Item 5.   Other Events

On September 26, 1997,  General DataComm  Industries,  Inc. (the  "Corporation")
sold  $25,000,000   principal  amount  of  a  new  7-3/4%   Convertible   Senior
Subordinated  Debenture  issue  due  2002  ("7-3/4%  Debentures")  to a group of
qualified  institutional  buyers and  institutional  accredited  investors.  The
proceeds  will be used  primarily to fund  operating  and  investing  activities
including,   but  not  limited  to,  the   development   and  expansion  of  the
Corporation's Asynchronous Transfer Mode (ATM) business.

The  7-3/4%  Debentures  can be  converted  at any time into  Common  Stock at a
conversion  price of $6.86 a share,  or the  equivalent of  approximately  145.8
shares of Common Stock for each $1,000  principal  amount of 7-3/4%  Debentures.
Such conversion  price will be reset on each of March 30, 1998 and September 30,
1999 (each a "Reset  Date") to the average  closing price (as defined) of Common
Stock for the ten previous trading days preceding a Reset Date plus the original
premium thereof if lower than the initial  conversion price, but in no event may
the  conversion  price be reset at a price  lower  than 15%  below  the  initial
conversion price or be reset on the second Reset Date at a price higher than the
conversion price set on the first Reset Date.

The 7-3/4%  Debentures may not be redeemed at the option of the Company prior to
September 30, 2000. The 7-3/4% Debentures are redeemable in whole or in part, at
the  option  of the  Company, at any time on or after  September  30,  2000  at
specified  redemption  prices plus accrued  interest to the date of  redemption,
provided,  however,  that the 7-3/4%  Debentures are not redeemable on and after
September  30, 2000 and prior to September  30, 2001 unless the closing price of
the Common Stock has equaled or exceeded 150% of the conversion  price per share
then in effect for at least 20 trading days within 30  consecutive  trading days
ending within five trading days before notice of redemption is mailed.

The 7-3/4%  Debentures  will be subordinated in right of payment to all existing
and future  senior  indebtedness  of the  Corporation.  During the 30-day period
commencing  September 30, 2000, each holder of the 7-3/4%  Debentures shall have
the right to require the Corporation to repurchase  such 7-3/4%  Debentures at a
repurchase  price in cash equal to 100% of the principal  amount  thereof,  plus
accrued  and unpaid  interest.  The  Corporation  may  satisfy  such  repurchase
obligations  through the issuance of nonconvertible  senior  subordinated  notes
which are  subordinated  to the same extent and due on the same maturity date as
the  7-3/4%  Debentures  and having  substantially  the same terms as the 7-3/4%
Debentures,  except such notes shall not be convertible and shall bear a rate of
interest in order to have a market  value of 100% of their  principal  amount on
the date of  repurchase,  as  determined by a nationally  recognized  investment
banking firm chosen by the  Corporation;  provided  that the interest rate shall
not exceed 14% per annum.  Reference is made to Exhibit 4 to this Report for all
of the terms and conditions of the 7-3/4% Debentures.

Item 5.  Other Events (continued)

The 7-3/4%  Debentures were not registered  under the Securities Act of 1933 and
may not be offered  or sold in the United  States  without  registration  unless
pursuant to an applicable exemption from the registration requirements,  such as
Rule 144A on a sale to a qualified  institutional  buyer.  The  Corporation  has
agreed to file a  registration statement, for the 7-3/4% Debentures  and Common
Stock into which the 7-3/4%  Debentures are convertible,under the Securities Act
of 1933,  as amended,  within  ninety (90) days from the date of  issuance.  The
Corporation  was  represented by Utendahl  Capital  Partners,  L.P. as Placement
Agent.

whole or in part which if in part  shall be $1,000 or an  integral  multiple  of
$1,000,  shall be given by mailing a notice of such redemption not later than on

the registration books, all as provided in the Indenture.

                The Indenture  provides that under the  circumstances  specified
therein  funds may be  deposited  with the  Trustee or with any paying  agent in
advance of the maturity or redemption  date of any of the  Debentures,  in trust
for the payment or  redemption of such  Debentures,  and payment of the interest
due or to become due thereon,  and that thereupon all obligations of the Company
in  respect  of such  Debentures  shall  cease  and be  discharged  (except  any
obligations  to  provide  for  the  registration  of  transfer  or  exchange  of
Debentures) and subject to the provisions

                                       6
<PAGE>

of Article  Fourteen of the Indenture,  the holders thereof shall  thereafter be
restricted  exclusively to such funds for any and all other claims on their part
under the Indenture or with respect to such Debentures.

                The  Debentures  are issuable as registered  debentures  without
coupons in  denominations  of $1,000 and any integral  multiple of $1,000.  Upon
surrender of this Debenture for registration of transfer at the  above-mentioned
office or agency of the Company,  a new Debenture or  Debentures,  of authorized
denominations,  for a like  aggregate  principal  amount,  will be issued to the
transferee as provided,  and subject to the  limitations,  in the Indenture.  No
service  charge  will be made for any such  registration  of  transfer,  but the
Company may require  payment of a sum  sufficient to reimburse it for any tax or
other  governmental  charge  that may be imposed in relation  thereto;  and this
Debenture may in like manner be exchanged without service charge for one or more
new  Debentures  of other  authorized  denominations  but of the same  aggregate
principal  amount;  all  subject  to the terms and  conditions  set forth in the
Indenture.

                Subject  to the  provisions  of the  Indenture,  the  registered
holder hereof is entitled,  at his option,  at any time prior to maturity (or if
this Debenture is called for redemption prior to maturity, then to and including
but not after the close of business on the date fixed for such redemption unless
the Company  shall default in making the  redemption  payment when due, in which
case the conversion  right shall  terminate at the close of business on the date
such default is cured and such  Debenture is redeemed) to convert the  principal
hereof (or, in case this Debenture is of a denomination in excess of $1,000, any
portion  hereof  which is $1,000 or an integral  multiple of $1,000)  into fully
paid and nonassessable shares of the Common Stock of the Company, at the initial
conversion  rate of 145.7726  shares of the Common Stock of the Company for each
$1,000  principal  amount of Debentures,  or at the adjusted  Conversion Rate in
effect at the date of conversion  determined as provided in the Indenture,  upon
surrender of this  Debenture  to the Company at its office or agency  maintained
for that purpose in the Borough of Manhattan,  the City of New York, accompanied
(if so required by the Company) by instruments of registration  of transfer,  in
form  satisfactory to the Company,  duly executed by the registered holder or by
his duly authorized  attorney.  If as a result of a Change in Control the holder
exercises its option to require the Company to repurchase this  Debenture,  such
right to convert shall  terminate  upon receipt by the Company of written notice
of  exercise of such option  (unless  the  Company  shall  default in making the
repurchase  payment when due, in which case the conversion right shall terminate
at the close of business on the date such default is cured and such Debenture is
repurchased).  No adjustment is to be made on  conversion  for interest  accrued
hereon or for dividends on Common Stock issued on conversion.

                However, Debentures surrendered for conversion during the period
between the close of business on any interest  payment record date and the close
of business on the corresponding interest payment date (except Debentures called
for redemption on a redemption date) must be accompanied by payment of an amount
equal

                                       7
<PAGE>

to the interest  payment to be received on such interest payment date with
respect to such Debenture presented for conversion. No fractional shares will be
issued  upon any  conversion  but,  subject to the  conditions  provided  in the
Indenture,  the  Company  will  deliver  a check  for the  market  value  of the
fractional share.

                Prior to due  presentment  for  registration  of  transfer,  the
Company,  the Trustee, any paying agent and any Debenture registrar may deem and
treat the registered  holder hereof as the absolute owner hereof (whether or not
this Debenture shall be overdue and  notwithstanding  any notice of ownership or
writing  hereon made by anyone) for the  purpose of  receiving  payment of or on
account of the principal  hereof (and premium,  if any) and interest due hereon,
and for all other  purposes,  and  neither  the  Company nor the Trustee nor any
paying agent nor any Debenture  registrar shall be affected by any notice to the
contrary.

                No recourse  shall be had for the payment of the principal of or
the interest on this Debenture,  or for any claim based hereon,  or otherwise in
respect  hereof,  or based on or in respect of the  Indenture  or any  indenture
supplemental thereto, against any incorporator, stockholder, officer, trustee or
director, past, present or future, as such, of the Company or of any predecessor
or successor corporation, whether by virtue of any constitution, statute or rule
of law or  equity,  or by  the  enforcement  of any  assessment  or  penalty  or
otherwise, all such liability being, by the acceptance hereof and as part of the
consideration  for the issue  hereof,  expressly  waived and  released  by every
holder or owner hereof, as more fully provided in the Indenture.

                All  terms  used in this  Debenture  which  are  defined  in the
Indenture shall have the meanings assigned to them in the Indenture.

(a) The Company may issue the Senior Subordinated Exchange Notes in an aggregate
principal  amount  not to exceed  $25,000,000  in  exchange  for  Debentures  in
accordance with the provisions of Section 3.07. The Senior Subordinated Exchange
Notes will have and be subject  to all of the same  terms and  provisons  as the
Debentures  under this  Indenture and shall be governed by this Indenture to the
extent  permitted  by law except that the  provisions  of Article  Four will not
apply and the Senior  Subordinated  Exchange  Notes will bear a separate rate of
interest   determined  in  accordance  with  the  provisions  of  Section  3.07.
References  to the  Debentures  shall be  deemed  to also  refer  to the  Senior
Subordinated Exchange Notes except with respect to the provisons of Article Four
and the rate of interest.

                (b) Debentures, for not to exceed the aggregate principal amount
of  twenty-five  million  dollars  ($25,000,000),  except as provided in Section
2.07, may, upon the execution of this Indenture or from time to time thereafter,
be executed by the Company and delivered to the Trustee for authentication,  and
the Trustee shall thereupon  authenticate and deliver said Debentures to or upon
the written order of the Company, signed by its Chairman of the Board, President
or a Vice President and by its Treasurer, an Assistant Treasurer,  its Secretary
or an Assistant Secretary, without further action by the Company.

                SECTION 2.02. Form of Debentures and Trustee's Certificate.  The
Debentures and the Trustee's  certificate of  authentication  to be borne by the
Debentures  shall be substantially of the tenor and purport as in this Indenture
above  recited,   and  may  have  such  letters,   numbers  or  other  marks  of
identification  or  designation  and  such  legends  or  endorsements   printed,
lithographed or engraved  thereon as the Company may deem appropriate and as are
not inconsistent with the provisions of this Indenture, or as may be required to
comply with any law or with any rule or regulation made or as may be required to

<PAGE>

pursuant  thereto or with any rule or regulation of any stock  exchange on which
the Debentures may be listed, or to conform to usage.

                SECTION  2.03.  Date  of  Debentures  and   Denominations.   The
Debentures  shall be  issuable  as  registered  Debentures  without  coupons  in
denominations of One Thousand Dollars ($1,000) and integral multiples thereof.

                Except as provided in the next sentence, the Debentures shall be
dated the date of  authentication  and shall bear  interest from the date of the
issuance,  payable  semi-annually on March 30 and September 30, commencing March
30, 1998,  or, if interest to any March 30 or September 30 has been paid or duly
provided  for,  from the  March 30 or  September  30,  as the case may be,  next
preceding the date thereof to which interest has been paid or duly provided for,
unless such date is a date to which interest has been paid or duly provided for,
in which case they shall bear interest from the date thereof.  However,  so long
as there  shall  be no  existing  default  in the  payment  of  interest  on the
Debentures,  each  Debenture  authenticated  after the close of  business on the
record date (as hereinafter  defined) for any interest payment date and prior to
such Interest  Payment Date shall bear interest from such Interest Payment Date;
provided,  however,  that if and to the extent the Company  shall default in the
payment  of the  interest  due on such  Interest  Payment  Date,  then  all such
Debentures  shall bear  interest  from March 30 or September 30, as the case may
be, next  preceding the date of such  Debentures to which interest has been paid
or duly  provided  for, or if no interest has been paid or duly  provided for on
the Debentures,  from the date of  authentication  of the  Debentures.  The term
"record date" as used with respect to a semi-annual  Interest Payment Date shall
mean the March 15 or  September  15,  as the case may be,  next  preceding  such
Interest Payment Date.

                The  person in whose name any  Debenture  is  registered  at the
close of  business  on the record date with  respect to a  semi-annual  Interest
Payment Date shall be entitled to receive the interest  payable on such Interest
Payment  Date  notwithstanding  the  cancellation  of such  Debenture  upon  any
registration of transfer or exchange thereof  subsequent to such record date and
prior to such  Interest  Payment  Date;  provided,  however,  that if and to the
extent the  Company  shall  default in the payment of the  interest  due on such
Interest  Payment Date, such defaulted  interest shall be paid to the persons in
whose names the  Debentures are registered on a record date fixed by the Company
for the  payment of such  defaulted  interest  by notice  given by mail by or on
behalf  of the  Company  to the  holders  of  Debentures  not less  than 15 days
preceding such record date, which record shall be not more than 15 days nor less
than 5 business days before the date for such payment.

                If any Debenture or portion  thereof is called for redemption on
a redemption  date after the close of business on the record date next preceding
any March 30 or  September  30 and before the  opening of business on such March
__, or September 30 and notice of such  redemption has been mailed and funds for
such

                                       17
<PAGE>

redemption have been duly provided, interest accrued to the redemption date
on such  Debenture or portion so called shall be paid only against  surrender of
the Debenture for redemption in accordance with said notice.

                SECTION 2.04. Execution and Authentication of Debentures and Use
of Temporary Debentures. The Debentures shall be signed on behalf of the Company
by, or bear the facsimile signature of, its Chairman of the Board,  President or
a Vice  President,  under its corporate seal attested by the manual or facsimile
signature  of its  Secretary or an Assistant  Secretary or the  Treasurer.  Such
facsimile  signatures may be imprinted or otherwise reproduced on the Debenture.
The Company may adopt and use the signature or facsimile signature of any person
who shall be any such  officer of the  Company at the time of the  execution  of
Debentures,  irrespective of the date as of which the same shall be executed, or
of  any  person  who  shall  have  been  any  such   officer  of  the   Company,
notwithstanding  the fact that at the time the Debentures shall be authenticated
and  delivered  or disposed  of, he shall have ceased to be such  officer of the
Company.  The seal of the Company may be in the form of a facsimile  of the seal
of the Company and may be impressed,  affixed, imprinted or otherwise reproduced
on the Debentures.

                Only such  Debentures  as shall bear  thereon a  certificate  of
authentication  substantially in the form hereinbefore recited,  executed by the
Trustee,  shall be entitled to the  benefits  of this  Indenture  or be valid or
obligatory for any purpose.  Such  certificate by the Trustee upon any Debenture
executed by the Company  shall be  conclusive  evidence  that the  Debenture  so
authenticated  has been  duly  authenticated  hereunder  and that the  holder is
entitled to the benefits of this Indenture.

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

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

              SECTION 2.05. Exchange, Registration and Transfer of Debentures.
The Company shall keep at the Corporate  Trust Office or agency to be maintained
by the Company as provided in Section 5.02 a register in which,  subject to such
reasonable regulations as it may prescribe,  it will register all Debentures and
upon surrender of any Debenture for  registration  of transfer at such office or
agency,   the  Company   shall  execute  and  register  and  the  Trustee  shall
authenticate  and deliver in the name of the  transferee  or  transferees  a new
Debenture or Debentures for a like aggregate  principal  amount of Debentures of
any authorized denominations.

                Unless  and  until  otherwise   determined  by  the  Company  by
resolution of its Board of Directors, the register of the Company in the Borough
of  Manhattan,  City and State of New York,  for the  purpose  of  registration,
exchange or  registration  of transfer  of the  Debentures  shall be kept at the
Corporate  Trust  Office of the Trustee and,  for this  purpose,  the Trustee is
hereby initially designated "Debenture Registrar".

                The several  authorized  denominations  of  Debentures  shall be
interchangeable in equal aggregate principal amounts. Debentures to be exchanged
shall be surrendered at the office or agency to be maintained by the Company for
the  purpose as  provided  in Section  5.02 and the  Company  shall  execute and
register the transfer thereof and the Trustee shall  authenticate and deliver in
exchange therefor the Debenture or Debentures which the  Debentureholder  making
the exchange shall be entitled to receive, bearing numbers not contemporaneously
outstanding.

                All Debentures  presented or  surrendered  for  registration  of
transfer, exchange,  redemption,  conversion or payment shall (if so required by
the Company or the Trustee) be duly  endorsed by, or be  accompanied  by written
instrument or  instruments of transfer in form  satisfactory  to the Company and
the  Trustee  duly  executed  by, the  registered  holder or his  attorney  duly
authorized in writing.

                For any exchange or  registration  of transfer or  conversion or
redemption of Debentures, the Company, at its option, may require the payment of
a sum sufficient to reimburse it for any tax or other  governmental  charge that
may be imposed in relation thereto. No service charge shall be made for any such
transaction.

                SECTION  2.06.  When Company Not  Required To Make  Transfers or
Exchanges.  The Company  shall not be required  to register  the  transfer of or
exchange  Debentures  for a period of l5 days next  preceding  any  selection of
Debentures to be redeemed,  nor shall it be required to register the transfer of
or exchange  any  Debentures  or  portions  thereof  called or being  called for
redemption  in whole or in part  except,  in the  case of any  Debentures  to be
redeemed in part, the portion thereof not so to be redeemed.

                SECTION 2.07. Mutilated,  Destroyed,  Lost or Stolen Debentures.
In case any Debenture  shall become  mutilated or be destroyed,  lost or stolen,
the  Company in its  discretion  may  execute,  and upon its request the Trustee
shall

                                       19
<PAGE>

authenticate and deliver, a new Debenture of like tenor,  bearing a number
not  contemporaneously  outstanding  and such notation as may be required by the
rules  and  regulations  of any  national  securities  exchange  upon  which the
Debentures  are, or are to be,  listed,  in exchange  and  substitution  for the
mutilated  Debenture  or in lieu of and in  substitution  for the  Debenture  so
destroyed,  lost or  stolen.  In every  case  the  applicant  for a  substituted
Debenture  shall  furnish to the  Company and to the  Trustee  such  security or
indemnity  or both as may be  required  by them to save  each of them,  and,  if
requested,  any paying agents and Debenture Registrars of the Company,  harmless
from all risk,  however  remote,  and the  applicant  shall also  furnish to the
Company and to the Trustee  evidence to their  satisfaction  of the  mutilation,
destruction,  loss or theft of the  applicant's  Debenture  and of the ownership
thereof.  Subject to its receipt of such  security or  indemnity  or both and of
such evidence, the Trustee shall authenticate any such substituted Debenture and
deliver the same upon the written request or authorization of any officer of the
Company.  Upon the issue of any substituted  Debenture,  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
counsel  fees,  of the Company,  the Trustee,  and any paying agent or Debenture
Registrar,  connected  therewith.  In case any Debenture which has matured or is
about to mature shall  become  mutilated or be  destroyed,  lost or stolen,  the
Company may,  instead of issuing a substitute  Debenture,  pay or authorize  the
payment of the same (without surrender thereof except in the case of a mutilated
Debenture) if the applicant for such payment shall furnish to the Company and to
the Trustee  such  security or indemnity as may be required by them to save each
of them  harmless,  and  evidence  to the  satisfaction  of the  Company and the
Trustee of the mutilation,  destruction,  loss or theft of such Debenture and of
the ownership thereof.

                Every  Debenture  issued  pursuant  to the  provisions  of  this
Section  in  substitution  for any  Debenture  which  is  alleged  to have  been
destroyed,  lost or stolen shall constitute an additional contractual obligation
of the Company, whether or not the destroyed,  lost or stolen Debenture shall be
found at any time, or be enforceable by anyone,  and such new Debenture shall be
entitled to all the benefits of this Indenture equally and proportionately  with
any and all other Debentures duly issued hereunder. All Debentures shall be held
and owned upon the express condition that the foregoing provisions are exclusive
with respect to the  replacement,  or payment of mutilated,  destroyed,  lost or
stolen  Debentures  and shall  preclude  any and all other  rights or  remedies,
notwithstanding  any law or  statute  existing  or  hereinafter  enacted  to the
contrary with respect to the replacement,  or payment of negotiable  instruments
or other securities without their surrender.

