Item 1.01.    Entry into a Material Definitive Agreement.


Indenture
---------

         On May 27, 2005, Thermo Electron Corporation, a Delaware corporation
(the "Company"), entered into an indenture (the "Indenture") with JPMorgan Chase
Bank, N.A., as trustee, relating to the Company's 5% Senior Notes due 2015 (the
"Notes"). The information set forth in Item 2.03 below with respect to the Notes
is incorporated herein by reference in its entirety.

         The Indenture contains limited affirmative and negative covenants of
the Company. The negative covenants restrict the ability of the Company (and
certain designated subsidiaries) to incur debt secured by liens, engage in sale
and lease-back transactions and merge or consolidate or sell all or
substantially all of its assets.

         Upon the occurrence of an event of default under the Indenture, which
includes payment defaults, defaults in the performance of affirmative and
negative covenants, bankruptcy and insolvency related defaults and failure to
pay certain indebtedness, the obligations of the Company under the Notes may be
accelerated, in which case the principal of, premium, if any, and accrued and
unpaid interest, if any, on the Notes would be immediately due and payable.

         The foregoing description of certain of the terms of the Indenture does
not purport to be complete and is qualified in its entirety by reference to the
full text of the Indenture, which is filed with this report as Exhibit 99.1 and
is incorporated herein by reference.

Registration Rights Agreement
-----------------------------

         In connection with the completion of the issuance and sale of the
Notes, the Company also entered into Registration Rights Agreement, dated as of
May 27, 2005 (the "Registration Rights Agreement"), with the Initial Purchasers
(as defined in Item 2.03 below).

         The Registration Rights Agreement requires the Company to, among other
things: (a) file a registration statement with the Securities and Exchange
Commission (the "SEC") under the Securities Act of 1933, as amended (the
"Securities Act") relating to a registered exchange offer for the Notes under
the Securities Act within 90 days after the date of issuance of the Notes, (b)
cause the exchange offer registration statement to be declared effective under
the Securities Act within 180 days after the date of issuance of the Notes, and
(c) cause the exchange offer to be consummated on or before 210 days after the
date of issuance of the Notes. The exchange notes would have substantially the
same terms as the Notes.

         If the exchange offer is not consummated by December 23, 2005 or, in
certain limited circumstances, an initial purchaser of the Notes so requests,
the Company has agreed to use its reasonable best efforts to file as soon as
reasonably practicable after such date or request, as the case may be, a shelf
registration statement with the SEC to cover resales of the Notes.

         If the Company is unable to meet its registration obligations under the
Registration Rights Agreement, the Company will be obligated to pay additional
interest to each holder of the Notes in an amount equal to 0.25% per year for
the first 90-day period (or portion thereof) during which such registration
obligations have not been met, which rate will be increased by 0.25% per year at
the beginning of the subsequent 90-day period and continue until the Company is
able to meet its registration obligations under the Registration Rights
Agreement or the Notes become freely tradable under the Securities Act. The
maximum aggregate increase in the interest rate will in no event exceed 0.50%
per year.

                                       2



         The foregoing description of certain of the terms of the Registration
Rights Agreement does not purport to be complete and is qualified in its
entirety by reference to the full text of the Registration Rights Agreement,
which is filed with this report as Exhibit 99.2 and is incorporated herein by
reference.

Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an
Off-Balance Sheet Arrangement of a Registrant. 

5% Senior Notes
---------------

         As previously announced, the Company entered into an agreement on May
24, 2005 to issue and sell $250 million in aggregate principal amount of the
Notes. The press release announcing the pricing of the Notes was filed with the
SEC on May 25, 2005 as Exhibit 99.1 to the Company's Current Report on Form 8-K.
On May 27, 2005, the Company completed the issuance and sale of $250 million
aggregate principal amount of the Notes to J.P. Morgan Securities Inc., Barclays
Capital Inc., ABN AMRO Incorporated, Banc of America Securities LLC, KeyBanc
Capital Markets, a Division of McDonald Investments Inc., and Mitsubishi
Securities International plc. (each, an "Initial Purchaser" and collectively,
the "Initial Purchasers").

         The Notes were issued under the Indenture described in Item 1.01 of
this current report, which description is incorporated herein by reference. The
Notes accrue interest at 5% per year, payable semi-annually in arrears on June 1
and December 1 of each year, beginning on December 1, 2005. The Notes mature on
June 1, 2015 unless redeemed prior to such date. The Company may redeem the
Notes in whole or in part, at its option, at any time prior to their maturity,
at a redemption price equal to the greater of (1) 100% of the principal amount
of the Notes being redeemed and (2) the sum of the present values of the
remaining scheduled payments of principal and interest thereon (exclusive of
interest accrued to the date of redemption) discounted to the redemption date on
a semi-annual basis at a comparable treasury rate plus 15 basis points, plus
accrued interest thereon to the redemption date.

         The Notes are senior unsecured obligations of the Company that rank
equally with the Company's other existing and future unsecured and
unsubordinated debt.

         The net proceeds of the Notes offering and cash on hand have been used
to repay $250 million of the amount outstanding under the Company's 364-Day
Credit Agreement, dated May 9, 2005, among the Company, the several banks and
other financial institutions or entities from time to time parties thereto,
JPMorgan Chase Bank, N.A., as Administrative Agent, Barclays Bank PLC, as
Syndication Agent, and ABN AMRO Bank, N.V., as Documentation Agent (the "Bridge
Facility"), which the Company entered into in connection with its acquisition of
the Kendro Laboratory Products division of SPX Corporation.

         The foregoing description of the terms of the Notes does not purport to
be complete and is qualified in its entirety by reference to the full text of
the Indenture, including the Form of Note attached as Exhibit A to the
Indenture, filed with this current report as Exhibit 99.1.

Money Market Note
-----------------

         In addition, on May 27, 2005 the Company executed a Fixed Rate
Promissory Note (Multiple Loans) (the "Money Market Loan Program") in favor of
JPMorgan Chase Bank, N.A. (the "Bank"), which provides the Company with an
uncommitted line of credit of up to $250 million in aggregate principal amount
through a series of short-term money market loans funded on an ongoing basis in
the secondary market. Such money market loans will have maturity periods ranging
from overnight to 364 days and will bear varying rates of interest based on the
maturity date and market rates at the time of issuance. Each loan may be prepaid
in whole or in part, provided that accrued and unpaid interest is paid on the
date of such prepayment, together with any compensation as will be sufficient in
the reasonable 

                                       3



opinion of the Bank to compensate it for any loss, cost or expense that the 
Bank determines is attributable to such early repayment.

         The obligations of the Company under any such money market loans may be
accelerated upon the occurrence of an event of default under the Money Market
Loan Program, which includes customary events of default including, without
limitation, payment defaults, defaults in the performance of material covenants,
bankruptcy and insolvency related defaults, uninsured judgments, the failure to
pay certain indebtedness and unwaived defaults under the Company's existing Five
Year Credit Agreement, dated as of December 17, 2004, by and among the Company
and Barclays Bank PLC, as Administrative Agent, ABN AMRO Bank N.V., as
Syndication Agent, Bank of America, N.A. and JPMorgan Chase Bank, N.A., as
Co-Documentation Agents, and the several banks and other financial institutions
from time to time party thereto.

         On May 27, 2005, the Company borrowed $250 million under the Money
Market Loan Program through three short-term money market loans with terms
ranging from a week to three months at an average interest rate of 3.31%. The
Company expects to continuously refinance the money market loans as they come
due with new short-term money market loans under the Money Market Loan Program.
The aggregate amount borrowed under the Money Market Loan Program has been used
to repay an additional $250 million of the amount outstanding under the Bridge
Facility.

     (iii) Members of, or participants  in, DTC ("Agent  Members") shall have no
rights under this Indenture with respect to any Global Note held on their behalf
by DTC or by the Trustee as the custodian of DTC or under such Global Note,  and
DTC may be treated by the  Company,  the Trustee and any agent of the Company or
the  Trustee  as the  absolute  owner  of such  Global  Note  for  all  purposes
whatsoever.  Notwithstanding  the  foregoing,  nothing  herein shall prevent the
Company,  the  Trustee or any agent of the  Company or the  Trustee  from giving
effect to any written certification,  proxy or other authorization  furnished by
DTC or impair, as between DTC and its Agent Members,  the operation of customary
practices  of  DTC  governing  the  exercise  of the  rights  of a  holder  of a
beneficial interest in any Global Note.

     (iv) In  connection  with  any  transfer  of a  portion  of the  beneficial
interest in a Global Note pursuant to Section 2.1(e) into Definitive  Notes, the
Securities  Custodian  shall  reflect  on its books and  records  the date and a
decrease in the  principal  amount of such Global Note in an amount equal to the
principal  amount  of  the  beneficial   interest  in  the  Global  Note  to  be
transferred,  and the Company shall execute,  and the Trustee shall authenticate
and deliver, one or more Definitive Notes of like tenor and amount.

     (v) In connection  with the transfer of an entire Global Note to beneficial
owners pursuant to subsection (e) of this Section 2.1, such Global Note shall be

authorize  any  person,  including  Agent  Members  and  persons  that  may hold
interests  through Agent Members,  to take any action which a Holder is entitled
to take under this Indenture or the Notes.

     (e) Definitive  Notes.  (i) Owners of beneficial  interests in Global Notes
shall not be entitled to receive certificated Notes ("Definitive Notes"), unless
(a) DTC  notifies  the  Company  that it is  unwilling  or unable to continue as
depositary for such Global Note or DTC ceases to be a clearing agency registered
under the Exchange  Act, at a time when DTC is required to be so  registered  in
order to act as  depositary,  and in each  case a  successor  depositary  is not
appointed  by the  Company  within 90 days of such  notice or,  (b) the  Company
executes  and delivers to the Trustee and  Registrar  an  Officers'  Certificate
stating  that  such  Global  Note  shall be so  exchangeable  or (c) an Event of
Default has occurred and is continuing  and the Registrar has received a request
from DTC.

                                                                              12

     (ii) Any Definitive  Note delivered in exchange for an interest in a Global

provided  by Section  2.6(g),  bear the  applicable  legend  regarding  transfer
restrictions applicable to the Definitive Note set forth in Section 2.1(c).

     SECTION 2.2. Execution and Authentication.  An Officer of the Company shall
sign the Notes for the  Company  by manual  or  facsimile  signature  and may be
imprinted or otherwise reproduced.

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

     A Note shall not be valid  until an  authorized  signatory  of the  Trustee
manually authenticates the Note. The signature of the Trustee on a Note shall be
conclusive  evidence that such Note has been duly and validly  authenticated and
issued under this Indenture.

     At any time and from time to time after the  execution and delivery of this
Indenture,  the Trustee shall authenticate and make available for delivery:  (1)
Initial  Notes for original  issue on the Issue Date in an  aggregate  principal
amount of $250 million, (2) any Additional Notes for original issue from time to
time after the Issue Date in such principal amounts as set forth in Section 2.15
and (3) any  Exchange  Notes for issue  only in  exchange  for a like  principal
amount of Initial Notes, in each case upon a written order of the Company signed
by two Officers of the Company (a "Company  Order").  Such  Company  Order shall
specify  the amount of the Notes to be  authenticated  and the date on which the
original issue of Notes is to be  authenticated  and whether the Notes are to be
Initial Notes or Exchange Notes. The aggregate principal amount of Initial Notes
which may be authenticated and delivered under this Indenture shall initially be
limited  to  $250,000,000.  Additionally,  the  Company  may from  time to time,
without  notice to or consent of the Holders,  issue such  additional  principal
amounts of  Additional  Notes as may be issued  and  authenticated  pursuant  to
clause  (2) of this  paragraph,  and  Notes  authenticated  and  delivered  upon
registration  or transfer of, or in exchange  for, or in lieu of, other Notes of
the same class pursuant to Section 2.6, Section 2.9, Section 2.10,  Section 3.6,
Section 9.5.

     The Trustee may appoint an agent (the  "Authenticating  Agent")  reasonably
acceptable to the Company to authenticate the Notes. Unless limited by the terms
of such  appointment,  any such  Authenticating  Agent  may  authenticate  Notes
whenever  the  Trustee  may  do  so.  Each   reference  in  this   Indenture  to
authentication by the Trustee includes authentication by such agent.

     In case the Company, pursuant to Article V, shall be consolidated or merged
with or into any other  Person or shall  convey,  transfer,  lease or  otherwise
dispose of its properties and assets substantially as an entirety to any Person,
and the successor  Person resulting from such  consolidation,  or surviving such
merger,  or into which the Company  shall have been merged,  or the Person which
shall have  received  a  conveyance,  transfer,  lease or other  disposition  as
aforesaid,  shall  have  executed  an  indenture  supplemental  hereto  (if  not
otherwise a party to the Indenture) with the Trustee  pursuant to Article V, any
of the Notes  authenticated  or delivered prior to such  consolidation,  merger,
conveyance,  transfer, lease or other disposition may, from 


                                                                              13

time to time,  at the request of the  successor  Person,  be exchanged for other
Notes  executed  in the  name of the  successor  Person  with  such  changes  in
phraseology and form as may be  appropriate,  but otherwise in substance of like
tenor as the Notes  surrendered for such exchange and of like principal  amount;
and the Trustee,  upon Company Order of the successor Person, shall authenticate
and deliver  Notes as specified in such order for the purpose of such  exchange.
If Notes shall at any time be  authenticated  and delivered in any new name of a
successor  Person (if other than the  Company)  pursuant to this  Section 2.2 in
exchange or substitution for or upon registration of transfer of any Notes, such
successor  Person (if other than the Company),  at the option of the Holders but
without expense to them, shall provide for the exchange of all Notes at the time
outstanding for Notes authenticated and delivered in such new name.

     SECTION  2.3.Registrar  and Paying  Agent.  The Company  shall  maintain an
office or agency where Notes may be presented  for  registration  of transfer or
for  exchange  (the  "Registrar")  and an office or  agency  where  Notes may be
presented for payment (the "Paying Agent").  The Registrar shall keep a register
of the Notes and of their  transfer  and  exchange.  The Company may have one or
more  additional  paying  agents.  The term  "Paying  Agent"  includes  any such
additional  paying agent. The Company may change the Registrar or appoint one or
more co-Registrars without notice.

     In the  event the  Company  shall  retain  any  Person  not a party to this
Indenture as an agent  hereunder,  the Company  shall enter into an  appropriate
agency  agreement  with  any  Registrar  or  Paying  Agent  not a party  to this
Indenture,  which shall  incorporate  the terms of the Trust  Indenture Act. The
agreement  shall  implement the provisions of this Indenture that relate to such
agent. The Company shall notify the Trustee of the name and address of each such
agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee
shall act as such and shall be entitled  to  appropriate  compensation  therefor
pursuant to Section  7.7.  The  Company  shall be  responsible  for the fees and
compensations  of all agents  appointed or approved by it. Either the Company or
any of its domestically incorporated wholly owned Subsidiaries may act as Paying
Agent.

     The Company  initially  appoints the Trustee as Registrar  and Paying Agent
for the Notes.

     SECTION 2.4.  Paying  Agent To Hold Money in Trust.  By no later than 10:00
a.m.  (New  York  City  time) on the date on which  any  principal  or  interest
(including any Additional  Interest) on any Note is due and payable, the Company
shall deposit with the Paying Agent a sum  sufficient  to pay such  principal or
interest (including any Additional Interest) when due. The Company shall require
each Paying  Agent (other than the Trustee) to agree in writing that such Paying
Agent  shall hold in trust for the  benefit of  Noteholders  or the  Trustee all
money held by such  Paying  Agent for the  payment of  principal  of or interest
(including any Additional Interest) on the Notes and shall notify the Trustee in
writing of any default by the Company in making any such  payment.  If either of
the Company or any of its Subsidiaries  acts as Paying Agent, it shall segregate
the money held by it as Paying Agent and hold it as a separate  trust fund.  The
Company at any time may require a Paying  Agent  (other than the Trustee) to pay
all money held by it to the Trustee and to account  for any funds  disbursed  by
such Paying Agent.  Upon  complying  with this Section 2.4, the Paying Agent (if
other than the Company or a Subsidiary)  shall have no further liability for the
money delivered to the Trustee.  Upon any 

                                                                              14

bankruptcy,  reorganization  or similar  proceeding with respect to the Company,
the Trustee shall serve as Paying Agent for the Notes.

     SECTION 2.5.  Noteholder  Lists. The Trustee shall preserve in as current a
form as is reasonably  practicable  the most recent list  available to it of the
names and addresses of  Noteholders.  If the Trustee is not the  Registrar,  the
Company shall cause the Registrar to furnish to the Trustee, in writing at least
five Business Days before each interest  payment date and at such other times as
the Trustee  may request in writing,  a list in such form and as of such date as
the Trustee may reasonably require of the names and addresses of Noteholders.

     SECTION 2.6. Transfer and Exchange.

     Notwithstanding  any other  provision of this Indenture or the Notes (other
than Section  2.1(e)  hereof),  transfers and exchanges of Notes and  beneficial
interests  in a Global Note of the kinds  specified in this Section 2.6 shall be
made only in accordance with this Section 2.6.

     (a) Rule 144A Global Note to  Regulation S Global  Note.  If the owner of a
beneficial  interest in the Rule 144A Global Note wishes at any time to transfer
such interest to a person who wishes to take  delivery  thereof in the form of a
beneficial  interest in the  Regulation  S Global  Note,  such  transfer  may be

authorized in writing,  in which case the transferee  holder shall take delivery

duly  authorized  in writing,  in which case the  transferee  holder  shall take
delivery  in the form of a  Regulation  S Note  (subject in each case to Section
2.6(g)).

     (f) Exchange between Global Note and Non-Global Note. A beneficial interest
in a  Global  Note may be  exchanged  for a Note  that is not a  Global  Note as
provided in Section  2.1(e);  provided,  that if such  interest is a  beneficial
interest in (I) the Rule 144A Global Note or (II) the  Regulation  S Global Note
and such exchange is to occur during the Restricted Period,  then, in each case,
such  interest  shall be exchanged for a Rule 144A Note (subject in each case to
Section  2.6(g)).  A Note  that is not a  Global  Note  may be  exchanged  for a
beneficial  interest  in a Global  Note  only if (A)  such  exchange  occurs  in
connection with a transfer  effected in accordance with Section 2.6(c) or 2.6(d)
herein or (B) such Note is a  Regulation S Note and such  exchange  occurs after
the Restricted Period.

