Officer shall attest to, the Debenture for the Company by manual or facsimile
signature. The Company's seal shall be impressed, affixed, imprinted or

authenticated pursuant to the terms of this Indenture.

                  The Trustee shall authenticate the Debentures for original
issue in the aggregate principal amount of up to $80,500,00 upon a written order
of the Company in the form of an Officers' Certificate. The Officers'

date on which the Debentures are to be authenticated. The aggregate principal
amount of Debentures outstanding at any time may not exceed $80,500,000 except

aggregate principal amount shall not be issued on the Issue Date other than
pursuant to the over-allotment option granted by the Company to the underwriters
thereof, but may be issued subsequent to the initial issuance of Debentures, and
the Trustee shall not authenticate in excess of $70,000,000 aggregate principal
amount of Debentures on the Issue Date unless the written order of the Company
in respect of such issuance certifies that such additional aggregate principal
amount of Debentures are being issued pursuant to such over-allotment option.
Upon the written order of the Company in the form of an Officers' Certificate,
the Trustee shall authenticate Debentures in substitution of Debentures
originally issued to reflect any name change of the Company.

                  The Trustee may appoint an authenticating agent acceptable to
the Company to authenticate Debentures. Unless otherwise provided in the
appointment, an authenticating agent may authenticate Debentures 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, any Affiliate of the Company,
or any of their respective Subsidiaries.

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

                                       12

                  SECTION 2.3.  REGISTRAR AND PAYING AGENT.

                  The Company shall maintain an office or agency in the Borough
of Manhattan, The City of New York, where Debentures may be presented for
registration of transfer or for exchange ("Registrar") and an office or agency
where Debentures may be presented for payment ("Paying Agent") and where notices
and demands to or upon the Company in respect of the Debentures may be served.
The Company may act as Registrar or Paying Agent, except that, for the purposes
of Articles III, VIII and XI and as otherwise specified in the Indenture,
neither the Company nor any Affiliate of the Company shall act as Paying Agent.
The Registrar shall keep a register of the Debentures and of their transfer and
exchange. The Company may have one or more co-Registrars and one or more
additional Paying Agents. The term "Paying Agent" includes any additional Paying
Agent. The Company hereby initially appoints the Trustee as Registrar and Paying
Agent, and the Trustee hereby initially agrees so to act.

                  The Company shall enter into an appropriate written agency
agreement with any Agent not a party to this Indenture, which agreement shall
implement the provisions of this Indenture that relate to such Agent. The
Company shall promptly notify the Trustee in writing of the name and address of
any such Agent. If the Company fails to maintain a Registrar or Paying Agent,
the Trustee shall act as such.

                  SECTION 2.4.  PAYING AGENT TO HOLD ASSETS IN
TRUST.

                  The Company shall require each Paying Agent other than the
Trustee to agree in writing that each Paying Agent shall hold in trust for the
benefit of Holders or the Trustee all assets held by the Paying Agent for the
payment of principal of, premium, if any, or interest on, the Debentures
(whether such assets have been distributed to it by the Company or any other
obligor on the Debentures), and shall notify the Trustee in writing of any
Default in making any such payment. If either of the Company or a Subsidiary of
the Company acts as Paying Agent, it shall segregate such assets and hold them
as a separate trust fund for the benefit of the Holders or the Trustee. The
Company at any time may require a Paying Agent to distribute all assets held by
it to the Trustee and account for any assets disbursed and the Trustee may at
any time during the continuance of any Default or Event of Default, upon written
request to a

                                       13

Paying Agent, require such Paying Agent to distribute all assets held by it to
the Trustee and to account for any assets distributed. Upon distribution to the
Trustee of all assets that shall have been delivered by the Company to the
Paying Agent, the Paying Agent (if other than the Company or an Affiliate of the
Company) shall have no further liability for such assets.

                  SECTION 2.5.  SECURITYHOLDER LIST.

                  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 Holders and shall otherwise comply with TIA ss. 312(a). If the
Trustee is not the Registrar, the Company shall furnish to the Trustee on or
before the fifth Business Day preceding 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 reasonably may require of the names and addresses of
Holders.

                  SECTION 2.6.  TRANSFER AND EXCHANGE.

                  When Debentures are presented to the Registrar or a
co-Registrar with a request to register the transfer of such Debentures or to
exchange such Debentures for an equal principal amount of Debentures of other
authorized denominations, the Registrar or co-Registrar shall register the
transfer or make the exchange as requested if its reasonable requirements for
such transaction are met; PROVIDED, HOWEVER, that the Debentures surrendered for
registration of transfer or exchange shall be duly endorsed or accompanied by a
written instrument of transfer in form reasonably satisfactory to the Registrar
or co-Registrar, duly executed by the Holder thereof or his attorney duly
authorized in writing.

                  To permit registrations of transfers and exchanges, the
Company shall execute and the Trustee shall authenticate Debentures at the
Registrar's or co-Registrar's request. No service charge shall be made for any
registration of transfer or exchange, but the Company may require payment of a
sum sufficient to cover any transfer tax, assessments, or similar governmental
charge payable in connection therewith. The Registrar or co-Registrar shall not
be required to register the transfer of or exchange (a) any Debenture selected
for redemption in whole or in part pursuant to Article III, except the
unredeemed portion of any Debenture

                                       14

being redeemed in part, or (b) any Debenture for a period beginning 15 Business
Days before the mailing of a notice of an offer to repurchase pursuant to
Article XI or of redemption of Debentures pursuant to Article III hereof and
ending at the close of business on the day of such mailing.

                  SECTION 2.7.  REPLACEMENT DEBENTURES.

                  If a mutilated Debenture is surrendered to the Trustee or if
the Holder of a Debenture claims and submits an affidavit or other evidence,
satisfactory to the Trustee, to the Trustee to the effect that the Debenture has
been lost, destroyed or wrongfully taken, the Company shall issue and the
Trustee shall authenticate a replacement Debenture if the Trustee's requirements
are met. If required by the Trustee or the Company, such Holder must provide an
indemnity bond or other indemnity, sufficient in the judgment of both the
Company and the Trustee, to protect the Company, the Trustee or any Agent from
any loss which any of them may suffer if a Debenture is replaced. The Company
may charge such Holder for its reasonable, out-of-pocket expenses in replacing a
Debenture.

                  Every replacement Debenture is an additional obligation of the
Company.

                  SECTION 2.8.  OUTSTANDING DEBENTURES.

                  Debentures outstanding at any time are all the Debentures that
have been authenticated by the Trustee except those canceled by it, those
delivered to it for cancellation and those described in this Section 2.8 as not
outstanding. A Debenture does not cease to be outstanding because the Company or
an Affiliate of the Company holds the Debenture, except as provided in Section
2.9.

                  If a Debenture is replaced pursuant to Section 2.7 (other than
a mutilated Debenture surrendered for replacement), it ceases to be outstanding
unless the Trustee and the Company receives proof satisfactory to it that the
replaced Debenture is held by a BONA FIDE purchaser. A mutilated Debenture
ceases to be outstanding upon surrender of such Debenture and replacement
thereof pursuant to Section 2.7.

                                       15

                  SECTION 2.9.  TREASURY DEBENTURES.

                  In determining whether the Holders of the required principal
amount of Debentures have concurred in any direction, amendment, supplement,
waiver or consent, Debentures owned by the Company or an Affiliate of the
Company shall be disregarded, except that, for the purposes of determining
whether the Trustee shall be protected in relying on any such direction,
amendment, supplement, waiver or consent, only Debentures that a Trust Officer
of the Trustee knows are so owned shall be disregarded.

                  SECTION 2.10.  TEMPORARY DEBENTURES.

                  Until definitive Debentures are ready for delivery, the
Company may prepare and the Trustee shall authenticate temporary Debentures.
Temporary Debentures shall be substantially in the form of definitive Debentures
but may have variations that the Company reasonably and in good faith considers
appropriate for temporary Debentures. Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate definitive Debentures in
exchange for temporary Debentures. Until so exchanged, the temporary Debentures
shall in all respects be entitled to the same benefits under this Indenture as
permanent Debentures authenticated and delivered hereunder.

                  SECTION 2.11.  CANCELLATION.

                  The Company at any time may deliver Debentures to the Trustee
for cancellation. The Registrar and the Paying Agent shall forward to the
Trustee any Debentures surrendered to them for registration of transfer,
exchange or payment. The Trustee, or at the written direction of the Trustee,
the Registrar or the Paying Agent (other than the Company or an Affiliate of the
Company), and no one else, shall cancel and, at the written direction of the
Company, shall dispose of all Debentures surrendered for registration of
transfer, exchange, payment or cancellation. Subject to Section 2.7, the Company
may not issue new Debentures to replace Debentures that have been paid or
delivered to the Trustee for cancellation. No Debentures shall be authenticated
in lieu of or in exchange for any Debentures canceled as provided in this
Section 2.11, except as expressly permitted in the form of Debentures and as
permitted by this Indenture.

                                       16

                  SECTION 2.12.  DEFAULTED INTEREST.

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

                  Any interest on any Debenture which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date plus, to the
extent lawful, any interest payable on the defaulted interest (hereinafter
called "Defaulted Interest") shall forthwith cease to be payable to the
registered holder on the relevant Record Date, and such Defaulted Interest may
be paid by the Company, at its election in each case, as provided in clause (1)
or (2) below:

                     (1) The Company may elect to make pay-
         ment of any Defaulted Interest to the persons in whose names the
         Debentures (or their respective predecessor Debentures) are registered
         at the close of business on a Special Record Date for the payment of
         such Defaulted Interest, which shall be fixed in the following manner.
         The Company shall notify the Trustee in writing of the amount of
         Defaulted Interest proposed to be paid on each Debenture and the date
         of the proposed payment, and at the same time the Company shall deposit
         with the Trustee an amount of Cash equal to the aggregate amount
         proposed to be paid in respect of such Defaulted Interest or shall make
         arrangements satisfactory to the Trustee for such deposit prior to the
         date of the proposed payment, such Cash when deposited to be held in
         trust for the benefit of the persons entitled to such Defaulted
         Interest as provided in this clause (1). Thereupon the Trustee shall
         fix a Special Record Date for the payment of such Defaulted Interest
         which shall be not more than 15 days and not less than 10 days prior to
         the date of the proposed payment and not less than 10 days after the
         receipt by the Trustee of the notice of the proposed payment. The
         Trustee shall promptly notify the Company of such Special Record Date
         and, in the name and at the expense of the Company, shall cause notice
         of the proposed payment of such Defaulted Interest and the Special
         Record Date therefor to be mailed, first-class postage prepaid, to each
         Holder at his address as it appears in the Debenture

                                       17

         register not less than 10 days prior to such Special Record Date.
         Notice of the proposed payment of such Defaulted Interest and the
         Special Record Date therefor having been mailed as aforesaid, such
         Defaulted Interest shall be paid to the persons in whose names the
         Debentures (or their respective predecessor Debentures) are registered
         on such Special Record Date and shall no longer be payable pursuant to
         the following clause (2).

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

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

                  SECTION 2.13.  PERSONS DEEMED OWNERS.

                  The Company, the Trustee, any Agent and any authenticating
agent may treat the person in whose name any Debenture is registered as the
owner of such Debenture for the purpose of receiving payments of principal of or
interest on such Debenture and for all other purposes. None of the Company, the
Trustee, any Agent or any authenticating agent shall be affected by any notice
to the contrary.


                                   ARTICLE III

                                   REDEMPTION

                  SECTION 3.1.  RIGHT OF REDEMPTION.

                  Redemption of Debentures, as permitted by any provision of
this Indenture, shall be made in accordance with Paragraph 5 of the Debentures
and this Article III. The Company will not have the right to redeem any
Debentures prior to February 15, 1999. On or after February 15, 1999, the
Company will have the right to redeem all or any part of

                                       18

the Debentures at the Redemption Prices specified in Paragraph 5 therein under
the caption "Redemption," in each case including accrued and unpaid interest to
the Redemption Date.

                  SECTION 3.2.  NOTICES TO TRUSTEE.

                  If the Company elects to redeem Debentures pursuant to
Paragraph 5 of the Debentures, it shall notify the Trustee in writing of the
Redemption Date and the principal amount of Debentures to be redeemed and
whether it wants the Trustee to give notice of redemption to the Holders.

                  The Company shall give each notice to the Trustee provided for
in this Section 3.2 at least 45 days before the Redemption Date (unless a
shorter notice shall be satisfactory to the Trustee). Any such notice may be
canceled at any time prior to notice of such redemption being mailed to any
Holder and shall thereby be void and of no effect.

                  SECTION 3.3.  SELECTION OF DEBENTURES TO BE RE-
DEEMED.

                  If less than all of the Debentures are to be redeemed pursuant
to Paragraph 5 thereof, the Trustee shall select the Debentures to be redeemed
on a pro rata basis, by lot or by such other method as the Trustee shall
determine to be fair and appropriate and in such manner as complies with any
applicable depositary, legal and stock exchange requirements.

                  The Trustee shall make the selection from the Debentures
outstanding and not previously called for redemption and shall promptly notify
the Company in writing of the Debentures selected for redemption and, in the
case of any Debenture selected for partial redemption, the principal amount
thereof to be redeemed. Debentures in denominations of $1,000 may be redeemed
only in whole. The Trustee may select for redemption portions (equal to $1,000
or any integral multiple thereof) of the principal of Debentures that have
denominations larger than $1,000. Provisions of this Indenture that apply to
Debentures called for redemption also apply to portions of Debentures called for
redemption.

                                       19

                  SECTION 3.4.  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 by first class mail, postage
prepaid, to the Trustee and each Holder whose Debentures are to be redeemed. At
the Company's request, the Trustee shall give the notice of redemption in the
Company's name and at the Company's expense. Each notice for redemption shall
identify the Debentures to be redeemed and shall state:

                      (1) the Redemption Date, and that the
         Debentures called for redemption may not be converted
         after the fifth Business Day prior to the Redemption
         Date;

                     (2) the Redemption Price, including the
         amount of accrued and unpaid interest to be paid upon
         such redemption;

                       (3) the name, address and telephone
         number of the Paying Agent;

                     (4) that Debentures called for redemp-
         tion must be surrendered to the Paying Agent at the
         address specified in such notice to collect the Redemp-
         tion Price;

                      (5) that, unless (a) the Company de-
         faults in its obligation to deposit Cash with the Paying Agent in
         accordance with Section 3.6 hereof or (b) such redemption payment is
         prohibited pursuant to Article XII hereof or otherwise, interest on
         Debentures called for redemption ceases to accrue on and after the
         Redemption Date and the only remaining right of the Holders of such
         Debentures is to receive payment of the Redemption Price, including
         accrued and unpaid interest to the Redemption Date, upon surrender to
         the Paying Agent of the Debentures called for redemption and to be
         redeemed;

                     (6) if any Debenture is being redeemed
         in part, the portion of the principal amount, equal to $1,000 or any
         integral multiple thereof, of such Debenture to be redeemed and that,
         after the Redemption Date, and upon surrender of such Debenture, a new
         Debenture or Debentures in aggregate principal amount equal to the
         unredeemed portion thereof will be issued;

                                       20

                     (7) if less than all the Debentures are
         to be redeemed, the identification of the particular Debentures (or
         portion thereof) to be redeemed, as well as the aggregate principal
         amount of such Debentures to be redeemed and the aggregate principal
         amount of Debentures to be outstanding after such partial redemption;

                     (8) the CUSIP number of the Debentures
         to be redeemed; and

                     (9) that the notice is being sent pur-
         suant to this Section 3.4 and pursuant to the redemption provisions of
         Paragraph 5 of the Debentures.

