Security or Securities or in the form of Definitive Securities or both. A Global
Security  shall  represent  such  of the  outstanding  Securities  as  shall  be
specified therein and shall provide that it shall represent the aggregate amount
of  outstanding  Securities  from  time to time  endorsed  thereon  and that the
aggregate amount of outstanding  Securities represented thereby may from time to

of the Trustee. The signature shall be conclusive evidence that the Security has
been authenticated under this Indenture.

paying  agent.  The Company  may change any Paying  Agent or  Registrar  without
notice to any  Holder.  The Company  shall  notify the Trustee in writing of the
name and address of any Agent not a party to this Indenture,  such  notification
to be delivered,  together  with a  certificate  of such Agent that it agrees to
perform its duties in accordance with the procedures  established by the Trustee
and with the  terms of this  Indenture,  to the  Trustee  prior to the date such
Agent assumes its duties hereunder.  If the Company fails to appoint or maintain

Company or any of its Subsidiaries may act as Paying Agent or Registrar.

Section 2.4 Paying Agent to Hold Money in Trust

     The Company shall require each Paying Agent other than the Trustee to agree
in  writing  that the  Paying  Agent  will hold in trust for the  benefit of the
Holders or the  Trustee  all money held by the Paying  Agent for the  payment of

the Trustee of any default by the Company in making any such payment.  While any
such default continues,  the Trustee may require a Paying Agent to pay all money
held by it to the Trustee. The Company at any time may require a Paying Agent to
pay all money held by it to the Trustee.  Upon payment over to the Trustee,  the
Paying Agent (if other than the Company or a  Subsidiary)  shall have no further

shall segregate and hold in a separate trust fund for the benefit of the Holders
all money held by it as Paying Agent.

authentication order in the form of an Officers' Certificate,  the Trustee shall
authenticate a new Global Security in the appropriate principal amount.

     (c) The transfer and exchange of Global Securities or beneficial  interests
therein  shall be  effected  through the  Depositary,  in  accordance  with this
Indenture  (including  the  restrictions  on transfer set forth  herein) and the
procedures of the Depositary therefor.

     (d) With  respect to the  transfer  of a  beneficial  interest  in a Global
Security for a Definitive Security:

          (i) Any person having a beneficial  interest in a Global  Security may
     upon request exchange such beneficial  interest for a Definitive  Security.
     Upon receipt by the Trustee of written  instructions  or such other form of
     instructions as is customary for the Depositary or its nominee on behalf of
     any person having a beneficial interest in a Global Security constituting a
     Transfer


                                      -14-


     Restricted  Security only,  except if exchanged for an Exchange Note in the
     Exchange Offer, the following additional  information and documents (all of
     which may be submitted by facsimile):

               (A) if such  beneficial  interest  is  being  transferred  to the
          person  designated by the Depositary as being the beneficial  owner, a
          certification  from such person to that effect (in  substantially  the
          form of Exhibit C hereto); or ---------

               (B)  if  such  beneficial  interest  is  being  transferred  to a
          "qualified  institutional  buyer"  (as  defined in Rule 144A under the
          Securities  Act) in accordance with Rule 144A under the Securities Act
          or pursuant to an exemption from  registration in accordance with Rule
          144 under the Securities Act or pursuant to an effective  registration
          statement  under the Securities  Act, a  certification  to that effect
          from the transferor (in  substantially  the form of Exhibit C hereto);
          or

               (C) if such beneficial  interest is being transferred in reliance
          on  another  exemption  from  the  registration  requirements  of  the
          Securities Act, a certification  to that effect from the transferee or
          transferor  (in  substantially  the form of  Exhibit C hereto)  and an
          opinion  of  counsel  from the  transferee  or  transferor  reasonably
          acceptable to the Company and to the Registrar to the effect that such
          transfer is in compliance with the Securities Act,

then the Trustee will cause,  in accordance with the standing  instructions  and
procedures  existing  between it and the  Depositary,  the  aggregate  principal
amount of the Global Security to be reduced and,  following such reduction,  the
Company will execute and, upon receipt of a written  authentication order in the
form of an Officers'  Certificate,  the Trustee will authenticate and deliver to
the transferee a Definitive Security.

          (ii)  Definitive  Securities  issued  in  exchange  for  a  beneficial
     interest  in a  Global  Security  pursuant  to this  Section  2.5  shall be
     registered  in such  names  and in  such  authorized  denominations  as the
     Depositary,   pursuant  to   instructions   from  its  direct  or  indirect
     participants  or  otherwise,  shall in writing  instruct the  Trustee.  The
     Trustee  shall deliver such  Definitive  Securities to the persons in whose
     name such Securities are so registered.

     (e)  Notwithstanding any other provisions of this Indenture (other than the
provisions set forth in subsection  (f) of this Section 2.5), 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.

     (f) The following relates to the authentication of Definitive Securities in
the  absence  of the  Depositary.  If at any time:  (i) the  Depositary  for the
Securities  notifies the Company that the  Depositary  is unwilling or unable to
continue as Depositary for the Global Securities and a successor  Depositary for
the Global  Securities  is not  appointed  by the  Company  within 90 days after
delivery of such notice; or (ii) the Company,  at its sole discretion,  notifies
the  Trustee  in  writing  that it elects to cause the  issuance  of  Definitive
Securities under this Indenture, then the Company will execute, and the Trustee,
upon  receipt  of a  written  order  in the  form  of an  Officers'  Certificate
requesting  the  authentication  and  delivery of  Definitive  Securities,  will
authenticate and deliver Definitive Securities, in an aggregate principal amount
equal to the  principal  amount of the Global  Securities,  in exchange for such
Global Securities.

     (g) (i) Except as otherwise  agreed to by the Company,  the Trustee and the
Holder thereof or as permitted by the following  paragraph  (ii), each Rule 144A
Note certificate  evidencing the Global Securities and the Definitive Securities
(and all  Securities  other than Exchange  Notes issued in exchange  therefor or
substitution thereof) shall bear a legend in substantially the following form:

     ABSENCE OF SUCH  REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR
     NOT SUBJECT TO, REGISTRATION UNDER SUCH LAWS.


                                      -15-



     THE HOLDER OF THIS SECURITY BY ITS  ACCEPTANCE  HERETO AGREES NOT TO OFFER,

     SECURITIES  ACT THAT  PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A

     CONTAINED IN THE INDENTURE IS COMPLETED AND DELIVERED BY THE  TRANSFEROR TO
     THE  TRUSTEE.  THIS  LEGEND  WILL BE REMOVED  UPON THE  REQUEST OF THE THEN
     HOLDER OF THIS SECURITY AFTER THE RESALE RESTRICTION  TERMINATION DATE. ANY
     TRANSFEREE OF THIS SECURITY SHALL BE DEEMED TO HAVE REPRESENTED  EITHER (A)
     THAT IT IS NOT USING THE ASSETS OF AN EMPLOYEE  BENEFIT PLAN SUBJECT TO THE
     EMPLOYEE  RETIREMENT  INCOME SECURITY ACT ("ERISA") OR THE INTERNAL REVENUE
     CODE (THE  "CODE") TO PURCHASE  THIS  SECURITY OR (B) THAT ITS PURCHASE AND
     CONTINUED  HOLDING OF THE SECURITY WILL BE COVERED BY A U.S.  DEPARTMENT OF
     LABOR  CLASS  EXEMPTION  (WITH  RESPECT TO  PROHIBITED  TRANSACTIONS  UNDER
     SECTION 406(a) OF ERISA).

               (ii) Upon any sale or transfer of a Transfer  Restricted Security
          (including any Transfer  Restricted  Security  represented by a Global
          Security)  pursuant  to  Rule  144  under  the  Securities  Act  or an
          effective  registration  statement under the Securities Act (including
          the Shelf Registration Statement):

                    (A) in the case of any 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 legend set forth above
               and  rescind any  restriction  on the  transfer of such  Transfer
               Restricted Security; and

                    (B) any such Transfer Restricted  Security  represented by a
               Global  Security shall not be subject to the provisions set forth
               in (i) above (such sales or transfers  being  subject only to the
               provisions of Section 2.5(c)  hereof);  provided,  however,  that
               with  respect  to any  request  for  an  exchange  of a  Transfer
               Restricted  Security that is represented by a Global Security for
               a Definitive Security that does not bear a legend,  which request
               is made in reliance  upon Rule 144 or an  effective  registration
               statement,  the Holder  thereof  shall  certify in writing to the
               Registrar that such request is being made pursuant to Rule 144 or
               an effective  registration  statement (such  certification  to be
               substantially in the form of Exhibit C hereto.)


                                      -16-



     (h) At such time as all  beneficial  interests  in a Global  Security  have
either been  exchanged  for  Definitive  Securities,  redeemed,  repurchased  or
cancelled,  such Global  Security shall be returned to or retained and cancelled
by the  Trustee.  At any time  prior  to such  cancellation,  if any  beneficial
interest in a Global Security is exchanged for Definitive Securities,  redeemed,
repurchased or cancelled, the principal amount of Securities represented by such
Global Security shall be reduced and an endorsement shall be made on such Global
Security,  by the Trustee or the Securities  Custodian,  at the direction of the
Trustee, to reflect such reduction.

     (i) All  Definitive  Securities  and  Global  Securities  issued  upon  any
registration  of  transfer  or  exchange  of  Definitive  Securities  or  Global
Securities  shall be the valid  obligations of the Company,  evidencing the same
debt, and entitled to the same benefits under this Indenture,  as the Definitive
Securities or Global  Securities  surrendered upon such registration of transfer
or exchange.

     No  service  charge  shall  be made to a  Holder  for any  registration  of
transfer or exchange (except as otherwise expressly  permitted herein),  but the
Company may require  payment of a sum  sufficient  to cover any  transfer tax or
similar  governmental  charge payable and any other expenses (including the fees
and expenses of the Trustee) in connection  therewith  (other than such transfer
tax or similar  governmental  charge payable upon exchanges  pursuant to Section
2.6 or 9.5).

Section 2.6 Replacement Securities

     If any mutilated Security is surrendered to the Trustee, or the Company and
the Trustee receive evidence to their  satisfaction of the destruction,  loss or
theft of any Security, the Company shall issue and the Trustee, upon the written
order of the Company  signed by two Officers,  shall  authenticate a replacement
Security if the  Trustee's  requirements  are met. If required by the Trustee or
the Company, an indemnity bond must be supplied by the Holder that is sufficient
in the  judgment of the Trustee  and the  Company to protect  the  Company,  the
Trustee,  the Agent or any authenticating  agent from any loss which any of them
may suffer if a Security is replaced. The Company and the Trustee may charge for
their expenses in replacing a Security.

     Every replacement Security is an additional obligation of the Company.

Section 2.7 Outstanding Securities

     The Securities outstanding at any time are all the Securities authenticated
by the  Trustee  except for those  canceled  by it,  those  delivered  to it for
cancellation and those described in this Section 2.7 as not outstanding.

     If a  Security  is  replaced  pursuant  to  Section  2.6,  it  ceases to be
outstanding  unless  the  Trustee  receives  proof  satisfactory  to it that the
replaced Security is held by a bona fide purchaser.

     If the principal  amount of any Security is  considered  paid under Section
4.1, it ceases to be  outstanding  and interest on it ceases to accrue as of the
date it is deemed paid. Upon a "legal defeasance"  pursuant to Section 8.1(b) or
a "covenant  defeasance"  pursuant to Section  8.1(c),  the Securities  shall be
deemed to be  outstanding  or not  outstanding  as  provided  in the  applicable
Section 8.1(b) or 8.1(c).

     Except  as set  forth in  Section  2.8,  a  Security  does not  cease to be
outstanding because the Company or an Affiliate holds the Security.

Section 2.8 Treasury Securities

     In  determining  whether the Holders of the  required  principal  amount of
Securities have concurred in any direction,  waiver or consent, Securities owned
by the Company or by any Person directly or indirectly controlling or controlled
by or  under  direct  or  indirect  common  control  with the  Company  shall be
considered  as  though  not  outstanding,   except  that  for  the  purposes  of
determining  whether  the  Trustee  shall be  protected  in  relying on any such
direction,  waiver or consent,  only Securities which the Trustee actually knows
are so owned shall be so disregarded.


                                      -17-



Section 2.9 Temporary Securities

     Until 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 in exchange for temporary Securities.

Section 2.10 Cancellation

     The  Company  at  any  time  may  deliver  Securities  to the  Trustee  for
cancellation.  The  Registrar  and Paying Agent shall forward to the Trustee any
Securities  surrendered  to them  for  registration  of  transfer,  exchange  or
payment. The Trustee shall cancel all Securities surrendered for registration of
transfer, exchange, payment,  replacement or cancellation,  and, upon request of
the  Company,  certification  of their  destruction  shall be  delivered  to the
Company  unless,  by a written order signed by two  Officers,  the Company shall
direct that canceled Securities be returned to it. The Company may not issue new
Securities to replace Securities that it has paid or that have been delivered to
the Trustee for cancellation.

Section 2.11 Defaulted Interest

     If the Company  defaults in a payment of  interest  on the  Securities,  it
shall pay the  defaulted  interest  in any  lawful  manner  plus,  to the extent
lawful,  interest  payable on the  defaulted  interest,  to the  Persons who are
Holders on a subsequent  special  record date, in each case at the rate provided
in the Securities.  The Company, with the consent of the Trustee, shall fix each
such special  record date and payment  date. At least 15 days before the special
record date, the Company (or, upon written request of the Company,  the Trustee,
in the name of and at the expense of the Company) shall mail to Holders a notice
that states the special record date, the related  payment date and the amount of
such interest to be paid.

Section 2.12 Securities Issuable in the Form of a Global Security

     (a) If the Company shall  establish that the Securities are to be issued in
whole or in part in the form of one or more Global Securities,  then the Company
shall execute and the Trustee or an agent  thereof  shall,  in  accordance  with
Section 2.2 and the written order of the Company delivered to the Trustee or its
agent  thereunder,  authenticate and deliver such Global Security or Securities,
which (i) shall  represent,  and shall be  denominated in an amount equal to the
aggregate  principal  amount of the outstanding  Securities to be represented by
such Global Security or Securities, or such portion thereof as the Company shall
specify in a written order of the Company signed by two Officers,  (ii) shall be
registered in the name of the Depositary for such Global  Security or Securities
or its  nominee,  (iii)  shall be  delivered  by the Trustee or its agent to the
Depositary  or pursuant to the  Depositary's  instruction  and (iv) shall bear a
legend substantially to the following effect:  "Unless and until it is exchanged
in whole or in part for securities in definitive  form, this security may not be
transferred  except as a whole 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.  Unless this certificate is presented by
an authorized  representative  of the Depositary to the Company or its agent for
registration of transfer,  exchange,  or payment,  and any certificate issued is
registered in the name of the nominee of the Depositary or in such other name as
is requested by an authorized  representative of the Depositary (and any payment
is made to the nominee of the Depositary or to such other entity as is requested
by an authorized  representative  of the Depositary),  ANY TRANSFER,  PLEDGE, OR
OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch
as the registered owner hereof,  the nominee of the Depositary,  has an interest
herein."

     (b)  Notwithstanding any other provision of this Section 2.12 or of Section
2.5, and subject to the provisions of paragraph (c) below, a Global Security may
be  transferred,  in whole but not in part and in the manner provided in Section
2.5, only to a nominee of the  Depositary  for such Global  Security,  or to the
Depositary,  or a  successor  Depositary  for such Global  Security  selected or
approved by the Company, or to a nominee of such successor Depositary.

     (c) (i) If at any time the  Depositary for a Global  Security  notifies the
Company that it is


                                      -18-



unwilling or unable to continue as Depositary for such Global  Security or if at
any time the  Depositary  for the  Securities  shall no longer be eligible or in
good  standing  under  the  Exchange  Act or any  other  applicable  statute  or
regulation,  the Company  shall appoint a successor  Depositary  with respect to
such Global Security.  If a successor Depositary for such Global Security is not
appointed by the Company  within 90 days after the Company  receives such notice
or becomes  aware of such  ineligibility,  the  Company  will  execute,  and the
Trustee or an agent  thereof,  upon  receipt of a written  order of the  Company
signed  by two  Officers  for the  authentication  and  delivery  of  individual
Definitive  Securities in exchange for such Global Security,  will  authenticate
and  deliver,  individual  Definitive  Securities  of like tenor and terms in an
aggregate  principal amount equal to the principal amount of the Global Security
in exchange for such Global Security.

          (ii) The Company may at any time and in its sole discretion  determine
     that the  Securities  issued in the form of one or more  Global  Securities
     shall no longer be  represented by such Global  Security or Securities.  In
     such event the Company will  execute,  and the  Trustee,  upon receipt of a
     written order of the Company signed by two Officers for the  authentication
     and delivery of individual Definitive Securities in exchange in whole or in
     part for such Global Security,  will  authenticate  and deliver  individual
     Definitive  Securities  of like tenor and terms in an  aggregate  principal
     amount equal to the principal  amount of such Global Security or Securities
     in exchange for such Global Security or Securities.

          (iii) If specified by the Company  pursuant to a written  order of the
     Company signed by two Officers,  the  Depositary for a Global  Security may
     surrender  such  Global  Security  in  exchange  in  whole  or in part  for
     individual  Definitive  Securities of like tenor and terms on such terms as
     are  acceptable to the Company and such  Depositary.  Thereupon the Company
     shall execute, and the Trustee or an agent thereof, upon a written order of
     the Company signed by two Officers, shall authenticate and deliver, without
     service  charge,  (1) to each Person  specified  by such  Depositary  a new
     Definitive  Security  or  Securities  of like  tenor  and  terms and of any
     authorized  denomination  as  requested  by  such  Person  in an  aggregate
     principal  amount  equal to and in exchange  for such  Person's  beneficial
     interest as specified by such Depositary in the Global Security; and (2) to
     such  Depositary  a new Global  Security  of like tenor and terms and in an
     authorized  denomination  equal  to the  difference,  if any,  between  the
     principal  amount of the  surrendered  Global  Security  and the  aggregate
     principal amount of Definitive Securities delivered to Holders thereof.

          (iv) In any  exchange  provided  for in (i),  (ii)  or  (iii)  of this
     paragraph (c), the Company will execute and the Trustee or an agent thereof
     will  authenticate  and  deliver   individual   Definitive   Securities  in
     registered  form in  authorized  denominations.  Upon the  exchange  of the
     entire  principal  amount of a Global  Security for  individual  Definitive
     Securities,  such Global Securities shall be cancelled by the Trustee or an
     agent  thereof.  Except as provided in (iii) above,  Definitive  Securities
     issued in exchange for a Global Security  pursuant to this Section shall be
     registered  in such  names  and in  such  authorized  denominations  as the
     Depositary  for such Global  Security,  pursuant to  instructions  from its
     direct or indirect  participants  or otherwise,  shall instruct  either the
     Trustee or the Registrar.  Such Trustee or the Registrar shall deliver such
     Definitive  Securities to the Persons in whose names such Securities are so
     registered.


