Asset Sale or any Investment or acquisition of assets that would have required
an adjustment pursuant to clause (B) or (C) above if made by the Company or a
Restricted Subsidiary during such period, EBITDA and Consolidated Interest
Expense for such period shall be calculated after giving pro forma effect
thereto as if such Material Asset Sale, Investment or acquisition of assets
occurred on the first day of such period.  For purposes of this definition,
whenever pro forma effect is given for a transaction, the pro forma calculation
shall be made in good faith by a responsible financial or accounting officer of
the Company.  In making such calculations on a pro forma basis, interest
attributable to Indebtedness bearing a floating interest rate shall be computed
as if the rate in effect on the date of computation had been the applicable rate
for the entire period. 



                                                                          7

                                     ARTICLE 2
                                          
                                    The Securities

          SECTION 2.01.  Form and Dating.  Provisions relating to the Initial
Securities, the Private Exchange Securities and the Exchange Securities are set
forth in the Appendix, which is hereby incorporated in and expressly made a part
of this Indenture.  The (i) Initial Securities and the Trustee's certificate of
authentication and (ii) Private Exchange Securities and the Trustee's
certificate of authentication shall each be substantially in the form of
Exhibit A hereto, which is hereby incorporated in and expressly made a part of
this Indenture.  The Exchange Securities and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit B hereto, which is
hereby incorporated in and expressly made a part of this Indenture.  The
Securities may have notations, legends or endorsements required by law, stock
exchange rule, agreements to which the Company is subject, if any, or usage
(provided that any such notation, legend or endorsement shall be in a form
acceptable to the Company).  Each Security shall be dated the date of its
authentication.

          SECTION 2.02.  Execution and Authentication.  One or more Officers
shall sign the Securities for the Company by manual or facsimile signature.

          If an Officer whose signature is on a Security no longer holds that
office at the time the Trustee authenticates the Security, the Security shall be
valid nevertheless.

          A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security.  The
signature shall be 


                                                                          25

conclusive evidence that the Security has been authenticated under this
Indenture.

          The Trustee shall authenticate and make available for delivery
Securities as set forth in the Appendix.

          The Trustee may appoint an authenticating agent reasonably acceptable
to the Company to authenticate the Securities.  Any such appointment shall be
evidenced by an instrument signed by a Trust Officer, a copy of which shall be
furnished to the Company.  Unless limited by the terms of such appointment, an
authenticating agent may authenticate Securities whenever the Trustee may do so.
Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent.  An authenticating agent has the same rights as
any Registrar, Paying Agent or agent for service of notices and demands.   

          SECTION 2.03.  Registrar and Paying Agent.  The Company shall maintain
an office or agency where Securities may be presented for registration of
transfer or for exchange (the "Registrar") and an office or agency where
Securities may be presented for payment (the "Paying Agent").  The Registrar
shall keep a register of the Securities and of their transfer and exchange.  The
Company may have one or more co-registrars and one or more additional paying
agents.  The term "Paying Agent" includes any additional paying agent, and the
term "Registrar" includes any co-registrars.  The Company initially appoints the
Trustee as (i) Registrar and Paying Agent in connection with the Securities, and
(ii) the Securities Custodian (as defined in the Appendix) with respect to the
Global Securities (as defined in the Appendix).

          The Company shall enter into an appropriate agency agreement with any
Registrar or Paying Agent not a party to this Indenture, which shall incorporate
the terms of the TIA.  The agreement shall implement the provisions of this
Indenture that relate to such agent.  The Company shall notify the Trustee of
the name and address of any such agent.  If the Company fails to maintain a
Registrar or Paying Agent, the Trustee shall act as such and shall be entitled
to appropriate compensation therefor pursuant to Section 7.07.  The Company or
any of its domestically organized Wholly-owned Subsidiaries may act as Paying
Agent or Registrar.

          The Company may remove any Registrar or Paying Agent upon written
notice to such Registrar or Paying Agent and to the Trustee; provided, however,
that no such removal 


                                                                          26

shall become effective until (1) acceptance of an appointment by a successor as
evidenced by an appropriate agreement entered into by the Company and such
successor Registrar or Paying Agent, as the case may be, and delivered to the
Trustee or (2) notification to the Trustee that the Trustee shall serve as
Registrar or Paying Agent until the appointment of a successor in accordance
with clause (1) above.  The Registrar or Paying Agent may resign at any time
upon written notice; provided, however, that the Trustee may resign as Paying
Agent or Registrar only if the Trustee also resigns as Trustee in accordance
with Section 7.08.

          SECTION 2.04.  Paying Agent To Hold Money in Trust.  Prior to 11:00
a.m. on each due date of the principal and interest on any Security, the Company
shall deposit with the Paying Agent (or if the Company or a Subsidiary is acting
as Paying Agent, segregate and hold in trust for the benefit of the Persons
entitled thereto) a sum sufficient to pay such principal and interest when so
becoming due.  The Company shall require each Paying Agent (other than the
Trustee) to agree in writing that the Paying Agent shall hold in trust for the
benefit of Securityholders or the Trustee all money held by the Paying Agent for
the payment of principal of or interest on the Securities and shall notify the
Trustee of any default by the Company in making any such payment.  If the
Company or a Subsidiary of the Company acts as Paying Agent, it shall segregate
the money held by it as Paying Agent and hold it as a separate trust fund.  The
Company at any time may require a Paying Agent to pay all money held by it to
the Trustee and to account for any funds disbursed by the Paying Agent.  Upon
complying with this Section, the Paying Agent shall have no further liability
for the money delivered to the Trustee.

          SECTION 2.05.  Securityholder Lists.  The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Securityholders.  If the Trustee is not the
Registrar, the Company shall furnish, or cause the Registrar to furnish, to the
Trustee, in writing at least five Business Days before each interest payment
date and at such other times as the Trustee may request in writing, a list in
such form and as of such date as the Trustee may reasonably require of the names
and addresses of Securityholders.

          SECTION 2.06.  Transfer and Exchange.  The Securities shall be issued
in registered form and shall be transferable only upon the surrender of a
Security for registration of transfer.  When a Security is presented to the
Registrar with a request to register a transfer, the 


                                                                          27

Registrar shall register the transfer as requested if the requirements of
Section 8-401(a)(l) of the Uniform Commercial Code are met.  When Securities are
presented to the Registrar with a request to exchange them for an equal
aggregate principal amount of Securities of other denominations, the Registrar
shall make the exchange as requested if the same requirements are met.  To
permit registration of transfers and exchanges, the Company shall execute and
the Trustee shall authenticate Securities at the Registrar's request.  Upon any
transfer or exchange, the Registrar and the Trustee may require a Holder, among
other things, to furnish appropriate endorsements or transfer documents and to
pay any taxes required by law or permitted by this Indenture. 

          The Company shall not be required to make and the Registrar need not
register transfers or exchanges of Securities selected for redemption (except,
in the case of Securities to be redeemed in part, the portion thereof not to be
redeemed) or any Securities for a period of 15 days before a selection of
Securities to be redeemed.

          Prior to the due presentation for registration of transfer of any
Security, the Company, the Trustee, the Paying Agent or the Registrar may deem
and treat the Person in whose name a Security is registered as the absolute
owner of such Security for the purpose of receiving payment of principal of and
interest, if any, on such Security and for all other purposes whatsoever,
whether or not such Security is overdue, and none of the Company, the Trustee,
the Paying Agent or the Registrar shall be affected by notice to the contrary.

          Any Holder of a Global Security shall, by acceptance of such Global
Security, agree that transfers of beneficial interest in such Global Security
may be effected only through a book-entry system maintained by (i) the Holder of
such Global Security (or its agent) or (ii) any Holder of a beneficial interest
in such Global Security, and that ownership of a beneficial interest in such
Global Security shall be required to be reflected in a book entry.

          All Securities issued upon any transfer or exchange pursuant to the
terms of this Indenture will evidence the same debt and will be entitled to the
same benefits under this Indenture as the Securities surrendered upon such
transfer or exchange.

          SECTION 2.07.  Replacement Securities.  If a mutilated Security is
surrendered to the Registrar or if the 


                                                                          28

Holder of a Security claims that the Security has been lost, destroyed or
wrongfully taken, the Company shall issue and the Trustee shall authenticate a
replacement Security if the Holder (i) notifies the Company or the Trustee
within a reasonable time after he has notice of such loss, destruction or
wrongful taking and the Registrar has not registered a transfer prior to
receiving such notification, (ii) makes such request to the Company or the
Trustee prior to the Security being acquired by a protected purchaser as defined
in Section 8-303 of the Uniform Commercial Code (a "protected purchaser") and
(iii) satisfies any other reasonable requirements of the Trustee and the Company
including, without limitation, the requirements of Section 8-405 of the Uniform
Commercial Code.  If required by the Trustee or the Company, such Holder shall
furnish an indemnity bond sufficient in the reasonable judgment of the Trustee
and the Company to protect the Company, the Trustee, the Paying Agent and the
Registrar from any loss that any of them may suffer if a Security is replaced. 
The Company and the Trustee may charge the Holder for their expenses in
replacing a Security.  In the event any such mutilated, lost, destroyed or
wrongfully taken Security has become or is about to become due and payable, the
Company in its discretion may pay such Security instead of issuing a new
Security in replacement thereof.

          Every replacement Security is an additional obligation of the Company.

          The provisions of this Section 2.07 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, lost, destroyed or wrongfully taken
Securities.

          SECTION 2.08.  Outstanding Securities.  Securities outstanding at any
time are all Securities authenticated by the Trustee except for those canceled
by it, those delivered to it for cancelation and those described in this Section
as not outstanding.  A Security does not cease to be outstanding because the
Company or an Affiliate of the Company holds the Security.

          If a Security is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee and the Company receive proof satisfactory to
them that the replaced Security is held by a protected purchaser.

          If the Paying Agent segregates and holds in trust, in accordance with
this Indenture, on a redemption date or maturity date money sufficient to pay
all principal and 


                                                                          29

interest payable on that date with respect to the Securities (or portions
thereof) to be redeemed or maturing, as the case may be, and the Paying Agent is
not prohibited from paying such money to the Securityholders on that date
pursuant to the terms of this Indenture, then on and after that date such
Securities (or portions thereof) cease to be outstanding and interest on them
ceases to accrue.

          SECTION 2.09.  Temporary Securities.  In the event that Definitive
Securities (as defined in the Appendix) are to be issued under the terms of this
Indenture, until such Definitive Securities are ready for delivery, the Company
may prepare and the Trustee shall authenticate temporary Securities.  Temporary
Securities shall be substantially in the form of Definitive Securities but may
have variations that the Company considers appropriate for temporary Securities.
Without unreasonable delay, the Company shall prepare and the Trustee shall
authenticate Definitive Securities and deliver them in exchange for temporary
Securities upon surrender of such temporary Securities at the office or agency
of the Company, without charge to the Holder.

          SECTION 2.10.  Cancelation.  The Company at any time may deliver
Securities to the Trustee for cancelation.  The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment.  The Trustee and no one else shall cancel all
Securities surrendered for registration of transfer, exchange, payment or
cancelation and deliver canceled Securities to the Company pursuant to written
direction by an Officer.  The Company may not issue new Securities to replace
Securities it has redeemed, paid or delivered to the Trustee for cancelation. 
The Trustee shall not authenticate Securities in place of canceled Securities
other than pursuant to the terms of this Indenture.

          SECTION 2.11.  Defaulted Interest.  If the Company defaults in a
payment of interest on the Securities, the Company shall pay the defaulted
interest (plus interest on such defaulted interest to the extent lawful) in any
lawful manner.  The Company may pay the defaulted interest to the Persons who
are Securityholders on a subsequent special record date.  The Company shall fix
or cause to be fixed any such special record date and payment date to the
reasonable satisfaction of the Trustee and shall promptly mail or cause to be
mailed to each Securityholder a notice that states the special record date, the
payment date and the amount of defaulted interest to be paid.




                                                                             30


          SECTION 2.12.  CUSIP Numbers.  The Company in issuing the Securities
may use "CUSIP" numbers (if then generally in use) and, if so, the Trustee shall
use "CUSIP" numbers in notices of redemption as a convenience to Holders;
provided, however, that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Securities or as
contained in any notice of a redemption and that reliance may be placed only on
the other identification numbers printed on the Securities, and any such
redemption shall not be affected by any defect in or omission of such numbers.


                                     ARTICLE 3

                                      Redemption

          SECTION 3.01.  Notices to Trustee.  If the Company elects to redeem
Securities pursuant to paragraph 5 of the Securities, it shall notify the
Trustee in writing of the redemption date, the principal amount of Securities to
be redeemed and the paragraph of the Securities pursuant to which the redemption
will occur.  

          The Company shall give each notice to the Trustee provided for in this
Section at least 35 days before the redemption date unless the Trustee consents
to a shorter period.  Such notice shall be accompanied by an Officers'
Certificate and an Opinion of Counsel from the Company to the effect that such
redemption will comply with the conditions herein.  If fewer than all the
Securities are to be redeemed, the record date relating to such redemption shall
be selected by the Company and given to the Trustee, which record date shall be
not fewer than 15 days after the date of notice to the Trustee.  Any such notice
may be canceled at any time prior to notice of such redemption being mailed to
any Holder and shall thereby be void and of no effect.
     
          SECTION 3.02.  Selection of Securities To Be Redeemed.  If less than
all of the Securities are to be redeemed at any time, selection of the
Securities for redemption shall be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
Securities are listed or, if the Securities are not listed on a national
securities exchange, on a pro rata basis.  The Trustee shall make the selection
from outstanding Securities not previously called for redemption.  The Trustee
may select for redemption portions of the principal of Securities that have
denominations larger than $1,000.  Securities and portions 



                                                                             31

of them the Trustee selects shall be in amounts of $1,000 or a whole multiple of
$1,000.  Provisions of this Indenture that apply to Securities called for
redemption also apply to portions of Securities called for redemption.  The
Trustee shall notify the Company promptly of the Securities or portions of
Securities to be redeemed.

          SECTION 3.03.  Notice of Redemption.  At least 30 days but not more
than 60 days before a date for redemption of Securities, the Company shall mail
a notice of redemption by first-class mail to each Holder of Securities to be
redeemed at such Holder's registered address.

          The notice shall identify the Securities to be redeemed and shall
state:

          (1) the redemption date;

          (2) the redemption price;

          (3) the name and address of the Paying Agent;

          (4) that Securities called for redemption must be surrendered to the
     Paying Agent to collect the redemption price;

          (5) if fewer than all the outstanding Securities are to be redeemed,
     the certificate numbers and principal amounts of the particular Securities
     to be redeemed;
     
          (6) that, unless the Company defaults in making such redemption
     payment or the Paying Agent is prohibited from making such payment pursuant
     to the terms of this Indenture, interest on Securities (or portion thereof)
     called for redemption ceases to accrue on and after the redemption date;

          (7) the paragraph of the Securities pursuant to which the Securities
     called for redemption are being redeemed;

          (8) the CUSIP number, if any, printed on the Securities being
     redeemed; and

          (9) that no representation is made as to the correctness or accuracy
     of the CUSIP number, if any, listed in such notice or printed on the
     Securities.





                                                                             32

          At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense.  In such event,
the Company shall provide the Trustee with the information required by this
Section.


          SECTION 3.04.  Effect of Notice of Redemption.  Once notice of
redemption is mailed, Securities called for redemption become due and payable on
the redemption date and at the redemption price stated in the notice.  Upon
surrender to the Paying Agent, such Securities shall be paid at the redemption
price stated in the notice, plus accrued interest, if any, to the redemption
date; provided, however,  that if the redemption date is after a regular record
date and on or prior to the interest payment date, the accrued interest shall be
payable to the Securityholder of the redeemed Securities registered on the
relevant record date.  Failure to give notice or any defect in the notice to any
Holder shall not affect the validity of the notice to any other Holder.

          SECTION 3.05.  Deposit of Redemption Price.  Prior to 11:00 a.m. on
the redemption date, the Company shall deposit with the Paying Agent (or, if the
Company or a Subsidiary is the Paying Agent, shall segregate and hold in trust)
money sufficient to pay the redemption price of and accrued interest on all
Securities to be redeemed on that date other than Securities or portions of
Securities called for redemption that have been delivered by the Company to the
Trustee for cancelation.