                  SECTION 3.5.  EFFECT OF NOTICE OF REDEMPTION.

                  Once notice of redemption is mailed in accordance with Section
3.4, Debentures called for redemption become due and payable on the Redemption
Date and at the Redemption Price, including accrued and unpaid interest to the
Redemption Date. Upon surrender to the Trustee or Paying Agent, such Debentures
called for redemption shall be paid at the Redemption Price, including interest,
if any, accrued and unpaid to the Redemption Date; PROVIDED that if the
Redemption Date is after a regular Record Date and on or prior to the
corresponding Interest Payment Date, the accrued interest shall be payable to
the Holder of the redeemed Debentures registered on the relevant Record Date;
and PROVIDED, FURTHER, that if a Redemption Date is a Legal Holiday, payment
shall be made on the next succeeding Business Day and no interest shall accrue
for the period from such Redemption Date to such succeeding Business Day.

                  SECTION 3.6.  DEPOSIT OF REDEMPTION PRICE.

                  On or prior to the Redemption Date, the Company shall deposit
with the Paying Agent (other than the Company or an Affiliate of the Company)
Cash sufficient to pay the Redemption Price of, including accrued and unpaid
interest on, all Debentures to be redeemed on such Redemption Date (other than
Debentures or portions thereof called for redemption on that date that have been
delivered by the Company to the Trustee for cancellation). The Paying Agent
shall promptly return to the Company any Cash so deposited which is not required
for that purpose upon the written request of the Company.

                                       21

                  If the Company complies with the preceding paragraph and the
other provisions of this Article III and payment of the Debentures called for
redemption is not prohibited under Article XII or otherwise, interest on the
Debentures to be redeemed will cease to accrue on the applicable Redemption
Date, whether or not such Debentures are presented for payment. Notwithstanding
anything herein to the contrary, if any Debenture surrendered for redemption in
the manner provided in the Debentures shall not be so paid upon surrender for
redemption because of the failure of the Company to comply with the preceding
paragraph, interest shall continue to accrue and be paid from the Redemption
Date until such payment is made on the unpaid principal, and, to the extent
lawful, on any interest not paid on such unpaid principal, in each case at the
rate and in the manner provided in Section 4.1 hereof and the Debenture.

                  SECTION 3.7.  DEBENTURES REDEEMED IN PART.

                  Upon surrender of a Debenture that is to be redeemed in part,
the Company shall execute and the Trustee shall authenticate and deliver to the
Holder, without service charge to the Holder, a new Debenture or Debentures
equal in principal amount to the unredeemed portion of the Debenture
surrendered.

                                   ARTICLE IV

                                    COVENANTS

                  SECTION 4.1.  PAYMENT OF DEBENTURES.

                  The Company shall pay the principal of and interest on the
Debentures on the dates and in the manner provided in the Debentures. An
installment of principal of or interest on the Debentures shall be considered
paid on the date it is due if the Trustee or Paying Agent (other than the
Company or an Affiliate of the Company) holds for the benefit of the Holders, on
or before 10:00 a.m. New York City time on that date, Cash deposited and
designated for and sufficient to pay the installment.

                  The Company shall pay interest on overdue principal and on
overdue installments of interest at the rate specified in the Debentures
compounded semi-annually, to the extent lawful.

                                       22

                  SECTION 4.2.  MAINTENANCE OF OFFICE OR AGENCY.

                  The Company shall maintain in the Borough of Manhattan, The
City of New York, an office or agency where Debentures may be presented or
surrendered for payment, where Debentures may be surrendered for registration of
transfer or exchange and for conversion and where notices and demands to or upon
the Company in respect of the Debentures and this Indenture may be served. The
Company shall give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the address of the Trustee set
forth in Section 14.2.

                  The Company may also from time to time designate one or more
other offices or agencies where the Debentures may be presented or surrendered
for any or all such purposes and may from time to time rescind such
designations; PROVIDED, HOWEVER, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in the Borough of Manhattan, The City of New York, for such purposes. The
Company shall give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency. The Company hereby initially designates the Corporate Trust Office of
the Trustee as such office.

                  SECTION 4.3.  CORPORATE EXISTENCE.

                  Subject to Article V, the Company shall do or cause to be done
all things necessary to preserve and keep in full force and effect its corporate
existence and the corporate or other existence of each of its Subsidiaries in
accordance with the respective organizational documents of each of them and the
rights (charter and statutory) and corporate franchises of the Company and each
of its Subsidiaries; PROVIDED, HOWEVER, that the Company shall not be required
to preserve, with respect to itself, any right or franchise, and with respect to
any of its Subsidiaries, any such existence, right or franchise, if (a) the
Company shall determine that the preservation thereof is no longer desirable in
the conduct of the business of such entity and (b) the loss thereof is not
disadvantageous in any material respect to the Holders.

                                       23

                  SECTION 4.4.  PAYMENT OF TAXES AND OTHER CLAIMS.

                  Except with respect to immaterial items, the Company shall,
and shall cause each of its Subsidiaries to, pay or discharge or cause to be
paid or discharged, before the same shall become delinquent, (i) all taxes,
assessments and governmental charges (including withholding taxes and any
penalties, interest and additions to taxes) levied or imposed upon the Company
or any of its Subsidiaries or any of their respective properties and assets and
(ii) all lawful claims, whether for labor, materials, supplies, services or
anything else, which have become due and payable and which by law have or may
become a Lien upon the property and assets of the Company or any of its
Subsidiaries; PROVIDED, HOWEVER, that neither the Company nor any Subsidiary
shall be required to pay or discharge or cause to be paid or discharged any such
tax, assessment, charge or claim whose amount, applicability or validity is
being contested in good faith by appropriate proceedings and for which disputed
amounts adequate reserves have been established in accordance with GAAP.

                  SECTION 4.5.  MAINTENANCE OF PROPERTIES.

                  The Company shall cause all material properties used or useful
to the conduct of its business and the business of each of its Subsidiaries to
be maintained and kept in good condition, repair and working order (reasonable
wear and tear excepted) and supplied with all necessary equipment and shall
cause to be made all necessary repairs, renewals, replacements, betterments and
improvements thereof, all as in their reasonable judgment may be necessary, so
that the business carried on in connection therewith may be properly conducted
at all times; PROVIDED, HOWEVER, that nothing in this Section 4.5 shall prevent
the Company or any Subsidiary from discontinuing any operation or maintenance of
any of such properties, or disposing of any of them, if such discontinuance or
disposal is (a), in the judgment of the Company, desirable in the conduct of the
business of such entity and (b) not disadvantageous in any material respect to
the Holders.

                  SECTION 4.6.  COMPLIANCE CERTIFICATE; NOTICE OF
DEFAULT.

                           (a)  The Company shall deliver to the Trustee

Subsidiaries during the preceding fiscal year has been made under the

Indenture and further stating, as to each such Officer signing such certificate,
whether or not the signer knows of any failure by the Company or any Subsidiary
of the Company to comply with any conditions or covenants in this Indenture and,
if such signor does know of such a failure to comply, the certificate shall
describe such failure with particularity. The certificate shall also notify the
Trustee should the relevant fiscal year end on any date other than the current
fiscal year end date.

                           (b)  The Company shall, so long as any of the
Debentures are outstanding, deliver to the Trustee, promptly upon becoming aware
of any Default, Event of Default or fact which would prohibit the making of any
payment to or by the Trustee in respect of the Debentures, an Officers'
Certificate specifying such Default, Event of Default or fact and what action
the Company is taking or proposes to take with respect thereto. The Trustee
shall not be deemed to have knowledge of any Default, any Event of Default or
any such fact unless one of its Trust Officers receives written notice thereof
from the Company or any of the Holders.

                  SECTION 4.7.  REPORTS.

                           (a)  The Company shall deliver to the Trust-

                           (b)  If the Company is required to furnish

generally, and any quarterly or other financial reports furnished by it to its
stockholders generally, promptly to be filed with the Trustee and mailed to the
Holders at their addresses appearing in the register of Securities maintained by
the Registrar.

                  SECTION 4.8.  LIMITATION ON STATUS AS INVESTMENT
COMPANY.

                  Neither the Company nor any of its Subsidiaries shall become
an "investment company" (as that term is defined in the Investment Company Act
of 1940, as amended), or otherwise become subject to regulation under the
Investment Company Act of 1940, as amended.

                  SECTION 4.9.  WAIVER OF STAY, EXTENSION OR 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 or extension law or any
usury law or other law which would prohibit or forgive the Company from paying
all or any portion of the principal of, premium of, or interest on the
Debentures as contemplated herein, wherever enacted, now or at any time
hereafter in force, or which may affect the covenants or the performance of this
Indenture; and (to the extent that it may lawfully do so) the Company hereby
expressly waives all benefit or advantage of any such law, and covenants that it
will not hinder, delay or impede the execution of any power herein granted to
the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

                              SUCCESSOR CORPORATION

                  SECTION 5.1.  LIMITATION ON MERGER, SALE OR CON-
SOLIDATION.

                           (a)  The Company shall not, directly or
indirectly, consolidate with or merge with or into another Person or sell,
lease, convey or transfer all or substantially all of its assets (computed on a
consolidated basis), whether in a single transaction or a series of related
transactions, to another Person or group of affiliated Persons, unless (i)
either (a) in the case of a merger or consolidation, the Company is the
surviving entity or (b) the resulting, surviving or transferee entity is a
corporation organized under the laws of the United States, any state thereof or
the District of Columbia and expressly assumes by supplemental indenture all of
the obligations of the Company in connection with the Debentures and this

                                       26

Indenture; (ii) no Default or Event of Default shall exist or shall occur
immediately before or after giving effect on a PRO FORMA basis to such
transaction; and (iii) the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that such consolidation,
merger or transfer and, if a supplemental indenture is required, such
supplemental indenture comply with this Indenture and that all conditions
precedent relating to such transactions have been satisfied.

                           (b)  For purposes of clause (a) of this
Section 5.1, the sale, lease, conveyance or transfer of all or substantially all
of the properties and assets of one or more Subsidiaries of the Company to a
person other than the Company or a Subsidiary of the Company, which properties
and assets, if held by the Company instead of such Subsidiaries, would
constitute all or substantially all of the properties and assets of the Company
on a consolidated basis, shall be deemed to be the transfer of all or
substantially all of the properties and assets of the Company.

                  SECTION 5.2.  SUCCESSOR CORPORATION SUBSTITUTED.

                  Upon any consolidation or merger or any sale, lease,
conveyance or transfer of all or substantially all of the assets of the Company
in accordance with the foregoing, the successor corporation formed by such
consolidation or into which the Company is merged or to which such sale, lease,
conveyance or transfer is made, shall succeed to, and be substituted for, and
may exercise every right and power of, the Company under the Indenture with the
same effect as if such successor corporation had been named therein as the
Company, and when a successor corporation duly assumes all of the obligations of
the Company pursuant hereto and pursuant to the Debentures, the predecessor
shall be released from such obligations (except with respect to any obligations
that arise from, or are related to, such transaction).

                                   ARTICLE VI

                         EVENTS OF DEFAULT AND REMEDIES

                  SECTION 6.1.  EVENTS OF DEFAULT.

"Event of Default," wherever used herein, means any one of the following events
(whatever the reason for such Event of Default and whether it shall be caused
voluntarily or involuntarily or effected, without limitation, by operation of

                                       27

                           (1) failure to pay any installment of interest upon
         the Debentures as and when the same becomes due and payable, or to
         perform any conversion of the Debentures required under this Indenture,
         and the continuance of such default for a period of 30 days, whether or
         not such payment is prohibited by Article XII;

                           (2) failure to pay all or any part of the principal
         of or premium, if any, on the Debentures when and as the same becomes
         due and payable at maturity, redemption, by acceleration or otherwise,
         including, without limitation, pursuant to any Repurchase Offer or
         otherwise, whether or not such payment is prohibited by Article XII;

                           (3) failure by the Company to observe or perform any
         covenant, agreement or warranty contained in the Debentures or this
         Indenture (other than a default in the performance of any covenant,
         agreement or warranty which is specifically dealt with elsewhere in
         this Section 6.1), and continuance of such failure for a period of 60
         days after there has been given, by registered or certified mail, to
         the Company by the Trustee, or to the Company and the Trustee by
         Holders of at least 25% in aggregate principal amount of the then
         outstanding Debentures, a written notice specifying such default or
         breach, requesting it to be remedied and stating that such notice is a
         "Notice of Default" hereunder;

                           (4) a default in the payment of principal, premium or
         interest when due which extends beyond any stated period of grace
         applicable thereto or an acceleration for any other reason of the
         maturity of any Indebtedness (other than Limited Recourse Indebtedness,
         unless such default or acceleration results in any other Indebtedness
         (other than Limited Recourse Indebtedness) with an aggregate principal
         amount in excess of $10,000,000.00 being accelerated or otherwise
         becoming due and payable) of the Company or any of its Subsidiaries
         with an aggregate principal amount in excess of $10,000,000.00;

                                       28

                           (5)  the Company or any Significant
         Subsidiary of the Company pursuant to or within the
         meaning of any Bankruptcy Law:

                           (A)      commences a voluntary case or
                  proceeding;

                           (B)      consents to the entry of an order for
                  relief against it in an involuntary case or
                  proceeding;

                           (C)      consents to the appointment of a
                  Custodian of it or for all or for a substantial
                  part of its property;

                           (D)      makes a general assignment for the
                  benefit of its creditors; or

                           (E) fails to contest any involuntary case or
                  proceeding filed against it within the time period fixed by
                  any applicable rules, and any extensions granted by the court
                  where such involuntary case or proceeding is pending;

                           (6) a court of competent jurisdiction enters an order
         or decree under any Bankruptcy Law that remains unstayed and in effect
         for 60 days and that:

                           (A)      is for relief against the Company or any
                  Significant Subsidiary of the Company in an
                  involuntary case or proceeding;

                           (B) appoints a Custodian of the Company or any
                  Significant Subsidiary of the Company or a Custodian for all
                  or for a substantial part of the property of the Company or
                  any Significant Subsidiary of the Company; or

                           (C)      orders the liquidation of the Company or
                  any Significant Subsidiary of the Company;

                           (7) final unsatisfied judgments not covered by
         insurance for the payment of money, or the issuance of any warrant of
         attachment against any portion of the property or assets of the Company
         or any of its Subsidiaries, aggregating in excess of $10,000,000.00 at
         any one time rendered against the Company or any of its Subsidiaries
         and not stayed, bonded or discharged for a

                                       29

         period (during which execution shall not be effectively stayed) of 75
         days (or, in the case of any such final judgment which provides for
         payment over time, which shall so remain unstayed, unbonded or
         undischarged beyond any applicable payment date provided therein).

