than Trust PIERS in book-entry form (“Non Book-Entry Trust PIERS”) will be deemed to represent beneficial interests in Debentures presented to the Trustee by the Property Trustee having an aggregate principal amount equal to the
aggregate liquidation amount of the Non Book-Entry Trust PIERS until such Trust PIERS certificates are presented to the security registrar for the Debentures for transfer or reissuance, at which time such Trust PIERS certificates will be cancelled
and a Debenture, registered in the name of the holder of the Trust PIERS certificate or the transferee of the holder of such Trust PIERS certificate, as the case may be, with an aggregate principal amount equal to the aggregate liquidation amount of
the Trust PIERS certificate cancelled, will be executed by the Company and delivered to the Trustee for authentication and delivery in accordance herewith. Upon the issuance of any such Definitive Debentures, Debentures with an equivalent aggregate
principal amount that were presented by the Property Trustee to the Trustee will be cancelled. 
  
 (b) The Global Securities shall represent the aggregate amount of outstanding Debentures from time to time endorsed thereon; provided that the aggregate amount of outstanding Debentures represented thereby may from
time to time be reduced or increased, as appropriate, to reflect exchanges, conversions and redemptions. Any endorsement of a Global Security to reflect the amount of any increase or decrease in the amount of outstanding Debentures represented
thereby shall be made by the Trustee, in accordance with instructions given by the Company as required by this Section 2.03. 
  
 (c) The Global Securities may be transferred, in whole but not in part, only to the Depositary, another nominee of the Depositary, or to a successor
Depositary selected or approved by the Company or to a nominee of such successor Depositary. 
  
 SECTION 2.04 Applicability of Certain Provisions. The provisions of Section 2.08 of the Base Indenture shall apply to the Debentures except to the extent such provisions are inconsistent with this Article II,
in which case this Article II shall govern. 
  
 SECTION 2.05
Interest and Contingent Interest. (a) The Debentures shall bear interest at a rate of 4.00% per annum (the “Coupon Rate”) on the principal amount thereof, from and including December 15, 2004, payable quarterly in arrears on
March 15, June 15, September 15 and December 15 of each year (each an “Interest Payment Date”), beginning March 15, 2005 to the persons in whose names the Debentures are registered at the close of business on the day next preceding
the Interest Payment Date. If the Trust PIERS do not remain in book-entry only form and the Debentures are not in the form of a Global Security, the Company will have the right to select record dates, which must be at least one Business Day before
an Interest Payment Date (whether or not a Business Day), immediately preceding such Interest Payment Date. The amount of interest payable for any full quarterly interest period will be computed on 

  

 -10- 








 
the basis of a 360-day year of twelve 30-day months. The amount of interest payable for any period shorter than a full 90-day quarterly interest period for
which interest is computed, will be computed on the basis of 30-day months and, for periods of less than a full calendar month, the actual number of days elapsed per 30-day month. In the event that any Interest Payment Date on the Debentures is not
a Business Day, then payment of the interest 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 is in the
next succeeding calendar year, then such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. Any such interest installment, including contingent interest, not
punctually paid or duly provided for (excluding installments of interest (other than contingent interest) that are subject to an Extension Period) shall forthwith cease to be payable to the Holders on such Regular Record Date and shall be paid to
the Person in whose name the Debenture is registered at the close of business on a special record date to be fixed by the Company for the payment of such defaulted interest, provided that no special record date shall be less than 10 days prior to
the related payment date for such defaulted interest or may be paid at any time in any other lawful manner deemed practicable by the Trustee after notice thereof by the Company to the Trustee. 
  
 (b) Subject to the accrual and record date provisions specified herein and in
the Debenture, the Company shall pay contingent interest to the Holders during any quarterly period (a “Contingent Interest Period”) from March 15 to June 14, June 15 to September 14, September 15 to December 14 or December 15 to
March 14, commencing with the Contingent Interest Period beginning June 15, 2009, if the average of the Trading Prices of the Trust PIERS or, following any Dissolution Event, the Debentures for the five consecutive Trading Days ending on the second
Trading Day preceding such Contingent Interest Period (the “Five Trading Day Period”) equals 115% or more of the stated liquidation amount of the Trust PIERS or principal amount of the Debentures, as the case may be. 
  
 (c) The amount of contingent interest payable in respect of any Contingent
Interest Period will equal 0.125% of the average Trading Price of the Trust PIERS (or of the Debentures following any distribution of the Debentures to the holders of the Trust PIERS following a Dissolution Event) over the Five Trading Day Period
preceding such Contingent Interest Period. Contingent interest shall only be paid in cash. Contingent interest, if any, will accrue and be payable to Holders in the same manner as regular cash interest as provided above. Regular cash interest will
continue to accrue at the rate of 4.00% per year on the principal amount of the Debentures whether or not contingent interest is paid. 
  
 (d) Upon a determination by the Company that Holders will be entitled to receive contingent interest which will become payable during a Contingent
Interest Period, on or prior to the first day of such Contingent Interest Period, the Company shall deliver an Officer’s Certificate to the Trustee setting forth in a schedule the amount of such contingent interest per $50 principal amount of
Debentures and shall issue a press release with respect to the amount of such contingent interest. For purposes of determining the amount of an interest payment on a Debenture on any given Interest Payment Date, the Trustee may assume that Holders
are not entitled to receive contingent interest unless the Trustee has received an Officer’s Certificate stating that the condition for a Contingent Interest Period has been satisfied and specifying the amount of contingent interest payable per
$50 principal amount of Debentures. 
  

 -11- 








 (e) Interest on Debentures converted after the close of business on a Regular Record Date, but prior to
the opening of business on the corresponding Interest Payment Date, will be paid to the Holder of such Debentures on the Regular Record Date but, upon conversion, the Holder must pay the Company the interest, including contingent interest, which has
accrued and will be paid to the Holder on such Interest Payment Date in accordance with and subject to the penultimate paragraph of Section 7.02. No such payment by the Holder need be made with respect to Debentures in respect of which a Redemption
Date has been declared that falls prior to or on such Interest Payment Date or in the case of Debentures surrendered for conversion after such Debentures have been called for redemption during an Extension Period. 
  
 SECTION 2.06 Tax Treatment. The Company agrees, and by receiving a
beneficial ownership interest in the Debentures each Holder, and any Person (including an entity) that acquires a direct or indirect beneficial interest in the Debentures (including holders of Trust PIERS), will be deemed to have agreed (i) for
United States federal income tax purposes, (A) to treat the Debentures as indebtedness of the Company and (B) to treat the Debentures as indebtedness of the Company that is subject to Treas. Reg. Sec. 1.1275-4 (the “Contingent Payment
Regulations”), (ii) for United States federal income tax purposes, to treat the Trust PIERS as evidence of ownership of an undivided interest in the Debentures, (iii) for United States federal income tax purposes, to treat the exchange for
the Trust PIERS of the Trust Preferred Income Equity Redeemable Securities of Omnicare Capital Trust I due 2033 that were issued on June 13, 2003 as not constituting an exchange under section 1001 of the Internal Revenue Code of 1986, as amended,
(iv) for purposes of the Contingent Payment Regulations, to treat the fair market value of any stock beneficially received by a beneficial holder upon any conversion of the Debentures as a contingent payment, (v) to be bound by the Company’s
determination that the Debentures are contingent payment debt instruments subject to the “noncontingent bond method” of accruing original issue discount within the meaning of the Contingent Payment Regulations with respect to the
Debentures, (vi) to accrue original issue discount at the comparable yield as determined by the Company and (vii) to be bound by the Company’s projected payment schedule with respect to the Debentures. The parties hereto acknowledge that, the
comparable yield and the schedule of projected payments are not determined for any purpose other than for the determination of interest accruals and adjustment thereof in respect of the Debentures for United States federal income tax purposes; and
that the comparable yield and the schedule of projected payments do not constitute a projection or representation regarding the future stock price or the amounts payable on the Debentures. For purposes of the foregoing, the Company’s
determination of the “comparable yield” is 8.01% per annum, compounded quarterly. A Holder of Debentures may obtain the amount of original issue discount, issue date, comparable yield and projected payment schedule by submitting a written
request to: Omnicare, Inc., 100 East RiverCenter Boulevard, Covington, Kentucky 41011, Attention: Chief Financial Officer. 
  
 SECTION 2.07 Payment of Interest or Contingent Interest. Interest on any Debentures that is payable, and is punctually paid or duly provided for,
on any Interest Payment Date shall be paid to the Person in whose name such Debentures are registered at the close of business on the Regular Record Date, as the case may be, for such interest at the office or agency of the Company maintained for
such purpose. 
  

 -12- 








 SECTION 2.08 Register of Securities; Paying Agent; Conversion Agent. Initially, the Trustee
shall act as Paying Agent, Conversion Agent and Security Registrar for the Debentures. The Company may appoint and change any Paying Agent, Conversion Agent, Security Registrar or co-registrar or approve a change in the office through which any
Paying Agent acts without notice, other than notice to the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may act as Paying Agent, Conversion Agent, Security Registrar or co-registrar. 
  
 SECTION 2.09 Calculations in Respect of the Debentures. The Company
will be responsible for making all calculations called for under the Debentures. These calculations include, but are not limited to, determination of the Closing Price and the Current Market Price (as defined in Section 7.05(h) hereof), accrued
interest and contingent interest payable on the Debentures and the Conversion Price of the Debentures. The Company will make these calculations in good faith and, absent manifest error, these calculations will be final and binding on the Holders.
The Company will provide to each of the Trustee and the Conversion Agent a schedule of its calculations and each of the Trustee and the Conversion Agent is entitled to rely conclusively upon the accuracy of such calculations without independent
verification. The Trustee will forward the Company’s calculations to any Holder upon the request of such Holder. 
  
 SECTION 2.10 Form. The Debentures will be in substantially the form set forth in Exhibit A hereto, and may have such other terms as are provided
therein. 
  
 ARTICLE III 
 ADDITIONAL COVENANTS APPLICABLE TO THE DEBENTURES 
  
 In addition to the covenants set forth in Article 4 of the Base Indenture, the Debentures shall be subject to the additional covenants set forth in this
Article III: 
  
 SECTION 3.01 Offer to Repurchase Upon Change
of Control. (a) (a) If a Change of Control shall occur, each Holder of Debentures will have the right to require the Company to repurchase all or any part (equal to $50 or an integral multiple of $50) of that Holder’s Debentures pursuant to
a Change of Control offer (the “Change of Control Offer”) on the terms set forth herein. In the Change of Control Offer, the Company will offer a Change of Control payment (the “Change of Control Payment”) in cash
equal to 100% of the aggregate principal amount of Debentures repurchased plus accrued and unpaid interest (including contingent interest, if any) on the Debentures repurchased, to the Change of Control Payment Date (as defined below). Within 30
days following any Change of Control, the Company will mail a notice to the Trustee, the Paying Agent for the Debentures, if other than the Trustee, and each Holder describing the transaction or transactions that constitute the Change of Control and
offering to repurchase Debentures on the payment date (the “Change of Control Payment Date”) specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed, pursuant
to the procedures required hereby and described in such notice. The Company will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are
applicable in connection with the repurchase of the Debentures as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions hereof, the Company will comply
with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 3.01 by virtue of such conflict.