          SECTION 3.06.  Securities Redeemed in Part.  Upon surrender of a
Security that is redeemed in part, the Company shall execute and the Trustee
shall authenticate for the Holder (at the Company's expense) a new Security
equal in principal amount to the unredeemed portion of the Security surrendered.


                                      ARTICLE 4
                                      Covenants
          SECTION 4.01.  Payment of Securities.  The Company shall promptly pay
the principal of and interest on the Securities on the dates and in the manner
provided in the Securities and in this Indenture.  Principal and interest shall
be considered paid on the date due if on such date the Trustee or the Paying
Agent holds in accordance with this Indenture money sufficient to pay all
principal and interest then due and the Trustee or the Paying Agent, as the case



                                                                             33

may be, is not prohibited from paying such money to the Securityholders on that
date pursuant to the terms of this Indenture.

          The Company shall pay interest on overdue principal at the rate
specified therefor in the Securities, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

          SECTION 4.02.  Provisions of Reports and Other Information.  At all
times while any Security is outstanding, the Company shall timely file with the
SEC and provide a copy to the Trustee and to each Securityholder all such
reports and other information as required by Section 13 or 15(d) of the Exchange
Act, including, without limitation, Forms 10-K, 10-Q and 8-K.  At such time as
the Company is not subject to the reporting requirements of the Exchange Act,
promptly after the same would be required to be filed with the SEC if the
Company then were subject to Section 13 or 15(d) of the Exchange Act, the
Company shall file with the Trustee and supply to each Holder and, upon request,
to any prospective purchaser of Securities, without cost, copies of its
financial statements and certain other reports or information comparable to that
which the Company would have been required to report pursuant to Sections 13 and
15(d) of the Exchange Act, including, without limitation, the information that
would be required by Forms 10-K, 10-Q and 8-K.  The Company also shall comply
with the other provisions of TIA Section  314(a).

          SECTION 4.03.  Limitation on Additional Indebtedness.  (a)  The
Company shall not, and shall not permit any of its Restricted Subsidiaries,
directly or indirectly, to create or Incur any Indebtedness; provided, however,
the Company may Incur Indebtedness if, after giving pro forma effect to the
Incurrence of such Indebtedness and the application of any of the proceeds
therefrom to repay Indebtedness, the Consolidated Cash Interest Coverage Ratio
of the Company for the four most recent consecutive fiscal quarters for which
financial statements are available prior to the date such additional
Indebtedness is Incurred shall be at least (i) 2.00 to 1.00x if such
Indebtedness is Incurred on or prior to the second anniversary of the Closing
Date and (ii) 2.25 to 1.00x if such Indebtedness is Incurred thereafter.  Any
Indebtedness or Capital Stock of a Person existing at the time such Person
becomes a Subsidiary of the Company (whether by merger, consolidation,
acquisition or otherwise) shall be deemed to be Incurred by such Person at the
time it becomes a Subsidiary of the Company.




                                                                             34


          (b)  Notwithstanding Section 4.03(a), the Company and its Restricted
Subsidiaries may Incur the following Indebtedness:

          (i) Indebtedness under the New Credit Agreement and any replacements,
     refundings, refinancings and substitute facility or facilities thereof, in
     whole or in part, and additional facility or facilities (provided that
     Indebtedness under the New Credit Agreement and any such replacements,
     refundings, refinancings and substitute and additional facility or
     facilities, including unused commitments, shall not at any time exceed
     $700 million in aggregate outstanding principal amount (including the
     available undrawn amount of any letters of credit issued under the New
     Credit Agreement and any such replacements, refundings, refinancings, and
     substitute and additional facility or facilities));

          (ii) Indebtedness of the Company and its Restricted Subsidiaries,
     which Indebtedness is in existence on the Closing Date (including any
     existing or future Guarantees of the Company's 11.25% Series A Senior
     Subordinated Notes due 2004, but excluding Indebtedness permitted by
     clause (i) above);

     rate, (D) such Refinancing Indebtedness (1) shall have an Average Life

          (x) Indebtedness under Hedging Obligations entered into for bona fide
     hedging purposes of the Company and not for speculative purposes; provided,
     however, that such Hedging Obligations do not increase the Indebtedness of
     the Company outstanding at any time other than as a result of fluctuations
     in foreign currency exchange rates or interest rates, as applicable, or by
     reason of fees, indemnities and compensation payable thereunder; and

     repurchase, acquisition or retirement, after giving effect to such
     incurrence and such redemption, repurchase, acquisition or retirement, the

     merger and was not incurred, assumed or issued by the Person so acquired or
     merged in contemplation of such acquisition or merger or to provide all or
     any portion of the funds or credit support utilized to consummate such
     acquisition or merger; provided further that such restrictions only 



                                                                             42

          (9) customary provisions contained in leases or other agreements
     entered into in the ordinary course of business or in Indebtedness
     permitted to be Incurred subsequent to the Closing Date pursuant to
     Section 4.03, in each case which do not limit the ability of any Restricted
     Subsidiary to take any of the actions described in clauses (i) through (iv)
     of this Section 4.05 with respect to a material amount of dividends,
     distributions, Indebtedness, loans, advances or sales, leases or transfers
     of properties or assets, as applicable;

          (10) provisions in joint venture agreements and other similar
     agreements in each case related to Permitted Joint Ventures of the Company

                                                                             43

     increases, supplements, refundings, replacements or refinancings are not
     materially more restrictive with respect to such dividend and other payment
     restrictions than those contained in the dividend or other payment
     restrictions prior to such amendment, modification, restatement, renewal,
     increase, supplement, refunding, replacement or refinancing.

          SECTION 4.06.  Limitation on Use of Proceeds from Asset Sales. 
(a)  The Company and its Restricted Subsidiaries shall not, directly or
indirectly, consummate any Asset Sale with or to any Person other than the
Company or a Restricted Subsidiary, unless (i) the Company or such Restricted
Subsidiary, as the case may be, receives consideration at the time of any such
Asset Sale at least equal to the fair market value of the asset sold or
otherwise disposed of, (ii) at least 70% of the net proceeds from such Asset
Sale are received in Cash at closing (unless (A) such Asset Sale is a lease, or
(B) such Asset Sale is in connection with the creation of, Investment in, or
issuance or sale of Equity Interests by, a Permitted Joint Venture of the
Company or of a Restricted Subsidiary or other Permitted Investment) and
(iii) with respect to any Asset Sale involving the Equity Interest of any
Restricted Subsidiary (unless such Restricted Subsidiary is, or as a result of
such Asset Sale would be, a Permitted Joint Venture of the Company or of a
Restricted Subsidiary or other Permitted Investment), the Company shall sell all
of the Equity Interests of such Restricted Subsidiary it owns.  Within 365 days
after the receipt of Net Cash Proceeds in respect of any Asset Sale, the Company
must use all such Net Cash Proceeds either to invest in properties and assets
used in a Healthcare Service Business (including, without limitation, a capital
investment in any Person which becomes a Restricted Subsidiary) or to reduce
Senior Indebtedness; provided that when any non-Cash proceeds are liquidated,
such proceeds (to the extent they are Net Cash Proceeds) will be deemed to be
Net Cash Proceeds at that time.  When the aggregate amount of Excess Proceeds
(as defined below) exceeds $20 million, the Company shall make an offer (the
"Excess Proceeds Offer") to apply the Excess Proceeds to repurchase the
Securities at a purchase price equal to 100% of the principal amount of such
Securities, plus accrued and unpaid interest to the date of purchase (the
"Excess Proceeds Purchase Price"), in accordance with the terms contemplated in
Section 4.06(b).  To the extent that the aggregate principal amount of the
Securities (plus accrued interest thereon) tendered pursuant to the Excess
Proceeds Offer is less than the Excess Proceeds, the Company may use such
deficiency, or a portion thereof, for general corporate 



                                                                             44

purposes.  If the aggregate principal amount of the Securities surrendered by
Holders thereof exceeds the amount of Excess Proceeds, the Company shall select
the Securities to be purchased in accordance with the procedures described under
Section 3.02.  "Excess Proceeds" shall mean any Net Cash Proceeds from an Asset
Sale that is not invested or used to reduce Senior Indebtedness as provided in
the second sentence of this paragraph.  Notwithstanding the foregoing, any Asset
Sale which results in Net Cash Proceeds of less than $5 million and all Asset
Sales (including any Asset Sale which results in Net Cash Proceeds of less than
$5 million) in any twelve consecutive-month period which result in Net Cash
Proceeds of less than $10 million in the aggregate shall not be subject to the
requirement of Section 4.06(a)(ii).

          (b)  Within 10 days following the occurrence of an event which
mandates an Excess Proceeds Offer under Section 4.06(a), the Company shall mail
a notice (along with any other instructions determined by the Company,
consistent with this Section 4.06, that a Holder must follow in order to have
its Securities purchased) to the Trustee and to each Holder stating:

          (1) that the Excess Proceeds Offer is being made pursuant to this
     Section 4.06 and that all Securities tendered and not subsequently
     withdrawn will be accepted for payment and paid for by the Company;

          (2) the Excess Proceeds Purchase Price and the purchase date (which
     shall not be less than 30 days nor more than 60 days after the date such
     notice is mailed) (the "Excess Proceeds Offer Payment Date");

          (3) that any Security not tendered shall continue to accrue interest
     and shall continue to be governed by the terms of this Indenture in all
     respects;

          (4) that, unless the Company defaults in the payment thereof, all
     Securities accepted for payment pursuant to the Excess Proceeds Offer shall
     cease to accrue interest on and after the Excess Proceeds Offer Payment
     Date;

          (5) that Holders electing to have any Securities purchased pursuant to
     an Excess Proceeds Offer will be required to surrender the Securities to be
     purchased to the Paying Agent at the address specified in the notice prior
     to the close of business on the Business Day next 



                                                                             45

     preceding the respective Excess Proceeds Offer Payment Date;

          (6) that Holders will be entitled to withdraw their election on the
     terms and conditions set forth in such notice; and

          (7) that Holders whose Securities are being purchased only in part
     will be issued new Securities equal in principal amount to the unpurchased
     portion of the Securities surrendered; provided that each Security
     purchased and each such new Security issued shall be in a principal amount
     of $1,000 or integral multiples thereof.

          (c)  Holders electing to have a Security purchased shall be required
to surrender the Security, with an appropriate form duly completed, to the
Paying Agent at the address specified in the notice prior to the close of
business on the Business Day next preceding the Excess Proceeds Offer Payment
Date.  Holders shall be entitled to withdraw their election if the Trustee or
the Company receives not later than one Business Day prior to the purchase date
a telegram, telex, facsimile transmission or letter setting forth the name of
the Holder, the principal amount of the Security which was delivered for
purchase by the Holder and a statement that such Holder is withdrawing his
election to have such Security purchased.

          (d)  On (or, in the case of clause (ii) of this Section 4.06(d), at

the Excess Proceeds Offer, (ii) deposit with the Paying Agent immediately
available funds sufficient to pay the Excess Proceeds Purchase Price of all
Securities or portions thereof accepted for payment, and (iii) deliver or cause
to be delivered to the Trustee all Securities so tendered, together with an
Officers' Certificate specifying the Securities or portions thereof tendered to
the Company or the Paying Agent.  The Paying Agent shall promptly mail or
deliver to each holder of Securities so tendered payment in an amount equal to
the Excess Proceeds Purchase Price for such Securities, and the Trustee shall
promptly authenticate and mail or deliver to such Holder one or more
certificates evidencing new Securities equal in aggregate principal amount to
any unpurchased portion of the Securities surrendered; provided that each such
new Security shall be 



                                                                             46

in a principal amount of $1,000 or integral multiples thereof.

          (e) The Company shall comply with the requirements of Regulation 14E
and Rule 13e-4 (other than the filing requirements of such rule) under the
Exchange Act, and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of the Securities pursuant to an Excess Proceeds Offer.  To the
extent that the provisions of any such securities laws or regulations conflict
with provisions of this Section, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations under this Section by virtue thereof.

          SECTION 4.07.  Limitation on Transactions with Affiliates.  (a)  The
Company shall not, and shall not permit any of its Restricted Subsidiaries to,
directly or indirectly, enter into or conduct any transaction (including the
purchase, sale, lease or exchange of any property or the rendering of any
service) with any Affiliate of the Company (an "Affiliate Transaction") (i) on
terms that are materially less favorable to the Company or such Restricted
Subsidiary, as the case may be, than those that could be obtained at the time of
such transaction in arm's-length dealings with a Person who is not such an
Affiliate and (ii) that, in the event such Affiliate Transaction involves an
aggregate amount in excess of $15 million, is not in writing and has not been
approved by a majority of the Disinterested Directors.  In addition, if such
Affiliate Transaction involves an amount in excess of $30 million, a fairness
opinion must be provided by a nationally recognized appraisal or investment
banking firm. 

          (b)  The provisions of Section 4.07(a) shall not prohibit (i) any
Restricted Payment permitted to be paid pursuant to Section 4.04, (ii) any
issuance of securities, or other payments, awards or grants in cash, securities
or otherwise pursuant to, or the funding of, employment arrangements, stock
options and stock ownership plans approved by the Board of Directors,
(iii) loans or advances to employees in the ordinary course of business in
accordance with past practices of the Company, but in any event not to exceed
$7.5 million in the aggregate outstanding at any one time, (iv) the payment of
reasonable fees to directors of the Company and its Subsidiaries who are not
employees of the Company or its Subsidiaries, (v) any transaction between the
Company and a Restricted Subsidiary or between Restricted Subsidiaries or (vi)



                                                                             47

arrangements in existence as of the date hereof with Persons that employ staff
providers and which provide service exclusively on behalf of the Company and its
Subsidiaries, which arrangements are not material to the Company and its
Subsidiaries taken as a whole.

          SECTION 4.08.  Change of Control.  (a)  Upon the occurrence of a
Change of Control, each Holder shall have the right to require that the Company
repurchase all or any part of such Holder's Securities (the "Change of Control
Offer") at a purchase price in cash equal to 101% of the aggregate principal
amount thereof plus accrued and unpaid interest, if any, to the date of purchase
(subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date), in accordance with
the terms contemplated in Section 4.08(b); provided, however, that
notwithstanding the occurrence of a Change in Control, the Company shall not be
obligated to purchase the Securities pursuant to this Section 4.08 in the event
that it has exercised its right to redeem all the Securities under paragraph 5
of the Securities.  In the event that at the time of such Change of Control the
terms of the Bank Indebtedness restrict or prohibit the repurchase of Securities
pursuant to this Section 4.08, then prior to the mailing of the notice to
Holders provided for in Section 4.08(b), the Company shall (i) repay in full all
Bank Indebtedness or offer to repay in full all Bank Indebtedness and repay the
Bank Indebtedness of each lender who has accepted such offer or (ii) (x) obtain
any requisite consent under the agreements governing the Bank Indebtedness to
permit the repurchase of Securities as provided for in this Section 4.08 or (y)
deliver to the Trustee an Officers' Certificate stating that no such consent is
required. 

          (b)  Within 10 days following any Change of Control (except as
provided in the proviso to the first sentence of Section 4.08(a)), the Company
shall mail a notice (along with any other instructions determined by the
Company, consistent with this Section 4.08, that a Holder must follow in order
to have its Securities purchased) to the Trustee and to each Holder stating:

          (1) that the Change of Control Offer is being made pursuant to
     Section 4.08 of this Indenture and that all Securities tendered and not
     subsequently withdrawn shall be accepted for payment and paid for by the
     Company; 




                                                                             48


          (2) the purchase price and the purchase date (which shall not be less
     than 30 days nor more than 60 days after the date such notice is mailed)
     (the "Change of Control Payment Date"); 

          (3) that any Security not tendered shall continue to accrue interest
     and shall continue to be governed by the terms of this Indenture in all
     respects; 

          (4) that, unless the Company defaults in the payment thereof, all
     Securities accepted for payment pursuant to the Change of Control Offer
     shall cease to accrue interest on and after the Change of Control Payment
     Date; 

          (5) that Holders electing to have any Securities purchased pursuant to
     a Change of Control Offer will  be required to surrender the Securities to
     be purchased to the Paying Agent at the address specified in the notice
     prior to the close of business on the Business Day next preceding the
     Change of Control Payment Date; 

          (6) that Holders shall be entitled to withdraw their election on the
     terms and conditions set forth in such notice;

          (7) that Holders whose Securities are being purchased only in part
     shall be issued new Securities equal in principal amount to the unpurchased
     portion of the Securities surrendered; provided that each Security
     purchased and each such new Security issued shall be in a principal amount
     of $1,000 or integral multiples thereof; and

          (8) the circumstances and relevant facts as determined by the Company
     regarding such Change of Control.

