Item 5.  Other Events.

Issuance of Senior Redeemable Discount Notes due 2007

     On September 17, 1997, Nextel Communications, Inc. ("Nextel") completed the
sale of $840 million principal amount at maturity of Senior Redeemable  Discount
Notes due 2007 (the  "Notes").  The issue  price of the Notes,  which  mature on
September  15,  2007,  was  $595.57  per  $1,000  principal  amount at  maturity
(generating   approximately   $500   million  in  aggregate   gross   proceeds),
representing  a yield to  maturity  of 10.65%  computed  on a  semi-annual  bond
equivalent basis from the date of issuance. Cash interest will not accrue on the
Notes prior to September 15, 2002.  Commencing September 15, 2002, cash interest
on the Notes will be payable on March 15 and September 15 of each year at a rate
of 10.65% per annum.  The Notes are  redeemable,  at the option of Nextel at any
time,  in  whole or in  part,  on or after  September  15,  2002,  at  specified
redemption prices plus accrued and unpaid interest. In addition, in the event of
one or more sales by Nextel prior to September 15, 2000 of at least $125 million
of its capital  stock, a portion of the Notes not to exceed a maximum of 33-1/3%
of the  aggregate  accreted  value of the  outstanding  Notes may be redeemed at
Nextel's  option  within  180 days  after  such sale from the net cash  proceeds
thereof at 110.65% of such accreted value to the date of  redemption.  The Notes
are  senior  unsecured  indebtedness  of Nextel  and rank pari passu in right of
payment with all  unsubordinated,  unsecured  indebtedness of Nextel,  including
indebtedness  evidenced by Nextel's five outstanding issues of Senior Redeemable
Discount  Notes,  and will be senior  in right of  payment  to all  subordinated
indebtedness of Nextel.

     The Notes were issued in a private placement  transaction and have not been
registered with the Securities and Exchange  Commission (the "Commission") under
the Securities Act of 1933 (the  "Securities  Act"),  and may not be sold absent
registration or an applicable exemption from the registration  requirements.  In
connection  with the  issuance  of the Notes,  Nextel has agreed to use its best
efforts to file with the Commission and cause to become effective a registration
statement  with respect to a registered  offer to exchange the then  outstanding
Notes  for  Notes of equal  value  that have  been  registered  pursuant  to the
Securities Act (the "Exchange  Offer").  In the event that the Exchange Offer is
not consummated prior to specified dates, additional incremental interest on the
accreted  value of the  Notes  will  accrue  until  the  Exchange  Offer is
consummated or certain other requirements are met.

     Terms of the  Notes  are set  forth in the  Indenture  attached  hereto  as
Exhibit 4.1, which is incorporated  herein by reference,  and the description of
the terms of the  Notes  included  herein  is  qualified  by  reference  to such
Indenture.

     Net cash proceeds from the sale of the Notes of approximately  $486 million
will be used by Nextel to implement its previously  disclosed business plan that
contemplates  an  accelerated  and expanded  deployment of its digital  wireless
communications  networks  in its  domestic  markets  during  1997  and  1998.

     In connection with the sale of the Notes, Nextel, Nextel Finance Company, a
wholly owned  subsidiary of Nextel ("NFC"),  and certain  subsidiaries of Nextel
entered into certain technical amendments to the agreements relating to Nextel's
existing bank and vendor financing  arrangements.  These amendments are filed as
Exhibits 4.2, 4.3 and 4.4 hereto.

SECTION 102. COMPLIANCE CERTIFICATES AND OPINIONS.

     Upon any  application  or request by the Company to the Trustee to take any
action under any provision of this  Indenture,  the Company shall furnish to the
Trustee  such  certificates  and  opinions  as may be  required  under the Trust
Indenture Act. Each such certificate or opinion shall be given in the form of an

covenant provided for in this Indenture shall include

     opinion has read such  covenant or  condition  and the  definitions  herein

SECTION 103. FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

COMAIN01 Doc: 129351_6.WPD
Printed: September 15, 1997 (3:13pm)       36             1997 Notes Indenture

<PAGE>

it is not  necessary  that all such matters be certified  by, or covered by
the opinion of, only one such Person, or that they be so certified or covered by
only one  document,  but one such  Person may  certify  or give an opinion  with
respect to some matters and one or more other such Persons as to other  matters,
and any such Person may certify or give an opinion as to such  matters in one or
several documents.

     Any  certificate  or opinion of an  officer  of the  Company  may be based,
insofar as it relates to legal  matters,  upon a  certificate  or opinion of, or
representations  by,  counsel,  unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or  representations
with respect to the matters upon which his  certificate  or opinion is based are
erroneous.  Any such certificate or opinion of counsel may be based,  insofar as
it  relates  to  factual   matters,   upon  a  certificate  or  opinion  of,  or
representations  by, an officer or  officers  of the  Company  stating  that the
information  with respect to such factual  matters is in the  possession  of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know,  that the certificate or opinion or  representations  with respect to such
matters are erroneous.

     Where  any  Person  is  required  to  make,  give  or  execute  two or more
applications,  requests, consents,  certificates,  statements, opinions or other
instruments  under this Indenture,  they may, but need not, be consolidated  and
form one instrument.

SECTION 104. ACTS OF HOLDERS; RECORD DATES

     Any request, demand,  authorization,  direction, notice, consent, waiver or
other action  provided or  permitted  by this  Indenture to be given or taken by
Holders  may  be  embodied  in and  evidenced  by one  or  more  instruments  of
substantially  similar  tenor  signed by such Holders in person or by agent duly
appointed in writing;  and, except as herein otherwise expressly provided,  such
action shall become  effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required,  to the Company. Such
instrument  or  instruments  (and the  action  embodied  therein  and  evidenced
thereby) are herein  sometimes  referred to as the "Act" of the Holders  signing
such instrument or instruments.  Proof of execution of any such instrument or of
a writing  appointing any such agent shall be sufficient for any purpose of this
Indenture

and (subject to Section 601)  conclusive  in favor of the Trustee and the
Company, if made in the manner provided in this Section.

     The fact and date of the execution by any Person of any such  instrument or
writing may be proved by the  affidavit  of a witness of such  execution or by a
certificate  of a notary  public  or  other  officer  authorized  by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a  signer  acting  in a  capacity  other  than  his  individual  capacity,  such
certificate  or  affidavit  shall  also  constitute   sufficient  proof  of  his
authority. The fact and date of the execution of any such instrument or writing,
or the  authority of the Person  executing  the same,  may also be proved in any
other manner which the Trustee deems sufficient.

     The ownership of Securities shall be proved by the Security Register.

     Any request, demand,  authorization,  direction, notice, consent, waiver or
other Act of the Holder of any Security  shall bind every  future  Holder of the
same Security and the Holder of every Security  issued upon the  registration of
transfer  thereof  or in  exchange  therefor  or in lieu  thereof  in respect of
anything  done,  omitted or suffered to be done by the Trustee or the Company in
reliance  thereon,  whether  or not  notation  of such  action is made upon such
Security.

     The Company may set any day as a record date for the purpose of determining
the Holders of  Outstanding  Securities  entitled  to give or take any  request,
demand,  authorization,  direction,  notice,  consent,  waiver  or other  action
provided  or  permitted  by this  Indenture  to be given or taken by  Holders of
Securities,  provided  that the Company  may not set a record date for,  and the
provisions  of this  paragraph  shall not apply with  respect  to, the giving or
making of any notice, declaration,  request or direction referred to in the next
paragraph. If any record date is set pursuant to this paragraph,  the Holders of
Outstanding  Securities  on such record  date,  and no other  Holders,  shall be
entitled to take the relevant action, whether or not such Holders remain Holders
after  such  record  date;  provided  that no such  action  shall  be  effective
hereunder unless taken on or prior to the applicable  Record  Expiration Date by
Holders of the  requisite  principal  amount of  Outstanding  Securities on such
record date; and provided,  further, that for the purpose of

COMAIN01 Doc: 129351_6.WPD

<PAGE>

determining  whether  Holders  of the  requisite  principal  amount of such
Securities  have taken such  action,  no  Security  shall be deemed to have been
Outstanding  on such record date unless it is also  Outstanding on the date such
action is to become  effective.  Nothing in this  paragraph  shall  prevent  the
Company  from  setting a new record  date for any action for which a record date
has previously  been set pursuant to this  paragraph  (whereupon the record date
previously set shall  automatically and with no action by any Person be canceled
and of no effect),  nor shall  anything in this paragraph be construed to render
ineffective  any action taken by Holders of the  requisite  principal  amount of
Outstanding  Securities  on the date such  action is taken.  Promptly  after any
record date is set pursuant to this paragraph,  the Company, at its own expense,
shall cause notice of such record date,  the proposed  action by Holders and the
applicable  Record  Expiration Date to be given to the Trustee in writing and to
each Holder of Securities in the manner set forth in Section 106.

     The Trustee may set any day as a record date for the purpose of determining
the Holders of Outstanding  Securities  entitled to join in the giving or making
of (i) any Notice of Default,  (ii) any declaration of acceleration  referred to
in  Section 502,  (iii) any  request to  institute  proceedings  referred  to in
Section 507(2) or (iv) any direction  referred to in Section 512.  If any record
date is set pursuant to this paragraph, the Holders of Outstanding Securities on
such  record  date,  and no other  Holders,  shall be  entitled  to join in such
notice,  declaration,  request or direction,  whether or not such Holders remain
Holders after such record date;  provided that no such action shall be effective
hereunder unless taken on or prior to the applicable  Record  Expiration Date by
Holders of the  requisite  principal  amount of  Outstanding  Securities on such
record date; and provided,  further, that for the purpose of determining whether
Holders of the requisite  principal  amount of such  Securities  have taken such
action, no Security shall be deemed to have been Outstanding on such record date
unless it is also  Outstanding  on the date such action is to become  effective.
Nothing in this paragraph shall be construed to prevent the Trustee from setting
a new record date for any action (whereupon the record date previously set shall
automatically  and  without  any  action  by any  Person be  canceled  and of no
effect), nor shall anything in this paragraph be construed to render ineffective
any action taken by Holders of the  requisite  principal  amount of  Outstanding
Securities on the date such action is taken.  Promptly  after any record date is
set pursuant to this paragraph,

COMAIN01 Doc: 129351_6.WPD

the Trustee,  at the Company's  expense,  shall cause notice of such record
date,  the  matter(s) to be submitted  for  potential  action by Holders and the
applicable  Record  Expiration Date to be given to the Company in writing and to
each Holder of Securities in the manner set forth in Section 106.

     With  respect to any record date set  pursuant to this  Section,  the party
hereto  that  sets  such  record  date  may  designate  any  day as the  "Record
Expiration Date" and from time to time may change the Record  Expiration Date to
any earlier or later day, provided that no such change shall be effective unless
notice of the  proposed new Record  Expiration  Date is given to the other party
hereto in writing,  and to each Holder of  Securities in the manner set forth in
Section  106, on or before the  existing  Record  Expiration  Date.  If a Record
Expiration  Date is not designated  with respect to any record date set pursuant
to this  Section,  the party hereto that set such record date shall be deemed to
have  initially  designated  the 180th day after such  record date as the Record
Expiration Date with respect thereto,  subject to its right to change the Record
Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no
Record  Expiration  Date shall be later than the 180th day after the  applicable
record date.

     Without  limiting the foregoing,  a Holder  entitled  hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal  amount of such Security or by one or more duly
appointed  agents  each of which may do so  pursuant  to such  appointment  with
regard to all or any part of such principal amount.

SECTION 105.  NOTICES, ETC., TO TRUSTEE AND COMPANY.

