure of the transaction, including the sale of real property,
franchise arrangement and CBHS joint venture. On October 2, 1996, Messrs.
Crawford and McKnight and certain other members of management met in Fort Worth,
Texas with Messrs. Rainwater, Haddock and Goff to further discuss the proposed
transaction including general terms regarding purchase price, base rent,
escalator rent, warrant exercise price, vesting and underlying shares, franchise
fees and CBHS equity split. Management and Crescent representatives had further
discussions over the next several weeks to clarify the general terms of the
proposed transaction.
 
    On November 1, Mr. Crawford met with Mr. Goff to discuss outstanding issues
regarding the general terms of the proposed transaction. On November 20, the
Company and Crescent agreed to preliminary terms for the transaction and agreed
to negotiate a Master Agreement, which would serve as the basis for the
definitive Crescent Transaction Documents. On November 25, Mr. Crawford met with
Mr. Goff to discuss the terms of the Master Agreement and the anticipated
operation of CBHS as a joint venture.
 
    On December 6, Messrs. Haddock and Goff met in Atlanta with Messrs.
Crawford, McKnight and Davis and other members of management to discuss a
timeline for the proposed transaction and the detail with which the terms of the
proposed transaction would be reflected in the Master Agreement. Management and
Crescent representatives had further discussions over the next several days to
discuss the structure and content of the Master Agreement. On December 17, the
Board met with management and the Company's legal and financial advisors to
review the then current terms of the proposed Master Agreement.
 
    On December 18, Messrs. Crawford, McKnight and Davis, other members of
management and the Company's legal counsel met in Fort Worth with Messrs.
Haddock and Goff and other Crescent representatives to discuss the remaining
open terms of the Master Agreement. Discussions focused on lease/franchise
renewal terms, joint venture governance and operation, funding of CBHS,
franchise fee subordination and warrant structure, vesting and exercise price.
The parties resolved the remaining open issues with respect to the Master
Agreement on December 24 and signed the Master Agreement on December 26.
 
    During late December and early January, the parties negotiated the language
of the definitive Crescent Transaction Documents reflecting the business terms
set forth in the Master Agreement. On January 14, the Board met with management,
Dean Witter and its other advisors to review the status of the negotiations and
to discuss certain open issues with respect to the Crescent Transaction
Documents. Discussions focused on the nature of representations and warranties,
pre-closing covenants, events of default, indemnification and similar legal
concepts.
 
                                       33
<PAGE>
    On January 29, the Board met with management, Dean Witter and its other
advisors to review final drafts of the Crescent Transaction Documents. At the
meeting, Dean Witter delivered its opinion to the Board to the effect that the
consideration to be received in the Crescent Transactions was fair, from a
financial point of view, to the Company and the Board approved the Crescent
Transaction Documents. On January 30, the Crescent Transactions were publicly
announced.
 
DECISION TO ENGAGE IN THE CRESCENT TRANSACTIONS
 
    The Board considered the following factors in its evaluation of the Crescent
Transactions. While the Board considered each of these factors, its decision to
engage in the Crescent Transactions was made on these considerations taken in
the aggregate. No single factor was dispositive to the Board's decision to
engage in the Crescent Transactions.
 
    - The receipt by the Company of $400 million in cash (before costs estimated
      at $12.5 million) and the COI Warrants. The Company anticipates that the
      cash it receives will allow it to pursue acquisitions in the managed care,
      public sector and related information services segments, develop new
      products, increase managed care and public sector marketing efforts, and
      reduce debt.
 
    - The ability of CBHS to pay the Franchise Fees. Based on the historical
      operating results of Charter, the Board believes that Magellan's results
      of operations, will not be adversely impacted.
 
    - The right of the Noteholders, after the Closing, to have the Company
      repurchase their Notes at a purchase price equal to 101% of the aggregate
      principal amount of the Notes, plus accrued and unpaid interest. Such a
      repurchase could impede or delay the Company's acquisition and product
      development strategies. The Board believes that it is unlikely that the
      Company will be required to repurchase all of the Notes because the recent
      bid and asked prices of the Notes on the New York Stock Exchange have been
      higher than the price at which the Company would be required to repurchase
      the Notes. Moreover, in the event that the Company is required to
      repurchase some or all of the Notes, the Board believes the Company could
      use the net proceeds from the Crescent Transactions and additional
      borrowings under its new credit agreement to finance the repurchase of the
      Notes and significantly reduce the Company's interest expense and improve
      its capital structure.
 
    - The removal of substantially all of the net assets and results of
      operations of the Facilities from the Company's financial statements. The
      Company believes that this will enhance its stock market valuation, which
      may enhance the Company's ability to pursue acquisitions.
 
    - The ability of CBHS to accelerate its acquisition strategy and lead the
      consolidation of the provider segment of the behavioral healthcare
      industry. CBHS seeks to increase provider capability, both on an inpatient
      and outpatient basis, through an aggressive program of acquisitions and
      joint ventures. Through the Crescent Transactions, CBHS will have access
      to Crescent's financing and real estate expertise to enhance CBHS' ability
      to capitalize on opportunities for growth. Such acquisitions and joint
      ventures could, individually or in the aggregate, be material to CBHS (and
      indirectly to Magellan). As an owner of CBHS, Magellan has the right to
      participate in the approval of any significant acquisition or joint
      venture by CBHS.
 
    - The fairness opinion of Dean Witter, to the effect that the consideration
      to be received in the Crescent Transactions is fair, from a financial
      point of view, to the Company.
    - The rent payments under the Facilities Lease represent a higher cost of
      capital than certain traditional financing alternatives. However, the
      Board views the Crescent Transactions primarily as a strategic realignment
      of the Company and believes that the consideration received from the
      Crescent Transactions, the removal of the net assets and results of
      operations of the Facilities from the Company's financial statements, and
      the Company's retention of the "CHARTER" name and other intangible rights
      relating to its hospital provider business substantially outweigh the cost
      of capital implied by the rent payments under the Facilities Lease.
 
                                       34
<PAGE>
    - The Company's loss of operating control over the Facilities. After the
      Closing, the Facilities will be operated by CBHS and the Company will not
      be able to control CBHS. However, the Company will have the right to
      designate one-half of the members of the CBHS Board. Therefore, the Board
      does not view the loss of control as a significant disadvantage because of
      the continuity of the management team, with whom it is familiar and the
      Company's representation on the CBHS Board.
 
    - The Company's retention of the "CHARTER" name and other valuable
      intangible rights relating to its hospital provider business, which will
      allow the Company to continue receiving revenues from these assets. During
      the term of the Master Franchise Agreement, the Company will have the
      right to receive Franchise Fees, which initially will be $81 million
      annually. After the Closing, the Company will be able to pursue
      opportunities to franchise the "CHARTER" name, services and protocols to
      companies other than CBHS.
 
THE TRANSACTIONS
 
    The Crescent Transactions will be accomplished in component parts
representing one integrated transaction. The Company has entered into the
Crescent Purchase Agreement, pursuant to which the Company will sell the
Purchased Facilities to Crescent. The Purchased Facilities include 83 behavioral
healthcare facilities and related medical office buildings. The Purchased
Facilities do not include any facilities that are leased, operated by joint
ventures, closed prior to December 26, 1996 or located outside the United
States. See "Crescent Transactions--Crescent Purchase Agreement."
 
    The Company will enter into the CBHS Contribution Agreement, pursuant to
which the Company will sell and contribute to CBHS certain property and
intangible rights used in connection with the Facilities in exchange for the
CBHS Interest. The property that will be contributed to CBHS includes interests
in five acute care psychiatric hospitals and other ancillary facilities that the
Company currently leases from third parties. The property that will be sold to
CBHS includes without limitation, all supplies and inventory, certain equipment,
contract rights and business records (other than financial statements), as well
as certain liabilities. In addition, COI will make an initial cash contribution
of $5 million to CBHS. See "Crescent Transactions--CBHS Contribution Agreement."
 
    At the Closing, the Company will either (i) provide CBHS with bridge
financing, secured by CBHS' receivables, for a one-year term in the maximum
amount of $55 million to fund CBHS' reasonable working capital needs during its
first year of operation or (ii) provide a guarantee, under certain
circumstances, not to exceed $65 million, for a CBHS bank line of credit secured
by CBHS' receivables. CBHS has received a loan commitment from a group of
commercial banks to provide a line of credit of up to $100 million pursuant to a
5-year revolving credit facility. See "Crescent Transactions--Loan and Security
Agreement" and "--CBHS Contribution Agreement".
 
    The Company will retain ownership of its intellectual property, including
trademarks. The Company holds common law trademark rights to the "CHARTER"
trademark. It also holds rights to "CHARTER COUNSELING CENTER" and "CHARTER
HEALTH CENTER" which are trademarks registered in the United States Patent and
Trademark Office. The Company also owns rights to other "CHARTER" related marks,
trademark applications for which are now pending in the United States Patent and
Trademark Office. The Company will retain ownership of these trademarks, the
"CHARTER" protocols and certain other intellectual property assets, and will
also continue to own and operate the "1-800-CHARTER" telephone call center.
 
    CBHS will enter into the Facilities Lease, pursuant to which Crescent will
lease the Purchased Facilities to CBHS. CBHS will pay annual base rent to
Crescent, which will initially be $40 million, increasing at 5% compounded
annually. See "Crescent Transactions--Facilities Lease."
 
    The Company will enter into the Master Franchise Agreement with CBHS and a
Subsidiary Franchise Agreement with each CBHS entity that operates a Facility.
Pursuant to the franchise agreements, the
 
                                       35
<PAGE>
Company will provide certain services to CBHS that are necessary for CBHS to
operate the Facilities. The franchise agreements give CBHS the right to use the
"CHARTER" name, trademarks owned by the Company, the "CHARTER" protocols and
certain other intellectual property retained by the Company. CBHS will pay
Franchise Fees to the Company in exchange for the rights granted under the
franchise agreements, which initially will be $81 million, with escalation
clauses for inflation and certain contingent amounts based on future revenue
levels. The Franchise Fees are subordinated in payment to the rent due Crescent.
See "Crescent Transactions--Risk Factors, Subordination of Franchise Fees,"
"--Master Franchise Agreement," "--Subsidiary Franchise Agreement" and
"--Subordination Agreement."
 
    Magellan will issue the Warrants to Crescent and COI. See "Crescent
Transactions--Warrant Purchase Agreement."
 
    COI will issue the COI Warrants to Magellan. See "Crescent Transactions--COI
Warrant Purchase Agreement."
 
THE WARRANTS
 
    As part of the Crescent Transactions, Magellan will issue the Warrants
(which will be issued in a series of 11 warrants to each of Crescent and COI).
The aggregate purchase price for the Warrants is included in the consideration
to be paid by Crescent under the Crescent Purchase Agreement. Magellan has
valued the Warrants at $25 million. The issuance of the Warrants is an integral
part of the Crescent Transactions and is intended to align the economic
interests of Crescent and COI with those of Magellan. The issuance of the
Warrants will have no immediate impact on the rights of existing Magellan
stockholders. Any exercise of the Warrants will dilute the voting rights of
existing Magellan stockholders.
    The Warrants are exercisable at various times over the 12 year period after
the Closing and give Crescent and COI each the right to purchase up to 1,283,311
shares of Common Stock at an exercise price of $30 per share. The Warrants will
be exercisable at the following times and in the following amounts:

</TABLE>
 
    Crescent agrees that it will not sell or transfer any of the Warrants to any
other person, except as otherwise permitted under the Warrant Purchase
Agreement. Notwithstanding the foregoing, Crescent may sell or transfer any of
the Warrants and/or Warrant Shares to any person pursuant to, as a result of, or
in connection with (i) a tender offer or an exchange offer approved by the
Board; (ii) the consummation of a merger (provided the Company is not the
surviving corporation in such merger), consolidation, or sale of all or
substantially all of the assets of the Company or (iii) any other "fundamental
change transaction" as defined in the Warrants. Crescent may also transfer the
Warrants to COI if necessary to avoid jeopardizing CEI's qualification as a real
estate investment trust for federal income tax purposes; provided, however, that
in the event of any transfer for such purpose, Crescent provides the Company
with a written opinion of counsel to such effect. No transfer may be made unless
the purported transferee executes an instrument
 
                                       36
<PAGE>
acknowledging that it is bound by the foregoing transfer restriction, and such
instrument is delivered to the Company.
 
    The warrant exercise price may be adjusted to prevent dilution to holders of
the Warrants in the event of a subdivision or combination of the Common Stock, a
dividend payable in shares of Common Stock, or a dividend payable in property
(including cash) other than shares of Common Stock.
 
    For a discussion of other material terms of the Warrants, see "Crescent
Transactions--Warrant Purchase Agreement."
 
RISK FACTORS
 
    Certain factors that stockholders should consider when deciding how to vote
on the Crescent Transactions are discussed below. These factors, individually or
in the aggregate, could have a material adverse effect on the Company.
 
    LOSS OF CONTROL OF THE FACILITIES AND CBHS.  After the Closing, the
Facilities will be operated by CBHS and the Company will not be able to control
CBHS. Magellan's operational input in CBHS will be limited to those rights
provided by the franchise agreements and the CBHS Operating Agreement. For a
more detailed discussion of how CBHS will operate the Facilities under
franchise, see "Crescent Transactions-- Subsidiary Franchise Agreement." See
also "Crescent Transactions--Master Franchise Agreement" and "--CBHS Operating
Agreement."
 
    SUBORDINATION OF PAYMENT OF FRANCHISE FEES.  As part of the Crescent
Transactions, CBHS will lease the Purchased Facilities from Crescent under the
Facilities Lease. See "Crescent Transactions--Facilities Lease." The annual base
rent under the Facilities Lease begins at $40 million and increases at 5% per
year, compounded annually. The Subordination Agreement provides that the
Franchise Fees are subordinated in payment to the $40 million annual base rent,
5% minimum escalator rent and, in certain circumstances, the additional rent due
Crescent under the Facilities Lease. (See "Crescent Transactions--Subordination
Agreement"). If CBHS encounters a decline in earnings or financial difficulties,
such amounts due Crescent will be paid before any Franchise Fees are paid. The
remainder of CBHS' available cash will then be applied in such order of priority
as CBHS may determine, in the reasonable discretion of the CBHS board, to all
other operating expenses of CBHS, including the current and accumulated
Franchise Fees. The Company will be entitled to pursue all available remedies
for breach of the Master Franchise Agreement, except that the Company does not
have the right to take any action that could reasonably be expected to force
CBHS into bankruptcy or receivership.
 
    VOLATILITY OF EARNINGS.  The Company will use the proceeds of the Crescent
Transactions to reduce net interest expense by repaying long-term debt where
possible and investing the remaining proceeds in short-term cash equivalents.
Although the Company's net interest expense will be lower, the Company's reduced
earnings from Charter from the Crescent Transactions could be even more
pronounced. Until Noteholders decide whether or not to sell their Notes (see
"--Risk Factors, Indenture"), the Company will not have flexibility to allocate
its capital resources. Once the Noteholders decide whether or not to sell their
Notes to the Company, capital resource decisions (e.g., acquisitions) may take
time to implement.
 
    The Company derived approximately $809 million, or 60%, of its fiscal 1996
revenue from the Facilities. The Crescent Transactions could reduce the
Company's earnings in the short-term until the net proceeds from the Crescent
Transactions are deployed by the Company. There can be no assurance that the
Company's use of the net proceeds from the Crescent Transactions will increase
the Company's long-term earnings. Although CBHS intends to aggressively grow its
business through acquisitions and joint ventures, there can be no assurance that
such acquisitions and joint ventures will not result in an adverse effect on
CBHS' balance sheet, earnings, cash flow or competitive position, or that any
acquisitions or joint ventures will be consummated. In addition, if CBHS
encounters a decline in earnings or financial
 
                                       37
<PAGE>
difficulties, it is possible that cash flow from CBHS' operations will not be
sufficient to pay the Franchise Fees when due.
 
    LOSS INCURRED AS A RESULT OF THE CRESCENT TRANSACTIONS.  The Company expects
to record a loss before income taxes and extraordinary items related to the
Crescent Transactions. On a pro forma basis at December 31, 1996, the loss
before income taxes and extraordinary items to be incurred as a result of the
Crescent Transactions would have been approximately $57.0 million, which
includes accounts receivable collection fees ($18.0 million), impairment losses
on hospital-based goodwill and other intangible assets ($15.6 million), exit
costs and related commitments ($15.5 million) and loss on sale of property and
equipment ($7.9 million).
 
    NET OPERATING LOSS CARRYFORWARDS.  As of September 30, 1996, the Company
estimated that it had $250 million of NOLs. The Company expects to use a
substantial portion of the NOLs to offset taxable income from fiscal 1997,
including taxable gain from the European Sale. The Company expects to consummate
the European sale in May 1997 for approximately $72.5 million, net of
transaction costs, which will result in a taxable gain to the Company of
approximately $60 million. The Company is currently being (or expects to be)
audited by the IRS for fiscal years 1989 through 1996. All or a portion of the
NOLs may be disallowed by the IRS. Therefore, the NOLs available to offset any
taxable gain recognized on the Crescent Transactions may be substantially
reduced or eliminated. Any remaining NOLs will expire between 2006 and 2010.
 
    NOLs can be used by the Company under certain circumstances to reduce or
eliminate its future federal income tax liability. However, the Code under
certain circumstances eliminates or significantly limits the use of NOLs by a
Loss Corporation that has undergone an Ownership Change. If the Company has an
Ownership Change, the taxable income that the Company can offset with NOLs in
any fiscal year is limited to the value of the Company (excluding nonbusiness
assets if the value of such assets exceeds one-third of total assets) prior to
such Ownership Change multiplied by the federal long-term tax exempt interest
rate. NOLs may be eliminated completely if the Company, after an Ownership
Change, does not continue its historic business nor use a significant portion of
its historic business assets in a new business. These rules are extremely
complex. The application of these rules to the Company depends on facts and
circumstances not known by the Company or beyond the Company's control, or which
encompass future transactions which may or may not be consummated.
 
    The Company monitors all 5-percent Shareholders by tracking reports of
beneficial ownership that such shareholders are required to file with the SEC.
Based upon these records, the Company does not believe that an Ownership Change
has occurred because the percentage of stock (determined on the basis of value)
owned by the Company's 5-percent Shareholders did not increase by more than 50
percentage points from the lowest percentage of stock that was owned by such
5-percent Shareholders at any time over the preceding three-year period. The
Company further believes that the Crescent Transactions will not cause an
Ownership Change. However, there can be no assurance that unrelated
transactions, regardless of whether combined with the Crescent Transactions,
will not cause an Ownership Change.
 
    GOVERNMENT REGULATION.  The Company is subject to federal and state laws
governing financial arrangements between healthcare providers. These laws
generally prohibit certain direct and indirect payments and/or fee-splitting
arrangements between healthcare providers that are designed to induce, are in
exchange for, or encourage patient referrals. The Medicare Law Amendments are
among the most prominent of such laws.
 
    The Medicare Law Amendments prohibit the offering, paying, soliciting or
receiving any form of remuneration in return for referring federal healthcare
patients, or in return for purchasing, leasing, ordering, or arranging for, or
recommending purchasing, leasing or ordering any good, facility, service or item
for which payment may be made under federal healthcare programs. Violations of
the Medicare Law Amendments may result in criminal and civil sanctions,
including exclusion from the Medicare and/or Medicaid programs.
 
