person in whose name such Trust Securities are registered on the original record date, and such defaulted Distribution will instead be payable to the person in whose name such Trust Securities are registered on the special record date to be fixed by
the Company for the payment of such defaulted Distribution, provided that no special record date shall be less than 10 days prior to the related payment date for such defaulted Distribution 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. 
  
 (e) If the Company exercises its rights to an Extension Period with respect to the Convertible Debentures, Distributions (other than
Contingent Distributions) on the Trust PIERS shall be deferred for a period equal to the Extension Period. The payment of Contingent Distributions may not, under any circumstances, be subject to an Extension Period. 
  
 (f) Interest, including contingent interest, on the
Convertible Debentures not paid on the scheduled payment date will accrue and compound quarterly, to the extent permitted by law, at the applicable interest rate, and, as a result, Distributions and Contingent Distributions on the Trust PIERS will
accumulate and compound quarterly, to the extent permitted by law, at the applicable Distribution rate. 
  
 SECTION 4.02 Redemption. 
  
 (a) On each Redemption Date with respect to the Convertible Debentures, whether at the stated maturity of the Convertible Debentures or
upon earlier redemption as provided in the Convertible Debentures and the Subordinated Indenture, including pursuant to a Special Event, the Trust will be required to redeem a Like Amount of Trust Securities at the Redemption Price. Trust Securities
shall not be redeemed unless a Like Amount of Convertible Debentures are contemporaneously redeemed in accordance with the Subordinated Indenture. Any notice of redemption will be irrevocable. 
  
 (b) Notice of redemption shall be given by the Property
Trustee by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date to each Holder of Trust Securities to be redeemed, at such Holder’s address appearing in the Securities Register.
Notwithstanding the foregoing, the Holders of at least a majority in aggregate Liquidation Amount of the Trust PIERS may agree to reduce the notice period to not less than five days pursuant to Section 10.02(c) hereof. All notices of redemption
shall state: 
  
 (A) the Redemption Date;

  
 (B) the Redemption Price; 
  

 17 

 (C) the CUSIP number; 
  
 (D) if less than all the Outstanding Trust Securities are to be redeemed, the identification and total
Liquidation Amount of the Trust Securities to be redeemed; 
  
 (E) that on the Redemption Date the Redemption Price will become due and payable upon each such Trust Security to be redeemed and that Distributions thereon will cease to accrue on and after such date, except as
provided in Section 4.02(d); 
  
 (F) the place
where the Trust Securities are to be surrendered for the payment of the Redemption Price; and 
  
 (G) the matters set forth in Section 4.03 of the Second Supplemental Indenture to the Subordinated Indenture. 
  
 The Trust in issuing the Trust Securities may use “CUSIP” numbers
(if then generally in use), and, if so, the Property Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Trust Securities or as contained in any notice of a redemption and related materials. 
  
 (c) The Trust Securities redeemed on each Redemption Date shall be redeemed at the Redemption Price with the proceeds from the
contemporaneous redemption of Convertible Debentures. Redemptions of the Trust Securities shall be made and the Redemption Price shall be deemed payable on each Redemption Date only to the extent that the Trust has funds legally and immediately
available in the Payment Account for the payment of such Redemption Price. 
  
 (d) If the Property Trustee gives a notice of redemption in respect of any Trust PIERS, then, by 12:00 noon New York time, on the Redemption Date, to the extent funds are legally available, the Property Trustee will,
so long as the Trust PIERS are in book-entry only form, irrevocably deposit with the Clearing Agency for the Trust PIERS funds sufficient to pay the applicable Redemption Price. If the Trust PIERS are no longer represented by one or more global
certificates, the Property Trustee, to the extent funds are legally available, shall irrevocably deposit with the Paying Agent funds sufficient to pay the applicable Redemption Price and will give the Paying Agent irrevocable instructions to pay the
Redemption Price to the Holders thereof upon surrender of their Trust PIERS Certificates. Notwithstanding the foregoing, Distributions and Contingent Distributions, if any, payable on or prior to the Redemption Date for any Trust Securities called
for redemption shall be payable to the Holders of such Trust Securities as they appear on the Securities Register for the Trust Securities on the relevant record dates for the related Distribution Dates. If notice of redemption shall have been given
and funds deposited as required, then upon the date of such deposit, all rights of Holders holding Trust Securities so called for redemption will cease, except (i) the right of such Holders to receive the Redemption Price, but without interest on
such Redemption Price; and (ii) the right of the Holders to cause the Conversion Agent to convert the Trust Securities. In addition, (x) such Trust Securities will cease to be Outstanding; (y) the Clearing Agency for the Trust PIERS or its nominee,
as the registered Holder of the Book-Entry Trust PIERS Certificate, shall receive a registered global certificate or certificates representing the Convertible Debentures to be delivered upon such Distribution with respect to Trust PIERS held by the
Clearing Agency or its nominee; and (z) any Trust Securities Certificates not held by the Clearing Agency for the Trust PIERS or its nominee as specified in clause (y) of this sentence above will be deemed to represent Convertible Debentures having
a principal amount equal to the stated Liquidation Amount of the Trust Securities represented thereby and bearing accrued and unpaid interest in an amount equal to the accumulated and unpaid Distributions on such Trust Securities until the
Redemption Date. In the event 

  

 18 

 
that any date on which any Redemption Price is payable is not a Business Day, then payment of the Redemption Price payable on such date shall be made on the
next succeeding day which is a Business Day (and without any Distribution or other payment in respect of any such delay) except that, if such Business Day is in the next succeeding calendar year, payment of such Redemption Price shall be made on the
immediately preceding Business Day, in each case, with the same force and effect as if made on such date. In the event that payment of the Redemption Price in respect of Trust Securities is improperly withheld or refused and not paid either by the
Trust or by the Depositor pursuant to the Guarantee, Distributions including Contingent Distributions, if any, on such Trust Securities will continue to accrue at the then-applicable rate, from such Redemption Date originally established by the
Trust for such Trust PIERS to the date such Redemption Price is actually paid, in which case the actual payment date shall be the date fixed for redemption for purposes of calculating the Redemption Price. 
  
 (e) Subject to Section 4.02, if less than all the
Outstanding Trust Securities are to be redeemed on a Redemption Date, then the aggregate Liquidation Amount of Trust Securities to be redeemed shall be allocated on a pro rata basis (based on Liquidation Amounts) among the Common Securities and the
Trust PIERS. The particular Trust PIERS to be redeemed shall be selected on a pro rata basis (based on Liquidation Amounts) not more than 60 days prior to the Redemption Date by the Property Trustee from the Outstanding Trust PIERS not previously
called for redemption, by such method (including, without limitation, by lot) as the Property Trustee shall deem fair and appropriate and which may provide for the selection for a redemption of portions equal to the Liquidation Amount or integral
multiple thereof) of the Liquidation Amount of Trust PIERS of a denomination larger than such Liquidation Amount; provided, however, that before undertaking redemption of the Trust PIERS on other than a pro rata basis, the Property
Trustee shall have received an Opinion of Counsel that the status of the Trust as a grantor trust for federal income tax purposes would not be adversely affected. The Property Trustee shall promptly notify the Securities Registrar in writing of the
Trust PIERS selected for redemption and, in the case of any Trust PIERS selected for partial redemption, the Liquidation Amount thereof to be redeemed. For all purposes of this Trust Agreement, unless the context otherwise requires, all provisions
relating to the redemption of Trust PIERS shall relate, in the case of any Trust PIERS redeemed or to be redeemed only in part, to the portion of the Liquidation Amount of Trust PIERS which has been or is to be redeemed. 
  
 (f) On or after June 15, 2009, the Depositor shall have the
right, upon not less than 30 nor more than 60 days notice, to redeem the Convertible Debentures, in whole or in part, for cash, and following such redemption, a Like Amount of Trust PIERS shall be redeemed by the Trust at the Redemption Price.

  
 (g) If, at any time, a Special Event shall
occur and be continuing, the Depositor shall have the right, upon not less than 30 nor more than 60 days’ notice, to redeem the Convertible Debentures, in whole but not in part, for cash within 90 days following the occurrence of such Special
Event, and, following such redemption, a Like Amount of Trust PIERS shall be redeemed by the Trust at the Redemption Price. 
  
 (h) Subject to the foregoing provisions of Section 4.02 and to applicable law (including, without limitation, United States federal
securities laws), the Company or its Affiliates may, at any time and from time to time, purchase outstanding Trust PIERS by tender, in the open market or by private agreement. 
  
 SECTION 4.03 Conversion. The Holders shall have the right at any time upon the occurrence of one or more of the
events set forth in the Trust PIERS Certificate and on the dates specified therein (each, a “Conversion Date”), at maturity or upon delivery of the notice of redemption (either at the option of the Depositor or pursuant to a Tax
Event or an Investment Company Event), at their option, to 

  

 19 

 
cause the Conversion Agent to convert Trust Securities, on behalf of the converting Holders, into cash, and if applicable, shares of the Common Stock in the
manner described herein on and subject to the following terms and conditions: 
  
 (a) The Trust Securities shall be convertible at the office of the Conversion Agent into cash and, if applicable, fully paid and nonassessable shares of Common Stock pursuant to the Holder’s written direction to
the Conversion Agent to exchange such Trust Securities for a portion of the Convertible Debentures theretofore held by the Trust on the basis of one Trust Securities per $50 principal amount of Convertible Debentures, and immediately convert such
amount of Convertible Debentures into cash, and if applicable, fully paid and nonassessable shares of Common Stock of the Depositor. The Convertible Debentures will be convertible at an initial conversion ratio of 1.2248 shares of Common Stock for
each $50 principal amount of Convertible Debentures in accordance with the provisions, and subject to certain adjustments, set forth in the Subordinated Indenture (as so adjusted from time to time, the “Conversion Ratio”). 

  
 (b) In order to exchange Trust Securities for
Convertible Debentures and convert such Convertible Debentures into cash and, if applicable, Common Stock, the Holder must submit to the Conversion Agent an irrevocable written notice of conversion in the form provided on the Trust PIERS Certificate
(or such other notice which is acceptable to the Depositor) (the “Conversion Request”), together, if the Trust Securities are in certificated form, with such Trust Security Certificates, duly endorsed or assigned to the Company or
in blank. The Conversion Request shall (i) set forth the Liquidation Amount of Trust Securities to be converted and the name or names, if other than the Holder, in which the cash should be delivered and, if applicable, shares of Common Stock should
be issued, and (ii) direct the Conversion Agent (A) to exchange such Trust Securities for a Like Amount of the Convertible Debentures held by the Trust, and (B) to immediately convert such Convertible Debentures on behalf of such Holder into cash
and, if applicable, Common Stock (at the Conversion Ratio specified in the preceding paragraph). The Conversion Agent shall notify the Trust of the Holder’s election to exchange Trust Securities for a portion of the Convertible Debentures held
by the Trust and the Property Trustee, on behalf of the Trust, shall, upon receipt of such notice, deliver to the Conversion Agent the appropriate principal amount of Convertible Debentures for exchange in accordance with this Section 4.03. The
Conversion Agent shall thereupon notify the Depositor of the Holder’s election to convert such Convertible Debentures into cash and, if applicable, shares of Common Stock. 
  
 (c) Any Trust PIERS or portion thereof surrendered for conversion during the period from the close of
business on the record date for any Distribution Date to the close of business on the Business Day next preceding the following Distribution Date shall (unless such Trust PIERS 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 Distribution Date) be accompanied by payment (the “Distribution
Reimbursement”), in New York Clearing House funds or other funds acceptable to the Depositor, of an amount equal to the Distributions (including Contingent Distributions, if any) otherwise payable on such Distribution Date on the
Liquidation Amount being converted. Notwithstanding the immediately preceding sentence, if (i) notice of redemption of Trust PIERS 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 Distribution Date to the close of business on the Business Day next preceding the following Distribution Date, and Trust PIERS or any portion thereof are surrendered for conversion after such record date but prior
to such Redemption Date, then the Holder surrendering such Trust PIERS or portion thereof shall not be required to pay the 

  

 20 

 
Distribution Reimbursement, and (ii) during an Extension Period a notice of redemption of Trust PIERS is mailed or otherwise given to Holders and Trust PIERS
or any portion thereof are surrendered for conversion after such notice but prior to the relevant Redemption Date, then the Holder surrendering such Trust PIERS or portion thereof shall not be required to pay the Distribution Reimbursement and shall
be entitled to receive payment of all accrued but unpaid Distributions (including Contingent Distributions, if any) on such Trust PIERS through the date of conversion on the Redemption Date. Except as otherwise set forth above in this paragraph, in
the case of any Trust PIERS which is converted, Distributions (including Contingent Distributions, if any) which are payable after the date of conversion of such Trust PIERS shall not be payable, and the Depositor shall not make nor be required to
make any other payment, adjustment or allowance with respect to accrued but unpaid Distributions (including Contingent Distributions, if any) on the Trust PIERS being converted, which shall be deemed to be paid in full. Except as provided herein, no
payment or other adjustment shall be made for Distributions (including Contingent Distributions, if any) accrued on any Trust PIERS converted or for dividends on any shares issued upon the conversion of such Trust PIERS. 
  
 (d) Each Holder of a Trust Security by his acceptance
thereof appoints the Bank (in such capacity the “Conversion Agent”) for the purpose of effecting the conversion of Trust Securities in accordance with this Section 4.03. In effecting the conversion and transactions described in this
Section 4.03, the Conversion Agent shall be acting as agent of the Holders directing it to effect such conversion transactions. The Conversion Agent is hereby authorized (i) to exchange Trust Securities from time to time for Convertible Debentures
held by the Trust in connection with the conversion of such Trust Securities with this Section 4.03, and (ii) to convert all or a portion of the Convertible Debentures into cash and, if applicable, shares of Common Stock and thereupon to deliver
such cash and, if applicable, shares of Common Stock in accordance with the provisions of this Section 4.03 and to deliver to the Trust a new Convertible Debenture or Convertible Debentures for any resulting unconverted principal amount. 

