     C.     The Board of Directors of the Company has determined that an amendment

     Accordingly, the parties hereto agree that:

     1.     AMENDMENTS.

     (a)  Amendment to Definition of “Acquiring Person.” Section 1 (a) of the
Rights Agreement is hereby amended by adding the following new paragraph at the
end of Section 1(a):

     “Notwithstanding anything to the contrary in this Agreement, including
without limitation Sections 1(a), 1(l), 1(hh), 1(kk), 3, 7, 11(a)(ii) and
13(a), (i) neither Imperial Parking Management, LLC, IPK Acquisition
Corporation, nor any of their Affiliates shall be deemed to be an Acquiring
Person, (ii) no Stock Acquisition Date, no Distribution Date and no Triggering
Event shall be deemed to occur, (iii) the Rights will not separate from the
Common Stock, and (iv) the Rights shall not become exercisable, in each case as
a result of the execution, delivery or performance of the Merger Agreement (as
defined below) or the Voting Agreements (as defined below), or the public
announcement thereof, or the consummation of the Merger (as defined in such
Merger Agreement) or any other transactions contemplated by the Merger
Agreement, or the grant or exercise of any rights (including option rights)
under the Voting Agreements, or the consummation of any other transactions
contemplated by the Voting Agreements. For purposes of this Section 1(a),
“Merger Agreement” shall mean the Agreement and Plan of Merger dated as of
January 22, 2004 by and among the Company, Imperial Parking Management, LLC and
IPK Acquisition Corporation, and “Voting Agreements” shall mean the Voting
Agreement(s) and the Voting and Option Agreement dated as of January 22, 2004
among Imperial Parking Management, LLC and the stockholders listed on the
signature pages thereto.

     (b)  Amendment to Definition of “Expiration Date.” The first sentence of
Section 7(a) of the Rights Agreement is hereby amended by: (x) deleting “or”
immediately prior to “(iii) the time” and replacing it with a “,” and (y)
replacing “(the earlier of (i), (ii) or (iii) being herein

 

 

referred to as the “Expiration Date”) with “or (iv) immediately prior to
the “Effective Time” as defined in the Merger Agreement (the earlier of (i),
(ii), (iii) or (iv) being herein referred to as the “Expiration Date”)”.

     2.     CERTIFICATION. This Section 2 shall constitute an officer’s
certificate for purposes of Section 27 of the Rights Agreement, and the Company
and the officer of the Company signing this Amendment below, on behalf of the
Company, hereby (i) certify that to the best of their knowledge this Amendment
is in compliance with the terms of Section 27 of the Rights Agreement and (ii)
request and direct that the Rights Agent execute and deliver this Amendment, in
accordance with Section 27.

     3.     MISCELLANEOUS. Except as set forth herein, the Rights Agreement shall

construed in accordance with the laws of such State applicable to contracts to
be made and performed entirely within such State and without regard to
conflicts of laws and principles. This Amendment may be executed in any number
of counterparts, each of such counterparts shall for all purposes be deemed to
be an original, and all such counterparts shall together constitute but one and
the same instrument. If any term, provision, covenant or restriction of this
Amendment is held by a court of competent jurisdiction or other authority to be
invalid, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions of this Amendment shall remain in full force and
effect and shall in no way be affected, impaired or invalidated.

                                 THE DEBENTURES

2.01 Form and Dating.

      (a) General. The Debentures and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit A hereto. The
Debentures may have notations, legends or endorsements required by law, stock
market or exchange rule or usage; provided that any such notation, legend or
endorsement required by usage is in a form acceptable to the Company. Each
Debenture shall be dated the date of its authentication. The Debentures shall be
in denominations of $1,000 and integral multiples thereof.

      The terms and provisions contained in the Debentures shall constitute, and
are hereby expressly made, a part of this Indenture and the Company and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby. However, to the extent any
provision of any Debenture conflicts with the express provisions of this
Indenture, the provisions of this Indenture shall govern and be controlling.

      (b) Global Debentures. Debentures issued in global form shall be
substantially in the form of Exhibit A attached hereto (which Debenture shall
include the Global Debenture Legend and the "Schedule of Exchanges of Interests
in the Global Debenture" attached to Exhibit A hereto). Debentures issued in
definitive form shall be substantially in the form of Exhibit A attached hereto
(but without the Global Debenture Legend thereon and without the "Schedule of
Exchanges of Interests in the Global Debenture" attached thereto). Each Global
Debenture shall represent such of the outstanding Debentures as shall be
specified therein and each shall provide that it shall represent the aggregate
principal amount of outstanding Debentures from time to time endorsed thereon
and that the aggregate principal amount of outstanding Debentures repre-
<PAGE>
                                      -14-

sented thereby may from time to time be reduced or increased, as appropriate, to
reflect exchanges and redemptions. Any endorsement of a Global Debenture to
reflect the amount of any increase or decrease in the aggregate principal amount
of outstanding Debentures represented thereby shall be made by the Trustee or
the Custodian, at the direction of the Trustee, in accordance with instructions
given by the Holder thereof as required by Section 2.06 hereof.

      (c) Euroclear and Clearstream Procedures Applicable. The provisions of the
"Operating Procedures of the Euroclear System" and "Terms and Conditions
Governing Use of Euroclear" and the "General Terms and Conditions of
Clearstream" and "Customer Handbook" of Clearstream (or any successor document
setting forth the procedures, terms and/or conditions of Euroclear or
Clearstream, as applicable) in effect at the relevant time shall be applicable
to transfers of beneficial interests in the Regulation S Global Debentures that
are held by Participants through Euroclear or Clearstream, as applicable.

2.02 Execution and Authentication.

      An Officer shall sign the Debentures for the Company by manual or
facsimile signature.

      If the Officer whose signature is on a Debenture no longer holds that
office at the time a Debenture is authenticated, the Debenture shall
nevertheless be valid.

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

      The Trustee shall authenticate Debentures for original issue in the
aggregate principal amount not to exceed $125,000,000 ($150,000,000 if the
Initial Purchasers exercise in full their option to purchase additional
Debentures pursuant to the Purchase Agreement) upon a written order of the
Company signed by an Officer (an "AUTHENTICATION ORDER"). Each such written
order shall specify the amount of Debentures to be authenticated and the date on
which the Debentures are to be authenticated, whether the Debentures are to be
issued as certificated Debentures or Global Debentures or such other information
as the Trustee may reasonably request.

      The Trustee may appoint an authenticating agent acceptable to the Company
to authenticate Debentures. 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 Holders or the
Company.

      The Trustee shall have the right to decline to authenticate and deliver
any Debentures under this Indenture if the Trustee, being advised by counsel,
determines that such action may not lawfully be taken or if the Trustee in good
faith shall determine that such action would expose the Trustee to personal
liability.

2.03 Registrar, Paying Agent and Conversion Agent.

      The Company shall maintain an office or agency in the Borough of
Manhattan, The City of New York where (a) Debentures may be presented for
registration of transfer or for exchange ("REGISTRAR"), (b) Debentures may be
presented for payment ("PAYING AGENT") and (c) Debentures may be presented for
conversion (the "CONVERSION AGENT"). The Registrar shall keep a register of the
Debentures and of their transfer and exchange. The Company may appoint one or
more co-registrars and one or more additional paying agents. The term
"Registrar" includes any co-registrar, the term "Paying Agent" includes any
additional paying agent and the term "Conversion Agent" includes any additional
Conversion Agent. The Company may change any Paying Agent, Conversion Agent or
Registrar without notice to any Holder. The Company shall notify the Trustee in
writing of the name and address of any Agent not a party to this Indenture. If
the Company fails to appoint or maintain another entity as Registrar, Paying
Agent or Conversion Agent, the Trustee shall act as such. The Company or any of
its subsidiaries may act as Paying Agent, Registrar or Conversion Agent.

      The Company initially appoints The Depository Trust Company ("DTC") to act
as Depositary with respect to the Global Debentures.

      The Company initially appoints the Trustee to act as the Registrar, Paying
Agent and Conversion Agent and to act as Custodian with respect to the Global
Debentures.

2.04 Paying Agent to Hold Money in Trust.

      The Company shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium or Additional Amounts, if any, or interest on the Debentures,
and will promptly notify the Trustee of any default by the Company in making any
such payment. While any such default continues, the Trustee may require a Paying
Agent to pay all money held by it to the Trustee. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee. Upon payment
over to the Trustee, the Paying Agent (if other than the Company or a
subsidiary) shall have no further liability for the money. If the Company or a
subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust
fund for the benefit of the Holders all money held by it as Paying Agent. Upon
any bankruptcy or reorganization proceedings relating to the Company, the
Trustee shall serve as Paying Agent for the Debentures.

2.05 Holder Lists.

      The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
all Holders and shall otherwise comply with TIA Section 312(a). If the Trustee
is not the Registrar, the Company shall furnish to the Trustee at least seven
business days before each Interest Payment Date and at such other times as the
Trus-
<PAGE>
                                      -16-

tee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of the Holders of
Debentures and the Company shall otherwise comply with TIA Section 312(a).

2.06 Transfer and Exchange.

      (a) Transfer and Exchange of Global Debentures. A Global Debenture may not
be transferred except as a whole (but not in part) by the Depositary to a
nominee of the Depositary, by a nominee of the Depositary to the Depositary or
to another nominee of the Depositary, or by the Depositary or any such nominee
to a successor Depositary or a nominee of such successor Depositary. Global
Debentures will be exchanged by the Company for Definitive Debentures if (i) the
Company delivers to the Trustee notice from the Depositary that (A) the
Depositary is unwilling or unable to continue to act as Depositary for the
Global Debentures or (B) the Depositary is no longer a clearing agency
registered under the Exchange Act and, in either case, the Company fails to
appoint a successor Depositary within 90 days after the date of such notice from
the Depositary, (ii) the Company in its sole discretion determines that the
Global Debentures (in whole but not in part) should be exchanged for Definitive
Debentures and delivers a written notice to such effect to the Trustee or (iii)
upon request of the Trustee or Holders of a majority of the aggregate principal
amount of outstanding Debentures if there shall have occurred and be continuing
a Default or Event of Default with respect to the Debentures; provided that in
no event shall the Reg S Temporary Global Debenture be exchanged by the Company
for Definitive Debentures prior to (A) the expiration of the Distribution
Compliance Period and (B) the receipt by the Registrar of any certificate
identified by the Company and its counsel to be required pursuant to Rule 903 or
Rule 904 under the Securities Act. Upon the occurrence of any of the preceding
events in (i), (ii) or (iii) above, Definitive Debentures shall be issued in
such names as the Depositary shall instruct the Trustee. Global Debentures also
may be exchanged or replaced, in whole or in part, as provided in Sections 2.07
and 2.10 hereof. Every Debenture authenticated and delivered in exchange for, or
in lieu of, a Global Debenture or any portion thereof, pursuant to this Section
2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the
form of, and shall be, a Global Debenture. A Global Debenture may not be
exchanged for another Debenture other than as provided in this Section 2.06(a);
however, beneficial interests in a Global Debenture may be transferred and
exchanged as provided in Section 2.06(b), (c) or (h) hereof.

      (b) Transfer and Exchange of Beneficial Interests in the Global
Debentures. The transfer and exchange of beneficial interests in the Global
Debentures shall be effected through the Depositary, in accordance with the
provisions of this Indenture and the Applicable Procedures. Beneficial interests
in the Restricted Global Debentures shall be subject to restrictions on transfer
comparable to those set forth herein to the extent required by the Securities
Act. Transfers of beneficial interests in the Global Debentures also shall
require compliance with either subparagraph (i) or (ii) below, as applicable, as
well as one or more of the other following subparagraphs, as applicable:
<PAGE>
                                      -17-

            (i) Transfer of Beneficial Interests in the Same Global Debenture.
      Beneficial interests in any Restricted Global Debenture may be transferred
      to Persons who take delivery thereof in the form of a beneficial interest
      in the same Restricted Global Debenture in accordance with the transfer
      restrictions set forth in the Private Placement Legend; provided, however,
      that prior to expiration of the Distribution Compliance Period, transfer
      of beneficial interests in the Reg S Temporary Global Debenture may not be
      made to a U.S. Person or for the account or benefit of a U.S. Person.
      Beneficial interests in any Unrestricted Global Debenture may be
      transferred to Persons who take delivery thereof in the form of a
      beneficial interest in an Unrestricted Global Debenture. No written orders
      or instructions shall be required to be delivered to the Registrar to
      effect the transfers described in this Section 2.06(b)(i).

            (ii) All Other Transfers and Exchanges of Beneficial Interests in
      Global Debentures. In connection with all transfers and exchanges of
      beneficial interests that are not subject to Section 2.06(b)(i) above, the
      transferor of such beneficial interest must deliver to the Registrar
      either (A) (1) a written order from a Participant or an Indirect
      Participant given to the Depositary in accordance with the Applicable
      Procedures directing the Depositary to credit or cause to be credited a
      beneficial interest in another Global Debenture in an amount equal to the
      beneficial interests to be transferred or exchanged and (2) instructions
      given in accordance with the Applicable Procedures containing information
      regarding the Participant account to be credited with such increase or (B)
      (1) an order from a Participant or an Indirect Participant given to the

      upon the transfer or exchange of beneficial interests in the Reg S
      Temporary Global Debenture prior to (x) the expiration of the Distribution
      Compliance Period and (y) the receipt by the Registrar of any certificates
      identified by the Company or its counsel to be required pursuant to Rule
      903 and Rule 904 under the Securities Act. Upon satisfaction of all of the
      requirements for transfer or exchange of beneficial interests in Global
      Debentures contained in this Indenture and the Debentures or otherwise
      applicable under the Securities Act, the Trustee shall adjust the
      principal amount of the relevant Global Debenture(s) pursuant to Section
      2.06(h) hereof.

            (iii) Transfer of Beneficial Interests to Another Restricted Global
      Debenture. A beneficial interest in any Restricted Global Debenture may be
      transferred to a Person who takes delivery thereof in the form of a
      beneficial interest in another Restricted Global Debenture if the transfer
      complies with the requirements of Section 2.06(b)(ii) above and the
      Registrar receives the following:

<PAGE>
                                      -18-

                  (A) if the transferee will take delivery in the form of a
            beneficial interest in the 144A Global Debenture, then the
            transferor must deliver a certificate in the form of Exhibit B
            hereto, including the certifications in item (1) thereof; and

                  (B) if the transferee will take delivery in the form of a
            beneficial interest in the Reg S Temporary Global Debenture or the
            Reg S Permanent Global Debenture, then the transferor must deliver a
            certificate in the form of Exhibit B hereto, including the
            certifications in item (2) thereof.

            (iv) Transfer and Exchange of Beneficial Interests in a Restricted
      Global Debenture for Beneficial Interests in the Unrestricted Global
      Debenture. A beneficial interest in any Restricted Global Debenture may be
      exchanged by any holder thereof for a beneficial interest in an
      Unrestricted Global Debenture or transferred to a Person who takes
      delivery thereof in the form of a beneficial interest in an Unrestricted
      Global Debenture if the exchange or transfer complies with the
      requirements of Section 2.06(b)(ii) above and:

                  (A) such transfer is effected pursuant to the Shelf
            Registration Statement in accordance with the Registration Rights
            Agreement; or

                  (B) the Registrar receives the following:

                        (1) if the holder of such beneficial interest in a
                  Restricted Global Debenture proposes to exchange such
                  beneficial interest for a beneficial interest in an
                  Unrestricted Global Debenture, a certificate from such holder
                  in the form of Exhibit C hereto, including the certifications
                  in Item (1)(a) thereof; or

                        (2) if the holder of such beneficial interest in a
                  Restricted Global Debenture proposes to transfer such
                  beneficial interest to a Person who shall take delivery
                  thereof in the form of a beneficial interest in an
                  Unrestricted Global Debenture, a certificate from such holder
                  in the form of Exhibit C hereto, including the certifications
                  in item 1(a) thereof;

                  and, in each such case set forth in this subparagraph (iv), if
            the Registrar so requests or if the Applicable Procedures so
            require, an Opinion of Counsel in form, and from legal counsel,
            reasonably acceptable to the Registrar to the effect that such
            exchange or transfer is in compliance with the Securities Act and
            that the restrictions on transfer contained herein and in the
            Private Placement Legend are no longer required in order to maintain
            compliance with the Securities Act.

                  If any such transfer is effected pursuant to subparagraph (B)
            above at a time when an Unrestricted Global Debenture has not yet
            been issued, the Company shall issue and,
<PAGE>
                                      -19-

            upon receipt of an Authentication Order in accordance with Section
            2.02 hereof, the Trustee shall authenticate one or more Unrestricted
            Global Debentures in an aggregate principal amount equal to the
            aggregate principal amount of beneficial interests transferred
            pursuant to subparagraph (B) above.

                  Beneficial interests in an Unrestricted Global Debenture
            cannot be exchanged for, or transferred to Persons who take delivery
            thereof in the form of, a beneficial interest in a Restricted Global
            Debenture.

      (c) Transfer or Exchange of Beneficial Interests for Definitive
Debentures.

            (i) Beneficial Interests in Restricted Global Debentures to
      Restricted Definitive Debentures. If any holder of a beneficial interest
      in a Restricted Global Debenture proposes to exchange such beneficial
      interest for a Restricted Definitive Debenture or to transfer such
      beneficial interest to a Person who takes delivery thereof in the form of
      a Restricted Definitive Debenture, then, upon receipt by the Registrar of
      the following documentation:

                  (A) if the holder of such beneficial interest in a Restricted
            Global Debenture proposes to exchange such beneficial interest for a
            Restricted Definitive Debenture, a certificate from such holder in
            the form of Exhibit C hereto, including the certifications in item
            (2)(a) thereof;

                  (B) if such beneficial interest is being transferred to a QIB

            certifications in item (1) thereof;

                  (C) if such beneficial interest is being transferred to a
            Person other than a U.S. Person in an offshore transaction in
            accordance with Rule 903 or Rule 904 under the Securities Act, a
            certificate to the effect set forth in Exhibit B hereto, including
            the certifications in item (2) thereof;

                  (D) if such beneficial interest is being transferred pursuant

AS SPECIFIED IN THE INDENTURE (AS DEFINED HEREIN). NEITHER THE HOLDER NOR THE
BENEFICIAL OWNERS OF THIS REGULATION S TEMPORARY GLOBAL DEBENTURE SHALL BE
ENTITLED TO RECEIVE CASH PAYMENTS OF INTEREST DURING THE PERIOD WHICH SUCH
HOLDER HOLDS THIS DEBENTURE. NOTHING IN THIS LEGEND SHALL BE DEEMED TO PREVENT
INTEREST FROM ACCRUING ON THIS DEBENTURE."