     Any request, demand,  authorization,  direction, notice, consent, waiver or
Act of Holders or other  document  provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,

          (1) the  Trustee by any Holder or by the Company  shall be  sufficient
     for every purpose hereunder if made,  given,  furnished or filed in writing
     and  mailed,  first-class  postage  prepaid,  to or with the Trustee at its
     Corporate Trust Office, Attention: Indenture Trust Division, or

<PAGE>

          (2) the  Company by the Trustee or by any Holder  shall be  sufficient
     for every purpose hereunder (unless otherwise herein expressly provided) if
     in  writing  and  mailed,  first-class  postage  prepaid,  to  the  Company
     addressed  to it at the address of its  principal  office  specified in the
     first  paragraph  of this  instrument  or at any other  address  previously
     furnished in writing to the Trustee by the Company.

SECTION 106. NOTICE TO HOLDERS; WAIVER.

     Where this  Indenture  provides  for  notice to Holders of any event,  such
notice shall be sufficiently given (unless otherwise herein expressly  provided)
if in writing and mailed,  first-class  postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register,  not later
than the latest date (if any),  and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders is
given by mail,  neither the failure to mail such  notice,  nor any defect in any
notice so mailed,  to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders.  Where this Indenture  provides for notice
in any manner,  such  notice may be waived in writing by the Person  entitled to
receive such notice,  either before or after the event, and such waiver shall be
the equivalent of such notice.  Waivers of notice by Holders shall be filed with
the Trustee,  but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

     In case by reason of the suspension of regular mail service or by reason of
any other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall  constitute
a sufficient notification for every purpose hereunder.

SECTION 107.  CONFLICT WITH TRUST INDENTURE ACT.

     If any provision hereof limits,  qualifies or conflicts with a provision of
the Trust Indenture Act that is required under such Act to be part of and govern
this Indenture,  the latter  provision  shall control.  If any provision of this
Indenture modifies or excludes any provision of the Trust

shall be deemed to apply to this Indenture as so modified or to be excluded,  as
the case may be.

     The Article and Section  headings  herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

its successors and assigns, whether so expressed or not.

SECTION 110. SEPARABILITY CLAUSE

     In case any  provision  in this  Indenture  or in the  Securities  shall be
invalid, illegal or unenforceable,  the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 111. BENEFITS OF INDENTURE

     Nothing in this Indenture or in the Securities,  express or implied,  shall
give to any Person, other than the parties hereto and their successors hereunder
and the  Holders of  Securities,  any benefit or any legal or  equitable  right,
remedy or claim under this Indenture.

SECTION 113. LEGAL HOLIDAYS.

     In any case where any Interest Payment Date, Redemption Date, Purchase Date
or  Stated  Maturity  of  any  Security  shall  not  be  a  Business  Day,  then
(notwithstanding  any other  provision of this  Indenture or of the  Securities)
payment of interest or principal (and premium,  if any) need not be made on such
date,  but may be made on the next  succeeding  Business Day with the same force

includes any successor Person under the Indenture  hereinafter referred to), for
value  received,  hereby  promises to pay to  __________________,  or registered
assigns,  the  principal sum of  _____________________  Dollars on September 15,
2007 and to pay interest thereon from September 15, 2002 or from the most recent
Interest  Payment  Date to which  interest has been paid or duly  provided  for,
semi-annually  in arrears on March 15 and September 15 in each year,  commencing
March 15, 2003 at the rate of 10.65% per annum,  until the  principal  hereof is
paid or duly provided for, provided that any principal and premium, and any such
installment  of interest,  which is overdue  shall bear  interest at the rate of
10.65%  per annum (to the extent  that the  payment  of such  interest  shall be
legally enforceable), from the dates such amounts are due until they are paid or
duly provided for, and such interest shall be payable on demand. The interest so
payable,  and punctually paid or duly provided for, on any Interest Payment Date

this Security (or one or more Predecessor  Securities) is registered at the
close of business on the Regular Record Date for such  interest,  which shall be
the March 1 or September 1 (whether or not a Business  Day), as the case may be,
next preceding  such Interest  Payment Date. Any such interest not so punctually
paid or duly  provided for will  forthwith  cease to be payable to the Holder on
such Regular Record Date and may either be paid to the Person in whose name this
Security (or one or more  Predecessor  Securities) is registered at the close of
business on a Special Record Date for the payment of such Defaulted  Interest to
be fixed by the Trustee,  notice whereof shall be given to Holders of Securities
not less than 10 days prior to such Special  Record Date, or be paid at any time
in any  other  lawful  manner  not  inconsistent  with the  requirements  of any
securities  exchange on which the Securities may be listed, and upon such notice
as may be  required  by  such  exchange,  all as  more  fully  provided  in said
Indenture.

     The  principal of this  Security  shall not bear or accrue  interest  until
September 15, 2002, except in the case of a default in payment of principal upon
acceleration,  redemption or repurchase and, in such case, the overdue principal

the extent that the payment of such interest shall be legally enforceable), from

Interest on any overdue  principal  or premium  shall be payable on demand.  Any
such interest on overdue  principal or premium which is not paid on demand shall
bear interest at the rate of 10.65% per annum (to the extent that the payment of
such interest on interest shall be legally  enforceable),  from the date of such
demand until the amount so demanded is paid or duly provided for, and such shall
be payable on demand.

     If an exchange offer registered under the Securities Act is not consummated
on or before  March 15, 1998 in  accordance  with the terms of the  Registration
Rights  Agreement,  interest  (in  addition  to the  accrual of  original  issue
discount  during the period  ending  September 15,  2002 and in  addition to the
interest otherwise due on the Securities after such date) will accrue from March
15,  1998,  at an  annual  rate of  0.5%  of  Accreted  Value  on the  preceding
Semiannual  Accrual Date on the  Securities  (and if such exchange  offer is not
consummated before June 15, 1998, an additional incremental interest amount will
accrue from June 15,  1998 at an annual  rate of 0.5% of  Accreted  Value on the

March 15 and September 15,  commencing  March 15, 1998, until the earlier of the
date upon which (i) the exchange offer is consummated, (ii) a Shelf Registration
Statement  with  respect  to all  Registerable  Securities  (as  defined  in the
Registration  Rights Agreement) is declared  effective,  or (iii) the Securities
become fully tradeable without  registration  under the Securities Act, provided
that upon the request of any Holder of the Securities,  the Company will deliver
to such Holder  certificates  evidencing  such Holder's  Securities  without the
Private  Placement  Legend.  The  Holder of this  Security  is  entitled  to the
benefits of such Registration Rights Agreement.

     Payment of the principal of (and premium,  if any) and any interest on this
Security will be made at the office or agency of the Company maintained for that
purpose  in the  Borough  of  Manhattan,  The City of New York,  in such coin or
currency  of the  United  States of  America  as at the time of payment is legal
tender for payment of public and private debts;  provided,  however, that at the
option of the  Company  payment of interest  may be made by check  mailed to the
address  of the Person  entitled  thereto as such  address  shall  appear in the
Security Register.

     Reference  is hereby made to the further  provisions  of this  Security set
forth on the reverse  hereof,  which further  provisions  shall for all purposes
have the same effect as if set forth at this place.

     This  Security  is one of a duly  authorized  issue  of  Securities  of the

meaning assigned to it in such instrument), between the Company and Harris Trust
and Savings Bank, as Trustee  (herein called the "Trustee",  which term includes

Indenture  for a statement  of the  respective  rights,  limitations  of rights,
duties and immunities  thereunder of the Company, the Trustee and the Holders of

     The Securities may be redeemed at any time on or after  September 15, 2002,
at the  Company's  option,  in whole or in part,  upon not less than 30 nor more
than 60 days' prior  written  notice mailed by first class mail to each holder's

accrued and unpaid  interest,  if any, to the Redemption  Date, if redeemed
during the 12-month period beginning September 15 of each of the years set forth
below.

             Year               Percentage
             2002               105.325%
             2003               102.663%

     On or after  September 15, 2004, the Company may redeem the Securities at a
Redemption Price equal to 100% of the principal amount thereof,  together in the
case of any such  redemption  with accrued  interest,  if any, to the Redemption
Date,  but interest  installments  whose Stated  Maturity is on or prior to such
Redemption  Date will be payable to the  Holders of such  Securities,  or one or
more Predecessor Securities,  of record at the close of business on the relevant
Record Dates referred to on the face hereof, all as provided in the Indenture.

     In addition to any  redemption  provided for in the  immediately  preceding
paragraphs,  in the event of the sale by the Company  after the Closing Date and
prior to September 15, 2000 of its Capital Stock (other than  Redeemable  Stock)
in a single  transaction  or series of  transactions  for an aggregate  purchase
price  equal to or  exceeding  $125  million,  up to a maximum of 33 1/3% of the
aggregate Accreted Value of the Outstanding  Securities will, within 180 days of
such sale, at the option of the Company,  upon not less than 30 nor more than 60
days' notice by mail, be redeemable  from the net proceeds  thereof (but only to
the extent such proceeds consist of cash or readily  marketable cash equivalents
received in respect of the Company's  Capital Stock so sold, in each case net of
all  commissions,  discounts,  fees,  expenses  and taxes  incurred  in  respect
thereof) at a  Redemption  Price equal to 110.65% of the  Accreted  Value of the
Securities to be redeemed to the Redemption Date.

     For purposes of this  Security  and the  Indenture,  Accreted  Value of any
Outstanding Security as of or to any date of determination means an amount equal
to the sum of (i) the  issue price of such  Security as determined in accordance
with  Section 1273  of the Code plus  (ii) the  aggregate of the portions of the
original  issue  discount  (the excess of the amounts  considered as part of the
"stated  redemption  price at maturity" of such  Security  within the meaning of
Section 1273(a)(2) of the Code or any successor provisions,  whether denominated
as  principal  or interest,  over the issue price of such  Security)

that shall  theretofore  have accrued  pursuant to Section 1272 of the Code
(without  regard to  Section  1272(a)(7)  of the Code) from the date of issue of
such  Security  (a) for  each  six-month  or shorter  period  ending March 15 or
September 15 prior to the date of determination  and (b) for the shorter period,
if any, from the end of the immediately  preceding  six-month or shorter period,
as the case may be, to the date of determination,  plus (iii) accrued and unpaid
interest to the date such  Accreted  Value is paid (without  duplication  of any
amount set forth in (ii) above),  minus all amounts  theretofore paid in respect
of such Security, which amounts are considered as part of the "stated redemption
price at maturity" of such Security within the meaning of Section  1273(a)(2) of
the Code or any successor provisions (whether such amounts paid were denominated
principal or interest).

     The Securities do not have the benefit of any sinking fund obligations.

     In the event of redemption,  or purchase  pursuant to an Offer to Purchase,
of this Security in part only, a new Security or Securities  for the  unredeemed
or  unpurchased  portion  hereof will be issued in the name of the Holder hereof
upon the cancellation hereof.

     The Indenture contains  provisions for defeasance at any time of the entire
indebtedness  of this  Security or certain  restrictive  covenants and Events of
Default with respect to this Security, in each case upon compliance with certain
conditions set forth in the Indenture.

     If an Event of Default shall occur and be continuing, there may be declared
due and payable the Default Amount of the Securities, in the manner and with the
effect  provided in the  Indenture.  Prior to September  15,  2002,  the Default
Amount in respect of this  Security  as of any  particular  date shall equal the
Accreted  Value of this  Security as of such date.  On and after  September  15,
2002, the Default  Amount in respect of this Security as of any particular  date
shall equal 100% of the principal  amount payable in respect of this Security at
the Stated Maturity  hereof.  Upon payment of (i) the Default Amount so declared
due and  payable  and any  overdue  installment  of  interest in respect of this
Security,  (ii) any  overdue  principal  or  premium  payable on  redemption  or
repurchase  of this  Security  and (iii) as  provided  on the face  hereof,  any
interest  on any

Security  (to the  extent  that the  payment of such  interest  shall be legally
enforceable),  all of the Company's obligations in respect of the payment of the
principal of and any premium and interest on this Security shall terminate.