 
 (e) No fractional shares of Common Stock shall be issued
as a result of conversion, but in lieu thereof, such fractional interest shall be paid in cash (based on the Applicable Stock Price (as defined in the Subordinated Indenture) by the Depositor to the Trust, which in turn shall make such payment to
the Holder or Holders of Trust Securities so converted. 
  
 (f) The Depositor shall at all times reserve and keep available out of its authorized and unissued Common Stock, solely for issuance upon the conversion of the Convertible Debentures, free from any preemptive or other
similar rights, such number of shares of Common Stock as shall from time to time be issuable upon the conversion of all of the Convertible Debentures then outstanding. Notwithstanding the foregoing, the Depositor shall be entitled to deliver, upon
conversion of Convertible Debentures, shares of Common Stock reacquired and held in the treasury of the Depositor (in lieu of the issuance of authorized and unissued shares of Common Stock), so long as any such treasury shares are free and clear of
all liens, charges, security interests or encumbrances. Any shares of Common Stock issued upon conversion of the Convertible Debentures shall be duly authorized, validly issued, fully paid and nonassessable. The Trust shall deliver the shares of
Common Stock of the Depositor received upon conversion of the Convertible Debentures to the converting Holder free and clear of all liens, charges, security interests and encumbrances, except for United States withholding taxes. 
  
 (g) The Depositor shall pay any and all taxes that may be
payable in respect of the issue or delivery of shares of Common Stock, if applicable, on conversion of Convertible Debentures and the delivery of shares of Common Stock, if any, by the Trust upon conversion of the Trust Securities. The Depositor
shall not, however, be required to pay any tax that may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock, if applicable, in a name other than that in which the Trust Securities so converted were
registered, and no such issue or delivery shall be made unless and until the person requesting such issue has paid to the Trust the amount of any such tax or has established to the satisfaction of the Trust that such tax has been paid. 

 

 21 

 (h) Nothing in the preceding Section 4.03 shall limit the requirements of the Trust to
withhold taxes pursuant to the terms of the Trust Securities or as set forth in this Trust Agreement or otherwise require the Property Trustee or the Trust to pay any amount on account of such withholdings. 
  
 SECTION 4.04 Offer to Repurchase Upon Change of Control. 

 
 (a) If a Change of Control occurs, each Holder of Trust
PIERS will have the right to exchange all or any portion of such Holder’s Trust PIERS for Convertible Debentures having a principal amount equal to the Liquidation Amount of such Trust PIERS and to simultaneously require the Depositor to
repurchase such Convertible Debentures at the price and on the terms specified herein. 
  
 (b) If a Change of Control shall occur, the Depositor will offer (the “Change of Control Offer”) a Change of Control
payment in cash equal to 100% of the aggregate principal amount of Convertible Debentures repurchased plus accrued and unpaid interest (including any contingent or deferred interest) on the Convertible Debentures repurchased, to, but excluding, the
repurchase date. Within 30 days following any Change of Control, the Depositor will mail a notice to each Holder of Trust PIERS and the Property Trustee describing the transaction or transactions that constitute the Change of Control and offering to
repurchase Convertible Debentures for which Trust PIERS shall have been exchanged on the repurchase 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. To exercise a repurchase right arising under this Section 4.04, a Holder of the Trust PIERS must deliver, within such 30-day period specified in the Depositor’s notice, irrevocable
written notice to the Depositor, the Trust, the Property Trustee and the Exchange Agent of such Holder’s exercise of its repurchase right. The Depositor 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 Convertible 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 Depositor 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. 
  
 (c) On the Change of
Control payment date, the Depositor will, to the extent lawful: 
  
 (i) accept for payment all Convertible Debentures or portions of Convertible 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
Convertible Debentures or portions thereof properly tendered; and 
  
 (iii) deliver or cause to be delivered to the Trustee the Convertible Debentures or portions thereof properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Convertible
Debentures or portions of Convertible Debentures being purchased by the Depositor. 
  
 The Paying Agent will promptly mail to each validly-tendering Holder the Change of Control payment for such Trust PIERS converted to Convertible Debentures, and the Trustee will promptly authenticate and mail (or
cause to be transferred by book-entry) to each such Holder a new Convertible Debenture equal in principal amount to any unpurchased portion of the Convertible Debentures surrendered, if any; provided that each new Convertible Debenture will
be in a principal amount of $50 or an integral multiple of $50. 
  

 22 

 Any Trust PIERS as to which such right is exercised will be exchanged for Convertible Debentures by the
Property Trustee on behalf of the Depositor not less than three Business Days prior to the Change of Control payment date, which will not be later than 60 calendar days after the date of the Change of Control notice. 
  
 SECTION 4.05 Subordination of Common Securities. 
  
 (a) Payment of Distributions (including Contingent
Distributions, if any) on, and the Redemption Price of, the Trust Securities, as applicable, shall be made pro rata based on the Liquidation Amount of the Trust Securities; provided, however, that if on any Distribution Date or
Redemption Date an Event of Default shall have occurred and be continuing, no payment of any Distribution (including Contingent Distributions, if any) on, or Redemption Price of, any Common Security, and no other payment on account of the
redemption, liquidation or other acquisition of Common Securities, shall be made unless payment in full in cash of all accrued and unpaid Distributions, including Contingent Distributions, if any, on all Outstanding Trust PIERS for all Distribution
periods terminating on or prior thereto, or in the case of payment of the Redemption Price the full amount of such Redemption Price on all Outstanding Trust PIERS then called for redemption, shall have been made or provided for, and all funds
immediately available to the Property Trustee shall first be applied to the payment in full in cash of all Distributions (including Contingent Distributions, if any) on, or Redemption Price of, Trust PIERS then due and payable. 
  
 (b) In the case of the occurrence of any Event of Default,
the Holder of Common Securities will be deemed to have waived any such Event of Default under this Trust Agreement until the effect of all such Events of Default with respect to the Trust PIERS have been cured, waived or otherwise eliminated. Until
any such Events of Default under this Trust Agreement with respect to the Trust PIERS have been so cured, waived or otherwise eliminated, the Property Trustee shall act solely on behalf of the Holders of the Trust PIERS and not the Holder of the
Common Securities, and only the Holders of the Trust PIERS will have the right to direct the Property Trustee to act on their behalf. 
  
 SECTION 4.06 Payment Procedures. Payments in respect of the Trust PIERS shall be made by check mailed to the address of the Person entitled thereto
as such address shall appear on the Securities Register or, if the Trust PIERS are held by a Clearing Agency, such Distributions (including Contingent Distributions) shall be made to the Clearing Agency, which shall credit the relevant Persons’
accounts at such Clearing Agency on the applicable Distribution Dates. Payments in respect of the Common Securities shall be made in such manner as shall be mutually agreed between the Property Trustee and the Holder of the Common Securities.

  
 SECTION 4.07 Tax Returns and Reports. The
Administrative Trustee(s) shall prepare (or cause to be prepared), at the Depositor’s expense, and file all United States federal, state and local tax and information returns and reports required to be filed by or in respect of the Trust. The
Administrative Trustee(s) shall (a) prepare and file (or cause to be prepared and filed) the appropriate Internal Revenue Service form required to be filed in respect of the Trust in each taxable year of the Trust; and (b) prepare and furnish (or
cause to be prepared and furnished) to each Holder the appropriate Internal Revenue Service form required to be furnished to such Holder or the information required to be provided on such form. The Administrative Trustees shall provide the Depositor
with a copy of all such returns and reports promptly after such filing or furnishing. The Property Trustee shall comply with United States federal withholding and backup withholding tax laws and information reporting requirements with respect to any
payments to the Holders under the Trust Securities. 
  
 SECTION
4.08 [Reserved] 
  

 23 

 SECTION 4.09 Payments under the Indenture. Any amount payable hereunder to any Holder of Trust
PIERS shall be reduced by the amount of any corresponding payment such Holder has directly received under the Subordinated Indenture pursuant to Section 8.02(ii) of the Third Supplemental Indenture thereto and under Section 8.20 hereof. 

 
 SECTION 4.10 Exchange of Trust PIERS. 
  
 (a) If at any time the Company or any of its Affiliates is
the Holder of any Trust PIERS, the Company and such Affiliate(s) shall have the right to deliver to the Property Trustee all or such portion of their Trust PIERS as they elect and to receive, in exchange therefor, Convertible Debentures in an
aggregate principal amount equal to the aggregate stated Liquidation Amount of, with an interest rate identical to the distribution rate of, and accrued and unpaid interest equal to accumulated and unpaid Distributions on, such Trust PIERS. Such
election (i) shall be exercisable effective on any Distribution Date by the Company or its Affiliate(s) delivering to the Property Trustee a written notice of such election specifying the aggregate Liquidation Amount of the Trust PIERS with respect
to which such election is being made and the Distribution Date on which such exchange shall occur, which Distribution Date shall be not less than ten Business Days after the date of receipt by the Property Trustee of such election notice and (ii)
shall be conditioned upon the Company or its Affiliate(s) having delivered or caused to be delivered to the Property Trustee or its designee the Trust PIERS which are the subject of such election by 12:00 p.m. New York City time on the Distribution
Date on which such exchange is to occur. After the exchange, such Trust PIERS will be canceled and will no longer be deemed to be Outstanding and all rights of the Company or its Affiliate(s) with respect to such Trust PIERS will cease. 

 
 (b) In the case of an exchange described in (a) above,
the Trust will, on the date of such exchange, exchange Convertible Debentures having a principal amount equal to a proportional amount of the aggregate Liquidation Amount of the Outstanding Common Securities based on the ratio of the aggregate
Liquidation Amount of the Trust PIERS exchanged pursuant to (a) above divided by the aggregate Liquidation Amount of the Trust PIERS Outstanding immediately prior to such exchange, for such proportional amount of Common Securities held by the
Company (which contemporaneously shall be canceled and no longer be deemed to be Outstanding); provided, that the Company delivers or causes to be delivered to the Property Trustee or its designee the required amount of Common Securities to
be exchanged by 12:00 p.m. New York City time on the Distribution Date on which such exchange is to occur. 
  
 (c) The Property Trustee and any Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Trust
Securities to either calculate the Conversion Ratio or the amount of cash and, if applicable, shares of Common Stock deliverable in connection with a conversion of the Trust Securities or determine whether any facts exist which may require any
adjustment of 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 herein, or in any amendment provided to be employed, in making the same and shall be
protected in relying upon an Officers’ Certificate with respect to the same. Neither the Property Trustee nor any Conversion Agent shall be responsible for determining whether any event contemplated by this Trust Agreement has occurred which
makes the Trust Securities eligible for conversion until the Depositor has delivered to the Trustee and any Conversion Agent an Officers’ Certificate stating that such event has occurred, on which Certificate the Property Trustee and any such
Conversion Agent may conclusively rely, and the Depositor agrees to deliver such Officers’ Certificate to the Property Trustee and any such Conversion Agent immediately after the occurrence of any such event.

 ARTICLE V 
  

TRUST SECURITIES CERTIFICATES 
  
 SECTION 5.01 Initial Ownership. Upon the creation of the Trust by the contribution by the Depositor pursuant to Section 2.03 and until the issuance
of the Trust Securities, and at any time during which no Trust Securities are Outstanding, the Depositor shall be the sole beneficial owner of the Trust. 
  
 SECTION 5.02 The Trust Securities Certificates. Each of the Trust PIERS Certificate and Common Securities Certificates shall be issued in minimum
denominations of the Liquidation Amount and integral multiples of such Liquidation Amount in excess thereof. The Trust Securities Certificates shall be executed on behalf of the Trust by manual or facsimile signature of at least one Administrative
Trustee. Trust Securities Certificates bearing the manual or facsimile signatures of individuals who were, at the time when such signatures shall have been affixed, authorized to sign on behalf of the Trust, shall be validly issued and entitled to
the benefits of this Trust Agreement, notwithstanding that such individuals or any of them shall have ceased to be so authorized prior to the delivery of such Trust Securities Certificates or did not hold such offices at the date of delivery of such
Trust Securities Certificates. A transferee of a Trust Securities Certificate shall become a Holder, and shall be entitled to the rights and subject to the obligations of a Holder hereunder, upon due registration of such Trust Securities Certificate
in such transferee’s name pursuant to Section 5.04. 
  
 SECTION 5.03 Execution, Authentication and Delivery of Trust Securities Certificates. (a) On the Issue Date, the Administrative Trustees shall cause Trust Securities Certificates, in an aggregate Liquidation Amount as provided in
Sections 2.04 and 2.05, to be executed on behalf of the Trust by at least one of the Administrative Trustees and delivered to or upon the written order of the Depositor signed by its Chairman of the Board, its President or any Vice President,
without further corporate action by the Depositor, in authorized denominations. 
  
 (b) A Trust PIERS Certificate shall not be valid until authenticated by the manual signature of an authorized signatory of the Property
Trustee in substantially the form set forth in Exhibit C hereto. The signature shall be conclusive evidence that the Trust PIERS Certificate has been authenticated under this Trust Agreement. Each Trust PIERS Certificate shall be dated the date of
its authentication. 
  
 (c) Upon the written
order of the Trust signed by one of the Administrative Trustees, the Property Trustee shall authenticate and make available for delivery the Trust PIERS Certificates. 
  
 (d) The Property Trustee may appoint an authenticating agent acceptable to the Trust to authenticate the
Trust PIERS. An authenticating agent may authenticate Trust PIERS whenever the Property Trustee may do so. Each reference in this Trust Agreement to authentication by the Property Trustee includes authentication by such agent. An authentication
agent has the same rights as the Property Trustee to deal with the Depositor or an Affiliate. 
  
 SECTION 5.04 Registration of Transfer and Exchange of Trust PIERS Certificates. A registrar (the “Securities Registrar”) shall keep or cause to be kept, at the office or agency maintained
pursuant to Section 5.09, a register (the “Securities Register”) in which, subject to such reasonable regulations as it may prescribe, the Securities Registrar shall provide for the registration of Trust PIERS Certificates and the
Common Securities Certificates (subject to Section 5.12 in the case of the Common Securities Certificates) and registration of transfers and exchanges of Trust PIERS Certificates as herein provided. The Property Trustee shall be the initial
Securities Registrar. 
  