                SECTION  2.08.  Cancellation  of  Surrendered  Debentures.   All
Debentures  surrendered  for the  purpose of  payment,  redemption,  conversion,
exchange or registration of transfer shall be delivered to the Trustee and shall
be canceled by it, and no Debentures  shall be issued in lieu thereof  except as
expressly  required or permitted  by any of the  provisions  of this  Indenture.
Unless otherwise  directed by the

                                       20
<PAGE>

Company,  the Trustee shall cremate or destroy by shredding canceled  Debentures
and deliver a certificate  thereof to the Company.  If the Company shall acquire
any of the  Debentures,  such  acquisition  shall not operate as a redemption or
satisfaction of the indebtedness represented by such Debentures unless and until
the same are  delivered  to the Trustee,  or  surrendered  to the  Trustee,  for
cancellation.

                SECTION 2.09. Debentureholders and Senior Indebtedness.  Nothing
in this Indenture or in the Debentures,  expressed or implied,  shall give or be
construed  to give to any person,  firm or  corporation,  other than the parties
hereto and the holders of the Debentures  and, to the extent provided in Article
Thirteen,  the holders of Senior  Indebtedness,  any legal or  equitable  right,
remedy or claim under or in respect of this  Indenture,  or under any  covenant,
condition or provision herein  contained,  all of the covenants,  conditions and
provisions  herein being for the sole  benefit of the parties  hereto and of the
holders of the Debentures  and, to the extent  aforesaid,  the holders of Senior
Indebtedness.

                  SECTION 2.10. Persons Deemed Owners.  Prior to due presentment
of Debentures for  registration of transfer,  the Company or the Trustee and any
agent of the  Company  or the  Trustee  may treat the  person in whose name such
Debentures  are  registered  as the  owner of such  Debentures  for  purpose  of
receiving  payment of principal  of, and (subject to Section  2.05)  interest on
such  Debentures  and for all other  purposes  whatsoever,  whether  or not such
Debentures  are 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 2.11. CUSIP Numbers. The Company in issuing Debentures
shall use  "CUSIP"  numbers  (if then  generally  in use) in  addition to serial
numbers; if so, the Trustee shall use such "CUSIP" numbers in addition to serial
numbers in notice of redemption  and  repurchase  as a  convenience  to holders;
provided that any such notice may state that no representation is made as to the
correctness  of such CUSIP  numbers  either as printed on the  Debentures  or as
contained in any notice of a redemption or  repurchase  and that reliance may be
placed  only on the  serial  or  other  identification  numbers  printed  on the
Debentures,  and any such redemption or repurchase  shall not be affected by any
defect in or omission of such CUSIP numbers.

                SECTION  2.12.  Global   Securities.   The  Debentures,   unless
registered under the Securities Act of 1933, as amended ("Securities Act") shall
be issued  initially in the form of one or more "Restricted  Global  Securities"
The Depositary or its nominee shall be the holder of the Global Securities,  and
owners  of  beneficial  interests  in the  Security  represented  by the  Global
Securities shall hold such interests pursuant to the procedures and practices of
the  Depositary.  Any such owner's  beneficial  ownership of any such Debentures
will be shown only on, and the  transfer  of such  ownership  interest  shall be
effected only  through,  records  maintained  by the  Depositary or its nominee.
Transfer of interests in a Global Security shall be subject to the

                                       21
<PAGE>

provisions of Section 2.05. All interests in a Global Security may be subject to
the procedures and requirements of the Depositary.

         Unless the  Depositary  notifies  the Company  that it is  unwilling or
unable  to  continue  as  depositary  for a Global  Security  or  ceases to be a
"Clearing  Agency"  registered  under  the  Securities   Exchange  Act  of  1934
("Exchange Act") or announces an intention permanently to cease business or does
in fact do so and a successor  Depositary is not appointed by the Company within
90 days of such notice, owners of beneficial interests in a Global Security will
not be entitled to have any portions of such Global Security registered in their
names,  will  not  receive  or be  entitled  to  receive  physical  delivery  of
Securities in definitive  form and will not be considered  the owners or holders
of the Global Security.  Any Global Security exchanged upon the occurrence of an
event described in the preceding sentence shall be so exchanged in whole and not
in part.  Any Security  issued in exchange for a Global  Security or any portion
thereof  shall be a Global  Security,  provided that any such Security so issued
that is  registered  in the name of a Person  other  than  the  Depositary  or a
nominee thereof shall not be a Global Security.

         Securities  issued in  exchange  for a Global  Security  or any portion
thereof pursuant to the preceding paragraph above shall be issued in definitive,
fully  registered  form,  without  interest  coupons,  shall  have an  aggregate
principal  amount equal to that of such Global Security or portion thereof to be
so  exchanged,  shall be  registered  in such  names  and be in such  authorized
denominations  as the  Depositary  shall  designate  and shall bear any  legends
required  hereunder.  Any Global  Security  to be  exchanged  in whole  shall be
surrendered  by the  Depositary  to the Trustee,  as Debenture  Registrar.  With
regard to any Global  Security  to be  exchanged  in part,  either  such  Global
Security  shall be so  surrendered  for exchange or, if the Trustee is acting as
custodian  for the  Depositary  or its  nominee  with  respect  to  such  Global
Security,  the principal amount thereof shall be reduced,  by an amount equal to
the portion  thereof to be so exchanged,  by means of an appropriate  adjustment
made on the records of the Trustee.  Upon any such surrender or adjustment,  the
Trustee shall authenticate and deliver the Security issuable on such exchange to
or upon the order of the Depositary or an authorized  representative thereof. In
the event of the  occurrence  of any of the events  specified  in the  preceding
paragraph,  the Company will promptly make available to the Trustee a reasonable
supply of certificated Securities in definitive form.

         Except as otherwise  set forth in the  Indenture or a Global  Security,
owners of beneficial  interests in the Securities evidenced by a Global Security
will not be  entitled to any rights  under the  Indenture  with  respect to such
Global  Security,  and the  Depositary  or its  nominee  may be  treated  by the
Company,  the  Trustee  and any agent of the Company or the Trustee as the owner
and Holder of such Global Security for all purposes whatsoever.  Notwithstanding
the foregoing, nothing herein shall prevent the Company, the Trustee or any such
agent  from  giving  effect  to  any  written  certification,   proxy  or  other
authorization  furnished by the Depositary or its nominee or impair,  as between
the  Depositary  or its  nominee and such owners of  beneficial  interests,  the

                                       22
<PAGE>

operation of  customary  practices  governing  the exercise of the rights of the
Depositary or its nominee as Holder of any Security.

         The Depositary shall be a clearing agency registered under the Exchange
Act.  Initially,  any and all Global Securities issued hereunder shall be issued
to the  Depositary,  registered  in the name of Cede & Co. as the nominee of the
Depositary,  and deposited  with the Trustee,  as custodian  for The  Depositary
Trust Company.

                            REDEMPTION OF DEBENTURES

                SECTION 3.01. Debentures  Redeemable.  Subject to the provisions
of  Article  Thirteen  hereof,  the  Company  may,  at its  option,  redeem  the
Debentures,  in whole or in part,  at any time on and after  September 30, 2000,
and prior to maturity, on not less than 30 nor more than 60 days' notice to each
Debentureholder,  at the  redemption  prices  (expressed as  percentages  of the
principal amount thereof to be redeemed) set forth in the tabulation in the form
of Debenture  provided for herein,  in each case,  with accrued  interest to the
date of  redemption  (but if the date  fixed  for  redemption  is a  semi-annual
interest  payment  date,  the interest  installment  payable on such date shall,
subject to Section  2.03,  be paid to the holder at the close of business on the
preceding  record  date),  provided,  however,  that the  Debentures  may not be
redeemed on or after  September  30, 2000 and prior to September 30, 2001 unless
the  Closing  Price of the  Common  Stock has  equaled or  exceeded  l50% of the
Conversion Price per share then in effect for at least 20 trading days within 30
consecutive  trading  days ending  within  five  trading  days before  notice of
redemption is mailed.

                SECTION 3.02.  Notice of  Redemption.  In case the Company shall
desire to  exercise  such right to redeem all or any part of the  Debentures  in
accordance  with the  right  reserved  so to do,  it shall  give  notice of such
redemption  to holders of the  Debentures  to be redeemed in whole or in part as
hereinafter in this Section provided.

                Notice  of  redemption  to  the  holders  of  Debentures  to  be
redeemed,  in whole or in part,  shall be given by mailing,  first class postage
prepaid,  a notice of such  redemption  not later than on the thirtieth day, and
not earlier than on the sixtieth  day,  before the date fixed for  redemption to
such holders at their last addresses as they shall appear upon the  registration
books.  Any  notice  which is  mailed in the  manner  herein  provided  shall be
conclusively  presumed  to have been duly given,  whether or not the  registered
holder receives the notice. In any case, failure duly to give notice by mail, or
any  defect  in the  notice  to the  holder  of any  Debentures  designated  for
redemption in whole or in part, shall not affect the validity of the proceedings
for the redemption of any other Debentures.

<PAGE>

                Each such notice of redemption  shall specify the date fixed for
redemption and the redemption price at which Debentures are to be redeemed,  and
shall  specify  where  payment  of the  redemption  price  is to be  made,  upon
presentation  and  surrender of such  Debentures,  and shall state that interest
accrued  to the date  fixed for  redemption  will be paid as  specified  in said
notice, and that from and after said date interest thereon will cease to accrue.
Such notice shall also state the current  Conversion Price and the date on which
the right to convert such Debentures or portions  thereof into Common Stock will
terminate.  In case any  Debenture  is to be redeemed  in part only,  the notice
shall state the portion of the principal  amount  thereof to be redeemed  (which
shall be $1,000 or an  integral  multiple of $1,000) and shall state that on and
after the redemption date, upon surrender of such Debenture,  a new Debenture or
Debentures in principal  amount equal to the unredeemed  portion thereof will be
issued.

                If less than all the Debentures are to be redeemed,  the Company
shall give the Trustee 45 days prior written  notice,  or such shorter notice as
may be acceptable to the Trustee,  in advance of the  redemption  date as to the
aggregate  principal  amount of  Debentures  to be redeemed,  and  thereupon the
Trustee  shall  select  the  particular  Debentures  or parts  thereof  so to be
redeemed by lot,  pro rata,  or  according  to such other  method as the Trustee
shall deem proper in its discretion  and shall  thereafter  promptly  notify the
Company in writing of the numbers of the Debentures (or portions  thereof) to be
redeemed provided that no Debentures shall be redeemed; in part in amounts other
than $1,000 or integral  multiples  thereof.  For the purpose of determining the
Debentures  to be  redeemed,  the  Trustee  need not  treat as  outstanding  any
Debentures authenticated within l5 days prior to its selection.

                SECTION 3.03.  Debentures Called for Redemption Due and Payable.
If the giving of notice of redemption  shall have been  completed as provided in
Section 3.02, the Debentures or portions of Debentures  specified in such notice
shall  become due and payable on the date and at the place stated in such notice
at the applicable  redemption price,  together with interest accrued to the date
fixed for  redemption,  and on and after  such date of  redemption  (unless  the
Company shall default in the payment of such  Debentures or portions  thereof at
the redemption  price,  together with interest accrued thereon to the date fixed
for  redemption)  interest on the Debentures or portions of Debentures so called
for  redemption  shall cease to accrue.  On  presentation  and surrender of such
Debentures  on or after  said  date at said  place  of  payment  in said  notice
specified,  the said Debentures shall be paid and redeemed by the Company at the
applicable  redemption price, together with interest accrued thereon to the date
fixed for redemption.

                SECTION  3.04.  Deposit of Redemption  Moneys.  Anything in this
Indenture contained to the contrary notwithstanding, if the giving of the notice
of redemption  shall have been completed as provided in Section 3.02, and if the
Company shall have  deposited in trust with the Trustee funds (to be immediately
available for payment) sufficient to redeem the Debentures to be redeemed on the
date fixed for

                                       24

<PAGE>

redemption,  at the applicable  redemption price, together with interest accrued
to the date fixed for redemption, then all obligations of the Company in respect
of such  Debentures  shall cease and be discharged and subject to the provisions
of  Article  Fourteen,  the  holders  of such  Debentures  shall  thereafter  be
restricted exclusively to such funds for any and all claims of whatsoever nature
on their part under this Indenture, or in respect of such Debentures.

                SECTION  3.05.   Redemption  in  Part.  Upon   presentation  and
surrender  of any  Debenture  which is to be redeemed in part only,  the Company
shall  execute  and the  Trustee  shall  authenticate  and deliver to the holder
thereof,  at the  expense of the  Company,  a new  Debenture  or  Debentures  of
authorized  denominations in principal amount equal to the unredeemed portion of
the Debenture so presented.


                  SECTION 3.06. Redemption Following Change in Control. (a) Each
holder of  Debentures  shall have the right,  as provided in this Section  3.06,
upon a Change in Control (as defined in this Section  3.06),  subject to certain
conditions  and  restrictions,  to require the Company to  repurchase  and, upon
exercise of such holder's  right,  the Company shall  repurchase all or any part
(in integral  multiples of $1,000) of their  Debentures at a repurchase price of
100% of the principal amount thereof,  plus accrued and unpaid interest, if any,
to the Repurchase Date (as defined herein),  in cash. The Company shall have the
right to satisfy  such  repurchase  obligation  by the  issuance and delivery of
shares of its Common  Stock  valued at the Market  Price (as defined  herein) in
exchange for certificates evidencing the Debentures.


                  (b) The term  "Change in Control" as used in this Section 3.06
means the  occurrence of any of the following  events after the date of original
issuance of the Debentures: (i) any person (including any entity or group deemed
to be a "person" under Section 13(d)(3) or Section 14(d)(2) of the Exchange Act)
becomes the direct or indirect  beneficial  owner (as  determined  in accordance
with Rule 13d-3 under the Exchange Act) of shares of the Company's capital stock
representing greater than 50% of the total voting power of all shares of capital
stock  of the  Company  entitled  to vote in the  election  of  Directors  under
ordinary  circumstances  or to elect a majority of the Board of Directors of the
Company,  (ii) the Company  sells,  transfers  or  otherwise  disposes of all or
substantially all of the assets of the Company, (iii) when, during any period of
12  consecutive  months after the date of original  issuance of the  Debentures,
individuals  who at the beginning of any such 12-month  period  constituted  the
Board  of  Directors  of the  Company  (together  with any new  directors  whose
election by such Board or whose  nomination for election by the  stockholders of
the Company  was  approved  by a vote of a majority  of the  directors  still in
office  who were  either  directors  at the  beginning  of such  period or whose
election or nomination for election was  previously so approved),  cease for any
reason to constitute a majority of the Board of Directors of the Company then in
office  (excluding from such calculation any election of directors by holders of
Convertible  Exchangeable Preferred Stock), or (iv) the date of the consummation
of the merger or  consolidation  of the Company  with

                                       25
<PAGE>

another Person where the  stockholders of the Company  immediately  prior to the
merger or consolidation would not beneficially own, immediately after the merger
or consolidation, shares entitling such stockholders to 50% or more of all votes
(without consideration of the rights of any class of stock to elect directors by
a separate class vote) to which all  stockholders  of the Person issuing cash or
securities in the merger or  consolidation  would be entitled in the election of
directors, or where members of the Board of Directors of the Company immediately
prior to the merger or consolidation, would not, immediately after the merger or
consolidation,  constitute  a majority of the board of  directors of the Company
issuing cash or securities in the merger or consolidation.

                  (c) Each holder of Debentures  shall have the right  effective
for 30 days following the receipt of a notice  disclosing such Change in Control
(the "Repurchase  Right Notice") to require the Company to repurchase all or any
part (in integral multiples of $1,000) of such holder's Debentures,  on the date
(the  "Repurchase  Date")  that is no later  than 45 days  after the date of the
Repurchase  Right Notice,  at a repurchase  price equal to 100% of the principal
amount  thereof,  plus accrued and unpaid  interest to the Repurchase  Date with
respect to such  Debentures.  On or before the 30th day  following any Change in
Control,  the  Company,  or at the request of the Company,  the transfer  agent,
shall  mail  the  Repurchase  Right  Notice  to each  holder  of  record  of the
Debentures  stating  (i) that a Change in  Control  has  occurred  and that such
holder  has the  right to  require  the  Company  to  repurchase  such  holder's
Debentures, (ii) the Repurchase Date, (iii) the date by which the right to cause
repurchase  must be exercised,  (iv) the price at which such repurchase is to be
made, if the right to cause repurchase is exercised and (v) a description of the
procedure which such holder must follow to exercise a right to cause  repurchase
and whether or not the Company presently intends to deliver shares of its Common
Stock in  payment  therefor.  No failure  of the  Company to give the  foregoing
notice shall limit any such holder's  right to exercise a repurchase  right.  To
exercise the repurchase  right,  on or before the 30th day after the date of the
Repurchase  Right Notice,  holders of Debentures  must deliver written notice to
the Company (or an agent  designated  by the Company for such  purposes)  of the
holder's  exercise  of such  right,  together  with  the  certificate  for  such
Debentures with respect to which the right is being exercised, duly endorsed for
transfer.  Such  written  notice  shall be  irrevocable  except with  respect to
conversions  permitted  prior to the Repurchase  Date. If the Repurchase Date is
between  a  regular  record  date  for the  payment  of  interest  and the  next
succeeding  Interest  Payment Date,  any  Debentures to be  repurchased  must be
accompanied by payment of an amount equal to the interest,  payable on such next
succeeding  Interest Payment Date on the amount to be repurchased,  and interest
will be paid on such next  succeeding  Interest  Payment Date to the  registered
holder of such Debentures on the immediately  preceding record date.  Debentures
repurchased on an Interest  Payment Date need not be accompanied by any payment,
and the interest on Debentures  being  repurchased will be paid on such Interest
Payment Date to the registered  holder of such  Debentures on the  corresponding
record date.  The Company  shall have 10 days from  receipt of such

                                       26


<PAGE>

exercise to notify the holder  whether the  Company  will redeem the  Debentures
and/or  deliver  shares  of  Common  Stock in  satisfaction  of its  obligations
hereunder.

SECTION 3.07.  Redemption at Option of Holders.  Each holder of Debentures shall
have the right  ("Put  Repurchase  Right")  effective  during  the day 30 period
commencing September 30, 2000, to give the Company a notice (the "Put Repurchase
Right Notice") to require the Company to repurchase all or any part (in integral
multiples  of  $1,000)  of such  holder's  Debentures,  on the  date  (the  "Put
Repurchase  Date") that is no later than 15 days after the expiration of such 30
day period  for  providing  the Put  Repurchase  Right  Notice,  either,  at the
Company's  option,  in cash at a repurchase price equal to 100% of the principal
amount thereof, plus accrued and unpaid interest to the Put Repurchase Date with
respect to such  repurchased  Debentures or in exchange for Senior  Subordinated
Exchange  Notes as described  below.  To exercise the Put  Repurchase  Right,  a
holder of Debentures must deliver the Put Repurchase Right Notice to the Company
(or an agent  designated  by the  Company  for such  purposes)  of the  holder's
exercise of such Put Repurchase  Right,  together with the  certificate for such
Debentures  with respect to which the Put Repurchase  Right is being  exercised,
duly  endorsed to the Company for  transfer,  with  signature  guaranteed to the
reasonable  satisfaction  of the  Company or its said  agent.  Such  written Put
Repurchase Right Notice shall be irrevocable from and after the date of such Put
Repurchase Right Notice.  If the Put Repurchase Date is between a regular record
date for the payment of interest and the next succeeding  Interest Payment Date,
any  Debentures to be  repurchased  must be  accompanied by payment of an amount
equal to the interest,  payable on such next succeeding Interest Payment Date on
the amount to be repurchased,  and interest will be paid on such next succeeding
Interest  Payment  Date  to the  registered  holder  of such  Debentures  on the
immediately preceding record date. Debentures repurchased on an Interest Payment
Date need not be  accompanied  by any payment,  and the  interest on  Debentures
being  repurchased  will be paid on such Interest Payment Date to the registered
holder of such  Debentures on the  corresponding  record date. The Company shall
have 10 days from receipt of such Put  Repurchase  Right  Notice,  to notify the
holder of the Debentures with respect to which such Put Repurchase  Right Notice
was given,  whether  the  Company  will  redeem the  Debentures  for cash and/or
deliver to such holder Senior Subordinated Notes due 2002 ("Senior  Subordinated
Exchange Note(s)"), in satisfaction of the Company's obligations with respect to
the Put  Repurchase  Right of such  holder  under this  Section  3.07,  for such
Debentures.  Failure of the Company to duly give  notice to such  holder  within
such 10 day period shall not affect the Company's  obligation to repurchase  the
Debentures  in  accordance  with the terms of this Section 3.07 or the Company's
right to elect to repurchase the Debentures for either,  at its option,  cash or
Senior Subordinated Exchange Notes as set forth herein. Such Senior Subordinated
Exchange Notes will be subordinated  to the same extent as the Debentures,  rank
pari passu with the  Debentures  and will be governed by this  Indenture  to the
extent  permitted by law and will have all the same terms and  conditions as the
Debentures including the same subordination provisions,  maturity date, Interest
Payment Date and Interest  Record Date, but will not 

                                       27
<PAGE>

be convertible into Common Stock of the Company and will bear a separate rate of
interest. The Senior Subordinated Exchange Notes will bear interest at a rate in
order for the Senior Subordinated  Exchange Notes to have a market value of 100%
of  their  principal  amount  on the  Put  Repurchase  Date as  determined  by a
nationally  recognized investment banking firm chosen by the Company (which rate
shall in no event be  greater  than the rate  permitted  by law),  provided  the
interest rate on the Senior Subordinated Exchange Notes shall not exceed 14% per
annum. As soon as such interest rate is determined,  the Company and the Trustee
will  execute  a  supplement  to  this  Indenture,  as may be  required  by law,
governing such issuance of the Senior Subordinated Exchange Notes.