                  Notwithstanding the 60-day period and notice requirement
contained in Section 6.1(3) above, with respect to a default under Article XI
the 60-day period referred to in Section 6.1(3) shall be deemed to have begun as
of the date the Repurchase Event notice is required to be sent in the event that
the Company has not complied with the provisions of Section 11.1 and the Trustee
or Holders of at least 25% in principal amount of the outstanding Debentures
thereafter give the Notice of Default referred to in Section 6.1(3) to the
Company and, if applicable, the Trustee; PROVIDED, HOWEVER, that if the breach
or default is a result of a default in the payment when due of the Repurchase
Payment on the Repurchase Payment Date, such Event of Default shall be deemed,
for purposes of this Section 6.1, to arise no later than on the Repurchase
Payment Date .

                  SECTION 6.2.  ACCELERATION OF MATURITY DATE; RE-
SCISSION AND ANNULMENT.

                  If an Event of Default (other than an Event of Default
specified in Section 6.1(5) or (6) relating to the Company) occurs and is
continuing, then, and in every such case, unless the principal of all of the
Debentures shall have already become due and payable, either the Trustee or the
Holders of not less than 25% in aggregate principal amount of then outstanding
Debentures, by a notice in writing to the Company (and to the Trustee if given
by Holders) (an "Acceleration Notice"), may declare all of the principal of the
Debentures (or the Repurchase Payment if the Event of Default includes failure
to pay the Repurchase Payment), including in each case accrued interest thereon,
to be due and payable immediately. In the event a declaration of acceleration
resulting from an Event of Default described in Section 6.1(4) above has
occurred and is continuing, such declaration of acceleration shall be
automatically annulled if such default is cured or waived or the holders of the
Indebtedness which is the subject of such default have rescinded their
declaration of acceleration in respect of such Indebtedness within 60 days
thereof and the Trustee has received written notice of such cure, waiver or
rescission and no other Event of Default described in Section 6.1(4) above has
occurred that has not been cured or

                                       30

waived within 60 days of the declaration of such acceleration in respect of such
Indebtedness. If an Event of Default specified in Section 6.1(5) or (6) relating
to the Company occurs, all principal and accrued interest thereon will be
immediately due and payable on all outstanding Debentures without any
declaration or other act on the part of Trustee or the Holders.

                  At any time after such a declaration of acceleration is made
and before a judgment or decree for payment of the money due has been obtained
by the Trustee as hereinafter provided in this Article VI, the Holders of a
majority in aggregate principal amount of then outstanding Debentures, by
written notice to the Company and the Trustee, may rescind, on behalf of all
Holders, any such declaration of acceleration if all Events of Default, other
than the non-payment of the principal of, premium, if any, and interest on
Debentures which have become due solely by such declaration of acceleration,
have been cured or waived as provided in Section 6.12 and all sums paid or
advanced by the Trustee and any other amounts due the Trustee under Section 7.7
have been paid to the Trustee. Notwithstanding the previous sentence of this
Section 6.2, no waiver shall be effective against any Holder for any Event of
Default or event which with notice or lapse of time or both would be an Event of
Default with respect to any covenant or provision which cannot be modified or
amended without the consent of the Holder of each outstanding Debenture affected
thereby, unless all such affected Holders agree, in writing, to waive such Event
of Default or other event. No such waiver shall cure or waive any subsequent
default or impair any right consequent thereon.

                  SECTION 6.3.  COLLECTION OF INDEBTEDNESS AND SUITS
FOR ENFORCEMENT BY TRUSTEE.

                  The Company covenants that if an Event of Default in payment
of principal, premium, or interest specified in clause (1) or (2) of Section 6.1
occurs and is continuing, the Company shall, upon demand of the Trustee, pay to
it, for the benefit of the Holders of such Debentures, the whole amount then due
and payable on such Debentures for principal, premium (if any) and interest,
and, to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal (and premium, if any) and on any overdue
interest, at the rate borne by the Debentures, and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of

                                       31

collection, including compensation to, and expenses, disbursements and advances
of the Trustee, its agents and counsel, and any other amounts due to the Trustee
under Section 7.7.

                  If the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust in favor
of the Holders, may institute a judicial proceeding for the collection of the
sums so due and unpaid, may prosecute such proceeding to judgment or final
decree and may enforce the same against the Company or any other obligor upon
the Debentures and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Company or any other obligor
upon the Debentures, wherever situated.

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

                  SECTION 6.4.  TRUSTEE MAY FILE PROOFS OF CLAIM.

                  In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other judicial proceeding relative to the Company or any other obligor upon the
Debentures or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Debentures
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise to take any and
all actions under the TIA, including

                           (1)  to file and prove a claim for the whole
amount of principal (and premium, if any) and interest owing and unpaid in
respect of the Debentures and to file such other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee (including any
claim for the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agent and counsel,

                                       32

and any other amounts due to the Trustee under Section 7.7)
and of the Holders allowed in such judicial proceeding, and

                           (2)  to collect and receive any moneys or
other property payable or deliverable on any such claims and
to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.7.

                  Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment, or composition affecting
the Debentures or the rights of any Holder thereof or to authorize the Trustee
to vote in respect of the claim of any Holder in any such proceeding.

                  SECTION 6.5.  TRUSTEE MAY ENFORCE CLAIMS WITHOUT
POSSESSION OF THE DEBENTURES.

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

                  SECTION 6.6.  PRIORITIES.

                  Any money collected by the Trustee pursuant to this Article VI
shall be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal,
premium (if any) or interest, upon presentation of the Debentures

                                       33

and the notation thereon of the payment if only partially paid and upon
surrender thereof if fully paid:

                  FIRST:  To the Trustee in payment of all amounts
due pursuant to Section 7.7;

                  SECOND:  To the Holders of Senior Indebtedness of
the Company to the extent provided in Article XII;

                  THIRD: To the Holders in payment of the amounts then due and
unpaid for principal of, premium (if any) and interest on, the Debentures in
respect of which or for the benefit of which such money has been collected,
ratably, without preference or priority of any kind, according to the amounts
due and payable on such Debentures for principal, premium (if any) and interest,
respectively; and

                  FOURTH:  To whomsoever may be lawfully entitled
thereto, the remainder, if any.

                  SECTION 6.7.  LIMITATION ON SUITS.

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

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

                     (B) the Holders of not less than 25% in
         principal amount of then outstanding Debentures shall have made written
         request to the Trustee to institute proceedings in respect of such
         Event of Default in its own name as Trustee hereunder;

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

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

                                       34

                     (E) no direction inconsistent with such
         written request has been given to the Trustee during such 60-day period
         by the Holders of a majority in principal amount of the outstanding
         Debentures;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

                  SECTION 6.8.  UNCONDITIONAL RIGHT OF HOLDERS TO
RECEIVE PRINCIPAL, PREMIUM AND INTEREST.

                  Notwithstanding any other provision of this Indenture, the
Holder of any Debenture shall have the right, which is absolute and
unconditional, to receive payment of the principal of, and premium (if any) and
interest on, such Debenture when due (including, in the case of redemption, the
Redemption Price on the applicable Redemption Date, and in the case of the
Repurchase Payment, on the applicable Repurchase Payment Date) and to institute
suit for the enforcement of any such payment after such respective dates, and
such rights shall not be impaired without the consent of such Holder.

                  SECTION 6.9.  RIGHTS AND REMEDIES CUMULATIVE.

                  Except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Debentures in Section 2.7, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

                  SECTION 6.10.  DELAY OR OMISSION NOT WAIVER.

                  No delay or omission by the Trustee or by any
Holder of any Debenture to exercise any right or remedy

                                       35

arising upon any Event of Default shall impair the exercise of any such right or
remedy or constitute a waiver of any such Event of Default. Every right and
remedy given by this Article VI or by law to the Trustee or to the Holders may
be exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders, as the case may be.

                  SECTION 6.11.  CONTROL BY HOLDERS.

                  The Holder or Holders of a majority in aggregate principal
amount of then outstanding Debentures shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee or exercising any trust or power conferred upon the Trustee, PROVIDED,
that

                           (1) such direction shall not be in conflict with any
         rule of law or with this Indenture or involve the Trustee in any
         personal liability,

                           (2) the Trustee shall not determine that the action
         so directed would be unjustly prejudicial to the Holders not taking
         part in such direction, and

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

                  SECTION 6.12.  WAIVER OF PAST DEFAULT.

                  Subject to Section 6.8, the Holder or Holders of not less than
a majority in aggregate principal amount of the outstanding Debentures may, on
behalf of all Holders, prior to the declaration of the maturity of the
Debentures, waive any past default hereunder and its consequences, except a
default

                     (A) in the payment of the principal of,
         premium, if any, or interest on, any Debenture as
         specified in clauses (1) and (2) of Section 6.01, or

                     (B) in respect of a covenant or provi-
         sion hereof which, under Article IX, cannot be modified or amended
         without the consent of the Holder of each outstanding Debenture
         affected.

                                       36

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

                  SECTION 6.13.  UNDERTAKING FOR COSTS.

                  All parties to this Indenture agree, and each Holder of any
Debenture by his acceptance thereof shall be deemed to have agreed, that any
court may in its discretion require, in any suit for the enforcement of any
right or remedy under this Indenture, or in any suit against the Trustee for any
action taken, suffered or omitted to be taken by it as Trustee, the filing by
any party litigant in such suit of an undertaking to pay the costs of such suit,
and that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in such suit, having due
regard to the merits and good faith of the claims or defenses made by such party
litigant; but the provisions of this Section 6.13 shall not apply to any suit
instituted by the Company, to any suit instituted by the Trustee, to any suit
instituted by any Holder, or group of Holders, holding in the aggregate more
than 10% in aggregate principal amount of the outstanding Debentures, or to any
suit instituted by any Holder for enforcement of the payment of principal of, or
premium (if any) or interest on, any Debenture on or after the respective
Maturity Date expressed in such Debenture (including, in the case of redemption,
on or after the Redemption Date).

                  SECTION 6.14.  RESTORATION OF RIGHTS AND REMEDIES.

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

                                       37

                                   ARTICLE VII

                                     TRUSTEE

                  The Trustee hereby accepts the trust imposed upon it by this
Indenture and covenants and agrees to perform the same, as herein expressed.

                  SECTION 7.1.  DUTIES OF TRUSTEE.

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

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

                           (1) The Trustee need perform only those duties as are
         specifically set forth in this Indenture and no others, and no
         covenants or obligations shall be implied in or read into this
         Indenture which are adverse to the Trustee.

                           (2) In the absence of bad faith on its part, the
         Trustee may conclusively rely, as to the truth of the statements and
         the correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and, if required by the terms hereof,
         conforming to the requirements of this Indenture. However, the Trustee
         shall examine the certificates and opinions which by any provision
         hereof are specifically required to be furnished to the Trustee 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:

                           (1) This paragraph does not limit the effect of
         paragraph (b) of this Section 7.1.

                           (2)  The Trustee shall not be liable for any
         error of judgment made in good faith by a Trust Offi-

                                       38

         cer, unless it is proved that the Trustee was negligent
         in ascertaining the pertinent facts.

                           (3) The Trustee shall not be liable with respect to
         any action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 6.11.

                           (d)  No provision of this Indenture shall
require the Trustee to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its duties hereunder or to take
or omit to take any action under this Indenture or at the request, order or
direction of the Holders or in the exercise of any of its rights or powers if it
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it.

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

                           (f)  The Trustee shall not be liable for
interest on any assets received by it except as the Trustee may agree in writing
with the Company. Assets held in trust by the Trustee need not be segregated
from other assets except to the extent required by law.

                  SECTION 7.2.  RIGHTS OF TRUSTEE.

                  Subject to Section 7.1:

                           (a)  The Trustee may rely on any document
believed by it to be genuine and to have been signed or presented by the proper
Person. The Trustee need not investigate any fact or matter stated in the
document.

                           (b)  Before the Trustee acts or refrains from
acting, it may consult with counsel and may require an Officers' Certificate or
an Opinion of Counsel, which shall conform to Sections 14.4 and 14.5. The
Trustee shall not be liable for any action it takes or omits to take in good
faith in reliance on such certificate or advice of counsel.

                           (c)  The Trustee may act through its attor-
neys and agents and shall not be responsible for the misconduct or negligence of
any agent appointed with due care.

                                       39

                           (d)  The Trustee shall not be liable for any
action it takes or omits to take in good faith which it believes to be
authorized or within its rights or powers conferred upon it by this Indenture.

                           (e)  The Trustee shall not be bound to make
any investigation into the facts or matters stated in any resolution,
certificate, statement, instrument, opinion, notice, request, direction,
consent, order, bond, debenture, or other paper or document, but the Trustee, in
its discretion, may make such further inquiry or investigation into such facts
or matters as it may see fit, and, if the Trustee shall determine to make such
further inquiry or investigation, it shall be entitled to examine the books,
records and premises of the Company, personally or by agent or attorney.

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

                           (g)  Unless otherwise specifically provided
for in this Indenture, any demand, request, direction as notice from the Company
shall be sufficient if signed by an Officer of the Company.

                           (h)  The Trustee shall have no duty to in-
quire as to the performance of the Company's covenants in Article IV hereof. In
addition, the Trustee shall not be deemed to have knowledge of any Default or
Event of Default except (i) any Event of Default occurring pursuant to Sections
6.1(1) or 6.1(2) or (ii) any Default or Event of Default of which the Trustee
shall have received written notification or a Trust Officer shall have obtained
actual knowledge.

                  SECTION 7.3.  INDIVIDUAL RIGHTS OF TRUSTEE.

                  The Trustee in its individual or any other capacity may become
the owner or pledgee of Debentures and may otherwise deal with the Company, any
of its Subsidiaries, or their respective Affiliates with the same rights it
would have if it were not Trustee. Any Agent may do the same with

                                       40

like rights.  However, the Trustee must comply with Sections
7.10 and 7.11.

                  SECTION 7.4.  TRUSTEE'S DISCLAIMER.

                  The Trustee makes no representation as to the validity or
adequacy of this Indenture or the Debentures and it shall not be accountable for
the Company's use of the proceeds from the Debentures, and it shall not be
responsible for any statement in the Debentures, other than the Trustee's
certificate of authentication, or the use or application of any funds received
by a Paying Agent other than the Trustee.

                  SECTION 7.5.  NOTICE OF DEFAULT.

                  If a Default or an Event of Default occurs and is continuing
and if it is known to the Trustee, the Trustee shall mail to each Securityholder
notice of the uncured Default or Event of Default within 90 days after such
Default or Event of Default occurs. Except in the case of a Default or an Event
of Default in payment of principal (or premium, if any) of, or interest on, any
Debenture (including the payment of the Repurchase Payment on the Repurchase
Payment Date, and the payment of the Redemption Price on the Redemption Date),
the Trustee may withhold the notice if and so long as a Trust Officer in good
faith determines that withholding the notice is in the interest of the
Securityholders.