          (c)  Holders electing to have a Security purchased shall be required
to surrender the Security, with an appropriate form duly completed, to the
Paying Agent at the address specified in the notice prior to the close of
business on the Business Day next preceding the Change of Control Payment Date. 
Holders shall be entitled to withdraw their election if the Trustee or the
Company receives not later than one Business Day prior to the purchase date a
telegram, telex, facsimile transmission or letter setting forth the name of the
Holder, the principal amount of the Security which was delivered for purchase by
the Holder and 




                                                                             49

a statement that such Holder is withdrawing his election to have such Security
purchased.

          (d)  On (or, in the case of clause (ii) of this Section 4.08(d), at
the Company's election, before) the Change of Control Payment Date, the Company
shall (i) accept for payment all Securities or portions thereof tendered and not
theretofore withdrawn, pursuant to the Change of Control Offer, (ii) deposit
with the Paying Agent immediately available funds sufficient to pay the purchase
price of all Securities or portions thereof accepted for payment, and
(iii) deliver or cause to be delivered to the Trustee all Securities so
tendered, together with an Officers' Certificate specifying the Securities or
portions thereof tendered to the Company or the Paying Agent.  The Paying Agent
shall promptly mail or deliver to each Holder of Securities so tendered payment
in an amount equal to the purchase price for such Securities, and the Trustee
shall promptly authenticate and mail or deliver to such Holder one or more
certificates evidencing new Securities equal in aggregate principal amount to
any unpurchased portion of the Securities surrendered; provided that each such
new Security shall be in a principal amount of $1,000 or integral multiples
thereof.  The Company shall publicly announce the results of the Change of
Control Offer on or as soon as practicable after the Change of Control Payment
Date. 

          (e)  Notwithstanding the foregoing provisions of this Section, the
Company will not be required to make a Change of Control Offer upon a Change of
Control if a third party makes the Change of Control Offer in the manner, at the
times and otherwise in compliance with the requirements set forth in
Section 4.08(b) applicable to a Change of Control Offer made by the Company and
purchases all Securities validly tendered and not withdrawn under such Change of
Control Offer.  

          (f)  The Company shall comply with the requirements of Regulation 14E
and Rule 13e-4 (other than the filing requirements of such rule) under the
Exchange Act, and any other securities laws and regulations thereunder that are
applicable in connection with the repurchase of the Securities resulting from a
Change of Control.  To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section, the Company shall comply
with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations under this Section by virtue thereof.




                                                                             50


          SECTION 4.09.  Compliance Certificate.  The Company shall deliver to
the Trustee within 120 days after the end of each fiscal year of the Company an
Officers' Certificate stating that in the course of the performance by the
signers of their duties as Officers of the Company they would normally have
knowledge of any Default and whether or not the signers know of any Default that
occurred during such period.  If they do, the certificate shall describe the
Default, its status and what action the Company is taking or proposes to take
with respect thereto.  The Company also shall comply with Section 314(a)(4) of
the TIA.

          SECTION 4.10.  Further Instruments and Acts.  Upon request of the
Trustee, the Company shall execute and deliver such further instruments and do
such further acts as may be reasonably necessary or proper to carry out more
effectively the purpose of this Indenture.

          SECTION 4.11.  Limitation on Liens.  The Company shall not, and shall
not permit any of its Restricted Subsidiaries to, directly or indirectly,
create, incur, assume or suffer to exist any Lien on any of their respective
assets, now owned or hereafter acquired, securing any Indebtedness that is pari
passu with or subordinated in right of payment to the Securities, unless the
Securities are equally and ratably secured; provided that if such Indebtedness
is by its terms expressly subordinate or junior in right of payment to the
Securities, the Lien securing such subordinate or junior Indebtedness shall be
subordinate and junior to the Lien securing the Securities with the same
relative priority as such subordinated or junior Indebtedness shall have with
respect to the Securities.  The Company and its Restricted Subsidiaries may at
any time, directly or indirectly, create, incur, assume or suffer to exist any
Lien on any of their respective assets, now owned or hereafter acquired,
securing any Senior Indebtedness permitted under Section 4.03.


                                     ARTICLE 5
                                          
                                 Successor Company

          SECTION 5.01.  Merger, Consolidation or Sale of Assets.  (a)  The
Company shall not consolidate with, merge with or into, or transfer all or
substantially all of its assets (in one transaction or a series of related



                                                                             51

transactions) to, any Person or permit any party to merge with or into it
unless:

          (i) the Company shall be the continuing Person, or the Person (if
     other than the Company) (the "Successor Company") formed by such
     consolidation or into or with which the Company is merged or to which the
     properties and assets of the Company are transferred shall be a corporation
     organized and existing under the laws of the United States or any State
     thereof or the District of Columbia and shall expressly assume, by a
     supplemental indenture, executed and delivered to the Trustee, in form
     satisfactory to the Trustee, all of the obligations of the Company under
     the Securities and this Indenture and this Indenture remains in full force
     and effect; 

          (ii) immediately before and immediately after giving effect to such
     transaction (and treating any Indebtedness which becomes an obligation of
     the Company, the Successor Company or any Restricted Subsidiary as a result
     of such transaction as having been incurred by the Company, the Successor
     Company or such Restricted Subsidiary at the time of such transaction), no
     Event of Default or Default shall have occurred and be continuing; 

          (iii) except in the case of a merger of the Company with a
     Wholly-owned Subsidiary (which does not have assets or liabilities in
     excess of $1 million) of a newly-formed holding company for the sole
     purpose of forming a holding company structure, the Company or the
     Successor Company, as applicable, could, after giving pro forma effect to
     such transaction, Incur $1.00 of Indebtedness pursuant to Section 4.03(a);
     and 

          (iv) the Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that such
     consolidation, merger or transfer and such supplemental indenture (if any)
     comply with this Indenture (provided that the Opinion of Counsel will not
     be required to cover compliance with any financial tests or financial
     covenants). 

          (b)  Notwithstanding clauses (ii) and (iii) of Section 5.01(a),
(a) any Restricted Subsidiary may consolidate with, merge into or transfer all
or part of its properties and assets to the Company or another Restricted
Subsidiary and (b) the Company may merge with an Affiliate 




                                                                             52

incorporated solely for the purpose of reincorporating the Company in another

and may exercise every right and power of, the Company under this Indenture, and
the predecessor Company in the case of a conveyance, transfer or lease of all or
substantially all its assets shall be released from all obligations under this
Indenture, including, without limitation, any obligation to pay the principal of

                                     ARTICLE 6
                                          
                               Defaults and Remedies

          SECTION 6.01.  Events of Default.  An "Event of Default" occurs if:

          (1) the Company defaults in any payment of interest on any Security
     when the same becomes due and payable, whether or not such payment shall be
     prohibited by Article 10, and such default continues for a period of
     30 days;

          (2) the Company (i) defaults in the payment of the principal of any
     Security when the same becomes due and payable at its Stated Maturity, upon
     redemption, upon acceleration or otherwise, whether or not such payment
     shall be prohibited by Article 10 or (ii) fails to redeem or purchase
     Securities when required pursuant to this Indenture or the Securities,
     whether or not such redemption or purchase shall be prohibited by Article
     10;

          (3) the Company fails to comply with Section 5.01;
     
          (4) the Company fails to comply in any respect with any of its
     agreements in the Securities or this Indenture (other than those referred
     to in (1), (2) or (3) above) and such failure continues for 30 days after
     receipt of the notice specified in the penultimate paragraph of this
     Section 6.01;

          (5) default under any mortgage, indenture or instrument under which
     there may be issued or by which there may be secured or evidenced any
     Indebtedness of the Company or any of its Restricted Subsidiaries (or the
     payment of which is guaranteed by the Company or 



                                                                             53

     any of its Restricted Subsidiaries) whether such Indebtedness is now
     existing or hereafter created, which default results from the failure to
     pay any such Indebtedness at its stated final maturity or results in the
     acceleration of such Indebtedness prior to its stated final maturity and
     the aggregate principal amount of such Indebtedness is at least
     $20 million, or the principal amount of such Indebtedness, together with
     the principal amount of any other such Indebtedness the maturity of which
     has been accelerated, aggregates $35 million or more; 

          (6) the Company or any Restricted Subsidiary pursuant to or within the
     meaning of any Bankruptcy Law:

               (A) commences a voluntary case;

               (B) consents to the entry of an order for relief against it in an
          involuntary case;

               (C) consents to the appointment of a Custodian of it or for any
          substantial part of its property; or 

               (D) makes a general assignment for the benefit of its creditors;

     or takes any comparable action under any foreign laws relating to
     insolvency;

          (7) a court of competent jurisdiction enters an order or decree under
     any Bankruptcy Law that:

               (A) is for relief against the Company or any Restricted
          Subsidiary in an involuntary case;

               (B) appoints a Custodian of the Company or any Restricted
          Subsidiary or for any substantial part of its property; or

               (C) orders the winding up or liquidation of the Company or any
          Restricted Subsidiary;

     or any similar relief is granted under any foreign laws, and in each case
     the order or decree remains unstayed and in effect for 60 days;

          (8) the Company or any Restricted Subsidiary fails to pay final
     judgments aggregating in excess of 




                                                                             54
     $20 million which judgments are not paid, discharged or stayed within
     60 days after their entry.

          The foregoing shall constitute Events of Default whatever the reason
for any such Event of Default and whether it is voluntary or involuntary or is
effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental
body.

          The term "Bankruptcy Law" means Title 11, United States Code, or any
similar Federal or state law for the relief of debtors.  The term "Custodian"
means any receiver, trustee, assignee, liquidator, custodian or similar official
under any Bankruptcy Law.

          A Default under clause (4) is not an Event of Default until the
Trustee or the Holders of at least 25% in aggregate principal amount of the
outstanding Securities notify the Company of the Default and the Company does
not cure such Default within the time specified after receipt of such notice. 
Such notice must be in writing and specify the Default, demand that it be
remedied and state that such notice is a "Notice of Default".

          The Company shall deliver to the Trustee, within 30 days after
becoming aware of the occurrence thereof, written notice in the form of an
Officers' Certificate of any Event of Default and any event which with the
giving of notice or the lapse of time would become an Event of Default, its
status and what action the Company is taking or proposes to take with respect
thereto.

          SECTION 6.02.  Acceleration.  If an Event of Default (other than an
Event of Default specified in Section 6.01(6) or (7) with respect to the
Company) occurs and is continuing, the Trustee by notice to the Company, or the
Holders of at least 25% of the principal amount of the Securities then
outstanding, by written notice to the Company (and to the Trustee if such notice
is given by such Holders) (the "Acceleration Notice"), may, and the Trustee at
the request of such Holders shall, declare all unpaid principal of, and accrued
interest on, such Securities to be due and payable immediately.  Upon a
declaration of acceleration, such principal and accrued interest shall be due
and payable.  If an Event of Default specified in Section 6.01(6) or (7) with
respect to the Company occurs, all unpaid principal of and accrued interest on
the Securities then outstanding shall ipso facto become and be immediately due
and payable without any declaration or other 



                                                                             55

act on the part of the Company, the Trustee or any Holder.  The Holders of a
majority of the aggregate principal amount of the Securities outstanding by
notice to the Trustee may rescind an acceleration and its consequences if the
rescission would not conflict with any judgment or decree and if all existing
Events of Default have been cured or waived except nonpayment of principal or
interest that has become due solely because of acceleration.  No such rescission
shall affect any subsequent Default or impair any right consequent thereto.

          SECTION 6.03.  Other Remedies.  If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of or interest on the Securities or to enforce the performance of
any provision of the Securities or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Securityholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default.  No remedy is
exclusive of any other remedy.  All available remedies are cumulative.

          SECTION 6.04.  Waiver of Past Defaults.  The Holders of a majority in
aggregate principal amount of the outstanding Securities by notice to the
Trustee may waive an existing Default or Event of Default and its consequences,
except (i) a Default in the payment of the principal of or interest on a
Security or (ii) a Default in respect of a provision that under Section 9.02
cannot be amended without the consent of each Securityholder affected.  When a
Default or Event of Default is waived, it is cured and ceases to exist, but no
waiver shall extend to any subsequent or other Default or impair any consequent
right. 

          SECTION 6.05.  Control by Majority.  The Holders of a majority in
principal amount of the Securities may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee.  However, the Trustee
may refuse to follow any direction that conflicts with law or this Indenture or,
subject to Section 7.01, that the Trustee determines is unduly prejudicial to
the rights of other Securityholders or would involve the Trustee in personal
liability; provided, however, that the Trustee may take any other action deemed
proper by the Trustee that is not inconsistent with such direction.  Prior to
taking any 



                                                                             56

action hereunder, the Trustee shall be entitled to indemnification by the
Securityholders satisfactory to it in its sole discretion against all losses and
expenses caused by taking or not taking such action.

          SECTION 6.06.  Limitation on Suits.  Except to enforce the right to
receive payment of principal or interest when due, no Securityholder may pursue
any remedy with respect to this Indenture or the Securities unless:

          (1) the Holder gives to the Trustee written notice stating that an
     Event of Default is continuing;

          (2) the Holders of at least 25% in principal amount of the Securities
     outstanding make a written request to the Trustee to pursue the remedy;

          (3) such Holder or Holders offer to the Trustee indemnity or security
     satisfactory to the Trustee against any loss, liability or expense; 

          (4) the Trustee does not comply with the request within 30 days after
     receipt thereof and the offer of indemnity or security; and 

          (5) during such 30-day period the Holders of a majority of the
     aggregate principal amount of the outstanding Securities do not give the
     Trustee a direction which is inconsistent with the request. 

          A Securityholder may not use this Indenture to prejudice the rights of
another Securityholder or to obtain a preference or priority over another
Securityholder.

          SECTION 6.07.  Rights of Holders to Receive Payment.  Notwithstanding
any other provision of this Indenture, the right of any Holder to receive
payment of principal of and liquidated damages and interest on the Securities
held by such Holder, on or after the respective due dates expressed in the
Securities, or to bring suit for the enforcement of any such payment on or after
such respective dates, shall not be impaired or affected without the consent of
such Holder.

          SECTION 6.08.  Collection Suit by Trustee.  If an Event of Default
specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount then due and owing (together 



                                                                             57

with interest on any unpaid interest to the extent lawful) and the amounts
provided for in Section 7.07.

          SECTION 6.09.  Trustee May File Proofs of Claim.  The Trustee may file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Securityholders
allowed in any judicial proceedings relative to the Company, any Subsidiary,
their creditors or their property and, unless prohibited by law or applicable
regulations, may vote on behalf of the Holders in any election of a trustee in
bankruptcy or other Person performing similar functions, and may become a
member, voting or nonvoting, of any committee of creditors appointed in any such
judicial proceedings.  Any Custodian in any such judicial proceeding is hereby
authorized by each Holder to make payments to the Trustee and, in the event that
the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and its counsel, and any other amounts due the Trustee under Section 7.07.

          SECTION 6.10.  Priorities.  If the Trustee collects any money or
property pursuant to this Article 6, it shall pay out the money or property in
the following order:

          FIRST:  to the Trustee for amounts due under Section 7.07;

          SECOND:  to Holders of Senior Indebtedness of the Company to the
     extent required by Article 10;

          THIRD:  to Securityholders for amounts due and unpaid on the
     Securities for principal and interest, ratably, and any liquidated damages
     without preference or priority of any kind, according to the amounts due
     and payable on the Securities for principal, any liquidated damages and
     interest, respectively; and

          FOURTH:  to the Company.

          The Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section.  At least 15 days before such record
date, the Trustee shall mail to each Securityholder and the Company a notice
that states the record date, the payment date and amount to be paid.