                                       38
<PAGE>
    After the Crescent Transactions, the Company will receive from CBHS fixed
Franchise Fees of $81 million, which may increase in certain circumstances (See
"Crescent Transactions--Master Franchise Agreement"). The Company will provide
CBHS with an array of services, including advertising and marketing assistance,
risk management services, outcomes monitoring, consultation with respect to
matters relating to CBHS' business in which the Company has expertise and the
Company's operation of a telephone call center utilizing the "1-800-CHARTER"
telephone number. The Company believes that the Franchise Fee arrangements
described above are consistent with the Medicare Law Amendments because such
arrangements do not involve the Company's referral of patients to CBHS. However,
there can be no assurance that regulatory agencies or private parties will not
challenge the Company based on alleged violations of the Medicare Law
Amendments.
 
    INDENTURE.  After the Closing, Noteholders will have the right to require
the Company to repurchase their Notes at a purchase price equal to 101% of the
principal amount of the Notes, plus accrued and unpaid interest. Noteholders
will have until a deadline specified by the Company, which can be up to 70 days
after the Closing, to make the necessary election. If all Noteholders elect to
exercise the repurchase rights described above, the cost to the Company will be
approximately $378.8 million plus accrued and unpaid interest. The Noteholders
include Huff, which owns approximately 35% of the Notes, and other institutional
investors. The Noteholders acquired $375 million of the Company's notes in a
private placement in 1994, followed by an exchange offering pursuant to which
such notes were exchanged for the Notes, which were registered under the
Securities Act of 1933, as amended, and listed for public trading.
 
    The Company has received a commitment letter from two commercial banks,
which provides a commitment to lend to the Company up to $200 million to
repurchase the Notes. The Company believes that it will have sufficient
liquidity from the proceeds of the Crescent Transactions, internal cash reserves
and anticipated borrowing capacity under the new credit agreement to repurchase
all of the Notes that it could be required to repurchase.

OPINION OF FINANCIAL ADVISOR
 
    On January 29, 1997, Dean Witter delivered its opinion to the Board to the
effect that, subject to certain matters to be stated in its opinion, the
consideration to be received in the Crescent Transactions was fair, from a
financial point of view, to the Company.
 
    THE FULL TEXT OF THE OPINION OF DEAN WITTER DATED JANUARY 29, 1997, IS
ATTACHED AS APPENDIX I AND IS INCORPORATED BY REFERENCE HEREIN. STOCKHOLDERS ARE
URGED TO READ THE OPINION IN ITS ENTIRETY FOR A DESCRIPTION OF THE FACTORS
CONSIDERED AND ASSUMPTIONS MADE BY DEAN WITTER IN RENDERING ITS OPINION.
 
    DEAN WITTER'S OPINION IS DIRECTED TO THE BOARD ONLY AND DOES NOT CONSTITUTE
A RECOMMENDATION TO STOCKHOLDERS AS TO HOW SUCH STOCKHOLDERS SHOULD VOTE ON THE
CRESCENT TRANSACTIONS AT THE ANNUAL MEETING. IN ADDITION, DEAN WITTER WAS NOT
REQUESTED TO OPINE AS TO, AND ITS OPINION DOES NOT ADDRESS, THE UNDERLYING
BUSINESS DECISION OF THE BOARD TO PROCEED WITH OR TO EFFECT THE CRESCENT
TRANSACTIONS.
 
    In arriving at its opinion, Dean Witter, among other things, (i) reviewed
executed copies of the Crescent Transaction Documents; (ii) reviewed the Annual
Reports on Form 10-K and related publicly available financial information of the
Company for the three most recent fiscal years ended September 30, 1996, the
Quarterly Reports on Form 10-Q and related publicly available financial
information of the Company for the three most recent quarterly fiscal periods
ended June 30, 1996, the Company's Proxy Statement, dated January 25, 1996, the
Company's Current Reports on Form 8-K filed from September 30, 1993 through
January 28, 1997, and certain other information, including publicly available
information, relating to the business, earnings, cash flow, assets and prospects
of the Company; (iii) reviewed the Annual Reports on Form 10-K and related
publicly available financial information of CEI for the three most recent fiscal
years ended December 31, 1995, the Quarterly Reports on Form 10-Q and related
publicly available financial information of CEI for the three most recent
quarterly fiscal periods ended September 30, 1996, CEI's definitive Proxy
Statement, dated May 20, 1996, the Prospectus, dated June 18, 1996, and the
Prospectus Supplement dated September 27, 1996, relating to CEI's most recent
common stock offering, CEI's Current Reports on Form 8-K filed since August 2,
1994 through January 28, 1997,
 
                                       40
<PAGE>
and certain other information, including publicly available information,
relating to the business, earnings, cash flow, assets and prospects of CEI; (iv)
reviewed income statement, balance sheet and cash flow forecasts of the Company
and its constituent businesses for the fiscal years ended September 30, 1997 and
1998 as furnished to Dean Witter by the Company; (v) conducted discussions with
members of senior management of the Company concerning the past and current
business, operations, assets, present financial condition and future prospects
of the Company and CBHS; (vi) reviewed the historical reported market prices and
trading activity for the publicly traded securities of the Company and CEI;
(vii) compared certain financial information, operating statistics and market
trading information relating to Magellan and CEI with published financial
information, operating statistics and market trading information relating to
selected public companies that Dean Witter deemed to be reasonably similar to
Magellan and CEI, respectively; (viii) compared the financial terms of the
Crescent Transactions and the Crescent Transaction Documents with the financial
terms, to the extent publicly available, of selected other recent transactions
that Dean Witter deemed to be relevant; and (ix) reviewed such other information
and financial studies and analyses and performed such other investigations and
took into account such other matters as Dean Witter deemed necessary including
Dean Witter's assessment of general economic, market, and monetary conditions.
 
    In preparing its opinion, Dean Witter assumed and relied upon the accuracy
and completeness of all financial and other information supplied to it by the
Company or that was publicly available and did not independently verify such
information. Dean Witter also relied upon the management of the Company as to
the reasonableness and achievability of the financial forecasts of the Company
(and the assumptions and bases thereof) provided to it or prepared on the basis
of information and assumptions furnished to it, and with the Board's consent,
assumed that such forecasts were reasonably prepared on the basis reflecting the
best currently available estimates and judgments of such management as to the
future operating performance of the Company. Dean Witter was not requested to
make, and Dean Witter did not make, an independent appraisal or evaluation of
assets, properties, facilities or liabilities of the Company and it was not
furnished with any such appraisal or evaluation. In addition, the financial and
other terms of the Crescent Transactions were negotiated with Crescent by senior
management of the Company. Dean Witter assumed such negotiations took place at
arm's-length and in form and substance as related to Dean Witter by the Company.
Dean Witter did not, and was not requested by the Company to, participate with
respect to such negotiations. In addition, Dean Witter was not authorized to
solicit, and did not solicit, indications of interest from third parties with
respect to alternative transactions to the Crescent Transactions, including any
sale of Charter.
 
    Dean Witter's opinion was necessarily based upon prevailing market
conditions and other circumstances and conditions as they existed and could be
evaluated as of the date of the opinion.
 
    In connection with advising the Board on January 29, 1997 and in preparing
its written and oral presentations to the Board, Dean Witter performed a variety
of financial and comparative analyses. The material analyses presented by Dean
Witter to the Board at the time are summarized below. The preparation of a
fairness opinion involves various determinations as to the most appropriate and
relevant methods of financial analysis and the application of those methods to
the particular circumstances and, therefore, such an opinion is not readily
susceptible to summary description. Furthermore, in arriving at its fairness
opinion, Dean Witter did not attribute any particular weight to any particular
analysis or factor considered by it, but rather made qualitative judgments as to
the significance and relevance of each analysis and factor. Accordingly, Dean
Witter believes that its analysis and the factors considered, without
considering all analyses and factors, could create a misleading or incomplete
view of the process underlying the opinion. In its analyses, Dean Witter made
numerous assumptions with respect to industry performance, general business and
economic conditions and other matters, many of which are beyond the Company's
and Dean Witter's control. Any estimates contained in Dean Witter's analyses are
not necessarily indicative of actual values, which may be significantly more or
less favorable than as set forth therein. Estimated values do not purport to be
appraisals and do not necessarily reflect the prices at which
 
                                       41
<PAGE>
companies or their securities may be sold in the future and such estimates are
inherently subject to uncertainty.
 
    1.  CONSIDERATION VALUATION.  Dean Witter analyzed the net value of the
consideration the Company is to receive in the Crescent Transactions, which
consists of (a) the sum of (i) the cash payment of $400 million to be received
from Crescent (including, to the extent assumed by Crescent, the value of any
debt assumed by Crescent) and (ii) the value of Magellan's equity interest in
CBHS LESS (b) the value of the Crescent Warrants and (c) taking into
consideration the value attributable to the Retained Franchise Assets.
 
    VALUATION OF THE RETAINED FRANCHISE ASSETS.  Using a discounted cash flow
analysis, Dean Witter valued the Retained Franchise Assets under three operating
scenarios, which differed on the basis of the projected volume of hospital
acquisitions by CBHS. Dean Witter estimated (based on a discount rate of between
17.5% and 12.5%) the Franchise Fee EBITDA to be from between $255.0 million to
$359.0 million under the Base Case, between $282.4 million to $401.3 million
under the Increased Acquisition Scenario and between $252.3 million and $355.3
million under the Decreased Acquisition Scenario.
 
    Dean Witter also analyzed the effect that the possible subordination of the
Franchise Payments to the lease payments would have on the valuation of the Base
Case Franchise Fee EBITDA. In doing so, Dean Witter assigned increasing discount
rates to the Franchise Fee EBITDA, reflecting the risk attributable to the
certainty of the cash flows to be received in connection with the Franchise
Agreements. For purposes of this analysis, Dean Witter discounted the after-tax
Franchise Fee EBITDA associated with the first three percent of CBHS' total
revenues (the Base Franchise Fee EBITDA) by ten percent. Under one scenario,
Dean Witter then discounted the remaining Franchise Fee EBITDA by 18% (with the
higher discount rate utilized to give effect to the possible subordination of
the after-tax franchise fee contribution) which resulted in a discounted present
value, when added to the Base Franchise Fee EBITDA, of $339.8 million. Under a
second scenario, Dean Witter discounted the last $25 million of Franchise Fee
EBITDA to be received in each year by 33% and the remainder (not including the
Base Franchise Fee EBITDA which was discounted at 10%) by 12.5%, which, when
added to the Base Franchise Fee EBITDA, resulted in a discounted present value
of $326.1 million.
 
    Dean Witter did not value the potential incremental future value of
additional revenues that may be generated by the Company's ability to enter into
franchise relationships with other potential franchisees, but took into account
solely the value associated with the franchise relationship with CBHS.
 
    VALUATION OF CBHS.  Using a discounted cash flow analysis, Dean Witter
estimated the present value of the future cash flows that CBHS is projected to
produce over a five-year period, if CBHS were to perform in accordance with the
Company's management projections. Dean Witter estimated the terminal values of
the CBHS equity interest at the end of a five-year period using terminal
multiples of 2001 EBITDA ranging from 4.0x to 8.0x and discounted such terminal
values back to present values at different discount rates ranging from 12.50% to
17.50% based upon a consideration of a number of factors, including cost of
capital, required rates of return to investors and risks attributable to
uncertainty of the projected cash flow. Based on such analyses, the discounted
present value of the sale value for 100% of CBHS based on discounted cash flows
ranged from $13.0 million to $50.2 million.
 
    VALUATION OF THE WARRANTS.  Using the Black-Scholes method of option
valuation, Dean Witter valued the individual Warrants and estimated the
cumulative value of the Warrants to be in the range of $22.21 million to $24.75
million. Among the assumptions incorporated into the Black-Scholes method by
Dean Witter for its calculations were the estimated value of the underlying
shares, the warrant exercise price, the duration of the Warrants, and the
volatility of the underlying shares. Dean Witter also reviewed the terms of the
Warrant Purchase Agreement to determine the effect such agreement had on the
value of the Warrants.
 
                                       42
<PAGE>
    Based on the above valuation ranges, Dean Witter calculated the total value
of the consideration to be received by the Company in the Crescent Transactions
(that is, the cash payment ($400 million) PLUS the value of the CBHS Interest
MINUS the value of the Warrants and taking into account the value attributable
to the Retained Franchise Assets) to be between $790.0 million to $665.0
million. Based on a projected fiscal year 1997 adjusted EBITDA of $132.7 million
minus corporate overhead expenses attributable to Charter, Dean Witter
calculated a range of implied multiples of 1997 EBITDA to the aggregate
consideration to be received by the Company in the Crescent Transactions of
between 6.0x to 5.0x.
 
    2.  ANALYSIS OF COMPARABLE TRANSACTIONS.  Dean Witter analyzed certain
recent asset sales involving psychiatric services providers, focusing
particularly upon psychiatric hospital sales. There were a total of fifteen
comparable transactions that Dean Witter analyzed since 1994. Such analysis
indicates the ratio of aggregate price to EBITDA for the publicly reported LTM
for these transactions ranged from 2.38x to 9.24x with a mean of 5.61x and an
adjusted mean of 5.54x (adjusted by excluding the high and low figures). Based
on its review of the foregoing range of multiples, its consideration of
Magellan's and Charter's financial and operating characteristics and the
relevance of the foregoing range in light of such characteristics, as well as
its experience in the health care industry, Dean Witter identified the four
transactions which Dean Witter deemed to be the most comparable transactions to
the Crescent Transactions consisting of Behavioral Healthcare Corporation's
acquisition of certain psychiatric facilities from Community Psychiatric
Centers, Behavioral Healthcare Corporation's acquisition of certain psychiatric
facilities from Mental Health Management, the Company's acquisition of certain
psychiatric hospitals from National Medical Enterprises and an acquisition of
psychiatric facilities involving solely private companies, which transactions
included the three most recent transactions. For these four transactions the
price to LTM EBITDA ratios ranged from 3.90x to 5.58x with a mean of 5.01x.
Applying these multiple results in an implied valuation range of the EBITDA
being transferred in the Crescent Transactions (based upon 1996 EBITDA of $133.4
million) of between $520.3 million and $744.4 million, with a mean of $664.8
million, compared with the valuation range established by analysis of the
consideration itself of $665 million to $790.0 million. Dean Witter observed
that applying these multiples to fiscal year 1996 EBITDA for Charter would
result in a range of values comparable to the valuation range of the aggregate
consideration to be received by the Company.
 
    No company or transaction used as a comparison in the above analysis is
identical to the Company or the Crescent Transactions, respectively.
Accordingly, analysis of the results of the foregoing is not mathematical;
rather it involves complex considerations and judgments concerning the
difference in financial and operating characteristics and terms and structure of
the Company and the Crescent Transactions, respectively, and other factors that
could affect the public trading values of the companies to which the Company was
compared.
 
    3.  PRO FORMA ACCRETION/DILUTION ANALYSIS.  Dean Witter developed a pro
forma analysis of the restructured company reflecting the effects of the
Crescent Transactions. This analysis assumed (i) that the Crescent Transactions
were consummated on October 1, 1996, (ii) a rate of return on the net cash
proceeds to be received by the Company from the Crescent Transactions of 10% and
(iii) an immediate redeployment of such net cash proceeds. On the basis of such
analysis, Dean Witter observed that the Crescent Transactions, on a pro forma
basis, would be accretive by 5.7% and 3.2% in fiscal 1997 and 1998,
respectively, and dilutive by 0.8% in fiscal 1999.
 
    Dean Witter is a recognized investment banking firm with substantial
experience in transactions similar to the Crescent Transactions and is familiar
with the Company and its businesses. As part of its investment banking business,
Dean Witter is regularly engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, private placements, secondary distributions of listed and
unlisted securities, and valuations for corporate and other purposes. The Board
selected Dean Witter because of its expertise, reputation and familiarity with
the psychiatric services industry.
 
                                       43
<PAGE>
    As compensation for its financial advisory services in connection with the
Crescent Transactions, Dean Witter will receive a fee of approximately $3.0
million from the Company upon the Closing. Dean Witter received a fee of
$500,000 upon delivery of its opinion, which will be credited against the $3.0
million fee described above. Whether or not the Crescent Transactions are
consummated, the Company has agreed to reimburse Dean Witter for travel and
out-of-pocket expenses incurred by Dean Witter, including the reasonable fees
and disbursements of counsel. The Company has also agreed to indemnify Dean
Witter and certain related persons against certain liabilities to which Dean
Witter may become subject as a result of its engagement, including liabilities
under the federal securities laws.
 
    Dean Witter regularly publishes research reports regarding the psychiatric
services industry and the REIT industry and has previously published research
regarding the Company and CEI. Dean Witter has in the past provided financial
advisory and financing services to the Company and CEI (acting as a co-manager
for CEI public offerings) and has received customary fees. In the ordinary
course of its business, Dean Witter trades Common Stock and common stock of CEI
for its own account and for the account of its customers and may at any time
hold a long or short position in such securities.
 
INTERESTED PARTIES
 
    Richard E. Rainwater and certain of his affiliates and associates have a
significant interest in Crescent and the Company. Set forth below is a summary
of the interests of such persons.
 
    CRESCENT.  Crescent is the operating partnership of CEI. The officers of CEI
include Richard E. Rainwater, Chairman of the Board of Directors, John C. Goff,

    Mr. Haddock owns 57,084 shares of Common Stock and a portion of the
Rainwater-Magellan Warrant which gives Mr. Haddock the right to purchase an
additional 28,542 shares of Common Stock.
 
                                       44

    Mr. Goff and Goff Family, L.P. own, respectively, 51,376 and 5,708 shares of
Common Stock and portions of the Rainwater-Magellan Warrant which gives Mr. Goff
and Goff Family, L.P., respectively, the right to purchase an additional 25,688
and 2,854 shares of Common Stock. Goff Capital, Inc. is the sole general partner
of Goff Family, L.P. Mr. Goff and his spouse own 100% of the capital stock of
Goff Capital, Inc. Mr. Goff has sole voting and dispositive power over the
shares of Common Stock owned by Goff Family, L.P. and the shares of Common Stock
underlying Rainwater-Magellan Warrant owned by Goff Family L.P. As a result of
such relationships, Mr. Goff is deemed to be the beneficial owner of such shares
of Common Stock and shares of Common Stock underlying the Rainwater-Magellan
Warrant.
 
    The Rainwater-Magellan Warrant entitles the holders to purchase in the
aggregate, at any time prior to its January 25, 2000 expiration date, up to
2,000,000 shares of Common Stock at a purchase price of $26.15 per share. The
Private Placement Agreements provide, among other things, for the adjustment of
the number of shares of Common Stock that can be purchased under the
Rainwater-Magellan Warrant and the purchase price, respectively, for certain
dilutive events, for registration rights for the shares of Common Stock owned by
Rainwater-Magellan, including those underlying the Rainwater-Magellan Warrant
(which registration rights, as mentioned below, have been exercised), and for a
variety of other customary provisions, including, without limitation, certain
restrictions on Rainwater-Magellan's private sale of such shares, certain
preemptive rights of Rainwater-Magellan to acquire additional securities issued
by the Company for cash in a private placement transaction (which have been
waived to the extent they may apply to the Crescent Transactions), and
standstill covenants restricting the purchase of additional shares of Common
Stock by Rainwater-Magellan and its affiliates in certain circumstances.
 