                                   ARTICLE 3.

                                  -19-


Section 3.2 Selection of Securities to Be Redeemed or Purchased

     (a) If less  than all of the  Securities  are to be  redeemed  pursuant  to
Section 3.7, the Trustee  shall  select the  Securities  to be redeemed on a pro
rata basis,  by lot or in such other  manner as the Trustee  shall deem fair and
equitable;  provided,  however,  that in the  case of a  partial  redemption  of
Securities made with the proceeds of a Public Equity Offering,  selection of the
Securities for redemption shall be made on a pro rata basis,  unless such method
is otherwise  prohibited (in which case the Securities to be purchased  shall be
selected  by lot or in such  other  manner as the  Trustee  shall  deem fair and
equitable).  The particular Securities to be redeemed shall be selected,  unless
otherwise provided herein, prior to the date notice of redemption is required to
be sent by the Trustee,  from the outstanding  Securities not previously  called
for redemption.

     The Trustee  promptly shall notify the Company in writing of the Securities
selected for  redemption  and, in the case of any Security  selected for partial
redemption, the principal amount thereof to be redeemed. Securities and portions
of them selected shall be in amounts of $1,000 or integral  multiples of $1,000.
Provisions of this Indenture that apply to Securities called for redemption also
apply to portions of Securities called for redemption.

     (b) If less than all of the  Securities  are to be  purchased  pursuant  to
Section 3.8, the Trustee  shall select the  Securities  to be purchased on a pro
rata  basis,  unless  such  method is  otherwise  prohibited  (in which case the
Securities  to be purchased  shall be selected by lot or in such other manner as
the Trustee  shall deem fair and  equitable).  The  particular  Securities to be
purchased shall be selected, unless otherwise provided herein, prior to the date
notice of purchase is required to be sent by the Trustee,  from the  outstanding
Securities tendered pursuant to the Asset Sale Offer.

     The Trustee  promptly shall notify the Company in writing of the Securities
selected  for  purchase  and, in the case of any  Security  selected for partial
purchase, the principal amount thereof to be purchased.  Securities and portions
of them selected shall be in amounts of $1,000 or integral  multiples of $1,000.
Provisions of this Indenture  that apply to Securities  called for purchase also
apply to portions of Securities called for purchase.


Section 3.3 Notices to Holders

     (a) At least 30 days but not more than 60 days  before a  redemption  date,
the  Company  shall  mail a notice to each  Holder  whose  Securities  are to be
redeemed.

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

          (1) the redemption date;

          (2) the redemption price;

          (3) if any  Security  is being  redeemed  in part,  the portion of the
     principal  amount of such  Security  to be  redeemed  and  that,  after the
     redemption  date,  upon  surrender  of such  Security,  a new  Security  or
     Securities  in  principal  amount equal to the  unredeemed  portion will be
     issued;

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

          (5) that  Securities  called for redemption must be surrendered to the
     Paying  Agent at the  address  specified  in such  notice  to  collect  the

          (6) that interest on Securities called for redemption ceases to accrue
     on and after the  redemption  date  (unless  the  Company  defaults  on its
     obligation to repurchase Securities);

          (7) the paragraph of the  Securities  pursuant to which the Securities
     are being redeemed; and

          (8) the  aggregate  principal  amount  of  Securities  that are  being
     redeemed.


    
                                  -20-



     (b) If the  Company  determines  to make an Asset Sale Offer as provided in
Section 3.8, the Company shall promptly mail a notice to each Holder.

     The Notice shall state:

          (1) that an Asset Sale Offer is being made pursuant to Section 3.8 and
     the length of time the Asset Sale Offer will remain open;

          (2) the purchase price and the Asset Sale Payment Date;

          (3) the  aggregate  principal  amount of  Securities  the  Company  is
     offering to purchase;

          (4) that any  Security  not  tendered  or accepted  for  payment  will

          (5) that any Security  accepted for payment pursuant to the Asset Sale

          (6) that Holders electing to have a Security purchased pursuant to any
     Asset Sale Offer will be required to surrender the Security,  with the form
     entitled  "Option of Holder to Elect  Purchase"  on the reverse side of the
     Security  completed,  to the  Company,  a  depositary,  if appointed by the
     Company,  or a Paying Agent at the address specified in the notice prior to
     expiration of the Asset Sale Offer Period;

          (7) that  Holders will be entitled to withdraw  their  election if the
     Company,  depositary or Paying  Agent,  as the case may be,  receives,  not
     later than the  expiration of the Asset Sale Offer  Period,  or such longer
     period as may be required by law, a telegram, telex, facsimile transmission
     or letter setting forth the name of the Holder, the principal amount of the
     Security the Holder delivered for purchase and a statement that such Holder
     is withdrawing his election to have the Security purchased;

          (8) that, if the aggregate principal amount of Securities  surrendered
     by Holders exceeds the aggregate  principal amount of Securities offered to
     be purchased,  the Trustee shall select the Securities to be purchased on a
     pro rata basis,  unless such method is otherwise  prohibited (in which case
     the  Securities  to be purchased  shall be selected by lot or in such other
     manner as the Trustee shall deem fair and equitable); and

          (9) that Holders whose  Securities  are purchased only in part will be
     issued new Securities equal in principal amount to the unpurchased  portion
     of the Securities surrendered.


     (c) At the Company's request, the Trustee shall give the notice required in
Section  3.3(a) or 3.3(b) in the  Company's  name and at its expense;  provided,
however,  that the Company shall deliver to the Trustee,  at least 45 days prior
to  the  redemption  date  or  not  later  than  the  fifth  day  preceding  the
commencement  of an Asset Sale Offer  Period,  as the case may be, an  Officers'
Certificate  requesting  that the Trustee give such notice and setting forth the
information to be stated in such notice as provided in Section 3.3(a) or 3.3(b).

Section 3.4 Effect of Notice of Redemption

     Once notice of redemption  under Section 3.7 is mailed,  Securities  called
for redemption  become due and payable on the redemption  date at the redemption
price.  However,  if a redemption date is on or before an Interest  Payment Date
and on or after the related record date, any interest  accrued and unpaid to the
redemption  date shall be paid on such  Interest  Payment  Date to the person in
whose name the  Security is  registered  at the close of business on


    
                                  -21-


such  record  date and the only  remaining  right of the  Holders of  Securities
called for redemption  shall be to receive the redemption  price (excluding such
interest) upon surrender of such Securities to the Paying Agent.

Section 3.5 Deposit of Redemption Price or Purchase Price

     One  Business  Day prior to the  redemption  date or the Asset Sale Payment
Date, as the case may be, the Company shall deposit with the Trustee or with the
Paying Agent money  sufficient to pay the redemption price or the purchase price
of, and accrued  interest on, all Securities to be redeemed or purchased on that
date.  The Trustee or the Paying Agent shall return to the Company any money not
required for that purpose.

     If the  Company  complies  with the  preceding  paragraph,  interest on the
Securities  or portions  thereof to be redeemed or  purchased  (in the case of a
redemption, whether or not such Securities are presented for payment) will cease
to accrue on the applicable  redemption  date or Asset Sale Payment Date, as the
case may be. If any  Security  called for  redemption  shall not be so paid upon
surrender,  or if any Security to be purchased shall not be so paid on the Asset
Sale  Payment  Date,  because of the  failure of the  Company to comply with the
preceding paragraph, then interest will be paid on the unpaid principal from the
redemption  date or the Asset Sale Payment  Date, as the case may be, until such
principal is paid and on any interest not paid on such unpaid principal, in each
case, at the rate provided in the Securities and in Section 4.1.

Section 3.6 Securities Redeemed or Purchased in Part

     Upon  surrender of a Security  that is redeemed or  purchased in part,  the
Company shall issue,  and the Trustee shall  authenticate  for the Holder at the
expense  of the  Company,  a new  Security  equal  in  principal  amount  to the
unredeemed portion or the portion not purchased of the Security surrendered.

Section 3.7 Optional Redemption

     The Company may redeem all or any of the Securities at any time on or after
September 15, 2002, at the following redemption prices (expressed as percentages
of principal amount), plus accrued and unpaid interest to the redemption date:










                                      -22-



      If Redeemed During                   
the 12-month Period Commencing                   Redemption Price
- -------------------------------                  ----------------

 September 15, 2002                                  104.750%
 September 15, 2003                                  103.167%
 September 15, 2004                                  101.583%
 September 15, 2005 and thereafter                     100%


     Notwithstanding  the foregoing,  the Company may redeem in the aggregate up
to $150,000,000 principal amount of Securities at any time and from time to time
prior to  September  15,  2000 at a  redemption  price  equal to 108.500% of the
aggregate principal amount so redeemed,  plus accrued interest to the redemption
date,  out of the net cash  proceeds  of one or more  Public  Equity  Offerings;
provided that at least  $300,000,000  aggregate  principal  amount of Securities
originally  issued  remains   outstanding  after  the  occurrence  of  any  such
redemption  and that any such  redemption  occurs  within 60 days  following the
closing of any such Public Equity Offering.

     Any  redemption  pursuant to this Section 3.7 shall be made,  to the extent
applicable, in accordance with the provisions of Sections 3.1 through 3.6.

Section 3.8 Asset Sale Offer

     If the Company  determines  to make an Asset Sale Offer,  the Company shall
promptly  mail  (with  notice to the  Trustee)  or shall  cause the  Trustee  to
promptly mail (in the Company's name and at its expense) notice of an Asset Sale
Offer to each Holder of  Securities  as set forth in Section  3.3(b).  The Asset
Sale Offer  shall be deemed to have  commenced  on the date of such  mailing and
shall terminate 30 days after its  commencement  unless a longer offering period
is required by law (the  "Asset  Sale Offer  Period").  On or prior to the fifth
Business  Day  following  the  termination  of the Asset Sale Offer  Period (the
"Asset Sale Payment Date"), the Company shall purchase,  or cause the Trustee to
purchase,  and mail or deliver  payment  for,  as  selected  on a pro rata basis
(unless such method is otherwise prohibited,  in which case the Securities to be
purchased  shall be  selected  by lot,  with such  adjustments  as may be deemed
appropriate by the Company so that only Securities in denominations of $1,000 or
integral  multiples  thereof shall be purchased,  or in such other manner as the
Trustee shall deem fair and equitable) from Holders  tendering their  Securities
pursuant  to the Asset Sale  Offer,  the  amount of  Securities  required  to be
purchased  pursuant to Section  4.11.  If the Asset Sale  Payment  Date is on or
after an interest  payment  record  date and on or before the  related  interest
payment  date,  any accrued  interest will be paid to the person in whose name a
Security is  registered  at the close of business  on such record  date,  and no
additional interest will be payable to Holders who tender Securities pursuant to
the Asset Sale Offer. Any Asset Sale Offer shall be conducted in compliance with
applicable  tender offer rules,  including Section 14(e) of the Exchange Act and
Rule 14e-1 thereunder.

     On or before  any Asset  Sale  Payment  Date,  the  Company,  to the extent
lawful,  shall (i) accept for payment,  as selected on a pro rata basis  (unless
such  method  is  otherwise  prohibited,  in  which  case the  Securities  to be
purchased  shall be  selected  by lot,  with  such  adjustment  as may be deemed
appropriate by the Company so that only Securities in denominations of $1,000 or
integral  multiples  thereof shall be purchased,  or in such other manner as the
Trustee shall deem fair and equitable),  Securities or portions thereof tendered
pursuant to the Asset Sale Offer,  (ii) if the Company  appoints a depositary or
Paying Agent,  deposit with such depositary or Paying Agent money  sufficient to
pay  the  purchase  price  (including  all  accrued  interest  on the  purchased
Securities) of all Securities or portions thereof so accepted,  (iii) deliver or
cause the  depositary  or Paying Agent to deliver to the Trustee  Securities  so
accepted and (iv) deliver an Officers' Certificate identifying the Securities or
portions  thereof  accepted  for payment by the Company in  accordance  with the
terms of this Section 3.8. The depositary,  the Paying Agent or the Company,  as
the case may be,  promptly  shall mail or deliver  to each  tendering  Holder an
amount  equal to the  purchase  price  (including  all  accrued  interest on the
purchased  Securities) of the Securities tendered by such Holder and accepted by
the Company for purchase,  and the Trustee promptly shall  authenticate and mail
or deliver  to such  Holders a new  Security  equal in  principal  amount to any
unpurchased portion of the Security surrendered.  Any Securities not so accepted
promptly shall be mailed or delivered by the Company to the Holder thereof.  The
Company will publicly  announce the results of the Asset Sale Offer on the Asset
Sale Payment Date.


                                      -23-



     Other than as  specifically  provided  in this  Section  3.8,  any offer to
purchase  Securities  pursuant to this  Section 3.8 shall be made in  accordance
with the other provisions of this Indenture.

                                   ARTICLE 4.

the  Securities  on the  dates and in the  manner  provided  in the  Securities.

due if the Paying Agent,  other than the Company or a Subsidiary of the Company,
holds on that date money deposited by the Company  designated for and sufficient
to pay all principal, premium, if any, and interest then due.

     The Company  shall pay interest  (including  post-petition  interest in any
proceeding  under any Bankruptcy Law) on overdue  principal at the rate equal to
the interest rate on the Securities to the extent lawful;  it shall pay interest
on overdue  payments of premium,  if any, or installments  of interest  (without
regard to any applicable grace period) at the same rate to the extent lawful.

     On or prior to the  effective  date of this  Indenture,  the Trustee  shall
establish  a  segregated   non-interest-bearing  corporate  trust  account  (the
"Payment Account") maintained by the Trustee for the benefit of Holders in which
all amounts  paid in respect of the  Securities  will be held and from which the
Trustee shall make payments to the Holders in accordance with this Indenture and
the  Securities.  The Trustee and any Agent of the Trustee shall have  exclusive
control and sole right of withdrawal with respect to the Payment Account for the
purpose  of making  deposits  in and  withdrawals  from the  Payment  Account in

subordination to Senior Indebtedness in accordance with Article 10 hereof.

Section 4.2 Maintenance of Office or Agency

     The Company  will  maintain  an office or agency  where  Securities  may be
surrendered  for  registration  of transfer or  exchange  and where  notices and

Corporate Trust Office of the Trustee as such office or agency of the Company.

     The Company also from time to time may  designate one or more other offices
or agencies where the Securities may be presented or surrendered  for any or all
such purposes and from time to time may rescind such  designations.  The Company
will give  prompt  written  notice to the  Trustee  of any such  designation  or
rescission and of any change in the location of any such other office or agency.

Section 4.3 SEC Reports

     (a) The Company  shall  remain  subject to the  reporting  requirements  of
Section 13 or Section 15(d) of the Exchange Act and shall  continue to file with
the SEC such annual  reports and such  information,  documents and other reports
which are specified in Sections 13 and 15(d) of the Exchange Act.

Holders,  within 15 days  after it files  the same  with the SEC,  copies of its
annual reports and of the information, documents and other reports (or copies of
such  portions of any of the  foregoing as the SEC may by rules and  regulations
prescribe)  which the  Company or any  subsidiary  of the Company is required to

addresses  appearing in the register of Securities  maintained by the Registrar.

information as of the date of the most recent financial  statements in each such
report or comparable  information the amount available for payments  pursuant to
Section 4.7. The Trustee shall have no obligation to furnish such information to
the Holders unless instructed to do so by the Company or requested by a Holder.

Section 4.4 Compliance Certificate

     (a) 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 a
review  of the  activities  of the  Company  and  its  Subsidiaries  during  the
preceding  fiscal  year has been  made  under  the  supervision  of the  signing
Officers  with a view to  determining  whether the  Company has kept,  observed,
performed  and  fulfilled  its  obligations  under this  Indenture,  and further
stating,  as to each such Officer signing such certificate,  that to the best of
his knowledge  the Company has kept,  observed,  performed  and  fulfilled  each
covenant contained in this Indenture and is not in default in the performance or
observance  of any of the terms,  provisions  and  conditions  hereof  (or, if a
Default or Event of Default shall have occurred, describing all such Defaults or
Events of Default of which he may have  knowledge and what action the Company is
taking or proposes  to take with  respect  thereto)  and that to the best of his
knowledge  no event has  occurred  and remains in  existence  by reason of which
payments on account of the principal of or premium, if any, or interest, if any,
on the Securities  are prohibited or, if such event has occurred,  a description
of the event and what  action  the  Company is taking or  proposes  to take with
respect thereto.

     (b) So long as (i) not contrary to the then current  recommendations of the
American  Institute  of  Certified  Public  Accountants  or (ii)  the  Company's
independent  public  accountants  do not have in  effect a  policy,  of  general
applicability  with respect to their  clients,  that such  accountants  will not
prepare  statements  on the subjects  specified  below,  the year-end  financial
statements  delivered  pursuant to Section 4.3 shall be accompanied by a written
statement of the Company's  independent  public accountants (who shall be a firm
of established national reputation) that in making the examination necessary for
certification of such financial  statements  nothing has come to their attention
that would lead them to believe that the Company has violated any  provisions of
Article 4 or 5 or, if any such violation has occurred, specifying the nature and
period of existence thereof, it being understood that such accountants shall not
be liable  directly  or  indirectly  to any  Person  for any  failure  to obtain
knowledge of any such violation.

     (c) The Company,  so long as any of the  Securities are  outstanding,  will
deliver to the Trustee, forthwith upon any Officer becoming aware of any Default
or Event of Default under this Indenture,  an Officers'  Certificate  specifying
such  Default  or Event of  Default  and what  action  the  Company is taking or
proposes to take with respect thereto.

Section 4.5 Corporate Existence, Taxes, etc.

     Subject to the  provisions of Section 5.1, the Company shall do or cause to
be done all things  necessary  to preserve and keep in full force and effect its
rights (charter and statutory), licenses and franchises; provided, however, that
the Company shall not be required to preserve any such right or franchise if the
Board of Directors  shall determine that the  preservation  thereof is no longer
desirable  in the conduct of the business of the Company and the loss thereof is
not disadvantageous in any material respect to the Holders.

Section 4.6 Stay, Extension and Usury Laws

     The Company  covenants  (to the extent that it may  lawfully do so) that it
will not at any time insist  upon,  plead or in any manner  whatsoever  claim or
take the  benefit or  advantage  of any stay,  extension  or usury law  wherever
enacted,  now or at any time  hereafter in force,  that may affect the Company's
obligation  to pay the  Securities;  and the  Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
insofar as such law applies to the  Securities,  and covenants that it will not,
by resort to any such law,  hinder,  delay or impede the execution of any power,
right or remedy  herein  granted to the Trustee,  but will suffer and permit the
execution  of every such  power,  right or remedy as though no such law has been
enacted.