     The Indenture provides that, subject to certain conditions,  if a Change of
Control  occurs,  the Company shall be required to make an Offer to Purchase for
all of the Securities.

     Unless the context otherwise  requires,  references herein to the principal
amount of any  Security  mean,  as of any day,  (i) with  respect to any portion
thereof  required  hereunder to be redeemed or  repurchased on any redemption or
repurchase  date on or prior to such day,  the amount due and payable in respect
of such portion upon such redemption or repurchase  date (excluding  premium and
interest),  (ii) with  respect to any  portion  thereof  not  required  to be so
redeemed or  repurchased,  but which has been  declared due and payable prior to
the Stated Maturity thereof as provided in the Indenture,  the Default Amount in
respect of such  portion as of such day and (iii)  with  respect to any  portion
thereof not  required so to be redeemed or  repurchased  and not so declared due
and payable,  such portion of the principal  amount of such Security  payable at
Stated Maturity thereof.

     The Indenture  permits,  with certain  exceptions as therein provided,  the
amendment  thereof and the  modification  of the rights and  obligations  of the
Company and the rights of the Holders of the  Securities  under the Indenture at
any time by the  Company  and the  Trustee  with the consent of the Holders of a
majority in aggregate  principal  amount at Stated Maturity of the Securities at
the time  Outstanding.  The Indenture  also contains  provisions  permitting the
Holders  of  specified  percentages  in  aggregate  principal  amount  at Stated
Maturity of the Securities at the time Outstanding,  on behalf of the Holders of
all the Securities,  to waive compliance by the Company with certain  provisions
of the  Indenture  and  certain  past  defaults  under the  Indenture  and their
consequences. Any such consent or waiver by the Holder of this Security shall be
conclusive  and  binding  upon such  Holder and upon all future  Holders of this
Security and of any Security issued upon the  registration of transfer hereof or
in exchange  herefor or in lieu hereof,  whether or not notation of such consent
or waiver is made upon this Security.

Stated Maturity of Securities at the time  Outstanding a direction  inconsistent
with such request,  and shall have failed to institute any such proceeding,  for
60 days after  receipt  of such  notice,  request  and offer of  indemnity.  The
foregoing shall not apply to certain suits described in the Indenture, including

Date.)

     The Securities  shall be issuable only in registered  form without  coupons
and only in denominations  of $1,000 principal amount and any integral  multiple
thereof.

SECTION 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

     The  Securities  shall be executed on behalf of the Company by its Chairman
of the Board, its President or one of its Vice  Presidents,  under its corporate
seal  reproduced  thereon  attested  by its  Secretary  or one of its  Assistant
Secretaries.  The signature of any of these  officers on the  Securities  may be
manual or facsimile.

     Securities  bearing the manual or facsimile  signatures of individuals  who
were at any time the proper  officers  of the  Company  shall bind the  Company,
notwithstanding  that such  individuals  or any of them have ceased to hold such
offices prior to the  authentication  and delivery of such Securities or did not
hold such offices at the date of such Securities.

     At any time and from time to time after the  execution and delivery of this
Indenture,  the Company may  deliver  Securities  executed by the Company to the
Trustee for authentication, together with a Company Order for the authentication
and delivery of such Securities; and the Trustee in accordance with such Company
Order  shall  authenticate  and deliver  such  Securities  as in this  Indenture
provided and not otherwise.

     Each Security shall be dated the date of its authentication.

     No Security  shall be entitled to any benefit  under this  Indenture  or be
valid or  obligatory  for any purpose  unless there  appears on such  Security a
certificate  of  authentication  substantially  in the form  provided for herein
executed  by the  Trustee by manual  signature,  and such  certificate  upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder.

SECTION 304. TEMPORARY SECURITIES.

     Pending the preparation of definitive Securities,  the Company may execute,
and upon Company Order the Trustee  shall  authenticate  and deliver,  temporary
Securities  which  are  printed,  lithographed,   typewritten,  mimeographed  or
otherwise produced, in any authorized  denomination,  substantially of the tenor
of the  definitive  Securities  in lieu of which  they are  issued and with such
appropriate  insertions,  omissions,  substitutions  and other variations as the
officers  executing  such  Securities  may  determine,  as  evidenced  by  their
execution of such Securities.

     If  temporary  Securities  are issued,  the Company  will cause  definitive
Securities to be prepared without  unreasonable  delay. After the preparation of
definitive  Securities,  the  temporary  Securities  shall be  exchangeable  for
definitive  Securities upon surrender of the temporary  Securities at any office
or agency of the Company designated  pursuant to Section 1002, without charge to
the  Holder.  Upon  surrender  for  cancellation  of any one or  more  temporary
Securities  the Company  shall execute and the Trustee  shall  authenticate  and
deliver in exchange therefor a like principal amount of definitive Securities of
authorized  denominations and of a like tenor.  Until so exchanged the temporary
Securities  shall in all  respects be entitled to the same  benefits  under this
Indenture as definitive Securities.

SECTION 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

     The Company  shall cause to be kept at the  Corporate  Trust  Office of the
Trustee a register  (the  register  maintained  in such  office and in any other
office or agency  designated  pursuant to Section  1002 being  herein  sometimes
collectively  referred to as the "Security  Register") in which, subject to such
reasonable  regulations as it may  prescribe,  the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby
appointed  "Security  Registrar" for the purpose of  registering  Securities and
transfers of Securities as herein provided.

     Upon surrender for registration of transfer of any Security at an office or
agency of the Company designated pursuant to Section 1002 for such purpose,  the
Company shall

execute, and the Trustee shall authenticate and deliver, in the name of the
designated  transferee  or  transferees,  one  or  more  new  Securities  of any
authorized  denominations and of a like aggregate principal amount and tenor. No
such transfer shall be effected until,  and such transferee shall succeed to the
rights of a Holder only upon,  final acceptance and registration of the transfer
by the Security Registrar in the Security Register. Prior to the registration of
any transfer by a Holder as provided  herein,  the Company,  the Trustee and any
agent of the  Company  shall  treat the  person in whose  name the  Security  is
registered  as the owner  thereof for all  purposes  whether or not the Security
shall be overdue, and neither the Company, the Trustee, nor any such agent shall
be  affected  by notice to the  contrary.  Furthermore,  any  Holder of a Global
Security shall, by acceptance of such Global  Security,  agree that transfers of
beneficial interests in such Global Security may be effected only through a book
entry system maintained by the Holder of such Global Security (or its agent) and
that ownership of a beneficial  interest in the Security shall be required to be
reflected in a book entry.

     At the  option  of  the  Holder,  Securities  may be  exchanged  for  other
Securities  (including an exchange of securities for Exchange Securities) of any
authorized  denominations  and of a like aggregate  principal  amount and tenor,
upon  surrender  of the  Securities  to be  exchanged  at such  office or agency
provided,  that no exchange of Securities  for Exchange  Securities  shall occur
until a  Registration  Statement  shall  have  been  declared  effective  by the
Commission  and that  Securities  that are  exchanged  for  Exchange  Securities
pursuant  to such  Registration  Statement  shall be  canceled  by the  Trustee.
Whenever any  Securities  are so  surrendered  for  exchange,  the Company shall
execute,  and the Trustee shall  authenticate and deliver,  the Securities which
the Holder making the exchange is entitled to receive.

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

     Every Security presented or surrendered for registration of transfer or for
exchange  shall (if so required by the Company or the Trustee) be duly endorsed,
or be accompanied

by a written instrument of transfer in form satisfactory to the Company and
the Security Registrar duly executed, by the Holder thereof or his attorney duly
authorized in writing.

     No  service  charge  shall  be made for any  registration  of  transfer  or
exchange of Securities,  but the Company may require payment of a sum sufficient
to cover any tax or other governmental  charge that may be imposed in connection
with any  registration  of  transfer  or  exchange  of  Securities,  other  than
exchanges  pursuant to Section 304, 906 or 1108 or in accordance  with any Offer
to Purchase  pursuant to  Section 1013,  and in any such case not  involving any
transfer.

     The Company shall not be required (i) to issue, register the transfer of or
exchange  any Security  during a period  beginning at the opening of business 15
days  before the day of the  mailing  of a notice of  redemption  of  Securities
selected for  redemption  under Section 1104 and ending at the close of business
on the day of such mailing,  or (ii) to register the transfer of or exchange any
Security so selected for  redemption in whole or in part,  except the unredeemed
portion of any Security being redeemed in part.

SECTION 306. BOOK-ENTRY PROVISIONS FOR GLOBAL SECURITY.

     (a) The Global  Security  initially  shall (i) be registered in the name of
the Depository for such Global Security or the nominee of such Depository;  (ii)
be  delivered to the Trustee as custodian  for such  Depository;  and (iii) bear
legends as set forth in Section 205.

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

     (b)  Transfers of a Global  Security  shall be limited to transfers of such
Global Security in whole, but not in part, to the Depository,  its successors or
their respective  nominees.  Interests of beneficial owners in a Global Security
may be transferred in accordance with the rules and procedures of the Depository
and the  provisions of Section 307. In addition,  Physical  Securities  shall be
transferred to all beneficial owners in exchange for their beneficial  interests
in the Global Security, respectively, if (i) the Depository notifies the Company
that it is  unwilling  or  unable  to  continue  as  Depository  for the  Global
Security, as the case may be, and a successor depository is not appointed by the
Company within 90 days of such notice, (ii) an Event of Default has occurred and
is continuing  and the Security  Registrar has received a request  therefor from
the  Depository  or (iii) in  accordance  with the rules and  procedures  of the
Depository and the provisions of Section 307.

     (c) In  connection  with  any  transfer  of a  portion  of  the  beneficial
interests in the Global Security to beneficial  owners pursuant to paragraph (b)
of this Section,  the Security  Registrar shall reflect on the Security Register
the date and a decrease  in the  principal  amount of the Global  Security in an
amount equal to the principal  amount of the  beneficial  interest in the Global
Security to be transferred, and the Company shall execute, and the Trustee shall
authenticate  and deliver,  one or more  Physical  Securities  of like tenor and
amount.

     (d) In  connection  with the  transfer  of the entire  Global  Security  to
beneficial owners pursuant to paragraph (b) of this Section, the Global Security
shall be deemed to be  surrendered  to the  Trustee  for  cancellation,  and the
Company shall execute,  and the Trustee shall authenticate and deliver,  to each
beneficial  owner  identified by the  Depository in exchange for its  beneficial
interest in the Global Security, an equal aggregate principal amount of Physical
Securities of authorized denominations.

     (e) Any  Physical  Security  delivered  in exchange  for an interest in the
Global  Security  pursuant to paragraph  (b), (c) or (d) of this Section  shall,
except as  otherwise  provided by  paragraph  (d) of Section 307 bear the legend
regarding transfer restrictions  applicable to the Physical Securities set forth
in Section 205.

     (f) The  registered  holder  of a Global  Security  may grant  proxies  and
otherwise  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 Securities.

SECTION 307. SPECIAL TRANSFER PROVISIONS.

     Unless and until a Security is exchanged  for an Exchange  Security or sold
in connection with an effective  Shelf  Registration  Statement  pursuant to the
Registration Rights Agreement, the following provisions shall apply:

          (a)  Transfers  to QIBs.  The  following  provisions  shall apply with
     respect to the registration of any proposed transfer of a Physical Security
     or  an  interest  in  the  Global  Security  to a QIB  (excluding  Non-U.S.
     Persons):

               (i) If the  Security to be  transferred  consists of (x) Physical
          Securities, the Security Registrar shall register the transfer if such
          transfer  is being made by a proposed  transferor  who has checked the
          box provided  for on the form of security  stating,  or has  otherwise
          advised the Company and the Security  Registrar  in writing,  that the
          sale has been made in compliance  with the provisions of Rule 144A, to
          a transferee who has signed the certification provided for on the form
          of  Security  stating,  or has  otherwise  advised the Company and the
          Security Registrar in writing,  that it is purchasing the Security for
          its own account or an account with respect to which it exercises  sole
          investment discretion and that it and any such account is a QIB within
          the  meaning of Rule  144A,  and is aware that the sale to it is being
          made in reliance on Rule 144A and  acknowledges  that it has  received
          such information regarding the Company as it has requested pursuant to
          Rule 144A or has determined not to request such  information  and that
          it is  aware  that  the  transferor  is  relying  upon  its  foregoing
          representations  in order to claim  the  exemption  from  registration
          provided by Rule 144A or (y) an interest in the Global  Security,  the
          transfer of such  interest may be effected only through the book entry
          system maintained by the Depository.

