     advances to the Subsidiary exceed 10 percent of the total assets of the
     Company and its Subsidiaries consolidated as of the end of the most
     recently completed fiscal year (for a proposed business combination to be
     accounted for as a pooling of interest, this condition is also met when the
     number of common shares exchanged or to be exchanged by the Company exceeds
     10 percent of its total common shares outstanding at the date the
     combination is initiated); or

          (2) The Company's and its other Subsidiaries' proportionate share of
     the total assets (after intercompany eliminations) of the Subsidiary
     exceeds 10 percent of the total assets of the Company's and its
     Subsidiaries consolidated as of the end of the most recently completed

          (4) Except in the case of an Event of Default specified in clauses (g)
     and (h) of Section 8.01 hereof in which case this clause (4) shall not
     apply, the total revenues of the Subsidiary exceed 5 percent of total
     revenues of the Company and its Subsidiaries consolidated as of the end of
     the most recently completed fiscal year.

For purposes of making the prescribed income test set forth above, the following
guidance should be applied:

     equity in the income or loss of the tested Subsidiary should be excluded
     from the income of the Company and its Subsidiaries consolidated for
     purposes of the computation.

          (2) If income of the Company and its Subsidiaries consolidated for the
     most recent fiscal year is at least 10 percent lower than the average of
     the income for the last five fiscal years, such average income should be
     substituted for purposes of the computation. Any loss years should be
     omitted for purposes of computing average income.

                                   ARTICLE II

                                    The Notes
                                    ---------

          SECTION 2.01. Form and Dating. The Notes and the Trustee's certificate
                        ---------------
of authentication shall be substantially in the form of Exhibit A which is
hereby incorporated in and expressly made a part of this Indenture. The Notes
may have notations, legends or endorsements required by law, stock exchange
rule, agreements to which the Company is subject, if any, or usage (provided
that any such notation, legend or endorsement is in a form acceptable to the
Company). The Company shall furnish any such legend not contained in Exhibit A
to the Trustee in writing. Each Note shall be dated the date of its
authentication. The terms and provisions of the Notes set forth in Exhibit A are
part of the terms of this Indenture and to the extent applicable, the Company
and the Trustee, by their execution and delivery of this Indenture, expressly
agree to such terms and provisions and to be bound thereby.

          (a) Global Notes. The Notes shall be issued in the form of one or more
              ------------
global Notes in fully registered form without interest coupons with the Global
Notes Legend set forth in Exhibit A hereto (each, a "Global Note"). The
aggregate principal amount of the Global Note may from time to time be increased
or decreased by adjustments made on the records of the Trustee and the
Depositary or its nominee as hereinafter provided.

          (b) Book-Entry Provisions. This Section 2.01(b) shall apply only to a
              ---------------------
Global Note deposited with or on behalf of the Depositary.

          The Company shall execute and the Trustee shall, in accordance with
this Section 2.01(b), authenticate and deliver initially one or more Global
Notes that (a) shall be registered in the name of Cede & Co. or other nominee of
such Depositary and (b) shall be delivered by the Trustee to such Depositary or
pursuant to such Depositary's instructions or held by the Trustee as custodian
for the Depositary pursuant to a FAST Balance Certificate Agreement between the
Depositary and the Trustee.

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

                                       -7-

<PAGE>

Global Note will not be entitled to have Notes registered in their names, will
not receive or be entitled to receive Notes in definitive registered form and
will not be considered owners or holders thereof under this Indenture.

          (c) Certificated Notes. Except as provided in this subparagraph (c),
              ------------------
Notes will not be issued in definitive registered form. If at any time the
Depositary notifies the Company that it is unwilling or unable to continue as
depositary for the Global Notes or if at any time the Depositary ceases to be a
clearing agency registered under the Exchange Act, or otherwise ceases to be
eligible to be a depositary, the Company shall appoint a successor depositary
with respect to the Global Notes. If a successor depositary for the Global Notes
is not appointed by the Company within 90 days after the Company receives such
notice or becomes aware of such ineligibility, the Company shall execute Notes
in definitive registered form without coupons ("Certificated Notes") and the
Trustee, upon receipt thereof, shall authenticate and deliver such Certificated
Notes, in denominations of U.S.$1,000 and integral multiples thereof, in an
aggregate principal amount equal to the aggregate principal amount of such
Global Notes as of the exchange date. Upon the exchange of the Global Notes for
Certificated Notes, the Trustee shall cancel such Global Notes. In addition, if
there is an Event of Default under the Notes or the Indenture, the Depositary
will, if the Trustee so requests, exchange the Global Notes for Certificated
Notes, which will be distributed to its participants.

          In the event of the occurrence of either of the events specified in
this Section 2.01(c), the Company will promptly make available to the Trustee a
reasonable supply of Certificated Notes.

          SECTION 2.02. Execution and Authentication. The Notes shall be signed
                        ----------------------------
on behalf of the Company by the Chairman of its Board of Directors, any Vice
Chairman of its Board of Directors, its Chief Executive Officer, its President,
any Executive Vice President, or any Vice President, under its corporate seal.
Such signatures may be the manual or facsimile signatures of the present or any
future such officers. The seal of the Company may be in the form of a facsimile
thereof and may be impressed, affixed, imprinted or otherwise reproduced on the
Notes and shall be attested by the Secretary or an Assistant Secretary of the
Company. Typographical and other minor errors or defects in any such
reproduction of the seal or any such signature shall not affect the validity or
enforceability of any Note that has been duly authenticated and delivered by the
Trustee.

          In case any officer of the Company who shall have signed any of the
Notes shall cease to be such officer before the Note so signed shall be
authenticated and delivered by the Trustee or disposed of by the Company, such
Note nevertheless may be authenticated and delivered or disposed of as though
the Person who signed such Note had not ceased to be such officer of the
Company; and any Note may be signed on behalf of the Company by such Persons as,
at the actual date of the execution of such Note, shall be the proper officers
of the Company, although at the date of the execution and delivery of this
Indenture any such Person was not such an officer.

                                       -8-

<PAGE>

          A Note shall not be valid until authenticated by the manual signature
of an authorized signatory of the Trustee. The signature shall be conclusive
evidence that the Note has been authenticated under this Indenture.

          Upon a written order of the Company signed by two Officers, the
Trustee shall authenticate the Notes for original issue up to an aggregate
principal amount of $120,000,000 (plus up to $18,000,000 aggregate principal
amount of Notes that may be sold by the Company pursuant to the over-allotment
option granted to the Underwriters pursuant to the Underwriting Agreement dated
July 16, 1996 between the Company and the Underwriters). The aggregate principal
amount of Notes outstanding at any time shall not exceed such amount except as
provided in Section 2.07.

          The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Notes. An authenticating agent may authenticate Notes
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with the Company or
an Affiliate of the Company.

          SECTION 2.03. Registrar, Paying Agent and Conversion Agent. The
                        --------------------------------------------
Company shall maintain (i) an office or agency where Notes may be presented for
registration of transfer or for exchange, (ii) an office or agency where Notes
may be presented for payment and (iii) an office or agency where Notes may be
presented for conversion. The Trustee is hereby appointed (i) "Registrar" for
the purpose of registering Notes and transfers of Notes as herein provided, (ii)
"Paying Agent" for the purpose of making payments on the Notes as herein
provided and (iii) "Conversion Agent" for the purpose of effecting conversion of
the Notes as herein provided. The Registrar shall keep a register of the Notes
and of their transfer and exchange. The Company may appoint one or more
co-registrars, one or more additional paying agents and one or more additional
conversion agents in such other locations as it shall determine. The term
"Paying Agent" includes any additional paying agent and the term "Conversion
Agent" includes any additional conversion agent. The Company may change any
Paying Agent, Registrar, co-registrar or Conversion Agent without prior notice
to any Noteholder. The Company shall notify the Trustee of the name and address
of any Agent not a party to this Indenture. If the Company fails to appoint or
maintain another entity as Registrar, Paying Agent or Conversion Agent, the
Trustee shall act as such. The Company or any of its Affiliates may act as
Paying Agent, Registrar, co-registrar or Conversion Agent.

          SECTION 2.04. Paying Agent To Hold Money in Trust. The Company shall
                        -----------------------------------
require each Paying Agent other than the Trustee to agree in writing that the
Paying Agent will hold in trust for the benefit of Noteholders or the Trustee
all money held by the Paying Agent for the payment of principal or interest on
the Notes, and will notify the Trustee of any default by the Company in making
any such payment. While any such default continues, the Trustee may require a
Paying Agent to pay all money held by it to the Trustee. The Company at any time
may require a Paying Agent to pay all money held by it to the Trustee and to
account for any money disbursed by it. Upon payment over to the Trustee, the
Paying Agent (if other than the Company or an Affiliate of the Company) shall
have no further liability for the money. If the

                                       -9-

<PAGE>

Company or an Affiliate of the Company acts as Paying Agent, it shall segregate
and hold in a separate trust fund for the benefit of the Noteholders all money
held by it as Paying Agent.

          SECTION 2.05. Noteholder Lists. The Trustee shall preserve in as
                        ----------------
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Noteholders. If the Trustee is not the Registrar,
the Company shall furnish to the Trustee on or before each interest payment date
and at such other times as the Trustee may request in writing a list in such
form and as of such date as the Trustee may reasonably require of the names and
addresses of Noteholders.

          SECTION 2.06. Transfer and Exchange. Where Notes are presented to the
                        ---------------------
Registrar or a co-registrar with a request to register a transfer or to exchange
them for an equal principal amount of Notes of other denominations, the
Registrar shall register the transfer or make the exchange if its requirements
for such transactions are met. To permit registrations of transfers and
exchanges, the Company shall issue and the Trustee shall authenticate Notes at
the Registrar's request. No service charge shall be made for any registration of
transfer or exchange (except as otherwise expressly permitted herein), but the
Company may require payment of a sum sufficient to cover any transfer tax or
similar governmental charge payable in connection therewith (other than any such
transfer tax or similar governmental charge payable upon exchanges pursuant to
Sections 2.10, 3.06 or 11.05 hereof).

          In the event of a partial redemption, the Company shall not be
required (i) to issue, register the transfer of, or exchange Notes during a
period beginning at the opening of business 15 days before the day of any
selection of Notes for redemption under Section 3.02 hereof and ending at the
close of business on the day of selection, or (ii) to exchange or register the
transfer of any Note so selected for redemption in whole or in part, except the
unredeemed portion of any Note being redeemed in part.

          Except as otherwise permitted pursuant to Section 2.01(c), so long as
a Global Note remains outstanding and is held by or on behalf of the Depositary,
transfers of a Global Note shall be limited to transfers of such Global Note in
whole, but not in part, to nominees of the Depositary or to a successor of the
Depositary or such successor's nominee.

          SECTION 2.07. Replacement Notes. If the holder of a Note claims that
                        -----------------
the Note has been lost, destroyed or wrongfully taken or if such Note is
mutilated and is surrendered to the Trustee, the Company shall issue and the
Trustee shall authenticate a replacement Note if the Trustee's and the Company's
requirements are met. If required by the Trustee or the Company, an indemnity
bond must be provided by the holder which is sufficient in the judgment of both
to protect the Company, the Trustee, any Agent or any authenticating agent from
any loss which any of them may suffer if a Note is replaced. The Company may
charge for its expenses in replacing a Note.

          In case any such mutilated, destroyed, lost or stolen Note has become
or is about to become due and payable, or is about to be purchased by the
Company pursuant to Article III hereof, the Company in its discretion may,
instead of issuing a new Note, pay or purchase such Note, as the case may be.

                                      -10-

<PAGE>

          Every replacement Note is an additional obligation of the Company.

          SECTION 2.08. Outstanding Notes. The Notes outstanding at any time are
                        -----------------
all the Notes authenticated by the Trustee except for those cancelled by it,
those delivered to it for cancellation, and those described in this Section as
not outstanding.

          If a Note is replaced, paid or purchased pursuant to Section 2.07
hereof, it ceases to be outstanding unless the Trustee receives proof
satisfactory to it that the replaced, paid or purchased Note is held by a bona
fide purchaser.

          If Notes are considered paid under Section 4.01 hereof, they cease to
be outstanding and interest on them ceases to accrue.

          A Note does not cease to be outstanding because the Company or an
Affiliate of the Company holds the Note.

          SECTION 2.09. Treasury Notes. In determining whether the Noteholders
                        --------------
of the required principal amount of Notes have concurred in any direction,
waiver or consent, Notes owned by the Company or an Affiliate of the Company
shall be considered as though they are not outstanding, except that for the
purposes of determining whether the Trustee shall be protected in relying on any
such direction, waiver or consent, only Notes which a Trust Officer of the
Trustee actually knows are so owned shall be so disregarded.