 (i) accept for payment all Debentures or portions of
Debentures properly tendered pursuant to the Change of Control Offer; 
  
 (ii) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Debentures or portions of Debentures properly tendered; and 
  
 (iii) deliver or cause to be delivered to the Trustee the
Debentures properly accepted, together with an Officers’ Certificate stating the aggregate principal amount of Debentures or portions of Debentures being purchased by the Company.

Debentures, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Debenture equal in principal amount to any unpurchased portion of the Debentures surrendered, if any; provided
that each new Debenture will be in a principal amount of $50 or an integral multiple of $50. 
  
 (b) The Company and the Trustee acknowledge that, upon the occurrence of a Change of Control, each holder of Trust PIERS shall have the right to exchange all or any portion of such holder’s Trust PIERS for
Debentures having a principal amount equal to the liquidation amount of such Trust PIERS and to simultaneously require the Company to repurchase such Debentures at the price and on the terms specified in Section 3.01(a) hereto. Any Trust PIERS as to
which such right is exercised will be exchanged by the Company not less than three Business Days prior to the Change of Control Payment Date.

 (iii) the payment of any dividend within 60
days after the date of declaration of such dividend if, at the date of declaration, (a) if paid on such declaration date the payment of such dividend would not have been prohibited by an election to defer interest payments under Section 6.01 hereof

Period; or 
  
 (viii) repurchases of the

businesses); 
  
 (b) make any payment of interest, principal or
premium, if any, on or repay, repurchase or redeem any debt securities (including other junior subordinated debentures) issued by the Company that expressly rank pari passu with or junior or subordinated to the Debentures, in each case other

 (c) make any guarantee payments with respect to any guarantee by the Company of the debt securities (including other guarantees) of any of its
Subsidiaries, if such guarantee is expressed to rank pari passu with or junior or subordinated in interest to the Debentures, other than payments under the Trust PIERS Guarantee or any other similar guarantee in respect of future issuances of
Trust PIERS or any other trust preferred securities; 
  
 if at such time (1) an
event has occurred that with the giving of notice or the lapse of time, or both, would constitute an Event of Default and the Company has not taken reasonable steps to cure such event, (2) the Company shall be in default with respect to its payment
obligations under the Trust PIERS Guarantee or (3) the Company shall have given notice of its intention to begin an Extension Period pursuant to Section 6.01 of this Third Supplemental Indenture and has not rescinded the notice, or any such

provided, however, that any successor of the Company permitted pursuant to Article 5 of the Base Indenture may succeed to the Company’s ownership of such Trust Common Securities, (b) will use commercially reasonable efforts to
cause the Trust to remain a statutory trust, except in connection with a distribution of Debentures to the holders of Trust Securities in connection with a Dissolution Event; (c) will not voluntarily terminate, wind-up or liquidate the Trust, except

company” within the meaning of the Investment Company Act of 1940 or the rules and regulations of the SEC thereunder. 
  
 SECTION 3.04 Payment of Expenses. The Company, in its capacity as borrower with respect to the Debentures, shall:

occurred and is continuing, the Company shall have the right, at any time following the occurrence of such Special Event, upon (i) not less than 35 days (or such shorter period as may be acceptable to the Trustee) nor more than 75 days before a
Redemption Date, written notice to the Trustee and (ii) not less than 30 days nor more than 60 days written notice to the Holders, to redeem the Debentures, in whole (but not in part), at a purchase price equal to 100% of the principal amount to be

 ARTICLE V 
 SUBORDINATION OF DEBENTURES 
  
 The Debentures shall not be subject to Article 11 of the Base Indenture. In lieu thereof, the Debentures shall be subject to the following provisions of this Article V: 
  
 SECTION 5.01 Agreement to Subordinate. The Company covenants and
agrees, and each Holder of Debentures issued hereunder likewise covenants and agrees, that the Debentures shall be issued subject to the provisions of this Article V; and each Holder of a Debenture, whether upon original issue or upon transfer or
assignment thereof, accepts and agrees to be bound by such provisions. 
  

 -17- 








 The payment by the Company of the principal of and interest, including contingent interest, on all
Debentures issued hereunder shall, to the extent and in the manner hereinafter set forth, be subordinated and junior in right of payment to all Senior Indebtedness, whether outstanding at the date of this Indenture or thereafter incurred.

  
 No provision of this Article V shall prevent the occurrence of
any Default or Event of Default hereunder. 
  
 SECTION 5.02
Default on Senior Indebtedness. In the event and during the continuation of any Default by the Company in the payment of principal, interest or any other payment due on any Senior Indebtedness, or in the event that the maturity of any Senior
Indebtedness has been accelerated because of an Event of Default, or if any judicial proceeding shall be pending with respect to any such Default, then, in any such case, no payment shall be made by the Company with respect to the principal
(including redemption payments) of or interest (including contingent interest) on the Debentures or any other amounts which may be due on the Debentures pursuant to the terms hereof or otherwise. 
  
 In the event of the acceleration of the maturity of the Debentures, then no
payment shall be made by the Company with respect to the principal (including redemption payments) or interest (including contingent interest) on the Debentures or any other amounts which may be due on the Debentures pursuant to the terms hereof or
otherwise until the holders of all Senior Indebtedness outstanding at the time of such acceleration shall receive payment in full of such Senior Indebtedness (including any amounts due upon acceleration). 
  
 In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee or Holders of Debentures when such payment is prohibited by the preceding paragraphs of this Section 5.02 and at a time when a Responsible Officer of the Trustee or such Holder has actual knowledge that such payment should
not have been made to it, such payment shall be held in trust for the benefit of, and shall be paid over or delivered to, the holders of Senior Indebtedness or their respective representatives, or to the trustee or trustees under any indenture
pursuant to which any of such Senior Indebtedness may have been issued, as their respective interests may appear, but only to the extent that the holders of the Senior Indebtedness (or their representative or representatives or a trustee) notify the
Trustee in writing within 90 days of such payment of the amounts then due and owing on such Senior Indebtedness, and only the amounts specified in such notice to the Trustee shall be paid to the holders of such Senior Indebtedness. 
  
 SECTION 5.03 Liquidation; Dissolution; Bankruptcy. Upon any payment by
the Company or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to creditors upon the Company’s liquidation, dissolution, winding up, reorganization, assignment for the benefit of its
creditors, marshaling of its assets or any bankruptcy, insolvency, debt restructuring or similar proceedings in connection with any insolvency or bankruptcy proceeding involving the Company, all Senior Indebtedness of the Company shall first be paid
in full, or payment thereof provided for in money in accordance with its terms, before any payment is made by the Company on account of the principal of or interest 

  

 -18- 








 
(including contingent interest) on the Debentures or any other amounts which may be due on the Debentures pursuant to the terms hereof or otherwise; and upon
any such event, any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, which the Holders or the Trustee would be entitled to receive from the Company, except for the
provisions of this Article V, shall be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the Holders or by the Trustee if received by them or it,
directly to the holders of Senior Indebtedness of the Company (pro rata to such holders on the basis of the respective amounts of Senior Indebtedness held by such holders, as calculated by the Company) or their representative or representatives, or
to the trustee or trustees under any indenture pursuant to which any instruments evidencing such Senior Indebtedness may have been issued, as their respective interests may appear, to the extent necessary to pay all such Senior Indebtedness in full,
in money or money’s worth, after giving effect to any concurrent payment or distribution to or for the holders of such Senior Indebtedness, before any payment or distribution is made to the Holders or to the Trustee. 
  
 In the event that, notwithstanding the foregoing, any payment or distribution
of assets of the Company of any kind or character prohibited by the foregoing and at a time when a Responsible Officer of the Trustee or such Holder has actual knowledge that such payment should not have been made to it, whether in cash, property or
securities, shall be received by the Trustee before all Senior Indebtedness is paid in full, or provision is made for such payment in money in accordance with its terms, such payment or distribution shall be held in trust for the benefit of and
shall be paid over or delivered to the holders of such Senior Indebtedness or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing such Senior Indebtedness may have
been issued, as their respective interests may appear, as calculated by the Company, for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to pay all such Senior Indebtedness in full in money in
accordance with its terms, after giving effect to any concurrent payment or distribution to or for the benefit of the holders of such Senior Indebtedness. 
  
 For purposes of this Article V, the words “cash, property or securities” shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other company provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in this Article V with respect to the
Debentures to the payment of Senior Indebtedness that may at the time be outstanding, provided that (i) such Senior Indebtedness is assumed by the new company, if any, resulting from any such reorganization or readjustment, and (ii) the rights of
the holders of such Senior Indebtedness are not, without the consent of such holders, altered by such reorganization or readjustment. The consolidation of the Company with, or the merger of the Company into, another Person or the liquidation or
dissolution of the Company following the sale, conveyance, transfer or lease of its property as an entirety, or substantially as an entirety, to another Person upon the terms and conditions provided for in Article 5 of the Base Indenture shall not
be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this Section 5.03 if such other Person shall, as a part of such consolidation, merger, sale, conveyance, transfer or lease, comply with the conditions stated in
Article 5 of the Base Indenture. Nothing in Section 5.02 or in this Section 5.03 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 7.07 of the Base Indenture. 
  

 -19- 








 SECTION 5.04 Subrogation. Senior Indebtedness shall not be deemed to have been paid in full unless
the holders thereof shall have received cash, securities or other property equal to the amount of such Senior Indebtedness then outstanding. After all Senior Indebtedness is paid in full and until the Debentures are paid in full, the Holders shall
be subrogated (equally and ratably with all other indebtedness as to which the right to receive payment is pari passu with the Debentures) to the rights of holders of Senior Indebtedness to receive payments applicable to Senior Indebtedness
to the extent that payments otherwise payable to the Holders have been applied to the payment of Senior Indebtedness, and such payments received by any Holder of Debentures, by reason of such subrogation, of cash, securities or other property which
otherwise would be paid to the holders of Senior Indebtedness, shall, as between the Company and its creditors other than the holders of Senior Indebtedness, on the one hand, the Holders of Debentures, on the other, be deemed to be a payment by the
Company on account of Senior Indebtedness, and not on account of Debentures. It is understood that the provisions of this Article V are and are intended solely for the purposes of defining the relative rights of the holders of the Debentures, on the
one hand, and the holders of such Senior Indebtedness on the other hand. 
  
 Nothing contained in this Article V or elsewhere in this Third Supplemental Indenture or in the Debentures is intended to or shall impair, as between the Company, its creditors other than the holders of Senior
Indebtedness of the Company, and the holders of the Debentures, the obligation of the Company, which is absolute and unconditional, to pay to the Holders the principal of and interest (including contingent interest) on the Debentures as and when the
same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the holders of the Debentures and creditors of the Company, as the case may be, other than the holders of Senior Indebtedness
of the Company, as the case may be, nor shall anything herein or therein prevent the Trustee or the Holder of any Debenture from exercising all remedies otherwise permitted by applicable law upon Default under this Third Supplemental Indenture,
subject to the rights, if any, under this Article V of the holders of such Senior Indebtedness in respect of cash, property or securities of the Company, as the case may be, received upon the exercise of any such remedy. 
  