Section 4.7 Limitations on Restricted Payments

     The  Company  shall  not,  and shall not  permit  any of its  Subsidiaries,
directly or indirectly,  to make any  Restricted  Payment if at the time of such
Restricted Payment:

     (i) a Default or Event of Default  shall have occurred and be continuing or
shall occur as a consequence thereof;


    
                                  -25-


     (ii) after giving effect to the proposed Restricted Payment,  the amount of
such Restricted  Payment,  when added to the aggregate  amount of all Restricted
Payments  made after May 15, 1996,  exceeds the sum of (1) 50% of the  Company's
Consolidated  Net Income  accrued  during the period (taken as a single  period)
commencing  May 15, 1996, to and including the most recent fiscal  quarter ended
immediately prior to the date of such Restricted Payment and for which financial
results have been reported (or, if such aggregate  Consolidated Net Income shall
be a deficit,  minus 100% of such aggregate deficit);  (2) the net cash proceeds
from the  issuance  and sale of the  Company's  (a)  Capital  Stock  that is not
Disqualified  Stock,  including net cash proceeds  received upon the exercise of
any  options  or  warrants  to  purchase  shares of  Capital  Stock  other  than
Disqualified  Stock  (other than to a  Subsidiary  of the  Company) and (b) debt
securities  or  other   securities   that  are  convertible  or  exercisable  or
exchangeable for such Capital Stock that is not Disqualified Stock and that have
been so converted or exercised or exchanged,  after May 15, 1996;  (3) aggregate
net cash  proceeds  received by the Company  after the date of the  Indenture as

Indebtedness under the Consolidated Coverage Ratio test in Section 4.9(a).

     Notwithstanding the foregoing, the provisions of this Section 4.7 shall not
prevent  the  following  Restricted  Payments  (provided,   however,  that  such
Restricted  Payments  shall be included for purposes of computing  the amount of
Restricted   Payments  previously  made  under  clause  (ii)  of  the  preceding
paragraph):  (x) the  payment of any  dividend  within 60 days after the date of
declaration  thereof  if the  payment  thereof  would  have  complied  with  the
limitations of this covenant on the date of declaration  and (y) the purchase of
stock held by officers,  directors or employees of the Company whose  employment
or term with the Company has been terminated or who have died or become disabled
in an aggregate amount not to exceed $5.0 million in any fiscal year.

Section 4.8 Limitations on Restrictions on Distributions from Subsidiaries

     The Company  shall not,  and shall not permit any of its  Subsidiaries  to,
create or otherwise cause or suffer to exist or become  effective any consensual
encumbrance or restriction  (other than encumbrances or restrictions  imposed by
law or by  judicial or  regulatory  action or by  provisions  in leases or other
agreements  that  restrict  the  assignability  thereof)  on the  ability of any
Subsidiary of the Company to (i) pay  dividends or make any other  distributions
on its Capital Stock or any other interest or participation  in, or measured by,
its  profits,  owned by the  Company  or any of its other  Subsidiaries,  or pay
interest on or principal of any  Indebtedness  owed to the Company or any of its
other  Subsidiaries,  (ii) make loans or  advances  to the Company or any of its
other  Subsidiaries  or (iii)  transfer any of its  properties  or assets to the
Company  or  any  of  its  other   Subsidiaries,   except  for  encumbrances  or
restrictions  existing  under or by reason of (a)  applicable  law, (b) Existing
Indebtedness,  (c) any restrictions under any agreement  evidencing any Acquired
Indebtedness that was permitted to be incurred pursuant to Section 4.9, provided
that such  restrictions and encumbrances  only apply to assets that were subject
to such restrictions and encumbrances prior to the acquisition of such assets by
the Company or its  Subsidiaries,  (d)  restrictions or  encumbrances  replacing
those  permitted  by clause  (b) or (c)  which,  taken as a whole,  are not more
restrictive, (e) this Indenture, (f) any restrictions or encumbrances arising in
connection with  Refinancing  Indebtedness,  provided that any  restrictions and
encumbrances  of the type  described  in this  Section 4.8 that arise under such
Refinancing  Indebtedness are not, taken as a whole, more restrictive than those
under the agreement  creating or evidencing the  Indebtedness  being refunded or
refinanced,  (g) any  restrictions  with respect to a Subsidiary  of the Company
imposed  pursuant to an  agreement  that has been  entered  into for the sale or
other  disposition of all or substantially all of the Capital Stock or assets of
such Subsidiary,  (h) any agreement restricting the sale or other disposition of
property securing Indebtedness if such agreement does not expressly restrict the
ability  of a  Subsidiary  of the  Company  to pay  dividends  or make  loans or
advances  and (i)  customary  restrictions  in  purchase  money  debt or  leases
relating to the property covered thereby.

Section 4.9       Limitations on Additional Indebtedness

     (a) After the date hereof,  the Company shall not, and shall not permit any
of its Subsidiaries to, directly or indirectly,  create,  incur, issue,  assume,
guarantee,  extend the maturity of, or otherwise  become  liable with respect to
(collectively,   "incur"),  any  Indebtedness  (including,  without  limitation,
Acquired  Indebtedness),  unless  after giving  effect  thereto,  the  Company's
Consolidated Coverage Ratio on the date thereof would be at least:

          (i) 2.00 to 1, if such date is on or prior to March 31, 1998,


                                      -26-

          (ii) 2.25 to 1, if such date is after  March 31,  1998 and on or prior
     to March 31, 1999, and

          (iii) 2.50 to 1, if such date is after March 31, 1999,

in each  case  determined  on a pro  forma  basis as if the  incurrence  of such
additional  Indebtedness and the application of the net proceeds therefrom,  had
occurred at the  beginning  of the  four-quarter  period used to  calculate  the
Company's Consolidated Coverage Ratio.

     (b) Notwithstanding the foregoing: (a) the Company and its Subsidiaries may
(i) incur  Indebtedness under one or more Credit Facilities not to exceed $700.0
million at any one time outstanding; (ii) incur Refinancing Indebtedness;  (iii)
incur any  Indebtedness of the Company to any Wholly Owned  Subsidiary or of any
Subsidiary  to the  Company or to any Wholly  Owned  Subsidiary;  (iv) incur any
Indebtedness  evidenced  by  letters  of credit  which are used in the  ordinary
course of  business  of the  Company  and its  Subsidiaries  to secure  workers'
compensation  and other insurance  coverages;  and (v) incur  Capitalized  Lease
Obligations  of the  Company  and  its  Subsidiaries  such  that  the  aggregate
principal  amount  of  Capitalized  Lease  Obligations  of the  Company  and its
Subsidiaries then  outstanding,  when added to the Capitalized Lease Obligations
to be incurred,  does not exceed 5% of Consolidated Tangible Assets; and (b) the
Company  and its  Subsidiaries  may  incur  additional  Indebtedness  (including
additional  Indebtedness  under any Credit  Facility  that is designated in such
Credit Facility as incurred under this clause (b)),  provided that the aggregate
principal  amount of any such  additional  Indebtedness  outstanding  under this
clause (b) at any time,  together  with the aggregate  liquidation  value of any
outstanding  Preferred  Stock  issued by a Subsidiary  of the Company,  does not
exceed $75.0 million.

     No  Subsidiary  of the Company  shall  Guarantee  any  Indebtedness  of the
Company (including by way of a pledge of assets) that is subordinate in right of
payment to any Senior  Indebtedness  unless such  Subsidiary also guarantees the
Securities  and waives,  and will not claim or take  advantage of, any rights of
reimbursement,  indemnity or subrogation  against the Company as a result of any
payment by such Subsidiary under its Guarantee of the Securities.  If such other
Indebtedness  of the  Company  is (1)  pari  passu  with  the  Securities,  such
Guarantee of such pari passu  Indebtedness shall be pari passu with or expressly
subordinated to such Guarantee of the Securities,  or (2)  subordinated in right
of payment to the Securities,  such Guarantee of such subordinated  Indebtedness
shall be expressly subordinated to such Guarantee of the Securities, at least to
the extent that such subordinated  Indebtedness is subordinated or junior to the
Securities.  Notwithstanding the foregoing, any Guarantee of the Securities by a
Subsidiary   of  the  Company  may  provide  by  its  terms  that  it  shall  be
automatically  and  unconditionally  released and discharged upon the release or
discharge of the Guarantee  which  resulted in the creation of such Guarantee of
the Securities, except a discharge or release by or as a result of payment under
such  Guarantee of such other  Indebtedness  or if any other  Guarantee of other
Indebtedness is outstanding.

Section 4.10 Change in Control

     (a)  Following the  occurrence  of any Change in Control,  each Holder will
have the right, at such Holder's option, to require that the Company purchase (a
"Change  in Control  Repurchase"),  and upon the  exercise  of such  right,  the
Company shall, subject to the provisions of Section 10.3 hereof,  purchase,  all
or any part of such Holder's  Securities on a date (the "Repurchase  Date") that
is no  earlier  than 30 days nor later  than 60 days after the date on which the
Company  gives  notice  of a Change in  Control  as  provided  in (b) below at a
purchase  price  equal  to  101%  of  the  aggregate  principal  amount  of  the
Securities,  plus accrued and unpaid interest thereon, if any, to the Repurchase
Date.

     (b) Within 30 days after any Change in Control, the Company (with notice to
the Trustee),  or the Trustee at the Company's request, will mail or cause to be
mailed  to all  Holders  on the date of the  Change  in  Control a notice of the
occurrence  of such Change in Control and of the  Holders'  rights  arising as a
result  thereof.  Such  notice,  which  shall  govern the terms of the Change in
Control Repurchase, shall state:

          (1) that a Change in Control has occurred and that such Holder has the
     right to require the Company to  repurchase  such  Holder's  Securities  in
     cash;

          (2) the  Repurchase  Date (which  will be no earlier  than 30 days nor
     later than 60 days from the date such notice is mailed);


                                      -27-


          (3) the purchase price for the repurchase;

          (4) the date by which the repurchase right must be exercised; and

          (5) the instructions  determined by the Company,  consistent with this
     Section  4.10,  that a Holder must  follow in order to have its  Securities
     repurchased.

     (c) To exercise a repurchase  right,  a Holder shall deliver to the Company
(or a depositary  or Paying Agent  designated by the Company for such purpose in
the notice referred to in (b) above),  on or before the close of business on the
Repurchase Date, the Security or Securities with respect to which the repurchase
right is being  exercised,  duly endorsed for transfer to the Company,  with the
form  entitled  "Option  of Holder to Elect  Purchase"  on the  reverse  of each
Security so delivered  completed.  Holders  shall be entitled to withdraw  their
election if the Company (or the  depositary  or Paying Agent  designated  by the
Company for the purpose of receiving  such  election)  receives,  not later than
five Business Days prior to the Repurchase  Date, a telegram,  telex,  facsimile
transmission  or letter  setting  forth the name of the  Holder,  the  principal
amount of the Security or  Securities  the Holder  delivered  for purchase and a
statement that such Holder is withdrawing  its election to the have the Security
or Securities purchased.

     (d) In the event a repurchase  right shall be exercised in accordance  with
the terms  hereof,  subject to  Article  10, the  Company  shall on or  promptly
following  the  Repurchase  Date pay or  cause to be paid in cash to the  Holder
thereof  the  repurchase  price of the  Security or  Securities  as to which the
repurchase  right has been exercised.  In the event that the repurchase right is
exercised with respect to less than the entire principal amount of a surrendered
Security,  the Company  shall execute and deliver to the Trustee and the Trustee
shall  authenticate  for  issuance  in the name of the Holder a new  Security or
Securities in the aggregate  principal  amount of the  unrepurchased  portion of
such surrendered security.

     (e) If the Repurchase Date is on or before an Interest  Payment Date and on
or after the  related  record  date,  any  interest  accrued  and  unpaid to the
Repurchase  Date  will be paid to the  Person  in  whose  name the  Security  is
registered  at the close of  business  on such record  date,  and no  additional
interest will be payable to Holders who exercise their repurchase right pursuant
to this Section 4.10.

     (f) Any Change in Control  Repurchase shall be conducted in compliance with
applicable  tender offer rules,  including Section 14(e) of the Exchange Act and
Rule 14(e)(1)  thereunder.  The Change in Control Repurchase may not be modified
or conditioned by the Company in any manner.

Section 4.11 Limitations on Asset Sales

     The Company  shall not,  and shall not permit any of its  Subsidiaries  to,
consummate  any Asset Sale  unless (i) the Company or its  Subsidiaries  receive
consideration  at the time of such Asset Sale at least  equal to the fair market
value of the assets or Capital Stock  included in such Asset Sale (as determined
in good faith by the Board of Directors, whose determination shall be conclusive
and  evidenced  by a board  resolution)  and  (ii)  not  less  than  50% of such
consideration  is in the form of cash or Cash  Equivalents  (provided,  however,
that this clause (ii) shall not be applicable to a transaction  involving assets
acquired and  designated as held for sale,  which assets  represent in aggregate
since the date of the Indenture 5% or less of the net tangible assets previously
acquired by the Company or a Subsidiary  pursuant to acquisitions since the date
of the  Indenture  and  which  assets  are  disposed  of no later  than one year
following  their  initial  acquisition).  The Net Proceeds of Asset Sales shall,
within 360 days of receipt  thereof,  (a) be reinvested in the lines of business
of the Company or any of its Subsidiaries  immediately prior to such investment;
(b) be applied to the  payment of the  principal  of, and  interest  on,  Senior
Indebtedness;  (c) be  utilized  to make  any  Investment  in any  other  Person
permitted  under this  Indenture;  or (d) be applied to an offer (an "Asset Sale
Offer") to purchase  outstanding  Securities.  In any such Asset Sale Offer, the
Company  shall offer to purchase  Securities  on a pro rata basis  (unless  such
method is otherwise  prohibited,  in which case the  Securities  to be purchased
shall be selected by lot, with such adjustments as may be deemed  appropriate by
the  Company so that only  Securities  in  denominations  of $1,000 or  integral
multiples  thereof  shall be  purchased,  or in such other manner as the Trustee
shall  deem  fair  and  equitable),  at a  purchase  price  equal to 100% of the
aggregate  principal amount of the Securities,  plus accrued and unpaid interest
to the date of purchase,  in the manner set forth in this  Indenture.  Any Asset
Sale Offer will be conducted in compliance with  applicable  tender offer rules,
including Section 14(e) of the Exchange Act and Rule 14e-1  thereunder.  Any Net
Proceeds remaining  immediately after the completion of any Asset Sale Offer may
be used by the Company or its Subsidiaries for any purpose not inconsistent with
the other provisions of this Indenture.


                                      -28-



     Notwithstanding the provisions of the immediately preceding paragraph,  the
Company and its  Subsidiaries  may, in the ordinary  course of business  (or, if
otherwise than in the ordinary  course of business,  upon receipt of a favorable
written opinion from an independent  financial advisor of national reputation as
to the fairness from a financial point of view to the Company or such Subsidiary
of the  proposed  transaction),  exchange  all  or a  portion  of its  property,
businesses or assets for  property,  businesses or assets that, or Capital Stock
of a Person all or  substantially  all of whose assets,  are of a type used in a
healthcare related business,  or a combination of any such property,  businesses
or  assets,  or  Capital  Stock of such a Person  and cash or Cash  Equivalents;
provided that (i) there shall not exist immediately prior or subsequent  thereto
a Default or an Event of Default,  (ii) a majority of the disinterested  members
of the Board of Directors of the Company shall have approved a resolution of the
Board of Directors that such exchange is fair to the Company or such Subsidiary,
as the case may be, and (iii) any cash or Cash Equivalents  received pursuant to
any such exchange  shall be applied in the manner  applicable to Net Proceeds of
Asset Sales as set forth pursuant to the provisions of the immediately preceding
paragraph; and provided, further, that any Capital Stock of a Person received in
such an  exchange  pursuant  to this  paragraph  shall be owned  directly by the
Company or a Subsidiary of the Company and, when combined with the Capital Stock
of such person already owned by the Company and its  Subsidiaries,  shall result
in such Person becoming a Wholly Owned Subsidiary of the Company.

Section 4.12 Limitations on Transactions with Affiliates

     Neither  the  Company  nor any of its  Subsidiaries  shall  make any  loan,
advance,  guarantee or capital  contribution to, or for the benefit of, or sell,
lease,  transfer or otherwise  dispose of any of its properties or assets to, or
for the benefit of, or purchase or lease any property or assets  from,  or enter
into or amend any contract,  agreement or understanding with, or for the benefit
of, any  Affiliate of the Company or any of its  Subsidiaries  or any Person (or
any  Affiliate of such Person)  holding 10% or more of the Common  Equity of the
Company or any of its Subsidiaries (each an "Affiliate  Transaction") unless (i)
such  Affiliate   Transactions   are  between  or  among  the  Company  and  its
Subsidiaries;  (ii) such Affiliate  Transactions  are in the ordinary  course of
business and consistent with past practice; or (iii) the terms of such Affiliate
Transactions are fair and reasonable to the Company or such  Subsidiary,  as the
case may be, and are at least as  favorable as the terms which could be obtained
by the  Company  or  such  Subsidiary,  as the  case  may  be,  in a  comparable
transaction made on an arm's-length basis between  unaffiliated  parties. In the
event of any transaction or series of transactions  occurring  subsequent to the
date of this  Indenture  with an Affiliate of the Company which is not permitted
under  clauses  (i) or (ii) above and  involves in excess of $5.0  million,  the
terms  of  such  transaction   shall  be  in  writing  and  a  majority  of  the
disinterested  members of the Board of Directors  shall by resolution  determine
that such business or  transaction  meets the criteria set forth in clause (iii)
above.

Section 4.13 Limitations on Liens

     The Company shall not, and shall not permit any Subsidiary to,  directly or
indirectly,  create,  incur  or  affirm  any  Lien  of  any  kind  securing  any
Indebtedness  which is pari  passu or  subordinate  in right of  payment  to the
Securities (including any assumption,  guarantee or other liability with respect
thereto  by  any  Subsidiary)  upon  any  property  or  assets   (including  any
intercompany notes) of the Company or any Subsidiary owned on the date hereof or
hereafter  acquired,  or any income or profits therefrom,  unless the Securities
are directly  secured  equally and ratably with (or, in the case of subordinated
Indebtedness,  prior or senior thereto,  with the same relative  priority as the
Securities  shall  have with  respect  to such  subordinated  Indebtedness)  the
obligation  or liability  secured by such Lien except for Liens (A) securing any
Indebtedness which became Indebtedness pursuant to a transaction permitted under
Section 5.1 hereof or securing Acquired  Indebtedness  which, in each case, were
created prior to (and not created in connection  with, or in  contemplation  of)
the incurrence of such pari passu  Indebtedness or subordinated  Indebtedness by
the Company or any  Subsidiary  and which  Indebtedness  is permitted  under the
provisions  of Section 5.1 hereof,  (B)  securing any  Indebtedness  incurred in
connection with any refinancing,  renewal,  substitutions or replacements of any
such  Indebtedness  described  in  clause  (A) or (C)  created  in  favor of the
Company;  provided,  however,  that in the case of clauses (A) and (B), any such
Lien only  extends to the assets that were  subject to such Lien  securing  such
Indebtedness   prior  to  the  related   acquisition   by  the  Company  or  its
Subsidiaries.