          SECTION 2.10. Temporary Notes. Until definitive Notes are ready for
                        ---------------
delivery, the Company may prepare and the Trustee shall authenticate temporary
Notes. Temporary Notes shall be substantially in the form of definitive Notes
but may have variations that the Company considers appropriate for temporary
Notes. Without unreasonable delay, the Company shall prepare and the Trustee
shall authenticate definitive Notes in exchange for temporary Notes.

          SECTION 2.11. Cancellation. The Company at any time may deliver Notes
                        ------------
to the Trustee for cancellation. The Registrar, Paying Agent and Conversion
Agent shall forward to the Trustee any Notes surrendered to them for
registration of transfer, redemption, conversion, exchange or payment. The
Trustee shall promptly cancel all Notes surrendered for registration of
transfer, redemption, conversion, exchange, payment, replacement or cancellation
and shall return all cancelled Notes to the Company. The Company may not issue
new Notes to replace Notes that it has paid or that have been delivered to the
Trustee for cancellation or that any holder has converted pursuant to Article V.
All Notes that are redeemed or purchased by the Company or any of its
Subsidiaries will forthwith be cancelled and accordingly may not be reissued or
resold.

          SECTION 2.12. Defaulted Interest. If the Company fails to make a
                        ------------------
payment of interest on the Notes, it shall pay such defaulted interest plus any
interest payable on the defaulted interest, in any lawful manner. It may pay
such defaulted interest, plus any such interest payable on it, to the Persons
who are Noteholders on a subsequent special record date. The Company shall fix
any such record date and payment date. At least 15 days before any such record
date, the Company shall mail to Noteholders a notice that states the record
date, payment date, and amount of such interest to be paid.

          SECTION 2.13. CUSIP Numbers. The Company in issuing Notes may use
                        -------------
"CUSIP" numbers (if then generally in use) in addition to serial numbers; if so,
the Trustee shall use such "CUSIP" numbers in addition to serial numbers in
notices of redemption and repurchase as a convenience to holders; provided,
                                                                  --------
however, that any such notice may state that no representation is made as to the
-------
correctness of such CUSIP number either as printed on the Notes or as contained
in any notice of a redemption or repurchase and that reliance may be placed only
on the serial or other identification numbers printed on the Notes, and any such
redemption or repurchase shall not be affected by any defect in or omission of
such CUSIP number. The Company shall promptly notify the Trustee of any change
in the CUSIP number.

                                   ARTICLE III

                                   Redemption
                                   ----------

          SECTION 3.01. Notices to Trustee. If the Company elects to redeem
                        ------------------
Notes pursuant to the optional redemption provision of Section 3.07 hereof, it
shall notify the Trustee of the redemption date and the principal amount of
Notes to be redeemed. The Company shall give each notice provided for in this
Section 3.01 at least 45 days before the redemption date.

          SECTION 3.02. Selection of Notes to be Redeemed. If less than all the
                        ---------------------------------
Notes are to be redeemed, the Trustee shall select the Notes to be redeemed by
lot provided that no Notes of $1,000 or less shall be redeemed in part. The
Trustee shall make the selection not more than 60 days and not less than 30 days
before the redemption date from Notes outstanding not previously called for
redemption. Notes and portions of them selected for redemption shall be in
amounts of $1,000 or integral multiples thereof. Provisions of this Indenture
that apply to Notes called for redemption also apply to portions of Notes called
for redemption. The Trustee shall notify the Company promptly of the Notes or
portions of Notes to be called for redemption.

          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 in whole or in
part before the mailing of the notice of redemption. Upon any redemption of less
than all the Notes, the Company and the Trustee may treat as outstanding any
Notes surrendered for conversion during the period 15 days next preceding the
mailing of a notice of redemption and 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 3.03. Notice of Redemption. At least 30 days but not more than
                        --------------------
60 days before a redemption date, the Company shall mail a notice of redemption
to each holder whose Notes are to be redeemed at such holder's registered
address.

          The notice shall identify the Notes (including CUSIP number and, if
appropriate, serial numbers) to be redeemed and shall state:

          (a) the redemption date;

                                      -12-

<PAGE>

          (b) the redemption price;

          (c) if any Note is being redeemed in part, (i) the portion of the
     principal amount of such Note to be redeemed (ii) the last date on which
     exchanges or registration of transfers of Notes may be made pursuant to
     Section 2.06 hereof and (iii) that, after the redemption date, upon
     cancellation of such Note, a new Note or Notes in principal amount equal to
     the unredeemed portion will be issued in the name of the holder thereof;

          (d) in the case of partial redemption of Notes, the aggregate
     principal amount of Notes to be redeemed and the aggregate principal amount
     of the Notes which will be outstanding after such partial redemption; and

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

          (f) that Notes called for redemption must be surrendered to the Paying
     Agent to collect the redemption price plus accrued interest;

          (g) that, unless the Company defaults in making such redemption
     payment or the Paying Agent is prohibited from making such payment pursuant
     to the terms of this Indenture, interest on Notes called for redemption
     ceases to accrue or and after the redemption date; and

          (h) the paragraph of the Notes pursuant to which the Notes called for
     redemption are being redeemed.

          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
of the Company will expire.

          At the Company's request, the Trustee shall give notice of redemption
in the Company's name and at its expense.

          SECTION 3.04. Effect of Notice of Redemption. Once notice of
                        ------------------------------
redemption is mailed, Notes called for redemption become due and payable on the
redemption date at the price set forth in the Note.

          SECTION 3.05. Deposit of Redemption Price. On or before the redemption
                        ---------------------------
date, the Company shall deposit with the Trustee or with the Paying Agent money
sufficient to pay the redemption price of and accrued interest up to but not
including the redemption date on all Notes to be redeemed on that date (subject
to the right of holders of record on the relevant record date to receive
interest due on an interest payment date) unless theretofore converted into
Common Stock pursuant to the provisions hereof. The Trustee or the Paying Agent
shall return to the Company any money not required for that purpose.

          SECTION 3.06. Notes Redeemed in Part. Upon cancellation of a Note that
                        ----------------------
is redeemed in part, the Company shall issue and the Trustee shall authenticate
for the holder at the expense of the Company a new Note equal in principal
amount to the unredeemed portion of the Note surrendered.

          SECTION 3.07. Optional Redemption. The Company may redeem all or any
                        -------------------
portion of the Notes, upon the terms and at the redemption prices set forth in
each of the Notes. Any redemption pursuant to this Section 3.07 shall be made
pursuant to the provisions of Section 3.01 through 3.06 hereof.

          SECTION 3.08. Change of Control Offer. (a) In the event that, pursuant
                        -----------------------
to Section 4.06 hereof, the Company shall commence a Change of Control Offer,
the Company shall follow the procedures in this Section 3.08.

          (b) The Change of Control Offer shall remain open for 30 calendar days
following the date of the Company Notice provided pursuant to Section 3.08(e)
(the "Commencement Date"), except to the extent that a longer period is required
by applicable law. On the date that is 45 days after the date of the Company
Notice (the "Change of Control Payment Date"), except to the extent that a
longer period is required by applicable law, the Company shall purchase the
principal amount of Notes required to be purchased pursuant to Section 4.06
hereof (the "Offer Amount").

          (c) If the Change of Control Payment Date is on or after an interest
payment record date and on or before the related interest payment date, any
accrued interest will be paid to the Person in whose name a Note is registered
at the close of business on such record date, and no additional interest will be
payable to Noteholders who tender Notes pursuant to the Change of Control Offer.

          (d) The Company shall provide the Trustee with notice of the Change of
Control Offer at least 10 Business Days before the Commencement Date.

          (e) Within 30 days after the occurrence of a Change of Control, the
Company or the Trustee (at the request and expense of the Company) shall send,
by first class mail, a notice (the "Company Notice") to each of the Noteholders,
which shall govern the terms of the Change of Control Offer and shall state:

          (i) that the Change of Control Offer is being made pursuant to this
     Section 3.08 and Section 4.06 hereof and that all Notes tendered will be
     accepted for payment;

          (ii) the Offer Amount, the purchase price (as determined in accordance
     with Section 4.06 hereof) the length of time the Change of Control Offer
     will remain open and the Change of Control Payment Date;

          (iii) that any Note or portion thereof not tendered or accepted for
     payment will continue to accrue interest;

          (iv) that, unless the Company defaults in the payment of the Change of
     Control Payment, any Note or portion thereof accepted for payment pursuant
     to the Change of Control Offer shall cease to accrue interest after the
     Change of Control Payment Date;

          (v) that Noteholders electing to have a Note or portion thereof
     purchased pursuant to any Change of Control Offer will be required to
     surrender the Note, with the

     the Note completed, to the Paying Agent at the address specified in the
     Company Notice prior to the close of business on the 30th day after the
     Commencement Date;

          (vi) that, unless the Company defaults in the payment of the Change of
     Control Payment, an election pursuant to Clause (v) above shall be
     irrevocable, and that the right of the holder to convert the Notes with
     respect to which the repurchase right is being exercised shall expire upon
     submission of such Notes; and

          (vii) that Noteholders whose Notes are being purchased only in part
     will be issued new Notes equal in principal amount to the unpurchased
     portion of the Notes surrendered, which unpurchased portion must be equal
     to $1,000 in principal amount or an integral multiple thereof.

          In addition, the notice shall contain all instructions and materials
that the Company shall reasonably deem necessary to enable such Noteholders to
tender Notes pursuant to the Change of Control Offer.

          (f) On the Change of Control Payment Date, the Company shall, to the
extent lawful, (i) irrevocably deposit with the Trustee or the Paying Agent in
immediately available funds an amount equal to the Offer Amount plus accrued
interest on such Notes or portions thereof, (ii) accept for payment the Notes or
portions thereof tendered pursuant to the Change of Control Offer, (iii) deliver
or cause to be delivered to the Trustee Notes so accepted and (iv) deliver to
the Trustee an Officers' Certificate stating such Notes or portions thereof have
been accepted for payment by the Company in accordance with the terms of this
Section 3.08. The Paying Agent shall promptly (but in any case not later than
ten (10) calendar days after the Change of Control Payment Date) mail or deliver
to each tendering Noteholder an amount equal to the purchase price of the Notes
tendered by such Noteholder plus accrued interest thereon, and the Trustee shall
promptly authenticate and mail or deliver to each such Noteholder a new Note
equal in principal amount to any unpurchased portion of the Note surrendered, if
any; provided, however, that each new Note shall be in a principal amount of
     --------  -------
$1,000 or an integral multiple thereof. Any Notes not so accepted shall be
promptly mailed or delivered by or on behalf of the Company to the holder
thereof. The Company will publicly announce the results of the Change of Control
offer on, or as soon as practicable after, the Change of Control Payment Date.

          (g) The Company will comply with the requirements of Rules 13e-4 and
14e-1 under the Exchange Act and any other securities laws and regulations
thereunder to the extent such laws and regulations are applicable in connection
with the repurchase of the Notes in connection with a Change of Control.

shall be considered paid on the date due if the Paying Agent (other than the
Company or an Affiliate of the Company) holds on that date money designated for

pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest (without regard to any
applicable grace period) at the rate borne by the Notes, compounded
semiannually.

          SECTION 4.02. Reports by Company.

     every covenant, and complied with the covenants and conditions contained in
     this Indenture and is not in default in the performance or observance of
     any of the terms, provisions and conditions hereof (or, if a Default or
     Event of Default shall have occurred, describing all such Defaults or
     Events of

                                      -16-

     knowledge no event has occurred and remains in existence by reason of which
     payments on account of the principal of or interest, if any, on the Notes
     are prohibited.

          One of the Officers signing such Officers' Certificate shall be either
the Company's principal executive officer, principal financial officer or
principal accounting officer.

          The Company will, so long as any of the Notes are outstanding, deliver
to the Trustee, forthwith upon becoming aware of any Default or Event of Default
an Officers' Certificate specifying such Default or Event of Default.

          SECTION 4.03. Stay, Extension and Usury Laws. The Company covenants
                        ------------------------------
(to the extent that it may lawfully do so) that it will not at any time insist
upon, plead, or in any manner whatsoever claim or take the benefit or advantage
of, any stay, extension or usury law wherever enacted, now or at any time
hereafter in force, which may affect the covenants or the performance of this
Indenture; and the Company (to the extent it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law, and covenants that it
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.

          SECTION 4.04. Corporate Existence. Subject to Article VII hereof, the
                        -------------------
Company will do or cause to be done all things necessary to preserve and keep in
full force and effect its corporate existence and the corporate rights (charter
and statutory), corporate licenses and corporate franchises of the Company;
provided, however, that the Company shall not be required to preserve any such
--------  -------
right, license or franchise, if the Board of Directors of the Company shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company and that the loss thereof is not adverse in any
material respect to the Noteholders.