 25 

 Upon surrender for registration of transfer of any Trust PIERS Certificate at the office or agency
maintained pursuant to Section 5.09, an Administrative Trustee shall execute on behalf of the Trust by manual or facsimile signature and the Property Trustee shall authenticate and deliver in the name of the designated transferee or transferees one
or more new Trust PIERS Certificates in authorized denominations of a like aggregate Liquidation Amount dated the date of execution by such Administrative Trustee or Trustees. The Securities Registrar shall not be required to register the transfer
of any Trust PIERS that have been called for redemption. At the option of a Holder, Trust PIERS Certificates may be exchanged for other Trust PIERS Certificates in authorized denominations of the same class and of a like aggregate Liquidation Amount
upon surrender of the Trust PIERS Certificates to be exchanged at the office or agency maintained pursuant to Section 5.09. 
  
 Every Trust PIERS Certificate presented or surrendered for registration of transfer or exchange shall be accompanied by a written instrument of transfer
in form satisfactory to the Administrative Trustees and the Securities Registrar duly executed by the Holder or his attorney duly authorized in writing. Each Trust PIERS Certificate surrendered for registration of transfer or exchange shall be
canceled and subsequently disposed of by the Securities Registrar in accordance with its customary practice. 
  
 No service charge shall be made for any registration of transfer or exchange of Trust PIERS Certificates, but the Securities Registrar may require payment
of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Trust PIERS Certificates. 
  
 SECTION 5.05 Book-Entry PIERS Certificate. 
  
 (a) Any Book-Entry Trust PIERS Certificate issued under this Trust Agreement shall be registered in the name of the nominee of the
Clearing Agency and delivered to such custodian therefor, and such Book-Entry Trust PIERS Certificate shall constitute a single Trust PIERS for all purposes of this Trust Agreement. 
  
 (b) Notwithstanding any other provision in this Trust Agreement, no Book-Entry Trust PIERS Certificate may
be exchanged for Definitive Trust PIERS Certificates registered in the names of persons other than the Clearing Agency or its nominee unless (i) the Clearing Agency notifies the Administrative Trustees that it is unwilling or unable to continue as a
depositary for such Book-Entry Trust PIERS Certificate and the Administrative Trustees fail to appoint a qualified successor depositary, (ii) the Clearing Agency has ceased to be a clearing agency registered under the Exchange Act or (iii) there
shall have occurred and be continuing an Event of Default. 
  
 (c) If a Definitive Trust PIERS Certificate is to be exchanged in whole or in part for a beneficial interest in a Book-Entry Trust PIERS Certificate, then either (i) such Book-Entry Trust PIERS Certificate shall be so
surrendered for exchange or cancellation as provided in this Article V or (ii) the Liquidation Amount thereof shall be reduced or increased by an amount equal to the portion thereof to be so exchanged or canceled, or equal to the Liquidation Amount
of such other Trust PIERS to be so exchanged for a beneficial interest therein, as the case may be, by means of an appropriate adjustment made on the records of the Securities Registrar, whereupon the Property Trustee, in accordance with the rules
and procedures of the depositary for such Book-Entry Trust PIERS Certificate (the “Applicable Procedures”), shall instruct the Clearing Agency or its authorized representative to make a corresponding adjustment to its records. Upon
any such surrender or adjustment of a Book-Entry Trust PIERS Certificate by the Clearing Agency, accompanied by registration instructions, the Administrative Trustees shall execute and the Property Trustee shall deliver any Trust PIERS issuable in
exchange for such Book-Entry Trust PIERS Certificate (or any portion thereof) in accordance with the instructions of 

  

 26 

 
the Clearing Agency. The Property Trustee shall not be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be fully
protected in relying on, such instructions. 
  
 (d) Every Definitive Trust PIERS Certificate executed and delivered upon registration of transfer of, or in exchange for or in lieu of, a Book-Entry Trust PIERS Certificate or any portion thereof, whether pursuant to this Article V or
otherwise, shall be executed and delivered in the form of, and shall be, a Book-Entry Trust PIERS Certificate, unless such Book-Entry Trust PIERS Certificate is registered in the name of a Person other than the Clearing Agency for such Book-Entry
Trust PIERS Certificate or a nominee thereof. 
  
 (e) The Clearing Agency or its nominee, as the registered owner of a Book-Entry Trust PIERS Certificate, shall be considered the Holder of the Trust PIERS represented by such Book-Entry Trust PIERS Certificate for all purposes under this
Trust Agreement and the Trust PIERS, the owners of beneficial interests in such Book-Entry Trust PIERS Certificate shall hold such interests pursuant to the Applicable Procedures and, except as otherwise provided herein, shall not be entitled to
receive physical delivery of any such Trust PIERS in definitive form and shall not be considered the Holders thereof under this Trust Agreement. Accordingly, any such owner’s beneficial interest in the Book-Entry Trust PIERS Certificate shall
be shown only on, and the transfer of such interest shall be effected only through, records maintained by the Clearing Agency or its nominee. Neither the Property Trustee, the Securities Registrar nor the Depositor shall have any liability in
respect of any transfers effected by the Clearing Agency. 
  
 (f) The rights of owners of beneficial interests in a Book-Entry Trust PIERS Certificate shall be exercised only through the Clearing Agency and shall be limited to those established by law and agreements between such
owners and the Clearing Agency. 
  
 SECTION 5.06 Mutilated,
Destroyed, Lost or Stolen Trust Securities Certificates. If (a) any mutilated Trust Securities Certificate shall be surrendered to the Securities Registrar, or if the Securities Registrar shall receive evidence to its satisfaction of the
destruction, loss or theft of any Trust Securities Certificate and (b) there shall be delivered to the Securities Registrar and the Administrative Trustees such security or indemnity as may be required by them to hold each of them harmless, then in
the absence of notice that such Trust Securities Certificate shall have been acquired by a protected purchaser, the Administrative Trustees or any one of them on behalf of the Trust shall execute and make available for delivery, in exchange for or
in lieu of any such mutilated, destroyed, lost or stolen Trust Securities Certificate, a new Trust Securities Certificate of like class, tenor and denomination. In connection with the issuance of any new Trust Securities Certificate under this
Section, the Administrative Trustees or the Securities Registrar may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith. Any duplicate Trust Securities Certificate issued
pursuant to this Section shall constitute conclusive evidence of an ownership interest in the Trust, as if originally issued, whether or not the lost, stolen or destroyed Trust Securities Certificate shall be found at any time. 
  
 SECTION 5.07 Persons Deemed Holders. Prior to due presentation of a
Trust Securities Certificate for registration of transfer, the Trustees or the Securities Registrar shall treat the Person in whose name any Trust Securities Certificate shall be registered in the Securities Register as the owner of such Trust
Securities Certificate for the purpose of receiving Distributions, including Contingent Distributions, if any (subject to Section 4.01(d)), and for all other purposes whatsoever, and neither the Trustees nor the Securities Registrar shall be bound
by any notice to the contrary. 
  
 SECTION 5.08 Access to List
of Holders’ Names and Addresses. The Administrative Trustees or the Depositor shall furnish or cause to be furnished (unless the Property Trustee or the 

  

 27 

 
Depositor is acting as Securities Registrar with respect to the Trust Securities) to (i) the Property Trustee semi-annually, not later than May 1 and
November 1 in each year, and (ii) the Property Trustee within 15 days after receipt by any Administrative Trustee of a request therefor from the Property Trustee in writing, a list, in such form as the Property Trustee may reasonably require, of the
names and addresses of the Holders as of a date not more than 15 days prior to the time such list is furnished in each case to the extent such information is the possession or control of the Administrative trustees or the Depositor and is not
identical to a previously supplied list or has not otherwise been received by the Property Trustee in its capacity as Securities Registrar. The rights of Holders to communicate with other Holders with respect to their rights under this Trust
Agreement or under the Trust Securities, and the corresponding rights of the Trustee shall be as provided in the Trust Indenture Act. Each Holder, by receiving and holding a Trust Securities Certificate, shall be deemed to have agreed not to hold
either the Depositor, the Administrative Trustees or the Property Trustee accountable by reason of the disclosure of its name and address, regardless of the source from which such information was derived. 
  
 SECTION 5.09 Maintenance of Office or Agency. The Administrative
Trustees shall maintain in the Borough of Manhattan, New York, an office or offices or agency or agencies where Trust PIERS Certificates may be surrendered for registration of transfer or exchange and where notices and demands to or upon the
Trustees in respect of the Trust Securities Certificates may be served. The Administrative Trustees initially designate the Corporate Trust Office of the Property Trustee, 4 New York Plaza, 15th Floor, New York, New York 10004, as its principal
agency for such purposes. The Administrative Trustees shall give prompt written notice to the Depositor and to the Holders of any change in the location of the Securities Register or any such office or agency. 
  
 SECTION 5.10 Appointment of Paying Agent. The Paying Agent shall make
Distributions, Contingent Distributions and other payments provided hereby to Holders from the Payment Account and shall report the amounts of such Distributions, Contingent Distributions and payments to the Property Trustee and the Administrative
Trustees. Any Paying Agent shall have the revocable power to withdraw funds from the Payment Account for the purpose of making the Distributions, Contingent Distributions and payments provided hereby. The Administrative Trustees may revoke such
power and remove the Paying Agent if such Trustees determine in their sole discretion that the Paying Agent shall have failed to perform its obligations under this Agreement in any material respect. The Paying Agent shall initially be the Property
Trustee, and it may choose any co-paying agent that is acceptable to the Administrative Trustees and the Depositor. Any Person acting as Paying Agent shall be permitted to resign as Paying Agent upon 30 days written notice to the Administrative
Trustees and the Depositor. In the event that a Paying Agent shall resign or be removed, the Administrative Trustees shall appoint a successor that is acceptable to the Depositor to act as Paying Agent (which shall be a bank or trust company). The
Administrative Trustees shall cause such successor Paying Agent or any additional Paying Agent appointed by the Administrative Trustees to execute and deliver to the Trustees an instrument in which such successor Paying Agent or additional Paying
Agent shall agree with the Trustees that as Paying Agent, such successor Paying Agent or additional Paying Agent will hold all sums, if any, held by it for payment to the Holders in trust for the benefit of the Holders entitled thereto until such
sums shall be paid to such Holders. The Paying Agent shall return all unclaimed funds to the Property Trustee and upon removal of a Paying Agent such Paying Agent shall also return all funds in its possession to the Property Trustee. The provisions
of Sections 8.01, 8.03 and 8.06 shall apply to the Property Trustee also in its role as Paying Agent, for so long as the Property Trustee shall act as Paying Agent and, to the extent applicable, to any other paying agent appointed hereunder. Any
reference in this Agreement to the Paying Agent shall include any co-paying agent unless the context requires otherwise. 
  
 SECTION 5.11 Appointment of Conversion Agent. The Conversion Agent shall convert the Trust Securities of the Holders in accordance with Section
4.03 hereof. The Administrative Trustees may revoke such power and remove the Conversion Agent if such Trustees determine in their sole discretion 

  

 28 

 
that the Conversion Agent shall have failed to perform its obligations under this Trust Agreement in any material respect. The Conversion Agent shall
initially be the Bank, and any co-paying agent chosen by the Bank, and acceptable to the Administrative Trustees and the Depositor. Any Person acting as Conversion Agent shall be permitted to resign as Conversion Agent upon 30 days written notice to
the Administrative Trustees and the Depositor. In the event that the Bank shall no longer be the Conversion Agent or a successor Conversion Agent shall resign or its authority to act shall be revoked, the Administrative Trustees shall appoint a
successor that is acceptable to the Depositor to act as Conversion Agent (which shall be a bank or a trust company). The provisions of Sections 8.01, 8.03 and 8.06 of this Trust Agreement shall apply to the Bank also in its role as Conversion Agent,
for so long as the Bank shall act as Conversion Agent and, to the extent applicable, to any other conversion agent appointed hereunder, and any Conversion Agent shall be bound by the requirements with respect to conversion agents of securities
issued pursuant to the Trust Indenture Act. Any reference in this Trust Agreement to the Conversion Agent shall include any co-paying agent unless the context requires otherwise. 
  
 SECTION 5.12 Ownership of Common Securities by Depositor. On the Issue Date, the Depositor shall receive, and
thereafter retain, beneficial and record ownership of the Common Securities. Any attempted transfer of the Common Securities, except for transfers by operation of law or to an Affiliate of the Depositor or a permitted successor pursuant to Section
5.01 of the Subordinated Indenture, shall be void. The Administrative Trustees shall cause each Common Securities Certificate issued to the Depositor to contain a legend stating “THIS CERTIFICATE IS NOT TRANSFERABLE EXCEPT AS PROVIDED IN THE
TRUST AGREEMENT REFERRED TO HEREIN”. 
  
 SECTION 5.13
Book-Entry Trust PIERS Certificates; Common Securities Certificate. 
  