      (g) Cancellation and/or Adjustment of Global Debentures. At such time as
all beneficial interests in a particular Global Debenture have been exchanged
for Definitive Debentures or a particular Global Debenture has been redeemed,
repurchased or canceled in whole and not in part, each such Global Debenture
shall be returned to or retained and canceled by the Trustee in accordance with
Section 2.11 hereof. At any time prior to such cancellation, if any beneficial
interest in a Global Debenture is exchanged for or transferred to a Person who
will take delivery thereof in the form of a beneficial interest in another
Global Debenture or for Definitive Debentures, the principal amount of
Debentures represented by such Global Debenture shall be reduced accordingly and
an endorsement shall be made on such Global Debenture by the Trustee or by the
Depositary at the direction of the Trustee to reflect such reduction; and if the
beneficial interest is being exchanged for or transferred to a Person who will
take delivery thereof in the form of a beneficial interest in another Global
Debenture, such other Global Debenture shall be increased

                                      -28-

accordingly and an endorsement shall be made on such Global Debenture by the
Trustee or by the Depositary at the direction of the Trustee to reflect such
increase.

      (h) General Provisions Relating to Transfers and Exchanges.

            (i) To permit registrations of transfers and exchanges, the Company
      shall execute and the Trustee shall authenticate Global Debentures and
      Definitive Debentures upon the Company's order or at the Registrar's
      request.

            (ii) No service charge shall be made to a holder of a beneficial
      interest in a Global Debenture or to a Holder of a Definitive Debenture
      for any registration of transfer or exchange, but the Company may require
      payment of a sum sufficient to cover any transfer tax or similar
      governmental charge payable in connection therewith (other than any such
      transfer taxes or similar governmental charge payable upon exchange or
      transfer pursuant to Sections 2.10, 3.06 and 9.05 hereof).

            (iii) The Registrar shall not be required to register the transfer
      of or exchange any Debenture selected for redemption in whole or in part,
      except the unredeemed portion of any Debenture being redeemed in part.

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

            (v) The Company shall not be required (A) to issue, to register the
      transfer of or to exchange any Debentures during a period beginning at the
      opening of business 15 days before the day of any selection of Debentures
      for redemption under Section 3.05 hereof and ending at the close of
      business on the earliest date on which the relevant Notice of Redemption
      is deemed to have been given to all Holders of Debentures to be redeemed,
      (B) to register the transfer of or to exchange any Debenture so selected
      for redemption in whole or in part, except the unredeemed portion of any
      Debenture being redeemed in part or (C) to register the transfer of or to
      exchange a Debenture between a record date and the next succeeding
      Interest Payment Date.

            (vi) Prior to due presentment for the registration of a transfer of
      any Debenture, the Trustee, any Agent and the Company may deem and treat
      the Person in whose name any Debenture is registered as the absolute owner
      of such Debenture for the purpose of receiving payment of principal of and
      interest on such Debentures and for all other purposes, and none of the
      Trustee, any Agent or the Company shall be affected by notice to the
      contrary.
<PAGE>
                                      -29-

            (vii) The Trustee shall authenticate Global Debentures and
      Definitive Debentures in accordance with the provisions of Section 2.02
      hereof.

            (viii) All certifications, certificates and Opinions of Counsel
      required to be submitted to the Registrar pursuant to this Section 2.06 to
      effect a registration of transfer or exchange may be submitted by
      facsimile.

            (ix) Each Holder agrees to indemnify the Company and the Trustee
      against any liability that may result from the transfer, exchange or
      assignment by such Holder of such Holder's Debenture in violation of any
      provision of this Indenture and/or applicable United States federal or
      state securities law.

            (x) The Trustee shall have no obligation or duty to monitor,
      determine or inquire as to compliance with any restrictions on transfer
      imposed under this Indenture or under applicable law with respect to any
      transfer of any interest in any Debenture (including any transfers between
      or among Depositary Participants or beneficial owners of interests in any
      Global Debenture) other than to require delivery of such certificates and
      other documentation or evidence as are expressly required by, and to do so
      if and when expressly required by the terms of, this Indenture, and to
      examine the same to determine substantial compliance as to form with the
      express requirements hereof.

2.07 Replacement Debentures.

      If any mutilated Debenture is surrendered to the Trustee or the Company
and the Trustee receives evidence to its satisfaction of the destruction, loss
or theft of any Debenture, the Company shall issue and the Trustee, upon receipt
of an Authentication Order, shall authenticate a replacement Debenture if the
Trustee's requirements are met. An indemnity bond must be supplied by the Holder
that is sufficient in the judgment of the Trustee and the Company to protect the
Company, the Trustee, any Agent and any authenticating agent from any loss that
any of them may suffer if a Debenture is replaced. The Company may charge for
its expenses in replacing a Debenture.

      Every replacement Debenture is an additional obligation of the Company and
shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Debentures duly issued hereunder.

2.08 Outstanding Debentures.

      The Debentures outstanding at any time are all the Debentures
authenticated by the Trustee except for those canceled by it, those delivered to
it for cancellation, those reductions in the interest in a Global Debenture
effected by the Trustee in accordance with the provisions hereof, and those
described in this Section 2.08 as not outstanding. Except as set forth in
Section 2.09
<PAGE>
                                      -30-

hereof, a Debenture does not cease to be outstanding because the Company or an
Affiliate of the Company holds the Debenture.

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

      If a Debenture is converted pursuant to Article 11 hereof, such Debenture
shall cease to be outstanding and interest thereon (including Contingent
Interest and Additional Amounts, if any) shall cease to accrue.

      If the principal amount of any Debenture is considered paid under Section
4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

      If the Paying Agent (other than the Company, a subsidiary or an Affiliate
of any thereof) holds, on a redemption date or maturity date, money sufficient
to pay Debentures payable on that date, then on and after that date such
Debentures shall be deemed to be no longer outstanding and shall cease to accrue
interest.

2.09 Treasury Debentures.

      In determining whether the Holders of the required principal amount of
Debentures have concurred in any direction, waiver or consent, Debentures owned
by the Company, or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company, shall
be considered as though not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Debentures as to which a Responsible Officer
of the Trustee has actual knowledge are so owned shall be so disregarded.

2.10 Temporary Debentures.

      Until certificates representing Debentures are ready for delivery, the
Company may prepare and the Trustee, upon receipt of an Authentication Order,
shall authenticate temporary Debentures. Temporary Debentures shall be
substantially in the form of certificated Debentures but may have variations
that the Company considers appropriate for temporary Debentures and as shall be
reasonably acceptable to the Trustee. Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate definitive Debentures in
exchange for temporary Debentures.

      Holders of temporary Debentures shall be entitled to all of the benefits
of this Indenture.
<PAGE>
                                      -31-

2.11 Cancellation.

      The Company at any time may deliver Debentures to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Debentures surrendered to them for registration of transfer, exchange or
payment. The Trustee and no one else shall cancel all Debentures surrendered for
registration of transfer, exchange, payment, replacement or cancellation and
shall dispose of canceled Debentures in accordance with its procedures for the
disposition of canceled securities in effect as of the date of such disposition
(subject to the record retention requirement of the Exchange Act). Certification
of the disposition of all canceled Debentures shall be delivered to the Company.
The Company may not issue new Debentures to replace Debentures that it has paid
or that have been delivered to the Trustee for cancellation.

2.12 Defaulted Interest.

      If the Company defaults in a payment of interest on the Debentures, it
shall pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest, to the Persons who are
Holders on a subsequent special record date, in each case at the rate provided
in the Debentures. 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. The Company shall fix or cause to be fixed each such special
record date and payment date, provided that no such special record date shall be
less than 10 days prior to the related payment date for such defaulted interest.
At least 15 days before the special record date, the Company (or, upon the
written request of the Company, the Trustee in the name and at the expense of
the Company) shall mail or cause to be mailed to Holders a notice that states
the special record date, the related payment date and the amount of such
interest to be paid.

2.13 CUSIP Numbers.

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

                                   ARTICLE 3

                            REDEMPTION AND PREPAYMENT

3.01 Optional Redemption.

      On or after October 15, 2013, the Company may redeem the Debentures for
cash in whole or in part, from time to time, in any integral multiple of $1,000,
at any time at the option of the Company upon not less than 30 nor more than 60
days notice at a redemption price (the "REDEMPTION PRICE") equal to 100% of the
principal amount thereof, together with accrued and unpaid interest, including
interest on any unpaid interest, compounded semi-annually (together with any
unpaid Contingent Interest, "COMPOUNDED INTEREST") thereon, up to but not
including the Redemption Date.

      If the Debentures are redeemed on any Interest Payment Date, accrued and
unpaid interest shall be payable to Holders of record on the relevant record
date. If a Debenture is redeemed on or after an interest record date but on or
prior to the related Interest Payment Date, then any accrued and unpaid interest
shall be paid to the Person to whom principal of such Debenture will be paid. If
any Debenture called for redemption shall not be so paid upon surrender for
redemption because of the failure of the Company to comply with the preceding
paragraph, interest shall be paid on the unpaid principal, from the redemption
date until such principal is paid, and to the extent lawful on any interest not
paid on such unpaid principal, in each case at the rate provided in the
Debentures.

      The Company may not redeem any Debentures unless all accrued and unpaid
interest thereon, including Compounded Interest, if any, has been or is
simultaneously paid for all semi-annual periods terminating on or prior to the
date of the Notice of Redemption.

3.02 Debentures Purchased in Part.

      Any Debenture that is to be purchased only in part shall be surrendered at
the office of the Paying Agent (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by, the Holder thereof or such
Holder's attorney duly authorized in writing) and the Company shall execute and
the Trustee shall authenticate and deliver to the Holder of such Debenture,
without service charge, a new Debenture or Debentures, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to,
and in exchange for, the portion of the principal amount of the Debenture so
surrendered which is not redeemed.

                                      -33-

3.03 Reserved.

3.04 Notices to Trustee.

      If the Company elects to redeem Debentures pursuant to the optional
redemption provisions set forth in Section 3.01 hereof, it shall furnish to the
Trustee, at least 30 days but not more than 60 days before a redemption date, an
Officers' Certificate setting forth (i) the clause of this Indenture pursuant to
which the redemption shall occur, (ii) the redemption date, (iii) the principal
amount of Debentures to be redeemed and (iv) the Redemption Price.

3.05 Selection of Debentures to Be Redeemed.

      If less than all of the Debentures are to be redeemed or purchased in an
offer to purchase at any time, the Trustee shall select the Debentures to be
redeemed or purchased among the Holders of the Debentures by lot, or on a pro
rata basis, or another method the Trustee considers fair and appropriate. In the
event of partial redemption by lot, the particular Debentures to be redeemed
shall be selected, unless otherwise provided herein, not less than 30 nor more
than 60 days prior to the redemption date by the Trustee from the outstanding
Debentures not previously called for redemption.

      The Trustee 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 and portions
of Debentures selected shall be in principal amounts of $1,000 or integral
multiples of $1,000; except that if all of the Debentures of a Holder are to be
redeemed, the entire outstanding amount of Debentures held by such Holder, even
if not a multiple of $1,000, shall be redeemed. Except as provided in the
preceding sentence, provisions of this Indenture that apply to Debentures called
for redemption also apply to portions of Debentures called for redemption.

      If any Debenture selected for partial redemption is converted in part
before termination of the conversion right with respect to the portion of the
Debenture so selected, the converted portion of such Debenture shall be deemed
(so far as possible) to be the portion selected for redemption. Debentures that
have been converted during a selection of Debentures to be redeemed may be
treated by the Trustee as outstanding for the purpose of such selection.

3.06 Notice of Redemption.

      At least 30 days but not more than 60 days before a redemption date, the
Company shall mail or cause to be mailed, by first class mail, a notice of
redemption (the "NOTICE OF REDEMPTION") to each Holder whose Debentures are to
be redeemed at its registered address.

      The notice shall identify the Debentures (including the CUSIP number, if
any) to be redeemed and shall state:
<PAGE>
                                      -34-

            (a) the Redemption Date;

            (b) the Redemption Price;

            (c) the current Conversion Price;

            (d) that the Debentures called for redemption may be converted at
      any time before the close of business on the second business day
      immediately preceding the Redemption Date;

            (e) if any Debenture is being redeemed in part, the portion of the
      principal amount of such Debenture to be redeemed and that, after the
      redemption date upon surrender of such Debenture, a new Debenture or
      Debentures in principal amount equal to the unredeemed portion shall be
      issued upon cancellation of the original Debenture;

            (f) the name and address of the Paying Agent and Conversion Agent;

            (g) that Holders who want to convert Debentures must satisfy the
      requirements set forth in paragraph 8 of the Debentures;

            (h) that Debentures called for redemption must be surrendered to the
      Paying Agent to collect the Redemption Price;

            (i) that, unless the Company defaults in making such redemption
      payment, interest on Debentures called for redemption ceases to accrue on
      and after the redemption date and the Debentures will cease to be
      convertible;

            (j) the paragraph of the Debentures and/or Section of this Indenture
      pursuant to which the Debentures called for redemption are being redeemed;
      and

            (k) that no representation is made as to the correctness or accuracy
      of the CUSIP number, if any, listed in such notice or printed on the
      Debentures.

      At the Company's request, the Trustee shall give the Notice of Redemption
in the Company's name and at its expense; provided that the Company shall have
delivered to the Trustee, at least 15 days prior to the date of the mailing of
such notice, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided
in the preceding paragraph.

3.07 Effect of Notice of Redemption.

      Once Notice of Redemption is mailed in accordance with Section 3.06
hereof, Debentures called for redemption become irrevocably due and payable on
the redemption date at the Redemption Price. A Notice of Redemption may not be
conditional.
<PAGE>
                                      -35-

3.08 Deposit of Redemption Price.

      The Company shall, by 12:00 noon, New York City time, on the Redemption
Date, deposit irrevocably with the Trustee or with the Paying Agent funds
sufficient to pay the Redemption Price and will give irrevocable instructions
and authority to pay such Redemption Price to the Holders of the Debentures. The
Trustee or the Paying Agent shall promptly return to the Company any money
deposited with the Trustee or the Paying Agent by the Company in excess of the
amounts necessary to pay the Redemption Price of, and accrued interest on, all
Debentures to be redeemed.

      If the Company complies with the provisions of the preceding paragraph, on
and after the Redemption Date, interest shall cease to accrue on the Debentures
or the portions of Debentures called for redemption, such Debentures will no
longer be deemed to be outstanding and all rights of Holders of such Debentures
so called for redemption will cease, except the right of the Holders of such
Debentures to receive the applicable Redemption Price, but without interest on
such Redemption Price. If any date fixed for redemption of Debentures is not a
business day, then payment of the Redemption Price payable on such date will be
made on the next succeeding day that is a business day (and without any interest
or other payment in respect of any such delay) except that, if such business day
falls in the next calendar year, such payment will be made on the immediately
preceding business day, in each case with the same force and effect as if made
on such date fixed for redemption. If the Company fails to repay the Debentures
on maturity or the date fixed for redemption, or if payment of the Redemption
Price in respect of Debentures is improperly withheld or refused and not paid by
the Company, interest on such Debentures will continue to accrue, from the
original Redemption Date to the date of payment, in which case the actual
payment date will be considered the date fixed for redemption for purposes of
calculating the applicable Redemption Price.

3.09 Debentures Redeemed in Part.

      Upon surrender of a Debenture that is redeemed in part, the Company shall
issue and, upon the Company's written request, the Trustee shall authenticate
for the Holder at the expense of the Company a new Debenture equal in principal
amount to the unredeemed portion of the Debenture surrendered.

      In the event of any redemption in part, the Company shall not be required
to (i) issue, register the transfer of or exchange any Debentures during a
period beginning at the opening of business 15 days before any selection for
redemption of Debentures and ending at the close of business on the earliest
date on which the relevant Notice of Redemption is deemed to have been given to
all Holders of Debentures to be redeemed and (ii) register the transfer of or
exchange any Debentures so selected for redemption, in whole or in part, except
the unredeemed portion of any Debentures being redeemed in part.

                                      -36-

3.10 Mandatory Redemption.

      The Company shall not be required to make sinking fund payments with
respect to the Debentures.

3.11 Purchase of Debentures at Option of the Holder upon Change of Control.

      (a) Subject to Section 3.11(b) below, if at any time that Debentures
remain outstanding there shall have occurred a Change of Control, Debentures
shall be repurchased by the Company, at the option of the Holder thereof, at a
purchase price in cash (the "CHANGE OF CONTROL REPURCHASE PRICE") equal to 100%
of the principal amount of the Debentures to be purchased plus accrued and
unpaid interest (including Additional Amounts, if any), thereon, up to but not
including the date (the "CHANGE OF CONTROL REPURCHASE DATE") fixed by the
Company that is no later than the 30th business day after the date the Company
Change of Control Offer Notice is given, subject to satisfaction by or on behalf
of the Holder of the requirements set forth in Section 3.11(d); provided that if
the Change of Control Repurchase Date is on or after an interest record date but
on or prior to the related Interest Payment Date, interest and Additional
Amounts, if any, will be payable to the Holders in whose names the Debentures
are registered at the close of business on the relevant record date.

      (b) Notwithstanding anything set forth in Section 3.11(a), the Company may
elect (which election shall be irrevocable) to pay the Change of Control
Repurchase Price in Common Stock, shares of Acquiror Securities that are
publicly traded securities, or a combination of cash, shares of Common Stock and
such publicly traded Acquiror Securities by so stating in the Company Change of
Control Offer Notice; provided, however, the Company shall not pay the Change of
Control Repurchase Price in Common Stock or Acquiror Securities if an Event of
Default has occurred or is continuing (other than an Event of Default that is
cured by the payment of the Change of Control Repurchase Price) and unless the
Company satisfies the other conditions prior to the Change of Control Repurchase
Date as set forth in Sections 3.11 and 3.13. In such event, the number of shares
of Common Stock or Acquiror Securities a Holder will receive will equal the
portion of the Change of Control Repurchase Price payable in such shares divided
by 95% of the average of the last reported sale price of Common Stock or
Acquiror Securities that are publicly traded securities, as the case may be, for
the five (5) days immediately preceding and including the third trading day
prior to the Change of Control Repurchase Date. All shares issued pursuant to
this Section 3.11(b) shall, upon issue, be duly and validly issued and fully
paid and non-assessable.