                                      -29-


Section 4.14 Limitations on Subsidiary Preferred Stock

     The Company shall not permit any of its Subsidiaries to issue any Preferred
Stock  (other than to the Company or a Wholly  Owned  Subsidiary)  or permit any
Person (other than the Company or a Wholly Owned  Subsidiary) to own or hold any
interest in any Preferred  Stock of any such  Subsidiary  (other than  Preferred
Stock issued prior to the date of this  Indenture),  unless the Subsidiary would
be permitted to incur  Indebtedness  pursuant to the  provisions  of Section 4.9
hereof in the  aggregate  principal  amount equal to the  aggregate  liquidation
value of such Preferred Stock.

Section 4.15 Limitations on Certain Other Subordinated Indebtedness

     The  Company  shall  not  create,  incur,  assume  or  suffer  to exist any
Indebtedness that is subordinate in right of payment to any Senior  Indebtedness
unless such Indebtedness by its terms or the terms of the instrument creating or
evidencing  such  Indebtedness  is  subordinate in right of payment to, or ranks
pari passu with, the Securities.

Section 4.16 Limitations on Subsidiaries and Unrestricted Subsidiaries

     The Company may, by written notice to the Trustee, designate any Subsidiary
(including a newly acquired or a newly formed  Subsidiary) to be an Unrestricted
Subsidiary;  provided,  however,  that (i) no Default or Event of Default  shall
have occurred and be continuing or would arise therefrom, (ii) such designation,
when  considered as an Investment as described in the next sentence,  is at that
time permitted  under the covenant  described under Section 4.7 hereof and (iii)
immediately  after giving  effect to such  designation,  the Company could incur
$1.00 of additional  Indebtedness  pursuant to clause (a) of Section 4.9 hereof.
For purposes of Section 4.7 hereof,  (i) an "Investment" shall be deemed to have
been made at the time any Subsidiary is designated as an Unrestricted Subsidiary
in an amount  (proportionate to the Company's percentage Equity Interest in such
Subsidiary)  equal to the net  worth of such  Subsidiary  at the time  that such
Subsidiary  is designated as an  Unrestricted  Subsidiary;  (ii) at any date the
aggregate  amount of all Restricted  Payments made as Investments  since May 15,
1996 shall exclude and be reduced by an amount  (proportionate  to the Company's
percentage  Equity  Interest in such  Subsidiary)  equal to the net worth of any
Unrestricted   Subsidiary  from  and  after  the  date  that  such  Unrestricted
Subsidiary is designated a  Subsidiary,  not to exceed,  in the case of any such
redesignation  of an  Unrestricted  Subsidiary  as a  Subsidiary,  the amount of
Investments  previously  made  by the  Company  and  its  Subsidiaries  in  such
Unrestricted  Subsidiary (in the case of either clauses (i) or (ii) above,  "net
worth" to be  calculated  based upon the fair market value of the assets of such
Subsidiary  as of  any  such  date  of  designation);  and  (iii)  any  property
transferred to or from an  Unrestricted  Subsidiary  shall be valued at its fair
market  value  at the  time of such  transfer.  As of the  date of the  original
issuance of the Securities, there shall exist no Unrestricted Subsidiaries.

     Notwithstanding  the  foregoing,  the Board of Directors of the Company may
not designate any Subsidiary of the Company to be an Unrestricted Subsidiary if,
after  such  designation,  (a) the  Company  or any  Subsidiary  of the  Company
provides  credit  support  for, or a  guarantee  of, any  Indebtedness  or other
obligation   (contingent  or  otherwise)  of  such  Subsidiary   (including  any
undertaking, agreement or instrument evidencing such Indebtedness or obligation)
or is otherwise subject to recourse or obligated  thereunder or therefor,  (b) a
default with respect to any Indebtedness of such Subsidiary (including any right
which the  holders  thereof may have to take  enforcement  action  against  such
Subsidiary) would permit (upon notice,  lapse of time or both) any holder of any
other  Indebtedness of the Company or any Subsidiary of the Company to declare a
default  on  such  other  Indebtedness  or  cause  the  payment  thereof  to  be
accelerated or payable prior to its final scheduled maturity (whether or not any
such default had occurred or was continuing as of the time of such designation),
(c) such Subsidiary  owns any Equity  Interests in, or owns or holds any Lien on
any property of, any  Subsidiary  which is not a Subsidiary of the Subsidiary to
be so designated, (d) such Subsidiary has any contract,  arrangement,  agreement
or  understanding  with the Company,  or any Subsidiary of the Company,  whether
written or oral, other than a transaction  having terms no less favorable to the
Company or such  Subsidiary of the Company than those which might be obtained at
the time from persons who are not Affiliates of the Company,  or (e) the Company
or any  Subsidiary of the Company has any obligation to subscribe for any Equity
Interest  in such  Subsidiary  or to  maintain  or  preserve  such  Subsidiary's
financial  condition or to cause such Subsidiary to achieve  specified levels of
operating results.

                                   SUCCESSORS

Section 5.1 Limitations on Mergers and Consolidations

     The Company shall not  consolidate  or merge with or into, or sell,  lease,
convey or otherwise dispose of all or substantially all of its assets, or assign
any of its obligations hereunder or under the Securities, to any Person unless:

     (i) the Person  formed by or  surviving  such  consolidation  or merger (if
other  than  the  Company),  or  to  which  sale,  lease,  conveyance  or  other
disposition or assignment shall be made  (collectively,  the "Successor"),  is a
corporation  organized  and existing  under the laws of the United States or any
State  thereof  or the  District  of  Columbia,  and the  Successor  assumes  by
supplemental  indenture  in a  form  satisfactory  to  the  Trustee  all  of the
obligations of the Company hereunder and under the Securities;

     (ii)  immediately  after giving effect to such  transaction,  no Default or
Event of Default shall have occurred and be continuing;

     (iii)  immediately  after giving effect to such  transaction and the use of
any net proceeds  therefrom on a pro forma basis,  the Consolidated Net Worth of
the Company or the Successor, as the case may be, would be at least equal to the
Consolidated Net Worth of the Company immediately prior to such transaction; and

     (iv) the  Consolidated  Coverage Ratio of the Company or the Successor,  as
the case may be, immediately after giving effect to such transaction, would on a
pro forma basis be such that the Company or the  Successor,  as the case may be,
would be  entitled  to incur at least $1 of  additional  Indebtedness  under the
Consolidated Coverage Ratio test in Section 4.9(a).

                  The  Company  shall  deliver  to  the  Trustee  prior  to  the
consummation  of  the  proposed  transaction  an  Officers'  Certificate  to the
foregoing effect and an Opinion of Counsel stating that the proposed transaction
and such supplemental indenture comply with this Indenture.

Section 5.2 Successor Corporation Substituted

     Upon any consolidation or merger,  or any sale, lease,  conveyance or other
disposition  of all or  substantially  all of the  assets of the  Company or any
assignment  of  its  obligations  under  this  Indenture  or the  Securities  in
accordance with Section 5.1, the Successor formed by such  consolidation or into
or with which the Company is merged or to which such sale, lease,  conveyance or
other  disposition  or assignment  is made shall succeed to, and be  substituted
for, and may exercise every right and power of, the Company under this Indenture
with the same effect as if such  Successor has been named as the Company  herein
and the predecessor  Company, in the case of a sale, lease,  conveyance or other
disposition or  assignment,  shall be released from all  obligations  under this
Indenture and the Securities.


                                   ARTICLE 6.

                              DEFAULTS AND REMEDIES

Section 6.1 Events of Default

     An "Event of Default" occurs if:

     (1) the Company defaults in the payment of the principal of, or any premium
on,  any  Security  when the same  becomes  due and  payable,  whether at Stated
Maturity, upon redemption, upon acceleration or otherwise;


                                      -31-



     (2) the Company  defaults in the payment of interest on any  Security  when
the same  becomes due and payable and the Default  continues  for a period of 30
days (even if such payment is prohibited by Article 10 hereof);

     (3) the Company fails to comply with any of its agreements or covenants in,
or provisions of, the Securities or this Indenture  (other than a default in the
performance  or breach of a covenant  or  agreement  specifically  addressed  in
clause (1) or (2) of this Section) and such failure continues for the period and
after the notice specified below;

     (4) any  acceleration of the maturity of Indebtedness of the Company or its
Subsidiaries having in the aggregate an outstanding principal amount of at least
$10.0  million or a failure  to pay such  Indebtedness  at its Stated  Maturity;
provided  that such  acceleration  or failure to pay is not cured within 10 days
after such acceleration or failure to pay;

     (5) the  Company  or any of its  Significant  Subsidiaries  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 all or
     substantially all of its property, or

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

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

          (a)  is for  relief  against  the  Company  or any of its  Significant
     Subsidiaries as debtor in an involuntary case,

          (b)  appoints a  Custodian  of the  Company or any of its  Significant
     Subsidiaries or a Custodian for all or substantially all of the property of
     the Company or any of its Significant Subsidiaries, or

          (c) orders the  liquidation  of the Company or any of its  Significant
     Subsidiaries,

     and the order or decree remains unstayed and in effect for 60 days.

     The term "Custodian" means any receiver,  trustee, assignee,  liquidator or
similar official under any Bankruptcy Law.

     The Trustee  shall not be deemed to know of a Default  unless it has actual
knowledge  of such  Default or  receives  written  notice of such  Default  with
specific reference to such Default.

     A Default  under  clause (3) is not an Event of Default  until the  Trustee
notifies  the  Company,  or the Holders of at least 25% in  aggregate  principal
amount of the then outstanding Securities notify the Company and the Trustee, of
the  Default  and the  Company  does not cure the  Default  within 45 days after
receipt of the notice.  The notice must specify the  Default,  demand that it be
remedied and state that the notice is a "Notice of Default."


                                      -32-



Section 6.2 Acceleration

     If an Event of Default  (other than an Event of Default with respect to the
Company specified in clause (5) or (6) of Section 6.1) occurs and is continuing,
the Trustee by written notice to the Company,  or the Holders of at least 25% in
aggregate principal amount of the then outstanding  Securities by written notice
to the Company and the Trustee, may declare all Securities to be due and payable
immediately.   Upon  such  declaration  the  amounts  due  and  payable  on  the
Securities,  as determined in the next  succeeding  paragraph,  shall be due and
payable  immediately.  If an  Event  of  Default  with  respect  to the  Company
specified in clause (5) or (6) of Section 6.1 occurs,  such an amount shall ipso
facto become and be immediately due and payable without any declaration,  notice
or other act on the part of the Trustee or any Holder. The Holders of a majority
in aggregate  principal  amount of the then  outstanding  Securities  by written
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  (except  nonpayment of principal  of, or premium,  if any, or
interest  on the  Securities  or that  resulted  from a failure  to comply  with
Section 4.10) have been cured or waived.

     In the event that the maturity of the Securities is accelerated pursuant to
this Section 6.2,  100% of the  principal  amount  thereof and premium,  if any,
shall become due and payable  plus accrued  interest to the date of payment plus
interest on defaulted interest to the extent provided herein.

Section 6.3 Other Remedies

     If an Event of Default occurs and is continuing, the Trustee may pursue any
available remedy to collect the payment of the principal of, or premium, if any,
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 Holder 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.  All remedies are cumulative
to the extent permitted by law.

Section 6.4 Waiver of Past Defaults

     The  Holders  of a  majority  in  aggregate  principal  amount  of the then
outstanding Securities by notice to the Trustee may waive an existing Default or
Event of Default and its consequences,  except a continuing  Default or Event of
Default in the payment of the principal  of, or premium,  if any, or interest on
any Security or in respect of a provision  under this Indenture  which cannot be
modified  or amended  without the  consent of the Holder of each  Security  then
outstanding.  Upon any such waiver,  such Default shall cease to exist,  and any
Event of Default arising  therefrom shall be deemed to have been cured for every
purpose of this Indenture;  but no such waiver shall extend to any subsequent or
other  Default  or Event of  Default  or impair  any right or remedy  consequent
thereon.

Section 6.5 Control by Majority

     The  Holders  of a  majority  in  aggregate  principal  amount  of the then
outstanding  Securities may direct the time,  method and place of conducting any
proceeding  for any remedy  available to the Trustee or exercising  any trust or
power conferred on it.  However,  the Trustee may refuse to follow any direction
that conflicts with law or this  Indenture,  that the Trustee  determines may be
unduly  prejudicial  to the rights of other  Holders,  or that may  involve  the
Trustee in personal liability, in each case as determined by the Trustee.

Section 6.6 Limitations on Suits

     A  Holder  may  pursue a  remedy  with  respect  to this  Indenture  or the
Securities only if:

     (1) the Holder gives to the Trustee written notice of a continuing Event of
Default;

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


                                      -33-


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

     (4) the  Trustee  does not  comply  with the  request  within 60 days after
receipt of the request and the offer of indemnity; and

     (5) during  such  60-day  period the  Holders  of a majority  in  aggregate
principal  amount of the then  outstanding  Securities do not give the Trustee a
direction inconsistent with the request.

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

Section 6.7 Rights of Holders to Receive Payment

     Notwithstanding  any other  provision of this  Indenture,  the right of any
Holder of a Security  to receive  payment of  principal,  premium,  if any,  and
interest on the Security,  on or after the respective due dates expressed in the
Security,  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
the Holder.

Section 6.8 Collection Suit by Trustee

     If an Event of Default  specified  in  Section  6.1(1) or (2) occurs and is
continuing, the Trustee is authorized to recover judgment in its own name and as
trustee of an express  trust against the Company for the amount of principal of,
premium, if any, and interest remaining unpaid on the Securities,  determined in
accordance with Section 6.2, and interest on overdue  principal and premium,  if
any, and, to the extent lawful,  interest on overdue  installments  of interest,
and such further  amount as shall be  sufficient to cover the costs and expenses
of collection,  including the reasonable compensation,  expenses,  disbursements
and advances of the Trustee, its agents and counsel.

Section 6.9 Trustee May File Proofs of Claim

     The Trustee is  authorized to 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  (including  any  claim  for  the  reasonable  compensation,   expenses,
disbursements  and  advances of the  Trustee,  its agents and  counsel)  and the
Holders  allowed  in any  judicial  proceedings  relative  to the  Company,  its
creditors  or its  property  and shall be  entitled  and  empowered  to collect,
receive and distribute any money or other property payable or deliverable on any
such  claims  and any  Custodian  in any  such  judicial  proceeding  is  hereby
authorized by each Holder to make such 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  to it  for  the  reasonable
compensation,  expenses,  disbursements and advances of the Trustee,  its agents
and counsel,  and any other  amounts due the Trustee  under  Section 7.6. To the
extent that the payment of any such  compensation,  expenses,  disbursements and
advances of the Trustee,  its agents and counsel,  and any other amounts due the
Trustee  under  Section 7.6 out of the estate in any such  proceeding,  shall be
denied  for any  reason,  payment of the same shall be secured by a Lien on, and
shall be paid out of, any and all distributions,  dividends,  money,  securities
and other  properties  which the  Holders of the  Securities  may be entitled to
receive  in  such  proceeding  whether  in  liquidation  or  under  any  plan of
reorganization  or arrangement or otherwise.  Nothing herein  contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any  Holder any plan of  reorganization,  arrangement,  adjustment  or
composition  affecting the Securities or the rights of any Holder thereof, or to
authorize  the Trustee to vote in respect of the claim of any Holder in any such
proceeding;  provided,  however, that the Trustee may, on behalf of the Holders,
vote for the election of a trustee (or similar  official) in bankruptcy  and may
be a member of the creditors' committee.

Section 6.10 Priorities

     If the Trustee  collects any money pursuant to this Article 6, it shall pay
out the money in the following order:

     First: to the Trustee for amounts due under Section 7.6;

     Second:  to  Holders  for  amounts  due and  unpaid on the  Securities  for
principal,  premium,  if any,  and


                                      -34-


interest,  ratably, without preference or priority of any kind, according to the
amounts due and payable on the Securities for  principal,  premium,  if any, and
interest, respectively; and

     Third: to the Company.

     The  Trustee  may fix a record  date and  payment  date for any  payment to
Holders pursuant to this Article.

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 a
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 6.11
does not apply to a suit by the Trustee,  a suit by a Holder pursuant to Section
6.7 or a suit by  Holders  of more  than  10% in  principal  amount  of the then
outstanding Securities.


                                   ARTICLE 7.

                                     TRUSTEE

Section 7.1 Duties of Trustee

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

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

          (a) the Trustee need  perform only those duties that are  specifically
     set forth in this  Indenture  and no others,  and no implied  covenants  or
     obligations shall be read into this Indenture against the Trustee; and

          (b)  in the  absence  of  bad  faith  on its  part,  the  Trustee  may
     conclusively rely, as to the truth of the 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, on their face,  they appear to conform to the  requirements
     of this Indenture.

     (3) The Trustee may not be relieved from  liabilities for its own negligent
action, its own negligent failure to act, or its own willful misconduct,  except
that:

          (a) this  paragraph does not limit the effect of paragraph (2) of this
     Section;

          (b) 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

          (c) 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 6.5.

     (4) Whether or not therein  expressly so provided,  every provision of this
Indenture  that in any way relates to the Trustee is subject to paragraphs  (1),
(2), (3) and (5) of this Section 7.1.

     (5) No provision of this  Indenture  shall require the Trustee to expend or
risk its own funds or incur any liability. The Trustee may refuse to perform any
duty or exercise any right or power unless it receives indemnity satisfactory to
it against any loss, liability or expense.


                                      -35-


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

Section 7.2 Rights of Trustee

     (1) Subject to Section 7.1,  the Trustee may rely on any document  believed
by it to be genuine and to have been signed or presented  by the proper  Person,
and the Trustee need not investigate any fact or matter stated in the document.

     (2) Before the Trustee  acts or  refrains  from  acting,  it may require an
Officers' Certificate or an Opinion of Counsel or both. The Trustee shall not be
liable  for any action it takes or omits to take in good  faith in  reliance  on
such Officers'  Certificate or Opinion of Counsel.  The Trustee may consult with
counsel and the written  advice of such counsel or any Opinion of Counsel  shall
be full and  complete  authorization  and  protection  in  respect of any action
taken,  suffered  or  omitted  by it  hereunder  in good  faith and in  reliance
thereon.

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

     (4) 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 conferred upon it by this Indenture.

     (5) Unless otherwise  specifically provided in this Indenture,  any demand,
request,  direction or notice from the Company  shall be sufficient if signed by
an Officer of the Company.

Section 7.3 Individual Rights of Trustee

     The Trustee in its individual or any other capacity may become the owner or
pledgee of  Securities  and may  otherwise  deal with the  Company or any of its
Affiliates with the same rights it would have if it were not Trustee.  Any Agent
may do the same with like rights.

Section 7.4 Trustee's Disclaimer

     The Trustee makes no  representation as to the validity or adequacy of this
Indenture or the Securities or as to the Company's ability to pay the Securities
when and as due or  perform  its other  obligations  hereunder.  It shall not be
accountable  for the Company's  use of the proceeds  from the  Securities or any
money paid to the Company or upon the  Company's  direction  under any provision
hereof.  It shall not be  responsible  for the use or  application  of any money
received by any Paying Agent other than the Trustee. It shall not be responsible
for any  statement or recital  herein or any statement in the  Securities  other
than its certificate of authentication.