                                                                             58


          SECTION 6.11.  Undertaking for Costs.  In any suit for the enforcement
of any right or remedy under this Indenture or in any suit against the Trustee
for any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees, against any party litigant in the
suit, having due regard to the merits and good faith of the claims or defenses
made by the party litigant.  This Section does not apply to a suit by the
Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of
more than 10% in principal amount of the Securities.

          SECTION 6.12.  Waiver of Stay or Extension Laws.  The Company (to the
extent it may lawfully do so) shall not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Company (to
the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and shall not hinder, delay or impede the execution
of any power herein granted to the Trustee, but shall suffer and permit the
execution of every such power as though no such law had been enacted.


                                     ARTICLE 7
                                          
                                      Trustee

          SECTION 7.01.  Duties of Trustee.  (a)  If an Event of Default has
occurred and is continuing, the Trustee shall exercise the rights and powers
vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent Person would exercise or use under the circumstances
in the conduct of such Person's own affairs.

          (b)  Except during the continuance of an Event of Default:

          (1) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture and no implied covenants or
     obligations shall be read into this Indenture against the Trustee; and

          (2) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the 



                                                                             59

     statements and the correctness of the opinions expressed therein, upon
     certificates or opinions furnished to the Trustee and conforming to the
     requirements of this Indenture.  However, the Trustee shall examine the
     certificates and opinions to determine whether or not they conform to the
     requirements of this Indenture.

          (c)  The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own wilful misconduct,
except that:

          (1) this paragraph does not limit the effect of paragraph (b) of this
     Section;

          (2) the Trustee shall not be liable for any error of judgment made in
     good faith by a Trust Officer unless it is proved that the Trustee was
     negligent in ascertaining the pertinent facts; and

          (3) the Trustee shall not be liable with respect to any action it
     takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Section 6.05.

          (d)  Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section.

          (e)  The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.

          (f)  Money held in trust by the Trustee need not be segregated from
other funds except to the extent required by law.

          (g)  No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties hereunder or in the exercise of any of its
rights or powers, if it shall have reasonable grounds to believe that repayment
of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.

          (h)  Every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section and to the provisions of the TIA.




                                                                             60


    SECTION 7.02.  Rights of Trustee.  (a)  The Trustee may rely on any 
document believed by it to be genuine and to have been signed or presented by 
the proper person.  The Trustee need not investigate any fact or matter 
stated in the document.

    (b)  Before the Trustee acts or refrains from acting, it may require an 
Officers' Certificate or an Opinion of Counsel (provided that the Opinion of 
Counsel will not be required to cover compliance with any financial tests or 
financial covenants).  The Trustee shall not be liable for any action it 
takes or omits to take in good faith in reliance on the Officers' Certificate 
or Opinion of Counsel.

    (c)  The Trustee may act through agents and shall not be responsible for 
the misconduct or negligence of any agent appointed with due care.

    (d)  The Trustee shall not be liable for any action it takes or omits to 
take in good faith which it believes to be authorized or within its rights or 
powers; provided, however, that the Trustee's conduct does not constitute 
wilful misconduct or negligence.

    (e)  The Trustee may consult with counsel, and the advice or opinion of 
counsel with respect to legal matters relating to this Indenture and the 
Securities shall be full and complete authorization and protection from 
liability in respect to any action taken, omitted or suffered by it hereunder 
in good faith and in accordance with the advice or opinion of such counsel.

    (f)  The Trustee shall not be bound to make any investigation into the 
facts or matters stated in any resolution, certificate, statement, 
instrument, opinion, report, notice, request, consent, order, approval, bond, 
debenture, note or other paper or document unless requested in writing to do 
so by the Holders of not less than a majority in principal amount of the 
Securities at the time outstanding, but the Trustee, in its discretion, may 
make such further inquiry or investigation into such facts or matters as it 
may see fit, and, if the Trustee shall determine to make such further inquiry 
or investigation, it shall be entitled to examine the books, records and 
premises of the Company, personally or by agent or attorney, upon reasonable 
notice to the Company and during normal business hours.  

    SECTION 7.03.  Individual Rights of Trustee.  The Trustee in its 
individual or any other capacity may become 



                                                                             61

the owner or pledgee of Securities and may otherwise deal with the Company or 
its Affiliates with the same rights it would have if it were not Trustee.  
Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same 
with like rights.  However, the Trustee must comply with Sections 7.10 and 
7.11.

    SECTION 7.04.  Trustee's Disclaimer.  The Trustee shall not be 
responsible for and makes no representation as to the validity or adequacy of 
this Indenture or the Securities, it shall not be accountable for the 
Company's use of the proceeds from the Securities, and it shall not be 
responsible for any statement of the Company in this Indenture or in any 
document issued in connection with the sale of the Securities or in the 
Securities other than the Trustee's certificate of authentication.

    SECTION 7.05.  Notice of Defaults.  If a Default or an Event of Default 
occurs and is continuing and if it is known to the Trustee, the Trustee shall 
mail to each Securityholder notice of the Default or Event of Default within 
90 days after it becomes known to the Trustee, unless such Default or Event 
of Default has been cured or waived.  Except in the case of a Default or an 
Event of Default in the payment of principal of or interest on any Security, 
the Trustee may withhold the notice if and so long as a committee of its 
Trust Officers in good faith determines that withholding the notice is in the 
interest of the Securityholders. 

    SECTION 7.06.  Reports by Trustee to Holders.  As promptly as practicable 
after each February 1 beginning with the February 1 following the date of 
this Indenture, and in any event prior to April 1 in each year, the Trustee 
shall mail to each Securityholder a brief report dated as of February 1 that 
complies with Section 313(a) of the TIA.  The Trustee shall also comply with 
Section 313(b) of the TIA.

    A copy of each report at the time of its mailing to Securityholders shall 
be filed with the SEC and each stock exchange (if any) on which the 
Securities are listed.  The Company agrees to notify promptly the Trustee 
whenever the Securities become listed on any stock exchange and of any 
delisting thereof.

    SECTION 7.07.  Compensation and Indemnity.  The Company shall pay to the 
Trustee from time to time reasonable compensation for its services.  The 
Trustee's compensation shall not be limited by any law on compensation 



                                                                             62

of a trustee of an express trust.  The Company shall reimburse the Trustee 
upon request for all reasonable out-of-pocket expenses incurred or made by 
it, including costs of collection, in addition to the compensation for its 
services. Such expenses shall include the reasonable compensation and 
expenses, disbursements and advances of the Trustee's agents, counsel, 
accountants and experts.  The Company shall indemnify the Trustee against any 
and all loss, liability or expense (including reasonable attorneys' fees) 
incurred by or in connection with the administration of this trust and the 
performance of its duties hereunder.  The Trustee shall notify the Company of 
any claim for which it may seek indemnity promptly upon obtaining actual 
knowledge thereof; provided, however, that any failure so to notify the 
Company shall not relieve the Company of its indemnity obligations hereunder. 
 The Company shall defend the claim and the indemnified party shall provide 
reasonable cooperation at the Company's expense in the defense.  Such 
indemnified parties may have separate counsel and the Company shall pay the 
reasonable fees and expenses of such counsel; provided, however, that the 
Company shall not be required to pay such fees and expenses if it assumes 
such indemnified parties' defense and, in such indemnified parties' 
reasonable judgment, there is no conflict of interest between the Company and 
such parties in connection with such defense.  The Company need not reimburse 
any expense or indemnify against any loss, liability or expense incurred by 
an indemnified party through such party's own wilful misconduct, negligence 
or bad faith.

    To secure the Company's payment obligations in this Section, the Trustee 
shall have a lien prior to the Securities on all money or property held or 
collected by the Trustee other than money or property held in trust to pay 
principal of and interest and any liquidated damages on particular Securities.

    The Company's payment obligations pursuant to this Section shall survive 
the satisfaction or discharge of this Indenture, any rejection or termination 
of this Indenture under any bankruptcy law or the resignation or removal of 
the Trustee.  When the Trustee incurs expenses after the occurrence of a 
Default specified in Section 6.01(6) or (7) with respect to the Company, the 
expenses are intended to constitute expenses of administration under the 
Bankruptcy Law.

    SECTION 7.08.  Replacement of Trustee.  The Trustee may resign at any 
time by so notifying the Company.  The Holders of a majority in principal 
amount of the 



                                                                             63

Securities may remove the Trustee by so notifying the Trustee and may appoint 
a successor Trustee.  The Company shall remove the Trustee if:

         (1) the Trustee fails to comply with Section 7.10;

         (2) the Trustee is adjudged bankrupt or insolvent;

         (3) a receiver or other public officer takes charge of the Trustee or
    its property; or

         (4) the Trustee otherwise becomes incapable of acting.

    If the Trustee resigns, is removed by the Company or by the Holders of a 
majority in principal amount of the Securities and such Holders do not 
reasonably promptly appoint a successor Trustee, or if a vacancy exists in 
the office of Trustee for any reason (the Trustee in such event being 
referred to herein as the retiring Trustee), the Company shall promptly 
appoint a successor Trustee.

    A successor Trustee shall deliver a written acceptance of its appointment 
to the retiring Trustee and to the Company.  Thereupon the resignation or 
removal of the retiring Trustee shall become effective, and the successor 
Trustee shall have all the rights, powers and duties of the Trustee under 
this Indenture.  The successor Trustee shall mail a notice of its succession 
to Securityholders.  The retiring Trustee shall promptly transfer all 
property held by it as Trustee to the successor Trustee, subject to the lien 
provided for in Section 7.07.

    If a successor Trustee does not take office within 60 days after the 
retiring Trustee resigns or is removed, the retiring Trustee or the Holders 
of 10% in principal amount of the Securities may petition any court of 
competent jurisdiction for the appointment of a successor Trustee.

    If the Trustee fails to comply with Section 7.10, any Securityholder may 
petition any court of competent jurisdiction for the removal of the Trustee 
and the appointment of a successor Trustee.

    Notwithstanding the replacement of the Trustee pursuant to this Section, 
the Company's obligations under Section 7.07 shall continue for the benefit 
of the retiring Trustee.



                                                                             64


    SECTION 7.09.  Successor Trustee by Merger.  If the Trustee consolidates 
with, merges or converts into, or transfers all or substantially all its 
corporate trust business or assets to, another corporation or banking 
association, the resulting, surviving or transferee corporation without any 
further act shall be the successor Trustee.

    In case at the time such successor or successors by merger, conversion or 
consolidation to the Trustee shall succeed to the trusts created by this 
Indenture any of the Securities shall have been authenticated but not 
delivered, any such successor to the Trustee may adopt the certificate of 
authentication of any predecessor trustee, and deliver such Securities so 
authenticated; and in case at that time any of the Securities shall not have 
been authenticated, any successor to the Trustee may authenticate such 
Securities either in the name of any predecessor hereunder or in the name of 
the successor to the Trustee; and in all such cases such certificates shall 
have the full force that certificates of the Trustee are provided anywhere in 
the Securities or in this Indenture. 

    SECTION 7.10.  Eligibility; Disqualification.  The Trustee shall at all 
times satisfy the requirements of TIA Section  310(a).  The Trustee shall 
have a combined capital and surplus of at least $100,000,000 as set forth in 
its most recent published annual report of condition.  The Trustee shall 
comply with TIA Section  310(b); provided, however, that there shall be 
excluded from the operation of TIA Section  310(b)(1) any indenture or 
indentures under which other securities or certificates of interest or 
participation in other securities of the Company are outstanding if the 
requirements for such exclusion set forth in TIA Section  310(b)(1) are met.

    SECTION 7.11.  Preferential Collection of Claims Against Company.  The 
Trustee shall comply with TIA Section  311(a), excluding any creditor 
relationship listed in TIA Section  311(b).  A Trustee who has resigned or 
been removed shall be subject to TIA Section  311(a) to the extent indicated.

                                     ARTICLE 8
                                          
                         Discharge of Indenture; Defeasance

    SECTION 8.01.  Discharge of Liability on Securities; Defeasance. (a)  
When (i) the Company delivers to the Trustee all outstanding Securities 
(other than Securities replaced pursuant to Section 2.07) for 



                                                                             65

cancelation or (ii) all outstanding Securities have become due and payable, 
whether at maturity or as a result of the mailing of a notice of redemption 
pursuant to Article 3 hereof and the Company irrevocably deposits with the 
Trustee funds or U.S. Government Obligations on which payment of principal 
and interest when due will be sufficient to pay at maturity or upon 
redemption all outstanding Securities, including interest thereon to maturity 
or such redemption date (other than Securities replaced pursuant to Section 
2.07), and if in either case the Company pays all other sums payable 
hereunder by the Company, then this Indenture shall, subject to Section 
8.01(c), cease to be of further effect.  The Trustee shall acknowledge 
satisfaction and discharge of this Indenture on demand of the Company 
accompanied by an Officers' Certificate and an Opinion of Counsel that the 
conditions precedent to satisfaction and discharge have been satisfied 
(provided that the Opinion of Counsel will not be required to cover 
compliance with any financial tests or financial covenants) and at the cost 
and expense of the Company.

    (b)  Subject to Sections 8.01(c) and 8.02, the Company at any time may 
terminate (i) all of its obligations under the Securities and this Indenture 
("legal defeasance option") or (ii) its obligations under Sections 4.02, 
4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11 and 5.01 and the 
operation of Sections 6.01(3), 6.01(4), 6.01(5), 6.01(6) (with respect to 
Subsidiaries of the Company only), 6.01(7) (with respect to Subsidiaries of 
the Company only) and 6.01(8) ("covenant defeasance option").  The Company 
may exercise its legal defeasance option notwithstanding its prior exercise 
of its covenant defeasance option. 

    If the Company exercises its legal defeasance option, payment of the 
Securities may not be accelerated because of an Event of Default.  If the 
Company exercises its covenant defeasance option, payment of the Securities 
may not be accelerated because of an Event of Default specified in Section 
6.01(3), 6.01(4), 6.01(5), 6.01(6) (with respect to Subsidiaries of the 
Company only), 6.01(7) (with respect to Subsidiaries of the Company only) or 
6.01(8).

    Upon satisfaction of the conditions set forth herein and upon request of 
the Company, the Trustee shall acknowledge in writing the discharge of those 
obligations that the Company terminates.

    (c)  Notwithstanding clauses (a) and (b) above, the Company's obligations 
in Sections 2.03, 2.04, 2.05, 



                                                                             66

2.06, 2.07, 2.08, 7.07, 7.08 and in this Article 8 shall survive until the 
Securities have been paid in full.  Thereafter, the Company's obligations in 
Sections 7.07, 8.04 and 8.05 shall survive.

    SECTION 8.02.  Conditions to Defeasance.  The Company may exercise its 
legal defeasance option or its covenant defeasance option only if:

         (1) the Company irrevocably deposits in trust with the Trustee, for 
     the benefit of the Holders, cash in U.S. Dollars, U.S. Government 
     Obligations, or a combination thereof, in such amounts as shall be 
     sufficient, in the opinion of a nationally recognized firm of 
     independent public accountants, to pay the principal of and interest on 
     the outstanding Securities on the stated maturity of such principal or 
     installment of interest or upon redemption; 

         (2) the Company shall have delivered to the Trustee an Opinion of 
     Counsel stating that the Holders of the outstanding Securities will not 
     recognize income, gain or loss for Federal income tax purposes as a 
     result of such defeasance and shall be subject to Federal income tax on 
     the same amounts, in the same manner and at the same times as would have 
     been the case if such defeasance had not occurred, which such opinion, 
     in the case of legal defeasance, shall also state that (A) the Company 
     has received from, or there has been published by, the Internal Revenue 
     Service a ruling to such effect or (B) since the Closing Date there has 
     been a change in the applicable Federal income tax laws or regulations 
     to such effect or (C) there exists controlling precedent to such effect; 

         (3) no Default or Event of Default shall have occurred and be 
     continuing on the date of such deposit; 

         (4) such defeasance shall not result in a breach or violation of or 
     constitute a default under any material agreement or instrument to which 
     the Company is a party or by which it is bound; and

         (5) the Company shall have delivered to the Trustee an Officers' 
     Certificate and an Opinion of Counsel, each stating that all conditions 
     precedent to such defeasance have been satisfied.