                                  ARTICLE FOUR

                            CONVERSION OF DEBENTURES

                SECTION 4.01. Conversion Privilege and Conversion Price. Subject
to and upon  compliance  with the provisions of this Article Four, at the option
of the holder,  any  Debenture,  or any portion of the principal  amount thereof
which is $1,000 or an integral multiple of $1,000, may, at any time during usual
business  hours prior to  September  30, 2002 (or if such  Debenture  or portion
thereof is called for redemption prior to September 30, 2002, then in respect of
such  Debenture or portion  thereof to and  including but not after the close of
business on the date fixed for such redemption  unless the Company shall default
in making the redemption  payment when due, in which case the  conversion  right
shall  terminate  at the close of business on the date such default is cured and
such  Debenture is  redeemed),  be converted  into fully paid and  nonassessable
shares of Common Stock of the Company at the equivalent  Conversion Rate then in
effect. If as a result of a Change in Control the holder exercises its option to
require the Company to  repurchase  the  Debenture,  such right to convert shall
terminate  upon  receipt by the  Company of written  notice of  exercise of such
option unless the Company shall  default in making the  repurchase  payment when
due, in which case the conversion right shall terminate at the close of business
on the date  such  default  is cured  and such  Debenture  is  repurchased.  The
Conversion  Rate shall be adjusted in certain  instances  as provided in Section
4.04.  The price at which the  Company's  Common Stock shall be  delivered  upon
conversion  shall be  initially  U.S.  $6.86  per  share of  Common  Stock.  The
Conversion  Price shall be adjusted in certain  instances as provided in Section
4.04.

                SECTION  4.02.  Manner of Exercise of Conversion  Privilege.  In
order to exercise the  conversion  privilege,  the holder of any Debenture to be
converted  shall  surrender  such  Debenture  at  any  office  or  agency  to be
maintained by the Company for that purpose  pursuant to Section 5.02,  and shall
give  written  notice to the  Company at such  office or agency  that the holder
elects to convert such  Debenture or a specified  portion  thereof.  Such notice
shall also state the name or names (with  address) in which

                                       28
<PAGE>
the  certificate  or  certificates  for shares of Common  Stock  which  shall be
issuable on such  conversion  shall be issued.  Each Debenture  surrendered  for
conversion  shall,  unless the shares issuable on conversion are to be issued in
the  same  name  as the  registration  of  such  Debenture,  be  accompanied  by
instruments of transfer,  in form  satisfactory  to the Company and the Trustee,
duly  executed  by the holder or his duly  authorized  attorney.  As promptly as
practicable after the receipt of such notice and the surrender of such Debenture
as aforesaid, the Company shall issue and shall deliver at such office or agency
to such holder,  or on his written order, a certificate or certificates  for the
number of full shares  issuable upon the conversion of such Debenture or portion
thereof  in  accordance  with  the  provisions  of  this  Article  Four  and any
fractional  interest  in respect of a share of Common  Stock  arising  upon such
conversion  shall be settled as  provided  in Section  4.03.  In the case of any
Debenture  which is converted in part only,  the Company  shall  execute and the
Trustee shall  authenticate  and deliver to the holder thereof,  without service
charge,  a new  Debenture  or  Debentures  as  requested  by such  holder  in an
aggregate  principal amount equal to the unconverted portion of the principal of
such  Debenture.  Each  conversion  shall be deemed to have been effected on the
date on which  such  notice  shall  have been  received  by the  Company  or its
conversion  agent and such Debenture  shall have been  surrendered as aforesaid,
and the person or persons in whose name or names any certificate or certificates
for shares of Common  Stock  shall be  issuable  upon such  conversion  shall be
deemed to have become on said date the holder or holders of record of the shares
represented  thereby;  provided,  however,  that if the  transfer  books  of the
Company for Common Stock shall be closed on said date,  the Company shall not be
required  to issue any  shares on such  conversion  until the date on which such
transfer  books shall be reopened and such person or persons shall not be deemed
to have become the holder or holders of record of such shares  until the date on
which such  transfer  books  shall be  reopened,  but such  conversion  shall be
nevertheless  be  effected  when such  transfer  books  shall be reopened at the
Conversion  Rate  in  effect  on and  otherwise  as of the  date on  which  such
Debenture shall have been surrendered to and such notice received by the Company
as aforesaid.  The Company  covenants and agrees that its books for the transfer
of Common Stock shall not be closed  during any period  which  includes a record
date for a dividend or other distribution on Common Stock.  However,  Debentures
surrendered  for  conversion  during the period between the close of business on
any Interest Payment Record Date and the close of business on the  corresponding
Interest Payment Date (except  Debentures  called for redemption on a redemption
date) must be accompanied by payment of an amount equal to the interest  payment
to be received on such  Interest  Payment Date with  respect to such  Debentures
presented for conversion.  Subject to the aforesaid requirement for a payment in
the event of  conversion  after the close of  business on the  Interest  Payment
Record Date next preceding an Interest Payment Date, no adjustment shall be made
for interest  accrued on any Debenture  that shall be converted or for dividends
on any Common Stock that shall be issued upon the  conversion of such  Debenture
as provided in this Article Four.

                                       29

<PAGE>
                SECTION 4.03.  Fractional Shares. No fractional shares of Common
Stock shall be issued upon conversions of Debentures. If more than one Debenture
shall be surrendered  for conversion at one time by the same holder,  the number
of full shares which shall be issuable upon conversion  shall be computed on the
basis of the aggregate principal amount of the Debentures (or specified portions
thereof  to  the  extent  permitted  hereby)  so  surrendered.  Instead  of  any
fractional  share of  Common  Stock  which  would  otherwise  be  issuable  upon
conversion  of  any  Debenture  or  Debentures,  the  Company  shall  pay a cash
adjustment  (calculated  to the  nearest  cent) in  respect  of such  fractional
interest in an amount equal to the Closing Price of such fractional  interest on
the trading day  immediately  preceding  the date upon which such  Debenture  or
Debentures are surrendered for conversion. The Closing Price of the Common Stock
on any  trading day shall be computed on the basis of the last sale price of the
Common Stock as shown on the  Composite  Tape of the New York Stock  Exchange on
such trading day, or, if there be no such sale price on such day, the average of
the closing bid and asked prices per share of the Common Stock on such  Exchange
on such  trading  day. If the Common Stock is not at the time listed or admitted
to trading on such  Exchange,  such  Closing  Price  shall be the average of the
closing  bid and asked  prices on such  trading  day on the  principal  national
securities  exchange on which the Common Stock is listed or admitted to trading,
or, if the Common  Stock is not listed or  admitted  to trading on any  national
securities  exchange,  the average of the  closing bid and asked  prices on such
trading day as furnished  by any New York Stock  Exchange  member firm  selected
from time to time by the Board of  Directors  of the  Company  for such  purpose
(other than the Company or a subsidiary thereof).


                  SECTION 4.04.  Adjustment of Conversion Rate and Conversion 
Price. The conversion rate shall be adjusted from time to time as follows:

                  (a) In case the  Company  shall,  at any time or from  time to
         time while any  Debentures  are  outstanding,  (i) issue  shares of its
         Common Stock as a dividend or  distribution  on the Common Stock,  (ii)
         subdivide its outstanding  shares of Common Stock, or (iii) combine its
         outstanding shares of Common Stock into a smaller number of shares, the
         conversion price and the conversion rate in effect immediately prior to
         such  action  shall be  adjusted  so that the holder of any  Debentures
         thereafter  surrendered for conversion shall be entitled to receive the
         number of shares of capital  stock of the  Company  which  such  holder
         would have owned or have been entitled to receive immediately following
         such  action  had such  Debentures  been  converted  immediately  prior
         thereto.  An  adjustment  made  pursuant to this Section  4.04(a) shall
         become  effective  retroactively  to  immediately  after the opening of
         business  on the  day  following  the  record  date  in the  case of an
         issuance and shall become  effective  immediately  after the opening of
         business  on the day  following  the  effective  date in the  case of a
         subdivision 
                                       30
<PAGE>
         or  combination.  If, as a result of an adjustment made pursuant to 
         this Section 4.04(a),  the holder of any  Debentures  thereafter  
         surrendered  for conversionshall become  entitled to receive shares of
         two or more classes of capital stock of the Company, the Board of
         Directors (whose determination shall be conclusive) shall  determine
         the  allocation  of  the  adjusted   Conversion  Price  and/or 
         Conversion Rate between or among shares of such classes of capital 
         stock.

                  (b) In case the  Company  shall,  at any time or from  time to
         time  while any of the  Debentures  are  outstanding,  issue  rights or
         options  or  warrants  to all  holders  of shares of its  Common  Stock
         entitling  them to subscribe for or acquire  shares of Common Stock (or
         securities  convertible  into or  exchangeable  for Common  Stock) at a
         price per share less than the current  market price per share of Common
         Stock  (as  defined  in  Section  4.04(d),  at such  record  date,  the
         Conversion  Rate  shall be  adjusted  so that it shall  equal  the rate
         determined by  multiplying  the Conversion  Rate in effect  immediately
         prior to the date of issuance of such rights or warrants by a fraction,
         the  numerator  of which shall be the number of shares of Common  Stock
         outstanding  on the  date of  issuance  of  such  rights,  options,  or
         warrants plus the number of  additional  shares of Common Stock offered
         for subscription or purchase, and the denominator of which shall be the
         number of shares of Common Stock outstanding on the date of issuance of
         such rights or warrants  plus the number of shares which the  aggregate
         offering  price of the total number of shares so offered would purchase
         at such current Market Price. For the purposes of this Section 4.04(b),
         the  issuance  of  rights,  options or  warrants  to  subscribe  for or
         purchase securities convertible into Common Stock shall be deemed to be
         the  issuance of rights or  warrants  to  purchase  the share of Common
         Stock  into which  such  securities  are  convertible  at an  aggregate
         offering price equal to the aggregate offering price of such securities
         plus the minimum  aggregate  amount (if any) payable upon conversion of
         such securities into shares of Common Stock; provided, however, that if
         all of the shares of Common Stock  subject to such  rights,  options or
         warrants  have not been  issued when such  rights,  options or warrants
         expire,  then the Conversion  Price shall promptly be readjusted to the
         Conversion  Price which would then be in effect had the adjustment upon
         the issuance of such rights, options or warrants been made on the basis
         of the actual number of shares of Common Stock issued upon the exercise
         of such rights,  options or warrants.  An  adjustment  made pursuant to
         this Section 4.04(b) shall become effective  retroactively  immediately
         after the record date for the determination of stockholders entitled to
         receive such rights, options or warrants.

                (c) In case the  Company  shall,  at any time or from  time to
         time while any of the  Debentures  are  outstanding,  distribute to all
         holders of shares of its Common Stock evidences of its  indebtedness or
         securities  or  assets   (excluding  cash  dividends   payable  out  of
         consolidated  earnings or retained  earnings  or  dividends  payable in
         shares of Common Stock) or rights, options or warrants to subscribe for
         securities of the Company or any of its  subsidiaries  (excluding those
         referred to in Section 4.04(b)),  then in each such case the Conversion
         Rate shall be adjusted so that it shall  equal the rate  determined  by
         multiplying the Conversion Rate in effect immediately prior to the date
         of such distribution by a fraction, the numerator of which shall be the
         current  Market  Price per share  (determined  as  provided  in Section
         4.04(d)) of the Common Stock on the record date referred to below,  and
         the  denominator  of which shall be such current Market Price per share
         of the Common Stock less the then fair market value (as  determined  by
         the Board of  Directors of the Company,  whose  determination  shall be
         conclusive)  of the portion of the assets or evidences of  indebtedness
         or securities or assets so distributed or of such  subscription  rights
         or warrants  applicable to one share of Common Stock.  Such  adjustment
         shall become effective retroactively  immediately after the record date
         for  the  determination  of  stockholders   entitled  to  receive  such
         distribution.

                  (d) For the purpose of any computation  under Section 4.04(b),
         and 4.04(c), the current Market Price of a share of Common Stock on any
         date  shall  be  the  average  of  the  daily  Closing  Prices  for  10
         consecutive  Trading Days ending on the last Trading Day before the day
         in question.

                  (e) The  Company  shall be  entitled  to make such  additional
         adjustments in the Conversion  Price,  in addition to those required by
         subsections  4.04(a),  4.04(b),  and 4.04(c),  as shall be necessary in
         order that any dividend or distribution in shares of stock, subdivision
         or combination of shares of Common Stock,  issuance of rights,  options
         or  warrants,  evidences  of  indebtedness  or assets  (other than cash
         dividends  payable out of consolidated  earnings or retained  earnings)
         referred to above, shall not be taxable to the stockholders.

                  (f) In any case in which this Section 4.04 shall  require that
         an  adjustment  be made  retroactively  immediately  following a record
         date,  the Company  may elect to defer (but only for five (5)  Business
         Days  following  the  filing of the  statement  referred  to in Section
         4.04(h))  issuing to the holder of any Debentures  converted after such
         record date (i) the shares of Common Stock and other  capital  stock of
         the  Company  issuable  upon such  conversion  over and above  (ii) the
         shares of Common

                                       32
 <PAGE>
         Stock and other capital stock of the Company  issuable upon such  
         conversion on the basis of the conversion rate prior to adjustment.

                  (g) Notwithstanding any other provisions of this Section 4.04,
         the  Company  shall  not be  required  to make  any  adjustment  of the
         Conversion  Rate unless such  adjustment  would  require an increase or
         decrease of at least 1% in such Conversion Rate. Any lesser  adjustment
         shall be carried  forward and shall be made at the time of and together
         with the next subsequent adjustment which, together with any adjustment
         or  adjustments  so carried  forward,  shall  amount to an  increase or
         decrease of at least 1% in such rate.

                  (h) Whenever an adjustment in the Conversion Rate is required,
         the Company shall  forthwith place on file with the Trustee a statement
         signed by its Chief Executive Officer,  Chief Financial Officer,  Chief
         Operating  Officer or a Senior  Vice  President  and by its  Secretary,
         Assistant Secretary or Treasurer,  stating the adjusted Conversion Rate
         determined  as  provided  herein.  Such  statements  shall set forth in
         reasonable  detail such facts as shall be  necessary to show the reason
         and the  manner  of  computing  such  adjustment.  Promptly  after  the
         adjustment of the Conversion  Rate, the Company or Trustee shall mail a
         notice thereof to each holder of Debentures.

                  (i) The term "Common  Stock" as used in this  Indenture  means
         the Company's  Common Stock,  $.10 par value, as the same exists at the
         date of original issuance of the Debentures or any other class of stock
         resulting from successive changes or  reclassifications  of such Common
         Stock  consisting  solely of changes in par value, or from par value to
         no par value,  or from no par value to par value.  In the event that at
         any time as a result of an adjustment made pursuant to Section 4.04(a),
         the holder of any Debenture thereafter surrendered for conversion shall
         become  entitled to receive any shares of the Company other than shares
         of its  Common  Stock,  the  Conversion  Rate of such  other  shares so
         receivable upon conversion  shall be subject to adjustment from time to
         time in a manner and on terms as nearly  equivalent as  practicable  to
         the provisions with respect to Common Stock contained in  subparagraphs
         (a) through (g) of this Section  4.04,  and the  provisions  of Section
         4.01  through  4.03 and 4.05  through  4.11 with  respect to the Common
         Stock shall apply on like or similar terms to any such other shares.

                  (j) The  Conversion  Price shall be adjusted on March 30, 1998
         and on September 30, 1999 (each a "Reset Date") to the average  Closing
         Price of the Common  Stock for the ten (10)  trading  days  preceding a
         Reset Date plus 12% thereof if lower than the initial Conversion Price;
         provided, however, in

                                       33
<PAGE>
         no event shall the Conversion Price be reset at a  price lower than 15%
         below the initial  Conversion  Price as determined on the date of
         issuance or be reset on  September  30, 1999 at a price higher than
         the Conversion Price set on March 30, 1998.

                  SECTION  4.05.  Effect of  Reclassifications,  Consolidations,
Mergers or Sales on Conversion Privilege. In case of (a) any reclassification or
change of outstanding  shares of Common Stock issuable upon conversion of shares
of the Debentures  (other than a change in par value or from par value to no par
value or from no par  value to par  value,  or as a result of a  subdivision  or
combination), or (b) any consolidation or merger of the Company with one or more
other  corporations or entities  (other than a consolidation  or merger in which
the  Company  is the  continuing  company  and  which  does  not  result  in any
reclassification  or change of outstanding  shares of Common Stock issuable upon
conversion of the Debentures),  or (c) any sale or conveyance to another company
or other  entity of all or  substantially  all of the  property of the  Company,
then,  subject to the applicable  rights of the holders upon a Change in Control
(as  hereinbefore  defined),  the Company,  or such  successor  company or other
entity, as the case may be, shall make appropriate  provision so that the holder
of each  Debenture  then  outstanding  shall  have  the  right to  convert  such
Debenture  into the kind and amount of shares of stock or other  securities  and
property receivable upon such  consolidation,  merger,  sale,  reclassification,
change or  conveyance  by a holder of the number of shares of Common  Stock into
which  such  Debenture  might  have  been  converted  immediately  prior to such
consolidation, merger, sale, reclassification,  change or conveyance, subject to
adjustments  which shall be as nearly  equivalent as may be  practicable  to the
adjustments  provided for in this Section 4.05.  If in connection  with any such
reclassification,  consolidation, merger, sale, transfer, or share exchange each
holder  of  shares  of  Common  Stock is  entitled  to elect to  receive  either
securities,  cash or other  assets  upon  completion  of such  transaction,  the
Company  will  provide or cause to be provided to each holder of the  Debentures
the right to elect to receive the  securities,  cash or other  assets into which
the Debentures held by such holder will be convertible  after  completion of any
such transaction on the same terms and subject to the same conditions applicable
to holders of the Common Stock  (including,  without  limitation,  notice of the
right to elect,  limitations  on the period in which such  election will be made
and the effect of failing to exercise  the  election).  The  provisions  of this
Section 4.05 shall apply similarly to successive consolidations,  mergers, sales
reclassifications, transfers, exchanges or conveyances.

                SECTION  4.06.   Cancellation  of  Converted   Debentures.   All
Debentures or portions  thereof  surrendered for conversion  shall ipso facto on
the conversion  thereof be extinguished and shall be canceled and disposed of as
provided in Section 2.08, and no Debentures  shall be issued under the Indenture
in lieu thereof.

                SECTION  4.07.   Taxes  on   Conversion.   The  issue  of  stock
certificates  on conversions  of Debentures  shall be made without charge to the
converting

                                       34
<PAGE>
Debentureholder  for any issue tax in respect of such issue.  The Company  shall
not, however,  be required to pay any tax which may be payable in respect of any
transfer  involved in the issue and  delivery of stock in a name other than that
of the holder of the Debenture converted,  and the Company shall not be required
to issue or deliver  any such stock  certificate  unless and until the person or
persons  requesting  the  issuance  thereof  shall have paid to the  Company the
amount of any such tax or shall  have  established  to the  satisfaction  of the
Company that such tax has been paid.