    Darla D. Moore, a director of the Company, is the spouse of Richard E.
Rainwater. Under the terms of the Private Placement Agreements,
Rainwater-Magellan has the right to designate a nominee acceptable to the
Company for election as a director of the Company for so long as the Rainwater
Group continues to own beneficially a specified minimum number of shares of
Common Stock. Rainwater-Magellan proposed Ms. Moore as its nominee for director,
and Ms. Moore was elected a director by the Board in February 1996. Because of
her relationship to Mr. Rainwater and the Rainwater Group, Ms. Moore has not
participated in any Board action taken with respect to the proposed Crescent
Transactions.
 
    As of March 31, 1997, Rainwater-Magellan beneficially owned 5,828,828 shares
of Common Stock (including the 1,942,996 shares which can be purchased under the
Rainwater-Magellan Warrant), which represented in the aggregate 19.0% of the
Common Stock.
 
    Under the terms of the Private Placement Agreements, the Company agreed (i)
to pay a transaction fee of $150,000; (ii) to reimburse certain expenses of
Rainwater, Inc. in connection with the Private Placement; (iii) to pay the
Rainwater Group an annual monitoring fee of $75,000 commencing on March 31,
1996; and (iv) to reimburse the Rainwater Group for reasonable fees and expenses
(up to a maximum of $25,000 annually) incurred in connection with its ownership
of the Common Stock and the Rainwater-Magellan Warrant. The Company also agreed
under the Private Placement Agreements to reimburse the Rainwater Group in the
future for one additional filing under the HSR Act if an HSR Act filing is
required in connection with an exercise of the Rainwater-Magellan Warrant.
 
    Rainwater-Magellan purchased the Common Stock and the Rainwater-Magellan
Warrant on January 25, 1996. From that date through December 31, 1996, the
Company paid to the Rainwater Group under the Private Placement Agreements an
aggregate of $306,344, consisting of a transaction fee of $150,000, expense
reimbursement in connection with the Private Placement of $86,156, and
monitoring fees and expenses of $70,188. Excluded from these amounts are
directors' fees and expense reimbursement paid to Ms. Moore in her capacity as a
director of the Company. The Company also incurred costs of approximately
$55,000 in connection with its registration of the Shares and expects to incur
approximately $40,000 in costs to register the shares of Common Stock underlying
the Rainwater-Magellan Warrant.

    E. MAC CRAWFORD.  Under the Company's Employment Agreement with Mr.
Crawford, Mr. Crawford will be paid a contract bonus in the amount of $2.475
million if the Crescent Transactions are closed. In addition, Mr. Crawford has
received a grant under the 1997 Plan, subject to stockholder approval, for the
purchase of 750,000 shares of Common Stock. Under the terms of Mr. Crawford's
employment agreement with the Company, if stockholders do not approve the 1997
Plan, Mr. Crawford will be entitled to resign (at any time until the expiration
of the Employment Agreement on February 28, 2000) and receive, in addition to
accrued salary and bonus, a payment in the amount of $4.125 million (subject to
a gross-up for certain excise taxes). See "Compensation Committee Report on
Executive Compensation--Employment Agreements and Change of Control Provisions."
 
    CERTAIN EMPLOYEES.  Each of the Named Executive Officers and certain other
officers and key employees of the Company and its subsidiaries have been awarded
options under the 1996 Stock Option Plan. The 1996 Plan provides that the
options granted thereunder vest and become exercisable over four years from the
date of grant, except that upon the occurrence of certain events the options
immediately vest and become fully exercisable. One such event is the "sale,
lease, transfer or other disposition . . . of all or substantially all" of the
Company's assets. Based upon a review of relevant Delaware case law, the Company
believes that substantial uncertainty exists regarding whether the Crescent
Transactions constitute a "sale . . . of all or substantially all" of the
Company's assets. Accordingly, the Board has determined to treat the Closing as
such an event in order to eliminate the risk of a dispute. Therefore, a total of
1,210,375 options will vest under the 1996 Plan immediately as a result of the
Closing. The persons who hold options that will immediately vest as a result of
the Closing and the number of such options held by such persons are as follows:
Messrs. Crawford (225,000 options); McKnight (68,750 options); Davis (130,000
options); Harbin (75,000 options) and all others (711,625 options). See
"Compensation Committee Report on Executive Compensation--Employment Agreements
and Change of Control Provisions."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The following is a general discussion of the material federal income tax
consequences to the Company and United States stockholders of the consummation
of the Crescent Transactions. The general discussion below sets forth the
material federal income tax consequences to the Company on a consolidated basis
of the Crescent Transactions assuming the IRS respects the Crescent
Transactions, including the allocation of the total consideration to be received
by the Company as a result of the Crescent Transactions. As in any transaction,
there exists some risk that the IRS will successfully recharacterize or
reallocate certain items of income, deduction, gain, or loss realized with
respect to the Crescent Transactions. In addition to the discussion contained
below, the consummation of the Crescent Transactions may result in a variety of
state, local or foreign income, franchise, transfer or other taxes. This
discussion is applicable only to those stockholders who are citizens or
residents of the United States for United States tax purposes and to domestic
corporations. This discussion is not applicable to Common Stock acquired as
compensation, including shares acquired upon the exercise of options, shares
acquired pursuant to restricted stock agreements with the Company, or shares
held under the Company's employee benefit plans. The Company will not request a
private letter ruling from the IRS with regard to any matters discussed in this
section or any other matters pertaining to the Crescent Transactions.
 
    The following discussion is based upon the provisions of the Code in effect
as of the date hereof, Treasury Regulations, reported judicial decisions and
current published administrative rulings and procedures. It is impossible to
predict how subsequent developments in tax legislation, case law, Treasury
Regulations or administrative interpretations may affect taxation of the
Crescent Transactions, the Company or its stockholders. Consequently, it is
emphasized that no assurance can be given that additional legislative, judicial
or administrative changes will not be forthcoming that would modify any portion
of the following discussion, nor is there any assurance that the tax
consequences to the Company and its stockholders will continue as herein
described. Furthermore, because certain of the tax consequences discussed below
will be directly or indirectly dependent upon facts and circumstances not
currently known,
 
                                       46
<PAGE>
it is also emphasized that no assurance can be given that the issues discussed
below will not be challenged by the IRS or, if so challenged, will be decided
favorably to the Company, or that the actual federal income tax consequences to
the various parties will be as discussed below.
 
    EFFECT ON THE COMPANY'S UNITED STATES STOCKHOLDERS.  Because the Crescent
Transactions do not involve the sale or exchange of Common Stock, or the
distribution of cash or property, United States stockholders of the Company will
not realize any federal income tax consequences resulting from the Crescent
Transactions.
 
    EFFECT OF SALE OF ASSETS TO CRESCENT.  The sale of the Purchased Facilities
held, directly or indirectly, by the Company will be treated as taxable
dispositions by its subsidiaries of the assets thereof. The Company expects to
recognize an aggregate net gain for federal income tax purposes. Gain will be
recognized equal to the excess of the amount realized (which includes
liabilities assumed by Crescent and property subject to liabilities) for the
asset over the Company's adjusted tax basis in such asset immediately prior to
the sale. Loss will be recognized equal to the excess of the Company's adjusted
tax basis in such asset over the amount realized (which includes liabilities
assumed by Crescent and property subject to liabilities) for the asset
immediately prior to the sale, assuming the related party loss rules do not
apply to the Crescent Transactions. The related party loss rules prohibit or
defer the deduction of losses on the sale or exchange of property if the
transaction is directly or indirectly between related parties which include (i)
two corporations that are members of the same controlled group or (ii) a
corporation and a partnership if the same persons own more than fifty percent in
value of the outstanding stock of the corporation, and more than fifty percent
of the capital or profit interest in the partnership. The Company does not
anticipate that the related party loss rules will prohibit or defer any
deduction of losses on the Crescent Transactions.
 
    TRANSFER OF PROPERTY TO CBHS.  CBHS will be taxed as a partnership for
federal income tax purposes. Generally, no gain or loss is recognized by a
partnership or its partners as a result of a contribution of property in
exchange for an interest in the partnership. However, gain may be recognized if
liabilities of the contributing partners are assumed or the contributed property
is taken subject to liabilities. In addition, gain will be recognized if the
contribution is, in whole or in part, deemed to be a sale. The Company
anticipates that no gain or loss will be recognized by the Company or CBHS upon
the transfer of property and intangible rights held, directly or indirectly, by
Charter or its subsidiaries to CBHS, in exchange for the CBHS Interest. The
Company anticipates that it will recognize taxable gain on the sale of certain
tangible personal property to CBHS.
 
    The basis of each item of property and intangible rights transferred by
Charter or its subsidiaries to CBHS differs from its value. The Code requires
that income, gain, loss and deductions with respect to such contributed property
be allocated among the members of CBHS so as to take account of the variation
between the basis of the property to CBHS and its fair market value at the time
of contribution. Thus, the economic consequences to the members of CBHS should
be unaffected by the fact that the tax basis of the contributed property differs
from its fair market value, although the tax consequences relating to such
difference will be allocated, to the extent possible, to the contributing
members of such property to CBHS.
 
    FRANCHISE AGREEMENT.  The Company will recognize ordinary income for the
Franchise Fees payable pursuant to the Master Franchise Agreement.
 
    WARRANTS.  No tax gain or loss will be realized by the Company upon the
issuance of Warrants to Crescent.
 
    NET OPERATING LOSS CARRYFORWARDS.  See "Crescent Transactions--Risk Factors,
Net Operating Loss Carryforwards."
 
                                       47

ACCOUNTING TREATMENT
 
    The Crescent Transactions will result in (i) a sale of assets by the Company
to Crescent, (ii) the deconsolidation of the net assets and results of
operations of Charter from the financial statements of the Company, (iii) the
contribution of certain assets to CBHS and the assumption of certain liabilities
by CBHS in exchange for the CBHS Interest and (iv) a sale by the Company of
certain assets relating to its information services subsidiary to CBHS. Any loss
recognized by the Company as a result of the Crescent Transactions will be
included in the Company's consolidated financial statements as part of
continuing operations for the period during which the Crescent Transactions are
consummated. Any portion of the loss incurred by the Company relating to the
early extinguishment of debt, including any Notes tendered, will be classified
as extraordinary items for financial reporting purposes. The Company's
investment in CBHS will be accounted for under the equity method of accounting.
 
    THE FOLLOWING SUMMARIES OF THE CRESCENT TRANSACTION DOCUMENTS ARE QUALIFIED
IN THEIR ENTIRETIES BY THE COMPLETE TEXT OF THE CRESCENT TRANSACTION DOCUMENTS,
WHICH HAVE BEEN FILED AS EXHIBITS 2(A)-(C), 4(A) AND 99(B)-(H) TO THE COMPANY'S

INCORPORATED HEREIN BY REFERENCE.
 
CRESCENT PURCHASE AGREEMENT
 
    ASSETS TO BE SOLD.  Magellan will sell to Crescent the Purchased Facilities
and the fixtures, furniture and equipment owned by Charter and used in the
Facilities. The Purchased Facilities include 83 behavioral healthcare facilities
and related medical office buildings. Crescent will also purchase related

actuarially adequate to cover insurance risks. The Company also covenants that
it will not directly or indirectly induce or attempt to influence any key
employee of Crescent to leave such employee's position except as mutually agreed

each hospital owned or operated by a joint venture, pursuant to which CBHS will
perform, to the extent possible, all of the Company's obligations under the

    INDEMNIFICATION.  The Company agrees to indemnify Crescent for pre-Closing
debts, liabilities and obligations not expressly assumed by Crescent and
breached representations, warranties and covenants. Crescent agrees to indemnify
the Company against post-Closing debts, liabilities and obligations relating to
the Purchased Facilities (following the assumption by Crescent of the operation
of the Purchased Facilities) and breach of representations, warranties and
covenants. Indemnification for debts, liabilities and obligations will survive
until expiration of the applicable statutes of limitation and will not be
subject to any cap or threshold limitations. Indemnification for breach of
warranties and covenants will survive until expiration of the applicable
statutes of limitation and will not be subject to limitation provided that (i)
for a period of two years following the Closing, the breaching party will not be
obligated to pay any amounts until the aggregate claims exceed $1 million, at
which time the breaching party becomes obligated to pay all claims, and (ii)
thereafter the breaching party will not be obligated to pay any amounts until
the aggregate claims exceed $10 million, at which time the breaching party
becomes obligated to pay all claims.
 
    TERMINATION.  Either the Company or Crescent may (i) terminate or (ii) waive
and close, in the event certain conditions to closing are not satisfied. The
Company and Crescent remain liable to the other for all damages suffered by the
other if the unsatisfied condition was due to its breach of any of its
covenants, representations or warranties in the Crescent Purchase Agreement. The
Company intends to recirculate proxy materials and resolicit its stockholders in
the event material conditions to closing are waived by the Company.
 
CBHS CONTRIBUTION AGREEMENT
 
    At the Closing, the Company will enter into the CBHS Contribution Agreement.
 
    ASSETS TO BE CONTRIBUTED.  The CBHS Contribution Agreement provides that the
Company will cause to be contributed to CBHS (or a subsidiary thereof) in
consideration for the CBHS Interest the following assets related to the
Purchased Facilities and to certain leased facilities operated by subsidiaries
of the Company: patient medical records; licenses and permits used in the
operation of the Facilities, to the extent that such licenses and permits are
transferable; leasehold interests, as lessee, in the Leased Facilities specified
in the CBHS Contribution Agreement; leasehold interests as lessee in certain
medical office buildings specified in the CBHS Contribution Agreement and
certain other assets and contracts specified in the CBHS Contribution Agreement.
 
    The CBHS Contribution Agreement provides that Crescent will make an initial
cash contribution to CBHS in the amount of $5 million.
 
    ASSETS TO BE SOLD.  The Contribution Agreement provides that CBHS will
purchase from subsidiaries of the Company (i) certain assets relating to the
Company's information systems subsidiary for $5 million; and (ii) the following
assets related to the Facilities and certain other facilities as such assets
exist at the Closing: supplies and inventory, notes receivable, prepaid assets
and expenses, lease deposits and utility deposits for $8 million, subject to a
post-Closing adjustment. The post-Closing adjustment will be measured by
comparing the net book value of the assets described above at the Closing to $8
million, which is the amount to be paid by CBHS to Magellan at the Closing. The
post-Closing adjustment is expected to be finalized within six months of the
Closing.
 
    EXCLUDED ASSETS.  The Company will not contribute the following assets to
CBHS: (i) the assets that will be sold to CBHS (as described above); (ii)
capital stock of any subsidiary of the Company (except Charter Medical Executive
Corporation) and corporate minute books, stock ledgers and records relating to
the organization and capitalization of such subsidiaries; (iii) all rights,
properties and assets used by the Company or any of its subsidiaries primarily
in a business other than in the operation of the Facilities and the delivery of
behavioral healthcare in connection therewith; (iv) all assets disposed of by
the Company prior to the date of the CBHS Contribution Agreement or prior to the
Closing in the ordinary course of business; (v) trademarks, trade names,
corporate names and logos owned by the Company and any of its
 
                                       51
<PAGE>
subsidiaries; (vi) all real estate, furniture, fixtures and equipment sold to
Crescent pursuant to the Crescent Purchase Agreement; (vii) any deferred tax
assets of a subsidiary of the Company at the Closing; (viii) protocols, and
future improvements and modifications thereof; (ix) policy and procedure
manuals, and future improvements thereof; (x) all cash, cash equivalents,
short-term investments, marketable securities and accounts receivable; (xi)
patient related software systems; (xii) TRIMS system; (xiii) purchasing/ordering
systems; (xiv) accounting systems; (xv) the "1-800-CHARTER" call center system;
(xvi) intellectual property rights; (xvii) tax refunds, cost report adjustments
and settlements relating to periods prior to the Closing; (xviii)
disproportionate share payments and (xix) assets necessary for the provision of
the services to be provided by the Company pursuant to the Master Franchise
Agreement.
 
    LIABILITIES TO BE ASSUMED.  The CBHS Contribution Agreement provides that
CBHS will assume all debts, obligations, duties and liabilities relating to or
arising out of the operation of the Facilities and business related thereto
after the Closing, including obligations that require performance after the
Closing, liabilities and obligations relating to the assets contributed to CBHS
and liabilities relating to employee accrued vacation time and sick days.
 
    PURCHASE PRICE.  The purchase price for the assets sold to CBHS by the
Company is $13 million, subject to post-Closing adjustments, which is equal to
the net book value of such assets, less the sum of the obligations assumed by
CBHS pursuant to the CBHS Contribution Agreement. At the Closing, CBHS will pay
to the Company cash in an amount equal to such purchase price.
 
    REPRESENTATIONS AND WARRANTIES.  The Company makes several representations
and warranties to Crescent in the CBHS Contribution Agreement, including among
others, representations as to: (i) the corporate organization and status of the

    At the Closing, the Company will either (i) provide CBHS with bridge
financing for a one-year term in the maximum amount of $55 million, secured by
CBHS receivables, to fund CBHS' anticipated working capital needs during its

of approximately $8 million (See "Crescent Transactions-Loan and Security
Agreement"); or (ii) provide a guarantee, under certain circumstances, not to
exceed $65 million, for a CBHS bank line of credit secured by CBHS' receivables.
CBHS has received a loan commitment from a group of commercial banks to provide

facility.
 
    CBHS agrees in the CBHS Contribution Agreement to pay to the Company all
amounts actually received by CBHS in payment of receivables relating to the
operation of the Purchased Facilities and related operations prior to the
Closing for a fee payable by the Company equal to 5% of the collected
receivables. Any receivables remaining uncollected 120 days after the Closing
will be turned over to the Company at its request.
 
    The respective obligations of Crescent and the Company are subject to, among
other things, the following conditions: (i) satisfaction of all conditions to
closing in the Crescent Purchase Agreement;

and obligations not expressly assumed by CBHS (other than assumed liabilities
that are covered by insurance) and breached representations, warranties and

and obligations relating to the Facilities or liabilities assumed by CBHS.
Provisions relating to survivorship of indemnity obligations, thresholds and
limitations are comparable to those contained in the Crescent Purchase
Agreement.
 
    TERMINATION.  Each of the Company and Crescent has the right to (i)
terminate or (ii) to waive and close in the event representations and warranties
in the CBHS Contribution Agreement are not true at Closing or if any conditions
to closing are not satisfied.
 
CBHS OPERATING AGREEMENT
 
    MEMBER SHARES AND CONTRIBUTIONS.  The Company will make a $5.0 million
capital contribution to CBHS, in the form of certain assets relating to or used
in the operation of the Facilities, and will receive a 50% interest in CBHS. COI

additional $2.5 million in cash to the capital of CBHS within five days after

allocated to the Company and COI in proportion to their percentage interests in
CBHS after giving effect to any special allocations in order to comply with
applicable regulations under the Code. Income, gain, loss and deductions with
respect to any property contributed to the capital of CBHS will, in accordance
with Section 704(c) of the Code, be allocated between the Company and COI so as
to take account of any variation between the adjusted basis of such property to
CBHS and its initial adjusted basis for United States federal income tax
purposes.
 