                                                                             67


    Before or after a deposit, the Company may make arrangements satisfactory 
to the Trustee for the redemption of Securities at a future date in 
accordance with Article 3.

    SECTION 8.03.  Application of Trust Money.  The Trustee shall hold in 
trust money or U.S. Government Obligations deposited with it pursuant to this 
Article 8.  It shall apply the deposited money and the money from U.S. 
Government Obligations through the Paying Agent and in accordance with this 
Indenture to the payment of principal of and interest on the Securities.  
Money and securities so held in trust are not subject to Article 10.

    SECTION 8.04.  Repayment to Company.  The Trustee and the Paying Agent 
shall promptly turn over to the Company upon request any excess money or 
securities held by them at any time.

    Subject to any applicable abandoned property law, the Trustee and the 
Paying Agent shall pay to the Company upon written request any money held by 
them for the payment of principal or interest that remains unclaimed for two 
years, and, thereafter, Securityholders entitled to the money must look to 
the Company for payment as general creditors.

    SECTION 8.05.  Indemnity for Government Obligations.  The Company shall 
pay and shall indemnify the Trustee against any tax, fee or other charge 
imposed on or assessed against deposited U.S. Government Obligations or the 
principal and interest received on such U.S. Government Obligations.

    SECTION 8.06.  Reinstatement.  If the Trustee or Paying Agent is unable 
to apply any money or U.S. Government Obligations in accordance with this 
Article 8 by reason of any legal proceeding or by reason of any order or 
judgment of any court or governmental authority enjoining, restraining or 
otherwise prohibiting such application, the Company's obligations under this 
Indenture and the Securities shall be revived and reinstated as though no 
deposit had occurred pursuant to this Article 8 until such time as the 
Trustee or Paying Agent is permitted to apply all such money or U.S. 
Government Obligations in accordance with this Article 8;  provided, however, 
that, if the Company has made any payment of interest on or principal of any 
Securities because of the reinstatement of its obligations, the Company shall 
be subrogated to the rights of the Holders of such Securities to receive such 
payment from the money or U.S. Government Obligations held by the Trustee or

                                     Amendments

    SECTION 9.01.  Without Consent of Holders.  The Company and the Trustee 
may amend or supplement this Indenture or the Securities without notice to or 
consent of any Securityholder:

         (1) to cure any ambiguity, defect or inconsistency;

         (2) to comply with Article 5;

         (3) to provide for certificated or uncertificated Securities 
     (provided that the uncertificated Securities are issued in registered 
     form for purposes of Section 163(f) of the Code, or in a manner such 
     that the uncertificated Securities are described in Section 163(f)(2)(B) 
     of the Code);

         (4) to make any change in Article 10 that would limit or terminate 
     the benefits available to any holder of Senior Indebtedness (or 
     Representatives therefor) under Article 10;

         (5) to add guarantees with respect to the Securities or to secure 
     the Securities;  

         (6) to add to the covenants of the Company for the benefit of the 
     Holders or to surrender any right or power herein conferred upon the 
     Company;

         (7) to comply with any requirements of the SEC in connection with 
     qualifying, or maintaining the qualification of, this Indenture under 
     the TIA;

         (8) to make any change that does not adversely affect the rights of 
     any Securityholder; or 

         (9) to provide for the issuance of the Exchange Securities or 
     Private Exchange Securities, which shall have terms substantially 
     identical in all material respects to the Initial Securities (except 
     that the transfer restrictions contained in the Initial Securities shall 
     be modified or eliminated, as appropriate), and which shall be treated, 
     together with any outstanding Initial Securities, as a single issue of 
     securities.



                                                                             69


    An amendment under this Section may not make any change that adversely 
affects the rights under Article 10 of any holder of Senior Indebtedness then 
outstanding unless the holders of such Senior Indebtedness (or any group or 
representative thereof authorized to give a consent) consent to such change.

    After an amendment under this Section becomes effective, the Company 
shall mail to Securityholders a notice briefly describing such amendment.  
The failure to give such notice to all Securityholders, or any defect 
therein, shall not impair or affect the validity of an amendment under this 
Section.

    SECTION 9.02.  With Consent of Holders.  The Company and the Trustee may 
amend or supplement this Indenture or the Securities without notice to any 
Securityholder but with the written consent of the Holders of at least a 
majority in principal amount of the Securities then outstanding (including 
consents obtained in connection with a tender offer or exchange for the 
Securities).  However, without the consent of each Securityholder affected, 
an amendment may not:

         (1) reduce the percentage of the principal amount of the Securities 
    whose Holders must consent to an amendment, supplement or waiver;

         (2) change the stated maturity or the time or currency of payment of 
    the principal of or any interest on, or reduce the rate of interest on or 
    principal of any Security or alter the redemption provisions with respect 
    thereto; 

         (3) make any change in Article 10 of this Indenture that adversely 
    affects the rights of any Holder under Article 10 of this Indenture; 

         (4) impair the right of any Holder to institute suit for the 
    enforcement of any payment on or with respect to such Holder's 
    Securities; 

         (5) waive a default in the payment of the principal of or interest 
    on any Security;

         (6) make any change to the provisions of this Indenture relating to 
    the Excess Proceeds Offer;

         (7) make any change to Section 9.07 of this Indenture; or



                                                                             70


         (8) make any change in Section 6.04 or 6.07 or the second sentence 
    of this Section 9.02.

    It shall not be necessary for the consent of the Holders under this 
Section to approve the particular form of any proposed amendment, but it 
shall be sufficient if such consent approves the substance thereof.

    An amendment under this Section 9.02 may not make any change that 
adversely affects the rights under Article 10 of any holder of Senior 
Indebtedness then outstanding unless the holders of such Senior Indebtedness 
(or any group or representative thereof authorized to give a consent) consent 
to such change.

    After an amendment under this Section becomes effective, the Company 
shall mail to Securityholders a notice briefly describing such amendment.  
The failure to give such notice to all Securityholders, or any defect 
therein, shall not impair or affect the validity of an amendment under this 
Section.

    SECTION 9.03.  Compliance with Trust Indenture Act.  Every amendment to 
this Indenture or the Securities shall comply with the TIA as then in effect.

    SECTION 9.04.  Revocation and Effect of Consents and Waivers.  A consent 
to an amendment or a waiver by a Holder of a Security shall bind the Holder 
and every subsequent Holder of that Security or portion of the Security that 
evidences the same debt as the consenting Holder's Security, even if notation 
of the consent or waiver is not made on the Security.  However, any such 
Holder or subsequent Holder may revoke the consent or waiver as to such 
Holder's Security or portion of the Security if the Trustee receives the 
notice of revocation before the date the amendment or waiver becomes 
effective.  After an amendment or waiver becomes effective, it shall bind 
every Securityholder. An amendment or waiver becomes effective once both (i) 
the requisite number of consents have been received by the Company or the 
Trustee and (ii) such amendment or waiver has been executed by the Company 
and the Trustee.

    The Company may, but shall not be obligated to, fix a record date for the 
purpose of determining the Securityholders entitled to give their consent or 
take any other action described above or required or permitted to be taken 
pursuant to this Indenture.  If a record date is fixed, then notwithstanding 
the immediately preceding 



                                                                             71

paragraph, those Persons who were Securityholders at such record date (or 
their duly designated proxies), and only those Persons, shall be entitled to 
give such consent or to revoke any consent previously given or to take any 
such action, whether or not such Persons continue to be Holders after such 
record date.  No such consent shall be valid or effective for more than 120 
days after such record date.

    SECTION 9.05.  Notation on or Exchange of Securities.  If an amendment 
changes the terms of a Security, the Trustee may require the Holder of the 
Security to deliver it to the Trustee.  The Trustee may place an appropriate 
notation on the Security regarding the changed terms and return it to the 
Holder.  Alternatively, if the Company or the Trustee so determines, the 
Company in exchange for the Security shall issue and the Trustee shall 
authenticate a new Security that reflects the changed terms.  Failure to make 
the appropriate notation or to issue a new Security shall not affect the 
validity of such amendment.

    SECTION 9.06.  Trustee To Sign Amendments.  The Trustee shall sign any 
amendment authorized pursuant to this Article 9 if the amendment does not 
adversely affect the rights, duties, liabilities or immunities of the 
Trustee. If it does, the Trustee may but need not sign it.  In signing such 
amendment the Trustee shall be entitled to receive indemnity reasonably 
satisfactory to it and to receive, and (subject to Section 7.01) shall be 
fully protected in relying upon, an Officers' Certificate and an Opinion of 
Counsel stating that such amendment is authorized or permitted by this 
Indenture and that such amendment is the legal, valid and binding obligation 
of the Company enforceable against it in accordance with its terms, subject 
to customary exceptions, and complies with the provisions hereof (including 
Section 9.03).

    SECTION 9.07.  Payment for Consent.  Neither the Company nor any of its 
Subsidiaries shall, directly or indirectly, pay or cause to be paid any 
consideration, whether by way of interest, fee or otherwise, to any Holder 
for or as an inducement to obtaining any consent, waiver or amendment of, or 
direction in respect of, any of the terms or provisions of this Indenture or 
the Securities, unless such consideration is offered or agreed to be paid, 
and paid, to all Holders which so consent, waive, agree or direct in the time 
frame set forth in solicitation documents relating to such consent, waiver, 
agreement or direction.



                                                                             72


                                     ARTICLE 10
                                          
                                   Subordination

    SECTION 10.01.  Agreement To Subordinate.  The Company agrees, and each 
Securityholder by accepting a Security agrees, that the Indebtedness 
evidenced by the Securities is subordinated in right of payment, to the 
extent and in the manner provided in this Article 10, to the prior payment in 
full of all Senior Indebtedness of the Company and that the subordination is 
for the benefit of and enforceable by the holders of such Senior 
Indebtedness.  The Securities shall in all respects rank pari passu with all 
other Senior Subordinated Indebtedness of the Company and only Indebtedness 
of the Company that is Senior Indebtedness of the Company shall rank senior 
to the Securities in accordance with the provisions set forth herein.  For 
purposes of this Article 10, the Indebtedness evidenced by the Securities 
shall be deemed to include the liquidated damages payable pursuant to the 
provisions set forth in the Registration Agreement.  All provisions of this 
Article 10 shall be subject to Section 10.12.

    SECTION 10.02.  Liquidation, Dissolution, Bankruptcy.  Upon any payment 
or distribution of the assets of the Company to creditors upon a total or 
partial liquidation or a total or partial dissolution of the Company or in a 
winding up, bankruptcy, reorganization, assignment for the benefit of 
creditors, marshalling of assets and liabilities, insolvency, receivership or 
similar proceeding relating to the Company or its property:

         (1) holders of Senior Indebtedness of the Company shall be entitled 
     to receive payment in full of such Senior Indebtedness before 
     Securityholders shall be entitled to receive any direct or indirect 
     payment on account of principal of or interest on the Securities; and

         (2) until the Senior Indebtedness of the Company is paid in full, 
     any payment or distribution to which Securityholders would be entitled 
     but for this Article 10 shall be made to holders of such Senior 
     Indebtedness as their interests may appear, except that Securityholders 
     may receive shares of stock and any debt securities that are 
     subordinated to such Senior Indebtedness to at least the same extent as 
     the Securities.



                                                                             73


    SECTION 10.03.  Default on Senior Indebtedness.  The Company may not pay 
the principal of or interest on the Securities or make any deposit pursuant 
to Article 8 and may not repurchase, redeem or otherwise retire any 
Securities (collectively, "pay the Securities") if (i) any Specified Senior 
Indebtedness of the Company is not paid when due or (ii) any other default on 
Specified Senior Indebtedness occurs which results in the maturity of such 
Specified Senior Indebtedness being accelerated in accordance with its terms 
unless, in either case, (x) the default has been cured or waived and any such 
acceleration has been rescinded or (y) such Specified Senior Indebtedness has 
been paid in full; provided, however, that the Company may pay the Securities 
without regard to the foregoing if the Company and the Trustee receive 
written notice approving such payment from the Representative of such 
Specified Senior Indebtedness with respect to which either of the events in 
clause (i) or (ii) of this sentence has occurred and is continuing.  During 
the continuance of any default (other than a default described in clause (i) 
or (ii) of the preceding sentence) with respect to any Specified Senior 
Indebtedness pursuant to which the maturity thereof may be accelerated 
immediately without further notice (except such notice as may be required to 
effect such acceleration) or the expiration of any applicable grace periods, 
the Company may not pay the Securities for a period (a "Payment Blockage 
Period") commencing upon the receipt by the Trustee (with a copy to the 
Company) of written notice (a "Blockage Notice") of such default from the 
Representative of such Specified Senior Indebtedness specifying an election 
to effect a Payment Blockage Period and ending 179 days thereafter (or 
earlier if such Payment Blockage Period is terminated (i) by written notice 
to the Trustee and the Company from the Person or Persons who gave such 
Blockage Notice, (ii) by repayment in full of such Specified Senior 
Indebtedness or (iii) because the default giving rise to such Blockage Notice 
is no longer continuing). Notwithstanding the provisions described in the 
immediately preceding sentence (but subject to the provisions contained in 
the first sentence of this Section), unless the holders of such Specified 
Senior Indebtedness or the Representative of such holders shall have 
accelerated the maturity of such Specified Senior Indebtedness, the Company 
may resume payments on the Securities after such Payment Blockage Period.  
Not more than one Blockage Notice may be given in any consecutive 360-day 
period, irrespective of the number of defaults that may exist or occur with 
respect to Specified Senior Indebtedness during such period; provided, 
however, that if any Blockage Notice within such 360-day period is given by 
or on behalf of any holders of Specified 



                                                                             74

Senior Indebtedness other than the Bank Indebtedness, the Representative of 
the Bank Indebtedness may give another Blockage Notice within such period; 
provided further, however, that in no event may the total number of days 
during which any Payment Blockage Period or Periods is in effect exceed 179 
days in the aggregate during any 360 consecutive day period.  For purposes of 
this Section, no default or event of default that existed or was continuing 
on the date of the commencement of any Payment Blockage Period with respect 
to the Specified Senior Indebtedness initiating such Payment Blockage Period 
shall be, or be made, the basis of the commencement of a subsequent Payment 
Blockage Period by the Representative of such Specified Senior Indebtedness, 
whether or not within a period of 360 consecutive days, unless such default 
or event of default shall have been cured or waived for a period of not less 
than 90 consecutive days.

    SECTION 10.04.  Acceleration of Payment of Securities.  If payment of the 
Securities is accelerated because of an Event of Default, the Company or the 
Trustee shall promptly notify the holders of the Specified Senior 
Indebtedness (or their Representative) of the acceleration.  If any Specified 
Senior Indebtedness is outstanding, the Company may not pay the Securities 
until five Business Days after such holders or the Representative of the 
Specified Senior Indebtedness receive notice of such acceleration and, 
thereafter, may pay the Securities only if this Article 10 otherwise permits 
payment at that time.

    SECTION 10.05.  When Distribution Must Be Paid Over.  If a distribution 
is made to Securityholders that because of this Article 10 should not have 
been made to them, the Securityholders who receive the distribution shall 
hold it in trust for holders of Senior Indebtedness of the Company and pay it 
over to them as their interests may appear.

    SECTION 10.06.  Subrogation.  After all Senior Indebtedness of the 
Company is paid in full and until the Securities are paid in full, 
Securityholders shall be subrogated to the rights of holders of such Senior 
Indebtedness to receive distributions applicable to Senior Indebtedness.  A 
distribution made under this Article 10 to holders of such Senior 
Indebtedness which otherwise would have been made to Securityholders is not, 
as between the Company and Securityholders, a payment by the Company on such 
Senior Indebtedness.



                                                                             75


    SECTION 10.07.  Relative Rights.  This Article 10 defines the relative 
rights of Securityholders and holders of Senior Indebtedness of the Company. 
Nothing in this Indenture shall:

         (1) impair, as between the Company and Securityholders, the 
     obligation of the Company, which is absolute and unconditional, to pay 
     principal of and interest on and liquidated damages in respect of, the 
     Securities in accordance with their terms; or

         (2) prevent the Trustee or any Securityholder from exercising its 
     available remedies upon an Event of  Default, subject to the rights of 
     holders of Senior Indebtedness of the Company to receive distributions 
     otherwise payable to Securityholders.