                SECTION 4.08. Company to Reserve Stock. The Company shall at all
times  reserve  and keep  available,  free from  pre-emptive  rights  out of its
authorized  but unissued  stock,  for the purpose of effecting the conversion of
the Debentures,  such number of its duly  authorized  shares of Common Stock, as
shall  from  time  to  time  be  sufficient  to  effect  the  conversion  of all
outstanding Debentures.

                SECTION  4.09.  Covenant  as to  Common  Stock.  As a  condition
precedent to the taking of any action which would cause an  adjustment  reducing
the then prevailing Conversion Price below the then par value, if any, per share
of Common  Stock,  the Company  will take such  corporate  action as may, in the
opinion of its  counsel,  be necessary in order that the Company may validly and
legally  issue its  Common  Stock as fully paid and  nonassessable  stock at the
adjusted  conversion  price upon conversion of Debentures in accordance with the
provisions of this Article Four.

                If registration  with or approval of any governmental  authority
under any  federal  or state law is  required  before  any  Common  Stock may be
validly  issued upon  conversion,  the Company  covenants that it will take such
action as may be necessary to secure such registration or approval,  as the case
may be.

                SECTION 4.10.  Notice of Certain Corporate Action.  In case:

                         (a) the Company shall declare a dividend or any other
distribution on shares of its Common Stock payable otherwise than in cash out
of its consolidated earnings or retained earnings or in Common Stock; or

                         (b) the Company shall authorize the granting to all of
the holders of shares of its Common Stock of rights, options or warrants to
subscribe  for or purchase any shares of capital stock of any class (or
securities  convertible into or exchangeable for shares of capital stock of any
class) or of any other rights or warrants; or

                         (c) of any reclassification or change of shares of
Common Stock of the Company, or of any consolidation or merger of the Company 
with one or more other corporations, or of the sale or conveyance of all or
substantially all of the property of the Company;

                                       35
  <PAGE>
                       (d) of the voluntary or involuntary dissolution, 
liquidation or winding-up of the Company; or

                       (e) the Company or any subsidiary shall commence a tender
offer for all or a portion of any class of the Company's outstanding shares of
Common Stock that would require an adjustment of the Conversion Price pursuant
to Section 4.04;

then the Company shall cause notice thereof to be mailed to the Trustee,  to the
office or agency  maintained  by the Company for the  purpose of  conversion  of
Debentures  and to each holder of  Debentures,  at his address  appearing on the
registry  books  of the  Company,  at  least  20 days  (or l0  days in any  case
specified  in clause  (a) or (b)  above)  prior to the  applicable  record  date
hereinafter  specified, a notice stating (i) the date on which a record is to be
taken for the purpose of such dividend, distribution, rights or warrants, or, if
a record is not to be taken, the date as of which the holders of Common Stock of
record  to be  entitled  to such  dividend,  distribution,  rights,  options  or
warrants are to be determined,  or (ii) the date on which such reclassification,
consolidation,  merger, sale, conveyance, dissolution, liquidation winding-up or
tender  offer is  expected to become  effective,  and the date as of which it is
expected  that the holders of Common  Stock of record to be entitled to exchange
their shares of Common Stock for securities or other property  deliverable  upon
such reclassification,  consolidation,  merger, sale,  conveyance,  dissolution,
liquidation, winding-up or tender offer shall be determined. Failure to give any
such notice, or any defect therein, shall not affect the legality or validity of
any such action set forth in clause (a), (b), (c), (d) or (e) above.

                SECTION 4.11.  Disclaimer  of  Responsibility  of Trustee,  etc.
Neither  the  Trustee,  subject  to the  provisions  of  Section  8.0l,  nor any
conversion  agent shall at any time be under any duty or  responsibility  to any
holder of Debentures to determine  whether any facts exist which may require any
adjustment  of the  Conversion  Rate, or with respect to the nature or extent of
any such adjustment when made, or with respect to the method employed, or herein
or in any supplemental  indenture  provided to be employed,  in making the same.
Neither the Trustee nor any conversion  agent shall be accountable  with respect
to the validity or value (or the kind or amount) of any shares of Common  Stock,
or of any  securities  or property  (including  cash),  which may at any time be
issued or  delivered  upon the  conversion  of any  Debenture;  and  neither the
Trustee nor any conversion agent makes any representation  with respect thereto.
Neither the Trustee nor any paying agent shall be responsible for any failure of
the Company to make any cash payment or to issue, transfer or deliver any shares
of Common Stock or stock certificates or other securities or property (including
cash) upon the  surrender of any  Debenture  for the purpose of  conversion  or,
subject to Section  4.0l,  to comply  with any of the  covenants  of the Company
contained in this Article Four.

                                  ARTICLE FIVE

                       PARTICULAR COVENANTS OF THE COMPANY

                The Company covenants and agrees as follows:

                SECTION   5.01.   Payment  of   Principal  of  and  Interest  on
Debentures.  The Company  will duly and  punctually  pay or cause to be paid the
principal of and interest on each of the Debentures at the time and place and in
the manner provided in the Debenture.  The Company shall pay interest on overdue
principal and interest at the rate borne by the Debentures to the extent lawful.
An installment of principal or interest shall be considered  paid on the date it
is due if the payment  agent holds on or prior to that date money  deposited  by
the Company in immediately  available funds and designated for and sufficient to
pay such amount due and the  payment  agent is not  prohibited  from paying such
money  to the  Debentureholders  on  that  date  pursuant  to the  terms  of the
Indenture.

                SECTION 5.02. Maintenance of Offices or Agencies. As long as any
of the  Debentures  remain  outstanding,  the Company will maintain an office or
agency or offices or agencies in the Borough of Manhattan, City and State of New
York,  where the  Debentures  may be presented  for  registration,  transfer and
exchange  as in  this  Indenture  provided,  and  where  the  Debentures  may be
surrendered for conversion as in this Indenture provided,  and where notices and
demands to or upon the Company in respect of the Debentures or of this Indenture
may be served,  and where the  Debentures  may be presented  for payment.  Until
otherwise  designated by the Company in a notice to the Trustee,  such office or
agency for all of the above purposes shall be the Corporate  Trust Office of the
Trustee.  The Company will give to the Trustee  notice of any change of location
of any of such offices or agencies.  In case the Company  shall fail to maintain
such an office or agency or offices or agencies  for all such  purposes or shall
fail to give such notice of any change in the  location  thereof,  presentations
and demands may be made and notices may be served at the Corporate  Trust Office
of the Trustee.

                The  Company  may at any  time  and  from  time to time  vary or
terminate the appointment of any such agent or appoint any additional agents for
any or all of such purposes; provided, however, that until all of the Debentures
have been delivered to the Trustee for cancellation, or moneys sufficient to pay
the  principal of and interest on the  Debentures  have been made  available for
payment and either paid or returned  to the Company  pursuant to  provisions  of
Section 5.04, the Company will maintain in the Borough of Manhattan, the City of
New  York,  an  office  or  agency  where  Debentures  may  be  surrendered  for
registration  of transfer or exchange  and where  notices and demands to or upon
the Company in respect of the Debentures and this Indenture may be served.

                SECTION 5.03.  Appointment to Fill Vacancy in Office of Trustee.
The  Company,  whenever  necessary  to avoid or fill a vacancy  in the office of
Trustee,  will appoint,  in the manner  provided in Section 8.11, a Trustee,  so
that there shall at all times be a Trustee hereunder.

                SECTION  5.04.  Appointment  of Paying Agent Other Than Trustee.
(a) The Company initially  appoints the Trustee as Registrar and Paying Agent in
connection  with the  Debentures.  If the Company  shall  appoint a paying agent
other than the  Trustee,  it will cause such paying agent to execute and deliver
to the Trustee an  instrument  in which such agent shall agree with the Trustee,
subject to the provisions of this Section,

                         (1)  that it will hold all sums held by it as such
agent for the payment of the principal of or interest on the Debentures
(whether such sums have been paid to it by the Company or by any other obligor
on the  Debentures) in trust for the benefit of the holders of the Debentures, 
or of the Trustee, as the case may be, and

                         (2) that it will give the Trustee notice of any failure
by the Company (or by any other obligor on the Debentures)  to  make  any
payment  of  the  principal  of or  interest  on the Debentures when the same
shall be due and payable.

                (b) If the Company shall 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 the Debentures, set aside, segregate and hold in trust for the benefit of the
holders of the Debentures, a sum sufficient to pay such principal or interest so
becoming  due and will  notify the  Trustee of any  failure  (by it or any other
obligor on the Debentures) to take such action.

                (c) Anything in this  Section to the  contrary  notwithstanding,
the  agreement  to hold sums in trust as provided in this  Section is subject to
the provisions of Section 14.04 hereof.

                SECTION 5.05. Annual Report to Trustee. The Company will, within
120  days  after  the  end of each  fiscal  year  (which,  at the  date  hereof,
terminates  on September  30),  file with the Trustee an  Officers'  Certificate
stating  that a review of the  activities  of the Company  and its  Subsidiaries
during  the  preceding  fiscal  year  (or,  in the case of the  first  Officers'
Certificate  filed  during  the  period  from the date of  execution  hereof  to
September 30 of such year) has been made under the supervision of the signers of
such  certificate  with a view to  determining  whether  the  Company  has kept,
observed, performed and fulfilled all the covenants,  agreements and obligations
on its part in this Indenture  contained and that to the best of their knowledge
the Company is not in default in the  performance,  observance or fulfillment of
any of the terms,  provisions and conditions  hereof, and that no default exists
or, if the Company shall be so in default or if any default  exists,  specifying
all such  defaults,  and the nature and status  thereof,  of which they may have
knowledge.

                                       38
  <PAGE>
              SECTION  5.06.  Covenant  Regarding  Authorization.  The Company
represents and warrants that it is duly  authorized  under the laws of the State
of Delaware and under all other  provisions of law applicable  thereto to create
and issue the Debentures and to execute this Indenture, and all corporate action
on its part for the creation and issue of such  Debentures and the execution and
delivery  of this  Indenture  has been duly and  effectively  taken and that the
Debentures,  when issued,  will be valid and binding  obligations of the Company
and entitled to the benefits of this Indenture.

                  SECTION  5.07.  Delivery of Certain  Information.  At any time
when the  Company is not subject to Section 13 or 15(d) of the  Exchange  Act or
exempt from such requirements pursuant to Rule 12g3-2(b) under the Exchange Act,
upon the request of a holder of  Debentures or the holder of Common Stock issued
upon  conversion  thereof,  the  Company  will  promptly  furnish or cause to be
furnished Rule 144A  Information (as defined below) to such holder of Debentures
or such holder of Common Stock issued upon  conversion  of  Debentures,  or to a
prospective purchaser of any such security designated by any such holder, to the
extent  required  to permit  compliance  by such holder with Rule 144A under the
Securities  Act, as amended (or any successor  provision  thereto) in connection
with the resale of any such security;  provided, however, that the Company shall
not be required to furnish such  information in connection with any request made
on or after the date which is three  years from the later of (i) the date such a
security or any such predecessor security) was last acquired from the Company or
(ii) the  date  such a  security  (or any such  predecessor  security)  was last
acquired from an "affiliate" of the Company within the meaning of Rule 144 under
the Securities Act (or any successor provision thereto). "Rule 144A Information"
shall be such information as is specified  pursuant to Rule 144A(d)(4) under the
Securities Act (or any successor provision thereto).

                  SECTION 5.08.  Payment of Taxes and Other Claims.  The Company
will pay or discharge,  or cause to be paid or  discharged,  before the same may
become delinquent,  all stamps and other duties, if any, which may be imposed by
the United States or any political  subdivision thereof or therein in connection
with the issuance or conversion of any Debentures;  provided, however, that, (A)
the Company  shall not be required  to pay or  discharge  or cause to be paid or
discharged  any tax or duty whose  amount,  applicability  or  validity is being
contested in good faith by appropriate proceedings,  and (B) except as otherwise
provided  herein the Company  shall not be required to pay or discharge or cause
to be paid or  discharged  any  tax,  assessment  or other  governmental  charge
imposed  by any  government  or any  political  subdivision  thereof  or  taxing
authority thereof or therein.

                Section 5.09. Covenant as to Indebtedness.  The Company will not

Indebtedness of the Company or is expressly  subordinated in right of payment to
the Debentures and any other Senior Subordinated Indebtedness of the Company and

                                   ARTICLE SIX

                     DEBENTUREHOLDERS' LISTS AND REPORTS BY
                           THE COMPANY AND THE TRUSTEE

                SECTION  6.01.  Covenant  to Furnish  Information.  The  Company
covenants  and  agrees  that it will  furnish  or cause to be  furnished  to the
Trustee semi-annually,  not more than 15 days after each record date for payment
of  interest,  and at such other  times as the  Trustee  may request in writing,
within 30 days after receipt by the Company of any such request,  a list in such
form as the Trustee may reasonably  require  containing  all  information in the
possession  or control of the  Company  or any of its paying  agents,  as to the
names and addresses of the holders of the Debentures  obtained since the date as
of which the next previous list, if any, was furnished;  provided, however, that
as long as the Trustee  shall be the Debenture  Registrar  such list need not be
furnished.  Any such list may be dated as of a date not more than 15 days  prior
to the time such  information  is furnished or caused to be furnished,  and need
not include information received after such date.

                SECTION 6.02.  Preservation  of Information;  Communications  to
Debentureholders.  (a) The Trustee  shall  preserve,  in as current a form as is
reasonably  practicable,  all  information  as to the names and addresses of the
holders of Debentures  (1) contained in the most recent list  furnished to it as
provided in Section 6.01, (2) received by it in the capacity of paying agent (if
so acting) hereunder, (3) received by it in the capacity of Debenture Registrar,
and (4) filed with it within two preceding  years  pursuant to the provisions of
paragraph (2) of subsection (c) of Section 6.04.

                The Trustee may (1) destroy any list furnished to it as provided
in  Section  6.01 upon  receipt  of a new list so  furnished,  (2)  destroy  any
information  received  by it as  paying  agent  (if so  acting)  hereunder  upon
delivering  to itself as  Trustee,  not  earlier  than 45 days after an interest
payment date of the Debentures, a list containing the names and addresses of the
holders of Debentures  obtained from such information  since the delivery of the
next previous  list, if any, (3) destroy any list delivered to itself as Trustee
which was  compiled  from  information  received  by it as  paying  agent (if so
acting)  hereunder upon the receipt of a new list so delivered,  and (4) destroy
any  information  filed  with it by  holders of  Debentures  for the  purpose of
receiving  reports

                                       40
<PAGE>
pursuant to the provisions of paragraph (2) of subsection (c) of Section 6.04,
but not until two years after such  information  has been filed with it.

                (b) In case  three or more  holders of  Debentures  (hereinafter
referred to as "applicants") apply in writing to the Trustee, and furnish to the
Trustee  reasonable  proof that each such  applicant has owned a Debenture for a
period of at least six months preceding the date of such  application,  and such
application  states that the applicants desire to communicate with other holders
of  Debentures  with respect to their  rights under this  Indenture or under the
Debentures,  and is  accompanied  by a copy  of  the  form  of  proxy  or  other
communication which such applicants propose to transmit, then the Trustee shall,
within five business days after the receipt of such application at its election,
either

                         (1) afford to such applicants access to the information
preserved at the time by the Trustee in accordance with the provisions of
subsection (a) of this Section, or

                         (2) inform such applicants as to the approximate number
of holders of Debentures whose names and addresses  appear in the  information
preserved at the time by the Trustee, in accordance with the provisions of 
subsection (a) of this Section,  and as to the approximate cost of mailing to
such  Debentureholders the form of proxy or other communications, if any, 
specified in such application.

                If the Trustee shall elect not to afford such applicants  access
to such  information,  the  Trustee  shall,  upon the  written  request  of such
applicants,  mail to each Debentureholder  whose name and address appears in the
information  preserved  at the  time  by the  Trustee  in  accordance  with  the
provisions  of subsection  (a) of this  Section,  a copy of the form of proxy or
other  communication  which  is  specified  in  such  request,  with  reasonable
promptness  after a tender to the  Trustee of the  material  to be mailed and of
payment,  or provision for the payment,  of the reasonable  expenses of mailing,
unless  within  five days  after such  tender,  the  Trustee  shall mail to such
applicants and file with the Securities and Exchange Commission, together with a
copy of the material to be mailed,  a written  statement to the effect that,  in
the opinion of the Trustee, such mailing would be contrary to the best interests
of the holders of Debentures  or would be in violation of  applicable  law. Such
written  statement shall specify the basis of such opinion.  If said Commission,
after  opportunity  for a hearing upon the  objections  specified in the written
statement  so  filed,  shall  enter an order  refusing  to  sustain  any of such
objections  or if,  after the entry of an order  sustaining  one or more of such
objections,  said  Commission  shall  find,  after  notice and  opportunity  for
hearing,  that all the  objections so sustained have been met and shall enter an
order so  declaring,  the Trustee shall mail copies of such material to all such
Debentureholders  with reasonable  promptness  after the entry of such order and
the  renewal of such  tender;  otherwise  the  Trustee  shall be relieved of any
obligation or duty to such applicants respecting their application.

                (c) Each and every holder of the  Debentures,  by receiving  and
holding the same,  agrees with the  Company  and the  Trustee  that  neither the
Company nor the Trustee nor any paying agent shall be held accountable by reason
of the  disclosure of any such  information as to the names and addresses of the
holders of  Debentures in accordance  with the  provisions of subsection  (b) of
this Section,  regardless of the source from which such information was derived,
and that the  Trustee  shall not be held  accountable  by reason of mailing  any
material pursuant to a request made under said subsection (b).

                SECTION 6.03. Reports by Company.  (a) The Company covenants and
agrees to file with the Trustee  within 15 days after the Company is required to
file the same with the Securities and Exchange Commission,  copies of the annual
reports and of the  information,  documents and other reports (or copies of such
portions of any of the  foregoing  as said  Commission  may from time to time by
rules and regulations  prescribe) which the Company may be required to file with
said Commission  pursuant to Section 13 or Section 15(d) of the Exchange Act or,
if the  Company  is not  required  to file  information,  documents  or  reports
pursuant  to either of such  sections,  then to file with the  Trustee  and said
Commission,  in accordance  with rules and  regulations  prescribed from time to
time by said Commission,  such of the  supplementary  and periodic  information,
documents  and  reports  which may be  required  pursuant  to  Section 13 of the
Exchange  Act in  respect  of a security  listed  and  registered  on a national
securities  exchange  as may be  prescribed  from time to time in such rules and
regulations.

                (b) The  Company  covenants  and agrees to file with the Trustee
and the Securities  and Exchange  Commission,  in accordance  with the rules and
regulations  prescribed  from time to time by said  Commission,  such additional
information,  documents  and reports with respect to  compliance  by the Company
with the  conditions  and  covenants  provided  for in this  Indenture as may be
required from time to time by such rules and regulations.

                (c) The Company  covenants and agrees to transmit to the holders
of Debentures  within 30 days after the filing thereof with the Trustee,  in the
manner and to the extent provided in subsection (c) of Section 6.04 with respect
to reports  pursuant to subsection  (a) of said Section 6.04,  such summaries of
any  information,  documents  and  reports  required  to be filed by the Company
pursuant to subsections  (a) and (b) of this Section as may be required by rules
and  regulations  prescribed  from time to time by the  Securities  and Exchange
Commission.