 Upon any payment or distribution of assets of the Company referred to in this
Article V, the Trustee, subject to the provisions of Article 7 of the Base Indenture, and the holders shall be entitled to conclusively rely upon any order or decree made by any court of competent jurisdiction in which such dissolution, winding-up,
liquidation or reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidation trustee, agent or other Person making such payment or distribution, delivered to the Trustee or to the holders, for the
purposes of ascertaining the Persons entitled to participate in such distribution, the holders of Senior Indebtedness and other indebtedness of the Company, as the case may be, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article V. 
  
 SECTION 5.05 Trustee to Effectuate Subordination. Each Holder by such 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 provided in this Article V and appoints the Trustee such Holder’s attorney-in-fact for any and all such purposes. 
  

 -20- 








 SECTION 5.06 Notice by the Company. The Company shall give prompt written notice to a Responsible
Officer of the Trustee of any fact known to the Company that would prohibit the making of any payment of monies to or by the Trustee in respect of the Debentures pursuant to the provisions of this Article V. Notwithstanding the provisions of this
Article V or any other provision of this Third Supplemental Indenture, neither the Trustee nor any Responsible Officer shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment of monies to or by
the Trustee in respect of the Debentures pursuant to the provisions of this Article V, unless and until a Responsible Officer of the Trustee shall have received written notice thereof from the Company or a holder or holders of Senior Indebtedness or
from any trustee therefor; and before the receipt of any such written notice, the Trustee, subject to the provisions of Article 7 of the Base Indenture, shall be entitled in all respects to assume that no such facts exist; provided,
however, that if the Trustee shall not have received the notice provided for in this Section 5.06 at least three Business Days prior to the date upon which by the terms hereof any money may become payable for any purpose (including, without
limitation, the payment of the principal of or interest on any Debenture), then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purposes
for which they were received, and shall not be affected by any notice to the contrary that may be received by it within three Business Days prior to such date. 
  

The Trustee, subject to the provisions of Article 7 of the Base Indenture, shall be entitled to conclusively rely on a written notice delivered to it
by a Person representing himself to be a holder of Senior Indebtedness of the Company (or a trustee on behalf of such holder), as the case may be, to establish that such notice has been given by a holder of such Senior Indebtedness or a trustee on
behalf of any such holder or holders. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of such Senior Indebtedness to participate in any payment or
distribution pursuant to this Article V, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of such Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article V, and, if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment. 
  
 Upon any payment or distribution of assets of the Company referred to in this Article V, the Trustee and the Holders shall be entitled to conclusively rely upon any order or decree entered by any court of competent jurisdiction in which
such insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding-up or similar case or proceeding is pending, or a certificate of the trustee in bankruptcy, liquidating trustee, custodian, receiver, assignee for the
benefit of creditors, agent or other person making such payment or distribution, delivered to the Trustee or to the Holders, for the purpose of ascertaining the persons entitled to participate in such payment or distribution, the holders of Senior
Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article V. 
  
 SECTION 5.07 Rights of the Trustee; Holders of Senior Indebtedness.
The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article V in respect of any 

  

 -21- 








 
Senior Indebtedness at any time held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Third Supplemental Indenture
shall deprive the Trustee of any of its rights as such holder. 
  
 With respect to the holders of Senior Indebtedness of the Company, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article V, and no implied covenants or
obligations with respect to the holders of such Senior Indebtedness shall be read into this Third Supplemental Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of such Senior Indebtedness and,
subject to the provisions of Article 7 of the Base Indenture, the Trustee shall not be liable to any holder of such Senior Indebtedness if it shall pay over or deliver to holders, the Company or any other Person money or assets to which any holder
of such Senior Indebtedness shall be entitled by virtue of this Article V or otherwise. 
  
 Nothing in this Article V shall apply to claims of, or payments to, the Trustee under or pursuant to Section 7.07 of the Base Indenture. 
  
 SECTION 5.08 Subordination May Not Be Impaired. No right of any present or future holder of any Senior Indebtedness
of the Company to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company, as the case may be, or by any act or failure to act, in good faith, by any
such holder, or by any noncompliance by the Company, as the case may be, with the terms, provisions and covenants of this Third Supplemental Indenture, regardless of any knowledge thereof that any such holder may have or otherwise be charged with.

  
 Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Indebtedness of the Company may, at any time and from time to time, without the consent of or notice to the Trustee or the holders, without incurring responsibility to the holders and without impairing or releasing
the subordination provided in this Article V or the obligations hereunder of the holders of the Debentures to the holders of such Senior Indebtedness, 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, such Senior Indebtedness, or otherwise amend or supplement in any manner such Senior Indebtedness or any instrument evidencing the same or any agreement under which such Senior Indebtedness is outstanding;
(ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing such Senior Indebtedness; (iii) release any Person liable in any manner for the collection of such Senior Indebtedness; and (iv) exercise or
refrain from exercising any rights against the Company, as the case may be, and any other Person. 
  
 ARTICLE VI 
 EXTENSION OF INTEREST PAYMENT PERIOD 
  
 SECTION 6.01 Extension of Interest Payment Period. So long as the
Company is not in Default in the payment of interest, including contingent interest, if any, on the Debentures, the Company shall have the right, at any time and from time to time during the term of the Debentures, to defer payments of interest,
other than contingent interest, by extending the interest payment period of such Debentures for a period not exceeding 20 consecutive quarterly 

  

 -22- 








 
periods, including the first such quarterly period during such extension period (an “Extension Period”), during which Extension Period no
interest (other than contingent interest) shall be due and payable; provided that no Extension Period shall extend beyond the Stated Maturity or, with respect to any Debentures called for redemption, the Redemption Date with respect to such
Debentures. To the extent permitted by applicable law, interest, the payment of which has been deferred because of the extension of the interest payment period pursuant to this Section 6.01, will bear interest thereon at the Coupon Rate compounded
quarterly for each quarterly period of the Extension Period (“Compounded Interest”). At the end of the Extension Period, which is an Interest Payment Date, the Company shall pay all interest accrued and unpaid on the Debentures
(together, “Deferred Interest”) that shall be payable to Holders on the Regular Record Date immediately preceding the end of the Extension Period. Before the termination of any Extension Period, the Company may further defer
payments of interest (other than contingent interest) by further extending such period, provided that such period, together with all such previous and further extensions within such Extension Period, shall not exceed 20 consecutive quarterly
periods, including the first such quarterly period during such Extension Period, or extend beyond the Stated Maturity of the Debentures or, with respect to any Debentures called for redemption, the Redemption Date with respect to such Debentures. If
any Extension Period ends on a day that is not an Interest Payment Date, then on or prior to the last day of such Extension Period, the Company shall deposit with the Trustee the full amount of unpaid interest (other than contingent interest) that
has accrued on the Debentures through the last Interest Payment Date that falls prior to the last day of the Extension Period, and on the Interest Payment Date following the last day of the Extension Period, all unpaid interest accrued on the
Debentures through that following Interest Payment Date will be due and payable unless the Company further extends the Extension Period to a later date, in which case the amounts deposited with the Trustee shall be returned to the Company. Upon the
termination of any Extension Period and the payment of all Deferred Interest then due, the Company may commence a new Extension Period, subject to the foregoing requirements. No interest (other than contingent interest) shall be due and payable
during an Extension Period, except at the end thereof, but the Company may prepay at any time all or any portion of the interest accrued during an Extension Period. The payment of contingent interest may not, under any circumstances, be subject to
an Extension Period. 
  
 SECTION 6.02 Notice of Extension.
(a) If the Property Trustee is the only registered Holder of the Debentures at the time the Company selects an Extension Period or extends an Extension Period, the Company shall give written notice to the Administrative Trustees, the Property
Trustee and the Trustee of its selection of such Extension Period or its extension of an Extension Period at least one Business Day before the earlier of (i) the next date on which distributions on the Trust PIERS are payable, or (ii) the date the
Administrative Trustee is required to give notice of the record date or the payment date of such related distributions for the first quarter of such Extension Period to any national stock exchange or other organization on which the Trust PIERS are
listed or quoted, if any, or to holders of the Trust PIERS as of the record date or the payment date. The Administrative Trustee will give notice of the Company’s election of the extension period to the holders of the Trust PIERS. 

 
 (b) If the Property Trustee is not the only Holder of the Debentures at
the time the Company selects an Extension Period or extends an Extension Period, the Company shall give the holders of the Debentures and the Trustee written notice of its selection of such 

  

 -23- 








 
Extension Period or its extension of an Extension Period at least 10 Business Days before the earlier of (i) the Interest Payment Date for the first quarter
of such Extension Period, or (ii) the date the Company is required to give notice of the record date or payment date of such related interest payment for the first quarter of such Extension Period to any national stock exchange or other organization
on which the Debentures are listed or quoted, if any, or to holders of the Debentures as of the record date or the payment date. 
  
 (c) The quarterly period in which any notice is given pursuant to paragraphs (a) or (b) of this Section 6.02 shall be counted as one of the 20 quarterly
periods permitted in the maximum Extension Period permitted under Section 6.01. 
  
 ARTICLE VII 
 CONVERSION OF DEBENTURES 
  
 SECTION 7.01 Conversion Rights (a) (a) Subject to and upon compliance with the provisions of this Article VII, the
Debentures are convertible, at the option of the Holder, at any time on and after the occurrence of any of the events described in paragraph (b) below, and before 5:00 pm, New York time, on the Business Day immediately preceding the date of
repayment of such Debentures, whether at Stated Maturity or upon redemption, into a cash amount and, if applicable, fully paid and nonassessable shares of Common Stock. Debentures will be converted at an initial conversion ratio of 1.2248 shares of
Common Stock for each $50 in aggregate principal amount of Debentures, subject to adjustment as described in this Article VII. Following any adjustment to the Conversion Price in accordance with Section 7.05, the Conversion Ratio shall be equal to
the quotient of $50 divided by the Conversion Price in effect following such adjustment (as so adjusted, the “Conversion Ratio”). A Holder may convert any portion of the principal amount of such Holder’s Debentures into a (x)
cash amount equal to the lesser of (i) the aggregate principal amount of the Debentures to be converted or (ii) the Applicable Stock Price (as defined below) multiplied by the Conversion Ratio (multiplied by the aggregate principal amount of
Debentures to be converted divided by 50) and (y) if the product of the Applicable Stock Price and the Conversion Ratio (multiplied by the aggregate principal amount of Debentures to be converted divided by 50) exceeds the aggregate principal amount
of Debentures to be converted, that number of fully paid and nonassessable shares of Common Stock (calculated as to each conversion to the nearest 1/100th of a share) equal to (i) the aggregate principal amount of Debentures to be converted divided
by $50 and multiplied by (ii)(A) the Conversion Ratio minus (B) $50 divided by the Applicable Stock Price. Settlement in cash and, if applicable, shares of Common Stock, will occur on the second Trading Day following the final trading day of the
Cash Settlement Averaging Period. Such day will be the 22nd Trading Day following the Property Trustee’s receipt of a conversion notice submitted by the holder of Trust PIERS (assuming such holder has satisfied all conversion requirements,
including the valid delivery of the conversion notice), unless (i) the conversion is in connection with a redemption, in which case the settlement day will be the redemption date or (ii) such holder of Trust PIERS submits a conversion notice during
the period beginning 25 Trading Days preceding the maturity date and ending one Trading Day preceding the maturity date, in which case the settlement day will be the maturity date. 
  