     (g) Restrictive Notes Legend.  Upon the registration of transfer,  exchange
or  replacement of Notes not bearing a Restrictive  Notes Legend,  the Registrar
shall  deliver  Notes  that do not bear a  Restrictive  Notes  Legend.  Upon the
registration of transfer, exchange or replacement of Notes bearing a Restrictive
Notes  Legend,  the  Registrar  shall deliver only Notes that bear a Restrictive
Notes Legend unless there is delivered to the Registrar an Opinion of Counsel to
the effect that neither such legend nor the related restrictions on transfer are
required in order to maintain  compliance  with the provisions of the Securities
Act.

     (h) The  Company  shall  deliver to the  Trustee an  Officers'  Certificate
setting forth the Resale Restriction Termination Date and the Restricted Period.

     The Registrar shall retain copies of all letters, notices and other written
communications received pursuant to Section 2.1 or this Section 2.6. The Company
shall have the right to inspect and make copies of all such letters,  notices or
other  written  communications  at  any  reasonable  time  upon  the  giving  of
reasonable written notice to the Registrar.

     (i) Obligations with Respect to Transfers and Exchanges of Notes.

          (i) To permit  registrations  of transfers and exchanges,  the Company
     shall,  subject  to the other  terms and  conditions  of this  Article  II,
     execute  and the Trustee  shall  authenticate  Definitive  Notes and Global
     Notes at the Registrar's or co-registrar's request.

          (ii) No service charge shall be made to a Holder for any  registration
     of transfer or exchange, but the Company or the Trustee may require payment
     of a sum  sufficient  to cover any transfer  tax,  assessments,  or similar
     governmental  charge payable in connection  therewith  (other than any such
     transfer taxes,  assessments or similar  governmental  charges payable upon
     exchange or transfer pursuant to Sections 3.6 or 9.5).

          (iii) The Registrar or co-registrar  shall not be required to register
     the transfer of or exchange of any Note for a period  beginning (1) 15 days
     before the mailing of a notice of an offer to  repurchase  or redeem  Notes
     and ending at the close of  business  on the day of such  mailing or (2) 15
     days before an interest  payment date and ending on such  interest  payment
     date.

                                                                              17

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

          (v) Any  Definitive  Note  delivered  in exchange for an interest in a
     Global Note pursuant to Section 2.1(d) shall,  except as otherwise provided
     by  Section  2.6(g),   bear  the  applicable   legend  regarding   transfer
     restrictions applicable to the Definitive Note set forth in Section 2.1(c).

          (vi) All Notes  issued upon any  transfer or exchange  pursuant to the
     terms of this Indenture shall be the valid and legally  binding  obligation
     of the Company,  shall  evidence the same debt and shall be entitled to the
     same  benefits  under this  Indenture  as the Notes  surrendered  upon such
     transfer or exchange.

          (vii)  All  certificates,   certifications  and  opinions  of  counsel
     required to be submitted to the Registrar or any  co-registrar  pursuant to
     this  Section 2.6 to effect any  transfer or exchange  may be  submitted by
     facsimile transmission,  with the original to follow by first class mail or
     hand delivery.

     (j)  No  Obligation  of  the  Trustee.   (i)  The  Trustee  shall  have  no
responsibility  or obligation to any beneficial owner of a Global Note, a member
of, or a  participant  in,  DTC or other  Person in respect of any aspect of the
records, or for maintaining,  supervising or reviewing any records,  relating to
beneficial ownership interests of a Global Note, with respect to the accuracy of
the records of DTC or its nominee or of any participant or member thereof,  with
respect to any  ownership  interest in the Notes or with respect to the delivery
to any participant, member, beneficial owner or other Person (other than DTC) of
any notice  (including any notice of redemption) or the payment of any amount or
delivery of any Notes (or other  security or property)  under or with respect to
such Notes.  All notices and  communications  to be given to the Holders and all
payments  to be made to Holders  in respect of the Notes  shall be given or made
only to or upon the order of the  registered  Holders (which shall be DTC or its
nominee in the case of a Global Note).  The rights of  beneficial  owners in any
Global Note shall be exercised only through DTC subject to the applicable  rules
and  procedures  of DTC. The Trustee and the Company may  conclusively  rely and
shall be fully  protected  in relying  upon  information  furnished  by DTC with
respect to its members, participants and any beneficial owners.

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

                                                                              18

     (k)  Transfer  and  Exchange  of  Global  Notes.  A Global  Note may not be
transferred as a whole except by DTC to a nominee of DTC, by a nominee of DTC to
DTC or to another  nominee of DTC, or by DTC or any such  nominee to a successor
depositary or to a nominee of such successor depositary.

     Neither the Trustee nor any agent thereof shall have any responsibility for
any actions taken or not taken by DTC or any successor depositary.

     (l) Accrual of Interest on the Exchange Note; Exchange of Exchange Notes.
         

          (i) Interest on any Exchange Note shall accrue from the dates provided
     in Exhibit B.

          (ii) Subject to Section 2.1(e),  upon the occurrence of the Registered
     Exchange Offer in accordance with the Registration  Rights  Agreement,  the
     Company  shall  issue  and,  upon  receipt  of an  authentication  order in
     accordance  with Section 2.2, the Trustee  shall  authenticate  one or more
     Exchange  Global  Notes  in an  aggregate  principal  amount  equal  to the
     principal  amount  of the  beneficial  interests  in the  Initial  Notes or
     Additional  Notes  tendered for  acceptance  by Persons that certify in the
     applicable  letters of  transmittal  that (w) any Exchange Note received by
     them are acquired in the ordinary course of their businesses, (x) they will
     deliver a prospectus in connection with any resale of the Exchange Notes if
     they are  broker-dealers,  (y) they are not participating in a distribution
     of the Exchange  Notes and (z) they are not  affiliates (as defined in Rule
     144 under the Securities Act) of the Company,  and accepted for exchange in
     the  exchange  offer.  Concurrently  with the  issuance of such Notes,  the
     Trustee  shall  cause the  aggregate  principal  amount  of the  applicable
     Initial  Notes in the form of Global Notes and/or  Additional  Notes in the
     form of Global Notes to be reduced accordingly.

     SECTION  2.7.  Form of  Certificates  to be Delivered  in  Connection  with
Transfers Pursuant to Regulation S and Rule 144A.

     Attached  hereto as Exhibit C and Exhibit D are forms of certificates to be
delivered in connection  with transfers  pursuant to Regulation S and Rule 144A,
respectively.

     SECTION 2.8.  Business  Days.  If a payment date is on a date that is not a
Business  Day,  payment  shall  be made on the  next  succeeding  day  that is a
Business Day, and no interest  shall accrue on such payment for the  intervening
period.  If a regular  record date is on a day that is not a Business  Day,  the
record date shall not be affected.

     SECTION 2.9.  Replacement  Notes. If a mutilated Note is surrendered to the
Registrar  or if the Holder of a Note shall  provide the Company and the Trustee
with evidence to their  satisfaction  that the Note has been lost,  destroyed or
wrongfully  taken, the Company shall issue and the Trustee shall  authenticate a
replacement Note if the requirements of Section 8-405 of the Uniform  Commercial
Code are met and the Holder satisfies any other  reasonable  requirements of the
Trustee.  In  addition,  such Holder  shall  furnish an indemnity or surety bond
sufficient  in the  judgment  of the  Company  and the  Trustee to  protect  the
Company, the Trustee, the Paying Agent and the Registrar from any loss which any
of them may suffer if a Note is 




                                                                              19

replaced.  The Company and the Trustee may charge the Holder for their  expenses
in replacing a Note,  including  reasonable fees and expenses of counsel.  Every
replacement Note is an additional obligation of the Company.

     SECTION 2.10.  Outstanding  Notes.  Notes  outstanding  at any time are all
Notes  authenticated  by the Trustee except for those canceled,  those delivered
for cancellation and those described in this Section 2.10 as not outstanding.  A
Note does not cease to be outstanding because the Company or an Affiliate of the
Company holds the Note.

     If a Note is replaced  pursuant to Section 2.9, it ceases to be outstanding
unless the Trustee and the Company  receive proof  satisfactory to them that the
replaced Note is held by a protected purchaser.

     If the Paying Agent  segregates and holds in trust, in accordance with this
Indenture,  on a redemption  date or maturity  date money  sufficient to pay all
principal  and  interest  payable  on that  date with  respect  to the Notes (or
portions  thereof) to be redeemed or  maturing,  as the case may be, then on and
after that date such Notes (or portions  thereof)  cease to be  outstanding  and
interest on them ceases to accrue.

     SECTION  2.11.  Temporary  Notes.  Until  Definitive  Notes  are  ready for
delivery, the Company may prepare and the Trustee shall authenticate and deliver
temporary  Notes.  Temporary  Notes  shall  be  substantially  in  the  form  of
Definitive Notes but may have variations that the Company considers  appropriate
for temporary Notes.  Without  unreasonable delay, the Company shall prepare and
the  Trustee  shall   authenticate  and  deliver  Definitive  Notes.  After  the
preparation of Definitive  Notes,  the temporary Notes shall be exchangeable for
Definitive  Notes upon surrender of the temporary  Notes at any office or agency
maintained  by the Company for that purpose and such  exchange  shall be without
charge  to the  Holder.  Upon  surrender  for  cancellation  of any  one or more
temporary Notes, the Company shall execute,  and the Trustee shall  authenticate
and deliver in exchange  therefor,  one or more Definitive Notes representing an
equal  principal  amount of Notes.  Until so exchanged,  the Holder of temporary
Notes  shall in all  respects  be  entitled  to the  same  benefits  under  this
Indenture as a Holder of Definitive Notes.

     SECTION  2.12.  Cancellation.  The Company at any time may deliver Notes to
the Trustee for  cancellation.  The Registrar and the Paying Agent shall forward
to the Trustee for cancellation  any Notes  surrendered to them for registration
of transfer or  exchange  or payment.  The Trustee and no one else shall  cancel
(subject to the record  retention  requirements  of the Exchange  Act) all Notes
surrendered for  registration  of transfer or exchange,  payment or cancellation
and, upon the request of the Company, deliver a certificate of such cancellation
to the  Company.  The  Company  may not issue new Notes to replace  Notes it has
redeemed,  paid or  delivered to the Trustee for  cancellation,  which shall not
prohibit the Company from issuing any Additional Notes, or any Exchange Notes in
exchange  for  Initial  Notes.  All  cancelled  Notes held by the Trustee may be
disposed of by the Trustee in accordance  with its then customary  practices and
procedures,  unless the Company directs otherwise in writing.  The Trustee shall
provide to the Company a list of all Notes that have been cancelled from time to
time as requested in writing by the Company.


                                                                              20

     SECTION 2.13.  Defaulted Interest.  If the Company defaults in a payment of
interest on the Notes, the Company shall pay defaulted interest plus interest on
such defaulted  interest to the extent lawful at the rate specified  therefor in
the Notes in any lawful  manner.  The Company may pay the defaulted  interest to
the Persons who are Noteholders on a subsequent special record date. The Company
shall fix or cause to be fixed any such special  record date and payment date to
the reasonable satisfaction of the Trustee which specified record date shall not
be less than 10 days prior to the payment date for such  defaulted  interest and
shall  promptly  mail or cause to be mailed  to each  Noteholder  a notice  that
states the special  record  date,  the payment  date and the amount of defaulted
interest  to be paid.  The  Company  shall  notify the Trustee in writing of the
amount of  defaulted  interest  proposed to be paid on each Note and the date of
the proposed  payment,  and at the same time the Company  shall deposit with the
Trustee an amount of money equal to the aggregate  amount proposed to be paid in
respect of such defaulted  interest or shall make  arrangements  satisfactory to
the Trustee for such  deposit  prior to the date of the proposed  payment,  such
money  when so  deposited  to be held in trust  for the  benefit  of the  Person
entitled to such defaulted interest as provided in this Section 2.13.

     SECTION 2.14. CUSIP Numbers,  etc. The Company in issuing the Notes may use
"CUSIP" or "ISIN"  numbers  and/or other similar  numbers (if then  generally in
use), and, if so, the Trustee shall use "CUSIP" and/or "ISIN" numbers in notices
of redemption or exchange as a convenience to Holders;  provided,  however, that
any such notice may state that no  representation  is made as to the correctness
of such numbers  either as printed on the Notes or as contained in any notice of
a  redemption  or  exchange  and that  reliance  may be placed only on the other
identification numbers printed on the Notes, and any such redemption or exchange
shall not be affected by any defect in or omission of such numbers.  The Company
shall promptly  notify the Trustee in writing of any change in the CUSIP numbers
and/or other similar numbers.

     SECTION 2.15.  Issuance of Additional  Notes. The Company shall be entitled
to issue,  from time to time,  Additional Notes under this Indenture which shall
have  identical  terms as the  Initial  Notes  issued on the  Issue  Date or the
Exchange Notes exchanged  therefor (in each case, other than with respect to the
date of  issuance,  issue  price and  amount of  interest  payable  on the first
payment date applicable thereto), as the case may be.

     With  respect to any  Additional  Notes,  the Company  shall set forth in a
resolution  of the Board of Directors  and an Officers'  Certificate,  a copy of
each shall be delivered to the Trustee, the following information:

     (i)  the  aggregate  principal  amount  of  such  Additional  Notes  to  be
authenticated and delivered pursuant to this Indenture;

     (ii) the issue price,  the issue date and the "CUSIP" and "ISIN"  number of
any such  Additional  Notes and the  amount  of  interest  payable  on the first
payment date applicable thereto;

     (iii) whether such Additional Notes shall be transfer restricted securities
and  issued  in the form of  Initial  Notes as set  forth in  Exhibit  A to this
Indenture  or shall be  issued  in the form of  Exchange  Notes as set  forth in
Exhibit B to this Indenture; and

                                                                              21


     (iv)  if  applicable,  the  Resale  Restriction  Termination  Date  and the
Restricted Period for such Additional Notes.

     SECTION 2.16. One Class of Notes.  The Initial Notes,  any Additional Notes
and the  Exchange  Notes shall vote and  consent  together on all matters as one
class;  and none of the Initial  Notes,  any  Additional  Notes and the Exchange
Notes shall have the right to vote or consent as a separate class on any matter.
The Initial Notes, any Additional Notes and the Exchange Notes shall together be
deemed to  constitute  a single  class or series  for all  purposes  under  this
Indenture.

                                  ARTICLE III

                                   Redemption

     SECTION  3.1.  Notices to Trustee.  If the Company  elects to redeem  Notes
pursuant  to Section 5 of the Notes,  it shall  notify the Trustee in writing of
the redemption date and the principal amount of Notes to be redeemed.

     The  Company  shall give each notice to the  Trustee  provided  for in this
Section  3.1 at least 60 days  (45  days in the  case of  redemption  of all the
Notes)  before the  redemption  date  unless the  Trustee  consents to a shorter
period.  Such notice shall be accompanied by an Officers'  Certificate  from the
Company to the effect that such  redemption  shall  comply  with the  conditions
herein.  The record date  relating to such  redemption  shall be selected by the
Company and set forth in the related  notice given to the Trustee,  which record
date shall be not less than 15 days prior to the date selected for redemption by
the Company.

     SECTION 3.2. Selection of Notes to be Redeemed. If fewer than all the Notes
then  outstanding  are to be redeemed,  the Trustee shall select the Notes to be
redeemed by a method that complies with applicable legal and securities exchange
requirements,  if any, and that the Trustee considers, in its discretion,  to be
fair and  appropriate in accordance  with methods  generally used at the time of
selection by  fiduciaries in similar  circumstances.  The Trustee shall make the
selection from  outstanding  Notes not  previously  called for  redemption.  The
Trustee may select for  redemption  portions of the principal of Notes that have
denominations  larger than $5,000.  Notes and portions  thereof that the Trustee
selects shall be in amounts of $5,000 or integral  multiples of $1,000 in excess
thereof.  Provisions of this Indenture that apply to Notes called for redemption
also  apply to  portions  of Notes  called for  redemption.  The  Trustee  shall
promptly notify the Company of the Notes or portions of Notes to be redeemed.

     SECTION 3.3.  Notice of  Redemption.  At least 30 days but not more than 60
days before a date for redemption of Notes, notice of redemption shall be mailed
by  first-class  mail to each Holder of Notes to be  redeemed at its  registered
address.

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

          (1) the redemption date;

                                                                              22


          (2) the redemption  price (or the method of calculating such price) as
     set forth in  Section 5 of the Form of Note in  Exhibit A or B, as the case
     may be, and the amount of accrued interest to be paid, if any;

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

          (4) that Notes called for redemption must be surrendered to the Paying
     Agent to collect the redemption price plus accrued and unpaid interest,  if
     any;

          (5) if fewer than all the  outstanding  Notes are to be redeemed,  the
     Bond No. (if certificated) and principal amounts of the particular Notes to
     be redeemed;

          (6) that,  unless  the  Company  defaults  in making  such  redemption
     payment,  interest  on Notes (or  portion  thereof)  called for  redemption
     ceases to accrue on and after the redemption date;

          (7) the CUSIP number,  or any similar number,  if any,  printed on the
     Notes being redeemed; and

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

     At the Company's  written request (which may be rescinded or revoked at any
time prior to the time at which the Trustee  shall have given such notice to the
Holders),  the Trustee  shall give the notice of  redemption  in the name of the
Company and at the Company's  expense.  In such event, the Company shall provide
the Trustee with the  information  required by this Section 3.3. The notice,  if
mailed in the manner herein  provided,  shall be  conclusively  presumed to have
been given, whether or not the Holder receives such notice. In any case, failure
to give such  notice by mail or any  defect in the  notice to the  Holder of any
Note  designated  for  redemption  as a whole or in part  shall not  affect  the
validity of the proceedings for the redemption of any other Notes.

     SECTION 3.4.  Effect of Notice of Redemption.  Once notice of redemption is
mailed in accordance with Section 3.3, Notes called for redemption  shall become
due and payable on the redemption date and at the redemption  price as stated in

such Notes shall be paid at the  redemption  price  stated in the  notice,  plus
accrued and unpaid interest to the redemption date;  provided,  that the Company
shall have deposited the  redemption  price with the Paying Agent or the Trustee
on or before 10:00 a.m. (New York City time) on the date of redemption; provided
further  that if the  redemption  date is after a regular  record date and on or
prior to the  interest  payment  date,  the  accrued and unpaid  interest  shall
instead be payable to the  Noteholder  of the redeemed  Notes  registered on the
relevant record date.  Failure to give notice or any defect in the notice to any
Holder shall not affect the validity of the notice to any other Holder.

     SECTION 3.5. Deposit of Redemption  Price. By no later than 10:00 a.m. (New
York City time) on the date of  redemption,  the Company  shall deposit with the
Paying Agent (or, if the Company or any of its Subsidiaries is the Paying Agent,
shall  segregate  and hold in trust) 


                                                                              23

unpaid  interest  on all Notes to be  redeemed  on that date other than Notes or
portions  of Notes  called for  redemption  which are owned by the  Company or a
Subsidiary  and have been  delivered  by the Company or such  Subsidiary  to the
Trustee for cancellation.  All money, if any, earned on funds held by the Paying
Agent shall be remitted to the  Company.  In  addition,  the Paying  Agent shall
promptly  return to the Company any money deposited with the Paying Agent by the
Company in excess of the amounts  necessary to pay the redemption  price of, and
accrued interest, if any, on, all Notes to be redeemed.