April 15  following  execution of this  Indenture,  and on or before April 15 in
every year thereafter,  so long as any Debentures are outstanding hereunder, the
Trustee shall  transmit to the  Debentureholders  as hereinafter in this Section
provided a brief report dated as of the preceding February 15, with respect to:

        qualifications under Section 8.08, or in lieu thereof, if to the best of
        its knowledge it has  continued to be eligible and qualified  under such
        Sections, a written statement to such effect;

                           (2) the  character and amount of any advances (and if
        the Trustee elects so to state, the circumstances surrounding the making
        thereof)  made by the Trustee (as such) which remain  unpaid on the date
        of such  report,  and for the  reimbursement  of which it  claims or may
        claim a lien or charge, prior to that of the Debentures, on any property
        or  funds  held or  collected  by it as  Trustee,  if such  advances  so
        remaining  unpaid  aggregate  more than  one-half of one per cent of the
        principal  amount  of the  Debentures  outstanding  on the  date of such
        report;

                           (3) the amount,  interest  rate and maturity  date of
        all other  indebtedness owing by the Company (or by any other obligor on
        the Debentures) to the Trustee in its individual  capacity,  on the date
        of  such  report,  with a  brief  description  of any  property  held as
        collateral  security  therefor,  except  an  indebtedness  based  upon a
        creditor relationship arising in any manner described in paragraphs (2),
        (3), (4), or (6) of subsection (b) of Section 8.15;

                           (4)  the property and funds, if any, physically in
        the possession of the Trustee as such on the date of such report;

                           (5)  any additional issue of Debentures which the 
        Trustee has not previously reported; and 

                           (6)  any   action   taken  by  the   Trustee  in  the
        performance  of its  duties  under  this  Indenture  which  it  has  not
        previously  reported  and which in its  opinion  materially  affects the
        Debentures,  except action in respect of a default,  notice of which has
        been or is to be withheld by it in  accordance  with the  provisions  of
        Section 7.09.

                         (b) The Trustee shall transmit to the Debentureholders,
        as  hereinafter  provided,  a brief report with respect to the character
        and amount of any advances (and if the Trustee  elects so to state,  the
        circumstances  surrounding  the making  thereof)  made by the Trustee as
        such  since  the date of the last  report  transmitted  pursuant  to the
        provisions of  subsection  (a) of this Section (or if no such report has
        yet been so transmitted, since the date of execution of this Indenture),
        for the  reimbursement  of which it claims or may claim a lien or charge
        prior to that of the  Debentures  on property or funds held or collected
        by it as Trustee,  and which it has not previously  reported pursuant to
        this subsection, if such advances remaining unpaid at any time aggregate
        more 
                                       43

<PAGE>
        than ten per cent of the principal amount of Debentures outstanding
        at such time,  such report to be  transmitted  within 90 days after such
        time.

                         (c)      Reports pursuant to this Section shall be
        transmitted by mail:

                           (1)    to all registered holders of Debentures, as 
        the names and addresses of such holders appear upon the registration
        books of the Company;

                           (2) to such holders of Debentures as have, within two
        years preceding such transmission,  filed their names and addresses with
        the Trustee for that purpose; and

                           (3)  except  in the  cases  of  reports  pursuant  to
        subsection (b) of this Section, to each  Debentureholder  whose name and
        address  is  preserved  at the  time  by the  Trustee,  as  provided  in
        subsection (a) of Section 6.02.

                      (d) A copy of each such report shall,  at the time of such
        transmission  to  Debentureholders,  be filed by the  Trustee  with each
        securities  exchange upon which the  Debentures are listed and also with
        the Securities and Exchange Commission. The Company agrees to notify the
        Trustee  when and as the  Debentures  become  listed  on any  securities
        exchange.


                                  ARTICLE SEVEN

                  REMEDIES OF THE TRUSTEE AND DEBENTUREHOLDERS
                              ON EVENT OF DEFAULT.

                SECTION  7.01.  Events  of  Default  Defined;   Acceleration  of
Maturity.  In case one or more of the  following  Events of  Default  shall have
occurred and be continuing, that is to say:

                       (a)  default  in the  due  and  punctual  payment  of any
        installment  of interest upon any of the Debentures as and when the same
        shall become due and payable,  whether or not such payment is prohibited
        by the provisions of Article  Thirteen,  and continuance of such default
        for a period of 30 days; or

                       (b)  default  in the  due  and  punctual  payment  of the
        principal  of any  Debenture  as and when the same shall  become due and

                                       44

<PAGE>
        payable,  whether or not such payment is prohibited by the provisions of
        Article  Thirteen,  or fails  to  redeem  or  purchase  Debentures  when
        required  pursuant to this Indenture or the  Debentures,  whether or not
        prohibited  by the  provisions of Article  Thirteen  either at maturity,
        upon  redemption,  by  declaration as authorized by this  Indenture,  or
        otherwise; or

                       (c) failure on the part of the Company to duly observe or
        perform any of the covenants or agreements on the part of the Company in
        the Debentures or in this  Indenture,  for a period of 60 days after the
        date on which written  notice of such failure,  requiring the same to be
        remedied,  shall  have been  given to the  Company  by the  Trustee,  by
        registered  mail, or to the Company and the Trustee by the holders of at
        least  twenty-five  per  cent  in  aggregate  principal  amount  of  the
        Debentures at the time outstanding; or

                       (d) a decree or order by a court having  jurisdiction  in
        the premises  shall have been entered  adjudging the Company as bankrupt
        or  insolvent,  or approving a petition  seeking  reorganization  of the
        Company  under  the  Bankruptcy  Code or any  other  similar  applicable
        Federal  or State law,  and such  decree or order  shall have  continued
        undischarged  or unstayed for a period of 60 days;  or a decree or order
        of a court having  jurisdiction in the premises for the appointment of a
        receiver  or   liquidator  or  trustee  or  assignee  in  bankruptcy  or
        insolvency  of  the  Company  or of  all  or  substantially  all  of its
        property, or for the winding up or liquidation of its affairs shall have
        been  entered,  and such  decree or order  shall have  remained in force
        undischarged or unstayed for a period of 60 days; or

                       (e)  the  Company  shall  institute   proceedings  to  be
        adjudicated  a voluntary  bankrupt,  or shall consent to the filing of a
        bankruptcy  proceeding against it, or shall file a petition or answer or
        consent  seeking  reorganization  under the Bankruptcy Code or any other
        similar  applicable Federal or State law, or shall consent to the filing
        of any such petition,  or shall consent to the appointment of a receiver
        or  liquidator  or trustee or assignee in bankruptcy or insolvency of it
        or of all  or  substantially  all of its  property,  or  shall  make  an
        assignment  for the benefit of creditors,  or shall admit in writing its
        inability  to pay its debts  generally as they become due; or failure to
        purchase  Debentures  on the  Repurchase  Date  following  a  Change  in
        Control.

then and in each and every such case (other  than an Event of Default  specified
in clause (d) and (e) of this  Section  7.01),  so long as such Event of Default
shall not have been remedied,  unless the principal of all the Debentures  shall
have already  become due and  payable,  either the Trustee or the holders of not
less than  twenty-five per cent in aggregate  principal amount of the Debentures
then  outstanding  hereunder,  by notice in writing to the  Company  (and to the
Trustee if given by the Debentureholders),  may

                                       45
<PAGE>
declare the  principal  of all the  Debentures  then  outstanding  to be due and
payable  immediately,  and upon any such  declaration  the same shall become and
shall be immediately due and payable,  anything in this Indenture or in the said
Debentures  contained  to the contrary  notwithstanding.  If an Event of Default
specified in clause (d) or (e) of this Section 7.01 occurs, the principal of and
interest on all the Debentures  shall ipso facto become and be  immediately  due
and payable  without any  declaration or other act on the part of the Trustee or
the holders of any of the Debentures. This provision, however, is subject to the
condition that if, at any time after the principal of the Debentures  shall have
been so declared due and payable,  but before the  Debentures  shall have become
due by their  terms and before  any  judgment  or decree for the  payment of the
moneys due shall have been  obtained  or entered as  hereinafter  provided,  the
Company shall pay or shall deposit with the Trustee a sum  sufficient to pay all
matured  installments of interest upon all the Debentures  then  outstanding and
the principal of any and all Debentures then outstanding which shall have become
due otherwise  than by  acceleration  (with interest upon such principal and, to
the extent the payment of such interest is  enforceable  under  applicable  law,
upon overdue  installments  of interest,  at the rate per annum expressed in the
Debentures to the date of such payment or deposit) and the amount payable to the
Trustee under Section 8.06. If any and all defaults under the  Indenture,  other
than the  nonpayment  of principal or interest on  Debentures  then  outstanding
which has become due because of  acceleration  or a default in conversion of any
Debentures;  shall have been remedied or provision shall have been made therefor
to the satisfaction of the Trustee, - then and in every such case the holders of
a majority in aggregate principal amount of the Debentures then outstanding,  by
written  notice to the Company and to the  Trustee,  may waive all  defaults and
rescind and annul such declaration and its  consequences;  but no such waiver or
rescission and annulment shall conflict with any judgment or decree or extend to
or shall affect any  subsequent  default,  or shall impair any right  consequent
thereon.

                SECTION  7.02.  Rescission  and  Annulment.  In case the Trustee
shall  have  proceeded  to  enforce  any right  under  this  Indenture  and such
proceedings shall have been discontinued or abandoned because of such rescission
or annulment or for any other reason or shall have been determined  adversely to
the  Trustee,  then  and in every  case the  Company  and the  Trustee  shall be
restored  respectively to their former positions and rights  hereunder,  and all
rights,  remedies  and powers of the Company and the Trustee  shall  continue as
though no such proceedings had been taken.

                SECTION  7.03.   Collection  of   Indebtedness   and  Suits  for
Enforcement by Trustee.  The Company covenants that (1) in case default shall be
made in the payment of any installments of interest on any of the Debentures, as
and when the same shall  become due and  payable,  and such  default  shall have
continued  for a period of 30 days,  or (2) in case default shall be made in the
payment  of the  principal  of any of the  Debentures  when the same  shall have
become  due  and  payable,  whether  upon  maturity  of the  Debentures  or upon
redemption  or  repurchase or  declaration  as  authorized by

                                       46
<PAGE>
this Indenture or otherwise-then,  upon demand by the Trustee,  the Company will
pay to the  Trustee,  for the  benefit  of the  holders of the  Debentures  then
outstanding, the whole amount that then shall have become due and payable on all
such  Debentures  for  principal or interest,  as the case may be, with interest
upon the overdue  principal  and (to the extent that payment of such interest is
enforceable  under applicable law) upon overdue  installments of interest at the
rate per annum  expressed  in the  Debentures;  and, in addition  thereto,  such
further  amount  as shall be  sufficient  to cover the  costs  and  expenses  of
collection, and the amount payable to the Trustee under Section 8.06.

                In case the Company  shall fail  forthwith  to pay such  amounts
upon such  demand,  the  Trustee,  in its own name and as  trustee of an express
trust, shall be entitled and empowered to institute any action or proceedings at
law or in  equity  for the  collection  of the sums so due and  unpaid,  and may
prosecute any such action or  proceedings  to judgment or final decree,  and may
enforce any such  judgment or final decree  against the Company or other obligor
upon the  Debentures  and  collect  in the  manner  provided  and to the  extent
permitted  by law out of the  property of the Company or other  obligor upon the
Debentures wherever situated the moneys adjudged or decreed to be payable.

                SECTION  7.04.  Trustee May File  Proofs of Claims.  The Trustee
shall be  entitled  and  empowered,  either in its own name or as  trustee of an
express trust, or as attorney-in-fact  for the holders of the Debentures,  or in
any one or more of such  capacities,  to file such proof of debt,  amendment  of
proof  of debt,  claim,  petition  or  other  document  as may be  necessary  or
advisable  in order to have the claims of the  Trustee and of the holders of the
Debentures  allowed  in  any  equity   receivership,   insolvency,   bankruptcy,
liquidation, readjustment, reorganization or other judicial proceedings relative
to the Company or any other  obligor on the  Debentures or their  creditors,  or
affecting their property.  The Trustee is hereby irrevocably  appointed (and the
successive  respective  holders of the Debentures by taking and holding the same
shall be  conclusively  deemed to have so  appointed  the  Trustee) the true and
lawful  attorney-in-fact  of the  respective  holders  of the  Debentures,  with
authority  to make  and  file in the  respective  names  of the  holders  of the
Debentures or on behalf of the holders of the Debentures as a class,  subject to
deduction  from any such claims of the amounts of any claims filed by any of the
holders of the Debentures  themselves,  any proof of debt, amendment of proof of
debt,  claim,  petition or other document in any such proceedings and to receipt
payment of any sums becoming  distributable on account  thereof,  and to execute
any such other papers and  documents and to do and perform any and all such acts
and  things  for and on  behalf  of such  holders  of the  Debentures  as may be
necessary  or  advisable  in the  opinion  of the  Trustee  in order to have the
respective  claims of the Trustee and of the holders of the  Debentures  against
the  Company  or its  property  allowed in any such  proceeding,  and to receive
payment  of or on  account  of such  claims;  provided,  however,  that  nothing
contained in this Indenture  shall be deemed to give to the Trustee any right to
accept or consent to any plan of  reorganization  or  otherwise by action of any
character in any such  proceeding to waive or change in any way any right of any
Debentureholder.

                                       47

                All  rights  of  action  and  of  asserting  claims  under  this
Indenture or under any of the Debentures may be enforced by the Trustee  without
the possession of any of the  Debentures or the production  thereof at any trial
or other proceeding relative thereto, and any such suit or proceeding instituted
by the  Trustee  shall be  brought  in its own name and as trustee of an express
trust,  and any  recovery  of judgment  shall,  after  provision  for payment of
expenses and of the reasonable  compensation,  disbursements and advances of the
Trustee,  its agents and counsel,  be for the ratable  benefit of the holders of
the Debentures, subject to the provisions of this Indenture.

                SECTION  7.05.  Application  of  Moneys  Collected  by  Trustee.
Subject to the provisions of Article  Thirteen  hereof,  any moneys collected by
the Trustee,  pursuant to Section 7.03, shall be applied in the order following,
at the date or dates fixed by the Trustee,  and, in case of the  distribution of
such  moneys on account of  principal  or  interest,  upon  presentation  of the
several Debentures and stamping thereon the payment, if only partially paid, and
upon surrender thereof if fully paid:

                       FIRST:  To the payment of costs and expenses of
         collection, and of all amounts payable to the Trustee under Section 
         8.06;

                       SECOND:   In  case  the  principal  of  the   outstanding
        Debentures  shall not have  become due and be unpaid,  to the payment of
        interest  on  the  Debentures,  in the  order  of  the  maturity  of the
        installments  of such  interest,  with interest (so far as may be lawful
        and if such interest has been collected by the Trustee) upon the overdue
        installments  of  interest  at  the  rate  per  annum  expressed  in the
        Debentures,  such  payments to be made  ratably to the persons  entitled
        thereto, without discrimination or preference;

                       THIRD:   In  case  the   principal  of  the   outstanding
        Debentures  shall have become due, by  declaration as authorized by this
        Indenture  or  otherwise,  to the payment of the whole amount then owing
        and unpaid upon the Debentures for principal and interest, with interest
        on the  overdue  principal  and  (so  far as may be  lawful  and if such
        interest has been collected by the Trustee) upon overdue installments of
        interest at the rate per annum expressed in the Debentures;  and in case
        such moneys shall be insufficient to pay in full the whole amount so due
        and unpaid upon the  Debentures,  then to the payment of such  principal
        and interest,  without preference or priority of principal over interest
        or of interest over principal or of any installment of interest over any
        other  installment  of  interest,  or of any  Debenture  over any  other
        Debenture,  ratably to the  aggregate of such  principal and accrued and
        unpaid interest; and

                       FOURTH:  To the payment of the remainder, if any, to the
        Company, its successors or assigns, or to whomsoever may be lawfully
       
                                       48

        entitled to receive the same, or as a court of competent jurisdiction
        may direct.

                SECTION  7.06.  Limitation  on Suits by Holders  of  Debentures.
Except  as  otherwise  expressly  provided  in this  Article,  no  holder of any
Debenture  shall have any right by virtue or by availing itself of any provision
in this  Indenture or otherwise to institute  any suit,  action or proceeding in
equity  or at law upon or  under  or with  respect  to this  Indenture,  for the
appointment  of a receiver or trustee,  for the  execution of any trust or power
hereof, or for any other remedy hereunder, unless:

                         (1) such holder previously shall have given to the
Trustee written notice of default and of the continuance thereof, as
hereinbefore provided;

                         (2) the holders of not less than 25% in aggregate
principal amount of the Debentures then outstanding, shall have made  written
request  upon the Trustee  either to proceed to exercise the powers hereinbefore
granted or to institute such action, suit, or proceeding in its own name as
Trustee  hereunder,  and such holders  shall have offered to the Trustee such 
reasonable indemnity as it may require against the costs,  expenses and
liabilities to be incurred therein or thereby;

                         (3) the Trustee  within a reasonable  time (which in no
event shall be less than 60 days) after its receipt of such  notice,  request 
and offer of  indemnity,  shall have failed to proceed to exercise such powers
or to institute any such action, suit or proceeding;

                         (4) no direction inconsistent with such written request
have been given to the Trustee during such 60-day period by the holder of a
majority in principal  amount of the  Debentures  then outstanding, it being
understood and intended,  and being expressly covenanted by the taker and holder
of every  Debenture  with every other taker and holder and the Trustee,  that no
one or more holders of Debentures shall have any right in any manner whatever by
virtue or by availing of any provision of this  Indenture to affect,  disturb or
prejudice  the  rights of the  holders  of any other of such  Debentures,  or to
obtain or seek to obtain  priority  over or preference to any other such holder,
or to enforce  any right  under  this  Indenture,  except in the  manner  herein
provided  and for the  equal,  ratable  and  common  benefit  of all  holders of
Debentures.  For  the  protection  and  enforcement  of the  provisions  of this
Section,  each and every  Debentureholder  and the Trustee  shall be entitled to
such relief as can be given either at law or in equity.

                Nothing herein  contained shall,  however,  affect or impair the
right,  which is absolute and unconditional,  of any  Debentureholder to receive
and to institute  suit to enforce,  the payment of the principal of and interest
or premium,  if any, on his  Debentures  at and after the  respective  due dates
(including  maturity,  by call for redemption or by declaration pursuant to this
Indenture  which has not been  rescinded  pursuant to the  provisions of Section
7.01, or otherwise) of such  principal or interest,

                                       49
<PAGE>

or premium,  if any, or the obligation of the Company, which is also absolute 
and unconditional,  to pay the principal of and interest or premium,  if any,
on each of the  Debentures to the respective holders thereof at the times and
places in the Debentures expressed.

                SECTION 7.07. Delay or Omission in Exercise of Rights Not Waiver
of  Default.  No delay or omission of the Trustee or of any holder of any of the
Debentures  to exercise  any right or power  accruing  upon any Event of Default
shall impair any such right or power or shall be construed to be a waiver of any
such default or an  acquiescence  therein;  and,  subject to the  provisions  of
Section  7.04,  every power and remedy given by this Article  Seven or by law to
the Trustee or to the  Debentureholders  may be exercised from time to time, and
as  often  as  shall  be   deemed   expedient,   by  the   Trustee   or  by  the
Debentureholders.

                SECTION 7.08.  Right of Holders of Majority in Principal  Amount
of Debentures to Direct Trustee and Waive Defaults. Subject to the provisions of
Sections 8.0l and 8.02, the holders of a majority in aggregate  principal amount
of the Debentures at the time outstanding, determined in accordance with Section
9.04,  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,  however, that such direction shall
not be  otherwise  than  in  accordance  with  law and  the  provisions  of this
Indenture,  and the Trustee shall have the right,  subject to the  provisions of
Section  8.01,  to decline to follow any such  direction  if the Trustee  shall,
being  advised by  counsel,  determine  that the action so  directed  may not be
lawfully taken, or if the Trustee in good faith shall, by a Responsible  Officer
or officers of the Trustee,  determine  that the proceeding so directed would be
illegal or involve it in personal liability or that the action so directed would
be unduly  prejudicial  to the  holders of  Debentures  not taking  part in such
direction;  and provided,  further,  that nothing in this Indenture shall impair
the right of the  Trustee to take any action  deemed  proper by the  Trustee and
which is not inconsistent with such direction by the Debentureholders.  Prior to
the  declaration  of the maturity of the Debentures as provided in Section 7.01,
the holders of a majority in aggregate principal amount of the Debentures at the
time  outstanding,  determined in accordance with Section 9.04, may on behalf of
the holders of all of the  Debentures  waive any past default  hereunder and its
consequences, except a default in the payment of the principal of or interest on
any of the  Debentures or in the  conversion of  Debentures.  In the case of any
such waiver, the Company, the Trustee and the holders of the Debentures shall be
restored to their former positions and rights  hereunder,  respectively;  but no
such waiver shall extend to any  subsequent or other default or impair any right
consequent thereon.