 (a) The Trust PIERS Certificates, upon original issuance, will be issued in the form of a typewritten Trust PIERS Certificate or Book-Entry Trust PIERS Certificates, to be delivered to DTC, the initial Clearing
Agency, by, or on behalf of, the Trust. Such Trust PIERS Certificate or Certificates shall initially be registered on the Securities Register in the name of Cede & Co., the nominee of the initial Clearing Agency, and no Owner will receive a
Definitive Trust PIERS Certificate representing such beneficial owner’s interest in such Trust PIERS, except as provided in Section 5.15. Unless and until Definitive Trust PIERS Certificates have been issued to Owners pursuant to Section 5.15:

  
 (A) the provisions of this Section 5.13(a)
shall be in full force and effect; 
  
 (B) the
Securities Registrar and the Trustees shall be entitled to deal with the Clearing Agency for all purposes of this Trust Agreement relating to the Book-Entry Trust PIERS Certificates (including the payment of principal of and interest on the
Book-Entry Trust PIERS and the giving of instructions or directions to Owners of Book-Entry Trust PIERS) as the sole Holder of Book-Entry Trust PIERS and shall have no obligations to the Owners thereof; 
  
 (C) to the extent that the provisions of this Section
conflict with any other provisions of this Trust Agreement, the provisions of this Section shall control; and 
  
 (D) the rights of the Owners of the Book-Entry Trust PIERS Certificates shall be exercised only through the Clearing Agency and shall be
limited to those established by law and agreements between such Owners and the Clearing Agency and/or the Clearing Agency Participants. Pursuant to the Certificate Depository Agreement, unless and until Definitive Trust PIERS Certificates are issued
pursuant to Section 5.15, the Clearing Agency will make book-entry transfers among the Clearing Agency 

  

 29 

 
Participants and receive and transmit payments on the Trust PIERS to such Clearing Agency Participants. 
  
 (b) A single Common Securities Certificate representing the
Common Securities shall be issued to the Depositor in the form of a definitive Common Securities Certificate. 
  
 SECTION 5.14 Notices to Clearing Agency. To the extent a notice or other communication to the Owners is required under this Trust Agreement, unless
and until Definitive Trust PIERS Certificates shall have been issued to Owners pursuant to Section 5.15, the Trustees shall give all such notices and communications specified herein to be given to Owners to the Clearing Agency, and shall have no
obligations to the Owners. 
  
 SECTION 5.15 Definitive Trust
PIERS Certificates. If (i) the Clearing Agency notifies the Administrative Trustees that it is unwilling or unable to continue as a depositary with respect to the Trust PIERS Certificates and the Administrative Trustees fail to appoint a
qualified successor depositary, (ii) the Clearing Agency has ceased to be a clearing agency registered under the Exchange Act or (iii) there shall have occurred and be continuing an Event of Default, then the Administrative Trustees shall notify the
Clearing Agency and Holders of the Trust PIERS. Upon surrender to the Administrative Trustees of the typewritten Trust PIERS Certificate or Certificates representing the Book-Entry Trust PIERS Certificates by the Clearing Agency, accompanied by
registration instructions, the Administrative Trustees or any one of them shall execute the Definitive Trust PIERS Certificates in accordance with the instructions of the Clearing Agency. Neither the Securities Registrar nor the Trustees shall be
liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of Definitive Trust PIERS Certificates, the Trustees shall recognize the Holders of the
Definitive Trust PIERS Certificates as Holders. The Definitive Trust PIERS Certificates shall be printed, lithographed or engraved or may be produced in any other manner as is reasonably acceptable to the Administrative Trustees, as evidenced by the
execution thereof by the Administrative Trustees or any one of them. 
  
 SECTION 5.16 Rights of Holders. The legal title to the Trust Property is vested exclusively in the Property Trustee (in its capacity as such) in accordance with Section 2.09, and the Holders shall not have any right or title therein
other than the beneficial ownership interest in the assets of the Trust conferred by their Trust Securities, and they shall have no right to call for any partition or division of property, profits or rights of the Trust except as described below.
The Trust Securities shall be personal property giving only the rights specifically set forth therein and in this Trust Agreement. The Trust Securities shall have no preemptive or other similar rights and when issued and delivered to Holders against
payment of the purchase price therefor, except as otherwise provided in the Expense Agreement and Section 10.01 hereof, will be fully paid and nonassessable by the Trust. Except as otherwise provided in the Expense Agreement and Section 10.01
hereof, the Holders of the Trust Securities shall be entitled to the same limitation of personal liability extended to stockholders of private corporations for profit organized under the General Corporation Law of the State of Delaware.

 ACTS OF HOLDERS OF TRUST PIERS; VOTING 
  
 SECTION 6.01 Limitations on Voting Rights. 
  
 (a) Except as provided in this Trust Agreement, in the
Subordinated Indenture, and as otherwise required by law, no Holder of Trust PIERS shall have any right to vote or in any manner otherwise control the administration, operation and management of the Trust or the obligations of the 

  

 30 

 
parties hereto, nor shall anything herein set forth, or contained in the terms of the Trust Securities Certificates, be construed so as to constitute the
Holders from time to time as partners or members of an association. 
  
 (b) So long as any Convertible Debentures are held by the Property Trustee, the Holders of a majority in Liquidation Amount of the Trust PIERS will have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Property Trustee, or executing any trust or power conferred on the Property Trustee with respect to such Convertible Debentures, including the right to direct the Property Trustee to (i) waive any past
default which is waivable under the Subordinated Indenture, (ii) exercise the remedies available to it under the Subordinated Indenture as a Holder of the Convertible Debentures or (iii) consent to any amendment, modification or termination of the
Subordinated Indenture or the Convertible Debentures, where such consent shall be required, or to any other action, as holder of the Convertible Debentures, under the Subordinated Indenture; provided, however, that if an Event of
Default has occurred and is continuing, then Holders of at least 25% of the aggregate liquidation amount of the Trust PIERS may direct the Property Trustee to declare the principal of and premium, if any, and interest (including contingent interest)
on the Convertible Debentures due and payable; and further provided, that where a consent or action under the Subordinated Indenture would require the consent or act of Holders of more than a majority of the aggregate principal amount
of Convertible Debentures affected thereby, only Holders of the percentage of the aggregate stated Liquidation Amount of the Trust PIERS which is at least equal to the percentage required under the Convertible Debentures Indenture may direct the
Property Trustee to give such consent or take such action. The Trustees shall not revoke any action previously authorized or approved by a vote of the Holders of Trust PIERS, except pursuant to a subsequent vote of the Holders of Trust PIERS. The
Property Trustee shall notify all Holders of the Trust PIERS of any notice of an Event of Default received from the Indenture Trustee or the Company with respect to the Convertible Debentures. In addition to obtaining the foregoing approvals of the
Holders of the Trust PIERS, prior to taking any of the foregoing actions, the Trustees shall, at the expense of the Depositor, obtain an independent Opinion of Counsel to the effect that the Trust will not be classified as other than a grantor trust
for United States federal income tax purposes on account of such action and each Holder of the Trust PIERS will be treated as owning an undivided beneficial ownership interest in the Convertible Debentures. 
  
 (c) If any proposed amendment to this Trust Agreement
provides for, or the Trustees otherwise propose to effect, (i) any action that would adversely affect in any material respect the powers, preferences or special rights of the Trust PIERS, whether by way of amendment to this Trust Agreement or
otherwise, or (ii) the dissolution, winding-up or termination of the Trust, other than pursuant to the terms of this Trust Agreement, then the Holders of Outstanding Trust PIERS as a class will be entitled to vote on such amendment or proposal and
such amendment or proposal shall not be effective except with the approval of the Holders of at least a majority in Liquidation Amount of the Outstanding Trust PIERS. In addition to obtaining the foregoing approvals of the Holders of the Trust
PIERS, prior to taking any of the foregoing actions, the Trustees shall, at the expense of the Depositor, obtain an independent Opinion of Counsel to the effect that the Trust will not be classified as other than a grantor trust for United States
federal income tax purposes on account of such action and each Holder of the Trust PIERS will be treated as owning an undivided beneficial ownership interest in the Convertible Debentures. 
  
 (d) A Holder may institute a legal proceeding directly
against the Depositor under the Guarantee to enforce its rights under the Guarantee without first instituting a legal proceeding against the Guarantee Trustee (as defined in the Guarantee Agreement), the Trust or any Person. 
  

 31 

 SECTION 6.02 Voting Rights. Holders shall be entitled to one vote for each $50 of Liquidation
Amount represented by their Trust Securities in respect of any matter as to which such Holders are entitled to vote. 
  
 SECTION 6.03 Holder Action by Written Consent. Any action which may be taken by Holders at a meeting may be taken without a meeting if Holders
holding a majority of all outstanding Trust Securities entitled to vote in respect of such action (or such other proportion thereof as shall be required by any express provision of this Trust Agreement) shall consent to the action in writing (based
upon their Liquidation Amount). 
  
 SECTION 6.04 Record Date
for Voting and Other Purposes. For the purposes of determining the Holders who are entitled to notice of and to vote at any meeting or by written consent, or for the purpose of any other action, the Administrative Trustees may from time to time
fix a date, not more than 90 days prior to the date of any meeting of Holders or other action, as the case may be, as a record date for the determination of the identity of the Holders of record for such purposes. 
  
 SECTION 6.05 Acts of Holders. 
  
 (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Trust Agreement to be given, made or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an
agent appointed in writing; and, except as otherwise expressly provided herein, such action shall become effective when such instrument or instruments are delivered to the Administrative Trustees. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Trust Agreement and (subject to Section 8.01) conclusive in favor of the Trustees, if made in the manner provided in this Section. 
  
 (b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the
affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution
thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustees deem sufficient. 
  
 (c) The ownership of Trust PIERS shall be proved by the Securities Register. 
  
 (d) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Trust Security shall bind every future Holder of the same Trust Security and the Holder of every Trust Security issued upon the registration of transfer thereof or in exchange therefor or in lieu
thereof in respect of anything done, omitted or suffered to be done by the Trustees or the Trust in reliance thereon, whether or not notation of such action is made upon such Trust Security. 
  
 (e) Without limiting the foregoing, a Holder entitled
hereunder to take any action hereunder with regard to any particular Trust Security may do so with regard to all or any part of the Liquidation Amount of such Trust Security or by one or more duly appointed agents each of which may do so pursuant to
such appointment with regard to all or any part of such Liquidation Amount. 
  

 32 

 (f) If any dispute shall arise between the Holders of Trust Securities and the
Administrative Trustees or among such Holders or Trustees with respect to the authenticity, validity or binding nature of any request, demand, authorization, direction, consent, waiver or other Act of such Holder or Trustee under this Article VI,
then the determination of such matter by the Property Trustee shall be conclusive with respect to such matter. 
  
 SECTION 6.06 Inspection of Records. Upon reasonable notice to the Trustees, the records of the Trust shall be open to inspection by Holders during
normal business hours for any purpose reasonably related to such Holder’s interest as a Holder.

 ARTICLE VIII 
  
 THE TRUSTEES 
  
 SECTION 8.01 Certain Duties and Responsibilities. 
  
 (a) The rights, duties and responsibilities of the Trustees
shall be as provided by this Trust Agreement and, in the case of the Property Trustee, by the Trust Indenture Act. For purposes of Sections 315(a) and 315(c) of the Trust Indenture Act, the term “default” is hereby defined to mean an Event
of Default has occurred and is continuing. Notwithstanding the foregoing, no provision of this Trust Agreement shall require the Trustees to expend or risk their own funds or otherwise incur any financial liability in the performance of any of their
duties hereunder, or in the exercise of any of their rights or powers, if they shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to them. The
Delaware Trustee and the Administrative Trustees shall have no liability under this Trust Agreement except for gross negligence or willful misconduct. The Property Trustees shall have no liability under this Trust Agreement except for negligence and
willful misconduct. Whether or not therein expressly so provided, every provision of this Trust Agreement relating to the conduct or affecting the liability of or affording protection to the Trustees shall be subject to the provisions of this
Section 8.01. To the extent that, at law or in equity, the Delaware Trustee or an Administrative Trustee has duties (including fiduciary duties) and liabilities relating thereto to the Trust or to the Holders, the Delaware Trustee or such
Administrative Trustee shall not be liable to the Trust or to any Holder for such Trustee’s good faith reliance on the provisions of this Trust Agreement. The provisions of this Trust Agreement, to the extent that they restrict the duties and
liabilities of the Delaware Trustee or the Administrative Trustees otherwise existing at law or in equity, are agreed by the Depositor and the Holders to replace such other duties and liabilities of the Delaware Trustee or the Administrative
Trustees, as the case may be. 
  
 (b) All
payments made by the Property Trustee in respect of the Trust Securities shall be made only from the income and proceeds from the Trust Property and only to the extent that there shall be sufficient income or proceeds from the Trust Property to
enable the Property Trustee to make payments in accordance with the terms hereof. Each Holder, by its acceptance of a Trust Security, agrees that it will look solely to the income and proceeds from the Trust Property to the extent available for
distribution to it as herein provided and that the Trustees are not personally liable to it for any amount distributable in respect of any Trust Security or for any other liability in respect of any Trust Security. This Section 8.01(b) does not
limit the liability of the Trustees expressly set forth elsewhere in this Trust Agreement or, in the case of the Property Trustee, in the Trust Indenture Act. 
  

(c) No provision of this Trust Agreement shall be construed to relieve the Property Trustee from liability for its own negligent
action, its own negligent failure to act, or its own willful misconduct, except that: 
  
 (i) the Property Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer of the Property
Trustee, unless it shall be proved that the Property Trustee was negligent in ascertaining the pertinent facts; 
  

 35 

 (ii) the Property Trustee shall not be liable with respect to any action taken or omitted
to be taken by it in good faith in accordance with the direction of the Holders of not less than a majority in Liquidation Amount of the Trust Securities relating to the time, method and place of conducting any proceeding for any remedy available to
the Property Trustee, or exercising any trust or power conferred upon the Property Trustee under this Trust Agreement; 
  
 (iii) the Property Trustee’s sole duty with respect to the custody, safe keeping and physical preservation of the Convertible

Trustee under this Trust Agreement and the Trust Indenture Act; 
  
 (iv) the Property Trustee shall not be liable for any interest on any money received by it except as it may otherwise agree with the Depositor and money held by the Property Trustee need not be segregated from other

 (v) the Property Trustee shall not be responsible for monitoring the compliance by the Administrative
Trustees or the Depositor with their respective duties under this Trust Agreement, nor shall the Property Trustee be liable for the negligence, default or misconduct of the Administrative Trustees or the Depositor; and 
  
 (vi) no provision of this Trust Agreement shall require the
Property Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. 
  