      (c) The Company shall mail to all Holders of record of the Debentures a
notice (a "COMPANY CHANGE OF CONTROL OFFER NOTICE") of the occurrence of a
Change of Control and of the repurchase right arising as a result thereof within
20 business days after the Company obtains knowledge of the occurrence of such
Change of Control. The Company shall promptly furnish to the Trustee a copy of
such notice. Each Company Change of Control Offer Notice shall in-

            (iii) the Change of Control Repurchase Price, the applicable
      conversion rate and any adjustments to the applicable conversion rate;

            (iv) the name and address of the Paying Agent and Conversion Agent;

      Change of Control Acceptance Notice has been withdrawn in accordance with
      the terms of this Indenture;

            (vi) that Debentures must be surrendered to the Paying Agent to
      collect payment of the Change of Control Repurchase Price and accrued but
      unpaid interest and Contingent Interest and Additional Amounts, if any;

            (vii) that the Change of Control Repurchase Price for any Debentures
      as to which a Holder Change of Control Acceptance Notice has been given
      and not withdrawn, together with any accrued and unpaid interest
      (including Contingent Interest and Additional Amounts, if any, with
      respect thereto, shall be paid promptly following the later of the Change
      of Control Repurchase Date and the time of surrender of such Debentures as
      described in (vi);

            (viii) the last date on which a Holder may exercise the Change of
      Control repurchase right;

            (ix) the Change of Control Repurchase Date;

            (x) whether the Company will pay the Change of Control Repurchase
      Price in cash, shares of Common Stock, Acquiror Securities or a
      combination thereof, specifying the percentage of each;

            (xi) the procedures the Holder must follow under this Section 3.11
      to require the Company to repurchase their Debentures;

            (xii) that, unless the Company defaults in making payment of such
      Change of Control Repurchase Price, interest (including Contingent
      Interest and Additional Amounts, if any), on Debentures covered by any
      Holder Change of Control Acceptance Notice will cease to accrue on and
      after the Change of Control Repurchase Date;
<PAGE>
                                      -38-

            (xiii) the CUSIP number of the Debentures; and

            (xiv) the procedures for withdrawing a Holder Change of Acceptance
      Notice (as specified in Section 3.12).

      At the Company's request and at the Company's expense, the Trustee shall
give the Company Change of Control Offer Notice in the Company's name; provided,
however, that, in all cases, the text of the Company Change of Control Offer
Notice shall be prepared by or at the direction of the Company.

      (d) For a Debenture to be so repurchased at the option of the Holder, the
Paying Agent must receive such Debenture duly endorsed for transfer, together
with the form entitled "Form of Holder Change of Control Acceptance Notice" (a
"HOLDER CHANGE OF CONTROL ACCEPTANCE NOTICE") on the reverse thereof duly
completed, together with such Debenture duly endorsed for transfer, prior to the
close of business on the 20th business day following the date of the Company
Change of Control Offer Notice, subject to extension to comply with applicable
law. The Holder Change of Control Acceptance Notice must state: (i) the
certificate numbers of the Debentures to be delivered for repurchase; (ii) the
portion of the principal amount of Debentures to be repurchased, which must be
$1,000 or an integral multiple thereof; and (iii) that the Debentures are to be
repurchased by the Company pursuant to Section 3.11 hereof. All questions as to
the validity, eligibility (including time of receipt) and acceptance of any
Debenture for redemption shall be determined by the Company, whose determination
shall be final and binding.

      The Company shall purchase from the Holder thereof, pursuant to this
Section 3.11, a portion of a Debenture if the principal amount of such portion
is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that
apply to the purchase of all of a Debenture also apply to the purchase of such
portion of such Debenture.

      Any purchase by the Company contemplated pursuant to the provisions of
this Section 3.11 shall be consummated by the delivery of the consideration to
be received by the Holder promptly following the later of the Change of Control
Repurchase Date and the time of delivery of the Debentures to the Paying Agent
in accordance with this Section 3.11.

      Notwithstanding anything herein to the contrary, any Holder delivering to
the Paying Agent the Holder Change of Control Acceptance Notice contemplated by
this Section 3.11(d) shall have the right to withdraw such Holder Change of
Control Acceptance Notice at any time prior to the close of business on the 20th
business day following the date of the Company Change of Control Offer Notice by
delivery of a written notice of withdrawal to the Paying Agent in accordance
with Section 3.12.

      The Paying Agent shall promptly notify the Company of the receipt by it of
any Holder Change of Control Acceptance Notice or written withdrawal thereof.
<PAGE>
                                      -39-

      Notwithstanding anything herein to the contrary, the Company's obligations
pursuant to this Section 3.11 shall be satisfied if a third party makes an offer
to repurchase outstanding Debentures after a Change of Control in the manner,
and at the times and otherwise in compliance in all material respects with the
requirements of this Section 3.11 and purchases all Debentures properly tendered
and not withdrawn pursuant to the requirements of this Section 3.11.

      In addition, the Company shall not be required to make a Change of Control
offer pursuant to this Section 3.11, if, in connection with or in contemplation
of any Change of Control, the Company has made an offer to purchase (an
"ALTERNATE OFFER") any and all Debentures validly tendered at a cash price equal
to or higher than the Change of Control Repurchase Price and has purchased all
Debentures properly tendered in accordance with the terms of such Alternate
Offer; provided, however, that the terms and conditions of such contemplated
Change of Control are described in reasonable detail to the Holders in the
notice delivered in connection with such Alternate Offer.

3.12 Effect of Holder Change of Control Acceptance Notice.

      Upon receipt by the Paying Agent of the Holder Change of Control
Acceptance Notice specified in Section 3.11(d), the Holder of the Debenture in
respect of which such Holder Change of Control Acceptance Notice was given shall
(unless such Holder Change of Control Acceptance Notice is withdrawn as
specified in the following two paragraphs) thereafter be entitled to receive
solely the Change of Control Repurchase Price, together with accrued but unpaid
interest (including Contingent Interest and Additional Amounts, if any),
thereon, to but not including the Change of Control Repurchase Date with respect
to such Debenture. Such Change of Control Repurchase Price, together with
accrued but unpaid interest (including Contingent Interest and Additional
Amounts, if any), thereon, to but not including the Change of Control Repurchase
Date shall be paid to such Holder, subject to receipt of funds by the Paying
Agent, promptly following the later of (x) the Change of Control Repurchase Date
with respect to such Debenture (provided that the conditions in Section 3.11
have been satisfied) and (y) the book-entry transfer or time of delivery of such
Debenture to the Paying Agent by the Holder thereof in the manner required by
Section 3.11(d). Debentures in respect of which a Holder Change of Control
Acceptance Notice has been given by the Holder thereof may not be converted
pursuant to Article 11 hereof on or after the date of the delivery of such
Holder Change of Control Acceptance Notice unless such Holder Change of Control
Acceptance Notice has first been validly withdrawn as specified in the following
two paragraphs.

      A Holder Change of Control Acceptance Notice may be withdrawn by means of
a written notice of withdrawal delivered to the office of the Paying Agent in
accordance with the Holder Change of Control Acceptance Notice prior to the
close of business on the 20th business day following the date of the Company
Change of Control Offer Notice. The notice of withdrawal must state:
<PAGE>
                                      -40-

            (i) the principal amount of the Debentures with respect to which
      such notice of withdrawal is being submitted;

            (ii) if certificated Debentures have been issued, the certificate
      numbers of the withdrawn Debentures; and

            (iii) the principal amount, if any, of such Debenture which remains
      subject to the original Holder Change of Control Acceptance Notice and
      which has been or will be delivered for purchase by the Company.

      The Company shall not purchase any of the Debentures pursuant to Section
3.11 if there has occurred prior to, on or after, as the case may be, the
giving, by the Holders of such Debentures, of the required Holder Change of
Control Acceptance Notice, and is continuing an Event of Default (other than a
default in the payment of the Change of Control Repurchase Price). The Paying
Agent will promptly return to the respective Holders thereof any Debentures (x)
with respect to which a Holder Change of Control Acceptance Notice has been
withdrawn in compliance with this Indenture, or (y) held by it during the
continuance of an Event of Default (other than a default in the payment of the
Change of Control Repurchase Price) in which case, upon such return, the Holder
Change of Control Acceptance Notice with respect thereto shall be deemed to have
been withdrawn.

3.13 Deposit of Change of Control Repurchase Price.

      Prior to the close of business (New York City time) on the business day
prior to the Change of Control Repurchase Date, the Company shall deposit with
the Trustee or with the Paying Agent (or, if the Company or a subsidiary or an
Affiliate of either of them is acting as the Paying Agent, shall segregate and
hold in trust as provided in Section 2.04) an amount of money (in immediately
available funds if deposited on such business day) or shares of Common Stock or
Acquiror Securities, as applicable, sufficient to pay the aggregate Change of
Control Repurchase Price together with accrued but unpaid interest (including
Contingent Interest and Additional Amount, if any) thereon, to but not including
the Change of Control Repurchase Date of all the Debentures or portions thereof
which are to be purchased as of the Change of Control Repurchase Date.

      If the Paying Agent holds money or securities sufficient to pay the Change
of Control Repurchase Price of the Debentures on the business day following the
Change of Control Repurchase Date, then, on and after such date: (a) the
Debentures will cease to be outstanding and interest will cease to accrue
(whether or not book-entry transfer of the Debentures has been made or the
Debentures have been delivered to the Paying Agent); and (b) all other rights of
the Holders will terminate (other than the right to receive the Change of
Control Repurchase Price upon transfer or delivery of the Debentures).
<PAGE>
                                      -41-

3.14 Repayment to the Company.

      The Trustee and the Paying Agent shall return to the Company any cash (or
shares of Common Stock or Acquiror Securities, as the case may be) that remains
unclaimed as provided in paragraph 6 of the Debentures, together with interest
or dividends, if any, thereon, held by them for the payment of the Change of
Control Repurchase Price and accrued but unpaid interest (including Contingent
Interest and Additional Amounts, if any); provided, however, that to the extent
that the aggregate amount of cash (or shares of Common Stock or Acquiror
Securities, as the case may be) deposited by the Company pursuant to Section
3.13 exceeds the aggregate Change of Control Repurchase Price of the Debentures
or portions thereof which the Company is obligated to purchase as of the Change
of Control Repurchase Date and accrued but unpaid interest thereon (including
Contingent Interest and Additional Amounts, if any), then, unless otherwise
agreed in writing with the Company, promptly after the Change of Control
Repurchase Date, the Trustee shall return any such excess to the Company
together with interest or dividends, if any, thereon.

3.15 Covenant to Comply with Securities Laws upon Purchase of Debentures.

      When complying with the provisions of Section 3.11 hereof (provided that
such offer or purchase constitutes an "issuer tender offer" for purposes of Rule
13e-4 (which term, as used herein, includes any successor provision thereto)
under the Exchange Act at the time of such offer or purchase), the Company shall
to the extent required (i) comply in all material respects with Rule 13e-4 and
Rule 14e-1 under the Exchange Act, (ii) file the related Schedule TO (or any
successor schedule, form or report) under the Exchange Act, and (iii) otherwise
comply in all material respects with all Federal and state securities laws so as
to permit the rights and obligations under Section 3.11 to be exercised in the
time and in the manner specified in Section 3.11.

                                   ARTICLE 4

                                    COVENANTS

4.01 Payment of Debentures.

      The Company shall pay or cause to be paid the principal of, premium, if
any, and interest (including Contingent Interest) on the Debentures on the dates
and in the manner provided in the Debentures, provided that

            (a) the Company will not pay interest accrued and unpaid on any
      Debentures that are converted into Common Stock. If a Holder converts
      after a record date for an interest payment but prior to the corresponding
      Interest Payment Date, it will receive the interest payable on the
      Interest Payment Date, notwithstanding the conversion of such
<PAGE>
                                      -42-

      Debentures prior to such Interest Payment Date, because that Holder will
      have been the Holder of record on the corresponding record date. However,
      at the time the Holder surrenders those Debentures for conversion, except
      as provided below, it must pay the Company an amount equal to the interest
      that will be paid on the Interest Payment Date. The preceding sentence
      does not apply, however, to a Holder that converts Debentures that are
      called by the Company for redemption. Accordingly, if the Company elects
      to redeem Debentures on a date after a record date for an interest payment
      but prior to the corresponding Interest Payment Date and prior to the
      Redemption Date, and the Holder of those Debentures chooses to convert the
      Debentures, the Holder will not be required to pay the Company, at the
      time it surrenders the Debentures for conversion, the amount of interest
      on the Debentures it will receive on the Interest Payment Date,

            (b) the Company will pay interest to a Person other than the Holder
      of record on the record date if the Company redeems the Debentures on a
      date that is after the record date and prior to the corresponding Interest
      Payment Date. In this instance, the Company will pay interest accrued and
      unpaid on the Debentures being redeemed, to, but not including the
      Redemption Date to the same Person to whom the Company will pay the
      principal of such Debentures, and

            (c) the Company's delivery to a Holder of shares of Common Stock
      into which a Debenture is convertible, together with any cash payment for
      such Holder's fractional shares, will be deemed to satisfy the Company's
      obligation to pay accrued tax original issue discount attributable to the
      period from the Issue Date through the conversion date. As a result,
      accrued tax original issue discount to the conversion date is deemed to be
      paid in full rather than cancelled, extinguished or forfeited.

Principal, premium, if any, and interest shall be considered paid on the date
due if the Paying Agent, if other than the Company or a subsidiary thereof,
holds as of 12:00 noon, New York City Time on the due date, money deposited by
the Company in immediately available funds and designated for and sufficient to
pay all principal, premium, if any, and interest then due. The Company shall pay
all Additional Amounts, if any, in the same manner on the dates and in the
amounts set forth in the Registration Rights Agreement.

      All references in this Indenture to "interest" shall include Compounded
Interest unless otherwise stated.

4.02 Maintenance of Office or Agency.

      The Company shall maintain in the Borough of Manhattan, The City of New
York, an office or agency (which may be an office of the Trustee or an Affiliate
of the Trustee, Registrar, co-registrar or Conversion Agent) where Debentures
may be surrendered for registration of transfer or for exchange 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
<PAGE>
                                      -43-

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
Corporate Trust Office of the Trustee.

      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 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 designates the Corporate Trust Office of the Trustee as
one such office or agency of the Company in accordance with Section 2.03.

4.03 Reports.

      (a) The Company shall file with the Trustee, within 15 days after it files
such annual and quarterly reports, information, documents and other reports with
the SEC, copies of its annual report and of the information, documents and other
reports (or copies of such portions of any of the foregoing as the SEC may by
rules and regulations prescribe) which the Company is required to file with the
SEC pursuant to Section 13 or 15(d) of the Exchange Act. In the event the
Company is at any time no longer subject to the reporting requirements of
Section 13 or 15(d) of the Exchange Act, it shall continue to provide the
Trustee with reports containing substantially the same information as would have
been required to be filed with the SEC had the Company continued to have been
subject to such reporting requirements. In addition, the Company shall comply
with the other provisions of TIA Section 314(a).

      (b) At any time when the Company is not subject to Section 13 or 15(d) of
the Exchange Act, for so long as any Debentures remain outstanding, the Company
shall furnish to the Holders and to prospective investors designated by such
Holders, upon their request, the information required to be delivered pursuant
to Rule 144A(d)(4) under the Securities Act.

4.04 Compliance Certificate.

      (a) The Company shall deliver to the Trustee, on or prior to the 100th day
after the end of each fiscal year of the Company (which on the date hereof is
December 31), an Officers' Certificate complying with Section 314(a)(4) of the
TIA, stating that a review of the activities of the Company during the preceding
fiscal year has been made under the supervision of the signing Officers with a
view to determining whether the Company has kept, observed, performed and
fulfilled its obligations under this Indenture, and further stating, as to each
such Officer signing such certificate, that to the best of his or her knowledge
the Company has kept, observed, per-
<PAGE>
                                      -44-

formed and fulfilled each and every covenant contained in this Indenture and is
not in default in the performance or observance of any of the terms, provisions
and conditions of this Indenture (or, if a Default or Event of Default shall
have occurred, describing all such Defaults or Events of Default of which he or
she may have knowledge and what action the Company is taking or proposes to take
with respect thereto) and that to the best of his or her knowledge no event has
occurred and remains in existence by reason of which payments on account of the
principal of or interest, if any, on the Debentures is prohibited or if such
event has occurred, a description of the event and what action the Company is
taking or proposes to take with respect thereto. The Company shall promptly
provide the Trustee with an Officers' Certificate notifying the Trustee of any
change in the fiscal year of the Company.

      (b) The Company shall, so long as any of the Debentures are outstanding,
deliver to the Trustee, as soon as possible, and in any event within five days
after any Officer becomes aware of any Default or Event of Default, an Officers'
Certificate specifying such Default or Event of Default and what action the
Company is taking or proposes to take with respect thereto.

4.05 Taxes.

      The Company shall pay, prior to delinquency, all material taxes,
assessments, and governmental levies except such as are contested in good faith
and by appropriate proceedings or where the failure to effect such payment is
not adverse in any material respect to the Holders of the Debentures.

4.06 Stay, Extension and Usury Laws.

      The Company covenants (to the extent that it may lawfully do so) that it
shall not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, that may affect the covenants or
the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it shall not, by resort to any such law, hinder, delay
or impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law has
been enacted.

4.07 Corporate Existence.

      Subject to Article 5 hereof, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence.

4.08 Tax Treatment of Debentures.

      The Company and the Holders and any beneficial owner of a Debenture, by
purchasing the Debentures, agree that (i) the Debentures are "contingent payment
debt instruments" as de-
<PAGE>
                                      -45-

fined in Treasury Regulations Section 1.1275-4(b), (ii) each Holder and any
beneficial owner of a Debenture shall be bound by the Company's application of
the Treasury Regulations to the Debentures, including the Company's
determination that the rate at which interest will be deemed to accrue on the
Debentures for United States federal income tax purposes will be 9.40%
compounded semi-annually, which is the rate comparable to the rate at which the
Company would borrow on a noncontingent, nonconvertible basis with terms and
conditions otherwise comparable to the Debentures, (iii) each Holder and any
beneficial owner of a Debenture shall use the projected payment schedule with
respect to the Debentures determined by the Company, as required by Treasury
Regulations Section 1.1275-4(b)(4)(iv), to determine its interest accruals and
adjustments as provided in Treasury Regulations Section 1.1275-4(b), and (iv)
the Company and each Holder and any beneficial owner of a Debenture will not
take any position on a tax return inconsistent with (i), (ii), or (iii), unless
required by applicable law.

      A Holder of Debentures may obtain the issue price, amount of original
issue discount, issue date, yield to maturity, comparable yield and projected
payment schedule for the Debentures by submitting a written request for such
information to the Company at Grey Global Group Inc., 777 Third Avenue, New
York, New York 10017, Attention: Corporate Secretary.