    DISTRIBUTIONS.  CBHS' available cash will be distributed to the Company and
COI, in such amounts and at such times as determined by CBHS' governing board,
in proportion to their respective percentage interest in CBHS. No distribution
of cash will be made unless rent due under the Facilities Lease and fees due
under the Master Franchise Agreement are fully paid in the year of any
distribution. The Company and COI authorize CBHS to withhold or pay on their
behalf any amount of taxes that CBHS' governing board determines that CBHS is
required to withhold or pay with respect to any amount distributable to the
Company or COI pursuant to the CBHS Operating Agreement, which amounts will
constitute a loan by CBHS for which the Company and COI grant to CBHS a security
interest in their percentage interest in CBHS.
 
    MANAGEMENT.  The management of CBHS will be vested in a four-member
governing board with the Company and COI each designating two individuals as
directors. Each director will have one vote and
 
                                       53

except in the event of certain decisions described below, CBHS' governing board
will act by the affirmative vote of a majority of the directors.
 
    No officer or employee of CBHS will have any authority to cause or permit

80% of CBHS' governing board. The decisions that require 80% board approval

annual budget; (ix) incurring certain indebtedness or granting certain security

president; and (xv) the decision to renew the Facilities Lease or any Franchise
Agreement (Master or Subsidiary).
 
    The CBHS Operating Agreement contains provisions (i) requiring the
preparation of an annual budget and regular meetings of the CBHS' governing
board; (ii) setting forth CBHS' governing board's powers; and (iii) governing
the activities of directors and transactions with affiliates. The CBHS Operating
Agreement also sets forth the initial officers of CBHS. CBHS is required to
indemnify any director relating to liability or damage incurred in connection
with the Business. COI and the Company agree that if the Franchise Fees are past
due, the Company will have the right to prohibit CBHS from taking certain
actions and will have certain remedies (See "Crescent Transactions--Master
Franchise Agreement").
 
    ROLE OF MEMBERS.  The Company and COI will not have any right or power to
take part in the management or control of CBHS in any way, except to the extent
set forth in the CBHS Operating Agreement. The Company and COI will only have
voting rights with respect to matters specifically reserved for their vote in
the CBHS Operating Agreement and each will have one vote for each percentage
interest in CBHS. The CBHS Operating Agreement also contains provisions relating
to CBHS member meetings. No action by CBHS may be taken in connection with the

decree or order of a court, or any other debt, obligation or liability of CBHS
solely by reason of being a member of CBHS.
 
    TRANSFERS.  Except for certain transfers permitted in the CBHS Operating
Agreement under certain conditions, a CBHS member may not transfer all or any
portion of their interest in CBHS. Permitted transfers include transfers to (i)
a wholly owned subsidiary; (ii) the transferor's administrator or trustee if
transferred involuntarily by operation of law; (iii) any transferee if the
transfer is approved by all CBHS members having a 20% or greater interest in
CBHS; (iv) in the case of COI , to a single transferee if necessary for CEI to

                                       54
<PAGE>
person upon compliance with the right of first refusal provision in the CBHS
Operating Agreement. In the event a CBHS member has a binding offer from an
unrelated person for the transfer of its interest in CBHS, other than pursuant
to the permitted transfers described above, the non-selling CBHS member and, in
the event there are more than two CBHS members, CBHS, will have a right of first
refusal to purchase all of the selling CBHS member's interest. In the event that
the Company's or COI's percentage interest in CBHS decreases to less than 25%,
(i) the other party may not transfer its CBHS interest without allowing the
other CBHS members to sell to the proposed transferee, on the same terms and
conditions, their CBHS interests; and (ii) the other party may require the other
CBHS members to sell their CBHS interest to a proposed transferee, on the same
terms and conditions, their CBHS interests.

exist if the governing board will be unable to reach agreement by the required
vote at two successive meetings on (i) a decision requiring 80% board approval;
(ii) a decision involving the expenditure of more than an amount to be
specified; or (iii) a decision relating to the election of executive officers.
The CBHS Operating Agreement contains provisions requiring CBHS' members, CBHS'
governing board and chief executive officers of the Company and COI to use their
best efforts to resolve a deadlock. In the event of a failure to resolve a
deadlock pursuant to these procedures, either the Company or COI will be
authorized to offer to purchase all of the interest of the other, and the
non-offering member must either sell on the offered terms or purchase the
offering member's interest on such terms.
 
LOAN AND SECURITY AGREEMENT
 
    LINE OF CREDIT.  The Company agrees to extend a line of credit in the
principal amount of up to $55 million in favor of CBHS for up to one year after

    ASSIGNMENT.  CBHS has the right to assign its rights under the Master
Franchise Agreement only (i) with the consent of the Company (which consent may
not be unreasonably withheld, conditioned or delayed); (ii) to an entity which
simultaneously acquires all or substantially all of CBHS' business and assets,
provided, in each instance that such assignee also acquires or assumes CBHS'
rights and obligations under the Facilities Lease; or (iii) if the Facilities
Lease is terminated as a result of an event of default thereunder, and Crescent
elects to assume all CBHS obligations under the Master Franchise Agreement and
all other agreements specified in the Facilities Lease, to Crescent or a
designee of Crescent. The Company has the right to assign its obligations under
the Master Franchise Agreement with the prior written consent of CBHS and
Crescent, which consent may not be unreasonably withheld, or to an entity which
simultaneously therewith acquires all or substantially all of the Company's
business and assets.
 
    In the event the Master Franchise Agreement is assigned to Crescent as a
result of the early termination of the Facilities Lease upon an event of
default, the Company may thereafter terminate the Master Franchise Agreement and
all of Crescent's rights thereunder for "good cause," which includes the
assignee's insolvency or bankruptcy; violation of any transfer and assignment
provision contained in the Master Franchise Agreement; the assignee's
noncompliance with any law, rule or regulation applicable to operation of its
business (subject to reasonable attempts to cure); material violations of
confidentiality or nondisclosure covenants; the assignee's failure to perform or
breach of any covenant, obligation, term, condition, warranty or certification
in the Master Franchise Agreement (subject to reasonable cure periods); and the
assignee's failure to pay certain fees owed to the Company under the Master
Franchise Agreement within ten days.

redemptions of any interest in CBHS except that CBHS will have the right to make
cash distributions as long as no default has occurred and is continuing in the
payment of any amount due from CBHS to the Company pursuant to the Master
Franchise Agreement and as long as, after giving effect to the payment of the
distribution, sufficient working capital is available through the payment of
annual continuing fees under the Master Franchise Agreement and budgeted
operating expenses for the three full calendar months following the day of
payment of such distribution; (iv) acquire material assets or any other business
or make any material loans, advance or extension of credit to any other person,
including investments acquired in exchange for stock or other securities, or
create or participate in the creation of any subsidiary or joint venture; (v)

lease, transfer or otherwise dispose of all or any substantial part of its

salaries, bonuses or any other compensation from that set forth in the annual
budget in effect at the time the Company sells its interest in CBHS payable to
the officers, directors or other highly compensated employees; (vii) amend the

engage in any material transaction with Crescent, any affiliate of Crescent or
any affiliate of CBHS other than pursuant to contracts or ongoing arrangements
existing at the time the Company sells its interest in CBHS; (viii) fail to
operate its business activities in substantially the manner such activities are
conducted on the date the Company sells its interest in CBHS or make any
material change in the nature of its business or enter into any material
contract that is not the ordinary course of CBHS' business; and (ix) dissolve,
liquidate or seek bankruptcy or insolvency protection.
 
    INDEMNIFICATION.  In the Master Franchise Agreement (i) CBHS agrees to
indemnify and defend the Company from all losses and liabilities arising
directly or indirectly as a result of, arising out of or in connection with the
operation of CBHS' business, except those directly resulting from the Company's
willful misconduct or fraud and (ii) the Company agrees to indemnify CBHS from
all losses and liabilities arising directly or indirectly as a result of,
arising out of or in connection with the operation of CBHS' business, arising
from the Company's willful misconduct or fraud.
 
    TERM - TERMINATION.  The initial term of the Master Franchise Agreement is
12 years. CBHS has the right to renew the Master Franchise Agreement for four
additional five-year renewal terms, provided that at the end of the initial term
and each renewal term, the fees will be adjusted to reflect the fair market
value of the franchise utilized by the Facilities as of the renewal date for the
then-applicable renewal term. The Master Franchise Agreement includes an
appraisal mechanism for determining fair market value franchise fees.
Notwithstanding the foregoing, (i) if the fair market value franchise fee as so
determined is not acceptable to the Company, then the Company will have the
option to terminate the Master Franchise Agreement at the end of the
then-current term and the Master Franchise Agreement will not be further
extended. Except as provided above the Company will not have the right to
terminate the Master Franchise Agreement (whether for breach or otherwise)
without the consent of CBHS and Crescent.
 
    CBHS will not have the right to terminate the Master Franchise Agreement
(whether for breach or otherwise) without the consent of the Company and
Crescent.
 
    DISPUTE RESOLUTION.  Disputes will be subject to resolution by arbitration

SUBSIDIARY FRANCHISE AGREEMENT
 
    GRANT OF FRANCHISE.  Each Subsidiary Franchise Agreement will be between one
of the CBHS subsidiaries (each a "franchisee") that operates a Facility and the
Company.
 
    Each franchisee will be granted the right to engage in the business of
providing behavioral healthcare utilizing the "CHARTER" System from facilities
in the territory defined in the Subsidiary Franchise Agreement. Each franchisee
will agree to use its commercially reasonable best efforts to operate the
franchised business. The behavioral healthcare business covered by each
Subsidiary Franchise Agreement
 
                                       60
<PAGE>
will be the "Hospital/RTC Based Behavioral Healthcare Business" which is defined
as the business of the operation of an acute care psychiatric hospital, part of
an acute care general hospital operating an acute care psychiatric unit, a
behavioral healthcare residential treatment center, a part of a facility
operating a behavioral healthcare residential treatment center, or other similar
facility providing 24-hour behavioral healthcare and the delivery of behavioral
healthcare from such facility or other affiliated facilities; such behavioral
healthcare to include inpatient hospitalization, partial hospitalization
programs, outpatient therapy, intensive outpatient therapy, residential
treatment, ambulatory detoxification, behavioral modification programs and
related services. The "CHARTER" System is a system for the operation of
Hospital/ RTC Based Behavioral Healthcare Businesses under the "CHARTER" names
and marks, which system includes the right to use existing computer software,
existing treatment programs and procedures, existing quality standards, existing
quality assessment methods, existing performance improvement and monitoring
programs, advertising and marketing assistance, promotional materials,
consultation and other matters relating to the operation of Hospital/RTC Based
Behavioral Healthcare Businesses. All developments or additions to the "CHARTER"
System also will be automatically provided to the franchisee without the
franchisee paying any additional Franchise Fees (except to the extent that the
development or addition results in an increase in Franchise Fees due to the
Gross Revenues component of the Franchise Fees). With certain exceptions
franchisees will have the option to utilize new products and services developed
by the Company for the delivery of behavioral healthcare and Behavioral
Modification Programs and Related Services, without paying any additional
Franchise Fees (except to the extent such new products and services result in an
increase in Franchise Fees due to the Gross Revenues component of the Franchise
Fees). Each facility will operate only under the name agreed by the Company and
CBHS set forth in each Subsidiary Franchise Agreement, which will include the
name "Charter" and an indication of location only.
 
    RIGHTS GRANTED.  The rights granted under each Subsidiary Franchise
Agreement will relate solely to the Territory. The rights will be non-exclusive
except that the Company may not grant a franchise for, or itself operate, a
facility located within the Territory using the "CHARTER" System. The Company,
however, reserves the right to grant franchises or licenses to individual
physicians, psychologists or other mental healthcare professionals, or groups
thereof or entities employing such, to operate businesses for the delivery of
behavioral healthcare utilizing the "CHARTER" System at facilities in the
Territory other than at an in-patient facility. The Company reserves the right
to grant franchises to others to operate behavioral healthcare businesses
utilizing the "CHARTER" System other than in the Territory and to otherwise use
and grant to others the right to use the "CHARTER" name or any other name for
other businesses. In addition, the Company reserves the right to (i) provide
behavioral healthcare services incidental to the managed behavioral healthcare
business or any other business the principal purpose of which is not the
operation of a Hospital/RTC Based Behavioral Healthcare Business; and (ii)
pursuant to contracts with federal, state and local governments and governmental
agencies, provide health and human services, including behavioral healthcare
services, to the mentally retarded, the developmentally disabled, the elderly,
persons under the control or supervision of criminal/juvenile justice systems
and other designated populations.
 
    TERM AND RENEWAL.  Each Subsidiary Franchise Agreement will have the same
term as the Master Franchise Agreement.
 
    FRANCHISE ASSISTANCE.  During the term of each Subsidiary Franchise
Agreement, the Company will provide franchisees with the following assistance:
(i) advertising and marketing assistance including consultation, access to media
buying programs and access to broadcast and other advertising materials produced
by the Company from time to time for franchisees; (ii) risk management services,
including risk financial planning, loss control and claims management; (iii)
outcomes monitoring; (iv) national and regional contracting services; and (v)
consultation by telephone or at the Company's offices with respect to matters
relating to the franchisee's business in which the Company has expertise,
including reimbursement, government relations, clinical strategies, regulatory
matters, strategic planning and business development.
 
                                       61
<PAGE>
    FRANCHISE FEES.  Franchise Fees will be paid to the Company on behalf of the
franchisee by CBHS pursuant to the Master Franchise Agreement.
 
    STANDARDS OF OPERATION.  Franchisees will be required to (i) comply with the
rules, regulations, policies and standards prescribed from time to time by the
Company; (ii) comply with applicable federal, state and local laws, rules and
regulations; and (iii) maintain accreditation through the Joint Commission on
Accreditation of Healthcare Organizations.
 
    CONFIDENTIAL OPERATING MANUAL.  Franchisees will be required to conduct
business in accordance with various written materials and instructions provided
to franchisees from time to time, including compliance with all clinical and
operating protocols, policies and procedures. Franchisees will not be permitted
to make any changes in the "CHARTER" System without the consent of the Company,
which consent the Company may not unreasonably withhold.
 
    COVENANTS NOT TO COMPETE/CONFIDENTIALITY.  During the term of the Subsidiary
Franchise Agreement, franchisees will be prohibited from engaging in the
hospital-based behavioral healthcare business except under franchise from the
Company. For a period expiring on the earlier of three years after expiration or
termination of the Subsidiary Franchise Agreement or the thirty-second
anniversary of the Closing, the franchisee agrees not to engage in its exclusive
Territory in the operation of a Hospital/RTC Based Behavioral Healthcare
Business. The franchisees agree to keep confidential the confidential
information provided by the Company and not use such information other than to
operate its franchised business.
 
    ASSIGNMENT.  The Company may not assign its rights and duties except (i)
with the prior written consent of a franchisee and Crescent, which consent shall
not be unreasonably withheld, conditioned or delayed; or (ii) to an entity which
acquires substantially all of the Company's assets. A franchisee may not assign
its rights and duties except (i) with the prior written consent of the Company,
which consent shall
 
not be unreasonably withheld, conditioned or delayed, to an entity which
acquires substantially all of the franchisee's assets; or (ii) if the Facilities
Lease is terminated and if Crescent exercises its election under the Facilities
Lease to assume all of the obligations of the Franchisee.
 
    TERMINATION.  The franchisee may not terminate a Subsidiary Franchise
Agreement without the consent of the Company. Each Subsidiary Franchise
Agreement will be subject to termination by the Company for "good cause," which
includes certain acts of bankruptcy or insolvency of the franchisee; violation
of any transfer and assignment provision contained in the Master Franchise
Agreement; the franchisee's noncompliance with any law, rule or regulation
applicable to operation of its business (subject to reasonable attempts to
cure); material violations of confidentiality or nondisclosure covenants; the
franchisee's failure to perform or breach of any covenant, obligation, term,
condition, warranty or certification in the Master Franchise Agreement (subject
to reasonable cure periods); and the franchisee's failure to pay certain fees
owed to the Company under the Master Franchise Agreement within ten days. Upon
expiration or termination of a Subsidiary Franchise Agreement, the franchisee
must: (i) cease utilizing the "CHARTER" name and any other names and marks of
the Company; (ii) cease utilizing in any way the "CHARTER" System or hold itself
out as a present (or publicly, as a former) CBHS franchise owner or holder;
(iii) return to the Company all materials relating to the "CHARTER" System
including confidential operating manuals and materials; and (iv) pay all amounts
due to the Company, subject to the Subordination Agreement.
 
    INDEMNITY/INSURANCE.  Under each Subsidiary Franchise Agreement (i) the
franchisee will be required to indemnify and defend the Company from all losses
and liabilities arising directly or indirectly as a result of, or arising out of
or in connection with the operation of the franchised business, except those
directly resulting from the Company's willful misconduct or fraud; and (ii) the
Company will be required to indemnify the franchisee from all losses and
liabilities arising directly or indirectly as a result of, or arising out of, or
in connection with, the operation of the franchised business, except those
directly due to the Company's willful misconduct or fraud.
 
                                       62
<PAGE>
    The franchisee is required under the Subsidiary Franchise Agreement to
maintain minimum levels of insurance as required by the Company from time to
time, and to name the Company as an additional insured party as appropriate.
 
    DISPUTE RESOLUTION.  Disputes will be subject to resolution by arbitration
in Delaware.
 
SUBORDINATION AGREEMENT
 
    The Company, CBHS and Crescent will enter into a Subordination Agreement at
the Closing, which will provide that Franchise Fees are subordinated to base
rent, minimum escalator rent and the first $10 million of additional rent under
the Facilities Lease (including all renewals); provided, however, that to the
extent CBHS (with the consent of the Company) informs Crescent that capital
expenditures in excess of $10 million are required and Crescent funds or makes
an irrevocable commitment to fund capital expenditures in excess of $10 million,
then Franchise Fees are also subordinated to such expenditures or commitments in
excess of $10 million.
 
    Notwithstanding the foregoing, in the event that the accrued and unpaid
Franchise Fees, including interest thereon, if any, equal or exceed $15 million,
then CBHS' available cash will thereafter first be applied to base rent and
minimum escalator rent, but not to additional rent, under the Facilities Lease
(including all renewals). The remainder of CBHS' available cash will then be
applied in such order of priority as CBHS may determine, in the reasonable
discretion of its Board, to all other operating expenses of CBHS, including,
without limitation, the current and accumulated Franchise Fees, additional rent
due under the Facilities Lease and any other operating expenses; provided,
however, that to the extent CBHS (with the consent of the Company) informs
Crescent that capital expenditures are required and Crescent funds or makes an
irrevocable commitment to fund such capital expenditures, then CBHS' available
cash will first be applied to base rent, minimum escalator rent and the amount
of additional rent necessary to fund such capital expenditures; and further
provided that Crescent will have no obligation to refund any amounts paid by
CBHS as additional rent.
 
    The Company will be entitled to pursue all available remedies for breach of
the Master Franchise Agreement, except that the Company does not have the right
to take any action that could reasonably be expected to force CBHS into
bankruptcy or receivership, or similar proceedings, with respect to any dispute
that may arise among the parties with respect to payment or nonpayment of the
Franchise Fees.
 