 (b) “Applicable Stock Price” shall mean, in respect of a conversion date, the average Closing Sale Price of
Common Stock over the 20 Trading-Day period (the “Cash  

  

 -24- 








 
Settlement Averaging Period”) beginning on the Trading Day following the receipt by the Property Trustee of a conversion notice from a holder of
Trust PIERS; provided that, such conversion notice satisfies the requirements set forth in the Trust Agreement and that all other conversion requirements described therein have been satisfied; provided further that, if a holder of Trust PIERS
submits such conversion notice during the period beginning 25 Trading Days preceding the maturity date of the Debentures and ending one Trading Day preceding such maturity date, then the Cash Settlement Averaging Period will be the 20 Trading-Day
period ending on the second Trading Day preceding such maturity date; provided further that, if the Debentures have been called for redemption, then the Cash Settlement Averaging Period will be the 20 Trading-Day period ending on the second Trading
Day preceding the Redemption Date. 
  
 (c) Conversion Rights
Based on Common Stock Price. If, as of the last day of any calendar quarter beginning with the quarter ending March 31, 2005, the Closing Sale Price of the Common Stock on each of at least 20 Trading Days in a period of 30 consecutive Trading
Days ending on the last Trading Day of such quarter is more than 130% of the Conversion Price in effect on the last day of such quarter, then on and after the first day of the following calendar quarter (and only during such following calendar
quarter), Holders may surrender their Debentures for conversion into shares of Common Stock at any time at their option until 5:00 p.m., New York time, on the Business Day immediately preceding the Stated Maturity or earlier Redemption Date.

  
 (d) Conversion Rights Based on Notice of Redemption. A
Holder may surrender for conversion a Debenture that has been called for redemption at any time prior to 5:00 p.m., New York time, on the day that is two Business Days immediately preceding the date of redemption, even if such Debenture is not
otherwise convertible at that time. 
  
 (e) Conversion Rights
Based on Trust PIERS Trading Price. Holders may also surrender a Debenture for conversion during the five-Business-Day period following any 10-consecutive-Trading-Day period in which the average of the Trading Prices for the Trust PIERS (or, if
the Debentures have been distributed to the holders of Trust PIERS, the average of the Trading Prices for the Debentures) for such 10-Trading-Day period was less than a Specified Trigger Percentage (as defined below) of the average of the Conversion
Values for the Trust PIERS or the Debentures, as the case may be, for each day during such period. The “Specified Trigger Percentage” will be 105% for any 10-Trading-Day period that ends before June 15, 2028 and 98% for any
10-Trading-Day period ending on or after that date. 
  
 (f)
Conversion Rights Based on Occurrence of Certain Corporate Transactions. 
  
 If: 
  
 (i) the
Company shall distribute to all holders of its Common Stock rights or warrants entitling such holders to subscribe for or purchase, for a period expiring within 60 days of the date of any such distribution, Common Stock at a price per share less
than the Trading Price of the Common Stock on the Trading Day immediately preceding the date of the announcement of such distribution; 
  

 -25- 








 (ii) the Company elects to distribute to all holders of its Common Stock cash or other
assets, debt securities or rights or warrants to purchase its securities, which distribution has a per share value (as determined by the Company’s Board of Directors) exceeding 10% of the Trading Price of Common Stock on the Business Day
preceding the declaration date for the distribution; or 
  
 (iii) a Change of Control occurs but holders of Debentures do not have the right to require the Company to repurchase their Debentures as a result of such Change of Control because either (1) the trading price of
Common Stock during the period described in clause (x) of the definition of “Change of Control” set forth herein equals or exceeds the level specified in such definition or (2) the consideration received in such Change of Control consists
of common stock that is freely tradable and the Trust PIERS (or the Debentures following the distribution of the Debentures to the holders of the Trust PIERS) become convertible into cash and, if applicable, such common stock (as described in clause
(y) of the definition of “Change of Control” set forth herein), 
  
 then
the Company shall be required to notify the Holders of the Debentures at least 20 days prior to the ex-dividend date for the distribution or within 30 days of the occurrence of the Change of Control, as the case may be. Once the Company has given
such notice, Holders may surrender their Debentures for conversion at any time until either (a) the earlier of the close of business on the Business Day immediately prior to the ex-dividend date and the date on which the Company announces that the
distribution will not take place, in the case of a distribution or (b) 30 days after the date of the notice of the Change of Control, in the case of a Change of Control. A Holder will not have the right to convert Debentures as a result of a
distribution if such Holder has rights to participate, or will have such rights, in the distribution without conversion. 
  
 A Holder may not exercise conversion rights in respect of any Debenture in respect of which a Holder is exercising its option to require redemption upon a
Change of Control pursuant to Section 3.01. A Holder of Debentures is not entitled to any rights of a holder of Common Stock unless and 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 VII. 
  
 SECTION 7.02 Exercise of Conversion Privilege; Payment of Cash and Issuance of Common Stock on Conversion; No Adjustment for Interest or Dividends. In order to exercise the conversion privilege with respect to any Definitive
Debenture, the Holder of any such Debenture to be converted in whole or in part shall surrender such Debenture, duly endorsed, to the Conversion Agent, accompanied by the funds, if any, required by the penultimate paragraph of this Section 7.02, and
shall give written notice of conversion to the Conversion Agent in the form provided on the Debentures (or such other notice which is acceptable to the Company) that the Holder elects to convert such Debenture or the portion thereof specified in
said notice. Such notice shall also state the name or names (with address or addresses) to which the cash amount shall be paid and, if applicable, in which the certificate or certificates for shares of Common Stock shall be issued upon conversion,
and shall be accompanied by transfer taxes, if required pursuant to Section 7.07. In addition, a holder of Trust PIERS may exercise its right under the Trust Agreement to exchange such Trust PIERS for Debentures which shall be converted into cash
and, if applicable, Common Stock by delivering to the Conversion Agent irrevocable 

  

 -26- 








 
written notice setting forth the information called for by the preceding two sentences and directing the Conversion Agent (i) to exchange such Trust PIERS
for a Like Amount of the Debentures held by the Trust (at an exchange rate of $50 principal amount of Debentures for each Trust PIERS), and (ii) to immediately convert such Debentures, on behalf of such Holder, into cash and, if applicable, Common
Stock pursuant to this Article VII and, if such Trust PIERS are in certificate form, surrendering such Trust PIERS, duly endorsed or assigned to the Company or in blank. So long as any Trust PIERS are outstanding, the Trust shall not convert any
Debentures except pursuant to a written notice delivered to the Conversion Agent by a holder of Trust PIERS. Each such Debenture surrendered for conversion shall, unless the shares of Common Stock issuable on conversion are to be issued in the same
name as the registration of such Debenture, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or his duly authorized attorney. 
  
 In order to exercise the conversion privilege with respect to any interest in
a Debenture in global form, the Holder must complete the appropriate instruction form for conversion pursuant to the Depository’s book-entry conversion program, deliver by book-entry delivery the principal amount of the Debenture to be
converted, furnish appropriate endorsements and transfer documents if required by the Company or the Trustee or Conversion Agent, and pay the funds, if any, required by this Section 7.02 and any transfer taxes if required pursuant to Section 7.07.

  
 As promptly as practicable after satisfaction of the
requirements for conversion set forth above, subject to compliance with any restrictions on transfer if shares issuable on conversion are to be issued in a name other than that of the Holder (as if such transfer were a transfer of the Debenture or
Debentures (or portion thereof) so converted), the Company shall pay to such Holder at the office or agency maintained by the Company for such purpose pursuant to Section 2.07 of the Base Indenture, an amount of cash as specified in Sections 7.01
and 7.03 hereof and, if applicable, shall issue and deliver a certificate or certificates for the number of full shares of Common Stock issuable upon the conversion of such Debenture or portion thereof in accordance with the provisions of this
Article. In case any Debenture of a denomination greater than $1,000 shall be surrendered for partial conversion, and subject to the provisions hereof, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of the
Debenture so surrendered, without charge to him, a new Debenture or Debentures in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Debenture. 
  
 Each conversion shall be deemed to have been effected as to any such
Debenture (or portion thereof) on the date on which the requirements set forth above in this Section 7.02 have been satisfied as to such Holder of a Debenture (or portion thereof), or as to such holder of a Trust PIERS effecting a conversion thereof
pursuant to its rights under the Trust Agreement, as the case may be, and the person in whose name any certificate or certificates for shares of Common Stock shall be issued upon such conversion shall be deemed to have become on said date the holder
of record of the shares represented thereby; provided, however, that if on the effective date of such conversion the stock transfer books of the Company shall be closed, the person in whose name the certificates are to be issued shall not be
deemed the record owner thereof until the next succeeding day on which such stock transfer books are open, but such conversion shall be at the Conversion Price in effect on the date upon which such conversion becomes effective. 
  

 -27- 








 Any Debenture or portion thereof surrendered for conversion during the period from the close of business
on the record date for any Interest Payment Date to the close of business on the Business Day next preceding the following Interest Payment Date shall (unless such Debenture or portion thereof being converted shall have been called for redemption on
a Redemption Date which occurs during the period from the close of business on such record date to the close of business on the Business Day next preceding the following Interest Payment Date) be accompanied by payment (the “Interest Payment
Reimbursement”), in New York Clearing House funds or other funds acceptable to the Company, of an amount equal to the interest, including contingent interest, if any, otherwise payable on such Interest Payment Date on the principal amount
being converted. Notwithstanding the immediately preceding sentence, if (i) notice of redemption of Debentures is mailed or otherwise given to Holders and the related Redemption Date occurs during the period from the close of business on the record
date for any Interest Payment Date to the close of business on the Business Day next preceding the following Interest Payment Date, and Debentures or any portion thereof are surrendered for conversion after such record date but prior to such
Redemption Date, then the Holder surrendering such Debentures or portion thereof shall not be required to pay the Interest Payment Reimbursement, and (ii) during an Extension Period a notice of redemption of Debentures is mailed or otherwise given
to Holders and Debentures or any portion thereof are surrendered for conversion after such notice but prior to the relevant Redemption Date, then the Holder surrendering such Debentures or portion thereof shall not be required to pay the Interest
Payment Reimbursement and shall be entitled to receive payment of all accrued but unpaid interest, including contingent interest, if any, on such Debentures through the date of conversion on the Redemption Date. Except as otherwise set forth above
in this paragraph, in the case of any Debenture which is converted, interest or contingent interest which is payable after the date of conversion of such Debenture shall not be payable, and the Company shall not make nor be required to make any
other payment, adjustment or allowance with respect to accrued but unpaid interest or contingent interest on the Debentures being converted which shall be deemed to be paid in full. Except as provided above in this Section 7.02, no payment or other
adjustment shall be made for interest or contingent interest accrued on any Debenture converted or for dividends on any shares issued upon the conversion of such Debenture. 
  
 Upon the conversion of an interest in a Debenture in global form, the Trustee (or other Conversion Agent appointed by the
Company), or a custodian at the direction of the Trustee (or other Conversion Agent appointed by the Company), shall make a notation on such Debenture in global form as to the reduction in the principal amount represented thereby. The Company shall
notify the Trustee in writing of any conversions of Debentures effected through any Conversion Agent other than the Trustee. 
  