     Unless  the  Company  defaults  in the  payment of such  redemption  price,
interest on the Notes or portions of Notes to be redeemed  shall cease to accrue
on and after the  applicable  redemption  date,  whether  or not such  Notes are
presented for payment.

     SECTION  3.6.Notes  Redeemed  in Part.  Upon  surrender  of a Note  that is
redeemed in part,  the Company shall execute and the Trustee shall  authenticate
for the  Holder  thereof  (at the  Company's  expense)  a new  Note,  equal in a
principal  amount to the unredeemed  portion of the Note  surrendered;  provided
that each new Note  shall be in a  principal  amount  of  $5,000 or an  integral
multiple of $1,000 in excess thereof.

Subsidiaries is the Paying Agent, the segregated  account or separate trust fund
maintained by the Company or such  Subsidiary  pursuant to Section 2.4) holds in
accordance  with  this  Indenture  money  sufficient  to pay all  principal  and
interest (including Additional Interest) then due. If any Additional Interest is
due, the Company shall deliver an Officers'  Certificate to the Trustee  setting
forth the Additional Interest per $1,000 aggregate principal amount of Notes.

     The Company shall pay interest on overdue principal at the rate of interest
specified  in the Notes,  and it shall pay interest on overdue  installments  of
interest at the same rate to the extent lawful as provided in Section 2.13.

interest payments hereunder.

     consolidated  with the  Company  or a  Subsidiary  or (c) the  Company or a

     Property owned by the Company or such Designated Subsidiary prior thereto;

          (v) Liens on Property to secure any Debt incurred to provide funds for
     all or any  part of the  cost of  development  of or  improvements  to such

     other  disposition  of the Property of a corporation  or other Person as an
     entirety or  substantially  as an  entirety to the Company or a  Designated
     Subsidiary;   provided,  that  such  Lien  as  a  result  of  such  merger,
     consolidation, sale, lease or other disposition is not extended to Property
     owned  by the  Company  or such  Designated  Subsidiary  immediately  prior
     thereto;




                                                                              25

     secured thereby, provided that such extension,  renewal or replacement Lien
     shall be limited to all or any part of the same  Property  that secured the
     Lien extended, renewed or replaced (plus improvements on such Property).

     Notwithstanding the foregoing restrictions, the Company may, and may permit
any Designated  Subsidiary to, incur Debt secured by Liens on Property which are
not otherwise excepted without equally and ratably securing the Notes,  provided

     fiduciary, settlor,  beneficiary,  member, shareholder of or possessor of a
     power over such Holder, if such Holder is an estate, a trust, a partnership

     presentation by the Holder of such Note or any payment appertaining thereto
     for  payment  on a date  more  than 15 days  after  the date on which  such
     payment became due and payable or the date on which payment thereof is duly
     provided for, whichever occurs later;

          (c) any estate, inheritance,  gift, sales, transfer, personal property
     or similar Tax;

          (d)  any  Tax  which  is  payable   otherwise  than  by  deduction  or
     withholding from payments of principal of, premium,  if any, or interest on
     such Note;

          (e) any Tax imposed on a Holder that is a partnership  or a fiduciary,
     but  only  to the  extent  that  any  beneficial  owner  or  member  of the
     partnership or  beneficiary or settlor with respect to the fiduciary  would
     not have been entitled to the payment of Other  Additional  Amounts had the
     beneficial  owner,  member,  beneficiary or settlor  directly  received its
     beneficial or distributive share of payments on such Note; or

          (f) any combination of items (a), (b), (c), (d) and (e).

were or would be payable in respect thereof  pursuant to such terms, and express
mention of the  payment  of Other  Additional  Amounts  (if  applicable)  in any
provision hereof shall not be construed as excluding Other Additional Amounts in
those provisions hereof where such express mention is not made.

     If any  failure,  default or  acceleration  referred to in clause (4) above
shall  cease or be  cured,  waived,  rescinded  or  annulled,  then the Event of
Default  hereunder  by  reason  thereof  shall be deemed  likewise  to have been
thereupon cured.


                                                                              30


     A Default  with  respect to Notes under  clauses (3) or (4) of this Section
6.1 is not an Event of  Default  until the  Trustee  (by  written  notice to the
Company) or the  Holders of at least 25% in  aggregate  principal  amount of the
outstanding  Notes (by  written  notice to the Company  and the  Trustee)  gives
notice of the Default and the Company does not cure such Default within the time
specified in said clause (3) or (4) after  receipt of such  notice.  Such notice
must specify the Default,  demand that it be remedied and state that such notice
is a "Notice of Default."

     The Company shall deliver to the Trustee, within 30 days after knowledge of
the occurrence thereof,  written notice in the form of an Officers'  Certificate
of any event  which with the giving of notice or the lapse of time would  become
an Event of Default under clause (3), (4) or (5) of this Section 6.1, its status
and what action the Company is taking or proposes to take with respect thereto.

     SECTION 6.2. Acceleration. If an Event of Default with respect to the Notes
(other  than an Event of  Default  specified  in Section  6.1(5) or 6.1(6)  with
respect to the Company)  occurs and is continuing,  the Trustee by notice to the
Company,  or the Holders of at least 25% in  aggregate  principal  amount of the
outstanding Notes by notice to the Company and the Trustee, may, and the Trustee
at the written request of such Holders,  subject to Section 6.5, shall,  declare
the principal of and accrued but unpaid  interest on all the Notes to be due and
payable. Upon such a declaration, such principal and accrued and unpaid interest
shall  be due and  payable  immediately.  If an Event of  Default  specified  in
Section  6.1(5) or 6.1(6) with respect to the Company  occurs and is continuing,
the  principal  of and accrued  and unpaid  interest on all the Notes shall ipso
facto become and be immediately due and payable without any declaration or other
act on the part of the  Trustee or any  Holders.  The  Holders of a majority  in
aggregate principal amount of the outstanding Notes by notice to the Trustee may
rescind an acceleration  and its  consequences if all existing Events of Default
have been cured or waived  except  nonpayment  of principal or interest that has
become due solely because of such acceleration and the Trustee has been paid any
amounts  due to it for  reasonable  compensation,  expenses,  disbursements  and
advances of the  Trustee,  its agents and counsel and any other  amounts due the
Trustee under Section 7.7 hereof. No such rescission shall affect any subsequent
Default or Event of Default or impair any right consequent thereto.

     SECTION 6.3. ....Other Remedies. If an Event of Default with respect to the
Notes occurs and is continuing,  the Trustee may pursue any available  remedy to
collect the payment of  principal  of or interest on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

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

     SECTION 6.4. Waiver of Past Defaults.  Subject to the payment of any amount
due to the Trustee  under  Section  6.2,  the Holders of a majority in aggregate
principal  amount of 



                                                                              31

the Notes then outstanding by notice to the Trustee may, on behalf o the Holders
of the Notes,  waive any past or  existing  Default or Event of Default  and its
consequences except (i) an uncured Default or Event of Default in the payment of
the  principal  of or interest on a Note or (ii) an uncured  Default or Event of
Default in  respect of a  provision  that  under  Section  9.2 cannot be amended
without  the  consent of each  Noteholder  affected.  When a Default or Event of
Default  is  waived,  it is  deemed  cured,  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 consequent right.

     SECTION 6.5.  Control by Majority.  Upon provision of security or indemnity
satisfactory  to the Trustee,  the Holders of a majority in aggregate  principal
amount of the Notes then  outstanding  may direct the time,  method and place of
conducting any  proceeding for any remedy  available to the Trustee with respect
to the Notes or of  exercising  any  trust or power  conferred  on the  Trustee.
However,  the Trustee,  which may conclusively rely on opinions of counsel,  may
refuse to follow any direction that conflicts with law or this Indenture or that
the Trustee  determines is unduly prejudicial to the rights of other Noteholders
or would involve the Trustee in personal liability;  provided, however, that the
Trustee  may take any other  action  deemed  proper by the  Trustee  that is not
inconsistent with such direction.

     SECTION  6.6.  Limitation  on Suits.  A Holder of Notes may not  pursue any
remedy with respect to this Indenture or the Notes unless:

               (i) An Event of Default shall have occurred and be continuing and
          the Holder gives to the Trustee prior written  notice  stating that an
          Event of Default is continuing;

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

               (iii)  such  Holder or  Holders  offer to the  Trustee  indemnity
          satisfactory  to it against  any costs,  liabilities  or  expenses  in
          compliance with such request;

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

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

     A Noteholder  may not use this Indenture to prejudice the rights of another
Noteholder  or to obtain a preference or priority  over another  Noteholder  (it
being  understood  that  the  Trustee  shall  not  have an  affirmative  duty to
ascertain whether or not such actions or forbearances are unduly  prejudicial to
such Noteholders).

     SECTION  6.7.  Rights of Holders To Receive  Payment.  Notwithstanding  any
other provision of this Indenture, the right of any Holder to receive payment of
principal  of and  interest  on the Notes held by such  Holder,  on or after the
respective  due  dates  expressed  in  the  

                                                                              32


Notes, or to bring suit for the enforcement of any such payment on or after such
respective dates,  shall not be impaired or affected without the consent of such
Holder.

     SECTION 6.8.  Collection Suit by Trustee.  If an Event of Default specified
in Section  6.1(1) or 6.1(2) occurs and is  continuing,  the Trustee may recover
judgment in its own name and as trustee of an express  trust against the Company
for the whole amount then due and owing  (together  with  interest on any unpaid
interest to the extent lawful) and the amounts provided for in Section 7.7.

     SECTION  6.9.  Trustee May File Proofs of Claim.  The Trustee may file such
proofs of claim and other  papers or  documents as may be necessary or advisable
in order  to have  the  claims  of the  Trustee  (including  any  claim  for the
reasonable  compensation,  expenses,  disbursements and advances of the Trustee,
its agents and counsel) and the Noteholders allowed in any judicial  proceedings
relative to the Company or the property of the Company under any Bankruptcy Law,
and, unless prohibited by law or applicable  regulations,  may vote on behalf of
the  Holders  in any  election  of a  trustee  in  bankruptcy  or  other  Person
performing similar functions.  Any Custodian in any such judicial  proceeding is
hereby  authorized  by each Holder to make  payments to the Trustee  and, in the
event that the Trustee shall consent to the making of such payments  directly to
the  Holders,  to  pay to the  Trustee  any  amount  due it for  the  reasonable
compensation,  expenses,  disbursements and advances of the Trustee,  its agents
and its  counsel,  and any other  amounts due the Trustee  under  Section 7.7 in
accordance with Section 6.10.

     SECTION  6.10.  Priorities.  Any money or other  property  collected by the
Trustee pursuant to Article VI hereof, or any money or other property  otherwise
distributable  in respect of the  Company's  obligations  under this  Indenture,
shall be applied in the following order:

               FIRST:  to the Trustee  (including any  predecessor  Trustee) for
               amounts due under Section 7.7;

               SECOND:  to  Noteholders  for amounts due and unpaid on the Notes
          for principal and interest, ratably, without preference or priority of
          any kind,  according  to the  amounts due and payable on the Notes for
          principal and interest, respectively; and

               THIRD: to the Company.

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

     SECTION 6.11. Undertaking for Costs. In any suit for the enforcement of any
right or remedy under this  Indenture or in any suit against the Trustee for any
action taken or omitted by it as Trustee,  a court in its discretion may require
the filing by any party  litigant in the suit of an undertaking to pay the costs
of the suit,  and the  court in its  discretion  may  assess  reasonable  costs,
including reasonable attorneys' fees and expenses, 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




                                                                              33


pursuant  to  Section  6.7 or a suit by  Holders  of more than 10% in  aggregate
principal amount of the outstanding Notes.

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

                                  ARTICLE VII

                                     Trustee

     SECTION 7.1. Duties of Trustee. (a) If an Event of Default has occurred and
is continuing,  the Trustee shall exercise the rights and powers vested in it by
this  Indenture and use the same degree of care and skill in their exercise as a
prudent Person would exercise or use under the  circumstances  in the conduct of
such Person's own affairs.

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

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

          (ii)  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 Officers' Certificates and Opinions of
     Counsel furnished to the Trustee and conforming to the requirements of this
     Indenture.  However,  in the case of any such  Officers'  Certificates  and
     Opinions of Counsel which by any provision hereof are specifically required
     to be furnished to the Trustee,  the Trustee shall  examine such  Officers'
     Certificates  and  Opinions  of  Counsel to  determine  whether or not they
     conform to the requirements of this Indenture.

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

          (i) this  subsection  does not limit the effect of  Section  7.1(b) or
     Section 7.1(f);

          (ii) 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

                                                                              34

          (iii) 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.

     (d)  Every  provision  of this  Indenture  that in any way  relates  to the
Trustee is subject to Section 7.1(a), 7.1(b), 7.1(c) and 7.1(f).

     (e) The  Trustee  shall not be liable  for  interest  on any money or other
property received by it or for holding moneys or other property  uninvested,  in
either  case,  except as otherwise  agreed  between the Company and the Trustee.
Money and other  property  held in trust by the  Trustee  shall,  until  used or
applied as herein  provided,  be held in trust for the  purposes  for which they
were received, but need not be segregated from other money or property except to
the extent required by law.

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

     (g) Every provision of this Indenture  relating to the conduct or affecting
the liability of or affording  protection to the Trustee shall be subject to the
provisions of this Section 7.1 and to the provisions of the Trust Indenture Act,
where applicable.

     SECTION 7.2. Rights of Trustee.  (a) The Trustee may conclusively  rely on,
and shall be protected in acting or  refraining  from acting in reliance on, any
document  believed by it to be genuine and to have been signed or  presented  by
the proper person. The Trustee need not investigate any fact or matter stated in
the document.

     (b) Before the Trustee  acts or  refrains  from  acting,  it may require an
Officers'  Certificate or an Opinion of Counsel,  or both. The Trustee shall not
be liable for any action it takes or omits to take in good faith in  reliance on
the Officers' Certificate or Opinion of Counsel.

     (c) The  Trustee  may  execute  any of the trusts or powers or perform  any
duties hereunder either directly through attorneys and agents, respectively, and
shall not be  responsible  for the  misconduct  or negligence of any attorney or
agent appointed with due care by it hereunder.

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

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

                                                                              35

     (f) The Trustee  shall be under no obligation to exercise any of the rights
or powers  vested in it by this  Indenture at the request or direction of any of
the Holders  pursuant to this Indenture,  unless such Holders shall have offered
to the  Trustee  security  or  indemnity  satisfactory  to it against the costs,
expenses and  liabilities  which might be incurred by it in compliance with such
request or direction.

     (g) The Trustee shall not be charged with knowledge of any Default or Event
of Default  with respect to the Notes unless  either (1) a Trust  Officer  shall
have actual  knowledge of such Default or Event of Default or (2) written notice
of such Default or Event of Default  shall have been given to a Trust Officer of
the Trustee at the Corporate Trust Office by the Company or any other obligor on
the Notes or by any Holder of the Notes.  Any such notice shall  reference  this
Indenture and the Notes.

     (h) The rights, privileges,  protections,  immunities and benefits given to
the Trustee pursuant to this Indenture,  including its rights to be indemnified,
are  extended  to,  and shall be  enforceable  by,  the  Trustee  in each of its
capacities as Registrar and Paying Agent, as the case may be, hereunder.

     (i) The Trustee shall not be bound to make any investigation into the facts
or  matters  stated  in  any  resolution,  certificate,  statement,  instrument,
opinion,  report, notice, request,  direction,  consent, order, bond, debenture,
note,  other  evidence  of  indebtedness  or other  paper or  document,  but the
Trustee,  in its  discretion,  may  make  such  further  reasonable  inquiry  or
reasonable  investigation  into such facts or matters as it may see fit, and, if
the Trustee shall  determine to make such further inquiry or  investigation,  it
shall be entitled,  upon reasonable  notice and at reasonable  times, to examine
the books,  records  and  premises  of the  Company,  personally  or by agent or
attorney  at the sole  cost of the  Company  and  shall  incur no  liability  or
additional liability of any kind by reason of such inquiry or investigation.

     (j) The  Trustee  may  request  that the  Company  deliver  a  certificate,
substantially  in the form of  Exhibit  E  hereto,  setting  forth  the names of
individuals and/or titles of Officers  authorized at such time to take specified
actions pursuant to this Indenture.

     (k) The  permissive  rights of the Trustee  enumerated  herein shall not be
construed as duties.

     SECTION 7.3. Individual Rights of Trustee. The Trustee in its individual or
any other  capacity  may become the owner or pledgee of Notes and may  otherwise
deal with the Company with the same rights it would have if it were not Trustee.
Any Paying Agent, Registrar or co-paying agent may do the same with like rights.
However, the Trustee must comply with Sections 7.10 and 7.11.

     SECTION 7.4. Trustee's Disclaimer. The Trustee shall not be responsible for
and makes no  representation as to the validity or adequacy of this Indenture or
the Notes,  it shall not be  accountable  for the  Company's use of the proceeds
from the Notes, and it shall not be responsible for any statement of the Company
in this Indenture or in any document  issued in connection  with the sale of the
Notes or in the Notes other than the Trustee's certificate of authentication.

                                                                              36


     SECTION 7.5. Notice of Defaults. If a Default or an Event of Default occurs
with respect to the Notes and is continuing  and if it is actually  known to the
Trustee,  the Trustee shall mail to each Noteholder notice of the Default within
90 days after it is known to a Trust Officer or written notice of it is received
by a Trust Officer of the Trustee. Except in the case of a Default in payment of
principal of or interest on any Note, the Trustee may withhold the notice if and
so long as a  committee  of its Trust  Officers  in good faith  determines  that
withholding the notice is not opposed to the interests of Noteholders.

     SECTION 7.6.Reports by Trustee to Holders. As promptly as practicable after
each May 15 beginning with the May 15 following the date of this Indenture,  and
in any event  prior to July 15 in each  year,  the  Trustee  shall  mail to each
Noteholder  a brief report  dated as of such May 15 that  complies  with Section
313(a) of the Trust  Indenture  Act.  The Trustee also shall comply with Section
313(b) of the Trust  Indenture  Act. The Trustee shall  promptly  deliver to the
Company a copy of any report it  delivers to Holders  pursuant  to this  Section
7.6.