                SECTION  7.09.  Trustee to Give Notice of Defaults  Known to It,
but May Withhold in Certain Circumstances. The Trustee shall, within ninety days
after the occurrence of a default, give to the  Debentureholders,  in the manner
and to the extent  provided in  subsection  (c) of Section  6.04 with respect to
reports pursuant to subsection (a) of said Section 6.04,  notice of all defaults
known to the  Trustee,  unless

                                       50
<PAGE>

such  defaults  shall have been cured before the giving of such notice (the term
"defaults"  for the  purposes of this  Section  being  hereby  defined to be the
events  specified in clauses (a), (b),  (c), (d) and (e), of Section  7.0l,  not
including  (i) any  periods of grace  provided  for therein and (ii) the written
notice specified in clause (c) of Section 7.0l);  provided,  that, except in the
case of default in the  payment of the  principal  of or  interest on any of the
Debentures,  the Trustee shall be protected in withholding such notice if and so
long as the board of directors, the executive committee, or a trust committee of
directors and/or Responsible  Officers,  of the Trustee in good faith determines
that the withholding of such notice is in the interests of the Debentureholders.

                SECTION 7.10. Requirement of Undertaking to Pay Costs in Certain
Suits Under Indenture or Against  Trustee.  All parties to this Indenture agree,
and each holder of any  Debenture by his  acceptance  thereof shall be deemed to
have agreed,  that any court may in its discretion  require, 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,  the
filing by any party  litigant in such suit of an undertaking to pay the costs of
such suit, and that such court may in its discretion  assess  reasonable  costs,
including  reasonable  attorney's fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party  litigant;  provided,  that the  provisions of this Section shall not
apply to any suit  instituted  by the  Trustee,  to any suit  instituted  by any
Debentureholder,  or group of  Debentureholders,  holding in the aggregate  more
than 10% in  principal  amount  of the  Debentures  outstanding,  or to any suit
instituted  by any  Debentureholder  for the  enforcement  of the payment of the
principal of or interest on any Debenture, on or after the due date expressed in
such Debenture.

                SECTION  7.11.   Unconditional   Right  of  Holders  to  Receive
Principal and Interest and to Convert.  Notwithstanding  any other  provision in
this  Indenture,  the holder of any  Debentures  shall have the right,  which is
absolute and unconditional,  to receive payment of the principal of and interest
on such Debentures on the stated maturities expressed in such Debentures (or, in
the case of redemption or repurchase, on the Redemption Date or Repurchase Date,
as the case may be), and to convert such  Debentures in accordance  with Article
Four, and to institute suit for the enforcement of any such payment and right to
convert,  and such  rights  shall not be  impaired  without  the consent of such
holder.

                SECTION 7.12. Restoration of Rights and Remedies. If the Trustee
or any holder of a Debenture has  instituted any proceeding to enforce any right
or remedy under this  Indenture and such  proceeding  has been  discontinued  or
abandoned for any reason, or has been determined  adversely to the Trustee or to
such holder,  then and in every such case,  subject to any determination in such
proceeding,  the  Company,  the Trustee and the holders of  Debentures  shall be
restored  severally and  respectively  to their former  positions  hereunder and
thereafter  all  rights and  remedies  of the  Trustee  and such  holders  shall
continue as though no such proceeding had been instituted.

                                       51

<PAGE>
                SECTION  7.13.  Rights  and  Remedies   Cumulative.   Except  as
otherwise  provided  with respect to the  replacement  or payment of  mutilated,
destroyed,  lost or stolen  Debentures in the last paragraph of Section 2.07, no
right or remedy  herein  conferred  upon or  reserved  to the  Trustee or to the
holders of  Debentures is intended to be exclusive of any other right or remedy,
and every right and remedy shall, to the extent  permitted by law, be cumulative
and 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  7.14.  Waiver of Usury,  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  or 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.


                                  ARTICLE EIGHT

                             CONCERNING THE TRUSTEE

                SECTION  8.01.  Duty of  Trustee  Prior  to and  After  Event of
Default.  The Trustee,  prior to the occurrence of an Event of Default and after
the  curing or  waiving  of all  Events  of  Default  which  may have  occurred,
undertakes to perform such duties and only such duties as are  specifically  set
forth in this Indenture. In case an Event of Default has occurred (which has not
been cured or waived) the Trustee  shall  exercise such of the rights and powers
vested  in it by this  Indenture,  and use the same  degree of care and skill in
their exercise,  as a prudent man would exercise or use under the  circumstances
in the conduct of his own affairs.

                The  Trustee  upon  receipt  of all  resolutions,  certificates,
statements,  opinions, reports, documents, orders or other instruments furnished
to the Trustee  pursuant to any provision of this Indenture,  shall examine them
to determine whether they conform to the requirements of this Indenture.

                No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent  action,  its own negligent failure
to act, or its own willful misconduct, except that:

                                       52
<PAGE>  
                     (a) prior to the  occurrence  of an Event of Default  and
        after the curing or waiving of all such Events of Default which may have
        occurred:

                           (1) the duties and  obligations  of the Trustee shall
        be determined  solely by the express  provisions of this Indenture,  and
        the  Trustee  shall not be liable  except  for the  performance  of such
        duties and obligations as are  specifically set forth in this Indenture,
        and no  implied  covenants  or  obligations  shall  be  read  into  this
        Indenture against the Trustee; and

                           (2) in the  absence  of bad  faith on the part of the
        Trustee,  the  Trustee  may  conclusively  rely,  as to the truth of the
        statements and the correctness of the opinions expressed  therein,  upon
        any certificates or opinions  furnished to the Trustee and conforming to
        the requirements of this Indenture;

                       (b) the Trustee  shall not be  personally  liable for any
        error  of  judgment  made in good  faith  by a  Responsible  Officer  or
        Responsible Officers of the Trustee,  unless it shall be proven that the
        Trustee was negligent in ascertaining the pertinent facts; and

                       (c) the  Trustee  shall  not be  personally  liable  with
        respect to any action  taken,  suffered  or omitted to be taken by it in
        good faith in  accordance  with the direction of the holders of not less
        than a  majority  in  principal  amount  of the  Debentures  at the time
        outstanding  (determined  as provided in Section  9.04)  relating to the
        time,  method  and place of  conducting  any  proceeding  for any remedy
        available to the Trustee,  or  exercising  any trust or power  conferred
        upon the Trustee, under this Indenture.

                SECTION 8.02.  Certain Rights of Trustee:

                            (a) the Trustee may rely and shall be protected in
acting or refraining from acting upon any resolution, Officers' Certificate,
certificate of a firm of independent public accountants, or any other 
certificate,  statement,  instrument,  opinion,  report,  notice, request,
consent, order, appraisal,  bond, debenture or other paper or document believed
by it to be genuine and to have been signed or  presented by the proper party 
or parties;

                            (b) any request, direction, order or demand by the
Company mentioned herein shall be sufficiently evidenced by an instrument  
signed in the name of the Company by the Chairman of the Board,  the President 
or a Vice  President and the Secretary or an Assistant Secretary or the 
Treasurer or an Assistant  Treasurer  (unless other evidence in respect thereof
be herein  specifically  prescribed);  and any resolution 

                                       53

<PAGE>
of the Board of Directors  may be evidenced to the Trustee by a copy thereof  
certified by the Secretary or an Assistant Secretary of the Company;

                            (c) the Trustee may consult with counsel and any 
Opinion of Counsel shall be full and complete authorization and protection in 
respect of any action taken, suffered or omitted by it hereunder in good faith 
and in accordance with such Opinion of Counsel;

                            (d) the Trustee shall be under no obligation to
exercise  any of the  trusts or powers  vested  in it by this  Indenture  at the
request,  order or  direction  of any of the  Debentureholders,  pursuant to the
provisions of this Indenture, unless such Debentureholders shall have offered to
the Trustee  reasonable  security or indemnity  against the costs,  expenses and
liabilities  which may be incurred therein or thereby;  nothing herein contained
shall, however, relieve the Trustee of the obligation, upon the occurrence of an
Event of Default  (which has not been cured or waived) to  exercise  such of the
rights and powers vested in it by this Indenture,  and to use the same degree of
care and skill in their  exercise as a prudent  man would  exercise or use under
the circumstances in the conduct of his own affairs;

                            (e) the Trustee shall not be personally liable for
any action taken,  suffered or omitted by it in good faith and believed by it to
be authorized or within the discretion or rights or powers  conferred upon it by
this Indenture;
                            (f) prior to the occurrence of an Event of Default
hereunder and after the curing or waiving of all Events of Default,  the Trustee
shall not be bound to make any investigation into the facts or matters stated in
any resolution,  certificate,  statement,  instrument,  opinion, report, notice,
request,  consent, order, approval,  bond, debenture, or other paper or document
unless  requested in writing so to do by the holders of not less than a majority
in principal amount of the Debentures then outstanding;  provided, however, that
if the payment within a reasonable time to the Trustee of the costs, expenses or
liabilities  likely to be incurred by it in the making of such investigation is,
in the  opinion of the  Trustee,  not  reasonably  assured to the Trustee by the
security afforded to it by the terms of this Indenture,  the Trustee may require
reasonable  indemnity  against  such  expense or  liability as a condition to so
proceeding.  The reasonable  expense of every such examination  shall be paid by
the Company  or, if paid by the  Trustee,  shall be repaid by the  Company  upon
demand;

                            (g) the Trustee may execute any of the trusts or
powers  hereunder  or perform  any duties  hereunder  either  directly  or by or
through agents or attorneys; and
 
                           (h) none of the provisions of this Indenture shall 
require the Trustee to expend or risk its own funds or otherwise  incur any 
personal  financial  liability in the performance of any of its duties  
hereunder,  or in the exercise of any of its rights or powers, if it shall have
reasonable  grounds for  believing  that  repayment of 

                                       54
<PAGE>

such  funds  or  adequate  indemnity  against  such  risk  or  liability  is not
reasonably assured to it.

                SECTION  8.03.  Trustee  Not Liable for  Recitals or Issuance of
Debentures.  The recitals contained herein and in the Debentures (other than the
certificate  of  authentication  on  the  Debentures)  shall  be  taken  as  the
statements of the Company,  and the Trustee  assumes no  responsibility  for the
correctness of the same. The Trustee makes no representations as to the validity
or sufficiency of this Indenture or of the Debentures.  The Trustee shall not be
accountable  for the use or  application by the Company of any of the Debentures
or of the  proceeds of such  Debentures,  or for the use or  application  of any
moneys  paid  over by the  Trustee  in  accordance  with any  provision  of this
Indenture,  or for the use or application  of any moneys  received by any paying
agent.

                SECTION 8.04. Trustee or Others May Hold Debentures. The Trustee
or any paying agent or any Debenture  Registrar,  in its individual or any other
capacity,  may become the owner or pledgee of Debentures with the same rights it
would have if it were not Trustee or any paying agent or Debenture Registrar.

                The Trustee may become and act as Trustee under other indentures
under which other  securities,  or certificates of interest or  participation in
other  securities,  of the Company are  outstanding  in the same manner as if it
were not Trustee or any paying agent or Debenture Registrar.

                SECTION 8.05.  Moneys Held in Trust.  All moneys received by the
Trustee shall,  until used or applied as herein  provided,  be held in trust for
the purposes for which they were received, but need not be segregated from other
funds  except to the  extent  required  by law.  The  Trustee  shall be under no
liability  for interest on any moneys  received by it  hereunder.  So long as no
Event of Default shall have occurred and be continuing,  all interest allowed on
any such moneys  shall be paid from time to time upon the  written  order of the
Company,  signed by its Chairman of the Board,  President or a Vice President or
its Treasurer or an Assistant Treasurer.

                SECTION 8.06.  Compensation, Reimbursement and Indemnity.
The Company covenants and agrees

                (1) to pay to the  Trustee  from time to time,  and the  Trustee
shall be entitled to, reasonable compensation (which shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust)
for all services  rendered by it in the execution of the trusts  hereby  created
and in the exercise and performance of any of the powers and duties hereunder of
the Trustee;

                (2) the  Company  will pay or  reimburse  the  Trustee  upon its
request for all reasonable expenses, disbursements and advances incurred or made
by the  Trustee  in  accordance  with any of the  provisions  of this  Indenture
(including the reasonable

                                       55
<PAGE>

compensation  and the  expenses  and  disbursements  of its  counsel  and of all
persons not regularly in its employ)  except any such expense,  disbursement  or
advance as may arise from its negligence or bad faith;

                (3) the Company  will  indemnify  the Trustee  for,  and hold it
harmless against,  any loss, liability or expense incurred without negligence or
bad faith on the part of the Trustee and  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 of liability in the premises.

                The  obligations of the Company under this Section to compensate
the Trustee and to pay or reimburse the Trustee for expenses,  disbursements and
advances shall constitute  additional  indebtedness  hereunder.  Such additional
indebtedness shall be secured by a lien prior to that of the Debentures upon all
property and funds held or  collected by the Trustee as such,  except funds held
in trust for the benefit of the holders of particular Debentures.

                The provisions of this Section shall survive the  termination of
this Indenture or the earlier resignation or removal of the Trustee.

                SECTION   8.07.   Right  of   Trustee   to  Rely  on   Officers'
Certificates.  Except as  otherwise  provided in Section  8.01,  whenever in the
administration  of the  trusts  of this  Indenture  the  Trustee  shall  deem it
necessary or desirable that a matter be proved or  established  prior to taking,
suffering or omitting any action  hereunder,  such matter (unless other evidence
in  respect  thereof  be  herein  specifically  prescribed)  may be deemed to be
conclusively  proved  and  established  by an  Officers'  Certificate,  and such
certificate shall be full warrant to the Trustee for any action taken,  suffered
or omitted by it under the provisions of this Indenture upon the faith thereof.

                SECTION  8.08.  Conflicting  Interests.  When this  Indenture is
governed by the Trust  Indenture  Act,  if the  Trustee  has or shall  acquire a
conflicting interest within the meaning of Section 310(b) of the Trust Indenture
Act, the Trustee shall either  eliminate such interest or resign,  to the extent
and in the manner  provided  by, and  subject  to the  provisions  of, the Trust
Indenture  Act and this  Indenture.  In  determining  whether  the  Trustee  has
conflicting  interests as defined in Section  310(b)(1)  of the Trust  Indenture
Act, the provisions  contained in the proviso to said Section 310(b)(1) shall be
deemed incorporated herein.

                SECTION  8.09.  Notice  of  Default.  Within  90 days  after the
occurrence of any default hereunder as to which the Trustee has received written
notice,  the  Trustee  shall give to all  holders of  Debentures,  in the manner
provided in Section 6.04(c),  notice of such default,  unless such default shall
have been  cured or waived;  provided,  however,  that,  except in the case of a
default in the payment of the principal of, or interest on any  Debentures,  the
Trustee  shall be  protected  in  withholding  such notice if and so long as the
board of directors,  the executive committee,  or a trust

                                       56

<PAGE>
committee  of  directors  or  Responsible  Officers of the Trustee in good faith
determine that the withholding of such notice is in the interest of the holders.
For the purpose of this Section, the term "default" means any event which is, or
after  notice or lapse of time or both would  become,  an Event of Default.  The
proviso  to the first  sentence  of this  Section  8.09  shall be in lieu of the
proviso to Section  315(b) of the Trust  Indenture  Act, which latter proviso is
hereby expressly excluded from this Indenture.

                SECTION  8.10.  Requirements  for  Eligibility  of Trustee.  The
Trustee  hereunder  shall at all  times be a  corporation  organized  and  doing
business under the laws of the United States or any State or Territory or of the
District of Columbia  authorized  under such laws to  exercise  corporate  trust
powers, having a combined capital and surplus of at least $1,000,000, subject to
supervision  or  examination  by  Federal,  State,  Territorial,  or District of
Columbia authority.  If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of the aforesaid supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such  corporation  shall be deemed to be its combined capital and
surplus as set forth in its most recent  report of  condition so  published.  In
case at any time the Trustee shall cease to be eligible in  accordance  with the
provisions of this Section,  the Trustee shall resign  immediately in the manner
and with the effect specified in Section 8.11.

                SECTION 8.11. Resignation and Removal of Trustee; Appointment of
Successor.  (a) The Trustee,  or any successor hereafter  appointed,  may at any
time resign and be discharged  from the trust hereby  created by mailing  notice
thereof to the Company  and to the  Debentureholders  whose names and  addresses
appear in the  information  preserved  at the time by the Trustee in  accordance
with  the  provisions  of  Section  6.02(a).   Upon  receiving  such  notice  of
resignation,  the Company shall promptly appoint a successor  trustee by written
instrument, in duplicate,  executed by order of the Board of Directors, one copy
of which instrument shall be delivered to the resigning  Trustee and one copy to
the successor trustee.  If no successor trustee shall have been so appointed and
have  accepted  appointment  within 30 days after the  mailing of such notice of
resignation   the  resigning   Trustee  may  petition  any  court  of  competent
jurisdiction for the appointment of a successor trustee,  or any Debentureholder
who has been a bona fide holder of a Debenture  or  Debentures  for at least six
months may,  subject to the provisions of Section 7.10, on behalf of himself and
all others similarly situated,  petition any such court for the appointment of a
successor trustee. Such court may thereupon after such notice, if any, as it may
deem proper and prescribe, appoint a successor trustee.

                       (b) In case at any time any of the following shall occur:

                       (1) the Trustee shall fail to comply with the  provisions
        of Section 8.08 after written request  therefor by the Company or by any
        Debentureholder  who has  been a bona  fide  holder  of a  Debenture  or
        Debentures for at least six months;


                                       57
<PAGE>

                       (2) the Trustee  shall cease to be eligible in accordance
        with the  provisions  of  Section  8.10 and shall  fail to resign  after
        written request therefor by the Company or by any such  Debentureholder;
        or

                       (3) the Trustee  shall  become  incapable  of acting,  or
        shall be adjudged as bankrupt or insolvent, or a receiver of the Trustee
        or of its property shall be appointed,  or any public officer shall take
        charge or control of he Trustee or of its  property  or affairs  for the
        purpose of rehabilitation, conservation or liquidation,

then,  in any such  case,  the  Company  may remove the  Trustee  and  appoint a
successor trustee by written instrument, in duplicate,  executed by order of the
Board of  Directors,  one copy of which  instrument  shall be  delivered  to the
Trustee so removed and one copy to the  successor  trustee,  or,  subject to the
provisions of Section 7.10, any  Debentureholder who has been a bona fide holder
of a Debenture or  Debentures  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.  Such
court may  thereupon  after  such  notice,  if any,  as it may deem  proper  and
prescribe, remove the Trustee and appoint a successor trustee.

                (c) The holders of a majority in aggregate  principal  amount of
the  Debentures at the time  outstanding  may at any time remove the Trustee and
appoint a successor trustee.

                (d)  Any   resignation   or  removal  of  the  Trustee  and  any
appointment  of a successor  trustee  pursuant to any of the  provisions of this
Section shall become  effective upon  acceptance of appointment by the successor
trustee as provided in Section 8.12.

                SECTION 8.12.  Acceptance by Successor to Trustee. Any successor
trustee  appointed as provided in Section 8.11 shall  execute,  acknowledge  and
deliver to the Company and to its  predecessor  trustee an instrument  accepting
such  appointment  hereunder,  and thereupon the  resignation  or removal of the
predecessor  trustee shall become effective and such successor trustee,  without
any further  act,  deed or  conveyance,  shall  become fully vested with all the
rights, powers, duties and obligations of its predecessor  hereunder,  with like
effect as if originally named as trustee herein. The predecessor  trustee,  upon
payment to it of all amounts due it under Section 8.06 shall,  nevertheless,  at
the written request of the successor trustee,  pay over to the successor trustee
all moneys at the time held by it hereunder; and the Company and the predecessor
trustee shall execute and deliver such  instruments  and do such other things as
may  reasonably be required for more fully and certainly  vesting and confirming
in the successor trustee all such rights, powers, duties and obligations.

                                       58
  
<PAGE>

              No successor  trustee  shall accept  appointment  as provided in
this Section unless at the time of such acceptance such successor  trustee shall
be  qualified  under the  provisions  of  Section  8.08 and  eligible  under the
provisions of Section 8.10.

                Upon  acceptance  of  appointment  by  a  successor  trustee  as
provided in this  Section,  the Company  shall mail notice of the  succession of
such trustee hereunder to all Debentureholders at their last addresses appearing
upon the registry books.