    For existing management agreements, joint ventures and comparable
transactions for which there are no franchise arrangements with the Company, the
percentage of CBHS' gross receipts from such other management, joint venture or
other arrangements that are payable to the Company in lieu of Franchise Fees
will be subordinated to the same extent as if such amounts were Franchise Fees.
 
    Subordination in accordance with the foregoing will continue as long as any
base rent, minimum rent or additional rent is unpaid under the Facilities Lease
if such base rent, minimum rent or additional rent would have been entitled to
the benefits of the subordination provided for above.
 
WARRANT PURCHASE AGREEMENT
 
    SALE OF WARRANTS.  The Warrant Purchase Agreement provides that Crescent
will purchase the Warrants at the Closing. The aggregate purchase price for the
Warrants is included in the consideration to be paid by Crescent under the
Crescent Purchase Agreement. The Company has valued the Warrants at $25 million.
 
                                       63

</TABLE>
 
Crescent's rights with respect to the Warrants will not be contingent on or
subject to the satisfaction or completion of any obligation that Crescent may
have to CBHS, or that CBHS may have to the Company, or by any subordination of
fees otherwise payable to the Company by CBHS.
 
    The Warrants contain provisions relating to adjustments in the number of
shares covered by the Warrants and the warrant exercise price in the event of
stock splits, stock dividends, mergers, reorganizations and similar
transactions.
 
    TRANSFERABILITY.  Crescent agrees that it will not (i) sell or transfer any
of the Warrants to any other person, except as otherwise permitted under the
Warrant Purchase Agreement or to a wholly owned subsidiary of Crescent and (ii)
except as provided in the following paragraph, prior to the twelfth anniversary
date of the closing of the purchase of the Warrants, sell or transfer in a
privately negotiated transaction to a single purchaser and its affiliates or any
group (as defined in Rule 13d-5(b)(1) of the Exchange Act) any combinations of
Warrants and/or Warrant Shares, if the aggregate number of Warrant Shares and
shares subject to the Warrants to be so transferred equals 5% or more of the
Common Stock then outstanding on a fully-diluted basis (I.E., including all
shares of Common Stock issuable under the terms of any options, warrants and
similar rights).
 
    The Warrant Purchase Agreement provides that, notwithstanding the foregoing
paragraph, Crescent may sell or transfer any of the Warrants and/or Warrant
Shares to any person pursuant to, as a result of, or in connection with (i) a
tender offer or an exchange offer approved by the Board; (ii) the consummation
of a merger (provided the Company is not the surviving corporation in such
merger), consolidation, or sale of all or substantially all of the assets of the
Company or (iii) any other "fundamental change transaction" specified in the
Warrants. Crescent may also transfer the Warrants to COI if necessary to avoid
jeopardizing CEI's qualification as a real estate investment trust for federal
income tax purposes; provided, however, that in the event of any transfer for
such purpose, Crescent provides the Company with a written opinion of counsel to
such effect. No transfer may be made unless the purported transferee executes an
instrument acknowledging that it is bound by the foregoing transfer restriction,
and such instrument is delivered to the Company.
 
    REGISTRATION RIGHTS.  At least 90 days prior to the first date on which
Warrant Shares are issuable upon exercise of warrants, the Company agrees in the
Warrant Purchase Agreement to file with the SEC a registration statement under
the Securities Act of 1933, as amended with respect to the issuance of
 
                                       64
<PAGE>
Warrant Shares upon exercise of the Warrants and the resale of the Warrant
Shares and any Common Stock or other Equity Securities issued with respect
thereto by way of stock dividend or stock split or in connection with a
recapitalization or reorganization or otherwise. The Company also agrees to keep
such registration statement effective on a continual basis so long as Crescent
owns Warrants pursuant to which Common Shares may be purchased upon exercise
thereof, provided that the Company is not required to maintain the effectiveness
of any registration statement for more than 12 years and 60 days after the
Closing. Crescent is also given the right to have Warrant Shares included in
certain other registration statements filed by the Company under the Securities
Act of 1933.
 
    STANDSTILL.  Crescent agrees in the Warrant Purchase Agreement that during
the four-year period following the Closing it will not, and will cause its
affiliates and employees (other than the individuals specifically excepted in
the Warrant Purchase Agreement) not to, purchase additional shares of Common
Stock which would result in Crescent and its affiliates and employees owning 20%
or more of the Common Stock then outstanding; provided that Crescent and its
affiliates and employees will not be deemed to own 20% or more of the Common
Stock then outstanding solely by reason of the Company's purchase of Warrant
Shares unless they thereafter purchase additional shares of Common Stock
otherwise than pursuant to the exercise of the Warrants.
 
    REPRESENTATIONS AND WARRANTIES.  In the Warrant Purchase Agreement, the
Company makes several representations and warranties to Crescent including,
among others, representations as to (i) the Company's organization and
capitalization; (ii) the authority of the Company to execute, deliver and
perform the Warrant Purchase Agreement; (iii) noncontravention with its
Certificate of Incorporation, By-laws and other agreements; (iv) absence of
required governmental approvals; (v) the authorization of Warrant Shares; and
(vi) accuracy and completeness of filings with the SEC.
 
    CONDITIONS.  The respective obligations of Crescent and the Company to
consummate the sale of the Warrants pursuant to the Warrant Purchase Agreement
is subject to several conditions, including, among others, the truth of
representations and warranties, the performance of covenants to be performed on
or prior to the closing; absence of litigation affecting the Warrant Purchase
Agreement; and the satisfaction of all conditions to closing in the other
Transactional Documents.
 
    INDEMNIFICATION.  The Company and Crescent each agree to indemnify the other
against losses, liabilities, costs and expenses resulting from the indemnitor's
breach of representations, warranties and covenants contained in the Warrant
Purchase Agreement or in any instrument delivered pursuant thereto.
 
COI WARRANT PURCHASE AGREEMENT
 
    SALE OF WARRANTS.  The COI Warrant Purchase Agreement provides that Magellan
will purchase the COI Warrants at the Closing for an aggregate purchase price of
$10.00.
 
    TERMS OF THE WARRANTS.  Magellan will have the right to purchase up to 2.5%
of the common stock of COI outstanding at the Closing. The number of shares of
COI common stock underlying the COI Warrants will be determined as of the
Closing, and the exercise price of the COI Warrants will be based upon a
valuation of COI to be conducted by a mutually agreed upon independent appraiser
once a trading market for COI common stock has been established. The number of
shares underlying, and exercise price of, the COI Warrants will be subject to
adjustment pursuant to antidilution provisions.
 
    Notwithstanding the foregoing, (i) the Company may not exercise a particular
numbered COI Warrant until either COI or Crescent exercises its corresponding
numbered warrant under the Warrants and (ii) the number of shares of COI common
stock issuable upon exercise of each COI Warrant will be limited to the number
of shares of COI common stock that bears the same relationship to the number of
shares of COI common stock listed above for each COI Warrant as the number of
shares of Common Stock issued to Crescent and COI pursuant to the Warrants, in
connection with the corresponding numbered warrants, bears to the number of
shares of Common Stock issuable pursuant to the Warrants. The Company's rights
 
                                       65
<PAGE>
with respect to the COI Warrants will not be contingent on or subject to the
satisfaction or completion of any obligation that Magellan may have to CBHS, or
that CBHS may have to Crescent, or by any subordination of fees otherwise
payable to the Company by CBHS.
 
    The COI Warrants contain provisions relating to adjustments in the number of
shares of COI common stock covered by the COI Warrants and the warrant exercise
price in the event of stock splits, stock dividends, mergers, reorganizations
and similar transactions.
 
    TRANSFERABILITY.  The Company agrees that it will not (i) sell or transfer
any of the COI Warrants to any other person, except as otherwise permitted under
the COI Warrant Purchase Agreement or to a wholly owned subsidiary of the
Company and (ii) prior to the twelfth anniversary date of the Closing, sell or
transfer in a privately negotiated transaction to a single purchaser and its
affiliates or any group (as defined in Rule 13d-5(b)(1) of the Exchange Act) any
combinations of COI Warrants and/or COI Warrant Shares, if the aggregate number
of COI Warrant Shares and shares subject to the COI Warrants to be so
transferred equals 5% or more of the common stock then outstanding on a
fully-diluted basis (I.E., including all shares of common stock issuable under
the terms of any options, warrants and similar rights).
 
    The COI Warrant Purchase Agreement provides that the Company may sell or
transfer any of the COI Warrants and/or COI Warrant Shares to any person
pursuant to, as a result of, or in connection with (i) a tender offer or an
exchange offer approved by the board of directors of COI; (ii) the consummation
of a merger (provided COI is not the surviving corporation in such merger),
consolidation, or sale of all or substantially all of the assets of COI or (iii)
any other "fundamental change transaction" specified in the COI Warrants. No
transfer may be made unless the purported transferee executes an instrument
acknowledging that it is bound by the foregoing transfer restriction, and such
instrument is delivered to the Company.
 
    REGISTRATION RIGHTS.  Prior to the first date on which COI or Crescent first
exercises its rights to acquire Warrant Shares under the Warrant Purchase
Agreement, COI will use its best efforts to obtain effectiveness of a
registration statement under the Securities Act with respect to the issuance and
resale of the COI Warrant Shares and any common stock or other equity securities
of COI issued with respect thereto by way of stock dividend or stock split or in
connection with a recapitalization or reorganization or otherwise. COI also
agrees to keep such registration statement effective on a continual basis as
long as the Company owns COI Warrants pursuant to which COI Warrant Shares may
be purchased upon exercise thereof, provided that COI is not required to
maintain the effectiveness of any registration statement for more than 12 years
and 90 days after the Closing.
 
    STANDSTILL.  The Company agrees that during the four-year period following
the Closing, it will not, and will cause its affiliates and employees not to,
purchase additional shares of COI common stock that would result in the Company
and its affiliates and employees owning 20% or more of the COI common stock then
outstanding; provided that the Company and its affiliates and employees will not
be deemed to own 20% or more of the COI common stock then outstanding solely by
reason of the Company's purchase of COI Warrant Shares unless they thereafter
purchase additional shares of COI common stock otherwise than pursuant to the
exercise of the COI Warrants. The Company also agrees that during the 12-year
period following the Closing, it will not, and it will cause its affiliates and
employees not to, without prior COI consent, (i) effect or cause to be effected
any solicitation of proxies with respect to COI or take any action resulting in
the Company becoming a participant in any election contest with respect to COI,
or any tender or exchange offer or offer for a consolidation share exchange or
business combination involving COI or substantially all of COI's assets, (ii)
propose any matter for submission to a vote of the stockholders of COI, or (iii)
sell short any shares of COI common stock or other equity securities of COI.
 
    REPRESENTATIONS AND WARRANTIES.  The Company makes several representations
and warranties to COI including, among others, representations as to (i) the
Company's organization; (ii) the authority of the Company to execute, deliver
and perform the COI Warrant Purchase Agreement; (iii) noncontravention
 
                                       66
<PAGE>
with its Certificate of Incorporation, By-laws and other agreements; (iv)
absence of required governmental approvals; (v) the Company's investment intent
in purchasing the COI Warrants; and (vi) the Company's beneficial ownership of
COI common stock.
 
    CONDITIONS.  The respective obligations of COI and the Company to consummate
the sale of the COI Warrants pursuant to the COI Warrant Purchase Agreement is
subject to several conditions, including the truth of representations and
warranties made in the COI Warrant Purchase Agreement, the performance of
covenants to be performed on or prior to the Closing; the absence of litigation
affecting the COI Warrant Purchase Agreement; and the satisfaction of all
conditions to closing in the other Crescent Transaction Documents.
 
    INDEMNIFICATION.  The Company and Crescent each agree to indemnify the other
against losses, liabilities, costs and expenses resulting from the indemnitor's
breach of representations, warranties and covenants contained in the Warrant
Purchase Agreement or in any instrument delivered pursuant thereto.
 
FACILITIES LEASE
 
    GENERAL.  At the Closing, Crescent and CBHS (and its subsidiaries) will
enter into the Facilities Lease, which will be a triple-net lease structured as
an operating lease under which all of the Purchased Facilities will be leased by
Crescent to CBHS (and its subsidiaries).
 
    TERM.  The initial term of the Facilities Lease will be twelve years with
four renewal terms of five years each. CBHS may renew the lease as to all but
not less than all of the Facilities at its option upon notice at least one year
prior to end of the initial term or any renewal term.
 
    RENT.  The base rent for the first year of the initial term will be $40
million plus ten percent of any increase in the purchase price for the Purchased
Facilities resulting from the acquisition of additional facilities by the
Company after the execution of the Crescent Purchase Agreement and prior to the
Closing. Such rent will increase by five percent compounded annually. At the
commencement of any renewal term of the Facilities Lease, a new fair market rent
for the renewal term will be determined by agreement of the parties, or if the
parties are unable to agree on a fair market rent, then by an appraisal
mechanism. Following appraisal, Crescent will have the right to render void the
exercise of the option to extend the Facilities Lease if Crescent is not
satisfied with the fair market value rent as determined by the appraiser.
 
    CBHS will be required by the Facilities Lease to pay Crescent in each lease
year (including renewals), additional rent in the amount of $20.0 million, at
least $10.0 million of which must be used for capital expenditures each year, in
the manner and at the time directed by CBHS. CBHS will have the right, in each
lease year, to require the use of up to $10.0 million of such additional rent to
pay property taxes, insurance premiums and Franchise Fees. CBHS' failure to pay
additional rent under the Facilities Lease will not cause a default thereunder
except to the extent Crescent has made capital expenditures or advanced sums to
pay taxes, insurance premiums, assessments or Franchise Fees that have not been
reimbursed by additional rent paid by CBHS to Crescent.
 
    FINANCING OF ADDITIONS.  Crescent will have a right of first refusal in the
Facilities Lease to provide construction financing in excess of $1.0 million for
any expansion of Purchased Facilities that CBHS or its subsidiaries decides to
undertake and to provide acquisition or other permanent financing for any
additional facilities that CBHS or its subsidiaries decides to acquire. Such
financing must be on the same or better terms than those offered to CBHS or its
subsidiaries pursuant to a commitment from a third party.
 
    COVENANTS.  The Facilities Lease contains covenants on the part of CBHS,
including covenants to maintain its existence, keep true and complete records
and books of account, not make any payments of Franchise Fees except in
accordance with the Subordination Agreement, not enter into any management
agreement with respect to all or substantially all of a Purchased Facility
unless such management agreement has been approved by Crescent, keep the
Purchase Facilities free of liens, comply with laws,
 
                                       67
<PAGE>
maintain insurance on the Purchased Facilities with certain rights to self
insure, maintain the Purchased Facilities, and operate healthcare or
healthcare-related businesses in the Purchased Facilities.
 
    DEFAULTS.  Defaults under the Facilities Lease that may result in
termination thereof include (i) a failure to make required rental payments that
continues for 10 days; (ii) a failure to maintain insurance within five days
after Crescent gives notice of such lapse of insurance; (iii) a default in
performance of other covenants that continues for 30 days (subject to extension
for reasonable efforts to cure); (iv) an acceleration of any obligation of CBHS
in a principal amount in excess of $10 million for money borrowed or for the
deferred purchase price of any material property or services; (v) the occurrence
of a final, unappealable revocation of any license, permit or similar right
required for the lawful operation of any of the Purchased Facilities in
circumstances under which CBHS is required to cease its operations of a
Purchased Facility, provided, however, that if CBHS ceases its operation of such
Purchased Facility in accordance with its right to do so under the Facilities
Lease, the closing of such Purchased Facility will no longer be deemed to be a
default; (vi) certain acts of bankruptcy or insolvency; (vi) material
attachments to any of the Purchased Facilities; and (vii) a change of control of
CBHS.
 
    SUBSTITUTION AND CLOSURE OF PURCHASED FACILITIES.  CBHS will have the right
under certain conditions to substitute comparable facilities for any Purchased
Facilities it designates if the substitution has no material adverse tax
consequences to Crescent and the Franchise Agreement is transferred to the
substituted Facility. CBHS is required to pay all costs and expenses incurred in
connection with any substitution. CBHS also has the right to close facilities if
it is not in default under the Facilities Lease provided that it continues to
pay all rent due under the Facilities Lease.
 
    PLEDGE OF LEASEHOLD INTEREST.  CBHS will have the right to pledge its
leasehold interest to secure senior indebtedness provided that such pledge is
subordinate to any lien placed on the Purchased Facilities by Crescent to secure
financing for Crescent.
 
    SUBLEASING AND ASSIGNMENT.  CBHS will have the right to sublease all or any
of the Purchased Facilities, or to assign the Facilities Lease, to any affiliate
of CBHS or joint venture in which it owns at least a 25% interest provided that
CBHS remains liable for all obligations under the Facilities Lease and the
Franchise Agreement is assigned to the sublessee or assignee.
 
    REVERSION.  At the termination of the Facilities Lease, any improvements to
real estate revert to Crescent. CBHS will agree that upon expiration of the
Facilities Lease, supplies and inventory that are the equivalent in aggregate
amount in value to that reasonably established for use by the Facilities in the
immediately preceding lease year, will remain at the leased premises.
 
GOVERNMENTAL AND REGULATORY APPROVALS
 
    Under applicable law, the Company, Crescent and CBHS, may be required to
give notification to various state and federal governmental entities of the
Crescent Transactions and apply for new licenses and permits. The Company
believes that it and/or Crescent will be able to obtain any such licenses upon
application therefor in the ordinary course of business.
 
TRADING RANGE OF COMMON STOCK
 
    On January 29, 1997, the date preceding public announcement of the Crescent
Transactions, the high and low sales prices for the Common Stock on the New York
Stock Exchange were $23.625 and $23.125, respectively.
 
GENERAL ANTITRUST MATTERS
 
    Because CBHS is structured as a limited liability company, initially owned
equally by the Company and COI, the Company will not be able to exert control
over CBHS. Because CBHS will be an
 
                                       68
<PAGE>
independent company, it is possible that certain provisions of the agreements
between the Company and CBHS could be challenged by others as adversely
affecting their ability to compete with CBHS or the Company and therefore as
agreements in restraint of trade in violation of state or federal antitrust
laws. Such a challenge would not have been possible with respect to the
Company's operation of the Facilities through its wholly-owned Charter
subsidiary.
 
    The Company may in the future license the right to use the "CHARTER" name,
protocols and other intellectual property to companies other than CBHS. It is
frequently the case that disputes between a franchisor and its franchisee(s)
involve issues relating to actual or potential competition between them. Such
disputes may give rise to a claim that the franchisor's conduct has violated the
antitrust laws. Thus, the Company's decision to create CBHS and to engage in
franchising operations involving CBHS and others will increase its exposure to a
claim that it has violated state or federal antitrust laws. The Company does not
believe that any of the proposed transactions will have an adverse effect on
competition. The Company intends and attempts to conduct its affairs in strict
compliance with the antitrust laws.
 