Section 7.5 Notice of Defaults

     If a Default or Event of  Default  occurs  and is  continuing  and if it is
known to the Trustee,  the Trustee shall mail to Holders a notice of the Default
or Event of  Default  within 90 days  after it  occurs.  Except in the case of a
Default or Event of Default in payment of the principal of, or premium,  if any,
or interest on any  Security or that  resulted  from a failure by the Company to
comply with  Section  4.10,  the Trustee may  withhold  the notice if it in good
faith determines that withholding the notice is in the interests of Holders.

Section 7.6 Compensation and Indemnity

     The  Company  shall  pay  to the  Trustee  from  time  to  time  reasonable
compensation  for its acceptance of this Indenture and services  hereunder.  The
Trustee's  compensation  shall not be  limited by any law on  compensation  of a
trustee of an express  trust.  The Company  shall  reimburse  the  Trustee  upon
request for all reasonable disbursements,  advances and expenses incurred by it.
Such  expenses  shall include the  reasonable  compensation,  disbursements  and
expenses of the Trustee's agents and counsel.


                                      -36-


     The Company shall indemnify the Trustee, its employees, officers, directors
and agents and any predecessor Trustee hereunder against any loss,  liability or
expense  incurred by it arising out of or in connection  with the  acceptance or
administration  of  its  duties  under  this  Indenture  or in  connection  with
enforcing  this  indemnification   provision,  the  offering  and  sale  of  the
Securities,  any act of  negligence or bad faith of the Company or of any of its
officers,  employees,  agents  or  licensees,  except  as set  forth in the next
paragraph.  The Trustee promptly shall notify the Company of any claim for which
it may seek indemnity.  The Company shall defend the claim and the Trustee shall
cooperate in the defense.  The Trustee may have separate counsel and the Company
shall pay the reasonable fees and expenses of such counsel. The Company need not
pay for any  settlement  made without its consent,  which  consent  shall not be
unreasonably withheld.

     The Company need not reimburse any expense or indemnify against any loss or
liability incurred by the Trustee through negligence or bad faith.

     To secure the  Company's  payment  obligations  in this  Section  7.6,  the
Trustee shall have a Lien prior to the  Securities on all money or property held
or  collected  by the Trustee,  except that held in trust to pay  principal  of,
premium, if any, and interest on particular Securities.  Such Lien shall survive
the satisfaction and discharge of this Indenture.

     When the  Trustee  incurs  expenses or renders  services  after an Event of
Default  specified  in  Section  6.1(5)  or (6)  occurs,  the  expenses  and the
compensation   for  the  services  are  intended  to   constitute   expenses  of
administration under any Bankruptcy Law.

Section 7.7 Replacement of Trustee

     A  resignation  or removal of the  Trustee and  appointment  of a successor
Trustee shall become effective only upon the successor  Trustee's  acceptance of
appointment as provided in this Section.

     The Trustee may resign and be discharged  from the trust hereby  created by
so notifying the Company.  The Holders of a majority in principal  amount of the
then  outstanding  Securities may remove the Trustee by so notifying the Trustee
and the Company. The Company may remove the Trustee if:

          (1) the Trustee fails to comply with Section 310(b) of the TIA;

          (2) the Trustee is adjudged a bankrupt or an insolvent or an order for
     relief is entered with respect to the Trustee under any Bankruptcy Law;

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

          (4) the Trustee becomes incapable of acting.

     If the Trustee  resigns or is removed or if a vacancy  exists in the office
of Trustee  for any  reason,  the  Company  shall  promptly  appoint a successor
Trustee.

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

     If the Trustee  fails to comply with Section 310 of the TIA, any Holder may
petition any court of competent  jurisdiction for the removal of the Trustee and
the appointment of 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 Holders. 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  7.6.
Notwithstanding  replacement  of the Trustee  pursuant to this  Section 7.7, the
Company's  obligations  under Section 7.6 shall  continue for the benefit of the
retiring Trustee.


                                      -37-


Section 7.8 Successor Trustee by Merger, etc.

     Subject to Section  7.9,  if the Trustee  consolidates,  merges or converts
into, or transfers all or substantially  all of its corporate trust business to,
another corporation,  the successor corporation without any further act shall be
the successor Trustee.

Section 7.9 Eligibility; Disqualification

     There  shall at all times be a Trustee  hereunder  which shall be a bank or
corporation  organized and doing business under the laws of the United States of
America,  any state  thereof or the District of Columbia  authorized  under such
laws to exercise  corporate  trustee  power,  shall be subject to supervision or
examination  by Federal or state (or the  District of  Columbia)  authority  and
shall have a combined  capital  and surplus of at least $50 million as set forth
in its most recent published annual report of condition.

     This Indenture  shall always have a Trustee who satisfies the  requirements
of TIAss.  310(a)(1) and 310(a)(2).  The Trustee is subject to TIAss. 310(b). If
at any time the  Trustee  shall  cease to be  eligible  in  accordance  with the
provisions of this Section,  it shall resign  immediately in the manner and with
the effect specified in Section 7.7.


                                   ARTICLE 8.

                             DISCHARGE OF INDENTURE

Section 8.1 Termination of Company's Obligations

     (a) This  Indenture  shall cease to be of further  effect  (except that the
Company's  obligations  under Section 7.6 and the  Trustee's and Paying  Agent's
obligations  under Section 8.3 shall  survive) when all  outstanding  Securities
theretofore  authenticated and issued have been delivered (other than destroyed,
lost or stolen  Securities  that have been  replaced or paid) to the Trustee for
cancellation and the Company has paid all sums payable  hereunder.  In addition,
the Company may elect to have either  paragraph  (b) or  paragraph  (c) below be
applied to the  outstanding  Securities  upon compliance with the conditions set
forth in paragraph (d).

     (b)  Upon  the  Company's  exercise  under  paragraph  (a)  of  the  option
applicable  to this  paragraph  (b),  the  Company  shall be deemed to have been
released and discharged  from its  obligations  with respect to the  outstanding
Securities   on  the  date  the   conditions   set  forth  below  are  satisfied
(hereinafter, "legal defeasance"). For this purpose, such legal defeasance means
that the  Company  shall  be  deemed  to have  paid and  discharged  the  entire
indebtedness  represented by the outstanding Securities,  which shall thereafter
be deemed to be  "outstanding"  only for the  purposes  of the  Sections  of and
matters  under this  Indenture  referred to in (i) and (ii)  below,  and to have
satisfied all its other  obligations  under such  Securities  and this Indenture
insofar as such Securities are concerned (and the Trustee, at the expense of the
Company,  shall execute proper instruments  acknowledging the same),  except for
the  following  which shall  survive  until  otherwise  terminated or discharged
hereunder: (i) the rights of Holders of outstanding Securities to receive solely
from the trust fund described in paragraph (d) below and as more fully set forth
in such paragraph, payments in respect of the principal of, premium, if any, and
interest on such  Securities  when such  payments  are due,  (ii) the  Company's
obligations  with respect to such  Securities  under  Sections 2.5, 2.6 and 4.2,
and, with respect to the Trustee,  under Section 7.6, (iii) the rights,  powers,
trusts,  duties and  immunities  of the Trustee  hereunder and (iv) this Section
8.1.  Subject to compliance  with this Section 8.1, the Company may exercise its
option under this paragraph (b) notwithstanding the prior exercise of its option
under paragraph (c) below with respect to the Securities.

     (c)  Upon  the  Company's  exercise  under  paragraph  (a)  of  the  option
applicable to this  paragraph  (c), the Company shall be released and discharged
from its obligations  under any covenant  contained in Article 5 and in Sections
4.3, 4.4 and 4.6 through 4.16 with respect to the outstanding  Securities on and
after the date the  conditions  set  forth  below  are  satisfied  (hereinafter,
"covenant defeasance"),  and the Securities shall thereafter be deemed to be not
"outstanding" for the purpose of any direction,  waiver,  consent or declaration
or act of Holders (and the  consequences of any thereof) in connection with such
covenants,  but shall continue to be deemed "outstanding" for all other purposes
hereunder.  For this purpose,  such covenant defeasance means that, with respect
to the  outstanding  Securities,  the  Company may omit to comply with and shall
have no liability in respect of any term,  condition or limitation  set forth in


                                      -38-


any such covenant,  whether  directly or indirectly,  by reason of any reference
elsewhere  herein to any such covenant or by reason of any reference in any such
covenant  to any  other  provision  herein  or in any  other  document  and such
omission to comply shall not  constitute a Default or an Event of Default  under
Section 6.1, but, except as specified above, the remainder of this Indenture and
such Securities shall be unaffected thereby.

     (d) The  following  shall be the  conditions to the  application  of either
paragraph (b) or (c) above to the outstanding Securities:

               (1) the  Company  has  irrevocably  deposited  in trust  with the
         Trustee or, at the option of the Trustee,  with a trustee  satisfactory
         to the Trustee and the Company under the terms of an irrevocable  trust
         agreement in form and substance satisfactory to the Trustee in its sole
         discretion,  money or U.S.  Government  Obligations  sufficient  to pay
         principal  of,  premium,  if any,  and  interest on the  Securities  to
         maturity  or  redemption  (in the  opinion of a  nationally  recognized
         accounting firm of independent  certified public accountants  expressed
         in a written certificate delivered to the Trustee) and to pay all other
         sums  payable by it  hereunder;  provided  that (i) the  trustee of the
         irrevocable  trust shall have been  irrevocably  instructed to pay such
         money  or the  proceeds  of such  U.S.  Government  Obligations  to the
         Trustee and (ii) the Trustee shall have been irrevocably  instructed to
         apply such money or the proceeds of such U.S. Government Obligations to
         the payment of said  principal,  premium,  if any,  and  interest  with
         respect to the Securities;

               (2)  the  Company  has  delivered  to the  Trustee  an  Officer's
         Certificate  stating  that (a) all  conditions  precedent  provided for
         relating to either the legal  defeasance  under  paragraph (b) above or
         the covenant  defeasance under paragraph (c) above, as the case may be,
         have  been  complied  with  and (b) if any  other  Indebtedness  of the
         Company shall then be outstanding or committed,  such legal  defeasance
         or  covenant   defeasance  will  not  violate  the  provisions  of  the
         agreements or instruments evidencing such Indebtedness;

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

               (4) the Trustee shall not have received notice from any holder of
          Bank  Debt  or any  holder  of  Senior  Indebtedness  in an  aggregate
          principal  amount in excess of $20 million that such legal  defeasance
          or covenant  defeasance would violate the provisions of the agreements
          or instruments evidencing such Senior Indebtedness;

               (5) such legal defeasance or covenant defeasance shall not result
          in a breach or  violation  of,  or  constitute  a default  or event of
          default  under,  this  Indenture  or any other  material  agreement or
          instrument to which the Company is a party or by which it is bound;

               (6) in the case of an election  under  paragraph  (b) above,  the
          Company shall have delivered to the Trustee an Opinion of Counsel from
          nationally  recognized  counsel acceptable to the Trustee stating that
          (x) the Company has received from, or there has been published by, the
          Internal  Revenue  Service a  ruling,  (y)  there  exists  controlling
          precedent,  or (z) since the date of this Indenture,  there has been a
          change in the  applicable  Federal  income tax law, in any case to the
          effect  that  the  Holders  of the  outstanding  Securities  will  not
          recognize  income,  gain or loss for Federal  income tax purposes as a
          result of such legal  defeasance and will be subject to federal income
          tax on the same  amount and in the same manner and at the same time as
          would have been the case if such legal  defeasance  had not  occurred;
          and

               (7) in the case of an election  under  paragraph  (c) above,  the
          Company shall have delivered to the Trustee an Opinion of Counsel from
          nationally  recognized  counsel  acceptable  to the Trustee (i) to the
          effect  that  the  Holders  of the  outstanding  Securities  will  not
          recognize  income,  gain or loss for Federal  income tax purposes as a
          result of such  covenant  defeasance  and will be  subject  to Federal
          income tax on the same  amount and in the same  manner and at the same
          time as would have been the case if such covenant  defeasance  had not
          occurred or (ii) that the Company has received from, or there has been
          published by, the Internal  Revenue  Service a ruling to the foregoing
          effect.

     After such  irrevocable  deposit  made  pursuant  to this  Section  8.1 and
satisfaction of the other conditions set forth herein,  the Trustee upon request
shall  acknowledge in writing the discharge of the Company's  obligations  under
this Indenture except for those surviving obligations specified above.

                                      -39-


     The Company may make an  irrevocable  deposit  pursuant to this Section 8.1
only if at such time it is not prohibited  from doing so under the provisions of
Article 10 and the Company  shall have  delivered  to the Trustee and any Paying
Agent an Officers' Certificate to that effect.

     In order to have money available on a payment date to pay the principal of,
premium, if any, or interest on the Securities,  the U.S. Government Obligations
shall be payable as to principal, premium, if any, or interest on or before such
payment date in such amounts as will provide the  necessary  money to effect the
applicable defeasance.  U.S. Government Obligations shall not be callable at the
issuer's option.

Section 8.2 Application of Trust Money

     The Trustee or a trustee  satisfactory to the Trustee and the Company shall
hold in trust money or U.S. Government Obligations deposited with it pursuant to
Section  8.1.  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,  premium,  if any, and interest on the
Securities.

Section 8.3 Repayment to the Company

     The Trustee and the Paying  Agent shall  promptly  pay to the Company  upon
written request any excess money or securities held by them at any time.

     The Trustee and the Paying  Agent shall pay to the Company at their  option
or upon  written  request any money held by them for the  payment of  principal,
premium, if any, or interest that remains unclaimed for two years after the date
upon which such  payment  shall have become  due;  provided,  however,  that the
Company  shall have either  caused  notice of such  payment to be mailed to each
Holder  entitled  thereto no less than 30 days prior to such repayment or within
such  period  shall have  published  such  notice in a  financial  newspaper  of
widespread  circulation  published in The City of New York. After payment to the
Company,  Holders  entitled to the money must look to the Company for payment as
general creditors unless an applicable abandoned property law designates another
Person,  and all  liability of the Trustee and such Paying Agent with respect to
such money shall cease.

Section 8.4 Reinstatement

     If the  Trustee  or  Paying  Agent is  unable  to apply  any  money or U.S.
Government  Obligations  in  accordance  with Section 8.1 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 Section 8.1 until
such time as the Trustee or Paying Agent is permitted to apply all such money or
U.S. Government  Obligations in accordance with Section 8.1; provided,  however,
that if the Company  has made any payment of premium,  if any, or 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 Paying Agent.


                                   ARTICLE 9.

                                   AMENDMENTS

Section 9.1 Without Consent of Holders

     The Company and the Trustee may amend this  Indenture or the  Securities or
waive any provision hereof without the consent of any Holder:

     (1) to comply with Section 5.1;

     (2) to evidence and provide for the acceptance of appointment  hereunder by
     a successor Trustee with respect to the Securities;


                                      -40-


     (3) to comply with a provision or provisions of the TIA  applicable to this
     Indenture;

     (4) to add to the  covenants  of the Company for the benefit of the Holders
     or an  additional  Event of Default or to provide for the  surrender by the
     Company of any right or power conferred upon it hereunder;

     (5) to secure the Securities or provide for any Guarantee by a Subsidiary;

     (6) to provide for the  issuance of  securities  identical  in all material
respects to the Rule 144A Notes pursuant to the Exchange Offer; or

     (7) to cure any ambiguity, correct or supplement any provision which may be
defective or inconsistent with any other provision  contained in this Indenture,
or make any provisions  with respect to matters or questions  arising under this
Indenture which shall not be inconsistent with the provisions of this Indenture,
provided  that such  modification  or amendment  does not  adversely  affect the
interests of the Holders.

     Upon the request of the Company,  accompanied  by a resolution of the Board
of Directors authorizing the execution of any such supplemental  indenture,  and
upon  receipt by the Trustee of the  documents  described  in Section  9.6,  the
Trustee  shall  join  with the  Company  in the  execution  of any  supplemental
indenture  authorized  or permitted by the terms of this  Indenture and make any
further  appropriate  agreements and stipulations that may be therein contained,
but the Trustee shall not be obligated to enter into any supplemental  indenture
that  affects its own  rights,  duties or  immunities  under this  Indenture  or
otherwise.  After an amendment or waiver under this Section  becomes  effective,
the Company shall mail to the Holders of each Security affected thereby a notice
briefly  describing the amendment or waiver.  Any failure of the Company to mail
such notice,  or any defect therein,  shall not,  however,  in any way impair or
affect the validity of any such supplemental indenture.

Section 9.2 With Consent of Holders

     Except as provided  in this  Section  9.2,  the Company and the Trustee may
amend this Indenture or the Securities  with the written  consent of the Holders
of at least a majority in principal amount of the then outstanding Securities.

     Upon the request of the Company,  accompanied  by a resolution of the Board
of Directors authorizing the execution of any such supplemental  indenture,  and
upon the filing  with the  Trustee of  evidence of the consent of the Holders as
aforesaid, and upon receipt by the Trustee of the documents described in Section
9.6,  the  Trustee  shall  join  with  the  Company  in the  execution  of  such
supplemental  indenture unless such supplemental indenture affects the Trustee's
own rights,  duties or immunities  under this  Indenture or otherwise,  in which
case the Trustee may in its  discretion,  but shall not be  obligated  to, enter
into such supplemental indenture.

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

     The  Holders of a  majority  in  principal  amount of the  Securities  then
outstanding  may waive  compliance in a particular  instance by the Company with
any  provision of this  Indenture or the  Securities.  However,  (a) without the
consent of each Holder  affected,  an amendment or waiver under this Section may
not:

     (1) change the Stated  Maturity of the principal of, or any  installment of
interest on, any Security;

     (2) reduce the principal amount of, or premium, if any, or interest on, any
Security;

     (3) change the place of payment  where,  or the coin or  currency in which,
any Security or any premium or interest thereon is payable;

     (4) impair the right of Holders to institute  suit for the  enforcement  of
payment of the  principal of and premium,  if any, and interest on Securities on
or after the Stated Maturity thereof (or in


                                      -41-


the case of redemption, on or after the redemption date);

     (5) reduce the percentage in principal amount of Securities, the consent of
whose Holders is required for any modification or amendment of the Indenture, or
the  consent of whose  Holders is  required  for any waiver of  compliance  with
certain  provisions of this  Indenture or certain  Defaults or Events of Default
hereunder and their consequences provided for in this Indenture; or

     (6)  modify  any of the  provisions  of  Section  6.4 or clause (a) of this
sentence of this Section 9.2, 
and (b) without  the  consent of the  Holders of at least 66_% of the  aggregate
principal amount of the outstanding Securities, an amendment or waiver may not:

     (1) amend, change or modify the provisions of Article Three relating to the
optional  redemption of Securities by the Company in accordance with Section 3.7
hereof;

     (2) amend,  change or modify the obligations of the Company with respect to
a Change in Control Repurchase  pursuant to Section 4.10 hereof or modify any of
the provisions or definitions relating thereto; or

     (3) modify or change  any  provision  of Article 10 in a manner  adverse to
Holders of the Securities; or

     (4) modify any of the  provisions  of clause (b) of this  sentence  of this
Section 9.2.