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

     SECTION 7.7.  Compensation and Indemnity.  The Company covenants and agrees
to pay to the  Trustee  (and any  predecessor  Trustee)  from  time to time such
reasonable  compensation  for its services as the Company and the Trustee  shall
from time to time agree in  writing.  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  out-of-pocket
expenses  (including  attorneys' fees and expenses),  disbursements and advances
incurred or made by it in  accordance  with the  provisions  of this  Indenture,
including  costs  of  collection,  in  addition  to  such  compensation  for its
services, except any such expense, disbursement or advance as may arise from its
negligence,  willful  misconduct or bad faith.  Such expenses  shall include the
reasonable  compensation  and  expenses,   disbursements  and  advances  of  the
Trustee's agents and counsel.  The Trustee shall provide the Company  reasonable
notice of any expenditure  not in the ordinary  course of business.  The Company
shall indemnify each of the Trustee, its officers, directors,  employees and any
predecessor  Trustees  against any and all loss,  damage,  claim,  liability  or
expense  (including  reasonable  attorneys' fees and expenses) (other than taxes
applicable to the Trustee's compensation hereunder) incurred by it in connection
with the acceptance or  administration  of this trust and the performance of its
duties hereunder. The Trustee shall notify the Company promptly of any claim for
which it may seek  indemnity.  Failure by the  Trustee so to notify the  Company
shall not relieve the Company of its obligations hereunder, except to the extent
that the Company has been  prejudiced by such failure.  The Company shall defend
the claim and the Trustee  shall  cooperate,  to the extent  reasonable,  in the
defense of any such claim,  and,  if (in the opinion of counsel to the  Trustee)
the facts and/or issues  surrounding the claim are reasonably likely to create a
conflict  with the  Company,  the  Company  shall  pay the  reasonable  fees and
expenses of separate counsel to the Trustee.  The Company need not reimburse any
expense or  indemnify  against any loss,  liability  or expense  incurred by the
Trustee through the Trustee's own willful  misconduct,  negligence or bad faith.
The Company need not pay for any  settlement  made  without its  consent,  which
consent shall not be unreasonably withheld or delayed.

                                                                              37

     To secure the  Company's  payment  obligations  in this  Section  7.7,  the
Trustee (including any predecessor trustee) shall have a lien prior to the Notes
on all money or property  held or collected  by the Trustee  other than money or
property held in trust to pay principal of and premium,  if any, and interest on
particular Notes.

     The  Company's  payment  obligations  pursuant  to this  Section  7.7 shall
survive the  satisfaction,  discharge and  termination  of this  Indenture,  the
resignation  or removal  of the  Trustee  and any  discharge  of this  Indenture
including any  discharge  under any  Bankruptcy  Law. In addition to and without
prejudice to the rights  provided to the Trustee under any of the  provisions of
this Indenture,  when the Trustee incurs expenses or renders  services after the
occurrence  of a Default  specified in Section  6.1(5) or 6.1(6) with respect to
the Company,  the expenses and the compensation for the services are intended to
constitute expenses of administration under the Bankruptcy Law.

     SECTION  7.8.  Replacement  of Trustee.  The Trustee may resign at any time
upon 30 days'  written  notice to the  Company.  The  Holders of a  majority  in
principal amount of the Notes then  outstanding,  may remove the Trustee upon 30
days' written notice to the Trustee and may appoint a successor  Trustee,  which
successor  Trustee  shall be reasonably  acceptable to the Company.  The Company
shall remove the Trustee if:

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

          (ii) the Trustee is adjudged bankrupt or insolvent;

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

          (iv) the Trustee otherwise becomes incapable of acting.

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

     A successor  Trustee shall deliver a written  acceptance of its appointment
to the retiring Trustee and to the Company and the Company shall pay all amounts
due and owing to the Trustee under Section 7.7 of the  Indenture.  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 Noteholders  affected by such resignation or removal. 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 7.7.

     If a  successor  Trustee  does not take  office  with  respect to the Notes
within 30 days after the retiring  Trustee  resigns or is removed,  the retiring
Trustee or the Holders of 10% in principal  amount of the Notes may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

                                                                              38

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

     Notwithstanding  the  replacement  of the Trustee  pursuant to this Section
7.8, the Company's  obligations under Section 7.7 shall continue for the benefit
of the retiring Trustee.

     SECTION 7.9. Successor Trustee by Merger. If the Trustee consolidates with,
merges or converts  into,  or transfers all or  substantially  all its corporate
trust business or assets to, another  corporation  or banking  association,  the
resulting,  surviving or transferee corporation without any further act shall be
the  successor  Trustee;  provided  that  such  corporation  shall be  otherwise
qualified  and eligible  under this Article VII and Section  310(a) of the Trust
Indenture  Act,  without the execution or filing of any paper or any further act
on the part of the parties hereto.

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

     SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all times
satisfy the  requirements  of Section  310(a) of the Trust  Indenture  Act.  The
Trustee shall have a combined capital and surplus of at least $50,000,000 as set
forth in its most recent published annual report of condition. The Trustee shall
comply with Section 310(b) of the Trust Indenture Act; provided,  however,  that
there shall be excluded  from the  operation  of Section  310(b)(1) of the Trust
Indenture  Act any  indenture  or  indentures  under which other  securities  or
certificates of interest or participation in other securities of the Company are
outstanding  if the  requirements  for  such  exclusion  set  forth  in  Section
310(b)(1) of the Trust Indenture Act are met.

     Nothing  herein shall  prevent the Trustee from filing with the  Commission
the application referred to in the second to last paragraph of Section 310(b) of
the Trust Indenture Act.

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

                                                                              39

                                  ARTICLE VIII

                       Discharge of Indenture; Defeasance

     SECTION 8.1. Discharge of Liability on Notes;  Defeasance.  With respect to
the Notes,  (a) when (i) the Company  delivers  to the  Trustee all  outstanding
Notes that have not already been  delivered to the Trustee for  cancellation  or
(ii) all outstanding  Notes have become due and payable,  whether at maturity or
as a result of the  mailing of a notice of  redemption  pursuant  to Article III
hereof or the Notes shall become due and payable at their Stated Maturity within
one year,  or the Notes are to be called  for  redemption  within one year under
arrangements  satisfactory to the Trustee for the giving of notice of redemption
by the Trustee in the name,  and at the expense,  of the  Company,  and, in each
case of this  clause  (ii),  the  Company  irrevocably  deposits or causes to be
deposited  with  the  Trustee  funds  sufficient  to pay  at  maturity  or  upon
redemption all outstanding Notes, including interest thereon to maturity or such
redemption  date,  and if in either case the Company pays all other sums payable
hereunder by the Company,  then this Indenture shall, subject to Section 8.1(c),
cease to be of further effect.  The Trustee shall  acknowledge  satisfaction and
discharge of this Indenture on demand of the Company accompanied by an Officers'
Certificate from the Company and an Opinion of Counsel from the Company that all
conditions  precedent provided herein for relating to satisfaction and discharge
of this  Indenture  have been  complied  with and at the cost and expense of the
Company.

     (b)  Subject  to  Sections  8.1(c)  and 8.2,  the  Company  at any time may
terminate (i) all of its obligations  under the Notes and this Indenture ("legal
defeasance  option") or (ii) its  obligations  under Section 4.2 and Section 4.3
and the operation of Sections 6.1(3) and 6.1(4) ("covenant  defeasance option").
The Company may exercise its legal defeasance option  notwithstanding  its prior
exercise of its covenant defeasance option.

     If the Company  exercises its legal  defeasance  option with respect to the
Notes,  payment  of the  Notes  may not be  accelerated  because  of an Event of
Default. If the Company exercises its covenant defeasance option, payment of the
Notes  may not be  accelerated  because  of an Event  of  Default  specified  in
Sections  6.1(3)  (only with  respect to the  covenants  terminated  pursuant to
Section 8.1(b)(ii) above) or 6.1(4).

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

     (c) Notwithstanding clauses (a) and (b) above, the Company's obligations in
Sections  2.3, 2.4, 2.5, 2.9, 4.1, 4.5, 7.7, 7.8, 8.4, 8.5 and 8.6 shall survive
until  the  Notes  have been paid in full.  Thereafter,  the  Company's  and the
Trustee's obligations in Sections 7.7, 8.4 and 8.5 shall survive.

     SECTION 8.2.  Conditions to Defeasance.  The Company may exercise its legal
defeasance  option or its covenant  defeasance  option with respect to the Notes
only if:

          (i) the  Company  irrevocably  deposits or causes to be  deposited  in
     trust with the Trustee money or U.S.  Government  Obligations which through
     the  scheduled  

                                                                              40


     payment of principal  and interest in respect  thereof in  accordance  with
     their terms shall  provide  cash at such times and in such amounts as shall
     be sufficient  to pay  principal  and interest when due on all  outstanding
     Notes  (except  Notes  replaced  pursuant  to Section  2.9) to  maturity or
     redemption, as the case may be;

          (ii)  the  Company  delivers  to  the  Trustee  a  certificate  from a
     nationally  recognized  firm of independent  accountants  expressing  their
     opinion that the payments of  principal  and interest  when due and without
     reinvestment  on  the  deposited  U.S.  Government   Obligations  plus  any
     deposited money without  investment shall provide cash at such times and in
     such amounts as shall be  sufficient to pay principal and interest when due
     on all outstanding Notes (except Notes replaced pursuant to Section 2.9) to
     maturity or redemption, as the case may be;

          (iii) 91 days pass  after the  deposit  is made and  during the 91-day
     period no Default  with  respect  to the  Company  as debtor  specified  in
     Section  6.1(5)  or 6.1(6)  occurs  which is  continuing  at the end of the
     period;

          (iv) the  deposit  does not  constitute  a  default  under  any  other
     material agreement binding on the Company;

          (v) in the case of the legal defeasance option, the Company shall have
     delivered to the Trustee an Opinion of Counsel stating that (i) the Company
     has received  from, or there has been  published  by, the Internal  Revenue
     Service a ruling, or (ii) since the date of this Indenture there has been a
     change in the  applicable  federal  income tax law,  in either  case to the
     effect that,  and based thereon such Opinion of Counsel shall confirm that,
     the Noteholders shall not recognize income, gain or loss for federal income
     tax  purposes  as a result  of such  deposit  and  defeasance  and shall be
     subject to federal  income tax on the same amounts,  in the same manner and
     at the  same  times  as  would  have  been  the  case if such  deposit  and
     defeasance had not occurred;

          (vi) in the case of the covenant  defeasance option, the Company shall
     have  delivered to the Trustee an Opinion of Counsel to the effect that the
     Noteholders shall not recognize income, gain or loss for federal income tax
     purposes as a result of such deposit and defeasance and shall be subject to
     federal income tax on the same amounts,  in the same manner and at the same
     times as would have been the case if such  deposit and  defeasance  had not
     occurred; and

          (vii) the Company delivers to the Trustee an Officers' Certificate and
     an Opinion of Counsel,  each stating that all  conditions  precedent to the
     defeasance and discharge of the Notes as  contemplated by this Article VIII
     have been complied with.

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

     SECTION 8.3.  Application  of Trust Money.  The Trustee shall hold in trust
money or U.S. Government  Obligations deposited with it pursuant to this Article
VIII.  It shall  apply the  deposited  money and the money from U.S.  Government
Obligations  either  directly  or 

                                                                              41


through the Paying Agent as the Trustee may  determine  and in  accordance  with
this Indenture to the payment of principal of and interest on the Notes.

     SECTION 8.4.  Repayment  to the  Company.  The Trustee and the Paying Agent
shall  promptly  turn over to the  Company  upon  request  any  excess  money or
securities held by them at any time.

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

     Any unclaimed funds held by the Trustee  pursuant to this Section 8.4 shall
be held uninvested and without any liability for interest.

     SECTION 8.5.  Indemnity for Government  Obligations.  The Company shall pay
and shall  indemnify the Trustee against any tax, fee or other charge imposed on
or assessed against deposited U.S.  Government  Obligations or the principal and
interest received on such U.S.  Government  Obligations other than any such tax,
fee or  other  charge  which by law is for the  account  of the  Holders  of the
defeased  Notes;  provided that the Trustee shall be entitled to charge any such
tax, fee or other charge to such Holder's account.

     SECTION  8.6.  Reinstatement.  If the Trustee or Paying  Agent is unable to
apply any money or U.S.  Government  Obligations in accordance with this Article
VIII 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 Notes shall be revived  and  reinstated  as though no deposit  had  occurred
pursuant to this  Article VIII until such time as the Trustee or Paying Agent is
permitted to apply all such money or U.S.  Government  Obligations in accordance
with this Article VIII; provided,  however, that (a) if the Company has made any
payment of interest on or principal of any Notes following the  reinstatement of
its obligations, the Company shall be subrogated to the rights of the Holders of
such Notes to receive such payment from the money or U.S. Government Obligations
held by the  Trustee or Paying  Agent and (b) unless  otherwise  required by any
legal  proceeding  or any  order  or  judgment  of  any  court  or  governmental
authority,  the  Trustee or Paying  Agent  shall  return all such money and U.S.
Government Obligations to the Company promptly after receiving a written request
therefor at any time, if such  reinstatement  of the Company's  obligations  has
occurred and continues to be in effect.

                                   ARTICLE IX

                                   Amendments

     SECTION 9.1.  Without  Consent of Holders.  The Company and the Trustee may
amend  this  Indenture  or  the  Notes  without  notice  to or  consent  of  any
Noteholder:

                                                                              42


          (i) to cure any ambiguity, omission, defect or inconsistency;

          (ii) to comply with Article V;

          (iii) to add any additional Events of Default;

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

          (v) to add one or more  guarantees  for the  benefit of holders of the
     Notes;

          (vi) to secure the Notes pursuant to the terms of this Indenture;

     have terms substantially  identical in all material respects to the Initial
     Notes (except that the transfer restrictions contained in the Initial Notes
     shall be  modified or  eliminated,  as  appropriate,  and there shall be no
     registration  rights),  and  which  shall  be  treated,  together  with any
     outstanding Initial Notes, as a single issue of securities;

          (ix) to provide for the issuance of any Additional Notes;

          (x) to comply with any requirements in connection with qualifying this
     Indenture under the Trust Indenture Act;

          (xi) to comply with the rules of any applicable securities depository;

          (xii) to provide for  uncertificated  Notes in addition to or in place
     of certificated Notes; provided, however, that the uncertificated Notes are

     a manner such that the  uncertificated  Notes are as  described  in Section
     163(f)(2)(B) of the Code; and

          (xiii) to change any other  provision if the change does not adversely
     affect the interests of any Noteholder in any material respect.

     After an amendment  under this Section 9.1 becomes  effective,  the Company
shall mail to  Noteholders  a notice  briefly  describing  such  amendment.  The
failure to give such notice to all Noteholders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section 9.1.

     SECTION 9.2. With Consent of Holders. The Company and the Trustee may amend
this  Indenture  or the  Notes  without  notice to any  Noteholder  but with the
written consent of the Holders of at least a majority in principal amount of the
Notes then outstanding  (including consents obtained in connection with a tender
offer or exchange for Notes).  However,  without the consent of each  Noteholder
affected, an amendment may not:

                                                                              43


          (i) change the Stated  Maturity of the principal of, or installment of
     interest on, any Note;

     change the date on which any Note must be redeemed;

          (iv) change the coin or currency in which the principal of or interest
     on any Note is payable;

          (v)  impair  the  right  of any  Holder  to  institute  suit  for  the
     enforcement of any payment on or after the Stated Maturity of any Note;

          (vi) reduce the  percentage  in  principal  amount of the  outstanding
     Notes,  the consent of whose  Holders is required in order to take  certain
     actions;

          (vii) modify any of the  provisions  of this  Indenture  regarding the
     waiver of past  defaults  and the  waiver of certain  covenants  by Holders
     except to increase any percentage  vote required or to provide that certain
     other  provisions of the Indenture cannot be modified or waived without the
     consent of the holder of each Note affected thereby; or

          (viii) modify any of the above provisions of this Section 9.2.

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

     After an amendment  under this Section 9.2 becomes  effective,  the Company
shall mail to  Noteholders  a notice  briefly  describing  such  amendment.  The
failure to give such notice to all Noteholders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section 9.2.

     SECTION 9.3.  Compliance  with Trust Indenture Act. Every amendment to this
Indenture  or the Notes  shall  comply with the Trust  Indenture  Act as then in
effect.

     SECTION 9.4.  Effect of Consents and  Waivers.  A consent to an  amendment,
supplement  or a waiver by a Holder of a Note  shall  bind the  Holder and every
subsequent  Holder of that Note or portion of the Note that  evidences  the same
debt as the consenting  Holder's Note, even if notation of the consent or waiver
is not made on the Note.  After an amendment or waiver  becomes  effective  with
respect to the Notes, it shall bind every Noteholder.

     The Company may,  but shall not be obligated  to, fix a record date for the
purpose of determining  the  Noteholders  entitled to give their consent or take
any other action  described  above or required or permitted to be taken pursuant
to  this  Indenture.  If a  record  date  is  fixed,  then  notwithstanding  the
immediately  preceding  paragraph,  those Persons who were  Noteholders  at such
record date (or their duly designated proxies), and only those Persons, shall be
entitled to 

                                                                              44


give  such  consent  or to take any such  action,  whether  or not such  Persons
continue to be Holders after such record date.

     SECTION 9.5.  Notation on or Exchange of Notes. If an amendment changes the
terms of a Note, the Trustee may require the Holder of the Note to deliver it to
the Trustee.  The Company shall provide in writing to the Trustee an appropriate
notation to be placed on the Note  regarding  the changed terms and return it to
the  Holder.  Alternatively,  if the Company or the  Trustee so  determine,  the
Company in exchange for the Note shall issue and the Trustee shall  authenticate
a new Note that  reflects  the changed  terms.  Failure to make the  appropriate
notation or to issue a new Note shall not affect the validity of such amendment.

     SECTION  9.6.Trustee  To  Sign  Amendments.  The  Trustee  shall  sign  any
amendment  authorized  pursuant  to this  Article IX if the  amendment  does not
adversely affect the rights,  duties,  liabilities or immunities of the Trustee.
If it does,  the Trustee may but need not sign it. In signing such amendment the
Trustee shall receive indemnity reasonably satisfactory to it and be entitled to
receive,  and (subject to Section 7.1) shall be fully  protected in conclusively
relying  upon,  in  addition  to the  documents  required  by Section  10.4,  an
Officers' Certificate of the Company and an Opinion of Counsel stating that such
amendment  complies  with  the  provisions  of this  Article  IX and  that  such
supplemental indenture constitutes the legal valid and binding obligation of the
Company in accordance with its terms subject to customary exceptions.