          SECTION 4.05. Taxes. The Company shall, and shall cause each of its
                        -----
Subsidiaries to, pay prior to delinquency all taxes, assessments and
governmental levies, (i) except for such taxes, assessments and governmental
levies, the nonpayment of which is not reasonably likely to result in a material
adverse change in the financial condition, results of operations or business of
the Company and its subsidiaries, considered as a whole or (ii) except as
contested in good faith and by appropriate proceedings.

          SECTION 4.06. Change of Control. (a) Upon the occurrence of a Change
                        -----------------
of Control, each holder of Notes shall have the right, in accordance with this
Section 4.06 and Section 3.08 hereof, to require the Company to repurchase all
or any part (equal to $1,000 or an integral multiple thereof) of such holder's
Notes pursuant to the terms of Section 3.08 (the "Change of Control Offer") at a
purchase price equal to 100% of the principal amount thereof, plus accrued and
unpaid interest thereon, if any, to the Change of Control Payment Date (the
"Change of Control Payment").

                                      -17-

<PAGE>

          (b) Within 30 days following any Change of Control, the Company shall
mail to each holder the Company Notice provided by Section 3.08(e).

                                    ARTICLE V

                                   Conversion
                                   ----------

          SECTION 5.01. Conversion Privilege. A holder of a Note may convert the
                        --------------------
principal amount thereof (or any portion thereof that is an integral multiple of
$1,000) into fully paid and nonassessable shares of Common Stock of the Company
at any time prior to the close of business (New York time) on the date of the
Note's maturity at the Conversion Price in effect on the Conversion Date (the
"Conversion Price"), except that, with respect to any Note called for
redemption, such conversion right shall terminate at the close of business on
the Business Day immediately preceding the redemption date, and except that if a
Note is submitted pursuant to the exercise of a repurchase right pursuant to
Section 3.08 and Section 4.06 hereof, the right to convert such Note will expire
upon submission (unless the Company shall default in making the redemption
payment or the Change of Control Payment, as the case may be when it becomes
due, in which case the conversion right shall terminate on the date such default
is cured). The number of shares of Common Stock issuable upon conversion of a
Note is determined by dividing the principal amount of the Note converted by the
Conversion Price.

          The initial Conversion Price is stated in Section 10 of the Notes and
is subject to adjustment as provided in this Article V.

          Provisions of this Indenture that apply to conversion of all of a Note
also apply to conversion of a portion of it. A holder of Notes is not entitled
to any rights of a holder of Common Stock until such holder of Notes has
converted such Notes into Common Stock, and only to the extent that such Notes
are deemed to have been converted into Common Stock under this Article V.

          SECTION 5.02. Conversion Procedure. To convert a Note, a holder must
                        --------------------
satisfy the requirements in Section 10 of the Notes. The date on which the
holder satisfies all of those requirements is the conversion date (the
"Conversion Date"). As soon as practicable after the Conversion Date, the
Company shall deliver to the holder through the Conversion Agent a certificate
for the number of whole shares of Common Stock issuable upon the conversion and
a check for any fractional share determined pursuant to Section 5.03. The Person
in whose name the certificate is registered shall become the stockholder of
record on the Conversion Date and, as of such date, such Person's rights as a
Noteholder shall cease; provided, however, that no surrender of a Note on any
                        --------  -------
date when the stock transfer books of the Company shall be closed shall be
effective to constitute the Person entitled to receive the shares of Common
Stock upon such conversion as the stockholder of record of such shares of Common
Stock on such date, but such surrender shall be effective to constitute the
Person entitled to receive such shares of Common Stock as the stockholder of
record thereof for all purposes at the close of business on the next succeeding
day on which such stock transfer books are open; provided further, however, that
                                                 -------- -------  -------
such conversion shall be at the Conversion Price in effect on the date that such
Note shall

                                      -18-

<PAGE>

have been surrendered for conversion, as if the stock transfer books of the
Company had not been closed.

          No payment or adjustment will be made for accrued and unpaid interest
on a converted Note or for dividends or distributions on shares of Common Stock
issued upon conversion of a Note. If any holder surrenders a Note for conversion
after the close of business on the record date for the payment of an installment
of interest and prior to the opening of business on the next interest payment
date, then, notwithstanding such conversion, the interest payable on such
interest payment date shall be paid to the holder of such Note on such record
date. In such event, such Note, when surrendered for conversion, must be
accompanied by payment in funds acceptable to the Company of an amount equal to
the interest payable on such interest payment date on the portion so converted.
The interest payment with respect to a Note called for redemption on a date
during the period from the close of business on or after any record date to the
opening of business on the business day following the corresponding interest
payment date will be payable on the corresponding interest payment date to the
holder of such Note on such record date (notwithstanding the conversion of such
Note before the corresponding interest payment date) and a holder who elects to
convert need not include funds equal to the interest payment.

          If a holder converts more than one Note at the same time, the number
of whole shares of Common Stock issuable upon the conversion shall be based on
the total principal amount of Notes converted.

          Upon surrender of a Note that is converted in part, the Trustee shall
authenticate for the holder a new Note equal in principal amount to the
unconverted portion of the Note surrendered.

          SECTION 5.03. Fractional Shares. The Company will not issue fractional
                        -----------------
shares of Common Stock upon conversion of a Note. In lieu thereof, the Company
will pay an amount in cash based upon the Daily Market Price of the Common Stock
on the trading day prior to the Conversion Date. The value of a fraction of a
share of Common Stock shall be determined by multiplying the Daily Market Price
of a full share of Common Stock by a fraction equaling the fraction of the share
of Common Stock which would otherwise be issued and rounding the amount to the
nearest cent.

          SECTION 5.04. Taxes on Conversion. The issuance of certificates for
                        -------------------
shares of Common Stock upon the conversion of any Note shall be made without
charge to the converting Noteholder for such certificates or for any tax in
respect of the issuance of such certificates, and such certificates shall be
issued in the respective names of, or in such names as may be directed by, the
holder or holders of the converted Note; provided, however, that in the event
                                         --------  -------
that certificates for shares of Common Stock are to be issued in a name other
than the name of the holder of the Note converted, such Note, when surrendered
for conversion, shall be accompanied by an instrument of transfer, in form
satisfactory to the Company, duly executed by the registered holder thereof or
his duly authorized attorney; and provided, further, however, that the Company
                                  --------  -------  -------
shall not be required to pay any tax which may be payable in respect of any
transfer involved in the issuance and delivery of any such certificates in a
name other than that of the

                                      -19-

<PAGE>

holder of the converted Note, and the Company shall not be required to issue or
deliver such certificates unless or until the Person or Persons requesting the
issuance 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
or is not applicable.

          SECTION 5.05. Company To Provide Stock. The Company shall at all times
                        ------------------------
reserve and keep available, free from preemptive rights, out of its authorized
but unissued Common Stock, solely for the purpose of issuance upon conversion of
Notes as herein provided, a sufficient number of shares of Common Stock to
permit the conversion of all outstanding Notes for shares of Common Stock.

          All shares of Common Stock which may be issued upon conversion of the
Notes shall be duly authorized, validly issued, fully paid and nonassessable
when so issued.

          SECTION 5.06. Adjustment of Conversion Price. The Conversion Price
                        ------------------------------
shall be subject to adjustment from time to time as follows:

          (a) In case the Company shall (1) pay a dividend in shares of Common
Stock to holders of Common Stock, (2) make a distribution in shares of Common
Stock to holders of Common Stock, (3) subdivide its outstanding shares of Common
Stock into a greater number of shares of Common Stock or (4) combine its
outstanding shares of Common Stock into a smaller number of shares of Common
Stock, the Conversion Price in effect immediately prior to such action shall be
adjusted so that the holder of any Note thereafter surrendered for conversion
shall be entitled to receive the number of shares of Common Stock which he would
have owned immediately following such action had such Notes been converted
immediately prior thereto. Any adjustment made pursuant to this subsection (a)
shall become effective immediately after the record date in the case of a
dividend or distribution and shall become effective immediately after the
effective date in the case of a subdivision or combination.

          (b) In case the Company shall issue rights or warrants to all holders
of Common Stock entitling them (for a period commencing no earlier than the
record date for the determination of holders of Common Stock entitled to receive
such rights or warrants and expiring not more than 45 days after such record
date) to subscribe for or purchase shares of Common Stock (or securities
convertible into Common Stock) at a price per share less than the current market
price (as determined pursuant to subsection (f) below) of the Common Stock on
such record date, 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 such record date by a fraction of which the numerator shall
be the number of shares of Common Stock outstanding on such record date, plus
the number of shares of Common Stock which the aggregate offering price of the
offered shares of Common Stock (or the aggregate conversion price of the
convertible securities 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 such record date plus the number of additional shares of Common
Stock offered (or into which the convertible securities so offered are
convertible). Such adjustments shall become effective immediately after such
record date. If 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

                                      -20-

<PAGE>

date fixed for the determination of stockholders entitled to receive such rights
or warrants had not been fixed.

          (c) In case the Company shall distribute to all holders of Common
Stock shares of any class of Capital Stock of the Company other than Common
Stock, evidences of indebtedness or other assets (other than cash), or shall
distribute to all holders of Common Stock rights or warrants to subscribe for
securities or other assets (other than those securities referred to in
subsection (b) above), then in each such case 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 of such distribution by
a fraction of which the numerator shall be the current market price (determined
as provided in subsection (f) below) of the Common Stock on the record date
mentioned below less the then fair market value (as determined by the Board of
Directors, whose determination shall be conclusive evidence of such fair market
value and described in a Board Resolution) of the portion of the assets so
distributed or of such subscription rights or warrants applicable to one share
of Common Stock, and of which the denominator shall be such current market price
of the Common Stock. Such adjustment shall become effective immediately after
the record date for the determination of the holders of Common Stock entitled to
receive such distribution. Notwithstanding the foregoing, in the event that the
Company shall distribute rights or warrants to subscribe for additional shares
of the Company's Capital Stock (other than the Common Stock referred to in
subsection (b) above) ("Rights") pro rata to holders of Common Stock, the
Company may, in lieu of making any adjustment pursuant to this Section 5.06,
make proper provision so that each holder of a Note who converts such Note (or
any portion thereof) after the record date for such distribution and prior to
the expiration or redemption of the Rights shall be entitled to receive upon
such conversion, in addition to the shares of Common Stock issuable upon such
conversion (the "Conversion Shares"), a number of Rights to be determined as
follows: (i) if such conversion occurs or prior to the date for the distribution
to the holders of Rights of separate certificates evidencing such Rights (the
"Distribution Date"), the same number of Rights to which a holder of a number of
shares of Common Stock equal to the number of Conversion Shares is entitled at
the time of such conversion in accordance with the terms and provisions of and
applicable to the Rights; and (ii) if such conversion occurs after the
Distribution Date, the same number of Rights to which a holder of the number of
shares of Common Stock into which the principal amount of the Note so converted
was convertible immediately prior to the Distribution Date would have been
entitled on the Distribution Date in accordance with the terms and provisions of
and applicable to the Rights. If 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.

          (d) In case the Company shall, by dividend or otherwise, at any time
distribute to all holders of its Common Stock cash (including any distributions
of cash out of current or retained earnings of the Company) in an aggregate
amount that, together with the sum of (x) the aggregate amount of any other
distributions to all holders of its Common Stock made in cash plus (y) all
Excess Payments, in each case made within the 12 months preceding the date fixed
for determining the stockholders entitled to such distribution (the
"Distribution Record Date") and in respect of which no Conversion Price
adjustment pursuant to paragraph (e) of this Section or this paragraph (d) has
been made, exceeds 10% of the product of the current market price per

                                      -21-

<PAGE>

share (determined as provided in paragraph (f) of this Section) of the Common
Stock on the Distribution Record Date times the number of shares of Common Stock
outstanding on the Distribution Record Date (excluding shares held in the
treasury of the Company), the Conversion Price shall be reduced so that the same
shall equal the price determined by multiplying such Conversion Price in effect
immediately prior to the effectiveness of the Conversion Price reduction
contemplated by this paragraph (d) by a fraction of which the numerator shall be
(x) the current market price per share (determined as provided in paragraph (f)
of this Section) of the Common Stock on the Distribution Record Date less (y)
the amount determined by dividing the aggregate amount of such cash and other
consideration (including any Excess Payments) so distributed in excess of the
10% referred to above by the shares of Common Stock outstanding on the
Distribution Record Date, and the denominator shall be such current market price
per share (determined as provided in paragraph (f) of this Section) of the
Common Stock on the Distribution Record Date, such reduction to become effective
immediately prior to the opening of business on the day following the
Distribution Record Date.