     The right of any Holder to  participate  in any consent  required or sought
pursuant to any provision of this  Indenture  (and the obligation of the Company
to obtain any such consent  otherwise  required from such Holder) may be subject
to the requirement  that such Holder shall have been the Holder of record of any
Securities with respect to which such consent is required or sought as of a date
identified by the Trustee in a notice  furnished to Holders in  accordance  with
the terms of this Indenture.

Section 9.3 Compliance with Trust Indenture Act

     Every  amendment to this Indenture or the  Securities  shall comply in form
and substance with the TIA as then in effect.

Section 9.4 Revocation and Effect of Consents

     Until an  amendment  (which  includes  any  supplement)  or waiver  becomes
effective,  a consent to it by a Holder of a Security is a continuing consent by
the Holder and every  subsequent  Holder of a Security  or portion of a Security
that  evidences  the same  debt as the  consenting  Holder's  Security,  even if
notation of the consent is not made on any  Security.  However,  any such Holder
may revoke the consent as to his or her Security or portion of a Security if the
Trustee receives  written notice of revocation  before the date the amendment or
waiver becomes effective. An amendment or waiver becomes effective in accordance
with  its  terms  and  thereafter  binds  every  Holder  of a  Security  whether
theretofore or thereafter authenticated and delivered.

     The Company may,  but shall not be obligated  to, fix a record date for the
purpose of  determining  the  Holders  entitled to consent to any  amendment  or
waiver. If the Company elects to fix a record date for such purpose,  the record
date shall be fixed at (i) the later of 30 days prior to the first  solicitation
of such consent or the date of the most recent list of Holders  furnished to the
Trustee prior to such solicitation, or (ii) such other date as the Company shall
designate. If a record date is fixed, then notwithstanding the provisions of the
immediately  preceding paragraph,  those Persons who were Holders at such record
date (or their  duly  designated  proxies),  and only  those  Persons,  shall be
entitled  to  consent  to such  amendment  or waiver or to  revoke  any  consent
previously given,  whether or not such Persons continue to be Holders after such
record date.  No consent shall be valid or effective for more than 90 days after
such  record  date  unless  consents  from  Holders of the  principal  amount of
Securities required hereunder for such amendment or waiver to be effective shall
have also been given and not revoked within such 90-day period.


                                      -42-



Section 9.5 Notation on or Exchange of Securities

     The Trustee may place an appropriate  notation about an amendment or waiver
on any  Security  thereafter  authenticated.  The  Company in  exchange  for the
Securities  may issue and the Trustee shall  authenticate  new  Securities  that
reflect the amendment or waiver.

Section 9.6 Trustee to Sign Amendments, etc.

     The Trustee shall sign any amendment or supplemental  indenture  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  or  refusing  to sign such
amendment or  supplemental  indenture,  the Trustee shall be entitled to receive
and, subject to Section 7.1 and 7.2 shall be fully protected in relying upon, an
Officers' Certificate and an Opinion of Counsel as conclusive evidence that such
amendment  or  supplemental   indenture  is  authorized  or  permitted  by  this
Indenture,  that it is not inconsistent  herewith, and that it will be valid and
binding upon the Company in accordance with its terms.


                                   ARTICLE 10.

                                  SUBORDINATION

Section 10.1 Securities Subordinated to Senior Indebtedness

     The Company  covenants  and agrees,  and each Holder of a Security,  by his
acceptance  thereof,  likewise covenants and agrees,  that, to the extent and in
the  manner   hereinafter  set  forth  in  this  Article  10,  the  indebtedness
represented by the Securities  and all Payments or  Distributions  in Respect of
the Securities are hereby  expressly  made  subordinate  and subject in right of
payment  to the  prior  payment  in full  of all  Senior  Indebtedness,  whether
outstanding on the date of this Indenture or thereafter incurred.

     If at any time  following  the  payment of any amount to a holder of Senior
Indebtedness with respect to such Senior Indebtedness, such payment is rescinded
or must  otherwise be returned by such holder upon the  insolvency,  bankruptcy,
reorganization, dissolution or liquidation of the Company or any other Person or
otherwise,  and is so rescinded or returned to the party or parties  making such
payment,  such Senior  Indebtedness  shall be  reinstated  to the extent of such
payment and the  provisions  of this Article 10 shall be  applicable  as if such
payment were never made.

     The  provisions  of this  Article 10 are for the  benefit of the holders of
Senior Indebtedness, and each Holder of the Securities, by his purchase or other
acquisition of the  Securities,  hereby agrees for the benefit of each holder of
Senior  Indebtedness  that his  Securities are subject to the provisions of this
Article 10.

Section 10.2 Payment Over of Proceeds Upon Dissolution, Etc.

     In the event of (a) any insolvency or bankruptcy case or proceeding, or any
receivership,  liquidation,  reorganization or other similar case or proceeding,
relative to the Company or to its creditors,  as such, or to a substantial  part
of its assets,  or (b) any proceeding for the liquidation,  dissolution or other
winding up of the Company,  whether  voluntary or involuntary and whether or not
involving  insolvency or  bankruptcy,  or (c) any  assignment for the benefit of
creditors or any other  marshalling  of assets and  liabilities  of the Company,
then and in any such event the holders of Senior  Indebtedness shall be entitled
to receive  payment in full of all amounts due or to become due on or in respect
of all Senior  Indebtedness  (including,  without  limitation,  all  Allowed and
Disallowed  Post-Commencement Interest and Expenses), or provision shall be made
for such payment in cash or in a manner otherwise satisfactory to the holders of
Senior  Indebtedness,  before the  Holders of the  Securities  are  entitled  to
receive any Payment or  Distribution  in Respect of the  Securities  (other than
payments of amounts deposited prior to any such case, proceeding, dissolution or
other  winding  up or event in  accordance  with the  defeasance  provisions  of
Article 8 hereof),  and to that end the holders of Senior  Indebtedness shall be
entitled to receive,  for  application  to the payment  thereof,  any payment or
distribution of any kind or character,  whether in cash, property or securities,
including any such payment or  distribution  which may be payable or deliverable
by  reason  of the  payment  of any  other  indebtedness  of the  Company  being
subordinated  to the  payment  of  the  Securities,  which  may  be  payable  or
deliverable  in  respect  of  the  Securities  in  any  such  case,  proceeding,
dissolution, liquidation or other winding up or event.


                                      -43-



     In the  event  that,  notwithstanding  the  foregoing  provisions  of  this
Section,  the  Trustee or the Holder of any  Security  shall have  received  any
Payment  or  Distribution  in  Respect  of  the  Securities  in any  such  case,
proceeding,  dissolution,  liquidation  or other winding up or event (other than
payments of amounts deposited prior to any such case, proceeding, dissolution or
other  winding  up or event in  accordance  with the  defeasance  provisions  of
Article 8  hereof),  including  any such  payment or  distribution  which may be
payable or deliverable by reason of the payment of any other indebtedness of the
Company being  subordinated to the payment of the Securities,  before all Senior
Indebtedness  (including,   without  limitation,   all  Allowed  and  Disallowed
Post-Commencement  Interest  and  Expenses)  is paid in full or payment  thereof
provided for, and, if (i) subject to Section 10.8,  such fact shall, at or prior
to the  time of such  payment  or  distribution,  have  been  made  known to the
Trustee,  then and in such event such payment or distribution shall be paid over
or  delivered   forthwith  to  the  holders  of  Senior  Indebtedness  or  to  a
representative   duly  appointed  by  any  such  holder  or  holders  of  Senior
Indebtedness  unless otherwise  required by law or court order or (ii) such fact
shall  have been made  known to such  Holder  at any time  before or after  such
payment, then and in such event such Holder shall forthwith pay over and deliver
such payment to the holders of Senior  Indebtedness or to a representative  duly
appointed  by any such  holder or holders  of such  Senior  Indebtedness  unless
otherwise required by law or court order, in either such case for application to
the payment of all Senior Indebtedness remaining unpaid, to the extent necessary
to pay all Senior Indebtedness (including,  without limitation,  all Allowed and
Disallowed Post-Commencement Interest and Expenses) in full, after giving effect

another Person or the  liquidation  or dissolution of the Company  following the
conveyance or transfer of its properties and assets substantially as an entirety
to another Person upon the terms and conditions set forth in Article 5 shall not
be deemed a dissolution, winding up, liquidation, reorganization, assignment for
the benefit of creditors or marshalling of assets and liabilities of the Company
for the purposes of this Section if the Person formed by such  consolidation  or
into which the  Company is merged or which  acquires by  conveyance  or transfer
such  properties and assets  substantially  as an entirety,  as the case may be,
shall, as a part of such consolidation,  merger,  conveyance or transfer, comply
with the conditions set forth in Article 5.

Section  10.3  Prior  Payment  to  Senior   Indebtedness  Upon  Acceleration  of
Securities

     In the event that any  Securities are declared due and payable before their
Stated  Maturity,  then and in such  event the  holders  of Senior  Indebtedness
outstanding  at the time such  Securities  so become  due and  payable  shall be
entitled  to  receive  payment  in  full  in  cash,  or  in a  manner  otherwise
satisfactory to the holders of Senior Indebtedness,  of all amounts due on or in
respect of such Senior Indebtedness (including,  without limitation, all Allowed
and Disallowed  Post-Commencement  Interest and Expenses)  before the Holders of
the Securities are entitled to receive any Payment or Distribution in Respect of
the  Securities  (including  any  payment  which may be payable by reason of the
payment of any other  indebtedness  of the  Company  being  subordinated  to the
payment of the Securities),  other than payment of amounts previously  deposited
in accordance with the defeasance  provisions of Article 8 hereof, by or for the
account of the Company.

     In the event that,  notwithstanding  the foregoing,  the Company shall make
any Payment or  Distribution  in Respect of the Securities to the Trustee or the
Holder of any Security  prohibited by the foregoing  provisions of this Section,
then if (i) subject to Section 10.8, such fact shall,  prior to the time of such
payment, have been made known to the Trustee, then and in such event the Trustee
shall  forthwith pay over and deliver such payment to the holders of such Senior
Indebtedness or to a representative duly appointed by any such holder or holders
of such Senior Indebtedness or (ii) such fact shall have been made known to such
Holder at any time  before or after  such  payment,  then and in such event such
Holder  shall  forthwith  pay over and  deliver  such  payment to the holders of
Senior  Indebtedness or to a representative duly appointed by any such holder or
holders of such Senior Indebtedness,  in either such case for application to the
payment of all Senior  Indebtedness  then remaining unpaid  (including,  without
limitation, all Allowed and Disallowed Post-Commencement Interest and Expenses),
after giving  effect to any  concurrent  payment or  distribution  to or for the
benefit of holders of Senior Indebtedness.

     The  provisions of this Section shall not apply to any payment with respect
to which Section 10.2 is applicable.

Section  10.4  No  Payment  Upon  Certain   Defaults   with  Respect  to  Senior
Indebtedness


                                      -44-


     (a) No Payment or  Distribution  in Respect of the  Securities  (other than
payments of amounts  previously  deposited  in  accordance  with the  defeasance
provisions  of  Article 8  hereof)  shall be made by or for the  account  of the
Company or any other Person upon its behalf upon the  occurrence  of any default
in the payment of principal,  premium,  if any,  interest on or any other amount
due under or with  respect  to any Bank Debt or any Senior  Indebtedness  (other
than Bank Debt) in excess of $20 million  beyond any  applicable  grace  period,
unless  and  until  such  default  is cured or waived or ceases to exist or such
Senior  Indebtedness has been paid in full or provision for such payment in cash
or in a manner otherwise satisfactory to holders of Senior Indebtedness has been
made.

     (b) Upon any default  with  respect to the  financial  covenants  under the
Credit Agreement as specified therein,  or if any payment or distribution by the
Company with  respect to any Security  would,  immediately  after giving  effect
thereto,  result in such default,  no Payment or  Distribution in Respect of the
Securities  (other than payments of amounts  previously  deposited in accordance
with the defeasance provisions of Article 8 hereof), including any payment which
may be  payable  by  reason  of the  payment  of any  other  indebtedness  being
subordinated  to the  payment  of the  Securities,  shall  be made by or for the
account of the  Company  on  account of  principal  of or  premium,  if any,  or
interest on the  Securities or on account of the  purchase,  redemption or other
acquisition  of the  Securities  for the period  specified  below (the  "Payment
Blockage  Period").  The Payment Blockage Period shall commence upon the receipt
of notice by the Company or the Trustee from the Bank Agent and shall end on the
earlier of (i) 179 days  thereafter,  (ii) the date on which such  default  with
respect to the financial covenants under the Credit Agreement is cured or waived
or ceases to exist or on which such Bank Debt is paid in full or  provision  for
such  payment in money or money's  worth has been made,  (iii) the date on which
the maturity of any  Indebtedness  (other than Senior  Indebtedness)  shall have
been accelerated by virtue of such event, or (iv) the date on which such Payment
Blockage  Period shall have been  terminated by written notice to the Company or
the Trustee from the Bank Agent,  after which any and all  required  payments in
respect of the Securities,  including any missed payments,  may resume. Only one
Payment  Blockage  Period may be commenced  during any period of 365 consecutive
days.  No default  with  respect  to the  financial  covenants  under the Credit
Agreement that existed or was continuing on the date of the  commencement of any
Payment  Blockage Period will be, or can be, made the basis for the commencement
of a second  Payment  Blockage  Period  whether  or not  within a period  of 365
consecutive  days,  unless such default has been cured or waived for a period of
not less than 90 consecutive  days. In no event will a Payment  Blockage  Period
extend beyond 179 days from the receipt by the Trustee of notice initiating such
Payment  Blockage  Period and there must be a 186  consecutive day period in any
365 day period during which no Payment Blockage Period is in effect.

     (c) In the event that,  notwithstanding  the  foregoing,  the Company shall
make any payment to the Trustee or the Holder of any Security  prohibited by the
foregoing provisions of this Section,  then (i) subject to Section 10.8, if such
fact shall, at or prior to the time of such payment, have been made known to the
Trustee, then and in such event the Trustee shall forthwith pay over and deliver
such payment to the holders of Senior  Indebtedness or to a representative  duly
appointed by any such holder or holders of such Senior Indebtedness or (ii) such
fact shall have been made known to such  Holder at any time before or after such
payment, then and in such event such Holder shall forthwith pay over and deliver
such payment to the holders of Senior  Indebtedness or to a representative  duly
appointed by any such holder or holders of such Senior Indebtedness.


                                      -45-


     The  provisions of this Section shall not apply to any payment with respect
to which Section 10.2 is applicable.

Section 10.5 Payment Permitted If No Default

     Nothing  contained in this Article or elsewhere in this Indenture or in any
of the Securities  shall prevent (a) the Company,  at any time except during the
pendency of any case, proceeding, dissolution,  liquidation or other winding up,
assignment  for the  benefit of  creditors  or other  marshalling  of assets and
liabilities  of the Company  referred to in Section 10.2 or under the conditions
described  in  Section  10.3  or  Section  10.4,  from  making  any  Payment  or
Distribution in Respect of the Securities, or (b) the application by the Trustee
of any  money  deposited  with it  hereunder  with  respect  to any  Payment  or
Distribution  in Respect of the  Securities  or the retention of such Payment or
Distribution  in Respect of the  Securities  by the Holders,  if, at the time of
such  application  by the Trustee,  it had not been notified in accordance  with
Section 10.8 that such payment was  prohibited by the provisions of this Article
10.

Section 10.6 Subrogation to Rights of Holders of Senior Indebtedness

     Subject to the  payment in full in cash of all amounts due on or in respect
of  Senior  Indebtedness  (including,   without  limitation,   all  Allowed  and
Disallowed  Post-Commencement  Interest  and  Expenses,  except  to  the  extent
provided below), the Holders of the Securities shall be subrogated to the extent
of the payments or distributions made to the holders of such Senior Indebtedness
pursuant to the  provisions  of this  Article 10 (equally  and ratably  with the
holders  of all  indebtedness  of the  Company  which  by its  express  terms is
subordinated  to other  indebtedness  of the Company to  substantially  the same
extent as the  Securities  are  subordinated  and are entitled to like rights of
subrogation) to the rights of the holders of such Senior Indebtedness to receive
payments and  distributions of cash,  property and securities  applicable to the
Senior  Indebtedness until the principal of and premium, if any, and interest on
the  Securities  shall be paid in full.  For  purposes of such  subrogation,  no
payments or distributions to the holders of the Senior Indebtedness of any cash,
property or  securities  to which the Holders of the  Securities  or the Trustee
would be entitled  except for the provisions of this Article 10, and no payments
over  pursuant  to the  provisions  of this  Article  to the  holders  of Senior
Indebtedness  by Holders of the Securities or the Trustee,  shall,  as among the
Company, its creditors other than holders of Senior Indebtedness and the Holders
of the  Securities,  be deemed to be a payment or distribution by the Company to
or on account of the Senior Indebtedness.

     Notwithstanding  anything to the contrary in this Section 10.6, the Holders
of the  Securities  hereby  agree that they shall have no rights of  subrogation
with respect to amounts paid to the holders of Senior Indebtedness in payment of

Section 10.7 Provisions Solely to Define Relative Rights











                                      -46-


     The  provisions  of this  Article  10 are and are  intended  solely for the
purpose of defining the relative  rights of the Holders of the Securities on the
one hand and the  holders  of Senior  Indebtedness  on the other  hand.  Nothing
contained in this Article or elsewhere in this Indenture or in the Securities is
intended to or shall (a) impair, as among the Company,  its creditors other than
holders of Senior Indebtedness and the Holders of the Securities, the obligation
of the Company,  which is absolute and  unconditional,  to pay to the Holders of
the  Securities  the  principal  of and  premium,  if any,  and  interest on the
Securities as and when the same shall become due and payable in accordance  with
their  terms;  or (b) affect the  relative  rights  against  the  Company of the
Holders of the Securities and creditors of the Company other than the holders of
Senior  Indebtedness;  or (c) prevent the Trustee or the Holder of any  Security
from exercising all remedies otherwise  permitted by applicable law upon default
under this  Indenture,  subject to the rights,  if any, under this Article 10 of
the holders of Senior  Indebtedness  to receive  cash,  property and  securities
otherwise  payable or deliverable to the Trustee or such Holder.  The failure to
make a payment on account of principal of,  premium,  if any, or interest on, or
any other amounts then payable with respect to, the  Securities by any reason of
this Article 10 shall not be construed as preventing  the occurrence of an Event
of Default under Section 6.1.