                  SECTION 7.6.  REPORTS BY TRUSTEE TO HOLDERS.

                  On or about May 15 of each year, beginning with May 15, 1996,
the Trustee shall, if required by law, mail to each Securityholder a brief
report dated as of such date that complies with TIA ss. 313(a). The Trustee also
shall comply with TIA ss.ss. 313(b) and 313(c).

                  The Company shall promptly notify the Trustee in writing if
the Debentures become listed on any stock exchange or automated quotation
system.

                  A copy of each report at the time of its mailing to
Securityholders shall be mailed to the Company and filed with the SEC and each
stock exchange, if any, on which the Debentures are listed.

                                       41

                  SECTION 7.7.  COMPENSATION AND INDEMNITY.

                  The Company agrees to pay to the Trustee from time to time
reasonable compensation for its services. 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
disbursements, expenses and advances incurred or made by it. Such expenses shall
include the reasonable compensation, disbursements and expenses of the Trustee's
agents, accountants, experts and counsel.

                  The Company agrees to indemnify the Trustee and each of its
officers, directors, attorneys-in-fact and agents for, and hold it harmless
against, any claim, demand, expense (including but not limited to reasonable
compensation, disbursements and expenses of the Trustee's agents and counsel),
loss or liability incurred by it without negligence or bad faith on its part,
arising out of or in connection with the administration of this trust and its
rights or duties hereunder including the reasonable costs and expenses of
defending itself against any claim or liability in connection with the exercise
or performance of any of its powers or duties hereunder. The Trustee shall
notify the Company promptly of any claim asserted against the Trustee for which
it may seek indemnity. The Company may defend the claim and the Trustee shall
provide reasonable cooperation at the Company's expense in the defense. The
Trustee may have separate counsel and the Company shall pay the reasonable fees
and expenses of such counsel. The Company need not pay for any settlement made
without its written consent. The Company need not reimburse any expense or
indemnify against any loss or liability to the extent incurred by the Trustee
through its negligence, bad faith or willful misconduct.

                  To secure the Company's payment obligations in this Section
7.7, the Trustee shall have a lien prior to the Debentures on all assets held or
collected by the Trustee, in its capacity as Trustee, except assets held in
trust to pay principal and premium, if any, of or interest on particular
Debentures.

                  When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.1(5) or (6) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

                                       42


                  The Company's obligations under this Section 7.7 and any lien
arising hereunder shall survive the resignation or removal of the Trustee, the
discharge of the Company's obligations pursuant to Article VIII of this
Indenture and any rejection or termination of this Indenture under any
Bankruptcy Law.

                  SECTION 7.8.  REPLACEMENT OF TRUSTEE.

                  A resignation or removal of the 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 in writing.
The Holder or Holders of a majority in principal amount of the outstanding
Debentures may remove the Trustee by so notifying the Company and the Trustee in
writing and may appoint a successor trustee with the Company's consent. The
Company may remove the Trustee if:

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

                           (b)      the Trustee is adjudged bankrupt or
insolvent;

                           (c)      a receiver, Custodian, or other 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
Holder or Holders of a majority in principal amount of the Debentures may
appoint a successor Trustee to replace the successor Trustee appointed by the
Company.

                  A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after that
and provided that all sums owing to the Trustee provided for in Section 7.7 have
been paid, the retiring Trustee shall transfer all property held by it as
trustee to the successor Trustee, subject to the lien provided in Section 7.7,
the resignation or removal of the retiring Trustee shall become effective, and
the successor Trustee shall have all the rights, powers and duties of

                                       43

the Trustee under this Indenture.  A successor Trustee shall
mail notice of its succession to each Holder.

                  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 Holder or Holders of at least 10% in principal amount of the
outstanding Debentures may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

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

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

                  SECTION 7.9.  SUCCESSOR TRUSTEE BY MERGER, ETC.

                  If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation, the resulting, surviving or transferee corporation without any
further act shall, if such resulting, surviving or transferee corporation is
otherwise eligible hereunder, be the successor Trustee.

                  SECTION 7.10.  ELIGIBILITY; DISQUALIFICATION.

                  The Trustee shall at all times satisfy the requirements of TIA
ss. 310(a)(1), (2) and (5). The Trustee shall have a combined capital and
surplus of at least $100,000,000 as set forth in its most recent published
annual report of condition. The Trustee shall comply with TIA ss. 310(b).

                  SECTION 7.11.  PREFERENTIAL COLLECTION OF CLAIMS
AGAINST COMPANY.

                  The Trustee shall comply with TIA ss. 311(a), excluding any
creditor relationship listed in TIA ss. 311(b). A Trustee who has resigned or
been removed shall be subject to TIA ss. 311(a) to the extent indicated.

                                       44

                                  ARTICLE VIII

                           SATISFACTION AND DISCHARGE

                  SECTION 8.1.  SATISFACTION AND DISCHARGE OF IN-
DENTURE.

                  The Company may terminate its obligations under this Indenture
(subject to the provisions of this Article VIII) when it shall have delivered to
the Trustee for cancellation all Debentures theretofore authenticated (other
than any Debentures which shall have been destroyed, lost or stolen and which
shall have been replaced or paid as provided in Article II hereof) and the
following conditions shall be satisfied:

                           (1)  The Company has paid all sums payable
under the Indenture; and

                           (2)  The Company shall have delivered to the
Trustee an Officers' Certificate and an Opinion of Counsel, each stating that
all conditions precedent have been complied with as contemplated by this Section
8.1.

                  SECTION 8.2.  REPAYMENT TO THE COMPANY.

                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, for the payment of the principal of, premium, if any,
or interest on any Debenture and remaining unclaimed for two years after such
principal, and premium, if any, or interest has become due and payable shall be
paid to the Company on its request; and the Holder of such Debenture shall
thereafter look only to the Company for payment thereof, and all liability of
the Trustee or such Paying Agent with respect to such trust money shall
thereupon cease; PROVIDED, HOWEVER, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the
Company cause to be published once, in the NEW YORK TIMES and THE WALL STREET
JOURNAL (national edition), notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the
date of such notification or publication, any unclaimed balance of such money
then remaining will be repaid to the Company.

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

                  SECTION 9.1.  SUPPLEMENTAL INDENTURES WITHOUT
CONSENT OF HOLDERS.

                  Without the consent of any Holder, the Company, when
authorized by Board Resolutions, and the Trustee, at any time and from time to
time, may enter into one or more indentures supplemental hereto, in form
satisfactory to the Trustee, for any of the following purposes:

                           (1)      to cure any ambiguity, defect, or incon-
sistency, or to make any other provisions with respect to matters or questions
arising under this Indenture which shall not be inconsistent with the provisions
of this Indenture, PROVIDED, that the Company has delivered to the Trustee an
Opinion of Counsel stating that such action pursuant to this clause (1) does not
adversely affect the interests of any Holder in any respect;

                           (2)      to create additional covenants of the
Company for the benefit of the Holders, or to surrender any right or power
herein conferred upon the Company or to make any other change that does not
adversely affect the rights of any Holder, PROVIDED, that the Company has
delivered to the Trustee an Opinion of Counsel stating that such change pursuant
to this clause (2) does not adversely affect the rights of any Holder;

                           (3)      to provide for collateral for or guaran-
tors of the Debentures;

                           (4)      to evidence the succession of another
Person to the Company and the assumption by any such successor of the
obligations of the Company herein and in the Debentures in accordance with
Article V; or

                           (5)      to comply with the TIA.

                  SECTION 9.2.  AMENDMENTS, SUPPLEMENTAL INDENTURES
AND WAIVERS WITH CONSENT OF HOLDERS.

                  Subject to Section 6.8 and the last sentence of this
paragraph, with the consent of the Holders of not less than a majority in
aggregate principal amount of then outstanding Debentures, by written act of
said Holders deliv-

                                       46

ered to the Company and the Trustee, the Company, when authorized by Board
Resolutions, and the Trustee may amend or supplement this Indenture or the
Debentures or enter into an indenture or indentures supplemental hereto for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Indenture or the Debentures or of modifying in any
manner the rights of the Holders under this Indenture or the Debentures. Subject
to Section 6.8 and the last sentence of this paragraph, the Holder or Holders of
not less than a majority in aggregate principal amount of then outstanding
Debentures may, in writing, waive compliance by the Company with any provision
of this Indenture or the Debentures. Notwithstanding any of the above, however,
no such amendment, supplemental indenture or waiver shall, without the consent
of the Holder of each outstanding Debenture affected thereby:

                  (1) reduce the percentage of principal amount of Debentures
whose Holders must consent to an amendment, supplement or waiver of any
provision of this Indenture or the Debentures;

                  (2)      reduce the rate or extend the time for pay-
ment of interest on any Debenture;

                  (3)      reduce the principal amount of any Debenture,
or reduce the Repurchase Payment or the Redemption Price;

                  (4)      change the Stated Maturity of any Debenture;

                  (5) alter the redemption provisions of Article III, the
provisions of Article XI, Article XII or Article XIII, or the Conversion Price,
in any case in a manner adverse to any Holder;

                  (6) make any changes in the provisions concerning waivers by
Holders of the Debentures (including waivers of Defaults or Events of Default)
or the provisions of this third sentence of Section 9.2 (except to increase any
required percentage or to provide that certain other provisions of this
Indenture cannot be modified or waived without the consent of the Holder of each
outstanding Debenture affected thereby) or impair the rights of Holders to
institute suit for the enforcement of any payments due under this Indenture or
the conversion of any Debenture; or

                                       47

                  (7) make the principal of, or the interest on, any Debenture
payable with anything or in any manner other than as provided for in this
Indenture (including changing the place of payment where, or the coin or
currency in which, any Debenture or any premium or the interest thereon is
payable) and the Debentures as in effect on the date hereof.

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

                  After an amendment, supplement or waiver under this Section
becomes effective, the Company shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such supplemental indenture or
waiver.

                  After an amendment, supplement or waiver under this Section
9.2 or Section 9.4 becomes effective, it shall bind each Holder.

                  In connection with any amendment, supplement or waiver under
this Article IX or under Section 6.12, the Company may, but shall not be
obligated to, offer to any Holder who consents to such amendment, supplement or
waiver, or (at the option of the Company) to all Holders, consideration for
consent to such amendment, supplement or waiver, and may offer to purchase or
exchange consideration for such Holder's Debenture in connection with obtaining
such consent.

                  SECTION 9.3.  COMPLIANCE WITH TIA.

                  Every amendment, waiver or supplement of this Indenture or the
Debentures shall comply with the TIA as then in effect.

                  SECTION 9.4.  REVOCATION AND EFFECT OF CONSENTS.

                  Until an amendment, waiver or supplement becomes effective, a
consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder of a Debenture or portion of a Debenture that evidences the
same

                                       48

debt as the consenting Holder's Debenture, even if notation of the consent is
not made on any Debenture. However, any such Holder or subsequent Holder may
revoke the consent as to his Debenture or portion of his Debenture by written
notice to the Company or the Person designated by the Company as the Person to
whom consents should be sent if such revocation is received by the Company or
such Person before the date on which the Trustee receives an Officers'
Certificate certifying that the Holders of the requisite principal amount of
Debentures have consented (and not theretofore revoked such consent) 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 Holders entitled to consent to any
amendment, supplement or waiver, which record date shall be the date so fixed by
the Company notwithstanding the provisions of the TIA. If a record date is
fixed, then notwithstanding the last sentence of the immediately preceding
paragraph, those Persons who were Holders at such record date, and only those
Persons (or their duly designated proxies), shall be entitled to revoke any
consent previously given, whether or not such Persons continue to be Holders
after such record date. No such consent shall be valid or effective for more
than 90 days after such record date.

                  After an amendment, supplement or waiver becomes effective, it
shall bind every Securityholder, unless it makes a change described in any of
clauses (1) through (7) of Section 9.2.

                  SECTION 9.5.  NOTATION ON OR EXCHANGE OF
DEBENTURES.

                  If an amendment, supplement or waiver changes the terms of a
Debenture, the Trustee may require the Holder of the Debenture to deliver it to
the Trustee or require the Holder to put an appropriate notation on the
Debenture. The Trustee may place an appropriate notation on the Debenture about
the changed terms and return it to the Holder. Alternatively, if the Company or
the Trustee so determines, the Company in exchange for the Debenture shall issue
and the Trustee shall authenticate a new Debenture that reflects the changed
terms. Any failure to make the appropriate notation or to issue a new Debenture
shall not affect the validity of such amendment, supplement or waiver.

                                       49

                  SECTION 9.6.  TRUSTEE TO SIGN AMENDMENTS, ETC.

                  The Trustee shall execute any amendment, supplement or waiver
authorized pursuant to this Article IX; PROVIDED, that the Trustee may, but
shall not be obligated to, execute any such amendment, supplement or waiver
which affects the Trustee's own rights, duties or immunities under this
Indenture. The Trustee shall be entitled to receive, and shall be fully
protected in relying upon, in addition to the documents required by Section
14.4, an Opinion of Counsel stating that the execution of any amendment,
supplement or waiver is authorized or permitted by this Indenture.

                                    ARTICLE X

from time to time pursuant to the provisions of this Article X for any of the
following purposes:

                           (a)  to give any notice to the Company or to
the Trustee, or to give any directions to the Trustee, or to waive or to consent
to the waiving of any Default or Event of Default hereunder and its
consequences, or to take any other action authorized to be taken by
Securityholders pursuant to any of the provisions of Article VI;

                           (b)  to remove the Trustee or appoint a
successor Trustee pursuant to the provisions of Article VII;

                           (c)  to consent to an amendment, supplement
or waiver pursuant to the provisions of Section 9.2; or

                           (d)  to take any other action (i) authorized
to be taken by or on behalf of the Holder or Holders of any specified aggregate
principal amount of the Debentures under any other provision of this Indenture,
or authorized or permitted by law or (ii) which the Trustee deems necessary or
appropriate in connection with the administration of this Indenture.

                  SECTION 10.2.  MANNER OF CALLING MEETINGS.

                  The Trustee may at any time call a meeting of Securityholders
to take any action specified in Section 10.1, to be held at such time and at
such place in the City of New York, New York or elsewhere as the Trustee shall
determine. Notice of every meeting of Securityholders, setting forth the time

the Company and to the Holders at their last addresses as they shall appear on
the registration books of the Registrar, not less than 10 nor more than 60 days
prior to the date fixed for a meeting.

                  Any meeting of Securityholders shall be valid without notice
if the Holders of all Debentures then outstanding are present in Person or by
proxy, or if notice is waived before or after the meeting by the Holders of all
Debentures outstanding, and if the Company and the Trustee are either present by
duly authorized representatives or have, before or after the meeting, waived
notice.

                  SECTION 10.3.  CALL OF MEETINGS BY THE COMPANY OR
HOLDERS.