               (ii) If the  proposed  transferee  is an  Agent  Member,  and the
          Security  to be  transferred  consists of  Physical  Securities,  upon
          receipt by the Security Registrar of the

          accordance  with  the  Depository's   and  the  Security   Registrar's
          procedures,  the  Security  Registrar  shall  reflect in the  Security
          Register the date and an increase in the principal  amount at maturity
          of the Global  Security in an amount equal to the principal  amount at
          maturity of the Physical Securities to be transferred, and the Trustee

          (b) Transfers of Interests in Unlegended Offshore Physical Securities.
     The  following  provisions  shall  apply with  respect to any  transfer  of

     requiring any additional certification.

          (c)  Transfers  to  Non-U.S.   Persons  at  Any  Time.  The  following
     provisions  shall  apply with  respect to any  transfer  of a Security to a
     Non-U.S. Person:

               (i) Prior to October  28,  1997,  the  Security  Registrar  shall
          register any proposed transfer of a Security to a Non-U.S. Person upon
          receipt of a certificate substantially in the form of Exhibit A hereto
          from the proposed transferor.

               (ii) On and after October 28, 1997, the Security  Registrar shall
          register any proposed transfer to any Non-U.S.  Person if the Security
          to be transferred is a Physical  Security or an interest in the Global

          (d)  Private  Placement  Legend.   Upon  the  transfer,   exchange  or
     replacement of Securities  not bearing the Private  Placement  Legend,  the
     Security  Registrar  shall deliver  Securities that do not bear the Private
     Placement Legend. Upon the transfer,  exchange or replacement of securities
     bearing the Private Placement Legend,  the Security Registrar shall deliver
     only  Securities that bear the Private  Placement  Legend unless either (i)
     the circumstances  contemplated by paragraphs  (a)(i)(x) or (d)(ii) of this
     Section 307 exist or (ii) there is  delivered  to the Trustee an Opinion of
     Counsel  reasonably  satisfactory  to the  Company  and the  Trustee 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.

          (e) General.  By its  acceptance  of any Security  bearing the Private
     Placement  Legend,  each  Holder  of  such  a  Security   acknowledges  the
     restrictions  on transfer of such Security set forth in this  Indenture and
     in the  Private  Placement  Legend and agrees  that it will  transfer  such
     Security only as provided in this Indenture.  The Security  Registrar shall
     not register a transfer of any Security unless such transfer  complies with
     the  restrictions  on  transfer of such  Security  set forth in the Private
     Placement Legend and in this Indenture.  In connection with any transfer of
     Securities,  each Holder  agrees by its  acceptance  of the  Securities  to
     furnish the Trustee or the Company such  certifications,  legal opinions or
     other information as either of them may reasonably  require to confirm that
     such transfer is being made pursuant to an exemption from, or a transaction
     not  subject  to, the  registration  requirements  of the  Securities  Act;
     provided that the Trustee shall not be required to determine  (but may rely
     on a determination  made by the Company with respect to) the sufficiency of
     any such certifications, legal opinions or other information.

          The Trustee  shall  retain  copies of all  letters,  notices and other
     written  communications  received  pursuant to Section 306 or this  Section
     307.  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 Trustee.

SECTION 308. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

     If any mutilated Security is surrendered to the Trustee,  the Company shall
execute and the Trustee shall  authenticate  and deliver in exchange  therefor a
new  Security  of like  tenor and  principal  amount  and  bearing a number  not
contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee  (i) evidence to
their  satisfaction  of the  destruction,  loss or  theft  of any  Security  and
(ii) such  security or indemnity as may be required by them to save each of them
and any agent of either of them harmless,  then, in the absence of notice to the
Company or the  Trustee  that such  Security  has been  acquired  by a bona fide
purchaser,  the Company  shall  execute  and upon its request the Trustee  shall
authenticate  and  deliver,  in  lieu of any  such  destroyed,  lost  or  stolen
Security, a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

     In case any such mutilated,  destroyed,  lost or stolen Security has become
or is about to become  due and  payable,  the  Company  in its  discretion  may,
instead of issuing a new Security, pay such Security.

     Upon the issuance of any new Security  under this Section,  the Company may
require the payment of a sum  sufficient to cover any tax or other  governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

     Every  new  Security  issued  pursuant  to  this  Section  in  lieu  of any
destroyed,  lost or stolen  Security  shall  constitute  an original  additional
contractual  obligation of the Company,  whether or not the  destroyed,  lost or
stolen  Security  shall be at any  time  enforceable  by  anyone,  and  shall be
entitled to all the benefits of this Indenture equally and proportionately  with
any and all other Securities duly issued hereunder.

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

SECTION 309. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

     Interest on any Security which is payable,  and is punctually  paid or duly
provided for, on any Interest  Payment Date shall be paid to the Person in whose
name that Security (or one or more Predecessor  Securities) is registered at the
close of business on the Regular Record Date for such interest.

     Any interest on any Security which is payable,  but is not punctually  paid
or duly provided  for, on any Interest  Payment Date (herein  called  "Defaulted
Interest")  shall  forthwith  cease to be payable to the Holder on the  relevant
Regular  Record Date by virtue of having been such  Holder,  and such  Defaulted
Interest may be paid by the Company,  at its election in each case,  as provided
in Clause (1) or (2) below:

          (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Securities (or their respective  Predecessor
     Securities)  are  registered  at the close of business on a Special  Record
     Date for the payment of such  Defaulted  Interest,  which shall be fixed in
     the  following  manner.  The Company shall notify the Trustee in writing of
     the amount of Defaulted  Interest  proposed to be paid on each Security 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 deposited to be held in trust for
     the benefit of the Persons  entitled to such Defaulted  Interest as in this
     Clause provided.  Thereupon the Trustee shall fix a Special Record Date for
     the payment of such Defaulted Interest which shall be not more than 15 days
     and not less than 10 days prior to the date of the proposed payment and not
     less than 10 days  after the  receipt  by the  Trustee of the notice of the
     proposed  payment.  The Trustee shall  promptly  notify the Company of such
     Special  Record Date and,  in the name and at the  expense of the  Company,
     shall cause notice of the proposed  payment of such Defaulted  Interest and
     the Special  Record Date  therefor to be given to each Holder in the manner
     specified  in  Section  106,  not less than 10 days  prior to such  Special
     Record Date. Notice of the proposed payment of such Defaulted  Interest and
     the Special Record Date therefor having been so

     mailed,  such Defaulted Interest shall be paid to the Persons in whose
     names the  Securities  (or their  respective  Predecessor  Securities)  are
     registered  at the close of business on such Special  Record Date and shall
     no longer be payable pursuant to the following Clause (2).

          (2) The  Company  may make  payment of any  Defaulted  Interest in any
     other  lawful  manner  not  inconsistent   with  the  requirements  of  any
     securities  exchange on which the Securities  may be listed,  and upon such
     notice as may be required by such  exchange,  if, after notice given by the
     Company to the Trustee of the  proposed  payment  pursuant to this  Clause,
     such manner of payment shall be deemed practicable by the Trustee.

     Subject  to  the  foregoing  provisions  of  this  Section,  each  Security
delivered  under this Indenture upon  registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest  accrued
and unpaid, and to accrue, which were carried by such other Security.


SECTION 310. PERSONS DEEMED OWNERS.

     Prior to due presentment of a Security for  registration  of transfer,  the
Company,  the  Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such  Security is  registered as the owner of such Security
for the purpose of receiving  payment of principal of (and premium,  if any) and
(subject to  Section 309)  interest on such Security and for all other  purposes
whatsoever,  whether or not such  Security be overdue,  and neither the Company,
the Trustee  nor any agent of the  Company or the  Trustee  shall be affected by
notice to the contrary.

SECTION 311. CANCELLATION.

     All  Securities  surrendered  for  payment,  redemption,   registration  of
transfer  or exchange  or for credit  against any Offer to Purchase  pursuant to
Section 1013 shall,  if  surrendered  to any Person  other than the Trustee,  be
delivered  to the Trustee and shall be promptly  canceled by it. The Company may
at any time deliver to the Trustee for  cancellation  any Securities  previously
authenticated and delivered hereunder which the

notice may state that no  representation  is made as to the  correctness of such
numbers  either as printed on the  Securities or as contained in any notice of a
redemption  or  repurchase  and that  reliance  may be placed  only on the other
identification  numbers  printed on the  Securities,  and any such redemption or
repurchase shall not be affected by any defect in or omission of such numbers.

SECTION 502. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

     If an Event  of  Default  (other  than an Event  of  Default  specified  in
Section 501(8) or (9)) occurs and is continuing, then and in every such case the
Trustee  or the  Holders  of not less  than 25% in  principal  amount  at Stated
Maturity of the Outstanding Securities may declare the Default Amount of all the
Securities  to be due and  payable  immediately,  by a notice in  writing to the
Company (and to the Trustee if given by Holders),  and upon any such declaration
such Default Amount and any accrued  interest shall become  immediately  due and
payable.  If an Event of Default specified in Section 501(8) or (9) occurs,  the
Default Amount of and any accrued  interest on the Securities  then  Outstanding
shall ipso facto become  immediately  due and payable without any declaration or
other Act on the part of the Trustee or any Holder.

     Prior to  September  15,  2002,  the  "Default  Amount"  in  respect of any
particular  Security as of any particular date shall equal the Accreted Value of
the  Security as of such date.  On and after  September  15,  2002,  the Default
Amount in respect of any  particular  Security as of any  particular  date shall
equal 100% of the  principal  amount  payable in respect of the  Security at the
Stated Maturity thereof.

     At any time  after such a  declaration  of  acceleration  has been made and
before a judgment  or decree for  payment of the money due has been  obtained by
the Trustee as hereinafter in this Article  provided,  the Holders of a majority
in principal amount at Stated Maturity of the Outstanding Securities, by written
notice to the Company and the  Trustee,  may rescind and annul such  declaration
and its consequences if

          (1)  the  Company  has  paid  or  deposited  with  the  Trustee  a sum
     sufficient to pay

               (A) all overdue interest on all Securities  (without  duplication
          of any amount thereof paid or deposited  pursuant to Clause (B) or (C)
          below),

               (B) the  principal of (and  premium,  if any, on) any  Securities
          which  have  become  due  otherwise   than  by  such   declaration  of
          acceleration (including any Securities required to have been purchased
          on the  Purchase  Date  pursuant to an Offer to  Purchase  made by the
          Company)  and, to the extent that payment of such  interest is lawful,
          interest  thereon  at the rate  provided  by the  Securities  (without
          duplication of any amount thereof paid or deposited pursuant to Clause
          (A) above or Clause (C) below),

               (C) to the  extent  that  payment  of such  interest  is  lawful,
          interest upon overdue  interest at the rate provided by the Securities
          (without  duplication of any amount thereof paid or deposited pursuant
          to Clause (A) or (B) above), and

               (D) all sums paid or advanced by the  Trustee  hereunder  and the
          reasonable compensation,  expenses,  disbursements and advances of the
          Trustee, its agents and counsel;

          and

          (2) all Events of Default, other than the non-payment of the principal
     of  Securities  which  have  become  due  solely  by  such  declaration  of
     acceleration, have been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

     Unless the context otherwise requires,  references in this Indenture to the
principal  amount of any Security mean, as of any day,  (i) with  respect to any
portion  thereof  required  thereunder  to be  redeemed  or  repurchased  on any
redemption  or  repurchase  date on or prior to such  day,  the  amount  due and
payable in respect of such  portion  upon such  redemption  or  repurchase  date
(excluding  premium and interest),  (ii) with respect to any portion thereof not
required to be so redeemed or  repurchased,  but which has been declared due and
payable prior to the Stated Maturity  thereof,  the Default Amount in respect of
such  portion as of such day and (iii) with  respect to any portion  thereof not
required so to be redeemed or repurchased and not so

declared due and payable, such portion of the principal amount of such Security
payable at Stated Maturity thereof.