 SECTION 7.03 Cash Payments in Lieu of Fractional Shares. No fractional shares of Common Stock or scrip representing fractional shares shall be
issued upon conversion of Debentures. If more than one Debenture shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon conversion, if any, 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 stock would be issuable upon the conversion of any Debenture or Debentures, the Company shall make
an adjustment and payment therefor in cash at the Applicable Stock Price thereof to the Holder of Debentures. 
  

 -28- 








 SECTION 7.04 [Intentionally Omitted.] 
  
 SECTION 7.05 Adjustment of Conversion Price. The Conversion Price
shall be adjusted from time to time by the Company as follows: 
  
 (a) In case the Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Price in effect at the opening of business on the date following the date
fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be reduced by multiplying such Conversion Price by a fraction of which the numerator shall be the number of shares of Common Stock outstanding
at the close of business on the date fixed for such determination and the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such reduction to become effective
immediately after the opening of business on the day following the date fixed for such determination. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. If any dividend or
distribution of the type described in this Section 7.05(a) is declared but not so paid or made, the Conversion Price shall again be adjusted to the Conversion Price which would then be in effect if such dividend or distribution had not been
declared. 
  
 (b) In case the Company shall issue rights or
warrants to all holders of its outstanding shares of Common Stock entitling them (for a period expiring within forty-five (45) days after the date fixed for determination of stockholders entitled to receive such rights or warrants) to subscribe for
or purchase shares of Common Stock at a price per share less than the Current Market Price (as defined below) on the date fixed for determination of stockholders entitled to receive such rights or warrants, the Conversion Price shall be adjusted so
that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the date fixed for determination of stockholders entitled to receive such rights or warrants by a fraction of which the numerator shall
be the number of shares of Common Stock outstanding at the close of business on the date fixed for determination of stockholders entitled to receive such rights and warrants plus the number of shares which the aggregate offering price of the total
number of shares so offered would purchase at such Current Market Price, and of which the denominator shall be the number of shares of Common Stock outstanding on the date fixed for determination of stockholders entitled to receive such rights and
warrants plus the total number of additional shares of Common Stock offered for subscription or purchase. Such adjustment shall be successively made whenever any such rights and warrants are issued, and shall become effective immediately after the
opening of business on the day following the date fixed for determination of stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock are not delivered after the expiration of such rights or warrants, the
Conversion Price shall be readjusted to the Conversion Price which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock actually
delivered. In the event that such rights or warrants are not so issued, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such date fixed for the determination of stockholders entitled to
receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in determining the aggregate
offering price of 

  

 -29- 








 
such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights or warrants, the value of such
consideration, if other than cash, to be determined by the Board of Directors. 
  
 (c) In case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which
such subdivision becomes effective shall be proportionately reduced, and conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Price in effect at the opening of
business on the day following the day upon which such combination becomes effective shall be proportionately increased, such reduction or increase, as the case may be, to become effective immediately after the opening of business on the day
following the day upon which such subdivision or combination becomes effective. 
  
 (d) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of capital stock of the Company (other than any dividends or distributions to which Section
7.05(a) applies) or evidences of its indebtedness or assets (including securities, but excluding any rights or warrants referred to in Section 7.05(b), and excluding any dividend or distribution (x) paid exclusively in cash or (y) in connection with
a reclassification, change, consolidation, merger, combination, sale or conveyance that results in a change in the conversion consideration as described in Section 7.06 (any of the foregoing hereinafter in this Section 7.05(d) called the
“Securities”)), then, in each such case (unless the Company elects to reserve such Securities for distribution to the Holders upon the conversion of the Debentures so that any such Holder converting Debentures will receive upon such
conversion, in addition to the shares of Common Stock to which such Holder is entitled, the amount and kind of such Securities which such Holder would have received if such Holder had converted its Debentures into Common Stock immediately prior to
the Record Date (as defined in Section 7.05(h) for such distribution of the Securities)), the Conversion Price shall be reduced so that the same shall be equal to the price determined by multiplying the Conversion Price in effect on the Record Date
with respect to such distribution by a fraction of which the numerator shall be the Current Market Price per share of the Common Stock on such Record Date less the Fair Market Value (as determined by the Board of Directors, whose determination shall
be conclusive, and described in a resolution of the Board of Directors) on the Record Date of the portion of the Securities so distributed applicable to one share of Common Stock and the denominator shall be the Current Market Price per share of the
Common Stock, such reduction to become effective immediately prior to the opening of business on the day following such Record Date; provided, however, that in the event the fair market value (as so determined) of the portion of the
Securities so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price of the Common Stock on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder
shall have the right to receive upon conversion the amount of Securities such Holder would have received had such Holder converted each Debenture on the Record Date. In the event that such dividend or distribution is not so paid or made, the
Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the Fair Market Value of any distribution for purposes of
this Section 7.05(d) by reference to the actual or when issued trading market for any Securities, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price of the Common Stock. 

 

 -30- 








 Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders
thereof to subscribe for or purchase shares of the Company’s capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i)
are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 7.05 (and no
adjustment to the Conversion Price under this Section 7.05 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is
required) to the Conversion Price shall be made under this Section 7.05(d). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Third Supplemental Indenture, are subject to events, upon
the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution
and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed
distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the
Conversion Price under this Section 7.05 was made, (1) in the case of any such rights or warrants which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be readjusted upon such final
redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with
respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants which shall have
expired or been terminated without exercise by any holders thereof, the Conversion Price shall be readjusted as if such rights and warrants had not been issued. 
  

Notwithstanding the foregoing, in the event that the Company shall distribute rights or warrants to subscribe for additional shares of the Common Stock
(other than rights or warrants described in Section 7.05(b)), pro rata to holders of Common Stock, and in the case of the rights issued pursuant to the Company’s stockholder rights agreement in existence as of the date hereof, the Company may,
in lieu of making any adjustment pursuant to this Section 7.05(d), make proper provision (in the case of the Company’s stockholder rights agreement in existence as of the date thereof, to the extent it does not make proper provision) so that
each holder of a Debenture who converts such Debenture (or any portion thereof) after the record date for such distribution shall be entitled to receive upon such conversion, in addition to cash and, if applicable, shares of Common Stock issuable
upon such conversion (the “Conversion Shares”): (i) if such conversion occurs on or prior to the date for the distribution to the holders of such rights or warrants of separate certificates evidencing such rights or warrants (the
“Rights Distribution Date”), a number of rights or warrants equal to the number of rights or warrants a holder of Common Stock would receive if such holder held that number of shares of Common 

  

 -31- 








 
Stock equal to the product of (x) the quotient obtained by dividing the principal amount of the Debentures to be converted by such Holder by $50 and (y) the
Conversion Ratio; and (ii) if such conversion occurs after the Rights Distribution Date, a number of rights or warrants equal to the number of rights or warrants a holder of Common Stock would receive if such holder held that number of shares of
Common Stock equal to the product of (x) the quotient obtained by dividing the principal amount of the Debentures to be converted by such Holder by $50 and (y) the Conversion Ratio immediately prior to the Rights Distribution Date. 
  
 For purposes of this Section 7.05(d) and Sections 7.05(a) and (b), any
dividend or distribution to which this Section 7.05(d) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock (or both), shall be deemed instead to be (1) a dividend or
distribution of the evidences of indebtedness, assets or shares of capital stock other than such shares of Common Stock or rights or warrants (and any Conversion Price reduction required by this Section 7.05(d) with respect to such dividend or
distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Conversion Price reduction required by Sections 7.05(a) and (b) with respect to such
dividend or distribution shall then be made), except (A) the Record Date of such dividend or distribution shall be substituted as “the date fixed for the determination of stockholders entitled to receive such dividend or other
distribution” and “the date fixed for such determination” within the meaning of Sections 7.05(a) and (b) and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding at the close
of business on the date fixed for such determination” within the meaning of Section 7.05(a). 
  
 (e) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding (x) any quarterly cash dividend on
the Common Stock to the extent the aggregate cash dividend per share of Common Stock in any fiscal quarter does not exceed the greater of (A) the amount per share of Common Stock of the most recent quarterly cash dividend on the Common Stock to the
extent that such preceding quarterly dividend did not require any adjustment of the Conversion Price pursuant to this Section 7.05(e) (as adjusted to reflect subdivisions or combinations of the Common Stock), and (B) 3.75% of the arithmetic average
of the Closing Price (determined as set forth in Section 7.05(h)) during the ten Trading Days (as defined in Section 7.05(h)) immediately prior to the date of declaration of such dividend, and (y) any dividend or distribution in connection with the
liquidation, dissolution or winding up of the Company, whether voluntary or involuntary), then, in such case, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect
immediately prior to the close of business on such Record Date by a fraction of which the numerator shall be the Current Market Price of the Common Stock on the Record Date less the amount of cash so distributed (and not excluded as provided above)
applicable to one share of Common Stock and the denominator shall be such Current Market Price of the Common Stock, such reduction to be effective immediately prior to the opening of business on the day following the Record Date; provided,
however, that in the event the portion of the cash so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price of the Common Stock on the Record Date, in lieu of the foregoing adjustment, adequate
provision shall be made so that each Holder shall have the right to receive upon conversion the amount of cash such Holder would have received had such Holder converted each Debenture on the Record Date. In the event that such dividend or 

  

 -32- 








 
distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend
or distribution had not been declared. If any adjustment is required to be made as set forth in this Section 7.05(e) as a result of a distribution that is a quarterly dividend, such adjustment shall be based upon the amount by which such
distribution exceeds the amount of the quarterly cash dividend permitted to be excluded pursuant hereto. If an adjustment is required to be made as set forth in this Section 7.05(e) above as a result of a distribution that is not a quarterly
dividend, such adjustment shall be based upon the full amount of the distribution. 
  
 (f) In case a tender or exchange offer made by the Company or any Subsidiary for all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall
require the payment to stockholders of consideration per share of Common Stock having a Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive and described in a resolution of the Board of Directors) that
as of the last time (the “Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended) that exceeds the Current Market Price of the Common Stock on the Trading Day next
succeeding the Expiration Time, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the Expiration Time by a fraction of which the numerator shall
be the number of shares of Common Stock outstanding (including any tendered or exchanged shares) on the Expiration Time multiplied by the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time and the
denominator shall be the sum of (x) the Fair Market Value (determined as aforesaid) of the aggregate consideration payable to 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) on the Expiration Time and the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, such reduction to become effective immediately prior to the opening
of business on the day following the Expiration Time. In the event that the Company is obligated to purchase shares pursuant to any such tender or exchange offer, but the Company is permanently prevented by applicable law from effecting any such
purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender or exchange offer had not been made. 
  