                  In case at any time the Company or the Holders of not less
than 10% in aggregate principal amount of the Debentures then outstanding, shall
have requested the Trustee to call a meeting of Securityholders to take any
action specified in Section 10.1, by written request setting forth in reasonable
detail the action proposed to be taken at the meeting, and the Trustee shall not
have mailed the notice of such meeting within 20 days after receipt of such
request, then the Company or the Holders of Debentures in the amount above

elsewhere for such meeting and may call such meeting for the purpose of taking
such action, by mailing or causing to be mailed notice thereof as provided in
Section 10.2, or by causing notice thereof to be published at least once in each

at least five days a week of a general circulation in The City of New York,
State of New York, the first such publication to be not less than 10 nor more

                  SECTION 10.4.  WHO MAY ATTEND AND VOTE AT MEET-
INGS.

                  To be entitled to vote at any meeting of Securityholders, a
Person shall (a) be a registered Holder of one or more Debentures, or (b) be a
Person appointed by an instrument in writing as proxy for the registered Holder
or Holders of Debentures. The only Persons who shall be entitled to be present
or to speak at any meeting of Securityholders shall be the Persons entitled to
vote at such meeting and their counsel and any representatives of the Trustee
and its counsel and any representatives of the Company, and its counsel.

                  SECTION 10.5.  REGULATIONS MAY BE MADE BY TRUSTEE;
CONDUCT OF THE MEETING; VOTING RIGHTS; ADJOURNMENT.

                  Notwithstanding any other provision of this Indenture, the
Trustee may make such reasonable regulations as it may deem advisable for any
action by or any meeting of Securityholders, in regard to proof of the holding
of Debentures and of the appointment of proxies, and in regard to the
appointment and duties of inspectors of votes, and submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall think appropriate.
Such regulations may fix a record date and time for determining the Holders of
record of Debentures entitled to vote at such meeting, in which case those and
only those Persons who are Holders of Debentures at the record date and time so
fixed, or their proxies, shall be entitled to vote at such meeting whether or
not they shall be such Holders at the time of the meeting.

                  The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Securityholders as provided in Section 10.3, in which case the
Company or the Securityholders calling the meeting, as the case may be, shall in
like manner appoint a temporary chairman. A permanent chairman and a permanent
secretary of the meeting shall be elected by vote of the Holders of a majority
in principal amount of the Debentures represented at the meeting and entitled to
vote.

                  At any meeting each Securityholder or proxy shall be entitled
to one vote for each $1,000 principal amount of Debentures held or represented
by him; PROVIDED, HOWEVER,

                                       52

that no vote shall be cast or counted at any meeting in respect of any
Debentures challenged as not outstanding and ruled by the chairman of the
meeting to be not then outstanding. The chairman of the meeting shall have no
right to vote other than by virtue of Debentures held by him or instruments in
writing as aforesaid duly designating him as the proxy to vote on behalf of
other Securityholders. Any meeting of Securityholders duly called pursuant to
the provisions of Section 10.2 or Section 10.3 may be adjourned from time to
time by vote of the Holder or Holders of a majority in aggregate principal
amount of the Debentures represented at the meeting and entitled to vote, and
the meeting may be held as so adjourned without further notice.

                  SECTION 10.6.  VOTING AT THE MEETING AND RECORD TO
BE KEPT.

                  The vote upon any resolution submitted to any meeting of
Securityholders shall be by written ballots on which shall be subscribed the
signatures of the Holders of Debentures or of their representatives by proxy and
the principal amount of the Debentures voted by the ballot. The permanent
chairman of the meeting shall appoint two inspectors of votes, who shall count
all votes cast at the meeting for or against any resolution and who shall make
and file with the secretary of the meeting their verified written reports in
duplicate of all votes cast at the meeting. A record in duplicate of the
proceedings of each meeting of Securityholders shall be prepared by the
secretary of the meeting and there shall be attached to such record the original
reports of the inspectors of votes on any vote by ballot taken thereat and
affidavits by one or more Persons having knowledge of the facts, setting forth a
copy of the notice of the meeting and showing that such notice was mailed as
provided in Section 10.2 or published as provided in Section 10.3. The record
shall be signed and verified by the affidavits of the permanent chairman and the
secretary of the meeting and one of the duplicates shall be delivered to the
Company and the other to the Trustee to be preserved by the Trustee, the latter
to have attached thereto the ballots voted at the meeting.

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

                  SECTION 10.7.  EXERCISE OF RIGHTS OF TRUSTEE OR
SECURITYHOLDERS MAY NOT BE HINDERED OR DELAYED BY CALL OF
MEETING.

                  Nothing contained in this Article X shall be deemed or
construed to authorize or permit, by reason of any call of a meeting of
Securityholders or any rights expressly or impliedly conferred hereunder to make
such call, any hindrance or delay in the exercise of any right or rights
conferred upon or reserved to the Trustee or to the Securityholders under any of
the provisions of this Indenture or of the Debentures.

                           RIGHT TO REQUIRE REPURCHASE

                  SECTION 11.1.  REPURCHASE OF DEBENTURES AT OPTION
OF THE HOLDER.

                           (a)  In the event that a Repurchase Event oc-
curs, each Holder shall have the right, at such Holder's option, pursuant to an
irrevocable and unconditional offer by the Company and subject to the terms and
conditions of this Indenture, to require the Company to repurchase all or any
part of such Holder's Debentures (provided, that the principal amount of such
Debentures must be $1,000 or an integral multiple thereof) on the date
determined by the Company (the "Repurchase Payment Date") that is no later than
45 Business Days after the occurrence of such Repurchase Event, at a cash price
(the "Repurchase Payment") equal to 100% of the principal amount thereof, plus
accrued and unpaid interest to the Repurchase Payment Date.

                  A "Repurchase Event" will be deemed to have occurred at such
time as (i) there is a Change of Control, or (ii) the Common Stock is not listed
for trading on a United States national securities exchange or the NASDAQ
National Market System.

                           (b)  In the event that, pursuant to this
Section 11.1, the Company shall be required to commence an offer to purchase
Debentures (a "Repurchase Offer"), the Company shall follow the procedures set
forth in this Section 11.1 as follows:

                                       54

                           (1)  the Repurchase Offer shall commence
         within 15 Business Days following the Repurchase Event;


                           (2) the Repurchase Offer shall remain open for no
         fewer than 10 nor more than 20 Business Days, except to the extent that
         a longer period is required by applicable law (the "Repurchase Offer
         Period");

                           (3) upon the expiration of a Repurchase Offer, the
         Company shall purchase all of the properly tendered Debentures at the
         Repurchase Payment, including accrued and unpaid interest to the
         Repurchase Payment Date;

                           (4) if the Repurchase 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 Debenture is registered at the close of business on such record
         date, and no additional interest will be payable to Securityholders who
         tender Debentures pursuant to the Repurchase Offer;

                           (5) the Company shall provide the Trustee with notice
         of the Repurchase Offer at least 5 Business Days before the
         commencement of any Repurchase Offer; and

                           (6) on or before the commencement of any Repurchase
         Offer, the Company or the Trustee (upon the request and at the expense
         of the Company) shall send, by first-class mail, a notice prepared by
         the Company to each of the Securityholders, which (to the extent
         consistent with this Indenture) shall govern the terms of the
         Repurchase Offer and shall state:

                     (i) that the Repurchase Offer is being
         made pursuant to such notice and this Section 11.1 and that all
         Debentures, or portions thereof, tendered will be accepted for payment;

                     (ii) the Repurchase Payment (including
         the amount of accrued and unpaid interest), the Repur-
         chase Payment Date and the Repurchase Put Date (as
         defined below);

                                       55

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

                     (iv) that, unless the Company defaults
         in depositing Cash with the Paying Agent in accordance with the last
         paragraph of this clause (b) or such payment is prevented pursuant to
         Article XII, any Debenture, or portion thereof, accepted for payment
         pursuant to the Repurchase Offer shall cease to accrue interest after
         the Repurchase Payment Date;

                       (v) that Holders electing to have a
         Debenture, or portion thereof, purchased pursuant to a Repurchase Offer
         will be required to surrender the Debenture, with the form entitled
         "Option of Holder to Elect Purchase" on the reverse of the Debenture
         completed, to the Paying Agent (which may not for purposes of this
         Section 11.1, notwithstanding anything in this Indenture to the
         contrary, be the Company or any Affiliate of the Company) at the
         address specified in the notice prior to the close of business on the
         earlier of (a) the third Business Day prior to the Repurchase Payment
         Date and (b) the third Business Day following the expiration of the
         Repurchase Offer (such earlier date being the "Repurchase Put Date");

                      (vi) that Holders will be entitled to
         withdraw their election, in whole or in part, if the Paying Agent
         (which may not for purposes of this Section 11.1, notwithstanding
         anything in this Indenture to the contrary, be the Company or any
         Affiliate of the Company) receives, up to the close of business on the
         Repurchase Put Date, a telegram, telex, facsimile transmission or
         letter setting forth the name of the Holder, the principal amount of
         the Debentures the Holder is withdrawing and a statement that such
         Holder is withdrawing his election to have such principal amount of
         Debentures purchased;

                      (vii) the Conversion Price as of the
         date of the notice and the date on which Debentures delivered for
         repurchase may no longer be converted as provided in Section 13.1 of
         this Indenture; and

                        (viii) a brief description of the
         events resulting in such Repurchase Event.


                                       56

                  Any such Repurchase Offer shall comply with all applicable
provisions of Federal and state laws, including those regulating tender offers,
if applicable, and any provisions of this Indenture which conflict with such
laws shall be deemed to be superseded by the provisions of such laws. The
Company shall publicly announce the results of any such Repurchase Offer on or
as soon as practicable after the Repurchase Payment date therefor.

                  On or before the Repurchase Payment Date, the Company shall
(i) accept for payment Debentures or portions thereof properly tendered pursuant
to the Repurchase Offer on or before the Repurchase Put Date, (ii) deposit with
the Paying Agent Cash sufficient to pay the Repurchase Payment (including
accrued and unpaid interest) for all Debentures or portions thereof so tendered
and (iii) deliver to the Trustee Debentures so accepted together with an
Officers' Certificate listing the Debentures or portions thereof being purchased
by the Company. The Paying Agent shall on the Repurchase Payment Date mail to
Holders of Debentures so accepted payment in an amount equal to the Repurchase
Payment for such Debentures, and the Trustee shall promptly authenticate and
mail or deliver to such Holders a new Debenture equal in principal amount to any
unpurchased portion of the Debenture surrendered. Any Debentures not so accepted
shall be promptly mailed or delivered by the Company to the Holder thereof.

                  SECTION 12.1.  DEBENTURES SUBORDINATED TO SENIOR
INDEBTEDNESS.

                  The Company and each Holder, by its acceptance of Debentures,
agree that (a) the payment of the principal of, premium, if any, and interest on
the Debentures and (b) any other payment in respect of the Debentures, including
on account of the acquisition or redemption of the Debentures by the Company
(including, without limitation, pursuant to Article XI) is subordinated, to the
extent and in the manner provided in this Article XII, to the prior payment in
full of all Senior Indebtedness of the Company, whether outstanding at the date
of this Indenture or thereafter created, incurred, assumed or guaranteed, and
that these subordination provisions are for the benefit of the holders of Senior
Indebtedness.

                                       57

                   This Article XII shall constitute a continuing offer to all
Persons who, in reliance upon such provisions, become holders of, or continue to
hold, Senior Indebtedness, and such provisions are made for the benefit of the
holders of Senior Indebtedness, and such holders are made obligees hereunder and
any one or more of them may enforce such provisions.

                  SECTION 12.2.  NO PAYMENT ON DEBENTURES IN CERTAIN
CIRCUMSTANCES.

                           (a)  No payment shall be made by the Company
on account of the principal of, premium, if any, or interest on the Debentures
or to acquire any of the Debentures (including any repurchases of Debentures at
the option of the Holder) for cash or property (other than Junior Securities of
the Company), or on account of the redemption provisions of the Debentures, in
the event of default in payment of any principal of, premium, if any, or
interest on any Senior Indebtedness of the Company when the same becomes due and
payable, whether at maturity or at a date fixed for prepayment or by declaration
or otherwise (a "Payment Default"), unless and until such Payment Default has
been cured or waived or otherwise has ceased to exist.

                           (b)  No payment (by set-off or otherwise) may
be made by or on behalf of the Company on account of the principal of, premium,
if any, or interest on, the Debentures or to acquire any of the Debentures
(including any repurchases of the Debentures at the option of the Holder) for
cash or property (other than Junior Securities), or on account of the redemption
provisions of the Debentures, in the event of any event of default (other than a
Payment Default) with respect to any Designated Senior Indebtedness permitting
the holders of such Designated Senior Indebtedness (or a trustee or other
representative on behalf of the holders thereof) to declare such Designated
Senior Indebtedness due and payable prior to the date on which it would
otherwise have become due and payable, upon written notice thereof to the
Company and the Trustee by any holders of Designated Senior Indebtedness (or a
trustee or other representative on behalf of the holders thereof) (the "Payment
Notice"), unless and until such event of default shall have been cured or waived
or otherwise has ceased to exist; PROVIDED, that such payments may not be
prevented pursuant to this Section 12.2(b) for more than 179 days after an
applicable Payment Notice has been received by the Trustee unless the Designated
Senior Indebtedness in respect

                                       58

of which such event of default exists has been declared due and payable in its
entirety, in which case no such payment may be made until such acceleration has
been rescinded or annulled or such Designated Senior Indebtedness has been paid
in full. No event of default that existed or was continuing on the date of any
Payment Notice (whether or not such event of default is on the same issue of
Designated Senior Indebtedness) may be made the basis for the giving of a second
Payment Notice, and only one such Payment Notice may be given in any 365-day
period.


                           (c)  In furtherance of the provisions of Sec-
tion 12.1, in the event that, notwithstanding the foregoing provisions of this
Section 12.2, any payment or distribution of assets of the Company (other than
Junior Securities of the Company) shall be received by the Trustee or the
Holders at a time when such payment or distribution was prohibited by the
provisions of this Section 12.2, then, unless such payment or distribution is no
longer prohibited by this Section 12.2, such payment or distribution (subject to
the provisions of Section 12.7) shall be received and held in trust by the
Trustee or such Holder or Paying Agent for the benefit of the holders of Senior
Indebtedness of the Company, and shall be paid or delivered by the Trustee or
such Holders or such Paying Agent, as the case may be, to the holders of Senior
Indebtedness of the Company remaining unpaid or unprovided for or their
representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing such Senior Indebtedness
of the Company may have been issued, ratably, according to the aggregate amounts
remaining unpaid on account of such Senior Indebtedness of the Company held or
represented by each, for application to the payment of all Senior Indebtedness
in full after giving effect to all concurrent payments and distributions to or
for the holders of such Senior Indebtedness.

                  SECTION 12.3.  DEBENTURES SUBORDINATED TO PRIOR
PAYMENT OF ALL SENIOR INDEBTEDNESS ON DISSOLUTION, LIQUI-
DATION OR REORGANIZATION.