5.01 Mergers and Sales of Assets by the Company.

      The Company shall not consolidate with or merge into any other Person or
convey, transfer, sell or lease its properties and assets substantially as an
entirety to any Person, unless:

            (i) the Person formed by such consolidation or into or with which
      the Company is merged or the Person to which the Company's properties and
      assets are conveyed, transferred, sold or leased, is a corporation
      organized and existing under the laws of the United States, any State
      thereof or the District of Columbia and, if other than the Company, has
      expressly assumed all of the Company's obligations, including the payment
      of the principal of, and interest on, the Debentures and the performance
      of the other covenants under Article 4 of this Indenture; and

            (ii) immediately after giving effect to such transaction, no Default
      or Event of Default has occurred and is continuing under this Indenture.

5.02 Successor Corporation Substituted.

      Upon any consolidation, merger, or any conveyance, transfer, sale or lease
of the Company's properties and assets in accordance with Section 5.01 hereof,
the successor corporation formed by such consolidation, merger, conveyance,
transfer, sale or lease shall be substituted for (so that from and after the
date of such consolidation, merger, conveyance, transfer, sale or lease, the
provisions of this Indenture referring to the "Company" shall refer instead to
the successor corporation and not to the Company), and may exercise every right
and power of the Company under this Indenture with the same effect as if such
successor Person had been named as the Company herein; provided that the
predecessor Company shall not be relieved from the obligation to pay the
principal of and interest on the Debentures except in the case of a
consolidation, merger, conveyance, transfer, sale or lease of the Company's
assets that meets the requirements of Section 5.01 hereof.

                              DEFAULTS AND REMEDIES

6.01 Events of Default.

      Each of the following is an "EVENT OF DEFAULT" in respect of the
Debentures:

            (a) failure for 30 days to pay interest on the Debentures when due,
      whether or not such payment is prohibited by Article 10 of this Indenture;
      provided that a valid extension of the interest payment period by the
      Company during an Extension Period pursuant to this Indenture shall not
      constitute a default in the payment of interest for this purpose;

            (b) failure to pay principal on the Debentures when due whether at
      maturity, upon redemption, by declaration or otherwise, whether or not
      such payment is prohibited by Article 10 of this Indenture;

            (c) failure to observe or perform any covenant contained in Article
      4 of this Indenture for 90 days after written notice to the Company of
      such failure from the Trustee or the Holders of at least 25% in principal
      amount of the outstanding Debentures;

            (d) the Company's failure to comply with Sections 3.11 or 5.01;

            (e) a default in the Company's indebtedness with an aggregate amount
      outstanding in excess of $25.0 million (a) resulting from the failure to
      pay principal at maturity or (b) as a result of which the maturity of such
      indebtedness has been accelerated prior to its Stated Maturity;
<PAGE>
                                      -47-

            (f) the Company's failure to pay final judgments aggregating in
      excess of $25.0 million, which judgments are not paid, discharged or
      stayed for a period of not less than 60 days;

            (g) a court having competent jurisdiction enters a decree or order
      for (A) relief in respect of the Company in an involuntary case under any
      applicable Bankruptcy Law now or hereafter in effect, (B) appointment of a
      receiver, liquidator, assignee, custodian, trustee, sequestrator or
      similar official of the Company for all or substantially all of the
      property and assets of the Company or (C) the winding up or liquidation of
      the affairs of the Company and, in each case, such decree or order shall
      remain unstayed and in effect for a period of 60 consecutive days; or

            (h) the Company (A) commences a voluntary case under any applicable
      Bankruptcy Law now or hereafter in effect, or consents to the entry of an

      Company or for all or substantially all of the property and assets of the
      Company or (C) effects any general assignment for the benefit of
      creditors.

6.02 Acceleration.

      If any Event of Default (other than an Event of Default specified in
clause (g) or (h) of Section 6.01 hereof) with respect to the Company occurs and
is continuing, unless the principal of all Debentures shall have already become
due and payable, either the Trustee or the Holders of at least 25% in aggregate
principal amount of the then outstanding Debentures may declare the principal of
all the Debentures to be due and payable immediately in cash by written notice
to the Company (and to the Trustee if given by such Holders) and, if it is given
at the request of the Holders, the Trustee must specify the respective Event of
Default and that it is a "notice of acceleration" (the "ACCELERATION NOTICE").
Upon delivery of an Acceleration Notice, the principal of and accrued interest
(including Contingent Interest and Additional Amounts, if any) on all the
Debentures shall become immediately due and payable. Notwithstanding the
foregoing, if an Event of Default specified in clause (g) or (h) of Section 6.01
hereof occurs with respect to the Company all outstanding Debentures shall
become and be immediately due and payable without any declaration or other act
on the part of the Trustee or any Holder. The Holders of a majority in aggregate
principal amount of the then outstanding Debentures by written notice to the
Trustee may, on behalf of all of the Holders, rescind and cancel an acceleration
and its consequences if the rescission would not conflict with any judgment or
decree if all existing Events of Default have been cured or waived except the
nonpayment of principal or interest that has become due solely because of such
acceleration, if interest on overdue installments of interest (to the extent the
payment of such interest is lawful) and on overdue principal, which has become
due other-
<PAGE>
                                      -48-

wise than by such declaration of acceleration, has been paid, and in the event
of the cure or waiver of an Event of Default of the type described in Section
6.01(c), the Trustee has received an Officers' Certificate and an Opinion of
Counsel that such Event of Default has been cured or waived. No such rescission
shall affect any subsequent Default or impair any rights arising from a
subsequent Default.

6.03 Other Remedies.

      If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy to collect the payment of principal, premium and Additional
Amounts, if any, and interest on the Debentures or to enforce the performance of
any provision of the Debentures or this Indenture.

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

6.04 Waiver of Past Defaults.

      Holders of not less than a majority in aggregate principal amount of the
then outstanding Debentures by written notice to the Trustee may on behalf of
the Holders of all of the Debentures waive any past Default, except a Default in
the payment of the principal of, or interest on, the Debentures (unless such
Default has been cured and a sum sufficient to pay all matured installments of
interest and principal otherwise than by acceleration has been deposited with
the Trustee) or call for a redemption of the Debentures. Upon any such waiver,
such Default shall cease to exist, and any Event of Default arising therefrom
shall be deemed to have been cured for every purpose of this Indenture; but no
such waiver shall extend to any subsequent or other Default or impair any right
consequent thereon.

6.05 Control by Majority.

      Holders of a majority in aggregate outstanding principal amount of the
Debentures have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture, that
the Trustee determines may be unduly prejudicial to the rights of other Holders
of Debentures or that may involve the Trustee in personal liability.

6.06 Limitation on Suits.

      A Holder of a Debenture may pursue a remedy with respect to this Indenture
or the Debentures only if:
<PAGE>
                                      -49-

            (a) the Holder of a Debenture gives to the Trustee written notice of
      a continuing Event of Default;

            (b) such Holder of a Debenture or Holders of Debentures offer and,
      if requested, provide to the Trustee indemnity or security satisfactory to
      the Trustee against any loss, liability or expense; and

            (c) the Trustee does not comply with the request within 60 days
      after receipt of the request and the offer and, if requested, the
      provision of indemnity or security.

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

6.07 Rights of Holders of Debentures to Receive Payment.

      Notwithstanding any other provision of this Indenture, the right of any
Holder of a Debenture to receive payment of principal, premium and Additional
Amounts, if any, and interest on the Debenture, on or after the respective due
dates expressed in the Debenture or the right to receive shares of Common Stock
upon conversion of a Debenture, or to bring suit for the enforcement of any such
payment on or after such respective dates, shall not be impaired or affected
without the consent of such Holder.

6.08 Collection Suit by Trustee.

      If an Event of Default specified in Section 6.01(a) or (b) occurs and is
continuing, the Trustee is authorized to recover judgment in its own name and as
trustee of an express trust against the Company for the whole amount of
principal of, premium and Additional Amounts, if any, and interest (including
Contingent Interest, if any) remaining unpaid on the Debentures and interest
(including Contingent Interest, if any) on overdue principal and, to the extent
lawful, interest and such further amount as shall be sufficient to cover the
costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

6.09 Trustee May File Proofs of Claim.

      The Trustee is authorized to file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Debentures allowed in any judicial proceedings relative to the
Company (or any other obligor upon the Debentures), its creditors or its
property and shall be entitled and empowered to collect, receive and distribute
any money or other property payable or deliverable on any such claims and any
custodian 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
<PAGE>
                                      -50-

shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due to 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 7.07 hereof. To the extent that the
payment of any such compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof out of the estate in any such proceeding, shall be denied
for any reason, payment of the same shall be secured by a lien on, and shall be
paid out of, any and all distributions, dividends, money, securities and other
properties that the Holders may be entitled to receive in such proceeding
whether in liquidation or under any plan of reorganization or arrangement or
otherwise. 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, or to authorize the Trustee to vote in respect of
the claim of any Holder in any such proceeding.

6.10 Priorities.

      If the Trustee collects any money pursuant to this Article 6, it shall pay
out the money in the following order:

            First: to the Trustee, its agents and attorneys for amounts due
      under Section 7.07 hereof, including payment of all compensation, expense
      and liabilities incurred, and all advances made, by the Trustee and the
      costs and expenses of collection;

            Second: to Holders of Debentures for amounts due and unpaid on the
      Debentures and for any accrued but unpaid interest amounts (including
      Additional Amounts and Contingent Interest, if any, due in respect of the
      Debentures), ratably, without preference or priority of any kind,
      according to the amounts due and payable on the Debentures; and

            Third: to the Company or to such party as a court of competent
      jurisdiction shall direct.

      The Trustee may fix a record date and payment date for any payment to
Holders of Debentures pursuant to this Section 6.10.

6.11 Undertaking for Costs.

      In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section does not apply to a suit by the Trustee or a suit by a Holder of a
Debenture pursuant to Section 6.07 hereof.

affairs.

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

      However, the Trustee shall examine the certificates and opinions to

notice references the Debentures and this Indenture.

7.05  Notice of Defaults.

      If a Default or Event of Default occurs and is continuing and if it is
actually known to a Responsible Officer of the Trustee, the Trustee shall mail
to Holders of Debentures a notice of the Default or Event of Default within 90
days after it occurs. Except in the case of a Default or Event of Default in
payment of principal of, premium, if any, or interest on any Debenture, the
Trustee may withhold the notice if and so long as a trust committee of the Board
of Directors or Responsible Officers of the Trustee in good faith determines
that withholding the notice is in the interests of the Holders of the
Debentures.

7.06  Reports by Trustee to Holders of the Debentures.

      Within 60 days after each August 15 beginning with the August 15 following
the date of this Indenture, and for so long as Debentures remain outstanding,
the Trustee shall mail to the Holders of the Debentures a brief report dated as
of such reporting date that complies with TIA Section 313(a) (but if no event
described in TIA Section 313(a) has occurred within the twelve months preceding
the reporting date, no report need be transmitted). The Trustee also shall
comply with TIA Section 313(b)(2). The Trustee shall also transmit by mail all
reports as required by TIA Section 313(c).

      A copy of each report at the time of its mailing to the Holders of
Debentures shall be mailed to the Company and filed with the SEC and each stock

Section 313(d). The Company shall promptly notify the Trustee when the
Debentures are listed on any stock exchange or of any delisting thereof.

7.07  Compensation and Indemnity.

      The Company shall pay to the Trustee from time to time such compensation
for its acceptance of this Indenture and services hereunder as the Company and
the Trustee shall agree to in writing from time to time. 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 promptly upon request for
all reasonable disbursements, advances and expenses incurred or made by it in
addition to the compensation for its services. Such expenses shall include the
reasonable compensation, disbursements and expenses of the Trustee's agents and
counsel.

      The Company shall indemnify the Trustee and any predecessor Trustee and
their agents against any and all losses, liabilities or expenses incurred by it
arising out of or in connection with the acceptance or administration of its
duties under this Indenture, including the costs and expenses of enforcing this
Indenture against the Company (including this Section 7.07) and defending itself
against any claim (whether asserted by the Company or any Holder or any other
Person) or liability in connection with the exercise or performance of any of
its powers or duties hereunder, except to the extent any such loss, liability or
expense may be attributable to its negligence or willful misconduct. The Trustee
shall notify the Company promptly of any claim for which it may seek indemnity.
Failure by the Trustee to so notify the Company shall not relieve
<PAGE>
                                      -55-

the Company of its obligations hereunder. The Company shall defend the claim and
the Trustee shall cooperate in the defense. The Trustee may have separate
counsel and the Company shall pay the reasonable fees and expenses of such
counsel. The Company need not pay for any settlement made without its consent,
which shall not be unreasonably withheld.

      To secure the Company's payment obligations in this Section 7.07, the
Trustee shall have a lien prior to the Debentures on all money or property held
or collected by the Trustee, except that held in trust to pay principal and
interest on particular Debentures. Such lien shall survive the satisfaction and
discharge of this Indenture and the resignation or removal of the Trustee.

      When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(g) or (h) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

      The Trustee shall comply with the provisions of TIA Section 313(b)(2) to
the extent applicable.

      The obligations of the Company under this Section 7.07 shall survive the
satisfaction and discharge of this Indenture and the resignation or removal of
the Trustee.

7.08  Replacement of Trustee.

      A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section 7.08.

      The Trustee may resign in writing at any time and be discharged from the
trust hereby created by so notifying the Company. The Holders of a majority in
principal amount of the then outstanding Debentures may remove the Trustee by so
notifying the Trustee and the Company in writing. The Company may remove the
Trustee if:

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

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

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

            (d)   the Trustee becomes incapable of acting.

      If the Trustee resigns or is removed or if a vacancy exists in the office
of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the then outstanding
<PAGE>
                                      -56-

Debentures may appoint a successor Trustee to replace the successor Trustee
appointed by the Company.

      If a successor Trustee does not take office within 90 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company, or
the Holders of at least 10% in principal amount of the then outstanding
Debentures may, at the expense of the Company, petition any court of competent
jurisdiction for the appointment of a successor Trustee.

      If the Trustee, after written request by any Holder who has been a Holder
for at least six months, fails to comply with Section 7.10, such Holder may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

      A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to the Company. Thereupon, the resignation or
removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture. The successor Trustee shall mail a notice of its succession to
Holders. The retiring Trustee shall promptly transfer all property held by it as
Trustee to the successor Trustee, provided all sums owing to the Trustee
hereunder have been paid and subject to the lien provided for in Section 7.07
hereof. Notwithstanding replacement of the Trustee pursuant to this Section
7.08, the Company's obligations under Section 7.07 hereof shall continue for the
benefit of the retiring Trustee.

7.09  Successor Trustee by Merger, etc.

      If the Trustee consolidates, merges or converts into, or transfers all or
substantially all of its corporate trust business to, another corporation, the
successor corporation without any further act or document shall be the successor
Trustee.

7.10  Eligibility; Disqualification.

      There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $10 million
as set forth in its most recent published annual report of condition.

      This Indenture shall always have a Trustee who satisfies the requirements
of TIA Section 310(a)(1), (2) and (5). The Trustee is subject to TIA Section
310(b).
<PAGE>
                                      -57-

7.11  Preferential Collection of Claims Against Company.

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

                                    ARTICLE 8

                           SATISFACTION AND DISCHARGE

8.01  Satisfaction and Discharge.

      This Indenture will be discharged and will cease to be of further effect
as to all Debentures issued hereunder, if:

  (1) either:

      (a)   all Debentures that have been authenticated (except lost, stolen or
            destroyed Debentures that have been replaced or paid and Debentures
            for whose payment money has theretofore been deposited in trust and
            thereafter repaid to the Company) have been delivered to the Trustee
            for cancellation; or

      (b)   all Debentures that have not previously been delivered to the
            Trustee for cancellation have become due and payable whether
            at Stated Maturity or any Redemption Date or any Repurchase
            Date, or upon conversion or otherwise, and the Company has
            irrevocably deposited or caused to be deposited with the
            Trustee as trust funds in trust solely for the benefit of the
            Holders, cash in U.S. dollars and/or shares of Common Stock
            (as applicable under the terms of this Indenture) in such
            amounts as will be sufficient without consideration of any
            reinvestment of interest, to pay and discharge the entire
            indebtedness on the Debentures not delivered to the Trustee
            for cancellation for principal, premium and Additional
            Amounts, if any, and accrued interest (including Contingent
            Interest, if any) to the date of maturity or redemption;

  (2) the Company has paid or caused to be paid all sums payable by it
      under this Indenture; and

  (3) the Company has delivered irrevocable instructions to the Trustee under
      this Indenture to apply the deposited money toward the payment of the
      Debentures at maturity or the redemption date, as the case may be.
<PAGE>
                                      -58-

In addition, the Company must deliver an Officers' Certificate and an Opinion of
Counsel to the Trustee stating that all conditions precedent to satisfaction and
discharge have been satisfied.

      Notwithstanding the satisfaction and discharge of this Indenture, if money
shall have been deposited with the Trustee pursuant to subclause (b) of clause
(1) of this Section 8.01, the provisions of Section 8.02 shall survive.

8.02  Application of Trust Money.

      All money deposited with the Trustee pursuant to Section 8.01 shall be
held in trust and applied by it, in accordance with the provisions of the
Debentures and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal (and
premium, if any) and interest (including Contingent Interest, if any) for whose
payment such money has been deposited with the Trustee; but such money need not
be segregated from other funds except to the extent required by law.

      If the Trustee or Paying Agent is unable to apply any money in accordance
with Section 8.01 by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Debentures shall be revived and reinstated as though no
deposit had occurred pursuant to Section 8.01; provided that if the Company has
made any payment of principal of, premium and Additional Amounts, if any, or
interest (including Contingent Interest, if any) on any Debentures because of
the reinstatement of its obligations, the Company shall be subrogated to the
rights of the Holders of such Debentures to receive such payment from the money
held by the Trustee or Paying Agent.

                                    ARTICLE 9

                        AMENDMENT, SUPPLEMENT AND WAIVER

9.01  Without Consent of Holders of Debentures.

      Notwithstanding Section 9.02 of this Indenture, the Company and the
Trustee may amend or supplement this Indenture or the Debentures without the
consent of any Holder of a Debenture:

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

            (b)   to provide for uncertificated Debentures in addition to
      certificated Debentures;
<PAGE>
                                      -59-

            (c)   to provide for the assumption of the Company's
      obligations to the Holders of the Debentures by a successor to the
      Company pursuant to Article 5 hereof;

            (d) to make any change that would provide any additional rights or
      benefits to the Holders of the Debentures or that does not adversely
      affect the rights of any Holder of the Debentures;

            (e)   to comply with any requirements under the TIA; or

            (f)   to appoint a successor trustee under this Indenture.