 (d) Notwithstanding anything contained in this Trust Agreement to the contrary, the duties and responsibilities of the Property Trustee
under this Trust Agreement shall be subject to the protections, exculpations and limitations on liability afforded to an indenture trustee under the provisions of the Trust Indenture Act. For the purposes of Sections 315(b) and 315(d)(2) of the

her knowledge of and familiarity with the particular subject. 
  
 (e) Whether or not therein expressly so provided, every provision of this Trust Agreement relating to the conduct or affecting the liability of or affording protection to the Property Trustee shall be subject to the
provisions of this Section.

after the occurrence of the any Event of Default actually known to the Property Trustee or, to the extent Section 3.15(b) of the Trust Indenture Act applies, 90 days after the occurrence of any default hereunder known to the Property Trustee, the
Property Trustee 

  

 36 

 
shall transmit, in the manner and to the extent provided in 313(c) of the Trust Indenture Act, notice of such Event of Default or default to the Holders, the
Administrative Trustees and the Depositor, unless such Event of Default shall have been cured or waived. For the purpose of this Section 8.02, the term “default” means any event which is, or after notice or lapse of time or both would
become, an Event of Default. 
  
 (b) Within five
Business Days after the receipt of notice of the Depositor’s exercise of its right to defer the payment of interest on the Debentures pursuant to the Indenture, the Property Trustee shall transmit, in the manner and to the extent provided in

 SECTION 8.03 Certain Rights of Property Trustee. Subject to the provisions of Section 8.01 and except as provided by law: 
  
 (i) the Property Trustee may rely and shall be protected in
acting or refraining from acting in good faith upon any resolution, Opinion of Counsel, certificate, written representation of a Holder or transferee, certificate of auditors or any other certificate, statement, instrument, opinion, report, notice,
request, consent, order, appraisal, bond or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; 
  
 (ii) if (A) in performing its duties under this Trust Agreement the Property Trustee is required to decide
between alternative courses of action, or (B) in construing any of the provisions in this Trust Agreement the Property Trustee finds the same ambiguous or inconsistent with any other provisions contained herein, or (C) the Property Trustee is unsure
of the application of any provision of this Trust Agreement, then, except as to any matter as to which the Holders of the Trust PIERS are entitled to vote under the terms of this Trust Agreement, the Property Trustee shall deliver a notice to the
Depositor requesting written instructions of the Depositor as to the course of action to be taken. The Property Trustee shall take such action, or refrain from taking such action, as the Property Trustee shall be instructed in writing to take, or to
refrain from taking, by the Depositor; provided, however, that if the Property Trustee does not receive such instructions of the Depositor within ten Business Days after it has delivered such notice, or such reasonably shorter period
of time set forth in such notice (which to the extent practicable shall not be less than two Business Days), it may, but shall be under no duty to, take or refrain from taking such action not inconsistent with this Trust Agreement as it shall deem
advisable and in the best interests of the Holders, in which event the Property Trustee shall have no liability except for its own negligence or willful misconduct; 
  
 (iii) the Property Trustee may consult with counsel of its selection and the written advice of such counsel
or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; 
  
 (iv) subject to Section 6.01(b), the Property Trustee shall
be under no obligation to exercise any of the rights or powers vested in it by this Trust Agreement at the request or direction of any of the Holders pursuant to this Trust Agreement, unless such Holders shall have offered to the Property Trustee
security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction; nothing contained herein shall, however, relieve the Property Trustee of the
obligation, upon the occurrence of any Event of Default (that has not been cured or waived) to exercise such of the rights and powers vested in it by this Trust Agreement, and to use the same degree of care and 

  

 37 

 
skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs; 
  
 (v) the Property Trustee shall not be bound to make any
investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond or other document, unless requested in writing to do so by one or more Holders;

  
 (vi) the Property Trustee may execute any of
the trusts or powers hereunder or perform any duties hereunder either directly or by or through its agents or attorneys, provided that the Property Trustee shall be responsible for its own negligence or recklessness with respect to selection
of any agent or attorney appointed by it hereunder; 
  
 (vii) any request or direction or act of the Depositor mentioned herein or contemplated by this Trust Agreement shall be sufficiently evidenced by an Officers’ Certificate and any resolution of the Board of Directors may be
sufficiently evidenced by a Board Resolution; 
  
 (viii) whenever in the administration of this Trust Agreement the Property Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Property Trustee (unless
other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, conclusively rely upon an Officers’ Certificate; 
  
 (ix) the Property Trustee shall not be liable for any action taken, suffered, or omitted to be taken by it in good faith and reasonably
believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Trust Agreement;

thereof; 
  
 (xi) the rights, privileges,
protections, immunities and benefits given to the Property Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Property Trustee in each of its capacities hereunder, and each agent,
custodian and other Person employed to act hereunder; and 
  
 (xii) the Property Trustee shall have no duty to see to any recording, filing or registration of any instrument (including any financing or continuation statement or any filing under tax or securities laws) or any
rerecording, refilling or re-registration thereof. 
  
 SECTION
8.04 Not Responsible for Recitals or Issuance of Securities. The recitals contained herein and in the Trust Securities Certificates shall be taken as the statements of the Trust, and the Trustees do not assume any responsibility for their
correctness. The Trustees shall not be accountable for the use or application by the Trust of the proceeds of the Trust Securities in accordance with Section 2.05. 
  
 The Property Trustee may conclusively assume that any funds held by it hereunder are legally available unless an officer of
the Property Trustee assigned to its Institutional Trust Services Department shall have received written notice from the Company, any Holder or any other Trustee that such funds are not legally available. 
  

 38 

 SECTION 8.05 May Hold Securities. Except as provided in the definition of the term
“Outstanding” in Article I, any Trustee or any other agent of the Trustees or the Trust, in its individual or any other capacity, may become the owner or pledgee of Trust Securities and may otherwise deal with the Trust with the same
rights it would have if it were not a Trustee or such other agent. 
  
 SECTION 8.06 Compensation; Fees; Indemnity. The Depositor agrees: 
  
 (i) to pay to the Trustees from time to time reasonable compensation for all services rendered by the Trustees hereunder (which
compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 
  
 (ii) except as otherwise expressly provided herein, to reimburse the Trustees upon request for all reasonable expenses, disbursements and
advances incurred or made by the Trustees in accordance with any provision of this Trust Agreement (including the reasonable compensation and the expenses and disbursements of their agents and counsel), except any such expense, disbursement or
advance as may be attributable to their negligence or willful misconduct (or, in the case of the Administrative Trustees or the Delaware Trustee, any such expense, disbursement or advance as may be attributable to its, his or her gross negligence,
bad faith or willful misconduct); and 
  
 (iii)
to indemnify each of the Trustees (and any predecessor Trustees) for, and to hold the Trustees harmless against, any and all loss, damage, claims, liability or expense incurred without gross negligence or willful misconduct on its part arising out
of or in connection with the acceptance or administration of this Trust Agreement, including the costs and expenses of defending themselves against any claim or liability in connection with the exercise or performance of any of their powers or
duties hereunder except any such expense, disbursement or advance as may be attributable to such Trustee’s gross negligence or willful misconduct (or, in the case of the Administrative Trustees or the Delaware Trustee, any such expense,
disbursement or advance as may be attributable to its, his or her gross negligence or willful misconduct). 
  
 The provisions of this Section 8.06 shall survive the termination of this Trust Agreement or the resignation or removal of any Trustee. 
  
 In addition to and without prejudice to its rights hereunder, when the
Property Trustee incurs expenses or renders services after a Bankruptcy Event with respect to the Depositor or the Trust occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any
applicable federal or state bankruptcy, receivership, insolvency or similar law. 
  
 No trustee may claim any Lien or charge on any Trust Property as a result of any amount due pursuant to this Section 8.06. 
  
 SECTION 8.07 Trustees Required; Eligibility. 
  
 (a) There shall at all times be a Property Trustee hereunder with respect to the Trust Securities. The Property Trustee shall be a Person
that has a combined capital and surplus of at least $50,000,000. If any such Person publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Property Trustee with respect to the Trust
Securities shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 
  

 39 

 (b) There shall at all times be one or more Administrative Trustees hereunder with
respect to the Trust Securities. Each Administrative Trustee shall be either a natural person who is at least 21 years of age or a legal entity that shall act through one or more persons authorized to bind such entity. 
  
 (c) There shall at all times be a Delaware Trustee with
respect to the Trust Securities. The Delaware Trustee shall either be (i) a natural person who is at least 21 years of age and a resident of the State of Delaware or (ii) a legal entity authorized to conduct a trust business and with its principal
place of business in the State of Delaware that shall act through one or more persons authorized to bind such entity. 
  
 SECTION 8.08 Conflicting Interests. If the Property Trustee has or shall acquire a conflicting interest within the meaning of Section 310(b) of the
Trust Indenture Act, the Property Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, Section 310(b) of the Trust Indenture Act and this Trust Agreement;
provided, however, that there shall be excluded from the operation of Section 310(b)(1) of the Trust Indenture Act (i) the Guarantee and (ii) any indenture or indentures under which other securities or certificates of interest or
participation in other securities of the Trust or the Depositor are outstanding if the requirements for such exclusion set forth in Section 310(b)(1) of the Trust Indenture Act are met. Nothing herein shall preclude the Property Trustee from
submitting an application or applications contemplated by the second to the last paragraph of Section 310(b) of the Trust Indenture Act. 
  
 SECTION 8.09 Co-Trustees and Separate Trustee. 
  
 (a) At any time or times, for the purpose of meeting the legal requirements of the Trust Indenture Act or of any jurisdiction in which any
part of the Trust Property may at the time be located, the Holder of the Common Securities and the Property Trustee shall have power to appoint, and upon the written request of the Property Trustee, the Depositor shall for such purpose join with the
Property Trustee in the execution, delivery and performance of all instruments and agreements necessary or proper to appoint, one or more Persons approved by the Property Trustee either to act as co-trustee, jointly with the Property Trustee, of all
or any part of such Trust Property, or to act as separate trustee of any such Trust Property, in either case with such powers as may be provided in the instrument of appointment, and to vest in such Person or Persons in the capacity aforesaid, any
property, title, right or power deemed necessary or desirable, subject to the other provisions of this Section. If the Depositor does not join in such appointment within 15 days after the receipt by it of a request so to do, or in case an Event of
Default has occurred and is continuing, the Property Trustee alone shall have power to make such appointment. Any co-trustee or separate trustee appointed pursuant to this Section shall satisfy the requirements of Section 8.07. 
  
 (b) Should any written instrument from the Depositor be
required by any co-trustee or separate trustee so appointed for more fully confirming to such co-trustee or separate trustee such property, title, right, or power, any and all such instruments shall, on request, be executed, acknowledged, and
delivered by the Depositor. 
  
 (c) Every
co-trustee or separate trustee shall, to the extent permitted by law, but to such extent only, be appointed subject to the following terms, namely: 
  
 (i) The Trust Securities shall be executed and delivered and all rights, powers, duties, and obligations hereunder in respect of the
custody of securities, cash and other personal property held by, or required to be deposited or pledged with, the Trustees hereunder, shall be exercised, solely by the Trustees. 
  

 40 

 (ii) The rights, powers, duties, and obligations hereby conferred or imposed upon the
Property Trustee in respect of any property covered by such appointment shall be conferred or imposed upon and exercised or performed by the Property Trustee or by the Property Trustee and such co-trustee or separate trustee jointly, as shall be
provided in the instrument appointing such co-trustee or separate trustee, except to the extent that under any law of any jurisdiction in which any particular act is to be performed, the Property Trustee shall be incompetent or unqualified to
perform such act, in which event such rights, powers, duties, and obligations shall be exercised and performed by such co-trustee or separate trustee. 
  
 (iii) The Property Trustee at any time, by an instrument in writing executed by it, with the written concurrence of the Depositor, may
accept the resignation of or remove any co-trustee or separate trustee appointed under this Section, and, in case an Event of Default has occurred and is continuing, the Property Trustee shall have power to accept the resignation of, or remove, any
such co-trustee or separate trustee without the concurrence of the Depositor. Upon the written request of the Property Trustee, the Depositor shall join with the Property Trustee in the execution, delivery, and performance of all instruments and
agreements necessary or proper to effectuate such resignation or removal. A successor to any co-trustee or separate trustee so resigned or removed may be appointed in the manner provided in this Section. 
  
 (iv) No co-trustee or separate trustee hereunder shall be
personally liable by reason of any act or omission of the Property Trustee, or any other such trustee hereunder. 
  
 (v) The Trustees shall not be liable by reason of any act of a co-trustee or separate trustee. 
  
 (vi) Any Act of Holders delivered to the Property Trustee
shall be deemed to have been delivered to each such co-trustee and separate trustee. 
  
 SECTION 8.10 Resignation and Removal; Appointment of Successor. 
  
 (a) No resignation or removal of any Trustee (the “Relevant Trustee”) and no appointment of a successor Relevant Trustee
pursuant to this Article shall become effective until the acceptance of appointment by the successor Relevant Trustee in accordance with the applicable requirements of Section 8.11. 
  
 (b) The Relevant Trustee may resign at any time by giving written notice thereof to the Holders. If the
instrument of acceptance by a successor Relevant Trustee required by Section 8.11 shall not have been delivered to the Relevant Trustee within 30 days after the giving of such notice of resignation, the resigning Relevant Trustee may petition any
court of competent jurisdiction for the appointment of a successor Relevant Trustee. 
  
 (c) Unless an Event of Default shall have occurred and be continuing, the Relevant Trustee may be removed at any time by Act of the Holder
of the Common Securities. If an Event of Default shall have occurred and be continuing, the Relevant Trustee may be removed at such time by Act of the Holders of a majority in Liquidation Amount of the Trust PIERS, delivered to the Relevant Trustee
(in its individual capacity and on behalf of the Trust). 
  