SECTION 503. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

     The Company covenants that if

          (1)  default is made in the payment of any  interest  on any  Security
     when such interest becomes due and payable and such default continues for a
     period of 30 days, or

          (2) default is made in the payment of the principal of (or premium, if
     any,  on) any  Security at the  Maturity  thereof  or, with  respect to any
     Security  required to have been purchased  pursuant to an Offer to Purchase
     made by the Company, at the Purchase Date thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of
the Holders of such  Securities,  the whole  amount then due and payable on such
Securities for principal (and premium, if any) and interest,  and, to the extent
that  payment of such  interest  shall be legally  enforceable,  interest on any
overdue principal (and premium, if any) and on any overdue interest, at the rate
provided by the  Securities,  and, in addition  thereto,  such further amount as
shall be sufficient to cover the costs and expenses of collection, including the
reasonable  compensation,  expenses,  disbursements and advances of the Trustee,
its agents and counsel.

     If an Event of Default  occurs and is  continuing,  the  Trustee may in its
discretion  proceed  to  protect  and  enforce  its rights and the rights of the
Holders by such appropriate  judicial proceedings as the Trustee shall deem most
effectual  to protect  and  enforce any such  rights,  whether for the  specific
enforcement  of any  covenant or  agreement  in this  Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.


SECTION 504. TRUSTEE MAY FILE PROOFS OF CLAIM.

obligor upon the Securities), its property

or  its  creditors,  the  Trustee  shall  be  entitled  and  empowered,  by
intervention  in such  proceeding  or  otherwise,  to take  any and all  actions
authorized  under the Trust Indenture Act in order to have claims of the Holders
and the Trustee allowed in any such proceeding. In particular, the Trustee shall
be  authorized  to collect and receive any moneys or other  property  payable or
deliverable  on any such claims and to distribute  the same;  and any custodian,
receiver, assignee, trustee, liquidator,  sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee  shall consent to the
making of such  payments  directly  to the  Holders,  to pay to the  Trustee any
amount  due it for the  reasonable  compensation,  expenses,  disbursements  and
advances of the Trustee,  its agents and counsel,  and any other amounts due the
Trustee under Section 607.

     No provision of this Indenture  shall be deemed to authorize the Trustee to
authorize  or  consent to or accept or adopt on behalf of any Holder any plan of
reorganization,  arrangement, adjustment or composition affecting the Securities
or the  rights of any  Holder  thereof or to  authorize  the  Trustee to vote in
respect of the claim of any Holder in any such  proceeding;  provided,  however,
that the  Trustee  may,  on behalf of the  Holders,  vote for the  election of a
trustee in  bankruptcy  or similar  official and be a member of a creditors'  or
other similar committee.


SECTION 505. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

     All rights of action and claims under this  Indenture or the Securities may
be prosecuted  and enforced by the Trustee  without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any
such  proceeding  instituted  by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the  reasonable  compensation,  expenses,  disbursements  and
advances of the Trustee,  its agents and counsel,  be for the ratable benefit of
the  Holders  of the  Securities  in respect  of which  such  judgment  has been
recovered.

SECTION 506. APPLICATION OF MONEY COLLECTED.

     Any money  collected  by the  Trustee  pursuant  to this  Article  shall be
applied in the following  order,  at the date or dates fixed by the Trustee and,
in case of the  distribution  of such money on account of principal (or premium,
if any) or  interest,  upon  presentation  of the  Securities  and the  notation
thereon of the  payment if only  partially  paid and upon  surrender  thereof if
fully paid:

          FIRST:  To the payment of all amounts  due the Trustee  under  Section
     607; and

          SECOND:  To the  payment  of the  amounts  then  due  and  unpaid  for

     amounts due and payable on such  Securities for principal (and premium,  if
     any) and interest, respectively.

SECTION 507. LIMITATION ON SUITS.

     No Holder of any Security shall have any right to institute any proceeding,
judicial or otherwise, with respect to this Indenture, or for the appointment of
a receiver or trustee, or for any other remedy hereunder, unless

          (1) such Holder has previously  given written notice to the Trustee of
     a continuing Event of Default;

          (2) the  Holders  of not less than 25% in  principal  amount at Stated
     Maturity of the Outstanding  Securities  shall have made written request to
     the Trustee to institute proceedings in respect of such Event of Default in
     its own name as Trustee hereunder;

          (3) such  Holder or Holders  have  offered to the  Trustee  reasonable
     indemnity  against the costs,  expenses and  liabilities  to be incurred in
     compliance with such request;

          (4) the Trustee for 60 days after its receipt of such notice,  request
     and offer of indemnity has failed to institute any such proceeding; and

it being understood and intended that no one or more Holders shall have any
right in any manner  whatever by virtue of, or by availing of, any  provision of
this Indenture to affect,  disturb or prejudice the rights of any other Holders,

provided and for the equal and ratable benefit of all the Holders.


SECTION 508. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND
             INTEREST.

     Notwithstanding  any other provision in this  Indenture,  the Holder of any
Security shall have the right, which is absolute and  unconditional,  to receive
payment of the principal of (and  premium,  if any) and (subject to Section 309)
interest on such Security on the respective Stated Maturities  expressed in such
Security (or, in the case of redemption,  on the Redemption  Date or in the case
of an Offer to Purchase  made by the  Company and  required to be accepted as to
such Security,  on the Purchase Date) and to institute suit for the  enforcement
of any such payment,  and such rights shall not be impaired  without the consent
of such Holder.

right or remedy under this Indenture and such  proceeding has been  discontinued

to such Holder,  then and in every such case,  subject to any  determination  in
such  proceeding,  the  Company,  the Trustee and the Holders  shall be restored
severally and  respectively to their former  positions  hereunder and thereafter
all rights and remedies of the Trustee and the Holders shall  continue as though
no such proceeding had been instituted.

in addition to every other right and remedy given  hereunder or now or hereafter
existing at law or in equity or  otherwise.  The  assertion or employment of any
right or remedy  hereunder,  or  otherwise,  shall not  prevent  the  concurrent
assertion or employment of any other appropriate right or remedy.

SECTION 511. DELAY OR OMISSION NOT WAIVER.

     No delay or  omission  of the  Trustee or of any Holder of any  Security to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or  constitute  a waiver of any such Event of Default or an
acquiescence therein.  Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised  from time to time,  and as often
as may be deemed  expedient,  by the Trustee or by the Holders,  as the case may
be.

SECTION 512. CONTROL BY HOLDERS.

     The Holders of a majority  in  principal  amount at Stated  Maturity of the
Outstanding Securities shall have the right to direct the time, method and place
of  conducting  any  proceeding  for any  remedy  available  to the  Trustee  or
exercising any trust or power conferred on the Trustee, provided that

          (1) such  direction  shall not be in conflict  with any rule of law or
     with this Indenture, and

          (2) the Trustee may take any other action deemed proper by the Trustee
     which is not inconsistent with such direction.

SECTION 513.  WAIVER OF PAST DEFAULTS.

     The  Holders  of not less than a  majority  in  principal  amount at Stated
Maturity of the  Outstanding  Securities may on behalf of the Holders of all the
Securities  waive any past  default  hereunder  and its  consequences,  except a
default

          (1) in the  payment  of the  principal  of (or  premium,  if  any)  or
     interest on any Security  (including any Security which is required to have
     been purchased  pursuant to an Offer to Purchase which has been made by the
     Company), or

          (2) in respect of a covenant or provision  hereof which under  Article
     Nine  cannot be  modified  or amended  without the consent of the Holder of
     each Outstanding Security affected.

     Upon any such waiver,  such default shall cease to exist,  and any Event of
Default arising  therefrom shall be deemed to have been cured, for every purpose
of this  Indenture;  but no such waiver shall extend to any  subsequent or other
default or impair any right consequent thereon.

SECTION 514. 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, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an  undertaking to pay the costs of such suit, and may assess costs against
any such party  litigant,  in the manner and to the extent provided in the Trust
Indenture Act;  provided,  that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Company.

SECTION 515. WAIVER OF STAY OR EXTENSION LAWS.

     The Company  covenants  (to the extent that it may  lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or  advantage  of, any usury,  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  covenants  that it will not  hinder,
delay or impede the  execution of any power herein  granted to the Trustee,  but
will suffer and permit the  execution  of every such power as though no such law
had been enacted.

     costs, expenses and liabilities which might be incurred by it in compliance
     with such request or direction;

     instrument,  opinion, report, notice, request,  direction,  consent, order,
     bond,  debenture,  note,  other evidence of  indebtedness or other paper or

it would  have if it were  not  Trustee,  Authenticating  Agent,  Paying  Agent,
Security Registrar or such other agent.

                  The Company agrees:

          (1) to pay to the Trustee from time to time such  compensation  as the
     Company  and the  Trustee  shall from time to time agree in writing for all
     services rendered by it hereunder (which  compensation shall not be limited
     by any  provision of law in regard to the  compensation  of a trustee of an
     express trust);

          (2) except as otherwise  expressly  provided herein,  to reimburse the
     Trustee upon its request for all  reasonable  expenses,  disbursements  and
     advances  incurred or made by the Trustee in accordance  with any provision
     of this Indenture  (including the reasonable  compensation and the expenses
     and  disbursements  of its agents and  counsel),  except any such  expense,
     disbursement  or advance as may be  attributable  to its  negligence or bad
     faith; and

          (3) to indemnify the Trustee for, and to hold it harmless against, any
     and  all  loss,  damage,  claim,  liability  or  expense  incurred  without
     negligence  or bad faith on its part,  including  taxes  (other  than taxes
     based  upon,  measured  by or  determined  by the  revenue or income of the
     Trustee),   arising  out  of  or  in  connection  with  the  acceptance  or
     administration of this trust, including the costs and expenses of defending
     itself  against any claim or liability in  connection  with the exercise or

administration  under any applicable Federal or state bankruptcy,  insolvency or
other similar law.

Indenture.

SECTION 608. CONFLICTING INTERESTS.

     If the  Trustee  has or shall  acquire a  conflicting  interest  within the
meaning of the Trust  Indenture  Act, the Trustee  shall either  eliminate  such

Office in Chicago,  Illinois or the Borough of Manhattan,  The City of New York.
If such Person publishes reports of condition at least annually, pursuant to law

     (c) The  Trustee  may be  removed  at any time by Act of the  Holders  of a

the Trustee, or (ii) subject to Section 514, any Holder who has been a bona fide
Holder of a Security  for at least six months  may, on behalf of himself and all
others similarly situated,  petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

     (e) If the Trustee shall resign,  be removed or become incapable of acting,

Trustee so appointed shall, forthwith upon its acceptance of such appointment in

Trustee and  supersede  the successor  Trustee  appointed by the Company.  If no
successor Trustee shall have been so appointed by the Company or the Holders and

successor Trustee and the address of its Corporate Trust Office.