      Upon the request of the Company accompanied by a resolution of its Board
of Directors authorizing the execution of any such amended or supplemental
Indenture, and upon receipt by the Trustee of the documents described in Section
7.02 hereof, the Trustee shall join with the Company in the execution of any
amended or supplemental Indenture authorized or permitted by the terms of this
Indenture and to make any further appropriate agreements and stipulations that
may be therein contained, but the Trustee shall not be obligated to enter into
such amended or supplemental Indenture that affects its own rights, duties or
immunities under this Indenture or otherwise.

9.02  With Consent of Holders of Debentures.

      Except as provided below in this Section 9.02, the Company and the Trustee
may amend or supplement this Indenture and the Debentures with the consent of
the Holders of at least a majority in principal amount of the Debentures then
outstanding voting as a single class (including consents obtained in connection
with a tender offer or exchange offer for, or purchase of, the Debentures), and,
subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of
Default (other than a Default or Event of Default in the payment of the
principal of, premium and Additional Amounts, if any, or interest (including
Contingent Interest, if any) on the Debentures, except a payment default
resulting from an acceleration that has been rescinded) or compliance with any
provision of this Indenture or the Debentures may be waived with the consent of
the Holders of a majority in principal amount of the then outstanding Debentures
voting as a single class (including consents obtained in connection with a
tender offer or exchange offer for, or purchase of, the Debentures).

      Upon the request of the Company accompanied by a resolution of its Board
of Directors authorizing the execution of any such amended or supplemental
Indenture, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Debentures as aforesaid, and upon
receipt by the Trustee of the documents described in Section 7.02 hereof, the
Trustee shall join with the Company in the execution of such amended or
supplemental Indenture unless such amended or supplemental Indenture directly
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise, in which case the Trustee may in its discretion, but shall not be
obligated to, enter into such amended or supplemental Indenture.
<PAGE>
                                      -60-

      It shall not be necessary for the consent of the Holders of Debentures
under this 9.02 to approve the particular form of any proposed amendment or
waiver, but it shall be sufficient if such consent approves the substance
thereof.

      After an amendment, supplement or waiver under this Section 9.02 becomes
effective, the Company shall mail to the Holders of Debentures 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 amended or supplemental
Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a
majority in aggregate principal amount of the Debentures then outstanding voting
as a single class may waive compliance in a particular instance by the Company
with any provision of this Indenture or the Debentures. However, without the
consent of each Holder affected, an amendment or waiver under this Section 9.02
may not (with respect to any Debentures held by a non-consenting Holder):

            (a) reduce the principal amount of Debentures whose Holders must
      consent to an amendment, supplement, modification or waiver of this
      Indenture or the Debentures;

            (b)   reduce the principal of or change the Stated Maturity of
      any Debenture;

            (c) reduce the rate of or change the time for payment of interest,
      including Contingent Interest and Additional Amounts, or the applicable
      Redemption Dates on any Debenture;

            (d)   impair the right to institute suit for the enforcement
      of the right to receive any payment on or with respect to any
      Debenture when due;

            (e)   make any Debenture payable in currency other than that
      stated in the Debenture;

            (f) change the amount or time of any payment required after the
      obligation to make such payment arises or change the time before which no
      repurchase may be made;

            (g)   waive the right of such Holder to receive payment of the
      principal of or interest on any debenture, or any repurchase payment
      when due;

            (h)   impair the right of any Holder to convert any debenture;

            (i) modify the provisions of this Indenture relating to the
      Company's requirement to make an offer to repurchase the Debentures upon a
      Change of Control after the occurrence thereof;
<PAGE>
                                      -61-

            (j)   modify the subordination provisions of Article 10 hereof
      in a manner that adversely affects the rights of such Holder; or

            (k) take any other action otherwise prohibited by this Indenture to
      be taken without the consent of each Holder affected by such action.

9.03  Compliance with Trust Indenture Act.

      Every amendment or supplement to this Indenture or the Debentures shall be
set forth in an amended or supplemental indenture that complies with the TIA as
then in effect.

9.04  Revocation and Effect of Consents.

      Until an amendment, supplement or waiver becomes effective, a consent to
it by a Holder of a Debenture is a continuing consent by the Holder of a
Debenture and every subsequent Holder of a Debenture or portion of a Debenture
that evidences the same debt as the consenting Holder's Debenture, even if
notation of the consent is not made on any Debenture. However, any such Holder
of a Debenture or subsequent Holder of a Debenture may revoke the consent as to
its Debenture if the Trustee receives written notice of revocation before the
date the waiver, supplement or amendment becomes effective. An amendment,
supplement or waiver becomes effective in accordance with its terms and
thereafter binds every Holder.

9.05  Notation on or Exchange of Debentures.

      The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Debenture thereafter authenticated. The Company in
exchange for all Debentures may issue and the Trustee shall, upon receipt of an
Authentication Order, authenticate new Debentures that reflect the amendment,
supplement or waiver.

      Failure to make the appropriate notation or issue a new Debenture shall
not affect the validity and effect of such amendment, supplement or waiver.

9.06  Trustee to Sign Amendments, etc.

      The Trustee shall sign any amended or supplemental indenture authorized
pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Company
may not sign an amendment or supplemental indenture until the Board of Directors
approves it. In executing any amended or supplemental indenture, the Trustee
shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully
protected in relying upon an Officers' Certificate and an Opinion of Counsel
each stating that the amendment or supplement is authorized or permitted by this
Indenture and each complying with the requirements of Section 12.04 hereof. The
Trustee may, but shall not be obligated to, enter
<PAGE>
                                      -62-

into any such amended or supplemental indenture which affects the Trustee's own
rights, duties, liabilities or immunities under this Indenture or otherwise.

                                   ARTICLE 10

                                  SUBORDINATION

10.01 Agreement to Subordinate.

      The Company agrees, and each Holder by accepting a Debenture agrees, that
the indebtedness evidenced by the Debentures is subordinated in right of
payment, to the extent and in the manner provided in this Article 10, to the
prior payment in full, in cash or cash equivalents, of all Senior Debt (whether
outstanding on the date hereof or hereafter created, incurred, assumed or
guaranteed), and that the subordination is for the benefit of the holders of
Senior Debt, including Senior Debt incurred after the date of this Indenture.

      This Article 10 shall constitute a continuing offer to all Persons who, in
reliance upon such provisions, become holders of, or continue to hold, Senior
Debt, and such provisions are made for the benefit of the holders of Senior Debt
and such holders are made obligees hereunder and any one or more of them may
enforce such provisions.

      For purposes of this Article 10, a distribution may consist of cash,
securities or other property, by set-off or otherwise.

10.02 Liquidation; Dissolution; Bankruptcy.

      Upon any payment or distribution of assets of the Company to creditors of
the Company upon any liquidation, dissolution, winding up, receivership,
reorganization, assignment for the benefit of creditors, marshaling of assets
and liabilities or any bankruptcy, insolvency or similar proceeding relating to
the Company or its property, in an assignment for the benefit of creditors or
any marshaling of the Company's assets and liabilities:

              (i) the holders of all Senior Debt shall first be entitled to
      receive payment in full in cash or cash equivalents of all amounts due or
      to become due in respect of such Senior Debt (including interest after the
      commencement of any such proceeding at the rate specified in the
      applicable Senior Debt) before Holders of the Debentures shall be entitled
      to receive any payment with respect of the principal of, or interest on,
      the Debentures; and
<PAGE>
                                      -63-

              (ii)until all amounts due with respect to Senior Debt (as provided
      in clause (i) above) are paid in full, any distribution to which Holders
      would be entitled but for this Article 10 shall be made to holders of
      Senior Debt.

10.03 Default on Senior Debt or Designated Senior Debt.

      (a) The Company may not make any payment or distribution to the Trustee or
any Holder on account of principal, premium, if any, or interest in respect of
the Debentures if there shall have occurred and be continuing a default in any
payment with respect to Senior Debt (other than obligations in respect of
clauses (ii), (iii) and (iv) of the definition of "Qualifying Deferred
Compensation" and reasonable expense reimbursements due to the Company's and its
subsidiaries' employees and directors), whether at maturity, upon redemption, by
declaration of acceleration or otherwise (a "PAYMENT DEFAULT").

      (b) During the continuance of any other event of default (other than a
Payment Default) with respect to Designated Senior Debt pursuant to which the
maturity thereof may be accelerated, from and after the date of receipt by the
Trustee of written notice (a "PAYMENT BLOCKAGE NOTICE") from holders of such
Designated Senior Debt or from any Representative thereof, no payments on
account of principal, premium, if any, or interest in respect of the Debentures
may be made during a period (the "PAYMENT BLOCKAGE PERIOD") commencing on the
date of receipt of such Payment Blockage Notice and ending on the date such
event of default has been cured or waived or has ceased to exist, but in no
event shall any Payment Blockage Period extend beyond October 15, 2033.

10.04 Acceleration of Debentures.

      If payment of the Debentures is accelerated because of an Event of
Default, the Company shall promptly notify holders of Senior Debt of the
acceleration.

10.05 When Distribution Must Be Paid Over.

      In the event that the Trustee or any Holder receives any payment of any
obligations with respect to the Debentures when the payment is prohibited by
Section 10.03 hereof, such payment shall be held by the Trustee or such Holder,
in trust for the benefit of, and shall be paid forthwith over and delivered,
upon written request, to, the holders of Senior Debt as their interests may
appear or their Representative under an agreement (if any) pursuant to which
Senior Debt may have been issued, as their respective interests may appear, for
application to the payment of all obligations with respect to Senior Debt
remaining unpaid to the extent necessary to pay such obligations in full in
accordance with their terms, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Debt.
<PAGE>
                                      -64-

10.06 Notice by Company.

      The Company shall promptly notify the Trustee and the Paying Agent of any
facts known to the Company that would cause a payment of any obligations with
respect to the Debentures to violate this Article 10, but failure to give such
notice shall not affect the subordination of the Debentures to the Senior Debt
as provided in this Article 10.

10.07 Subrogation.

      After all Senior Debt is paid in full and until the Debentures are paid in
full, Holders of Debentures shall be subrogated to the rights of holders of
Senior Debt to receive distributions applicable to Senior Debt to the extent
that distributions otherwise payable to the Holders of Debentures have been
applied to the payment of Senior Debt. A distribution made under this Article 10
to holders of Senior Debt that otherwise would have been made to Holders of
Debentures is not, as between the Company and Holders, a payment by the Company
on the Debentures.

10.08 Relative Rights.

      This Article 10 defines the relative rights of Holders of Debentures and
holders of Senior Debt. Nothing in this Indenture shall:

              (i) impair, as between the Company and Holders of Debentures, the
      obligation of the Company, which is absolute and unconditional, to pay
      principal of and interest on the Debentures in accordance with their
      terms;

              (ii)affect the relative rights of Holders of Debentures and
      creditors of the Company other than their rights in relation to holders of
      Senior Debt; or

              (iii) prevent the Trustee or any Holder of Debentures from
      exercising its available remedies upon a Default or Event of Default,
      subject to the rights of holders and owners of Senior Debt to receive
      distributions and payments otherwise payable to Holders of Debentures.

      If the Company fails because of this Article 10 to pay principal of or
interest on a Debenture on the due date, the failure is still a Default or Event
of Default.

10.09 Subordination May Not Be Impaired by Company.

      No right of any present or future holder of Senior Debt to enforce the
subordination of the indebtedness evidenced by the Debentures shall in any way
be prejudiced or impaired by any act or failure to act by the Company or any
Holder or by the failure of the Company or any Holder to comply with the terms
of this Indenture, regardless of any knowledge thereof any such holder of Senior
Debt may have or otherwise be charged with.
<PAGE>
                                      -65-

      Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Debt may, at any time and from time to time, without the
consent of or notice to the Trustee, without incurring responsibility to the
Trustee or the Holders of the Debentures and without impairing or releasing the
subordination provided in this Article 10 or the obligations hereunder of the
Holders of the Debentures to the holders of the Senior Debt, do any one or more
of the following: (i) change the manner, place or terms of payment or extend the
time of payment of, or renew or alter, Senior Debt, or otherwise amend or
supplement in any manner Senior Debt, or any instrument evidencing the same or
any agreement under which Senior Debt is outstanding; (ii) sell, exchange,
release or otherwise deal with any property pledged, mortgaged or otherwise
securing Senior Debt; (iii) release any Person liable in any manner for the
payment or collection of Senior Debt; and (iv) exercise or refrain from
exercising any rights against the Company and any other Person.

10.10 Distribution or Notice to Representative.

      Whenever a distribution is to be made or a notice given to holders of
Senior Debt, the distribution may be made and the notice given to their
respective Representatives.

      Upon any payment or distribution of assets of the Company referred to in
this Article 10, the Trustee and the Holders of Debentures shall be entitled to
rely upon any order or decree made by any court of competent jurisdiction or
upon any certificate of any Representatives or of the liquidating trustee or
agent or other Person making any distribution to the Trustee or to the Holders
of Debentures for the purpose of ascertaining the Persons entitled to
participate in such distribution, the holders of the Senior Debt and other
indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article 10.

10.11 Rights of Trustee and Paying Agent.

      The Trustee shall not be deemed to owe any fiduciary duty to the holders
of Senior Debt and shall not be liable to any such holders (other than for its
willful misconduct or negligence) if the Trustee shall in good faith mistakenly
pay over or distribute to Holders of Debentures or to the Company or to any
other Person cash, property or securities to which any holders of Senior Debt
shall be entitled by virtue of this Article 10 or otherwise. With respect to the
holders of Senior Debt, the Trustee undertakes to perform or to observe only
such of its covenants or obligations as are specifically set forth in this
Indenture and no implied covenants or obligations with respect to holders of
Senior Debt shall be read into this Indenture against the Trustee.

      Notwithstanding the provisions of this Article 10 or any other provision
of this Indenture, the Trustee shall not be charged with knowledge of the
existence of any facts that would prohibit the making of any payment or
distribution by the Trustee, and the Trustee and the Paying Agent may continue
to make payments on the Debentures, unless the Trustee shall have received at
its Corporate Trust Office at least five business days prior to the date of such
payment written notice
<PAGE>
                                      -66-

of facts that would cause the payment of any obligations with respect to the
Debentures to violate this Article 10. Only the Company or a Representative may
give the notice. Nothing in this Article 10 shall impair the claims of, or
payments to, the Trustee under or pursuant to Section 7.07 hereof.

      The Trustee in its individual or any other capacity may hold Senior Debt
with the same rights it would have if it were not Trustee. Any Agent may do the
same with like rights.

10.12 Authorization to Effect Subordination.

      Each Holder of Debentures, by the Holder's acceptance thereof, authorizes
and directs the Trustee on such Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in this
Article 10, and appoints the Trustee to act as such Holder's attorney-in-fact
for any and all such purposes. If the Trustee does not file a proper proof of
claim or proof of debt in the form required in any proceeding referred to in
Section 6.09 hereof at least 30 days before the expiration of the time to file
such claim, the Representatives are hereby authorized to file an appropriate
claim for and on behalf of the Holders of the Debentures.

                                   ARTICLE 11

                          CONVERSION OF THE SECURITIES

11.01 Conversion Privilege.

      Prior to the close of business on the business day immediately preceding
October 15, 2033 (the "CONVERSION EXPIRATION DATE") and subject to the
provisions of this Article 11, a Holder may convert Debentures into shares of
Common Stock at an initial conversion rate of 1.0404 shares of Common Stock for
each $1,000 principal amount of Debentures (equivalent to a conversion price of
$961.20 per share of Common Stock (the "INITIAL CONVERSION PRICE")), subject to
adjustment pursuant to Section 11.06 (the Initial Conversion Price as so
adjusted from time to time, the "CONVERSION PRICE") during each of the following
periods (each such period, a "PERMITTED CONVERSION PERIOD"):

            (a) during the fiscal quarter immediately following each fiscal
      quarter (such previous fiscal quarter, the "PRIOR FISCAL QUARTER") in
      which the Market Price Condition has been satisfied,

            (b) during the period beginning on the date the Debentures are
      called for redemption and ending at the close of business on the business
      day immediately prior to the Redemption Date,
<PAGE>
                                      -67-

            (c)   during the five (5) consecutive business days after the
      Trading Price Condition has been satisfied,

            (d) during a Dividend Payment Period; provided that this clause (d)
      shall not apply with respect to a Holder that is otherwise permitted to,
      elects to and in fact does participate in the dividend or distribution (on
      an as-if-converted basis) giving rise to such right of conversion, and

            (e) during the period commencing on the date a Company Change of
      Control Offer Notice is mailed to Holders pursuant to Section 3.11(c) and
      ending thirty (30) days after the Company gives such notice.

      In addition, if the Company is a party to a consolidation, merger or
binding share exchange, in each case, pursuant to which Common Stock would be
converted into cash or property other than securities, a Holder may surrender
Debentures for conversion at any time from and after the date that is 15 days
prior to the anticipated effective date of such transaction until 15 days after
the actual effective date of such transaction. The Board of Directors shall
determine the anticipated effective date of the transaction, and such
determination shall be conclusive and binding on the holders and shall be
publicly announced by the Company by publication on its website or through such
other public medium as it may use at that time not later than two (2) business
days prior to such fifteenth day.

      A Debenture in respect of which a Holder elects to exercise its option to
require repurchase pursuant to Section 3.11 may be converted only if such Holder
withdraws its election in accordance with Section 3.11(d) and Section 3.12. A
Holder of Debentures is not entitled to any rights of a holder of Common Stock
until such Holder has converted its Debentures to Common Stock, and only to the
extent such Debentures are deemed to have been converted to Common Stock under
this Article 11.

      The "MARKET PRICE CONDITION" shall be satisfied if, at any time after the
date of this Indenture, the last reported sale price of the Common Stock for at
least 20 trading days during the period of 30 consecutive trading days ending on
the last trading day of the Prior Fiscal Quarter is greater than 120% of the
applicable Conversion Price as in effect on the last trading day of the Prior
Fiscal Quarter.

      The "LAST REPORTED SALE PRICE" of the Common Stock on any date means the
closing sale price per share (or if no closing sale price is reported, the
average of the bid and asked prices or, if more than one in either case, the
average of the average bid and the average asked prices) on such date as
reported by The NASDAQ National Market or, if the Common Stock is not reported
by The NASDAQ National Market, as reported in composite transactions for the
principal U.S. securities exchange on which the Common Stock is traded. If the
Common Stock is not reported by The NASDAQ National Market and not listed for
trading on a U.S. national or regional securities exchange on the relevant date,
the "last reported sale price" will be the last quoted bid price
<PAGE>
                                      -68-

for the Common Stock in the over-the-counter market on the relevant date as
reported by the National Quotation Bureau Incorporated or similar organization.
If the Common Stock is not so quoted, the "last reported sale price" will be the
average of the mid-point of the last bid and asked prices for the Common Stock
on the relevant date quoted by each of at least three independent nationally
recognized investment banking firms selected by the Company for this purpose.