Section 10.8 Application by Trustee of Monies Deposited With It

     Money and U.S. Government  Obligations  deposited in trust with the Trustee
pursuant to Section 8.2 and in compliance with Section 8.1 shall be for the sole
benefit  of the  Holders  and,  to the  extent  allocated  for  the  payment  of
Securities, shall not be subject to the subordination provisions of this Article
10.  Otherwise,  any  deposit of monies by the  Company  with the Trustee or any
Paying Agent  (whether or not in trust) for payment on account of principal  of,
premium, if any, and interest on the Securities or that otherwise  constitutes a
Payment or  Distribution  in Respect of the  Securities  shall be subject to the
provisions of Sections 10.1,  10.2, 10.3 and 10.4 except that, if at least three
Business Days prior to the date on which by the terms of this Indenture any such
monies may become payable for any purpose (including,  without  limitation,  the
payment of the principal of,  premium,  if any, or the interest on any Security)
the  Trustee  shall not have  received  with  respect to such  monies the notice
provided for in Section 10.4(b) or 10.11, then the Trustee shall have full power
and  authority  to receive  such monies and to apply the same to the purpose for
which  they  were  received,  and  shall not be  affected  by any  notice to the
contrary  which may be received by it within three  Business  Days of such date.
This Section shall be construed solely for the benefit of the Trustee and Paying
Agent  and  shall  not  otherwise   affect  the  rights  of  holders  of  Senior
Indebtedness.

Section 10.9 Trustee to Effectuate Subordination

     Each holder of a Security by his acceptance  thereof authorizes and directs
the Trustee on his behalf to take such action as may be necessary or appropriate
to  effectuate  the  subordination  provided in this  Article and  appoints  the
Trustee his attorney-in-fact for any and all such purposes.

Section 10.10 No Waiver of Subordination Provisions

     No right of any  present  or future  holder of any Senior  Indebtedness  to
enforce  subordination  as  herein  provided  shall  at any  time  in any way be
prejudiced  or  impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith,  by any such  holder,  or by any
noncompliance  by the Company with the terms,  provisions  and covenants of this
Indenture,  regardless of any  knowledge  thereof any such holder may have or be
otherwise charged with.

     Without in any way limiting the generality of the foregoing paragraph,  the
holders of Senior  Indebtedness may, at any time and from time to time,  without
the  consent  of or notice to the  Trustee  or the  Holders  of the  Securities,
without  incurring  responsibility  to the Holders of the Securities and without
impairing  or  releasing  the  subordination  provided  in this  Article  or the
obligations  hereunder of the Holders of the Securities to the holders of Senior
Indebtedness,  do any one or more of the following: (i) change the manner, place
or terms of  payment  or  extend  the time of  payment  of,  or renew or  alter,
compromise,  accelerate,  extend or refinance Senior Indebtedness,  or otherwise
amend  or  supplement  in any  manner  Senior  Indebtedness  or  any  instrument
evidencing  the  same  or any  agreement  under  which  Senior  Indebtedness  is
outstanding; (ii) sell, exchange, release, foreclose upon or otherwise deal with
any property pledged, mortgaged or otherwise securing Senior Indebtedness; (iii)
release any Person  liable in any manner for the payment or collection of Senior
Indebtedness;  (iv) exercise or refrain from  exercising  any rights against the
Company  and any other  Person;  (v)  increase or reduce the rate of interest or
amount  of  principal  payable  on any  Senior  Indebtedness;  (vi)  release  or
discharge  the  Company,  by  acceptance  of a deed  or  assignment  in  lieu of
foreclosure or otherwise,  as to all or any portion of the Senior  Indebtedness;
or (vii)  release,  substitute  or add any one or more


                                      -47-


guarantors or endorsers,  accept additional or substituted  security for payment
or  performance  of the  Senior  Indebtedness,  or release  or  subordinate  any
security therefor. No exercise,  delay in exercise or failure to exercise by any
holder of any Senior  Indebtedness  of any right  hereby given it, no dealing by
any holder of any Senior  Indebtedness  with the Company or any other guarantor,
endorser or other  person,  no change,  impairment or suspension of any right or
remedy of any holder of any Senior  Indebtedness,  and no act or thing which but
for this  provision  could act as a release or exoneration of the Holders of the
Securities hereunder, shall in any way affect, decrease,  diminish or impair any
of the  obligations  of the Holders of the Securities and the Trustee or give to
the Holders of the  Securities,  the  Trustee or any other  person or entity any
recourse or defense against any holder of any Senior Indebtedness.

Section 10.11 Notice to Trustee

     The  Company  shall give prompt  written  notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the  Securities.  Notwithstanding  the  provisions of this
Article or any other  provision  of this  Indenture,  the  Trustee  shall not be
charged with  knowledge of the  existence of any facts which would  prohibit the
making of any payment to or by the Trustee in respect of the Securities,  unless
and until the  Trustee  shall have  received  written  notice  thereof  from the
Company  or a  holder  of  Senior  Indebtedness  or from  any  trustee  or other
representative  therefor;  and, prior to the receipt of any such written notice,
the  Trustee,  subject  to the  provisions  of  Sections  7.1 and 7.2,  shall be
entitled in all respects to assume that no such facts exist.

     Subject to the  provisions  of Sections 7.1 and 7.2,  the Trustee  shall be
entitled  to  rely  on  the  delivery  to it of a  written  notice  by a  Person
representing  himself  to be a  holder  of  Senior  Indebtedness  (or a  trustee
therefor)  to  establish  that such  notice has been given by a holder of Senior
Indebtedness (or a trustee  therefor).  In the event that the Trustee determines
in good faith that further evidence is required with respect to the right of any
Person as a holder of Senior  Indebtedness  to  participate  in any  payment  or
distribution pursuant to this Article 10, the Trustee may request such Person to
furnish evidence to the reasonable  satisfaction of the Trustee as to the amount
of Senior  Indebtedness held by such Person,  the extent to which such Person is
entitled to  participate  in such  payment or  distribution  and any 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.

     Upon any payment or  distribution  of assets of the Company  referred to in
this Article 10, the Trustee, subject to the provisions of Sections 7.1 and 7.2,
and the  Holders of the  Securities  shall be entitled to rely upon any order or
decree entered by any court of competent  jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation,  reorganization,  dissolution, winding up
or similar case or  proceeding is pending,  or a  certificate  of the trustee in
bankruptcy,  receiver,  liquidating trustee, custodian, assignee for the benefit
of  creditors,  agent or other  person  making  such  payment  or  distribution,
delivered  to the  Trustee or to the Holders of  Securities,  for the purpose of
ascertaining   the  Persons   entitled  to   participate   in  such  payment  or
distribution,  the holders of the 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.

     The Trustee shall not be deemed to owe any fiduciary duty to the holders of
Senior  Indebtedness  and shall not be liable to any such holders if it shall in

Senior Indebtedness shall be entitled by virtue of this Article 10 or otherwise.

Section 10.14 Rights of Trustee as Holder of Senior  Indebtedness;  Preservation
of Trustee's Rights

                    9 1/2% SENIOR SUBORDINATED NOTES DUE 2007


     1. Interest.  INTEGRATED HEALTH SERVICES, INC., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Security at
9 1/2% per annum  from the date this  Security  is issued  until  maturity.  The
Company  will pay  interest  semiannually  on March 15 and  September 15 of each
year, or if any such day is not a Business Day, on the next succeeding  Business
Day (each an "Interest  Payment Date") and any Penalty Interest payable pursuant
to Section 6 of the Registration Rights Agreement on such Interest Payment Date.
Interest  on the  Securities  will  accrue  from the most  recent  date on which
interest  has been  paid or,  if no  interest  has been  paid,  from the date of
issuance;  provided,  that if there is no  existing  Default  in the  payment of
interest,  and if this Security is authenticated  between a record date referred
to on the face hereof and the next succeeding  Interest  Payment Date,  interest
shall accrue from such next succeeding Interest Payment Date; provided, further,
that the first Interest Payment Date shall be September 15, 1997.  Interest will
be computed on the basis of a 360-day year of twelve 30-day months.

     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  record  date next  preceding  the
Interest  Payment Date,  even if such  Securities are canceled after such record
date and on or before such  Interest  Payment Date. In the case of a Security to
be repurchased by the Company in connection with a Change in Control  Repurchase
pursuant to paragraph 6, on or after an interest  payment  record date and prior
to the next Interest Payment Date, the registered  holder of such Security as of
such  record  date shall be  entitled  to accrued  and  unpaid  interest  to the
repurchase  date,  as provided in paragraph 6 below.  The Holder must  surrender
this Security to a Paying Agent to collect principal payments.  The Company will
pay the principal of,  premium,  if any, and interest on the Securities in money
of the United  States of America that at the time of payment is legal tender for
payment of public and private debts. Such amounts will be payable (i) in respect
of Securities in book-entry form held of record by the Depository  Trust Company
("DTC") or its nominee,  in same day funds on or prior to the payment dates with
respect to such amounts and (ii) in respect of Securities issued in certificated
form,  at the office of the Trustee,  and the  Securities  may be presented  for
registration  of  transfer  or  exchange,  at the  offices of the  Trustee.  The
Company,  however,  may pay such amounts in respect of the Securities  issued in
certificated form by check payable in such money mailed to a Holder's registered
address.

     3. Paying Agent and  Registrar.  Initially,  FIRST UNION  NATIONAL  BANK OF
VIRGINIA,  the  Trustee  under  the  Indenture,  will act as  Paying  Agent  and
Registrar.  The Company may change any Paying Agent,  Registrar or  co-registrar
without notice to any Holder.  The Company or any of its Subsidiaries may act in
any such capacity.

     4. Indenture. The Company issued the Securities under an Indenture dated as
of May 30, 1997 ("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, as amended (15 U.S.
Code  ss.ss.  77aaa-77bbbb),  as in  effect  on the  date  of  execution  of the
Indenture.  The  Securities  are  subject to all such  terms,  and  Holders  are
referred  to the  Indenture  and such Act for a  statement  of such  terms.  The
Securities  are  unsecured  general   obligations  of  the  Company  limited  to
$450,000,000 in aggregate  principal amount, plus amounts, if any, sufficient to
pay interest on outstanding  Securities as set forth in Paragraph 2 hereof.  The
Securities will rank pari passu with the Exchange  Notes,  the Company's 10 1/4%
Senior  Subordinated  Notes due 2006,  the Company's 9 5/8% Senior  Subordinated
Notes due 2002, Series A and the Company's 10 3/4% Senior Subordinated Notes due
2004.

     5. Optional Redemption. The Company may redeem all or any of the Securities
at any time on or after  September 15, 2002 at the following  redemption  prices
(expressed as percentages of principal amount), plus accrued and unpaid interest
to the redemption date:


                                       A-4


    If Redeemed During                 
the 12-Month Period Commencing                     Redemption Price
- ------------------------------                     ----------------
September 15, 2002                                     104.750%
September 15, 2003                                     103.167%
September 15, 2004                                     101.583%
September 15, 2005 and thereafter                        100%

     Notwithstanding  the foregoing,  the Company may redeem in the aggregate up
to $150,000,000 principal amount of Securities at any time and from time to time
prior to  September  15,  2000 at a  redemption  price  equal to 108.500% of the
aggregate principal amount so redeemed,  plus accrued interest to the redemption
date,  out of the net cash  proceeds  of one or more  Public  Equity  Offerings;
provided that at least  $300,000,000  aggregate  principal  amount of Securities
originally  issued  remains   outstanding  after  the  occurrence  of  any  such
redemption  and that any such  redemption  occurs  within 60 days  following the
closing of any such Public Equity Offering.

     6. Right to Require  Repurchase.  Following the occurrence of any Change in
Control,  each Holder will have the right to require that the Company repurchase
(a "Change in Control  Repurchase") such Holder's Securities at a purchase price
equal to 101% of the aggregate principal amount of the Securities,  plus accrued
and unpaid interest thereon,  if any, to the date of repurchase.  Within 30 days
after any Change in  Control,  the  Company or, at the  Company's  request,  the
Trustee, shall cause to be mailed a notice to all Holders notifying such Holders
of the  occurrence of such Change in Control,  the Holder's  rights arising as a
result thereof and the procedures to be followed by Holders  wishing to exercise
such rights.

     A Holder  of  Securities  may  exercise  the  right to  require a Change in
Control  Repurchase  after  receipt of notice of the  existence of such right by
completing the form entitled  "OPTION OF HOLDER TO ELECT PURCHASE"  appearing on
this  Security  and by  complying  with the other  procedures  set forth in such
notice.  Any portion of  Securities  with respect to which the Holder  wishes to
exercise such right must be in integral multiples of $1,000.

     7. Mandatory Offer to Repurchase.  If the Company consummates an Asset Sale
(as such term is defined in the  Indenture),  the  Company  may,  under  certain
circumstances,  be  required to utilize a portion of the net  proceeds  received
from such Asset Sale to offer to purchase  Securities at a purchase  price equal
to 100% of the  aggregate  principal  amount  of the  Securities,  plus  accrued
interest to the date fixed for redemption  (the "Asset Sale Offer").  Holders of
Securities  that are the subject of an offer to purchase  will  receive an Asset
Sale Offer from the Company or the  Trustee.  The Asset Sale Offer shall  remain
open for a period of 30 days  after its  commencement  unless a longer  offering
period is required by law (the  "Asset Sale Offer  Period").  On or prior to the
fifth Business Day following the termination of the Asset Sale Offer Period (the
"Asset Sale Payment Date"), the Company shall purchase,  or cause the Trustee to
purchase,  and mail or deliver payment for the amount of Securities  required to
be  purchased  pursuant  to the Asset  Sale Offer or, if less than the amount of
Securities  required to be  purchased  pursuant to the Asset Sale Offer has been
tendered, all Securities tendered in response to the Asset Sale Offer

     A Holder of  Securities  may tender or refrain  from  tendering  all or any
portion of his  Securities at his  discretion  by  completing  the form entitled
"OPTION OF HOLDER TO ELECT PURCHASE" appearing on this Security.  Any portion of
Securities tendered must be in integral multiples of $1,000.

     8. Notice of  Redemption.  Notice of Redemption  will be mailed at least 30
days but not more than 60 days  before  the  redemption  date to each  Holder of
Securities to be redeemed at his registered address. Securities in denominations
larger  than  $1,000  may be  redeemed  in part but only in whole  multiples  of
$1,000, unless all of the Securities held by a Holder are to be redeemed. On and
after the  redemption  date  interest  will  cease to accrue  on  Securities  or
portions  thereof  called for  redemption  (unless the  Company  defaults on its
obligation to repurchase Securities).

     9.  Subordination.  The indebtedness  evidenced by this Security is, to the
extent provided in the Indenture, subordinate and subject in right of payment to
the  prior  payment  in full  of all  Senior  Indebtedness  (as  defined  in the
Indenture),  and this  Security  is  issued  subject  to the  provisions  of the
Indenture with respect thereto.  Each Holder of this Security,  by accepting the
same,  (a) agrees to and shall be bound by such  provisions,  (b) authorizes and
directs


                                      A-5


the Trustee on his behalf to take such action as may be necessary or appropriate
to effectuate the  subordination  so provided,  and (c) appoints the Trustee his
attorney-in-fact for any and all such purposes.

     10.  Denominations,  Transfer,  Exchange.  The Securities are in registered
form  without  coupons in  denominations  of $1,000 and  integral  multiples  of
$1,000.  The transfer of Securities  may be  registered  and  Securities  may be
exchanged  as  provided  in the  Indenture.  The  Registrar  and the Trustee may
require a Holder,  among other things, to furnish  appropriate  endorsements and
transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture.

     11.  Persons  Deemed  Owners.  The  registered  Holder of a Security may be
treated as its owner for all purposes.

     12. Amendments and Waivers. Subject to certain exceptions, the Indenture or
the Securities may be amended or supplemented with the consent of the Holders of
at least a majority in principal amount of the Securities then outstanding,  and
any existing  default under,  or compliance with any provision of, the Indenture
may be waived  (other  than any  continuing  Default  or Event of Default in the
payment of interest or premium, if any, on or the principal of the Securities or
in respect of a  provision  under the  Indenture  which  cannot be  modified  or
amended  without the consent of the Holder of each  Security  then  outstanding)
with the  consent  of the  Holders  of a  majority  in  principal  amount of the
Securities then outstanding.  Without the consent of any Holder, the Company and
the Trustee may amend or supplement  the Indenture or the  Securities to provide
for the  assumption  of the  Company's  obligations  to Holders in the case of a
merger or acquisition; to evidence and provide for the acceptance of appointment
of any successor Trustee under the Indenture; to comply with the requirements of
the Trust  Indenture  Act of 1939,  as amended;  to add to the  covenants of the
Company for the benefit of the Holders or an  additional  Event of Default or to
provide for the surrender by the Company of any right or power conferred upon it
under the  Indenture;  secure the  Securities  or provide for any Guarantee by a
Subsidiary;  to provide for the issuance of securities identical in all material
respects  to the  Securities  pursuant  to the  Exchange  Offer;  or to cure any
ambiguity,  correct  or  supplement  any  provision  which may be  defective  or
inconsistent  with any other provision in the Indenture,  or make any provisions
with respect to matters or questions arising under the Indenture which shall not
be  inconsistent  with the  provisions  of the  Indenture,  provided  that  such
modification  or  amendment  does not  adversely  affect  the  interests  of the
holders.

     The right of any Holder to  participate  in any consent  required or sought
pursuant to any provision of the Indenture (and the obligation of the Company to
obtain any such consent  otherwise  required from such Holder) may be subject to
the  requirement  that such  Holder  shall have been the Holder of record of any
Securities with respect to which such consent is required or sought as of a date
identified by the Trustee in a notice  furnished to Holders in  accordance  with
the terms of the Indenture.

     Without  the consent of each Holder  affected,  the Company may not,  among
other  things,  (i) change  the  Stated  Maturity  of the  principal  of, or any
installment of interest on, any Security,  (ii) reduce the principal  amount of,
or premium,  if any, or interest  on, any  Security,  (iii)  change the place of
payment where, or the coin or currency in which,  any Security or any premium or
interest thereon is payable, (iv) impair the right of a Holder to institute suit
for the  enforcement  of payment of the  principal of and  premium,  if any, and
interest on any Security on or after the Stated Maturity thereof (or in the case
of a redemption,  on or after the redemption  date) or (v) reduce the percentage
in principal  amount of Securities  the consent of whose Holders is required for
any modification or amendment of the Indenture,  or the consent of whose Holders
is  required  for any  waiver  of  compliance  with  certain  provisions  of the
Indenture or certain Defaults or Events of Default thereunder.

     Without the consent of at least 66_% of the aggregate  principal  amount of
outstanding  Securities,  the  Company  may not (i) amend,  change or modify the
provisions of Article Three of the Indenture relating to the optional redemption
of the  Securities by the Company in accordance  with Section 3.7 thereof,  (ii)
amend,  change or modify the obligations of the Company with respect to a Change
in Control Repurchase pursuant to Section 4.10 of the Indenture or modify any of
the  provisions or  definitions  relating  thereto or (iii) modify or change any
provision  of the  Indenture  affecting  the  subordination  or  ranking  of the
Securities in a manner adverse to Holders of the Securities.