SELECTED FINANCIAL DATA
 
    The following tables set forth selected historical and pro forma financial
information of the Company for each of the five fiscal years in the period ended
September 30, 1996 and for the three months ended December 31, 1995 and 1996.
The information prior to August 1992 is not comparable because of the
consummation of the Plan and the implementation of fresh start accounting in
fiscal 1992, which included the revaluation of the Company's assets and
liabilities and resulted in, among other things, significant reductions in
long-term debt and interest expense and elimination of preferred stock and
preferred stock dividend requirements. In 1993, the Company restated its
consolidated financial statements to reflect the sale of certain subsidiaries as
discontinued operations. The Historical Summary of Operations and Balance Sheet
Data for the five fiscal years in the period ended September 30, 1996, presented
below, has been derived from, and should be read in conjunction with "Item 1.
Business", "Item 7. Management's Discussion and Analysis of Financial Condition
and Results of Operations" and the Consolidated Financial Statements of the
Company included in the Company's Annual Report on Form 10-K, as amended, for
the fiscal year ended September 30, 1996, which is incorporated herein by
reference. The Historical Summary of Operations for the three months ended
December 31, 1995 and 1996 and Balance Sheet Data as of December 31, 1996 has
been derived from and should be read in conjunction with the Condensed
Consolidated Financial Statements and Management's Discussion and Analysis of
Financial Condition and Results of Operations of the Company included in the
Company's Quarterly Report on Form 10-Q for the quarterly period ended December
31, 1996, which is incorporated herein by reference.
 
    The Unaudited Pro Forma Consolidated Financial Statements are presented
using two different assumptions. Under the terms of the Indenture, Noteholders
may elect to have the Company repurchase their Notes at 101% of the face value
of the Notes after the Closing. The first presentation assumes that no
Noteholders elect to have their Notes repurchased, with the net proceeds from
the Crescent Transactions, after payment of indebtedness outstanding under the
Revolving Credit Agreement and other long-term debt, held on deposit with no
investment return. If the excess proceeds from the Crescent Transactions were
assumed to be invested at Magellan's historic temporary cash investment rate of
5.4% for the year ended September 30, 1996 and 5.25% for the three months ended
December 31, 1996, pro forma consolidated net income and net income per common
share would be $24.5 million and $0.86, respectively, for the year ended
September 30, 1996 and $9.5 million and $0.33, respectively, for the three
months ended December 31, 1996. The second presentation assumes that all
Noteholders elect to have their Notes repurchased by the Company and no net
proceeds from the Crescent Transactions available for deposit. On January 29,
1997, the date preceding public announcement of the Crescent Transactions, the
bid and asked prices of the Notes on the New York Stock Exchange were 110.75%
and 111.25% of the face value of the Notes, respectively. On April 17, 1997, the
bid and asked prices of the Notes on the New York Stock Exchange were 107% and
112% of the face value of the Notes, respectively.
 
    The Pro Forma Summary of Operations for the fiscal year ended as of
September 30, 1996 and the three months ended December 31, 1996, and the Pro
Forma Balance Sheet Data as of December 31, 1996 have been derived from, and
should be read in conjunction with, the Unaudited Pro Forma Consolidated
Financial Information, which is included elsewhere in this Proxy Statement and
is incorporated herein by reference.

UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION
 
    The Unaudited Pro Forma Consolidated Financial Statements are based on the
historical presentation of the consolidated financial statements of Magellan and
the historical operating results and financial position of the proposed divested
operations and assets. The Unaudited Pro Forma Consolidated Statements of
Operations for the year ended September 30, 1996 and the three months ended
December 31, 1996 give effect to the Crescent Transactions as if they had
occurred on October 1, 1995. The Unaudited Pro Forma Consolidated Statement of
Operations for the year ended September 30, 1996 also gives effect to the
European Sale and the following transactions completed during fiscal 1996 as if
such transactions had been completed on October 1, 1995: (i) the Green Spring
Acquisition, (ii) the issuance of the Shares, (iii) the Share Repurchase and
(iv) the pre-closure operating results for the nine acute care psychiatric
hospitals that were closed or sold during fiscal 1996. The Company acquired a
61% ownership interest in Green Spring in December 1995. The Shares represent
the 4,000,000 shares issued to Rainwater-Magellan on January 25, 1996. The Share
Repurchase represents the Company's repurchase of approximately 3,962,000 shares
of Common Stock on September 27, 1996. The unaudited Pro Forma Consolidated
Statements of Operations for the three months ended December 31, 1996 also gives
effect to the European Sale as if such transaction occurred on October 1, 1995.
The Unaudited Pro Forma Consolidated Balance Sheet as of December 31, 1996 gives
effect to the Crescent Transactions and European Sale as if they had occurred on
December 31, 1996.
 
    The Crescent Transactions will result in (i) the sale of substantially all
of the Company's domestic provider real estate and related equipment for $400
million (before costs estimated at $12.5 million) and the COI warrants to
acquire 2.5% of the outstanding common stock of COI, (ii) the creation of CBHS,
which will become a 50% owned subsidiary of the Company engaged in the
behavioral healthcare provider business and (iii) the Company's entry into the
healthcare franchising business. CBHS will lease the Purchased Facilities from
Crescent under a twelve-year operating lease (subject to renewal) for $40
million annually with a 5% escalator, compounded annually. Magellan will issue
2,566,622 warrants to Crescent and COI (1,283,311 Warrants each) with an
exercise price of $30 per share. The Warrants issued to Crescent and COI have
been valued at $25 million in the Pro Forma Balance Sheet. The exercise price of
the COI Warrants was not determinable at the date of mailing the proxy materials
as COI is in the process of formation and does not have an established stock
price. Accordingly, the COI Warrants have been ascribed no value in the Pro
Forma Balance Sheet. The valuation of the COI Warrants will not be determinable
until the exercise price is determined and, The Company anticipates that the COI
Warrants will be ascribed nominal or no value. The Company will account for its
50% investment in CBHS under the equity method of accounting, which will
significantly reduce the revenues and related operating expenses presented in
the Company's Statement of Operations. Divested Operations in the Pro Forma
Statements of Operations represents the businesses that will be operated by CBHS
after the closing. CBHS will include a significant portion of the business
included in Magellan's provider business segment and a portion of Magellan
corporate overhead. A summary of Magellan's provider business operations for the
year ended September 30, 1996 is as follows (000's):

    The Company expects to incur a loss before income taxes, minority interest
and extraordinary items of approximately $57 million upon consummation of the
Crescent Transactions. The components of the loss from the Crescent Transactions
are more fully described in Note 25 to the Pro Forma Consolidated Financial
Statements.
 
    The Unaudited Pro Forma Consolidated Financial Statements are presented
using two different assumptions. Under the terms of the Indenture, Noteholders
may elect to have the Company repurchase their Notes at 101% of the face value
of the Notes after the Closing. The Company will mail a notice to the
Noteholders within 10 days after the Closing which will, among other things,
state the latest date which the holders of the Notes will have to tender their
Notes to the Company (the "Notes Payment Date"). The Notes Payment Date cannot
be less than 30 days nor more than 60 days from the date such notice is mailed.
On the Notes Payment Date, the Company will be required to provide sufficient
funds to the Trustee to redeem all tendered Notes plus accrued interest to the
Notes Payment Date. The Company will not hire any outside agents to assist in
this process. Noteholder consent or approval of the Crescent Transactions is not
required. Noteholders may elect to have the Company repurchase their Notes for
various reasons including, but not limited to, concerns about the Company's
prospects after the Crescent Transactions, liquidity of the Notes in the open
market and prevailing bond and equity market conditions at the Notes Payment
Date.
 
    The first presentation assumes that no Noteholders elect to have their Notes
repurchased and the net proceeds from the Crescent Transactions are deposited
with no investment return after payment of indebtedness outstanding under the
Revolving Credit Agreement and industrial revenue bonds for certain of the
Purchased Facilities. If the excess proceeds from the Crescent Transactions were
assumed to be invested at Magellan's historic temporary cash investment rate of
5.4% for the year ended September 30, 1996 and 5.25% for the three months ended
December 31, 1996, pro forma consolidated net income and net income per common
share would be $24.5 million and $0.86, respectively, for the year ended
September 30, 1996 and $9.5 million and $0.33, respectively, for the three
months ended December 31, 1996.
 
    The second presentation assumes that all Noteholders elect to have their
Notes repurchased by the Company and no net proceeds from the Crescent
Transactions are available for deposit. On January 29, 1997, the date preceding
public announcement of the Crescent Transactions, the bid and asked prices of
the Notes on the New York Stock Exchange were 110.75% and 111.25% of the face
value of the Notes, respectively. On April 17, 1997, the bid and asked prices of
the Notes on the New York Stock Exchange were 107% and 112% of the face value of
the Notes, respectively.
 
    The Unaudited Pro Forma Consolidated Financial Statements do not purport to
be indicative of the results that actually would have been obtained if the
operations had been conducted as presented and they are not necessarily
indicative of operating results to be expected in future periods. The Company's
hospital business is seasonal in nature with a reduced demand for certain
services generally occurring in the first fiscal quarter around major holidays,
such as Thanksgiving and Christmas, and during the summer months comprising the
fourth fiscal quarter. The Franchise Fees are recognized ratably throughout the
year for purposes of the Unaudited Pro Forma Consolidated Financial Statements.
Accordingly, the Unaudited Pro Forma Statement of Operations for the three
months ended December 31, 1996 are not necessarily indicative of the pro forma
results expected for a full year. The Unaudited Pro Forma Consolidated Financial
Statements and notes thereto should be read in conjunction with the historical
consolidated financial statements and notes thereto of Magellan, which are
incorporated herein by reference.

              NOTES TO PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS
    Notes (1) through (5) relate to the effect of the Green Spring Acquisition,
the issuance of the Shares, the Share Repurchase and the European Sale as if
such transactions occurred on October 1, 1995.
 
 (1) The pro forma adjustments to amortization expense represent an increase to
    amortization expense in conjunction with the 61% acquisition of Green
    Spring.
 
 (2) The pro forma adjustments to interest expense, net, represent the interest
    expense incurred and the interest income foregone by Magellan as a result of
    the Green Spring Acquisition and the Share Repurchase, net of reductions in
    interest expense as a result of the issuance of the Shares and the European
    Sale. Historic interest rates used for borrowings and temporary cash
    investments were approximately 7.6% and 5.4%, respectively.
 
 (3) The pro forma adjustments to income taxes represent the tax effect of the
    pro forma adjustment to interest expense at Magellan's historic effective
    tax rate of 40%.
 
 (4) The pro forma adjustments to minority interest represent the 39% minority
    interest in Green Spring and GPA as a result of the Green Spring
    Acquisition.
 
 (5) The pro forma adjustments to average number of common shares outstanding
    give effect to the issuance of shares in the Green Spring Acquisition and
    the issuance of the Shares, offset by the Share Repurchase.
 
 (6) The pro forma adjustments to net revenue represent Franchise Fees paid to
    Magellan by CBHS pursuant to the Master Franchise Agreement. As part of the
    Crescent Transactions, CBHS will lease the Purchased Facilities from
    Crescent under the Facilities Lease. See "Crescent Transactions-- Facilities
    Lease." The annual base rent under the Facilities Lease begins at $40
    million and escalates 5% per year, compounded annually. The Subordination
    Agreement provides that the Franchise Fees are subordinated in payment to
    the $40 million annual base rent, 5% escalator rent and the additional rent
    under the Facilities Lease due Crescent, in certain circumstances. (See
    "Crescent Transactions-- Subordination Agreement"). The Company will be
    entitled to pursue all available remedies for breach of the Master Franchise
    Agreement, except that the Company does not have the right to take any
    action that could reasonably be expected to force CBHS into bankruptcy or
    receivorship. If CBHS encounters a decline in earnings or financial
    difficulties, such amounts due Crescent will be paid before any Franchise
    Fees are paid. After the Crescent Transactions, the Company will receive
    from CBHS initial Franchise Fees of $81 million, subject to increase (See
    "Crescent Transactions--Master Franchise Agreement"). The Company will
    provide CBHS with an array of services, including advertising and marketing
    assistance, risk management services, outcomes monitoring, consultation with
    respect to matters relating to CBHS' business in which the Company has
    expertise and the Company's operation of a telephone call center utilizing
    the "1-800-CHARTER" telephone number.
 
 (7) The pro forma adjustments to salaries, supplies and other operating
    expenses represent fees payable to CBHS of $10.6 million and $1.6 million
    for the year ended September 30, 1996 and the three months ended December
    31, 1996, respectively, for the management of hospital-based businesses
    controlled by Magellan that are less than wholly-owned by Magellan, net of
    reductions in corporate overhead of $7.2 million and $1.5 million for the
    year ended September 30, 1996 and the three months ended December 31, 1996,
    respectively, related to the transfer of existing personnel and functions
    between Magellan and CBHS. The Company and CBHS expect to incur incremental
    corporate overhead of approximately $1 million annually as a result of the
    Crescent Transactions. Magellan personnel transferred to CBHS and
    incremental corporate overhead will occur primarily in the human resource,
    legal and finance and accounting functions.
 
 (8) The pro forma adjustments to depreciation and amortization represent the
    amortization expense related to other intangible assets that would become
    impaired as a result of the Crescent Transactions.

    The impaired other intangible assets have a remaining net book value of
    approximately $170,000 at December 31, 1996, which are included in the
    impairment losses referred to in Note (17).
 
 (9) The pro forma adjustments to interest expense, net, assuming all of the
    Notes are repurchased, represents the reduction in interest expense for the
    assumed repurchase of the Notes at 101% of the aggregate principal amount
    pursuant to the provisions of the Indenture, offset by additional borrowings
    under the new credit agreement required to fund the assumed repurchase of
    the Notes. The pro forma adjustment to interest expense, net, assuming the
    Notes are not repurchased, represents reductions in interest expense as a
    result of paying off the outstanding borrowings under the Revolving Credit
    Agreement (historic and pro forma) with no assumed investment of the excess
    proceeds from the Crescent Transactions. If the excess proceeds from the
    Crescent Transactions were assumed to be invested at Magellan's historic
    temporary cash investment rate of 5.4% for the year ended September 30, 1996
    and 5.25% for the three months ended December 31, 1996, pro forma
    consolidated net income and net income per common share would be $24.5
    million and $0.86, respectively, for the year ended September 30, 1996 and
    $9.5 million and $0.33, respectively, for the three months ended December
    31, 1996.
 
(10) The pro forma adjustments to equity in loss of CBHS represent Magellan's
    percentage interest (50%) in CBHS' pro forma loss for the year ended
    September 30, 1996 and the three months ended December 31, 1996. Magellan's
    investment in CBHS will be accounted for under the equity method of
    accounting. The timing and terms of the 10% equity interest grant to CBHS
    management will be addressed by the governing board of CBHS after the
    Closing. The Company anticipates that the granting of the 10% equity
    interest to CBHS management will result in equally shared dilution of
    ownership interest between Magellan and COI and that the grant will be at an
    exercise price at least equal to the fair value of the underlying equity at
    the date of grant, which will not result in compensation expense under the
    provisions of APB Opinion 25. Magellan's ownership interest in CBHS is
    reflected at its initial ownership percentage of 50% for the purposes of
    computing pro forma equity in loss of CBHS. The Condensed Pro Forma
    Statements of Operations and Balance Sheet of CBHS are as follows (000's):

(16) The pro forma adjustments to Investment in/Advances to CBHS represent
    Magellan's capital contribution for its 50% ownership and voting interest in
    CBHS in the form of contributed net assets and advances to CBHS for working
    capital purposes. Magellan will either (i) provide CBHS with bridge
    financing, secured by CBHS' receivables, for a one-year term in the maximum
    amount of $55 million to fund CBHS' anticipated working capital needs during
    its first year of operation or (ii) provide a guarantee under certain
    circumstances, not to exceed $65 million, for a CBHS bank line of credit
    secured by CBHS' receivables. CBHS has received a loan commitment from a
    group of commercial banks to provide a line of credit of up to $100 million
    pursuant to a 5-year revolving credit facility.

    Each of the Company and COI will make a commitment to loan CBHS up to $17.5
    million each, for a period of five years. The Company will have the right to
    require CBHS to draw down a portion of its loan commitment, which will be
    funded equally by the Company and COI, and will be used in the manner
    directed by the Company. The fair value of the net assets contributed to
    CBHS by Magellan is approximately $5.5 million and the pro forma advance to
    CBHS by Magellan is approximately $10.0 million.
(17) The pro forma adjustments to goodwill and other intangible assets represent
    impairment losses related primarily to hospital-based goodwill and other
    intangible assets as a result of the Crescent Transactions, including the
    write-off of approximately $9.1 million in unamortized deferred financing
    costs if the Notes are repurchased. The Company is disposing of a
    significant portion of its provider business segment. The impairment loss
    results from reducing the book value of the Company's investment in CBHS to
    its approximate fair value. The impairment losses represent the carrying
    amount of goodwill and other intangible assets related to the divested or
    contributed operations.
(18) The pro forma adjustments to accrued liabilities represent the accrual of
    $5.0 of exit costs and the remaining obligation to construct the
    Philadelphia Purchased Facility of $10.6 million, less the payment of
    accrued interest for debt serviced as a result of the Crescent Transactions
    of $9.3 million if the Notes are repurchased and $0.4 million if the Notes
    are not repurchased, and $6.7 million of accrued vacation liabilities
    assumed by CBHS. The Company is exiting the domestic provider business as a
    result of the Crescent Transactions. See "Summary--Crescent Transactions"
    for a description of the major actions comprising the exit plan. The type
    and amount of exit costs accrued are as follows (000's):

    The Closing of the Crescent Transactions will result in accelerated vesting
    for options to purchase 1,210,375 shares of Common Stock under the 1996
    Stock Option Plan. The accelerated vesting of options under the 1996 Stock
    Option Plan is triggered by the Closing of the Crescent Transactions. The
    Company believes the Crescent Transactions meet the definition of a "sale
    ... of all or substantially all" of the Company's assets included in the
    1996 Stock Option Plan, which is supported by relevant Delaware case law.

VOTE REQUIRED
 
    Approval and adoption of the Crescent Transactions by stockholders requires
the affirmative vote at the Annual Meeting of a majority of the outstanding
shares of Common Stock. Assuming the existence of a quorum, any shares of Common
Stock not voted at the Annual Meeting, whether due to abstentions, broker
non-votes or otherwise, will have the effect of a vote against the Crescent
Transactions. Shares of Common Stock owned by the Rainwater Group will be voted
in the same percentage as the shares of Common Stock held by disinterested
stockholders. (See "The Crescent Transactions- Interested Parties.") Under this
standard, the Crescent Transactions will only be approved if the votes cast by
stockholders (other than the Rainwater Group) in favor of the Crescent
Transactions exceed the votes cast by stockholders (other than the Rainwater
Group) against the Crescent Transactions.
 
    THE BOARD HAS UNANIMOUSLY APPROVED (WITH DIRECTOR DARLA D. MOORE NOT
PARTICIPATING BECAUSE OF HER BENEFICIAL OWNERSHIP IN CRESCENT) THE CRESCENT
TRANSACTIONS AND RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" THE CRESCENT
TRANSACTIONS. SHARES OF COMMON STOCK REPRESENTED AT THE ANNUAL MEETING BY SIGNED
BUT UNMARKED PROXIES WILL BE VOTED "FOR" THE CRESCENT TRANSACTIONS.
 