 (d) If the Relevant Trustee shall resign, be removed or become incapable of continuing to act as Trustee at a time when no Event of Default shall have occurred and be continuing, the Holder of the Common Securities,
by Act of the Holder of the Common Securities delivered to the retiring Relevant Trustee, shall promptly appoint a successor Relevant Trustee or Trustees, and the 

  

 41 

 
retiring Relevant Trustee shall comply with the applicable requirements of Section 8.11. If the Relevant Trustee shall resign, be removed or become incapable
of continuing to act as the Relevant Trustee at a time when an Event of Default shall have occurred and be continuing, the Holders of Trust PIERS, by Act of the Holders of a majority in Liquidation Amount of the Trust PIERS then outstanding
delivered to the retiring Relevant Trustee, shall promptly appoint a successor Relevant Trustee or Trustees, and the Relevant Trustee shall comply with the applicable requirements of Section 8.11. If no successor Relevant Trustee shall have been so
appointed in accordance with this Section 8.10 and accepted appointment in the manner required by Section 8.11, any Holder who has been a Holder of Trust Securities for at least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the appointment of a successor Relevant Trustee. 
  
 (e) The retiring Relevant Trustee shall give notice of each resignation and each removal of the Relevant Trustee, and each appointment of
a successor Trustee to all Holders in the manner provided in Section 10.07 and shall give notice to the Depositor. Each notice shall include the name of the successor Relevant Trustee and the address of its Corporate Trust Office if it is the
Property Trustee. 
  
 (f) Notwithstanding the
foregoing or any other provision of this Trust Agreement, in the event any Administrative Trustee or a Delaware Trustee who is a natural person dies or becomes incompetent or incapacitated, the vacancy created by such death, incompetence or
incapacity may be filled by (i) the act of the remaining Administrative Trustee or (ii) otherwise by the Depositor (with the successor in each case being an individual who satisfies the eligibility requirement for Administrative Trustees set forth
in Section 8.07). Additionally, notwithstanding the foregoing or any other provision of this Trust Agreement, in the event the Depositor believes that any Administrative Trustee has become incompetent or incapacitated, the Depositor, by notice to
the remaining Trustees, may terminate the status of such Person as an Administrative Trustee (in which case the vacancy so created will be filled in accordance with the preceding sentence). 
  
 SECTION 8.11 Acceptance of Appointment by Successor. 
  
 (a) In case of the appointment hereunder of a successor
Relevant Trustee, every such successor Relevant Trustee so appointed shall execute, acknowledge and deliver to the Trust and to the retiring Relevant Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the
retiring Relevant Trustee shall become effective and such successor Relevant Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Relevant Trustee; but, on the
request of the Depositor or the successor Relevant Trustee, such retiring Relevant Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Relevant Trustee all the rights, powers and trusts of the
retiring Relevant Trustee and shall duly assign, transfer and deliver to such successor Relevant Trustee all property and money held by such retiring Relevant Trustee hereunder. 
  
 (b) Upon request of any such successor Relevant Trustee, the Trust shall execute any and all instruments for
more fully and certainly vesting in and confirming to such successor Relevant Trustee all such rights, powers and trusts referred to in the preceding paragraph. 
  
 (c) No successor Relevant Trustee shall accept its appointment unless at the time of such acceptance such
successor Relevant Trustee shall be qualified and eligible under this Article. 
  
 SECTION 8.12 Merger, Conversion, Consolidation or Succession to Business. Any Person into which the Property Trustee, Delaware Trustee or any Administrative Trustee which is not a natural person may be merged
or converted or with which it may be consolidated, or any Person resulting from 

  

 42 

 
any merger, conversion or consolidation to which such Relevant Trustee shall be a party, or any Person succeeding to all or substantially all the corporate
trust business of such Relevant Trustee, shall be the successor of such Relevant Trustee hereunder, provided such Person shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on
the part of any of the parties hereto. 
  
 SECTION 8.13
Preferential Collection of Claims Against Depositor or Trust. If and when the Property Trustee shall be or become a creditor of the Depositor or the Trust (or any other obligor upon the Convertible Debentures or the Trust Securities), the
Property Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Depositor or Trust (or any such other obligor). 
  
 SECTION 8.14 Reports by Property Trustee. 
  
 (a) Within 60 days after June 1 of each year commencing with June 1, 2004, if required by Section 313(a) of
the Trust Indenture Act, the Property Trustee shall transmit a brief report dated as of such June 1 with respect to any of the events specified in such Section 313(a) that may have occurred since the later of the date of this Trust Agreement or the
preceding June 1. 
  
 (b) The Property Trustee
shall transmit to Holders the reports required by Section 313(b) of the Trust Indenture Act at the times specified therein.

Trust Indenture Act. 
  
 SECTION 8.15 Reports to the Property
Trustee. The Depositor and the Administrative Trustees on behalf of the Trust shall provide to the Property Trustee such documents, reports and information as required by Section 314 of the Trust Indenture Act (if any) and the compliance
certificate required by Section 314(a)(4) of the Trust Indenture Act in the form and in the manner required by Section 314 of the Trust Indenture Act. Delivery of such documents, reports and information are for information purposes only and the
Property Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including compliance with any covenants hereunder (as to which the Property
Trustee is entitled to rely exclusively on an Officers’ Certificate). 
  
 SECTION 8.16 Evidence of Compliance with Conditions Precedent. Each of the Depositor and the Administrative Trustees on behalf of the Trust shall provide to the Property Trustee such evidence of compliance with
any conditions precedent, if any, provided for in this Trust Agreement that relate to any of the matters set forth in Section 314(c) of the Trust Indenture Act. Any certificate or opinion required to be given pursuant to Section 314(c)(1) of the
Trust Indenture Act shall comply with Section 314(e) of the Trust Indenture Act. 
  
 SECTION 8.17 Number of Trustees. 
  
 (a) The number of Trustees shall initially be four, provided that the Depositor by written instrument may increase or decrease the number of Administrative Trustees. 
  
 (b) If a Trustee ceases to hold office for any reason and
the number of Administrative Trustees is not reduced pursuant to Section 8.17(a), or if the number of Trustees is increased pursuant to Section 8.17(a), a vacancy shall occur. The vacancy shall be filled with a Trustee appointed in accordance with
Section 8.10. 
  

 43 

 (c) The death, resignation, retirement, removal, bankruptcy, incompetence or incapacity
to perform the duties of a Trustee shall not operate to annul the Trust. Whenever a vacancy in the number of Administrative Trustees shall occur, until such vacancy is filled by the appointment of an Administrative Trustee in accordance with Section
8.10, the Administrative Trustees in office, regardless of their number (and notwithstanding any other provision of this Trust Agreement), shall have all powers granted to the Administrative Trustees and shall discharge the duties imposed upon the
Administrative Trustees by this Trust Agreement. 
  
 SECTION 8.18
Delegation of Power. 
  
 (a) Any
Administrative Trustee may, by power of attorney consistent with applicable law, delegate to any other natural person over the age of 21 his or her power for the purpose of executing any documents contemplated in Section 2.07(a)(i), including any
registration statement or amendment thereto filed with the Commission, or making any other governmental filing; and 
  
 (b) The Administrative Trustees shall have power to delegate from time to time to such of their number the doing of such things and the
execution of such instruments either in the name of the Trust or the names of the Administrative Trustees or otherwise as the Administrative Trustees may deem expedient, to the extent such delegation is not prohibited by applicable law or contrary
to the provisions of the Trust, as set forth herein. 
  
 SECTION
8.19 Voting. Except as otherwise provided in this Trust Agreement, the consent or approval of the Administrative Trustees shall require consent or approval by not less than a majority of the Administrative Trustees, unless there are only two,
in which case both must consent. 
  
 SECTION 8.20 Enforcement
of Rights of Property Trustee by Holders. If an Event of Default occurs and is continuing, then the Holders of Trust PIERS will rely on the enforcement by the Property Trustee of its rights against the Depositor as the holder of the Convertible
Debentures. In addition, the Holders of a majority in aggregate Liquidation Amount of the Trust PIERS will have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the Property Trustee or to
direct the exercise of any trust or power conferred upon the Property Trustee under this Trust Agreement, including the right to direct the Property Trustee to exercise the remedies available to it as a holder of the Convertible Debentures, provided
that such direction shall not be in conflict with any rule of law or with this Trust Agreement, and could not involve the Property Trustee in personal liability in circumstances where reasonable indemnity would not be adequate. If the Property
Trustee fails to enforce its rights under the Convertible Debentures, a Holder of Trust PIERS may, to the fullest extent permitted by applicable law, institute a legal proceeding against the Depositor to enforce its rights under this Trust Agreement
without first instituting any legal proceeding against the Property Trustee or any other Person, including the Trust; it being understood and intended that no one or more of such Holders shall have any right in any manner whatsoever by virtue of, or
by availing of, any provision of this Trust Agreement to affect, disturb or prejudice the rights of any other of such Holders or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this
Trust Agreement, except in the manner herein provided and for the equal and ratable benefit of all such Holders. Notwithstanding the foregoing, a Holder of Trust PIERS may institute a legal proceeding directly against the Depositor, without first
instituting a legal proceeding against or requesting or directing that action be taken by the Property Trustee or any other Person, for enforcement of payment to such Holder of principal of or interest on the Convertible Debentures having a
principal amount equal to the aggregate stated liquidation amount of the Trust PIERS of such Holder on or after the due dates therefor specified or provided for in the Convertible Debentures. The Depositor shall be subrogated to all rights of the
Holders of Trust PIERS in respect of any amounts paid to such Holders by the Depositor pursuant to this Section 8.20.

 (a) If any Early Termination Event specified in clause (a),
(b), (d) and (e) of Section 9.02 occurs, the Trust shall be dissolved and the Property Trustee shall distribute the Convertible Debentures to the Holders as provided in this Section 9.05. Such dissolution and distribution shall be 

  

 45 

 
conditioned, however, on the Administrative Trustees’ receipt of an opinion of independent counsel to the effect that Holders will not recognize any
gain or loss for United States federal income tax purposes as a result of the dissolution of the Trust and the distribution of the Convertible Debentures. 
  
 (b) In connection with a distribution of the Convertible Debentures, each Holder of Trust Securities shall be entitled to receive, after
the satisfaction of liabilities to creditors of the Trust (as evidenced by a certificate of the Administrative Trustees), a Like Amount of Convertible Debentures on a pro rata basis. Notice of liquidation shall be given by the Trustees by
first-class mail, postage prepaid, mailed not later than 30 nor more than 60 days prior to the Liquidation Date to each Holder of Trust Securities at such Holder’s address appearing in the Securities Register. All notices of liquidation shall:

  
 (i) state the Liquidation Date; 

 
 (ii) state that from and after the Liquidation Date, the
Trust Securities will no longer be deemed to be Outstanding and any Trust Securities Certificates not surrendered for exchange will be deemed to represent a Like Amount of Convertible Debentures; and 
  
 (iii) provide such information with respect to the mechanics
by which Holders may exchange Trust Securities Certificates for Convertible Debentures as the Administrative Trustees or the Property Trustee shall deem appropriate. 
  
 (c) In order to effect the liquidation of the Trust and distribution of the Convertible Debentures to
Holders, the Property Trustee shall establish a record date for such distribution (which shall be not more than 45 days prior to the Liquidation Date) and, either itself acting as exchange agent or through the appointment of a separate exchange
agent, shall establish such procedures as it shall deem appropriate to effect the distribution of Convertible Debentures in exchange for the Outstanding Trust Securities Certificates. 
  
 (d) Except where Section 9.02(c), 9.02(f) or 9.05(f) applies, after the Liquidation Date, (i) the Trust
Securities will no longer be deemed to be Outstanding, (ii) if the Trust Securities are represented by one or more global certificates, DTC or its nominee, as a record holder of Trust Securities, will receive a registered global certificate or
certificates representing the Convertible Debentures to be delivered upon liquidation of the Trust, (iii) any Trust Securities Certificates not held by DTC or its nominee will be deemed to represent a Like Amount of Convertible Debentures, bearing
accrued and unpaid interest in an amount equal to the accumulated and unpaid distribution on such Trust Securities, until such Trust Securities Certificates are presented for cancellation, whereupon the Depositor will issue to the Holder, and the
Indenture Trustee will authenticate, a certificate representing the such Convertible Debentures and (iv) all rights of Holders holding Trust Securities will cease, except the right of such Holders to receive Convertible Debentures upon surrender of
Trust Securities Certificates. 
  
 (e) The
Depositor will use its reasonable efforts to have the Convertible Debentures that are distributed in exchange for the Trust PIERS to be listed on such securities exchange as the Trust PIERS are then listed. The Depositor may elect to have the
Convertible Debentures issued in book-entry form to the Clearing Agency or its nominee. 
  
 (f) In the event that, notwithstanding the other provisions of this Section 9.05, whether because of an order for dissolution entered by a
court of competent jurisdiction or otherwise, distribution of the Convertible Debentures in the manner provided herein is determined by the Administrative Trustees not to be practical, in which event the Holders will be entitled to receive out of
the assets of the Trust available for distribution to Holders, after satisfaction of liabilities to creditors, an amount equal to the Liquidation Amount per Trust Security plus accrued and unpaid Distributions, 

  

 46 

 
including Contingent Distributions, thereon to the date of payment (such amount being the “Liquidation Distribution”). If such Liquidation
Distribution can be paid only in part because the Trust has insufficient assets available to pay in full the aggregate Liquidation Distribution, then, subject to the next succeeding sentence, the amounts payable by the Trust on the Trust Securities
shall be paid on a pro rata basis (based upon Liquidation Amounts). The Holder of the Common Securities will be entitled to receive Liquidation Distributions upon any such dissolution, winding-up or termination pro rata (determined as aforesaid)
with Holders of Trust PIERS, except that, if an Event of Default has occurred and is continuing, the Trust PIERS shall have a priority over the Common Securities. 
  