     Upon the  execution of any  supplemental  indenture  under this Article IX,
this Indenture shall be modified in accordance therewith,  and such supplemental
Indenture  shall  form a part of this  Indenture  for all  purposes;  and  every
Noteholder theretofore or thereafter authenticated and delivered hereunder shall
be bound thereby.

except  that,  for the  purpose of  determining  whether  the  Trustee  shall be
protected in conclusively relying on any such direction, waiver or consent, only
Notes which a Trust Officer of the Trustee  actually knows are so owned shall be
so disregarded.  Also,  subject to the foregoing,  only Notes outstanding at the

                            5% Senior Notes due 2015

1.   Interest

     THERMO  ELECTRON  CORPORATION,  a Delaware  corporation  (together with its
successors and assigns under the Indenture hereinafter referred to, being herein
called the "Company"),  promises to pay interest on the principal amount of this
Note at the rate of 5% per annum;  provided,  however, that, upon the occurrence
or failure to occur of  certain  events  specified  in the  Registration  Rights
Agreement,  the Company shall,  subject to the terms and conditions set forth in
the  Registration  Rights  Agreement,  pay additional  interest on the principal
amount of this Note at a rate of 0.25% per annum for the first 90-day period (or
portion thereof) after such event occurs or fails to occur,  which rate shall be
increased by 0.25% per annum at the  beginning of the  subsequent  90-day period
and continue  thereafter so long as such event  continues or fails to occur,  as
the case may be;  provided  that the maximum  aggregate  increase in the rate of
interest in respect of this Note shall in no event exceed 0.50% per annum.  Such
additional  interest shall be payable in addition to any other interest  payable
from time to time with respect to this Note.

     The Company  shall pay  interest  semiannually  on June 1 and December 1 of
each year (each such date, an "Interest Payment Date"),  commencing on [December
1, 2005]  [first  interest  payment  date  relating  to any  Additional  Notes].
Interest on the Notes shall  accrue from [May 27, 2005] [date of issuance of any
Additional  Notes], or from the most recent date to which interest has been paid
on the  Notes.  Interest  shall  be  computed  on the  basis of a  360-day  year
comprised of twelve 30-day months.

2.   Method of Payment

     By no later than  10:00 a.m.  (New York City time) on the date on which any
principal  of or interest  on any Note is due and  payable,  the  Company  shall
irrevocably deposit with the Trustee or the Paying Agent money sufficient to pay
such principal and/or interest. The Company shall pay interest (except defaulted
interest)  to the  Persons who are  registered  Holders of Notes at the close of
business on the May 15 or November 15 next  preceding the interest  payment date
even if Notes are  cancelled,  repurchased or redeemed after the record date and
on or before the interest payment date. Holders must surrender Notes to a Paying
Agent to  collect  principal  payments.  The  Company  shall pay  principal  and
interest  in money of the  United  States  that at the time of  payment is legal
tender for  payment of public and  private  debts.  Payments in respect of Notes
represented  by a  Global  Note  (including  principal,  premium,  if  any,  and
interest)  shall be made by the transfer of immediately  available  funds to the
accounts  specified by The Depository  Trust  Company.  The Company may make all
payments in respect of a Definitive Note (including principal,  premium, if any,
and  interest)  by  mailing a check to the  registered  address  of each  Holder
thereof  or by  wire  transfer  to an  account  located  in  the  United  States
maintained by the payee.

                                      A-3


3.   Paying Agent and Registrar

     JPMorgan Chase Bank, N.A., a national banking  association (the "Trustee"),
shall  initially act as Paying Agent and Registrar.  The Company may appoint and
change any Paying  Agent or  Registrar  without  notice to any  Noteholder.  The
Company or any of its domestically  organized wholly owned  Subsidiaries may act
as Paying Agent.

4.   Indenture

     The Company  issued the Notes under an  Indenture  dated as of May 27, 2005
(as it may be amended or  supplemented  from time to time in accordance with the
terms thereof, the "Indenture"),  between the Company and the Trustee. The terms
of the Notes  include  those stated in the  Indenture and those made part of the
Indenture  by  reference to the Trust  Indenture  Act of 1939 (15 U.S.C.  ss.ss.
77aaa-77bbbb)  as in effect on the date of the Indenture  (the "Trust  Indenture
Act").  Capitalized  terms used herein and not defined  herein have the meanings
ascribed thereto in the Indenture.  The Notes are subject to all such terms, and
Noteholders  are referred to the  Indenture  and the Trust  Indenture  Act for a
statement of those  terms.  To the extent any  provision of this Note  conflicts
with the express  provisions of the  Indenture,  the provisions of the Indenture
shall govern and be controlling.

     The Notes are senior unsecured  obligations of the Company. The Note is one
of the Initial Notes referred to in the Indenture. The Notes include the Initial
Notes issued on the Issue Date, any Additional  Notes issued in accordance  with
Section 2.15 of the Indenture and the Exchange  Notes issued in exchange for the
Initial Notes or Additional Notes pursuant to the Indenture.  The Initial Notes,
any  Additional  Notes and the  Exchange  Notes are treated as a single class of
securities under the Indenture. The Indenture imposes certain limitations on the
ability of the Company and its Subsidiaries to create liens, enter into sale and
lease-back transactions and enter into mergers and consolidations.

5.   Optional Redemption

     The Notes shall be  redeemable,  in whole or in part,  at any time and from
time to time, at the option of the Company,  at a redemption  price equal to the
greater  of (i) 100% of the  principal  amount of such Notes and (ii) the sum of
the present values of the remaining scheduled payments of principal and interest
thereon (exclusive of interest accrued to the date of redemption)  discounted to
the redemption date on a semiannual  basis (assuming a 360-day year comprised of
twelve 30-day months) at the Treasury Rate plus 15 basis points (the "Make-Whole
Amount"), plus accrued interest thereon to the redemption date.

     "Comparable  Treasury Issue" means the United States  Treasury  security or
securities  selected by an  Independent  Investment  Banker as having a maturity
comparable  to the  remaining  term of the Notes to be  redeemed  that  would be
utilized,  at the time of selection and in accordance  with customary  financial
practice,  in pricing new issues of corporate  debt  securities  of a comparable
maturity to the remaining term of the Notes to be redeemed.

     "Comparable  Treasury Price" means, with respect to any redemption date for
the Notes, (a) the average of the Reference  Treasury Dealer Quotations for such
redemption  date,  after  excluding  the  highest  and lowest of such  Reference
Treasury Dealer Quotations or (b) if the

                                      A-4



Company obtains fewer than four such Reference Treasury Dealer  Quotations,  the
average of all such Reference Treasury Dealer Quotations.

     "Independent Investment Banker" means one of the Reference Treasury Dealers
appointed by the Company.

     "Reference  Treasury  Dealer" means each of Barclays  Capital Inc. and J.P.
Morgan  Securities Inc. or their respective  affiliates which are primary United
States government securities dealers, and their respective  successors,  and two
other  firms which are  primary  U.S.  government  securities  dealers  that the
Company selects; provided,  however, that if any of the foregoing shall cease to
be a primary  U.S.  government  securities  dealer in The City of New York,  the
Company  shall  substitute   therefor  another  such  primary  U.S.   government
securities dealer.

     "Reference Treasury Dealer Quotation" means, with respect to each Reference
Treasury  Dealer and any  redemption  date,  the average,  as  determined by the
Company,  of the  bid  and  asked  prices  for  the  Comparable  Treasury  Issue
(expressed  in each case as a  percentage  of its  principal  amount)  quoted in
writing to the Company by such  Reference  Treasury  Dealer as of 3:30 p.m., New
York time, on the third Business Day preceding such redemption date.

     "Treasury  Rate" means,  with respect to any redemption date for the Notes,
the rate per annum  equal to the  semiannual  equivalent  yield to  maturity  or
interpolated (on a day-count basis) of the Comparable Treasury Issue, assuming a
price for the  Comparable  Treasury  Issue  (expressed  as a  percentage  of its
principal  amount) equal to the Comparable  Treasury  Price for such  redemption
date.

     Except as set forth above, the Notes shall not be redeemable by the Company
prior to maturity.

     The Notes shall not be entitled to the benefit of any sinking fund.

6.   Notice of Redemption

     Notice of redemption  shall be mailed at least 30 days but not more than 60
days before the redemption  date by first-class  mail to each Holder of Notes to
be redeemed at his  registered  address.  Notes in  denominations  of  principal
amount larger than $5,000 may be redeemed in part but only in integral multiples
of $1,000 in excess thereof.  If money sufficient to pay the redemption price of
and  accrued  and  unpaid  interest  on all Notes (or  portions  thereof)  to be
redeemed on the redemption  date is deposited with the Paying Agent on or before
11:00  a.m.  (New York  City  time) on the  redemption  date and  certain  other
conditions  are satisfied,  on and after such date interest  ceases to accrue on
such Notes (or such portions thereof) called for redemption.

7.   Registration Rights

     The Company is party to a Registration  Rights  Agreement,  dated as of May
27, 2005,  between the Company and Barclays Capital Inc., J.P. Morgan Securities
Inc. and the other Initial  Purchasers  named  therein,  pursuant to which it is
obligated to pay Additional Interest (as 

                                       A-5



defined  therein)  upon  the  occurrence  of  certain  events  specified  in the
Registration Rights Agreement.

8.   Denominations; Transfer; Exchange

     The Notes are in fully  registered form without coupons in denominations of
principal amount of $5,000 and integral multiples of $1,000 in excess thereof. A
Holder  may  register,  transfer  or  exchange  Notes  in  accordance  with  the
Indenture.  The Registrar may require a Holder,  among other things,  to furnish
appropriate  endorsements  or transfer  documents  and to pay any taxes and fees
required by law or permitted by the  Indenture.  The Registrar need not register
the transfer of or exchange any Notes  selected for redemption  (except,  in the
case of a Note to be  redeemed  in  part,  the  portion  of the  Note  not to be
redeemed)  for a period  beginning  15 days  before  the  mailing of a notice of
redemption of Notes to be redeemed and ending on the date of such mailing.

9.   Persons Deemed Owners

     The  registered  holder of this Note may be  treated as the owner of it for
all purposes.

10.  Unclaimed Money

     If money for the payment of principal or interest remains unclaimed for two
years after the date of payment of principal and interest, the Trustee or Paying
Agent  shall pay the money back to the  Company at its  request.  After any such
payment,  Holders entitled to the money must look only to the Company and not to
the Trustee for payment.

11.  Defeasance

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

12.  Amendment, Waiver

     Subject to certain exceptions set forth in the Indenture, (i) the Indenture
or the Notes may be amended with the written  consent of the Holders of at least
a majority in principal amount of the outstanding  Notes and (ii) any default or
noncompliance  with any  provision  of the  Indenture or the Notes may be waived
with the written consent of the Holders of a majority in principal amount of the
outstanding  Notes.   However,  the  Indenture  requires  the  consent  of  each
Noteholder  that  would  be  affected  for  certain   specified   amendments  or
modifications of the Indenture and the Notes.  Subject to certain exceptions set
forth in the Indenture,  without the consent of any Noteholder,  the Company and
the  Trustee  may  amend  the  Indenture  or the  Notes to cure  any  ambiguity,
omission, defect or inconsistency, or to comply with Article V of the Indenture,
or to add any additional Events of Default, or to add additional covenants of or
surrender  rights and powers  conferred  on the  Company,  or to add  additional
guarantees for the benefit of the  Noteholders,  or to secure the Notes pursuant
to the terms of the  Indenture,  or to add or appoint a  successor  or  separate
trustee or other agent, or to provide for the issuance of the 

                                      A-6


Exchange  Notes,  or to provide for the issuance of any Additional  Notes, or to
comply with any  requirements  in connection with qualifying the Indenture under
the  Trust  Indenture  Act,  or to  comply  with  the  rules  of any  securities
depository, or to provide for uncertificated Notes in addition to or in place of
certificated  Notes,  or to change any other  provision  if the change  does not
adversely affect the interests of any Noteholder in any material respect.

13.  Defaults and Remedies

     Under the Indenture,  Events of Default  include (i) default for 30 days in
payment of interest on the Notes;  (ii)  default in payment of  principal on the
Notes at maturity,  upon optional  redemption,  upon  declaration  or otherwise;
(iii)  failure by the Company to comply with any  covenant or  agreement  in the
Indenture  or the Notes,  subject to notice and lapse of time;  (iv)  default in
respect  of other  Debt of the  Company or any  Significant  Subsidiary  with an
aggregate  principal  amount then  outstanding in excess of  $50,000,000,  which
results in the acceleration of such Debt, subject to certain conditions; and (v)
certain  events  of  bankruptcy  or  insolvency  involving  the  Company  or any
Significant Subsidiary.

     If an Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in aggregate  principal  amount of the Notes may declare all the
Notes  to be due and  payable  immediately.  Certain  events  of  bankruptcy  or
insolvency involving the Company are Events of Default which shall result in the
Notes being due and payable  immediately  upon the  occurrence of such Events of
Default.

     Noteholders  may not enforce the  Indenture or the Notes except as provided
in the  Indenture.  The Trustee may refuse to enforce the Indenture or the Notes
unless it receives indemnity or security reasonably  satisfactory to it. Subject
to certain  limitations,  Holders of a majority in principal amount of the Notes
may direct the Trustee in its  exercise  of any trust or power.  The Trustee may
withhold from Noteholders  notice of any continuing  Default or Event of Default
(except a Default or Event of Default in payment of principal or interest) if it
in good  faith  determines  that  withholding  notice  is not  opposed  to their
interest.

14.  Trustee Dealings with the Company

     Subject to certain  limitations  set forth in the  Indenture,  the  Trustee
under the  Indenture,  in its individual or any other  capacity,  may become the
owner or pledgee of Notes and may  otherwise  deal with and collect  obligations
owed to it by the Company and may otherwise  deal with the Company with the same
rights it would have if it were not Trustee.

15.  No Recourse Against Others

     A director, officer, employee or stockholder of the Company, shall not have
any liability for any obligations of the Company under the Notes,  the Indenture
or the Registration Rights Agreement or for any claim based on, in respect of or
by reason of such  obligations  or their  creation.  By  accepting a Note,  each
Noteholder  waives and releases all such  liability.  The waiver and release are
part of the consideration for the issue of the Notes.

                                      A-7


16.  Authentication

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

17.  Abbreviations

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

18.  CUSIP and ISIN Numbers

     The Company has caused CUSIP and ISIN numbers and/or other similar  numbers
to be printed on the Notes and has  directed  the  Trustee to use CUSIP and ISIN
numbers  and/or other similar  numbers in notices of redemption as a convenience
to  Noteholders.  No  representation  is made as to the accuracy of such numbers
either as printed on the Notes or as contained in any notice of  redemption  and
reliance may be placed only on the other identification numbers placed thereon.

19.  Governing Law

     This Note shall be governed by, and construed in accordance  with, the laws
of the State of New York.

                                       A-8

1.   Interest

     THERMO  ELECTRON  CORPORATION,  a Delaware  corporation  (together with its
successors and assigns under the Indenture hereinafter referred to, being herein
called the "Company"),  promises to pay interest on the principal amount of this
Note at the rate of 5% per annum.

     The Company  shall pay  interest  semiannually  on June 1 and December 1 of
each year (each such date, an "Interest Payment Date"),  commencing on [December
1,  2005][first  interest  payment date relating to any Additional  Notes][first
interest payment date following  completion of the Exchange Offer referred to in
the Registration Rights Agreement]. Interest on the Notes shall accrue from [May
27, 2005] [date of issuance of any Additional  Notes][date  of interest  payment
date  immediately  preceding  completion  of Exchange  Offer  referred to in the
Registration  Rights Agreement],  or from the most recent date to which interest
has been paid on the Notes. Interest shall be computed on the basis of a 360-day
year comprised of twelve 30-day months.

2.   Method of Payment

     By no later than  10:00 a.m.  (New York City time) on the date on which any
principal  of or interest  on any Note is due and  payable,  the  Company  shall
irrevocably deposit with the Trustee or the Paying Agent money sufficient to pay
such principal and/or interest. The Company shall pay interest (except defaulted
interest)  to the  Persons who are  registered  Holders of Notes at the close of
business on the May 15 or November 15 next  preceding the Interest  Payment Date
even if Notes are  cancelled,  repurchased or redeemed after the record date and
on or before the Interest Payment Date. Holders must surrender Notes to a Paying
Agent to  collect  principal  payments.  The  Company  shall pay  principal  and
interest  in money of the  United  States  that at the time of  payment is legal
tender for  payment of public and  private  debts.  Payments in respect of Notes
represented  by a  Global  Note  (including  principal,  premium,  if  any,  and
interest)  shall be made by the transfer of immediately  available  funds to the
accounts  specified by The Depository  Trust  Company.  The Company may make all
payments in respect of a Definitive Note (including principal,  premium, if any,
and  interest)  by  mailing a check to the  registered  address  of each  Holder
thereof  or by  wire  transfer  to an  account  located  in  the  United  States
maintained by the payee.

3.   Paying Agent and Registrar

     JPMorgan Chase Bank, N.A., a national banking  association (the "Trustee"),
shall  initially act as Paying Agent and Registrar.  The Company may appoint and
change any Paying  Agent or  Registrar  without  notice to any  Noteholder.  The
Company or any of its domestically  organized wholly owned  Subsidiaries may act
as Paying Agent.

                                       B-3


4. Indenture

     The Company  issued the Notes under an  Indenture  dated as of May 27, 2005
(as it may be amended or  supplemented  from time to time in accordance with the
terms thereof, the "Indenture"),  between the Company and the Trustee. The terms
of the Notes  include  those stated in the  Indenture and those made part of the
Indenture  by  reference to the Trust  Indenture  Act of 1939 (15 U.S.C.  ss.ss.
77aaa-77bbbb)  as in effect on the date of the Indenture  (the "Trust  Indenture
Act").  Capitalized  terms used herein and not defined  herein have the meanings
ascribed thereto in the Indenture.  The Notes are subject to all such terms, and
Noteholders  are referred to the  Indenture  and the Trust  Indenture  Act for a
statement of those  terms.  To the extent any  provision of this Note  conflicts
with the express  provisions of the  Indenture,  the provisions of the Indenture
shall govern and be controlling.

of the  Exchange  Notes  referred  to in the  Indenture.  The Notes  include the
Initial  Notes  issued  on the  Issue  Date,  any  Additional  Notes  issued  in
accordance  with Section 2.15 of the Indenture and any Exchange  Notes issued in
exchange for the Initial Notes  pursuant to the  Indenture and the  Registration
Rights Agreement. The Initial Notes, any Additional Notes and the Exchange Notes
are treated as a single class of securities  under the Indenture.  The Indenture
imposes certain  limitations on the ability of the Company and its  subsidiaries
to create  liens,  enter into sale and  lease-back  transactions  and enter into
mergers and consolidations.