      A "TRADING DAY" is a day during which trading in securities generally
occurs on The NASDAQ National Market or, if the Common Stock is not then listed
on The NASDAQ National Market, on the principal other U.S. national or regional
securities exchange on which the Common Stock is then listed or, if the Common
Stock is not then listed on a national or regional securities exchange, on the
principal other market on which the Common Stock is then traded.

      The "TRADING PRICE CONDITION" shall be satisfied if, at any time after the
date the Debentures are originally issued, the Trading Price per $1,000
principal amount of Debentures for any five (5) consecutive trading day period
(the "MEASUREMENT PERIOD"), as determined following a request by a Holder in
accordance with the next succeeding paragraph, for each day of that measurement
period was less than 95% of the product of the last reported sale price of
Common Stock and the conversion rate for such date (i.e. the number of shares of
Common Stock $1,000 principal amount of Debentures are then convertible into)
(the "PARITY VALUE"); provided that if, on the date of any conversion pursuant
to the Trading Price Condition, the last reported sale price of Common Stock is
between 100% and 120% of the then current conversion price of the Debentures,
Holders shall receive, in lieu of Common Stock based on the conversion rate,
Common Stock with a value equal to the principal amount of such Holder's
Debentures plus accrued and unpaid interest and accrued and unpaid Additional
Amounts and Contingent Interest, if any, as of the conversion date (a "PRINCIPAL
VALUE CONVERSION"). The Common Stock delivered upon a principal value conversion
will be valued at the greater of the conversion price on the conversion date and
the last reported sale price on the third trading day after the conversion date.

      In connection with any conversion upon satisfaction of the Trading Price
Condition, the Trustee (or other Conversion Agent appointed by the Company)
shall have no obligation to determine the Trading Price of the Debentures unless
the Company has requested such determination; and the Company shall have no
obligation to make such request unless a Holder provides the Company with
reasonable evidence that the Trading Price for $1,000 principal amount of
Debentures would be less than the Parity Value. At such time, the Company shall
instruct the Trustee or Conversion Agent, as the case may be, to determine the
Trading Price of the Debentures beginning on the next trading day and on each
successive trading day until, and only until, the Trading Price for $1,000
principal amount of Debentures is greater than or equal to the Parity Value.

      A "DIVIDEND PAYMENT PERIOD" shall commence on each date on which the
Company has announced that it will (i) issue a Below Market Issuance, (ii)
distribute a Cash Dividend or an
<PAGE>
                                      -69-

Asset Distribution, which distribution has a per share value as determined in
good faith by the Board of Directors exceeding 10% of the last reported sale
price of Common Stock on the trading day immediately preceding the declaration
date for such distribution or (iii) has commenced a Tender Offer, and end on the
earlier of (a) the close of business on the business day immediately prior to
the ex-dividend date with respect to such distribution or dividend (or in the
case of a Tender Offer, at the close of business on the business day immediately
prior to the expiration of the Tender Offer) and (b) the close of business on
the first business day after the day on which the Company makes a public
announcement that such distribution or dividend will not be issued or that such
Tender Offer has been terminated.

      A Holder may convert a portion of a Debenture equal to $1,000 or any
integral multiple thereof. Provisions of this Indenture that apply to conversion
of all of a Debenture also apply to conversion of a portion of a Debenture.

      If a Debenture is called for redemption pursuant to Article 3, the right
to convert such Debenture shall terminate at the close of business on the second
business day before the Redemption Date for such Debenture (unless the Company
shall default in making the redemption payment then due, in which case the
conversion right shall terminate on the date such Default is cured and such
Debenture is redeemed.

11.02 Conversion Procedure.

      To convert a Debenture, a Holder must satisfy the requirements in
paragraph 8 of the Debentures and (i) complete and manually sign the irrevocable
conversion notice on the back of the Debenture and deliver such notice to the
Conversion Agent, (ii) surrender the Debenture to the Conversion Agent, (iii)
furnish appropriate endorsements and transfer documents if required by the
Registrar or the Conversion Agent, (iv) pay any transfer or other tax, if
required by Section 11.04 and (v) if the Debenture is held in book-entry form,
complete and deliver to the Depositary appropriate instructions pursuant to the
Depositary's book-entry conversion programs. The date on which the Holder
satisfies all of the foregoing requirements is the "CONVERSION DATE". As soon as
practicable after the Conversion Date and in any event within five business
days, the Company shall deliver to the Holder through the Conversion Agent
either (i) a certificate for or (ii) a book-entry notation of the number of
whole shares of Common Stock issuable upon the conversion pursuant to Section
11.05 and cash in lieu of any fractional shares.

      The Person in whose name the Debenture is registered shall be deemed to be
a stockholder of record on the Conversion Date; provided, however, that no
surrender of a Debenture on any date when the stock transfer books of the
Company shall be closed shall be effective to constitute the Person or Persons
entitled to receive the shares of Common Stock upon such conversion as the
record holder or holders of such shares of Common Stock on such date, but such
surrender shall be effective to constitute the Person or Persons entitled to
receive such shares of Common Stock as the record holder or holders thereof for
all purposes at the close of business on the next succeeding day on which such
stock transfer books are open (subject to the provisions of
<PAGE>
                                      -70-

the next paragraph of this Section 11.02); provided, further, that such
conversion shall be at the Conversion Price in effect on the date that such
Debenture shall have been surrendered for conversion, as if the stock transfer
books of the Company had not been closed. Upon conversion of a Debenture, such
Person shall no longer be a Holder of such Debenture.

      In respect of any Debenture presented for conversion, the Company may, at
its option, in lieu of delivering shares of Common Stock, elect to pay the
Holder surrendering such Debenture an amount of cash equal to the average of the
last reported sale price for the Common Stock for the five consecutive trading
days immediately following (a) the date of delivery of the Company's notice of
its election to deliver cash (as described in the next succeeding sentence) if
the Company has not given Notice of Redemption, or (b) the Conversion Date, in
the case of a conversion following a Notice of Redemption with respect to such
Debenture, specifying that the Company intends to deliver cash upon conversion,
in either case multiplied by the number of shares of Common Stock issuable upon
conversion of such Debenture on that date. The Company shall inform Holders of
its election to deliver shares of Common Stock or to pay cash in lieu of the
delivery of such shares by delivering an irrevocable written notice to the
Trustee and the Paying Agent prior to the close of business on the second
business day after the Conversion Date, unless it has already informed Holders
of its election by delivering an irrevocable notice in connection with its
optional redemption of the Debentures as set forth in Section 3.01 hereof. If
the Company delivers only shares of Common Stock upon conversion, such shares
shall be delivered through the Trustee no later than the fifth business day
following the Conversion Date. If the Company elects to satisfy all or a portion
of its obligation to deliver shares upon conversion in cash, the payment,
including any delivery of Common Stock, will be made to Holders surrendering
Debentures no later than the tenth business day following the applicable
Conversion Date; provided that if an Event of Default has occurred and is
continuing, the Company shall not pay cash upon conversion of any Debentures
(other than cash in lieu of fractional shares as set forth below).

      Accrued interest (including Contingent Interest, accrued Tax Original
Issue Discount and Additional Amounts, if any) on a Debenture shall not be
cancelled, extinguished or forfeited but rather shall, except as otherwise set
forth herein, be deemed paid by an applicable portion of the Common Stock issued
upon conversion of such Debenture. Except as set forth in the preceding
sentence, no payment or adjustment will be made for accrued interest (including
Contingent Interest or Additional Amounts, if any), on a converted Debenture or
for dividends or distributions on shares of Common Stock issued upon conversion
of a Debenture (provided that the shares of Common Stock received upon
conversion of Debentures shall continue to accrue Additional Amounts, as
applicable, in accordance with the Registration Rights Agreement and shall be
entitled to receive, at the next Interest Payment Date, any accrued but unpaid
Additional Amounts with respect to the converted Debentures), but if any Holder
surrenders a Debenture for conversion between the record date for the payment of
an installment of interest and the next Interest Payment Date, then,
notwithstanding such conversion, the interest (including Contingent Interest or
Additional Amounts, if any), payable on such Interest Payment Date shall be paid
to the
<PAGE>
                                      -71-

Holder of such Debenture on such Interest Payment Date. In such event, such
Debenture, when surrendered for conversion, must be accompanied by delivery of a
check payable to the Conversion Agent in an amount equal to the interest
(including Contingent Interest or Additional Amounts, if any), payable on such
Interest Payment Date on the portion so converted. If such payment does not
accompany such Debenture, the Debenture shall not be converted; provided,
however, that no such check shall be required if such Debenture has been called
for redemption on a redemption date within the period between and including such
record date and such Interest Payment Date, or if such Debenture is surrendered
for conversion on the Interest Payment Date. If the Company defaults in the
payment of interest (including Contingent Interest or Additional Amounts, if
any), payable on the Interest Payment Date, the Conversion Agent shall repay
such funds to the Holder.

      No fractional shares of Common Stock 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 that shall be issuable
upon conversion shall be computed on the basis of the aggregate principal amount
of the Debentures (or specified portions thereof to the extent permitted hereby)
so surrendered. If any fractional share of Common Stock would be issuable upon
the conversion of any Debenture or Debentures, the Company shall make a payment
in lieu thereof in cash based on the current Market Price of a share of Common
Stock on the Conversion Date.

      Upon surrender of a Debenture that is converted in part, the Company shall
execute, and the Trustee shall authenticate and deliver to the Holder, a new
Debenture equal in principal amount to the unconverted portion of the Debenture
surrendered.

11.03 Adjustments Below Par Value.

      Before taking any action which would cause an adjustment decreasing the
Conversion Price so that the shares of Common Stock issuable upon conversion of
the Debentures would be issued for less than the par value of such Common Stock,
the Company will take all corporate action which may be necessary in order that
the Company may validly and legally issue fully paid and nonassessable shares of
such Common Stock at such adjusted Conversion Price.

11.04 Taxes on Conversion.

      If a Holder converts a Debenture, the Company shall pay any documentary,
stamp or similar issue or transfer tax due on the issue of shares of Common
Stock upon such conversion. However, the Holder shall pay any such tax which is
due because the Holder requests the shares to be issued in a name other than the
Holder's name. The Conversion Agent may refuse to deliver the certificates
representing the Common Stock being issued in a name other than the Holder's
name until the Conversion Agent receives a sum sufficient to pay any tax which
will be due because the shares are to be issued in a name other than the
Holder's name. Nothing herein shall preclude any tax withholding required by law
or regulations.

                                      -72-

11.05 Company to Provide Stock.

      The Company shall, prior to issuance of any Debentures hereunder, and from
time to time as may be necessary, reserve, out of its authorized but unissued
Common Stock a sufficient number of shares of Common Stock to permit the
conversion of all outstanding Debentures into shares of Common Stock. The shares
of Common Stock or other securities issued upon conversion of Debentures bearing
a legend as provided in Section 2.06(f) shall bear a legend substantially in the
following form:

            "THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A
      TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES SECURITIES
      ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND THIS SECURITY MAY NOT
      BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH
      REGISTRATION OR AN APPLICABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS
      OF THE SECURITIES ACT. EACH PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED
      THAT THE SELLER OF THIS SECURITY MAY BE RELYING ON THE EXEMPTION FROM THE
      PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A
      THEREUNDER.

            THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE COMPANY
      THAT (A) THIS SECURITY MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE
      TRANSFERRED, ONLY (I) TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A
      QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE
      SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A,
      (II) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT
      PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE) OR (III) PURSUANT TO AN
      EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF
      CASES (I) THROUGH (III) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS
      OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH
      SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS SECURITY
      FROM THE HOLDER OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE."

      The Company covenants that all shares of Common Stock delivered upon
conversion of the Debentures shall be newly issued shares or treasury shares,
shall be duly authorized, validly issued, fully paid and non-assessable and
shall be free from preemptive rights and free of any lien or adverse claim.
<PAGE>
                                      -73-

      The Company will endeavor promptly to comply with all federal and state
securities laws regulating the offer and delivery of shares of Common Stock upon
conversion of Debentures, if any, and will list or cause to have quoted such
shares of Common Stock on each national securities exchange or in the
over-the-counter market or such other market on which the Common Stock is then
listed or quoted.

11.06 Adjustment of Conversion Price.

      The Conversion Price shall be adjusted from time to time, without
duplication, as follows:

            (a) In case the Company shall pay or make a dividend or other
      distribution on Common Stock in shares of Common Stock to all or
      substantially all holders of shares of Common Stock, then the Conversion
      Price in effect at the opening of business on the day following the date
      fixed for the determination of shareholders entitled to receive such
      dividend or other distribution shall be reduced by multiplying such
      Conversion Price by a fraction the numerator of which shall be the number
      of shares of Common Stock outstanding at the close of business on the date
      fixed for such determination and the denominator of which shall be the sum
      of such number of shares and the total number of shares constituting such
      dividend or other distribution, such reduction to become effective
      immediately after the opening of business on the day following the date
      fixed for such determination. For the purposes of this subparagraph (a),
      the number of shares of Common Stock at any time outstanding shall not
      include shares held in the treasury of the Company (except to the extent
      such dividend or distribution is being made with respect to such shares)
      but shall include shares issuable in respect of scrip certificates issued
      in lieu of fractions of shares of Common Stock.

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

            (c) In case the Company shall issue to all or substantially all
      holders of its Common Stock, rights, warrants or options entitling such
      holders (for a period commencing no earlier than the record date described
      below and expiring not more than 60 days after such record date) to
      subscribe for or purchase shares of Common Stock (or securities
      convertible into Common Stock) at a price per share less than the Market
      Price at the
<PAGE>
                                      -74-

      record date for the determination of stockholders entitled to receive such
      rights, warrants or options (a "BELOW MARKET ISSUANCE"), the Conversion
      Price in effect immediately prior thereto shall be adjusted so that the
      Conversion Price shall equal the price determined by multiplying the
      Conversion Price in effect immediately prior to such record date by a
      fraction, the numerator of which shall be the number of shares of Common
      Stock outstanding on such record date, plus the number of shares that the
      aggregate subscription or purchase price for the total number of shares of
      Common Stock offered by the rights, warrants or options so issued (or the
      aggregate conversion price of the convertible securities offered by such
      rights, warrants or options) would purchase at such Market Price, and the
      denominator of which shall be the number of shares of Common Stock
      outstanding on such record date plus the number of additional shares of
      Common Stock offered by such rights, warrants or options (or into which
      the convertible securities so offered by such rights, warrants or options
      are convertible). Such adjustment shall be made successively whenever any
      such rights, warrants or options are issued, and shall become effective
      immediately after such record date. If at the end of the period during
      which such rights, warrants or options are exercisable not all rights,
      warrants or options shall have been exercised, the adjusted Conversion
      Price shall be immediately readjusted to what it would have been upon
      application of the foregoing adjustment substituting the number of
      additional shares of Common Stock actually issued (or the number of shares
      of Common Stock issuable upon conversion of convertible securities
      actually issued) for the total number of shares of Common Stock offered
      (or the convertible securities offered).

            (d) In case the Company shall distribute to all or substantially all
      holders of Common Stock (i) the Company's equity securities (other than
      Common Stock), (ii) evidences of the Company's indebtedness and/or (iii)
      other assets (including securities, but excluding (1) any rights, warrants
      or options referred to in clause (c) above, (2) any rights or warrants to
      acquire any capital stock of any entity other than the Company, (3) any
      dividends or distributions in connection with the Company's liquidation,
      dissolution or winding-up, (4) any dividends payable solely in cash that
      may from time to time be declared by the Company's Board of Directors and
      (5) any dividends or distributions referred to in clause (a) above) (each
      of (i), (ii) and (iii), an "ASSET DISTRIBUTION"), in which case, the
      Conversion Price shall be adjusted so that the adjusted Conversion Price
      shall equal the number determined by multiplying the Conversion Price in
      effect on the record date with respect to the Asset Distribution by the
      fraction of "A/B," where "A" is equal to the last reported sale price (as
      defined above) of Common Stock on such record date minus the fair market
      value on such record date (as determined in good faith by the Company's
      Board of Directors, whose determination shall be conclusive evidence of
      such fair market value) of the portion of the Asset Distribution
      applicable to one share of Common Stock, and "B" is equal to such last
      reported sale price.

            (e) In case the Company shall distribute or dividend to all or
      substantially all holders of Common Stock, cash (a "CASH Dividend") that
      when combined with all other
<PAGE>
                                      -75-

      Cash Dividends paid within the calendar year during which such Cash
      Dividend is paid exceeds $4.00 per share of Common Stock (appropriately
      adjusted from time to time for any stock dividends on or subdivisions or
      combinations of or other similar events with respect to Common Stock) (the
      amount of such excess, the "EXCESS DIVIDEND"), in which case, the
      Conversion Price shall be reduced so that the adjusted Conversion Price
      shall equal the number determined by multiplying the Conversion Price in
      effect on the record date with respect to the Cash Dividend by the
      fraction of "B/A," where "A" is equal to the last reported sale price of
      Common Stock on such record date, and "B" is equal to such last reported
      sale price minus the amount of Excess Dividend applicable to one share of
      then outstanding Common Stock.

            (f) In case a tender or exchange offer (a "TENDER OFFER") made by
      the Company or any subsidiary of the Company for all or any portion of the
      Common Stock shall expire and such Tender Offer (as amended as of the
      expiration thereof) shall require the payment to common stockholders of
      consideration per share of Common Stock having a cash and fair market
      value and any other consideration included in such payment per share of
      Common Stock (as determined by the Board of Directors, whose determination
      shall be conclusive and described in a resolution of the Board of
      Directors) that as of the last time (the "EXPIRATION TIME") tenders or
      exchanges may be made pursuant to such Tender Offer (as it may be amended)
      exceeds the first reported sale price per share of Common Stock on the
      trading day next succeeding the Expiration Time, the Conversion Price
      shall be decreased so that the same shall equal the price determined by
      multiplying the Conversion Price in effect immediately prior to the
      Expiration Time by a fraction,

                    (i) the numerator of which shall be the number of shares of
            Common Stock outstanding (including any tendered or exchanged
            shares) at the Expiration Time multiplied by the Closing Price of a
            share of Common Stock on the trading day next succeeding the
            Expiration Time, and

                    (ii)the denominator of which shall be the sum of (x) the
            fair market value (determined as aforesaid) of the aggregate
            consideration payable to stockholders based on the acceptance (up to
            any maximum specified in the terms of the tender or exchange offer)
            of all shares validly tendered or exchanged and not withdrawn as of
            the Expiration Time (the shares deemed so accepted up to any such
            maximum, being referred to as the "PURCHASED SHARES") and (y) the
            product of the number of shares of Common Stock outstanding (less
            any Purchased Shares) at the Expiration Time and the last reported
            sale price of a share of Common Stock on the trading day next
            succeeding the Expiration Time,

      such adjustment to become effective immediately prior to the opening of
       business on the day following the Expiration Time. If the Company is
       obligated to purchase shares pursuant to any such Tender Offer, but the
       Company is permanently prevented by applicable
<PAGE>
                                      -76-

      law from effecting any such purchases or all such purchases are rescinded,
      the Conversion Price shall again be adjusted to be the Conversion Price
      that would then be in effect if such Tender Offer had not been made.