SECTION 611. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

     Every successor Trustee appointed hereunder shall execute,  acknowledge and
deliver to the Company and to the retiring Trustee an instrument  accepting such
appointment,  and thereupon the  resignation or removal of the retiring  Trustee
shall become effective and such successor Trustee, without any further act, deed
or  conveyance,  shall  become  vested with all the rights,  powers,  trusts and
duties of the retiring Trustee;  but, on request of the Company or the successor
Trustee,  such retiring Trustee shall, upon payment of its charges,  execute and
deliver an instrument  transferring  to such  successor  Trustee all the rights,
powers and trusts of the retiring  Trustee and shall duly  assign,  transfer and
deliver to such  successor  Trustee all property and money held by such retiring
Trustee hereunder. Upon request of any such successor Trustee, the Company shall
execute  any and all  instruments  for more fully and  certainly  vesting in and
confirming to such successor Trustee all such rights, powers and trusts.

SECTION 612.  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

     Any  corporation  into which the Trustee may be merged or converted or with
which it may be  consolidated,  or any  corporation  resulting  from any merger,
conversion  or  consolidation  to which  the  Trustee  shall be a party,  or any
corporation  succeeding to all or substantially all the corporate trust business
of the Trustee,  shall be the successor of the Trustee hereunder,  provided such
corporation  shall be  otherwise  qualified  and  eligible  under this  Article,
without the  execution  or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not  delivered,  by the Trustee  then in office,  any  successor  by merger,
conversion  or  consolidation  to such  authenticating  Trustee  may adopt  such
authentication  and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.


SECTION 613. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

     If and when the  Trustee  shall be or become a creditor  of the Company (or
any other  obligor  upon the  Securities),  the Trustee  shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).


SECTION 614. APPOINTMENT OF AUTHENTICATING AGENT.

     The Trustee may appoint an  Authenticating  Agent or Agents  which shall be
authorized  to act on behalf of the Trustee to  authenticate  Securities  issued
upon  original  issue and upon  exchange,  registration  of  transfer or partial
redemption or partial  purchase or pursuant to  Section 308,  and  Securities so
authenticated  shall be entitled to the benefits of this  Indenture and shall be
valid  and  obligatory  for all  purposes  as if  authenticated  by the  Trustee
hereunder.  Wherever  reference is made in this Indenture to the  authentication
and  delivery of  Securities  by the  Trustee or the  Trustee's  certificate  of
authentication,  such reference  shall be deemed to include  authentication  and
delivery on behalf of the Trustee by an  Authenticating  Agent and a certificate
of authentication executed

Agent shall be acceptable to the Company and shall at all times be a corporation
organized and doing business under the laws of the United States of America, any
State thereof or the District of Columbia,  authorized under such laws to act as
Authenticating  Agent,  having a combined  capital  and surplus of not less than
$50,000,000  and  subject  to  supervision  or  examination  by Federal or State
authority.  If such Authenticating Agent publishes reports of condition at least
annually,  pursuant  to  law or to  the  requirements  of  said  supervising  or
examining authority, then for the purposes of this Section, the combined capital
and  surplus of such  Authenticating  Agent  shall be deemed to be its  combined
capital  and  surplus as set forth in its most  recent  report of  condition  so
published.  If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section,  such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

     Any  corporation  into  which an  Authenticating  Agent  may be  merged  or
converted or with which it may be  consolidated,  or any  corporation  resulting
from any merger,  conversion or consolidation to which such Authenticating Agent
shall be a party,  or any  corporation  succeeding  to the  corporate  agency or
corporate  trust business of an  Authenticating  Agent,  shall continue to be an
Authenticating  Agent,  provided such  corporation  shall be otherwise  eligible
under this Section,  without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

     An  Authenticating  Agent may resign at any time by giving  written  notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an  Authenticating  Agent by giving written notice thereof to such
Authenticating  Agent  and to the  Company.  Upon  receiving  such a  notice  of
resignation  or  upon  such  a  termination,   or  in  case  at  any  time  such
Authenticating  Agent  shall  cease  to  be  eligible  in  accordance  with  the
provisions of this Section,  the Trustee may appoint a successor  Authenticating
Agent  which  shall be  acceptable  to the Company and shall give notice of such
appointment in the manner provided in Section 106, to all Holders as their names
and addresses  appear in the Security  Register.  Any  successor  Authenticating
Agent upon acceptance of its appointment  hereunder shall become vested with all
the rights, powers and duties of its predecessor hereunder,  with like effect

Authenticating Agent shall be appointed unless eligible under the provisions of
this Section.

     The Company  agrees to pay to each  Authenticating  Agent from time to time
reasonable compensation for its services under this Section.

and the  Company  hereby  appoints  the Trustee as its agent to receive all
such  presentations,  surrenders,  notices  and  demands.  In the event any such
notice or  demands  are so made or  served  on the  Trustee,  the  Trustee  will
promptly forward copies thereof to the Company.

     The Company may also from time to time  designate one or more other offices
or agencies (in or outside the Borough of Manhattan, The City of New York) where
the Securities may be presented or surrendered  for any or all such purposes and
may from time to time rescind such designations; provided, however, that no such
designation  or  rescission  shall in any  manner  relieve  the  Company  of its
obligation to maintain an office or agency in the Borough of Manhattan, The City
of New York, for such  purposes.  The Company will give prompt written notice to
the  Trustee  of any such  designation  or  rescission  and of any change in the
location of any such other office or agency.


SECTION 1003. MONEY FOR SECURITY PAYMENTS TO BE HELD IN TRUST.

     If the Company shall at any time act as its own Paying  Agent,  it will, on
or before each due date of the principal of (and premium, if any) or interest on
any of the  Securities,  segregate  and hold in  trust  for the  benefit  of the
Persons entitled thereto a sum sufficient to pay the principal (and premium,  if
any) or interest so becoming  due until such sums shall be paid to such  Persons
or otherwise disposed of as herein provided and will promptly notify the Trustee
of its action or failure so to act.

     Whenever the Company shall have one or more Paying Agents,  it will,  prior
to each due date of the  principal of (and  premium,  if any) or interest on any
Securities,  deposit with a Paying Agent a sum  sufficient  to pay the principal
(and  premium,  if any) or  interest  so  becoming  due,  such sum to be held as
provided  by the Trust  Indenture  Act,  and (unless  such  Paying  Agent is the
Trustee) the Company will  promptly  notify the Trustee of its action or failure
so to act.

     The Company  will cause each Paying Agent other than the Trustee to execute
and deliver to the Trustee an  instrument in which such Paying Agent shall agree
with the Trustee,  subject to the  provisions of this Section,  that such Paying
Agent will: (i) comply with the provisions of the Trust Indenture Act applicable

<PAGE>

to it as Paying Agent and (ii) during the continuance of any default by the
Company (or any other obligor upon the  Securities) in the making of any payment
in respect of the Securities, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent as such.

     The Company may at any time, for the purpose of obtaining the  satisfaction
and  discharge of this  Indenture or for any other  purpose,  pay, or by Company
Order  direct any Paying  Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying  Agent,  such sums to be held by the Trustee upon the
same  trusts as those  upon  which  such sums were held by the  Company  or such
Paying Agent;  and,  upon such payment by any Paying Agent to the Trustee,  such
Paying Agent shall be released from all further  liability  with respect to such
money.

     Any money  deposited with the Trustee or any Paying Agent,  or then held by
the Company,  in trust for the payment of the principal of (and premium, if any)
or interest on any Security  and  remaining  unclaimed  for two years after such
principal (and premium,  if any) or interest has become due and payable shall be
paid to the Company on Company  Request,  or (if then held by the Company) shall
be discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor,  look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust
money,  and all  liability of the Company as trustee  thereof,  shall  thereupon
cease;  provided,  however,  that the Trustee or such Paying Agent, before being
required to make any such repayment,  may at the expense of the Company cause to
be published once, in a newspaper published in the English language, customarily
published  on each  Business Day and of general  circulation  in The City of New
York,  notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication,
any  unclaimed  balance  of such  money  then  remaining  will be  repaid to the
Company.


SECTION 1004. EXISTENCE.

     Subject  to  Article  Eight,  the  Company  will do or cause to be done all
things  necessary to preserve  and keep in full force and effect its  existence,
rights (charter and statutory) and material franchises;  provided, however, that
the Company

shall not be required to preserve  any such right or franchise if the Board
of Directors in good faith shall determine that the  preservation  thereof is no
longer desirable in the conduct of the business of the Company and that the loss
thereof is not disadvantageous in any material respect to the Holders.


SECTION 1005.  MAINTENANCE OF PROPERTIES.

     The  Company  will  cause  all  material  properties  used or useful in the
conduct of its  business or the  business  of any  Restricted  Subsidiary  to be
maintained  and kept in good  condition,  repair and working  order and supplied
with all necessary  equipment  and will cause to be made all necessary  repairs,
renewals,  replacements,  betterments and  improvements  thereof,  all as in the
judgment of the  Company may be  necessary  so that the  business  carried on in
connection therewith may be properly and advantageously  conducted at all times;
provided,  however,  that nothing in this Section shall prevent the Company from
discontinuing the operation or maintenance of any of such material properties if
such  discontinuance  is, as determined by the Board of Directors in good faith,
desirable  in the  conduct of its  business or the  business  of any  Restricted
Subsidiary and not disadvantageous in any material respect to the Holders.


SECTION 1006.  PAYMENT OF TAXES AND OTHER CLAIMS.

     The Company will pay or discharge or cause to be paid or discharged, before
the same shall become  delinquent,  (1) all taxes,  assessments and governmental
charges levied or imposed upon the Company or any of its Restricted Subsidiaries
or upon the income,  profits or property of the Company or any of its Restricted
Subsidiaries, and (2) all lawful claims for labor, materials and supplies which,
if unpaid, might by law become a lien upon the property of the Company or any of
its Restricted  Subsidiaries;  provided,  however, that the Company shall not be
required to pay or  discharge  or cause to be paid or  discharged  any such tax,
assessment,  charge or claim whose  amount,  applicability  or validity is being
contested in good faith by appropriate proceedings.

SECTION 1007.  MAINTENANCE OF INSURANCE.

     The Company shall, and shall cause its Restricted  Subsidiaries to, keep at
all  times all of their  properties  which are of an  insurable  nature  insured
against loss or damage with insurers  believed by the Company to be  responsible
to the  extent  that  property  of  similar  character  is usually so insured by
corporations  similarly  situated and owning like  properties in accordance with
good  business  practice.  The Company  shall,  and shall  cause its  Restricted
Subsidiaries  to, use the  proceeds  from any such  insurance  policy to repair,
replace or otherwise  restore all  material  properties  to which such  proceeds
relate,  provided,  however,  that the Company  shall not be required to repair,
replace  or  otherwise  restore  any  such  material  property  if the  Board of
Directors  in good faith  determines  that such  inaction  is  desirable  in the
conduct of the  business of the  Company or any  Restricted  Subsidiary  and not
disadvantageous in any material respect to the Holders.


SECTION 1008. LIMITATION ON CONSOLIDATED DEBT.

     The Company shall not, and shall not permit any  Restricted  Subsidiary to,
Incur any Debt (including  Acquired Debt), other than Permitted Debt, unless (i)
with  respect to Debt  Incurred  under this clause (i), the Debt so Incurred and
outstanding is in an aggregate principal amount that does not exceed 2.25 times,
with respect to Capital  Stock sales after June 1, 1997 and on or prior to March
31, 1998,  or 2.00 times,  with  respect to Capital  Stock sales after March 31,
1998, the aggregate amount of net cash proceeds (or 80% of the Fair Market Value
of property other than cash) received by the Company after June 1, 1997 from the
issuance  and sale  (other  than to a  Restricted  Subsidiary)  of shares of its
Capital Stock (other than Redeemable  Stock), or any options,  warrants or other
rights to purchase such Capital Stock (other than Redeemable Stock),  other than
(x) proceeds applied for use as a Directed  Investment  (unless such designation
has been revoked by the Board of Directors and the Company  either  abandons its
plans to make such  Investment  or is able to make such  Investment  pursuant to
Section 1009 (other than as a Directed  Investment)) and (y) proceeds which have
been  included  in the  computation  of the  amounts  available  for  Restricted
Payments  pursuant to clause (c)(2) of Section 1009, to the extent the inclusion
thereof was  necessary to allow a subsequent  Restricted  Payment to be made, or
(ii) on the date of such

Incurrence, after giving effect to the Incurrence of such Debt (or Acquired
Debt) and the receipt and  application of the net proceeds  thereof (and, if the
net  proceeds  of such new Debt are used to  acquire  a Person  that  becomes  a
Restricted  Subsidiary  or an operating  business of the Company or a Restricted
Subsidiary,  to all  terms  of  such  acquisition)  on a pro  forma  basis,  the
Operating Cash Flow to Consolidated Interest Expense Ratio would equal or exceed
1.75 to 1.