 SECTION 9.06 Mergers and Consolidations of the Trust. The Trust may not consolidate, merge with or into, or be
replaced by, or convey, transfer or lease its properties and assets substantially as an entirety to any corporation or other body, except pursuant to Sections 9.02 and 9.05. The Trust may at the request of the Company, with the consent of a majority
of the Administrative Trustees and without the consent of the Holders of the Trust Securities, the Delaware Trustee or the Property Trustee, consolidate, merge with or into, or be replaced by, or convey, or lease its properties or assets
substantially as an entirety to, another trust organized as such under the laws of any state; provided, that (i) such successor entity either (x) expressly assumes all of the obligations of the Trust with respect to the Trust Securities or
(y) substitutes for the Trust PIERS other securities having substantially the same terms as the Trust Securities (herein referred to as the “Successor Securities”) so long as the Successor Securities rank the same as the Trust
Securities rank in priority with respect to distributions and payments upon liquidation, redemption and otherwise, (ii) the Depositor expressly appoints a trustee of such successor entity possessing the same powers and duties as the Property Trustee
as the holder of legal title to the Convertible Debentures, (iii) the Trust PIERS or any Successor Securities are listed, or any Successor Securities will be listed upon notification of issuance, on any national securities exchange or other
organization on which the Trust PIERS are then listed, (iv) such merger, consolidation or replacement does not cause the Trust PIERS (including any Successor Securities) to be downgraded by any nationally recognized rating, agency (v) such merger,
consolidation or replacement does not adversely affect the rights, preferences and privileges of the Holders of the Trust Securities (including any Successor Securities) in any material respect, other than with respect to any dilution of the
holders’ interest in the new entity, (vi) such successor entity has a purpose substantially identical to that of the Trust, (vii) prior to such merger, consolidation or replacement, the Depositor has received an Opinion of Counsel to the effect
that (A) such merger, consolidation or replacement does not adversely affect the rights, preferences and privileges of the Holders of the Trust Securities (including any Successor Securities) in any material respect, other than with respect to any
dilution of the Holders’ interest in the new entity, and (B) following such merger, consolidation or replacement, neither the Trust nor such successor entity will be required to register as an investment company under the Investment Company Act
of 1940, and (viii) the Depositor guarantees the obligations of such successor entity under the Successor Securities at least to the extent provided by the Guarantee. Notwithstanding the foregoing, the Trust shall not, except with the consent of
Holders of 100% in Liquidation Amount of the Trust Securities, consolidate, merge with or into, or be replaced by any other entity or permit any other entity to consolidate, merge with or into, or replace it if, in the opinion of tax counsel, such
consolidation, merger or replacement would cause the Trust or the successor entity to be classified as other than a grantor trust for federal income tax purposes. 
  
 SECTION 9.07 Notification. The Delaware Trustee will be notified in writing of the completion of the winding up of
the Trust in accordance with the Statutory Trust Act and Section 9.03 hereof and the filing of the certificate of cancellation with the Secretary of State of the State of Delaware.

Security shall not operate to terminate this Trust Agreement, nor entitle the legal representatives or heirs of such Person or any Holder for such Person, to claim an accounting, take any action or bring any proceeding in and for a partition or
winding up of the arrangements contemplated hereby, nor otherwise affect the rights, obligations and liabilities of the parties hereto or any of them.

or questions arising under this Trust Agreement, which shall not be inconsistent with the other provisions of this Trust Agreement, or (ii) to modify, eliminate or add to any provisions of this Trust Agreement to such extent as shall be necessary to
ensure that the Trust will not be classified as other than a grantor trust for United States federal income tax purposes at any time that any Trust Securities are outstanding, or to ensure that the Trust will not be required to register as an
investment company under the Investment Company Act of 1940, or to conform to any change in the Investment Company Act of 1940 or the Trust Indenture Act or the rules and regulations under either law; provided, however, that, except in

 (b) Except as provided in Section 10.02(c) hereof, any
provision in this Trust Agreement may be amended by the Trust or the Property Trustee with (i) the consent of Trust Holders representing a majority (based upon Liquidation Amounts) of the Trust Securities then Outstanding and (ii) receipt by the
Property Trustee of an Opinion of Counsel to the effect that such amendment or the exercise of any power granted to the Property Trustee in accordance with such amendment will not affect the Trust’s status as a grantor trust for United States
federal income tax purposes or the Trust’s exemption from status of an “investment company” under the Investment Company Act of 1940, as amended. 
  
 (c) In addition to and notwithstanding any other provision in this Trust Agreement, without the consent of

of Control, (v) change the right of any Holder of Trust PIERS to convert its Trust PIERS upon the occurrence of the events set forth in Section 4.03 and at the conversion ratio, as adjusted, or (vi) modify the provisions of this Section 10.02. Any
amendment of the Trust Agreement will become effective when notice of the amendment is given to the Holders; provided, however, that a majority in aggregate Liquidation Amount may consent to reduce the redemption notice period to not
less than five days. 
  

 48 

 (d) Notwithstanding any other provisions of this Trust Agreement, the Property Trustee
shall not enter into or consent to any amendment to this Trust Agreement which would cause the Trust to fail or cease to qualify for the exemption from status of an “investment company” under the Investment Company Act of 1940, or cease to
be classified as a grantor trust for United States Federal income tax purposes. 
  
 (e) Without the consent of the Depositor, this Trust Agreement may not be amended in a manner which imposes any additional obligation on
the Depositor. In executing any amendment permitted by this Trust Agreement, the Property Trustee shall be entitled to receive, and (subject to Section 8.01) shall be fully protected in relying upon an Opinion of Counsel stating that the execution
of such amendment is authorized or permitted by this Trust Agreement. Any Property Trustee may, but shall not be obligated to, enter into any such amendment which affects such Property Trustee’s own rights, duties, immunities or liabilities
under this Trust Agreement or otherwise. 
  
 (f)
In the event that any amendment to this Trust Agreement is made, the Administrative Trustees shall promptly provide to the Depositor a copy of such amendment.

 THIS CERTIFICATE IS NOT TRANSFERABLE EXCEPT AS PROVIDED IN THE TRUST 
 AGREEMENT REFERRED
TO HEREIN  
  
 Certificate Evidencing Common Securities

  
 of 
  
 Omnicare Capital Trust II 
  
 Common Securities 
 (liquidation amount $50 per Common Security) 
  
 Omnicare Capital Trust II, a statutory trust formed under the laws of the State of Delaware (the “Trust”), hereby certifies that
             (the “Holder”) is the registered owner of              common securities of the Trust
representing undivided beneficial interests in the assets of the Trust designated the Common Securities (Liquidation Amount $50 per Common Security) (the “Common Securities”). Subject to the limitations in Section 5.12 of the Trust
Agreement (as defined below), the Common Securities are transferable on the books and records of the Trust, in person or by a duly authorized attorney, upon surrender of this certificate duly endorsed and in proper form for transfer. The
designation, rights, privileges, restrictions, preferences and other terms and provisions of the Common Securities represented hereby are issued and shall in all respects be subject to the provisions of the Amended and Restated Trust Agreement of
the Trust dated as of [            ], 2005, as the same may be amended from time to time (the “Trust Agreement”). Capitalized terms used but not defined herein shall
have the meaning given them in the Trust Agreement. The Depositor will provide a copy of the Trust Agreement, the Guarantee Agreement and the Subordinated Indenture (including any supplemental indenture) to the Holder without charge upon written
request to the Depositor at its principal place of business. 
  
 Upon receipt of this certificate, the Holder is bound by the Trust Agreement and is entitled to the benefits thereunder to the extent provided therein. 
  

By acceptance hereof, the Holder agrees to treat, for United States federal income tax purposes, the Convertible Debentures as indebtedness and the
Common Securities as evidence of indirect beneficial ownership in the Convertible Debentures. 
  

 IN WITNESS WHEREOF, the Trust has executed this certificate this
             day of [            ], 2005.

 [FORM OF REVERSE OF SECURITY] 
  
 Distributions payable on each Trust Common Security will be fixed at a rate per annum of 4.00% (the “Coupon
Rate”) of the Liquidation Amount of $50 per Trust Common Security, such rate being the rate of interest payable on the Convertible Debentures to be held by the Property Trustee. Distributions on the Trust Securities on each Distribution
Date shall be payable to the Holders thereof as they appear on the Securities Register for the Trust Securities on the relevant record date, which shall be the close of business on (i) the Business Day prior to the relevant Distribution Date if the
Trust Common Securities are represented by book-entry certificates or (ii) if the Trust Common Securities are not in book-entry form and the Convertible Debentures are not in the form of a global certificate, the Depositor will have the right to
select record dates, which must be at least one business day before an interest payment date. Distributions payable on any Trust Common Securities that are not punctually paid on any distribution date will cease to be payable to the person in whose
name such Trust Common Securities are registered on the original record date, and such defaulted distribution will instead be payable to the person in whose name such Trust Common Securities are registered on the special record date or other
specified date determined in accordance with the Trust Agreement. A Distribution is payable only to the extent that payments are made in respect of the Convertible Debentures held by the Property Trustee and to the extent the Property Trustee has
funds on hand legally available therefor. 
  
 Distributions on the
Trust Common Securities shall be cumulative and shall accumulate from December 15, 2004 and will be payable quarterly in arrears, on March 15, June 15, September 15 and December 15 of each year, commencing on March 15, 2005, except as otherwise
described below. Distributions will be computed on the basis of a 360-day year consisting of twelve 30-day months; any period shorter than a full quarterly 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. 
  
 During any quarterly 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 quarterly period beginning June 15, 2009, the Trust will also pay contingent
distributions (“Contingent Distributions”) of 0.125% of the average of the Trading Price of the Trust PIERS if the average of such Trading Prices for the five consecutive Trading Days ending on the second Trading Day preceding such
quarterly period equals 115% or more of the stated liquidation amount of the Trust PIERS. 
  
 As long as no Default in the payment of interest, including contingent interest, if any, on the Convertible Debentures has occurred and is continuing under the Subordinated Indenture, the Depositor has the right under
the Subordinated Indenture to defer payments of interest (other than contingent interest) by extending the interest payment period at any time and from time to time on the Debentures for a period not exceeding 20 consecutive calendar quarterly
periods, including the first such quarterly period during such extension period (each an “Extension Period”); provided that no Extension Period shall extend beyond the stated maturity date of the Convertible Debentures or any
redemption date therefor. As a consequence of such deferral, Distributions (other than Contingent Distributions) will also be deferred. Despite such deferral, quarterly Distributions will continue to accumulate with interest thereon (to the extent
permitted by applicable law, but not at a rate exceeding the rate of interest then accruing on the Convertible Debentures) at the Coupon Rate compounded quarterly during any such Extension Period. Prior to the termination of any such Extension
Period, the Depositor may further defer payments of interest by further extending such Extension Period; provided that such Extension Period, together with all such previous and further extensions within such Extension Period, may not exceed
20 consecutive quarterly periods, including the first quarterly period during such Extension Period, extend beyond the stated maturity date of the Convertible Debentures or any redemption date therefor. Payments of accumulated Distributions will be
payable to Holders as they appear on the books and records of the Trust 

  

 A-3 

 
on the first record date after the end of the Extension Period. Upon the termination of any Extension Period and the payment of all amounts then due, the
Depositor may commence a new Extension Period, subject to the above requirements. The payment of Contingent Distributions may not, under any circumstances, be subject to an Extension Period. 
  
 The Property Trustee may, at the direction of the Depositor, at any time
liquidate the Trust and cause the Debentures to be distributed to the holders of the Trust Securities in liquidation of the Trust or, simultaneously with any redemption of the Debentures, cause a Like Amount of the Trust Securities to be redeemed by
the Trust. 
  
 Under certain circumstances, the right of the
holders of the Common Securities shall be subordinate to the rights of the holders of the Trust PIERS, as provided in the Trust Agreement. 
  
 The Common Securities shall be redeemable as provided in the Trust Agreement.

 WHEREAS, the Trust intends to issue its Common Securities (the “Common Securities”) to and receive
Convertible Debentures from the Company and to issue and sell Omnicare Capital Trust II Series B 4% Trust PIERS (the “Trust PIERS”) with such powers, preferences and special rights and restrictions as are set forth in the Trust
Agreement; and 
  
 WHEREAS, the Company is the issuer of the
Convertible Debentures. 
  
 NOW, THEREFORE, in consideration of
the purchase by each Holder of the Trust PIERS, which purchase the Company hereby agrees shall benefit the Company and which purchase the Company acknowledges will be made in reliance upon the execution and delivery of this Agreement, the Company
and the Trust hereby agree as follows: 
  
 ARTICLE I

  
 Section 1.01. Guarantee by the Company. Subject to
the terms and conditions hereof, the Company hereby irrevocably and unconditionally guarantees to each person or entity to whom the Trust is now or hereafter becomes indebted or liable (the “Beneficiaries”) the full payment, when
and as due, of any and all Obligations (as hereinafter defined) to such Beneficiaries. As used herein, “Obligations” means any indebtedness, expenses or liabilities of the Trust, other than obligations of the Trust to pay to Holders of any
Trust PIERS or other similar interests in the Trust the amounts due such Holders pursuant to the terms of the Trust PIERS. This Agreement is intended to be for the benefit of, and to be enforceable by, all such Beneficiaries, whether or not such
Beneficiaries have received notice hereof. 
  
 Section 1.02.
Term of Agreement. This Agreement shall terminate and be of no further force and effect upon the date on which there are no Beneficiaries remaining; provided, however, that this Agreement shall continue to be effective or shall
be reinstated, as the case may be, if at any time any Holder of Trust PIERS or any Beneficiary must restore payment of any sums paid under the Trust PIERS, under any Obligation, under the Guarantee Agreement dated the date hereof by the Company and
JPMorgan Chase Bank, as guarantee trustee, or under this Agreement for any reason whatsoever. Except as set forth in this Section 1.02, this Agreement is continuing, irrevocable, unconditional and absolute. 
  
 Section 1.03. Waiver of Notice. The Company hereby waives notice of
acceptance of this Agreement and of any Obligation to which it applies or may apply, and the Company hereby waives presentment, demand for payment, protest, notice of nonpayment, notice of dishonor, notice of redemption and all other notices and
demands. 
  