5.   Optional Redemption

     The Notes shall be  redeemable,  in whole or in part,  at any time and from
time to time, at the option of the Company,  at a redemption  price equal to the
greater  of (i) 100% of the  principal  amount of such Notes and (ii) the sum of
the present values of the remaining scheduled payments of principal and interest
thereon (exclusive of interest accrued to the date of redemption)  discounted to
the redemption date on a semiannual  basis (assuming a 360-day year comprised of
twelve 30-day months) at the Treasury Rate plus 15 basis points (the "Make-Whole
Amount"), plus accrued interest thereon to the redemption date.

     "Comparable  Treasury Issue" means the United States  Treasury  security or
securities  selected by an Independent  Investment Banker as having an actual or
interpolated  maturity  comparable  to the  remaining  term of the  Notes  to be
redeemed that would be utilized, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities
of a comparable maturity to the remaining term of the Notes to be redeemed.

     "Comparable  Treasury Price" means, with respect to any redemption date for
the Notes, (a) the average of the Reference  Treasury Dealer Quotations for such
redemption  date,  after  excluding  the  highest  and lowest of such  Reference
Treasury  Dealer  Quotations or (b) if the Company  obtains fewer than four such
Reference Treasury Dealer Quotations, the average of all such Reference Treasury
Dealer Quotations.

     "Independent Investment Banker" means one of the Reference Treasury Dealers
appointed by the Company.

                                      B-4


     "Reference  Treasury  Dealer" means each of Barclays  Capital Inc. and J.P.
Morgan  Securities Inc. or their respective  affiliates which are primary United
States government securities dealers, and their respective  successors,  and two
other  firms which are  primary  U.S.  government  securities  dealers  that the
Company selects; provided,  however, that if any of the foregoing shall cease to
be a primary  U.S.  government  securities  dealer in The City of New York,  the
Company  shall  substitute   therefor  another  such  primary  U.S.   government
securities dealer.

     "Reference Treasury Dealer Quotation" means, with respect to each Reference
Treasury  Dealer and any  redemption  date,  the average,  as  determined by the
Company,  of the  bid  and  asked  prices  for  the  Comparable  Treasury  Issue
(expressed  in each case as a  percentage  of its  principal  amount)  quoted in
writing to the Company by such  Reference  Treasury  Dealer as of 3:30 p.m., New
York time, on the third Business Day preceding such redemption date.

     "Treasury  Rate" means,  with respect to any redemption date for the Notes,
the rate per annum  equal to the  semiannual  equivalent  yield to  maturity  or
interpolated (on a day-count basis) of the Comparable Treasury Issue, assuming a
price for the  Comparable  Treasury  Issue  (expressed  as a  percentage  of its
principal  amount) equal to the Comparable  Treasury  Price for such  redemption
date.

     Except as set forth above, the Notes shall not be redeemable by the Company
prior to maturity

     The Notes shall not be entitled to the benefit of any sinking fund.

6.   Notice of Redemption

     Notice of redemption  shall be mailed at least 30 days but not more than 60
days before the redemption  date by first-class  mail to each Holder of Notes to
be redeemed at his  registered  address.  Notes in  denominations  of  principal
amount larger than $5,000 may be redeemed in part but only in integral multiples
of $1,000 in excess thereof.  If money sufficient to pay the redemption price of
and  accrued  and  unpaid  interest  on all Notes (or  portions  thereof)  to be
redeemed on the redemption  date is deposited with the Paying Agent on or before
11:00  a.m.  (New York  City  time) on the  redemption  date and  certain  other
conditions  are satisfied,  on and after such date interest  ceases to accrue on
such Notes (or such portions thereof) called for redemption.

7.   Denominations; Transfer; Exchange

     The Notes are in fully  registered form without coupons in denominations of
principal amount of $5,000 and integral multiples of $1,000 in excess thereof. A
Holder may register transfer or exchange Notes in accordance with the Indenture.
The Registrar may require a Holder,  among other things, to furnish  appropriate
endorsements or transfer documents and to pay any taxes and fees required by law
or permitted by the  Indenture.  The Registrar need not register the transfer of
or exchange any Notes selected for redemption  (except, in the case of a Note to
be redeemed in part,  the portion of the Note not to be  redeemed)  for a period
beginning  15 days before the mailing of a notice of  redemption  of Notes to be
redeemed and ending on the date of such mailing.

                                      B-5


8.   Persons Deemed Owners

     The  registered  holder of this Note may be  treated as the owner of it for
all purposes.

9.   Unclaimed Money

     If money for the payment of principal or interest remains unclaimed for two
years after the date of payment of principal and interest, the Trustee or Paying
Agent  shall pay the money back to the  Company at its  request.  After any such
payment,  Holders entitled to the money must look only to the Company and not to
the Trustee for payment.

10.  Defeasance

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

11.  Amendment, Waiver

     Subject to certain exceptions set forth in the Indenture, (i) the Indenture
or the Notes may be amended with the written  consent of the Holders of at least
a majority in principal amount of the outstanding  Notes and (ii) any default or
noncompliance  with any  provision  of the  Indenture or the Notes may be waived
with the written consent of the Holders of a majority in principal amount of the
outstanding  Notes.   However,  the  Indenture  requires  the  consent  of  each
Noteholder  that  would  be  affected  for  certain   specified   amendments  or
modifications of the Indenture and the Notes.  Subject to certain exceptions set
forth in the Indenture,  without the consent of any Noteholder,  the Company and
the  Trustee  may  amend  the  Indenture  or the  Notes to cure  any  ambiguity,
omission, defect or inconsistency, or to comply with Article V of the Indenture,
or to add any additional Events of Default, or to add additional covenants of or
surrender  rights and powers  conferred  on the  Company,  or to add  additional
guarantees for the benefit of the  Noteholders,  or to secure the Notes pursuant
to the terms of the  Indenture,  or to add or appoint a  successor  or  separate
trustee or other agent, or to provide for the issuance of the Exchange Notes, or
to provide  for the  issuance  of any  Additional  Notes,  or to comply with any
requirements  in  connection  with  qualifying  the  Indenture  under  the Trust
Indenture Act, or to comply with the rules of any securities  depository,  or to
provide for  uncertificated  Notes in  addition  to or in place of  certificated
Notes, or to change any other provision if the change does not adversely  affect
the interests of any Noteholder in any material respect.

12.  Defaults and Remedies

     Under the Indenture,  Events of Default  include (i) default for 30 days in
payment of interest on the Notes;  (ii)  default in payment of  principal on the
Notes at maturity,  upon optional  redemption,  upon  declaration  or otherwise;
(iii)  failure by the Company to comply with any  covenant or  agreement  in the
Indenture  or the Notes,  subject to notice and lapse of time;  (iv)  default in
respect  of other  Debt of the  Company or any  Significant  Subsidiary  with an
aggregate  principal  amount then  outstanding in excess of  $50,000,000,  which
results in the acceleration of 

                                      B-6



such Debt, subject to certain  conditions;  and (v) certain events of bankruptcy
or insolvency involving the Company or any Significant Subsidiary.

     If an Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in aggregate  principal  amount of the Notes may declare all the
Notes  to be due and  payable  immediately.  Certain  events  of  bankruptcy  or
insolvency involving the Company are Events of Default which shall result in the
Notes being due and payable  immediately  upon the  occurrence of such Events of
Default.

     Noteholders  may not enforce the  Indenture or the Notes except as provided
in the  Indenture.  The Trustee may refuse to enforce the Indenture or the Notes
unless it receives indemnity or security reasonably  satisfactory to it. Subject
to certain  limitations,  Holders of a majority in principal amount of the Notes
may direct the Trustee in its  exercise  of any trust or power.  The Trustee may
withhold from Noteholders  notice of any continuing  Default or Event of Default
(except a Default or Event of Default in payment of principal or interest) if it
in good  faith  determines  that  withholding  notice  is not  opposed  to their
interest.

13.  Trustee Dealings with the Company

     Subject to certain  limitations  set forth in the  Indenture,  the  Trustee
under the  Indenture,  in its individual or any other  capacity,  may become the
owner or pledgee of Notes and may  otherwise  deal with and collect  obligations
owed to it by the Company and may otherwise  deal with the Company with the same
rights it would have if it were not Trustee.

14.  No Recourse Against Others

     A director, officer, employee or stockholder of the Company, shall not have
any  liability  for any  obligations  of the  Company  or under the  Notes,  the
Indenture  or the  Registration  Rights  Agreement or for any claim based on, in
respect of or by reason of such  obligations or their  creation.  By accepting a
Note,  each Noteholder  waives and releases all such  liability.  The waiver and
release are part of the consideration for the issue of the Notes.

15.  Authentication

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

16.  Abbreviations

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

17. CUSIP and ISIN Numbers

     The Company has caused CUSIP and ISIN numbers and/or other similar  numbers
to be printed on the Notes and has  directed  the  Trustee to use CUSIP and ISIN
numbers  and/or 

                                      B-7


other similar  numbers in notices of redemption as a convenience to Noteholders.
No  representation  is made as to the accuracy of such numbers either as printed

     2. Registration  Under the Securities Act. (a) To the extent not prohibited
by any applicable law or applicable  interpretations  of the Staff,  the Company
shall use its reasonable  best efforts to (i) cause to be filed,  not later than
90 days  following the Closing Date, an Exchange  Offer  Registration  Statement
covering  an offer to the  Holders to  exchange  all the  Registrable  Notes for
Exchange  Notes,  (ii) cause the  Exchange  Offer  Registration  Statement to be
declared effective under the Securities Act within 180 days of the Closing Date,
(iii) have such Registration Statement remain effective until the closing of the
Exchange  Offer and (iv) cause the Exchange  Offer to be  consummated  not later
than 210 days  following  the Closing  Date.  The  Company  shall  commence  the
Exchange  Offer  promptly  after the Exchange  Offer  Registration  Statement is
declared  effective by the SEC and use its  reasonable  best efforts to complete
the Exchange Offer not later than 60 days after such effective date.

     The  Company  shall  commence  the  Exchange  Offer by mailing  the related
Prospectus,  appropriate letters of transmittal and other accompanying documents
to each Holder stating, in addition to such other disclosures as are required by
applicable law, substantially the following:

          (i)  that the Exchange  Offer is being made pursuant to this Agreement
               and that all Registrable  Notes validly tendered and not properly
               withdrawn will be accepted for exchange;

          (ii) the dates of acceptance for exchange  (which shall be a period of
               at least 20  Business  Days from the date such  notice is mailed)
               (the "Exchange Dates");

          (iii)that any  Registrable  Note not tendered or tendered and properly
               withdrawn will remain outstanding and continue to accrue interest
               but will not retain any rights under this Agreement;

          (iv) that any Holder  electing to have a  Registrable  Note  exchanged
               pursuant to the Exchange Offer will be required to surrender such
               Registrable  Note,  together  with  the  appropriate  letters  of
               transmittal,  to the institution  and at the address  (located in
               the Borough of Manhattan, The City of New York) and in the manner
               specified  in the  notice,  prior to the close of business on the
               last Exchange Date; and

          (v)  that any Holder will be entitled to withdraw  its  election,  not
               later than the close of business on the last  Exchange  Date,  by
               sending to the  institution  and at the  address  (located in the
               Borough  of  Manhattan,  The City of New York)  specified  in the
               notice,  a  telegram,  telex,  facsimile  transmission  or letter
               setting forth the name of such Holder,  the  principal  amount of
               Registrable  Notes  delivered  for exchange and a statement  that
               such  Holder is  withdrawing  its  election  to have  such  Notes
               exchanged.

                                       5


     As a condition to  participating  in the Exchange  Offer,  a Holder will be
required to represent to the Company that (i) any Exchange  Notes to be received
by it will be acquired in the ordinary course of its business,  (ii) at the time
of the commencement of the Exchange Offer it has no arrangement or understanding
with any Person to  participate in the  distribution  (within the meaning of the
Securities  Act) of the Exchange  Notes in violation  of the  provisions  of the
Securities  Act, (iii) it is not an "affiliate"  (within the meaning of Rule 405
under  the  Securities  Act)  of the  Company  and  (iv)  if  such  Holder  is a
broker-dealer  that will receive  Exchange Notes for its own account in exchange
for Registrable  Notes that were acquired as a result of  market-making or other
trading  activities,  then such Holder will deliver a Prospectus  in  connection
with any resale of such Exchange Notes.

     As soon as practicable after the last Exchange Date, the Company shall:

          (i)  accept for exchange Registrable Notes or portions thereof validly
               tendered  and not  properly  withdrawn  pursuant to the  Exchange
               Offer; and

          (ii) deliver,   or  cause  to  be   delivered,   to  the  Trustee  for
               cancellation  all  Registrable   Notes  or  portions  thereof  so
               accepted  for  exchange by the  Company and issue,  and cause the
               Trustee to  promptly  authenticate  and  deliver to each  Holder,
               Exchange Notes equal in principal  amount to the principal amount
               of the Registrable Notes surrendered by such Holder.

     The Company shall use its reasonable  best efforts to complete the Exchange
Offer as provided above and shall comply with the applicable requirements of the
Securities  Act, the Exchange Act and other  applicable  laws and regulations in
connection with the Exchange  Offer.  The Exchange Offer shall not be subject to
any conditions, other than that:

          (i)  the  Exchange  Offer  does  not  violate  any  applicable  law or
               applicable interpretations of the Staff;

          (ii) that no action  or  proceeding  shall  have  been  instituted  or
               threatened  in any  court  or by  any  governmental  agency  with
               respect to the Exchange Offer which,  in the Company's  judgment,
               would  reasonably  be  expected  to impair its ability to proceed
               with the Exchange Offer; and

          (iii)any such other  conditions as shall be agreed upon by the Company
               and the Initial Purchasers.

     (b) In the event that (i) the Company  determines  that the Exchange  Offer
Registration  provided for in Section 2(a) above is not  available or may not be
completed as soon as  practicable  after the last  Exchange  Date because (A) it
would violate any applicable law or applicable interpretations of the Staff, (B)
an 

                                       6


action or  proceeding  has been  instituted or threatened in any court or by any
governmental  agency with respect to the Exchange Offer which,  in the Company's
judgment, would reasonably be expected to impair its ability to proceed with the
Exchange  Offer or (C) of any such other  conditions as have been agreed upon by
the Company and the Initial  Purchasers,  (ii) the Exchange Offer is not for any
other reason completed by December 23, 2005 or (iii) any Initial Purchaser shall
so reasonably  request in connection with any offer or sale of Registrable Notes
held by the Initial  Purchaser  and not eligible to be exchanged in the Exchange
Offer, the Company shall use its reasonable best efforts to cause to be filed as
soon as reasonably practicable after such determination, date or request, as the
case may be, a Shelf  Registration  Statement  providing for the sale of all the
Registrable  Notes by the Holders  thereof  and to have such Shelf  Registration
Statement declared effective by the SEC.

     In the event that the  Company  is  required  to file a Shelf  Registration
Statement  solely as a result of the  matters  referred to in clause (ii) of the
preceding  paragraph  but the  Exchange  Offer is completed on a date later than
December 23, 2005,  upon  consummation of the Exchange Offer the Company will no
longer  be  required  to  file,   have   declared   effective  or  continue  the
effectiveness of the Shelf  Registration  Statement pursuant to such clause (ii)
(without prejudice to its obligations under clause (i) or (iii) of the preceding
paragraph).

     In the event that the  Company  is  required  to file a Shelf  Registration
Statement  solely as a result of the matters  referred to in clause (iii) of the
second preceding paragraph, the Company shall use its reasonable best efforts to
file and have declared  effective by the SEC both an Exchange Offer Registration
Statement  pursuant to Section 2(a) with respect to all Registrable  Notes and a
Shelf  Registration  Statement (which may be a combined  Registration  Statement
with the Exchange Offer Registration Statement) with respect to offers and sales
of  Registrable  Notes held by the Initial  Purchasers  after  completion of the
Exchange Offer.

     The Company  agrees to use its  reasonable  best  efforts to keep the Shelf
Registration Statement continuously effective until the expiration of the period
referred  to in Rule  144(k) (or any  similar  rule then in force,  but not Rule
144A) under the  Securities  Act with respect to the  Registrable  Notes or such
shorter period that will terminate when all the Registrable Notes covered by the
Shelf  Registration  Statement have been sold pursuant to the Shelf Registration
Statement (the "Shelf Effectiveness Period").  Subject to the Company's right to
temporarily  suspend the Shelf  Registration  Statement pursuant to Section 3(c)
hereof, the Company further agrees to supplement or amend the Shelf Registration
Statement and the related  Prospectus if required by the rules,  regulations  or
instructions  applicable to the  registration  form used by the Company for such
Shelf Registration  Statement or by the Securities Act or by any other rules and
regulations  thereunder for shelf  registration or if reasonably  


                                       7


requested by a Holder of Registrable Notes with respect to information  relating
to such  Holder,  and to use its  reasonable  best  efforts  to  cause  any such
amendment  to  become  effective  and  such  Shelf  Registration  Statement  and
Prospectus  to become  usable as soon as  thereafter  practicable.  The  Company
agrees  to  furnish  to the  Holders  of  Registrable  Notes  copies of any such
supplement or amendment promptly after its being used or filed with the SEC.

     (c) The Company shall pay all Registration  Expenses in connection with any
registration  pursuant to Section 2(a) or Section 2(b) hereof. Each Holder shall
pay all  underwriting  discounts  and  commissions,  brokerage  commissions  and
transfer  taxes,  if any,  relating to the sale or  disposition of such Holder's
Registrable Notes pursuant to the Shelf Registration Statement.

     (d) An Exchange  Offer  Registration  Statement  pursuant  to Section  2(a)
hereof or a Shelf  Registration  Statement  pursuant to Section 2(b) hereof will
not be deemed to have become effective unless it has been declared  effective by
the SEC.

     In the event that either the  Exchange  Offer is not  completed by December
23,  2005 or the  Shelf  Registration  Statement,  if  required  hereby,  is not
declared  effective  on or prior to January 23, 2006,  the interest  rate on the
Registrable  Notes shall be  increased  by 0.25% per annum for the first  90-day
period (or portion thereof) after the above-specified  relevant date, which rate
shall be increased by 0.25% per annum at the beginning of the subsequent  90-day
period and continue thereafter  (provided that the maximum aggregate increase in
the interest rate shall in no event exceed 0.50% per annum) until such date that
the Exchange Offer is completed or the Shelf Registration Statement, if required
hereby,  is declared  effective by the SEC or the Notes become  freely  tradable
under the Securities Act, on which date such additional  interest shall cease to
accrue  and the  interest  rate on the  Registrable  Notes  will  revert  to the
original interest rate. Any amounts payable under this paragraph shall be deemed
"Additional Interest" for purposes of this Agreement.