CERTAIN ANTITAKEOVER PROVISIONS
 
    DELAWARE LAW.  Section 203 of the Delaware General Corporation Law generally
prohibits certain Delaware corporations from engaging in a "business
combination" with an "interested stockholder" for a period of three years after
the date of the transaction in which the person became an interested
stockholder, unless (i) prior to the date of the business combination, the
transaction is approved by the board of directors of the corporation, (ii) upon
consummation of the transaction which resulted in the stockholder becoming an
interested stockholder, the interested stockholder owns at least 85% of the
outstanding voting stock or (iii) on or after the consummation date, the
business combination is approved by the board and by the affirmative vote of at
least 66_% of the outstanding voting stock which is not owned by the interested
stockholder. "Business combinations" include mergers, asset sales and other
transactions resulting in a financial benefit to the stockholder. An "interested
stockholder" is a person who, together with affiliates and associates, acquired
15% or more of the corporation's voting stock in a transaction not approved by
the board. A Delaware corporation may "opt out" from the application of Section
203 through a provision in its certificate of incorporation or by-laws. The
Company has not "opted out" from the application of Section 203. However,
Rainwater-Magellan is not subject to Section 203 because the Private Placement
was approved by the Board.
 
    CERTAIN PROVISIONS OF THE CERTIFICATE OF INCORPORATION.  The Certificate of
Incorporation provides that the number of directors of the Company is fixed at
eight. Directors are divided into three classes, with nominees in a single class
being elected each year to serve three year terms. Three directors serve in the
class whose terms will expire in 1998, two directors serve in the class whose
terms will expire in 1999 and three directors serve in a class whose terms will
expire in 2000. The number of directors may be changed only by the affirmative
vote of at least 75% of the issued and outstanding shares of capital stock of
the Company. Any director may be removed, but only (i) for cause by the
affirmative vote of a majority of the issued and outstanding shares of capital
stock of the Company or (ii) without cause by the affirmative vote of 75% of the
issued and outstanding shares of capital stock of the Company. The Certificate
of Incorporation provides that special meetings of stockholders may be called
only by the affirmative vote of a majority of the directors. The Certificate of
Incorporation also prohibits stockholders of the Company from taking action by
written consent without a meeting of stockholders.
 
    RIGHTS PLAN.  The Company has adopted the Rights Plan, pursuant to which
each share of Common Stock has attached thereto one Right. The Rights trade
automatically with the underlying shares of Common Stock. Upon becoming
exercisable, but prior to the occurrence of certain events, each Right initially
entitles its holder to buy one share of Common Stock from the Company at an
exercise price of $60. The Rights will be distributed and become exercisable
only if a person or group acquires, or
 
                                       90
<PAGE>
announces its intention to acquire, Common Stock exceeding certain levels
specified in the Rights Plan. Upon the occurrence of such events, the exercise
price of each Right reduces to one-half of the then current market price. The
Rights also give the holder certain rights in an acquiring company's common
stock. The Company may redeem the Rights at a price of $.01 per Right at any
time prior to the distribution of the Rights. The Rights have no voting power
until exercised.
 
    The foregoing provisions could have the effect of delaying, deferring or
preventing a change in control or the removal of existing management of the
Company.
 
                   AMENDMENT TO CERTIFICATE OF INCORPORATION
 
    The information contained in this Proxy Statement with respect to the
Certificate Amendment is qualified in its entirety by reference to the text of
the proposed amendment to the Certificate of Incorporation, which is attached
hereto as Appendix II and incorporated herein by reference.
 
    If approved at the Annual Meeting, the Certificate Amendment will increase
the size of the Board from 8 to 12. The Board believes that the Certificate
Amendment is advisable because it will allow the addition of directors who will
bring additional experience and expertise to the Board.
 
    The Certificate Amendment also deletes certain provisions from the
Certificate of Incorporation that relate to the Company's emergence from
bankruptcy in 1992, which are no longer applicable.
 
VOTE REQUIRED
 
    Approval and adoption of the Certificate Amendment by stockholders requires
the approval at the Annual Meeting of 75% of the outstanding shares of Common
Stock. Assuming the existence of a quorum, any shares of Common Stock not voted
at the Annual Meeting, whether due to abstentions, broker non-votes or
otherwise, will have the effect of a vote against the Certificate Amendment.
 
    THE BOARD HAS UNANIMOUSLY APPROVED THE CERTIFICATE AMENDMENT AND RECOMMENDS
THAT STOCKHOLDERS VOTE "FOR" THE CERTIFICATE AMENDMENT. SHARES OF COMMON STOCK
REPRESENTED AT THE ANNUAL MEETING BY SIGNED BUT UNMARKED PROXIES WILL BE VOTED
"FOR" THE CERTIFICATE AMENDMENT.
 
                        PROPOSED 1997 STOCK OPTION PLAN
 
    The following summary description of the 1997 Plan is qualified in its
entirety by reference to the full text of the 1997 Plan, which is attached
hereto as Appendix III and incorporated herein by reference.
 
    On February 28, 1997, the Board adopted, subject to stockholder approval at
the Annual Meeting, the Magellan Health Services, Inc. 1997 Stock Option Plan.
The purpose of the 1997 Plan is to motivate and retain officers and other key
employees of the Company and its subsidiaries who have major responsibility for
the attainment of the primary long-term performance goals of the Company. The
1997 Plan will enable officers and eligible key employees of the Company and its
subsidiaries to acquire a proprietary interest in the Company through the
ownership of Common Stock.
 
    Under the terms of the 1997 Plan, options can be granted to participants to
purchase, out of authorized but unissued Common Stock or out of shares of Common
Stock held in the Company's treasury, or partly out of each, a total of
1,500,000 shares of Common Stock. Both the number of shares of Common Stock
covered by the 1997 Plan and the per share exercise price of options granted are
subject to adjustment upon certain changes in capitalization of the Company,
such as stock splits or stock dividends.
 
    The 1997 Plan is administered by the Compensation Committee or such
committee as may from time to time be designated by the Board to administer the
1997 Plan (the Committee). The Committee is required to be comprised of not
fewer than two members of the Board, each of whom is a "non-employee director"
as that term is defined in Rule 16b-3 under the Exchange Act. The Committee
administers the
 
                                       91
<PAGE>
1997 Plan, selects the eligible participants to whom the options will be
awarded, determines the number of shares for which options are to be awarded to
each eligible participant, and determines the terms and conditions of each
option, subject to the provisions of the 1997 Plan. The duties of the Committee
in granting options to officers and key employees may be delegated to the
Company's Chief Executive Officer with respect to any person except any person
who has been designated a "named executive officer" (as defined by SEC rules)
with respect to the Company's last completed fiscal year, subject to any review,
approval or notification required by the Committee or as may otherwise be
required by law. The Committee may from time to time prescribe, amend and
rescind such rules, regulations, provisions and procedures, consistent with the
terms of the 1997 Plan, as, in its opinion, may be advisable in the
administration of the 1997 Plan and the Committee approves the provisions of the
stock option agreements required by the 1997 Plan. Options granted under the
1997 Plan are nonqualified stock options.
 
    Any officer or employee of the Company or any of its subsidiaries who has
been selected by the Committee is eligible to participate in the 1997 Plan.
 
    Subject to the approval of the 1997 Plan by the stockholders, both the
Committee and the Chief Executive Officer have granted options under the terms
of the 1997 Plan. Each of these option grants (as indicated in the following
table) was made on February 28, 1997 at an exercise price of $24.81.

    The options listed above, and options subsequently granted, will have a per
share exercise price equal to the mean between the high and low sales prices per
share of the Common Stock on the New York Stock Exchange on the date of grant of
the options. More than one grant of an option may be made to the same person,
but no person may be granted options under the 1997 Plan to purchase in the
aggregate more than 1,000,000 shares of Common Stock. The closing price of the
Common Stock on March 31, 1997 was $24.625 per share.
 
    Options granted under the 1997 Plan will be exercisable to the extent
vested. An option vests at the rate of 33 1/3% of the shares covered by the
option on each of the first three anniversary dates of the grant of the option
if the optionee is an employee of the Company or a subsidiary of the Company on
such dates. Options granted pursuant to the 1997 Plan that are vested may be
exercised in whole or in part by the optionee from time to time, but in no event
later than February 28, 2007. All unvested options fully vest and are
immediately exercisable upon any "change of control," defined as the effective
date, at any time after March 18, 1997, of (i) the sale, lease transfer or other
disposition in one or more related transactions of all or substantially all of
the Company's assets, to any person or related group of persons (including a
"group" as such term is used in Section 13(d)(3) of the Exchange Act), (ii) the
merger or consolidation of the Company with or into another corporation, the
merger of another corporation in the Company or any other transaction, with the
effect that the stockholders of the Company immediately prior to such
transaction hold less than 50% of the total voting power or the voting stock of
the surviving corporation resulting from such consolidation or such other
transaction, (iii) any person or related group of persons holding 30% or more in
interest of the voting power or voting stock of the Company, or (iv) the
liquidation or dissolution of the Company. The 1997 Plan specifically excludes
the Crescent Transactions from the definition of "change of control." The
exercise price is payable upon the exercise of the option in cash.
 
                                       92
<PAGE>
    The 1997 Plan provides that: (i) upon termination of employment for any
reason except death or total disability, unvested options granted will terminate
on the date of termination of employment and vested options on the date of
termination may be exercised during the six months following termination (but
not after expiration of the term of the option); (ii) upon total disability of a
participant, vested options on the date the participant became totally disabled
may be exercised by the participant within 12 months from the date of total
disability of the participant (but not after expiration of the term of the
option); and (iii) upon the death of a participant, the vested options on the
date of the participant's death may be exercised by the legal representative,
heir or legatee within 12 months of the date of death of the participant (but
not after expiration of the term of the option).
 
    Options under the 1997 Plan must be granted on or before December 31, 2000.
No option granted under the 1997 Plan may be assigned or transferred by the
participant except by will or by the laws of descent and distribution.
 
    Subject to certain limitations set forth in the 1997 Plan, the Board may at
any time or from time to time terminate, modify or amend the 1997 Plan. No
amendment may be made without stockholder approval if such approval is required
for continued compliance with Rule 16b-3 of the Exchange Act, by other
applicable law or regulation or by the rules of any stock exchange on which the
Common Stock is listed for trading. The termination or any modification or
amendment of the 1997 Plan or options thereunder may not, without the consent of
the participant, affect such person's rights under an option previously granted.
 
    Under the Code and current regulations, a participant is not subject to any
federal income tax upon the grant of an option under the 1997 Plan and the grant
of an option will not result in an income tax deduction for the Company.
 
    Upon the exercise of an option, the participant will recognize ordinary
income in an amount equal to the excess of the fair market value of the shares
at the time of purchase over the exercise price. At that time the Company will
be entitled to a deduction in an amount equal to the amount taxable to the
participant as income, provided the Company satisfies applicable federal income
tax reporting requirements. The sale or other taxable disposition of shares of
Common Stock acquired upon exercise of an option generally will result in a
short or long-term capital gain or loss equal to the difference between the
amount realized on the disposition and the fair market value of the shares of
Common Stock when the option was exercised.
 
    The 765,000 options granted on February 28, 1997 at an exercise price of
$24.81 may result in compensation expense to the Company during fiscal years
1997 through 2000 if the 1997 Plan is approved. The measurement date for
purposes of measuring compensation expense will be the date of stockholder
approval. To the extent the mean between the high and low sales price per share
of the Common Stock exceeds $24.81 on the date of stockholder approval, the
Company will be required to record compensation expense for such options over
the three year vesting period.
 
VOTE REQUIRED
 
    Approval and adoption of the 1997 Plan by stockholders requires the
affirmative vote of a majority of the shares of Common Stock represented and
entitled to vote at the Annual Meeting. Assuming the existence of a quorum,
abstentions will be treated as a vote against the 1997 Plan and broker non-votes
will be disregarded and will have no effect on the outcome of the vote.
 
    THE BOARD HAS UNANIMOUSLY APPROVED THE 1997 PLAN AND RECOMMENDS THAT
STOCKHOLDERS VOTE "FOR" THE 1997 PLAN. SHARES OF COMMON STOCK REPRESENTED AT THE
ANNUAL MEETING BY SIGNED BUT UNMARKED PROXIES WILL BE VOTED "FOR" THE 1997 PLAN.

    Section 16(a) of the Exchange Act requires the Company's directors, certain
officers and persons who own more than 10% percent of the Common Stock to file

were required, the Company believes that all persons who are required to comply
with the Section 16(a) filing requirements with respect to the Common Stock have
complied with such filing requirements on a timely basis.

Ladies and Gentlemen:
 
    Magellan Health Services, Inc., a Delaware corporation ("Magellan" or the
"Company"), and Crescent Real Estate Equities Limited Partnership, a Delaware
limited partnership ("Crescent"), have entered into a Real Estate Purchase and
Sale Agreement, dated as of January 29, 1997, (the "Real Estate Purchase
Agreement"). In connection with the transactions contemplated by the Real Estate
Purchase Agreement, (i) Magellan and Crescent have entered into (x) that certain
Contribution Agreement of even date therewith (the "OpCo Contribution
Agreement") and (y) that certain Crescent Warrant Purchase Agreement of even
date therewith (the "Crescent Warrant Purchase Agreement") and (ii) Magellan has
entered into that certain Warrant Purchase Agreement (the "Opportunity Corp.
Warrant Purchase Agreement"), to be dated as of the date of the Closing (as
defined in the Real Estate Purchase Agreement), with Crescent Opportunity Corp.,
a Delaware corporation ("Opportunity Corp."). Pursuant to the Real Estate
Purchase Agreement, the OpCo Contribution Agreement, the Crescent Warrant
Purchase Agreement and the Opportunity Corp. Warrant Agreement, Magellan (1)
will cause Charter Behavioral Health Systems, Inc., a Delaware corporation and a
wholly owned subsidiary of Magellan ("Charter"), to sell to Crescent
substantially all of the real property and related improvements owned, directly
or indirectly, by Charter and used in the operation of Charter's behavioral
health care facilities (the "Purchased Facilities"); (2) will transfer, pursuant
to the OpCo Contribution Agreement, to Charter Behavioral Health Systems, LLC, a
newly-formed joint venture ("OpCo"), owned equally by Magellan and Crescent,
certain tangible personal property, including equipment, and certain intangible
rights used in connection with Charter's operation of the Purchased Facilities,
but excluding certain tangible property that Magellan will use in the provision
of certain services and certain intangible property that Magellan will license
to OpCo (such excluded property hereinafter referred to as the "Retained
Franchise Assets") pursuant to the Franchise Agreements (as defined below); (3)
will enter into (a) a master franchise agreement with OpCo (the "Master
Franchise Agreement") and (b) franchise agreements with OpCo's subsidiaries (the
"Subsidiary Franchise Agreements" and collectively with the Master Franchise
Agreement, the "Franchise Agreements") pursuant to which OpCo will (A) operate
the Purchased Facilities and other facilities operated by OpCo and (B) pay
certain franchise fees to Magellan; (4) will cause OpCo to lease the Purchased
Facilities pursuant to a Master Lease (the "Facilities Lease") between Crescent
and OpCo; (5) will enter into a Subordination Agreement (the "Subordination
Agreement") with Crescent pursuant to which Magellan's right to receive
franchise fee payments under the Franchise Agreements will be subordinated to
Crescent's right to receive rental payments under the Facilities Lease as and to
the extent provided in the Subordination Agreement; (6) will enter into an
Operating Agreement (the "Operating Agreement") governing the operation of OpCo;
(7) will issue to Crescent warrants to purchase up to 2,567,000 shares of common
stock, par value $.25 per share (the "Common Stock") of the Company
 
                              Appendix I - Page 1
<PAGE>
(the "Crescent Warrants") pursuant to the Crescent Warrant Purchase Agreement;
and (8) will purchase from Opportunity Corp. warrants to purchase that number of
shares of common stock of Opportunity Corp. representing 2.5% of the outstanding
common stock of Opportunity Corp. (the "Opportunity Corp. Warrants") pursuant to
the Opportunity Corp. Warrant Purchase Agreement. The Real Estate Purchase
Agreement, the OpCo Contribution Agreement, the Crescent Warrant Purchase
Agreement, the Opportunity Corp. Warrant Purchase Agreement, the Franchise
Agreements, the Facilities Lease, the Subordination Agreement and the Operating
Agreement are referred to collectively as the "Transaction Documents" and the
transactions contemplated by the Transaction Documents are referred to
collectively as the "Restructuring".
 
    You have requested our opinion, as investment bankers, as to the fairness,
from a financial point of view, to the Company of the consideration (defined as
(a) the sum of (i) the cash payment of $400 million to be received from Crescent
(including, to the extent assumed by Crescent, the value of any debt assumed by
Crescent) and (ii) the value of Magellan's equity interest in OpCo LESS (b) the
value of the Crescent Warrants and (c) taking into consideration the value
attributable to the Retained Franchise Assets) to be received in Restructuring.
 
    In arriving at the opinion set forth below, we have, among other things:
 
    (1) reviewed executed copies of the Transaction Documents;
 
    (2) reviewed (i) the Annual Reports on Form 10-K and related publicly
       available financial information of the Company for the three most recent
       fiscal years ended September 30, 1996, (ii) the Quarterly Reports on Form
       10-Q and related publicly available financial information of the Company
       for the three most recent quarterly fiscal periods ended June 30, 1996,
       (iii) the Company's definitive Proxy Statement, dated January 25, 1996,
       (iv) the Company's Current Reports on Form 8-K filed since September 30,
       1993 through January 28, 1997, and (v) certain other information,
       including publicly available information, relating to the business,
       earnings, cash flow, assets and prospects of the Company;
 
    (3) reviewed (i) the Annual Reports on Form 10-K and related publicly
       available financial information of Crescent Real Estate Equities Trust, a
       Texas real estate investment trust of which Crescent is the operating
       partnership ("CEI"), for the three most recent fiscal years ended
       December 31, 1995, (ii) the Quarterly Reports on Form 10-Q and related
       publicly available financial information of CEI for the three most recent
       quarterly fiscal periods ended September 30, 1996, (iii) CEI's definitive
       Proxy Statement, dated May 20, 1996, (iv) the Prospectus, dated June 18,
       1996, and the Prospectus Supplement dated September 27, 1996, relating to
       CEI's most recent common stock offering, (v) CEI's Current Reports on
       Form 8-K filed since August 2, 1994 through January 28, 1997, and (vi)
       certain other information, including publicly available information,
       relating to the business, earnings, cash flow, assets and prospects of
       CEI;
 
    (4) reviewed income statement, balance sheet and cash flow forecasts of
       Magellan and its constituent businesses for the fiscal years ended
       September 30, 1997 and 1998, as furnished to us by the Company;
 
    (5) conducted discussions with members of senior management of Magellan
       concerning the past and current business, operations, assets, present
       financial condition and future prospects of the Company and OpCo;
 
    (6) reviewed the historical reported market prices and trading activity for
       the publicly traded securities of Magellan and CEI;
 
    (7) compared certain financial information, operating statistics and market
       trading information relating to Magellan and CEI with published financial
       information, operating statistics and market trading information relating
       to selected public companies that we deemed to be reasonably similar to
       Magellan and CEI, respectively;
 
                              Appendix I - Page 2
<PAGE>
    (8) compared the financial terms of the Restructuring and the Transaction
       Documents with the financial terms, to the extent publicly available, of
       selected other recent transactions that we deemed to be relevant; and
 
    (9) reviewed such other information and financial studies and analyses and
       performed such other investigations and took into account such other
       matters as we deemed necessary including our assessment of general
       economic, market, and monetary conditions.
 