          (e) In case a tender offer made by the Company or any Subsidiary of
the Company for all or any portion of the Common Stock shall be consummated, if
an Excess Payment is made in respect of such tender offer and the amount of such
Excess Payment, together with the sum of (x) the aggregate amount of all Excess
Payments plus (y) the aggregate amount of all distributions to all holders of
the Common Stock made in cash (specifically including distributions of cash out
of current or retained earnings), in each case made within the 12 months
preceding the expiration of such current tender offer, (the "Purchase Date"),
and as to which no adjustment pursuant to paragraph (d) of this Section or this
paragraph (e) has been made, exceeds 10% of the product of the current market
price per share (determined as provided in paragraph (f) of this Section) of the
Common Stock on the Purchase Date times the number of shares of Common Stock
outstanding (including any tendered shares but excluding any shares held in the
treasury of the Company) on the Purchase Date, the Conversion Price shall be
reduced so that the same shall equal the price determined by multiplying such
Conversion Price in effect immediately prior to the effectiveness of the
Conversion Price reduction contemplated by this paragraph (e) by a fraction of
which the numerator shall be (x) the current market price per share (determined
as provided in paragraph (f) of this Section) of the Common Stock on the
Purchase Date less (y) the amount determined by dividing the aggregate amount of
such Excess Payments and such cash distributions, if any, in excess of the 10%
amount referred to above by the shares of Common Stock outstanding on the
Purchase Date, and the denominator shall be such current market price per share
(determined as provided in paragraph (f) of this Section) of the Common Stock on
the Purchase Date, such reduction to become effective immediately prior to the
opening of business on the day following the Purchase Date.

          (f) The current market price per share of Common Stock on any date
shall be deemed to be the average of the Daily Market Prices for the shorter of
(i) 30 consecutive Trading Days ending on the last full trading day on the
exchange or market referred to in determining such Daily Market Prices prior to
the time of determination or (ii) the period commencing on the date next
succeeding the first public announcement of the issuance of such rights or such
warrants or such other distribution or such Excess Payment through such last
full trading day on the exchange or market referred to in determining such Daily
Market Prices prior to the time of determination.

                                      -22-

<PAGE>

          (g) In any case in which this Section 5.06 shall require that an
adjustment be made immediately following a record date for an event, the Company
may elect to defer, until such event, issuing to the holder of any Note
converted after such record date the shares of Common Stock and other Capital
Stock of the Company issuable upon such conversion over and above the shares of
Common Stock and other Capital Stock of the Company issuable upon such
conversion only on the basis of the Conversion Price prior to adjustment; and,
in lieu of the shares the issuance of which is so deferred, the Company shall
issue or cause its transfer agents to issue due bills or other appropriate
evidence of the right to receive such shares.

          SECTION 5.07. No Adjustment. No adjustment in the Conversion Price
                        -------------
shall be required until cumulative adjustments amount to 1% or more of the
Conversion Price as last adjusted; provided, however, that any adjustments which
                                   --------  -------
by reason of this Section 5.07 are not required to be made shall be carried
forward and taken into account in any subsequent adjustment. All calculations
under this Article V 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. No adjustment need be made for a change in the par value
or no par value of the Common Stock.

          SECTION 5.08. Other Adjustments. (a) In the event that, as a result of
                        -----------------
an adjustment made pursuant to Section 5.06 above, the holder of any Note
thereafter surrendered for conversion shall become entitled to receive any
shares of Capital Stock of the Company other than shares of its Common Stock,
thereafter the Conversion Price of such other shares so receivable upon
conversion of any Notes shall be subject to adjustment from time to time in a
manner and on terms as nearly equivalent as practicable to the provisions with
respect to Common Stock contained in this Article V.

          (b) In the event that shares of Common Stock are not delivered after
the expiration of any of the rights or warrants referred to in Section 5.06(b)
and Section 5.06(c) hereof, the conversion Price shall be readjusted to the
Conversion Price which would otherwise be in effect had the adjustment 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.

          SECTION 5.09. Adjustments for Tax Purposes. The Company may, at its
                        ----------------------------
option, make such reductions in the Conversion Price, in addition to those
required by Section 5.06 above, as the Board of Directors determines to be
advisable in order that any stock dividend, subdivision of shares, distribution
of rights to purchase stock or securities or distribution of securities
convertible into or exchangeable for stock made by the Company to its
stockholders will not be taxable to the recipients thereof.

          SECTION 5.10. Adjustments by the Company. 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 in accordance with Section 5.11, 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.

                                      -23-

<PAGE>

          SECTION 5.11. Notice of Adjustment. Whenever the Conversion Price is
                        --------------------
adjusted, the Company shall promptly mail to Noteholders at the addresses
appearing on the Registrar's books a notice of the adjustment and file with the
Trustee an Officers' Certificate briefly stating the facts requiring the
adjustment and the manner of computing it. The certificate shall be conclusive
evidence of the correctness of such adjustment.

          SECTION 5.12. Notice of Certain Transactions. In the event that:
                        ------------------------------

          (1) the Company takes any action which would require an adjustment in
the Conversion Price;

          (2) the Company takes any action that would require a supplemental
indenture pursuant to Section 5.13; or

          (3) there is a dissolution or liquidation of the Company;

a holder of a Note may wish to convert such Note into shares of Common Stock
prior to the record date for or the effective date of the transaction so that he
may receive the rights, warrants, securities or assets which a holder of shares
of Common Stock on that date may receive. Therefore, the Company shall mail to
Noteholders at the addresses appearing on the Registrar's books and the Trustee
a notice stating the proposed record or effective date, as the case may be. The
Company shall mail the notice at least 15 days before such date; however,
failure to mail such notice or any defect therein shall not affect the validity
of any transaction referred to in clause (1), (2) or (3) of this Section 5.12.

          SECTION 5.13. Effect of Reclassifications, Consolidations, Mergers or
                        -------------------------------------------------------
Sales on Conversion Privilege. If any of the following shall occur, namely: (i)
-----------------------------
any reclassification or change of outstanding shares of Common Stock issuable
upon conversion of Notes (other than a change in par value, or from par value to
no par value, or from no par value to par value, or as a result of a subdivision
or combination), (ii) any consolidation or merger to which the Company is a
party other than a merger in which the Company is the continuing corporation and
which does not result in any reclassification of, or change (other than a change
in name, or par value, or from par value to no par value, or from no par value
to par value or as a result of a subdivision or combination) in, outstanding
shares of Common Stock or (iii) any sale or conveyance of all or substantially
all of the property or business of the Company as an entirety, then the Company,
or such successor or purchasing corporation, as the case may be, shall, as a
condition precedent to such reclassification, change, consolidation, merger,
sale or conveyance, execute and deliver to the Trustee a supplemental indenture
in form satisfactory to the Trustee providing that the holder of each Note then
outstanding shall have the right to convert such Note into the kind and amount
of shares of stock and other securities and property (including cash) receivable
upon such reclassification, change, consolidation, merger, sale or conveyance by
a holder of the number of shares of Common Stock deliverable upon conversion of
such Note immediately prior to such reclassification, change, consolidation,
merger, sale or conveyance. Such supplemental indenture shall provide for
adjustments of the Conversion Price which shall be as nearly equivalent as may
be practicable to the adjustments of the Conversion Price provided for in this
Article V. The foregoing, however, shall not in any way affect the right a
holder of a Note may

                                      -24-

<PAGE>

otherwise have, pursuant to clause (ii) of the last sentence of subsection (c)
of Section 5.06, to receive Rights upon conversion of a Note. If, in the case of
any such consolidation, merger, sale or conveyance, the stock or other
securities and property (including cash) receivable thereupon by a holder of
Common Stock includes shares of stock or other securities and property of a
corporation other than the successor or purchasing corporation, as the case may
be, in such consolidation, merger, sale or conveyance, then such supplemental
indenture shall also be executed by such other corporation and shall contain
such additional provisions to protect the interests of the holders of the Notes
as the Board of Directors of the Company shall reasonably consider necessary by
reason of the foregoing. The provision of this Section 5.13 shall similarly
apply to successive consolidations, mergers, sales or conveyances.

          In the event the Company shall execute a supplemental indenture
pursuant to this Section 5.13, the Company shall promptly file with the Trustee
an Officers' Certificate briefly stating the reasons therefor, the kind or
amount of shares of stock or securities or property (including cash) receivable
by holders of the Notes upon the conversion of their Notes after any such
reclassification, change, consolidation, merger, sale or conveyance and any
adjustment to be made with respect thereto. Neither the Trustee nor any
Conversion Agent shall have any duty whatsoever to determine whether a
supplemental indenture under this Section 5.13 is required or what the
provisions of such supplemental indenture should be.

          SECTION 5.14. Trustee's Disclaimer. The Trustee has no duty to
                        --------------------
determine when an adjustment under this Article V should be made, how it should
be made or what such adjustment should be, but may accept as conclusive evidence
of the correctness of any such adjustment, and shall be protected in relying
upon the Officers' Certificate with respect thereto which the Company is
obligated to file with the Trustee pursuant to Section 5.11. The Trustee makes
no representation as to the validity or value of any securities or assets issued
upon conversion of Notes, and the Trustee shall not be responsible for the
Company's failure to comply with any provisions of this Article V.

          The Trustee shall not be under any responsibility to determine the
correctness of any provisions contained in any supplemental indenture executed
pursuant to Section 5.13, but may accept as conclusive evidence of the
correctness thereof, and shall be protected in relying upon, the Officers'
Certificate with respect thereto which the Company is obligated to file with the
Trustee pursuant to Section 5.13.

                                   ARTICLE VI

                                  Subordination
                                  -------------

          SECTION 6.01. Agreement To Subordinate. The Company, for itself and
                        ------------------------
its successors, and each Noteholder, by his acceptance of Notes, agree that the
payment of the principal of or interest or any other amounts due on the Notes is
subordinated in right of payment, to the extent and in the manner stated in this
Article VI, to the prior payment in full of all existing and future Senior Debt.

                                      -25-

<PAGE>

          SECTION 6.02. No Payment on Notes if Senior Debt in Default. Anything
                        ---------------------------------------------
in this Indenture to the contrary notwithstanding, no payment on account of
principal, or interest on, or redemption, repurchase or other amounts due on the
Notes, and no redemption, purchase, or other acquisition of the Notes, shall be
made by or on behalf of the Company (i) unless full payment of amounts then due
for principal and interest or other amounts then due on all Senior Debt has been
made or duly provided for pursuant to the terms of the instrument governing such
Senior Debt or (ii) if there shall have occurred an event of default (other than
a default in the payment of principal, sinking funds or interest or other
amounts) with respect to any Senior Debt, as defined therein or in the
instrument under which the same is outstanding, permitting the holders thereof
to accelerate the maturity thereof and written notice of such occurrence shall
have been given to the Company and to the Trustee under this Indenture by any
holder or holders of such Senior Debt and such event of default shall not have
been cured or waived or shall not have ceased to exist.

          In the event that, notwithstanding the provisions of this Section
6.02, payments are made by or on behalf of the Company in contravention of the
provisions of this Section 6.02, such payments shall be held by the Trustee, any
Paying Agent or the holders, as applicable, in trust for the benefit of, and
shall be paid over to and delivered to, the Representative of the holders of
Senior Debt or the trustee under the indenture or other agreement (if any),
pursuant to which any instruments evidencing any Senior Debt may have been
issued for application to the payment of all Senior Debt ratably according to
the aggregate amounts remaining unpaid to the extent necessary to pay all Senior
Debt in full in accordance with the terms of such Senior Debt, after giving
effect to any concurrent payment or distribution to or for the holders of Senior
Debt.

          The Company shall give prompt written notice to the Trustee and any
Paying Agent of any default or event of default under any Senior Debt or under
any agreement pursuant to which any Senior Debt may have been issued.

          SECTION 6.03. Distribution on Acceleration of Notes; Dissolution and
                        ------------------------------------------------------
Reorganization; Subrogation of Notes. (a) If the Notes are declared due and
------------------------------------
payable because of the occurrence of an Event of Default, the Company shall give
prompt written notice to the holders of all Senior Debt or to the trustee(s) or
other Representative for such Senior Debt of such acceleration. The Company may
not pay the principal of, interest or any other amounts due on the Notes until
five days after such holders or trustee(s) of Senior Debt receive such notice
and, thereafter, the Company may pay the principal of, interest or any other
amounts due on the Notes only if the provisions of this Article VI permit such
payment.