     If the Shelf Registration  Statement, if required hereby, has been declared
effective  and  thereafter  either  ceases  to be  effective  or the  Prospectus
contained therein ceases to be usable at any time during the Shelf Effectiveness
Period,  and such failure to remain  effective or usable exists for more than 30
days (whether or not consecutive) in any 12-month  period,  the interest rate on
the Registrable Notes shall be increased by 0.25% per annum for the first 90-day
period (or portion  thereof)  beginning on the 31st day in such 12-month period,
which  rate  shall be  increased  by 0.25%  per  annum at the  beginning  of the
subsequent  90-day  period and continue  thereafter  (provided  that the maximum
aggregate  increase  in the  interest  rate shall in no event  exceed  0.50% per
annum)  until  such date that the Shelf  Registration  Statement  has again been
declared  effective or the Prospectus  again becomes usable,  on which date such
additional  interest  shall  cease  to  accrue  and  the  interest  rate  on the
Registrable Notes will revert to the original interest rate. Any amounts payable
under this

                                       8


paragraph  shall  also be deemed  "Additional  Interest"  for  purposes  of this
Agreement.

     (e) Without limiting the remedies  available to the Initial  Purchasers and
the Holders,  the Company acknowledges that any failure by the Company to comply
with their  obligations under Section 2(a) and Section 2(b) hereof may result in
material  irreparable  injury to the Initial Purchasers or the Holders for which
there is no  adequate  remedy at law,  that it will not be  possible  to measure
damages for such injuries  precisely and that, in the event of any such failure,
the Initial  Purchasers  or any Holder may obtain such relief as may be required
to specifically enforce the Company's obligations under Section 2(a) and Section
2(b) hereof.

     3. Registration Procedures. (a) In connection with its obligations pursuant
to Section 2(a) and Section 2(b) hereof,  the Company shall as  expeditiously as
reasonably possible:

     (i)  prepare  and  file  with  the  SEC a  Registration  Statement  on  the
appropriate  form under the Securities  Act, which form (x) shall be selected by
the Company,  (y) shall, in the case of a Shelf  Registration,  be available for
the sale of the Registrable Notes by the Holders thereof and (z) shall comply as
to form in all material  respects with the  requirements  of the applicable form
and include all financial  statements required by the SEC to be filed therewith;
and use its  reasonable  best  efforts to cause such  Registration  Statement to
become  effective and remain  effective for the applicable  period in accordance
with Section 2 hereof;

     (ii) use its reasonable  best efforts to prepare and file with the SEC such
amendments and post-effective  amendments to each Registration  Statement as may
be necessary to keep such  Registration  Statement  effective for the applicable
period in accordance  with Section 2 hereof and use its reasonable  best efforts
to  cause  each  Prospectus  to  be  supplemented  by  any  required  prospectus
supplement and, as so  supplemented,  to be filed pursuant to Rule 424 under the
Securities  Act; and use its  reasonable  best  efforts to keep each  Prospectus
current  during the period  described  in Section 4(3) of and Rule 174 under the
Securities  Act that is  applicable to  transactions  by brokers or dealers with
respect to the Registrable Notes or Exchange Notes;

     (iii)  in the  case of a Shelf  Registration,  furnish  to each  Holder  of
Registrable Notes, to counsel for the Initial Purchasers, to the one counsel for
such Holders and to each Underwriter of an Underwritten  Offering of Registrable
Notes, if any,  without charge,  as many copies as reasonably  requested of each
Prospectus,   including  each  preliminary  Prospectus,  and  any  amendment  or
supplement  thereto as each such Holder or  Underwriter,  as  applicable,  might
reasonably  request, in order to facilitate the sale or other disposition of the
Registrable Notes thereunder; and, subject to the Company's right to temporarily
suspend the Shelf  Registration  Statement  pursuant to Section 3(c) hereof, the

                                       9



Company  consents to the use of such  Prospectus and any amendment or supplement
thereto in  accordance  with  applicable  law and this  Agreement by each of the
Holders of Registrable  Notes and any such  Underwriters  in connection with the
offering  and  sale  of the  Registrable  Notes  covered  by  and in the  manner
described  in  such  Prospectus  or  any  amendment  or  supplement  thereto  in
accordance with applicable law;

     (iv) use its reasonable best efforts to register or qualify the Registrable
Notes  under  all  applicable   state  securities  or  blue  sky  laws  of  such
jurisdictions  as any Holder of  Registrable  Notes  covered  by a  Registration
Statement  shall  reasonably  request  in  writing  by the time  the  applicable
Registration  Statement is declared  effective by the SEC;  cooperate  with such
Holders in  connection  with any filings  required to be made with the  National
Association  of  Securities  Dealers,  Inc.;  and do any and all other  acts and
things that may be  reasonably  necessary  or advisable to enable each Holder to
complete the  disposition in each such  jurisdiction  of the  Registrable  Notes
owned by such  Holder;  provided  that the Company  shall not be required to (1)
qualify as a foreign corporation or other entity or as a dealer in securities in
any such  jurisdiction  where it would not  otherwise be required to so qualify,
(2) file any general  consent to service of process in any such  jurisdiction or
(3) subject itself to taxation in any such jurisdiction if it is not so subject;

     (v) notify counsel for the Initial  Purchasers  and, in the case of a Shelf
Registration,  notify each Holder of  Registrable  Notes and the one counsel for
the Holders promptly and, if requested by any such Holder or counsel in writing,
confirm  such advice in writing  (1) when a  Registration  Statement  has become
effective  and when any  post-effective  amendment  thereto  has been  filed and
becomes  effective,  (2)  of any  request  by the  SEC or any  state  securities
authority  for  amendments  and  supplements  to a  Registration  Statement  and
Prospectus or for additional  information  after the Registration  Statement has
become  effective,  (3)  of the  issuance  by the  SEC or any  state  securities
authority  of any stop order  suspending  the  effectiveness  of a  Registration
Statement or the initiation of any proceedings for that purpose, (4) if, between
the effective date of a Shelf Registration Statement and the closing of any sale
of Registrable Notes covered thereby,  the representations and warranties of the
Company contained in any underwriting  agreement,  securities sales agreement or
other similar  agreement,  if any,  relating to an offering of such  Registrable
Notes  cease to be true and correct in all  material  respects or if the Company
receives any notification with respect to the suspension of the qualification of
the  Registrable  Notes for sale in any  jurisdiction  or the  initiation of any
proceeding for such purpose, (5) of the happening of any event during the period
a Shelf  Registration  Statement is effective  that makes any statement  made in
such  Shelf  Registration  Statement  or the  related  Prospectus  untrue in any
material  respect  or that  requires  the  making of any  changes  in such Shelf
Registration Statement or Prospectus in order to make the statements therein not
misleading,  (6)  of any  determination  by the  Company  that a  post-effective
amendment  to a  Registration  Statement  would  be  appropriate  and (7) of the
receipt by the Company of any notification with respect 

                                       10



to the suspension of the  qualification of the Registrable Notes or the Exchange
Notes,  as the case may be, for sale in any  jurisdiction  or the  initiation or
threatening of any proceeding for such purpose;

     (vi) use its reasonable  best efforts to obtain the withdrawal of any order
suspending  the  effectiveness  of a  Registration  Statement  at  the  earliest
reasonable  possible moment and provide  immediate  notice to each Holder of the
withdrawal of any such order;

     (vii)  in the  case of a Shelf  Registration,  furnish  to each  Holder  of
Registrable  Notes,  without  charge,  at  least  one  conformed  copy  of  each
Registration  Statement and any  post-effective  amendment  thereto (without any
documents  incorporated  therein  by  reference  or  exhibits  thereto,   unless
requested);

     (viii) in the case of a Shelf  Registration,  cooperate with the Holders of
Registrable  Notes  to  facilitate  the  timely   preparation  and  delivery  of
certificates  representing  Registrable  Notes  to be sold and not  bearing  any
restrictive  legends  and  enable  such  Registrable  Notes to be issued in such
denominations  and registered in such names  (consistent  with the provisions of
the Indenture) as such Holders may reasonably  request at least one Business Day
prior to the closing of any sale of Registrable Notes;

     (ix) in the case of a Shelf Registration,  upon the occurrence of any event
contemplated by Section  3(a)(v)(5)  hereof,  use its reasonable best efforts to
prepare and file with the SEC a supplement or  post-effective  amendment to such
Shelf  Registration   Statement  or  the  related  Prospectus  or  any  document
incorporated  therein by reference or file any other required  document so that,
as thereafter  delivered to purchasers of the Registrable Notes, such Prospectus
will not  contain  any untrue  statement  of a material  fact or omit to state a
material  fact  necessary to make the  statements  therein,  in the light of the
circumstances under which they were made, not misleading;  and the Company shall
notify the  Holders of  Registrable  Notes to suspend use of the  Prospectus  as
promptly as practicable  after the occurrence of such an event, and such Holders
hereby agree to suspend use of the  Prospectus  until the Company has amended or
supplemented the Prospectus to correct such misstatement or omission;

     (x) a reasonable  time prior to the filing of any  Registration  Statement,
any  Prospectus,  or any amendment to a  Registration  Statement or amendment or
supplement  to a  Prospectus,  provide  copies of such  document  to the Initial
Purchasers  and  their  counsel  (and,  in  the  case  of a  Shelf  Registration
Statement,  to the  Holders of  Registrable  Notes and the one  counsel  for the
Holders)  and  make  such of the  representatives  of the  Company  as  shall be
reasonably  requested by the Initial  Purchasers  or their  counsel (and, in the
case of a Shelf  Registration  Statement,  the Majority  Holders of  Registrable
Notes or the one counsel  for the  Holders)  available  for  discussion  of such
document;  and the  Company  shall not,  at any time after  initial  filing of a
Registration Statement,  file 

                                       11




any Prospectus, or any amendment of or supplement to a Registration Statement or
a  Prospectus,  of which the Initial  Purchasers  and their counsel (and, in the
case of a Shelf Registration Statement, the Holders of Registrable Notes and the
one  counsel  for the  Holders)  shall  not have  previously  been  advised  and
furnished a copy or to which the Initial  Purchasers  or their  counsel (and, in
the case of a Shelf Registration Statement,  the Holders of Registrable Notes or
the  one  counsel  for  the  Holders)  shall  reasonably  and  promptly  object.
Notwithstanding the foregoing,  the Company shall not be required to provide the
Initial  Purchasers  or their  counsel (and in the case of a Shelf  Registration
Statement, the Holders of Registrable Notes or the one counsel for the Holders),
prior to filing,  with  copies of any  document  that is to be  incorporated  by
reference into a Registration  Statement or a Prospectus after initial filing of
a Registration  Statement or to refrain from filing any such document that is to
be so incorporated by reference to which the Initial Purchasers or their counsel
(and, in the case of a Shelf Registration Statement,  the Holders of Registrable
Notes or the one counsel for the Holders)  shall  reasonably  and timely object;
provided that the Company  shall,  to the extent  reasonably  practicable in the
light of circumstances,  advise the Initial Purchasers or their counsel (and, in
the case of a Shelf Registration Statement,  the Holders of Registrable Notes or
the one  counsel  for the  Holders)  as to the  form and  substance  of any such
document that is to be so  incorporated  by reference  prior to its filing;  and
provided,  further,  that the  foregoing  provision  shall not apply to  Current
Reports filed on Form 8-K that, in the reasonable judgment of the Company, would
not be material to an investor in the Exchange Notes;

     (xi) obtain a CUSIP number for all Exchange Notes or Registrable  Notes, as
the case may be, not later than the effective date of a Registration Statement;

     (xii) cause the Indenture to be qualified  under the Trust Indenture Act in
connection with the registration of the Exchange Notes or Registrable  Notes, as
the case may be;  cooperate  with the  Trustee  and the  Holders to effect  such
changes to the Indenture as may be required for the Indenture to be so qualified
in accordance  with the terms of the Trust  Indenture Act; and execute,  and use
its  reasonable  best efforts to cause the Trustee to execute,  all documents as
may be  required  to  effect  such  changes  and all other  forms and  documents
required to be filed with the SEC to enable the  Indenture to be so qualified in
a timely manner;

     (xiii) in the case of a Shelf  Registration,  make available for inspection
by a  representative  designated by the Majority Holders (an  "Inspector"),  any
Underwriter participating in any disposition pursuant to such Shelf Registration
Statement,  the one  counsel  for  the  Holders  of  Registrable  Notes  and one
accounting  firm  designated  by the  Majority  Holders  and any  attorneys  and
accountants  designated  by  such  Underwriter,  at  reasonable  times  and in a
reasonable  manner,  all pertinent  financial and other  records,  documents and
properties  of the  Company  reasonably  requested,  and  cause  the  respective


                                       12

  

officers,  directors  and  employees  of the  Company to supply all  information
reasonably requested by any such Inspector,  Underwriter, attorney or accountant
in connection  with a Shelf  Registration  Statement;  provided that if any such
information is identified by the Company as being  confidential  or proprietary,
each Person receiving such information shall take such actions as are reasonably
necessary to protect the  confidentiality of such information to the extent such
action is otherwise not inconsistent  with, an impairment of or in derogation of
the rights and interests of any Inspector, Holder or Underwriter);

     (xiv) in the case of a Shelf Registration,  use its reasonable best efforts
to cause all  Registrable  Notes to be listed on any securities  exchange or any
automated quotation system on which similar securities issued by the Company are
then listed if requested in writing by the Majority Holders,  to the extent such
Registrable Notes satisfy applicable listing requirements;

     (xv) if reasonably  requested in writing by any Holder of Registrable Notes
covered by a Shelf Registration Statement, as promptly as reasonably practicable
include in a Prospectus supplement or post-effective  amendment such information
with  respect to such Holder as such Holder  reasonably  requests to be included
therein and promptly make all required filings of such Prospectus  supplement or
such post-effective  amendment as soon as the Company has received  notification
of the matters to be so included in such filing; and

     (xvi)  in the  case of a Shelf  Registration,  enter  into  such  customary
agreements and take all such other  reasonable  actions in connection  therewith
(including  those requested in writing by the Holders of a majority in principal
amount of the  Registrable  Notes being sold) in order to expedite or facilitate
the  disposition of such  Registrable  Notes  including,  but not limited to, an
Underwritten Offering and in such connection,  (1) to the extent possible,  make
such  representations and warranties to the Holders and any Underwriters of such
Registrable  Notes  with  respect  to  the  business  of  the  Company  and  its
subsidiaries   and  the   Registration   Statement,   Prospectus  and  documents
incorporated by reference or deemed  incorporated by reference,  if any, in each
case,  in form,  substance  and  scope as are  customarily  made by  issuers  to
underwriters  in  underwritten  offerings and confirm the same at reasonable and
customary  times if  reasonably  requested,  (2) in the case of an  Underwritten
Offering, obtain opinions of counsel to the Company (which counsel and opinions,
in form,  scope and substance,  shall be reasonably  satisfactory to the Holders
and such  Underwriters,  counsel to the Underwriters and the one counsel for the
Holders)  addressed to each selling Holder and Underwriter of Registrable Notes,
covering the matters  customarily  covered in opinions requested in underwritten
offerings, (3) in the case of an Underwritten Offering, obtain "comfort" letters
from the  independent  certified  public  accountants  of the Company  (and,  if
necessary,  any other  certified  public  accountant  of any  subsidiary  of the
Company,  or of  any  business  acquired  by the  Company  for  which  financial
statements  and  financial  data  are  or are  required  to be  included  in the
Registration  Statement)  addressed to each selling  Holder and  Underwriter  of


                                       13



Registrable  Notes, such letters to be in customary form and covering matters of
the  type   customarily   covered  in  "comfort"   letters  in  connection  with
underwritten offerings and (4) deliver such documents and certificates as may be
reasonably  requested  by the Holders of a majority in  principal  amount of the
Registrable  Notes  being sold or the  Underwriters,  and which are  customarily
delivered in underwritten  offerings,  to evidence the continued validity of the
representations  and warranties of the Company made pursuant to clause (1) above
and to  evidence  compliance  with  any  customary  conditions  contained  in an
underwriting agreement.

     (b) In the case of a Shelf Registration Statement,  the Company may require
each  Holder of  Registrable  Notes to furnish to the Company  such  information
regarding  such  Holder  and the  proposed  disposition  by such  Holder of such
Registrable  Notes as the  Company may from time to time  reasonably  request in
writing.

     (c)  In  the  case  of a  Shelf  Registration  Statement,  each  Holder  of
Registrable  Notes agrees  that,  upon receipt of any notice from the Company of
the  happening  of any event of the kind  described  in  Section  3(a)(v)(3)  or
3(a)(v)(5)  hereof,  such  Holder  will  forthwith  discontinue  disposition  of
Registrable  Notes  pursuant  to the Shelf  Registration  Statement  until  such
Holder's  receipt  of the  copies  of the  supplemented  or  amended  Prospectus
contemplated by Section 3(a)(ix) hereof and, if so directed by the Company, such
Holder  will  deliver to the Company  all copies in its  possession,  other than
permanent  file  copies  then in such  Holder's  possession,  of the  Prospectus
covering such  Registrable  Notes that is current at the time of receipt of such
notice.

     (d) If the Company shall give any notice pursuant to Section 3(c) hereof to
suspend the  disposition of Registrable  Notes pursuant to a Shelf  Registration
Statement,  the  Company  shall  extend  the  period  during  which  such  Shelf
Registration  Statement shall be maintained effective pursuant to this Agreement
by the  number of days  during  the period  from and  including  the date of the
giving  of such  notice  to and  including  the date  when the  Holders  of such
Registrable  Notes shall have  received  copies of the  supplemented  or amended
Prospectus necessary to resume such dispositions;  provided,  however, that such
period shall not be extended beyond the two-year period beginning on the Closing
Date  contemplated in Rule 144(k) under the Securities Act. The Company may give
any such notice only twice  during any 365-day  period and any such  suspensions
shall not exceed 30 days for each  suspension  and there  shall not be more than
two suspensions in effect during any 365-day period.

     (e) The  Holders  of  Registrable  Notes  covered  by a Shelf  Registration
Statement who desire to do so may sell such Registrable Notes in an Underwritten
Offering. In any such Underwritten  Offering,  the investment bank or investment
banks and manager or managers (each an  "Underwriter")  that will administer the
offering  will be selected by the Holders of a majority in  principal  amount of
the Registrable Notes included in such offering and be subject to the


                                       14



consent of the Company,  (which consent shall not be unreasonably  withheld) and
such Holders shall be responsible  for paying all  underwriting  commissions and
discounts in connection therewith.