    SECTION 10.08.  Subordination May Not Be Impaired by Company.  No right 
of any holder of Senior Indebtedness of the Company to enforce the 
subordination of the Indebtedness evidenced by the Securities shall be 
impaired by any act or failure to act by the Company or by its failure to 
comply with this Indenture.

    SECTION 10.09.  Rights of Trustee and Paying Agent.  Notwithstanding 
Section 10.03, the Trustee or Paying Agent may continue to make payments on 
the Securities and shall not be charged with knowledge of the existence of 
facts that would prohibit the making of any such payments unless, not less 
than two Business Days prior to the date of such payment, a Trust Officer of 
the Trustee receives notice satisfactory to it that payments may not be made 
under this Article 10.  The Company, the Registrar or co-registrar, the 
Paying Agent, a Representative or a holder of Specified Senior Indebtedness 
of the Company may give the notice; provided, however, that, if an issue of 
Specified Senior Indebtedness of the Company has a Representative, only the 
Representative may give the notice.

    The Trustee in its individual or any other capacity may hold Senior 
Indebtedness of the Company with the same rights it would have if it were not 
Trustee.  The Registrar and co-registrar and the Paying Agent may do the same 
with like rights.  The Trustee shall be entitled to all the rights set forth 
in this Article 10 with respect to any Senior Indebtedness of the Company 
which may at any time be held by it, to the same extent as any other holder 
of such Senior Indebtedness; and nothing in Article 7 shall deprive the 
Trustee of any of its rights as such holder.  Nothing in 



                                                                             76

this Article 10 shall apply to claims of, or payments to, the Trustee under 
or pursuant to Section 7.07.

    SECTION 10.10.  Distribution or Notice to Representative.  Whenever a 
distribution is to be made or a notice given to holders of Specified Senior 
Indebtedness of the Company, the distribution may be made and the notice 
given to their Representative (if any).

    SECTION 10.11.  Article 10 Not To Prevent Events of Default or Limit 
Right To Accelerate.  The failure to make a payment pursuant to the 
Securities by reason of any provision in this Article 10 shall not be 
construed as preventing the occurrence of a Default.  Nothing in this Article 
10 shall have any effect on the right of the Securityholders or the Trustee 
to accelerate the maturity of the Securities.

    SECTION 10.12.  Trust Moneys Not Subordinated.  Notwithstanding anything 
contained herein to the contrary, payments from money or the proceeds of U.S. 
Government Obligations held in trust under Article 8 by the Trustee for the 
payment of principal of and interest on the Securities shall not be 
subordinated to the prior payment of any Senior Indebtedness of the Company 
or subject to the restrictions set forth in this Article 10, and none of the 
Securityholders shall be obligated to pay over any such amount to the Company 
or any holder of Senior Indebtedness of the Company or any other creditor of 
the Company.

    SECTION 10.13.  Trustee Entitled To Rely.  Upon any payment or 
distribution pursuant to this Article 10, the Trustee and the Securityholders 
shall be entitled to rely (i) upon any order or decree of a court of 
competent jurisdiction in which any proceedings of the nature referred to in 
Section 10.02 are pending, (ii) upon a certificate of the liquidating trustee 
or agent or other Person making such payment or distribution to the Trustee 
or to the Securityholders or (iii) upon the Representatives for the holders 
of Senior Indebtedness of the Company for the purpose of ascertaining the 
Persons entitled to participate in such payment or distribution, the holders 
of such Senior Indebtedness and other Indebtedness of the Company, the amount 
thereof or payable thereon, the amount or amounts paid or distributed thereon 
and all other facts pertinent thereto or to this Article 10.  In the event 
that the Trustee determines, in good faith, that evidence is required with 
respect to the right of any Person as a holder of Senior Indebtedness of the 
Company to participate in any payment or distribution pursuant to this 
Article 10, the 



                                                                             77

Trustee may request such Person to furnish evidence to the reasonable 
satisfaction of the Trustee as to the amount of such Senior Indebtedness held 
by such Person, the extent to which such Person is entitled to participate in 
such payment or distribution and other facts pertinent to the rights of such 
Person under this Article 10, and, if such evidence is not furnished, the 
Trustee may defer any payment to such Person pending judicial determination 
as to the right of such Person to receive such payment.  The provisions of 
Sections 7.01 and 7.02 shall be applicable to all actions or omissions of 
actions by the Trustee pursuant to this Article 10.

    SECTION 10.14.  Trustee To Effectuate Subordination.  Each Securityholder 
by accepting a Security authorizes and directs the Trustee on his behalf to 
take such action as may be necessary or appropriate to acknowledge or 
effectuate the subordination between the Securityholders and the holders of 
Senior Indebtedness of the Company as provided in this Article 10 and 
appoints the Trustee as attorney-in-fact for any and all such purposes.

    SECTION 10.15.  Trustee Not Fiduciary for Holders of Senior Indebtedness. 
 The Trustee shall not be deemed to owe any fiduciary duty to the holders of 
Senior Indebtedness of the Company and shall not be liable to any such 
holders if it shall mistakenly pay over or distribute to Securityholders or 
the Company or any other Person, money or assets to which any holders of 
Senior Indebtedness of the Company shall be entitled by virtue of this 
Article 10 or otherwise.

    SECTION 10.16.  Reliance by Holders of Senior Indebtedness on 
Subordination Provisions.  Each Securityholder by accepting a Security 
acknowledges and agrees that the foregoing subordination provisions are, and 
are intended to be, an inducement and a consideration to each holder of any 
Senior Indebtedness of the Company, whether such Senior Indebtedness was 
created or acquired before or after the issuance of the Securities, to 
acquire and continue to hold, or to continue to hold, such Senior 
Indebtedness and such holder of such Senior Indebtedness shall be deemed 
conclusively to have relied on such subordination provisions in acquiring and 
continuing to hold, or in continuing to hold, such Senior Indebtedness.

    SECTION 10.17.  Trustee's Compensation Not Prejudiced.  Nothing in this 
Article shall apply to amounts due to the Trustee pursuant to other sections 
of this Indenture.



                                                                             78

                                   Miscellaneous

    SECTION 11.01.  Trust Indenture Act Controls.  If any provision of this 
Indenture limits, qualifies or conflicts with another provision which is 
required to be included in this Indenture by the TIA, the required provision 
shall control.

    SECTION 11.02.  Notices.  Any notice or communication shall be in writing 
and delivered in person or mailed by first-class mail addressed as follows:

    The Company or the Trustee by notice to the other may designate

Person directly or indirectly controlling or controlled by or under direct or 
indirect common control with the Company shall be disregarded and deemed not 
to be outstanding, except that, for the purpose of determining whether the 
Trustee shall be protected in relying on any such direction, waiver or 
consent, only Securities which the Trustee knows are so owned shall be so 
disregarded. Subject to the foregoing, only Securities outstanding at the 
time shall be considered in any such determination.

    SECTION 11.07.  Rules by Trustee, Paying Agent and Registrar.  The

Indenture and the Securities shall bind its successors.  All agreements of

Company, the Trustee and any agent of the Company or the Trustee as the 
absolute owner of such Global Security for all purposes whatsoever.  
Notwithstanding the foregoing, nothing herein shall prevent the Company, the 
Trustee or any agent of the Company or the Trustee from giving effect to any 
written certification, proxy or other authorization furnished by the 
Depositary or impair, as between the Depositary and its Agent Members, the 
operation of customary practices of such

Initial Securities exchanged pursuant thereto.  Such order shall specify the 
amount of the Securities to be authenticated, the date on which the original 
issue of Securities is to be authenticated and whether the Securities are to

The aggregate principal amount of Securities outstanding at any time may not 
exceed $625,000,000 except as provided in Section 2.07 of this Indenture.

         (x)  to register the transfer of such Definitive Securities; or

         (y)  to exchange such Definitive Securities for an equal principal   
     amount of Definitive Securities of other authorized denominations,

          Registrar by a Holder for registration in the name of such Holder, 
          without transfer, a certification from such Holder to that effect 
          (in the form set forth on the reverse side of the Initial 
          Security); or

              (B)  if such Definitive Securities are being transferred to the 
          Company, a certification to that effect (in the form set forth on 
          the reverse side of the Initial Security); or

              (C)  if such Definitive Securities are being transferred 
          pursuant to an exemption from registration in accordance with Rule 
          144 under the Securities Act or in reliance upon another exemption 
          from the registration requirements of the Securities Act, (i) a 
          certification to that effect (in the form set forth on the reverse 
          side of the Initial Security) and (ii) if the Company so requests, 
          an opinion of counsel or other evidence reasonably satisfactory to 
          it as to the compliance with the restrictions set forth in the 
          legend set forth in Section 2.3(d)(i).

    (b)  Restrictions on Transfer of a Definitive Security for a Beneficial 
Interest in a Global Security.  A Definitive Security may not be exchanged 
for a beneficial interest in a Global Security except upon satisfaction of 
the requirements set forth below.  Upon receipt by the Trustee of a 
Definitive Security, duly endorsed or accompanied by a written instrument of 
transfer in form reasonably satisfactory to the Company and the Registrar, 
together with:

         (i)  certification (in the form set forth on the reverse side of the 
     Initial Security) that such Definitive Security is being transferred (A) 
     to a QIB in accordance with Rule 144A, (B) to an IAI that has furnished 
     to the Trustee a signed letter substantially in the form of Exhibit C or 
     (C) outside the United States in an offshore transaction within the 
     meaning of Regulation S and in compliance with Rule 904 under the 
     Securities Act; and

         (ii)  written instructions directing the Trustee to make, or to 
     direct the Securities Custodian to make, an 



                                                                              7

     adjustment on its books and records with respect to such Global Security 
     to reflect an increase in the aggregate principal amount of the 
     Securities represented by the Global Security, such instructions to 
     contain information regarding the Depositary account to be credited with 
     such increase,

then the Trustee shall cancel such Definitive Security and cause, or direct 
the Securities Custodian to cause, in accordance with the standing 
instructions and procedures existing between the Depositary and the 
Securities Custodian, the aggregate principal amount of Securities 
represented by the Global Security to be increased by the aggregate principal 
amount of the Definitive Security to be exchanged and shall credit or cause 
to be credited to the account of the Person specified in such instructions a 
beneficial interest in the Global Security equal to the principal amount of 
the Definitive Security so canceled.  If no Global Securities are then 
outstanding and the Global Security has not been previously exchanged for 
certificated securities pursuant to Section 2.4, the Company shall issue and 
the Trustee shall authenticate, upon written order of the Company in the form 
of an Officers' Certificate, a new Global Security in the appropriate 
principal amount.

    (c)  Transfer and Exchange of Global Securities.  (i)  The transfer and 
exchange of Global Securities or beneficial interests therein shall be 
effected through the Depositary, in accordance with this Indenture (including 
applicable restrictions on transfer set forth herein, if any) and the 
procedures of the Depositary therefor.  A transferor of a beneficial interest 
in a Global Security shall deliver a written order given in accordance with 
the Depositary's procedures containing information regarding the participant 
account of the Depositary to be credited with a beneficial interest in such 
Global Security or another Global Security and such account shall be credited 
in accordance with such order with a beneficial interest in the applicable 
Global Security and the account of the Person making the transfer shall be 
debited by an amount equal to the beneficial interest in the Global Security 
being transferred.  Transfers of beneficial interests in the Rule 144A Global 
Security or the IAI Global Security to a transferee who takes delivery of 
such interest through the Regulation S Global Security will be made only upon 
receipt by the Trustee of a certification from the transferor to the effect 
that such transfer is being made in accordance with Regulation S or Rule 144 
under the Securities Act, if available.  In the case of a transfer of a 
beneficial interest in either the Regulation S Global Security or the Rule 
144A Global Security for an interest in the IAI Global 



                                                                              8

Security, the transferee must furnish a signed letter substantially in the 
form of Exhibit C to the Trustee.

         (ii)  If the proposed transfer is a transfer of a beneficial 
     interest in one Global Security to a beneficial interest in another 
     Global Security, the Registrar shall reflect on its books and records 
     the date and an increase in the principal amount of the Global Security 
     to which such interest is being transferred in an amount equal to the 
     principal amount of the interest to be so transferred, and the Registrar 
     shall reflect on its books and records the date and a corresponding 
     decrease in the principal amount of Global Security from which such 
     interest is being transferred.

     (iii)  Notwithstanding any other provisions of this Appendix (other than 
     the provisions set forth in Section 2.4), a Global Security may not be 
     transferred as a whole except by the Depositary to a nominee of the 
     Depositary or by a nominee of the Depositary to the Depositary or 
     another nominee of the Depositary or by the Depositary or any such 
     nominee to a successor Depositary or a nominee of such successor 
     Depositary.

     (iv)  In the event that a Global Security is exchanged for Definitive 
     Securities pursuant to Section 2.4 prior to the consummation of the 
     Registered Exchange Offer or the effectiveness of the Shelf Registration 
     Statement with respect to such Securities, such Securities may be 
     exchanged only in accordance with such procedures as are substantially 
     consistent with the provisions of this Section 2.3 (including the 
     certification requirements set forth on the reverse of the Initial 
     Securities intended to ensure that such transfers comply with Rule 144A, 
     Regulation S or such other applicable exemption from registration under 
     the Securities Act, as the case may be) and such other procedures as may 
     from time to time be adopted by the Company.

    (d)  Restrictions on Transfer of Regulation S Global Security.   (i) 
Prior to the expiration of the Restricted Period, interests in the Regulation 
S Global Security may only be held through Euroclear or Cedel.  During the 
Restricted Period, beneficial ownership interests in the Regulation S Global 
Security may only be sold, pledged or transferred through Euroclear or Cedel 
in accordance with the Applicable Procedures and only (A) to the Company, (B) 
so long as such security is eligible for resale pursuant to Rule 144A, to a 
person whom the selling holder reasonably believes is a QIB 



                                                                              9

that purchases for its own account or for the account of a QIB to whom notice

transfer of a beneficial interest in the Regulation S Global Security for an 
interest in the IAI Global Security, the transferee must furnish a signed 
letter substantially in the form of Exhibit C to the Trustee.

         (ii)  Upon the expiration of the Restricted Period, beneficial 
     ownership interests in the Regulation S Global Security will be

          (ii)  Upon any sale or transfer of a Transfer Restricted Security that
     is a Definitive Security, the Registrar shall permit the Holder thereof to
     exchange such Transfer Restricted Security for a Definitive Security that
     does not bear the legends set forth above and rescind any restriction on
     the transfer of such Transfer Restricted Security if the Holder certifies
     in writing to the Registrar that its request for such exchange was made in
     reliance on Rule 144 (such certification to be in the form set forth on the
     reverse of the Initial Security).

          (iii)  After a transfer of any Initial Securities or Private Exchange
     Securities during the period of the effectiveness of a Shelf Registration
     Statement with respect to such Initial Securities or Private Exchange
     Securities, as the case may be, all requirements pertaining to the
     Restricted Securities Legend on such Initial Securities or such Private
     Exchange Securities will cease to apply and the requirements that any such
     Initial Securities or such Private Exchange Securities be issued in global
     form will continue to apply.

          (iv)  Upon the consummation of a Registered Exchange Offer with

          (f)  Cancelation or Adjustment of Global Security.  At such time as 
all beneficial interests in a Global Security have either been exchanged for 
Definitive Securities, transferred, redeemed, repurchased or canceled, such 
Global Security shall be returned by the Depositary to the Trustee for 
cancelation or retained and canceled by the Trustee.  At any time prior to 
such cancelation, if any beneficial interest in a Global Security is 
exchanged for Definitive Securities, transferred in exchange for an interest 
in another Global Security, redeemed, repurchased or canceled, the principal 
amount of Securities represented by such Global Security shall be reduced and 
an adjustment shall be made on the books and records of the Trustee (if it is 
then the Securities Custodian for such Global Security) with respect to such 
Global Security, by the Trustee or the Securities Custodian, to reflect such 
reduction.

     shall execute and the Trustee shall authenticate, Definitive Securities and
     Global Securities at the Registrar's request.