                  Upon any distribution of assets of the Company or upon any
dissolution, winding up, total or partial liquidation or reorganization of the
Company, whether voluntary or involuntary, in bankruptcy, insolvency,
receivership or similar proceeding or upon assignment for the benefit of
creditors:

                                       59

                           (a)  the holders of all Senior Indebtedness
of the Company shall first be entitled to receive payments in full before the
Holders are entitled to receive any payment on account of the principal of,
premium, if any, and interest on the Debentures (other than Junior Securities of
the Company);

                           (b)  any payment or distribution of assets of
the Company of any kind or character, whether in cash, property or securities
(other than Junior Securities of the Company), to which the Holders or the
Trustee on behalf of the Holders would be entitled, except for the provisions of
this Article XII, shall be paid by the liquidating trustee or agent or other
Person making such a payment or distribution directly to the holders of such
Senior Indebtedness or their representative, ratably according to the respective
amounts of Senior Indebtedness held or represented by each, to the extent
necessary to make payment in full of all such Senior Indebtedness remaining
unpaid after giving effect to all concurrent payments and distributions to the
holders of such Senior Indebtedness; and

                           (c)  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 Junior Securities
of the Company), shall be received by the Trustee or the Holders or any Paying
Agent (or, if the Company or any Affiliate of the Company is acting as its own
Paying Agent, money for any such payment or distribution shall be segregated or
held in trust) on account of the principal of or interest on the Debentures
before all Senior Indebtedness of the Company is paid in full, such payment or
distribution (subject to the provisions of Section 12.7) shall be received and
held in trust by the Trustee or such Holder or Paying Agent for the benefit of
the holders of such Senior Indebtedness, or their respective representatives,
ratably according to the respective amounts of such Senior Indebtedness held or
represented by each, to the extent necessary to make payment as provided herein
of all such Senior Indebtedness remaining unpaid after giving effect to all
concurrent payments and distributions and all provisions therefor to or for the
holders of such Senior Indebtedness, but only to the extent that as to any
holder of such Senior Indebtedness, as promptly as practical following notice
from the Trustee to the holders of such Senior Indebtedness that such prohibited
payment has been received by the Trustee, Holder(s) or Paying Agent (or has been
segregated as provided above), such holder (or a

                                       60

representative therefor) notifies the Trustee of the amounts then due and owing
on such Senior Indebtedness, if any, held by such holder and only the amounts
specified in such notices to the Trustee shall be paid to the holders of such
Senior Indebtedness.

                  SECTION 12.4.  SECURITYHOLDERS TO BE SUBROGATED TO
RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS.

                  Subject to the payment in full of all Senior Indebtedness of
the Company as provided herein, the Holders of Debentures shall be subrogated to
the rights of the holders of such Senior Indebtedness to receive payments or
distributions of assets of the Company applicable to the Senior Indebtedness
until all amounts owing on the Debentures shall be paid in full, and for the
purpose of such subrogation no such payments or distributions to the holders of
such Senior Indebtedness by the Company, or by or on behalf of the Holders by
virtue of this Article XII, which otherwise would have been made to the Holders
shall, as between the Company and the Holders, be deemed to be payment by the
Company or on account of such Senior Indebtedness, it being understood that the
provisions of this Article XII are and are intended solely for the purpose of
defining the relative rights of the Holders, on the one hand, and the holders of
such Senior Indebtedness, on the other hand.

                  If any payment or distribution to which the Holders would
otherwise have been entitled but for the provisions of this Article XII shall
have been applied, pursuant to the provisions of this Article XII, to the
payment of amounts payable under Senior Indebtedness of the Company, then the
Holders shall be entitled to receive from the holders of such Senior
Indebtedness any payments or distributions received by such holders of Senior
Indebtedness in excess of the amount sufficient to pay all amounts payable under
or in respect of such Senior Indebtedness in full.

                  SECTION 12.5.  OBLIGATIONS OF THE COMPANY UNCONDI-
TIONAL.

                  Nothing contained in this Article XII or elsewhere in this
Indenture or in the Debentures is intended to or shall impair, as between the
Company and the Holders, the obligation of the Company, which is absolute and
unconditional, to pay to the Holders the principal of, premium, if any, and
interest on the Debentures as and when the same shall become due and payable in
accordance with their terms,

                                       61

or is intended to or shall affect the relative rights of the Holders and
creditors of the Company other than the holders of the Senior Indebtedness, nor
shall anything herein or therein prevent the Trustee or any Holder from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture, subject to the rights, if any, under this Article XII, of the
holders of Senior Indebtedness in respect of cash, property or securities of the
Company received upon the exercise of any such remedy. Notwithstanding anything
to the contrary in this Article XII or elsewhere in this Indenture or in the
Debentures, upon any distribution of assets of the Company referred to in this
Article XII, the Trustee, subject to the provisions of Sections 7.1 and 7.2, and
the Holders shall be entitled to rely upon any order or decree made by any court
of competent jurisdiction in which such dissolution, winding up, liquidation or
reorganization proceedings are pending, or a certificate of the liquidating
trustee or agent or other Person making any distribution to the Trustee or to
the Holders for the purpose of ascertaining the Persons entitled to participate
in such distribution, the holders of the Senior Indebtedness and other
Indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article XII so long as such court has been apprised of the provisions
of, or the order, decree or certificate makes reference to, the provisions of
this Article XII.

                  SECTION 12.6.  TRUSTEE ENTITLED TO ASSUME PAYMENTS
NOT PROHIBITED IN ABSENCE OF NOTICE.

                  The Trustee shall not at any time be charged with knowledge of
the existence of any facts which would prohibit the making of any payment to or
by the Trustee unless and until a Trust Officer of the Trustee or any Paying
Agent shall have received, no later than two Business Days prior to such
payment, written notice thereof from the Company or from one or more holders of
Senior Indebtedness or from any representative therefor and, prior to the
receipt of any such written notice, the Trustee, subject to the provisions of
Sections 7.1 and 7.2, shall be entitled in all respects conclusively to assume
that no such fact exists.

                                       62

                  SECTION 12.7.  APPLICATION BY TRUSTEE OF ASSETS
DEPOSITED WITH IT.

                  Amounts deposited in trust with the Trustee pursuant to and in
accordance with Article VIII shall be for the sole benefit of Securityholders
and, to the extent allocated for the payment of Debentures, shall not be subject
to the subordination provisions of this Article XII. Otherwise, any deposit of
assets with the Trustee or the Paying Agent (whether or not in trust) for the
payment of principal of or interest on any Debentures shall be subject to the
provisions of Sections 12.1, 12.2, 12.3 and 12.4; PROVIDED, THAT, if prior to
two Business Days preceding the date on which by the terms of this Indenture any
such assets may become distributable for any purpose (including without
limitation, the payment of either principal of or interest on any Debenture) the
Trustee or such Paying Agent shall not have received with respect to such assets
the written notice provided for in Section 12.6, then the Trustee or such Paying
Agent shall have full power and authority to receive such assets 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 date.

                  SECTION 12.8.  SUBORDINATION RIGHTS NOT IMPAIRED
BY ACTS OR OMISSIONS OF THE COMPANY OR HOLDERS OF SENIOR
INDEBTEDNESS.

                  No right of any present or future holders of any Senior
Indebtedness to enforce subordination provisions contained in this Article XII
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 of
this Indenture, regardless of any knowledge thereof which any such holder may
have or be otherwise charged with. The holders of Senior Indebtedness may
extend, renew, modify or amend the terms of the Senior Indebtedness or any
security therefor and release, sell or exchange such security and otherwise deal
freely with the Company, all without affecting the liabilities and obligations
of the parties to this Indenture or the Holders.

                                       63

                  SECTION 12.9.  SECURITYHOLDERS AUTHORIZE TRUSTEE
TO EFFECTUATE SUBORDINATION OF DEBENTURES.

                  Each Holder of the Debentures by his acceptance thereof
authorizes and expressly directs the Trustee on his behalf to take such action
as may be necessary or appropriate to effectuate the subordination provisions
contained in this Article XII and to protect the rights of the Holders pursuant
to this Indenture, and appoints the Trustee his attorney-in-fact for such
purpose, including, in the event of 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 of the Company),
the filing of a claim for the unpaid balance of his Debentures in the form
required in said proceedings and cause said claim to be approved. If the Trustee
does not file a proper claim or proof of debt in the form required in such
proceeding prior to 30 days before the expiration of the time to file such claim
or claims, then the holders of the Senior Indebtedness or their representative
are or is hereby authorized to have the right to file and are or is hereby
authorized to file an appropriate claim for and on behalf of the Holders of said
Debentures. Nothing herein contained shall be deemed to authorize the Trustee or
the holders of Senior Indebtedness or their representative to authorize or
consent to or accept or adopt on behalf of any Securityholder any plan of
reorganization, arrangement, adjustment or composition affecting the Debentures
or the rights of any Holder thereof, or to authorize the Trustee or the holders
of Senior Indebtedness or their representative to vote in respect of the claim
of any Securityholder in any such proceeding.

                  SECTION 12.10.  RIGHT OF TRUSTEE TO HOLD SENIOR
INDEBTEDNESS.

                  The Trustee shall be entitled to all of the rights set forth
in this Article XII in respect of any Senior Indebtedness at any time held by it
to the same extent as any other holder of Senior Indebtedness, and nothing in
this Indenture shall be construed to deprive the Trustee of any of its rights as
such holder.

                  SECTION 12.11.  ARTICLE XII NOT TO PREVENT EVENTS
OF DEFAULT.

                  The failure to make a payment on account of prin-
cipal of, premium, if any, or interest on the Debentures by

                                       64

reason of any provision of this Article XII shall not be construed as preventing
the occurrence of a Default or an Event of Default under Section 6.1 or in any
way prevent the Holders from exercising any right hereunder other than the right
to receive payment on the Debentures.

                  SECTION 12.12.  NO FIDUCIARY DUTY OF TRUSTEE TO
HOLDERS OF SENIOR INDEBTEDNESS.

                  The Trustee shall not be deemed to owe any fiduciary duty to
the holders of Senior Indebtedness, and shall not be liable to any such holders
(other than for its willful misconduct or negligence) if it shall in good faith
mistakenly pay over or distribute to the Holders of Debentures or the Company or
any other Person, cash, property or securities to which any holders of Senior
Indebtedness shall be entitled by virtue of this Article XII or otherwise.
Nothing in this Section 12.12 shall affect the obligation of any other such
Person to hold such payment for the benefit of, and to pay such payment over to,
the holders of Senior Indebtedness or their representative.

                                  ARTICLE XIII

                            CONVERSION OF DEBENTURES

                  SECTION 13.1.  CONVERSION PRIVILEGE.

                  Subject to and upon compliance with the provisions of this
Article XIII, at the option of the Holder thereof, any Debenture may at any time
be converted, in whole, or in part in multiples of $1,000 principal amount, into
fully paid and non-assessable shares of Common Stock issuable upon conversion of
the Debentures, at the conversion price in effect at the Date of Conversion (as
hereinafter defined), until and including, but not after, the close of business
on the date of Stated Maturity, PROVIDED that if such Debenture or some portion
thereof shall have been called for redemption or delivered for repurchase prior
to such date and no default is made in making due provision for the payment of
the redemption price in accordance with the terms of this Indenture, then, with
respect to such Debenture or portion thereof as has been so called or delivered,
such Debenture or portion thereof may be so converted until and including, but
not after, the close of business on the fifth Business Day prior to the
Redemption Date or the second Business Day prior to the Repurchase Payment Date,
as applicable, for such Debenture.

                                       65

                  SECTION 13.2.  EXERCISE OF CONVERSION PRIVILEGE.

                  In order to exercise the conversion privilege, the Holder of
any Debenture to be converted shall surrender such Debenture to the Company at
any time during usual business hours at its office or agency maintained for the
purpose as provided in this Indenture, accompanied by a fully executed written
notice, in substantially the form set forth on the reverse of the Debenture,
that the Holder elects to convert such Debenture or a stated portion thereof
constituting a multiple of $1,000 principal amount, and, if such Debenture is
surrendered for conversion during the period between the close of business on
any Record Date and the opening of business on the next following Interest
Payment Date and has not been called for redemption on a Redemption Date which
occurs within such period, accompanied also by payment of an amount equal to the
interest payable on such Interest Payment Date on the principal amount of the
Debenture being surrendered for conversion, notwithstanding such conversion.
Such notice of conversion shall also state the name or names (with address) in
which the certificate or certificates for shares of Common Stock shall be
issued. Debentures surrendered for conversion shall (if required by the Company
or the Trustee) be duly endorsed by, or be accompanied by a written instrument
or instruments of transfer in form satisfactory to the Company duly executed by,
the Holder or his attorney duly authorized in writing. As promptly as
practicable after the receipt of such notice and the surrender of such Debenture
as aforesaid, the Company shall, subject to the provisions of Section 13.8
hereof, issue and deliver at such office or agency to such Holder, or on his
written order, a certificate or certificates for the number of full shares of
Common Stock issuable on such conversion of Debentures in accordance with the
provisions of this Article XIII and Cash, as provided in Section 13.3 hereof, in
respect of any fraction of a share of Common Stock otherwise issuable upon such
conversion. Such conversion shall be deemed to have been effected immediately
prior to the close of business on the date (herein called the "Date of
Conversion") on which such Debenture shall have been surrendered as aforesaid,
and the Person or Persons in whose name or names any certificate or certificates
for shares of Common Stock shall be issuable upon such conversion shall be
deemed to have become on the Date of Conversion the holder or holders of record
of the shares represented thereby; PROVIDED, HOWEVER, that any such surrender on
any date when the stock transfer books of the Company shall be closed shall
cause the Person or Persons in whose name or names the

                                       66

certificate or certificates for such shares are to be issued to be deemed to
have become the recordholder or holders thereof for all purposes at the opening
of business on the next succeeding day on which such stock transfer books are
open but such conversion shall nevertheless be at the conversion price in effect
at the close of business on the date when such Debenture shall have been so
surrendered with the conversion notice. In the case of conversion of a portion,
but less than all, of a Debenture, the Company shall as promptly as practicable
execute, and the Trustee shall authenticate and deliver to the Holder thereof,
at the expense of the Company, a Debenture or Debentures in the aggregate
principal amount of the unconverted portion of the Debenture surrendered. Except
as otherwise expressly provided in this Indenture, no payment or adjustment
shall be made for interest accrued on any Debenture (or portion thereof)
converted or for dividends or distributions on any Common Stock issued upon
conversion of any Debenture.

                  SECTION 13.3.  FRACTIONAL INTERESTS.

                  No fractions of shares or scrip representing fractions of
shares shall be issued upon conversion of Debentures. If more than one Debenture
shall be surrendered for conversion at one time by the same holder, the number
of full shares which shall be issuable upon conversion thereof shall be computed
on the basis of the aggregate principal amount of the Debentures so surrendered.
If any fraction of a share of Common Stock would, except for the foregoing
provisions of this Section 13.3, be issuable on the conversion of any Debenture
or Debentures, the Company shall make payment in lieu thereof in an amount of
Cash equal to the value of such fraction computed on the basis of the last sale
price of the Common Stock as reported on the NASDAQ National Market System (or
if not admitted to trading thereon, then on the principal national securities
exchange on which the Common Stock is listed or admitted to trading) on the last
Trading Day prior to the Date of Conversion or if no such sale takes place on
such day, the last sale price for such day shall be the average of the closing
bid and asked prices regular way on the NASDAQ National Market System (or if not
admitted to trading thereon, on the principal national securities exchange on
which the Common Stock is listed or admitted to trading) for such day (any such
last sale price being hereinafter referred to as the "Last Sale Price"). If on
such Trading Day the Common Stock is not quoted by any such organization, the
fair value of such Common Stock on such day, as reasonably determined in good

                                       67

faith by the Board of Directors of the Company, shall be
used.

                  SECTION 13.4.  CONVERSION PRICE.

                  The conversion price per share of Common Stock issuable upon
conversion of the Debentures shall initially be $12.25.

                  SECTION 13.5.  ADJUSTMENT OF CONVERSION PRICE.

                  The conversion price (herein called the "Conversion Price")
shall be subject to adjustment from time to time as follows:

                           (a)  In case the Company shall (l) make or
pay a dividend or make a distribution in shares of Common Stock on any class of
Capital Stock of the Company, (2) subdivide its outstanding shares of Common
Stock into a greater number of shares or (3) combine or reclassify its
outstanding shares of Common Stock into a smaller number of shares, the
Conversion Price in effect immediately prior to such action shall be adjusted so
that the holder of any Debenture 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 Debenture been converted
immediately prior thereto. An adjustment made pursuant to this subsection (a)
shall become effective immediately, except as provided in subsection (h) below,
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,
options or warrants to all holders of Common Stock entitling them to subscribe
for or purchase shares of Common Stock at a price per share less than the then
current market price per share of the Common Stock (as determined pursuant to
subsection (f) below) on the record date mentioned below, the Conversion Price
shall be adjusted to a price so that the same shall equal the price determined
by multiplying:

                       (i) the Conversion Price in effect
         immediately prior to the record date by a fraction, of
         which

                                       68

                       (ii) the numerator shall be (A) the
         number of shares of Common Stock outstanding on the record date plus
         (B) the number of shares which the aggregate offering price of the
         total number of shares so offered for subscription or purchase would
         purchase at such current market price (determined by multiplying such
         total number of shares by the exercise price of such rights, options or
         warrants and dividing the product so obtained by such current market
         price), and of which

                     (iii) the denominator shall be (A) the
         number of shares of Common Stock outstanding on the record date plus
         (B) the number of additional shares of Common Stock which are so
         offered for subscription or purchase.

                  Such adjustment shall become effective immediately, except as
provided in subsection (h) below, after the record date for the determination of
holders entitled to receive such rights, options or warrants.

                           (c)  In case the Company or any Subsidiary of
the Company shall distribute to all holders of Common Stock, any of its assets,
evidences of indebtedness, cash or securities other than Common Stock (other
than (x) dividends or distributions exclusively in cash or (y) any dividend or
distribution for which an adjustment is required to be made in accordance with
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 record date of such
distribution by a fraction of which the numerator shall be the then current
market price per share of the Common Stock (determined as provided in subsection
(f) below) on the record date mentioned below less the then fair market value
(as reasonably determined in good faith by the Board of Directors of the
Company) of the portion of the assets, evidences of indebtedness, cash or
securities so distributed applicable to one share of Common Stock, and of which
the denominator shall be such current market price per share of the Common
Stock. Such adjustment shall become effective immediately, except as provided in
subsection (h) below, after the record date for the determination of
stockholders entitled to receive such distribution.

                           (d)  In case the Company or any Subsidiary of
the Company shall make any distribution consisting exclu-

                                       69

sively of cash (excluding any cash portion of distributions for which an
adjustment is required to be made in accordance with (c) above, or cash
distributed upon a merger or consolidation to which Section 13.6 applies) to all
holders of Common Stock in an aggregate amount that, combined together with (i)
all other such all-cash distributions made within the then preceding 12 months
in respect of which no adjustment has been made and (ii) any cash and the fair
market value of other consideration paid or payable in respect of any tender
offer by the Company or any of its Subsidiaries for Common Stock (any such
tender offer being referred to as an "Offer") concluded within the preceding 12
months in respect of which no adjustment has been made, exceeds 12.5% of the
Company's market capitalization (defined as being the product of the then
current market price of the Common Stock (determined as provided in subsection
(f) below) times the number of shares of Common Stock then outstanding) on the
record date of such distribution, 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 record date of such
distribution by a fraction of which the numerator shall be the then current
market price per share of the Common Stock on such record date less the amount
of the cash and the fair market value (as reasonably determined in good faith by
the Board of Directors of the Company) of the other consideration so distributed
within such preceding 12 months applicable to one share of Common Stock, and of
which the denominator shall be such current market price per share of the Common
Stock. Such adjustment shall become effective immediately, except as provided in
subsection (h) below, after the record date for the determination of
stockholders entitled to receive such distribution.

                           (e)  In case the Company or any Subsidiary of
the Company shall complete an Offer that involves an aggregate consideration
having a fair market value as of the expiration of such Offer (the "Expiration
Time") that, together with (i) any cash and other consideration paid or payable
in an Offer that expired within the 12 months preceding the expiration of such
Offer in respect of which no adjustment has been made and (ii) the aggregate
amount of all other all-cash distributions made within the 12 months preceding
the expiration of such Offer in respect of which no adjustment has been made
(other than all-cash distributions made upon a merger or consolidation to which
Section 13.6 applies), exceeds 12.5% of the Company's market capitalization
(defined as being the product of the then

                                       70

current market price of the Common Stock (determined as provided in subsection
(f) below) times the number of shares of Common Stock outstanding (including any
tendered shares) on the Expiration Time), the Conversion Price shall be reduced
by multiplying such Conversion Price in effect immediately prior to the
Expiration Time by a fraction of which the numerator shall be (i) the product of
the then current market price per share (determined as provided in subsection
(f) below) of the Common Stock on the Expiration Time times the number of shares
of Common Stock outstanding (including any tendered shares) on the Expiration
Time minus (ii) the fair market value (as reasonably determined in good faith by
the Board of Directors of the Company) of the aggregate consideration payable to
stockholders based on the acceptance (up to any maximum specified in the terms
of the Offer) of all shares validly tendered and not withdrawn as of the
Expiration Time (the shares deemed so accepted being referred to as the
"Purchased Shares") and the denominator shall be the product of (i) such current
market price per share on the Expiration Time times (ii) such number of
outstanding shares on the Expiration Time less the number of Purchased Shares,
such reduction to become effective immediately prior to the opening of business
on the day following the Expiration Time.

                           (f)  For the purpose of any computation under
subsections (b), (c), (d) and (e) above, the current market price per share of
Common Stock on any date shall be deemed to be the average of the Last Sale
Prices of a share of Common Stock for the five consecutive Trading Days selected
by the Company commencing not more than 20 Trading Days before, and ending not
later than, the earlier of the date in question and the date before the "`ex'
date", with respect to the issuance, distribution or Offer requiring such
computation. If on any such Trading Day the Common Stock is not quoted by any
organization referred to in the definition of Last Sale Price in Section 13.3
hereof, the fair value of the Common Stock on such day, as reasonably determined
in good faith by the Board of Directors of the Company, shall be used. For
purposes of this paragraph, the term "`ex' date," when used with respect to any
issuance, distribution or payments with respect to an Offer, means the first
date on which the Common Stock trades regular way on the NASDAQ National Market
System (or if not listed or admitted to trading thereon, then on the principal
national securities exchange on which the Common Stock is listed or admitted to
trading) without the right to receive such issuance, distribution or Offer.

                                       71

                           (g)  In addition the foregoing adjustments in
subsections (a), (b), (c), (d) and (e) above, the Company will be permitted to
make such reductions in the Conversion Price as it considers to be advisable in
order that any event treated for Federal income tax purposes as a dividend of
stock or stock rights will not be taxable to the holders of the shares of Common
Stock.

                           (h)  In any case in which this Section 13.5
shall require that an adjustment be made immediately following a record date,
the Company may elect to defer the effectiveness of such adjustment (but in no
event until a date later than the effective time of the event giving rise to
such adjustment), in which case the Company shall, with respect to any Debenture
converted after such record date and on and before such adjustment shall have
become effective (i) defer paying any Cash payment pursuant to Section 13.3
hereof or issuing to the Holder of such Debenture the number of shares of Common
Stock and other capital stock of the Company (or other assets or securities)
issuable upon such conversion in excess of the number of shares of Common Stock
and other Capital Stock of the Company issuable thereupon only on the basis of
the Conversion Price prior to adjustment, and (ii) not later than five Business
Days after such adjustment shall have become effective, pay to such Holder the
appropriate Cash payment pursuant to Section 13.3 hereof and issue to such
Holder the additional shares of Common Stock and other Capital Stock of the
Company issuable on such conversion.

                           (i)  No adjustment in the Conversion Price
shall be required unless such adjustment would require an increase or decrease
of at least 1.0% of the Conversion Price; PROVIDED that the Company may make any
such adjustment at its election and PROVIDED FURTHER that any adjustments which
by reason of this subsection (i) are not required to be made shall be carried
forward and taken into account in any subsequent adjustment. All calculations
under this Article XIII shall be made to the nearest cent or to the nearest
one-hundredth of a share, as the case may be.

                           (j)  Whenever the Conversion Price is adjust-
ed as herein provided, the Company shall promptly (i) file with the Trustee and
each conversion agent an Officers' Certificate setting forth the Conversion
Price after such adjustment and setting forth a brief statement of the facts
requiring such adjustment, which certificate shall be conclusive evidence of the
correctness of such adjustment, and

                                       72

(ii) mail or cause to be mailed a notice of such adjustment to each Holder of
Debentures at his address as the same appears on the registry books of the
Company.

                  SECTION 13.6.  CONTINUATION OF CONVERSION PRIVI-
LEGE IN CASE OF RECLASSIFICATION, CHANGE, MERGER, CONSOLIDA-
TION OR SALE OF ASSETS.

                  If any of the following shall occur, namely: (a) any
reclassification or change of outstanding shares of Common Stock issuable upon
conversion of the Debentures (other than a change in par value, or from par
value to no par value, or from no par value to par value, or as a result of a
subdivision or combination), (b) any consolidation or merger of the Company with
or into any other Person, or the merger of any other Person with or into the
Company (other than a merger which does not result in any reclassification,
change, conversion, exchange or cancellation of outstanding shares of Common
Stock) or (c) sale, transfer or conveyance of all or substantially all of the
assets of the Company (computed on a consolidated basis), then the Company, or
such successor or purchasing entity, 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
providing that the Holder of each Debenture then outstanding shall have the
right to convert such Debenture only into the kind and amount of shares of stock
and other securities and property (including cash) receivable upon such
reclassification, change, consolidation, merger, sale, transfer or conveyance by
a holder of the number of shares of Common Stock issuable upon conversion of
such Debenture immediately prior to such reclassification, change,
consolidation, merger, sale, transfer or conveyance assuming such holder of
Common Stock of the Company (i) is not a person party to such transaction and
(ii) failed to exercise his rights of an election, if any, as to the kind or
amount of securities, cash and other property receivable upon such
reclassification, change, consolidation, merger, sale, transfer or conveyance
(PROVIDED that if the kind or amount of securities, cash, and other property
receivable upon such reclassification, change, consolidation, merger, sale,
transfer or conveyance is not the same for each share of Common Stock of the
Company held immediately prior to such reclassification, change, consolidation,
merger, sale, transfer or conveyance in respect of which such rights of election
shall not have been exercised ("non-electing share"), then for the purpose of
this Section 13.6 the kind and amount of securities, cash

                                       73

and other property receivable upon such reclassification, change, consolidation,
merger, sale, transfer or conveyance by each non-electing share shall be deemed
to be the kind and amount so receivable per share by a plurality of the
non-electing shares). Such supplemental indenture shall provide for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Article XIII. 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 shares of Common Stock
includes shares of stock or other securities and property (including cash) 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
Debentures as the Board of Directors of the Company shall reasonably consider
necessary by reason of the foregoing. The provisions of this Section 13.6 shall
similarly apply to successive consolidations, mergers, sales or conveyances.

                  Notice of the execution of each such supplemental indenture
shall be mailed to each Holder of Debentures at his address as the same appears
on the registry books of the Company.

                  Neither the Trustee nor any conversion agent shall be under
any responsibility to determine the correctness of any provisions contained in
any such supplemental indenture relating either to the kind or amount of shares
of stock or securities or property (including cash) receivable by Holders of
Debentures upon the conversion of their Debentures after any such
reclassification, change, consolidation, merger, sale or conveyance or to any
adjustment to be made with respect thereto, but, subject to the provisions of
Article VII hereof, may accept as conclusive evidence of the correctness of any
such provisions, and shall be protected in relying upon, the Officers'
Certificate (which the Company shall be obligated to file with the Trustee prior
to the execution of any such supplemental indenture) with respect thereto.

                                       74

                  SECTION 13.7.  NOTICE OF CERTAIN EVENTS.

                  In case:

                  (a) the Company shall declare a dividend (or any other
distribution) payable to the holders of Common Stock (other than cash dividends
or dividends payable in Common Stock); or

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

                  (c) the Company shall authorize any reclassification or change
of the Common Stock (excluding a subdivision or combination of its outstanding
shares of Common Stock, or a change in par value, or from par value to no par
value, or from no par value to par value), or any consolidation or merger to
which the Company is a party and for which approval of any stockholders of the
Company is required, or the sale or conveyance of all or substantially all the
property or business of the Company; or

                  (d) there shall be proposed any voluntary or
involuntary dissolution, liquidation or winding-up of the
Company; or

                  (e)  the Company or any of its Subsidiaries shall
complete an Offer;

then, the Company shall cause to be filed at the office or agency maintained for
the purpose of conversion of the Debentures as provided in Section 4.2 hereof,
and shall cause to be mailed to each Holder of Debentures, at his address as it
shall appear on the registry books of the Company, at least 20 days before the
date hereinafter specified (or the earlier of the dates hereinafter specified,
in the event that more than one date is specified), a notice stating the date on
which (1) a record is expected to be taken for the purpose of such dividend,
distribution, rights, warrants, options or convertible or exchangeable
securities or Offer, or if a record is not to be taken, the date as of which the
holders of Common Stock of record to be entitled to such dividend, distribution,
rights, warrants, options or convertible or exchangeable securities or to
participate in such Offer are to be determined, or (2) such

                                       75

reclassification, change, consolidation, merger, sale, conveyance, dissolution,
liquidation or winding-up is expected to become effective and the date, if any
is to be fixed, as of which it is expected that holders of Common Stock of
record shall be entitled to exchange their shares of Common Stock for securities
or other property deliverable upon such reclassification, change, consolidation,
merger, sale, conveyance, dissolution, liquidation or winding-up.

                  SECTION 13.8.  TAXES ON CONVERSION.

                  The Company will pay any and all documentary, stamp or similar
taxes payable to the United States of America or any political subdivision or
taxing authority thereof or therein in respect of the issue or delivery of
shares of Common Stock on conversion of Debentures pursuant thereto; PROVIDED,
HOWEVER, that the Company shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issue or delivery of shares
of Common Stock in a name other than that of the Holder of the Debentures to be
converted and no such issue or delivery shall be made unless and until the
Person requesting such issue or delivery has paid to the Company the amount of
any such tax or has established, to the satisfaction of the Company, that such
tax has been paid. The Company extends no protection with respect to any other
taxes imposed in connection with conversion of Debentures.

                  SECTION 13.9.  COMPANY TO PROVIDE STOCK.

                  The Company shall reserve, free from preemptive rights, out of
its authorized but unissued shares, sufficient shares to provide for the
conversion of the Debentures from time to time as such Debentures are presented
for conversion, PROVIDED, that nothing contained herein shall be construed to
preclude the Company from satisfying its obligations in respect of the
conversion of Debentures by delivery of repurchased shares of Common Stock which
are held in the treasury of the Company.

                  If any shares of Common Stock to be reserved for the purpose
of conversion of Debentures hereunder require registration with or approval of
any governmental authority under any Federal or state law before such shares may
be validly issued or delivered upon conversion, then the Company covenants that
it will in good faith and as expeditiously as possible endeavor to secure such
registration or approval, as the case may be, PROVIDED, HOWEVER, that nothing in

                                       76

this Section 13.9 shall be deemed to limit in any way the obligations of the
Company provided in this Article XIII.

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

                  The Company covenants that all shares of Common Stock which
may be issued upon conversion of Debentures will upon issue be fully paid and
non-assessable by the Company and free of preemptive rights.

                  SECTION 13.10.  DISCLAIMER OF RESPONSIBILITY FOR
CERTAIN MATTERS.

                  Neither the Trustee nor any agent of the Trustee shall at any
time be under any duty or responsibility to any Holder of Debentures to
determine whether any facts exist which may require any adjustment of the
Conversion Price, or with respect to the Officers' Certificate referred to in
Section 13.5 hereof, or with respect to the nature or extent of any such
adjustment when made, or with respect to the method employed, or herein or in
any supplemental indenture provided to be employed, in making the same. Neither
the Trustee nor any agent of the Trustee shall be accountable with respect to
the validity or value (or the kind or amount) of any shares of Common Stock, or
of any securities or property (including cash), which may at any time be issued
or delivered upon the conversion of any Debenture; and neither the Trustee nor
any conversion agent makes any representation with respect thereto. Neither the
Trustee nor any agent of the Trustee shall be responsible for any failure of the
Company to issue, register the transfer of or deliver any shares of Common Stock
or stock certificates or other securities or property (including cash) upon the
surrender of any Debenture for the purpose of conversion or, subject to Article
VII hereof, to comply with any of the covenants of the Company contained in this
Article XIII.

                  SECTION 13.11.  RETURN OF FUNDS DEPOSITED FOR
REDEMPTION OF CONVERTED DEBENTURES.

                  Any funds which at any time shall have been deposited by the
Company or on its behalf with the Trustee or any

                                       77

other Paying Agent for the purpose of paying the principal of and interest on
any of the Debentures and which shall not be required for such purposes because
of the conversion of such Debentures, as provided in this Article XIII, shall
after such conversion be repaid to the Company by the Trustee or such other
Paying Agent.

                  SECTION 13.12.  CERTAIN DISTRIBUTIONS.

                  In the event that the Company distributes rights, options or
warrants (other than those referred to in Section 13.5(b) hereof) pro rata to
holders of Common Stock, so long as any such rights, options or warrants have
not expired or been redeemed by the Company, the Holder of any Debenture
surrendered for conversion will 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, options or warrants to be determined
as follows: (i) if such conversion occurs on or prior to the date for the
distribution to the holders of rights, options or warrants of separate
certificates evidencing such rights, options or warrants (the "Distribution
Date"), the same number of rights, options or warrants 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, options or warrants, and (ii) if
such conversion occurs after such Distribution Date, the same number of rights,
options or warrants to which a holder of the number of shares of Common Stock
into which such Debenture was convertible immediately prior to such Distribution
Date would have been entitled on such Distribution Date in accordance with the
terms and provisions of and applicable to the rights, options or warrants. The
conversion price of the Debentures will not be subject to adjustment on account
of any declaration, distribution or exercise of such rights, options or
warrants.

                                   ARTICLE XIV

                                  MISCELLANEOUS

                  SECTION 14.1.  TIA CONTROLS.

                  If any provision of this Indenture limits, qualifies, or
conflicts with the duties imposed by operation of

                                       78

the TIA, the imposed duties, upon qualification of this Indenture under the TIA,
shall control.

                  SECTION 14.2.  NOTICES.

                  Any notices or other communications to the Company or the
Trustee required or permitted hereunder shall be in writing, and shall be

with the approval of the Trustee shall constitute a sufficient mailing of such
notice.

                  SECTION 14.3.  COMMUNICATIONS BY HOLDERS WITH

substance reasonably satisfactory to the Trustee) stating that, in the opinion
of such counsel, all such conditions precedent have been complied with.

                  SECTION 14.5.  STATEMENTS REQUIRED IN CERTIFI-
CATE OR OPINION.

                  Each certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture shall include:

                                       80

                           (1)  a statement that the Person making
such certificate or opinion has read such covenant or

the opinion of each such Person, such condition or covenant has been complied
with; PROVIDED, HOWEVER, that with respect to matters of fact an Opinion of
Counsel may rely on an Officers' Certificate or certificates of public
officials.

                  SECTION 14.6.  RULES BY TRUSTEE, PAYING AGENT,
REGISTRAR.

                  The Trustee may make reasonable rules for action by or at a
meeting of Securityholders. The Paying Agent or Registrar may make reasonable
rules for its functions.

                  SECTION 14.7.  LEGAL HOLIDAYS.

                  A "Legal Holiday" is a Saturday, a Sunday or a day on which
banking institutions in New York, New York are authorized or obligated by law or
executive order to close. If a payment date is a Legal Holiday at such place,

within-mentioned Indenture.

                                                            MARINE MIDLAND BANK,

                    6 1/4% CONVERTIBLE SUBORDINATED DEBENTURE
                                    DUE 2006


1.       INTEREST.

                  Pride Petroleum Services, Inc., a Louisiana corporation
(hereinafter called the "Company," which term includes any successors under the
Indenture hereinafter referred to), promises to pay interest on the principal
amount of this Debenture at the rate of 6.25% per annum. To the extent it is
lawful, the Company promises to pay interest on any interest payment due but
unpaid on such principal amount at a rate of 6.25% per annum compounded
semi-annually.

                  The Company will pay interest semi-annually on February 15 and
August 15 of each year (each, an "Interest Payment Date"), commencing August 15,
1996. Interest on the Debentures will accrue from the most recent date to which
interest has been paid or, if no interest has been paid on the Debentures, from
January 26, 1996. Interest will be computed on the basis of a 360-day year
consisting of twelve 30-day months.

2.       METHOD OF PAYMENT.

                  The Company shall pay interest on the Debentures (except
defaulted interest) to the Persons who are the registered Holders at the close
of business on the Record Date (specified on the face hereof) immediately
preceding the Interest Payment Date. Holders must surrender Debentures to a
Paying Agent to collect principal payments. Any such interest not so punctually
paid, and defaulted interest relating thereto, may be paid to the Persons who
are registered Holders at the close of business on a Special Record Date for the
payment of such defaulted interest, as more fully provided in the Indenture
referred to below. Except as provided below, the Company shall pay principal and
interest in such coin or currency of the United States of America as at the time
of payment shall be legal tender for payment of public and private debts ("U.S.
Legal Tender"). However, the Company may pay principal and interest by wire
transfer of Federal funds or by its check payable in such U.S. Legal Tender. The
Company may deliver any such interest payment to the Paying Agent or the Company
may mail

                                      A-4

any such interest payment to a Holder at the Holder's regis-
tered address.

3.       PAYING AGENT AND REGISTRAR.

                  Initially, Marine Midland Bank (the "Trustee," which term
includes any successor trustee under the Indenture referred to below) will act
as Paying Agent and Registrar. The Company may change any Paying Agent,
Registrar or co-Registrar without notice to the Holders. The Company or any of
its Subsidiaries may, subject to certain exceptions, act as Paying Agent,
Registrar or coRegistrar.

4.       INDENTURE.

                  The Company issued the Debentures under an Indenture, dated as
of January 26, 1996 (the "Indenture"), between the Company and the Trustee.
Capitalized terms herein are used as defined in the Indenture unless otherwise
defined herein. The terms of the Debentures include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act, as in effect on the date of the Indenture, except as otherwise
provided thereby. The Debentures are subject to all such terms, and Holders of
Debentures are referred to the Indenture and said Act for a statement of them.
The Debentures are general unsecured obligations of the Company limited in
aggregate principal amount to $70,000,000 ($80,500,000 if the underwriters
exercise their over-allotment option in full).

5.       REDEMPTION.

                  The Debentures may be redeemed in whole or from time to time
in part at any time on and after March 1, 1999, at the option of the Company, at
the following Redemption Prices (expressed as percentages of the principal
amount) if redeemed during the 12-month period commencing February 15 of the
years indicated below, in each case together with any accrued but unpaid
interest thereon to the Redemption Date:


YEAR                                PERCENTAGE

1999 . . . . . . . . . . . . . . . . 103.125 %
2000 . . . . . . . . . . . . . . . . 102.083 %
2001 . . . . . . . . . . . . . . . . 101.042 %
2002 and thereafter. . . . . . . . . 100.000 %

                                      A-5

                  The Debentures will not be subject to any sinking fund. Any
such redemption will comply with Article III of the Indenture.

6.       NOTICE OF REDEMPTION.

                  Notice of redemption will be sent by first class mail, at
least 30 days and not more than 60 days prior to the Redemption Date to the
Holder of each Debenture to be redeemed at such Holder's last address as then
shown upon the registry books of the Registrar. Debentures may be redeemed in
part in multiples of $1,000 only.

                  Except as set forth in the Indenture, from and after any
Redemption Date, if monies for the redemption of the Debentures called for
redemption shall have been deposited with the Paying Agent on such Redemption
Date and payment of the Debentures called for redemption is not prohibited under
Article XII of the Indenture, the Debentures called for redemption will cease to
bear interest and the only right of the Holders of such Debentures will be to
receive payment of the Redemption Price, plus any accrued and unpaid interest to
the Redemption Date.

7.       DENOMINATIONS; TRANSFER; EXCHANGE.

                  The Debentures are in registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000. A Holder may register
the transfer of, or exchange Debentures in accordance with, the Indenture. The
Registrar may require a Holder, 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 register the transfer
of or exchange any Debentures selected for redemption.

8.       PERSONS DEEMED OWNERS.

                  The registered Holder of a Debenture may be treated as the
owner of it for all purposes.

9.       UNCLAIMED MONEY.

                  If money for the payment of principal or interest remains
unclaimed for two years, the Trustee and the Paying Agent(s) will pay the money
back to the Company at its writ-

                                      A-6

ten request. After that, all liability of the Trustee and such Paying Agent(s)
with respect to such money shall cease.

10.      AMENDMENT; SUPPLEMENT; WAIVER.

                  Subject to certain exceptions, the Indenture or the Debentures
may be amended or supplemented, and any existing Default or Event of Default or
compliance with any provision may be waived, with the written consent of the
Holders of a majority in aggregate principal amount of the Debentures then
outstanding. Without notice to or consent of any Holder, the parties thereto may
amend or supplement the Indenture or the Debentures to, among other things, cure
any ambiguity, defect or inconsistency, or make any other change that does not
adversely affect the rights of any Holder of a Debenture.

11.      CONVERSION RIGHTS.

                  Subject to the provisions of the Indenture, the Holders have
the right to convert the principal amount of the Debentures into fully paid and
nonassessable shares of Common Stock of the Company at the initial conversion
price per share of Common Stock of $12.25 (equivalent to a conversion rate of
81.633 shares per $1000 principal amount of Debentures), or at the adjusted
conversion price then in effect, if adjustment has been made as provided in the
Indenture, upon surrender of the Debenture to the Company, together with a fully
executed notice in substantially the form attached hereto and, if required by
the Indenture, an amount equal to accrued interest payable on such Debenture.

12.      RANKING.

                  Payment of principal, premium, if any, and interest on the
Debentures is subordinated, in the manner and to the extent set forth in the
Indenture, to the prior payment in full of all Senior Indebtedness.

13.      REPURCHASE AT OPTION OF HOLDER.

                  If there is a Repurchase Event, the Company shall be required
to offer to purchase on the Repurchase Payment Date all outstanding Debentures
at a purchase price equal to 100% of the principal amount thereof, plus accrued
and unpaid interest, if any, to the Repurchase Payment Date. Holders of
Debentures will receive a Repurchase Offer from the Company prior to any related
Repurchase Payment Date and

                                      A-7

may elect to have such Debentures purchased by completing the form entitled
"Option of Holder to Elect Purchase" appearing below.

14.      SUCCESSORS.

                  When a successor assumes all the obligations of its
predecessor under the Debentures and the Indenture, the predecessor will be
released from those obligations.

15.      DEFAULTS AND REMEDIES.

                  If an Event of Default occurs and is continuing (other than an
Event of Default relating to certain events of bankruptcy, insolvency or
reorganization), then in every such case, unless the principal of all of the
Debentures shall have already become due and payable, either the Trustee or the
Holders of 25% in aggregate principal amount of Debentures then outstanding may
declare all the Debentures to be due and payable immediately in the manner and
with the effect provided in the Indenture. Holders of Debentures may not enforce
the Indenture or the Debentures except as provided in the Indenture. The Trustee
may require indemnity satisfactory to it before it enforces the Indenture or the
Debentures. Subject to certain limitations, Holders of a majority in aggregate
principal amount of the Debentures then outstanding may direct the Trustee in
its exercise of any trust or power. The Trustee may withhold from Holders of
Debentures notice of any continuing Default or Event of Default (except a
Default in payment of principal or interest), if it determines that withholding
notice is in their interest.

16.  TRUSTEE DEALINGS WITH COMPANY.

                  The Trustee under the Indenture, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Company or its Affiliates, and may otherwise deal with the Company or
its Affiliates as if it were not the Trustee.

17.      NO RECOURSE AGAINST OTHERS.

                  No stockholder, director, officer or employee, as such, past,
present or future, of the Company or any successor corporation shall have any
personal liability in respect of the obligations of the Company under the
Debentures or the Indenture by reason of his or its status as such stock-

                                      A-8

holder, director, officer or employee. Each Holder of a Debenture by accepting a
Debenture waives and releases all such liability. The waiver and release are
part of the consideration for the issuance of the Debentures.

18.      AUTHENTICATION.

                  This Debenture shall not be valid until the Trustee or
authenticating agent signs the certificate of authentication on the other side
of this Debenture.

19.      ABBREVIATIONS AND DEFINED TERMS.

                  Customary abbreviations may be used in the name of a Holder of
a Debenture or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

20.      CUSIP NUMBERS.

                  Pursuant to a recommendation promulgated by the Committee on
Uniform Debenture Identification Procedures, the Company will cause CUSIP