SECTION 1009.  LIMITATION ON RESTRICTED PAYMENTS.

     The Company shall not, directly or indirectly:

          (i) declare or pay any  dividend on, or make any  distribution  to the
     holders  of, any shares of its  Capital  Stock  (other  than  dividends  or
     distributions  payable  solely in its Capital Stock (other than  Redeemable

Subsidiary Funding Company so long as (x) such Investments are invested in McCaw

     Notwithstanding the foregoing limitations in this Section 1009, the Company
will be permitted to make any  Investment in a Person that is not (either before
or after giving  effect  thereto) a Subsidiary  of the Company,  provided  that,
immediately  after giving effect thereto,  the amount equal to (a) the aggregate
amount of all  Investments  made pursuant to this  paragraph  minus (b) all cash
received by the Company or any Restricted  Subsidiary from the sale, transfer or
other  disposition  to a Person that is not a  Subsidiary  of the Company of any
such Investment (or portion thereof) included in such aggregate amount (with the
amount of cash to be counted  for this  purpose not to exceed the amount of such
Investment  (or portion  thereof) so included),  shall not exceed the greater of
(i) $250 million  and (ii) 2% of the Total Market Value of Equity of the Company

thereof (to the extent such portion  constitutes an Investment) at the time such
Investment is made,  as  determined by the Board of Directors  (whose good faith
determination shall be conclusive and evidenced by a Board Resolution).

     Notwithstanding  the foregoing,  no Investment in a Person that immediately
thereafter  would be a Restricted  Subsidiary will be a Restricted  Payment.  In
addition,  if any  Person  in which an  Investment  is  made,  which  Investment
constitutes  a  Restricted

Investments  previously  made in such  Person  shall no  longer  be  counted  as
Restricted  Payments  for  purposes  of  calculating  the  aggregate  amount  of
Restricted  Payments pursuant to clause (c) of the third preceding  paragraph or
the aggregate  amount of Investments  pursuant to clause (a) of the  immediately
preceding paragraph, in each case to the extent such Investments would otherwise
be so counted.

     For  purposes of clause  (c)(3)  above,  the net  proceeds  received by the
Company  from  the  issuance  or sale  of its  Capital  Stock  either  upon  the
conversion of, or exchange for, Debt of the Company or any Restricted Subsidiary
shall be deemed to be an amount equal to (a) the sum of (i) the principal amount
or  accreted  value  (whichever  is  less)  of  such  Debt  on the  date of such
conversion  or exchange  and (ii) the  additional  cash  consideration,  if any,
received by the Company upon such  conversion  or exchange,  less any payment on
account of fractional shares, minus (b) all expenses incurred in connection with
such issuance or sale. In addition, for purposes of clause (c)(3) above, the net
proceeds  received by the Company from the issuance or sale of its Capital Stock
upon the  exercise of any  options or warrants of the Company or any  Restricted
Subsidiary  shall be deemed to be an amount  equal to  (a) the  additional  cash
consideration, if any, received by the Company upon such exercise, minus (b) all
expenses incurred in connection with such issuance or sale.

     For  purposes of this Section  1009,  if a  particular  Restricted  Payment
involves a non-cash  payment,  including  a  distribution  of assets,  then such
Restricted  Payment shall be deemed to be an amount equal to the cash portion of
such Restricted  Payment,  if any, plus an amount equal to the fair market value
of the non-cash portion of such Restricted  Payment,  as determined by the Board
of Directors (whose good faith  determination  shall be conclusive and evidenced
by a Board Resolution).

Restricted  Subsidiary to, sell,  convey,  transfer or otherwise  dispose of any
assets, other than in the ordinary

course of  business,  to any  Unrestricted  Subsidiary  or any Person  that
becomes an Unrestricted  Subsidiary as part of such transaction,  unless,  after
giving effect to any such action,  the assets (not including any assets so sold,
conveyed,  transferred  or  otherwise  disposed  of,  other than in the ordinary
course of business, to any Unrestricted Subsidiary or any Person that becomes an
Unrestricted Subsidiary as part of such transaction) and business of the Company
and its  remaining  Restricted  Subsidiaries  generated  at least 90% of Digital
Mobile-SMR  Operating  Cash  Flow in the  fiscal  quarter  of the  Company  most
recently completed prior to the date of such action.

     The Board of Directors may designate any existing  Unrestricted  Subsidiary
or any  Person  that is  about  to  become  a  Subsidiary  of the  Company  as a
Restricted  Subsidiary  if,  after giving  effect to such action  (and,  if such
designation  is made in  connection  with  the  acquisition  of a  Person  or an
operating  business that is about to become a Subsidiary  of the Company,  after
giving  effect to all terms of such  acquisition)  on a pro forma basis,  on the
date of such action, the Debt, if any, of such Unrestricted Subsidiary or Person
outstanding  immediately  prior to such designation would have been permitted to
be Incurred (and shall be deemed to have been Incurred) for all purposes of this
Indenture.

     Subject to the second preceding paragraph and compliance with Section 1009,
the  Board  of  Directors  may  designate  any   Restricted   Subsidiary  as  an
Unrestricted Subsidiary.

     The designation by the Board of Directors of a Restricted  Subsidiary as an
Unrestricted  Subsidiary  shall,  for all  purposes of  Section 1009  (including
clause (b) thereof),  be deemed to be a Restricted Payment of an amount equal to
the fair market value of the  Company's  ownership  interest in such  Subsidiary
(including,  without  duplication,  such  indirect  ownership  interest  in  all
Subsidiaries  of such  Subsidiary),  as  determined by the Board of Directors in
good faith and evidenced by a Board Resolution.


     Notwithstanding the foregoing provisions of this Section 1010, the Board of
Directors may not  designate a Subsidiary  of the Company to be an  Unrestricted
Subsidiary  if,  after  such  designation,  (a) the  Company or any of its other
Restricted  Subsidiaries (i) provides credit support for, or a Guarantee of, any
Debt of such  Subsidiary  (including  any  undertaking,  agreement or instrument
evidencing such Debt) or

(ii) is directly or indirectly liable for any Debt of such Subsidiary,  (b)
a default with respect to any Debt of such Subsidiary (including any right which
the holders thereof may have to take enforcement action against such Subsidiary)
would permit (upon  notice,  lapse of time or both) any holder of any other Debt
of the Company or any  Restricted  Subsidiary to declare a default on such other
Debt or cause the  payment  thereof to be  accelerated  or payable  prior to its
final  scheduled  maturity or (c) such  Subsidiary owns any Capital Stock of, or
owns or holds any Lien on any property of, any  Restricted  Subsidiary  which is
not a Subsidiary of the Subsidiary to be so designated.

     The Board of Directors, from time to time, may designate any Person that is
about to become a Subsidiary of the Company as an Unrestricted  Subsidiary,  and
may designate any newly-created Subsidiary as an Unrestricted Subsidiary,  if at
the time such  Subsidiary  is created it contains no assets  (other than such de
minimis amount of assets then required by law for the formation of corporations)
and no Debt. Subsidiaries of the Company that are not designated by the Board of
Directors  as  Restricted  or  Unrestricted  Subsidiaries  shall be deemed to be
Restricted  Subsidiaries.  Notwithstanding  any provisions of this Section 1010,
all   Subsidiaries   of  an  Unrestricted   Subsidiary   shall  be  Unrestricted
Subsidiaries.  The Board of  Directors  shall not  change the  designation  of a
Subsidiary of the Company more than twice in any period of five years.


Transactions with Affiliates.ith Affiliates

     The Company shall not, and shall not permit any  Restricted  Subsidiary to,
directly or  indirectly,  enter into any  transaction  (including  the purchase,
sale,  lease or exchange of any  property or the  rendering  of any  service) or
series of related  transactions  with any Affiliate of the Company on terms that
are less favorable to the Company or such Restricted Subsidiary, as the case may
be, than those which  might be obtained at the time of such  transaction  from a
Person that is not such an Affiliate;  provided, however, that this Section 1011
shall not limit, or be applicable to, (i) any transaction  between  Unrestricted
Subsidiaries  not involving the Company or any Restricted  Subsidiary,  (ii) any
transaction  between  the  Company  and any  Restricted  Subsidiary  or  between
Restricted  Subsidiaries or (iii) any Permitted  Transactions.  In addition, any
transaction or series of related transactions, other than Permitted

Affiliate  of the Company  (other than a  Restricted  Subsidiary)  involving  an
aggregate  consideration of $5 million or more must be approved in good faith by
a majority of the Company's  Disinterested  Directors (of which there must be at
least  one)  and  evidenced  by  a  Board  Resolution.   For  purposes  of  this
Section 1011,  any  transaction  or series of related  transactions  between the
Company or any  Restricted  Subsidiary  and an  Affiliate of the Company that is
approved by a majority of the Disinterested Directors (of which there must be at
least one) and evidenced by a Board Resolution shall be deemed to be on terms as
favorable  as those that might be obtained at the time of such  transaction  (or
series of  transactions)  from a Person that is not such an  Affiliate  and thus
shall be permitted under this Section 1011.

               (5)  the  place  or  places  where  such  Securities  are  to  be
          surrendered for payment of the Redemption Price, and

               (6) if the redemption is being made pursuant to the provisions of
          the  Securities  set forth in the third  paragraph  of Section  203, a
          brief  description  of the nature and amount of Capital  Stock sold by
          the Company,  the  aggregate  purchase  price thereof and the net cash
          proceeds therefrom available for such redemption, the date or dates on
          which such sale was  completed  and the  percentage  of the  aggregate
          Accreted Value of Outstanding Securities being redeemed.

     Notice of  redemption  of  Securities to be redeemed at the election of the
Company  shall be given by the  Company  or, at the  Company's  request,  by the
Trustee in the name and at the expense of the Company and shall be irrevocable.


SECTION 1106. DEPOSIT OF REDEMPTION PRICE.

     Prior to any Redemption Date, the Company shall deposit with the Trustee or
with a Paying  Agent (or,  if the  Company  is acting as its own  Paying  Agent,
segregate  and hold in trust as  provided  in  Section  1003) an amount of money
sufficient to pay the Redemption  Price of, and (except if the  Redemption  Date
shall be an Interest  Payment Date) any applicable  accrued interest on, all the
Securities which are to be redeemed on that date.


SECTION 1107. SECURITIES PAYABLE ON REDEMPTION DATE.

     Notice of redemption  having been given as aforesaid,  the Securities so to

Redemption  Price  therein  specified,  and from and after such date (unless the
Company shall default in the payment of the Redemption  Price and any applicable
accrued interest) such Securities shall not bear interest and the Accreted Value
of such Securities  shall thereupon and thereafter  conclusively be deemed to be
their  Accreted  Value  determined  on  and as of  such  Redemption  Date.  Upon
surrender of any such Security for  redemption  in accordance  with said notice,
such Security  shall be paid by the Company at the  Redemption  Price,  together
with  any  applicable  accrued  and  unpaid  interest  to the  Redemption  Date;
provided, however, that installments of interest

payable  to  the  Holders  of  such  Securities,  or  one  or  more  Predecessor
Securities,  registered as such at the close of business on the relevant  Record
Dates according to their terms and the provisions of Section 309.