          (ii) No service charge shall be made for any registration of transfer
     or exchange, but the Company may require payment of a sum sufficient to
     cover any transfer tax, assessments, or similar governmental charge payable
     in connection therewith (other than any such transfer taxes, assessments or
     similar governmental charge payable upon exchange or transfer pursuant to
     Section 3.06, 4.06, 4.08 and 9.05 of the Indenture).

          (iii)  Prior to the due presentation for registration of transfer of
     any Security, the Company, the Trustee, the Paying Agent or the Registrar
     may deem and treat the Person in whose name a Security is registered as the



                                                                             13

     absolute owner of such Security for the purpose of receiving payment of
     principal of and interest on such Security and for all other purposes
     whatsoever, whether or not such Security is overdue, and none of the
     Company, the Trustee, the Paying Agent or the Registrar  shall be affected
     by notice to the contrary.

          (iv)  All Securities issued upon any transfer or exchange pursuant to
     the terms of this Indenture shall evidence the same debt and shall be
     entitled to the same benefits under this Indenture as the Securities
     surrendered upon such transfer or exchange.

          (h)  No Obligation of the Trustee.

          (i)  The Trustee shall have no responsibility or obligation to any
     beneficial owner of a Global Security, a member of, or a participant in the
     Depositary or any other Person with respect to the accuracy of the records
     of the Depositary or its nominee or of any participant or member thereof,
     with respect to any ownership interest in the Securities or with respect to
     the delivery to any participant, member, beneficial owner or other Person
     (other than the Depositary) of any notice (including any notice of
     redemption or repurchase) or the payment of any amount, under or with
     respect to such Securities.  All notices and communications to be given to
     the Holders and all payments to be made to Holders under the Securities
     shall be given or made only to the registered Holders (which shall be the
     Depositary or its nominee in the case of a Global Security).  The rights of
     beneficial owners in any Global Security shall be exercised only through
     the Depositary subject to the applicable rules and procedures of the
     Depositary.  The Trustee may rely and shall be fully protected in relying
     upon information furnished by the Depositary with respect to its members,
     participants and any beneficial owners.

          (ii)  The Trustee shall have no obligation or duty to monitor,
     determine or inquire as to compliance with any restrictions on transfer
     imposed under this Indenture or under applicable law with respect to any
     transfer of any interest in any Security (including any transfers between
     or among Depositary participants, members or beneficial owners in any
     Global Security) other than to require delivery of such certificates and
     other documentation or evidence as are expressly required by, and to do so
     if and when expressly required by, the terms of this Indenture, and to
     examine the same to determine

     substantial compliance as to form with the express requirements hereof.

          Capitalized terms used but not defined herein shall have the 
meanings given to such terms in the Indenture (as defined).

1.   Interest

          (a) MAGELLAN HEALTH SERVICES, INC., a Delaware corporation (such 
corporation, and its successors and assigns under the Indenture hereinafter 
referred to, being herein called the "Company"), promises to pay interest on 
the principal amount of this Security at the rate per annum shown above.  The 
Company will pay interest semiannually on February 15 and August 15 of each 
year, commencing on August 15, 1998.  Interest on the Securities will accrue 
from the most recent date to which interest has been paid or, if no interest 
has been paid, from February 12, 1998.  Interest will be computed on the 
basis of a 360-day year of twelve 30-day months.  The Company shall pay 
interest on overdue principal at the rate borne by the Securities plus 1% per 
annum, and it shall pay interest on overdue installments of interest at the 
same rate to the extent lawful.

          (b) Liquidated Damages.  The Holder of this Security is entitled to 
the benefits of the Exchange and Registration Rights Agreement, dated as of 
February 12, 1998, between the Company and the Initial Purchaser named 
therein (the "Registration Agreement").  Capitalized terms used in this 
paragraph (b) but not defined herein have the meanings assigned to them in 
the Registration Agreement.  If (i) the Shelf Registration Statement or 
Exchange Offer Registration Statement, as applicable under the Registration 
Agreement is not filed with the SEC on or prior to 60 days after the Issue 
Date, (ii) the Exchange Offer Registration Statement or the Shelf 
Registration Statement, as the case may be, is not declared effective within 
150 days after the Issue Date, (iii) the Registered Exchange Offer is not 
consummated on or prior to 210 days after the Issue Date, or (iv) the Shelf 
Registration Statement is filed and declared effective within 210 days after 
the Issue Date but shall thereafter cease to be effective (at any time that 
the Company is obligated to maintain the effectiveness thereof) without being 
succeeded within 30 days by an additional Registration Statement filed and 
declared effective (each such event referred to in clauses (i) through (iv), 
a "Registration Default"), the Company shall pay liquidated damages to each 
Holder of 



                                                                              4

Transfer Restricted Securities, during the period of such Registration 
Default, in an amount equal to $0.192 per week per $1,000 principal amount of 
the Securities constituting Transfer Restricted Securities held by such 
Holder until the applicable Registration Statement is filed or declared 
effective, the Registered Exchange Offer is consummated or the Shelf 
Registration Statement again becomes effective, as the case may be.  All 
accrued liquidated damages shall be paid to Holders in the same manner as 
interest payments on the Securities on semi-annual payment dates which 
correspond to interest payment dates for the Securities.  Following the cure 
of all Registration Defaults, the accrual of liquidated damages will cease.  
The Trustee shall have no responsibility with respect to the determination of 
the amount of any such liquidated damages.  For purposes of the foregoing, 
"Transfer Restricted Securities" means (i) each Initial Security until the 
date on which such Initial Security has been exchanged for a freely 
transferable Exchange Security in the Registered Exchange Offer, (ii) each 
Initial Security or Private Exchange Security until the date on which such 
Initial Security or Private Exchange Security has been effectively registered 
under the Securities Act and disposed of in accordance with a Shelf 
Registration Statement or (iii) each Initial Security or Private Exchange 
Security until the date on which such Initial Security or Private Exchange 
Security is distributed to the public pursuant to Rule 144 under the 
Securities Act or is saleable pursuant to Rule 144(k) under the Securities 
Act.

2.   Method of Payment

          The Company will pay interest on the Securities (except defaulted 
interest) to the Persons who are registered Holders of Securities at the 
close of business on the February 1 or August 1 next preceding the interest 
payment date even if Securities are canceled after the record date and on or 
before the interest payment date.  Holders must surrender Securities to a 
Paying Agent to collect principal payments.  The Company will pay principal 
and interest in money of the United States of America that at the time of 
payment is legal tender for payment of public and private debts.  Payments in 
respect of the Securities represented by a Global Security (including 
principal, premium and interest) will be made by wire transfer of immediately 
available funds to the accounts specified by The Depository Trust Company.  
The Company, through the Paying Agent, will make all payments in respect of a 
certificated Security (including principal, premium and interest), by mailing 
a check to the registered address of each Holder thereof; provided, however, 
that payments on the Securities may also be made, in the case of a Holder of 
at least $1,000,000 aggregate principal amount of 



                                                                              5

Securities, by wire transfer to a U.S. dollar account maintained by the payee 
with a bank in the United States if such Holder elects payment by wire 
transfer by giving written notice to the Trustee or the Paying Agent to such 
effect designating such account no later than 30 days immediately preceding 
the relevant due date for payment (or such other date as the Trustee may 
accept in its discretion).

3.   Paying Agent and Registrar

          Initially, MARINE MIDLAND BANK, a New York banking corporation and 
trust company (the "Trustee"), will act as Paying Agent and Registrar.  The 
Company may appoint and change any Paying Agent, Registrar or co-registrar 
without notice.  The Company or any of its domestically incorporated 
Wholly-owned Subsidiaries may act as Paying Agent, Registrar or co-registrar.

4.   Indenture

          The Company issued the Securities under an Indenture dated as of 
February 12, 1998 (the "Indenture"), between the Company and the Trustee.  
The terms of the Securities include those stated in the Indenture and those 
made part of the Indenture by reference to the Trust Indenture Act of 1939 
(15 U.S.C. Sections  77aaa-77bbbb) as in effect on the date of the Indenture 
(the "TIA"). The Securities are subject to all such terms, and 
Securityholders are referred to the Indenture and the TIA for a statement of 
those terms.

          The Securities are senior subordinated unsecured obligations of the 
Company limited to $625,000,000 aggregate principal amount at any one time 
outstanding (subject to Section 2.07 of the Indenture).  This Security is one 
of the Initial Securities referred to in the Indenture issued in an aggregate 
principal amount of $625,000,000.  The Securities include the Initial 
Securities and any Exchange Securities and Private Exchange Securities issued 
in exchange for the Initial Securities pursuant to the Indenture.  The 
Initial Securities, the Private Exchange Securities and the Exchange 
Securities are treated as a single class of securities under the Indenture.  
The Indenture imposes certain limitations on the ability of the Company and 
its Restricted Subsidiaries to, among other things, make certain Investments 
and other Restricted Payments, pay dividends and other distributions, incur 
Indebtedness, enter into consensual restrictions upon the payment of certain 
dividends and distributions by such Restricted Subsidiaries, enter into or 
permit certain transactions with Affiliates, create or incur Liens and make 
asset sales.  The Indenture also imposes limitations on the 



                                                                              6

ability of the Company to consolidate or merge with or into any other Person 
or convey, transfer or lease all or substantially all of the property of the 
Company.

5.   Optional Redemption

          Except as set forth in the following paragraph, the Securities will 
not be redeemable at the option of the Company prior to February 15, 2003.  
The Securities will be redeemable at the option of the Company on or after 
such date, in whole or in part, upon not less than 30 nor more than 60 days 
prior notice, at the following redemption prices (expressed as percentages of 
principal amount), plus accrued and unpaid interest (if any) to the 
applicable redemption date (subject to the right of Holders of record on the 
relevant record date to receive interest due on the relevant interest payment 
date), if redeemed during the 12-month period commencing on February 15 of 
the years set forth below:



                                                               
                                                                    Redemption
Year                                                                   Prices  
- ----                                                                  -------
2003 ...........................................................     104.500%
2004 ...........................................................     103.000%
2005 ...........................................................     101.500%
2006 and thereafter ............................................     100.000%



          In addition, at any time and from time to time prior to February 
15, 2001, the Company may, at its option, redeem up to 35% of the original 
aggregate principal amount of Securities at a redemption price (expressed as 
a percentage of the principal amount) of 109%, plus accrued and unpaid 
interest thereon, if any, to the redemption date (subject to the right of 
Holders of record on the relevant record date to receive interest due on the 
relevant interest payment date), with the net cash proceeds of one or more 
Equity Offerings; provided that at least 65% of such original aggregate 
principal amount of Securities remains outstanding immediately after the 
occurrence of such redemption; and provided, further, that such redemption 
shall occur within 60 days of the date of the closing of any such Equity 
Offering.  Any such redemption shall be made upon not less than 30 nor more 
than 60 days notice mailed to each Holder of Securities being redeemed and 
otherwise in accordance with the procedures set forth in the Indenture.

6.   Sinking Fund

          The Securities are not subject to any sinking fund.





                                                                              7


7.   Notice of Redemption

          Notice of redemption will be mailed by first-class mail at least 30 
days but not more than 60 days before the redemption date to each Holder of 
Securities to be redeemed at his or her registered address.  Securities in 
denominations larger than $1,000 may be redeemed in part but only in whole 
multiples of $1,000.  If money sufficient to pay the redemption price of and 
accrued interest on all Securities (or portions thereof) to be redeemed on 
the redemption date is deposited with the Paying Agent on or before the 
redemption date and certain other conditions are satisfied, on and after such 
date interest ceases to accrue on such Securities (or such portions thereof) 
called for redemption.

8.   Repurchase of Securities at the Option of Holders upon Change of Control

          Upon a Change of Control, any Holder of Securities will have the 
right, subject to certain conditions specified in the Indenture, to cause the 
Company to repurchase all or any part of the Securities of such Holder at a 
purchase price equal to 101% of the principal amount of the Securities to be 
repurchased plus accrued and unpaid interest, if any, to the date of purchase 
(subject to the right of Holders of record on the relevant record date to 
receive interest due on the relevant interest payment date that is on or 
prior to the date of purchase) as provided in, and subject to the terms of, 
the Indenture.

9.   Subordination

          The Securities are subordinated to Senior Indebtedness, as defined 
in the Indenture.  To the extent provided in the Indenture, Senior 
Indebtedness must be paid before the Securities may be paid.  The Company 
agrees, and each Securityholder by accepting a Security agrees, to the 
subordination provisions contained in the Indenture and authorizes the 
Trustee to give it effect and appoints the Trustee as attorney-in-fact for 
such purpose.

10.  Denominations; Transfer; Exchange

          The Securities are in registered form without coupons in 
denominations of $1,000 and whole multiples of $1,000.  A Holder may transfer 
or exchange Securities in accordance with the Indenture.  Upon any transfer 
or exchange, the Registrar and the Trustee may require a Holder, among other 
things, to furnish appropriate endorsements or transfer 



                                                                              8

documents and to pay any taxes required by law or permitted by the Indenture. 
The Registrar need not register the transfer of or exchange any Securities 
selected for redemption (except, in the case of a Security to be redeemed in 
part, the portion of the Security not to be redeemed) or to transfer or 
exchange any Securities for a period of 15 days prior to a selection of 
Securities to be redeemed.

11.  Persons Deemed Owners

          The registered Holder of this Security may be treated as the owner 
of it for all purposes.

12.  Unclaimed Money

          If money for the payment of principal or interest remains unclaimed 
for two years, the Trustee or Paying Agent shall pay the money back to the 
Company at its written request unless an abandoned property law designates 
another Person.  After any such payment, Holders entitled to the money must 
look only to the Company and not to the Trustee for payment.

13.  Discharge and Defeasance

          Subject to certain conditions, the Company at any time may 
terminate some of or all its obligations under the Securities and the 
Indenture if the Company deposits with the Trustee money or U.S. Government 
Obligations for the payment of principal and interest on the Securities to 
redemption or maturity, as the case may be.

14.  Amendment, Waiver

          Subject to certain exceptions set forth in the Indenture, (i) the 
Indenture or the Securities may be amended or supplemented without prior 
notice to any Securityholder but with the written consent of the Holders of 
at least a majority in principal amount of the outstanding Securities and 
(ii) any default or compliance with any provision may be waived with the 
written consent of the Holders of at least a majority in principal amount of 
the outstanding Securities.  Subject to certain exceptions set forth in the 
Indenture, without the consent of any Holder of Securities, the Company and 
the Trustee may amend or supplement the Indenture or the Securities (i) to 
cure any ambiguity, defect or inconsistency; (ii) to comply with Article 5 of 
the Indenture; (iii) to provide for certificated or uncertificated Securities 
(provided that the uncertificated Securities are issued in registered form 
for purposes of Section 163(f) of the Code, or in a manner such that the 
uncertificated Securities are 



                                                                              9

described in Section 163(f)(2)(B) of the Code); (iv) to add Guarantees with 
respect to the Securities or to secure the Securities; (v) to add additional 
covenants for the benefit of the Holders or to surrender rights and powers 
conferred on the Company; (vi) to comply with the requirements of the SEC in 
connection with the qualification of the Indenture or the Trustee under the 
TIA; (vii) to make any change that does not adversely affect the rights of 
any Securityholder; (viii) to make any change in Article 10 of the Indenture 
that would limit or terminate the benefits available to any holder of Senior 
Indebtedness (or Representatives therefor) under Article 10 of the Indenture; 
or (ix) to provide for the issuance of the Exchange Securities or Private 
Exchange Securities.

15.  Defaults and Remedies

          If an Event of Default occurs and is continuing, the Trustee or the 
Holders of at least 25% in principal amount of the Securities then 
outstanding, subject to certain limitations, may declare all the Securities 
to be immediately due and payable.  Certain events of bankruptcy or 
insolvency are Events of Default and shall result in the Securities being 
immediately due and payable upon the occurrence of such Events of Default 
without any further act of the Trustee or any Holder.

          Holders of Securities may not enforce the Indenture or the 
Securities except as provided in the Indenture.  The Trustee may refuse to 
enforce the Indenture or the Securities unless it receives reasonable 
indemnity or security. Subject to certain limitations, Holders of a majority 
in principal amount of the Securities may direct the Trustee in its exercise 
of any trust or power under the Indenture.  The Holders of a majority in 
aggregate principal amount of the Securities, by written notice to the 
Trustee and the Company, may rescind any declaration of acceleration and its 
consequences if the rescission would not conflict with any judgment or 
decree, and if all existing Events of Default have been cured or waived 
except nonpayment of principal or interest that has become due solely because 
of the acceleration.