          (b) Upon (i) any acceleration of the principal amount due on the Notes
because of an Event of Default or (ii) any distribution of assets of the Company
upon any dissolution, winding up, liquidation or reorganization of the Company
(whether in bankruptcy, insolvency or receivership proceedings or upon an
assignment for the benefit of creditors or any other dissolution, winding up,
liquidation or reorganization of the Company):

               (1) the holders of all Senior Debt shall first be entitled to
receive payment in full of the principal thereof, the interest thereon and any
other amounts due thereon

                                      -26-

<PAGE>

before the Noteholders are entitled to receive payment on account of the
principal of or interest on or any other amounts due on the Notes;

               (2) any payment or distribution of assets of the Company of any
kind or character, whether in cash, property or securities (other than
securities 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 subordinate, at least to the extent
provided in this Article with respect to the Notes, to the payment in full
without diminution or modification by such plan of all Senior Debt), to which
the holders or the Trustee would be entitled except for the provisions of this
Article, shall be paid by the liquidating trustee or agent or other Person
making such a payment or distribution, directly to the holders of Senior Debt
(or their Representatives(s) or trustee(s) acting on their behalf), ratably
according to the aggregate amounts remaining unpaid on account of the principal
of, interest and other amounts due on the Senior Debt held or represented by
each, to the extent necessary to make payment in full of all Senior Debt
remaining unpaid, after giving effect to any concurrent payment or distribution
to the holders of such Senior Debt; and

               (3) in the event that, notwithstanding the foregoing, any payment
or distribution of assets of the Company of any kind or character, whether in
cash, property or securities (other than securities 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
subordinate, at least to the extent provided in this Article with respect to the
Notes, to the payment in full without diminution or modification by such plan of
Senior Debt), shall be received by the Trustee or the Noteholders before all
Senior Debt is paid in full, such payment or distribution shall be held in trust
for the benefit of, and be paid over to upon written request by a holder of the
Senior Debt, the holders of the Senior Debt remaining unpaid (or their
Representatives) or trustee(s) acting on their behalf, ratably as aforesaid, for
application to the payment of such Senior Debt until all such Senior Debt shall
have been paid in full, after giving effect to any concurrent payment or
distribution to the holders of such Senior Debt.

          Subject to the payment in full of all Senior Debt, the Noteholders
shall be subrogated to the rights of the holders of Senior Debt to receive
payments or distributions of cash, property or securities of the Company
applicable to the Senior Debt until the principal of and interest on the Notes
shall be paid in full and, for purposes of such subrogation, no such payments or
distributions to the holders of Senior Debt of cash, property or securities
which otherwise would have been payable or distributable to Noteholders shall,
as between the Company, its creditors other than the holders of Senior Debt, and
the Noteholders, be deemed to be a payment by the Company to or on account of
the Senior Debt, it being understood that the provisions of this Article are and
are intended solely for the purpose of defining the relative rights of the
Noteholders, on the one hand, and the holders of Senior Debt, on the other hand.

          Nothing contained in this Article or elsewhere in this Indenture or in
the Notes is intended to or shall (i) impair, as between the Company and its
creditors other than the holders of Senior Debt, the obligation of the Company,
which is absolute and unconditional, to pay to the Noteholders the principal of
and interest on the Notes as and when the same shall become due and payable in
accordance with the terms of the Notes, (ii) affect the relative rights of the

                                      -27-

<PAGE>

Noteholders and creditors of the Company other than holders of Senior Debt or,
as between the Company and the Trustee, the obligations of the Company to the
Trustee, or (iii) prevent the Trustee or the holders from exercising all
remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, under this Article of the holders of
Senior Debt in respect of cash, property and securities of the Company received
upon the exercise of any such remedy.

          Upon distribution of assets of the Company referred to in this
Article, the Trustee, subject to the provisions of Section 9.01 hereof, and the
Noteholders shall be entitled to rely upon a certificate of the liquidating
trustee or agent or other Person making any distribution to the Trustee or to
the Noteholders for the purpose of ascertaining the Persons entitled to
participate in such distribution, the holders of the Senior Debt and other
indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article. The Trustee, however, shall not be deemed to owe any fiduciary
duty to the holders of Senior Debt. Nothing contained in this Article or
elsewhere in this Indenture, or in any of the Notes, shall prevent the good
faith application by the Trustee of any moneys which were deposited with it
hereunder, prior to its receipt of written notice of facts which would prohibit
such application, for the purpose of the payment of or on account of the
principal of or interest on the Notes unless, prior to the date on which such
application is made by the Trustee, the Trustee shall have received at the
address specified in Section 12.09 hereof written notice in accordance with
Section 6.03(d) hereof of the facts which would prohibit the making of such
application.

          (c) The provisions of this Article shall not be applicable to any
cash, properties or securities received by the Trustee or by any holder when
received as a holder of Senior Debt and nothing in Section 9.11 hereof or
elsewhere in this Indenture shall deprive the Trustee or such holder of any of
its rights as such holder.

          (d) The Company shall give prompt written notice to the Trustee of any
fact known to the Company which would prohibit the making of any payment of
money to or by the Trustee in respect of the Notes pursuant to the provisions of
this Article. Notwithstanding the provisions of this Article or any other
provisions of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any fact which would prohibit the making of any payment of
moneys to or by the Trustee in respect of the Notes pursuant to the provisions
in this Article, unless and until three Business Days after the Trustee shall
have received written notice thereof at the address specified in Section 12.09
hereof from the Company or any holder or holders of Senior Debt or from any
trustee therefor; and, prior to the receipt of any such written notice, the
Trustee, subject to the provisions of Section 9.01 hereof, shall be entitled in
all respects conclusively to assume that no such facts exist; provided, however,
                                                              --------  -------
that if on a date not less than three Business Days immediately preceding the
date upon which, by the terms hereof, any such moneys may become payable for any
purpose (including, without limitation, the principal of or interest on any
Note), the Trustee shall not have received with respect to such moneys the
notice provided for in this Section 6.03(d), then anything herein contained to
the contrary notwithstanding, the Trustee shall have full power and authority to
receive such moneys 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.

                                      -28-

<PAGE>

          The Trustee shall be entitled to conclusively rely on the delivery to
it of a written notice by a Person representing himself to be a holder of Senior
Debt (or a trustee on behalf of such holder) to establish that such notice has
been given by a holder of Senior Debt (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 Debt to participate in any payment or distribution pursuant to this
Article, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Debt 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, 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; nor shall the Trustee be charged
with knowledge of the curing or waiving of any default of the character
specified in Section 6.02 hereof or that any event or any condition preventing
any payment in respect of the Notes shall have ceased to exist, unless and until
the Trustee shall have received written notice to such effect.

          (e) The provisions of this Section 6.03 applicable to the Trustee
shall (unless the context requires otherwise) also apply to any Paying Agent for
the Company.

          SECTION 6.04. Reliance by Senior Debt on Subordination Provisions.
                        ---------------------------------------------------
Each Noteholder by his acceptance thereof acknowledges and agrees that the
foregoing subordination provisions are, and are intended to be, an inducement
and a consideration for each holder of any Senior Debt, whether such Senior Debt
was created or acquired before or after the issuance of the Notes, to acquire
and continue to hold, or to continue to hold, such Senior Debt, and such holder
of Senior Debt shall be deemed conclusively to have relied on such subordination
provisions in acquiring and continuing to hold, or in continuing to hold, such
Senior Debt. Notice of any default in the payment of any Senior Debt, except as
expressly stated in this Article, and notice of acceptance of the provisions
hereof are hereby expressly waived. Except as otherwise expressly provided
herein, no waiver, forbearance or release by any holder of Senior Debt under
such Senior Debt or under this Article shall constitute a release of any of the
obligations or liabilities of the Trustee or holders of the Notes provided in
this Article.

          SECTION 6.05. No Waiver of Subordination Provisions. Except as
                        -------------------------------------
otherwise expressly provided herein, no right of any present or future holder of
any Senior Debt to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Company or by any act or failure to act, in good faith, by any such holder,
or by any noncompliance by the Company with the terms, provisions and covenants
of this Indenture, regardless of any knowledge thereof any such holder may have
or be otherwise charged with.

          Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Debt may, at any time and from time to time, without the
consent of, or notice to, the Trustee or the holders of the Notes, without
incurring responsibility to the holders of the Notes and without impairing or
releasing the subordination provided in this Article VI or the obligations
hereunder of the holders of the Notes to the holders of Senior Debt, do any one
or more of the following: (i) change the manner, place or terms of payment of,
or renew or alter,

                                      -29-

<PAGE>

Senior Debt, or otherwise amend or supplement in any manner Senior Debt or any
instrument evidencing the same or any agreement under which Senior Debt is
outstanding; (ii) sell, exchange, release or otherwise dispose of any property
pledged, mortgaged or otherwise securing Senior Debt; (iii) release any Person
liable in any manner for the collection of Senior Debt; and (iv) exercise or
refrain from exercising any rights against the Company or any other Person.

          SECTION 6.06. Trustee's Relation to Senior Debt. The Trustee in its
                        ---------------------------------
individual capacity shall be entitled to all the rights set forth in this
Article in respect of any Senior Debt at any time held by it, to the same extent
as any holder of Senior Debt, and nothing in Section 9.11 hereof or elsewhere in
this Indenture shall deprive the Trustee of any of its rights as such holder.

          With respect to the holders of Senior Debt, the Trustee undertakes to
perform or to observe only such of its covenants and obligations, as are
specifically set forth in this Article, and no implied covenants or obligations
with respect to the holders of Senior Debt shall be read into this Indenture
against the Trustee. The Trustee shall not owe any fiduciary duty to the holders
of Senior Debt but shall have only such obligations to such holders as are
expressly set forth in this Article.

          Each Noteholder by his acceptance thereof authorizes and directs the
Trustee on his behalf to take such action as may be necessary or appropriate to
effectuate the subordination provided in this Article and appoints the Trustee
his attorney-in-fact for any and all such purposes, including, in the event of
any dissolution, winding up or liquidation or reorganization under any
applicable bankruptcy law of the Company (whether in bankruptcy, insolvency or
receivership proceedings or otherwise), the timely filing of a claim for the
unpaid balance of such Noteholder's Notes in the form required in such
proceedings and the causing of such claim to be approved. If the Trustee does
not file a claim or proof of debt in the form required in such proceedings prior
to 30 days before the expiration of the time to file such claims or proofs, then
any holder or holders of Senior Debt or their representative or representatives
shall have the right to demand, sue for, collect, receive and receipt for the
payments and distributions in respect of the Notes which are required to be paid
or delivered to the holders of Senior Debt as provided in this Article and to
file and prove all claims therefor and to take all such other action in the name
of the holders or otherwise, as such holders of Senior Debt or representative
thereof may determine to be necessary or appropriate for the enforcement of the
provisions of this Article.

          SECTION 6.07. Other Provisions Subject Hereto. Expect as expressly
                        -------------------------------
stated in this Article, notwithstanding anything contained in this Indenture to
the contrary, all the provisions of this Indenture and the Notes are subject to
the provisions of this Article. However, nothing in this Article shall apply to
or adversely affect the claims of, or payment to, the Trustee pursuant to
Section 9.07. Notwithstanding the foregoing, the failure to make a payment on
account of principal of or interest on the Notes by reason of any provision of
this Article VI shall not be construed as preventing the occurrence of an Event
of Default under Section 8.01.

          SECTION 7.01. Company May Consolidate, Etc., Only on Certain Terms.
                        ----------------------------------------------------
The Company may not consolidate or merge with or into any Person (whether or not
the Company is the surviving corporation), or sell, assign, transfer, lease,
convey or otherwise dispose of all or substantially all of its properties or
assets unless:

          (a) the Company is the surviving or continuing corporation or the
     Person formed by or surviving any such consolidation or merger (if other
     than the Company) or the Person which acquires by sale, assignment,
     transfer, lease, conveyance or other disposition the properties and assets
     of the Company, is a corporation organized or existing under the laws of
     the United States, any state thereof or the District of Columbia;

          (b) the entity or Person formed by or surviving any such consolidation
     or merger (if other than the Company) assumes all the obligations of the
     Company, pursuant to a supplemental indenture in a form reasonably
     satisfactory to the Trustee, under the Notes and this Indenture;

          (c) such sale, assignment, transfer, lease, conveyance or other
     disposition of all or substantially all of the Company's properties or
     assets shall be as an entirety or virtually as an entirety to one Person
     and such Person shall have assumed all the obligations of the Company,
     pursuant to a supplemental indenture in a form reasonably satisfactory to
     the Trustee, under the Notes and this Indenture;

          (d) immediately after such transaction no Default or Event of Default
     exists; and

          (e) the Company or such Person shall have delivered to the Trustee an
     Officers' Certificate and an Opinion of Counsel, each stating that such
     transaction and the supplemental indenture comply with this Indenture and
     that all conditions precedent in this Indenture relating to such
     transaction have been satisfied.