    In preparing our opinion, we have assumed and relied upon the accuracy and
completeness of all financial and other information supplied to us by Magellan,
or that is publicly available, and we have not independently verified such
information. We also have relied upon the management of Magellan as to the
reasonableness and achievability of the financial forecasts of Magellan and its
constituent businesses (and the assumptions and the bases therefor) provided to
us or prepared on the basis of information and assumptions furnished to us and,
with your consent, we have assumed that such forecasts have been reasonably
prepared on the bases reflecting the best currently available estimates and
judgments of such management as to the future operating performance of Magellan
and its constituent businesses. We have not been requested to make, and we have
not made, an independent appraisal or evaluation of the assets, properties,
facilities or liabilities of Magellan or its constituent businesses and we have
not been furnished with any such appraisal or evaluation. We have not
negotiated, or participated in any way in the negotiation of, the terms of the
Restructuring, nor have we advised the Board of Directors of Magellan in
connection with its business decision to enter into the Restructuring in lieu of
any alternative business strategy or any other transactions in which Magellan
may engage. We have assumed that such negotiations took place at arm's length
and in form and substance as related to us by the management of Magellan. We
were not authorized to solicit, and did not solicit, indications of interest
from any third parties with respect to alternative transactions to the
Restructuring, including any sale of Charter. It should be noted that this
opinion necessarily is based upon prevailing market conditions and other
circumstances and conditions as they exist and can be evaluated at this time.
 
    This opinion is addressed to the Board of Directors of the Company and does
not constitute a recommendation to any shareholder as to how such shareholder
should vote on the Restructuring at Magellan's Annual Meeting of Shareholders.
 
    We have acted as financial advisor to the Board of Directors of Magellan in
connection with this transaction and will receive a fee for our services, a
portion of which is contingent on the consummation of this transaction. In
addition, we (i) represented the Board of Directors of Green Spring Health
Services, Inc., a 61%-owned subsidiary of the Company ("Green Spring") in
connection with the Company's acquisition of its controlling interest in Green
Spring, (ii) issued an opinion to the Board of Directors of Green Spring in
connection therewith and (iii) received a fee (plus reimbursement of expenses
and indemnification against certain liabilities) for our services in connection
with such representation. In the ordinary course of our business, we may
actively trade the securities of Magellan and CEI for our own account and for
the accounts of customers and, accordingly, may at any time hold a long or short
position in such securities. Furthermore, in the ordinary course of business, we
provide our clients with research coverage of the Company and CEI.
 
    Since June 1992, we have performed and continue to perform investment
banking and other services for CEI, including acting as a co-manager in certain
underwritten public offerings of securities of CEI, and we have been compensated
for such services. We have also performed and continue to perform investment
banking services for Columbia/HCA Healthcare Corporation, a Delaware corporation
that previously had been an affiliate of Crescent through certain common
ownership interests that have since ceased to exist ("Columbia/HCA"), including
acting as a co-manager in certain underwritten public offerings of securities of
Columbia/HCA and providing mergers and acquisitions advice to Columbia/HCA, and
we have been compensated for such services. The foregoing were ordinary course
arrangements, negotiated at arm's-length by us with CEI and Columbia/HCA, as the
case may be.

    It should be understood that, although subsequent developments may affect
this opinion, we do not have any obligation, express or implied, to update,
revise or reaffirm this opinion.
 
    On the basis of, and subject to the foregoing and other matters that we
consider pertinent, we are of the opinion that, as of the date hereof, the
consideration to be received by Magellan in the Restructuring is fair, from a
financial point of view, to Magellan.
 
Very truly yours,

                    PROPOSED AMENDMENTS TO ARTICLE FIFTH OF
                  THE RESTATED CERTIFICATE OF INCORPORATION OF
                         MAGELLAN HEALTH SERVICES, INC.
     PROPOSED ADDITIONS ARE UNDERLINED. PROPOSED DELETIONS ARE INDICATED BY
                                 OVERSTRIKING.
                                     FIFTH
1.  The number of directors constituting the entire Board shall be twelve eight.
    The number of directors may be changed only by the affirmative vote of at
    least seventy-five percent (75%) of the issued and outstanding shares of the
    Corporation entitled to vote thereon cast at a meeting of the stockholders
    called for such purpose. A director of the Corporation need not be the owner
    of any shares of any class or series of the capital stock of the Corporation
    or a resident of Delaware.
2.  The Board of Directors shall be divided into three classes, as nearly equal
    in numbers as the then total number of directors constituting the entire
    board permits, with the term of office of one class expiring each year.
    Directors of the first class, which shall initially consist of two members,
    shall hold office for terms expiring at the next succeeding annual meeting;
    directors of the second class, which shall initially consist of three
    members, shall hold office for terms expiring at the second succeeding
    annual meeting; and directors of the third class, which shall initially
    consist of three members, shall hold office for terms expiring at the third
    succeeding annual meeting. The terms of the directors in office on the date
    of the effectiveness of the Certificate of Amendment adding this paragraph
    to the Restated Certificate of Incorporation (the "Current Directors") shall
    be modified so that the term of Mr. William A. Fickling, Jr. expires in
    1995, the term of Mr. E. Mac Crawford expires in 1994 and the term of
    Lawrence W. Drinkard expires in 1993 and such directors shall be placed into
    the class of directors whose terms of office correspond to their respective
    modified terms. Upon the filing in the Office of the Secretary of State of
    the State of Delaware of the Certificate of Amendment of the Restated
    Certificate of Incorporation incorporating this amendment, Edwin M. Banks
    shall become a director of the Corporation with a term expiring in 1993 and
    shall be a director of the first class; Michael D. Hernandez and Raymond H.
    Kiefer shall become directors of the Corporation with terms expiring in 1994
    and shall be directors of the second class; and Andre D. Dimitriadis shall
    become a director of the Corporation with a term expiring in 1995 and shall
    be a director of the third class. The Board of Directors so appointed shall
    appoint a fifth Director to a term expiring in 1995, which Director shall be
    a director of the third class. Any vacancies occurring in the Board of
    Directors for any reason, and any directorships resulting from any increase
    in the number of directors, may be filled by the Board of Directors, acting
    by a majority of the directors then in office, although less than a quorum,
    and any director so chosen shall hold office until the next election of the
    class for which such director shall have been chosen and until his successor
    shall be elected and qualified. Subject to the foregoing, at each annual
    meeting of stockholders the successors to the class of directors whose term
    shall then expire shall be elected to hold office for a term expiring at the
    third succeeding annual meeting.
3.  (a) Notwithstanding any other provisions of the Restated Certificate of
    Incorporation or the By-Laws of the Corporation (and notwithstanding the
    fact that some lesser percentage may be specified by law), any director or
    the entire Board of Directors of the Corporation may be removed at any time,
    but only (i) for cause by the affirmative vote of the holders of a majority
    of the issued and outstanding shares of capital stock of the Corporation
    entitled to vote thereon cast at a meeting of the stockholders called for
    that purpose, or (ii) without cause by the affirmative vote of the holders
    of at least seventy-five percent (75%) of the issued and outstanding shares
    of capital stock of the Corporation entitled to vote thereon cast at a
    meeting of the stockholders called for that purpose.
 
                              Appendix II - Page 1

   (b) Election of directors need not be by written ballot unless the By-Laws of
    the Corporation shall so provide.
   (c) The provisions of this Article Fifth shall not be amended, altered,
    changed or repealed except by the affirmative vote of the holders of at
    least seventy-five percent (75%) of the issued and outstanding shares of
    capital stock of the Corporation entitled to vote thereon cast at a meeting
    of the stockholders called for that purpose.

Corporation or otherwise provide for payment of an amount equal to the amount,
if any, which the Corporation at the time of exercise is required to withhold
under the income tax withholding provisions of the Code and other applicable
income tax laws.
 
        (e)  METHOD OF EXERCISE.  All Options shall be exercised (i) by written
    notice directed to the Secretary of the Corporation at its principal of
    business, accompanied by payment of the option exercise price, in accordance
    with the foregoing subsection (d), for the number of shares specified in the
    notice of exercise and by any documents required by Section 14, or (ii) by
    complying with the exercise and other provisions of any broker-directed
    cashless exercise/resale procedure adopted by the Corporation and approved
    by the Committee, and by delivery of any documents required by Section 14.
    The Corporation shall make delivery of such shares within a reasonable
    period of time or in accordance with applicable provisions of any such
    broker-directed cashless exercise/resale procedure; provided, that if any
    law or regulation requires the Corporation to take any action (including but
    not limited to the filing of a registration statement under the Securities
    Act of 1933 and causing such registration statement to become effective)
    with respect to the shares specified in such notice before their issuance,
    then the date of delivery of such shares shall be extended for the period
    necessary to take such action.
 
        (f)  TERM OF OPTIONS.  Except as otherwise specifically provided in the
    Plan, the terms of all Options shall commence on the date of grant and shall
    expire not later than February 28, 2007.
 
        (g)  EXERCISE OF OPTIONS.  Options are exercisable only to the extend
    they are vested as provided in the Stock Option Agreement. After Options
    have vested in accordance with the terms of the Stock Option Agreement, such
    Options are exercisable at anytime, in whole or in part during their terms
    if the Participant is at the time of exercise employed by the Company or a
    Subsidiary. If a Participant's employment with the Corporation or any
    Subsidiary is terminated for any reason other than death or disability, the
    vested portion of each Option held by such Participant on the date of such
    termination may be exercised for six (6) months following the date of
    termination of employment (but not after expiration of the term of the
    Option). In the event of the death or Disability of a Participant, the
    vested portion of each Option held by such Participant on the date of such
    event may be exercised
 
                             Appendix III - Page 3
<PAGE>
    within twelve (12) months of the date of such event (but not after the
    expiration of the term of the Option).
 
    In the event of the death of a Participant, the vested portion of each
Option previously held by such Participant may be exercised within the time set
forth above by the executor, other legal representative or, if none, by the heir
or legatee of such Participant.
 
        (h)  ADJUSTMENTS UPON A CHANGE IN CAPITALIZATION.  Upon a change in
    capitalization pursuant to Section 9, the number of shares covered by an
    Option and the per share option exercise price shall be adjusted in
    accordance with the provisions of Section 9.
 
        (i)  TRANSFERABILITY.  No Option shall be assignable or transferable by
    the Participant except by will or by the laws of descent and distribution.
    The designation of a beneficiary shall not constitute a transfer; and,
    during the lifetime of a Participant, all Options held by such Participant
    shall be exercisable only by him or by his lawful representative in the
    event of his incapacity.
 
        (j)  RIGHTS AS A STOCKHOLDER.  A Participant shall have no rights as a
    stockholder with respect to shares covered by his Option until the date of
    the issuance of the shares to him and only after such shares are fully paid.
    Unless specified in Section 9, no adjustment will be made for dividends or
    other rights for which the record date is prior to the date of such
    issuance.
 
        (k)  MISCELLANEOUS PROVISIONS.  The Stock Option Agreements authorized
    under the Plan may contain such other provisions not inconsistent with the
    terms of this Plan as the Committee shall deem advisable.
 
    8.  VESTING.  Options granted under this Plan shall be exercisable only to
the extent such Options have become vested pursuant to this Section 8. An Option
shall vest at the rate of 33 1/3 percent of the shares covered by the Option on
each of the first three anniversary dates of the grant of the Option if the
Participant is an employee of the Company or a Subsidiary on such dates.
 
    9.  CHANGE IN CAPITALIZATION.  If the Stock should, as a result of a stock
split or stock dividend, combination of shares, recapitalization or other change
in the capital structure of the Corporation or exchange of Stock for other
securities by reclassification or otherwise, be increased or decreased or
changed into, or exchanged for, a different number or kind of shares or other
securities of the Corporation, or any other corporation, then the number of
shares covered by Options, the number and kind of shares which thereafter may be
distributed or issued under the Plan and the per share option price of Options
shall be appropriately adjusted consistent with such change in such manner as
the Committee may deem equitable to prevent dilution of or increase in the
rights granted to, or available for, Participants.
 
    10.  FRACTIONAL SHARES.  In the event that any provision of this Plan or a
Stock Option Agreement would create a right to acquire a fractional share of
Stock, such fractional share shall be disregarded.
 
    11.  SUCCESSOR CORPORATION.  If the Corporation is merged or consolidated
with another corporation or other legal entity and the Corporation is not the
surviving corporation or legal entity, or in the event all or substantially all
of the assets or common stock of the Corporation is acquired by another
corporation or legal entity, or in the case of a dissolution, reorganization or
liquidation of the Corporation, the Board, or the board of directors or
governing body of any corporation or other legal entity assuming the obligations
of the Corporation hereunder, shall either: (i) make appropriate provision for
the preservation of Participants' rights under the Plan in any agreement or plan
it may enter into or adopt to effect any of the foregoing transactions; or (ii)
upon written notice to each Participant, provide that all Options, whether or
not vested, may be exercised within thirty days of the date of such notice and
if not so exercised, shall be terminated.
 
    12.  CHANGE IN CONTROL.  Notwithstanding any provisions in the Plan to the
contrary, in the event of a Change in Control, any unvested and outstanding
Options awarded to Participants under the Plan automatically shall become fully
vested and exercisable in accordance with the terms thereof.
 
                             Appendix III - Page 4
<PAGE>
    13.  NON-ALIENATION OF BENEFITS.  Except insofar as applicable law otherwise
may require, (i) no Options, rights or interest of Participants or Stock
deliverable to any Participant at any time under the Plan shall be subject in
any manner to alienation by anticipation, sale, transfer, assignment,
bankruptcy, pledge, attachment, charge or encumbrance of any kind, and any
attempt to so alienate, sell, transfer, assign, pledge, attach, charge or
otherwise encumber any such amount, whether presently or thereafter payable,
shall be void; and (ii) to the fullest extent permitted by law, the Plan shall
in no manner be liable for, or subject to, claims, liens, attachments or other
like proceedings or the debts, liabilities, contracts, engagements or torts of
any Participant or beneficiary. Nothing in this Section 13 shall prevent a
Participant's rights and interests under the Plan from being transferred by will
or by the laws of descent and distribution; provided, that no transfer by will
or by the laws of descent and distribution shall be effective to bind the
Corporation unless the the Committee or its designee shall have been furnished
before or after the death of such Participant with a copy of such will or such
other evidence as the Committee may deem necessary to establish the validity of
the transfer.
 
    14.  LISTING AND QUALIFICATION OF SHARES.  The Corporation, in its
discretion, may postpone the issuance or delivery of shares of Stock until
completion of any stock exchange listing, or other qualification or registration
of such shares under any state or federal law, rule or regulation, as the
Corporation may consider appropriate, and may require any Participant to make
such representations, including, but not limited to, a written representation
that the shares are to be acquired for investment and not for resale or with a
view to the distribution thereof, and to furnish such information as it may
consider appropriate in connection with the issuance or delivery of the shares
in compliance with applicable law, rules and regulations. The Corporation may
cause a legend or legends to be placed on such certificates to make appropriate
reference to such representation and to restrict transfer in the absence of
compliance with applicable federal or state securities laws.
 
    15.  NO CLAIM OR RIGHT UNDER THE PLAN.  No employee of the Corporation or
any Subsidiary shall at any time have the right to be selected as a Participant
in the Plan nor, having been selected as a Participant and granted an Option, to
be granted any additional Option. Neither the action of the Corporation in
establishing the Plan, nor any action taken by it or by the Board or the
Committee thereunder, nor any provision of the Plan, nor participation in the
Plan, shall be construed to give, and does not give, to any person the right to
be retained in the employ of the Corporation or any Subsidiary, or interfere in
any way with the right of the Corporation or any Subsidiary to discharge or
terminate any person at any time without regard to the effect such discharge or
termination may have upon such person's right, if any, under the Plan.
 
    16.  TAXES.  The Corporation may make such provisions and take such steps as
it may deem necessary or appropriate for the withholding of all federal, state,
local and other taxes required by law to be withheld with respect to Options
under the Plan, including, but not limited to, (i) deducting the amount required
to be withheld from salary or any other amount then or thereafter payable to a
Participant, beneficiary or legal representative, (ii) requiring a Participant,
beneficiary or legal representative to pay to the Corporation the amount
required to be withheld as a condition of releasing the Stock, or (iii)
complying with applicable provisions of any broker-directed cashless
exercise/resale procedure adopted by the Corporation pursuant to Section 7(e).
 
    17.  NO LIABILITY OF DIRECTORS.  No member of the Board or the Committee
shall be personally liable by reason of any contract or other instrument
executed by such member on his behalf in his capacity as a member of the Board
or Committee, nor for any mistake of judgment made in good faith, and the
Corporation shall indemnify and hold harmless each employee, officer and
Director, to whom any duty or power relating to the administration or
interpretation of the Plan may be allocated or delegated, against any cost or
expense (including counsel fees) or liability (including any sum paid in
settlement of a claim with the approval of the Board) arising out of any act or
omission to act in connection with the Plan to the fullest extent permitted or
required by the Corporation's governing instruments and, in addition, to the
fullest extent of any applicable insurance policy purchased by the Corporation.
 
                             Appendix III - Page 5
<PAGE>
    18.  OTHER PLANS.  Nothing contained in the Plan is intended to amend,
modify or rescind any previously approved compensation plans or programs entered
into by the Corporation or its Subsidiaries. The Plan shall be construed to be
in addition to any and all such plans or programs. No award of Options under the
Plan shall be construed as compensation under any other executive compensation
or employee benefit plan of the Corporation or any of its Subsidiaries, except
as specifically provided in any such plan or as otherwise provided by the
Committee. The adoption of the Plan by the Board shall not be construed as
creating any limitations on the power or authority of the Board to adopt such
additional compensation or incentive arrangements as the Board may deem
necessary or desirable.
 
    19.  AMENDMENT OR TERMINATION.  This Plan may be amended by the Board from
time to time to the extent that the Board deems necessary or appropriate;
provided, no such amendment shall be made absent the approval of the
stockholders of the Corporation: (1) if stockholder approval of such amendment
is required for continued compliance with Rule 16b-3 of the Exchange Act, or (2)
if stockholder approval of such amendment is required by any other applicable
laws or regulations or by the rules of any stock exchange as long as the Stock
is listed for trading on such exchange. The Committee also may suspend the
granting of Options under this Plan at any time and may terminate this Plan at
any time; provided, the Corporation shall not have the right to modify, amend or
cancel any Option granted before such suspension or termination unless (1) the
Participant consents in writing to such modification, amendment or cancellation
or (2) there is a dissolution or liquidation of the Corporation or a transaction
described in Section 11 of this Plan.
 
    20.  CAPTIONS.  The captions preceding the sections of the Plan have been
inserted solely as a matter of convenience and shall not, in any manner, define
or limit the scope or intent of any provisions of the Plan.
 
    21.  GOVERNING LAW.  The Plan and all rights thereunder shall be governed
by, and construed in accordance with, the laws of the State of Georgia, without
reference to the principles of conflicts of law thereof.
 
    22.  EXPENSES.  All expenses of administering the Plan shall be borne by the
Corporation.
 
    23.  EFFECTIVE DATE.  The Plan shall be effective as of the date of its
adoption by the Board, subject to approval of this Plan by the stockholders of
the Corporation after the date of its adoption.