16.  Trustee Dealings with the Company

          Subject to certain limitations imposed by the TIA,  the Trustee 
under the Indenture, in its individual or any other capacity, may become the 
owner or pledgee of Securities and may otherwise deal with and collect 
obligations owed to it by the Company or its Affiliates and may otherwise 
deal with 



                                                                             10

the Company or its Affiliates with the same rights it would have if it were not
Trustee.

17.  No Personal Liability of Directors, Officers, Employees and Stockholders

          No director, officer, employee or stockholder of the Company shall 
have any liability for any obligations of the Company under the Securities or 
the Indenture or for any claim based on, in respect of, or by reason of such 
obligations or their creation.  Each Securityholder by accepting a Security 
waives and releases all such liability.  The waiver and release are part of 
the consideration for issuance of the Securities. 

18.  Authentication

          This Security shall not be valid until an authorized signatory of 
the Trustee (or an authenticating agent) manually signs the certificate of 
authentication on the other side of this Security.

19.  Abbreviations

          Customary abbreviations may be used in the name of a Securityholder 
or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by 
the entireties), JT TEN (=joint tenants with rights of survivorship and not 
as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to 
Minors Act).

20.  Governing Law

          THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE 
WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO 
APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION 
OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

21.  CUSIP Numbers

          Pursuant to a recommendation promulgated by the Committee on 
Uniform Security Identification Procedures, the Company has caused CUSIP 
numbers to be printed on the Securities and has directed the Trustee to use 
CUSIP numbers in notices of redemption as a convenience to Securityholders.  
No representation is made as to the accuracy of such numbers either as 
printed on the Securities or as contained in any notice of redemption and 
reliance may be placed only on the other identification numbers placed 
thereon.



                                                                             11


          The Company will furnish to any Holder of Securities upon written 
request and without charge to the Holder a copy of the Indenture which has in 
it the text of this Security.

              [FORM OF REVERSE SIDE OF EXCHANGE SECURITY]   

                9% Senior Subordinated Note due 2008


          Capitalized terms used but not defined herein shall have the meanings
given to such terms in the Indenture (as defined).

1.   Interest

          MAGELLAN HEALTH SERVICES, INC., a Delaware corporation (such
corporation, and its successors and assigns under the Indenture hereinafter
referred to, being herein called the "Company"), promises to pay interest on the
principal amount of this Security at the rate per annum shown above.  The
Company will pay interest semiannually on February 15 and August 15 of each
year, commencing on August 15, 1998.  Interest on the Securities will accrue
from the most recent date to which interest has been paid or, if no interest has
been paid, from February 12, 1998.  Interest will be computed on the basis of a
360-day year of twelve 30-day months.  The Company shall pay interest on overdue
principal at the rate borne by the Securities plus 1% per annum, and it shall
pay interest on overdue installments of interest at the same rate to the extent
lawful.

2.   Method of Payment

          The Company will pay interest on the Securities (except defaulted
interest) to the Persons who are registered Securityholders at the close of
business on the February 1 or August 1 next preceding the interest payment date
even if Securities are canceled after the record date and on or before the
interest payment date.  Holders must surrender Securities to a Paying Agent to
collect principal payments.  The Company will pay principal and interest in
money of the United States of America that at the time of payment is legal
tender for payment of public and private debts.  Payments in respect of the
Securities represented by a Global Security (including principal, premium and
interest) will be made by wire transfer of immediately available funds to the
accounts specified by The Depository Trust Company.  The Company, through the
Paying Agent, will make all payments in respect of a certificated Security
(including principal, premium and interest), by mailing a check to the
registered address of each Holder thereof; provided, however, that payments on
the Securities may also be made, in the case of a Holder of at least $1,000,000
aggregate principal amount of Securities, by wire transfer to a U.S. dollar
account maintained by the payee with 




                                                                              4

a bank in the United States if such Holder elects payment by wire transfer by
giving written notice to the Trustee or the Paying Agent to such effect
designating such account no later than 30 days immediately preceding the
relevant due date for payment (or such other date as the Trustee may accept in
its discretion).

3.   Paying Agent and Registrar

          Initially, MARINE MIDLAND BANK, a New York banking corporation and
trust company (the "Trustee"), will act as Paying Agent and Registrar.  The
Company may appoint and change any Paying Agent, Registrar or co-registrar
without notice.  The Company or any of its domestically incorporated
Wholly-owned Subsidiaries may act as Paying Agent, Registrar or co-registrar.

4.   Indenture

          The Company issued the Securities under an Indenture dated as of
February 12, 1998 (the "Indenture"), between the Company and the Trustee.  The
terms of the Securities include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
Sections  77aaa-77bbbb) as in effect on the date of the Indenture (the "TIA"). 
The Securities are subject to all such terms, and Securityholders are referred
to the Indenture and the TIA for a statement of those terms.

          The Securities are senior subordinated unsecured obligations of the
Company limited to $625,000,000 aggregate principal amount at any one time
outstanding (subject to Section 2.07 of the Indenture).  This Security is one of
the Securities referred to in the Indenture.  The Securities include the Initial
Securities and any Exchange Securities and Private Exchange Securities issued in
exchange for the Initial Securities pursuant to the Indenture.  The Initial
Securities, the Exchange Securities and the Private Exchange Securities are
treated as a single class of securities under the Indenture.  The Indenture
imposes certain limitations on the ability of the Company and its Restricted
Subsidiaries to, among other things, make certain Investments and other
Restricted Payments, pay dividends and other distributions, incur Indebtedness,
enter into consensual restrictions upon the payment of certain dividends and
distributions by such Restricted Subsidiaries, enter into or permit certain
transactions with Affiliates, create or incur Liens and make asset sales.  The
Indenture also imposes limitations on the ability of the Company to consolidate
or merge with or into 




                                                                              5

any other Person or convey, transfer or lease all or substantially all of the
property of the Company.


5.   Optional Redemption

          Except as set forth in the following paragraph, the Securities will
not be redeemable at the option of the Company prior to February 15, 2003.  The
Securities will be redeemable at the option of the Company on or after such
date, in whole or in part, upon not less than 30 nor more than 60 days prior
notice, at the following redemption prices (expressed as percentages of
principal amount), plus accrued and unpaid interest (if any) to the applicable
redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date), if
redeemed during the 12-month period commencing on February 15 of the years set
forth below:




                                                                  Redemption    
Year                                                                Prices    
- -----                                                             ----------
                                                              
2003      ..................................................       104.500%
2004      ..................................................       103.000%
2005      ..................................................       101.500%
2006 and thereafter.........................................       100.000%




          In addition, at any time and from time to time prior to February 15,
2001, the Company may, at its option, redeem up to 35% of the original aggregate
principal amount of Securities at a redemption price (expressed as a percentage
of the principal amount) of 109%, plus accrued and unpaid interest thereon, if
any, to the redemption date (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date), with the net cash proceeds of one or more Equity Offerings; provided that
at least 65% of such original aggregate principal amount of Securities remains
outstanding immediately after the occurrence of such redemption; and provided,
further, that such redemption shall occur within 60 days of the date of the
closing of any such Equity Offering.  Any such redemption shall be made upon not
less than 30 nor more than 60 days notice mailed to each Holder of Securities
being redeemed and otherwise in accordance with the procedures set forth in the
Indenture.

6.   Sinking Fund

          The Securities are not subject to any sinking fund.





                                                                              6

7.   Notice of Redemption

          Notice of redemption will be mailed by first-class mail at least
30 days but not more than 60 days before the redemption date to each Holder of
Securities to be redeemed at his or her registered address.  Securities in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000.  If money sufficient to pay the redemption price of and
accrued interest on all Securities (or portions thereof) to be redeemed on the
redemption date is deposited with the Paying Agent on or before the redemption
date and certain other conditions are satisfied, on and after such date interest
ceases to accrue on such Securities (or such portions thereof) called for
redemption.

8.   Repurchase of Securities at the Option of Holders upon Change of Control

          Upon a Change of Control, any Holder of Securities will have the
right, subject to certain conditions specified in the Indenture, to cause the
Company to repurchase all or any part of the Securities of such Holder at a
purchase price equal to 101% of the principal amount of the Securities to be
repurchased plus accrued and unpaid interest, if any, to the date of purchase
(subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date that is on or prior
to the date of purchase) as provided in, and subject to the terms of, the
Indenture.

9.   Subordination

          The Securities are subordinated to Senior Indebtedness, as defined in
the Indenture.  To the extent provided in the Indenture, Senior Indebtedness
must be paid before the Securities may be paid.  The Company agrees, and each
Securityholder by accepting a Security agrees, to the subordination provisions
contained in the Indenture and authorizes the Trustee to give it effect and
appoints the Trustee as attorney-in-fact for such purpose.


10.  Denominations; Transfer; Exchange

          The Securities are in registered form without coupons in denominations
of $1,000 and whole multiples of $1,000.  A Holder may transfer or exchange
Securities in accordance with the Indenture.  Upon any transfer or exchange, the
Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements or transfer 



                                                                              7

documents and to pay any taxes required by law or permitted by the Indenture. 
The Registrar need not register the transfer of or exchange any Securities
selected for redemption (except, in the case of a Security to be redeemed in
part, the portion of the Security not to be redeemed) or to transfer or exchange
any Securities for a period of 15 days prior to a selection of Securities to be
redeemed.

11.  Persons Deemed Owners

          The registered Holder of this Security may be treated as the owner of
it for all purposes.

12.  Unclaimed Money

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its written request unless an abandoned property law designates
another Person.  After any such payment, Holders entitled to the money must look
only to the Company and not to the Trustee for payment.

13.  Discharge and Defeasance

          Subject to certain conditions, the Company at any time may terminate
some of or all its obligations under the Securities and the Indenture if the
Company deposits with the Trustee money or U.S. Government Obligations for the
payment of principal and interest on the Securities to redemption or maturity,
as the case may be.

14.  Amendment, Waiver

          Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended or supplemented without prior notice
to any Securityholder but with the written consent of the Holders of at least a
majority in principal amount of the outstanding Securities and (ii) any default
or compliance with any provision may be waived with the written consent of the
Holders of at least a majority in principal amount of the outstanding
Securities.  Subject to certain exceptions set forth in the Indenture, without
the consent of any Holder of Securities, the Company and the Trustee may amend
or supplement the Indenture or the Securities (i) to cure any ambiguity, defect
or inconsistency; (ii) to comply with Article 5 of the Indenture; (iii) to
provide for certificated or uncertificated Securities (provided that the
uncertificated Securities are issued in registered form for purposes of Section
163(f) of the Code, or in a manner such that the uncertificated Securities are 



                                                                              8

described in Section 163(f)(2)(B) of the Code); (iv) to add Guarantees with
respect to the Securities or to secure the Securities; (v) to add additional
covenants for the benefit of the Holders or to surrender rights and powers
conferred on the Company; (vi) to comply with the requirements of the SEC in
connection with the qualification of the Indenture or the Trustee under the TIA;
(vii) to make any change that does not adversely affect the rights of any
Securityholder; (viii) to make any change in Article 10 of the Indenture that
would limit or terminate the benefits available to any holder of Senior
Indebtedness (or Representatives therefor) under Article 10 of the Indenture; or
(ix) to provide for the issuance of the Exchange Securities or Private Exchange
Securities.


15.  Defaults and Remedies

          If an Event of Default occurs and is continuing, the Trustee or the 
Holders of at least 25% in principal amount of the Securities then 
outstanding, subject to certain limitations, may declare all the Securities 
to be immediately due and payable.  Certain events of bankruptcy or 
insolvency are Events of Default and shall result in the Securities being 
immediately due and payable upon the occurrence of such Events of Default 
without any further act of the Trustee or any Holder.

          Holders of Securities may not enforce the Indenture or the Securities
except as provided in the Indenture.  The Trustee may refuse to enforce the
Indenture or the Securities unless it receives reasonable indemnity or security.
Subject to certain limitations, Holders of a majority in principal amount of the
Securities may direct the Trustee in its exercise of any trust or power under
the Indenture.  The Holders of a majority in aggregate principal amount of the
Securities, by written notice to the Trustee and the Company, may rescind any
declaration of acceleration and its consequences if the rescission would not
conflict with any judgment or decree, and if all existing Events of Default have
been cured or waived except nonpayment of principal or interest that has become
due solely because of the acceleration.

16.  Trustee Dealings with the Company

          Subject to certain limitations imposed by the TIA,  the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with 



                                                                              9

the Company or its Affiliates with the same rights it would have if it were not
Trustee.

17.  No Personal Liability of Directors, Officers, Employees and Stockholders

          No director, officer, employee or stockholder of the Company shall
have any liability for any obligations of the Company under the Securities or
the Indenture or for any claim based on, in respect of, or by reason of such
obligations or their creation.  Each Securityholder by accepting a Security
waives and releases all such liability.  The waiver and release are part of the
consideration for issuance of the Securities. 

18.  Authentication

          This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

19.  Abbreviations

          Customary abbreviations may be used in the name of a Securityholder or
an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).

20.  Governing Law

          THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE
PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF
ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

21.  CUSIP Numbers

          Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be
printed on the Securities and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders.  No representation is
made as to the accuracy of such numbers either as printed on the Securities or
as contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.




                                                                             10

          The Company will furnish to any Holder of Securities upon written
request and without charge to the Holder a copy of the Indenture which has in it
the text of this Security.  





                                                                     11

                        Transferee Letter of Representation]


Ladies and Gentlemen:

          This certificate is delivered to request a transfer of
$__________ principal amount of the 9% Senior Subordinated Notes due 2008 (the
"Securities") of Magellan Health Services, Inc. (the "Company").

          Upon transfer, the Securities would be registered in the name of the
new beneficial owner as follows:

          Name:______________________

          Address:___________________

          Taxpayer ID Number:________

          The undersigned represents and warrants to you that:

          1.  We are an institutional "accredited investor" (as defined in 
rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended 
(the "Securities Act")), purchasing for our own account or for the account of 
such an institutional "accredited investor" at least $250,000 principal 
amount of the Securities, and we are acquiring the Securities not with a view 
to, or for offer or sale in connection with, any distribution in violation of 
the Securities Act. We have such knowledge and experience in financial and 
business matters as to be capable of evaluating the merits and risks of our 
investment in the Securities, and we invest in or purchase securities similar 
to the Securities in the normal course of our business.  We, and any accounts 
for which we are acting, are each able to bear the economic risk of our or 
its investment.

          2.  We understand that the Securities have not been registered 
under the Securities Act and, unless so registered, may not be sold except as 
permitted in the following sentence.  We agree on our own behalf and on 
behalf of any investor account for which we are purchasing Securities to 
offer, sell or otherwise transfer such Securities prior to the date that is 
two years after the later of the date of original issue and the last date on 
which the Company or any affiliate of the Company was the owner of such 
Securities (or any predecessor thereto) (the "Resale Restriction Termination 
Date") only (a) to the Company, (b) pursuant to a registration statement that 
has been declared effective under the Securities Act, (c) in a 



                                                                               2

transaction complying with the requirements of Rule 144A under the Securities
Act ("Rule 144A"), to a person we reasonably believe is a qualified
institutional buyer under Rule 144A (a "QIB") that is purchasing for its own
account or for the account of a QIB and to whom notice is given that the
transfer is being made in reliance on Rule 144A, (d) in an offshore transaction
within the meaning of, and in compliance with, Regulation S under the Securities
Act, (e) to an institutional "accredited investor" within the meaning of
Rule 501(a)(1), (2), (3) or (7) under the Securities Act that is purchasing for
its own account or for the account of such an institutional "accredited
investor," in each case in a minimum principal amount of Securities of $250,000,
or (f) pursuant to any other available exemption from the registration
requirements of the Securities Act, subject in each of the foregoing cases to
any requirement of law that the disposition of our property or the property of
such investor account or accounts be at all times within our or their control
and in compliance with any applicable state securities laws.  The foregoing
restrictions on resale will not apply subsequent to the Resale Restriction
Termination Date.  If any resale or other transfer of the Securities is proposed