                SECTION 8.13. Successor to Trustee by Merger or Consolidation or
Succession to Business.  Any corporation into which the Trustee may be merged or
with which it may be consolidated,  or any corporation resulting from any merger
or  consolidation  to which the  Trustee  shall be a party,  or any  corporation
succeeding to the business of the Trustee, shall be the successor of the Trustee
hereunder,  provided such corporation shall be qualified under the provisions of
Section 8.08 and eligible  under the  provisions  of Section  8.10,  without the
execution  or filing of any paper or any  further  act on the part of any of the
parties hereto, anything herein to the contrary notwithstanding.

         SECTION 8.14.  Authenticating Agents. The Trustee may, with the consent
of the Company, appoint an additional  authenticating agent or agents acceptable
to the Company with respect to the  Debentures  which shall be authorized to act
on behalf of the Trustee to  authenticate  Debentures  issued  upon  exchange or
substitution  pursuant to this Indenture.  (Each such agent  hereinafter  called
"Authenticating Agent").

         Debentures  authenticated by an Authenticating  Agent 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,  and every reference in
this Indenture to the  authentication  and delivery of Debentures by the Trustee
or the  Trustee's  certificate  of  authentication  shall be deemed  to  include
authentication and delivery on behalf of the Trustee by an Authenticating  Agent
and a  certificate  of  authentication  executed  on behalf of the Trustee by an
Authenticating  Agent. Each Authenticating  Agent shall be subject to acceptance
by 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 and subject to  supervision  or  examination by government or other fiscal
authority.  If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section 8.14, such  Authenticating  Agent
shall  resign  immediately  in the manner and with the effect  specified in this
Section 8.14.

         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  8.14,  without 

                                       59
<PAGE>

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   8.14,   the  Trustee  may  appoint  a  successor
Authenticating  Agent which shall be subject to acceptance  by the Company.  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 as if originally named as an Authenticating  Agent.
No successor  Authenticating  Agent shall be appointed unless eligible under the
provisions of this Section 8.14.

         The  Company  agrees to pay to each  Authenticating  Agent from time to
time reasonable compensation for its services under this Section 8.14.

         If an Authenticating  Agent is appointed with respect to the Debentures
pursuant to this Section 8.14,  the  Debentures  may have endorsed  thereon,  in
addition to or in lieu of the  Trustee's  certification  of  authentication,  an
alternative certificate of authentication in the following form:

         "This is one of the Debentures referred to in the within-mentioned
Indenture.

Dated:                     [                      ]
                           as Trustee
                           By [Authenticating agent].
                             as Authenticating Agent

                        By______________________________
                             Authorized Signatory "


                [In case any Debentures 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  Debentures  so  authenticated  with  the  same  effect  as if such
successor trustee had itself authenticated such Debentures.]

                SECTION 8.15. Preferential Collection of Claims Against Company.
(a) Subject to the provisions of subsection (b) of this Section,  if the Trustee
in its  individual  capacity  shall be or shall  become a creditor,  directly or
indirectly,  secured or unsecured, of the Company or of any other obligor on the
Debentures within three

                                       60

<PAGE>

months prior to a default,  as defined in  subsection  (c) of this  Section,  or
subsequent  to such a default,  then,  unless and until  such  default  shall be
cured, the Trustee shall set apart and hold in a special account for the benefit
of the Trustee  individually,  the holders of the  Debentures and the holders of
other indenture securities (as defined in subsection (c) of this Section):

                       (1) an  amount  equal  to any and all  reductions  in the
        amount  due and owing  upon any claim as such  creditor  in  respect  of
        principal  or  interest,  effected  after the  beginning  of such  three
        months' period and valid as against the Company and its other creditors,
        except any such  reduction  resulting from the receipt or disposition of
        any property described in paragraph (2) of this subsection,  or from the
        exercise of any right of set-off which the Trustee could have  exercised
        if a petition  in  bankruptcy  had been filed by or against  the Company
        upon the date of such default; and

                       (2) all  property  received  by the Trustee in respect of
        any  claim  as  such  creditor,  either  as  security  therefor,  or  in
        satisfaction or composition  thereof, or otherwise,  after the beginning
        of such three months' period,  or an amount equal to the proceeds of any
        such property, if disposed of, subject,  however, to the rights, if any,
        of the  Company  and  its  other  creditors  in  such  property  or such
        proceeds.

                Nothing herein contained, however, shall affect the right of the
                Trustee:

                                (A) to retain for its own account  (i)  payments
                made on account of any such claim by any person  (other than the
                Company)  who is liable  thereon,  and (ii) the  proceeds of the
                bona  fide  sale of any  such  claim by the  Trustee  to a third
                person,  and (iii)  distributions made in cash,  securities,  or
                other property in respect of claims filed against the Company in
                bankruptcy or receivership or in proceedings for  reorganization
                pursuant to the Bankruptcy Code or applicable State law;

                                (B) to realize,  for its own  account,  upon any
                property  held by it as  security  for any such  claim,  if such
                property  was so held  prior  to the  beginning  of  such  three
                months' period;

                                (C) to realize, for its own account, but only to
                the extent of the claim hereinafter mentioned, upon any property
                held by it as  security  for any such  claim,  if such claim was
                created after the  beginning of such a three months'  period and
                such property was received as security  therefor  simultaneously
                with the creation thereof,  and if the Trustee 

                                       61
<PAGE>

               shall  sustain  the  burden of  proving  that at the time such
               property  was so received  the  Trustee had no  reasonable
               cause to believe  that a default,  as defined in subsection (c)
               of this Section, would occur within three months; or

                                (D) to receive  payment on any claim referred to
                in  paragraph  (B) or (C),  against the release of any  property
                held as security  for such claim as  provided in such  paragraph
                (B) or (C),  as the case may be, to the extent of the fair value
                of such property.

                For the  purposes of  paragraphs  (B),  (C),  and (D),  property
substituted after the beginning of such a three months' period for property held
as security at the time of such  substitution  shall,  to the extent of the fair
value of the property  released,  have the same status as the property released,
and,  to the extent  that any claim  referred  to in any of such  paragraphs  is
created in renewal of or in  substitution  for or for the purpose of repaying or
refunding any  pre-existing  claim of the Trustee as such  creditor,  such claim
shall have the same status as such pre-existing claim.

                If the  Trustee  shall be  required  to  account,  the funds and
property  held  in such  special  account  and the  proceeds  thereof  shall  be
apportioned between the Trustee,  the  Debentureholders and the holders of other
indenture  securities in such manner that the Trustee,  the Debentureholders and
the holders of other indenture  securities realize, as a result of payments from
such special  account and  payments of  dividends  on claims  filed  against the
Company in bankruptcy  or  receivership  or in  proceedings  for  reorganization
pursuant to the Bankruptcy Code or applicable  State law, the same percentage of
their  respective  claims,  figured before crediting to the claim of the Trustee
anything  on  account  of the  receipt  by it from the  Company of the funds and
property in such special account and before  crediting to the respective  claims
of the  Trustee,  the  Debentureholders  and  the  holders  of  other  indenture
securities  dividends  on claims  filed  against  the Company in  bankruptcy  or
receivership  or in proceedings  for  reorganization  pursuant to the Bankruptcy
Code or applicable State law, but after crediting thereon receipts on account of
the indebtedness  represented by their respective  claims from all sources other
than from such dividends and from the funds and property so held in such special
account.  As used  in this  paragraph,  with  respect  to any  claim,  the  term
"dividends"  shall  include any  distribution  with  respect to such  claim,  in
bankruptcy or receivership or in proceedings for reorganization  pursuant to the
Bankruptcy Code or applicable  State law,  whether such  distribution is made in
cash, securities, or other property, but shall not include any such distribution
with respect to the secured  portion,  if any, of such claim. The court in which
such bankruptcy,  receivership or proceeding for reorganization is pending shall
have jurisdiction (i) to apportion between the Trustee, the Debentureholders and
the holders of other indenture securities,  in accordance with the provisions of
this  paragraph,  the funds and property  held in such  special  account and the
proceeds thereof, or (ii) in lieu of such apportionment, in whole or in part, to
give to the provisions of this paragraph

                                       62

<PAGE>

due consideration in determining the fairness of the distributions to be made to
the Trustee,  the Debentureholders and the holders of other indenture securities
with  respect  to  their  respective  claims,  in which  event  it shall  not be
necessary  to  liquidate  or to appraise  the value of any  securities  or other
property held in such special  account or as security for any such claim,  or to
make a specific  allocation  of such  distributions  as between  the secured and
unsecured  portions of such claims, or otherwise to apply the provisions of this
paragraph as a mathematical formula.

                Any Trustee who has resigned or been removed after the beginning
of such a three  months  period  shall  be  subject  to the  provisions  of this
subsection (a) as though such  resignation  or removal had not occurred.  If any
Trustee has  resigned or been  removed  prior to the  beginning  of such a three
months period,  it shall be subject to the provisions of this  subsection (a) if
and only if the following conditions exist:

                         (i) the receipt of property or reduction of claim which
                would have  given rise to the  obligation  to  account,  if such
                Trustee had continued as trustee,  occurred  after the beginning
                of such three months period; and

                         (ii) such  receipt of  property or  reduction  of claim
                occurred within three months after such resignation or removal.

                (b) There shall be excluded from the operation of subsection
 (a) of this Section a creditor relationship arising from

                         (1) the ownership or acquisition  of securities  issued
                under any  indenture,  or any  security or  securities  having a
                maturity of one year or more at the time of  acquisition  by the
                Trustee;

                         (2) advances  authorized by  receivership or bankruptcy
                court of competent jurisdiction,  or by this Indenture,  for the
                purpose of  preserving  any property  which shall at any time be
                subject  to the lien of this  Indenture  or of  discharging  tax
                liens or other prior liens or encumbrances thereon, if notice of
                such  advance and of the  circumstances  surrounding  the making

                         CONCERNING THE DEBENTUREHOLDERS

                SECTION  9.01.  Evidence  of Action  Taken by  Debentureholders.
Whenever  in this  Indenture  it is  provided  that the  holders of a  specified
percentage in aggregate  principal  amount of the Debentures may take any action
(including  the  making of any  demand or  request,  the  giving of any  notice,
consent or waiver or the taking of any other action),  the fact that at the time
of taking any such action the holders of such specified  percentage  have joined
therein may be evidenced (a) by any  instrument or any number of  instruments of
similar  tenor  executed by  Debentureholders  in person or by attorney or proxy
appointed in writing,  or (b) by the record of the holders of Debentures  voting
in favor  thereof at any  meeting of  Debentureholders  duly  called and held in
accordance  with the  provisions of Article Ten, or (c) by a combination of such
instrument   or   instruments   and  any  such  record  of  such  a  meeting  of
Debentureholders.

                SECTION 9.02.  Proof of Execution of Instruments  and of Holding
of Debentures. Subject to the provisions of Section 8.01, proof of the execution
of any instrument by a Debentureholder or his attorney or proxy and proof of the
holding  by any  person of any of the  Debentures  shall be  sufficient  for any
purpose of this Indenture if made in the following manner:

                         (a) The  fact  and  date of the  execution  by any such
                person of any instrument may be proven by the certificate of any
                notary public or other officer of any  jurisdiction of or within
                the United States of America  authorized to take  acknowledgment
                of deeds, that the person executing such instrument acknowledged
                to him the execution thereof, or by an affidavit of a witness to
                such  execution  sworn to before  any such  notary or other such
                officer,  or by  any  other  method  deemed  appropriate  by the
                Trustee; and

                         (b) The ownership of Debentures  shall be proven by the
                registers of such  Debentures  or by a  certificate  of any duly
                appointed registrar thereof.

                                       65

<PAGE>
  
              The  Trustee  shall not be bound to  recognize  any  person as a
Debentureholder  unless  and until his  title to the  Debentures  held by him is
proved in the manner in this Article provided.

                The record of any  Debentureholders'  meeting shall be proven in
the manner provided in Section 10.06.

                The  Trustee  may require  such  additional  proof of any matter
referred to in this Section as it shall deem necessary.

                SECTION 9.03. Registered Holders of Debentures May be Treated as
Owners. Prior to due presentment for registration of transfer,  the Company, the
Trustee,  any paying agent and any  Debenture  Registrar  may deem and treat the
person in whose name any  Debenture  shall be  registered  upon the books of the
Company as the absolute owner of such  Debenture  (whether or not such Debenture
shall be overdue and  notwithstanding any notice of ownership or writing thereon
made by anyone),  for the purpose of  receiving  payment of or on account of the
principal  of and interest on such  Debenture  and for all other  purposes,  and
neither  the Company  nor the  Trustee  nor any paying  agent nor any  Debenture
Registrar shall be affected by any notice to the contrary.  All such payments so
made to any such registered  holder, for the time being or upon his order, shall
be valid,  and, to the extent of the sum or sums so paid,  effectual  to satisfy
and discharge the liability for moneys payable upon any such Debenture.

                SECTION   9.04.   Debentures   Owned  by   Company   Deemed  Not
Outstanding.  In  determining  whether  the holders of the  requisite  aggregate
principal  amount of  Debentures  have  concurred in any  direction,  consent or
waiver under this  Indenture,  Debentures  which are owned by the Company or any
other  obligor  on  the  Debentures  or by any  person  directly  or  indirectly
controlling or controlled by or under direct or indirect common control with the
Company or any other obligor on the Debentures  shall be disregarded  and deemed
not to be outstanding for the purpose of any such determination, except that for
the purpose of determining  whether the Trustee shall be protected in relying on
any such direction,  consent or waiver only  Debentures  which the Trustee knows
are so owned  shall be so  disregarded.  Debentures  so owned  which  have  been
pledged in good faith may be regarded as  outstanding  for the  purposes of this
Section,  if the pledgee shall establish to the  satisfaction of the Trustee the
pledgee's  right to vote such  Debentures  and that the  pledgee is not a person
directly or indirectly  controlling or controlled by or under direct or indirect
common control with the Company or any such other obligor.  In case of a dispute
as to such right,  any decision by the Trustee  taken upon the advice of counsel
shall be full protection to the Trustee.

                SECTION 9.05.  Action by  Debentureholders  Binds Future Holder.
Any  demand,  request,  waiver,  consent or vote of the holder of any  Debenture
shall be conclusive and binding upon such holder and upon all future holders and
owners of

                                       66

<PAGE>

such  Debenture,  and of any Debenture  issued in exchange  therefor or in place
thereof,  irrespective  of whether or not any notation in regard thereto is made
upon  such  Debenture.  Any  action  taken by the  holders  of the  majority  or
percentage in aggregate  principal  amount of the  Debentures  specified in this
Indenture in connection with such action shall be conclusively  binding upon the
Company, the Trustee and the holders of all the Debentures.

                to  take   any   other   action   authorized   to  be  taken  by
                Debentureholders  pursuant to any of the  provisions  of Article
                Seven;

                Section 11.02; or

                amount  of the  Debentures  under any  other  provision  of this

<PAGE>

                Any meeting of Debentureholders shall be valid without notice if
the holders of all Debentures then outstanding are present in person or by proxy
or if notice  is  waived  before or after  the  meeting  by the  holders  of all

duly authorized  representatives  or have,  before or after the meeting,  waived
notice.

                SECTION 10.03.  Call of Meetings by Company or Certain  Holders.

of  Debentureholders  to take any action  specified in Section 10.01, by written
request  setting forth in reasonable  detail the action  proposed to be taken at
the meeting and the time and place in the Borough of  Manhattan,  City and State

request is received at least 35 days before such meeting.

                SECTION  10.04.  Persons  Entitled  to Vote At a Meeting.  To be
entitled  to vote at any  meeting of  Debentureholders  a person  shall (a) be a

Debentures,  be dissolved. In any other case, the meeting may be adjourned for a
period of not less than 10 days as  determined  by the  chairman  of the meeting

proven in the manner  specified in said Section 9.02 or by having the  signature

temporary chairman of the meeting,  unless the meeting shall have been called by
the Company or by  Debentureholders  as provided in Section 10.03, in which case
the Company or the  Debentureholders  calling the  meeting,  as the case may be,
shall in like manner appoint a temporary  chairman.  A permanent  chairman and a

meeting shall have no right to vote other than by virtue of  Debentures  held by
him or instruments in writing as aforesaid duly designating him as the person to
vote on behalf of other  Debentureholders.  Any meeting of Debentureholders duly
called  pursuant to the

of Debentures or of their  representatives  by proxy. The permanent  chairman of
the meeting  shall appoint two  inspectors  of votes,  who shall count all votes
cast at the meeting for or against  any  resolution  and who shall make and file
with the secretary of the meeting their verified written reports in duplicate of
all votes cast at the meeting.  A record in duplicate of the proceedings of each
meeting of  Debentureholders  shall be prepared by the  secretary of the meeting
and  there  shall  be  attached  to said  record  the  original  reports  of the
inspectors of votes on any vote by ballot taken thereat and affidavits by one or
more persons having  knowledge of the facts,  setting forth a copy of the notice
of the meeting  and  showing  that said notice was mailed as provided in Section
10.02.  The  record  shall be  signed  and  verified  by the  affidavits  of the
permanent  chairman and secretary of the meeting and one of the duplicates shall
be  delivered to the Company and the other to the Trustee to be preserved by the
Trustee, the latter to have attached thereto the ballots voted at the meeting.

                Any record so signed and verified  shall be conclusive  evidence
of the matters therein stated.

                SECTION 10.08. No Delay. Nothing in this Article contained shall
be  deemed or  construed  to  authorize  or  permit,  by reason of any call of a
meeting of  Debentureholders  or any rights  expressly  or  impliedly  conferred

or rights  conferred upon or reserved to the Trustee or to the  Debentureholders
under any of the provisions of this Indenture or of the Debentures.

this Indenture and to make any further  appropriate  agreements and stipulations
which may be therein contained,  but the Trustee shall not be obligated to enter
into any such  supplemental  indenture  which  affects the Trustee's own rights,
duties or immunities under this Indenture or otherwise.

                Any supplemental  indenture authorized by the provisions of this
Section may be  executed  by the Company and the Trustee  without the consent of
the holders of any of the  Debentures at the time  outstanding,  notwithstanding
any of the provisions of Section 11.02.

                SECTION   11.02.   Supplemental   Indentures   with  Consent  of
Debentureholders.  With the consent  (evidenced  as provided in Section 9.01) of
the holders (or persons  entitled to vote,  or to give consents  respecting  the
same)  of  not  less  than a  majority  in  aggregate  principal  amount  of the
Debentures at the time outstanding, the Company, when authorized by a resolution
of its Board of Directors, and the Trustee may from time to time and at any time
enter into an indenture or indentures  supplemental  hereto (which shall conform
to the provisions of the Trust  Indenture Act of 1939 as then in effect) for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the  provisions  of this  Indenture  or of any  supplemental  indenture or of
modifying  in any  manner  the  rights  and  obligations  of the

                                       71

<PAGE>

holders of the Debentures  including any amendments  hereto which may affect the
rights of  Debentureholders  to  enforce  their  rights to  receive  payment  of
principal of and interest on the  Debentures  or to convert such  Debentures  in
accordance with the terms hereof and of the Company; provided,  however, that no
such  supplemental  indenture  shall  (i)  extend  the  fixed  maturity  of  any
Debentures, or reduce the principal amount thereof, or reduce the rate or extend
the  time  of  payment  of  interest  thereon,   or  change  the  conversion  or
subordination provisions in a manner adverse to the holders, without the consent
of the holder of each Debenture so affected,  or (ii) reduce the requirements of
Section  10.05  for  quorum or voting or  reduce  the  aforesaid  percentage  of
Debentures the holders of which are required to consent to any such supplemental
indenture,   without  the  consent  of  the  holders  of  all  Debentures   then
outstanding; or (iii) modify the obligation of the Company to maintain an office
or agency in the  Borough of  Manhattan  City and State of New York  pursuant to
Section 5.02.

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

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

                Promptly  after the  execution by the Company and the Trustee of
any  supplemental  indenture  pursuant to the  provisions of this  Section,  the
Company  shall mail a notice,  setting  forth in general  terms the substance of
such supplemental  indenture,  to all  Debentureholders  at their last addresses
appearing  upon the  registry  books.  Any  failure of the  Company to mail such
notice, or any defect therein,  shall not, however,  in any way impair or affect
the validity of any such supplemental indenture.

                SECTION  11.03.  Effect  of  Supplemental  Indentures.  Upon the
execution  of any  supplemental  indenture  pursuant to the  provisions  of this
Article,  this  Indenture  shall be and be deemed to be modified  and amended in
accordance   therewith  and  the  respective  rights,   limitations  of  rights,
obligations,  duties and  immunities  under this  Indenture of the Trustee,  the
Company and the holders of Debentures shall thereafter be determined,  exercised
and  enforced  hereunder  subject  in all  respects  to such  modifications  and
amendments,  and all the terms and conditions of any such supplemental indenture
shall be deemed to be part of the terms and conditions of this Indenture for any
and all purposes.

              SECTION 11.04. Notation on Debentures in Respect of Supplemental
Indentures.  Debentures  authenticated  and delivered after the execution of any
supplemental  indenture pursuant to the provisions of this Article, or after any
action taken at a Debentureholders'  meeting pursuant to Article Ten, may bear a
notation in form  approved by the Trustee as to any matter  provided for in such
supplemental  indenture or as to any action taken at any such  meeting;  and, in
such case,  suitable  notation  may be made upon  outstanding  Debentures  after
proper  presentation  and  demand.  If the  Company  or  the  Trustee  shall  so
determine,  new  Debentures  so modified  as to  conform,  in the opinion of the
Trustee  and the  Board of  Directors,  to any  modification  of this  Indenture
contained in any such supplemental indenture, or to any action taken at any such
meeting,  may be  prepared  by the  Company,  authenticated  by the  Trustee and
delivered in exchange for the Debentures then  outstanding,  upon demand by, and
without cost to, the holders thereof, upon surrender of such Debentures.

                SECTION  11.05.  Trustee  May Receive  Opinion of  Counsel.  The
Trustee,  subject to the  provisions of Section 8.01,  may receive an Opinion of
Counsel as conclusive evidence that any supplemental indenture executed pursuant
to this Article is  authorized  or permitted by the terms of this  Indenture and
that it is not inconsistent therewith.  The Trustee shall not be obliged to join
in the  execution  of any  supplemental  indenture  unless it shall  receive  an
Officers'  Certificate  stating  that no  consent  to the  execution  thereof is
required of any holder of Senior  Indebtedness  at the time  outstanding or that
such consents have been obtained.


                                 ARTICLE TWELVE

                         CONSOLIDATION, MERGER AND SALE

                SECTION 12.01.  Company May Consolidate,  etc. Nothing contained
in this Indenture or in any of the Debentures shall prevent any consolidation or
merger  of the  Company  with or into  any  other  corporation  or  corporations
(whether or not affiliated with the Company),  or successive  consolidations  or
mergers in which the Company or its successor or successors  shall be a party or
parties,  or  shall  prevent  any sale or  conveyance  (or  successive  sales or
conveyances)  of the property and assets of the Company (or of its  successor or
successors)  as an  entirety  or  substantially  as an  entirety,  to any  other
corporation  (whether or not affiliated with the Company)  authorized to acquire
the same;  provided,  however,  (a)(i) the Company is the surviving  corporation
following such merger or (ii) the corporation (if other than the Company) formed
by such  consolidation  or into which the Company is merged or the person  which
acquires by conveyance or transfer the  properties  and assets of the Company is
organized  under  the laws of the  United  States or any  state  thereof  or the
District of Columbia and assumes upon any such  consolidation,  merger,  sale or
conveyance, the due and punctual payment of the principal of and interest on all
of  the  Debentures,  according  to  their  tenor,  and  the  due  and  punctual
performance  and 

                                      73

<PAGE>

observance of all the terms,  covenants and  conditions of this  Indenture to be
kept or performed by the Company, by indenture supplemental hereto, satisfactory
in form to the Trustee, executed and delivered to the Trustee by the corporation
formed by such consolidation,  or into which the Company shall have been merged,
or by the  corporation  which shall have acquired such property and assets;  and
(b) immediately after giving effect to such transaction, no Event of Default and
no event which, after notice or lapse of time, or both, would become an Event of
Default, shall have happened and be continuing. In the event of any such sale or
conveyance the predecessor Company may be dissolved,  wound up and liquidated at
any time thereafter.

                SECTION 12.02. Successor Corporation to be Substituted.  In case
of any such consolidation,  merger, sale or conveyance and upon the execution by
the successor  corporation of an indenture  supplemental  hereto, as provided in
Section 12.01,  such successor  corporation  shall succeed to and be substituted
for the  Company,  with the same  effect as if it had been  named  herein as the
party of the first part.  Such successor  corporation  thereupon may cause to be
signed, and may issue either in its own name or in the name of the Company, with
such  suitable  reference,  if  any,  to  such  consolidation,  merger,  sale or
conveyance  as may be  required  by the  Trustee,  any or all of the  Debentures
issuable  hereunder which  theretofore shall not have been signed by the Company
and  delivered to the Trustee;  and,  upon the written  order of such  successor
corporation,  instead of the Company,  and subject to all the terms,  conditions
and limitations in this Indenture prescribed, the Trustee shall authenticate and
shall  deliver  any  Debentures  which  previously  shall  have been  signed and
delivered by the officers of the Company to the Trustee for authentication,  and
any Debentures  which such successor  corporation  thereafter  shall cause to be
signed in accordance  with the provisions of this Indenture and delivered to the
Trustee for that  purpose.  All the  Debentures  so issued shall in all respects
have the same legal rank and  benefit  under this  Indenture  as the  Debentures
theretofore or thereafter  issued in accordance with the terms of this Indenture
as though all of such  Debentures  had been issued at the date of the  execution
hereof.

                In case of any such  consolidation,  merger, sale or conveyance,
such changes in  phraseology  and form (but not in substance) may be made in the
Debentures thereafter to be issued as may be appropriate.

                Nothing  contained in this Indenture or in any of the Debentures
shall prevent the Company from consolidating or merging into itself or acquiring
by  purchase  or  otherwise  all  or  any  part  of the  property  of any  other
corporation (whether or not affiliated with the Company).

                SECTION  12.03.  Opinion of Counsel as  Evidence.  The  Trustee,
subject to the  provisions of Section 8.01, may receive an Opinion of Counsel as
conclusive evidence that any such consolidation, merger, sale or conveyance, and
any such assumption, complies with the provisions of this Article.

                                ARTICLE THIRTEEN

                           SUBORDINATION OF DEBENTURES

                SECTION 13.01.  Agreement to Subordinate;  Senior Subordination.
The Company  covenants and agrees and the Trustee and each holder of Debentures,
by his acceptance thereof,  likewise covenants and agrees, that the indebtedness
evidenced  by the  Debentures  and all  Obligations  of the  Company  under this
Indenture and the payment of any Claims is hereby expressly subordinated, to the
extent and in the manner hereinafter set forth, in right of payment to the prior
payment in full of all Senior Indebtedness. The Debentures shall in all respects
rank pari passu with all other Senior  Subordinated  Indebtedness of the Company
and only  indebtedness  of the Company which is Senior  Indebtedness  shall rank
senior to the  Debentures in accordance  with the  provisions  set forth in this
Article Thirteen.

                The Company hereby acknowledges that the indebtedness  evidenced
by the  Debentures  and all  Obligations of the Company under this Indenture and
the payment of any Claims with  respect to each and all of the  Debentures  will
rank  senior in right of payment to the  Company's  9%  Debentures  which may be
issued in exchange for the Convertible  Exchangeable Preferred Stock pursuant to
and in accordance  with the  Indenture,  dated as of May 1, 1997, as amended and
supplemented by the First Supplemental Indenture, dated on even date herewith.

                The term "Claim" as used herein means any claim  arising for the
rescission  of the  purchase of the  Debentures,  for damages  arising  from the
purchase of the Debentures or for  reimbursement  or  contribution on account of
such claim.

                The term "Obligations" as used herein means, with respect to any
indebtedness,  any principal,  premium, interest (including interest, whether or
not allowed,  after the filing of a petition  initiating any proceeding referred
to in Section 7.01(d) or 7.01(e)),  penalties,  commissions,  charges, expenses,
fees, indemnifications, reimbursements, and other liabilities or amounts payable
under or in respect of the documentation governing such indebtedness.

                SECTION 13.02.  Distribution  on Dissolution or  Reorganization.
(a) If, upon any  distribution,  division or  application,  partial or complete,
voluntary or involuntary,  by operation of law or otherwise,  of all or any part
of the assets of the Company  upon any  dissolution,  winding  up,  liquidation,
readjustment  or  reorganization  of the  Company  or its  property,  whether in
bankruptcy,  insolvency or receivership proceedings or at execution sale or upon
an  assignment  for the benefit of  creditors  or any other  marshalling  of the
assets and liabilities of the Company or otherwise,  then, in any such case, the
holders of all Senior Indebtedness shall first be entitled to receive payment in
full of all  Obligations  due or to become due or to become due with  respect 

                                       75


<PAGE>
to such Senior  Indebtedness  and all Claims relating thereto before the holders
of the Debentures are entitled to receive any payment or distribution on account
of any Obligations with respect to the Debentures or on account of any Claim and
until all  Obligations  with  respect  to  Senior  Indebtedness  and all  Claims
relating  thereto are paid in full, any payment or  distribution,  including any
payment or  distribution  which may be payable or  deliverable  by reason of the
payment of any other  indebtedness  of the  Company  being  subordinated  to the
payment of the  Debentures to which  Debentureholders  would be entitled but for
this Article Thirteen, shall be made to holders of Senior Indebtedness, as their
interests  may appear,  for  application  to the payment or  prepayment  of, the
Senior  Indebtedness  to the  extent  necessary  to pay in full all such  Senior
Indebtedness  and all Obligations and Claims relating thereto in accordance with
terms thereof,  after giving effect to any concurrent payment or distribution to
or for the holders of such Senior Indebtedness, except that Debentureholders may
receive shares of stock or any debt securities that are subordinated to at least
the  same  extent  as the  Debentures  to  Senior  Indebtedness.  Upon  any such
application,    dissolution,   winding   up,   liquidation,    readjustment   or
reorganization, any payment or distribution of assets of the Company of any kind
or character whether in cash, property or securities (other than shares of stock
of the Company as  reorganized or readjusted or securities of the Company or any
other corporation provided for by a plan of reorganization or readjustment,  the
payment of which is subordinated to the payment of all Senior Indebtedness which
may at the time be  outstanding)  to which the holders of the  Debentures or the
Trustee  would be entitled  except for the  provisions  of this Article shall be
paid by the Company or the  liquidating  trustee or agent or other person making
such payment or  distribution,  whether a trustee in  bankruptcy,  a receiver or
liquidating trustee or whatsoever,  direct to the holders of Senior Indebtedness
or their  representative or  representatives or to the trustee or trustees under
any  indenture  under  which  any  instruments  evidencing  any of  such  Senior
Indebtedness may have been issued,  ratably  according to the aggregate  amounts
remaining  unpaid on  account  of the  principal  of (and  premium,  if any) and
interest on the Senior  Indebtedness  held or represented by each, to the extent
necessary to pay in full all Senior Indebtedness  remaining unpaid, after giving
effect to any concurrent  payment or  distribution to the holders of such Senior
Indebtedness;  and in the event that,  notwithstanding  the foregoing,  upon any
such  application,   dissolution,  winding  up,  liquidation,   readjustment  or
reorganization, any payment or distribution of assets of the Company of any kind
or  character,  whether in cash,  property or  securities  (other than shares of
stock of the Company as  reorganized  or readjusted or securities of the Company
or  any  other  corporation   provided  for  by  a  plan  of  reorganization  or
readjustment,  the payment of which is subordinated to the payment of all Senior
Indebtedness  which may at the time be  outstanding)  shall be  received  by the
Trustee or the holders of the Debentures before all Senior  Indebtedness is paid
in full, such payment or distribution  shall be paid over to the holders of such
Senior Indebtedness or their representative or representatives or to the trustee
or trustees under any indenture  under which any  instruments  evidencing any of
such  Senior  Indebtedness  may have been  issued,  ratably  as  aforesaid,  for
application to the payment of all Senior Indebtedness remaining unpaid until all
such Senior Indebtedness shall have been paid

                                       76
<PAGE>


in full,  after giving effect to any concurrent  payment or  distribution to the
holders  of such  Senior  Indebtedness.  Subject  to the  payment in full of all
Senior Indebtedness and all Obligations and Claims relating thereto, the holders
of the  Debentures  shall be  subrogated  (equally  and  ratably  with all other
indebtedness  ranking  pari  passu  with the  Debentures)  to the  rights of the
holders of Senior  Indebtedness to receive payments or distribution of assets of
the Company applicable to the Senior Indebtedness to the extent that payments or
distributions otherwise payable to the Debentureholders have been applied to the
payment  of Senior  Indebtedness  until the  principal  of and  interest  on the
Debentures  shall be paid in full.  No such  payments  or  distributions  to the
Senior Indebtedness shall, as between the Company,  its creditors other than the
holders of Senior Indebtedness,  and the holders of the Debentures, be deemed to
be a  payment  by the  Company  to or on  account  of the  Debentures,  it being
understood  that the provisions of this Article are and are intended  solely for
the purpose of defining the relative rights of the holders of the Debentures, on
the one hand, and the holders of the Senior Indebtedness, on the other hand, and
nothing  contained  in this  Article or  elsewhere  in this  Indenture or in the
Debentures is intended to or shall impair, as between the Company, its creditors
other  than  the  holders  of  Senior  Indebtedness,  and  the  holders  of  the
Debentures,  the obligation of the Company, which is unconditional and absolute,
to pay to the holders of the  Debentures  the  principal  of and interest on the
Debentures as and when the same shall become due and payable in accordance  with
their terms,  or to affect the relative  rights of the holders of the Debentures
and creditors of the Company other than the holders of the Senior  Indebtedness,
nor shall  anything  herein or therein  prevent the Trustee or the holder of any
Debenture  from  exercising all remedies  otherwise  permitted by applicable law
upon default under this  Indenture,  subject to the rights,  if any,  under this
Article of the holders of Senior  Indebtedness  in respect of cash,  property or
securities of the Company  received  upon the exercise of any such remedy.  Upon
any  application or  distribution  of assets of the Company  referred to in this
Article, the Trustee,  subject to the provisions of Section 8.01 hereof, and the
holders of the  Debentures  shall be  entitled to rely upon a  certificate  of a
trustee in  bankruptcy,  a  receiver,  a  liquidating  trustee or agent or other
person  making  any  distribution  to  the  Trustee  or to  the  holders  of the
Debentures for the purpose of ascertaining  the persons  entitled to participate
in  such  distribution,  the  holders  of  the  Senior  Indebtedness  and  other
indebtedness of the Company,  the amount thereof or payable thereon,  the amount
or amounts paid or distributed  thereon and all other facts pertinent thereto or
to this Article.  If any payment or distribution  to which the  Debentureholders
would  otherwise  have been  entitled  but for the  provisions  of this  Article
Thirteen  shall have been  applied,  pursuant to the  provisions of this Article
Thirteen, to the payment of all amounts payable under Senior Indebtedness, then,
and in such case,  the  Debentureholders  shall be entitled to receive  from the
holders of such Senior  Indebtedness any payments or  distributions  received by
such  holders of Senior  Indebtedness  in excess of the amount  required to make
payment in full, in cash or cash  equivalents,  of such Senior  Indebtedness  of
such holders.

                (b) In the event and during the  continuation  of any default in
the payment of the  principal  of, or premium or sinking fund  installments,  if
any, or  interest  on, any

                                       77

<PAGE>

Senior Indebtedness, or any default, or any event which, with notice or lapse of
time or both,  would  constitute  a  default,  in any other  agreement,  term or
condition  contained in any  agreement  under which any Senior  Indebtedness  is
issued,  if the  effect of such  default  is to cause,  or permit  the holder or
holders of such  Senior  Indebtedness  (or a trustee on behalf of such holder or
holders) to cause,  such Senior  Indebtedness  to become due prior to its stated
maturity,  no payment or  distribution  (including  any payment or  distribution
which may be  payable  or  deliverable  by reason  of the  payment  of any other
indebtedness  of the Company  being  subordinate  to payment of the  Debentures)
shall be made on the  Debentures for or on the account of any  obligations  with
respect  to the  Debentures  or on  account  of my claim  unless  and until such
default  shall have been  remedied,  if written  notice of such  default,  or of
judicial proceedings pending with respect to such default, has been given to the
Trustee by the Company, or by any holder of Senior  Indebtedness,  nor shall any
such payment be made if after giving  effect,  as if paid, to such payment,  any
such default  would exist in the  performance  or  observance of any covenant or
agreement  of the  Company  contained  in any  agreement  under which any Senior
Indebtedness  shall have been issued or pursuant  to which  Senior  Indebtedness
shall have been  incurred.  The  Company  shall  promptly  notify the Trustee in
writing  of the  existence  of any such  default  or  event  or of any  judicial
proceedings  pending  with  respect  to any such  default.  Within 15 days after
receipt of any such notice,  the Trustee shall send notification  thereof to the
Debentureholders in the manner and to the extent provided in Section 6.04(c).

                SECTION 13.03. Payments Permitted; Knowledge of Trustee. Nothing
contained  in this  Article or  elsewhere  in this  Indenture,  or in any of the
Debentures,  shall (a)impair,  as between the Company and the  Debentureholders,
the  obligation  of the  Company,  which is absolute and  unconditional,  to pay
principal of and interest on the Debentures in accordance with their terms;  (b)
affect the  relative  rights of  Debentureholders  and  creditors of the Company
other than their  rights in relation to holders of Senior  Indebtedness,  or (c)
prevent  the  Trustee  or any  Debentureholder  from  exercising  its  available
remedies upon an Event of Default, subject to the rights of holders or owners of
Senior  Indebtedness to receive  distributions and payments otherwise payable to
Debentureholders.  The  failure to make a payment on account of any  Obligations
with  respect  to the  Debentures  by reason of any  provision  of this  Article
Thirteen  will not be  construed as  preventing  the  occurrence  of an Event of
Default.

                Without  limiting  the  generality  of  the  foregoing,  nothing
contained in this Article Thirteen will restrict the right of the Trustee or the
Debentureholders  to take any action to  declare  the  Debentures  to be due and
payable prior to their stated maturity pursuant to Section 7.01 or to pursue any
rights or remedies hereunder;  provided,  however,  that all Senior Indebtedness
then due and payable or thereafter declared to be due and payable shall first be
paid in full, in cash or cash equivalents,  before the  Debentureholders  or the
Trustee are entitled to receive any direct or indirect  payment from the Company
on account of any  Obligations  with respect to the  Debentures or on account of
any Claims.

                Notwithstanding  the provisions of this Article  Thirteen or any
other  provision of this  Indenture,  or of the  Debentures,  but subject to the
provisions of Section 7.07 and Section 8.01 of this Indenture, the Trustee shall
not be charged with knowledge of the existence of any Senior Indebtedness nor of
any default in the  payment of  principal,  premium,  if any,  sinking  funds or
interest with respect to any Senior  Indebtedness,  or of any other default with
respect to any Senior  Indebtedness,  unless  and until the  Trustee  shall have
received  written notice thereof at its corporate  trust office from the Company
or the holder or holders of such Senior Indebtedness or any trustee on behalf of
such  holders  who shall have been  certified  to be such by the  Company or who
shall have otherwise  established to the reasonable  satisfaction of the Trustee
that he is such a holder or  trustee;  nor shall the  Trustee  be  charged  with
knowledge  of the  curing or waiving  of any such  default  unless and until the
Trustee  shall have  received an  Officers'  Certificate  of the Company to such
effect. The Trustee shall not be deemed to owe any fiduciary duty to the holders
of Senior Indebtedness,  and shall not be liable to any such holder if it shall,
in the exercise of reasonable care, mistakenly pay over or distribute to holders
of Debentures,  the Company, or any other person,  moneys or assets to which any
holder of  Senior  Indebtedness  shall be  entitled  by  virtue of this  Article
Thirteen or otherwise.

                Nothing contained in this Article or elsewhere in this Indenture
or in any of the Debentures  shall prevent the application by the Trustee or any
paying agent of any moneys held by the Trustee or such paying agent in trust for
the benefit of the holders of Debentures as to which notice of redemption  shall
have been mailed or published  at least once prior to the  happening or an event
of default  specified in Section 13.02(b) to the payment of or on account of the
principal of (and premium,  if any) and interest on such Debentures,  or prevent
the  application  by the  Trustee or any paying  agent of any moneys  deposited,
prior to the  happening of any event of default  specified in Section  13.02(b),