          SECTION 7.02. Successor Corporation Substituted. Upon any
                        ---------------------------------
consolidation or merger, or any sale, assignment, transfer, lease, conveyance or
other disposition of all or substantially all of the assets of the Company in
accordance with Section 7.01 hereof, the successor corporation formed by such
consolidation or into or with which the Company is merged or to which such sale,
assignment, transfer, lease, conveyance or other disposition is made shall
succeed to, and be substituted for and may exercise every right and power of,
the Company under this Indenture with the same effect as if such successor
Person has been named as the Company herein; provided, however, that the
                                             --------  -------
predecessor Company in the case of a sale, assignment, transfer, lease,
conveyance or other disposition shall not be released from the obligations under

                              ---------------------

          SECTION 8.01. Events of Default. An "Event of Default" occurs if:
                        -----------------

          (a) the Company defaults in the payment of interest on any Note when
     the same becomes due and payable, whether or not such payments shall be
     prohibited by Article VI, and the Default continues for a period of 30 days
     after such date;

          (b) the Company defaults in the payment of the principal on any Note
     when the same becomes due and payable at maturity, upon redemption, upon
     required repurchase or otherwise, whether or not such payment shall be
     prohibited by Article VI;

          (c) failure by the Company to make a payment with respect to
     repurchase of Notes in accordance with the provisions contained in Section
     4.06 hereof, whether or not such purchase shall be prohibited by Article
     VI;

          (d) the Company fails to observe or perform any other covenant or
     agreement contained in this Indenture or the Notes, required by it to be
     performed, and the Default continues for a period of 60 days after the
     receipt of written notice from the Trustee to the Company or from the
     holders of 25% in aggregate principal amount of the then outstanding Notes
     to the Company and the Trustee stating that such notice is a "Notice of
     Default";

          (e) there is a default under any mortgage, indenture or instrument
     under which there may be issued or by which there may be secured or
     evidenced any indebtedness for money borrowed by the Company or any
     Subsidiary of the Company (or the payment of which is guaranteed by the
     Company or any Subsidiary of the Company), whether such indebtedness or
     guarantee now exists or is created after the Issuance Date, which default
     (i) is caused by a failure to pay when due principal of or interest on such
     indebtedness within the grace period provided for in such indebtedness
     (which failure continues beyond any applicable grace period) (a "Payment
     Default") or (ii) results in the acceleration of such indebtedness prior to
     its express maturity and, in each case, the principal amount of any such
     indebtedness, together with the principal amount of any other such
     indebtedness under which there has been a Payment Default which is
     continuing or the maturity of which has been so accelerated, aggregates $15
     million or more; provided, however, that no such default by a Subsidiary
                      --------  -------
     shall be covered by this clause (e) unless such Subsidiary alone or
     together with all other Subsidiaries which are then in default as described
     by subclauses (i) or (ii) in this clause (e), would, in the aggregate,
     constitute a Material Subsidiary;

          (f) failure by the Company or any Subsidiary of the Company to pay
     final judgments (other than any judgment as to which a reputable insurance
     company has accepted full liability) aggregating in excess of $15 million,
     which judgments are not stayed within 60 days after their entry; provided,
                                                                      --------
     however, that no such default by a
     -------

                                      -32-

<PAGE>

     Subsidiary shall be covered by this subsection (f) unless such Subsidiary
     alone or together with all other Subsidiaries which then have such final
     judgments outstanding, would, in the aggregate, constitute a Material
     Subsidiary;

          (g) the Company or any Material Subsidiary pursuant to or within the
     meaning of any Bankruptcy Law: (i) commences a voluntary case, (ii)
     consents to the entry of an order for relief against it in an involuntary
     case in which it is the debtor, (iii) consents to the appointment of a
     Custodian of it or for all or substantially all of its property, (iv) makes
     a general assignment for the benefit of its creditors, or (v) makes the
     admission in writing that it generally is unable to pay its debts as the
     same become due; or

          (h) a court of competent jurisdiction enters an order or decree under
     any Bankruptcy Law that: (i) is for relief against the Company or any
     Material Subsidiary of the Company in an involuntary case, (ii) appoints a
     Custodian of the Company or any Material Subsidiary of the Company or for
     all or substantially all of its property, and the order or decree remains
     unstayed and in effect for 60 days, or (iii) orders the liquidation of the
     Company or any Material Subsidiary of the Company, and the order or decree
     remains unstayed and in effect for 60 days.

          The term "Bankruptcy Law" means Title 11, U.S. Code or any similar
federal or state law for the relief of debtors. The term "Custodian" means any
receiver, trustee, assignee, liquidator or similar official under any Bankruptcy
Law.

          SECTION 8.02. Acceleration. If any Event of Default (other than an
                        ------------
Event of Default specified in clauses (g) and (h) of Section 8.01 hereof) occurs
and is continuing, the Trustee by notice to the Company, or the Noteholders of
at least 25% in principal amount of the then outstanding Notes by notice to the
Company and the Trustee, may declare all the Notes to be due and payable. Upon
such declaration, the principal of and accrued and unpaid interest on the Notes
shall be due and payable immediately. If an Event of Default specified in clause
(g) or (h) of Section 8.01 hereof occurs, the principal of and accrued and
unpaid interest on the Notes shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Noteholder. In the event of a declaration of acceleration hereunder because an
Event of Default set forth in paragraph (e) of Section 8.01 has occurred and is
continuing, such declaration of acceleration will be automatically annulled if
the holders of the indebtedness which is the subject of such Event of Default
have waived such Payment Default or rescinded their declaration of acceleration
in respect of such indebtedness or if such Payment Default has been cured within
30 days thereof and no other Event of Default has occurred during such 30-day
period which has not been cured or waived. The Noteholders of a majority in
aggregate principal amount of the then outstanding Notes, by written notice to
the Trustee, may rescind and annul an acceleration and its consequences if the
rescission would not conflict with any judgment or decree and if all Events of
Default have been cured or waived except nonpayment of principal or interest
that has become due solely because of the acceleration.

<PAGE>

          SECTION 8.03. Other Remedies. If an Event of Default occurs and is
                        --------------
continuing, the Trustee may pursue any available remedy to collect the payment
of principal or interest on the Notes or to enforce the performance of any
provision of the Notes or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Notes or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Noteholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

          SECTION 8.04. Waiver of Past Defaults. Subject to Section 11.02, the
                        -----------------------
Noteholders of a majority in aggregate principal amount of the then outstanding
Notes by notice to the Trustee may on behalf of all the holders waive an
existing Default or Event of Default and its consequences. When a Default or
Event of Default is waived, it is cured and ceases; but no such waiver shall
extend to any subsequent or other Default or impair any right consequent
thereon.

          SECTION 8.05. Control by Majority. The Noteholders of a majority in
                        -------------------
principal amount of the then outstanding Notes may direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on it. However, the Trustee may refuse
to follow any direction that conflicts with law or this Indenture, is unduly
prejudicial to the rights of other Noteholders, or would involve the Trustee in
personal liability.

          SECTION 8.06. Limitation on Suits. A Noteholder may pursue a remedy
                        -------------------
with respect to this Indenture or the Notes only if:

          (a) the Noteholder gives to the Trustee notice of a continuing Event
     of Default;

          (b) the Noteholders of at least 25% in principal amount of the then
     outstanding Notes make a request to the Trustee to pursue the remedy;

          (c) such Noteholder or Noteholders offer to the Trustee indemnity
     satisfactory to the Trustee against any loss, liability or expense;

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

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

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

          SECTION 8.07. Rights of Noteholders To Receive Payment.
                        ----------------------------------------
Notwithstanding any other provision of this Indenture, the right of any
Noteholder to convert such Noteholder's Note and to receive payment of principal
and interest on such Noteholder's Note, on or after the respective due dates
expressed in such Note, or to bring suit for the enforcement of any such payment
on or after such respective dates, shall not be impaired or affected without the
consent of the Noteholder made pursuant to this Section.

          SECTION 8.08. Collection Suit by Trustee. If an Event of Default
                        --------------------------
specified in Section 8.01(a) or (b) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount of principal and interest remaining unpaid on the
Notes and interest on overdue principal and interest and such further amount as
shall be sufficient to cover the costs and, to the extent lawful, expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

          SECTION 8.09. Trustee May File Proofs of Claim. The Trustee may file
                        --------------------------------
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Noteholders allowed
in any judicial proceedings relative to the Company, its creditors omits
property. Nothing contained herein shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Noteholder any plan
of reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Noteholder thereof, or to authorize the Trustee to vote in
respect of the claim of any Noteholder in any such proceeding.

          SECTION 8.10. Priorities. If the Trustee collects any money pursuant
                        ----------
to this Article, it shall pay out the money in the following order:

          First: to the Trustee for amounts due under Section 9.07 hereof;
          -----

          Second: to the holders of Senior Debt to the extent required by
          ------
     Article VI;

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

          Fourth: to the Company.
          ------

          Except as otherwise provided in Section 2.12 hereof, the Trustee may
fix a record date and payment date for any payment to Noteholders made pursuant
to this Section.

          SECTION 8.11. Undertaking for Costs. In any suit for the enforcement
                        ---------------------
of any right or remedy under this Indenture or in any suit against the Trustee
for any action taken or omitted by it as a Trustee, a court in its discretion
may require the filing by any party litigant in the suit of an undertaking to
pay the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees and expenses, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section does not apply to a
suit by the Trustee, a suit by a holder pursuant to

                                      -35-

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.

          (b) Except during the continuance of an Event of Default: (i) the
Trustee need perform only those duties that are specifically set forth in this
Indenture and no others and (ii) in the absence of bad faith on its part, the
Trustee may conclusively rely, as to the truth of the statements and the

furnished to the Trustee and conforming to the requirements of this Indenture.
However, in the case of any such certificates or opinions which by any provision
hereof are specifically required to be furnished to the Trustee, the Trustee
shall examine the certificates and opinions to determine whether or not they
conform to the requirements of this Indenture.

          (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that: (i) this paragraph does not limit the effect of

8.05 hereof.

          (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section 9.01. No
provision of this Indenture shall require the Trustee to expend or risk its own

or power unless it receives indemnity satisfactory to it against any loss,
liability or expense.

          (f) The Trustee shall not be liable for interest on any money received

                        -----------------

matter stated in the document.

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

          (c) The Trustee shall not be liable for any action that it takes or
omits to take in good faith, without negligence or willful misconduct, and that
it reasonably believes to be authorized or within its rights or powers.

          (d) The Trustee shall not be charged with knowledge of any Event of
Default under subsection (c), (d), (e) or (f) of Section 8.01 or of the identity
of any Material Subsidiary unless either (1) a Trust Officer assigned to its
corporate trust department shall have actual knowledge thereof, or (2) the
Trustee shall have received notice thereof in accordance with Section 12.02
hereof from the Company or any holder.

          (e) The Trustee may consult with counsel of its selection and the
advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in reliance thereon.

          (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 with due care by it
hereunder.

          SECTION 9.03. Individual Rights of Trustee. The Trustee in its
                        ----------------------------
individual or any other capacity may become the owner or pledgee of Notes and
may otherwise deal with the Company or an Affiliate of the Company with the same
rights it would have if it were not Trustee. Any Agent may do the same with like
rights. However, the Trustee is subject to Sections 9.10 and 9.11 hereof.

          SECTION 9.04. Trustee's Disclaimer. The Trustee makes no
                        --------------------
representation as to the validity or adequacy of this Indenture or the Notes, it
shall not be accountable for the Company's use of the proceeds from any Notes
authenticated and delivered by the Trustee in conformity with the provisions of
this Indenture, and it shall not be responsible for any statement of the Company
in the Indenture or any statement in the Notes other than its authentication.

          SECTION 9.05. Notice of Defaults. If a Default or Event of Default
                        ------------------
occurs and is continuing and if it is actually known to the Trustee, the Trustee
shall mail to Noteholders a notice of the Default or Event of Default within 90
days after it occurs. Except in the case of a Default or Event of Default in
payment of principal or interest on any Note, the Trustee may withhold the
notice if and so long as a committee of its Trust officers in good faith
determines that withholding the notice is in the interests of Noteholders.

          SECTION 9.06. Reports by Trustee to Noteholders. Within 60 days after
                        ---------------------------------
the reporting date stated in Section 12.09, the Trustee shall mail to
Noteholders a brief report dated as of such reporting date that complies with
TIA Section 313(a) if and to the extent required by such Section

                                      -37-

<PAGE>

313(a). The Trustee also shall comply with TIA Section 313(b)(2). The Trustee
shall also transmit by mail all reports as required by TIA Section 313(c).