      If an adjustment is required to be made as set forth in Section 11.06(f)
above, such adjustment shall be calculated based upon the amount by which the
aggregate consideration paid for Common Stock acquired in the Tender Offer
exceeds the value of such shares based on the first reported sale price of
Common Stock on the trading day next succeeding the Expiration Time.

11.07 No Adjustment.

      No adjustment in the Conversion Price shall be required unless the
adjustment would require an increase or decrease of at least 1% in the
Conversion Price then in effect; provided, however, that any adjustment which by
reason of this Section 11.07 is not required to be made shall be carried forward
and taken into account in any subsequent adjustment. All calculations under this
Article 11 by the Company shall be made to the nearest cent or to the nearest
one-hundredth of a share, as the case may be.

      With respect to Sections 11.06(d) and (e) hereof, no adjustment to the
Conversion Price shall be made if the Company provides that Holders of
Debentures will participate in the Asset Distribution or the Cash Dividend, as
applicable, on an as-converted basis without conversion. Furthermore, if the
numerator of the fraction described in Sections 11.06(d) and (e) hereof is less
than $1.00 (including a negative amount) then in lieu of any adjustment of the
Conversion Price, the Company shall make adequate provision so that each Holder
of Debentures shall have the right to receive upon conversion, in addition to
the shares of Common Stock issuable upon such conversion, the distribution or
dividend such Holder would have received had such Holder converted such
Debentures immediately prior to the record date for such distribution or
dividend. In the case where this Indenture provides that a Conversion Price
adjustment is effective upon the record date for a distribution or dividend, if
the distribution or dividend is not so paid or made, the Conversion Price shall
again be adjusted to be the Conversion Price that would then be in effect if
such distribution or dividend had not been declared.

11.08 Equivalent Adjustments.

      If, as a result of an adjustment made pursuant to Section 11.06 above, the
holder of any Debenture thereafter surrendered for conversion shall become
entitled to receive any shares of capital stock of the Company other than shares
of its Common Stock, thereafter the Conversion Price of such other shares so
receivable upon conversion of any Debentures shall be subject to adjustment from
time to time in a manner and on terms as nearly equivalent as practicable to the
provisions with respect to Common Stock contained in this Article 11.
<PAGE>
                                      -77-

11.09 Notice of Adjustment.

      Whenever the Conversion Price is adjusted, or Holders become entitled to
other securities or due bills, the Company shall promptly mail to Holders a
notice of the adjustment and file with the Trustee an Officers' Certificate
briefly stating the facts requiring the adjustment and the manner of computing
it. The certificate shall be conclusive evidence of the correctness of such
adjustment and the Trustee may conclusively assume that, unless and until such
certificate is received by it, no such adjustment is required.

11.10 Notice of Certain Transactions.

      The Company shall give notice to the Holders of record of the Debentures
of the pending occurrence of each Below Market Issuance, Cash Dividend and Asset
Distribution not less than twenty business days prior to the ex-dividend date
for such distribution and notice to the Holders of record of the Debentures of
the occurrence of each Change of Control within twenty business days after the
Company obtains knowledge of such occurrence of a Change of Control.

      The Company shall cause any such notice to be filed with the Trustee and
the Conversion Agent and to be mailed to each Holder of Debentures at its
address appearing on the list provided for in Section 2.05, as promptly as
possible but in any event at least ten days prior to the applicable date
hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of such transaction, or, if a record is not to be taken,
the date as of which the holders of Common Stock are to be determined, or (y)
the date on which such transaction is expected to become effective or occur, and
the date as of which it is expected that holders of Common Stock of record shall
be entitled to exchange their Common Stock for securities or other property
deliverable upon such transaction. Notwithstanding anything in this paragraph to
the contrary, the Company shall not be obligated under this Indenture to provide
notice to Holders of a Change of Control, other than as set forth in the
preceding paragraph.

11.11 Effect of Reclassification, Consolidation, Merger, Share Exchange or
      Sale on Conversion Privilege.

      If any of the following shall occur, namely (i) any reclassification or
change of outstanding shares of Common Stock (other than a change in par value,
or from par value to no par value, or from no par value to par value, or as a
result of a subdivision or combination); (ii) any consolidation, combination,
merger or share exchange to which the Company is a party other than a merger in
which the Company is the continuing corporation and that does not result in any
reclassification of, or change (other than a change in name, or par value, or
from par value to no par value, or from no par value to par value, or as a
result of a subdivision or combination) in, outstanding shares of Common Stock;
or (iii) any sale or conveyance of all or substantially all of the assets of the
Company, then the Company, or such successor or purchasing corporation, as the
case may be, shall, as a condition precedent to such reclassification, change,
consolidation, combination, merger, share exchange, sale or conveyance, execute
and deliver to the Trustee a
<PAGE>
                                      -78-

supplemental indenture providing that the Holder of each Debenture then
outstanding shall have the right to convert such Debenture into the kind and
amount of shares of capital stock and other securities and property (including
cash) ("ACQUIROR SECURITIES") receivable upon such reclassification, change,
consolidation, combination, merger, share exchange, sale or conveyance by a
holder of the number of shares of Common Stock deliverable upon conversion of
such Debenture immediately prior to the record date of such reclassification,
change, consolidation, combination, merger, share exchange, sale or conveyance.
Such supplemental indenture shall provide for adjustments of the Conversion
Price that shall be as nearly equivalent as may be practicable to the
adjustments of the Conversion Price provided for in this Article 11. If, in the
case of any such consolidation, combination, merger, share exchange, sale or
conveyance, the stock or other securities and property (including cash)
receivable thereupon by a holder of Common Stock includes shares of capital
stock or other securities and property of a corporation other than the successor
or purchasing corporation, as the case may be, in such consolidation,
combination, merger, share exchange, 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 provision of this Section 11.11 shall
similarly apply to successive consolidations, combination mergers, share
exchanges, sales or conveyances. Notwithstanding the foregoing, a distribution
by the Company to all or substantially all holders of its Common Stock for which
an adjustment to the Conversion Price or provision for conversion of the
Debentures may be made pursuant to Section 11.06 shall not be deemed to be a
sale or conveyance of all or substantially all of the assets of the Company for
purposes of this Section 11.11.

      In the event the Company shall execute a supplemental indenture pursuant
to this Section 11.11, the Company shall promptly file with the Trustee an
Opinion of Counsel stating that such supplemental indenture is authorized or
permitted by this Indenture and an Officers' Certificate briefly stating the
reasons therefor, the kind or amount of shares of stock or securities or
property (including cash) receivable by Holders of the Debentures upon the
conversion of their Debentures after any such reclassification, change,
consolidation, combination, merger, share exchange, sale or conveyance, any
adjustment to be made with respect thereto and that all conditions precedent
have been complied with.

11.12 Trustee's Disclaimer.

      The Trustee has no duty to determine when an adjustment under this Article
11 should be made, how it should be made or what such adjustment should be made,
but may accept as conclusive evidence of the correctness of any such adjustment,
and shall be protected in relying upon, the Officers' Certificate with respect
thereto which the Company is obligated to file with the Trustee pursuant to
Section 11.09. The Trustee shall not be accountable for and makes no
representation as to the validity or value of any securities or assets issued
upon conversion of Debentures, and the Trustee shall not be responsible for the
Company's failure to comply with
<PAGE>
                                      -79-

any provisions of this Article 11. Each Conversion Agent (other than the Company
or an Affiliate of the Company) shall have the same protection under this
Section 11.12 as the Trustee.

      The Trustee shall not be under any responsibility to determine the
correctness of any provisions contained in any supplemental indenture executed
pursuant to Section 11.11, but may accept as conclusive evidence of the
correctness thereof, and shall be protected in relying upon, the Officers'
Certificate with respect thereto, which the Company is obligated to file with
the Trustee pursuant to Section 11.11.

11.13 Voluntary Reduction.

      The Company may, from time to time, to the extent permitted by law and The
NASDAQ Stock Market Marketplace Rules, reduce the Conversion Price by any amount
for any period of at least 20 business days, in which case the Company shall
give at least fifteen (15) days' notice of such reduction. In particular, the
Company may, at its option, make such reduction in the Conversion Price, in
addition to those set forth in Section 11.06, as it deems advisable to avoid or
diminish any income tax to holders of Common Stock resulting from any dividend
or distribution of stock (or rights to acquire stock) or from any event treated
as such for tax purposes or for any other reasons.

11.14 Simultaneous Adjustments.

      In the event that this Article 11 requires adjustments to the Conversion
Price under more than one of the subsections of Section 11.06, and the record
dates for the distributions giving rise to such adjustments shall occur on the
same date, or if more than one event requiring adjustment pursuant to Section
11.06 shall occur before completing the determination for the Conversion Price
for the first event requiring such adjustment, then in each case, such
adjustments shall be made in such order as determined by the Board of Directors
(whose determination shall, if made in good faith, be conclusive) as shall
preserve for Holders the Conversion Price protection provided in Section 11.06.

                            [BACK OF DEBENTURE]

        5.0% CONTINGENT CONVERTIBLE SUBORDINATED DEBENTURE DUE 2033

      Capitalized terms used herein shall have the meanings assigned to them in
the Indenture referred to below unless otherwise indicated.

      1. Interest. Grey Global Group Inc., a Delaware corporation (the
"COMPANY"), promises to pay interest on the principal amount of this Debenture
at 5.0% per annum from October 28, 2003 until maturity and shall pay the
Additional Amounts, if any, payable pursuant to Section 3 of the Registration
Rights Agreement referred to below. The Company will pay interest and, if
applicable, Contingent Interest and Additional Amounts, if any, semi-annually in
arrears on April 15 and October 15 of each year, or if any such day is not a
business day, on the next succeeding business day (each an "INTEREST PAYMENT
DATE"). Interest on the Debentures will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from the date of
issuance; provided that the first Interest Payment Date shall be April 15, 2004.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months.

      Subject to the accrual, record date and payment provisions above,
contingent interest ("CONTINGENT INTEREST") will accrue during any six-month
interest period (a "CONTINGENT INTEREST PERIOD") beginning with the six-month
interest period commencing on October 15, 2013, if the average Trading Price of
the Debentures for the five trading days (as defined in the Indenture) ending on
the third trading day immediately preceding the first day of the applicable
Contingent Interest Period equals $1,200 or more per $1,000 principal amount of
Debentures. During any period in which Contingent Interest accrues, it will be
payable per $1,000 principal amount of Debentures at a rate per annum equal to
0.50% of such average Trading Price. The Company will pay Contingent Interest,
if any, in the same manner as it will pay interest as described above. Upon
determination that Contingent Interest on the Debentures will accrue during any
relevant six-month period, on or prior to the start of such six-month period,
the Company shall issue a press release announcing the payment of such
Contingent Interest and shall notify the Trustee in writing.

      So long as the Company is not in default in the payment of interest on the
Debentures, the Company shall have the right to extend the interest payment
period (such extended period, an "EXTENSION PERIOD"), including the payment of
Contingent Interest, from time to time for a period not exceeding 10 consecutive
semi-annual interest periods, provided that such Extension Period shall
terminate upon the occurrence of a Default or Event of Default, and provided
further that no Extension Period shall extend beyond October 15, 2033. No
interest shall be due and payable during an Extension Period, except at the end
thereof, provided that interest (including Compounded Interest) shall accrue.
During any Extension Period, the Company shall not (i) declare or pay any
dividends on, or redeem, purchase, acquire or make a distribution or liquidation
payment with respect to, any of the Company's common stock or preferred stock or
make any guarantee payments with respect thereto (provided that the foregoing
will not apply (a) to repur-

                                      A-3
<PAGE>
chases, redemptions or other acquisitions of shares of the Company's capital
stock in connection with any employment contract, benefit plan or other similar
arrangement with or for the benefit of employees, officers, directors or
consultants, which contract, plan or arrangement is approved by the Company's
Board of Directors, (b) as a result of an exchange or conversion of any class or
series of the Company's capital stock for any other class or series of the
Company's capital stock, (c) to the purchase of fractional interests in shares
of the Company's capital stock pursuant to the conversion or exchange provisions
of such capital stock or the security being converted or exchanged or (d) to
stock dividends or other stock distributions (including rights, warrants or
options to purchase capital stock) paid by the Company) or (ii) make any payment
of principal, interest or premium, if any, on or repay, repurchase or redeem any
of the Company's debt securities that rank in right of payment pari passu with,
or junior to, the Debentures. Prior to the termination of any such Extension
Period, the Company may further extend the interest payment period; provided
that such Extension Period together with all such previous and further
extensions thereof may not exceed 10 consecutive semi-annual interest payment
periods or extend beyond October 15, 2033. On the first Interest Payment Date
occurring on or after the end of each Extension Period, the Company shall pay to
the Holders of Debentures of record on the record date for such Interest Payment
Date (regardless of who the Holders of record may have been on other dates
during the Extension Period) all accrued and unpaid interest (including
Contingent Interest, if any) on the Debentures, together with Compounded
Interest. Upon the termination of any Extension Period and the payment of all
amounts then due, the Company may commence a new Extension Period, subject to
the above requirements. The Company may also prepay at any time all or any
portion of the interest accrued during an Extension Period. Consequently, there
could be multiple Extension Periods of varying lengths throughout the term of
the Debentures, not to exceed 10 consecutive semi-annual interest payment
periods; provided, that no such period may extend beyond October 15, 2033.

      If at any time other than an Interest Payment Date the Company elects to
prepay all or a portion of the interest accrued during an Extension Period, the
Company will (a) if the debentures are listed on a national securities exchange
or quoted on The NASDAQ National Market, make payment of such deferred interest
in accordance with the regulations of the principal exchange or market on which
the Debentures are listed or quoted, if any, or (b) deliver an irrevocable
notice to the Holders of the Debentures notifying such holders of the prepayment
date, which date shall be not less than 30 days nor more than 60 days after the
delivery of such notice. The notice shall state, among other things, the amount
of deferred interest to be paid on such prepayment date and shall establish a
special record date for the prepayment of such deferred interest (the "SPECIAL
RECORD DATE"). The Special Record Date shall be no less than 10 days nor more
than 15 days prior to the prepayment date. The Company will pay such deferred
interest to the Holders of Debentures of record on the Special Record Date
(regardless of who the Holders of record may have been on other dates during the
Extension Period).

      The Company shall give notice to the Trustee of its election of an
Extension Period ten business days prior to the earlier of (i) the next
succeeding Interest Payment Date or (ii) the date the Company is required to
give notice to The NASDAQ National Market (if the Debentures are

                                      A-4
<PAGE>
then listed thereon) or other applicable self-regulatory organization or to
Holders of the Debentures of the record or payment date of such related interest
payment.

      2. METHOD OF PAYMENT. The Company will pay interest on the Debentures
(including Contingent Interest, if any) (except defaulted interest) and
Additional Amounts, if any, to the Persons who are registered Holders of
Debentures at the close of business on the April 1 or October 1 next preceding
the Interest Payment Date, even if such Debentures are canceled after such
record date and on or before such Interest Payment Date, except as provided in
Section 2.12 of the Indenture with respect to defaulted interest. The Debentures
will be payable as to principal and Additional Amounts, if any, and interest
(including Contingent Interest, if any) at the office or agency of the Company
maintained for such purpose, or, at the option of the Company, payment of
interest (including Contingent Interest, if any) and Additional Amounts, if any,
may be made (i) by check mailed to the Holders at their addresses set forth in
the register of Holders, or (ii) to a Holder of record with an aggregate
principal amount of Debentures in excess of $2.0 million, if such Holder so
elects in writing, by wire transfer in immediately available funds to an account
in the United States; provided such Holder shall have provided wire transfer
instructions to the Company or the Paying Agent at least fifteen (15) business
days prior to the applicable payment date. Such payment shall be in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts.

      3.    AGENT AND REGISTRAR.  Initially, American Stock Transfer &
Trust Company, the Trustee under the Indenture, will act as Paying Agent
and Registrar.  The Company may change any Paying Agent or Registrar
without notice to any Holder.  The Company or any of its subsidiaries may
act in any such capacity.

      4. INDENTURE. The Company issued the Debentures under an Indenture dated
as of October 28, 2003 ("INDENTURE"), between the Company and the Trustee. 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 of 1939, as
amended. The Debentures are subject to all such terms, and Holders are referred
to the Indenture and such Act for a statement of such terms. To the extent any
provision of this Debenture conflicts with the express provisions of the
Indenture, the provisions of the Indenture shall govern and be controlling.

      5. OPTIONAL REDEMPTION. No sinking fund is provided for in the Debentures.
Beginning on October 15, 2013 and during the periods thereafter to maturity, the
Company may redeem the Debentures, in whole or in part, from time to time, at a
price equal to 100% of the principal amount of the Debentures plus accrued but
unpaid interest (including Compounded Interest, Contingent Interest and
Additional Amounts, if any) up to but not including the Redemption Date.

      The Company will pay interest to a Person other than the Holder of record
on the record date if it redeems such Holder's Debentures on a date that is
after the record date and prior to the corresponding Interest Payment Date. In
this instance, the Company will pay interest accrued

                                      A-5
<PAGE>
and unpaid on the Debentures being redeemed, to but not including the Redemption
Date to the same Person to whom the Company will pay the principal of such
Debentures.

      6. PURCHASE AT THE OPTION OF THE HOLDER UPON A CHANGE OF CONTROL. At the
option of the Holder and subject to the terms and conditions of the Indenture,
the Company shall become obligated to purchase the Debentures held by such
Holder after the occurrence of a Change of Control of the Company for a Change
of Control Repurchase Price equal to 100% of the principal amount thereof plus
accrued but unpaid interest (including Contingent Interest and Additional
Amounts, if any), thereon, up to but not including the Change of Control
Repurchase Date (provided that, if the Change of Control Repurchase Date is on
or after an interest record date but on or prior to the related Interest Payment
Date, accrued but unpaid interest will be payable to the Holders in whose names
the Debentures are registered at the close of business on the relevant record
date). Holders have the right to withdraw any Holder Change of Control
Acceptance Notice by delivering to the Paying Agent a written notice of
withdrawal in accordance with the provisions of the Indenture.