 Section 1.04. No Impairment. The obligations, covenants, agreements and duties of the Company
under this Agreement shall in no way be affected or impaired by reason of the happening from time to time of any of the following: 
  
 (a) the extension of time for the payment by the Trust of all or any portion of the Obligations or for the performance of any other
obligation under, arising out of, or in connection with, the Obligations; 
  
 (b) any failure, omission, delay or lack of diligence on the part of the Beneficiaries to enforce, assert or exercise any right, privilege, power or remedy conferred on the Beneficiaries with respect to the
Obligations or any action on the part of the Trust granting indulgence or extension of any kind; or 
  
 (c) the voluntary or involuntary liquidation, dissolution, sale of any collateral, receivership, insolvency, bankruptcy, assignment for
the benefit of creditors, reorganization, arrangement, composition or readjustment of debt of, or other similar proceedings affecting, the Trust or any of the assets of the Trust. 
  
 There shall be no obligation of the Beneficiaries to give notice to, or obtain the consent of, the Company with respect to
the happening of any of the foregoing. 
  
 Section 1.05.
Enforcement. A Beneficiary may enforce this Agreement directly against the Company and the Company waives any right or remedy to require that any action be brought against the Trust or any other person or entity before proceeding against the
Company. 
  
 Section 1.06. Subrogation. The Company shall
be subrogated to all rights (if any) of the Trust in respect of any amounts paid to the Beneficiaries by Omnicare under this Agreement; provided, however, that the Company shall not (except to the extent required by mandatory
provisions of law) be entitled to enforce or exercise any rights which it may acquire by way of subrogation or any indemnity, reimbursement or other agreement, in all cases as a result of payment under this Agreement, if, at the time of any such
payment, any amounts are due and unpaid under this Agreement. 
  
 ARTICLE II 
  
 Section 2.01. Binding
Effect. All guarantees and agreements contained in this Agreement shall bind the successors, assigns, receivers, trustees and representatives of the Company and shall inure to the benefit of the Beneficiaries.

any Trust PIERS of any series are outstanding, this Agreement shall not be modified or amended in any manner adverse to such Beneficiary or to the Holders of the Trust PIERS.

 [FORM OF REVERSE OF SECURITY] 
  
 Distributions payable on each Trust PIERS will be fixed at a rate per annum of 4.00% (the “Coupon Rate”) of
the liquidation amount of $50 per Trust PIERS, such rate being the rate of interest payable on the Convertible Debentures to be held by the Property Trustee. Distributions on the Trust PIERS on each Distribution Date shall be payable to the Holders
thereof as they appear on the Securities Register for the Trust PIERS on the relevant record date, which shall be the close of business on (i) the Business Day prior to the relevant Distribution Date if the Trust PIERS are represented by Book-Entry
Trust PIERS Certificates or (ii) if the Trust PIERS do not remain in book-entry form and the Convertible Debentures are not in the form of a global certificate, the Depositor will have the right to select record dates, which must be at least one
business day before an interest payment date. Distributions payable on any Trust PIERS that are not punctually paid on any distribution date will cease to be payable to the person in whose name such Trust PIERS are registered on the original record
date, and such defaulted distribution will instead be payable to the person in whose name such Trust PIERS are registered on the special record date or other specified date determined in accordance with the Trust Agreement. A Distribution is payable
only to the extent that payments are made in respect of the Debentures held by the Property Trustee and to the extent the Property Trustee has funds on hand legally available therefor. 
  
 Distributions on the Trust PIERS shall be cumulative and shall accumulate from December 15, 2004 and will be payable
quarterly in arrears, on March 15, June 15, September 15 and December 15 of each year, commencing on March 15, 2005, except as otherwise described below. Distributions will be computed on the basis of a 360-day year consisting of twelve 30-day
months; any period shorter than a full quarterly 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. 
  
 During any quarterly 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 quarterly period beginning June 15, 2009, the Trust will also pay contingent distributions (“Contingent Distributions”) of 0.125% of the average of the
Trading Price of the Trust PIERS if the average of such Trading Prices for the five consecutive Trading Days ending on the second Trading Day preceding such quarterly period equals 115% or more of the stated liquidation amount of the Trust PIERS.

  
 As long as no Default in the payment of interest, including
contingent interest, if any, on the Convertible Debentures has occurred and is continuing under the Subordinated Indenture, the Depositor has the right under the Subordinated Indenture to defer payments of interest (other than contingent interest)
by extending the interest payment period at any time and from time to time on the Debentures for a period not exceeding 20 consecutive calendar quarterly periods, including the first such quarterly period during such extension period (each an
“Extension Period”); provided that no Extension Period shall extend beyond the stated maturity date of the Convertible Debentures or any redemption date therefor. As a consequence of such deferral, Distributions (other than
Contingent Distributions) will also be deferred. Despite such deferral, quarterly Distributions will continue to accumulate with interest thereon (to the extent permitted by applicable law, but not at a rate exceeding the rate of interest then
accruing on the Debentures) at the Coupon Rate compounded quarterly during any such Extension Period. Prior to the termination of any such Extension Period, the Depositor may further defer payments of interest by further extending such Extension
Period; provided that such Extension Period, together with 

  

 
all such previous and further extensions within such Extension Period, may not exceed 20 consecutive quarterly periods, including the first quarterly period
during such Extension Period, extend beyond the stated maturity date of the Convertible Debentures or any redemption date therefor. Payments of accumulated Distributions will be payable to Holders as they appear on the books and records of the Trust
on the first record date after the end of the Extension Period. Upon the termination of any Extension Period and the payment of all amounts then due, the Depositor may commence a new Extension Period, subject to the above requirements. The payment
of Contingent Distributions may not, under any circumstances, be subject to an Extension Period. 
  
 The Property Trustee may, at the direction of the Depositor, at any time liquidate the Trust and cause the Convertible Debentures to be distributed to the
holders of the Trust Securities in liquidation of the Trust or, simultaneously with any redemption of the Convertible Debentures, cause a Like Amount of the Trust Securities to be redeemed by the Trust. 
  
 The Trust PIERS shall be redeemable as provided in the Trust Agreement. If a
Change of Control occurs, each holder of Trust PIERS will have the right to require the Depositor to purchase all or any part of that Holder’s Trust PIERS at a purchase price equal to 100% of the Trust PIERS repurchased plus accrued and unpaid
Distributions, including Contingent Distributions, if any, on the Trust PIERS repurchased, to the date of purchase on the terms and conditions set forth in the Trust Agreement. 
  
 SUBJECT TO AND UPON COMPLIANCE WITH THE PROVISIONS OF THE TRUST AGREEMENT, THE TRUST PIERS ARE CONVERTIBLE,
AT THE OPTION OF THE HOLDER, AT ANY TIME ON AND AFTER THE OCCURRENCE OF ANY OF THE EVENTS DESCRIBED BELOW, AND BEFORE 5:00 PM, NEW YORK, NEW YORK TIME, ON THE BUSINESS DAY IMMEDIATELY PRECEDING THE DATE OF REPAYMENT OF SUCH TRUST PIERS, WHETHER AT
STATED MATURITY OR UPON REDEMPTION, INTO A CASH AMOUNT AND, IF APPLICABLE, 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 TRUST PIERS
SUBJECT TO ADJUSTMENT. A HOLDER MAY CONVERT ANY PORTION OF THE LIQUIDATION AMOUNT OF THE TRUST PIERS INTO (A) A CASH AMOUNT EQUAL TO THE LESSER OF (I) THE AGGREGATE STATED LIQUIDATION AMOUNT OF THE TRUST PIERS TO BE CONVERTED OR (II) THE APPLICABLE
STOCK PRICE (AS DEFINED IN THE SUBORDINATED INDENTURE) MULTIPLIED BY THE CONVERSION RATIO THEN IN EFFECT (MULTIPLIED BY THE AGGREGATE STATED LIQUIDATION AMOUNT OF TRUST PIERS TO BE CONVERTED DIVIDED BY 50) AND (B) IF THE PRODUCT OF THE APPLICABLE
STOCK PRICE AND THE CONVERSION RATIO THEN IN EFFECT (MULTIPLIED BY THE AGGREGATE STATED LIQUIDATION AMOUNT OF TRUST PIERS TO BE CONVERTED DIVIDED BY 50) EXCEEDS THE AGGREGATE STATED LIQUIDATION AMOUNT OF THE TRUST PIERS TO BE CONVERTED, A NUMBER OF
SHARES OF COMMON STOCK EQUAL TO (I) THE AGGREGATE STATED LIQUIDATION AMOUNT OF TRUST PIERS TO BE CONVERTED DIVIDED BY $50 AND MULTIPLIED BY (II)(X) THE CONVERSION RATIO THEN IN EFFECT MINUS (Y) $50 DIVIDED BY THE APPLICABLE STOCK PRICE. 

  

 
UPON ANY EXERCISE OF SUCH CONVERSION RIGHT, THE CONVERSION AGENT SHALL EXCHANGE THE TRUST PIERS TO BE CONVERTED INTO CONVERTIBLE DEBENTURES ON THE BASIS OF
ONE TRUST PIERS PER $50 PRINCIPAL AMOUNT OF CONVERTIBLE DEBENTURES, AND IMMEDIATELY CONVERT SUCH AMOUNT OF CONVERTIBLE DEBENTURES INTO CASH AND, IF APPLICABLE, SHARES OF COMMON STOCK IN AN AMOUNT DETERMINED AS DESCRIBED IN THIS PARAGRAPH.

  
 Settlement in cash and, if applicable, shares of Common Stock
will occur on the second Trading Day following the final Trading Day of the 20 Trading Day period (the “Cash Settlement Averaging Period”) beginning on the Trading Day following the receipt by the Property Trustee of a Holder’s
conversion notice; 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 submits such
conversion notice during the period beginning 25 Trading Days preceding the maturity date of the Convertible 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 Convertible Debentures have been called for redemption, the Cash Settlement Averaging Period will be the 20 Trading Day period ending on the second
Trading Day preceding the Redemption Date. Such day will be the 22nd Trading Day following the Property Trustee’s receipt of a Holder’s conversion notice (assuming the 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) a Holder 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. 
  
 A Holder’s right to convert its Trust PIERS will arise only upon the occurrence of any of the following: 
  
 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 calendar quarter, then on and after the first day of the following calendar quarter (and only during such following calendar quarter), Holders may surrender
their Trust PIERS for conversion into shares of Common Stock at any time at their option until 5:00 p.m., New York, New York time, on the Business Day immediately preceding the Stated Maturity or earlier Redemption Date. 
  
 Conversion Rights Based on Notice of Redemption. A
Holder may surrender for conversion a Trust PIERS that has been called for redemption at any time prior to 5:00 p.m., New York, New York time, on the day that is two Business Days immediately preceding the date of redemption, even if such Trust
PIERS is not otherwise convertible at that time. 
  
 Conversion Rights Based on Trust PIERS Trading Price. Holders may also surrender a Trust PIERS 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 for such 10-Trading-Day period is less than a Specified Trigger 

  

 
Percentage (as defined below) of the average of the Conversion Values (as defined below) for the Trust PIERS for each day during such period. The
“Specified Trigger Percentage” shall 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. “Conversion Value” is equal to the product of the sale
price of Common Stock on a given day multiplied by the then-current Conversion Ratio. 
  
 Conversion Rights Based on Occurrence of Certain Corporate Transactions. 
  
 If: 
  

	 	(a)	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; 

  

	 	(b)	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 

  

	 	(c)	a Change of Control would have occurred but holders of Trust PIERS do not have the right to require the Company to repurchase their Trust PIERS 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 in the Trust Agreement 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 become convertible into such common stock (as described in clause (y) of the definition of “Change of Control” set forth
in the Trust Agreement), 

  
 then the Company shall
be required to notify the Holders of the Trust PIERS 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 Trust PIERS 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 Change of Control notice, in the case of a Change of Control. A Holder will not have the right to convert Trust PIERS as a result of a distribution if the Holder
has rights to participate, or will have such rights, in the distribution without conversion. 
  
 In addition, if the Depositor is party to a consolidation, merger or binding share exchange pursuant to which Common Stock will be
converted into cash, securities or other property, or if the Company sells, transfers or leases all or substantially all of its assets (each of which is referred to herein as a “Business Consolidation Transaction”), a Holder may
convert Trust PIERS at any time from and after the date which is 15 days prior to the anticipated effective date of such Business Consolidation Transaction until 15 days after the effective date of such Business Consolidation Transaction. At and
after the effective time of a Business Consolidation Transaction, the right to convert a Trust PIERS 

  

 
into cash and, if applicable, Common Stock will be changed into a right to convert the Trust PIERS into cash and, if applicable, the kind and amount of cash,
securities or other property which the Holder would have received if the Holder had converted such Trust PIERS immediately prior to the Business Consolidation Transaction. Such adjustment would be made assuming the Holders did not exercise any
rights of election as to the kind or amount of consideration receivable. The Company shall not become a party to any such transaction unless its terms are consistent with the conversion rights described in this paragraph. 
  
 A Holder may not exercise conversion rights in respect of any
Trust PIERS in respect of which such Holder is exercising its option to require redemption upon a Change of Control pursuant to Section 3.01 of the Third Supplemental Indenture to the Subordinated Indenture. The Trust PIERS shall be subject to the
further provisions relating to conversion set forth in the Trust Agreement and the Subordinated Indenture.

same to determine whether or not they conform to the requirements of this Guarantee; 
  
 (ii) the Guarantee Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer of the Guarantee
Trustee, unless it shall be proved that the Guarantee Trustee was negligent in ascertaining the pertinent facts upon which such judgment was made; 
  
 (iii) the Guarantee Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance

of its rights or powers, if the Guarantee Trustee shall have reasonable grounds for believing that the repayment of such funds or liability is not reasonably assured to it under the terms of this Guarantee or adequate indemnity against such risk or
liability is not reasonably assured to it.

which, upon receipt of such request, shall be promptly delivered by the Guarantor; 
  
 (iv) the Guarantee Trustee may consult with counsel of its choice, and the advice or opinion of such counsel with respect to legal matters