     4.  Participation  of  Broker-Dealers  in Exchange Offer. (a) The Staff has
taken the position that any  broker-dealer  that receives Exchange Notes for its
own account in the Exchange  Offer in exchange  for Notes that were  acquired by
such  broker-dealer as a result of market-making or other trading  activities (a
"Participating  Broker-Dealer") may be deemed to be an "underwriter"  within the
meaning  of the  Securities  Act and  must  deliver  a  prospectus  meeting  the
requirements  of the  Securities  Act in  connection  with  any  resale  of such
Exchange Notes.

     The  Company  understands  that  it is the  Staff's  position  that  if the
Prospectus  contained in the Exchange Offer  Registration  Statement  includes a
plan of distribution containing a statement to the above effect and the means by
which Participating Broker-Dealers may resell the Exchange Notes, without naming
the  Participating  Broker-Dealers  or specifying  the amount of Exchange  Notes
owned by them, such Prospectus may be delivered by Participating  Broker-Dealers
to satisfy their  prospectus  delivery  obligation  under the  Securities Act in
connection with resales of Exchange Notes for their own accounts, so long as the
Prospectus otherwise meets the requirements of the Securities Act.

     (b) In light of the above, and notwithstanding the other provisions of this
Agreement, the Company agrees to amend or supplement the Prospectus contained in
the Exchange Offer  Registration  Statement for a period of up to 120 days after
the last Exchange Date (as such period may be extended  pursuant to Section 3(d)
of this  Agreement),  if requested by the Initial  Purchasers  or by one or more
Participating Broker-Dealers, in order to expedite or facilitate the disposition
of any  Exchange  Notes  by  Participating  Broker-Dealers  consistent  with the
positions of the Staff recited in Section 4(a) above. The Company further agrees
that Participating Broker-Dealers shall be authorized to deliver such Prospectus
during such period in connection  with the resales  contemplated by this Section
4.

     (c) The Initial  Purchasers  shall have no  liability to the Company or any
Holder with respect to any request  that they may make  pursuant to Section 4(b)
above.

     5.  Indemnification  and Contribution.  (a) The Company agrees to indemnify
and hold  harmless  each Initial  Purchaser  and each Holder,  their  respective
affiliates,  directors  and officers  and each Person,  if any, who controls any
Initial  Purchaser  or any  Holder  within  the  meaning  of  Section  15 of the
Securities  Act or Section 20 of the Exchange  Act, from and against any and all
losses, claims, damages and liabilities  (including,  without limitation,  legal
fees and  other  expenses  incurred  in  connection  with any  suit,  action  or
proceeding or any claim asserted, as such fees and expenses are incurred),  that
arise out of,  or 

                                       15


are based upon, any untrue  statement or alleged untrue  statement of a material
fact contained in any  Registration  Statement or any Prospectus or any omission
or alleged  omission  to state  therein a material  fact  required  to be stated
therein or necessary in order to make the  statements  therein,  in the light of
the circumstances under which they were made, not misleading,  except insofar as
such losses, claims, damages or liabilities arise out of, or are based upon, any
untrue  statement or omission or alleged  untrue  statement or omission  made in
reliance upon and in  conformity  with any  information  relating to any Initial
Purchaser  or  information  relating to any Holder  furnished  to the Company in
writing through Barclays Capital Inc.,  JPMorgan or any selling Holder expressly
for use therein; provided, that with respect to any untrue statement or omission
or alleged  untrue  statement  or  omission  that was  contained  or made in any
related  preliminary  Prospectus,  the  indemnity  agreement  contained  in this
paragraph (a) shall not inure to the benefit of any Initial Purchaser, Holder or
any  of  their  respective  affiliates,   directors  or  officers  or  any  such
controlling person to the extent that any such loss, claim,  damage or liability
results from the fact that both (i) a copy of the final  Prospectus was not sent
or given by such Initial  Purchaser or Holder to such Person  asserting any such
loss, claim, damage or liability at or prior to the written  confirmation of the
sale of such  Registrable  Notes or  Exchange  Notes to such Person and (ii) the
untrue  statement  in or  omission  from a related  preliminary  Prospectus  was
corrected in the final Prospectus,  as it may have been amended or supplemented,
unless,  in either  case,  such  failure to deliver the final  Prospectus  was a
result of non-compliance by the Company with the provisions of Section 3 hereof.
In connection with any Underwritten Offering permitted by Section 3, the Company
will also  indemnify the  Underwriters,  if any,  selling  brokers,  dealers and
similar  securities  industry  professionals  participating in the distribution,
their  respective  affiliates and each Person who controls such Persons  (within
the meaning of the  Securities  Act and the Exchange  Act) to the same extent as
provided above with respect to the  indemnification of the Holders, if requested
in connection with any Registration Statement.

     (b) Each Holder  agrees,  severally and not jointly,  to indemnify and hold
harmless the Company,  the Initial Purchasers and the other selling Holders, the
directors  of  the  Company,   each  officer  of  the  Company  who  signed  the
Registration  Statement and each Person,  if any, who controls the Company,  any
Initial  Purchaser and any other selling Holder within the meaning of Section 15
of the  Securities  Act or Section 20 of the  Exchange Act to the same extent as
the  indemnity  set forth in Section  5(a) above,  but only with  respect to any
losses, claims, damages or liabilities that arise out of, or are based upon, any
untrue  statement or omission or alleged  untrue  statement or omission  made in
reliance upon and in  conformity  with any  information  relating to such Holder
furnished to the Company in writing through Barclays  Capital Inc.,  JPMorgan or
any  selling  Holder  expressly  for use in any  Registration  Statement  or any
Prospectus.

     (c)  If  any  suit,  action,  proceeding  (including  any  governmental  or
regulatory investigation),  claim or demand shall be brought or asserted against
any Person in respect of which  indemnification may be sought pursuant to either


                                       16



Section  5(a) or 5(b)  above,  such  Person  (the  "Indemnified  Person")  shall
promptly notify the Person against whom such  indemnification may be sought (the
"Indemnifying  Person")  in  writing;  provided  that the  failure to notify the
Indemnifying  Person  shall not relieve it from any  liability  that it may have
under this  Section 5 except to the extent that it has been  prejudiced  by such
failure;  and  provided,  further,  that the failure to notify the  Indemnifying
Person  shall  not  relieve  it  from  any  liability  that  it may  have  to an
Indemnified  Person  otherwise than under this Section 5. If any such proceeding
shall be brought or  asserted  against an  Indemnified  Person and it shall have
notified the  Indemnifying  Person  thereof,  the  Indemnifying  Person shall be
entitled to participate  therein and, to the extent it wishes,  jointly with any
other similarly notified  Indemnifying Party, to assume the defense thereof with
counsel  reasonably  satisfactory  to the  Indemnified  Person to represent  the
Indemnified Person and any others entitled to  indemnification  pursuant to this
Section 5 that the  Indemnifying  Person may  designate in such  proceeding  and
shall pay the fees and expenses of such counsel related to such  proceeding,  as
incurred.  After notice from the Indemnifying  Party to the Indemnified Party of
its election to assume the defense of such proceeding,  the  Indemnifying  Party
shall not be liable to the Indemnified  Party under this Section 5 for any legal
or other expenses  subsequently  incurred by the Indemnified Party in connection
with the defense thereof other than reasonable costs of investigation; provided,
however,  that in any such  proceeding,  any  Indemnified  Person shall have the
right to retain its own counsel, but the fees and expenses of such counsel shall
be at the expense of such Indemnified Person unless (i) the Indemnifying  Person
and the Indemnified Person shall have mutually agreed to the contrary;  (ii) the
Indemnifying  Person  has  failed  within a  reasonable  time to retain  counsel
reasonably satisfactory to the Indemnified Person; or (iii) the named parties in
any  such  proceeding   (including  any  impleaded  parties)  include  both  the
Indemnifying  Person  and the  Indemnified  Person  and  representation  of both
parties by the same  counsel,  in the  reasonable  judgment  of the  Indemnified
Person,  would be inappropriate due to actual or potential  differing  interests
between them or differing legal defenses available to them. It is understood and
agreed that the Indemnifying Person shall not, in connection with any proceeding
or  related  proceeding  in the same  jurisdiction,  be liable  for the fees and
expenses of more than one separate  firm (in addition to any local  counsel) for
all Indemnified Persons, and that all such fees and expenses shall be reimbursed
as they are incurred. Any such separate firm (x) for any Initial Purchaser,  its
affiliates,  directors  and  officers  and any control  Persons of such  Initial
Purchaser shall be designated in writing by Barclays  Capital Inc. and JPMorgan,
(y) for any Holder,  its directors and officers and any control  Persons of such
Holder shall be  designated  in writing by the  Majority  Holders and (z) in all
other cases shall be  designated  in writing by the  Company.  The  Indemnifying
Person shall not be liable for any settlement of any proceeding effected without
its written  consent,  but if settled  with such  consent or if there be a final
judgment for the  plaintiff,  the  Indemnifying  Person agrees to indemnify each
Indemnified  Person  from and against  any loss or  liability  by reason of such
settlement or judgment.  Notwithstanding the foregoing sentence,  if at any time
an Indemnified Person 




                                       17



shall have  requested  that an  Indemnifying  Person  reimburse the  Indemnified
Person for fees and expenses of counsel as contemplated  by this paragraph,  the
Indemnifying  Person  shall  be  liable  for any  settlement  of any  proceeding
effected without its written consent if (i) such settlement is entered into more
than 30 days after receipt by the  Indemnifying  Person of such request and (ii)
the  Indemnifying  Person shall not have  reimbursed the  Indemnified  Person in
accordance  with  such  request  prior  to  the  date  of  such  settlement.  No
Indemnifying  Person  shall,  without  the  written  consent of the  Indemnified
Person, effect any settlement of any pending or threatened proceeding in respect
of  which  any   Indemnified   Person  is  or  could   have  been  a  party  and
indemnification  could have been sought  hereunder by such  Indemnified  Person,
unless such settlement (A) includes an unconditional release of such Indemnified
Person,  in form  and  substance  reasonably  satisfactory  to such  Indemnified
Person,  from all  liability  on  claims  that are the  subject  matter  of such
proceeding  and (B) does not include any  statement  as to or any  admission  of
fault,  culpability  or a  failure  to act by or on  behalf  of any  Indemnified
Person.

     (d) If the indemnification  provided for in Sections 5(a) and 5(b) above is
unavailable to an Indemnified  Person or  insufficient in respect of any losses,
claims,  damages or  liabilities  referred  to therein,  then each  Indemnifying
Person under such paragraph,  in lieu of indemnifying  such  Indemnified  Person
thereunder,  shall  contribute to the amount paid or payable by such Indemnified
Person as a result of such losses,  claims,  damages or liabilities  (i) in such
proportion as is  appropriate to reflect the relative  benefits  received by the
Company from the offering of the Notes and the Exchange  Notes, on the one hand,
and by the Holders from receiving Notes or Exchange Notes  registered  under the
Securities Act, on the other hand, or (ii) if the allocation  provided by clause
(i) is not permitted by applicable  law, in such proportion as is appropriate to
reflect not only the  relative  benefits  referred to in clause (i) but also the
relative  fault of the  Company on the one hand and the  Holders on the other in
connection  with the  statements  or  omissions  that  resulted in such  losses,
claims,  damages  or  liabilities,  as  well  as any  other  relevant  equitable
considerations.  The  relative  fault  of the  Company  on the one  hand and the
Holders on the other shall be  determined  by reference  to, among other things,
whether  the  untrue or  alleged  untrue  statement  of a  material  fact or the
omission or alleged  omission to state a material  fact  relates to  information
supplied  by the Company or by the Holders  and the  parties'  relative  intent,
knowledge,  access to  information  and  opportunity  to correct or prevent such
statement or omission.

     (e) The  Company  and the  Holders  agree  that it  would  not be just  and
equitable if contribution pursuant to this Section 5 were determined by pro rata
allocation  (even if the Holders were treated as one entity for such purpose) or
by any other method of  allocation  that does not take account of the  equitable
considerations  referred to in Section 5(d) above. The amount paid or payable by
an Indemnified Person as a result of the losses, claims, damages and liabilities
referred to in Section  5(d) above  shall be deemed to  include,  subject to the
limitations  set forth  above,  any  legal or other  expenses  incurred  by such


                                       18


Indemnified Person in connection with any such action or claim.  Notwithstanding
the  provisions  of this  Section 5, in no event  shall a Holder be  required to
contribute  any amount in excess of the amount by which the total price at which
the Notes or  Exchange  Notes  sold by such  Holder  exceeds  the  amount of any
damages that such Holder has  otherwise  been  required to pay by reason of such
untrue or alleged untrue  statement or omission or alleged  omission.  No Person
guilty of fraudulent  misrepresentation  (within the meaning of Section 11(f) of
the Securities  Act) shall be entitled to  contribution  from any Person who was
not guilty of such fraudulent misrepresentation.

     (f) The remedies provided for in this Section 5 are not exclusive and shall
not  limit  any  rights or  remedies  that may  otherwise  be  available  to any
Indemnified Person at law or in equity.

     (g) The indemnity and contribution  provisions  contained in this Section 5
shall  remain  operative  and in full  force and  effect  regardless  of (i) any
termination of this Agreement,  (ii) any  investigation  made by or on behalf of
the  Initial  Purchasers  or any Holder or any Person  controlling  any  Initial
Purchaser  or any Holder,  or by or on behalf of the Company or the  officers or
directors of or any Person  controlling the Company,  (iii) acceptance of any of
the Exchange  Notes and (iv) any sale of  Registrable  Notes pursuant to a Shelf
Registration Statement.

6. General.

     (a) No Inconsistent Agreements. The Company represents, warrants and agrees
that (i) the rights granted to the Holders  hereunder do not in any way conflict
with and are not  inconsistent  with the rights  granted  to the  holders of any
other outstanding securities issued by the Company under any other agreement and
(ii) the Company has not entered  into,  on or after the date of this  Agreement
will not enter into, any agreement that is inconsistent  with the rights granted
to the Holders of  Registrable  Notes in this  Agreement or otherwise  conflicts
with the provisions hereof.

                                       19


     (b) Amendments and Waivers. The provisions of this Agreement, including the
provisions of this sentence, may not be amended,  modified or supplemented,  and
waivers or consents to departures  from the  provisions  hereof may not be given
unless the Company  has  obtained  the written  consent of Holders of at least a
majority in aggregate  principal  amount of the  outstanding  Registrable  Notes
affected  by  such  amendment,  modification,  supplement,  waiver  or  consent;
provided that no amendment,  modification,  supplement, waiver or consent to any
departure  from the provisions of Section 5 hereof shall be effective as against
any Holder of Registrable  Notes unless  consented to in writing by such Holder.
Any amendments, modifications, supplements, waivers or consents pursuant to this
Section 6(b) shall be by a writing executed by each of the parties hereto.

     (c) Notices. All notices and other communications provided for or permitted
hereunder  shall be made in writing  by  hand-delivery,  registered  first-class
mail, telex,  telecopier,  or any overnight courier;  (i) if to a Holder, at the
most  current  address  given by such Holder to the Company by means of a notice
given in accordance  with the  provisions  of this Section  6(c),  which address
initially is, with respect to the Initial  Purchasers,  the address set forth in
the  Purchase  Agreement;  (ii) if to the Company,  initially  at the  Company's
address  set  forth in the  Purchase  Agreement  and  thereafter  at such  other
address,  notice of which is given in  accordance  with the  provisions  of this
Section 6(c); and (iii) to such other persons at their  respective  addresses as
provided in the Purchase Agreement and thereafter at such other address,  notice
of which is given in accordance  with the  provisions of this Section 6(c).  All
such notices and communications  shall be deemed to have been duly given: at the
time delivered by hand, if personally delivered;  five Business Days after being
deposited in the mail,  postage  prepaid,  if mailed;  when  answered  back,  if
telexed; when receipt is acknowledged,  if telecopied;  and on the next Business
Day if timely  delivered to an overnight  courier.  Copies of all such  notices,
demands or other  communications  shall be concurrently  delivered by the Person
giving the same to the Trustee, at the address specified in the Indenture.

     (d)  Successors and Assigns.  This Agreement  shall inure to the benefit of
and be binding  upon the  successors,  assigns  and  transferees  of each of the
parties,  including,  without  limitation  and  without  the need for an express
assignment,  subsequent Holders; provided that nothing herein shall be deemed to
permit any  assignment,  transfer or other  disposition of Registrable  Notes in
violation  of the  terms of the  Purchase  Agreement  or the  Indenture.  If any
transferee of any Holder shall acquire Registrable Notes in any manner,  whether
by operation of law or otherwise,  such Registrable  Notes shall be held subject
to all the terms of this Agreement,  and by taking and holding such  Registrable
Notes such Person shall be conclusively deemed to have agreed to be bound by and
to perform all of the terms and  provisions  of this  Agreement  and such Person
shall be entitled to receive the benefits  hereof.  The Initial  Purchasers  (in
their capacity as Initial  Purchasers)  shall have no liability or obligation to
the  Company  


                                       20


with  respect to any  failure by a Holder to comply  with,  or any breach by any
Holder of, any of the obligations of such Holder under this Agreement.

     (e)  Third  Party  Beneficiaries.  Each  Holder  shall  be  a  third  party
beneficiary to the agreements  made  hereunder  between the Company,  on the one
hand, and the Initial Purchasers, on the other hand, and shall have the right to
enforce  such  agreements  directly  to the  extent  it deems  such  enforcement
necessary  or  advisable  to protect  its rights or the rights of other  Holders
hereunder.

     (f)  Counterparts.  This  Agreement  may  be  executed  in  any  number  of
counterparts and by the parties hereto in separate  counterparts,  each of which
when so  executed  shall be  deemed  to be an  original  and all of which  taken
together shall constitute one and the same agreement.

     (g)  Headings.  The  headings  in this  Agreement  are for  convenience  of
reference  only,  are  not a part of this  Agreement  and  shall  not  limit  or
otherwise affect the meaning hereof.

     (h) Governing  Law. This  Agreement  shall be governed by, and construed in
accordance with, the laws of the State of New York.

     (i) Miscellaneous. This Agreement contains the entire agreement between the
parties relating to the subject matter hereof and supersedes all oral statements
and prior writings with respect  thereto.  If any term,  provision,  covenant or
restriction  contained  in  this  Agreement  is held  by a  court  of  competent
jurisdiction to be invalid,  void or unenforceable or against public policy, the
remainder of the terms, provisions,  covenants and restrictions contained herein
shall remain in full force and effect and shall in no way be affected,  impaired
or invalidated.  The Company and the Initial  Purchasers  shall endeavor in good
faith negotiations to replace the invalid, void or unenforceable provisions with
valid provisions the economic effect of which comes as close as possible to that
of the invalid, void or unenforceable provisions.


                                       21



     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date
first written above.