          A copy of each report at the time of its mailing to Noteholders shall
be filed with the SEC and each stock exchange on which the Notes are listed. The
Company shall promptly notify the Trustee when the Notes are listed on any stock
exchange.

          SECTION 9.07. Compensation and Indemnity. The Company shall pay to the
                        --------------------------
Trustee from time to time such compensation for its services hereunder as shall
be agreed to in writing between the Company and the Trustee. The Trustee's
compensation shall not be limited by any law on compensation of a trustee of an
express trust. The Company shall reimburse the Trustee upon request for all
reasonable and duly documented disbursements, expenses and advances incurred or
made by it. Such disbursements and expenses may include the reasonable and duly
documented disbursements, compensation and expenses of the Trustee's agents and
counsel.

          The Company shall indemnify each of the Trustee or any predecessor
Trustee and its officers, directors, employees and all other agents against any
and all loss, damage, claim, expense, including taxes (other than taxes based on
the income of the Trustee) or liability incurred by it except as set forth in
the next paragraph. The Trustee shall notify the Company promptly of any claim
for which it may seek indemnity. The Company shall defend the claim and the
Trustee shall cooperate in the defense. The Trustee may have separate counsel
and the Company shall pay the reasonable and duly documented fees, disbursements
and expenses of such counsel. The Company need not pay for any settlement made
without its consent, which consent shall not be unreasonably withheld.

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

          To secure the Company's payment obligations in this Section, the
Trustee shall have a lien prior to the Notes on all money or property held or
collected by the Trustee, except money or property held in trust to pay
principal and interest on particular Notes.

          When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 8.01(g) or (h) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

          The provisions of this Section 9.07 shall survive the termination of
this Indenture, as provided by Section 10.01 hereof.

          SECTION 9.08. Replacement of Trustee. A resignation or removal of the
                        ----------------------
Trustee and appointment of a successor Trustee shall become effective only upon
the successor Trustee's acceptance of appointment as provided in this Section.

          The Trustee may resign by so notifying the Company. The Noteholders of
a majority in principal amount of the then outstanding Notes may remove the
Trustee by so notifying the Trustee and the Company. The Company may remove the
Trustee if:

                                      -38-

     Trustee's duty to resign is stayed as provided in TIA Section 310(b);

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

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

          (d) the Trustee becomes incapable of acting.

          If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the
Noteholders of a majority in principal amount of the then outstanding Notes may
appoint a successor Trustee to replace the successor Trustee appointed by the
Company.

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

          If the Trustee fails to comply with Section 9.10 hereof, unless the
Trustee's duty to resign is stayed as provided in TIA Section 310(b), any
Noteholder who has been a bona fide holder of a Note for at least six months may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, the
Company shall promptly pay all amounts due and payable to the retiring Trustee
pursuant to Section 9.07 hereof and the successor Trustee shall have all the
rights, powers and duties of the Trustee under this Indenture. The successor
Trustee shall mail a notice of its succession to Noteholders. The retiring
Trustee shall promptly transfer all property held by it as Trustee to the
successor Trustee, subject to the lien provided for in Section 9.07 hereof.
Notwithstanding replacement of the Trustee pursuant to this Section 9.08, the
Company's obligations under Section 9.07 hereof shall continue for the benefit
of the retiring trustee with respect to expenses and liabilities incurred by it
prior to such replacement.

          SECTION 9.09. Successor Trustee by Merger, Etc. If the Trustee
                        --------------------------------
consolidates, merges or converts into, or transfers all or substantially all of
its corporate trust business to, another corporation, the successor corporation
without any further act shall be the successor Trustee.

          SECTION 9.10. Eligibility; Disqualification. This Indenture shall
                        -----------------------------
always have a Trustee who satisfies the requirements of TIA Section 310(a)(1)
and (5). The Trustee shall always have a combined capital and surplus as stated
in Section 12.09 hereof. The Trustee is subject to TIA Section 310(b).

                                      -39-

          SECTION 9.11. Preferential Collection of Claims Against Company. The
                        -------------------------------------------------
Trustee is subject to TIA Section 311(a), excluding any creditor relationship
listed in TIA Section 311(b). A Trustee who has resigned or been removed shall
be subject to TIA Section 311(a) to the extent indicated therein.

          SECTION 9.12. Sections Applicable to Registrar, Paying Agent and
                        --------------------------------------------------
Conversion Agent. The term "Trustee" as used in Sections 9.01, 9.02, 9.03, 9.04
----------------
and 9.07 hereof shall (unless the context requires otherwise) be construed as
extending to and including the Trustee acting in its capacity, if any, as
Registrar, Paying Agent and Conversion Agent.

                             ----------------------

          SECTION 10.01. Termination of Company's Obligations. This Indenture
                         ------------------------------------
shall cease to be of further effect (except that obligations under Sections 9.07
and 10.02 hereof shall survive) when all outstanding Notes theretofore
authenticated and issued have been delivered to the Trustee for cancellation and
the Company has paid all sums payable hereunder.

          Thereupon, the Trustee, upon written request of the Company, shall
acknowledge in writing the discharge of the Company's obligations under this
Indenture, except for those surviving obligations specified above.

          SECTION 10.02. Repayment to Company. The Trustee and the Paying Agent
                         --------------------
shall promptly pay to the Company upon written request any excess money or
securities held by them at any time.

          The Trustee and the Paying Agent shall pay to the Company upon written
request any money held by them for the payment of principal or interest that
remains unclaimed for two years after the date upon which such payment shall
have become due; provided, however, that the Company shall have first caused
                 --------  -------
notice of such payment to the Company to be mailed to each Noteholder entitled
thereto no less than 30 days prior to such payment. After payment to the
Company, the Trustee and the Paying Agent shall have no further liability with
respect to such money and Noteholders entitled to the money must look to the
Company for payment as general creditors unless any applicable abandoned
property law designates another Person.

                       Amendments, Supplements and Waivers
                       -----------------------------------

          SECTION 11.01. Without Consent of Noteholders. The Company and the
                         ------------------------------
Trustee may amend or supplement this Indenture or the Notes without the consent
of any Noteholder:

          (a) to cure any ambiguity, defect or inconsistency;

          (b) to comply with Sections 5.13 and 7.01 hereof;

                                      -40-

<PAGE>

          (c) to provide for uncertificated Notes in addition to certificated
     Notes;

          (d) to make any change that does not adversely affect the legal rights
     hereunder of any Noteholder;

          (e) to comply with the requirements of the SEC in order to maintain
     the qualification of the Indenture under the TIA; or

          (f) to make any change that provides any additional rights or benefits
     to the holders of Notes.

          An amendment under this Section may not make any change that adversely
affects the rights under Article VI of any holder of Senior Debt then
outstanding unless the holders of such Senior Debt (or any group or
representative thereof authorized to give a consent) consent to such change.

          SECTION 11.02. With Consent of Noteholders. Subject to Section 8.07
                         ---------------------------
hereof, the Company and the Trustee may amend or supplement this Indenture or
the Notes with the written consent (including consents obtained in connection
with any tender offer or exchange offer for Notes) of the Noteholders of at
least a majority in principal amount of the then outstanding Notes. Subject to
Sections 8.04 and 8.07 hereof, the Noteholders of a majority in principal amount
of the Notes then outstanding may also by their written consent (including
consents obtained in connection with any tender offer or exchange offer for
Notes) waive any existing Default or Event of Default as provided in Section
8.04 or waive compliance in a particular instance by the Company with any
provision of this Indenture or the Notes. However, without the consent of each
Noteholder affected, an amendment, supplement or waiver under this Section may
not (with respect to any Notes held by a nonconsenting Noteholder):

          (a) reduce the amount of Notes whose Noteholders must consent to an
     amendment, supplement or waiver;

          (b) reduce the rate of or change the time for payment of interest on
     any Note;

          (c) reduce the principal of or change the fixed maturity of any Note
     or alter the redemption provisions with respect thereto;

          (d) make any Note payable in money other than that stated in the Note;

          (f) waive a default in the payment of the principal of, or interest
     on, any Note (except a rescission of acceleration of the Notes by the
     Noteholders of at least a majority in aggregate principal amount of the
     then outstanding Notes and the waiver of the payment default that resulted
     from such acceleration);

          (g) waive a redemption payment payable on any Note;

                                      -41-

<PAGE>

          (h) impair the right of Noteholders to convert Notes into Common Stock
     of the Company or waive or otherwise adversely affect the rights of any
     Noteholders under Section 4.06; or

          (i) modify Articles V or VI hereof in a manner adverse to the
     Noteholders.

          To secure a consent of the Noteholders under this Section 11.02, it
shall not be necessary for the Noteholders to approve the particular form of any
proposed amendment, supplement or waiver, but it shall be sufficient if such
consent approves the substance thereof.

          An amendment under this Section may not make any change that adversely
affects the rights under Article VI of any holder of Senior Debt then
outstanding unless the holders of such Senior Debt (or any group or
representative thereof authorized to give a consent) consent to such change.

          After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to Noteholders a notice briefly describing the
amendment or waiver.

          SECTION 11.03. Compliance with Trust Indenture Act. Every amendment to
                         -----------------------------------
this Indenture or the Notes shall be set forth in a supplemental indenture that
complies with the TIA as then in effect.

          SECTION 11.04. Revocation and Effect of Consents. Until an amendment,
                         ---------------------------------
supplement or waiver becomes effective, a consent to it by a Noteholder of a
Note is a continuing consent by the Noteholder and every subsequent Noteholder
of a Note or portion of a Note that evidences the same debt as the consenting
Noteholder's Note, even if notation of the consent is not made on any Note.
However, any such Noteholder or subsequent Noteholder may revoke the consent as
to such Noteholder's Note or portion of a Note if the Trustee receives the
written notice of revocation at least one business day before the date on which
the Trustee receives an Officers' Certificate certifying that the Noteholders of
the requisite principal amount of Notes have consented to the amendment,
supplement or waiver.

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Noteholders entitled to consent to any amendment,
supplement or waiver. If a record date is fixed, then notwithstanding the
provisions of the immediately preceding paragraph, those Persons who were
Noteholders at such record date (or their duly designated proxies), and only
those Persons, shall be entitled to consent to such amendment, supplement or
waiver or to revoke any consent previously given, whether or not such Persons
continue to be Noteholders after such record date. No consent shall be valid or
effective for more than 90 days after such record date unless consents from
Noteholders of the principal amount of Notes required hereunder for such
amendment or waiver to be effective shall have also been given and not revoked
within such 90-day period.

          After an amendment, supplement or waiver becomes effective it shall
bind every Noteholder, unless it is of the type described in any of clauses (a)
through (i) of Section 11.02 hereof. In such case, the amendment or waiver shall
bind each Noteholder who has consented to

                                      -42-

<PAGE>

it and every subsequent Noteholder that evidences the same debt as the
consenting Noteholder's Note.

          SECTION 11.05. Notation on or Exchange of Notes. The Trustee shall,
                         --------------------------------
upon the written request and expense of the Company, place an appropriate
notation about an amendment or waiver on any Note thereafter authenticated. The
Company in exchange for all Notes may issue and the Trustee shall authenticate
new Notes that reflect the amendment or waiver.

          SECTION 11.06. Trustee Protected. The Trustee shall sign all
                         -----------------
supplemental indentures, except that the Trustee may, but need not, sign any
supplemental indenture that adversely affects its rights. In executing, or
accepting the additional trusts created by, any supplemental indenture permitted
by this Article or the modification thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this indenture.

                                  Miscellaneous
                                  -------------

          SECTION 12.01. Trust Indenture Act Controls. If any provision of this
                         ----------------------------
Indenture limits, qualifies, or conflicts with another provision which is
automatically deemed to be incorporated in this Indenture by the TIA, the
incorporated provision shall control.

          SECTION 12.02. Notices. Any notice or communication by the Company or
                         -------
the Trustee to the other is duly given if in writing and delivered in person or
mailed by first-class mail to the other's address stated in Section 12.09
hereof. The Company or the Trustee by notice to the other may designate
additional or different addresses for subsequent notices or communications.

          Any notice or communication to a Noteholder shall be mailed by
first-class mail to his address shown on the register kept by the Registrar.
Failure to mail a notice or communication to a Noteholder or any defect in it
shall not affect its sufficiency with respect to other Noteholders.

          If a notice or communication is mailed in the manner provided above
within the time prescribed, it is duly given, whether or not the addressee
receives it.

          If the Company mails a notice or communication to Noteholders, it
shall mail a copy to the Trustee and each Agent at the same time.

          All other notices or communications shall also be in writing.