     If any Security  called for  redemption in accordance  with the election of
the Company made  pursuant to Section  1101 shall not be so paid upon  surrender
thereof for redemption,  the principal (and premium,  if any) shall, until paid,
bear interest from the Redemption Date at the rate provided by the Security.


SECTION 1108. SECURITIES REDEEMED IN PART.

     Any Security  which is to be redeemed only in part shall be  surrendered at
an office or agency of the  Company  designated  for that  purpose  pursuant  to
Section 1002  (with, if the Company or the Trustee so requires,  due endorsement
by, or a written  instrument of transfer in form satisfactory to the Company and
the Trustee duly executed by, the Holder thereof or his attorney duly authorized
in writing),  and the Company shall execute,  and the Trustee shall authenticate
and  deliver  to the  Holder of such  Security  without  service  charge,  a new
Security or  Securities,  of any  authorized  denomination  as requested by such
Holder,  in  aggregate  principal  amount  at  Stated  Maturity  equal to and in
exchange for the unredeemed  portion of the principal  amount at Stated Maturity
of the Security so surrendered.

                     Defeasance and Covenant Defeasance

SECTION 1201. COMPANY'S OPTION TO EFFECT DEFEASANCE OR COVENANT DEFEASANCE.

     The Company may elect,  at its option at any time,  to have Section 1202 or
Section 1203 applied to the Outstanding  Securities (as a whole and not in part)
upon  compliance  with the conditions set forth below in this Article.  Any such
election shall be evidenced by a Board Resolution.

SECTION 1202. DEFEASANCE AND DISCHARGE.

     Upon the Company's  exercise of its option to have this Section  applied to
the  Outstanding  Securities (as a whole and not in part),  the Company shall be
deemed  to have  been  discharged  from its  obligations  with  respect  to such
Securities as provided in this Section on and after the date the  conditions set
forth in Section  1204 are  satisfied  (hereinafter  called  "Defeasance"),  and
thereafter such Securities shall not be subject to redemption  pursuant thereto.
For this purpose, such Defeasance means that the Company shall be deemed to have
paid and discharged the entire  indebtedness  represented by such Securities and
to have  satisfied  all its other  obligations  under such  Securities  and this
Indenture  insofar as such  Securities  are concerned  (and the Trustee,  at the
expense of the Company,  shall  execute  proper  instruments  acknowledging  the
same),  subject to the following which shall survive until otherwise  terminated
or  discharged  hereunder:  (1) the  rights of  Holders  of such  Securities  to
receive,  solely from the trust fund described in Section 1204 and as more fully
set forth in such  Section,  payments  in  respect of the  principal  of and any
premium and interest on such Securities when payments are due, (2) the Company's
obligations with respect to such Securities under  Sections 304,  305, 308, 1002
and 1003, (3) the rights,  powers,  trusts, duties and immunities of the Trustee
hereunder and (4) this  Article.  Subject to compliance  with this Article,  the
Company may exercise its option to have this Section  applied to the Outstanding
Securities  (as a whole and not in part)  notwithstanding  the prior exercise of
its option to have Section 1203 applied to such Securities.

SECTION 1203. COVENANT DEFEASANCE.

     Upon the Company's  exercise of its option to have this Section  applied to
the Outstanding  Securities (as a whole and not in part),  (1) the Company shall
be released from its obligations under Section  801(iii),  Sections 1005 through
1016,  inclusive,  and any covenant  provided pursuant to Section 901(2) and (2)
the occurrence of any event specified in Section 501(4) (with respect to Section
801(iii)),  Section  501(5) (with  respect to any of Sections 1005 through 1016,
inclusive,  and any such covenants provided pursuant to Section 901(2)), Section
501(6) or  Section  501(7)  shall be  deemed  not to be or result in an Event of
Default,  in each case with  respect  to such  Securities  as  provided  in this
Section  on and after the date the  conditions  set  forth in  Section 1204  are
satisfied  (hereinafter called "Covenant  Defeasance").  For this purpose,  such
Covenant Defeasance means that, with respect to such Securities, the Company may
omit to  comply  with and  shall  have no  liability  in  respect  of any  term,
condition or limitation set forth in any such  specified  Section (to the extent
so specified in the case of Sections  501(4) and  501(5)),  whether  directly or
indirectly by reason of any reference elsewhere herein to any such Section or by
reason of any reference in any such Section to any other provision  herein or in
any other  document,  but the remainder of this  Indenture  and such  Securities
shall be unaffected thereby.


SECTION 1204. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

     The following shall be the conditions to the application of Section 1202 or
Section 1203 to the Outstanding Securities:

          (1) The  Company  shall  irrevocably  have  deposited  or caused to be
     deposited  with  the  Trustee  (or  another  trustee  which  satisfies  the
     requirements  contemplated  by Section  609 and  agrees to comply  with the
     provisions  of this Article  applicable  to it) as trust funds in trust for
     the  purpose  of making the  following  payments,  specifically  pledged as
     security for, and dedicated  solely to, the benefits of the Holders of such
     Securities,  (A) money in an  amount,  or (B) U.S.  Government  Obligations

     thereof in accordance with their terms will provide, not later than one day
     before the due date of any payment, money in an amount,

          or (C) a combination thereof, in each case sufficient,  in the opinion
     of a nationally recognized firm of independent public accountants expressed
     in a written  certification  thereof  delivered to the Trustee,  to pay and
     discharge,  and which  shall be applied by the  Trustee  (or any such other
     qualifying  trustee)  to pay  and  discharge,  the  principal  of  and  any
     installment  of  interest  on  such  Securities  on the  respective  Stated
     Maturities thereof, in accordance with the terms of this Indenture and such
     Securities.  As used herein,  "U.S.  Government  Obligation"  means (x) any
     security  which is (i) a direct  obligation of the United States of America
     for the payment of which the full faith and credit of the United  States of
     America  is  pledged  or (ii)  an  obligation  of a  Person  controlled  or
     supervised  by and  acting as an agency or  instrumentality  of the  United
     States of America the payment of which is  unconditionally  guaranteed as a
     full faith and credit obligation by the United States of America, which, in
     either case (i) or (ii), is not callable or redeemable at the option of the
     issuer thereof, and (y) any depository receipt issued by a bank (as defined
     in Section  3(a)(2) of the Securities Act) as custodian with respect to any
     U.S. Government  Obligation which is specified in Clause (x) above and held
     by such bank for the account of the holder of such depository  receipt,  or
     with  respect to any  specific  payment of  principal of or interest on any
     U.S.  Government  Obligation which is so specified and held,  provided that
     (except as required by law) such  custodian is not  authorized  to make any
     deduction from the amount payable to the holder of such depository  receipt
     from any amount received by the custodian in respect of the U.S. Government
     Obligation  or the specific  payment of principal or interest  evidenced by
     such depository receipt.

          (2) In the event of an  election  to have  Section  1202  apply to the
     Outstanding Securities,  the Company shall have delivered to the Trustee an
     Opinion of Counsel stating that (A) the Company has received from, or there
     has been published by, the Internal  Revenue  Service a ruling or (B) since
     the Closing Date there has been a change in the  applicable  Federal income
     tax law, in either case (A) or (B) to the effect  that,  and based  thereon
     such opinion shall confirm that,  the Holders of such  Securities  will not
     recognize  gain or loss for Federal  income tax purposes as a result of the
     deposit,  Defeasance  and  discharge  to be effected  with  respect to such
     Securities and will be subject

     to Federal  income tax on the same  amount,  in the same manner and at
     the  same  times  as would  be the  case if such  deposit,  Defeasance  and
     discharge were not to occur.

          (3) In the event of an  election  to have  Section  1203  apply to the
     Outstanding Securities,  the Company shall have delivered to the Trustee an
     Opinion of Counsel to the effect that the Holders of such  Securities  will
     not recognize  gain or loss for Federal  income tax purposes as a result of
     the deposit and  Covenant  Defeasance  to be effected  with respect to such
     Securities and will be subject to Federal income tax on the same amount, in
     the same manner and at the same times as would be the case if such  deposit
     and Covenant Defeasance were not to occur.

          (4) No Default with respect to the Outstanding  Securities  shall have
     occurred and be  continuing  at the time of such deposit or, with regard to
     any such event  specified  in  Sections  501(8) and (9),  at any time on or
     prior to the 90th day after the date of such  deposit (it being  understood
     that this  condition  shall not be deemed  satisfied  until after such 90th
     day).

          (5) Such Defeasance or Covenant Defeasance shall not cause the Trustee
     to have a conflicting  interest  within the meaning of the Trust  Indenture
     Act  (assuming  all  Securities  are in default  within the meaning of such
     Act).

          (6) Such  Defeasance  or  Covenant  Defeasance  shall not  result in a
     breach or violation of, or constitute a default under,  any other agreement
     or instrument to which the Company is a party or by which it is bound.

          (7) Such  Defeasance  or Covenant  Defeasance  shall not result in the
     trust arising from such deposit  constituting an investment  company within
     the  meaning  of the  Investment  Company  Act unless  such trust  shall be
     registered under such Act or exempt from registration thereunder.

          (8) The  Company  shall have  delivered  to the  Trustee an  Officers'
     Certificate  and an Opinion of Counsel,  each stating  that all  conditions
     precedent with respect to such Defeasance or Covenant  Defeasance have been
     complied with.

SECTION 1205.  DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
               TRUST; MISCELLANEOUS PROVISIONS.

     Subject to the provisions of the last paragraph of Section 1003,  all money
and U.S. Government  Obligations (including the proceeds thereof) deposited with
the Trustee or other qualifying trustee (solely for purposes of this Section and
Section 1206,   the  Trustee  and  any  such  other   trustee  are  referred  to
collectively  as the  "Trustee")  pursuant  to  Section 1204  in  respect of the
Outstanding  Securities  shall be held in trust and applied by the  Trustee,  in
accordance  with the provisions of such  Securities and this  Indenture,  to the
payment, either directly or through any such Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine,  to the Holders of
such  Securities,  of all sums due and to  become  due  thereon  in  respect  of
principal and any premium and  interest,  but money so held in trust need not be
segregated from other funds except to the extent required by law.

     The Company  shall pay and  indemnify  the Trustee  against any tax, fee or
other  charge  imposed on or assessed  against the U.S.  Government  Obligations
deposited  pursuant to  Section 1204  or the principal and interest  received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

     Anything in this Article to the contrary notwithstanding, the Trustee shall
deliver or pay to the Company from time to time upon  Company  Request any money
or U.S. Government  Obligations held by it as provided in Section 1204 which, in
the opinion of a nationally  recognized firm of independent  public  accountants
expressed in a written  certification  thereof delivered to the Trustee,  are in
excess of the amount  thereof  which would then be required to be  deposited  to
effect the Defeasance or Covenant  Defeasance,  as the case may be, with respect
to the Outstanding Securities.

SECTION 1206. REINSTATEMENT.

     If the  Trustee  or the  Paying  Agent  is  unable  to apply  any  money in
accordance  with this Article with  respect to any  Securities  by reason of any
order or judgment of any court or governmental authority enjoining,  restraining
or otherwise  prohibiting  such  application,  then the  obligations  under this
Indenture  and such  Securities  from which the Company has been  discharged  or
released  pursuant to Section  1202 or 1203 shall be revived and  reinstated  as
though no deposit had  occurred  pursuant to this  Article  with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 1205 with respect to such Securities
in accordance with this Article;  provided,  however,  that if the Company makes
any payment of  principal  of or any  premium or  interest on any such  Security
following such reinstatement of its obligations, the Company shall be subrogated
to the rights (if any) of the Holders of such Securities to receive such payment
from the money so held in trust.