      Notwithstanding anything set forth above, the Company may elect (which
election shall be irrevocable) to pay the Change of Control Repurchase Price in
Common Stock, Acquiror Securities that are publicly traded securities, or a
combination of cash, shares of Common Stock and such publicly traded Acquiror
Securities. In such event, the number of shares of Common Stock or Acquiror
Securities that are publicly traded a Holder will receive will equal the portion
of the Change of Control Repurchase Price payable in such shares divided by 95%
of the average of the last reported sale price of the Common Stock or Acquiror
Securities for the five trading days immediately preceding and including the
third trading day prior to the Change of Control Repurchase Date. All shares of
Common Stock issued pursuant to the previous sentence must be issued out of the
Company's authorized but unissued Common Stock or treasury stock and will, upon
issue, be duly and validly issued and fully paid and non-assessable.

      If cash or shares of Common Stock or Acquiror Securities sufficient to pay
the Change of Control Repurchase Price on all Debentures or portions thereof to
be purchased as of the Change of Control Repurchase Date are held by the Paying
Agent on the business day prior to the Change of Control Repurchase Date,
interest (including Contingent Interest and Additional Amounts, if any), shall
cease to accrue on such Debentures (or portions thereof) as of such Change of
Control Repurchase Date, (whether or not book-entry transfer of the Debentures
has been made or the Debentures have been delivered to the Paying Agent) and the
Holder thereof shall have no other rights as such other than the right to
receive Change of Control Repurchase Price upon surrender of such Debenture.

      7. NOTICE OF REDEMPTION. Notice of redemption of Debentures at the option
of the Company will be mailed at least 30 days but not more than 60 days before
the Redemption Date to each Holder of Debentures to be redeemed at the Holder's
registered address. If money sufficient to pay the Redemption Price of all
Debentures (or portions thereof) to be redeemed on the Redemption Date is
deposited with the Paying Agent prior to or on the Redemption Date, immediately
after such Redemption Date, interest (including Contingent Interest and
Additional

                                      A-6
<PAGE>
Amounts, if any) shall cease to accrue on such Debentures or portions thereof.
Debentures in denominations larger than $1,000 of principal amount may be
redeemed in part but only in integral multiples of $1,000 of principal amount.

      8. Conversion. Subject to the provisions of Article 11 of the Indenture, a
Holder of a Debenture may convert such Debenture into shares of Common Stock of
the Company if any of the conditions specified in paragraphs (a) through (e) of
Section 11.01 of the Indenture is satisfied; provided, however, that if such
Debenture is called for redemption, the conversion right will terminate at the
close of business on the second business day immediately preceding the
Redemption Date of such Debenture (unless the Company shall default in making
the redemption payment when due, in which case the conversion right shall
terminate at the close of business on the date such Default is cured and such
Debenture is redeemed). The initial conversion price is $961.20 per share,
subject to adjustment under certain circumstances as described in the Indenture
(the "CONVERSION PRICE"). The number of shares issuable upon conversion of a
Debenture is determined by dividing the principal amount of Debentures converted
by the Conversion Price in effect on the conversion date. In the event of a
conversion of a Debenture, the Company has the option, in lieu of delivering
shares of Common Stock, to pay the Holder surrendering such Debenture an amount
of cash determined in accordance with Section 11.02 of the Indenture. Upon
conversion, no adjustment for interest (including Contingent Interest and
Additional Amounts, if any), or dividends will be made. No fractional shares
will be issued upon conversion; in lieu thereof, an amount will be paid in cash
based upon the current Market Price (as defined in the Indenture) of the Common
Stock on the last trading day prior to the date of conversion.

      To convert a Debenture, a Holder must (a) complete and sign the
irrevocable conversion notice set forth below (copies of which may also be
obtained from the Conversion Agent) and deliver such notice to the Conversion
Agent, (b) surrender the Debentures by delivering them to the Conversion Agent,
at the office or agency maintained for such purpose in the Borough of Manhattan,
The City of New York, (c) furnish appropriate endorsements and transfer
documents if required by the Registrar or the Conversion Agent, (d) pay any
transfer or similar tax, if required and (e) if the Debenture is held in
book-entry form, complete and deliver to the Depositary appropriate instructions
pursuant to the Depositary's book-entry conversion programs. Upon satisfaction
of such requirements, the Conversion Agent shall, on behalf of such Holder,
immediately convert such Debentures into Common Stock (unless the Company has
elected to pay cash in lieu of delivering shares of Common Stock). If a Holder
surrenders a Debenture for conversion between the record date for the payment of
an installment of interest and the related Interest Payment Date, the Debenture
must be accompanied by payment of an amount equal to the interest (including
Contingent Interest and Additional Amounts, if any), payable on such Interest
Payment Date on the principal amount of the Debenture or portion thereof then
converted; provided, however, that no such payment shall be required if such
Debenture has been called for redemption on a Redemption Date within the period
between and including such record date and such Interest Payment Date, or if
such Debenture is surrendered for conversion on the Interest Payment Date. A
Holder may convert a portion of a Debenture equal to $1,000 or any integral
multiple thereof.

                                      A-7
<PAGE>
      A Debenture in respect of which a Holder has delivered a Holder Change of
Control Acceptance Notice exercising the option of such Holder to require the
Company to repurchase such Debenture as provided in Section 3.11 of the
Indenture may be converted only if such notice of exercise is withdrawn in
accordance with the terms of the Indenture.

      9. Denominations, Transfer, Exchange. The Debentures are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000. The transfer of Debentures may be registered and Debentures may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company need not
exchange or register the transfer of any Debenture or portion of a Debenture
selected for redemption, except for the unredeemed portion of any Debenture
being redeemed in part. Also, the Company need not exchange or register the
transfer of any Debentures for a period of 15 days before a selection of
Debentures to be redeemed or during the period between a record date and the
succeeding Interest Payment Date.

      10. Persons Deemed Owners. The registered Holder of a Debenture may be
treated as its owner for all purposes.

      11. Amendment, Supplement and Waiver. Subject to certain exceptions, the
Indenture or the Debentures may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Debentures voting as a single class, and any existing default or compliance with
any provision of the Indenture or the Debentures may be waived with the consent
of the Holders of a majority in principal amount of the then outstanding
Debentures voting as a single class, except a default in the payment of
principal or interest (unless such default has been cured and a sum sufficient
to pay all matured installments of interest and principal otherwise than by
acceleration has been deposited with the Trustee). Without the consent of any
Holder of a Debenture, the Indenture or the Debentures may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Debentures in addition to or in place of certificated Debentures,
to provide for the assumption of the Company's obligations to Holders of the
Debentures in case of a merger or consolidation, to make any change that would
provide any additional rights or benefits to the Holders of the Debentures or
that does not adversely affect the rights under the Indenture of any such Holder
and to comply with the requirements of the Trust Indenture Act.

      12. Defaults and Remedies. The following are "EVENTS OF DEFAULT" in
respect of the Debentures: (i) failure for 30 days to pay interest on the
Debentures when due, whether or not such payment is prohibited by the
subordination provisions of the Indenture; provided that a valid extension of
the interest payment period by the Company during an Extension Period pursuant
to the Indenture shall not constitute a default in the payment of interest for
this purpose; (ii) failure to pay principal on the debentures when due whether
at maturity, upon redemption, by declaration or otherwise, whether or not such
payment is prohibited by the subordination provisions of the Indenture; (iii)
failure to observe or perform any covenant contained in Article 4 of

                                      A-8
<PAGE>
the Indenture for 90 days after written notice to the Company of such failure
from the Trustee or the Holders of at least 25% in principal amount of the
outstanding Debentures; (iv) the Company's failure to comply with the provisions
of Section 3.11 (Purchase of Debentures at Option of the Holder upon a Change of
Control) or Section 5.01 (Mergers and Sales of Assets by the Company); (v) a
default in the Company's indebtedness with an aggregate amount outstanding in
excess of $25.0 million (a) resulting from the failure to pay principal at
maturity or (b) as a result of which the maturity of such indebtedness has been
accelerated prior to its Stated Maturity; (vi) the Company's failure to pay
final judgments aggregating in excess of $25.0 million, which judgments are not
paid, discharged or stayed for a period of not less than 60 days; or (vii)
certain events in bankruptcy, insolvency or reorganization of the Company. If
any Event of Default occurs and is continuing, the Trustee or the Holders of at
least 25% in principal amount of the then outstanding Debentures may declare all
the Debentures to be due and payable. Notwithstanding the foregoing, in the case
of an Event of Default arising from certain events of bankruptcy or insolvency,
all outstanding Debentures will become due and payable without further action or
notice. Holders may not enforce the Indenture or the Debentures except as
provided in the Indenture. Subject to certain limitations, Holders of a majority
in principal amount of the then outstanding Debentures may direct the Trustee in
its exercise of any trust or power. The Trustee may withhold from Holders of the
Debentures notice of any continuing Default or Event of Default (except a
Default or Event of Default relating to the payment of principal or interest) if
it determines that withholding notice is in their interest. The Holders of a
majority in aggregate principal amount of the Debentures then outstanding by
notice to the Trustee may on behalf of the Holders of all of the Debentures
waive any existing Default or Event of Default and its consequences under the
Indenture except a continuing Default or Event of Default in the payment of
interest on and Additional Amounts, if any, or the principal of, the Debentures
(unless such Default has been cured and a sum sufficient to pay all matured
installments of interest and principal otherwise than by acceleration has been
deposited with the Trustee). The Company is required to deliver to the Trustee
annually a statement regarding compliance with the Indenture, and the Company is
required upon becoming aware of any Default or Event of Default, to deliver to
the Trustee a statement specifying such Default or Event of Default.

      13. Tax Treatment of Debentures. The Company and the Holders and any
beneficial holder of a Debenture, by purchasing the Debentures, agree that (i)
the Debentures are contingent payment debt instruments as defined in Treasury
Regulations Section 1.1275-4(b), (ii) each Holder and any beneficial holder of a
Debenture shall be bound by the Company's application of the Treasury
Regulations to the Debentures, including the Company's determination that the
rate at which interest will be deemed to accrue on the Debentures for United
States federal income tax purposes will be 9.40% compounded semi-annually, which
is the rate comparable to the rate at which the Company would borrow on a
noncontingent, nonconvertible basis with terms and conditions otherwise
comparable to the Debentures, (iii) each Holder and any beneficial holder of a
Debenture shall use the projected payment schedule with respect to the
Debentures determined by the Company, as required by Treasury Regulations
Section 1.1275-4(b)(4)(iv), to determine its interest accruals and adjustments
as provided in Treasury Regulations Section 1.1275-4(b), and (iv) the Company
and each Holder and any beneficial holder of a Debenture will not take any
position on a tax return inconsistent with (i), (ii), or (iii), unless re-

                                      A-9
<PAGE>
quired by applicable law. A Holder of Debentures may obtain the issue price,
amount of original issue discount, issue date, yield to maturity, comparable
yield and projected payment schedule for the Debentures by submitting a written
request for such information to the Company at the following address: Grey
Global Group Inc., 777 Third Avenue, New York, New York 10017; Attention:
Corporate Secretary.

      14. Subordination. The indebtedness evidenced by this Debenture is, to the
extent and in the manner provided in the Indenture (including, without
limitation, Article 10 thereof), subordinated and subject in right of payment to
the prior payment in full in cash or cash equivalents of all amounts then due on
all Senior Debt (whether outstanding on the date hereof or hereafter created,
incurred, assumed or guaranteed) of the Company, and this Debenture is issued
subject to such provisions of the Indenture with respect thereto. Subject to
certain exceptions, the Company may not make any payments of principal, premium,
if any, or interest on this Debenture if an event of default has occurred and is
continuing in any payment with respect to Senior Debt. During the continuance of
any other event of default with respect to Designated Senior Debt, pursuant to
which maturity thereof may be accelerated, the holders of such Designated Senior
Debt may, under certain circumstances, prohibit the Company from making payments
on the Debentures, until such event of default is cured or waived. Each Holder
of this Debenture, by accepting the same, (a) agrees to and shall be bound by
such provisions, (b) authorizes and directs the Trustee on such Holder's behalf
to take such action as may be necessary or appropriate to effectuate the
subordination so provided and (c) appoints the Trustee such Holder's
attorney-in-fact for any and all such purposes.

      15. Trustee Dealings with Company. The Trustee, 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.

      16. No Recourse Against Others. None of the Company's, or of any successor
entity's direct or indirect stockholders, employees, officers or directors, as
such, past, present or future, shall have any personal liability in respect of
the Company's obligations under the Indenture or this Debenture solely by reason
of his or its status as such stockholder, employee, officer or director. Each
Holder by accepting this Debenture waives and releases all such liability. The
waiver and release are part of the consideration for issuance of the Debentures.

      17.   Authentication.  This Debenture shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating
agent.

      18. Abbreviations. Customary abbreviations may be used in the name of a
Holder 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).

      [19. Additional Rights of Holders of Restricted Global Debentures and
Restricted Definitive Debentures. In addition to the rights provided to Holders
of Debentures under the Indenture, Holders of Restricted Global Debentures and
Restricted Definitive Debentures shall have all the rights set forth in the
Registration Rights Agreement dated as of October 28, 2003, between the Company
and the parties named on the signature pages thereof (the "REGISTRATION RIGHTS
AGREEMENT").]

      20. CUSIP Numbers. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Debentures and the Trustee may use CUSIP
numbers in notices of redemption as a convenience to Holders. No representation
is made as to the accuracy of such numbers either as printed on the Debentures
or as contained in any notice of redemption and reliance may be placed only on
the other identification numbers placed thereon.

      The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture and/or the Registration Rights Agreement.
Requests may be made to:

      RE: 5.0% CONTINGENT CONVERTIBLE SUBORDINATED DEBENTURES DUE 2033

Dear Sirs:

      Reference is hereby made to the Indenture, dated as of October 28, 2003
(the "INDENTURE"), between Grey Global Group Inc., as issuer (the "COMPANY"),
and American Stock Transfer & Trust Company, a trust company organized under the
laws of the State of New York, as trustee. Capitalized terms used but not
defined herein shall have the meanings given to them in the Indenture.
______________ (the "TRANSFEROR") owns and proposes to transfer the Debenture[s]
or interest in such Debenture[s] specified in Annex A hereto, in the principal
amount of $___________ in such Debenture[s] or interests (the "TRANSFER"), to
__________ (the "TRANSFEREE"), as further specified in Annex A hereto. In
connection with the Transfer, the Transferor hereby certifies that:

[CHECK ALL THAT APPLY]

[ ]   1.    Check if Transferee will take delivery of a beneficial
            interest in the 144A Global Debenture or a Definitive
            Debenture Pursuant to Rule 144A.  The Transfer is being
            effected pursuant to and in accordance with Rule 144A under
            the United States Securities Act of 1933, as amended (the
            "SECURITIES ACT"), and, accordingly, the Transferor hereby
            further certifies that the beneficial interest or Definitive
            Debenture is being transferred to a person that the Transferor
            reasonably believed and believes is purchasing the beneficial
            interest or Definitive Debenture for its own account, or for
            one or more accounts with respect to which such person
            exercises sole investment discretion, and such person and each
            such account is a "qualified institutional buyer" within the
            meaning of Rule 144A in a transaction meeting the requirements
            of Rule 144A and such Transfer is in compliance with any

      RE: 5.0% CONTINGENT CONVERTIBLE SUBORDINATED DEBENTURES DUE 2033

Dear Sirs:

      Reference is hereby made to the Indenture, dated as of October 28, 2003
(the "INDENTURE"), between Grey Global Group Inc., as issuer (the "COMPANY"),
and American Stock Transfer & Trust Company, a trust company organized under the
laws of the State of New York, as trustee. Capitalized terms used but not
defined herein shall have the meanings given to them in the Indenture.

      In connection with our proposed purchase of $____________ aggregate
principal amount of: (a) a beneficial interest in a Global Debenture, or (b) a
Definitive Debenture, we confirm that:

      1. We understand that any subsequent transfer of the Debentures or any
interest therein is subject to certain restrictions and conditions set forth in
the Indenture and the undersigned agrees to be bound by, and not to resell,
pledge or otherwise transfer the Debentures or any interest therein except in
compliance with, such restrictions and conditions and the United States
Securities Act of 1933, as amended (the "SECURITIES Act").

      2. We understand that the offer and sale of the Debentures have not been
registered under the Securities Act, and that the Debentures and any interest
therein may not be offered or sold except as permitted in the following
sentence. We agree, on our own behalf and on behalf of any accounts for which we
are acting as hereinafter stated, that if we should sell the Debentures or any
interest therein, we will do so only (A) to the Company or any of their
respective subsidiaries, (B) in accordance with Rule 144A under the Securities
Act to a "qualified institutional

                                      D-1

buyer" (as defined therein), (C) inside the United States to an institutional
"accredited investor" (as defined below) purchasing for its own account or for
the account of another institutional accredited investor that, prior to such
transfer, furnishes (or has furnished on its behalf by a U.S. broker-dealer) to
you and to the Company a signed letter substantially in the form of this letter
and, if the proposed transfer is in respect of an aggregate principal amount of
Debentures of less than $250,000, an Opinion of Counsel in form reasonably
acceptable to the Company to the effect that such transfer is in compliance with
the Securities Act, (D) outside the United States in accordance with Rule 904 of
Regulation S under the Securities Act, (E) pursuant to the provisions of Rule
144 under the Securities Act (if available), (F) in accordance with another
exemption from the registration requirements of the Securities Act (and based
upon an opinion of counsel acceptable to the Company) or (G) pursuant to an
effective registration statement under the Securities Act, and we further agree
to provide to any person purchasing the Definitive Debenture from us in a
transaction meeting the requirements of clauses (A) through (F) of this
paragraph a notice advising such purchaser that resales thereof are restricted
as stated herein.

      3. We understand that, on any proposed resale of the Debentures or
beneficial interest therein, we will be required to furnish to you and the
Company such certifications, legal opinions and other information as you and the
Company may reasonably require to confirm that the proposed sale complies with
the foregoing restrictions. We further understand that the Debentures purchased
by us will bear a legend to the foregoing effect. We further understand that any
subsequent transfer by us of the Debentures or beneficial interest therein
acquired by us must be effected through one of the Initial Purchasers.

      4. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and have
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risks of our investment in the Debentures, and we
and any accounts for which we are acting are each able to bear the economic risk
of our or its investment.

      5. We are acquiring the Debentures or beneficial interest therein
purchased by us for our own account or for one or more accounts (each of which
is an institutional "accredited investor") as to each of which we exercise sole
investment discretion.

      You and the Company are entitled to rely upon this letter and are
irrevocably authorized to produce this letter or a copy hereof to any interested
party in any administrative or legal proceedings or official inquiry with
respect to the matters covered hereby.