 (g) In case of a tender or exchange offer made by a person other than the
Company or any Subsidiary for an amount which increases the offeror’s ownership of Common Stock to more than fifty percent (50%) of the Common Stock outstanding and shall involve the payment by such person of consideration per share of Common
Stock having a Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a resolution of the Board of Directors) at the last time (the “Offer Expiration Time”) tenders or
exchanges may be made pursuant to such tender or exchange offer (as it shall have been amended) that exceeds the Current Market Price of the Common Stock on the Trading Day next succeeding the Offer Expiration Time, and in which, as of the Offer
Expiration Time the Board of Directors is not recommending rejection of the offer, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in 
  

 -33- 








 
effect immediately prior to the Offer Expiration Time by a fraction of which the numerator shall be the number of shares of Common Stock outstanding
(including any tendered or exchanged shares) on the Offer Expiration Time multiplied by the Current Market Price of the Common Stock on the Trading Day next succeeding the Offer Expiration Time and the denominator shall be the sum of (x) the Fair
Market Value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not
withdrawn as of the Offer Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the “Accepted Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less
any Accepted Purchased Shares) on the Offer Expiration Time and the Current Market Price of the Common Stock on the Trading Day next succeeding the Offer Expiration Time, such reduction to become effective immediately prior to the opening of
business on the day following the Offer Expiration Time. In the event that such person is obligated to purchase shares pursuant to any such tender or exchange offer, but such person is permanently prevented by applicable law from effecting any such
purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender or exchange offer had not been made. Notwithstanding the foregoing, the adjustment
described in this Section 7.05(g) shall not be made if, as of the Offer Expiration Time, the offering documents with respect to such offer disclose a plan or intention to cause the Company to engage in any transaction described in Article 5 of the
Base Indenture. 
  
 (h) For purposes of this Section 7.05, the
following terms shall have the meaning indicated: 
  
 (1) “Closing Price” with respect to any securities on any day shall mean the closing sale price regular way on such day or, in case no such sale takes place on such day, the average of the reported closing bid and asked
prices, regular way, in each case on the New York Stock Exchange, or, if such security is not listed or admitted to trading on such Exchange, on the principal national security exchange or quotation system on which such security is quoted or listed
or admitted to trading, or, if not quoted or listed or admitted to trading on any national securities exchange or quotation system, the average of the closing bid and asked prices of such security on the over-the-counter market on the day in
question as reported by the National Quotation Bureau Incorporated, or a similar generally accepted reporting service, or if not so available, in such manner as furnished by any New York Stock Exchange member firm selected from time to time by the
Board of Directors for that purpose, or a price determined in good faith by the Board of Directors or, to the extent permitted by applicable law, a duly authorized committee thereof, whose determination shall be conclusive. 
  
 (2) “Current Market Price” shall mean the
average of the daily Closing Prices per share of Common Stock for the ten consecutive Trading Days immediately prior to the date in question; provided, however, that (1) if the “ex” date (as hereinafter defined) for any event
(other than the issuance or distribution or Change of Control requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 7.05(a), (b), (c), (d), (e), (f) or (g) occurs during such ten consecutive Trading
Days, the Closing Price for each Trading Day prior to the “ex” date 

  

 -34- 








 
for such other event shall be adjusted by multiplying such Closing Price by the same fraction by which the Conversion Price is so required to be adjusted as
a result of such other event, (2) if the “ex” date for any event (other than the issuance, distribution or Change of Control requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 7.05(a), (b),
(c), (d), (e), (f) or (g) occurs on or after the “ex” date for the issuance or distribution requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the “ex” date for such
other event shall be adjusted by multiplying such Closing Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event, and (3) if the “ex” date for the issuance,
distribution or Change of Control requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to clause (1) or (2) of this proviso, the Closing Price for each Trading Day on or after such
“ex” date shall be adjusted by adding thereto the amount of any cash and the fair market value (as determined by the Board of Directors or, to the extent permitted by applicable law, a duly authorized committee thereof in a manner
consistent with any determination of such value for purposes of Section 7.05(d), (f) or (g), whose determination shall be conclusive and described in a resolution of the Board of Directors or such duly authorized committee thereof, as the case may
be) of the evidences of indebtedness, shares of capital stock or assets being distributed applicable to one share of Common Stock as of the close of business on the day before such “ex” date. For purposes of any computation under Section
7.05(f) or (g), the Current Market Price of the Common Stock on any date shall be deemed to be the average of the daily Closing Prices per share of Common Stock for such day and the next two succeeding Trading Days; provided, however,
that if the “ex” date for any event (other than the tender or exchange offer requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 7.05(a), (b), (c), (d), (e), (f) or (g) occurs on or after the
Expiration Time or Offer Expiration Time, as the case may be, for the tender or exchange offer requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the “ex” date for such other
event shall be adjusted by multiplying such Closing Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term “ex” date,
(1) when used with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way on the relevant exchange or in the relevant market from which the Closing Price was obtained without the right to receive
such issuance or distribution, (2) when used with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades regular way on such exchange or in such market after the time at which such
subdivision or combination becomes effective, and (3) when used with respect to any tender or exchange offer means the first date on which the Common Stock trades regular way on such exchange or in such market after the Offer Expiration Time of such
offer. 
  
 (3) “Fair Market
Value” shall mean the amount which a willing buyer would pay a willing seller in an arm’s-length transaction. 
  
 (4) “Record Date” shall mean, with respect to any dividend, distribution or other transaction or event in which the
holders of Common Stock have 

  

 -35- 








 
the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into
any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or
otherwise). 
  
 (i) The Company may make such reductions in the
Conversion Price, in addition to those required by Sections 7.05 (a), (b), (c), (d), (e), (f) or (g) as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common
Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes. 
  
 To the extent permitted by applicable law, the Company from time to time may reduce the Conversion Price by any amount for any period of time if the
period is at least twenty (20) days, the reduction is irrevocable during the period and the Board of Directors shall have made a determination that such reduction would be in the best interests of the Company, which determination shall be
conclusive. Whenever the Conversion Price is reduced pursuant to the preceding sentence, the Company shall mail to Holders of record of the Debentures a notice of the reduction at least fifteen (15) days prior to the date the reduced Conversion
Price takes effect, and such notice shall state the reduced Conversion Price and the period during which it will be in effect. 
  
 (A) Calculation Methodology. No adjustment in the Conversion Price shall be required unless such adjustment would require an increase or decrease
of at least one percent (1%) in such price; provided, however, that any adjustments which by reason of this Section 7.05(j) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All
calculations under this Article 7 shall be made by the Company and shall be made to the nearest cent or to the nearest one-hundredth (1/100) of a share, as the case may be. No adjustment need be made for rights to purchase Common Stock pursuant to a
Company plan for reinvestment of dividends or interest. To the extent the Debentures become convertible into cash, assets, property or securities (other than capital stock of the Company), no adjustment need be made thereafter as to the cash,
assets, property or such securities. Interest will not accrue on the cash. 
  
 (B) When No Adjustment Required. 
  
 The applicable Conversion Price will not be adjusted: 
  
 (1) if holders of the Trust PIERS or, following distribution of the Debentures to the holders of the Trust PIERS, the Debentures are
entitled to participate in a transaction otherwise requiring adjustment pursuant to Section 7.05(a), (b), (d), (e), (f) or (g); 
  
 (2) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or
interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan; 
  

 -36- 








 (3) upon the issuance of any shares of Common Stock or options, rights or warrants to
purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries; 
  
 (4) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable or
exchangeable or convertible security outstanding as of June 13, 2003; 
  
 (5) for a change in the par value of the Company’s common stock, other than any such change that occurred in connection with an event requiring adjustment under Section 7.05(c) hereof; 
  
 (6) for accrued and unpaid interest, including contingent
interest; or 
  
 (7) for the issuance of rights
under any shareholder rights plan. 
  
 (j) In any case in which
this Section 7.05 provides that an adjustment shall become effective immediately after a Record Date for an event, the Company may defer until the occurrence of such event (i) issuing to the Holder of any Debenture converted after such Record Date
and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such
adjustment and (ii) paying to such Holder any amount in cash in lieu of any fraction pursuant to Section 7.03. 
  
 (k) For purposes of this Section 7.05, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the
Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the
Company. 
  
 SECTION 7.06 Effect of Reclassification,
Consolidation, Merger or Sale. If any of the following events occur, namely (i) any reclassification or change of the outstanding shares of Common Stock (other than a subdivision or combination to which Section 7.05(c) applies), (ii) any
consolidation, merger or combination of the Company with another corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for
such Common Stock, or (iii) any sale or conveyance of the properties and assets of the Company as, or substantially as, an entirety to any other Person as a result of which holders of Common Stock shall be entitled to receive stock, securities or
other property or assets (including cash) with respect to or in exchange for such Common Stock, then the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply
with the Trust Indenture Act as in force at the date of execution of such supplemental indenture) providing that the Debentures shall be convertible into the kind and amount of shares of stock and other securities or property or assets (including
cash) receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance by a holder of a number of shares of Common Stock, if any, issuable upon conversion of such Debentures (assuming, for such 

  

 -37- 








 
purposes, a sufficient number of authorized shares of Common Stock available to convert all such Debentures) immediately prior to such reclassification,
change, consolidation, merger, combination, sale or conveyance assuming such holder of Common Stock did not exercise his rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such consolidation,
merger, combination, sale or conveyance (provided that, if the kind or amount of securities, cash or other property receivable upon such consolidation, merger, combination, sale or conveyance is not the same for each share of Common Stock in
respect of which such rights of election shall not have been exercised (“nonelecting share”)), then for the purposes of this Section 7.06 the kind and amount of securities, cash or other property receivable upon such consolidation,
merger, combination, sale or conveyance for each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares. Such supplemental indenture shall provide for adjustments which shall be
as nearly equivalent as may be practicable to the adjustments provided for in this Article. A Holder may convert Debentures at any time from and after the date which is 15 days prior to the anticipated effective date of a transaction of the type
described in clause (i), (ii) or (iii) above until 15 days after the effective date of such transaction. 
  
 The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder of Debentures, at its address appearing on the
Debenture register provided for in Section 2.07 of the Base Indenture, within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 
  
 The above provisions of this Section shall similarly apply to successive
reclassifications, changes, consolidations, mergers, combinations, sales and conveyances. 
  
 If this Section 7.06 applies to any event or occurrence, Section 7.05 shall not apply. 
  
 SECTION 7.07 Taxes on Shares Issued. The issue of stock certificates on conversions of Debentures shall be made without charge to the converting
Holder for any tax in respect of the issue thereof. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of stock or the payment of cash upon conversion in any
name other than that of the Holder of any Debenture converted, and the Company shall not be required to issue or deliver any such stock certificate or pay such cash amount unless and until the person or persons requesting the issue thereof shall
have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 
  
 SECTION 7.08 Reservation of Shares; Shares to Be Fully Paid; Compliance with Governmental Requirements; Listing of Common Stock. The Company shall
provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for the conversion of the Debentures from time to time to the extent such Debentures presented
for conversion are convertible in Common Stock. 
  
 Before taking
any action which would cause an adjustment reducing the Conversion Price below the then par value, if any, of the Conversion Shares, the Company will take all corporate action which may, in the opinion of its counsel, be necessary in order that the
Company may validly and legally issue Conversion Shares at such adjusted Conversion Price. 
  

 -38- 








 The Company covenants that all Conversion Shares will upon issue be fully paid and non-assessable by the
Company and free from all taxes, liens and charges with respect to the issue thereof. 
  
 The Company covenants that if any Conversion Shares require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the
Company will in good faith and as expeditiously as possible endeavor to secure such registration or approval, as the case may be. 
  