     13.  Defaults  and  Remedies.  Events of Default  include:  (i)  default in
payment of  principal or premium on the  Securities;  (ii) default in payment of
interest on the Securities for 30 days; (iii) failure by the Company for 45 days
after notice to it to comply with any of its other  agreements  in the Indenture
or the Securities;  (iv) any  acceleration of Indebtedness of the Company or its
Subsidiaries  having  an  outstanding  principal  amount of $10  million


                                      A-6



in the aggregate or a failure to pay such Indebtedness at its stated maturity if
such  acceleration  or  failure  to pay is not  cured  within  10  days  of such
acceleration  or  failure  to pay;  and (v)  certain  events  of  bankruptcy  or
insolvency. If an Event of Default occurs and is continuing,  the Trustee or the
Holders of at least 25% in aggregate  principal  amount of the then  outstanding
Securities may declare all the Securities to be immediately  due and payable for
an amount equal to 100% of the principal amount of the Securities,  and premium,
if any, plus accrued interest to the date of payment, except that in the case of
an Event of Default arising from certain events of bankruptcy or insolvency, all
outstanding Securities become due and payable immediately without further action
or notice.  Holders may not enforce the  Indenture or the  Securities  except as
provided in the Indenture.  The Trustee may require indemnity satisfactory to it
before  it  enforces  the  Indenture  or  the  Securities.  Subject  to  certain
limitations,  Holders of a majority in principal  amount of the then outstanding
Securities  may direct the Trustee in its  exercise  of any trust or power.  The
Trustee may withhold from Holders  notice of any  continuing  default  (except a
default in payment of principal or interest or that resulted from the failure of
the Company to comply with its  obligations  with respect to Holders'  rights to
require repurchase of Securities upon a Change in Control) if it determines that
withholding  notice is in their  interests.  The Company  must furnish an annual
compliance certificate to the Trustee.

     14. Trustee  Dealings with Company.  The Trustee,  in its individual or any
other capacity,  may make loans to, accept  deposits from, and perform  services
for the Company or its  Affiliates,  and may otherwise  deal with the Company or
its Affiliates, as if it were not Trustee.

     15.  No  Recourse  Against  Others.  A  director,   officer,   employee  or
stockholder,  as such,  of the  Company  shall  not 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 Holder by  accepting  a Security  waives and  releases  all such
liability. The waiver and release are part of the consideration for the issuance
of the Securities.

     16. ERISA Matters.  Each Holder of Securities,  by its acceptance  thereof,
will be deemed to certify  that (i) no part of the funds used by such  Holder to
purchase the Securities  constitutes  assets of an employee benefit plan or (ii)
the  acquisition  and continued  holding of the Securities  will be covered by a
U.S.   Department  of  Labor  class   exemption   (with  respect  to  prohibited
transactions set forth under Section 406(a) of ERISA).

     17. Authentication. This Security shall not be valid until authenticated by
the manual signature of the Trustee or an authenticating agent.

     18.  Abbreviations.  Customary  abbreviations  may be used in the name of a
Holder  or an  assignee,  such  as:  TEN  COM  (--tenants  in  common),  TEN ENT

survivorship  and not as tenants in  common),  CUST  (--Custodian),  and U/G/M/A
(--Uniform Gifts to Minors Act).


     The Company  will  furnish to any Holder upon  written  request and without
charge a copy of the Indenture. Request may be made to:

               9 1/2% SENIOR SUBORDINATED NOTES DUE 2007, SERIES A


     1. Interest.  INTEGRATED HEALTH SERVICES,  INC. a Delaware corporation (the
"Company"),  promises to pay  interest on the  principal  amount of his Security
(which has been  exchanged for one of the  Company's 9 1/2% Senior  Subordinated
Notes due 2007 (the  "Rule  144A  Notes)) at 9 1/2% per annum from the date this
security is issued until maturity. The Company will pay interest semiannually on
March 15 and  September  15 of each  year,  or if any such day is not a Business
Day, on the next  succeeding  Business  Day (each an "Interest  Payment  Date").
Interest  on the  Securities  will  accrue  from the most  recent  date on which
interest  has been paid or, if no interest  has been paid,  from the most recent
date on which  interest  was paid on the Rule 144A Notes or, if no interest  was
paid on the Rule 144A Notes, from the date of original issuance of the Rule 144A
Notes;  provided,  that if  there  is no  existing  Default  in the  payment  of
interest,  and if this Security is authenticated  between a record date referred
to on the face hereof and the next succeeding  Interest  Payment Date,  interest
shall accrue from such next succeeding Interest Payment Date; provided, further,
that the first Interest Payment Date shall be September 15, 1997.  Interest will
be computed on the basis of a 360-day year of twelve 30-day months.

     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  record  date next  preceding  the
Interest  Payment Date,  even if such  Securities are canceled after such record
date and on or before such  Interest  Payment Date. In the case of a Security to
be repurchased by the Company in connection with a Change in Control  Repurchase
pursuant to paragraph 6, on or after an interest  payment  record date and prior
to the next Interest Payment Date, the registered  holder of such Security as of
such  record  date shall be  entitled  to accrued  and  unpaid  interest  to the
repurchase  date,  as provided in paragraph 6 below.  The Holder must  surrender
this Security to a Paying Agent to collect principal payments.  The Company will
pay the principal of,  premium,  if any, and interest on the Securities in money
of the United  States of America that at the time of payment is legal tender for
payment of public and private debts. Such amounts will be payable (i) in respect
of Securities in book-entry form held of record by the Depository  Trust Company
("DTC") or its nominee,  in same day funds on or prior to the payment dates with
respect to such amounts and (ii) in respect of Securities issued in certificated
form,  at the office of the Trustee,  and the  Securities  may be presented  for
registration  of  transfer  or  exchange,  at the  offices of the  Trustee.  The
Company,  however,  may pay such amounts in respect of the Securities  issued in
certificated form by check payable in such money mailed to a Holder's registered
address.

     3. Paying Agent and  Registrar.  Initially,  FIRST UNION  NATIONAL  BANK OF
VIRGINIA,  the  Trustee  under  the  Indenture,  will act as  Paying  Agent  and
Registrar.  The Company may change any Paying Agent,  Registrar or  co-registrar
without notice to any Holder.  The Company or any of its Subsidiaries may act in
any such capacity.

     4. Indenture. The Company issued the Securities under an Indenture dated as
of May 30, 1997 ("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, as amended (15 U.S.
Code  ss.ss.  77aaa-77bbbb),  as in  effect  on the  date  of  execution  of the
Indenture.  The  Securities  are  subject to all such  terms,  and  Holders  are
referred  to the  Indenture  and such Act for a  statement  of such  terms.  The
Securities  are  unsecured  general   obligations  of  the  Company  limited  to
$450,000,000 in aggregate  principal amount, plus amounts, if any, sufficient to
pay interest on outstanding  Securities as set forth in Paragraph 2 hereof.  The
Securities will rank pari passu with the Rule 144A Notes,  the Company's 10 1/4%
Senior  Subordinated Notes due 2006, the Company's 9_% Senior Subordinated Notes
due 2002, Series A and the Company's 10 3/4% Senior Subordinated Notes due 2004.

     5. Optional Redemption. The Company may redeem all or any of the Securities
at any time on or after  September 15, 2002 at the following  redemption  prices
(expressed as percentages of principal amount), plus accrued and unpaid interest
to the redemption date:


                                      B-3



     If Redeemed During                                Redemption Price
 the 12-month Period Commencing                        ----------------
- -------------------------------                        
September 15, 2002                                          104.750%
September 15, 2003                                          103.167%
September 15, 2004                                          101.583%
September 15, 2005 and thereafter                             100%

     Notwithstanding  the foregoing,  the Company may redeem in the aggregate up
to $150,000,000 principal amount of Securities at any time and from time to time
prior to  September  15,  2000 at a  redemption  price  equal to 108.500% of the
aggregate principal amount so redeemed,  plus accrued interest to the redemption
date,  out of the net cash  proceeds  of one or more  Public  Equity  Offerings;
provided that at least  $300,000,000  aggregate  principal  amount of Securities
originally  issued  remains   outstanding  after  the  occurrence  of  any  such
redemption  and that any such  redemption  occurs  within 60 days  following the
closing of any such Public Equity Offering.

     6. Right to Require  Repurchase.  Following the occurrence of any Change in
Control,  each Holder will have the right to require that the Company repurchase
(a "Change in Control  Repurchase") such Holder's Securities at a purchase price
equal to 101% of the aggregate principal amount of the Securities,  plus accrued
and unpaid interest thereon,  if any, to the date of repurchase.  Within 30 days
after any Change in  Control,  the  Company or, at the  Company's  request,  the
Trustee, shall cause to be mailed a notice to all Holders notifying such Holders
of the  occurrence of such Change in Control,  the Holder's  rights arising as a
result thereof and the procedures to be followed by Holders  wishing to exercise
such rights.

     A Holder  of  Securities  may  exercise  the  right to  require a Change in
Control  Repurchase  after  receipt of notice of the  existence of such right by
completing the form entitled  "OPTION OF HOLDER TO ELECT PURCHASE"  appearing on
this  Security  and by  complying  with the other  procedures  set forth in such
notice.  Any portion of  Securities  with respect to which the Holder  wishes to
exercise such right must be in integral multiples of $1,000.

     7. Mandatory Offer to Repurchase.  If the Company consummates an Asset Sale
(as such term is defined in the  Indenture),  the  Company  may,  under  certain
circumstances,  be  required to utilize a portion of the net  proceeds  received
from such Asset Sale to offer to purchase  Securities at a purchase  price equal
to 100% of the  aggregate  principal  amount  of the  Securities,  plus  accrued
interest to the date fixed for redemption  (the "Asset Sale Offer").  Holders of
Securities  that are the subject of an offer to purchase  will  receive an Asset
Sale Offer from the Company or the  Trustee.  The Asset Sale Offer shall  remain
open for a period of 30 days  after its  commencement  unless a longer  offering
period is required by law (the  "Asset Sale Offer  Period").  On or prior to the
fifth Business Day following the termination of the Asset Sale Offer Period (the
"Asset Sale Payment Date"), the Company shall purchase,  or cause the Trustee to
purchase,  and mail or deliver payment for the amount of Securities  required to
be  purchased  pursuant  to the Asset  Sale Offer or, if less than the amount of
Securities  required to be  purchased  pursuant to the Asset Sale Offer has been
tendered, all Securities tendered in response to the Asset Sale Offer

     A Holder of  Securities  may tender or refrain  from  tendering  all or any
portion of his  Securities at his  discretion  by  completing  the form entitled
"OPTION OF HOLDER TO ELECT PURCHASE" appearing on this Security.  Any portion of
Securities tendered must be in integral multiples of $1,000.

     8. Notice of  Redemption.  Notice of Redemption  will be mailed at least 30
days but not more than 60 days  before  the  redemption  date to each  Holder of
Securities to be redeemed at his registered address. Securities in denominations
larger  than  $1,000  may be  redeemed  in part but only in whole  multiples  of
$1,000, unless all of the Securities held by a Holder are to be redeemed. On and
after the  redemption  date  interest  will  cease to accrue  on  Securities  or
portions  thereof  called for  redemption  (unless the  Company  defaults on its
obligation to repurchase Securities).

     9.  Subordination.  The indebtedness  evidenced by this Security is, to the
extent provided in the Indenture, subordinate and subject in right of payment to
the  prior  payment  in full  of all  Senior  Indebtedness  (as  defined  in the
Indenture),  and this  Security  is  issued  subject  to the  provisions  of the
Indenture with respect thereto.  Each


                                      B-4


Holder of this Security, by accepting the same, (a) agrees to and shall be bound
by such provisions, (b) authorizes and directs the Trustee on his behalf to take
such action as may be necessary or appropriate  to effectuate the  subordination
so provided,  and (c) appoints the Trustee his  attorney-in-fact for any and all
such purposes.

     10.  Denominations,  Transfer,  Exchange.  The Securities are in registered
form  without  coupons in  denominations  of $1,000 and  integral  multiples  of
$1,000.  The transfer of Securities  may be  registered  and  Securities  may be
exchanged  as  provided  in the  Indenture.  The  Registrar  and the Trustee may
require a Holder,  among other things, to furnish  appropriate  endorsements and
transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture.

     11.  Persons  Deemed  Owners.  The  registered  Holder of a Security may be
treated as its owner for all purposes.

     12. Amendments and Waivers. Subject to certain exceptions, the Indenture or
the Securities may be amended or supplemented with the consent of the Holders of
at least a majority in principal amount of the Securities then outstanding,  and
any existing  default under,  or compliance with any provision of, the Indenture
may be waived  (other  than any  continuing  Default  or Event of Default in the
payment of interest or premium, if any, on or the principal of the Securities or
in respect of a  provision  under the  Indenture  which  cannot be  modified  or
amended  without the consent of the Holder of each  Security  then  outstanding)
with the  consent  of the  Holders  of a  majority  in  principal  amount of the
Securities then outstanding.  Without the consent of any Holder, the Company and
the Trustee may amend or supplement  the Indenture or the  Securities to provide
for the  assumption  of the  Company's  obligations  to Holders in the case of a
merger or acquisition; to evidence and provide for the acceptance of appointment
of any successor Trustee under the Indenture; to comply with the requirements of
the Trust  Indenture  Act of 1939,  as amended;  to add to the  covenants of the
Company for the benefit of the Holders or an  additional  Event of Default or to

under the  Indenture;  secure the  Securities  or provide for any Guarantee by a
Subsidiary;  to provide for the issuance of securities identical in all material
respects  to the  Securities  pursuant  to the  Exchange  Offer;  or to cure any
ambiguity,  correct  or  supplement  any  provision  which may be  defective  or
inconsistent  with any other provision in the Indenture,  or make any provisions
with respect to matters or questions arising under the Indenture which shall not
be  inconsistent  with the  provisions  of the  Indenture,  provided  that  such
modification  or  amendment  does not  adversely  affect  the  interests  of the
holders.

     The right of any Holder to  participate  in any consent  required or sought
pursuant to any provision of the Indenture (and the obligation of the Company to
obtain any such consent  otherwise  required from such Holder) may be subject to
the  requirement  that such  Holder  shall have been the Holder of record of any
Securities with respect to which such consent is required or sought as of a date
identified by the Trustee in a notice  furnished to Holders in  accordance  with
the terms of the Indenture.

     Without  the consent of each Holder  affected,  the Company may not,  among
other  things,  (i) change  the  Stated  Maturity  of the  principal  of, or any
installment of interest on, any Security,  (ii) reduce the principal  amount of,
or premium,  if any, or interest  on, any  Security,  (iii)  change the place of
payment where, or the coin or currency in which,  any Security or any premium or
interest thereon is payable, (iv) impair the right of a Holder to institute suit
for the  enforcement  of payment of the  principal of and  premium,  if any, and
interest on any Security on or after the Stated Maturity thereof (or in the case
of a redemption,  on or after the redemption  date) or (v) reduce the percentage
in principal  amount of Securities  the consent of whose Holders is required for
any modification or amendment of the Indenture,  or the consent of whose Holders
is  required  for any  waiver  of  compliance  with  certain  provisions  of the
Indenture or certain Defaults or Events of Default thereunder.

     Without the consent of at least 66_% of the aggregate  principal  amount of
outstanding  Securities,  the  Company  may not (i) amend,  change or modify the
provisions of Article Three of the Indenture relating to the optional redemption
of the  Securities by the Company in accordance  with Section 3.7 thereof,  (ii)
amend,  change or modify the obligations of the Company with respect to a Change
in Control Repurchase pursuant to Section 4.10 of the Indenture or modify any of
the  provisions or  definitions  relating  thereto or (iii) modify or change any
provision  of the  Indenture  affecting  the  subordination  or  ranking  of the
Securities in a manner adverse to Holders of the Securities.

     13.  Defaults  and  Remedies.  Events of Default  include:  (i)  default in
payment of  principal or premium on the  Securities;  (ii) default in payment of
interest on the Securities for 30 days; (iii) failure by the Company for 45 days
after notice to it to comply with any of its other  agreements  in the Indenture
or the Securities;  (iv) any


                                      B-5


acceleration  of  Indebtedness  of the  Company  or its  Subsidiaries  having an
outstanding principal amount of $10 million in the aggregate or a failure to pay
such  Indebtedness at its stated maturity if such acceleration or failure to pay
is not cured  within 10 days of such  acceleration  or failure  to pay;  and (v)
certain events of bankruptcy or insolvency. If an Event of Default occurs and is
continuing,  the Trustee or the Holders of at least 25% in  aggregate  principal
amount of the then  outstanding  Securities may declare all the Securities to be
immediately due and payable for an amount equal to 100% of the principal  amount
of the  Securities,  and premium,  if any, plus accrued  interest to the date of
payment,  except that in the case of an Event of Default  arising  from  certain
events of bankruptcy or insolvency,  all outstanding  Securities  become due and
payable  immediately  without further action or notice.  Holders may not enforce
the Indenture or the Securities except as provided in the Indenture. The Trustee
may require indemnity satisfactory to it before it enforces the Indenture or the
Securities.  Subject to certain limitations,  Holders of a majority in principal
amount of the then outstanding Securities may direct the Trustee in its exercise
of any trust or power.  The  Trustee may  withhold  from  Holders  notice of any
continuing default (except a default in payment of principal or interest or that
resulted  from the failure of the Company to comply  with its  obligations  with
respect to Holders' rights to require  repurchase of Securities upon a Change in
Control) if it determines that  withholding  notice is in their  interests.  The
Company must furnish an annual compliance certificate to the Trustee.

     14. Trustee  Dealings with Company.  The Trustee,  in its individual or any
other capacity,  may make loans to, accept  deposits from, and perform  services
for the Company or its  Affiliates,  and may otherwise  deal with the Company or
its Affiliates, as if it were not Trustee.

     15.  No  Recourse  Against  Others.  A  director,   officer,   employee  or
stockholder,  as such,  of the  Company  shall  not 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 Holder by  accepting  a Security  waives and  releases  all such
liability. The waiver and release are part of the consideration for the issuance
of the Securities.

     16. ERISA Matters.  Each Holder of Securities,  by its acceptance  thereof,
will be deemed to certify  that (i) no part of the funds used by such  Holder to
purchase the Securities  constitutes  assets of an employee benefit plan or (ii)
the  acquisition  and continued  holding of the Securities  will be covered by a
U.S.   Department  of  Labor  class   exemption   (with  respect  to  prohibited
transactions set forth under Section 406(a) of ERISA).

     17. Authentication. This Security shall not be valid until authenticated by
the manual signature of the Trustee or an authenticating agent.

     18.  Abbreviations.  Customary  abbreviations  may be used in the name of a
Holder  or an  assignee,  such  as:  TEN  COM  (--tenants  in  common),  TEN ENT

survivorship  and not as tenants in  common),  CUST  (--Custodian),  and U/G/M/A
(--Uniform Gifts to Minors Act).


     The Company  will  furnish to any Holder upon  written  request and without
charge a copy of the Indenture. Request may be made to:
