                   SUBJECT TO COMPLETION, DATED JUNE 27, 1997

                            DATA GENERAL CORPORATION

   $212,750,000 Principal Amount of 6% Convertible Subordinated Notes due 2004

                    (Interest Payable May 15 and November 15)

                        8,122,089 Shares of Common Stock



             This Prospectus  relates to (i)  $212,750,000  aggregate  principal
amount of 6%  Convertible  Subordinated  Notes due 2004  (the  "Notes")  of Data
General  Corporation,  a Delaware corporation ("Data General" or the "Company"),
and (ii) 8,122,089 shares of common stock, par value $.01 per share (the "Common
Stock"),  of the Company  which are initially  issuable  upon  conversion of the
Notes plus such additional indeterminate number of shares of Common Stock as may
become  issuable upon  conversion of the Notes as a result of adjustments to the
conversion  price  (the  "Shares").  The  Notes  and the  Shares  that are being
registered  hereby are to be offered for the account of the holders thereof (the
"Selling  Securityholders").  The Notes were initially acquired from the Company
by Morgan Stanley & Co.  Incorporated and Dillon,  Read & Co. Inc. (the "Initial
Purchasers") in May 1997 in connection with a private offering. See "Description
of the Notes."

             The Notes are  convertible  into Common Stock of the Company at any
time  after  90 days  following  the  original  issuance  thereof  and  prior to
maturity,  unless  previously  redeemed,  at a  conversion  price of $26.194 per
share,  subject to adjustment in certain events. The reported last sale price of
the Common Stock on the New York Stock  Exchange on June 26,  1997, was $25.875
per share. The Common Stock is traded under the symbol "DGN."

             The Notes are not  redeemable by the Company prior to May 18, 2000.
Subject  to the  foregoing,  the Notes will be  redeemable  on at least 30 days'
prior notice at the option of the Company,  in whole or in part, at any time, at
the redemption  prices set forth in this Prospectus,  in each case together with
accrued interest.  The Notes may also be redeemed at the option of the holder if
there is a  Fundamental  Change  (as  defined  herein) at  declining  redemption
prices, subject to adjustment in certain events as defined herein, together with
accrued  interest.  See  "Description  of Notes --  Optional  Redemption  by the
Company" and "Description of Notes -- Redemption at Option of the Holder."

             The  Notes  are   unsecured   obligations   of  the  Company,   are
subordinated  to the extent provided in the Indenture (as defined herein) to the
payment in full of all Senior  Indebtedness  (as  defined  herein)  and are pari
passu in right of payment  with the  Company's 7 3/4%  Convertible  Subordinated
Debentures due 2001.  There are no restrictions in the Indenture on the creation
of  additional  Senior  Indebtedness  or  other  indebtedness.   The  Notes  are
structurally  subordinated to the liabilities,  including trade payables, of the
Company's subsidiaries.  At March 29, 1997, the Company's subsidiaries had other
indebtedness   and   liabilities  of   approximately   $89  million   (excluding
intercompany obligations).  See "Description of Notes -- Subordination of Notes"
and "Risk Factors."

             The  Notes are  eligible  for  trading  in the  Private  Offerings,
Resales and Trading through Automated  Linkages  ("PORTAL")  Market. The Initial
Purchasers  have advised the Company that they are currently  making a market in
the Notes. The Initial Purchasers,  however,  are not obligated to do so and any
such market making may be discontinued  at any time without notice,  in the sole
discretion of the Initial Purchasers.  No assurance can be given that any market
for the Notes will be maintained.

             The Notes and the  Shares  are being  registered  to permit  public
secondary  trading of the Notes and,  upon  conversion,  the  underlying  Common
Stock,  by the  holders  thereof  from  time  to  time  after  the  date of this
Prospectus.  For a description of certain income tax  consequences to holders of
the Notes,  see "Certain  Federal  Income Tax  Considerations."  The Company has
agreed,  among  other  things,  to bear all  expenses  in  connection  with this
registration statement.

             The  Company  will not receive  any of the  proceeds  from sales of
Notes or the Shares by the Selling Securityholders. The Notes and the Shares may
be offered  from time to time by the Selling  Securityholders  (and their donees
and  pledgees)  in  negotiated  transactions  or  otherwise,  at  market  prices
prevailing  at  the  time  of  sale  or  at  negotiated  prices.  See  "Plan  of
Distribution." The Selling Securityholders may be deemed to be "underwriters" as
defined in the Securities Act of 1933, as amended (the "Securities Act"). If any
broker-dealers are used by the Selling Securityholders,  any commissions paid to
broker-dealers   and,  if  broker-dealers   purchase  any  Notes  or  Shares  as
principals,  any profits  received by such  broker-dealers  on the resale of the
Notes or Shares may be deemed to be underwriting  discounts or commissions under
the  Securities  Act.  In  addition,   any  profits   realized  by  the  Selling
Securityholders may be deemed to be underwriting commissions.

     SEE "RISK FACTORS" BEGINNING ON PAGE 4 FOR A DESCRIPTION OF CERTAIN FACTORS
THAT SHOULD BE CONSIDERED BY PROSPECTIVE INVESTORS.

    THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
         AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR

         The Company has two main  product  lines,  AViiON(R)  and  CLARiiON(R),
which accounted in the aggregate for  approximately  89% of product  revenues in
the six-month period ended March 29, 1997. AViiON computers  function as servers
and multi-user systems for a wide variety of applications,  providing  solutions
for businesses ranging from departments and small businesses to large commercial

users,  handle  large  volumes of  transactions  and  support  large  databases.
Approximately  40,000 AViiON systems have been shipped since 1989. The Company's

                                  RISK FACTORS

         This Prospectus contains certain forward-looking  statements within the
meaning of Section 27A of the  Securities  Act and  Section 21E of the  Exchange
Act. Actual results could differ materially from those projected or contemplated
in the forward-looking statements as a result of certain of the risk factors set
forth below and incorporated by reference in this Prospectus. In addition to the
other  information  contained and  incorporated by reference in this Prospectus,
the  following  risk factors  should be considered  carefully in evaluating  the
Company and its business before purchasing the Notes or the Shares.

Changing Technologies

         To compete  effectively  in the server and mass  storage  markets,  the
Company must  continue to introduce  new products and features  that address the
needs and preferences of its target markets.  The server and storage markets are
characterized  by short  development  cycles that are driven by rapidly changing
technology as well as declining  product prices.  There can be no assurance that
the Company  will be able to  continue to  introduce  new  competitively  priced
products, that the market will be receptive to its products or features, or that
competitors will not introduce advancements ahead of Data General.  Furthermore,
there can be no  assurance  that the Company  will develop or have access to new
competitive  technology  to permit it to introduce new products and features for
its target markets. In addition,  the Company must make strategic decisions from
time to time as to which new  technologies  will result in products  for sale to
markets that will experience future growth, and must form and maintain strategic
alliances for the design and  marketing of its  products.  If the Company is
                                      -4-

<PAGE>

not  successful in continuing to introduce new products in the growing  segments
of the market or in forming and maintaining  critical  strategic  relationships,
there could be a material  adverse effect on the Company's  business,  financial
condition and results of operations.

Dependence on Suppliers

         Certain  components  and products that meet the Company's  requirements
are  available  only from a single  supplier or a limited  number of  suppliers.
Among those components are disk drives,  microprocessors and certain proprietary
integrated circuits.  The rapid rate of technological  change, and the necessity
of developing and  manufacturing  products with short  life-cycles may intensify
these risks. The inability to obtain components and products as required,  or to
develop  alternative  sources if and as required in the future,  could result in
delays or reductions in product  shipments,  which in turn could have a material
adverse  effect on the Company's  business,  financial  condition and results of
operations.

Indirect Channels of Distribution

         Substantially  all of the Company's  CLARiiON sales,  and a significant
portion of the  Company's  AViiON  sales,  are  derived  from  reseller  and OEM
channels.  A single  CLARiiON OEM channel  customer during fiscal 1996 accounted
for  approximately  15% of the Company's  consolidated  revenues.  The Company's
business,  financial  condition  and results of  operations  could be  adversely
affected  if  this  customer  or any  other  material  reseller  or OEM  were to
substantially  decrease  its  orders  or  terminate  its  relationship  with the
Company.  Further, the utilization of indirect channels of distribution tends to
limit the Company's ability to predict customer orders.

Concentrated Manufacturing Operations

         Over the last several years,  the Company has  consolidated its various
manufacturing   operations   into  three   facilities.   As  a  result  of  this
consolidation,  most of the  Company's  assembly,  test and systems  integration
operations  are performed at its Apex,  North Carolina  facility.  The Company's
ability to ship products and the  Company's  business,  financial  condition and
results of  operations  could be adversely  affected  were the Apex facility not
able to operate at required levels.

Capitalization of Software Development Costs

         The Company has made and continues to make  significant  investments in
software  development  efforts.  The amount of  expenditures  that  qualify  for
capitalization   under  Statement  of  Financial  Accounting  Standards  No.  86
"Accounting for the Costs of Computer Software to Be Sold,  Leased, or Otherwise
Marketed" may vary from period to period as software  projects  progress through
the  development  life-cycle.   These  variations  could  impact  the  Company's
operating results in any given period.  Unamortized  software  development costs
were approximately $67 million at March 29, 1997. If technological  developments
or other  factors were to  jeopardize  the  realizability  of such  assets,  the
Company  could be  required  to write off all or a  substantial  portion of such
capitalized values,  which would have a material adverse effect on the Company's
results of operations for the period in which the write-off occurred.

Subordination

The Notes are  unsecured  and  subordinated  in right of  payment in full to all
existing and future  Senior  Indebtedness  of the  Company.  As a result of such
subordination, in the event of bankruptcy,  liquidation or reorganization of the
Company or upon acceleration of the Notes due to an event of default, the assets
of the Company would be available to pay obligations on the Notes only after all
Senior Indebtedness had been paid in full, and there
                                       -5-

<PAGE>

might not be sufficient assets remaining to pay amounts due on any or all of the
Notes  then  outstanding.   The  Notes  are  structurally  subordinated  to  the
liabilities,  including  trade  payables,  of the  Company's  subsidiaries.  The
Indenture  does not prohibit or limit the incurrence of Senior  Indebtedness  or
the incurrence of other indebtedness and other liabilities by the Company or its
subsidiaries,   and  the  incurrence  of  additional   indebtedness   and  other
liabilities  by the  Company  or its  subsidiaries  could  adversely  affect the
Company's  ability to pay its  obligations on the Notes.  At March 29, 1997, the
Company  had  approximately  $28  million  of  outstanding  Senior  Indebtedness
consisting  of  approximately  $23 million of the  Company's 8 3/8% Sinking Fund
Debentures  due 2002 and  approximately  $5 million of contingent  reimbursement
obligations under outstanding  letters of credit.  Subsequent to March 29, 1997,
the Company  retired the  outstanding 8 3/8% Sinking Fund  Debentures by using a
portion of the proceeds of the sale of the Notes to the Initial  Purchasers.  At
March  29,  1997,  the  Company's   subsidiaries  had  other   indebtedness  and
liabilities of approximately $89 million (excluding  intercompany  obligations).
The  Company  anticipates  that  from  time to time  it  will  incur  additional
indebtedness,  including Senior  Indebtedness,  and that it and its subsidiaries
will from time to time incur other additional indebtedness and liabilities.  See
"Description of Notes -- Subordination of Notes" and "Use of Proceeds."

Limitations on Redemption of Notes

         Upon a  Fundamental  Change,  each  holder of Notes  will have  certain
rights,  at the  holder's  option,  to  require  the  Company to redeem all or a
portion of such holder's Notes. If a Fundamental Change were to occur, there can
be no  assurance  that  the  Company  would  have  sufficient  funds  to pay the
redemption price for all Notes tendered.  Any future credit  agreements or other
agreements  (including  those  relating  to  Senior  Indebtedness)  may  contain
provisions  restricting  the purchase or redemption of the Notes. In the event a
Fundamental  Change  occurs  at a time  when  the  Company  is  prohibited  from
purchasing  or redeeming  the Notes,  the Company  could seek the consent of its
lenders  to the  purchase  of the  Notes  or  could  attempt  to  refinance  the
borrowings that contain such prohibition.  If the Company does not obtain such a
consent or repay such  borrowings,  the Company  would  remain  prohibited  from
purchasing or redeeming  Notes.  In such case,  the Company's  failure to redeem
tendered Notes would  constitute an Event of Default under the Indenture,  which
might, in turn,  constitute a default under the terms of agreements  relating to
other  indebtedness  that the company may enter into from time to time.  In such
circumstances,  the  subordination  provisions  in the  Indenture  would  likely
restrict  payments to the  holders of the Notes.  See  "Description  of Notes --
Redemption at Option of the Holder."

Absence of Public Market for the Notes and Restrictions on Resale

         The Notes are eligible for trading through the PORTAL market.  Although
the Initial  Purchasers are currently making a market in the Notes, they are not
obligated to do so and may  discontinue  such market  making at any time without
notice.  In  addition,  such  market  making  activity  is subject to the limits
imposed by the Securities Act and the Exchange Act. Accordingly, there can be no
assurance that any market for the Notes will be maintained.  If an active market
for the Notes fails to be  sustained,  the trading  price of such Notes could be
materially adversely affected.  The Company does not intend to apply for listing
of the Notes on any securities exchange.

Other Risks

         Without  limitation  of  the  foregoing,   the  Company  makes  further
reference to those risks and cautions stated on Pages 9 through 11 of its Annual
Report on Form 10-K for the fiscal year ended  September 28, 1996, as filed with
the Commission, which is incorporated herein by reference.

         The ratio of  earnings to fixed  charges is computed by dividing  fixed
charges into  earnings  before  income taxes plus fixed  charges.  Fixed charges
consist of  interest on all  indebtedness,  including  amortization  of original
issue  discount  and issue costs  related to  outstanding  long-term  debt,  and
one-third of all rental  expense  (being deemed by management to be a reasonable
approximation  of the interest factor in rental  expense). 

                                 USE OF PROCEEDS

         The  Company  will not receive  any of the  proceeds  from sales of the
Notes or the Shares by the Selling Securityholders.

                             SELLING SECURITYHOLDERS

         The Notes were  originally  acquired  from the  Company by the  Initial
Purchasers on May 21, 1997. The Initial Purchasers have advised the Company that
the  Initial  Purchasers  resold  the  Notes  in  transactions  exempt  from the
registration  requirements  of the  Securities  Act to "qualified  institutional
buyers"  (as  defined  in Rule 144A of the  Securities  Act).  These  subsequent
purchasers, or their transferees,  pledgees, donees or successors, may from time
to time offer and sell any or all of the Notes  and/or  Shares  pursuant to this
Prospectus.

         The  Notes  and  the  Shares  are  being  registered  pursuant  to  the
Registration  Rights Agreement,  dated May 21, 1997, between the Company and the
Initial Purchasers (the "Registration Rights Agreement") which provides that the
Company file the Registration  Statement with regard to the Notes and the Shares
within  60 days of the date of  original  issuance  of the  Notes  and keep such
Registration  Statement  effective until the earlier of (i) the sale pursuant to
the Registration  Statement of all the securities registered thereunder and (ii)
the expiration of the holding period  applicable to such  securities  under Rule
144(k) under the Securities Act or any successor provision. Although none of the
Selling  Securityholders  has advised the Company that it  currently  intends to
sell all or any of the Notes or Shares pursuant to this Prospectus,  the Selling
Securityholders  may choose to sell the Notes  and/or  Shares  from time to time
upon notice to the Company. See "Plan of Distribution."

         Prior to any use of this  Prospectus in connection  with an offering of
the Notes and/or Shares,  this  Prospectus will be supplemented to set forth the
name and  number  of shares  beneficially  owned by the  Selling  Securityholder
intending to sell such Notes and/or Shares and the number of Notes and/or Shares
to be offered. The Prospectus  Supplement will also disclose whether any Selling
Securityholder  selling in connection with such  Prospectus  Supplement has held
any position or office with,  been  employed by or otherwise  has had a material
relationship  with, the Company or any of its affiliates  during the three years
prior to the date of the Prospectus Supplement.

<PAGE>

                              PLAN OF DISTRIBUTION

         The  Notes  and the  Shares  are  being  registered  to  permit  public
secondary  trading of such  securities by the holders  thereof from time to time
after the date of this Prospectus.  The Company has agreed,  among other things,
to bear all expenses in connection with the  registration  and sale of the Notes
and the Shares covered by this Prospectus.

         The Company will not receive any of the  proceeds  from the offering of
Notes and the Shares by the Selling Securityholders. The Selling Securityholders
(and  their  donees  and  pledgees)  may sell all or a portion  of the Notes and
Shares  beneficially  owned by them and offered  hereby from time to time on any
exchange on which the  securities  are listed on terms to be  determined  at the
times of such sales.  The Selling  Securityholders  may also make private  sales
directly  or  through a broker or  brokers.  Alternatively,  any of the  Selling
Securityholders  may from time to time  offer  the Notes or Shares  beneficially
owned  by  them  through  underwriters,  dealers  or  agents,  who  may  receive
compensation in the form of underwriting  discounts,  commissions or concessions
from the Selling  Securityholders  and the purchasers of the Notes or Shares for
whom  they  may  act  as  agent.   The   aggregate   proceeds   to  the  Selling
Securityholders from the sale of the Notes or Shares offered by them hereby will
be the purchase price of such Notes or Shares less discounts and commissions, if
any.

         The Notes and the  Shares  may be sold from time to time in one or more
transactions  at fixed  offering  prices,  which may be  changed,  or at varying
prices determined at the time of sale or at negotiated prices.  Such prices will
be  determined by the holders of such  securities  or by agreement  between such
holders  and  underwriters  or dealers who may receive  fees or  commissions  in
connection therewith.

         The  outstanding  Common Stock is publicly traded on the New York Stock
Exchange  (the  "Exchange"),  and the Shares have been approved for listing upon
official notice of issuance.  The Initial  Purchasers are making a market in the
Notes;  however,  they are not obligated to do so and any such market-making may
be  discontinued  at any time  without  notice,  in the sole  discretion  of the
Initial  Purchasers.  The  Company  does not intend to apply for  listing of the
Notes on any securities exchange.  Accordingly,  no assurance can be given as to
the  development  or  liquidity  of any trading  market that may develop for the
Notes.

         The  Selling   Securityholders  and  any   broker-dealers,   agents  or
underwriters   that  participate  with  the  Selling   Securityholders   in  the
distribution  of the Notes or the  Shares  may be  deemed  to be  "underwriters"
within  the  meaning  of the  Securities  Act,  in which  event any  commissions
received by such broker-dealer,  agents or underwriters and any profits realized
by the  Selling  Securityholders  on the  resales  of the  Notes  or the  shares
purchased by them may be deemed to be underwriting commissions or discount under
the Securities Act.

         In addition,  any securities  covered by this Prospectus  which qualify
for sale pursuant to Rule 144, Rule 144A or any other  available  exemption from
registration  under the  Securities Act may be sold under Rule 144, Rule 144A or
such other available exemption rather than pursuant to this Prospectus. There is
no assurance that any Selling  Securityholder  will sell any or all of the Notes
or Shares described herein, and any Selling Securityholder may transfer,  devise
or gift such securities by other means not described herein.

         The Notes were originally sold by the Company to the Initial Purchasers
in May 1997 in a private placement. The Company agreed to indemnify and hold the
Initial Purchasers harmless against certain liabilities under the Securities Act
that  could  arise  in  connection  with the  sale of the  Notes by the  Initial
Purchasers.  The Registration  Rights Agreement provides for the Company and the
Selling  Securityholders  to indemnify  each other against  certain  liabilities
arising under the Securities Act.
                                      -8-

<PAGE>

         The  Company  has  agreed  to  use  reasonable   efforts  to  keep  the
Registration  Statement to which this  Prospectus  relates  effective  until the
earlier  of (i) the  sale  pursuant  to the  Registration  Statement  of all the
securities  registered  thereunder and (ii) the expiration of the holding period
applicable to such securities  under Rule 144(k) under the Securities Act or any
successor provision. The Registration Rights Agreement provides that the Company
may suspend the use of this Prospectus in connection with the sales of Notes and
Shares by holders for a period not to exceed 30 days in any three-month  period,
or not to exceed an aggregate of 60 days in any 12-month  period,  under certain
circumstances  relating to pending corporate  developments,  public filings with
the Commission and similar events.  The Company has agreed to pay  predetermined
liquidated damages to those Selling  Securityholders  who have requested to sell
pursuant to the  Registration  Statement  if the  Registration  Statement is not
timely filed or if this Prospectus is unavailable for periods in excess of those
permitted  above.  The Company has further  agreed,  if such  failure to file or
unavailability   continues  for  an  additional   thirty-day   period,   to  pay
predetermined liquidated damages to all Selling Securityholders,  whether or not
such  holder has  requested  to sell  pursuant  to the  Registration  Statement.
Expenses  of  preparing   and  filing  the   Registration   Statement   and  all
post-effective amendments will be borne by the Company.


                              DESCRIPTION OF NOTES

         The Notes were issued under an indenture, dated as of May 21, 1997 (the
"Indenture"),  between  the Company  and The Bank of New York,  as trustee  (the
"Trustee").  Copies of the  Indenture  and  Registration  Rights  Agreement  are
available from the Trustee upon request by a registered holder of the Notes. The
following  summaries of certain  provisions of the Notes,  the Indenture and the
Registration  Rights  Agreement  (which have been filed with the  Commission  as
Exhibits 4.3, 4.2 and 4.4, respectively,  to the Registration Statement of which
this Prospectus is a part) do not purport to be complete and are subject to, and
are  qualified in their  entirety by  reference  to, all the  provisions  of the
Notes,  the  Indenture  and the  Registration  Rights  Agreement,  including the
definitions  therein of certain  terms which are not  otherwise  defined in this
Prospectus. Wherever particular provisions or defined terms of the Indenture (or
of the  Form of  Notes  which  is a part  thereof)  or the  Registration  Rights
Agreement are referred to, such  provisions  or defined  terms are  incorporated
herein by reference.

General

         The  Notes  represent  unsecured  general  obligations  of the  Company
subordinate  in right of payment to certain other  obligations of the Company as
described under  "Subordination  of Notes" and convertible  into Common Stock as
described  under  "Conversion  of Notes."  The Notes rank pari passu in right of
payment with the Company's 7 3/4% Convertible  Subordinated Debentures due 2001.
The Notes are limited to $212,750,000  aggregate  principal amount, are issuable
only in  denominations  of $1,000 or any multiple thereof and will mature on May
15, 2004,  unless earlier redeemed at the option of the Company or at the option
of the holder upon a Fundamental Change (as defined below).

         The Indenture does not contain any financial  covenants or restrictions
on the payment of dividends,  the incurrence of Senior  Indebtedness (as defined
below  under  "Subordination  of  Notes")  or  the  issuance  or  repurchase  of
securities  of the  Company.  The  Indenture  contains  no  covenants  or  other
provisions to afford protection to holders of the Notes in the event of a highly
leveraged transaction or a change in control of the Company except to the extent
described under "Redemption at Option of the Holder."

         The Notes bear  interest  at the annual  rate of 6% from May 21,  1997,
payable  semi-annually  on May 15 and  November 15,  commencing  on November 15,
1997,  to holders of record at the close of business on the  preceding  April 30
and  October  31,  respectively,  except  (i) that
                                      -9-
<PAGE>

the  interest  payment  upon  redemption  (unless the date of  redemption  is an
interest  payment  date)  will be payable  to the  person to whom  principal  is
payable and (ii) as set forth in the next  succeeding  sentence.  In the case of
any Note (or  portion  thereof)  which is  converted  into  Common  Stock of the
Company during the period from (but  excluding) a record date to (but excluding)
the next  succeeding  interest  payment date either (i) if such Note (or portion
thereof) has been called for redemption on a redemption date which occurs during
such period,  or is to be redeemed in connection with a Fundamental  Change on a
Repurchase Date (as defined below) which occurs during such period,  the Company
shall not be required to pay interest on such  interest  payment date in respect
of any such Note (or portion thereof) or (ii) if otherwise, any Note (or portion
thereof)  submitted for  conversion  during such period shall be  accompanied by
funds equal to the interest payable on such succeeding  interest payment date on
the principal  amount so converted (see  "Conversion of Notes" below).  Interest
may, at the Company's  option, be paid either (i) by check mailed to the address
of the person  entitled  thereto as it appears in the Note  register  or (ii) by
transfer to an account  maintained by such person  located in the United States;
provided,  however, that payments to The Depository Trust Company, New York, New
York ("DTC") will be made by wire transfer of immediately available funds to the
account  of DTC or its  nominee.  Interest  will be  computed  on the basis of a
360-day year composed of twelve 30-day months.

Form, Denomination and Registration

         The Notes are issuable in fully  registered form,  without coupons,  in
denominations of $1,000 principal amount and multiples thereof.

         Global  Note,  Book-Entry  Form.  The  Notes  offered  hereby  will  be
evidenced  by a global  Note  (the  "Registered  Global  Note"),  which  will be
deposited  with, or on behalf of, DTC, and  registered in the name of Cede & Co.
("Cede") as DTC's nominee. Except as set forth below, the Registered Global Note
may be transferred,  in whole or in part, only to another nominee of DTC or to a
successor of DTC or its nominee.

         Purchasers of the Notes offered hereby may hold their  interests in the
Registered Global Note directly through DTC or indirectly through  organizations
which  are  participants  in  DTC  (the   "Participants").   Transfers   between
Participants  will be effected in the ordinary way in accordance  with DTC rules
and will be settled in clearing house funds.

         Persons who are not  Participants may beneficially own interests in the
Registered  Global Note held by DTC only through  Participants or certain banks,
brokers,  dealers,  trust  companies  and other  parties  that clear  through or
maintain  a  custodial  relationship  with a  Participant,  either  directly  or
indirectly ("Indirect Participants"). So long as Cede, as the nominee of DTC, is
the registered  owner of the Registered  Global Note, Cede for all purposes will
be considered the sole holder of the Registered  Global Note. Except as provided
below,  owners of beneficial  interests in the  Registered  Global Note will not
have certificates  registered in their names, will not receive physical delivery
of  certificates  in definitive  form,  and will not be  considered  the holders
thereof.

         Payment  of  interest  on and the  redemption  price of the  Registered
Global Note will be made to Cede, the nominee for DTC, as the  registered  owner
of the Registered Global Note by wire transfer of immediately available funds on
each interest  payment date or the redemption  date, as the case may be. Neither
the Company,  the Trustee nor any paying agent will have any  responsibility  or
liability for any aspect of the records  relating to or payments made on account
of  beneficial  ownership  interests  in  the  Registered  Global  Note  or  for
maintaining,  supervising or reviewing any records  relating to such  beneficial
ownership interests.

         The Company has been informed by DTC that,  with respect to any payment
of interest on, or the redemption  price of, the Registered  Global Note,  DTC's
practice is to credit  Participants'  accounts on the payment date therefor with
payments in amounts  proportionate
                                      -10-
<PAGE>

to their respective  beneficial interests in the principal amount represented by
the Registered Global Note as shown on the records of DTC, unless DTC has reason
to  believe  that  it  will  not  receive  payment  on such  date.  Payments  by
Participants  to  owners  of  beneficial   interests  in  the  principal  amount
represented by the Registered Global Note held through such Participants will be
the responsibility of such Participants, as is now the case with securities held
for the accounts of customers registered in "street name."

         Because DTC can only act on behalf of Participants,  who in turn act on
behalf of  Indirect  Participants  and  certain  banks,  the ability of a person
having  a  beneficial  interest  in  the  principal  amount  represented  by the
Registered  Global Note to pledge such  interest to persons or entities  that do
not participate in the DTC system,  or otherwise take actions in respect of such
interest,  may be affected by the lack of a physical certificate evidencing such
interest.

         Neither the Company nor the Trustee (or any registrar,  paying agent or
conversion  agent  under the  Indenture)  will have any  responsibility  for the
performance  by  DTC or its  Participants  or  Indirect  Participants  of  their
respective   obligations   under  the  rules  and  procedures   governing  their
operations.  DTC has advised the Company that it will take any action  permitted
to  be  taken  by  a  holder  of  Notes  (including,   without  limitation,  the
presentation of Notes for exchange as described below), only at the direction of
one or more  Participants  to whose account with DTC interests in the Registered
Global Note are  credited,  and only in respect of the  principal  amount of the
Notes  represented by the Registered Global Note as to which such Participant or
Participants has or have given such direction.

         DTC has advised the Company as follows:  DTC is a limited purpose trust
company  organized  under the New York  Banking  Law, a  "banking  organization"
within the meaning of the New York Banking Law, a member of the Federal  Reserve
System,  a "clearing  corporation"  within the  meaning of the New York  Uniform
Commercial Code and a "clearing agency" registered pursuant to the provisions of
Section 17A of the Exchange  Act.  DTC holds  securities  that its  Participants
deposit  with  DTC.  DTC  also  facilitates  the  clearance  and  settlement  of
securities  transactions  between  Participants  through  electronic  book-entry
changes to the accounts of its  Participants,  thereby  eliminating the need for
physical movement of certificates.  Participants  include securities brokers and
dealers,  banks,  trust  companies  and  clearing  corporations  and may include
certain  other  organizations  such as the Initial  Purchasers.  Certain of such
Participants (or their representatives),  together with other entities, own DTC.
Indirect access to the DTC system is available to others such as banks, brokers,
dealers  and trust  companies  that  clear  through,  or  maintain  a  custodial
relationship with, a Participant, either directly or indirectly.

         Although  DTC has  agreed  to the  foregoing  procedures  in  order  to
facilitate   transfers  of  interests  in  the  Registered   Global  Note  among
Participants,  it is under no  obligation to perform or continue to perform such
procedures,  and such  procedures may be  discontinued at any time. If DTC is at
any  time  unwilling  or  unable  to  continue  as  depositary  and a  successor
depositary  is not  appointed  by the Company  within 90 days,  the Company will
cause  Notes to be issued in  definitive  form in  exchange  for the  Registered
Global Note.

         Certificated  Notes.  Holders of Notes may  request  that  certificated
Notes be issued in exchange for Notes represented by the Registered Global Note.
Furthermore,  certificated Notes may be issued in exchange for Notes represented
by the Registered Global Note if no successor is appointed by the Company as set
forth above under "Global Note, Book-Entry Form."

Conversion of Notes

         The holders of Notes are  entitled at any time after 90 days  following
the date of original issuance thereof through the close of business on the final
maturity date of the Notes, subject to prior redemption, to convert any Notes or
portions thereof (in  denominations of $1,000 or 
                                      -11-

multiples thereof) into Common Stock of the Company,  at the conversion price of
$26.194.  Except as described below, no payment or other adjustment will be made
on conversion of any Notes for interest  accrued thereon or for dividends on any
Common Stock issued.  If any Notes not called for redemption are converted after
a record  date for the  payment  of  interest  and prior to the next  succeeding
interest  payment  date,  such Notes must be  accompanied  by funds equal to the
interest  payable on such  succeeding  interest  payment  date on the  principal
amount so converted.  The Company is not required to issue fractional  shares of
Common  Stock upon  conversion  of Notes and, in lieu  thereof,  will pay a cash
adjustment  based upon the market price of Common Stock on the last business day
prior to the date of  conversion.  In the case of Notes  called for  redemption,
conversion  rights  will expire at the close of  business  on the  business  day
preceding  the day fixed for  redemption  unless  the  Company  defaults  in the
payment  of the  redemption  price.  A Note in  respect  of  which a  holder  is
exercising  its option to require  redemption  upon a Fundamental  Change may be
converted  only if such holder  withdraws its election to exercise its option in
accordance with the terms of the Indenture.

         The initial  conversion  price of $26.194 per share of Common  Stock is
subject to  adjustment  under  formulae as set forth in the Indenture in certain
events, including:

                  (i) the  issuance of Common Stock of the Company as a dividend
         or distribution on the Common Stock;

                  (ii)  certain  subdivisions  and  combinations  of the  Common
         Stock;

                  (iii) the  issuance to all holders of Common  Stock of certain
         rights or warrants to purchase Common Stock;

                  (iv)  the  distribution  to all  holders  of  Common  Stock of
         capital stock (other than Common Stock),  of evidences of  indebtedness
         of the Company or of assets (including securities,  but excluding those
         rights, warrants, dividends and distributions referred to above or paid
         in cash);

                  (v) distributions  consisting of cash, excluding any quarterly
         cash dividend on the Common Stock to the extent that the aggregate cash
         dividend  per share of Common  Stock in any quarter does not exceed the
         greater  of (x) the  amount  per  share  of  Common  Stock  of the next
         preceding  quarterly  cash  dividend on the Common  Stock to the extent
         that such preceding quarterly dividend did not require an adjustment of
         the  conversion  price  pursuant  to this  clause (v) (as  adjusted  to
         reflect subdivisions or combinations of the Common Stock), and (y) 3.75
         percent of the average of the last  reported  sales price of the Common
         Stock  during the ten  trading  days  immediately  prior to the date of
         declaration   of  such   dividend,   and   excluding  any  dividend  or
         distribution in connection with the liquidation, dissolution or winding
         up of the Company. If an adjustment is required to be made as set forth
         in this  clause (v) as a result of a  distribution  that is a quarterly
         dividend,  such adjustment would be based upon the amount by which such
         distribution exceeds the amount of the quarterly cash divided permitted
         to be  excluded  pursuant  to this  clause  (v).  If an  adjustment  is
         required  to be made as set forth in this  clause  (v) as a result of a
         distribution that is not a quarterly dividend, such adjustment would be
         based upon the full amount of the distribution;

                  (vi) payment in respect of a tender offer or exchange offer by
         the Company or any  subsidiary  of the Company for the Common  Stock to
         the extent that the cash and value of any other consideration  included
         in such  payment per share of Common Stock  exceeds the Current  Market
         Price (as defined in the  Indenture)  per share of Common  Stock on the
         trading day next succeeding the last date on which tenders or exchanges
         may be made pursuant to such tender or exchange offer; and
                                      -12-
<PAGE>

                  (vii)  payment in respect of a tender offer or exchange  offer
         by a person other than the Company or any  subsidiary of the Company in
         which,  as of the closing date of the offer,  the Board of Directors is
         not recommending  rejection of the offer. The adjustment referred to in
         this  clause  (vii) will only be made if the tender  offer or  exchange
         offer is for an amount  which  increases  the  offeror's  ownership  of
         Common  Stock to more  than 25% of the total  shares  of  Common  Stock
         outstanding,  and if the cash  and  value  of any  other  consideration
         included in such payment per share of Common Stock  exceeds the Current
         Market  Price  per  share  of  Common  Stock on the  business  day next
         succeeding  the last date on which  tenders  or  exchanges  may be made
         pursuant to such tender or exchange offer.  The adjustment  referred to
         in this clause (vii) will generally not be made, however, if, as of the
         closing of the offer, the offering documents with respect to such offer
         disclose  a plan or an  intention  to cause the  Company to engage in a
         consolidation   or  merger  of  the   Company  or  a  sale  of  all  or
         substantially all of the Company's assets.

           In the case of (i) any  reclassification of the Common Stock, or (ii)
a  consolidation,  merger or  combination  involving  the  Company  or a sale or
conveyance  to another  person of the  property  and assets of the Company as an
entirety  or  substantially  as an  entirety,  in each case as a result of which
holders of Common Stock shall be entitled to receive  stock,  other  securities,
other  property or assets  (including  cash) with  respect to or in exchange for
such Common Stock,  the holders of the Notes then  outstanding will generally be
entitled  thereafter to convert such Notes into the kind and amount of shares of
stock,  other securities or other property or assets which they would have owned
or been entitled to receive upon such reclassification,  change,  consolidation,
merger,  combination,  sale or  conveyance  had such Notes been  converted  into
Common Stock immediately prior to such reclassification,  consolidation, merger,
combination,  sale or conveyance  assuming that a holder of Notes would not have
exercised  any rights of election  as to the stock,  other  securities  or other
property or assets receivable in connection therewith.

           In the event of a taxable  distribution to holders of Common Stock or
in certain other  circumstances  requiring  conversion  price  adjustments,  the
holders of Notes may,  in certain  circumstances,  be deemed to have  received a
distribution subject to United States income tax as a dividend; in certain other
circumstances,  the  absence  of such an  adjustment  may  result  in a  taxable
dividend  to the  holders  of Common  Stock.  See  "Certain  Federal  Income Tax
Considerations" below.

           The  Company  from time to time may to the  extent  permitted  by law
reduce the conversion price by any amount for any period of at least 20 days, in
which case the Company shall give at least 15 days' notice of such reduction, if
the Board of Directors has made a determination  that such reduction would be in
the best interests of the Company, which determination shall be conclusive.  The
Company may, at its option,  make such  reductions in the conversion  price,  in
addition to those set forth above,  as the Board of Directors deems advisable to
avoid or diminish  any income tax to holder of Common Stock  resulting  from any
dividend or distribution of stock (or rights to acquire stock) or from any event
treated  as such for  income  tax  purposes.  See  "Certain  Federal  Income Tax
Considerations."

           No adjustment in the  conversion  price will be required  unless such
adjustment would require a change of at least 1% in the conversion price then in
effect; provided that any adjustment that would otherwise be required to be made
shall be carried  forward and taken into account in any  subsequent  adjustment.
Except as stated  above,  the  conversion  price  will not be  adjusted  for the
issuance of Common Stock or any securities  convertible into or exchangeable for
Common Stock or carrying the right to purchase any of the foregoing.

Optional Redemption by the Company

           The Notes are not  entitled  to any sinking  fund.  At any time on or
after May 18, 2000,  the Notes will be redeemable at the Company's  option on at
least 30 days' notice as a whole or, from time to time, in part at the following
prices (expressed as percentages of the principal amount), together with accrued
interest to and including the date fixed for redemption:

        If redeemed  during the period  beginning May 18, 2000 and ending on May
        14, 2001 at a redemption  price of 103.429%,  and if redeemed during the
        12-month period beginning May 15:


                                                                     Redemption
          Year                                                          Price
          ----                                                       ----------
          2001..................................................       102.571%

          2002..................................................       101.714

          2003..................................................       100.857


and 100% at May 15,  2004;  provided  that any  semi-annual  payment of interest
becoming due on the date fixed for redemption shall be payable to the holders of
record on the relevant record date of the Notes being redeemed.

           If less than all of the  outstanding  Notes are to be  redeemed,  the
Trustee shall select the Notes to be redeemed in principal  amounts of $1,000 or
multiples  thereof by lot, pro rata or by another  method the Trustee  considers
fair and  appropriate.  If a portion of a holder's Notes is selected for partial
redemption  and such  holder  converts a portion of such Notes,  such  converted
portion shall be deemed to be of the portion selected for redemption.


Redemption at Option of the Holder

           If a Fundamental  Change (as defined  below) occurs at any time prior
to May 15,  2004,  each  holder of Notes shall have the right,  at the  holder's
option,  to require the Company to redeem any or all of such  holder's  Notes on
the date (the "Repurchase Date") that is 30 days after the date of the Company's
notice of such Fundamental  Change. The Notes will be redeemable in multiples of
$1,000 principal amount.

           The  Company  shall  redeem  such  Notes at a price  (expressed  as a
percentage of the principal amount) equal to (i) 106.000% if the Repurchase Date
is before May 15,  1998,  (ii)  105.143%  if the  Repurchase  Date is during the
12-month period beginning May 15, 1998, (iii) 104.286% if the Repurchase Date is
during the period  beginning  May 15,  1999 and ending on May 17,  2000 and (iv)
thereafter at the redemption  price set forth under "Optional  Redemption by the
Company"  which would be applicable to a redemption at the option of the Company
on the Repurchase  Date;  provided that, if the Applicable Price (as defined) is
less than the Reference Market Price (as defined), the Company shall redeem such
Notes at a price  equal to the  foregoing  redemption  price  multiplied  by the
fraction  obtained by dividing  the  Applicable  Price by the  Reference  Market
Price. In each case, the Company shall also pay accrued interest on the redeemed
Notes to, but excluding,  the Repurchase Date; provided that, if such Repurchase
Date is an interest  payment date, then the interest  payable on such date shall
be paid to the holder of record of the Notes on the relevant record date.

           The Company is required to mail to all holders of record of the Notes
a notice of the occurrence of a Fundamental  Change and of the redemption  right
arising as a result  thereof on or before the tenth day after the  occurrence of
such Fundamental  Change.  The Company is also required to deliver the Trustee a
copy of such notice.  To exercise the  redemption  right,
                                      -14-
<PAGE>

a holder of Notes must deliver,  on or before the 30th day after the date of the
Company's notice of a Fundamental  Change (the  "Fundamental  Change  Expiration
Time"), written notice of the holder's exercise of such right, together with the
Notes to be so redeemed, duly endorsed for transfer, to the Company (or an agent
designated by the Company for such purpose).  Payment for Notes  surrendered for
redemption (and not withdrawn) prior to the Fundamental  Change  Expiration Time
will be made promptly following the Repurchase Date.

           The term "Fundamental Change" means the occurrence of any transaction
or event in connection with which all or substantially all Common Stock shall be
exchanged for,  converted into,  acquired for or constitute the right to receive
consideration  which is not all or  substantially  all common  stock listed (or,
upon consummation of or immediately  following such transaction or event,  which
will be listed) on a United States national  securities exchange or approved for
quotation on the NASDAQ  National  Market or any similar United States system of
automated  dissemination of quotations of securities prices (whether by means of
an  exchange   offer,   liquidation,   tender  offer,   consolidation,   merger,
combination,   reclassification,   recapitalization  or  otherwise).   The  term
"Applicable  Price" means (i) in the event of a Fundamental  Change in which the
holders of Common Stock  receive only cash,  the amount of cash  received by the
holder  of one  share  of  Common  Stock  and  (ii) in the  event  of any  other
Fundamental  Change,  the average of the last reported sale price for the Common
Stock during the ten trading days prior to the record date for the determination
of the holders of Common Stock entitled to receive cash, securities, property or
other assets in connection  with such  Fundamental  Change,  or, if there is not
such record date, the date upon which the holders of the Common Stock shall have
the  right to  receive  such  cash,  securities,  property  or other  assets  in
connection with the Fundamental  Change. The term "Reference Market Price" shall
initially mean $13.75 and in the event of any adjustment to the conversion price
described above pursuant to the provisions of the Indenture the Reference Market
Price shall also be adjusted so that the ratio of the Reference  Market Price to
the conversion  price after giving effect to any such adjustment shall always be
the same as the ratio of $13.75 to the conversion  price (without  regard to any
adjustment thereto).

           The Company  will comply  with the  provisions  of Rule 13e-4 and any
other tender offer rules under the Exchange Act which may then be  applicable in
connection  with  the  redemption  rights  of Note  holders  in the  event  of a
Fundamental  Change.  The  redemption  rights  of the  holders  of  Notes  could
discourage  a  potential  acquiror  of  the  Company.   The  Fundamental  Change
redemption feature,  however, is not the result of management's knowledge of any
specific  effort to obtain  control of the Company by means of a merger,  tender
offer,  solicitation  or  otherwise,  or part of a plan by management to adopt a
series of anti-takeover provisions.

           The Company could,  in the future,  enter into certain  transactions,
including certain  recapitalizations of the Company, that would not constitute a
Fundamental  Change,  but that would increase the amount of Senior  Indebtedness
outstanding at such time. Further,  payment of the Fundamental Change redemption
price  on the  Notes  may  be  subordinated  to  the  prior  payment  of  Senior
Indebtedness as described  under  "Subordination  of Notes" below.  There are no
restrictions in the Indenture on the creation of additional Senior  Indebtedness
or other indebtedness. Under certain circumstances, the incurrence of additional
indebtedness  could have an adverse  effect on the Company's  ability to service
its  indebtedness,  including the Notes. If a Fundamental  Change were to occur,
there can be no assurance  that the Company would have  sufficient  funds to pay
the Fundamental  Change  redemption  price for all Notes tendered by the holders
thereof.  A default by the  Company on its  obligations  to pay the  Fundamental
Change  redemption  price could result in  acceleration  of the payment of other
indebtedness of the Company at the time  outstanding  pursuant to  cross-default
provisions.

Subordination of Notes

           The Indebtedness evidenced by the Notes is subordinated to the extent
provided  in  the  Indenture  to  the  prior  payment  in  full  of  all  Senior
Indebtedness  and is pari passu in right of payment  with the  Company's  7 3/4%
Convertible  Subordinated  Debentures due 2001.  The Notes also are  effectively
subordinated to all indebtedness and liabilities of subsidiaries of the Company.
Upon any distribution of assets of the Company upon any dissolution, winding up,
liquidation or reorganization, the payment of the principal of, premium, if any,
and interest on the Notes is to be  subordinated  to the extent  provided in the
Indenture in right of payment to the prior payment in full in cash of all Senior
Indebtedness.  In the event of any acceleration of the Notes because of an Event
of Default (as defined in the Indenture), the holders of any Senior Indebtedness
then outstanding would be entitled to payment in full in cash of all obligations
in  respect of such  Senior  Indebtedness  before  the  holders of the Notes are
entitled  to  receive  any  payment or  distribution  in  respect  thereof.  The
Indenture requires the Company to promptly notify holders of Senior Indebtedness
if payment of the Notes in accelerated because of an Event of Default.

           The Company  also may not make any payment  upon or in respect of the
Notes if (i) a default in the  payment of the  principal  of,  premium,  if any,
interest, rent or other obligations in respect of Senior Indebtedness occurs and
is continuing  beyond any  applicable  period of grace or (ii) any other default
occurs and is continuing  with respect to  Designated  Senior  Indebtedness  (as
defined) that permits holders of the Designated Senior  Indebtedness as to which
such default  relates to  accelerate  its  maturity  and the Trustee  receives a
notice of such default (a "Payment  Blockage  Notice") from the Company or other
person permitted to give such notice under the Indenture.  Payments on the Notes
may and  shall be  resumed  (a) in case of a payment  default,  upon the date on
which such default is cured or waived and (b) in case of a  nonpayment  default,
the earlier of the date on which such  nonpayment  default is cured or waived or
179 days  after  the date on which the  applicable  Payment  Blockage  Notice is
received.  No new  period of  payment  blockage  may be  commenced  to a Payment
Blockage  Notice  unless and until (i) 365 days have  elapsed  since the initial
effectiveness  of the  immediately  prior Payment  Blockage  Notice and (ii) all
scheduled payments of principal, premium, if any, and interest on the Notes that
have come due have  been  paid in full in cash.  During  any  period of  payment
blockage,  any payment  that  otherwise  would have been made during such period
will accrue interest, to the extent legally permissible,  at the annual rate set
forth on the cover page hereof from the date on which such  payment was required
under  the  terms of the  Indenture  until the date of  payment.  No  nonpayment
default  that existed or was  continuing  on the date of delivery of any Payment
Blockage  Notice to the  Trustee  shall  be,  or shall be made,  the basis for a
subsequent Payment Blockage Notice.

           By reason of the  subordination  provisions  described  above, in the
event of the Company's  bankruptcy,  dissolution or  reorganization,  holders of
Senior  Indebtedness  may receive  more,  ratably,  and holders of the Notes may
receive  less,  ratably,   than  the  other  creditors  of  the  Company.   Such
subordination  will not prevent the occurrence of any Event of Default under the
Indenture.

           The term "Senior  Indebtedness"  means the principal of, premium,  if
any, interest (including all interest accruing subsequent to the commencement of
any bankruptcy or similar  proceeding,  whether or not a claim for post-petition
interest is allowable as a claim in any such  proceeding) and rent payable on or
in connection  with, and all fees,  cost,  expenses and other amounts accrued or
due on or in connection  with,  Indebtedness  (as defined below) of the Company,
whether  outstanding  on the  date  of this  Indenture  or  thereafter  created,
incurred,  assumed, guaranteed or in effect guaranteed by the Company (including
all   deferrals,   renewals,   extensions  or  refundings   of,  or  amendments,
modifications  or  supplements  to,  the  foregoing),  unless in the case of any
particular  Indebtedness  the instrument  creating or evidencing the same or the
assumption or guarantee thereof expressly  provides that such Indebtedness shall
not be senior in right of payment to the Notes or expressly  provides  that such
Indebtedness  
                                      -16-
<PAGE>

is pari passu with or junior to the Notes.  Notwithstanding  the foregoing,  the
term  Senior  Indebtedness  does not include  the  Company's 7 3/4%  Convertible
Subordinated  Debentures  due 2001 and any  Indebtedness  of the  Company to any
subsidiary  of the  Company,  a majority of the voting  stock of which is owned,
directly or indirectly, by the Company.

           The term "Indebtedness" means, with respect to any Person (as defined
in the Indenture), and without duplication:


                  (a)  all  indebtedness,   obligations  and  other  liabilities
         (contingent or otherwise) of such Person for borrowed money  (including
         obligations of the Company in respect of overdrafts,  foreign  exchange
         contracts,  currency  exchange  agreements,  interest  rate  protection
         agreements,  and any  loans or  advances  from  banks,  whether  or not
         evidenced  by notes or  similar  instruments)  or  evidenced  by bonds,
         debentures,  notes or similar instruments  (whether or not the recourse
         of the lender is to the whole of the assets of such Person or to only a
         portion  thereof)  (other  than any  account  payable or other  accrued
         current  liability or  obligation  incurred in the  ordinary  course of
         business in connection with the obtaining of materials or service),

                  (b)  all  reimbursement   obligations  and  other  liabilities
         (contingent  or  otherwise)  of such Person with  respect to letters of
         credit, bank guarantees or bankers' acceptances,

                  (c) all obligations and liabilities  (contingent or otherwise)
         in  respect  of leases of such  Person  required,  in  conformity  with
         generally  accepted  accounting  principles,  to be  accounted  for  as
         capitalized  lease  obligations on the balance sheet of such Person and
         all obligations and other  liabilities  (contingent or otherwise) under
         any lease or  related  document  (including  a purchase  agreement)  in
         connection  with the lease of real  property  which  provides that such
         Person in contractually obligated to purchase or cause a third party to
         purchase the leased property and thereby  guarantee a minimum  residual
         value of the leased  property to the lessor and the obligations of such
         Person  under such lease or related  document to purchase or to cause a
         third party to purchase such leased property,

                  (d) all  obligations of such Person  (contingent or otherwise)
         with respect to an interest rate or other swap, cap or collar agreement
         or other  similar  instrument or agreement or foreign  currency  hedge,
         exchange, purchase or similar instrument or agreement,

                  (e) all direct or indirect guaranties or similar agreements by
         such Person in respect of, and  obligations or liabilities  (contingent
         or  otherwise)  or such  Person to  purchase  or  otherwise  acquire or
         otherwise assure a creditor  against loss in respect of,  indebtedness,
         obligations  or  liabilities of another Person of the kind described in
         clauses (a) through (d),

                  (f) any indebtedness or other obligations described in clauses
         (a)  through  (d)  secured  by any  mortgage,  pledge,  lien  or  other
         encumbrance existing on property which is owned or held by such Person,
         regardless  of whether the  indebtedness  or other  obligation  secured
         thereby shall have been assumed by such Person, and

                  (g) any and all deferrals, renewals, extensions and refundings
         of, or amendments,  modifications or supplements to, any  indebtedness,
         obligation  or liability  of the kind  described in clauses (a) through
         (f).

           The term "Designated Senior Indebtedness" means any particular Senior
Indebtedness  in which the  instrument  creating or  evidencing  the same or the
assumption or guarantee thereof (or related agreements or documents to which the
Company is a party) expressly  provides that 
                                      -17-
<PAGE>

such Senior Indebtedness shall be "Designated Senior  Indebtedness" for purposes
of the Indenture (provided that such instrument, agreement or other document may
place  limitations  and conditions on the right of such Senior  Indebtedness  to
exercise the rights of Designated Senior Indebtedness).

           At March 29,  1997,  the  Company  had  approximately  $28 million of
outstanding Senior  Indebtedness  consisting of approximately $23 million of the
Company's 8 3/8% Sinking Fund Debentures due 2002 and  approximately  $5 million
of contingent  reimbursement  obligations under  outstanding  letters of credit.
Subsequent to March 29, 1997, the Company retired the outstanding 8 3/8% Sinking
Fund  Debentures  by using a portion of the proceeds of the sale of the Notes to
the Initial Purchasers.  At March 29, 1997, the Company's subsidiaries had other
indebtedness   and   liabilities  of   approximately   $89  million   (excluding
intercompany obligations). The Indenture will not limit the amount of additional
Indebtedness,  including  Senior  Indebtedness,  which the  Company  can create,
incur,  assume  or  guarantee,  nor will  the  Indenture  limit  the  amount  of
indebtedness or liabilities  which any subsidiary can create,  incur,  assume or
guarantee.

           In the event that,  notwithstanding the foregoing, the Trustee or any
holder  of the Notes  receives  any  payment  or  distribution  of assets of the
Company or any kind in contravention of any of the  subordination  provisions of
the  Indenture,  whether in cash,  property or  securities,  including,  without
limitation,  by way of set-off or otherwise,  in respect of the Notes before all
Senior  Indebtedness is paid in full, then such payment or distribution  will be
held by the recipient in trust for the benefit of holders of Senior Indebtedness
or their  representatives to the extent necessary to make payment in full of all
Senior  Indebtedness  remaining  unpaid,  after giving effect to any  concurrent
payment or distribution,  or provision therefor, to or for the holders of Senior
Indebtedness.

           The  Company  is  obligated  to pay  reasonable  compensation  to the
Trustee and to indemnify the Trustee  against  certain  losses,  liabilities  or
expenses incurred by it in connection with its duties relating to the Notes. The
Trustee's  claims for such payments  generally are senior to those of holders of
the Notes in respect of all funds collected or held by the Trustee.


Events of Default; Notice and Waiver

           An Event of Default is defined in the Indenture as being:  default in
payment of the  principal  of or premium,  if any, on the Notes;  default for 30
days in payment of any  installment  of  interest  on the Notes;  default by the
Company for 60 days after notice in the  observance or  performance of any other
covenants in the Indenture;  or certain events involving bankruptcy,  insolvency
or  reorganization of the Company.  The Indenture  provides that the Trustee may
withhold notice to the holders of the Notes of any default (except in payment of
principal  of,  premium,  if any, or interest  with respect to the Notes) if the
Trustee considers it in the interest of the holders of the Notes to do so.

           The  Indenture  provides  that if an  Event  of  Default  shall  have
occurred and be  continuing,  the Trustee or the holders of not less than 25% in
principal  amount of the Notes then outstanding may declare the principal of and
accrued interest on the Notes to be due and payable immediately.  In the case of
certain events of bankruptcy or insolvency,  the principal of, premium,  if any,
and interest on the Notes shall automatically  become and be immediately due and
payable.  However, if the Company shall cure all defaults (except the nonpayment
of principal of,  premium,  if any, and interest on any of the Notes which shall
have become due by  acceleration)  and certain  other  conditions  are met, with
certain  exceptions,  such  declaration may be canceled and past defaults may be
waived by the  holders of a majority of the  principal  amount of the Notes then
outstanding.
                                      -18-
<PAGE>

           The  holders  of a  majority  in  principal  amount of the Notes then
outstanding  have the right to direct the time,  method and place of  conducting
any  proceedings  for any remedy  available to the  Trustee,  subject to certain
limitations specified in the Indenture.


Modification of the Indenture

           The  Indenture  contains  provisions  permitting  the Company and the
Trustee,  with the  consent  of the  holders  of not  less  than a  majority  in
principal amount of the Notes at the time  outstanding,  to modify the Indenture
or any supplemental  indenture or the rights of the holders of the Notes, except
that no such  modification  shall (i)  extend  the fixed  maturity  of any Note,
reduce the rate or extend the time for payment of interest  thereon,  reduce the
principal amount thereof or premium, if any, thereon,  reduce any amount payable
upon redemption or repurchase  thereof,  change the obligation of the Company to
repurchase  any Note upon the  happening of any  Fundamental  Change in a manner
adverse to holders of Notes,  impair the right of a holder to institute suit for
the payment thereof,  change the currency in which the Notes are payable, impair
the right to convert the Notes into Common Stock  subject to the terms set forth
in the Indenture,  or modify the provisions of the Indenture with respect to the
subordination  of the Notes in a manner  adverse to the  holders of the Notes in
any material respect,  without the consent of each holder of a Note so affected,
or (ii) reduce the  aforesaid  percentage of Notes whose holders are required to
consent to any such supplemental  indenture,  without the consent of the holders
of all of the Notes then  outstanding.  The Indenture  also provides for certain
modifications of its terms without the consent of holders of the Notes.


Registration Rights of the Noteholders

           Pursuant to the Registration Rights Agreement,  the Company has filed
with the Commission the Registration Statement, of which this Prospectus forms a
part,  covering  resales by holders of the Notes and the Common  Stock  issuable
upon  conversion  of the Notes  within 60 days after the latest date of original
issuance of the Notes. The Company has agreed to use reasonable  efforts to keep
the Registration  Statement effective until the earlier of (i) the sale pursuant
to the Registration  Statement of all the securities  registered  thereunder and
(ii) the expiration of the holding period  applicable to such  securities  under
Rule 144(k) under the Securities  Act, or any successor  provision.  The Company
will be  permitted  to suspend  the use of this  Prospectus  for a period not to
exceed 30 days in any  three-month  period,  or not to exceed an aggregate of 60
days in any 12-month  period  under  certain  circumstances  relating to pending
corporate  developments,  public filings with the Commission and similar events.
The Company has agreed to pay predetermined  liquidated damages to those Selling
Securityholders  who  have  requested  to  sell  pursuant  to  the  Registration
Statement  if  the  Registration  Statement  is  not  timely  filed  or if  this
Prospectus is unavailable  for periods in excess of those permitted  above.  The
Company has further agreed, if such failure to file or unavailability  continues
for an additional thirty-day period, to pay predetermined  liquidated damages to
all Selling  Securityholders,  whether or not such holder has  requested to sell
pursuant to the Registration  Statement.  A Selling Securityholder who sells the
Notes or the Shares  pursuant to the  Registration  Statement  generally will be
required to be named as a selling  stockholder  in the  Prospectus,  deliver the
Prospectus to purchasers  and be bound by those  provisions of the  Registration
Rights Agreement (the  "Registration  Rights Agreement") which are applicable to
the Selling Securityholders (including indemnification  provisions). The Company
will pay all  expenses of the  Registration  Statement,  provide to each Selling
Securityholder  copies of this  Prospectus,  notify each Selling  Securityholder
when the  Registration  Statement  has become  effective  and take certain other
actions as are  required  to  permit,  subject  to the  foregoing,  unrestricted
resales of the Notes or the Common Stock.

Information Concerning the Trustee

           The Bank of New York,  as the Trustee under the  Indenture,  has been
appointed  by the  Company as paying  agent,  conversion  agent,  registrar  and
custodian with regard to the Notes.


                          DESCRIPTION OF CAPITAL STOCK

           The  Company  is  authorized  to issue  100,000,000  shares of Common
Stock, $.01 par value, and, 1,000,000 shares of Preferred Stock, $.01 par value.
The following brief description of the capital stock of the Company is qualified
in  its  entirety  by  reference  to  the  Company's  Restated   Certificate  of
Incorporation,  as amended,  copies of which are on file with the Commission and
the New York Stock Exchange.


Description of Common Stock

           The Company had  outstanding  on May 13, 1997,  40,659,397  shares of
Common Stock. All issued and outstanding shares of Data General Common Stock are
fully paid and  nonassessable.  Each  holder of Common  Stock is entitled to one
vote per share.  Subject to the rights of the holders of  outstanding  Preferred
Stock, if any, in the event of any liquidation,  dissolution, or winding up, the
holders  of  Common  Stock  will be  entitled  to share  ratably  in the  assets
available for distribution  after payment of liabilities.  The holders of Common
Stock have equal rights,  share for share, to receive dividends when declared by
the  Board  of  Directors  out of  funds  legally  available  therefor.  No cash
dividends have been paid to  stockholders  of Data General to date. No holder of
Common Stock has any  preemptive  right to subscribe  for any  securities of the
Company. The shares of Common Stock do not have cumulative voting rights.

           The Company's  Restated  Certificate  of  Incorporation  requires the
approval  of at least  two-thirds  of the  outstanding  shares of the  Company's
voting securities held by stockholders other than a holder of 20% or more of the
voting  securities  ("Acquiring  Person")  as a  condition  to  mergers or other
business  combinations  involving  the Company and the  Acquiring  Person unless
certain minimum price form of consideration and procedural  requirements are met
or a majority of the Continuing Directors ("Continuing  Directors" being defined
as a director  who was a member of the Board of  Directors on December 17, 1984,
together  with  each  director  who  was a  member  of the  Board  of  Directors
immediately   prior  to  the  time  that  the  Acquiring  Person  became  a  20%
stockholder,  and any  successor or nominee  nominated or approved by a majority
vote of the then Continuing Directors) approved the transaction.

           The Transfer  Agent and Registrar for the Common Stock is The Bank of
New York.

           The  Common  Stock is listed on the New York Stock  Exchange  and the
London Stock Exchange.

Description of Preferred Stock

           The Board of Directors  has authority to issue  preferred  stock from
time to time without stockholder  approval,  in one or more series. The Board of
Directors  has  created  a series  of  preferred  stock in  connection  with the
Company's  Stockholders'  Rights Plan described below. The Board of Directors is
authorized with respect to any series of preferred stock to fix the designation,
the number of shares,  the  voting  powers,  the  conditions  of the  conversion
privilege,  if any, the terms and conditions of the redemption  rights,  if any,
the rights upon  liquidation,  merger,  consolidation,  distribution  or sale of
assets, dissolution or winding up, the dividend rate and whether dividends shall
be cumulative,  and any other powers,  preferences and relative,  participating,
optional and other rights and the  qualifications,  limitations and 
                                      -20-
<PAGE>

restrictions of such series. These terms could adversely affect the interests of
the holders of the Common  Stock.  The  authority  of the Board of  Directors to
issue preferred stock without further stockholder approval could be exercised in
a manner  that might have the effect of  delaying,  deferring  or  preventing  a
change of control of the Company.

Description of Rights Attached to Common Stock

           Pursuant to the Company's  Stockholders'  Rights Plan,  each share of
the Company's  Common Stock now  outstanding,  or issued prior to the separation
referred to below,  has  attached  to it one Right to  Purchase  Series A Junior
Participating  Preferred  Stock,  par value  $.01 per share,  of the  Company (a
"Right").  No separate  certificates  have been  distributed with respect to the
Rights,  and the  Rights are not now  exercisable.  Ten days  following  certain
events involving the acquisition of, or attempts to acquire,  20% or more of the
Company's Common Stock or a determination that an "adverse person" has purchased
15% or more of the Common Stock, the Rights would separate from the Common Stock
and,  if  not  redeemed  by the  Company,  would  become  exercisable  upon  the
occurrence of certain further  events.  Notes converted prior to such separation
will  receive  one  Right  for each  share of Common  Stock  received  upon such
conversion;  however,  Notes  converted  after such  separation will not receive
Rights. Each full Right, if it became  exercisable,  would entitle the holder to
purchase one hundredth of a share of the Company  Series A Junior  Participating
Preferred Stock for a purchase price of $100. The Rights also entitle holders to
purchase  shares of the Company's or an  acquiror's  common stock at one-half of
market value under circumstances which include certain transactions by or with a
potential  acquiror,  including  "adverse  persons,"  mergers and certain assets
sales. The Rights may be redeemed by the Company under certain  circumstances at
a  redemption  price of $.01.  The Rights will expire on October 19, 2001 unless
previously  redeemed.  The Rights have certain  anti-takeover  effects,  and may
cause  substantial  dilution  to a person or group that  attempts to acquire the
Company on terms not approved by the Board of Directors.

           The rights are governed by the terms of the Rights Agreement dated as
of October 3, 1986,  Renewed and  Restated as of October 19,  1996,  between the
Company and The Bank of New York, as Rights  Agent,  a copy of which is filed as
an exhibit to the form 8-A/A  filed with the  Commission  by the Company on June
27, 1996,  which  exhibit is  incorporated  herein by  reference.  The foregoing
summary  of  the  Stockholders'   Rights  Plan  incorporates  by  reference  the
applicable  sections and paragraphs of the Rights  Agreement and is qualified in
its entirety by such reference.

Description of 8 3/8% Sinking Fund Debentures due 2002

           At March 29,  1997,  the Company had  outstanding  approximately  $23
million  aggregate  principal  amount of its 8 3/8% Sinking Fund  Debentures due
2002.  Subsequent to March 29, 1997, the Company retired the 8 3/8% Sinking Fund
Debentures  using a portion  of the  proceeds  form the sale of the Notes to the
Initial Purchasers.

Description of 7 3/4% Convertible Subordinated Debentures due 2001

           The Company has outstanding  $125,000,000  principal  amount of its 7
3/4%  Convertible  Subordinated  Debentures  due 2001 (the  "1991  Debentures").
Interest on the 1991 Debentures is payable  semi-annually on June 1 and December
1. The 1991  Debentures may be redeemed in whole or in part at the option of the
Company at any time,  at a price,  expressed  as a percentage  of the  principal
amount,  equal to 103.875% as of June 1, 1996 and  declining  to 100% on June 1,
2001, plus accrued  interest  thereon,  and may be redeemed at the option of the
holder if there is a Fundamental Change (as defined in the indenture under which
the  1991  Debentures  were  issued)  in  the  Company's  operations.  The  1991
Debentures are convertible  into Common Stock at the option of the holer, at any
time prior to  redemption  or  repurchase,  at a conversion  price of $19.20 per
share,  subject to  adjustment  for  certain  events.  The 1991  
                                      -21-
<PAGE>

Debentures  are  subordinated  to all  Senior  Indebtedness  (as  defined in the
indenture).  The  indenture  does not contain  any  financial  covenants  or any
restrictions  on the payment of dividends  or the  repurchase  of the  Company's
securities.


                    CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

           The following general  discussion  summarizes certain of the material
United States  federal  income tax  consequences  attribute to the  acquisition,
ownership and disposition of Notes. The summary is based on the Internal Revenue
code of 1986, as amended (the "Code"), Treasury regulations, court decisions and
Internal  Revenue Service  ("Service")  rulings now in effect,  all of which are
subject to change,  possibly with retroactive effect. This summary does not deal
with  all  aspects  of  United  States  federal  income  taxation,  nor with the
particular  United States federal income tax  consequences  that result from the
tax status or particular  circumstances  of holders subject to special tax rule,
such as banks, insurance companies,  regulated investment companies, real estate
investment trusts, brokers and dealers in securities or currencies, persons that
hold Notes as a position  in a  "straddle,"  as part of a "hedge,"  as part of a
"conversion" transaction or as part of any other integrated investment,  persons
that have a functional  currency other than the U.S.  dollar,  personal  holding
companies,  corporations  subject to the  alternative  minimum  tax,  tax-exempt
entities and investors in  pass-through  entities.  This summary deals only with
Notes held as "capital assets" as defined in section 1221 of the Code. Moreover,
this  discussion does not address the effect of any applicable  state,  local or
foreign tax laws.

           The  following  discussion  is limited to the United  States  federal
income tax  consequences  relevant to a holder  that is a "U.S.  Holder." A U.S.
Holder is a holder of Notes who is a citizen or  resident  of the United  States
for federal income tax purposes, or which is a corporation, partnership or other
entity created or organized under the laws of the United States or any political
subdivision  thereof,  an estate the income of which is  includible in its gross
income for United  States  federal  income tax  purposes  without  regard to its
source,  or a trust if (i) a U.S. court is able to exercise primary  supervision
over the administration of the trust and (ii) one or more U.S.  fiduciaries have
the authority to control all the substantial decisions of the trust.

           Prospective  purchasers are advised to consult their own tax advisors
regarding the tax  consequences  of acquiring,  holding or disposing of Notes in
light of their personal investment  circumstances,  and the consequences to them
under state, local and foreign tax laws.

           Stated Interest

           The stated interest on a Note will be taxable to a holder as ordinary
interest income either at the time it accrues or is received depending upon such
holders' method of accounting for federal income tax purposes.

           Redemption or Sale of Notes

           Generally  a holder  will  recognize  taxable  gain or loss  upon the
redemption,  sale or other disposition of Notes equal to the difference  between
(i) the amount of cash and the fair market value of any other property  received
and (ii) such  holder's  tax basis in the Notes.  To the extent  that the amount
received is attributable to accrued but unpaid  interest,  however,  that amount
will be taxed as ordinary  income.  A holder's tax basis in the notes generally
will be the price such holder paid for the Notes, increased by the amount of any
market discount previously taken into income by the holder, and reduced (but not
below  zero) by the amount of any bond  premium  amortized  by the  holder.  See
"Notes  Purchased  At A Market  Discount"  and "Notes  Purchased  At A Premium",
below.  Gain or loss on the  disposition of Notes generally will be capital gain
or loss and generally  will be long-term  capital gain or loss if the Notes have
been held for more than one year at the time of disposition.  Subject to certain
                                      -22-

<PAGE>

limited  exceptions,  capital losses cannot be applied to offset ordinary income
for United States federal income tax purposes.

           Conversion of Notes Into Common Stock

           No gain or loss will be  recognized  upon  conversion  of Notes  into
Common Stock,  except with respect to any cash paid in lieu of fractional shares
of Common Stock. The tax basis of the Common Stock received upon conversion will
be equal to the tax  basis of the  Notes  converted,  less any  portion  thereof
allocable to a fractional  share for which cash is received.  The holding period
of the Common Stock received upon  conversion will include the holding period of
the Notes  converted.  Under the  current  ruling  policy of the  Service,  cash
received in lieu of a  fractional  share of Common  Stock  should  generally  be
treated  as payment in  exchange  for such  fractional  share  rather  than as a
dividend.  Gain or loss  recognized  on the  receipt  of cash  paid in lieu of a
fractional  share  generally  will be  capital  gain or loss and will  equal the
difference  between  the  amount of cash  received  and the  amount of tax basis
allocable to the fraction share.

           Adjustment of Conversion Price

           The  conversion  price of the Notes is  subject to  adjustment  under
certain circumstances.  Section 305 of the Code treats as a distribution taxable
as a dividend (to the extent of the Company's  current or  accumulated  earnings
and profits) certain actual or constructive  distributions of stock with respect
to stock or convertible  securities.  Under Treasury regulations,  an adjustment
may,  under  certain  circumstances,  be  treated  as a  constructive  dividend.
Generally, a holder's tax basis in a Note will be increased by the amount of any
such constructive dividend.  Similarly, a failure to adjust the conversion price
of the  Notes  to  reflect  a stock  dividend  or  similar  event  could in some
circumstances  give rise to  constructive  dividend  income to holders of Common
Stock.

           Dividends on the Common Stock

           Dividends  paid on the Common Stock  generally  will be includible in
the income of a holder as ordinary income to the extent of the Company's current
or accumulated earnings and profits. Subject to certain limitations, a corporate
taxpayer holding Common Stock that receives  dividends thereon generally will be
eligible for a dividends-received deduction equal to 70 percent of the dividends
received.  Under  legislation  proposed as part of the Clinton  administration's
fiscal year 1998 budget proposal,  the 70-percent  dividends-received  deduction
would be reduced to 50 percent for  dividends  paid or accrued more than 30 days
after the date of enactment of the legislation.

           Sale, Exchange or Redemption of Common Stock

           Upon the sale,  exchange or redemption  of shares of Common Stock,  a
holder  generally  will  recognize  capital gain or loss equal to the difference
between  (i) the  amount  of cash  proceeds  and the  fair  market  value of any
property  received on the sale,  exchange or  redemption  and (ii) such holder's
adjusted  basis in the  Common  Stock.  Subject  to the  market  discount  rules
discussed  below,  such capital  gain or loss will be long-term  capital gain or
loss if the holder's  holding  period in the Common Stock was more than one year
at the time of sale, exchange or redemption.

           Notes Purchased at a Market Discount

           Subject to a de minimis  exception,  a holder of a Note acquired at a
market discount  generally will be required to treat as ordinary income any gain
recognized on the  disposition  of the Note to the extent of the accrued  market
discount on the Note at the time of  disposition.  For this purpose,  the market
discount on a Note generally  will be equal to the amount,  if any,
                                      -23-
<PAGE>

by which the stated  redemption price at maturity of the Note immediately  after
its acquisition  exceeds the holder's tax basis in the Note. In general,  market
discount on a Note will be treated as accruing on a ratable  basis over the term
of the Note or, at the election of the holder,  under a constant yield method. A
holder of a Note acquired at a market discount may also be required to defer the
deduction  of a  portion  of  the  interest  on  any  indebtedness  incurred  or
maintained  to  purchase  or carry the note until the Note is  disposed  of in a
taxable transaction.  The foregoing rules will not apply if the holder elects to
include accrued market discount in income currently. If a holder acquires a Note
at a market  discount and receives Common Stock upon conversion of the note, the
amount of accrued  market  discount with respect to the Note through the date of
the conversion should be treated, under regulations to be issued by the Treasury
Department, as ordinary income on the disposition of the Common Stock.

           Notes Purchased at a Premium

           A  holder  that  purchases  a Note for an  amount  in  excess  of its
principal  amount may be  entitled to elect to treat a portion of such excess as
"amortizable bond premium," which will reduce the amount required to be included
in the  holder's  income each year as interest on the Note by the amount of such
premium  allocable to that year based on the Note's yield to maturity.  However,
under proposed Treasury Regulations, the present value of the conversion feature
of the Notes would be subtracted  from the cost of the Note in  determining  the
amount of any  amortizable  bond  premium.  An election to amortize bond premium
would apply to all debt  instruments  held by the holder at the beginning of the
taxable year to which the election applies or thereafter acquired by the holder.

           Backup Withholding

           Under the backup  withholding  provisions of the Code and  applicable
Treasury regulations, a holder of Notes or Common Stock may be subject to backup
withholding at the rate of 31% with respect to dividends or interest paid on, or
the proceeds of a sale,  exchange or redemption of, Notes or Common Stock. These
backup withholding rules will apply if the holder, among other things, (i) fails
to furnish  its  taxpayer  identification  number  ("TIN"),  (ii)  furnishes  an
incorrect TIN,  (iii) fails to properly  report  interest or dividends,  or (iv)
under certain circumstances, fails to provide a certified statement signed under
penalties of perjury that the TIN furnished is the correct  number and that such
holder  is  not  subject  to  backup  withholding.  The  amount  of  any  backup
withholding  from a payment to a holder will be allowed as a credit  against the
holder's  federal  income tax  liability and may entitle such holder to a refund
provided the required information is furnished to the Service.

                                  LEGAL MATTERS

           The  validity  of the  issuance  of the Notes and the Shares  offered

Item 17.  Undertakings.

        (a)     The undersigned registrant hereby undertakes:
                                                                                
                (1) To file,  during  any  period  in which  offers or sales are
                being made,  a  post-effective  amendment  to this  Registration
                Statement:

                (i) To include any  prospectus  required by section  10(a)(3) of
                the Securities Act of 1933;

                (ii) To reflect  in the  prospectus  any facts or events  which,
                individually or together,  represent a fundamental change in the
                information in the Registration  Statement.  Notwithstanding the
                foregoing,  any  increase or  decrease  in volume of  securities
                offered (if the total dollar value of  securities  offered would
                not exceed that which was registered) and any deviation from the
                low or high end of the estimated  maximum  offering range may be
                reflected in the form of  prospectus  filed with the  Commission
                pursuant  to Rule  424(b) if, in the  aggregate,  the changes in
                volume and price represent no more than 20 percent change in the
                maximum  aggregate  offering price set forth in the "Calculation
                of  Registration  Fee"  table  in  the  effective   Registration
                Statement;

                (iii) To include any  material  information  with respect to the
                plan  of   distribution   not   previously   disclosed   in  the
                Registration   Statement   or  any   material   change  to  such
                information in the Registration Statement;

        provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply
        if the  Registration  Statement  is on  Form  S-3 or Form  S-8,  and the
        information  required to be included in a  post-effective  amendment  by
        those   paragraphs  is  contained  in  periodic  reports  filed  by  the
        registrant  pursuant to Section 13 or 15(d) of the  Securities  Exchange
        Act of 1934  that are  incorporated  by  reference  in the  Registration
        Statement.

                (2) That, for the purpose of determining any liability under the
                Securities Act of 1933, each such post-effective amendment shall
                be deemed to be a new  Registration  Statement  relating  to the
                securities offered therein,  and the offering of such securities
                at that  time  shall  be  deemed  to be the  initial  bona  fide
                offering thereof.

                (3) To remove  from  registration  by means of a  post-effective
                amendment any of the securities  being  registered  which remain
                unsold at the termination of the offering.

        (b) The undersigned  registrant  hereby undertakes that, for purposes of
        determining  any liability under the Securities Act of 1933, each filing
        of the  registrant's  annual 
                                      II-2
<PAGE>

        report  pursuant  to Section  13(a) or Section  15(d) of the  Securities
        Exchange Act of 1934 (and, where applicable,  each filing of an employee
        benefit plan's annual report pursuant to Section 15(d) of the Securities
        Exchange  Act  of  1934)  that  is  incorporated  by  reference  in  the
        Registration  Statement  shall  be  deemed  to  be  a  new  Registration
        Statement relating to the securities  offered therein,  and the offering
        of such  securities  at that time shall be deemed to be the initial bona
        fide offering thereof.

        (c)  Insofar  as  indemnification  for  liabilities  arising  under  the
        Securities  Act of 1933 may be  permitted  to  directors,  officers  and
        controlling   persons  of  the  registrant  pursuant  to  the  foregoing
        provisions,  or otherwise,  the  registrant has been advised that in the
        opinion of the Securities and Exchange  Commission such  indemnification
        is against  public policy as expressed in the Securities Act of 1933 and
        is, therefore,  unenforceable.  In the event a claim for indemnification
        against such  liabilities  (other than the payment by the  registrant of
        expenses incurred or paid by a director,  officer, or controlling person
        of the  registrant  in the  successful  defense of any  action,  suit or
        proceeding) is asserted by such director, officer, or controlling person
        of the registrant in connection  with the securities  being  registered,
        the registrant will, unless in the opinion of its counsel the matter has
        been settled by controlling precedent,  submit to a court of appropriate
        jurisdiction the question whether such  indemnification by it is against
        public  policy as  expressed in the  Securities  Act of 1933 and will be
        governed by the final adjudication of such issue.

                      (a)   The Company shall cause to be kept at the Corporate
Trust Office a register (the register maintained in such office and in any other
office or agency of the Company designated  pursuant to Section 5.2 being herein
sometimes  collectively referred to as the "Note register") in which, subject to
such reasonable  regulations as it may prescribe,  the Company shall provide for
the  registration of Notes and of transfers of Notes. The Note register shall be
in written  form or in any form  capable of being  converted  into  written form
within a reasonably prompt period of time. The Trustee is hereby appointed "Note
registrar" for the purpose of registering Notes and transfers of Notes as herein
provided.  The Company may appoint one or more  co-registrars in accordance with
Section 5.2.

         Upon  surrender  for  registration  of transfer of any Note to the Note
registrar or any  co-registrar,  and  satisfaction of the  requirements for such
transfer set further in this Section 2.5,  the Company  shall  execute,  and the
Trustee shall  authenticate and make available for delivery,  in the name of the
designated  transferee or  transferees,  one or more new Notes of any authorized
denominations  and  of a  like  aggregate  principal  amount  and  bearing  such
restrictive legends as may be required by this Indenture.

         Notes may be exchanged for other Notes of any authorized  denominations
and of a like  aggregate  principal  amount,  upon  surrender of the Notes to be
exchanged  at any such office of agency  maintained  by the Company  pursuant to
Section 5.2.  Whenever any Notes are so  surrendered  for exchange,  the Company
shall  execute,  and the  trustee  shall  authenticate  and make  available  for
delivery,  the Notes  which the  Noteholder  making the  exchange is entitled to
receive bearing registration numbers not contemporaneously outstanding.

                                      -12-
<PAGE>

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

         All Notes presented or surrendered for  registration of transfer or for
exchange,  redemption or conversion  shall (if so required by the Company or the
Note registrar) be duly endorsed,  or be accompanied by a written  instrument or
instruments of transfer in form satisfactory to the Company, and the Notes shall
be duly executed by the  Noteholder  thereof or his attorney duly  authorized in
writing.

         No service  charge  shall be made for any  registration  of transfer or
exchange of Notes,  but the Company may require  payment of a sum  sufficient to
cover any tax,  assessment or other  governmental  charge that may be imposed in
connection with any registration of transfer or exchange of Notes.

         Neither  the Company  nor the  Trustee  nor any Note  registrar  or any
Company  registrar  shall be  required to exchange or register a transfer of (a)
any Notes for a period of fifteen  (15) days next  preceding  any  selection  of
Notes to be redeemed or (b) any Notes or portions  thereof called for redemption
pursuant  to Article  III or (c) any Notes or portion  thereof  surrendered  for
conversion pursuant to Article XV.

                        (b)   So long as the Notes are eligible  for  book-entry
settlement with the Depositary,  or unless otherwise  required by law, all Notes
that are so  eligible  may be  represented  by one or more Notes in global  form
registered  in the name of the  Depositary  or the  nominee  of the  Depositary,
except as otherwise  specified  below.  The transfer and exchange of  beneficial
interests  in any such  Note in  global  form  shall  be  effected  through  the
Depositary  in  accordance  with  this  Indenture  and  the  procedures  of  the
Depositary therefor.

         Notes that upon initial issuance are beneficially owned by QIBs will be
represented  by a global  Note (the  "144A  Global  Note"),  and Notes that upon
initial issuance are beneficially owned by Non-U.S.  Persons will be represented
by another global Note (the "Regulation S Global Note").  Transfers of interests
in the Notes between the 144A Global Note and the  Regulation S Global Note will
be made in  accordance  with the standing  instructions  and  procedures  of the
Depositary and its participants. The Trustee shall make appropriate endorsements
to reflect  increases or decreases in the principal amounts of such global Notes
as set forth on the face of the Note  ("Principal  Amount")  to reflect any such
transfers.

         Except as provided  below,  beneficial  owners of a Note in global form
shall not be entitled to have  certificates  registered in their names, will not
receive  or  be  entitled  to  receive  physical  delivery  of  certificates  in
definitive form and will not be considered Holders of such Notes in global form.

                       (c)    So long as the Notes are eligible  for  book-entry
settlement,  or  unless  otherwise  required  by law,  upon  any  transfer  of a
definitive  Note to a QIB in accordance  with Rule 144A, and upon receipt of the
definitive  Note or Notes being so  transferred,  together with a  certification
from the transferor that the transfer is being made in compliance with Rule 144A
(or other  evidence  satisfactory  to the  Trustee),  the Trustee  shall make an
endorsement  on the 144A Global  Note to reflect an  increase  in the  aggregate
Principal  Amount of the Notes  represented  by such  Note in global  form,  the
Trustee  shall  cancel  such  definitive  Note or Notes in  accordance  with the
standing instructions and procedures of the Depositary,  the aggregate Principal
Amount  of  Notes  represented  by such  Note  in  global  form to be  increased
accordingly;  provided,  that no definitive Note, or portion thereof, in respect
of which the Company or an Affiliate of the Company held any beneficial interest
shall be  included  in such Note in global  form until such  definitive  Note is
freely  tradable in  accordance  with Rule  144(k);  provided  further  that the
Trustee shall issue Notes in  definitive  form upon any transfer of a beneficial
interest  in the Note in global  form to the  Company  or any  Affiliate  of the
Company.

         Any Note in global form may be endorsed  with or have  incorporated  in
the text thereof such legends or recitals or changes not  inconsistent  with the
provisions of this Indenture as may be required by the Custodian, the Depositary
or by the National  Association  of  Securities  Dealers,  Inc. in order for the
Notes to be tradeable  on the PORTAL  Market or as may be required for the Notes
to be tradeable on any other market developed for trading of securities pursuant
to Rule 144A or  Regulation S or required to comply with any  applicable  law or
any  regulation  thereunder or with the rules and  regulations of any securities
exchange  or  automated  quotation  system upon which the Notes may be listed or
traded or to conform with any usage with respect  thereto,  or to indicated  any
special limitations or restrictions to which any particular Notes are subject.

                       (d)    Every  Note that bears or is  required  under this
Section  2.5(d) to bear the legend set forth in this  Section  2.5(d)  (together
with any Common Stock issued upon  conversion  of the Notes and required to bear
the  legend  set  forth  in  Section  2.5(e),   collectively,   the  "Restricted
Securities")  shall be subject to the restrictions on transfer set forth in this
Section 2.5(d)  (including those set forth in the legend set forth below) unless
such  restrictions on transfer shall be waived by written consent of the Company
and the holder of each such  Restricted  Note, by such  Noteholder's  acceptance
thereof,  agrees to be bound by all such  restrictions  on transfer.  As used in
Sections 2.5(d) and 2.5(e),  the term "transfer"  encompasses any sale,  pledge,
transfer or other disposition whatsoever of any Restricted Security.

         Until the expiration of the holding period  applicable to sales thereof
under Rule 144(k) under the  Securities  Act (or any successor  provision),  any
certificate evidencing such Note (and all securities issued in exchange therefor
or substitution thereof, other than Common Stock, if any, issued upon conversion
thereof,   which  shall  bear  the  legend  set  forth  in  Section  2.5(e),  if
applicable),  shall bear a legend in  substantially  the following form,  unless
such Note

                                      -14-

has been  sold  pursuant  to a  registration  statement  that has been  declared
effective  under the Securities Act (and which  continues to be effective at the
time of such transfer),  or unless  otherwise  agreed by the Company in writing,
with written notice thereof to the Trustee:

                  INFORMATION AS THE TRUSTEE MAY  REASONABLY  REQUIRE TO CONFIRM
                  THAT SUCH  TRANSFER  IS BEING MADE  PURSUANT  TO AN  EXEMPTION

                  TRANSFERRED  A  NOTICE  SUBSTANTIALLY  TO THE  EFFECT  OF THIS
                  LEGEND.  IN CONNECTION WITH ANY TRANSFER OF THE NOTE EVIDENCED
                  HEREBY  PRIOR  TO  THE   EXPIRATION  OF  THE  HOLDING   PERIOD
                  APPLICABLE  TO SALES OF THE NOTE  EVIDENCED  HEREBY UNDER RULE

                  SUCH TRANSFER, FURNISH TO THE BANK OF NEW YORK, AS TRUSTEE (OR
                  A SUCCESSOR  TRUSTEE,  AS  APPLICABLE),  SUCH  CERTIFICATIONS,
                  LEGAL  OPINIONS  OR  OTHER  INFORMATION  AS IT MAY  REASONABLY
                  REQUIRE TO CONFIRM THAT SUCH  TRANSFER IS BEING MADE  PURSUANT
                  TO AN EXEMPTION  FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
                  REGISTRATION  REQUIREMENTS  OF THE SECURITIES ACT. THIS LEGEND

         therefor) as to which such  restrictions on transfer shall have expired
         in accordance  with their terms or as to the  conditions for removal of
         the foregoing  legend set forth therein have been  satisfied  may, upon
         surrender of such Note for exchange to the Note registrar in accordance
         with the provisions of this Section 2.5, be exchanged for a new Note or
         Notes, of like tenor and aggregate  principal  amount,  which shall not
         bear the restrictive legend required by this Section 2.5(d).

                  Notwithstanding  any other provisions of this Indenture (other
         than the provisions set forth in the second paragraph of Section 2.5(b)
         and in  this  Section  2.5(d)),  a  Note  in  global  form  may  not be
         transferred as a whole or in part except by the Depositary to a nominee
         of the  Depositary or by a nominee of the  Depositary to the Depositary
         or another  nominee of the  Depositary or by the Depositary or any such
         nominee  to a  successor  Depositary  or a  nominee  of such  successor
         Depositary.

                  The Depositary shall be a clearing agency registered under the
         Exchange Act. The Company  initially  appoints DTC to act as Depositary
         with  respect to the Notes in global form.  Initially,  the 144A Global
         Note shall be issued to the Depositary,  registered in the name of Cede
         & Co.,  as the  nominee  of the  Depositary,  and  deposited  with  the
         Custodian for Cede & Co.  Initially,  the  Regulation S Global Note, if
         any, shall be issued to the Depositary,  registered in the name of Cede
         & Co.,  as  nominee  for the  Depositary,  for the  accounts  of Morgan
         Guaranty Trust Company of New York, Brussels office, as operator of the
         Euroclear System and Cedel,  S.A., and deposited with the Custodian for
         Cede & Co.

                  If at any  time  the  Depositary  for a Note  in  global  form
         notifies  the  Company  that it is  unwilling  or unable to continue as
         Depositary   for  such  Note,  the  Company  may  appoint  a  successor
         Depositary with respect to such Note. If a successor  Depositary is not
         appointed  by the  Company  within  ninety  (90) days after the Company
         receives such notice, the Company will execute,  and the Trustee,  upon
         receipt of an Officers' Certificate for the authentication and delivery
         of Notes, will  authenticate and make available for delivery,  Notes in
         certificated form, in aggregate principal amount equal to the principal
         amount of such Note in global form, in exchange for such Note in global
         form.

                  If a Note in  certificated  form is issued in exchange for any
         portion  of a Note in global  form after the close of  business  at the
         office or agency  where such  exchange  occurs on any  record  date and
         before the  opening of  business  at such  office or agency on the next
         succeeding  interest payment date, interest will not be payable on such
         interest  payment date in respect of such Note,  but will be payable on
         such interest  payment date,  subject to the provisions of Section 2.3,
         only to the person to whom  interest in respect of such portion of such
         Note in global form is payable in  accordance  with the  provisions  of
         this Indenture.

                  Notes in  certificated  form issued in  exchange  for all or a
         part of a Note in global  form  pursuant  to this  Section 2.5 shall be
         registered in such names and in such  authorized  denominations  as the
         Depositary,  pursuant  to  instructions  from its  direct  or  indirect
         participants or otherwise,  shall instruct the Trustee.  Upon execution
         and authentication,  the Trustee shall make available for delivery such
         Notes in certificated  form to the persons in whose names such Notes in
         certificated form are so registered.

                  At such time as all  interests  in a Note in global  form have
         been redeemed, converted, canceled, exchanged for Notes in certificated
         form, or transferred to a transferee who receives Notes in certificated
         form thereof,  such Note in global form shall, upon receipt thereof, be
         canceled by the Trustee in  accordance  with  standing  procedures  and
         instructions existing between the Depositary and the Custodian.  At any
         time prior to such  cancellation,  if any  interest in a global Note is
         exchanged  for  Notes  in  certificated  form,   redeemed,   converted,
         repurchased  or  cancelled,  exchanged  for Notes in certified  form or
         transferred  to a transferee who receives  Notes in  certificated  form
         therefor or any Note in  certificated  form is exchanged or transferred
         for part of a Note in global form, the principal amount of such Note in
         global form shall,  in  accordance  with the  standing  procedures  and
         instructions  existing  between the Depositary  and the  Custodian,  be
         appropriately  reduced  or  increased,  as  the  case  may  be,  and an
         endorsement  shall be made on such Note in global form,  by the Trustee
         or the  Custodian,  at the  direction of the  Trustee,  to reflect such
         reduction or increase.

                       (e)      Until  the  expiration  of  the  holding  period
applicable to sales thereof under Rule 144(k) under the  Securities  Act (or any
successor  provision),  any stock certificate  representing  Common Stock issued
upon conversion of such Note shall bear a legend in substantially  the following
form,  unless  such  Common  Stock  has been  sold  pursuant  to a  registration
statement that has been declared  effective  under the Securities Act (and which
continues to be effective at the time of such transfer) or such Common Stock has
been issued upon  conversion of Notes that have been  transferred  pursuant to a
registration  statement  that has been declared  effective  under the Securities
Act, or unless  otherwise  agreed by the Company in writing with written  notice
thereof to the transfer agent:

                  THE COMMON  STOCK  EVIDENCED  HEREBY  HAS NOT BEEN  REGISTERED
                  UNDER  THE  U.S.  SECURITIES  ACT OF  1933,  AS  AMENDED  (THE

                  ACCORDINGLY,  MAY NOT BE  OFFERED  OR SOLD  WITHIN  THE UNITED
                  STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT  OF, U.S.  PERSONS
                  EXCEPT  AS SET FORTH IN THE  FOLLOWING  SENTENCE.  THE  HOLDER
                  HEREOF AGREES THAT UNTIL THE  EXPIRATION OF THE HOLDING PERIOD
                  APPLICABLE  TO SALES OF THE  SECURITY  EVIDENCED  HEREBY UNDER
                  RULE  144(K)  UNDER  THE  SECURITIES  ACT  (OR  ANY  SUCCESSOR

                  PURSUANT TO CLAUSE 1(F) ABOVE) A NOTICE  SUBSTANTIALLY  TO THE
                  EFFECT OF THIS  LEGEND.  THIS LEGEND WILL BE REMOVED  UPON THE
                  EARLIER OF THE TRANSFER OF THE COMMON STOCK  EVIDENCED  HEREBY
                  PURSUANT  TO CLAUSE  1(F)  ABOVE OR UPON ANY  TRANSFER  OF THE
                  COMMON  STOCK  EVIDENCED  HEREBY AFTER THE  EXPIRATION  OF THE
                  HOLDING PERIOD  APPLICABLE TO SALES OF THE SECURITY  EVIDENCED
                  HEREBY  UNDER RULE  144(K)  UNDER THE  SECURITIES  ACT (OR ANY
                  SUCCESSOR  PROVISION).  AS  USED  HEREIN,  THE  TERMS  "UNITED
                  STATES" AND "U.S.  PERSON" HAVE THE MEANINGS  GIVEN TO THEM BY
                  REGULATION S UNDER THE SECURITIES ACT.

                  Any  such  Common  Stock  as to  which  such  restrictions  on
         transfer  shall have  expired in  accordance  with their terms or as to
         which the  conditions  for  removal of the  foregoing  legend set forth
         therein have been  satisfied  may, upon  surrender of the  certificates
         representing  such shares of Common  Stock for  exchange in  accordance
         with the  procedures  of the transfer  agent for the Common  Stock,  be
         exchanged for a new

                                      -19-
<PAGE>

         certificate  or  certificates  for a like  number  of  shares of Common
         Stock,  which shall not bear the  restrictive  legend  required by this
         Section 2.5(e).

                         (f)    Any  Note  or  Common   Stock  issued  upon  the
conversion  or exchange of a Note that,  prior to the  expiration of the holding
period  applicable to sales thereof under Rule 144(k) under the  Securities  Act
(or any  successor  provision),  is  purchased  or owned by the  Company  or any
Affiliate  thereof  may not be resold by the  Company or such  Affiliate  unless
registered  under the Securities Act or resold pursuant to an exemption from the
registration  requirements of the Securities Act in a transaction  which results
in such Notes or Common Stock,  as the case may be, no longer being  "restricted
securities" (as defined under Rule 144).

         Section 2.6. Mutilated,  Destroyed,  Lost or Stolen Notes . In case any
Note shall become mutilated or be destroyed,  lost or stolen, the Company in its
discretion  may execute,  and upon its request the Trustee or an  authenticating
agent  appointed  by the  Trustee  shall  authenticate  and make  available  for
delivery,  a new Note, bearing a number not  contemporaneously  outstanding,  in
exchange  and  substitution  for  the  mutilated  Note,  or in  lieu  of  and in
substitution  for the Note so  destroyed,  lost or  stolen.  In  every  case the
applicant  for a substituted  Note shall furnish to the Company,  to the Trustee
and, if applicable,  to such authenticating  agent such security or indemnity as
may be required by them to save each of them  harmless for any loss,  liability,
cost or expense  caused by or connected  with such  substitution,  and, in every
case of  destruction,  loss or theft,  the  applicant  shall also furnish to the
Company,  to the  Trustee  and,  if  applicable,  to such  authenticating  agent
evidence to their  satisfaction of the  destruction,  loss or theft of such Note
and of the ownership thereof.

         The  Trustee or such  authenticating  agent may  authenticate  any such
substituted  Note and  deliver  the same upon the  receipt of such  security  or
indemnity as the Trustee,  the Company and, if applicable,  such  authenticating
agent may require.  Upon the issuance of any  substituted  Note, 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  connected
therewith.  In case any Note which has matured or is about to mature or has been
called for redemption or is about to be converted into Common Stock shall become
mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a
substitute  Note,  pay or authorize  the payment of or convert or authorize  the
conversion  of the  same  (without  surrender  thereof  except  in the case of a
mutilated  Note),  as the case may be,  if the  applicant  for such  payment  or
conversion shall furnish to the Company,  to the Trustee and, if applicable,  to
such authenticating  agent such security or indemnity as may be required by them
to save each of them harmless for any loss, liability, cost or expense caused by
or connected with such substitution, and, in case of destruction, loss or theft,
evidence satisfactory to the Company, the Trustee and, if applicable, any paying
agent or conversion agent of the destruction,  loss or theft or such Note and of
the ownership thereof.

         Every  substituted  Note  issued  pursuant  to the  provisions  of this
Section  2.6 by virtue of the fact  that any Note is  destroyed,  lost or stolen
shall constitute an additional contractual

                                      -20-
<PAGE>

obligation  of the Company,  whether or not the  destroyed,  lost or stolen Note
shall be found at any time,  and shall be entitled  to all the  benefits of (but
shall be subject to all the limitations set forth in) this Indenture equally and
proportionately  with any and all other  Notes  duly  issued  hereunder.  To the
extent  permitted  by law,  all Notes  shall be held and owned upon the  express
condition  that the  foregoing  provisions  are  exclusive  with  respect to the
replacement  or payment or conversion of  mutilated,  destroyed,  lost or stolen
Notes and shall  preclude any and all other  rights or remedies  notwithstanding
any law or statute existing or hereafter enacted to the contrary with respect to
the  replacement  or payment or conversion of  negotiable  instruments  or other
securities without their surrender.

         Section  2.7.  Temporary  Notes . Pending the  preparation  of Notes in
certificated forms, the Company may execute and the Trustee or an authenticating
agent  appointed by the Trustee shall,  upon the written request of the Company,
authenticate  and make  available  for  delivery  temporary  Notes  (printed  or
lithographed). Temporary Notes shall be issuable in any authorized denomination,
and  substantially in the form of the Notes in certificated  form, but with such
omissions,  insertions and variations as may be appropriate for temporary Notes,
all as may be  determined  by the Company.  Every such  temporary  Note shall be
executed by the Company and authenticated by the Trustee or such  authenticating
agent upon the same conditions and in  substantially  the same manner,  and with
the same effect, as the Notes in certificated form.  Without  unreasonable delay
the Company will execute and deliver to the Trustee or such authenticating agent
Notes in certificated  form (other than in the case of Notes in global form) and
thereupon any or all  temporary  Notes (other than any such Note in global form)
may be surrendered in exchange therefor,  at each office or agency maintained by
the Company pursuant to Section 5.2 and the Trustee or such authenticating agent
shall  authenticate  and deliver in exchange for such  temporary  Notes an equal
aggregate principal amount of Notes in certificated form. Such exchange shall be
made by the Company at its own expense and without any charge therefor. Until so
exchanged,  the  temporary  Notes shall in all  respects be entitled to the same
benefits and subject to the same  limitations  under this  Indenture as Notes in
certificated form authenticated and made available for delivery hereunder.

         Section 2.8. Cancellation of Notes Paid, Etc. All Notes surrendered for
the purpose of payment,  redemption,  conversion,  exchange or  registration  of
transfer,  shall,  if surrendered to the Company or any paying agent or any Note
registrar or any  conversion  agent,  be surrendered to the Trustee and promptly
canceled by it, or, if surrendered to the Trustee, shall be promptly canceled by
it, and no Notes shall be issued in lieu thereof  except as expressly  permitted
by any of the provisions of this Indenture. After such cancellation, the Trustee
shall, if requested by the Company, deliver such cancelled Notes to the Company.
If the  Company  shall  acquire  any of the Notes,  such  acquisition  shall not
operate as a redemption or satisfaction of the indebtedness  represented by such
Notes unless and until the same are delivered to the Trustee for cancellation.

         Section 2.9.  CUSIP  Numbers.  The Company in issuing the Notes may use
"CUSIP"  numbers (if then  generally in use),  and, if so, the Trustee shall use
CUSIP numbers in notices of redemption  as a convenience  to Holders;  provided,
that  any  such  notice  may  state  that  no  representation  is made as to the
correctness  of such  numbers  either as printed on the Notes or as contained in
any notice of a  redemption  and that  reliance  may be placed only on the other
identification  numbers printed on the Notes,  and any such redemption shall not
be  affected  by any defect in or omission  of such  numbers.  The Company  will
promptly notify the Trustee of any change in the CUSIP numbers.

                                   ARTICLE  III

                               REDEMPTION OF NOTES

         Section 3.1.  Redemption  Prices . The Company may not redeem the Notes
prior to May 18, 2000. At any time on or after May 18, 2000, the Company may, at
its  option,  redeem  all or from time to time any part of the Notes on any date
prior to maturity,  upon notice as set forth in Section 3.2, and at the optional
redemption  prices set forth in the form of Note  attached  as Exhibit A hereto,
together with accrued interest to, but excluding, the date fixed for redemption.

         Section  3.2.  Notice of  Redemption;  Selection of Notes . In case the
Company shall desire to exercise the right to redeem all or, as the case may be,
any  part of the  Notes  pursuant  to  Section  3.1,  it  shall  fix a date  for
redemption  and it or, at its  request,  the  Trustee  in the name of and at the
expense  of the  Company,  shall  mail or  cause to be  mailed a notice  of such
redemption  at least thirty (30) days prior to the date fixed for  redemption to
the  holders  of Notes  so to be  redeemed  as a whole or in part at their  last
addresses as the same appear on the Note register (provided, that if the Company
shall give such notice, it shall also give written notice, and written notice of
the Notes to be redeemed  (including  CUSIP  numbers,  if any), to the Trustee).
Such  mailing  shall be by first class mail.  The notice if mailed in the manner
herein provided shall be conclusively  presumed to have been duly given, whether
or not the holder receives such notice. In any case, failure to give such notice
by mail or any  defect in the notice to the  holder of any Note  designated  for
redemption  as a  whole  or in  part  shall  not  affect  the  validity  of  the
proceedings for the redemption of any other Note.

         Each such notice of redemption  shall  specify the aggregate  principal
amount of Notes to be redeemed,  the date fixed for  redemption,  the redemption
price at which Notes are to be  redeemed,  the place or places of payment,  that
payment  will be made  upon  presentation  and  surrender  of such  Notes,  that
interest  accrued to the date fixed for redemption  will be paid as specified in
said notice,  and that on and after said date interest thereon or on the portion
thereof to be redeemed  will cease to accrue.  Such notice  shall also state the
current  Conversion  Price and the date on which the right to convert such Notes
or portions  thereof into Common Stock will expire.  If fewer than all the Notes
are to be  redeemed,  the notice of  redemption  shall  identify the Notes to be
redeemed  (including CUSIP numbers,  if any). In

                                      -22-
<PAGE>

case any Note is to be redeemed  in part only,  the notice of  redemption  shall
state the portion of the principal amount thereof to be redeemed and shall state
that on and after the date fixed for redemption,  upon surrender of such Note, a
new Note or Notes in principal  amount equal to the unredeemed  portion  thereof
will be issued.

         On or  prior  to  the  redemption  date  specified  in  the  notice  of
redemption  given as provided in this Section 3.2, the Company will deposit with
the Trustee or with one or more  paying  agents (or, if the Company is acting as
its own paying  agent,  set aside,  segregate  and hold in trust as  provided in
Section 5.4) an amount of money  sufficient to redeem on the redemption date all
the Notes (or  portions  thereof)  so called for  redemption  (other  than those
theretofore  surrendered  for conversion  into Common Stock) at the  appropriate
redemption  price,  together with accrued  interest to, but excluding,  the date
fixed for redemption;  provided,  that if such payment is made on the redemption
date it must be received by the Trustee or paying agent,  as the case may be, by
10:00 a.m. New York City time, on such date.  If any Note called for  redemption
is converted pursuant hereto, any money deposited with the Trustee or any paying
agent or so segregated  and held in trust for the  redemption of such Note shall
be paid to the Company upon its written request, or, if then held by the Company
shall be  discharged  from  such  trust.  If fewer  than all the Notes are to be
redeemed,  the Company  will give the Trustee  written  notice in the form of an
Officers'  Certificate  not fewer  than  forty-five  (45) days (or such  shorter
period of time as may be acceptable to the Trustee) prior to the redemption date
as to the aggregate principal amount of Notes to be redeemed.

         If fewer  than all the  Notes are to be  redeemed,  the  Trustee  shall
select the Notes or portions  thereof to be redeemed  (in  principal  amounts of
$1,000 or integral multiples  thereof),  by lot or, in its discretion,  on a pro
rata basis.  If any Note  selected for partial  redemption  is converted in part
after such selection, the converted portion of such Note shall be deemed (so far
as may be) to be the  portion  to be  selected  for  redemption.  The  Notes (or
portions  thereof) so selected  shall be deemed duly selected for redemption for
all purposes hereof,  notwithstanding that any such Note is converted as a whole
or in part before the mailing of the notice of redemption.

         Upon any redemption of less than all Notes, the Company and the Trustee
may (but need not) treat as  outstanding  any Notes  surrendered  for conversion
during the period of fifteen (15) days next preceding the mailing of a notice of
redemption  and may (but need not) treat as outstanding  any Note  authenticated
and delivered during such period in exchange for the unconverted  portion of any
Note converted in part during such period.

         Section  3.3.  Payment of Notes  Called for  Redemption  . If notice of
redemption has been given as above provided,  the Notes or portion of Notes with
respect to which such notice has been given shall,  unless converted into Common
Stock pursuant to the terms hereof, become due and payable on the date fixed for
redemption  and at the place or places  stated in such notice at the  applicable
redemption  price,  together with interest  accrued to (but

                                      -23-
<PAGE>

excluding) the date fixed for redemption, and on and after said date (unless the
Company  shall  default in the  payment of such Notes at the  redemption  price,
together with interest accrued to said date) interest on the Notes or portion of
Notes so called for redemption  shall cease to accrue and such Notes shall cease
after the close of business on the  Business Day next  preceding  the date fixed
for  redemption to be convertible  into Common Stock and,  except as provided in
Sections  8.5 and 13.4,  to be entitled  to any  benefit or security  under this
Indenture,  and the holders thereof shall have no right in respect of such Notes
except the right to receive the redemption  price thereof and unpaid interest to
(but excluding) the date fixed for redemption.  On presentation and surrender of
such Notes at a place of payment in said notice specified, the said Notes or the
specified  portions  thereof  shall be paid and  redeemed  by the Company at the
applicable  redemption  price,  together with interest  accrued  thereon to (but
excluding)  the date fixed for  redemption;  provided,  that, if the  applicable
redemption date is an interest payment date, the semi-annual payment of interest
becoming  due on such  date  shall  be  payable  to the  holders  of such  Notes
registered  as  such  on  the  relevant  record  date  instead  of  the  holders
surrendering such Notes for redemption on such date.

         Upon  presentation of any Note 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 Note or Notes, of authorized denominations, in
principal amount equal to the unredeemed portion of the Notes so presented.

         Notwithstanding  the foregoing,  the Trustee shall not redeem any Notes
or mail any notice of optional redemption during the continuance of a default in
payment of interest or premium on the Notes or of any Event of Default of which,
in the case of any Event of Default other than under Sections  7.1(a) or 7.1(b),
a  Responsible  Officer of the  Trustee  has  knowledge.  If any Note called for
redemption  shall not be so paid upon  surrender  thereof  for  redemption,  the
principal  and premium,  if any,  shall,  until paid or duly  provided for, bear
interest  from the date fixed for  redemption  at the rate borne by the Note and
such Note shall remain  convertible  into Common Stock until the  principal  and
premium, if any, shall have been paid or duly provided for.

         Section 3.4.  Conversion  Arrangement on Call for Redemption . In
connection  with any  redemption  of Notes,  the  Company  may  arrange  for the
purchase and conversion of any Notes by an agreement with one or more investment
bankers or other  purchasers  to purchase such Notes by paying to the Trustee in
trust for the Noteholders, on or before the date fixed for redemption, an amount
not less than the applicable redemption price, together with interest accrued to
(but  excluding) the date fixed for redemption,  of such Notes.  Notwithstanding
anything to the contrary  contained in this Article III, the  obligation  of the
Company  to pay the  redemption  price of such  Notes,  together  with  interest
accrued to (but excluding) the date fixed for redemption,  shall be deemed to be
satisfied  and  discharged  to  the  extent  such  amount  is so  paid  by  such
purchasers. If such an agreement is entered into, any Notes not duly surrendered
for  conversion  by the holders  thereof may, at the option of the  Company,  be
deemed, to the fullest extent permitted by law, acquired by such purchasers from
such holders and

                                      -24-
<PAGE>

(notwithstanding  anything to the contrary  contained in Article XV) surrendered
by such purchasers for conversion,  all as of immediately  prior to the close of
business  on the date fixed for  redemption  (and the right to convert  any such
Notes shall be  extended  through  such  time),  subject to payment of the above
amount as aforesaid. A copy of any such agreement will be filed with the Trustee
prior to the date fixed for  redemption.  At the  direction of the Company,  the
Trustee  shall hold and dispose of any such amount paid to it in the same manner
as it would monies deposited with it by the Company for the redemption of Notes.
Without the Trustee's prior written consent,  no arrangement between the Company
and such  purchasers for the purchase and conversion of any Notes shall increase
or otherwise affect any of the powers,  duties,  responsibilities or obligations
of the  Trustee  as set  forth in this  Indenture,  and the  Company  agrees  to
indemnify the Trustee from, and hold it harmless against, any loss, liability or
expense  arising  out of or in  connection  with  any such  arrangement  for the
purchase and conversion of any Notes between the Company and such  purchasers to
which  the  Trustee  has not  consented  in  writing,  including  the  costs and
expenses,  including  reasonable  legal  fees,  incurred  by the  Trustee in the
defense  of any claim or  liability  arising  out of or in  connection  with the
exercise  or  performance  of any of its  powers,  duties,  responsibilities  or
obligations under this Indenture.

         Section 3.5.         Redemption at Option of Holders .

                       (a)    If there shall occur a  Fundamental  Change,  then
each Noteholder  shall have the right, at such holder's  option,  to require the
Company to redeem all of such holder's  Notes, or any portion thereof that is an
integral  multiple  of $1,000  principal  amount,  on the date (the  "Repurchase
Date") that is thirty (30) days after the date of the Company Notice (as defined
in Section 3.5(b) below) of such Fundamental Change (or, if such 30th day is not
a Business Day, the next succeeding  Business Day). Such repayment shall be made
at 106.000%  from the date of initial  issuance of the Notes until May 14, 1998;
105.143% from May 15, 1988 until May 14, 1999;  104.286% from May 15, 1999 until
May 17, 2000;  103.429%  from May 18, 2000 until May 14, 2001 and  thereafter at
the following prices  (expressed as percentages of the principal  amount) in the
event of a Fundamental Change occurring during the 12-month period beginning May
15:

                  Year                           Percentage
                  ----                           ----------
                  2001............................102.571%

                  2002............................101.714%

                  2003............................100.857%


and 100% at May 15, 2004; provided, that if the Applicable Price with respect to
the  Fundamental  Change is less than the Reference  Market  Price,  the Company
shall  redeem  such Notes at a price

                                      -25-
<PAGE>

equal to the foregoing  redemption price multiplied by the fraction  obtained by
dividing the Applicable  Price by the Reference  Market Price. In each case, the
Company shall also pay to such holders accrued  interest to, but excluding,  the
Repurchase Date on the redeemed Notes; provided,  that if such repayment date is
May 15 or November 15, then the  interest  payable on such date shall be paid to
the holder of record of the Note on the next  preceding  April 30 or October 31,
respectively.

         Upon  presentation of any Note 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 Note or Notes, of authorized denominations, in
principal amount equal to the unredeemed portion of the Notes so presented.

                          (b)       On   or  before  the  tenth  day  after  the
occurrence of a Fundamental Change, the Company,  or, at its request (which must
be received by the Trustee at least five (5) Business Days prior to the date the
Trustee is requested to give notice as described below), the Trustee in the name
of and at the  expense of the  Company,  shall mail or cause to be mailed to all
holders of record on the date of the  Fundamental  Change a notice (the "Company
Notice") of the  occurrence  of such  Fundamental  Change and of the  redemption
right at the option of the  holders  arising as a result  thereof.  Such  notice
shall be  mailed  in the  manner  and with the  effect  set  forth in the  first
paragraph of Section  3.2. The Company  shall also deliver a copy of the Company
Notice to the Trustee at such time as it is mailed to Noteholders.

         Each Company Notice shall specify the  circumstances  constituting  the
Fundamental Change, the Repurchase Date, the price at which the Company shall be
obligated to redeem Notes,  the latest time on the Repurchase  Date by which the
holder must exercise the redemption right (the  "Fundamental  Change  Expiration
Time"),  that the holder shall have the right to withdraw any Notes  surrendered
prior to the Fundamental  Change Expiration Time, a description of the procedure
which a Noteholder must follow to exercise such redemption right and to withdraw
any surrendered Notes, the place or places where the holder is to surrender such
holder's  Notes,  and  the  amount  of  interest  accrued  on  each  Note to the
Repurchase Date.

         No failure of the Company to give the  foregoing  notices and no defect
therein shall limit the Noteholders' redemption rights or affect the validity of
the proceedings for the repurchase of the Notes pursuant to this Section 3.5.

                          (c)       For  a Note to be so repaid at the option of
the  holder,  the  Company  must  receive at the office or agency of the Company
maintained  for that purpose in the Borough of  Manhattan,  The City of New York
or, at the option of such holder, the Corporate Trust Office, such Note with the
form  entitled  "Option to Elect  Repayment  Upon A  Fundamental  Change" on the
reverse  thereof  duly  completed,  together  with such Notes duly  endorsed for
transfer,  on or before the Fundamental Change Expiration Time. All questions as
to the validity,  eligibility  (including time of receipt) and acceptance of any
Note for repayment shall be determined by the Company, whose determination shall
be final and binding absent manifest error.

                          (d)       On  or prior  to the  Repurchase  Date,  the
Company will deposit with the Trustee or with one or more paying  agents (or, if
the Company is acting as its own paying agent, set aside,  segregate and hold in
trust as provided in Section 5.4) an amount of money  sufficient to repay on the
Repurchase  Date all the  Notes to be  repaid  on such  date at the  appropriate
redemption  price,  together  with  accrued  interest  to  (but  excluding)  the
Repurchase Date;  provided,  that if such payment is made on the Repurchase Date
it must be received by the Trustee or paying agent, as the case may be, by 10:00
a.m.  New York City  time,  on such  date.  Payment  for Notes  surrendered  for
redemption (and not withdrawn) prior to the Fundamental  Change  Expiration Time
will be made promptly (but in no event more than three Business Days)  following
the  Repurchase  Date by mailing checks for the amount payable to the holders of
such Notes  entitled  thereto as they shall appear on the registry  books of the
Company.

                          (e)       In   the  case  of  consolidation,   merger,
conveyance, transfer or lease to which Section 15.6 applies, in which the Common
Stock of the  Company  is  changed or  exchanged  as a result  into the right to
receive securities, cash or other property which includes shares of Common Stock
of the Company or another Person that are, or upon issuance will be, traded on a
United  States  national  securities  exchange  or  approved  for  trading on an
established automated  over-the-counter  trading market in the United States and
such shares  constitute at the time such change or exchange becomes effective in
excess of 50% of the aggregate  fair market value of such  securities,  cash and
other  property (as  determined  by the Company,  which  determination  shall be
conclusive  and  binding),  then the  Person  formed  by such  consolidation  or
resulting  from such merger or which  acquires such assets,  as the case may be,
shall execute and deliver to the Trustee a supplemental  indenture  (which shall
comply with the Trust Indenture Act as in force at the date of execution of such
supplemental  indenture)  modifying the provisions of this Indenture relating to
the right of holders of the Notes to cause the Company to  repurchase  the Notes
following a Fundamental  Change,  including  without  limitation  the applicable
provisions  of this Section 3.5 and the  definitions  of the  Applicable  Price,
Common Stock, Fundamental Change and Reference Market Price, as appropriate,  as
determined in good faith by the Company (which determination shall be conclusive
and binding),  to make such provisions  apply to the common stock and the issuer
thereof if  different  from the Company and Common Stock of the Company (in lieu
of the Company and the Common Stock of the Company).

                                   ARTICLE IV

                             SUBORDINATION OF NOTES

         Section 4.1  Agreement of  Subordination  . The Company  covenants  and
agrees,  and each holder of Notes  issued  hereunder by his  acceptance  thereof
likewise  covenants  and agrees,  that all Notes shall be issued  subject to the
provisions  of this Article IV; and each Person  holding any Note,  whether upon
original issue or upon  transfer,  assignment or exchange  thereof,  accepts and
agrees to be bound by such  provisions.  The Notes will be "pari passu" with the
Company's 7 3/4% Convertible Subordinated Debentures due 2001.

                                      -27-

         The payment of the principal of,  premium,  if any, and interest on all
Notes  (including,  but not limited to, the redemption price with respect to the
Notes called for  redemption  in  accordance  with Section 3.2 or submitted  for
redemption  in  accordance  with Section 3.5, as the case may be, as provided in
the  Indenture)  issued  hereunder  shall,  to the  extent  and  in  the  manner
hereinafter set forth,  be  subordinated  and subject in right of payment to the
prior payment in full of all Senior  Indebtedness,  whether  outstanding  at the
date of this Indenture or thereafter incurred.

         No  provision of this Article IV shall  prevent the  occurrence  of any
default or Event of Default hereunder.

         Section 4.2.  Payments to  Noteholders  . No payment shall be made with
respect to the  principal  of, or  premium,  if any,  or  interest  on the Notes
(including,  but not limited to, the redemption  price with respect to the Notes
to be called for  redemption  in  accordance  with Section 3.2 or submitted  for
redemption  in  accordance  with Section 3.5, as the case may be, as provided in
the  Indenture),  except  payments  and  distributions  made by the  Trustee  as
permitted by the first or second paragraph of Section 4.5, if:

                  (i) a default in the payment of  principal,  premium,  if any,
         interest,  rent or other obligations in respect of Senior  Indebtedness
         occurs and is continuing  (or, in the case of Senior  Indebtedness  for
         which there is a period of grace,  in the event of such a default  that
         continues  beyond  the  period  of  grace,  if  any,  specified  in the
         instrument or lease  evidencing such Senior  Indebtedness),  unless and
         until such default shall have been cured or waived or shall have ceased
         to exist; or

                  (ii) a default,  other than a payment  default,  on Designated
         Senior  Indebtedness occurs and is continuing that then permits holders
         of such Designated  Senior  Indebtedness to accelerate its maturity and
         the  Trustee  receives  a notice of the  default (a  "Payment  Blockage
         Notice") from a Representative or the Company.

         If the Trustee  receives any Payment Blockage Notice pursuant to clause
(ii) above,  no  subsequent  Payment  Blockage  Notice  shall be  effective  for
purposes  of this  Section  unless  and until (A) at least 365 days  shall  have
elapsed  since  the  initial  effectiveness  of the  immediately  prior  Payment
Blockage Notice, and (B) all scheduled payments of principal,  premium,  if any,
and interest on the Notes that have come due have been paid in full in cash.  No
nonpayment default that existed or was continuing on the date of delivery of any
Payment  Blockage  Notice to the Trustee  shall be, or be made,  the basis for a
subsequent Payment Blockage Notice.

         The  Company may and shall  resume  payments  on and  distributions  in
respect of the Notes upon the earlier of:

         (1) the date upon which the default is cured or waived or ceases to
 exist, or
 
                                      -28-
<PAGE>

         (2) in the case of a default referred to in clause (ii) above, 179 days
after the Payment Blockage Notice is received if the maturity of such Designated
Senior  Indebtedness has not been accelerated,  unless this Article IV otherwise
prohibits  the  payment  or   distribution  at  the  time  of  such  payment  or
distribution.

         Upon any  payment  by the  Company,  or  distribution  of assets of the
Company of any kind or character,  whether in cash,  property or securities,  to
creditors upon any dissolution or winding-up or liquidation or reorganization of
the Company,  whether  voluntary or involuntary  or in  bankruptcy,  insolvency,
receivership  or other  proceedings,  all  amounts due or to become due upon all
Senior  Indebtedness  shall  first  be paid in  full  in cash or  other  payment
satisfactory to the holders of such Senior  Indebtedness,  or payment thereof in
accordance with its terms provided for in cash or other payment  satisfactory to
the holders of such Senior Indebtedness before any payment is made on account of
the principal  of,  premium,  if any, or interest on the Notes (except  payments
made pursuant to Article XIII from monies  deposited  with the Trustee  pursuant
thereto prior to commencement of proceedings for such  dissolution,  winding-up,
liquidation or  reorganization);  and upon any such dissolution or winding-up or
liquidation  or  reorganization  of  the  Company  or  bankruptcy,   insolvency,
receivership or other proceeding, any payment by the Company, or distribution of
assets of the  Company of any kind or  character,  whether in cash,  property or
securities,  to which the holders of the Notes or the Trustee would be entitled,
except for the  provisions  of this Article IV, shall  (except as  aforesaid) be
paid by the  Company  or by any  receiver,  trustee in  bankruptcy,  liquidating
trustee,  agent or other Person making such payment or  distribution,  or by the
holders of the Notes or by the Trustee under this  Indenture if received by them
or it, directly to the holders of Senior  Indebtedness (pro rata to such holders
on the  basis of the  respective  amounts  of Senior  Indebtedness  held by such
holders,   or  as  otherwise  required  by  law  or  a  court  order)  or  their
representative  or  representatives,  or to the  trustee or  trustees  under any
indenture pursuant to which any instruments  evidencing any Senior  Indebtedness
may have been issued,  as their respective  interests may appear,  to the extent
necessary  to pay all  Senior  Indebtedness  in full,  in cash or other  payment
satisfactory to the holders of such Senior Indebtedness,  after giving effect to
any  concurrent  payment  or  distribution  to or  for  the  holders  of  Senior
Indebtedness,  before any payment or  distribution is made to the holders of the
Notes or to the Trustee.

         For  purposes  of this  Article  IV,  the  words,  "cash,  property  or
securities"  shall not be deemed to  include  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 at least to the extent provided in this Article IV with respect
to the Notes to the payment of all Senior  Indebtedness which may at the time be
outstanding;  provided,  that (i) the Senior  Indebtedness is assumed by the new
corporation, if any, resulting from any reorganization or readjustment, and (ii)
the rights of the holders of Senior  Indebtedness  (other than leases  which are
not assumed by the Company or the new corporation,  as the case may be) are not,
without  the  consent  of  such  holders,  altered  by  such  reorganization  or
readjustment.  The  consolidation  of the  Company  with,  or the  merger of the
Company into,  another  corporation  or the  liquidation  or  dissolution of the
Company following the conveyance or transfer of its

                                      -29-
<PAGE>

property as an entirety, or substantially as an entirety, to another corporation
upon the terms and conditions  provided for in Article XII shall not be deemed a
dissolution,  winding-up, liquidation or reorganization for the purposes of this
Section 4.2 if such other  corporation  shall, as a part of such  consolidation,
merger,  conveyance or transfer,  comply with the  conditions  stated in Article
XII.

         In the event of the  acceleration  of the Notes  because of an Event of
Default,  no payment or distribution  shall be made to the Trustee or any holder
of Notes in respect of the  principal  of,  premium,  if any, or interest on the
Notes  (including,  but not limited to, the redemption price with respect to the
Notes called for  redemption  in  accordance  with Section 3.2 or submitted  for
redemption  in  accordance  with Section 3.5, as the case may be, as provided in
the  Indenture),  except  payments  and  distributions  made by the  Trustee  as
permitted  by the first or second  paragraph  of Section  4.5,  until all Senior
Indebtedness has been paid in full in cash or other payment  satisfactory to the
holders of Senior  Indebtedness or such  acceleration is rescinded in accordance
with the terms of this Indenture. If payment of the Notes is accelerated because
of an Event of Default,  the Company  shall  promptly  notify  holders of Senior
Indebtedness of the acceleration.

         In the  event  that,  notwithstanding  the  foregoing  provisions,  any
payment  or  distribution  of assets of the  Company  or any kind or  character,
whether in cash, property or securities (including,  without limitation,  by way
of setoff or otherwise),  prohibited by the foregoing,  shall be received by the
Trustee or the holders of the Notes  before all Senior  Indebtedness  is paid in
full in  cash or  other  payment  satisfactory  to the  holders  of such  Senior
Indebtedness,  or provision is made for such payment  thereof in accordance with
its terms in cash or other  payment  satisfactory  to the holders of such Senior
Indebtedness,  such  payment  or  distribution  shall be held in  trust  for the
benefit  of and  shall  be paid  over or  delivered  to the  holders  of  Senior
Indebtedness or their  representative or  representatives,  or to the trustee or
trustees under any indenture  pursuant to which any  instruments  evidencing any
Senior  Indebtedness  may have been issued,  as their  respective  interests may
appear, as calculated by the Company, for application to the payment of a Senior
Indebtedness  remaining  unpaid  to  the  extent  necessary  to pay  all  Senior
Indebtedness  in full in cash or other  payment  satisfactory  to the holders of
such Senior  Indebtedness,  after  giving  effect to any  concurrent  payment or
distribution to or for the holders of such Senior Indebtedness.

         Nothing in this  Section 4.2 shall apply to claims of, or payments  to,
the Trustee  under or pursuant to Section 8.6. This Section 4.2 shall be subject
to the further provisions of Section 4.5.

         Section 4.3.  Subrogation  of Notes.  Subject to the payment in full of
all  Senior  Indebtedness,  the  rights of the  holders  of the  Notes  shall be
subrogated to the extent of the payments or distributions made to the holders of
such Senior Indebtedness  pursuant to the provisions of this Article IV (equally
and ratably  with the holders of all  indebtedness  of the Company  which by its
express  terms  is  subordinated  to  other   indebtedness  of  the  Company  to
substantially  the same extent as the Notes are  subordinated and is entitled to
like rights of subrogation) to the rights of the holders of Senior  Indebtedness
to receive  payments or

                                      -30-
<PAGE>

distributions of cash,  property or securities of the Company  applicable to the
Senior  Indebtedness until the principal,  premium,  if any, and interest on the
Notes  shall be paid in full;  and,  for the  purposes of such  subrogation,  no
payments or distributions to the holders of the Senior Indebtedness of any cash,
property or securities to which the holders of the Notes or the Trustee would be
entitled  except for the  provisions  of this  Article  IV, and no payment  over
pursuant  to the  provisions  of this  Article  IV, to or for the benefit of the
holders of Senior Indebtedness by holders of the Notes or the Trustee, shall, as
between the Company,  its creditors  other than holders of Senior  Indebtedness,
and the holders of the Notes,  be deemed to be a payment by the Company to or on
account of the Senior  Indebtedness;  and no payments or  distributions of cash,
property  or  securities  to or for the  benefit  of the  holders  of the  Notes
pursuant to the subrogation provisions of this Article IV, which would otherwise
have been paid to the  holders of Senior  Indebtedness,  shall be deemed to be a
payment by the Company to or for the account of the Notes. It is understood that
the  provisions of this Article IV are and are intended  solely for the purposes
of defining  the relative  rights of the holders of the Notes,  on the one hand,
and the holders of the Senior Indebtedness, on the other hand.

         Nothing  contained in this Article IV or elsewhere in this Indenture or
in the Notes is intended to or shall impair, as among the Company, its creditors
other than the holders of Senior Indebtedness, and the holders of the Notes, the
obligation of the Company,  which is absolute and  unconditional,  to pay to the
holders of the Notes the principal of (and premium,  if any) and interest on the
Notes as and when the same shall become due and payable in accordance with their
terms,  or is intended to or shall affect the relative  rights of the holders of
the Notes 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  Note  from  exercising  all  remedies  otherwise  permitted  by
applicable law upon default under this Indenture, subject to the rights, if any,
under this Article IV 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 payment or distribution  of assets of the Company  referred to
in this Article IV, the Trustee,  subject to the  provisions of Section 8.1, and
the holders of the Notes shall be entitled to rely upon any order or decree made
by any court of competent  jurisdiction in which such  bankruptcy,  dissolution,
winding-up,   liquidation  or  reorganization  proceedings  are  pending,  or  a
certificate of the receiver,  trustee in bankruptcy,  liquidating trustee, agent
or other person making such payment or distribution, delivered to the Trustee or
to the  holders  of the  Notes,  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 and all other facts pertinent thereto or to this Article IV.

         Section 4.4.  Authorization to Effect  Subordination.  Each holder of a
Note by the holder's  acceptance  thereof  authorizes and directs the Trustee on
the holder's  behalf to take such action as may be necessary or  appropriate  to
effectuate  the  subordination  as provided in this  Article IV and appoints the
Trustee to act as the holder's  attorney-in-fact  for any and all such purposes.
If the  Trustee  does not  file a proper  proof of claim or proof of debt in the
form

                                      -31-
<PAGE>

required in any proceeding referred to in the third paragraph of Section
7.2  hereof  at least 30 days  before  the  expiration  of the time to file such
claim,  the  holders of any Senior  Indebtedness  or their  representatives  are
hereby  authorized to file an appropriate claim for and on behalf of the holders
of the Notes.

         Section 4.5.  Notice to Trustee . The Company shall give prompt written
notice in the form of an Officers'  Certificate to a Responsible  Officer of the
Trustee  and to any paying  agent of any fact known to the  Company  which would
prohibit  the making of any payment of monies to or by the Trustee or any paying
agent in respect of the Notes  pursuant to the  provisions  of this  Article IV.
Notwithstanding the provisions of this Article IV or any other provision of this
Indenture,  the Trustee shall not be charged with  knowledge of the existence of
any facts which would  prohibit the making of any payment of monies to or by the
Trustee in respect of the Notes  pursuant to the  provisions of this Article IV,
unless and until a  Responsible  Officer  of the  Trustee  shall  have  received
written  notice  thereof at the Corporate  Trust Office from the Company (in the
form of an Officers'  Certificate) or a Representative or a holder or holders of
Senior  Indebtedness or from any trustee thereof;  and before the receipt of any
such written  notice,  the Trustee,  subject to the  provisions  of Section 8.1,
shall be entitled in all respects to assume that no such facts exist;  provided,
that if on a date not fewer than one  Business  Day prior to the date upon which
by the  terms  hereof  any  such  monies  may  become  payable  for any  purpose
(including,  without limitation, the payment of the principal of, or premium, if
any, or interest on any Note) the Trustee shall not have received,  with respect
to such monies,  the notice  provided for in this  Section 4.5,  then,  anything
herein  contained to the contrary  notwithstanding,  the Trustee shall have full
power and  authority to receive such monies and to apply the same to the purpose
for which they were  received,  and shall not be  affected  by any notice to the
contrary which may be received by it on or after such prior date.

         Notwithstanding  anything in this Article IV to the  contrary,  nothing
shall prevent any payment by the Trustee to the Noteholders of monies  deposited
with it pursuant to Section  13.1,  and any such payment shall not be subject to
the provisions of Section 4.1 or 4.2.

         The  Trustee,  subject  to the  provisions  of  Section  8.1,  shall be
entitled to rely on the delivery to it of a written  notice by a  Representative
or a person  representing  himself to be a holder of Senior  Indebtedness  (or a
trustee on behalf of such holder) to  establish  that such notice has been given
by a Representative or a holder of Senior Indebtedness or a trustee on behalf of
any such holder or holders.  In the event that the  Trustee  determines  in good
faith that further  evidence is required with respect to the right of any person
as a holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this  Article  IV, the  Trustee  may request  such person to furnish
evidence  to the  reasonable  satisfaction  of the  Trustee  as to the amount of
Senior  Indebtedness  held by such  person,  the extent to which such  person is
entitled to  participate  in such  payment or  distribution  and any other facts
pertinent  to the  rights of such  person  under  this  Article  IV, and if such
evidence  is not  furnished  the  Trustee  may defer any  payment to such person
pending  judicial  determination  as to the right of such person to receive such
payment.

         Section 4.6. Trustee's Relation to Senior Indebtedness . The Trustee in
its  individual  capacity  shall be entitled to all the rights set forth in this
Article IV in respect of any Senior  Indebtedness at any time held by it, to the
same extent as any other holder of Senior  Indebtedness,  and nothing in Section
8.13 or  elsewhere  in this  Indenture  shall  deprive the Trustee of any of its
rights as such holder.

         With  respect  to the  holders  of  Senior  Indebtedness,  the  Trustee
undertakes to perform or to observe only such of its  covenants and  obligations
as are  specifically  set forth in this Article IV, and no implied  covenants or
obligations  with  respect to the holders of Senior  Indebtedness  shall be read
into this Indenture against the Trustee.  The Trustee shall not be deemed to owe
any fiduciary  duty to the holders of Senior  Indebtedness  and,  subject to the
provisions  of Section  8.1,  the  Trustee  shall not be liable to any holder of
Senior  Indebtedness  if it shall pay over or deliver  to holders of Notes,  the
Company  or any other  person  money or  assets  to which  any  holder of Senior
Indebtedness shall be entitled by virtue of this Article IV or otherwise.

         Section 4.7. No Impairment of  Subordination  . No right of any present
or future holder of any Senior  Indebtedness to enforce  subordination as herein
provided  shall at any time in any way be  prejudiced  or impaired by any act or
failure to act on the part of the  Company  or by any act or failure to act,  in
good faith, by any such holder,  or by any noncompliance by the Company with the
terms,  provisions and covenants of this Indenture,  regardless of any knowledge
thereof which any such holder may have or otherwise be charged with.

         Section 4.8. Certain  Conversions  Deemed Payment . For the purposes of
this Article IV only,  (1) the issuance and delivery of junior  securities  upon
conversion  of Notes in  accordance  with  Article  XV shall  not be  deemed  to
constitute a payment or distribution on account of the principal of (or premium,
if any) or interest on Notes or on account of the purchase or other  acquisition
of  Notes,  and (2) the  payment,  issuance  or  delivery  of  cash  (except  in
satisfaction  of  fractional  shares  pursuant  to Section  15.3),  property  or
securities  (other than junior  securities)  upon  conversion of a Note shall be
deemed to constitute  payment on account of the principal of such Note.  For the
purposes of this Section 4.8, the term "junior  securities"  means (a) shares of
any stock of any class of the Company,  or (b)  securities  of the Company which
are  subordinated  in right of payment to all Senior  Indebtedness  which may be
outstanding  at  the  time  of  issuance  or  delivery  of  such  securities  to
substantially  the same extent as, or to a greater extent than, the Notes are so
subordinated as provided in this Article.  Nothing  contained in this Article IV
or elsewhere in this  Indenture or in the Notes is intended to or shall  impair,
as among the Company,  its creditors  other than holders of Senior  Indebtedness
and the  Noteholders,  the right,  which is absolute and  unconditional,  of the
Holder of any Note to convert such Note in accordance with Article XV.

         Section 4.9.  Article  Applicable to Paying Agents.  If at any time any
paying agent other than the Trustee shall have been appointed by the Company and
be then acting  hereunder,  the term  "Trustee"  as used in this  Article  shall
(unless the  context  otherwise  requires)  be  construed  as  extending  to and
including  such  paying  agent  within its  meaning as fully for all intents and

                                      -33-
<PAGE>

purposes as if such paying agent were named in this Article in addition to or in
place of the Trustee; provided, however, that the first paragraph of Section 4.5
shall not apply to the  Company or any  Affiliate  of the  Company if it or such
Affiliate acts as paying agent.

         Section  4.10.  Senior  Indebtedness  Entitled to Rely.  The holders of
Senior   Indebtedness   (including,   without   limitation,   Designated  Senior
Indebtedness)  shall  have the  right  to rely  upon  this  Article  IV,  and no
amendment or modification of the provisions  contained herein shall diminish the
rights of such holders unless such holders shall have agreed in writing thereto.

         Section 4.11.  Reliance on Judicial Order or Certificate of Liquidating
Agent.  Upon any payment or distribution of assets of the Company referred to in
this  Article,  the Trustee,  subject to the  provisions of Section 7.1, and the
Holders of the Notes shall be entitled to rely upon any order or decree  entered
by any court of competent  jurisdiction  in which such  insolvency,  bankruptcy,
receivership,  liquidation,  reorganization,  dissolution, winding up or similar
case or proceeding is pending,  or a certificate  of the trustee in  bankruptcy,
liquidating trustee, custodian, receiver, assignee for the benefit of creditors,
agent or other  person  making such  payment or  distribution,  delivered to the
Trustee or to the  Holders of the Notes,  for the  purpose of  ascertaining  the
persons entitled to participate in such payment or distribution,  the holders of
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

offices or agencies where the Notes may be presented or  surrendered  for any or
all such purposes and may from time to time rescind such designations; provided,

of its  obligation  to maintain an office or agency in the Borough of Manhattan,
The City of New York,  for such  purposes.  The Company will give prompt written
notice to any such  designation  or rescission and of any change in the location
of any such other office or agency.

                  trust for the benefit of the holders of the Notes;

                           (2)  that it will  give  the  Trustee  notice  of any
                  failure by the Company (or by any other  obligor on the Notes)
                  to make any payment of the  principal of and premium,  if any,

         The  Company  shall,  on or before each due date of the  principal  of,
premium,  if any, or interest on the Notes,  deposit with the paying agent a sum
sufficient to pay such principal, premium, if any, or interest, and (unless such
paying agent is the Trustee) the Company will promptly notify the Trustee of any
failure to take such action;  provided,  that if such deposit is made on the due
date,  such deposit shall be received by the paying agent by 10:00 a.m. New York
City time, on such date.

before each due date of the  principal of,  premium,  if any, or interest on the

any payment of the principal of, premium,  if any, or interest on the Notes when
the same shall become due and payable.

            (c) Anything in this  Section 5.4 to the  contrary  notwithstanding,
the Company may, at any time,  for the purpose of obtaining a  satisfaction  and
discharge of this Indenture, or for any other reason, pay or cause to be paid to
the Trustee all sums held in trust by the Company or any paying agent  hereunder

any paying  agent to the  Trustee,  the  Company or such  paying  agent shall be
released from all further liability with respect to such sums.

            (d) Anything in this  Section 5.4 to the  contrary  notwithstanding,

to Section 13 or 15(d) under the Exchange Act,  make  available to any holder or
beneficial  holder of Notes or any Common Stock issued upon  conversion  thereof
which continue to be Restricted  Securities in connection  with any sale thereof
and any prospective  purchaser of Notes or such Common Stock from such holder or
beneficial  holder,  the information  required pursuant to Rule 144A(d)(4) under
the  Securities  Act upon the request of any holder or beneficial  holder of the
Notes or such Common Stock and it will take such further action as any holder or
beneficial holder of such Notes or such Common Stock may reasonably request, all
to the extent  required  from time to time to enable such  holder or  beneficial
holder  to sell  its  Notes or  Common  Stock  without  registration  under  the
Securities Act within the limitation of the exemption  provided by Rule 144A, as
such Rule may be amended  from time to time.  Upon the  request of any holder or

deliver to such holder a written  statement as to whether it has  complied  with
such requirements.

         Section 5.7. Stay, Extension and Usury Laws . The Company covenants (to
the  extent  that it may  lawfully  do so) that it shall not at any time  insist
upon,  plead, or in any manner whatsoever claim or take the benefit or advantage

forgive  the  Company  from  paying all or any  portion of the  principal  of or
interest on the Notes as contemplated  herein,  wherever enacted,  now or at any
time hereafter in force, or which may affect the covenants or the performance of

will not, by resort to any such law,  hinder,  delay or impede the  execution of
any power  herein  granted  to the  Trustee,  but will  suffer  and  permit  the
execution of every such power as though no such law has been enacted.

of  any  administrative  or  governmental  body)  shall  have  occurred  and  be
continuing:

            (a) default in the payment of any  installment  of interest upon any
of the Notes as and when the same shall become due and payable,  and continuance
of such default for a period of thirty (30) days, whether or not such payment is
permitted under Article IV hereof; or

                                      -39-
<PAGE>


            (b) default in the payment of the principal of and premium,  if any,
on any of the Notes as and when the same shall become due and payable  either at
maturity  or in  connection  with any  redemption  pursuant  to Article  III, by
acceleration  or  otherwise,  whether  or not such  payment is  permitted  under
Article IV hereof; or

            (c)  failure on the part of the  Company  duly to observe or perform
any other of the covenants or agreements on the part of the Company in the Notes
or in this  Indenture  (other  than a covenant  or  agreement a default in whose
performance or whose breach is elsewhere in this Section 7.1 specifically  dealt
with)  continued for a period of sixty (60) days after the date on which written
notice of such  failure,  requiring  the Company to remedy the same,  shall have
been given to the Company by the  Trustee,  or to the Company and a  Responsible
Officer  of the  Trustee by the  holders  of at least 25  percent  in  aggregate
principal amount of the Notes at the time  outstanding  determined in accordance
with Section 9.4; or

            (d) the Company shall commence a voluntary case or other  proceeding
seeking  liquidation,  reorganization  or other relief with respect to itself or
its debts under any bankruptcy, insolvency or other similar law now or hereafter
in effect  or  seeking  the  appointment  of a  trustee,  receiver,  liquidator,
custodian  or  other  similar  official  of it or any  substantial  part  of its
property, or shall consent to any such relief or to the appointment of or taking
possession  by any such  official  in an  involuntary  case or other  proceeding
commenced  against  it, or shall make a general  assignment  for the  benefit of
creditors, or shall fail generally to pay its debts as they become due; or

            (e) an  involuntary  case or other  proceeding  shall  be  commenced

now or hereafter in effect or seeking the  appointment  of a trustee,  receiver,
liquidator, custodian or other similar official of it or any substantial part of
its  property,  and such  involuntary  case or  other  proceeding  shall  remain
undismissed and unstated for a period of ninety (90) consecutive days;

then, and in each and every such case (other than an Event of Default  specified
in Section  7.1(d) or (e)),  unless the principal of all of the Notes shall have
already  become due and  payable,  either the Trustee or the holders of not less
than 25  percent in  aggregate  principal  amount of the Notes then  outstanding
hereunder determined in accordance with Section 9.4, by notice in writing to the
Company (and to the Trustee if given by Noteholders),  may declare the principal

Section  7.1(d) or (e) occurs,  the  principal of all the Notes and the interest
accrued thereon shall be immediately and  automatically  due and payable without
necessity  of  further  action.  This  provision,  however,  is  subject  to the

so declared due and  payable,  and before any judgment or decree for the payment
of the monies due shall have been obtained or entered as  hereinafter  provided,

installments  of interest  upon all Notes and the  principal of and premium,  if
any,  on any and all  Notes  which  shall  have  become  due  otherwise  than by
acceleration  (with interest on overdue  installments of interest (to the extent
that payment of such interest is enforceable  under  applicable law) and on such
principal  and premium,  if any, at the rate borne by the Notes,  to the date of
such payment or deposit) and amounts due to the Trustee pursuant to Section 8.6,
and if any and all defaults under this  Indenture,  other than the nonpayment of
principal of and premium, if any, and accrued interest on Notes which shall have
become due by acceleration,  shall have been cured or waived pursuant to Section
7.7 -- then and in every  such  case the  holders  of a  majority  in  aggregate
principal amount of the Notes then outstanding, by written notice to the Company
and to the Trustee,  may waive all defaults or Events of Default and rescind and
annul such  declaration and its  consequences;  but no such waiver or rescission
and annulment shall extend to or shall affect any subsequent default or Event of
Default, or shall impair any right consequent thereon.  The Company shall notify
a Responsible  Officer of the Trustee,  promptly upon becoming aware thereof, of
any Event of Default.

         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 waiver or  rescission  and  annulment or for any other reason or
shall have been determined adversely to the Trustee, then and in every such case
the  Company,   the  holders  of  Notes,  and  the  Trustee  shall  be  restored
respectively to their several  positions and rights  hereunder,  and all rights,
remedies  and powers of the Company,  the holders of the Notes,  and the Trustee
shall continue as though no such proceeding had been taken.

         Section 7.2. Payments of Notes on Default;  Suit Therefor . The Company
covenants  that  (a) in  case  default  shall  be  made  in the  payment  of any
installment  of interest upon any of the Notes as and when the same shall become
due and payment,  and such default  shall have  continued for a period of thirty
(30) days,  or (b) in case default shall be made in the payment of the principal
of or  premium,  if any,  on any of the  Notes as and when the same  shall  have
become due and payable,  whether at maturity of the Notes or in connection  with
any  redemption,  by or under this  Indenture  declaration or otherwise -- then,
upon demand of the Trustee, the Company will pay to the Trustee, for the benefit
of the  holders of the Notes,  the whole  amount that then shall have become due
and payable on all such Notes for principal and premium, if any, or interest, or
both, as the case may be, with interest upon the overdue  principal and premium,
if any and (to the extent that  payment of such  interest is  enforceable  under
applicable  law) upon the overdue  installments of interest at the rate borne by
the Notes; and, in addition thereto,  such further amount as shall be sufficient
to cover the costs and expenses of collection, including reasonable compensation
to the  Trustee,  its  agents,  attorneys  and  counsel,  and  any  expenses  or
liabilities  incurred by the Trustee hereunder other than through its negligence
or bad  faith.  Until  such  demand  by the  Trustee,  the  Company  may pay the
principal  of and premium,  if any, and interest on the Notes to the  registered
holders, whether or not the Notes are overdue.

                                      -41-
<PAGE>


         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 actions or  proceedings  at law or in
equity for the  collection of the sums so due and unpaid,  and may prosecute any
such action or proceeding to judgment or final decree,  and may enforce any such
judgment or final decree  against the Company or any other  obligor on the Notes
and collect in the manner  provided by law out of the property of the Company or
any other obligor on the Notes wherever  situated the monies adjudged or decreed
to be payable.

         In the case there shall be pending  proceedings  for the  bankruptcy or
for the  reorganization  of the Company or any other  obligor on the Notes under
Title 11 of the United  States Code, or any other  applicable  law, or in case a
receiver,  assignee  or trustee in  bankruptcy  or  reorganization,  liquidator,
sequestrator  or  similar  official  shall  have  been  appointed  for or  taken
possession of the Company or such other obligor,  the property of the Company or
such other obligor, or in the case of any other judicial proceedings relative to
the  Company  or such  other  obligor  upon the Notes,  or to the  creditors  or
property of the Company or such other  obligor,  the  Trustee,  irrespective  of
whether  the  principal  of the Notes  shall then be due and  payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand pursuant to the provisions of this Section 7.2, shall
be entitled and empowered,  by intervention in such proceedings or otherwise, to
file and prove a claim or claims for the whole amount of principal,  premium, if
any, and interest owing and unpaid in respect of the Notes,  and, in case of any
judicial proceedings, to file such proofs of claim and other papers or documents
as may be  necessary or advisable in order to have the claims of the Trustee and
of the Noteholders allowed in such judicial  proceedings relative to the Company
or any other  obligor  on the  Notes,  its or their  creditors,  or its or their
property,  and to collect and receive  any monies or other  property  payable or
deliverable  on any such claims,  and to distribute the same after the deduction
of any amounts due the Trustee under Section 8.6; and any receiver,  assignee or
trustee  in  bankruptcy  or  reorganization,  liquidator,  custodian  or similar
official is hereby  authorized by each of the  Noteholders to make such payments
to the Trustee,  and, in the event that the Trustee  shall consent to the making
of such payments  directly to the Noteholders,  to pay to the Trustee any amount
due  it for  reasonable  compensation,  expenses,  advances  and  disbursements,
including  counsel fees incurred by it up to the date of such  distribution.  To
the extent that such payment of reasonable compensation,  expenses, advances and
disbursements  out of the estate in any such proceedings shall be denied for any
reason, payment of the same shall be secured by a lien on, and shall be paid out
of, any and all distributions,  dividends, monies, securities and other property
which the holders of the Notes may be  entitled to receive in such  proceedings,
whether in  liquidation  or under any plan of  reorganization  or arrangement or
otherwise.

         All rights of action and of asserting  claims under this Indenture,  or
under any of the Notes, may be enforced by the Trustee without the possession of
any of the Notes,  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 as  trustee  of an  express  trust,  and any
recovery of judgment  shall,  after  provision for the payment of the reasonable
compensation,  expenses,

                                      -42-
<PAGE>

disbursements  and advances of the Trustee,  its agents and counsel,  be for the
ratable benefit of the holders of the Notes.

         In any  proceedings  brought  by the  Trustee  (and in any  proceedings
involving the  interpretation  of any  provision of this  Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the holders
of the Notes,  and it shall not be  necessary  to make any  holders of the Notes
parties to any such proceedings.

         Section 7.3.  Application  of Monies  Collected by Trustee.  Any monies
collected  by the Trustee  pursuant to this  Article VII shall be applied in the
order following,  at the date or dates fixed by the Trustee for the distribution
of such monies, upon presentation of the several Notes, and stamping thereon the
payment, if only partially paid, and upon surrender thereof, if fully paid:

                  First:  To the payment of all amounts due the Trustee under
         Section 8.6;

                  Second:  Subject to the  provisions of Article IV, in case the
         principal  of the  outstanding  Notes  shall not have become due and be
         unpaid, to the payment of interest on the Notes in default in the order
         of the maturity of the installments of such interest, with interest (to
         the extent that such  interest has been  collected by the Trustee) upon
         the  overdue  installments  of interest at the rate borne by the Notes,
         such payments to be made ratably to the persons entitled thereto;

                  Third:  Subject to the  provisions  of Article IV, in case the
         principal  of  the   outstanding   Notes  shall  have  become  due,  by
         declaration  or  otherwise,  and be unpaid to the  payment of the whole
         amount then owing and unpaid upon the Notes for  principal and premium,
         if any,  and  interest,  with  interest  on the overdue  principal  and
         premium,  if any,  and (to the  extent  that  such  interest  has  been
         collected by the Trustee) upon overdue  installments of interest at the
         rate borne by the Notes;  and in case such monies shall be insufficient
         to pay in full the whole amounts so due and unpaid upon the Notes, then
         to the payment of such  principal  and  premium,  if any,  and interest
         without  preference or priority of principal and premium,  if any, over
         interest,  or of interest over principal and premium, if any, or of any
         installment of interest over any other  installment of interest,  or of
         any  Note  over  any  other  Note,  ratably  to the  aggregate  of such
         principal and premium, if any, and accrued and unpaid interest; and

                  Fourth:  Subject to the  provisions  of Article IV, to the 
         payment of the  remainder,  if any, to the Company or any other person
         lawfully entitled thereto.

         Section 7.4.  Proceedings  by  Noteholder.  No holder of any Note shall
have any right by virtue of or by availing of any provision of this Indenture to
institute  any suit,  action or  proceeding in equity or at law upon or under or
with respect to this Indenture,  or for the appointment of a receiver,  trustee,
liquidator,  custodian  or  other  similar  official,  or for any  other  remedy
hereunder, unless such holder previously shall have given to the Trustee written
notice

                                      -43-
<PAGE>

of an Event of Default and of the continuance thereof, as hereinbefore provided,
and unless also the holders of not less than 25 percent in  aggregate  principal
amount of the Notes then  outstanding  shall have made written  request upon the
Trustee to institute such action,  suit or proceeding in its own name as Trustee
hereunder and 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,  and the  Trustee  for sixty  (60) days  after its  receipt of such
notice,  request  and offer of  indemnity,  shall have  neglected  or refused to
institute any such action, suit or proceeding and no direction inconsistent with
such written  request  shall have been given to the Trustee  pursuant to Section
7.7; it being understood and intended,  and being expressly  covenanted,  by the
taker and  holder of every  Note  with  every  other  taker and  holder  and the
Trustee, that no one or more holders of Notes shall have any right in any manner
whatever by virtue of or by  availing  of any  provision  of this  Indenture  to
affect,  disturb or  prejudice  the rights of any other  holder of Notes,  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 Notes
(except as otherwise  provided  herein).  For the protection and  enforcement of
this Section 7.4, each and every Noteholder and the Trustee shall be entitled to
such relief as can be given either at law or in equity.

         Notwithstanding any other provision of this Indenture and any provision
of any Note,  the  right of any  holder of any Note to  receive  payment  of the
principal  of and premium,  if any,  and interest on such Note,  on or after the
respective  due dates  expressed  in such  Note,  or to  institute  suit for the
enforcement  of any such payment on or after such  respective  dates against the
Company shall not be impaired or affected without the consent of such holder.

         Anything   in   this   Indenture   or  the   Notes   to  the   contrary
notwithstanding,  the  holder of any Note,  without  the  consent  of either the
Trustee  or the  holder of any other  Note,  in his own  behalf  and for his own
benefit,  may enforce, and may institute and maintain any proceeding suitable to
enforce, his rights of conversion as provided herein.

         Section 7.5. Proceedings by Trustee. In case of an Event of Default the
Trustee may in its  discretion  proceed to protect and enforce the rights vested
in it by this Indenture by such appropriate  judicial proceedings as the Trustee
shall deem most  effectual to protect and enforce any of such rights,  either by
suit in equity or by action at law or by  proceeding in bankruptcy or otherwise,
whether for the specific  enforcement of any covenant or agreement  contained in
this Indenture or in aid of the exercise of any power granted in this Indenture,
or to enforce any other legal or  equitable  right vested in the Trustee by this
Indenture or by law.

         Section 7.6. Remedies Cumulative and Continuing . Except as provided in
Section 2.6, all powers and remedies given by this Article VII to the Trustee or
to the Noteholders  shall, to the extent permitted by law, be deemed  cumulative
and not  exclusive of any thereof or of any other powers and remedies  available
to the  Trustee  or the  holders  of  the  Notes,  by  judicial  proceedings  or
otherwise,  to enforce  the  performance  or  observance  of the  covenants  and
agreements contained in this Indenture,  and no delay or omission of the Trustee
or of any  holder

                                      -44-
<PAGE>

of any of the Notes to exercise any right or power  accruing upon any default or
Event of Default  occurring and  continuing  as aforesaid  shall impair any such
right or power,  or shall be construed to be a waiver of any such default or any
acquiescence therein; and, subject to the provisions of Section 7.4, every power
and  remedy  given  by  this  Article  VII or by law  to the  Trustee  or to the
Noteholders  may be exercised from time to time, and as often as shall be deemed
expedient, by the Trustee or by the Noteholders.

         Section  7.7.  Direction  of  Proceedings  and  Waiver of  Defaults  by
Majority  of  Noteholders  . The holders of a majority  in  aggregate  principal
amount  of the  Notes at the time  outstanding  determined  in  accordance  with
Section  9.4  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 (a) such
direction  shall not be in conflict with any rule of law or with this Indenture,
and (b) the Trustee may take any other action deemed proper by the Trustee which
is not inconsistent with such direction.  The holders of a majority in aggregate
principal amount of the Notes at the time  outstanding  determined in accordance
with Section 9.4 may on behalf of the holders of all of the Notes waive any past
default or Event of Default hereunder and its consequences  except (i) a default
in the  payment of interest or premium,  if any,  on, or the  principal  of, the
Notes,  (ii) a failure by the Company to convert  any Notes into  Common  Stock,
(iii) a default in the payment of  redemption  price  pursuant to Article III or
(iv) a default in respect of a covenant or provisions hereof which under Article
XI cannot be modified or amended without the consent of the holders of all Notes
then outstanding.  Upon any such waiver the Company, the Trustee and the holders
of the Notes shall be restored to their former  positions and rights  hereunder;
but no such waiver shall extend to any  subsequent  or other default or Event of
Default or impair any right consequent thereon. Whenever any default or Event of
Default  hereunder shall have been waived as permitted by this Section 7.7, said
default  or Event of  Default  shall  for all  purposes  of the  Notes  and this
Indenture  be deemed to have been  cured and to be not  continuing;  but no such
waiver shall extend to any  subsequent  or other  default or Event of Default or
impair any right consequent thereon.

         Section  7.8.  Statement by Officers as to Default.  The Company  shall
deliver to the  Trustee,  as soon as possible  and in any event within five days
after the Company  becomes aware of the occurrence of any Event of Default or an
event which, with notice or the lapse of time or both, would constitute an Event
of Default, an Officers'  Certificate setting forth the details of such Event of
Default  or default  and the  action  which the  Company  proposes  to take with
respect thereto.

         Section 7.9. Notice of Defaults . The Trustee shall, within ninety (90)
days  after  it has  knowledge  of the  occurrence  of a  default,  mail  to all
Noteholders,  as the names and  addresses of such  holders  appear upon the Note
register,  notice of all defaults  known to a Responsible  Officer,  unless such
defaults  shall have been cured or waived before the giving of such notice;  and
provided,  that,  except in the case of default in the payment of the  principal
of, or premium,  if any, or interest on any of the Notes,  the Trustee  shall be
protected  in  withholding  such notice if

                                      -45-
<PAGE>

and so long as a trust committee of directors and/or Responsible Officers of the
Trustee in good faith  determine  that the  withholding of such notice is in the
interests of the Noteholders.

         Section 7.10.  Undertaking to Pay Costs . All parties to this Indenture
agree, and each holder of any Note by such holder's  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 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  attorneys' 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 7.9 (to the
extent  permitted by law) shall not apply to any suit instituted by the Trustee,
to any suit  instituted by any Noteholder,  or group of Noteholders,  holding in
the aggregate more than ten percent in principal amount of the Notes at the time
outstanding determined in accordance with Section 9.4, or to any suit instituted
by any  Noteholder  for the  enforcement  of the payment of the  principal of or
premium,  if any, or interest on any Note on or after the due date  expressed in
such Note or to any suit for the enforcement of the right to convert any Note in
accordance with the provision of Article XV.

                                   ARTICLE VIII

                             CONCERNING THE TRUSTEE

         Section  8.1.  Duties and  Responsibilities  of Trustee . The  Trustee,
prior to the  occurrence  of an Event of  Default  and after  the  curing 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.

         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, expect that

                  (a)  prior to the  occurrence  of an Event of Default and 
after the curing or waiving of all 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 Trust  Indenture  Act, 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  and  the  Trust  Indenture  Act  against  the
                  Trustee; and

                                      -46-
<PAGE>
                           (2)  in  the   absence  of  bad  faith  and   willful
                  misconduct  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;  but, in the
                  case  of  any  such  certificates  or  opinions  which  by any
                  provisions hereof are specifically required to be furnished to
                  the Trustee,  the Trustee shall be under a duty to examine the
                  same  to  determine   whether  or  not  they  conform  to  the
                  requirements  of this  Indenture  (but  need  not  confirm  or
                  investigate the accuracy of mathematical calculations or other
                  facts stated therein);

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

            (c) the Trustee shall not be liable with respect to any action taken
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 Notes at the
time  outstanding  determined  as provided in Section 9.4  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; and

            (d)  whether  or not  therein  provided,  every  provision  of  this
Indenture  relating to the conduct or affecting  the  liability of, or affording
protection to, the Trustee shall be subject to the provisions of this Section.

         None of the provisions  contained in this  Indenture  shall require the
Trustee to expend or risk its own funds or otherwise  incur  personal  financial
liability in the  performance  of any of its duties or in the exercise of any of
its rights or powers,  if there is  reasonable  ground  for  believing  that the
repayment of such funds or adequate  indemnity against such risk or liability is
not reasonably assured to it.

         Section 8.2.  Reliance on  Documents,  Opinions,  Etc.  Except as 
 otherwise  provided in Section 8.1:

            (a) the Trustee may rely and shall be  protected  in acting upon any
resolution,   certificate,   statement,  instrument,  opinion,  report,  notice,
request,  consent,  order,  bond,  debenture,  note,  coupon  or other  paper or
document  believed  by it in good faith to be genuine and to have been signed or
presented by the proper party or parties;

            (b) any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by an Officers' Certificate (unless other
evidence  in  respect  thereof  be  herein  specifically  prescribed);  and  any
resolution  of the Board of Directors  may be evidenced

                                      -47-
<PAGE>

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 of its  selection  and any
advice or  Opinion  of  Counsel  shall be full and  complete  authorization  and
protection  in respect of any action  taken or omitted by it  hereunder  in good
faith and in accordance with such advice or Opinion of Counsel;

            (d) the Trustee  shall be under no obligation to exercise any of the
rights  or  powers  vested  in it by this  Indenture  at the  request,  order or
direction  of  any  of the  Noteholders  pursuant  to  the  provisions  of  this
Indenture,  unless such Noteholders shall have offered to the Trustee reasonable
security or indemnity  against the costs,  expenses and liabilities which may be
incurred therein or thereby;

            (e) the Trustee  shall not be bound to make any  investigation  into
the  facts  or  matters  stated  in  any  resolution,   certificate,  statement,
instrument,  opinion, report, notice, request, direction,  consent, order, bond,
debenture or other paper or document,  but the Trustee,  in its discretion,  may
make such further inquiry or investigation  into such facts or matters as it may
see fit,  and, if the Trustee  shall  determine to make such further  inquiry or
investigation,  it shall be entitled to examine the books,  records and premises
of the Company,  personally or by agent or attorney;  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  expenses or liability as a condition to so
proceeding;  the reasonable  expenses of every such examination shall be paid by
the  Company  or, if paid by the Trustee or any  predecessor  Trustee,  shall be
repaid by the Company upon demand;

            (f) 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 the  Trustee  shall  not be  responsible  for any  misconduct  or
negligence  on the part of any agent or attorney  appointed  by it with due care
hereunder;

            (g) the  Trustee  shall not be deemed to have notice of any Event of
Default unless a Responsible Officer of the Trustee has actual knowledge thereof
or  unless  written  notice of any  event  which is in fact  such a  default  is
received by the Trustee at the Corporate  Trust Office of the Trustee,  and such
notice references the Notes and this Indenture;

            (h) whenever in the  administration  of this  Indenture  the Trustee
shall deem it desirable that a matter be proved or established  prior to taking,
suffering or omitting any action  hereunder,  the Trustee (unless other evidence
be herein specifically prescribed) may, in the absence of bad faith on its part,
conclusively rely upon an Officers' Certificate; and

                                      -48-
<PAGE>

            (i) The Trustee,  any  authenticating  agent,  any paying agent, any
Note registrar or any other agent of the Company, in its individual or any other
capacity,  may become the owner or pledgee of the Notes, may otherwise deal with
the  Company  with  the  same  rights  it  would  have if it were  not  Trustee,
authenticating agent, paying agent, Note registrar or such other agent.

         Section  8.3.  No  Responsibility  for  Recitals,   Etc.  The  recitals
contained  herein  and in the Notes  (except  in the  Trustee's  certificate  of
authentication) 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
Notes.  The Trustee shall not be  accountable  for the use or application by the
Company of any Notes or the proceeds of any Notes authenticated and delivered by
the Trustee in conformity with the provisions of this Indenture.

         Section 8.4. Trustee, Paying Agents, Conversion Agents or Registrar May
Own  Notes.  The  Trustee,  any  paying  agent,  any  conversion  agent  or Note
registrar,  in its  individual  or any other  capacity,  may become the owner or
pledgee  of Notes  with the same  rights it would  have if it were not  Trustee,
paying agent, conversion agent or Note registrar.

         Section 8.5.  Monies to Be Held in Trust.  Subject to the provisions of
Section 13.4, all monies received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were received.
Money held by the Trustee in trust  hereunder 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 money  received by it hereunder  except as may be
agreed from time to time by the Company and the Trustee.

         Section  8.6.   Compensation  and  Expenses  of  Trustee.  The  Company
covenants  and agrees to pay to the Trustee  from time to time,  and the Trustee
shall be entitled to, such  compensation as shall be agreed to in writing by the
Company  and the  Trustee  for all  services  rendered  by it  hereunder  in any
capacity  (which  shall not be limited by any  provision of law in regard to the
compensation  of a trustee of an express  trust),  and the  Company  will pay or
reimburse   the  Trustee   upon  its  request  for  all   reasonable   expenses,
disbursements  and  advances  reasonably  incurred  or  made by the  Trustee  in
accordance  with  any  of  the  provisions  of  this  Indenture  (including  the
reasonable 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, willful misconduct, recklessness or
bad faith.  The Company also  covenants to indemnify the Trustee in any capacity
under this  Indenture  and its agents and any  authenticating  agent for, and to
hold them harmless  against,  any loss,  liability or expense,  including  taxes
(other  than taxes based upon,  measured by or  determined  by the income of the
Trustee) incurred without negligence,  willful misconduct,  recklessness, or bad
faith on the part of the Trustee or such agent or  authenticating  agent, as the
case  may be,  and  arising  out of or in  connection  with  the  acceptance  or
administration of this trust or in any other capacity  hereunder,  including the
costs and expenses of defending themselves against any claim of liability in the
premises. The obligations of the Company under this Section 8.6 to compensate or

                                      -49-
<PAGE>

indemnify  the  Trustee  and to pay  or  reimburse  the  Trustee  for  expenses,
disbursements and advances shall be secured by a lien prior to that of the Notes
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  Notes.  The
obligation of the Company under this Section shall survive the  satisfaction and
discharge of this Indenture.

         When the  Trustee  and its agents and any  authenticating  agent  incur
expenses  or render  services  after an Event of  Default  specified  in Section
7.1(d) or (e) occurs,  the  expenses and the  compensation  for the services are
intended  to  constitute  expenses  of  administration   under  any  bankruptcy,
insolvency or similar laws.

         The  provisions of this Section shall survive the  termination  of this
Indenture.

         Section  8.7.  Officers  Certificate  as Evidence . Except as otherwise
provided in Section 8.1,  whenever in the  administration  of the  provisions of
this Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or  established  prior to taking or omitting any action  hereunder,  such
matter  (unless  other  evidence  in  respect  thereof  be  herein  specifically
prescribed) may, in the absence of negligence, willful misconduct, recklessness,
or bad faith on the part of the Trustee, be deemed to be conclusively proved and
established by an Officers' Certificate delivered to the Trustee.

         Section 8.8.  Conflicting  Interests of Trustee . If the Trustee has or
shall acquire a conflicting  interest  within the meaning 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 Trustee
Indenture Act and this Indenture.

         Section  8.9.  Eligibility  of Trustee . There  shall at all times be a
Trustee hereunder which shall be a Person that is eligible pursuant to the Trust
Indenture Act to act as such and has a combined  capital and surplus of at least
$50,000,000.  If such person  publishes  reports of condition at least annually,
pursuant  to  law  or to  the  requirements  of  any  supervising  or  examining
authority,  then for the  purposes of this  Section,  the  combined  capital and
surplus of such person shall be deemed to be its combined capital and surplus as
set forth in its most recent  report of condition so  published.  If at any time
the Trustee shall cease to be eligible in accordance with the provisions of this
Section,  it  shall  resign  immediately  in the  manner  and  with  the  effect
hereinafter specified in this Article.

         Section 8.10.  Resignation or Removal of Trustee .

            (a) The Trustee may at any time resign by giving  written  notice of
such resignation to the Company and to the holders of Notes. 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

                                      -50-
<PAGE>

shall have been so  appointed  and have  accepted  appointment  thirty (30) days
after  the  mailing  of such  notice  of  resignation  to the  Noteholders,  the
resigning  Trustee may  petition  any court of  competent  jurisdiction  for the
appointment of a successor  trustee,  or any Noteholder who has been a bona fide
holder  of a Note or Notes  for at least  six (6)  months  may,  subject  to the
provisions  of  Section  7.9,  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 Section 
                  8.8 after written request therefor by the Company or by any
                  Noteholder who has been a bona fide holder of a Note or Notes
                  for at least six (6) months; or

                           (2)   the Trustee shall cease to be eligible in 
                  accordance with the provisions of Section 8.9 and shall fail
                  to resign after written  request  therefor by the Company or
                  by any such Noteholder; or

                           (3)   the  Trustee  shall  become  incapable  of
                  acting,  or shall be  adjudged a 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 the
                  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 7.9, any  Noteholder  who has been a bona fide holder of a
Note or Notes for at least six (6)  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.  If no
successor  trustee shall have been so appointed  and have  accepted  appointment
thirty (30) days after the mailing of such notice of removal to the Trustee, the
removed  Trustee  may  petition  any  court of  competent  jurisdiction  for the
appointment of a successor  trustee.  In either case,  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 Notes at the time outstanding may at any time remove the
Trustee and  nominate a successor  trustee  which shall be deemed  appointed  as
successor  trustee  unless  within ten (10) days after  notice to the Company of
such  nomination  the  Company  objects  thereto,  in which case the  Trustee so
removed or any  Noteholder,  upon the terms and  conditions  and otherwise as in
Section 8.10(a) provided,  may petition any court of competent  jurisdiction for
an appointment of a successor trustee.

            (d) Any  resignation or removal of the Trustee and  appointment of a
successor  trustee  pursuant to any of the provisions of this Section 8.10 shall
become  effective upon  acceptance of  appointment  by the successor  trustee as
provided in Section 8.11.

         Section 8.11.  Acceptance by Successor  Trustee . Any successor trustee
appointed as provided in Section 8.10 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 vested with all the rights,
powers, duties and obligations of its predecessor hereunder, with like effect as
if originally named as trustee herein; but, nevertheless, on the written request
of the Company or of the successor  trustee,  the trustee  ceasing to act shall,
upon  payment of any amounts then due it pursuant to the  provisions  of Section
8.6,  execute and deliver an instrument  transferring to such successor  trustee
all the rights and powers of the trustee so ceasing to act.  Upon request of any
such  successor  trustee,  the Company shall execute any and all  instruments in
writing for more fully and certainly vesting in and confirming to such successor
trustee  all  such  rights  and  powers.  Any  trustee  ceasing  to  act  shall,
nevertheless,  retain a lien upon all  property  and funds held or  collected by
such trustee as such,  except for funds held in trust for the benefit of holders
of  particular  Notes,  to  secure  any  amounts  then  due it  pursuant  to the
provisions of Section 8.6.

         No  successor  trustee  shall  accept  appointment  as provided in this
Section 8.11 unless at the time of such acceptance such successor  trustee shall
be  qualified  under the  provisions  of Section 8.8 and be  eligible  under the
provisions of Section 8.9.

         Upon  acceptance of appointment  by a successor  trustee as provided in
this Section 8.11, the Company (or the former trustee,  at the written direction
of the Company)  shall mail or cause to be mailed  notice of the  succession  of
such trustee  hereunder to the holders of Notes at their addresses as they shall
appear on the Note register. If the Company fails to mail such notice within ten
(10)  days  after  acceptance  of  appointment  by the  successor  trustee,  the
successor  trustee  shall  cause such  notice to be mailed at the expense of the
Company.

         Section 8.12.  Succession by Merger,  Etc . Any corporation  into which
the Trustee may be merged or converted or with which it may be consolidated,  or
any corporation resulting from any merger,  conversion or consolidation to which
the  Trustee  shall  be a  party,  or  any  corporation  succeeding  to  all  or
substantially all of the corporate trust business of the Trustee  (including any
trust  created  by  this  Indenture),  shall  be the  successor  to the  Trustee
hereunder without the execution or filing of any paper or any further act on the
part of any of the parties hereto, provided, that in the case of any corporation
succeeding to all or  substantially  all of the corporate  trust business of the
Trustee such corporation  shall be qualified under the provisions of Section 8.8
and eligible under the provisions of Section 8.9.

         In case at the time such  successor to the Trustee shall succeed to the
trusts created by this Indenture, any of the Notes shall have been authenticated
but not delivered,  any such successor

                                      -52-
<PAGE>

to the Trustee may adopt the  certificate of  authentication  of any predecessor
trustee or  authenticating  agent  appointed by such  predecessor  trustee,  and
deliver such Notes so  authenticated;  and in case at that time any of the Notes
shall  not  have  been  authenticated,  any  successor  to  the  Trustee  or  an
authenticating  agent appointed by such successor  trustee may authenticate such
Notes either in the name of any predecessor  trustee hereunder or in the name of
the successor  trustee;  and in all such cases such certificates  shall have the
full force which it is anywhere in the Notes or in this Indenture  provided that
the certificate of the Trustee shall have; provided,  however, that the right to
adopt  the  certificate  of  authentication   of  any  predecessor   Trustee  or
authenticate  Notes in the name of any  predecessor  Trustee shall apply only to
its successor or successors by merger, conversion or consolidation.

         Section 8.13. Limitation on Rights of Trustee as Creditor . If and when
the Trustee  shall be or become a creditor of the Company (or any other  obligor
upon the Notes),  the Trustee  shall be subject to the  provisions  of the Trust
Indenture Act regarding the collection of the claims against the Company (or any
such other obligor).

                           CONCERNING THE NOTEHOLDERS

         Section 9.1.  Action by  Noteholders . Whenever in this Indenture it is
provided  that the  holders of a specified  percentage  in  aggregate  principal
amount of the Notes 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 Noteholders
in person or by agent or proxy appointed in writing, or (b) by the record of the
holders of Notes  voting in favor  thereof at any  meeting of  Noteholders  duly
called  and held in  accordance  with the  provisions  of Article X, or (c) by a
combination  of such  instrument  or  instruments  and any such record of such a
meeting of Noteholders.  Whenever the Company or the Trustee solicits the taking
of any action by the holders of the Notes, the Company or the Trustee may fix in
advance of such solicitation,  a date as the record date for determining holders
entitled to take such  action.  The record  date shall be not more than  fifteen
(15) days prior to the date of commencement of solicitation of such action.

         Section  9.2.  Proof of  Execution  by  Noteholders  .  Subject  to the
provisions  of  Section  8.1,  8.2  and  10.5,  proof  of the  execution  of any
instrument  by a Noteholder or his agent or proxy shall be sufficient if made in
accordance  with such  reasonable  rules and regulations as may be prescribed by
the  Trustee or in such  manner as shall be  satisfactory  to the  Trustee.  The
holding  of  Notes  shall  be  proved  by the  registry  of such  Notes  or by a
certificate of the Note registrar.

         The record of any  Noteholders'  meeting  shall be proved in the manner
provided in Section 10.6.

                                      -53-

         Section 9.3. Who are Deemed Absolute Owners . The Company, the Trustee,
any paying  agent,  any  conversion  agent and any Note  registrar  may deem the
person in whose name such Note shall be registered upon the Note register to be,
and may treat him as, the absolute  owner of such Note (whether or not such Note
shall be overdue and  notwithstanding any notation of ownership or other writing
thereon) for the purpose of receiving  payment of or on account of the principal
of, premium,  if any, and interest on such Note, for conversion of such Note and
for all other  purposes;  and neither the Company nor the Trustee nor any paying
agent nor any conversion  agent nor any Note registrar  shall be affected by any
notice to the  contrary.  All such  payments  so made to any 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 monies  payable
upon any such Note.

         Section 9.4.  Company-Owned  Notes Disregarded . In determining whether
the holders of the requisite  aggregate principal amount of Notes have concurred
in any direction,  consent,  waiver or other action under this Indenture,  Notes
which  are owned by the  Company  or any  other  obligor  on the Notes 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 Notes shall
be  disregarded  and deemed not to be  outstanding  for the  purpose of any such
determination;  provided,  that for the  purposes  of  determining  whether  the
Trustee shall be protected in relying on any such direction,  consent, waiver or
other action only Notes which a Responsible  Officer knows are so owned shall be
so  disregarded.  Notes so owned  which  have been  pledged in good faith may be
regarded as  outstanding  for the  purposes  of this  Section 9.4 if the pledgee
shall  establish to the  satisfaction of the Trustee the pledgee's right to vote
such Notes and that the  pledgee is not the  Company,  any other  obligor on the
Notes or 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
the 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.  Upon request of
the  Trustee,  the Company  shall  furnish to the Trustee  promptly an Officers'
Certificate  listing and  identifying all Notes, if any, known by the Company to
be owned or held by or for the  account of any of the above  described  persons;
and,  subject to Section  8.1,  the  Trustee  shall be  entitled  to accept such
Officers'  Certificate as conclusive evidence of the facts therein set forth and
of the fact that all Notes not listed therein are  outstanding  for the purposes
of any such determination.

         Section 9.5. Revocation of Consents; Future Holders Bound . At any time
prior to (but not after) the  evidencing to the Trustee,  as provided in Section
9.1, of the taking of any action by the holders of the  percentage  in aggregate
principal  amount of the Notes  specified in this  Indenture in connection  with
such action,  any holder of a Note which is shown by the evidence to be included
in the Notes the holders of which have  consented  to such action may, by filing
written notice with the Trustee at its Corporate  Trust Office and upon proof of
holding as provided in Section 9.2,  revoke such action so far as concerns  such
Note. Except as aforesaid, any such action taken by the holder of any Note shall
be  conclusive  and  binding  upon such  holder and upon all future  holders and
owners  of such  Note  and of any  Notes  issued  in  exchange  or  substitution

                                      -54-

by written request setting forth in reasonable  detail the action proposed to be

agreements  and  stipulations  which may be therein  contained and to accept the
conveyance,  transfer and assignment of any property thereunder, but the Trustee
shall  not  be  obligated  to,  but  may  in  its  discretion,  enter  into  any
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

holders of any of the Notes at the time outstanding,  notwithstanding any of the
provisions of Section 11.2.

         Section 11.2.  Supplemental  Indentures  with Consent of  Noteholders .
With the  consent  (evidenced  as  provided in Article IX) of the holders of not
less than a  majority  in  aggregate  principal  amount of the Notes at the time
outstanding,  the Company,  when  authorized by the  resolutions of the Board of
Directors,  and the  Trustee may from time to time and at any time enter into an
indenture  or  indentures  supplemental  hereto  for the  purpose  of adding any
provisions to or changing in any manner or eliminating  any of the provisions of
this Indenture or any  supplemental  indenture or of modifying in any manner the
rights of the holders of the Notes; provided, however, that no such supplemental
indenture shall (i) extend the fixed maturity of any Note, or reduce the rate or
extend the time of payment of interest  thereon,  or reduce the principal amount
thereof or premium,  if any, thereon, or reduce any amount payable on redemption
or repurchase  thereof,  or impair the right of any Noteholder to institute suit
for the payment thereof,  or make the principal  thereof or interest or premium,
if any,  thereon payable in any coin or currency other than that provided in the
Notes,  or  modify  the  provisions  of  this  Indenture  with  respect  to  the
subordination  of the  Notes  in a  manner  adverse  to the  Noteholders  in any
material  respect,  or change the  obligation  of the Company to redeem any Note
upon the happening of a Fundamental  Change in a manner adverse to the holder of
Notes, or impair the right to convert the Notes into Common Stock subject to the
terms set forth  herein,  including  Section  15.6,  without  the consent of the
holder of each Note so  affected,  or (ii) reduce the  aforesaid  percentage  of
Notes,  the holders of which are  required  to consent to any such  supplemental
indenture, without the consent of the holders of all Notes then outstanding.

         Upon  the  request  of  the  Company,  accompanied  by a  copy  of  the
resolutions  of the Board of Directors  certified by its  Secretary or Assistant
Secretary authorizing the execution of any such supplemental indenture, and upon
the filing  with the  Trustee of  evidence  of the  consent  of  Noteholders  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 Noteholders under this
Section  11.2  to  approve  the  particular  form of any  proposed  supplemental
indenture,  but it  shall  be  sufficient  if such  consent  shall  approve  the
substance thereof.

         Section  11.3.  Effect  of  Supplemental  Indenture.  Any  supplemental
indenture  executed  pursuant to the  provisions of this Article XI shall comply
with the Trust  Indenture  Act, as then in effect;  provided,  that this Section
11.3  shall  not  require  such  supplemental  indenture  or the  Trustee  to be
qualified under the Trust Indenture Act prior to the time such  qualification is
in fact required under the terms of the Trust Indenture Act or the Indenture has
been  qualified  under the Trust  Indenture  Act,  nor shall it  constitute  any
admission or acknowledgment by any party to such supplemental indenture that any
such  qualification is required prior to the time such  qualification is in fact
required  under the terms of the Trust  Indenture  Act or the Indenture has been
qualified under the Trust Indenture Act. Upon the

                                      -59-
<PAGE>

execution  of any  supplemental  indenture  pursuant to the  provisions  of this
Article XI, this Indenture  shall be and be deemed to be modified and amended in
accordance   therewith  and  the  respective   rights,   limitation  of  rights,
obligations,  duties and  immunities  under this  Indenture of the Trustee,  the
Company and the holders of Notes 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 and
be deemed to be part of the terms and  conditions of this  Indenture for any and
all purposes.

         Section  11.4.  Notation on Notes.  Notes  authenticated  and delivered
after the execution of any supplemental  indenture pursuant to the provisions of
this  Article XI may bear a notation  in form  approved by the Trustee as to any
matter  provided  for in such  supplemental  indenture.  If the  Company  or the
Trustee shall so determine,  new Notes 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 may, at the Company's expense,  be
prepared  and  executed  by the  Company,  authenticated  by the  Trustee (or an
authenticating  agent duly  appointed by the Trustee  pursuant to Section 16.11)
and delivered in exchange for the Notes then outstanding, upon surrender of such
Notes then outstanding.

         Section 11.5.  Evidence of Compliance of  Supplemental  Indenture to Be
Furnished  Trustee . The Trustee,  subject to the provisions of Sections 8.1 and
8.2,  may  receive  an  Officers'  Certificate  and an  Opinion  of  counsel  as
conclusive  evidence that any supplemental  indenture  executed  pursuant hereto
complies with the requirements of this Article XI.

                                   ARTICLE XII

                CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE

         Section 12.1.  Company May Consolidate  Etc. on Certain Terms . Subject
to the provisions of Section 12.2, nothing contained in this Indenture or in any
of the Notes 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,
conveyance  or lease (or  successive  sales,  conveyances  or  leases) of all or
substantially  all of the  property  of the  Company,  to any other  corporation
(whether or not affiliated with the Company),  authorized to acquire and operate
the same and which  shall be  organized  under the laws of the United  States of
America, any state thereof or the District of Columbia;  provided, that upon any
such  consolidation,  merger,  sale,  conveyance or lease,  the due and punctual
payment of the  principal  of and  premium,  if any,  and interest on all of the
Notes,  according  to their  tenor,  and the due and  punctual  performance  and
observance  of all of the  covenants  and  conditions  of this  Indenture  to be
performed by the Company,  shall be expressly assumed, by supplemental indenture
satisfactory  in form to the Trustee,  executed and  delivered to the Trustee by
the  corporation (if other than the Company)  formed by such  consolidation,  or
into which the Company shall have been merged, or by the corporation

                                      -60-
<PAGE>

which shall be acquired or leased such property, and such supplemental indenture
shall provide for the applicable conversion rights set forth in Section 15.6.

         Section 12.2. Successor  Corporation to Be Substituted . In case of any
such consolidation, merger, sale, conveyance or lease and upon the assumption by
the successor corporation, by supplemental indenture,  executed and delivered to
the Trustee and  satisfactory  in form to the  Trustee,  of the due and punctual
payment of the  principal  of and  premium,  if any,  and interest on all of the
Notes and due and punctual performance of all of the covenants and conditions of
this Indenture to be performed by the Company,  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 Data  General  Corporation  any or all of the Notes  issuable  hereunder
which theretofore shall not have been signed by the Company and delivered to the
Trustee;  and,  upon the  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, or cause
to be  authenticated  and delivered,  any Notes which previously shall have been
signed  and  delivered  by the  officers  of the  Company  to  the  Trustee  for
authentication,  and any Notes which such successor corporation thereafter shall
cause to be signed and delivered to the Trustee for that purpose.  All the Notes
so issued shall in all respects  have the same legal rank and benefit under this
Indenture as the Notes  theretofore or thereafter  issued in accordance with the
terms of this  Indenture as though all of such Notes had been issued at the date
of the execution hereof. In the event of any such consolidation,  merger,  sale,
conveyance or lease,  the person named as the"Company" in the first paragraph of
this Indenture or any successor  which shall  thereafter have become such in the
manner prescribed in this Article XII may be dissolved,  wound up and liquidated
at any time thereafter and such person shall be released from its liabilities as
obligor and maker of the Notes and from its obligations under this Indenture.

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

         Section  12.3.  Opinion of Counsel to Be Given  Trustee.  The  Trustee,
subject to Sections 8.1 and 8.2, shall receive an Officers'  Certificate  and an
Opinion of Counsel as conclusive evidence that any such  consolidation,  merger,
sale,  conveyance or lease and any such assumption  complies with the provisions
of this Article XII.

                                   ARTICLE XIII

                     SATISFACTION AND DISCHARGE OF INDENTURE

         Section  13.1.  Discharge  of  Indenture . When (a) the  Company  shall
deliver to the  Trustee for  cancellation  all Notes  theretofore  authenticated
(other than any Notes which have

                                      -61-
<PAGE>

been destroyed, lost or stolen and in lieu of or in substitution for which other
Notes shall have been authenticated and delivered) and not theretofore canceled,
or (b) all the Notes not  theretofore  canceled or  delivered to the Trustee for
cancellation shall have become due and payable,  or are by their terms to become
due and payable  within one year or are to be called for  redemption  within one
year under arrangements  satisfactory to the Trustee for the giving of notice of
redemption,  and the Company  shall  deposit with the Trustee,  in trust,  funds
sufficient  to pay at maturity or upon  redemption  of all the Notes (other than
any Notes which shall have been mutilated, destroyed, lost or stolen and in lieu
of or in substitution  for which other Notes shall have been  authenticated  and
delivered)   not   theretofore   canceled  or   delivered  to  the  Trustee  for
cancellation,  including  principal and premium,  if any, and interest due or to
become due to such date of maturity or redemption  date, as the case may be, and
if in either case the Company  shall also pay or cause to be paid all other sums
payable  hereunder  by the  Company,  then this  Indenture  shall cease to be of
further effect (except as to (i) remaining  rights of  registration of transfer,
substitution  and exchange and  conversion  of Notes,  (ii) rights  hereunder of
Noteholders  to receive  payments  of  principal  of and  premium,  if any,  and
interest  on,  the  Notes  and the  other  rights,  duties  and  obligations  of
Noteholders,  as  beneficiaries  hereof with respect to the amounts,  if any, so
deposited with the Trustee and (iii) the rights,  obligations  and immunities of
the Trustee hereunder), and the Trustee, on demand of the Company accompanied by
an Officers'  Certificate  and an Opinion of Counsel as required by Section 16.5
and at the cost and expense of the Company,  shall  execute  proper  instruments
acknowledging  satisfaction  of and  discharging  this  Indenture;  the Company,
however,  hereby  agreeing  to  reimburse  the Trustee for any costs or expenses
thereafter reasonably and properly incurred by the Trustee and to compensate the
Trustee for any services  thereafter  reasonably  and  properly  rendered by the
Trustee in connection with this Indenture or the Notes.

         Section 13.2. Deposited Monies to Be Held in Trust by Trustee . Subject
to Section 13.4, all monies  deposited with the Trustee pursuant to Section 13.1
and not in  violation  of Article IV shall be held in trust for the sole benefit
of the  Noteholders  and not to be subject to the  subordination  provisions  of
Article  IV, and such  monies  shall be applied by the  Trustee to the  payment,
either directly or through any paying agent  (including the Company if acting as
its own paying agent), to the holders of the particular Notes for the payment or
redemption  of which such monies have been  deposited  with the Trustee,  of all
sums due and to become due thereon for  principal  and interest and premium,  if
any.

         Section 13.3.  Paying Agent to Repay Monies Held. Upon the satisfaction
and discharge of this Indenture, all monies then held by any paying agent of the
Notes (other than the Trustee) shall,  upon written  request of the Company,  be
repaid to it or paid to the Trustee,  and  thereupon  such paying agent shall be
released from all further liability with respect to such monies.

         Section 13.4.  Return of Unclaimed Monies . Subject to the requirements
of applicable law, any monies  deposited with or paid to the Trustee for payment
of the principal of,  premium,  if any, or interest on Notes and not applied but
remaining  unclaimed  by the  holders

                                      -62-
<PAGE>

of Notes for two years after the date upon which the principal of,  premium,  if
any, or interest  on such Notes,  as the case may be,  shall have become due and
payable,  shall be repaid  to the  Company  by the  Trustee  on  demand  and all
liability of the Trustee shall thereupon cease with respect to such monies;  and
the holder of any of the Notes shall thereafter look only to the Company for any
payment  which such  holder may be  entitled  to  collect  unless an  applicable
abandoned property law designates another Person.

         Section  13.5.  Reinstatement  . If the Trustee or the paying  agent is
unable to apply any money in accordance with Section 13.2 by reason of any order
or judgment of any court or  governmental  authority  enjoining,  restraining or
otherwise  prohibiting such  application,  the Company's  obligations under this
Indenture and the Notes shall be revived and reinstated as though no deposit had
occurred  pursuant to Section  13.1 until such time as the Trustee or the paying
agent is permitted  to apply all such money in  accordance  with  Section  13.2;
provided,  however,  that if the  Company  makes any  payment of  interest on or
principal  of any Note  following  the  reinstatement  of its  obligations,  the
Company  shall be  subrogated  to the  rights of the  holders  of such  Notes to
receive such payment from the money held by the Trustee or paying agent.

                    IMMUNITY OF INCORPORATORS, STOCKHOLDERS,
                             OFFICERS AND DIRECTORS

         Section  14.1.  Indenture and Notes Solely  Corporate  Obligations . No
recourse for the payment of the principal of or premium,  if any, or interest on
any Note, or for any claim based thereon or otherwise in respect thereof, and no
recourse under or upon any  obligation,  covenant or agreement of the Company in
this  Indenture or in any  supplemental  indenture or in any Note, or because of
the creation of any indebtedness  represented thereby,  shall be had against any
incorporator,  stockholder, employee, agent, officer, or director or subsidiary,
as  such,  past,  present  or  future,  of  the  Company  or  of  any  successor
corporation,   either   directly  or  through  the  Company  or  any   successor
corporation,  whether by virtue of any constitution,  statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise; it being expressly
understood that all such liability is hereby  expressly waived and released as a
condition of, and as a  consideration  for, the execution of this  Indenture and
the issue of the Notes.

                                   ARTICLE XV

                               CONVERSION OF NOTES

         Section 15.1.  Right to Convert . Subject to and upon  compliance  with
the provisions of this  Indenture,  the holder of any Note shall have the right,
at his or her option,  at any time

                                      -63-
<PAGE>

after  ninety (90) days  following  the latest date of original  issuance of the
Notes (without taking into account any over-allotment  option exercised pursuant
to Section 3 of the  Placement  Memorandum  dated May 15, 1997) and prior to the
close of business  on May 15, 2004  (except  that,  with  respect to any Note or
portion  of a Note  which  shall be called  for  redemption,  such  right  shall
terminate,  except as provided in Section  15.2 or Section  3.4, at the close of
business on the Business Day next  preceding  the date fixed for  redemption  of
such Note or portion of a Note unless the Company  shall  default in payment due
upon  redemption  thereof) to convert the principal  amount of any such Note, or
any portion of such  principal  amount  which is $1,000 or an integral  multiple
thereof,  into that  number of fully  paid and  non-assessable  shares of Common
Stock (as such  shares  shall then be  constituted)  obtained  by  dividing  the
principal  amount of the Note or portion  thereof  surrendered for conversion by
the  Conversion  Price in effect at such time, by surrender of the Note so to be
converted in whole or in part in the manner provided, together with any required
funds,  in Section  15.2.  A holder of Notes is not  entitled to any rights of a
holder of Common  Stock  until  such  holder has  converted  his Notes to Common
Stock,  and only to the extent such Notes are deemed to have been  converted  to
Common Stock under this Article XV.

         Section  15.2.  Exercise of  Conversion  Privilege;  Issuance of Common
Stock on  Conversion;  No  Adjustment  for  Interest or  Dividends . In order to
exercise the conversion privilege with respect to any Note in certificated form,
the holder of any such Note to be converted in whole or in part shall  surrender
such Note,  duly  endorsed,  at an office or agency  maintained  by the  Company
pursuant  to Section  5.2,  accompanied  by the funds,  if any,  required by the
penultimate  paragraph of this Section  15.2,  and shall give written  notice of
conversion  in the form  provided  on the Notes (or such other  notice  which is
acceptable  to the  Company) to the office or agency  that the holder  elects to
convert such Note or the portion thereof  specified in said notice.  Such notice
shall also state the name or names  (with  address  or  addresses)  in which the
certificate or  certificates  for shares of Common Stock which shall be issuable
on such conversion shall be issued,  and shall be accompanied by transfer taxes,
if required  pursuant to Section 15.7. Each such Note surrendered for conversion
shall,  unless the shares  issuable on  conversion  are to be issued in the same
name as the registration of such Note, be duly endorsed by, or be accompanied by
instruments  of transfer in form  satisfactory  to the Company duly executed by,
the holder or his duly authorized attorney.

         In order to  exercise  the  conversion  privilege  with  respect to any
interest in a Note in global  form,  the  beneficial  holder must  complete  the
appropriate  instruction  form  for  conversion  pursuant  to  the  Depository's
book-entry  conversion  program,  deliver by book-entry  delivery an interest in
such  Note  in  global  form,  furnish  appropriate  endorsements  and  transfer
documents if required by the Company or the Trustee or conversion agent, and pay
the funds,  if any,  required by this  Section  15.2 and any  transfer  taxes if
required pursuant to Section 15.7.

         As promptly as practicable  after  satisfaction of the requirements for
conversion  set forth above,  subject to  compliance  with any  restrictions  on
transfer if shares  issuable on

                                      -64-
<PAGE>

conversion  are to be issued in a name other than that of the  Noteholder (as if
such  transfer  were a transfer  of the Note or Notes (or  portion  thereof)  so
converted),  the  Company  shall  issue and shall  deliver to such holder at the
office or agency  maintained by the Company for such purpose pursuant to Section
5.2, a certificate or certificates for the number of full shares of Common Stock
issuable upon such conversion of such Note or portion thereof in accordance with
the  provisions of this Article and a check or cash in respect of any fractional
interest in respect of a share of Common Stock arising upon such conversion,  as
provided in Section 15.3. In case any Note of a denomination greater than $1,000
shall be  surrendered  for partial  conversion,  and subject to Section 2.3, the
Company  shall  execute and the Trustee  shall  authenticate  and deliver to the
holder of the Note so surrendered, without charge to him, a new Note or Notes in
authorized   denominations  in  an  aggregate  principal  amount  equal  to  the
unconverted portion of the surrendered Note.

         Each  conversion  shall be deemed to have been  effected as to any such
Note (or portion  thereof) on the date on which the requirements set forth above
in this Section 15.2 have been  satisfied as to such Note (or portion  thereof),
and the  person in whose  name 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 of  record of the  shares  represented  thereby;
provided,  however,  that any such surrender on any date when the stock transfer
books of the Company shall be closed shall  constitute  the person in whose name
the  certificates are to be issued as the record holder thereof for all purposes
on the next succeeding day on which such stock transfer books are open, but such
conversion  shall be at the  Conversion  Price in effect on the date upon  which
such Note shall be surrendered.

         Any Note or  portion  thereof  surrendered  for  conversion  during the
period from the close of business  on the record date for any  interest  payment
date to the close of business on the Business Day next  preceding  the following
interest payment date shall (unless such Note or portion thereof being converted
shall have been  called  for  redemption  during  the  period  from the close of
business on such record date to the close of business on the  Business  Day next
preceding the following interest payment date) be accompanied by payment, in New
York Clearing House funds or other funds acceptable to the Company, of an amount
equal to the interest  otherwise  payable on such  interest  payment date on the
principal amount being converted;  provided,  however, that no such payment need
be made if there shall exist at the time of  conversion a default in the payment
of interest on the Notes.  Except as provided  above in this  Section  15.2,  no
payment  or other  adjustment  shall be made for  interest  accrued  on any Note
converted or for dividends on any shares issued upon the conversion of such Note
as provided in this Article.

         Upon the  conversion  of an  interest  in a Note in  global  form,  the
Trustee, or the Custodian at the direction of the Trustee, shall make a notation
on such  Note  in  global  form  as to the  reduction  in the  principal  amount
represented thereby.

                                      -65-
<PAGE>

         Section  15.3.  Cash  Payments  in  Lieu  of  Fractional  Shares  .  No
fractional shares of Common Stock or scrip representing  fractional shares shall
be issued upon  conversion of Notes.  If more than one Note 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 Notes (or specified  portions thereof to the
extent permitted hereby) so surrendered.  If any fractional share of stock would
be issuable upon the conversion of any Note or Notes,  the Company shall make an
adjustment  and payment  therefor in cash at the current market value thereof to
the holder of Notes.  The current  market value of a share of Common Stock shall
be the Closing Price on the first Business Day immediately  preceding the day on
which  the  Notes  (or  specified  portions  thereof)  are  deemed  to have been
converted.

         Section  15.4.  Conversion  Price . The  conversion  price  shall be as
specified in the form of Note (herein called the "Conversion Price") attached as
Exhibit A hereto, subject to adjustment as provided in this Article XV.

         Section 15.5.  Adjustment of Conversion  Price.  The  Conversion  Price
shall be adjusted from time to time by the Company as follows:

            (a) In case the  Company  shall  hereafter  pay a dividend or make a
distribution to all holders of the outstanding  Common Stock in shares of Common
Stock,  the  Conversion  Price in effect at the  opening of business on the date
following  the date fixed for the  determination  of  stockholders  entitled  to
receive such dividend or other distribution shall be reduced by multiplying such
Conversion  Price by a fraction  of which the  numerator  shall be the number of
shares of Common  Stock  outstanding  at the close of business on the date fixed
for such  determination  and the denominator  shall be the sum of such number of
shares  and the total  number  of shares  constituting  such  dividend  or other
distribution,  such reduction to become effective  immediately after the opening
of  business  on the day  following  the day fixed for such  determination.  The
Company will not pay any dividend or make any  distribution  on shares of Common
Stock held in the treasury of the Company.  If any dividend or  distribution  of
the type described in this Section  15.5(a) is declared but not so paid or made,
the Conversion Price shall again be adjusted to the Conversion Price which would
then be in effect if such dividend or distribution had not been declared.

            (b) In case the  Company  shall  issue  rights  or  warrants  to all
holders of its  outstanding  shares of Common Stock entitling them (for a period
expiring within 45 days after the date fixed for  determination  of stockholders
entitled to receive such rights or warrants) to subscribe for or purchase shares
of Common  Stock at a price per share  less than the  Current  Market  Price (as
defined below) on the date fixed for  determination of stockholders  entitled to
receive such rights or warrants,  the Conversion Price shall be adjusted so that
the same shall equal the price determined by multiplying the Conversion Price in
effect  immediately  prior to the date fixed for  determination  of stockholders
entitled to receive such rights or warrants by a fraction of which the numerator
shall be the  number  of  shares of  Common  Stock  outstanding  at

                                      -66-
<PAGE>

the close of  business  on the date  fixed  for  determination  of  stockholders
entitled to receive such rights and 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,  and of which the denominator  shall be the number
of shares of Common Stock  outstanding  on the date fixed for  determination  of
stockholders  entitled to receive such rights and warrants plus the total number
of additional shares of Common Stock offered for subscription or purchase.  Such
adjustment shall be successively  made whenever any such rights and warrants are
issued, and shall become effective  immediately after the opening of business on
the day following the date fixed for  determination of stockholders  entitled to
receive such rights or  warrants.  To the extent that shares of Common Stock are
not delivered  after the  expiration of such rights or warrants,  the Conversion
Price shall be readjusted to the Conversion  Price which would then be in effect
had the adjustments  made upon the issuance of such rights or warrants been made
on the basis of delivery of only the number of shares of Common  Stock  actually
delivered.  In the event that such  rights or  warrants  are not so issued,  the
Conversion  Price shall again be adjusted to be the Conversion Price which would
then be in effect  if such date  fixed  for the  determination  of  stockholders
entitled to receive such rights or warrants had not been fixed.  In  determining
whether any rights or warrants  entitle the holders to subscribe for or purchase
shares  of  Common  Stock  at  less  than  such  Current  Market  Price,  and in
determining the aggregate  offering price of such shares of Common Stock,  there
shall be taken into account any  consideration  received by the Company for such
rights or warrants,  the value of such consideration,  if other than cash, to be
determined by the Board of Directors.

            (c) In case  outstanding  shares of Common Stock shall be subdivided
into a greater number of shares of Common Stock,  the Conversion Price in effect
at the  opening  of  business  on the day  following  the day  upon  which  such
subdivision becomes effective shall be proportionately  reduced, and conversely,
in case  outstanding  shares of Common  Stock shall be  combined  into a smaller
number of shares of Common Stock,  the Conversion Price in effect at the opening
of business on the day  following  the day upon which such  combination  becomes
effective shall be proportionately increased, such reduction or increase, as the
case may be, to become  effective  immediately  after the opening of business on
the day following the day upon which such  subdivision  or  combination  becomes
effective.

            (d) In case the Company shall, by dividend or otherwise,  distribute
to all holders of its Common Stock  shares of any class of capital  stock of the
Company  (other than any dividends or  distributions  to which  Section  15.5(a)
applies) or evidences of its indebtedness or assets (including  securities,  but
excluding any rights or warrants  referred to in Section 15.5(b),  and excluding
any dividend or distribution  (x) paid exclusively in cash or (y) referred to in
Section 15.5(a) (any of the foregoing hereinafter in this Section 15.5(d) called
the  "Securities")),  then,  in each such case  (unless  the  Company  elects to
reserve such Securities for  distribution to the Noteholders upon the conversion
of the Notes so that any such holder  converting  Notes will  receive  upon such
conversion,  in addition  to the shares of Common  Stock to which such holder is
entitled,  the amount and kind of such  Securities  which such holder would have
received if such holder had  converted  its Notes into Common Stock

                                      -67-

immediately  prior to the Record  Date (as  defined in Section  15.5(i) for such
distribution of the Securities)),  the Conversion Price shall be reduced so that
the same shall be equal to the price  determined by  multiplying  the Conversion
Price in effect  on the  Record  Date with  respect  to such  distribution  by a
fraction of which the numerator  shall be the Current  Market Price per share of
the Common Stock on such Record Date less the fair market  value (as  determined
by the  Board  of  Directors,  whose  determination  shall  be  conclusive,  and
described in a resolution  of the Board of  Directors) on the Record Date of the
portion of the Securities so distributed applicable to one share of Common Stock
and the  denominator  shall be the Current  Market Price per share of the Common
Stock,  such reduction to become effective  immediately  prior to the opening of
business on the day following such Record Date; provided, however, that from and
after the first  occurrence of a Section 11a(ii) Event, (as such term is defined
in the Renewed and  Restated  Rights  Agreement,  dated as of October 19,  1996,
between  the  Company  and The Bank of New York,  as in effect from time to time
(the "Rights Plan")),  the Conversion  Price with respect to Notes  beneficially
owned by

         (i) an Acquiring Person, an Adverse Person or an Associate or Affiliate
         of an Acquiring  Person or an Adverse Person (as each of such terms are
         defined in the Rights Plan),  (ii) a transferee of an Acquiring  Person
         or an  Adverse  Person  (or of any such  Associate  or  Affiliate)  who
         becomes a transferee  after the Acquiring  Person or the Adverse Person
         becomes  such,  or (iii) a  transferee  of an  Acquiring  Person  or an
         Adverse  Person (or of any such  Associate or Affiliate)  who becomes a
         transferee  prior to or concurrently  with the Acquiring  Person or the
         Adverse Person  becoming such and receives  rights to purchase Series A
         Junior  Participating  Stock,  par value $.01 per share, of the Company
         (the  "Rights")  pursuant to either (A) a transfer  (whether or not for
         consideration)  from the  Acquiring  Person  or the  Adverse  Person to
         holders of equity  interests in such Acquiring Person or Adverse Person
         or to any Person with whom the Acquiring  Person or the Adverse  Person
         has any continuing  agreement,  arrangement or understanding  regarding
         the  transferred  Rights or (B) a transfer which the Board of Directors
         of the  Company  has  determined  is  part of a  plan,  arrangement  or
         understanding which has as a primary purpose or effect the avoidance of
         the Rights Plan,

shall not be adjusted in accordance  with this paragraph (d) in connection  with
the distribution (or deemed distribution) of the Rights; and provided,  further,
that in the event the then fair market value (as so  determined)  of the portion
of the  Securities  so  distributed  applicable  to one share of Common Stock is
equal to or greater  than the Current  Market  Price of the Common  Stock on the
Record Date, in lieu of the foregoing  adjustment,  adequate  provision shall be
made so that each Noteholder shall have the right to receive upon conversion the
amount of Securities  such holder would have received had such holder  converted
each Note on the Record Date. In the event that such dividend or distribution is
not so paid or made,  the  Conversion  Price  shall  again be adjusted to be the
Conversion  Price which would then be in effect if such dividend or distribution
had not been  declared.  If the Board of  Directors  determines  the fair market
value of any  distribution  for purposes of this Section 15.5(d) by

                                      -68-
<PAGE>

reference to the actual or when issued  trading  market for any  securities,  it
must in doing so consider the prices in such market over the same period used in
computing the Current Market Price of the Common Stock.

         Rights or warrants  distributed by the Company to all holders of Common
Stock  entitling the holders  thereof to subscribe for or purchase shares of the
Company's capital stock (either initially or under certain circumstances), which
rights  or  warrants,  until  the  occurrence  of a  specified  event or  events
("Trigger  Event"):  (i) are deemed to be transferred with such shares of Common
Stock; (ii) are not exercisable;  and (iii) are also issued in respect of future
issuances  of Common  Stock,  shall be deemed not to have been  distributed  for
purposes of this Section 15.5 (and no adjustment to the  Conversion  Price under
this Section 15.5 will be required) until the occurrence of the earliest Trigger
Event,  whereupon  such  rights  and  warrants  shall  be  deemed  to have  been
distributed and an appropriate adjustment (if any is required) to the Conversion
Price shall be made under this  Section  15.5(d).  If any such right or warrant,
including any such existing rights or warrants  distributed prior to the date of
this Indenture,  are subject to events, upon the occurrence of which such rights
or warrants become  exercisable to purchase different  securities,  evidences of
indebtedness  or other assets,  then the date of the  occurrence of any and each
such event shall be deemed to be the date of  distribution  and record date with
respect  to new  rights or  warrants  with such  rights  (and a  termination  or
expiration  of the existing  rights or warrants  without  exercise by any of the
holders  thereof).  In  addition,  in the event of any  distribution  (or deemed
distribution) of rights or warrants, or any Trigger Event or other event (of the
type described in the preceding  sentence) with respect thereto that was counted
for purposes of calculating a distribution amount for which an adjustment to the
Conversion  Price under this Section 15.5 was made,  (1) in the case of any such
rights or warrants  which shall all have been  redeemed or  repurchased  without
exercise by any holders  thereof,  the Conversion Price shall be readjusted upon
such final  redemption  or  repurchase  to give effect to such  distribution  or
Trigger Event, as the case may be, as though it were a cash distribution,  equal
to the per share  redemption or repurchase price received by a holder or holders
of Common Stock with respect to such rights or warrants
 (assuming  such  holder had  retained  such  rights or  warrants),  made to all
holders of Common Stock as of the date of such redemption or repurchase, and (2)
in the  case of such  rights  or  warrants  which  shall  have  expired  or been
terminated  without exercise by any holders thereof,  the Conversion Price shall
be readjusted as if such rights and warrants had not been issued.

         For purposes of this Section 15.5(d) and Sections  15.5(a) and (b), any
dividend or  distribution  to which this Section 15.5(d) is applicable that also
includes  shares of Common  Stock,  or rights or  warrants to  subscribe  for or
purchase  shares of Common Stock (or both),  shall be deemed instead to be (1) a
dividend or distribution of the evidences of  indebtedness,  assets or shares of
capital  stock other than such shares of Common Stock or rights or warrants (and
any Conversion Price reduction  required by this Section 15.5(d) with respect to
such dividend or distribution shall then be made) immediately  followed by (2) a
dividend  or  distribution  of such  shares  of Common  Stock or such  rights or
warrants  (and any  further

                                      -69-
<PAGE>

Conversion Price reduction  required by Sections 15.5(a) and (b) with respect to
such dividend or distribution shall then be made), except (A) the Record Date of
such dividend or  distribution  shall be  substituted as "the date fixed for the
determination  of  stockholders  entitled  to  receive  such  dividend  or other
distribution" and "the date fixed for such determination"  within the meaning of
Sections  15.5(a)  and (b) and (B) any shares of Common  Stock  included in such
dividend  or  distribution  shall  not be  deemed  "outstanding  at the close of
business on the date fixed for such determination" within the meaning of Section
15.5(a).

                  (e) In case the  Company  shall,  by  dividend  or  otherwise,
distribute to all holders of its Common Stock cash  (excluding (x) any quarterly
cash dividend on the Common Stock to the extent the aggregate  cash dividend per
share of Common  Stock in any fiscal  quarter does not exceed the greater of (A)
the  amount  per  share of Common  Stock of the next  preceding  quarterly  cash
dividend  on the  Common  Stock to the  extent  that  such  preceding  quarterly
dividend did not require any adjustment of the Conversion Price pursuant to this
Section  15.5(e) (as adjusted to reflect  subdivisions  or  combinations  of the
Common  Stock),  and (B) 3.75% of the  arithmetic  average of the Closing  Price
(determined  as set forth in Section  15.5(h))  during the ten Trading  Days (as
defined in Section 15.5(h)) immediately prior to the date of declaration of such
dividend,   and  (y)  any  dividend  or  distribution  in  connection  with  the
liquidation,  dissolution  or winding up of the  Company,  whether  voluntary or
involuntary),  then, in such case, the Conversion Price shall be reduced so that
the same shall equal the price determined by multiplying the Conversion Price in
effect  immediately  prior to the close of  business  on such  Record  Date by a
fraction of which the numerator  shall be the Current Market Price of the Common
Stock  on the  Record  Date  less the  amount  of cash so  distributed  (and not
excluded  as provided  above)  applicable  to one share of Common  Stock and the
denominator  shall be such  Current  Market  Price  of the  Common  Stock,  such
reduction  to be effective  immediately  prior to the opening of business on the
day following the Record Date; provided,  however, that in the event the portion
of the cash so  distributed  applicable to one share of Common Stock is equal to
or greater than the Current Market Price of the Common Stock on the Record Date,
in lieu of the foregoing  adjustment,  adequate  provision shall be made so that
each  Noteholder  shall have the right to receive upon  conversion the amount of
cash such holder would have received had such holder  converted each Note on the
Record Date. In the event that such dividend or  distribution  is not so paid or
made, the Conversation  Price shall again be adjusted to be the Conversion Price
which  would then be in effect if such  dividend  or  distribution  had not been
declared.  If any adjustment is required to be made as set forth in this Section
15.5(e)  as a  result  of a  distribution  that is a  quarterly  dividend,  such
adjustment shall be based upon the amount by which such distribution exceeds the
amount of the quarterly cash dividend  permitted to be excluded pursuant hereto.
If an  adjustment  is required to be made as set forth in this  Section  15.5(e)
above as a result  of a  distribution  that is not a  quarterly  dividend,  such
adjustment shall be based upon the full amount of the distribution.

                  (f) In case a tender or exchange  offer made by the Company or
any  subsidiary  of the Company for all or any portion of the Common Stock shall
expire  and such

                                      -70-
<PAGE>

tender or exchange offer (as amended upon the expiration  thereof) shall require
the payment to stockholders of consideration  per share of Common Stock having a
fair market value (as determined by the Board of Directors,  whose determination
shall be conclusive  and described in a resolution of the Board of Directors) as
of the last  time (the  "Expiration  Time")  tenders  or  exchanges  may be made
pursuant to such tender or exchange  offer (as it may be amended)  that  exceeds
the Closing  Price of the Common  Stock on the Trading Day next  succeeding  the
Expiration  Time, the  Conversion  Price shall be reduced so that the same shall
equal  the  price  determined  by  multiplying  the  Conversion  Price in effect
immediately  prior to the  Expiration  Time by a fraction of which the numerator
shall be the  number  of  shares  of Common  Stock  outstanding  (including  any
tendered or exchanged  shares) on the Expiration  Time multiplied by the Current
Market  Price  of the  Common  Stock on the  Trading  Day  next  succeeding  the
Expiration  Time and the  denominator  shall  be the sum of (x) the fair  market
value  (determined  as  aforesaid)  of the  aggregate  consideration  payable to
shareholders  based on the acceptance (up to any maximum  specified in the terms
of the tender or exchange offer) of all shares validly tendered or exchanged and
not withdrawn as of the  Expiration  Time (the shares deemed so accepted,  up to
any such  maximum,  being  referred to as the  "Purchased  Shares")  and (y) the
product of the number of shares of Common Stock  outstanding (less any Purchased
Shares) on the Expiration  Time and the Closing Price of the Common Stock on the
Trading Day next  succeeding  the  Expiration  Time,  such  reduction  to become
effective  immediately prior to the opening of business on the day following the
Expiration  Time. In the event that the Company is obligated to purchase  shares
pursuant to any such tender or exchange  offer,  but the Company is  permanently
prevented  by  applicable  law from  effecting  any such  purchases  or all such
purchases are rescinded,  the Conversion Price shall again be adjusted to be the
Conversion  Price which would then be in effect if such tender or exchange offer
had not been made.

                  (g) In case of a tender  or  exchange  offer  made by a person
other than the  Company or any  Subsidiary  for an amount  which  increases  the
offeror's  ownership  of  Common  Stock  to more  than 25% of the  Common  Stock
outstanding  and shall involve the payment by such person of  consideration  per
share of Common Stock having a fair market value (as  determined by the Board of
Directors,   whose  determination  shall  be  conclusive,  and  described  in  a
resolution of the Board of Directors) at the last time (the  "Expiration  Time")
tenders or exchanges may be made  pursuant to such tender or exchange  offer (as
it shall have been  amended)  that exceeds the Closing Price of the Common Stock
on the Trading Day next succeeding the Expiration  Time, and in which, as of the
Expiration  Time the Board of  Directors  is not  recommending  rejection of the
offer,  the  Conversion  Price shall be reduced so that the same shall equal the
price determined by multiplying the Conversion Price in effect immediately prior
to the Expiration  Time by a fraction of which the numerator shall be the number
of shares of Common  Stock  outstanding  (including  any  tendered or  exchanged
shares) on the  Expiration  Time  multiplied  by the Closing Price of the Common
Stock on the Trading Day next succeeding the Expiration Time and the denominator
shall be the sum of (x) the fair market value  (determined  as aforesaid) of the
aggregate  consideration  payable to stockholders based on the acceptance (up to
any  maximum  specified  in the terms of the  tender or  exchange

                                      -71-
<PAGE>

offer) of all shares  validly  tendered or exchanged and not withdrawn as of the
Expiration  Time (the shares deemed so accepted,  up to any such maximum,  being
referred  to as the  "Purchased  Shares")  and (y) the  product of the number of
shares of Common Stock outstanding (less any Purchased Shares) on the Expiration
Time  and the  Closing  Price  of the  Common  Stock  on the  Trading  Day  next
succeeding the Expiration Time, such reduction to become  effective  immediately
prior to the opening of business on the day  following the  Expiration  Time. In
the event that such person is obligated to purchase  shares pursuant to any such
tender or exchange offer, but such person is permanently prevented by applicable
law from effecting any such  purchases or all such purchases are rescinded,  the
Conversion  Price shall again be adjusted to be the Conversion Price which would
then be in  effect  if  such  tender  or  exchange  offer  had  not  been  made.
Notwithstanding the foregoing,  the adjustment described in this Section 15.5(g)
shall not be made if, as of the  Expiration  Time,  the offering  documents with
respect  to such  offer  disclose a plan or  intention  to cause the  Company to
engage in any transaction described in Article XII.

                  (h)      For purposes of this Section 15.5, the following 
terms shall have the meaning indicated:

                           (1) "Closing Price" with respect to any securities on
                  any day shall mean the closing sale price  regular way on such
                  day or, in case no such  sale  takes  place on such  day,  the
                  average of the reported closing bid and asked prices,  regular
                  way, in each case on the New York Stock Exchange,  or, if such
                  security  is  not  listed  or  admitted  to  trading  on  such
                  Exchange,  on the  principal  national  security  exchange  or
                  quotation system on which such security is quoted or listed or
                  admitted to  trading,  or, if not quoted or listed or admitted
                  to trading on any  national  securities  exchange or quotation
                  system,  the average of the  closing  bid and asked  prices of
                  such  security  on the  over-the-counter  market on the day in
                  question  as  reported  by  the  National   Quotation   Bureau
                  Incorporated,   or  a  similar  generally  accepted  reporting
                  service,  if not so available,  in such manner as furnished by
                  any New York Stock Exchange  member firm selected from time to
                  time by the Board of Directors  for that  purpose,  or a price
                  determined  in good faith by the Board of Directors or, to the
                  extent   permitted  by  applicable   law,  a  duly  authorized
                  committee thereof, whose determination shall be conclusive.

                           (2) "Current  Market Price" shall mean the average of
                  the daily Closing Prices per share of Common Stock for the ten
                  (10) consecutive Trading Days immediately prior to the date in
                  question;  provided,  however,  that (1) if the "ex"  date (as
                  hereinafter defined) for any event (other than the issuance or
                  distribution or Fundamental Change requiring such computation)
                  that requires an adjustment to the  Conversion  Price pursuant
                  to Section  15.5(a),  (b),  (c),  (d),  (e), (f) or (g) occurs
                  during such ten  consecutive  Trading Days,  the Closing Price
                  for each  Trading  Day prior to the "ex"  date for such  other
                  event shall be

                                      -72-
<PAGE>

                  adjusted  by  multiplying  such  Closing  Price  by  the  same
                  fraction  by which the  Conversion  Price is so required to be
                  adjusted as a result of such other event, (2) if the "ex" date
                  for any  event  (other  than  the  issuance,  distribution  or
                  Fundamental  Change requiring such  computation) that required
                  an  adjustment  to the  Conversion  Price  pursuant to Section
                  15.5(a), (b), (c), (d), (e), (f) or (g) occurs on or after the
                  "ex" date for the  issuance  or  distribution  requiring  such
                  computation  and  prior to the day in  question,  the  Closing
                  Price for each Trading Day on and after the "ex" date for such
                  other  event shall be adjusted  by  multiplying  such  Closing
                  Price  by  the   reciprocal  of  the  fraction  by  which  the
                  Conversion  Price is so required to be adjusted as a result of
                  such other event,  and (3) if the "ex" date for the  issuance,
                  distribution or Fundamental  Change requiring such computation
                  is prior to the day in question, after taking into account any
                  adjustment  required  pursuant  to  clause  (1) or (2) of this
                  proviso,  the Closing  Price for each  Trading Day on or after
                  such "ex" date shall be adjusted by adding  thereto the amount
                  of any cash and the fair market  value (as  determined  by the
                  Board of Directors  or, to the extent  permitted by applicable
                  law,  a  duly  authorized   committee   thereof  in  a  manner
                  consistent with any  determination  of such value for purposes
                  of Section 15.5(d),  (f) or (g) whose  determination  shall be
                  conclusive  and  described  in a  resolution  of the  Board of
                  Directors or such duly authorized  committee  thereof,  as the
                  case  may be) of the  evidences  of  indebtedness,  shares  of
                  capital  stock or assets being  distributed  applicable to one
                  share of Common  Stock as of the close of  business on the day
                  before such "ex" date. For purposes of any  computation  under
                  Section 15.5(f) or (g), the Current Market Price of the Common
                  Stock on any date  shall be  deemed to be the  average  of the
                  daily  Closing  Prices per share of Common  Stock for such day
                  and the next two succeeding Trading Days;  provided,  however,
                  that if the "ex" date for any event  (other than the tender or
                  exchange offer  requiring such  computation)  that requires an
                  adjustment  to  the  Conversion   Price  pursuant  to  Section
                  15.5(a), (b), (c), (d), (e), (f) or (g) occurs on or after the
                  Expiration  Time for the tender or  exchange  offer  requiring
                  such computation and prior to the day in question, the Closing
                  Price for each Trading Day on and after the "ex" date for such
                  other  event shall be adjusted  by  multiplying  such  Closing
                  Price  by  the   reciprocal  of  the  fraction  by  which  the
                  Conversion  Price is so required to be adjusted as a result of
                  such other  event.  For purposes of this  paragraph,  the term
                  "ex"  date,  (1) when used with  respect  to any  issuance  or
                  distribution,  means the first date on which the Common  Stock
                  trades regular way on the relevant exchange or in the relevant
                  market from which the Closing  Price was obtained  without the
                  right to receive such issuance or distribution,  (2) when used
                  with respect to any  subdivision  or  combination of shares of
                  Common  Stock,  means the first date on which the Common Stock
                  trades  regular way on such  exchange or in such market  after
                  the time at which  such  subdivision  or  combination  becomes
                  effective,  and (3) when used with  respect  to any  tender or
                  exchange  offer means the first date on which

                                      -73-
<PAGE>

                  the Common  Stock  trades  regular way on such  exchange or in
                  such market after the Expiration Time of such offer.

                           (3) "fair market value" shall mean the amount which a
                  willing  buyer would pay a willing  seller in an arm's  length
                  transaction.

                           (4) "Record  Date" shall  mean,  with  respect to any
                  dividend,  distribution or other transaction or event in which
                  the  holders of Common  Stock  have the right to  receive  any
                  cash,  securities  or other  property  or in which the  Common
                  Stock (or  other  applicable  security)  is  exchanged  for or
                  converted into any  combination  of cash,  securities or other
                  property,  the date fixed for  determination  of  shareholders
                  entitled to receive such cash,  securities  or other  property
                  (whether  such date is fixed by the Board of  Directors  or by
                  statute, contract or otherwise).

                           (5)  "Trading  Day" shall mean (x) if the  applicable
                  security  is listed or  admitted  for  trading on the New York
                  Stock Exchange or another national security exchange, a day on
                  which the New York Stock Exchange or another national security
                  exchange  is  open  for  business  or (y)  if  the  applicable
                  security  is quoted on the Nasdaq  National  Market,  a day on
                  which  trades may be made on thereon or (z) if the  applicable
                  security is not so listed, admitted for trading or quoted, any
                  day other than a Saturday or Sunday or a day on which  banking
                  institutions  in the  State  of New  York  are  authorized  or
                  obligated by law or executive order to close.

         (i) The Company may make such  reductions in the Conversion  Price,  in
addition to those  required by Sections 15.5 (a), (b), (c), (d), (e), (f) or (g)
as the Board of  Directors  considers  to be  advisable to avoid or diminish any
income  tax to  holders  of  Common  Stock or rights to  purchase  Common  Stock
resulting  from any  dividend  or  distribution  of stock (or  rights to acquire
stock) or from any event treated as such for income tax purposes.

         To the extent  permitted  by  applicable  law, the Company from time to
time may reduce the Conversion Price by any amount for any period of time if the
period is at least twenty (20) days,  the  reduction is  irrevocable  during the
period  and the Board of  Directors  shall have made a  determination  that such
reduction  would be in the best  interests of the Company,  which  determination
shall be conclusive.  Whenever the Conversion  Price is reduced  pursuant to the
preceding  sentence,  the Company shall mail to holders of record of the Notes a
notice of the reduction at least fifteen (15) days prior to the date the reduced
Conversion  Price  takes  effect,  and  such  notice  shall  state  the  reduced
Conversion Price and the period during which it will be in effect.

                  (j) No  adjustment in the  Conversion  Price shall be required
unless such  adjustment  would require an increase or decrease of at least 1% in
such price;  provided,

                                      -74-
<PAGE>

however,  that any  adjustments  which by reason of this Section 15.5(j) are not
required  to be made shall be  carried  forward  and taken  into  account in any
subsequent  adjustment.  All calculations under this Article XV shall be made by
the  Company  and  shall  be made to the  nearest  cent  or to the  nearest  one
hundredth of a share,  as the case may be. No adjustment need be made for rights
to  purchase  Common  Stock  pursuant  to a  Company  plan for  reinvestment  of
dividends or interest.  To the extent the Notes  become  convertible  into cash,
assets,  property or securities  (other than capital  stock of the Company),  no
adjustment  need be made  thereafter  as to the cash,  assets,  property or such
securities. Interest will not accrue on the cash.

                  (k)  Whenever  the  Conversion  Price is  adjusted  as  herein
provided,  the Company shall  promptly file with the Trustee and any  conversion
agent  other  than the  Trustee  an  Officers'  Certificate  setting  forth  the
Conversion  Price after such  adjustment and setting forth a brief  statement of
the  facts   requiring  such   adjustment.   Promptly  after  delivery  of  such
certificate,  the  Company  shall  prepare  a notice of such  adjustment  of the
Conversion  Price  setting forth the adjusted  Conversion  Price and the date on
which each  adjustment  becomes  effective  and shall  mail such  notice of such
adjustment  of the  Conversion  Price  to the  holder  of each  Note at his last
address  appearing  on the Note  register  provided  for in Section  2.5 of this
Indenture,  within twenty (20) days after execution thereof.  Failure to deliver
such notice shall not affect the legality or validity of any such adjustment.

                  (l) In any case in which this  Section 15.5  provides  that an
adjustment shall become effective  immediately after a record date for an event,
the  Company  may defer  until the  occurrence  of such event (i) issuing to the
holder of any Note converted after such record date and before the occurrence of
such event the additional  shares of Common Stock issuable upon such  conversion
by reason of the  adjustment  required  by such  event over and above the Common
Stock issuable upon such conversion  before giving effect to such adjustment and
(ii) paying to such holder any amount in cash in lieu of any  fraction  pursuant
to Section 15.3.

                  (m) For purposes of this Section 15.5, the number of shares of
Common  Stock at any time  outstanding  shall  not  include  shares  held in the
treasury of the Company but shall  include  shares  issuable in respect of scrip
certificates  issued in lieu of fractions of shares of Common Stock. The Company
will not pay any  dividend or make any  distribution  on shares of Common  Stock
held in the treasury of the Company.

         Section 15.16.  Effect of  Reclassification,  Consolidation,  Merger or
Sale . If any of the following events occur, namely (i) any  reclassification or
change of the  outstanding  shares of Common Stock (other than a subdivision  or
combination to which Section 15.5(c) applies), (ii) any consolidation, merger or
combination of the Company with another corporation as a result of which holders
of Common Stock shall be entitled to receive stock, securities or other property
or assets (including cash) with respect to or in exchange for such Common Stock,
or (iii) any sale or conveyance of the  properties and assets of the Company as,
or substantially  as, an entirety to any other  corporation as a result of which
holders of Common Stock shall be

                                      -75-
<PAGE>

entitled to receive  stock,  securities or other  property or assets  (including
cash) with respect to or in exchange for such Common Stock,  then the Company or
the successor or purchasing corporation,  as the case may be, shall execute with
the  Trustee  a  supplemental  indenture  (which  shall  comply  with the  Trust
Indenture  Act as in  force  at the  date  of  execution  of  such  supplemental
indenture)  providing  that such  Note  shall be  convertible  into the kind and
amount of shares of stock and other securities or property or assets  (including
cash)  receivable upon such  reclassification,  change,  consolidation,  merger,
combination,  sale or  conveyance  by a holder  of a number  of shares of Common
Stock issuable upon  conversion of such Notes  (assuming,  for such purposes,  a
sufficient  number of authorized shares of Common Stock available to convert all
such Notes) immediately prior to such reclassification,  change,  consolidation,
merger, combination, sale or conveyance assuming such holder of Common Stock did
not  exercise  his  rights  of  election,  if any,  as to the kind or  amount of
securities,  cash or other property receivable upon such consolidation,  merger,
statutory exchange, sale or conveyance (provided, that, if the kind or amount of
securities,  cash or other property receivable upon such consolidation,  merger,
statutory exchange,  sale or conveyance is not the same for each share of Common
Stock in respect of which such rights of election  shall not have been exercised
("nonelecting-share")),  then for the purposes of this Section 15.6 the kind and
amount of securities, cash or other property receivable upon such consolidation,
merger, statutory exchange, sale or conveyance for each non-electing share shall
be deemed to be the kind and amount so  receivable  per share by a plurality  of
the  non-electing   shares.  Such  supplemental   indenture  shall  provide  for
adjustments  which shall be as nearly  equivalent as may be  practicable  to the
adjustments provided for in this Article.

        The Company  shall cause notice of the  execution  of such  supplemental
indenture to be mailed to each holder of Notes, at his address  appearing on the
Note register provided for in Section 2.5 of this Indenture,  within twenty (20)
days after  execution  thereof.  Failure to deliver such notice shall not affect
the legality or validity of such supplemental indenture.

         The  above   provisions  of  this  Section  shall  similarly  apply  to
successive reclassifications,  changes,  consolidations,  mergers, combinations,
sales and conveyances.

         If this Section 15.6 applies to any event or  occurrence,  Section 15.5
shall not apply.

         Section 15.17.  Taxes on Shares Issued. The issue of stock certificates
on  conversions  of  Notes  shall  be  made  without  charge  to the  converting
Noteholder for any tax in respect of the issue  thereof.  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 any name other than that
of the holder of any Note  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 issue thereof shall have paid to the Company the amount
of such tax or shall have  established to the  satisfaction  of the Company that
such tax has been paid.

                                      -76-
<PAGE>

         Section  15.18.  Reservation  of  Shares;  Shares  to  Be  Fully  Paid,
Compliance with Governmental Requirements; Listing of Common Stock . The Company
shall provide,  free from preemptive  rights, out of its authorized but unissued
shares or shares held in treasury,  sufficient shares of Common Stock to provide
for the  conversion  of the Notes from time to time as such Notes are  presented
for conversion.

         Before taking any action which would cause an  adjustment  reducing the
Conversion Price below the then par value, if any, of the shares of Common Stock
issuable  upon  conversion  of the Notes,  the Company  will take all  corporate
action which may, in the opinion of its counsel,  be necessary in order that the
Company  may  validly and  legally  issue  shares of such  Common  Stock at such
adjusted Conversion Price.

         The  Company  covenants  that all shares of Common  Stock  which may be
issued upon conversion of Notes will upon issue be fully paid and non-assessable
by the Company and free from all taxes,  liens and charges  with  respect to the
issue thereof.

         The Company covenants that if any shares of Common Stock to be provided
for the purpose of conversion of Notes hereunder  require  registration  with or
approval  of any  governmental  authority  under any federal or state law before
such shares may be validly  issued  upon  conversion,  the Company  will in good
faith and as expeditiously as possible  endeavor to secure such  registration or
approval, as the case may be.

         The  Company  further  covenants  that if at any time the Common  Stock
shall be listed on the New York Stock Exchange or any other national  securities
exchange or automated  quotation  system the Company  will,  if permitted by the
rules of such exchange or automated  quotation system,  list and keep listed, so
long as the  Common  Stock  shall be so listed  on such  exchange  or  automated
quotation  system,  all Common  Stock  issuable  upon  conversion  of the Notes;
provided,  however, that if rules of such exchange or automated quotation system
permit the  Company to defer the  listing of such  Common  Stock until the first
conversion of the Notes into Common Stock in accordance  with the  provisions of
this  Indenture,  the Company  covenants to list such Common Stock issuable upon
conversion of the Notes in accordance with the  requirements of such exchange or
automated quotation system at such time.

         Section  15.19.  Responsibility  of Trustee.  The Trustee and any other
conversion  agent shall not at any time be under any duty or  responsibility  to
any holder of Notes to  determine  whether any facts exist which may require any
adjustment of the Conversion  Price,  or with respect to the nature or extent or
calculation  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.  The  Trustee  and any  other  conversion  agent  shall not 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,  which may at any time
be issued or delivered  upon the conversion of any Note; and the Trustee and any
other conversion agent make no representations with respect thereto.  Subject to
the  provisions  of Section 8.1,  neither the

                                      -77-
<PAGE>

Trustee nor any  conversion  agent shall be  responsible  for any failure of the
Company  to issue,  transfer  or  deliver  any  shares of Common  Stock or stock
certificates  or other  securities or property or cash upon the surrender of any
Note  for the  purpose  of  conversion  or to  comply  with  any of the  duties,
responsibilities or covenants of the Company contained in this Article.  Without
limiting the generality of the foregoing, neither the Trustee nor any conversion
agent shall be under any  responsibility  to determine  the  correctness  of any
provisions  contained in any  supplemental  indenture  entered into  pursuant to
Section  15.6  relating  either  to the kind or  amount  of  shares  of stock or
securities  or property  (including  cash)  receivable by  Noteholders  upon the
conversion of their Notes after any event referred to in such Section 15.6 or to
any adjustment to be made with respect  thereto,  but, subject to the provisions
of Section 8.1, may accept as conclusive evidence of the correctness of any such
provisions,  and shall be protected in relying upon,  the Officers'  Certificate
(which the Company  shall be  obligated  to file with the  Trustee  prior to the
execution of any such supplemental indenture) with respect thereto.

         Section 15.10.  Notice to Holders Prior to Certain Actions .  In case:

         (a) the Company shall declare a dividend (or any other distribution) on
its Common  Stock  that would  require an  adjustment  in the  Conversion  Price
pursuant to Section 15.5; or

         (b) the Company shall authorize the granting to the holders of its 
Common Stock of rights or warrants to subscribe for or purchase any share of any
class or any other rights or warrants; or

         (c) of any  reclassification  or  reorganization of the Common Stock of
the Company (other than a subdivision or combination of its  outstanding  Common
Stock,  or a change in par value,  or from par value to no par value, or from no
par value to par value),  or of any consolidation or merger to which the Company
is a party  and  for  which  approval  of any  shareholders  of the  Company  is
required,  or of the sale or transfer of all or substantially  all of the assets
of the Company; or

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

the  Company  shall  cause to be filed with the Trustee and to be mailed to each
holder of Notes at his address  appearing on the Note  register  provided for in
Section 2.5 of this Indenture, as promptly as possible but in any event at least
fifteen (15) days prior to the applicable date hereinafter  specified,  a notice
stating  (x) the date on which a record is to be taken for the  purpose  of such
dividend,  distribution  or  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 or rights are to be determined,  or (y) the date
on  which  such   reclassification,   consolidation,   merger,  sale,  transfer,
dissolution, liquidation or winding-up is expected to become effective or occur,
and the date as of which it is expected  that  holders of Common Stock of record
shall be  entitled  to  exchange  their  Common  Stock for  securities  or other

                                      -78-
<PAGE>

property deliverable upon such  reclassification,  consolidation,  merger, sale,
transfer,  dissolution,  liquidation or winding-up. Failure to give such notice,
or any defect  therein,  shall not  affect  the  legality  or  validity  of such
dividend, distribution, reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding-up.

                    6% CONVERTIBLE SUBORDINATED NOTE DUE 2004


         This Note is one of a duly  authorized  issue of Notes of the  Company,
designated as its 6% Convertible  Subordinated Notes due 2004 (herein called the
"Notes"),  limited to the aggregate  principal amount of $212,750,000 all issued
or to be issued  under and  pursuant  to an  indenture  dated as of May 21, 1997
(herein called the  "Indenture"),  between the Company and The Bank of New York,
as trustee (herein called the "Trustee"),  to which Indenture and all indentures
supplemental  thereto  reference is hereby made for a description of the rights,
limitations  of rights,  obligations,  duties and  immunities  thereunder of the
Trustee, the Company and the holders of the Notes.

         In case an Event of Default,  as defined in the  Indenture,  shall have
occurred and be continuing,  the principal of and accrued  interest on all Notes
may be declared, and upon said declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Indenture.

         The  Indenture  contains  provisions  permitting  the  Company  and the
Trustee,  with the  consent  of the  holders  of not  less  than a  majority  in
aggregate principal amount of the Notes at the time outstanding, evidenced as in
the Indenture provided, to execute supplemental indentures adding any provisions
to or  changing  in any  manner  or  eliminating  any of the  provisions  of the
Indenture or of any supplemental indenture or modifying in any manner the rights
of the  holders  of the  Notes;  provided,  however,  that no such  supplemental
indenture shall (i) extend the fixed maturity of any Note, or reduce the rate or
extend the time of payment of interest  thereon,  or reduce the principal amount
thereof or premium,  if any, thereon, or reduce any amount payable on redemption
thereof, or impair the right of any Noteholder to institute suit for the payment
thereof,  or make the principal thereof or interest or premium,  if any, thereon
payable in any coin or currency  other than that provided in the Note, or modify
the provisions of the Indenture with respect to the  subordination  of the Notes
in a manner adverse to the  Noteholders in any material  respect,  or change the
obligation of the Company to make redemption of any Note upon the happening of a
Fundamental Change in a manner adverse to the holder of the Notes, or impair the
right to convert the Notes into Common  Stock  subject to the terms set forth in
the Indenture, including Section 15.6 thereof, without the consent of the holder
of each Note so affected or (ii) reduce the aforesaid  percentage of Notes,  the
holders of which are  required  to consent to any such  supplemental  indenture,
without  the consent of the  holders of all Notes then  outstanding.  It is also
provided  in the  Indenture  that,  prior to any  declaration  accelerating  the
maturity of the Notes,  the holders of a majority in aggregate  principal amount
of the Notes at the time  outstanding may on behalf of the holders of all of the
Notes waive any past  default or Event of Default  under

                                      -88-
<PAGE>

the Indenture and its  consequences  except a default in the payment of interest
or any premium on or the principal of any of the Notes, a default in the payment
of  redemption  price  pursuant  to Article  III or a failure by the  Company to
convert any Notes into Common Stock of the  Company.  Any such consent or waiver
by the holder of this Note (unless  revoked as provided in the Indenture)  shall
be  conclusive  and  binding  upon such  holder and upon all future  holders and
owners of this Note and any Notes which may be issued in exchange or  substitute
hereof,  irrespective  of whether or not any notation  thereof is made upon this
Note or such other Notes.

         The  indebtedness  evidenced  by the Notes is, to the extent and in the
manner provided in the Indenture,  expressly subordinate and subject in right of
payment to the prior payment in full of all Senior  Indebtedness of the Company,
as defined in the Indenture, whether outstanding at the date of the Indenture or
thereafter  incurred,  and this Note is issued  subject to the provisions of the
Indenture  with  respect to such  subordination.  Each  holder of this Note,  by
accepting  the  same,  agrees  to and  shall  be bound  by such  provisions  and
authorizes  the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination so provided and appoints the Trustee
his attorney-in-fact for such purpose.

         No reference  herein to the  Indenture and no provision of this Note or
of the Indenture  shall alter or impair the obligation of the Company,  which is
absolute and unconditional, to pay the principal of and any premium and interest
on this Note at the place, at the respective  times, at the rate and in the coin
or currency herein prescribed.

         Interest  on the  Notes  shall be  computed  on the  basis of a year of
twelve 30-day months.

         The  Notes  are  issuable  in  registered   form  without   coupons  in
denominations  of $1,000 and any integral  multiple of $1,000.  At the office or
agency of the  Company  referred  to on the face  hereof,  and in the manner and
subject to the  limitations  provided in the Indenture,  without  payment of any
service  charge but with payment of a sum  sufficient  to cover any tax or other
governmental  charge that may be imposed in connection with any  registration or
exchange of Notes, Notes may be exchanged for a like aggregate  principal amount
of Notes of other authorized denominations.

         The Notes will not be  redeemable at the option of the Company prior to
May 18, 2000. At any time on or after May 18, 2000,  and prior to maturity,  the
Notes may be redeemed  at the option of the Company as a whole,  or from time to
time in part,  upon  mailing a notice of such  redemption  not less than 30 days
before  the date  fixed for  redemption  to the  holders  of Notes at their last
registered  addresses,  all as  provided  in  the  Indenture,  at the  following
optional  redemption prices (expressed as percentages of the principal  amount),
together in each case with accrued  interest to, but  excluding,  the date fixed
for redemption:

and 100% at May 15, 2004; provided,  that if the date fixed for redemption is on
May 15 or November 15, then the  interest  payable on such date shall be paid to
the holder of record on the next preceding April 30 or October 31, respectively.

         The Notes are not subject to  redemption  through the  operation of any
sinking fund.

         If a  Fundamental  Change (as defined in the  Indenture)  occurs at any
time prior to May 15, 2004,  the Notes will be  redeemable on the 30th day after
notice  thereof  at the  option of the  holder.  Such  payment  shall be made at
106.000%  from the date of initial  issuance of the Notes until May 14, 1998; at
105.143%  from May 15, 1998 until May 14,  1999;  at 104.286%  from May 15, 1999
through May 17, 2000; at 103.429%  from May 18, 2000 until May 14, 2001,  and at
the following prices  (expressed as percentages of the principal  amount) in the
event of a Fundamental Change occurring during the 12-month period beginning May
15:

            Year                                                   Percentage
            ----                                                   ----------

            2002..............................................      101.714%
            2003..............................................      100.857%


and 100% at May 15, 2004; provided in each case that if the Applicable Price (as
defined in the Indenture) is less than the Reference Market Price (as defined in
the  Indenture),  the  Company  shall  redeem such Notes at a price equal to the
foregoing  repayment price  multiplied by the fraction  obtained by dividing the
Applicable  Price by the Reference Market Price. In each case, the Company shall
also pay  accrued  interest,  if any,  on such  Notes  to,  but  excluding,  the
repayment date; provided,  that if such repayment date is May 15 or November 15,
then the interest  payable on such date shall be paid to the holder of record of
the Note on the next preceding April 30 or October 31. The Company shall mail to
all holders of record of the Notes a notice of the  occurrence  of a Fundamental
Change and of the redemption  right arising as a result thereof on or before the
10th day after the occurrence of such  Fundamental  Change.  For a Note to be so
repaid at the option of the holder,  the Company  must  receive at the office or
agency of the Company  maintained  for that purpose in the Borough of Manhattan,

after the date of such  notice (or if such 30th day is not a Business  Day,  the
immediately preceding Business Day).

         Subject to the provisions of the  Indenture,  the holder hereof has the
right,  at its option,  at any time after 90 days  following  the latest date of
original  issuance  of the Notes and prior to the close of  business  on May 15,
2004,  or, as to all or any portion hereof called for  redemption,  prior to the
close of business on the Business Day  immediately  preceding the date fixed for
redemption  (unless the  Company  shall  default in payment due upon  redemption
thereof), to convert the principal hereof or any portion of such principal which
is  $1,000  or an  integral  multiple  thereof,  into  that  number of shares of
Company's  Common  Stock,  as said shares  shall be  constituted  at the date of
conversion,  obtained by dividing the  principal  amount of this Note or portion
thereof to be converted by the  Conversion  Price of $26.194 or such  Conversion
Price as adjusted from time to time as provided in the Indenture, upon surrender
of this Note, together with a conversion notice as provided in the Indenture, to
the Company at the office or agency of the Company  maintained  for that purpose
in the  Borough  of  Manhattan,  The City of New York,  or at the option of such
holder,  the  Corporate  Trust  Office,  and,  unless  the  shares  issuable  on
conversion are to be issued in the same name as this Note,  duly endorsed by, or
accompanied by instruments of transfer in form  satisfactory to the Company duly
executed by, the holder or by his duly  authorized  attorney.  No  adjustment in
respect of interest or  dividends  will be made upon any  conversion;  provided,
however, that if this Note shall be surrendered for conversion during the period
from the close of business on any record date for the payment of interest to the
close of business on the Business Day preceding the interest  payment date, this
Note  (unless it or the  portion  being  converted  shall  have been  called for
redemption  during the period  from the close of business on any record date for
the payment of interest to the close of business on the Business  Day  preceding
the  interest  payment  date)  must be  accompanied  by an  amount,  in New York
Clearing  House funds or other funds  acceptable  to the  Company,  equal to the
interest  payable on such interest  payment date on the  principal  amount being
converted.  No  fractional  shares  will be issued upon any  conversion,  but an
adjustment in cash will be made, as provided in the Indenture, in respect of any
fraction of a share which would  otherwise be issuable upon the surrender of any
Note or Notes for conversion.

         Any Notes called for redemption,  unless  surrendered for conversion on
or before the close of business on the date fixed for redemption,  may be deemed
to be  purchased  from  the  holder  of such  Notes  at an  amount  equal to the
applicable  redemption  price,  together with accrued interest to the date fixed
for redemption,  by one or more investment  bankers or other  purchasers who may
agree with the  Company to  purchase  such Notes from the  holders  thereof  and
convert them into Common Stock of the Company and to make payment for such Notes
as aforesaid to the Trustee in trust for such holders.

authenticating agent nor any paying agent nor any other conversion agent nor any
Note  registrar  shall be affected by any notice to the  contrary.  All payments

interest on this Note,  or for any claim based  hereon or  otherwise  in respect
hereof,  and no recourse under or upon any obligation,  covenant or agreement of
the Company in the  Indenture or any  indenture  supplemental  thereto or in any
Note, or because of the creation of any indebtedness  represented thereby, shall
be had  against  any  incorporator,  stockholder,  employee,  agent,  officer or

any  successor  corporation,  either  directly  or  through  the  Company or any
successor corporation, whether by virtue of any constitution, statute or rule of
law 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.

         This Note shall be deemed to be a  contract  made under the laws of New

         2.       Shelf Registration.

                                                                                
                  (a) Shelf  Registration.  The Company  shall  prepare and file
with the SEC,  as soon as  practicable  but in any event on or prior to the date
sixty (60) days following the latest date of original issuance of the Notes (the
"Filing  Date"),  a  Registration  Statement  for an  offering  to be  made on a
continuous  basis  pursuant  to  Rule  415  of  the  Securities  Act  (a  "Shelf
Registration")  registering  the resale from time to time by Holders  thereof of
all of the  Registrable  Securities  (the  "Initial  Shelf  Registration").  The
Initial  Shelf  Registration  shall be on Form S-3 or another  appropriate  form
permitting registration of such Registrable Securities for resale by the Holders
in the manner or manners  designated  by them.  If the  Holders of a

                                      -4-

<PAGE>

majority  of  Registrable  Securities  so  elect,  an  offering  of  Registrable
Securities  pursuant to the Shelf Registration  Statement may be effected in the
form of an  Underwritten  Offering;  provided  that  the  Company  shall  not be
obligated  to  arrange  for more than  three such  Underwritten  Offerings.  The
Company shall use its reasonable efforts to cause the Initial Shelf Registration
to be declared  effective under the Securities Act as soon as practicable and to
keep the Initial Shelf Registration  continuously effective under the Securities
Act until the earlier of the expiration of the Effectiveness  Period or the date
a  Subsequent  Shelf  Registration,  as  defined  below,  covering  all  of  the
Registrable Securities has been declared effective under the Securities Act.

                  (b) If the Initial Shelf  Registration or any Subsequent Shelf
Registration,  as  defined  below,  ceases to be  effective  for any reason as a
result  of the  issuance  of a stop  order  by the SEC at any  time  during  the
Effectiveness Period, the Company shall use its reasonable efforts to obtain the
prompt withdrawal of any order suspending the effectiveness  thereof, and in any
event shall within thirty (30) days of such cessation of effectiveness amend the
Shelf  Registration in a manner reasonably  expected to obtain the withdrawal of
the order  suspending the  effectiveness  thereof,  or file an additional  Shelf
Registration  covering all of the  Registrable  Securities (a "Subsequent  Shelf
Registration").  If a Subsequent Shelf  Registration is filed, the Company shall
use its reasonable  efforts to cause the  Subsequent  Shelf  Registration  to be
declared  effective  as soon as  practicable  after such filing and to keep such
Registration Statement continuously effective until the end of the Effectiveness
Period.

                  (c)  The  Company  shall   supplement   and  amend  the  Shelf
Registration if required by the rules, regulations or instructions applicable to
the  registration  form used by the  Company  for such  Shelf  Registration,  if
required  by the  Securities  Act,  or if  reasonably  requested  by the Initial
Purchasers  or by the  Trustee on behalf of the  Holders  of a  majority  of the
Registrable Securities covered by such Registration Statement or by any Managing
Underwriter  of such  Registrable  Securities  in the  event of an  Underwritten
Offering of the Registrable Securities.

                  (d) Each Holder of Registrable  Securities agrees that if such
Holder  wishes  to  sell  its  Registrable   Securities   pursuant  to  a  Shelf
Registration and related Prospectus,  it will do so only in accordance with this
Section  2(d).  Each Holder of  Registrable  Securities  agrees to give  written
notice  to the  Company  at least  five  Business  Days  prior  to any  intended
distribution  of  Registrable  Securities  under the Shelf  Registration,  which
notice  shall  specify  the date on which  such  Holder  intends  to begin  such
distribution  and any  information  with respect to such Holder and the intended
distribution  of  Registrable  Securities  by such  Holder as may be required to
amend the  Registration  Statement or  supplement  the related  Prospectus  with
respect to such intended  distribution of Registrable  Securities by such Holder
(the  "Requisite  Information").  In the event the Holder  fails to provide  the
Requisite  Information  in its initial notice of its intention to distribute the
Registrable Securities pursuant to the Registration Statement,  the Company will
promptly request such Holder to provide such Requisite  Information.  As soon as
practicable  after the date such notice and Requisite

                                      -5-
<PAGE>

Information  is provided,  and in any event within four Business Days after such
date, the Company shall either:

                  i. (A) If  necessary,  prepare and file with the  Commission a
post-effective  amendment  to the  Shelf  Registration  or a  supplement  to the
related  Prospectus  or a supplement  or amendment to any document  incorporated
therein  by  reference  or  file  any  other  required  document  so  that  such
Registration  Statement will not contain an untrue  statement of a material fact
or omit to state a material fact  required to be stated  therein or necessary to
make the statements therein not misleading, and so that, as thereafter delivered
to  purchasers  of  the  Registrable  Securities  being  sold  thereunder,  such
Prospectus will comply in all material  respects with the rules and requirements
under the Securities Act and will not contain an untrue  statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements  therein,  in light of the circumstances under which they
were made,  not  misleading;  (B) provide each Notice Holder (as defined  below)
copies of any documents  filed  pursuant to Section  2(d)(i)(A);  and (C) inform
each Notice Holder that the Company has complied with its obligations in Section
2(d)(i)(A) (or that, if the Company has filed a post-effective  amendment to the
Shelf Registration which has not yet been declared  effective,  the Company will
notify the Notice  Holder to that  effect,  will use its  reasonable  efforts to
secure the  effectiveness  of such  post-effective  amendment  and will promptly
notify the Notice Holder when the amendment has become  effective);  each Holder
who has given  notice of  intention  to  distribute  such  Holder's  Registrable
Securities in accordance with Section 2(d) hereof (a "Notice  Holder") will sell
all or any of such Registrable Securities pursuant to the Shelf Registration and
related  Prospectus  only during the 45-day period  commencing  with the date on
which the  Company  gives  notice,  pursuant  to  Section  2(d)(i)(C),  that the
Registration  Statement and Prospectus may be used for such purpose (such 45-day
period is referred to as a "Selling  Period").  The Notice Holders will not sell
any Registrable Securities pursuant to such Registration Statement or Prospectus
after such  Selling  Period  without  giving a new notice of  intention  to sell
pursuant to Section 2(d) hereof and receiving a further  notice from the Company
pursuant to Section 2(d)(i)(C) hereof.

                  ii. In the event (A) of the happening of any event of the kind
described in Section 3(c)(ii), 3(c)(iii),  3(c)(iv), 3(c)(v), or 3(c)(vi) hereof
or (B) that,  in the judgment of the Company,  it is advisable to suspend use of
the Prospectus for a discrete period of time due to pending  material  corporate
developments  or  similar  material  events  that  have  not yet  been  publicly
disclosed and as to which the Company believes that public  disclosure would not
be in the best interests of the Company, the Company shall deliver a certificate
in writing,  signed by an authorized  executive officer of the Company,  to each
Notice Holder, the Special Counsel and the Managing  Underwriters,  if any, that
the  use of the  Prospectus  has  been  suspended  and,  upon  receipt  of  such
certificate,  each such Notice  Holder's  Selling  Period  will not  commence or
resume,  as the case may be, until such Notice Holder's receipt of copies of the
supplemented or amended Prospectus provided for in Section 2(d)(i)(A) hereof, or
until it is advised in writing by the Company  that the  Prospectus  may be used
and has  received  copies of any  additional  or  supplemental  filings that are
incorporated or deemed incorporated

                                      -6-

<PAGE>

by reference in such Prospectus.  The Company will use its reasonable efforts to
ensure that the use of the  Prospectus  may be resumed,  and the Selling  Period
will commence or resume,  as the case may be, as soon as practicable and, in the
case of a  pending  development  or event  referred  to in  Section  2(d)(ii)(B)
hereof, as soon as the earlier of (x) public disclosure of such pending material
corporate  development  or similar  material event or (y) in the judgment of the
Company,  public  disclosure of such material  corporate  development or similar
material  event would be in the best  interests of the Company.  Notwithstanding
the  foregoing,  the Company  shall not under any  circumstances  be entitled to
exercise its right under this Section  2(d)(ii) to defer the  commencement  of a
Selling Period except as follows:  the Company may defer the  commencement  of a
Selling  Period in  accordance  with this  Section  2(d)(ii) for a period not to
exceed 30 days in any  three-month  period,  or not to exceed an aggregate of 60
days in any  12-month  period,  and the  period  for which a  Selling  Period is
suspended shall not exceed fifteen (15) days unless the Company shall deliver to
such Notice  Holders a second notice to the effect set forth above,  which shall
have the effect of extending  the period  during  which such  Selling  Period is
deferred by up to an  additional  fifteen (15) days,  or such shorter  period of
time as is  specified  in such second  notice.  In no event shall the Company be
permitted to extend the period  during which such Selling  Period is deferred (a
"Deferral  Period") beyond such thirty (30) day period from and after the date a
Notice Holder  provides  notice to the Company in  accordance  with this Section
2(d) of its intention to distribute Registrable Securities.

                  (e) The parties  hereto agree that the Holders of  Registrable
Securities will suffer  damages,  and that it would not be feasible to ascertain
the extent of such damages with precision, if (i) the Initial Shelf Registration
has not been filed on or prior to the Filing Date,  (ii) prior to the end of the
Effectiveness  Period,  the SEC shall have  issued a stop order  suspending  the
effectiveness of the Shelf  Registration or proceedings have been initiated with
respect to the Shelf  Registration  under Section 8(d) or 8(e) of the Securities
Act, (iii) the aggregate  number of days in any one Deferral  Period exceeds the
periods  permitted  pursuant  to Section  2(d)(ii)  hereof or (iv) the number of
Deferral  Periods  exceeds the number  permitted  pursuant  to Section  2(d)(ii)
hereof (each of the events of a type  described in any of the foregoing  clauses
(i) through  (iv) are  individually  referred  to herein as an "Event,"  and the
Filing Date in the case of clause (i),  the date on which the  effectiveness  of
the Shelf  Registration  has been suspended or  proceedings  with respect to the
Shelf  Registration  under Section 8(d) or 8(e) of the  Securities Act have been
commenced  in the case of  clause  (ii),  the date on which  the  duration  of a
Deferral Period exceeds the periods  permitted by Section 2(d)(ii) hereof in the
case of clause (iii), and the date of the commencement of a Deferral Period that
causes the limit on the number of Deferral Periods under Section 2(d)(ii) hereof
to be exceeded in the case of clause (iv), being referred to herein as an "Event
Date").  Events shall be deemed to continue until the date of the termination of
such Event,  which shall be the following  dates with respect to the  respective
types of Events:  the date the Initial  Registration  Statement  is filed in the
case of an Event of the type  described  in clause  (i),  the date that all stop
orders suspending  effectiveness of the Shelf Registration have been removed and
the proceedings  initiated with respect to the Shelf  Registration under Section
8(d) or 8(e) of the

                                      -7-

<PAGE>

Securities Act have terminated, as the case may be, in the case of Events of the
types described in clause (ii),  termination of the Deferral Period which caused
the  aggregate  number of days in any one  Deferral  Period to exceed the number
permitted  by Section  2(d)(ii) to be exceeded in the case of Events of the type
described  in  clause  (iii),   and  termination  of  the  Deferral  Period  the
commencement of which caused the number of Deferral Periods permitted by Section
2(d)(ii) to be exceeded  in the case of Events of the type  described  in clause
(iv).

         Accordingly,  upon the  occurrence  of any Event and until such time as
there are no Events which have occurred and are  continuing (a "Damages  Accrual
Period"),  commencing  on the Event Date on which such  Damages  Accrual  Period
began, the Company agrees to pay, as liquidated  damages,  and not as a penalty,
an additional amount (the "Liquidated Damages"): (A)(i) to each holder of a Note
that is a Notice Holder, accruing at a rate equal to one-half of one percent per
annum (50 basis points) on the aggregate  principal amount of Notes held by such
Notice  Holder and (ii) to each holder of Common Stock that is a Notice  Holder,
accruing at a rate equal to one-half of one percent per annum (50 basis  points)
calculated  on an  amount  equal  to  the  product  of (x)  the  then-applicable
Conversion Price (as defined in the Indenture),  or, in the event that each Note
has been converted to Common Stock,  the Conversion Price applicable to the Note
last  converted,  times (y) the  number of shares of Common  Stock  held by such
holder;  and (B) if the Damages Accrual Period  continues for a period in excess
of thirty (30) days from the Event  Date,  from and after the end of such thirty
(30) days until such time as there are no Events  which  have  occurred  and are
continuing,  (i) to each  holder  of a Note  (whether  or not a Notice  Holder),
accruing at a rate equal to one-half of one percent per annum (50 basis  points)
on the aggregate  principal amount of Notes held by such holder and (ii) to each
holder of Common  Stock  (whether  or not a Notice  Holder),  accruing at a rate
equal to one-half of one percent per annum (50 basis  points)  calculated  on an
amount  equal to the  product of (x) the then  applicable  Conversion  Price (as
defined in the  Indenture),  times (y) the number of shares of Common Stock held
by such holder.  Notwithstanding  the  foregoing,  no  Liquidated  Damages shall
accrue under clause (A) of the  preceding  sentence  during any period for which
Liquidated  Damages  accrue under clause (B) of the preceding  sentence or as to
any Registrable  Securities  from and after the expiration of the  Effectiveness
Period. The rate of accrual of the Liquidated Damages with respect to any period
shall not exceed the rate  provided for in this  paragraph  notwithstanding  the
occurrence of multiple concurrent Events.

         The Company shall pay the Liquidated Damages due on any Notes or Common
Stock by depositing  with the Trustee  under the  Indenture,  in trust,  for the
benefit of the holders of Notes or Common Stock or Notice  Holders,  as the case
may be,  entitled  thereto,  at least one Business  Day prior to the  applicable
Damages Payment Date,  sums sufficient to pay the Liquidated  Damages accrued or
accruing  since the last  preceding  Damages  Payment  Date through such Damages
Payment Date. The Liquidated  Damages shall be paid by the Trustee to the Record
Holders on each  Damages  Payment Date by wire  transfer of immediate  available
funds to the accounts specified by them or by mailing checks to their registered
addresses as they appear in the Note register (as defined in the Indenture),  in
the case of the Notes,  and in the register of the Company for the Common Stock,
in the case of the Common Stock,  if no

                                      -8-
<PAGE>

such  accounts  have  been  specified  on or before  the  Damage  Payment  Date;
provided,  however, that any Liquidated Damages accrued with respect to any Note
or portion  thereof  called for  redemption  on a redemption  date,  redeemed or
repurchased  in  connection  with  a  Fundamental  Change  (as  defined  in  the
Indenture) on a repurchase  date, or converted into Common Stock on a conversion
date prior to the  Damages  Payment  Date,  shall,  in any such  event,  be paid
instead to the holder who submitted such Note or portion thereof for redemption,
repurchase or conversion on the applicable  redemption date,  repurchase date or
conversion  date,  as the case may be, on such date (or promptly  following  the
conversion  date,  in the case of  conversion  of a Note).  The Trustee shall be
entitled,  on behalf of the holders of Notes, holders of Common Stock and Notice
Holders,  to seek any available  remedy for the  enforcement of this  Agreement,
including the payment of such Liquidated Damages. Notwithstanding the foregoing,
the parties agree that the sole damages  payable for a violation of the terms of
this Agreement with respect to which Liquidated  Damages are expressly  provided
shall be such  Liquidated  Damages.  Nothing  shall  preclude a Notice Holder or
Holder of Registrable Securities from pursuing or obtaining specific performance
or other  equitable  relief with respect to this  Agreement,  in addition to the
payment of Liquidated Damages.

         All of the Company's  obligations  set forth in this Section 2(e) which
are  outstanding  with respect to any  Registrable  Securities  at the time such
security  ceases to be a Registrable  Security  shall survive until such time as
all such  obligations  with respect to such security have been satisfied in full
(notwithstanding termination of the Agreement pursuant to Section 8(o)).

         The parties  hereto agree that the Liquidated  Damages  provided for in
this  Section 2(e)  constitute a reasonable  estimate of the damages that may be
incurred  by  Holders  of  Registrable   Securities   (other  than  the  Initial
Purchasers)  by reason of the failure of the Shelf  Registration  to be filed or
declared  effective or  unavailable  (absolutely  or as a practical  matter) for
effecting resales of Registrable  Securities,  as the case may be, in accordance
with the provisions hereof.

         3.   Registration   Procedures.   In  connection   with  the  Company's
registration  obligations under Section 2 hereof,  the Company shall effect such
registrations  to permit the sale of the  Registrable  Securities  in accordance
with the intended method or methods of disposition thereof, and pursuant thereto
the Company shall as expeditiously as possible:

                  (a) Prepare and file with the SEC a Registration  Statement or
Registration  Statements  on any  appropriate  form  under  the  Securities  Act
available for the sale of the  Registrable  Securities by the Holders thereof in
accordance with the intended method or methods of distribution  thereof, and use
its  reasonable  efforts to cause  each such  Registration  Statement  to become
effective and remain effective as provided herein;  provided, that before filing
any such  Registration  Statement or Prospectus or any amendments or supplements
thereto  (other  than  documents  that  would be  incorporated  or  deemed to be
incorporated therein by reference and that the Company is required by applicable
securities  laws or stock  exchange  requirements  to file)  the  Company  shall
furnish  to the  Initial  Purchasers,  the  Special  Counsel

                                      -9-
<PAGE>

and the  Managing  Underwriters  of such  offering,  if any,  copies of all such
documents proposed to be filed, which documents will be subject to the review of
the Initial Purchasers, the Special Counsel and such Managing Underwriters,  and
the Company shall not file any such Registration  Statement or amendment thereto
or any  Prospectus or any supplement  thereto (other than such documents  which,
upon filing,  would be  incorporated  or deemed to be  incorporated by reference
therein and that the Company is required by applicable  securities laws or stock
exchange  requirements  to file) to  which  the  Holders  of a  majority  of the
Registrable  Securities  covered by such  Registration  Statement,  the  Initial
Purchasers or the Special Counsel shall reasonably  object in writing within two
full Business Days.

                  (b)  Prepare  and  file  with  the  SEC  such  amendments  and
post-effective  amendments to each Registration Statement as may be necessary to
keep such  Registration  Statement  continuously  effective  for the  applicable
period  specified in Section 2; cause the related  Prospectus to be supplemented
by any  required  Prospectus  supplement,  and as so  supplemented  to be  filed
pursuant  to Rule  424 (or any  similar  provisions  then in  force)  under  the
Securities  Act;  and comply  with the  provisions  of the  Securities  Act with
respect  to the  disposition  of all  securities  covered  by such  Registration
Statement and  Prospectus  during the applicable  period in accordance  with the
intended  methods  of  disposition  by the  sellers  thereof  set  forth in such
Registration Statement as so amended or such Prospectus as so supplemented.

                  (c) Notify the Notice  Holders,  the Initial  Purchasers,  the
Special  Counsel  and  the  Managing  Underwriters,  if any,  promptly,  and (if
required  by any  such  person)  confirm  such  notice  in  writing,  (i) when a
Prospectus,   any  Prospectus   supplement,   a  Registration   Statement  or  a
post-effective  amendment to a  Registration  Statement  has been filed with the
SEC,  and,  with  respect  to a  Registration  Statement  or any  post-effective
amendment, when the same has become effective, (ii) of any request by the SEC or
any other federal or state governmental  authority for amendments or supplements
to a Registration statement or related Prospectus or for additional information,
(iii) of the suspension of the effectiveness of a Registration  Statement or the
initiation or  threatening  of any  proceedings  for that  purpose,  (iv) of the
receipt by the Company of any notification with respect to the suspension of the
qualification  or  exemption  from  qualification  of  any  of  the  Registrable
Securities for sale in any  jurisdiction or the initiation or threatening of any
proceeding  for such  purpose,  (v) of the existence of any fact or happening of
any event  which makes any  statement  of a material  fact in such  Registration
Statement or related  Prospectus  or any document  incorporated  or deemed to be
incorporated  therein by reference  untrue or which would  require the making of
any changes in the  Registration  Statement or  prospectus in order that, in the
case of the Registration  Statement, it will not contain any untrue statement of
a material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein not misleading, and that in the case
of the Prospectus,  it will not contain any untrue  statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements  therein, in the light of the circumstances under which they
were  made,  not  misleading,  and (vi) of the  Company's  determination  that a
post-effective amendment to a Registration Statement would be appropriate.

                                      -10-

<PAGE>

                  (d) Use its reasonable efforts to obtain the withdrawal of any
order suspending the effectiveness of a Registration  Statement,  or the lifting
of any suspension of the qualification  (or exemption for  qualification) of any
of the  Registrable  Securities  for sale in any  jurisdiction,  at the earliest
possible moment.

                  (e) If reasonably  requested by the Initial  Purchasers or the
Managing  Underwriters,  if any, or the Holders of a majority of the Registrable
Securities  being sold, (i) promptly  incorporate in a Prospectus  supplement or
post-effective  amendment to a Registration  Statement  such  information as the
Initial Purchasers,  the Special Counsel, the Managing Underwriters,  if any, or
such Holders, in connection with any offering of Registrable  Securities,  agree
should be  included  therein as required by  applicable  law,  and (ii) make all
required filings of such Prospectus supplement or such post-effective  amendment
as soon as  practicable  after the  Company  has  received  notification  of the
matters to be  incorporated  in such  Prospectus  supplement  or  post-effective
amendment;  provided, that the Company shall not be required to take any actions
under this Section (3)(e) that are not, in the reasonable opinion of counsel for
the Company, in compliance with applicable law.

                  (f) Furnish to each selling  Holder,  the Special  Counsel and
the Initial Purchasers,  and each Managing Underwriter,  if any, without charge,
at least one conformed copy of the Registration  Statement or Statements and any
amendment thereto,  including financial statements but excluding schedules,  all
documents incorporated or deemed to be incorporated therein by reference and all
exhibits (unless  requested in writing by such selling Holder,  Special Counsel,
the Initial Purchasers or the Managing Underwriters).

                  (g) Deliver to each selling  Holder,  the Special  Counsel and
the Initial Purchasers and each Managing Underwriter, if any, in connection with
any offering of Registrable  Securities,  without charge,  as many copies of the
Prospectus or Prospectuses  relating to such Registrable  Securities  (including
each  preliminary  prospectus)  and any amendment or supplement  thereto as such
persons may reasonably  request;  and the Company hereby  consents to the use of
such  Prospectus or each amendment or supplement  thereto by each of the selling
Holders of Registrable  Securities and the  underwriters,  if any, in connection
with  any  offering  and  sale of the  Registrable  Securities  covered  by such
Prospectus or any amendment or supplement thereto.

                  (h) Prior to any public offering of Registrable Securities, to
register  or  qualify  or  cooperate  with the  selling  Holders,  the  Managing
Underwriters,   if  any,  and  the  Special   Counsel  in  connection  with  the
registration  or   qualification   (or  exemption  from  such   registration  or
qualification)  of such  Registrable  Securities  for offer  and sale  under the
securities  or Blue Sky laws of such  jurisdictions  within the United States as
any selling Holder or Managing Underwriter  reasonably requests in writing; keep
each such  registration  or  qualification  (or exemption  therefrom)  effective
during the period such  Registration  Statement is required to be kept effective
and do any and all other acts or things  necessary  or  advisable  to

                                      -11-

<PAGE>

enable the  disposition  in such  jurisdictions  of the  Registrable  Securities
covered by the applicable  Registration  Statement;  provided,  that the Company
will not be required to (i) qualify generally to do business in any jurisdiction
where it is not then so qualified or (ii) take any action that would  subject it
to general  service of process in suits or to taxation in any such  jurisdiction
where it is not then so subject.

                  (i) Cause the Registrable Securities covered by the applicable
Registration  Statement  to  be  registered  with  or  approved  by  such  other
governmental  agencies or authorities within the United States, except as may be
required solely as a consequence of the nature of any selling  Holder,  in which
case the Company will  cooperate in all  reasonable  respects with the filing of
such  Registration  Statement  and the  granting  of such  approvals,  as may be
necessary  to enable  the  selling  Holder or Holders  thereof  or the  Managing
Underwriters,  if  any,  to  consummate  the  disposition  of  such  Registrable
Securities.

                  (j)  During any Selling  Period  (other than during a Deferral
Period)  immediately  upon the  existence of any fact or the  occurrence  of any
event  as a  result  of  which a  Registration  Statement  contains  any  untrue
statement of a material  fact or omits to state any material fact required to be
stated therein or necessary to make the statements therein not misleading,  or a
Prospectus  contains any untrue  statement of a material  fact or omits to state
any  material  fact  required  to be stated  therein  or  necessary  to make the
statements  therein,  in the light of the  circumstances  under  which they were
made,  not  misleading,  promptly  prepare  and file  (subject to the proviso in
Section 3(a)) a  post-effective  amendment to each  Registration  Statement or a
supplement  to the related  Prospectus or any document  incorporated  therein by
reference or file any other required  document (such as a Current Report on Form
8-K) that would be incorporated by reference into the Registration  Statement so
that the  Registration  Statement  shall not contain any untrue  statement  of a
material fact or omit to state any material  fact required to be stated  therein
or  necessary to make the  statements  therein not  misleading,  and so that the
Prospectus  will not contain any untrue  statement of a material fact or omit to
state any material fact  required to be stated  therein or necessary to make the
statements  therein,  in the light of the  circumstances  under  which they were
made,  not  misleading,  as  thereafter  delivered  to  the  purchasers  of  the
Registrable   Securities  being  sold   thereunder,   and,  in  the  case  of  a
post-effective amendment to a Registration Statement, use its reasonable efforts
to cause it to become effective as soon as practicable.

                  (k) Enter into such agreements (including,  in the event of an
Underwritten Offering, an underwriting agreement in form, scope and substance as
is  customary  in  Underwritten  Offerings)  and take all such other  actions in
connection therewith (including, in the event of an Underwritten Offering, those
reasonably requested by the Managing  Underwriters,  if any, or the Holders of a
majority  of the  Registrable  Securities  being  sold) in order to  expedite or
facilitate  the  disposition  of  such   Registrable   Securities  and  in  such
connection, whether or not an underwriting agreement is entered into, and if the
registration is an underwritten registration,  (i) make such representations and
warranties,  subject to the  Company's  ability to do so, to the Holders of such
Registrable  Securities and the underwriters

                                      -12-

with  respect  to  the  business  of  the  Company  and  its  subsidiaries,  the
Registration  Statement,  Prospectus and documents  incorporated by reference or
deemed incorporated by reference,  if any, in each case, in form,  substance and
scope  as are  customarily  made by  issuers  to  underwriters  in  underwritten
offerings and confirm the same if and when  requested;  (ii) use its  reasonable
efforts to obtain  opinions of counsel to the Company and updates thereof (which
counsel  and  opinions  (in  form,  scope  and  substance)  shall be  reasonably
satisfactory  to the  Managing  Underwriters,  if any,  Special  Counsel and the
Holders of a majority of the  Registrable  Securities  being sold)  addressed to
each of the underwriters  covering the matters  customarily  covered in opinions
requested in underwritten  offerings and such other matters as may be reasonably
requested  by such  Special  Counsel and  Managing  Underwriters;  (iii) use its
reasonable efforts to obtain "cold comfort" letters and updates thereof from the
independent accountants of the Company (and, if necessary, any other independent
accountants of any business  acquired or to be acquired by the Company for which
financial  statements and financial data are, or are required to be, included in
the Registration Statement),  addressed to the Board of Directors of the Company
and each of the Managing  Underwriters,  if any, such letters to be in customary
form and  covering  matters of the type  customarily  covered in "cold  comfort"
letters in connection  with the  Underwritten  Offerings;  and (iv) deliver such
documents and  certificates  as may be reasonably  requested by the Holders of a
majority of the Registrable  Securities  being sold, the Special Counsel and the
Managing  Underwriters,  if any,  to  evidence  the  continued  validity  of the
representations and warranties of the Company and its subsidiaries made pursuant
to clause (i) above and to evidence  compliance  with any  customary  conditions
contained in the underwriting  agreement or other agreement  entered into by the
Company.  The above shall be done at each  closing  under such  underwriting  or
similar agreement as and to the extent required thereunder.

                  (l)  If  requested  in  connection   with  a  disposition   of
Registrable Securities pursuant to a Registration Statement,  make available for
inspection by a  representative  of the Holders of Registrable  Securities being
sold, any Managing  Underwriter  participating in any disposition of Registrable
Securities,  if any,  and any  attorney or  accountant  retained by such selling
Holders  or  underwriter,  financial  and  other  records,  pertinent  corporate
documents  and  properties  of the Company and its  subsidiaries,  and cause the
executive officers,  directors and employees of the Company and its subsidiaries
to supply  all  information  reasonably  requested  by any such  representative,
Managing   Underwriter,   attorney  or  accountant   in  connection   with  such
disposition;  subject to  reasonable  assurances  by each such  person that such
information  will  only be used in  connection  with  matters  relating  to such
Registration Statement;  provided,  however, that such persons shall first agree
in writing with the Company that any information  that is reasonably and in good
faith  designated  by the  Company  in writing  as  confidential  at the time of
delivery of such information shall be kept confidential by such persons,  unless
(i) disclosure of such information is required by court or administrative  order
or is  necessary  to  respond  to  inquiries  of  regulatory  authorities,  (ii)
disclosure of such  information  is required by law  (including  any  disclosure
requirements  pursuant to Federal  securities laws in connection with the filing
of any Registration  Statement or the use of any Prospectus  referred to in this
Agreement),  (iii) such information  becomes  generally  available to the public
other  than as a

                                      -13-

<PAGE>

result of a  disclosure  or failure to safeguard by any such person or (iv) such
information  becomes  available  to any such person from a source other than the
Company and such source is not bound by a confidentiality agreement.

                  (m) Comply with all  applicable  rules and  regulations of the
SEC and make  generally  available to its security  holders  earning  statements
(which need not be audited)  satisfying  the  provisions of Section 11(a) of the
Securities Act and Rule 158 thereunder  (or any similar rule  promulgated  under
the Securities  Act) no later than 45 days after the end of any 12-month  period
(or 90 days  after the end of any  12-month  period  if such  period is a fiscal
year) (i)  commencing  at the end of any  fiscal  quarter  in which  Registrable
Securities  are  sold to  underwriters  in a firm  commitment  or  best  efforts
underwritten  offering and (ii) if not sold to underwriters in such an offering,
commencing  on  the  first  day of  the  first  fiscal  quarter  of the  Company
commencing  after  the  effective  date  of  a  Registration  Statement,   which
statements shall cover said 12-month periods.

                  (n)   Cooperate  with  the  selling   Holders  of  Registrable
Securities to facilitate  the timely  preparation  and delivery of  certificates
representing  Registrable  Securities to be sold and not bearing any restrictive
legends; and enable such Registrable  Securities to be in such denominations and
registered in such names as such Holders may request.

                  (o)  Provide the Trustee  under the Indenture and the transfer
agent  for the  Common  Stock  with  printed  certificates  for the  Registrable
Securities  which are in a form eligible for deposit with The  Depository  Trust
Company.

                  (p)  Cause  the  Common  Stock  covered  by  the  Registration
Statement to be listed on each  securities  exchange or quoted on each automated
quotation  system on which any of the Company's  "Common Stock," as that term is
defined in the  Indenture,  is then  listed or quoted no later than the date the
Registration  Statement is declared effective and, in connection  therewith,  to
the extent  applicable,  to make such filings under the Exchange Act (e.g.,  the
filing  of a  Registration  Statement  on Form  8-A)  and to have  such  filings
declared effective thereunder.

                  (q)  Cooperate  and assist in any filings  required to be made
with the National Association of Securities Dealers, Inc.

                  (r) Prior to any  registration  of the Notes  pursuant to this
Agreement, or at such earlier time as may be so required,  qualify the Indenture
under the Trust Indenture Act of 1939, as amended.

         4.   Holder's  Obligations.  Each Holder agrees,  by acquisition of the
Notes and Registrable Securities, that no Holder of Registrable Securities shall
be  entitled  to  sell  any  of  such  Registrable   Securities  pursuant  to  a
Registration Statement or to receive a Prospectus relating thereto,  unless such
Holder has  furnished  the  Company  with the notice and  Requisite

                                      -14-

<PAGE>

Information  required pursuant to Section 2(d) hereof and such other information
regarding such Holder and the distribution of such Registrable Securities as the
Company may from time to time reasonably  request.  The Company may exclude from
such registration the Registrable  Securities of any Holder who does not furnish
such  information  provided  above  for so long as  such  information  is not so
furnished.  Each Holder of Registrable  Securities as to which any  Registration
Statement  is being  effected  agrees  promptly  to furnish to the  Company  all
information required to be disclosed in order to make the information previously
furnished  to the  Company  by  such  Holder  not  misleading.  Any  sale of any
Registrable  Securities  by any Holder  shall  constitute a  representation  and
warranty  by such Holder  that the  information  relating to such Holder and its
plan of distribution is as set forth in the Prospectus  delivered by such Holder
in connection  with such  disposition,  that such  Prospectus does not as of the
time of such sale contain any untrue  statement of a material  fact  relating to
such Holder or its plan of distribution  and that such Prospectus does not as of
the time of such sale omit to state any material fact relating to such Holder or
its plan of distribution necessary to make the statements in such Prospectus, in
light of the circumstances under which they were made, not misleading.

         5.   Registration  Expenses.  All fees  and  expenses  incident  to the
Company's performance of or compliance with this Agreement shall be borne by the
Company whether or not any of the Registration Statements become effective. Such
fees and expenses shall include,  without  limitation,  (i) all registration and
filing fees (including,  without limitation,  fees and expenses (x) with respect
to  filings  required  to be made with the SEC or the  National  Association  of
Securities Dealers,  Inc. and (y) relating to compliance with federal securities
or Blue Sky laws  (including,  without  limitation,  fees and  disbursements  of
Special  Counsel in connection with Blue Sky  qualifications  of the Registrable
Securities under the laws of such jurisdictions as the Managing Underwriters, if
any,  or Holders  of a majority  of the  Registrable  Securities  being sold may
reasonably designate)),  (ii) printing expenses (including,  without limitation,
expenses of printing certificates for Registrable  Securities in a form eligible
for deposit with The Depository  Trust Company and of printing  prospectuses  if
the printing of  prospectuses is requested by the Special Counsel or the Holders
of a  majority  of the  Registrable  Securities  included  in  any  Registration
Statement),  (iii) the reasonable fees and  disbursements of the Trustee and its
counsel and of the  registrar  and  transfer  agent for the Common  Stock,  (iv)
messenger,  telephone and delivery  expense  relating to the  performance of the
Company's  obligations  hereunder,  (v)  reasonable  fees and  disbursements  of
counsel for the Company and the  Special  Counsel in  connection  with the Shelf
Registration  (provided  that the  Company  shall not be liable for the fees and
expenses of more than one separate firm, in addition to counsel for the Company,
for all  parties  participating  in any  transaction  hereunder),  (vi) fees and
disbursements of all independent  accountants  referred to in Section  3(k)(iii)
hereof  (including the expenses of any special audit and "cold comfort"  letters
required by or incident to such  performance) and (vii) Securities Act liability
insurance,  to the extent  obtained  by the Company in its sole  discretion.  In
addition,  the  Company  shall pay its  internal  expenses  (including,  without
limitation,  all salaries and expenses of its officers and employees  performing
legal or  accounting  duties),  the  expense of any annual  audit,  the fees and
expenses

                                      -15-
<PAGE>

incurred in  connection  with the listing of the  securities to be registered on
any securities  exchange on which similar  securities  issued by the Company are
then listed and the fees and expenses of any person,  including special experts,
retained by the Company.  Notwithstanding the provisions of this Section 5, each
seller of Registrable  Securities shall pay (a) all  underwriting  discounts and
commissions,  all  fees and  expenses  of its  counsel  in  connection  with any
Underwritten  Offering and all other  selling and  registration  expenses to the
extent that the Company is prohibited  by  applicable  Blue Sky laws from paying
such other selling and registration  expenses for or on behalf of such seller of
Registrable  Securities;  and (b) all fees and expenses in  connection  with any
Underwritten  Offering  occuring  after the first  Underwritten  Offering to the
extent  that such fees and  expenses  exceed the fees and  expenses  incurred in
connection   with  an  offering  of  Registrable   Securities  that  is  not  an
Underwritten Offering.

         6.      Indemnification.

                  (a)   Indemnification  by  the  Company.   The  Company  shall
indemnify and hold harmless each Initial Purchaser, each Holder and each person,
if any, who controls either Initial  Purchaser or any Holder (within the meaning
of either Section 15 of the Securities Act of Section 20(a) of the Exchange Act)
from and against  all losses,  liabilities,  damages  and  expenses  (including,
without  limitation,   any  legal  or  other  expenses  reasonably  incurred  in
connection   with  defending  or   investigating   any  such  action  or  claim)
(collectively,  "Losses"),  arising out of or based upon any untrue statement or
alleged  untrue  statement  of a material  fact  contained  in any  Registration
Statement or  Prospectus  or in any  amendment or  supplement  thereto or in any
preliminary prospectus,  or arising out of or based upon any omission or alleged
omission  to state  therein a material  fact  required  to be stated  therein or
necessary to make the  statements  therein not  misleading,  except as to either
Initial Purchaser or any Holder insofar as such Losses arise out of or are based
upon the information  relating to any Initial Purchaser or such Holder furnished
to the Company in writing by such Initial Purchaser or such Holder expressly for
use  therein;  provided,  that the Company  shall not be liable to any Holder of
Registrable  Securities  (or any person  controlling  such Holder) to the extent
that any such  Losses  arise out of or are based  upon an  untrue  statement  or
alleged untrue statement or omission or alleged omission made in any preliminary
prospectus  if either (A)(i) such Holder failed to send or deliver a copy of the
Prospectus with or prior to delivery of written confirmation of the sale by such
Holder to the person  asserting the claims from which such Losses arise and (ii)
the  Prospectus  would have  corrected  such untrue  statement or alleged untrue
statement or such omission or alleged omission,  or (B)(x) such untrue statement
or alleged  untrue  statement,  omission or alleged  omission is corrected in an
amendment  or  supplement  to the  Prospectus  and (y)  having  previously  been
furnished  by or on behalf of the Company  with copies of the  Prospectus  as so
amended or supplemented, such Holder thereafter fails to deliver such Prospectus
as so  amended  or  supplemented,  with or  prior  to the  delivery  of  written
confirmation of the sale of a Registrable  Security to the person  asserting the
claim from which such  Losses  arise.  The  Company  shall also  indemnify  each
underwriter  and each person who  controls  such  person  (within the meaning of
Section 15 of the  Securities  Act

                                      -16-

<PAGE>

or  Section  20(a) of the  Exchange  Act) to the same  extent  and with the same
limitations as provided above with respect to the indemnification of the Initial
Purchasers or the Holders of Registrable Securities.

                  (b) Indemnification by Holder of Registrable Securities.  Each
Holder agrees,  and such agreement  shall be evidenced by the Holder  delivering
the notice  described  in Section  2(d) hereof,  severally  and not jointly,  to
indemnify and hold harmless the Initial  Purchasers,  the other selling Holders,
the Company, its directors,  its officers who sign a Registration Statement, and
each person,  if any, who controls the Company,  the Initial  Purchasers and any
other selling  Holder (within the meaning of either Section 15 of the Securities
Act or Section 20 of the Exchange Act),  from and against all losses arising out
of or based  upon any  untrue  statement  of a material  fact  contained  in any
Registration  Statement,  Prospectus or preliminary prospectus or arising out of
or based upon any omission of a material fact  required to be stated  therein or
necessary to make the statements therein not misleading, to the extent, but only
to the extent  that such  untrue  statement  or  omission  is  contained  in any
information  relating to such Holder so  furnished  in writing by such Holder to
the Company expressly for use in such Registration  Statement or Prospectus.  In
no event shall the  liability of any selling  Holder of  Registrable  Securities
hereunder be greater in amount than the dollar  amount of the proceeds  received
by such Holder upon the sale of the Registrable  Securities  giving rise to such
indemnification obligation.

                  (c)  Conduct  of  Indemnification  Proceedings.  In  case  any
proceeding  (including  any  governmental  investigation)  shall  be  instituted
involving  any person in respect of which  indemnity  may be sought  pursuant to
either of the two preceding  paragraphs,  such person (the "indemnified  party")
shall promptly  notify the person against whom such indemnity may be sought (the
"indemnifying party") in writing and the indemnifying party, upon request of the
indemnified  party,   shall  retain  counsel  reasonably   satisfactory  to  the
indemnified  party  to  represent  the  indemnified  party  and any  others  the
indemnifying party may designate in such proceeding and shall pay the reasonable
fees and  disbursements of such counsel related to such proceeding.  In any such
proceeding,  any  indemnified  party  shall  have the  right to  retain  its own
counsel,  but the fees and expenses of such  counsel  shall be at the expense of
such  indemnified  party unless (i) the  indemnifying  party and the indemnified
party shall have  mutually  agreed to the  retention of such counsel or (ii) the
named parties to any such proceeding  (including any impleaded  parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel  would be  inappropriate  due to actual or potential
differing interests between them.

It is understood that the indemnifying  party shall not, in respect of the legal
expenses of any  indemnified  party in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for (a) the fees and expenses of
more than one separate  firm (in addition to any local  counsel) for the Initial
Purchasers and all persons,  if any, who control the Initial  Purchasers  within
the  meaning  of either  Section 15 of the  Securities  Act or Section 20 of the
Exchange  Act,  (b) the fees and  expenses  of more than one  separate  firm (in
addition to any

                                      -17-

<PAGE>

local  counsel) for all Holders and all persons,  if any, who control any Holder
within the meaning of either  Section 15 of the  Securities Act or Section 20 of
the Exchange  Act, and (c) the fees and expenses of more than one separate  firm
(in addition to any local counsel) for the Company, its directors,  its officers
who sign a  Registration  Statement  and each  person,  if any, who controls the
Company  within the meaning of either such  Section,  and that all such fees and
expenses  shall  be  reimbursed  as they are  incurred.  In the case of any such
separate firm for the Company, and such directors,  officers and control persons
of the Company, such firm shall be designated in writing by the Company. In such
case  involving  the  Initial  Purchasers  and  persons  who control the Initial
Purchasers,  such firm shall be  designated  in writing by Morgan  Stanley & Co.
Incorporated.  In such case  involving  the Holders and such persons who control
the  Holders,  such firm shall be  designated  in writing by the  Holders of the
majority of Registrable Securities sold pursuant to the Registration  Statement.
The indemnifying  party shall not be liable for any settlement of any proceeding
effected  without its written  consent,  but if settled  with such consent or if
there be a final judgment for the plaintiff,  the  indemnifying  party agrees to
indemnify the indemnified party from and against any loss or liability by reason
of such settlement or judgment.  Notwithstanding the foregoing  sentence,  if at
any time an  indemnified  party shall have  requested an  indemnifying  party to
reimburse the indemnified party for fees and expenses of counsel as contemplated
by the second and third  sentences of this  paragraph,  the  indemnifying  party
agrees that it shall be liable for any  settlement  of any  proceeding  effected
without its written  consent if (i) such settlement is entered into more than 45
days after receipt by such indemnifying  party of the aforesaid request and (ii)
such  indemnifying  party shall not have  reimbursed  the  indemnified  party in
accordance  with  such  request  prior  to  the  date  of  such  settlement.  No
indemnifying  party shall,  without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened  proceeding in respect
of which any indemnified party is or could have been a party and indemnity could
have been sought  hereunder by such  indemnified  party,  unless such settlement
includes an unconditional  release of such indemnified  party from all liability
or claims that are the subject matter of such proceeding.

                  (d) Contribution.  If the indemnification provided for in this
Section 6 is  unavailable  to an  indemnified  party under  Section 6(a) or 6(b)
hereof in  respect  of any Losses or is  insufficient  to hold such  indemnified
party harmless, then each applicable indemnifying party, in lieu of indemnifying
such indemnified  party,  shall contribute to the amount paid or payable by such
indemnified  party as a result  of such  Losses,  (i) in such  proportion  as is
appropriate to reflect the relative benefits received by the indemnifying  party
or  parties  on the one hand and the  indemnified  party or parties on the other
hand or (ii) if the allocation  provided by clause (i) above is not permitted by
applicable  law, in such  proportion as is  appropriate  to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the indemnifying  party or parties on the one hand and of the indemnified  party
or parties on the other hand in connection with the statements or omissions that
resulted in such Losses, as well as any other relevant equitable considerations.
Benefits  received by the  Company  shall be deemed to be equal to the total net
proceeds from the initial  placement  (before  deducting  expenses) of the Notes
pursuant to the Placement Agreement. Benefits

                                      -18-

<PAGE>

received  by the  Initial  Purchasers  shall be  deemed to be equal to the total
purchase  discounts and  commissions  received by them pursuant to the Placement
Agreement and benefits received by any other Holders shall be deemed to be equal
to the value of receiving Notes  registered  under the Securities Act.  Benefits
received  by  any  underwriter  shall  be  deemed  to  be  equal  to  the  total
underwriting  discounts and  commissions,  as set forth on the cover page of the
Prospectus  forming a part of the Registration  Statement which resulted in such
Losses. The relative fault of the Holders on the one hand and the Company on the
other hand shall be determined by reference to, among other things,  whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Holders
or by the  Company  and the  parties'  relative  intent,  knowledge,  access  to
information  and  opportunity  to correct or prevent such statement or omission.
The Holders' respective obligations to contribute pursuant to this paragraph are
several in proportion to the respective  number of Registrable  Securities  they
have sold pursuant to a Registration Statement, and not joint.

         The parties  hereto  agree that it would not be just and  equitable  if
contribution  pursuant  to  this  Section  6(d)  were  determined  by  pro  rata
allocation or by any other method or allocation  that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
The amount  paid or payable  by an  indemnified  party as a result of the Losses
referred to in the immediately  preceding  paragraph shall be deemed to include,
subject  to the  limitations  set  forth  above,  any  legal or  other  expenses
reasonably  incurred by such indemnified party in connection with  investigating
or defending  any such action or claim.  Notwithstanding  this Section  6(d), an
indemnifying party that is a selling Holder of Registrable  Securities shall not
be required to contribute  any amount in excess of the amount by which the total
price at which the Registrable  Securities sold by such  indemnifying  party and
distributed  to the public were offered to the public  exceeds the amount of any
damages  which such  indemnifying  party has  otherwise  been required to pay by
reason of such  untrue or  alleged  untrue  statement  or  omission  or  alleged
omission. No person guilty of fraudulent  misrepresentation  (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to  contribution  form
any person who was not guilty of such fraudulent misrepresentations.

         The indemnity,  contribution and expense  reimbursement  obligations of
the Company  hereunder  shall be in addition  to any  liability  the Company may
otherwise  have  hereunder,  under the  Placement  Agreement or  otherwise.  The
provisions  of this Section 6 shall  survive so long as  Registrable  Securities
remain outstanding,  notwithstanding any transfer of the Registrable  Securities
by any Holder or any termination of this Agreement.

         The indemnity and contribution  provisions  contained in this Section 6
shall  remain  operative  and in full  force and  effect  regardless  of (i) any
termination of this Agreement,  (ii) any  investigation  made by or on behalf of
the Initial Purchasers,  any Holder or any person controlling any Holder, or the
Company,  its officers or directors  or any person  controlling  the Company and
(iii) the sale of any Registrable Securities by any Holder.

      7.       Information Requirements.

                  (a) The Company shall file the reports required to be filed by
it under the Securities Act and the Exchange Act, and if at any time the Company
is not required to file such reports, it will, upon the request of any Holder of
Registrable  Securities,  make publicly  available other  information so long as
necessary  to  permit  sales  pursuant  to Rule  144 and  Rule  144A  under  the
Securities  Act. The Company  further  covenants that it will cooperate with any
Holder of Registrable  Securities and take such further reasonable action as any
Holder of  Registrable  Securities may reasonably  request  (including,  without
limitation,  making  such  reasonable  representations  as any such  Holder  may
reasonably request), all to the extent required from time to time to enable such
Holder to sell Registrable  Securities without registration under the Securities
Act within the limitation of the  exemptions  provided by Rule 144 and Rule 144A
under  the  Securities  Act.  Upon the  request  of any  Holder  of  Registrable
Securities,  the Company shall deliver to such Holder a written  statement as to
whether it has  complied  with such  filing  requirements.  Notwithstanding  the
foregoing,  nothing in this  Section 7 shall be deemed to require the Company to
register any of its securities under any section of the Exchange Act.

                  (b) The Company shall file the reports required to be filed by
it under the Exchange Act and shall comply with all other requirements set forth
in the  General  Instructions  IA and B(4) to Form  S-3 in  order  to allow  the
Company to be eligible to file registration statements on Form S-3 in connection
with secondary offerings.

         8.       Miscellaneous.

                  (a)  Remedies.  In the event of a breach by the Company of its
obligations  under this  Agreement,  each Holder of Registrable  Securities,  in
addition  to being  entitled to exercise  all rights  granted by law,  including
recovery of damages,  will be  entitled  to specific  performance  of its rights
under this Agreement;  provided that the sole damages payable for a violation of
the terms of this Agreement for which Liquidated  Damages are expressly provided
pursuant to Section 2(e) hereof shall be such  Liquidated  Damages.  The Company
agrees that  monetary  damages would not be adequate  compensation  for any loss
incurred by reason of a breach by it of any of the  provisions of this Agreement
and  hereby  further  agrees  that,  in the  event of any  action  for  specific

any agreement  with respect to its  securities  which  conflicts with the rights
granted to the Holders of Registrable Securities in this Agreement.  The Company
represents  and warrants that the rights  granted to the Holders of  Registrable
Securities  hereunder do not in any way conflict with the rights  granted to the
holders of the Company's securities under any other agreements.

including  the  provisions  of this  sentence,  may not be amended,  modified or
supplemented,  and waivers or consents to departures from the provisions  hereof

depart  from  the  provisions  hereof  with  respect  to a matter  that  relates

or indirectly  affect the rights of other Holders of Registrable  Securities may
be given by Holders of at least a majority of the Registrable  Securities  being
sold by such Holders;  provided, that the provisions of this sentence may not be
amended,  modified,  or supplemented except in accordance with the provisions of
the immediately preceding sentence.

purposes,  of the number of  outstanding  shares of Common Stock into which such
Notes are convertible and (ii) Registrable Securities held by the Company or its
Affiliates  (other  than  the  Initial   Purchasers  or  subsequent  Holders  of
Registrable  Securities  if  such  subsequent  Holders  are  deemed  to be  such
affiliates  solely by reason of their holdings of such  Registrable  Securities)
shall not be counted in  determining  whether such consent or approval was given
by the Holders of such required percentage.

                  (g)  Successors  and  Assigns.  Any person who  purchases  any
Registrable  Securities from an Initial Purchaser shall be deemed,  for purposes
of this Agreement, to be an assignee of such Initial Purchasers.  This Agreement
shall inure to the benefit of and be binding upon the  successors and assigns of
each of the parties  and shall inure to the benefit of and be binding  upon each
Holder of any Registrable Securities.
                                                                    
                  (h) Counterparts. This Agreement may be executed in any number
of  counterparts  and by the parties  hereto in separate  counterparts,  each of
which when so  executed  shall be deemed to be  original  and all of which taken
together shall constitute one and the same agreement.

                  (i)  Headings.   The  headings  in  this   Agreement  are  for
convenience  of  reference  only and  shall not limit or  otherwise  affect  the

documents contemplated hereby and consummate and make effective the transactions
contemplated hereby.

                  (o)  Termination.  This  Agreement and the  obligations of the
parties  hereunder  shall  terminate upon the end of the  Effectiveness  Period,
except for any  liabilities or  obligations  under Sections 4, 5 or 6 hereof and

Data General Corporation

Westboro, Massachusetts  01580

Dear Sirs:

         We refer to the Registration  Statement on Form S-3 (the  "Registration
Statement") to be filed by Data General  Corporation  (the  "Company")  with the
Securities and Exchange Commission under the Securities Act of 1933, as amended,
relating to (i)  $212,750,000  aggregate  principal  amount of the  Company's 6%
Convertible  Subordinated Notes due 2004 (the "Notes") and (ii) 8,122,089 shares
of common stock, par value $.01 per share (the "Common  Stock"),  of the Company
which are initially  issuable upon conversion of the Notes, plus such additional
number of shares of Common Stock as may become  issuable upon  conversion of the
Notes as a result of adjustments to the conversion price.

         We have examined and are familiar with  originals or copies,  certified
or  otherwise  identified  to our  satisfaction,  of such  documents,  corporate
records,  certificates of public  officials and officers of the Company and such
other  instruments as we have deemed necessary or appropriate as a basis for the
opinions expressed below,  including the Registration  Statement,  the Indenture
under which the Notes were issued, the Restated  Certificate of Incorporation of
the Company and the By-Laws of the Company.

         Based on the foregoing, we advise you that in our opinion:

                  1. The Notes are valid,  legal and binding  obligations of the
Company,  enforceable against the Company in accordance with their terms, except
as enforcement thereof may be limited by bankruptcy, insolvency,  reorganization
or other  similar laws  affecting  creditors'  rights  generally  and by general
principles of equity, regardless of whether considered in equity or at law; and

                  2. The Common Stock issuable upon  conversion of the Notes has
been validly  authorized  and reserved  for issuance  and,  when duly issued and
delivered  upon  conversion  of the  Notes in  accordance  with the terms of the
Notes, will be validly issued, fully paid and nonassessable.

              We hereby  consent to the filing of this  opinion as an exhibit to
the  Registration  Statement  and the  reference  to this firm under the caption
"Legal Matters" in the Prospectus  contained therein.  This consent is not to be
construed as an admission  that we are a person whose  consent is required to be
filed with the Registration Statement under the provisions of the Securities Act
of 1933.


                                Very truly yours,