          In case by reason of the suspension of regular mail service, or by
reason of any other cause, it shall be impossible to mail any notice as required
by the Indenture, then such method of notification as shall be made with the
approval of the Trustee shall constitute a sufficient mailing of such notice.

TRUSTEE'S CERTIFICATE OF
AUTHENTICATION

This is one of the 7 1/2%
Convertible Subordinated Notes
Due 2006 described in the
within-mentioned Indenture.

FIRST UNION NATIONAL BANK,
as Trustee,


By:
   -----------------------------
       Authorized Signatory

                                      -3-

                             CHARMING SHOPPES, INC.

                  7 1/2% Convertible Subordinated Note Due 2006

     1. Interest. CHARMING SHOPPES, INC., a Pennsylvania corporation (the
        --------
"Company"), is the issuer of this 7 1/2% Convertible Subordinated Note Due 2006
(the "Convertible Note"). The Company promises to pay interest on the
Convertible Notes at the rate per annum shown above, in cash semiannually on
each January 15 and July 15, commencing on January 15, 1997, to holders of
record on the immediately preceding January 1 or July 1, as the case may be.

     Interest on the Convertible Notes will accrue from the most recent date to
which interest has been paid, or if no interest has been paid, from July 22,
1996. Interest will be computed on the basis of a 360-day year of 12 30-day
months. To the extent lawful, the Company shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest (without regard to any applicable grace period) at the
rate borne by the Convertible Notes, compounded semi-annually.

     2. Method of Payment. The Company will pay interest on the Convertible
        -----------------
Notes (except defaulted interest) to the persons who are registered holders of
the Convertible Notes at the close of business on the record date for the next
interest payment date even though Convertible Notes are cancelled after the
record date and on or before the interest payment date. To collect principal
payments, the Noteholder hereof must surrender this Convertible Notes to the
office or agency of the Company maintained for that purpose. The Company will
pay principal and interest in money of the United States that at the time of
payment is legal tender for payment of public and private debts. The Company may
pay principal by check payable in such money or by wire transfer to a dollar
account maintained by the holder (if the holder of the Convertible Notes holds
an aggregate principal amount of Convertible Notes in excess of $5,000,000). The
Company may pay interest by mailing a dollar check to a holder's registered
address or, upon application by the holder hereof to the Registrar, not later
than the applicable record date, by wire transfer to a dollar account maintained
by the holder (if the holder of the Convertible Notes holds an aggregate
principal amount of Convertible Notes in excess of $5,000,000).

     3. Paying Agent, Registrar and Conversion Agent. The Trustee will initially
        --------------------------------------------
act as Paying Agent, Registrar and Conversion Agent. The Company may change any
Paying Agent, Registrar, co-registrar or Conversion Agent without prior notice.
The Company or any of its Affiliates may act in any such capacity.

     4. Indenture. The Company issued the Convertible Notes under an indenture,
        ---------
dated as of July 22, 1996 (the "Indenture"), between the Company and First Union
National Bank, as Trustee. The terms of the Convertible Notes include those
stated in the Indenture and those made part of the Indenture by the Trust
Indenture Act of 1939 (15 U.S. Code Sections 77aaa-77bbbb) as in effect on the
date of the Indenture. The Convertible Notes are subject to, and qualified by,
all such terms, certain of which are summarized hereon, and Noteholders are
referred to the Indenture and such Act for a statement of such terms. The
Convertible Notes are unsecured

                                      -4-

<PAGE>

obligations of the Company limited to (except as otherwise provided in the
Indenture) an aggregate principal amount of $120,000,000 (plus up to $18,000,000
aggregate principal amount of Convertible Notes that may be sold by the Company
pursuant to the over-allotment option granted pursuant to the Underwriting
Agreement dated July 16, 1996 between the Company and the Underwriters), and are
subordinated in right of payment to all existing and future Senior Debt of the
Company as provided in the Indenture. Any holder of this Convertible Note shall
be deemed to have agreed to and be bound by all the terms and conditions
contained in the Indenture applicable to a holder of a Convertible Note.

     5. Optional Redemption. The Convertible Notes are not subject to redemption
        -------------------
at the Company's option prior to July 15, 1999. On such date and thereafter, the
Convertible Notes will be subject to redemption at the option of the Company, in
whole or in part (in any integral multiple of $1,000), upon not less than 30 nor
more than 60 days prior notice by mail at the following redemption prices
(expressed as percentages of the principal amount), if redeemed during the
12-month period beginning July 15 of the years indicated:

                             Redemption
Year                            Price
----                         ----------
1999......................    103.750%
2000......................    103.125
2001......................    102.500
2002......................    101.875
2003......................    101.250
2004......................    100.625

and, at July 15, 2005 and thereafter, 100%, in each case together with accrued
interest up to but not including the redemption date (subject to the right of
holders of record on the relevant record date to receive interest due on an
interest payment date). If less than all Convertible Notes are to be redeemed,
the Trustee will select the Convertible Notes to be redeemed by lot. On or after
the redemption date, interest will cease to accrue on the Convertible Notes, or
portion thereof, called for redemption unless the Company defaults in making
such redemption.

     6. Notice of Redemption. Notice of intention to redeem Convertible Notes
        --------------------
will be mailed at least 30 days but not more than 60 days prior to the
redemption date to each holder of the Convertible Notes to be redeemed at his
address of record. The Convertible Notes in denominations larger than $1,000 may
be redeemed in part but only in integral multiples of $1,000. In the event of a
redemption of less than all of the Convertible Notes, the Convertible Notes will
be chosen for redemption by the Trustee in accordance with the Indenture. Unless
the Company defaults in making such redemption payment, or the Paying Agent is
prohibited from making such payment pursuant to the Indenture, interest ceases
to accrue on the Convertible Notes or portions of them called for redemption on
and after the redemption date.

     If this Convertible Note is redeemed subsequent to a record date with
respect to any interest payment date specified above and on or prior to such
interest payment date, then any

                                      -5-

<PAGE>

accrued interest will be paid to the person in whose name this Convertible Note
is registered at the close of business on such record date.

     7. Mandatory Redemption. The Company will not be required to make mandatory
        --------------------
redemption payments with respect to the Convertible Notes. There are no sinking
fund payments with respect to the Convertible Notes.

     8. Repurchase at Option of Holder. If there is a Change of Control, the
        ------------------------------
Company shall be required to offer to purchase on the Change of Control Payment
Date all outstanding Convertible Notes at a purchase price equal to 100% of the
principal amount thereof on the date of purchase, plus accrued and unpaid
interest to the Change of Control Payment Date; provided, however, that if a
                                                --------  -------
Change of Control Payment Date is on or after a record date and on or before the
related interest payment date, any accrued interest shall be payable to the
registered holder hereof at the close of business on the relevant record date.
Holders of Convertible Notes that are subject to an offer to purchase will
receive a Change of Control Offer from the Company prior to any related Change
of Control Payment Date and may elect, pursuant to the terms of the Indenture,
to have such Convertible Notes or portions thereof in authorized denominations
purchased by completing the form entitled "Option of Noteholder To Elect
Purchase" appearing below.

     9. Subordination. The payment of the principal of, interest on or any other
        -------------
amounts due on the Convertible Notes is subordinated in right of payment to the
prior payment in full of all existing and future Senior Debt of the Company, as
described in the Indenture. Each Noteholder, by accepting a Convertible Note,
agrees to such subordination and authorizes and directs the Trustee on its
behalf to take such action as may be necessary or appropriate to effectuate the
subordination so provided and appoints the Trustee as its attorney-in-fact for
such purpose.

     10. Conversion. The holder of any Convertible Note has the right,
         ----------
exercisable at any time prior to the close of business (New York time) on the
date of the Convertible Note's maturity, to convert the principal amount thereof
(or any portion thereof that is an integral multiple of $1,000) into shares of
Common Stock at the initial Conversion Price of $7.46 per share, subject to
adjustment under certain circumstances, except (i) that if a Convertible Note is
called for redemption, the conversion right will terminate at the close of
business on the Business Day immediately preceding the date fixed for redemption
and (ii) if a Convertible Note is submitted for repurchase in connection with a
Change of Control, the conversion right will terminate with respect to the
portion submitted for repurchase upon such submission.

          To convert a Convertible Note, a holder must (1) complete and sign a
notice of election to convert substantially in the form set forth below (unless
the holder is The Depository Trust Company ("DTC") or its nominee, in which case
DTC's customary operational arrangements will apply), (2) surrender the
Convertible Note to a Conversion Agent, (3) furnish appropriate endorsements or
transfer documents if required by the Registrar or Conversion Agent and (4) pay
any transfer or similar tax, if required. Upon conversion, no adjustment or
payment will be made for interest or dividends, but if any Noteholder surrenders
a Convertible Note for conversion after the close of business on the record date
for the payment of an installment of

                                      -6-

<PAGE>

interest and prior to the opening of business on the next interest payment date,
then, notwithstanding such conversion, the interest payable on such interest
payment date will be paid to the registered holder of such Convertible Note on
such record date. In such event, such Convertible Note, when surrendered for
conversion, must be accompanied by payment in funds acceptable to the Company of
an amount equal to the interest payable on such interest payment date on the
principal amount so converted. The interest payment with respect to a
Convertible Note called for redemption on a date during the period from the
close of business on or after any record date to the opening of business on the
business day following the corresponding interest payment date will be payable
on the corresponding interest payment date to the holder of such Convertible
Note on such record date (notwithstanding the conversion of such Convertible
Note before the corresponding interest payment date) and a holder who elects to
convert need not include funds equal to the interest payment. The number of
shares of Common Stock issuable upon conversion of a Convertible Note is
determined by dividing the principal amount of the Convertible Note converted by
the Conversion Price in effect on the Conversion Date. No fractional shares will
be issued upon conversion but a cash adjustment will be made for any fractional
interest.

     11. Denominations, Transfer, Exchange. The Convertible Notes are in
         ---------------------------------
registered form, without coupons, in denominations of $1,000 and integral
multiples of $1,000. The transfer of Convertible Notes may be registered, and
Convertible Notes may be exchanged, as provided in the Indenture. The Registrar
may require a Noteholder, among other things, to furnish appropriate
endorsements and transfer documents and to pay any taxes and fees required by
law or permitted by the Indenture. The Registrar need not exchange or register
the transfer of any Convertible Note or portion of a Convertible Note selected
for redemption (except the unredeemed portion of any Convertible Note being
redeemed in part). Also, it need not exchange or register the transfer of any
Convertible Note for a period of 15 days before a selection of Convertible Notes
to be redeemed.

     12. Persons Deemed Owners. Except as provided in paragraph 2 of this
         ---------------------
Convertible Note, the registered Noteholder of a Convertible Note may be treated
as its owner for all purposes.

     13. Unclaimed Money. If money for the payment of principal or interest
         ---------------
remains unclaimed for two years, the Trustee and the Paying Agent shall pay the
money back to the Company at its written request. After that, Noteholders of
Convertible Notes entitled to the money must look only to the Company for
payment unless an abandoned property law designates another person and all
liability of the Trustee and such Paying Agent with respect to such money shall
cease.

     14. Defaults and Remedies. The Convertible Notes shall have the Events of
         ---------------------
Default as set forth in Section 8.01 of the Indenture. Subject to certain
limitations in the Indenture, if an Event of Default occurs and is continuing,
the Trustee by notice to the Company or the Noteholders of at least 25% in
aggregate principal amount of the then outstanding Convertible Notes by notice
to the Company and the Trustee may declare all the Convertible Notes to be due
and payable immediately, except that in the case of an Event of Default arising
from certain events of bankruptcy or insolvency with respect to the Company or
any Material Subsidiary, all

                                      -7-

<PAGE>

unpaid principal and interest accrued on the Convertible Notes shall become due
and payable immediately without further action or notice. Upon acceleration as
described in either of the preceding sentences, the subordination provisions of
the Indenture preclude any payment being made to Noteholders for at least 5 days
except as otherwise provided in the Indenture.

          The Noteholders of a majority in aggregate principal amount of the
Convertible Notes then outstanding by written notice to the Trustee may rescind
and annul an acceleration and its consequences if the rescission would not
conflict with any judgment or decree and if all Events of Default have been
cured or waived except nonpayment of principal or interest that has become due
solely because of the acceleration. Noteholders may not enforce the Indenture or
the Convertible Notes except as provided in the Indenture. Subject to certain
limitations, Noteholders of a majority in principal amount of the then
outstanding Convertible Notes issued under the Indenture may direct the Trustee
in its exercise of any trust or power. The Company must furnish compliance
certificates to the Trustee annually. The above description of Events of Default
and remedies is qualified by reference to, and subject in its entirety by, the