 The Company further covenants that if at any time the Common Stock shall be listed on the New York Stock Exchange or any other national securities
exchange or automated quotation system the Company will, if permitted by the rules of such exchange or automated quotation system, list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system,
all Common Stock issuable upon conversion of the Debentures; provided, however, that if rules of such exchange or automated quotation system permit the Company to defer the listing of such Common Stock until the first conversion of the
Debentures pursuant to which Common Stock is issuable in accordance with the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Debentures in accordance with the requirements of such
exchange or automated quotation system at such time. 
  
 SECTION
7.09 Responsibility of Trustee. 
  
 (a) The Trustee and
any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Debentures to determine the Conversion Ratio, the Conversion Price or whether any facts exist which may require any adjustment of the Conversion
Price or the Conversion Ratio, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same.
The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, which may at any time be issued or delivered upon the
conversion of any Debenture; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver
cash and, if applicable, any shares of Common Stock or stock certificates or other securities or property upon the surrender of any Debenture for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the
Company contained in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental
indenture entered into pursuant to Section 7.06 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Debentures after any event referred to in such
Section 7.06 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01 of the Base Indenture, may accept as conclusive evidence of the correctness of any such provisions, and 

  

 -39- 








 
shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of
any such supplemental indenture) with respect thereto.

 Exhibit A 
  

Principal Amount: $ 
 No. 1 
  
 Omnicare, Inc.

  
 SERIES B 4.00% JUNIOR SUBORDINATED CONVERTIBLE DEBENTURE

 DUE JUNE 15, 2033 
  
 Omnicare, Inc., a Delaware corporation (the “Company,” which term includes any successor Person under the Indenture hereinafter referred to),
for value received, hereby promises to pay to JPMorgan Chase Bank, as Property Trustee for Omnicare Capital Trust I, or registered assigns, the principal sum of             Dollars on
($            ) June 15, 2033 (the “Maturity Date”), unless previously redeemed, and to pay interest on the outstanding principal amount hereof from June 13, 2003, or from the
most recent interest payment date (each such date, an “Interest Payment Date”) to which interest has been paid or duly provided for, quarterly (subject to deferral as set forth herein) in arrears on March 15, June 15, September 15 and
December 15 of each year, commencing March 15, 2005, at the rate of 4.00% per annum until the principal hereof shall have become due and payable, and on any overdue principal and (without duplication and to the extent that payment of such interest
is enforceable under applicable law) on any overdue installment of interest at the same rate per annum compounded quarterly. The amount of interest payable for any full quarterly interest period shall be computed on the basis of a 360-day year of
twelve 30-day months and, for any period shorter than a full 90-day quarterly interest period will be computed on the basis of a 30-day month, and for any period less than a full calendar month, the number of days elapsed in such month. In the event
that any Interest Payment Date is not a Business Day, then the payment 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
next succeeding Business Day falls in the next calendar year, then such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. Pursuant to the Indenture, in certain
circumstances the Company will be required to pay Compounded Interest (as defined in the Indenture) with respect to this Debenture. 
  
 The Company shall pay contingent interest to the Holders during any quarterly period (a “Contingent Interest Period”) from March 15 to June 14,
June 15 to September 14, September 15 to December 14 and December 15 to March 14, commencing with the Contingent Interest Period beginning June 15, 2009, if the average of the Trading Prices of the Trust PIERS (or of the Debentures following any
distribution of the Debentures to the holders of the Trust PIERS) for the five consecutive Trading Days ending on the second trading day preceding such Contingent Interest Period (the “Five Trading Day Period”) equals 115% or more of the
stated liquidation amount of the Trust PIERS or principal amount of the Debentures, as the case may be. The amount of contingent interest payable in respect of any Contingent Interest Period will equal 0.125% of the average Trading Price of the
Trust PIERS (or the Debentures, as the case 








 
may be) over the Five Trading Day Period preceding such Contingent Interest Period. Contingent interest shall only be paid in cash. Contingent interest, if
any, will accrue and be payable to Holders in the same manner as regular cash interest as provided above. Regular cash interest will continue to accrue at the rate of 4.00% per annum on the principal amount of the Debentures whether or not
contingent interest is paid. 
  
 The interest installment so
payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Debenture is registered at the close of business on the day next preceding the Interest
Payment Date. If the Trust PIERS do not remain in book-entry only form and the Debentures are not in the form of a Global Security, the Company will have the right to select record dates, which must be at least one Business Day before an Interest
Payment Date (whether or not a Business Day), as the case may be, immediately preceding such Interest Payment Date. Any such interest installment, including contingent interest, not punctually paid or duly provided for (excluding installments of
interest (other than contingent interest) that are subject to an Extension Period) shall forthwith cease to be payable to the Holders on such Regular Record Date and shall be paid to the Person in whose name this Debenture is registered at the close
of business on a special record date to be fixed by the Company for the payment of such defaulted interest, provided that no special record date shall be less than 10 days prior to the related payment date for such defaulted interest or may be paid
at any time in any other lawful manner deemed practicable by the Trustee after notice thereof by the Company to the Trustee. 
  
 The principal of and interest (including contingent interest, if any) on this Debenture shall be payable at the office or agency of the Company maintained
for that purpose. 
  
 The indebtedness evidenced by this Debenture
is, to the extent provided in the Indenture, subordinate and junior in right of payment to the prior payment in full of all Senior Indebtedness, and this Debenture is issued subject to the provisions of the Indenture with respect thereto. 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 his or her behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the
subordination so provided and (c) appoints the Trustee his or her attorney-in-fact for any and all such purposes. Each holder hereof, by his or her acceptance hereof, hereby waives all notice of the acceptance of the subordination provisions
contained herein and in the Indenture by each holder of Senior Indebtedness, whether now outstanding or hereafter incurred, and waives reliance by each such holder upon said provisions. 
  
 This Debenture shall not be entitled to any benefit under the Indenture hereinafter referred to, be valid or become
obligatory for any purpose until the Certificate of Authentication hereon shall have been signed by or on behalf of the Trustee. 
  
 This Debenture is one of the Debentures of the Company (herein sometimes referred to as the “Debentures”), specified in the Indenture, all
issued or to be 

  

 2 








 
issued under and pursuant to an Indenture, dated as of June 13, 2003 (the “Base Indenture”), as supplemented by that Third Supplemental Indenture
dated March     , 2005 (the “Third Supplemental Indenture” and together with the Base Indenture, the “Indenture”), duly executed and delivered between the Company and SunTrust Bank, as Trustee (the
“Trustee”), to which Indenture reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the holders of the Debentures. Capitalized terms
used but not defined herein shall have the meanings given to them in the Indenture. 
  
 The provisions of this Debenture are continued on the reverse side hereof and such provisions shall for all purposes have the same effect as though fully set forth at this place.

 (REVERSE OF DEBENTURE) 
  
 This Debenture is one of the Debentures of the Company (herein sometimes referred to as the “Debentures”),
specified in the Indenture, all issued or to be issued under and pursuant to an Indenture, dated as of June 13, 2003 (the “Base Indenture”), as supplemented by that Third Supplemental Indenture dated as of March      ,
2005 (the “Third Supplemental Indenture” and together with the Base Indenture, the “Indenture”), duly executed and delivered between the Company and SunTrust Bank, as Trustee (the “Trustee”), to which Indenture
reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the holders of the Debentures. Capitalized terms used but not defined herein shall have
the meanings given to them in the Indenture. 
  
 1.
Redemption. Upon the occurrence and continuation of a Special Event, the Company shall have the right, at any time following the occurrence of such Special Event, to redeem this Debenture in whole (but not in part) at a purchase price equal
to 100% of the principal amount to be redeemed, plus accrued and unpaid interest, including contingent interest, if any, to the date of redemption (the “Redemption Price”). 
  
 In addition, the Company shall have the right to redeem the Debentures, in whole or in part, on one or more occasions at any
time on or after June 15, 2009, upon not less than 30 days and not more than 60 days’ notice, at the Redemption Price. 
  
 The Redemption Price shall be paid prior to 12:00 noon, New York time, on the date of such redemption or at such earlier time as the Company determines;
provided, that the Company shall deposit with the Trustee an amount sufficient to pay the Redemption Price by 12:00 noon, New York time on the date such Redemption Price is to be paid. Any redemption pursuant to this paragraph will be made
upon not less than 30 days nor more than 60 days notice to the Holder. Notwithstanding the foregoing, the Holders of at least a majority in aggregate principal amount of the Debentures may agree to reduce the notice period to not less than five
days. If the Debentures are only partially redeemed by the Company pursuant to an optional redemption described in the preceding paragraph, the Trustee will select the Debentures to be redeemed among the Holders of the Debentures in compliance with
the requirements of the principal national securities exchange, if any, on which the Debentures are listed or, if the Debentures are not so listed, on a pro rata basis, by lot or in accordance with any other method the Trustee considers fair and
appropriate. 
  
 2. Offer to Repurchase Upon Change of
Control. If a Change of Control shall occur, each Holder of Debentures will have the right to require the Company to repurchase all or any part of that Holder’s Debentures pursuant to a Change of Control offer (the “Change of Control
Offer”) at a purchase price equal to 100% of the aggregate principal amount of Debentures repurchased plus accrued and unpaid interest (including contingent interest, if any) on the Debentures repurchased, to the Change of Control Payment Date.
Within 30 days following any Change of Control, the Company will mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture. On the Change of Control Payment Date, the 

  

 5 








 
Company will, to the extent lawful: (i) accept for payment all Debentures or portions of Debentures properly tendered pursuant to the Change of Control
Offer; (ii) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Debentures or portions of Debentures properly tendered; and (iii) deliver or cause to be delivered to the Trustee the Debentures properly
accepted together with an Officers’ Certificate stating the aggregate principal amount of Debentures or portions of Debentures being purchased by the Company. The paying agent will promptly mail to each Holder of Debentures properly tendered
the Change of Control Payment for such Debentures, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Debenture equal in principal amount to any unpurchased portion of the Debentures
surrendered, if any; provided, that each new Debenture will be in a principal amount of $50 or an integral multiple of $50. 
  
 3. Conversion. (a) Subject to and upon compliance with the provisions of Article VII of the Third Supplemental Indenture, the Debentures are
convertible, at the option of the Holder, at any time on and after the occurrence of any of the events described in paragraph (b) below, and before 5:00 pm, New York, New York time, on the Business Day immediately preceding the date of repayment of
such Debentures, whether at Stated Maturity or upon redemption, into fully paid and nonassessable shares of Common Stock at an initial Conversion Ratio of 1.2248 shares of Common Stock for each $50 in aggregate principal amount of Debentures,
subject to adjustment as described in such Article VII. A Holder may convert any portion of the principal amount of such Holder’s Debentures into (x) a cash amount equal to the lesser of (i) the aggregate principal amount of the Debentures to
be converted or (ii) the Applicable Stock Price multiplied by the Conversion Ratio (multiplied by the aggregate principal amount of Debentures to be converted divided by 50) and (y) if the product of the Applicable Stock Price and the Conversion
Ratio (multiplied by the aggregate principal amount of Debentures to be converted divided by 50) exceeds the aggregate principal amount of Debentures to be converted, that number of fully paid and nonassessable shares of Common Stock (calculated as
to each conversion to the nearest 1/100th of a share) equal to (i) the aggregate principal amount of Debentures to be converted divided by $50 and multiplied by (ii) (A) the Conversion Ratio minus (B) $50 divided by the Applicable Stock Price.
Settlement in cash and, if applicable, shares of Common Stock will occur on the second Trading Day following the final trading day of the Cash Settlement Averaging Period. Such day will be the 22nd Trading Day following the Property Trustee’s
receipt of a Holder’s conversion notice submitted by the holder of Trust PIERS (assuming such holder has satisfied all conversion requirements, including the valid delivery of the conversion notice), unless (i) the conversion is in connection
with a redemption, in which case the settlement day will be the redemption date or (ii) such holder of Trust PIERS submits a conversion notice during the period beginning 25 Trading Days preceding the maturity date and ending one Trading Day
preceding the maturity date, in which case the settlement day will be the maturity date. 
  
 (b) A Holder’s right to convert its Debentures will arise only upon the occurrence of any of the following: 
  

 6 








 (i) Conversion Rights Based on Common Stock Price. If, as of the last day of any
calendar quarter beginning with the quarter ending March 31, 2005, the Closing Sale Price of the Common Stock on each of at least 20 Trading Days in a period of 30 consecutive Trading Days ending on the last Trading Day of such calendar quarter is
more than 130% of the Conversion Price in effect on the last day of such quarter, then on and after the first day of the following calendar quarter (and only during such following calendar quarter), Holders may surrender their Debentures for
conversion into shares of Common Stock at any time at their option until 5:00 p.m., New York time, on the Business Day immediately preceding the Stated Maturity or earlier Redemption Date. 
  
 (ii) Conversion Rights Based on Notice of Redemption.
A Holder may surrender for conversion a Debenture that has been called for redemption at any time prior to 5:00 p.m., New York time, on the day that is two Business Days immediately preceding the date of redemption, even if such Debenture is not
otherwise convertible at that time. 
  
 (iii)
Conversion Rights Based on Trust PIERS Trading Price. Holders may also surrender a Debenture for conversion during the five-Business-Day period following any 10-consecutive-Trading-Day period in which the average of the Trading Prices for the
Trust PIERS (or, if the Debentures have been distributed to the holders of the Trust PIERS, the average of the Trading Prices for the Debentures) for such 10-Trading-Day period was less than a Specified Trigger Percentage (as defined below) of the
average of the Conversion Values for the Trust PIERS or the Debentures, as the case may be, for each day during such period. The “Specified Trigger Percentage” will be 105% for any 10-Trading-Day period that ends before June 15, 2028 and
98% for any 10-Trading-Day period ending after that date. 
  
 (iv) Conversion Rights Based on Occurrence of Certain Corporate Transactions. 
  
 If: 
  

	 	(1)	the Company shall distribute to all holders of its Common Stock rights or warrants entitling them to purchase, for a period expiring within 60 days of the date of any such
distribution, Common Stock at a price per share less than the Trading Price of the Common Stock on the Trading Day immediately preceding the date of the announcement of such distribution; 

  

	 	(2)	the Company elects to distribute to all holders of its Common Stock cash or other assets, debt securities or rights or warrants to purchase its securities, which distribution has a
per share value (as determined by the Company’s Board of Directors) exceeding 10% of the Trading Price of Common Stock on the Business Day preceding the declaration date for the distribution; or 

  

 7 









	 	(3)	a Change of Control occurs but holders of Debentures do not have the right to require the Company to repurchase their Debentures as a result of such Change of Control because either
(1) the trading price of Common Stock during the period described in the definition of “Change of Control” set forth in the Indenture equals or exceeds the level specified in clause (x) of such definition or (2) the consideration received
in such Change of Control consists of common stock that is freely tradable and the Trust PIERS (or the Debentures following the distribution of the Debentures to the holders of the Trust PIERS) become convertible into that common stock (as described
in clause (y) of the definition of “Change of Control” set forth in the Indenture), 

  
 then the Company shall be required to notify the Holders of the Debentures at least 20 days prior to the ex-dividend date for the distribution or within
30 days of the occurrence of the Change of Control, as the case may be. Once the Company has given such notice, Holders may surrender their Debentures for conversion at any time until either (a) the earlier of the close of business on the Business
Day immediately prior to the ex-dividend date and the date on which the Company announces that the distribution will not take place, in the case of a distribution or (b) 30 days after the date of the notice of the Change of Control, in the case of a
Change of Control. A Holder will not have the right to convert Debentures as a result of a distribution if such Holder has rights to participate, or will have such rights, in the distribution without conversion. 
  
 If any of the following events occur, namely (i) any
reclassification or change of the outstanding shares of Common Stock (other than a subdivision or combination to which Section 7.05(c) of the Third Supplemental Indenture applies), (ii) any consolidation, merger or combination of the Company with
another Person as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, or (iii) any sale or conveyance of the
properties and assets of the Company as, or substantially as, an entirety to any other Person as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or
in exchange for such Common Stock, then the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of
execution of such supplemental indenture) providing that the Debentures shall be convertible into the kind and amount of shares of stock and other securities or property or assets (including cash) receivable upon such reclassification, change,
consolidation, merger, combination, sale or conveyance by a holder of a number of shares of Common Stock, if any, issuable upon conversion of such Debentures (assuming, for such purposes, a sufficient number of authorized shares of Common Stock
available to convert all such Debentures) immediately prior to such reclassification, change, consolidation, merger, 

  

 8 








 
combination, sale or conveyance assuming such holder of Common Stock did not exercise his rights of election, if any, as to the kind or amount of securities,
cash or other property receivable upon such consolidation, merger, combination, sale or conveyance (provided that, if the kind or amount of securities, cash or other property receivable upon such consolidation, merger, combination, sale or
conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised (“nonelecting share”)), then for the purposes of this paragraph the kind and amount of securities,
cash or other property receivable upon such consolidation, merger, combination, sale or conveyance for each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares. Such
supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in Article VII of the Third Supplemental Indenture. A Holder may convert Debentures at any time from and
after the date which is 15 days prior to the anticipated effective date of a transaction of the type described in clause (i), (ii) or (iii) above until 15 days after the effective date of such transaction. 
  
 (c) To convert all or a portion of the Debentures, the
Holder thereof shall deliver to the Conversion Agent an irrevocable written notice of conversion in the form provided hereon (or such other notice which is acceptable to the Company (the “Conversion Request”) setting forth the principal
amount of Debentures to be converted, together with the name or names, if other than the Holder, in which the shares of Common Stock should be issued, and shall be accompanied by transfer taxes if required pursuant to Section 7.07 of the Third
Supplemental Indenture and, if such Debentures are in certificate form, surrender to the Conversion Agent the Debentures to be converted, duly endorsed or assigned to the Company or in blank. In addition, a Holder of Trust PIERS may exercise its

the Applicable Stock Price thereof to the Holder of Debentures.

 10 








 
majority in aggregate principal amount of the Debentures at the time outstanding, as defined in the Indenture, to execute supplemental indentures for the
purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of modifying in any manner the rights of the Holders of the Debentures; provided, however, that no such supplemental
indenture shall, without the consent of each Holder of Debentures then outstanding and affected thereby, (i) change the Stated Maturity of any Debenture, or reduce the principal amount of, or any installment of principal of or rate of interest on,
the Debentures or any premium payable upon redemption thereof; (ii) reduce the rate or extend the time of payment of interest; (iii) modify any of the provisions of Article VI of the Indenture relating to waiver of past defaults and rights of
Holders to receive payment or modify any of the foregoing provisions except to increase the percentage Debentures required for such actions to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of
the Holders affected thereby; (iv) make the principal of, or interest payment on, the Debentures payable in any coin or currency other than that provided in the Indenture; (v) change the place of payment where the Debentures or any interest payment
thereon is payable; (vi) impair or affect the right of any Holder of Debentures to institute suit for the payment of the Debentures as provided in the Indenture; (vii) reduce the percentage of the principal amount of the Debentures required to

Holders and owners of this Debenture and of any Debenture issued in exchange herefor or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this
Debenture. 
  
 6. No Impairment. No reference herein to the
Indenture and no provision of this Debenture or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest, including contingent interest, if any, on this Debenture

 7. Extension of Interest Payment Period. So long as the Company is not in Default in the payment of interest, including contingent interest, if any, on the Debentures, the Company shall have the right, at any
time and from time to time during the term of the Debentures, to defer payments of interest, other than contingent interest, by extending the interest payment period of such Debentures for a period not exceeding 20 consecutive quarterly periods,
including the first such quarterly period during such extension period (an “Extension Period”), during which Extension Period no interest (other than contingent interest) shall be due and payable; provided, that no Extension Period
shall extend beyond the Stated Maturity or, with respect to any Debentures called for redemption, the Redemption Date with respect to such Debentures. To the extent 

  

 11 








 
permitted by applicable law, interest, the payment of which has been deferred because of the extension of the interest payment period pursuant to Section
6.01 of the Third Supplemental Indenture, will bear interest thereon at the Coupon Rate compounded quarterly for each quarterly period of the Extension Period (“Compounded Interest”). At the end of the Extension Period, which is an
Interest Payment Date, the Company shall pay all interest accrued and unpaid on the Debentures (together, “Deferred Interest”) that shall be payable to Holders on the Regular Record Date immediately preceding the end of the Extension
Period. Before the termination of any Extension Period, the Company may further defer payments of interest (other than contingent interest) by further extending such period, provided that such period, together with all such previous and further
extensions within such Extension Period, shall not exceed 20 consecutive quarterly periods, including the first such quarterly period during such Extension Period, or extend beyond the Stated Maturity of the Debentures or, with respect to any
Debentures called for redemption, the Redemption Date with respect to such Debentures. If any Extension Period ends on a day that is not an Interest Payment Date, then on or prior to the last day of such Extension Period, the Company shall deposit
with the Trustee the full amount of unpaid interest that has accrued on the Debentures through the last Interest Payment Date that falls prior to the last day of the Extension Period, and on the Interest Payment Date following the last day of the
Extension Period, all unpaid interest accrued on the Debentures through that following Interest Payment Date will be due and payable unless the Company further extends the Extension Period to a later date, in which case the amounts deposited with
the Trustee shall be returned to the Company. Upon the termination of any Extension Period and the payment of all Deferred Interest then due, the Company may commence a new Extension Period, subject to the foregoing requirements. No interest (other
than contingent interest) shall be due and payable during an Extension Period, except at the end thereof, but the Company may prepay at any time all or any portion of the interest accrued during an Extension Period. The payment of contingent
interest may not, under any circumstances, be subject to an Extension Period.

securities convertible or exercisable for the Company’s Common Stock, in satisfaction of the Company’s obligations under an acquisition transaction that the Company has entered into prior to the beginning of an Extension Period, in an

repurchases are made in connection with the satisfaction of indemnification obligations of the sellers of such businesses);

 if at such time (i) an event has occurred that with the giving of notice or the lapse of
time, or both, would constitute an Event of Default and the Company has not taken reasonable steps to cure such event, (ii) the Company shall be in default with respect to its payment obligations under the Trust PIERS Guarantee or (iii) the Company
shall have given notice of its intention to begin an Extension Period pursuant to Section 6.01 of the Third Supplemental Indenture and has not rescinded the notice, or any such Extension Period shall have commenced and be continuing.
